Calculation of excess quantities of ethylene glycol + water binary fluid systems at seven absolute temperatures (293.15 to 353.15) K from experimentally determined values of density and shear viscosity were presented in previous work. The examination of related functions beside the quality of correlation from several equations on these experimental values has also been reported. Considering...

We derive a dynamic field theory for a kinetically constrained model, based on the Fredrickson-Andersen model, which we expect to describe the properties of an Arrhenius (strong) supercooled liquid at the coarse-grained level. We study this field theory using the renormalization group. For mesoscopic length and time scales, and for space dimension d>/=2 , the behavior of the model is governed b...

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...

A soluble delipidized (Na + K)-stimulated ATPase was obtained from rabbit kidney outer medulla by the use of sodium deoxycholate. The activity of this enzyme was stimulated ZO-fold to an activity of 100 to 120 pmoles of Pi per mg of protein per hour by either phosphatidylserine or phosphatidylglycerol. The effect of the fluidity of the hydrocarbon region of the phospholipid bilayers on this re-...

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...
