Resumo Este artigo objetivou descrever a cobertura de plano de saúde no Brasil. Foram analisados dados das edições de 2013 e 2019 da Pesquisa Nacional de Saúde. A cobertura de plano de saúde médico ou odontológico foi analisada segundo características sociodemográficas, econômicas, de trabalho, situação censitária e Unidade da Federação. A cobertura de plano de saúde médico ou odontológico foi 27,9% (IC95%: 27,1-28,8) para 2013 e 28,5% (IC95%: 27,8-29,2) para 2019. Os resultados mostram que a cobertura continua concentrada nos grandes centros urbanos, nas regiões Sudeste e Sul, entre aqueles com melhor nível socioeconômico e aqueles que possuem algum vínculo de trabalho formal. Em 2019, dentre os trabalhadores formalizados, somente 30,7% relatou que o pagamento da mensalidade é feito diretamente a operadora, sendo 72,7% dentre os trabalhadores informais. Cerca de 92% dos planos de saúde médico cobrem internação e dentre as mulheres com plano de saúde, quase 20% delas não possuem cobertura para o parto. Apenas 11,7% das mulheres com idade entre 15 e 44 anos possuem cobertura para o parto através do plano de saúde. Os resultados mostram que a cobertura por plano de saúde mantém-se bastante desigual, reforçando a importância do Sistema Único de Saúde para a população brasileira.

ABSTRACT Introduction: The use of substances to enhance sports performance among professional and amateur athletes is increasing. Such substances may either be included in the group of dietary supplements or fall into pharmacological classes. Every substance used for this purpose is called an ergogenic agent. The number of ergogenic options available increases every day, favoring overuse and use without proper guidance. Among the dietary supplements, we highlight the use of creatine, a substance widespread in sports. Among the pharmacological groups, many drugs are used. Recently the use of sildenafil citrate by professional athletes from various predominantly aerobic sports modalities was reported in the media. Objective: To compare and demonstrate the responses caused by physical training associated with the use of creatine and sildenafil citrate in mice. Methods: A swim training protocol was applied and then an electrophysiograph was used in order to obtain parameters related to contraction intensity, the area under the curve and the percentage drop. Results: The responses obtained demonstrated the ergogenic action of creatine because it altered the parameters used for measurement. The use of sildenafil citrate did not yield satisfactory results to frame the drug as an ergogenic agent. Conclusion: Creatine has an ergogenic effect, reducing the percentage drop after 10 seconds, while sildenafil demonstrated no ergogenic potential and, interestingly, resulted in weaker responses when compared to the exercise groups.

ABSTRACT Introduction: It has been shown that there is a close association between sleep quality and pain. In young athletes, sleep disorders and pain have a particularly high prevalence; however, the relationship between them has not been widely studied. Objective: To study the association between sleep quality and pain in young athletes. Methods: A cross-sectional study was conducted in which 71 young amateur athletes (39 males) were included. The mean age was 16.9 ± 1.2 years, with 6.5 ± 3.2 years of sports practice and 5.2 ± 1.2 hours of training per week. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). The participants were classified according to sleep quality, as PSQI-I = without sleep disorders, PSQI-II = requiring medical assistance and PSQI-III = requiring medical assistance and treatment. Also, pain intensity was assessed on the Numerical Rating Scale, both at rest (NRSr) and during sports activity (NRSs), along with pain duration. Results: The individuals classified as PSQI-III presented higher NRSr (Mdn = 2.0; IQR = 4.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.04) and higher NRSs (Mdn = 4.0; IQR = 5.0 vs. Mdn = 0.0; IQR = 2.0; p = 0.03) than the individuals classified as PSQI-I. No differences were observed in relation to pain duration. The PSQI score was positively but weakly associated with NRSr (rs = 0.24, p=0.046) and NRSs (rs = 0.27, p = 0.03) but not with pain duration. Conclusion: Young athletes with lower levels of sleep quality show higher levels of pain at rest and during sports practice. Therefore, sleep quality and pain should be considered in the routine assessment of young athletes, by technical and health teams. Level of evidence III; type of study: Cross-sectional .

