تحقیقات اخیر روی روشهای عددی، بر ایده استفاده از روشهای بدون شبکه{meshfree methods} برای حل عددی معادلات دیفرانسیل با مشتقات جزئی تاکید می کند. یکی از ویژگی های رایج همه روشهای بدون شبکه، توانایی آنها در ساخت تقریب تابع، تنها با استفاده از اطلاعاتی در یک مجموعه از داده های پراکنده می باشد. تعدادی از روشهای بدون شبکه عبارتند از: روش هیدرودینامیکهای ذره ی هموار{smooth particle hydrodynamics ...
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...
Heretofore, unscheduled DMA synthesis (UDS) induced by DMA-damaging chemicals has been measured in nonreplicating human fibroblasts by autoradiographic meth ods that are not readily applicable to organotypic epithe lial cell cultures. In order to evaluate the range of chemi cal sensitivity and DNA repair response of human skin epithelial cells, we have developed a novel semiquantitative in vitr...
هدف از ارایه این پایان نامه بررسی روشی است برای حل معادلات دیفرانسیل غیرخطی که شکل عمومی آنها بصورت lu+nu=g(t) می باشد. در این معادله n یک عملگر غیرخطی و l یک عملگر دیفرانسیلی خطی می باشد. این روش تحت عنوان روش تجزیه (آدومیان) بررسی می شود. در این روش u رابه صورت u تجزیه می کنیم. همچنین ترکیب غیر خطی nu را بصورت an (u , u , ... , u ) نمایش می دهیم که a ها چند جمل...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
structure of which is shown in Chart 1, appears to have the maximum potential for clinical use. In the course of studies on the mechanism of the radiation sensitization of hypoxic cells by electron-affinic nitmocom pounds, it was observed that: (a) NIMP is more toxic to hypoxic cellsthan oxygenated celhs(16, 17) and (b) preincu bation of cells with NIMP under hypoxic conditions at 37° enhances...

The interaction of IT-eleetrons in [2.2] phanes was studied both experimcntally and theoretically. The fluorescence and phosphorescence spectra were measured at liquid helium temperature; in addition, the zero field splitting parameters D and E were detcrmined by ODMR in zero field and by ordinary ESR at X·band. The results for the phanes with two identical aromatic units can be summarized as f...
