Banana peels, a common fruit waste was adopted as a material precursor in this study to synthesize highly porous activated carbon from banana peels (ABP) which serves as an electrode material for a symmetric supercapacitor device. The activation was done using KOH pellets at different carbonization temperatures ranging from 750 C to 950 C. The ABP sample obtained from the 900 C carbonization temperature (ABP900) exhibited unique material properties such as hierarchical porous nano-architecture containing micropores, and mesopores with the highest specific surface area (1362 m 2 g À1). Electrochemical performance investigation in different neutral aqueous electrolytes showed that the best response was obtained in NaNO 3 for the ABP900 electrode. The symmetric device subsequently assembled using 1 M NaNO 3 operated in a potential window of 1.8 V, exhibited a specific capacitance of 165 F g À1 with a corresponding energy density of 18.6 W h kg À1 at 0.5 A g À1. A 100% capacitance retention and columbic efficiency were obtained after 10000 continuous charge-discharge cycles at 5 A g À1. Remarkably, after subjecting the symmetric device to a voltage holding test for 60 h, the specific capacitance was observed to increase from 165 F g À1 to 328 F g À1 with a corresponding increased energy density to about 36.9 W h kg À1 at 0.5 A g À1 , suggesting a 98% increase in device energy density from its initial value after voltage holding. Thus, the results reported showcase the ABP900 material as a potential nanostructured porous material useful in the design of high-performance electrodes for stable electrochemical capacitors.

Jaiyeola, T, Effiong G.  2018.  Basarab loop and its variance with inverse properties, 2018/12/01. 26:229-238. Abstract

A loop (Q, ·) is called a Basarab loop if the identities: (x · yxρ)(xz) = x · yz and (yx) · (xλz · x) = yz · x hold. It is a special type of a G-loop. It was shown that a Basarab loop (Q, ·) has the cross inverse property if and only if (Q, ·) is an abelian group or all left (right) translations of (Q, ·) are right (left) regular. In a Basarab loop, the following propertiesare equivalent: flexibility property, right inverse property, left inverse property, inverse property, right alternative property, left alternative property and alternative property. The following were
proved: a Basarab loop is a weak inverse property loop if it is flexible such that the middle inner mapping is contained in a permutation group; a Basarab loop is an automorphic inverse property
loop if a semi-commutative law is obeyed such that the middle inner mapping is contained in a permutation group; a Basarab loop is an anti-automorphic inverse property loop if every element
has a two-sided inverse such that the middle inner mapping is contained in a permutation group; a Basarab loop is a semi-automorphic inverse property loop if the Basarab loop is flexible, the
middle inner mapping is contained in a permutation group such that a semi-cross inverse property holds; a Basarab loop with the m-inverse property such that a permutation condition is true is
a cross inverse property loop if it is flexible. Necessary and sufficient conditions for a Basarab loop to be of exponent 2 or a centrum square were established.

PurposeBuilding information modeling (BIM) inclusion in education pedagogy is crucial in preparing skilled graduates for employment in the construction industry. Against this backdrop, studies on BIM education abound in architecture, engineering and construction (AEC) programmes in higher education institutions (HEIs). However, there are limited empirical studies on BIM potentials in the quantity surveying (QS) profession in HEIs, particularly in developing countries. The purpose of this study is to identify and assess the BIM drivers and benefits as important to the QS profession using an empirical approach.
Design/methodology/approach
A comprehensive literature review was conducted to identify the BIM drivers and benefits in relation to the QS profession, which was used to design a questionnaire. To capture a broad perception, a questionnaire survey was carried out which targeted the academia and final year undergraduate students from two selected universities offering QS honour degree programmes in Nigeria. Data collected were analysed using mean score, standard deviation and Mann–Whitney test.
Findings
The study identified 12 BIM drivers in relation to the QS profession and the analysis of the ranking revealed that almost all the identified BIM drivers are considered by respondents as important. The study further identified 14 BIM benefits and the analysis of the ranking indicated that all the identified BIM benefits are considered as important. The results of the Mann–Whitney test indicated a slight statistically significant difference, particularly in one of the selected universities on the ranking of the BIM drivers and benefits as important to the QS profession.
Practical implication
The findings of the study provide empirical evidence on the current perceptions of the drivers and benefits of BIM to QS academia and students as they explore the concept for the advancement of QS profession.
Originality/value
This study would provide practical insights to use BIM for QS practice. Also, this study would contribute to improving the QS graduates and professional quantity surveyors understanding of the BIM knowledge applicable to QS profession.

