Carbonic anhydrases (CAs, EC 4.2.1.1) are metalloenzymes which use CO2 as substrate, catalysing its interconversion to bicarbonate and a proton.In humans 15 CAs are expressed, 12 of which are catalytically active: the read more cytosolic CA I-III, VII, XIII, the membrane-bound CA IV, the mitochondrial CA VA and VB, the secreted CA VI, and the trans
In geodesy and geophysics, many large-scale over-determined linear equations need to be solved which are often ill-conditioned.When the conjugate gradient method is used, their ill-conditioning effects to the solutions must be overcome, which is studied in this paper.Through the regularization ideas, the conjugate gradient method is improved, and t
Abstract Stingless bees are a diverse group with a relevant role in pollinating native species.Its diet is rich luau thank you cards in carbohydrates and proteins, by collecting pollen and nectar supplies the development of its offspring.Fermentation of these products is associated with microorganisms in the colony.However, the composition of micro
