On Modelling and Pricing Rainfall Derivatives with Seasonality
(2011)
We are interested in pricing rainfall options written on precipitation at specific
locations. We assume the existence of a tradeable financial instrument in the market whose price
process is affected by the quantity of ...
Taxis assays measure directional movement of mosquitoes to olfactory cues
(2013)
Background
Malaria control methods targeting indoor-biting mosquitoes have limited impact on vectors that feed and rest outdoors. Exploiting mosquito olfactory behaviour to reduce blood-feeding outdoors might be a ...
Biosorption of Malachite Green from Aqueous Solutions onto Polylactide/Spent Brewery Grains Films: Kinetic and Equilibrium Studies
(2012)
Batch experiments were conducted to study the biosorption of Malachite Green (MG) onto polylactide (PLA)/spent brewery grains (SBGs) films. Films were prepared by solvent-casting method using dichloromethane. Effects of ...
The effect of Temperature and blending on the specific gravity and viscosity of Jatropha Methyl ester
(2011)
The specific gravity and viscosity of biodiesel fuels are key properties in determining the suitability for use of such fuels in diesel engines. Though generally higher than those of #2 diesel fuel (DF2), they have been ...
Identification Of Candidate Volatiles That Affect The Behavioural Response Of The Malaria Mosquito Anopheles Gambiae Sensu Stricto To An Active Kairomone Blend: Laboratory And Semi-field Assays
(University of Nairobi, 2012)
Anopheles gambiae Giles sensu stricto (Diptera: Culicidae) is the most important vector of human malaria in sub-Saharan Africa, affecting the lives of millions of people. Existing tools such as insecticide-treated nets and ...
Changes in temperature and precipitation extremes over the Greater Horn of Africa region from 1961 to 2010
(University of Nairobi, 2013)
Recent special reports on climate extremes have shown evidences of changes in the patterns of climate extremes at global, regional and local scales. Understanding the characteristics of climate extremes at regional and ...
Environmental variability in Lake Naivasha, Kenya, over the last two centuries
(2011)
Lake Naivasha, Kenya, is one of a number of freshwater lakes in the East African Rift System. Since the beginning of the twentieth century, it has experienced greater anthropogenic influence as a result of increasingly ...
