The main transmission route of bovine coronavirus (BCoV) is direct contact with secretions and feces, and potentially also via contaminated surfaces. Following PRISMA guidelines, a systematic review was conducted to evaluate the presence of BCoV on environmental surfaces. A literature search, conducted between March and April 2023, utilized databases including Web of Science, PubMed, Scopus, Science Direct, and Springer. The review adhered to the PEO structure: Population - environmental surfaces; Exposure - contact with BCoV; Outcome - identification of presence or infectivity. Primary data were recorded using an extraction form organizing methods for detecting BCoV presence, assessing BCoV infectivity, types of surfaces evaluated, and study type. Search terms “Bovine coronavirus” and “BCoV” yielded 2703 articles. After removing 964 duplicates and excluding 1546 articles not mentioning BCoV in titles, 193 studies underwent abstract reading. Following exclusion criteria not addressing BCoV presence in the environment, three articles were selected for comprehensive review. These articles identified BCoV presence on various types of surfaces, with detection possible up to 81 hours after contamination, depending on surface type. Despite limited studies on BCoV presence on surfaces, findings suggested potential transmission via contaminated surfaces due to the virus’s ability to remain infectious for up to 24 hours on fomites. This review underscores the need for further research on BCoV persistence in farm environments, an area currently lacking focused studies.

The use of by-products from the wood industry as an alternative to obtaining cellulose, using an eco-friendly process is essential for the sustainable production of high value-added bioproducts. In this research, the cellulose/chondroitin sulfate membranes were obtained using saw dust as the cellulose source. Initially, cellulose was extracted using peracetic acid (PA) in one (Cel1) and two cycles (Cel2) and mercerized with NaOH. Analysis of the products obtained by X-ray diffraction (WAXD), Fourier transform infrared spectroscopy (FTIR) and Ultraviolet–Visible Diffuse Reflectance Spectroscopy (UV–Vis DRS) confirmed that the extracted cellulose was type II and that the reduction of lignin (from 36 to 3.5%) did not depend on the number of bleaching cycles. Membranes with and without the addition of borax were obtained by dissolving cellulose in NaOH/urea/H2O (7/12/81% m/m), mixed with chondroitin sulfate (SC) in proportions 100/0; 90/10; 80/20 and 70/30 (% m/m). The effect of SC contents and the presence of borax on the properties of membranes produced was investigated. The results showed that the swelling ratio, equilibrium water content and kinetic mechanism of water absorption were influenced by the presence of borax and the amount of chondroitin sulfate. The results demonstrated that the properties of Cel/SC membranes could be modulated by the composition and had potential for application in the biomedical area. Graphical abstract

Resumo No Brasil, construções em madeira do tipo light woodframe possuem envelopamento estrutural do painel dependente do uso de chapas de OSB (Oriented Strand Board), o que implica em uma dificuldade em seu acesso por parte da população. Para ampliar a aplicação do sistema, uma possibilidade consiste em um projeto não atrelado aos monopólios de componentes construtivos. Uma possibilidade é a substituição da camada de envelopamento estrutural dos painéis por tábuas de madeira serrada convencional. Como objetivo esta pesquisa analisa a viabilidade de utilização e o comportamento de painéis de madeira serrada com envelopamento em tábuas de pinus quando solicitados a esforços horizontais, utilizando modelo numérico de simulações em software. O trabalho estuda cinco diferentes tipologias de painéis: um modelo digital de calibração baseado em experimento ensaiado em laboratório; quatro modelos de diferentes configurações, comparando entre si o desempenho estrutural de cada um com dados publicados na literatura. A modelagem digital utilizou dados experimentais já obtidos em trabalhos anteriores. Dos cinco tipos estudados quanto à tensão-deformação, apenas o Modelo 05 não se mostrou viável pela alta concentração de tensão observada nos conectores. Os demais modelos se mostraram adequados aos critérios preconizados por normas e documentos técnicos referenciados.

