in this study, the feasibility of using magnetic technology to reduce the dispersion of soil has been investigated. the reference treatment was potable water and 3 magnetic water devices (with different magnetic intensities) were used for magnetizing the potable water. the results showed that the magnetic field has a significant effect in order of 5 percent on increasing of magnesium concentrat...

dispersive soils are prevailent in many parts of the world, including in iran. construction of hydraulic structures on dispersive soils has created various serious problems. since it is neither economical nor justified to replace a dispersive soil with a non-dispersive one, there fore stabilization of a dispersive soil in one way or another is indispensable and unavoidable. throughout this rese...

filter is one of the main components of embankment dams. by a simple but effective performance, filter protects the dam against erosion and soil scouring in impervious core caused by leakage (piping) and makes it safe. interaction between filter and erodible base soil is a complex phenomenon which is dependent upon several factors, and has challenged researchers for better understanding the fil...

Liquids coming from different sources like wastewaters, agricultural and industrial activities and leakages of chemical substances often have high concentration of chemical compositions and the osmotic gradient generated around such sources causes a considerable transmission of the Contamination. The steam transmitted by non-polluted soils moves to polluted masses, causing an increase in the vo...

A three-dimensional (3-D) time-domain numerical scheme for simulation of ground penetrating radar (GPR) on dispersive and inhomogeneous soils with conductive loss is described. The finite-difference time-domain (FDTD) method is used to discretize the partial differential equations for time stepping of the electromagnetic fields. The soil dispersion is modeled by multiterm Lorentz and/or Debye m...

Internal erosional behaviour of lignosulfonate treated dispersive clay has been studied using the Process Simulation Apparatus for Internol Crack Erosion (PSAICE) designed and built at UOw. Effectiveness of Iignosulfonate treated dispersive clay on the erosion resistance has been investigated and its advantage over traditional admixtures is presented. Test results show that the hydraulic shear ...

thallium is widely found in nature, but the only inorganic stones full of this element are crookesite and lorandit. it isalso found in pyrites of copper, lead and inorganic stones. the element and its compositions are toxic and harmful to theenvironment; therefore, its application requires caution and further research. it is important to develop sensitive andaccurate analytical methods to deter...

A simple, rapid, efficient, and environmentally friendly method for the determination of five triazine herbicides in water and soil samples was developed by using dispersive liquid-liquid microextraction (DLLME), coupled with high performance liquid chromatography-diode array detection (HPLC-DAD). The water samples were directly used for DLLME extraction. For soil samples, the target analytes w...
