A new chemical vapour deposition (CVD) technique is presented. It is especially advantageous for the deposition of compound materials. The technique improves the uniformity and reproducibility of the deposition. The economical use of gaseous reactants is improved by a factor varying between 5 and 20. This is important in the case of expensive metal-organic CVD methods. The method consists in th...

Yield prediction before harvesting is one of the tools in order to planning food production supply in future.Yield prediction was carried out for Wheat(Triticum aestivum) using different meteorological variables with agrometeorological indices in Hamedan district during 2003-04 and 2004-05. According to correlation coefficients, standard error of estimate as well as relative deviation of predic...

      A quanitative structure property relationship was proposed to calculate the binary interaction terms of the Jouyban-Acree model using solubility parameter, boiling point, vapour pressure and density of solvents. The applicability of the proposed method for reproducing solubility data of anthracene in binary solvents has been evaluated using 116 solubility data sets collected from the lite...

Abstract In the present paper, an enhanced Volume of Fluid model is applied for conduction parametric numerical simulations, to investigate break-up phenomena accelerating, elongated, vapour bubbles, within circular mini-channels. The effect fundamental controlling parameters in resulting characteristics investigated. Four different series simulations isolated bubbles mini-channels are performe...

expansion of apple growing to dry areas requires reliable approaches to select genotypes tolerant to water stress. we have simulated apple tree transpiration (ec) from different commercial orchards and compared it with actual transpiration (ea) derived from sap flow measurements. the modelling approach lies in rearranging a parameterized p–m equation and incorporating in it a stomatal conductan...

Near-ambient-pressure X-ray photoelectron spectroscopy enables the study of the reaction of in situ-prepared methylammonium lead iodide (MAPI) perovskite at realistic water vapour pressures for the first time. We show that MAPI decomposes directly to PbI2, HI and NH3 without formation of methylammonium iodide, allowing us to distinguish between alternative mechanisms for the atmospheric degrada...
