Authors: Neta I. A. Bezerra , Mota M. F. , Lira H. L. , Neves G. A. , Menezes R. R.
Published: October 2020

Abstract Titanium dioxide (TiO2) based nanostructured materials have shown great potential for use in implants thanks to their excellent physicochemical properties, such as high specific surface area, ability to elicit positive cell response, and stability in body fluids. However, there are few studies in the literature that focus on the use of nanostructured TiO2 to support cell growth and bone regeneration. The purpose of this survey is to review the state of the art of TiO2 for use in bone implants, as well as provide insight into its characteristics and synthesis methods. Studies of the biological properties of nanostructured TiO2 are described, establishing its potential for the biomedical field.
Use of calcined clay as cementitious addition in mortars to immobilize heavy metals
Authors: Souidi F. , Chelouah N. , Bouzeroura M.
Published: October 2020

Abstract The aim of this study was to examine the use of calcined clay (CC), which is a pozzolanic material, as a substitute for 10% by weight of the amount of cement, for the stabilization/solidification (S/S) of hazardous waste using a hydraulic binder. For comparison, an ordinary Portland cement was used. The standard toxicity characteristic leaching procedure (TCLP) test showed that the average concentrations of heavy metals in the raw hazardous waste far exceeded those of the required standards. Leaching of heavy metals from the mortar was evaluated by the monolithic leaching test (MLT) under dynamic leaching conditions for 64 days in sulfated and neutral media. Tests of compressive strength, setting times, and X-ray diffraction were carried out. The addition of CC considerably improved the strength of the mortar specimens containing hazardous waste. Following the MLT test, CC cement-made mortar was more efficient in the S/S of heavy metals than mortar made without CC.
A review on additive manufacturing of ceramic materials based on extrusion processes of clay pastes
Authors: Ruscitti A. , Tapia C. , Rendtorff N. M.
Published: October 2020

Abstract This paper aims to present a state of the art of additive manufacturing (AM) of ceramic materials based on extrusion processes of clay pastes, reviewing the definitions and classifications of the AM field under current international standards. A general overview on the AM category ‘material extrusion’ is provided and the class ‘paste deposition modeling’ is proposed for those techniques based on the extrusion of pastes that are solidified by solvent vaporization, with the aim of distinguishing it from the class ‘fused deposition modeling’, which is applied to extruded polymers through temperature plasticization. Based on the survey of background information on 3D printing technology by ceramic paste extrusion, a classification and historization of the innovations in the development of this technology are proposed.

Published: October 2020

Abstract CaFe2O4 nanofibers were successfully synthesized via solution blow spinning (SBS), and the influences of heat-treatment on morphological, microstructural, magnetic, and optical properties of the nanofibers were evaluated. In the synthesis process, stoichiometric amounts of iron and calcium nitrates were dissolved in an aqueous solution containing polyvinylpyrrolidone (PVP) and, after that, hybrid nanofibers (PVP/precursors) were produced by SBS. The hybrid nanofibers were calcined and then subjected to microstructural, morphological, and magnetic characterizations. The results evidenced that the fibers presented the crystalline nature of the single-phase CaFe2O4, with a crystallite size of 32.7 and 34.4 nm for the samples calcined at 800 and 1000 °C, respectively. The CaFe2O4 fibers calcined at 600 and 800 °C presented a homogeneous morphology, without beads, and mean diameters of 521 and 427 nm, respectively. The results also revealed nanofibers with low band gaps of approximately 1.98 eV and characteristics of soft magnetic materials.

