Effects of use of latex rubber gloves by dental students at the dental school, faculty of dental sciences
(University of Nairobi, 2008)
Introduction: Latex is the material that rubber gloves are made of. The powder inside gloves and even the latex itself may elicit a latex reaction on the handler of the gloves or the patient. Latex reactions have become ...
Discussion of a food and nutrition policy for Kenya
(1974)
The paper was produced on request of the Head of the Kenya Delegation to the 1974 World Food Conference in Rome. It reflects the authors’ views on basic policies to improve the nutritional status of vulnerable groups in ...
A model based on reaction kinetics and elemental diffusion is proposed to account for the presence of double inflection in the hardness profiles of the heat-affected zone (HAZ) in weldments of AI-Li-X alloys tested without postweld heat treatment (PWHT). Such profiles are particularly evident when 1 ) the base metal is in the peak-aged (T8 or T6) temper condition prior to welding; 2) the welding process is a high-heat input process, i.e., gas tungsten arc (GTA), gas metal arc (GMA) or plasma arc (PA) welding; and 3) a filler alloy deficient in lithium (i.e., AA 2319)is used. In the first part of this paper, the theoretical mechanisms are presented. It is proposed that the double inflection appears due to complete or partial reversion of the semi-coherent, plate-like precipitates (i.e., 0% T 1 or S'); coarsening of the platelike precipitates at constant volume fraction; precipitation of ~5' as a result of natural aging; and diffusion of lithium from the HAZ into the weld pool due to the concentration gradient between the weld pool and the base metal. In the second part (to be published in next month's Welding Journal), experimental validation of the model is provided using weldments of the AI-Li-Cu Alloy 2095.

Balancing work and study A necessity for successful Distance Learning
(University of Nairobi, 2015-07-19)
As the country re- evaluates the achievement of Millennium goals, it becomes important for Kenya to take its toll. One of the intentions was to increase gross enrolment rate in higher education. The projection was to ...
A multilevel analysis of prenatal care and birth weight
(University of Nairobi, 2012)
The paper investigates the effect of adequate use of prenatal care on birth weight in Kenya using data from the Kenya Demographic and Health Survey of 2008–2009 together with additional administrative data. Both a single–level ...
