/ SUl\'lMARY We studied the interaction of Bis~diethylaminosilane (SiH2[N(C1HShh. BDEAS) with a hydroxylized Si (001) surface for Si01 thin-film growth using density functional theory (DFf). BDEA5 was adsorbed on the 5i surface and reacted with the H atom of hydroxyl (-OH) to produce the di-ethylaminosilane (-SiHl[N(C2HShl. DEAS) group and di-ethylamine (NH(C2HSh. DEA). Then. DEAS was able to r...

Ammonia (NH3) emissions resulting from the field application of livestock slurry has both negative human health and environmental impacts. However, decreasing exposed surface area (ESA) upon can reduce NH3 volatilization by limiting its atmospheric exposure. In present study, three strategies for depositing within a growing crop were studied, including: 1. standard trailing hoses (SAhose), 2. s...

In the present experiments we studied exclusive and overlapping cortical representational areas of the vibrissae in layer IV cells, across the entire barrel subfield of the rat somatosensory cortex, looking for evidences that would challenge the present assumptions of homogeneity and symmetry among cortical columns in this sensorial system. Our main findings were that in layer IV of the rat bar...
