The euphoria of technology In an earlier commentary (Kong, 1999), I raised the issue of distance from the c̀entre' as a barrier to a researcher's participation in the academic circuit, despite the advent of technology and the possibilities it brings of decreasing relative distance. In this commentary, I wish to focus on what technology may and may not do for teaching and learning, and thus to ba...

In this paper, we consider a decision-maker facing a financial risk flanked by a background risk, possibly non-financial, such as health or environmental risk. A decision has to be made about the amount of an investment (in the financial dimension) resulting in a future benefit either in the same dimension (savings) or in the other dimension (environmental quality or health improvement). In the...

Background: The aim of this study was to measure137Cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. This study will help to probe, if there is any health threat posed by 137Cs exposure to the residents of the area. Materials and Methods: Twenty five samples of soil and 6 samples of bricks were collected from diffe...

in this study bactericidal activity of a malodor neutralizer containing silver nanoparticles manufactured in iran has been tested. for this purpose different concentrations of the product encounter with staphylococcus aureus, pseudomonas aeruginosa and bacillus cereus then the activity were evaluated in different contact times. the products containing at least 200 ppm of silver nanoparticles we...

this work described one pot syntheses of polysubstituted 2,6- dicyanoaniline and 2-(3-oxo-1,3-diarylpropyl) malononitrile derivatives in the presence of mgo nanoparticles (nps) under grinding conditions and microwave irradiation, respectively. the simple experimental procedure includes shorter reaction times, higher yields, lower cost and environmental friendliness. other remarkable features ar...
