Codon bias of influenza a viruses and their hosts
(Scientific Research Publishing, 2011-10)The Influenza A virus remains an annual and worldwide health concern due to its fast evolutionary rate. There are two major forms of Influenza evolution: drift, caused by mutations, and shift, which results from the exchange ... -
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ... -

Coffee Breeding in Kenya: Achievements, Challenges and Current Focus
(2015)Coffee production in Kenya is seriously constrained by two fungal diseases namely Coffee Berry Disease (CBD) caused by Colletotrichum kahawae (Waller & Bridge) and Coffee Leaf Rust (CLR) caused by Hemileia vastatrix (Berk. ... -
Coffee Drying in a Rotary Conduction-Type Heating Unit
(Blackwell Publishing Ltd, 2004-06-01)Parchment coffee (Arabica) was dried from an initial moisture content of about 90% to 10% dry basis (db) in a recirculating rotary conduction type heating unit at controlled plenum temperatures of 100, 120 and 140C or ... -
Coffee Sustainability in Kenya: Role Played by Improved Varieties
(2015)Coffee production in Kenya has been sinking since 1980s. The condition has been worsened by climate change phenomenon which has brought new production challenges in recent years. The biggest challenge is the changing ... -
Cognitive Conflict in Mathematics Teaching and Learning in Public Secondary Schools in Embu West Sub-County, Kenya
(University of Embu, 2021-09)Cognitive conflict is widely recognized as an important factor in the process of conceptual change and can be effectively utilized to promote the learning of mathematical concepts. However, there has been little research ... -
Cognitive Factors that Influence Information-seeking Behavioural Process Amongst Postgraduate Students: A Case Study from Kenyatta University Post-modern Library in Nairobi, Kenya
(2019)This article discusses the salient features of a case study carried out among postgraduate students at Kenyatta University Post-modern Library. The study was primarily focused at recognizing cognitive factors, responsible ... -
Cognitive Radio Sensing Using Hilbert Huang Transform
(Scientific Research Publishing, 2010-07)Vast segments of the frequency spectrum are reserved for primary (licensed) users. These legacy users often un-der-utilize their reserved spectrum thus causing bandwidth waste. The unlicensed (secondary) users can take ... -
Collembola Density and Diversity along a Gradient of Land- Use Types in Embu District, Eastern Kenya
(2009)Populations of soil-dwelling Collembola were monitored on a land use gradient ranging from Natural forests to intensively cultivated land during the wet season October-November, 2007 and dry season February-March, 2008. ... -
Collembola Richness and Diversity along A Land-Use Intensity Gradient in Taita, Kenya
(2009)Soil Collembola communities were sampled along a gradient of land use intensification in Taita-Taveta, Wundanyi division, Coast Province during the wet season (October-November 2007) and dry season (February- March ... -
Combined Antero-Posterior Inverted-U Metaphyseal and Open-Wedge Medial-Epiphyseal Osteotomy for Advanced Blount Disease
