Word processors are one of the most widely used software applications in our time and have greatly contributed to the shift of paperless office. It has brought drastic changes in the way business documents are created, edited and stored. However word processors have over the years proven to be susceptible and have been successfully exploited to launch catastrophic attacks which have been costly to various states (countries), organizations and individuals. The main objective of this resea...
E-learning has enhanced the way students think and learn over time. Different studies show that students appreciate facilities offered through the e-learning process. It has also proven to be a very useful tool by bringing education closer to the learner, hence, learner-centred. A point to note about e-learning is the ability to offer a wide range of information access, storage and education curriculum. Institutions of higher learning moderate and harmonize this information between instr...
Abstract The major lithostratigraphic units of the eastern Dahomey Basin are the Araromi, Ewekoro and Akinbo Formations. Field studies show that the Araromi and Akinbo Formations contain shaly facies, while the Ewekoro Formation contains essentially fossiliferous limestones. The Araromi shales are dark and bituminous, while those of the Akinbo are fissile and concretionary. Selected subsurface and outcrop samples of these lithotypes were analysed to ascertain their palaeodepositional environm...
The proliferation of Android smartphones has propagated negative societal issues that resulted in successful arrests of the culprits, forensic examination and prosecution. Other such cases have collapsed due to alteration of forensic evidence as a result of inadequate forensic sound frameworks. The purpose of this study was to develop and evaluate an enhanced forensic framework for Android smartphones with a key focus on data integrity. The research objectives included exploration of roo...
ABSTRACT The knowledge and comprehension of the genetic variation of maize (Zea mays L.) landraces is pivotal for the implementation of measures to address conservation and improvement. The purpose of this study was to assess the genetic diversity and relationship among selected maize genotypes in Republic of Tanzania by screening twenty Random Amplified Polymorphic DNA molecular markers.DNA was extracted from 160 maize genotypes and PCR was conducted using twelve informative primers. Ampli...
ABSTRACT Using multiple enrollment can improve recognition performance in fingerprint recognition systems; but there are several technical and operational challenges to implementing multiple enrollment based fingerprint recognition systems. Multiple enrollment based fingerprint recognition systems still have low recognition accuracies, poor matching speeds, and consume a lot of memory making it difficult to implement them in real world scenarios. Also, most of multiple enrollment based finge...
Continuous improvement is a key factor for survival in today’s turbulent business environment. Correspondingly, in today’s business world, software is everywhere. In the whole process of software development, testing is a phase that is often forgotten. Everybody assumes that once the software is developed, it will work flawlessly. However, it often happens not to be so. Moreover, when it does not, we are all unsatisfied and frustrated. Problems with software are a frequent occurrence...
ABSTRACT A cross sectional study was conducted to investigate the prevalence of toxoplasmosis in small ruminants and associated human and animal exposure risk factors. Serological detection of Toxoplasma antibodies was done in 300 goats and 100 sheep sera by ELISA test (Interlab, São Paulo, Brazil). Information on risk factors was collected by interview method, using structured questionnaires. The overall prevalence of toxoplasmosis was 27 and 12% in sheep and goats respectively. Dairy goat...
The presence of aromatics in fuel deters ultra-low sulfur fuel production. Consequently the researcher’s interest has involved the de-aromatization of fuels. Dearomatization would ultimately improve the quality of the fuels in terms of density, cetane number, viscosity etc. In this study, solvent extraction was adopted to de-aromatize a feedstock sample of 20.1 % aromatic and 166 ppm sulfur using acetonitrile. The extraction was performed at low temperatures 25, 35 and 45 °C and ambi...
Secure Voting System‘ is heart of any democracy. There are number of nationwide voting system adopted all over the world, but each of them has their own shortfalls. The remote Internet voting systems still suffer many problems. These are some reasons that, manual voting is still in practice in many developing and developed nations in this internet era. Thus, complete, strongly secured and user friendly ‗E Voting System‘ is need of time. The aim of this thesis is to design a secure ...
ABSTRACT This thesis, Design-Reality Gaps in Open Source Information Systems Development: An Action Research Study of Education and Healthcare Systems in Tanzania, presents a theoretical and empirical informed analysis of Free Open Source Software (FOSS) development in the domain of health and education information systems in Tanzania. Historically, FOSS development has been driven by user-developer communities who are also the users of FOSS applications. The use of Foss applications in ...
A great number of people all over the world suffer from diabetes. Understanding the mechanisms by which amino acids regulate insulin secretion in vivo may reveal novel sites for targeting drugs for the therapy of type 2 diabetes in the future. A descriptive analytical cross-sectional and hospital based study was done. The objectives of this study were to determine in the levels of selected amino acids in patients with diabetes type 2 and to measure the serum levels of insulin in Sudanese...
In Tanzania, and in East Africa in general, bioassessment methods for monitoring and assessing riverine ecosystems are not yet in place. This thesis describes the development of a macroinvertebrate-based bioassessment method for assessing the degree of anthropogenic disturbance in Tanzanian rivers. The hypotheses that, ‘macroinvertebrate assemblages reflect disturbance in river systems’; ‘rivers with similar abiotic features have similar macroinvertebrate assemblages’; and ‘spatio-t...
