Beyond the global, the source, the origin, and the influence : notes on the differential comparison method.
No full textEste artigo visa problematizar algumas noções próprias da literatura comparada, firmadas pela crítica e pela teoria literária, assim como intensificar a complexa relação entre o global, o universal e o internacional no confronto com a cultura. Para tanto, recorre-se ao método da comparação diferencial e seus múltiplos modos de conceber a dinamicidade dos gêneros, dos mitos e dos textos em um regime de migrações e de contaminações cada vez mais atrelados à cultura e aos efeitos de sentido por ela reivindicados e produzidos. Busca-se, ainda, elencar alguns agenciamentos que tornam o texto, o mito e o signo artístico cada vez mais diaspórico, cruzado e fronteiriço.This article aims to problematize some specific notions of the comparative literature, established by criticism and literary theory, as well as to intensify the complex relationship between the global, the universal, and the international confrontation with the culture. The method of differential comparison is used and has multiple ways of conceiving the dynamics of genres, myths, and texts in a regime of migrations and contaminations increasingly linked to culture and the effects of meaning claimed by it and produced. It also seeks to list some assemblages that will have made part of the text, the myth, and the artistic sign increasingly diasporic, crossed and border

From catenoids to nodoids : the classification of Delaunay surfaces.
No full textO objetivo deste estudo é apresentar e analisar as superfícies de Delaunay, que são superfícies de revolução com curvatura média constante. Utilizando métodos de geometria diferencial, investigamos as propriedades das curvas geradoras que definem essas superfícies e exploramos suas características geométricas e analíticas. Classificamos as superfícies de Delaunay como cilindros, esferas, catenoides, nodoides e onduloides. Estas superfícies são reconhecidas como soluções elegantes e práticas para problemas de estabilidade e fenômenos na biologia celular. Concluímos que o estudo das superfícies de Delaunay enriquece a compreensão teórica da geometria diferencial e oferece aplicações práticas valiosas em diversas disciplinas científicas.The aim of this study is to present and analyze Delaunay surfaces, which are revolution surfaces with constant mean curvature. Using differential geometry methods, we investigate the properties of the generating curves that define these surfaces and explore their geometric and analytical characteristics. We classify Delaunay surfaces as cylinders, spheres, catenoids, nodoids and onduloids. These surfaces are recognized as elegant and practical solutions for stability problems and phenomena in cellular biology. We conclude that studying Delaunay surfaces not only enriches the theoretical understanding of differential geometry but also offers valuable practical applications in various scientific disciplines
A basis- and integral-free representation of time-dependent perturbation theory via the Omega matrix calculus.
No full textWe obtain a basis- and integral-free representation of the n-term in time-dependent perturbation theory of the quantum time-evolution operator. The main technical tool to construct the aforementioned representation comprises the Omega matrix calculus; that is, an exten sion of MacMahon’s partition analysis to the realm of matrix calculus. In particular, we show that if we specialize our formulation to the time-independent and finite-dimensional case, we recover Putzer (1966) original formulation to compute the matrix exponential avoiding the Jordan canonical form. Furthermore, if we use an explicit basis for the time-independent part of the generator of evolution, then our work implies a representation of the perturbation expansion similar to an approach discussed in the recent work of Kalev and Hen (2021) using divided differences. Finally, we obtain closed form expressions which generalize and unify all the perturbation calculations considered in Kalev and Hen (2021) and advance some considerations regarding degeneracy associated with the unperturbed Hamiltonian in the context of adiabatic switching
Prefabrication : the concept, its use and some disagreements in Brazilian scientific production.
