let $l$ be a lie algebra, $mathrm{der}(l)$ be the set of all derivations of $l$ and $mathrm{der}_c(l)$ denote the set of all derivations $alphainmathrm{der}(l)$ for which $alpha(x)in [x,l]:={[x,y]vert yin l}$ for all $xin l$. we obtain an upper bound for dimension of $mathrm{der}_c(l)$ of the finite dimensional nilpotent lie algebra $l$ over algebraically closed fields. also, we classi...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
abstract background patients who are to receive chemotherapy require careful assessment of liver function prior to treatment to determine which drugs may not be appropriate, and which drug doses should be modified. following therapy abnormalities of liver function tests may be due to the therapy rather than to progressive disease, and this distinction is of critical importance. toxicity such as...
the present study aimed at investigating the relationship between iranian efl teachers’ classroom management orientations and their teaching styles. additionally, the difference between male and female teachers’ teaching styles and classroom management orientations and their relationship with experience and age were explored. three hundred efl teachers filled in attitudes and beliefs on classro...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
در این پایان نامه میانگین پذیری مدولی ضعیف جبر باناخ a که با اعمال سازگار روی یک جبر باناخ دیگر a یک مدول باناخ است را تعریف کرده و نشان میدهیم که تحت چه شرایطی میانگین پذیری مدولی ضعیف a^(**) میانگین پذیری مدولی ضعیف a را نتیجه خواهد داد. همچنین به همراه نتایج دیگر، رابطه ی بین آرنز منظم پذیری مدولی یک جبر باناخ و میانگین پذیری مدولی دوگان دوم آن را بررسی می کنیم. به عنوان یک نتیجه ثابت می کنی...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

در ابتدا دی اسید (35) حاوی واحد بای سیکلو و قطعات ایمیدی با موفقیت تهیه شد و سپس توسط دی آمینهای مختلف در حضور tpp/nmp/py پلی(آمید- ایمید)های (a-f37) تهیه و خصوصیات آنها مورد بررسی قرار گرفت. در ادامه کار، قسمت اول تهیه و خصوصیات دو دسته از پلیمرهای سنتزی بررسی شده است. دسته اول که شامل پلی(آمید- ایمید)های مقاوم حرارتی و ضد آتش می باشند، از واکنشهای تراکمی مستقیم بین انواع دی اسید ها شامل -n,n...
