Poorly maintained living conditions and infrastructure are the banes of Nigerian prisons. The study investigated its environmental conditions and the prevalent diseases among inmates. The descriptive, cross-sectional study enrolled 420-inmates through a multistage sampling technique. Pre-tested instruments were administered and results presented with descriptive and logistic regression to identify predictors of toilet-cleaning and handwashing practices at P∝0.05. The mean(±SD) age and modal inmates/cell were 30±7.2 years and 36. Most inmates were males (97%), await-trial (79%) and lives in overcrowded cells (58%). Sixty-nine percent of free-cells has pour-flush toilets and 36% waits for 2–5 minutes before accessing toilets. Fifty-three percent of inmates clean latrines with water and soap, 71% burn solid waste while handwashing period-prevalence was 36%. Religion, toilet-cleaning, and education were predictors of handwashing while types of toilets and access predict toilet-cleaning behaviour. Malaria (81.1%) and scabies (7.3%) were endemic. The prison rehabilitation shall satisfy basic life needs and promote prisoners' health.

The existence and multiplication of open dumpsites (ODs) around residential settlements are associated with environmental health outcomes in urbanizing settlements of developing countries. The study assessed existing practice and perceived health hazards of residence around ODs in Nigerian heterogeneous urban settlements. The cross-sectional, mixed-method study administered a validated questionnaire on 195 respondents using a 4-stage sampling technique. Two focus group discussions (FGDs) were conducted and analysed by ATLAS.ti software. Continuous and categorical variables were respectively presented by means and proportions; associations among variables were determined by chi-square and logistic regression at P$\alpha$<0.05. Seventy-two per cent of the respondents disposed of solid waste in ODs, despite good knowledge (95%) and a positive attitude (85%) on perceived health-hazards. One-sixth (15%) of respondents were willing to pay for waste collection service and 50% considered burning as an alternative to open dumping. The most and least perceived health outcomes were malaria and breathing difficulties. Improved water sources and skin irritations were significant predictors of sound SWM practices.

BackgroundSurgical operation and anaesthesia induction are fearful events which may interfere with the smooth conduct of anaesthesia and postoperative recovery in children. Indeed, the fear of needles, syringes and unknown hospital environment often compound their anxiety. Various modalities such as use of clowns, music, low intensity light in the induction room, pharmacological agents and parental presence during induction of anaesthesia have been utilized with the aim of gaining the cooperation of the children during induction. However, their use has yielded conflicting results. This prospective study was conducted among children whose ages were between 2 and 15 years. They were randomized into parental presence and parental absence (un-accompanied) or control groups. The anxiety levels of children and parents in both groups were compared at baseline, separation and during induction of anaesthesia.
Results
The ages of the children ranged between 2 and 15 years with a mean age of 6.78 ± 2.50 years. The mean age of patients in the parental presence at induction (PPIA) was 7.14 ± 3.68 years while in the control group was 6.42 ± 3.31 years. The difference was not statistically significant, p < 0.05. The mean anxiety score of patients in the PPIA at reception, separation and induction of anaesthesia were 26.6 ± 9.2, 38.4 ± 18.3 and 54.1 ± 22.8 compared to 27.3 ± 8.04, 41.4 ± 21.7 and 58.6 ± 23.1 in the control group respectively, p < 0.05. The mean anxiety score of parents in the PPIA at reception, separation and induction of anaesthesia were 52.2 ± 6.7, 51.7 ± 7.8 and 51.9 ± 7.9 compared to 53.0 ± 6.5, 52.4 ± 6.2 and 52.9 ± 7.9 in the control group respectively, p < 0.05. Among the cohort of preschool age group, children in the control group were more anxious at induction compared to the PPIA group, p = 0.01. As the age increases, the anxiety state of the children decreases, t = − 0.398, p < 0.001. The mean score of parental satisfaction in the PPIA and the control groups were comparable, 8.1 ± 7.1 vs 7.3 ± 1.1 respectively, p = 0.395.
Conclusion
The presence of parents during induction of anaesthesia did not influence the anxiety states of children in our study. Anxiety at induction tends to reduce as the age of patients increases.

Vanadium oxide nanomaterial was successfully prepared on conductive substrate via a simple and facile chemical route with no binder or additive. The film was characterized to investigate its microstructural, optical, electrical and electrochemical properties. The SEM micrographs of the annealed film presented enabling environment that is required for effective photocatalysis. It also demonstrated enhanced interaction between the film and the substrate and adequate pore size distribution that can allow free electrolytic ion intercalation/deintercalation for efficient supercapacitive response. EDX confirmed the elemental composition of the film. XRD and Raman spectroscopy showed substantial characteristic peaks that are attributes of orthorhombic crystal structure of V2O5 powder. Optical studies showed that the film exhibited high visible light transmittance and its energy band gap was found to be 2.77 eV. Pseudocapacitive performance of the V2O5 electrode was investigated via a three-electrode cell configuration. The film electrode exhibited highest areal capacity of 1.18 μAh cm⁻², energy density of 0.485 μWhcm⁻² at a power density of 107.71 μWcm⁻² and current density 0.25 mAcm⁻², moderate charge transfer resistance and superior cycling stability. The study demonstrated the viability of V2O5 film as electrode material for the development of high-performance supercapacitors.