No full textNeste artigo propõe-se problematizar distintos entendimentos do termo pré-fabricação adotados na literatura científica nacional recente e recuperar uma definição para o conceito a partir de suas práticas históricas — como uma relação temporal e espacial de organização do trabalho no processo produtivo. Por meio de Análise de Conteúdo são examinados e sistematizados trabalhos científicos (artigos, dissertações, teses, monografias, livros e capítulos de livros) dos campos da arquitetura e da engenharia, publicados entre os anos de 1996 e 2019, de forma a permitir inferências ao seu contexto social de forma objetiva. Como resultado, são explicitados pontos conflitantes em meio a produção científica analisada, ressaltada a relevância da clareza do conceito de pré-fabricação para vislumbrar seus potenciais como procedimento construtivo e indicadas possibilidades para novas práticas e historiografiasIn this article we aim to scrutinize various interpretations of the term prefabrication as adopted in context national scientific literature and to derive a definition for the concept based on its historical practices — viewing it as a temporal and spatial arrangement of labor organization within the production process. Employing Content Analysis methodology, with the objective of drawing objective inferences regarding their social context, we examine and systematize scientific works (articles, dissertations, theses, monographs, books, and book chapters) from the fields of architecture and engineering, published between 1996 and 2019. As a result, conflicting points within the analyzed scientific production are elucidated, the importance of conceptual clarity in understanding prefabrication’s potential as a construction procedure is underscored, and avenues for new practices and historiographies are suggested
Qualitative and quantitative changes in mitochondrial DNA associated with cervical cancer : a comprehensive review.
No full textCervical cancer is the fourth most commonly diagnosed cancer in women and is considered a preventable disease, as vaccination and screening programs effectively reduce its incidence and mortality rates. Disease physiopathology and malignant cell transformation is a complex process, but it is widely known that high-risk HPV (hrHPV) infection is a necessary risk factor for cancer development. Mitochondria, cell organelles with important bioenergetic and biosynthetic functions, are important for cell energy production, cell growth, and apoptosis. Mitochondrial DNA is a structure that is particularly susceptible to quantitative (mtDNA copy number variation) and qualitative (sequence variations) alterations that are associated with various types of cancer. Novel biomarkers with diagnostic and prognostic value in cervical cancer can be evaluated to provide higher specificity and complement hrHPV molecular testing, which is the most recommended method for primary screening. In accordance with this, this review aimed to assess mitochondrial alterations associated with cervical cancer in clinical cervicovaginal samples, in order to unravel their possible role as specific diagnostic and prognostic biomarkers for cervical malignancy, and also to guide the understanding of their involvement in carcinogenesis, HPV infection, and disease progression
Weight regain after bariatric surgery : a systematic review and meta-analysis of observational studies.
No full textDue to its significant impact on public health, obesity has been studied from a variety of perspectives. All surgical procedures of bariatric and metabolic surgeries (BMS) carry their risks and benefits and have specific characteristics. Considering that weight regain (WR) is considered a surgical failure. This systematic review, registered on PROSPERO under code CRD42023421203, aims to identify physical and behavioral predictors associated with WR post-BMS. Primary outcomes included WR prevalence after BMS (>10% recovery from maximum weight loss or points of BMI >4 or 5 kg/m2), while secondary outcomes assessed factors associated with WR. This systematic review with meta-analysis demonstrated that 49% of patients WR after BMS and this prevalence is higher in those who underwent Roux-en-Y Gastric Bypass (RYGB) surgery (42%) and in Europe (64%). Protective factors for WR only included prior BMI and younger age with
statistical significance, however other analyzes did not demonstrate statistical significance.
Therefore, it is important to note that the use of BMS does not guarantee long-term sustainable
weight loss without continuous lifestyle modifications and treatment dietetic. Efforts to maintain
weight loss should include ongoing lifestyle modifications to ensure the effectiveness and efficacy
of the surgery
O sistema de justiça criminal como óbice à participação da mulher autora de crimes no processo penal e as contribuições e desafios da justiça restaurativa para um novo modelo de justiça.
No full textPrograma de Pós-Graduação em Direito. Departamento de Direito, Escola de Direito, Turismo e Museologia, Universidade Federal de Ouro Preto.O sistema de justiça criminal brasileiro orienta-se a partir de uma perspectiva androcêntrica,
reproduzindo uma lógica de dominação masculina, de forma que as mulheres que integram o
processo penal na condição de pessoas acuadas sofrem com a violência institucional desse
sistema, que aprofunda as desigualdades estruturais existentes na sociedade. Assim buscou-se
revelar as funções reais do sistema de justiça criminal e, a partir disso, traçar diretrizes para a
solidificação de um novo modelo de justiça alinhado com o Estado Democrático de Direito.
