Implications of the European Market on Africa Economies and the Emergence of a United States of Africa
(1995)
For a capatalist economy to function, its labor force must be maintained; that is, workers must receive a historically determined minimal day-to-day subsistence. It must also be renewed; that is, vacancies must be filled. ...
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 ...
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 ...
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 ...
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, ...
Estimation of Infiltration Parameters at the Steepland Research Station, Kabete, Nairobi, Kenya
(1997)
This study proposes a method for the estimation of lag time of forested mountainous watersheds. Hydrological flood-flow design methods require a time parameter, such as lag time or time of concentration, to estimate peak ...
Sulfide Toxicity in Anaerobic Systems Fed Sulfate and Various Organics.
(1993)
Upflow anaerobic filters fed acetate and propionate, and completely mixed, suspended growth reactors fed acetate, propionate, lactate, and glucose were used to investigate the effect of electron donor and reactor type on ...
"Energy and Air Quality Assessment in Transport Industry in Kenya
(1999)
We examine the links between fossil-fuel-based transportation, greenhouse-gas emissions, and health. Transport-related carbon emissions are rising and there is increasing consensus that the growth in motorised land vehicles ...
Finite-element analysis of non-uniform, lossy transmission lines
(1997)
This paper presents an overview of the transmission-line matrix (TLM) method of analysis, describing its historical background from Huygens's principle to modem computer formulations. The basic algorithm for simulating ...
Water and Sanitation Services in Low Income Areas of Nairobi
(1994)
This paper provides an overview of the state of municipal solid waste management (MSWM) by local authorities in Kenya as a case study of a low-income developing country. Approaches of possible solutions that can be undertaken ...