Authors: Silva L. A. , Nahime B. O. , Lima E. C. , Akasaki J. L. , Reis I. C.
Published: October 2020

Abstract The X-ray diffraction (XRD) technique has been widely used in order to investigate anhydrous and hydrated cement phases. In this study, XRD was used in order to analyze the concrete floor polishing waste (CFPW) and cementitious paste containing CFPW. The diffractograms obtained were compared with literature data in order to identify the phases of analyzed materials. Rietveld refinement of XRD pattern of paste containing 12% of CFPW addition was also carried out, in order to analyze calcite and aragonite structures, as these phases are calcium carbonate polymorphs that contribute to matrix filling. XRD pattern of CFPW showed a high concentration of carbonate phases, indicating that the concrete waste was carbonated. The CFPW addition in the cementitious matrix changed the hydrate cement products, as it induced the formation of carboaluminate phases, such as hemicarbonate. Calcite, which is a stable phase, contributed better to the filler effect, as its particles have higher volume than aragonite.
Visible-light photocatalytic activity and recyclability of N-doped TiO2 films grown by MOCVD
Authors: Oliveira E. C. de , Bento R. T. , Correa O. V. , Pillis M. F.
Published: October 2020

Abstract Nitrogen-doped TiO2 films were grown on borosilicate glass substrates at 400 °C by the metallorganic chemical vapor deposition (MOCVD) for removing dye from water under visible light. The effect of N-doping on the structural, surface, and photocatalytic properties of films was evaluated. X-ray photoelectron spectroscopy (XPS) analyses revealed that 1.56 and 2.44 at% of nitrogen were incorporated into the films by varying the NH3 flux during the growth. Methyl orange dye degradation experiments showed that the N-doped films presented photoactivity under visible light. The film containing 2.44 at% of nitrogen exhibited the best photocatalytic behavior, with 55% of efficiency. Recyclability tests under visible light showed that the film efficiency dropped gradually after each test. N-TiO2 films grown by MOCVD have the potential to be used in environmental applications by removing pollutants using a green method under sunlight or even under internal illumination, although its reuse is limited.

Authors: Dantas S. L. A. , Gomes Y. F. , Lopes-Moriyama A. L. , Correa M. A. , Souza C. P.
Published: October 2020

Abstract Carbide-type ceramic materials such as nickel-doped molybdenum carbide have promising photocatalytic degradation activity. The addition of nickel to the molybdenum carbide aims to increase its reaction yield and also its characteristics. The objective of this paper was to study the photocatalytic activity of Mo2C and 5% and 10% nickel-doped Mo2C materials used for the degradation of the Maxilon Blue GRL 300 textile dye. The structural properties were characterized by X-ray diffraction and scanning electron microscopy. For the determination of band gap energy, diffuse reflectance spectroscopy was used. The samples of the photocatalysis tests were analyzed by UV-visible spectroscopy. The best reaction yield was observed for the 5% nickel-doped molybdenum carbide sample in photocatalytic tests, reaching a yield of around 92% in the final concentration of the dye solution.

Authors: Kruger P. , Kossute A. F. , Chinelatto A. S. A. , Pereira E.
Published: October 2020

Resumo Agregados reciclados possuem grande quantidade de material pulverulento em sua constituição, que em excesso causa prejuízos às propriedades de argamassas. Neste trabalho é proposto o estudo da influência do material pulverulento de agregado miúdo provindo de resíduos de construção e demolição (RCD) nas propriedades do próprio material e em argamassas. Para tanto, foi realizada a caracterização do agregado e foram adicionados teores de 0, 12%, 20% e 30% de material pulverulento de RCD às argamassas. Realizaram-se os ensaios de consistência, resistência à compressão, densidade de massa, absorção (capilaridade e imersão) e variação dimensional. Os resultados demonstraram que o material pulverulento de RCD não interferiu significativamente nas propriedades de consistência, absorção por imersão e índice de vazios para adições de até 12%. No entanto, a partir da fração limite da norma NBR 15116 de 20%, quanto maior foi o teor de material pulverulento utilizado, maior foi o prejuízo às propriedades das argamassas. Para o teor de 30% de material pulverulento, observou-se queda de 40% da resistência à compressão e aumento de 28% da absorção por imersão em relação ao teor de adição de 20%.

