Marsan, David (University of Delaware, 2013)

One of the primary objectives of this thesis is to present an integrated study of the 210Pb and 210Po radioactive tracers, and assess their use as tracers for particle and trace element export from different estuarine ...
3D permeability characterization of fibrous media

Okonkwo, Kenneth (University of Delaware, 2010)

In Liquid Composite Molding (LCM) processes, a liquid resin is forced to flow through dry fibrous preform, usually fabrics, to impregnate it and create the composite part in net or near-net shape. The principal advantage ...
95 GHz silicon germanium low noise amplifier as front-end receiver for sparse aperture millimeter wave imaging

Wright, Andrew Alexander (University of Delaware, 2015)

Demand for the ability to navigate in degraded visual environments (DVE) such as dust, smoke, and fog, has lead the development of millimeter wave (mm-wave) real-time imaging systems. Millimeter wavelength radiation has ...
The abdominal fat contribution to adiposity in chickens divergently selected for fatness or growth: Cross-model elucidation and validation of gene expression

Resnyk, Christopher (University of Delaware, 2013)

The domestic chicken (Gallus domesticus) is an important global source of high-quality dietary protein and a widely used biological model. Decades of intensive genetic selection have established the remarkable growth rate ...
Abundance and size of the sea scallop population in the Mid-Atlantic Bight

Walker, Justin (University of Delaware, 2013)

The stock of the Mid-Atlantic Bight sea scallop fishery is assessed every year through the use of various dredging and imaging techniques. The sustainability of the fishery depends on the proper setting of the yearly catch ...
Abundance of the Asian shore crab Hemigrapsus sanguineus in and adjacent to the Delaware Bay: evidence of invasive crash and return of native species

Schab, Corey (University of Delaware, 2013)

The Asian shore crab Hemigrapsus sanguineus has been introduced to multiple rocky habitats outside its native range and is considered an invasive species on the East Coast. The Delaware Bay region represents one of these ...
Abundance, diversity, and activity of ammonia-oxidizing prokaryotes in the coastal arctic ocean in summer and winter

Christman, Glenn (University of Delaware, 2009)

Ammonia oxidation, the first step in nitrification, is performed by certain Betaand Gammaproteobacteria and mesophilic Crenarchaea to generate metabolic energy. Ammonia monooxygenase (amoA) genes from both Bacteria and ...
Acculturation, diet and psychological health of Asian international students at the University of Delaware

Jiang, Heng (University of Delaware, 2015)

Background: Accumulating evidence showed that immigrants change their diet and experience various psychological problems in acculturation process. International students in United States are increasing rapidly and more ...
Accumulation of sediment and radionuclides in tidal marshes of the Murderkill River Estuary, Delaware

Stuart, Dack (University of Delaware, 2010)

This thesis examines patterns and rates of sediment accumulation and tidal marsh accretion in the Murderkill River estuary, Delaware, with special emphasis placed on changes in accumulation rates and sediment physical ...
Accuracy and convergence of the Asymptotic Single Risk Factor formula in a large credit portfolio

Houser, Madelyn R. (University of Delaware, 2016)

According to international banking standards, all financial institutions must classify the risks associated with the credit portfolios they hold. Mathematical approximations of default distributions are among the most ...
Acoustic wave propagation and intensity fluctuations in shallow water 2006 experiment

Luo, Jing (University of Delaware, 2016)

Fluctuations of low frequency sound propagation in the presence of nonlinear internal waves during the Shallow Water 2006 experiment are analyzed. Acoustic waves and environmental data including on-board ship radar images ...
The acquisition of relative clause structures in L2 French

Dickens, Kayla Raye (University of Delaware, 2018)

Anecdotal evidence as well as research with second-language French learners (for example, Hollerbach 1994 and Walz 1981a) show that learners struggle to properly acquire the complex system of relativization in French. This ...
"An act apart": tea-drinking, play and ritual

Ranalli, Kristina (University of Delaware, 2013)

Studies of tea-drinking emphasize gentility as a fundamental value in early American culture and primarily examine the eighteenth century. But tea continued to be consumed widely in the nineteenth century, and the manufacture ...
Activity and abundance of bacterial groups in the Sargasso Sea and Mid-Atlantic Bight

Grim, Sharon (University of Delaware, 2011)

Microbial communities are essential to the processing of dissolved organic matter and nutrients in the ocean. Molecular methods are used to assess phylogenetic structure and activity within marine bacterial populations. ...
Acute effect of cocoa on vascular function in chronic kidney disease patients: a pilot study

Ferreira, Courtney (University of Delaware, 2014)

Chronic kidney disease (CKD) is associated with an increased prevalence of cardiovascular disease (CVD) and these individuals often die of CVD before reaching end-stage kidney disease. Dysfunction of the endothelial lining ...
Adaptations of the shoulder to overhead throwing in youth athletes

Astolfi, Matthew (University of Delaware, 2013)

Introduction: Due to the high repetition and force associated with overhead throwing anatomical adaptations are observed in elite and professional level baseball athletes however, little is known about their origin and ...
Adaptive management strategies on the Chesapeake Bay regarding TMDLs

Cunningham, Alexis (University of Delaware, 2018)

In December 2010, the United States (U.S.) Environmental Protection Agency (EPA) released a cleanup plan for the Chesapeake Bay known as the Total Maximum Daily Load (Bay TMDL). The Bay TMDL document established nutrient ...
Additive manufacturing of graded dielectrics

Roper, David A., Jr. (University of Delaware, 2014)

The ability to fabricate electromagnetic (EM) materials with graded dielectric properties would benefit a variety of interesting applications, such as low profile antennas, antireflective surfaces, passive beam formers ...
Additive manufacturing of RF absorbers

Mills, Matthew S. (University of Delaware, 2016)

The ability of additive manufacturing techniques to fabricate integrated electromagnetic absorbers tuned for specific radio frequency bands within structural composites allows for unique combinations of mechanical and ...
Adjustment of external imbalances: Does the exchange rate matter? -- evidence from Brazil, China and India

Xie, Ruizhi (University of Delaware, 2011)

This thesis investigates the nature of the dynamic relationship between external balances and exchange rate dynamics in a macroeconomy. Specifically, this study focuses on how various measures of external balances serve ...
