Using Open Alcoholics Anonymous Meetings as a Teaching Strategy for Undergraduate Nursing Students

Field: Nursing (Health Sciences)

This article describes how nursing student participation in an open Alcoholics Anonymous (AA) meeting along with journaling about the students' experiences can be used as teaching strategies to enhance learning about chemical dependence and recovery. AA participation introduced students to an easily accessible community resource and allowed them the opportunity to experientially acquire an understanding of how AA's spiritual program of recovery works. Clinical conference discussions along with the self-exploration associated with journaling afforded students the opportunity to confront and process personal attitudes and unresolved issues associated with chemical dependence. Select journal entries are included in the article to illustrate student responses to the AA experience.
High average power femtosecond laser based on ytterbium-doped crystals

Field: Physics and Astronomy (Physical Sciences)

Ce travail de thèse concerne le développement de sources femtoseconde de forte puissance moyenne ou de forte énergie avec des matériaux pompés par diodes laser, dopés à l ytterbium. Plus particulièrement au cours de cette thèse deux types de matrices ont été utilisés, le CALGO (CaGdAlO4) et les fluorures, possédant le potentiel de générer des impulsions courtes (100aine de femtoseconde). Les caractéristiques spectroscopiques et thermiques du CALGO dopés à l ytterbium permettent d envisager le développement d oscillateur femtoseconde court de forte puissance moyenne. Dans ce contexte, la technologie des disques minces permet d obtenir avec d autres matrices, des résultats très intéressants. C est pourquoi durant cette thèse le choix de maitriser cette nouvelle technologie, avec l utilisation de ce cristal, a été fait. Dans ce cadre, des résultats très prometteurs ont été obtenus. L oscillateur femtoseconde Yb :CALGO de plus forte puissance moyenne a en effet été développé (28 W), pour une énergie non négligeable, supérieure au J et une durée d impulsions de 300 fs. Des améliorations sont à prévoir avec l utilisation de nouveaux cristaux plus dopés et plus fins, mais d hors et déjà les résultats obtenus sont au niveau de l état de l art des oscillateurs femtoseconde de forte puissance moyenne.Le cristal de CaF2 quant à lui, possède un grand intérêt pour le développement d amplificateurs énergétiques courts, puisqu il a la capacité de stocker beaucoup d énergie. Deux types d amplificateurs ont alors été développés, avec des objectifs bien différents. Le premier permet d obtenir un fort gain (~106), avec une énergie extraite proche du mJ (amplificateur régénératif), alors que le second a pour but d extraire le maximum d énergie (amplificateur multipassage), dans notre cas jusqu à 160 mJ, avec un gain plus faible (~10).Le potentiel de ces matériaux pour la génération d impulsions courtes et/ou de forte puissance moyenne a alors été démontré.
Kate Bush and the Moving Image

Field: Arts and Humanities (Social Sciences)

In this unique study, Stephen Glynn demonstrates that Kate Bush's work, in both sound and vision, has long been influenced and characterised by, and at times aimed at, film and television media. The volume explores in depth Bush's 'music of allusion' and analyses first the significance of film and television references throughout the lyrics and settings of her songs, beginning with her breakthrough hit 'Wuthering Heights'. It also surveys the shaping presence of film and television in the look, narrative and artistry of her music videos, including the examination of celebrated works such as 'Cloudbusting' and 'Hounds of Love'. Finally, the book assesses Bush's most intensive cinematic undertaking, her 1993 album The Red Shoes, with its evident homage to the 1948 film of Michael Powell and Emeric Pressburger, and its concurrent visual reworking as Bush's sole film venture, The Line, The Cross & The Curve. Thus, with its deployment across music, video and film, Glynn demonstrates the centrality of Kate Bush's cinephilia to her work. Accessible yet academically rigorous, Kate Bush and the Moving Image is a stand-out study of the iconic singer-songwriter's discography and cinematic ventures. It will appeal to both students and scholars of Film, Television, Media, Cultural and Popular Music Studies.
The Cerebral Circulation, Second Edition

Field: Neuroscience (Life Sciences)

Abstract This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epit...

