Transmission Patterns That Reduce Population Size Without Increasing Disease Prevalence: Masting And Chronic Wasting Disease In White-Tailed Deer, Virginia Kanzinger, Karen C. Abbott

Faculty Scholarship

How individuals use space and, thus, the rate and the nature of their interactions with others are shaped by their environment. Exogenous changes that alter aggregation patterns, such as resource pulses, can therefore have a significant impact on seemingly unrelated processes like disease spread. White-tailed deer (Odocoileus virginianus) aggregate in oak forests during mast events, and chronic wasting disease (CWD) transmission patterns vary with deer density, so we hypothesize a link between the masting cycle and CWD dynamics. We investigate various possible effects of masting on deer, including shifts to more frequency-dependent CWD transmission due to aggregation, as well as …

Theoretical Study On Electronic And Optoelectronic Properties Of Some C^N^N- And C^C^C-Chelated Iridium(Iii) Complexes For Oleds, Ayhan Üngördü

Turkish Journal of Chemistry

The electronic and optoelectronic properties of 8 C∧N∧N- and C∧C∧C-chelated Ir(III) complexes were investigated using density functional theory at the Becke-style 3-parameter Lee-Yang-Par and triple zeta plus polarization level. Based on reorganization energy calculations, complex 7 was identified as a promising ambipolar material, while complexes 1 and 2 had efficient hole transport properties. Complex 8 had low ionization potential and is therefore a strong candidate for hole transport applications. Complex 4 had high electron affinity and therefore has potential as an effective electron acceptor material. Photophysical analysis showed that all complexes had phosphorescent properties, with complexes 5 and 6 showing …

Optimizing Polyamide Thin-Film Composite Desalination Membranes: Simple And Performance-Effective Modification By Zwitterionic Monohydroxyl Monomer, Selda Erkoç İlter

Turkish Journal of Chemistry

A synthesized zwitterionic monohydroxyl monomer (ZHM) was used as an additive to incorporate zwitterionic sulfobetaine groups into the polyamide (PA) active layers of thin-film composite membranes. Incorporation of ZHM into the PA active layers was achieved through interfacial polymerization, involving the introduction of ZHM and m-phenylenediamine (MPD) into the aqueous phase, and the addition of trimesoyl chloride (TMC) to the hexane phase. The surfaces of the resulting reverse osmosis (RO) membranes were subjected to characterization through water contact angle (WCA) and field emission scanning electron microscopy (FESEM) analyses. The successful incorporation of ZHM into the active PA layers was confirmed …

To compare the enzyme responsiveness of MON, the reference periodic mesoporous organosilica (PMO) nanocarrier was also synthesized using BTSB only. The structural determinations of the synthesized organic compounds were carried out by 1H, 13C-NMR, FT-IR, and MS, while FT-IR, XRD, SEM, EDS, transmission electron microscopy (TEM), TGA, and N2 sorption analyses were used for the characterization of MON and …

Dielectric And Mechanical Properties Of Polyaniline-Grafted Sepiolite Loaded Pvc Nanocomposites, Asif Raza, Tariq Yasin, Muhammad Nadeem, Muhammad Arshad Farhan

Turkish Journal of Chemistry

Conducting polymers exhibit interesting dielectric properties due to their unique conjugated π-electron backbone. The objective of this study was to examine the dielectric properties of nanocomposites containing a conducting nanohybrid (NH) as a filler. Polyaniline was grafted onto sepiolite by in situ emulsion graft polymerization to synthesize a conducting NH. This NH was blended with poly(vinyl chloride) (PVC) using a melt blending technique. Nanocomposites with variable amounts of nanofiller were prepared and characterized. Fourier-transform infrared (FT-IR) spectra of the NH composites show strong interactions between their individual components. The addition of the nanofiller into PVC increased its thermomechanical properties. Dielectric …

Selective Extraction Of Scandium From Other Rare Earth Elements Using A Hydrophobic Protic Ionic Liquid Composed Of Decanoic Acid And Toa, Pius Dore Ola, Reo Nishioka, Yoshiro Tahara, Michiaki Matsumoto

Turkish Journal of Chemistry

Rare earth elements (REEs) are increasingly being used in advanced materials, but their extraction remains a major challenge. This is primarily due to their nearly identical ionic radii and similarity in chemical and physical properties. Therefore, this study aims to explore the use of a hydrophobic protic ionic liquid (PIL) composed of decanoic acid and trioctylamine (TOA) to selectively extract scandium (Sc) from other REEs using acid or salt as the extraction medium. In the acidic medium, the extraction efficiency of all tested REEs was inversely proportional to the acid concentration. Meanwhile, the extraction percentage of Sc was significantly higher …

The Professional And Occupational Identities Of Nicu Occupational Therapists, Lindsay M. Marquardt, Karen Park

Summer 2025 OTD Capstone Symposium

Occupational therapists in the neonatal intensive care unit (NICU) provide specialized care, including infant positioning, feeding, handling techniques, and anticipatory guidance. While the American Occupational Therapy Association has outlined the role, little research has explored how therapists perceive their own occupational and professional identities in this highly specialized setting. This study explored the perspectives of NICU occupational therapists to better understand how their roles and identities are shaped within the NICU environment. A mixed-methods descriptive design was used. Data was collected through an electronic survey including Likert-scale and open-ended questions, with optional 30-minute follow-up interviews. Snowball and convenience sampling were …

Addressing Psychosocial Barriers To Participation In People Experiencing Homelessness: An Occupational Therapy Workshop, Preston E. Bender

Student Capstone Papers

This capstone project addressed the critical gap in occupational therapy education and practice regarding the psychosocial needs of people experiencing homelessness. Despite the occupational therapy profession’s emphasis on holistic, person-centered care, many occupational therapy practitioners and occupational therapy students report feeling a lack of self-efficacy and preparedness to navigate the complex psychological, social, and systemic barriers that hinder occupational participation among this population. This capstone project aimed to address the perceived unpreparedness among clinicians through the creation of an 8-hour interactive educational workshop. The workshop is grounded in the Model of Human Occupation and informed by the Bridging the Transition …

Adapting Publishing Principles And Best Practices For Repository-Hosted Journals: Sustainable Ideas For Enhancing Local Open Access Publishing, Andrea A. Wirth

Library Faculty Research

This poster addresses the question: How can librarians and administrators working with repository-hosted journal editors incorporate best practices into hosted journals without taking on the role of publisher and without overextending themselves?

The "Principles of Transparency and Best Practice in Scholarly Publishing" (COPE, DOAJ, OASPA, WAME, 2022) provides foundational guidance for journal publishing. The guidelines cover a robust suite of topics such as authorship, peer review, funding sources, author cost transparency, and licensing and copyright. Publishers with staff who support a suite of journals (whether 10 or 1000) may be able to evaluate and adopt such guidance relatively quickly and …
