In order to construct a suitable scaffold for corneal cell culture and transplantation in vitro, different chitosan-chondroitin sulfate blended membranes were prepared and the properties of blended membranes were studied. Corneal stroma cells and corneal endothelial cells were seeded onto the blended membrane surface and the effects of the blended membranes on corneal cell attachment and metabo...

In physiological education, blended course formats (integration of face-to-face and online instruction) can facilitate increased student learning, performance, and satisfaction in classroom settings. There is limited evidence on the effectiveness of using blending course formats in laboratory settings. We evaluated the impact of blended learning on student performance and perceptions in an unde...

In the UK, use of ethanol in fuel as a fuel oxygenate/fuel supplement is currently limited but could rise in an effort to meet the requirements of the European "Biofuels" Directive. This Energy Institute study focussed on the risk that accidental releases of ethanol blended gasoline (EBG) (i.e. gasoline containing 10% or less of ethanol) could pose to UK groundwater resources. Ethanol is miscib...

The current work is aimed at the experimental investigation of the aldehyde and BTX (benzene, toluene and Xylene) pollutants emitted from a light duty spark ignition (SI) vehicle fueled on gasoline and ethanol-gasoline blended fuel, operating with a three-way catalytic converter (TWC). At the same time, the specific reactivity (SR) of these pollutants has also been addressed in this paper. The ...

There are concerns that biodiesel feedstock may compete with food supply in the long term, if the raw materials are vegetable virgin oils only. Therefore, throughout the world, large amounts of non-edible oil plants are available in nature. In this paper, experimental study has been carried out to analyze engine performance and emission characteristics for direct injection diesel engine using b...

the present study was performed to analyze some of the preventive vs. promoter factors of applying blended learning system in agricultural higher education as viewed from the perspective of khuzestan province's faculties of agriculture and natural resources' faculty members. statistical population of the study consisted of the members of agriculture and natural resources state college...
