Research ArticleOpen accessIn the abstractInvestigating Sintering Mechanisms for Additive Manufacturing of Conductive TracesJasmine McKenzie, Salil DesaiAdditive Manufacturing (AM) processes enable the fabrication of miniaturized and flexible devices on complex geometries. This paper explores a hybrid additive manufacturing technology that integrates micro-extrusion and PICO-jetting methods. Conductive slurries and colloidal inks were optimized for their rheological properties to aid their precise deposition. A variety of conductive materials which include carbon, silver, nano-particle silver and nickel were deposited … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 5 May 2018 · 8,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractSedimentology and Ichnology of Late Oligocene Delta Front Reservoir Sandstone Deposit, Greater Ughelli Depobelt, Niger DeltaRaphael Oaikhena Oyanyan, Michael Ndubuisi OtiSedimentological and ichnological study of cored reservoir sands correlated with wireline logs between two wells, 0.8 km distance apart along dip direction, enabled vertical and cross sectional facies variability assessment aimed at determining intra sand-body continuity in longitudinal or down-dip direction; and sub-environments of deposition and factors that controlled depositional processes. Ten lithofacies described 62 meters cores of the reservoir … …Current Research in Geoscience, Vol. 5, Issue 1 · 30 Jul 2015 · 7,829 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Mechanical Properties of Aluminium Alloy 2024 Reinforced with Silicon Carbide and Fly Ash Hybrid Metal Matrix CompositesM. Mahendra Boopathi, K.P. Arulshri, N. IyanduraiMaterials are frequently chosen for structural applications because they have desirable combinations of mechanical characteristics. Development of hybrid metal matrix composites has become an important area of research interest in Materials Science. In view of this, the present study focuses on the formation of aluminium-Sic-fly ash hybrid metal matrix composites. The present study was aimed at evaluating the physical properties … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 8 Mar 2013 · 28,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable CropsA.E. Ghaly, F.N. AlkoaikProblem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squash). Approach: Each crop … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetabolic Fingerprinting of Three Malaysian Ginger (Zingiber officinale Roscoe) Using Gas Chromatography-Mass SpectromertryH.J. Mahdi, R. Andayani, IshakProblem statement: There is a chemical variation among different ginger cultivars detected by previous studies including the volatile and non-volatile oleo-resins. In this study we try to determine whether these variations are related to a genetic factor rather than environmental or intrinsic factors. Approach: A comprehensive metabolic fingerprinting from the leaves of three micro-propagated ginger cultivars Bukit Tinggi, Tanjung Sepat … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Implication of Poverty Alleviation Programs on Rural Women in Ondo-State Case Study of Country Women Association of NigeriaFasoranti Mary ModupeThe study examined the economic implication of COWAN poverty alleviation programme in rural women. Multi-stage sampling technique was used to select 100 respondents from Ikare and Ugbe from Akoko North East and Oka and Akungba from Akoko South West. The data collected were analysed with the aid of descriptive statistics and simple regression analysis to examine the socio-economic characteristics of … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabric Behavior of Sand in Post-liquefactionSeyed Amirodin SadrnejadAn anisotropic plasticity model for post-liquefaction of the undrained behavior of sand is presented. The model incorporates the critical/steady state concept that postulates the existence of a state where sand continuously deforms at a certain constant effective stress depending two main parameters of both initial bulk parameters (void ratio or relative density) and the stress level (mean stress). The local … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,409 accessesView PDFCite
