Algeria has one of the highest solar deposits in world, average duration sunshine Algerian Sahara is 3500 hours, and this potential can be an important factor for sustainable development region, if it exploited economical way. In context, should noted that city Adrar located region "solar belt", which enjoys abundant more than 3000 hours per year, based on data from Overall hourly irradiation a...

Therefore, we tried evaluate the differences in associations between environmental and epistaxis children of different ages. Methods A total 20,234 patients who visited hospital January 1, 2002, December 31, 2015, were enrolled s...

In this chapter four combinations of input features and the feedforward, cascade forward and recurrent architectures are compared for the task of forecast tourism time series. The input features of the ANNs consist in the combination of the previous 12 months, the index time modeled by two nodes used to the year and month and one input with the daily hours of sunshine (insolation duration). The...

Weather, in particular the intensity and duration of sunshine (luminance), has been shown to significantly affect financial markets. Yet, because of the complexity of market interactions we do not know how human behavior is affected by luminance in a way that could inform theoretical choice models. In this paper, we use data from a field study using an incentive-compatible, decision task conduc...

BACKGROUND AND OBJECTIVE Several studies have shown wide prevalence of vitamin D deficiency with serum 25(OH)D <49.9 nmol/L in urban Indians related to their poor sunshine exposure and skin pigmentation. However, there is limited information in rural Indians. We hypothesized presence of higher 25(OH)D in rural subjects as compared to urban because of farming related abundant sunshine exposure. ...
