Drip irrigation under plastic mulch is widely used and leads to periodic drying–rewetting (DW) cycles in Xinjiang, Northwest China. However, the effect of different wet dry alternation types on soil inorganic nitrogen transformation not clear. Studying these issues only provides reference for formulation fertilization systems but also great significance reducing non-point source pollution. An i...

The tethered particle motion (TPM) allows the direct detection of activity of a variety of biomolecules at the single molecule level. First pioneered for RNA polymerase, it has recently been applied also to other enzymes. In this work we employ TPM for a systematic investigation of the kinetics of DNA looping by wild-type Lac repressor (wt-LacI) and by hinge mutants Q60G and Q60 + 1. We impleme...

Oil and gas dependence the volatility of their prices is currently a serious challenge for Russian economy. Coincidently, export revenues from oil products are main source federal budget. Export diversification can contribute to risk reduction economy by increasing share other industries in structure. In this regard, present study examines determinants industrial regions using econometric model...

a flow-duration curve (fdc) illustrates the relationship between the frequency and magnitude of streamflow. applications of fdc are of interest for many hydrological problems related to hydropower generation, river and reservoir sedimentation, water quality assessment, water-use assessment, water allocation and habitat suitability. this study was carried out in 11 selected watersheds with commo...

Statistical literacy is a new goal for statistical educators. A core element of statistical literacy for consumers is the ability to read and interpret data in the tables and graphs published by national statistical offices. A core element for producers is the ability to create tables, graphs and reports that are unambiguous and comprehensible. It appears that comprehensibility is not considere...
