Munavu RM, Ogutu DM, Wasanga PM. Sustainable articulation pathways and linkages between upper secondary and higher education in Africa.; 2008. AbstractWebsite

Abstract: The recent and rising increase in enrollment at th e primary school level since the
introduction of th e FPE in 2003 has led to a corresponding and signif icant rise in enrollment
rates at the secondary school level. This has translated into an increased demand for higher
education in the country. The demand for higher education is driven by the realiz ation that
this level of education forms the princi pal pillar of development. The current development
agen da in Kenya is inspired by the realization that there are many available options and …

Munavu RM. "Health and Natural Resources: The Extraction of Useful Chemicals from Plants and their Impact on Socio-Economic Development.". 2005. Abstract

Poverty reduction strategies in developing countries are based on the need to develop and
improve the quality of life of people. The successful strategies link wealth creating activities
of adding value to local resources with employment creation. These strategies lead to
increased capacity to produce needed consumer goods such as food, fuel, construction
materials, textiles and pharmaceuticals starting from local resources. Most value-adding
transformations of materials to consumer goods use chemicals conversion processes

Investigation of the Tanzanian Dendrosenecio kilimanjari subsp. cottonii resulted in
the isolation of the cinchona alkaloid, cinchonidine (2). Conversion of cinchonidine to deoxy-
cinchonidine was achieved in high yield using zinc dust in aqueous sulphuric acid. This
illustrates the first reduction of a quinoline system using these reagents.

Kamau RK, Osoti AO, Njuguna EM. Department of Obstetrics and Gynaecology, College of Health Sciences, University of Nairobi, P.O. Box 1%76-00202, Nairobi, Kenya. BACKGROUND: Cancer of the uterine cervix is the most common female cancer in Kenya. Despite being preventable, it is often diagnosed when it is already late. For this reason, only palliative therapy is provided. Hence, it is expected that their daily routines and that of their caregivers are severely disrupted. OBJECTIVES: To determine the extent to which diagnosis and treatment of inoperable cervical carcinoma affects quality of life (QOL). DESIGN: Cross-sectional descriptive study. Setting Radiotherapy Department at the Kenyatta National Hospital. SUBJECTS: Women undergoing radiotherapy for inoperable cervical cancer. RESULTS: There is high prevalence of profound disruptions in nearly all domains of QOL. In the social domain, between 33% and 44% had the perception that family members and friends had withdrawn social support. Reduction in various economic facets was reported by 47.4%-52.6%, with 44.7% reporting a fall in the overall living standards. There were significant changes in the sexual domain, as a result in which 28.3% reported marital discordance. In the personality domain, decreased self-esteem and self-projection in life occurred in 30.9% and 36.2% respectively. On functional outcomes (EORTC QLQ-C30), only 32%-41% reported not being affected in the various facets of emotional function. Physical functions were affected in 19%-79%, role functions in 69%-75%; symptoms in 49%-80%; cognitive functions in 46%-56%; social functions in 63%-71% and financial aspects by 63%. On global QOL, 53% and 47% respectively reported high level disruption in overall physical health and overall QOL. CONCLUSION: Severe deterioration of QOL occurs as a result of diagnosis of inoperable cervical cancer and subsequent therapies. For this reason there is need to establish severe disease and end-of-life research and management services that would ensure better coping with cancer for patients and for home-based caregivers.
