Electrical Sensing In Non-Excitable Cells To Promote Galvanotaxis And Tissue Survival, Anyesha Sarkar

Electronic Theses and Dissertations

Weak DC fields have been shown to induce polarity, cell migration and cell proliferation in 2D cultures in vitro. To understand the mechanism by which non-excitable cells sense such weak EFs, we have investigated the mechanism of cathode-directed water flow (electro-osmosis) in the boundary layer of cells by reducing it with neutral, viscous polymers. Our results indicate that low molecular weight polymers decrease cathodal migration and promote anodal migration in a concentration dependent manner. High molecular weight polymers do not affect directionality and can be explained using porosity and hydraulic permeability between the polymers. These results provide the first evidence …

The Role Of The Auxin Biosynthesis And Signaling In Soybean Root Nodule Development, Mucahid Bozkus

Electronic Theses and Dissertations

Nitrogen(N) is one of the most important plant nutrients for plant growth and yield, however, its abundance in the soil is not sufficient for profitable crop production. The use of chemical fertilizers helps address soil N deficiency in agriculture. However, due to the environmental pollution resulting from excessive use of fertilizers, alternative forms of N for agriculture are a necessity. Leguminous plants such as soybean (Glycine max) form a symbiotic association with N-fixing rhizobia to meet their N demands. Legume-rhizobia symbiosis results in the formation of unique structures called nodules where rhizobia convert atmospheric nitrogen into plant usable forms, thus …

Rational Design Of Advanced Functional Materials For Electrochemical Devices, Shun Lu

Electronic Theses and Dissertations

In recent years, there has been a fast-growing trend in developing urea (CO(NH2)2) as a substitute H2 carrier in energy conversion due to its high energy density, nontoxicity, stability, and nonflammability. Urea, a byproduct in the metabolism of proteins and a frequent contaminant in wastewater, is an abundant compound that has demonstrated favorable characteristics as a hydrogen-rich fuel source with 6.7 wt % gravimetric hydrogen content. Also, there is 2-2.5 wt % urea from mammal urine; therefore, 0.5 million ton of additional fuels will be produced per year just from human urine (240 million ton each year). Electrochemical oxidation has …

Biomechanical Investigation Of Plant Vascular Tissue For Bio-Inspired Design And Flexible Composites, Mukesh Roy

Electronic Theses and Dissertations

Since the inception of evolution, nature has continuously optimized all the natural materials. These optimizations are so efficient that scientists and engineers have started taking inspiration from nature. Such inspiration-based solutions provide sustainable development of new materials with enhanced structural properties and functionalities (such as stiffness, stability, toughness, self-healing etc.). This variety of properties and functionalities is mainly due to the hierarchical organization of such components. Abstraction of the hidden cues of the hierarchical organization, principles and underlying structure-function relations are some of the critical approaches of bioinspired materials design. Inspiration from animals and plants has helped develop the design …

Pheasant Ecology In An Agricultural Landscape Of South Dakota, Sprih Harsh

Electronic Theses and Dissertations

Habitat loss and fragmentation are the greatest threats to wildlife conservation. Grasslands are among the most threatened ecosystems worldwide. The large-scale conversion of North American grasslands to cultivation has been strongly associated with declines of grassland bird populations. The ring-necked pheasant (Phasianus colchicus) is a common grassland bird which is negatively impacted by the conversion of grassland to cropland. Though pheasants are non-native to South Dakota, they have become naturalized in most of the state. However, with increases in agricultural intensification in South Dakota, indices of pheasant abundance from brood route surveys suggest that pheasant populations have declined to historically …

An Evaluation Of The Bighorn Sheep Population In Badlands National Park, Austin J. Wieseler

Electronic Theses and Dissertations

Within the last century, bighorn sheep (Ovis canadensis) in the badlands ecosystem of western South Dakota have been subjected to complete extirpation, reintroduction, disease die-offs, genetic bottlenecking, and population augmentation. Subsequently, the population in Badlands National Park (BNP) appears to have recovered, but it was unknown to what degree past events had influenced the population. From 2017-2019, we conducted research on 5 subherds within 2 management units in BNP to 1) survey for the presence of respiratory pathogens and estimate the prevalence of other potentially infectious diseases; 2) assess adult and lamb survival and cause-specific mortality; 3) estimate population size …

Improving Nutritional Properties And Extractability Of Pea Proteins For Human Consumption Via Fungal Bioprocessing, Camille Massmann

Electronic Theses and Dissertations

Yellow peas are a rich source of protein and phytochemicals. Peas are compatible with many diets restricted by sensitivities, allergies, or personal choice. As a result, peas are gaining popularity in food markets, despite the challenges they present. The biggest challenges for pea proteins in food markets are high content of fiber, starch, and saponins. These components cause processing challenges and create undesirable textures and bitter flavors. Pea proteins are typically extracted with alkaline extraction or air classification methods which result in 80% and 50% protein products respectively. With low protein purity, these products are not competitive with other, more …

Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding

Electronic Theses and Dissertations

Cortisol is known as the stress hormone, as it influences many metabolic processes to maintain glucose homeostasis during stressful experiences, including physical and psychological stress. It can be detected in biological matrices such as blood and hair and is released rapidly during sudden stressors and continuously during longterm stress. Blood cortisol fluctuates rapidly in response to acute stressors like pain, exertion, and fear; in hair cortisol accumulates steadily over the period of hair growth and may be useful for detecting chronically elevated cortisol resulting from long-term stress. The objective of this research was to, 1) determine the influence of a …

