An Analysis Of Nitrate Concentrations In The Ground-Water Of Antwerp Township, Van Buren County, Michigan, John Emil Klanke

Masters Theses

Private wells were tested for nitrate during the spring of 1979 throughout sections of Antwerp Township, Van Buren County, southwestern Michigan (sections 1-5, 7-22, 24-26, 28-31, 33-36). Water samples were collected from 159 private wells and analyzed for nitrate. Nitrate concentrations ranged from less than 1 mg/1 NO₃-N to 14.6 mg/1 NO₃-N. Seven wells were found to have nitrate concentrations equaling or exceeding the National Interim Primary Drinking Water Standard of 10 mg/1 NO₃-N. Nitrate concentrations were related to age of septic system, well depth below static water level, land use, and soil type. …

Structural Analysis Of Precambrian Metasedimentary Rocks Of The Swede Gulch Formation, Nahant, South Dakota, Richard G. Cookman

Masters Theses

Precambrian X tectonites deformed between thermal domes in the northern Black Hills 1.7 B.Y.B.P. display variably trending isoclinal folds cross-cut by southeast trending slip-folds developed in discrete shear zones. Eugeosynclinal sedimentary rocks consisting of shale, quartzarenite , sublitharenite, and graywacke were metamorphosed to phyllite, quartzite, and metagraywacke during two syntectonic phases and one post-tectonic phase. The earliest syntectonic metamorphism was associated with development of isoclinal folds and may have produced amphibolite or greenschist facies. It was succeeded by retrograde metamorphism of greenschist facies syntectonic with and post-tectonic to development of southeast trending folds.

Mica, chlorite, iron oxides, and graphite are …

Hydrology Of The Sinking Creek System, Logan And Simpson Counties, Kentucky, James C. Cubbage

Masters Theses & Specialist Projects

Southwest of Bowling Green, Kentucky, is the Western Pennyroyal, is a karstified area which has been neglected in the study of its ground water. About 100 square miles near Adairville were chosen for analysis to help rectify this lack of knowledge. The area is dominated by Sinking Creek, a surface-subsurface drainage system.

The main purpose of the study was to map the underground flow in the Sinking Creek area. The drainage system seemed to be typical for the Western Pennyroyal and exhibited many similarities to flow paths known in the Central Kentucky Karst.

The investigation proved to be of basic …

Hot-Wire Anemometer Behaviour In Low Velocity Air Flow, P. J. Christman, Josef Podzimek

Physics Faculty Research & Creative Works

The behavior characteristics of a commercially available hot-wire anemometer have been examined in the presence of low velocities, lwss than 0.1 m/s for the most part, and in both horizontal and vertical air flows. The orientation of the probe in a horizontal flow has been found to have a definite effect on velocity measurements, and a lower limit to the reliable application of hot-wire anemometry has been evaluated for a particular type of probe. Vertical flow measurements have resulted in the discovery of the magnitude of natural convective velocity, and a possible method for determining the dimensions of the temperature …

The Anodic Stripping Voltammetry Determination Of Trace Elements In Coal Ash, Jesus Montoya

Masters Theses & Specialist Projects

The application of anodic stripping voltammetry (ASV) to the determination of several trace metals in coal ash was studied.

An ashing and ash digestion method was developed which limited the total salt and acid concentration of the analyte solutions, a necessary step for routine analysis. The simultaneous determination of cadmium, copper, lead, and zinc in eight Pennsylvania State University Coal Bank Samples and in the National Bureau of Standards SRM 1632a coal sample were made. Chromium was separated from the prepared coal ash solutions and determined independently in the form of chromate(VI).

All values determined by ASV methods were in …

Metrizability And The Frechet-Urysohn Property In Topological Groups, Peter J. Nyikos

Faculty Publications

A question of Arhangel'skii, whether weakly first countable topological groups are metrizable, is answered in two ways: if the Hausdorff axiom is assumed, the answer is yes, but in general a weakly first countable topological group need not be pseudometrizable. The former result is obtained as a corollary of a more general sufficient condition for a sequential group to be Fr&chet-Urysohn. A general necessary and sufficient condition for a sequential group to be Frechet-Urysohn is given, and a number of questions are raised. Examples are given to show in what respect the theorems of the paper are the "best possible".

