Authors: Чернышов Данил Алексеевич , Ковалев Алексей Викторович 
Published: October 2022

В работе в аналитическом виде определяется напряженно-деформированное состояние сплошного шара, подвергнутого равномерному тепловому воздействию, и вводятся предположения о характере влияния на него зависимости предела текучести от температурного поля. В качестве материала шара рассматривается модель сплошной среды, предложенная А. Н. Спорыхиным (модель упрочняющегося упруговязкопластического материала). Решение задачи представляет собой обобщение уже известного подхода на случай полиномиальной зависимости предела текучести от температуры. В результате расчетов получены численные значения основных величин, и проведено сравнение материалов, предел текучести которых определяется постоянной, линейной и квадратичной функциями.
In this work, the stress-strain state of solid ball subjected to uniform thermal action is determined in an analytical form and assumptions about of the influence of the dependence of the yield strength on the temperature field on it are introduced. The continuous medium model proposed by A. N. Sporykhin (a model of a hardening elastoviscoplastic material) is considered as the ball material. The solution of the problem is a generalization of the already known approach to the case of a polynomial dependence of the yield strength on temperature. As a result of computation, numerical values of the basic quantities were obtained, and a comparison was made of materials whose yield strength is determined by constant, linear and quadratic functions.
Stellar Energetic Particle Transport in the Turbulent and CME-disrupted Stellar Wind of AU Microscopii

Published: October 2022

Abstract
Energetic particles emitted by active stars are likely to propagate in astrospheric magnetized plasma and disrupted by the prior passage of energetic coronal mass ejections (CMEs). We carried out test-particle simulations of ∼GeV protons produced at a variety of distances from the M1Ve star AU Microscopii by coronal flares or traveling shocks. Particles are propagated within a large-scale quiescent three-dimensional magnetic field and stellar wind reconstructed from measured magnetograms, and within the same stellar environment following the passage of a 1036 erg kinetic energy CME. In both cases, magnetic fluctuations with an isotropic power spectrum are overlayed onto the large-scale stellar magnetic field and particle propagation out to the two innnermost confirmed planets is examined. In the quiescent case, the magnetic field concentrates the particles into two regions near the ecliptic plane. After the passage of the CME, the closed field lines remain inflated and the reshuffled magnetic field remains highly compressed, shrinking the scattering mean free path of the particles. In the direction of propagation of the CME lobes the subsequent energetic particle (EP) flux is suppressed. Even for a CME front propagating out of the ecliptic plane, the EP flux along the planetary orbits highly fluctuates and peaks at ∼2–3 orders of magnitude higher than the average solar value at Earth, both in the quiescent and the post-CME cases.

Abstract
M82 X-2 is the first pulsating ultraluminous X-ray source discovered. The luminosity of these extreme pulsars, if isotropic, implies an extreme mass transfer rate. An alternative is to assume a much lower mass transfer rate, but with an apparent luminosity boosted by geometrical beaming. Only an independent measurement of the mass transfer rate can help discriminate between these two scenarios. In this paper, we follow the orbit of the neutron star for 7 yr, measure the decay of the orbit (

), and argue that this orbital decay is driven by extreme mass transfer of more than 150 times the mass transfer limit set by the Eddington luminosity. If this is true, the mass available to the accretor is more than enough to justify its luminosity, with no need for beaming. This also strongly favors models where the accretor is a highly magnetized neutron star.
The Behavior of HgMn Stars in the Far-UV—Paper 15: HD 216494
Authors: Monier Richard 
Published: October 2022

Abstract
The analysis of high resolution spectra of the HgMn star HD 216494 recorded by the SWP camera on board the International Ultraviolet Explorer reveals no variations of the far-ultraviolet flux of this star over 2 days in 1995 July. The far-ultraviolet resonance lines of Si ii are strong absorbers in the spectrum of HD 216494. The resonance lines of Ga ii, Ga iii and Hg ii, characteristic of classical HgMn stars, are also present in the mean SWP spectrum of HD 216494. The currently available TESS lightcurves of HD 216494 has a double wave structure with a period between two successive deep minima equal to 3.486 ± 0.054 days which could be the rotation period.
Combat à poings nus, réussite incertaine : pourquoi les jeunes s’engagent-ils dans la lutte sénégalaise avec frappe ?
Authors: Tidiane Wane Cheikh , Chevé Dominique 
Published: October 2022

