An approximate solution of the D-dimensional Schrödinger equation with the modified Pöschl-Teller potential is obtained with an approximation of the centrifugal term. Solution to the corresponding hyper-radial equation is given using the conventional Nikiforov-Uvarov method. The normalization constants for the Pöschl-Teller potential are also computed. The expectation values of (r-2) and (V(r)) are also obtained using the Feynman-Hellmann theorem. © 2010 Chinese Physical Society and IOP Publishing Ltd.

Objective: To provide information on the challenges of haemodialysis in a resource limited setting in South-Western Nigeria. This is a 5 year audit of all haemodialysis sessions carried out at the renal unit of the Ladoke Akintola University Teaching Hospital (LAUTECH), Osogbo, Nigeria. A total of 225 patients were offered haemodialysis (HD) during this period with age range of 10 to 85 years (mean age of 49 years±16.25). There were 155 males and 70 females (male to female ratio of 2.2:1). Chronic kidney failure accounted for 180 (80%) of the cases while acute kidney injury (AKI) constituted 45 (20%) of the cases offered haemodialysis. The sessions of HD in both cases ranged from 1 to 27 with an average of 3 sessions. Hypotension is still the commonest intradialytic complication at our setting while diabetic nephropathy is rapidly emerging as a major cause of end stage renal disease at our setting requiring HD. As seen in other parts of the tropics sepsis, nephrotoxins and pregnancy related cases still accounted for a large percentage of AKI cases requiring haemodialysis. Only three patients were able to afford haemodialysis support for more than three months. Haemodialysis still remains a veritable option in renal replacement therapy. Problems encountered were similar to many other settings in the tropics. Intensive efforts should still be geared at preventing the risk factors for both acute kidney injury and chronic kidney disease in our environment.

Owing to the inefficiency of the conventional primary and secondary recovery methods to yield above 20-40% of the OOIP (original oil in place) as incremental oil, the need for EOR (Enhanced Oil Recovery) techniques to recover a higher proportion of the OOIP has become imperative. ASP (Alkaline/Surfactant/Polymer) is one of such techniques that has proven successful due to its ability to improve displacement and sweep efficiency. Alkaline-surfactant-polymer (ASP) flooding is a combination process in which alkali, surfactant and polymer are injected at the same slug. Because of the synergy of these three components, ASP is widely practiced in both pilot and field operations with the objective of achieving optimum chemistry at large injection volumes for minimum cost. Despite its popularity as a potentially cost-effective chemical flooding method, it is not without its limitations. This paper therefore focuses on the reviews of the application of ASP flooding process in oil recovery in the petroleum industry and its limitations in maximizing oil recovery from onshore and offshore reservoirs. Also discussed are technical solutions to some of these challenges. © 2014 Elsevier Ltd.

Complete oxidation or combustion of any carbon-based organic matter produces CO2, which is known to cause global warming and climate changes. To mitigate the concentration of CO2 in the atmosphere various strategies have been implemented such as separation, storage, and valorization of CO2. The focus of this review was on the catalytic processes of the chemistries involved in the conversion of CO2 into value-added products. The various valorization technologies which include conversion of CO2 into fuel, valorization of CO2 as a feedstock for chemicals were discussed. Also, an overview regarding the challenges and opportunities for future research in CO2 valorization was provided. © 2012 Elsevier Ltd. All rights reserved.

Carbon capture from point source emissions has been recognized as one of several strategies necessary for mitigating unfettered release of greenhouse gases (GHGs) into the atmosphere. To keep GHGs at manageable levels, large decreases in CO2 emissions through capturing and separation will be required. This article reviews the possible CO2 capture and separation technologies for end-of-pipe applications. The three main CO2 capture technologies discussed include post-combustion, pre-combustion and oxyfuel combustion techniques. Various separation techniques, such as chemical absorption, physical absorption, physical adsorption, cryogenics, membrane technology, membranes in conjunction with chemical absorption and chemical-looping combustion (CLC) are also thoroughly discussed. Future directions are suggested for application by oil and gas industry. Sequestration methods, such as geological, mineral carbonation techniques, and ocean dump are not covered in this review. © 2010 Elsevier Ltd. All rights reserved.
