A Cluster Of Trace-Concentration Methamphetamine Identifications In Racehorses Associated With A Methamphetamine-Contaminated Horse Trailer: A Report And Analysis, Kimberly Brewer, Theodore F. Shults, Jacob Machin, Sucheta Kudrimoti, Rodney L. Eisenberg, Petra Hartman, Caroline Wang, Clara Fenger, Pierre Beaumier, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Three low concentration methamphetamine “positive” tests were linked to use of a methamphetamine-contaminated trailer to transport the affected horses. This incident establishes methamphetamine as a human-use substance that can inadvertently enter the environment of racing horses, resulting in urinary methamphetamine “positives;” an interim regulatory cut-off of 15 ng/mL for methamphetamine in post-race urine is proposed.

This work was conducted under permit #3384 from the State Archaeologist’s office at the Massachusetts Historical Commission. The 2015 work focused on the eastern edge of Burial Hill along School Street in downtown Plymouth where …

Enzymatic Liquefaction Of Untreated Corn Stover, Neal N. Hengge

Open Access Theses

There is an ever increasing need for renewable alternatives to fossil fuels derived from petroleum. This makes feedstocks in the form of lignocellulosic biomass attractive substrates for the production of ethanol and value added chemicals. However, the economics of converting lignocellulosic materials involve high processing costs attributed with pretreatment of the biomass and the use of enzymes for saccharification. Corn stover was obtained for the examination of an upstream processing step to transform the material into a pumpable slurry for subsequent pretreatment and saccharification. Biomass liquefaction was carried out using the enzyme Depol 692L (Biocatalysts, Wales, UK) at 50°C with …

An Assessment Of The Competitive Ability Of Oak Species In The Central Hardwood Region Using Both Pre-Harvest Treatment Data And Stem Analysis Techniques, Robert William Edward Quackenbush

Open Access Theses

The density of advance regeneration of oak species has been in decline across the Central Hardwood Region (CHR) for the past 50 years. This phenomenon has been accredited to many different factors, ranging from predation and browse by wildlife, to human induced changes in the environment which include massive clearcutting, land use change from forest to agriculture, and suppression of fires which played an intricate role in the development of oak systems across the CHR. The objectives of this research project were to compare densities of oak advance regeneration across two different environmental gradients within the CHR, in particular the …

Superheroes And Social Action: Reproduction, Recurrence, And Recognition In The Superhero Genre, Max M. Renner

Open Access Theses

Rhetorical genre analysis examines genre as social action and is primarily concerned with the experiences of individual users (Miller, 1984). The genres that rhetorical genre scholarship takes up are typically functional genres or genres in which individuals have direct means of utilizing and modifying a genre. This focus on functional genres makes sense in terms of the tradition’s interest in user experience and reciprocity. This project seeks to examine the potential implications rhetorical genre analysis has for vernacular genres which, for the most part, have remained the domain of literary scholarship due to their focus on structural, formal elements.

The Interactive Effects Of Pesticide Exposure And Infectious Disease On Amphibian Hosts, Katherine M. Pochini

Open Access Theses

Natural systems are home to a multitude of natural and anthropogenic stressors, which draw an array of effects on ecological communities. While these effects have been investigated individually, it is important, given the routine co-occurrence of these stressors, to understand their interactive effects. Pesticide exposure and infectious disease are two common, co-occurring stressors that each have documented detrimental effects on species and, as evidence suggests, may have interactive effects. Moreover, existing research suggests that these interactive effects are highly context dependent, eliciting different results based on species, disease agent, toxin, and environment. Given the variability with which species may experience …

High School Students' Motivations And Views Of Agriculture And Agricultural Careers Upon Completion Of A Pre-College Program, Andrea K. Scherer

