Potato (Solanum tuberosum L.) is the fourth most important food crop in the world after rice, wheat, and maize. Potato plays a significant role in human nutrition worldwide, where more than 320 million tons of potato is ...

Due to the increasing price, demand, consumption of cement, and environmental impacts of solid waste build up, researchers and scientists are in search of developing alternatives to aggregates and binders, which are cheaper, ...

Ruiru reservoir is one of the main source of water supply to Nairobi City and its environs. During the wet season, the reservoir overspills. Meanwhile, the water demand keeps increasing every year in Nairobi city due to ...

Rosa rubiginosa is popular in Lesotho where rural communities sell the rosehips to the local companies. However its deep seed dormancy and absence of a regeneration protocol presents a challenge in establishing its plantations ...

In real life situations, the values of the response variable, which is the count data is mostly under-reported. In this work, we develop a model to cater for under-reporting in count data. In particular, we allow ...

Financial crisis of 2007-2008 changed the assumptions underlying market models theoretically and in practice. Therefore, this research focuses on modelling the impact of interest rate financial crisis. The aim was to ...

In this study, we investigate the flow in an open rectangular channel with a lateral inflow channel. The flow of an incompressible Newtonian fluid through a man-made open rectangular channel with a lateral inflow channel ...

This thesis presents estimation of panel data regression models with individual effects. We discuss estimation techniques for both fixed and random effects panel data regression models. We derive two-stage least squares ...

In this study, the problem of nonparametric estimation of finite population total using multiplicative bias correction technique is considered. A review of the model-based, design-based, model-assisted, randomization-assisted ...

In this study, the turbulent fluid flow problem of a conducting fluid past an infinite porous vertical plate in a rotating system is investigated. Hall currents, mass transfer and Joule’s heating are accounted for in the ...
