agriculture sector is the main consumer of water in the world. in productive sectors likeagriculture, water is considered as a valuable mediatory commodity or production input.demand for agriculture water comes from consumers› (agriculture products›) behavior. thisstudy aims to evaluate water use optimality in pomegranate arbors at the charkhab village inthe yazd province. the data was randomly...

The objective of this research was to check whether the observed low-density water (LDW) to high-density water (HDW) transformation does take place or not in a complex aqueous system like those involved in high pressure processing of food. In-situ measurements of speed-of-sound up to 640 MPa were used for this purpose. After validation of the methodology in liquid water at 25 oC, LDW-to-HDW tra...

In order to promote the selective water permeation through porous filler, hydrophilic MOF-801 crystals with superior water adsorption ability were incorporated into chitosan (CS) matrix to fabricate MOF-801/CS mixed matrix membranes (MMMs) for pervaporation dehydration of ethanol. Both the experimental and molecular simulation results confirm the selective adsorption of water molecules in MOF-8...

background: contamination of water by toxic chemicals has become commonly recognized as an environmental concern. based on our clinical observation in mashhad, northeastern iran, many people might be at risk of exposure to high concentrations of toxic heavy metals in water. because wastewater effluents as well as water wells have been commonly used for irrigation over the past decades, there ha...

MOORE, L.J.; RUGGIERO, P., AND LIST, J.H., 2006. Comparing mean high water and high water line shorelines: Should proxy-datum offsets be incorporated into shoreline change analysis? Journal of Coastal Research, 22(4), 894– 905. West Palm Beach (Florida), ISSN 0749-0208. More than one type of shoreline indicator can be used in shoreline change analyses, and quantifying the effects of this practi...

reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

Water resources development options are usually selected on a least-cost basis. While economic considerations are dominant in choosing projects, there are also a mix of other factors including social demands, political expediency, social equity, and environmental considerations that impact final decisions and development of water supply systems. Understanding local priorities in water resource ...

The concentrations of naturally occurring radionuclides of Ra and Ra were determined in the groundwater samples in three areas near Riyadh city in Saudi Arabia. The waters of these areas are supplied for the city consumption. A total of thirty water samples of the three areas were analyzed for Ra and Ra. The concentration of Ra was found in the range from 2.1 – 6.3, 7.2 14.1 and 16.7 – 33.5 mBq...
