of which was the fact that throughout the operations on the Western Front there was no epidemic of any water-borne diseases. Bearing in mind that in a large number of instances the ordinary sources of supply were either rendered useless or totally destroyed, and that to make up the deficiency drinking water for the armies had to be taken haphazard from streams, canals and rivers, the entire suc...

For many ground water modeling applications, the time and effort spent on preprocessing of input data and postprocessing of output results may far exceed that spent on other project activities. Since the early 1990s, several graphical user interfaces that greatly facilitate the preand postprocessing tasks have become available and have been continually improved. Ground Water Vistas (GWV) is one...

Environmental safety in multi-district boundary regions has been one of the focuses in China and is mentioned many times in the Environmental Protection Act of 2014. Five types were categorized concerning the risk sources for surface water pollution in the multi-provincial boundary region of the Taihu basin: production enterprises, waste disposal sites, chemical storage sites, agricultural non-...

This research is aimed at analizing the effect of environmental management policy implementation on water pollution control to improve the environmental quality. The analytical method used is this study is a literature review that uses effectual causal analysis approach based on literature review, with the object of research conducted in Garut District, Indonesia. The result of discussion shows...

It has been suggested that the significant differences that still persist between the measurements of earth’s radiation budget and the predictions are partially due to the inadequacies in the absorption coefficients of water vapor used in the calculations. Water in all its three phases has a profound influence on both the longwave and shortwave streams of radiation, because of its strong absorp...

Marinas are not reported by states, territories, or tribes to be a major source of nonpoint pollutants that contribute to poor water quality, as are sources such as agriculture and urban areas, though the location of marinas at the water’s edge can lead to their being affected by other pollutant sources. Pollutants from upstream point and nonpoint sources in a watershed might flow to a marina’s...

Researchers conducted a final comparison of dental caries experience between the two communities prior to fluoridation. They sought to compare the mean dmft and dmfs indices, missing teeth, lifetime experience of dental caries and prevalence of toothache, extractions and general anesthesia for extractions between a continuously fluoridated area over the past 25 years (1976-1994) to a non-fluori...

The exquisite selectivity and unique transport properties of membrane proteins can be harnessed for a variety of engineering and biomedical applications if suitable membranes can be produced. Amphiphilic block copolymers (BCPs), developed as stable lipid analogs, form membranes that functionally incorporate membrane proteins and are ideal for such applications. While high protein density and pl...

With more than a billion people lacking accessible drinking water, there is a critical need to convert nonpotable sources such as seawater to water suitable for human use. However, energy requirements of desalination plants account for half their operating costs, so alternative, lower energy approaches are equally critical. Membrane distillation (MD) has shown potential due to its low operating...

The Azores Water Plan (AWP) came to force in year 2003 in order to provide a coherent set of measures to protect and enhance water resources in the archipelago. The AWP was developed according to EU Water Framework Directive (WFD) and a close relationship can be found between goals on both documents. The evaluation of results associated to AWP implementation, made possible through a consultatio...
