The scientific disposal of Municipal Solid Waste (MSW) is of great significance to the urban ecological environment and the residents’ health. Taking into account the economic, technical, environmental, social indicators, as well as their subindicators, analyzing fourteen evaluation factors, the paper discusses four kinds of disposal methods of MSW using AHP and Fuzzy comprehensive evaluation. ...

BACKGROUND According to the WHO/UNICEF Joint Monitoring Programme (JMP) for water supply and Sanitation definition, safe child feces disposal practices include: children defecation into a latrine, disposal of child stools in a latrine or burial. Inappropriate disposal of human feces including unsafe child feces disposal facilitates the transmission of pathogens. However, the factors associated ...

Almost all major nuclear operations produce residues containing radioactive materials; in reactor operations, for example, the fission products, new elements (such as plutonium) produced by neutron irradiation and the unfissioned nuclear fuel are all radioactive. Some of this material can be put to further use: useful radioisotopes, for instance, can be extracted from the fission products and p...

Premature disposal of female calves before reaching milch herd and undesirable disposal of lactating cows are the major constraints in achieving larger herd size. During the early lactations, younger cows are supposed to give higher milk yield and undesirable disposal of early calvers, thereby, greatly hampers profitability of a dairy farm. Knowledge of the incidence of disposal along with reas...

Coal bed natural gas (CBNG) produced water is usually disposed into nearby constructed disposal ponds. Geochemistry of produced water, particularly trace elements interacting with a semiarid environment, is not clearly understood. The objective of this study was to collect produced water samples at outfalls and corresponding disposal ponds and monitor pH, iron (Fe), aluminum (Al), chromium (Cr)...
