La abeja europea (Apis mellifera), también conocida como abeja doméstica o abeja melífera, es una especie de himenóptero apócrito de la familia Apidae. Es la especie de abeja con mayor distribución en el mundo. Originaria de Europa, África y parte de Asia, fue introducida en América y Oceanía. Fue clasificada por Carlos Linneo en 1758. A partir de entonces numerosos taxónomos describieron variedades geográficas o subespecies que, en la actualidad, superan las treinta razas.

 

Cuando un apicultor se refiere a sus colmenas en forma colectiva lo hace desde un concepto intuitivo de colectividad, al hablar de los componentes de un apiario, habla lógicamente del conocimiento de la biología de las abejas, cuya naturaleza social hace que el individuo, en sí mismo, carezca de valor en favor de la colectividad de las abejas. Por todo ello se dice que la colmena es un superorganismo. Este superorganismo se comporta con sinergia que es el efecto producido por la interacción entre los componentes de un sistema que hace que el todo sea más que la suma de las partes individuales. A esta sinergia de conjunto demostrada por Farrar matemáticamente se le denomina regla de Farrar.

Plungercam 2 keeps in the spirit of the original plungercam by using of cheap plumbing equipment and affixing it to precision optics. This iteration eliminates the need for glue altogether, so all the optical components can be easily taken out and re-used elsewhere.

 

The main component is a rubberized pipe coupling, which I got for $7 at the always awesome Center hardware. The two adjustable steel bands will be used to hold the mount and lens securely in place. This particular one is two inches on the narrow end, and three on the wider end.

 

To fix the problem with the body cap mount teeth fraying, I decided to replace it with a T-mount T-mount adapter. I picked up the one I'm using for $3 from one of the closing Ritz camera stores.

 

I'm re using the $12 (from ebay) Zenza bronica medium format lens that was in plungercam 1. Since this was only held in place using a metal clip, it was easy to take it out and re-use it.

 

Total cost: $22 :)

Fangruida: human landing on Mars 10 cutting-edge technology

[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

-------------------------------------------------- -------------

Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.

Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.

1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.

Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant

High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.

Nuclear-powered spaceship for Use of nuclear power are three kinds:

The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.

The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,

Plasma Engine

Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "

The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.

Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.

Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.

3, high-performance nuclear rocket

Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.

Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works. 

Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust. 

A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.

Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction. 

Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.

Of course there are various research and development of rocket technology and technical solutions to try.

It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.

Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.

4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.

Plantar molt

After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space

Bone and muscle loss

Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.

Space Blindness

Space Blindness refers astronaut decreased vision.

Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.

Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

Osteoporosis and its complications ranked first in the space of disease risk.

Long-term health risks associated with flying Topics

The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.

Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.

Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections

Radiation hazards and protection

However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.

Space sickness

In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.

Robot surgeons

Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.

Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.

Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.

These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.

In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.

Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.

W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.

Fuel storage

In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.

This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.

Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.

When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards

Mars

Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.

Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.

Super rigid parachute to help slow the landing vehicle.

Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very

Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.

In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.

The moon is sterile. Mars is another case entirely.

With dust treatment measures.

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.

Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.

Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.

Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.

Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.

In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.

Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core

The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].

Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.

Lunar landscape

Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.

Regolith

TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.

Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology

Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project

[

"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.

In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.

In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.

Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.

Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.

.

After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.

Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.

The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.

Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.

Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.

Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.

Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown

Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.

Water quality monitoring sampling system:

Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.

Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.

Equipment cooling water system:

Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.

Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.

Safety Injection System: The main components of this system is the high-pressure injection pump.

Radioactive waste treatment systems:

Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.

Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

The original entrance to the theme park.

Over the years, Universal Studios Florida has not limited itself to attractions based on its own vast film library. It has occasionally licensed popular characters from other rival studios, many of whom did not operate theme parks themselves. Some examples include Ghostbusters and Men in Black, (Sony's Columbia Pictures), The Simpsons (20th Century Fox) and Shrek (DreamWorks Animation).

 

Many of the park's past and present attractions were developed with the actual creators of the films they were based on, and feature the original stars as part of the experience. Steven Spielberg helped create E.T. Adventure and was a creative consultant for Back to the Future: The Ride, Twister...Ride it Out, An American Tail Theatre, Jaws, Men in Black: Alien Attack and Transformers: The Ride.

 

In many current rides, the original stars reprised their film roles including: Rip Torn and Will Smith in Men in Black: Alien Attack, Brendan Fraser for Revenge of the Mummy: The Ride, Bill Paxton and Helen Hunt in Twister...Ride it Out, Arnold Schwarzenegger, Edward Furlong and Linda Hamilton reprised their roles for Terminator 2: 3-D Battle Across Time, Mike Myers, Eddie Murphy, Cameron Diaz, and John Lithgow for Shrek 4D, Steve Carell, Miranda Cosgrove, Dana Gaier, and Elsie Fisher reprised their roles from Despicable Me for Despicable Me: Minion Mayhem, and Peter Cullen and Frank Welker reprised their roles as Optimus Prime and Megatron for Transformers: The Ride.

 

In many former rides, the many original stars were also to reprise their film roles such as: Christopher Lloyd and Thomas F. Wilson in Back to the Future: The Ride, Roy Scheider recorded a voice over for the conclusion of Jaws, Alfred Hitchcock and Anthony Perkins appeared in Alfred Hitchcock: The Art of Making Movies, additionally, various Nicktoon voice actors reprised their roles in Jimmy Neutron's Nicktoon Blast.

 

Park history[edit]

 

From its inception in 1982,[3] Universal Studios Florida was designed as a theme park and a working studio. It was also the first time that Universal Studios had constructed an amusement park "from the ground up." However, the proposed project was put on hold until 1986, when a meeting between Steven Spielberg, a co-founder for the park, and Peter N. Alexander prompted for the creation of a Back to the Future simulator ride in addition to the already planned King Kong based ride.[4]

 

A major component of the original park in Hollywood is its studio tour, which featured several special-effects exhibits and encounters built into the tour, such as an attack by the great white shark from the film Jaws. For its Florida park, Universal Studios took the concepts of the Hollywood tour scenes and developed them into larger, stand-alone attractions. As an example, in Hollywood, the studio tour trams travel close to a shoreline and are "attacked" by Jaws before they travel to the next part of the tour. In Florida, guests entered the "Jaws" attraction and would board a boat touring the fictitious Amity Harbor, where they encountered the shark, then exited back into the park at the conclusion of the attraction. Universal Studios Florida originally had a Studio Tour attraction that visited the production facilities, but that tour has since been discontinued.

 

Branding[edit]

 

Previous slogans for Universal Studios Florida were: See the Stars. Ride the Movies. (1990 - 1998); No one makes believe like we do! (1990 - 1998); Ride the Movies (1998 - 2008); Jump into the Action (2008–2012). The current slogan is: Experience the Movies (2012–present).

The original entrance to the theme park.

Over the years, Universal Studios Florida has not limited itself to attractions based on its own vast film library. It has occasionally licensed popular characters from other rival studios, many of whom did not operate theme parks themselves. Some examples include Ghostbusters and Men in Black, (Sony's Columbia Pictures), The Simpsons (20th Century Fox) and Shrek (DreamWorks Animation).

 

Many of the park's past and present attractions were developed with the actual creators of the films they were based on, and feature the original stars as part of the experience. Steven Spielberg helped create E.T. Adventure and was a creative consultant for Back to the Future: The Ride, Twister...Ride it Out, An American Tail Theatre, Jaws, Men in Black: Alien Attack and Transformers: The Ride.

 

In many current rides, the original stars reprised their film roles including: Rip Torn and Will Smith in Men in Black: Alien Attack, Brendan Fraser for Revenge of the Mummy: The Ride, Bill Paxton and Helen Hunt in Twister...Ride it Out, Arnold Schwarzenegger, Edward Furlong and Linda Hamilton reprised their roles for Terminator 2: 3-D Battle Across Time, Mike Myers, Eddie Murphy, Cameron Diaz, and John Lithgow for Shrek 4D, Steve Carell, Miranda Cosgrove, Dana Gaier, and Elsie Fisher reprised their roles from Despicable Me for Despicable Me: Minion Mayhem, and Peter Cullen and Frank Welker reprised their roles as Optimus Prime and Megatron for Transformers: The Ride.

 

In many former rides, the many original stars were also to reprise their film roles such as: Christopher Lloyd and Thomas F. Wilson in Back to the Future: The Ride, Roy Scheider recorded a voice over for the conclusion of Jaws, Alfred Hitchcock and Anthony Perkins appeared in Alfred Hitchcock: The Art of Making Movies, additionally, various Nicktoon voice actors reprised their roles in Jimmy Neutron's Nicktoon Blast.

Alexander prompted for the creation of a Back to the Future simulator ride in addition to the already planned King Kong based ride.[4]

 

A major component of the original park in Hollywood is its studio tour, which featured several special-effects exhibits and encounters built into the tour, such as an attack by the great white shark from the film Jaws. For its Florida park, Universal Studios took the concepts of the Hollywood tour scenes and developed them into larger, stand-alone attractions. As an example, in Hollywood, the studio tour trams travel close to a shoreline and are "attacked" by Jaws before they travel to the next part of the tour. In Florida, guests entered the "Jaws" attraction and would board a boat touring the fictitious Amity Harbor, where they encountered the shark, then exited back into the park at the conclusion of the attraction. Universal Studios Florida originally had a Studio Tour attraction that visited the production facilities, but that tour has since been discontinued.

 

Branding[edit]

 

Previous slogans for Universal Studios Florida were: See the Stars. Ride the Movies. (1990 - 1998); No one makes believe like we do! (1990 - 1998); Ride the Movies (1998 - 2008); Jump into the Action (2008–2012). The current slogan is: Experience the Movies (2012–present).

