Role Of The Acid Sensing Ion Channel 1a In The Systemic Circulation, Selina M. Garcia

Biomedical Sciences ETDs

Acid-sensing ion channel 1a (ASIC1a) is a non-selective cation channel that is expressed in vascular smooth muscle cells. However, little is known about the contribution of ASIC1a to vascular reactivity and cardiovascular homeostasis. We have previously shown that ASIC1a contributes to pulmonary vascular smooth muscle cell (VSMC) Ca²⁺ entry and vasoconstriction as well as chronic hypoxia-induced pulmonary hypertension. However, a role of ASIC1a in the systemic circulation is unclear. Previous reports have shown that ASIC1a is expressed in femoral and cerebral arteries, however, these studies suggest that ASIC1a contributes to vascular reactivity through neuronal regulation rather than vascular. Therefore, …

The Role Of Anti-Inflammatory Cytokine Interleukin-10 (Il-10) In Tauopathies, Lea L. Weston

Biomedical Sciences ETDs

Tauopathies are neurodegenerative diseases, including Alzheimer’s disease, that are associated with pathological accumulation of the microtubule associated protein tau (MAPT, or tau) (Lee et al., 2001). Abnormal hyperphosphorylated tau (pTau) strongly correlate with cognitive impairment (Nelson et al., 2012). Neuroinflammation is also associated with tauopathies (Gerhard et al., 2006b; Edison et al., 2008) and is implicated in driving tau pathology (Yoshiyama et al., 2007, Maphis et al., 2015b). Therefore, it is compelling to understand the role of anti-inflammatory cytokines in limiting neuroinflammation and tau pathology. Interleukin-10 (IL-10) is a well-established anti-inflammatory cytokine with roles in limiting inflammation in the central …

When The Clinical Environment Is Closed To Students: The Harsh Reality Of Covid-19 And Implications For Colleges Of Osteopathic Medicine, Ken Heiles, Valerie Sheridan, Tami Hendriksz, Rebecca Giusti, Tyler C. Cemet

Faculty and Staff Publications

When the World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19) a global health emergency, Colleges of Osteopathic Medicine (COMs) debated the role of medical students during this developing pandemic. Initially, the discussion included whether medical students were essential personnel contributing to meaningful patient care. Many questions arose regarding how COVID-19 would affect medical education and if the changes would be temporary or continue for a significant period of time. Due to the lack of availability of personal protective equipment (PPE) and a decreased focus on clinical education within many healthcare settings, in March the American Association of Colleges of …

The First-Year Experiences Of Students In Remedial Classes At A Research University: Implications For Retention And Support, Therese Baca-Radler

Language, Literacy, and Sociocultural Studies ETDs

As more institutions of higher education adopt non-selective admissions processes, an increasing number of students from underrepresented populations are placed into developmental intervention courses as an added requirement to their educational paths based on standardized test scores alone. This study interviewed students who had these requirements imposed upon them and sought to understand their thoughts and feelings about that placement and how it impacted their transition from high school to college and their first-year college success. As students described their prior experiences in formal academic settings, they emphasized the benefits of family support in building their self-directed learning skills and …

Numerical Evaluation Of Effective Thermal Response Of Heterogeneous Materials, Kevin W. Irick

Mechanical Engineering ETDs

Heterogeneity in materials leads to increased complication of physics, at the level or scale where heterogeneity exists, making analysis and material behavior predictions more difficult. As a result of the intricate descriptions or understanding of the physics required to determine the behavior of a heterogenous material or system, practitioners frequently prefer the use of effective properties or responses. This body of work is dedicated to performing computational analyses on the thermal behavior of heterogeneous materials and evaluating the corresponding analyses using formal verification approaches. Custom finite element method code was used for solving the heat equation in a variety of …

Solar Insolation Micro-Forecasts Using Longwave Infrared Sensors And Artificial Intelligence, Anthony R. Menicucci

Mechanical Engineering ETDs

Solar Insolation Micro-Forecasts (SIMF) are used by Independent Service Operators (ISOs) and other grid operators to maintain constant and stable electrical grid frequency, voltage, power factor and waveform across their transmission infrastructure. Intermittent, thick, dense and typically cumulus clouds negatively impact the electrical grid by quickly turning on and off power production from large solar photovoltaic (PV) fields, causing grid stability problems between generation and load. Forecasting insolation values over large PV fields allows operators the chance to anticipate and proactively implement mitigation strategies like engaging spinning reserve from gas turbines, deploying generators, buying power in the spot market, and …

The Impact Of Calendering On The Electronic Conductivity Heterogenity Of Lithium-Ion Electrode Films, Emilee Elizabeth Hunter

Theses and Dissertations

Advancements in Li-ion batteries are needed especially for the development of electric vehicles and stationary energy storage. Prior research has shown mesoscale variations in electrode electronic conductive properties, which can cause capacity loss and uneven electrochemical behavior of Li-ion batteries. A micro-four-line probe (μ4LP) was used to measure electronic conductivity and contact resistance over mm-length scales in that prior work. This work describes improvements to overcome the challenge of unreliable surface contact between theμ4LP and the sample. Ultimately a second generation flexible probe called the micro-radial-surface probe (μ4LP) was designed and produced. The test fixture was also optimized to obtain …

Durability Of Concrete Confined With Gfrp Tube., W. Fahmy, A. Heniegal

Mansoura Engineering Journal

One promising innovative structural system is concrete-filled fibre reinforced polymer (FRP) tubes, which provide many unique advantages. The FRP tube acts as a stay-in place structural formwork to contain the fresh concrete, which may save the costs of . formwork and labour used by cast-in-place or pre-cast industries. At the same time, the FRP tube acts as a non-corrosive reinforcement for the concrete for flexure and shear. More importantly, the FRP lube provides confinement to the concrete in compression. which significantly improves the strength and ductility. The contained concrete is protected from severe environmental effects and deterioration resulting from moisture …

Evaluation And Prediction Of Structural Properties Of Asphalt Concrete., Mohamed Abdel-Motaleb

Mansoura Engineering Journal

The ability to characterize paving materials in terms of fundamental properties is becoming increasingly more important. This is partially due to the fact that many agencies are beginning to use pavement design system based on elastic theory. The most required inputs in the elastic theory are Elasticity modulus (E) and Poisson's ratio (u) of asphalt layer. So, the current study is primarily concerned with simplifying a technique that can be used, in pavement design phase, for predicting the expected structural properties of asphalt layer at the actual temperature and loading rate of traffic. To achieve this objective, many paving mixes …

Mansoura Engineering Journal

The seabed changes around the pile breakwater were examined experimentally. The breakwater consists of vertical double rows of closely spaced circular piles. This is for determining the additional embedded length of the pile in the soil due to scour caused by the wave action. The seabed hydrography was recorded and the maximum scour and maximum deposition were determined for different wave conditions. Intermediate and shallow water waves were applied. It is concluded that the seabed scour reaches the maximum value when the dimensionless wave number ranged between 0.5 and 1.0 under the experiment conditions. The relative maximum scour depths around …
