O objetivo aqui é apresentar uma resenha do volume 14 dos Collected Papers of Albert Einstein (CP 14), que contém os escritos científicos e cartas de Einstein do período de 1923 a 1925 e que comemoram agora seu centenário, limitando-nos à parte que se refere à história da física no Brasil: sua viagem ao país, ocorrida em 1925.

Se describen a los micro-papers como formatos novedosos e incipientes para la difusión del conocimiento científico, tanto en revistas científicas como a través de otros métodos nativos del Internet (repositorios, blogs, etcétera). Planteamos la importancia de la utilización de este formato reducido de comunicación de la ciencia para transmitir ciertos tipos de hallazgos, pues presenta una condensación de la información básica en un documento breve, de fácil lectura y con amplia audiencia, sin perder la calidad propia de los trabajos científicos revisados. Para ello, se realiza un estudio descriptivo de carácter exploratorio por medio de una revisión bibliográfica que ahonda en su uso actual y experiencias previas. Concluimos que su viabilidad para la difusión de contenidos científicos concretos busca la agilidad, sin que ello implique la pérdida de la calidad en la difusión científica.

This paper presents the initial findings of a qualitative study investigating the relationship between ethics and education in Italian preschool settings. The research employs the methodology of Constructivist Grounded Theory (CGT) to emphasise the indispensable role of promoting ethical awareness in early childhood education. The preliminary results from the interpretation of intensive interviews with preschool teachers indicate that the structuring of ethically significant educational experiences can be a factor in the growth of ethical awareness. From a theoretical and practical perspective, the study posits that stimulating ethical awareness from early childhood can prevent the rise of an increasingly widespread phenomenon: ethical illiteracy.

APPLICATION OF MASS SPECTROMETRY WITH PAPER SPRAY IONIZATION AND THE OPLS-DA CHEMOMETRIC METHOD FOR THE DIAGNOSIS OF PROSTATE CANCER BY ANALYSIS OF URINE SAMPLES. In this study, paper spray ionization mass spectrometry (PSI-MS) allied to orthogonal projections on the latent structure-discrimination analysis (OPLS-DA) was employed to differentiate urine samples from patients with prostate cancer and control individuals (without prostate cancer). The parameters of sensitivity, specificity, efficiency and Matthew’s correlation coefficient determined to analyze the efficiency and quality of the OPLS-DA model obtained a value equal to 1, which means, respectively, that the model has a good performance to correctly classify true positive samples and true negatives. These results showed 100% correct classification of the samples from the training and test set, demonstrating a high efficiency of the OPLS-DA model when classifying all samples considered as belonging to the class of interest (urine from control patient) into class 1 and all samples considered as belonging to the non-interest class (urine from patients with prostate cancer) in class 0. This efficiency resulting from the application of this model suggests that the PSI-MS combined to OPLS-DA is a promisor approach for a rapid diagnosis of prostate cancer, via chemical fingerprints of urine samples.

Este volume surge como consequência direta do Simpósio internacional PAPER TRAILS: post-industrial histories, technical memories and art practices in Tomar que teve lugar em Tomar (Portugal) entre 25 e 27 de maio de 2022. Por sua vez, o simpósio insere-se num projeto homónimo concebido, em parceria com colaboradoras da École de Design et Haute École d’Art du Valais (EDHEA), no Centro de Tecnologia, Restauro e Valorização das Artes (TECHN&ART), uma unidade de Investigação e Desenvolvimento financiada pela Fundação para a Ciência e a Tecnologia (FCT) com a referência UID/05488/2020 e pertencente ao Instituto Politécnico de Tomar (IPT).

Se trata de exploraciones esenciales en torno al papel, su textura y las relaciones originadas a partir de su recorte y superposición en capas. Son obras minimalistas en su técnica que despliegan paisajes de formas plegadas y laminadas con profundidad y equilibrio que parten también del imaginario personal sobre la arquitectura. Las composiciones tienen un formato de 21x21 cm. Las mismas reglas operan en todas ellas: el orden y el número de capas, colores, etc., pero se recombinan en cada pieza de forma diferente. Las capas de papel se separan entre sí a unas distancias concretas y se unen de forma solidaria sólo por una pestaña en la parte superior, lo que permite una cierta libertad y tolerancia en la separación entre ellas, de forma que la percepción puede variar levemente en función del plegado o la curvatura del papel, incluso de las condiciones de humedad y atmosféricas.

