A Single Batch Synthesis Of Pure Phase Mo2c From Ammonium Molybdate: Pathway And Properties, Melek Cumbul Altay

Turkish Journal of Chemistry

This study presents an original, effective, and environmentally friendly method for synthesizing pure molybdenum carbide (Mo2C) from ammonium molybdate tetrahydrate (AMT) without generating carbon dioxide, a greenhouse gas. The process involves the sequential transformation of AMT to Mo2C, which follows the reaction pathway of (NH4)6Mo7O24→MoO3→MoO2→Mo→Mo2C. This transformation is achieved by strategically altering the gas atmosphere, switching from Ar to H2 at 800 K and then from H2 to CH4 at 1000 K. Thermal analysis, X-ray diffraction (XRD), and scanning electron microscopy (SEM) techniques were used to characterize AMT and the products. Mass measurements were used to follow the conversion of …

Walden Dissertations and Doctoral Studies

Nurse turnover has become a critical concern in healthcare, as low retention rates lead to decreased patient care quality and increased operational costs. A critical issue for hospital stakeholders is that many nursing leaders lack strategies to improve nursing retention. Grounded in the leader-member exchange theory, the purpose of this qualitative pragmatic inquiry was to identify and explore successful leadership strategies used by nurse managers in the Pacific South region of the United States to improve nurse retention. The study included interviews with six nurse managers who successfully implemented retention strategies. Data were collected through semistructured interviews and publicly available …

The 2 Sigma Genus Concept In Mammalogy: Lessons From Lasiurus, Amy B. Baird, Janet K. Braun, Mark D. Engstrom, Burton K. Lim, Michael A. Mares, Luis A. Ruedas, John C. Patton, John W. Bickham

Biology Faculty Publications and Presentations

Species concepts are well established and apply across diverse groups of organisms; however, there is no consensus on what defines higher taxonomic groups. The genus rank is important to taxonomists because it comprises part of the scientific name of an organism. A consistent and biologically meaningful method for determining generic status is needed for taxonomic stability and utility. Lasiurine bats are a group for which there is disagreement on how many genera to recognize. Some authors argue for splitting this group into three genera based on morphology, genetic divergence, and time of divergence; others argue that a single genus should …

No Longer At War With My Words: Finding Healing Through Therapeutic Writing, Marlo Degaetano Kreitzinger

Theses and Dissertations

While living in Dallas, Texas, I had the incredible opportunity to work with women transitioning out of homelessness, addiction, prison, or other life traumas. During my four years of facilitating life skills and job readiness classes, I witnessed a desperate need for healing. Many of the women I served were stuck in the repetitive cycle of their unprocessed emotional trauma. These women were often victims of the unprecedented mental health crisis plaguing our world and had little to no access to mental health resources. My initial introduction into therapeutic writing helped me to accept my own mental health crisis and …

Predictive Study Of The Relationship Between Self-Care And Professional Quality Of Life Among Licensed Counselors Impacted By Covid-19, Maria G. Billings

Walden Dissertations and Doctoral Studies

The COVID-19 pandemic has created unprecedented challenges for mental health professionals, significantly increasing burnout and secondary traumatic stress while reducing available resources and limiting opportunities for compassion satisfaction. The purpose of this cross-sectional, quantitative survey study was to determine whether self-care engagement predicts levels of burnout, secondary traumatic stress, and compassion satisfaction among counselors. Grounded in Stamm’s theoretical framework on compassion satisfaction and compassion fatigue, the Self-Care Assessment Worksheet (SCAW) was used to measure self-care engagement, and the Professional Quality of Life Scale (ProQOL-V) was used to assess burnout, secondary traumatic stress, and compassion satisfaction. The sample included 59 licensed …

Videos As Video Game Preservation, Scott Tyler Bradshaw

Theses and Dissertations

Video games have become culturally significant in society and are deserving of being preserved. There are many ways to preserve video games such as emulation, migration, and reissue. But recordings of video games have the special designation of being able to faithfully depict a game, which is an advantage it has over other preservation methods. This paper explores the advantages and disadvantages of various preservation methods while putting recordings forward as an equal method that can assist in its own way. Furthermore the concept of documentary style videos for video games is explored with input by archivists as well as …

