This is because the incompatibility of Ag relative to Cu (especially in MSS) means that the Cu/Ag ratio in primitive magmas is dependent on the degree of mantle melting and the relative proportions of solid and liquid mantle sulfide. By invoking a mostly solid rather than liquid sulfide in ...
Cld genomic neighborhoods were searched for genes known to participate in the response to reactive chlorine species: methionine sulfoxide reductases, sulfur homeostasis proteins, protein chaperones, regulatory systems, and scavenging of reactive byproducts like peroxides, aldehydes, and glyoxals [6,53,54...
Since the spectra of ozone, nitrogen dioxide, sulfur dioxide, and certain aerosols are well known, scientists can directly correlate SAGE's readings with the presence of these substances within the stratosphere. The solar occultation technique is particularly effective because the sensor is self-...
obtain from dilute waters. Routine application of36Cl to age tracing of groundwater is possible only because of the high sensitivity and much smaller sample size permitted by AMS (Elmore et al., 1979). Because anisotopic ratiois measured by mass spectrometry, the atomic ratio, atoms36Cl per ...
(0.1–1.5%). Bulk density, horizon thicknesses and stoniness affect total storage of Cl more than concentration differences. Unfortunately, these parameters make the calculation of total Cl storage capacity difficult. Total storage is usually largest in the mineral soil layer because of its greater...
Chloramphenicol (CAP) is a broad-spectrum antibacterial veterinary drug and has been extensively used for the treatment of infectious diseases in animals. However, it has been recognized that the CAP may cause many chronic diseases such as bone marrow depression, aplastic anemia and cardiovascular col...
magma degassing using H2O and CO2because the latter is extensively degassed by the time magmas reach shallow sub-volcanic or ore-forming domains. More generally, emerging views on these “trans-crustal” magmatic systems4,13,14invoke volatile release from chemically diverse arc melts over a wide ...
It is clear that the bang gap for the hydrogenated samples is smaller than the pure TpriOev2i.oIuns tDhFeTcacsaelcouflaCtli:oHn:sT. iFOro2,mit is seen that the band gap is highly reduced, which is in agreement with the above, it is demonstrated that hydrogenation treatment can ...
is higher, or if owing to the design of the burner or for other reasons the combustion causes difficulties, the Cl-waste is diluted with a conventional fuel such as natural gas, fuel oil, etc. An important requirement is essential absence of sulfur. If either Cl-waste or fuel contain ...
(C) above. The synergistic action of the combination is noted in that the silver protection afforded by any one of the additives (A) through (C), alone, or that afforded by the sulfur-containing compound, alone, can be significantly enhanced if these materials are used in combination in ...
