In this paper, different input-oriented ratio-based DEA (DEA-R-I) models are proposed. By presenting the envelopment-additive-enhanced Russell model based on the DEA-R-I form, each decision making unit is evaluated and its efficiency score is calculated. Also, by presenting the central resource allocation model based on the DEA-R-I form, a suitable benchmark for all DMUs is proposed by solvin...

introduction: general medical education starts with basic sciences which usually continue about 2.5 to 3 years. in this period, the students study basic medical sciences and then start the clinical stage in which they deal with diagnoses, care, and cure of disease. the purpose of this study was to assess the integration of basic sciences period with the clinical period at shiraz university of m...

Using low cost hardware and the Visual Basic programming language, we have developed teaching modules which can effectively introduce basic science and technology principles at several levels from high school to freshman Electrical Engineering. We have tested these methods in a NSF sponsored course designed to teach high school teachers how to introduce science and technology to their students....

This research presents adsorption potential of surfactant (sodium dodecyl sulphate; SDS) coated magnetite nanoparticles as suitable and efficient adsorbent for the removal of Basic Blue 41 (BB 41), as a cationic dye from textile’s company wastewater. The effects of various experimental parameters (e.g. initial pH of the solution, SDS amount, and ionic strength) on the adsorption efficiency of B...
