Nitrate Reductase Activity, Nitrate Uptake and Iodine Speciation in the Marine Environment
… uptake by measuring the activity of nitrate reductase (NRA). In addition, because it has long been suspected that the biological reduction of IO<sub>3</sub><sup>–</sup> to I<sup>–</sup> may be mediated by nitrate reductase (NR), this research investigated the ability of NR to catalyze …

Nitrate: metabolism and development
… aim of this thesis was to study the effect of nitrate on primary metabolism and in development of the model plant Arabidopsis thaliana. The present work has two separate topics. First, to investigate the GDH family, a small gene family at the interface between nitrogen and carbon metabolisms. …

Kinetics reactions of Ammonium Nitrate-Sodium Nitrite Reaction and Ammonium Nitrate Emulsion Explosives
… and control the gasification rates in ammonium nitrate emulsion explosive using ammonium nitrate-sodium nitrite reaction. This reaction produces N2 gas which is the sensitizer in emulsion explosives. The NH4NO3-NaNO2 gassing reaction produces N2 gas and so the reaction could be followed by the …

Salivary Reduction of Dietary Nitrate
… known mostly for its vasodilatative effects. Nitrate (NO3-) acts as an important NO source through reductive physiological pathways. Basal plasma NO3- levels are a sum of the oxidation of endogenous NO and ingested dietary NO3-. Approximately 25% of dietary NO3- is recovered by the salivary …

Nitrate reductase in apple trees
Factors affecting the in vivo nitrate reductase assay were investigated in order to optimize the assay conditions for various tissues of MM 106 apple trees. Optimum concentrations of nitrate and phosphate for in vivo nitrate reductase activities ranged from 50 to 100 mM and were tissue-specific. …

Hot spots in ammonium nitrate
Ammonium nitrate (AN) is commonly used as an explosive and as a fertilizer. In both roles it is provided as prills or pellets, approximately spherical and a few millimetres in diameter. The microstructures of several commercially-available AN compositions were investigated using environmental …

The solvation of cellulose nitrate
… changes in solvation of a sample of cellulose nitrate in an acetone-water solvent-non solvent system as the composition of the liquid phase is varied over a range from solvent rich to solvent poor.

Nitrate and ammonium interactions in maize.
… by a plant for its growth and development. Nitrate (NO₃⁻) and ammonium (NH₄⁺) are the predominant forms of N available to plants in agricultural soils. Plants have the ability to absorb both these forms efficiently from the soil solutions. With soil solution concentrations of NH₄⁺ being much …

Computational dissection of nitrate transport mechanism
… per unit of added nitrogen. For plants, nitrate is one of the two major nitrogen sources, which is taken up from the soil through nitrate transporters. Despite recent breakthroughs in structural biology, our knowledge of the molecular nature and regulation of nitrate transporters is far …

Risk assessment formulation for nitrate leaching
… Probability distributions of yearly-maximum nitrate concentrations were developed for each application rate at each site using the simulated nitrate concentrations. The probability of failure (exceeding 10 mg/L NO₃-N) for each application rate was determined from its corresponding …

A selective fractionation of cellulose nitrate
… Polymer from 5 different samples of cellulose nitrate, covering a D.S. Range of 10.97-13.35%-N, has been accomplished.

Biochemical Characterizations of a Soybean (Glycine Max (L.) Merr. ) Nitrate Reductase Mutant and Crude and Purified Nitrate Reductases
… Merr. cv. Williams leaves contain three forms of nitrate reductase (NR), two functional in the absence of NO(,3)('-) in the growth medium (constitutive forms; c(,1)NR, c(,2)NR) and the third active after induction by NO(,3)('-) (inducible form; iNR). Experiments were conducted to determine the …
