Understanding the Relationship Between How the Availability of Vaping Devices and Student Use Are Related: A Quantitative Study
Get PDFThe number of teens in Arkansas who are vaping continues to increase despite state and national laws and regulations. The availability of vaping devices to teens continues to occur; but limited research is available that explores if the availability is accessible through peers, families, or community members, or is self-sought. It is crucial to gain a better understanding of why vaping continues to increase among high school students in Arkansas. The purpose of this study is to understand the relationship between how the availability of vaping devices and student use are related. The analysis of exposure and student use varies by demographics, personal beliefs, and access on school campus, at school activities, in the home, or through peers will also be studied. The findings will report the demographic relationships between gender, grade, race, and access groups in relation to use and exposure. The data describing how the availability of vaping devices and student use are related will provide knowledge to educators, families, and students with the potential to provide Arkansas schools with valuable information. Gaining insights into availability and the student use relationships can allow school leaders to develop vaping-related education and prevention strategies as well as develop procedures and policies to reduce use at school and school related activities

The Wick Programming Language: A Novel Programming Language with an Interpreter and IDE
No full textWick is a novel programming language created for the purpose of gaining experience in programming language and interpreter design; two subjects that have become increasingly neglected in computer science programs. Additionally, two subjects that were captivating to our team and seemed like fun subjects for a project.
Wick is presently a simple, dynamically-typed, and multi-paradigm language, supporting. First class functions (here called subroutines) are supported as well as object-oriented programming via prototypes. A manual for writing Wick programs and some additional details of the project can be found on the interpreter\u27s GitHub repository (https://github.com/Happy-Hour-Capstone-Team/wick-interpreter).
Also provided is an online IDE (currently not hosted on a server, but can be run locally) seen on our teams GitHub page (https://github.com/Happy-Hour-Capstone-Team/wick-ide).https://github.com/Happy-Hour-Capstone-Tea

Relationship between capsule production and biofilm formation by Mannheimia haemolytica, and establishment of a poly-species biofilm with other Pasteurellaceae
Get PDFMannheimia haemolytica is one of the bacterial agents responsible for bovine respiratory disease (BRD). The capability of M. haemolytica to form a biofilm may contribute to the development of chronic BRD infection by making the bacteria more resistant to host innate immunity and antibiotics. To improve therapy and prevent BRD, a greater understanding of the association between M. haemolytica surface components and biofilm formation is needed. M. haemolytica strain 619 (wild-type) made a poorly adherent, low-biomass biofilm. To examine the relationship between capsule and biofilm formation, a capsule-deficient mutant of wild-type M. haemolytica was obtained following mutagenesis with ethyl methanesulfonate to obtain mutant E09. Loss of capsular polysaccharide (CPS) in mutant E09 was supported by transmission electron microscopy and Maneval\u27s staining. Mutant E09 attached to polyvinyl chloride plates more effectively, and produced a significantly denser and more uniform biofilm than the wild-type, as determined by crystal violet staining, scanning electron microscopy, and confocal laser scanning microscopy with COMSTAT analysis. The biofilm matrix of E09 contained predominately protein and significantly more eDNA than the wild-type, but not a distinct exopolysaccharide. Furthermore, treatment with DNase I significantly reduced the biofilm content of both the wild-type and E09 mutant. DNA sequencing of E09 showed that a point mutation occurred in the capsule biosynthesis gene wecB. The complementation of wecB in trans in mutant E09 successfully restored CPS production and reduced bacterial attachment/biofilm to levels similar to that of the wild-type. Fluorescence in-situ hybridization microscopy showed that M. haemolytica formed a poly-microbial biofilm with Histophilus somni and Pasteurella multocida. Overall, CPS production by M. haemolytica was inversely correlated with biofilm formation, the integrity of which required eDNA. A poly-microbial biofilm was readily formed between M. haemolytica, H. somni, and P. multocida, suggesting a mutualistic or synergistic interaction that may benefit bacterial colonization of the bovine respiratory tract
Contribution of Hfq to gene regulation and virulence in Histophilus somni
Get PDFHistophilus somni is one of the predominant bacterial pathogens responsible for bovine respiratory and systemic diseases in cattle. Despite the identification of numerous H. somni virulence factors, little is known about the regulation of such factors. The post-transcriptional regulatory protein Hfq may play a crucial role in regulation of components that affect bacterial virulence. The contribution of Hfq to H. somni phenotype and virulence was investigated following creation of an hfq deletion mutant of H. somni strain 2336 (designated H. somni 2336Δhfq). A comparative analysis of the mutant to the wild-type strain was carried out by examining protein and carbohydrate phenotype, RNA sequence, intracellular survival in bovine monocytes, serum susceptibility, and virulence studies in mouse and calf models. H. somni 2336Δhfq exhibited a truncated lipooligosaccharide (LOS) structure, with loss of sialylation. The mutant demonstrated increased susceptibility to intracellular and serum-mediated killing compared to the wild-type strain. Transcriptomic analysis displayed significant differential expression of 832 upregulated genes and 809 downregulated genes in H. somni 2336Δhfq compared to H. somni strain 2336, including significant downregulation of lsgB and licA, which contribute to LOS oligosaccharide synthesis and sialylation. A substantial number of differentially expressed genes were associated with polysaccharide synthesis and other proteins that could influence virulence. The H. somni 2336Δhfq mutant strain was attenuated in a mouse septicemia model and somewhat attenuated in a calf intrabronchial challenge model. H. somni was recovered less frequently from nasopharyngeal swabs, endotracheal aspirates, and lung tissues of calves challenged with H. somni 2336Δhfq compared to the wild-type strain, and the percentage of abnormal lung tissue in calves challenged with H. somni 2336Δhfq was lower than in calves challenged with the wild-type strain. In conclusion, our results support that Hfq accounts for the regulation of H. somni virulence factors

María Grever: Influence Through Mexican Folk and Classical Romantic Techniques and Ideals In ‘A Una Ola.’
Get PDFIn the last 25 years, there has been a resurgence in Latin American ethnomusicology. This means that, while interest continues to grow, there are several gaps, especially when it comes to the contributions of women. Interestingly, some of these gaps surround the popular Mexican composer María Grever. This includes the lack of information on the variety of sources she gathered inspiration from for composition. Through analyzing Grever\u27s compositional style, especially in the bolero ‘A Una Ola,’or ‘To a Wave,’ I will examine the relationship that Grever employs between the classical Romantic approach and Latin American techniques, especially Mexican folk. While consulting biographical sources that include varying levels of information about her life and works, I studied several accounts examining the role of women in music in Latin America. I also researched the evolution of Latin American techniques into the 20th century and European techniques being used in Late Romantic music. I analyzed ‘A Una Ola’ and did a comparative analysis of its relationship with similar works by Grever and other composers. I will play different recordings of ‘A Una Ola,’ one of which includes myself and another Tech student performing.
María Grever defied odds through her position as a Mexican female composer in America, and was influenced by classical Romantic ideals and traditional Latin American techniques, especially folk. Her song, ‘A Una Ola,’ exemplifies how these influences took hold in her early compositions. This paper further concludes that Grever was a major influence on not only women and Latin American composers, but on bridging the gap between traditional Mexican techniques and classical Romantic techniques, as well as bridging the gap between classical and popular music in the early-mid 20th century
