Short-term dynamics of soil organic matter fractions and microbial activity in smallholder potato-legume intercropping systems
(University of Nairobi, 2019)
Continuous cultivation of potato (Solanum tuberosum L.) in monoculture systems represents the greatest factor deteriorating soil organic matter (SOM) in smallholder farms. With an aim to breaking this norm, a 2-year field ...
Controlling soil erosion in smallholder potato farming systems using legume intercrops
(University of Nairobi, 2019)
Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field ...
Groundwater hydrodynamics of an Eastern Africa coastal aquifer during the recent La Niña 2016-17 drought
(University of Nairobi, 2019)
In 2016-17 much of East Africa was affected by a severe drought which has been attributed to Indian Ocean Dipole and El Niño Southern Oscillation conditions. Extreme events such as this have immediate and knock-on effects ...
The Potential For CO2 Geosequestration In Kenya: A Suitability Assessment Of The Lamu Basin
(University of Nairobi, 2019)
There is a consensus that current trends in climate change may be due to increasing concentrations of greenhouse gases (predominantly methane and carbon dioxide) from anthropogenic emissions. Among measures proposed for ...
Occurrence and distribution of organochlorine pesticide residue levels in water, sediment and aquatic weeds in the Nyando River catchment, Lake Victoria, Kenya
(University of Nairobi, 2019)
Samples of water, sediments and aquatic weeds were collected from 26 sites in the Nyando River catchment of the Lake Victoria basin in 2005–2006. The objective was to investigate levels of organochlorine pesticides that ...
Development and Implementation of a Mobile Phone-Based Prevention of Mother-To-Child Transmission of HIV Cascade Analysis Tool: Usability and Feasibility Testing in Kenya and Mozambique.
(University of Nairobi, 2019)
BACKGROUND:
Prevention of mother-to-child HIV transmission (PMTCT) care cascade failures drive pediatric HIV infections in sub-Saharan Africa. As nurses' clinical and management role in PMTCT expand, decision-support ...
Characterization of vB_ApiM_fHyAci03, a novel lytic bacteriophage that infects clinical Acinetobacter strains.
(University of Nairobi, 2019)
We present here the isolation and characterization of Acinetobacter pittii phage vB_ApiM_fHyAci03 (fHyAci03), which belongs to the family Myoviridae. The fHyAci03 genome was found to be 165,975 bp in length and predicted ...
Clinically relevant antimicrobial resistance at the wildlife-livestock-human interface in Nairobi: an epidemiological study.
(University of Nairobi, 2019)
BACKGROUND:
Antimicrobial resistance is one of the great challenges facing global health security in the modern era. Wildlife, particularly those that use urban environments, are an important but understudied component ...
Antiretroviral drug-induced endothelial dysfunction is improved by dual PPARα/γ stimulation in obesity.
(University of Nairobi, 2019)
Obesity rates are rising in HIV-infected populations; however, the putative role of highly active antiretroviral therapy (HAART) in the development of endothelial and cardiovascular derangements in the presence of pre-existing ...
Advances in green nanobiotechnology: Data for synthesis and characterization of silver nanoparticles from ethanolic extracts of fruits and leaves of Annona muricata.
(University of Nairobi, 2019)
n this data article, data obtained from an efficient, eco-friendly and low-cost method for the synthesis and recovery of Silver nanoparticles (AgNPs) using ethanolic extracts of Annona muricata fruits and leaves as reducing, ...
