A New Species Of Petasiger (Digenea: Echinostomiformes: Echinostomatidae) In The Brown Pelican, Pelecanus Occidentalis, (Aves: Pelecaniformes: Pelecanidae), From The Área De Conservación Guanacaste, Costa Rica, David Zamparo, Daniel R. Brooks, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A new species of Petasiger inhabits Pelecanus occidentalis, from the Área de Conservación Guanacaste, Costa Rica. The new species most closely resembles Petasiger novemdecim Lutz 1929 and Petasiger caribbensis Nassi, 1980 by having 19 circumoral spines and vitelline follicles confluent between the ventral sucker and gonads. The new species differs from both of these species by having a cirrus sac that is anteroposteriorly elongate and that reaches posteriorly to the midventral sucker, an ovary and Mehlis' gland that overlap the anterior testis dorsally, a uterus that lies dorsal to the ventral sucker, and a dextromedial genital pore. In P. …

Controllability, Observability And Realizability, Inna N. Smith

College of Graduate Studies: Theses & Dissertations

In this research project, we analyze three important concepts of the control theory, including controllability, observability and realizability. In particular, we analyze the theory of and solutions to linear time systems, continuous and discrete time systems, time-varying systems, and first-order matrix Sylvester systems. Examples and sample computed calculations are provided for both uncontrolled and controlled systems. We also develop a new method for computing the approximate values of matrix exponentials, and use this to estimate solutions to initial value problems.

Acid Mine Drainage: Sludge Dewatering, Metal Recovery And Synthesis Of Magnetite Nanoparticles, Xinchao Wei

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid mine drainage (AMD) is one of the significant environmental challenges for the coal and hard-rock mining industry. Traditional AMD treatment generates large volumes of sludge with low solids which are difficult to dewater. In this study, a systematic investigation was carried out on the characteristics and dewaterability of AMD sludge produced from an ammonia neutralization operation, and the dewatering performance of different treatment options. In order to mitigate the AMD sludge problem, a selective precipitation process was developed to recover Fe and Al while AMD was treated simultaneously. In conjunction, a low-cost synthesis approach was examined to prepare magnetite …

At Work In The Fields : An Essay Into The Work Lives Of Nineteenth Century English Agricultural Wage Labouring And African American Slave And Freed Women., Anne Reeves 1948-

Electronic Theses and Dissertations

This thesis is a historical study comparing the work-lives African-American and English nineteenth-century, field-working women. It focuses on the ideology and structure of the gender division of labour as it formed and informed the lives of these women. It explores the complex relationship among gender and racial ideologies, social and economic structures and the extent to which the women determined their own lives. It argues that the particular historical, ideological and economic forces at work in England and the South differentially constrained their lives. The work is divided into four chapters. The Introduction explains the study's purpose and explores the …

Sex-Based Differences In Regulatory T Cells., Lum Doreen Nebane-Ambe 1975-

Electronic Theses and Dissertations

Females have a higher incidence of autoimmune diseases than males for reasons that are currently unknown. CD4+CD25+ regulatory T cells play an important role in the maintenance of immunological homeostasis and self-tolerance by suppressing autoreactive T cells that could potentially cause autoimmune diseases. Given that autoimmune diseases are more prevalent in women compared to men, we hypothesized that sex steroids could influence the incidence and/or progression of autoimmune disease through an effect on CD4+CD25+ regulatory T cell number and/or function. The overall objective of this project was then to determine whether sex steroids mediate sex-based differences in CD4+CD25+ regulatory T …

Caregivers’ Perceptions Of Accessibility And Quality Of Services In The Community For Children With Mental Health Diagnoses: A Pilot Survey, Karin E. Brems

Masters Theses

This pilot study was intended to explore caregivers' perceptions of the mental health services available in the community for children with mental health diagnoses. A study-specific survey was developed to look at demographic characteristics, service accessibility, and service quality. This survey was distributed to caregivers through Michigan support groups. Returned surveys were analyzed for themes that could assist in the development of further research to improve community services for children with mental health diagnoses.

This pilot study yielded rich qualitative data. Upon review and analysis, five themes emerged: (1) bureaucratic hassles and getting the runaround, (2) closed doors, (3) support …

Actin Nanokinematics Under The Influence Of Dc Electric Fields, Raghu Chilakamarri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Molecular shuttles are nanometer-sized machines capable of transporting single molecules over small distances under user control. Actin-myosin system is a motor protein system, which naturally evolved within the cell for the nanoscale transport. The Acto-Myosin system is fuelled by ATP, converting chemical energy into linear motion. The gliding geometry movement of actin wherein the tails of the motors are adsorbed to the surface and the heads of the motors move the actin filaments across the surface can be exploited to achieve the directional control. The motion of actin in a specific direction and the surface of travel can be modified …

Preliminary Design Approach For Prosthetic Ankle Joints Using Compliant Mechanisms, Jason Matthew Wiersdorf

Theses and Dissertations

The objective of this thesis is to develop design approaches and models for prosthetic ankle joints using kinematic models of the human ankle and compliant mechanisms technology. Compliant mechanisms offer several potential design advantages over traditional rigid-body designs including high reliability and low cost. These design advantages are ideal for use in prosthetics. Some prosthetic ankle/foot systems currently on the market have multiple degrees of freedom yet are expensive. Additionally, even though these systems have multiple degrees of freedom, none of them are designed after the actual movements of the biological ankle. In this thesis a two, single degree-of-freedom hinge …

