Serratia marcescens has been studied to show a higher degradation potential for organo-phosphorus pesticides. This property made it useful as bioremediation agent. The bacterial cell was bio-stimulated in luria beterni broth at selected experimental temperature ranging from 25 ºC – 40 ºC. highest biomass recorded 35 range 7.56 -8.10mg/ml single strength and double yeast extract beterni, respect...

in order to determine the copper status and correlation between the ceruloplasmin and copper of serum and among the copper of serum, liver and kidney of slaughtered goats in shahrekord, blood, liver and kidney samples (10 gr) from 100 goats were gathered. the amounts of ceruloplasmin and copper of serum, liver and kidney were measured by sunderman - nomoto and shimadzu atomic absorption method,...

background: this study aims to investigate the patterns of bioaccumulation and depuration of copper in the selected kidney and liver of capoeta fusca. methods: the fish were collected between september and november 2010 from a qanat in birjand. they were exposed to two types treatments with copper (0.25 and 0.75 mg/l) for a period of 41 days. the fish under study were exposed to the above-menti...

The main aim of this research is to determine optimal leaching conditions; Eh, pH and complexing agent concentrations, for recovery of Copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. This has been preceded by a theoretical approach and numerical and computer calculation. Pot...

Tepe Sagzabad, a site situated on the Qazvin Plain of north-central Iran, was excavated from 1970 to 1998 by the Institute ofArchaeology of Tehran University. Recent excavations by H. Tala’i (1997-1999) yielded some metal artifacts dating to theEarly Iron Age. Ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (ICP-OES), scanning el...

introduction: among soil species earthworms are ubiquitous, abundant and important for soil processes, constituting the largest terrestrial faunal biomass and are also impacted by soil pollutants. the primary purpose of this study was to determine whether changes in earthworm biomass and behavior could serve as a good indicator for copper toxicity in soil systems. another aim of the study was t...

this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

A field experiment was conducted in the years 2008– 2010 at the Research Station of the Faculty of Agricultural Sciences, University of Life Sciences in Lublin, on brown soil with slightly acidic pH and average abundance of copper, zinc, manganese, and iron. The experiment was set up in a randomized split-plot design with four replications, with two methods for controlling weed infestation: I. ...

in this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. the copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. reaction temperature and concentration ratio of the reducing agent to the precursor (r/p) as two main conditions i...

background: it is well established that oxidative modification of low density lipoprotein (ldl) plays a causal role in human atherogenesis and the risk of atherosclerosis is increased in patients with diabetes mellitus. we examined the in vitro effect of glucose on native and glycated ldl oxidation using copper ion dependent oxidation system. methods: in this study, ldl was isolated from plasma...
