Putnam’s inequality for n-Power normal, n-Power quasinormal and w-hyponormal operators,
(University of Nairobi, 2014)
Every reducible operator can be decomposed into normal and completely non-normal operators.
Unfortunately, there are several non normal operators which are irreducible. However, every
operator whose self-commutator is ...
Determinants of antibiotic dose adjustment in patients with chronic kidney disease at Kenyatta National Hospital Kenya
(University of Nairobi, 2014)
Background: Reduced renal function in chronic kidney disease (CKD) necessitates appropriate dose alterations to avoid drug accumulation.
Objectives: The main objective of the study was to determine the prevalence of ...
Polyaniline and Polythiophene Modified Electrodes in Energy Storage Units with hydrocarbon gel/Bentonite/Sodium Chloride as Electrolyte Gel
(University of Nairobi, 2014-05)
In this paper we present results obtained for energy storage units developed using polyaniline and
polythiophene modified electrodes. The voltage potential prof
iles for recharge/discharge are either linear or
exponential. ...
Castration causes progressive reduction of length of the rabbit penis
(University of Nairobi, 2014)
Androgenic hormones are important in normal embryonic
development and maintenance of the
structural integ
rity of the penis
. This structural integrity is vital in the physiology of penile
erection. Its alteration may ...
Electro-Characterization of Polypyrolle Electrosynthesized on a Montmorillonite Host-Matrix, in Aqueous Media Containing Sulphuric Acid as Supporting Electrolyte
(University of Nairobi, 2014-05)
In this paper polypyrolle has been electrosynthesised from an aqueous media containing the pyrolle monomer and sulphuric acid as the supporting electrolyte.
The redox properties of polypyrolle on carbon graphite working ...
Experimental Solidification Projection, Liquidus Surface Projection and Isothermal Section at 1000 °C for the Pt-Cr-V System
(University of Nairobi,, 2014-06)
Alloys of the Pt-Cr-V were studied in the as-cast and heat treated conditions using scanning electron microscopy with energy dispersive x-ray spectroscopy and x-ray diffraction. The solidification projection and isothermal ...
Dynamic channel sharing strategies through game-theoretic reinforcement learning
(University of Nairobi, 2014-03)
—Random access protocols are used by multiple nodes in
wireless networks to effectively share a wireless channel for data
transmission. While competing for the channel, the nodes seek to
achieve an individual or group ...
Investigation of Kenyan bentonite In Adsorption of some Heavy metals In aqueous Systems using cycli voltammetric techniques
(University of Nairobi, 2014-03)
Potential application of Kenyan bentonite for adsorption of iron, cobalt, copper, nickel and zinc and for analysis of electroactive species in water from a polluted water course using a 3-electrode potentiostat and cyclic ...
Solid-Phase Peptide Synthesis of Arginine-vasopressin with Amide Side-chain of Asparagine Protected with 1-Tetralinyl Group
(University of Nairobi, 2014)
Arginine-vasopressin, a nonapeptide amide, was synthesized on a benzhydryl-resin using the Boc-strategy. Benzyl group was used in the protection of sulfhydryl group of cysteine and tyrosine side-chain. Benzhydryl, tetralinyl ...
Utility of CT Scan and CA 19-9 in Predicting Non –Resectability in Malignant Obstructive Jaundice.
(University of Nairobi, 2014)
Background: Most patients with malignant obstructive jaundice (MOJ) present with non-resectable disease. Non curative laparotomy has been associated with adverse outcome. There is need to predict non-resectable disease ...
