Integration of embryonic zebrafish and passive sampling device extracts to explore effects of pesticide mixtures

Creator:: Corvi, Margaret
Abstract:: Pesticides are ubiquitous, with more than one billion tons of pesticide products used in the United States annually. These compounds are characterized by their toxic effects to the target organism; however, pesticides are also well known for their deleterious effects to non-target species. Because pesticides have ecological and human health...

Development of a colorimetric test kit to determine enzymatically produced pyruvic acid in sweet onions

Creator:: Merrill, Dawn C.
Abstract:: Sweet onions are valued for their unique flavor and praised for their health and dietary character. Onion sweetness is perceived as the degree of pungency decreases. Pungency can be quantitatively determined in onions by measuring enzymatically produced pyruvic acid. The onion industry quantifies a sweet onion as one having a...

The Release of Nickel from Stainless Steel into Cooked Foods

Creator:: Kamerud, Kristin L.
Abstract:: Toxicological studies show that oral doses of nickel can cause allergic contact dermatitis, and routes of exposure, such as nickel leached from stainless steel cookware are not well characterized. In this study, four variables: grade of stainless steel, cook time, stainless steel seasoning or cooking cycles, and commercial tomato sauces,...

Trace element concentration in tree-rings biomonitoring centuries of environmental change

Creator:: Padilla, Kimberly L. and Anderson, Kim A.
Abstract:: Inductively coupled plasma mass spectrometry (ICP-MS) was used to examine trace element concentration in treerings over three and half centuries to assess macro-trends of environmental change. Tree-rings of a 350+ year old mammoth ponderosa pine (Pinus ponderosa) were analyzed for element concentration and evaluated versus local and global historical events....

Analysis of Organochlorine Pesticides (OCPs) in Gray Whale Scat as an Alternative Method of Toxicant Quantification in Cetaceans

Creator:: Kutnerian, Amy M.
Abstract:: A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...

Identification of Pseudomonas syringae genes required for perception of host-derived virulence-inducing metabolites

Creator:: Turner, Sydney E.
Abstract:: Pseudomonas syringae is a Gram-negative bacterium that can infect a variety of important crops. Infection by P. syringae is dependent on a type III secretion system (T3SS) that delivers effector proteins to plant cells to suppress host defenses. Previous work has shown that, in the presence of simple sugars, specific...

Regulation of the Pantoea agglomerans type III secretion system by plant-exuded sugars

Creator:: Bacher, Daniel
Abstract:: Pantoea agglomerans pathovar betae (Pab) is a bacterium that causes galls on the roots of beet plants, resulting in reduced marketability of beet roots and crop loss. Pab uses a type III secretion system (T3SS) to infect and cause galls on beets. The T3SS is a molecular syringe-like structure that...

The Deviance of Deviant Research: An Analysis of The Extensibility of Social Construction and Research Surrounding Deviance

Creator:: Anderson, Kaylyn H.
Abstract:: The preceding empirical research examines the traditional and evolutionary research surrounding youth deviance. Deviance is routinely discussed as an adverse impact in a plethora of theories and it is imperative to further develop the knowledge of deviance as society progresses. In this report, the utilized sample group approximately (n=13583) was...

Wintertime grazing rates of Antarctic krill, Euphausia superba, along the Northern Antarctic Peninsula

Creator:: Gunther, Lacey, Bernard, Kim, Reiss, Christian, and Dietrich, Kim
Abstract:: Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...

An analysis of control area synchronization on the convergence of distributed state estimators

Creator:: Clarke, Blaise
Abstract:: This honors undergraduate thesis examines the process of simulating power system state estimation, the use of the alternating direction method of multipliers in the problem of distributed power system state estimation, and provides a rudimentary asynchronous implementation of the above for a linearized DC power system. The asynchronous implementation is...