This concluding part of the larger paper evaluates some aspects of the Nigeria's vulnerability to the impacts of climate change and discusses potential adaptation strategies that can help in coping with or reducing the impacts of the change in the agriculture and forestry sectors. The vulnerabilities of the various parts of the country were computed, using a wide range of socio-economic parameters and physical environmental factors. The results show that there had been important variability in the rainfall and temperature regimes which 'expose' the country to severe impacts of climate change. The vulnerability assessment further shows that the country's resilience to climate change impact is very weak especially in the Sudano-Sahelian zone. Considering the nature of the vulnerabilities, the paper proposed a number of adaptation strategies mainly in the Agriculture and Forestry sectors. The paper concludes that development and implementation of appropriate policy instrument will be important in ensuring that the country effectively addresses its adaptation challenges.

To make the MDGs a reality, especially as it affects the built environment, and to conform with the UN Agenda 21 and Habitat Agenda summed up in the concept of urban physical sustainability, there is a need to rapidly improve the quality of decisions on land use, conversion and urban renewal in developing countries, especially with regards to physical developments. The potentials of SDSS in determining optimum sites for physical developments within the built environment was the focus of this study. The SDSS developed took into consideration existing and future planning scenarios with the aim of creating a sustainable built environment. To do this, a framework for capturing existing landuse was generated and the SDSS used to generate physical development expansion scenarios of the Obafemi Awolowo University, Nigeria. The system facilitated integrated procedures for determining optimal sites for incremental physical development in such a way as to minimize impact on other aspects of development. The application of this system shows that planning especially as it relate to the urban environment can be made more flexible, dynamic and responsive to timely decisions on geographic space.

The study examined relative poverty among migrant men and women in rural border communities of the Oyo State. Three ruralborder settlements were randomly selected in Atisbo and Saki-west Local Government Areas (LGAs) of Oyo State. Two hundred and
four (204) questionnaires were administered to the father and mother in 102 migrant households and 198 questionnaires were
retrieved for analysis. Using Principal Component Analysis (PCA), the study revealed that women have a higher poverty level than
men. Also, the Principal Component Analysis revealed that the high loadings of factors on component one (Dwelling Conditions), for
both men and women, imply inadequate living conditions. This indicates the need for improved dwelling conditions for the migrants
and also the need to focus on gender-based poverty interventions especially among females, as they are more affected by poverty.

In an industry where the choice of a procurement method is haphazard, developing a decision support system to guide clients in their choices is needed. This research work was aimed at developing a framework using the multi-attribute utility approach. Public clients' prioritized factors for cost categories of building types and the suitability of a procurement method achieving a selection criterion (utility coefficients) were established. Then using the weighted sum model (i.e. additive utility), the procurement method with the largest preference value was determined for each cost category and building type. The model revealed that, for a residential project of up to N100 million (Naira) cost category, taken into consideration public clients' priority rating, design – bid – construct (D-B-C) was the most appropriate procurement option. A trend emerged that for a building project of up to N100 million (Naira), the design – bid-construct, was the most appropriate for all building types. While for a building project of above N500 million (Naira), the management contracting was the most appropriate procurement option for all building types.

Peri-oral injuries are common findings in paediatric patients; however, tongue injury following entrapment in bottles and cans is rare and has not been reported in our locality. A case of a 9- year old previously healthy female child who got her tongue tightly entrapped in an half opened aluminium milk can while in school is hereby presented. This case highlights the result of careless and often dangerous play and misadventures of children and the challenge of management. It calls for vigilance and close supervision of children by caregivers at home and at school. Early presentation, immediate intervention and treatment can prevent grave consequences.

