The Paleoethnobotany Of Schwerdt (20ae127): An Early Fifteenth Century Encampment In The Lower Kalamazoo River Valley, Gregory R. Walz
The Paleoethnobotany Of Schwerdt (20ae127): An Early Fifteenth Century Encampment In The Lower Kalamazoo River Valley, Gregory R. Walz
Masters Theses
Carbonized macrobotanical remains from the Schwerdt Site, an Upper Mississippian sturgeon fishery in the Lower Kalamazoo River Valley are identified and analyzed in terms of their implications for localized subsistence-settlement systems operating during the Berrien Phase in southwestern Michigan. The exploitation of wild plant foods at this limited-activity, spring sturgeon fishery and the environmental composition of the site environs are reconstructed from their representation in flotation samples derived from excavated feature and midden contexts.
Botanical data indicate a strong wetland-aquatic orientation in plant procurement, with aquatic tubers being the primary plant resource exploited at the site. Data from several sites …
Anderson Localization Effects In The Light Transmitted Through A Rough Thin Metal Film, Naimah Mohd. Shafie
Anderson Localization Effects In The Light Transmitted Through A Rough Thin Metal Film, Naimah Mohd. Shafie
Masters Theses
The theory of Anderson localization is used to study transmission enhancements in the diffusely transmitted light through a rough thin metal film. These transmission enhancements arise due to phase coherent effects associated with Anderson localization of surface polaritons and are manifested as a well-defined peak in the angular distribution of the intensity of the diffuse component of the transmitted light for light moving opposite to the specularly reflected beam.
The dependence of the widths and heights of the localization related transmission peak is investigated with computer programming and calculations by McGurn and Maradudin (1989). The peak is found to depend …
