In this paper, a new structure is proposed for boost dc–dc converter based on the voltage-lift (VL) technique. The main advantages of are its lack transformer, simple structure, free and low input current ripple, high voltage gain capability by using an source, suitable stress semiconductors lower output capacitance. Herein, analysis operating elements relations in continuous conduction mode (C...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

expansion of oilseeds cultivation plays an important role in provision of the required edible oils for a country's population. iran is one of the origins safflower as a drought and salt tolerant crop, and therefore, it can be counted on as a suitable alternative crop for cultivation in marginal areas. the aims followed in the present research were on evaluation and selection of late season...

to study general and specific combining ability of some rice varieties for grain physical properties and milling quality, a diallel design with five parents (hashemi, vandana, kadous, shahpasand and ir36) was used. parents and their f1 progenies (25 genotypes) were grown in a randomized complete blocks design with three replications in the research field of rice research institute of iran (rrii...
