Kuiper belt: ...is a region of the Solar System beyond the planets extending from the orbit of Neptune (at 30 AU [Astronomical units]) to approximately 55 AU from the Sun. It is similar to the asteroid belt, although it is far larger—20 times as wide and 20–200 times as massive. Like the asteroid belt, it consists mainly of small bodies, or remnants from the Solar System's formation. While the asteroid belt is composed primarily of rock and metal, the Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water. It is home to at least three dwarf planets – Pluto, Haumea and Makemake.
Scattered disc: ...is a distant region of the Solar System that is sparsely populated by icy minor planets, a subset of the broader family of trans-Neptunian objects. The scattered disc objects have orbital eccentricities ranging as high as 0.8, inclinations as high as 40°, and perihelia greater than 30 astronomical units. These extreme orbits are believed to be the result of gravitational "scattering" by the gas giants, and the objects continue to be subject to perturbation by the planet Neptune. While the nearest distance to the Sun approached by scattered objects is about 30–35 AU, their orbits can extend well beyond 100 AU. This makes scattered objects "among the most distant and cold objects in the Solar System". The innermost portion of the scattered disc overlaps with a torus-shaped region of orbiting objects known as the Kuiper belt, but its outer limits reach much farther away from the Sun and farther above and below the ecliptic than the belt proper.
Because of its unstable nature, astronomers now consider the scattered disc to be the place of origin for most periodic comets observed in the Solar System...
Formation of the Kuiper belt and Scattered disc?: The scattered disc is still poorly understood: no model of the formation of the Kuiper belt and the scattered disc has yet been proposed that explains all their observed properties.
According to contemporary models, the scattered disc formed when Kuiper belt objects (KBOs) were "scattered" into eccentric and inclined orbits by gravitational interaction with Neptune and the other outer planets. The amount of time for this process to occur remains uncertain. One hypothesis estimates a period equal to the entire age of the Solar System; a second posits that the scattering took place relatively quickly, during Neptune's early migration epoch.
Models for a continuous formation throughout the age of the Solar System illustrate that at weak resonances within the Kuiper belt (such as 5:7 or 8:1), or at the boundaries of stronger resonances, objects can develop weak orbital instabilities over millions of years. The 4:7 resonance in particular has large instability. KBOs can also be shifted into unstable orbits by close passage of massive objects, or through collisions. Over time, the scattered disc would gradually form from these isolated events...Modern theories indicate that neither Uranus nor Neptune could have formed in situ beyond Saturn, as too little primordial matter existed at that range to produce objects of such high mass. Instead, these planets, and Saturn, may have formed closer to Jupiter, but were flung outwards during the early evolution of the Solar System, perhaps through exchanges of angular momentum with scattered objects. Once the orbits of Jupiter and Saturn shifted to a 2:1 resonance (two Jupiter orbits for each orbit of Saturn), their combined gravitational pull disrupted the orbits of Uranus and Neptune, sending Neptune into the temporary "chaos" of the proto-Kuiper belt. As Neptune traveled outward, it scattered many trans-Neptunian objects into higher and more eccentric orbits... - enWikipedia

At approximately 4:50 p.m. on January 19, 2017, six astronaut-like crewmembers entered a geodesic dome located 8,200 feet above sea level on Mauna Loa on the island of Hawaiʻi, which will serve as their home for the next eight months.

On Oct. 14-16, 2013, Argonne National Laboratory and the University of Chicago organized the 2013 edition of the “Materials Modeling and Simulations for Nuclear Fuels” (MMSNF) workshop series in downtown Chicago.
Poster sessions provided an opportunity for more interactive, in-depth discussions and were well attended by workshop participants.

SGMC EMTs participated in a drunk driving awareness demonstration at Valdosta High School. Students Against Drunk Driving and first responders reenacted a car crash in which drunk drivers were arrested and multiple injuries and causalities resulted. Everyone did a great job at showing students the importance of safe driving during this prom season. **Remember that this was a simulation, no one was actually injured during this demonstration.
College of DuPage health Sciences students participated in a multi-discipline simulation involving students currently in the College's EMT, Nursing, CT, Surgical Tech, Nuclear Medicine and Respiratory Care programs. The scenario, played out by a combination of actors and mannequins involved a domestic situation in which a husband shot his wife and two children leaped from a two-story window to avoid a fire.
Molecular dynamics simulation of bacterial toxin alpha hemolysin embedded in a lipid membrane. Alpha hemolysin is toxin secreted by Staphylococcus aureus and it can cause lysis (breakdown) of red blood cells. Alpha hemolysin and its modfications have also been suggested to be useful in developing nanosensors, in drug delivery and even in DNA sequencing. We have studied how water interacts with the alpha hemolysin pore and how the behavior of water and small molecules can be controlled inside the pore using different driving forces.
What you see here: The protein is embedded in a POPC bilayer. This movie shows a side view with the lipids visible. The simulation is in explicit water but for clarity, we track the behavior of a few water molecules and how they move in the system and inside the pore. The simulation was 130 ns.
Note: MD simulations of pore containing system (membrane proteins and nanotubes) require special attention on the simulation protocol. See Ref. [2]

Epidural Anaesthesia simulation model. ESA prize 2016. The complex skills involved with administering epidurals, such as locating optimal insertion point and needle angle, can only be learned by practice. However it can be dangerous for novice anaesthetists to practice their first epidural procedure on real patients. This simulator provides a training scenario whereby novice anaesthetists can practice needle insertions and visualise bony structures.
I wish I had been smart enough to keep the original skeletor simulation in white when I made them 6 years ago.

The DB Class V90 (after 1968 the DB Class 290) locomotive is a German diesel-hydraulic locomotive for shunting and freight hauling.
Class 294
From 1995, large numbers of locomotives of the class were fitted a different type of radio remote produced by Krauss-Maffei (KM)
The remote device is carried by remote train driver (German:Lokrangierführe LRF ) in a so called "Belly Box" (see Remote control locomotive for details) and operated in a manner similar to that of a toy car or model aircraft remote control.
This type of control is used in shunting operations and was previously used with smaller shunting locomotives such as the DB Class V 60 and DB Class Köf III (DB class 331 to 335)
The rebuilt locomotives of the 290 series form Class 294

Can democrats and republicans work together on immigration reform? West Point cadets gave it a try during the Congressional Simulation Exercise on April 4. The daylong exercise was designed to give about 150 West Point cadets in the SS202 and SS252 (American Politics) courses a hands-on, real-world simulation of government in action. Participants absorbed the role of legislators, journalist, lobbyists and presidential advisers in a daylong capstone exercise to see who can best use political capital to create the best outcome for their group.
