Corn Grain Alternatives And Coated Versus Non-Coated Trenbolone Acetate And Estradiol Impants For Feedlot Finishing Animals: Influence On Growth Performance, Carcass Characteristics, Efficiency Of Dietary Net Energy Utilization, Beef Production Per Hectare And Digestiblilty, Elizabeth Buckhaus
Electronic Theses and Dissertations
Corn grain alternatives are often not used in finishing rations due to reduced caloric densities and reluctance to deviate from traditional methods. Along with optimum nutrition, cattle need to have proper implant strategies to reap maximum returns on investment. Two studies were conducted to evaluate the effects of corn grain alternatives and implant type on feedlot finishing cattle. The objective of the first study was to determine the influence of corn silage (15% or 30% dry matter inclusion), and terminal implant type (coated or non-coated) containing equal hormonal doses on animal growth performance, apparent total tract digestibility, beef production per …

Assessing The Effectiveness Of Cfd To Solve An Inverse Problem Of Thermal Profiles For The Protodune-Sp Neutrino Detector, Cecilia Anne Streff
Electronic Theses and Dissertations
Computational fluid dynamics (CFD) is a branch of fluid mechanics which is employed to numerically solve complex fluid, heat transfer, and multiphysics problems. Traditionally, CFD techniques are used to solve “forward” problems—using some known information of a system as inputs to a representative model to predict experimental measurements or expected system behavior. The work presented here demonstrates how CFD may be used to solve an “inverse” problem—given limited experimental data and some model, predict (previously unidentified) “input” system (or system model) parameters. The case study for this research uses a validated CFD modeling approach of the liquid argon (LAr) region …

Study On The Human Gut Bacteria Under Different Ecological Conditions: Antibiotic Perturbation And Dietary Quercetin, Shruti Shashidharan Menon
Electronic Theses and Dissertations
The human intestine encompasses a vast community of microorganisms known as the gut microbiota that play a crucial role in maintaining health. Common perturbations such as changes in the normal diet, antibiotic treatment, and changes in environmental conditions can alter the gut microbiome. This can create dysbiosis in the gut leading to disease conditions. Therefore, it becomes important to determine the forces that influence the gut microbial ecology. In the first study, we focus on antibiotic perturbations on microbial succession and resilience in a synthetic consortium consisting of the most prevalent gut bacteria in humans. In addition, we investigated the …

Human Activity Recognition Based On Wearable Flex Sensor And Pulse Sensor, Xiaozhu Jin
Electronic Theses and Dissertations
In order to fulfill the needs of everyday monitoring for healthcare and emergency advice, many HAR systems have been designed [1]. Based on the healthcare purpose, these systems can be implanted into an astronaut’s spacesuit to provide necessary life movement monitoring and healthcare suggestions. Most of these systems use acceleration data-based data record as human activity representation [2,3]. But this data attribute approach has a limitation that makes it impossible to be used as an activity monitoring system for astronavigation. Because an accelerometer senses acceleration by distinguishing acceleration data based on the earth’s gravity offset [4], the accelerometer cannot read …

