The Properties of Sisal Fibre and Sisal Fibre Reinforced Composite Materials
(1979)The effect of chemical treatment on the tensile properties of sisal fibre-reinforced LDPE (low density polyethylene) composites was investigated. Treatments using chemicals such as sodium hydroxide, isocyanate, permanganate ... -
The Potential of Sisal as a reinforcing Fibre in Cement base materials
(1982)The inclusion of fibre reinforcement in concrete, mortar and cement paste can enhance many of the engineering properties of the basic materials, such as fracture toughness, flexural strength and resistance to fatigue, ... -
"Universal SCFs and Optimal Chamfering in Cross - bored Cylinder
(2006)A three-dimensional finite element computer program was developed to establish the stress distributions and stress concentration factors (SCFs) in chamfered cross-bored cylinders under internal pressure. The displacement ... -
The African charcoal Stove: It
(1985)Over 125,000 fuel-efficient, ceramic-lined charcoal stoves for household cooking have been disseminated in Kenya. This program has been relatively successful because (1) it was built on the design of the traditional stove ... -
A cost Effective Method of Ethanol fumigation is small Diesel Engines
(1993)To diversify the mix of domestic energy resources and to reduce dependence on imported oil, ethanol is widely investigated for applying in combination with Diesel fuel to reduce pollutants, including smoke and NOx. Present ... -
Use of ethanol in Diesel Engines:
(1993)Two organic additives were selected for their different physico-chemical parameters to study the behaviour of a diesel–ethanol mixture. These compounds had a glycerol skeleton bearing heteroatoms and amino-ether, hydroxyl, ... -
Ethanol Fuel substitution Through Fumigation
(1996)The effects of ethanol fumigation (i.e. the addition of ethanol to the intake air manifold) and ethanol–diesel fuel blends on the performance and emissions of a single cylinder diesel engine have been investigated ... -
Local Development of a Production Process for Replacement Cylinder Head
(2001)Several constraints exist in the local market as regards the purchase and after - sales services of small stationary diesel engines used for flour milling, water pumping and generation of electricity. These constraints ... -
Small scale manufacture of replacement crankshaft
(2002)Local production of spares has been recognised to have direct economic advantage for the national economy in which the equipment operates. The crankshaft of a single cylinder diesel engine for which the approximate cost ... -
Rural-Urban Relations, Household Income Diversification and Agricultural Productivity
(1991)Does rising income from agriculture drive the growth of nonfarm activities, or does increased income from nonfarm activities spur the growth of agriculture? This paper looks at the role of nonfarm income in enabling ... -
Transportation and Characteristics of Urban Travel in Nairobi:
(1992)Market access measures employed by economists and spatial analysts may not adequately capture local market or product-specific variation. Analysis is conducted on the effects of market access on two commodities in the ... -
Rural/Urban Linkages in Kenya and Zimbabwe: A Comparative Perspective
(1997)Sub-Saharan Africa is steadily becoming less rural in character. For decades development thinking has prescribed industrialization as the virtuous path leading away from economic dependence on agriculture. But Africa's ... -
Regional Development Profile of Ewaso Ng
(1999)Water resources are becoming increasingly scarce in the Mt. Kenya region. Land use and climate change may pose additional challenges to water management in the future. In order to assess the impacts of environmental change, ... -
Potential for solar energy utilisation in the West Indies. 'Description of solar energy R & D programs in many nations
(1976)This paper is a review of worldwide direct applications of geothermal energy. It attempts to update the surveys presented at and after the World Geothermal Congresses of 1995, 2000 and 2005. Seventy-two countries report ... -
Transient flow development due to a strong heat source in the atmosphere; Part I:
(1980)This paper describes a finite difference experiment to simulate the transient development of the convection column above a strip of uniform high temperature source in a stratified uniform cross flow atmosphere. The κ-ε ... -
Some characteristics of a two-dimensional starting mass fire with cross flow
(1981)A numerical model which can be used to study some aspects of mass fires is presented. The k—ϵ model of turbulence and the flame sheet model of combustion are employed. To account for the “unmixed-ness” of the fuel and ... -
Experimental modelling of axial temperature profiles of buoyant diffusion flames
(1987)Mean temperatures were measured along the axis of propane gas flames using a porous ceramic burner. Data for fire heat release rates ranging form 13.3kW to 30.6kW were taken and analyzed. It was found that the lower zone ... -
An experimental study of the multipass operation of double-glazed solar air heaters
(1991)Solar air heating (solar collector) is a renewable heating technology and provides heat using solar energy. With fuel costs and other factors, solar air heaters (SAHs) are getting more attention. The energetic and exergetic ... -
Numerical Modelling of Aerodynamic Performance of Aerofoil Windmill Blades at Various Blade Configurations
(1995)Abstract The accurate prediction of the aerodynamics and performance of vertical-axis wind turbines is essential if their design is to be improved but poses a significant challenge to numerical simulation tools. The ... -
Quality Assurance and Relevance of Engineering Education in Africa
(1997)Economic development is correlated with the development of higher education: enrollment ratios in higher education average over fifty percent for countries belonging to the Organization for Economic Cooperation and ...
