A Data Acquisition And Processing System For High Frequency Repetitive Waveforms, Daran Lynn Rehmeyer

LSU Historical Dissertations and Theses

The purpose of this thesis is two-fold: to develop a computerized data acquisition system to replace a system using an oscilloscope-mounted Polaroid camera for recording waveforms, and secondly, to develop the processing software to supplement and ultimately replace the manual interpretations of the recorded signals. The impetus for upgrading the original acquisition system is provided by two main factors. The first is the volume and cost of the film required to record an entire waveform using the Polaroid camera and second, the time consuming method of recording and splicing the individual pictures together to form a complete waveform. The current …

Three Essays In The Economics Of The Physician Firm, William David Bradford, Iii

LSU Historical Dissertations and Theses

This dissertation explores three aspects of the physician firm. As such, the current work is concerned with the contribution that quality considerations can make toward our understanding of the medical market. The first of three essays introduces quality into the literature aimed at estimating the supply function of physician firms. This study finds that explicit modeling of quality, both theoretically and empirically, produces results superior to past work in this field and indicates that physicians behave as if they are competitive economic agents. The second essay considers the effect of Medicaid on the behavior of physicians, especially their allocation of …

Distribution And Migration Patterns Of Subsurface Fluids In The Wilcox Group In Central Louisiana, Masaaki Funayama

LSU Historical Dissertations and Theses

Variations of pore fluid properties as well as lithologies in central Louisiana were investigated using more than 300 conventional well logs in order to understand processes and patterns of fluid flow in the Wilcox Group in the region. A statistical evaluation of log parameters was done to provide information required for interpreting older logs in the region.

Most of the study area is located between the northern and southern Louisiana salt dome basins, and there is a general lack of significant structural deformation. The two discrete sand dominated zones in the study area are the Wilcox and the post-Vicksburg groups. …

Geology And Volcanology Of The Recent Evolution Of Galeras Volcano, Colombia, Marta Lucía Calvache

LSU Historical Dissertations and Theses

Galeras volcano is located in southwestern Colombia, rising 1600 m above Pasto the capital city (population of 300,000) of the department of Nariño. The most recent activity at Galeras volcano(< 4500 years) included six major eruptions before the reactivation of 1988-present. The activity at the volcano has been characterizated by eruptions of vulcanian type. Gravitational column collapse is the most common origin of the fines-depleted co-ignimbrite breccias and pyroclastic flows. Commonly, a large part of the material ejected with each explosion is not juvenile but includes country rock as accessory lithics. In the initial explosions at Galeras, the country rock appear to be more involved that any other material. Later in the eruption, the products become more juvenile-rich deposits. The total volume of deposits related to Galeras volcano has been calculated to be 0.71 km³

Galeras volcano has had a fairly constant chemical composition, characterized by high silica, medium potassium andesites. Products at Galeras are mainly composed of zoned plagioclase, hypersthene, augite, titanomagnetite, ilmenite and traces of apatite. Amphibole and olivine may be also present. A shallow, small magma ( « 0.5 km³) chamber is consistent with the data for Galeras Volcano. The magmatic conditions in this reservoir prior to eruptions have …

Relationships Between Wetland Fragmentation And Recent Hydrologic Changes In A Deltaic Coast, R. Eugene Turner, Yeleswarapu S. Rao

Faculty Publications

Patterns in coastal wetland loss in the northern Gulf of Mexico were examined using aerial imagery from 1955–56 and 1978. Five qualitative types of wetland changes are evident: (1) spoil bank-parallel pond formation, (2) pond formation with apparent random distribution for the smallest ponds, but very clumped distribution for larger ponds, (3) semi- or complete impoundment resulting in open water formation, (4) cutting off of stream channels upstream of where a spoil bank crosses a natural channel, and (5) erosion at the land-water interface. Only pondsinterval, and it is clear that wetland breakup, not erosion at the pond-lake edge, is …

Suppression Of Lymphocyte Proliferation By A > 30,000 Molecular Weight Factor In Horse Conceptus-Conditioned Medium, T. L. Roth, K. L. White, D. L. Thompson, B. E. Barry, J. S. Capehart, D. R. Colborn, M. H. Rabb

Faculty Publications

In this experiment we have identified and partially characterized the immunosuppressive activity of preimplantation horse conceptus-conditioned medium (HCCM). Horse conceptuses were nonsurgically flushed from mares at Days 9-10 (n = 6), 15-16 (n = 3), and 25-26 (n = 3). After incubating the conceptuses for 24 h in RPMI-1640 supplemented with 15% fetal calf serum (FCS) and 1% penicillin/streptomycin, HCCM was obtained from cultures and tested for immunosuppressive activity in lymphocyte proliferation assays. Peripheral blood lymphocytes obtained from randomly selected mares were stimulated with mitogens (pokeweed mitogen [PWM], concanavalin A [Con A], and phytohemagglutinin [PHA]) in cultures supplemented with 0%, …

On An Excluded-Minor Class Of Matroids, James G. Oxley

Faculty Publications

A result of Walton and the author establishes that every 3-connected matroid of rank and corank at least three has one of five 6-element rank-3 self-dual matroids as a minor. One of these matroids is the rank-3 whirl W3. Another is the rank-3 matroid P6 that consists of a single 3-point line together with three points off the line. This paper determines the structure of the class of matroids that is obtained by excluding as minors both W3 and P6. As a consequence of this result, we deduce a characterization of the class of GF(4)-representable matroids with no W3-minor. © …

Evolution Of The Site Of Afton Villa, Kathleen Mills Perilloux

LSU Historical Dissertations and Theses

The gardens of Afton Villa Plantation are a rare surviving example from the 1840-1860 period in Louisiana. The gardens are open to the public and are being maintained and enhanced by the present owners. The site was placed on the National Register of Historic Places in 1983. The history of the entire site of Afton Villa in West Feliciana Parish, Louisiana is discussed, tracing the historical, cultural and design influences that affected the site's development, beginning with the original settlers in the late 1700's. The house and gardens known as Afton Villa, built in 1849 by wealthy planter David Barrow …

Geology, Volcanology, And Petrology Of Cerro Bravo, A Young, Dactic, Stratovolcano In West-Central Colombia, David Tondl Lescinsky

LSU Historical Dissertations and Theses

The northernmost active Andean volcano, Cerro Bravo is a small, young, and very explosive stratovolcano. Cerro Bravo has produced voluminous tephra deposits, that are found> 30 km away, as well as, pumice flow deposits, block and ash flow deposits, and high-aspect lava flows, which are found proximally to the volcano. There have been eight episodes of activity during the past 6250±110 years (Herd, 1982), with the most recent <200 years ago and the present being a period of quiescence with no visible activity or thermal manifestations. Stratigraphic relationships suggest the occurrence of an initial explosive phase and a concluding effusive phase of activity during individual episodes. The products of volcanic activity at Cerro Bravo are a chemically and mineralogically monotonous suite of medium-K dacite and high-silica andesite (59.2- 67.5% SiO₂ pumices and lavas. The dominant phenocrysts present are plagioclase and hornblende (oxyhomblende in lavas) with lesser quantities of orthopyroxene, titanomagnetite, and rare augite and biotite also present. Petrology and eruption dynamics …
