Extensive studies have been conducted in the past decades to predict the environmental abiotic and biotic redox fate of nitroaromatic and nitramine explosives. However, surprisingly little information is available on one-electron standard reduction potentials (Eo(R-NO2/R-NO2-)). The Eo(R-NO2/R-NO2-) is an essential thermodynamic parameter for predicting the rate and extent of reductive transfor...

Four novel phosphine-substituted ruthenium(ii) polypyridine complexes with nitrogen oxides-trans(P,NO2)-[Ru(trpy)(Pqn)(NO2)]PF6 (trans-NO2), cis(P,NO2)-[Ru(trpy)(Pqn)(NO2)]PF6 (cis-NO2), [Ru(trpy)(dppbz)(NO2)]PF6 (PP-NO2), and cis(P,NO)-[Ru(trpy)(Pqn)(NO)](PF6)3 (cis-NO)-were synthesised (trpy = 2,2':6',2''-terpyridine, Pqn = 8-(diphenylphosphanyl)quinoline, and dppbz = 1,2-bis(diphenylphosphan...

the effects of different concentrations of cdcl2 and alcl3 on nh4+ and no2? oxidation in an aqueous system were investigated. alcl3 had no effect on nh4+ removal and its oxidation to no2?, whereas no2? disappearance was greatly enhanced by alcl3. in contrast, cdcl2 delayed removal of nh4+ and its subsequent oxidation to no2? and also decreased the rate of no2? disappearance. when compared to th...

We conducted a multi-center, 10-year retrospective study of 11 institutions across the USA to identify and describe characteristics, management, outcomes among DRESS patients. There were total 391 pediatric adult inpatients with final diagnosis on discharge. The majority (332/391, 84.9%) had RegiSCAR score qualifying as either possible, probable, or definite DRESS. Only 110/391 (28.1%) would be...

In a prospective study of infants' exposure to nitrogen dioxide (NO2)* and respiratory illness, NO2 concentrations were measured in more than 1,400 homes in Albequerque, NM, From January 1988 through June 1991 (Health Effects Institute Research Report Number 58, Parts I, II and III). This report characterizes the variability in indoor NO2 concentrations across seasons and years, and identifies ...

Background: This study describes and evaluates advanced paramedic practitioner (APP) use of focused cardiac ultrasound (FoCUS) in out-of-hospital arrest (OHCA), relates findings with decisions to terminate resuscitation. The authors report characteristics patients who do/do not undergo a FoCUS examination by APPs, probe positions used whether were associated resuscitation or convey an emergency...

The general principles underlying the acoustic performance of the avian vocal tract are examined both theoretically and experimentally. The formant resonances produced both by the total vocal tract and by the bronchial tubes are evaluated quantitatively, and their dependence upon anatomical parameters is investigated. A simplified cylindrical model for the beak is examined theoretically, and ex...

The simultaneous removal of SO2/NO2 by limestone slurry was studied in a gas-liquid bubbling reactor. Experiments were carried out to find the effect of various operating parameters such as inlet concentration of SO2 and NO2, reaction temperature, O2 content in the flue gas and additive on the SO2 and NO2 removal efficiencies. SO2 removal efficiency decreased with inlet NO2 concentration, react...

Experimental results, such as NO2 hydrolysis and the hypergolicity of hydrazine/nitrogen tetroxide pair, have been interpreted in terms of NO2 dimers. Such interpretations are complicated by the possibility of several forms for the dimer: symmetric N2O4, cis-ONO-NO2, and trans-ONO-NO2. Quantum mechanical (QM) studies of these systems are complicated by the large resonance energy in NO2 which ch...

We compare a full-year (2006) record of surface air NO2 concentrations measured in Israeli cities to coinciding retrievals of tropospheric NO2 columns from satellite sensors (SCIAMACHY aboard ENVISAT and OMI aboard Aura). This provides a large statistical data set for validation of NO2 satellite measurements in urban air, where validation is difficult yet crucial for using these measurements to...