This study analyzes the process of productive specialization of the work in Maranhão, through the advance triggered by the implementation of the manufacturing unit of Suzano Paper and Cellulose in the municipality of Empress, southwest of the state. Methodologically, in addition to reviewing the relevant literature, secondary data on transformations in local employment and local professional qualifications derived from the implementation of Suzano were used together with field research. The data used originate from RAIS; CAGED; IBGE, in addition to technical schools and local universities. The results found made it possible to verify that there is a specialization of the workforce in progress to meet the logic and full functioning of the pulp production chain in Imperatriz - MA.

Global warming is a result of the increased emission of greenhouse gases. The consequences of this climate change threaten society, biodiversity, food and resource availability. The consequences include an increased risk of cardiovascular (CV) disease and cardiovascular mortality.In this position paper, we summarize the data from the main studies that assess the risks of a temperature increase or heat waves in CV events (CV mortality, myocardial infarction, heart failure, stroke, and CV hospitalizations), as well as the data concerning air pollution as an enhancer of temperature-related CV risks. The data currently support global warming/heat waves (extreme temperatures) as cardiovascular threats. Achieving neutrality in emissions to prevent global warming is essential and it is likely to have an effect in the global health, including the cardiovascular health. Simultaneously, urgent steps are required to adapt the society and individuals to this new climatic context that is potentially harmful for cardiovascular health. Multidisciplinary teams should plan and intervene healthcare related to temperature changes and heat waves and advocate for a change in environmental health policy. Resumo: O aquecimento global é uma das consequências do aumento da emissão de gases com efeito de estufa. Essa consequência das alterações climáticas é uma ameaça à sociedade, à biodiversidade e à disponibilidade de recursos e alimentos. As consequências para a saúde do aquecimento global incluem o aumento do risco de doenças cardiovasculares (CV) e da mortalidade cardiovascular.Neste position paper resumimos os dados dos principais estudos que avaliam o risco do aumento de temperatura ou a exposição a ondas de calor nos eventos CV (mortalidade CV, enfarte do miocárdio, insuficiência cardíaca, acidente vascular cerebral e hospitalizações CV), assim como os dados relativos à poluição do ar como um potenciador dos riscos de eventos CV relacionados com o aumento da temperatura. Os dados atualmente disponíveis confirmam que o aquecimento global e as ondas de calor (temperaturas extremas) são ameaças cardiovasculares. Nesse contexto, a neutralidade nas emissões deve ser um objectivo prioritário, de modo a reduzir o aquecimento global e, desse modo, reduzir o seu impacto na saúde global, inclusive a saúde cardiovascular. Simultaneamente, deverão ser empregues medidas urgentes de adaptação setorial ao novo contexto climático, potencialmente mais nefasto para a saúde cardiovascular. Equipes multidisciplinares devem planear e intervir nos cuidados de saúde relacionados com o calor e discutir as políticas de saúde relacionadas com o ambiente.

