As it is environmentally sensitive, the pulp and paper sector carry out social and environmental actions to mitigate the negative effects of production. Socioenvironmental evidence is the strategy that companies use to demonstrate social and environmental actions; therefore, this study aims to analyze the evolution of socioenvironmental evidence of Brazilian pulp and paper companies. To this end, the content of the sector’s sustainability reports, published in the Global Reporting Initiative database, was analyzed. Data were processed through descriptive statistics and multiple factor analysis. The results show that the pattern of evidence is similar among companies. The environmental category was the most evident; however, there was a decline in disclosure levels from 2013, especially for the product responsibility category.

Air pollution is one of the main environmental risk factors for health and is linked to cardiovascular diseases, which are the leading cause of mortality worldwide.In this position paper, we discuss the main air pollutants and how they can promote the development of cardiovascular disease or cardiovascular events. We also summarise the main evidence supporting the association between air pollution and cardiovascular events, such as coronary events (acute coronary syndromes/myocardial infarction; chronic coronary syndromes), stroke, heart failure and mortality. Some recommendations are made based on these data and the European Society of Cardiology guidelines on cardiovascular disease prevention, acknowledging that it is important to increase awareness and literacy on this topic in Portugal. Resumo: A poluição do ar é um dos principais fatores de risco ambiental para a saúde e está associada à principal causa de morte em todo o mundo que são as doenças cardiovasculares. Neste position paper discutimos a forma como os principais poluentes atmosféricos podem promover o desenvolvimento de doenças ou eventos cardiovasculares. Também agregámos a melhor evidência que suporta a associação entre poluição do ar e eventos cardiovasculares, como eventos coronários (síndromes coronárias agudas/enfarte do miocárdio; síndromes coronárias crónicas), acidente vascular cerebral, insuficiência cardíaca e o risco de morte. Foram feitas recomendações de acordo com a evidência, os dados nacionais e as orientações da Sociedade Europeia de Cardiologia sobre prevenção de doenças cardiovasculares, reconhecendo que é importante aumentar a sensibilização e literacia sobre este tema em Portugal.

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 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.

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.

This article discusses Conservation Units in the conservationist perspective, as instruments to protect nature, assuring the maintenance of Brazilian biodiversity and biomes, in order to build an ecologically balanced environment under the terms of the Federal Constitution of 1988. Through deductive method, exploratory, documental, and bibliographic research, and indirect analysis of Environmental Ministry and Environmental, Sustainable Development State Office data, it makes a legal-theoretical appreciation of the issue in Brazil. By looking at the Brazilian scenario, it notices that most part of the Conservation Units were created by the States and were focused, respectively, on Mata Atlântica, Cerrado, and the Amazon, and had sustainability as a legal-political fundament. The conjuncture of Goiás indicates that stating the Conservation Units existence is not enough, since more than half of Conservation Units lack landing regularization. Also, six out of twenty-five Conservation Units still do not have an Administrative Counsel. Twenty Conservation Units do not have a working plan, which, added to financial and staff difficulties may compromise the expected protection of nature. [ABSTRACT FROM AUTHOR]

ABSTRACT: The growing worldwide demand in the pulp market has fostered research that evaluates alternative fiber sources with specific characteristics that attend the needs of the consumer market, with a view to add value to the final product and reduce production costs. Acacia mearnsii De Wild wood is a by-product of the extraction of tannin from the trunk bark, used for firewood, charcoal and pellets. However, its wood is still poorly studied, especially its anatomical characteristics, which can provide important information about its industrial potential. This study evaluated the anatomical characteristics of Acacia mearnsii wood for the production of pulp and paper. Ten trees at approximately seven years old were cut down, five from the seed production area (SPA) and five from the clonal population area (CPA). From each tree, one trunk disc was sectioned at the diameter at breast height (DBH), resulting in 10 (ten) wood samples. From each disc, a sapwood specimen was made oriented in the tangential longitudinal, radial longitudinal and transversal planes, for later obtaining the anatomical cuts and the macerates. The anatomical description of the wood followed the recommendations of the International Association of Wood Anatomists-IAWA. From the dimensions of the fibers, their quality evaluation ratios for the production of pulp and paper were calculated. Results obtained from the anatomical characterization allowed to conclude that the Acacia mearnsii woods from SPA and CPA are indicated as a source of raw material for the pulp and paper production.

