Trivalent Metal Complexation Of Pendant-Armed Cross-Bridged Cyclams, Han Wang

Master's Theses and Capstones

Radiopharmaceuticals are radioactive compounds which are used in radiotherapy or diagnosis. They have attracted a great deal of attention over the last decades for molecular imaging. Coordination chemistry also plays an important role in designing metal-based radiopharmaceuticals. A novel class of tetraazamacrocycle ligands where two non-adjacent nitrogens are bridged by an ethylene cross-bridge show good thermodynamic stability and high kinetic inertness in their metal complexes. Seven trivalent metal (Y3+, La3+, Ga3+, In3+) complexes of cross-bridged ligands have been synthesized and characterized. Two vanadyl complexes were prepared as well. All metal complexations have been investigated under microwave-assisted conditions. Both Ga-CB-TE2P and …

The Influence Of Stocking Density And Acoustic Conditioning On The Behavior And Growth Of Atlantic Cod, Gadus Morhua, Daniel Ward

Master's Theses and Capstones

The goal of experiment one (Chapter One) was to determine if stocking density had an influence of the swimming behavior and spatial distribution of adult cod that were being raised in an aquaculture cage at the University of New Hampshire's Coastal Marine Laboratory. Acoustic telemetry and underwater video were used to quantify the behavior and distribution of cod that were stocked at four densities (5, 10, 25 and 45 kg/m³). At the lowest density (5 kg/m³) cod remained deep in the cage and spent 64.3 +/- 0.8% of their time below 1.80m (of a 2.70m cage). This contrasts to the …

Evaluation Of Post Harvest Conditions Contributing To Attacks By The Red Turpentine Beetle, Dendroctonus Valens Leconte At The Massabesic Experimental Forest In Southern Maine, Garret D. Dubois

Master's Theses and Capstones

Silvicultural management of Pinus strobus L. runs the risk of damaging residual trees and can increase the probability of attack from damaging insects, including the common bark beetle Dendroctonus valens Le Conte. Considered a secondary pest, it is possible that D. valens is capable of economic impacts such as the downgrading of logs and lumber due to defect and blue-stain. To assess post harvest conditions that contribute to the probability and severity of D. valens attacks in Pinus strobus, stand and tree characteristics were sampled in four silvicultural treatments and one control site in southern Maine. Results showed that clearcuts …

The Association Between Parenting Style And Life Satisfaction In Adulthood, Stephanie Caras

Master's Theses and Capstones

This research examined the association between parenting style and life satisfaction in adulthood (N=112). Participants responded to an online survey, called the Parenting Style and Life Satisfaction Survey, which included questions pertaining to parenting style experienced in childhood, parenting style used in adulthood, and levels of life satisfaction. A chi-square test was conducted to determine if there was a relationship between parenting style experienced in childhood and the adult's own parenting style. Analysis of variance tests were conducted to determine how parenting style experienced in childhood was connected to life satisfaction in adulthood and how the adult's parenting style was …

Gender Bias In The Legal Field: Experiences Of Female Attorneys And Law Students, Jessie L. French

Master's Theses and Capstones

This study examines the experiences of female attorneys and law students with respect to gender bias. Contemporary evaluations indicate that while women comprise approximately 50% of the job force, they are significantly underrepresented in management positions and continue to be paid less than men; this is especially true in the legal field. Thirty-five in-depth interviews were conducted, 25 with women who had obtained a juris doctorate and 10 with female law students. Women discussed their experiences in the legal field relative to law school, expectations for their careers, media influences, gender discrimination and harassment. Qualitative analysis revealed that pregnancy was …

Measuring Paralytic Shellfish Toxins In Mussels From New Hampshire Coastal Waters Using Zwitterionic Hydrophilic Liquid Chromatography/Electrospray Mass Spectrometry, Lee Lee Chung

Master's Theses and Capstones

A liquid chromatography/mass spectrometry method (LC/MS) has been adapted from the literature to provide a rapid, direct and highly sensitive routine assays for several Paralytic Shellfish Poisoning (PSP) toxins, with detection limits in the ppb range for STX and its analog neosaxitoxin (NEO) and decarbamoyl saxitoxin (dcSTX). A high throughput sample clean-up aided in reducing the effects of the matrix. Method validation and stability studies have been performed to show that reliable results are produced by this LC/MS method. The LC/MS method was found to supplement the mouse bioassay with the ability to determine the levels and specific types of …

Bio-Inspired Log-Polar Based Color Image Pattern Analysis In Multiple Frequency Channels, Xiaolu Li

Master's Theses and Capstones

The main topic addressed in this thesis is to implement color image pattern recognition based on the lateral inhibition subtraction phenomenon combined with a complex log-polar mapping in multiple spatial frequency channels. It is shown that the individual red, green and blue channels have different recognition performances when put in the context of former work done by Dragan Vidacic. It is observed that the green channel performs better than the other two channels, with the blue channel having the poorest performance. Following the application of a contrast stretching function the object recognition performance is improved in all channels. Multiple spatial …

Using Pentaploids As Tools For Studying Genomic Composition And Allele Transmission Patterns In Octoploid Fragaria, Elizabeth Poulsen

Master's Theses and Capstones

A unique pentaploid population of Fragaria (strawberry) was developed to gain insight into octoploid genome composition and allele transmission patterns. This population was produced by crossing representatives of two divergent subspecies of octoploid F. virginiana and then by crossing an octoploid hybrid plant with diploid F. vesca. To enable examination of allele transmission patterns, the intergenic region of the gRGA1-Subtilase gene pair locus was amplified, and PCR products were cloned, sequenced, and compared to define the allele composition of the hybrid octoploid. The sequencing data revealed three distinct major haplotypes and additional subtypes. The pentaploids were genotyped utilizing the FEL-CAPS …

Impacts Of Suburbanization On Food Web Stoichiometry Of Detritus-Based Streams, Nathaniel Burr Morse

Master's Theses and Capstones

Higher non-point source nutrient inputs are one of many impacts associated with the "urban stream syndrome". Research on how non-point source pollution affects the stoichiometry of urban stream food webs has received little attention, however. This study quantified food web stoichiometry in nine headwater, detritus-based streams draining forested or suburban watersheds in northeastern, coastal Massachusetts.

