Casa de tèranga: nomeações e materialidades da migração transnacional entre Senegal e Brasil

The Senegalese present on the streets of the city of Passo Fundo (RS/Brazil) have called my attention since 2010, when I joined the University of Passo Fundo as a professor. By attending Sunday muslim meetings, I realized the challenges of these displacements in living long years away from my family. The argument that I develop in this thesis is that the Senegalese family is constituted in the displacements of the subjects, from the materialities of the relationships and naming processes, in the tangle of places inhabited in their settlements, in which the tèranga (which can be translated as hospitality and honor) is a fundamental element, more than the house as a physical space. The field research was developed as a multi-sited ethnography, having two territories as a starting point, Passo Fundo (RS/Brazil) and Dakar (Senegal), but it was not restricted to them. In Brazil, it was carried out from Passo Fundo, accompanying the Senegalese in Porto Alegre and São Paulo (from January to August 2019), and in Senegal (from September 2019 to March 2020), departing from Dakar, traveling across 9 cities. Ethnography continued as a mesh, from the notion revisited by Ingold in the reticular trails left by the Senegalese as they follow their life in the keur (house), in their places of settlement, with multiple entanglements, with apparent permanence and solidity, in an ecceity experienced in the panoramas and transitions taken by the inhabitants.
Aplicação do combustível derivado de resíduos (CDR) para otimizar o uso da palha de cana e casca de eucalipto como fonte de energia térmica

Refuse derived fuel (RDF), characterized as part of municipal solid waste (MSW), is the leftover from the recycling process of waste not yet disposed of in landfills. The cement industry already uses RDF in natura as part of an alternative source of fuel to reduce CO2 emissions. The objective was to investigate the production of mixtures, through agglutination and/or extrusion of RDF with sugarcane straw and RDF with eucalyptus bark to optimize their energy use. Seven flakes-type treatments were produced through the extrusion process (granules of mixtures of RDF with undefined biomasses and formats): T1 (100% RDF), T2 (90% RDF and 10% bark), T3 (75% RDF and 25% bark), T4 (50% RDF and 50% bark), T5 (90% RDF and 10% straw), T6 (75% RDF and 25% straw) and T7 (50% RDF and 50% straw) and six pieces-like treatments (compacted material from mixtures of RDF with undefined biomass and formats), following the same proportions (from T2 to T7). The results showed that the density of the treatment produced in flakes format (RDF with straw) was approximately 10 times greater than RDF (in natura). The moisture of the flakes treatment (RDF with bark), compared to the bark, achieved a reduction of 83%. The higher heating value (HHV) of the treatment (RDF with bark) was 30% higher than the bark. The results indicated the real possibility of producing mixtures between RDF and biomass, by extrusion process. The result is a better quality solid fuel: more homogeneous, lower humidity, higher HHV and easier storage and handling.
