Abstract: eight crosses among oat lines were evaluated aiming to estimate heritability and to verify the effect of selection for plant height and heading date. four f2 panicles from each cross were harvested in 1993. each one generated one line of spaced plants in the field in the following year. the f3 plants were individually evaluated and separated in classes based on mean population and standard deviation. the same traits were evaluated in 1995 in plots representing the different classes. heritability was estimated by parent x offspring regression method. difference among classes was an indicator of selection efficiency. heritability estimates varied from -0,73 to 0,84 for plant height and from 0,25 to 1,05 for heading date. difference among classes was generally associated with high values of heritability. the heritability of the traits was high, indicating feasibility of selection in segregant generations. the conversion of data in standard deviation units allowed a reduction of genotype x environment interaction, leading to more precise estimates.

Abstract: Oito popula es provenientes de cruzamentos entre linhagens de aveia foram avaliadas com o objetivo de estimar a herdabilidade e verificar o efeito da sele o para estatura de planta e dura o do ciclo vegetativo. Quatro panículas F2 por cruzamento foram colhidas em 1993, cada uma delas originando uma linha de plantas espa adas no ano seguinte. As plantas F3 foram avaliadas individualmente e classes foram estabelecidas com base na média e desvio padr o da popula o. Os mesmos caracteres foram avaliados em 1995, em parcelas representando as classes selecionadas. A herdabilidade foi estimada pelo método da regress o pai x progênie. A diferen a entre classes foi testada como um indicador da eficiência da sele o. As estimativas de herdabilidade variaram de -0,73 a 0,84 para estatura e de 0,25 a 1,05 para ciclo vegetativo, estando a diferen a entre classes, em geral, associada a valores elevados de herdabilidade. A herdabilidade para os caracteres estatura de planta e dura o do ciclo vegetativo para algumas popula es foi alta, evidenciando a viabilidade da sele o em gera es precoces. A transforma o de dados em unidades de desvio padr o permitiu a redu o dos efeitos da intera o genótipo x ambiente, levando a uma maior precis o das estimativas obtidas.

Geomaterials (GM) , 2013, DOI: 10.4236/gm.2013.32007
Abstract:

The aim of this work was to study the use of coal waste to produce concrete paving blocks. The methodology considered the following steps: sampling of a coal mining waste; gravity separation of the fraction with specific gravity between 2.4 and 2.8; comminution of the material and particle size analysis; technological characterization of the material and the production of concrete paving blocks. The results showed that the coal waste considered in this work can be used to replace conventional sand as a fine aggregate for concrete paving blocks. This practice can collaborate in a cleaner coal production.
