Os cães de trenó na Terra do Fogo (Argentina) e o que eles têm a nos ensinar sobre o trabalho animal

This dissertation is the result of field research whose objective was to study the relationships between humans (especially mushers and tourists) and sled dogs – which are, from the mushers’ perspective, working dogs – in tourism in Ushuaia (capital of Tierra del Fuego province/Argentina), focusing the ethnography on the practical and semiotic relationships involved in sled rides, dog breeding and the small local sled race, Encuentro Musher. Beyond sled dogs, however, in Tierra del Fuego I came across with several other dogs in other contexts, such as the stray dogs on the streets of Ushuaia and the “wild dogs” – which are a major socioeconomic problem and, therefore, are subject to being eliminated. In this sense, I suggest that in fuegian lands the different statuses of dogs (ranging from domestic/working to wild/feral to interstitial categories) fluctuate according to the existence (or not) of a social “function”, meaning animal work. Thus, I argue that in this context it is only possible to think of sled dogs by reflecting on these other dogs that make up the relationships between humans and animals in this part of the planet. This dissertation’s scope was, then, the elaboration of a multispecific ethnography that took into account both humans and dogs (and sleds), as well as a reflection on animal work, its possibilities and its limits.
Potencial de utilização de resíduos de filmes poliméricos e de fibras de vidro provenientes do processo de fabricação de pás eólicas

The investments made in wind energy have been growing globally over the years, aiming at sustainable alternatives for the segment. However, this growth carries with it an increase in the consumption of production materials and wastes from its processes, which if not properly treated cause negative impacts to the environment. In a society increasingly attentive to ecological issues, concepts of reuse and recycling have been widely disseminated as ways of mitigating the aggression caused by the incorrect disposal of materials in the environment. Thus, in order to contribute to the sustainability of wind turbine manufacturing processes, this study investigates opportunities to reuse two types of waste from these industries: vacuum infusion polymer films and stitched and random glass fiber fabrics. Due to unsatisfactory initial results presented when using these materials together in the hot compression molding process, it was necessary to use them separately and in different molding processes. The first part of the study investigates alternative recycling of polymeric vacuum bag films that are discarded after the manufacturing process of wind turbine blades. The work involved the reuse of this type of polymer film by means of a hot molding process in a hydraulic press. After molding, the plates were cut into specimens for mechanical evaluation in flexural and impact tests and for Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The results indicated that the waste analyzed is polyamide (nylon) and its mechanical properties are close to the properties mentioned in the literature for this type of polymer, being indicated for use in molding and/or machining of objects such as bearings, gears, rollers, guides and various pieces of industrial equipment. In the second part, the study proposes an alternative method for the reuse of glass fiber wastes (stitched and random) in the manufacture of new thermosetting polymer composites. Here, stitched fabrics from manufacturing processes were used, as well as material refused for technical non-compliance. Ten composites with different layers and fabric arrangements were prepared, which were mechanically evaluated in flexural and tensile and thermally by thermogravimetric analysis (TGA). The preparation process used was the resin transfer molding (RTM) whereby the polymer resin is suctioned into the fiber reinforcements, giving rise to the composites. The resin used in the moldings was the unsaturated polyester type of trade name Arazyn 13.0. Finally, the statistical analysis of mechanical results, performed according to Tukey's methodology, revealed that the number of glass fiber layers is determinant for mechanical properties of the composite, whereas the orientation of the fabrics inside the composites does not present significant differences. Depending on the application of the composites, if higher or lower mechanical resistance is required, other arrangements can be analyzed in order to obtain the desired properties. The composites developed can be applied as materials to obtain products such as doors, floors, walls, office partitions and other furniture with flat surface.
Plano de Gerenciamento Integrado de Resíduos Sólidos de Campina do Monte Alegre, SP
(Universidade Federal de São Carlos, 2019-11-08) Boniolo, Vinicius Rainer; Grigoletto, Fábio; https://lattes.cnpq.br/2398917544592259; Periotto, Fernando; https://lattes.cnpq.br/8301456352208939; https://lattes.cnpq.br/8757447264574231
It was proposed here to characterize the municipal solid waste collection system of the municipality, to diagnose the solid waste generated or administered containing the origin, volume and characterization of waste, including related environmental liabilities, to understand the possibilities of environmentally appropriate final destinations, identify consortium or shared solutions with other generators, propose preventive and corrective actions to be performed in situations of mismanagement or accidents, and propose routes for the collection of domestic solid waste and for selective collection. Thus, with the theoretical framework raised and the various results obtained in this work, an important theoretical tool was developed so that the Municipal Plan of Integrated Solid Waste Management of Campina do Monte Alegre will be put into practice in the near future. This research will certainly help the fulfillment of the propositions foreseen over the next years, however, it is known that the implementation of this Plan will depend on political articulations of the municipal public management in question. Its implementation will be of great importance, as it will bring positive consequences, leading the municipality to social inclusion and will significantly reduce the environmental impacts caused by improper disposal of waste. Reflections of the results of this work will be achieved over the years, that is, in the medium or long term, as there are specific goals to be met in different sectors of the city hall, with different schedules. Finally, it can be stated that the management plan will contribute to the municipality in question to comply with the Law, and to broaden respect for public health, technical, environmental, social and administrative issues
