Introduction: Federal university hospitals are characterized by the complexity of their organizational structure, which encompasses multiple interdependent processes focused on care, teaching, and research. In the context of clinical research, this complexity is accentuated due to the multiplicity of responsibilities and stakeholders, institutional interfaces, and operational flows involved in conducting studies. When such processes are not properly defined and articulated, they can lead to rework, inefficiency, and compromise scientific and administrative results. Objective: To analyse the institutional processes that comprise the pre-study phase of sponsor initiated clinical research at a university hospital. Method: This is an action research study based on the need for collective knowledge construction. Professionals from different areas who worked on clinical research protocols at the university hospital participated in the study. The theoretical framework was supported by a scoping review on clinical research management, which guided the development of process mappings and a guidance manual for the pre-study activities. The development and validation of these products took place through six seminars, recorded in audio and video, transcribed, and submitted to Bardin’s categorial and lexical analysis using IRaMuTeQ software to identify challenges in conducting research. Results: The technical products – process mapping and manual – represent practical contributions, as they offer a structured basis for organization, clarity of responsibilities, optimization of flows, and ethical and legal compliance. Academic productions such as the scope review and articles, one focused on analyzing the process mapping development and the other on lexical analysis exploring the challenges, can inspire other institutions that encounter similar difficulties in structuring and managing clinical research in public university environments.

Emerging metal contaminants can pose risks to human and environmental health, but their effects have not yet been widely studied. This work aimed to evaluate the effects of zirconium (Zr) on plant organisms, using bioassays with Lactuca sativa L., Allium cepa L. and Phaseolus vulgaris L. Solutions containing zirconium dioxide were prepared in different concentrations: 200 μg (C1), 100 μg (C2), 50 μg (C3), 25 μg (C4) and 12.5 μg (C5), diluted in 0.5% dimethylsulfoxide (DMSO). Distilled water was used as a negative control (NC) and the DMSO solution as a control for the dilution vehicle. L. sativa seedlings germinated in the test solutions were analyzed for germination and initial growth. Roots of A. cepa, also germinated in the test solutions, were used to evaluate the cytogenotoxic potential by analyzing the cell cycle and inducing DNA damage by observing chromosomal and nuclear alterations. In P. vulgaris, leaf morphology, pigment and total nitrogen indices, root and shoot biomass and length were analyzed. The data was subjected to the Shapiro-Wilk normality test and then ANOVA with Tukey's test or the Kruskal-Wallis test (P < 0.05). None of the concentrations tested affected the development of L. sativa. Zr did not induce chromosomal or nuclear alterations in meristematic cells, but in F1 cells, the C1 solution showed damaging potential. In P. vulgaris, there was a dose-dependent increase in the anthocyanin index. Only plants treated with C1 showed a reduction in the length of the aerial part. Although the fresh mass did not differ between the groups, the dry mass of the roots and aerial part was reduced in C1, and the roots were also affected in C2. Thus, Zr showed the potential to cause toxic effects in plant organisms, impacting growth and inducing damage at high concentrations.

This paper focuses on collaborative work in special education in the municipality of Vila Velha - Espírito Santo: A case study. Our overall objective was to understand the role of the Special Education Collaborating Teacher in the regular classroom, revealing their functions, actions, and daily practices. We adopted a qualitative methodological approach, as it favors in-depth analysis of human phenomena, subjective perceptions, and social relationships. Specifically, a case study was used as the methodological design, aligned with the nature of the research and allowing for a deeper understanding of the particularity and complexity of collaborative work in a specific context. The theoretical framework is based on Vygotsky's historical-cultural perspective, which understands human development and learning as socially mediated processes. The literature points to the existence of conflicts inherent in the inclusion of students with disabilities in regular classrooms, which can negatively impact the process. Therefore, the central question guiding this research is: What do professionals working in collaborative Special Education in Vila Velha - Espírito Santo, have to say about their roles, actions, and daily practices? As a result, the research sought to explore the concepts surrounding collaborative work in Special Education and analyze how it manifests itself in the municipal schools of Vila Velha - Espírito Santo. Collaborative teaching is essential to promoting inclusion, especially when recognizing the need for adaptations and modifications to regular classroom activities, the environment where students spend most of their time. The pedagogical practices of collaborating teachers are conceived as knowledge mediating actions, aiming to make learning more accessible. This includes joint planning, the application of adapted teaching methods, the creation of differentiated activities, ongoing student support, and the assessment of the teaching and learning processes of students with special education indications.

Accounting has undergone transformations with the adoption of CPC 47 – Revenue from Contracts with Customers, which standardized revenue recognition across all economic sectors, replacing previous fragmented regulations (Dias & Costa, 2024). This research investigates the effects of the adoption of CPC 47 on working capital management and the economic performance of Brazilian companies listed on [B]³, analyzing periods before and after the mandatory implementation of the standard. Quantitative analysis techniques were employed, including robust linear regressions, quantile regressions, and non-parametric tests, to assess statistical differences between periods and sectors with higher and lower exposure to the standard. The sample comprises 1,610 observations of companies listed on [B]³ between 2010 and 2023, excluding financial institutions. The variables of interest include the Cash Conversion Cycle (CCC) and Return on Assets (ROA), along with control variables such as company size, COVID, financial leverage, and corporate life cycle stage. The OLS linear regression results indicate that the adoption of CPC 47 did not significantly impact working capital management and economic performance in a generalized manner. However, sector-based analysis, through additional hypotheses, revealed that companies more exposed to the standard, such as those in Construction and Industrial Goods, experienced greater changes in working capital management, while Industrial Goods, Healthcare, and Technology sectors showed negative impacts on economic performance, confirming sectoral variations. The quantile regression, used as a robustness test, revealed that the impacts of CPC 47 were not homogeneous across the distribution of financial variables. Companies with longer cash conversion cycles adjusted their strategies to reduce CCC after the adoption of the standard, while companies at the extremes of the ROA distribution (less profitable and highly profitable firms) were the most negatively affected. The findings contribute to the literature by demonstrating that accounting standardization can have differentiated effects across economic sectors. From a practical perspective, the study provides valuable insights for regulators, managers, and investors regarding the financial impacts of adopting new accounting standards and their implications for the predictability of corporate results.

The pulp and paper industry, during its process, generates valuable products that have found applications in various industrial areas, with emphasis on cellulose microfibrils (MFC), cellulose nanocrystals (CNC), and lignin. Cellulose microfibrils are fibers with nanometric dimensions, while cellulose nanocrystals are crystalline particles, both obtained from the cellulose molecule. Lignin, on the other hand, is a macromolecule associated with cellulose and hemicelluloses in lignocellulosic compounds. Both materials have been extensively explored in materials engineering due to their mechanical, physical, chemical, and biological properties. The use of these products is not limited to the pulp and paper industry but extends to sectors such as the textile and automotive industries, packaging production, among others. The innovative application of these materials has led to remarkable advancements in various fields, from the development of lighter and more sustainable materials to the creation of innovative solutions in different segments. Investment in research and development in this field is a way to find increasingly innovative pathways for the use of these co-products, providing both economic and environmental benefits. In this context, this work produced epoxy matrix composites with 20% epoxidized soybean oil (ESO) reinforced with varied compositions of CNC and lignin. The produced composites were characterized through mechanical tests of tensile and flexural strength, thermal analysis (TG/DSC), X-ray diffraction (XRD), scanning electron microscopy, and tests for water absorption behavior, accelerated UV-C degradation, and FTIR. It is expected that these materials will influence various properties of the composites, but, above all, that the resulting materials will present characteristics that enable new applications.