The field of Cardio-Oncology has grown significantly, especially during the last decade. While awareness of cardiotoxicity due to cancer disease and/or therapies has greatly increased, much of the attention has focused on myocardial systolic disfunction and heart failure. However, coronary and structural heart disease are also a common issue in cancer patients and encompass the full spectrum of cardiotoxicity. While invasive percutaneous or surgical intervention, either is often needed or considered in cancer patients, limited evidence or guidelines are available for dealing with coronary or structural heart disease. The Society for Cardiovascular Angiography and Interventions consensus document published in 2016 is the most comprehensive document regarding this particular issue, but relevant evidence has emerged since, which render some of its considerations outdated. In addition to that, the recent 2022 ESC Guidelines on Cardio-Oncology only briefly discuss this topic.As a result, the Portuguese Association of Cardiovascular Intervention and the Cardio-Oncology Study Group of the Portuguese Society of Cardiology have partnered to produce a position paper to address the issue of cardiac intervention in cancer patients, focusing on percutaneous techniques. A brief review of available evidence is provided, followed by practical considerations. These are based both on the literature as well as accumulated experience with these types of patients, as the authors are either interventional cardiologists, cardiologists with experience in the field of Cardio-Oncology, or both. Resumo: A Cardio-Oncologia cresceu consideravelmente, particularmente ao longo da última década. Não obstante o aumento de sensibilização relativamente à cardiotoxicidade secundária ao cancro e/ou a terapêuticas oncológicas, muita da atenção tem-se focado na disfunção sistólica e insuficiência cardíaca. Todavia, a doença coronária e estrutural cardíaca representam também um desafio comum em doentes oncológicos, fazendo assim parte do abrangente conceito de Cardio-Oncologia. Apesar da necessidade de intervenção invasiva, percutânea ou cirúrgica ser frequentemente necessária ou considerada em doentes com cancro, é escassa a evidência ou recomendações relativas à doença coronária ou estrutural neste subgrupo. O documento de consenso da Society for Cardiovascular Angiography and Interventions, publicado em 2016, é a referência mais completa relativamente a esta problemática. Contudo, alguma evidência que entretanto surgiu torna necessária uma atualização. Adicionalmente, as recentes recomendações de 2022 em Cardio-Oncologia da Sociedade Europeia de Cardiologia abordam este assunto somente de forma muito sucinta.Por este motivo, a Associação Portuguesa de Intervenção Cardiovascular e o Grupo de Estudos de Cardio-Oncologia associaram-se para produzir um Artigo de Posição sobre Intervenção Cardíaca em doentes com cancro, com foco nas técnicas percutâneas. Procedeu-se a uma breve revisão da literatura, seguida de considerações práticas. Estas baseiam-se na evidência disponível, bem como na experiência acumulada dos autores, que são Cardiologistas de Intervenção, Cardiologistas dedicados à área da Cardio-Oncologia, ou ambos.

During the recycling of a cardboard box in the shape of a right prism with a square base to build a tetrahedron, there was the curious coincidence that the height of the first was equal to the inclined height of the second. After some bending and cutting on the prism, its dynamic conversion to the tetrahedron and vice versa was achieved. This fact motivated us to carry out a study on the meaningful learning of a small group of participants (N = 10) with minimum primary school education, regarding the volume of these two common geometric bodies. It was found that 70 % of the study population thought that the volumes were equal and that 100 % had forgotten the formula to calculate the volume of the tetrahedron. A template to build the model and a video to illustrate the mentioned transformation process are also presented.

In recent years, technological development in analytical instrumentation has progressed vigorously, which has allowed the evolution of analytical techniques that play an indispensable role within society, highlighting mass spectrometry. Parallel to the technological advance of this technique, the development of new ionization methods that are simpler, faster, and allow direct analysis without the need for prior treatment or sample processing is underway. The methods of ambient ionization derived from paper spray have been developing rapidly in current days, mainly in the forensic field, due to the chemical modifications made in the paper substrate and the introduction of new types of organic materials that function as a probe/substrate to collect, store, and ionize the sample, then enabling more efficient and selective analyzes. This review highlights direct analyzes by applying paper spray ionization in the forensic field and some variations of this technique, including Thread Spray Ionization (TSI) when a fabric thread is used; Touch Spray Ionization (TSI), which uses materials such as metallic needles, medical swabs, and wooden sticks; Fiber Spray Ionization (FSI), which applies polymeric fibers as substrates.

As in other countries, In Brazil, new genetic materials of Eucalyptus spp. and their hybrids are multiplied through cloning. These materials, currently in experimental trials, must undergo several stages to select the best ones for pulp and paper production. Therefore, new studies on wood quality are essential. Therefore, this study aimed to group 11 clones of Eucalyptus spp. wood, from a clonal plantation in the municipality of Palmital, São Paulo State, for the production of paper and cellulose. For this purpose, four trees of each clone of 4-year-old Eucalyptus spp. were collected. From each tree, a log of 1 m in length was taken from the base of the tree, for the study of the characterization of the basic density and cellular dimensions of the wood. The results showed that there were significant differences between clones for basic density, fiber length, vessel element length and fiber wall thickness. The Runkel ratio, wall fraction and stiffness coefficient did not show significant differences between the different genotypes. From the results obtained, we can conclude that clones can be differentiated only by basic density, fiber length, vessel element length and fiber wall thickness. The Runkel index, flexibility coefficient and wall fraction of Eucalyptus spp. were more efficient to group the clones into two groups.

