Abstract Isla Arena is located in the coordinate 20° 70´ N - 90° 45´ W, from Campeche, Mexico. In these estuaries, the ocean mixes with fresh water, and ecosystems are concentrated where petenes and pink flamingos proliferate. Crustaceans and mollusks abound in the sea. Despite its enormous marine wealth, there are no studies carried out on which halophilic microorganisms are present in these waters. In this work, the diversity and structure of the microbial community was investigated through a metagenomics approach and corroborated for sequencing of 16S rRNA genes. It was found that the phylum Fimicutes predominates with more than 50%, in almost the same proportion of the class Bacilli and with almost 41% of relative abundance of the order Bacillales. The sequencing results showed that one of the samples presented a high percentage of similarity (99.75%) using the Nucleotide BLAST program with a peculiar microorganism: Bacillus subtilis. This microorganism is one of the best characterized bacteria among the gram-positive ones. Our results demonstrate that B. subtilis can be an efficient source of proteases, lipases and cellulases, from halophilic microbial communities located in poorly explored areas.

Abstract The ductus arteriosus is a fetal structure that spontaneously closes in 90% of newborns. Patency 3 months after birth is considered a congenital heart disease that, if untreated, can progress to serious cardiovascular complications. This report aims to review an alternative treatment with an aortic endoprosthesis in a 49-year-old man who presented with dyspnea on moderate exertion associated with a heart murmur. He was diagnosed with persistent ductus arteriosus (PDA) with cardiac complications. Clinical management was unsuccessful and surgical treatment was indicated. Endovascular treatment with a thoracic endoprosthesis was indicated and performed successfully. Percutaneous closure is the preferred method in adult patients. Endovascular intervention using an endoprosthesis is a safe and effective option, in addition to being applicable regardless of the anatomy of the PDA. This case demonstrates the natural history of the pathology and presents a safe and effective alternative for its management.

ABSTRACT: Objective was to evaluate the accuracy of elastography in the differentiation between normal and cataract lenses One hundred forty-five eyes of 98 dogs were divided into groups according to cataract stage. Forty-twoeyes were submitted to phacoemulsification. Biometric parameters, echogenicity and echotexture patterns of the anterior, posterior and vitreous chambers, lens and retina-choroid-sclera complexes were evaluated by ocular ultrasound in modes A and B. Deformability, and color (blue color = indicated less rigid structures, color red = more rigid structures) of the lenses were evaluated by the elastogram. The shear wave velocity (SWV; m/s) was calculated in three regions of the lens, both in the cortex and in the nucleus. The SWV of nucleus was statistically different between the normal lenses and with cataracts, and between the stages of cataract (P<0.001). Healthy lenses and incipient cataracts had a more rigid nucleus. Mature cataracts presented lowest nuclear rigidity (P<0.001). On cortical region the SWV was significantly higher (P<0.01) in intumescent and incipient cataracts. SWV less than 2.67m/s indicates cataract with a sensitivity of 72% and specificity of 94%. Values lower than 2.23m/s suggest mature cataract, with sensitivity of 71% and specificity of 76%. SWV greater than 2.66 m/s are associated with normal lenses or incipient cataract, presenting sensitivity of 94% and specificity of 84%. Qualitative method allowed differentiation between healthy and affected lenses and the classification of evolutionary stages. There was a correlation between the degree of stiffness of lens in cortical and nuclear regions (p=00165, r=0.37) and between the balanced saline solution quantitative and surgical time (P<0.01, r=0.73). Degree of stiffness of lens did not correlate with parameters of phacoemulsification. Elastographic proved feasible for evaluating the lens of dogs, characterizing the types of cataracts, and demonstrating increased stiffness of the diseased lenses.

