Occupant behavior has a significant impact on building energy performance. The purpose of this paper is to quantify the stochastic characteristics of manual solar shades and their influence on building energy performance. A co-simulation for occupants’ stochastic control of manual solar shades was conducted and the statistic indicators (non-parameter tests and autocorrelation function) were cal...

introduction climate has always been one the main factors of designing urban spaces in iran since past centuries. by analyzing urban spaces it can be concluded that different cities have different urban spaces due to climate differences. one of the main reasons of the differences in the type and orientation of urban spaces is the climate as one of the key factors in designing these areas. regar...

ABSTRACT: Key Words: Acute myocardial Infarction season, cold, mortality We studied 395 consecutive patients with acute myocardial infarction ,admitted to Poor -sina Hospital Rasht , Iran ,over two years(during the period 1-1-61 to 29-12-62), and correlated the incidence of the disease inhospital mortality and 10-year posthospital mortality and with seasons. There was no seasonal variation i...

Human mortality is closely related to natural climate-determined levels of thermal environmental stress and the resulting thermophysiological strain. Most climate-mortality research has focused on seasonal extremes during winter and summer when mortality is the highest, while relatively little attention has been paid to mortality during the transitional seasons of autumn and spring. The body ac...

This study was carried out to determine heart rate (HR) values, including diurnal, seasonal, and sex patterns, in the African giant rat (Cricetomys gambianus, Waterhouse). HR was measured using stethoscope in grip-restrained African giant rats of either sex (103 bucks and 98 does), live-trapped from a tropical Savannah, and caged individually in the laboratory during the harmattan (cold-dry), h...

Physiol. 215(2) : 439-443. 1968.-The stimulating effect of antidiuretic hormone (ADH) on Na transport across isolated frog skin (Runa temporuriu) was studied monthly, along with the glycogen contents of liver and muscle. ADH induced a sust...

Aerosol optical depth in 550 nm and angstrom exponent measurements with MODIS have been studied with 1-degree resolution for the period 2006-2017 in the middle east. Moreover, tropospheric aerosol optical depth and depolarization ratios measured at 532 nm with CALIOP have been studied for same area and same period of time too. These parameters have been classified seasonally. Optical depth resu...