Genome-Wide Association Analysis Permits Characterization Of Stagonospora Nodorum Blotch (Snb) Resistance In Hard Winter Wheat, Rami Altameemi

Electronic Theses and Dissertations

Stagonospora nodorum blotch (SNB) is an economically important wheat disease caused by the necrotrophic fungus Parastagonospora nodorum. SNB resistance in wheat is controlled by several quantitative trait loci (QTLs). Thus, the identifying of novel resistance/susceptibility QTLs is crucial for continuous improvement of the SNB resistance. Here, the hard winter wheat association mapping panel (HWWAMP) comprising accessions from breeding programs in the Great Plains region of the US, was evaluated for SNB resistance and necrotrophic effectors (NEs) sensitivity at the seedling stage. A genome-wide association study (GWAS) was performed to identify singlenucleotide polymorphism (SNP) markers associated with SNB resistance and …

Self-Determination Theory As A Suitable Theoretical Basis And Measurement Approach For Psychodrama Interventions, Ozge Kantas, Aliye Mavili

Psychology Faculty/Staff Publications

Psychodrama as a group therapy and intervention technique is based on role-plays as a way of rehearsing life. It has 100 years of history, and it has been widely used in different life domains and purposes since then. On the other hand, sometimes it has been criticized for lacking the methodological rigor of modern psychological science. Qualitatively and quantitatively, including a case study, we aim to show the effectiveness of psychodrama using a motivational science framework theoretically and empirically. We discuss why psychodrama is effective from an applied social psychological perspective—that is, to demonstrate that psychodrama fits well with self-determination …

Contribution Of The Human Microbiome And Proteus Mirabilis To Onset And Progression Of Rheumatoid Arthritis: Potential For Targeted Therapy, Jessica Kerpez, Marc Kesselman, Michelle Demory Beckler

Internet Journal of Allied Health Sciences and Practice

The human microbiome has been shown to play a role in the regulation of human health, behavior, and disease. Data suggests that microorganisms that co-evolved within humans have an enhanced ability to prevent the development of a large spectrum of immune-related disorders but may also lead to the onset of conditions when homeostasis is disrupted. In many conditions, a link between dysbiosis (microbial imbalance or microbiome upset) has been identified and associated with immune conditions such as rheumatoid arthritis (RA). This review provides insight into how an individual’s unique microbiome, combined with a genetic predisposition and environmental factors may lead …

Introduction - Multiculturalism, Communication, And Critical Citizenship Studies, Hsin-I Cheng

Communication

Since 2015, the movements of refugees and migrants have intensified discussions on citizenship in both Eastern and Western societies. The image of Aylan, a three-year-old Syrian boy lying on a beach, triggered global conversations on citizenship, borders, and nationhood. In Germany, Chancellor Merkel worked swiftly on refugees’ settlement in German society and encountered much resistance. In the United States, discussions of policies to curtail immigrants, migrants, and refugees became heated after the 2016 presidential election. In Taiwan, given the country’s ethnic diversity and politically controversial status as a nation-state, political economists urged the government to accept and treat refugees and …

Brain-Computer-Interfacing & Respondeat Superior: Algorithmic Decisions, Manipulation, And Accountability In Armed Conflict, Salahudin Ali

Catholic University Journal of Law and Technology

This article examines the impact that brain-computer-interfacing platforms will have on the international law of armed conflict’s respondeat superior legal regime. Major Ali argues that the connection between the human brain and this nascent technology’s underlying technology of artificial intelligence and machine learning will serve as a disruptor to the traditional mental prerequisites required to impart culpability and liability on commanders for actions of their troops. Anticipating that BCI will become increasingly ubiquitous, Major Ali’s article offers frameworks for solution to BCI’s disruptive potential to the internal law of armed conflict.

Picosecond Pulsed Electric Fields And Promise In Neurodegeneration Research, Martina Zamponi, Ross Petrella, Peter A. Mollica

School of Medical Diagnostics & Translational Sciences Publications

The delivery of pulsed electric fields to biological cells for regenerative research and therapeutic applications is a field that has been widely explored. Picosecond pulsed electric fields have been shown to induce intracellular effects and directly target cell membrane proteins as well as being able to induce cell permeabilization and death by apoptosis. Additionally, ultrashort pulses can be focused and delivered in a noncontact manner for possible targeting of deep and inaccessible tissues. The unique characteristics of picosecond pulses make them a possible approach for treatment of Huntington's and Alzheimer's diseases, both characterized by progressive neuronal degeneration and death, and …

Simulation Of A Rat Muscle-Tendon Unit With Hill-Type Model Dynamics And The Study Of Viscoelasticity In A Collagen Molecule Via Molecular Dynamics, Veronica Siko

West Chester University Master’s Theses

The field of biological science has established that tendons transfer muscular forces to adjacent bones, but there is a dearth of information about the underlying physical principles of these interactions and how the property of viscoelasticity (displayed in tendons as a difference in mechanical response to stress with differing stretching rates) is encompassed in the collagen of tendons. This thesis details the results of concentric and eccentric contractions of the rat muscle-tendon unit (MTU) with and without viscoelasticity (concentric contraction requires active shortening of the muscle, while eccentric contraction requires active lengthening of the muscle) (Lovering & Brooks, 2014). Once …