There have been new facets of multilateralism, which have motivated the realignment of traditional power relations established globally, especially regarding the United States and China. This new strategic environment can be observed in changes made to the Brazilian National Defense White Paper (LBDN) of 2020, as well as in the dialectic between white papers of the United States (2017), and China (2019). To investigate these realignments and their possible impacts on the Brazilian defense sector, the analysis was carried out in two phases: (1) analysis of the general characteristics of the Defense White Papers by the USA and China; and (2) comparison of discourses conveyed in chapters on international cooperation in each Defense White Paper. Speech patterns were analyzed according to rationales of Lexical Semantics and Critical Discourse Analysis. As a result, elements of semantic fields, intertextuality and modality in discourse were pointed out as parameters that could contribute to the evaluation of cooperation and deterrence/dissuasion actions to be adopted by the USA and China in the 21st century.

La práctica artística contemporánea tuvo un espacio de reflexión y creación de opinión en las páginas de Papers d’Art. De la mano de un conjunto de voces propias e independientes se visibilizaron formas de producción artística multidisciplinarias, desde la perspectiva divulgadora de una crítica que conectaba dinámicamente los significados artísticos con los sociales y culturales. Conviene resaltar el desplazamiento del significado de la concepción del arte contemporáneo en calidad de pieza clave en la cultura intelectual, incluyendo política, filosofía, ciencia u otros formatos de creación como la música y la literatura. Partiendo del análisis de la conciencia crítica de los diferentes colaboradores y la investigación historiográfica en torno a cuestionamientos estéticos y simbólicos, se despliega una revisión del conjunto de los discursos incluidos en la sección Estudios e Investigación. Palabras clave: Fundació Espais; Papers d’Art; crítica de arte catalana; investigación universitaria sobre arte contemporáneo; perspectiva divulgadora del arte. Papers d’Art. Contents of the Study and Research section Abstract: Contemporary artistic practices were provided with a space for reflection and the creation of opinion in the galleries of the Fundació Espais and in the pages of its art magazine, Papers d’Art. A group of independent voices of multidisciplinary artistic production was made audible thanks to this publication that provided a critique which forged dynamic connections between artistic meaning and social and cultural contexts. This paper highlights a shift in meaning of the conception of contemporary art as a key element in intellectual culture, including politics, philosophy, science and other creative formats such as music and literature. Based on an analysis of the critical awareness of the various contributors to the magazine and on the historiographic study of certain aesthetic and symbolic questions, a review of the articles published in the Studies and Research section is detailed.

The article presents in detail the genesis of the Monteiro Lobato Fund, at CEDAE/Unicamp, covering from the initial project to the development of the Archive over the years. Some sections are more explicit, such as letters (some transcribed), photographs, books and presence in the media. It highlights its role for a more complete knowledge of the audiences and backstage of Brazilian literary history of the beginning of the 20th century, beyond the current stereotypes about the writer.

This study investigates the linguistic organization of the introduction sections of academic papers from the Veterinary Medicine field in terms of the two basic systems that determine how one clause is related to another: taxis (degree of interdependency) and logico-semantic relation (Halliday; Matthiessen, 2014, p. 438). All the clauses from the introduction sections of five published academic papers were analyzed. The results showed a high recurrence of simple clauses and embedded clauses in the corpus. In the clause complexes, the preference is for paratactic extensions. The results of this analysis may help understanding the functioning of academic writing in English language in this specific field.

Abstract The study extends the conversation on the effect that co-authorship has on the citation impact of papers by analyzing the short-term advantage of co-authored papers. The results suggest that co-authored papers have a higher short-term impact than single-authored ones in all scientific domains. The study adds insights on the use of the immediacy index as an alternative indicator to evaluate the short-term competitive advantage of co-authored papers concerning the number of citations they attract. Furthermore, the study shows the efficacy of the immediacy index in comparing the short-term impact of different groups.

