Abstract Hyphaene compressa is an economically important palm in Africa. Despite its significant role in the livelihoods of rural communities, the diversity of doum palm is poorly documented and studied. In addition, it has no model descriptor that can aid such studies. Ninety H. compressa accessions collected from Northern, Eastern, and Coastal regions of Kenya were examined to determine the morphological variability of the vegetative and fruit traits of H. compressa and to identify its mor...
Abstract A gradual shift to biofuels development was considered advantageous in reducing the pollution and other challenges associated with fossil fuels. Specifically, biodiesel production is one of those options prioritized in the literature. Herein, we demonstrated how a modified activated charcoal sample and chromium oxide can catalyze the upgrading of groundnut oil into fuel-grade biodiesel at the laboratory scale via trans-esterification with methanol. The charcoal-based catalyst was ...
ABSTRACT The online rental system is a web-based platform designed to facilitate the process of renting various goods and services over the internet. It provides a convenient and efficient way for individuals and businesses to connect, negotiate, and engage in rental transactions. The system offers a user-friendly interface that allows renters to browse through a wide range of available items or services, such as vehicles, equipment, properties, and more. Users can search for specific rentals...
This research focuses on enhancing the optimization process of the classical ground state energy for hydrogen molecules, which is known to be -1.1373 Ha. Various well-known optimization algorithms such as Gradient Descent Optimizer, Adagrad Optimizer, Adam Optimizer, RMSProp Optimizer, and Momentum Optimizer are employed to explore their convergence behavior and their proximity to the precise ground state energy. The analysis extends to examining potential energy curves to gain insights into ...
The importance of the US Dollar to a mono economy and import dependent nation such as South Africa cannot be over emphasized in the most notable transactions that takes place in any economic process must have a direct or indirect connection with the dollars. The aim of the study is to find the relationship between American dollar and South African rand. The statistical relationship between inflation and petrol price were investigated using secondary data. The correlation coefficient...
Maternal carrier status of hepatitis B has been associated with excess sons while maternal immunity to it has been associated with excess daughters at birth. However, the proportion of males at birth (sex ratio) is relatively low in Sub-Saharan Africa despite the relatively high prevalence of hepatitis B. However, no known study has tested this hypothesis in the Ghanaian population, hence the aim of the study. The study was cross-sectional between January and September 2023 at the Tamale Cent...

Abstract/Overview In this paper, a latent infection susceptible–exposed–infectious–recovered model with demographic efects is used to understand the dynamics of the COVID-19 pandemics. We calculate the basic reproduction number (R0) by solving the diferential equations of the model and also using next-generation matrix method. We also prove the global stability of the model using the Lyapunov method. We showed that when the R0 < 1 or R0 ≤ 1 and R0 > 1 or R0 ≥ 1 the disease-free ...
Abstract The characterization of the group of units of any commutative ring has not been done in general, and previous studies have restricted the classes of rings or groups under consideration. In this work, we determine the structures of the groups of units of commutative completely primary finite rings R of characteristic pn for some prime integer p and positive integer n.
Abstract/Overview Cotton production is on the decline due to ever-changing environmental conditions. Drought and salinity stress contribute to over 30% of total loss in cotton production, the situation has worsened more due to the narrow genetic base of the cultivated upland cotton. The genetic diversity of upland cotton has been eroded over the years due to intense selection and inbreeding. To break the bottleneck, the wild cotton progenitors offer unique traits which can be introgressed...
Abstract/Overview A major factor driving changes in land use and land cover (LULC) is the human population growth associated with an expanded agricultural production. In the Lambwe valley in Homabay County, Kenya, the most important reason for accelerated population growth in the last decades was the control of the tsetse fly, the biological vector of trypanosomiasis. The goal of our study is to quantify the changes of LULC in the Lambwe valley in the last 30 years, giving special attenti...
Abstract Let R be a completely primary finite ring and J be its Jacobson radical. A class of such rings in which J4 = (0), J3 = (0) has been constructed. Moreover, the structures of their groups of units have been determined for all the characteristics of R. Mathematcs Subject Classification: Primary 13M05, 16P10, 16U60; Secondary 13E10, 16N20
Abstract/Overview Neglect and under-utilization of legumes such as soybeans and bambaragroundnuts are the reason for increased food insufficiency in the Lake Vic toria basin. Diversification of legumes into the cropping systems of LakeVictoria basin ensures protein rich diets and improved soil fertility. Thisstudy was carried out to evaluate agronomic characters of two soybean vari eties and two bambara groundnut landraces cultivated on different soils ofLake Victoria basin. Seeds of two ...
