Ação dos subprodutos do nitroprussiato de sódio na germinação de sementes de alface sob estresse hídrico e térmico, em um cenário simulado de crise climática
(Universidade Federal do Espírito Santo, 2025-12-03) Bonfá, Yasmim Smarsaro; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; https://orcid.org; http://lattes.cnpq.br/; 5º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
Abiotic stresses generate significant monetary losses due to the imposition of limiting conditions on agricultural production. Among these, climate change can cause not only water stress but also thermal stress, impacting seed germination in such a way as to compromise the full development of the crop, its ability to maintain yield, and consequently the food security of human populations. Sodium nitroprusside (SNP), an inorganic complex, releases cyanide (CN) and nitric oxide (NO) as byproducts of its spontaneous decomposition; the latter is commonly used in germination studies to mitigate the effects of abiotic stress. However, the substance responsible for the beneficial effects attributed to SNP remains unclear. This is particularly important when different products are released by the same compound. Considering the release of byproducts derived from SNP, this study sought to evaluate the role of these byproducts in promoting the benefits of exposing lettuce seeds under water and heat stress to the exogenous administration of SNP and the NO scavenger, PTIO (2-phenyl 4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide). This allowed for a focused elucidation of the contribution of each molecule to the germination results obtained in the presence and absence of NO. A total of 12 treatments were tested: Water, PEG, SNP, SNP+PEG, SNP+PTIO, SNP+PTIO+PEG at temperatures of 20°C and 30°C. The following attributes were evaluated: germination percentage (%G), germination speed index (GSI), fresh mass (FM) and dry mass (DM), root length (R), shoot length (SL), catalase (CAT) and peroxidase (POX) enzyme activity, total protein content, and malondialdehyde (MDA) level. It was found that under water deficit, nitric oxide was essential in overcoming the stress, while under heat stress, it loses its role as a promoter of benefits to cyanide. NO continues to contribute to the system, but apparently its role becomes solely in promoting germination; in contrast, it is cyanide that allows the plant to continue its development. In the simulated climate crisis scenario where water and thermal stress act simultaneously, the action pattern resembles the results found for thermal stress, showing that the water deficit can be overcome by nitric oxide from the SNP. However, whenever there is an increase in temperature, it is cyanide that sustains the overcoming of the difficulties presented by the stresses promoted in this work, regardless of whether it is being influenced by high temperatures or by the synergy of water and thermal stresses
Ana y Siervo siguen sin tierra: el realismo estético como aproximación al conflicto de la posesión de la tierra en los estudios literarios latinoamericanos
(Universidade Federal do Espírito Santo, 2022-02-22) Villa Ramírez, Oscar Jhony; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador2; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador3; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador4; ID do co-orientador4; Lattes do co-orientador4; Soares, Luís Eustáquio; https://orcid.org/; http://lattes.cnpq.br/; Orientador2; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; Amaral, Sérgio da Fonseca; https://orcid.org/; http://lattes.cnpq.br/; Roux, Guillaume Bruno; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; http://lattes.cnpq.br/; 5º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 6º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 7º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
Durante el año 2021, y solo hasta el mes de septiembre, en Colombia se han contado más de 57.000 desplazados de forma violenta desde sus territorios1 . Este fenómeno se ha venido presentando desde mitad del siglo XX, sin embargo, a pesar del reciente acuerdo de paz entre las FARC-EP2 y el Gobierno del Presidente Juan Manuel Santos, el fenómeno se ha intensificado. Esto nos lleva a pensar en los motivos por los cuales el conflicto ha durado más de 50 años, y la respuesta podría encontrarse en expresiones literarias como Siervo Sin Tierra (1950), del autor colombiano Eduardo Caballero Calderón. Con el objetivo de entender la naturaleza, el surgimiento y la duración de este conflicto, encontramos una obra brasilera llamada Ana Sem Terra (1990) del autor Alcy Cheuiche. En ella, también se relata un conflicto violento que termina trágicamente, y cuyos orígenes pueden tener cierta relación con el conflicto colombiano a pesar de sus particularidades. Para entenderlo, haremos un análisis de las dos obras en torno al Realismo Estético. Adicionalmente, estaremos apoyándonos en M. Heidegger y R. Espósito para entender la relación de la tierra con quien la posee y la función de la misma como cosa, razón por la cual se torna en motivo de disputa. Como resultado, la relación entre ambas obras puede ser el punto de partida para abordajes integradores de la realidad latinoamericana en torno a sus conflictos sociales explicando su duración, origen y naturaleza.