Bkk1/Bak7 And Tcp21 Form A Positive Feedback Loop To Facilitate Submergence Tolerance In Plants, Yiyi Guo, Yuanbin Zhang, Yuanyuan Li, Jie Liu, Yiyang Hu, Jiazhi Jiang, Qi Li, Yeke Chen, Weizhen Hu, Lixi Jiang, Ronghui Pan, Dezhi Wu, Jie Dong

Publications

Submergence poses a deleterious threat to plant development and the agricultural production of Brassica napus (B. napus), an important worldwide oil crop. However, the molecular mechanisms underlying submergence tolerance in B. napus remain elusive. Here, through a genome-wide association study, we identify a SOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASE, BKK1/BAK7, which is crucial for plant survival after submergence stress. Submergence rapidly activates the expression of BAK7 and induces the accumulation of its kinase domain in the nucleus. BAK7 interacts with and phosphorylates class I TEOSINTE BRANCHED1, CYCLOIDEA, PROLIFERATING CELL FACTOR 1 and 2 (TCP) transcription factor TCP21, thereby stabilizing it and modulating …

Who's At Home?: Individual-And Family-Level Sociodemographic Characteristics Associated With Stay-At-Home Motherhood, Deegan Minchey

Theses and Dissertations

In this study, I assess the relationship between various types of demographic variables, including individual, partner, and family-level information, and the likelihood of mothers staying at home. Using nationally representative data from the 2019,2021, and 2023 waves of the Annual Social and Economic Supplement (ASEC) to the Current Population Survey to account for differences across the COVID-19 pandemic, this analysis examines the likelihood of becoming a stay-at-home mother (SAHM) across three separate regression models. From the variables analyzed, I find that various individual, family, and partner demographic characteristics are significantly associated with the likelihood of becoming a SAHM. These results …

Tweaking Ml-Kem (Kyber) And Ml-Dsa (Dilithium), Kumar Rahul

Master’s Dissertations

Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn as the foundation for secure cryptographic systems. Attractive features of lattice cryptography include apparent resistance to quantum attacks (in contrast with most number-theoretic cryptography), high asymptotic efficiency and parallelism, security under worst-case intractability assumptions, and solutions to long-standing open problems in cryptography. This work surveys the structure, security, and optimization potential of two leading lattice-based cryptographic schemes: ML-KEM (Kyber) and ML-DSA (Dilithium). Special attention is given to their applicability in government-oriented post-quantum cryptographic systems, focusing on performance, implementation considerations, and resilience against known quantum threats. In …

Gender Differences In Regretted Consensual Sexual Experiences And Problematic Alcohol Use Among First-Year College Students, Shannon Shen, Soyoung Kwon, Sukho Lee

Journal of Social, Behavioral, and Health Sciences

Regretted sexual behaviors and alcohol use often occur in tandem for college students; however, few studies have examined their interrelationships or the variance across gender. This study tested gender differences in how regretting a consensual sexual experience is related to college students’ alcohol use. One hundred and forty first-year students (63% women, 69% Hispanic) surveyed in 2018 and 2019 reported their sexual behavior and alcohol use (following the Rutgers Alcohol Problem Index [RAPI]). Twenty-one percent of men and 16% of women reported a regretted sexual encounter. Interaction effects from regression models revealed that men with sexual regret had a significantly …

Walden Dissertations and Doctoral Studies

The project was an educational DNP project that aimed to improve staff knowledge on genetic testing. The practice focused question was “Will an education module on best practices for genetic testing increase self-reported knowledge among health care professionals in a mental health clinic?” The purposes of genetic testing in psychiatry are to improve pharmacological therapy through better prescription of the right medications (Pinzón-Espinosa et al., 2022). The implementation of genetic testing at the project site is limited due to gaps in knowledge and attitudes as well as efficacy of this intervention. The leaders at the practicum site supported the potential …

Changes In Rfi Values Of Omomyid Mandibular Molars In Response To Climatic Shifts, Hannah Vanooteghem

