The purpose of this dissertation were threefold: (1) to develop a taphonomically-based facies (taphofacies) model for a classic, modern carbonate system, the south Florida shelf; (2) to compare and contrast the south Florida taphofacies model to the only other published modern carbonate taphofacies model, that of Parsons (1992) study of the northeastern Caribbean; (3) to compare and contrast a taphofacies model developed from the total mollusc assemblage (pooled sample approach) to models that only evaluate taphonomic changes within a single taxon as it occurs in different environments.
"The effects of various technical and economic parameters on LMFBR deployment plans have been studied to assess the best future mix of light water reactors and fast breeder reactors which will result in minimum cumulative nuclear generating costs discounted to the year 1985. Projected growth in domestic nuclear generating capacity was taken from various predictions [19, 20, 21], and the future domestic nuclear generating capacity was assumed to consist only of light water reactors and liquid metal cooled fast breeder reactors. Technical characteristics representing the two reactor types were taken as fixed, typical values for this study. The light water reactor characteristics represent a composite between PWRs and BWRs, whereas the most recent follow-on design was used as the reference for LMFBRs. Annual domestic power generation costs are calculated as a function of the installed capacity of both light water and fast breeder reactors in each particular year, the unit costs of each reactor type, the load factor, plutonium requirements, plutonium price and discount rate, and other factors. The cumulative nuclear generating costs are then computed as the sum of the discounted annual costs."
This dissertation is divided into four parts consisting of (1) an introduction to stagewise processes; (2) a summary of investigations appearing in the literature; (3) the detailed application of finite calculus to the stagewise operations of extraction, gas absorption and fractionation; and (4) an appendix containing the elements of the finite calculus and a few numerical solutions of problems presented in part (3).
In recent years, the spectrum of stress phenomena, ranging from the tragic to the mundane, has received a great deal of attention in the research literature. Research has found that exposure to a broad range of stress phenomena increases the risk for subsequent psychopathology (Kanner, Coyne, Schaefer, & Lazarus, 1981; Lewinsohn, Mermelstein, Alexander & MacPhillamy, 1985). The assumption that stress phenomena vary along a continuum from mild to severe underlies much of this research (Dohrenwend & Dohrenwend, 1978). Trauma has been understood to constitute the class labelled severe, life event stress (LES) the moderate, and daily hassles (DH) the mild. In empirical studies, these classes have thus been assumed to vary in terms of degree (i.e., quantity) rather than in terms of qualitative differences.