Aplicação integrada de técnicas cromatográficas, espectroscópicas e quimiométricas na caracterização de chocolates artesanais
(Universidade Federal do Espírito Santo, 2025-12-18) Altissimo, Joseline; Co-orientador1; https://orcid.org/; https://buscatextual.cnpq.br; Orientador1; https://orcid.org/; https://buscatextual.cnpq.br; https://orcid.org/; https://buscatextual.cnpq.br; 1º membro da banca; https://orcid.org/; https://buscatextual.cnpq.br; 2º membro da banca; https://orcid.org/; https://buscatextual.cnpq.br; 3º membro da banca; https://orcid.org/; https://buscatextual.cnpq.br; 4º membro da banca; https://orcid.org/; https://buscatextual.cnpq.br
The chemical characterization of artisanal chocolates has proven essential to ensuring quality, authenticity, and understanding sensory attributes related to cocoa content. In this work, different analytical approaches were employed to examine organic and inorganic constituents of chocolates produced in Brazil, with cocoa contents ranging from 36 % to 100 %. The chromatographic stage comprised the analysis of 45 samples, of which 17 representative ones were evaluated by HS SPME/GC-MS for the identification of volatile compounds. In total, 72 compounds were identified, including acids, esters, pyrazines, and aldehydes, associated with descriptors such as roasted, nutty, floral, and fruity. Methylxanthines were quantified by HPLC-DAD after the optimization of a US-LLE procedure, which resulted in recoveries of 91,7 % ± 11,3 % for theobromine and 94,7 % ± 2,7 % for caffeine. The obtained concentrations, ranging from 1.158 to 21.033 g kg-1 for theobromine and from 0.058 to 1.998 g kg-1 for caffeine, exhibited a positive correlation with the declared cocoa content. Principal component analysis revealed separation between low- and high-cocoa samples, with theobromine being the variable with the highest discriminant weight. These results reinforced the potential of methylxanthines as useful organic markers for classification and authenticity verification of artisanal chocolates. The spectroscopic investigation involved the application of Laser-Induced Breakdown Spectroscopy (LIBS) to 45 samples. Instrumental conditions were optimized using a 24 factorial design, considering spot diameter, laser energy, delay time, and the emission lines of C, Ca, Mg, and K. The function of desirability enabled the identification of variables with the greatest influence on analytical performance. Multiple Linear Regression (MLR) modeling provided strong correlation between predicted and declared cocoa content, with RMSEC of 4.5 % w/w and RMSEP of 4.0 % w/w. Validation samples showed trueness values between 90 % and 110 %, meeting the established criteria. Principal component analysis showed clear distinction between conventional chocolates (30–65 % cocoa) and higher-content chocolates (70–100 % cocoa), highlighting the contribution of elemental markers such as Ca, Mg, and K. Convergence between chromatographic and spectroscopic methods became evident when comparing monitored organic compounds and elements. Samples with higher concentrations of theobromine and caffeine also exhibited greater Mg and K intensity in LIBS, elements naturally associated with the solid fraction of cocoa. This alignment between organic and inorganic profiles highlighted the direct relationship between chemical composition and cocoa content, reinforcing the integrated use of these techniques for authentication and quality control purposes. The results demonstrate that the combined application of GC-MS, HPLC-DAD, and LIBS, together with chemometric tools, offers an efficient approach to examining the composition of artisanal chocolates, contributing to traceability practices, authenticity verification, and quality enhancement in the sector
Aproveitamento agrícola do biossólido gerado na estação de tratamento de esgoto de Jerônimo Monteiro - ES na laranjeira
(Universidade Federal do Espírito Santo, 2024-11-26) Viçosi, Karen Andreon; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador2; https://orcid.org/; http://lattes.cnpq.br/; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
Sewage sludge, known as biosolids after treatment, is a residue from sewage treatment that can be used in agriculture due to the presence of nutrients and organic matter. Its use in agroecosystems is justified to improve soil properties, increase microbial diversity and promote the circulation of nutrients, being an effective way to increase food production. Although the use of biosolids in agricultural production systems is a great option for reusing this material, this practice still needs to be controlled to be able to provide some risks, such as the presence of heavy metals, pathogens, organic compounds and toxins in excess, which can cause losses in agricultural practice. Another possibility for using biosolids is as a substrate for seedling production. It is capable of increasing the growth and improving the nutrition of seedlings, facilitating the lifespan and the cost of acquiring substrates. However, the physical attributes of biosolids may not be specific to all species, requiring tests to indicate an ideal proportion of biosolids in relation to the substrate. One of the treatments that sewage sludge can undergo is liming, and it is essential to understand the dynamics of soil pH with biosolids fertilization. Unlimed sewage sludge reduces soil pH after 21 days. However, in general, the application of 80 t ha-1 reduces pH by 4.8%, 9.9% and 9.6% for sandy, medium and clayey soils, respectively. Limed sewage sludge presents high soil reactivity