Submitted: Jul 19, 2013; Accepted: Sep 3, 2013; Published: Sep 11, 2013 Abstract: The study of isotopic ratios of oxygen and carbon has gained importance to determine the origin of ore bearing fluids, carbon origin and also to determine the formation temperature of non-sulfide lead and zinc minerals. In order to determine the origin of fluids and carbon existing in zinc carbonate minerals in Ch...

W ith nearly two-thirds of the population afflicted, the Nuu-chah-nulth Indians of Vancouver Island in British Columbia have one of the highest rates of arthritis in the world. Often passed down family lines, the genetics of arthritis in this unique population was studied extensively during the 1980s by Richard Ward, now head of the Institute of Biological Anthropology at the University of Oxfo...

Iodoglucoazomycin (I-GAZ; N-(2-iodo-3-(6-O-glucosyl)propyl)-2-nitroimidazole), a non-glycosidic nitroimidazole-6-O-glucose adduct, was synthesized, radioiodinated, and evaluated as a substrate of glucose transporter 1 (GLUT1) for radiotheranostic (therapy+diagnostic) management of hypoxic tumors. Nucleophilic iodination of the nosylate synthon of I-GAZ followed by deprotection afforded I-GAZ in...

An experiment was conducted to find out variation in isolated Rhizoctonia solani based on radial mycelial growth and sclerotial production. Five isolates of Rhizoctonia solani representing five clusters group were selected and were grown at different levels of temperature and pH on potato dextrose agar (PDA). It was observed that optimum temperature and pH for growth and scierotial production v...

Detection of mineralized zones based on ores and gangues is important for mine planning and excavation operation. The major goal of this research work was to determine the zones based on ores and gangues by a combination of fractal and factor analysis in the Chah Gaz iron ore (Central Iran). The Concentration-Volume (C-V) fractal method was carried out for Fe, P and S, which indicated that the ...

We introduce an approach to revealing the likelihood of different population histories that utilizes an explicit model of sequence evolution for the DNA segment under study. Based on a phylogenetic tree reconstruction method we show that a Tamura-Nei model with heterogeneous mutation rates is a fair description of the evolutionary process of the hypervariable region I of the mitochondrial DNA f...

gaz is one of the traditional food products. ingredient of gaz has certain differences compared with other sweets & snacks, which in the preparation of them no oils, starch and flour is used. adverse color, taste and odor in gaz may has been created by oxidation in nuts at store condition. on the other hand, gaz becomes dry in inappropriate packaging at areas with low humidity and becomes soft ...
