A Seismic Analysis Of Reefs In The Traverse Limestone Of Allegan County, Michigan, William Charles Henderson

Masters Theses

A seismic reflection study was performed across the Diamond Springs oil field in Allegan County, Michigan. The horizon of interest was the Middle Devonian Traverse Limestone located 1,700 feet in the subsurface. Within the Traverse Limestone are scattered patch reefs which characterize a targeted reservoir. The use of high-resolution, shallow seismic reflection techniques are useful for defining detailed subsurface porosity zones within the patch reef reservoirs.

Common source-offset profiling utilizing high-frequency sources and proper determination of field parameters are important in obtaining the desired optimum reflection. Also, the use of synthetic seismograms for modeling waveforms is essential for identifying the …

Micellar Catalyzed Hydrolysis Of Hydroxamic Acids By Perfluorooctanoic Acid, Mohammad Hashem Akhavan Tafti

Masters Theses

The work reported herein demonstrated that a perfluorocarboxylic acid does indeed behave as a reactive counterion surfactant exhibiting micellar catalysis, this conclusion was further verified by subsequent experimentation.

Rates of acidic hydrolysis of octano-, phenylaceto-, and 4-bromo phenylacetohydroxamic acid have been determined in aqueous perfluorooctanoic acid--a reactive counterion surfactant system. Typical micellar catalysis was observed for the hydrolysis of octanohydroxamic acid but not for the arylacetohydroxamic acids.

Further investigation into finding a more water soluble surfactant which has reactive counter ions is suggested in order to test the theoretical equation (based on the pseudo phase model) appropriate for this surfactant …

Recoil Corrected Continuum Shell Model Form Factor Calculations For 4He(E,E’)4He(0+), Jiang Yu

Masters Theses

Charge form factor calculations for the electroexcitation of the ⁴He, 0⁺ state have been performed within the context of the recoil corrected continuum shell model. A pure Os⁴ ground state structure is assumed and full internal coordinate recoil corrections are made. The result is compared with available data. It is demonstrated that the 0+ state may be described in a 1p -1h shell model context. Inclusion of nsOs^-1 ground state correlations is suggested for further research.

The Relationship Of Pore Volume And Pore Size Distribution To The Development Of Gloss And Scattering Coefficient, John A. Cook

Masters Theses

This study describes in a quantitative manner the relationships between coating structure and optical properties. Gloss, scattering coefficient and void volume were measured after applying different blends of polystyrene spheres to mylar film. Each coating was modeled using large spherical particles of the same size ratios to measure pore size distribution. The coating structure followed well with theoretical packing characteristics of spheres. Optical properties were related to changes in coating structure. Scattering coefficient and gloss correlated better with pore size distribution than particle size. Gloss increased when total void volume was reduced, while the scattering coefficient decreased.

Electrical Resistivity As An Approach To Evaluating Brine Contamination Of Groundwater In The Walker Oil Field, Ottawa County, Michigan, Janet A. Koehler

Masters Theses

Surface electrical resistivity successfully defined brine contamination within a glacial drift aquifer in western Michigan. The study site is in a residential area of eastern Ottawa County, in the Walker Oil Field. A Schlumberger array with a maximum current electrode separation (AB/2) of 316 meters (1037 feet) was used. It was possible to detect geoelectric layers to about 30 meters (100 feet) below ground level, with the maximum current penetration of about 1/10 (AB/2). On occasion, thick surficial clay precluded detecting deeper geoelectric layers. Through use of the INVERS computer program, fifty vertical electrical soundings were interpreted and correlated with …

An Investigation Of A Soil Gas Sampling Technique And Its Applicability For Detecting Gaseous Pce And Tca Over An Unconfined Granular Aquifer, Timothy J. Mayotte

Masters Theses

A soil gas sampling and analytical technique was investigated to evaluate its ability and versatility for detecting chlorinated hydrocarbons in unconfined aquifers. The technique was used successfully to delineate plumes of perchloroethene (PCE), and 1,1,1-trichloroethane (TCA) contamination present in the vadose zone, and at the water table of an unconfined sand and gravel aquifer. Soil gas samples were obtained by concentrating PCE and TCA vapors diffusing from these sources onto a sorbent material. The samples were analyzed by gas chromatography. The data from the analysis of these samples were used to provide an initial estimate of the source areas, and …

Single-Electron Capture And Loss Cross Sections Vs. Target Z For 1 Mev/U Oxygen Ions Incident On Gases, Scott Avery Boman

Masters Theses

Cross sections for 1 MeV/u oxygen projectile ions which have gained or lost an electron after passing through a gas target were measured as a function of target Z for several incident projectile charge states. The targets used were D_2, He, Ne, Ar and Kr, and the projectiles had charges of 5+, 6+, 7+ and 8+.

The electron capture measurements are generally in reasonable agreement with existing theoretical and empirical scaling rules. The electron loss cross sections differ appreciably from predictions of the PWBA, particularly for the heaviest targets studied. Empirical scaling relationships are derived for the present capture …

Fission-Track Geochronology And Geothermometry Of Late Cretaceous-Early Tertiary Epizonal Plutons, In And Adjacent To The Lombard Thrust Fault, Southwestern Montana, Jean Talanda

Masters Theses

Thrusting occurred in the central portion of the central Montana salient where the timing of movements is somewhat obscured by the multiple deformations from Archean time to the present. The relationship of this thrusting to the associated plutons has not been established in every case. Fission-track geochronology was employed in dating several plutons associated with the Lombard thrust fault, consequently, defining a time range in which movement along the thrust occured.

