For the purpose of improving living environment in chill region of China, reducing building energy consumption and carbon dioxide emissions, this paper studies general layout, shape, plane, and envelop of public buildings in depth, and puts forward corresponding design strategies on the basis of systematical analysis on geographical features, climate characteristics, economic level, technology ...

The objective of the present study was to define the risk and the time required to develop frostnip on the face during exposure to cold winds. Twelve subjects (6 males and 6 females) were exposed to sixteen 45 min tests where the wind intensity varied between 0, 16 and 32 km/h. The tests were conducted at 0, -10, -20, -30, -40 and –50°C (only 0 km/h wind was present at -50°C). During the tests,...

Many persons world wide are exposed to cold environments, either indoors for example in cold stores, or outdoors. Cold is a hazard to health and may affect safety and performance of work. Basis for the creation of safe and optimal working conditions may be obtained by the application of relevant international standards. ISO 11079 presents a method for evaluation of whole body heat balance. On t...

Chill and freeze represent very different components of low temperature stress. Whilst the principal mechanisms of tissue damage and of acquired protection from freeze-induced effects are reasonably well established, those for chill damage and protection are not. Non-freeze cold exposure (i.e. chill) can lead to serious disruption to normal life processes, including disruption to energy metabol...

[1] Dynamical behavior of the one minute resolution Polar Cap (PC) index was studied by using the 1995–2000 data sets. It was found that the probability distribution functions (PDFs) of the PC-index increments display a strong non-Gaussian shape in both positive and negative time intervals, depending on the time of an increment. This indicates that PC-index is not characterized by a global time...

The subject of this paper is the Colorado State University–University of Chicago–Illinois State Water Survey (CSU–CHILL) National Radar Facility’s S-band polarimetric research radar. Key features of this system include polarization agility (provided by the dual-transmitter, dual-receiver design), a recently updated signal processor, and a low (234 dB, two way) integrated cross-polar ratio (ICPR...

This study seeks to understand the degree of body cooling, cold perception and physical discomfort during Antarctic tour excursions. Eight experienced expedition leaders across three Antarctic cruise voyages were monitored during occupational tasks: kayaking, snorkelling and zodiac outings. Subjective cold perception and discomfort were recorded using a thermal comfort assessment and skin tempe...

the effects of different cooking methods (deep fat frying, boiling and steaming) on lipid content and fatty acid composition of grass carp ( ctenopharyngodon idella ) fillets during chill storage were investigated. fillet samples were cooked and then stored at + 4°c for 4 days. the control and the cooked fillet samples were analyzed for their chemical characteristics. twelve fatty acids were id...
