Objective: Potato is the fourth important food crop after wheat, rice and maize. Shrinkage  of  food  materials  has  a negative  consequence  on  the  quality  of  the dehydrated product. The main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. Methods: In this work, the effect of the infrared radiation...

in this research, chitosan was used for the removal of cr (vi) ions from aqueous solution. the effect of parameters like solution ph, initial cr (vi) concentration, agitation time, amount of adsorbent and agitation speed on the adsorption process was studied. the experimental equilibrium data were analyzed by using various models such as langmuir and freundlich. freundlich isotherm model fitted...

An improved version of a recently developed stochastic cluster dynamics (SCD) method [Marian, J. and Bulatov, V. V., J. Nucl. Mater. 415 (2014) 84-95] is introduced as an alternative to rate theory (RT) methods for solving coupled ordinary differential equation (ODE) systems for irradiation damage simulations. SCD circumvents by design the curse of dimensionality of the variable space that rend...

In this research work, activated carbon prepared locally from Thespesia Populnea bark(TPC) was examined for the removal of cobalt (II) from aqueous solution. The main parameters, like effect of adsorbent dosage, Co (II) concentrations, effect of contact time and effect of pH was studied in batch experiments. The experimental results were analyzed by using Langmuir, Freundlich, adsorption isothe...

Hydrogen atom transfer reactions between the substrate and coenzyme are key mechanistic features of all adenosylcobalamin-dependent enzymes. For one of these enzymes, glutamate mutase, we have investigated whether hydrogen tunneling makes a significant contribution to the mechanism by examining the temperature dependence of the deuterium kinetic isotope effect associated with the transfer of a ...

in the present work, a titanium-based ziegler-natta catalyst was employed to synthesize ultra molecular weight polyethylene in a slurry medium. the effect of different parameters such as ethylene pressure, temperature, catalyst composition, and hydrogen pressure was studied. as the results indicate, increasing either [al]/[ti] ratio or temperature causes polymerization rate to go through a maxi...

Let M be a triangulated, orientable 2-manifold of genus g without boundary, and let h be a height function over M that is linear within each triangle. We present a kinetic data structure (KDS) for maintaining the Reeb graph R of h as the heights of M’s vertices vary continuously with time. Assuming the heights of two vertices of M become equal only O(1) times, the KDS processes O((κ + g)n polyl...
