Edo Journal of Counselling , 2009,
Abstract: The study examined the influence of Age, Gender and Religion on eating habit of youth. It made use of simple random technique in selecting 400 youths within Ikenne local government of Ogun State, Nigeria. The age range of the respondents was between 15 years and 40 years with the mean age of 25.2 and standard deviation of 3.291. The ex-post facto research design was employed. A 20 item questions by Snell &Johnson (1997) named psychology of eating questionnaire (PEQ) was adopted with four subscales and used in generating data for the study. Data analysis involved the use of analysis of variance, and independent t-test. The results indicated that the three variables age, gender and religion taken together accounted for 30.2% of the variance in eating habit pattern and were found to the significant with {F3.397} = 5.214 . On the basis of this finding, it is then suggested that: Eating habit is affected by gender and age, nutritionist, social workers and those concerned with health should create more awareness on the poor eating habit as regards to healthy living.

M.O. Adeoye, O.O. Adewoye
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2006, DOI: 10.4236/jmmce.2006.51004
Abstract: Nanoindentation tests were performed on the basal (0001) and prismatic (10ī0) surfaces of tourmaline crystals. These results were used along with Vickers microhardness tests to investigate the hardness of the material on these surfaces at different load regimes. It was found that the (0001) surface indicated a higher hardness at ultra-low loads while (10ī0) becomes the harder plane at higher loads. Evidence of plastic deformation at room temperature in the otherwise very brittle (ceramic) material was also established, and the elastic modulus was determined.

M.O. Adeoye, O.O. Adewoye
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2004, DOI: 10.4236/jmmce.2004.32011
Abstract: Tourmaline is a ring silicate material with a hexagonal crystal structure. Tourmaline crystal is made use of as an electronic component, e.g, as a transducer, mainly because of the anisotropy it exhibits in its properties. Microindentation technique was employed in the research reported in this paper, using a Knoop indenter, to investigate the anisotropy in the hardness of the tourmaline crystal on its two major crystallographic planes: (0001) and {10 1 0}. The material was found to exhibit hardness anisotropy in conformity with its rotary symmetry elements. The material was identified and analysed using various x-ray techniques, and was found to contain some impurities as expected of natural crystals. Tourmaline was found to have a Si/Al ratio of 1.4. The orientations of the crystal samples were determined by obtaining and indexing the Laue x-ray back-reflection patterns of the crystal samples.

Research Journal of Applied Sciences , 2012,
Abstract: The complexes of Mn (II) aminobenzoates of the form [Mn(ABzt)2X2], {Abzt = o-NH2C6H4COO- X = C6H5NH2, C6H5NHCH3, C6H5N(CH3)2 C6H5N and p-NH2C5H4N} have been synthesized and characterized by microanalysis room temperature magnetic susceptibility measurements infrared and electronic reflectance spectral studies. In the complexes studied, some weak bands were observed in the region 26,000-29,000 and 18,000-19,000 cm 1. These have been assigned to the 6A1g(G) 4T2g(G)and 6A1g(G) 4T1g(G) transitions, respectively. This pair is highly indicative of an octahedral geometry.

Journal of Geography and Geology , 2012, DOI: 10.5539/jgg.v4n4p40
Abstract: Land use/land cover information is essential for a number of planning and management activities. The general patterns of land use/cover as they were recorded in remotely sensed data were discussed in this study. Multi-date satellite imageries (Landsat TM 1986, Landsat ETM+ 2001, Landsat ETM+ 2006 of 30m spatial resolution respectively and SPOT 5, 2007 of 10m spatial resolution) were obtained and used for the study. These images were enhanced, resampled, georeferenced and classified for the assessment of spatio-temporal pattern of land use/cover change in the study area. The study also utilized topographical map of the study area, derived from sheet number 247 of 1963, scale 1:50,000 to identify features, which were used as ground control point for image geo-referencing. ILWIS 3.2 Academic software was used to process the image data. The result of ground truthing was combined with visual image interpretation as training sites for supervised classification. Six different land uses/covers were identified and used to classify the image data. The results showed that the natural environments (vegetation, wetland resources, water bodies and mountainous terrain) were being threatened, as they reduced continually in the areal extent over time and space while the social environment (built up area) expanded tremendously. The study discovered that urbanization processes majorly responsible for land use/cover change in Lokoja. In conclusion, the study advanced our frontier of knowledge on land use/cover study by providing information on the status of natural and social environment in Lokoja, a confluence town, between 1986 and 2007 using remotely sensed images and Geographic Information Systems (GIS) technology.

Abstract:

Two new tris-chelate-complexes have been synthesized and characterized with elemental and spectroscopic methods. IR and thermal studies correlate with the structures of the complex in the solid state. The structure of [Cu(en)(phen)2]\"\" was determined with X-ray data using single crystal X-ray diffractometer while the molecular structure of [Cu(en) (phen)2] 2Br - 2Phen·8H2O was deduced from the used characterization methods. [Cu(en)(phen)2\"\" crystallizes as orthorhombic with space group Pbcn. Both complexes have distorted octahedral geometry. Microbial activities of these complexes against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptoccocus pyogeneous, Candida albicans, and Aspergillus niger were also reported.

