A submissão pela raça e o imaginário social brasileiro
Authors: Roberto Costa Candido Marcos
Published: November 2023

O presente trabalho tem por objetivo analisar o fundamento da discriminação racial supostamente autorizadora do processo de escravidão do século XV e suas implicações no imaginário social brasileiro contemporâneo. Verificou-se que esse imaginário permitiu a caracterização de novas formas de racismos, notadamente aquele arraigado de forma estrutural na sociedade. A superação desses racismos, concluiu-se, passa primordialmente pela educação, não só por meio da disseminação do conhecimento, mas também pela superação do racismo epistêmico.
Agências negras na arte brasileira
Authors: Campos da Silva Thiago
Published: November 2023

O objetivo deste artigo é avaliar a inserção de artistas negros na Escola Nacional de Belas Artes (ENBA) no Rio de Janeiro da Primeira República (1889-1930), tendo como recorte a trajetória do pintor João Timotheo da Costa (1879-1932). Para realizar essa tarefa, será mobilizada a historiografia que debate a presença negra nos estudos da arte brasileira, com destaque para o final do século XIX e o início do século XX; além disso, as informações sobre João Timotheo da Costa foram reunidas a partir da pesquisa bibliográfica e do levantamento nos jornais cariocas do período estudado. A relevância dessa delimitação é investigar a experiência social de um pintor negro que frequentava as instituições oficiais e circulava pelas redes de sociabilidade da belle époque carioca a partir de uma perspectiva voltada às relações raciais.
Crítica política e social na ditadura militar brasileira
Authors: Aparecida Cezario Maria , Batista Ferreira Kaliene
Published: November 2023

O presente ensaio tem como objetivo uma análise da história da música Apesar de Você, de Chico Buarque de Holanda, produzida no ano de 1970. Trata-se de uma melodia feita pelo cantor durante o período mais rigoroso da ditadura militar brasileira (1964-1985). Nesse sentido, a canção tem como pressuposto fazer uma crítica aos atos de repreensão que estavam acontecendo no período da ditadura militar, uma vez que o país estava sendo governado pelo presidente o general Emílio Garrastazu Médici. Tendo em vista que o Ato Institucional n° 5, conhecido como AI-5, foi decretado no governo de Artur da Costa e Silva e posto em prática no governo de Médici, tal época foi marcada por momentos de perseguição, tortura, assassinatos, censura e exilio. Diante disso, o estudo visa levantar e discutir algumas questões que a música denunciava, como os problemas políticos e sociais e como era caracterizado esse processo de redemocratização no Brasil após o período da ditadura civil militar.
As mulheres e a Segunda Guerra Mundial
Authors: Clara Félix de Souza Anna
Published: November 2023

Com a entrada dos Estados Unidos na Segunda Guerra Mundial, o recrutamento de soldados tornou-se indispensável para a participação ativa no caminho da vitória para os Aliados. Contudo, no território norte-americano, com a ida dos homens à guerra, houve, imediatamente, uma escassez de mão-de-obra. Logo, foi percebido que essa lacuna trabalhista poderia ser preenchida pelas mulheres norte-americanas, população remanescente do país no momento. A partir disso, o governo americano iniciou um projeto de iniciativa de adesão das mulheres ao setor industrial, por meio das propagandas. Desse movimento, a iconografia “Rosie, the Riveter” foi o símbolo da inclusão das mulheres no mercado de trabalho, sendo até hoje utilizada para diálogos com esse fim.
La percepción de la toma de decisiones a través de inteligencia artificial cuando se produce daño a las personas
Authors: Espinosa Pablo , Clemente Miguel
Published: November 2023

La toma de decisiones en inteligencia artificial (IA) puede ocurrir en escenarios en los que se decide en una fracción de segundo sobre la vida o el bienestar de los individuos sin que medie supervisión humana. Los algoritmos de IA que se aplican en estos casos pueden basarse o bien en criterios deontológicos o utilitaristas. Incluso si hubiese un consenso ético sobre la toma de decisiones de la IA, si la gente no encontrase aceptables los criterios éticos de la IA, su rechazo dificultaría su implementación. Por ejemplo, si un coche autónomo siempre sacrificase la seguridad de sus pasajeros antes que poner en peligro a otras víctimas en un accidente inevitable, mucha gente no compraría un coche autónomo. En este artículo se realiza una revisión bibliográfica de artículos científicos del ámbito de la psicología social sobre las variables implicadas en la percepción de decisiones relacionadas con la IA. Esta percepción social de la IA puede tener relevancia en el desarrollo de criterios sobre la responsabilidad legal. Finalmente, se examinan aspectos relacionados con el ámbito jurídico con la utilización de la IA en el sistema judicial y en la comisión de delitos.
Le territoire agroalimentaire en tant qu’attrait touristique au Québec
Authors: Tavares de Souza Ronaldo , Marcotte Pascale , Bourdeau Laurent
Published: November 2023