Multifaceted Actions of Hydrogen Sulfide in the Kidney

Field: Medicine (Health Sciences)

Gasotransmitters including hydrogen sulfide affect a wide range of cell functions. Hydrogen sulfide is synthesized by a wide variety of cells constituting the nephron, the anatomical, and functional unit of the kidney. Recent studies have shown that in aging, acute kidney injury, chronic kidney disease including diabetic kidney disease, and hypertensive disorder of preeclampsia, the generation of hydrogen sulfide is reduced in the kidney. Administration of hydrogen sulfide donors ameliorates key indices of histologic and functional injury in these disorders. Investigations to date show that hydrogen sulfide interrupts a variety of injury pathways in these states including apoptosis, oxidative stress, abnormalities in gene expression, and inflammation to name a few. The precise role of hydrogen sulfide in cancers of the genitourinary tract is controversial. Further studies are needed to improve our understanding of hydrogen sulfide regulation of kidney structure and function in both physiological and pathological conditions. At the level of our current understanding of the multifaceted functions of hydrogen sulfide in the kidney, clinical translational studies seem attractive in defined pathologic states.
In vivo radioprotective effects of basic fibroblast growth factor (FGF2) in total body irradiated C3H/HeNCr mice

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Fibroblast growth factor (FGF2) was recently found to radioprotect endothelial cells. We examined its in vivo radiomodifying effects on bone marrow in total body irradiated (TBI) mice. Female C3H/HeNCr mice were given FGF2 intravenously. Total FGF2 per mouse ranged from 1 to 24 μg, delivered 24 and 4 hr before TBI or 24 and 48 hr after irradiation. Histologic examinations were performed of the marrow and other organs, and serum cytokine levels of tumor necrosis factor-α (TNF-α), interleukin-3 (IL-3), and granulocyte-macrophage colony stimulating factor (GM-CSF) were determined from FGF2- or saline-treated mice with an enzyme-linked immunosorbent assay (ELISA) technique. FGF2 given pre-TBI significantly improved the survival of lethally irradiated mice. FGF2 radioprotection was dose-dependent and was maximized at a dose of 6 μg/mouse. The radiomodification was 1.16 ± 0.04 (±1 S.D.) with an increase of LD50/30 from 771 ± 10 to 891 ± 28 cGy. Some radiomodification was even observed when FGF2 was given 24 hr after irradiation (P < 0.05). FGF2 radioprotected mice through a mechanism that improved recovery of bone marrow hematopoietic cells. The absence of abnormal IL-3, GM-CSF, or TNF-α blood levels favors a direct proliferative effect on hematopoietic tissue rather than an indirect induction of cytokines. Other possible mechanisms of FGF2 action are discussed. Radiat Oncol Invest 1996;4:9–16. © 1996 Wiley-Liss, Inc.

Generalized lesions of the mucosa and paranasal sinuses, as well as granulomatosis of visceral organs were noted.
DERIVATION OF ELECTROMAGNETIC PROPERTIES OF CHILD BIOLOGICAL TISSUES AT RADIO FREQUENCIES

Field: Medicine (Health Sciences)

The knowledge of electromagnetic properties of biological tissues is required to assess the radio frequency energy deposition in children exposed to electromagnetic flelds. The issue whether children should be considered a dosimetric sensitive group in comparison to adults, to which the conflrmation of age-dependence of human tissue electromagnetic properties potentially may contribute remains debatable at scientiflc forums. This paper derives the formula for calculation of electromagnetic properties (permittivity and conductivity) of children tissues, as a function of height, weight, and age, respectively. By using the proposed formula, we have calculated and presented electromagnetic properties of the muscle, brain (gray matter) and skin for 1-year-old to 10-year-old children for 900MHz, 1800MHz and 2.4GHz, at which frequencies most of radio frequency devices used by children operate. The trend over the age of child electromagnetic properties has been presented, and electromagnetic properties at difierent frequencies for the same child age have also been compared. For certain tissues, comparison between the children at various age and adult electromagnetic parameters has been given. A database with electromagnetic properties for children, of all ages, tissues and frequencies may be built up with the proposed approach. It will further advance research on the assessment of children exposure to electromagnetic flelds. Formula can also be used for the determination of electromagnetic parameters for children with speciflc height and weight.