Com o auxílio de uma Criminologia Crítica e Feminista, pretende-se demonstrar as finalidades
reais do sistema penal, evidenciando os obstáculos que as mulheres autoras de crimes
encontram no âmbito do processo penal brasileiro e que impedem a sua participação efetiva na
gestão do conflito. Ademais, propõe-se uma análise acerca das possíveis contribuições da
Justiça Restaurativa para romper com o modelo de justiça autoritário, androcêntrico e opressor.
Partindo da premissa de que as práticas restaurativas podem ser implementadas em qualquer
fase do processo, por meio da realização de entrevista semiestruturada com um(a) facilitador(a)
que atua no projeto de Justiça Restaurativa recentemente implementado no âmbito do sistema
prisional mineiro, pretende-se avaliar a viabilidade de expansão das práticas para outras fases
processuais, bem como para outros estados de Minas Gerais. A configuração atual do processo
penal brasileiro impede que as partes tenham a oportunidade de expor suas narrativas, suas
expectativas e anseios com relação ao processo, o que reproduz as violências estruturais, as
discriminações e as estigmatizações em detrimento de grupos sociais vulneráveis. Para tanto,
adotou-se como marco teórico a noção de processo penal democrático, no intuito de
compreender a importância de se ampliar e ressignificar o sentido conferido ao contraditório,
previsto na Constituição Federal de 1988, a fim de que o processo não seja um instrumento de
opressão e que imponha o silenciamento em detrimento das mulheres autoras de crimes. Com
o desenvolvimento do estudo proposto, almeja-se traçar diretrizes em busca de um novo modelo
de justiça que, inspirado na Justiça Restaurativa, seja voltado para a responsabilização,
reparação e reintegração, com o objetivo de compreender e respeitar as relações sociais afetadas
pelo delito.The Brazilian criminal justice system is oriented from an androcentric perspective, reproducing
a logic of male domination, so that women who are part of the criminal process as cornered
people suffer from the institutional violence of this system, which deepens inequalities structure
existing in society. Thus, we seek to reveal the real functions of the criminal justice system and,
based on this, outline guidelines for the solidification of a new model of justice aligned with
the Democratic Rule of Law. With the help of Critical and Feminist Criminology, the aim is to
demonstrate the real purposes of the penal system, highlighting the obstacles that women
perpetrators of crimes encounter within the scope of the Brazilian criminal process and that
prevent their effective participation in conflict management. Furthermore, an analysis is
proposed on the possible contributions of Restorative Justice to break with the authoritarian,
androcentric and oppressive model of justice. Starting from the point that restorative practices
can be innovative at any stage of the process, by conducting a semi-structured interview with a
facilitator who works in the Restorative Justice project recently implemented within the scope
of the Minas Gerais prison system, we intend to evaluate the prediction of expansion of
practices to other procedural phases, as well as to other states of Minas Gerais. The current
configuration of the Brazilian criminal process prevents the parties from having the opportunity
to expose their narratives, their expectations and desires regarding the process, or from
reproducing structural violence, discrimination and stigmatization to the detriment of
vulnerable social groups. To this end, we developed the notion of democratic criminal process
as a theoretical framework, without the intention of understanding the importance of expanding
and re-signifying the meaning given to the contradictory, provided for in the Federal
Constitution of 1988, so that the process is not an instrument of oppression and that imposes
silencing to the detriment of women perpetrators of crimes. With the development of the
proposed study, the aim is to outline guidelines in search of a new model of justice that, inspired
by Restorative Justice, is focused on accountability, accessories and reintegration, with the aim
of understanding and respecting the social relationships affected by the crime

No full textObjetivo: Analisar o Plano Municipal de Saneamento (PMSB) do município de Ouro Preto, buscando sugerir seu
aperfeiçoamento diante de eventuais lacunas identificadas.
