1. Assessment of the Potential Implementation of Solar Energy Generation in State Schools in Curitiba/PR
ABSTRACT Solar energy as a form of electric power generation is gaining ground in Brazil, being the subject of worldwide discussions on sustainability. The electric energy, a right of all citizens, represents a consumption of natural resources on a large scale. State schools in Paraná invested more than R$ 46 million to guarantee electricity and thus provid

3. Implementação e avaliação de desempenho de estratégias de controle aplicadas em um sistema de armazenamento refrigerado / Implementation and performance evaluation of control strategies applied in a storage system for refrigerated
The cold storage of agricultural products intended to meet a demand for healthier products by markets and consumers. You can also give producers an alternative to extend the time for the marketing of products stored. Cold storage is important for a better conservation of perishable products. Because with the decrease in storage temperature, the metabolic rea

4. New concept of space radiator with variable emittance
A new concept of space radiator of variable emittance for satellite thermal control is presented. The radiator is composed of two stages which exchange heat through radiation between finned surfaces covered with variable emittance coatings, whose emissivity is increased with temperature. Under cold conditions the radiative heat coupling between the stages is

5. USE OF EXPANDERS FOR GENERATING ELECTRICAL ENERGY IN NATURAL GAS PRESSURE REDUCTION STATIONS / USO DE EXPANSORES PARA GERAÇÃO DE ENERGIA ELÉTRICA EM ESTAÇÕES DE REDUÇÃO DE PRESSÃO DE GÁS NATURAL
The natural gas is compressed to high pressures in order to be transported in the gas pipeline and delivered to the clients at lower pressures, using pressure reduction control valves in an adiabatic process. It can be shown that the same natural gas thermodynamic output state is achieved if the control valves can be substituted by expanders, producing work

7. Uma contribuição a analise de conservação de energia eletrica utilizando a teoria dos conjuntos Fuzzi
A methodology for decision-making in studies involving energy saving by using the Fuzzy Sets Theory is presented. The Fuzzy Sets Theory permits to handle and to operate exact and non-exact propositions, that is, to incorporate both numerical data (exact) and the knowledge of either the expert or the analyst (inexact). The basic conceptsof this theory are pre
