Introduction Alluvial fans are considered as one of the arid and semi-arid geomorphic effects, which are the result of intense flow water performance in the past and present. Therefore, alluvial fans can be considered as legacies of quaternary climate. Dryv (1873) used alluvial fan terminology for the first time. The US geographical organization conducted a study focusing on alluvial fans in...
Widespread basaltic volcanism occurred in the region of the West Siberian Basin in central Russia during Permo-Triassic times. New 40Ar/39Ar age determinations on plagioclase grains from deep boreholes in the basin reveal that the basalts were erupted 249.4 +/- 0.5 million years ago. This is synchronous with the bulk of the Siberian Traps, erupted further east on the Siberian Platform. The age ...
Abstract Background and objectives: Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway. G6PD deficiency (an X-linked recessive hereditary disease) is an inherited condition affecting approximately 3% of the people globally. This deficiency can cause hemolytic anemia and jaundice in neonates. The goal of this study is to detect the prevalence of G6PD deficienc...
Splash (raindrop) erosion plays an significant role in soil loss, especially in arid and semi-arid regions with poor vegetation. In this paper, by analyzing the pattern of rainfalls that occurred during 26 years in four basins located in Semnan County, their effect on the pattern of eroded sediments from the basin was investigated. Sedimentary layers from the sampling of retarding reservoir sed...