Les produits du terroir sont caractérisés par la singularité que leur donne le territoire d’où ils sont issus. Cette singularité est utilisée dans leur promotion, mais elle peut également susciter l’intérêt des individus pour ce territoire. Né en Europe et d’abord appliqué au vin, le concept de terroir est depuis lors en expansion. Il est utilisé partout dans le monde, et pour une diversité de produits. Toutefois, son utilisation hors de l’Europe pose la question de la manière dont ce concept s’applique ailleurs, et de son lien avec le tourisme. Cet article vise à comprendre comment les offres agroalimentaire et touristique s’intègrent et peuvent contribuer à la construction de l’image du terroir au Québec. L’analyse de contenu lexical et des images des pages Web des organismes de gestion de la destination, des associations d’agrotourisme et de tourisme gourmand locales et des entreprises agroalimentaires de deux régions québécoises indique que le terroir est surtout un synonyme de « produit local ». Son utilisation n’a pas pour but de souligner la singularité qu’a un produit en fonction de son territoire de production. Un modèle d’orchestration des éléments représentatifs du territoire pour contribuer à la mise en valeur de la destination gourmande est suggéré. Deux voies de développement sont proposées : une production spécifique et une généraliste. Bien que le tourisme gourmand soit déjà important dans les destinations étudiées, il pourrait y être davantage intégré à l’aide d’une communication coordonnée entre les acteurs impliqués.
Ushinsky and the Russian school: an unproven axiom or an unsolved problem
Authors: Metlik Igor
Published: November 2023

Ushinsky's creative legacy on the content of upbringing and teaching children in a Russian comprehensive school is considered in the article as a methodological tool for researching and evaluating the state of modern Russian schools, historical and spiritual and moral education, teaching Orthodox culture. The "Ushinsky axiom" is formulated: a folk school should give children knowledge about their homeland and religion, the spiritual and moral culture of their people as the first and necessary knowledge. The article provides a brief overview of the development of the situation with the teaching of Orthodox culture in the last decade, after the principal decision to restore the possibility of religious (confessional) spiritual and moral education according to the choice of parents of students in the Russian school in 2009, to the present. Based on the work of Ushinsky, in solving the problem of adequate study of history and culture of Russia and the traditional spiritual culture of the people by schoolchildren, the main acting factors are highlighted. The main positive factor in solving the problem is the educational demand of society, citizens for the study of traditional spiritual and moral culture by their children at school, the parameters and quality of this request. The negative factor of counteraction to the solution of the problem is formed in society, in the educational system on the basis of indifference or negative attitude, primarily to religion, traditional spiritual culture of the Russian and other peoples of Russia. The conclusion is substantiated that any reform of the school, general education should provide for the full study of the history and culture of Russia by schoolchildren, historical education, guarantees for the study of the traditional spiritual culture of the peoples of Russia at the choice of their families, parents at all levels of general education.

Інтегральний підхід дав змогу використовувати дводискову імпульсну модель для визначення основних питомих показників системи. Коефіцієнт потужності розраховувався на основі знайденого значення коефіцієнта крутного моменту на валу, який, у свою чергу, визначався числовим інтегруванням інтеграла повного крутного моменту, створюваного вітровою турбіною. Для розрахунку тестової задачі використовувалися класичні аеродинамічні профілі NACA: 0012, 0015, 0018, 0021. Запропонований алгоритм розрахунку дає змогу не вказувати на початку розрахунку число Рейнольдса та відповідні аеродинамічні коефіцієнти, а перераховувати їх залежно від відносної швидкості, положення профілю та лінійної швидкості профілю по колу.
Self e identidade pessoal
Authors: Peruzzo Júnior Léo , Stroparo Amanda
Published: November 2023

