Potential for ground charcoal for synthetic dye removal
(Department of Civil & Construction Engineering, University of Nairobi,, 2003)The potential for ground charcoal for synthetic dye removal was investigated in a series of batch experiments. Ground charcoal from black wattle tree was used to remove a synthetic dye, Congo red from water through ... -
Pollutional effect of brewery waste water on Ruiruaka river
(Department of environmental and biosystems engineering, 1992)The rapid rate of industrial and urban growth in Kenya with the resultant pollution of aquatic systems provided stimulus to the present study on the pollutional effects of brewery effluent on Ruiruaka river.The river, ... -
Studies on mechanical properties and microstructure of gravity die cast grey irons
(1996)The influence of some process variables like casting size, initial mould temperature, mould wall thickness, inoculation and composition on microstructure, hardness and tensile strength of gravity die cast grey irons were ... -
Evaluation of performance of iron removal plants for groundwater treatment in western Kenya
(Department of Civil and Construction Engineering Building, 1994)Iron is an important constituent in industrial process and drinking water. However, the presence of Iron in excessive concentrations makes the water objectionable for drinking and other industrial applications. Techniques ... -
Algae removal from effluents of waste water stabilization ponds utilizing intermittent sand filtration
(Department of Civil Engineering, University of Nairobi, 1992-06)The principle objective of this research was the removal of algae from effluents of waste water stabilization ponds. There are many possible ways of achieving this removal but problems such as of economics, technological ... -
Urban solid waste management system using Geographic Information Systems (GIS): A case study of Kayole - Soweto, Nairobi.
(Department of Arts, 2005)The problem of solid waste is prevalent in Nairobi city in general, and is most acute in the low-income residential estates. It is mainly manifested in form of littering and illegal dumping in areas not designated for ... -
The effect' of chamfer angle and size on the stress distributions and stress concentration faci'ors in thick walled cylinders with cross bores under internal pressure
(Department of Mechanical Engineering, 1995)The stress distributions in a closed ended thick walled cylinder with a chamfered cross bore under internal pressure were investigated. Attention was paid to the region forming the surface of the cross bore. The finite ... -
On of rectangular and circular plates: the effect of a concentrated mass.
(Department of Mechanical Engineering, 1993)The problem of vibration of plates loaded with a concentrated mass has not been extensively studied. In this study therefore, the free vibration and harmonically forced vibration of rectangular and ... -
Photogrammetric densification of ground control
(1989)In many types of surveys, it is essential to have ground control points. These are points on the ground whose coordinates are known in a ground system to a certain standard of accuracy . . A situation arises when the ... -
Characteristics of some Kenyan sands and their effect on mortar strength
(Department of Civil Engineering, 1992)In Kenya, portland cement (Ordinary and Rapid-hardening) strength quality control is done to meet the requirements of the British standard BS 12: 1989 or the ... -
Structural strength and performance of cement - stabilized murram blockwalls
(Department of Civil Engineering, 1992)The thesis gives figures by the Central Bureau of Statistics showing that for a reasonably decent residential house,wall construction materials account for 25% of the total cost of materials. It therefore concludes that ... -
The interaction of universities and industry in science
(1996)There is an emerging consensus in the literature that increased university-industry interactions are not only possible, but also desirable. The awareness of the importance of the university-industry interaction phenomenon ... -
Optimization of power plant dispatch and capacity expansion in Kenya
(Department of environmental and biosystems engineering, 2008)The need to study the Kenyan national power system with a VIew to minimising environmental emissions and energy production costs in the present and the long-term was identified. The overall objective ... -
Performance of local sands in mortar for cement quality control
(University of NairobiDepartment of Civil Engineering, 1995)Standard sand plays a most important role in the cement industry. Not only is it used to asses the quality of cement but it is also required as a standard material to study the properties of other building materials e. ... -
The effect of inorganic salts on the gasification of biomass in a fluidized bed
(Department of ChemicalEngineering, 1993)The effects of inorganic salts on the yields and distribution of products from air gasificationof biomass in a fluidized bed were investigated. The main objective was to establishconditions for production of ... -
Theoretical and experimental analysis of solar multi-pass air solar heaters
(Department of Mechanical Engineering, 1990)Expressions for the performance of Solar air heaters operating in four modes were derived and solved using a computer and the results from a series ... -
Ageing of bitumen in tropical conditions
(Department of Civil Engineering, 1992)The flexibility of asphaltic pavements diminishes as the bitumen binder ages. Consequently, surfacing failure occurs by cracking and disintegration under traffic ... -
Incompressible aerodynamiic performance of aerofoil blades of various configurations
(Department of Mechanical Engineering, 1993)Plow over can~ered aerofoils with thickness to chord ratios of 10.82%,12.99%,16.24%, and 18.5690 were numerically modelled using k-w method for boundary layer flows. The aerofoils were of 5?o, 6% and 7% camber ... -
Horizontal tube-side condensation of steam in the presence' of a non-condensable gas.
