13. CONTINUED FRACTIONS: ERGODIC AND APPROXIMATION PROPERTIES / FRAÇÕES CONTÍNUAS: PROPRIEDADES ERGÓDICAS E DE APROXIMAÇÃO
We study the theory of continued fractions emphasizing the interaction between theory of numbers (expansion of numbers, diophantine approximations, best approximations) and ergodic theory. We study the Gauss transformation and construct its ergodic measure. Using the Birkhoff Ergodic Theorem we obtain results about the expansion in continued fractions of alm

14. InteriorizaÃÃo industrial no CearÃ: Estudo comparativo da regiÃo de Sobral e Crajubar - perÃodo de 1985 a 2003 / Industrial internalization in the CearÃ: Comparative study of the region of Sobral and Crajubar - period of 1985 the 2003
The importance of a government policy focused on fostering sectors of the economy, specially the industrial sector, has played an important role in the growth process and regional economy development. In what concerns to the state of CearÃ, FDI/PROVIN can be cited as the major example of a financial instrument to attract industrial projects. The government`

15. Codigos sobre grafos que são quocientes de reticulados
Graphs which are quotients of lattices are studied in this dissertation and some of their connections to error correcting codes are explored. The text is organized as follows. In Chapter 1 the main concepts and results in Graph theory are introduced. Chapter 2 contains s brief introduction to error correcting codes theory and Chapter 3 is devoted to the stud

16. THURSTON GEOMETRIES AND SEIFERT FIBER SPACES / GEOMETRIAS DE THURSTON E FIBRADOS DE SEIFERT
We begin by studying orbifolds, i.e., topological spaces locally homeomorphic to quotients of Rn by finite groups. Then we study Seifert fiber spaces of dimension three which are certain type of foliations by circles that can be seen as fiber bundles over orbifolds. This material is useful in the subsequent study of Thurston model geometries. A Thurston mode

17. Physiological and technological studies of fresh-cut cauliflower and salad rocket. / Estudos fisiológicos e tecnológicos de couve-flor e rúcula minimamente processadas.
This work aimed at evaluating the effects of temperature on the metabolism of minimally processed and intact cauliflowers and salad rockets, and of different packaging materials on the quality of cauliflower florets and loose salad rocket minimally processed leaves. In the first experiment, intact cauliflowers, florets, intact salad rockets and loose salad r

18. The Rate of Photorespiration as Measured by Means of Oxygen Uptake and Its Respiratory Quotient
Oxygen recycling inside photosynthesizing leaves was found to amount to less than 0.3% of the oxygen consumed by photorespiration under natural conditions, provided the influence of buildup of oxygen released by photosynthesis into the external air was taken into consideration. When this is related to the amounts of photorespired CO2, which had been previous

19. A new class of counterexamples to the integrability problem
For many years, it was believed that the solvability of the integrability problem for a transitive Lie pseudogroup depends only on the local solvability of linear differential operators arising from the abelian quotients in Guillemin's Jordan-Hölder decomposition for the transitive Lie algebra associated to the pseudogroup. We provide an example of a transi

23. Steady-state coupling of four membrane systems in mitochondrial oxidative phosphorylation.
According to Alexandre, Reynafarje, and Lehninger, four different membrane systems are involved, with definite stoichiometry, in the mitochondrial synthesis of ATP by electron transport, via proton transport. We adopt this model and pursue some of its thermodynamic consequences. At steady state, each of the four systems must have the same flux J through the

24. L2-cohomology of arithmetic varieties
The L2-cohomology of arithmetic quotients of bounded symmetric domains is studied. We establish the conjecture of Zucker equating the L2-cohomology of these spaces to the intersection cohomology of their Baily-Borel compactifications.
