Multiscale Analysis For Characterization Of Remotely Sensed Images., Wei Zhao Jan 2001

Multiscale Analysis For Characterization Of Remotely Sensed Images., Wei Zhao

LSU Historical Dissertations and Theses

In this study we addressed fundamental characteristics of image analysis in remote sensing, enumerated unavoidable problems in spectral analysis, and highlighted the spatial structure and features that increase information amount and measurement accuracy. We addressed the relationship between scale and spatial structure and the difficulties in characterizing them in complex remotely sensed images. We suggested that it is necessary to employ multiscale analysis techniques for analyzing and extracting information from remotely sensed images. We developed a multiscale characterization software system based on an existing software called ICAMS (Image Characterization And Modeling System), and applied the system to various test data …

Soil Management In Two Highland Guatemalan Municipios: Local Perspectives On The Management And Degradation Of Soil Resources., Steven James Rainey Jan 2001

Soil Management In Two Highland Guatemalan Municipios: Local Perspectives On The Management And Degradation Of Soil Resources., Steven James Rainey

LSU Historical Dissertations and Theses

This dissertation studies how small farmers of two ethnic groups manage the soil resource in a portion of Highland Guatemala that is considered marginal for crop production due to steep slopes. In the past, various groups concerned about environmental degradation tended to blame peasant farmers such as these for degrading the land resource through "primitive and backward" agricultural practices and a general lack of knowledge of the consequences of their actions. Yet attempts to convince small farmers to adopt new techniques have often failed due in part to an inadequate knowledge of local conditions and to a failure to recognize …

Some Technical Vocabulary Of Rhetorical Invention In The Treatise Of Anonymous Seguerianus, Hermogenes' "On Statis", And Book Three Of The [Pseudo-]Hermogenic Work "On Invention", Mark Allen Williams

LSU Historical Dissertations and Theses

From the debates of the Christian councils to the homilies of the local priests, from the opaque scripting of the Byzantine epistle to the clarities of stasis theory, from the entertaining fictions of declamation to the promulgation of Byzantine cannon law, the citizens of Byzantium were never far from the rhetorical, and they themselves knew it. But the development of rhetorical theory in the Greek West has gained little attention, and what has been given to it has generally concentrated on questions of style. This dissertation examines some of the most basic qualities of that theory of rhetorical invention which …

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds Jan 2001

T -Cell Cytokines And Equine Nematode Infections., Jenifer Dee Edmonds

LSU Historical Dissertations and Theses

To address the role of parasites on subsequent antigenic challenge, humoral, lymphoproliferative and cytokine responses to a single intramuscular injection of keyhole limpet haemocyanin (KLH) were compared between groups of ponies with high, medium or low gastrointestinal parasite burdens. Heavy and moderately parasitised animals showed a trend towards reduced KLH-specific lymphoproliferation and reduced antigen specific total immunoglobulin, IgG(T) and IgA compared to lightly parasitised ponies. The peripheral blood mononuclear cells (PBMC) from medium and heavily parasitised ponies also had significantly lower levels of IL-4. These data indicate that heavily parasitised animals have uniformly decreased cellular and humoral immune responses to …

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel Jan 2001

An Economic Analysis Of The Allocation Of Research Funding At The National Institutes Of Health., Janet B. Daniel

LSU Historical Dissertations and Theses

Our model examines the allocation of medical research funds at the National Institutes of Health using public interest theory, incremental budgeting theory, and special interest group theory. We use the allocation of research funds among various diseases and measures of the burden of disease on the population to test the hypothesis that the N.I.H. is allocating funds on a pure public interest basis, to test for incremental budgeting effects, and to test for the influence of lobbying and other political variables representing special interest groups. We use pooled cross-sectional, time-series data in a one-way fixed effects model, and also use …

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry Jan 2001

Body Condition, Leptin, And Reproductive Characteristics In Horses., Laura Roland Gentry

LSU Historical Dissertations and Theses

A series of experiments was conducted to gain a better understanding of the effects of nutrition and hormonal manipulation on the reproductive processes of the horse. In Experiment 1, body condition score (BCS) and ultrasonic backfat measurements were highly correlated in mares, especially over the tailhead area. In Experiment 2, high BCS (HBCS) mares continued to ovulate during the winter anestrous period, whereas low BCS (LBCS) mares went deeply anestrous. Daily hormone concentrations were not affected by BCS, however, responses to hormonal challenges indicated cyclicity in HBCS mares and reproductive quiescence in LBCS mares. In Experiment 3, treatment of average …

Statistical And Simulation Modeling Of Brown Shrimp Population Dynamics In The Northern Gulf Of Mexico., Heather Lynn Haas Jan 2001

Statistical And Simulation Modeling Of Brown Shrimp Population Dynamics In The Northern Gulf Of Mexico., Heather Lynn Haas

LSU Historical Dissertations and Theses

This dissertation used statistical and simulation modeling to examine population dynamics of brown shrimp, Penaeus (Farfantepenaeus ) aztecus. Brown shrimp are ideal to use in examining recruitment because shrimp represent a common life history strategy, because they are commercially important, and because there are extensive data available. In the first section of this dissertation, I used long-term monitoring data to examine correlative relationships between annual, stage-specific abundance estimates and environmental factors. Criticisms of traditional correlative studies were addressed by using a spatially and temporally-extensive dataset, by comparing stepwise multiple regression to Bayesian model averaging, and by investigating nonlinear relationships with …

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire Jan 2001

Evaluating The Taxonomic Status Of The Great White Heron (Ardea Herodias Occidentalis) Using Morphological, Behavioral And Genetic Evidence., Heather Louise Mcguire