Petrology Of Fluvial And Shoreline Sands In A Modern Arc-Trench Gap, Guatemala, James Robert Bartel

Masters Theses

Petrographic studies of modern sands, derived from areas with known source rocks, climate, relief, environments of deposition, and tectonic setting, are essential for compiling compositional models for ancient sandstones. The Pacific coastal plain of Guatemala is terminated 25-60 km inland by the steep slopes of a row of active Quaternary volcanic and granitic rocks.

Sands being deposited on the coastal plain by the Rio Nahulate, which drains the older volcanic and granitic terrane, show significant compositional differences with those supplied by the Rio Samala, which drains an area dominated by active volcanism: Q₉F₃₅L₅₆ vs. Q …

The Determination Of A Relative Chronology For A Surface Archeological Site Using The Obsidian Hydration Dating Method, Scott Preston Thomas

Dissertations and Theses

This methodological study is an attempt to develop relative chronologies for surface archaeological sites from the obsidian hydration analysis of waste flake samples. Two sites in southeastern Oregon were selected and their surface components sampled. The results of the obsidian hydration analysis indicate, that with the use of random sampling methods and general geochemical control, a fairly accurate representation of the history of an archaeological surface site can be obtained.

Mid‐Level Intrusions At The Continental Shelf Edge, Christopher S. Welch

VIMS Articles

Observations across the continental shelf offshore from New Jersey in late summer 1976 show an intrusion of saline water at the mid level of the water column across the shelf edge front, which appears in density only as an offshore thickening of the pycnocline. This internal density field produces horizontal pressure gradient forces within the pycnocline in the onshore direction. These forces, in the linearized equation of motion with a constant eddy viscosity, drive a circulation which resembles a double Ekman spiral for internal pressure vertical distributions which are thin with respect to the Ekman depth. For thick pressure distributions, …

Chemistry Of Chromium Oxyfluorides And Group Vib Perfluoroglutarates, Bruce Michael Johnson

Dissertations and Theses

Pure chromium oxide trifluoride was prepared for the first time by reaction of CrO₃ and ClF with subsequent multiple fluorine treatments at 120°C. On the basis of its infrared spectrum, the purple CrOF₃ was assigned as a fluorine-bridged polymer with terminal oxygen groups. Chromium oxide trifluoride was found to be stable to 300°C, where it decomposes with the loss of oxygen to CrF₃.

Bilinear Equation For The Cylinder With Overlap And The Pomeron Residue, Paul Finkler, C. Edward Jones

Paul Finkler Papers

A bilinear integral equation for the cylinder is derived within the meson sector of the theory of dual topological unitarization. The equation is more general than conventional linear cylinder equations since it includes regions of phase space in which produced particles overlap in rapidity. The equation also permits a simple treatment of phase space which corresponds to that of the planar bootstrap problem. Two classes of solutions are found, only one of which results in the Pomero'n-f identity. This treatment also indicates that the residue of the Pomeron may be twice as large as that suggested by earlier calculations …

Some Results On Optimum Premium Payment Plans, Jeyaraj Vadiveloo, Kishan Mehrotra, Kenneth Kaminsky

Electrical Engineering and Computer Science - Technical Reports

Any insurance plan consists of a sequence of payments every year (or some other fixed time interval) in return for certain death benefits. The benefits may take the form of a wide variety of insurances or annuities. For simplicity, we will assume that premiums and benefits are paid annually. In this paper, we investigate the appropriateness of this type of plan. Naturally, appropriateness of any plan cannot be measured without an optimality criteria. Three such criteria, which are statistical in nature, are introduced in this paper. For the principal "safety" criterion which we use, the optimal premium are those which …

Additive Comparisons Of Stop Rule And Supremum Expectations Of Uniformly Bounded Independent Random Variables, Theodore P. Hill, Robert P. Kertz

Research Scholars in Residence

Let X_I, X₂, . . . be independent random variables taking values in [a, b], and let T denote the stop rules for X₁, X₂, Then E(sup_n>1 X_n) - sup{ EX_t t ≡ T} < (1/4)(b - a), and this bound is best possible. Probabilistically, this says that if a prophet (player with complete foresight) makes a side payment of (b - a)/8 to a gambler (player using nonanticipating stop rules), the game becomes at least fair for the gambler.

