Most existing methods of human attribute recognition are part-based, where features are extracted at human body parts corresponding to each human attribute and the part-based features are then fed to classifiers individually or together for recognizing human attributes. The performance of these methods is highly dependent on the accuracy of body-part detection, which is a well known challenging...

I. Eight groups each of four castrated male pigs, 25-30 kg initial body-weight, were kept for periods of 3 weeks in a calorimeter equipped as a pig pen and maintained at either 8" or zoo. At each temperature two feeding levels (g food/kg body-weight per d) were used, 45 and 52 at So, and 39 and 45 at 20'. Metabolizable energy, heat loss and nitrogen balance were measured. 2. Heat loss was highe...

Hypothermia during general anesthesia develops with a characteristic three-phase pattern. The initial rapid reduction in core temperature after induction of anesthesia results from an internal redistribution of body heat. Redistribution results because anesthetics inhibit the tonic vasoconstriction that normally maintains a large core-to-peripheral temperature gradient. Core temperature then de...

The influence of head position on thermal stress was assessed by using a heavily clothed thermal mannequin in three different body positions [supine, face straight up (FSU); supine, face to the side (FTS); prone, FTS] and with or without the head covered by a bonnet. The mannequin was exposed to air temperatures of 29, 32, 34, and 36 degrees C. When the head is uncovered, body or head position ...

Information on cloacae temperature (CT), heart rate (HR), Isoflurane use, and oxygen flow was collected during field implantation of Platform Terminal Transmitters (PTT-) 100 satellite transmitters in Greenland sea birds. Information was obtained from 14 intracoelomic and 5 subcutaneous implantations in thick-billed murres (Uria lomvia) and 9 intracoelomic implantations in common eiders (Somate...

Progressively increasing heat stress ultimately results in heat stroke, a medical emergency leading to death if not treated properly. Initially in heat stress, enormous increases in blood flow and volume in skin (and muscle if exercising) are achieved by the diversion of blood away from the splanchnic bed, kidneys, and probably fat and muscle, and in some species such as man, there is also an i...

Mouse lines divergently selected for heat loss were evaluated for correlated responses in the hypothalamic transcriptome. High (MH) heat loss mice have approximately 50% greater heat loss, approximately 35% less body fat, approximately 20% greater feed intake, approximately 100% greater locomotor activity levels, and higher core body temperature compared with low (ML) heat loss mice. We evaluat...

The temperature of the human skin is the resultant of two influences;--the heat brought to the skin by the blood stream and the heat loss from the skin surface. Any alteration in either one of these factors serves to produce a change in skin temperature. Therefore, under given environmental conditions, the skin temperature at a particular time and place is a measure of the change in the amount ...

Within the scope of the European research initiative THERMPROTECT numerous thermal manikin experiments were performed on the transfer of heat through personal protective clothing (PPC) under far infrared radiation (FIR) stress. The influence of the reflectivity and insulation of the clothing, the radiated body surface area, and the interaction with convection and wet underwear were considered. ...

We examined if an exercise-heat acclimation program improves body fluid regulatory function in older subjects, as has been reported in younger subjects. Nine older (Old; 70 ± 3 yr) and six younger (Young; 25 ± 3 yr) male subjects participated in the study. Body fluid regulatory responses to an acute thermal dehydration challenge were examined before and after the 6-day acclimation session. Acut...
