The absorption of pulsed microwave irradiations by a material causes a sudden rise of its temperature and the generation of an acoustic wave by thermoelastic effect.
This often results in thermal degradation or even decomposition where the action of heat or elevated temperatures on a material causes a loss of physical, mechanical, or electrical properties or at worse generate harmful gases [32].
Formation and ultrasonic removal of fouling particle structures in a porous material (caused by the flow of a liquid with small through the material) was studied with natural sandstone.
Pepys' diary is a window onto the physical reality of life written at the exact moment when Newton was showing that everything in the universe has a material cause and effect that human beings can understand.
A cause in this sense has been traditionally called a material cause, although Aristotle himself did not use this label.
In general, without pretending to include each philosophical position with their nuances, all these postures reduce activity- or the cause of activity- to a material cause.
Indian thought tended to assume that the cause of a thing's being or existence must be a kind of material or substratum (a "material cause") which is then shaped or formed to make it an existent being of a particular sort an existent elephant, for example, or an existent earth or water atom.
Similarly, if we think that there are mathematical or geometrical abstractions, for instance a triangle existing as an object of thought independent of any material realization, then the triangle will trivially lack a material cause.[17] Still, these significant exceptions aside, Aristotle expects the vast majority of explanations to conform to his four-causal schema.
As the unusually weak economic recovery continues, you've at least got to wonder if future studies of what ails us will include our aging population as a material cause.
Whatever the detailed mechanism, it now seems clear that ZSCAN4 is a material cause for the correction of aneuploidy: the mechanism operates independent of the vehicle of ZSCAN4 delivery to yield a dramatic increase in cells with normal karyotype.
