A note on ( k;f;l )-chordal polygons
(University of Nairobi, 2000)In this article the results concerning the existence of ( k;f;l )- chordal polygons that appeared in [2, 3] are generalized by using a theorem presented in [1]. Furthermore, it is pointed out that there is an error in a ... -
A note on a-self -adjoint and a-skew -adjoint operators and their extensions
(School of mathematics, 2012)In this paper we introduce the notions of an A-self-adjoint, an A-skewadjoint linear operator, where A is a self-adjoint and invertible operator and related classes of operators, which generalize some known classes ... -
A note on metric equivalence of some operators
(Pushpa Publishing House, Allahabad, INDIASchool of mathematics, 2012)In this paper, we study the metric equivalence relation and closely related relations on some classes of operators. We describe the spectral picture of metrically equivalent operators. We give some conditions when metric ... -
A note on planarity stratification of hurwitz spaces
(University of Nairobi, 2014-08)Abstract. One can easily show that any meromorphic function on a comple x closed Riemann surface can be represented as a composition o f a birational map of this surface to CP 2 and a projection of the image curve ... -
A note on quasi-similarity of operators in Hilbert spaces
(2015)In this paper we introduce the notion of Quasi-similarity of bounded linear operators in Hilbert Spaces. We do so by defining a quasi- affinity from one Hilbert Space H to K. Some results on quasi- affinities are also ... -
A note on similarity, almost -similarity and equivalence of operators
(School of Mathematics, University of Nairobi,, 2007)The almost- similar and similar relations between operators on finitedimensional Hilbert spaces are investigated. It is shown that almost similar operators share some properties with some other classes of operators. ... -
A NOTE ON THE SUSCEPTIBILITY OF SOME GASTROPOD MOLLUSCS TO SCHISTOSOMA BOVIS AND S. MATTHEEI.
(University of Nairobi.Department of Zoology, 1984-09) -
A note on the Temperature distribution of a Viscous Incompressible Fluid in a channel Bounded by two parallel plates.
(University of Nairobi.School of Mathematics, 1973) -

A novel dihydroxy gymnemic triacetate isolated from Gymnema sylvestre possessing normoglycemic and hypolipidemic activity on STZ-induced diabetic rats.
(University of NairobiCollege of Biological and Physical Sciences, 2009)Aim of the study: Gymnema sylvestre (Asclepiadaceae) is emerging as a potential treatment for the management of diabetes. The leaves are used in herbal medicine preparations. The present study was carried out to isolate ... -
Novel Escherichia coli-Infecting Bacteriophages Isolated from Uganda That Target Human Clinical Isolates
(University of Nairobi, 2023)Background: The antimicrobial resistance catastrophe is a growing global health threat and predicted to be worse in developing countries. Phages for Global Health (PGH) is training scientists in these regions to isolate ... -
Novel Rickettsia and emergent tick-borne pathogens: A molecular survey of ticks and tick-borne pathogens in Shimba Hills National Reserve, Kenya
(University of Nairobi, 2017-02)Ticks are important vectors of emerging and re-emerging zoonoses, the majority of which originate from wildlife. In recent times, this has become a global public health concern that necessitates surveillance of both known ... -
A novel Steroid1 from Elephantopus scaber L. an Ethnomedicinal plant with antidiabetic activity
(University of NairobiCollege of Biological and Physical Sciences, 2009-03)Acetone extract of Elephantopus scaber, an ethnomedicnal plant, reduced the blood glucose levels in streptozotocin-induced diabetic rats significantly. Acute toxicity studies revealed the non-toxic nature of the crude ... -
A novel synthetic odorant blend for trapping of malaria and other African mosquito species
(2012)Estimating the biting fraction of mosquitoes is of critical importance for risk assessment of malaria transmission. Here, we present a novel odor-based tool that has been rigorously assessed in semi-field assays and ... -
A Novel Terpenoid from Elephantopus Scaber - Antibacterial Activity on Staphylococcus Aureus: A Substantiate Computational Approach
(University of NairobiCollege of Biological and Physical Sciences, 2008-09)Staphylococcus aureus has gainedmuch attention in the last decade as it is a major cause of the Urinary Tract Infection in Diabetic patients. The Extended Spectrum β-Lactamases (ESβL) producers are highly resistant to ... -
NPP Grassland: Nairobi, Kenya, 1984-1994
(University Of Nairobi, 1996)Net primary production of a savanna grassland in Nairobi National Park, Kenya, was determined from 1984 to 1994 by monitoring monthly dynamics of live biomass and dead matter, above and below ground, together with monthly ... -
nth-Aluthge transform of w-Hyponormal Operators
(Pushpa Publishing HouseSchool of Mathematics, University of Nairobi, 2011)In this paper, it is shown the exact location of w-hyponormal operators in a series of operator classes and that; the spectrum of the nth-Aluthge transform of any operator equals that of the operator and for w-hyponormal ... -
Numerical simulation of vibration of horizontal cylinder induced by progressive waves
(University of Nairobi, 2016)Maritime structures often comprise cylinders of small diameter relative to the prevailing wave length. This paper describes the direct forcing immersed boundary simulation of the hydroelastic behaviour of a rigid, horizontal ...
