Abstract. The impact of air pollution on human health and the associated external costs in Europe United States (US) for year 2010 are modeled by a multi-model ensemble regional models frame third phase Air Quality Modelling Evaluation International Initiative (AQMEII3). surface concentrations O3, CO, SO2 PM2.5 used as input to Economic Valuation Pollution (EVA) system calculate resulting impacts from each individual model. Along with base case simulation, additional runs were performed...
Abstract. Through the comparison of several regional-scale chemistry transport modeling systems that simulate meteorology and air quality over European North American continents, this study aims at (i) apportioning error to responsible processes using timescale analysis, (ii) helping detect causes model error, (iii) identifying temporal scales most urgently requiring dedicated investigations. The analysis is conducted within framework third phase Air Quality Model Evaluation International...

Monovalent dimers of concanavalin A (Con A) have been prepared by a combination succinylation and photoaffinity labeling. Partial derivatization native Con using the label, p-azidophenyl-alpha-D-mannopyranoside, followed affinity chromatography yielded fraction that consisted with single saccharide-binding site at pH 5. These monovalent formed divalent tetramers 7. In order to achieve dimer this pH, were succinylated previously developed methods. Ultracentrifugation, equilibrium dialysis,...
Abstract Ochre sediments from acid mine drainage in Cornwall have been investigated using X-ray diffraction, thermal methods, infrared spectroscopy, photoelectron transmission electron microscopy and chemical methods order to determine their mineralogical composition. Fresh consist of ferrihydrite goethite. Large fractions these minerals are dissolved by the ammonium oxalate treatment reflecting poorly crystalline structure. contain large amounts surface-adsorbed SO 4 (up 9.3%) which is...

Abstract. In this study we introduce a hybrid ensemble consisting of air quality models operating at both the global and regional scale. The work is motivated by fact that these different types treat specific portions atmospheric spectrum with levels detail, it hypothesized their combination can generate an performs better than mono-scale ensembles. A detailed analysis carried out in attempt to investigate hypothesis determine real benefit produces compared ensembles constructed from only...
Abstract UK emissions of sulphur dioxide decreased by 94% between 1970 and 2010 are projected to decrease another 50% 2020 as coal fired power stations decommissioned. We used the Community Multiscale Air Quality model create maps (S) deposition assess impact these forecast decreases in S on net crops England Wales. Currently, average deposition, leaching, varies little regions, being greatest Yorkshire Humberside (Y&H), at ca. 5–6 kg/ha S, least Wales, 3–4 S. However, even Y&H is no...

Mixing of native concanavalin A (Con A) and its dimeric succinylated derivative (succinyl-Con in glycine-HCl buffer, pH 4.5, resulted the formation a new chemical species that could be separated as unique fraction by DEAE-cellulose chromatography or gel electrophoresis. The molecular weight this component, which contained subunits (Mr= 26,000) Con succinyl equimolar amounts, was 50,000 at both 5 7. These data suggest subunit exchange between 2 chemically distinct molecules yields hybrid...
