Item Produção de materiais adsorventes para remoção de nitrato em meio aquoso(Universidade Federal de Goiás, 2019-09-30) Araujo, Sara Sales de; Cuba, Renata Medici Frayne; http://lattes.cnpq.br/2178652705357657; Cuba, Renata Medici Frayne; Ostroski, Indianara Conceição; Scalize, Paulo SérgioNitrate contamination of surface and groundwater resources has been evident over the years, as high concentrations can cause adverse health reactions such as methemoglobinemia in newborns. In the study carried out in different Brazilian states, nitrate concentration levels above the maximum allowed for potability standards were determined, highlighted as 10mg. L-1 in the consolidation nº 5 of the Ministry of Health. In this context, there was an intensification of studies on the adsorption process using activated bichars and biosorbents, produced from agroindustrial residues to remove nitrate in aqueous medium. The use of corn cob as a precursor is favorable since the imminent generation of these residues. In this study, corncob was chemically modified with P.A. hydrochloric acid to obtain biosorbent (BS), activated biochar of oxidizing atmosphere (BCO) and activated biochar of inert atmosphere (BCI). For the prepared adsorbent materials their characteristics were determined, such as the zero charge point (pHpzc) assay which revealed for BS and BCO pHpzc 2.1, while the BCI was 6.3. In the Forrier Transform Infrared (FTIR) assay the adsorbent materials showed characteristic groups, such as carboxylic (3400 cm-1), methyl, methylene and methoxyls (2900cm-1), carbonyls (1700cm-1), aromatic rings (1600cm-1). Also, the adsorption conditions were optimized regarding the solution pH and adsorbent dosage, revealing solution pH of 2.0 for BS and BCO, and pH of 6 for BCI, and 0,75 g for BS and BCO, 1g for BCI. Adsorption isotherms and kinetics were determined, and Langmuir isotherm was better adapted for BS and Freundlich for BCO and BCI. The kinetics were pseudofirst order for BS and pseudo-second order for BCI and BCO. For the materials presented, removals were 6.16 mg.g -1 for BS, 13.33 mg.g -1 for BCO and 15.54 mg.g -1 for BCI.Item A nova retórica e a perspectiva dialogal nas redações do Enem(Universidade Federal de Goiás, 2020-03-23) Silva, Ana Gabriela Moreira e; Morais, Rubens Damasceno; http://lattes.cnpq.br/6418455746725194; Morais, Rubens Damasceno; Fernandes, Eliane Marquez da Fonseca; Piris, Eduardo LopesThe National High School Exam (Enem) has great relevance in the Brazilian scenario as it is the main means of access to universities. Given its importance, each year, as tests that become more complex and discussed by specialists in each of the areas of concentration of the exam. Such importance and attention given to Enem are many researchers who research on subjects to develop scientific research, mainly with regard to the exam writing test, which is the focus of this research. Therefore, this dissertation, entitled The new rhetoric and the dialogical perspective in Enem newsrooms, has as its object of analysis Enem newsrooms that get maximum marks in the period between the years 2015 to 2018, as well as the writing excerpts that were installed in the situation 'hurt human rights' in the same period, from 2015 to 2018. This is the case of an analysis of this corpus in the fundamentals, mainly in the Argumentation studies, more precisely, in the theory of the universal auditorium of Chaïm Perelman and Olbrechts- Tyteca (1996), in Christian Plantin's notion of interaction and argumentative argument. Discourse analysis, by Ruth Amossy (2016), will also be considered, as well as Bakhtin's (2009) notion of dialogue. In addition to these theorists, other references used, such as Aristotle and Goffman (2014), for example. Furthermore, the theoretical framework will be the basis for the analysis of the corpus, to demonstrate how the examination, without the context of Enem's wording, creates an image of its auditorium and writes its text based on the influence of the dissemination of the thousand note essays in the Enem Participant Primer. The second moment of the exhibition analysis, based on an execution that fits the situation 'hurt human rights', how an interaction occurs between the exam and the examining board at the time of the production and evaluation of the written essay, and how it materializes an interruption of argumentative stasis. For these two moments of analysis, in this qualitative quality research, the top and doxai concepts are used mainly, which, in general, refer to socially accepted opinions and the values that permeate society, respectively. With the analysis path, the role of the examining board was observed within the argumentative character of the Enem newsroom.Item A emergência do adolescente em conflito com a lei(Universidade Federal de Goiás, 2020-04-13) Tauhata, Thiago Brandão Vieira; Cassoli, Tiago; http://lattes.cnpq.br/3605178273280112; Cassoli, Tiago; Rodrigues, Divino de Jesus da Silva; Hur, Domenico UhngThis work seeks, through genealogical research, the emergency of the adolescent in conflict with the law, constituted by a critical reflection that allows an analysis of antagonisms involved on the execution of socio-educational measures inside the governmental plan. Starting from an analysis of the legal documents of the 19th century, going through the emergency of the minor as objects of law in the 20th century, in association with the hygienists and eugenicist knowledge of the abnormal child until contemporary times, we observe with the promulgation of the Statute of the Child and Adolescent the emergency of a character resulting from biopolitics technics to be governed according to neoliberal governmentality. This character is created over time according to these techniques that are linked to the concept of socio-education. An inaccurate concept, undefined, but through the analysis of texts elaborated by the pedagogue Antonio Carlos Gomes da Costa, responsible for the inclusion of the term in the Statute and strong influencer in socio-educational works, allowed us to observe the elements for the birth of adolescents in conflict with a law according to neoliberal entrepreneurship racionality. This rationality coordinates itself with the socio-educational practice, limiting the accountability to adolescents, often excluding a diverse range of chronic historical and social factors present in its constitution. This implies increasing absence of State responsibility at the same time that a much broader government over the adolescent in conflict with a law according to a calculation of their freedom and life. Keywords: adolescent in conflict with the law; minor; governmentality; biopolitics, neoliberalism.
