a new model based on a combination of the polymeric multigrain and multilayer models has been developed to predict the polymerization rate, particle growth, morphology, effective parameters on broadening of the molecular weight distribution, number and weight average of the molecular weight, isotacticity index and bulk density of polymer. mathematical correlations and the kinetics used in this ...

Kinetic investigations on Pd(II) catalyzed oxidation of D-ribose and D-arabinose by acidic solution of chloramine-T in the presence of mercuric acetate, as a scavenger have been made in the temperature range of 30°-45°C. The rate shows first order kinetics in case of chloramine-T and order of reaction is zero and one with respect to substrate and Pd(II) respectively. Increase in [Cl] showed pos...

An attempt has been made in this paper to investigate the effect of particle size distribution on coal flotation kinetics. The effect of particle size (Ps) on kinetics constant (k) and maximum theoretical flotation recovery (RI) was investigated while other operational parameters were kept constant. The relationship between flotation kinetics constant and theoretical flotation recovery with par...

In this study, after investigation of cytotoxic effects of Navelbine on tumour derived cells, the most efficient drug or drug combinations were explored using Navelbine+Tamoxifen, Navelbine+Epirubicin and Navelbine+Carboplatin. FM3A cells derived from C3H mouse mammary carcinoma were used in this investigation. Growth rate, mitotic index, labelling index and as being cell kinetics parameters we...

A theoretical study of the kinetic and mechanism of 3-aug-Cope rearrangement in gas phase was performed usingDET methods at B3LYP levels of theory with 6-3114iG(d,p) bass set at 298.I5K. Equilibrium moleculargeometries and harmonic vibrational frequencies of the reactant, transition state Did product were calculated. Then,rate constant and activation thermodynamics parameters were calculated an...
