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 ... -
Ecology of Echinometra mathaei (Echinoidea: Echinodermata) at Diani Beach, Kenya
(Department of Zoology, University of Nairobi, Nairobi, Keny, 1971)Studies were carried out on the inner and outer coral reefs at Diani Beach on the Kenya coast to assess the distribution, density and behaviour of Echinometra mathaei (de Blainville). Transects 1 m wide were run on the two ... -
On The Dual Bishop Darboux Rotation Axis Of The Dual Space Curve
(University of NairobiDepartment of Mathematics, Usak, Turkey, 2000)In this paper, the Dual Bishop Darboux rotation axis for dual space curve in the dual space D3 is decomposed in two simultaneous rotation. The axes of these simultaneous rotation are joined by a simple mechanism. -

Mathematical Models And Numerical Simulationsfor The P 53-mdm2 Network
(University of NairobiDepartment of Biophysics and Medical Informatics, (Medicine and Pharmacy), Romania, 2000)Guardian of the genome, p53 gene, and its partners that form the complex network involved in apoptosis and cell cycle arrest, is put under investigation. Some relevant mathematical models are described and each of them ... -
Solid-phase peptide synthesis of isotocin with amide of asparagine protected with 1-tetralinyl. Rifluoromethanesulphonic acid (tfmsa) deprotection, cleavage and air oxidation of mercapto groups to disulphide
(Department of Chemistry, University of Nairobi, 2001)Isotocin, a nonapept ide amide, was synthesised on a benzhydryl-resin using the Bocst rat egy. Benzyl group was used in the pr otect ion of the side-ch ains of tyrosine, ser ine and cyst eine. Tetr alinyl group was used ... -

Two Stage Interest Rate Pass Through In Kenya
(School of Business, University of NairobiSchool of Mathematics, University of Nairobi, 2013)Interest rate volatility is a major concern for emerging economies due to its crippling effects on the economy. There is wide ranging disconsensus on the effectiveness and speed of various tools. This paper proposes ... -
Mutual inhibition in a two species chemostat-like system
(School of Mathematics, University of Nairobi,Department of Mathematics, Masinde Muliro University of Science and Technology,, 2013)A general model of the chemostat with mutual inhibition is provided in this paper. Global behavior of the solutions of this model are discussed and we show that for two species competing for a single nutrient available ... -
APPLICATION OF TETRALINYLS AS CARBOXAMIDE PROTECTING GROUPS IN PEPTIDE SYNTHESIS
(Department of Chemistry, University of Nairobi, 1998). I-Tetralinylamines were used as precursors to prepare the carboxamide protected derivatives of asparagine (lb-5b) and glutamine (la-Sa). The carboxamide protected derivatives were then subjected to cleavage studies in ... -
A Classification Of Points On The Sierpinski Gasket
(University of NairobiDepartment of Mathematics, Anadolu University, Turkey, 2000)In this article we classified the points of the well-known fractal set Sierpinski Gasket (SG) according to their addresses. We also gave a characterization of points of SG -
On The Ordered Sets In n-Dimensional Real inner Product Spaces
(University of NairobiDepartment of Mathematics, Faculty of Science and Arts, Afyon Kocatepe University, Turkey., 2000)Let X be a real inner product space of dimension ¸ 2. In [2], W. Benz proved the following theorem for x; y 2 X with x < y: "The Lorentz-Minkowski distance between x and y is zero (i.e., l (x; y) = 0) if and only if [x; ... -
