The purpose of this investigation was to study the effects of activated sludge aerobic digestion on the subsequent performance of a centrifuge. Two runs, utilizing two, 55 gallon barrels as digesters per run, were conducted using detention periods of 15 and 14 days, for run #1 and #2, respectively. Besides centrifugation, various water quality parameters were monitored during the two digestion runs. Results of this investigation indicated that the aerobic digestion process is suitable for waste activated sludge stabilization. Significant total and volatile solids reductions in conjunction with consistent supernatant COD and BOD₅ reductions were noted. However, prolonged periods of aeration caused a decrease in both the filterability and the centrifugation performances. Both reached their optimum peaks within the first 5 days of aeration and then gradually declined. This seems to indicate that once a sludge reaches the endogenous respiration state that sludge handling becomes much more difficult. The improvement in centrifugation efficiency that occurred during the early stages of aerobic digestion was not enough to justify the expense of aerobic digestion prior to centrifugation. / Master of Science

The body of work that we usually call science fiction has a rich and often ambivalent history. Its humble roots in pulp magazines and dime novels contributed to an image of disposable, low brow writing, unworthy of the title “literature”. Those incipient assumptions, which still remain, became themselves ways of establishing what we now call a genre. In part, due to this uncomfortable image of a bastardized literature, the history of science fiction criticism frequently reflected a sense of discomfort with the way this genre was perceived. As a result, there have been many readings that attempt to lift the texts under scrutiny from a perception of polluted beginnings. While this impetus has produced some of the most essential science fiction criticism, it has also stirred a level of controversy by inevitably inscribing a canon. In recent years, we have begun to encounter a frontal discussion both on the literature itself and on the significance of these readings. These include further connections not only with theory, but also with their pulp legacy. In this regard, this study attempts to link utopia to science fiction, particularly in relation to how the roots of science fiction became enablers for a thoroughly utopian-driven genre. For this purpose, three authors are analysed: Frank Herbert, Isaac Asimov and Philip K. Dick. Their prominence has garnered an enormous amount of study, perhaps the biggest of any other author. Tied to this is the fact that all three have a background in writing for pulps and their work has become iconic on its own. Therefore, it seems productive to analyse the threads that run through their work, the links their writing might have to each other and to external input but, most of all, how utopia may be a fitting way to interpret the science fictional impetus.

This thesis is a critical study of the theme of shame in Shakespeare. The first chapter defines the senses in which shame is used. Chapter Two analyses the workings of shame in pre-renaissance literature. The argument sets aside the increasingly discredited shame-culture versus guilt-culture antithesis still often applied to classical and Christian Europe; then classical and Christian shame are compared. Chapter Three focuses on shame in the English Renaissance, with illustrations from Spenser, Marlowe, Jonson, and Milton. Attention is also paid to the cultural context, for instance, to the shaming sanctions employed by the church courts. It is argued that, paradoxically, the humanist aspirations of this period made men and women more vulnerable to shame: more aware of falling short of ideals and open to disappointment and the reproach of self and others. The fourth chapter is an introductory account of Shakespearean shame; examples are drawn from the plays and poems preceding the period of the major tragedies, circa. 1602-9. This lays the groundwork, both conceptually and in terms of Shakespeare's development, for the main part of the thesis, Part Two, which offers detailed readings of Hamlet, Othello, King Lear, Antony and Cleopatra, and Coriolanus. In Each case, a consideration of the theme of shame illuminates the text in question in new ways. For example, and exploration of shame in Hamlet uncovers a neglected spiritual dimension; and it is argued that, despite critical tradition, shame, rather than jealousy, is the key to Othello, and that Antony and Cleopatra establishes the attraction and limitation of shamelessness. The last Chapter describes Shakespeare's distinctive and ultimately Christian vision of shame. In a tail-piece it is suggested that this account of Shakespearean shame casts an intriguing light on a little-known interpretation of Shakespeare's last days by the historian E.R.C. Brinkworth.

In the vicinity of Hoges Store, Giles County, Virginia, certain portions of the Five Oaks and Elway limestones containing more than 97 per cent calcium carbonate crop out near the event of the Thessalia anticline and John's Creek syncline and underlie an extensive area where dips probably are less than 20 degrees. Locally, part of the Benbolt, Gratton, and Witten are also high-calcium limestone. Sites for core drilling and possible subsequent mining or quarrying are inferred from study of exposed rocks, by chemical analyses of channel samples of selected zones of high-calcium limestones and by detailed geologic mapping. The report includes columnar sections showing the character and thickness of the limestone units. One large deposit of chemical-grade limestones was found about 1.5 miles northeast of Hoges Store, which is believed to underlie a large area wherein dips of the mineable strata are less than 15 degree. The amount of recoverable stone is estimated to be 80 million tons. Suggested locations for core drilling are shown. An anticline, two synclines and an intricate structure are the structural features of the area of study. The major structural features of Giles County are delineated on a sketch map. / Master of Science
