1. Plot size for evaluation of Arabica coffee yield
ABSTRACT. In most cases, in genetic breeding of Arabica coffee, plot size is defined in an empirical manner. It is often based only on the experience of the breeders and the availability of resources, potentially leading to a reduction in precision. Therefore, the aim of this study was to estimate the size of the experimental plot for evaluation of coffee yi

2. Métodos alternativos para estimar tamanho ótimo de parcelas experimentais: uma aplicação na cultura da bananeira / Alternative methods for estimating the optimum size of experimental plots: an application in banana
Unidade experimental, ou parcela, é a unidade que recebe a aplicação do tratamento e fornece os dados que deverão refletir o seu efeito. O tamanho ótimo de parcela experimental está diretamente relacionado com a precisão do experimento, uma vez que o tamanho apropriado reduz o erro experimental. Este trabalho teve como objetivos utilizar os métodos M

3. Analise da adaptabilidade por regressao segmentada com estimacao da juncao dos segmentos.
Os metodos que relacionam as respostas individuais de genotipos com o indice de ambiente por meio de equacoes de regressao lineares simples nao sao capazes de identificar o genotipo desejavel, ou seja, o genotipo responsivo a ambientes favoraveis ou melhorados e que mantenha produtividade razoavel em ambientes adversos. O metodo de regressao linear segmentad

4. Controle operacional otimizado de sistemas de canais / Optimized operational control of systems of canals
This work presents a hydraulical model of control of otimização of systems of canals, constituted in three stretches, linked for 4 floodgates, where each stretch is segmented in 17 we. It is used theory of the regulator linear quadratic (RLQ), with the purpose to lead the system to the balance condition, exactly that it has variations and/or disturbances i

5. Models for the analysis of growth curves for rearing tinamous (Rhynchotus rufescens) in captivity
Growth curves models provide a visual assessment of growth as a function of time, and prediction body weight at a specific age. This study aimed at estimating tinamous growth curve using different models, and at verifying their goodness of fit. A total number 11,639 weight records from 411 birds, being 6,671 from females and 3,095 from males, was analyzed. T

6. Aplicação orientada a objetos para análise físicamente não-linear com modelos reticulados de seções transversais compostas
This masters thesis refers to the computational implementation, according to objectoriented paradigm, of material nonlinear solution of finite element models of framed structures with composed and geometrically arbitrary cross sections. These sections are represented by decomposition in smaller areas, in which the materials nonlinear stress-strain relations

7. The expectation of consumer and its influence on sensory perception and acceptance of coffee / A expectativa do consumidor e sua influencia na aceitação e percepção sensorial de cafe soluvel
In products such as instant coffee, which require preparation before consumption, the expectations of the consumer may be influenced by the sensory stimuli emanating from the product during the manipulation and gradual contact occurring during the preparation process. On the other hand, sensory analysis still lacks research studying the validation of statist

8. Timing of peak bone mass in Caucasian females and its implication for the prevention of osteoporosis. Inference from a cross-sectional model.
To determine the timing of peak bone mass and density, we conducted a cross-sectional study of bone mass measurements in 265 premenopausal Caucasian females, aged 8-50 yr. Bone mass and bone mineral density were measured using dual X-ray absorptiometry and single-photon absorptiometry at the spine (anteroposterior, lateral), proximal femur, radius shaft, dis

9. Comparative impacts of two major hurricane seasons on the Neuse River and western Pamlico Sound ecosystems
Ecosystem-level impacts of two hurricane seasons were compared several years after the storms in the largest lagoonal estuary in the U.S., the Albemarle–Pamlico Estuarine System. A segmented linear regression flow model was developed to compare mass-water transport and nutrient loadings to a major artery, the Neuse River Estuary (NRE), and to estimate mean
