Interest has increased recently in water recycling and reuse. The possible economic feasibility of reuse and recycling dramatically increases th}complexity of designing a optimal water delivery s stem. In this •a•c•: wc p;csc:.;., ii6,ii•;i,• ..... ud,•i -,ich takes into account both flow requirements and water quality. Because of the model's transshipment formulation the solution technique see...

Although small, rural water supplies may present elevated microbial risks to consumers in some settings, characterizing exposures through representative point-of-consumption sampling is logistically challenging. In order to evaluate the usefulness of consumer self-reported data in predicting measured water quality and risk factors for contamination, we compared matched consumer interview data w...

Due to low cost, ease of administration, and lack need for trained personnel, the oral route is the most convenient and accessible way to design different medicines that could be simply consumed by patients. Regardless of the great benefits of this route, the main challenge in the bioavailability of oral medications is gastrointestinal instability. Nanotechnology is used to improve the solubili...

the aim of this study is to investigate drinking water contamination and to identify potential sources of contamination during the water production, delivery process and in water tanks in the kindergartens of gaza strip governorates. the samples were taken from water tanks in the kindergartens, water tankers and private desalination facilities in the gaza strip and analyzed for chemical and bio...

Fast-disintegrating tablet (FDT) technology is one of the recent innovative technologies in pharmaceutical formulations, and the FDT formulation has become a fast-growing segment in oral drug delivery systems. FDTs can be administered easily without water, although taking water makes oral administration even easier. They are suitable for children, the elderly and anyone who has a difficulty in ...

Intervention: Intervention sites participated in learning collaboratives focused on policy and environmental changes to increase healthy eating, drinking, and physical activity opportunities during afterschool time (materials available at www.osnap.org). Collaboration between Boston Public Schools Food and Nutrition Services, afterschool staff, and researchers established water-delivery systems...

A highly water-soluble macromolecular compound of ursolic acid with monomethoxypoly(ethylene glycol) (mPEG) was prepared. The physicochemical properties and stabilities under different conditions were investigated. By PEG conjugation, greatly increased water solubility was obtained, and the results showed that this conjugate was a potential prodrug for the oral delivery of ursolic acid.

As with most water companies in the world UK water companies face very little competition for the delivery of water within their area. However, recently both the government and the regulator, Ofwat, have indicated that they wish to see a major change in the industry through a significant growth of competition. The pricing of common carriage of water will be central to whether this objective can...

A water-soluble nanocarrier for a photo-activated CO releasing moiety (photoCORM) that can be triggered with NIR excitation is described. This has an upconversion nanoparticle core encapsulated by an amphiphilic polymer imparting both water solubility and a hydrophobic interior containing the photoCORM trans-Mn(bpy)(PPh3)2(CO)2. Such an ensemble offers a unique strategy for CO delivery to biolo...
