1. Stevia rebaudiana (Bert) Bertoni: regression models with mixed effects for investigating seed germination data
ABSTRACT. We investigated regression models with mixed effects using generalized linear statistics to evaluate germination data from Stevia rebaudiana (Bert) Bertoni. Estimates and validation of statistical parameters were conducted using the “gamlss” package in the R software. Generalized linear mixed effects followed the binomial, the beta-binomial and

2. A new model for describing remission times: the generalized beta-generated Lindley distribution
New generators are required to define wider distributions for modeling real data in survival analysis. To that end we introduce the four-parameter generalized beta-generated Lindley distribution. It has explicit expressions for the ordinary and incomplete moments, mean deviations, generating and quantile functions. We propose a maximum likelihood procedure t

3. ESTIMATE OF REFERENCE EVAPOTRANSPIRATION THROUGH CONTINUOUS PROBABILITY MODELLING
ABSTRACT This study aimed at testing the fit of continuous probability distributions to a daily reference evapotranspiration dataset (ET0) at a 75% probability level for designing of irrigation systems. Reference evapotranspiration was estimated by the Penman-Monteith method (FAO-56-PM) for eight locations, within the state of Espírito Santo (Brazil), where

4. Parameter induction in continuous univariate distributions: Well-established G families
The art of parameter(s) induction to the baseline distribution has received a great deal of attention in recent years. The induction of one or more additional shape parameter(s) to the baseline distribution makes the distribution more flexible especially for studying the tail properties. This parameter(s) induction also proved helpful in improving the goodne

5. Estudo de expansões assintóticas, avaliação numérica de momentos das distribuições beta generalizadas, aplicações em modelos de regressão e análise discriminante
Inicialmente, realiza-se uma revisão literária sobre as expansões assintóticas de Daniels, Edgeworth, Lugannani-Rice e Cordeiro-Ferrari. Mediante uso da expansão de Cordeiro- Ferrari, torna-se possível realizar um estudo correspondente a aproximação da distribuição gama G(m;f ) em função da distribuição exponencial com média a. E, ainda, numa

6. Equação de estimação generalizada e influência local para modelos de regressão beta com medidas repetidas / Generalized estimating equation and local influence to beta regression models with repeated measures
Utilizando a teoria de função de estimação linear ótima (Crowder, 1987), propomos equações de estimação generalizadas para modelos de regressão beta (Ferrari e Cribari-Neto, 2004) com medidas repetidas. Além disso, apresentamos equações de estimação generalizadas para modelos de regressão simplex baseadas nas propostas de Song e Tan (2000) e

7. Ecologia de Florestas Atlânticas com ocorrência do muriqui (Brachyteles spp.): diversidade, sucessão secundária e estrutura nutricional / Atlantic Forests ecology holding muriqui (Brachyteles spp.): diversity, secondary succession and nutritional structure
This study has three chapters which mainly aimed the understanding on the role of forests variables affecting distribution, abundance and range ecology of primates belonging to Brachyteles genera. The first chapter specifically aimed on characterization and comparisons of tree species diversity and secondary succession among three forests holding Brachyteles

8. Core histone hyperacetylation co-maps with generalized DNase I sensitivity in the chicken beta-globin chromosomal domain.
The distribution of core histone acetylation across the chicken beta-globin locus has been mapped in 15 day chicken embryo erythrocytes by immunoprecipitation of mononucleosomes with an antibody recognizing acetylated histones, followed by hybridization probing at several points in the locus. A continuum of acetylation was observed, covering both genes and i

9. Search for the optimal sequence of the ribosome binding site by random oligonucleotide-directed mutagenesis.
Synthetic DNA duplexes corresponding to the ribosome binding site (RBS) were synthesized through the phosphite method on solid support. The synthetic RBS DNA with partial random sequences was inserted into an appropriate site between the lpp-lac promoter and the beta-galactosidase structural gene in plasmid pMKT2. The level of beta-galactosidase expression w

10. A homozygous mutation in the integrin alpha6 gene in junctional epidermolysis bullosa with pyloric atresia.
The alpha6 integrin subunit participates in the formation of both alpha6beta1 and alpha6beta4 laminin receptors, which have been reported to play an important role in cell adhesion and migration and in morphogenesis. In squamous epithelia, the alpha6beta4 heterodimer is the crucial component for the assembly and stability of hemidesmosomes. These anchoring s
