The Radford area consists of approximately 190 square miles in the Appalachian Valley portion of Montgomery and Pulaski counties, Virginia. All of it is underlain with sedimentary rocks ranging from Early Cambrian to Early Mississippian in age, and having an aggregate thickness of at least 12,000 feet. These rock units do not represent a complete sedimentary sequence in this part of the Appalachian geosyncline because much of the Radford area is covered by three overthrust sheets which conceal formations that would otherwise be exposed in the area. The greatest movement along these low-angle thrust faults appears to be that of the Pulaski thrust sheet. It has a horizontal displacement of at least eight miles and a minimum stratigraphic separation of 9000 feet. The Pulaski thrust sheet has been further complicated by three high-angle thrust faults which have contributed to the formation of three “windows” southeast of Redford. Two klippen that are associated with the Blue Ridge thrusts occur in the southeastern corner of the area. / Master of Science

This thesis is an examination of sound and lived space in Janet Cardiff's audio walks, Missing Voice, and Conspiracy Theory. Its aim is to contextualize Cardiff's project in terms of how it reverses the logic of the conventional museum audio guide; taking the user on an unexpected tour of the back spaces, and by providing an audio track of soundscapes which are not about the art exhibition but rather point to the social relations constituted in each audio walk environment. Paradoxically, it is the non-synchronous elements of Cardiff's audio walks that point to the embedded nature of expectations produced by body technique. It is through the disjunction of the experiential moment between sensorial input and our awareness of it (an incongruent relationship between what is expected and what is experienced) that, Gilles Deleuze's concept of the pre-individual is actualized for the lived body. The actualized pre-individual lies at the core of an analysis, of how Cardiff's audio walk transgresses the limits of a single art work and reopens living as an emergence for the interconnectedness of the actual-virtual.

James Dickey's work as an artist grows out of the way he feels about life, and about the world of art. He believes that aesthetic experience can revitilize the reader, that it can give him a new vision. And because of the new vision the artist and the reader are united. The poem, therefore, becomes a very alive, vibrant medium. And during his poetic career James Dickey explores the possibility of poetry as a statement. He is never afraid to push a poem to the limits of experience. The result is sometimes a strange, and grotesque work of art. However, in his best moments James Dickey is capable of loading the poem with intense energy. And it is this energy which he hopes to transfer to the reader so that the reader can see the world with new eyes. / Arts, Faculty of / English, Department of / Graduate

It was stated in the introduction that the purpose of this project was to design and construct a sunlight integrator which would have wide intensity range, reliability under normal operating conditions, and moderate cost. If the minimum sensitivity for the first filter is arbitrarily chosen as one-tenth the dark counting period, which is in excess of three hundred seconds, the minimum detectable light intensity would be: .00858/30 = .000286 lumen per cm². This is equivalent to an intensity of .256 foot-candle for a 30 second counting period. / Master of Science

The section of this report devoted to the control of slides serves to illustrate the more typical situation of a movement, that is not subject to a theoretical analysis. The great majority of slides that occur in natural ground pass through complex soil stratifications that do not permit the simplifying assumptions needed for the various methods of mathematical and graphical analysis, In these cases, the procedures for the control and stabilization of the moving material depend exclusively on the characteristics of the particular location, Each slide is a separate problem whose solution is not necessarily similar to any other. The control section of this report has presented a summary of the various methods for the field control of slides that may he used, The choice of the applicable method is made only after extensive study of the nature of the particular slide, The more common control procedures have been illustrated by reference to the case histories of actual slides that have been successfully controlled. / Master of Science

Sulfur dioxide and 1,3-butadiene react to form a five-membered cyclic unsaturated sulfone. the 2,5-dihydrothiophene 1,1-dioxide (I). When treated with a base, I will isomerize to form the 2,3-dihydrothiophene 1,1- dioxide (II). The known procedures for the preparation of I and II have been improved. [see document for image of chemical structures] The 2,5-dihydrothiophene 1,1-dioxide (I) is the parent member of a large group of five-membered cyclic β-sulfones while the 2,3-dihydrothiophene 1,1-dioxide (II) is the parent member of the corresponding α-sulfones. Structurally, I contains a carbon-carbon double bond, a sulfone group and two α-methylene groups while II only has one α-methylene group but its carbon-carbon double bond is conjugated with the sulfone group. It is of considerable interest to study the chemical reactions of these two polyfunctional molecules to gain some information concerning the influence of the functional groups upon each other. Of further interest would be to compare the reactions of I and II since differences in chemical properties are to be expected since the α-sulfones have the double bond conjugated with the sulfone group while the β-sulfones do not. Bromine adds readily to I in aprotic media to give the 3,4-dibromotetrahydrothiophene 1,1-dioxide (V). The addition of bromine to II only occurs in a water solution to give the 2,3-dibromotetrahydrothiophene 1,1-dioxide (VII). The total lack of evidence of the addition of hydrogen halides to I or II was not expected. The electrophilic attack is hindered by the presence of the sulfone group. Free radical reactions using N-bromosuccinimide and 1,3-dibromo-5,5-dimethylhydantoin were employed with I and II. The expected allylic substitution of bromine in I at the 2 or 5 position and in II at the 3 position was not obtained but rather addition to the double bond of I and II occurred. The dehydrobromination reaction of 3,4-dibromo-tetrahydrothiophene 1,1-dioxide (V) has been improved to give better yields of the 3-bromo-2,3-dihydrothiophene 1,1- dioxide (XIII). A new compound, the 5-bromo-2,3-dihydrothiophene 1,1-dioxide (XVIIc), has been obtained from the dehydrobromination of the 2,3-dibromo-tetrahydrothiophene 1,1-dioxide (VII). The 3-bromo, 3-chloro and the 3-iodo-2,3-dihydrothiophene 1,1-dioxides were prepared through a series of reactions, the letter two for the first time. The 3-iodo-2,3-dihydrothiophene 1,1-dioxide (XIX) was prepared by treating the 3-bromo-2,3-dihydrothiophene 1,1- dioxide (XIII) with sodium iodide in acetone. The 3-chloro-2,3-dihydrothiophene 1,1-dioxide (XX) in turn was prepared by reacting the 3-iodo-2,3-dihydrothiophene 1,1-dioxide (XIX) with mercuric chloride in absolute ethanol. The infrared spectra of the above compounds were compared. Since the alpha hydrogens are acidic in the cyclic unsaturated sulfones, a thorough study of Grignard reagents with the 2,5-dihydrothiophene 1,1-dioxide (I) was made. A compound, believed to be a sulfinic anhydride, was obtained from the action of the 2,5-dihydrothiophene 1,1-dioxide (I) on ethylmagnesium bromide. Some evidence in support of this sulfinic anhydride is offered. A mechanism for the Grignard reactions is proposed from the data obtained. There was no evidence for condensation, alkylation or acylation reactions with the isomeric dihydrothiophene 1,1- dioxides. On the basis of the reactions studied, a clearer picture of the resonance structure of the 2,5-dihydrothiophene 1,1-dioxide (I) is obtained. / Ph. D.