Published: June 2021

ABSTRACT Introduction: Ischemic preconditioning (IPC) has been described in the literature as a resource capable of improving physical performance. Objective: The purpose of this randomized double-blind study was to evaluate the influence of IPC on the neuromuscular performance of trained individuals. Methods: Twenty-four (24) resistance training participants (6 of them women) with a mean age of 25.8 ± 4.6 years were selected and divided into two groups: the upper limb group (ULG) composed of 12 individuals (4 women) and the lower limb group (LLG) composed of 12 individuals (2 women). The maximum repetitions test was applied in the bench press for the ULG and in the 45° leg press for the LLG, with 50% of the one-repetition maximum under control, placebo and IPC conditions, at a random interval of 72 hours between tests. The IPC was applied four hours before the tests by means of an analog sphygmomanometer cuff inflated to 220 mmHg on the arm for the ULG and on the thigh for LLG, with three cycles of five minutes each of ischemia and reperfusion, alternating between the right and left sides. For the placebo, the cuff was inflated to 40 mmHg without causing ischemia. The significance level for the Wilcoxon test was p <0.017, due to the Bonferroni correction. The effect size (ES) was also analyzed. Results: With IPC, the ULG performed 34.8 ± 4.8 repetitions, representing an improvement of 11.29% (IPC vs. control, ES = 0.68 and p = 0.002) and the LLG performed 40.5 ± 15.7 repetitions, representing an improvement of 37.47% (IPC vs. control, ES = 0.84 and p = 0.002). No significant improvements were observed for the placebo in either group. Conclusion: Our data showed that IPC positively influenced neuromuscular performance of both the upper and lower limbs.

ABSTRACT Objective: To analyze cardiac autonomic modulation response and functional capacity in physically active older women. Methods: Seventy-five older women (60-70 years) from the community were divided into the following groups: sedentary (n=19), hydro-gymnastics (n=18), pilates (n=19), and dance (n=19). Blood pressure, body composition, heart rate variability, and functional capacity were assessed for the characterization of the groups at rest and 48 hours after the last physical exercise session. Results: The sedentary group presented higher waist-to-hip ratio, diastolic blood pressure, and resting heart rate compared to the other groups (p<0.05). It was also observed that the dance group presented better functional capacity and VO2peak scores (all p<0.05). Regarding cardiac autonomic modulation, both dance and pilates groups demonstrated better RMSSD (26.71 ± 9.07 and 29.82 ± 7.16, respectively; p<0.05), LF (45.79 ± 14.81 and 45.95 ± 15.16 n.u., respectively; p<0.05), and LF/HF (0.92 ± 0.56 and 0.58 ± 0.26, respectively; p<0.05) scores. In the symbolic analysis, the dance group had a greater predominance of parasympathetic autonomic modulation than the other groups (p<0.05). Conclusion: These results conclude that physically active elderly women, practicing hydro-gymnastics, pilates or dance, presented physiological benefits, such as better functional capacity and improvements in hemodynamic variables and autonomic cardiac modulation. In addition, the group that practiced dance presented greater parasympathetic modulation, as well as greater functional capacity, when compared to the other modalities.

Published: June 2021

ABSTRACT Introduction: The assessment of body composition in female athletes of different sports is important for health monitoring. Objective: To compare body composition in university athletes of different team sports (indoor soccer, flag football and volleyball). Methods: A cross-sectional study carried out with 45 female athletes, aged 18 to 35 years (22.8 ± 3.55). The dependent variables were body fat mass (FM) and fat-free mass (FFM) measured by air displacement plethysmography. Bone mineral content, adjusted for height (BMC/height) and bone mineral density (BMD), were measured by dual energy X-ray absorptiometry. The independent variable was sport [flag football (n = 12); indoor soccer (n = 20); volleyball (n = 13)] and the covariates were age (complete years), training volume (minutes per week) and length of time playing the sport (complete years). Analysis of covariance was used. Results: Adjusting the model for covariates, volleyball athletes (19.27 kg ± 2.20) presented higher FM values compared to the flag football (16.00 kg ± 1.70) and indoor soccer players (12.20 kg ± 1.30). There was no significant difference in FFM, BMC/height and total BMD between sports, even after adjusting for covariates. Conclusion: Volleyball athletes presented higher FM compared to flag football and indoor soccer athletes. There were no differences in FFM, BMC/height and BMD among the players of the different team sports. This study can help coaches and other sports professionals to prevent injuries to athletes in sports such as higher FM (volleyball), or to prevent diseases such as menstrual irregularities, which are common in athletes who may have low levels of body fat (indoor soccer players), this being one of the risk factors for the female athlete triad (eating disorders, menstrual irregularities and low BMD).