Incorporating Diffusion-Weighted Magnetic Resonance Imaging into an Observation Unit Transient Ischemic Attack Pathway

Field: Medicine (Health Sciences)

Background and Purpose: National guidelines advocate for early, aggressive transient ischemic attack (TIA) evaluations and recommend diffusion-weighted magnetic resonance imaging (MRI) for brain imaging. The purpose of this study is to examine clinician compliance, the yield of MRI, and patient-centered clinical outcomes following implementation of an emergency department observation unit (EDOU) clinical pathway incorporating routine MRI into the acute evaluation of patients with TIA. Methods: This is a prospective observational study of patients with TIA admitted from the ED. Patients with low-risk TIA were transferred to an EDOU for diagnostic testing including MRI; high-risk patients were directed to hospital admission. Clinical variables, diagnostic tests, and treatment were recorded for all patients. The primary clinical outcome was the rate of stroke or recurrent TIA, determined through telephone follow-up and medical record review at 7 and 30 days. Results: A total of 116 patients with TIA were enrolled. In all, 92 (79.3%) patients were transferred to the EDOU, of whom 69 (59.5%) were discharged without hospitalization. Compliance with the EDOU pathway was 83 (91.2%) of 92. Magnetic resonance imaging demonstrated acute infarct in 16 (15.7%) of 102 patients. Stroke (n = 2) or TIA (n = 3) occurred in 5 patients with TIA (4.3%, 95% confidence interval: 1.6%-10.0%) within 30 days; no strokes occurred after discharge. Conclusions: Implementation of a TIA clinical pathway incorporating MRI effectively encouraged guideline-compliant diagnostic testing; however, patient-important outcomes appear similar to diagnostic protocols without routine MRI. Further study is needed to assess the benefits and costs associated with routinely incorporating MRI into TIA evaluation.

Embodied Researchers: Gendered Bodies, Research Activity, and Pregnancy in the Field

Field: Social Sciences (Social Sciences)

Kathleen B. Jones, in her now famous essay about women-friendly polities, explains that that citizenship must be redefined to include a body that does not “easily fit military-corporate uniforms” (1990, 794). Jones calls theorists to recognize women's “embodied lives,” and in doing so, considers how “women's bodies are problematic” and “sex/gendered identity affects … life” (786). We argue here that recognizing women's embodied lives is similarly important to a discussion of gender and fieldwork. As researchers in the field, we have been defined by our social position as women, thus putting us at distinct disadvantages and advantages (Sundberg 2003).
Research Progress of Epigenetic Modification on the Regulation of TransportersUnder Hypoxia

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract: Epigenetic modification refers to the heritable changes caused by chromosomal changes without changing the DNA sequence. Epigenetics runs through the entire growth and differentiation process of the body, which causes varied diseases. Hypoxia is a physiological astate of lowered partial oxygen partial pressure that affects cell and tissue function. Transporters are proteins that maintain a normal and stable state of cells. Transporter's expression levels when hypoxia occurs influence the absorption, distribution, metabolism, and excretion of drugs, thereby affecting the utilization and efficacy of drugs. Epigenetic modification is assumed to play an important role in the metabolism of drugs. Changes in epigenetic modification and transporter expression levels under hypoxia are explored in our work, and the effect of epigenetic modification on transporter expression and how this regulatory mechanism works and affects drugs under hypoxia are questioned. It is important for drug development, treatment of diseases and rational use of drugs.
In Vitro Stimulation of Human Peripheral Blood Lymphocytes by Soluble and Membrane Fractions of Renografin-Purified Typhus Group Rickettsiae

Field: Immunology and Microbiology (Life Sciences)

Cell-free extracts of disrupted Renografin-purified Rickettsia typhi and R. prowazekii were evaluated as antigens in lymphocyte transformation assays for cell-mediated immunity to typhus group rickettsiae in 19 individuals with and 9 without histories of exposure to these organisms. Exposure consisted of clinical disease, vaccination with epidemic typhus vaccine, or occupational exposure to these agents. Both the soluble and membrane fractions of disrupted purified rickettsiae were used, and transformation of peripheral blood lymphocytes (PBL) was determined in microcultures by incorporation of [ 3 ]thymidine. Of the antigen concentrations tested (1 to 400 μg/ml), 10μg/ml appeared to be the most satisfactory. At this concentration, PBL transformation was highly reproducible and correlated well with donor exposure and the presence of enzyme-linked immunosorbent assay anti-typhus group immunoglobulin G. At higher concentrations, PBL from both exposed and control donors often responded to a lipopolysaccharide-like component present in these preparations. Specific transformation responses to rickettsial fractions were detected in several individuals decades after infection or vaccination, indicating that both fractions contained antigens associated with persisting cell-mediated immunity in humans. Generally, stimulation indexes with the soluble fraction were slightly greater than those obtained with corresponding concentrations of the membrane preparation, and in three individuals transformation was observed only with the soluble fraction. PBL transformation to soluble fractions also appeared to have some species specificity, since PBL from individuals with documented R. typhi infections were more responsive to the homologous soluble preparation than to the soluble fraction of R. prowazekii . PBL transformation also correlated well with homologous but only poorly with heterologous enzyme-linked immunosorbent assay immunoglobulin G titers.
Power-sharing in a re-united Cyprus: Centripetal coalitions vs. proportional sequential coalitions