 

Timeline[edit]

1986: Land clearing takes place on the swamp land purchased by MCA/Universal that would hold the park.

1987: Universal Studios Florida is announced at a press conference on the Hollywood property, with a planned opening date of December 1989.

1988: Universal Studios Florida's opening date is delayed from December, 1989 to May 1, 1990. Shortly following, MCA/Universal releases a video detailing the future park, which stars Christopher Lloyd as the Universal character Doc Brown interacting with the various attractions at the Florida park.[5] Universal Studios allows guests to witness the production of television shows and motion pictures in the Florida park's soundstages in middle 1988, while the rest of the studio/park is still under construction.[6]

1989: MCA/Universal Studios claims that The Walt Disney Company and its CEO, Michael Eisner copied several concepts of the Universal Studios Florida park, and integrated them into Disney's recently opened Disney/MGM Studios park.[7]

1990: On January 31, Universal Studios Florida's opening date is again delayed from May 1, 1990 to June 7, 1990.[8] Universal Studios Florida begins soft openings for the general public in late May.[9] Many of the park's attractions are not yet open at the time, and still under testing. Universal Studios Florida is officially opened with a grand opening style ceremony on June 7.[10] The park opens with five themed areas: The Front Lot (entrance area), Production Central, New York, San Francisco/Amity, Expo Center, Hollywood as well as a Lagoon located in the center of the park. The Front Lot and Production Central areas are referred to as "In Production", the New York section is referred to as "Now Shooting", the San Francisco and Amity sections are referred to as "On Location" and the Expo Center area is referred to as "The World of CineMagic Center". Nickelodeon Studios also opened on this day where there was a grand opening ceremony hosted by Marc Summers. Due to massive technical problems with the original Kongfrontation, Earthquake: The Big One and Jaws rides, Universal begins a temporary voucher service to allow guests to re-visit the studio/park when the attractions are operating.[10] Jaws is temporarily closed by Universal on September 30 due to persistent major technical problems. During the shut-down, Universal sues the original designer of the Jaws ride,[11] Ride & Show Engineering, and hires Totally Fun Company to create a re-designed version of most of the ride.

1991: Universal adds four new attractions to the park: The Blues Brothers Show, StreetBusters, The Screen Test Home Video Adventure and How to Make a Mega Movie Deal.[12] Back to the Future: The Ride officially opens in the World Expo Center area of the park, in a grand opening ceremony.[13] The ride is considered to be a success, and receives positive reception from theme park critics.[14] Fright Nights debuts at the park. In 1992, it is renamed to Halloween Horror Nights.

1993: Jaws is re-opened, with many scenes altered. MCA/Universal announces plans to expand Universal Studios Florida into the Universal City, Florida resort complex, including a second theme park and multiple hotels.[15]

1995: Universal Studios Florida celebrates its 5th anniversary. A Day in the Park with Barney opens in the World Expo area. The Production Studio Tour is closed due to a dwindle in the studios' recent Film/TV production.

1996: Terminator 2: 3-D Battle Across Time opens in the Hollywood area.[16]

1997: Universal announces that Ghostbusters Spooktacular will be replaced by Twister...Ride it Out, with a planned opening date of Spring 1998[17] Universal Studios announces that the sole Studio park will be expanded into the Universal Studios Escape, including the Islands of Adventure park, Universal CityWalk Orlando and multiple hotels. The Islands of Adventure Preview Center opens in the New York area, replacing The Screen Test Home Video Adventure. It is meant to give guests a preview of the up-coming Islands of Adventure park, as well as expansion of the Studio park into the Universal Studios Escape resort.

1998: The expansion begins as the original open parking lot for Universal Studios Florida is demolished and replaced by CityWalk and a parking garage complex.[18] Universal delays the opening of Twister...Ride it Out from March, 1998 to May 4, 1998 out of respect for the 42 deaths caused by a recent El Nino outbreak of tornadoes in the central Florida area. Twister...Ride it Out opens in the New York area, replacing Ghostbusters Spooktacular.[19] A new area of the park, Woody Woodpecker's Kidzone, is officially opened, holding the attractions Curious George Goes to Town, StarToons and the previously opened Fievel's Playland, E.T. Adventure, Animal Actors Stage and A Day in the Park with Barney; CityWalk opens outside of the park.

The previous icon of the Jaws ride is still a popular photo spot.

Like all theme parks, attractions are sometimes closed due to aging and replaced with more contemporary attractions. Universal has seen this happen several times. Some notable closures include Kongfrontation, Back to the Future: The Ride, The Funtastic World of Hanna-Barbera and Jaws. The closures of Kongfrontation, Back to the Future, and Jaws have been given homages by the park to honor veteran visitors who revered the former rides.

 

Park design[edit]

 

Main article: List of Universal Studios Florida attractions

 

Universal Studios Florida features seven themed areas all situated around a large lagoon. In 2012, this lagoon was the site of Universal’s Cinematic Spectacular: 100 Years of Movie Memories, a thematic display that showcased scenes from various Universal films, featuring lasers, projectors and fountains, and pyrotechnics.

 

The seven surrounding themed areas, clockwise from the entrance, are Production Central, New York, San Francisco, London/Diagon Alley, World Expo, Woody Woodpecker's Kidzone and Hollywood. Each area features a combination of rides, shows, attractions, character appearances, dining outlets and merchandise stores. A new area, based on Harry Potter's Diagon Alley was added to the park in the July of 2014.

“La Vela”. Ciudad BBVA. Un nuevo icono en la ciudad de Madrid

 

Calle Sauceda 28, c/v a C. Azul c/v C. Abetal Las Tablas Madrid

Arquitectos Herzog & de Meuron Architekten: Jacques Herzog y Pierre de Meuron. Diseño interior y diseño arquitectónico: Herzog & de Meuron (Arquitecto Core&Shell), SOM (Arquitectura interior). Colaboradores: Ortiz León Arquitectos. Concurso 2007, proyecto 2007-13, ejecución: fase 1: 2011-13, Finalización fase 2: 2015

  

BBVA (Banco Bilbao Vizcaya Argentaria) convocó a finales del año 2007 un Concurso Internacional de Ideas para la realización de su nueva sede en Madrid. Para la selección de los concursantes, la entidad financiera buscó a equipos de arquitectura de prestigio, con experiencia en diseño de proyectos para grandes corporaciones y comprometidos con la eficiencia económica, energética y medioambiental. Además de los ganadores, Herzog & De Meuron, participaron Zaha Hadid, Cesar Pelli-Ortiz & León, Estudio Lamela y Rafael de la Hoz. La nueva sede se sitúa en la periferia norte de Madrid, dentro del nuevo desarrollo denominado Las Tablas, junto a la a la Autovía A-1, rodeado de oficinas, edificios comerciales y residenciales; convirtiéndose en la primera imagen de la Ciudad de Madrid desde su acceso por el Norte, una nueva puerta de Europa. Cuando el banco adquirió el solar, una supermanzana que englobaba ocho parcelas con sus vías perimetrales, se encontraban en construcción cuatro edificios de oficinas, por lo que gran parte de ellos debía ser incorporada en el nuevo desarrollo.

Se trata de un complejo, con una superficie total construida de 252.000 m² de los que 114.000 m² se destinan a oficinas y servicios, para 6.000 puestos de trabajo y 3.000 plazas de aparcamiento, compuesto por siete edificios horizontales de tres alturas en cuyo centro se sitúa una plaza circular de 100 metros de diámetro en la que se erige el edificio principal, una torre elíptica irregular "La Vela". Cada uno de los siete edificios horizontales recibe el nombre de un continente, de norte a sur Oceanía, Asia, África, Europa, América del Sur, América del Norte y, al Oeste de la Plaza, Antártida. Las calles que los separan tienen por nombre el de los mares y océanos que unen los continentes, siendo éstas las calles Pacífico, Índico, Mediterráneo, Atlántico y Caribe. El edificio más emblemático es “La Vela”, denominación ganadora del concurso de ideas organizado por BBVA entre sus empleados para bautizar la torre. Se trata de un edificio de 93 metros de altura y 19 pisos, con 82 metros de diámetro y tan solo 16 m de ancho.

 

Los arquitectos autores del proyecto describen su propuesta:

Se trata de un “territorio sin cualidades”, un lugar desértico. Proponemos crear un jardín artificial, un oasis, generado desde dentro hacia fuera. Un lugar donde el medio natural y los edificios estén en equilibrio y funcionen como una pequeña ciudad. Una estructura lineal, compuesta por edificios de tres alturas, pequeñas calles y jardines, se despliega sobre el emplazamiento como una alfombra adaptándose a la topografía -que tiene una pendiente considerable -. En analogía a un jardín árabe, se genera un microclima fresco y húmedo. Cada puesto de trabajo dispone de una “vista verde”. Elegimos "internalizar" el complejo, para diseñarlo de forma única en torno a las necesidades internas de BBVA, dado que el entorno no tenían mucha identidad, simplemente no había mucho con lo que relacionarse. La disposición de poca altura, fomenta la comunicación: en lugar de tomar los ascensores, la gente camina por las escaleras que fomenten el intercambio informal; la transparencia visual maximizada da a todos una vista y genera un sentido de comunidad; mientras que las relativamente pequeñas unidades permiten a los empleados identificarse con su grupo de trabajo en particular.

