A soberania da natureza na contística de Horacio Quiroga: diálogos entre teoria e ensino de literatura nas aulas de espanhol como língua adicional no Brasil

IX Congresso Brasileiro de Hispanistas realizado nos dias 22 a 25 agosto 2016Este trabalho propõe um estudo da contística do escritor uruguaio Horacio Quiroga, visando observar a soberania das forças da natureza na constituição dos personagens, levando em conta o espaço dos fatos narrados. Tal característica da narrativa quiroguiana se dá em embates entre o esforço humano pela vida e as contingências da natureza que conduzem à morte, principalmente nos contos que têm a selva como cenário, mas não apenas nestes. Para tanto, as obras Contos de amor, de loucura e de morte, publicada em 1917 pela Cooperativa Editorial Buenos Aires, e Vozes da selva (nove contos escolhidos por Pablo Rocca) foram escolhidas como corpus. Além disso, buscar- seão aproximações entre teoria e ensino de literatura nas aulas de espanhol como língua adicional no Brasil.UNILA­-UNIOEST

Transporte sedimentar de misturas arenosas em ambientes costeiros

Sediment dynamics is a complex subject, playing an important role in coastal areas. The interaction between the wave action and sediment particles is determinant to understand sediment transport. The knowledge of sediment transport in sand mixtures is relevant as the coastal zone usually presents large heterogeneities of sediment particles sizes in the horizontal and vertical directions, which denote the existence of selective transport process. The goal of the present study was to understand selective sand transport mechanisms associated with wave-dominated conditions. To achieve the proposed objective, the work was supported by several approaches to give insights into the processes associated with heterometric sediment transport. The first approach consisted in a review of the literature to understand what is known and the lack of knowledge in the subject. The second approach consisted in performing a set of experiments with fluorescent sand tracers in natural conditions, at the field, and in a controlled environment, at the laboratory. The experiment conducted at Patos beach, Spain, aimed to observe the behavior of the native sand in the natural environment. The one performed at a large wave flume (Großer Wellenkanal, GWK) in Hannover, considered distinct sediment mixtures under two wave conditions. In both, measurements of the total and fractional transport were made. Finally, a quasi-steady and a semi-unsteady model were considered to calculate the net sediment transport of a large data set, for uniform and graded sand, allowing to identify limitations of the models and to propose new methodologies to obtain more adequate results. The experimental results obtained in the field allowed to observe the tracer transport towards the beach, in the wave direction, and to characterize the transport of the different fractions of the tracer in terms of the hydrodynamic processes. The laboratory experiment allowed to verify the occurrence of interaction between the sand fractions, with the finer (coarser) sediment decreasing (increasing) their transport, as the percentage of coarse sand in the bed mixture increases. The validation of the models was conducted and their performance was improved with the introduction of parameters related to surface wave streaming effects and bedforms.A dinâmica sedimentar é um tema complexo, desempenhando um papel importante nas zonas costeiras. A interação entre a ação das ondas e as partículas de sedimento é determinante para compreender o transporte sedimentar. O conhecimento do transporte de sedimentos heterométricos é relevante uma vez que a zona costeira apresenta geralmente grandes heterogeneidades na dimensão das partículas sedimentares nas direções horizontal e vertical, o que denota a existência de processos seletivos de transporte. O presente estudo teve como objetivo compreender os mecanismos de transporte seletivo de areia associados a condições hidrodinâmicas dominadas pelas ondas e considerou diferentes abordagens para evidenciar os processos que intervêm no transporte de sedimentos heterométricos. A primeira abordagem consistiu numa revisão da literatura para compreender o conhecimento atual e as lacunas existentes. A segunda abordagem consistiu na realização de um conjunto de experiências com traçadores de areia fluorescente em condições naturais, no campo, e em ambiente controlado, no laboratório. A experiência realizada na praia de Patos, Espanha, visou observar o comportamento da areia nativa em ambiente natural. A experiência realizada no grande canal de ondas (Großer Wellenkanal, GWK) em Hannover, considerou misturas de sedimentos com granulometrias distintas sob duas condições de ondas. Em ambas as experiências, foram feitas medições do transporte total e fracionado. Finalmente, um modelo quase-estacionário e um modelo semi-não estacionário foram considerados para calcular as taxas de transporte sedimentar de um grande conjunto de dados experimentais, para areia uniforme e heterométrica, permitindo identificar limitações dos modelos e propor novas metodologias para obter resultados mais adequados. Os resultados experimentais obtidos no campo permitiram observar o transporte do traçador em direcção à praia, na direcção das ondas, e caracterizar o transporte das diferentes frações do traçador em termos dos processos hidrodinâmicos. A experiência laboratorial permitiu verificar a ocorrência de processos de interação no transporte das diferentes frações de areia, com a fração mais fina do sedimento (mais grosseira) a diminuir (aumentar) o seu transporte, à medida que a percentagem de areia grosseira na mistura do leito de fundo aumenta. A validação dos modelos foi realizada e o seu desempenho foi melhorado com a introdução de parâmetros relacionados com os efeitos de streaming e formas de fundo.Programa Doutoral em Ciência, Tecnologia e Gestão do Ma

