The Effect Of Heat Treatment And Chemical Treatment On Natural Fibre To The Durability Of Wood Plastic Composites – A Review, Nuratiqah Asyiqin Mohd Nasharudin, Nur Fatihah Sulaiman, Nurul Aziemah Mohammad, Wan Nor Raihan Wan Jaafar, Falah Abu Dr., Siti Norasmah Surip

Journal of Materials Exploration and Findings

The application of WPC is not only limited to indoor applications but has been extended to exterior applications where properties of WPC could compromise during service life. WPC was derived from wood fiber of various sizes to reinforce polymers. Wood fiber has the advantage of a cheaper price, being abundantly available, and ease of processing, however, the critical factor is its hydrophilic nature, where moisture absorption is likely to occur. Thus, treatments for reducing the hydrophilicity of wood fibers are applied. By treatment of wood fiber, the surface impurities were removed, leaving the roughened surface of fibers, thus providing a …

Neural Mechanisms Of Resiliency And Susceptibility After Repeated Social Defeat, Christy R. Wayne

LSU Doctoral Dissertations

Social defeat is a powerful experience leading to drastic changes in physiology and behavior, many of which are negative. For example, repeated social defeat in vertebrates results in reduced reproductive success, sickness, and behavioral abnormalities that threaten individual survival and species persistence. However, little is known about what neural mechanisms are involved in determining whether an individual is resilient or susceptible to repeated social defeat stress. I used a resident-intruder experiment in the African cichlid fish, Astatotilapia burtoni, to create and investigate the behavior and neural correlates of these two opposing groups. Resilient fish used both searching and freezing behaviors …

The Effects Of Ketones On Brain Metabolism And Cognition, Erin Reiko Saito

Theses and Dissertations

The brain is one of the most energetically demanding organs within the human body and is cognitively susceptible to energetic deficits such that the rise in obesity, insulin resistance, and Alzheimer’s disease in recent decades pose a substantial threat to cognitive longevity. The therapeutic efficacy of ketones are well-established in epilepsy and are currently being applied to other disease states. Alzheimer’s disease is characterized by impairments in brain glucose uptake and metabolism in regions relevant to learning, memory, and cognition that progress with the disease. While brain glucose uptake is impaired, ketone uptake is unaltered, potentially enabling ketones to fuel …

How Antitrust Failed Workers By Eric A. Posner, Maria Arabella M. Robles

Osgoode Hall Law Journal

IN RECENT YEARS, GROWING ECONOMIC INEQUALITY and anxieties about market power, monopolization, and other such concerns have rejuvenated competition and antitrust law and policy. It is well known that antitrust enhances competition by addressing issues of monopolization, price-fixing arrangements, and cartels, among other anticompetitive practices in markets. This allows dynamic competition to flourish in markets and ensures that consumers are provided with competitive prices and product choices. Although the negative impacts of market concentration are frequently recognized in the context of product markets, its impact on labour markets and the workers therein have largely been unexplored until recently. Professor Eric …

Department of Medicine Faculty Papers

BACKGROUND: Over the past decade, the prevalence of food insecurity declined in the United States but curiously climbed in Philadelphia, Pennsylvania, a sizable metropolitan area where many households experience food insecurity and are dependent on programs like SNAP. Therefore, we aimed to determine the burden of food insecurity among populations near Philadelphia Federally Qualified Health Center (FQHC) clinic sites.

METHODS: This cross-sectional study was conducted in North Philadelphia, a populous and impoverished section of Philadelphia with many zip codes reporting 30-45% or more of the population below the federal poverty line. Students and clinicians affiliated with a local FQHC conducted …

Leptopilina Heterotoma Responds To A Change In Host Species With Specific Altered Protein Expression, Dakota Fuss

