Climatic conditions have dried up since the late 5th millennium BC as if Paleoclimate research in the northern hemisphere, particularly Iran and neighboring countries, shows unfavorable climatic conditions and several periods of severe drought during 4th millennium BC. Also, based on environmental sedimentological studies on archaeological sites such as Mafin Abad of Islamshahr and Meymanat Aba...
چکیده فشارش زاویه ای در کانال های همسان(ecap) یکی از پرکاربردترین روش های تغییر پلاستیک شدید می باشد که با ریز کردن دانه ها و ایجاد تکسچر مناسب باعث بهبود استحکام و انعطاف پذیری می شود. در این تحقیق از یک قالب با زاویه داخلی 120 درجه استفاده شد و آلیاژ aa5051 بعنوان ماده مورد آزمایش انتخاب گردید. ecap در 4 پاس و در مسیرهای a، c، ba و bc در دمای c°200 انجام شد. ریزساختار و خواص مکانیکی مورد مطا...

Background: Radiotherapy is regarded as a standard treatment modality in breast cancer (BC). Radiation causes cellular damage both in cancer and normal cells by inducing DNA-damage and chromosomal aberrations (CA). Different agents were used for ameliorating effects of radiation, mainly antioxidants such as melatonin. Melatonin shows oncostatic properties on human BC. The aim of this study was ...
BACKGROUND Near-infrared spectroscopy is proposed as a method for providing real-time urea concentrations during hemodialysis treatments. The feasibility of such noninvasive urea measurements is evaluated in undiluted dialysate fluid. METHODS Near-infrared spectra were collected from calibration solutions of urea prepared in dialysate fluid. Spectra were collected over three distinct spectral...
In this study flowering time and other important morphologic traits were evaluated during two years in F1 almond progenies of seventy two seedlings from cross between the intermediate flowering Italian cultivar ‘Tuono’ and the extra-late blooming Iranian cultivar ‘Shahrood-12’. A modified-bulk segregant analysis in combination with the application of the 140 RAPD primers, 87 nuclear ...
