ABSTRACT Coronary artery calcification is probably the main determinant of the poor outcome of percutaneous coronary interventions and is associated with higher rates of adverse events. There are currently different balloon or specific device-based plaque modification techniques available. Knowing their characteristics and proper use is key for the optimal treatment of calcified lesions. This position paper—promoted by the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC)—describes existing plaque modification techniques currently available and proposes an algorithm for the management of calcified lesions.

Four organic solid wastes (coffee grounds, ground nut shell, paper money sewage sludge and cork powder) have been investigated as bloating inducing agents in lightweight aggregate (LWA) manufacturing when mixed in small proportions (2.5 wt.%) with three types of clays. The pellets obtained were fired in a rotary kiln at the maximum feasible temperature for 4 min. A similar impact was observed both in the working conditions and in the properties of the LWAs, showing that the differences between said residues are not as decisive as those of the clays to which they are added. The organic wastes have played a crucial role in achieving reducing conditions inside the aggregate. Thus, their addition has led to substantial improvements both from an operational point of view, lowering the working temperature, and from a technological perspective, favoring bloating and the development of a highly porous and lightweight structure. Leachate studies have shown that the LWAs meet the regulatory limits. The outcomes of this investigation show that, in line with the precepts of the Circular Economy, the recovery of organic wastes of different nature can have a place in the production of environmentally friendly LWAs. Resumen: Se han investigado cuatro residuos sólidos orgánicos (posos de café, cáscara molida de frutos secos, lodos de depuradora de papel moneda y polvo de corcho) como agentes expansivos en la fabricación de áridos ligeros (LWAs) al mezclarse en pequeñas proporciones (2,5 wt.%) con tres tipos de arcillas. Los pellets conformados se han cocido en un horno rotatorio a la máxima temperatura viable durante 4 min. Se observó un impacto similar tanto en las condiciones de trabajo como en las propiedades de los LWAs, mostrando que las diferencias entre dichos residuos no son tan influyentes como las de las arcillas a las que se añaden. El componente orgánico ha jugado un papel crucial en la consecución de las condiciones reductoras dentro del árido. Así, su adición ha supuesto mejoras sustanciales tanto desde el punto de vista operativo, reduciendo la temperatura de trabajo, como desde una perspectiva tecnológica, favoreciendo la expansión y el desarrollo de una estructura altamente porosa y ligera. Por otro lado, los LWAs obtenidos cumplirían con los límites reglamentarios de lixiviación de metales pesados. Se demuestra que la valorización de residuos orgánicos de distinta naturaleza puede tener cabida en la producción de LWAs respetuosos con el medio ambiente.

In the face of the premonitions that pointed to its obsolescence and lethal decline due to the hegemonic digital paradigm, the (hyper)contemporary novel has demonstrated a strong capacity for reinvention and rejuvenation, exploring, for example, the materiality and visuality of the printed page. This occurs in the multimodal novel, the narrative subgenre that we intend to characterize. We highlight its strong archival propensity and adduce the reasons that drive the multimodal narrator to integrate and semantically explore resources other than just words (e.g., images, documents, objects, etc.). Starting from this theoretical section, our main objective is to analyze the portuguese novel A Coleção Privada de Acácio Nobre (2016), by Patrícia Portela. This multimodal work presents the "spolio" of Acácio Nobre, an important artist (1869-1974), but shrouded in an aura of silence and, therefore, practically unknown to all. In order to demonstrate his real existence, various types of documentary evidence (photographs, manuscripts, drawings, works of art, and others) are inserted. It is our intention to analyze the various strategies of veridiction and fictionalization deployed by the narrator in the construction of the Acacian figure. In addition, we also consider the possibility of Acácio Nobre (along with Bernardo Soares, his friend) being a semi-heteronym.

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.