Este artigo pretende mostrar, a partir de uma leitura das hipóteses da mente estendida de Andy Clark e de sua absorção das consequências funcionalistas, que os conceitos de self e identidade pessoal se encontram naturalmente diluídos no corpo e no mundo. Defenderemos com estas premissas que o movimento operado pela integração da proposta de Clark com o self autobiográfico de Richard Heersmink e a teoria padrão do self de Shaun Gallagher é um movimento de hibridização, que dá origem à imagem de um self ecológico e multifacetado, assim como de uma noção mais permeável acerca da identidade pessoal. Afinal, enquanto Clark lança luz aos movimentos funcionalistas que estendem a mente e o self no mundo, Heersmink enfatiza o papel da auto-narrativa no design do self, assim como o caráter socialmente estendido do self e as relações entre este e a identidade pessoal. Gallagher, por sua vez, reitera a relevância tanto desta dimensão social quanto da concepção de uma tese que expresse essa matização. Mais especificamente, teremos neste processo a emergência de um self híbrido.
Avicena e o problema do sujeito da metafísica
Authors: Sousa Meline
Published: November 2023

Um dos problemas com os quais os leitores da Metafísica de Aristóteles se deparam é a dificuldade de delimitação do sujeito da sabedoria. Avicena (séc. X), em seu tratado metafísico As coisas divinas (Ilāhiyyāt), põe-se a investigar cada um dos três candidatos à posição de sujeito desta ciência (a dizer, Deus, as causas e o ser). Devido à amplitude da investigação, a análise que se segue se restringirá à segunda hipótese, a dizer, se, em algum sentido, seria a filosofia primeira uma ciência sobre as causas (uma aitiologia). Deste modo, iniciarei com a exposição do contexto da Ilāh. I que antecede à análise da hipótese das causas. Na sequência, apresentarei a hipótese juntamente com os argumentos para mostrar sua falsidade. Por fim, concluirei com a apresentação da relação entre causalidade e ser tendo em vista a resposta ontológica que será dada ao problema central e os problemas que decorrem desta resposta.

This text discusses what fragility is, how many ways it has been interpreted and how many ways we can interpret it. The first section starts from some etymological and historical-cultural reflections. The second one discusses some paradigms of fragility, and some existential and historical models: from ancient to modern and post-modern times. In the final part, the paper addresses the ambiguities hidden in the term resilience and discusses the so-called theory of the anti-fragile, indicating its possibilities and limits.

Published: November 2023

O presente artigo tem como objetivo validar para aplicação em empresas do setor industrial a escala de mensuração da capacidade estratégica de Resiliência Organizacional desenvolvida por Lee et al. (2013). Para isso, foi conduzida uma pesquisa com 331 trabalhadores de diferentes empresas atuantes no setor inseridas no Estado do Rio Grande do Sul. Como método, optou-se pela validação de construto, que consiste na análise da consistência interna da escala (Alfa de Cronbach) e na verificação de suas propriedades psicométricas (Análise Fatorial Confirmatória). Os índices obtidos ficaram dentro dos parâmetros de confiabilidade propostos pela literatura, demonstrando a validade de construto e aplicabilidade da escala. Diante disso, esse estudo contribui para a gestão de riscos das organizações, disponibilizando uma ferramenta confiável de pesquisa que pode ser utilizada para mensuração da capacidade estratégica de resiliência organizacional. Com projeções de ocorrência de eventos extremos (mudanças climáticas, crises financeiras, desastres naturais, guerras, pandemias, agitação social etc.) indicando que tais perigos inesperados serão mais frequentes e severos, criando altos níveis de incerteza e ameaça aos objetivos de alta prioridade das organizações, a capacidade de resiliência organizacional deve ser considerada uma habilidade inestimável rumo à continuidade do negócio, e a ferramenta validada nesse estudo, pode contribuir com informações relevantes para a redução dos impactos prejudiciais dessas perturbações ambientais.