after seven days, with a reduction in the occurrence of alkalinization over time. In general, for sandy soil, the pH value was around 7.6, while for medium and clayey soils the pH value was 7.4 at the dose of 80 t ha-1. Sandy textured soils with lower moderate capacity, selected from smaller doses of limed sewage sludge to reach pH 7. Based on these studies, the prediction of biosolids in seedling production and orange tree planning was then tested. Citrus farming is economically important in national agriculture, and also in the southern region of Espírito Santo. Biosolids have the potential to be used in the composition of substrate for the production of citrus rootstocks, replacing the commercial substrate. The use of biosolids in the proportion of up to 60% for Rangpur lime seedlings and up to 45% for ‘San Diego’ citrandarin seedlings promoted better responses in relation to initial growth and plant quality. In the field, biosolids can also be used for initial fertilization of the crop. The application of biosolids at doses of 100%, 115% and 150% of the N recommendation for the crop improved the chemical attributes of the soil, such as P, Ca, SB, CTC, effectiveness and base saturation. The levels of calcium, SB, t, V increased until 9 months, while organic matter increased until 11.7 months. In general, biosolids did not promote an increase in the content of micronutrients (Fe, Cu, Zn, Mn and B) in relation to mineral fertilization
Bebê como método : psicanálise, neoliberalismo e produção de subjetividade
(Universidade Federal do Espírito Santo, 2026-02-09) Rosi, Fernanda Stange; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador2; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador3; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador4; ID do co-orientador4; Lattes do co-orientador4; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; Orientador2; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; http://lattes.cnpq.br/; 5º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 6º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 7º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
This thesis adopts “Baby as Method,” inspired by Child as Method by Erica Burman (2025), to read and interrogate the inscription of psychoanalysis within the practices of subjectivation in modernity. The research is organized around four figurations that serve as critical operators to examine the theoretical and ethico-political displacements of psychoanalysis through the lens of the clinic with babies: Psychogenetic Baby, a trope that introduces psychoanalysis as a theory that, since its emergence, has led us to the terrain of childhood, revealing its traces in psychic constitution as testimony to the incidence of the Unconscious. Freud is understood not only to have enabled the formulation of a properly infantile psychopathological field but also to have inaugurated a new proposal for science. The clinic with children—and especially with babies— places tension on the psychoanalytic method, challenging its epistemological limits in a constant search for validation. Misunderstood Baby situates Lacan’s critique of the loss of theoretical specificity and ethical radicality promoted by certain post-Freudians, defining the status of the subject as an effect of language and rescuing the subversion promoted by psychoanalytic discourse as the privileged way to position the subject in relation to knowledge and truth. Neuroplastic Baby analyzes the incidence of neoliberal rationality and the neurodiscourse in contemporary readings of childhood. It problematizes how cerebralist logic, supported by the notion of neurodevelopment, reconfigures the idea of the subject and introduces the normative ideal of performance, culminating in the centrality of autism as a paradigmatic diagnosis. The thesis considers the not-all neurological status of this clinical structure and the ambiguous position of psychoanalysis in face of the “autism industry,” ranging from rejection to conciliation. Automaton Baby, in turn, interrogates the permeation of neurodiscourse in psychic constitution and early childhood care practices. It shows how the valorization of the “competent,” active, and autonomous baby ends up becoming a form of objectification and control. This figuration reveals the capture of psychoanalysis by neurodevelopmentalist and risk-prevention logics and symbolizes, thus, the neoliberal ideal of premature autonomy and the erasure of the bond with the Other through the overvaluation of expert knowledge about subjectivity. Finally, the last chapter proposes an inversion of the neoliberal logic that captures suffering and subjectivity under normalization criteria. By considering autism as a pathology of the social, it demonstrates how the shadow of this clinical picture extends to babies (and perhaps to fetuses) and definitively exposes an ideal of childhood, a mode of bonding, and a form of suffering typical of our times. Understanding that each psychoanalyst’s choice regarding the use of theory and its modes of transmission must be regarded as a political act, this work values the wager on the subject of the unconscious as that which escapes scientistic ambition and nosographic categorization. Sustaining the discussion on the decoloniality and demedicalization of childhoods will require recovering the subversive character of psychoanalysis, repositioning it in its extimate condition
Desempenho de genótipos de milho : tolerância salina, adubação, produtividade e bioatividade de Corymbia citriodora sobre Sitophilus zeamais
