Abstract The article presents the conception of an acoustic project for a new opera house, called “O Guarani”, to be implemented at the federal capital, Brasília, with about 1000 seats. The main focus of the article is the acoustic conditioning of the opera house. Initially, the basic assumptions from the acoustical point of view that an opera house demands are discussed. The main constraints, such as reverberation time, must take into account both music and speech which is a typical characteristic for a room of this kind. Once the architectural concept and the materials to be used have been defined, a computational simulation is carried out, aiming to determine acoustic quality parameters, such as T20, C80 and D50, for receivers distributed in the audience. These parameters proved to be satisfactory for the intended use of the proposed theater. An auralization is then conducted. This is prepared for an aria of the opera “Don Giovanni”, by Mozart, from an anechoic recording of a soprano, interpreting D. Elvira, and ten accompanying musical instruments. The result of the auralization - available at a link - seems to show the good sound quality obtained by the proposed acoustic project.

Resumo O artigo apresenta a concepção de um projeto acústico para uma nova casa de ópera, denominada “O Guarani”, a ser implantada na capital federal, Brasília, com cerca de 1000 assentos. O foco principal do artigo é o condicionamento acústico da casa de ópera. São discutidos, inicialmente, os pressupostos básicos do ponto de escuta acústico que uma casa de ópera demanda. Os principais condicionantes, como o tempo de reverberação, devem contemplar tanto a música como a fala, o que é uma característica típica de uma casa do gênero. Definidos os materiais a serem utilizados e a concepção arquitetônica, parte-se, em seguida, para uma simulação computacional acústica, visando a determinação de parâmetros de qualidade acústica, como T 20, C 80 e D 50, para receptores distribuídos na plateia e balcões. Esses parâmetros se mostraram satisfatórios para o uso a que se destina o teatro proposto. Na sequência, é elaborada uma aurilização. Esta é preparada para uma ária da ópera “Don Giovanni”, de Mozart, a partir de uma gravação anecoica de uma soprano, interpretando o personagem D. Elvira, e dez instrumentos musicais acompanhantes. O resultado da aurilização - disponível em um link - parece evidenciar a boa qualidade sonora obtida pelo projeto acústico proposto.

Abstract: In this research, we address the composer classification supervised problem from a Natural Language Processing perspective. Starting from digital symbolic music files, we build two representations: a class representation and other based on MIDI pitches. We use the technique of n-grams to build feature vectors of musical compositions based on their harmonic content. For this, we extract n-grams of size 1 to 4 in harmonic direction, differentiating between all possible subsets of instruments. We populate a term-frequency matrix with the vectors of compositions and we classify by the means of Support Vector Machines (SVM) classifier. Different classification models are evaluated, e.g., using feature filters and varying hyperparameters such as TF-IDF formula, among others. The results obtained show that n-grams based on MIDI pitches perform slightly better than n-grams based on class representation in terms of overall results, but the best result of each one of these representations is identical. Some of our best models reach accuracy results that exceed previous state of the art results based on a well-known dataset composed of string quartets by Haydn and Mozart.

ABSTRACT Luis Tavares revolutionized cardiac surgery, always bringing the most modern instruments and equipment from his travels to England - surgical forceps, scissors, scalpels, etc. He always insisted that he was not just a thoracic surgeon, for his work extended over a wide field and created three important cardiac surgery centers which promoted a great development of cardiology. He carried out the first open heart surgery (atrial septal defect) employing extracorporeal circulation and closure of a ventricular septal defect with deep surface hypothermia of north and northeast Brazil. He promoted an intense scientific exchange program between Recife and England, resulting in significant advances in medicine, and participated directly in the creation of HEMOPE), leading to radical changes and improvements in blood therapy in the whole country. The PROCAPE, inaugurated in 2006, was the result of the cardiac center created by him in early 1970 at Hospital Oswaldo Cruz and can be considered the second largest public-university cardiology center in Brazil. He is thus widely regarded as an outstanding name in medicine in the 20th century and one of the fathers of modern cardiac surgery in Brazil. forceps scissors scalpels etc surgeon atrial Brazil HEMOPE, HEMOPE , HEMOPE) country PROCAPE 2006 197 publicuniversity public university th 200 19 20 1 2

Its purpose is to expose the intellectual path that has been followed to compose a class of literature. We start from the methodological proposal of Fernando Lázaro Carreter and Evaristo Correa Calderón in Cómo se comenta un texto literario (1968) and the ideas developed by Daniel Barenboim in Music Quickens Time (2008) to propose a class of literature that incorporates music and helps to realize how musical reflection can help to read and awaken sensitivity towards a text, its characters and the conflict it raises.