ABSTRACT: Free-living wild animals can host a wide variety of endoparasites. When subjected to conditions of captivity, these animals can go through stressful situations and develop parasites. Therefore, the objective of this study was to identify parasitic infection in wild mammals, birds, and reptiles kept at the “Universidade de Caxias do Sul” Zoo, in Rio Grande do Sul state, Brazil. The population studied was based on 76 animals, divided into 50% (38/76) birds, 35.53% (27/76) mammals, and 14.47% (11/76) reptiles distributed in 33 different enclosures. Fecal samples were collected from the enclosures and analyzed in triplicate, using the centrifugal-flotation method with a zinc sulfate solution. Samples from the enclosures 31, 32, 33, (where snakes are located), and 15 (animal death), were not analyzed in triplicate, so the total number of analyses was 91 samples. The results showed that 41.76% (38/91) of the samples were positive for at least one class of endoparasites, such as Nematoda, Cestoda, or Coccidia. The positive samples showed the presence of at least one or more parasites from orders Strongylida (34.21%), Enoplida and Strongylida (23.68%), Enoplida only (23.68%), Cyclophyllidea and Oxyurida (5.26%), Ascaridida only (5.26%), Enoplida, Strongylida, and Ascaridida (5.26%), and Enoplida and Eucoccidiorida (2.63%). Considering the positive samples, 55.26% were collected from birds, 39.47% from mammals, and 5.27% from reptiles. Capillaria sp. eggs were the main structure found in birds, and eggs from the order Strongylida were the most found in samples from mammals. This study showed the order Strongylida as the most frequent parasite found in 63.16% of the total samples, established either in isolated or mixed infestations. Also, mammals and birds were those with a greater quantity of positive samples for endoparasites. Therefore, this study emphasizes the importance of carrying out research assessing the gastrointestinal parasitic fauna in wild animals, so one can determine the conditions under which these parasites become pathogenic to wild animals raised in captivity.

ABSTRACT: Salmonella is a major cause of foodborne illness worldwide, and poultry and its derived products are the most common food products associated with salmonellosis outbreaks. Some countries, including Brazil, have experienced an increased prevalence of Salmonella Heidelberg among their poultry flocks. Some isolates have also presented high resistance to antimicrobial agents and persist in the poultry farm environment. This study aimed to compare the susceptibility of S. Heidelberg strains isolated in 2006 with those isolated in 2016 against disinfectants and antimicrobial agents. The results showed that all the strains were highly susceptible to sodium hypochlorite, regardless of the conditions and year of isolation. Resistance to benzalkonium chloride varied according to the conditions applied, but not to the year of isolation. Increased antimicrobial resistance from 2006-2016 was observed only for tetracycline. The results suggest that the antimicrobial and disinfectant resistance of S. Heidelberg did not increase for ten years (2006-2016). However, further analysis should include a larger number of S. Heidelberg isolates from poultry origin and additional antimicrobial agents for more precise conclusions about the increasing in antimicrobial resistance in the last years.
Simulação interativa do interferômetro de Michelson usando o GeoGebra

Published: September 2021

Neste trabalho apresentamos uma simulação do interferômetro de Michelson que foi concebido originalmente por A. A. Michelson para determinar a velocidade da Terra em relação ao éter. A simulação foi criada utilizando o programa GeoGebra para ser utilizada como atividade remota em substituição às aulas experimentais durante o isolamento social imposto pela pandemia de Covid-19. A simulação desenvolvida permite a determinação do comprimento de onda da luz para três cores diferentes bem como a determinação dos índices de refração de quatro gases. Semelhante ao experimento real realizado com equipamentos direcionados para laboratórios de ensino de física, o interferômetro de Michelson simulado apresenta resultados com erros de medições de mesma natureza dos apresentados nas práticas presenciais feitas no laboratório. Os relatórios de práticas produzidos pelos alunos que utilizaram a simulação nos levam a acreditar que a simulação representa uma boa alternativa ao experimento real quando o mesmo não pode ser realizado.
Eficiência e sustentabilidade: uma análise econômica, social, ambiental e sustentável das usinas paulistas de cana-de-açúcar
Authors: Silva Gabriel Malta Campos Dotta e , Périco Ana Elisa
Published: September 2021

