Resurfacing Saturn's Satellites: Models Of Partial Differentiation And Expansion
(University of Nairobi, 1985-12)The faulting seen on the surfaces of Saturn's icy moons may have been caused either by external events, such as large impacts, or internal stresses caused by the expansion of the moons as long-lived radionuclides produced ... -
Retention Behavior of Metal Particle Dispersions in Aqueous and Nonaqueous Carriers in Thermal Field-Flow Fractionation
(Department of Chemistry, 2003-01)Until quite recently, theories on thermophoresis of particles predicted very low thermophoretic velocities of metal particles in liquids. This prediction was based on the understanding that the very high thermal conductivities ... -
Retrieval of aerosol optical depth over ecologically stressed East African land surfaces from top of atmosphere radiance utilizing the aerosol free vegetation index.
(2015)Traditional satellite based AOD retrieval techniques with a coarse resolution such as collection 5 hardly provides a high spatial detail suitable for accurate AOD retrieval particularly over the ecologically stressed sites ... -
Reuse of samples: ethical issues encountered by two institutional ethics review committees in Kenya.
(University of NairobiDepartment of Chemistry, 2005-10)There is growing concern about the reuse and exploitation of biological materials (human tissues) for use in research worldwide. Most discussions about samples have taken place in developed countries, where genetic ... -
Reverse logistics and competitive advantage: the mediating effect of operational performance among manufacturing firms in Kenya
(European Scientific Journal, 2020-07-31)Today globally, countries and manufacturing entities alike are concerned with environmental sustainability apart from economic gains. Implementation of reverse logistics programs has been contemplated as a feasible alternative ... -