Ameye, S, Adeyemo A, Eziyi J, Amusa Y.  2018.  Clinical profile of otomycosis in a sub-saharan African tertiary health center, 2018/05/01. 10:52-55. Abstract

Aims: This study is aimed at determining the presentation, predispositions, types and treatment outcomes of patients diagnosed with otomycosis in our center. Materials and methods: We reviewed 83 cases of otomycosis who visited the otorhinolaryngology clinic of our center in the period of 5 years. Diagnosis of otomycosis was clinically based on presentation and findings on otoscopic appearance. Results: Records of 83 cases of otomycosis consisting of 40 males and 43 females were analysed. The mean age was 43.19 ± 20.74 years. Twenty-eight (33.7%) patients were asymptomatic with the otomycosis discovered following otoscopy during a clinic visit. Pruritus, ear ache and hearing loss were the commonest complaints among the symptomatic patients. Unilateral disease was seen in 57 (68.7%) of the patients and bilateral disease in 23 (27.7%) of the patients. The affected side was not stated in 3 (3.6%) of the patients. Examination findings revealed in most cases (78, 94.0%) reveal presence of fungal debris. The use of ototoptic medication was noted as the risk factor for more three-quarter of those with identifiable risk factor. Total fifty-one (61.4%) patients had complete resolution. Conclusion: We found otomycosis to be predominantly an adult disease and it is an incidental finding many case. The overall outcome is good regardless of the mode of treatment employed. Clinical significance: The limitation to due to non-available of a particular mode of treatment should not impair obtaining a good outcome when managing otomycosis. © 2018, Jaypee Brothers Medical Publishers (P) Ltd.

Eziyi, J, Oninla O, Salawu T.  2018.  Ear infections in primary school children of south western Nigeria, 2018/04/26. 4:608. Abstract

p class="abstract"> Background: Prevalence of ear infections in primary school children in Nigeria is scarcely documented and available studies are mostly hospital based. The aim of this Community based study is to define the point prevalence of ear infections among school children.Methods: Using a multi- staged stratified sampling technique, 630 pupils aged 6-12years, attending Government owed primary schools in two local government areas in the South Western Nigeria were recruited for the application of a structured questionnaire, single examination and classification using their socioeconomic index.
Results: Three hundred and seven (48.7%) were females and three hundred and twenty three (51.3%) were males. Chronic otitis media had the highest prevalence of 7.9%, followed by acute otitis media and otitis externa (3.2%) while otomycosis (1.6%) had the lowest. Majority of the infections were unilateral and more prevalent in the males. It was observed that all the ear infections were more prevalent in pupils from the low socioeconomic class although not statistically significant.
Conclusions: These results shows that ear infections is still common in our primary schools and that socioeconomic status and sex of the pupils did not significantly affect the occurrence of these ear infections. There is a need to incorporate health education programme in schools to prevent ear infections and the attendant disabilities.

Eziyi, J, Musa I, Dubem U, Mike I, Salawu T, Babtunde O.  2018.  Facial Nerve Palsy and Management: Our Experience, 2018/03/30. 6 Abstract

The Facial nerve is the most common cranial nerve to be paralysed due to the fact that it has a long intracranial route, related to the ear and parotid gland and thus susceptible to injuries and infections. This study aims to describe the epidemiology and management of facial nerve palsy. A retrospective cohort review of patients that presented to ORL-HNS Department of Obafemi Awolowo University Teaching Hospital Complex (OAUTHC), Nigeria from November 2008 to March 2015 was done. The age, sex, clinical presentations, duration of symptoms prior to presentation, aetiology/diagnosis, treatment and outcome were obtained. Twenty-six patients with age ranging from 1.7 to 83 years and a male: female ratio of 1.6:1 was analysed. Facial nerve palsy occurred more on the left (61.5%) and all unilateral. Otogenic aetiology accounted for 34.62% (9 Cases) followed by idiopathic (26.92%), 5 (19.23%) were due to Malignant parotid tumour, 3 (11.55%) due to temporal bone fracture, and a case (3.84%) due to iatrogenic trauma. The duration of facial nerve palsy before presentation ranged from 1 day to 1 year with a mean of 6.1months. All the patients had eye care, other modalities of treatment included one or a combination of antibiotics, steroids, physiotherapy, acyclovir and surgery. None had facial nerve decompression, repair or grafting done. Outcome was good in 4 cases (15.4%), satisfactory in 10 cases (38.5%) and unsatisfactory in 3 cases (11.5%), 9 cases (34.6%) were loss to follow up. Facial nerve from otogenic causes ranked highest in our environment. Late presentation and defaulting during treatment is still a challenge in our environment and affect the outcome of facial nerve palsy.Keywords: facial nerve palsy, ear infection, iatrogenic, trauma, Parotid tumours.

