In modern living, rapid development has created an increase in demand for groundwater. An endeavor has been made to understand the hydrogeochemical parameters to determine the utility of groundwater. This situation is severe in coastal hard rock aquifers due to the influence of salinity...

There is growing scientific interest in the potential role that precision irrigation (PI) can make towards improving crop productivity, and increasing water and energy efficiency in irrigated agriculture. Most progress has been made in arid and semi-arid climates for use in high value crop...

Stevia (Stevia rebaudiana Bertoni) is a relatively unknown crop in Europe, with great potential as a natural sweeteners source. Stevia has a high content of sweeteners, which are up to 150 times sweeter than sugar, but virtually with no calories. Stevia can be cultivated as an irrigated summer...

This paper focuses on theory studies of rock electrical properties using percolation theory. The results show that classical site and bond percolation models can well describe the characteristics of the pore connectivity and the effects on the electrical resistivity. Because of the...

A 3-dimensional model for an in-house proton exchange membrane (PEM) fuel cell with serpentine channels has been developed in order to investigate the sensitivity of the fuel cell performance to the anisotropic gas permeability and electrical conductivity of gas diffusion layers (GDLs). For a...

Few studies have focused on the relationship between the various causes of groundwater level fluctuations and the seawater intrusion process, due to the complexity of this relationship, being the aim of this paper. Piezometric fluctuations in coastal aquifers are determined by a number of...

Vanadium-doped ZnTe films of composition 0 to 10wt%V, were prepared onto glass substrate by e-beam evaporation of the element in vacuum at ∼8×10−4Pa. The effects of various deposition conditions on the electrical properties of the films have been studied in detail. The deposition rate of...

Water availability and quality are two fundamental factors for agriculture in arid and semi-arid regions. This study evaluates the effects of a water-permeable, Suspended Shade Cloth Cover (SSCC), on the quality of water stored in an on-farm Agricultural Water Reservoir (AWR). Water quality...