A psicopatologia da pandemia: literatura, ciência, política
Authors: D‘Agord Marta Regina de Leão , Lang Charles Elias , Triska Vitor Hugo Couto
Published: October 2020

O contexto da atual pandemia tanto nos remete a pestes e pragas do passado quanto nos interroga acerca das possíveis transformações sociais que serão - ou não - produzidas. Encontramos na história da literatura ocidental diversos testemunhos do impacto desses flagelos vividos pela humanidade na forma de narrativas ficcionais. Nessas, a forma metafórica redimensiona a psicopatologia diante de situações de desamparo. A modernidade ocidental também é marcada pelo discurso da ciência, seus notáveis progressos, mas também seus ideais, suas ambições e mesmo seus limites - agora reatualizados justamente quando eventos tais como a pandemia de 2020 pareciam ou ficção ou um passado já superado. Este trabalho aborda as relações entre literatura e ciência desvelando as dimensões políticas e psicopatológicas dos eventos globais relacionados à COVID-19.

Authors: ALMEIDA Alinne Paula de , FORTES Fernanda Santos , SILVEIRA Brenda Kelly Souza , REIS Nínive de Almeida , HERMSDORFf Helen Hermana Miranda
Published: October 2020

ABSTRACT Objective To assess the relationship between branched-chain amino acids intake in the current diet and the metabolic and body adiposity markers in a population at cardiovascular risk. Methods This is a cross-sectional study with 282 adults and elderly people from the Cardiovascular Health Care Program of the Universidade Federal de Viçosa. Sociodemographic, anthropometric and body composition data, as well as metabolic biomarkers were collected using standardized protocols. Dietary intake of branched amino acids was assessed using a 24-hour recall. Results Individuals with a higher branched-chain amino acids intake (≥2.6g/day, median value) had lower body fat (29.6 vs 32.2%; p=0.019), and higher serum ferritin (113.2 vs. 60.1mg/dL; p=0.006) and uric acid concentrations (4.4 vs. 4.0; p=0.023). In addition, a lower prevalence of overweight and excessive abdominal fat (p<0.05) was found in the individuals with higher branched-chain amino acids intake. They also had a higher daily intake of fiber, copper, zinc, magnesium, and iron, as well as a lower intake of total lipids. Conclusion In the present study, the intake of branched amino acids is negatively related to total and central adiposity, but more studies are needed to fully elucidate this possible relationship.

Authors: REIS Lígia Cardoso dos , JAIME Patricia Constante
Published: October 2020

ABSTRACT Objective To develop, validate and analyse intra- and inter-raters’ agreement and reliability of a scale for the evaluation of food and nutrition education practices in primary health care. Methods Three theoretical references were used for the development of items with answers on a 4-point scale (not observed, partially/satisfactorily/fully observed): the Brazilian Dietary Guidelines, the Interprofessional Collaborative Practice and the Family Health Strategy as models for organizing primary health care. The scale was submitted for content and face panel validation and it was further reevaluated online. Thirty specialists used the scale for the rating of 4 videos produced for the study showing food and nutrition education practices in primary health care settings. Intra- and inter-raters agreement and reliability were analyzed by test at one time point and retest 30 days later. Results The scale initially included 72 items but was reduced to 17 items after content and face validation, together with a fill-out manual that was reviewed by experts. In the re-evaluation, all 17 items were maintained, and content adjustments were made in the manual. Thirty raters applied the scale to the videos in the test, and 28 in the retest. All videos obtained combined kappa values of >0.4. In the test-retest, 19 raters showed >80% agreement; in the inter-rater evaluation, 14 raters generated kappa values >0.75. Conclusion The scale underwent content and face validation and showed to be useful to diagnose the absence and the full addressing of the Brazilian Dietary Guidelines content with good intra- and inter-rater agreement and reliability in different settings of Primary Health Care.