ABSTRACT Introduction: The indiscriminate use of androgenic steroids may have deleterious effects on human tissue. Objectives: Evaluate the effects of chronic administration of the steroid nandrolone decanoate (DECA) on autonomic cardiovascular modulation, kidney morphometry and the association between these variables in Wistar rats subjected to physical training with swimming. Methods: Thirty-two male Wistar rats aged 20 weeks were distributed among four experimental groups according to the training received: sedentary control (SC), sedentary treated with DECA (SD), trained control (TC) and trained treated with DECA (TD). The hemodynamic parameters, including blood pressure and variations in systolic blood pressure (SBPV) and diastolic blood pressure (DBPV), and kidney morphometry were evaluated. The level of significance adopted was 5%. Results: The SD group had higher baseline SBP and DBP values when compared to the SC, TC and TD groups, which were similar to each other. The rats in the SD group had higher systolic blood pressure (SBPV) and diastolic blood pressure (DBPV) variation values and higher absolute and normalized values in the LF band of the DBPV when compared to the animals in the SC, TC and TD groups. The animals in the SD group had a significantly higher rate of kidney fibrosis compared to the SC, TC and TD groups. There were no significant differences between the sympathetic modulation of SBPV through the LF component and kidney fibrosis. Conclusions: Physical training with swimming was effective in preventing the increase in blood pressure levels and lowering the occurrence of kidney fibrosis in animals treated with anabolic steroids.

ABSTRACT Introduction: High-performance athletes often undergo periods of exhaustive training and insufficient recovery, which can lead to decreased performance, but it is not clear whether there are any differences between the sexes in the level of habitual physical activity, sedentary time or sleep quantity and quality in young highly trained badminton athletes. Objectives: The aim of this study was to compare the habitual physical activity (PA), sedentary time and sleep quantity and quality of highly trained young male and female badminton athletes and non-athletes. Methods: Twenty-seven young badminton athletes and twenty-one non-athletes (control group) were recruited. Sleep duration and quality (total time in bed, total sleep time, wake after sleep onset, sleep efficiency and latency), total counts, vigorous activity time and sedentary time were measured using a tri-axial accelerometer. Results: Male athletes spent less sedentary time (p=0.028), more time in vigorous activity (p=0.016) and had higher total counts (p<0.001) than the male control group. There were no significant differences in sedentary time (p=0.702) or vigorous activity time (p=0.205) between the female athletes and non-athletes, but the female athletes accumulated higher total counts than the female control group (p=0.003). There were no significant differences between the sexes or groups for time in bed, total sleep time, sleep efficiency, wake after sleep onset and latency (p> 0.05). Conclusion: Among males but not females, young highly trained badminton athletes had less sedentary time and more time in vigorous activity than the non-athletes, however, there were no significant differences between the sexes or groups in sleep quantity and quality.

Published: June 2021

Abstract Although richness and distribution of woody species in the Cerrado physiognomies have been extensively studied, the shifts of woody species from savanna physiognomies to dry forests have not yet been addressed. Here, we investigate the effect of soil physical-chemical traits on the woody species turnover between adjacent cerrado stricto sensu and dry forest physiognomies. Woody species were surveyed, and soil and topographic variables measured, in 30 10×40 m plots systematically distributed, with 15 plots in each physiognomy. We found a spatially structured distribution of woody species, and differences of soil traits between cerrado stricto sensu and dry forest areas, mainly related to the aluminum saturation, base saturation, and available phosphorus. Aluminum saturation increased toward the savanna area, while base saturation increased toward the dry forest. Most woody species predominated in one physiognomy, such as Callisthene major in the cerrado stricto sensu and Anadenanthera colubrina in the dry forest. Only 20% of the species were widely distributed across both physiognomies or, not often, restricted to the intermediary values of the soil gradient. General results indicate that contrasting soil traits between cerrado stricto sensu and dry forest produce a strongly spatially organized and sharp transition in terms of species distribution between these physiognomies.

