Partial Replacement Of Natural River Sand With Crushed Rock Sand In Concrete Production
(University of Nairobi,, 2013)The use of crushed rock sand as a partial replacement of river sand in concrete production was investigated. Water cement ratio varied between 0.55 and 0.59 for 0 % to 100 % natural sand replacement. The slump ranged ... -
Micromechanisms of short fatigue crack growth in an Al-Si piston alloy
(University of Nairobi, 2014-06)The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue ... -
Environmental Impact Assessment in Kenya
(University of Nairobi, 2013)In Kenya, environmental impact assessment (EIA) has been used to ensure that environmental management is integrated into project planning and decision-making with a view of achieving ecologically sustainable development. ... -
The production of artisanal dimension stone in Nairobi: A factor analytic study
(University of Nairobi, 2013)The study looked at the opportunities and constraints facing artisanal units involved in the production of dimension stone. Twenty-seven observable variables were derived from literature and developed into a questionnaire ... -
Application of artisanal dimension stone in the building industry: factor analysis of the regulatory environment in Nairobi, Kenya
(University of Nairobi, 2014)This is an assessment of the regulatory environment in which artisans operate to produce dimension stone in Nairobi where the quarrying of the same becomes an aspect of artisanal mining; an activity that is fraught with ... -
University–industry partnership for effective industrialization: a framework for Ngumzo
(University of Nairobi, 2002)A conceptual framework for partnerships between University and Industry emphasizing the need for Ngumzo (i.e. dialogue with harmony) is presented. This framework is based on the model of a microprocessor. Inputs that ... -
On the Performance of Video Band Complex Correlators
(University of Nairobi, 1983-05-19)The performance data for various correlation schemes for Gaussian signals converted from the intermediate frequency band to the video band are derived and discussed. The folded-band conversion scheme is shown to have ... -
Correlation Systems In Radio Astronomy And Related Fields
(University of Nairobi, 1984-02)A comprehensive review of the theory and practice of analogue and digital correlation systems used in radio astronomy and its related fields is given. The correlators are discussed according to the following classifications: ... -
Long baseline determination using observations with macrometer II prototype receivers.
(University of Nairobi, 1987) -
Rectangular-Wave Modulation
(University of Nairobi, 1983-03)Rectangular-wave modulated pulse lengths are expressed as a function of the modulation index. The theoretical expressions are experimentally verified. An experimental measurement of signal-to-noise ratio for rectangular-wave ... -
Error Patterns In Correlators With Four-Level Quantisation
(University of Nairobi, 1984-02)In the evaluation of the analogue correlation from the digital correlation of coarsely quantised Gaussian signals, it is necessary to know the threshold levels used in the quantisation. The formulas used in the evaluation ... -
Properties of crude oil from indigenous oilseeds in Africa.
(University of Nairobi., 1999)Properties of crude oil from 4 indigenous oilseeds (Calodendrum capense, Croton megalocarpus, Podocarpus gracilior, and Pittosporum viridiflorum) in Africa (Kenya) were determined and their potential use as fuel, lubricants, ... -
Economic Performance Comparison Of Combined-cycle And Cogeneration Proposals For Pipeline Application
(University of Nairobi, 1996-10)Gas/steam turbine combined-cycle and cogeneration plants embrace the total energy concept which seeks to utilize to the maximum the energy available in a system. The technology used for a given duty depends partly on the ... -
Cogeneration In Rural Development
(University of Nairobi, 1995-02)The excellent thermodynamic performance offered by cogeneration plants indicates that cogeneration is an attractive means of meeting the energy needs of industry and that it can contribute significantly to the efficient ... -
