摘要:Abstract(#br)Clinical evaluation and MR imaging of microangiopathy associated with hypertension is limited. We describe a case that illustrates sensitivity of MRI at 8 Tesla for imaging of microvasculature, iron, calcium deposits and silent white matter lesions (WML). A 60-year-o...

摘要:Since the days of Kirchhoff, blackbody radiation has been considered to be a universal process, independent of the nature and shape of the emitter. Nonetheless, in promoting this concept, Kirchhoff did require, at the minimum, thermal equilibrium with an enclosure. Recently, the ...

摘要:Recently, gedanken experiments have been proposed in order to examine the validity of Kirchhoff's Law of Thermal Emission (P.-M. Robitaille, Further Insight Relative to Cavity Radiation: A Thought Experiment Refuting Kirchhoff's Law, Prog. Phys., 2014, v. 10, no. 1, 38-40; P.-M. ...

摘要:Kirchhoff's law of thermal emission asserts that, given sufficient dimensions to neglect diffraction, the radiation contained within arbitrary cavities must always be black, or normal, dependent only upon the frequency of observation and the temperature, while independent of the ...

摘要:Application of the virial theorem, when combined with results from the kinetic theory of gases, has been linked to gravitational collapse when the mass of the resulting assembly is greater than the Jeans mass, MJ. While the arguments appear straightforward, the incorpo...

摘要:In equilibrium thermodynamics systems can be described in terms of properties which are either (1) intensive, (2) extensive, or (3) neither intensive nor extensive. While they can vary with spatial location in nonequilibrium systems, intensive properties are homogenous functions ...