Abstract Allium sativum L. is an herb of the Alliaceae family with a specific taste and aroma and medicinal and nutraceutical properties that are widely marketed in several countries. Brazil is one of the largest importers of garlic in the world, despite of its production is restricted and limited to internal consumption. Thus, explore the genetic diversity of commercial garlic conserved at germplasm banks is essential to generate additional genetic information about its economically important crop. A suitable tool for this purpose is the cytogenetic characterisation of these accessions. This study aimed to characterise the cytogenetic diversity among seven accessions of garlic from a Germplasm Bank in Brazil. The karyotypes were obtained by conventional staining and with chromomycin A3 (CMA) and 4,6-diamidino-2-phenylindole (DAPI) fluorochromes. All accessions analysed showed chromosome number 2n = 16, karyotype formula 6M+2SM, symmetrical karyotypes, reticulate interphase nuclei, and chromosomes with uniform chromatin condensation from prophase to metaphase. The fluorochromes staining showed differences in the amount and distribution of heterochromatin along the chromosomes and between accessions studied. Based on the distribution pattern of these small polymorphisms, it was possible to separate the seven accessions into three groups. It was also possible to differentiate some of the accessions individually. One of the results obtained showed a heteromorphic distension of the nucleolar organiser region observed on the chromosome pairs 6 or 7 with peculiar characteristics. It was suggested for example, that the heteromorphic block of heterochromatin (CMA+++/DAPI-) on chromosome 6 of the “Branco Mineiro Piauí” accession can be used as a marker to identify this genotype or may be associated with some character of economic interest.

ABSTRACT: Leptospirosis is a worldwide zoonosis caused by the bacteria Leptospira spp. that affects humans, domestic and wild animals. The present work aimed to conduct a cross-sectional survey for leptospirosis in the canine population of the Brejo Paraibano microregion, semiarid of Northeastern Brazil. From May to October 2017, blood samples from 414 dogs were collected in the counties of Alagoa Grande (n=100), Areia (n=79), Bananeiras (n=72), Alagoa Nova (n=73), Serrraria (n=25), Pilões (n=25), Borborema (n=20) and Matinhas (n=20). The tutors of the sampled dogs answered an epidemiological questionnaire, obtaining information about the animals, owner, residence and breeding of the dogs. Subsequently, the serum samples were subjected to the microscopic agglutination test (MAT), using a collection of 23 serovar pathogenic antigens and using the 1:50 dilution as the cutoff point. Of the 414 dogs analyzed 52 were seroreactive, resulting in an apparent prevalence of 12.6% and a real prevalence of 12.2%. Seroreactive dogs were found in the eight counties. Dogs were reactive for the serogroups Icterohaemorrhagiae (76.9%), Autumnalis (13.55%), Pomona (3.8%), Grippotyphosa (3.8%) and Serjoe (1.9%) Antibody titers ranged from 50 to 800. The statistical analysis (robust Poisson regression) detected six factors associated with seropositivity, including the rainy season (prevalence ratio; PR=1.94, P=0.013), male dogs (PR=2.10, P=0.005), animals with age greater than five years (PR=4.21, P=0.012), consumption of untreated water (PR=1.87, P=0.043), free access of dogs to street (PR=2.15, P=0.011) and contact with wildlife (PR=3.54, P=0.050). The serogroup Icterohaemorrhagiae has a high zoonotic potential and was the most frequent in seropositive animals. The high real prevalence of Leptospira spp. in a transmission region of the semiarid region of Paraíba and the occurrence of seroreactive animals in all the counties suggest wide distribution of the infection and reinforce the need for preventive measures to avoid infection in pets and, consequently, to humans. The analysis of factors associated with the prevalence suggest greater manegment cares with the dogs.

