the effects of dietary nucleotide (nt) were evaluated on some serum biochemical parameters and acute stress responses of the catfish (pangasianodon hypophthalmus). five experimental diets including 0, 0.25, 0.5, 0.75, and 1% nt were supplied to catfish fry for 10 weeks. at the end of the experiment, fish fed the control and 1% nt diets were subjected to handling and crowding stress. the results...

We study how the average performance of a system degrades as the load nears its peak capacity. We restrict our attention to the performance measures of average sojourn time and the large deviation rates of buffer overflow probabilities. We first show that for certain queueing systems, the average sojourn time of requests depends much more weakly on the load ρ than the commonly observed 1/(1 − ρ...