This paper aimed to analyze the effectiveness of the CCWorldWeatherGen tool, focusing on climate change in São Paulo, São Paulo State, Brazil. For this, dry-bulb temperature, relative humidity, global solar radiation, and wind speed data from the test reference year weather file (1954) and the CCWorldWeatherGen file for the 2020 period (representing the 2011-2040 period) were compared with observational data collected between 2011 and 2023 by the Meteorological Station of the Institute of Astronomy, Geophysics, and Atmospheric Sciences of the University of São Paulo. The accuracy of variables predicted using weather files was evaluated using five statistical measures of error. Annual relative root mean square error (RRMSE) values for dry-bulb temperature, relative humidity, global solar radiation, and wind speed in the morphed weather file were 17.04% (good), 17.95% (good), 31.57% (poor), and 224.44% (poor), respectively. It is concluded that CCWorldWeatherGen is suitable for generating future weather files with complete information, mainly for its practicality. However, this approach requires caution, as sequences depend on the consistency of the weather file used as a basis.

Resumo O Serviço de Atendimento Móvel de Urgência (SAMU) é o componente móvel pré-hospitalar da Rede de Atenção às Urgências. Funciona como um observatório privilegiado da rede que possibilita a articulação e integração com os diversos serviços de saúde. Este estudo objetiva avaliar a governança de financiamento de um SAMU Regional. Trata-se de um estudo avaliativo, desenvolvido de junho de 2017 a agosto de 2018, por meio de análise documental e de entrevistas com sete informantes-chave do SAMU da macrorregião norte do Estado do Paraná. Os resultados apontam que o aporte financeiro foi efetuado de acordo com normatizações, porém insuficientes para a manutenção do serviço, tendo os municípios arcado com mais de 50% do total de gastos no período do estudo. Foi possível inferir que a governança de financiamento deste SAMU é incipiente, pois as informações sobre o financiamento foram díspares, pouco divulgadas e pouco apropriadas pelos atores envolvidos em seu processo de governança. Conclui-se que a deficiente governança de financiamento contribui para ampliar a dificuldade do SAMU no cumprimento da função de ordenar e articular a integração dos componentes da Rede de Urgência e Emergência.

The consumption of sugar-sweetened beverages (SSB) is increasing worldwide, especially in developing countries. Beyond the potential health outcomes of SSB taxation, its economic effects must be examined. This article aims to analyze the wide-economy impacts of SSB tax in Brazil in the short- and long-term. We used a national dynamic computable general equilibrium model calibrated for the Brazilian economy, using data from the 2015 input–output matrix released by the Brazilian Institute of Geography and Statistics. The model evaluates the effects on macroeconomic indicators of production, employment, household consumption, prices and tax revenue from 2023 to 2032. We analyzed four scenarios, considering different levels and schemes of taxation. In the short term, we observe a decrease in SSB consumption and negative macroeconomic impacts when government spending remains unchanged. However, redirecting the tax revenue towards public health expenditure mitigates these negative effects while maintaining similar outcomes for the SSB industry.

This article studies Portuguese libraries that have won the “Libraries: Development and the 2030 Agenda” award promoted since 2018 by the Portuguese Association of Librarians, Archivists, Information and Documentation Professionals together with the General Directorate of Books, Archives and Libraries. The aim is to identify the common characteristics of the libraries that have won the award so that these success stories can help other libraries with guidance on what characteristics they should develop in their teams in order to develop projects and actions that contribute to a more sustainable world. The method used is grounded theory with human analysis and Iramuteq software. Six common characteristics were found among the libraries: partnerships, teamwork, a focus on the community, projects linked to the territory, support and alignment with senior management regarding the SDGs, and funding. These characteristics together can lead to successful projects in the context of the 2030 Agenda and promote innovative services. It is also desirable that the projects developed are constantly monitored and evaluated. We conclude that libraries that want to develop projects for the 2030 Agenda should invest in these characteristics.

