In this work, motivated by experimental evidence of ARPES carried out by our collaborators at UFES, theoretical electronic structure calculations were carried out about the electronic and topological properties of bismuth selenide, Bi2Se3, doped with aluminum. A brief review of the literature is presented on the bases for the Density Functional Theory (DFT) and how this approach is built within the Born-Oppenheimer approximation. In addition, a discussion is made regarding the topology of materials and their main mathematical entities, with the aim of understanding some properties of topological materials. The artifices used to confirm the topologically non-trivial character of Bi2Se3 underwent calculation of the topological invariant Z2, in addition to the analysis: 1) of the surface states; 2) the orbital composition of the band inversion around the Γ point; and 3) the band structure for a system with few layers. Following these steps, it was possible to infer the role of the substitution of Bi by Al in the insulator Bi2Se3

This dissertation delves into the study of Markov chains, evolutionary processes characterized by “memory loss”, widely applied in diverse fields such as biology, statistics, and finance. The convergence of these chains to a stationary distribution is analyzed using the “total variation distance”. The times of 𝜀-mixing are introduced, representing the time required for convergence. The concept of coupling between Markov chains is presented, demonstrating its utility in de termining bounds for mixing times. The phenomenon of cutoff, an abrupt decrease in total variation distance, is explored, providing a detailed understanding of convergence. The ulti mate goal is to calculate the cutoff profile for the simple exclusion processes on complete graphs. Chapters cover the construction of chains, technical concepts, couplings, and mixing times, cul minating in the analysis of the cutoff phenomenon and its specific application to the exclusion process in the complete graph

Promovendo a alfabetização científica, a interdisciplinaridade e o protagonismo estudantil no ensino médio por meio da bioquímica em um livro interativo digital
(Universidade Federal do Espírito Santo, 2024-03-27) Dazzi, Bruna Jejesky; 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/
Biochemistry is an interdisciplinary science that combines at least two major areas of scientific knowledge: Biology and Chemistry. Teaching Biochemistry in high school is challenging for both teachers and students, requiring the use of different methodological approaches. This includes, for example, interdisciplinary experiments with the encouragement of investigative strategies, contributing to facilitate the teaching-learning process of students. In this sense, this Master’s Thesis (TCM) presents a Digital Interactive Book (DIB), “The scientist girl in: the cell and the biomolecules - a digital book for the teaching of biochemistry by investigation”. It tells the story of a girl named Ana who collects mysterious particles in her backyard, generated by an explosion, and identifies them with the help of her teacher. Fourteen experiments are developed over fifteen chapters, presented in experimental investigative scripts that work with Biochemistry content in an interactive and interdisciplinary way. The material was designed to be used by Biology and Chemistry teachers with high school students and can be easily adapted for science teachers to use in elementary school. The tool has the potential to develop interdisciplinary teaching through Biochemistry, based on the proposition of hypotheses and the use of Experimental Investigative Scripts. In addition, the TCM presents to teachers a model of an elective discipline entitled “Scientific Literacy” placed in an Instruction Guide as a Supplement to the DIB, with a suggestion of using the scripts in a sequential and structured way. Also, the product pays tribute to pioneering women scientists in Brazil through the characters that refer to their surnames, reinforcing the important female presence in science. Finally, the didactic resource of this TCM aims at the construction and understanding of scientific thinking by developing scientific literacy, interacting Chemistry and Biology through Biochemistry, placing students of different levels as protagonists in the teaching-learning process

This research is the result of theoretical and practical research developed in the Master's Course of the Graduate Program in Teaching and Basic Education at the Federal University of Espírit Holy. It aims to understand the training processes of teachers, their pedagogical practices and the knowledge that mobilize and constitute the teaching work at the State School of Fundamental Education Settlement Unity, Conception of Bar, State of the Spirit Holy. It arose out of anguish and uneasiness when listening and witnessing the impacts caused by the interference of the State/ SEDU in the training processes of Pedagogy of Alternation in the Settlement Schools of the Movement of Rural Workers (MST). The theoretical contribution of this research is mainly based on the studies of Tardif (2002) and GAULTHIER et al (2013), among other authors that made it possible to deepen and reflect on the theme. The methodological mechanisms adopted are guided and associated with the theoretical framework selected through the narrative approaches of Souza (2004, 2007) and the qualitative research proposals of exploratory character by Gil (2002, 2008). Various instruments are used to reach the practices and voices spoken by the subjects involved, both individually and collectively in their daily activities and in listening to the specificities of Rural Education. The text is organized in chapters that reflect on the historical path of struggles for the reformulation of the teacher training curriculum from the end of the 1970s and start in 1980 onwards. Rural Education, following a discussion of teacher training in the daily life of the profession and the specificity of Rural Education and the particularity of the School of Fundamental Education Settlement Unity, and the analysis and interpretation of data. The results indicate as practical and pedagogical experience of Pedagogy of Alternation that Rural Education and teacher training are the basis for the construction of educational practices aimed at professional, pedagogical and political training in the context of Rural Education

This work intends to answer how the dystopia 1984, written by George Orwell, can contribute to readers' ability to understand, beyond the surface, contemporary social phenomena. The objective of the research was to reflect on the role of the dystopia literary genre in the formation of critical readers. The hypothesis constituted is that the dystopia literary genre, even if written more than seventy years ago, as is the case in 1984, when describing social organizations characterized by intolerable living conditions, manages to criticize trends in current society, as it invites readers to broaden their reflection on contemporary social phenomena. The methodology is based on a qualitative research perspective, with an interpretative analysis of the book 1984, by George Orwell, based on concepts such as spectacle society and cultural industry, based on dialogue with the tradition of critical theory of society, inaugurated by the Frankfurt Institute for Social Research