Published: October 2020

ABSTRACT Objective To describe the food environment of a public university located in the city of Rio de Janeiro, Brazil, and to review the changes that occurred between the years 2011 and 2016. Methods Time trend study (through repeated cross-sectional studies) of the sale of food, culinary preparations and beverages in the University Campus establishments in 2011, 2012 and 2016. Variables regarding the description of the establishments and the offer, price and advertising of food, beverages and culinary preparations were assessed through a checklist. Comparisons between establishments in each year and the analysis of such comparison changes during the period were performed by assessing the difference between absolute and relative values observed in each year. Results Increased number of establishments available, good convenience and financial accessibility were observed. There was a relative disadvantage in the availability of fresh or minimally processed foods and culinary preparations; a predominance of advertising of ultra-processed foods; and lack of nutritional information of culinary preparations. The predominance of establishments selling snacks and candies increased over the years. Conclusion In the period studied, the university food environment did not favor healthy food choices.

Published: October 2020

Esse artigo descreve uma proposta de atividade prática para a graduação, envolvendo um estudo teórico-experimental sobre a influência do ar no movimento de queda dos corpos. Para isso, analisou-se a dinâmica do movimento de objetos esféricos em queda vertical no ar, considerando-se a força de arrasto, apreciando-se a relação entre um intervalo de tempo característico e o comportamento da velocidade e da aceleração, comparando-se a previsão do modelo teórico com os dados experimentais. Para a obtenção dos dados, realizou-se um ensaio utilizando-se de filmagem da queda com aparelho celular e posterior tratamento com o Tracker. Os resultados apontaram que o movimento de queda de um corpo esférico de isopor com diâmetro da ordem de dois centímetros serviria ao propósito, permitindo verificar-se a presença do arrasto inercial e a tendência a uma velocidade limite em uma queda inferior a três metros, em acordo com as previsões teóricas. Além disso, verificou-se não haver correlação entre o módulo da velocidade inicial com a magnitude da velocidade terminal, implicando que a transição ocorrida do regime viscoso para o inercial, nos primeiros instantes, não afetaria o comportamento da velocidade nos instantes seguintes. Palavras-chave: Ensino de Física, queda no ar, velocidade terminal, força de arrasto, resistência do ar, viscosidade.

Published: October 2020

Abstract Objectives: to evaluate the effect of an intervention on the incidence of nipple trauma and the quality of breastfeeding technique in the first month of postpartum. Methods: this is a quasi-randomized intervention study with 180 puerperal women equally distributed between experimental and control groups. The intervention was performed at a maternity and consisted of an educational session on breastfeeding technique. A descrip-tive analysis of the groups’ characteristics was performed, comparing the frequencies of unfa-vorable parameters related to breastfeeding technique between groups. Pearson’s chi-square test and Fisher’s test were used, and p≤0.05 was adopted as the critical level of significance. Results: at 30 days, 64% and 15% of the mothers used the technique correctly, respec-tively, in the experimental and control groups with RR=4.87 (CI95%=2.93-8.34); NNT=1.96 (CI95% =1.61-2.72); p<0.001. In the experimental group, a decrease was observed in the unfavorable parameters of the breastfeeding technique (p≤0.05). The incidence of nipple trauma was 30% in the experimental group and 38.9% in the control group (p=0.21). Conclusions: the intervention was insufficient to prevent nipple trauma in the experi-mental group, but significantly improved the quality in the breastfeeding technique.

Published: October 2020

Abstract Objectives: to evaluate self-perceived body image and body satisfaction of adolescents and their associated factors. Methods: across-sectional study carried out with 200 adolescents from a non-govern-mental organization of Campinas-SP. Self-perceived body image was assessed using a scale of silhouettes and body satisfaction by body areas. Association between sociodemographic and anthropometric data and body image and satisfaction were assessed by logistic regres-sion. Results: seventy percent of normal weight boys and 88% of girls wrongly perceived their nutritional status according to the objective standards. The prevalence of body dissatisfac-tion was 76.5%. Twenty-two percent of adolescents reported dissatisfaction with their body shape. Self-perceived body image was associated with nutritional status (OR= 0.25; CI95%=0.09-0.73), abdominal obesity (Waist/Height ratio- WHR) (OR=26.57; CI95%=3.98-177.18), and gender (OR=2.65; CI95%=1.16-6.05). Conclusions: we identified an important distortion and dissatisfaction with body shape. Girls, overweight/obese adolescents and those with abdominal obesity have more chance to this condition. These findings can subsidize actions that deal with the issue of acceptance of self-image, preventing more serious disorders that may directly affect the health of young-sters.

