Biosorption of heavy metals using water hyacinth Eichhornia crassipes (Mart.) solms-Laubach: adsorption properties and technological assessment
(University of Nairobi, Kenya, 2011)
The adsorption of heavy metal ions (Cd2+), Cu2+), Pb2+) and Zn2+) by untreated water hyacinth Eichhornia crassipes obtained from Lake Victoria, Kenya was investigated under batch mode. A The effects of sample part, particle ...
Th e role of wild host plants in the abundance of lepidopteran stem borers along altitudinal gradient in Kenya
(2006)
Presence of wild host plants of stem borers in cereal-growing areas has been considered
as reservoirs of lepidopteran stem borers, responsible for attack of crops during the growing season.
Surveys to catalogue hosts and ...
Applications of mathematics in social and biological sciences
(2012)
The infinte and elegant universe has inspired wise-men in
societies to formulate and develop mathematical concepts
throughout history. It has served survival needs, been used in

Study of non-normal operators in a complex Hilbert space
(2008)
This paper is on some special characteristics of non-normal operators.
We first seek to show that if a bounded operator Tis paranormal: what about Tl? Here its enough to find aTE 8(H) for which Tl is not hyponormal but ...
Stability Investigation in the Optical Properties of Thermally Evaporated Ge5Se95-x Znx Thin Films
(University of Nairobi, 2015)
Selenium-based chalcogenides are useful in telecommunication devices like infrared optics and threshold switching devices. The investigated system of Ge5Se95-xZnx (0.0 ≤ x ≤ 4 at.%) has been prepared from high purity ...

The human immunodeficiency virus (HIV), the virus that causes the acquired immune deficiency syndrome (AIDS) has for many years devastated lives and still continues to do so in the present day. Reducing the spread of ...
Covariance differences of linealy representable sequences in Hilbert spaces
(2006)
The paper introduces the concepts of covariance differences of a sequence and establishes its relationship with the covariance function. One of the main results of this paper is the criteria of linear represent-ability of ...
Molecular characterization and identification of biocontrol isolates of Trichoderma harzianum from Embu district, Kenya
