Effects of Supplemental Irrigation on Crop Yields: Case Study Kales (Brassica Oleracea) Crop
(Journal of Ecological Engineering, 2020-02)
The aim of this study was to investigate the effects that supplemental irrigation (SI) has on Kale (Brassica Oleracea) crop yields as compared to wholly rain-fed crop. The experiments were conducted in Kieni, Central Kenya ...
Synthesis, structural assignments and antiinfective activities of 3-O-benzyl-carvotacetone and 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone.
(University of Nairobi, 2020)
In an attempt to synthesize carvotacetone analogues, new 3-O-benzyl-carvotacetone (10) and previously reported 3-hydroxy-2-isopropyl-5-methyl-p-benzoquinone (11) were synthesized from piperitone (7). In this work, we ...
Cultural heritage as a pathway for sustaining natural resources in the Maasai’s Pastoral Social-Ecological System in Kajiado County, Kenya
(African Journal of Agricultural Research, 2021-06)
The Maasai pastoralists inhabiting Kajiado County are known for rearing large herds of animals.
Livestock has enabled them to attain food and nutritional security. However, natural resources are
dwindling fast under the ...
Appraisal of Land Use Transformation using Remote Sensing in Kajiado County, Kenya
(International Journal of Ecology and Environmental Sciences, 2020-08-11)
Kajiado County is predominantly inhabited by the Maasai nomadic pastoralists who rely on natural systems for their provisions and production needs. Traditionally, communal land management has been the norm in the area but ...
Inhibition of Proinflammatory Cytokine Release by Flavones and Flavanones from the Leaves of Dracaena steudneri Engl
(University of Nairobi, 2021-03)
The leaves of Dracaena steudneri yielded 6 new flavonoids-3,5,7-trihydroxy-6-methyl-3',4'-methylenedioxyflavone (1: ), 5,7-dihydroxy-3-methoxy-6-methyl-3',4'-methylenedioxyflavone (2: ), 3,5,7-trihydroxy-6-methoxy-3',4'- ...
A CRISPR/Cas9-based genome-editing system for yam (Dioscorea spp.)
(University of Nairobi, 2021-04)
Reverse logistics and competitive advantage: the mediating effect of operational performance among manufacturing firms in Kenya
(European Scientific Journal, 2020-07-31)
Today globally, countries and manufacturing entities alike are concerned with environmental sustainability apart from economic gains. Implementation of reverse logistics programs has been contemplated as a feasible alternative ...
Handling missing data in a composite outcome with partially observed components: simulation study based on clustered paediatric routine data
(University of Nairobi, 2021)
Composite scores are useful in providing insights and trends about complex and multidimensional quality of care processes. However, missing data in subcomponents may hinder the overall reliability of a composite measure. ...
Optoelectronic property refinement of FASnI3 films for photovoltaic application
(University of Nairobi, 2021)
Tin (Sn) is a promising substitute for lead (Pb) in organic–inorganic hybrid halide perovskite-photovoltaic devices, but it is prone to delivering low power conversion efficiencies (PCEs) due to the poor quality of ...
On Unitary Invariance of Some Classes of Operators
(University of Nairobi, 2020)
It is a known fact in operator theory that two similar operators have equal spectra but they
do not necessarily have to belong to the same class of operators. However, under the
stronger relation of unitary equivalence ...
