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...
a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...

abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
The expression ' typing of blood' has been applied loosely to determination of blood groups. It should not be so applied. One groups blood in determining 0, A, B and AB; types blood in determining M, N and MN; Rhesus groups blood in determining the Rh -fand Rh states; and Rhesus types (or Rh types) blood in determining R-h0, Rh', Rh", Rh'Rh", Rh15 Rh2, RhjRh2, and rh (using C-D-E system for a p...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