This paper aims to inquire for the sociodemographic structure of the Venezuelan occupied labour force and its differences in comparison to the national occupied labour force in the city of Bogotá, Colombia. To achieve this purpose, this research relies on data for the year 2021 from the Integrated Great Survey of Households (Gran Encuesta Integrada de Hogares - GEIH), a monthly socio demographic survey GEIH that captures information related to the main characteristics of the studied population. In this sense, comparisons in terms of educational levels, income, occupational status, family structure, gender and age groups were done in order to determine differences and common patterns. Finally, a hierarchical cluster analysis strategy was proposed to identify possible sociodemographic typologies of the Venezuelan labour force.

Prenent en consideració el paper actual i futur de la intel·ligència artificial en la licitació pública, el present article es centra, des de l’òptica de les directrius de la Llei 15/2022, integral per a la igualtat de tracte i la no-discriminació, en la potencialitat que pot correspondre a la intel·ligència artificial davant la detecció i l’actuació contra les col·lusions en la contractació pública. Dins d’aquest nou dret computacional de la competència o “antitrust 3.0” es detallarà el paper capdavanter que ha assumit l’Autoritat Catalana de la Competència (ACCO) pel que fa a la posada en marxa, en fase experimental, de l’eina informàtica ERICCA, i, en paral·lel, la seva participació activa dins del projecte Computational Antitrust del Stanford Center for Legal Informatics (CodeX).

It is estimated that more than 500 species of insects have been introduced to the Galápagos Islands via human activities. One of these insect invaders is the yellow paper wasp, Polistes versicolor (Olivier) (Hymenoptera: Vespidae), a social wasp native to continental South America. In Galápagos, these wasps are voracious predators of insect larvae, compete with native species for insect prey or for floral resources and are a human nuisance. Wasp suppression methods currently in use are inefficient and attract non-target species, calling for the development of species-specific attractants that can be used in baits to lure and kill wasps. To evaluate the potential for using wasp semiochemicals in baits, we determined the biochemical composition of the head, thorax, Dufour’s and venom glands of P. versicolor foragers via gas chromatography/mass spectrometry (GC/MS). Male and female wasps were tested for behavioral responses to body segment extracts from both sexes. Female body extracts consistently elicited more behavioral responses in both male and female wasps than male extracts. Females reacted to female head, thorax and abdomen (the Dufour’s and venom glands are located in the abdomen) extracts, whereas males reacted significantly to female head and thorax extracts. One male body extract, the head, elicited two significant behaviors: female wasps groomed more often, and males touched the filter paper more often compared to the blank control. Head extracts consistently changed the behavior of female and male wasps and, together with female thorax extracts, have potential as species-specific lures for yellow paper wasps. Heads were mainly composed of hydrocarbon lipids and oleamide, a ligand for odorant-binding proteins. The thorax consisted of fatty aldehydes, long-chain alkanes and fatty amide lipids. Field trials of blends of these compounds in high wasp density areas of Galápagos are the next step to confirm if any of these compounds are attractive to P. versicolor.