(Universidade Federal do Espírito Santo, 2024-12-20) Marcos, Rodrigues Agostinho; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador2; https://orcid.org/; http://lattes.cnpq.br/; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
Maize is a crop of food and economic importance worldwide, with the United States of America being the largest producers with 380,93 million tons and with a high average productivity of between 9 and 10 Ton/ha, exceeding 35 million, Brazil It is the second largest exporter and third largest producer of maize, behind only the United States and China. The State of Mato Grosso stands out with an average productivity of 6,338 kg/ha and production of 41,620,1 tons of grains, followed by Paraná, Goiás, Mato Grosso do Sul and Minas Gerais. The average productivity per maize area in the State of Espírito Santo is 2,955 kg/ha, ranking at the bottom. Among the problems that cause low maize production are inadequate fertilization management, the selection and planting of genetic materials susceptible to adverse environments (such as saline) and post-harvest pest infestation caused mainly by Sitophilus zeamais, responsible for grain losses and seeds. To prepare this research, 5 factorial experiments were prioritized, two (2) in the field and three (3) carried out in the laboratories of UFES-Alegre and Embrapa Milho e Sorgo. The objective of this research was to evaluate the physiological, morphological and productive performance of maize genotypes subjected to saline environment conditions, mineral fertilizer sources and alternative control of Sitophilus zeamais Motschulsky. The first chapter aimed to evaluate the effect of saline concentrations on seed germination and development of maize seedlings, and it was concluded that the best response to saline stress was obtained in the White genotype, in all variables evaluated. The second chapter evaluated the physiological and morphological behavior of maize genotypes in response to the application of mineral and organomineral fertilizers and it was concluded that fertilization with organomineral fertilizer provided similar responses when compared to complete fertilization - NPK. In the third chapter, the nutritional status and production of corn genotypes were evaluated based on the application of mineral and organomineral fertilizer, and it was concluded that the hybrid AG1051 and the varieties Branco, Roxo, Palha roxa and Vermelho showed higher grain productivity when they were fertilized with NPK. The fourth chapter aimed to evaluate the host preference of Sitophilus zeamais in stored maize seeds. And it was concluded that maize genotypes present different mechanisms of non-preference and oviposition by Sitophilus zeamais, with Roxo genotype standing out, which presented antixenosis resulting from the effect of nutritional properties and seed hardness. In the fifth chapter, the objective was to evaluate the effect of dosages of Corymbia citriodora powders on Sitophilus zeamais in the conservation of maize seeds and it was concluded that the interaction between Corymbia citriodora powders and genetic resistance of maize genotypes constitutes a sustainable strategy for efficient seed protection for family and organic farming

Artisanal fishing is a cornerstone of coastal communities in Espírito Santo, Brazil, providing a vital source of livelihood for numerous families. Its significance extends beyond economic aspects, encompassing cultural and social dimensions, forging a deep connection between communities and the environment. Despite its crucial role, the generation of waste from fish processing poses a significant challenge for the fishing sector. The current management of this waste is characterized by worrying irregularities, leading to substantial negative environmental impacts. This inadequate management not only jeopardizes the quality of marine ecosystems but also contributes to large-scale environmental manipulation. This research delves into the critical role of artisanal fishing in the environmental impacts associated with fishing activities in the municipality of Marataízes, Espírito Santo. The primary objective is to evaluate the environmental impacts resulting from the irregular disposal of waste from artisanal fishing in the Barra do Itapemirim and Pontal ports, located in the municipality of Marataízes. The methodology employed in this study integrates both qualitative and quantitative approaches. Initially, the evaluation of the artisanal fishermen's profile involved the application of questionnaires, following a documentary methodological approach. This stage encompassed aspects identified in the diagnosis, including the disposal of waste resulting from fish processing. To analyze the composition of the generated waste, physical, chemical, and nutritional characterizations were performed, providing a comprehensive understanding of the waste generated in the process. The results and analyses of this research enabled the characterization of the fishermen's profile and fishing activities in the studied communities. Furthermore, it was possible to understand the composition of fish waste, noting the significant presence of lipids, proteins, and energy. It was also identified that the continuous disposal of this waste is causing significant environmental impacts due to the high concentration of the parameters found. This made it possible to suggest measures for the reuse of this waste, such as the production of fishmeal, aiming to mitigate these impacts and promote a more sustainable use of available resources