Published: November 2023

Este artigo busca descrever e analisar a cultura organizacional, o compartilhamento do conhecimento e a maturidade do conhecimento em uma instituição pública de ensino. Trata-se de uma pesquisa descritiva e de campo, com abordagem quantitativa. Os resultados mostram que os servidores estão mais ligados ao profissionalismo cooperativo indicando disposição dos docentes e técnicos na interação com os colegas e trabalham em equipe. Pôde-se perceber que há maior disposição por parte dos servidores em doar seus conhecimentos, embora não tenham a mesma visão dos colegas. Os resultados ainda indicaram que os servidores percebem a qualidade da infraestrutura de TI adotados pela alta administração, entretanto os processos de conhecimento e a liderança em GC estão em um nível quase fraco de maturidade, o que constata uma carência de processos que auxiliam a retenção do conhecimento obtido. Este trabalho mostra a relevância de estudos nacionais que desnudem as percepções de cultura, transferência e maturidade do conhecimento.
Mathematical Modeling of the Processes of Executing Packages of Tasks in Conveyor Systems with Intermediate Buffers of Limited Size
Authors: Krotov Kirill
Published: November 2023

Modern methods of process planning in conveyor systems with buffers of a certain size between processing devices allow optimizing schedules for single tasks or fixed task packages with a limited number of them and a limited number of devices. The use of mathematical models of the processes of performing single tasks (task packages) used by these methods in optimizing the composition of packages and schedules for their execution in systems with an arbitrary number of packages and devices is impossible. At the same time, mathematical models of the processes of executing task packages in conveyor systems in the presence of buffers of limited sizes between devices are the basis for the development of methods for optimizing their (package) compositions and schedules for the implementation of actions with them on the devices of conveyor systems. In this regard, the article develops mathematical models of multi-stage processes of performing an arbitrary number of task packages in conveyor systems in the presence of intermediate buffers of limited sizes for two and three devices, as well as for an arbitrary number of devices. The use of these models makes it possible to determine the time points of the start of the execution of task packages on the devices of conveyor systems, taking into account the limited size of intermediate buffers, as well as the duration of time intervals for the use of these resources and the efficiency of their use over time. An algorithm has also been developed for mathematical modeling of the processes of executing task packages in conveyor systems in the presence of intermediate buffers of limited size, which calculates the time characteristics of these processes based on a given order of implementation of actions with task packages on the devices of conveyor systems. An application has been developed that implements synthesized mathematical models of the processes of executing task packages in conveyor systems with intermediate buffers of limited sizes and an appropriate method for modeling these processes. Versatile testing of the developed application has shown that the obtained mathematical models and the modeling method adequately describe the course of multi-stage processes of task packages in pipeline systems, set using different values of their (processes) parameters.
On the Partial Stability of Nonlinear Discrete-Time Systems with Delay
Authors: Vorotnikov Vladimir
Published: November 2023

A system of nonlinear discrete (finite-difference) of a general form with a bounded delay is considered. Interest in the tasks of qualitative analysis of such systems has increased significantly in recent years. At the same time, the problem of stability with respect to all variables of the zero equilibrium position, which has a great generality, is mainly analyzed in domestic and foreign literature. The main research method is a discrete-functional analogue of the direct Lyapunov method. In this article, it is assumed that the system under consideration admits a “partial” (in some part of the state variables) zero equilibrium position. The problem of stability of a given equilibrium position is posed, and stability is considered not in all, but only in relation to a part of the variables that determine this equilibrium position. Such a problem belongs to the class of problems of partial stability, which are actively studied for systems of various forms of mathematical description. The proposed statement of the problem complements the scope of the indicated studies in relation to the system under consideration. To solve this problem, a discrete version of the Lyapunov– Krasovskii functionals method is used in the space of discrete functions with appropriate specification of the functional requirements. To expand the capabilities of this method, it is proposed to use two types of additional auxiliary (vector, generally speaking) discrete functions in order to: 1) adjustments of the phase space region of the system in which the Lyapunov–Krasovskii functional is constructed; 2) finding the necessary estimates of the functionals and their differences (increment) due to the system under consideration, on the basis of which conclusions about partial stability are made. The expediency of this approach lies in the fact that as a result, the Lyapunov-Krasovskii functional, as well as its difference due to the system under consideration, can be alternating in the domain that is usually considered when analyzing partial stability. Sufficient conditions of partial stability, partial uniform stability, and partial uniform asymptotic stability of the specified type are obtained. The features of the proposed approach are shown on the example of two classes of nonlinear systems of a given structure, for which partial stability is analyzed in parameter space. Attention is drawn to the expediency of using a one-parameter family of functionals.

