abstract a field experiment was conducted at plant pest and disease research institute in karaj,iran in 2005-2006 to determine the effect of low herbicide dose of clodinafop-propargyl on percentage of wild oat control, yield and economic return of wheat. the experiment included 2 wheat varieties (rooshan and niknejad (less and more competitiveness cultivar, respectively, 4 wild oat densities (0...

heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...

Abstract Five bread wheat (Triticum aestivum L.) cultivars including Kavir, Pishtaz, Niknejad, Omid and Roshan were evaluated in a split plot experiment based on randomized complete block design with three replications. Water stress and well-watered conditions were assigned to the main plots and varieties to the subplots. Water stress was imposed by withholding irrigation at the booting stage....

abstract common root rot induced by bipolaris sorokiniana, is one of the most important diseases of wheat. chemical control of this disease is difficult because of it is a soil-born pathogen, so that, application of other methods is useful to reduce disease level especially resistance cultivars. in this research, were examined reaction of some wheat cultivars and lines against common root rot i...

LO Generation and Distribution for 60GHz Phased Array Transceivers by Cristian Marcu Doctor of Philosophy in Electrical Engineering University of California, Berkeley Professor Ali M. Niknejad, Chair Increased memory capacity and processing power in mobile devices has created a need for radios that can transmit data at multi-Gb/s rates over a short range. However, battery capacity has not kept ...

This dissertation presents a low-quiescent-current dual-mode digitally-controlled buck converter IC for cellular phone applications. In cellular phones, the load current demanded by the on-board circuitry varies from below 0.1 mA up to a few hundred mA, reflecting operation in standby and active (talk) modes. Thus, high efficiency over a wide load range is of high priority for power management ...