En una zona interior de la manzana la alfombra se recorta siguiendo una forma casi circular y se posa en vertical. El resultado es una Plaza y una delgada Torre en forma de disco, como si esta masa se inclina hacia arriba para marcar el símbolo BBVA en el horizonte de Madrid. Plaza y Torre anclan el conjunto, proporcionando orientación. La entrada principal y varios servicios comunes del campus se conectan alrededor de la Plaza, en la que se plantan árboles que proveen sombra y una laguna que humidifica el aire y actúa, a su vez, como depósito de agua. Tanto los edificios como los jardines y las calles asumen el principio lineal. Cada área se distingue a través de árboles específicos, plantaciones de densidad y forma variable, que contribuyen a crear un carácter individual en el marco global de la alfombra. En contraste con las oficinas de baja altura, la torre ofrece otro tipo de espacio de trabajo, con vistas a la ciudad y a la sierra madrileña.

Tanto el sitio y la escala del desarrollo nos enfrentan al reto de encontrar una solución radical que elegimos para crear un oasis que mira hacia interior, no al anónimo paisaje urbano en el que se sitúa. Un lugar que establece un equilibrio entre lo natural y lo construido y que asume las funciones de ambos como un pequeña ciudad y un gran jardín.

 

Los edificios existentes se alteran para empatizar con las nuevas estructuras y crear oficinas y jardines lineales de escala similar. Se cortan o rellenan para ser integrados en el "tejido" en general.

La arquitectura muestra su estructura, un diseño que expresa una fuerte influencia de las condiciones ambientales. Largos y estrechos jardines interiores y calles, columnas de hormigón y losas en voladizo diseñadas para dar sombra y evitar la excesiva exposición al sol, lo que reduce la demanda de aire acondicionado. El acristalamiento en toda la altura de la planta ofrece buenas condiciones de luz diurna en las oficinas con el fin de reducir al mínimo la iluminación artificial. A lo largo de la periferia del complejo desarrollamos brise-soleil situados entre las losas de piso, diseñados de forma que se cortan en la parte inferior en un ángulo a fin de proporcionar más vista y la luz natural, donde se necesita menos protección, convirtiéndose en un elemento figurativo que varía en la dirección y tamaño de acuerdo con el ángulo de los rayos solares. El terreno en pendiente y los brise-soleil ayudan a conformar la fachada.

La fachada, de altísimo aislamiento térmico y acústico -doble vidrio, cámara de gas inerte,...- está conformada por lamas diseñadas por simulación energética para optimizar la entrada de luz natural, evitando la insolación directa pero permitiendo las vistas hacia el exterior. Los ensayos realizados reflejan que los sistemas de climatización necesitan dos horas menos de consumo diario en comparación con otro edificio sin estos elementos. Se trata de piezas fijas cuya orientación va en función del soleamiento y cambia en cada fachada, realizadas en acero, recubiertas de poliéster, reforzadas con fibra de carbono y lacadas en blanco. Tiene una componente de diseño que se basa en la escala humana, la figura de una persona levantada y sentada, las dos posturas que un trabajador tiene en la zona de oficinas, de ahí su equilibrio. Hay varios anchos de lamas para conseguir un superficie relativamente fluida de cara al exterior. Las lamas de una única altura se colocan en toda la fachada y las lamas dobles en todos los puntos de acceso o en las zonas de conexión. Debido a su colocación existe una superficie acristalada de 49.000 m² que permitiendo que el 90 % del interior tenga luz natural con un gran ahorro energético.

La cubierta se ha tratado como la quinta fachada del complejo, se ha realizado una zonificación por colores, con superficies ajardinadas y agrupando las instalaciones.

Los edificios de oficinas tienen siempre 3 plantas, baja más dos, pero debido a la topografía del solar, los forjados se van adaptando para que siempre se creen plantas con vistas al exterior. En las oficinas desaparecen por completo los despachos cerrados, nadie en el banco salvo el consejo tendrá despacho. Para ellos se crean tres estándares de puestos modulares para que pueda ser muy flexible la ubicación de los mismos. Existen zonas de reunión informal, siendo un elemento de modulación.

La Vela tiene 16 metros de ancho por una longitud de largo que varía, ya que la curvatura hace que la planta tenga diferente longitud en cada nivel. La planta que más longitud tiene es 82 metros. Este volumen se eleva 19 plantas sobre rasante y 3 bajo rasante. Tiene una altura de 93 m desde la plaza. El cerramiento tiene la misma solución que el resto del complejo, teniendo menos conductividad térmica con un sistema de panel de perfilería de aluminio extrusionado, compuesto por montantes. El alzado de la vela se utiliza a distintas escalas en todo el proyecto, es un símbolo. Parece que es un ovoide, pero es una geometría distinta con 36 radios de curvatura diferentes. La orientación del volumen es norte-sur, por ello al tener un cerramiento de vidrio se plantea en lado sur unos voladizos de 1,40 m para que la incidencia solar en ningún momento sea un problema en el interior. El revestimiento de exterior de la curvatura es de placas de acero inoxidable con un tratamiento para que no produzcan deslumbramientos.

El complejo de BBVA está diseñado para la obtención de la máxima distinción del certificado de sostenibilidad: el Leed de Oro. Uno de los sistemas más innovadores es el de refrigeración y calefacción, centenares de sondas detectan las necesidades de temperatura de cada estancia, miden el número de personas que hay en cada espacio y si no hay nadie, se apaga la refrigeración y la luz. Además hay un punto de reciclaje en cada lugar de trabajo y un número muy reducido de impresoras para tender al ahorro de papel. El agua de lluvia se recoge en las azoteas y la de las acequias y los inodoros es 100% reaprovechada.

Nervous system manipulation by electromagnetic fields from monitors

US 6506148 B2

  

Abstract

  

Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near ½ Hz or 2.4 Hz, such as to excite a sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of sufficient amplitudes to cause such excitation. It is therefore possible to manipulate the nervous system of a subject by pulsing images displayed on a nearby computer monitor or TV set. For the latter, the image pulsing may be imbedded in the program material, or it may be overlaid by modulating a video stream, either as an RF signal or as a video signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program. For certain monitors, pulsed electromagnetic fields capable of exciting sensory resonances in nearby subjects may be generated even as the displayed images are pulsed with subliminal intensity.

Description

  

BACKGROUND OF THE INVENTION

The invention relates to the stimulation of the human nervous system by an electromagnetic field applied externally to the body. A neurological effect of external electric fields has been mentioned by Wiener (1958), in a discussion of the bunching of brain waves through nonlinear interactions. The electric field was arranged to provide “a direct electrical driving of the brain”. Wiener describes the field as set up by a 10 Hz alternating voltage of 400 V applied in a room between ceiling and ground. Brennan (1992) describes in U.S. Pat. No. 5,169,380 an apparatus for alleviating disruptions in circadian rythms of a mammal, in which an alternating electric field is applied across the head of the subject by two electrodes placed a short distance from the skin.

 

A device involving a field electrode as well as a contact electrode is the “Graham Potentializer” mentioned by Hutchison (1991). This relaxation device uses motion, light and sound as well as an alternating electric field applied mainly to the head. The contact electrode is a metal bar in Ohmic contact with the bare feet of the subject, and the field electrode is a hemispherical metal headpiece placed several inches from the subject's head.

 

In these three electric stimulation methods the external electric field is applied predominantly to the head, so that electric currents are induced in the brain in the physical manner governed by electrodynamics. Such currents can be largely avoided by applying the field not to the head, but rather to skin areas away from the head. Certain cutaneous receptors may then be stimulated and they would provide a signal input into the brain along the natural pathways of afferent nerves. It has been found that, indeed, physiological effects can be induced in this manner by very weak electric fields, if they are pulsed with a frequency near ½ Hz. The observed effects include ptosis of the eyelids, relaxation, drowziness, the feeling of pressure at a centered spot on the lower edge of the brow, seeing moving patterns of dark purple and greenish yellow with the eyes closed, a tonic smile, a tense feeling in the stomach, sudden loose stool, and sexual excitement, depending on the precise frequency used, and the skin area to which the field is applied. The sharp frequency dependence suggests involvement of a resonance mechanism.

 

It has been found that the resonance can be excited not only by externally applied pulsed electric fields, as discussed in U.S. Pat. Nos. 5,782,874, 5,899,922, 6,081,744, and 6,167,304, but also by pulsed magnetic fields, as described in U.S. Pat. Nos. 5,935,054 and 6,238,333, by weak heat pulses applied to the skin, as discussed in U.S. Pat. Nos. 5,800,481 and 6,091,994, and by subliminal acoustic pulses, as described in U.S. Pat. No. 6,017,302. Since the resonance is excited through sensory pathways, it is called a sensory resonance. In addition to the resonance near ½ Hz, a sensory resonance has been found near 2.4 Hz. The latter is characterized by the slowing of certain cortical processes, as discussed in the '481, '922, '302, '744, '944, and '304 patents.

 

The excitation of sensory resonances through weak heat pulses applied to the skin provides a clue about what is going on neurologically. Cutaneous temperature-sensing receptors are known to fire spontaneously. These nerves spike somewhat randomly around an average rate that depends on skin temperature. Weak heat pulses delivered to the skin in periodic fashion will therefore cause a slight frequency modulation (fm) in the spike patterns generated by the nerves. Since stimulation through other sensory modalities results in similar physiological effects, it is believed that frequency modulation of spontaneous afferent neural spiking patterns occurs there as well.

 

It is instructive to apply this notion to the stimulation by weak electric field pulses administered to the skin. The externally generated fields induce electric current pulses in the underlying tissue, but the current density is much too small for firing an otherwise quiescent nerve. However, in experiments with adapting stretch receptors of the crayfish, Terzuolo and Bullock (1956) have observed that very small electric fields can suffice for modulating the firing of already active nerves. Such a modulation may occur in the electric field stimulation under discussion.

