In the title hydrated mol-ecular salt, C(7)H(7)N(2) (+)·C(2)HO(4) (-)·0.5H(2)O, contains a 3-cyano-anilinium cation, a hydrogen oxalate anion and half a water mol-ecule in an asymmetric unit. The dihedral angle between the CO(2)(H) and CO(2) planes of the hydrogen oxalate ion is 7.96 (1)°. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a layer lying paralle...

Very-high-resolution (VHR) optical imaging satellites can offer precise, accurate, and direct measurements of snow-covered areas (SCA) with sub-meter to meter-scale resolution in regions complex land cover terrain. We explore the potential Maxar WorldView-2 WorldView-3 in-track stereo images (WV) for snow mapping at two sites Western U.S. different regimes, topographies, vegetation, underlying ...

statement of the problem subgingival irrigation with an antimicrobial agent after scaling and root planing (srp) is assumed to be able to kill the bacteria left behind after mechanical debridement. 3% h2o2 is used in the treatment of periodontal disease and it has been shown effective in killing anaerobic pathogens. purpose the aim of this study was to evaluate the clinical effects of subgingiv...

One of the varieties of pores, often found in natural or artificial building materials, are the so-called blind pores of dead-end or saccate type. Three-dimensional model of such kind of pore has been developed in this work. This model has been used for simulation of water vapor interaction with individual pore by molecular dynamics in combination with the diffusion equation method. Special inv...

Salicylhydroxamic acid inhibited the luminol-dependent chemiluminescence of human neutrophils stimulated by phorbol 12-myristate 13-acetate or the chemotactic peptide N-formylmethionyl-leucyl-phenylalanine (fMet-Leu-Phe). This compound had no inhibitory effect on the kinetics of O2.- generation or O2 uptake during the respiratory burst, but inhibited both the peroxidative activity of purified m...

Melissa officinalis L. is a medicinal plant with a large variety of pharmacological effects and traditional applications. This study aimed to evaluate the protective and antioxidant activities of the extract of M. officinalis aerial parts on human umbilical vein endothelial cells (HUVECs) under oxidative stress induced by H2O2. Cells were incubated with H2O2 (0.5 mM, 2 h) after pretreatment wit...

background: poly chlorinated biphenyls (pcbs) are a class of chlorinated organic chemicals that do not easily degrade in the environment. this study was conducted to determine the effect of microwave rays, hydrogen peroxide, dioxide titanium and ethanol solvent on the degradation of pcbs. methods: a 900w domestic mw oven with a fixed frequency of 2450 mhz was used to provide mw irradiation. ray...

The aim of this article is to discuss some of the notions and applications of random walks on finite graphs, especially as they apply to random graphs. In this section we give some basic definitions, in Section 2 we review applications of random walks in computer science, and in Section 3 we focus on walks in random graphs. Given a graphG = (V,E), let dG(v) denote the degree of vertex v for all...

Abastract This study aimed to evaluate the transenamel and transdentinal penetration of hydrogen peroxide (H202) applied to bovine teeth pigmented with black tea at different intensities. The following groups were formed DW: immersion in distilled water; BT100: immersion in an infusion of 1.6 g of black tea per 100 mL distilled water; BT10: immersion in an infusion of 1.6 g black tea per 10 mL ...
