Background & Aims of the Study Irradiation with ultraviolet light (UV) is used for the disinfection of bacterial contaminants in the production of potable water. The main objective of the study was to investigate and model Disinfection By-Products (DBPs) formation due to the UV Irradiation of the Tajan River water under different Irradiation conditions. Materials & Methods: &nbs...

Dental polymers are primarily used in restorative dentistry and must serve both cosmetic and functional purposes. They must be adaptable for easy forming and final cure by simple techniques and equipment available in a dental laboratory or dentist’s office. The final prosthetic device must fit exactly in spite of shrinkage due to polymerization and high coefficients of expansion. The plastic mu...

Technical development and commercial implementation of the supercritical fluid spray process have produced the surprising result that coating appearance and performance can actually be improved by removing 60 to 80 percent of the organic solvent from solvent-borne coating formulations. Unlike normal diluent solvents and water, the decompressive release of supercritical carbon dioxide during spr...
