In the 18th century period, several mathematicians contributed to the development of Infinitesimal Calculus (IC). Among the exponents of this context, Joseph-Louis Lagrange (1736 – 1813) and Lazare Nicolas Marguerite Carnot (1753 – 1823) stood out. Thus, as a research question, the present work raised the following problem: what points of closeness and distance do the works Réflexions sur la Métaphysique du Calcul Infinitésimal (RMCI), of 1813, by Lazare Carnot, and Théorie des Fonctions Analytiques (TFA), of 1813, by Lagrange, present, concerning the concepts of the Infinitesimal Calculus? To answer it, we used the methodological contributions of content analysis as well as the steps established in Bardin (2016), adapted for this research. Therefore, this thesis aimed to compare, based on content analysis, the approximations and detachments between the works RMCI and TFA. With this, we realized, as approximations, that both perform descriptions about their concepts and definitions and involve the same problems with the infinitesimals about the infinitely large and infinitely small quantities. As detachments, we observe that the central elements in Lagrange's work are functions and series and only the algebraic method is under discussion, while in Carnot's work infinitely small quantities and the theory of error compensation are present, and it conceives the use of infinitesimals without disregarding the other methods.

Discurso e cibercultura: uma análise de como a imagem Amazônia é disseminada em âmbito da internet
(Universidade Federal do Pará, 2021-04-20) ARAUJO, Daymerson Ferreira; PIRES, Yomara Pinheiro; http://lattes.cnpq.br/5304797342599931; https://orcid.org/0000-0001-7724-6082
Amazon is not now the space where the attention of governments, governmental and nongovernmental organizations, national and international, and various institutions is turned. Given its complex sociobiodiversity, images and visions are built on this region, which, in most cases, serve to disseminate and consolidate exogenous speeches and which end up being received and assimilated by inhabitants of this region, especially by those who have easier access and use of the world wide web, a privileged environment for the creation and circulation of ideas. Thus, the following questions arise: how do 2nd year high school students from a private school in Castanhal / PA understand the Amazon through contact with these speeches and ideas disseminated on the internet? In this sense, the general objective of this research is to analyze, through its textual productions, the way high school students from a school in Castanhal / PA perceive the Amazon theme in the context of the internet. Specifically, it aims to: a) Identify and characterize the Amazonian space in geographic, social and environmental spheres, seeking to understand its place in the economic context, both in the past and in the present; b) Analyze the emergence of the world wide web as a possible vector for the dissemination and consolidation of discourses today; and c) Understand and analyze how the Amazon is perceived by high school students, from the internet, using Content Analysis and Discourse Analysis of texts produced by them. This study is justified by the fact that the internet is today the areopagus where debates take place in an agile and integrated way and understanding how these students retain such information for themselves is important for decision-making, especially with regard to to more specific interventions within the school and society. Thus, content analysis (CA) is used as methods of analysis, following bardin’s (2016) and discourse analysis (AD) assumptions, based on reflections by Althusser (1967), Orlandi (2007) and Souza (2014). This research is part of a qualitative-interpretative nature (MINAYO, 1995), of a basic nature (JACOBSEN, 2009). As results, it was understood that most of the research participants have a perception of the Amazon as an external environment to their coexistence, as a scenario that is limited, solely and exclusively, to the forest, to exoticism. Furthermore, a posture of distancing in relation to the Amazon was identified in most of their speeches.
