Field-Directed Fabrication Of Hierarchical Structures Toward Electrochemical Applications, Anirudh Balram Aug 2017

Field-Directed Fabrication Of Hierarchical Structures Toward Electrochemical Applications, Anirudh Balram

Mechanical and Aerospace Engineering Dissertations - Archive

The ubiquity of hierarchical structures in nature indicates an inherent advantage to having morphological features comprised of multiple length scales. Such structures help maximize interfacial surface area, allowing for efficient chemical reactions and mass transport despite volumetric constraints. In electrochemical applications such as batteries, supercapacitors, electrolysis, fuel cells, catalysis etc. there is a similar necessity to maximize electrochemically active surface area to facilitate facile charge and mass transport. Inspired by examples in nature, this work seeks to develop scalable fabrication techniques to obtain hierarchically structured high-performance electrodes for electrochemical applications, with a focus on energy applications. Particular emphasis was laid …

Metabolic, Hemodynamic And Electrophysiological Effects Of Transcranial Photobiomodulation (Tpbm) On The Human Brain, Xinlong Wang Aug 2017

Metabolic, Hemodynamic And Electrophysiological Effects Of Transcranial Photobiomodulation (Tpbm) On The Human Brain, Xinlong Wang

Bioengineering Dissertations - Archive

Photobiomodulation (PBM) refers to the use of red-to-near-infrared light to stimulate cellular functions for physiological or clinical benefits. Transcranial photobiomodulation (tPBM) is a noninvasive form of cerebral photobiomodulation that has been observed with various improvements in human cognitive functions. The mechanism of tPBM is assumed to rely on photon absorption by cytochrome c oxidase (CCO), the terminal enzyme in the mitochondrial respiratory chain that catalyzes the reduction of oxygen for energy metabolism. However, few studies have objectively investigated hemodynamic, metabolic and electrophysiological response of the human brain to tPBM. To address this gap, my dissertation research has focused on objective …

Naturally-Derived Extracellular Matrix Materials For Meniscus Repair And Regeneration, Jinglei Wu Aug 2017

Naturally-Derived Extracellular Matrix Materials For Meniscus Repair And Regeneration, Jinglei Wu

Bioengineering Dissertations - Archive

Human meniscus plays critical roles in a knee joint by transmitting weight-bearing force, absorbing shock, and stabilizing the knee joint capsule. Meniscal injuries are mainly caused by sports-related activities and age-related degeneration, which significantly reduce the life quality of patients. The injured meniscus has a very limited self-healing capability due to its poorly vascularized nature, specifically in the inner area. Surgical interventions are required to treat the injured meniscus, but the current treatments are not satisfactory because the post-surgery complications are frequently observed. Therefore, tissue regeneration approaches are developed to repair and functionally restore injured menisci. In this thesis, we …

Growth And Stress Response Mechanisms Underlying Post-Feeding Organ Regenerative Growth In Snakes, Audra Leann Andrew Aug 2017

Growth And Stress Response Mechanisms Underlying Post-Feeding Organ Regenerative Growth In Snakes, Audra Leann Andrew

Biology Dissertations - Archive

Snakes represent an emerging model in biological research and provide a valuable system for studying multiple extreme phenotypes unparallel to those seen in mammals. Recently, snakes have become increasingly used in studies of extreme organ regenerative growth due to the ability of some species to rapidly and reversibly upregulate organ form and function upon feeding. The predominant model used to study this feeding response has been the Burmese python (Python molurus bivittatus) because of the particulalry extreme nature of this post-feeding response in this species. Specifically, the wet masses of major organs increase by 50-100% within just 48 hours post-feeding …

The Motivational Pull Of Video Game Feedback, Rules, And Social Interaction: Another Self-Determination Theory Approach, Ryan Rogers Aug 2017

The Motivational Pull Of Video Game Feedback, Rules, And Social Interaction: Another Self-Determination Theory Approach, Ryan Rogers

