Benthic Infaunal Community Formation In Dredged Areas In Hampton Roads, Virginia, Thomas Karl Duncan

Dissertations, Theses, and Masters Projects

The macrobenthic fauna in three dredged areas in Hampton Roads, Virginia was sampled for 14 months. Repopulation occurred very rapidly after the cessation of dredging, but the dominant species were generally not those previously recorded as mud-bottom dominants in the Hampton Roads area. The faunal changes through time somewhat agreed with those reported in classical successional sequences. This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.

Mechanics Of Beach Cusp Formation, Asbury H. Sallenger

Dissertations, Theses, and Masters Projects

Beach cusps are crescentic shoreline accumulations of unconsolidated sediment that are characterized by a quasi-equal longshore spacing. The processes controlling the development of the cuspate form and the spacing of cusps were investigated. Field measurements showed that the cuspate form was derived through erosion of beach ridges, The ridges oriented alongshore in the swash zone are characterized by quasi-equally spaced channels cut normal to the shoreline whose widths are much less than the channel spacing. The upwash flows up the front face of the ridge and ponds shoreward of the ridge crest. The ponded fluid returns seaward through the channels. …

Metal Promoted Reactions Of Enamino Ketones, Suhas Satchidanand Joshi

Masters Theses

The reaction of 4-amino-3-allyl-3-penten-2-one (7) with mercuric acetate in acetic acid was found to produce 4-amino-1-pentene (12) in 70% yield. The scope of this unusual cleavage reaction was investigated by systematic variation of substituents on the enamino ketone framework, the metal salt and the solvent. The presence of the allyl group was necessary for the reaction to produce compound 12.

Under a variety of conditions there was no evidence for cyclization of 7 to give heterocyclic compounds. Neither was there evidence for cyclization in reactions of 4-amino-3-penten-2-one with vinyl acetate in the presence of mercury (II) or thallium (III) salts …

Pesticide Effects In A Simulated Soil Ecosystem, Raymond J. Samp

Masters Theses

The screening of pesticides to determine which were most inhibitory to bacteria was accomplished by testing the effects of 10 pesticides on 9 different organisms using the disk assay method. Results showed that Gram positive bacteria were more sensitive to all pesticides tested than were the Gram negative bacteria. In addition, the hormone herbicides were found to be the most inhibitory to these bacteria and 2,4-D (2,4-dichlorophenoxyacetic acid), a hormone herbicide, was chosen for subsequent in vivo studies.

A soil perfusion apparatus was used to determine the effects of 2,4-D in a typical soil ecosystem. Bacterial plate counts and nutrient …

The Water Quality And Benthic Macroinvertebrate Fauna Of Lake Charleston, Coles County, Illinois, Paul Barding

Masters Theses

The benthic macroinvertebrate fauna and 15 water quality parameters for five sites on Lake Charleston, Coles County, Illinois were examined for 26 weeks from March 14 through September 5, 1974. None of the water quality parameters studied showed sufficient deviations at any particular area on the lake to merit demarcated water quality zonation. The lake, with its continuous mixing and shallow depth, represented a fairly stable and continuous environment. The benthic macroinvertebrate fauna was determined as fairly diverse and some indication of seasonal variation was apparent. No significant compositional variation over different areas of the lake was found, also indicating …

Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

Conodonts Of The Mecca Quarry Shale, Timothy Charles O'Neill

Masters Theses

Conodonts were found to be abundant in the Middle Pennsylvanian, Mecca Quarry Shale, Parke County, Indiana. Nine forms were identified in this black fissile shale from a locality along Montgomery Creek near the town of Mecca. These elements are: Hindeodella parva, Idiognathodus delacatus, Gondolella sp. a, Ozarkodina delacatula, Lonchodina clarki, Ligonodina typa, Lonchodus simplex, Metalonchodina bidentata, and Neoprioniodus conjunctus.

Ratios of elements to each other were determined and used to arrive at an idea of what conodont assemblages were present. At least three asemblages are presented; Scottognathus, Duboisella, and Illinella …

A Simulator For The Ibm 3705 Communications Controller, J. William Strider

Graduate Theses, Dissertations, and Problem Reports

This paper describes a computer program which was developed to simulate the IBM 3705 Communications Controller, using the IBM System/360 and System/370 computers. The architecture of the 3705 is discussed in some detail, and the structure of the simulator is described. Future enhancements to the present program are suggested, along with possible applications.

Paleontology Of Brackish-Water Faunas In Two Tongues Of The Cannonball Formation (Paleocene, Danian), Slope And Golden Valley Counties, Southwestern North Dakota, James B. Van Alstine

Theses and Dissertations

In June and July, 1972, four stratigraphic sections were mea sured and described in Slope and Golden Valley Counties, southwestern North Dakota. Within the sections, the Cannonball and Ludlow Formations are recognized. The Cannonball consists of two tongues in the upper part of the Ludlow (perhaps equivalent to the Lebo Member), separated stratigraphically by about 30 roof Ludlow. The U tongue (upper tongue in the study area) is up to 11. 7 m thick. The L tongue (lower tongue. in the study area) is up to 3.8 m thick. The Cannonball is composed mostly of mudstones and the Ludlow consists …

Three Papers In Mathematical Logic, Henry P. Miranda '74

Fenwick Scholar Program

Three papers were written in partial fulfillment of the requirements for the Fenwick Scholar Program 1973-1974:

An Algebraic Proof of the Completeness of Sentential Logic proves the completeness of sentential logic using concepts of Boolean structures.

Godel's Proof of the Incompleteness of Axiomatic Number Theory discusses Godel's Incompleteness Theorem as a landmark in the Foundations of Mathematics which has meaning for mathematicians, logicians, and philosophers alike.

The Independence of the Continuum Hypothesis discusses the nature of independence proofs and briefly describes the boolean valued logic used to obtain the independence results.