Published: November 2023

Approximation of the series of the seasonal vegetation index time series is the basis for monitoring agricultural crops, their identification and cropland classification. For cropland of the Khabarovsk Territory in the period from May to October 2021, NDVI and EVI time series were constructed using Sentinel-2A (20 m) multispectral images using a cloud mask. Five functions were used to approximate time series: Gaussian function; double Gaussian; double sine wave; Fourier series; double logistic. Characteristics of extremums for approximated time series for different types of arable land were built and calculated: buckwheat, perennial grasses, soybeans, fallow and ley. It was shown that each type requires a characteristic species. It was found (p<0.05) that Fourier approximation showed the highest accuracy for NDVI and EVI series (average error, respectively, 8.5% and 16.0%). Approximation of the NDVI series using a double sine, double Gaussian and double logistic function resulted in an error increase of 8.9-10.6%. Approximation of EVI series based on double Gaussian and double sine wave causes an increase in average errors up to 18.3-18.5%. The conducted a posteriori analysis using the Tukey criterion showed that for soybean, fallow and ley lands, it is better to use the Fourier series, double Gaussian or double sine wave to approximate vegetation indices, for buckwheat it is advisable to use the Fourier series or double Gaussian. In general, the average approximation error of the NDVI seasonal time series is 1.5-4 times less than the approximation error of the EVI series.

Published: November 2023

Due to its remoteness, little is known about the occurrence and abundance of cetaceans and sea turtles in the pelagic mid-Atlantic Ocean. Data on cetacean and sea turtle occurrence and distribution were collected by dedicated biological observers to address U.S. monitoring and mitigation requirements associated with a vessel-based academic geophysical survey in international waters in the northwestern and mid-Atlantic Ocean from 14 June through 16 July 2018. A total of 6,949 km (503 h) of visual observations occurred while surveying north from Bermuda and ending in Woods Hole, Massachusetts. A total of 928 cetaceans representing at least 14 species and 15 sea turtles representing three species were observed. The most frequently observed cetacean species was the Atlantic white-sided dolphin (Lagenorhynchus acutus) (340 individuals; 37%) followed by the short-beaked common dolphin (Delphinus delphis) (286 individuals; 31%) and pilot whales (Globicephala spp.) (95 individuals; 10%). These sighting data also included an extralimital sighting of a sperm whale (Physeter macrocephalus) calf at 43.44° N latitude and 36.85° W longitude, and extralimital sightings of Atlantic white-sided dolphins below 38° N latitude. Loggerhead sea turtles (Caretta caretta) were seen most frequently (6 individuals). This study addresses a data gap in documented occurrence and lack of occurrence of cetaceans and sea turtles over a large pelagic area in the northwestern Atlantic Ocean during summer.

Published: November 2023

ABSTRACT Objective: To analyze content validity evidence and response processes of a bank of items for measuring vulnerability to physical inactivity in adults. Method: Methodological study, with 13 specialists and 46 representatives of the target population. The Content Validity Index (CVI) and binomial test were calculated; data obtained through validity based on response processes were collected through interviews. Results: Of the 105 constructed items, 16 were excluded (CVI<0.78); 89 items showed agreement <80% in the psychometric criteria, being modified. Of the 101 items that remained (CVI>0.78), 34 were changed and 4 were deleted after evaluating the evidence of response processes. In the end, 97 items remained, with a global CVI of 0.92, organized into two dimensions: Subject (CVI=0.91) and Social (CVI=0.94). Conclusion: The items presented adequate parameters and evidence of validity; and can subsidize the construction of instruments that consider the subject’s and social vulnerability in understanding physical inactivity.

Published: November 2023

ABSTRACT The article lists as a hypothesis that the concept of Developmental State has recently undergone variations and needs to be revisited and updated, but not discarded; on the contrary, it remains extremely important nowadays. In order to test its hypothesis, the article adopted as a technical-methodological procedure a systematic approach of bibliographic sources, intending to conduct a State-of-the-Art Study about the Theory and the concept of the Developmental State. The results obtained were that the concept of Developmental State remains elementary, but it has become more complex, intricate, aggregated and dynamic. The article dares, therefore, to present a new concept of Developmental State.

