postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
the present study was conducted to investigate the role of summary in teaching grammar process on pre-university students. to this end, 48 male pre-university students in semnan were participants. they were math class that we called experimental group and science class as control group. in order to make sure there was no significant difference in proficiency level of two groups. a pre-test wa...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Irrigation has a major role to play in the productivity of winter maize. Precise information about quantity and quality irrigation water is key for higher In present study attempt been made asses impact different depth on crop yield biomass maize using FAO-Aquacrop Model. first case was simulated varied from 20 mm 80 mm, keeping constant. Similarly, another optimum kept constant 1 10 ds/m. The ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
BACKGROUND Interest in the cultivation of biomass crops like the C4 grass Miscanthus x giganteus (Miscanthus) is increasing as global demand for biofuel grows. In the US, Miscanthus is promoted as a crop well-suited to the Corn Belt where it could be cultivated on marginal land interposed with maize and soybean. Interactions (direct and indirect) of Miscanthus, maize, and the major Corn Belt pe...
Neonicotinoid seed treatments, typically clothianidin or thiamethoxam, are routinely applied to >80% of maize (corn) seed grown in North America where they are marketed as a targeted pesticide delivery system. Despite this widespread use, the amount of compound translocated into plant tissue from the initial seed treatment to provide protection has not been reported. Our two year field study co...
در این کار تحقیقاتی به منظور افزایش حلالیت داروی سلکوکسیب که دارای حلالیت ناچیزی در آب می باشد از یک سیستم میکروامولسیون استفاده شده است. برای تحقق این هدف و طراحی چنین سیستم میکروامولسیونی، ابتدا دیاگرام فاز با نسبت 3به 1 از سورفکتانت به کوسورفکتانت رسم شد. سپس با استفاده از دیاگرام فاز، ناحیه ی میکروامولسیون که یک منطقه ی شفاف بوده و از پایداری ترمودینامیکی بالایی برخوردار است انتخاب می گردد....
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