Au Sénégal, le football représentait, au début des années 1970-1990, le sport le plus populaire et incarnait le rêve de réussite pour beaucoup de jeunes. Force est de constater que la lutte avec frappe apparaît aujourd’hui, et depuis une vingtaine d’années, dans l’univers du Sénégal, comme le sport roi par excellence offrant des espoirs d’ascension sociale. Alors, pourquoi les jeunes Sénégalais prennent-ils le risque de s’engager dans un sport de combat dont l’issue est très aléatoire et incertaine ? L’objectif de ce travail est d’étudier l’engagement de ces lutteurs. L’étude s’inscrit dans sur une approche socio-anthropologique mobilisant deux outils méthodologiques : l’observation participante et des entretiens semi-dirigés, pour accéder au sens et aux motifs à l’origine de la prise de risque dans l’engagement des lutteurs. Les résultats montrent que la construction sociale des parcours de ces sportifs est le fruit d’un processus complexe et multidimensionnel, qui interdit toute vision essentialiste du « talent » sportif comme toute réduction à une « fabrique de champions ». Les lutteurs, confrontés à une grande précarité et souvent à une extrême pauvreté, investissent la lutte sénégalaise avec frappe dans l’espoir d’un lendemain meilleur et développent des stratégies pour donner du sens à leur engagement.
Arts martiaux traditionnels et énergie : (ré)interprétations contemporaines
Authors: Legendre Alexandre , Okui Haruka , Obœuf Alexandre , Ferrer Marie-Hélène 
Published: October 2022

Le présent article porte sur les réinterprétations contemporaines du concept d’énergie associé aux pratiques martiales traditionnelles et cherche à en expliciter les mécanismes afin d’éclairer certains usages et attentes manifestés à l’endroit du corps par les sociétés modernes. Après avoir clarifié le cadre culturel et sémantique complexe dans lequel l’idée d’énergie a évolué en Occident comme en Orient, il montre combien les concepts vernaculaires de jing et energy , qui caractérisent les arts martiaux en tant que pédagogies corporelles, ainsi qu’une quadruple enquête ethnographique l’aura révélé, s’avèrent irréductibles au concept de qi / ki autour duquel s’articule le discours contemporain. Cette dernière assimilation conceptuelle aussi problématique sur le plan théorique que pratique sera finalement imputée à la tendance à la spiritualisation qu’accusent les arts martiaux traditionnels à la faveur, 1) de leur transculturation, en l’espèce, du remodelage du concept d’énergie sur le cadre dualiste de la pensée occidentale ; 2) de l’inversion de leurs moyens et fins à la suite du déclin de leur utilité initiale, et leur instrumentalisation incidente au service de la culture de soi ; 3) du phénomène de dématérialisation des corps, qui conduit à s’attacher aux manifestations les plus subtiles de l’énergie.

Educação em Direitos Humanos no currículo: ensinando e aprendendo por meio de portfólios
Authors: Klein Ana Maria , Oliveira Flaviana de Freitas , Costa Juliana dos Santos , Santos Paula Toledo Lara dos 
Published: October 2022

O artigo apresenta a análise documental de um corpus constituído por 95 portfólios elaborados em uma disciplina de Educação em Direitos Humanos (EDH) ofertada em um programa de pós-graduação stricto sensu. Portfólios foram utilizados como estratégia metodológica para abordar conteúdos relacionados aos Direitos Humanos (DH), numa perspectiva interdisciplinar e transversal, priorizando a percepção destes direitos a partir da realidade. No início da disciplina, durante 5 semanas consecutivas, os estudantes elaboraram portfólios atendendo à proposta de trazerem algum Direito Humano com o qual se depararam por meio do veículo por eles escolhido, por exemplo: notícias, músicas, filmes, imagens, dentre outros. Trata-se de uma pesquisa aplicada com abordagem qualitativa, desenvolvida por meio de análise documental, cujos objetivos foram: analisar os DH presentes nos portfólios; levantar os veículos utilizados para identificar os DH. A análise do material foi realizada por meio da categorização dos Direitos Humanos e dos veículos. Os resultados demonstram que a maior parte dos portfólios analisados, 65%, referem-se aos direitos civis e políticos. Em 24% dos portfólios estão os direitos econômicos, sociais e culturais (DESC). O terceiro grupo, com 11% de portfólios, destaca direitos difusos e coletivos, que se caracterizam por se destinarem a um grupo, categoria ou conjunto específico de pessoas que tem algum tipo de vínculo, algo em comum. O veículo mais presente dentre os trabalhos analisados foram os que divulgam notícias, com 44% de portfólios; em seguida, os veículos relacionados à arte como imagens, músicas, quadrinhos e poemas com 41% dos portfólios. O uso de portfólios favoreceu a percepção e a discussão dos Direitos Humanos de maneira contextualizada, indicando também os diferentes veículos que podem contribuir para a abordagem destes conteúdos em sala de aula.
Meaning Making Among Professional Master's Athletic Training Students
Authors: Myers Sarah Lynn , Taylor Kari B. , Singe Stephanie Mazerolle , Barrett Jessica L. 
Published: October 2022

Context
New approaches to education and pedagogy are needed in athletic training education to better support developmental benchmarks that cultivate skills for lifelong learning.

