The stability of 3 transmembrane and 4 transmembrane human vitamin K epoxide reductase models [PDF]
, 2016 3 transmembrane and 4 transmembrane helices models are suggested for the human vitamin K epoxide reductase (VKOR). In this study, we investigate the stability of the human 3 transmembrane/4 transmembrane VKOR models employing a coarse-grained normal mode analysis and molecular dynamics simulation.

Calcium Rubidium Nitrate: Mode-Coupling $β$ Scaling without Factorization [PDF]
Phys. Rev. E 64, 021303 (2001), 2001 The fast dynamics of viscous calcium rubidium nitrate is investigated by depolarized light scattering, neutron scattering and dielectric loss. Fast $\beta$ relaxation evolves as in calcium potassium nitrate. The dynamic susceptibilities can be described by the asymptotic scaling law of mode-coupling theory with a shape parameter $\lambda = 0.79$; the ...

Nitrate Utilization by Nitrate Reductase-deficient Barley Mutants [PDF]
Plant Physiology, 1981 Two nitrate reductase-deficient barley mutants were studied for growth on nitrate and ammonium sources of nitrogen and for resistance to chlorate. Although nitrate reductase-deficient mutants in some species are chlorate-resistant (unable to reduce chlorate to chlorite), the barley mutants used in these studies when grown on nitrate and treated with ...

Non-toxic total nitrogen determination using a low alkaline persulfate digestion
MethodsX, 2020 Measuring total nitrogen, nitrate, and nitrite is critical for compliance with water safety standards. Previous methods for measuring total nitrogen were hazardous, time consuming, and expensive.

Comment on "Atmospheric ionization by high-fluence, hard spectrum solar proton events and their probable appearance in the ice core archive" by A.L. Melott et al [PDF]
, 2016 Melott et al. [2016] suggest that individual solar proton events (SPEs) are detectable as nitrate ion spikes in ice cores. They use the high fluence, high energy (hard spectrum) SPE of 23 February 1956 to calculate an enhancement of HNO3 from the surface to 46 km that is equivalent to a ~120 ng cm-2 nitrate ion spike observed in the GISP2H ice core ...

On the influence of molecular structure on the conductivity of electrolyte solutions - sodium nitrate in water [PDF]
Condens. Matter Phys., 2013, vol. 16, No. 4, 43006:1-12, 2013 Theoretical calculations of the conductivity of sodium nitrate in water are presented and compared with experimental measurements. The method of direct correlation force in the framework of the interionic theory is used for the calculation of transport properties in connection with the associative mean spherical approximation (AMSA).

Sources of reducing equivalents for nitrate reductase in Pisum arvense roots
Acta Societatis Botanicorum Poloniae, 2014 The sources of the nitrate reductase (E.C 1.6.6.1) reducing equivalents were searched for in roots of Pisum arvense by measuring in vivo and in vitro nitrate reductase activity.

Does thiosemicarbazide lead nitrate (TSLN) crystal exist? [PDF]
, 2016 The authors of a recent paper (Optik 125 (2014) 2022-2025) claim to have grown a so called thiosemicarbazide lead nitrate (TSLN) crystal by the slow evaporation method. In this comment we prove that TSLN is actually thiosemicarbazide.

Influence of lead on N03 uptake and reduction in cucumber seedlings
Acta Societatis Botanicorum Poloniae, 2014 The influence of PbCl2 on NO3- uptake and activity level of nitrate (NR) and nitrite MR) reductases in cotyledons and roots of cucumber seedlings was studied.

Plasma-fixated nitrogen as fertilizer for turf grass [PDF]
arXiv, 2021 We investigated the use of plasma-fixated nitrogen, which produces nitrates (NO3-) in water, as a possible nitrogen fertilizer for recreational turf such as ryegrass and bentgrass. Experiments were carried out to study the effects of nitrate concentration on growth, the further effects of adding phosphorous (P) and potassium (K) to the plasma nitrated ...
