Thermal Conductivity of Particulate Insulators: Effect of Particle Size Distribution, Moisture Content and Binders
(School of Physical Sciences, 1996) -
Thermal cycling behaviour in Kenyan kaolinite thermal insulators
(Department of Physics, University of Nairobi, 2000)The thermal shock and thermal fatigue behaviour of a Kenyan kaolinite clay used in firewood jikos and in kiln linings has been studied. The thermal shock R parameters have been measured for the material. Also measured ... -
Thermal effects on plasma Dispersion Relation
(University of NairobiDepartment of Physics, 1995)Abstract Not available -
Thermal fatigue behaviour of a Kenyan kaolinite clay
(1999)The thermal fatigue resistance for a Kaolinite clay-based refractory used for then1lfl1 insulation in local (Kenyan) firewood cooking stoves has been studied by subjecting them to a water quench to predict their values ... -

Thermal shock behaviour of a kaolinte refractory prepared using a natural organic binder
(SpringerDepartment of Physics, University of Nairobi, 2006)The thermal shock resistance of a kaolinite-based refractory prepared with a binder derived from a plant (corchorus olitorius) was investigated. Thermal shock tests employing water-quenching technique were performed at ... -
Thermal Shock Resistance of a Kyanite-Based (Aluminosilicate) Ceramic
(Society for Experimental MechanicsSchool of Physical Sciences, 2010)This paper presents the results of a combined experimental and theoretical study of microstructure and thermal shock resistance of an aluminosilicate ceramic. Shock-induced crack growth is studied in sintered ... -

Thermodynamic and kinetic aspects of formation of bauxites
(University of Nairobi, 1987)Experiments in which cleavage nepheline samples were reacted with aqueous solutions at fixed pH's and temperature were carried out in the laboratory. The chemistry of the solution as a function of time was monitored, as ... -
Thermolysis of .alpha.-azido sulfides, sulfoxides, and sulfones: dependence of mechanism on oxidation state of sulfur
(Department of Chemistry, 1981) -
Thermophoresis of Metal Particles in a Liquid.", J
(Department of Chemistry, 1995)Using a theory of phoresis of solid particles in a liquid, the thermophoresis of metal particles is theoretically examined. It is shown that, taking into account a transverse temperature distribution around a particle, ... -
Thermoregulation and oxygen consumption in Kirk's dik-dik (Madoqua kirkii) at ambient temperatures of 10–45°C
(University of Nairobi, 1979-06)1. 1. Thermoregulatory and metabolic responses of dik-dik (Madoqua kirkii) were measured over an ambient temperature (Ta) range of 10–45°C. 2. 2. The lower critical temperature was estimated at Ta 25°C. 3. ... -
The thermostability of haemoglobins from the hot-spring fish, Oreochromis alcalicus grahami: Comparisons with antarctic and temperate species
(University of Nairobi, 1994)1. The thermostability of haemoglobin was measure in three species of fish living at different environmental temperatures (ET). 2. The time (min) for 50% denaturation (T1/2d) of the haemoglobin at 2 mg ml-1 in 50 ... -
Thermostable Biocatalytic Films of Enzymes and Polylysine on Electrodes and Nanoparticles in Microemulsions
(American Chemical SocietyDepartment of Chemistry, University of Nairobi, Nairobi, 2008)Microemulsions of oil, water and surfactant were evaluated as media for biocatalysis at high temperatures employing films of polylysine (PLL) and the enzymes horseradish peroxidase (HRP), soybean peroxidase (SBP) and the ... -
Thermostable Peroxidase−Polylysine Films for Biocatalysis at 90 °C
(Department of Pharmacology, University of Connecticut Health Center, Farmington, ConnecticuDepartment of Chemistry, University of Nairobi, NairobiDepartment of Chemistry and Institute of Materials Science, 55 North Eagleville Road, University of Connecticut, Storrs, Connecticut 06269, 2007)ross-linked films of poly(l-lysine) (PLL) and enzymes covalently linked to surfaces provided remarkable thermostability, enabling biocatalysis at 90 °C. Soret spectra, circular dichroism, and voltammetry showed that PLL ... -