While this study suggests that suburbanization can affect in-stream nutrient recycling by consumers, research that quantifies changes to biomass of different in-stream compartments is needed to calculate the extent of such impacts on suburban stream ecosystems.

Exposure To Polybrominated Diphenyl Ethers (Pbdes) Suppresses The Release Of Pro-Inflammatory Products By Alveolar Macrophages In Vitro, Stephen R. Hennigar

Master's Theses and Capstones

Endocrine disrupting chemicals have adverse effects on immune function that may result in respiratory conditions. Inhalation of dust is a major route of exposure to PBDEs; however, the impact of PBDEs on the immune response is unclear. The objective of this in vitro study was to determine the impact of PBDEs on the release of pro-inflammatory cytokines by activated alveolar macrophages. Porcine alveolar macrophages were grown in RPMI growth media supplemented with 10% porcine serum and incubated for 24-hours. After 24-hours, cells were activated by inoculation with PMA. In addition to PMA, different concentrations of the PBDE mixture DE-71 were …

Age And Age Structure Of An Invasive Plant, Lythrum Salicaria, Kimberly L. Therrien

Master's Theses and Capstones

My objective was to determine whether purple loosestrife (Lythrum salicaria L.) individuals could be aged using the pattern of ramet production. Assuming current year loosestrife ramets produce new basal ramets only in the following year, plant age could be estimated by counting ranks of sequentially produced ramets. I found that in four New Hampshire wetlands the assumptions of the method were generally met, although some ramets were not produced sequentially. Using ramet counts I was able to estimate minimum age for individuals in each of the four populations. All populations were dominated by individuals > 1 year old. I tested whether …

The Effects Of Chlortetracycline, Lasalocid, And The Combination On Growth, Health, Apparent Total Tract Nutrient Digestibility, And Nitrogen Retention Of Post-Weaned Dairy Heifers, Kelly Anne Greenbacker

Master's Theses and Capstones

The experiment compared the effects of chlortetracycline (CTC), lasalocid (L), and the combination (LCTC) on dairy heifers. Forty calves, 12 wk of age, were assigned to control (C), L (1 mg/kg BW/d), CTC (350 mg/d), or LCTC. Individual DMI was measured daily. Skeletal measures, BW, BCS, blood urea N and glucose concentrations were measured weekly. Calves received an external marker to estimate apparent total tract nutrient digestibilities. Total collection of urine was obtained from 20 calves to determine N retention. The DMI was higher (P=0.01) for CTC versus L and C, and DMI was lower for L versus LCTC. ADG …

Improving Efficiencies And Modeling A Cyclic Suspended Ion Exchange (Six(C)) Drinking Water Pre-Treatment Systems, Owen P. Friend-Gray

Master's Theses and Capstones

This research focused on three primary components of the Suspended Ion eXchange (SIX(c)) process developed by PWN Water Supply Company North Holland. The first step focused on the resin regeneration procedure. It was shown that the current system could be improved and that reducing the complexity of the system simplified the process and increased the regeneration efficiency. The second step focused on the resin tank contactor hydraulics. It was determined that for the sequential completely mixed reactor design at PWN, high flows with low mixing speed of the overhead paddle mixers led to the most efficient hydraulic regime. The third …

Isotopic Analysis Of Arctic Ground Squirrel Tissues And Potential Food Sources, Julee Shamhart

Master's Theses and Capstones

Given limited knowledge of the food sources of Arctic ground squirrels, an important arctic prey species, it is difficult to predict the implications of changes in food source availability that could result from climate change. I hypothesized that Arctic ground squirrels at two colonies, Atigun and Toolik, would have similar feeding habits and mushrooms would contribute to their diet The Arctic ground squirrels at Toolik had significantly higher del15N (3.7 per mill difference) and del13C values (1.3 per mill difference) than those at Atigun. Mixing models indicated that the signatures observed in the Atigun hair could result from a combination …

Marine Benthic Habitat Mapping Of Muir Inlet, Glacier Bay National Park And Preserve, Alaska With An Evaluation Of The Coastal And Marine Ecological Classification Standard Iii, Luke D. Mitchell, Guy R. Cochrane, Lisa Etherington, Ross D. Powell, Larry A. Mayer

Center for Coastal and Ocean Mapping

Seafloor geology and potential benthic habitats were mapped in Muir Inlet, Glacier Bay National Park and Preserve, Alaska, using multibeam sonar, ground-truth information, and geological interpretations. Muir Inlet is a recently deglaciated fjord that is under the influence of glacial and paraglacial marine processes. High glacially derived sediment and meltwater fluxes, slope instabilities, and variable bathymetry result in a highly dynamic estuarine environment and benthic ecosystem. We characterize the fjord seafloor and potential benthic habitats using the Coastal and Marine Ecological Classification Standard (CMECS) recently developed by the National Oceanic and Atmospheric Administration (NOAA) and NatureServe. Substrates within Muir Inlet …