Quantifying The Benefits Of The Expanded Food And Nutrition Education Program (Efnep) Using Biomarkers For Chronic Disease Risk, Richard Acquah-Sarpong
Electronic Theses and Dissertations
The Expanded Food and Nutrition Education Program (EFNEP) is among the major nutrition education programs funded by the United States Department of Agriculture (USDA) with the aim of reducing food insecurity among low-income families. The program reaches about 70,000 adults and youth of low-income families in the US, District of Columbia, and six U.S. territories. Prior studies have used self-reported data, which possesses measurement errors, to estimate the benefits of the program. This can lead to underestimation or overestimation of results. To address this limitation, I use clinically measured objective biomarkers, such as body mass index (BMI), blood sugar level …
Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda
Classification And Evaluation Of Extended Pics (Epics) On A Global Scale For Calibration And Stability Monitoring Of Optical Satellite Sensors, Juliana Maria Fajardo Rueda
Electronic Theses and Dissertations
As targets for the calibration and monitoring of optical satellite sensors, historically stable areas across North Africa have been used, known as Pseudo Invariant Calibration Sites PICS. However, two major drawbacks exist for these sites; first is the dependency on a single location to be always invariant, and second is the limited amount of observation achieved using these sites. As a result, longer time periods are needed to construct a dense data set to assess the radiometric performance of on-orbit optical sensors, and be convinced that the change detected is sensor-specific rather than site-specific. This work presents a global land …
Comparison Of Software Packages For Detecting Differentially Expressed Genes From Single-Sample Rna-Seq Data, Rong Zhou
Electronic Theses and Dissertations
RNA-sequencing (RNA-seq) has rapidly become the tool in many genome-wide transcriptomic studies. It provides a way to understand the RNA environment of cells in different physiological or pathological states to determine how cells respond to these changes. RNA-seq provides quantitative information about the abundance of different RNA species present in a given sample. If the difference or change observed in the read counts or expression level between two experimental conditions is statistically significant, the gene is declared as differentially expressed. A large number of methods for detecting differentially expressed genes (DEGs) with RNA-seq have been developed, such as the methods …
Cascaded Deep Learning Network For Postearthquake Bridge Serviceability Assessment, Youjeong Jang
Cascaded Deep Learning Network For Postearthquake Bridge Serviceability Assessment, Youjeong Jang
Electronic Theses and Dissertations
Damages assessment of bridges is important to derive immediate response after severe events to decide serviceability. Especially, past earthquakes have proven the vulnerability of bridges with insufficient detailing. Due to lack of a national and unified post-earthquake inspection procedure for bridges, conventional damage assessments are performed by sending professional personnel to the onsite, detecting visually and measuring the damage state. To get accurate and fast damage result of bridge condition is important to save not only lives but also costs.
There have been studies using image processing techniques to assess damage of bridge column without sending individual to onsite. Convolutional …

Characterization Of Cucurbitacin-Inspired Estrone Analogues As Novel Inhibitors Of Human Atp- Binding Cassette Proteins (Abcb1 And Abcc1), Jennifer Kyeremateng
Electronic Theses and Dissertations
ATP-binding cassette (ABC) transporters are a large class of integral membrane proteins that contribute to key physiological functions in all organisms by utilizing ATP binding and hydrolysis to transport diverse substrates across membrane barriers. P-glycoprotein (P-gp/ ABCB1) and Multidrug Resistance protein 1 (MRP1/ABCC1) are widely reported ABC transporters associated with multidrug resistance in cancer. Multidrug resistance (MDR) mediated by P-gp and MRP1 is responsible for treatment failures of many metastatic cancers as a result of reduced accumulation, bioavailability and diminished potency of anticancer drugs. Currently, known P-gp and MRP1 inhibitors are limited due to toxicity, lack of selectivity and low …
Development Of A Probabilistic Multi-Class Model Selection Algorithm For High-Dimensional And Complex Data, Madeline Anne Ausdemore
Development Of A Probabilistic Multi-Class Model Selection Algorithm For High-Dimensional And Complex Data, Madeline Anne Ausdemore
Electronic Theses and Dissertations
The development of quantifiable measures of uncertainty in forensic conclusions has resulted in the debut of several ad-hoc methods for approximating the weight of evidence (WoE). In particular, forensic researchers have attempted to use similarity measures, or scores, to approximate the weight of evidence characterized by highdimensional and complex data. Score-based methods have been proposed to approximate theWoE for numerous evidence types (e.g., fingerprints, handwriting, inks, voice analysis). In general, scorebased methods consider the score as a projection onto the real line. For example, the score-based likelihood ratio evaluates and compares the likelihoods of a score calculated between two objects …

The Efficacy Of Neurofeedback In The Treatment Of Individuals With Anxiety-Spectrum Disorders: A Meta-Analysis, Gordon Michael Russo
Electronic Theses and Dissertations
A number of authors have published articles that assert the efficacy of neurofeedback (NFB) in the treatment of people with anxious symptomatology. Despite this, many insurance companies identify NFB as experimental, which prohibits individuals from utilizing benefits to obtain this therapeutic treatment. In order to examine these discrepancies, the present meta-analyses were conducted and guided by research questions designed to examine the overall effectiveness of NFB, the impact of participant characteristics, and identify the if there is a significant difference in anxiety-spectrum outcomes. Twenty-six trials were divided based on design (14 single group [SG]; 12 between group [BG]) and analyzed …