Resumo: Com a recente transformação da economia capitalista, a preocupação com as questões ambientais das atividades econômicas têm sido elemento chave na manutenção da relação competitividade-sustentabilidade. No que tange à economia brasileira, observa-se heterogeneidade nas eficiências das cadeias produtivas, devido às características legais e políticas existentes no país. O setor sucroenergético brasileiro, presente e com forte influência na economia desde períodos coloniais, além de ser pioneiro na substituição do uso de recursos fósseis por meios renováveis, constitui um campo marcado por diferenças produtivas significantes. Nesse contexto, o objetivo do artigo é analisar a eficiência das usinas de cana-de-açúcar do estado de São Paulo, no período de 2007 a 2016, sob as óticas econômica, social, ambiental e sustentável, via metodologia de Análise Envoltória de Dados (DEA), gerando modelos de eficiência robustos e completos. Foi observado que as usinas de grande porte possuem alta eficiência econômica, devido a economias de escala, além de que as usinas de porte pequeno obtiveram alto ranqueamento nas óticas social e ambiental, demonstrando que não há necessariamente viés de grandeza operacional nessas análises. Por fim, nota-se a preponderância de usinas sustentáveis benchmarks para as unidades de portes grande e pequeno, conjuntamente com o perfil etanol.
Atravessamentos metodológicos na pesquisa em Comunicação
Authors: Wottrich Laura
Published: September 2021

Resumo O texto1 assume a centralidade da metodologia para a configuração do conhecimento comunicacional, a partir das suas processualidades investigativas. Ou seja, toma a metodologia não como um a priori, mas como um processo em que o pesquisador, ao configurar uma investigação, é também configurado por ela. O enfoque é discutir os processos de aprender e ensinar metodologia na Comunicação, formado por três atravessamentos: epistemológicos, políticos e subjetivos. A exploração dessas dimensões indica que o amadurecimento metodológico do campo comunicacional passa pelo debate da dependência epistêmica, das vinculações entre teoria e metodologia e da reflexividade, além do estímulo à curiosidade epistemológica e à configuração de lugares de escuta.
Cidadania nas organizações empresariais: provocando reflexões sobre respeito à diversidade
Authors: Peruzzo Cicilia Maria Krohling
Published: September 2021

Resumo Este texto discute a discriminação social nas organizações. O objetivo é refletir sobre conceitos que embasam a compreensão da relação entre direitos humanos e de cidadania para melhor entender a questão do respeito à diversidade nas organizações como algo mais complexo do que o oportunismo para aumentar a lucratividade. Baseia-se em pesquisa bibliográfica e documental numa abordagem preliminar, portanto, sem a pretensão de esgotar a problemática. Conclui-se que a cidadania pode ser mais bem compreendida se tomada na perspectiva da dupla intersecção entre os direitos civis e os direitos cívicos. Os direitos cívicos remetem a um sentido universalizante dos direitos da pessoa, de um povo e da própria espécie humana.
Um panorama da cartografia no Brasil: uma investigação a partir das teses e dissertações da Comunicação entre 2010 e 2017

Published: September 2021

Resumo Neste artigo, buscamos esclarecer aspectos fundantes da cartografia e apresentar resultados de uma pesquisa que tem por objetivo investigar os modos de uso do método como aporte metodológico pela área da Comunicação no Brasil. Para tanto, apresentamos inicialmente um mapa desse método e examinamos o estado da arte a partir de teses e dissertações defendidas no período entre 2010 e 2017. É possível perceber, em algumas pesquisas, a adoção do termo como sinônimo de outros procedimentos metodológicos, bem como o uso superficial do arcabouço epistêmico-metodológico disponível. Foi possível identificar cinco perspectivas cartográficas que vêm ganhando destaque em função da base epistemológica empregada: a baseada em Deleuze e Guattari, a apoiada em Walter Benjamin, a Cartografia das Controvérsias (respaldada pela Teoria Ator-Rede), a apoiada nos estudos de Martín-Barbero e a cartografia poética proposta por Lucia Leão.

