BACKGROUND Female sterilisation is the most popular contraceptive method worldwide. Several techniques are described in the literature, however only few of them are commonly used and properly evaluated. OBJECTIVES To compare the different tubal occlusion techniques in terms of major and minor morbidity, failure rates (pregnancies), technical failures and difficulties, and women's and surgeons...

Groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. This study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...

Small, low-income, and rural communities across the United States are disproportionately exposed to arsenic contaminated drinking water because existing treatment solutions too expensive difficult operate. This paper describes efforts overcome some barriers limitations of conventional iron electrocoagulation (Fe-EC) enable its use in Californian (U.S.) context. Barriers Fe-EC's application Cali...

Itai and Rodeh [IR] have proved thal for any 2-conncctcd graph G and any vertex S E G there are two spanning trees such that the paths from any othcr vcrtex to s on the trees are disjoint. In this p,aper the result is generalized to 3-connected graphs. T ec hn io n C om pu te r Sc ie nc e D ep ar tm en t T eh ni ca l R ep or t C S0 46 2 19 87 -1

Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...

Electrocoagulation is a method that can be used to remove pollutants and nutrients from liquid waste. This has been found for long time but exclusively recently developed wastewater treatment after lengthy process. colloidal materials, i.e., suspended solids, metals, other dissolved solids in wastewater. Several studies have shown electrocoagulation successfully operated various industrial wast...
