14	For-to complements in Appalachian English Wade-Woolley, Lesly A. (Lesly Ann) January 1989 (has links) This thesis investigates the phenomenon of for-to complements in several dialects, focusing primarily on Appalachian English, though Belfast English and Ottawa Valley English are also examined. Following Chomsky's Government and Binding theory, we develop an analysis of for-to that predicts the distribution of for-to complements based on the requirements of Case, and the varieties of licit movement of features allowed by each dialect. To do this, we propose a Revised Case Filter which requires functional categories bearing Case features to discharge Case. We also show that the features of functional categories can move either by head movement (allowing movement of to into for) or by feature transmission (allowing for to move into to). / Each of these mechanisms generates a specific range of well-formed for-to complements; the distribution of these complements can be predicted by the ways in which the dialects allow features to move. Appalachian English and Ottawa Valley English allow head movement of features only, while Belfast English allows features to move via head movement and feature transmission. Thus for-to complements are more wide-spread in Belfast English than in the other for-to dialects. Standard English, which does not allow features to move unless they are accompanied by lexical material, does not exhibit for-to complements at all.

16	Evaluating organic compound sorption to several materials to assess their potential as amendments to improve in-situ capping of contaminated sediments Dunlap, Patrick John 08 July 2011 (has links) Contaminated sediments represent a common environmental problem because they can sequester large quantities of contaminants which can remain long after the source of pollution has been removed. From the sediment these hazardous compounds are released into the sediment porewater where it can partition into organisms in the sediment and bioaccumulate up the food web; leading to an ecological and human health concern. The objective of this work is to investigate an emerging option in contaminated sediment remediation; specifically an option for in-situ treatment known as active capping. Conventional capping uses clean sediment or sands to separate contaminated sediment from overlying water and biota. Active capping is the use of a sorptive amendment to such a cap to improve its effectiveness. This work focuses on granular materials as direct amendments to conventional caps including; granular activated carbon (GAC), iron/palladium amended GAC, alumina pillared clay, rice husk char, and organically modified clays. All materials were investigated in batch sorption tests of benzene, chlorobenzene, and naphthalene in DI water. Additionally porewaters from three sites were extruded and the concentrations of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were measured. At Manistique Harbor and Ottawa River PCBs were identified as the primary contaminant of concern while PAHs were the contaminant of concern at the Grand Calumet River. At these sites a solvent extraction method was used to analyze the sediment concentrations of the contaminants of concern. From the former batch tests activated carbon and a commercially available organoclay were chosen for further investigation. This includes PAHs in batch sorption tests using extruded sediment porewater to investigate matrix effects, and PCB sorption in distilled water. / text Sediment Contaminated sediments Remediation Sediment capping Polynuclear aromatic hydrocarbons PAHs Polychlorinated biphenyls PCBs Activated carbon Organoclay Sorption Clays Ottawa River Rivers Québec(Province) Ontario Mainstique harbor Great Lakes Illinois Indiana Grand Calumet River Michigan