The worldwide emergence of viral diseases such as Zika, Dengue, Chikungunya, West Nile and Yellow Fever urge the search for solutions to eliminate their common vector, the Aedes aegypti mosquito. This paper describes the quantitative structure-activity relationship (QSAR) and docking studies of a series of nine 3-(3-aryl-1,2,4-oxadiazol-5-yl)propionic acids (AOPA), 1-9, previously published by our group. Additionally, three new 1,2,4-oxadiazoles, 10-12, have also been synthesized, characterized and studied. The QSAR and docking studies of all compounds, 1-12, clearly indicate that larger hydrophobic substituents such as biphenyl groups attached on position 3 in 1,2,4-oxadiazoles improve the larvicidal activity. It is worthwhile to mention that nanocapsulation of compounds 10-12 were necessary to help their dissolution in water and these three new 1,2,4-oxadiazoles also exhibited approximately equal or higher larvicidal activities compared to the former prototypes at stage L4.

Abstract: Introduction: During the Sars-CoV-2 pandemic, social distancing measures and various other stress factors may have been responsible for impacts on medical students’ mental health. Objective: The purpose of this study is to describe the mental health status of medical students at a college in northeastern Brazil, in the context of the COVID-19 pandemic, investigate symptoms of anxiety and depression, and assess resilience, as well as its possible associated factors. Methodology: A cross-sectional qualitative and quantitative method was used. Data were collected using an online questionnaire among students enrolled in the medical school; data were further processed using quantitative and qualitative statistical analysis separately. The following scales were applied: Generalized Anxiety Disorder Screener (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Wagnild and Young’s Resilience Scale (RS-25). Results: About one-third of the students lived with moderate or severe anxiety symptoms, almost half had moderate to severe depressive symptoms, and more than half were classified as having low or moderately low resilience. Conclusion: Our findings highlight the difficulty in maintaining high levels of resilience and that the presence of depression or anxiety would be related to lower resilience scores in medical students during remote education. Further studies are needed to establish a causal link with the pandemic.

ABSTRACT Objective: To determine the clinical profile of COVID-19 inpatients who were vaccinated prior to hospitalization and to compare the risk factors for death and the 28-day survival rate of between those inpatients vaccinated with one, two, or three doses and unvaccinated COVID-19 inpatients. Methods: This was a retrospective observational cohort study involving COVID-19 patients admitted to a referral hospital in the city of Recife, Brazil, between July of 2020 and June of 2022. Results: The sample comprised 1,921 inpatients, 996 of whom (50.8%) were vaccinated prior to hospitalization. After adjusting the mortality risk for vaccinated patients, those undergoing invasive mechanical ventilation (IMV) had the highest mortality risk (adjusted OR [aOR] = 7.4; 95% CI, 3.8-14.1; p < 0.001), followed by patients > 80 years of age (aOR = 7.3; 95% CI, 3.4-15.4; p < 0.001), and those needing vasopressors (aOR = 5.6; 95% CI, 2.9-10.9; p < 0.001). After adjusting the mortality risk for all patients, having received three vaccine doses (aOR = 0.06; 95% CI, 0.03-0.11; p < 0.001) was the most important protective factor against death. There were progressive benefits of vaccination, reducing the frequency of ICU admissions, use for IMV, and death (respectively, from 44.9%, 39.0% and 39.9% after the first dose to 16.7%, 6.2% and 4.4% after the third dose), as well as significant improvements in survival after each subsequent dose (p < 0.001). Conclusions: Vaccines were effective in reducing illness severity and death in this cohort of COVID-19 inpatients, and the administration of additional doses conferred them with accumulative vaccine protection.