The pulp and paper sector has a notable highlight in the Brazilian economy, contributing significantly to the trade balance, job creation and investments. Currently, the sector basically uses wood from two genus to produce pulp for the short fiber and long fiber segments, Eucalyptus and Pinus, respectively. However, it's essential to study new raw materials, which may arise as an alternative to those already consolidated. In this sense, the objective is to evaluate the properties of Liquidambar styraciflua wood for the pulp and paper production. For this, five 7-year-old trees were used, from which discs were extracted along the trunk to evaluate the basic density, chemical composition and morphology of the wood fibers. The mean and weighted basic density values obtained for L. styraciflua wood were 0.482 and 0.484 g/cm², respectively, which allowed classifying it as medium density, a value close to that of other hardwood species used for pulp production. Regarding the chemical composition, low levels of ash (0.29%) and lignin (24.71%) and high levels of holocellulose (70.88%) and extractives (4.40%) were observed. As for the morphological characterization of the fibers, the mean values of length of 1.82 mm, width of 27.84 µm, lumen diameter of 16.10 µm and wall thickness of 5.87 µm were observed. In addition, mean values of 42.60%, 57.40%, 0.77 and 65.22 were obtained for the parameters of wall fraction, flexibility coefficient, Runkel index and felting index, respectively. In general, based on the physical-chemical-anatomical characteristics obtained for the L. styraciflua wood, it's concluded that it has aptitude for the pulp and paper production.

L’objectiu d’aquest article és estudiar la importància que té l’arxiu com a eina de construcció d’una identitat nacional i si a través de la seva organització es pot veure si la dita construcció nacional ha estat reeixida o no. En aquest sentit, s’agafa l’exemple de l’Arxiu Històric Nacional d’Espanya i s’analitza des de l’organització dels primers arxius en territori espanyol fins a la construcció de l’Arxiu Històric Nacional a finals del segle xix. Mitjançant aquesta anàlisi també es posa en relleu el paper que va tenir la Història en la formació de la identitat nacional i la seva interrelació amb l’arxiu. Una ciència no podria ser sense l’altre.

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., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

This data paper presents the creation of a database bringing together all the French municipalities while giving a specific place to those which have undergone a merger process between 2012 et 2022: "the new municipalities" (communes nouvelles). Potential data gap and consistency issues arise with the creation of these new territorial entities aggregating municipal mergers. Using data from official statistics (INSEE - National Institute for Statistics and Economic Studies - and IGN - National Geographic Institute), this paper describes a process of compilation and aggregation of data. The method is detailed here, to allow its reproducibility.

Heart failure (HF) with reduced ejection fraction (HFrEF) is associated with high rates of hospitalization and death. It also has a negative impact on patients’ functional capacity and quality of life, as well as on healthcare costs. In recent years, new HFrEF prognosis-modifying drugs have emerged, leading to intense debate within the international scientific community toward a paradigm shift for the management of HFrEF. In this article, we report the contribution of a Portuguese HF expert panel to the ongoing debate.Based on the most recently published clinical evidence, and the panel members’ clinical judgment, three key principles are highlighted: (i) sacubitril/valsartan should be preferred as first-line therapy for HFrEF, instead of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker; (ii) the four foundation HFrEF drugs are the angiotensin receptor/neprilysin inhibitor, beta-adrenergic blocking agents, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter 2 inhibitors, regardless of the presence of type-2 diabetes mellitus; (iii) these four HFrEF drug classes should be introduced over a short-term period of four to six weeks, guided by a safety protocol, followed by a dose up-titration period of 8 weeks. Resumo: A insuficiência cardíaca (IC) com fração de ejeção reduzida (ICFEr) está associada a níveis elevados de hospitalização e mortalidade. A ICFEr também tem um impacto negativo na capacidade funcional e na qualidade de vida dos doentes, bem como na despesa em saúde. Nos últimos anos, surgiram novos medicamentos modificadores do prognóstico da ICFEr, originando um intenso debate na comunidade científica internacional em relação a uma mudança de paradigma para o tratamento da ICFEr. Neste artigo, relatamos a contribuição de um painel de especialistas portugueses em IC para o debate em curso.Com base na evidência clínica publicada mais recentemente e no julgamento clínico dos membros do painel, três princípios-chave são destacados: (i) sacubitril/valsartan deve ser preferido como terapia de primeira linha para a ICFEr, em vez de um inibidor da enzima de conversão da angiotensina ou um bloqueador do recetor da angiotensina; (ii) os quatro medicamentos básicos para a ICFEr são o inibidor do recetor da angiotensina e da neprilisina, os agentes bloqueadores beta-adrenérgicos, os antagonistas do recetor mineralocorticoide e os inibidores do cotransportador sódio-glucose 2, independentemente da presença de diabetes mellitus tipo 2; (iii) essas quatro classes de medicamentos para a ICFEr devem ser rapidamente introduzidas num período curto de 4-6 semanas, seguindo um protocolo de segurança, e depois tituladas durante as oito semanas seguintes.
