Ethanol is commonly used as a solvent in extracting glucomannan from Porang. However, the extraction process often leaves ethanol. The remaining ethanol can be re-distilled to save use of it. re-distillation with input volumes 50L and 100L variations heating temperatures 80°C, 85°C, 90°C. This study aimed analyze effect volume temperature on output determine constant change using kinetics Arrhe...

It is difficult to investigate folding kinetics by conventional atomistic simulations of proteins. The replica exchange molecular dynamics (REMD) simulation technique enhances conformational sampling at the expenses of reduced kinetic information, which in REMD is directly available only for very short time scales. Here, we propose a procedure for obtaining kinetic data from REMD by making use ...

THIS paper is primarily concerned with an attempt to evaluate the temperature coefficients for the velocity of haemolysis in two simple haemolytic systems, the lysin being saponin in the first and sodium taurocholate in the second. There is nothing in the literature to suggest that the problem is one of any complexity, for Arrhenius (1915) and his collaborators, by whom most of the existing inv...

Intense but short electrical fields can increase the permeability of the cell membrane in a process referred to as electroporation. Reversible electroporation has become an important tool in biotechnology and medicine. The various applications of reversible electroporation require cells to survive the procedure, and therefore the occurrence of irreversible electroporation (IRE), following which...

Abstract Hastelloy C276 is widely used in the new generation of nuclear power plants, and hot deformation optimum way to form part. In this investigation, constitutive modeling alloy are researched, processing maps drawn. The results show that strain rate temperature have remarkable impacts on behaviors alloy. yield behavior flow stress predicted based Arrhenius equation, correlation coefficien...

The purpose of the study was to investigate microwave selective heating phenomena and their impact on heterogeneous chemical reactions. We also present a tool which will help microwave chemists to answer to such questions as "My reaction yields 90% after 7 days at reflux; is it possible to obtain the same yield after a few minutes under microwaves?" and to have an approximation of their reactio...

The compressibility and heat of reaction influence on the scalar mixing in decaying isotropic turbulence and homogeneous shear flow are examined via data generated by direct numerical simulations (DNS). The reaction is modeled as one-step, exothermic, irreversible and Arrhenius type. For the shear flow simulations, the scalar dissipation rate, as well as the time scale ratio of mechanical to sc...
