The effects of drought stress at different growth stages and nutrition systems were studied on yield and yield components of wheat (Chamran cv.). This experiment was carried out as split plot based on completely randomized blocks design with three replications at Research Farm of Ramin University of Agriculture and Natural Resources, Khuzestan province, Iran, during 2009-2010. Irrigation at thr...
in order to study the effect of drought stress and harvesting stages on quantitative and qualitative yields of coriander (coriandrum sativum l.) this experiment was conducted on split plot based on a randomized completely block design with 3 replications in torbat-e heydariyeh university, iran, during growing season of 2010-2011. treatments were drought stress (in three levels no stress: contro...

abstract the limitation of water sources in most places all over the world, especially in arid and semi-arid lands is an important issue for those who live in these areas. many governments have dedicated their efforts toward finding new water resources to obtain water. fog and cap clouds harvesting are one of the candidate methods to produce pure water. many countries including chile, peru, ecu...
Storage tanks from rainwater harvesting systems (RWHs) are designed to provide flow equalization between rainfall and water demand. The minimum storage capacity required take into account the maximum variations of stored volumes, i.e., active storage, depends basically on magnitude variability profiles size Given random nature variables involved in hydrological process, probability theory is a ...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
Aims and Background: The water resources conservation includes all measurements focusing on optimal consumption and reduction of stress on water resources and its final consequence is energy and financial resources saving. Aim of this study was to examine economically consequences of conservation practices and their impacts on groundwater resources management. Methodology: Examination of alloca...