Abstract Objective The purpose of the present study is to standardize and evaluate the use of the immunoglobulin G (IgG) antibody avidity test on blood samples from newborns collected on filter paper to perform the heel test aiming at its implementation in ongoing programs. Methods Blood samples from newborns were collected on filter paper simultaneously with the heel prick test. All samples were subjected to immunoglobulin M IgM and IgG enzyme-linked immunosorbent assays (ELISA). Peripheral blood was collected again in the traditional way and on filter paper from newborns with high IgG levels (33). Three types of techniques were performed, the standard for measuring IgG in serum, adapted for filter paper and the technique of IgG avidity in serum and on filter paper. The results of the avidity test were classified according to the Rahbari protocol. Results Among the 177 samples, 17 were collected in duplicate from the same child, 1 of peripheral blood and 1 on filter paper. In this analysis, 1 (5.88%) of the 17 samples collected in duplicate also exhibited low IgG avidity, suggesting congenital infection. In addition, the results obtained from serum and filter paper were in agreement, that is, 16 (94.12%) samples presented high avidity, with 100% agreement between the results obtained from serum and from filter paper. Conclusion The results of the present study indicate that the avidity test may be another valuable method for the diagnosis of congenital toxoplasmosis in newborns.

ABSTRACT BACKGROUND: The concept introduced by protocols of enhanced recovery after surgery modifies perioperative traditional care in digestive surgery. The integration of these modern recommendations components during the perioperative period is of great importance to ensure fewer postoperative complications, reduced length of hospital stay, and decreased surgical costs. AIMS: To emphasize the most important points of a multimodal perioperative care protocol. METHODS: Careful analysis of each recommendation of both ERAS and ACERTO protocols, justifying their inclusion in the multimodal care recommended for digestive surgery patients. RESULTS: Enhanced recovery programs (ERPs) such as ERAS and ACERTO protocols are a cornerstone in modern perioperative care. Nutritional therapy is fundamental in digestive surgery, and thus, both preoperative and postoperative nutrition care are key to ensuring fewer postoperative complications and reducing the length of hospital stay. The concept of prehabilitation is another key element in ERPs. The handling of crystalloid fluids in a perfect balance is vital. Fluid overload can delay the recovery of patients and increase postoperative complications. Abbreviation of preoperative fasting for two hours before anesthesia is now accepted by various guidelines of both surgical and anesthesiology societies. Combined with early postoperative refeeding, these prescriptions are not only safe but can also enhance the recovery of patients undergoing digestive procedures. CONCLUSIONS: This position paper from the Brazilian College of Digestive Surgery strongly emphasizes that the implementation of ERPs in digestive surgery represents a paradigm shift in perioperative care, transcending traditional practices and embracing an intelligent approach to patient well-being.

Occupational toxicology in the paper industry aims to study the occupational risks of exposure to chemical, physical and biological compounds used in the workplace, in addition to helping and preventing the possible appearance of adverse effects on the health of workers due to exposure to themselves. The pulp and paper industries use several chemical agents in the production of packaging, demanding attention to handling due to their toxic action, currently research in this area is scarce. In turn, this article sought to demonstrate, through questionnaires and chemical analysis, contamination by hydrochloric acid and sodium hydroxide in workers during their work activity in a paper industry located in southern Brazil. Seeking to increase the studies, the workers' knowledge about the agents was investigated, as well as the use of Personal Protective Equipment (PPE) and the contamination of these individuals with the aforementioned agents. To achieve these objectives, interviews were applied to employees from four different shifts and the clothes were analyzed after the end of the shift through titration and pHmetry analysis. The results of the analyzes showed a lack of awareness among the workers, evidence of contamination and traces of sodium hydroxide on the employees' clothing. These results imply reflection on the indispensability of personal protective equipment. Highlighting the need for the routine use of PPE, as well as offering the necessary qualification for workers, in order to prevent and minimize occupational accidents. [ABSTRACT FROM AUTHOR]

In this paper, we estimated the methane emissions by the disposal of sanitary and domestic-use paper consumed throughout Brazil from 1901 to 2016. The apparent consumption of this type of paper from 1961 to 2016, calculated from the data of the FAOSTAT system, was used to estimate the amount of waste disposed of annually in three site categories: sanitary landfill, controlled dump, and open-air, uncontrolled dump. The 2006 IPCC Guide methodology was used to calculate CH4emissions and long-term carbon storage. Nine scenarios based upon the law that establishes the National Solid Waste Policy (NSWP) were examined, considering 100% waste disposal and treatment in landfills or incineration from 2014. The total emission was estimated at 1.967 MtCH4, corresponding to 55.080 MtCO2eq by GWP-AR5, and the stored carbon at 3.724 Mt, corresponding to 13.655 MtCO2eq. CH4emission increased beyond the population growth rate due to an increase in the per capita paper consumption in the country, from 0.02 kgCH4.year-1 in 1961 to 0.30 kg CH4.year-1 in 2016. The NSWP has not yet been accomplished, and the scenarios outlined indicate that, from the point of view of CH4 emissions, it would be more advantageous to carry out incineration instead of applying other waste treatment technologies.