Published: November 2023

Abstract The increase in the number of Brazilian protected areas has been progressive and, although it is essential for the conservation of biodiversity, it is important to monitor and properly manage these areas, as they present several cases of biological invasions. The Lençóis Maranhenses constitute the peculiar delta of the Americas and are under the consequences of the bioinvasion of tilapias and peacock bass. Collections were carried out in the Lençóis Maranhenses National Park from March/2016 to November/2020, with the aid of gill nets and cast nets. The species were identified with the help of specialized literature and a historical comparison with previous works was carried out. Cytochrome oxidase subunit I was sequenced to confirm identification of non-native species. We recorded the expansion of the occurrence of Oreochromis niloticus, and the first record of the species Oreochromis mossambicus and Cichla monoculus. A total of 31 species belonging to eight orders, eighteen families and twenty-nine genera were identified, indicating a lag in the diversity of species found in relation to previous studies. After 20 years of the first record of invasive fish, there is an expansion of bioinvasion and new cases that indicate a lack of monitoring and containment measures for the species, indicating the fragility of conservation in the area

Abstract Simultaneous analysis studies of several agronomic traits in cultivated plants make it possible to identify phenotypic and genotypic differences due to environmental variations, such as altitude. Therefore, the objective was to evaluate, through multivariate analysis of agronomic, physicochemical and physiological characters, passion fruit hybrids cultivated in different environments. The hybrids used were Gigante Amarelo, Rubi do Cerrado and Sol do Cerrado, cultivated in the southern region of Espírito Santo in four municipalities/environments: Marataízes (41 m), Jerônimo Monteiro (104 m), Alegre (711 m), and Ibitirama (1016 m). The agronomic characters of the plants, the physical-chemical characteristics of the fruits and the physical, biochemical and physiological qualities of the seeds were analyzed. The Singh method was used to determine the most important differentiating characters between hybrids growing in different environments. Based on these characters, a dissimilarity matrix was generated and a principal coordinate analysis was performed. It was observed that the pulp yield was influenced by altitude. The three hybrids showed greater performance in terms of agronomic characters at altitude (41 m) than at altitude (104 m). The Sol do Cerrado hybrid showed high performance in the physical-chemical characteristics of the fruits at altitude (104 m).

Published: November 2023

Abstract Paclitaxel (PTX) is a potent anticancer drug. In the present study, PTX was loaded in poly-3-hydroxybutyrate-co-3-hydroxyvalarate (PHBV) to fabricate the PTX/PHBV (drug-loaded) nanoparticles via the nanoprecipitation method. Blank PHBV nanoparticles were also prepared. The drug-encapsulation efficiency of PTX/PHBV nanoparticles was 45±0.4%. The PTX/PHBV nanoparticles exhibited a pH-sensitive release profile and followed a quasi-Fickian diffusion mechanism. Cytotoxic properties of PHBV and PTX/PHBV nanoparticles were checked against the MCF-7 and Caco-2 cell lines. The PHBV nanoparticle did not inhibit the proliferation of MCF-7 and Caco-2 cell lines, thus depicting their non-toxic and biocompatible nature. On the other hand, the PTX/PHBV nanoparticles demonstrated 1.03-fold higher cytotoxicity and 1.61-fold enhanced apoptosis after treatment with the PTX/PHBV nanoparticles versus free PTX. In summary, the PHBV nanoparticles could be a potential candidate for the delivery of PTX for cancer treatment.

Published: November 2023

Abstract The use of synthetic surfactants reflects the high demand in the hygiene and cleaning sector for products with low-cost and good-effectiveness. These ingredients are the main components of intimate soap formulations. Sapindus saponaria L. is a plant rich in saponins, with the potential to be used as a natural surfactant due to its amphiphilic character and its foam-forming properties. Therefore, this study aimed to develop intimate soap formulations using S. saponaria extract as a natural surfactant and analyze its stability and surfactant characteristics. Preliminary and accelerated stability parameters, rheological characteristics, surface tension, foaming power, foam stability and emulsification potential were evaluated. The formulations were stable at a pH suitable for the intimate region (4.0 to 4.5), the presence of S. saponaria extract provided greater reduction of surface tension, better foaming and foam stability and greater emulsification power, desirable characteristics for an intimate liquid soap. These results demonstrate that the incorporation of S. saponaria extract into liquid soap formulations is an excellent option as a natural surfactant to reduce the use of synthetic anionic surfactants such as SLES.

