An Additive Incorporated Non-Nucleophilic Electrolyte For Stable Magnesium Ion Batteries, Mao-Ling Xie, Jun Wang, Chen-Ji Hu, Lei Zheng, Hua-Bin Kong, Yan-Bin Shen, Hong-Wei Chen, Li-Wei Chen

Journal of Electrochemistry

Non-nucleophilic electrolytes are promising next-generation highly stable electrolytes for magnesium-ion batteries (MIBs). However, a passivation layer on Mg metal anode usually blocks Mg²⁺ diffusion, leading to poor reaction kinetics and low Coulombic efficiency of the Mg plating/stripping in these electrolytes. Here we explore the utilization of phenyl disulfide (PDF) as a film-forming additive for non-nucleophilic electrolytes to regulate the interfacial chemistry on Mg metal anode. Phenyl-thiolate generated from the PDF additive was found to suppress the unfavorable surface blocking layer, resulted in a high Coulombic efficiency of up to 99.5% for the Mg plating/stripping process as well as a …

Eating Real Mexican: Identity, Authenticity, Americanization, Health, And Food Culture In The United States After 1900, Alexandra H. Ibarra

Dissertations and Theses

This thesis examines the connection between Mexican food and identity in the early to mid-twentieth century (1900-1950). Anglo-Americans created evolving racial/ethnic stereotypes during a period of intense Mexican immigration and nativism that used descriptions of food, hygiene habits, and health to reinforce boundaries of whiteness and citizenship.

By examining Americanization teaching manuals, food articles, as well as personal and corporate cookbooks, I seek to understand how Americanizers and other food writers used food to point to emphasize, unhygienic habits, excess use of spice and grease, as well as the "questionable" nature of immigrate food culture to separate them from Anglo-Americans. …

Small-Molecule Ras Inhibitors As Anticancer Agents: Discovery, Development, And Mechanistic Studies, Shaila A. Shetu, Debasish Bandyopadhyay

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

Mutations of RAS oncogenes are responsible for about 30% of all human cancer types, including pancreatic, lung, and colorectal cancers. While KRAS1 is a pseudogene, mutation of KRAS2 (commonly known as KRAS oncogene) is directly or indirectly associated with human cancers. Among the RAS family, KRAS is the most abundant oncogene related to uncontrolled cellular proliferation to generate solid tumors in many types of cancer such as pancreatic carcinoma (over 80%), colon carcinoma (40–50%), lung carcinoma (30–50%), and other types of cancer. Once described as ‘undruggable’, RAS proteins have become ‘druggable’, at least to a certain extent, due to the …

High-frequency accelerometer recording of key predatory behaviors in vipers: validation and case study with Timber Rattlesnakes (Crotalus horridus)

Morgan Thompson, Richard H. Adams, Anna F. Tipton, and Dominic L. DeSantis

Tri-axial accelerometers (ACTs) are becoming increasingly common in studies of animal behavior wherein direct observation of subjects in nature is constrained or impossible. ACTs are small (< 1 g) piezo-electric (spring-like) sensors that measure three-dimensional acceleration (upward, downward, and side-to-side) derived from subject motion. When leveraged with advanced machine learning techniques, these data can enable precise automated classification of a wide range of movement-mediated behaviors. Until recently, ACTs were largely reserved for larger-bodied organisms or those most amenable to the temporary external attachment of devices. Ongoing ACT miniaturization has now expanded the breadth of organisms amenable to these methods. This project aims to expand on a recently developed framework for ACT monitoring in wild-ranging snakes, a group that has been mostly overlooked in biologging applications. We are currently conducting extensive captive validation trials for robust model training and testing to enable classification of predatory behaviors, including striking and ingestion of prey items, in Timber Rattlesnakes (Crotalus horridus). Following captive validation, we will translate this method to the field with a population of C. horridus in the lower Piedmont of middle Georgia to evaluate the efficacy of externally attached ACTs for remote and continuous monitoring of …

The Method Of Critical Phenomenology: Simone De Beauvoir As A Phenomenologist., Johanna K. Oksala

Philosophy: Faculty Publications and Other Works

The paper aims to contribute to the ongoing conversation on critical phenomenology with reflections on its method. The key argument is that critical phenomenology should be understood as a form of historico-transcendental inquiry and therefore it cannot forgo the phenomenological reduction. Rather, this methodological step should be centered in critical phenomenology, and appropriated in problematized and rethought forms. The methodological assessment of critical phenomenology has implications also for how we read its canon. The paper shows that while Simone de Beauvoir did not adopt the phenomenological reduction in its full Husserlian meaning, her analyses of experience did not remain on …

Phenotypic Variability In Ipsc-Induced Cardiomyocytes And Cardiac Fibroblasts Carrying Diverse Lmna Mutations, Jiajia Yang

USF Tampa Graduate Theses and Dissertations

Mutations in the LMNA gene (encoding lamin A/C) are the second most common cause of familial arrhythmogenic cardiomyopathy. Diverse LMNA variants in cardiomyocytes have been associated with cardiac phenotypes. Moreover, cardiac fibroblasts make up a large fraction of the myocardium's non-myocyte component, intrinsically linked to extracellular matrix synthesis and turnover as well as secreting large amounts of bioactive metabolites. However, our understanding of how different mutation sites and the non-myocyte niche mediate cardiomyocyte function is limited. To fill this gap, in this thesis I investigated the hypothesis that variable LMNA mutations have significant effects on the genetic, structure and electrophysiological …