ABSTRACT Purpose: Interaction through the use of social media, smartphones, and online games is increasingly growing. Regarding games, it is estimated that part of the population spends more than 12 hours a week in interactions provided by online games. In this context, the objective of the present research is to study and deepen the connection between co-creation and gamification applied to the services sector. Originality/value: This research aims to contribute to the gap reduction in the existing literature in the areas of gamification and co-creation applied to the services sector. The fact that the research is applied to a peripheral region of Europe and to a different business sector contributes to a better understanding of the relationship established between gamified co-creation and the business sector in these types of regions. It also helps companies in the process of developing and implementing new strategies. Design/methodology/approach: By using a qualitative methodology, seven interviews were carried out in different companies located in Portugal and operating in the services sector. Findings: This research will allow a better understanding of the Portuguese business world and if this corporate environment is ready to work with new methodologies. It was possible to point out some good practices related to the implementation of a gamified co-creation methodology, as well as to provide an alert for the negative aspects that may arise when working under this approach. Companies acknowledge that the adoption of a gamified co-creation methodology brings some advantages and increases their competitiveness levels in the market.

Hierarchy and collaborative networks: a study on the colour of culture
Authors: Milagres Rosileia das Mercês , Silva Samuel Araujo Gomes da , Rezende Otavio
Published: June 2021

Abstract Some theorists argue that collaborative networks are self-regulated structures, and their coordination strategy must be essentially horizontal and shaded by a “hierarchy.” In contrast, others assume that structuring of coordination processes and the establishment of roles is considered to be necessary to achieve the desired results that hierarchise relationships between different actors. Based on this apparent counterpoint, this article is dedicated to understanding the coordination structure of The Colour of Culture (A Cor da Cultura - ACDC) network. Specifically, we are guided by these questions: Can ACDC be characterised as a self-regulated network or as a hierarchical arrangement? What are the functions/dysfunctions of the network’s coordination elements on the ACDC network? The operationalisation of the research relied on the use of primary and secondary data: coded, categorised, and classified using the thematic content analysis technique. The results of the case study indicate how the coordination instruments adopted led some to view the ACDC network as a hierarchical arrangement. However, there are indications that it was the adoption of these instruments that facilitated the achievement of these results. That is, the case demonstrates the possibility of coexistence between a network and hierarchical coordination mechanisms.

Abstract The offer of business process modeling methodologies is quite extensive, making it difficult for scholars in the BPM area to choose properly. In this context, this paper has the objective to present the main modeling methodologies, with applications, examples and comparisons. A systematic bibliographic survey and the comparative analysis of these notations used in the implementation of BPM projects have been carried out. According to the bibliometric analysis, the modeling notations of the business process most portrayed in the works surveyed are: BPMN, UML, EPC and IDEF. From the construction of a consistent overview that allows the comparative analysis of the methodologies, in order to select the one that suits better its specificities it can be verified that, although they share the same objective, each notation has its specific characteristics. This study has the main purpose of providing a basis for the adequate indication of the application of studies in the field, especially those destined for papers, dissertations and theses.
O Jovem ‘Sem Qualidades’ e o Desejo de Fascismo: enlaces entre psicanálise, educação e política
Authors: Gurski Rose , Perrone Cláudia Maria
Published: June 2021

Resumo: Este artigo realiza uma leitura sobre a construção da adolescência que vive atmosferas sociais totalitárias, através da análise das variáveis sócio-políticas presentes no romance de formação O Jovem Törless, de Robert Musil. Na interlocução entre psicanálise, educação e política, articulamos a inquietação do autor ante a ambivalência moral de sua geração, com as propostas educacionais e políticas apresentadas aos jovens deste tempo. No romance, a noção de formação foi corroída na Modernidade e substituída pela socialização com práticas homogeneizantes e massificadoras. Diante da adolescência sem qualidades, cabe um trabalho de restauração do desejo, forjando uma versão singular do destino do corpo político do sujeito e do social.

