Sunshine hours are the only long term, reliable and available measured information that can be used to reach highly accurate estimates of solar radiation values on the Earth surface. In this paper the sunshine duration is used to estimate monthly average daily solar radiation on a horizontal surface, it can be used to predict solar radiation in different climatic region of Iran. According to th...

This study examined the effect of weather and seasonality on hipfracture incidence in older adults residing in New York City. A total off 66,346 patients aged > or = 65 years who sustained a fracture of the femoralneck or intertrochanteric region from 1985 to 1996 comprised the study population. Hip fractures were more likely to occur in the winter than in any of the other seasons (P<.001). Fac...

Walnut trees, as well their fruits, represent an important sector of the agricultural industry and cultivation significantly contributes to global economy. Irrigation is a key factor in walnut most problem related accurately estimating need for irrigation water. water use was estimated this study through artificial intelligence methods Artificial Neural Networks (ANNs) Adaptive Neuro-Fuzzy Infe...

In most of England and Wales the incidence of malignant melanoma of the skin has risen rapidly in recent years, especially in women. Mean incidences in the 14 English health regions and Wales correlated negatively with latitude and positively with hours of sunshine, suggesting that exposure to sunshine was an important causal factor. Male and female incidences within a region tended to show sim...

BACKGROUND Several retrospective studies have evaluated seasonal variations in the outcome of IVF treatment. Some also included weather conditions, mostly temperature and hours of daylight. The results were conflicting. METHODS In a retrospective study we analysed all fresh cycles (N = 9865) that were started between January 1, 2007 and December 31, 2012. Because some patients were included m...

Sunshine can have a profound impact on the systematic change in climate elements, such as temperature and wind speed, and in turn affects many aspects of the human society. In recent years, there has been a substantial interest in the variation of sunshine duration due to the dramatic global climate change. Hence, there is a need to better understand the variation of sunshine duration in order ...
