Swelling of Polymer-Oligomer Particles

Abstract: A quantitative study of the swelling capacity of polymer-oligomer particles, and the rate of transport of slightly water soluble compound 1, e.g. chlorobenzene, from bulk phase to the particles has been carried out. A much higher swelling capacity was attained when compound 1 was subdivided (before it was added to the swelling experiments) than when it was added as a bulk at the same experimental conditions. It is shown that the increased swelling capacity when compound 1 is subdiv...

Geophysical Investigation Of Geothermal Potential Of The Gilgil Area, Nakuru County, Kenya Using Gravity Method

ABSTRACT In this study, gravity survey method was used to investigate the geothermal potential field in Gilgil area, Nakuru County, Kenya. No previous geophysical study has been done in Gilgil area. Gilgil area is volcanic and gravity survey in volcanic regions has shown that it gives useful information about the density changes within the Earth’s subsurface associated with the heat source. Gravity highs are related to centres of volcanism, faults and geothermal activity. The discovery of g...

Natural Radioactivity Hazards Of Building Bricks Fabricated From Clay Soil Of Bomet District, Bomet County, Kenya

ABSTRACT Primordial radionuclides in building materials are one of the major sources of radiation hazard in dwellings. Clay bricks are mainly used for the construction of dwellings in Bomet district, Bomet County, Kenya. Therefore, knowledge of the presence of natural radioactivity in these materials is of great importance in order to assess the radiological hazards associated with them. In this context, specific activities of 226Ra, 232Th and 40K were measured in brick samples collected from...