Published: June 2021

En su obra La Crisis de la Educación (1954), Hannah Arendt ya planteaba la necesidad de reflexionar acerca de la autoridad del adulto y el lugar de los adolescentes librados a sí mismos. El texto que proponemos pretende esbozar, entre dos orillas, Brasil y España, las palabras, los actos y las puestas en escena de las adolescencias confinadas en nuestras ciudades. El objetivo es poder formular nuevas preguntas, en tiempos de excesivas respuestas, en torno a los abandonos, la protección, la ausencia y la presencia del adulto en las vidas adolescentes, el papel de la educación pública y la atención clínica. Para ello, intentamos, en el marco de una investigación en curso, dar la palabra a adolescentes en diferentes situaciones sociales.

Resumo: A tradicional aliança entre educação e trabalho vem-se configurando numa aparente adesão das práticas educativas às engrenagens do capitalismo. Partindo da análise dos efeitos da entrada dessa configuração discursiva no espaço escolar, problematiza-se a hipótese da transição de um modelo educativo fundamentado numa formação cultural, tal como discutida por Adorno, em direção ao que entendemos como formação profissional. Segue-se a apresentação de uma pesquisa-intervenção no contexto de uma oficina de fotografias, cujos resultados apontam para o potencial da arte em subverter a lógica do ensino tecnicista, criando outro cenário de encontro da experiência educativa com a cidade, para além do norteado pela inserção no mercado do trabalho.

ABSTRACT Gerbera is a flowering species with relevance to the cut flower market. Understanding nutritional requirements of the species is important to improve fertilization procedures. In the present work, our objective was to evaluate the influence of different doses of nitrogen (N) and calcium (Ca) on the growth and development of gerbera cultivated in pots as a cut flower. The experiment was conducted in a protected environment in a bifactorial design, with an additional treatment consisting of the combination of three N (0.07, 0.15 and 0.2 g L-1 substrate) and Ca (0.02, 0.03 and 0.04 g L-1 substrate) doses applied every 15 days. Control plants were not supplemented with either N or Ca. No significant interaction between N and Ca doses was observed. The highest number of flower stalks was obtained with 0.15 g N L-1 substrate and 0.04 g Ca L-1 substrate. Flower diameter, plant leaf area and total chlorophyll contents were at a maximum of 0.14 g N L-1 substrate and 0.04 g Ca L-1 substrate. N and Ca doses influenced in an independent manner the growth and development of gerberas as a cut flower cultivated in pots, and we determined that its fertilization should occur every 15 days with 0.34 g N L-1 substrate and 0.04 g Ca L-1 substrate.

Abstract Flowers have received special attention not only for their ornamental nature but also for their nutraceutical, cosmetic, aromatic, and culinary properties. This study aimed to characterize physicochemical attributes and the antioxidant capacity of flowers of four gladiolus cultivars. The cultivars used were White Friendship, Rose Supreme, Jester, and T704. We analyzed the content of total soluble solids (SS), total titratable acidity (TA), SS/TA ratio, pH, vitamin C, anthocyanin, flavonoids, total phenolic compounds (TPC), total antioxidant activity (TAA), and the relationship of TPC with flavonoids and TAA for each cultivar. The results showed that the Jester flowers had the lowest TA and highest SS/TA ratio, indicating the best flavor. Jester also had the highest flavonoid content, similarly to the White Friendship and Rose Supreme. As a result, these cultivars have flowers with higher TPC and TAA content than T704. The anthocyanin content was the characteristic attribute of cultivar T704, due to its purple pigmentation. Gladiolus flowers, traditionally used in landscaping and as cut flowers, have the potential for use in human nutrition, particularly the White Friendship, Rose Supreme, and Jester cultivars.
IGREJA COMO PARTIDO a relação entre a Igreja Universal do Reino de Deus e o Republicanos
Authors: Cerqueira Claudia

