Highland populations living permanently under hypobaric hypoxia have been subject of extensive research because of the relevance of their physiological adaptations for the understanding of human health and disease. In this context, what is considered high altitude is a matter of interpretation and while the adaptive processes at high altitude (above 3000 m) are well documented, the effects of m...

The average person's view that sea level is constant is not shared by everyone, and for good reason. Petroleum companies and their geologists find oil on dry land once covered by prehistoric seas, and paleontologists find marine fossils on desert plains. Nevertheless, within the period of time relevant to most decisions, the assumption that sea level is stable has been appropriate. Only in a fe...

hypoxia and hypocapnia can cause broncho-constriction in human subjects, and this could have a bearing on performance at high altitude. the object of this study was to examine how pulmonary ventilatory functions during high-altitude trekking. this study is a cohort study on spirometric parameters at different altitudes. fifty six healthy male volunteers from a university student population were...

Purpose: The purpose of this study was Comparison of pulmonary function parameters changes at different altitudes in female athletes. Methods eleven voluntary Female athletes, (age; 22.27±0.65yr), (weight; 57.00±6.31kg), (Fat%:20.81±3.2 1) (Height; 160.54± 3.7cm and vo2max: 40.65±1.00) were selected to this study on spirometric parameters. Each subject was informed consent form. Respiratory fun...

In this paper I presented the results obtained for the differential energy spectra of muons at sea level determined as a function of three zenith angles. I calculated the shower size and the number of muons per square meter as a function of the lateral distance from the center of the shower. The data interpretation provide the most significant physical information for understanding the main pro...

Abstract 
 Material Sugarcane natural fiber material can be used as a sound absorber material. In measuring the value of absorption coefficient cane silencer using level meter application on smartphone to measure intensity (dB) and frequency generator connected speaker source (Hz). The test uses an acoustic box miniature room that will tested for its values coated with sugarcane fibers. pu...

Understanding the broad-scale ramifications of accelerated sea level rise requires maps of the land that could be inundated or eroded. Producing such maps requires a combination of elevation information and models of shoreline erosion, wetland accretion, and other coastal processes. Assessments of coastal areas in the United States that combine all of these factors have focused on relatively sm...

A major West Antarctic ice stream discharges by sudden and brief periods of very rapid motion paced by oceanic tidal oscillations of about 1 meter. Acceleration to speeds greater than 1 meter per hour and deceleration back to a stationary state occur in minutes or less. Slip propagates at approximately 88 meters per second, suggestive of a shear wave traveling within the subglacial till. A mode...