Estado e fundo público: um estudo para o estado do Espírito Santo (2015–2022)
(Universidade Federal do Espírito Santo, 1900-01-01) Raft, Ana Clara Oliveira; Co-orientador1; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador2; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador3; https://orcid.org/; http://lattes.cnpq.br/; Co-orientador4; ID do co-orientador4; Lattes do co-orientador4; Orientador1; https://orcid.org/; http://lattes.cnpq.br/; Orientador2; https://orcid.org/; http://lattes.cnpq.br/; https://orcid.org/; http://lattes.cnpq.br/; 1º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 2º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 3º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 4º membro da banca; http://lattes.cnpq.br/; 5º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 6º membro da banca; https://orcid.org/; http://lattes.cnpq.br/; 7º membro da banca; https://orcid.org/; http://lattes.cnpq.br/
This dissertation analyses the budgetary policy of Espírito Santo from 2015 to 2022, through the lens of the State Derivation theory, and investigated how the functions and subfunctions of public spending reflect a logic oriented toward capital accumulation. Using official budget data re-grouped by functional classification of expenditure, the study articulates empirical analysis with the theoretical framework of the derivation school. The findings suggest that, despite shifts in political leadership, the core of fiscal policy remained structurally aligned with adjustment imperatives, favouring financial outlays and incentives to the private sector, while deprioritising key areas of social spending. The structure of state revenues reinforces this trend by granting tax exemptions without robust mechanisms for oversight and transparency, thereby deepening the regressive nature of the tax system. Ultimately, the Espírito Santo budget functions as an organic component of state policy—understood here as the expanded reproduction of capital—managing distributive tensions without overcoming them and revealing the persistence of a fiscal rationality largely impervious to partisan or conjunctural change.

Triangular carbon systems in single monolayer, also known as n-triangulenes (where n is the number of carbon rings at the base of the triangle), hold significant potential in nanoelectronics and spintronics applications due to their electronic structure and ground state multiplicity being dependent on the system’s size. However, controlling their high chemical reactivity at the edges, due to its zig-zag edge configuration, remains a challenge from an experimental standpoint. The strategy investigated in this study to address this characteristic is to create an insulating matrix of hexagonal boron nitride (h-BN) so that the triangulenes can be embedded in the h-BN structure, maintaining their electronic and magnetic properties. Given the size of the studied systems, the Density Functional Theory will be used in all electronic structure calculations. The results revealed that the formation of h-BN or carbon domains is equally possible, and the multiplicities of the ground state are determined solely by the carbon sites, regardless of their position, size, or whether the carbon islands are connected or not. Additionally, Lieb’s Theorem holds true in all cases when considering only the carbon sites, which can be a useful tool in determining the ground state spin of these systems

This is a Professional Master's Dissertation resulting from a study that aimed to investigate the judicialization of the admission processes for undergraduate programs at the Federal University of Espírito Santo (UFES). The need to reconcile the interest in accessing public higher education in Brazil with existing regulations, inclusion policies, and the State's budgetary constraints has increased the complexity of the admission processes. Simultaneously, the 1988 Federal Constitution expanded the possibilities for access to justice and the role of the Judiciary. In this context, the judicialization of admission processes has become a frequent trend, and UFES, particularly as the only public university in the state where it is located, is not immune to this phenomenon. The research is documentary, descriptive, and explanatory, conducted through a mixed-method approach. Quantitative and qualitative stages of document analysis were carried out on the judicial cases available on the virtual page of the Federal Regional Court of the 2nd Region, related to admission to UFES undergraduate programs. The results present an overview that highlights the increase in the number of lawsuits between 2018 and 2023, as well as the Judiciary's involvement in implementing public policy for higher education admission. The phenomenon predominantly involves sensitive issues, such as the quota system. Moreover, the analysis of the judicial decisions related to these cases demonstrates that there is no judicial activism in the content of the decisions, that the rulings are primarily based on factual matters and principled and jurisprudential arguments, and that UFES is the losing party in a minority of cases. However, the rulings against the University—especially those that provisionally mandate enrollment—have significant consequences for public administration and students. Therefore, the study of the judicialization phenomenon reveals weaknesses, potentialities, and solutions for public administration, making it possible to outline recommendations that contribute to improving the admission processes for undergraduate programs at UFES, in order to prevent recurring legal disputes.