Theses and Dissertations

Leptopilina heterotoma is a generalist endoparasitoid wasp that parasitizes Drosophila spp. worldwide. When L. heterotoma oviposits within the prey larvae it also injects venom to suppress the melanotic encapsulation immune response of the host. Without the venom to protect the egg(s) from host immunity, the parasitism would result in failure. L. heterotoma venom is composed of proteins, non-protein compounds, and virus-like particles (VLPs), of which proteins make up the majority of the venom and are the main determining factor conferring venom function (Goecks et al. 2013, Heavner et al. 2013, Moreau and Asgari 2015, Small et al. 2012). Previous studies …

Unmasking Structural Racism In U.S. Medical Education: Advancing Equity For Underrepresented Medical Students, Daryl O. Traylor, Eboni E. Anderson, Destiney Kirby, Asia Nichole Hodges, Brianna Clark, Stephen Sinatra Jr.

Journal of Social, Behavioral, and Health Sciences

The COVID pandemic cast a harsh light on the structural and systemic health inequalities that exist in American society and in U.S. medical education. Black and Brown communities were disproportionately affected, and the pandemic highlighted the need for a diverse physician and healthcare workforce. Both the lack of equitable, high-quality healthcare in underrepresented communities and the obstacles that students who are underrepresented in medicine (URiM) experience in medical school are direct consequences of the structural racism that flourishes in U.S. medical schools and healthcare institutions. In this article, we explain structural racism and how it has manifested itself in medical …

A Critical Perspective Over Whether And How To Acknowledge The Use Of Artificial Intelligence (Ai) In Qualitative Studies, Prokopis Christou

The Qualitative Report

There has been a rise in scepticism regarding the use of Artificial Intelligence (AI) in qualitative research tasks such as critical reviews, conceptualization, thematic and content analysis, and potentially theory development. Concerns have been raised over the possibility that researchers intentionally avoid discussing or even mentioning the use of AI in their studies for a variety of reasons, including the "fear" of criticism and rejection of their papers. The purpose of this paper, which is guided by critical perspective principles, is to examine the controversy surrounding the appropriate recognition of AI in theoretical discussions and qualitative research, including conceptual, critical …

The Mif Promoter Snp Rs755622 Is Associated With Immune Activation In Glioblastoma, Manmeet Ahluwalia

All Publications

tratumoral heterogeneity is a defining hallmark of glioblastoma, driving drug resistance and ultimately recurrence. Many somatic drivers of microenvironmental change have been shown to affect this heterogeneity and, ultimately, the treatment response. However, little is known about how germline mutations affect the tumoral microenvironment. Here, we find that the single-nucleotide polymorphism (SNP) rs755622 in the promoter of the cytokine macrophage migration inhibitory factor (MIF) is associated with increased leukocyte infiltration in glioblastoma. Furthermore, we identified an association between rs755622 and lactotransferrin expression, which could also be used as a biomarker for immune-infiltrated tumors. These findings demonstrate that a germline SNP …

Biological Formation Of Ethylene, Robert P. Hausinger, Simahudeen Bathir Jaber Sathik Rifayee, Midhun George Thomas, Shramana Chatterjee, Jian Hu, Christo Christov

Michigan Tech Publications

This review summarizes the structures, biochemical properties, and mechanisms of two major biological sources of ethylene, the ethylene-forming enzyme (EFE) and 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase (ACCO). EFE is found in selected bacteria and fungi where it catalyzes two reactions: (1) the oxygen-dependent conversion of 2-oxoglutarate (2OG) to ethylene plus three molecules of CO2/bicarbonate and (2) the oxidative decarboxylation of 2OG while transforming l-arginine to guanidine and l-Δ1-pyrroline-5-carboxylic acid. ACCO is present in plants where it makes the plant hormone by transforming ACC, O2, and an external reductant to ethylene, HCN, CO2, and water. Despite catalyzing distinct chemical reactions, EFE and …

Myc Regulates Csf1 Expression Via Microrna 17/20a To Modulate Tumor-Associated Macrophages In Osteosarcoma, Ryan Shuck, Atreyi Dasgupta, Nino Rainusso, Cristian Coarfa, Jason T Yustein