Como a organização partidária do Republicanos reflete a relação da Igreja Universal do Reino de Deus (IURD) sobre o partido? A IURD foi a primeira igreja pentecostal a lançar seus próprios candidatos oficiais – inicialmente em partidos diversos, até o surgimento do Republicano que, desde sua criação, é sondado como sendo o partido da igreja. Nesta pesquisa apresento evidências que formalizam a relação entre as instituições a partir de duas hipóteses: 1) a coalizão dominante do Republicanos é composta pela cúpula da igreja; e 2) a estrutura composta por comissões provisórias (CPs) reforça concentração de poder da coalizão dominante. A análise está dividida em duas partes: na primeira parte descrevo a atuação política da IURD, enquanto na segunda apresento a organização partidária do Republicanos. Como principais resultados, destaco como a organização do partido garante o controle da igreja sobre o Republicanos, a partir dos seguintes mecanismos: com a ampla utilização de comissões provisórias no lugar de diretórios, a igreja evita a formação de lideranças locais “de fora”, enquanto a cúpula do partido, predominantemente composta por indivíduos ligados à IURD, garante aos membros da igreja poder na tomada de decisão do partido.

Abstract Introduction: Hemodialysis (HD) sessions associated with the chronic kidney disease (CKD) repercussions may cause respiratory muscle impairment and limitations of daily living activities, which may compromise the quality of life. Objective: To evaluate respiratory muscle strength and quality of life in HD patients. Methods: A cross-sectional study involving CKD patients of both sexes undergoing HD. All were evaluated during HD, using an evaluation form containing personal and clinical data, presence of comorbidities, lifestyle (including self-reported physical activity) and vital signs. Respiratory muscle strength was analyzed by maximum inspiratory (MIP) and maximum expiratory (MEP) pressures by manovacuometer and quality of life using the SF-36 questionnaire. Results: Sixty-eight patients were evaluated (69.1% men), with a mean age of 54.9 ± 13.6 years. The MEP% was below of predicted (79.5 ± 25.7) and the MIP% was reduced only in women (77.8 ± 38.7). The MIP% was related to CKD time (p = 0.04) in men. The SF-36 domain that showed the most impairment was physical limitation [25.0 (13.0-67.0)], while mental health was the least impaired domain [72.0 (62.0-84.0)]. Those who reported the practice of physical activity obtained better results in vitality domain (p = 0.01). In the analysis stratified by sex, the functional capacity domain was less compromised in men who practiced self-reported physical activity (p = 0.02). Conclusion: CKD patients undergoing HD had a reduction in MEP relative to predicted, in addition to a greater impairment of MIP in men with longer CKD time and in women alone, although the clinical relevance of this finding is uncertain. Quality of life was more compromised in the physical limitation domain, where those who self-reported physical activity achieved better results in the domains of vitality (total sample) and functional capacity (men).
Vulnerabilidade domiciliar em situação de intermitência no abastecimento de água
Authors: Diniz Tibério Gomes , Grande Maria Helena Del , Galvão Carlos de Oliveira
Published: June 2021

RESUMO Os sistemas de abastecimento em regime de intermitência fornecem água aos usuários por um período limitado de tempo, produzindo efeitos adversos à rede de abastecimento de água e aos usuários do sistema, em especial os usuários domésticos, cuja demanda é pouco flexível e a capacidade de adaptação limitada. Neste trabalho é proposto um conjunto simplificado de indicadores que permite identificar diferentes níveis de vulnerabilidade ao desabastecimento de água aos quais uma população urbana está sujeita em situação de intermitência no abastecimento. Os indicadores podem ser obtidos de dados censitários, de informações topológicas, topográficas e hidráulicas do sistema de abastecimento e de levantamentos cadastrais ou de sensoriamento remoto da localidade, podendo ser processados em Sistemas de Informações Geográficas (SIGs). Os indicadores são aplicados ao caso de Campina Grande, Paraíba, com base em levantamentos disponíveis sobre usuários que vivenciaram a situação de intermitência no abastecimento. Os resultados permitem a identificação das áreas cujos usuários podem ser potencialmente mais afetados pela intermitência no abastecimento e a recomendação de medidas mitigadoras para a redução de sua vulnerabilidade.

