3. Genetic parameters, genetic trends, and principal component analysis for productive and reproductive traits of Guzera beef cattle
ABSTRACT The objectives of this study were to estimate genetic parameters and genetic trends and perform principal component analysis for the following traits: body weight adjusted at 210 days of age (W210), one year (W365), and yearling or 450 days of age (W450); weight gain from birth to weaning or 210 days of age (WGBW), from weaning to 365 days of age (W

4. DNA and the displacement of certainties in brazilian family law
Resumo Enfocando o impacto da tecnologia do DNA no direito de família brasileiro, pela análise de leis, jurisprudência e processos particulares lidando com disputas de paternidade, mapeamos tendências de mudança ao longo dos últimos trinta anos. Mostramos como, após um momento de ceticismo inicial, a evidência genética parece dominar o cenário lega

5. Genetic evolution of milk yield, udder morphology and behavior in Gir dairy cattle
ABSTRACT The objective of this study was to analyze the genetic evolution of milk production, udder morphology, and animal behavior of Gir dairy cattle. Data were obtained on the predicted breeding values for milk yield of 60,226 cows born from 1968 to 2015 and standardized predicted breeding values for udder conformation and milking behavior of 7,635 cows b

6. Biochemical and Biological Properties of Soil from Murundus Wetlands Converted into Agricultural Systems
ABSTRACT The implementation of conservationist systems that improve soil properties and reduce the impacts of the conversion of native areas is fundamental for feasible agricultural exploitation. This study aimed to evaluate the impact on soil biological properties caused by the conversion of murundus fields into agricultural systems and verify the ability o

7. Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
ABSTRACT This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having different aspect ratio (d/h= 0.5, 1.0 and 2.0) were measured for various frictional conditions (m=0.1-0.4). The change in radii

9. Direct and maternal annual genetic changes for selected traits at weaning and yearling in beef cattle
ABSTRACT. Heritability and direct and maternal genetic changes were estimated in Nellore cattle for the following traits: birth to weaning weight gain (BWG), weaning to yearling weight gain (YWG), weaning conformation (WC), weaning precocity (WP), weaning muscling (WM), yearling conformation (YC), yearling precocity (YP), yearling muscling (YM) and yearling

10. Current trends of genetics in apical periodontitis research
Abstract: Genetics is an emerging topic in endodontic research focusing on the host response regarding the pathogenesis of apical periodontitis (AP). A number of genetic epidemiological studies carried out by many investigators worldwide have shown evidence of an association between certain candidate genes and AP. Some studies have been conducted on knockout

11. Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT strain tilapia (Oreochromis sp.) selected for weight gain. The data set used contained information on 6,650 animals. The genetic values of 8,5

12. Genetic structure of populations of Pissodes castaneus (De Geer) (Coleoptera, Curculionidae) using amplified fragment length polymorphism
Genetic structure of populations of Pissodes castaneus (De Geer) (Coleoptera, Curculionidae) using amplified fragment length polymorphism. The objective of this study was to determine the genetic structure of populations of Pissodes castaneus from different areas and on different species of Pinus using the PCR-AFLP technique. Twenty samples were analyzed, re
