The environmental temperature has increased significantly reaching 33oC as felt by the community, one of which is in the Aceh region which triggers Global Warming. As a result of the increase in temperature in the Aceh area, many buildings and houses become uncomfortable especially during the daytime because most house with zinc roof. This will cause the temperature in the house and the air around it to increase. Therefore, it is necessary to do research on the study of heat absorption on colored zinc roofs. This research method is to calculate the heat absorption (sun intensity) in zinc that has been coated with several kinds of colors such as white, red, blue, yellow and black. The purpose of this study was to determine the color that has the least amount of heat absorption to the sun's intensity. The highest room temperature on zinc-coated black is 49.2° C and the lowest is in white.  40.9°C from the pen. In the environmental temperature observation, there is the highest temperature at 12.00.  Room temperature increased the highest temperature at 12.00 on black zinc.  The distribution of room temperature can be averaged with a yellow color of 46.0°C, a black color of 49.2°C, a blue of 45.5°C and a white zinc of 40.9 oC.  The heat absorbed in the room is 47.9 joules, so from the overall average of the test it can be described that the room temperature is 45.6 and the zinc temperature is 53.8oC from the highest temperature difference at 12.00 WIB, room temperature and 13.00 WIB the highest absorption occurs at zinc temperature.

Environmental Temperatures

Cold environmental temperatures during exercise and recovery alter the acute response to cellular signaling and training adaptations. Approximately 3 wk is required for cold temperature acclimation to occur. To determine the impact of cold environmental temperature on training adaptations, fitness measurements, and aerobic performance, two groups of 12 untrained male subjects completed 1 h of cycling in 16 temperature acclimation sessions in either a 7°C or 20°C environmental temperature. Fitness assessments before and after acclimation occurred at standard room temperature. Muscle biopsies were taken from the vastus lateralis muscle before and after training to assess molecular markers related to mitochondrial development. Peroxisome proliferator-activated receptor-γ coactivator 1α ( PGC-1α) mRNA was higher in 7°C than in 20°C in response to acute exercise before training ( P = 0.012) but not after training ( P = 0.813). PGC-1α mRNA was lower after training ( P < 0.001). BNIP3 was lower after training in the 7°C than in the 20°C group ( P = 0.017) but not before training ( P = 0.549). No other differences occurred between temperature groups in VEGF, ERRα, NRF1, NRF2, TFAM, PINK1, Parkin, or BNIP3L mRNAs ( P > 0.05). PGC-1α protein and mtDNA were not different before training, after training, or between temperatures ( P > 0.05). Cycling power increased during the daily training ( P < 0.001) but was not different between temperatures ( P = 0.169). V̇o2peak increased with training ( P < 0.001) but was not different between temperature groups ( P = 0.460). These data indicate that a 3-wk period of acclimation/training in cold environmental temperatures alters PGC-1α gene expression acutely but this difference is not manifested in a greater increase in V̇o2peak and is dissipated as acclimation takes place. NEW & NOTEWORTHY This study examines the adaptive response of cellular signaling during exercise in cold environmental temperatures. We demonstrate that peroxisome proliferator-activated receptor-γ coactivator 1α mRNA is different between cold and room temperature environments before training but after training this difference no longer exists. This initial difference in transcriptional response between temperatures does not lead to differences in performance measures or increases in protein or mitochondria.

Carotene and vitamin A metabolism in the rat were studied at two environmental temperatures. The utilization of carotene is greater in animals maintained at a low environmental temperature (2°) than at room temperature (22°). This occurred within a period of 3 days. Both the hepatic storage and the rate of metabolism of orally administered vitamin A were unaffected by environmental temperature. The response of Wistar and Sprague–Dawley strains was similar.

A suitable long-term anaesthetic technique was required for implantation of physiological sensors and telemetric devices in sub-adult Nile crocodiles (Crocodylus niloticus) to allow the collection of physiological data. Five Nile crocodiles with a median body mass of 24 kg were used. After manual capture, they were blindfolded and 0.2 mL (1 mg/mL) medetomidine was administered intramuscularly in four of the animals which had an estimated body mass between 20 kg and 30 kg. One crocodile with an estimated body mass of 50 kg received 0.5 mL. For induction, 5 mL propofol (10 mg/mL) was injected intravenously into the occipital sinus. Additional doses were given when required to ensure adequate anaesthesia. Anaesthesia was maintained with 1.5% isoflurane. Ventilation was controlled. Local anaesthesia was administered for surgical incision and external placement of the radio transmitter. Medetomidine was antagonised with atipamezole at the end of surgery. Median heart rate during surgery was 22 beats/min, at extubation 32 beats per min and 30 beats per min the following day at the same body temperature as under anaesthesia. Median body temperature of the animals increased from 27.3 °C to 27.9 °C during anaesthesia, as room temperature increased from 24.5 °C to 29.0 °C during surgery. Anaesthesia was successfully induced with intramuscular medetomidine and intravenous propofol and was maintained with isoflurane for the placement of telemetric implants. Intraoperative analgesia was supplemented with lidocaine infiltration. Perioperative physiological parameters remained stable and within acceptable clinical limits. Multiple factors appear to influence these variables during the recovery period, including residual anaesthetic effects, environmental temperature and physical activity.

Further observations are described on the measurement of the incorporation of inorganic phosphate labelled with P32 into the inorganic phosphate of the adrenal gland to assess the immediate pituitary–adrenal response when cold acclimatized and non-acclimatized rats are exposed to more severe cold (2 hours at −5 °C). In rats acclimatized to cold by conditioning to 3 °C for 4 weeks, this immediate pituitary–adrenal response was considerably less than that in non-acclimatized rats maintained at room temperature (22 °C). The reduction in the immediate pituitary–adrenal response took 3 to 4 weeks to develop and persisted for 12 hours, but not for 4 days. Rats that were conditioned to −5 °C by exposures for 2 or 6 hours daily for 4 weeks showed no reduction in the immediate pituitary–adrenal response to more severe cold, but there was a significant decrease in this response in rats conditioned for 6 hours daily for 8 weeks.Rats acclimatized to cold by conditioning to 3 °C for 4 weeks showed greater survival when exposed to an environmental temperature of −15 °C than rats conditioned to 22 °C. Rats that were conditioned to −5 °C for brief daily periods (2 hours or 6 hours) for 4 weeks or 8 weeks also survived exposure to severe cold (−22 °C) better than rats maintained at room temperature.In general, significant increases in adrenal weight were found in those cold-conditioned rats that showed a reduced pituitary–adrenal response. However, it is concluded that the development of increased survival on exposure to severe cold, by a process of conditioning to less severe cold, is not necessarily accompanied by a reduction in the immediate pituitary–adrenal response to severe cold, or by an increase in weight of the adrenal glands.
