Knowledge, Attitude and Practices Regarding Extreme Environments and Cold Adaptation at Extreme Altitudes on the Himalayan Ranges
Introduction: Extreme-altitudes (5500 m/18045 ft and higher) pose environmental, psychophysiological, infrastructural, logistic, and ergonomic challenges that question explorer’s adaptability and mission-efficiency due to isolation, monotony, intimidating environment and terse health conditions. The assessment of an explorer’s comprehensive adaptability in extreme-altitudes is ...
متن کاملResistance of Bacillus endospores to extreme terrestrial and extraterrestrial environments.
Endospores of Bacillus spp., especially Bacillus subtilis, have served as experimental models for exploring the molecular mechanisms underlying the incredible longevity of spores and their resistance to environmental insults. In this review we summarize the molecular laboratory model of spore resistance mechanisms and attempt to use the model as a basis for exploration of the resistance of spor...
متن کاملPhysiological Components and Physical Combat Readiness in Warm, Cold, and High Altitude Extreme Environmental Conditions: Narrative Review
Military forces based on their mission have to deployment and executed military operation in extreme environmental conditions, they simultaneously experience nutritional and sleep disorders and endure mental stress. This condition plays essential role in body hemostasis, military fitness components and finally commanded mission's success. Neglecting above mentioned condition physiological respo...
متن کاملExtreme alien light allows survival of terrestrial bacteria
Photosynthetic organisms provide a crucial coupling between the Sun's energy and metabolic processes supporting life on Earth. Searches for extraterrestrial life focus on seeking planets with similar incident light intensities and environments. However the impact of abnormal photon arrival times has not been considered. Here we present the counterintuitive result that broad classes of extreme a...
متن کاملImproving photovoltaic performance through radiative cooling in both terrestrial and extraterrestrial environments.
The method of detailed balance, introduced by Shockley and Queisser, is often used to find an upper theoretical limit for the efficiency of semiconductor pn-junction based photovoltaics. Typically the solar cell is assumed to be at an ambient temperature of 300 K. In this paper, we describe and analyze the use of radiative cooling techniques to lower the solar cell temperature below the ambient...
