Spatial Analyses And Repletion Of Gargathy Coastal Lagoon, Loreto Herraiz Gomez

OES Theses and Dissertations

Coastal lagoons and bays vary in shape and size in response to antecedent topography, geologic processes and sea level rise. Variations in shape and environmental conditions of coastal basins are believed to influence the distribution of benthic sub-environments and the exchange of water with the ocean and other adjacent coastal systems. Gargathy Inlet and its coastal lagoon vary spatially from the inlet, where the greatest depths are observed, to the mainland, dominated by shallow intertidal areas, colonized by marsh. Hypsographic and hydro-hypsographic analyses of Gargathy's coastal lagoon were the primary techniques applied to understand the relative distribution of the benthic …

Induction Of Winter Breeding In Small Mammals By 6-Mboa, Robert K. Rose, Roger K. Everton, Gregory E. Glass

Virginia Journal of Science

A plant-derived cyclic carbamate, 6-methoxybenzoxazolinone (6-MBOA), is

known to initiate reproductive activity in Microtus montanus. We studied

overwintering populations of four other rodent species, and observed increased

reproduction in experimental populations of two herbivorous species, Microtus

pennsylvanicus and Sigmodon hispidus, but not in two omnivorous species,

Oryzomys palustris and Mus musculus. These results suggest that low

concentrations of 6-MBOA may trigger seasonal breeding primarily in

herbivorous small mammals.

Aerial And Satellite Image Processing Applications, Srinivas K. Jakkula

Electrical & Computer Engineering Theses & Dissertations

Aerial and satellite images are used extensively in many trip and mapping software packages, such as Google Earth etc. Aerial images differ significantly due to the variations in atmospheric clarity, atmospheric layer density, humidity, temperature, and season under which the aerial images are captured. Among the issues in effective utilization of aerial images, color tone discrepancy is the inconsistency in brightness, saturation, or color balance between images representing adjacent areas, causing adjacent areas appear significantly different that would otherwise be similar. Aenal images are also routinely used as ground textures to simulate Earth surface and 3D features on Earth in …

The Development Of Genetic Algorithm For The Prediction Of Ship Motion From Wave Radar Data, Sumanth Tirumala Vangipuram

Electrical & Computer Engineering Theses & Dissertations

Genetic Algorithms represent a model of natural process based on the Darwinian principle of evolution. Genetic algorithms are used to solve optimization problems by generating a set of possible solutions and determining which of these solutions most closely match the desired result. The Genetic Algorithm (GA) initially generates a random set of possible solutions, or populations, determines which members of the population are most desirable, and calculates better solutions by implementing genetic operations such as reproduction, cloning, and mutation. Problems where the evaluation of a solution is computationally simple enable the GA to search a vast search space. One of …

“I Hope You Never See Another Day Like This”: Pedagogy & Allegory In “Post 9/11” Video Games, Marc A. Ouellette

English Faculty Publications

Although critics and scholars have considered the extent to which the terror attacks of 11 Sept. 2001 influenced subsequent media productions, video games comprise a largely unexamined form. This oversight also applies to related forms of media production and among those who study video games is in part attributable to the ongoing debate regarding the relationship(s) between narrative and play. Even so, as early as 1997, JC Herz was investigating the role of video games in the military-entertainment complex. That said, the focus of this paper will not be the obvious games which draw settings and plots directly from the …

How Personal Nostalgia Influences Giving To Charity, Altaf Merchant

Theses and Dissertations in Business Administration

Charitable organizations in the U.S. have found it increasingly difficult to raise funds from donors. With a decline in the number of donors and with the number of charitable organizations increasing, there is a greater need than ever to engage the giver and encourage him/her to increase their giving to charitable organizations. NPOs (not-for-profit organizations) can facilitate this engagement through the identification of emotional constructs that can drive donor commitment to the NPO and increase charitable giving. In a recent study, Sargeant et al. (2006) have shown that charities which engage the giver emotionally are able to create stronger commitment …

