Abstract The influence of cobalt, copper, iron(III), manganese and zinc nitrate salts on phase transitions thermal stability ammonium (AN) has been studied discussed. Differential analysis/differential scanning calorimetry coupled with thermogravimetry mass spectrometry were used to evaluate the analyzed systems. Each salt was appropriately mixed create samples AN:salt ratios 4:1, 9:1 49:1. It ...

LTHOUGH the bone marrow usually appears to be normal or even hyperplastic in cases of anemia associated with infection,’ the anemia is refractory to therapy, being relieved only when the underlying infection is successfully eradicated. The anemia is accompanied by a profound metabolic disturbance as indicated by the finding of hypoferremia, hypercupremia, and elevated erythrocyte protoporphyrin...

Abstract : Helminthosporium tetramera was a pathogen of Saccharum Officinarum, isolated from diseased leaves Nashik district and used for the present study. Pathogen grown on Czapek-Dox liquid medium substituting or adding different carbon, nitrogen to study biomass production. The growth as dry mycelial observed 8th day incubation period. A grate extent variation nitrogen. Among carbon source,...

CHEMICAL investigations have shown that alkaline phosphatase is present in the retina (De Conciliis, 1934; Reis, 1951). In these investigations the whole retina was homogenized and the enzyme estimated in extract. Obviously the estimations of enzyme activity by such a necessarily gross method give no idea of the exact distribution of the enzyme in this, functionally, so finely differentiated ti...

The synthesis of bulk pure Co3O4 catalysts by different routes has been examined in order to obtain highly active for lean methane combustion. Thus, eight methodologies, which were selected based on their relatively low complexity and easiness scale-up, evaluated. investigated procedures direct calcination two cobalt precursors (cobalt nitrate hydroxycarbonate), basic grinding route, precipitat...

Assessments of groundwater pollution parameters were carried out in samples collected from selected shallow hand-dug wells across Ilora township. The analysed nitrate, trace elements including, iron, cobalt, chromium, manganese, zinc, arsenic, cadmium and lead, bacteria count water; using spectrophotometric method, HM Metalyser 5000 multiple tube techniques respectively. pH the was between 6.4 ...

The equilibrium lies well over on the side of free phosphate. Studies of the histochemical localization of alkaline phosphatase were made by Robison (1923), who showed that if a section of bone is incubated in a solution containing a phosphoric acid ester and calcium, the phosphate which is split off from the ester by phosphatase is precipitated as calcium phosphate in the vicinity of the enzym...

A set of multicomponent perovskite oxide nanoparticles based on La1-xSrxCo1-yFeyO3-δ(LSCF) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (LT-SOFC) as cathode materials.  The precursor materials used in this synthesis were lanthanum nitrate hexahydrate [La(NO3)<su...
