Urine osmolality was studied in 38 babies nursed in conventional incubators or cots and 18 nursed under an overhead radiant heat shield. Among 50 babies receiving a similar fluid intake in the first 48 hours of life mean urinary osmolality was significantly higher in the radiant heater group. In babies weighing less than 1500 g a trend towards higher urinary osmolalities was recorded in those n...

Thermoreceptors provide animals with background information about the thermal environment, which is at least indirectly a prerequisite for thermoregulation and assists bloodsucking insects in the search for their host. Recordings from peg-in-pit sensilla and tapered hairs on the antennae of the bug Rhodnius prolixus revealed two physiologically different types of warm cells. Both types responde...

In this paper we proposed the novel air-conditioning system which combined induction ventilation and radiant air-conditioning. The indoor terminal device is the radiant induction-unit (RIDU). The RIDU is the induction unit combined with the pore radiant panel on which the copper pipes with rigid aluminum diffusion fins are installed. The two-stage evaporator chiller with the non-azeotropic mixt...

Crop farming systems in the Wimmera and Mallee region of Victoria are diverse. The environmental and economic conditions that prevail demand that farmers make constant changes and improvements to their farming systems. In this research the performances of four representative farming systems, designated ‘Reduced Till’, ‘Hungry Sheep’, ‘Fuel Burners’ and ‘No Till’, were examined and evaluated usi...

This paper studies the heating load and thermal comfort distribution in a typical office with a mixed radiant and convective heating system for two different locations of radiant heat sources. Accurately estimating the heating load in a mixed heating space requires careful consideration of the energy balance on each room surface and the comfort level in the space. A pure radiant heating system ...
