Development And Application Of A Gis-Based Long Island Sound Eelgrass Habitat Suitability Index Model, Jamie M.P. Vaudrey, Justin Eddings, Christopher Pickerell, Lorne Brousseau, Charles Yarish

Department of Marine Sciences

The primary objectives of the Eelgrass Habitat Suitability Index Model (EHSI Model) are to assist in the evaluation of sites being considered for eelgrass restoration efforts in the Long Island Sound (LIS) area and to identify areas where water quality issues reduce or eliminate the potential for natural eelgrass colonization. To achieve this goal, geospatial processing of data available from the Long Island Sound area was conducted using ArcGIS v10.0 including the 3D Analyst and Spatial Analyst extensions. The result is a series of maps presented in this report and a GIS-based model available for users to interact with the …

The General Qapp For Long Island Sound Volunteer Coastal Monitoring (With Adoption Form), Jamie M.P. Vaudrey, Kimberly Gallagher

Department of Marine Sciences

The General QAPP for Long Island Sound Volunteer Coastal Monitoring is designed to streamline the process of writing a QAPP for Monitoring Programs in the Long Island Sound area. This document does not replace guidance on developing a program and is not sufficient as a stand-alone document to guide the initial development and sample design process for a monitoring program.

Evaluation Of Current Community-Based Monitoring Efforts And Recommendations For Developing A Cohesive Network Of Support For Monitoring Long Island Sound Embayments., Jamie M.P. Vaudrey, Jamie Alonzo, Adrienne Esposito, Curt Johnson, Maureen Dolan Murphy, Charles Yarish

Department of Marine Sciences

This project focuses on Long Island Sound embayments and represents an exploration of the potential for coordination among community-based water quality monitoring groups, and coordination between community-based groups and data end users, including scientists and managers. Community-based monitoring groups represent a potential valuable source of water quality information. The development of standardized protocols, training methods and reporting procedures will serve to provide end users with the confidence necessary to utilize the data collected as part of community-based monitoring programs. Both groups of stakeholders stand to benefit from this type of coordination with the ultimate benefit being a healthier, better understood …

Transition Metals As Tools To Probe The Electronic Properties Of Porphyrinoids, Jillian Worlinsky

Chemistry Education Materials

This thesis describes in a number of separate chapters a range of studies that measure the variation of specific physical properties with structural modification of the macrocycles, with a particular focus also on using their coordinated metals as probes. Specifically, the transition metal ions are used as tools for interrogation of the electronic properties of porphyrins and pyrrole-modified porphyrins. With the aim of better understanding the electronic and structural factors that govern the optical responses, axial binding strengths, fragmentation patterns and carbonyl stretching frequencies of meso-tetraarylporphyrins, a rational design of pyrrole-modified metalloporphyrins with designed optical properties is derived.

Seasonal And Inter-Annual Atmospheric Trends Of Persistent Organic Pollutants In Groton, Ct, Lauren Rothermich

Honors Scholar Theses

Using data derived from one site in the global atmospheric passive sampling (GAPS) network, seasonal and inter-annual trends in concentrations for target pollutants were evaluated. Chemical physical properties such as Henry’s Law constant and the octanol-air partition co-efficient (Koa) were poor indicators of seasonality, but certain weather factors such as temperature and precipitation gave good correlations with contaminant concentration variability. Localized studies such as these will help add finer resolution to the study of global transport of persistent organic pollutants.

Biophysical Characterization Of Optimized Self-Assembling Protein Nanoparticles As A Malaria Vaccine, Sophia Walker

Honors Scholar Theses

Malaria is an infectious disease that affects several million individuals worldwide and is a significant international public health issue. While there is currently a malaria vaccine in phase III clinical trials, recent results demonstrate that it is only about 35% effective in reducing the incidence of the disease. The use of self-assembling protein nanoparticles (SAPNs) that display epitopes of the repeat sequence of the circumsporozoite protein of Plasmodium falciparum, the parasite that causes malaria, has been shown to elicit a strong immune response. This prototype has potential for further improvement by altering the epitope regions of the nanoparticles to …

Dirichlet's Theorem And Applications, Nicholas Stanford

Honors Scholar Theses

Dirichlet's theorem states that there exist an infinite number of primes in an arithmetic progression a + mk when a and m are relatively prime and k runs over the positive integers. While a few special cases of Dirichlet's theorem, such as the arithmetic progression 2 + 3k, can be settled by elementary methods, the proof of the general case is much more involved. Analysis of the Riemann zeta-function and Dirichlet L-functions is used.

The proof of Dirichlet's theorem suggests a method for defining a notion of density of a set of primes, called its Dirichlet density, …

Coordination Of Peroxide To The Cum Center Of Peptidylglycine Α-Hydroxylating Monooxygenase (Phm): Structural And Computational Study, Betty A. Eipper, Richard E. Mains

UCHC Articles - Research

Many bioactive peptides, such as hormones and neuropeptides, require amidation at the C terminus for their full biological activity. Peptidylglycine α-hydroxylating monooxygenase (PHM) performs the first step of the amidation reaction—the hydroxylation of peptidylglycine substrates at the Cα position of the terminal glycine. The hydroxylation reaction is copper- and O₂-dependent and requires 2 equiv of exogenous reductant. The proposed mechanism suggests that O₂ is reduced by two electrons, each provided by one of two nonequivalent copper sites in PHM (Cu_H and Cu_M). The characteristics of the reduced oxygen species in the PHM reaction and …

Preparation Of Organofluorine Compounds: Exploring Mono-, Di-, And Tri-Fluorination, Diandra M. Rudzinski

Master's Theses

Organofluorine compounds exhibit biological activity and have advantageous properties for drug design. Natural occurring fluorinated molecules are rare, demanding new synthetic methods for their preparation. A novel route to access trifluoromethyl ketones from Weinreb amide precursors is discussed. This is the first documented method for the use of the Ruppert-Prakash reagent, (trifluoromethyl)trimethylsilane, for the production of trifluoromethyl ketones from amide starting materials. This method is tolerant of aryl and alkyl substrates exhibited by their moderate to excellent yields. A discussion of the unusual reactivity of these amides, their selectivity for mono-trifluoromethylation, and other mono-, and di-fluorination attempts are reported.

Coastal Towns Adapt To Realities Of Climate Change, Christine Woodside