Open Access Theses

Pre-college summer residential experiences hosted by a College of Agriculture have the potential to expose high school students to new career opportunities and fields of study that they may not have considered, and may influence agricultural literacy, perceptions of agriculture, and interest in agriculture. Engaging these students is important for meeting the demand for more students graduating with agriculture degrees prepared to solve 21st century challenges. The purpose of this study was to explore and describe the outcomes of two separate pre-college experiences, the Molecular Agriculture Summer Institute (MASI) and the Purdue Agribusiness Science Academy (PASA), and participating high school …

Visual Detail And Its Effects On Character Attachment In Video Games, Carl Sommer

Open Access Theses

The video game industry has been experiencing a trend toward independent game developers making their own games, as well as large companies opening smaller divisions to work on smaller games. This can be looked at from a purely financial perspective, given that smaller games will inevitably consume a smaller budget; however, there is also good reason to believe there can be substantial creative benefits to companies indulging in this trend. This research is concerned with the effect that visual detail can have on a players emotional attachment to characters in video games-otherwise known as character attachment. While intuition may often …

Mapping And Analyzing Energy Use And Efficiency In A Modified Hydroponic Shipping Container, Rachel E. Sparks

Open Access Theses

In urban centers today, vertical farming is becoming a popular alternative to conventional agriculture in an effort to increase local food production and improve urban food security by growing crops using hydroponic methods in controlled environment spaces. More specifically, one vertical method involves growing crops inside refurbished shipping containers, or a “farm-in-a-box” concept, which offers a flexible, mobile, and scalable means of year-round food production in a variety of climates. Despite benefits of producing food locally, some of the concerns associated with these vertical farming systems include high energy consumption from climate control and electric lighting systems as well as …

Metal-Promoted Self-Assembly Of Collagen Mimetic Peptides Into Biofunctional Scaffolds For Stem Cell Delivery With The Aim Of Tissue Regeneration, Kevin Strauss

Open Access Theses

Collagen is a strong, sturdy, but malleable, protein found abundantly in the extracellular matrix. Consequently, it has become an invaluable biomaterial for use in regenerative medicine. However, natural collagen poses difficulties when it comes to customization and structural control, as well as the risk of infectious prions from animal sources. Our approach utilizes shorter, synthetic collagen mimetic peptide sequences. These peptides retain the incredible triple helical stability of natural collagen but can be modified with versatile metal-binding ligands. In the presence of an appropriate metal ion, the peptides self-assemble into diverse, three-dimensional morphologies. The peptide NCoH, functionalized with N-terminal NTA …

Nutrient Runoff And Leachate After Land-Application Of Digestate In A Laboratory Study Using Rainfall Simulations, Min Xiao

Open Access Theses

There has been an increasing number of anaerobic digesters on livestock farms in the United States during the past two decades. Anaerobic digestion of manure allows production of renewable energy and generation of stabilized and nutrient-rich digestate that can be used as organic fertilizer. However, the majority of the existed studies using liquid digestate as fertilizer only focused on the effectiveness for crop yield, nutrient content and microorganism in soil. There is insufficient understanding in the environmental impact of digestate land-application. This laboratory study used six treatments including four different liquid digestate treatments, a chemical fertilizer treatment, and an unfertilized …

A Platform For Otakus To Gradually Learn And Adapt To Social Conventions, Shang Xu

Open Access Theses

It is believed that good design should not only satisfy users’ needs, but also improve their overall quality of life. Nowadays, with the rapidly increasing amounts of time spent on the internet, more and more people, the majority of them youngsters, claim themselves as otakus since they cut themselves off from face-to-face communication. From my primary and secondary user studies, most otakus have difficulties interacting with strangers in real world contexts, but some do want to expand their social networks. This design hypothesis is to provide opportunities for otakus to meet people and build friendships in real life. The purpose …

A Dose Distribution Study Of Uranyl Nitrate In Zebrafish Using Liquid Scintillation And Passivated Implanted Planar Silicon Detectors, Lee A. Alleman

