The kinetics of diffusion-controlled single-species annihilation, A + A → 0, when each particle has the same diffusion coefficient is now well understood [1]. For spatial dimension d > 2, the kinetics may be accounted for by the rate equation which predicts that the density decays as t−1 in the long-time limit. For d ≤ 2, various phenomenological approaches predict that the density decays as t−...

It is known that surface structural relaxation takes place more rapidly than bulk structural relaxation, especially in the presence of water vapor. The surface structural relaxation kinetics of the silica glass fiber and plates was compared at 950 C and the surface structural relaxation kinetics of silica glass fiber was found to be faster than that of the silica glass plate, even though the co...

Michaelis-Menten equation is a basic equation of enzyme kinetics and gives an acceptable approximation of real chemical reaction processes. Analyzing the derivation of this equation yields the fact that its good performance of approximating real reaction processes is due to MichaelisMenten curve (15). This curve is derived from Quasi-Steady-State Assumption(QSSA), which has been proved always t...

The fractal kinetics curve derived by Savageau is analysed to show that its parameters are not uniquely determined given four appropriately situated data points. Comparison is made with an alternate fractal Michaelis-Menten equation derived by Lopez-Quintela and Casado.

The nutritive values of non-processed and processed pistachio peel with Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis. An in vitro digestibility study was done to determine digestibility coefficients of dry matter (DM), organic matter (OM). Digestible organic matter in the dry matter (DOMD) to estimate the metabolizable energy (ME)...

In this study, the nutritive values of treated Walnut hull by Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis.In vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate the metabolizable energy (ME) content oftreat...

The kinetics of Mn(VII) oxidation of lysine in moderately sulfuric acid solutions was studiedspectrophotometrically in the presence and absence of Mn(II) as catalyst. The reaction was arrangedto be under pseudo first-order condition with respect to Mn(VII). The results showed that the pseudofirst-order rate constant increases with increasing [H2SO4], [(Mn)II], and [lysine]. The dependence ofthe...

The kinetics of iodination of the phenol and substituted phenols using pyridiniumiodochloride in methanol has been studied under varying conditions. The rates show first orderkinetics each in pyridinium iodochloride and phenols. The rates of reactions are measured atdifferent temperature and activation parameters for all phenols computed. Hammett plot is foundto be valid and the corrletion betw...
