TOXIC HAZARDS FROM SOLVENT EXPOSURE IN METAL PLATING INDUSTRIES Daniel

The first of these chemicals, mineral spirits, is known by a number of different names. Benzine, petroleum spirits, mineral turpentine, naphtha and painters naphtha are just a few of the synonyms of mineral spirits. This solvent is actually a mixture of a number of different hydrocarbons. It is distilled from petroleum and is composed of chemicals having generally five to seven carbons. It repr...

An Information System for a Bauxite Mine

Bauxite is mined and transported by conveyor to a processing plant, screened and washed, then placed into blended stockpiles to feed the alumina refinery. While being stacked to the stockpile, the ore is sampled. Completed stockpiles must be acceptably close to target grade (composition), not only in alumina, but also in residual silica, carbon and sodium carbonate. The mine is an open-cut pit....

Assessing Saudi Arabian Business It Capabilities for Online Selling Adoption

This study investigates the impact of online selling opportunities in Saudi Arabia using Net-Enabled Business Innovation Cycle (NEBIC). The research model has three factors:1) selecting enabling technologies (SET); 2) comparing proposed technologies with economic opportunities (CEO); and 3) implementing information technology as business innovation for growth (IITBIG). The model explores power ...