Use Of Magnesium (Mg) For Crop Production In Kentucky, John H. Grove

Soil Science News and Views

Magnesium (Mg) is an important element in the nutrition of plants and animals, although it has long been considered a "secondary" nutrient for plants. Nitrogen (N), phosphorus (P), and potassium (K) are "primary'' nutrients and are usually given the greatest consideration in crop fertility programs. However, as yield levels have risen, more attention has been directed towards Mg and other nutrient elements. Concern about hypomagnesemia (grass tetany) in ruminants (cattle, sheep) has led to particular concern about soil and plant Mg levels.

Characterization Of La Verkin Springs Water And Methods For Its Reuse In Energy Development, United States Department Of The Interior, Bureau Of Reclamation

Water

Analytical water data obtained from a 9-month test program at the LVS (LaVerkin Springs) site, which is located in Washington County, Southwestern Utah, were evaluated. Fresh water and the water after processing through various pretreatment steps and after ED (electrodialysis) desalting and by desalting processes was demonstrated by the LVS site test program. The relative merit of different methods of treatment, disposal, and reuse of LVS water were studied. The objectives of the study were to evaluate methods for preventing high salinity LVS water from entering the Virgin River and for utilizing the processed water in energy development. The disposal …

Statistics Of Multicharge Centers In Semiconductors - Applications, David C. Look

Physics Faculty Publications

A general formula is derived for the electron occupation numbers appropriate for multicharge centers in semiconductors, including excited states. The results are used to rederive and generalize several formulas of interest in the literature, in order to show exactly how the degeneracies of individual states enter in. Particular attention is paid to certain subjects which are sometimes confusing, such as how the statistics of band states differ from those those of localized states. Another subject of much recent interest, negative-U centers, is dealt with in some detail. We show how the dependence of the average occupation number on Fermi …

Magnetic And Electrical Properties Of Iron-Nickel-Chromium-Metalloid Glasses, H. Sadate-Akhavi, George C. Hadjipanayis, David J. Sellmyer

David Sellmyer Publications

The magnetic and electrical properties of amorphous (Fe_1-xNi_x)_78-yCr_ySi₁₀B₁₂ alloys have been measured between 4.2 and 300 K. Alloys with x≤0.9 and y=5 order ferromagnetically. High-field magnetization measurements show saturation in moderate fields suggesting a relatively high value of magnetic anisotropy which was estimated to be K≃10⁶ erg/cm³. The magnetization at low temperatures follows a T^3/2 law leading to a spin-wave stiffness coefficient D≃90 meV Ų. The x=1, y=5 alloy behaves like a "cluster glass" with a cluster ordering temperature around 20 …

Massive Neutrinos And The Stellar Stopping Power Via The Neutrino Magnetic Moment, P.T. Leung, M. L. Rustgi, J. E. Turner, Werner Brandt

Physics Faculty Publications and Presentations

An exact expression is derived within the high-Q approximation for the spectrum of energy losses of neutrinos interacting via their magnetic moment with electrons. A formula for the stopping power of matter for neutrinos is derived and applied to the study of the solar neutrino anomaly. The total inelastic cross section is given. An upper limit is deduced for the neutrino magnetic moment from the antineutrino spectrum as recently parameterized by Lee (1979). It confirms the bound reported by Cowan and Reines. The distance for stellar neutrinos to thermalize by the interactions studied here, through encounters with stars is found …

A Benefit Cost Analysis Of A Soil Erosion Control Program For The Northern Watershed Of Lake Chicot, Arkansas, C. Tim Osborn, Alan D. Mcqueen, Robert N. Shulstad

Technical Reports

Lake Chicot, a 5,025-acre oxbow lake created by the ancient meandering of the Mississippi River, is located near the town of Lake Village in Chicot County of southeastern Arkansas (Fig. 1). Today the lake is separated into a northern basin of 1,154 acres and a southern basin of 3,871 acres by a levee maintained by the Arkansas Game and Fish Commission (Fig. 2). The entire lake once offered excellent fishing and recreational benefits. But with channelization in the drainage basin and final closure of the Cypress Creek gap along the Mississippi River levee in 1920, drainage and flood waters from …