Open Access Theses

Standard curves for a Perkin Elmer TriCarb 2800 liquid scintillation detector (LSC) and a Ludlum 3030p Passivated Implanted Planar Silicon detector have been developed and utilized for studying the dose distribution of depleted uranium (DU) within zebrafish. The DU source was crystallized uranyl nitrate (N2O8U•6H2O) solution, normally used for staining in electron microscopy with a manufactured average specific activity of 0.3 uCi/g. Zebrafish, both larvae and adults, were exposed to three different mass concentrations, dissected, dissolved and counted using an LSC. The counts were compared to the standard curve correlating the measured activity to that of the mass absorbed. It …

Farmers' Use Of Mobile Phone Technology For Agricultural Information Services In Lilongwe District, Malawi, Benjamin F. Chisama

Open Access Theses

Mobile phone technology can be a useful tool to provide farmers with relevant and reliable agricultural information for critical farming decisions in developing countries such as Malawi. An increasing number of rural farmers have been faced with information asymmetry challenges due to some pitfalls in the extension systems. In addition, knowledge gaps on farmers’ use of mobile phone technology; their awareness and use of MAIS; and their preferred topics to be delivered using mobile platforms were identified. However, little was known on how farmers were using existing MAIS. This study’s aim was to explore the potential of providing mobile agricultural …

My thesis so far has been to develop software that will help POD sites better be able to train their volunteers in the case of an emergency. We have already collected some data for our research from a test POD site that was constructed. We took data on the amount of time it took each volunteer to get an individual actor through the line depending on whether they learned via teacher …

Economic Viability Of Flexible Biogas Pumps In Bangladesh, Saima A. Matin

Open Access Theses

This study examines the economic viability of flexible irrigation pumps that can run on biogas as well as diesel fuel in Bangladesh. Such examination faces two main hurdles. First, the ease with which farmers running flexible pumps can switch from one energy source to another is unknown and perhaps highly heterogeneous. Second, diesel prices in Bangladesh are volatile and limited information precludes direct estimation of their probability distribution. We address the first issue by evaluating the economics of flexible pumps for varying degrees of inter-fuel substitutability. To deal with the second issue, we model the probability distribution of Bangladeshi diesel …

Metabolomics Approach To Investigate Oxidation Stabilities In Different Bovine Muscles With Postmortem Aging, Danyi Ma

Open Access Theses

Postmortem aging has been extensively practiced in the meat industry for decades due to its beneficial impact on improving eating quality attributes. However, prolonged postmortem aging may adversely impact color and/or lipid oxidation stabilities of meat, leading to decreased display shelf-life and increased rancid off-flavor. As physical/biochemical changes occur during postmortem aging, metabolites that impart antioxidant or pro-oxidant activities are generated or consumed, which could be related to the oxidation stabilities of postmortem muscles with aging. However, the underlying mechanism of the aging-induced oxidation susceptibility has not been fully established. Therefore, the overall objective of this thesis was to understand …

Analysis Of Structural And Functional Brain Networks, Jun Young Jeong

Open Access Theses

The brain is a representative example of a network. It consists of numerous spatially distributed regions that continuously exchange information through structural connections. In the past decade, an increasing number of studies have explored the brain network in both structural and functional aspects; they have begun to decipher complex brain wirings, as well as elucidate how the rich functionality emerges from this architecture. Based upon previous studies, this thesis addresses three critical gaps in the field. (I) Although it is known that the community structures of brain network are spatially overlapping, conventional studies have focused on grouping brain regions into …

Despite high levels of public concern, the state of commercial breeding (CB) dog welfare is largely unknown. Therefore, this study aimed to characterize the physical welfare of dogs in CB facilities and their environment in Indiana. This study specifically aimed 1) to characterize dog foot health in CB facilities as a function of the length of time dogs were housed on a given flooring substrate, 2) to characterize visual dog body cleanliness and visual kennel cleanliness as a function of the flooring substrate, 3) to determine the efficacy of kennel cleaning procedures and 4) to characterize the dog dental and …

Post-Transition Human Rights Performance In Peru, Uruguay, And South Korea, Nusta Pitushca Carranza Ko

