13. ALLOCATION OF FIRM ENERGY RIGHTS AMONG HYDRO PLANTS: A GAME THEORETIC APPROACH / APLICAÇÃO DE TEORIA DOS JOGOS À REPARTIÇÃO DA ENERGIA FIRME DE UM SISTEMA HIDRELÉTRICO
The objective of this work is to investigate the application of different methodologies of allocation of firm energy rights among hydro plants using a gametheoretic framework. It is shown that there is not an optimal and unique approach to make this allocation but there are criteria to verify if a given approach presents any inadequate aspect. One of these c

14. STRATEGIES TO EXPLORE NUCLEAR-ELETRIC ENERGY IN BRAZIL / ESTRATÉGIAS PARA GERAÇÃO DE ENERGIA NUCLEOELÉTRICA NO BRASIL
Since 1996, the basic structure of the Brazilian electric sector has been changing dramatically. However, these changes have not brought great improvement in terms of electric energy diversification, considering that the sector`s energetic matrix is basically concentrated in a single source - the hydraulic. The objective of this study is to develop an analyt

15. A cogeraÃÃo como difusÃo de um processo de inovaÃÃo tecnolÃgica e estratÃgica empresarial no setor sucroalcooleiro: o caso da Destilaria Giasa
This Dissertation is a qualitative research with the purpose of exploring and understanding the changes envolving the Destilaria Giasa, considering the diffusion process of a technology innovation in the case of a familiar enterprise inserted in sugar cane industry. In a short definition, cogeneration is a combined heat and power production (CHP), correspond

16. Aproveitamento da energia hidroeletrica secundaria para produção de hidrogenio eletrolitico
In hydroelectric systems, during the rainiest periods of the year, there is surplus hydropower in the reservoir, some ofwhich is commercialized (secondary hydroelectric power) and the rest spills over producing no power. A manner of utilizing such lost power is converting it into an energy carrier, as, for example, electrolytical hydrogen. In this study such

17. Desenvolvimento de um produto desidratado combinando pescado salgado com uma base proteica obtida de farinhas de soja e trigo
The present work was undertaken with the aim of developing a dehydrated product (fish-balls) by combining defatted soy flour, wheat flour and minced salted fish. Defatted soy flour and wheat flour were mixed at levels of 1.0 : 1.0 , 0.75 : 1.0 , 0.50 : 1.0 and 0.5 : 1.0 parts respectively, leavened with 6% of commercial yeast for 45 minutes, baked at 200-210

18. A multiscale model for tropical intraseasonal oscillations
The tropical intraseasonal 40- to 50-day oscillation (TIO) is the dominant component of variability in the tropical atmosphere with remarkable planetary-scale circulation generated as envelopes of complex multiscale processes. A new multiscale model is developed here that clearly demonstrates the fashion in which planetary-scale circulations sharing many fea

19. Dynamics of the interaction between a fibronectin molecule and a living bacterium under mechanical force
Fibronectin (Fn) is an important mediator of bacterial invasions and of persistent infections like that of Staphylococcus epidermis. Similar to many other types of cell-protein adhesion, the binding between Fn and S. epidermidis takes place under physiological shear rates. We investigated the dynamics of the interaction between individual living S. epidermid

20. Chemical exchange 2D IR of hydrogen-bond making and breaking
The involvement of chemical exchange in 2D IR heterodyne echo spectroscopy is characterized through the hydrogen-bond exchange between CH3OH and the CN of CH3CN. The exchange dynamics on the hydrogen-bond potential surfaces associated with different quantum states of the high-frequency CN stretching mode contributes to strong cross peaks between CN groups in

21. Cellular levels, excretion, and synthesis rates of cyclic AMP in Escherichia coli grown in continuous culture.
Changes in dilution rate did not elicit large and systematic changes in cellular cyclic AMP levels in Escherichia coli grown in a chemostat under carbon or phosphate limitation. However, the technical difficulties of measuring low levels of cellular cyclic AMP in the presence of a large background of extracellular cyclic AMP precluded firm conclusions in thi

22. Employers, the government, and industrial fatigue in Britain, 1890-1918.
The evolution of the concept of industrial fatigue and the responses of employers and the government in Britain to research initiatives in this field of industrial medicine up to the end of the first world war is explored. The discussion dovetails in with the broader debate about the characteristics and dissemination of scientific labour management in Britai
