In a previous paper Hey and Maurice (1968) have reported the effect of changes of relative humidity on the heat production and heat loss in normal naked babies in a specially constructed metabolic chamber under controlled environmental conditions. In order to evaluate the clinical relevance of these observations we have studied the control of relative humidity that could be achieved in three co...

A test specimen, comprising 100 iron wires of 1 mmφ diameter arranged in a 10 × matrix, was exposed to temperature cycling between 0°C and −20°C. NaCl solution (0.1 wt%) dropped on the surface form an ice droplet, coupling current each electrode against other 99 electrodes measured sequentially obtain map. The average varied with cycling. increased at relative humidity > 65% absence which simil...

knowledge of the warming or cooling effects induced by asphalt or grass covered areas, may improve our understanding of how thermal stress or thermal comfort is created for workers who have to work outdoors for long hours in warm seasons. for this purpose a field measurements were carried out to know the cooling and warming effects of two adjacent areas, one covered with grass and the other wit...

Hatchling painted turtles (Chrysemys picta) hibernate in their shallow natal nests where temperatures occasionally fall below -10 C during cold winters. Because the thermal limit of freeze tolerance in this species is approximately -4 C, hatchlings rely on supercooling to survive exposure to extreme cold. We investigated the influence of environmental ice nuclei on susceptibility to inoculative...

BACKGROUND Frozen storage often precedes metagenomic analysis of biological samples; however, the freezing process can have adverse effects on microbial composition. The effect of freezing on the detection of bacteria inhabiting the infant nasopharynx, a major reservoir of bacterial pathogens, was investigated. METHODS 16S ribosomal RNA (rRNA) gene-based terminal restriction fragment length p...

Because most shrinkage-reducing admixtures (SRAs) significantly reduce the surface tension of a cement paste pore solution, they will naturally influence all physical properties and processes that are dependent in some way on surface tension. Such properties include internal relative humidity, capillary stresses, and freezing point depression, all via the Kelvin equation and its variants (Kelvi...

Mass generation rates of ammonia, moisture, and heat production were measured for mice that were housed in standard shoebox cages at a density of five mice per cage and maintained in either a 35% or 75% room relative humidity. Two mouse strains kept on two different types of bedding materials were compared when bedding material had been in the cages for two, six, and ten days. Gas exchanges dir...

The use of proteins and peptides as human therapeutics has been increased in recent years. Lipase is a relatively homogeneous proteinaceous enzyme indicated in maldigestion. The purpose of the present study was to evaluate the effect of humidity along with compactional pressure on the enzymatic activity of wheat germ lipase. Samples of lipase powder were kept at different relative humidity (RH)...

The statistical feature of occurrence of multiple tropical cyclone (MTC) events in the western North Pacific (WNP) is examined during summer (June–September) for the period of 1979–2006. The number of MTC events ranged from one to eight per year, experiencing a marked interannual variation. The spatial distance between the TCs associated with MTC events is mostly less than 3000 km, which accoun...