Published: October 2020

Abstract Objectives: to identify dietary patterns (DP) and associated factors in first grade school-children in elementary schools in the South of Brazil. Methods: school-based cross-sectional study, with a non-probabilistic sample of 782 schoolchildren aged 6 to 8. Food intake was assessed by a food frequency questionnaire. DP were identified using the principal component analysis and the prevalence ratios were obtained by Poisson regression with a robust variance. Results: four DP were identified and accounted for 25.3% of the total variance: "fruit, vegetables and fish" (8.5%), "sweets and salty snacks" (7.0%), "dairy, ham and biscuits" (5.0%) and "common Brazilian food" (4.8%). After the adjustment, breakfast habit and lower frequency of meals in front of a screen increased the probability of adherence to a high consumption of DP of "fruit, vegetables and fish". The maternal schooling level was linearly and inversely associated with DP of "sweets and salty snacks" and "common Brazilian food", and positively related to the DP of "dairy, ham and biscuits". Schoolchildren with food inse-curity and sufficiently active had higher probability of adherence to DP of "common Brazilian food". Conclusions: four DP were identified and associated with food insecurity, maternal socioeconomic characteristics and schoolchildren’s behavioral characteristics.

Published: October 2020

Abstract Objectives: to evaluate factors associated with neonatal near miss and death in reference hospitals. Methods: this case-control study included 364 cases and 728 controls among 4,929 births. Cases were identified by Apgar < 7 at 5 minutes, weight < 1500 g, gestational age <32 weeks, mechanical ventilation or congenital malformation. After follow-up, outcomes were reclassified into: true controls, near miss and neonatal death. Hierarchically, variables with a p-value < 0.20 were included in the multiple logistic regression. Results: the neonatal near miss rate was 54.1 per 1,000 live births, and the near-miss-to-death ratio was 2.75. Between the control and near miss groups, the predictor variables were neonatal intensive care admission [OR = 35.6 (16.7 - 75.9)] and central venous access [OR= 74.8 (29.4 - 190.4)]. Between the control and death groups, neonatal intensive care admission [OR = 100.4 (18.8 - 537.0)] and central venous access [OR = 12.7 (3.7 - 43.2)] were significant. Between the near miss and death groups, only Apgar < 7 at 5 minutes [OR = 4.1 (1.6 - 10.6)] and vasoactive drug use [OR = 42.2 (17.1 - 104.5)] were significant. Conclusion: factors associated with a greater chance of near miss and/or neonatal death were: Apgar score <7 at 5 minutes, neonatal intensive care confinement, having central venous access, and use of vasoactive drugs.

RESUMO Este relato tem como objetivo abordar a institucionalização e a configuração atual da formação em Museologia no Brasil, tendo como ponto de partida sua origem em 1932 até seu estado atual neste século XXI. Metodologicamente, baseia-se em pesquisa de cariz bibliográfico, documental e descritiva, pautado em fontes históricas primárias e secundárias, sob análise qualitativa. Relata a formação a partir da criação do Curso de Museus do Museu Histórico Nacional, sua evolução para os cursos de graduação e, consequente, pós-graduação em Museologia, culminando nos atuais 17 cursos de graduação e seis programas de pós-graduação stricto sensu. Conclui que a formação em Museologia no Brasil é marcada por pioneirismo iniciado quando da criação do Museu Histórico Nacional em 1922 e considerável avanço, sobretudo, nos primeiros anos do século XXI. Contudo, o cenário atual de formação ainda não atinge todas as regiões do país, visto que os cursos de pós-graduação stricto sensu estão presentes em três das cinco regiões do Brasil.
SOCIOECONOMIC MOBILITY, EXPECTATIONS AND ATTITUDES TOWARDS INEQUALITY IN BRAZIL
Authors: Salata André , Scalon Celi
Published: October 2020

