Femtosecond spectroscopy was used in combination with site-directed mutagenesis to study the influence of tyrosine M210 (YM210) on the primary electron transfer in the reaction center of Rhodobacter sphaeroides. The exchange of YM210 to phenylalanine caused the time constant of primary electron transfer to increase from 3.5 +/- 0.4 ps to 16 +/- 6 ps while the exchange to leucine increased the t...

Acetate assimilation in C. reinhardtii leads to bicarbonate and CO2 aq formation in heterotrophic growth condition. Bicarbonate and CO2 aq thus formed under this condition remain in equilibrium with the action of carbonic anhydrases. Carbonic anhydrase catalyzes reversible hydration of carbon dioxide and dehydration of bicarbonate. In this article we report that the rapid exchange catalyzed by ...

Business development encourages companies to grow into multinational whose activities are not only centered on one country. In transactions carried out by companies, it is possible for manipulate transfer prices (transfer pricing). The practice of pricing with the hope reducing tax burden and also minimizing amount that must be paid State. purpose this study determine effect burden, bonus mecha...

output characteristics of fuel cells are affected by a large number of parameters such as geometry, dimensions, construction materials and conditions of supplying fluids. in this paper a mathematical model followed by a two-dimensional numerical approach has been presented to study the fuel cell parametrically. effect of oxygen concentration at gas diffusion layer entrance, temperature and pres...
