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 · 7,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Erosion Hotspot Area using GIS and MCE Technique for Koga Watershed in the Upper Blue Nile Basin, EthiopiaTewodros T. Assefa, Manoj K. Jha, Seifu A Tilahun et al.Soil erosion is a serious threat in Ethiopian highlands. Continuous land degradation resulted in loss of fertile top soil leading to low agricultural productivity. In addition, excessive soil erosion from Koga Watershed in upper catchment to an artificial reservoir (Koga Dam reservoir) is substantially reducing its service life. Community participatory based effective watershed management strategies may have tremendous potential to … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 10 Sep 2015 · 9,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractOPTIMAL RESOURCE ALLOCATION FOR LAYERED VIDEO MULTICASTING IN WIMAXHung-Yi Teng, Chun-Hung Wu, Ren-Hung HwangReal-time video disseminations over wireless links such as video telephony, video conferencing and mobile TV have become fast growing applications. In order to cope with the increasing users' demand, a new scalable and efficient wireless distribution platform is needed. With numerous advantages such as QoS assurance, high data rate and wide coverage, WiMAX has been regarded as an ideal choice … …Journal of Computer Science, Vol. 10, Issue 12 · 24 Dec 2014 · 7,412 accessesView PDFCite
Research ArticleOpen accessIn the abstractAIR POLLUTION AND CLIMATE CHANGE IN LAGOS, NIGERIA: NEEDS FOR PROACTIVE APPROACHES TO RISK MANAGEMENT AND ADAPTATIONAkinola A. Komolafe, Suleiman Abdul-Azeez Adegboyega, Adeleye Y.B. Anifowose et al.The significance of air pollution as one of the contemporary issues and accelerating factors that propel climate change in both developed and developing countries cannot be overemphasized. The problem of air pollution has seemingly become intractable with the incessant failure of both global and local environmental policies purportedly emplaced to address its devastating trend, particularly in growing megacities of the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 12 Jul 2014 · 10,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE PREVALENCE OF DEPRESSION AND ITS RISK FACTORS AMONG MALAY ELDERLY IN RESIDENTIAL CARER. Normala, C. Azlini, M. J. Nurul, Z. M. LukmanThe motivation for the study is to improve the quality of life for elderly in residential care particularly the mental health aspect. Hence, the aim of this study is to examine the prevalence of depression and to identify risk factors related to depression among Malay elderly in residential care. Changes in social structure and economic status have shifted the direction … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 3 Jul 2014 · 7,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractFORCED CONVECTION HEAT TRANSFER, FLOW CONFIGURATION AND THERMAL PERFORMANCE IN A SQUARE CHANNEL WITH MODIFIED V-SHAPED BAFFLESAmnart Boonloi, Withada JedsadaratanachaiThe influences of modified V-shaped baffle in a square channel for heat transfer and thermal performance enhancement are presented numerically in three Dimensional (3D). The V-shaped baffles are modified in order to comfortable to installation in the square channel. The plates are used for clamping on both the upper and lower V-shaped baffles resulting the modified V-shaped baffle like orifice … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 7 Apr 2014 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstract3D Numerical Study on Laminar Forced Convection in V-Baffled Square ChannelAmnart Boonloi, Withada JedsadaratanachaiThe article presents a mathematical study of fully developed periodic laminar flow visualization and heat transfer characteristics in an isothermal wall square-channel fitted with V-shaped baffles on one wall. The computations based on the finite volume method together with the SIMPLE algorithm have been performed. The investigation covers a range of Re based on the hydraulic diameter of the channel, … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,314 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Key Management Technique for Wireless Body Area NetworksVenkatasubramanian Sivaprasatham, Jothi VenkateswaranIn Wireless Body Area Networks (WBAN), the key factors to be considered for transmission of confidential data are security and privacy as it is mostly having applications in emergency medical response systems. The lack of security may lead to loss of data privacy resulting in an adversary to bring in bogus data or altering the legal ones. Hence in this … …Journal of Computer Science, Vol. 8, Issue 11 · 5 Sep 2012 · 7,206 accessesView PDFCite
