The influence of low temperature on soybean (Glycine max [L.] Merr. cv. Wells) energy transduction via mitochondrial respiration and dehydrogenases was investigated in this study during imbibition and germination. Mitochondria were isolated from embryonic axes of seeds treated at 10 and 23 C (control) by submergence in H(2)O for 6 hours and maintenance for an additional 42 hours in a moist envi...

in this research the drying of four kinds of vegetables was investigated in a vacuum dryer. the effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °c) was studied. six thin-layer drying models were fitted to drying data and suitable model was selected from them. then effective moisture diffusivity and activation energy of samples were calculated. the diffusio...

Based on measurements of the dynamic viscosity, a strategy is proposed to find an expression that relates the viscosity of an epoxy compound during curing, to the temperature, shear rate, and degree of reaction. It appeared that the dynamic viscosity is a unique function of the effective shear rate (i.e. the product of frequency and strain) over a wide range of frequencies and strains after bei...

The Li⁺ diffusion coefficients in Li⁺-adsorbed graphene systems were determined by combining first-principle calculations based on density functional theory with Kinetic Monte Carlo simulations. The calculated results indicate that the interactions between Li ions have a very important influence on lithium diffusion. Based on energy barriers directly obtained from first-principle calculations f...

Abstract Rendang is a famous traditional food from West Sumatra, Indonesia. Oyster mushroom rendang made oyster mushrooms. Based on its composition, the degradation of fat critical point during storage. Proper packaging can extend shelf life rendang. The purpose this study was to determine that pack in vacuum and no using Accelerated Shelf-Life Testing (ASLT) method according Arrhenius equation...

We have investigated the relationship between function and molecular dynamics of both the lipid and the Ca-ATPase protein in sarcoplasmic reticulum (SR), using temperature as a means of altering both activity and rotational dynamics. Conventional and saturation-transfer electron paramagnetic resonance (EPR) was used to probe rotational motions of spin-labels attached either to fatty acid hydroc...

In order to realize a better description of plastic flow behavior in the warm deformation process GH4149, GH4169 superalloy was compressed by Gleeble-3800 at temperature 700–900 °C and strain rate 0.01–10 s?1. The constitutive model established using artificial neural network (ANN) Arrhenius equation, accuracy compared. results show that average absolute relative error (AARE) ANN is 4.34%. AARE...
