The dislocation core misfit potential
(University of Nairobi, 2015)The development of a model to extend the range of the embedded atom method (EAM) is presented. The model is founded on the premise that the dislocation core generates a distortion field within the lattice that extends well ... -
Chapter 6 – remote sensing application supporting IWRM in Kenya
(University of Nairobi, 2013)This chapter begins with a synopsis of the basic concept of remote sensing with the various stages and interactions that characterize the entire remote sensing process described. A brief recapitulation of the status of ... -
Stabilization of solid waste through leachate recycling
(University of Nairobi, 1994)One characteristic which landfills Have in common is the long stabilization times they require. Stabilization implies that conditions within the fill have achieved a state of relative physical, biological and chemical ... -
Impact of Land Use /Cover dynamics on Streamflow: A Case of Nzoia River Catchment, Kenya
(University of Nairobi, 2010)Degradation of watershed areas in Kenya’s basins is on the increase and is currently a major concern for the government. The main causes of watershe d degradation stem from the abuse and poor management of forests ... -
Review of soil water retention characteristic (SWRC) models between saturation and oven dryness
(University of Nairobi, 2014)Soil water retention characteristic is the key soil property used in many applications in the fields of irrigation, hydrology, geotechnical engineering and soil science in general. Since the advent of digital soil mapping ... -
Assessing the Impact of Rainwater Harvesting Technology as Adaptation Strategy for Rural Communities in Makueni County, Kenya
(2014)Rainfall scarcity is a constraint to productivity in arid and semiarid regions of Kenya. This chapter identifies the common rainwater harvesting technologies used in Makueni County, a semiarid region, both for domestic and ... -
Tectonic structures across the East African rift likely to pose the greatest earthquake hazard in Kenya.
(University of Nairobi, 2012)Over the last 5-10 years, there has been accelerated geothermal resources development for geothermal power generation in order to meet the country’s electricity demands and hence make Vision 2030 feasible. However, owing ... -
Identification of groundwater potential zones using remote sensing and GIS in lake Chala watershed, Kenya
(University of Nairobi, 2013)Groundwater is a natural resource of the earth that sustains and supports domestic, agricultural and industrial activities. It is distributed fairly and evenly throughout the world and over half of the world’s population ... -
The effect of strain rate and specimen length on the stress-strain relationship of vegetation roots used in slope stabilization.
(University of Nairobi, 2015)The main objective of this investigation was to provide information about the contribution of plant roots to soil shear strength. Reconnaissance of the case study areas was undertaken and geology of the areas established, ... -
Effect of heat on mechanical properties and microstructure of reinforcing steel bars made from scrap
(University of Nairobi, 2014)Mechanical properties of reinforcing steel bars (rebars) degrade with elevated temperatures and this deterioration has to be properly accounted for to understand the behaviour of rebars and composite structures in fire. ... -
Application of gis to water quality management for the city of Nairobi water supply.
(University of Nairobi, 2014) -
Polydisperse Low Diameter ‘Non-Toxic’ Silver Nanoparticles Encapsulated by Rooibos Tea Templates
(University of Nairobi, 2014)This work reports the synthesis of ‘non-toxic’ polydisperse, low diameter silver nanoparticles (AgNPs). Rooibos extracts at temperatures 25 °C, 30 °C, 50 °C, 70 °C and 90 °C were used. The effect of different extraction ... -
Development of vVC-NI eutectic alloys for wear resistance
(University of Nairobi, 2014)Vanadium carbide is less dense, harder and tougher than tungsten carbide, and nickel is more corrosion resistant that cobalt. Replacing the binder with Ni should improve the corrosion resistance. Since there are eutectics ... -
Development of an x-ray method for mineralogical analysis of Africa soils using a benchtop diffractometer
(University of Nairobi, 2014)Soil mineralogy is a principal determinant of many soil functional properties that are expensive and time consuming to measure, and can in turn determine soil agricultural, engineering and environmental qualities. ...
