Unfortunately, in situations of protracted and high sweat secretion, the body water content will become progressively reduced, and the blood volume slowly declines. This is well tolerated within healthy individuals. However, the regulation of blood pressure has a higher homeostatic priority than does temperature regulation, since low pressures cannot support adequate tissue perfusion, and will ...

Previous research on Dengue Fever have involved laboratory tests or study areas with less diverse temperature and elevation ranges than is found in Colombia; therefore, preliminary research was needed to identify location specific attributes of Dengue Fever transmission. Environmental variables derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Tropical Rainfall Measurin...

PRISM (Parameter-elevation Regressions on Independent Slopes Model) is a climate analysis system that uses point data, a digital elevation model (DEM), and other spatial datasets to generate gridded estimates of annual, monthly and event-based climatic parameters (Daly et al. 1994). Originally developed in 1991 for precipitation estimation, PRISM has been generalized and applied successfully to...

Infrared observations of seaborne thermal sources are subject to the effects of atmospheric refraction. For low elevation angles at long ranges, out to the limit of visibility, the inevitable atmospheric temperature gradients frequently produce mirages. I present an analysis of a 22-min sequence of images recorded on 18 February 1994 at the U.S. Naval Surface Warfare Center at Wallops Island, V...

BACKGROUND Brugada Syndrome (BS) is an inherited ion channelopathy characterized by an electrocardiographic (ECG) pattern of a coved type ST segment elevation in right precordial leads with or without right bundle branch block. CASE PRESENTATION A 23-year old male presented with right lower quadrant abdominal pain. Further evaluation revealed a diagnosis of acute appendicitis. The patient dev...

We have observed an elevation of body temperature during surgical repair of pectus excavatum. To document this phenomenon and attempt to prevent it, we undertook a combination retrospective-prospective study. The retrospective arm included an analysis of the anesthetic records of patients undergoing repair of pectus excavatum during the past 5 years and included 22 boys and 3 girls. Body temper...

Two extreme configurations under short circuit conditions leading to the punch through Trench IGBT failure under the effect of the temperature and the gate resistance have been studied. By analyzing internal physical parameters, it was highlighted that the elevation of the temperature causes an acceleration of the failure which is due to a thermal runaway phenomenon, whereas the influence of th...

Abstract Aims Species diversity–productivity relationships in natural ecosystems have been well documented the literature. However, biotic and abiotic factors that determine their are still poorly understood, especially under future climate change scenarios. Methods Randomized block factorial experiments were performed three meadows along an elevational gradient on Yulong Mountain, China, where...