Objectives Evaluate if there is a significant difference in isolated reconstruction of the ACL in patients with or without pre-operative associated injury of the ALL. Methods Transversal retrospective study by patient’s files analysis and LYNSHOLM and IKDC questionaries to patients with isolated reconstruction of the ACL. Results The 52 patients were separated in 2 groups: 19 with associated ALL injury and 33 without associated injury. None of the patients with associated ALL injury suffered new ACL tear, but 21,1% had injured other structures, while 6,1% of patients without associated ALL injury suffered new ACL tear and 18,2% injured another structure (p=0,544). The return to activities at the same preoperative level was observed in 60% with associated ALL injury and 72% without associated injury (p=0,309). The LYSHOLM score demonstrated a median of 81,1 points with associated ALL injury and 90,1 without associated injury, and the IKDC, 70,3 points with associated injury and 76,7% without associated injury (p=0,112). Conclusion No significant statistic difference was observed for graft injury or new lesions in other structures, satisfaction with the injured knee or subjective IKDC score. Return to activities was similar in both groups with or without associated ALL injury and the LYSHOLM subjective score demonstrated better results with significant statistical difference in the group without LAL associated injury.

Objectives To compare bleeding and surgical time in patients undergoing Total Knee Arthroplasty (TKA) with robotic assistance with and without the use of a tourniquet. Methods Retrospective study with analysis of medical records. Patients were divided into two groups: one group in which robotic-assisted TKA was performed using a tourniquet and the other without. Hemoglobin change and hematocrit at 24 hours after surgery, the volume of bleeding, number of transfusions and surgical time were compared. Results 108 patients were included. The group using a tourniquet totaled 59 patients and the group without a tourniquet 49 patients. There was no difference between the mean hemoglobin and hematocrit values between the groups, preoperatively (p = 0.287 and p = 0.508) and 24 hours (p = 0.252) after surgery. There was also no difference between the volume of bleeding in each group (p = 0.265). Surgical time was not different between groups (p = 0.179). There was no need for transfusions in any patient. Conclusion TKA surgeries with robotic assistance performed with and without the use of a tourniquet showed no significant difference in Hb change and Ht levels 24 hours after surgery, estimated bleeding volume, transfusions and surgical time.

This work describes the development of a novel biosensor obtained by immobilizing laccase from Pleurotus ostreatus Florida onto a glassy carbon electrode platform modified with zinc oxide quantum dots. For enzyme immobilization, the exopolysaccharide botryosphaeran from Botryosphaeria rhodina MAMB-05 was used. Although both biomaterials are from different fungal sources, laccase immobilization was guaranteed, which was demonstrated by the excellent stability of the fabricated biosensor device for the voltammetric determination of 2,6-dimethoxyphenol (2,6-DMP). Under the optimal experimental conditions, the cathodic current from the square-wave voltammograms presented a linear dependence on the 2,6-DMP concentration within the range of 10–400 nmol L⁻¹, with a limit of detection of 9 nmol L⁻¹. This bioanalytical device exhibited excellent repeatability and long-term storage stability.

Athletes in bodybuilding can pose favouring one side or the other of the body while being evaluated in the contests. While previous research assessed lateral bias of posing in a variety of situations, no investigation has been conducted in bodybuilding. We analyzed the lateral posing bias of the Top 15 athletes for the mandatory poses in Classic Physique Mr. Olympias (2016-2023). Results revealed a general bias to the right in all poses, as either moderately or strongly right-lateralized poses were most frequent. Furthermore, "Front Double Biceps" pose was the most symmetrical, while "Your Favorite Classic Pose" was the most asymmetrical one-apart from the always lateralized "Side Chest". Interestingly, lower-placed athletes (Top 15) posed significantly more often to the right in "Side Chest", as compared to the Top 5 and Top 10 competitors. These findings contrast the left bias shown in portraiture and photography literature, likely as a consequence of motor constraints and coordination for athletes to pose to the right, along with the level of emotional expressiveness a bodybuilder may wish to reveal on stage. Our data expand previous results of posing asymmetry to the sport of bodybuilding in this pioneering research into the lateral bias of posing.

