Eastern State Penitentiary was once the most famous and expensive prison in the world, but stands today in ruin, a haunting world of crumbling cellblocks and empty guard towers. Known for its grand architecture and strict discipline, this was the world’s first true “penitentiary,” a prison designed to inspire penitence, or true regret, in the hearts of convicts. Its vaulted, sky-lit cells once held many of America’s most notorious criminals, including bank robber “Slick Willie” Sutton and Al Capone.

The Apollo Fuel Cell was designed to convert cryogenic oxygen (O2) and hydrogen (H2) into electrical power. A vitally important by-product of this chemical reaction was the production of water (H2O) which was used by the astronauts during their mission. A complement of three 28-volt fuel cells provided all the onboard electrical power to the Apollo Command and Service Module (the Lunar Excursion Module was battery powered). Each fuel cell was rated at 1.5kW, with a maximum power of 2.2kW for brief periods. Each fuel cell consisted of 31 cells connected in scries (each producing one volt) and weighed 245 pounds. Each fuel cell had its own hydrogen and oxygen compartment and two electrodes (conductors). The heat produced by the chemical reaction (mixing H2 with O2) was used to maintain the gases at a reactive temperature (385 F) while excess heat was vented into space. The three power cells operated in parallel; although a single power plant was enough to ensure safe return. Fuel cells were first tested during the Gemini program and are still used today, in modified form, aboard the Space Shuttle.
Flotation Cells on display at the The Jack Koza Memorial Park in the Town of Cobalt Coleman Township in the District of Timiskaming Northeastern Ontario Canada
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. ... Flotation has now become the most widely used process for extracting many minerals from their ores.
Cancer cells can become mobile and travel in the bloodstream to invade other organs. From a physics perspective, there are clues pointing to cancer as a phenomenon influenced by forces and fields – not one that is purely ruled by genetic instructions. It is fascinating, for example, that the Young’s modulus of cells changes as cancer progresses, sometimes dramatically, while the stiffness of the tissue that cells touch can affect their gene expression – a process known as mechano-transduction.
Differential blood cell counter is an ideal electrical equipment to escort for counting of different blood cell. It also assists in other laboratory procedures with the integral facility of timer & stop watch. It has in-built timer and stop watch facility for other laboratory procedures too. It has tack tile keys for reliability and durability. It gives percentage & individual count at any stage of counting procedure. - www.atcomaart.com/pd/53554955526553706968/blood-cells-cou...
The hot cell allows researchers to safely work with highly radioactive materials by blocking the radiation. Its walls are made of high density concrete, three feet thick, with equally thick windows of leaded glass. Robotic arms dating to 1958 allow Assistant Reactor Manager and retiree Phil Simpson to manipulate a radioactive sample the size of a thick nickel. He is in the process of welding six platinum wires coated in white zirconia onto the sample for experiments. The experiments take place in the Irradiated Material Laboratory next door, where the sample is exposed to high temperatures and mechanical stress to simulate conditions inside a nuclear reactor. Assistant Research Scientist Yugo Ashida, who runs experiments in the Irradiated Material Laboratory, looks on.

This time-lapse video shows a vascular smooth muscle cell from a human blood vessel engulfing a dying neighbour. Blue flashes show the rise and fall of calcium levels, showing the importance of calcium in this process. This improves our understanding of how smooth muscle cells help to clear dead cells in diseased blood vessels.

Kupffer cells or Browicz-Kupffer cells are specialized macrophages located in the liver that form part of the reticuloendothelial system. The cells were first observed by Karl Wilhelm von Kupffer in 1876. The scientist called them "sternzellen" (star cells or stellate cells) but thought falsely that they were an integral part of the endothelium of the liver blood vessels and that they originated from it. In 1898, after several years of research, Tadeusz Browicz identified them correctly as macrophages.
Their development begins in the bone marrow with the genesis of promonocytes and monoblasts into monocytes and then on to peripheral blood monocytes completing their differentiation into Kupffer cells.
The primary function of Kupffer cells is to recycle old red blood cells that no longer are functional. The red blood cell is broken down by phagocytic action and the hemoglobin molecule is split. The globin chains are reutilized while the iron containing portion or heme is further broken down into iron which is reutilized and bilirubin, which is conjugated with glucuronic acid within hepatocytes and secreted into the bile.
Helmy et al. identified a receptor present in Kupffer cells, the complement receptor of the immunoglobulin family (CRIg). Mice without CRIg could not clear complement system-coated pathogens. CRIg is conserved in mice and humans and is a critical component of the innate immune system - Cell 124, 915 (2006).

Training Safeguards Inspectors: Hot Cell and Glovebox Training in Georgia
Most hot cells and gloveboxes in the world are contaminated with nuclear materials which makes safe entry extremely difficult. The only way to see into most hot cells is through a small lead glass window (pictured) that requires inspectors to use mirrors. The hot cells at the Andronikashvili Institute of Physics were only used for a short time and handled radioactive isotopes with a short half-life. Therefore, the hot cells are not contaminated and are safe to enter.

The "teens don't need a cell phone until they're driving or moved out" is an interesting idea, and I understand where it's coming from. Kidssurvived for years without cell phones, and they become sort of a social crutch... it's easy to become addicted to texting, which isn't best for the phone bill OR social interaction with peers. I am, however, a firm beliver in the expression "everything in moderation and nothing in excess.I'm not so uptight as to deny my child a cell phone until age sixteen, provided he/she can handle the responsibility (which includes keeping track of it, taking good care of it, and making sure they do not go over their minutes or texts each month). As long as I have that trust in each of my children, there is no need to deny them what has almost become a staple in today's teenage society. If they mess up, then they deal with the consequences: they pay for each text or minute they go over their limit, and Mom and Dad will buy them a new phone once every two years when the contract expires... if they ruin their phone before then, they pay for a new one themselves or they go without.My husband and I do set a 500 text a month limit on our kids' phones as long as we're the ones footing the bill... and believe me, that's not a popular decision among my kids, but they deal. The reason? First of all, money, but second of all, we don't want our kids to have their noses buried in their phones all the time. My daughter's friend sends over 10,000 texts a month. 10,000! That's ridiculous. We just don't want our kids to learn to place too much importence on their phone. Above all, it is just a THING, after all
