Identification, Quantification, and Risk Assessment of Polycyclic Aromatic Hydrocarbons and their Derivatives in Soil after Steam Enhanced Extraction

Creator:: Santiago Delgado, Lisandra
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are environmental contaminants produced mainly from the incomplete combustion and pyrolysis of organic matter. PAHs are among the major contaminants at over 800 Superfund sites, nationwide. Thermal remediation is used as a method to remediate soils contaminated with PAHs through the use of heat to mobilize...

Collaborative assessment and management of transboundary aquifers in North America

Creator:: Alvarez Tostado Delgado, Pablo
Abstract:: The Law of Transboundary Aquifers, introduced to the United Nations General Assembly in December 2008, encourages nations to make multilateral arrangements for the proper management of transboundary aquifers. This study seeks to answer the question: “What are the main challenges for successful collaboration in assessing and managing Transboundary Aquifer Systems...

Development of High-Throughput Screening Methods to Determine Efficacy of “Clean-Label” Antifungals for Application on Cheese

Creator:: Jensen, Kristen
Abstract:: Cheese has been produced since ancient times and continues to be an important nutrient-dense staple in many diets around the world. Cheese quality is of high importance to consumers, and it is important for cheese producers to establish process controls to prevent and control cheese spoilage. Fungal spoilage is of...

Contribution of Farm Level Milk Sourcing on Non-Starter Lactic Acid Bacteria (NSLAB) in Cheddar, and the Assessment of High Resolution Melt Analysis used for Species Identification

Creator:: Baird, Christopher S.
Abstract:: Non-starter lactic acid bacteria (NSLAB) are found at low levels in fresh raw milk and are important to the dairy industry because of their potential impact on the flavor and texture of yogurt, sour cream, and cheese. The purpose of this study was to evaluate three methods for the identification...

Impact of weak and strong acids on the destruction of lactic acid bacteria during high pressure processing

Creator:: Sarangapani, Rama Krishna
Abstract:: High hydrostatic pressure (HHP) affects the pH of weak acids due to an increased degree of acid dissociation while under pressure. The temporary pH reduction by high pressure in such a case may influence the barotolerance of microorganisms. The objective of this study was to determine the impact of weak...

Development and disease of opakapaka (Pristiopomoides filamentosus) larvae in culture

Creator:: Keafer, Briana
Abstract:: Opakapaka (Pristipomoides filamentosus) is a snapper (family Lutjanidae) native to the waters around Hawaii. Recent population declines of this commercially important species have increased interest in the culture of this fish. Survival of this fish through the larval period in culture has been consistently low, usually not exceeding 2%. The...

Reburn Severity and Vegetation Recovery in Southwestern Oregon, USA

Creator:: Weber, Rebecca N.
Abstract:: The Klamath-Siskiyou Ecoregion of southwest Oregon and northern California is greatly departed from its historic, mixed-severity fire regime. This departure manifests in larger wildfires, greater proportions of high burn severity within wildfire perimeters, and decreased diversity of post-fire vegetation successional stages and trajectories across the landscape compared to historical norms....

The preparation of common prebiotic oligosaccharides with defined degree of polymerization

Creator:: Ooi, Megan C. Y.
Abstract:: Prebiotics are a subset of dietary fiber that is growing in demand within the food industry. The health benefits of prebiotics have been well established, leading to the increase in its incorporation into various food products. Given the importance of prebiotics as functional ingredients, it is important to understand their...

The Influence of Stormwater Water Quality on the Adsorption of Copper and Zinc onto Five Different Sorbents

Creator:: Kanalos, Casey A.
Abstract:: Best Management Practices (BMP) are widely used as a method for stormwater volume control in urban areas to prevent an overload of water on receiving water bodies and treatment facilities. BMPs ability to treat stormwater has gone under critical review in the last few decades, and their performance varies both...

Using Satellite Imagery to Count Nesting Albatross from Space

Creator:: Dolliver, Jane E.
Abstract:: One fundamental concern in conservation biology is species abundance. For many taxa, however, these data are costly to obtain via direct observation and thus limited in geographic or temporal scope. Very high-resolution satellite imagery provides a means to address these limitations and provide remotely-sensed counts of large, colonial species. We...

An economic and socio-cultural analysis of new farm technology : the case of stabling in Senegal

Creator:: Fisher, Monica Grace
Abstract:: A study is conducted to provide information useful to the future development of agro-pastoralists in the Kolda Region through an economic and socio-cultural analysis of the practice of stabling. Two main issues are addressed: the generation and distribution of profits and the factors related to adoption of stabling. A partial...

Large Scale Tensor Decomposition Algorithms Using Block-randomized Stochastic Proximal Gradient

Creator:: Gao, Cheng
Abstract:: We consider the problem of computing the cannonical polyadic decomposition (CPD) for large-scale dense tensors. This work is a combination of alternating least squares and fiber sampling. Data sparsity can be leveraged to handle large tensor CPD, but this route is not feasible for dense data. Inspired by stochastic optimization's...

Adding context and value to online security ratings by combining heuristics with community based ratings

Creator:: Ayyavu, Prashanth
Abstract:: The Internet is growing rapidly in terms of websites, users and uses. People use the Internet for reference, shopping, social networking, communications, business and much more. Though the Internet is useful, there are many risks associated with its use, like malicious websites, identity theft, hateful content and fraudulent practices. Online...

Juvenile Pacific Oyster Growth and Food Resources in Eelgrass Habitats of Variable Shoot Density in Tillamook Bay, OR: Ecosystem Interactions for Management Consideration

Creator:: Merrill, Julianne
Abstract:: As the global demand for seafood increases each year, there is a growing need to expand sustainable aquaculture in the interests of food security and resilience of coastal communities. Pacific oysters, Crassostrea gigas, are grown in West coast estuaries - where cultures often overlap with the federally protected native eelgrass,...

Pillaging Bloodwood: An Exploratory Examination of Illegal Deforestation in Guinea-Bissau Through Forest Disturbance Algorithms and Unsupervised Clustering Techniques

Creator:: Walters, Alexander E.
Abstract:: Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...
