The plating industry is one of the main toxic chemicals consumers, which uses various chemicals, including solvents, acids, bases, cleansers, sophisticated organic ingredients, and metal salts of cadmium, nickel and chromium. Due to the growing production of industrial waste in spite of actions related to these wastes’ management, no comprehensive pattern was introduced at different levels. Thi...

This is an analysis of different approaches in the use of technology by Boeing and DoD to determine how they may have affected development time for the C-17 and the Boeing 777. Boeing’s focus on cost, schedule, performance, and market competition is contrasted to DoD’s focus on performance. The paper concludes that the mere existence of a technology should not obscure (a) the impact its maturit...

Objective:Mold contamination of cakes and the possibility of mold growth can pose a serious health problem. Bakery products include various ingredients, which regularly contain molds. These microorganisms on cakes can come from the air, contaminated packaging materials and other sources.Methods: In this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...

  Abstract   Background: The tibial diaphyseal fractures are the most common type of long   bone fractures encountered by most orthopedic surgeons. In accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia   fractures have the second incidence of all tibia fractures after the middle tibia fractures.   The purpose of the study was to asses...

One of the problems electroplating industry is periodic discharge concentrated spent electrolytes together with rinsing wastewater. This leads to irreversible loss valuable components, as well risk heavy metal ions entering environment, which have toxic, mutagenic, and carcinogenic effects. The paper presents research on processing from zinc, nickel, copper, cadmium plating, collected over 3 ye...

Contaminants in plating wastewater are hard to remove, especially hexavalent chromium ions. This waste stream contains a large amount of Cr6+, highly toxic metal, potential cause cancer. To reduce this pollution, sludge from supply water treatment plant (DWTS) has been used make adsorbent. was denaturized by thermal method. After that, synthetic contained Cr6+ treated batch adsorption model wit...

Abstract The article presents the possibility of recovering nickel from waste produced as a result wastewater neutralization during electrochemical surface treatment metals. Leaching sludge with concentrated hydrochloric acid enabled metals contained in precipitate to solution efficiency 74.4% (Se) 100% (Zn). content elements was determined using ICP-OES method. next step precipitation obtained...

New copper plating bath chemisties are being developed to meet the emerging need of plating copper into submicron features on semiconductor wafers. These chemistries are designed to provide a fast, efficient, fill for even the most challenging wafer terrain. It has been found that maintaining the concentration of the additives in these plating baths at certain levels is critical to the performa...