Objectives: To determine the cost burden of Neuroimaging and its contribution to direct total hospitalization costs (HCs) during one-time admission for first-ever stroke. Methods: The clinical characteristics, direct itemised costs and total HCs for 170 consecutive patients with first-ever stroke, admitted at our public tertiary health facility over a 15-month period were evaluated. Results: The records of 170 stroke subjects were reviewed. The median total HCs for one-time admission per stroke patient was $183.30 with a median daily cost of $15.86. Median cost of radiological investigations was the highest among the categorized hospital costs. Among the radiological investigations, neuroimaging accounted for at least 99% of cost to patients. Conclusion: The financial burden of radiological investigations, particularly neuroimaging, is high during one-time admission of patients with first-ever stroke in our environment.

The Lancet Global Health. 6(4) Abstract

Background: Sub-Saharan Africa has the highest incidence, prevalence, and fatality from stroke globally. Yet, only little information about context-specific risk factors for prioritising interventions to reduce the stroke burden in sub-Saharan Africa is available. We aimed to identify and characterise the effect of the top modifiable risk factors for stroke in sub-Saharan Africa. Methods: The Stroke Investigative Research and Educational Network (SIREN) study is a multicentre, case-control study done at 15 sites in Nigeria and Ghana. Cases were adults (aged ≥18 years) with stroke confirmed by CT or MRI. Controls were age-matched and gender-matched stroke-free adults (aged ≥18 years) recruited from the communities in catchment areas of cases. Comprehensive assessment for vascular, lifestyle, and psychosocial factors was done using standard instruments. We used conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% CIs. Findings: Between Aug 28, 2014, and June 15, 2017, we enrolled 2118 case-control pairs (1192 [56%] men) with mean ages of 59·0 years (SD 13·8) for cases and 57·8 years (13·7) for controls. 1430 (68%) had ischaemic stoke, 682 (32%) had haemorrhagic stroke, and six (<1%) had discrete ischaemic and haemorrhagic lesions. 98·2% (95% CI 97·2–99·0) of adjusted PAR of stroke was associated with 11 potentially modifiable risk factors with ORs and PARs in descending order of PAR of 19·36 (95% CI 12·11–30·93) and 90·8% (95% CI 87·9–93·7) for hypertension, 1·85 (1·44–2·38) and 35·8% (25·3–46·2) for dyslipidaemia, 1·59 (1·19–2·13) and 31·1% (13·3–48·9) for regular meat consumption, 1·48 (1·13–1·94) and 26·5% (12·9–40·2) for elevated waist-to-hip ratio, 2·58 (1·98–3·37) and 22·1% (17·8–26·4) for diabetes, 2·43 (1·81–3·26) and 18·2% (14·1–22·3) for low green leafy vegetable consumption, 1·89 (1·40–2·54) and 11·6% (6·6–16·7) for stress, 2·14 (1·34–3·43) and 5·3% (3·3–7·3) for added salt at the table, 1·65 (1·09–2·49) and 4·3% (0·6–7·9) for cardiac disease, 2·13 (1·12–4·05) and 2·4% (0·7–4·1) for physical inactivity, and 4·42 (1·75–11·16) and 2·3% (1·5–3·1) for current cigarette smoking. Ten of these factors were associated with ischaemic stroke and six with haemorrhagic stroke occurrence. Interpretation: Implementation of interventions targeting these leading risk factors at the population level should substantially curtail the burden of stroke among Africans.

PLoS ONE. 13(11) Abstract

Introduction Stroke is a prominent cause of death, disability, and dementia in sub-Saharan Africa (SSA). The Stroke Investigative Research and Education Network works collaboratively with stroke survivors and individuals serving as community controls to comprehensively characterize the genomic, sociocultural, economic and behavioral risk factors for stroke in SSA. Purpose In this paper, we aim to: i) explore the attitudes, beliefs, and practices related to stroke in Ghana and Nigeria using the process of qualitative description; and ii) propose actions for future research and community-based participation and education. Methods Stroke survivors, their caregivers, health care professionals, and community representatives and faith-based leaders participated in one of twenty-six focus groups, which qualitatively explored community beliefs, attitudes and practices related to stroke in Ghana and Nigeria. Arthur Kleinman’s Explanatory Model of Illness and the Social Ecological Model guided the questions and/or thematic analysis of the qualitative data. We hereby describe our focus group methods and analyses of qualitative data, as well as the findings and suggestions for improving stroke outcomes. Results and discussion The major findings illustrate the fears, causes, chief problems, treatment, and recommendations related to stroke through the views of the participants, as well as recommendations for working effectively with the SIREN communities. Findings are compared to SIREN quantitative data and other qualitative studies in Africa. As far as we are aware, this is the first paper to qualitatively explore and contrast community beliefs, attitudes, and practices among stroke survivors and their caregivers, community and faith-based leaders, and health professionals in multiple communities within Nigeria and Ghana.
