An Assessment of Nigerian Musical Vidoes’ Representation of Nigerian Culture
This study investigates Nigerian music video representation of Nigerian culture. Experiment research design was conducted with 25 control and 25 experiment groups. The experiment group was exposed to ten selected music video that were considered as running contrary to Nigerian culture. After which both groups were asked the same questions. The result showed no significant statistical difference in the scores of control group (M=1.5600, SD=..50662) and experiment group (M=,1.7600, SD=.43589) ( p>0.05) as both groups reported that Nigerian music video represent Nigeria culture in bad light. The result also showed no significant statistical difference in the scores of control group (M=1.2000SD=..40825) and experiment group (M=,1.2800SD=.45826), (p >0.05).Both groups reported that Nigerian music videos corrupt public morals. Findings further showed no significant statistical difference in the scores of control group (M=1.5200,SD=.50990) and experiment group (M=,1.8400,SD=.37417), t (48) ( p> 0.05). Both groups reported that Nigerian music videos do not promote Nigerian culture .Based on the result of this study, the researcher recommends among others that the Nigerian Film and Video Censorship Board should step up efforts in monitoring the quality of music video that are released into the Nigerian market. Keywords: culture, music, Nigeria, representation and vide

Investigation of the Effects of Flowline Sizes, Flow Rates, Insulation Material, Type and Configuration on Flow Assurance of Waxy Crude
The recovery of hydrocarbons has gone into deep and ultra-deep waters. Typically, operations from such an environment make the system susceptible to flow assurance challenges. Operations with long subsea flowlines need special attention with respect to flow assurance problems, especially with respect to wax deposition and risk of hydrate formation. As a result, during such operations, it becomes very crucial to evaluate the flowline sizes, flow rates and subsea flowline lengths to minimize flow assurance problems. For the wax deposition control, the operating temperature must be maintained above wax appearance temperature (WAT) by either insulation or electrical heating depending on the cost and energy efficiency factors. In this study, several multiphase simulations were carried out using PIPESIM software to investigate the effects of flowline sizes, flow rates, insulation material, type and configuration on flow assurance of waxy crude over 10.2 km between the wellhead and the first stage separator on the platform. Considering the implications of these factors for flow assurance. The data and results obtained from this study suggest that line size of 0.29 m, the flow rate of 3280 m3/d, poly-urethane foam, and pipe-in-pipe insulation type are favourable to flow assurance of waxy crude with respect to maintaining the temperature of the fluids above the wax appearance temperature of 26 oC; and also to deliver the fluids to the platform at the recommended pressure of over 11 bar.

Stroke admissions in Kubwa General Hospital: A 30-month review
>Background: Stroke is a common neurological disorder that contributes significantly to the morbidity and mortality of medical admissions.Objectives: To review the types, risk factors, hemispheric involvement, and outcomes of admitted stroke patients in Kubwa General Hospital, Abuja, Nigeria.Subjects and Methods: We carried out a retrospective study of patients who had a clinical diagnosis of stroke in Kubwa General Hospital, Abuja, Nigeria, between January 2013 and June 2015.Results: A total of 60 patients who had stroke were admitted during this period, accounting for 4.25% of medical admissions. Men and women accounted for 68.3% and 31.7%, respectively, with a male-to-female ratio of 2:1. Their mean age was 54.9 ± 13.5 years while the median age was 52.5 years. The mean hospital stay for these patients was 8.4 ± 5.5 days. Ischemic stroke occurred more frequently (65%) compared with hemorrhagic stroke (35%). Hypertension (65%), alcohol (25%), previous stroke (18.3%), diabetes mellitus, and hypercholesterolemia (18.3%) were the common identifiable risk factors for stroke. Ten patients (16.7%) had two risk factors for stroke, whereas 8 patients (13.3%) had three risk factors for stroke. The mean systolic and diastolic blood pressures on admission were 171.5 ± 41.6 mmHg and 103.3 ± 24.0 mmHg, respectively. The left hemisphere (53.3%) was more often affected than the right hemisphere in these patients. Majority of the patients (48.3%) were discharged following improvement while the case fatality was 11.7%.Conclusion: Stroke is not uncommon as a cause of medical admission in Kubwa General Hospital. Ischemic stroke occurred more commonly and the left hemisphere was more often involved compared with the right hemisphere. Hypertension was the most common risk factor for stroke in these patients
Applying decision trial and evaluation laboratory as a decision tool for effective safety management system in aviation transport
In recent years, in the aviation industry, the weak engineering controls and lapses associated with safety management systems (SMSs) are responsible for the seemingly unprecedented disasters. A previous study has confirmed the difficulties experienced by safety managers with SMSs and the need to direct research to this area of investigation for more insights and progress in the evaluation and maintenance of SMSs in the aviation industry. The purpose of this work is to examine the application of Decision Trial and Evaluation Laboratory (DEMATEL) to the aviation industry in developing countries with illustration using the Nigerian aviation survey data for the validation of the method. The advantage of the procedure over other decision making methods is in its ability to apply feedback in its decision making. It also affords us the opportunity of breaking down the complex aviation SMS components and elements which are multi-variate in nature through the analysis of the contributions of the diverse system criteria from the perspective of cause and effects, which in turn yields easier and yet more effective aviation transportation accident pre-corrective actions. In this work, six revised components of an SMS were identified and DEMATEL was applied to obtain their direct and indirect impacts and influences on the overall SMS performance. Data collection was by the survey questionnaire, which served as the initial direct-relation matrix, coded in Matlab software for establishing the impact relation map (IRM). The IRM was then plotted in MS Excel spread-sheet software. From our results, safety structure and regulation has the highest impact level on an SMS with a corresponding positive relation level value. In conclusion, the results agree with those of previous researchers that used grey relational analysis. Thus, DEMATEL serves as a great tool and resource for the safety manager
