New energy technologies, along with the benefits, are associated with challenges and Difficulties. Geothermal energy as one of the renewable energies is a clean and sustainable energy source, yet its development still has some impact on the environment such as: greenhouse gas emissions, noise pollution, surface and groundwater contamination, subsidence, and seismicity. This paper provides a bri...
سابقه و هدف: امفالیت یا التهاب و عفونت نسج نرم اطراف ناف یکی از بیماریهای مهم دوران نوزادی است که با خطر بروز سپتی سمی، پریتونیت و عفونت ارگانهای داخلی به دلیل آمبولیهای سپتیک همراه است. جهت بررسی تاثیر استفاده و یا عدم استفاده از الکل (clean cord care) در مراقبت از بندناف نوزادان، مطالعه ای در زایشگاه شهید فیاض بخش کرج در ماههای مرداد تا بهمن 1378 به عمل آوردیم. مواد و روشها: مطالعه حاضر به صو...
In atmospheric chemistry, interactions between air pollution, the biosphere and human health, often through reaction mixtures from both natural and anthropogenic sources, are of growing interest. Massive pollution emissions in the Anthropocene have transformed atmospheric composition to the extent that biogeochemical cycles, air quality and climate have changed globally and partly profoundly. I...
The need for a device to sample large areas that are lightly contaminated with microorganisms motivated the development of the vacuum probe. The intended use of the instrument is to sample clean surfaces in laminar flow clean rooms, but the device could be used for sampling surfaces in other clean environments. Such a device was designed, fabricated, and tested at Sandia Laboratories, Albuquerq...
