Micronutrients in selected food crops in Muguga, Kenya
(University of Nairobi, 2014)
Micronutrients are essential for growth of
plants and although they are required in
small quantities, inadequate supply of one
or more of these results in reduced yields
and quality of crop products. Micronutrients
are ...
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 ...
Towards Plane Hurwitz Numbers
(University of Nairobi, 2014)
The main objects of this thesis are branched coverings obtained as projection from a point in P^2. Our general goal is to understand how a given meromorphic function f: X -> P^1 can be induced from a composition X --> C ...
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. ...
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 ...
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. ...
Camel milk hygiene

First Total Reflection X-ray Fluorescence Round-robin Test Of Water Samples: Preliminary Results
(University of Nairobi, 2014)
otal Reflection X-Ray Fluorescence (TXRF) is a mature technique to evaluate quantitatively the elemental composition of liquid samples deposited on clean and well polished reflectors. In this paper the results of the first ...
East Africa’s dangerous dance with the past: important lessons the new East African community has not learned from the defunct
(University of Nairobi, 2014)
This paper argues that while the framers of the new East African Community, cognizant of the problems of the defunct one, set out to create a new organization that would avoid the pitfalls of the old they were not bold ...
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 ...
