Occurrence and abundance of plant parasitic nematodes in cabbage-based cropping systems in Kenya.
(2014-10)A survey was conducted to determine the incidences of plant parasitic nematodes (PPN) and factors enhancing population build-up in cabbage (Brassica oleracea L. var capitata)-based cropping system in selected agro-ecological ... -
Occurrence Of Bacterial Wilt Pathogen In Soils And Potato Tubers In Runyenjes In Embu County, Kenya.
(Research journali, 2021-04)Potato (Solanum tuberosum L.) is a starchy tuber crop that is widely cultivated in Africa as an income generator. Nutritionally, potato provides essential amino acids among other important body required nutrients. Despite ... -
Occurrence of fungal foliar diseases of tomato in different agro-ecological zones of Kirinyaga County, Kenya
(Fundamental and Applied Agriculture, 2022-03)Tomato production is characterized by inconsistent quality and yields due to biotic constraints such as fungal foliar diseases. Information on the occurrence of the diseases in different agro-ecological zones of Kenya is ... -
Occurrence of Pathogenic Bacteria Harboring Antibiotic Resistant Genes in River Njoro in Nakuru County
(2018)Njoro River drains an agricultural catchment whose main livelihood activities are livestock rearing and employment in light industries. The limited quantities of piped water supplies coupled with inadequate sanitary ... -

On Almost Similarity and Metric Equivalence of operators. Accepted for publication
(2016-06)In this paper, we investigate almost-similarity relation, metric equivalence and other relations of operators on Hilbert spaces. We characterize almost-similar, metrically equivalent operators. Roughly speaking, we consider ... -
On Almost Similarity Operator Equivalence Relation
(2013-06)We consider the almost similarity property which is a new class in operator theory and was first introduced by A. A. S. Jibril. We establish that almost similarity is an equivalence relation. Some results on almost similarity ... -
On Analytical Approach to Semi-open/Semi-closed sets in Metric Spaces”
(Science Publishing Group, 2017-03-03)The concept of open and closed sets has been extensively discussed on both metric and topological spaces. Various properties of these sets have been proved under the underlying spaces. However, scanty literature is available ... -
ON CHARACTERIZATION OF PERMUTATION GRAPHS
(Chuka University, 2020-12)Graph theory is an area in discrete mathematics with numerous theoretical developments and many applications to practical problems in computer science, chemistry, biology and operational research. As a result, it has ... -
On Characterization of u-ideals determined by sequences’’
(2013)The area of ideals is important in the study of Analysis, algebra, Geometry and Computer science. The various types of ideals have been studied, for example m ideals and h ideals. The m ideals defined on real Banach spaces ... -
On Similarity and Quasisimilarity equivalence relations
(2012-01)Similarity and unitary equivalence can be shown to be of equivalence relations. We discuss a result showing that two similar operators have equal spectra (i.e. point and approximate point spectrum). More ... -
On the Banach Space Numerical Range for a Linear Operator ",
(Modern Scientific Press Company, Florida, USA, 2019-03-25)The numerical range has been studied extensively in Hilbert spaces. Properties of the numerical range such as non-emptiness, containment of the spectrum and in particular, convexity have been proved and results have ... -
On The Convexity of A Generalized q-Numerical Range’’
(2005-01)For a given $q in kom$ with $|q| le 1$, we study the $C$-numerical range of a Hilbert space operator where $C$ is an operator of the form [ left( begin{array}{ccc} qI_n & sqrt{1-|q|^2}I_n \ 0_n & 0_n end{array} right) oplus ... -
On The Norm of an Elementary Operator of Finite Length in A C*Algebra”
(2018-08)Properties of elementary operators have been studied over the past years especially the norm aspect. Various results have been obtained on elementary operators of different lengths using different approaches. In this paper, ... -
On the Norm of Basic Elementary Operator in a Tensor Product
(2018-01)In this paper, we determine the norm of an elementary operator in a tensor product. More precisely, we investigate the bounds of the norm of a basic elementary operator in a tensor product. We employ the techniques of ... -
Opioid-Free Labor Analgesia: Dexmedetomidine as an Adjuvant Combined with Ropivacaine
(Journal of Healthcare Engineering, 2022)Background Side effects of the use of opioid analgesics during painless delivery are the main factors that affect rapid postpartum recovery. Opioid use can result in dangerous respiratory depression in the patient. Opioids ... -
Opportunities for Quality Seed Production and Diffusion through Integration of the Informal Systems in Sub-Saharan Africa
(videleaf, 2020)In perpetuating the preferred crop species, seed is exchanged among family members, neighboring communities or between tribes and regions according to customs and practices in many African traditions. Overtime, this ... -
Optical and scanning kelvin probe microscopic characterization of sol-gel synthesized aluminum doped zinc cobalt ferrite nanoparticles
(academic Journals, 2020)In this work, Zn1-xCoFe2AlxO4 (x=0, 0.2, 0.4, 0.6, 0.8 and 1.0) ferrites were synthesized using the sol-gel method. XRD analysis was done and confirmed the formation of spinel structure, where the particle size and lattice ... -
