The optimization problem of heat engines is formulated with the aid of the heat accumulation function at a very general level. As an example, the authors studied a heat engine process where the heat input and output changes are limited by the finite heat capacity of the combustion air. They ...
Heat engine which uses solar energy has an area which receives the solar radiation and uses it without it being dissipated to the surroundings whether by radiation or conduction. This area forms a black body by being covered with some reasonably economic substance such as minerals, metals or even...
The Effect of Wall Heat Loss on the Flow Fields in a Pulse-Detonation Wave Engine The present study addresses the influence of convective heat losses on the flow field and performance of pulse detonation engines (PDE). We investigate the simplest PDE configuration of a straight detonation tube ...

The experiments indicate that the novel rotating electromagnetic heat engine not only has the merits of high efficiency, high temperature ascending grads, but also has effects of magnetization and softening on the water medium. This kind of novel heat engine has a wide application prospect. 展开 ...
Finally, if a matching version of Apache is found, the “reporting” function security_note is used to report non-critical information back to the Nessus engine. If the script is checking for more severe vulnerabilities, securityjwarning or securityjiole can been used. 1 if(description) { 2...

Motile cilia are ultrastructurally complex cell organelles with the ability to actively move. The highly conserved central apparatus of motile 9 × 2 + 2 cilia is composed of two microtubules and several large microtubule-bound projections, i
still documents the support has experimental, of course (https://nodejs.org/dist/latest-v14.x/docs/api/esm.html#esm_experimental_top_level_await). I'm not sure why it is still marked as experimental unless they are waiting for it to enter either Stage 4 or it become part of the ...
Aristotle considered the heart to be the body's furnace, radiating energy in the form of heat14. Given the astounding energetic cost of cardiac function, this concept is not so far from the truth. Humans produce and consume roughly their body weight in ATP (about 65 kg) every single day15...
