Clothing as solar radiation protection.
The sun is essential for life. Yet, sunlight can also be a source of such deleterious effects as sunburn, and suntanning, as well as premalignant and malignant lesions. These may all occur in individuals with normal responses to sunlight. In addition, there exist a variety of 'abnormal' photosensitivity responses to sunlight that may result from either endogenous imbalances (e.g. the porphyrias...
متن کاملBest Orientation Determination of Buildings in Zanjan City Based on Solar Radiation
In recent years, high consumption of energy has become one of the major problems of world, especially in big cities. One of the solutions given for this situation is using solar energy as much as possible. If buildings are constructed in accordance with solar radiation and regional climate, they can absorb the lowest energy in hot and the most energy in cold periods; there will then be noticeab...

متن کاملEconomic assessment of renewable power generation based on wind speed and solar radiation in urban regions
Economic evaluation of 12 MW grid-connected wind farms and PV power plants in two regions in Northern Cyprus for electricity generation was investigated. The wind speed, sunshine duration, and solar global radiation characteristics were analyzed using monthly data collected over 17 years (2000-2016) for Girne and nine years (2008-2016) for Lefkoşa, which were measured at various heights. The re...
متن کاملGarments as solar ultraviolet radiation screening materials.
Although wearing clothing to protect one's skin from the harmful rays of the sun is not new practice, this practice is of recent increasing interest. This article discusses 1) three types of protection (sunburn, precancerous skin lesion development, and photoaging) that can be realized by covering the skin with fabric, 2) the process by which some garments come to be labeled with information ab...
