Dykes, or levees, are structures designed and constructed to keep the water in a river within certain bounds event of flood. In relation with climate change, more frequent floods, higher intensity, can be expected due anthropogenic emissions greenhouse gases into atmosphere. The objective this review paper is address many ways which geosynthetics contribute sustainable construction dykes thus s...

Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. In this study, simple directional vario...

Epitaxial Ag(001) layers were deposited on MgO(001) in order to study electron surface scattering. X-ray reflection indicates 3D layer nucleation with a high rms surface roughness of 1.0 nm for a layer thickness d1⁄4 3.5 nm. X-ray diffraction shows that f111g twins form at d< 11 nm, followed by 2nd generation twinning for 11 nm< d< 120 nm. Increasing the growth temperature from 25 to 150 C supp...

The understanding of the long-term behavior of the RPCs developed as dedicated muon trigger detectors at LHC and presently in construction, is analyzed. The main aging mechanisms are reviewed. The gas contamination by the hydrofluoric acid is analyzed as a possible aging cause and a method for measuring the fluorine concentration in the exhaust gas is described. Finally, the use of RPCs for the...

Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...