Este artigo tem por objetivo identificar os fatores que têm afetado as receitas das exportações de celulose e papel e papelão, no período de 2001 a 2020. Especificamente pretende-se quantificar as variações nas receitas provenientes da taxa de câmbio, do preço internacional e da quantidade exportada de celulose e de papel e papelão e identificar os principais eventos associados essas variações. Para tanto, utilizou-se o método diferencial-estrutural, conhecido como shift-share, que decompõe as variações da receita de exportação em efeitos parciais proporcionado por outras variáveis relacionadas. Os resultados mostram que mesmo quando os efeitos do preço internacional e a taxa de câmbio são desfavoráveis a quantidade exportada de celulose e de papel e papelão tem sido crescente, e proporcionando efeito total positivo nas receitas das exportações. Somente em quatro grandes momentos houve queda nas receitas das exportações destes produtos, momentos estes que coincidem com a ocorrência das seguintes crises: atentado a torres gêmeas (2002), crise do subprime (2008), crise política interna (2016) e pandemia (Covid-2019). ABSTRACT: This paper aims to identify the factors that have affected revenues from pulp and paper and paperboard exports, in the period from 2001 to 2020. Specifically, it intends to quantify the variations in revenues arising from the exchange rate, the international price and the exported quantity of Wood pulp and paperbord and identify the main events associate these variations. For this purpose, the differential-structural method, known as shift-share, was used, which breaks down changes in export revenue into partial effects provided by other related variables. The results show that even when the effects of the international price and the exchange rate are unfavorable, the exported quantity of woodpulp and paperboard has been increasing, providing a positive overall effect on export revenues. Only in four major moments were there decreases in revenues from exports of these products, moments that coincide with the occurrence of the following crises: attack on the twin towers (2002), subprime crisis (2008), internal political crisis (2016) and pandemic (Covid- 2019).

Abstract: Authors from different countries have published their papers in English, aiming to promote their research results widely and to become internationally known by their peers. It is also true that, although they are aware of the English terminology used in their respective field, some authors still struggle with some features of academic writing such as collocations. Thus, this paper presents a discussion on the underuse and overuse traces of academic collocations by Brazilian authors who had their articles published in English on an open electronic library of scientific journals. In order to analyse the collocations used by these researchers, we compiled a 906,035-word corpus from eight different academic areas. The collocations observed were statistically compared to those from an academic corpus of English writings which contains texts produced by English-speaking authors. Results showed that there are more collocations underused than overused by the authors. The analysis proved that the collocation repertoire of researchers could be broadened by being pointed out during academic writing workshops. Keywords: academic collocations; research paper writing; corpus linguistics. Resumo: Autores de vários países têm publicado seus artigos científicos em inglês com o intuito de promover amplamente os resultados de suas pesquisas dentre a comunidade científica internacional. É verdade que, embora estejam cientes da terminologia utilizada no respectivo campo de pesquisa, alguns autores ainda apresentam dificuldade em lidar com certas características da escrita acadêmica, como o uso das colocações. Este artigo apresenta uma discussão sobre traços de sobreuso e subuso de colocações acadêmicas utilizadas por autores brasileiros que têm seus artigos publicados em inglês numa plataforma eletrônica aberta de artigos científicos. Para analisar as colocações utilizadas por estes pesquisadores, compilamos um corpus de 906.000 palavras a partir de oito áreas científicas. As colocações analisadas foram comparadas estatisticamente com as colocações de um corpus acadêmico de inglês que contém textos escritos por autores anglófonos. Os resultados mostraram que há mais traços de subuso que sobreuso de colocações acadêmicas utilizadas pelos pesquisadores e este repertório poderia ser ampliado se fossem destacadas durante cursos de escrita acadêmica em língua inglesa. Palavras-chave: colocações acadêmicas; escrita de artigos científicos; linguística de corpus.

