?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...
most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...
based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...
نوسان ساز ها جزء لا ینفک بسیاری از سیستم های الکترونیکی هستند. کاربرد های آنها تولید ساعت در ریزپردازنده ها تا سنتز فرکانس حامل در تلفن های سلولی را در بر می گیرد که نیاز به توپولوژیهای متفاوتی از نوسان ساز ها با درجات متفاوتی از کارایی دارند.طراحی نوسان ساز مقاوم و کارا در فناوری cmos جزء مسائل جالب است.معمولا نوسان ساز ها را در یک حلقه ی قفل فاز(pll) بکار می برند با توجه به کاربرد pll ، بحث م...
the microstructure of dual phase steels can be considered as a matrix of ferrite phase reinforced by martensite particles. recent measurements show that the mechanical properties of the ferrite phase are changed with the distance from the martensite grains. in this paper, a new method has been proposed to consider this phenomenon in finite element modeling of dual phase steels microstructure. i...
cml in breif cml is characterized by the proliferation of large numbers of immature wbc in the blood and bone marrow. in most of the patients , it is a clonal disorder in which all cell lines, express the philadelphia chromosome)q/22 translocation(it accounts for 20 of all leukemias and most cases occur over 25 yrs of age. the disease usually begins insidiously,but symptoms referable to anemia ...

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
چکیده: فاز هندسی یک فاکتور فاز انتگرال ناپذیر است که از ترابرد بی دررو یک سیستم حول یک مسیر بسته در فضای پارامترش بوجود می آید. اخیراً توجه زیادی به اثر فاز هندسی در سیستم های اسپینی معطوف شده است که در این رساله به بررسی می پردازیم. با استفاده از یک رهیافت جدید که برپایه مکانیک کوانتوم برهمکنش اسپین-مدار استوار است، به مطالعه ترابرد قطبش فوتون های در محیطهای ناهمگن می پردازیم[1]. این رهیافت ق...
