    The purpose of safety designing is generally not on cost, but rather on saving life and nature, and consequently bargains just with specific risky system failure modes. High reliability levels are the consequence of good designing, scrupulousness and dependably never the aftereffect of re-dynamic failure management. Failure mode and effect analysis (FMEA) is a helpful technique analyzing engineering system reliability. The study focused on the use of FMEA technique to analyze the reliability of engineering equipment or components in selected areas such as: Wind Turbine component, Manufacturing Industries, Medical field and in evaluating the performances of Robots in different fields. The study showed the importance of FMEA as used widely in analyzing engineering equipment with regards to reliability

    BACKGROUND: Secondary urethral stone although rare, commonly arises from the kidneys, bladder or are seen in patients with urethral stricture. These stones are either found in the posterior or anterior urethra and do result in acute urinary retention. We report urethral obstruction from dislodged bladder diverticulum stones. This to our knowledge is the first report from Nigeria and in English literature. CASE PRESENTATION: A 69 year old, male, Nigerian with clinical and radiological features of acute urinary retention, benign prostate enlargement and bladder diverticulum. He had a transurethral resection of the prostate (TURP) and was lost to follow up. He re-presented with retained urethral catheter of 4months duration. The catheter was removed but attempt at re-passing the catheter failed and a suprapubic cystostomy was performed. Clinical examination and plain radiograph of the penis confirmed anterior and posterior urethral stones. He had meatotomy and antegrade manual stone extraction with no urethra injury. CONCLUSIONS: Urethral obstruction can result from inadequate treatment of patient with benign prostate enlargement and bladder diverticulum stones. Surgeons in resource limited environment should be conversant with transurethral resection of the prostate and cystolithotripsy or open prostatectomy and diverticulectomy

    A journal article on the importance of girl-child education in the national development of Nigeria.The importance of girl-child education to the development of any nation cannot he overemphasised. There is a saying that "if we educate a boy, we educate one person, hut if we educate a girl, we educate a family and a nation". In many parts of the Africa, particularly in Nigeria, the girl-child face significant obstacles in accessing proper education, there is a serious gap between the boy-child education and that of girl-child due to inherent societal values placed on the boy-child over the girl-child. The girl-child has her destiny sealed by both tradition and culture on account of biological sex. There is also a seeming absence of policies that are specifically geared to attending to gender issues with obvious room for gender gap. It is on the basis of this that this paper examined issues in girl-child education in Nigeria and its implications on the development of the country. Peculiar issues such as access to education, school retention and drop out, equity as well as quality of education were closely examined vis-a-vis the implication on national development. The paper also proffered solutions to eradicating the problems facing girl-child education in Nigeria in order to achieve meaningful development. The paper concluded that education is the right of every girl-child, a key to transforming her life and making her a responsible member of the society. Therefore, the government should not only provide adequate policies to meet this yearning need, but also ensure that these policies are fully implemented

    In recent times the problem of environmental degradation of urban areas in Nigeria has reached an unprecedented proportion This phenomenon which is prevalent in both residential and industrial areas is caused by increased population growth unsustainable use of resources rapid industrialization unemployment income inadequacies as well as inefficient or non-existing waste management strategies This study examines the contributions of poverty as a reflection of income inadequacies and disparity to the availability of waste disposal facilities and its role in environmental degradation in Calabar urban area The research objectives are achieved though the identification of the disparity in household income distribution An assessment of the quality and quantity of waste disposal facilities available to housing units is made using primary and secondary data The findings reveal a wide pattern of disparity in household income and waste disposal facilities It is observed that the high density residential areas of Calabar South Local Government are not well served in waste management facilities resulting in environment degradation The medium and low density residential areas within the municipality are better served resulting in proper waste management The opinion of residents within the urban area is that government should be solely responsible for waste managemen

    Assessment of faecal contamination in selected concrete and earthen ponds stocked with African catfish, Clarias gariepinus

    Background: Microorganisms constitute significant fraction of the aquatic ecosystem and have been reported to be the cause of emerging novel infectious diseases in aquacultural practices. The prevalence of infectious diseases has been observed to depend on the interaction between fish pathogens and the aquatic environment. This study was conducted to assess the levels of faecal pollution markers in catfish (Clarias gariepinus) and their growing waters in selected earthen and concrete ponds in the teaching and research fish farm of the Federal University of Technology, Akure (FUTA), Nigeria in the dry (February-April) and wet seasons (May-July) of the year. Methodology: Two earthen and 2 concrete ponds were randomly selected as sampling sites due to their frequent usage. A total of 120 grabs of catfishes from the earthen (n=60) and concrete (n=60) ponds, and 84 pond water samples from earthen (n=42) and concrete (n=42) ponds, were randomly collected over a 6-month period of study. Enteric bacteria count in the water and catfish samples were determined using membrane filtration and pour plate methods respectively. The physiochemical characteristics of the water samples were determined using standard methods. The rate of bioaccumulation of faecal indicator bacteria was obtained by dividing the log count of each organism in the catfish by the corresponding log count in the growing waters. Results: Faecal coliforms count (log10 CFU/100ml) in the catfish from concrete and earthen ponds ranged from 1.41 to 2.28 and 1.3 to 2.47, and in the growing waters; 1.43 to 2.41 and 1.50 to 2.80 respectively. There was positive correlation of faecal coliforms with alkalinity of water samples from the earthen (r=0.61) and concrete ponds (r=0.62). Salmonella and faecal coliforms had the highest and least bioaccumulation in catfish raised in earthen pond while Salmonella and enterococci had the highest and least bioaccumulation in catfish raised in concrete pond respectively. Faecal coliforms and Escherichia coli had the highest and least counts in water samples from the earthen pond during the dry and wet months while Salmonella and E. coli had the highest and least counts in water samples from the concrete pond during the dry and wet months. Conclusion: High levels of bacterial faecal pollution markers in water samples and catfishes from the earthen and concrete ponds are reported in this study. Physicochemical characteristics and seasonality played major roles in the rate of bioaccumulation of the faecal pollution markers in catfishes raised in both earthen and concrete ponds

    PRESENTEEISM IN WORK PLACES AND ITS IMPLICATIONS ON EMPLOYEES’ HEALTH: EXPERIENCES OF BANKERS IN THE NIGERIAN BANKING SECTOR

    Presenteeism occurs when employees in an organization come to work even though they are ill. Usually such illness justifies an absence from work and as such, employees tend to carry out their roles under sub-optimal conditions.  This study examines the factors blameable for presenteeism among bankers in the Nigerian banking sector. The cross-sectional study was conducted in Ilorin, the capital of Kwara State in North central Nigeria. A total of 248 participants selected through multi-stage sampling method from eight commercial banks, was included in the study while primary data was collated through self-administered questionnaire administration.  Of those that participated in the study, (39.1%) fall within the age category of 18-30 years of age while (44.2%) fall in grade level of associate and support staff. Further result also acknowledged that (43.5%) of the participants were present at work when they were ill out of which, (34.8%) was due to enormous work load (28.0%) was due to participants’ passion for work (19.6%) was as a result of work pressure while, (17.3%) was due to the mild nature of participants’ illness. The study strongly recommends that government and other policy makers in Nigeria should legislate laws protecting bankers from coming to work when they are ill having been examined so by qualified physician.Keywords: Presenteeism, Employees, Work Load, Work Pressure, Bankers, Job Demands, Sector, DepositTarge
