abstract the present study is concerned with the syntactic deviation in hafezs poetry. poems are known to be accompanied with various linguistic deviations. these deviations may be phonological, morphological and/or syntactic. the relatively high frequency of the cases of the syntactic deviation in hafezs poems makes this rhetorical feature as a main characteristic of his poetry. this thesis, ...
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
to study the stability and adaptability of grain yield and genotype × environment interaction, 19 promising triticale lines/varieties were evaluated in moghan, mashhad and zabol experimental stations during 2001 to 2003 cropping seasons. the experimental design in all the locations and years was completely randomized block design with three replications. combined analysis of variance c...
the present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. the prepared nanocapsules were used for controlled drug release of anticancer agents with gold and iron oxide nanoparticles. ...
to determine the yield stability, adaptability and analysis of the genotype× environment interaction of virginia tobacco, 15 hybrids of tobacco including 10 iranian and 5 international hybrids were evaluated in two different experiments (water stress and normal irrigation) using a randomized complete block design (rcbd) with three replications at two locations including rasht and tirtash tobacc...
چکیده بهبود برآوردگرهای پارامترهای جامعه مورد توجه برخی از آماردانان تحت شرایط متفاوت می باشد. در سالهای اخیر لاهیتران و ویجکون)2009) برآورد پارامترهای جامعه را زمانیکه اطلاعات اضافی در دسترس باشد بهبود دادند و روش تعمیم یافته ای را برای بدست آوردن برآوردگرهای انقباضی بهینه معرفی کردند. ما می خواهیم براساس قضایایی که لاهیتران و ویجکون مطرح کردند برآوردگرهای انقباضی را برای پارامترهای میانگی...

the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
drought is one on the most important factors limiting the productivity of spring chickpea in drylands of iran. sixtym genotypes of chickpea from icarda's germplasm accessions, as well as one drought susceptible check (ilc 3279), were sown in spring of 2010 at two locations, sanandaj and maragheh, in the western highlands of iran for one year. the experiment in each location was laid out in a ra...