Esse texto discute a formação do espaço econômico paranaense e sua relação com as atividades de base econômica ou exportação. A análise segue uma visão institucionalista a partir da teorização de Douglass North. A análise também se embasa em Pedro Calil Padis, por fazer um retrospecto eficaz dos primórdios do Paraná até o final dos anos 1960. Se parte do princípio de que várias economias regionais que surgiram no Brasil estavam em condições periféricas. O termo “periférico” é devido ao fato de a economia de cada uma dessas regiões ou Estados estar subordinada ao centro dinâmico do país devido a vários fatores, dentre eles a transferência de capital, fazendo com que o Paraná, com sua economia cafeeira, subsidiasse a indústria paulista. Abstract: This paper discusses the formation of the economic space of Paraná State and its relationship with economic-based activities or exports. The analysis follows an institutionalist vision based on Douglass North's theorization. The analysis is also based on Pedro Calil Padis, for making an effective retrospective of the beginnings of Paraná State until the end of the 1960s. It is based on the principle that several regional economies that emerged in Brazil were in peripheral conditions. The term “peripheral” is since the economy of each of these regions or states is subordinated to the dynamic center of the country due to several factors, including the transfer of capital, causing Paraná, with its coffee economy, to subsidize the São Paulo industry.

In the criminal sphere, it is extremely important to identify perpetrators of crimes based on latent fingerprints (invisible to the naked eye) revealed at crime scenes and their corresponding objects. The present work aimed to evaluate four synthetic analogues of curcumin as possible IDL developers, and to compare their results with those of carbon black developer, as well as to reach the most adequate parameters in the use of the LTQ and FT-ICR mass spectrometers with the paper spray ionization (PS) source to study the chemical composition of the endogenous substances contained in the IDL. For this, a 24-1 factorial design was developed, where it was verified that the distance and voltage factors were the most influential for the increase in the response of signals, in the analysis of latent fingerprints by PS. Among the detected substances we can mention around 20 fatty acids, and squalene. Finally, four potential developers, synthetic analogues of curcumin, were compared with carbon black developer. The revelation of latent fingerprints occurred efficiently, allowing the visualization of minutiae, such as bifurcation and end of line, making it possible to classify them, according to the Vucetich Fingerprint Classification System.

As práticas pedagógicas centradas em videojogos têm vindo a tornar-se cada vez mais populares, dado oferecerem vantagens empiricamente validadas no que diz respeito ao envolvimento dos alunos, à sua motivação e sentido de agência. Estes construtos afetivos são agora reconhecidos como componentes-chave de uma aprendizagem eficaz e significativa, favorecendo o desenvolvimento de competências cognitivas de nível superior. Contudo, enquanto se atesta um número elevado de estudos sobre o uso de videojogos educativos nas áreas das Ciências, Tecnologia, Engenharia e Matemática (STEM), é necessário ainda explorar as potencialidades desses recursos nas disciplinas de Humanidades. Analogamente, devem ser empreendidos mais esforços no sentido da investigação e implementação de atividades que atribuam aos alunos, especialmente àqueles de níveis inferiores ao do Ensino Superior, o papel de designers de videojogos, aliado ao de jogadores. Desta feita, criam-se as condições para que os alunos construam material didático autêntico, sob a forma de experiências digitais imersivas, que apresentam tanto um valor educacional como de entretenimento. Assim, este artigo funciona como um Position Paper sobre a Aprendizagem Baseada em Jogos Digitais ou Digital Game-based learning (DGBL), descrevendo as vantagens afetivas de se jogar e criar videojogos educativos na sala de aula de Humanidades, enquanto reflete criticamente sobre possíveis obstáculos ao sucesso desta prática. O nosso objetivo é estudar como a tecnologia educativa e imersiva pode satisfazer as necessidades de aprendizagem da Geração Z, tendo em consideração os diferentes fatores contextuais que definem o seu perfil.

Having the South American Amazon as our spatial cut, this paper aims to discuss it as a space of physical, environmental and socioeconomic relevance to regional rearticulation, highlighting the issue of transport infrastructure and the importance of Brazil to boost this process in contemporary times. With the end of the Union of South American Nations (Unasur) in 2019, several of its councils were paralyzed and discontinued, such as the Infrastructure and Planning Council (Cosiplan), reflecting the abandonment of efforts built since the beginning of the 21st century. In addition, relations between national preferences and the indispensable search for development, and mechanisms of cooperation and regional integration, which are fundamental instruments to meet such demands, were stressed. In turn, a scenario of discredited institutions made room for greater action by multiple public and private, internal and increasingly international and multinational actors who, in a way disconnected from regional arrangements, directed infrastructure investments focusing on their own interests, resulting in expiation of the the socio-environmental vulnerability in the Amazonian territories. We argue that it is necessary to integrate to preserve and develop. Regional governance and institutionality are central pillars for the resumption of a more resilient South American integration process, aimed at protecting and developing the Amazon, in which Brazil has an important driving role to be exercised and a directive leadership to retrieve.

