The present study has investigated the synthesis of copper nanoparticles via copper dismutation reaction in an aqueous solution and ambient conditions. Copper (II) chloride hydrate ( ), sodium oleate (SO), sodium chloride (NaCl) and ethylene diamine (EN) have been used as copper (I, II) ions source, surfactant, chloride ions supplier and ligand, respectively. Also, an amount of hydrochloric aci...

The most common types of blood protozoa in chickens are from the phylum Apicomplexa, including Plasmodium, Leucocytozoon and Haemoproteus. Blood protozoan diseases can cause decreased egg production, stunting death poultry farms. This study aims to identify calculate prevalence infection casted off laying sold at Wonokromo Market, Surabaya City. One hundred samples were taken by purposive sampl...

functionalization of multiwalled carbon nanotubes (mwcnts) with nh2 groups under a one pot reaction is studied. during the first step of the reaction, cl and chcl2 groups were attached to the surfaces of mwcnts through an electrophilic addition reaction. in the second step of process, cl atoms were replaced with nh2 and amino groups (ethylene diamine and butyl amine) under a nucleophilic substi...

the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

Thermophilic Bacillus sp. GUS1, isolated from  a soil  sample obtained from citrus garden, produced at least three proteases as detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and zymogram analysis. The enzymes were stable in the alkaline pH range (8.0-12.0), with the optimum temperature and pH range of the proteases being 70ºC and 6.0-12.0, respectively. All th...

A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...

Background: Milk fever in cattle, sheep and goats occurs  around the time of parturition and is caused by hypocalcemia. OBJECTIVES: The aim of this study was to investigate the physiological effects of experimental hypocalcemia on electrocardiography, hematology and serum biochemical changes in Markhoz goat breed. METHODS: Ethylene diamine tetra- acetate solution 4.6% was intravenously infused ...
