The temperature characteristics (micro) for two activities (heart beat and respiratory movements) studied simultaneously in the same individual organism (Daphnia magna) were always found to differ in magnitude. The type of graph obtained when the frequency of these movements was plotted according to the Arrhenius equation was also distinctly different for each activity. The organism therefore d...

In the present work, the effective moisture diffusivity and activation energy were calculated using an infinite series solution of Fick’s diffusion equation. The results showed that increasing drying temperature accelerated the drying process. All drying experiments had only falling rate period. The average effective moisture diffusivity values varied from 2.807x10 to 6.977x10m s over the tempe...

This paper presents a model-based cell-health-conscious thermal energy management method. An Arrhenius equation-based mathematical model is firstly identified to quantify the effect of temperature on the cell lifetime of a Nickel Metal Hydride (NiMH) battery pack. The cell aging datasets collected under multiple ambient temperatures are applied to extract the Arrhenius equation parameters. The ...

1. The effect of temperature on the reaction time of Mya to light is mainly confined to the latent period. The sensitization period, representing a photochemical process, is changed comparatively little. 2. The relation between the latent period and the temperature is adequately expressed by the Arrhenius equation, for temperatures below 21 degrees C. Above this temperature, the latent period b...

We determine both barrier heights and prefactors for protein folding by applying constraints determined from experimental rate measurements to a Kramers theory for folding rate. The theoretical values are required to match the experimental values at two conditions of temperature and denaturant that induce the same stability. Several expressions for the prefactor in the Kramers rate equation are...

The rate of hydrolysis of trans -[Cr(NH ) F ] was obtained as a function of acid concentsation in perchloric, sulfuric and nitric acid at 3Q°C. The results have been analyzed by the treatment of Bunnett and Olsen. Values of the parameter ?in Olsen equation are consistent with the participation of water as a proton-wansfer agent in the rate-determining step. The Arrhenius plot for perchlori...

The gliding movements of certain Cyanophyceae, Thiobacteriales, and gregarines provide relatively uncomplicated types of comparable activities suitable for quantitative observation. In spite of much discussion, little is known as to the mechanism of this sort of progression. Interpretations have been advanced by a number of writers, t but data required for formulation of a theory of this sort o...

In this work, C2-Methylated [C3DMIM+][I?] versus C2-Protonated [C3MIM+][I?] Imidazolium-Based Ionic Liquids containing iodide anion, have been synthesized and characterized using 1H 13C NMR spectroscopy methods. order to investigate the methylation effect on thermal properties, we rely three additional analysis techniques. The behavior confirmed that methylated IL is more stable than protonated...