Seven plutons with known structural relationships to the Lombard thrust have ages which suggest that movement along the fault occurred 73.2 +/- 6.7 Ma. Fission-track length distributions suggest that …

Synthesis And Study Of Novel Quinoxaline Di-N-Oxide And 3-Acyl-2-Methylquinoxaline Di-N-Oxides, Cyprian Okwara Ogbu

Masters Theses

This research project consists of two parts. The first involved the synthesis of a novel quininoxaline di-N-oxide via benzofuroxan. The second part was the use of this compound as a synthetic precursor.

It was assumed that 3,4-dimethylaniline would be successfully converted to 5,6-dimethybenzofurazan 1-oxide (5,6-dimethybenzofuroxan) through a sequence of reaction steps. Fortunately, this assumption was correct as the desired compound was produced. This compound was utilized in synthesizing the novel 3-acetyl-2,6,7-trimethylquinoxaline 1,4-dioxide. From the structure of this adduct, it is believed that it will take part in condensation reactions associated with methyl ketones without disrupting the quinoxaline di-N-oxide framework, and …

The Significance Of Organic Complexing In The Mobility Of Iron In The Kl Landfill Leachate Plume, Kalamazoo, Michigan, James D. Rudder

Masters Theses

High iron concentrations in the leachate plume of the KL Landfill in Kalamazoo County, Michigan, persist in the presence of detectable hydrogen-sulfide. Under these conditions iron-sulfide minerals are highly oversaturated and should be precipitating. Calculations performed by the chemical equilibrium model WATEQF indicate over-saturation of selected iron-oxides, siderite, and iron-sulfides. Semilog plots of iron concentration versus time of exposure to air demonstrate retarded precipitation of ferric hydroxide, and analytical techniques of ion chromatography, Fourier transform IR spectrophotometry (FTIR), and UV-Visible spectrophotometry have yielded results which indicate that organic complexing of ferrous iron plays a significant role in the mobility of …

Behavior Of Reinforced Loess Specimens Under Triaxial Load, Mohammad Taghi Izadi

Masters Theses

"Effects of reinforcement on shear strength of a loessial (silty) soil arc studied. Unconsolidated undrained triaxial tests are performed on unreinforced and fabric reinforced soil specimens. Analyses of the test results showed that in general the shear strength of remolded loess specimens were improved substantially and increase in the shear strength was directly related to reinforcement spacing.

The mechanism of soil-reinforcement interaction and several existing analytical models are described. A modified analytical model based on enhanced confining theory is developed. This model can be used in assessing the effects of the reinforcement on shear strength of triaxial specimens. Comparison of …

Deduction Of A Functional Dependency From A Set Of Functional Dependencies, James M. Richardson

Masters Theses

"This paper describes an algorithm called the Deduction Tracing Algorithm (DTA) which utilizes basic properties of functional dependencies from database systems and a modification of a tree search algorithm from artificial intelligence. The algorithm takes a set of functional dependencies, F, along with a specific functional dependency L→R as input and produces a list of functional dependencies from F that can be used to deduce L→R. The resulting algorithm is easily automated to provide relational database users with a tool for organizing their queries"--Abstract, page iii.

Fractals With Arbitrary Segment Lengths, Daniel Michael Doerer

Masters Theses

"Work in the area of fractal geometry has generally focused on a specific facet of the discipline at the expense of other interesting features. This approach often generates more questions than answers for the general audience due to the lack of unification across all views. It appears that a common thread to relate all aspects of fractal characteristics is missing. This paper addresses this question and presents some new and fascinating results. For example, in-depth mathematical analysis often defers to the intriguing and attractive graphical displays produced by mapping the complex plane to the pixel field on a CRT. Both …

A Parallel Implementation Of Stickel's Ac Unification Algorithm In A Message-Passing Environment, David John Kleikamp

Masters Theses

"Unification algorithms are an essential component of automated reasoning and term rewriting systems. Unification finds a set of substitutions or unifiers that, when applied to variables in two or more terms, make those terms identical or equivalent. Most systems use Robinson's unification algorithm or some variant of it. However, terms containing functions exhibiting properties such as associativity and commutativity may be made equivalent without appearing identical. Systems employing Robinson's unification algorithm must use some mechanism separate from the unification algorithm to reason with such functions. Often this is done by incorporating the properties into a rule base and generating equivalent …

Coal Desulfurization Using Pyrite Conversion Through Dielectric Heating, Daniel C. Cleaveland

Masters Theses

The Illinois State Geological Survey is currently developing a three step coal desulfurization process which depends upon the in-situ generation of catalytic troilite (FeS) by reduction of the pyrite (FeS₂) present in the mineral fraction of coal. After catalyst generation, ethanol is added to the system and is dehydrogenated to acetaldehyde and hydrogen which removes organic sulfur as hydrogen sulfide. The research reported in this thesis shows that the process can be improved by the use of dielectric heating in place of thermal heating for catalyst generation and perhaps organic sulfur removal. It is found that pyrite reduction …
