Introduction: The purpose of this research was to explain the protective effect of quercetin on cardiac fatigue caused by exercise in skyrunning runners. Methods: 26 professional sky running athletes voluntarily and purposefully participated in this race. Random people were placed in 2 groups: quercetin (13 people) and placebo (13 people). The race was held in the central Alborz mountains, the...
Understanding the factors limiting migratory behaviour is fundamental to conservation of diadromous fish. Applications of indices of habitat suitability are problematic for diadromous fish because fish presence and abundance in relation to habitat quality are confounded by barriers to fish migration. An alternative approach is to assess diadromous fish distributions in proportion to distance in...
Global climate change has resulted in a gradual sea level rise. Sea level rise can cause saline water to migrate upstream in estuaries and rivers, thereby threatening freshwater habitat and drinking-water supplies. In the present study, a three-dimensional hydrodynamic model was established to simulate salinity distributions and transport time scales in the Wu River estuary of central Taiwan. T...
â â â â â â â â â â â abstract â the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian â santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...
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...
An individual's adaptation to altitude and the likely improvement in sea level performance resulting from it are not easily predicted from a knowledge of his sea-level performances. In Mellerowicz's study (Table I) the outstanding sea-level runner (Oh) had the largest decrement on first going to altitude but showed the greatest improvement during the four weeks at St Moritz. The slowest sea-lev...
Sea level monitoring in the Arctic region has always been an extreme challenge for remote sensing, and in particular for satellite altimetry. Despite more than two decades of observations, altimetry is still limited in the inner Arctic Ocean. We have developed an updated version of the Danish Technical University’s (DTU) Arctic Ocean altimetric sea level timeseries starting in 1993 and now exte...
Recent aircraft and satellite laser altimeter surveys of the Amundsen Sea sector of West Antarctica show that local glaciers are discharging about 250 cubic kilometers of ice per year to the ocean, almost 60% more than is accumulated within their catchment basins. This discharge is sufficient to raise sea level by more than 0.2 millimeters per year. Glacier thinning rates near the coast during ...
The scale of human pressures on marine ecosystems gradually increased from local to global effects during the last centuries. Global warming, sea level rise and trans-oceanic spread of alien species are now or will be major drivers of ecological change in the Wadden Sea. Eutrophication may rank as a superregional effect as the organic matter turnover in the Wadden Sea is driven by import from t...
