(University of Nairobi, 2017)
Knockdown efficacy of commercial aerosol insecticides against laboratory reared Anopheles gambiae
Kisumu strain mosquitoes and suppression of indoor resting density of A. gambiae complex mosquitoes in the
field were ...
Expressed Centromere Specific Histone 3 (CENH3) Variants in Cultivated Triploid and Wild Diploid Bananas (Musa spp.).
(2017-06-29)
Centromeres are specified by a centromere specific histone 3 (CENH3) protein, which exists in a complex environment, interacting with conserved proteins and rapidly evolving satellite DNA sequences. The interactions may ...
The Working Group on the Anthropocene: Summary of evidence and interim recommendations
(University of Nairobi, 2017)
Since 2009, the Working Group on the ‘Anthropocene’ (or, commonly, AWG for Anthropocene Working Group), has been critically analysing the case for formalization of this proposed but still informal geological time unit. The ...
On Local Linear Regression Estimation In Sampling Surveys
(2017-10)
A model-based survey is employed to estimate the unknown values of the survey variable, using the local linear regression approach. In particular, a local linear regression estimator in model-based surveys is studied. ...
Pyrazole, isoxazoline and bypyrimidine derivatives from polygonum senegalense and psiadia punctulata flavonoids and their anti- microbial activities
(University of Nairobi, 2017)
Currently, researchers have given special attention to the synthesis of hetero
cyclic compounds with nitrogen and oxygen five in five or six
membered
ring systems. This is mainly due to their wide range of biological ...
Semi-synthetic pyrazoline derivatives from polygonum senegalense chalcones and their anti-microbial activities
(University of Nairobi, 2017)
This paper describes the semi-synthesis and anti-microbial activity of novel
pyrazoline derivatives of
Polygonum senegalense
chalcones. The study
was carried out on the understanding that heterocycles ...
Use of intelligent agents in collaborative m-learning: case of facilitating group learner interactions
(University of Nairobi, 2017)
Intelligent agents have been used in
collaborative learning. However, they are rarely used to
facilitate group interactions in collaborative m-learning
environments. In view of this, the paper discusses the use
of ...
Field evaluation of resistance to aflatoxin accumulation in maize inbred lines in Kenya and South Africa
(University of Nairobi, 2017)
Aflatoxin, a carcinogenic toxin, is produced mainly by Aspergillus flavus and Aspergillus parasiticus. Contamination of maize (Zea mays L.) grain by these fungi occurs before harvest, and the easiest strategy to prevent ...
Susceptibility of locally cultivated groundnut (Arachis hypogaea) varieties to aflatoxin accumulation in Homa Bay County, Kenya
(University of Nairobi, 2017)
Groundnut is one of the staple foods in many parts of the world. Due to its high nutrient content, the
nuts are liable to colonization by aflatoxigenic fungi and subsequent aflatoxin accumulation. This study
was aimed ...
Mycoflora and mycotoxins in finished fish feed and feed ingredients from smallholder farms in East Africa
(University of Nairobi, 2017)
A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in
Kenya, Tanzania, Rwanda and Uganda, and analyzed. Culture and molecular techniques were used to
identify fungal ...
