Open-Source Tig-Based Metal 3d-Printing, Shane Oberloier

Dissertations, Master's Theses and Master's Reports

Metal 3-D printing has been relegated to high-cost proprietary high-resolution systems and low-resolution low-cost metal inert gas (MIG) systems. In order to provide a path to high-resolution, low-cost, metal 3-D printing, this manuscript proposes a new open source metal 3-D printer design based around a low-cost tungsten inert gas (TIG) welder coupled to a commercial open source self replicating rapid prototyper. Optimal printing parameters for the machine are acquired using a novel computational intelligence software. TIG has many advantages over MIG, such as having a low heat input, clean beads, and the potential for both high-resolution prints as well as …

Effects Of Methyl Jasmonate On Quality Properties And Phytochemical Compounds Of Kiwifruit (Actinidia Deliciosa Cv. `Hayward') During Cold Storage And Shelf Life, Burhan Öztürk, Furkan Yücedağ

Turkish Journal of Agriculture and Forestry

The research aimed to assess the effects of methyl jasmonate (0.25, 0.5, and 1.0 mM MeJA) on weight loss and phytochemical compounds of kiwifruit (Actinidia deliciosa cv. `Hayward') throughout the cold storage and shelf life. Kiwifruits were stored at 0 ± 0.5 °C and 90 ± 5% RH for 180 days, and at 20 ± 1.0 °C and 80 ± 5% RH for 5 days in shelf life conditions. During cold storage, weight loss was significantly lower (P < 0.05) in 0.25 and 1.0 mM MeJA treatments than those of control and 0.5 mM MeJA treatments. The highest flesh firmness was determined in MeJA-treated fruits. In the latest measurement period of cold storage and shelf life, the lowest respiration rate was obtained from 0.5 and 1.0 mM MeJA treatments. MeJA-treated fruits had significantly higher hue angle at the end of cold storage. Generally, in shelf life analysis, acidity of MeJA-treated fruits was significantly lower than that of control fruits. At the end of cold storage, the highest vitamin C, total flavonoids, and antioxidant activity (DPPH) were measured in 1.0 mM MeJA treatment, whereas the highest total phenolics were detected in 0.25 mM MeJA treatment. Present findings revealed that MeJA could be used as an effective postharvest tool to maintain flesh firmness and phytochemical compounds of kiwifruits.

Impact Of Roasting Level On Fatty Acid Composition, Oil And Polycyclic Aromatic Hydrocarbon Contents Of Various Dried Nuts, Emel Öz, Eli̇f Eki̇z, Adem Savaş, Eyad Aoudeh, A.M. Abd El-Aty, Fati̇h Öz

Turkish Journal of Agriculture and Forestry

Herein, the effects of roasting levels (rare, medium, and well) on the fatty acid composition, oil and polycyclic aromatic hydrocarbon (PAH) contents of various dried nuts (almonds, hazelnuts, peanuts, and cashews) were investigated. The roasting level affected the moisture and total oil contents, as well as the fatty acid composition. The roasting level had no significant effect (P > 0.05) on saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) contents of the dried nuts, while it had a significant effect (P < 0.05) on polyunsaturated fatty acid (PUFA). In raw and dry roasted nut, the most common SFA, MUFA, and PUFA were palmitic, oleic, and linoleic acid, respectively. The amounts of linoleic acid and ΣPUFA, as well as ΣPUFA/ΣSFA ratio were the lowest in the well roasted samples. Additionally, the types of dried nut had a significant effect (P < 0.01) on the amounts of total oil and fatty acid compositions. The highest total oil amount (62.15%) was found in hazelnuts, while the lowest PUFA content (7.54%) was also determined in hazelnuts. From the nutritional perspective of view, the highest ΣPUFA / ΣSFA ratio (2.40) belonged to almonds. Although the recovery rates of PAH standards varied between 70.14%-85.10%, none of the heavy PAH compounds could be detected in raw and roasted samples.

The data provides insight into what pre-service …

A Review Of The Molecular Mediators Of Host-Baculovirus Interactions In Lepidoptera, Olivia Crouse

Honors Program Theses

Iowa farmlands occupy approximately 85% of its 35.7 million acres, and Iowa leads the United States in corn and soybean production, with an estimated 2.58 billion and 502 million bushels of corn and soybean produced in 2019, respectively. This successful trend in annual yields has span forty plus years and been consequential to the simultaneous implementation of agricultural- and science-based practices. Genetically modified corn and soybean crop varieties express genes from Bacillus thuringiensis (Bt) which encode insecticidal proteins that protect, with high specificity, against insect pests. While researchers continue to study the molecular mechanism(s) of Bt extensively, alternative environmentally safe …