 

Further understanding may be gained by considering the electric charges that accumulate on the skin as a result of the induced tissue currents. Ignoring thermodynamics, one would expect the accumulated polarization charges to be confined strictly to the outer surface of the skin. But charge density is caused by a slight excess in positive or negative ions, and thermal motion distributes the ions through a thin layer. This implies that the externally applied electric field actually penetrates a short distance into the tissue, instead of stopping abruptly at the outer skin surface. In this manner a considerable fraction of the applied field may be brought to bear on some cutaneous nerve endings, so that a slight modulation of the type noted by Terzuolo and Bullock may indeed occur.

 

The mentioned physiological effects are observed only when the strength of the electric field on the skin lies in a certain range, called the effective intensity window. There also is a bulk effect, in that weaker fields suffice when the field is applied to a larger skin area. These effects are discussed in detail in the '922 patent.

 

Since the spontaneous spiking of the nerves is rather random and the frequency modulation induced by the pulsed field is very shallow, the signal to noise ratio (S/N) for the fm signal contained in the spike trains along the afferent nerves is so small as to make recovery of the fm signal from a single nerve fiber impossibile. But application of the field over a large skin area causes simultaneous stimulation of many cutaneous nerves, and the fm modulation is then coherent from nerve to nerve. Therefore, if the afferent signals are somehow summed in the brain, the fm modulations add while the spikes from different nerves mix and interlace. In this manner the S/N can be increased by appropriate neural processing. The matter is discussed in detail in the '874 patent. Another increase in sensitivity is due to involving a resonance mechanism, wherein considerable neural circuit oscillations can result from weak excitations.

 

An easily detectable physiological effect of an excited ½ Hz sensory resonance is ptosis of the eyelids. As discussed in the '922 patent, the ptosis test involves first closing the eyes about half way. Holding this eyelid position, the eyes are rolled upward, while giving up voluntary control of the eyelids. The eyelid position is then determined by the state of the autonomic nervous system. Furthermore, the pressure excerted on the eyeballs by the partially closed eyelids increases parasympathetic activity. The eyelid position thereby becomes somewhat labile, as manifested by a slight flutter. The labile state is sensitive to very small shifts in autonomic state. The ptosis influences the extent to which the pupil is hooded by the eyelid, and thus how much light is admitted to the eye. Hence, the depth of the ptosis is seen by the subject, and can be graded on a scale from 0 to 10.

 

In the initial stages of the excitation of the ½ Hz sensory resonance, a downward drift is detected in the ptosis frequency, defined as the stimulation frequency for which maximum ptosis is obtained. This drift is believed to be caused by changes in the chemical milieu of the resonating neural circuits. It is thought that the resonance causes perturbations of chemical concentrations somewhere in the brain, and that these perturbations spread by diffusion to nearby resonating circuits. This effect, called “chemical detuning”, can be so strong that ptosis is lost altogether when the stimulation frequency is kept constant in the initial stages of the excitation. Since the stimulation then falls somewhat out of tune, the resonance decreases in amplitude and chemical detuning eventually diminishes. This causes the ptosis frequency to shift back up, so that the stimulation is more in tune and the ptosis can develop again. As a result, for fixed stimulation frequencies in a certain range, the ptosis slowly cycles with a frequency of several minutes. The matter is discussed in the '302 patent.

 

The stimulation frequencies at which specific physiological effects occur depend somewhat on the autonomic nervous system state, and probably on the endocrine state as well.

 

Weak magnetic fields that are pulsed with a sensory resonance frequency can induce the same physiological effects as pulsed electric fields. Unlike the latter however, the magnetic fields penetrate biological tissue with nearly undiminished strength. Eddy currents in the tissue drive electric charges to the skin, where the charge distributions are subject to thermal smearing in much the same way as in electric field stimulation, so that the same physiological effects develop. Details are discussed in the '054 patent.

SUMMARY

Computer monotors and TV monitors can be made to emit weak low-frequency electromagnetic fields merely by pulsing the intensity of displayed images. Experiments have shown that the ½ Hz sensory resonance can be excited in this manner in a subject near the monitor. The 2.4 Hz sensory resonance can also be excited in this fashion. Hence, a TV monitor or computer monitor can be used to manipulate the nervous system of nearby people.

 

The implementations of the invention are adapted to the source of video stream that drives the monitor, be it a computer program, a TV broadcast, a video tape or a digital video disc (DVD).

 

For a computer monitor, the image pulses can be produced by a suitable computer program. The pulse frequency may be controlled through keyboard input, so that the subject can tune to an individual sensory resonance frequency. The pulse amplitude can be controlled as well in this manner. A program written in Visual Basic(R) is particularly suitable for use on computers that run the Windows 95(R) or Windows 98(R) operating system. The structure of such a program is described. Production of periodic pulses requires an accurate timing procedure. Such a procedure is constructed from the GetTimeCount function available in the Application Program Interface (API) of the Windows operating system, together with an extrapolation procedure that improves the timing accuracy.

 

Pulse variability can be introduced through software, for the purpose of thwarting habituation of the nervous system to the field stimulation, or when the precise resonance frequency is not known. The variability may be a pseudo-random variation within a narrow interval, or it can take the form of a frequency or amplitude sweep in time. The pulse variability may be under control of the subject.

 

The program that causes a monitor to display a pulsing image may be run on a remote computer that is connected to the user computer by a link; the latter may partly belong to a network, which may be the Internet.

 

For a TV monitor, the image pulsing may be inherent in the video stream as it flows from the video source, or else the stream may be modulated such as to overlay the pulsing. In the first case, a live TV broadcast can be arranged to have the feature imbedded simply by slightly pulsing the illumination of the scene that is being broadcast. This method can of course also be used in making movies and recording video tapes and DVDs.

 

Video tapes can be edited such as to overlay the pulsing by means of modulating hardware. A simple modulator is discussed wherein the luminance signal of composite video is pulsed without affecting the chroma signal. The same effect may be introduced at the consumer end, by modulating the video stream that is produced by the video source. A DVD can be edited through software, by introducing pulse-like variations in the digital RGB signals. Image intensity pulses can be overlaid onto the analog component video output of a DVD player by modulating the luminance signal component. Before entering the TV set, a television signal can be modulated such as to cause pulsing of the image intensity by means of a variable delay line that is connected to a pulse generator.

 

Certain monitors can emit electromagnetic field pulses that excite a sensory resonance in a nearby subject, through image pulses that are so weak as to be subliminal. This is unfortunate since it opens a way for mischievous application of the invention, whereby people are exposed unknowingly to manipulation of their nervous systems for someone else's purposes. Such application would be unethical and is of course not advocated. It is mentioned here in order to alert the public to the possibility of covert abuse that may occur while being online, or while watching TV, a video, or a DVD.

DETAILED DESCRIPTION

Computer monitors and TV monitors emit electromagnetic fields. Part of the emission occurs at the low frequencies at which displayed images are changing. For instance, a rythmic pulsing of the intensity of an image causes electromagnetic field emission at the pulse frequency, with a strength proportional to the pulse amplitude. The field is briefly referred to as “screen emission”. In discussing this effect, any part or all what is displayed on the monitor screen is called an image. A monitor of the cathode ray tube (CRT) type has three electron beams, one for each of the basic colors red, green, and blue. The intensity of an image is here defined as

 

I=∫j dA,  (1)

 

where the integral extends over the image, and

 

j=jr+jg+jb,  (2)

 

jr, jg, and jb being the electric current densities in the red, green, and blue electron beams at the surface area dA of the image on the screen. The current densities are to be taken in the distributed electron beam model, where the discreteness of pixels and the raster motion of the beams are ignored, and the back of the monitor screen is thought to be irradiated by diffuse electron beams. The beam current densities are then functions of the coordinates x and y over the screen. The model is appropriate since we are interested in the electromagnetic field emision caused by image pulsing with the very low frequencies of sensory resonances, whereas the emissions with the much higher horizontal and vertical sweep frequencies are of no concern. For a CRT the intensity of an image is expressed in millamperes.

 

For a liquid crystal display (LCD), the current densities in the definition of image intensity are to be replaced by driving voltages, multiplied by the aperture ratio of the device. For an LCD, image intensities are thus expressed in volts.

 

It will be shown that for a CRT or LCD screen emissions are caused by fluctuations in image intensity. In composite video however, intensity as defined above is not a primary signal feature, but luminance Y is. For any pixel one has

 

Y=0.299R+0.587G+0.114B,  (3)

 

where R, G, and B are the intensities of the pixel respectively in red, green and blue, normalized such as to range from 0 to 1. The definition (3) was provided by the Commission Internationale de l'Eclairage (CIE), in order to account for brightness differences at different colors, as perceived by the human visual system. In composite video the hue of the pixel is determined by the chroma signal or chrominance, which has the components R-Y and B-Y It follows that pulsing pixel luminance while keeping the hue fixed is equivalent to pulsing the pixel intensity, up to an amplitude factor. This fact will be relied upon when modulating a video stream such as to overlay image intensity pulses.

 

It turns out that the screen emission has a multipole expansion wherein both monopole and dipole contributions are proportional to the rate of change of the intensity I of (1). The higher order multipole contributions are proportional to the rate of change of moments of the current density j over the image, but since these contributions fall off rapidly with distance, they are not of practical importance in the present context. Pulsing the intensity of an image may involve different pulse amplitudes, frequencies, or phases for different parts of the image. Any or all of these features may be under subject control.

 

The question arises whether the screen emission can be strong enough to excite sensory resonances in people located at normal viewing distances from the monitor. This turns out to be the case, as shown by sensory resonance experiments and independently by measuring the strength of the emitted electric field pulses and comparing the results with the effective intensity window as explored in earlier work.

