Using Stable Isotopes To Quantify Nitrogen Fates In Container Plants, Sam Raimann, Greg Michalski, Michael V. Mickelbart

The Summer Undergraduate Research Fellowship (SURF) Symposium

Currently, in the agriculture field, it is not yet known the accurate amount of Nitrogen in fertilizer that plants take up. This statistic, known as the Nitrogen Use Efficiency is currently known to be within the 30-50% range (Lea-Cox and Ross, 2001). This is very important figure to know and it is a figure that can be improved, and therefore much time, energy, and resources can be saved. This research project will use concepts involving stable isotopes to examine red maple plant material and the soilless media that the plants were grown in. Three different isotope-labelled fertilizer treatments will be …

Surgical Adhesive From Mussel Mimetic Polymer, Jenna Desousa, Cori Jenkins, Jonathan Wilker

The Summer Undergraduate Research Fellowship (SURF) Symposium

Injuries involving damaged tissues are currently repaired through an invasive technique involving the use of screws, plates and sutures as support, which can damage these tissues. The biomedical field currently lacks an adhesive that can replace harmful implants. A surgical adhesive can provide a quick and easy alternative, which will minimize the risk of damaging healthy tissue in surgery. Inspiration for such materials can be found by looking at marine mussels as they are able to stick to nearly any surface, even in wet environments. Marine mussels affix themselves to different surfaces using adhesive plaques consisting of various proteins. Polymer …

Evaluating Contaminants Of Emerging Concern In Commercial Biosolid-Based Fertilizers, John Hemmerling, Michael L. Mashtare, Linda S. Lee

The Summer Undergraduate Research Fellowship (SURF) Symposium

The production and popularity of commercially available biosolid-based fertilizers are increasing because of their economic, environmental, and plant nutrition benefits, particularly in urban and suburban areas. Because biosolid-based fertilizers are derived from waste water treatment plant residuals, we hypothesized that there is the potential for micropollutants to persist in these products. Their presence would be of particular concern due to their potential impact on human and ecological health and risk of bioaccumulation. This study involves quantifying contaminants of emerging concern in three biosolid-based fertilizers, and 2 non-biosolid-based fertilizers, a composted animal manure and an organic compost. Our extraction method employed …

Determination Of Anions In Lanana Creek By Ion Chromatography, Tania Benavides

Undergraduate Research Conference

Abstract

Lanana Creek is one of two springs that surround Nacogdoches, TX. Lanana Creek starts southwest of Lake Naconiche, conjoining with several other bodies of water along its path, and becomes part of the Angelina River. This body of water eventually ends in the Gulf of Mexico which may contribute to the dead zone. Contaminants in water may be of small concentration; however, prolonged exposure could produce many negative effects. To prevent further contamination, the source of the contamination must be identified through testing the water for contaminants. Some possible sources of contamination may be from fertilizers and pesticides used …

Ice Caves On Extraterrestrial Bodies: What Are The Prospects For Speleogenesis And Detection?, Penelope J. Boston

The International Workshop on Ice Caves

Potential mechanisms for creating cavities in icy extraterrestrial bodies have been tentatively explored by several authors. On one hand we have examples of mechanisms that create caves in water ice here on Earth. In addition, there may be unique mechanisms on other Solar System objects that do not occur on Earth but might produce cavities, e.g. sublimation of comets upon perihelion passage. The methods of detecting such cavities depend upon the nature of the icy body in question, the potential for orbital or landed missions to visit those bodies in the future, and remote or landed methods for detecting the …

Assessing Water Treatment Residuals As A Filtration Media For Phosphorus Removal At Wapato Lake - Tacoma, Wa, Brian Hite, Megan Hintz

