One of the most important and toxic heavy metals in wastewater is chromium. Cr (VI) is released from different industrial operations, including metallurgy, leather tanning, paint, textile industries, chemical manufacturing, pulp production, ore and petroleum refining, metal corrosion, electroplating products etc. Hexavalent chromium is toxic, carcinogenic, probably mutagenic and highly soluble....

A genetic algorithm (GAHCA) is proposed to control elevator groups of professional buildings. The genetic algorithm is compared with the universal controller algorithm in industry applications. In other to do so an ARENA simulation scenario has been generated during heavy lunchpeak traffic conditions. The results allow us to affirm that our genetic algorithm reaches a better performance attendi...

The study presents a performance evaluation model that does not only concentrates on financial performance, but also on company size, macro -economic, and industry related factors as well. The developed model considers four construction contacting categories: (1) general building; (2) heavy; (3) special trade; and (4) real estate. It also considers the effect of company size, along with economi...

This Fact Sheet covers the start of the nuclear industry chain – uranium mining. It aims to present a concise overview of the nature of uranium, its mining and milling, and the numerous environmental and radiological aspects associated with this heavy industrial endeavour. It is clear that uranium is a finite resource and that the environmental costs associated with mining are significant and m...

Traditional development approaches (particularly in fixed price, outsourced projects) are normally based on a contractuallyfixed set of requirements and relatively heavy change-control processes. Movements in the IT industry to formulate new development approaches to match more realistic business scenarios where requirements are continually refined and updated in the course of a project, have r...

Korea is one of a few countries that have achieved significant economic growth in the recent two decades. The early agricultural economy in 1940s and 1950s had gradually changed due to the government-driven economic development plans started in 1960s. The early emphasis was made on both modernization of the agricultural industry and the promotion of the heavy and chemical industry. After seeing...

The prevalence of various pollutants like nitrogenous, sulphurous, phosphorous compounds, heavy metals, and organic compounds has seriously threatened the sustainability of natural ecosystems and is thus interfering with the natural biogeochemical cycling. Chemical pollution of water bodies can cause serious damage to environmental quality because many of these pollutants are extremely toxic an...

Vegetable fields near villages in China are suffering increasing heavy metal damages from various pollution sources including agriculture, traffic, mining and Chinese typical local private family-sized industry. 268 vegetable samples which included rape, celery, cabbages, carrots, asparagus lettuces, cowpeas, tomatoes and cayenne pepper and their corresponding soils in three economically develo...
