Multiscale Monte Carlo study of epidermal growth factor receptor diffusion and dimerization

Collins, Stuart (University of Delaware, 2009)

The ErbB family of receptors is dysregulated in a number of cancers, and the signaling pathway of this receptor family is a critical target for several anti-cancer drugs. Therefore, a detailed understanding of the ...
Analysis of seafood consumer characteristics

Schwenk, Elizabeth (University of Delaware, 2009)

Background: Seafood is an excellent source of essential omega-3 polyunsaturated fatty acids (PUFA) in the diet. The 2005 Dietary Guidelines for Americans (DGA) advocate the intake of two servings of fish per week noting ...
Estimating habitat carrying capacity for American black ducks wintering in Southern New Jersey

Cramer, Dane (University of Delaware, 2009)

Midwinter waterfowl survey (MWS) data indicates a long-term decline in the number of wintering American black ducks (Anas rubripes), potentially due to the habitat limitations. My objectives were to (1) estimate the current ...
Examining infants’ cortisol responses to laboratory tasks among children varying in attachment disorganization: stress reactivity or return to baseline?

Bernard, Kristin (University of Delaware, 2009)

Cortisol is a hormone involved in mounting a stress response in humans. During infancy, however, cortisol appears to be relatively unresponsive to a number of stressors. This developmental period of cortisol hypo-reactivity ...
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 ...
Growth and organ differences between chicken lines selected for divergent growth rates

Feierstein, Erika (University of Delaware, 2009)

Selecting chicken for enhanced meat production has altered the relative growth of organs in modern broiler lines, when compared with heritage lines. In this five week study, we compared the growth and feed efficiency of a ...
Fate, transport, and bioavailability of arsenic in manured and contaminated soils of Delaware

Gardner, Sheila (University of Delaware, 2009)

Over the past several years, trace element contamination, specifically arsenic (As), in soils and water has become an alarming environmental issue. All metal/metalloids are potentially hazardous at some concentration ...
Mechanical model of an early stage osteoarthritis

Chiravuri, Venkat (University of Delaware, 2009)

Osteoarthritis (OA) is a common degenerative disease which affects the articular surfaces and adjacent tissues of human synovial joints. More than 20 million Americans are estimated to have OA. OA changes the entire ...
Does consumer willingness to pay change over time in response to food scares?

Dillaway, Robin (University of Delaware, 2009)

Using poultry as a case study, this research uses experimental auctions to examine the short and longer term impacts of media information on consumer behavior. Adult subjects were presented with negative food safety ...
Tactile feedback of steer-by-wire agriculture machines

Xu, Hong (University of Delaware, 2009)

The implementation of control systems in the automotive industry enabled by electronic actuators is referred to as X-by-wire technique. The application of steerby- wire technique in agriculture machine simplifies ...
Caregiver’s history of depressive symptoms and child affect expression in the context of structured interaction tasks

Vahlsing, Julia (University of Delaware, 2009)

Reduced positive emotionality (PE) in children of depressed mothers has been identified as a risk factor for later depression. In the current study we explored the associations between maternal history of depression, ...
Implementation of a computational model for random directional seas and underwater acoustics

Bayindir, Cihan (University of Delaware, 2009)

Acoustic wave propagation in the ocean is an old and interesting problem. In the literature the problem of interaction of acoustic waves with the ocean surface has drawn the attention of many researchers. This interaction ...
Design tutorial and comparative analysis of printed circuit board production softwares for microcontroller & FPGA-based systems

Hoover, Ryan (University of Delaware, 2009)

Printed Circuit Board design and implementation is a research topic most any company or group manufacturing electronic devices must address. There are issues in every aspect of design, ranging from schematics to pad ...
Observing changes in gender and sexuality in slasher film franchises

Newby, Brian (University of Delaware, 2009)

The connection between horror and gender is nothing new. The context of psychoanalytic feminist film theory lends itself to the discussion of gender within the films themselves, but treats the films as a universe in and ...
The role of race and caretaker substance abuse in child protective services responses to child abuse reports

Ralston, Kevin M. (University of Delaware, 2009)

It is believed that approximately 30% of the child maltreatment cases involve a caretaker with a substance abuse problem. Previous literature has established a link between caretaker substance abuse and child maltreatment. ...
The effect of iron status on the risk for developing cardiovascular disease in the healthy aging in neighborhoods of diversity across the life span (HANDLS) study sample

Olesnevich, Meghan (University of Delaware, 2009)

Background – Over the past three decades there has been considerable and conflicting debate on the impact of iron mediated oxidative damage on coronary heart disease. Objective - To determine if the baseline participants ...
A case study: The impact of the 1962 northeaster on Delaware’s Atlantic coastline

McCarty, Elizabeth (University of Delaware, 2009)

The 1962 Northeaster, called by many “The Storm of the Century,” was one of Delaware‟s most devastating coastal storms. It lasted over more than five consecutive, semi-diurnal, perigean spring tidal cycles (Zhang et al., ...
Use of a novel magnetic resonance imaging based modeling technique to investigate differences in tibiofemoral articular cartilage contact area In subjects with moderate knee osteoarthritis

Henderson, Christopher (University of Delaware, 2009)

Knee osteoarthritis (OA) detrimentally impacts the lives of millions of older Americans through pain and decreased functional ability. Unfortunately, the pathomechanics and associated changes that OA patients experience ...
Model catalysts for high-pressure spectroscopic investigations

Bedenbaugh, John (University of Delaware, 2009)

In molecular-level catalytic investigations, discrepancies that exist between surface science observations under ultra-high vacuum (UHV) conditions and industrial catalytic performance at higher pressures are referred to ...
Binary dithered oversampling analog-to-digital converters

Pienovi, Diego (University of Delaware, 2009)

In today’s world, analog-to-digital converters (ADC) play a major role. Our modern society requires and depends on electronic devices that process the analog input data in the digital domain, such as cellphones, audio ...
