(201)This paper reports on the study that investigated the following question: How do Kenyan science teachers perceive the impact of students’ contextualized science learning on their pedagogy, roles and Views about previously ... -
Assessing conservation agricultural production systems (caps) for small holder farmers in rain-fed farming system in sub-saharan Africa (ssa)
(2012)The challenge of sufficient food production by farmers in rainfed farming systems of sub-Saharan Africa is exacerbated by soil degradation and poor soil nutrient status. The objective of this study was to assess the effects ... -
Conservation agriculture for smallholder farms in eastern Uganda and western Kenya
(2012)Soil quality and crop yield parameters resulting from conservation agriculture practices were evaluated in on-station and on-farm studies established in two highland sites and two lowland sites in the Mount Elgon region ... -

(2017)The purpose of this study was to assess the challenges facing the society specifically the farmers and the country on the growing popularity of the green maize harvesting within the growing areas. The study was geared ... -
Conservation agriculture effects on earthworm populations in western Kenya and eastern Uganda soils.
(RUFORUM, 2014-07-25)Conventional cultivation in Western Kenya and Eastern Uganda over the years has resulted into decline in soil quality and food crop production. Studying soil biodiversity under Conservation Agriculture production systems ... -
Heavy metal distribution in soils of some urban and peri-urban horticultural farms in Botswana
(RUFORUM, 2014-07)Despite the fact that there is high usage of agrochemicals and use of urban waste water for irrigation, the concentration of potentially toxic metals in urban and peri-urban agriculture (UPA) farms has not been widely ... -
Derivation and solution of the heat equation in 1-D
(International journal of engineering, science and mathematics, 2013)Heat flows in the direction of decreasing temperature, that is, from hot to cool. In this paper we derive the heat equation and consider the flow of heat along a metal rod. The rod allows us to consider the temperature, ... -
Forensic estimation of time of death: A mathematical model
(International journal of management, IT and engineering, 2013)In this paper we establish the exact time of death of a murdered person. This leads to an ordinary differential equations whose solution has been analyzed to provide the approximate time of death. Forensic expert will ... -
The role of teachers in implementing effective play in early childhood and educational centers
(Lap lambert academic publishing, 2013)Over the last several years, there has been an increased focus on school readiness and supporting children during the preschool years to learn the skills they need to be successful in elementary school and beyond (Bowman, ... -

Mathematical modeling of insulin therapy in patients with diabetes mellitus
(IJESM, 2015)—This study presents a Mathematical Model Insulin Therapy in Patients with Diabetes Mellitus which includes external rate at which blood glucose, insulin and epinephrine are being increased in the form, Y =AY+r (t) ... -
Mathematical modelling of the role of interference on the transmission dynamics and management of Hiv and Aids
(2018-09-22)In this paper, a deterministic mathematical model incorporating interference is developed andanalysed to investigate the role of interference on the transmission dynamics and managementof HIV and AIDS. The model is shown ... -
Mathematical model for detecting diabetes in the blood
(Journal of applied mathematical sciences, 2011)This study presents a new mathematical model for Blood Glucose Regulatory System(BGRS) which includes epinephrine as a third variable in the form, Y˙ = AY, and whose solution has been analyzed for equilibrium and stability ... -
The use of phytochemical composition of fifty (50) selected plants found in the university botanic garden, Maseno, Kenya to show
(2015-08-02)Qualitative phytochemical analysis of 50 plants, five each from 10 selected families is presented. The ten plant families were selected based on their high plant frequency of occurrence within the botanic garden. The powdered ... -
Effects of fresh leaf materials of sesbania sesban (l.) merrill on the growth and photosynthetic pigments of nightshade (solanum nigrum l. var. popolo)
(INNSPUB, 2014-05-15)Solanum nigrum L. is one of the African leafy vegetable consumed in Kenya. High cost of inorganic fertilizers has made it inaccessible by smallholder farmers leading to low yields. A study was conducted at Maseno ... -
Responses of slenderleaf rattlebox (crotalaria ochroleuca) to water deficit
(2017)Water deficit affects plant growth and development thus affecting crop productivity. It is the major a biotic stress experienced in the vast semi arid and arid regions of Kenya and the world as a whole. Water deficit mainly ... -
A Predator-Prey Model with a Time Lag in the Migration
(2014)We develop a two-patch migration model of the classical LotkaVoltera predator-prey system with a time lag in the migration between patches. We show that when the migration rate is less than the prey growth rate the species ... -
