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 ...
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 ...
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 ...
Photo-thermal Conversion Efficiency of Textured and Untextured Aluminum Substrate Coated With Titanium Dioxide (Tio2)-bound Cufemno4 Absorber
(University of Nairobi, 2020)
The possibility of obtaining thermal energy from the sun for household bathing and washing has resulted to growth in market for solar thermal applications with new types of solar absorbers ...
Determinants of Mobile Fintech Uptake in Kenyan Microfinance Sector
(University of Nairobi, 2020)
The Kenyan microfinance sector faces many challenges such as high operation costs, increased credit risk, low visibility and poor understanding of emerging technology opportunities and risks among others. These problems ...
Further remarks on unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)
n this paper we investigate results on unitary equivalence of operators that include n-binormal, skew
binormal and n-power-hyponormal operators acting on complex Hilbert space H. AMS subject classification ...
On unitary equivalence of some classes of operators in Hilbert spaces
(University of Nairobi, 2020)
Abstract
It is a well-known result in op erator theory that whenever two op erators are similar then they have equal
sp ectra even though they do not have to belong to the same class of op erators. However ...

(University of Nairobi, 2020)
Introduction: Reports of emergence of Artemisinin Combination Therapies (ACTs) resistant malaria parasites in Greater Mekong region and Equatorial Guinea, is a strong reason necessitating increased efforts to discover
new ...
