The aim of this study was to evaluate the effect of levels of different vitamin E and selenium in tris extender on spermatozoa characteristics of Arabic ram. Semen collection was performed from 8 Arabic rams and mixed together. The mixed semen was divided in to 9 parts and after dilution with tris, different levels of selenium and vitamin E were added. This experiment was carried out in 3×...
The concentration of an inhibitor that decreases the rate of an enzyme-catalysed reaction by 50%, symbolized i(0.5), is often used in pharmacological studies to characterize inhibitors. It can be estimated from the common inhibition plots used in biochemistry by means of the fact that the extrapolated inhibitor concentration at which the rate becomes infinite is equal to -i(0.5). This method is...
The distributions obtained by left-truncating at k a mixed Poisson distribution, kT-MP, those obtained by mixing previously left-truncated Poisson distributions, M-kTP; and those obtained by left-truncating at k a mixture of previously left-truncated Poisson distributions, kT-M-iTP, are characterized by means of their probability generating function. The kT-MP models are useful because they apr...
In the literature, there exist strong results on the qualitative dynamical properties of chemical reaction networks (also called kinetic systems) governed by the mass action law and having zero deficiency. However, it is known that different network structures with different deficiencies may correspond to the same kinetic differential equations. In this paper, an optimization-based approach is ...