Abstract After the end of the political and economic cycle that gave rise to the phenomenon that became known as the Brazilian new middle class, in this article we argue that this reading was not limited to verifying the increase in income and consume power of thousands of families, but also framed it within a broader narrative that has hindered the sociological investigation of the phenomenon. Thus, our first objective is to develop, with the support of empirical data from the National Household Sample Survey (PNAD-IBGE), an alternative interpretation of the changes observed in Brazilian society in recent years. Our second objective is to reflect, with the help of data from the Survey on the Middle Class (CESOP-UNICAMP-2008), and also from qualitative research previously prepared by the authors, on the possible impacts of these changes on the expectations of individuals and, thus, on their perceptions and attitudes towards the enormous inequalities still present in the country.
THEODOR ADORNO E ERIC HOBSBAWM SOBRE O JAZZ
Authors: Fridman Luis Carlos
Published: October 2020

Resumo O artigo traça um paralelo entre as concepções de Theodor Adorno e Eric Hobsbawm sobre o jazz e intenta uma crítica dos argumentos envolvidos nas concepções estéticas dos autores sobre o gênero musical. Na obra de Adorno, busca discutir o alcance do conceito de indústria cultural e suas considerações em torno do fetichismo e da regressão da audição, resultando em apreciações que ressaltam o caráter ideológico e os traços conformistas do jazz. O contraponto encontrado nos escritos de Hobsbawm destaca no jazz a ampliação das fronteiras no campo da música popular, imbricada às suas origens populares, e a elevação estética dos ouvintes.

LÍMITES Y POTENCIALIDADES DE LA FORMACIÓN UNIVERSITARIA EN AMÉRICA LATINA PARA LA PRÁCTICA DE LA EXTENSIÓN RURAL
Authors: Landini Fernando
Published: October 2020

RESUMEN Los estudios sobre formación de extensionistas suelen focalizar en la implementación de capacitaciones, quedando en segundo plano la educación universitaria. Se analizaron los límites y potencialidades de la universidad para formar extensionistas a partir de entrevistas a 133 técnicos de diferentes países latinoamericanos. Los resultados muestran que la formación de grado en ciencias agropecuarias incluye contenidos insuficientes sobre extensión, la educación suele ser excesivamente teórica, y predomina un enfoque que simplifica en exceso la complejidad de los agroecosistemas. A la vez, se observa que los posgrados y diplomados en extensión y desarrollo rural poseen gran potencialidad.

Authors: Santos Aline Veiga dos , Chaves Vera Lúcia Jacob
Published: October 2020

RESUMO A privatização da educação superior brasileira se fundamenta no discurso ideológico da impossibilidade de financiamento do setor estatal. Como solução, aponta-se o estabelecimento de parcerias público-privadas. O objetivo deste artigo é apresentar análise sobre a articulação de atores privados no direcionamento das políticas que visam ao fortalecimento da privatização do setor. O texto resulta de pesquisa documental, orientada por uma perspectiva crítica. Conclui-se que o processo de privatização da educação superior é multifacetado e interage com uma rede de governança fortemente relacionada com os empresários da educação e as conectividades com os organismos transnacionais.

RESUMO O artigo analisa a parceria público-privada entre a Secretaria da Educação do Estado de São Paulo (SEE-SP) e a Associação Parceiros da Educação (APE) em torno do Programa Educação - Compromisso de São Paulo, no período 2015-2018. A parceria serviu como modelo de estudo das relações público-privadas na educação, à luz dos conceitos de neoliberalização e heterarquização. Utilizando um algoritmo capaz de inferir redes políticas a partir de documentos físicos digitalizados, identificamos três dinâmicas de complexificação da privatização da educação em São Paulo: 1) a incorporação da APE na estrutura de governança da educação pública; 2) a porosidade entre políticas educacionais e a mobilidade da APE para além do escopo inicial da parceria; e 3) a atuação da APE na ampliação da rede de governança, atuando como boundary spanner e facilitando a entrada de outras organizações privadas.

