The high-speed generators offer superior power-to-volume ratio and highly compact structure comparing with their lower speed counterparts. These advantages make high-speed machines eligible for distributed generating application with microturbine that one of the distributed power generation that produced electric in the remote and disastrous zones where grid power is unavailable. To achieve hig...

During batch growth of Lactococcus lactis subsp. lactis NCDO 2118 on various sugars, the shift from homolactic to mixed-acid metabolism was directly dependent on the sugar consumption rate. This orientation of pyruvate metabolism was related to the flux-controlling activity of glyceraldehyde-3-phosphate dehydrogenase under conditions of high glycolytic flux on glucose due to the NADH/NAD+ ratio...

The flux ratio for hexokinase type II from rat muscle, i.e. the rate of conversion of glucose 6-phosphate molecules into ATP molecules divided by the simultaneous rate of conversion of glucose 6-phosphate molecules into glucose molecules, increases with the MgATP concentration but is independent of the glucose concentration. This behaviour requires that glucose must bind before MgATP when the r...

The present paper deals with fully developed one dimensional Bingham plastic flow of blood through a small artery having multiple stenoses and post-stenotic dilatation. We have determined the resistanceto flow -ratio for yield stresses 0, .02, .04 n/m, blood viscosities 0.00345, 0.004, 0.00455 Pa.s and fluxes 1, 10, 100. The resistanceto flow moves nearer to unity as yield stress increases and ...

The permeability of frog skin under the influence of urea hyperosmolarity has been studied. Flux ratio asymmetry has been demonstrated again for tracer mannitol. The inhibitors DNP, CN(-), and ouabain have been used to eliminate active sodium transport and it was found that urea hyperosmolarity produces asymmetrical mannitol fluxes on frog skins having no short-circuit current. These findings s...

Abstract: For the heat conduction on a bounded domain with boundary degeneracy, though its diffusion coefficient vanishes on the boundary, it is still possible that the heat flux may transfer across the boundary. A known result shows that the key role is the ratio of the diffusion coefficient near the boundary. If this ratio is large enough, the heat flux transference has not any relation to th...

In this paper it is shown th a t such behaviour may be simply modelled based on the assumption of only single occupancy of the channel. W ith use of linear flux equations the calculated flux ratio is as measured. The additional assumption of single occupancy of the channel results in the calculated values of and J qut both being multiplied by the same factor, 1 —P ,where P is the probability th...
