1. Genetic diversity of long-established populations of Elaeis guineensis jacquin (Arecaceae)
Resumo Este trabalho objetivou estimar a diversidade genética de três populações de Elaeis guineensis no Estado do Rio Grande do Norte, bem como verificar a diminuição do tamanho efetivo da população. A população com maior polimorfismo foi a MAT (Mata), com 57 locos (72%), seguida pela RIA (Riacho), com 54 locos (68%), e HOR (Horta), com 34 locos

2. Assessing the reliability of predictive activity coefficient models for molecules consisting of several functional groups
Currently, the most successful predictive models for activity coefficients are those based on functional groups such as UNIFAC. In contrast, these models require a large amount of experimental data for the determination of their parameter matrix. A more recent alternative is the models based on COSMO, for which only a small set of universal parameters must b

4. Genetic diversity in natural populations of Jacaranda decurrens Cham. determined using RAPD and AFLP markers
Jacaranda decurrens (Bignoniaceae) is an endemic species of the Cerrado with validated antitumoral activity. The genetic diversity of six populations of J. decurrens located in the State of São Paulo was determined in this study by using molecular markers for randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP).

5. POLITOPOS DE GOSSET E OS GRUPOS DE COXETER E(N) / GOSSET POLYTOPES AND THE COXETER GROUPS E(N)
A convex polytope is semiregular if all its faces are regular and the group of isometries acts transitively over vertices. The classification of semiregular polytopes includes a few infinite families, some low dimensional exceptions and a family, the Gosset polytopes, which is defined for dimension 3 to 8. Certain groups of isometries of R(n) generated by re

6. Actions of groups on sphere product, cohomology of virtually cyclic groups (ZaX| Zb)X| Z and [ZaX|(ZbXQ2i)]X|Z and Tate Cohomology / Ações de p-grupos sobre produto de esferas, co-homologia dos grupos virtualmente cíclicos (Z IND.aX| Z IND. b)X| Z e [Z IND.aX| (Z IND.bX Q IND.2 POT. i)] X| Z e cohomologia de Tate
In this work is studied the rank of the fixed point set of a semifree action on spaces X~p S POT.nX S POT.nand X~p S POT.nX S POT.nX S POT.n, with n>0. We also consider the extension of the result for actions of p-groups on spaces X~p SPOT.nX S POT.m, with 0

7. O tornar-se o que se é do professor de matemática e o espaço escolar
This work was conducted from interviews with teachers of mathematics education of the public network of Juiz de Fora (MG) and its proposal to understand the formation of the teacher on their experiences in school. In other words, show your "become what it is" a perspective that is based on the thought of the German philosopher Friedrich Nietzsche. The sense

8. Development of an external electroosmotic flow control system for capillary electrophoresis with contactless conductivity detection / Elaboração de um sistema de controle externo do fluxo eletrosmótico para eletroforese capilar com detecção condutométrica sem contato
This work presents the implementation, in an equipment for capillary electrophoresis (CE) with contactless conductivity detection (C4D), of a system for external control of the electroosmotic flow (EOF) via external radial voltage (Vrad). Through external potential, directly applied to the capillary, the electroosmotic flow can be controlled, because this pr

9. Uso de marcadores microssatélites para avaliação genética de populações de Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) no Estado da Bahia / Microssatellites markers applied to genetic evaluation of populations of Melipona mandacaia Smith, 1863 (Hymenoptera, Apoidea) in Bahia State, Brazil
Melipona mandacaia, is an indigenous stingless bee (Meliponini Tribe), an endemic species of the semi-arid of the northeast of Brazil. The original flora of the caatinga has been altered by the human action. This alteration reduces the food resources and the places available for nesting, so this affects the dispersion and the genetic flow of the populations

10. Grupos pseudo-livres, primos seguros e criptografia RSA
When a cryptographic scheme is defined over a group, encrypting messages is equivalent to assigning values in this group to variables of some equation, whereas breaking this scheme is âto discoverâ which values were assigned to those variables. Therefore, the security of such schemes is connected to the hardness to solve equations over groups. The use of f

11. RELATIONSHIP MARKETING APLLIED IN COOPERATION NETWORK: THE CASES OF MANIA SUL NETWORK AND CONSTRUMAIS NETWORK / MARKETING DE RELACIONAMENTO APLICADO A REDES DE COOPERAÇÃO: OS CASOS MANIA SUL E CONSTRUMAIS
In the present study, relationship marketing actions have been approached from the symbiosis of the models described by Vavra (1993) and Souza (1997) in two groups of small retail sale companies together in a cooperation net. The nets Construmais and Mania Sul", which work as a construction material store and a supermarket store, respectively, have been stud

12. Central polynomials for graded algebras / Polinomios centrais para algebras graduadas
In this thesis we study graded central polynomials and central polynomials with involution for some important algebras in the theory of algebras with polynomial identities, over infinite fields. Namely we describe the Z2-graded central polynomials for the algebras M2(K) (the 2 x 2 matrices over the field K), Ml,1(5), where 5 is an arbitrary supercommutative