 

One-half Hertz sensory resonance experiments have been conducted with the subject positioned at least at normal viewing distance from a 15″ computer monitor that was driven by a computer program written in Visual Basic(R), version 6.0 (VB6). The program produces a pulsed image with uniform luminance and hue over the full screen, except for a few small control buttons and text boxes. In VB6, screen pixel colors are determined by integers R, G, and B, that range from 0 to 255, and set the contributions to the pixel color made by the basic colors red, green, and blue. For a CRT-type monitor, the pixel intensities for the primary colors may depend on the RGB values in a nonlinear manner that will be discussed. In the VB6 program the RGB values are modulated by small pulses ΔR, ΔG, ΔB, with a frequency that can be chosen by the subject or is swept in a predetermined manner. In the sensory resonance experiments mentioned above, the ratios ΔR/R, ΔG/G, and ΔB/B were always smaller than 0.02, so that the image pulses are quite weak. For certain frequencies near ½ Hz, the subject experienced physiological effects that are known to accompany the excitation of the ½ Hz sensory resonance as mentioned in the Background Section. Moreover, the measured field pulse amplitudes fall within the effective intensity window for the ½ Hz resonance, as explored in earlier experiments and discussed in the '874, '744, '922, and '304 patents. Other experiments have shown that the 2.4 Hz sensory resonance can be exited as well by screen emissions from monitors that display pulsed images.

 

These results confirm that, indeed, the nervous system of a subject can be manipulated through electromagnetic field pulses emitted by a nearby CRT or LCD monitor which displays images with pulsed intensity.

 

The various implementations of the invention are adapted to the different sources of video stream, such as video tape, DVD, a computer program, or a TV broadcast through free space or cable. In all of these implementations, the subject is exposed to the pulsed electromagnetic field that is generated by the monitor as the result of image intensity pulsing. Certain cutaneous nerves of the subject exhibit spontaneous spiking in patterns which, although rather random, contain sensory information at least in the form of average frequency. Some of these nerves have receptors that respond to the field stimulation by changing their average spiking frequency, so that the spiking patterns of these nerves acquire a frequency modulation, which is conveyed to the brain. The modulation can be particularly effective if it has a frequency at or near a sensory resonance frequency. Such frequencies are expected to lie in the range from 0.1 to 15 Hz.

 

An embodiment of the invention adapted to a VCR is shown in FIG. 1, where a subject 4 is exposed to a pulsed electric field 3 and a pulsed magnetic field 39 that are emitted by a monitor 2, labeled “MON”, as the result of pulsing the intensity of the displayed image. The image is here generated by a video casette recorder 1, labeled “VCR”, and the pulsing of the image intensity is obtained by modulating the composite video signal from the VCR output. This is done by a video modulator 5, labeled “VM”, which responds to the signal from the pulse generator 6, labeled “GEN”. The frequency and amplitude of the image pulses can be adjusted with the frequency control 7 and amplitude control 8. Frequency and amplitude adjustments can be made by the subject.

 

The circuit of the video modulator 5 of FIG. 1 is shown in FIG. 2, where the video amplifiers 11 and 12 process the composite video signal that enters at the input terminal 13. The level of the video signal is modulated slowly by injecting a small bias current at the inverting input 17 of the first amplifier 11. This current is caused by voltage pulses supplied at the modulation input 16, and can be adjusted through the potentiometer 15. Since the noninverting input of the amplifier is grounded, the inverting input 17 is kept essentially at ground potential, so that the bias current is is not influenced by the video signal. The inversion of the signal by the first amplifier 11 is undone by the second amplifier 12. The gains of the amplifiers are chosen such as to give a unity overall gain. A slowly varying current injected at the inverting input 17 causes a slow shift in the “pseudo-dc” level of the composite video signal, here defined as the short-term average of the signal. Since the pseudo-dc level of the chroma signal section determines the luminance, the latter is modulated by the injected current pulses. The chroma signal is not affected by the slow modulation of the pseudodc level, since that signal is determined by the amplitude and phase with respect to the color carrier which is locked to the color burst. The effect on the sync pulses and color bursts is of no consequence either if the injected current pulses are very small, as they are in practice. The modulated composite video signal, available at the output 14 in FIG. 2, will thus exhibit a modulated luminance, whereas the chroma signal is unchanged. In the light of the foregoing discussion about luminance and intensity, it follows that the modulator of FIG. 2 causes a pulsing of the image intensity I. It remains to give an example how the pulse signal at the modulation input 16 may be obtained. FIG. 3 shows a pulse generator that is suitable for this purpose, wherein the RC timer 21 (Intersil ICM7555) is hooked up for astable operation and produces a square wave voltage with a frequency that is determined by capacitor 22 and potentiometer 23. The timer 21 is powered by a battery 26, controlled by the switch 27. The square wave voltage at output 25 drives the LED 24, which may be used for monitoring of the pulse frequency, and also serves as power indicator. The pulse output may be rounded in ways that are well known in the art. In the setup of FIG. 1, the output of VCR 1 is connected to the video input 13 of FIG. 2, and the video output 14 is connected to the monitor 2 of FIG. 1.

 

In the preferred embodiment of the invention, the image intensity pulsing is caused by a computer program. As shown in FIG. 4, monitor 2, labeled “MON”, is connected to computer 31 labeled “COMPUTER”, which runs a program that produces an image on the monitor and causes the image intensity to be pulsed. The subject 4 can provide input to the computer through the keyboard 32 that is connected to the computer by the connection 33. This input may involve adjustments of the frequency or the amplitude or the variability of the image intensity pulses. In particular, the pulse frequency can be set to a sensory resonance frequency of the subject for the purpose of exciting the resonance.

 

The structure of a computer program for pulsing image intensity is shown in FIG. 6. The program may be written in Visual Basic(R) version 6.0 (VB6), which involves the graphics interface familiar from the Windows(R) operating system. The images appear as forms equipped with user controls such as command buttons and scroll bars, together with data displays such as text boxes. A compiled VB6 program is an executable file. When activated, the program declares variables and functions to be called from a dynamic link library (DLL) that is attached to the operating system; an initial form load is performed as well. The latter comprises setting the screen color as specified by integers R, G, and B in the range 0 to 255, as mentioned above. In FIG. 6, the initial setting of the screen color is labeled as 50. Another action of the form load routine is the computation 51 of the sine function at eight equally spaced points, I=0 to 7, around the unit circle. These values are needed when modulating the RGB numbers. Unfortunately, the sine function is distorted by the rounding to integer RGB values that occurs in the VB6 program. The image is chosen to fill as much of the screen area as possible, and it has spatially uniform luminance and hue.

 

The form appearing on the monitor displays a command button for starting and stopping the image pulsing, together with scroll bars 52 and 53 respectively for adjustment of the pulse frequency F and the pulse amplitude A. These pulses could be initiated by a system timer which is activated upon the elapse of a preset time interval. However, timers in VB6 are too inaccurate for the purpose of providing the eight RGB adjustment points in each pulse cycle. An improvement can be obtained by using the GetTickCount function that is available in the Application Program Interface (API) of Windows 95(R) and Windows 98(R). The GetTickCount function returns the system time that has elapsed since starting Windows, expressed in milliseconds. User activation of the start button 54 provides a tick count TN through request 55 and sets the timer interval to TT miliseconds, in step 56. TT was previously calculated in the frequency routine that is activated by changing the frequency, denoted as step 52.

 

Since VB6 is an event-driven program, the flow chart for the program falls into disjoint pieces. Upon setting the timer interval to TT in step 56, the timer runs in the background while the program may execute subroutines such as adjustment of pulse frequency or amplitude. Upon elapse of the timer interval TT, the timer subroutine 57 starts execution with request 58 for a tick count, and in 59 an upgrade is computed of the time TN for the next point at which the RGB values are to be adjusted. In step 59 the timer is turned off, to be reactivated later in step 67. Step 59 also resets the parameter CR which plays a role in the extrapolation procedure 61 and the condition 60. For ease of understanding at this point, it is best to pretend that the action of 61 is simply to get a tick count, and to consider the loop controled by condition 60 while keeping CR equal to zero. The loop would terminate when the tick count M reaches or exceeds the time TN for the next phase point, at which time the program should adjust the image intensity through steps 63-65. For now step 62 is to be ignored also, since it has to do with the actual extrapolation procedure 61. The increments to the screen colors R1, G1, and B1 at the new phase point are computed according to the sine function, applied with the amplitude A that was set by the user in step 53. The number I that labels the phase point is incremented by unity in step 65, but if this results in I=8 the value is reset to zero in 66. Finally, the timer is reactivated in step 67, initiating a new ⅛-cycle step in the periodic progression of RGB adjustments.

