A new inverse method is proposed for estimation of thermal inertia and heat gain in air conditioning and refrigeration systems using on-site temperature measurements. The method is applied on a walk-in freezer room of a restaurant in Surrey, British Columbia, Canada during one week of its regular operation. The thermal inertia and instantaneous heat gain are calculated and the results are valid...

The rewarming benefit of anterior torso heat pad application in mildly hypothermic conscious adult trauma patients remains inconclusive in this randomized comparative clinical trial. There was no between-group rewarming gain in ear canal temperature when an anterior torso chemical heat pad was compared with blankets. Patient awareness, and favorable perception of, being administered the active ...

The transfer of heat radiation through clothing (Bröde et al., 2005; Clark & Cena, 1978; Lotens & Pieters, 1995) and the effects of moisture in different clothing layers (Bröde et al., 2008a; Havenith et al., 2008; Richards et al., 2008) have been studied separately. Also models predicting the heat gain from radiation (den Hartog et al., 2007; Lotens & Pieters, 1995) or the heat loss with wet c...

this study was conducted to investigate the effects of different levels of zinc sulfate and chromium picolinate on the performance, immune response and meat quality of japanese quails under heat stress condition. the birds (n = 540; 7-d-old) were randomly assigned to 9 treatment groups consisting of 3 replicates of 20 birds each in a 3 × 3 factorial arrangement of treatments [zinc (0, 40, 80 mg...

To reduce heat in commercial buildings daylight, you can use shades, blinds, and curtains. On hot days, draw the curtains or shades to keep sun out. Well-designed control shading devices dramatically building peak gain cooling requirements improve natural lighting quality of interiors. Depending on amount location fenestration, reductions annual energy consumption 5% 15% have been reported. Hor...

Performance was evaluated for a passive solar space heating system utilizing heat pipes to transfer heat through an insulated wall from an absorber outside the building to a storage tank inside the building. The one-directional, thermal diode heat transfer effect of heat pipes make them ideal for passive solar applications. Gains by the heat pipe are not lost during cloud cover or periods of lo...

The effects of dietary high levels of heat treated locally produced flaxseeds on body weight gain, and immune response were evaluated using local Saudi chicken during the pre-laying period (17-23 wk). Diets were formulated included locally produced heat treated flaxseed roasted at 60 ̊C for 5 minutes to have 5 dietary levels 0, 10, 20, 30, and 40 % of flaxseed. Each diet was fed to 50 experiment...

Both whole body heat stress and stimulation of muscle metabolic receptors activate muscle sympathetic nerve activity (MSNA) through nonbaroreflex pathways. In addition to stimulating muscle metaboreceptors, exercise has the potential to increase internal temperature. Although we and others report that passive whole body heating does not alter the gain of the arterial baroreflex, it is unknown w...