Resumo Neste artigo, discorremos sobre comunicação organizacional com os objetivos de evidenciar estratégias acionadas pelas organizações em perspectiva de reduzir e/ou direcionar sua (in)visibilidade nas mídias sociais e de problematizar tais práticas em perspectiva do interesse público. Para isso, acionamos dados de pesquisa realizada por Da Silva (2018), que evidencia um conjunto de sete estratégias empregadas por organizações com atuação no Brasil para gestão de sua (in)visibilidade nas mídias sociais. Complementarmente, em perspectiva do interesse público, evidenciamos que tais estratégias também são empregadas por organizações para fins que não são orientados pela ética e, mesmo, para ações ilícitas.

ABSTRACT Objective: to understand the experience of families facing cancer in palliative care of one of its members. Method: this is a qualitative research based on the theoretical-methodological framework of Grounded Theory. Six families participated, totaling 15 people. Data were collected from January to December 2019 in the homes of families in a municipality in southern Brazil, through an in-depth interview with the construction of a genogram. Analysis followed the constant comparative method steps: open, selective and theoretical coding. Results: the concepts discovering cancer; suffering with the reality imposed by the illness; preparing to face illness; deciding on treatment; facing the finitude of life, they are part of the central category “Living one day at a time”, which symbolically defines families’ experiences. The substantive theory elaborated shows that the definitions, actions and strategies adopted by families, in family dynamics and in interpersonal interactions, along a trajectory that culminates in the terminality of a relative’s life, is permeated by hope maintenance. Conclusion: throughout the illness experience, families promote changes in their daily lives and in family dynamics, undergoing adaptations and using their internal strengths in an attempt to re-establish the balance prior to the disease. Families live with uncertainty about the future, but it is the hope that drives them to live one day at a time.

Published: September 2021

Resumo O tucumã é um fruto amazônico, possui alto poder nutricional e é utilizado em diversos segmentos econômicos. Portanto, estudos para a redução de umidade devem ser realizados para o aumento do tempo de prateleira deste fruto. Este trabalho tem como objetivo realizar o estudo de secagem do epicarpo (casca), mesocarpo (polpa) e endocarpo (amêndoa) do tucumã nas temperaturas de 60 ºC, 70 ºC e 80 ºC. Foi observado que o aumento da temperatura reduziu o tempo de queda da razão de umidade do epicarpo, mesocarpo e endocarpo. Modelos matemáticos foram utilizados para estimar dados experimentais e foram calculadas propriedades termodinâmicas do processo. Baseado no maior R2 e o menor SE e DQM, o modelo Logístico apresentou melhor ajuste para cinética de secagem dentre os avaliados, estimando energia de ativação de 39,50 kJ mol-1, 46,62 kJ mol-1 e 17,76 kJ mol-1 para o epicarpo, mesocarpo e endocarpo, respectivamente. Os resultados das propriedades termodinâmicas mostraram que a entalpia (ΔH) caracteriza a secagem como um processo endotérmico. A entropia (ΔS) diminui com o aumento da temperatura. Os valores da energia de Gibbs são positivos, ou seja, o processo é não espontâneo e necessita de energia externa para difusividade da água no ar.
Complex coacervates between bovine serum albumin and anionic polysaccharides: formation and characterization
Authors: Ferreira Lorena Oliveira , Santos Monique Barreto , Garcia-Rojas Edwin Elard
Published: September 2021

Abstract The comparative study regarding complexes coacervated between Bovine Serum Albumin (BSA) and different polysaccharides, Pectin (PEC) and Gum Acacia (GA), was carried out by evaluating the influence of different ratios (protein:polysaccharide) and sodium chloride (NaCl) concentrations on turbidity and zeta potential. The BSA:PEC complexes were formed in a 10:1 ratio whereas BSA:GA at 3:1. The complexation pH showed different behavior, BSA: PEC complexes exhibited maximum turbidity in a wide pH range (4.9 to 1.5), while BSA: GA had maximum turbidity at pH 3.5. The increase in the concentration of NaCl negatively influenced the complexation. The NaCl concentration of 0.40 mol L-1 suppressed the interaction in BSA:PEC (10:1) and reduced the range formation of BSA:GA (3:1). The Fourier Transform Infrared (FTIR) demonstrated the participation not only of electrostatic interactions, but also of hydrogen bonds in the complexation. This initial study elucidated fundamental aspects about the formation of coacervate complexes between BSA:GA/PEC that assist in directing its application in food products especially, in acidic matrices (pH~4.0) as well as with low concentration of salts, in view of the effect of pH on maximum formation and sensitivity to NaCl. These complexes can be added directly to products in order to add nutritional value or even be used as a new matrix for the encapsulation of bioactive compounds.
Iron species and proteins distribution in unconventional food plants
Authors: Oliveira Aline Pereira de , Naozuka Juliana
Published: September 2021