Salish Sea Ecosystem Conference

Wapato Lake in Tacoma, WA is a 23-acre urban lake that has had problems of eutrophication and toxic algae blooms for over a hundred years. Inputs of phosphorus from both environmental and anthropogenic sources contribute to this problem. Much of the 900-acre watershed consists of residential or commercial development, increasing the amount of stormwater containing increased levels of phosphorus. Past management efforts designed to control eutrophication at Wapato included constructing a diversion structure to route phosphorus rich stormwater around the lake. This plan increased the retention time of Wapato to ≈ 8.5 years. We have been tasked by the City …

Quantification Of Pharmaceuticals, Personal Care Products, And Perfluoroalkyl Substances In Elliott Bay Sediments (Seattle, Washington), Margaret Dutch, Sandra Weakland, Valerie Partridge

Salish Sea Ecosystem Conference

Pharmaceuticals and Personal Care Products (PPCPs) and Perfluoroalkyl Substances (PFASs) are identified as Chemicals of Emerging Concern (CECs) in Puget Sound due to their potential to cause adverse toxicological, biological, and ecological effects when introduced into the environment. Characterization of sources, transport patterns, and the fate of CECs in the environment has been prioritized as part of the Puget Sound Ecosystem Monitoring Program toxics monitoring strategy. These chemicals have been detected in ground water, rivers, and streams in the Pacific Northwest and in influent, effluent, and biosolids from Puget Sound municipal wastewater treatment plants over the past decade. They were …

A Molecular Framework To Identify Novel Modes Of Action Of Endocrine Disrupting Compounds In Shellfish, Mackenzie Gavery, Steven (Steven Beyer) Roberts

Salish Sea Ecosystem Conference

Concern over human and wildlife health has brought increased attention to a group of emerging environmental contaminants referred to as endocrine disrupting compounds (EDCs). While progress has been made in describing the effects of these compounds, there are still gaps in our understanding of alternative modes of action and physiological effects outside of the reproductive axis, particularly in invertebrates. One way that EDCs may elicit these changes is through disruptions to normal epigenetic mechanisms. Epigenetics refers to heritable processes that alter gene activity without manipulating the underlying DNA sequence. Epigenetic marks, such as DNA methylation, are important regulators of gene …

Molecular Modeling Of Biological Carbon Fixation, William Lin, Andrew Kim, Scott Hansen

CLAS: Colby Liberal Arts Symposium

Biological carbon fixation is primarily catalyzed by one enzyme: ribulose-1,5-bisphosphate carboxylase oxygenase. We use molecular modeling to explore and elucidate the origin of slow kinetics and poor specificity in this enzyme. We present primary results of correlated motion between the enzyme and the active site.

The Development And Characterization Of Dual Electrodes For Use With Scanning Electrochemical Microscopy, Colleen Leonard, Melinda Baur, Faculty Advisor

John Wesley Powell Student Research Conference

Scanning Electrochemical Microscopy (SECM) utilizes electrode probes that can be positioned just abutting cells and can detect the presence of small quantities of chemicals known as neurotransmitters. In order to detect neurotransmitter release from PC12 cells, used as model neurons, the electrode must be positioned very close to the cell surface to detect the change in current that accompanies the oxidation/reduction of the neurotransmitters released. The peaks in current were analyzed in order to detect differences in release mechanisms, such as slow or fast-release. Furthermore, dual electrodes were made and characterized in order to monitor two different locations on a …

Isolation Of Antibacterial Compounds From Artemisia Californica, Jae Eun Min

Seaver College Research And Scholarly Achievement Symposium

The Chumash Native Americans of Southern California have well-documented traditions of using plants for medicinal purposes. If a specific plant has traditionally been used by Chumash for the treatment of cuts, wounds and infections, it may contain chemicals with anti-bacterial properties. One plant that fits these criteria is Artemisia californica (coastal sage). Because of the widespread use of antibiotics over the past sixty years bacteria are evolving greater resistance to known antibiotics, but unfortunately the rate of antibiotic discovery has diminished during the past twenty years. Therefore, novel and effective antibiotics are essential for the continued treatment of bacterial infections. …
