Biology, Monitoring, Sampling, And Management Of Rice Billbug, Sphenophorus Pertinax, In Furrow-Irrigated Rice, Chase Alan Floyd Dec 2022

Biology, Monitoring, Sampling, And Management Of Rice Billbug, Sphenophorus Pertinax, In Furrow-Irrigated Rice, Chase Alan Floyd

Graduate Theses and Dissertations

Furrow-irrigated rice hectares have increased annually for the last five years in the predominant long-grain rice producing states. Initial implementation of the system began in the 1980’s, but lack of rice blast (Magnaporthe grisea, Hebert) resistant cultivars made the system a nonviable option for rice producers. Hybridization of rice cultivars with less susceptibility has begun to increase the interest of producers to implement a furrow-irrigated rice production system due to the cost saving opportunities that it may provide. Elimination of the flood from large sections of the rice fields in a furrow-irrigated system alters management strategies and pest complexes compared …


In-Situ Tribology Of Engineered Surfaces With 3d-Printed Micro/Nano-Textures, Mahyar Afshar Mohajer Dec 2022

In-Situ Tribology Of Engineered Surfaces With 3d-Printed Micro/Nano-Textures, Mahyar Afshar Mohajer

Graduate Theses and Dissertations

Surface texturing is an effective way to reduce the adhesion and friction between two contacting surfaces by reducing the real area of contact between them, providing a potential solution for adhesion and friction-induced failures, for example, failures in micro-/nano-electromechanical systems (MEMS/NEMS). Surface texturing is also essential to the realization of functional surfaces such as superhydrophobic/philic and icephobic surfaces. However, textures are prone to deformation due to being subjected to higher contact pressures. The advancement of 3D nanoprinting by two-photon lithography (TPL), combined with the ability to make an in-situ observation of the interplay between the forces and the sliding surfaces …


Dream Border, Pardis Ahmadpour Mobarake Dec 2022

Dream Border, Pardis Ahmadpour Mobarake

Graduate Theses and Dissertations

Dream Border is the result of my lived experience of relocation. The exhibition addresses the duality of being on the border between reality and imagination. In this place, the present, past, and future exist simultaneously. By engaging with personal narratives, childhood memories, as well as Iranian cultural and literary visual elements, I search for universal concepts in relocation. These works evoke the imposition of power and the many phenomena that the contemporary world endures despite globalization, such as anxiety, fear, and oppression on a small or large scale, which compel people to relocate. Uncertainty in the process of migration and …


Evaluation Of Biological And Chemical Seed Treatments For Management Of Rice Diseases, Sherif Adam Sharfadine Dec 2022

Evaluation Of Biological And Chemical Seed Treatments For Management Of Rice Diseases, Sherif Adam Sharfadine

Graduate Theses and Dissertations

Rice is the primary staple for more than half of the global population and is the second most important cereal worldwide. In the US, rice is primarily grown in the southern states, with Arkansas leading production and responsible for 47% of the total rice production in the country. Diseases cause significant yield losses in rice. Sheath blight, rice blast and bacterial panicle blight are the main diseases in rice and cause significant yield losses. Sheath blight alone could cause up 50% yield loss in heavily damaged fields with highly susceptible cultivars. Additionally, rice seed and seedling diseases primarily caused by …


Evaluating Arkansas Weathering Steel Bridge Performance, Yessenia Gonzalez Dec 2022

Evaluating Arkansas Weathering Steel Bridge Performance, Yessenia Gonzalez

Graduate Theses and Dissertations

Weathering steel enhances corrosion-resistant steel features over conventional steel when a patina properly forms on the weathering steel surface. Weathering steel is a low carbon steel of less than 0.3% carbon by weight and has a chemical composition including other alloying elements such as nickel, copper, and chromium that develops a patina. The patina is a dense protective oxide film layer that develops on the steel member surface. The patina defends the steel from corrosion by preventing moisture, oxygen, and contaminant penetration. However, long periods of moisture and deicing chemicals applied during wet wintry conditions hinder proper patina formation. Without …

Flood Hazard And Risk Analyses In The Republic Of Panama: A Case Study From The Juan Diaz River Watershed In Panama City, Virgilio De Jesus Quintero

Graduate Theses and Dissertations

Flooding is the natural hazard with most occurrences in Panama. Its frequency and magnitude have increased over the years. This dissertation analyzes Panama’s flood activity in order to better understand flood hazards, the current evolution of Panamanian perceptions of flood risk, and the incorporation of indigenous knowledge used to mitigate flood hazards. The first chapter developed a baseline of past and current flood inventory in Panama, which required the use of flood historical data, thematic cartography, and Geographic Information Science (GIS). This chapter shows Panama has experienced floods in varying degrees. Through the spatial and temporal distribution of floods from …


Interfacial Engineering Of Nickel-Rich Layered Oxide Cathodes Via Atomic Layer Deposition (Ald), Xin Wang Dec 2022

Interfacial Engineering Of Nickel-Rich Layered Oxide Cathodes Via Atomic Layer Deposition (Ald), Xin Wang

