1. Quantifying individual variation in reaction norms using random regression models fitted through Legendre polynomials: application in eucalyptus breeding
ABSTRACT An accurate, efficient and informative statistical method for analyses of genotype × environment (G × E) interactions is a key requirement for progress in any breeding program. Thus, the objective of this study was to quantify individual variation in reaction norms using random regression models fitted through Legendre polynomials in eucalyptus (E

2. Reaction norms models in the adjusted weight at 550 days of age for Polled Nellore cattle in Northeast Brazil
The objective of this study was to evaluate the genotype-environment interaction (GEI) in the body weight adjusted to 550 days of age (W550) of Polled Nellore cattle raised in Northeastern Brazil using reaction norms (RN) models. Hierarchical RN models included fixed effects for age of cow (linear and quadratic) and random effects for contemporary groups (CG

3. Sensibilidade de valores genéticos às modificações de níveis de proteína das dietas e avaliação de carcaça de codornas de corte em crescimento / Sensibility of genetic values to modifications of diet protein levels and the evaluation of meat quail carcass in growth
The objective of this study was to investigate the presence of genotype X dietary protein level, by reaction norm models, on the period of growth and evaluate the performance of two strains of quails belonging to Breeding Program Poultry of the Federal University of Viçosa. Body weights were evaluated at 21, 35 and 42 days of age, with levels 24 to 33% crud

4. Estudo numérico da aplicação do método dos elementos finitos de Galerkin e dos mínimos quadrados na solução da equação da convecção-difusão-reação tridimensional / Numerical study of the application of Galerkin and least squares finite element methods in the solution of the tridimentional convection-diffusion-reaction equation
This paper the application of the Finite Element Method in variants Galerkin and Least Squares with auxiliary equations for the numerical solution of partial differential equation that models the convection-diffusion-reaction defined over a three-dimensional domain in steady state. In the spatial discretization were used hexahedrons elements with eight (line

5. Interação genótipo x ambiente via correlações genéticas entre rebanhos e normas de reação utilizando abordagem bayesiana em bovinos de corte / Genotype by environment interaction using genetic correlations between herds and reaction norms under bayesian approach in beef cattle
O presente estudo teve por objetivo estudar os efeitos da interação genótipo x ambiente sobre as características peso à desmama, peso ao sobreano e ganho de peso da desmama ao sobreano em bovinos da raça Nelore. Foram analisados 58.032 registros de peso à desmama ajustados para 205 dias (PD), 46.032 registros de peso ao sobreano ajustados para 550 dia

6. Modelos de normas de reação para estudo da interação genótipo x ambiente / Reaction norms models for study of genotype by environment interaction
O objetivo desse estudo foi avaliar diferentes modelos estatísticos com diferentes pressuposições para definir o melhor modelo que descreva a presença de interação genótipo x ambiente no ganho de peso pós-desmama ajustado (GPD345) de bovinos Hereford, mediante o estudo de normas de reação ao ambiente, obtidas por regressão aleatória, usando uma a

7. The manual motor ability evaluation of children between five and six years from two São Paulo schools / Avaliação da habilidade motora manual em crianças de cinco e seis anos de duas escolas paulistanas
The shortage of normative data in instruments and specific tests for the Brazilian population is a challenge to the professionals that intend to measure the effectiveness of its work. At the practical clinic, many diagnoses, preventions and treatments are established with the use of tests or measuring instruments. Instruments and tests that cover the motor d

8. Desenvolvimento de objetos de aprendizagem para o ensino de geoprocessamento. / Development of the learning objects to geoprocessing learning.
The information and communication technologies hold expressive potential for educational environments. The usage of these technologies can make viable the transformation of a presence course to a distance course or simply utilizes these like support to presence courses. The learning objects are defined alike any entity, digital or not digital, that can be us

9. Contribution to Crushed Stone Petrography / Contribuição à petrografia de pedra britada
It is extremely important to know the physical and chemical properties of aggregate mineralogical composition so that the construction where they will be used is not compromised. In this sense, knowing the petrography and mineralogy is as necessary as knowing the geology of the rock deposit to be developed as a source of crushed stone. The main purpose of th

11. Phenotypic plasticity of Myzus persicae (Hemíptera: Aphididae) raised on Brassica oleracea L. var. acephala (kale) and Raphanus sativus L. (radish)
The study of variability generated by phenotypic plasticity is crucial for predicting evolutionary patterns in insect-plant systems. Given sufficient variation for plasticity, host race formation can be favored and maintained, even simpatrically. The plasticity of size and performance (assessed by the lifetime fitness index r m) of six clones of Myzus persic

12. Reaction norms with bifurcations shaped by evolution.
Two versions of a model for the evolution of seasonal polyphenism investigate the evolution of reaction norm bifurcation and branching. The first version is without a specific submodel for morphological development and the second has an explicit developmental map. Version 1 is evolutionarily relatively unconstrained: (i) reaction norms are specified by matri
