25. Unemployment insurance an analysis of optimal mechanisms under aggregate shocks
The purpose of this work is to provide a brief overview of the literature on the optimal design of unemployment insurance systems by analyzing some of the most influential articles published over the last three decades on the subject and extend the main results to a multiple aggregate shocks environment. The properties of optimal contracts are discussed in l

26. Algoritmo para frenagem regenerativa de uma máquina síncrona de imã permanente / Algorithm for regenerative braking of a permanent magnet synchronous machine
Environmental protection and optimal energy resources are great activity research areas. As a result of these researches, electric vehicles (EVs) and hybrid (HEV) developments have been accelerated. They have challenging problems such as low autonomy, power conversion, vehicle control, energy management and distribution within it, as well as the esthetic and

27. An estimation method for gate delay variability in nanometer CMOS technology
In the nanoscale regime of VLSI technology, circuit performance is increasingly affected by variational effects such as process variations, power supply noise, coupling noise and temperature changes. Manufacturing variations may lead to significant discrepancies between designed and fabricated integrated circuits. Due to the shrinking of design dimensions, t

28. Testing the Optimality of Aggregate Consumption Decisions: Is there Rule-of-Thumb Behavior?
Consumption is an important macroeconomic aggregate, being about 70% of GNP. Finding sub-optimal behavior in consumption decisions casts a serious doubt on whether optimizing behavior is applicable on an economy-wide scale, which, in turn, challenge whether it is applicable at all. This paper has several contributions to the literature on consumption optimal

29. Analyze performance of capillary tube in small refrigeration system varying the speed compressor / Análise de desempenho do tubo capilar num sistema de refrigeração de pequeno porte com variação da velocidade do compressor
The need to reduce energy consumption in refrigeration and air conditioning is a priority for the refrigeration industry. This has encouraged the development of refrigeration systems more efficient and offer better performance. In this context, increases the importance of applying new technologies to a deeper understanding of these systems and the improvemen

30. Carvão vegetal e siderurgia: de elo perdido a solução para um mundo pós-Kyoto / Charcol based iron &steelmaking: from primitive technological model to solution for a post-Kyoto world
In a global-warming-frightened world, the positive carbon balance of charcoal-based iron &steel making recovers it from a past outshined by the dominance of the large fossil fuel mills. Nevertheless, the risk of not being able to profit from the global decarbonization consensus is material, owing to the dependency on deforestation. This is true even being th

31. Analise das estrategias da pesca do camarão de São Francisco, São Sebastião-SP : pela Teoria do Forrageio Otimo / Analysis of the strategies of shrimp fishing in São Francisco, São Sebastião-SP : through the Optimal Foraging Theory
This study uses ecological models derived from the Optimal Foraging Theory (OFT) to understand the decision-making processes among bottom trawling shrimp fishermen at the São Francisco Neighborhood, in the district of São Sebastião, SP, Brazil. Using the theoretical background of Human Behavioral Ecology the aim of this work was to analyze fishermen s str

32. Cultivo de bactérias redutoras de sulfato (BRS) e sua aplicação na biorremediação de efluentes ácidos contendo metais
Sulfate Reducing Bacteria (SRB) can be used as a promise and attractive biotechnology based alternative to promote passive treatment of industrial effluents. Sulfate is reduced to sulfide while organic matter is oxidized producing carbonate and bicarbonate ions. Treatment efficiency however depends on pH and metals content of the selected effluent and also o

33. Amino acids requirement and soybean meal in juvenile dourados Salminus brasiliensis (Cuvier, 1816) nutrition / Exigência em aminoácidos e farelo de soja na nutrição de juvenis de dourado Salminus brasiliensis (Cuvier, 1816)
Only a few research report address dietary amino acids requirement of Brazilian fish; this is true especially in regard to dourado, Salminus brasiliensis (Cuvier, 1816), a migratory, carnivorous Characin, which is not only the largest scale fish of the Prata Basin but also a prized aquaculture and sport fishing species. This study address dietary amino acids

34. Mixture experiments and their applications in welding flux design
The traditional welding flux development has been by cost, material, time and labour intensive experiments. The extensive and expensive trial and error experimentation is needed because it is often difficult to know a priori how the flux ingredients interact to determine the operational characteristics of the flux and the final performance of the welded stru

35. Destilado da desodorização do oleo de soja como suplemento de vitamina E / Soybean oil deodorizer distillate as a vitamin E supplement
Increased use of industrial waste and byproducts fits the need of industry to comply with environmental rules. The substitution of natural products for artificial ingredients has gained worldwide attention in the food, pharmaceutical and other industries. These facts justify the study on the utilization of Soybean Oil Deodorizer Distillate (SODD) as tocopher

36. Dynamics and control of heat exchanger networks / Dinamica e controle de redes de trocadores de calor
Energy integration among chemical process streams can lead to quite complex heat exchanger networks (HEN) with difficulties in terms of controI. In this work HEN dynamics and steady state aspects were addressed with the aim of proposing a control strategy that minimizes utility consumption and satisfies imposed specifications. A steady state model of the HEN
