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...
This study assessed inhalation exposure to particulate matter (PM₁)-bound mercury (Hgp) and PM₁-bound polycyclic aromatic hydrocarbons (PAHs) among university students. For this purpose, simultaneous indoor (I) and outdoor (O) measurements were taken from two Polish technical universities (in Gliwice and Warsaw) located in distinct areas with respect to ambient concentrations and major sources ...
فرضیه: هدف این پژوهش، رطوبتزدایی جریان گاز با یکی از جدیدترین روشهای جداسازی است. فرایندهای مختلفی برای رطوبتزدایی پیشنهاد شده است که از آن جمله میتوان به استفاده از مایع جاذب و فرایند جذب سطحی اشاره کرد که فرایند اول بهدلیل هزینههای سرمایهگذاری و عملیاتی کمتر، بیشتر مورد توجه قرار گرفته است.روشها: دو عدد ماژول تماسدهنده غشایی الیاف توخالی برای ر...
Particulate matter is defined as a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. Such elements are currently measured utilizing air quality monitoring devices that provide information on PM 10 and PM 2.5 levels giving information on pollution levels. However, many difficulties are encountered in the determination of nanosized ...