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs

Dental Hygiene Theses & Dissertations

Placement of pit and fissure dental sealants is an effective therapy for tooth decay prevention and is widely accepted as a standard of care throughout the United States. Pit and fissure dental sealants (sealants) are manufactured using the resin component of composite dental materials, formed by reacting glycidyl methacrylate with bisphenol A. Bisphenol A (BPA) is a hormonally active, synthetic chemical that is part of a broad group of chemicals known as endocrine disrupting compounds, xenoestrogens, which mimic bioactivity of estrogen. This study measured BP A in saliva and blood after the placement of a widely used, pit and fissure …

Italy And Italians Through American Eyes, 1861-1881, Dennis M. Bench

History Theses & Dissertations

American perceptions of Italy and Italians between 1861 and 1881 were characterized by competing and conflicting images. These two decades in the late­ nineteenth century demonstrated the transitional nature of American attitudes towards Italians as contact between the two peoples increased. American travelers went to Italy initially to recreate the journeys of educated Europeans of the Grand Tours of the eighteenth century. By the 1860s this style of travel was on the decline to be replaced by traveling based on exploring the "real" Italy. However, the two styles overlapped and resulted in conflicting and complementary images. In part this was …

Pge2 Receptor Subsets Mediate Hcg Regulation Of The Plasminogen Activator/Plasmin System In Primate Periovulatory Follicles, Nune Markosyan

Theses and Dissertations in Biomedical Sciences

Elevated follicular prostaglandin E2 (PGE2) levels are necessary for follicle rupture during ovulation. As the degradation of the follicle wall requires proteolysis, it was hypothesized that regulation of proteolysis by gonadotropins is PGE2 mediated.

There are four PGE2 receptors: EP1, EP2, EP3 and EP4. To determine which PGE2 receptors are present in monkey periovulatory follicles, granulosa cells and whole ovaries were collected 0, 12, 24, and 36 hours after administration of an ovulatory dose of human chorionic gonadotropin (hCG), or 36 hours after hCG from monkeys that received the prostaglandin (PG) synthesis inhibitor celecoxib. All EP receptor mRNAs were present …

Biology-Inspired Approach For Communal Behavior In Massively Deployed Sensor Networks, Kennie H. Jones

Computer Science Theses & Dissertations

Research in wireless sensor networks has accelerated rapidly in recent years. The promise of ubiquitous control of the physical environment opens the way for new applications that will redefine the way we live and work. Due to the small size and low cost of sensor devices, visionaries promise smart systems enabled by deployment of massive numbers of sensors working in concert. To date, most of the research effort has concentrated on forming ad hoc networks under centralized control, which is not scalable to massive deployments. This thesis proposes an alternative approach based on models inspired by biological systems and reports …

Microtextures Of Cyanobacterial Mats In Siliciclastic Sedimentary Environments (Modern & Ancient): Applications To The Search For Life On Mars, Dina M. Bower

OES Theses and Dissertations

The current Mars Exploration Rover Program (MER) is one of NASA's most successful missions. The aim of the MER is to explore for possible life on the surface of Mars. My thesis developed new methods of how to detect and to identify microbial mats in siliciclastic sediments (modern and ancient), and to make recommendations on the applicability of MISS as biosignatures. Predominantly, I employed instrumentation portable by future rovers. To search for life on other planets, we need to have information on how this life might look. Most astrobiological studies therefore focus on Earthly analogues of life and its habitats. …

In Vivo Murine Melanoma Tumor Responses To Nanosecond Pulsed Electric Field Treatment, Xinhua Chen

Theses and Dissertations in Biomedical Sciences

High intensity nanosecond pulsed electric fields (nsPEF) were applied to melanoma tumors to observe functional and structural biological changes and to investigate the possible molecular mechanisms responsible. An animal model was set up by injecting B16F10 mouse melanoma cells into SKH-1 mice. A treatment (Tx) of 100 pulses: 300 nanosecond duration; 40 kV/cm field strength; at 0.5 Hz rate were delivered to melanoma tumors in 120 mice. The nsPEF Txcaused tumor self-destruction with sharply decreased cell volumes and shrunken nuclei. The apoptotic biochemical tests confirmed nsPEF Tx induced apoptosis in a time-dependent manner. Examination of gross vessel and micro-vessel density …

A Phylogeny Of The Snappers (Lutjanidae; Percoidei) Inferred From Cytochrome B Sequence Data, Matthew R. Semcheski