Objective: The need to generate evidence related to COVID-19, the acceleration of publication and peer-review process and the competition between journals may have influenced the quality of COVID-19 papers. Our objective was to compare the characteristics of COVID-19 papers against those of non-COVID-19 papers and identify the variables in which they differ. Method: We conducted a journal-matched case-control study. Cases were COVID-19 papers and controls were non-COVID-19 papers published between March 2020 and January 2021. Journals belonging to five different Journal Citations Reports categories were selected. Within each selected journal, a COVID-19 paper (where there was one) and another non-COVID-19 paper were selected. Conditional logistic regression models were fitted. Results: We included 81 COVID-19 and 143 non-COVID-19 papers. Descriptive observational studies and analytical observational studies had, respectively, a 55-fold (odds ratio [OR]: 55.12; 95% confidence interval [95%CI]: 7.41-409.84) and 19-fold (OR: 19.28; 95%CI: 3.09-120.31) higher likelihood of being COVID-19 papers, respectively, and also a higher probability of having a smaller sample size (OR: 7.15; 95%CI: 2.33-21.94). COVID-19 papers had a higher probability of being cited since their publication (OR: 4.97; 95%CI: 1.63-15.10). Conclusions: The characteristics of COVID-19 papers differed from those of non-COVID-19 papers published in the first months of the pandemic. In order to ensure the publication of good scientific evidence the quality of COVID-19-papers should be preserved. Resumen: Objetivo: La necesidad de generar evidencia relacionada con la COVID-19, la aceleración del proceso de revisión por pares y publicación, y la competencia entre revistas, pueden haber influido en la calidad de los artículos sobre la COVID-19. El objetivo fue comparar las características de los artículos sobre la COVID-19 con las de los artículos no COVID-19 e identificar las variables en las que difieren. Método: Se realizó un estudio de casos y controles emparejados por revista. Los casos eran artículos COVID-19 y los controles eran artículos no COVID-19 publicados en el mismo periodo. Se seleccionaron revistas pertenecientes a cinco categorías diferentes del Journal Citations Reports. Dentro de cada revista seleccionada, se escogió un artículo COVID-19 (cuando había uno) y otro artículo no COVID-19. Se ajustaron modelos de regresión logística condicional. Resultados: Se incluyeron 81 artículos COVID-19 y 143 artículos no COVID-19. Los estudios observacionales descriptivos y los estudios observacionales analíticos tenían, respectivamente, una probabilidad 55 veces mayor (odds ratio [OR]: 55,12; intervalo de confianza del 95% [IC95%]: 7,41-409,84) y 19 veces mayor (OR: 19,28; IC95%: 3,09-120,31) de ser artículos COVID-19 y de tener un tamaño de muestra menor (OR: 7,15; IC95%: 2,33-21,94). Los artículos más citados desde su publicación tenían 5 veces más probabilidades de ser artículos COVID-19 (OR: 4,97; IC95%: 1,63-15,10). Conclusiones: Los artículos COVID-19 parecen tener mayor impacto bibliométrico, a pesar de tener menor calidad metodológica. Para asegurar la publicación de buena evidencia científica se debe preservar la calidad de los artículos relacionados con la COVID-19.

Objective: To provide a working guide which facilitates the accuracy, transparency, and usefulness for academics and practitioners of case report papers as an article type which are fit for publishing in impact journals. In this way, we aim to increase the use and dissemination of recommendations in aid of the writing and publication of case study and action research. Theoretical framework: A case report paper presents a story in narrative form and includes current individual or organisational concerns, situational diagnoses, interventions, outcomes including adverse events, and follow-up. The narrative should include a discussion of the rationale for any conclusions and lessons learned. Method: We analysed the prevalence of these type of articles in publications as indexed in Web of Science (WOS) and in Scopus; we explain how we customised the case report guidelines (CAse REport or CARE) to optimise them for the scientific field of Management focussing particularly on Operations Management and Human Resources Management. We shared for discussion and feedback the adapted proposal among a group of academics and professionals in the field of Management. Outcomes/Implications: Robust reporting guidelines help to improve research performance, reduce bias risk, provide information on the implementation of management practices, support the training of management professionals, and enable informed editorial decisions by journal editors and reviewers.

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.

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.

In order to study the feasibility of kraft paper as watercolor paper, the wetting properties, mechanical properties and friction properties of kraft paper and watercolor paper were compared before and after aging. Aging test was carried out on kraft paper and watercolor paper by aging chamber, the wetting properties of distilled water and three watercolor solutions before and after aging of kraft paper and watercolor paper were compared, tensile tear test of paper on tensile testing machine, the fracture changes of paper were analyzed by scanning electron microscope, the friction tester performs the paper friction test. The results show that both kinds of paper are amorphous, watercolor paper was showed hydrophobicity before and after aging, contact angle was maintained at about 119,09° ± 5° in four different solutions, unaged kraft paper exhibited hydrophilicity, the aged kraft paper showed hydrophobicity with a contact angle of 92,52° ± 1°，the aged kraft paper shows better performance in both tensile and tearing aspects and tensile strength is 20 MPa higher than watercolor paper, surface roughness of kraft paper is higher than watercolor paper. The experiment is helpful for the market to consider whether the cheaper kraft paper replaces the more expensive watercolor paper in some aspects and provides some scientific reference value for the future research.

