While taking paths from the archive to the new, this dissertation reflects on the resulting impacts of the introduction, massification and dissemination of digital technology, in the way we store and deal with information, inside the complex that we understand as culture. To this end, a theoretical investigation is performed in order to build a conceptual body from which concepts are drawn in order to effectuate a practical research. The theoretical research starts with an exordium in which the concept of the archive is deconstructed in order to identify it as a device of power and to analyse its transition from a technical analog object into a digital technology. Following this, a historical context is established, drawing on the evolution of power exercises and apparatuses, and a reading of the impacts of the present technological mediation on experience, knowledge cons¬truction and forms of control is developed. Finally, some hypotheses on the evolution of technology are formulated. The practical research materializes in the form of a digital platform which takes place in two moments: one of archive, the other of program. The first moment, of archive, con¬sists of a repository of projects dealing with the dissertation’s subject. The second moment, of program, is configured as a cultural program implemented through computer programs. These, in their execution, result in performances which, taking from the information col¬lected on the archive generate a new experience of that same information. To this effect, a framework was structured in order to have computational processes systematized in a way that the performances result in experiences with a potential for novelty, expression and reflection. Both theoretical and practical components of the research seek to address digital technology not as an end in itself, but as a factor that affects human experience and behaviour

Temos assistido nos últimos anos à proliferação da produção distribuída de electricidade, sobretudo, com recurso a fontes de energia renováveis, implicando a natural reestruturação das redes eléctricas existentes, desde a produção até ao consumidor final. As constantes preocupações na garantia da qualidade de serviço e até mesmo em termos ambientais, levam a que a operacionalidade das redes seja cada vez mais eficiente, visando a integração de tecnologias emergentes como é o caso dos sistemas de armazenamento de energia. A aposta nas energias de origem renovável nomeadamente a solar e a eólica, representa uma forma cada vez mais presente de geração de electricidade, tendo como grande inconveniente o regime de intermitência a que estão sujeitas, não se conseguindo tirar proveitos absolutos de todas as potencialidades que estas fontes proporcionam. Existem actualmente sistemas de armazenamento de energia que permitem optimizar o comportamento das redes. Nesta dissertação é feita uma abordagem a alguns desses sistemas, tendo como objectivo principal a demonstração das potencialidades de optimização dos sistemas de produção e distribuição de energia eléctrica com recurso a sistemas de armazenamento de energia, em redes isoladas e interligadas. É também feito um estudo do comportamento dinâmico de uma rede com vários cenários de ocorrência de defeitos, com e sem armazenamento de energia. Para isso a base deste trabalho consistiu na familiarização com uma ferramenta de grande potencial na simulação dinâmica de redes eléctricas, utilizado por prestigiados grupos de energia a nível mundial, na qual foi implementada a rede de teste e efectuadas as simulações do estudo.

Molybdenum is one of the essential micronutrients for soybeans, acting directly on nitrogen metabolism as enzyme cofactor of nitrogenase. Usually, this nutrient is supplied to the plants through seed treatment or foliar application. The aim of this study was to evaluate the molybdenum effects by foliar in the physiological potential of soybean seeds and verify its interference in the enzyme activities involved in nitrogen metabolism. Soybean seeds of BMX Turbo cultivar were used, produced in Erechim, RS, harvest 2013, from plants treated with the following Mo concentrations: 0; 25; 50 and 75 g ha-1, supplied through two commercial products (Biomol and Molybdate) and stored during 0 and 6 months in uncontrolled conditions. The first experiment was conducted in Seedtes Seed Analysis Laboratory in Pato Branco, PR. The used design was completely randomized in a factorial analysis 4 x 2 x 2 with four replications each. The physiological potential of the seeds was evaluated by the germination test, seedling growth, accelerated aging and emergence on the soil. The second experiment was conducted in a greenhouse, where the seeds derived from treatments with different concentrations of Mo: 0; 25; 50 and 75 g ha-1 supplied through two commercial products (Biomol and Molybdate) were grown in vases. The used design was completely randomized in a factorial analysis 4 x 2 with four replications. Evaluations were performed when the plants reached the R1 phenological stage concerning the nodulation, dry matter of root and shoot of the plants and the determination of the activity of the enzymes glutamine synthetase and glutamate synthetase and the content of total soluble proteins. The data were submitted to variance analysis and when significant they were assessed by Tukey’s test for comparison of products and seed storage and with regression study to the concentrations at 5% probability. Analyses were performed using SISVAR statistical software. The soybean seed storage under uncontrolled conditions affected the seed vigour produced with Mo, regardless of the commercial product used during production. The application of Mo through foliar positively influences the production of soya beans which presented increasing responses in the germination and vigour with the application of Mo above 25 g ha-1 . The enrichment of Mo through foliar did not affect the nodulation of plants of the next generation, however, the use of Mo above 25 g ha-1 provided an increase in the activity of enzymes involved in nitrogen metabolism as well as on the total protein content.

La codorniz “coturnix coturnix japónica”, es una especie que ha venido tomando auge en nuestro medio por ser un ave con esas características. La presente investigación fue analizar el efecto de diferentes niveles de harina de maíz amarillo mezclado con alimento concentrado comercial, en la nutrición de codorniz, en la etapa de desarrollo e inicio de postura, para ello se evaluaron 4 tratamientos: Tratamiento 1 = 100% de concentrado comercial de desarrollo de la marca Aliansa, Tratamiento 2 = 75% de concentrado comercial de desarrollo de marca Aliansa y 25% de harina de maíz amarillo, Tratamiento 3 = 50% de concentrado comercial de desarrollo marca Aliansa y 50% de harina de maíz amarillo, Tratamiento 4 = 25% de concentrado comercial de desarrollo marca Aliansa y 75% de harina de maíz amarillo.
