Eficiência fotoquímica e carboidratos foliares de clones de Theobroma cacao L. sob diferentes regimes de luz em sistemas de cultivo
(Universidade Federal do Espírito Santo, 2025-08-11) Vitoria, Jan da; Arantes, Sara Dousseau; https://orcid.org/0000-0001-6202-4153; http://lattes.cnpq.br/6966978781439168; https://orcid.org/0009-0006-6353-1388; http://lattes.cnpq.br/2801301509481679; Oliveira, Vinicius De Souza; https://orcid.org/0000-0003-4068-1587; http://lattes.cnpq.br/7213222193584056; Dias, Carla da Silva; https://orcid.org/0009-0005-6102-6057; http://lattes.cnpq.br/0497776503129914
The aim of this study was to evaluate the physiological and biochemical responses of Theobroma cacao L. leaves grown under different light conditions (full sun, Cabruca and agroforestry system – AFS), focusing on chlorophyll a fluorescence, photosynthetic pigments and non-structural carbohydrates. The clones PH16, PS1319 and CEPEC 2002 were analyzed over the course of one year. The results revealed that the AFS and Cabruca systems favored photochemical efficiency, with higher values of Fv/Fm and Y(II), while full sun induced partial photoinhibition, mainly during peak light hours. Total chlorophyll content was higher under shade, especially in PS1319 in the AFS. In contrast, PH16 maintained high values even under full irradiance, evidencing greater tolerance to light stress. Sucrose accumulation varied between clones and environments, with emphasis on PH16 in SAF and PS1319 in Cabruca. Multivariate analysis (PCA) confirmed the physiological separation between clones and the influence of the environment on photosynthetic efficiency. The results indicate that clones PH16 and PS1319 present high physiological and biochemical plasticity, being promising for systems with different light regimes.

Estudo da reatividade de defeitos topológicos no SiC 2D
(Universidade Federal do Espírito Santo, 2025-06-03) Almeida, Eduardo Ahnert Rodrigues de; Paz, Wendel Silva; https://orcid.org/0000-0001-5737-0633; http://lattes.cnpq.br/8332147920469110; http://lattes.cnpq.br/5468735492074356; Spalenza, Wesley; https://orcid.org/0000-0001-9644-3938; http://lattes.cnpq.br/2687428810786056; Belich Junior, Humberto; https://orcid.org/0000-0002-8795-1735; http://lattes.cnpq.br/3879935393431243; Pansini, Fernando Néspoli Nassar; https://orcid.org/0000-0001-8984-686X; http://lattes.cnpq.br/7331959117489023
In this study, we employed first-principles calculations based on Density Functional Theory to investigate the interaction of diatomic molecules (CO, NO and SO) with two-dimensional SiC monolayers containing 5-8-5 linear defects (585-ELD). Our results indicate that pristine 2D SiC exhibits a band gap of approximately 2.5 eV, while the presence of the 585-ELD introduces electronic states associated with pz orbitals near the Fermi level. Upon characterizing the adsorption of the molecules on 2D SiC with the 585-ELD, the Electronic Density of States (DOS) calculations revealed the formation of hybrid orbitals, indicating a chemisorption process. The calculated adsorption energies were-0.45 eV (CO),-1.38 eV (NO), and-2.88 eV (SO), with respective charge transfers of 0.40|e|, 1.37|e| and 1.71|e| to the molecules, thus characterizing strong chemisorption. We conclude that while this high affinity favors sensor sensitivity, it may hinder molecule desorption and consequently compromise its reusability. For future perspectives, we propose investigating the effects of mechanical strain on the material, using other external stimuli, and extending the study to other molecular species.