LSU Historical Dissertations and Theses

The Great White Heron was originally described as a distinct species (Ardea occidentalis), but is currently considered to be the white morph of a polymorphic Great Blue Heron subspecies (A. herodias occidentalis). Great White and Great Blue heron breeding ranges overlap in the Florida Keys (USA), providing an opportunity to evaluate the degree to which these two taxa are reproductively isolated. The current classification leads to predictions of no significant size difference (H01), random mate choice (H02), and no genetic divergence (H03) between sympatric white and blue herons. Sympatric Great White and Great Blue herons did not differ significantly in …

An Introduction To Jacques Leguerney's Settings Of The Poetry Of Pierre De Ronsard., Carol Fuqua Lines Jan 2001

An Introduction To Jacques Leguerney's Settings Of The Poetry Of Pierre De Ronsard., Carol Fuqua Lines

LSU Historical Dissertations and Theses

Jacques Leguerney, French composer who lived from 1906--1997, is at last gaining a much-deserved place in the history of the French melodie. Primarily a composer of melodie, Leguerney was strongly drawn to the poetry of the French Renaissance, with more than one-third of his songs utilizing the poetry of members of the French Renaissance School known as La Pleiade, founded by poet Pierre de Ronsard. Ronsard's poetry is found in the majority of Leguerney's Pleiade settings, of which ten are presented in this study. The ten selections are: Je vous envoie, Genievres Herisses, Je me lamente, Bel aubepin, Si mille …

Effects Of Nitric Oxide Synthase Inhibitors On Equine And Bovine Follicular Dynamics And Steroidogenesis., Carlos Roberto Fontes Pinto

LSU Historical Dissertations and Theses

Current scientific literature has shown that: (1) NO is a pro-ovulatory agent and inhibition of its production inhibits ovulation, and (2) NO has strong antisteroidogenic activity, especially on estradiol (E2) production by granulosa cells. The experiments described in this dissertation were designed to answer the following questions involving effects of NO on ovarian physiology: (1) is the inhibitory effect of nitric oxide synthase (NOS) inhibitors on ovulation irreversible (follicular atresia) or temporary (delayed ovulation)? and (2) what is the relationship between NO and hCG-induced preovulatory luteinization? Accordingly, cycling mares were subjected to treatment with NOS inhibitors (L-NAME or aminoguanidine) during …

Production, Process Design And Quality Characterization Of Catfish Visceral Oil., Subramaniam Sathivel

LSU Historical Dissertations and Theses

Between 45--55% of viscera, head, skin, intestine and slurries are generally generated as byproducts or waste from catfish filleting process. Our preliminary study showed that the crude fat content of the whole catfish viscera was 30--35% (wet basis) and the total o-3 fatty acids of oils recovered from the whole and/or portioned viscera ranged from 4.3--20.9 mg/g (dry basis). Catfish viscera may serve as an excellent source of health-promoting oil. Yield of purified (deodorized) catfish visceral oil was 65.7% and contained considerable amounts of DHA (1.21 mg/g of oil) and omega-3 fatty acid (4.6 mg/g of oil). A rapid microwave-assisted …

Numerical Simulations Of Incompressible Flows In Complex Geometries., Konstantinos Vogiatzis Jan 2001

Numerical Simulations Of Incompressible Flows In Complex Geometries., Konstantinos Vogiatzis

LSU Historical Dissertations and Theses

A mainly spectral code along with domain-decomposition, a combination that is not widely in use in complex problems, has been developed for the solution of the 3-D unsteady incompressible Navier-Stokes equations. The code uses fully spectral or a combination of spectral-collocation and finite difference approximations and a 3-step splitting time-marching scheme. The developed Poisson solver utilizes matrix diagonalization and incorporates a direct sub-structuring method based on the influence matrix technique. As a first step, laminar and turbulent confined flows were simulated, initially with DNS, then with LES, using a modified Smagorinksi model. The domain-decomposition technique and parallel implementation were tested …

Patterns Of Reef Fish Larval Supply To Petroleum Platforms In The Northern Gulf Of Mexico., James Marvin Tolan

LSU Historical Dissertations and Theses

Surveys of ichthyoplankton assemblages were conducted from four oil and gas platforms located in the northern Gulf of Mexico from November 1994 through July 1997. Diurnal collections, supplemented with light trap collections from the surface and -20 m depth, were taken quarterly during 1994 and 1995. Quarterly ichthyoplankton sampling at dawn and dusk only during 1996 and 1997 were supplemented with surface "lighted plankton net" collections. Of the 36,676 individuals collected, epipelagic (neretic and oceanic Clupeiformes, neretic Carangidae and Lutjanidae, as well as oceanic Scombridae) and mesopelagic (Myctophidae and Gonostomatidae) families comprised the majority of the ichthyoplankton. Reef-dependent (e.g., Pomacentridae, …

"Sometimes The Road Less Traveled Is Less Traveled For A Reason": The Need For Change In Georgia's Employment-At-Will Doctrine And Refusal To Adopt The Public Policy Exception, Nancy Baumgarten Jan 2001

"Sometimes The Road Less Traveled Is Less Traveled For A Reason": The Need For Change In Georgia's Employment-At-Will Doctrine And Refusal To Adopt The Public Policy Exception, Nancy Baumgarten

Georgia Law Review

This Note calls for the adoption of the public policy exception to the employment-at-will doctrine in the state of Georgia. Georgia employees need a viable claim at the state level since federal relief may not always be an option for a Georgia plaintiff. Furthermore, the adoption of this exception is directly in line with Georgia's policies in other areas of law. Finally, since it is the same employers who have placed Georgia in the bottom twenty-five percent of the nation for the highest rate of job discrimination that can terminate Georgia' employees for reasons which violate public policy, the need …
