There is an enormous amount of math resources on the web: http://www.mathcentre.ac.uk (a British site), http://www.mathe-online.at (Austrian), http://www.matheprisma. de (German), and the virtual community site http://planetmath.org, to mention a few. Of course, our research group also created content, for instance, material for learning fractions, algebra, combinatorics, and statistics. Within...

To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...

Research into the use of eco-friendly materials, such as natural fibers, in brake pads has gained momentum last few decades. This can be attributed to potential fibers replace traditional materials tribological applications braking pads. The harmful impact commonly-used pad metal and mineral on human health environment necessitates development alternatives. Natural banana peels, palm kernels, s...

a novel mathematical model has been developed to aid the formulation of emulsion explosives. this mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a ms excel program. the effects of the different content of nh4no3, nano3, h2o, and span-80 and composite fuel oil...