Faculty Articles, Papers, and Other Scholarship

Students, particularly those in STEM and healthcare-related programs, should develop proficient interpersonal skills, including communication. To help students develop effective communication skills, instructors need to consider the value students give to learning these skills. The Student Attitudes Toward Communication Skills Survey (SATCSS) was developed to measure how undergraduate students value learning communication skills based on Expectancy-Value Theory across three modes of communication (verbal, written, non-verbal). The survey was given to students interested in healthcare professions and enrolled in an undergraduate anatomy and physiology course (n = 233) at a Midwest research active university. The survey showed evidence of validity, measuring …

Diet And Nutrition Of Adult Spalangia Cameroni (Hymenoptera: Pteromalidae), A Parasitoid Of Filth Flies, Elizabeth H. Taylor, Bethia H. King, Edwin R. Burgess Iv

Faculty Articles, Papers, and Other Scholarship

Most parasitoid wasps parasitize herbivorous insects, so nectar from flowers is readily available. However, parasitoid wasps are also an important component of the rich invertebrate communities at livestock facilities in large accumulations of manure, where flowers are largely absent. Little is known about adult parasitoid diet and nutrition in these communities. The present study examined this in Spalangia cameroni, a pupal parasitoid of filth flies. Like many parasitoid wasps, S. cameroni feed on host fluids, and in the laboratory readily feed on honey or a sucrose solution, which increases their longevity. Here adult longevity in the presence of six potential …

Concomitant Accumulations Of Ions, Osmoprotectants And Antioxidant System-Relatedsubstances Provide Salt Tolerance Capability To Succulent Extreme-Halophyte Scorzonera Hieraciifolia, Cansu Altuntaş, Rabi̇ye Terzi̇

Turkish Journal of Botany

Halophytes adapting to live in salinized areas can activate some tolerance mechanism through signal compounds to cope with salinity. However, the role of co-activity of signal compounds in salt tolerance of halophytes has not yet fully understood. We researched the changes in signal compounds involved in the salt tolerance mechanism, including inorganic ions, osmoprotectants and substances related to the antioxidant system in

Effects Of States’ Laws On Youth Physical Activity Participation And Obesity Prevalence, Chae Young Chang

Midwest Social Sciences Journal

The alarming prevalence of obesity and lack of physical activity among adolescents led to immediate policy action to address these concerns. Accordingly, many states introduced and enacted their own legislation to encourage physical activity in schools. Few studies have explored the effectiveness of the new legislation, however, especially at the state level. To answer the fundamental question of whether policy is effective and to describe the varying effects of state obesity policies, this study analyzed the Youth Risk Behavior Surveillance System from 2007 to 2017. Using the difference-in-differences method, this study found that legislative efforts to encourage physical activity had …

2020 Domestic Legislative Review, Tara Cooley

Animal Law Review

The 116th Congress, second session, began January 3, 2020, and ended January 3, 2021. While Congress voted on key animal-related legislation, such as the Big Cat Public Safety Act, the COVID-19 pandemic slowed -- or even halted -- proposed legislation at the federal and state levels. Despite the slowdown, local voters proposed and enacted several key initiatives, including the California Ecosystems Protection Act and Orange County, Florida's Right to Clean Water initiative.9 In addition, federally enacted COVID-19-related legislation, such as the Coronavirus Aid, Relief, and Economic Security (CARES) Act, also addressed animalrelated issues. The World Health Organization (WHO) labeled COVID-19 …

Race Youth In Twentieth-Century American Literature And Culture, Claire E. Lenviel

Theses and Dissertations--English

Race Youth in Twentieth-Century American Literature and Culture argues for the centrality of black youth, both real and literary, to the trajectories of African American literature and its repudiation of white supremacy. Drawing on research into the rise of the adolescent and teenager as distinct social categories, I argue that age-based subjectivity should inform how we read race-based subjectivity. My first chapter explores how early twentieth-century black periodicals push back against white supremacist theories of human development in an explicit appeal to what I call “race youth,” the children and adolescents who would take up the mantle of racial uplift. …

Biofortification Of Sodium Selenate Improves Dietary Mineral Contents And Antioxidant Capacity Of Culinary Herb Microgreens, Rachel G. Newman, Youyoun Moon, Carl E. Sams, Janet C. Tou, Nicole L. Waterland

Faculty & Staff Scholarship

Selenium biofortification of plants has been suggested as a method of enhancing dietary seleniumintake to prevent deficiency and chronic disease in humans, while avoiding toxic levels of intake. Popular herbs such as basil (Ocimum basilicum L.), cilantro (Coriandrum sativum L.), and scallions (Allium fistulosum L.) present an opportunity for biofortification as these plants are used for added flavors to meals and are available as microgreens, young plants with increasing popularity in the consumer marketplace. In this study, basil, cilantro, and scallion microgreens were biofortified with sodium selenate under hydroponic conditions at various selenium concentrations to investigate the effects on yield, …

