The influence of pressure could be tested. The relation of ionisation by gamma rays for different gases was measured, but it was found not to be the same for rays of different energy.doi:10.1016/S0031-8914(38)80194-4J. ClayM. KwieserElsevier B.V.Physica...
THE ionization by radioactive gamma and cosmic rays in different gases has been investigated by V. Masuchsince 1932 and by me since 1936. For all measurements we used the same Kolhrster apparatus, the zero of which was separately determined at a depth of 406 m. in the Berlepsch salt ...
For most common gases the mean free path (i.e., the average distance between collisions) is in the range of 10−4 to 10−5 cm. Often, electron collisions with gas molecules result in electron attachment to the molecule, which forms a negative ion. The probability of attachment to a ...
For decades we used to treat heat as a low-value, unwanted energy form, an indicator of inefficiencies. Diesel engine engineers, on the other hand, are struggling to use every Joule of heat available in the exhaust gases to keep the catalysts active, especially under city driving conditions....
All containers should be checked for leaks prior to adding radioactive gas. If the counting room or detector shield atmosphere becomes contaminated with radioactive gas, these areas should be vented to remove the gases before counting any standards. 4. Radioactive noble gases diffuse throu...
The values of static breakdown voltage for different values of exposed dose rates of gamma radiation were estimated on the basis of the experimental breakdown voltage data using a second order polynomial fit. 展开 关键词: Theoretical or Mathematical, Experimental/ afterglows electric breakdown gamma-...

(γ-glutamyl)lysine formation, and so allow the formation of NAC polymers. The formation of NAC polymers is important because the aggregated molecule is more toxic than the monomeric form (El-Agnaf et al., 1998; Forloni et al., 2000). Thus, TGases may contribute to the pathology of ...
