Adaptation takes place not only when going to high altitude, as generally accepted, but also when going down to sea level. Immediately upon ascent to high altitude, the carotid body senses the lowering of the arterial oxygen partial pressure due to a diminished barometric pressure. High altitude adaptation is defined as having three stages: 1) acute, first 72 hours, where acute mountain sicknes...

the aim of this research is the assessment of the relation between rainfall and large scale synoptically patterns at khorasan razavi province. in this study, using adaptive neuro fuzzy inference system, the rainfall estimation has been done from april to june in the area under study. spring rainfall data including the information of 38 synoptic, climatologic and rain gauge stations from 1970 to...

UNLABELLED Blood pressure increases during acute exposure to high altitude in healthy humans. However, little is known on altitude effects in hypertensive subjects or on the treatment efficacy in this condition. Objectives of High Altitude Cardiovascular Research (HIGHCARE)-Andes Lowlanders Study were to investigate the effects of acute high-altitude exposure on 24-hour ambulatory blood pressur...

Quantifying faults in manufacturing processes is a crucial concern, particularly in new manufacturing processes where continual product improvement is desired. We present an approach to incrementally diagnose fault patterns on surfaces of product components. Contemporary experimental and surface-analysis techniques are adapted at each step of the approach. Specifically, a maturing layeredmanufa...

abstract: numerical weather forecasting models are used for forecasting and dynamic conditions analysis of atmosphere phenomena in recent years. this research investigates dynamic and thermodynamic conditions in heavier precipitation events in different synoptic patterns in the southern coasts of caspian sea using wrf model. database precipitation events were formed. super heavy and heavy preci...

Seasonal changes of the Adriatic Sea level, obtained by analyses of monthly sea level data measured at the Split tide gauge station in 1958-2001, are reported. The data were correlated by multivariant analysis to (1) local meteorological data on air temperature, air pressure, and precipitation, collected at the Split station and data on winds obtained from ECMWF ERA40 Reanalysis fields and (2) ...

BACKGROUND Aeromedical transport of critically ill patients requires continued, accurate performance of equipment at altitude. Changes in barometric pressure can affect the performance of mechanical ventilators calibrated for operation at sea level. Deploying ventilators that can maintain a consistent tidal volume (VT) delivery at various altitudes is imperative for lung protection when transpo...
