Triblock copolymers of lactide with poly(ethylene glycol) and influence of stereochemical composition
(2003)Polymerization of L-lactide (LLA) and poly(ethylene glycol) (PEG) at 120°C using stannous 2-ethyl hexanoate results in ABA triblock copolymers in good yields. The glass transition temperature of the copolymers shows strong ... -
Multicomponent Polymers of Poly(Lactic Acid) Macromonomers with Methacrylate Terminal and Copolymers of Poly(2-Hydroxyethyl Methacrylate
(1996)Poly(lactic acid) macromonomers with methacrylate terminal functionality have been synthesized from the cyclic dimer of lactic acid (referred to as lactide) with 2-hydroxyethyl methacrylate (HEMA) as initiator and stannous ... -
A Synoptic Ecopath model of biomass flows during two different static ecological situations in Lake Nakuru (Kenya)
(Department of Zoology, University of NairobiInland Fisheries Department, INP/ENSAT, P.O. Box 107, Auzeville Tolosane, 31 326, Castanet Tolosan, France, 2001)Trophic relationships inside the Lake Nakuru ecosystem during two different phases are described by using the ECOPATH model. This allows a partial explanation of the ecological changes observed in the lake and to show that ... -
Distribution of Cr, Pb, Cd, Zn, Fe and Mn in lake Victoria sediments, East Africa
(Department of Chemistry, University of Nairobi, 1989)The presence of many metals at trace or ultra-trace levels in the human environment has received increased global attention. Sediments as a sink for pollutants are widely recognized pollution sources and diagenesis and ... -
Prevalence of ixodid ticks and trypanosomosis in camels in southern rangelands of Ethiopia
(University of Nairobi.school of Biological Sciences, 2004)The prevalence of ixodid ticks and trypanosomosis of camels was studied in the semi-arid rangelands of southern Ethiopia between 1995 and 1996. A total of 24077 ticks were collected from 510 camels aged between 6 months ... -
Fish species composition and distribution in Kilifi Creek
(School of Biological Studies, University of NairobiKenya Marine and Fisheries research Institute, Mombasa, 2009)Ecological variation along the Kenyan coast influences fisheries composition. Kilifi Creek is a unique ecosystem along this coast because it is an open lagoon. A study of the fisheries fauna of Kilifi Creek was conducted ... -

Using Adaptive Link Hiding to Provide Learners with Additional Learning Materials in a Web-Based System
(2012)Today’s Internet Generation is accustomed to multi-ta sking, graphics, fun, and fant asy. Educators in Asia are finding it increasingly challenging to engage and mo tivate students with traditional modes of teaching. One ... -
Human impact on lake ecosystems: the case of Lake Naivasha, Kenya
(College of Biological Sciences, University of Nairobi, 2007)Lake Naivasha is a wetland of national and international importance. However, it is under constant anthropogenic pressures, which include the quest for socioeconomic development within the lake ecosystem itself as well ... -
A corpus-based survey of four electronic swahili–english bilingual dictionaries
(School of Computing and Informatics, University of Nairobi, 2009)In this article we survey four different electronic bilingual dictionaries for the lan-guage pair Swahili–English. Aided by a data-driven morphological analyzer and part-of-speech tagger, we quantify the coverage of the ... -
Pathogenicity of the entomopathogenic fungus Metarhizium anisopliae to the red-legged tick, Rhipicephalus evertsi evertsi
(University of Nairobi.school of Biological Sciences, 2011)Rhipicephalus evertsi evertsi is an economically-important tick of livestock in Africa mainly due to its ability to transmit Babesia equi to horses, Anaplasma marginale to cattle and to cause paralysis in lambs, adult sheep ... -
Towards English - Swahili Machine Translation
(School of Computing & Informatics, University of Nairobi,, 2011)Even though the Bantu language of Swahili is spo- ken by more than fifty million people in East and Central Africa, it is surprisingly resource-scarce from a language technological point of view, an unfortu- nate ... -
