ncreasing miniaturization of mobile devices marks an important opportunity for the next
generation health care delivery. Mobile health (mHea
lth), existing at the nexus of health and technology
provides a singular opportunity to take health where
it is needed the most. Having had nearly mainstream
adoption, may explain why the developed world is in tandem with health-related Millennium Development
Goals (MDGs). On the other hand, developing countries
still lag behind in meeting the same health-related
goals, yet they continue to report successful stories of mobile technology growth and adoption but no major
usage of the same to deliver healthcare. This resear
ch sought to explore existing mHealth applications to
establish their suitability for use in developing countries such as Kenya to provide home-based care. This was
done by a survey of existing literature and mHealth models, and an architecture developed in light of local
communication infrastructure and local mobile phone abilities. It was established that for developing
countries to take advantage of this leapfrogging technology in health, they would have to take advantage of
the Short Message Service (SMS) that is cheap and accessible to all. A relationship amongst mHealth
stakeholders was considered as key to enhancing the adoption of mHealth in such countries

An Investigation of Project Success for Engineering and Technology-Based Projects in Developing Countries
Marwanga, R.O; Nyangara, F.M; Deleveaux, V.J.
The success or failure of engineering and technology-based development projects is studied in this paper. A sample of one hundred and thirty three (133) completed projects funded by the World Bank are investigated to determine their level of success based on bank criteria and assessments. The assessments mainly focus on the following criteria: relevance of objectives, efficacy, efficiency, sustainability, institutional development impact, outcome, bank performance, and borrower performance. One other dimension that has been downplayed by these assessments is project management success as represented by project schedule and cost. In the current study, the level of project success is evaluated on the basis of bank criteria and performance in project management. A composite project performance index is then derived, planned schedules are compared with final closeout, and budgets are compared with final costs to determine the overall success of these projects. Finally, the effects of project sector, regional location of projects, and project size, on success are investigated. The results show that only about half (50%) of the World Bank projects are successful in achieving their goals. The results also show that the sector of a project, its geographical region, or size have no effect on project success

Analysis of raw iron ores in Kenya: case study of Mwingi north constituency in Kitui county

Accurate prediction of downstream processing performance of a mineral ore is critical to resource evaluation and development decisions, where significant cost and productivity benefits can be realized through early determination of an ore’s properties and processing potential. This study aimed at investigating the chemical, qualitative and quantitative composition of raw iron ore from the deposits in Katse area (Mwingi North Constituency in Kitui County) which lies in the Mozambique mobile belt. The quality of the iron ore was evaluated to establish its suitability as a raw material for iron production in Kenya. Samples were obtained along the perimeter vertices and centre of a land parcel measuring 150m2 with each excavation being 50cm length, 50 cm width and 500cm depth. Detailed studies were conducted to establish the composition and properties of the 5 samples. X-ray Diffraction (XRD), X-ray Fluorescence (XRF) and Atomic Absorption Spectrometry (AAS) techniques were employed in the investigation. XRD studies revealed magnetite (above 86%) as the major mineral with subordinate amounts of hematite and quartz. XRF studies indicated a high content of iron (above 80%) with minor amounts of (5% Al2O3, < 5%TiO2, 1-44% SiO2, <1% of MnO, P2O5, SO3, K2O, V2O5). AAS experiment results indicated that the Iron content was above 90% with minor amounts of SiO2, Al2O3, CaO, MgO, Na2O, K2O, TiO2 and MnO elements. The quality of this ore was compared to generalized world market standards and ores from other nations. The results indicated that Katse ore is a rich Magnetite grade with Fe content above 80% with minor amounts of hematite, quartz and clay as the major gangue (<1% SiO2 and <1% Al2O3) and low contents of the deleterious elements ( <1 %), which correspond to acceptable levels for commercial iron ores.