Abstract The sustainable food valorization is capable to stimulate the local products consumption with quality and nutritional security. In this scenario, Unconventional Food Plants (UFPs) deserve attention representing an alternative for rural communities and contributing to the local and regional economy. This work aimed to add nutritional information, once it evaluates total Fe concentration, Fe-species (water soluble, acid soluble, and inorganic), proteins, and Fe- proteins distribution in beldroega (Portulaca oleracea L.), guasca (Galinsoga parviflora Cav.), ora-pro-nóbis (Pereskia aculeata Mill.), piracá (Vernonia scorpioides (Lam.) Pers.), and trapoeraba (Commelina benghalensis L.). Considering the Fe total concentration, the studied UPFs can be excellent Fe sources, when compared to foods of plant origin widely consumed and cultivated, detaching the guasca leaves (687±19 µg g-1). However, the guasca leaves showed low concentration of Fe associated to macromolecules and Fe soluble species (1.6±0.3 µg g-1). These results may justify the low bioavailability of Fe species. On the other hand, beldroega leaves presented the highest concentration of inorganic Fe (1.3±0.2 µg g-1). In the UFPs, there is high glutelins concentration when compared to the other protein groups, meaning that UFPs can be low-cost alternative to supplementing protein intake. Finally, for majority UFPs, except guasca leaves, Fe is mainly associated to albumins, being a good source of bioavailable Fe species.

Published: September 2021

RESUMO O artigo aborda os desafios da curadoria em museus universitários de história tendo como referência os debates teóricos em torno da potência documental de objetos e imagens - em contraste com sua tradicional mobilização memorial -, a ampliação do espectro de sujeitos sociais a que esses museus devem se referir e a construção de saberes e responsabilidades compartilhadas no âmbito curatorial. A renovação trazida por essas reflexões é tratada a partir dos parâmetros conceituais e da prática curatorial que animam o Museu Paulista da Universidade de São Paulo desde sua reformulação na década de 1990.

Published: September 2021

Resumo Este artigo é um recorte de um projeto maior intitulado “O empoderamento do/da adolescente para a promoção da sua saúde no contexto de uma residência multiprofissional”. Trata-se de um estudo exploratório e interpretativo de abordagem qualitativa realizado em uma escola pública estadual no contexto de uma Residência Multiprofissional em Saúde do Adolescente em um município de Minas Gerais. O objetivo foi identificar as percepções e escolhas dos(as) adolescentes em relação a sua saúde. Como técnica de coleta de dados, utilizaram-se oficinas com estudantes do Ensino Médio. Os dados foram transcritos na íntegra, submetidos à análise temática e interpretados a partir do referencial teórico da psicologia social. A análise permitiu identificar diferentes temas, organizados em três categorias: “concepções de adolescentes sobre saúde”, atreladas sobremaneira ao paradigma biomédico e à corrente moderna de promoção da saúde; “influências nas escolhas e na saúde dos(as) adolescentes”, que destacam o papel da família e das relações interpessoais; “Onde os/as adolescentes buscam saúde”, que evidencia a internet como lócus primário da busca por informações. As categorias foram discutidas em três eixos: “adolescências, saúde e seus corpos: rascunho ou potência?”, “adolescências, influências, escolhas e saúde” e “adolescências, cultura digital e saúde: articulações possíveis”. Conclui-se que, para promover saúde durante a adolescência, é preciso despir-se de concepções generalistas e dos ideais de adolescência, extrapolar os espaços tradicionais de cuidado com esse público e considerar profundamente os determinantes sociais em saúde.
Narrativas de Adoecimento de Trabalhadoras da Indústria do Vestuário em Município de Santa Catarina, Brasil

