1. Genetic gains in agronomic and technological traits of elite cotton genotypes
ABSTRACT The objective of this work was to estimate the predicted genetic gains with the simultaneous selection of agronomic and technological traits from elite cotton lines using selection indexes. Data from the evaluation of 36 elite lines were evaluated in three trials located in Apodi-RN in 2013 and 2014 and Santa Helena, GO, Brazil in 2013, in a randomi

2. Heartwood and sapwood in eucalyptus trees: non-conventional approach to wood quality
ABSTRACT This study evaluated the quality of heartwood and sapwood from mature trees of three species of Eucalyptus, by means of the qualification of their proportion, determination of basic and apparent density using non-destructive attenuation of gamma radiation technique and calculation of the density uniformity index. Six trees of each species (Eucalyptu

3. Swingle citrumelo seed vigor and storability associated with fruit maturity classes based on RGB parameters
ABSTRACT: Citrus seeds normally have low storability. Identifying an optimal fruit harvest time for production of high vigor seeds is important for nurseries; however, identifying this stage for Swingle citrumelo fruits has been based only on visual color examination, and research related to this parameter has been inconsistent. The main objective of this st

5. Uso do inventário florestal como ferramenta de monitoramento da qualidade silvicultura em povoamentos clonais de Eucalyptus / Using the forest inventory as a tool of monitoring silvicultural quality in Eucalyptus clonal plantations
A produtividade florestal é definida pelo ambiente de produção em que o povoamento está inserido, pela implantação de materiais genéticos superiores e pelo seu correto manejo silvicultural. A correta prescrição de recomendações silviculturais e a execução das operações de maneira padronizada tem por objetivo eliminar ou minimizar as restriçõ

6. CARACTERIZAÇÃO FLORÍSTICA, DIVERSIDADE E CORRELAÇÃO AMBIENTAL NA FLORESTA NACIONAL DE SÃO FRANCISCO DE PAULA, RS / FLORISTIC CHARACTERIZATION, DIVERSITY AND ENVIRONMENTAL CORRELATION IN THE NATIONAL FOREST OF SÃO FRANCISCO DE PAULA, RS
Populations and species are disappearing due to disturbances in the environment caused by human activities. Given the obvious risk of loss of diversity, it is increasingly necessary to take actions concerning preservation, in which safety features are necessary for measuring the variation of diversity in space and time. The aim of this study was to evaluate

7. Reliability based calibration of partial safety factors of brazilian design codes / Aplicação de confiabilidade na calibração de coeficientes parciais de segurança de normas brasileiras de projeto estrutural
This study addresses the partial safety factors used in structural design codes. The study is based on the theory of structural reliability, which allows an explicit consideration of the uncertainties in material strengths and load actions, and results in a quantitative measure of structural safety: the reliability index. A calibration methodology is conside

8. Diversity among populations goats based on morphometric markers / Diversidade genética entre populações caprinas com base em marcadores morfométricos
The goats were introduced in Brazil by the Portuguese colonizers. Today it is difficult to accurately identify the origin of the Brazilian domestic animals and it is unknown the entire extent of its diversity. The conservation and breeding of domestic animals depend on diversity in the species concerned. Theobjectives of this study were 1. compare different

9. IrrigaÃÃo e fertirrigaÃÃo em um sistema de aspersÃo convencional submetido à tÃcnicas de controle estatÃstico de qualidade. / Irrigation and fertigation in sprinkler system submitted to techniques of statistical quality control
The contribution of irrigation in the alimentary supply, is due to the fact of more and more to look for more efficient systems, monitoring the indexes of uniformity of distribution of the water. The application of fertilizers through irrigation water took very big pulse in the last times, mainly due to the emergence of pressurized systems, of the tunnels of

10. Biodiversidade e abundância da ictiofauna associada ao cultivo orgânico de Litopenaeus vannamei (Boone, 1931)
The expansion of shrimp farming has caused a series of environmental impacts, often as a result of lack of planning and adequate management. Organic aquaculture has emerged as an alternative to conventional shrimp farming, and differently, aims at the economical, ecological and farming potential of other organisms, such as fishes, oysters and seaweeds. The p