Dominó Caníbal (2010), curated by Cuauhtémoc Medina, with the aim of understanding how curatorial choices can transform the exhibition space into a field of negotiation between aesthetic values and political tensions. Based on an analysis of the exhibition experience—understood as a sensitive laboratory in which artworks, environment, and interventions interact—the study proposes a critical reading of curatorship as an active device for the redistribution of the sensible, breaking with traditional narratives and hegemonic consensuses. Grounded in theoretical frameworks that engage with the perspectives of Jacques Rancière, Maria Lind, and other authors who address political aesthetics, the research analyzes how the contemporary curator operates not only in the formal organization of artworks but also in the construction of narratives that challenge the boundaries between the artistic and the political. Using a mixed methodology that combines documentary analysis, interviews, and case studies, the work highlights the relevance of the curator as an agent of cultural mediation. It thus contributes to broadening the debate around critical curatorship and the history of exhibitions, emphasizing its role in contesting structures of power and reconfiguring the practices of perception and experience of art

It is understood that school libraries are not mere complements, but fundamental elements of the pedagogical environment, whose presence is vital in the daily life of schools. However, achieving the universalization of these spaces has faced a series of practical challenges, with the shortage of properly qualified librarians being one of the main obstacles nationwide. These difficulties compromise the effectiveness of policies aiming to universalize school libraries, making it crucial to seek solutions to overcome these barriers. In this context, this study investigates the socio-educational role of reading rooms in municipal schools of Cachoeiro de Itapemirim/ES, as well as explores how librarians can contribute to managing these spaces, using librarian praxis as a central approach. The study diagnoses the current situation of the reading rooms, analyzes the actions taken, the professionals involved, the physical environment, management, and existing policies. It also examines the integration and participation of librarians in these rooms, comparing them with school libraries, and discusses how librarian praxis can be a differential in managing these spaces. To achieve these objectives, a mixed methodological approach is adopted, combining exploratory and descriptive elements. The research includes an initial literature and document review, followed by a mixed data collection to understand the dynamics of reading rooms in Cachoeiro de Itapemirim. Finally, a Case Study method is used to analyze the data obtained and formulate recommendations. Based on this knowledge, projects for reading rooms managed by librarians are suggested as a viable alternative to address the lack of qualified professionals. The results highlight the reading room as a sociocultural device and information center, emphasizing the importance of their management by qualified librarians. Furthermore, it underscores the value of librarian praxis for the development of reading rooms, with an emphasis on their sociocultural and critical dimensions

We observed a growing interest on the part of Basic Education students in topics related to Astronomy, contributing to this the wide dissemination of the Brazilian Astronomy and Astronautics Olympiad (OBA). The presence of Astronomy themes in official texts that refer to the curriculum, such as the National Common Curricular Base (BNCC) and the New Secondary Education, is also notable. This motivated us to propose didactic sequences, based on the Theory of Meaningful Learning (TAS), developed by David Ausubel and widely disseminated in Brazil by Marco Antônio Moreira, aimed at teaching Astronomy in Basic Education. We organize classes into didactic sequences according to themes related to the Solar System, in the form of Potentially Meaningful Teaching Units (PMTUS), seeking to promote not only conceptual learning, but investigative experiences that motivate the student to delve deeper and continue learning Astronomy. We applied our teaching proposal in a public school in the state of Espírito Santo, through an elective discipline, consisting of twenty-six students. The project took place over a period of nine weeks with two classes per week, totaling eighteen class hours. To investigate the students' prior knowledge and the existence of possible misconceptions, at the beginning of each class we apply a test related to the PMTUS theme in question. In addition to the tests, we observe students' externalizations through conversations in the classroom and dialogues in the WhatsApp’s group. At the end of applying the teaching proposal, we looked for signs of meaningful learning through the comparison of both results of the initial tests and the final test, we analyzed the dialogues in the group and the practical activities photos shared. We noticed an improvement in the final test's correct answer rates for some questions and, through the analysis of conversations and practices, we observed the commitment of the students, who went beyond what was requested, spontaneously recognizing some constellations, revealing signs of meaningful learning. The learning observed, the motivation, the interest aroused in the students during the practical activities of observing and recognizing stars in the sky, revealed in their statements, seem to indicate that the teaching units proposed and applied, to a large extent, proved to be potentially significant. We hope that our research and teaching proposal, consolidated in the educational product we present in the annex, the booklet “Guide for beginners and backpackers to the Solar System”, can bring contributions to other teachers and researchers involved in teaching Astronomy for Basic Education
