Research ArticleOpen accessIn the abstractContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,796 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 · 14,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractSEDIMENTARY FACIES AND DEPOSITIONAL ENVIRONMENTS OF CENOZOIC SEDIMENTARY FORMATIONS CROPPING OUT AT THE CENTRAL PART OF THE DOUALA BASINBachirou Mfayakouo Chavom, Pierre R. Njike Ngaha, Dieudonné L. BitomThe Douala Basin is one of three units of the Cameroonian coastal basin in the Gulf of Guinea, formed from the east-west extension between African and South American plates generated during the opening of South Atlantic in the Early Cretaceous. This basin contains sediments from Lower Cretaceous to present. The Cretaceous depositional environments are well understood whereas there is very … …Current Research in Geoscience, Vol. 4, Issue 1 · 6 Jan 2015 · 7,940 accessesView PDFCite

EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Mixed Organic and Inorganic Fertilizers Application on Soil Properties and the Growth of Kenaf (Hibiscus cannabinus L.) Cultivated on Bris SoilsMohd Hadi Akbar Basri, Arifin Abdu, Shamshuddin Jusop et al.The demand for kenaf in the world increases rapidly by the years. Cultivation of the crop in Malaysia is a challenging task, especially when kenaf is grown on sandy soils with low fertility, such as the BRIS Soils (Beach Ridges Interspersed with Swales). A pot study was conducted in a glasshouse at Universiti Putra Malaysia to evaluate the potential of … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 8,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoluble CD59-Antigen Levels are Increased in Renal Disease PlasmaOluseyi Adewale VanderpuyeCluster of Differentiation antigen 59 (CD59) is a glycosyl phosphatidylinositol-linked protein that protects cells from damage by lytic terminal complexes of complement. Soluble forms of CD59 in serum have been little investigated in disease states. In the present study, by using a sandwich ELISA, reactivities with antibodies to CD59 were compared for sera and plasma from normal individuals and those … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 6,946 accessesView PDFCite
