Research ArticleOpen accessPhrase in the titleThe Effects of Cement Kiln Dust on the Soil Electrical ResistivityHamid Ranjkesh Adarmanabadi, Arezou Rasti, Mehrdad RazaviElectrical resistivity is a non-destructive, cost-effective and sensitive method to evaluate soil's physical and chemical properties. Electrical resistivity has been used widely in surface and subsurface exploration. The electrical resistivity is directly related to the subsurface geotechnical and geothermal properties like porosity, temperature, salinity and water content. Recently uses of waste material as an additive to improve the soil engineering … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 14 Jan 2021 · 7,272 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMagnetic Properties and Electrical Resistivity of Zr4+ Substituted Li-Zn FerriteA. A. Sattar, H. M. El-Sayed, W. R. Agami, A. A. GhaniThe effect of Zr-substitution on the physical and magnetic properties of Li0.3+0.5xZn0.4ZrxFe2.3-1.5xO4 ferrites (x=0.0, 0.01, 0.02, 0.03 and 0.05), prepared by the standard ceramic method, has been studied. It is found that the saturation magnetization increases up to x=0.02 and then it decreases. On the other hand, the initial permeability increased while the Curie temperature remained almost constant with increasing … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 8,340 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEstimation of Soils Electrical Resistivity using Artificial Neural Network ApproachKpomonè Komla Apaloo-Bara, Adekunlé Akim Salami, Mawugno Koffi Kodjo et al.The knowledge of the ground electrical resistivity is essential to ensure the protection of electrical and telecommunications networks. However, the monitoring of its values is an expensive task which takes long time. Therefore, its prediction is important. This study investigates on predicting soil electrical resistivity using Artificial Neural Networks. Nine sites of our city (Lome, TOGO) were considered. After characterization … …American Journal of Applied Sciences, Vol. 16, Issue 2 · 13 Mar 2019 · 9,518 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHydrogeophysics Exploration Approximately Ain Al Atti (Region of Southeast Erfoud Morocco)Dakir Ibrahim, Benamara Ahmed, Aassoumi Habiba et al.Electrical resistivity and Very Low Frequency electromagnetic profiles (VLF) were introduced for a litho-structural study in the locality of Douira, located in the Errachidia basin. The electrical reading was carried out with a Schlemberger type device. The VLF profiles were implemented with a different length reaching 1600 m and profile lines oriented in the direction NNW-SSE and N-S. The VLF … …Current Research in Geoscience, Vol. 10, Issue 1 · 16 Dec 2020 · 10,741 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGEOPHYSICAL AND LABORATORY STUDIES OF THE SPREAD AND QUALITY OF THE ODUKPANI LIMESTONE DEPOSITT. E. Chidomerem, A. E. Akpan, I. O. AkpanThe Odukpani limestone deposit has been investigated using geophysical and laboratory techniques with the aim of generating information on its spread and quality. Information generated from the analyses of twenty-six Vertical Electrical Soundings (VES) and core drilling data were used in the study. The VES data were acquired in both grid and random patterns in the immediate area of the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 20 Jun 2014 · 7,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeophysical and Geological Studies of the Spread and Industrial Quality of Okurike Barite DepositAnthony E. Akpan, Ebong D. Ebong, Stephen E. Ekwok, Sackey JosephInvestors have been avoiding the Okurike Barite due to paucity of information on its economic worth in spite of the high demand for barites by the local industries. This study was embarked upon to determine the spread and industrial quality of the barite deposit in order to bridge the information gap. The Okurike Barite mineralised site was investigated using geophysical … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 22 Dec 2014 · 7,256 accessesView PDFCite