Internet Journal of Allied Health Sciences and Practice

Purpose: The purpose of this study was to describe student perceptions of their learning following experiential learning (EL) activities in a foodservice management course. Nutrition and dietetics education programs have a range of competencies students must learn and demonstrate throughout their curriculum. Learning styles differ amongst students and research has demonstrated they prefer to engage in EL (direct experience) activities to develop their knowledge. Foodservice management is one area of the curriculum that teaches students the basic functions of management; planning, organizing, directing, controlling, and staffing related to food, materials, facilities, and human resources. While this can be taught didactically, …

Refreshment On The Rails: The Law Of Food And Beverage Aboard America's Trains, Adrian Untermyer

Transportation Law Journal

During the golden years of American railroading, passengers could devour lobster salad sandwiches in the dining car and craft cocktails at the bar. But when planes largely replaced trains, fine dining and imbibing on the rails became as rare as a steam locomotive - and the law governing railroad food and beverage remained tangled in a forgotten, complex, and often contradictory jurisdictional thicket.

With passenger railroads now key to tackling climate change, congestion, and sprawl, fine refreshments could help lure Americans back to the rails once more. Therefore, this Article seeks to answer the question ""Who exactly regulates America's railroad …

Prevention Of The Oncogenic Effects Of Lifestyle-Associated Advanced Glycation End-Products (Ages) Via Regular Physical Activity, Bradley A. Krisanits

MUSC Theses and Dissertations

Interrelated lifestyle factors such as a sedentary habit, obesity and diets consisting of highly processed, high protein and fat containing foods, contribute to the accumulation of reactive metabolites known as advanced glycation end-products (AGEs). AGE pathogenic effects are mediated through modification of protein function, genetic fidelity, stress responses, and aberrant cellular signaling. For the first time, this study examined the effects of dietary AGE consumption on cancer progression in vivo and assessed physical activity (PA) as a potential intervention to reduce dietary AGE mediated effects. Given the links between lifestyle and AGEs, we propose that a diet high in AGEs …

Caregiver Knowledge, Perceived Self-Efficacy, And Level Of Confidence In Limiting Bedtime Screen Use In Preschoolers, Emily Hollingsworth

Honors Theses

Screen time usage is a major factor leading to negative behavioral and health consequences in young children. Screen time also affects sleep, with prior research showing a significant association between screen time, particularly at bedtime, and reduced sleep duration and increased sleep problems. The initial aim of this research was to measure and attempt to increase, through an educational intervention, the knowledge, perceived self-efficacy, and confidence of study participants/primary caregivers with regard to limiting the bedtime screen use of their preschoolers with the goal of health promotion. It was intended to be a quantitative, quasi-experimental, multi-site, pre- post-intervention case study. …

Ogt Glycosylation Of Histones In T Cells May Participate In Systemic Lupus Erythematosus, Jared Luke Ridgeway

Honors Theses

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease that primarily affects women. The etiology is not known yet, but genetics and environmental factors trigger the disease. These epigenetic changes modify gene expression and contribute to the development of the disease. It is known that T cells from patients with lupus overexpress genes that may contribute to the onset and progression of the disease. Dr. Gorelik has shown that OGT (O-linked N-acetyl-Glucosamine Transferase), which is an X-linked gene, is overexpressed in women with SLE. OGT adds b-N-acetylglucosamine (O-GlcNAc) to serine and threonine residues of proteins. …

Proactive Management Of Acute Oedema Following Hand And Minor Burn Injury, Dale O. Edwick

Theses

Burn injury is a unique trauma. The inflammatory process initiated with burn injury adversely influences all of the Starling equation variables, resulting in increased transvascular fluid filtration, so that oedema as a product of burn injury is more readily formed than in other forms of trauma. Localised wound oedema forms due to minor burn injury, with increasing systemic oedema associated with increased size of burn. It is now recognised that a marked inflammatory and immune response is created with non-severe burn injury, indicating a systemic component with all burns. The effect of oedema formation on the course of the burn …

Statistical Methods For Evaluating Confounding In Nutritional Epidemiology: Examining The Association Of Dietary Measures And Incident Type 2 Diabetes, Stephanie E. Tison

All ETDs from UAB

Nutrition is a key factor in the development of noncommunicable diseases (NCDs) such as cardiovascular disease, diabetes, obesity, and cancer, which are continuing to increase globally. Research on dietary patterns is crucial for informing what aspects of diet are most critical for preventing and possibly reversing chronic disease. Dietary patterns focus on the types of food that are consumed which reflects the complexity and cultural aspects of diet rather than focusing on a single food or nutrient. Observational cohort studies are able to observe typical dietary intake and thus better reflect the real association between diet and chronic disease. In …