Scholarship and Professional Work - Communication

This paper argues that most video game enjoyment can be understood in terms of the type of feedback used, the rules set out by the game and the social elements of the game - concepts that have been identified as critical to video games. Self-determination theory (SDT) is used as a lens for understanding the mechanism by which these traits might lead to enjoyment. Specifically, the argument is that feedback, rules, and social elements of games will fulfill the dimensions of SDT - competence autonomy, and relatedness. Then, the dimensions of SDT will predict enjoyment. Participants were presented with a …

Effects Of Early Adolescent Exposure To D-Amphetamine In A Rodent Model Of Nicotine Reward, Eric Louis Harvey Aug 2017

Effects Of Early Adolescent Exposure To D-Amphetamine In A Rodent Model Of Nicotine Reward, Eric Louis Harvey

Dissertations

Previous studies with rodents have found that adolescent exposure to psychoactive drugs can alter neurophysiology and produce behavioral effects that persist into adulthood. While several studies have examined the effects of adolescent exposure to nicotine on the subsequent rewarding value of various drugs of abuse in adulthood, to date, no known studies have examined the converse of this relationship. d-Amphetamine (i.e., dextroamphetamine, ProCentra®) is a potent psychostimulant that is commonly used in the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in adolescents. The present study assessed the effects of adolescent exposure to d-amphetamine on the rewarding value of nicotine in …

Novel Animal Models Of Chronic Stress And ‘Chemobrain’: Behavioral, Physiological, And Molecular Biomarkers, Moriah L. Jacobson Aug 2017

Novel Animal Models Of Chronic Stress And ‘Chemobrain’: Behavioral, Physiological, And Molecular Biomarkers, Moriah L. Jacobson

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Chronic stress underlies several disorders, including post-traumatic stress disorder (PTSD), and complicates patient responses to life threatening diseases such as cancer, making this condition an important public health concern. The gene regulatory network integrates several signals, yielding a particular pattern of gene expression. Changes in global gene expression (transcriptome) may provide a reliable measure of the intensity/dosage of stress or drug an animal has experienced as well as distinguish different types of stress or drug experiences. Our studies used RNA sequencing (RNAseq) to analyze the transcriptome in several tissues from rat models of chronic stress and chemotherapy-induced cognitive impairment (CICI …

Role And Regulation Of Sphingomyelin Synthase 1 In Leukemia, Sitapriya Moorthi Aug 2017

Role And Regulation Of Sphingomyelin Synthase 1 In Leukemia, Sitapriya Moorthi

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Sphingomyelin synthase (SMS1 and SMS2) enzymes constitute a class of transferases, belonging to the sphingolipid pathway and they catalyze the synthesis of sphingomyelin (SM). The role of sphingolipids has transformed, from being vital components of cellular membranes to mediators of various biological processes, such as proliferation, regulation of the cell cycle and differentiation. SMS catalyzes the transfer of the phosphorylcholine moiety from phosphatidylcholine to ceramide (Cer), generating SM and diacylglycerol (DAG). The role of SMS in cancer stems from its ability to regulate the levels of two bioactive lipids, Cer (mediator of anti-proliferative effects) and DAG (a mitogenic lipid), …

Transnational Images In A Global Frame: Film Festivals And Taiwan Cinema Through The Lens Of Hou Hsiao-Hsien And Tsai Ming-Liang, Peijen Beth Tsai

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

This dissertation examines the geopolitical and cultural dynamics between European and Taiwan cinema. I explore how art house cinema were circulated and received at major European festivals—Berlin, Cannes, and Venice—to question the role that film festivals play in influencing new cinematic styles for local, regional, and global consumption. Before Taiwan New Cinema became world renowned, films from Taiwan, despite sporadic forays into international festivals, had hitherto been prescribed as coming from a non-national nation (Chinese Taipei), or a nation without nationality (Taiwan, Province of China). If Taiwan cinema’s success in the film festival circuits is due to its proliferation of …

Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content, And Palatability In Simulated Retail Display, Fred W. Pohlman Ii

Animal Science Undergraduate Honors Theses

Nutritional concerns and attempts to limit fat in the diet over the past decades have impacted the protein market, decreasing red meat consumption as well as prompting the advent of lean and extra lean ground beef. Such lean blends of ground beef may suffer in palatability, however, resulting in less satisfied consumers turning to other protein sources. While consumers are demanding lean ground beef, fatter blends may be more palatable. This study seeks to bridge the gap between perceived health and palatability by evaluating preferred fat content and instrumental color characteristics between labeled and unlabeled packages of ground beef in …

Epigenetic Mechanism Of Regulation Of Hox Genes And Neurotransmitters Via Hormones And Lncrna, Paromita Deb

Chemistry & Biochemistry Dissertations - Archive

Endocrine disrupting chemicals (EDCs) are classes of environmental contaminants whose exposure even at very low concentrations interfere with normal endocrine signaling and induce many adverse health effects including increased risk of birth defects, diabetes, obesity, abnormal reproduction, and cancer. EDC exposure alters the epigenetic programming of cells resulting in altered gene expression and regulation and cell signaling. These EDCs include bisphenol-A (BPA), diethylstilbesterol (DES), polychlorinated biphenyl (PCB), phthalates, phytoestrogens, methoxychlor, fungicides, insecticide, herbicide, and some heavy metals. As a part of my work, I have investigated epigenetic impacts of EDCs on HOX (homeobox containing genes) genes, which are critical players …

Biology Dissertations - Archive

Long interspersed nucleotide elements (LINEs) are major drivers of genomic landscaping events in many eukaryotic genomes. LINEs encode a multifunctional protein that binds to their own mRNA, recognize and cleave target DNA, and performs target-primed reverse transcription (TPRT). R2 element from Bombyx mori (R2Bm) has served as an important experimental system for the biochemical understanding of the structure, function, and integration of LINEs. First-strand target site cleavage and TPRT in the current model of integration have been well understood both in vitro (using R2Bm) and in vivo (using LINE-1 elements); however, interpretation of factors involved in second-strand cleavage and second- …

Impacts Of Landscape And Past Climate On Patterns Of Hybridization And Genetic Diversity In Plestiodon Tetragrammus And P. Multivirgatus, Matthew Moseley Aug 2017

Impacts Of Landscape And Past Climate On Patterns Of Hybridization And Genetic Diversity In Plestiodon Tetragrammus And P. Multivirgatus, Matthew Moseley

Biology Dissertations - Archive

Past hybridization plays an important role in evolution of taxa. We use multiple phylogenetic approaches including single gene sequencing and high-through put sequencing to address the effects of past hybridization in the four-lined skinks, P. tetragrammus, and the variable skink, P. multivirgatus. We show that mitochondrial genes have been introgressed between P. multivirgatus and P. t. brevilineatus. We also show that this introgression has lead to decreased genetic diversity in these lineages. We use species distribution models to show that P. multivirgatus and P. t. brevilineatus shared a large portion of their ranges in the last glacial maximum allowing for …

From "Struggling" To "Example": How Cross-Age Tutoring Impacts Latina Adolescents' Reader Identities, Dustin H. Drake

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Educators and policy makers have shown a consistent concern over the achievement gap. In academic assessments, Latino students have demonstrated lower achievement than their peers, particularly in reading scores. Many researchers attribute the existence of the achievement gap to a school system that ignores Latino culture or perpetuates struggles in Latino students’ reading by being culturally insensitive. Multiple theorists suggest that school systems that better understand Latino identities will be better at instructing Latino students. Many programs, including Latinos in Action, have been implemented in attempts to close this gap. The Latinos in Action program utilizes Latino adolescents as peer …
