Site Suitability Analysis for Landfill in an Industrial Area in Nigeria

This study was set against the background of identifying management strategies to combat the menace associated with poor solid waste management in urban areas of Nigeria. Therefore, it becomes highly necessary to determine suitable sites for landfill. Using remote sensing and geographic information tools and technologies the study identified the scenes of present dump sites; evaluated the conditions for selecting landfill sites; and determined suitable landfills in Ajaokuta, Nigeria. Data for the study were sourced from Sentinel-2A, 2021. Integrated GIS-based analysis using multi-criteria evaluation method was employed to scrutinise the appropriateness of the existing dumpsites for siting landfills. However, with reference to Federal Environmental Protection Agency (FEPA) guidelines, results of buffering and proximity analyses indicated that none of the existing dumpsites could be converted to landfill sites. Moreover, a fuzzy overlay of all the criteria considered was employed to identify and propose the most suitable areas for solid waste disposal sites in the study area. Based on the official stipulated distance, new sites were proposed for landfills. The study emphasised the increasing mounds and improper disposal of municipal solid wastes in Nigerian urban centres which have become too agonising and repulsive to sights. Nevertheless, if the recommendations of this study are taken with utmost seriousness, any unexpected outbreak of epidemic and environmental pollution will be greatly avoided in the study area

Correlation between Socio-Economic Characteristics and Housing Quality of Residential Neighbourhoods in Akure, Southwest Nigeria

There is a general paucity of explanations for the emerging social and spatial changes in the pattern and socio-economic traits of urban residential housing units in Nigeria. Hence, this study examined the spatial pattern of residential neighbourhoods; assessed the quality of residential housing units; and evaluated the correlation between the socio-economic position of respondents and housing quality in Akure, Nigeria. Data were derived from the household questionnaire, remotely sensed data (Landsat 8 OLI/TIR, 2021), a Google Earth map, a Street Map of Akure Township, and personal observations. The study adopted a step-wise sampling technique to select 383 samples from 139,069 heads of households in Akure in 2021. Data were analysed using percentage distribution, Pearson Correlation Coefficient, and t-test. Results indicated varying housing qualities across three residential zones in Akure, Nigeria; houses in the low-density residential areas were of better quality than the other residential zones. The quality of houses occupied was influenced by the type of occupation, level of education and average annual income of residents. The study concluded that inadequate housing facilities are fundamental to the observed deteriorating housing qualities in the study area. Therefore, the study suggested improvement of the existing infrastructures and the provision of new ones in the study area. The main contribution of this study is to proffer solutions for a sustainable housing delivery system to facilitate a better quality of life in Nigerian urban centres

Pedestrians’ crossing behaviour in south-western Nigeria

This study examined the pedestrians’ safe and unsafe behaviour before and during street crossing in three cities in South Western Nigeria. 1,214 pedestrians were observed at crossing sites using direct observation approach. The data were analysed using descriptive statistics, chi-square, Analysis of Variance (ANOVA) and logistic regression. In all, 730 (60.1%) of the observed pedestrians were male, and 484 (39.9%) were female. The analysis of the data showed that safe crossing practices were generally high, as over 50% of pedestrians at different stages of the crossing process were categorized as exhibiting safe observation behaviour. In terms of crossing tempo, Chi-square test revealed significant difference between male (65.1%) than female (56.0%) pedestrians (χ2=10.12, d=1, p=0.000). While ANOVA showed significant variation in the risky crossing behaviour among the cities (F (2, 1211) =71.93, P< 0.01). Logistic regression analysis showed that adult pedestrians are 0.79 times more likely to exhibit safe crossing behaviour than younger pedestrians and pedestrians are 0.42 times more likely to exhibit safe crossing when vehicles are moving on one side of the road than when there is no vehicular movement. The study suggests measures to enhance safe street crossing behaviour in the sampled cities and other cities in Nigeria

Mathematical Analysis of Sensitive Parameters on the Dynamical Transmission of HIV-Malaria Co-infection

Malaria disease increases the mortality rate of HIV patients. In this work, a mathematical model incorporating an infected, undetected, and treated set of people was developed. The analysis showed that the model is well-posed, the disease-free equilibrium for the model was obtained, and the basic reproduction number of the HIV-malaria co-infection model was calculated. The 14 compartmental models were analyzed for stability, and it was established that the disease-free equilibrium of each model and their co-infections were locally and globally asymptotically stable whenever the basic reproduction number was less than unity or endemic otherwise. Based on the sensitivity analysis, the parameter that has the greatest impact is the contact rate; therefore, it is recommended for public health policies aimed at reducing the burden of these diseases in co-endemic regions

A novel tuberculosis model incorporating a Caputo fractional derivative and treatment effect via the homotopy perturbation method

Abstract Background Tuberculosis (TB), caused by Mycobacterium tuberculosis, is a contagious infectious disease that primarily targets the lungs but can also impact other critical systems such as the bones, joints, and neurological system. Despite significant efforts to combat TB, it remains a major global health concern. To address this challenge, this study aims to explore and evaluate various tuberculosis control approaches using a mathematical modeling framework. Results The study utilized a novel SEITR mathematical model to investigate the impact of treatment on physical limitations in tuberculosis. The model underwent qualitative analysis to validate key aspects, including positivity, existence, uniqueness, and boundedness. Disease-free and endemic equilibria were identified, and both local and global stability of the model was thoroughly examined using the derived reproduction number. To estimate the impact of each parameter on each compartment, sensitivity analysis was conducted, and numerical simulations were performed using Maple 18 software with the homotopy perturbation method. The obtained results are promising and highlight the potential of the proposed interventions to significantly reduce tuberculosis virus prevalence. The findings emphasize the significance of fractional-order analysis in understanding the effectiveness of treatment strategies for mitigating tuberculosis prevalence. The study suggests that the time fractional dynamics of TB treatment correspond to the treatment’s efficacy, as the conceptual results showed that non-local interactions between the disease and the treatment may lead to more accurate ways of eradicating tuberculosis in real-world scenarios. These insights contribute to a better understanding of effective treatment strategies and their potential impact on tuberculosis control and public health. Conclusions In conclusion, scientists, researchers, and healthcare personnel are urged to take action and utilize the discoveries from this research to facilitate the eradication of the hazardous tuberculosis bacteria