ABSTRACT Two assays were performed to estimate digestible threonine-lysine (Threo-Lys) ratio for female meat-type quails between 21 and 28 days old and between 28 and 35 days old. Experimental design was totally randomized. The first assay comprised 440 quails distributed into 5 treatments, 8 replications and 11 fowls per cage. The second assay comprised 280 quails distributed into 5 treatments, 8 replications and 7 fowls per cage. Five digestible Threo: Lys ratios were evaluated (0.66, 0.71, 0.76, 0.81 and 0.86). Performance, carcass and cut yield, chemical composition of carcass and nitrogen balance were evaluated. There was an improvement (P<0.05) in feed conversion and increase in feed intake due to ratios of digestible Threo: Lys between 21 and 28 and between 29 and 35 days olds, respectively. At 35 days old, there was a better (P<0.05) carcass yield and a negative nitrogen balance for Threo: Lys analyzed. A ratio of 0.86 may be recommended for digestible Threo: Lys as the best for feed conversion and carcass yield for female meat-type quails between 21 and 28 and between 28 and 35 days.
Um ajuste justo ou mais alguns passos atrás para a educação básica pública no Brasil?
Authors: Ferreira Eduardo Carvalho
Published: October 2020

Resumo Neste artigo, iremos apresentar e discutir o relatório Um ajuste justo: análise da eficiência e equidade do gasto público no Brasil (2017), produzido pelo Banco Mundial para conjecturar acerca da necessidade de um ajuste fiscal radical para sanar as finanças e os problemas orçamentários do país. O relatório em questão apresenta alguns argumentos e estratégias para a execução de um ajuste das contas públicas, em especial, para setores como saúde, educação, previdência social, dentre outros. Partindo de uma abordagem crítica acerca das recomendações do Banco para a educação básica pública brasileira, questionamos as diretrizes expressas no documento, que apontam para a necessidade de contingenciamentos e cortes no orçamento como forma de melhorar as contas e equilibrar a razão investimento/resultados. O relatório ampara-se em uma econometria que busca legitimar a todo custo a tese que vê na política fiscal contracionista o melhor caminho para intervir na educação básica pública. Ao longo do texto, discutimos se isso é factível considerando o nosso contexto histórico de subfinanciamento, onde, diferentemente de outros países mais ricos e menos desiguais, jamais alcançamos um patamar de investimentos suficientes para garantir o acesso, a permanência e a qualidade na educação básica.
A sustainable multi-criteria decision making framework to select interior walls

Published: October 2020

With an increasing number of different materials, choosing the best one has become an arduous task. The vast domain of alternatives and decision criteria has led to the complexity of decision making in the conceptual phase for designers. On the other hand, due to the importance of environmental and energy concerns, considering the sustainability principles through the decision process is significantly important. Although sustainable material selection as a strategy leads to some general and main assessment criteria, identification of sub-criteria not only depends on general criteria but also pertains to the specific type of elements in buildings. Interior walls are one of those elements in construction with a complex decision making process due to their great variety of types and features. This paper aims to provide a sustainable multi-criteria decision making framework for choosing the proper interior walls in buildings. A qualitative research method using literature review, unstructured interviews and questionnaires was adopted to achieve the aims of this research. The initial data, including the criteria and sub-criteria, were collected through literature review. A framework consisting of four main components related to environmental, financial, social and technical aspects was finally developed and validated through unstructured interviews held with 23 experts in the construction industry in Iran. By dividing the main criteria into sub-criteria, in total, 23 sub-criteria were identified; to calculate their weight, questionnaires were distributed among 143 experts in the construction industry in Tehran and the analytic hierarchy process method was applied. High-rise residential buildings in Tehran were selected as a case to apply the framework, and finally the results are discussed.
Simplified approach to assess the vulnerability of masonry buildings under tsunami loads
Authors: Belliazzi Stefano , Lignola Gian Piero , Prota Andrea
Published: October 2020

