Late Holocene variations from Lake Rutundu, mount Kenya
(Department of Geology, University of Nairobi, 2013) -
Late Pleistocene-Holocene rise and collapse of Lake Suguta, northern Kenya Rift.
(2009)The Late Pleistocene to Middle Holocene African Humid Period (AHP) was characterized by dramatic hydrologic fluctuations in the tropics. A better knowledge of the timing, spatial extent, and magnitude of these hydrological ... -
The late Proterozoic Yatta Shear Zone: A possible lateral ramp extending across the Kenya Rift
(1994)On the basis of a test experiment in 1985 (KRISP 85) an integrated seismic-refraction/ teleseismic survey (KRISP 90) was undertaken to study the deep structure beneath the Kenya rift down to depths of NO-150 km. This ... -
Late quaternary climatic variability in intertropical Africa
(Springer,Department of Geology University of NairobiSchool of Ocean Sciences University of Wales BangorDepartment of Geography University of Wales SwanseaGeological Institute University of BergenDepartment of Geography Lancaster University, 2004) -
Late Quaternary environmental change in southern Africa
(bDepartment of Geology, University of Nairobi, Nairobi,Climatology Researcl1 Group. University of the Witwatersrand., 2001)Over the last 400 000 years, the pattern of climatic change in the southern African sector of the southern hemisphere is shown to have followed in broad outline that defined by the Vostock ice-core sequence. Regional-local ... -
Late Quaternary glacial-interglacial cycle of climatic and environmental change on Mount Kenya, Kenya
(University of NairobiDepartment of Geology, 1999-10)Sediments from Sacred Lake and Lake Nkunga on the northeastern flank of Mount Kenya have a sequential palaeoclimatic and palæoenvironmental record covering most of the Late Quaternary period: from ca 115 to 0 ka. Most of ... -
Late Quaternary primary tephras in Sacred Lake sediments, northeast Mount Kenya, Kenya
(University of NairobiDepartment of Geology, 2000-05)In this paper, a sequence of five Late Quaternary tephras occurring as discrete, well-preserved horizons in lake sediments on the northeastern flank of Mount Kenya are characterised and their ages determined by a combination ... -
LC-GC, SFC-GC and SFC and SFE-GC interfacing
(Department of Chemistry, 1988) -
LC-MS-Based Metabolomics for the Chemosystematics of Kenyan Dodonaea viscosa Jacq (Sapindaceae) Populations
(University of Nairobi, 2020)Dodonaea viscosa Jacq (Sapindaceae) is a medicinal plant with a worldwide distribution. The species has undergone enormous taxonomic changes which caused confusion amongst plant users. In Kenya, for example, two varieties ... -
Lead contamination in street soils of Nairobi city and Mombasa island
(Department of Chemistry, 1991) -
Lead content in automotive paints purchased at formal and informal outlets in Kenya
(University of Nairobi, 2023)Lead (Pb) is added to automotive paints to prevent corrosion on metallic surfaces, for decorative colours, and for reflective properties to heighten visibility, and enhanced drying time, and durability. However, there are ... -
Lead Exposure and Blood Pressure among Workers in Diverse Industrial Plants in Kenya
(2014)The study evaluated airborne exposures and blood lead (BPb) levels in 233 production workers at six diverse industrial plants in Kenya. Blood and personal breathing zone air samples were collected and analyzed for lead ... -
Leaf blight disease of strawberries in Kenya caused by Dendrophoma obscurans
(School of Biological Sciences, 1988) -
Leaf compounds in potential plantation species of Aloe in Kenya
(1997)Many Aloe species are valued for the healing properties associated with the leaf tissues, a factor that has led to over-exploitation of natural populations and endangerment of some local Kenyan species. While trade in ... -
Leaf disc regeneration of passion fruit
(School of Biological Sciences, 1999)A leaf disc regeneration system was developed for passion fruit, Passiflora edulis Sims. Leaf discs were cultured on a modified MS medium containing 8.90 µM BAP or on 8.90 µM BAP and 2.32 µM KIN. Shoots appeared within ... -
Leaf stomata conductance, leaf water potential and soil water status in panicum maximum (JACQ.) in disturbed and non-disturbed microsites in a semi-arid ecosystem in Kenya
(Jomo Kenyatta University of Agriculture and Technology, 2011)Tropical semi-arid ecosystems are intricate ecosystems characterized by alternating dry-wet cycles. The question of how trees and grasses coexist under a considerable range of environmental and management conditions has ... -
Leaf storage conditions and genomic DNA isolation efficiency in Ocimum gratissimum L. from Kenya
(University of NairobiSchool of Biological and Physical Sciences, 2008)Storage of plant tissues for DNA is important to avoid degradation of DNA. Preliminary studies were conducted on Ocimum gratissimum L. in order to establish the storage conditions for the collected samples before DNA ...