 

A program written in this way would exhibit a large jitter in the times at which the RGB values are changed. This is due to the lumpiness in the tick counts returned by the GetTickCount function. The lumpiness may be studied separately by running a simple loop with C=GetTickCount, followed by writing the result C to a file. Inspection shows that C has jumped every 14 or 15 milliseconds, between long stretches of constant values. Since for a ½ Hz image intensity modulation the ⅛-cycle phase points are 250 ms apart, the lumpiness of 14 or 15 ms in the tick count would cause considerable inaccuracy. The full extrapolation procedure 61 is introduced in order to diminish the jitter to acceptable levels. The procedure works by refining the heavy-line staircase function shown in FIG. 8, using the slope RR of a recent staircase step to accurately determine the loop count 89 at which the loop controled by 60 needs to be exited. Details of the extrapolation procedure are shown in FIG. 7 and illustrated in FIG. 8. The procedure starts at 70 with both flags off, and CR=0, because of the assignment in 59 or 62 in FIG. 6. A tick count M is obtained at 71, and the remaining time MR to the next phase point is computed in 72. Conditions 77 and 73 are not satisfied and therefore passed vertically in the flow chart, so that only the delay block 74 and the assignments 75 are executed. Condition 60 of FIG. 6 is checked and found to be satisfied, so that the extrapolation procedure is reentered. The process is repeated until the condition 73 is met when the remaining time MR jumps down through the 15 ms level, shown in FIG. 8 as the transition 83. The condition 73 then directs the logic flow to the assignments 76, in which the number DM labeled by 83 is computed, and FLG1 is set. The computation of DM is required for finding the slope RR of the straight-line element 85. One also needs the “Final LM” 86, which is the number of loops traversed from step 83 to the next downward step 84, here shown to cross the MR=0 axis. The final LM is determined after repeatedly incrementing LM through the side loop entered from the FLG1=1 condition 77, which is now satisfied since FLG1 was set in step 76. At the transition 84 the condition 78 is met, so that the assignments 79 are executed. This includes computation of the slope RR of the line element 85, setting FLG2, and resetting FLG1. From here on, the extrapolation procedure increments CR in steps of RR while skipping tick counts until condition 60 of FIG. 6 is violated, the loop is exited, and the RGB values are adjusted.

 

A delay block 74 is used in order to stretch the time required for traversing the extrapolation procedure. The block can be any computation intensive subroutine such as repeated calculations of tangent and arc tangent functions.

 

As shown in step 56 of FIG. 6, the timer interval TT is set to 4/10 of the time TA from one RGB adjustment point to the next. Since the timer runs in the background, this arrangement provides an opportunity for execution of other processes such as user adjustment of frequency or amplitude of the pulses.

 

The adjustment of the frequency and other pulse parameters of the image intensity modulation can be made internally, i.e., within the running program. Such internal control is to be distinguished from the external control provided, for instance, in screen savers. In the latter, the frequency of animation can be modified by the user, but only after having exited the screen saver program. Specifically, in Windows 95(R) or Windows 98(R), to change the animation frequency requires stopping the screen saver execution by moving the mouse, whereafter the frequency may be adjusted through the control panel. The requirement that the control be internal sets the present program apart from so-called banners as well.

 

The program may be run on a remote computer that is linked to the user computer, as illustrated in FIG. 9. Although the monitor 2, labeled “MON”, is connected to the computer 31′, labeled “COMPUTER”, the program that pulses the images on the monitor 2 runs on the remoter computer 90, labeled “REMOTE COMPUTER”, which is connected to computer 31′ through a link 91 which may in part belong to a network. The network may comprise the Internet 92.

 

The monitor of a television set emits an electromagnetic field in much the same way as a computer monitor. Hence, a TV may be used to produce screen emissions for the purpose of nervous system manipulation. FIG. 5 shows such an arrangement, where the pulsing of the image intensity is achieved by inducing a small slowly pulsing shift in the frequency of the RF signal that enters from the antenna. This process is here called “frequency wobbling” of the RF signal. In FM TV, a slight slow frequency wobble of the RF signal produces a pseudo-dc signal level fluctuation in the composite video signal, which in turn causes a slight intensity fluctuation of the image displayed on the monitor in the same manner as discussed above for the modulator of FIG. 2. The frequency wobbling is induced by the wobbler 44 of FIG. 5 labeled “RFM”, which is placed in the antenna line 43. The wobbler is driven by the pulse generator 6, labeled “GEN”. The subject can adjust the frequency and the amplitude of the wobble through the tuning control 7 and the amplitude control 41. FIG. 10 shows a block diagram of the frequency wobbler circuit that employs a variable delay line 94, labelled “VDL”. The delay is determined by the signal from pulse generator 6, labelled “GEN”. The frequency of the pulses can be adjusted with the tuning control 7. The amplitude of the pulses is determined by the unit 98, labelled “MD”, and can be adjusted with the amplitude control 41. Optionally, the input to the delay line may be routed through a preprocessor 93, labelled “PRP”, which may comprise a selective RF amplifier and down converter; a complimentary up conversion should then be performed on the delay line output by a postprocessor 95, labelled “POP”. The output 97 is to be connected to the antenna terminal of the TV set.

 

The action of the variable delay line 94 may be understood as follows. Let periodic pulses with period L be presented at the input. For a fixed delay the pulses would emerge at the output with the same period L. Actually, the time delay T is varied slowly, so that it increases approximately by LdT/dt between the emergence of consecutive pulses at the device output. The pulse period is thus increased approximately by

 

ΔL=LdT/dt.  (4)

 

In terms of the frequency ∫, Eq. (4) implies approximately

 

Δ∫/∫=−dT/dt.  (5)

 

For sinusoidal delay T(t) with amplitude b and frequency g, one has

 

Δ∫/∫=−2πgb cos (2πgt),  (6)

 

which shows the frequency wobbling. The approximation is good for gb<<1, which is satisfied in practice. The relative frequency shift amplitude 2πgb that is required for effective image intensity pulses is very small compared to unity. For a pulse frequency g of the order of 1 Hz, the delay may have to be of the order of a millisecond. To accomodate such long delay values, the delay line may have to be implemented as a digital device. To do so is well within the present art. In that case it is natural to also choose digital implementations for the pulse generator 6 and the pulse amplitude controller 98, either as hardware or as software.

 

Pulse variability may be introduced for alleviating the need for precise tuning to a resonance frequency. This may be important when sensory resonance frequencies are not precisely known, because of the variation among individuals, or in order to cope with the frequency drift that results from chemical detuning that is discussed in the '874 patent. A field with suitably chosen pulse variability can then be more effective than a fixed frequency field that is out of tune. One may also control tremors and seizures, by interfering with the pathological oscillatory activity of neural circuits that occurs in these disorders. Electromagnetic fields with a pulse variability that results in a narrow spectrum of frequencies around the frequency of the pathological oscillatory activity may then evoke nerve signals that cause phase shifts which diminish or quench the oscillatory activity.

 

Pulse variability can be introduced as hardware in the manner described in the '304 patent. The variability may also be introduced in the computer program of FIG. 6, by setting FLG3 in step 68, and choosing the amplitude B of the frequency fluctuation. In the variability routine 46, shown in some detail in FIG. 13, FLG3 is detected in step 47, whereupon in steps 48 and 49 the pulse frequency F is modified pseudo randomly by a term proportional to B, every 4th cycle. Optionally, the amplitude of the image intensity pulsing may be modified as well, in similar fashion. Alternatively, the frequency and amplitude may be swept through an adjustable ramp, or according to any suitable schedule, in a manner known to those skilled in the art. The pulse variability may be applied to subliminal image intensity pulses.

 

When an image is displayed by a TV monitor in response to a TV broadcast, intensity pulses of the image may simply be imbedded in the program material. If the source of video signal is a recording medium, the means for pulsing the image intensity may comprise an attribute of recorded data. The pulsing may be subliminal. For the case of a video signal from a VCR, the pertinent data attribute is illustrated in FIG. 11, which shows a video signal record on part of a video tape 28. Depicted schematically are segments of the video signal in intervals belonging to lines in three image frames at different places along the tape. In each segment, the chroma signal 9 is shown, with its short-term average level 29 represented as a dashed line. The short-term average signal level, also called the pseudo-dc level, represents the luminance of the image pixels. Over each segment, the level is here constant because the image is for simplicity chosen as having a uniform luminance over the screen. However, the level is seen to vary from frame to frame, illustrating a luminance that pulses slowly over time. This is shown in the lower portion of the drawing, wherein the IRE level of the short-term chroma signal average is plotted versus time. The graph further shows a gradual decrease of pulse amplitude in time, illustrating that luminance pulse amplitude variations may also be an attribute of the recorded data on the video tape. As discussed, pulsing the luminance for fixed chrominance results in pulsing of the image intensity.

 

Data stream attributes that represent image intensity pulses on video tape or in TV signals may be created when producing a video rendition or making a moving picture of a scene, simply by pulsing the illumination of the scene. This is illustrated in FIG. 12, which shows a scene 19 that is recorded with a video camera 18, labelled “VR”. The scene is illuminated with a lamp 20, labelled “LAMP”, energized by an electric current through a cable 36. The current is modulated in pulsing fashion by a modulator 30, labeled “MOD”, which is driven by a pulse generator 6, labelled “GENERATOR”, that produces voltage pulses 35. Again, pulsing the luminance but not the chrominance amounts to pulsing the image intensity.

 

The brightness of monitors can usually be adjusted by a control, which may be addressable through a brightness adjustment terminal. If the control is of the analog type, the displayed image intensity may be pulsed as shown in FIG. 15, simply by a pulse generator 6, labeled “GEN”, that is connected to the brigthness adjustment terminal 88 of the monitor 2, labeled “MON”. Equivalent action can be provided for digital brightness controls, in ways that are well known in the art.

 

The analog component video signal from a DVD player may be modulated such as to overlay image intensity pulses in the manner illustrated in FIG. 17. Shown are a DVD player 102, labeled “DVD”, with analog component video output comprised of the luminance Y and chrominance C. The overlay is accomplished simply by shifting the luminance with a voltage pulse from generator 6, labeled “GENERATOR”. The generator output is applied to modulator 106, labeled “SHIFTER”. Since the luminance Y is pulsed without changing the chrominance C, the image intensity is pulsed. The frequency and amplitude of the image intensity pulses can be adjusted respectively with the tuner 7 and amplitude control 107. The modulator 105 has the same structure as the modulator of FIG. 2, and the pulse amplitude control 107 operates the potentiometer 15 of FIG. 2. The same procedure can be followed for editing a DVD such as to overlay image intensity pulses, by processing the modulated luminance signal through an analog-to-digital converter, and recording the resulting digital stream onto a DVD, after appropriate compression. Alternatively, the digital luminance data can be edited by electronic reading of the signal, decompression, altering the digital data by software, and recording the resulting digital signal after proper compression, all in a manner that is well known in the art.

