Although the heat bath of Nosé–Hoover thermostat consists of only one imaginary particle, simulation systems achieve realistic constant-temperature condition (canonical ensemble). Therefore, the Nosé–Hoover thermostat has been commonly used as one of the most accurate and efficient methods for constant-temperature molecular dynamics ...
This U.S. design was the heavy but highly efficient (i.e., nuclear weapon yield per unit bomb weight) 25 Mt (100 PJ) B41 nuclear bomb. [21] The Soviet Union is thought to have used multiple stages (including more than one tertiary fusion stage) in their 50 Mt (210 PJ) (100 Mt (420 PJ) in intended use) Tsar Bomba.
Energy from a nuclear explosion is initially released in several forms of penetrating radiation. When there is surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats the material to an equilibrium temperature (i.e. so that the matter is at the same temperature as the fuel powering the explosion).
The blast incited a strong international reaction over atmospheric thermonuclear testing. [ 5 ] The Bravo Crater is located at 11°41′50″N 165°16′19″E / 11.69722°N 165.27194°E / 11.69722; 165.
The Mark 39 design was a thermonuclear bomb and had a yield of 3.8 megatons. [1] It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the ...

Changing the temperature by 7 to 10 degrees for eight hours a day, in winter and summer, can save about 10% a year on heating and cooling, the department said. This step to save money and energy ...
Diagram of a radioisotope heater unit. A radioisotope heater unit (RHU) is a small device that provides heat through radioactive decay. [1] They are similar to tiny radioisotope thermoelectric generators (RTG) and normally provide about one watt of heat each, derived from the decay of a few grams of plutonium-238—although other radioactive isotopes could be used.
