in this research for study the effects of nitrogen fertilizer on yield and yield components of current rice cultivars was an experiment as factorial in rcbd with three replications where conducted during 2009 year in two locations (rice research institute, rasht, and rudsar, east of guilan). factors were cultivars (khazar, ali kazemi and hashemi), and nitrogen fertilizer levels (0, 30, 60, and ...

in order to investigation of nitrogen fertilizer split application effect on quantity yield and grain quality of rice varieties, an experiment was carried out based on rcbd design as split plot experiment in three replications in langroud in 2006. mainand sub factor were variety (hashemi and bahar 1) and five nitrogen fertilizer split application (split of 150 kg.ha-1 n at transplanting, stemmi...

This paper aims at shedding light on the Abbasid historian Isaac ibn Sulaiman Al-Hashemi (Alive 210 A.H/ 825 A.D) and his book History Biography. Based what other historians who copied him, investigates personal traits of Al-Hashemi, significance book, methodology, fields which he was interested in incorporating book. The concludes that adopted chronological annals methodology with special atte...

this study is a survey research. the population of the study was all specialists who have enough data about ways of sustainability rice cultivars that they were identified and studied through non-probability sampling (purposeful and snowball). to determine the validity of the questionnaire, face and content validity was used, and, to assess the reliability, inconsistency coefficient was used. i...

Secondary metabolite contents (total phenolic, flavonoid, tocopherol, and tocotrienol) and antioxidant activities of Hashemi rice bran extracts obtained by ultrasound-assisted and traditional solvent (ethanol and 50:50 (v/v) ethanol-water) extraction techniques were compared. Phenolic and, flavonoid compounds were identified using ultra-high performance liquid chromatography and method validati...

High-energy X-rays offer several advantages over lower energy photons including: lower skin dose, higher depth dose, smaller scattered dose to tissues outside the target volume and less rounded isodose curves. These advantages in physical dose distributions have led to significant improvements in clinical radiotherapy, and high energy linear accelerators are now a standard fixture of radiothera...