 

The mechanism whereby a CRT-type monitor emits a pulsed electromagnetic field when pulsing the intensity of an image is illustrated in FIG. 14. The image is produced by an electron beam 10 which impinges upon the backside 88 of the screen, where the collisions excite phosphors that subsequently emit light. In the process, the electron beam deposits electrons 18 on the screen, and these electrons contribute to an electric field 3 labelled “E”. The electrons flow along the conductive backside 88 of the screen to the terminal 99 which is hooked up to the high-voltage supply 40, labelled “HV”. The circuit is completed by the ground connection of the supply, the video amplifier 87, labeled “VA”, and its connection to the cathodes of the CRT. The electron beams of the three electron guns are collectively shown as 10, and together the beams carry a current J. The electric current J flowing through the described circuit induces a magnetic field 39, labeled “B”. Actually, there are a multitude of circuits along which the electron beam current is returned to the CRT cathodes, since on a macroscopic scale the conductive back surface 88 of the screen provides a continuum of paths from the beam impact point to the high-voltage terminal 99. The magnetic fields induced by the currents along these paths partially cancel each other, and the resulting field depends on the location of the pixel that is addressed. Since the beams sweep over the screen through a raster of horizontal lines, the spectrum of the induced magnetic field contains strong peaks at the horizontal and vertical frequencies. However, the interest here is not in fields at those frequencies, but rather in emissions that result from an image pulsing with the very low frequencies appropriate to sensory resonances. For this purpose a diffuse electron current model suffices, in which the pixel discreteness and the raster motion of the electron beams are ignored, so that the beam current becomes diffuse and fills the cone subtended by the displayed image. The resulting low-frequency magnetic field depends on the temporal changes in the intensity distribution over the displayed image. Order-of-magnitude estimates show that the low-frequency magnetic field, although quite small, may be sufficient for the excitation of sensory resonances in subjects located at a normal viewing distance from the monitor.

 

The monitor also emits a low-frequency electric field at the image pulsing frequency. This field is due in part to the electrons 18 that are deposited on the screen by the electron beams 10. In the diffuse electron beam model, screen conditions are considered functions of the time t and of the Cartesian coordinates x and y over a flat CRT screen.

 

The screen electrons 18 that are dumped onto the back of the screen by the sum j(x,y,t) of the diffuse current distributions in the red, green, and blue electron beams cause a potential distribution V(x,y,t) which is influenced by the surface conductivity σ on the back of the screen and by capacitances. In the simple model where the screen has a capacitance distribution c(x,y) to ground and mutual capacitances between parts of the screen at different potentials are neglected, a potential distribution V(x,y,t) over the screen implies a surface charge density distribution

 

q=Vc(x,y),  (7)

 

and gives rise to a current density vector along the screen,

 

j s=−σgrads V,  (8)

 

where grads is the gradient along the screen surface. Conservation of electric charge implies

 

j=c{dot over (V)}−div s (σgrad s V),  (9)

 

where the dot over the voltage denotes the time derivative, and divs is the divergence in the screen surface. The partial differential equation (9) requires a boundary condition for the solution V(x,y,t) to be unique. Such a condition is provided by setting the potential at the rim of the screen equal to the fixed anode voltage. This is a good approximation, since the resistance Rr between the screen rim and the anode terminal is chosen small in CRT design, in order to keep the voltage loss JRr to a minimum, and also to limit low-frequency emissions.

 

Something useful can be learned from special cases with simple solutions. As such, consider a circular CRT screen of radius R with uniform conductivity, showered in the back by a diffuse electron beam with a spatially uniform beam current density that is a constant plus a sinusoidal part with frequency ∫. Since the problem is linear, the voltage V due to the sinusoidal part of the beam current can be considered separately, with the boundary condition that V vanish at the rim of the circular screen. Eq. (9) then simplifies to

 

V″+V″/r−i2π∫cn V=−Jη/A, r≦R,  (10)

 

where r is a radial coordinate along the screen with its derivative denoted by a prime, η=1/σ is the screen resistivity, A the screen area, J the sinusoidal part of the total beam current, and i=(−1), the imaginary unit. Our interest is in very low pulse frequencies ∫ that are suitable for excitation of sensory resonances. For those frequencies and for practical ranges for c and η, the dimensionless number 2π∫cAη is very much smaller than unity, so that it can be neglected in Eq. (10). The boundary value problem then has the simple solution V  ( r ) = J     η 4  π  ( 1 - ( r / R ) 2 ) . ( 11 )

Figure US06506148-20030114-M00001

 

In deriving (11) we neglected the mutual capacitance between parts of the screen that are at different potentials. The resulting error in (10) is negligible for the same reason that the i2π∫cAη term in (10) can be neglected.

 

The potential distribution V(r) of (11) along the screen is of course accompanied by electric charges. The field lines emanating from these charges run mainly to conductors behind the screen that belong to the CRT structure and that are either grounded or connected to circuitry with a low impedance path to ground. In either case the mentioned conductors must be considered grounded in the analysis of charges and fields that result from the pulsed component J of the total electron beam current. The described electric field lines end up in electric charges that may be called polarization charges since they are the result of the polarization of the conductors and circuitry by the screen emission. To estimate the pulsed electric field, a model is chosen where the mentioned conductors are represented together as a grounded perfectly conductive disc of radius R, positioned a short distance δ behind the screen, as depicted in FIG. 16. Since the grounded conductive disc carries polarization charges, it is called the polarization disc. FIG. 16 shows the circular CRT screen 88 and the polarization disc 101, briefly called “plates”. For small distances δ, the capacitance density between the plates of opposite polarity is nearly equal to ε/δ, where ε is the permittivity of free space. The charge distributions on the screen and polarization disc are respectively εV(r)/δ+q0 and −εV(r)/δ+q0, where the εV(r)/δ terms denote opposing charge densities at the end of the dense field lines that run between the two plates. That the part q0 is needed as well will become clear in the sequel.

 

The charge distributions εV(r)/δ+q0 and −εV(r)/δ+q0 on the two plates have a dipole moment with the density D  ( r ) = εV  ( r ) = J     ηε 4  π  ( 1 - ( r / R ) 2 ) , ( 12 )

Figure US06506148-20030114-M00002

 

directed perpendicular to the screen. Note that the plate separation δ has dropped out. This means that the precise location of the polarization charges is not critical in the present model, and further that δ may be taken as small as desired. Taking δ to zero, one thus arrives at the mathematical model of pulsed dipoles distributed over the circular CRT screen. The field due to the charge distribution q0 will be calculated later.

 

The electric field induced by the distributed dipoles (12) can be calculated easily for points on the centerline of the screen, with the result E  ( z ) = V  ( 0 ) R  { 2  ρ / R - R / ρ - 2   z  / R } , ( 13 )

Figure US06506148-20030114-M00003

 

where V(0) is the pulse voltage (11) at the screen center, ρ the distance to the rim of the screen, and z the distance to the center of the screen. Note that V(0) pulses harmonically with frequency ∫, because in (11) the sinusoidal part J of the beam current varies in this manner.

 

The electric field (13) due to the dipole distribution causes a potential distribution V(r)/2 over the screen and a potential distribution of −V(r)/2 over the polarization disc, where V(r) is nonuniform as given by (11). But since the polarization disc is a perfect conductor it cannot support voltage gradients, and therefore cannot have the potential distribution −V(r)/2. Instead, the polarization disc is at ground potential. This is where the charge distribution q0(r) comes in; it must be such as to induce a potential distribution V(r)/2 over the polarization disc. Since the distance between polarization disc and screen vanishes in the mathematical model, the potential distribution V(r)/2 is induced over the screen as well. The total potential over the monitor screen thus becomes V(r) of (11), while the total potential distribution over the polarization disc becomes uniformly zero. Both these potential distributions are as physically required. The electric charges q0 are moved into position by polarization and are partly drawn from the earth through the ground connection of the CRT.

