Research must precede clean-up, DoE warns

NACO must clean up phony NGOs in India.

Benefits of genetic research must be shared, international genome organization warns.

How 'clean' must a cavity be before restoration?

The metabolic activity in dental plaque, the biofilm at the tooth surface, is the driving force behind any loss of mineral from the tooth or cavity surface. The symptoms of the process (the lesion) reflect this activity and can be modified by altering the biofilm, most conveniently by disturbing it by brushing with a fluoride-containing toothpaste. The role of operative dentistry in caries mana...

Phytoremediation for Environmental Clean Up

Pollution is an undesirable change in the physical, chemical or biological characteristics of air, land and water that will waste or deteriorate our raw material resources. Modern technological innovations have increased pollution levels above the self cleaning capacities of the environment. In recent times, one of the major issues is the threat to human life from the progressive deterioration ...

Non-Local Topological Clean-Up

A new approach to topological clean-up of 2D meshes is presented. Instead of searching for patterns in a mesh and replacing them as in other methods, the proposed method replaces a region in a mesh only according to the boundary of that region. This simplifies the classification of the different cases, and allows mesh modification over greater regions in the mesh. An algorithm for quadrilateral...