Open Access Dissertations

The literature on transitional justice and international human rights norms has been useful for explaining norm internalization for transitioning states. And yet, the literature could not account for the variations to state behavior after norms were implemented via domestic transitional justice policies of truth-seeking, prosecutions, and reparations. Why have states where great efforts were put into confronting an ugly past relapsed in their behavior? This research fills this lacuna be examining the period after states institute transitional justice policies to determine how states have varied in respecting norms. Taking the case of Peru, Uruguay, and South Korea that have advanced …

Influence Of Dietary Component Manipulation And Feed Management Strategies On Growth And Rumen Development Of Weaned Dairy Heifers, Tana Shea Dennis

Open Access Dissertations

Well-developed replacement heifers provide a central foundation for the continued success of the dairy industry. Emphasis on improving pre-weaned calf nutrition has predominated in the industry, but opportunities exist to improve post-weaning heifer nutrition and management. We aimed to evaluate common feed management strategies seen in the industry and their effects on growth, feed efficiency (G:F), and rumen development of calves from birth to 8 mo of age using pen- and individually-fed animal trials. Little information exists regarding post-weaning performance and rumen development of calves fed conventional or high planes of nutrition pre-weaning; therefore, we evaluated two milk replacer feeding …

Knowledge Modeling Of Phishing Emails, Courtney Falk

Open Access Dissertations

This dissertation investigates whether or not malicious phishing emails are detected better when a meaningful representation of the email bodies is available. The natural language processing theory of Ontological Semantics Technology is used for its ability to model the knowledge representation present in the email messages. Known good and phishing emails were analyzed and their meaning representations fed into machine learning binary classifiers. Unigram language models of the same emails were used as a baseline for comparing the performance of the meaningful data. The end results show how a binary classifier trained on meaningful data is better at detecting phishing …

The Effects Of Including Almonds In An Energy-Restricted Diet On Weight, Body Composition, Visceral Adipose Tissue, Blood Pressure And Cognitive Function, Jaapna Dhillon

Open Access Dissertations

Inclusion of almonds in an energy restricted diet has been reported to enhance or have no effect on weight loss. Their effects specifically on visceral fat stores during energy restriction have not been widely examined. Additionally, almond consumption has been associated with reduced blood pressure, but whether this is linked to or is independent of changes of body composition has not been examined. Moreover, almond consumption during energy restriction may be an effective strategy for reversing the negative effects of dieting on cognitive performance. The unique nutrient profile of almonds also has the potential to influence cognitive function post-prandially. The …

The Politics Of Town Hall Meetings: Analyzing Constituent Relations-In-Interaction, Robert J. Green

Open Access Dissertations

The politics of town meetings proposes that town hall meetings are institutions of representative democracy that present an opportunity for constituents to hold their elected representatives accountable in a public setting. Constituent relations-in-interaction glosses a complex set of interactional practices and procedures through which ensembles of participants bring town hall meetings, as structures of social interaction, into being. This study uses conversation analysis, the study of talk-in-interaction, to show that the politics of town hall meetings orients to three types of accountability: Interactional accountability, political accountability, and public accountability. The articulation of these accountability types provides a sense of overall-structural …

Biochemical Changes In Animal Models Of Fetal Alcohol Spectrum Disorder, Christine E. M. Keller

Open Access Dissertations

Fetal alcohol spectrum disorder (FASD) is a completely preventable disease, that has profound effects on life-long health and function of the affected individual. Prevalence estimates of FASD in the United States indicate 33.5 per 1,000 live births are affected with this disorder (Roozen, 2016). FASD is caused by maternal ethanol intake during pregnancy. However, recommendations of the amounts of alcohol safe to drink during pregnancy are not established. Further, we lack a comprehensive understanding of the biochemical pathways modified in prenatal ethanol exposure. Biomarkers are also lacking. Our results demonstrate the vast array of biochemical pathways modified in the chronic …
