1. Whitefish eggs incubated in aerated lake water at controlled tempera tures of 0 degrees , 0.5 degrees , 2 degrees , 4 degrees , 6 degrees , 8 degrees , 10 degrees , and 12 degrees C., failed to hatch at either 0 degrees or 12 degrees C. 0.6 per cent hatched alive at 10 degrees C., 72.67 per cent hatched alive at 0.5 degrees C., and an intermediate proportion hatched at intermediate temperatu...

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...

This study aims to determine the drying rate constant of coconut chips using an oven. Coconut is carried out at temperatures 50 ° C, 60 C and 70 C. Drying has been conducted initial water content 40-50% wb until it reached ± 10% wb. The change moisture was measured every 15 minutes, measurement determined by thermogravimetric method. Newton's model used in determining observation constant. Furt...

Platinum extraction from spent reforming catalysts in iodine solutions under atmospheric pressure at different temperatures, acid concentration, and iodine spices concentration, catalyst particle size, and impeller agitation speed have been studied in our group. In this system, platinum is oxidized from spent catalyst with I3¯ that is formed ...

To estimate the body temperature (BT) of seven dinosaurs Gillooly, Alleen, and Charnov (2006) used an equation that predicts BT from the body mass and maximum growth rate (MGR) with the latter preserved in ontogenetic growth trajectories (BT-equation). The results of these authors evidence inertial homeothermy in Dinosauria and suggest that, due to overheating, the maximum body size in Dinosaur...

The physical aging of amorphous polymers induces changes in material properties, which are challenging to detect situ industrial settings. Here, we present a nondestructive nonlinear ultrasonic evaluation technique that enables localized measurements the combined effects temperature and time polymers, without needing remove materials. proposed is demonstrated using commercial grade poly(vinyl c...

Abstract During processing and bubble growth processes, the melt viscosity changes with temperature, pressure, blowing agent concentration. Therefore, measurement prediction methods for characterization in terms of dependency are needed. This study demonstrates applicability in-line measurements during foam injection molding process a model superposition prediction. In present study, polystyren...

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...
