Land Use Regression (LUR) models have been used increasingly for modeling small-scale spatial variation in air pollution concentrations and estimating individual exposure for participants of cohort studies. Within the ESCAPE project, concentrations of PM(2.5), PM(2.5) absorbance, PM(10), and PM(coarse) were measured in 20 European study areas at 20 sites per area. GIS-derived predictor variable...
back ground and purpose: air pollution in cities thorough the world, is a complex mixture of poisonous compounds which are always combustion products particulate matters (pm) are instant member of this mixture. despite wide spectrum health effects of pm, effects on death seem to be the most important one. the main purpose of this study was to estimate number of cardio pulmonary death in adults ...
background: air pollution has been a serious public health threat worldwide. it has been linked to pulmonary and cardiovascular diseases but is also believed to contribute to air-pollution-mediated cardiometabolic disease such as diabetes. we investigated the relationship between type 2 diabetes mellitus (dm2) and air pollution in densely developed urban settings in south korea, using national ...
background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...
Introduction: Nephropathy is defined as rational loss of renal function related with glomerulosclerosis and declining glomerular filtration rate. Inflammation and oxidative stress play a critical role in nephropathy. Plantago major has antioxidant effects. The aim of present study is the investigation of the effect of Plantago major hydro-alcoholic extract on the oxidative stress and renal func...
background : in recent years, due to its distinct geographical circumstances and position in a gorge, and accumulation of pollutants in surface air, isfahan, iran has become one of the most polluted cities in the iran in terms of air pollution. the purpose of this study was to estimate cardiovascular and respiratory diseases attributed to particulate matter of less than 10 microns (pm 10 ) in i...
Abstract The period–luminosity relations (PLRs) of Milky Way δ Scuti ( Sct) stars have been described to the present day by a linear relation. However, when studying extragalactic systems such as Magellanic Clouds and several dwarf galaxies, we notice for first time nonlinear behavior in PLR Sct stars. Using largest sample ∼3700 from data available literature—mainly based on Optical Gravitation...