Objective
Explore and understand students' perceptions of their education and how those perceptions support their development toward self-authorship through the complexity of their meaning making.

Design
Qualitative, grounded theory.

Setting
Division I Commission on Accreditation of Athletic Training Education athletic training programs.

Patients or Other Participants
Twelve participants (9 female, 3 male; age = 24 ± 2 years) in their second year of athletic training education were recruited for the study. Of the 12 participants, 11 were engaged in an immersive clinical experience.

Data Collection and Analysis
Participants engaged in a semistructured video conference interview. Data were analyzed using grounded theory approach to understand the complexity of students' ways of making meaning cognitively, intrapersonally, and interpersonally. Data saturation, peer review, member checks, and theoretical triangulation were used to establish credibility.

Results
Participants exhibited meaning making in 2 distinct ways: (1) external guidance and (2) movement toward internal guidance. The categories were further broken down by theme. Placing responsibility for knowledge on authorities, need for step-by-step guidance, and seeking approval marked the themes of external guidance. Building confidence and role identity development marked themes of movement toward internal guidance.

Conclusions
Participants who were reliant on external guidance required external authorities for knowledge acquisition and learning. Some participants demonstrated deeper meaning making when discussing their experiences with clinical education.
Addressing the Habitual Practice Issue: The Role of Unlearning in Promoting Evidence-Based Practice and Lifelong Learning
Authors: Pike Lacy Alicia M. , Lam Kenneth C. , Welch Bacon Cailee E. 
Published: October 2022

Context
Habits play a large role in health care professionals' behaviors. Although habitual practice patterns limit cognitive overload, routinized approaches can compromise the provision of quality and contemporary patient care. To address the issue of habit, unlearning has been suggested across health care fields but remains a relatively new concept in athletic training.

Objectives
This commentary aims to (1) describe the concept of unlearning, including barriers to and facilitators of this process, (2) discuss the steps in the unlearning process via a published unlearning framework, (3) highlight the role of unlearning on improving evidence-based practice and lifelong learning among clinicians, and (4) apply a context-specific example to the unlearning framework to highlight the role of unlearning on improving patient care.

Background
Although evidence-based practice can result in improved quality of care, literature suggests that routine uptake and incorporation of evidence into patient care is limited. The reason for this gap is likely multifactorial, but may, in part, be related to the need for unlearning.

Synthesis
Rapid changes in health care delivery require medical professionals to adapt their practice behaviors to maintain competence over time. Unlearning facilitates behavior change because it involves an intentional act of moving away from knowledge and skills that are no longer effective. As such, unlearning may also improve evidence-based practice efforts.

Recommendation(s)
To abide by changing recommendations, clinicians must unlearn outdated behaviors first before replacing them with evidence-based techniques. As new knowledge is acquired, it is important to reflect on its applicability to one's practice setting and identify what, if any, outdated practices the new knowledge could replace.

Conclusion(s)
Self-reflection is essential for successful unlearning to occur. Identifying the overall effectiveness of various practice behaviors and acting on areas of improvement can help ensure the care provided to patients is evidence-based while simultaneously optimizing patient outcomes.
Integration and Outcomes of a Hybrid Simulation for Simple Laceration Suturing
Authors: Winkelmann Zachary K. , Neil Elizabeth R. , Eberman Lindsey E. 
Published: October 2022

Context
Emergency and immediate care skills are often difficult to practice in real time during clinical education. One immediate care skill requiring advanced training that may not be implemented during clinical education is wound closure via suturing. Simple laceration management with sutures can be advantageous skill for athletic training students to learn and practice; however, deliberate practice with feedback in a realistic manner is necessitated.

Objective
To describe the use of hybrid simulation to practice suturing in professional and postprofessional athletic training programs.

Background
The practice of immediate and emergency skills is predominately classroom based and removes the patient experience. Simulation-based learning has provided athletic training educators an opportunity for skill practice with patient simulators and standardized patients to fill the gap.

Description
The hybrid simulation incorporates the use of a standardized live patient actor with an attached part-task–training simulated arm for suturing in a safe and realistic manner.

Clinical Advantage(s)
Incorporating a hybrid simulation encounter for practice of suturing skills requires multitasking and delivery of patient-centered care and promotes proper skill execution while receiving questions and direct feedback from the standardized patient.

Conclusion(s)
Suturing should be taught and assessed in a tiered format using part-task trainers such as pig skin and artificial skin pads. After skill development, a hybrid simulation as a summative assessment allows for the educator to evaluate the learners' interpersonal communication and technical skills in a safe manner.
Evaluation of Fungal Elements in Dystrophic Nails Using Chicago Sky Blue Stain
Authors: Revathi T. N. , Aithal Sowmya S. 
Published: October 2022

Background:
Dystrophic nails represent an alteration in nail morphology that can occur due to various disorders. Although KOH is used commonly in the diagnosis, the sensitivity and specificity of KOH are less. Chicago sky blue (CSB) stain when used with KOH provides color contrast, to aid the detection of fungal elements, and is a simple and inexpensive method.

