Research ArticleOpen accessIn the abstractAssessing and Improving the Performance of Grouted MacadamMomtaz M. Othman, Ahmed Ebrahim Abu El-Maaty, Zeinab S. HusseinThere are many road defects appear in flexible pavement layers. Rutting, raveling and cracks are considered the main problems in Egypt. Using grouted macadam system as a surface asphaltic layer (or called Semi-Flexible Pavement (SFP)) has many advantages such as saving the natural asphalt and enhancing the performance against deteriorations. The main scope of this research is to evaluate and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemistry of Siloam and Tshipise Geothermal Springs, Limpopo Province, South AfricaOlatunde Samod Durowoju, John Ogony Odiyo, Georges-Ivo Ekosse EkosseGeothermal springs are natural geological phenomena that occur throughout the world, and South Africa (SA) is endowed with several springs of this nature. Most of the geothermal springs in SA (31%) are found in Limpopo Province. Assessment of geochemistry of Siloam and Tshipise geothermal springs were undertaken during 2014 winter (May – July) and summer (October – December) seasons. Water … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Mar 2018 · 8,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrophysical Properties Distribution Modelling of an Onshore Field, Niger Delta, NigeriaGodwin Omokenu EmujakporueThis research is based on the modelling of petrophysical parameters distribution of an onshore oil field in Niger Delta. The methodology involves the construction of 3-D grids that represent the reservoir geometry, accompany by property modeling where the 3-D grids were populated with petrophysical properties (porosity, water saturation, net to gross ratio, facies and permeability). The objective is to construct … …Current Research in Geoscience, Vol. 7, Issue 1 · 3 Apr 2017 · 14,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrophysical Characterization and Flow Models for Agbada Reservoirs, Onshore Niger Delta, NigeriaPrince Suka Momta, John Owate Etu-Efeotor, Charles Ugwu UgwuezeThree selected reservoirs (XB, XC and XE) from three wells (A, B and C) occurring within the Agbada producing sands in part of the Greater Ughelli Depobelt of the onshore Niger Delta have been studied. The study aims at evaluating the petrophysical characteristics of the sand-bodies and also identifies the various flow units present within each reservoir. Petrophysical parameters were … …Current Research in Geoscience, Vol. 5, Issue 2 · 21 Oct 2015 · 7,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractSedimentology and Depositional Environment of D2 Sand in Part of Greater Ughelli Depobelt, Onshore Niger Delta, NigeriaPrince Suka Momta, Jonathan O. Omoboh, Minapuye I. OdigiThe sedimentology and depositional environment of D2 sand in part of the Greater Ughelli depobelt have been studied using well logs and core data. Three wells were correlated to establish the lateral continuity of the D2 sand across the field and standard gamma ray log trends was used to infer depositional environments. Cored section of well B was described to … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 19 Sep 2015 · 8,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractCATION-EXCHANGE MEMBRANES WITH POLYANILINE SURFACE LAYER FOR WATER TREATMENTDinar Dilshatovich Fazullin, Gennady Vitalevich Mavrin, Michael Pavlovich SokolovIon-exchange membranes are widely used in modern technologies, particularly in the field of water treatment and make it possible to considerably reduce expenses for wastewater treatment and ensure high degree of purification. Currently, perfluorinated sulfated proton-conducting membranes are often used, such as NAFION and its Russian analogue, MF-4SK based on co-polymerization product of a perfluorinated vinyl ether with tetrafluoroethylene. However, … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 13 Sep 2014 · 7,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractPurification of Natural Gas with Impurities using Membrane Processes: Parameter EstimationN. W. Jusoh, K. K. Lau, A. M. ShariffProblem statement: Membrane processes have received a significantly high attention on natural gas separation processes since this technology provides higher operating and cost advantages as compared to other technologies. One of the major problems related to natural gas separation using membrane is the existence of feed impurities including CO2, heavy hydrocarbon and water. Approach: Hence, mathematical model that is able … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 22 May 2012 · 8,426 accessesView PDFCite
Research ArticleOpen accessIn the abstractPermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvantages of Utilizing Geotextiles in Fixing Sandy Soils and Increasing Shear Strength in Water Conveyance TrenchesAlireza Mardookhpour, Leila OoshaksaraieWith the increasing demand in water supply and either for generation or for irrigation and human consumption, water conveyance structures must guarantee a maximum efficiency at the lowest construction and maintenance costs. Using thin geotextiles allow very low permeability and very high transmissivity. Conclusion/Recommendations: The system constructs a continues, low roughness on the entire section of canal.
