High environmental heat and physical exertion combine to limit oxygen delivery to the heart muscle, raising ischemic risks in ...

Natural circulation relies on buoyancy forces arising from density differences in a fluid heated and cooled at distinct regions of a closed loop. This passive mechanism underpins safety and efficiency ...

Hydrothermal circulation within the oceanic crust constitutes a fundamental mechanism by which the Earth dissipates internal heat and exchanges chemical constituents with the ocean. Seawater ...

Researchers at St. Petersburg State Technical University “leti” have developed a compact, fully domestic thermal imaging system that can monitor blood flow during the surgical removal of tumors. The ...
