Previous ENDOR studies on reaction centers from Rhodopseudomonas sphaeroides have shown the presence of two hydrogen-bonded protons associated with the primary, ubiquinone, acceptor Q(A). These protons exchange with deuterons from solvent (2)H(2)O. The effect of this deuterium substitution on the charge-recombination kinetics (BChl)(2) (+)Q(A) (-) --> (BChl)(2)Q(A) has been studied with a sensi...

In this paper, we present a transfer function representation of a general one-dimensional combustor. The input of the transfer function is a heat rate perturbation of a burner and the output is a flow velocity perturbation at the burner. This paper considers a general combustor model composed of multiple cans with different cross sectional areas, along with a non-zero flow rate. Keywords—Thermo...

Network exchange is now widely used. However, it still cannot avoid the problems evolving from network exchange. For example. A buyer may not receive the order even if he/she makes the payment. For another example, the seller possibly get nothing even when the merchandise is sent. Some studies about the fair exchange have proposed protocols for the design of efficiency and exploited the signatu...

The sampling method used purposive with criteria set by researcher so that 24 was in this study. Management data research using multiple linear regression. results indicate share owne...

We compare the effect of buffers on the catalysis by bovine carbonic anhydrase, human carbonic anhydrase C (HCA 0, and human carbonic anhydrase B (HCA B) of two types of ‘“0 exchange. Type I, resulting from the hydrationdehydration reaction, is the exchange of IsO between CO, and water. Type II is the exchange of IsO between ‘*Ccontaining and ‘“C-containing species of COZ. Imidazole, 2,4-lutidi...
