1. Ultrasound reference values for the calcaneus of children and adolescents at moderate altitudes in Peru
Abstract Objective: a) Establish reference values for bone parameters by using the speed of sound (SOS, m/s) of broadband ultrasound attenuation (BUA, dB/MHz) and establish a bone quality index (BQI = αSOS + βBUA) for children and adolescents living in a region of moderate altitude, b) compare bone parameters with an international standard (with different

2. Impact of particle size, thermal processing, fat inclusion, and moisture addition on starch gelatinization of broiler feeds
The present study evaluated the effect of feed particle size, thermal processing different levels of fat inclusion and of moisture addition on the amount of gelatinized starch in a corn-soybean broiler diet. The different processing factors were combined in a 2 x 4 x 4 x 2 factorial arrangement in a three randomized block design consisting of three productio

3. Diagnose nutricional e potencial de resposta a adubação em cana-de-açúcar (Saccharum spp.) na região de Tabuleiros Costeiros em Alagoas.
An experiment was carried out in the region of Coruripe, Alagoas, aiming to establish DRIS norms for the diagnosis nutritional status of sugarcane, calculate the nutrient indexes by the DRIS method, utilizing four criteria in order to obtain the norms: C1 nutrient relations with the highest variance ratio, C2 nutrient relations with the highest variation rat

4. Zero-inflated Poisson regression models for QTL mapping applied to tick-resistance in a Gyr x Holstein F2 population
Nowadays, an important and interesting alternative in the control of tick-infestation in cattle is to select resistant animals, and identify the respective quantitative trait loci (QTLs) and DNA markers, for posterior use in breeding programs. The number of ticks/animal is characterized as a discrete-counting trait, which could potentially follow Poisson dis

5. Ensaios em economia da saúde : o risco e o valor de uma vida estatística no caso dos acidentes de trânsito na cidade de Porto Alegre
Nesta tese são desenvolvidos três estudos sobre o risco associado aos acidentes de trânsito, com o objetivo de avaliar como a população o percebe, e o valor que estaria disposta a pagar para reduzi-lo. As análises foram feitas com duas diferentes metodologias econométricas e dois diferentes conjuntos de dados da população de Porto Alegre. O primeiro

6. TRANSFORMAÇÃO DE DADOS COM EXCESSO DE ZERO EM EXPERIMENTOS COM CULTURAS OLERÍCOLAS / TRANSFORMATION OF DATA WITH EXCESS OF ZERO VALUES INTO OLERICULTURE EXPERIMENTS
Em olericultura, o interesse maior é a produção de frutos comercializáveis. Nesses experimentos comumente são avaliadas variáveis como fitomassa e número de frutos. No entanto, essas variáveis apresentam uma característica particular que está relacionada com sua ausência ou presença, no momento da colheita. Este atributo está representado pela o

7. Uma análise bayesiana para dados composicionais.
Compositional data are given by vectors of positive numbers with sum equals to one. These kinds of data are common in many applications, as in geology, biology, economy among many others. In this paper, we introduce a Bayesian analysis for compositional data considering additive log-ratio (ALR) and Box-Cox transformations assuming a mul- tivariate normal dis

8. Modelagem para detecção de talentos desportivos em jodocas.
Our objective was to create statistical models to avaluate the classification probability in the judo players of the juvenile category in the Championships of Pernambucano (local), North-Northeast (regional), Brazilian (national) and South American (international). The data were supplied by the Center of Sporting Excellency (CENESP) located in the University