Published: September 2021

Resumo O presente estudo propôs analisar, sob a perspectiva feminista de pesquisa e da psicologia social do trabalho, os sentidos do trabalho e de gênero que emergiram das narrativas de adoecimento de trabalhadoras da indústria do vestuário de Criciúma, Santa Catarina. Trata-se de uma pesquisa do tipo empírica - com a realização de entrevistas -, de caráter exploratório e qualitativa, que parte da perspectiva do construcionismo social e da análise narrativa. Os sujeitos da pesquisa foram quatro trabalhadoras da indústria do vestuário. Evidenciou-se que o trabalho se apresenta como via de socialização e subjetivação de trabalhadoras, bem como de adoecimento, seja nos meios fabril, doméstico ou de cuidado. Com base na perspectiva de gênero, postula-se que a divisão sexual do trabalho ainda é um entrave à equidade nos contextos laborais, mediante uma atualização do caráter exploratório das atividades realizadas por mulheres, sobretudo pela invisibilidade, no âmbito reprodutivo, e pela precarização do trabalho produtivo.

Resumo O estudo das habilidades sociais contribui para a compreensão das relações interpessoais, embora ainda haja poucos estudos que relacionem esse tema a crianças com altas habilidades/superdotação (AH/SD). Portanto, os objetivos deste estudo foram: a) descrever e comparar as habilidades sociais de crianças com AH/SD sob o ponto de vista da criança e de seus respectivos pais/responsáveis e professoras; b) descrever e comparar as habilidades sociais e os problemas de comportamento de crianças com AH/SD sob o ponto de vista de seus pais/responsáveis e professoras, considerando o sexo e comparando a importância das habilidades sociais para os dois grupos; e c) descrever a competência acadêmica das crianças segundo as professoras. Participaram dez pais/responsáveis, oito professoras e dez crianças estudantes do ensino fundamental identificados com AH/SD. Os participantes responderam ao questionário Sistema de Avaliação de Habilidades Sociais (SSRS) versão para pais, professores e alunos, e ao Questionário de Respostas Socialmente Habilidosas (QRSH), versão para pais e professores. Os resultados apontaram que as crianças apresentaram habilidades sociais acima da média para seus pais e professores, e abaixo da média no autorrelato das crianças. Entretanto, há indicativos de necessidade de atenção preventiva e de intervenção nos fatores que apresentaram déficits sociais de acordo com o relato dos três grupos de participantes em: autocontrole/civilidade; cooperação/empatia; assertividade/desenvoltura social; problemas de comportamento externalizantes e internalizantes; e hiperatividade. Tais dados possibilitam que sejam programadas intervenções preventivas, conforme indicação dos pais/responsáveis e professoras, condizentes com a necessidade apontada pelas próprias crianças para a promoção de habilidades sociais.

Published: September 2021

Resumo A docência figura na lista das profissões mais acometidas pela síndrome de burnout (SB) devido à presença de uma multiplicidade de fatores. O objetivo desta pesquisa foi avaliar a frequência da síndrome em professores moçambicanos do ensino fundamental, verificando as possíveis associações com as variáveis sociodemográficas e laborais. A pesquisa de natureza quantitativa possui um delineamento observacional, analítico, transversal e envolveu 263 professores, sendo 56,3% do sexo feminino, com idades variadas entre 18 e 58 anos. A coleta de dados foi feita por meio de questionário de dados sociodemográficos e laborais do “Cuestionario para la evaluación del síndrome de quemarse por el trabajo”, versão em português para profissionais de educação (CESQT-PE). Os dados foram analisados no software SPSS (Statistical Package for Social Sciences). Os resultados indicam que 13,3% dos participantes apresentaram baixos níveis em ilusão pelo trabalho, 16,3% altos níveis em desgaste psíquico, 13,3% em indolência e 25,9% altos níveis de culpa. Na análise de perfis, 24,0% enquadram-se no perfil 1 (altos níveis da SB) e 11,0% no perfil 2 (níveis severos da SB). Verificou-se que houve associação estatisticamente significativa apenas entre a variável “idade” com a dimensão de desgaste psíquico e da variável “sexo” com a dimensão de culpa. Conclui-se que alguns professores estão em fase de desenvolvimento da síndrome, necessitando de intervenções para reverter o cenário. Esses resultados chamam a atenção dos gestores e da comunidade escolar para a necessidade de melhorar os fatores geradores de estresse ocupacional, de modo a transformar o trabalho docente em saudável e prazeroso.