Spatial Preference of Urban Residential Location in Osogbo, Nigeria

This study examined the spatial preference of urban residential location in Osogbo, Osun State, Nigeria. It identified the types and qualities of residential housing units; and examined the factors influencing the choice of residential location in Osogbo. Data were obtained from primary and secondary sources. Primary data were obtained through field observation and administration of questionnaire to 431 households. Secondary data were sourced from topographical map and the township map of the study area. In view of the observed inequalities in the number and density of buildings, the study area was divided into three zones: Zone ‘A’ (the old core), Zone ‘B’ (intermediate zone) and Zone ‘C’ (the outskirts). For easy identification of sample points, each of the zones was further divided into ten quadrants of equal sizes. Relative Importance Index (RII) indicated that occupation (RII = 0.769), house quality (RII = 0.768), nearness to place of work (RII = 0.766) and physical quality of the neighbourhood were the principal indices of residential location. Furthermore, results indicate that nearness to children’s schools (X₁₃) constantly recorded the least RII value; it was the only factor with RII value of less than 0.5 both at the zonal and overall levels of assessment. The study concluded that low-income households and or whose heads have below college education or completely uneducated were satisfied with any house in any location where the rent is affordable and provided easy and quick access to their places of work

A caputo fractional order epidemic model for evaluating the effectiveness of high-risk quarantine and vaccination strategies on the spread of COVID-19

The recent global Coronavirus disease (COVID-19) threat to the human race requires research on preventing its reemergence without affecting socio-economic factors. This study proposes a fractional-order mathematical model to analyze the impact of high-risk quarantine and vaccination on COVID-19 transmission. The proposed model is used to analyze real-life COVID-19 data to develop and analyze the solutions and their feasibilities. Numerical simulations study the high-risk quarantine and vaccination strategies and show that both strategies effectively reduce the virus prevalence, but their combined application is more effective. We also demonstrate that their effectiveness varies with the volatile rate of change in the system’s distribution. The results are analyzed using Caputo fractional order and presented graphically and extensively analyzed to highlight potent ways of curbing the virus

Knowledge and affective traits of physiotherapy students to provide care for patients living with AIDS.

Purpose: This  study  aimed  to  assess  Nigerian physiotherapy students’ knowledge and their affective traits in caring for patients living with AIDS (PWA).Methods: Nigerian students (N=104) in four training programs were surveyed using a 43-item questionnaire that elicited information on the  students’  demographics  characteristics,  knowledge  levels  on AIDS transmission, universal precaution and pathophysiology, their feeling  of  preparedness,  comfort,  ethical  disposition  for  PWA  and their  willingness  to  evaluate  and  provide  care  to  PWA  in  different clinical scenarios.Results: Overall  the  students  showed  unsatisfactory  know ledge  of universal  precaution  and  AIDS  pathophysiology  and  did  not  feel comfortable or prepared to care for PWA. The students did not also show  satisfactory  ethical  disposition  and  may  be  unwilling  to  care for PWA. The students’ knowledge levels on AIDS transmission and willingness were influenced by religious affiliation while feeling of comfort and ethical disposition were influenced by gender and knowing someone living with AIDS. They were more unwilling to provide whirlpool wound care procedures and chest physiotherapy compared to providing gait training, therapeutic exercise and activities of daily living training for PWA.Conclusion: The study identified the need to improve the curriculum on AIDS and recommends clinical clerkship and a methodical and sequential exposure of students to cases during clinical rotations

Sero-prevalence and determinants of Hepatitis B among a cohort of HIV-infected women of reproductive age in Nigeria.

IntroductionSub-Saharan Africa houses over two-thirds of the 37 million people living with human immunodeficiency virus (HIV) globally and of this, 5-20% are co-infected with Hepatitis B virus (HBV). This is double jeopardy, especially for women of reproductive age in these settings, who can transmit both viruses vertically as well as horizontally to their children. The objectives of this study were to investigate the prevalence and determinants of HBV among women of reproductive age living with HIV.MethodsThis was a cross-sectional study of HIV-infected women of reproductive age in Benue State, Nigeria. Participants were eligible for the study if they were HIV-infected women (ages 18-45 years) receiving care from any of the selected study sites. A global rapid hepatitis B surface antigen (HBsAg) antibody test strip was used to test for HBsAg in plasma. A pretested questionnaire was used to collect data on sociodemographic, clinical and lifestyle characteristics of participants. We estimated prevalence of HBV infection and used multivariable logistic regression to determine factors associated with the infection at a significance level of ResultsA total of 6577 women were screened for HBsAg. The prevalence of HBV was 10.3% (95% CI: 9.5-10.9%). Age, parity and male partner's HIV status were found to be associated with having HBV infection. Compared to women older than 40 years, the odds of HBV infection increased significantly with increasing age until age 35 years and decreased significantly with increasing parity (versus no parity). Women with HIV-infected partners and those without a partner had higher odds of HBV infection compared to women with HIV-negative partners.ConclusionHBV is hyperendemic among HIV-infected women of reproductive age in North Central Nigeria. Specific programs targeting HBV testing, vaccination and treatment of all women of reproductive age need to be developed in this resource-limited, high-need setting