Referencial teórico: A Lei n. 14.026 (2020), que atualiza o marco legal do saneamento básico, estabelece
diretrizes nacionais para o setor, cita a elaboração do Plano Municipal de Saneamento Básico (PMSB) como
instrumento de planejamento.
Método: O processo metodológico procedeu-se em duas etapas, sendo, respectivamente, de caráter exploratório e
qualitativo, dados por estudo documental e análise por meio da lista de verificação (checklist). Esses checklists
são constituídos por um conjunto de categorias, divididas em subcategorias, das quais foram analisados os
componentes do saneamento, assim como os princípios fundamentais.
Resultados e Conclusão: O levantamento dos checklists possibilitou constatar as seguintes lacunas no Plano, a
saber: Políticas como combate à pobreza e sua erradicação; política e plano de prevenção de riscos e desastres, e
política de gênero e promoção da igualdade. Conclui-se que o PMSB do município de Ouro Preto necessita de
maiores investimentos quanto as componentes do saneamento, sobretudo o de drenagem, associando-se aos
princípios fundamentais, de modo a contribuir sobretudo com a universalização dos serviços.
Implicações da Pesquisa: O estudo indica lacunas da legislação frente ao PMSB de Ouro Preto, sendo uma base
para futuras versões.
Originalidade/valor: A pesquisa é dada como um estudo de caso onde os princípios fundamentais indicados na
Lei n.14.026 (2020), que é recente, são avaliados. É fundamental que as cidades sejam analisadas quanto a seus
instrumentos urbanos sob essa ótica.Purpose: To analyze the Municipal Sanitation Plan (PMSB) of the municipality of Ouro Preto, seeking to suggest
its improvement in the face of any identified gaps.
Theoretical framework: Law no. 14.026 (2020), which updates the legal framework for basic sanitation,
establishes national guidelines for the sector, and cites the preparation of the Municipal Basic Sanitation Plan
(PMSB) as a planning instrument.
Method/design/approach: The methodological process proceeded in two stages, being, respectively, exploratory
and qualitative in nature, data through documentary study and analysis through the checklist. These checklists are
made up of a set of categories, divided into subcategories, from which the sanitation components were analyzed,
as well as the fundamental principles.
Results and conclusion: The checklist survey made it possible to identify the following gaps in the Plan, namely:
Policies such as combating poverty and its eradication; risk and disaster prevention policy and plan, and gender
policy and promotion of equality. It is concluded that the PMSB in the municipality of Ouro Preto needs greater
investments in terms of sanitation components, especially drainage, in association with fundamental principles, in
order to contribute above all to the universalization of services.
Research implications: The study indicates gaps in the legislation regarding the Ouro Preto PMSB, providing a
basis for future versions.
Originality/value: The research is given as a case study where the fundamental principles indicated in Law no.
14.026 (2020), which is recent, are evaluated. It is essential that cities are analyzed regarding their urban
instruments from this perspective
Synthetic peptides selected by immunoinformatics as potential tools for the specific diagnosis of canine visceral leishmaniasis.
No full textDiagnosing canine visceral leishmaniasis (CVL) in Brazil faces challenges due to the limitations regarding the sensitivity and specificity of the current diagnostic protocol. Therefore, it is urgent to map new antigens or enhance the existing ones for future diagnostic techniques. Immunoinformatic
tools are promising in the identification of new potential epitopes or antigen candidates. In this study, we evaluated peptides selected by epitope prediction for CVL serodiagnosis in ELISA assays. Ten B-cell epitopes were immunogenic in silico, but two peptides (peptides No. 45 and No. 48) showed the best performance in vitro. The selected peptides, both individually and in combination, were highly diagnostically accurate, with sensitivities ranging from 86.4% to 100% and with a specificity of approximately 90%. We observed that the combination of peptides showed better performance when compared to peptide alone, by detecting all asymptomatic dogs, showing lower cross-reactivity in sera from dogs with other canine infections, and did not detect vaccinated animals. Moreover, our data indicate the potential use of immunoinformatic tools associated with ELISA assays for the selection and evaluation of potential new targets, such as peptides, applied to the diagnosis of CVL
