13. Memória jurídica : a linguagem processual dos crimes de estrupos, sob a ótica da estilística léxica
This thesis analyzed the processual language of the crimes of rape reported in the County of Cornelio Procopio, from the 1950s until 2001, to identify and describe the use of discourse-stylistic arrangements and as a result, assess its consequences and to check linguistic evolution experienced in this type of discourse. Knowing the historical position of sch

14. Modelo de sistema de comunicações digital para o mecanismo de importação de proteinas mitocondriais atraves de codigos corretores de erros / Digital communication system model for mitochondrial protein import by use of error-correcting codes
One of the puzzling problems in mathematical biology is to show the existence of any form of error-correcting code in the DNA structure. Using information theory considerations we propose a model for the biological coding system similar to that of a digital communication system. This model consists of a mapper (transformations from the set of nucleotides eit

15. Genetic programming: crossover operators, building blocks and semantic emergence / Programação genética: operadores de crossover, blocos construtivos e emergência semântica
Evolutionary algorithms are heuristic methods used to find solutions to optimization problems. These methods use stochastic search mechanisms inspired by Natural Selection Theory. Genetic Algorithms and Genetic Programming are two of the most popular evolutionary algorithms. These techniques make intensive use of crossover operators, a mechanism responsible

16. A trama da vida
On the basis of the knowledges are fragmented and placed in watertight compartments, this thesis proposes that art, by its transdisciplinary characteristics, may contribute to bridging, to make reconnections, entanglement. The complex thinking is the inspiration and literature was the method chosen to shows this possible dialogue. The narrative is woven by f

17. QUANTUM-INSPIRED LINEAR GENETIC PROGRAMMING / PROGRAMAÇÃO GENÉTICA LINEAR COM INSPIRAÇÃO QUÂNTICA
A superioridade de desempenho dos algoritmos quânticos, em alguns problemas específicos, reside no uso direto de fenômenos da mecânica quântica para realizar operações com dados em computadores quânticos. Esta característica fez surgir uma nova abordagem, denominada Computação com Inspiração Quântica, cujo objetivo é criar algoritmos clássico

18. Optimization study of airfoil performance using genetic algorithms / Otimização de desempenho de aerofólios supercríticos: uma abordagem baseada em algoritmos genéticos
The objective of present study is analyze the multi-objective optimization applied to transonic airfoils project comparing different ways to define the objective functions. The optimization is evaluated by the genetic algorithm NSGA-II. The results is analyzed using metrics of diversity and optimality for multi-objective problems, which two are proposed. The

19. A escolarização dos conteúdos imagéticos da biologia: um estudo das práticas de construção e execução de aulas pelo professor de biologia
This investigation aims to understand role of the teacher on the schools practices of transmission of the biological sciences images contents inside the classrooms. For this were identified and described teacher practices in the class, the functions developed by biological images in class and the characteristics that become different in the image when this i

20. Proposal of signal constellations for the genetic code / Proposta de constelações de sinais para o codigo genetico
A proposta deste trabalho é apresentar uma abordagem aos processos genéticos e moleculares, utilizando a teoria de comunicações e codificação na modelagem do dogma central da biologia molecular. A partir desta modelagem associamos o código genético a um modulador de um sistema de comunicação. Mais especificamente, tal procedimento consiste em const

21. Algumas controvérsias sobre a origem da vida
In the present paper some controversies on the origin of life are discussed. Did the first living beings on Earth have an autotrophic or heterotrophic origin? What did come first, genetic code or metabolism? Were cells invented early? What was the role of minerals regarding the origin of life?

22. The mitochondrial genome of the stingless bee Melipona bicolor (Hymenoptera, Apidae, Meliponini): sequence, gene organization and a unique tRNA translocation event conserved across the tribe Meliponini
At present a complete mtDNA sequence has been reported for only two hymenopterans, the Old World honey bee, Apis mellifera and the sawfly Perga condei. Among the bee group, the tribe Meliponini (stingless bees) has some distinction due to its Pantropical distribution, great number of species and large importance as main pollinators in several ecosystems, inc

23. Aspectos clinicos da deglutição, da fonoarticulação e suas correlações geneticas na Doença de Machado Joseph / Clinical aspects of swallowing, voice/speech and genetic correlation in Machado Joseph disease
Introduction: Machado-Joseph (MJO) is a degenerative, autosomal dominant inherited disease, common to populations of Portuguese descent. It is a form of triplet repeat genetic disorder. The original mutation is caused by an abnormal repetition of the CAG code on chromosome 14q. The estimated prevalence in Brazil is 1: 1 00,000. The polymorphic symptoms appea

24. Propriedades bioquímicas e cinético-enzimáticas de cisteíno- proteases do intestino médio da lagarta da soja / Biochemistry and kinectics-enzymatics properties of cysteine-proteases of the velvetbean caterpillar midgut
Protease inhibitors that react with insect specific proteases are candidates to have their genetic code inserted in genetically modified plants. The first step to achieve this is the characterization of proteolytic enzymes of these insects intestines. Cysteine-protease of the soluble and insoluble fractions from the midgut of Anticarsia gemmatalis were chara