Abstract A 100-year-old male patient was admitted with a ruptured abdominal aortic aneurysm due to type IA endoleak. Given the proximity of the ruptured site to the superior mesenteric artery (SMA) and renal arteries, a ChEVAR was indicated. Catheterization of the target visceral vessels was a challenging procedural step because of an intensely tortuous thoracic aorta. This hostile aortic anatomy also inhibited exchange for a super stiff guide-wire and selective cannulation with the diagnostic catheter was repeatedly lost when guidewire exchange was attempted. To overcome this issue, a 5 x 40 mm balloon catheter was placed 3cm into the target arteries. The balloon was then inflated below the nominal pressure limit enabling safe exchange for a super stiff guidewire and placement of three 90-cm long 7Fr guiding sheaths. The procedure was thus safely performed with deployment of an aortic extension and the bridging stents.

Resumo Contexto O trauma vascular acomete frequentemente os membros inferiores; entretanto, ainda há dúvidas sobre quais fatores levam a desfechos desfavoráveis. Objetivos Determinar o perfil das vítimas de traumatismo femoropoplíteo, o tratamento utilizado e fatores relacionados a desfechos desfavoráveis. Métodos Estudo retrospectivo, baseado em prontuários de pacientes operados entre 2017 e 2021. Foram analisados: sexo, idade, distância percorrida para atendimento, mecanismo de trauma, presença de choque hipovolêmico, lesões associadas, tratamento, realização de fasciotomia, decisões intraoperatórias inadequadas e índice de severidade de trauma. Necessidade de reintervenção, amputação e óbito foram considerados desfechos desfavoráveis. Foram utilizadas análises univariadas, bivariadas e regressão logística. Resultados Noventa e quatro pacientes foram selecionados, sendo 83% homens, com idade média de 30,8 anos. Lesões arteriais e venosas simultâneas ocorreram em 57,5% dos casos; vasos femorais superficiais foram mais acometidos (61,7%), e mecanismos penetrantes, mais prevalentes (80,9%). Lesões arteriais foram frequentemente tratadas com enxerto venoso (59,6%), e lesões venosas foram submetidas à ligadura (81,4%). Em 15% houve decisões cirúrgicas inadequadas, sendo o uso da safena magna ipsilateral para reconstrução arterial a mais comum. Ocorreram desfechos desfavoráveis em 44,7% dos casos; em 21,3%, foi necessária reintervenção; amputação em 25,5%; e ocorreu óbito em 9,5% dos pacientes. Conclusões As lesões acometeram principalmente homens jovens, vítimas de ferimento por arma de fogo. Vasos femorais superficiais foram os mais lesados, e traumatismos não vasculares concomitantes foram frequentes, principalmente fraturas. Decisões cirúrgicas inadequadas aumentaram em 34 vezes a necessidade de reintervenções. Necessidade de realização de fasciotomia, presença de fratura/luxação, mecanismo contuso de trauma e lesão de artéria poplítea aumentaram o risco de amputação.

ABSTRACT The aims of this study were to search for the presence of bacterial and fungal growth in urine samples from cats with urethral obstruction, to identify the causative infectious agents, and to compare select clinical-laboratory parameters with urine culture results after urethral catheterization. Twenty-eight male cats were enrolled in this prospective study. Urethral catheterization was performed aseptically, and the catheter was maintained for 24-48 hours with a sterile closed collection system. No antibiotics were used during this period. The first urine sample was obtained at the time of presentation, and the second, 24-48 hours after catheter removal, both by cystocentesis. Two cats (7.1%) presented a positive bacterial urine culture on the first sample. The frequency of positive urine cultures in the second sample was 52.4% (11/21 cats). One third of bacterial pathogens were Gram-positive, one third were Gram-negative, and one third were mixed isolates. Fungal cultures were all negative. There was significant association of positive urine culture results with pyuria (P=0.0128). A high frequency of positive urine cultures after urinary catheter removal was observed, despite respecting the standards of care for urethral catheters. Still, these results should be interpreted with caution, since intermittent bladder flushing was performed disconnecting the collecting system, which may have represented a critical point for bacterial contamination. It is emphasized that urine cultures should be considered as follow up in cats with urethral obstruction, after urethral catheter removal.