Biological Sciences Theses & Dissertations

The Lutjanidae are economically and ecologically important fishes commonly known as snappers. A morphological study of Lutjanidae concluded that it contained four subfamilies and that together with the family Caesionidae, form the superfamily Lutjanoidea. Although this view was supported elsewhere in the literature, it was later contradicted, treating the caesionids as members of the Lutjanidae. In order to infer a phylogeny of genera within Lutjanidae, the complete cytochrome b gene (1140bp) of 21 lutjanid taxa was sequenced and analyzed along with 19 lutjanid, caesionid, and outgroup sequences obtained from GenBank. Data were analyzed for base composition stationarity and saturation. Phylogenetic …

Nanosecond Pulsed Electric Fields Induce A Mitochondria-Independent Apoptosis In B16f10 Melanoma Cells In Vitro, Wentia Elissa Ford

Theses and Dissertations in Biomedical Sciences

Nanosecond pulsed electric fields (nsPEFs) are ultra-short pulses that induce direct electric field and biological effects that initiate apoptosis. Here the application of ten 300ns pulses ranging in electric fields from 12kV/cm-60kV/cm was administered to determine the effects on B16F10 melanoma cells evaluated by in vitro studies. Initial application of nsPEFs demonstrated apoptosis induction in an electric field- and pulse number-dependent manner measured by caspase activation that correlated with decrease in cell viability 24hr post pulse. In addition caspase activity was shown to be independent of calcium mobilization though ions may play a part in other aspects of apoptosis. The …

Bones To Read: An Interpretation Of Forensic Crime Fiction, Ingrida Povidiša

Reconstruction: Studies in Contemporary Culture

The anthropological forensic crime fiction is a detective genre which is primarily concerned with investigating human bodies. In the hermeneutical process of reading the bones (i.e. studying, interpreting, understanding, embodying), the most enduring record carrier of one's individuality, supported by a rhizoid network of scientific disciplines, the anonymous corpse becomes a personalized victim. The present discussion is based on the novels of Kathy Reichs. Specific characteristics of the materiality and mediality of representation can be traced through a juxtaposition of Reichs' novels with the serial Bones (Twentieth Century Fox, 2005 - Present) and the novel by Max Allan Collins Bones …

Purpose. This study was conducted to determine the effects of 5 different finger rest positions: opposite arch, standard intraoral, basic extraoral, cross arch, and finger on finger on the muscle activity of 4 forearm muscles (extensor carpi radialis longus, flexor carpi ulnaris, biceps brachii, and pronator teres) during a simulated periodontal scaling experience.

Methods. A convenience sample of 32 consenting senior dental hygiene students who met inclusion criteria participated. Using a 4 x 5 counter-balanced research design, each participant used a Gracey 11/12 curet to scale one cc of artificial calculus from first permanent molar typodont teeth (#3,14,19,30). Five different …

Compartmentalizing The Other: Nineteenth-Century Englishwomen, Travel, And English Identity, Amanda E. Williams

History Theses & Dissertations

The nineteenth century was an age of travel. The English traveled the globe for a variety of reasons. When not traveling for military, political, religious, or scientific reasons, they also traveled a great deal simply for pleasure. Regardless of reason, travel brought the English into contact with the Other. As a construction, the Other became an important part of English identity.

Englishwomen were particularly famous for travel. Although they were disenfranchised Others themselves in English society, Englishwomen did not identify with the Other they encountered in travels, but rather chose enfranchisement in an elite "imagined" England. This community (or the …

Congestion Mitigation In Wireless Sensor Networks Using Single-Hop Backpressure Algorithm, Vijay Shekar Mangilipalli Gangu Sham

Electrical & Computer Engineering Theses & Dissertations

Wireless sensor networks consist of a group of small components with limited resources allocated to sense the environment and transmit data to the user or interpreter. This concept is technically evolved from Sensors that are basically used to sense the environment around and collect data based on the sensing application incorporated in them. An extension to functionality of the sensors leads to the concept of sensor networks, where, in addition to gathering information at individual sensors, the data is processed and transmitted to a central station or Base station. This concept of transmitting the information from one node to the …

Prostate Cancer Patients’ Physiological Responses To Coloring A Mandala Or Working A Maze Puzzle, John Daniel Lorance Jr.