Faculty, Staff and Students Publications

Osteosarcoma (OS) is the most common primary bone tumor of childhood. Approximately 20%-30% of OSs carry amplification of chromosome 8q24, which harbors the oncogene c-MYC and correlates with a poor prognosis. To understand the mechanisms that underlie the ability of MYC to alter both the tumor and its surrounding tumor microenvironment (TME), we generated and molecularly characterized an osteoblast-specific Cre-Lox-Stop-Lox-c-MycT58A p53fl/+ knockin genetically engineered mouse model (GEMM). Phenotypically, the Myc-knockin GEMM had rapid tumor development with a high incidence of metastasis. MYC-dependent gene signatures in our murine model demonstrated significant homology to the human hyperactivated MYC OS. We established that …

The Essential Work Of Fracture In Peridynamics, Christer Stenström, Kjell Eriksson, Florin Bobaru, Stefan Golling, Pär Jonsén

Department of Mechanical and Materials Engineering: Faculty Publications

In this work, the essential work of fracture (EWF) method is introduced for a peridynamic (PD) material model to characterize fracture toughness of ductile materials. First, an analytical derivation for the path-independence of the PD J -integral is provided. Thereafter, the classical J -integral and PD J-integral are computed on a number of analytical crack problems, for subsequent investigation on how it performs under large scale yielding of thin sheets. To represent a highly nonlinear elastic behavior, a new adaptive bond stiffness calibration and a modified bonddamage model with gradual softening are proposed. The model is employed for two …

Effect Of Internal Curing And Shrinkage-Mitigating Materials On Microstructural Characteristics Of Fiber-Reinforced Mortar, Kamran Aghaee, Kamal Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Internal curing (IC) and other shrinkage mitigating materials are employed to reduce shrinkage and risk of cracking. This study investigates the efficiency of individual versus combined use of IC and shrinkage mitigating materials on key characteristics of fiber-reinforced mortar (FRM). The investigated mixtures include a 25% pre-saturated lightweight sand (LWS) that is added individually and combined with 10% CaO-based expansive agent (EA) and 2% shrinkage reducing admixture (SRA). This elucidates the synergistic effect of high content IC and EA/SRA on macro- and micro-mechanical characteristics of FRM, especially at the interface of the matrix with fibers. Mechanical properties, microstructural characteristics, and …

Thermoplastic Kilnforms: Extending Glass Kilnforming Techniques To Thermoplastic Materials Using Ontology-Driven Design, Mohammad Abu Nasir Rakib, Jeremy Scidmore, Justin Ginsberg, Cesar Torres

Association of Computing Machinery Open Access Agreement Publications-Archive

The ecology of thermoplastic materials is rapidly evolving, enabling an exciting landscape of functional, aesthetic, and interactive forms. Despite their utility in fused flament fabrication (FFF), an even larger and untapped design space exists for thermoplastics. In this work, we introduce a design method that leverages similarities with a more mature medium (glass) to guide a material-centered exploration of a new medium (thermoplastics). Through a collaboration between domain experts in thermoplastics and glass, we synthesized an ontology of kilnforming techniques and developed an annotated portfolio of thermoplastic kilnforms that capture generative design directions for altering the phenomenological qualities of plastic, …

Potential Biomarker Of Brain Response To Opioid Antagonism In Adolescents With Eating Disorders: A Pilot Study., Stephani L. Stancil, Hung-Wen Yeh, Morgan G. Brucks, Amanda S. Bruce, Michaela Voss, Susan Abdel-Rahman, William M. Brooks, Laura E. Martin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Eating Disorders (ED) affect up to 5% of youth and are associated with reward system alterations and compulsive behaviors. Naltrexone, an opioid antagonist, is used to treat ED behaviors such as binge eating and/or purging. The presumed mechanism of action is blockade of reward activation; however, not all patients respond, and the optimal dose is unknown. Developing a tool to detect objective drug response in the brain will facilitate drug development and therapeutic optimization. This pilot study evaluated neuroimaging as a pharmacodynamic biomarker of opioid antagonism in adolescents with ED.

METHODS: Youth aged 13-21 with binge/purge ED completed functional …
