The complimentary role of wild habitats in crop pollination: A case study on the eggplant (Solatium melongena L., Solanaceae)
(2001)In this study, carried out in Nguruman, southwestern Kenya, 10 bee species were identified as eggplant pollinators. Their foraging behaviour was shown to be affected by the prevailing ambient temperature and not time of ... -
Abundance and control of malaria mosquito larvae in the traditional water management agro-ecosystem of Kasagam, western Kenya /
(2009)This study investigated the abundance and control of malaria mosquito larvae in a traditional water management agro-ecosystem of Kasagam, Kisumu City, western Kenya. The study of larval habitats of malaria vectors is ... -
Simulation of the charge ratio of cosmic ray muons in extensive air showers using corsika
(2010-08)The interaction of primary cosmic rays in the atmosphere produces, among other particles, pions and kaons. They decay to muons, which form an important component of extensive air showers, which can be measured on the Earth's ... -
The Influence of ICT Usage on Academic Performance in Secondary Schools in Rarieda Sub-County of Siaya County.
(2014)Provision, adequacy, utilization and management of educational facilities largely determine the quality and standards of education offered in a school yet there has been tremendous growth in students' ... -
Assessment of the Level of Compliance by the Universities to their ICT Security Policies: A Survey of Kisumu and Siaya Counties
(JOOUST, 2015)Today, almost all organizations around the world are using Information Communication Technology (ICT) in their daily business. An lCT policy safeguards Confidentiality, Integrity and Availability (ClA) of ... -
Mathematical Model for Drug Therapy in Asthmatics
(JOOUST, 2016)Asthma is a chronic disease that involves inflammation of the airways. Pa¬tients with Asthma have a constriction of the airways in the lungs and con¬sequent difficulty in breathing out. This ailment can be alleviated by ... -
Mathematical Model for Nutrients and Wastes Exchange Across The Placenta.
(JOOUST, 2016)The use of differential equations is worldwide and arises quite often in biological and physical applications. Differential equations have been used to create mathematical models of real world systems in which rates of ... -
On norm preserving conditions for local automorphisms of commutative banach algebras
(2016)Many studies on preserver problems have been focusing on linear preserver problems in matrix theory. Kadison and Sourour showed that the local derivations of Von Neumann algebras are continous linear maps which coincide ... -
Solution of parabolic partial differential equation of the form ut = uxx + f(x; t) u using lie symmetry analysis
(JOOUST School of Mathematics & Actuarial Sciences, 2016-05)The investigation of the exact solutions of nonlinear PDEs plays an important role in the study of nonlinear physical phenomena for instance in shallow water waves, uid physics, general relativity and many others.Lie ... -

On Norm Preserving conditions for Local Automorphisms of Commutative Banach Algebras
(JOOUST, 2017)Most studies on preserver problems have been on linear preserver prob¬lems (LPPs) in matrix theory. It is known that local derivations of Von Neumann algebras are continuous linear maps, which coincide with some derivation ... -
Norms and Maximal Numerical Range of Jordan Elementary Operators
(JOOUST, 2017)Elementary operators originated from the study of the Sylvester and Rosenblum equation AX - X B = Z. Although a lot of work on vari¬ous properties of elementary operators has been done, the norm property still remains an ... -

(JOOUST, 2017-05) -
Tensor Products and Norms of Inner Derivations Induced by Norm-Attainable Operators
(JOOUST, 2018)Several investigations have been done on properties of derivations act¬ing on C* -algebras and their subalgebras and these include their norms, boundedness, numerical ranges, spectra and the operators inducing them. The ... -
Bilateral Shifts and Spectrum of Compact Operations
(JOOUST, 2018)Shift operators are important operators in functional analysis in the study of other operators like compact operators, finite operators, normal opera-tors among others. Left shifts, right shifts and unilateral shifts have ... -
Numerical Solution of Dynamic Vibration Equation with Restoring Force x = sech x
(JOOUST, 2018)Dynamic vibration equations are of great importance not only for un-derstanding the dynamic motion of structures, but also for providing knowledge of differential equations to mathematicians. Although sev¬eral studies have ... -
On Norms of Normally Represented Elementary Operators.
(JOOUST, 2018)The' study of elementary operators has been of great interest dating back to many decades when it was initiated by Sylvester in 1884.A number• of scholars have described several properties of elementary ... -
Lie Symmetry Analysis of Third Order NonLinear Ordinary Differential Equation
(JOOUST, 2018)A few third order nonlinear Ordinary Differential Equations can be solved explicitly and one must typically rely on numerical scheme to approximate the solution. However to overcome this problem Lie symmetry reduction of ...
