Heat Rays Of Great Wave Length

Dispersion of Long Wave-Length X-Rays in Platinum and Calcite.

trons still in atoms but capable of going over to adjacent ions-becomes small. If we imagine a condition, at some low temperature, in which X' becomes zero, the distinction between free electrons and associated electrons will be extinguished. In such a case the electrons, if once started in a given direction by an applied e.m.f., might go on indefinitely in that direction, there being nothing t...

The Great 2006 Heat Wave over California and Nevada: Signal of an Increasing Trend

Most of the great California–Nevada heat waves can be classified into primarily daytime or nighttime events depending on whether atmospheric conditions are dry or humid. A rash of nighttime-accentuated events in the last decade was punctuated by an unusually intense case in July 2006, which was the largest heat wave on record (1948–2006). Generally, there is a positive trend in heat wave activi...

Heat Transfer Analysis of Nanofluid in a Sine Wave Plate Heat Exchanger

Heat transfer is one of the most critical processes in the industry, and by increasing the efficiency of the heat exchanger, energy consumption of systems will be reduced. Very tiny particles in nanoscale dimensions, when uniformly dispersed and stably suspended in the base fluid, efficiently improve the thermal properties of the base fluid. With the help of nanofluids, the heat transfer rate i...

Sensitization to Heat by X-rays

1. Paramecium caudatum is sensitized to heat by sublethal dosages of x-rays. Thus if paramecia are irradiated, then exposed to a sublethal dosage of heat they are killed, but if the same heat exposure precedes the same dosage of radiations, they are not. 2. Sensitivity to both heat and x-rays is much greater in paramecia from the log growth phase than in those from the stationary phase of a cul...
