drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

In the present study, in a quenching–partitioning (Q–P) process, effects of partitioning time (Pt) and temperature (PT) on mechanical microstructural properties microalloyed Fe-0.21C-1.5Si-2.2Mn-0.054Al-0.08Ti steel were studied. The XRD SEM results confirmed increases retained austenite ( $${\gamma }_{\mathrm{R}}$$ ) volume fraction $${V}_{{\gamma }_{\mathrm{R}}})$$ carbon concentration by inc...

[1] Accurate representation of surface energy partitioning is crucial for studying land surface processes and the climatic influence of land cover and land use change using coupled climate-land surface models. A critical question for these models, especially for newly coupled ones, is whether they can adequately distinguish differences in surface energy partitioning among different vegetation t...

Methods are presented for selecting values of chemical properties of vapor pressure, water solubility, Henry's law constant, and octanol-water and octanol-air partition coefficients, which are subject to thermodynamic constraints, while taking advantage of all measurements. The aim of the mathematical procedures is to find the one set of internally consistent partitioning parameters that is min...
