Stereospecific Cross-Coupling Reactions Of Enantioenriched Secondary Alkyltricyclohexyltin Nucleophiles, Meruyert Binayeva 2024 The Graduate Center, City University of New York

Stereospecific Cross-Coupling Reactions Of Enantioenriched Secondary Alkyltricyclohexyltin Nucleophiles, Meruyert Binayeva

Dissertations, Theses, and Capstone Projects

Transition metal-catalyzed cross-coupling reactions have evolved into a remarkable instrument for the formation of new bonds, and have significantly impacted how we approach to access complex organic molecules. Palladium is currently one of the most popular elements for catalytic applications due to its ability to facilitate powerful carbon-carbon and carbon-heteroatom couplings. Traditional Pd-catalyzed cross-coupling reactions have primarily concentrated on C(sp2)-C(sp2) cross-couplings, yielding planar products. Considering the use of C(sp3) nucleophiles would offer a viable control of the three dimensional arrangement in molecules. Herein, the first chapter details the history and development of Pd-catalyzed Stille cross-coupling reactions. The use of configurationally …


Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems, Oluchuku Richie Ochonogor 2024 Columbus State University

Investigating Ammonium Toxicity In The Performance Of Recirculating Periphytic Algal Wastewater Treatment Systems, Oluchuku Richie Ochonogor

Theses and Dissertations

Freshwater nutrient enrichment from wastewater facilities and other sources can lead to freshwater eutrophication, a threat to global aquatic ecosystems. Mechanical and chemical ways to curb this threat are either too expensive or not sustainable, and thus, not feasible. Compared to mechanical and other methods, sustainable, inexpensive biological methods (for example, algal treatment systems) have therefore been developed for the removal of excess nutrients from wastewater. By design, secondary waste treatment facilities (WWTF) remove organics and solids and lower oxygen demanding substances; however, they may not remove enough nutrients to protect freshwater ecosystems in all cases. While algae-based biological methods …


Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia 2023 Brigham Young University

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Trees In Our City How A Tree And A Small Patch Of Dirt Inspired A Classroom, Zuleika Hines

Occasional Paper Series

As a new Director in a new school, I knew that I wanted the children to have a curiosity for nature. But to lead the children to a place of discovery, they would need the opportunity to observe, play, and engage in elements of nature that would support hands-on activities both in the classroom and outside. When the opportunity came for me to build my own early childhood program, I knew that I had a unique opportunity to incorporate elements of nature in the design of the classroom. But I wanted nature to be local and the trees of our …

On The Origins Of Life — Modelling The Initial Stages Of Complex Coacervate Droplet Formation, Yixuan Wu 2023 Western University, London, ON

On The Origins Of Life — Modelling The Initial Stages Of Complex Coacervate Droplet Formation, Yixuan Wu

Western Libraries Undergraduate Research Awards (WLURAs)

Coacervate droplets are considered a plausible model for protocells due to their spontaneous formation and ability to compartmentalize macromolecules such as nucleic acid and peptides. Although experimental studies have observed and synthesized coacervates under different laboratory conditions, little is known about their structure. Here we present atomistic molecular dynamic simulations of the interactions between water and oppositely charged proteins that cluster together in a salt-dependent process. Observing such liquid-liquid phase separation on an atomic level would serve as a model for the initial stages of complex coacervate formation. Molecular Dynamics was used to compute diagnostics of the structure at different …

Exploiting Vulnerabilities In The Ras-Rac Signaling Pathway For The Selective Targeting Of Pancreatic Cancer Cells, Neha Chaudhary 2023 University of Nebraska Medical Center

Exploiting Vulnerabilities In The Ras-Rac Signaling Pathway For The Selective Targeting Of Pancreatic Cancer Cells, Neha Chaudhary

Theses & Dissertations

Deregulation of the KRas (Kirsten rat sarcoma virus) GTPase is one of the early hallmarks of Pancreatic Cancer (PC). The most common genetic alteration found in PC are mutations in the KRas protein that block its ability to hydrolyze GTP to GDP and resulting in higher levels of GTP-bound KRas, its active form. Pancreatic tumors driven by oncogenic mutants of KRas tend to be addicted to the oncogene, to the extent that its repression leads to the induction of cell death. This addiction to the KRAS oncogene makes the KRas protein an ideal target for cancer therapy. However, the globular …


Generation Z’S Perceptions Of Hunting And Conservation Efforts In Arkansas, Hannah Ferguson 2023 University of Arkansas-Fayetteville

Generation Z’S Perceptions Of Hunting And Conservation Efforts In Arkansas, Hannah Ferguson

Graduate Theses and Dissertations

Hunting participation numbers have steadily declined since the 1980s and Generation Z is not engaging in hunting. Hunting is one of the most effective tools for managing wildlife populations and ensuring the success and local ecosystem conservation. Many wildlife stewardship institutions, such as Arkansas Game and Fish Commission in Arkansas, are funded by sales taxes imposed on firearms, ammo, and archery equipment. With a decline in hunting participation, it is imperative state-run wildlife stewardship organizations and other hunting institutions learn the best practices for communicating with younger generations. This study sought to understand Generation Z’s perceptions of hunting and conservation …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The impacts of science are felt across all socio-ecological levels, ranging from the individual to societal. In order to adapt or respond to scientific discoveries, novel technologies, or biomedical or environmental challenges, a fundamental understanding of science is necessary. However, antiscientific rhetoric, mistrust in science, and the dissemination of misinformation hinder the promotion of science as a necessary and beneficial component of our world. Scientists can promote scientific literacy by establishing dialogues with nonexperts, but they may find a lack of formal training as a barrier to public engagement. To address this, the American Society for Biochemistry and Molecular Biology …


Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer 2023 Southern Methodist University

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Extraction And Characterization Of Antifungal Compounds Produced By Lowbush Blueberry Plants In Response To Monilinia Vaccinii-Corymbosi Infection, Sophia Suriano 2023 University of Maine - Main

Extraction And Characterization Of Antifungal Compounds Produced By Lowbush Blueberry Plants In Response To Monilinia Vaccinii-Corymbosi Infection, Sophia Suriano

Honors College

Maine’s wild blueberries are a vital economic and ecological resource for growers, consumers, and researchers alike. Fungal diseases like Monilinia vacciniicorymbosi (MVC) reduce the yield of berries from infected plants by killing plant tissues and damaging fruit. Understanding what blueberry plants use to defend themselves against fungal pathogens can give a greater insight into increasing plant immunity as a whole. This project aims to better understand the wild blueberry antifungal defense response. I extracted bioactive compounds from the healthy leaves of low severity and high severity disease-affected plants and separated the molecules with thin layer chromatography (TLC). Aspergillus sp. acted …