Electronic Theses and Dissertations
Young adults (aged 18-25) were identified as the most stressed age group due to internal and external factors that are relatively unique to their group. High stress levels are alarming as they coincide with a multitude of adverse effects on psychological health, including difficulty falling and staying asleep, reduction in overall sleep quality, and exacerbated depression and anxiety symptomatology. Young adults attending post-secondary education institutions are at particular risk for developing and maintaining these adverse psychological effects of stress, especially considering the low rate in which they seek treatment for psychiatric difficulties. Limited literature exists to date regarding condensing a …

Constructing And Validating Feature Models Using Relational, Document, And Graph Databases, Hazim Shatnawi
Electronic Theses and Dissertations
Building a software product line (SPL) is a systematic strategy for reusing software within a family of related systems from some application domain. To define an SPL, a domain analyst must identify the common and variable aspects of a family of systems and capture them for later use in construction of specific products. To do so, Feature-Oriented Domain Analysis (FODA) introduced the feature model as an abstraction to represent the common and variable aspects, using a feature diagram to depict the model visually. However, this abstraction is often difficult for developers to use because most tools rely on specialized theories, …

A maximum heat transfer enhancement of 102 % was obtained at the channel flow rate of 15 LPM. The fan was …
The Current Treatment Of English Phrasal Verbs In Mext-Authorized Textbooks For Japanese Junior High School Students, Natsuko Yamada
The Current Treatment Of English Phrasal Verbs In Mext-Authorized Textbooks For Japanese Junior High School Students, Natsuko Yamada
Electronic Theses and Dissertations
This comparative analysis, focusing on the 150 highest-frequency phrasal verbs in the phrasal verb pedagogical list (Garnier and Schmitt, 2015), highlights the limited occurrence across English language textbooks for Japanese junior high school. The spoken and written data of Japanese learners of English (i.e., NICT-JLE and NICE) shows considerable differences in the usage patterns of phrasal verbs compared to native English speakers. These results indicated that Japanese learners’ underdeveloped productive knowledge of phrasal verbs could cause intelligibility problems with native speakers especially in oral communication. In order to overcome the semantic and phonological complexity of phrasal verbs, and to break …
A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do
A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do
Electronic Theses and Dissertations
The Heisenberg Hamiltonian is the prototype model for quantum magnetism. The Hamilto- nian includes exchange couplings between vector spins, which are the intrinsic magnetic moments of localized electrons. The classical energy between any pair of interacting spins can be minimized by aligning them parallel (ferromagnetic case) or antiparallel (antiferromagnetic), depending on the sign of the coupling. But quantum fluctuations play a key role, and a full quantum mechanical treatment of the many-body system is generally required. Finding the exact ground-state energy and wave function of isotropic antiferromagnetic (AFM) systems for an arbitrary spin-S and lattice morphology is still a challenging …
Dynamics For Discretized Gravity In The Causal Set Approach, Benjamin Pilgrim
Dynamics For Discretized Gravity In The Causal Set Approach, Benjamin Pilgrim
Electronic Theses and Dissertations
Causal set theory is an approach to quantum gravity which replaces the continuous spacetime manifold with a discrete set of points and a partial order. In this work, I will focus on causal sets embeddable in two-dimensional manifolds, and define an action based on chains which in the continuum limit replicates the Einstein-Hilbert action; furthermore, I will propose a variational principle based on this action and numerically show it can distinguish nonflat manifoldlike causal sets from the most common type of nonmanifoldlike causal sets. I will then supplement this action with a boundary term similar to the Gibbons-Hawking-York boundary term …
Interictal Avoidance Of Sensory Stimuli Among Individuals With Migraine, Daniel Rogers
Interictal Avoidance Of Sensory Stimuli Among Individuals With Migraine, Daniel Rogers
Electronic Theses and Dissertations
Migraine is the most debilitating neurological disorder worldwide and is associated with high economic and psychological costs. Common behavioral strategies for coping with migraine include avoidance of stimuli believed to precipitate an attack, though literature suggests that avoidance behaviors may serve to exacerbate migraine-symptoms and increase disability. Although the incorporation of trigger avoidance in modern conceptualizations of headache-related disability represents a more comprehensive understanding of disability occurring outside of migraine attacks (interictally), extant literature has emphasized trigger avoidance to the exclusion of other factors. Learning principles suggest stimuli that exacerbate migraine may take on similar eliciting properties as pain and …
