Radiant heating/cooling systems are thermally efficient and economically feasible alternatives to conventional ventilated air conditioning. This study experimentally investigates the thermal performance of ceiling radiant cooling panel (CRCP) with a segmented concave surface by evaluating conditions inside laboratory-scale room equipped this new panel. The experiments were carried out under var...

Laser therapy for cutaneous hypervascular malformations such as port-wine stain birthmarks is currently not feasible for dark-skinned individuals. We study the effects of pulse duration, radiant exposure, and cryogen spray cooling (CSC) on the thermal response of skin, using a Monte Carlo based optical-thermal model. Thermal injury to the epidermis decreases with increasing pulse duration durin...

Radiant floor systems offer significant potential for studying and developing energy flexibility strategies buildings their interaction with smart grids. Efficient design operation of such require several critical decisions on control variables to maintain comfortable thermal conditions in the space surface temperatures within recommended range. This study presents a comparison different activa...

Breath and ambient (room) carbon monoxide (CO) levels were measured in a random sample of 168 adults in their own homes. The levels of breath CO in the 69 smokers ranged from 3 ppm to over 100 ppm, 74% being above 10 ppm; mean levels in the 99 nonsmokers were lower than in the smokers, 79% being below 6 ppm. In the remaining 21% of nonsmokers with higher breath levels than expected, the ambient...

Thomas, J. B., Conner, R. L. and Graf, R. J. 2012. Radiant hard red winter wheat. Can. J. Plant Sci. 92: 169 175. Radiant hard red winter wheat (Triticum aestivum L.) is well adapted to the non-hazard region for stem rust (Puccinia graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.) within the Canadian prairies. Based on evaluation relative to Norstar, CDC Osprey, AC Tempest and AC Bellatri...

We present a comprehensive study of a possible α-Cygnid meteor shower. Based on visual and telescopic observations made by Polish observers we estimate basic parameters of the stream. Activity of α-Cygnids lasts from around June 30 to July 31 with clear maximum near July 18 (solar longitude λ = 116.5◦). Maximal Zenithal Hourly Rates (ZHRs) are equal to 3.6± 1.2. The structure of the radiant ana...

Several studies suggest that welding is detrimental to the male reproductive system. Welding fume and radiant heat are of interest as possible causal factors. This study investigates semen quality and sex hormone concentrations among 17 manual metal arc alloyed steel welders with a moderate exposure to radiant heat (globe temperature ranging from 31.1 degrees to 44.8 degrees C), but without sub...

The article focuses on the description of an innovative solution and application active thermal protection buildings using insulation panels with regulation heat transfer in form a contact system. are part prefabricated lightweight outer shell, which together low-temperature heating high-temperature cooling system creates indoor environment. energy source is usually renewable sources or technol...
