development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

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...

Estimation of cost efficiency for firms in different technologies using data envelopment analysis

Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...

Bank Size, Returns to Scale and Cost Efficiency

Since the passage of Dodd-Frank, government regulators have become more interested than ever in the significant increase of bank size in the U.S. financial sector. To shed light on the reasons of the bank size increase and its effects on banks, we study the dynamic interactions between size, cost efficiency and returns to scale. Using Fourier flexible form, we show that banks of all but the lar...