Effectiveness of physical therapy for pregnancy-related low back and/or pelvic pain after delivery: A systematic review

[EN] The aim of this work was to investigate the effectiveness of physical therapy for the treatment of low back pain (LBP) and pelvic girdle pain (PGP) related to pregnancy after delivery. A systematic review of studies published since 1985 in the databases Medline, PEDro, SciELO, SCOPUS, LILACS, and the Cochrane Library was made. Studies that focused on postpartum LBP or PGP, without being related to pregnancy or in other non-pregnant patients, were excluded, as were papers addressing LBP or PGP indicating radiculopathy, rheumatism, or any other serious disease or pathologic condition. In accordance with the exclusion criteria and duplicate articles, of the 105 articles retrieved only six were considered for quality assessment with the PEDro Scale. Among these six papers, two were follow-ups, such that only four trials were included in this review. All trials used exercise for motor control and stability of the lumbopelvic region, but with different intervention approaches. The study affording the best evidence used individual guidance and adjustments given by the physiotherapists. Nevertheless, this systematic review was inconclusive and showed that more randomized clinical trials, with good quality, are needed

Metodologia de transferência tecnológica de baixa complexidade

Trabalho apresentado no 31º SEURS - Seminário de Extensão Universitária da Região Sul, realizado em Florianópolis, SC, no período de 04 a 07 de agosto de 2013 - Universidade Federal de Santa Catarina.A política brasileira voltada para a transfêrencia tecnológica impõe de um lado a capacidade das empresas fornecedores de tecnologia em atender às demandas dos empreendimentos produtivos e por outro, a capacidade destes últimos em absorver os fluxos das tecnologias desenvolvidas. No Brasil, particularmente em regiões de baixos índices de desenvolvimento sócio-econômico, estes dois atores apresenta um elevado grau de dificuldades em se inserir nesta política por ser este um instrumento exigente quanto à formalização dos empreendimentos. Neste contexto que o Laboratório de Estamparia do Campus Araranguá/IFSC desenvolve o Programa de Transferência Tecnológica de Baixa Complexidade para a Cadeia Têxtil Local visando potencializar a cooperação cadeia de fornecedores/pequenos empreendimentos/instituição tecnológica no sul catarinense. Este artigo apresenta um estudo estabelecido com base na experiência do grupo em assessorar pequenos empreendimentos sobre a infraestrutura (força de trabalho) disponibilizada pelas empresas fornecedoras de tecnologia em estamparia localizada (transfer e sublimado) na região sul de Santa Catarina. Foi possível, assim, identificar os elementos de possível intervenção do Câmpus no objetivo de cumprir o papel de agente de interligação entre os dois extremos da questão

Videokymography assessment of vocal fold vibration before and after hydration

Keeping the body hydrated is one of the factors that contribute to organic and functional laryngeal health, especially for professional voice users. Hydration is considered an important factor for the prevention and treatment of dysphonias. There is no objective evaluation that quantifies water present in the vocal fold tissue. AIM: To evaluate changes in vocal folds investigated through videokymography after internal and external hydration of voice professionals. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: We assessed six male professional voice users after leaving the workplace (six hours) and without having drunk water for the past four hours. We conducted ENT evaluation, comprising the first laryngeal assessment with laryngoscopy with and without stroboscopic and videokymography. These people were submitted to external and internal laryngeal hydration. They drank two glasses of hydrating solution with electrolytes, Passion Fruit Flavor (total of 300 ml), at room temperature, and external hydration with inhalation of saline solution at 0.9% during 10 minutes. Using videokymography we evaluated the time of open and closed phases during phonation, defining a quotient between these two parameters. RESULTS: We found five subjects with reduced or increased quotient. CONCLUSION: Videokymography was able to detect differences at the vibrating characteristics of vocal folds before and after hydration.Manter o corpo hidratado é um dos fatores que contribuem para a saúde orgânica e funcional da laringe, principalmente nos profissionais da voz. Sabe-se que a hidratação é considerada fator muito importante na prevenção e tratamento de disfonias, porém não existem formas objetivas e não-invasivas de avaliação da quantidade de água nos tecidos da prega vocal. OBJETIVO: Avaliar as modificações na vibração da onda mucosa nas pregas vocais com o uso da videoquimografia após hidratação interna e externa em profissionais da voz. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Seis profissionais da voz, do sexo masculino, após a jornada de seis horas de trabalho sem ingestão de líquidos por um período de 4 horas, foram avaliados pelo médico otorrinolaringologista, utilizando-se a laringoscopia com e sem estroboscopia e videoquimografia. Os indivíduos foram avaliados antes e após terem sido submetidos à hidratação laríngea interna (ingestão de 300 ml de solução aquosa com eletrólitos, em temperatura ambiente) e externa (com inalação de solução salina a 0,9% durante 10 minutos). Com o uso do videoquimógrafo, avaliamos o tempo de fase aberta e fechada durante fonação fazendo um quociente entre estes dois parâmetros. RESULTADOS: Encontramos cinco indivíduos com quociente reduzido e um aumentado. CONCLUSÃO: A videoquimografia foi capaz de detectar diferenças nas características vibratórias na onda mucosa das pregas vocais após hidratação da laringe.UNIFESP-EPMUNIFESP, EPMSciEL

