Photolysis of ferric ions in the presence of sulfate or chloride ions: implications for the photo-Fenton process
(ROYAL SOC CHEMISTRY, 2009)
The photo-Fenton process (Fe(2+)/Fe(3+), H(2)O(2), UV light) is one of the most efficient and advanced oxidation processes for the mineralization of the organic pollutants of industrial effluents and wastewater. The overall ...
The isotropic nuclear magnetic shielding constants of acetone in supercritical water: A sequential Monte Carlo/quantum mechanics study including solute polarization
(AMER INST PHYSICS, 2008)
The nuclear isotropic shielding constants sigma((17)O) and sigma((13)C) of the carbonyl bond of acetone in water at supercritical (P=340.2 atm and T=673 K) and normal water conditions have been studied theoretically using ...
Diffusion anomaly and dynamic transitions in the Bell-Lavis water model
(AMER INST PHYSICS, 2010)
In this paper we investigate the dynamic properties of the minimal Bell-Lavis (BL) water model and their relation to the thermodynamic anomalies. The BL model is defined on a triangular lattice in which water molecules are ...
THE SPECTRAL EVOLUTION AND EJECTA OF RECURRENT NOVA U Sco IN THE 2010 OUTBURST
(IOP PUBLISHING LTD, 2010)
Synoptic spectroscopic observations of the U Sco 2010 outburst from maximum light to quiescence as well as a contemporaneous X-ray observation are presented and analyzed. The X-ray spectrum 52 days after outburst indicates ...
Effect of chemical treatment on the mechanical properties, water vapour permeability and sorption isotherms of gelatin-based films
(JOHN WILEY & SONS LTD, 2008)
Proteins contain hydrophilic groups, which can bind to water molecules through hydrogen bridges, resulting in water vapour adsorption. An increase in the degree of cross-linking can be a method to improve the cohesiveness ...
Conservative approach for a clinical resolution of enamel white spot lesions
(QUINTESSENCE PUBLISHING CO INC, 2011)
Enamel white spot lesions in anterior teeth that compromise esthetics are common. Microabrasion is indicated, since it affects enamel superficially. An acid-abrasive slurry with 37% phosphoric acid with pumice was used on ...
CztR, a LysR-Type Transcriptional Regulator Involved in Zinc Homeostasis and Oxidative Stress Defense in Caulobacter crescentus
(AMER SOC MICROBIOLOGY, 2010)
Caulobacter crescentus is a free-living alphaproteobacterium that has 11 predicted LysR-type transcriptional regulators (LTTRs). Previously, a C. crescentus mutant strain with a mini-Tn5lacZ transposon inserted into a gene ...
Constraining the orbital orientation of eta Carinae from H Paschen lines
(WILEY-BLACKWELL, 2009)
During the past decade, several observational and theoretical works have provided evidence of the binary nature of eta Carinae. Nevertheless, there is still no direct determination of the orbital parameters, and the different ...
Ohr (Organic Hydroperoxide Resistance Protein) Possesses a Previously Undescribed Activity, Lipoyl-dependent Peroxidase
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2010)
The Ohr (organic hydroperoxide resistance) family of 15-kDa Cys-based, thiol-dependent peroxidases is central to the bacterial response to stress induced by organic hydroperoxides but not by hydrogen peroxide. Ohr has a ...
Modulation of rat neutrophil function in vitro by cis- and trans-MUFA
(CAMBRIDGE UNIV PRESS, 2009)
In the present study, the effects of trans-MUFA, elaidic acid (EA; 18 : 1-9t) and vaccenic acid (VA; 18 : 1-11t) on rat neutrophil functions were compared with those of cis-monounsaturated oleic acid (OA) (18 : 1-9c) and ...
