Effect of Time Delay in the Stability Analysis of Cholera Epidemic-Endemic Disease Model
Get PDFCholera as a disease is a kind of acute diarrhea caused by bacteria Vibrio cholerae. A nonlinear delayed mathematical model with environmental factor for the spread of infectious disease cholera is proposed and analyzed. A mathematical model for cholera was improved by adding a time delay that represents the time between the instant at which an individual becomes infected and the instant at which he begins to have symptoms of cholera disease. It is assumed that all susceptible are affected by carrier population density. The model is analyzed by stability theory of differential equations and computer simulation. We prove that the delayed cholera model is biologically meaningful and analyze the local asymptotic stability of the equilibrium points for positive time delays. Both the disease-free (DFE) and endemic equilibria are found and their stability investigated using the Routh-Hurwitz stability criterion method. Next Generation Matrix (NGM) method was used to get the basic reproductive numbe

Dissipative Non-Slip MHD Nanofluid Flow with Variable Viscousity and Thermal Conductivity in the Presence of Arrhenius Chemical Reaction
Get PDFThis research investigates the intricate dynamics of dissipative non-slip magnetohydrodynamic (MHD) nanofluid flow, characterized by variable viscosity and thermal conductivity, under the influence of an Arrhenius chemical reaction. The inclusion of the Arrhenius chemical reaction adds complexity through heat generation or absorption, impacting temperature and concentration gradients. The study is motivated by the extensive applications of nanofluids in engineering and industrial processes, where precise control of heat and mass transfer is critical. We develop a comprehensive mathematical model that incorporates the variable properties of the nanofluid, the effects of the Lorentz force due to the applied magnetic field, and the temperature-dependent reaction rates dictated by the Arrhenius equation. The formulated governing equations were non-dimensionalised to identify the flow governing parameters. Finite Element Method (FEM), grid generation, solution algorithms, and post-processing to analyse velocity, temperature, and concentration distributions were used to obtain the numerical methods to solve fluid flow problems based on the Navier-Stokes equations, involving concepts of discretization. pdsolve subpackage in Maple 2023 was used to numerically solve PDEs with specific initial and boundary conditions, incorporating the plot and display commands for graphical analysis, and the results are presented and discussed. The findings reveal that the interplay between parameters like Hartmann number, Darcy parameter, and heat generation or absorption profoundly influences flow behaviour and thermal characteristics. The reactivity parameter is crucial, dictating the rate of chemical reactions and affecting system dynamics. This research enhances understanding of the interdependencies among fluid properties, chemical reactions, and external parameters in nanofluid flows. 
Botswana Coal: Navigating Economic Diversification and Climate Commitments
Get PDFThis paper considers the ethical dilemma posed by the Paris Climate Agreement considering the abundant coal exploitation opportunities in Botswana. The estimated 200 billion tons of coal was initially viewed as an opportunity to diversify the Botswana economy away from diamonds. Coal is currently used locally for electricity production and other small scale domestic uses. This paper mainly discusses thermal coal as opposed to coking coal commonly referred to as Met-coal. Lucrative prices on world markets coupled with demand in India and China for coal, Botswana with its massive coal deposits, one of the largest in world, can develop a new export sector which would diversify the diamond dependent economy. In 2012 the Government of Botswana released a Coal Road Map as it then envisaged coal as one of the more propitious areas for economic diversification. However, the potential to develop this export sector has been seriously challenged by the Paris Climate Agreement decision to move away from coal. In the wake of this treaty countries like China and Japan have refocused their efforts in developing renewable energy and this has negatively hampered Botswana’s economic ambitions. 
Effects of Dietary Oregano (Origanum vulgare L.) Leaf Powder on Meat Quality of Broiler
Get PDFThe experiment was carried out in the Teaching and Research Farm of the Department of Animal Science, Faculty of Agriculture Usmanu Danfodiyo University, Sokoto, Nigeria, to determine the effects of dietary oregano leaf powder on meat quality of broiler meat. The diets were supplemented with oregano leaf powder at 15g/kg, 20g/kg, 25g/kg and 0g/kg (control group), represented as TI, T2, T3 and T4, respectively, dietary oregano leaf powder did not affect muscle pH a* values of broiler meat (P>0.05). However, oregano leaf powder significantly affected b* value, water holding capacity, drip and cooking losses. Higher inclusion level (25g) of oregano leaf powder improves meat quality parameters while supplementation of up to 15g did not affect most of the meat quality parameters. The study recommended 25g inclusion levels of oregano leaf powder due to the positive effects on meat quality parameters of broiler chicken meat. Further studies on the mode of action of oregano leaf powder using different species of poultry on meat quality may be commercially interesting. 
Exploring the Environmental Effects of Urbanization in Monrovia
Get PDFMonrovia, the capital city of Liberia, is undergoing rapid urbanization, leading to significant ecological and environmental challenges. This study aims to investigate the temporal and spatial changes in urbanization and their impact on the ecological environment in Monrovia from 2015 to 2023. Utilizing Landsat satellite images, OpenStreetMap data, and AQICN atmospheric particulate data (PM2.5 and PM10). We analyzed urban patterns, building dynamics, traffic networks, and population growth. Our methodological approach involved spatial analysis and temporal comparisons to assess land use changes and their ecological consequences. Our findings indicate substantial land use changes, with a notable increase in residential areas at the expense of natural and agricultural lands, resulting in habitat fragmentation and biodiversity loss. Economic growth in the central business district has exacerbated ecological degradation, while expanded road networks have increased surface runoff and habitat fragmentation. Air quality analysis shows rising levels of PM2.5 and PM10, posing significant health risks to residents. Additionally, the reduction in water bodies and forest cover has degraded water quality and heightened flood risks. This study underscores the urgent need for sustainable urban planning practices, including the adoption of renewable energy sources, emission control technologies, and enhanced air quality monitoring. Furthermore, community-based approaches and citizen science activities are essential for engaging local residents in pollution monitoring and advocacy, fostering partnerships for the sustainable development of Monrovia. Our research highlights the critical need for integrated strategies to mitigate the adverse effects of urbanization on the environment and public health.
