Co-polymerisation of α-styryl-poly(ethylene glycol)300, α,ω-bis(styryl)-penta(ethylene glycol) and 2,5-diphenyl-4-(4′-vinylbenzyl)oxazole in varying molar ratios resulted in the production of chemically functionalised scintillant-containing poly(oxyethylene glycol) polymer (POP-Sc) supports. These materials are compatible with both aqueous and organic solvents, and possess the ability to scintillate efficiently in the presence of ionising radiation, even after prolonged and repeated exposure to organic solvents. The utility of POP-Sc supports in both solid-phase peptide chemistry and a functional scintillation proximity assay has been exemplified.

The new engine plant by General Motors (GM) in Joinville-SC, inaugurated on February 27th 2013, incorporates the most advanced automotive technology processes and broad compliance with environmental standards and energy efficiency. The initiatives implemented in this industrial plant include processes with 100% of recycled industrial waste (landfill free) and pioneer systems in energy efficiency and environmental protection, qualifying the plant to obtain the global certification of Leadership in Energy and Environmental Design (LEED). This industrial project reveals the strategic importance of the region and of Brazil in the growth of GM in the world, becoming a reference for studies and project evaluations of "green" factories in the automotive sector. The present study performs an exploratory research based on scientific publications, assessing the direct and indirect impacts on the business outcome, resulting from implementation of industrial serviceoriented sustainability of its operations, referred to in this article as "Green Factory”. We concluded that the adopted technologies focused on sustainability, study and development, represent a new step for the design of new plants and future expansions of the company in the region, combining low operating cost, low environmental impact and conservation of natural resources.

Cognitive radio (CR) was developed for utilizing the spectrum bands efficiently. Spectrum sensing and awareness represent main tasks of a CR, providing the possibility of exploiting the unused bands. In this thesis, we investigate the detection and classification of Long Term Evolution (LTE) single carrier-frequency division multiple access (SC-FDMA) signals, which are used in uplink LTE, with applications to cognitive radio. We explore the second-order cyclostationarity of the LTE SC-FDMA signals, and apply results obtained for the cyclic autocorrelation function to signal detection and classification (in other words, to spectrum sensing and awareness). The proposed detection and classification algorithms provide a very good performance under various channel conditions, with a short observation time and at low signal-to-noise ratios, with reduced complexity. The validity of the proposed algorithms is verified using signals generated and acquired by laboratory instrumentation, and the experimental results show a good match with computer simulation results.

The consequences resulting from economic modernization model generated social and environmental imbalances, resulting in the exclusion and social isolation, perceived consequences in the agricultural sector. When studying social organizations, tends to see how they keep their forward cooperation processes all a company incorporated by the appreciation of individualism and competition. The overall objective for this research was to analyze the organizational dynamics of Agroecology Group Heritage Viva Chapecó, Santa Catarina, in order to identify the strengths and threats and collaborate in this way for preparation of action strategies for sustainability. The selected group is based on the principles of agroecology for the conduct of their agricultural production systems, avoiding the use of agrochemicals, proven through the use of participatory certification seal Ecovida Network, and the products sold mainly in street fairs in the city of chapecó. To fulfill such a proposal were consulted the minutes of meetings and questionnaires with farmers to assess the dynamics of cooperation among its members, through the understanding of their social capital and social network analysis (SNA). To extend the study of the group and its members was adopted methodological approach of action research where activities were developed to identify strengths and weaknesses and contribute to its organizational restructuring, resulting in the construction, carried out by farmers, the guiding principles of the Living Heritage Group will contribute to the decision-making and strengthen their identity. The survey also brought the group is inserted in the Social Transition Agroecology therefore change the current paradigm is not inserted only in the alternative model of production, but in the form of organization of social actors and their role in the marketing process of their products, in discussing the scenario of food supply chains.

This thesis deals with the insertion of family farmers market that act as market traders in the city of Chapecó, state of Santa Catarina. In order to trust, reciprocity and relations of time and space dynamics present in the practice of open-air market is analyzed. From understanding the outdoor market as an extension of the activities of farms, a form of local construction market, we need new ways to evaluate the inclusion of family farming in trade. In this regard, the importance of local markets characterized by autonomy in the food hegemonic system. To this end, it uses what the peculiarities present in the practice of street fairs, its historical development, the number of farmers who act as market participants, the number of traders in the city and its surroundings, the diversity of products offered, the marketing channel access by traders and market relations farmers who act as market participants. Finally, based on the responses of suppliers and content analysis, it was possible to show how present in the social dynamics of free trade: the trusted face to face representations, reciprocity and relations of time and space between the co-present agents in the market dynamics of family farmers fair. For the study context, these representations show how important non-economic values that help build identities that relate to the strategies of social reproduction and overcoming dominant market model.
