weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...

In order to evaluate the effects of sowing date and intra rows spacing on yield, yield components and some phytochemical characteristics in Roselle, a field experiment was conducted as a split plot layout based on randomized complete block design with three replications in 2013 and 2014 growing seasons. Five sowing dates were considered as the main plots (11th and 30th of March, 14th of April, ...

The energy performance of radiant slab cooling relative to conventional air systems to be clarified for climates from cold and dry to very hot and humid. EnergyPlus simulations were used to compare the energy performance of 1) radiant slab cooling combined with a dedicated outdoor air system and 2) a variable air volume system. Simulation results show that the radiant slab system provided 10% t...

The Dry Valleys are subdivided into three microclimate zones on the basis of summertime measurements of atmospheric temperature, soil moisture, relative humidity and wind-speed/ direction. Subtle variations in these climate parameters result in considerable differences in process geomorphology and in the development of unique landforms within each zone. The mapped zones include a coastal thaw z...

classification and utilization of lands based on their capability are necessary for sustainable land use management. the purpose of this study was to identify and grade the effective qualities on the rainfed farming in the roin area, north khorasan province, during the year of 2011. based on field observations and literature review the land qualities including climate, rooting conditions, moist...
