In thermodynamics, themelting pointdefines a condition where the solid and liquid can exist in equilibrium. Adding heat will convert the solid into a liquid with no temperature change. The melting point of a substance depends on pressure and is usually specified at standard pressure. When considere...
Let us now determine the specific heat of the unsymmetrical phase, on a line of transitions of the first kind but again near the critical point. At points on this line, two different phases (symmetrical and unsymmetrical) are in equilibrium with each other. The value of the parameter η in...
Because the deaminase domain of APOBEC1 lacks both a nuclear localization signal and a nuclear export signal, the engineered enzyme system should be localized to the cytoplasm, where it is likely to encounter the target mRNA. However, it remains to be determined whether small amounts of the ...
A heat exchanger (1), especially for a pressurized water cooled nuclear reactor (PWR), has a cylindrical outer shell (2) with its axis (8) vertical when in service, and a bundle of tubes fixed to holes in a tube plate (4) connected to a water chamber (5) with openings in its ...
The ignition or fire point is lowest temperature at which rapid combustion of a fuel will take place in air. It is the temperature at which all the fuel has been sufficiently heated and vaporized to continue to burn for at least 5 s. For #2 oil and Bioheat, ignition point is over 500...
Atomically thin two-dimensional (2D) materials are ideal host systems for quantum defects as they offer easier characterisation, manipulation and read-out of defect states as compared to bulk defects. Here we introduce the Quantum Point Defect (QPOD) database with more than 1900 defect systems com...
The more time I spend writing about climate change — and air pollution, and freeways, and heat, and nuclear power, and lithium-ion batteries — the more I think human beings, myself included, can be pretty terrible at evaluating risk and reward. ...
EXPERIMENTAL INVESTIGATION OF HEAT REJECTION PROBLEMS IN NUCLEAR SPACE POWERPLANTS. VOLUME 3. SPACE POWERPLANT STARTUP AND TRANSIENT OPERATION SIMULATION. ... Experiments were conducted on a nuclear Rankine-cycle space power-plant simulator using water as the working fluid to determine suitable means ...
Since weaving presumes adding auxiliary model elements in both, base model and advice, we distinguish two sides of a weaver, base model side and advice model side. In this section, we first revisit the types of JPs defined in Ref. [25] and introduce new types of JP-s that provide more...
Magnetic reconnection is a key mechanism involved in solar eruptions and is also a prime possibility to heat the low corona to millions of degrees. Here, we present ultra-high-resolution extreme ultraviolet observations of persistent null-point reconnect
