Abstract This study focuses on exploring the impact of urban forms and vegetation combination patterns microclimate in a complex environment. Results shown that closed form has higher air temperature resulting pedestrians are easier to feel heat stress; instead, open usually wind speed. Vegetation can effectively reduce speed while reducing change rate mean radiant temperature. However, effect ...

The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...

The radiant time series method is a new method for performing design cooling load calculations, derived from the heat balance method. It effectively replaces all other simplified (non-heat-balance) methods such as the cool#zg load temperature difference~solar cooling load~cooling load factor method (CLTD/SCL/CLF), the total equivalent temperature difference~time averaging method (TETD/TA), and ...

temperature is considered as the basic element of climate and also the environmental limiting factor in lutdesert. in this research, in order to identify the temperature of lut desert located in east of central iran, using remote sensing data, six series of modis sensor images related to june 24th & december 23rd 2002, and also january 22nd, march 22nd, june 22nd & september 24th 2003 w...

the paper presents results of experimental studies on the methane and propane ignition process in various volumetric compositions of oxidizers heated to temperatures higher than ignition point of analyzed fuels (htac conditions–high temperature air combustion conditions). the increment of temperature dt and the ignition delay time tig are parameters characterizing the process of ignition under ...

Frost is one of the atmospheric phenomena which seriously threaten crop production. It also causes numerousaccidents in mountainous roads. In this research the Spatial Synoptic Classification SSC method was employed toclassify the type of air masses. For the classification, such meteorological data as: temperature, dew point, mean sealevel pressure, cloudiness, direction and speed of wind were ...