Field: Social Sciences (Social Sciences)

Power-sharing coalitions in severely divided places can take centripetal or consociational forms. Respectively, these aim to foster moderation by restricting coalitions to moderate parties from different ethnic communities or inclusivity by ensuring that coalitions are broadly and proportionately representative of the main political forces. This article draws on the experience of Cyprus to show the limits of negotiating centripetal coalitions even under “most likely to succeed” conditions. It investigates a major centripetalist initiative on the island between 2008 and 2010, and explains why this failed to catalyze a negotiated settlement. Likewise, the article points to the limits of classic consociational approaches in mediating power-sharing arrangements, particularly approaches that rely on corporate ethnic quotas. Contrary to conventional wisdom and much international practice, the article shows that consociational coalitions can take a liberal form that bypass such quotas. Specifically, the article presents and defends an important innovation in consociational theory and practice: the proportional sequential (PS) coalition. PS coalitions are automatically determined by election results, and allocate portfolios on a proportionate and liberal basis amongst a divided polity’s main political parties. We argue that PS coalitions can provide a broadly inclusive and negotiable settlement in the context of a re-united Cyprus as well as in other divided polities.
The Effect of Heat Aging on the Microstructure and Properties of Spray-Deposited AlZnMgCu Alloy Extruded Plates

Field: Materials Science (Physical Sciences)

The heat-aging process, a practical aging technology that not only improves the comprehensive performance of Al alloys but also reflects the requirements of short processes, has an extremely practical significance. The effects of the heating rate and termination temperature on the “heat-aging” behavior of a spray-deposited AlZnMgCu alloy hot-extruded plate were investigated using hardness, electrical conductivity, room-temperature tensile strength, exfoliation corrosion experiments, and transmission electron microscopy microstructure (TEM) observation. The results show that as the termination temperature increases, the hardness of the spray-deposited AlZnMgCu alloy first increases to a peak and then rapidly decreases, while the electrical conductivity continues to increase. The increase in the heating rate improves the peak hardness corresponding to the termination temperature. The heat treatment process of heating at a speed of 20 °C/h to 200 °C after the spray deposition has similar mechanical and corrosion resistance properties to the RRA process and can effectively reduce the heating time from 40 h to 8 h, thus establishing a heat treatment process for spray-deposited AlZnMgCu alloy extruded plate with high aging efficiency.
Research on SLAM Localization Algorithm for Orchard Dynamic Vision Based on YOLOD-SLAM2

Field: Computer Science (Physical Sciences)

With the development of agriculture, the complexity and dynamism of orchard environments pose challenges to the perception and positioning of inter row environments for agricultural machinery. The paper proposes a method for extracting navigation lines and measuring pedestrian obstacles. The improved YOLOv5 algorithm is used to detect tree trunks between left and right rows in orchards. The experimental results show that the average angle deviation of the extracted navigation lines is less than 5 degrees, verifying its accuracy. Due to the variable posture of pedestrians and ineffective camera depth, a distance measurement algorithm based on four zone depth comparison is proposed for pedestrian obstacle distance measurement. Experimental results show that within a range of 6m, the average relative error of distance measurement does not exceed 1%, and within a range of 9m, the maximum relative error is 2.03%. The average distance measurement time is 30 milliseconds, which can accurately and quickly achieve pedestrian distance measurement in orchard environments. On the publicly available TUM RGB-D dynamic dataset, YOLOD-SLAM2 significantly reduces the RMSE index of absolute trajectory error compared to ORB-SLAM2 algorithm, which is less than 0.05 m/s. In actual orchard environments, YOLOD-SLAM2 has a higher degree of agreement between the estimated trajectory and the true trajectory when the car is traveling in straight and circular directions. The RMSE index of the absolute trajectory error is less than 0.03m/s, and the average tracking time is 47ms, indicating that the YOLOD-SLAM2 algorithm proposed in this paper can meet the accuracy and real-time requirements of agricultural machinery positioning in orchard environments.
