Long-term use of permethrin-impregnated nets does not increase Anopheles gambiae permethrin tolerance
(University of NairobiDepartment of Zoology, 1996)Previous use of permethrin-impregnated bednets (mosquito nets) and curtains in four Kenyan villages for one year, 1990-91, raised the permethrin LT50 of Anopheles gambiae to 2.4-fold above its baseline value, designated ... -

Lorentz- Non-invariance Effect on Flavour Oscillations, General Relativity and Gravitation
(University of NairobiDepartment of Physics, 2003)Flavour Oscillation is considered in the Finslerian model of space-time. It is shown that the contribution to the oscillation phase shift coming from torsion is non-geometric and anisotropy dependent. -

Louisiana crayfish (Procambarus clarkii) (Crustacea: Cambaridae) in Kenyan ponds: non-target effects of a potential biological control agent for schistosomiasis
(Taylor & Francis, 2010)The Louisiana crayfish (Procambarus clarkii) has been proposed as a biological control agent for the intermediate snail hosts (Bulinus and Biomphalaria spp.) of human schistosomes (Schistosoma haematobium and S. mansoni) ... -

Low enthalpy geothermal systems in Kenya
(University of Nairobi, 1988)The location of Kenya's geothermal fields is shown. The chemistry of the low enthalpy fields is given and reservoir temperatures estimated from these data. The most promising of these fields are the Mwananyamala, Homa ... -
Low Frequency Dielectric Loss Measurements On Al2o3 Films
(University of Nairobi, 1982-08)Measurements of the dielectric loss in thin Al2O3 films at low and very low frequencies are reported. A very simple but efficient experimental technique for measuring the loss tangent was used in the study. A Debye-type ... -
Low Latitude Ionospheric Scintillation And Zonal Irregularity Drifts Observed With GPS-SCINDA System And Closely Spaced VHF Receivers In Kenya
(University of Nairobi, 2013-05)In this study we have used VHF and GPS-SCINDA receivers located at Nairobi (36.8°E, 1.3°S, dip −24.1°) in Kenya, to investigate the ionospheric scintillation and zonal drift irregularities of a few hundred meter-scale ... -
Low-level Plasmodium falciparum transmission and the incidence of severe malaria infections on the Kenyan coast.
(University of Nairobi.Department of Zoology, 1993-08)The transmission of Plasmodium falciparum was studied in relation to the incidence of severe malaria infections at Sokoke and Kilifi town, Kilifi District, Kenya. Intensive mosquito sampling during a one-year period yielded ... -
Lower crustal seismicity, volatiles, and evolving strain fields during the initial stages of cratonic rifting
(University of Nairobi, 2014-12)The volcanically active East African rift system in southern Kenya and northern Tanzania transects thick cratonic lithosphere, and comprises several basins characterized by deep crustal seismicity. The US-French-Tanzania-Kenya ... -

Luni-solar variations in f0F2 at four African stations
(University of Nairobi, 1974-09)The luni-solar tidal oscillations in f0F2 at Djibouti, Tamanrasset, Lwiro and Nairobi have been examined and the results are presented in the form of percentage amplitude spectra. These show some consistent common features ... -
