A Regional Comparison Between The Seasonal Cycles Of The Western Irish Shelf And The Georges Bank, Gulf Of Maine Ecosystems: The Impact Of Physical Variability, Bronwyn Elizabeth Cahill

Open Access Dissertations

The seasonal response of two shelf ecosystems in the North Atlantic to fluctuations in climate variability is investigated. The Western Irish Shelf and the Georges Bank/Gulf of Maine are highly productive shelf systems (>300 gC m-2 y-1) located at mid-latitudes between the subpolar and subtropical gyres in the North Atlantic, making them interesting oceanographic transition zones where different water masses, flora and fauna mix. Their boundaries expand, contract and shift position in response to fluctuations in climate variability. In this study, positive and negative NAO scenarios are used as a proxy for climate variability in these regions. A three-dimensional …

The Virtual Eelgrass Meadow: A Simulation Of Zostera Marina L. Linking Physiology To Population Level Processes, Lora Anna Harris

Open Access Dissertations

The Virtual Eelgrass Meadow (VEM) was developed to link the population dynamics of eelgrass ramets with a mechanistic, physiological model of eelgrass growth that simulates rhizome elongation rates and new lateral shoot branching in two dimensions. The programming structure relies on an Individual Based Modeling approach emphasizing the botanical details of eelgrass ramet production and utilization of space. Growth rates depend on forced values of nitrogen loading and sediment sulfide concentrations, as well as the dynamic variables of light and temperature that also determine allocation of new production to leaves, rhizomes, or new lateral shoots. The pattern of lateral shoot …

Testing For Explosives: Forensics And Hazards, Suvarna Kishore Marimganti

Open Access Dissertations

Hair has been used extensively for detection of drugs. Hair analysis has also been shown to be quicker and less invasive than other methods used for analysis of environmental pollutants in biological systems. This study examined the ability of hair to pick up explosives [2, 4, 6-trinitro toluene (TNT), hexahydro-1, 3, 3-trinitro-s-triazine (RDX), pentaerythritol tetranitrate (PETN), ethylene glycol dinitrate (EGDN), 2, 4-dinitrotoluene (2, 4-DNT), nitroglycerine (NG), triacetone triperoxide (TATP) and diacetone diperoxide (DADP)] via vapor diffusion. The results showed that the sorption of explosive to black hair is significantly higher than brown, blond and bleached hair. The hair did not …

Effects Of Endocrine-Disrupting Chemicals On Fish Reproduction And Reproductive Indicators, Lesley Judith Mills

Open Access Dissertations

The central hypothesis tested in this dissertation is that endocrine-disrupting chemicals (EDCs) found in the aquatic environment disrupt reproductive processes in fish. To gain a broad perspective of existing evidence, a review of the current literature was conducted. From this literature review, the lack of a dependable method or indicator to assess reproductive fitness of fish in situ was identified as an outstanding need. In laboratory experiments, reproductive endpoints (egg production, fertility and viablity) were measured in the marine fish Tautogolabrus adspersus , or cunner, implanted with estrogens. Estrone and ethynylestradiol significantly reduced egg production in treated cunner at the …

Characterization Of The Interactions Between The Active Site Of A Protein Tyrosine Kinase And A Divalent Metal Activator, Xiaofeng Lin, Marina K. Ayrapetov, Gongqin Sun

Cell and Molecular Biology Faculty Publications

Background:

Protein tyrosine kinases are important enzymes for cell signalling and key targets for anticancer drug discovery. The catalytic mechanisms of protein tyrosine kinase-catalysed phosphorylation are not fully understood. Protein tyrosine kinase Csk requires two Mg²⁺ cations for activity: one (M1) binds to ATP, and the other (M2) acts as an essential activator.

Results:

Experiments in this communication characterize the interaction between M2 and Csk. Csk activity is sensitive to pH in the range of 6 to 7. Kinetic characterization indicates that the sensitivity is not due to altered substrate binding, but caused by the sensitivity of M2 binding …

Evidence-Based Research In Complementary And Alternative Medicine I: History, Francesco Chiappelli, Paolo Prolo, Olivia S. Cajulis

Senior Honors Projects

Contemporary Western medicine has witnessed a fragmentation of our conceptualization of the medical endeavor into ‘traditional medicine’ and ‘non-traditional medicine’. The former is meant to refer to the Western medical tradition, the latter encompasses both ‘complementary’ and ‘alternative’ medical practices. Complementary medicine complements conventional medical treatments, and alternative modes of medical interventions are meant to replace traditional Western medicine. Evidence-based research must be directed at establishing the best available evidence in complementary and alternative medicine. This paper is the first of a set of four ‘lectures’ that reviews the process of evidence-based research, and discusses its implications and applications for …

Pentaplot: A Software Tool For The Illustration Of Genome Mosaicism, Lutz H. Hamel, Olga Zhaxybayeva, J. Peter Gogarten

Computer Science and Statistics Faculty Publications

Background:

Dekapentagonal maps depict the phylogenetic relationships of five genomes in a visually appealing diagram and can be viewed as an alternative to a single evolutionary consensus tree. In particular, the generated maps focus attention on those gene families that significantly deviate from the consensus or plurality phylogeny. PentaPlot is a software tool that computes such dekapentagonal maps given an appropriate probability support matrix.

Results:

The visualization with dekapentagonal maps critically depends on the optimal layout of unrooted tree topologies representing different evolutionary relationships among five organisms along the vertices of the dekapentagon. This is a difficult optimization problem given …
