The performance of large-scale PV solar plant installed in sub-Saharan regions is affected by the deposition dust on surface modules. Frequent cleaning modules increases profitability plants. objective this study to determine optimal cycle a subjected wind loaded with sand and dust. This took place Senegal. measurement data are analysed for period two years used extract soiling rate. Optimizati...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract The formation and propagation of density currents are well studied processes in fluid dynamics with many applications to other science fields. In the atmosphere, density currents are usually meso-β/γ mechanisms and ar...

BACKGROUND In sublingual immunotherapy, optimal doses are a key factor for therapeutic outcomes. The aim of this study with tablets containing carbamylated monomeric house dust mite allergoids was to determine the most effective and safe dose. METHODS In this double-blind, placebo-controlled dose-finding study, 131 patients with house dust mite-induced allergic rhinoconjunctivitis were random...

iran is one of the world's arid regions and exposed to dust particles in the air. this is important in spatial and temporal terms as well as the affects human health. in this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. in the spatial and temporal analysis of dusty days 38 synoptic stations were studied. in order to conduct data...

PURPOSE To study the relationship between exposure to airborne particles in a pulp and paper mill and markers of inflammation and coagulation in blood. METHODS Personal sampling of inhalable dust was performed for 72 subjects working in a Swedish pulp and paper mill. Stationary measurements were used to study concentrations of total dust, respirable dust, PM10 and PM2.5, the particle surface ...

Values for total dust concentration in indoor air in day-care centres, offices and schools with no reported problems are measured. These are day-care centres 41 ± 14 μg/m

The Panoramic Cameras on NASA's Mars Exploration Rovers have each returned more than 17,000 images of their calibration targets. In order to make optimal use of this data set for reflectance calibration, a correction must be made for the presence of air fall dust. Here we present an improved dust correction procedure based on a two-layer scattering model, and we present a dust reflectance spect...
