Positron-Impact Excitation Of The Lowest Autoionizing State In Rubidium Atom Using Distorted Wave Method

 ABSTRACTMany calculations on atomic collisions and scattering processes have been performed on electronimpact excitation of the lowest autoionizing state of rubidium, but not much attempt has beenmade with positron impact which is of equally fundamental importance and is receiving attentionnowadays with the availability of improved positron beam experiments. So, in this study, totalcross-sections, differential cross-sections, lambda parameter, R parameter and the alignmentparam...

Mechanical Properties And Thermal Degradation Of Bitumen-Acacia Sap Composites

ABSTRACTThe rapid increase in traffic intensity, axle loading, rigorous climatic changes and commercial road transport continues to impose severe demands of load and environment on the highway system. Bitumen mostly used as a binder for road construction, waterproofing agent, coating, and insulation among others has poor mechanical and thermal properties. Different synthetic binder modifies that are being used to improved performance lead to environmental pollution during disposal. Therefore,...

Positron Impact Excitation For The Lowest Autoionizing State Of Cesium Using The Distorted Wave Method

ABSTRACTAtomic collision cross sections are of interest because they can show the collision dynamics involved in the scattering process. There has been an upsurge in interest on positron collision processes due to recent advancement in positron beam experiments. In these studies, alkali metal atoms receive preference due to their simple electronic structure and spectra. We have calculated differential cross-sections, integral cross-sections, lambda (λ) parameter and the alignment parameter (...

Magnetic Studies Of Iron Ore Mineral Deposits In Mbeu Area, Meru County, Kenya

ABSTRACTIron industry in Kenya is dependent on imported raw materials. Local deposits of iron ore have been identified at various places in the country but not much has been done to determine whether the deposits are viable in quantity and quality for commercial exploitation. The location and delineation of the iron deposits and formation in the Mbeu area appraises the potential of such mineralization. Ground magnetic survey of Mbeu area was conducted to investigate subsurface geology on the ...

Determination Of Antimicrobial Resistance Of Escherichia Coli Isolated From Rastrineobola Argentea And Water Samples From Lake Victoria - Kenya

ABSTRACTMany strains of Escherichia coli can be pathogenic leading to diarrheal diseases. The occurrence of antimicrobial resistant bacteria is increasing in aquatic environments infecting fish which are later consumed by humans when not well cooked posing a major problem in the management of bacterial infections. Rastrineobola argentea is food for many people living around Lake Victoria due to its nutritive value and high protein content. Sun dried R. argentea retailed in Kisumu city...
