Although Hallstand research on the preparation of metal oxides and other materials for various applications increases exponentially, it is more important to understand the need for eco-friendly methods of preparation to preserve the environment.Most of the methods available today are expensive, environmentally harmful, and inefficient with respect
The paper describes discrete modelling of the retention behaviour of unsaturated porous materials.A network approach is used within a statistical volume element (SVE), suitable for subsequent use in hydro-mechanical analysis and incorporation within multi-scale numerical modelling.The soil pore structure is modelled by a network of cylindrical pipe
Olduvai Gorge is a site in Tanzania that contains the earliest indication of the existence of human ancestors.Paleoanthropologists have found literally hundreds of fossilized bones and stone tools in the area dating back millions of years, leading them to conclude that humans evolved in Africa.Equally important, at Laetoli, west of Ngorongoro Crate
A drug-eluting stent with rhombic-shaped drug reservoirs is proposed, aimed at providing long-term drug delivery and enhanced fatigue life.Unique rhombic-shaped reservoirs or channels on the stent struts can increase the total drug capacity and improve the stress distribution for longer Extender Spray fatigue life, without compromising other import
