Research ArticleOpen accessIn the abstractHydrogeophysics 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 abstractMorphology and Histochemistry of the Corpus Luteum (CL) of Ovaries of Pregnant and Infertile CowsEvgeny Skovorodin, Svetlana Bogolyuk, George Bazekin et al.The purpose of our study is to study the functional morphology of the Corpus Luteum (CL) of the ovaries of pregnant and infertile cows in normal and pathological conditions. For that purpose, the ovaries of cows were examined after slaughter, histological and histochemical examination of the CL was carried out. For the antemortem examination of the ovary, the biopsy method … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 23 Oct 2020 · 6,610 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Approach in Application of the AHP–Fuzzy TOPSIS Method in Mineral Potential Mapping of the Natural Bitumen (Gilsonite): A Case Study from the Gilan-e-Gharb Block, the Kermanshah, West of IranElham Rahimi, Younes Shekarian, Salman Mastri Farahani et al.The Gilan-e-Gharb block is known as a prospective area for hydrocarbon resources in the form of oil, gas in deep potential and natural bitumen (Gilsonite) on the surface. Natural bitumen is not clearly detectable by geochemical or geophysical methods. Hereupon, identifying high potential areas for further exploration, attempted with the help of AHP-Fuzzy and TOPSIS methods. The comprehensive database of … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 2 Mar 2020 · 7,980 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of Organelle Genomes of Extra Nuclear Sunflower Mutants with Variegated PhenotypeIrina Dremuk, Nikolay Kozel, Mariya Logacheva et al.The comparative analysis of complete chloroplast and mitochondrial DNA sequences of the original inbred line 3629 and three extra nuclear mutant lines variegated-1, variegated-15, variegated-17, obtained by the N-nitroso-N-methylurea induced mutagenesis, was done. The studied mutant lines were presented two different phenotypes with diverse chlorophyll content: Pale/green mutant line variegated-17 with 1.8% relative (to 3629 line) chlorophyll content in mutant … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMIC DAYLIGHT AND SOLAR CONTROL IN TROPICAL CLIMATEYaik-Wah LimDaylight is dynamic, thus there is no one common solution for all scenarios. It is more critical in tropical climate where the sky is predominantly intermediate; with inconsistent clouds formations which will influence the presence of direct sunlight and daylight availability. In this study, the potential of dynamic internal shading devices for improving daylighting performances in tropical climate was investigated. … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 29 Apr 2015 · 7,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractPORE-PRESSURE PREDICTION FROM SEIMIC DATA IN PARTS OF THE ONSHORE NIGER DELTA SEDIMENTARY BASINEmujakporue Omokenu GodwinPore pressure prediction in parts of the Onshore Niger Delta Sedimentary Basin using seismic reflection data has been carried out. The Bower’s technique of velocity-to-pore pressure transform was adopted. The seismic velocities were derived from the seismic data using layer cake velocity model and were later compared with the available sonic logs velocities obtained from the area. Parameters in the … …Physics International, Vol. 4, Issue 2 · 20 Mar 2014 · 7,437 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Aquifer Characteristics in Echi, Delta State, Nigeria Using Well Logging and Pumping Test MethodOchuko AnomohanranThis study was carried out to evaluate the aquifer characteristics of groundwater at Echi, Delta State, Nigeria. This was carried out by conducting electrical resistivity and spontaneous potential loggings in a drilled well at the study location. Pumping test using a one kilowatt pumping machine was carried out in the well. The logs were interpreted while the record of the … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent and Future Nanotech Applications in the Oil IndustryCocuzza Matteo, Pirri Candido, Rocca Vera, Verga FrancescaProblem statement: Nanotech applications in the oil industry are not completely new: nanoparticles have been successfully used in drilling muds for the past 50 years. Only recently all the other key areas of the oil industry, such as exploration, primary and assisted production, monitoring, refining and distribution, are approaching nanotechnologies as the potential Philosopher's stone for facing critical issues related … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 10,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalynological Studies of Sediments from North Chioma-3 Well, Niger Delta and its Palaeoenvironmental InterpretationsOlugbenga Ebenezer Ige, Kalyani Datta, Kanak Sahai, Krishna Kumar RawatProblem statement: The Niger Delta Nigeria stands among the world's best-studies delta complexes but its superficial deposits are among the poorest known publicity. In spite of continuous oil prospecting production in the area, there is still a paucity of published information and data on the palynology of the Niger Delta. This study aimed at reconstructing the palaeoenvironments of the Niger … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Mercury Mine Activities on Water Resources at Azzaba-North-East of AlgeriaFadila Alligui, Abdelhak BoutalebProblem statement: Mercury mineralization occurred in Azzaba (north-eastern Algeria) as a part of mercurial Numidian belt, consists of numerous of Hg deposits (Koudiat Sma, Mrasma, Guenicha, Fendek, Ismail and Ras Elma). These deposits are hosted in a variety of lithologies including sandstone, limestone, breccias and conglomerate. The ores occur as cinnabar deposits in Ypresian-Lutetian formations. Although the quantity and type … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,493 accessesView PDFCite
