Occurrence characteristics of equatorial plasma bubbles over Kisumu, Kenya during Solar maximum of Solar Cycle 24
(International Journal of Advanced Astronomy, 2021-01)Equatorial Plasma Bubbles (EPBs) are irregular plasma density depletions in the ambient electron density in the equatorial F-region ionosphere generated after sunset. EPBs are known to bring disruptions to telecommunication ... -

OCCURRENCE OF GROUNDNUT ROSETTE DISEASE AND DIVERSITY OF ITS CAUSAL AGENTS IN WESTERN KENYA
(MMUST, 2018-01)Groundnut (Arachis hypogaea L.) is an economically important edible oilseed legume in Sub-Saharan Africa (SSA). Nearly 75% to 80% of the world’s groundnut is grown by resource poor smallholder farmers in developing countries, ... -
OCCURRENCE, DISTRIBUTION AND MOLECULAR DIVERSITY OF GROUNDNUT ROSETTE ASSISTOR VIRUS CAUSING GROUNDNUT ROSETTE DISEASE IN WESTERN KENYA
(MMUST, 2020-02-20)Groundnut (Arachis hypogaea Linn) is an important legume in western Kenya, but yields are low and declining. Pests and diseases are ranked high among the yield reducing factors. Groundnut rosette disease (GRD) is the main ... -
On A Class of Idealized Near-Rings Admitting Frobenius Derivations.
(Journal of Advances in Mathematics and Computer Science, 2020-07-15)In this paper, we use the idealization procedure for finite rings to construct a class of quasi-3 prime Near-Rings N with a Jordan ideal J(N) and admitting a Frobenius derivation. The structural characterization of N; J(N) ... -
On Certain Spaces of Ideal Operators
(SCIENCE MUNDI, 2023-11-16)We determine some important spaces of ideal operators and ideal characteristics. Special consideration is given to Frechet spaces, Spaces of finite rank operators and spaces of Hahn-Banach extension operators. The ... -
On Characterization of Norm Attaining Operators in Fr´echet Spaces
(Journal of Advances in Mathematics and Computer Science, 2022-10-25)In this paper, the norm attaining operators in Fr´echet spaces are considered. These operators are characterized based on their density, normality, linearity and compactness. It is shown that the image is dense for a ... -
ON REGULAR ELEMENTS AND VON-NEUMANN INVERSES OF ZERO-SYMMETRIC LOCAL NEAR-RINGS WITH JORDAN IDEALS ADMITTING FROBENIUS DERIVATIONS
(2023-05)The study of near-rings with identity is very vital in generalizing characterization of commutative rings with identity. Much of the recent works on the classification of finite rings with identity have considered a ... -
On Some Aspects of Compactness in Metric Spaces
(AFRICAN SCIENTIFIC ANNUAL REVIEW, 2024-04-17)In this paper, we investigate the generalizations of the concepts from Heine-Borel Theorem and the Bolzano-Weierstrass Theorem to metric spaces. We show that the metric space X is compact if every open covering has a finite ... -
ON THE ADJACENCY AND INCIDENCE MATRICES OF THE ZERO DIVISOR GRAPHS OF A CLASS OF THE SQUARE RADICAL ZERO FINITE COMMUTATIVE RINGS
(International Journal of Pure and Applied Mathematics, 2018-04-16)The characterization of the zero divisor graphs of commutative finite rings has attracted a lot of research for quite sometime, however not so much has been done concerning their Adjacency and Incidence matrices. In ... -
ON THE ALGEBRA OF IDEALS AND MODULES IN OPERATOR SPACES
(2023)The Theory of Operator Ideals and Frechet Modules are important in the study of locally convex spaces, Rings and Algebras. Locally convex spaces are examples of topological vector spaces which generalize normed spaces, ... -
ON THE CHARACTERIZATION OF THE UNIT GROUPS OF A CLASS OF TOTAL QUOTIENT RINGS
(MMUST, 2017-10)Let R be a completely primary finite ring of characteristic pk, where p is a prime and k is a positive integer. Such finite rings have been studied extensively in recent years and the tools necessary for describing completely ... -