International Journal of Engineering and Technology , 2012,
Abstract: Assessing the concentration of potentially harmful heavy metals in road side soils in Lagos metropolis is imperative in order to evaluate the potential risks to people and the environment. This is due to rapid increase in the use of vehicles for day to day transportation coupled with lack of emission standards which has raised serious concern about vehicular pollution. This paper reports the results of the investigation of heavy metal concentration in road side soils of selected areas in Lagos metropolis as a result of vehicular pollution. Locations considered were motor parks, garages and roadsides in Alimosho-, Agege-, Ikeja-, and Oshodi/Isolo-LGA of Lagos State. Seven locations that spans across the four local governments were selected on the basis of their high concentration of vehicular traffic. Three sites with low traffic concentration were also selected outside the seven locations to act as control sites. Soil samples were collected at each location for a period of three months in the dry season. The concentrations of six heavy metals (manganese, nickel, lead, chromium, zinc, and iron) in the samples were determined with an atomic absorption spectrometer (AAS). All the monitored heavy metal pollutants where compared with European Union (EU) regulatory standard. Results show that the concentrations of heavy metals in the soil samples from the seven locations were within safe limits though higher than in the control sites. It is evident that as time goes on, these heavy metals may pose health hazards. The study reveals that vehicular-related pollution in Lagos metropolis is indeed significant with possible severe health consequences.

Abstract:
This work reports a procedure for the fabrication of a complex mould using the technique of electroforming. This was with a view to finding a cheaper and less labour-intensive mould production route practicable locally. A Plaster of Paris electroforming mandrel in the shape of a water bottle was produced and made electrically conducting with a layer of copper conducting paint. Considerations for electroform removal were made by applying a thin, chloroform-dissolvable epoxy layer beneath the conducting copper paint. Uniformity of deposition on the mandrel was accomplished with the construction of a special deposition bath with multiple copper anodes around its perimeter. The electroforming was done in the galvanostatic electro deposition mode for about 240 hrs in a 1 M Cu2SO4 bath with the deposition of elemental copper on the mandrel. Incidences of rising bath pH were mediated with concentrated H2SO4. A free-standing electroform representing the mould cavity was formed in the deposition. The product so formed was a reproduction of the net-shape of the mandrel exhibiting smooth surface finish. The electroforming was cast with an aluminum backing layer to complete its transformation into a split mould. The finished mould was comparable in appearance to the imported moulds in terms of appearance and reproduction of intricate surface patterns. The simplicity and low cost of this method significantly reduced the requirements for expensive instrumentation and highly skilled labour for mould production.

Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.43021
Abstract: The design of a feasible Combined Heat and Power plant for a small community is presented. Of the many alternatives solid-waste disposal methods available, incineration of solid waste is recommended due to its potential energy recovery of the heat released during solid waste incineration and recovery of valuable by-products that can either be reused, re- cycled or marketed, among other advantages. Hence, an attempt is made to use the heat energy released during incin- eration of solid waste to produce steam in a boiler, which in turn powers a turbine for eventual generation of electricity. The two processes involved in the generation of electricity for in-plant use or for a small community via a steam turbine-generator combination and a gas compressor-gas turbine-generator are presented. The analysis of the amount of energy produced from the solid waste energy-conversion system using an incinerator-boiler-steam turbine-electric generator combination with a capacity of 4.5 tons/day is also presented. The net electric power for a small community was found to be 148.24 kW with an overall efficiency of about 21% having taken cognisance of the process power needs and unaccounted process heat losses. Moreover, exergy analysis of the proposed CHP plant was carried out whereby the respective energy and exergy efficiencies of 83.2% and 62.1% were obtained.

Middle East African Journal of Ophthalmology , 2010,
Abstract: Background: Onchocerciasis (river blindness) is a major cause of bilateral blindness with devastating socioeconomic consequences. Since Nigeria is the most heavily onchocerciasis endemic country in the world, the information on people′s knowledge about this disease is significant. This could influence their response to current preventive measures of the African Programme for Onchocerciasis Control. Aim: This study was designed to estimate the level of knowledge and attitudes of rural/semi-urban communities in Ife North Local Government Area of Osun State toward onchocerciasis. Materials and Methods: Cluster random sampling was used to select 500 adults for the study. Semi-structured questionnaires were administered to subjects. Data on knowledge of the local name, cause, mode of transmission, manifestation, severity, treatment, and prevention of onchocerciasis were collected and analysed. Statistical analysis included frequency distribution of the responses and a Chi-square test for comparison of variables with the P value for statistical significance set at 0.05. Results: Onchocerciasis was well known by its local name among 458 (91.6%) of the respondents. Only seven (1.4%) knew that it affects both the eyes and skin. The cause was commonly attributed to impure blood by 114 (22.8%), whereas transmission was thought to be through fomites by 161 (32.2%). Only 12 (2.4%) respondents attributed the disease to blackfly bites. The level of education and the association of onchocerciasis with a river were significantly associated (P = 0.001). Subcutaneous nodules were felt to contain water (85.4%), baby worms (3.2%), and fat (0.6%). There was a negative attitude toward sufferers of the disease. Conclusion: Adequate information transfer in simple local dialect by trained personnel to the communities at risk of onchocerciasis is essential for better uptake of all aspects of the onchocerciasis control programme.
