The Sungun copper deposit is located in about 40km north west of Ahar city in the east Azarbaigan province of Iran. The total geological ore deposit is estimated to be 740 million tons. In this study using all information from exploration and geotechnical studies of the area, final pit limits of Sungun copper deposit is designed by the 2-D Lerchs & Grossmann Algorithm. By this method, from 740 ...

There is increasing recognition that inflammatory liver disease in dogs is associated with abnormal hepatic copper (Cu) concentrations. Abnormal hepatic Cu accumulation results as either a primary metabolic defect in Cu metabolism unique to some breeds or as a secondary event associated with chronic hepatic cholestasis resulting in a decrease in biliary excretion of hepatic Cu. Abnormal hepatic...

incorporation of copper species into silica matrix was performed by the sol-gel method. copper ions and copper particles were doped using two different copper sources; cu(no3)2.3h2o and copper particles chemically synthesized.the particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. on the other han...

This study was carried out to synthesize 1D inorganic nanostructure using an electrochemical method without any template and additives. Copper foils were anodized in a KOH bath and were tested for their antibacterial performance. After anodizing, the obtained samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the corresponding morphology an...

AIM To assess plasma zinc and copper concentration in individuals with autism and correlate these levels with symptom severity. SUBJECTS AND METHODS Plasma from 102 autistic individuals, and 18 neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Copper and zinc levels and Cu/Zn were analyzed for possible correlation with severity o...

We have previously shown that chelated copper stimulates the release of luteinizing hormone-releasing hormone (LHRH) from isolated hypothalamic granules. In this study, we wished to ascertain if chelated copper acts on hypothalamic neurons to stimulate LHRH release and, if so, what is the ligand specificity of this interaction. An in vitro system of explants of the median eminence area (MEA) wa...

Abstract Background: Despite the high prevalence and recurrence of bladder cancer, researches about the role of trace elements such as iron, copper and zinc in bladder cancer are limited in number. In the present study the concentration of Iron, Copper and Zinc, (Fe, Cu and Zn) were determined in the serum of patients with bladder cancer and compared with the level of these trace elements ...

The distribution, enrichment, accumulation, and potential ecological risk of copper (Cu) in the surface sediments of northern Kaohsiung Harbor, Taiwan were investigated. Sediment samples from 12 locations of northern Kaohsiung Harbor were collected and characterized for Cu, aluminum, water content, organic matter, total nitrogen, total phosphorous, total grease and grain size. Results showed th...
