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.

Mitigation of fungal biodeterioration on paper documents and artworks represents a challenge to conservators worldwide. Numerous lists of fungal species have been identified from paper collections, but are those species responsible for the respective biodeterioration phenomena or just environmental contaminants? The present work was aimed at obtaining an association between specific fungal stains and causative fungal species. 23 stains from three paper documents were sampled. Fungal structures observed in situ with optical and scanning electron microscopy were compared with the identification of isolates by molecular biology tools. Correlation between the observed fungal structures and the identified fungal isolates was achieved, varying from 13% to 64% of the samples within the three studied documents. Grey/black and dark brown stains were associated with Chaetomium globosum, C. murorum, Penicillium chrysogenum, P. commune, Myxotrichum deflexum and Stachybotrys chartarum. Eurotium rubrum was isolated from a foxing stain and Penicillium citrinum was identified on light orange stains.

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.

Cardiovascular (CV) guidelines stress the need for global intervention to manage risk factors and reduce the risk of major vascular events. Growing evidence supports the use of polypill as a strategy to prevent cerebral and cardiovascular disease, however it is still underused in clinical practice. This paper presents an expert consensus aimed to summarize the data regarding polypill use. The authors consider the benefits of polypill and the significant claims for clinical applicability. Potential advantages and disadvantages, data regarding several populations in primary and secondary prevention, and pharmacoeconomic data are also addressed., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

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.

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.
