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...
Applying 2D algorithms for inverting the potential field data is more useful and efficient than their 3D counterparts, whenever the geologic situation permits. This is because the computation time is less and modeling the subsurface is easier. In this paper we present a 2D inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...
Several 2-ketomethylquinolines were synthesized by heating, 2-methyl quinoline with acyl chloride in the presence of AlCl3 Contrary to reported procedures, this method was accomplished at a short time obtaining good results.
A novel chemosensor based on unsymmetrical squaraine dye (USQ-1) for the selective detection of Hg(2+) in aqueous media is described. USQ-1 in combination with metal ions shows dual chromogenic and "turn-on" fluorogenic response selectivity toward Hg(2+) as compared to Li(+), Na(+), K(+), Mg(2+), Ca(2+), Ba(2+), Al(3+), Cu(2+), Cd(2+), Mn(2+), Fe(3+), Ag(+), Pb(2+), Zn(2+), Ni(2+) and Co(2+) du...
