Sport Talent Identification and Development in Nigeria
Olufemi Adegbesan,Martin Mokgwathi,Comfort Mokgothu,Kayode Omolawon,Jonathan Ammah,Isiaka Oladipo 한국코칭능력개발원 2010 International Journal of Coaching Science Vol.4 No.2
Sport talent identification and development has become an interesting area of sport science research and the need to explore the basic fundamentals of this process necessitated the need for this preliminary investigation in Nigeria with the view to develop an ideal sport talent identification and development model that could be used for future recruitment and selection of young potencial athletes. Data was collected from 50 participants using a self-report instrument based on the talent identification and development characteristics and indicatiors. Results indicated that the physiological characteristic with the mean value (m = 15.26 ± sd = 8.44) was the most apparent considered variable used by the participants during the talent identification and development process when compared with other variables of motor skill, psychology, physiology and body morphology. Results on the indicators of sport talent identification and development revealed that majority of the participants, 27(54.0%) of coaches place emphases more on both the performance of basic motor skills and the combination of the anthropometrical, physical and physiological profiles of the young talented athletes during the talent identification and development process. Conclusively, this baseline information has given us insight to the future direction of this research which is the examination of these talent identification characteristics and basic indicators using descriptive, field and laboratory measures with an enlarged sample that will include sport scientists. This will enable us to analytically dissolve the potentials of the young athletes into a series of measurable and non-measurable components.
Giant Solitary Anterior Cervical Canal Neurofibroma: Case Report and Surgical Technique
Olufemi Emmanuel Idowu,Kazeem M. Atobatele,Sunday O. Soyemi 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.4
Giant solitary anterior cervical canal neurofibroma (GSACCN) is rarely reported in the literature. When the large lesion is ventrally located to the spinal cord, an anterolateral approach may not be ideal due to various technical challenges. In this report, we describe a case of intradural extramedullary GSACCN located at the cervical region extending from the axis to the sixth cervical vertebrae. Here we also describe a posterior technique successfully used to resect the tumour. Therefore, the posterior approach by en bloc decompressive laminectomy and laminoplasty might be used to adequately treat the lesion.
Petroleum sludge treatment and disposal: A review
Olufemi Adebayo Johnson,Augustine Chioma Affam 대한환경공학회 2019 Environmental Engineering Research Vol.24 No.2
Petroleum industry produces one of the popular hazardous waste known as Petroleum Sludge. The treatment and disposal of petroleum sludge has created a major challenge in recent years. This review provides insights into various approaches involved in the treatment, and disposal of petroleum sludge. Various methods used in the treatment and disposal of petroleum sludge such as incineration, stabilization/solidification, oxidation, and bio-degradation are explained fully and other techniques utilized in oil recovery from petroleum sludge such as solvent extraction, centrifugation, surfactant EOR, freeze/thaw, pyrolysis, microwave irradiation, electro-kinetic method, ultrasonic irradiation and froth flotation were discussed. The pros and cons of these methods were critically considered and a recommendation for economically useful alternatives to disposal of this unfriendly material was presented.
Limit load equations for partially restrained RC slabs
Olufemi, O.O.,Cheung, K.L.,Hossain, K.M.A. Techno-Press 2005 Structural Engineering and Mechanics, An Int'l Jou Vol.19 No.1
The expertise required in the judicious use of nonlinear finite element (FE) packages for design-assistance purposes is not widely available to the average engineer, whose sole aim may be to obtain an estimate for a single design parameter, such as the limit load capacity of a structure. Such a parameter may be required for the design of a proposed reinforced concrete (RC) floor slab or bridge deck with a given set of geometrical and material details. This paper outlines a procedure for developing design-assistance equations for carrying out such predictions for partially restrained RC slabs under uniformly distributed loading condition, based on a database of FE results previously generated from a large number of 'numerical model' slabs. The developed equations have been used for predicting the peak loads of a number of experimental RC slabs having varying degrees of edge restraints; with results showing a reasonable degree of accuracy and low level of scatter. The simplicity of the equations makes them attractive and their successful use in the field of application reported in this paper suggest that the outlined procedure may also be extended to other classes of concrete structures.

Effects of additives on phase development and physico-mechanical properties of mullite-carbon was investigated. Powderedclay, kaolinite and graphite of predetermined compositions were blended with additives using ball mill for 3 hrs at 60 rev/min. Samples were produced by uniaxial compression and sintered between 1400 oC and 1600 oC for one hr. They werecharacterized for various properties, developed phases and microstructural features. It was observed that the properties andphase developments in the samples were influenced by the additives. 10 wt % SiC served as nucleating point for SiC around1400 oC. 10 wt % TiO2 lead to development of 2.5 wt % TiC at 1500 oC which increased to 6.8 wt % at 1600 oC. Ifon clay inthe sample leads to development of anorthite and microcline in the samples. 10 wt % TiO2 is effective as anti-oxidant forgraphite up to 1500 oC. Base on strength and absorbed energy, sample C (with 10 wt % TiO2) sintered at 1500 oC is consideredto be optimum.
