This thesis traces the origin and development of the " American School " of ethnology from the natural historical debate over the nature of hybridity and the definition of species between the naturalist John Bachman and the ethnologist Samuel George Morton to the posthumous management of Samuel Morton's reputation and authority by the physician and(More)
A model applying surfactant self-assembly theory and classical thermodynamics has been developed to aid in the prediction of solid surface cleaning by aqueous surfactant solutions. Information gained from a combination of surfactant self-assembly behavior and cleaning system parameters, such as oil species, surfactant type, temperature, alkalinity, and(More)
The present study investigates the change in the shape of oil droplets immersed in an ionic surfactant solution when the droplets are in contact with metal surfaces to which an electrical potential is applied. The three-phase system of aqueous solution-oil-steel was subjected to low-voltage electric potentials, which resulted in sometimes dramatic changes(More)