 

In our model the charge distribution q0 is located at the same place as the dipole distribution, viz., on the plane z=0 within the circle with radius R. At points on the center line of the screen, the electric field due to the monopole distribution q0 is calculated in the following manner. As discussed, the monopoles must be such that they cause a potential φ0 that is equal to V(r)/2 over the disc with radius R centered in the plane z=0. Although the charge distribution q0(r) is uniquely defined by this condition, it cannot be calculated easily in a straightforward manner. The difficulty is circumvented by using an intermediate result derived from Excercise 2 on page 191 of Kellogg (1953), where the charge distribution over a thin disc with uniform potential is given. By using this result one readily finds the potential φ*(z) on the axis of this disc as φ *  ( z ) = 2 π  V *  β  ( R 1 ) , ( 14 )

Figure US06506148-20030114-M00004

 

where β(R1) is the angle subtended by the disc radius R1, as viewed from the point z on the disc axis, and V* is the disc potential. The result is used here in an attempt to construct the potential φ0(z) for a disc with the nonuniform potential V(r)/2, by the ansatz of writing the field as due to a linear combination of abstract discs with various radii R1 and potentials, all centered in the plane z=0. In the ansatz the potential on the symmetry axis is written φ 0  ( z ) = α     β  ( R ) + b  ∫ 0 R  β  ( R 1 )   W , ( 15 )

Figure US06506148-20030114-M00005

 

where W is chosen as the function 1−R1 2/R2, and the constants a and b are to be determined such that the potential over the plane z=0 is V(r)/2 for radii r ranging from 0 to R, with V(r) given by (11). Carrying out the integration in (15) gives

 

φ0(z)=αβ(R)−b{(1+z 2 /R 2)β(R)−|z|/R}.  (16)

 

In order to find the potential over the disc r<R in the plane z=0, the function φ0(z) is expanded in powers of z/R for 0<z<R, whereafter the powers zn are replaced by rnPn(cosθ), where the Pn are Legendre polynomials, and (r,θ) are symmetric spherical coordinates centered at the screen center. This procedure amounts to a continuation of the potential from the z-axis into the half ball r0, in such a manner that the Laplace equation is satisfied. The method is discussed by Morse and Feshbach (1953). The “Laplace continuation” allows calculation of the potential φ0 along the surface of the disc r0, the parts (13) and (19) contribute about equally to the electric field over a practical range of distances z. When going behind the monitor where z is negative the monopole field flips sign so that the two parts nearly cancel each other, and the resulting field is very small. Therefore, in the back of the CRT, errors due to imperfections in the theory are relatively large. Moreover our model, which pretends that the polarization charges are all located on the polarization disc, fails to account for the electric field flux that escapes from the outer regions of the back of the screen to the earth or whatever conductors happen to be present in the vincinity of the CRT. This flaw has relatively more serious consequences in the back than in front of the monitor.

 

Screen emissions in front of a CRT can be cut dramatically by using a grounded conductive transparent shield that is placed over the screen or applied as a coating. Along the lines of our model, the shield amounts to a polarization disc in front of the screen, so that the latter is now sandwiched between to grounded discs. The screen has the pulsed potential distribution V(r) of (11), but no electric flux can escape. The model may be modified by choosing the polarization disc in the back somewhat smaller than the screen disc, by a fraction that serves as a free parameter. The fraction may then be determined from a fit to measured fields, by minimizing the relative standard deviation between experiment and theory.

 

In each of the electron beams of a CRT, the beam current is a nonlinear function of the driving voltage, i.e., the voltage between cathode and control grid. Since this function is needed in the normalization procedure, it was measured for the 15″ computer monitor that has been used in the ½ Hz sensory resonance experiments and the electric field measurements. Although the beam current density j can be determined, it is easier to measure the luminance, by reading a light meter that is brought right up to the monitor screen. With the RGB values in the VB6 program taken as the same integer K, the luminance of a uniform image is proportional to the image intensity I. The luminance of a uniform image was measured for various values of K. The results were fitted with

 

I=c 1 K γ,  (20)

 

where c1 is a constant. The best fit, with 6.18% relative standard deviation, was obtained for γ=2.32.

 

Screen emissions also occur for liquid crystal displays (LCD). The pulsed electric fields may have considerable amplitude for LCDs that have their driving electrodes on opposite sides of the liquid crystal cell, for passive matrix as well as for active matrix design, such as thin film technology (TFT). For arrangements with in-plane switching (IPS) however, the driving electrodes are positioned in a single plane, so that the screen emission is very small. For arrangements other than IPS, the electric field is closely approximated by the frin

Dr. Charles Richard Drew Mural 2014 by Susan Schwerin

 

Dr. Drew can be seen on the left, rising out of the fog (symbolizing his neighborhood, Foggy Bottom, in DC where he was born). He is holding a test tube of blood that has been separated into its individual components: plasma (55%), platelets (1%) and red blood cells (44%). Next to him is a microscope with a microscopic view of each blood element in the background. The red blood cells are marked for the various blood types (A+,A-, B+,B-, O; however, in 1 drop of someone’s blood all of the red blood cells would be the same type, I have only mixed them here to exemplify that there are different types). Plasma, however, is not very different across people making it a better candidate for transfusions, plus it does not need to be refrigerated and lasts a long time.

Dr. Drew’s steps to “SUCCESS” are created by his education and training:

 

First he went to Stevens Elementary where he was received medals for swimming2 (“S” of success with silhouette of swimmer).

 

Next he went to Dunbar high school where he lettered in track (hurdles), football, baseball and basketball1(“U” of success with silhouette of hurdles, football, baseball, basketball).

 

Then he was off to Amherst college where he was captain of the track team and was the most valuable player on the baseball team, star halfback, national high hurdles champion5(“C” of success with silhouette of baseball, football and hurdles).

 

After graduating he started saving for medical school by teaching biology and chemistry and coaching football and basketball at Morgan State University in Baltimore1. During his two years at Morgan, his coaching transformed its mediocre sports teams into serious collegiate competitors1 (“C” of success with silhouette of an instructor and a coach, a football and a basketball).

 

He then went to McGill Medical School where he earned a Doctor of Medicine degree (MD) and a Master of Surgery (CM)2. He joined the Omega Psi Phi fraternity where he helped to pen their fraternity hymn, “Omega Dear”3. He was also inducted into the medical honor society Alpha Omega Alpha2. He won a neuroanatomy award2 and continued to excel competing in hurdles (“E” of success with silhouette of music notes, brain, hurdles).

 

He then went to work as a surgeon and teacher at Howard University, where they were trying to get and/or train their faculty to be competitive in their fields (“S” of success with silhouette of instructor and surgeon).

 

Dr. Drew got a Rockefeller Foundation research scholarship to get his doctorate at Columbia University where he wrote a thesis titled, ”Banked Blood”2 (“S” of success with silhouette of researcher at microscope and thesis).

  

World War II broke out. There is a world map at the bottom of the mural where the different countries are colored according to whether they were on the side of the Axis (blue-primarily Germany, Italy, Japan, and also Slovakia, Romania, Hungary, Bulgaria, Libya, Ethiopia, Somalia, Thailand, Taiwan, Korea, Irag, Finland) or the Allies (green: primarily United Kingdom, France, China, Soviet Union, United States and also Australia, New Zealand, Canada, Belgium, Brazil, Czechoslovakia, Denmark, Estonia, Greece, India, Latvia, Lithuania, The Netherlands, Norway, Poland, South Africa, Yugoslavia with light green being countries that joined the war late: United States, Mexico, many South American countries, Liberia, Turkey, Iran, Saudi Arabia, and Phillipines) or Neutral countries (gray-primarily Ireland, Portugal, Sweden, Switzerland, Spain, and also Sahara, Angola, Mozambique, Yemen, Afghanistan, Tibet, Estonia, Latvia, and Lithuania).

 

After the war started, Dr. Drew was requested to organize the Red Cross Blood for Britain program (represented by the blood transfusion line spelling out Blood Bank, which then enters the top of the Red Cross symbol in the middle of the mural), where his attention to detail and doctorate research on blood banking enabled him to effectively collect blood, separate out the plasma and ship it to wounded British soldiers (represented by the yellow plasma transfusion line leaving the Red Cross symbol and going to the soldiers in the bottom right of the mural). The plasma transfusion line makes the shape of an EKG heart beat signal before getting to the soldiers, showing that it is giving life (giving heart beats). Beneath the soldiers is an open box with open cans, this is the box they received from the Red Cross with the dried plasma and distilled water which they combined to reconstitute the plasma to give to the soldier on the battlefield. Behind the soldiers is the British Flag. After the US joined the war, Dr. Drew led the National Blood Donor Service as well (represented by the American Flag on the far right of the mural).

 

In order to meet the huge demand for plasma, Drew initiated the use of "bloodmobiles" - trucks equipped with refrigerators6.

 

Unfortunately, the irony of his work was that the Red Cross would only accept blood from white donors. (This is shown in the mural by the 5 hands at the top. The center hand is Caucasian and is the only hand, whose blood drop has a Red Cross symbol on it, even though all the blood drops look the same, no matter what color hand is holding it). Dr. Drew publicly stated that the blood from different races was no different; however the Red Cross continued to exclude black donors. They eventually began allowing black donors, but kept the blood segregated for the recipients.

 

The NAACP gave Dr. Drew the Springarn award for "the highest and noblest achievement" by an African-American "during the preceding year or years” for his blood banking accomplishments2 (The medal and ribbon are at the top of the mural, just under the hands). This award bolstered Dr. Drew into becoming more of an advocate for black rights4.

 

Dr. Drew had a personal commitment to excellence as well as an expectation of excellence of his black medical students who frequently scored among the highest in nationwide medical exams (represented by the word “EXCELLENCE” in the mural). Dr. Drew continued to teach at Howard University where he was known by his students as ‘Big Red’ because of the color of his face when he was upset4 (represented in the mural by the Howard University Bison Logo with the words “Big Red”).

 

Dr. Drew died in a car accident in 1950 at the age of 45 (represented by the car in the upper right hand corner of the mural).

 

While attending a conference in April 1939, Drew met Minnie Lenore Robbins, a professor of home economics at Spelman College in Atlanta. They married in September of that year, and had three daughters and a son (represented on the mural by the house with the family inside, just under the Red Cross).

 

Dr. Drew’s one leisure activity was gardening, especially Canna Lily flowers4, which are featured at the base of the mural under SUCCESS.

 

The hand in the upper left corner of the mural that is punching through the wall is a representation of this quote by Dr. Drew and symbolizes how his accomplishments (the blood bank) knocked a hole out of the wall:

“Whenever, however, one breaks out of this rather high-walled prison of the "Negro problem" by virtue of some worthwhile contribution, not only is he himself allowed more freedom, but part of the wall crumbles. And so it should be the aim of every student in science to knock down at least one or two bricks of that wall by virtue of his own accomplishment.”
