Land use systems and distribution of trichoderma species in Embu
(School of Biological Sciences, 2007)The distribution of Trichoderma species in soils of Embu region in relation to land use practices was investigated. The study area was chosen because of its significant land use intensification. Soil washing and dilution ... -
Land-based activities, pollution sources and levels in water and sediment in the coastal and marine area of Kenya
(2006)Kenya has a land area of 580,000 km2 and lies astride the equator. It has a coastline bordering the Indian Ocean, which runs about 600 km long in a south-westerly direction with varying, marine and coastal wetlands rich ... -
Land-snail faunas of afromontane forests of Mount Kenya, Kenya: ecology, diversity and distribution patterns
(University of Nairobi, 2001-06)Aims To (1) describe the distribution patterns of land-snails occurring in afromontane forest habitats on Mount Kenya, in relation to elevation and aspect; (2) explore the relations between the land-snail faunas and ... -
Laparoscopic versus open distal pancreatectomy in pancreatic tumours: a case–control study
(2010)Laparoscopic distal pancreatectomy has become an increasingly used procedure in the surgical treatment of benign or borderline cystic and endocrine tumours. The feasibility and safety of this technique is well known but ... -
Laplace Transform solution of Hydro magnetic steady flow problem of viscous incompressible fluid flowing between two parallel infinite plates with constant applied pressure gradient

Large-scale Irregularities In The Equatorial Ionosphere
(University of Nairobi, 1975-04)Variations in the Faraday fading period of the 40 MHz signal from satellite BE-B have been used to study large-scale irregularities in the equatorial ionosphere. It is found that the irregularities have sizes ranging from ... -
Large-scale variation in lithospheric structure along and across the Kenya rift.

Larval habitats of common Culicoides Latreille (Diptera, Ceratopogonidae) in Kenya
(Department of Entomology, University of Nairobi, Kenya, 1976)The larval habitats of Culicoides species were determined by examining a total of 1 476 samples collected from different ecological environments in various parts of Kenya. Immature stages were collected from suspected ... -
Larvicidal Activities Of Extracts And Rotenoids From Millettia Usaramensis Subspecies Usaramensis On Aedes Aegypti (Linnaeus, 1762) (Diptera: Culicidae)
(University of Nairobi, 2014)The dichloromethane/methanol (1:1) extract of the stem bark of Millettia usaramensis subspecies usaramensis was tested for its larvicidal activity against the 4th instar Aedes aegypti larvae and demonstrated activity with ... -
Larvicidal Activities Of The Stem Bark Extract And Rotenoids Of Millettia Usaramensis Subspecies Usaramensis On Aedes Aegypti L. (diptera: Culicidae)
(University of Nairobi, 2014)The dichloromethane/methanol (1:1) extract of the stem bark of Millettia usaramensis subspecies usaramensis was tested for its larvicidal activity against the 4th instar Aedes aegypti larvae and demonstrated activity with ... -
Larvicidal activity of a granular formulation of a Melia volkensii (Gurke) acetone extract against Aedes aegypti L
(Department of Zoology, University of Nairobi, 1998)A method of formulating granules from an acetone extract fraction of the fruit of Melia volkensii, a Kenyan tree known to possess insecticidal properties, was developed. The granules were tested for toxicity to third and ... -
Larvicidal benzoquinone from Embelia schimperi
(Department of Chemistry, 2004)Chromatographic analysis of air-dried berries of Embelia schimperi led to the isolation of methyl vilangin (1), which was characterized on the basis of physical and spectroscopic data. The compound was found to be lethal ... -

Laser induced breakdown spectroscopy and characterization of environmental matrices utilizing multivariate chemometrics
(2013)We exploited multivariate chemometric methods to reduce the spectral complexity and to retrieve trace heavy metal analyte concentration signatures directly from the LlBS spectra as well as. to extract their latent char ... -
Late Cenozoic fluvial dynamics of the River Tana, Kenya, an uplift dominated record
(University of NairobiDepartment of Geology, 2007-11)The Late Cenozoic development of the River Tana in Kenya has been reconstructed for its central reach near its confluence with the River Mutonga, which drains the Mount Kenya region. Age control for this system has been ... -
Late Holocene sedimentology and palaeoenvironment of Kiluli Swamp, Mount Kenya
(2003)Kiluli Swamp is an extensive valley swamp near the lower limit of the montane forest on the eastern slopes of Mount Kenya, East Africa. The swamp is fed by a small spring on the northeastern margin, and the water table ...
