The radiation environment in deep space, where astronauts are behind the shelter provided by the Earth’s magnetosphere, is a major health concern. Galactic cosmic rays (GCR) and solar particle events (SPE) are two basic sources of space radiation in the solar system. The health risks of exposure to high levels of space radiation can be observed either as acute and delayed effects. Zhang et al. ...
nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...
UNLABELLED The aim of this work was to assess ultrafine particles (UFP) number concentrations in different microenvironments of Portuguese preschools and to estimate the respective exposure doses of UFP for 3-5-year-old children (in comparison with adults). UFP were sampled both indoors and outdoors in two urban (US1, US2) and one rural (RS1) preschool located in north of Portugal for 31 days. ...
This paper presents an attempt to create synthetic weather data for stochastic building simulation. The synthetic data are created entirely from the freely available Typical Meteorological Year (TMY) weather files using time series models and resampling. The generated data turn out to be representative of recorded data for our case study without any prior ‘knowledge’ of the long term distributi...
در این پژوهش کاربرد تصاویر ماهواره¬ای و gis در امکان سنجی استفاده از انرژی خورشیدی برای مناطق دور از منابع انرژی به منظور تأمین انرژی پایگاه¬های امداد و نجات جاده¬ای اتوبان زنجان – تبریز با استفاده از سامانه های فتوولتائیک با دو روش مختلف سنجش از دور و gis محاسبه گردید و سپس اقدام به اعتبارسنجی مقادیر به دست آمده با روش های تجربی شد. از داده های طیفی سنجنده oli و داده¬های حرارتی سنجنده tirs ماه...
Humidity is an indoor environmental factor that can affect thermal comfort inside a building. Sustainable construction techniques to create and maintain healthy indoor condition, based on ecological principles and through an efficient use of resources are the requirement nowadays. Common cause of moisture during the hot season is excessive indoor humidity, caused by an improper balance between ...
Keeping in view the conservation of natural resources, the power generation from the solar photovoltaic system is increasing day by day to meet the demand of energy worldwide. There are constraints of availability of space for ground mounted solar PV system for large installations. In some countries water bodies are being utilized to install solar PV system to reduce land use. Few floating syst...
BACKGROUND Ecological studies have reported possible effects of sunlight on the risk of several diseases. Little evidence is available on the association between mortality and solar and artificial UV exposure by individual level from prospective studies. METHODS The Swedish Women's Lifestyle and Health cohort study included women aged 30 to 49 years in 1991-1992. Participants completed a ques...
Challenging environmental conditions, including heat and humidity, cold, and altitude, pose particular risks to the health of Olympic and other high-level athletes. As a further commitment to athlete safety, the International Olympic Committee (IOC) Medical Commission convened a panel of experts to review the scientific evidence base, reach consensus, and underscore practical safety guidelines ...
