A Simple Technique for Sustaining Solar Energy Production in Active Convective Coastal Regions

The climatic factors in the coastal areas are cogent in planning a stable and functional solar farm. 3D simulations relating the surface temperature, sunshine hour, and solar irradiance were adopted to see the effect of minute changes of other meteorological parameters on solar irradiance. This enabled the day-to-day solar radiation monitoring with the primary objective to examine the best technique for maximum power generation via solar option in coastal locations. The month of January had the highest turbulent features, showing the influence of weather and the poorest solar radiance due to low sunshine hour. Twenty-year weather parameters in the research area were simulated to express the systematic influence of weather of PV performance. A theoretical solar farm was illustrated to generate stable power supply with emphasis on the longevity of the PV module proposed by introducing an electronic concentrator pillar (CP).The pictorial and operational model of the solar farm was adequately explaine

Ergo-effects of designed school furniture and sitting positions on students behaviour and Musculo-Skeletal Disorder in Nigerian tertiary institutions

Improper design of school furniture is one of the contributing factors to back pain among students as indicated in some studies. In the case of designing school furniture where sitting constitutes a considerable time in the school, seat becomes important for comfort. This study is carried out in three selected institutions in Nigeria to determine level of musculoskeletal disorder in students’ and the furniture that they use. 720 questionnaires with 240 students (120 boys and 120 girls) drawn from each participating institutions were administered and 675 responses were received. The results show that the number of students having MSD, accounted for 93.75%. However, the distributions of pain in the body parts in each school were different. The musculoskeletal pain, mostly concentrated on neck, right shoulders right elbow right wrist right hand, upper back and lower back. The result also reveals that most of the students are sitting on chairs with seat that are too high and too deep or too shallow and of tables that are too high. However, it is recommended that further study on effect of designed school furniture and sitting position in larger sample of students’ representative in Nigeria tertiary institutions should be carried out in order to reduce the effect of body pains

Enhanced proactive planning approach: a crucial to an improved workers’ safety in Western Nigeria small scale industry

This study evaluated managements’ proactive planning approach (PPA) to enhance safety among workers in South-western Nigeria small scale industry (SSI). The main objective was to rate the managements’ efforts at eliminating risk among their employees. By worker participatory and psychological survey approach, three tools were used; workplace observation (visual), management safety culture (questionnaire) and managers interviews (oral). The survey included 200 workers, 120 supervisors and 80 managers, in 82 SSI. Four steps to a safety proactive action plans (PAP), (looking for clues, prioritization of identified potential hazard, making improvements to eliminate the risk and follow up), were rated by employees on a scale from 0 to 5. Paired t-test was used to appraise the significant difference between the managers’ mean scores rated by the supervisors and other workers. 77.1% of workers and 64.2% supervisors rated their managers as either “not done at all” or “poorly done”. Workers’ scores for managers PPA had statistically significantly lower ratings (mean = 1.09, SEM = 0.22) compared to that of the supervisors rating (mean = 1.55, SEM = 0.32), with t (14) = −1.185, p = 0.784. There is a closed poor performance perception gaps, of managers’ PPA, of the two groups of employees. It can be concluded that safety is not emphasized, by managers of SSI, as overriding priority and this may have contributed to high reported injuries among their workforce. Courses to enhance managements’ understanding for inclusion of safety among the leading priorities becomes necessary. This will reduce work-related risks and promotes occupational safety and health among the group of workers

How Reliable is the Cuprates System to Recent Technology?