This qualitative meta-synthesis was conducted with the aim to understand fathers’ experiences and involvement when their child has a chronic condition within family context. Family nurse researchers from five countries identified 19 studies through a systematic search. Inclusion criteria were: (a) fathers as primary informant; (b) children (<19 years) with a chronic condition; (c) written in English, Spanish, French, or Portuguese. Data were synthesized using thematic analysis. Four themes reflected fathers’ journey: “Juggling multiple roles” included protector, provider, and supporter; “Managing control” included relinquishing and regaining control; “Creating a new normal” addressed recovery; “Maintaining wellbeing” reflected multiple emotional responses and support found through partners, family, spirituality, and health care communities. Fathers desire to be involved in caring for their child with a chronic condition, yet involvement and experience are continually evolving due to various family needs. Health care providers should consider unconscious assumptions regarding fathers’ role in child care and encourage fathers’ involvement to facilitate family wellbeing.

Resumo Neste artigo temos como objetivo evidenciar os conhecimentos dos alunos de uma turma do 1º ano do Ensino Fundamental em uma atividade de modelagem, sob uma interpretação semiótica do raciocínio diagramático. Entendemos que a modelagem é uma alternativa pedagógica em que, a partir de uma situação problemática da realidade, procedimentos matemáticos são utilizados para se chegar a uma solução para o que se está investigando. O conhecimento é respaldado na semiótica peirceana, mais especificamente, na mobilização do raciocínio diagramático, viabilizado na construção, na experimentação e na observação de diagramas semióticos produzidos pelos alunos. A análise qualitativa subsidiada no processo de triangulação levou em consideração os 25 alunos do 1º ano de uma escola municipal do interior do Paraná como sujeitos, os diagramas produzidos no desenvolvimento da atividade de modelagem como objeto e o fenômeno consiste na mobilização do raciocínio diagramático que emergiu seja pela necessidade dos alunos ou por requerimento da professora. Os dados foram obtidos por meio de gravações em áudio e vídeo, e por meio dos registros produzidos de forma individual ou coletiva. Os resultados permitiram evidenciar que a mobilização do raciocínio diagramático foi efetivada nos diagramas produzidos de forma conjunta entre alunos e professora, principalmente para avançar na geração de representações matemáticas mais sofisticadas como tabela e gráfico, em que houve a construção de novos conhecimentos. Além disso, a interação entre os colegas e a comunicação com toda a turma a partir de uma temática próxima aos alunos promoveu o interesse no desenvolvimento da atividade.

Orbital cellulitis happens when the region behind the orbital septum is affected. It consists an urgency because of its potential risks of complications, such as vision loss, cavernous sinus thrombosis, or Lemierre Syndrome. This article reports a case of a subperiosteal and orbital cellulitis, which had a periapical lesion in the left first molar as it´s focus. Because of the urgency of those cases, the surgeon needs to make an early diagnosis and prompt approach.

The results presented in this article are derived from doctoral research that addressed the theme of paradigm changes in teaching, in response to the transformations in science, education, communication, and information in 21st-century society, which have influenced the pedagogical dimension of teaching, pointing out the need to develop studies on the concepts of constructs and knowledge present in the practices of faculty members in undergraduate teaching programs. Based on the complex thinking theory, the research problem sought to answer: What constructs and knowledge can be pointed out as subsidies for the continuing pedagogical training of university professors, in order to embrace the view of complexity in teaching? The general objective was to conceptualize the constructs and teaching knowledge that meet the vision of the complexity paradigm in teaching in undergraduate teaching courses. The investigation is qualitative, involving bibliographic research, exploratory and descriptive in nature. The study has shown that constructs can be considered both a mentally produced construction and a principle, when established in scientific research, to develop an operational set of measures that will make sense to subjective judgment looking at data collection and moving on to analysis of events, situations or characteristics related to social life. Furthermore, as a result of the investigation, it was possible to identify different dimensions indicated by reference authors on the concept of knowledge, namely: transdisciplinary knowledge, knowledge of educational practices and teaching knowledge.
