Benthic processes play a major role in aquatic ecosystems. Detailed models of these processes exist but are costly in terms of calculation time. A simplified surrogate algorithm is derived to simplify benthic flux calculation in river system models. FullText for HTML: https://doi.org/10.1051/limn...
You are mixing strong bases with a strong acid, so they will react. The reaction is called neutralization. Whatever is left after the reaction, will be responsible for the final pH. Logged ChemBuddy chemical calculators - stoichiometry, pH, concentration, buffer preparation, titrations.infoPrint...
The present invention provides algorithm-based molecular assays that involve measurement of expression levels of genes from a biological sample obtained from a kidney cancer patient. The present invention also provides methods of obtaining a quantitative score for a patient with kidney cancer based on ...
