in this study economic and welfare impacts of establishing irrigation water market in qazvin province as well as potentiality of irrigation water transfer under stress irrigation conditions in the cities of qazvin province were analyzed. to achieve the above objectives, positive mathematical programming model and state wide agricultural production functions were used. to achieve applicable resu...
The effect of spontaneously generated coherence on dynamical evolution of a multi-level atomic system consisting of three upper levels and a lower level is studied. For degenerate upper levels the population trapping in these levels increases in the steady state. 2004 Elsevier B.V. All rights reserved. PACS: 42.50.Lc; 32.50.+d; 32.80.-t
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
the purpose of this paper is to estimate the welfare cost of inflation in iran. we first use the long-horizon regression approach developed by fisher and seater (1993) to obtain an estimate of the inflation rate elasticity of money demand and then the baily’s consumer surplus approach to calculate the welfare cost function. the results show that reducing inflation rate from 40% to 0% increases ...
The boiler drum process is a nonlinear, complex and multivariable process which includes significant time delay. Therefore, the control on the water level in the drum is not easy and ideal. The first objective of this paper is to model the drum water level referring to 210 MW power unit for Nassiriyah thermal power plant. The second objective is to study the water level controller operation wit...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. current research involved designing and manufacturing of a new creep testing machine. the equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.to evaluate the equipment’s pe...
this paper deals with evaluating the thermal behavior of exterior walls in dwellings of a particular place. today, there is a huge increase in constructing multi-storey apartment buildings and single-family houses in the city of yazd, a city with hot dry climate and a rich historical architecture in iran. unfortunately, the new methods that are used nowadays to make the envelopes of these dwell...
