study of the spatial variability of infiltration characteristics is essential to estimating infiltration parameters on a local scale. the objectives of the present study were to scale the parameters of a philip two-term model for infiltration and survey the variability of infiltration characteristics geostatistically using wastewater in the bajgah catchment. infiltration was measured at 30 poin...

conclusion the results of the study suggest that biofeedback training may help to train stressed athletes to acquire a control over their psychophysiological processes, thus helping an athlete to perform maximally. results two way repeated measure anova was used to simultaneously compare within and between group differences. response time, concentration, heart rate variability, respiration rate...

The human proteome is rich with protein kinases, and this richness has made the kinase of crucial importance in initiating and maintaining cell behavior. Elucidating cell signaling networks and manipulating their components to understand and alter behavior require well designed inhibitors. These inhibitors are needed in culture to cause and study network perturbations, and the same compounds ca...

We evaluated the variability in the amount of protein adsorbed onto the surface of individual wells of an assortment of microtitre plates by use of procedures involving enzyme-protein conjugates. Coefficients of variation in adsorbed protein ranged from 5.2 to 29.5%. Microtitre plates show a distinct "edge effect"; wells at the edges of a plate adsorb more protein than those in the interior, wh...

We present spectroscopic observations of the peculiar emission line star Hen 3-640, the optical counterpart of the hard X-ray source A 1118-61, from 1985 to 1997. Our data confirm strong spectral variability (both on long and short time scales) of the star and the correlation between the hard X-ray flux and the Hα equivalent width. We also found a significant Hα/Hβ flux ratio variability during...

Rats were mated for two or 15 hours and variability of day-12-embryos in weight, protein content, and [3H]thymidine incorporation was compared in the long mating period (LMP) and short mating period (SMP) groups by a 2-level nested analysis of variance. Variability in day-20 fetal weight was similarly compared. In both groups day-12 embryonic weight was relatively more variable than day-20 feta...

prosite database contains a set of entries corresponding to protein families, which are used to identify the family of a protein from its sequence. although patterns and profiles are developed to be very selective, each may have false positive or negative hits. considering false positives as items that reduce the selectiveness of a pattern, then, the more selective pattern we have, a more accur...