Elas no Ticumbi: bionarrativas das festeiras do Sapê do Norte
(Universidade Federal do Espírito Santo, 2025-10-10) Silva, Marlúcia Olímpio da; Costa, Eliane Gonçalves da; https://orcid.org/0000-0002-8820-1063; http://lattes.cnpq.br/8903022966748790; https://orcid.org/0009-0003-3005-2063; http://lattes.cnpq.br/7944957305584602; Santos, Záira Bomfante dos; https://orcid.org/0000-0002-6162-8489; http://lattes.cnpq.br/4736245340980339; Almeida, Carla Verônica Albuquerque; https://orcid.org/0000-0003-2330-1538; http://lattes.cnpq.br/1334298845911044
This study aimed, in general, to analyze the bionarratives of Quilombola women in the participation and maintenance of the Festa do Ticumbi. This research sought to map the role of these women in the organization and execution of the Ticumbi, examining how food sharing and preparation relate to cultural identity and Black resistance. The specific objectives were: to map the role of Quilombola women in the organization and execution of the Ticumbi; to examine how food sharing and preparation relate to cultural identity and Black resistance; and to integrate the bionarratives into the context of Afro-Brazilian dance, music, and religiosity. The analysis of the bionarratives provided an in-depth understanding of cultural practices and the challenges faced in preserving traditions, suggesting the need for public policies that support the appreciation and protection of Quilombola culture. The theoretical framework of this research found support in authors from anthropology cultural, sociology, and studies on quilombos, quilombola communities, and festivals, whose social production can generate elements such as the strengthening of identity through the sharing of symbols, in this case, the festivals that take place in these territories as a form of resistance and visibility for these groups. They are: Bhabha (2010); Geertz (1997); Bessas and Kato (2024); Kato (2020); Hall (2006); Canclini (2008); and Gilroy (2001). The research methodology used a qualitative approach, with data collection techniques that included narrative interviews, participant observation, and document analysis. The study also highlighted the importance of education as a tool to promote the appreciation of quilombola traditions, as well as addressing an combating racism in its various forms and manifestations. The results revealed that women play central roles in the organization and execution of Ticumbi, being fundamental for the intergenerational transmission of knowledge and practices.

Germinar territórios de vida em contextos de luta por moradia : resistência e aquilombamento da Ocupação Vila Esperança
(Universidade Federal do Espírito Santo, 2025-10-24) Miranda, Guilherme Corrêa; Co-orientador1; Orientador1; https://orcid.org/; https://orcid.org/; 1º membro da banca; 2º membro da banca; 3º membro da banca
This dissertation proposes to accompany processes of aquilombamento that germinate from existence and resistance within the context of an urban occupation and the struggle for housing. To this end, we seek to operate with an expanded conception of aquilombamento , drawing particularly on the contributions of Beatriz Nascimento and Abdias do Nascimento, who offer critiques of the hegemonic historiographical conception that attributes to the quilombos a strictly archaeological condition, fixed in the past. Thus, through this broadening, we aim to weave threads of connection between aquilombamento territories and housing occupations, in light of the delineation of the categories of affection, care, and ancestral wisdom. The Vila Esperança Occupation is the territory where this research unfolds. Located in the municipality of Vila Velha, part of the Metropolitan Region of Greater Vitória (RMGV) in the state of Espírito Santo, the occupation began in 2017. Due to the high housing deficit, combined with the health crisis caused by Covid-19, the occupation expanded, sheltering approximately 800 families by 2025, according to residents’ reports. Situated on an extensive plot surrounded by environmental preservation areas, the occupation faces the pressures of an intense land conflict in the region. Indeed, the entanglement of the forces of the State, the real estate market, and the judicial system imposes a grammar of violence materialized through police repression, real estate financial capital, and legal discourse — all working toward the eviction of residents from the self-built and occupied territory. In this sense, the analyses presented here focus on the period of intensification of the territorial dispute, resulting from the judicial decision ordering the population’s eviction. Through a participatory methodological approach centered on the processes that germinate from/in the lived ground — that is, the relations that make it possible to sustain a living territory — we seek to give shape to the aquilombamento processes cultivated during critical moments of attack and dismantling, as well as during the reclaiming of Vila Esperança, following the Supreme Federal Court (STF) decision to suspend the repossession order. Furthermore, grounded in the experience of Vila Esperança, we highlight the importance of occupations as spaces of belonging and protection in the face of capitalist-colonialist logics of urban production

Bebê como método : psicanálise, neoliberalismo e produção de subjetividade

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
