Cold gas micropropulsion is a sound choice for space missions that require extreme stabilisation, pointing precision or contaminationfree operation. The use of forces in the micronewton range for spacecraft operations has been identified as a mission-critical item in several demanding space systems currently under development. Cold gas micropropulsion systems share merits with traditional cold ...

The association between ambient temperature and acute exacerbation of chronic bronchitis (AECB) was still unknown. Therefore, we performed an epidemiological study in a large hospital of Shanghai to explore the relationship about temperature and outpatient visit for AECB. We adopted a quasi-Poisson generalized additive models and distributed lag nonlinear models to estimate the accumulative eff...

In this study, past (1970-2005) as well as future long term (2011-2099) trends in various extreme events of temperature and precipitation have been investigated over selected hydro-meteorological stations in the Sutlej river basin. The ensembles of two Coupled Model Intercomparison Project (CMIP3) models: third generation Canadian Coupled Global Climate Model and Hadley Centre Coupled Model hav...

that very often the more serious results of frostbite are directly due, not to excessive cold but to carelessly applied heat. The pathology of the disease, however, explains this apparent paradox. The prime cause of the condition, however, generally was damp clothing combined with extreme cold. Simple dry cold being seldom a cause of frost-bite by itself. The pathology of the disease is as foll...

AIM The purpose of this study was to assess differences in persons of a Hot or Cold nature (according to traditional Iranian medicine), in terms of changes in their neuroendocrine and immune systems. MATERIALS AND METHODS Thirty-seven (37) male volunteers (20-40 years old) were divided into two groups, by whether they had a Hot or Cold nature. In addition, the Warmth/Coldness ratio of all the...

The relationship between storms and extreme ocean waves in the North Sea is assessed using a long-period wave data set and storms identified in the Interim ECMWF Re-Analysis (ERA-Interim). An ensemble sensitivity analysis is used to provide information on the spatial and temporal forcing from mean sea-level pressure and surface wind associated with extreme ocean wave height responses. Extreme o...