Materials and Methods:
Nail scrapings from the surface and subungual areas and nail clippings were examined with 40% KOH, CSB stain, and also subjected to fungal culture.

Results:
The detection rate of fungal elements in dystrophic nails in our hospital-based study was 46.5%. The sensitivity of KOH was 36.36% and CSB staining was 66.6% using fungal culture as a gold standard.

Conclusion:
CSB stain serves as a useful, simple, and rapid method for detecting the presence of fungal elements.
Macronutrient cycling in hydroponic lettuce cultivation
Authors: Macedo Priscila Helena da Silva , Lopes Emily Mariano da Cruz , Lopes Mariano  Vieira dos Santos de Souza , Sala Fernando César , Souza Claudinei Fonseca 
Published: October 2022

In order to address issues of limited resources and contamination by fertilizers, nutrient solutions may be reused in hydroponics as an alternative to their disposal in the environment. This work evaluated the feasibility of nutrient replacement for the nutrient solutions reused during lettuce hydroponic cultivation. The experiment was carried out in an agricultural greenhouse in an NFT hydroponic system using the “Milena” lettuce cultivar. The experiment was divided into two stages: 1) monitoring and data collection and proposition of nutrient replacement management; and 2) validation of the proposed replacement management. Monitoring the consumption of the crop's nutritional solution in the first stage served as the basis for the proposed nutritional replacement management. Management was validated in the second stage through the evaluation of fresh and dry mass, crop nutritional status, and the amount of the fertilizer applied in the treatments: T1 - nutrient replacement with nutrient solution reuse; and T2 - nutrient replacement without nutrient solution reuse. The fresh and dry mass data and the amount of nutrients absorbed by the plants were submitted to the t-test at 5% probability, showing no significant difference between the treatments, making it possible to conclude that the nutrient solution reuse provided nutrient replacement during the lettuce crop cultivation.
Keywords: hydroponic system, Lactuca sativa L., macronutrient rational use.

Saccharomyces cerevisiae biomass was activated chemically, and its ibuprofen (IBP) biosorption capabilities were assessed regarding IBP removal from an aqueous solution. The effects of pH (2-10), contact time (0-90 min), IBP concentration (5-35 mg L-1), and temperature (20, 30, 40°C) were evaluated in batch studies. Higher removal rates of IBP were found at pH 2.0. The pseudo-second-order kinetic model best described the experimental data. Both the Langmuir and Freundlich isotherm models described the equilibrium data satisfactorily. The maximum biosorption capacity for IBP onto chemically activated Saccharomyces cerevisiae biomass (CA-YB) was estimated at 13.39 mg g-1 at 40°C. The activation energy calculated by the Dubinin-Radushkevich isotherm model was 9.129 kJ mol-1, indicating that a chemical process mediated the biosorption of IBP onto CA-YB. According to thermodynamic studies, IBP biosorption is spontaneous and endothermic. FTIR analysis revealed that the carboxyl, hydroxyl, phosphoryl, and amino groups were involved in the biosorption process of IBP. These findings indicated that CA-YB could be an alternative biosorbent for IBP removal from aqueous media.
Keywords: isotherms, kinetic, microbial biomass, pharmaceutical drugs, thermodynamic study.
Aspects of a unique natural limnological phenomenon in the Brazilian Pantanal
Authors: Andrade Maria Helena da Silva , Brandimarte Ana Lúcia , Calheiros Débora Fernandes , Súarez Yzel Rondon 
Published: October 2022

This study compares physical and chemical parameters of water samples collected in a marginal lake (Castelo Bay) in the Paraguay River Basin in southern Pantanal during a significant natural phenomenon of hypoxia, locally called decoada, and shortly after it. Limnological parameters were analyzed from four sampling sites along the bay. Comparisons of the physical and chemical parameters between decoada and post-decoada periods were performed by Student’s t-test, principal component analysis and multivariate permutational analysis of variance (permanova). During the period of the decoada, there was a significant reduction in mean values of water transparency and concentrations of dissolved oxygen, sodium and nitrite compared to the post-decoada period. On the other hand, water temperature and conductivity, and concentrations of orthophosphate, total nitrogen and total iron have all had higher values during the decoada period. An effect of connectivity between lake and river was found to generate a gradient of water characteristics at Castelo Bay. The limnological characteristics that differed the most between decoada and post-decoada periods are those associated with the reduction of dissolved oxygen that could cause natural death of fish and the increase in nutrients during the decoada, yet they vary on temporal and spatial scales.
Keywords: anoxia, dissolved oxygen, floodplain lakes.
