Nitrogen assimilation plays a vital role in plant metabolism. Assimilation of nitrate, the primary source of nitrogen in soil, is linked to the generation of the redox signal nitric oxide (NO). An important mechanism by which NO regulates plant development and stress responses is through S-nitrosylation, that is, covalent attachment of NO to cysteine residues to form S-nitrosothiols (SNO). Desp...
BACKGROUND Entry of Severe Acute Respiratory Syndrome coronavirus (SARS-CoV) and its envelope fusion with host cell membrane are controlled by a series of complex molecular mechanisms, largely dependent on the viral envelope glycoprotein Spike (S). There are still many unknowns on the implication of cellular factors that regulate the entry process. METHODOLOGY/PRINCIPAL FINDINGS We performed ...
In this paper, a plate counter-flow dew-point evaporative cooling system was designed with nanoporous membrane covered on the surface of wet channel for enhancement heat and mass transfer. First, operating principle device theoretical analysis evaporation were discussed in detail. Then, impacts several parameters performance, mainly including inlet air temperature, humidity, velocity, effect ut...
