ABSTRACT Globally, it is estimated that 1.2 million injecting substance users are HBV infected while 1.7 million live with HIV. Africa is home to about 1.02 million injecting substance users of whom 12.7% are HBV infected while 12.1% live with HIV. In Kenya, the population of injecting substance users is approximately 50,000 most of whom reside in Nairobi and Mombasa cities. Nairobi and Mombasa cities are home to about 23,000 and 27,000 injecting substance users, respectively. The prevalence ...
ABSTRACT Forest logging is a major threat to global biodiversity (Sala et al. 2000) and a growing demand for timber means logging rates are increasing (Perry, Ram & Hart 2008). Consequently, there is a drive to develop forest timber harvesting strategies that maintain biodiversity alongside timber extraction. Attempts are, therefore, being made to integrate conservation into production forests according to ecologically sustainable forest management principles such as themaintenance of stand s...
ABSTRACT Schistosomiasis infects approximately 207 million people worldwide with 90% of the cases occurring in Africa. Kato-Katz, is the standard method of S.mansoni diagnosis, however it is characterized by low sensitivity. Another method of diagnosis is the antibody ELISA, which is highly sensitive but lacks specificity. The PCR test is 98% sensitive and 100% specific but it is costly for use in limited resource settings. The high sensitivity and specificity of the PCR makes it a useful gol...
Abstract The electronic, optical and thermal properties of hexagonal and cubic phases of Ge2Sb2Te5 (GST) have been calculated using density functional theory (DFT) as implemented in the QUANTUM ESPRESSO computer package. GST is successfully applied in optical memory such as rewritable CDs and is a promising candidate for non-volatile electronic memory. In optical storage, the reflectivity contrast can be optimized towards the ultraviolet spectral range, thereby increasing data storage capacit...
ABSTRACT Tomato (Lycopersicon esculentum Mill) is one of the most popular vegetables in the world.Tomato and its products are rich in antioxidants and vitamins C, E and carotenoids. The world consumption of tomato has increased significantly. Despite its importance, its production is below full potential due to the effect of pests and diseases such as bacterial wilt. Bacterial wilt, caused by Ralstonia solanacearum is one of the most devastating, and wide-spread bacterial diseases of crops in...
ABSTRACT Plant-derived compounds could exhibit a direct and/or an indirect antimicrobial activity as antimicrobial resistance modifying compounds. Their effectiveness could further be increased when combined with other bioactive compounds or antibiotics (synergy). A systematic search for plant-derived bioactive compounds, including those which can synergistically act with other bioactive compounds or antibiotics, as resistance modifying agents represents a potential approach to overcoming mic...
ABSTRACT This paper reports on the findings of a research study that investigated on the challenges faced by teachers in the implementation of inclusive education in two of the secondary schools in Lower Gwelo Cluster. The study made use of a mixed method approach .The research methodology was underpinned by a descriptive survey .The specific constructs studied were teachers and administrators .The sample was purposely drawn from 2 schools, 24 teachers and 2 heads of schools in Lower Gwelo c...
ABSTRACT Service Oriented Architecture (SOA) is one of the recent software development paradigms that enable alignment of business processes into integrated services within and outside organizations regardless of the heterogeneity of technologies used. Determining the scope, effort and cost of SOA systems is important to facilitate the planning and eventually successful implementation of software projects. A number of methods have been proposed to estimate effort of building SOA projects. Des...
ABSTRACT Organisational downsizing is a strategy employed by most limping organizations in quest for survival. The strategy can have fatal effects if not properly implemented. The study evaluated organizational downsizing and its subsequent effects to the remaining employees‟ safety and health focusing on Zimasco Kwekwe. This was driven by the premise that organizations must ensure uptight safety and health systems are in place regardless of challenges faced as this cannot be compromised. ...
ABSTRACT Sweet potato (Ipomoea batatas) is one of the crops being considered for the diversification of the staple diet to enhance food security in Zimbabwe in the face of climate change and economic challenges. One of the hurdles preventing adoption of sweet potato as a staple food is its short shelf-life. There has been a call to explore means of preserving sweet potato hence increasing its shelf-life and one method of preservation is processing sweet potato into flour. However, this metho...
ABSTRACT How discipline has been modeled and maintained through corporal punishment among pupils in schools is a controversial issue in the implementation of legal polices from the government. Corporal punishment remains ideal and the order of the day in any academic institution and it had remained an option in the teaching and learning profession and or endeavour. The study focused on the government policy on the implementation of corporal punishment in schools in Mutare urban. The study w...
ABSTRACT This documentation gives in detail how the designer introduced, planned, analyzed, designed and implemented the warehouse distribution management system at TMPnP (Thomas Miekles, Pick and Pay) supermarkets. The designer clearly explained the problem which the organization had that is of using the traditional system in managing their warehouse department. By using the traditional system it gave them disadvantages in recording goods and services received and also monitoring the moveme...
ABSTRACT The term cloud computing is derived from the cloud diagram on the network that represented the Internet for years until a variety of services emerged that allowed computing resources to be accessed over the Internet. The technology extends existing IT capabilities without spending much on new information technology (IT) infrastructure, training new staff and software licence. Case studies from the United States, Europe, Africa and Asia governments’ spectacle cloud adoption servic...
ABSTRACT This study attempts an empirical evaluation of the location of inter city luxurious bus terminals in Metropolitan Lagos. The impacts of these locations in the areas of delays, congestion and pollution were the main foci of this work. Logistic S-shaped curve was used to evaluate the growth pattern of the luxurious bus firms in Metropolitan Lagos. The delays at the terminals were evaluated through direct measurement from the field. The Post-Hoc Test and Least Significance Difference we...
ABSTRACT A study of the two stable isotopes of helium at low temperature was done using statistical mechanics approach. It was assumed that pairs of ~He - iH e were formed creating a new particle in the mixture. Such a mixture exhibits quantum effects at temperatures close to 0 K. A model of pair interaction was used. The partition function of the mixture was used in establishing the chemical potential of the mixture. The case of a particle in a cube of known volume was used. An expression of...
