In this study the effects of temperature on anaerobic co-digestion of saw dust with cattle dung is investigated. It also simulates the biogas production from saw dust with cattle dung at various temperatures. Results showed that high temperature could improve the anaerobic digestion and hence increase the biogas production rates. The operating temperatures used in this study were 35°C, 45°C, an...

Introduction: Gluten is a protein found in grains.  Research has shown that the gluten that is in grains of wheat, barley, rye, and oats (to a lesser degree) is toxic to many individuals.  While gluten is essential for the make-up of these 4 grains, our bodies do not need it. Is it healthful?  The protein in today’s wheat is poorly digested and can be harmful.  An estimated 95% of prepared fo...

Monkeys with lesions of perirhinal cortex (PR group) and monkeys with lesions of inferotemporal cortical area TE (TE group) were tested on a modified version of the delayed nonmatching to sample (DNMS) task that included very short delay intervals (0.5 sec) as well as longer delay intervals (1 min and 10 min). Lesions of the perirhinal cortex and lesions of area TE produced different patterns o...

Densities of Aeromonas hydrophila showed distinct thermal optima (25 to 35 degrees C) and thermal maxima (45 degrees C) when measured along thermal gradients created by geothermal and nuclear reactor effluents. Survival of A. hydrophila never exceeded 48 h at temperatures of greater than 45 degrees C. Thermophilic strains could not be isolated at any site.

A simple thin-layer chromatographic system for the separation of the iso,prenologues of vitamin K, is described. This system employs hexadecane-impregnated Kieselguhr thin-layer plates and an acetone-water solvent system. Using ~c-[r-W]naphthol or Z-[l‘X]methyl-x,4-naphthoquinone and DL-[5-3H]mevalonate, the separation of the isoprenologues was confirmed. Each isoprenologue was recovered quanti...
