This project seeks to give Stephen King and Pet Sematary full consideration through applying a multi-faceted ecocritical approach to a novel so clearly founded on the relationship between the land and its inhabitants. Through my analysis of the environment’s role in Pet Sematary, I will engage with important questions asked by both Historical and New Materialists in order to examine as completely as possible the relationship between Indigenous peoples and colonist conceptions of property, land use, and nonhuman agency present in the pages. Study of this sort engages in a critique of settler colonial ideals through a thorough examination of one of popular culture’s most successful and apparently errant offenders of intentional appropriation of Indigenous belief. Ultimately, this project seeks to reclaim not only Pet Sematary or King’s oeuvre, but the horror genre more broadly. Given the genre’s affordances for critiquing material histories, this project asserts horror’s utility for the development of new understandings of old fears and particularly as a means of asserting nonhuman agency. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

The object of this investigation was to determine, if possible, whether or not the magnesium ion concentration in the backfill has a significant effect upon the current efficiency of a pure magnesium anode when used to protect a steel cathode. Accordinging to H.A. Robinson, there should normally be no effect, but he indicated that there is room for doubt in some cases. It may be concluded, from the results obtained in this experimental work, that the current efficiency of magnesium anodes, when used as cathodic protectors of steel, is generally unaffected by changes in the concentration of magnesium sulfate in the backfill. It may be further stated that the presence of manganese ion also has no effect upon the current efficiency. The results indicate the possibility that current efficiency is appreciably affected by changes in the current density at the anode. It is suggested that further work be done in the study of this effect. It is further suggested that a wide variety of backfill conditions, for example, soils of different pH, be used in conjunction with this study. / M.S.

The silicone (organosilicon) polymere are a new and remarkable development of the chemical industry, Filling the void between organic and inorganic products, they find a great variety ef uses where their outstanding properties of heat and moisture resistance, general chemical inertness, and high electrical resistance can be applied. They are available as fluid for hydraulic and other uses, lubricants and greases, electrical sealing compounds, resins, and elastomers. Same of the intermediate compounds formed in the manufacture of these final products have also found uses. Organic compounds of silicon have been known and studied for over one hundred years, nearly all of the early study, however, was done on the chemical and physical properties of the monomers and low polymers and until very recently little was accomplished toward the practical application of this type of compound. In the United States, about 1935, impetus was furnished to research on the silicones by the need for a material suitable for binders, varnishes, and adhesives for newly-developed glass fabrics to be used in electrical insulation. The silicones are structurally analogous to glass and therefore seemed a likely starting point for the search. The monomers and low polymers are unsatisfactory and there were finally developed high polymers which proved to have outstanding heat moisture resisting properties, in addition to the desirable qualities for electrical insulation. Since then research on silicones has progressed rapidly. The number of new products developed has created a demand that has far outstripped commercial production, begun in 1943. All efforts are now being directed toward finding better commercial methods of production as present methods are expensive and relatively difficult to control. This seems to be particularly true of the initial step in silicone production, i.e., that of making the intermediate organochlorosilanes. The purpose of this investigation is to develop a process for the production of phenylchlorosilanes by the phenyl substitution of silicon tetrachloride at high temperatures. / Master of Science