ABSTRACT The objective of this work was to describe the clinical, pathological, and serological aspects of paratuberculosis in a bullock on dairy and beef farm in the municipality of Inhangapí, state of Pará. The animal was raised extensively and presented progressive weight loss, pale mucous membranes, and chronic diarrhea. A blood sample was collected for serology by the indirect ELISA technique. Due to the unfavorable prognosis, the animal was euthanized and necropsied. At necropsy, there was thickened and wrinkled intestinal mucosa, enlarged mesenteric lymph nodes and liquid intestinal contents with a brown color. Organ fragments were fixed in 10% buffered formaldehyde, embedded in paraffin wax, cut, and stained by hematoxylin and eosin and by Ziehl-Neelsen techniques. Histopathology showed intense granulomatous infiltration with Langhans giant cells in the lamina propria and submucosa of the small intestine, Peyer patches and mesenteric lymph nodes. Ziehl-Neelsen staining revealed many intralesional acid-fast bacilli. Antibody searching against Mycobacterium avium (subsp.) paratuberculosis was positive. The diagnosis of paratuberculosis was based on epidemiological, clinical, pathological, and serological data. This is the first report of clinical paratuberculosis, confirmed by pathology and serology, in a bullock in the state of Pará.

ABSTRACT Fusarium head blight, also known as fusariosis, is caused by a fungus called Fusarium graminearum that produces the mycotoxin deoxynivalenol (DON). This toxin causes problems to human and animal health. Ammonia gas has been shown to be effective in deactivating mycotoxins. The objectives of this study were to evaluate the effectiveness of ammonia gas in the deactivation of DON in wheat grains, the effect of this treatment on its protein composition and the toxicity in rats fed with ammoniated wheat grains. Wheat samples were exposed to ammonia gas at concentrations of 0% (Control), 0.5%, 1% and 1.5%. It was observed that ammonia gas was effective in deactivating DON at concentrations of 1% and 1.5%. There was no difference in crude protein observed in the bromatological analysis of treated wheat grains in relation to the control. Regarding the toxicity of wheat grains treated with ammonia in the feeding of Wistar rats (Rattus norvegicus), no histopathological alterations were observed in the liver, kidneys, intestine and in the hematological profile. The results of this study demonstrated that the treatment of wheat with ammonia gas can contribute to the deactivation of DON without compromising its protein composition and animal health.

Abstract Objectives: to investigate digital dating violence among adolescents. Methods: qualitative research, applying the ecological engagement methodology, carried out in a non-governmental organization. The final sample consisted of eight male and female adolescents, aged between 16 and 19 years old. Data were analysed according to Content Analysis technique, with triangulation of instruments and technique: biosociodemographic questionnaire; field notes; semi-structured interview; questionnaire “Knowing Dating Relationships”. Results: digital violence was frequent and naturalized in dating; despite mutual violence, bidirectionality in dating violence did not mean gender symmetry; the pandemic was linked to the daily increase in Internet use via mobile phones, but it did not increase dating violence. Impulsivity was used in attempts to resolve conflicts in dating, associated not only with adolescence, but also with the increasing digitization and acceleration of relationships within our society. Adolescents were direct and/or indirect victims of violence in their main development microsystems (family, school and neighborhood), simultaneously exposed to different types of violence, since childhood. Conclusions: the digital microsystem can be seen as another context for the perpetration and victimization of violence. Preventive actions should consider the various expressions of violence (physical, psychological, sexual and digital) and their repercussions for physical and mental health.

ABSTRACT Measurements of biodiversity can be used to assess the scale of anthropogenic impact and predict species loss. A great number of diversity measures exist involving species richness and relative abundance that differ in how they are calculated. The choice of the adequate biodiversity measure to compare biological communities poses a challenge. The aim of this study was to evaluate the ability of 26 diversity measures to differentiate land cover types in the eastern Brazilian Amazon. Diversity was inventoried and quantified in three vertical strata in six locally dominant land cover types: primary and secondary forests, agroforestry systems, oil palm plantations, annual croplands and pastures. No diversity measure was able to differentiate all land cover types in every stratum. Fisher’s alpha was able to differentiate cover types in the middle and upper strata, while Smith-Wilson and Jentsch’s mixture quotient were able to differentiate in the lower and upper strata, and heterogeneity indices only differentiated in the upper stratum. The distinction and ranking of plant diversity among land covers depended on the diversity measure chosen. The number and types of land cover and vertical strata were a key factor in the ability of the diversity measure to differentiate among them.
