(University of Eldoret, 2018)This thesis deals with the solution of the non-linear third order partial differential equation of a steady hydromagnetic laminar flow of a conducting viscous incompressible fluid through a channel with two parallel ... -
SOLVING MATHEMATICAL WORD PROBLEMS IN SECONDARY SCHOOLS: A CASE OF TINDERET SUB-COUNTY, NANDI COUNTY KENYA
(University of Eldoret, 2020)Mathematical word problems are concepts taught at the end of every topic to allow students apply the content that was taught. The study focused on investigating the student’s difficulties in solving mathematical word ... -
SOME NEW SECOND ORDER ROTATABLE DESIGNS BASED ON BALANCED INCOMPLETE BLOCK DESIGN
(University of Eldoret, 2014)The purpose of this study was to construct some new second order rotatable designs using balanced incomplete block designs. The study of rotatable designs is mainly concerned with the estimation of absolute response in ... -
THE SPATIAL AND TEMPORAL VARIATION OF SELECTED HEAVY METALS, NITROGEN AND PHOSPHORUS IN WATER AND SOILS OF YALA SWAMP, KENYA
(University of Eldoret, 2013)Studies involving pollutants in the environment have been used as an indicator of their accumulation resulting from human activities. A study of spatial and temporal variation of pollutants involving forty four water and ... -
SPATIAL AND TEMPORAL VARIATIONS IN PHYSICO-CHEMICAL
(2016-05-19)Increased human activities have led to water pollution, especially metals and nutrients. Therefore, prudent management of aquatic environments require information on their quality status that can be estimated by monitoring ... -
SPATIAL AND TEMPORAL VARIATIONS IN PHYSICO-CHEMICAL PARAMETERS, NUTRIENTS AND HEAVY METALS ALONG A GRADIENT OF ANTHROPOGENIC ACTIVITIES WITHIN KAPSABET RIVER, KENYA
(University of Eldoret, 2013)Increased human activities have led to water pollution, especially metals and nutrients. Therefore, prudent management of aquatic environments require information on their quality status that can be estimated by monitoring ... -
Spatial and TemporalVariability of Phosphates, Nitrates and Selected Physico-Chemical Parameters of River Nzoia
(Africa Environmental Review, 2022)Several agricultural activities are practiced within the River Nzoiacatchment area, most of which involve application of chemicals in form of fertilisers and pesticides.Most of these chemicals end up in the ... -
