Reliability Assessment of some Selected 11 kV Feeders within Ibadan Distribution Network

The energy satisfaction that consumers can obtain from the central grid solely depends on how reliable the feeder to which such customers are connected, simply because the reliability of both generation and transmission is not enough to guarantee adequate and secure energy delivery. It is on this premise that this paper employed load point reliability indices to assess selected feeders within the Ibadan electricity distribution network. The required data for this analysis was collected from the Ibadan Electricity Distribution Company, at Ring Road, Ibadan, the collected data captured the total number of faults, total fault duration, and total operating time from 2016 to 2019. The load point reliability indices used as performance metrics include Failure Rate (FR), Mean Time Between Failures (MTBF), Mean Time to Repair (MTTR), Availability Factor (AVF), and Maintainability (M). An adequate comparison of each of these indices on each feeder was made for the period of investigation. It was discovered that many of these feeders were not reliable. Therefore, the need to carry out extensive maintenance on these feeders is non-negotiable. Also, the result of this analysis will help the Distribution Company (DisCo) to make informed decisions that will accelerate the reliability of these 11kV feeders across the investigated region

Differential Psycho-Social Factors as Predictors of Female Academicsa Career Growth and Leadership Positions in Universities in South-West Nigeria

Recent studies affirm that academic women are a minority have slow career growth compared to their male colleagues and almost invisible in leadership positions therefore excluded from power structure These have been attributed to culture socialisation conditioning and self-perception of the women themselves However differential psycho-social factors predicting female academics career in Nigerian Universities are yet to be examined This study therefore affirmed the efficacy or otherwise of differential psycho-social predictors of female academics career growth and leadership positions in universities in South-West Nigeria This research adopted a descriptive survey research design of the ex-post facto type Multistage sampling involving purposive and stratified random techniques were used to select 587 respondents from six Universities in South-West Nigeria Five hundred and thirty eight Female Academics from Graduate Assistant to Professor three hundred male academics senior lecturers sixty members of appointment and promotion committee participated in the study Female Academics Psychological Questionnaire R 0 82 Social Factors Questionnaire R 0 87 Female Academics Career Growth Questionnaire R 0 79 and Female Academics Leadership Questionnaire r 0 84 were used for data collection Twelve research questions were answered Data were analysed using multiple regressio

Recommender system for modelling subject combination in Ugandan senior secondary schools

Subject combinations at A-level in Ugandan Senior Secondary Schools have made or marred the future career of many prospective students, many students have ended up doing courses they had not planned to do because they made wrong choices at their A-level. This recommender system offers the decision-making process for students based on their subject performance coupled with interest, passion, skills and talents to enable them make right choices. It is person-centred and there are three (3) main actors: the student (who are interested in making appropriate career choice), the documents (which contains available information about interest and passion, skills and talents and subject performances) and access metrics (which aids the student of A-level in extracting knowledge from available resources). A hybrid matrix factorization model using ANFIS and R were used to represents students and subjects as linear combinations derived from their characteristics and interactions, this is combined with rule-based model to offer a unified approach of presenting any student with a list of subjects that will lead to prospective career choices. This offer higher predictive accuracy in career choice matchmaking and overcoming challenges of parental influence, peer influence and others while expanding opportunities of career guidance in Uganda.

Nursing care practices to improve acute stroke care : a descriptive literature review

Acute stroke starts suddenly, but typically worsens rapidly. Therefore, it is considered as a devastating illness requiring emergent attention and care, considering its adverse effects of leading to a high degree of patients’ mortality and inadvertently physical incapacity. Therefore, the aim of this thesis is to find out nursing practices required for care of acute stroke, and furthermore, to discover recent research in tackling the risk factors and the role of nurses in the care of acute stroke patients. Furthermore, this study is carried out by reviewing literature in order to discover nursing practices in the care of patients with acute stroke, and to study how nursing care of acute stroke can be improved by the enhancement on the use of evidence with regards to the prevention of early complications. The prevention of complications within the first 24 - 48hrs decreases stroke-related mortality, therefore, using the electronic database searches of CINAHL, PubMed and SAGE and considering the inclusion and exclusion criteria. Furthermore, codes retrieved were recorded after which themes were being generated. Hence, the major themes formed were: Nurse led ward round, Goal setting and Nursing support which were further divided into sub-themes. Finally, It has been discovered that the management and care of stroke involves the carrying out of evidence-based approach which could therefore be implemented by professionals within the healthcare team, in order to emphasize the care in recognizing, response, and treatment are delivered in an inclusive approach, and as such, nurse-led ward round has proven to be a powerful tool to empowering nurses to make decisions within their professional capabilities, within which its contribution has had a significant impact on patient care and safety through early detection and prevention of stroke complications, in an acute setting

Couple asymmetries and its impact on modern contraceptive use among young (15-24) married women in Nigeria

A dissertation submitted in partial fulfillment of the requirement for the award of Master of Arts in Demography and Population Studies, University of the Witwatersrand, 2017BACKGROUND: Nigeria has a very low level of modern contraceptive use; with resultant effects of high fertility, and maternal and child mortality. It is Africa’s most populated country, and with a rapid growth rate. Modern methods of contraception is a crucial strategy to reduce the high fertility rate, halt population growth, lessen child mortality, and enhance maternal health. This study aims to assess partner’s economic and demographic asymmetries as barriers contributing to the uptake of modern contraceptives among young married and cohabiting women aged 15-24 years in Nigeria. METHOD: This study used data from the Nigerian Demographic and Health Survey 2013, with a sample of 4,981 young (15 – 24 years) married and cohabiting women. The Health Belief Model was used to explain partner’s socio-economic and demographic differences as barriers to the utilisation of modern contraceptives. Frequency distributions and binomial logistic regression were carried out using STATA v12 to answer the research questions. RESULTS: Only 6% of young married and cohabiting women use modern contraceptives. In the unadjusted analyses, women who were in less homogamous unions were less likely to practise modern method contraception. Respondents younger than their partners by 6-10 years and respondents younger by 11 or more years were less likely to use modern contraceptives (UOR= 0.357, CI 0.135-0.943; UOR= 0.223, CI 0.084-0.595). Respondents whose partners want more children were less likely to use modern contraceptives while respondents whose partners want fewer number of children compared to them were more likely to use modern contraceptives (UOR= 0.325, CI 0.240-0.439; UOR= 1.812 CI 1.1082.963 respectively). However, these associations were no longer significant after adjusting for women’s age, highest level of education, place of residence, religion, and region of residence and other differences. CONCLUSION: This study concluded that socio-economic and demographic differences between married partners are not associated with young women's contraceptive use in Nigeria, after adjusting for women’s characteristics. Further studies, especially qualitative studies, are needed to understand this finding. Keywords: Modern contraceptives, young married women, partner asymmetries, Health Belief Model, NigeriaGR201
