This paper examined the long-run and short-run relationship between gasoline price and sectoral output in Nigeria for the period from 1980 to 2010. Six sectors (agriculture; manufacturing; building and construction; wholesale and retail; transportation and communication) of the economy were examined. The long run regression estimate showed that gasoline price is a significant determinant output in all sectors examined with exception to the building and construction sector while the short run error correction estimate revealed that only output of the agriculture and the manufacturing sectors of the Nigerian economy is affect by gasoline price increase in the short run. The study recommended among others the need for the government to ensure adequate power supply in order to reduce the over reliance of economics sectors on gasoline as a prime source of power.

Three varieties of sorghum grains were germinated before fermentation to Ogi. The protein and ash contents of Sorghum vulgare, Sorghum guineensis and Sorghum bicolor increased by 7.20 and 40.20%; 5.44 and 29.20%; and 4.00 and 42.18% respectively. Fermentation of the germinated grains however caused decreases in the protein, ash, fibre and fat contents. Supplementation of oven-dried (60%) powder with treated 30% (w/w) soyabeans flour yielded products of higher protein contents which ranges from 284% for Ogi made from S. vulgare, 270% for Ogi made from S. guineensis and 271% for Ogi made from S. bicolor. Similarly, supplementation of Ogi with 30% (w/w) soya-flour generally resulted in increase in fat contents (approx. 130%), ash (approx. 54.9%) and fibre (approx. 217%). A panel of evaluators showed greatest preference for soya-supplemented Ogi porridge made from S. vulgare, while soya-supplemented Ogi porridge from S. guineensis was the least acceptable. The soya-supplemented Ogi flour (moisture content 10%) kept well and retained their original flow- properties after twenty-one days of storage. © 2010 Academic Journals.

The pressure dependence of the bond length and energy gap in chalcopyrite CuInS2 between 0 and 40 GPa has been investigated using pseudopotentials plane-wave method within the generalized gradient approximation for the exchange-correlation potential. We found that the bond length decreases as the pressure increases. Also, the energy gap of CuInS2 expands as the pressure increases with a rate of 10.693 meV/GPa. The linear pressure coefficient calculated is approximately half the reported experimental value of 23 meV/GPA. Our calculated bulk modulus of 68.7 GPa is in good agreement with the available experimental and theoretical values. The present calculations show that the d-electrons of Cu ions are one of the important factors that dominate the contributions to the I-VI bonds and the energy gap in CuInS2. © 2016 Elsevier Masson SAS.

In this work we carried out a review of models for evaluating the performance of distributed software system architecture (DSSA) and Information System (IS) success evaluation models with a view to establishing the utilization of organizational variables in the evaluation of DSSA performance. The findings from the review show that the existing DSSA performance evaluation models are machine-centric and existing IS success measurement models do not map organizational variables with DSSA components. In view of these, we developed a user-centric model for DSSA performance evaluation using organizational variables. Our model utilizes neuro-fuzzy logic in matching organizational/user variables with DSSA evaluation factors. © 2012 Elsevier Ltd. All rights reserved.

A survey was conducted on a piece of land at Idena village previously used as engineering site, but abandoned to fallow for the last 20 years at the outskirts of Ijebu-Ode Town in South-Western Nigeria, for medicinal plants diversity. The 2.4 ha fallow plot was subdivided into compartments and transect sampling technique was used for data collection. Data collected included; plant taxa, habit, species frequency, diversity and ethnobotanical values. Altogether 48 different medicinal plants represented by 25 different families were encountered, shrubs being the most prominent (18 species), trees (14), herbs (13), climbers (2) and 1 each for ferns and palms. Compartment 2 had the highest number (21 different medicinal plants) while compartment 6 had the least (4 medicinal plant species). The first three compartments accounted for over 50% of all the medicinal plants found. For taxonomic and frequency distribution, the family Euphorbiaceae had the highest (7), followed by Papilionaceae (4) and Rubiaceae (4), while seventeen other families had 1 species in each case. Relative density (RD) values ranged from 2.08 - 50% with the Euphorbiaceae accounting for the highest (50%), followed by Moraceae (22.9%), while seven other families had 2.08%. Computed Sørenson (Ss) coefficients of similarity between pair compartments ranged between 0.06 - 0.37 with highest value obtained between compartments 1 and 5 (0.37) and least between compartments 2 and 9 (0.06). Results also revealed that thirty three (33) different ailments could be managed with the different medicinal plants encountered. A large number of the medicinal plants encountered were indicated for the management of some prominent ailments including; diabetes, hypertension, fever/malaria and fertility thus suggesting high medicinal potential for the fallow plot. The need to develop sustainable conservation management plan for the fallow plot for its multiple roles is highlighted from this study. © 2010 Academic Journals.