Social Media Advertising: Factors Influencing Consumer Ad Avoidance

Social media has become a key field for expansion of advertising. However, despite the enthusiasm of both advertisers and technology providers, intense advertising on social media may result in companies’ messages being lost amongst the ‘noise’. This has led advertisers to create more daring adverts in order to stand out. However, such ‘controversial’ adverts may, subsequently, turn consumers off, leading consumers to avoid ads. This study examines potential factors influencing consumers’ decisions to avoid controversial ads on social media. Using data on social media usage from 273 consumers, a conceptual model of social media ad avoidance antecedents was tested via structural equation modelling. The results show that perceptions of adverts as controversial result in ad avoidance, but this effect is moderated by individual factors, such as ethical judgement. These results reveal noteworthy insights that have significant theoretical and practical implications for researchers in the area, and social media marketers alike

Airway obstruction produces widespread sympathoexcitation: role of hypoxia, carotid chemoreceptors, and NTS neurotransmission

Obstructive sleep apnea (OSA) is the most common respiratory disturbance of sleep and is closely associated to cardiovascular diseases. In humans, apnea increases respiratory effort and elevates muscle sympathetic nerve activity (SNA), but the primary stimulus for the SNA activation has not been identified. We recently developed a model of apnea in rodents using acute airway obstruction. In this study, we employed this model to test whether the elevation in SNA was mediated by hypoxia, carotid chemoreceptors, or neurotransmission in the nucleus tractus solitarius (NTS). In anesthetized, male Sprague-Dawley rats, airway obstruction (20s) increased phrenic nerve activity (PNA), arterial blood pressure (ABP), and lumbar, renal, and splanchnic SNA. The changes in SNA were similar across all three sympathetic nerves. Inactivation of chemoreceptors by hyperoxia (100% O-2) or surgical denervation of carotid chemoreceptors attenuated, but did not eliminate, the changes in SNA and ABP produced by airway obstruction. To interrupt afferent information from carotid chemoreceptor and extracarotid afferents to the hindbrain, airway obstruction was performed before and after NTS microinjection of the GABA(A) agonist muscimol or a cocktail of NMDA and non-NMDA antagonists. Inhibition of NTS neurons or blockade of glutamatergic receptors attenuated the increase in lumbar SNA, splanchnic SNA, renal SNA, and PNA. Collectively, these findings suggest that PNA and SNA responses induced by airway obstruction depend, in part, on chemoreceptors afferents and glutamatergic neurotransmission in the NTS.National Heart, Lung, and Blood Institute GrantAmerican Heart Association Established Investigator AwardCoordination of Training of Higher Education Graduate Foundation (CAPES)National Council for Scientific and Technological Development (CNPq)Univ Fed Sao Paulo, Dept Physiol, Sao Paulo, SP, BrazilUniv Pittsburgh, Sch Med, Dept Med, Div Renal Electrolyte, Pittsburgh, PA 15213 USAUniv Pittsburgh, Sch Med, Hypertens Ctr, Pittsburgh, PA USAUniv Fed Sao Paulo, Dept Physiol, Sao Paulo, SP, BrazilNational Heart, Lung, and Blood Institute Grant: R01 HL113270Web of Scienc

Food waste biorefinery advocating circular economy : bioethanol and distilled beverage from sweet potato

The exponential growth rate of the global population has been causing a threat to finite resources and also increasing the amount of waste generated. The global quantitative food waste for tubers is 45% per year, which in Brazil would amount to 350,000 tons of sweet potato wasted annually. Food waste causes 10% of the emissions of greenhouse gases. In this work, food waste biorefineries are the proposed solution. Integrated processing via a combination of different technologies to produce both ethanol and distilled beverage was evaluated to valorize sweet potato waste profitably within the circular economy concept. No works concerning the integrated production of both products simulating different real market scenarios were found. Five different scenarios varying the production percentage of each product were evaluated. The higher the production of the distilled beverage, the more profitable the scenarios are. Economic results began to be positive when the production for sale of each product reaches 40%, plus 20% of ethanol for domestic consumption. The scenario with 80% of beverage production presented NPV of US$ 1,078,500.18, IRR of 51%, and discounted payback of 1.06 years. The sweet potato waste biorefinery is a sustainable model and contributes to the development of the agriculture and food sector by providing new businesses and consequent job creation. It also leads to the reduction of greenhouse emissions by producing renewable resources and marketable products, thus reaching the goals of the circular economy