Several catastrophic tsunami events in recent years have engaged scientific awareness to assess the tsunami risk. Fragility curves are required to analyse the vulnerability of masonry buildings and analytical fragility curves should be based on local building typologies. The aim of this study was to assess the vulnerability of masonry buildings under tsunami loads by means of the minimum inundation depth to trigger a failure mechanism. This was done using a large-scale approach and with a low knowledge level of the properties of structures. The activation of out-of-plane and in-plane mechanisms was investigated by modelling an external tsunami load pattern using simplified assumptions. Shear and flexural failure were analysed as the main in-plane failure modes while horizontal and vertical bending mechanisms were considered as the main out-of-plane failure modes. Masonry walls were modelled as frame elements and the masonry was modelled as a non-linear material. Japanese guidelines were assumed for modelling tsunami loads instead of more refined models such as those in ASCE 7-16 and Fema P-646, due to the reduced achievable knowledge level. The proposed mechanical models provide important information about the vulnerability of masonry buildings under tsunami loads and represent a basic step to provide vulnerability information on masonry buildings on a regional scale.
Impact of different stocking densities of sheep on establishing stands of Larix sibirica in Iceland

Published: October 2020

The present study was the first in Iceland to investigate the effects of different stocking densities of sheep on planted Siberian larch (Larix sibirica) trees. It covered two years and involved four stocking densities in enclosures with 0.1–3.0 m tall trees, as well as a grazed area on treeless commons. The grazing effect was followed for 75 days each summer. A significant grazing effect was found on the vegetation in both years. None of the sheep stocking densities had a measurable effect on the growth or the survival of the larch trees, however, and no damage was observed on their apical shoots. During the second summer, significant visual and measured browsing effects were recorded on side branches in enclosures with medium and high stocking densities. No trees <0.5 m were browsed, however. Siberian larch is generally not sought after by sheep and the results indicated that it may be generally safe to utilize established monoculture Siberian larch stands for sheep grazing during the summer months, if enough other vegetation is present.

Background: Cimifugin is one of the components of the root of Saposhnikovia divaricata. The extract derived from S. divaricata is traditionally used as an analgesic. This study was conducted to evaluate the analgesic effect of intrathecal cimifugin in the formalin test.Methods: Male Sprague–Dawley rats (n = 20) were randomized into four groups for intrathecal administration of 70% dimethylsulfoxide and various doses of cimifugin (100 μg, 300 μg, and 1,000 μg). The typical flinch response after the injection of 5% formalin into the hind paw was assessed in two distinct phases: phase 1 until 10 min, and phase 2 from 10 min to 60 min. ED50 values were calculated via linear regression.Results: Intrathecal cimifugin significantly reduced the flinch response in both phases of the formalin test. Significant antinociceptive effects of cimifugin were found with the dose of 300 μg in phase 1 and the dose of 100 μg in phase 2. The ED50 value (95% confidence intervals) of intrathecal cimifugin was 696.1 (360.8–1,342.8) μg during phase 1 and 1,242.8 (42.0–48,292.5) μg during phase 2.Conclusions: Intrathecal cimifugin has an antinociceptive effect against formalin-induced pain. Cimifugin has an anti-inflammatory effect at low concentrations, and non-inflammatory analgesic effect at higher concentrations.

Published: October 2020

Background: Fontan-associated liver disease (FALD) is a hepatic disorder caused by hemodynamic changes and systemic venous congestion following the Fontan procedure. FALD includes liver cirrhosis and hepatocellular carcinoma (HCC), both of which may require liver transplantation (LT). However, the Fontan circulation, characterized by elevated central venous pressure and reduced cardiac output, is a challenging issue for surgeons and anesthesiologists.Case: We report a living-donor LT for the treatment of HCC. The patient was a 24-year-old male who underwent the Fontan procedure for pulmonary atresia and right ventricle hypoplasia. We focused on maintaining enough blood volume for cardiac output without causing pulmonary edema, as the patient is not well adapted to changes in volume. Owing to a multidisciplinary approach, the surgery was successfully performed without fatal adverse events.Conclusions: To our knowledge, this is the first case of isolated LT in a recipient who became an adult after having undergone the Fontan procedure.