RESUMO O objetivo deste estudo foi caracterizar a produção de um carvão de caroço de pêssego e também avaliar a adsorção de corantes têxteis pelo carvão ativado de caroço de pêssego. A ativação do carvão foi realizada utilizando cloreto de zinco como agente oxidante. O carvão ativado foi então utilizado na adsorção de corantes, para posterior aplicação no tratamento de um efluente têxtil. Primeiramente, realizou-se a produção de carvão ativado com as temperaturas de 500, 700 e 900°C e tempo de carbonização de 10 15 e 20 minutos e verificou-se a remoção dos corantes preto reativo 5 e azul de metileno. De acordo com a metodologia de superfície de resposta, a melhor temperatura de produção apresentou-se acima de 700°C com tempo de exposição de 10 minutos para os dois corantes. Desse carvão ativado, avaliaram-se os dados de densidade, teor de umidade e cinzas, pH e rendimento. Também foram realizados ensaios cinéticos e de equilíbrio. Os dados foram ajustados a três modelos cinéticos. As medidas para determinação da eficiência na remoção de cor do efluente têxtil foram realizadas pelo método espectrofotométrico e demonstraram média de remoção superior a 62% da cor presente no efluente bruto. Desse modo, o caroço de pêssego demonstrou elevado potencial para a produção de carvão ativado visando o tratamento de efluentes contendo corantes, podendo servir como alternativa de baixo custo.

ABSTRACT: This paper analyzes the structural behavior of reinforced concrete pile caps as onshore wind turbine foundations using eight models based on the finite element method (FEM). The variables adopted are: the type of finite element utilized; the soil representation; and, considering or not the soil under the pile cap base. All materials constituting the models were considered as linear elastic behavior. The results of interest are: reaction in piles; dividing the load between soil and piles; pile cap displacement; normal radial stress and bending moments in the pile cap. The models designed on solid elements and shell elements demonstrated good compatibility between the found values, such as dividing the load between soil and piles. In some models, the numerical analysis showed results against the structural safety of the foundation when the soil under the pile cap is not considered.

Abstract Research on behavior of flat slabs under punching shear, performed by Kinnunen, Regan and Muttoni influenced the main design recommendations. Meanwhile, studies about strut and tie model developed by Schlaich for beams, deep beams and corbels also influenced these design codes. This work aimed to adapt the strut and tie model for the punching shear resistance analysis in flat slabs. The punching shear resistance of 30 flat slabs verified through strut and tie model was compared to the one designed following Brazilian, American and European codes recommendation. Subsequently, this same model was validated by comparing the test results of 32 flat slabs. The strut and tie model results, when compared with the test results, showed a better average than those from codes, and the modified strut and tie model can become an alternative for punching shear strength prediction.
Flexure shear capacity of prestressed hollow core slabs
Authors: Catoia Bruna , Rocha Arthur Lima , Ferreira Marcelo de Araújo
Published: June 2021

ABSTRACT: Provided that the anchorage capacity is guaranteed at the supports, the bearing capacity of hollow core slabs depends on the shear capacity of the pretensioned concrete webs, wherein the critical section is in a region between h and 2h from the support. For line loads acting within 2h to 6h from the supports, especially for shallow slabs 150 to 200 mm deep, it is likely to have flexure-shear cracks within the transfer region, wherein the bearing capacity is highly affected by the actual prestressing forces at the critical section. Therefore, one of the major questions pondered by structural engineers is to determine the effective amount of prestressing force that affects the shear resistance mechanism near to the support. According to ABNT NBR 14861:2011, the shear capacity is based on the flexure-shear mechanism, wherein the shear strength is a sum of the tensile concrete strength in the slab webs plus the contribution of the prestressing forces at the critical section, wherein a coefficient of 0.15 is considered. However, in both codes NBR 14861 and NBR 6118 it is required that this coefficient 0.15 should be further multiplied by an additional reduction factor in order to take into account the effect of the transmission length near to the support. Considering the current revision of the NBR 14861, this paper presents a theoretical-experimental comparison from standard shear tests of hollow core slabs with nominal depths from 150 to 200 mm carried out in different research at NETPre-UFSCar. Based on the analytical study of each term of the equation for the flexure-shear capacity, it has been observed that the coefficient 0.15 provides a conservative limit for the contribution of the actual prestressing force. Therefore, there is no need to apply any additional reduction factor in order to guarantee a safe design limit for the shear capacity.