The purpose of this investigation was to obtain definite quantitative data on the optimum conditions for the production of ethylene oxide by the catalytic vapor phase oxidation of ethylene. This data was to cover the effects of temperature, ethylene concentration, and velocity of flow through the catalyst bed. The catalyst chosen was metallic silver, known to be effective in promoting the reaction. The experimental data obtained was to be used in making preliminary engineering studies on the design of a commercial plant for the production of ethylene glycol by first forming ethylene oxide and then hydrolyzing it to the glycol. The reactor used in oxidizing ethylene to the oxide consisted of an iron reactor tube 0.824 inches in diameter and 11.7 inches long, surrounded by a diphenylamine constant temperature bath. The tube was filled to a depth of 10 inches with the metallic silver catalyst. Rates of flow of the air and ethylene streams were controlled by means of needle valves and indicated by water filled manometers. The reactant gas mixture was pre-heated prior to passage through the reactor tube. A series of runs was made to determine the effect of ethylene concentration on the oxidation reaction. The temperature was held at approximately 260°C. and the gas flow rate was set at 25 liters/cm.²/hr. for each run. The ethylene concentration was varied from one per cent to 9.8 per cent. It was found that the highest yield of the oxide was obtained with an ethylene concentration of one per cent. An increase in the ethylene concentration was found to result in lower yields of the oxide. The effect on ethylene oxide production of the rate of gas flow through the catalyst bed was deter:nined by making three series of runs at gas flow rates of 12.5, 25 and 50 liters/cm²/hr. respectively. Temperatures were varied from 200°C. to 265°C., while the ethylene concentration was held at 2.2 per cent. It was found 2 that a rate of flow of 25 liters/cm. /hr. gave uniformly highest yields of ethylene oxide. A rate of flow of 50 liters/cm²/hr. gave the lowest yields, while a gas flow rate of 12.5 liters/cm²/hr. gave yields intermediate between the other two rates. The results of a series of runs made for the purpose of determining the effect of temperature on the yield of ethylene oxide indicated that the yield of oxide increased as the temperature was increased from 200°C. to 240°C. As the temperature was further increased from 240°C. to 265°C., the yield of ethylene oxide decreased with the increasing temperatures. The optimum temperature for the reaction was found to be 240°C. for gas flow rates of 12.5, 25 and 50 liters/cm²/hr. through the catalyst bed. The commercial plant, designed on the basis of the data obtained, is designed to produce 6,451,352 pounds of antifreeze mixture per year. The capital investment required is $3,900,054. The gross annual income would be $967,703 on the basis of a selling price of $0.15 per pound for the antifreeze mixture. The yearly cost of production would be $883,256, giving a net yearly income of $84,447. / M.S.

Les romans City of Glass et Leviathan de l'auteur états-unien Paul Auster mettent en scène deux types d'espace bien distincts en perpétuelle tension. Le lieu clos de l'écriture, refuge privilégié pour les écrivains, précède l'espace ouvert urbain dans lequel les protagonistes choisissent éventuellement de se propulser, et lui fait face. À l'intérieur de ce nouvel espace comparable à un labyrinthe, les écrivains connaissent une transformation marquée et irréversible. L'objectif de ce mémoire est de révéler comment la dichotomie des espaces permet d'expliquer la mutation subie par les personnages. L'originalité du projet vient du fait qu'il s'agit probablement de la première étude à faire un lien entre la configuration spatiale des romans d'Auster et le processus de métamorphose et de dégradation traversé par les personnages. Il s'agit aussi de la première recherche à qualifier la chute et le destin funeste des protagonistes, pourtant largement abordés par les critiques, de devenir-monstre. Les notions d'une herméneutique des espaces romanesques servent de cadre théorique afin d'évaluer la construction spatiale des œuvres, élément clé de la problématique de cette analyse. Cette première partie de l'étude se voit prolongée et renforcée par la théorie de la déterritorialisation, puisque les personnages passent d'un contexte spatial à un autre, ainsi que par une observation de la crise existentielle vécue par les protagonistes pendant leur aventure. Le recours au mythe grec de Thésée en tant que référence pour saisir les motifs associés à l'imaginaire du labyrinthe permet également de poser un regard mieux orienté sur le sort qui attend les héros dans le dédale austérien. Dédoublement identitaire, perte du statut de sujet, hybridité, altération de la connaissance de soi et métamorphose en monstre sont autant de répercussions qui attendent les personnages délaissant leur pièce d'écriture pour s'engager dans l'hostile labyrinthe. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Paul Auster, espace romanesque, écrivain, labyrinthe, métamorphose, monstre, City of Glass, Leviathan.