Published: September 2021

Abstract Introduction: There are no studies that investigate whether different workout endings of the Pilates method (PM), either prioritizing the activation of powerhouse muscles or the relaxation of muscles trained during the session, affects spinal curvature. Objective: Identify the immediate effect of a PM session that ends with soft tissue mobilization or wall exercises on the kyphotic and lumbar lordotic angles. Methods: A crossover clinical trial with 19 female Pilates practitioners that used a Flexicurve ruler to evaluate thoracic and lumbar spine curvature before and after a PM exercise protocol, and after endings that involved soft tissue mobilization using massage balls or wall exercises. The order of the different endings was chosen by random draw and the study volunteers participated in two interventions, with intervals of seven to ten days between them. Two two-way ANOVAs were performed (one for each postural variable), using the factors “assessment time” (pre-session; post-PE; post-ending) and “type of ending” (soft tissue or wall exercises). Results: There was no significant difference between the assessment times or endings for the kyphotic (p = 0.972; p = 0.747) and lumbar lordotic angles (p = 0.574; p = 0.627), respectively. Conclusion: Pilates instructors can opt for more relaxing or more active endings without affecting the kyphotic and lumbar lordotic angles.

Published: September 2021

For high­quality steel smelting, stage­by­stage production is required, which has a complex of metallurgical units capable for producing products with high performance properties and low content of harmful impurities. One of the harmful impurities is hydrogen, so it is important to limit its content in the metal. To ensure the specifed hydrogen content, the metal in the steel out­of­furnace treatment at Converter Shop No. 2 (CS­2) of PJSC “Novolipetsk Metallurgical Plant” (“NLMK”) is subjected to vacuum treatment in a circulating vacuum degasser. Despite the prevalence of circulating vacuum derassers, theoretically, mechanism of hydrogen removal in these metallurgical units has been insufciently studied. To increase efciency of hydrogen removal, theoretical calculations were performed to remove it from the metal. There are several mechanisms for hydrogen removing: direct transfer of hydrogen from metal to the surrounding space; formation of gas bubbles in metal and their direct ascent; nucleation of hydrogen bubbles at the border of refractory wall and metal; removal of hydrogen by metal blowing with neutral gas (argon). It is shown that the main ways of hydrogen removal in a circulating vacuum degasser are direct transfer of hydrogen from metal to the surrounding space and blowing of melt with transporting gas. In the CS­2 of PJSC “NLMK”, both ways are implemented at a circulating vacuum degasser. Vacuum pumps provide pressure in a vacuum chamber of less than 101.3 Pa (0.001 atm.). It promotes intensive removal of hydrogen from the metal surface. To ensure circulation of metal, transporting gas argon is supplied to the inlet pipe of the RH degasser, which also takes part in removal of dissolved gases by transferring hydrogen to neutral gas bubbles. Additionally, performed calculations have shown that the main way of degassing in conditions of CS­2 of PJSC “NLMK” is removal of hydrogen into the bubbles of carrier gas.

