ABSTRACT Essential Oils (EOs) are volatile secondary metabolites characterised by a strong odour and widely used for pharmacological and industrial applications. There is dearth of information on chemical compositions and bioactivities of EOs of some fruit trees in Nigeria. This study was therefore designed to extract and characterise the EOs from selected fruit trees, screen the EOs for bioactivity as well as to isolate and characterise non-volatile constituents from Theobroma cacao L. pod-...
ABSTRACT Climate variability is indicated as anomalies in weather parameters such as rainfall and temperature. These are being influenced by greenhouse gas emissions such as carbon dioxide (CO2) and methane (CH4), amongst others. This variability is usually studied using General Circulation Models (GCMs) and empirical models obtained from analyses of data at synoptic weather stations. The GCMs give different predictions from model to model due to parameterisations of microprocesses embedded ...
ABSTRACT Field studies of outcrop samples from part of Anambra basin, southeastern Nigeria, were investigated to unravel the lithofacies distribution, provenance, palaeotectonic history as well as aspects of hydrocarbon potential of the basin. The sandstone facies of the Nkporo, Owelli, Mamu and Ajali Formations are cross bedded, medium to coarse grained, poorly sorted to moderately well sorted, negatively skewed and leptokurtic to platykurtic. Textural plots and multivariate parameters indic...
ABSTRACT Mobile Agent Technology (MAT), remote method invocation and remote procedure calling are the three most widely used techniques for information storage and retrieval in network environments. Previous studies have shown that MAT provides a more efficient and dynamic approach to information storage and retrieval than others. However, for mobile agents to effectively perform their various tasks, a static agent platform must be installed on the computers. These platforms consume more mem...
ABSTRACT Dried, pulverized stem bark and the root bark of Entandrophragma anqolense were separately extracted with methanol. The crude methanolic extract o f the stem and root bark of E. anqolense were subjected to column fractionation and purification . This exercise afforded the Isolation o f methyl angolensate, 2.26% yield from the stem bark and 0.27% yield from the root bark. The effect of the crude methanolic stem bark extract was investigated on indomethacin-induced gastric ulcer in rat...
Abstract The search for new drugs to combat infectious diseases has stimulated the interest of scientists globally due to emergence of Multi Drug-Resistant (MDR) microorganisms. Indigenous medicinal plants are potential reservoir of bioactive compounds from which new active drugs could be obtained, but are yet to be adequately exploited. This study was therefore designed to screen for new bioactive compounds from some indigenous medicinal plants against selected MDR microorganisms. Harungana...
ABSTRACT Free-range chickens are sentinels for the presence of Toxoplasma gondii oocysts in the environment because they feed from ground. T. gondii infected chickens are also an important source of infection for cats that shed environmentally resistant oocysts after eating infected chicken tissues. We surveyed 50 free-range chickens from Oyo State, Nigeria for the presence of T. gondii antibodies using the modified agglutination test (MAT). All chickens tested seropositive with MAT titers of...
ABSTRACT Quality control tests have been undertaken on thirteen mammography systems with the aim of optimizing procedures and patient radiation protection, establishing diagnostic reference levels (DRLs) and establishing quality control (QC) baseline data for the diagnostic mammography practice in Ghana. Quantitative image quality analysis was performed with “ImageJ” software using the “Rose Model” while all other tests were performed using internationally accepted protocols. Results...
Abstract The project aims at providing a user-friendly application to enable Ghanaian small-scale firms to provide better after-sales service support. The provision of effective and efficient door-to-door customer service in Ghana has been a challenge to Small and Medium Enterprises (SMEs). This can be attributed to cost of acquiring technology that can help to streamline processes. However, Geographic Information Systems (GIS) have improved significantly has become accessible in recent years...
ABSTRACT Investigators working in rural communities and small towns in Africa face many obstacles to obtaining a random and representative sample of households for their research. The civic infrastructure used as the building blocks of survey sampling in developed countries are mostly absent in rural Africa. The purpose of the study described in this paper was to pilot an innovative and cost-effective approach to household sampling designed to generate probability samples representative of th...
Abstract Individuals on the Autism Spectrum experience some difficult in recognizing and expressing emotions using their faces. This affects their ability to form long-term relationships and leaves them ostracized from others in our society. This project seeks to develop an application that helps children with autism recognise emotions in order to better place them in our society.
ABSTRACT This capstone project idea is to develop a system called FarmConnect—a mobile application platform that connects investors with smallholder farmers who are seeking funding for their farm operations. Such funding will help the farmer operate at full capacity hence increasing the level of food security in Ghana. FarmConnect will be able to provide interested investors with concrete data that will inform their decision to invest in a chosen smallholder farmer. Also, an example farmer ...
Abstract “Money makes the world go round”. The importance of money has made it a very powerful tool man cannot live without. Thus, it is very important for people to have money when they need it. The mobile phone has developed drastically from a device just for making and receiving calls to one that can be used to take pictures, send emails, connect to the internet and do many other things that at one point in time were dedicated to specific devices such as computers. Mobile phone users i...
Abstract It has been observed that it is stressful for patients on the Ghana National Health Insurance Scheme to get quality health care. This stress is due to congestion at the hospitals that operate under the scheme. The congestion does not only waste the time of the patients but can also cause death. There is also the need of sharing medical and patient information among hospitals that operate under the scheme. Inability of sharing data renders the work of the scheme inefficient. This diss...
Abstract The use of electronic devices such as computers and mobile phones have rapidly increased over time. Technological powerhouses have inculcated some form of speech recognition in their devices and as such, the increase in usage of this devices provides the increase in interaction between humans and speech recognition. Speech recognition involves adequately transcribing spoken sentences or words into text. This interaction is present all over the world, Africa inclusively, and the con...
