the effect of gibberellic acid (ga3) and benzyladenine (ba) on aloe vera was evaluated at pot cultivation conditions. this study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 and ba at 0, 100, 200 and 400 mg.l-1 levels. the nu...
شبیهسازی رشد، عملکرد، نیتروژن دانه و کارایی مصرف آب ارقام ذرت دانهای با استفاده از مدل CERES-Maize
In this research, CERES-Maize crop model was calibrated, validated and evaluated for different maize hybrids under climatic conditions of Gonabad, east of Iran. For this purpose, an experiment was carried out based on a split-split plot randomized complete blocks design. Main factor consisted of three irrigation regimes (optimum irrigation, moderate drought stress, and severe drought stress), s...
Understanding weather zoning and knowing homogeneous climate regions are essential for land use and regional planning. The aim of this study was to compare three different geographical climate of Iran, the Caspian coastal, mountainous and arid interior of the provinces of Mazandaran, Semnan, Tehran, Qazvin, Qom, and Markazi. In order to do this study, climatic data of 56 synoptic and climatolog...
chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...
Understanding the evolution of asteroid spin states is challenging work, in part because asteroids have a variety of orbits, shapes, spin states, and collisional histories but also because they are strongly influenced by gravitational and non-gravitational (YORP) torques. Using efficient numerical models designed to investigate asteroid orbit and spin dynamics, we study here how several individ...
a study was conducted to determine the effects of diet formulation on arian broiler breeder performance in their 50 to 64 wks of age. one hundred and sixty eight female and 24 male breeders were employed in 8 treatments of 3 replicates (7 females plus a male) in a completely randomized design (a factorial experience of 2 × 2 × 2). eight experimental diets were formulated based on three factors,...
the synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(ii) complexes are described. all five compounds have the general formula [cu2(l)4(o-r)2](cl)2 or [cu2(l)2(cl)2](cl)2, in which r = ch3 or h, l=2, 3 or 4-pyridinemethanol as l2, l3 or l4, respectively. the title compounds consist of dinuclear units with bridging methoxo groups in [cu2(l4)4(o-ch3)2](cl)2, hydro...
Congenital fistulae between the tracheobronchial tree and oesophagus usually originate from the lower end of the trachea or right main bronchus. The case history is presented of a man in whom a fistula between the oesophagus and left main bronchus was not diagnosed until the age of 48.
The looming maladaptive style is a cognitive variable that increases the individual’s vulnerability to anxiety. Looming cognitive style is assessed by the Looming Maladaptive Style Questionnaire (LMSQ-R). This study investigated the structure, validity, consistency, and stability of a Farsi translation of the LMSQ-R in a sample of Iranian students. Three hundred and forty three students (...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