The emergence of cuprates as a high Tc superconductor gave high hopes in the discovery of a room temperature superconductor. It is almost three decades and the highest critical temperature attained on the cuprates is about 135K. A brief overview was conducted on the progress made so far on the cuprates. A mathematical approach was used to design a formula which could determine the experimental results of critical temperature of versed cuprates superconductors. The result of our findings shows that the possibility of attaining the experimental room temperature cuprates superconductor seems very narrow. The study recommended an elaborate approach on the hybridization of cuprates for future research. Hence, there is possibility of having cuprates with wide engineering applicatio

Effectiveness of Solutions on Soilless Production of Lettuce Grown in Makurdi and Plateau, Nigeria

The experiment aimed to investigate the effectiveness of solutions on the growth and yield of lettuce grown in Makurdi and Plateau, Nigeria. The experiment is laid in a randomized complete block design with three replications. The treatments used are organic nutrient source, inorganic nutrients source and control, a varieties used where (Loose-leaf and Butter-head). During the investigation, some physiological variables, such as growth, plant height and the number of leaves, leaves diameter were measured. Other characteristics like dry weight, plant girth weight, root length, fresh weight and overall yield were also recorded. The results of the investigation revealed that lettuce generally responded to nutrient solution. All the parameter studies have significantly (P ≤ 0.05) responded to the nutrient solutions with inorganic nutrients solutions recorded higher in both growth and yield-related character such, as plant height (10.00cm), the number of leaves(20.05), dry weight (10.17g), girth weight (48.22g) and yield (30.10kg/ha). On varieties Loose-leaf out performed Butter-head in both growth, yield and yield related characters such as plant height (9.45cm), the number of leaves (20.20), dry weight (10.92g), girth weight (32.27g), root weight (18.27g), fresh weight (42.27g) and yield (14.92kg/ha) and Jos location was  superior in both growth and yield related characters. Based on the results obtained it can be suggested that lettuce farmers use inorganic nutrient solution which is better in both growth and yield characteristics leading to optimum yield in lettuce cultivation in the study areas

Taking the First Step towards Entrenching Mental Health in the Workplace: Insights from a Pilot Study Among HR Personnel in Nigeria

BACKGROUND: The continued relevance of optimal employee mental  health to sustainable human capital development in the workplace  underscores the need to start harnessing all resources that can be  mobilized to promote the entrenchment of workplace mental health. The strategic place of workplace Human Resource (HR) units in formulating and implementing workplace welfare schemes makes them potential partners. To actualize this, it is important to initially assess the preparedness of HR personnel for, and the possible barriers to entrenching mental health in the workplace. To suggest the initial course of action and to serve as a  template for a robust large-scale study, we conduct a pilot assessment of the experience with, attitudes towards, and level of prioritization of mental health in the workplace among a cohort of HR personnel in Nigeria.METHODS: Participants were recruited in the course of a seminar/workshop and questionnaires were developed by authors to assess variables of interest. Attitudes were examined using an adapted form of the Link's Discrimination-Devaluation (LD-D) scale.RESULTS:A total of 90 human-resource personnel completed the  questionnaires. Only 16% of the participants reported having handled the case of an employee with a suspected mental health problem in the preceding 2 years. Attitudes toward employees and prospective employees with mental illness were largely poor. For instance, more than 70% werelikely to consider for employment someone with a pre-existing physical disability than for someone with a history of mental illness. In terms of workplace health promotion priorities, physical health seminars took wide precedence over mental health seminars.CONCLUSION: The preliminary findings of this pilot study justify a need to conduct a large scale study. Significant challenges encountered in the course of this pilot study were highlighted while insights were drawn for the conduct of the main study/project.KEY WORDS: mental health, occupational health, workplace, HR personnel, attitude

ANAEMIA AMONG UNDERGRADUATES IN ABEOKUTA, OGUN STATE

 This study was conducted at the University of Agriculture, Abeokuta. Respondents were two hundred         (200) female undergraduates who filled out their questionnaires properly and had their anthropometric         measurements and their matching blood samples taken. Haemoglobin concentration was determined        for each respondent using WHO standard and their nutritional status assessed using Body mass index              2         (wt/ht ).   Descriptive   statistics   was   used   to   analyze   data   from   the   questionnaires.   Results   from   this        study showed that more than half (59%) of the population were anaemic. Many (45%) of the students        were also underweight. It can be concluded that the low haemoglobin levels found among the students         may be as a result of low food consumption and the frequent consumption of tea.  Nutrition education         is recommended to improve nutritional status of the students&nbsp
