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...

The use of accelerated temperature stability studies using the Arrhenius relationship is routine for estimating the stability of a drug at room temperature. Therefore, the acceleration method is used to determine the expiration date of dexamethasone aqueous formulation manufactured in Iran. A high-performance liquid chromatography (HPLC) method utilizing ultraviolet (UV) detection for dexa...

We report results from the molecular dynamics simulations of a binary colloidal mixture subjected to an external potential barrier along one spatial directions at low volume fraction, {\phi} = 0.2. The variations in asymmetry do not change smaller particles, showing Arrhenius diffusion. However, larger particles shows crossover sub-Arrhenius super-Arrhenius diffusion with temperatures and fract...

BACKGROUND Different mechanistic models have been used in the literature to describe the enzymatic hydrolysis of pretreated biomass. Although these different models have been applied to different substrates, most of these mechanistic models fit into two- and three-parameter mechanistic models. The purpose of this study is to compare the models and determine the activation energy and the enthalp...

Typically, in accelerated life testing analysis, only probability distributions possessing shape parameters are used to fit the experimental data, and many with no have been excluded, including fundamental ones like normal distribution, even when they good fitters data. This work shows that coefficient of variation is a replacement for parameter allows using this context. The focuses on Arrheni...

Abstract In this research article, we examined the Darcy-Forchheimer 3D in bioconvection Casson nanofluid flow light of a whirling disk with Arrhenius Activation Energy and thermal Radiation. The governing equations are converted to similarity solved afterward by utilizing Homotopy Analysis Method on behalf several controlling parameters. findings from study show, that radial velocity tangentia...

This paper draws attention to selected experiments on enzyme-catalyzed reactions that show convex Arrhenius plots, which are very rare, and points out that Tolman's interpretation of the activation energy places a fundamental model-independent constraint on any detailed explanation of these reactions. The analysis presented here shows that in such systems, the rate coefficient as a function of ...