Masters Theses

Molar anatomy reflects the functional demands of food mastication, and dental topography provides a quantitative method for evaluating how molar structure relates to dietary niche. Relief index (RFI), a dental topographic measure, has been successfully used to infer diet in extant and fossil mammals. This study tests two hypotheses regarding mandibular molars of early Eocene omomyids: (1) There is an association between changes in omomyid RFI values of first and second mandibular molars and changes in climatic variables (temperature and precipitation) from Wa0 to Wa5, and (2) The first and second mandibular molar RFI values of omomyid species are significantly …

Inverse Problem Of Class Of Delay Differential Equations And Fast Estimation Of Parameters, Ibrahim Makki Khalil, Jehan Mohammed Khudhir

Baghdad Science Journal

This article introduces an integral representation formula to solve delay nonlinear ordinary differential equations (DDEs) as an improvment to the method proposed by Tyukin I, et al. of solving a class of ordinary differential equations. The integral formula depends on the parameters of the systems explicitly as nonlinear parameterized computable functions. It features both linear and nonlinear equations and show an effective form for estimating unknown parameters. Solutions of DDEs are represented as sums of computable integrals which are implicitly dependent on the initial condition and the unknown parameters. This allows invoking parallel computational streams using Matlab tools of sums …

Numerical Solution Of Distributed Order Fractional Differential Equations Using Spectral Mittag-Leffler Weight Function Based On Chelyshkov Polynomials, Abdulrazzaq T. Abed, Ekhlass S. Al-Rawi

Baghdad Science Journal

In many studies, spectral methods based on one of the orthogonal polynomials and weighted residual methods (WRMs) have been used to convert the distributed-order fractional differential equation (DOFDEs) into a system of linear or nonlinear algebraic equations, and then solve this system to obtain the approximate solution. In this paper, a numerical method is presented for solving DOFDEs. The approximate solution is imposed as an orthogonal Chelyshkov polynomial with unknown coefficients. The required coefficients are obtained using WRMs, which transform the DOFDEs into a system of algebraic coefficients. The Mittag-Leffler function is proposed as a suitable weight function. The method …

Baghdad Science Journal

This paper analyzes the M/G (P1, P2)/1 queue using a single server that provides essential services in both the first phase (FPS) and the second phase (SPS). It was assumed that the server undertakes unreliability due to starting failure (SF) during the beginning of the first phase with probability (α) or service begins by the idle server successfully with probability (1-α) for the arriving or retrial customer. Then immediately took the failed server for repair and launched the customer into orbit. Also, the server operates at varying rates instead of fully ceasing service during its vacation. …

Common Fixed Points Results For Three Mappings Under Generalized Contraction Of Suzuki-Type In Ƀ-Metric Spaces With Application, Surjeet Singh Chauhan Gonder, Manju Devi, Manish Jain, Mohammad Sajid

Baghdad Science Journal

Suzuki used a brilliant strategy in his seminal publications to expand the Banach contraction theorem (BCT). This has undergone numerous intriguing generalizations and extensions during the past few decades and led to a new trend of coincidence and fixed points for countless Suzuki-type contractive and non-expansive maps in the various spaces. In this article, in the setup of ƀ-metric spaces, the aim is to produce a common fixed point of three mappings subjected to a generalized contraction of the Suzuki type. The present work generalizes well- known results of Suzuki, Chandra et al., Roshan et al. and several other results …

Improving Golden Eagle Optimization Algorithm Through Using Wavelet Mutation, Ebtehal Talib, Abeer Salim Jamil, Nidaa Flaih Hassan

Baghdad Science Journal

The Golden Eagle Optimization (GEO) algorithm is another amazing nature inspired optimization algorithm based on the foraging behavior of the Golden Eagles. GEO is an excellent behavioral model of how Golden Eagles interact with one another while searching for prey, consisting of a population of virtual “eagles” that together represent potential solutions to the optimization problem. The “eagles” interact with one another and together communicate and move as a single unit towards something, in this case the optimal solution. In this paper, we expand upon this idea with a new version of the GEO algorithm, called Wavelet Mutation Golden Eagle …
