More selective inhibition of AChE than BChE was observed for these compounds. For AChE, CoPc was identified as the most potent inhibitor (IC50 = 14.81 nM), whereas for BChE, InPc was …

Templating Effect Of Neutral Dithiane Ligands On The Self-Assembly Of Cationic Au(I)-Phosphine Units, Farzane Osanlou, Abdollah Neshat, Mohammad Reza Yousefshahi, Vaclav Eigner, Michal Dusek, Shahram Seidi

Turkish Journal of Chemistry

The interactions between the dinuclear Au(I) precursor (dppm)Au2Cl2 and neutral sulfur-containing dithianes (specifically 1,3- and 1,4-dithiane) were examined in the presence of NH₄PF₆. Although these sulfur-based ligands were initially employed to facilitate the formation of mixed phosphine/sulfur Au(I) complexes, single-crystal X-ray diffraction analysis revealed the unexpected generation of multinuclear Au(I) assemblies exclusively coordinated by phosphine ligands. When 1,3-dithiane was present, a trinuclear Au(I) complex was isolated, characterized by a central four-coordinate Au(I) center exhibiting a distorted see-saw geometry, flanked by two terminal Au(I) centers with T-shaped coordination environments. Importantly, the dithiane ligand did not coordinate directly to the gold centers …

Influence Of Precursor Synthesis Temperature And Hydrothermal Alkaline Medium On Agglomeration And Crystal Phase Of Barium Titanate Nanoparticles, Murat Özen

Turkish Journal of Chemistry

Phase‑pure, cube‑like barium titanate (BaTiO3) nanoparticles were synthesized via hydrothermal treatment of a single‑source barium-titanium peroxo-hydroxide precursor. Precursor solutions prepared at room temperature, 0 °C, and –10 °C with various storage times exhibited Ba/Ti molar ratios ranging from 0.66 to 1.05 as determined by X-ray fluorescence. Cooling the precursor solution to –10 °C effectively suppressed the polymerization of Ti-O-Ti, yielding near‑ideal stoichiometry and finer precursor particles. Subsequent hydrothermal processing in NH4OH, KOH, and NaOH (0.5–10 M, 100–200 °C) revealed the strong dependence of agglomeration and morphology on the alkaline medium. While NH4OH and KOH resulted in severe agglomeration and the …

The results indicated that …

Church, Mosque, And State: The Impacts Of Sectarian Politics On Lebanon’S Democracy, Tonia Attie

Departmental Honors & Graduate Capstone Projects

As Lebanon seeks to reform multiple sectors of the country, it is crucial to understand how its consociational government, centered on religious identities, interacts with its citizens. Electoral accountability is the process by which an electorate holds politicians liable for their actions while in office. While previous studies, such as Vincent Hutchings’ “Public Opinion and Democratic Accountability,” have shown how electoral accountability functions within traditional party systems based on political ideology, there is little research on how accountability mechanisms operate in confessional party systems based on religion. This paper posits that within countries with confessional systems, voters are less able …

Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes

Theses and Dissertations

School principals face increasing complexity as they navigate instructional leadership, organizational change, and the emotional demands of supporting staff and students. Traditional professional development--often episodic and compliance-driven--has proven insufficient for helping principals translate knowledge into practice. This qualitative phenomenological study examined how 20 elementary principals in a large intermountain district experienced a dual-coach, team-based leadership coaching model and how coaching influenced their leadership practices and well-being. Semi-structured interviews and iterative thematic analysis revealed that coaching shaped three core areas of leadership practice: gaining clarity and direction, prioritizing instructional and organizational goals, and strengthening collaboration within school leadership teams. Principals also …

Self-Concept Clarity And Relationship Satisfaction: The Mediating Role Of Approach And Avoidance Motives For Sacrifice Among Heterosexual Couples, Hannah F. Hatch

Theses and Dissertations

While individuals often engage in relational sacrifice to promote positive outcomes like connection (approach motives), they may also sacrifice for a partner to avoid negative outcomes like conflict (avoidance motives). These distinct motives for sacrifice have been repeatedly linked with divergent couple outcomes, yet little is known about the personal and relational factors which shape them. The current study addressed this gap using dyadic data from 289 mixed-gender couples to examine how self-concept clarity (SCC) predicted changes in relationship satisfaction via approach and avoidance motives for sacrifice. Participants represented diverse ethnic and sociodemographic backgrounds across all demographic regions of the …

The Lookahead Transformer, Justin P. Olcott

Theses and Dissertations

Large Language Models (LLMs) are transformer models that generate text autoregressively in two stages: prefill and decode. The prefill stage processes all input tokens in parallel and caches them into the KV cache. The decode stage uses the KV cache, processes a single token at a time, and is generally memory-bandwidth constrained. Each decode step generates a token probability distribution, samples from it, appends the token to the cache, and repeats. This left-to-right, one-at-a-time generation paradigm has proven effective for language modeling in many domains; however, it also has limitations such as token permanence, constant compute per token generation, constant …

Ergonomic And Material Flow Improvements For A Medical Device Assembly Line, Matthew Kobus

Honors Theses

This project evaluated material handling inefficiencies and ergonomic concerns within Stryker’s Neptune medical device assembly line. Two primary issues were identified: lack of a standardized part-location system in the supermarket and excessive operator travel between subassembly and main assembly. These issues resulted in search waste, motion waste, lost production time, and increased ergonomic strain.

To address the labeling issue, a standardized bin labeling system was developed and tested. A time study comparing labeled and unlabeled conditions showed that average retrieval time decreased from approximately 120 seconds to 22 seconds, an 81% reduction. Statistical analysis confirmed that this improvement was significant …

​Functional Characterization Of Stmtpsl Terpene Synthase-Like Genes And Their Role In Pathogen Resistance In Selaginella Tamariscina, Zhijie He, Bo Bi

Turkish Journal of Agriculture and Forestry

The biological activity and function of microbial terpene synthase-like genes from Selaginella tamariscina (StMTPSL) were investigated using molecular and biochemical approaches. After isolating and amplifying StMTPSL genes (StMTPSL1-StMTPSL6), both native and site-directed mutant forms were expressed in tobacco via Agrobacterium-mediated transformation. The resulting transgenic plants had increased expression of StMTPSL genes, enhanced monoterpene production (as confirmed by GC-MS), and significantly improved resistance to Pseudomonas syringae infection compared to nontransgenic controls. These results show that StMTPSL genes are functionally active in plants and contribute to pathogen resistance through elevated terpene biosynthesis. This study provides new insights into the role of MTPSL …

The Right Of Nature: Lessons From Panama For Mangrove Protection In Miami, Jayson Fry

University of Miami Inter-American Law Review

Mangrove ecosystems are indispensable to climate resilience, yet traditional environmental governance has repeatedly failed to prevent their decline. This Note employs a comparative framework to examine Panama and Miami, two rapidly developing coastal regions facing parallel pressures of urbanization and sea-level rise, to demonstrate that mangrove loss persists not because law is absent, but because existing frameworks structurally authorize regulated degradation. Panama’s 2022 Rights of Nature Law, which grants ecosystems legal personhood and enforceable rights, represents a departure from anthropocentric environmental regulation. Its early judicial application in the Cobré Panamá mine case shows how rights-based protections can override extractive economic …
