08319 - Long Term Corrosion Performance of Soil Reinforcement in Mechanically Stabilized Earth Walls
Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates ...
The influence of the addition of carbon on the crystalline structure and resistivity of polycrystalline silicon layers grown by simultaneous decomposition of SiH,, C^H. a n d P H T a t '°"° c w a s studied. Carbon content, morphology, preferred orientation, crystallite size, lattice strains and resistivity were determined. It was found that carbon has a pronounced effect on the crystalline stru...
Continuous vertical electrical sounding (CVES) surveys were carried out on KNUST campus to ascertain the electrical properties of the formations in the area in order to determine its suitability for the construction of heavy structures. Eight 2D CVES profiles were conducted at the site in the study area with a wenner array using electrode separations of 1, 2.5 and 4 m. The apparent resistivity ...
A central loop Transient Electromagnetic TEM Resistivity Survey was conducted at the Geysir high temperature geothermal area as part the project of the author. The area is situated 110 km away from Reykjavik and lies in a shallow valley elongated north-south. Geologically it is surrounded by three volcanic domes made-up of rhyolites, hyloclastites and inter-glacial basaltic lava that obtain hea...
Regional development in Panimbang District, Banten Province, Indonesia, is executed so that the tourism area not centered solely on west coast of Pandeglang but also surrounding area. The carried out stages from government offices, education facilities, and public facilities. One facilities to be built a garden. This study aimed evaluate condition soil layers fertility for garden construction. ...
We report magnetotransport investigation of nonmagnetic InSb single crystal doped with manganese at Mn concentration NMn ~ 1,5 × 10(17) cm(-3) in the temperature range T = 300 K-40 mK, magnetic field B = 0-25T and hydrostatic pressure P = 0-17 kbar. Resistivity saturation was observed in the absence of magnetic field at temperatures below 200 mK while applied increasing external magnetic field ...
Since the observation of the first brown dwarf in 1995, numerous studies have led to a better understanding of the structures of these objects. Here we present a method for studying material resistivity in warm dense plasmas in the laboratory, which we relate to the microphysics of brown dwarfs through viscosity and electron collisions. Here we use X-ray polarimetry to determine the resistivity...
Electrical resistivity evolution during precipitation in Al-Sc alloys is modeled using cluster dynamics. This mesoscopic modeling has already been shown to correctly predict the time evolution of the precipitate size distribution. In this work, we show that it leads too to resistivity predictions in quantitative agreement with experimental data. We only assume that all clusters contribute to th...
Cracks have been developed in a large lecture hall on the University of Mosul Campus. These cracks exist along two sides building. Multi Analysis Surface Wave and Electrical Resistivity Tomography surveys were conducted at surrounding building to investigate nature distribution shallow subsurface soil/rock. The MASW’s data show three layers: first layer is characterized by low shear wave veloci...
We have prepared Gd,-IPrXBa,Cu,O,-, phase spread alloy thin films with well-defined variations in the concentration of Pr across a single substrate. Their Pr concentrations were independently determined from electrical resistivity and Auger electron spectroscopy measurements. The results from both methods are in good agreement with each other. Using this technique several high-temperature super...
