Self-reported sleep parameters among secondary school teenagers in middle-belt Nigeria

Background: Available evidences seem to suggest increasing trend in sleep deficit among teenagers worldwide, and there is limited information on this among Nigerian teenagers. This study was carried out to determine the basic sleep schedule and sleep duration among schooling teenagers in Ilorin, Nigeria.Methods: This is a descriptive cross‑sectional study conducted among 20 selected public secondary schools in Ilorin, Nigeria. A multistage sampling technique was used to randomly select participating schools.Result: A total of 1033 students participated in the study; of these 47.3% were males and 51.7% females. Students mean age (standard deviation) was 15.3 ± 1.6 years with a range of 12–19 years. Majority (76.2%) of participants co‑share bed with at least one person and some (23.8%) slept alone in bed. The three leading reasons given for going to bed were: Tiredness ‑ 31.1%, completion of house assignment ‑ 20.5%, and parental directive ‑ 12.4%. 10% of teenagers do make regular phone calls at night and 5.5% surf internet and use computers at night. Regular habits of daytime sleepiness were reported by 8.2% of study participants. Students’ mean sleep duration during school days was 9.33 ± 2.29 h compared to 10.09 ± 1.32 h at weekend (P < 0.05). The duration of night time sleep was adequate (>9 h) in 41% of students; borderline (8–9 h) in 44.3% while 13.3% of the students had insufficient nighttime sleep duration (<8 h) P < 0.05.Conclusion: A substantial number of students had borderline nighttime sleep duration and so had potentials to transit into the problematic insufficient range. To prevent this, there is a need to educate schooling teenagers on the dangers associated with prolonged sleep insufficiency.Key words: Bedtime, schooling, sleep duration, teenagers, wake‑up‑tim

Rubber Impact on 3D Textile Composites

A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite. Yarn decohesions, matrix cracks and yarn ruptures have been identified as the major damage mechanisms under impact load. An increase in the number of 3D warp yarns is proposed to improve the impact damage resistance. The characteristic of a rubber impact is the high amount of elastic energy stored in the impactor during impact, which was more than 90% of the initial kinetic energy. This large geometrical deformation of the rubber during impact leads to a less localised loading of the target structure and poses great challenges for the numerical modelling. A hyperelastic Mooney-Rivlin constitutive law was used in Abaqus/Explicit based on a step-by-step validation with static rubber compression tests and low velocity impact tests on aluminium plates. Simulation models of the textile weave were developed on the meso- and macro-scale. The final correlation between impact simulation results on 3D textile-reinforced composite plates and impact test data was promising, highlighting the potential of such numerical simulation tools

Feasibility of a nurse-led home-based follow-up hypertensive care: A randomized control study in a North Central State of Nigeria

This article reported the development of a nurse-led, home-based follow-up care (HBFC) for hypertensive patients in Ilorin, Nigeria and assessed its feasibility. A Randomized Controlled Trial (RCT) was carried out in a tertiary hospital in Ilorin, Nigeria. For this study, 229 patients were recruited and openly randomized into patients that were followed up at home for 12 months (intervention) and those that were allowed to continue with the usual follow-up care (control) in the hospital using the usual routine hospital visit. The study presented the feasibility assessment of HBFC using three cardinal criteria; evidence of implementation, acceptability and practicability. There were retention rates of 83.9% and 83.3% for the intervention and study groups respectively. While no patients discontinued from among the patients in the intervention group, 13 patients discontinued in the control group. We concluded that it is feasible to conduct a home-based care for hypertension patients in a low resource setting like Nigeria.Key words: Feasibility, Home-based, Nurse-led, hypertension, Nigeri

The Politics of Intergovernmental Relations: Assessing the Many Phases and Challenges of Nigeria’s Judicial System

The judiciary is an important organ of government as it functions as a counterbalancing institution in states. Notwithstanding the nature of the political system in place, either democratic or nondemocratic, the judiciary plays the essential role of interpreting the extant laws and adjudicating between competing interests whether domiciled in individuals, groups, institutions of government or the various arms of government. The stabilising role of the judiciary in modern governance is exemplified by its ingrained function of checking the excesses of individuals, groups and government institutions through the application of state laws. Since Nigeria’s independence, its judiciary has been discharging its constitutional responsibilities. The journey of the Nigerian judiciary has been quite explosive, considering that it traversed both the jackboot of military authoritarianism and democratic governance in diverse forms, with each presenting its own peculiar bouquet of challenges. This chapter examines the various phases and attendant challenges that the Nigerian judiciary has passed through. It chronicles its many challenges and triumphs as well as low points. In sum, the Nigerian judiciary has acquitted itself admirably in dealing with such challenges as judicial independence, judicial accountability and crisis of condence occasioned by judicial recklessness and corruption. However, Nigeria’s judicial system still has room for further improvement in order to continue to command the respect of the citizens and thus, deserve such epithets as “the last hope of the common man”, “the bulwark of the people’s liberty”, “the defender of the rights of the people” and “the bastion of constitutional democracy,” among others, which demonstrate public acceptance and confidence

Preliminary evaluation of some aspects of the ecology (growth pattern, condition factor and reproductive biology) of African pike, Hepsetus odoe (Bloch 1794), in Lake Eleiyele, Ibadan, Nigeria

Abstract A preliminary investigation of length-weight relationship, condition factor and reproductive ecology of African pike fish, Hepsetus odoe, was conducted between June to August 2010 in Lake Eleiyele. A total of 90 samples of the fish species were caught by fishermen using gill nets. The results obtained showed that fish species had isometric growth pattern (contrary to negative allometry expected) with the growth exponent, b value of 2.64, that is not statistically different from 3 and with high statistical power of 0.866 when tested. The mean condition factor, K, was found to be 2.6, indicating that the fish species were in good condition in the study area. For reproductive biology, mean fecundity and gonadosomatic index were found to be 1349 eggs and 3.53% respectively. This study was necessary to fill the knowledge gap and provide information for management and conservation of the investigated species in the lake system. This study recommended that further research needs to be conducted because the sampling was carried out in the rainy season period and within a quarter of a year