The concept of mock-up, which share with the drawing the expressive synthesis for the analysis of the architectural form and evolution, is an invaluable asset for the preservation of the heritage. To mark the 175th anniversary of the Práxedes Mateo Sagasta’s secondary school of Logroño (Spain), an exhibition about the history of the institution was organized at the premises of La Rioja Library. The current school building became operational in 1900 and was built on the former site of a Carmelite convent. In fact, the convent rooms were the first location for the school, after the expropriations of religious communities during the mid-19th century. For the benefit of the aforementioned exhibition, it was considered interesting to generate a three-dimensional (3D) virtual reconstruction of the convent buildings to show how it would have looked. However, the lack of sufficient contemporary graphic information was a challenge, so it was decided that an efficient solution would be to generate the virtual reconstruction from a paper craft model, which had been created by the librarian of the secondary school as a result of his research on this matter. This text describes the 3D modelling of that cut-out element by means of monoscopic photogrammetry (perspective drawing) and the use of non-realistic rendering based on the appearance of the paper mock-up (and not trying to recreate the real image of the buildings) so as to provide a suggestive view of the convent and create interactive exhibition items. Moreover, the text deals with the long-term preservation and the improvement of the re-use of the 3D models. The former by resorting to institutional repositories —from which users can download the full detailed versions— and the latter employing versions able to be visualized in 3D warehouses (such as Sketchfab) and augmented reality (AR) applications. Highlights: • A significant part of the architectural heritage is represented by mock-ups of different materials (paper, wood, metal and so on). • Virtual modelling and augmented reality (AR) can be appropriate tools for materializing, recovering and disseminating scale models to the public. • Techniques for geometric documentation and visual representation need to be adapted in order to tackle the peculiar features of these elements (size, materials, fragility, etc.).

Similar to many other countries, journalistic production in China during the first half of 2020 was dominated on a thematic level by the COVID-19 pandemic. The trend included the mouthpiece of the Central Committee of the Chinese Communist Party (CCP), Renmin Ribao. Its news and commentary articles, which are widely republished by other media, influence the country’s political life, and contribute to the process of meaning generation in the news discourse and to the CCP’s effort to align Chinese citizens to official narratives. Renmin Ribao can therefore provide a relevant source to investigate the relationship between political power and the COVID-19 pandemic, starting from the hypothesis that the paper’s narrative would aim at discursively turning the international health crisis into a piece of positive propaganda. This study aims to verify whether and how the paper did so, and to question the assumption that the outlet’s media discourse can be equated to the CCP official discourse. The research is developed as a case study and blends quantitative and qualitative tools grounded on Applied Linguistics, Discourse-Historical Approach, and Frame Analysis, in order to analyse a corpus of commentaries that have appeared in the outlet’s online edition in 2020. By applying a Genre Analysis approach, the study also offers insights into the possibility to identify distinguishing characteristics and communicative goals in the different sub-genres of Renmin Ribao commentaries.

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.

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.

A multi-modal search space can be defined as having multiple attraction basins – each basin has a single local optimum which is reached from all points in that basin when greedy local search is used. Optimization in multi-modal search spaces can then be viewed as a two-phase process. The first phase is exploration in which the most promising attraction basin is identified. The second phase is exploitation in which the best solution (i.e. the local optimum) within the previously identified attraction basin is attained. The goal of thresheld convergence is to improve the performance of search techniques during the first phase of exploration. The effectiveness of thresheld convergence has been demonstrated through applications to existing metaheuristics such as particle swarm optimization and differential evolution, and through the development of novel metaheuristics such as minimum population search and leaders and followers.
