1. Dificuldades orçamentárias básicas das famílias brasileiras: um convite à reflexão a partir de redes bayesianas / Basic budgetary difficulties of Brazilian families: an invitation to reasoning from bayesian networks
Este estudo visa compreender a adequação dos rendimentos às necessidades e condições de vida dos brasileiros. Observando os dados da Pesquisa de Orçamentos Familiares (POF) realizada pelo IBGE (Instituto Brasileiro de Geografia e Estatística) para o período: 2008 e 2009, o estudo identifica um modelo que se concentra na investigação sobre o fato de

2. Estudo do modelo de famÃlias de distribuiÃÃes de probabilidade baseado em programaÃÃo matemÃtica
Since immemorial times, man has learned to deal with uncertainty in trying to prevent losses derived from unexpected factors. Several probability theories were proposed in such a search, KolmogorovÅs having been the most used. However, it fails to serve a number of situations. A great deal has been done in order to work out the situations where the classic

3. Desempenho de populações segregantes de algodoeiro obtidas por três métodos de hibridação
CHAPTER I - The objectives of this research were to make predictions on segregant populations performance on upland cotton as for selection, using the method proposed by Jinks and Pooni (1976), as well as to identify amongst three different crossing methods, which will originate the most promising population for selection purposes. The present work was condu

5. Fenologia e chuva de sementes em Floresta Estacional Semidecidual no município de Viçosa, Minas Gerais, Brasil. / Phenology and seed rain in Semidecidual Seasonal Forest in Viçosa, Minas Gerais, Brazil
The present study was divided in two chapters. On the first it was aimed to study the phenology of 20 arboreal species and to answer the following questions: (1) Which is the seasonality degree in the production of flowers, fruits, falling and leaf shooting? (2) Are there any flowering and fructification synchrony intra and interespecific? (3) What is the in

6. O Evangelho segundo a Pastoral da Criança :por uma pedagogia da sobrevivência
This work aims to analyze social and educational actions at Pastoral da Criança, using education as a survival tool. This was done at Parque dos Coqueiros, a neighborhood in Natal, Rio Grande do Norte. The methodology for data collection was composed of comprehensive interview (Jean Kaufmann), participant observation (Robert Bogdan) and documental analysis

7. Using gene carrier probability to select high risk families for identifying germline mutations in breast cancer susceptibility genes.
Germline mutations in highly penetrant autosomal dominant genes explain about 5% of all breast cancer, and heritable mutations in the BRCA1 breast and ovarian cancer susceptibility gene account for 2-3% of breast cancer in the general population. Nevertheless, the presence of such mutations is highly predictive of disease development. Since screening for mut

8. Origin of the additional chromosome in Down's syndrome: a study of 20 families.
In 20 families with a Down's syndrome child, heteromorphism of chromosome 21 was sought in the parents and proband. Information on the meiotic division and the parent of origin was given in 16 families, the majority of errors being maternal in origin, predominantly at meiosis I, though the paternal contribution is also appreciable. Probabilities of parental

9. X linked or autosomal recessive? A new approach to an old problem.
Families in which a single male is affected with a disease which might be either X linked recessive or autosomal recessive present problems in counselling. Before female relatives can be counselled, the probabilities of each mode of inheritance must be assessed, taking into account the prior probabilities, the pedigree structure, any DNA probe data, and any

10. Evolution of multigene families under interchromosomal gene conversion.
A model for the evolution of the probabilities of genetic identity within and between loci of a multigene family in a finite population is formulated and investigated. Unbiased interchromosomal gene conversion, equal crossing-over between tandemly repeated genes, random genetic drift, and mutation to new alleles are incorporated. Generations are discrete and

11. Gene Conversion, Linkage, and the Evolution of Multigene Families
The evolution of the probabilities of genetic identity within and between the loci of a multigene family is investigated. Unbiased gene conversion, equal crossing over, random genetic drift, and mutation to new alleles are incorporated. Generations are discrete and nonoverlapping; the diploid, monoecious population mates at random. The linkage map is arbitra

12. The application of linkage analysis to genetic counselling in families with Duchenne or Becker muscular dystrophy.
A total of 278 families of probands with Duchenne or Becker muscular dystrophy has been ascertained and offered genetic counselling. Linkage studies have been performed in these families using polymorphic DNA markers identifying loci linked to Duchenne and Becker muscular dystrophy. The clinical features of the probands are discussed: there was marked intraf
