Metal oxide nanomaterials are important and excellent materials, because of its special properties like chemical stability, high photo catalytic activity, high electric permittivity, non-toxic nature. So it is used in various applications like optical, electrical, electronic, antiseptic, antibacterial, environmental, semi conductors and catalytic devices. Present work focused on to synthesis of...

This study compares the chemical composition of rainwater samples collected at two sampling sites, the first situated in the Rijeka city centre and the second in a suburban site 120 m above the sea level. The rainwater samples were analysed for precipitation weighted average concentrations of hydrogen, sulphate, nitrate, chloride, ammonium, sodium, potassium, calcium, and magnesium. The results...

This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...

The sites of lead phosphate precipitation in mouse bladder smooth muscle incubated with adenosine triphosphate and lead nitrate were studied by electron microscopy. The media constituents and incubating conditions were independently varied so that we could determine optimal conditions for histochemical demonstration of ATPase activity in agranular endoplasmic reticulum. Specimens of glutaraldeh...

Although there has been significant interest in the develop ment of environmentally friendly pyrotechnics, the develop ment of cost effective barium free green light emitting pyro technic formulations has remained elusive. Many barium compounds are human health hazards, and recent work by Steinhauser has shown that barium ores as raw materials may contain radioactive radium. Recent papers by Kl...

The Nar two-component regulatory system, consisting of the dual sensor-transmitters NarX and NarQ and the dual response regulators NarL and NarP, controls the expression of various anaerobic respiratory pathway genes and fermentation pathway genes. Although both NarX and NarQ are known to detect the two environmental signals nitrate and nitrite, little is known regarding the sensitivity and sel...

Abstract A simultaneous DSC–thermomicroscopy system (DSC450 Linkam Scientific) was applied to the study of phase transitions in rubidium nitrate and silver iodide, oxidation polyethylene, thermal degradation polylactic acid magnesium hexahydrate, reversible thermochromic inks. The results demonstrated benefits obtaining optical data, both images light intensity measurements, with DSC, particula...

The effect of Mo on nitrate reductase and nitrogenase activities as well as the growth and mineral nutrition of wheat inoculated with Azospirillum brasilense in greenhouse pot experiments under drought stress conditions was evaluated. Plant dry weight and total N-yield appeared to be drastically affected by the severe drought stress. This inhibition was associated with a decline in nitrate redu...

different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by aspergillus oryzae in submerged fermentation. enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. results ...