Unraveling the Crato Formation's preservation and paleoenvironment through the lens of insect taphonomy

The Crato Formation (Santana Group, Araripe Basin, Brazil) is a well-known Konservat Lagerstätte that preserves a great number of various insect taxa that are exceptionally well preserved both in micro and macro scales. This unit represents a lacustrine paleoenvironment, and therefore, is also important for the study of aquatic insects and their interaction with this past environment. To date, only a few investigations have analyzed the general insect taphonomy of the Crato Formation so far, yet none used actualistic data, which we apply in the third chapter of the thesis. The first part of this thesis consists of a published paper containing the first detailed description of fossilized proventriculi from nine Grylloidea (Orthoptera: Ensifera) specimens of the Crato Formation. Based on the morphological and preservational signatures of the specimens, we bring new morphological data to explore the differences among extinct and extant taxa, that gives insight into the evolution and physiological development of Orthoptera, but mostly, about their exceptional preservation in this unit. The second part of this thesis presents a manuscript with the results on preservational modes of mayflies (Ephemeroptera) and crickets (Orthoptera) of the Crato Formation. We also present the modes of preservation of mayflies from the Solnhofen limestones (Upper Jurassic, Germany) for comparison. The majority of Crato specimens have several conserved external and internal microfeatures, and are preserved by replacement of the cuticle and of internal organs by iron oxides after pyritization, while the Solnhofen fossils are 11 preserved as impressions. In most Solnhofen fossils, their micron-scale morphology is obliterated by coarse mineral growth of calcite crystals. In general, Solnhofen fossils are complete, fully articulated, but with no submicron-scale replication of both external and internal morphology, and are extremely poorly preserved if compared to the insects of the Crato Formation. Lastly, the third manuscript presented in this thesis brings the results of experiments performed to determine the nature of the taphonomic processes and patterns which caused the state of preservation seen in the larvae of mayflies and dragonflies and adult mayflies preserved in the Crato Formation. Our results with experimentation show indications that carcasses of larval Hexagenitidae suffered little disturbance, typical of an autochthonous assemblage. We also noticed that adult fossil specimens with signs of longer decay time were extremely rare. The fossil dragonflies analyzed are preserved in a characteristic position that indicates minimal transport after death, which we find out after experiments with modern larvae. Data on disarticulation also suggest that the dragonfly gomphid larvae were not transported for long distances. Finally, our experiments have shown that when small insects, such as mayflies, die in sub-aerial conditions, there are few possibilities of overcoming the surface tension and sink. Thus, we believe microbial biofilms on the surface of the water were acting during carcass sinking in the Crato Formation
Vozes negras em movimento: reivindicações feministas e ancestrais nas performances do coletivo “Sarau das Pretas”

This research aims to analyze the literary and artistic production of the group Sarau das Pretas, created in Sao Paulo in 2016. It is composed by four black women and a trans man, all of them coming from the marginal spaces of the suburbs; the group is an interesting evidence of the actual landscape of Brazilian marginal literature’s dynamicity, particularly the feminine and black one. Its art combines many artistic languages like poetry, dance, and music. It offers considerations about black women’s identity, guided by themes such as the body, the feminine, the ancestry and the Afro-diasporic culture; it also reports the racism and the sexist violence in the Brazilian society. The Sarau is therefore configured as a space of black women’s protagonism through the stimulation of their literary and artistic production and the creation of an environment based on listening, dialogue, sharing and empowerment. Besides highlighting the group’s artistic quality – examined through the lenses of performance studies–, the objective of this research is underlining its political, social and cultural demands, as well as its messages of pride, respect and care for black identity.