RESUMO Objetivo: Traçar o perfil clínico de pacientes internados com COVID-19 que haviam sido vacinados antes da hospitalização e comparar os fatores de risco para óbito e a taxa de sobrevida em 28 dias entre esses internados vacinados com uma, duas ou três doses e pacientes internados com COVID-19 não vacinados. Métodos: Estudo de coorte observacional retrospectivo envolvendo pacientes com COVID-19 internados em um hospital de referência na cidade do Recife (PE) entre julho de 2020 e junho de 2022. Resultados: A amostra foi composta por 1.921 pacientes internados, dos quais 996 (50,8%) haviam sido vacinados antes da hospitalização. Após ajuste do risco de mortalidade para os pacientes vacinados, aqueles submetidos à ventilação mecânica invasiva (VMI) apresentaram o maior risco de mortalidade (OR ajustada [ORa] = 7,4; IC95%: 3,8-14,1; p < 0,001), seguidos pelos pacientes > 80 anos (ORa = 7,3; IC95%: 3,4-15,4; p < 0,001) e aqueles que necessitam de vasopressores (ORa = 5,6; IC95%: 2,9-10,9; p < 0,001). Após ajuste do risco de mortalidade para todos os pacientes, o recebimento de três doses de vacina (ORa = 0,06; IC95%: 0,03-0,11; p < 0,001) foi o fator de proteção mais importante contra o óbito. Houve benefícios progressivos da vacinação, com redução da frequência de internações em UTI, de uso de VMI e de óbitos (de 44,9%, 39,0% e 39,9% após a primeira dose para 16,7%, 6,2% e 4,4% após a terceira dose, respectivamente), bem como melhora significativa na sobrevida após cada dose subsequente (p < 0,001). Conclusões: As vacinas foram efetivas na redução da gravidade da doença e dos óbitos nesta coorte de pacientes internados com COVID-19, e a aplicação de doses adicionais conferiu-lhes proteção vacinal cumulativa.

Biochar from slow pyrolysis under controlled conditions is favorable in the transformation of waste into materials that serve as soil conditioners, and/or environmental remediation. Thus, this work aimed to produce and characterize biochar from cassava waste under different temperature conditions and evaluate interactions with Ca2+ and Pb2+ for agricultural and environmental applications. To investigate the efficiency of the interaction of biochar with nutrients (Ca) and contaminants (Pb), the influence of pH and contact time were evaluated. There was an increase in pH, pHzpc (zero point charge), and condensed aromatic structures in BC, due to the increase in pyrolysis temperature. Also, biochar demonstrated a Pb2+ adsorbed amount of 2.03 to 2.37 mg g-1 and a Ca2+ release capacity of 0.655 to 0.765 mg g-1. In this way, biochar produced from residues of cassava waste can be a viable strategy to enhance agricultural production and reduce environmental contaminants.

Resumo Em 1924, um personagem despontou na imprensa brasileira: o “Professor Mozart”. Seu nome era Mozart Dias Teixeira e, durante as décadas de 1920 e 1930, ele praticou curas em diversas cidades do país, provocando controvérsias entre setores da sociedade. O artigo analisa o caso, dividindo-se em três eixos: introduz o personagem e o debate sobre os seus métodos de cura, mostra como as polêmicas inspiraram produções artísticas que transitaram no seio da população e, por fim, discute a questão do charlatanismo e o problema da liberdade profissional e de culto. O estudo pretende ser uma contribuição à historiografia do espiritismo, do ocultismo e das ciências psíquicas no Brasil.

Abstract In 1924, a new figure appeared on the pages of Brazilian newspapers: “Professor Mozart.” In the 1920s and 1930s, Mozart Dias Teixeira practiced healing in several Brazilian cities, sparking controversy among certain segments of society. A threefold analysis of the case is presented: describing the man himself and the debate surrounding his healing methods; showing how the controversies inspired the production and circulation of art among the population; and discussing the issues of charlatanism and professional and religious freedom. The study intends to contribute to the historiography on spiritism, occultism, and psychic sciences in Brazil.

Abstract The rise of written / printed culture is, without question, one of the most significant events set forth by the beginning of Modernity. Consolidated throughout the 19th century, it brought about a series of new cultural practices that would substantially modify the way we understand the world and communicate with the other, while also providing us with a great diversity of reading practices and materials. During the 19th century, the written word began to address various specific types of population; such is the case of Diario de los Niños (1839-1840) and Los niños pintados por ellos mismos (1843) periodical publications for children which emerged under the initiative of Vicente García Torres, with the objective of contributing to the education of the future citizens required by the new project of society. This text studies these publications through the following axes: a) the first periodical publication aimed at children; b) exemplary models or Mozart for children; c) social representations around childhood.

Resumen Entre los eventos más significativos que la modernidad impulsó está el auge de la cultura escrita/impresa, cuya consolidación en el curso del siglo XIX trajo consigo nuevas prácticas culturales que modificarían sustancialmente la forma de entender el mundo y de comunicarse con el otro, y que revelarían una gran diversidad de prácticas lectoras y de materiales. El siglo XIX comenzó a dirigirse a diversos tipos específicos de población; en este contexto surgieron El Diario de los Niños (1839-1840) y Los niños pintados por ellos mismos (1843), ambas publicaciones debidas a la iniciativa de Vicente García Torres, con el propósito de contribuir a la formación de los futuros ciudadanos que el nuevo proyecto de sociedad requería. Este texto estudia dichas publicaciones a través de los siguientes ejes: a) la primera publicación periódica dirigida a la niñez; b) modelos ejemplares o Mozart para niños; c) representaciones sociales en torno a la niñez.

