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 …

Autistic Traits In Fibromyalgia Are Associated With Hypersensitivity And Central Sensitisation, Helen Johnston, Alison Bacon

School of Psychology

Fibromyalgia presents with symptoms of central sensitisation (CS). Allodynia is the defining symptom, with evidence for general hypersensitisation extending beyond the pain symptoms that characterise fibromyalgia, to sensory and psychological domains. Generalised sensory processing sensitivity (SPS) may increase vulnerability to hypersensitisation; while a direct association exists between sensory sensitivity and autistic traits in autistic people, CS symptoms are also associated with autistic traits in a broader participant sample. This study complements previous lines of enquiry by examining the relationship between SPS, CS symptoms and autistic traits in samples with and without fibromyalgia. It proposes that SPS is indirectly associated with …

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 …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Roadside exclusionary fencing is commonly used on highways to prevent wildlife-vehicle collisions. Although it can mitigate wildlife road mortality by limiting their access to the road, it can also create a barrier for wildlife stranded within the right-of-way. On State Highway 100 in Texas, the Texas Department of Transportation installed 10 wildlife exits (WEs) to allow endangered ocelots and other wildlife to escape the fenced roadway and minimize wildlife-vehicle collisions. Our study compared three types of WE designs within the same area from 2019 to 2024 to assess their effectiveness. The first design (Design A) was without a door and …

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 …

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 …

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 …

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 …
