26. Is the Eggshell Quality Influenced by the Egg Weight or the Breeder Age?
ABSTRACT For a long time, it has been said that eggshell quality decreases as eggs increase in size, but this increase is seen as the breeder age advances. Therefore, the present study aimed to evaluate the age and egg weight effect on Cobb 500 broiler breeders on eggshell quality. The quality measures tested were eggshell and mineral matter percentage, eggs

27. Reliability analysis of built concrete dam
Resumo O projeto convencional de barragens de gravidade de concreto ainda segue o método determinístico, que não quantifica diretamente o efeito das incertezas na segurança da estrutura. A teoria de confiabilidade estrutural permite a quantificação da segurança destas estruturas, a partir da quantificação das incertezas inerentes aos parâmetros de

28. The use of X-ray to evaluate Brachiaria brizantha seeds quality during seed processing
RESUMO O teste de raios X permite a visualização das estruturas internas das sementes de modo não destrutivo e individualizado, possibilitando o diagnóstico de causas da baixa germinação e pureza de um lote. O objetivo do trabalho foi avaliar a qualidade das sementes de Brachiaria brizantha utilizando-se o teste de raios X e o efeito das etapas de bene

29. HPGR as alternative to fused alumina comminution route: an assessment of circuit simplification potential
Abstract A considerable portion of energy consumption and, as a consequence, operational costs in mineral processing, is associated with comminution. High Pressure Grinding Rolls (HPGR) are appealing for their energy efficiency and resulting lower operating costs. This article evaluates this technology as an alternative to the conventional fused alumina comm

32. Egg quality of laying hens fed diets with plant extracts
ABSTRACT. The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was

33. INCIDENCE OF FUNGI IN MOMBASA GRASS SEEDS DURING THE STAGES OF THE SEED CONDITIONING PROCESS
ABSTRACT The objective of this study was to evaluate the effect of the seed conditioning process on the sanitary quality of Panicum maximum ‘Mombasa’ seeds. The seeds were sampled before processing and after exiting the seed blower and sieves (discharge from the top and bottom sieves), first gravity separator (intermediate discharge), seed treatment equi

34. A NEW PERSPECTIVE FOR PHYSICAL HEIGHTS IN BRAZIL
Resumo A definição das altitudes físicas proposta por Helmert em 1890 é um dos sistemas de altitude comumente utilizado na prática. Na definição de Helmert o valor médio da gravidade ao longo do fio de prumo é calculado simplificando a topografia, com Bouguer Shell, contendo um valor médio para a densidade de massas. Embora esta aproximação possa

35. BEAK TRIMMING BY INFRARED RADIATION OF LAYERS
ABSTRACT This study aimed at evaluating beak-trimming methods and intensities on the performance, beak length and uniformity, and egg parameters of commercial layers. During the rearing period, birds were distributed in randomized blocks, with a 2x3 factorial design + two treatments, consisting of beak trimming with infrared (IR) radiation (moderate or sever

36. Salt structures from inversion of residual gravity anomalies: application in Santos Basin, Brazil
Abstract The Santos Basin, with an area of about 350.000 km 2 , is the largest salt basin of the South Atlantic, and due to its high economic hydrocarbon potential, it is a recurrent theme in scientific studies. The salt structures over the region present great importance for hydrocarbon accumulation and the geological/geophysical studies are performed from