The article seeks to identify if cryptocurrency white papers bring purely technical positions. The research is justified on the growing discussion regarding the regulation of cryptocurrencies. Aside this discussion, there is a scenario in which cryptocurrencies seem to have emerged precisely from an attempt to move away from authoritative public control. At first, we analyzed the conceptualization of white papers, and their purposes. Subsequently, we evaluated the content of the cryptocurrency white papers with the highest market cap at the time of the esearch. We identified the presence of political-ideological content coupled with the technical content in these documents. Finally, the presented result shows that political-ideological elements in white papers can serve the regulating agent in their decision-making process, either to decide whether or not to regulate, but also to define the limits of their performance.

This paper aimed to determine the quality indexes for paper and cellulose based on the fiber features from two wood species of interest, Eucalyptus pellita and E. tereticornis. The mean annual increment (IMA) was calculated by measuring DBH and Height (25 years), a 10 cm disk from each tree was collected for density determinations and anatomical studies for cellulose and paper. Tree height, trunk diameter at 1.30 m in height (DBH), and volume per tree were higher in E. pellita when compared to E. tereticornis. The volume per hectare and average annual increment were higher in E. tereticornis compared to E. pellita. Based on the quality indexes calculated from fiber dimensions, we did not observe any variation in flexibility coefficient between the two species; however, this index was more heterogeneous with the lowest value in E. tereticornis pith. Eucalyptus pellita showed a lower wall fraction value, including a lower overall value in pith. The Runkel index was lowest in E. pellita; in addition, the highest value, above 1, was found in pith position in E. tereticornis. The slenderness index did not differ between species and it was not possible to detect which had performed better. The results indicate that E. pellita and E. tereticornis have potential for the production of paper with high mechanical resistance, such as writing, printing and packaging. The wood of both species has potential for use in producing paper and cellulose.

ABSTRACT Acute cholecystitis (AC) is an acute inflammatory process of the gallbladder that may be associated with potentially severe complications, such as empyema, gangrene, perforation of the gallbladder, and sepsis. The gold standard treatment for AC is laparoscopic cholecystectomy. However, for a small group of AC patients, the risk of laparoscopic cholecystectomy can be very high, mainly in the elderly with associated severe diseases. In these critically ill patients, percutaneous cholecystostomy or endoscopic ultrasound gallbladder drainage may be a temporary therapeutic option, a bridge to cholecystectomy. The objective of this Brazilian College of Digestive Surgery Position Paper is to present new advances in AC treatment in high-risk surgical patients to help surgeons, endoscopists, and physicians select the best treatment for their patients. The effectiveness, safety, advantages, disadvantages, and outcomes of each procedure are discussed. The main conclusions are: a) AC patients with elevated surgical risk must be preferably treated in tertiary hospitals where surgical, radiological, and endoscopic expertise and resources are available; b) The optimal treatment modality for high-surgical-risk patients should be individualized based on clinical conditions and available expertise; c) Laparoscopic cholecystectomy remains an excellent option of treatment, mainly in hospitals in which percutaneous or endoscopic gallbladder drainage is not available; d) Percutaneous cholecystostomy and endoscopic gallbladder drainage should be performed only in well-equipped hospitals with experienced interventional radiologist and/or endoscopist; e) Cholecystostomy catheter should be removed after resolution of AC. However, in patients who have no clinical condition to undergo cholecystectomy, the catheter may be maintained for a prolonged period or even definitively; f) If the cholecystostomy catheter is maintained for a long period of time several complications may occur, such as bleeding, bile leakage, obstruction, pain at the insertion site, accidental removal of the catheter, and recurrent AC; g) The ideal waiting time between cholecystostomy and cholecystectomy has not yet been established and ranges from immediately after clinical improvement to months. h) Long waiting periods between cholecystostomy and cholecystectomy may be associated with new episodes of acute cholecystitis, multiple hospital readmissions, and increased costs. Finally, when selecting the best treatment option other aspects should also be considered, such as costs, procedures available at the medical center, and the patient’s desire. The patient and his family should be fully informed about all treatment options, so they can help making the final decision.

