The Junggar Basin, where twenty-seven oil fields and five gas have been discovered, is a typical “oil basin” with proven ratio of natural 5.3%. amount from Permian source rocks has found in the western margin basin, but no large-scale reservoir discovered. key to exploration whether oil-prone large generation potential. Based on comprehensive analysis geochemical features hydrocarbon simulation...

Liquid water and ice are the dominant agents of erosion and sediment transport in most actively growing mountain belts. An exception is in the western Qaidam basin along the northeastern margin of the Tibetan Plateau, where wind and windblown sand have sculpted enormous yardang fields in actively folding sedimentary strata. Here, we present observations suggesting that since the late Pliocene, ...

background: educational evaluation is a process which deals with data collection and assessment of academic activities’ progress. in this research, educational evaluation of dentistry school of tehran university of medical sciences, which trains students in undergraduate and residency courses, was studied. methods: this descriptive study was done with a model of educational evaluation in ten st...

Evapotranspiration (ET) is an important component of the eco-hydrological process. Comprehensive analyses of ET change at different spatial and temporal scales can enhance the understanding of hydrological processes and improve water resource management. In this study, monthly ET data and meteorological data from 57 meteorological stations between 2000 and 2014 were used to study the spatiotemp...

The magnetometer and electron reflectometer experiment on the Lunar Prospector spacecraft has obtained maps of lunar crustal magnetic fields and observed the interaction between the solar wind and regions of strong crustal magnetic fields at high selenographic latitude (30 degreesS to 80 degreesS) and low ( approximately 100 kilometers) altitude. Electron reflection maps of the regions antipoda...

several strains of saccharomyces cerevisiae were isolated from different sources. these strains were under taken for ethanol tolerance analysis and growth under stress condition. exponential phase to various concentrations of ethanol (2–26% v/v) for 1 h was used for isolation of resistant strains. viable cells were isolated and purified by inoculation of diluted samples on yeast extract peptone...
