Research ArticleOpen accessIn the abstractEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on Suction-rainfall Response of a Cut Slope in Unsaturated Residual Soil Using a Field Rain SimulatorBujang B.K. Huat, Faisal Hj. Ali, S. MariappanThis research describes the design and construction of an artificial rain simulator system and the results obtained with regards to suction-rainfall response of a cut slope in unsaturated residual soil of weathered sandstone of various weathering grades. From the field measurements, the shallow tensiometers are found to record an immediate initial increase in matric suction within the first 20 min … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,271 accessesView PDFCite
