the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

the reaction of ch3o2 radicals with acetaldehyde on the solid surface of nh4no3 has been studied in a flow capillary reactor at low pressure and room temperature. the experiments were performed using epr spectrometer combined with the kinetic method of radicals freezing. peroxy radicals revealed an oscillation complex behavior during the process regarding to the phenomenon of radicals multiplic...

El uso eficiente del nitrógeno es una técnica utilizada para mejorar los rendimientos sin el aporte excesivo de fertilizantes nitrogenados, mismo modo, nanofertilizantes alternativa solucionar problemas nutricionales con mayor eficiencia y precisión, ambos propósito incrementar productividad cultivos. Por lo que objetivo presente estudio fue evaluar la aplicación foliar nanofertilizante molibde...

A new type of cell for countercurrent electromigration of molten nitrates is proposed, in which molten NH4NO3 is employed just above its melting point in a large cathode compartment. This cell can be used effectively without trouble of corrosion for the purpose of (1) enrichment of 6Li, (2) enrichment of heavier isotopes such as 7Li, and (3) measurements of relative internal mobility difference...

A novel mathematical model has been developed to aid the formulation of emulsion explosives. This mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a MS Excel program. The effects of the different content of NH4NO3, NaNO3, H2O, and span-80 and composite fuel oil...

In the present work, hybrid polymer electrolyte based on carboxymethyl cellulose-polyvinyl alcohol-ammonium nitrate-ethylene carbonate (CMC–PVA–NH4NO3–C3H4O3) become promising materials that has demonstrated outstanding physical properties as an electrolytes system in solar cell. frame of cell progress, electrical conductivity and optical bandgap are equally explored. The characterization is ca...

The mechanisms involved in regulating high-affinity ammonium (NH4+) uptake and the expression of the AtAMT1 gene encoding a putative high-affinity NH4+ transporter were investigated in the roots of Arabidopsis thaliana. Under conditions of steady-state nitrogen (N) supply, transcript levels of the AtAMT1 gene and Vmax values for high-affinity 13NH4+ influx were inversely correlated with levels ...

In vitro experiment was performed by taking petrol pump soils and diesel in flasks with the micronutrients and macronutrients supplements. Cemented bioreactors having sterilized soil and diesel was used for in vivo analysis of diesel hydrocarbon degradation. There were two sets of experiments, first having three bioreactors (1) inoculated by KI. pneumoniae subsp. aerogenes with soil and diesel;...

The effect of different nitrogen sources – KNO3, NH4NO3 and NH4Cl – on glutamine synthetase and glutamate synthase activities of radish cotyledons (Raphanus sativus L.) in the presence or absence of light was investigated. The plants were treated with different phytohormones viz. Kinetin (KN), gibberellic acid (GA) and abscisic acid (ABA). In dark ammonia supplementation was effective in promot...