Objetive. To know some characteristics of the communication channels used by the Brazilian Archival community. Method. It’s a bibliometric study about the prestige of scientific journals in articles of Brazilians archival science journals in order. The study use analysis of citations, with a random sample of complete 116 references of journal articles, and select reference data from the ABCDM database, from the Universidade de Brasília, which were exported into MS-Excel and SPSS. Results. The results present rankings of document types, journal titles and their countries, as well as the most frequent languages of these references. 78 channel types were identified, specially books (32.42%) and journal articles (22.46%). Among the 180 identified journal titles (89 Brazilian and 91 from other countries), the Brazilian most cited were Estudos Históricos (7.66%), Ciência da Informação (7.48%), Arquivo & Administração (5.47%), DataGramaZero (3.65%), Acervo (3.47%) and Arquivística.net (3.47%). Among foreigners, the most cited journals were Archivaria (6.02%), Archival Science (4.20%), American Archivist (3.47%) and Journal of the American Society for Information Science and Technology (2.19%). The countries with the most cited journals were Brazil (61.86%), United States (12.04%) and Canada (11.31%). The most mentioned language in the references were Portuguese (63.32%) and English (30.11%). Conclusions. The search to results point to a significant lack of specific current Brazilian journals and show that results resemble those of other research areas related to information areas in general, showing that Archival Science keep scientific communication features common to other areas of information in Brazil.

Este artigo visa apresentar como os veículos de mídia brasileiros apareceram na cobertura dos principais jornais e agências de notícias internacionais que trabalharam no país durante os anos do Regime Militar (1964-1985). Com este trabalho historiográfico, a pesquisa apresentada permite que se ampliem estudos sobre: as distinções entre os métodos de censura aplicados a veículos nacionais e internacionais; o decorrer das mudanças nas políticas externas brasileiras e estadunidenses ao longo dos 21 anos de ditadura, refletidas no jornalismo transnacional; a evolução midiática nacional e sua influência política, considerando as alterações no modelo jornalístico, outorgadas pela realidade da Guerra Fria. Este artigo ambiciona uma proposta interdisciplinar e transnacional para o objeto oferecido.

ABSTRACT BACKGROUND: Surgical antibiotic prophylaxis is an essential component of perioperative care. The use of prophylactic regimens of antibiotics is a well-established practice that is encouraged to be implemented in preoperative/perioperative protocols in order to prevent surgical site infections. AIMS: The aim of this study was to emphasize the crucial aspects of antibiotic prophylaxis in abdominal surgery. RESULTS: Antibiotic prophylaxis is defined as the administration of antibiotics before contamination occurs, given with the intention of preventing infection by achieving tissue levels of antibiotics above the minimum inhibitory concentration at the time of surgical incision. It is indicated for clean operations with prosthetic materials or in cases where severe consequences may arise in the event of an infection. It is also suitable for all clean-contaminated and contaminated operations. The spectrum of action is determined by the pathogens present at the surgical site. Ideally, a single intravenous bolus dose should be administered within 60 min before the surgical incision. An additional dose should be given in case of hemorrhage or prolonged surgery, according to the half-life of the drug. Factors such as the patient’s weight, history of allergies, and the likelihood of colonization by resistant bacteria should be considered. Compliance with institutional protocols enhances the effectiveness of antibiotic use. CONCLUSION: Surgical antibiotic prophylaxis is associated with reduced rates of surgical site infection, hospital stay, and morbimortality.

This paper includes an analysis of academic papers that focus on cultural aspects written by MA students in the ‘Teach & Learn in Spain’ program at Instituto Franklin-UAH. The percentage of academic papers focusing on cultural aspects written by these students who acted as Language Assistants (LAs) in bilingual schools in Spain is quite high. This suggests the importance of the cultural component in the teaching of English as a second language and their high level of sociocultural awareness. Thus, this paper has several objectives: a) to determine the existence of a specific sociocultural awareness in research papers; b) to identify the cultural aspects that were considered essential by the LAs in this program and show the strategies used to provide information; and c) to compare findings considering the theoretical background. The method will rely on a mixt approach considering quantitative and qualitative analyses and will be specific for each of the objectives.
