An investigation of buoyancy driven natural convection in a cylindrical enclosure.
(University of Nairobi, 2015-04)An investigation of heat transfer was done in a cylindrical enclosure. The effects of varying Reynolds Number, Prandtl number, Froude number, and Euler number on the temperature and velocity was investigated. In the study, ... -
Investigation of flow dynamics of porous clinkers in a ball mill using technitium-99m as a radiotracer.
(University of Nairobi, 2019)A radiotracer investigation was carried out in a ball mill of a cement plant in Kenya. Residence time distribution (RTD) of raw feed to the mill was measured using Technetium-99m adsorbed on the clinkers as a radiotracer. ... -

(University of Nairobi,, 2013) -
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 ... -
Investigation of pollutants, determination of physico-chemical characteristics of the Nairobi river and remediation of some toxic heavy metals using fish bones
(University of NairobiChemistry, 2010)A Study was conducted to determine the level of pollution in the Nairobi River. The study covered four sampling sites located along the river, stretching from upstream at Ondiri swamp then moving to Museum Hill Bridge ... -
Investigation of Radiative Characteristics of the Kenyan Atmosphere due to Aerosols Using Sun Spectrophotometry Measurements and the COART Model
(Taiwan Association for Aerosol ResearchSchool of Physical Sciences, 2013)Variations in the radiative characteristics of aerosols can be used to quantify their effects on climate. This study evaluated the temporal-spatial variability of aerosol radiative characteristics at λ = 440 nm, λ = 675 ... -
Investigation of some medicinal plants traditionally used for treatment of malaria in Kenya as potential sources of antimalarial drugs.
(University of NairobiCollege of biological and physical science, 2011-03)Malaria is a major public health problem in many tropical and subtropical countries and the burden of this disease is getting worse, mainly due to the increasing resistance of Plasmodium falciparum against the widely ... -
Investigation of the Effect of film Thickness on the Optical Properties of Amorphous Se 85-xTe15Sbx
(University of Nairobi, 2014)Amorphous thin films of Se85-xTe15Sbx (x = 0.0, 0.5, 2.5, and 5.0 at. %) deposited by flash evaporation technique, have been investigated in the wavelength range of 500nm-3000nm. It is found that the effect of increasing ... -
Investigation of the Electrocatalytic Properties of Spherical Palladium Nanoparticles and Palladium (100) Iridium Bimetallic Nanocomposites Towards Ammonia Electrooxidation on …
(University of Nairobi, 2015)The electrocatalytic properties of cubic palladium-iridium {Pd(100)Ir} bimetallic nanocomposite and spherical nanoparticles {Pd NPs} towards the electrochemical oxidation of ammonia were investigated in sodium hydroxide ... -
An Investigation of the Equatorial Orographic–Dynamic Mechanism
(University of Nairobi, 1985)A barotropic model over an equatorial beta-plane is used to investigate the response when a uniform zonal current crosses an isolated hypothetical mountain centered at the equator. The bounded derivative initialization ... -
Investigation of the impact of salt and sand harvesting activities on the Timboni well field, Gongoni, Malindi District, Kenya
(2000)The area studied is a north-south oriented, V-shaped, clayey lagoonal depression bordered by Pleistocene sands on the west and Recent dune sands on the east. The freshwater aquifer in the area is the main source of potable ... -
An investigation of the repeatability of calibration factors in gamma-ray spectrometry of geological materials
(Department of Physics, University of Nairobi, 2004)A NaI(Tl)-based gamma spectrometer for the analysis of geological materials was calibrated using the IAEA reference materials RGU-1, RGTH-1 and RGK-1. To simulate typical geological samples, two additional standards were ... -
An investigation of the structure beneath Magadi area in Southern Kenya Rift using gravimetric data
(School of Physical Sciences, 2012)Magadi area is located in the southern part of the Kenyan rift, an active continental rift that is part of the East African Rift system. Local seismic activity monitored previously around Lake Magadi revealed an earthquake ... -
An investigation of the transport and dispersion of atmospheric pollutants over east Africa during the Ol doinyo lengai volcanic eruption in July 2007 and march 2008
(2012)Explosive volcanic eruptions affect climate by injecting gases and aerosol particles into the troposphere and stratosphere. Only if the eruption cloud is rich in SO2 will the eruption produce a long-lived aerosol cloud, ... -