EVMS School of Health Professions Theses & Dissertations

Prostate cancer presents the patient with numerous stressors including diagnosis, treatment, rehabilitation, possible income hardship, and social implications. The purpose of the present study was to examine the effects of a known stress-reducing art task on levels of stress, anxiety and immunity. Four participants diagnosed with prostate cancer were randomly assigned to either a control group that worked a maze puzzle or an experimental group that colored a pre-designed mandala. Pretest-posttest measurements included psychological and physiological indicators of stress, anxiety and immunity. In summary, coloring a pre-designed mandala enhanced immunity and significantly lowered levels of anxiety. This randomized, controlled investigation …

An Exploration Of The Effects Of An Arm Movement Intervention Upon Artwork: Implications For Art Therapy, Alicia K. Hurst

EVMS School of Health Professions Theses & Dissertations

Why have pioneers of art therapy and modern art therapists discussed the importance of body movement in art therapy and yet not one study has been conducted to test its benefits? How can an art therapist overlook body movement in an art therapy session when one must move in order to create art? Observing the need for more research in this area, this study explored how body movement may affect art using one of Florence Cane’s (1951/1983) arm exercises and the scribble technique.

Four adult volunteers were individually videotaped while completing the scribble technique, then the arm exercise, and then …

Art Therapy With Native American Cancer Survivors: An Observation Of Nonverbal Communication Styles, Kathryn Dengler

EVMS School of Health Professions Theses & Dissertations

There is a high morbidity rate among Native American women with breast cancer. Research suggests that traditional beliefs in addition to miscommunication within the healthcare setting may affect the treatment Natives receive. This study observed the nonverbal communication patterns of ten Native American cancer survivors participating in an art psychoeducational workshop. Mapping techniques and situational analysis were used to observe nonverbal communication patterns during the workshop. It was hypothesized that Native Americans would use nonverbal cues more readily than verbal communication.

The results of the study supported the hypothesis. Nonverbal cues were the primary means of communication throughout the workshop. …

Integrating Rational Emotive Behavioral Therapy Into Art Therapy: Depression Treatment In Juvenile Justice Settings, Elizabeth Illig

EVMS School of Health Professions Theses & Dissertations

This single case mixed methods research study integrated Rational Emotive Behavioral Therapy (REBT) into art therapy in the treatment of incarcerated adolescents experiencing a depressed mood. The review of the literature focused on depression treatment as approached by REBT practitioners and art therapists, and revealed that an integration of these approaches had not been previously attempted. Before the study commenced the Reynolds Adolescent Depression Scale-2 was administered to both participants. Then individual REBT-enhanced art therapy sessions were conducted. After the conclusion of these sessions the RADS-2 was re-administered, an exit interview conducted, and a formal analysis of the artwork was …

A Content Analysis Of Acculturating Hispanics’ Artwork: Implications For Art Therapy, Sarah Bufogle

EVMS School of Health Professions Theses & Dissertations

Research in art therapy and other mental health fields on Hispanics is limited. In an attempt to further understand Hispanics and the impact of the acculturation process, this study explores similarities and/or differences between the content of drawings of Hispanics who have lived in the United States for 7 years or less and non-Hispanics. Participants consisted of 9 Hispanics and 11 non-Hispanics. A content analysis of the Free Choice Drawing was utilized to determine graphic differences between drawings of both groups. It was hypothesized that there might be considerable visual differences between drawings by acculturating Hispanics and by non-Hispanics.

Transmission Of Panulirus Argus Virus 1 (Pav1) And Its Effect On The Survival Of Juvenile Caribbean Spiny Lobster, Mark J. Butler Iv, Donald C. Behringer Jr., Jeffrey D. Shields

Biological Sciences Faculty Publications

The Caribbean spiny lobster Panulirus argus, an important fisheries species, is host to Panulirus argus virus 1 (PaV1), a lethal, unclassified virus-the first found in any species of lobster-prevalent in juvenile lobsters. We describe a series of laboratory experiments aimed at assessing the likely modes of disease transmission, determining the survival of lobsters relative to each transmission pathway and identifying potential alternate hosts. Given evidence for lower prevalence of PaV1 in large lobsters, the effect of lobster size on susceptibility was also examined. Results demonstrated that PaV1 can be transmitted to juvenile lobsters via inoculation, ingestion of diseased tissue, contact …