This study fabricated and characterized a self-sustaining hydrogenous content clay-polyethylene composite opted for ionizing radiation shielding. Composites designated A–G were fabricated each containing 0–30 wt% of recycled low density polyethylene (LDPE), respectively. To know the effects of the incorporated LDPE on the morphology, microstructural, compressive strength, thermal property and displacement effect on the vital elements were studied using scanning electron microscopy (SEM), X-ray diffractometry (XRD), universal mechanical testing machine, differential thermal analysis (DTA), Rutherford backscattering (RBS) technique and particle induced X-ray emission (PIXE), respectively. The bulk densities of the clay composites ranged between 1.341 and 2.030 g/cm3. The samples’ XRD analysis revealed similar patterns, with a sharp and prominent peak at angle 2θ equals ~26.11°, which matched with card number 16-0606 of the Joint Committee on Powder Diffraction Standards (JCPDS) that represents Aluminum Silicate Hydroxide (Al2Si2O5(OH)4), a basic formula for Kaolin clay. The compressive strength ranged between 2.52 and 5.53 MPa. The ratio of Si to Al in each composite is about 1:1. The dehydroxylation temperature for samples ranged between 443.23 °C and 555.23 °C.

Antimicrobial delivery systems are useful tools to control biofilm growth on abiotic surfaces such as urinary catheter. The present study examined whether nanostructured lipid carriers coated with chitosan (NLC-chitosan) affected the growth of uropathogenic biofilms of Escherichia coli. NLC-chitosan was prepared using the emulsion and sonication method, and further characterized with respect to particle size, polydispersity index, and zeta potential. After determining the minimum inhibitory and bactericidal concentrations, E. coli biofilms were grown on catheter specimens (following a preliminary study in which E. coli was found to adhere better to the catheter surface than glass slide and plate). At the 48, 72, 96, and 120 h of growth, they were exposed to 0.9% NaCl solution (negative control), 0.12% chlorhexidine solution (positive control), or NLC-chitosan (final chitosan concentration of 0.28%). After 24 h of treatment, the biofilms were collected to analyze their bacterial viability. NLC-chitosan preparation had bimodal particle size distribution with mean size of 292.9 ± 2.5 nm and polydispersity index of 0.24 ± 0.03 and positive zeta potential (+19.1 ± 0.2) indicating the nanoparticle coating by chitosan. Compared with the control groups, NLC-chitosan affected bacterial viability of biofilms at all ages studied (p<0.05). NLC-chitosan can effectively control the growth of young and mature biofilms of uropathogenic E. coli.

The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables-COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60-3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20-0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

Background: We examined the performance of different Machine Learning Algorithms while also comparing two methods of voice assessment to look at the workability of automating triage of patient that will need prompt office laryngoscopy. Methods: We recruited consecutive adult subjects excluding those with a history of being regular singers or choristers in the past one year and those with the previous history of laryngeal trauma. We then carried out the perceptual voice assessments on the GRBAS Scale and also obtained the basic acoustic parameters of the voice samples. Laryngeal examinations with 70-degree Hopkins’ Rod were then carried out by another examiner for all the participants to identify gross laryngeal changes or lesions. We then evaluated each machine learning algorithm comparing the perceptual and acoustic parameters in determining how well each algorithm predicts the presence of those categorized with having lesion or not by the laryngeal examination. Results: One hundred and twenty respondents were analyzed out of which 89(74.2%) were females. The mean age was 46.5 ± 9.2 years. The perceptual evaluation generally outperformed the acoustic evaluation. Also, the Naïve Bayes Classifier (NBC) outperformed other algorithms with a F1 score of 0.55 followed by Artificial Neural Network (ANN) with the score of 0.53. However, the ANN outperformed the other with regards to the Area-under-the-curve (AUC). Conclusion: When these metrics are taken together, the ANN still remains the best algorithm for this dataset. We are however cognisance of the needed improvement to the various aspects of this work including a larger dataset more scientific sampling.

Portable electronic devices require a small volume self-powered energy system that can combine fabrication of energy harvesting and storage devices in one plane. This study focuses on fabricating novel all-oxide photovoltaic and supercapacitor devices based on MoO 3 , V 2 O 5 , and Co x O y thin electrodes prepared by a two-electrode cell arrangement. The fabricated devices were tested using solar simulator and potentiostat at ambient temperature. The power conversion efficiencies of the fabricated photovoltaic devices were found in the range of 0.17-0.39% depending on buffer layer characteristics. It therefore suggests that V 2 O 5 and MoO 3 can buffer photovoltaic processes by lowering the conduction band offset in the proximate Co x O y absorber. Pseudocapacitive behavior of MoO 3 /Co x O y ||MoO 3 /Co x O y and V 2 O 5 /Co x O y ||V 2 O 5 /Co x O y planar devices showed that they delivered maximum specific areal capacity values of 0.694 and 0.778 μAhcm − 2 respectively at discharge current density of 0.1 mAcm − 2. They also showed considerably low reduction in energy density (about 38.7%) even at a remarkable increase in power density of about 450% (at a high current density of 1.0 mAcm − 2). In addition, the symmetric microsupercapacitors showed excellent retention of capacity even after 5000 cycles. These results generally indicate the reliability of the fabricated devices in the development of portable electronic components for energy application.