Nine different media containing three different nitrogen sources, concentration of carbon source (cassava starch hydrolysate), and the pH were run in shake flasks to produce bioethanol using Saccharomyces cerevisiae. Analysis of variance of the results from the shake flask showed that there was no significant difference (P > 0.05) in the maximum concentration of ethanol (Pt) produced from the media. From the bioreactor studies, similar kinetic parameters, including Pt of 48.16 g/L with theoretical yield (Yetoh) of 92% and Pt of 47.13 g/L with Yetoh of 92%, were recorded from 100 g/L carbon source in the complex and minimal media, respectively. ©Taylor & Francis.

Several medicinal uses of the fluted pumpkin (Telfairia occidentalis) in traditional medicine have been documented. Although, many of these claims are yet to be validated by scientific researchers, a review of some investigated therapeutic activities of the plant are highlighted in this article. Experimental works done on Telfairia occidentalis especially in the field of Biochemistry were retrieved via Google search on the internet and studied carefully to identify any therapeutic activity reported on Telfairia occidentalis. It can be inferred that the ability of the plant to combat certain diseases may be due to its antioxidant and antimicrobial properties and its minerals (especially Iron), vitamins (especially vitamin A and C) and high protein contents. We therefore conclude that with further chemical manipulation and clinical investigations numerous drug designs could emerge from the plant. An effort to keep the plant protected and conserved is also advocated. © 2011 Academic Journals Inc.

Proximate and mineral analysis, carbohydrate (sugar) composition, functional properties and anti-nutritional factors of Tamarindus indica pulp and Zizyphus spina-christi fruits and seeds were determined with standard methods. Z. spina-christi seeds, T. indica pulp and Z. spina-christi fruit were rich in protein (24.07%, 7.64% and 8.23%, respectively). Crude fat content was 1.03% in T. indica pulp, 1.94% in Z. spina-christi fruit and 1.2% in Z. spina-christi seed, and carbohydrate contents of these samples were 56.00%, 58.02% and 35.25%, respectively. The values obtained for dextrose, fructose, maltose and other sugars showed that all samples had appreciable amount of sugar. Functional properties of Z. spina-christi fruit were relatively higher than in Z. spina-christi samples. These values are, however, comparable to earlier reports on Adenopus beriflorus Benth whole seed and lupin seed. Anti-nutritional factors investigated showed that T. indica pulp and Z. spina-christi fruit and seed contained low amount of oxalate, tannic acid and phytin phosphorus. The phytic acid values were 5.74, 6.156 and 8.24 mg/100 g for T. indica pulp and Z spina-christi fruit and seed, respectively. These values are, however, higher than other anti-nutritional factors. Fe contents for Z. spina-christi seed, T. indica pulp and Z. spina- christi fruit were 58.53, 27.36 and 39.96 mg/100 g, respectively, and it is evident that the seed can be used as a blood builder. Heavy metals like Mn and Pb were found in trace amounts with the WHO standard acceptable levels, which made the seeds non-toxic. The reports showed that T. indica pulp and Z. spina-christi fruit and seed are good source of protein, mineral and energy foods.

The influence of third grade, partial slip and other thermophysical parameters on the steady flow, heat and mass transfer of viscoelastic third grade fluid past an infinite vertical insulated plate subject to suction across the boundary layer has been investigated. The space occupying the fluid is porous. The momentum equation is characterized by a highly nonlinear boundary value problem in which the order of the differential equation exceeds the number of available boundary conditions. An efficient numerical scheme of midpoint technique with Richardson's extrapolation is employed to solve the governing system of coupled nonlinear equations of momentum, energy and concentration. Numerical calculations were carried out for different values of various interesting non-dimensional quantities in the slip flow regime with heat and mass transfer and were shown with the aid of figures. The values of the wall shear stress, the local rate of heat and mass transfers were obtained and tabulated. The analysis shows that as the fluid becomes more shear thickening, the momentum boundary layer decreases but the thermal boundary layer increases; the magnetic field strength is found to decrease with an increasing temperature distribution when the porous plate is insulated. The consequences of increasing the permeability parameter and Schmidt number decrease both the momentum and concentration boundary layer thicknesses respectively whereas an increase in the thermal Grashof number gives rise to the thermal boundary layer thickness. © 2013 Elsevier Inc.

The susceptibility of stabilized soil (SS) masonry components to forces of degradation is significantly dependent on the choice of constituent materials, production techniques, mode of exposure, as well as the aggressiveness of the medium to which they are exposed. This paper examines the choice of mix design format for SS masonry materials contingent on their weatherability characteristics and analyzes the mechanisms that trigger potential weathering variations. Two reproducible model soils (sandy loam [SL] and silty-clay loam [SCL]) in the presence of a variety of stabilizers, pressed at 6 N=mm2 into blocks, applied two curing routines, and measured weight loss following two forms of water-based degradation were used in the study. The test program shows remarkable potential for erosion resistance of SL-cement and SCL-lime mixtures that reflect the inherent variability in the material composition, nature of soil-stabilizer composites, and technique of exposure. The relevance of the weatherability study in the use of SS-based materials in the humid tropics demonstrates innovative and improved use of materials through clearly defined performance indicators and offers capability for retention of desirable properties like restrained configuration and attractive appearance in the building envelope, which otherwise would have been compromised. © 2014 American Society of Civil Engineers.