Graduate Theses and Dissertations

Layered nickel-rich cathodes LiNixMnyCozO2 (NMCs, x + y + z =1, x ≥ 0.6) are regarded as one of the most promising cathode materials for next-generation lithium-ion batteries (LIBs), given their remarkably reduced cost and increased capacity compared to the conventional LiCoO2 cathode. However, the deployment of these Ni-rich cathodes has been hindered by the continuous loss of practical capacity and reduction in average working voltage, inherently due to their interfacial, structural, and thermodynamic instability. To address these issues, interfacial engineering via surface modification has been well-recognized as an effective strategy and a large number of coating materials have been …


Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri Dec 2022

Improving Building Cfd Peak Pressure Computation Using Les With A Focus On Inflow Turbulence Methods And Grid Spacing Size., Zahra Mansouri

Graduate Theses and Dissertations

Structural failures by extreme winds often leads to economic losses and even deaths. Proper design of buildings requires accurate estimation of wind loads to prevent structural damage. Using routine guidelines generally leads to the underestimation of buildings’ peak pressures, in which most failures occur. To estimate wind loads more accurately three different methods (i.e., field measurement, wind tunnel (WT), and computational fluid dynamics (CFD)) are in use. A well-validated CFD provides more flow field details at lower costs compared to field measurements and WT. As strong winds are extremely turbulent, the effects of turbulence in wind should be incorporated into …


Evaluation Of Chrysodeixis Includens Nucleopolyhedrovirus (Chinnpv) Formulations For Soybean Looper (Chrysodeixis Includens) Control In Soybean, Caleb Robert Rice Dec 2022

Evaluation Of Chrysodeixis Includens Nucleopolyhedrovirus (Chinnpv) Formulations For Soybean Looper (Chrysodeixis Includens) Control In Soybean, Caleb Robert Rice

Graduate Theses and Dissertations

Chrysodeixis includens Nucleopolyhedrovirus (ChinNPV) specifically Chrysogen, has been commercially available in South America since 2016 but is not current available in the U.S. Chrysogen targets soybean looper (Chrysodeixis includens) (SBL), the major defoliator of soybean (Glycine max (L.) Merrill) in the mid-southern region of the U.S. Experiments were conducted during the 2020 and 2021 growing seasons to evaluate effectiveness of three formulations of Chrysogen at multiple rates for control of SBL. Soybean looper larvae used for following experiments were kept in an insect incubator at the University of Arkansas Lonoke Research and Extension Center. The first objective was to evaluate …

Effects Of Participation In Athletics And Music Ensembles By Socioeconomic Status On Arkansas Academic Achievement, Aaron Leverette Dec 2022

Effects Of Participation In Athletics And Music Ensembles By Socioeconomic Status On Arkansas Academic Achievement, Aaron Leverette

College of Education Dissertations

Schools are held accountable by mandated standardized testing measuring academic achievement. Due to limited budgets, administrators have to decide how to balance funding for athletic teams and school music ensembles versus additional programs and positions that directly support academic achievement in tested subjects. The purposes of this study were to determine, after controlling for previous achievement, the effects by socioeconomic status between students who participate in athletics only versus school music ensembles only versus both versus neither on mathematics, English, reading, and science achievement measured by ACT Aspire Summative Assessments in mathematics, English, reading, and science for eighth-grade students in …

Cardiac contractile strength is recognised as being highly pH-sensitive, but less is known about the influence of pH on cardiac gene expression, which may become relevant in response to changes in myocardial metabolism or vascularization during development or disease. We sought evidence for pH-responsive cardiac genes, and a physiological context for this form of transcriptional regulation. pHLIP, a peptide-based reporter of acidity, revealed a non-uniform pH landscape in early-postnatal myocardium, dissipating in later life. pH-responsive differentially expressed genes (pH-DEGs) were identified by transcriptomics of neonatal cardiomyocytes cultured over a range of pH. Enrichment analysis indicated “striated muscle contraction” as a …


Identification Of Clinical And Behavioral Outcomes Predictive Of Ftld-Tdp Pathology, Nevin Crow, Virginia A. Berry, Eric Febles Dec 2022

Identification Of Clinical And Behavioral Outcomes Predictive Of Ftld-Tdp Pathology, Nevin Crow, Virginia A. Berry, Eric Febles

Science University Research Symposium (SURS)

Frontotemporal Lobar Dementia (FTLD) is a neurogenerative disease often misdiagnosed as Alzheimer’s Disease (AD), resulting in poor treatment outcomes (Rascovsky et al., 2011). Multi-factorial approaches are increasingly being applied to yield more accurate and earlier diagnoses. These standard clinical outcomes include MRI imaging, biomarkers, and assessments of cognitive ability. While each of these outcomes are partially predictive of FTLD diagnosis, none alone carry enough power to differentiate FTLD patients from other dementias, including AD. One notable variable is TDP-43, a DNA-binding protein involved in regulating the FTLD risk gene UNC13A, suggested as one of the more effective biomarkers for early …