Regulation By Adaptive Management--Is It Possible?, J.B. Ruhl

Vanderbilt Law School Faculty Publications

Today's voluminous literature on adaptive management traces its roots to Professor C.S. Holling's seminal work, Adaptive Environmental Assessment and Management. Although almost thirty years have passed since he and his colleagues first described the adaptive management methodology, no work on the topic has improved on their core theory. Its essence is an iterative, incremental decisionmaking process built around a continuous process of monitoring the effects of decisions and adjusting decisions accordingly. It is in other words, far more suited to the needs of future regulatory challenges than is prescriptive regulation. My focus, however, is not on what adaptive management should …

Genetic And Molecular Analysis Of Phytochromes From The Filamentous Fungus Neurospora Crassa, Allan C. Froehlich, Bosl Noh, Richard D. Vierstra, Jennifer Loros, Jay C. Dunlap

Dartmouth Scholarship

Phytochromes (Phys) comprise a superfamily of red-/far-red-light-sensing proteins. Whereas higher-plant Phys that control numerous growth and developmental processes have been well described, the biochemical characteristics and functions of the microbial forms are largely unknown. Here, we describe analyses of the expression, regulation, and activities of two Phys in the filamentous fungus Neurospora crassa. In addition to containing the signature N-terminal domain predicted to covalently associate with a bilin chromophore, PHY-1 and PHY-2 contain C-terminal histidine kinase and response regulator motifs, implying that they function as hybrid two-component sensor kinases activated by light. A bacterially expressed N-terminal fragment of PHY-2 covalently …

The Caenorhabditis Elegans Heterochronic Regulator Lin-14 Is A Novel Transcription Factor That Controls The Developmental Timing Of Transcription From The Insulin/Insulin-Like Growth Factor Gene Ins-33 By Direct Dna Binding, Marta Hristova, Darcy Birse, Yang Hong, Victor Ambros

Dartmouth Scholarship

A temporal gradient of the novel nuclear protein LIN-14 specifies the timing and sequence of stage-specific developmental events in Caenorhabditis elegans. The profound effects of lin-14 mutations on worm development suggest that LIN-14 directly or indirectly regulates stage-specific gene expression. We show that LIN-14 can associate with chromatin in vivo and has in vitro DNA binding activity. A bacterially expressed C-terminal domain of LIN-14 was used to select DNA sequences that contain a putative consensus binding site from a pool of randomized double-stranded oligonucleotides. To identify candidates for genes directly regulated by lin-14, we employed DNA microarray hybridization to compare …

Archeological Trends And Book Of Mormon Origins, John E. Clark

BYU Studies

Had circumstances permitted a marked grave for the slain prophet, a fitting headstone could have read, “By Joseph Smith, Junior, Author and Proprietor.” Such an epitaph, taken from the title page of the Book of Mormon, captures the enduring bond between the man and the book, and also the controversy which coalesced around both with the book’s publication and the organization of The Church of Jesus Christ of Latter-day Saints in 1830. In the ensuing and continuing “war of words” (Joseph Smith–History 1:10) and prejudice, redemption may hang on the single preposition “by.” What hand did Joseph have in producing …

A Framework To Learn Bayesian Network From Changing, Multiple-Source Biomedical Data, Li G., Tze-Yun Leong

Research Collection School Of Computing and Information Systems

Structure learning in Bayesian network is a big issue. Many efforts have tried to solve this problem and quite a few algorithms have been proposed. However, when we attempt to apply the existing methods to microarray data, there are three main challenges: 1) there are many variables in the data set, 2) the sample size is small, and 3) microarray data are changing from experiment to experiment and new data are available quickly. To address these three problems, we assume that the major functions of a kind of cells do not change too much in different experiments, and propose a …

Sponge Community Structure And Anti-Predator Defenses On Temperate Reefs Of The South Atlantic Bight, Richard Robert Ruzicka

College of Graduate Studies: Theses & Dissertations

The interaction between predation and anti-predator defenses of prey is important in shaping community structure in all ecosystems. This study examined the relationship between sponge predation and the distribution of sponge anti-predator defenses on temperate reefs in the South Atlantic Bight. Significant differences in the distribution of sponge species, sponge densities, and densities of sponge predators were documented across two adjacent reef habitats. Significant differences also occurred in the distribution of sponge chemical and structural defenses with chemical deterrence significantly greater in sponges associated with the habitat having higher predation intensity. Structural defenses, although effective in some instances, appear to …

Home Range, Reproduction, And Habitat Characteristics Of The Female Gopher Tortoise (Gopherus Polyphemus) In Southeast Georgia, Maggie Jo Mitchell

College of Graduate Studies: Theses & Dissertations

The relationship among female gopher tortoise home range, size, reproduction, habitat characteristics and season were studied for a two-year period (May 2002-May 2004) on Fort Stewart Army Reserve (FSAR) in southeast Georgia. Tortoises were studied in four sectors or regions on Ft. Stewart that contain the longleaf pine/wiregrass ecosystem. Vegetation characteristics were consistent between the different areas that tortoises inhabited. Soil types were similar between areas and consisted of Blanton, Bonifay, Fuquay, Albany Sand, Chipley, Echaw, Centenary, Stilson and Tifton soil types. Vegetation, temperature, and rainfall data were collected and compared with female home range. Reproductive data were collected for …

Selected Georgia High School Principals' Perceptions Of Student Diversity, Ronald James Wiggins

College of Graduate Studies: Theses & Dissertations

This study was conducted to identify Georgia high school principals' perceptions of student diversity. The student demographics of many Georgia school districts and schools are changing rapidly, while some school districts and schools have not experienced much, if any, demographic change. As a result, it is important for principals to be aware of what other principals perceive as advantages and disadvantages, the types of policies/programs that impact principals in regard to student diversity as well as to be familiar with artifactual evidence that may represent an appreciation or awareness of student diversity. The data displayed in this study was gathered …
