The effect of variations in land cover on mean radiant temperature (T mrt ) is explored through a simple scheme developed within the radiation model SOLWEIG. Outgoing longwave radiation is parameterised using surface temperature observations on a grass and an asphalt surface, whereas outgoing shortwave radiation is modelled through variations in albedo for the different surfaces. The influence ...

Intensive urbanization and global warming are impacting the health well-being of urban population. Nevertheless, environments with different designs will have micro local climate conditions. This study used data from micrometeorological measurements performed in spaces (downtown, park, riverside) Banja Luka, Bosnia Herzegovina, on hot summer days June 2021. Air temperature, relative humidity, w...

Radiative heat transfer has a significant effect on nitric oxide (NO) formation in turbulent non-premixed flames. Consequently, predictive models of turbulent non-premixed flames must include an accurate radiation submodel. To investigate the importance of radiation submodels in modeling NO formation, multiscalar measurements of temperature and species were coupled with radiation measurements i...

Mean Radiant Temperature (MRT) is a critical physical quantity that indicates how human beings experience radiation in their surrounding environment. If taken outdoors, MRT depends on the temperature of the sky, ground, vegetation and surrounding buildings, and is therefore difficult to predict reliably. An additional challenge for designers is that publically available simulation tools do not ...

mazafati date is a wet and semi-dried date fruit type with dark red to black color that has premier quality. because of its high moisture content, date fruits of this variety are very perishable at room temperature and therefore must be refrigerated during storage. in this study, effect of air temperature (50, 60, 70, 80 and 90 ˚c) and air flow rate (1, 1.5 and 2 m/s) in hot air drying of mazaf...

Spatially continuous satellite infrared temperature measurements are essential for understanding the consequences and drivers of change, at local and regional scales, especially in northern and alpine environments dominated by a complex cryosphere where in situ observations are scarce. We describe two methods for producing daily temperature fields using MODIS ―clear-sky‖ day-time Land Surface T...

Background & Aims of the Study: Heat Stress is a major factor in many industrials and heat stress is one of occupational hazards in the workplace and severely affects the health and productivity, heat stress can decrease efficiency, increase accidents and reduce safety levels. Aim of this study was comparing the heat stress indices of HSI and WBGT and core body temperature in steels ind...

AIMS To test the hypothesis that external radiant heating might lead to significant fluctuations in superficial and core head temperatures in newborn infants. METHODS In an observation group of 14 term infants nursed under a radiant heater, servo-controlled to the abdominal skin, changes in rectal, core head, and scalp temperatures with heater activation were examined. In a further interventi...

In this paper, an innovative hybrid condensing radiant tubes heating system for industrial building is modelled in three climatic zones of Italy using dynamic simulation software. Radiant are coupled with air–water heat pump, the latter serving air terminals located building. The energy performance optimized by evaluating best nominal power cut-off temperature a bivalent parallel operation, alt...

Piglets from birth to wean at 21 days of age were subjected to heat lamps with either constant power output (CO) of 175 W or variable power output (VO) from 175 W at birth to 100 W by weaning time. Each type of heat lamp had either clear or red radiant rays. The effects of lamp output and color on heat lamp usage (HLU) and average daily gain (ADG) of the piglets were examined for a cool air tem...
