The exploitation of natural gas deposits also requires the transport extracted fluids through pipelines to their treatment facilities. Usually contain, in addition methane, ethane, liquid fractions propane, butane, hexane and sometimes salt water associated with deposit. Given that delivery for consumption must be carried out without oil liquids, flow rates extraction wells are taken two-phase ...

A pilot-scale evaluation was conducted at the U.S. Environmental Protection Agency (EPA) Test & Evaluation (T&E) Facility in Cincinnati, Ohio, on a multi-layer, cartridge-based system that combines physical filtration with carbon adsorption and ultraviolet (UV) light disinfection to serve as a home-base water treatment security device against accidental or intentional contaminant events. The sy...

this paper addresses a reliable facility location problem with considering facility capacity constraints. in reliable facility location problem some facilities may become unavailable from time to time. if a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. hence, the fail of facilities leads to disruptions in facility location dec...

BACKGROUND The nontherapeutic use of antibiotics in swine feed can select for antibiotic resistance in swine enteric bacteria. Leaking swine waste storage pits and the land-application of swine manure can result in the dispersion of resistant bacteria to water sources. However, there are few data comparing levels of resistant bacteria in swine manure-impacted water sources versus unaffected sou...

A national project for a Swedish Proton Therapy Centre (SPTC) supported by the Swedish university hospitals was formed in 2003. The aim of the SPTC project was to build a national proton therapy centre focused on combining patient treatment and clinical research. The centre was to be operated under the principle of shared governance and distributed competence meaning that the preparations befor...
