Unburned carbon (UC) is the major source of organic contaminants in municipal solid waste (MSW) fly ash. So most organic contaminants can be removed by the removal of the UC from the MSW fly ash. In this paper, we first used a technique of column flotation to remove UC from MSW fly ash. The influences of column flotation parameters on the recovery efficiency of UC were systematically studied. I...

BACKGROUND Although there are limited numbers of incidence and persistence estimates for anal human papillomavirus (HPV) in women and in men who have sex with men (MSM), there are no such reports for men who have sex with women (MSW). METHODS Genotyping was performed on anal samples from men, aged 18-70, from São Paulo, Brazil; Cuernavaca, Mexico; and Tampa, Florida, who provided specimens at...

Municipal Solid Waste (MSW) is complex refuse consisting of various materials with different properties. Some of the components are stable while others degrade as a result of biological and chemical processes. Leachate resulting from this is hazardous pollutant to the soil and ground water underlying. Leaching of this leachate and heavy metals into the soil leads to the contamination of both so...

The current research focuses on assessing the potential of municipal solid waste (MSW) conversion into biofuel using pyrolysis process. MSW samples were taken from Zaatari Syrian Refugee Camp. physical and chemical characteristics studied proximate elemental analysis. results showed that moisture content is 32.3%, volatile matter (VM) 67.99%, fixed carbon (FC) 5.46%, ash 24.33%. analysis was co...

Collection of Municipal Solid Waste (MSW) accounts for a significant proportion of most municipal budgets, and has drawn some degree of researchers‟ interest. This study was conducted in Ota, Southwest Nigeria, to explore the use of Visual basic program as an innovative tool to select the most economic haulage system among three systems found in literature (conventional-, modified- and Stationa...

BACKGROUND Little is known about the epidemiology on human papillomavirus (HPV) infection among HIV-infected men in Korea. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among HIV-infected men in Korea. METHODS A single-center cross-sectional study was conducted with HIV-infected men in Korea. Participants...

Mr. Don Walter should be commended for his technical paper dealing with the real-world problems of preparing anaerobic digester feeds from a difficult raw material, municipal solid waste (MSW). The information presented in the paper is not readily available in the published litera­ ture, and will be valuable to engineers interested in MSW processing and digestion. The author discusses some of t...

Various theoretical uncertainties in the standard solar model and in the Mikheyev-Smirnov-Wolfenstein (MSW) analysis are discussed. It is shown that two methods of estimating the solar neutrino flux uncertainties are equivalent: (a) a simple parametrization of the uncertainties using the core temperature and the nuclear production cross sections; (b) the Monte Carlo method of Bahcall and Ulrich...