Considering the bicentenary of Brazil’s Independence in 2022 and that this year was proclaimed by UNESCO as the International Year of Basic Sciences for Sustainable Development, in mid-2021 the Brazilian Chemical Society (SBQ) launched the “Post 2022 Chemistry Movement - Sustainability and Sovereignty”, with the main goal of promoting different activities so that chemistry contributes for the sustainable development and sovereignty of Brazil in the coming years. One of these activities is the proposal of an action plan, with goals to be achieved by 2030 and 2050. This article describes in detail how this action plan was formulated by a working group, with the help of an advisory council and interviews of 18 professionals from universities, the government, industries, the third sector and other organizations. Mimicking the Agenda 2030 SDGs, the resulting action plan is based on two broad Chemistry Sustainable Development Goals: promoting sustainability through chemistry in basic education, and promoting sustainability in the industry and university through science, technology, innovation, and education (STI&E) in chemistry. After the definition of three driving technological challenges in STI&E, they shall be successively implemented through different actions starting in 2023 yet.

Abstract Introduction Burnout syndrome is highly prevalent among medical students. Whereas burnout syndrome has been associated with negative outcomes, like suicidal ideation, protective factors are still unknown. Objective To evaluate if there is an association between burnout syndrome and resilience in medical students, assessing covariates such as depressive symptoms, suicidal ideation, and religiosity. Method This cross-sectional study was carried out with a sample of 209 students from a medical school in Brazil. Burnout syndrome was assessed using the Maslach Burnout Inventory – Student Survey. Potential protective factors and aggravators to burnout syndrome were investigated using appropriate scales. Results Fifty-nine students (28.2%) presented burnout. Multivariate analysis showed that resilience was a protective factor (p < 0.001), along with being older, married or having better academic performance. Depressive symptoms were positively associated with burnout. Religiosity was not a protective factor and suicidal ideation was not associated with burnout when adjusted for depressive symptoms. Conclusion Burnout is frequent among medical students, impacting mental health and academic performance. Resilience seems to be a protective factor, and the relationship between burnout and suicidal ideation is possibly mediated by depressive symptoms. Prospective studies are needed to further investigate the associations found in this study.

Resumo Esse estudo faz uma análise estatística multivariada de componentes principais (ACP) para estabelecer padrões de desempenho escolar para o 5° e o 9° ano do Ensino Fundamental das escolas municipais de Ribeirão Preto. As equações matemáticas obtidas de gráficos bidimensionais de ACP revelam que os percentuais de alunos com aprendizado adequado em língua portuguesa e em matemática são os indicadores mais significativos para explicar tais padrões de desempenho. A partir dessa análise, foi possível estabelecer vetores de desempenho escolar para cada uma das escolas dos dois anos escolares do Ensino Fundamental aqui considerados.

Abstract This study performs a multivariate statistical analysis of principal components (PCA) to establish school performance standards for the 5th and 9th grades of the municipal schools in Ribeirão Preto. The mathematical equations obtained from two-dimensional PCA graphs reveal that the percentages of students with adequate learning in Portuguese language and mathematics are the most significant indicators to explain such performance patterns. From this analysis, it was possible to establish school performance vectors for each of the schools in the two elementary school years considered here. Finally, it was possible to establish a quantitative indicator of the heterogeneity for each of the school levels investigated.

Resumen Este estudio realiza un análisis estadístico multivariado de componentes principales (ACP) para establecer estándares de desempeño escolar para los grados 5º y 9º de la escuela primaria en las escuelas municipales de Ribeirão Preto. Las ecuaciones matemáticas obtenidas de los gráficos bidimensionales de ACP_revelan que los porcentajes de estudiantes con un aprendizaje adecuado en portugués y en matemáticas son los indicadores más significativos para explicar dichos patrones de desempeño.. A partir de este análisis, fue posible establecer vectores de desempeño escolar para cada una de las escuelas de los dos años de Educación Primaria aquí considerados. Esto permitió la construcción de un indicador de heterogeneidad para las escuelas del sistema municipal de Educación de Ribeirão Preto.