Based on the studies of stress­strain metal formation during railway rails rolling in roughing stands of a universal rail­and­beam mill, carried   out using the DEFORM­3D software package, the authors have determined the features of distribution of the Cockcroft­Latham criterion over the cross­section of the rolled stock of various shapes. An extremely uneven distribution of the Cockcroft­Latham criterion over the roll section has been established. According to the data obtained, values of the specifed criterion are minimal in the axial zone, and in the near­surface layers the greatest value of the Cockcroft­Latham criterion and, accordingly, the highest probability of defects formation occur near the gauge vertical axis. In gauges of complex shape (“trapezium”, “recumbent trapezium”, rail gauges), the authors have revealed the presence of local zones with maximum Cockcroft­Latham criterion, located in the places where the foot of the rail profle is formed. And rolling in gauge of the “trapezium” type is marked by the presence of such a zone in the near­surface area near the gauge vertical axis. Within the framework of determining formation regularities of the diagram of metal stress­strain state at the initial stage of rail rolling, direct relationship was established between the uneven temperature distribution over the section of rolling and the values (maximum and average over the section) of the Cockcroft­Latham criterion. At the same time, it was shown that uneven temperature distribution over the cross­section of the roll tends to decrease with an increase in the coefcients of extracts along the passes and increase in tilting frequency, regardless of the shape of the used gauges. For gauges of complex shape, in addition to the listed parameters, an increase in similarity of shape of the roll and gauge used also has a signifcant eﬀect on reducing temperature inhomogeneity. Based on the results of theoretical studies, a new mode of railway rails rolling has been developed. Its pilot testing in the conditions of a universal rail­and­beam mill of JSC “EVRAZ ZSMK” has shown a decrease in rail rejection by 0.78 % compared to the previously used rolling mode.

The adoption of the UN Sustainable Development Goals until 2030 served as an impulse for development and implementation of regulatory legal acts aimed at environmental protection in the Russian Federation, including appropriate fnancial mechanisms. The task of reducing level of air pollution is highlighted in the UN program documents as one of the priorities. The most problematic in terms of air pollution in Russia are 12 cities, seven of which have ferrous metallurgy enterprises. The problems of ecological development of large industrial centers remain (despite the implementation of the state program of the Russian Federation “Environmental Protection” since 2012, and the national project “Ecology” since 2019) introduction of a quota system for pollutant emissions substances, determination of the list of compensatory measures and creation of the federal information system for atmospheric air quality monitoring. In cities such as Krasnoyarsk and Novokuznetsk, the average actual annual concentration of some pollutants, which are highly toxic and carcinogenic substances of I and II hazard classes, exceeds the permissible maximum by 5 – 6 times. We have analyzed content of the reports of the specialized state authorities at the regional level on state and protection of environment. It is concluded that there is no unity of methodological approaches to presentation of analytical information on state and quality of atmospheric air in reports, as well as untimely publication of the reports themselves. The fact of inertia of the institutional environment was revealed in terms of including irrelevant norms in the adopted legal acts, and as a consequence – emergence of expenditure obligations of budgets, without real need for them. It was established that large enterprises of ferrous metallurgy (Chelyabinsk Metallurgical Plant PJSC (Mechel) and Krasnoyarsk Metallurgical Plant LLC), operating in cities with very high levels of air pollution, did not draw up corporate non­fnancial reporting in the GRI format.

Nowadays initial assessment of welding quality is performed by testing equipment with increased loads (high pressure) at technical devices of hazardous production facilities. Test requirements are regulated by standardized documents of the Federal Service for Environmental, Technological and Nuclear Oversight of Russia (Rostekhnadzor). Recently, along with traditional tests, a “stress test” was used – the essence of which is to load pipeline section to the yield point, followed by leak test. However, in scientifc publications there is practically no information about physical processes occurring in the base metal and in welded joints during such tests. In addition, eﬀect of preload (deformation) on the parameters of substructure and internal stresses feld in welded joints of austenitic steels and, consequently, on the further trouble­free operation of the tested equipment was not evaluated. The paper analyzes changes in structural state and values of internal stresses in the samples of austenitic steel under the action of high loads. It substantiates the use of modulated current welding with automatic control of heat input process in molten weld pool. The admissible limits values of plastic deformation are argued when testing technical devices with high pressure for this type of steel. In order to reduce the risk of damage to austenitic steels welded joints of technical devices of hazardous industrial facilities, performed by pulsed welding with small­drop transfer, and to exclude formation of microdefects in them, high pressure tests (stress test) can be performed under loads that create deformations in metal, not exceeding 5 %. For joints welded by manual arc welding, deformations should be less than 5 %. Welded joints made by pulsed welding with large­drop transfer (with and without defects) are not recommended to be tested with high pressure.
