TL;DR: In this article, a contribuicao dos mecanismos de fluxo de massa e de difusao for o suprimento de potassio, de calcio e de magnesio a plantas de arroz, em experimento realizado em casa de vegetacao.
Abstract: O transporte de nutriente ate a superficie das raizes pode ocorrer por fluxo de massa ou por fluxo de massa e difusao, dependendo da atividade do nutriente na solucao do solo e da exigencia nutricional da planta. Objetivou-se verificar a contribuicao dos mecanismos de fluxo de massa e de difusao para o suprimento de potassio, de calcio e de magnesio a plantas de arroz, em experimento realizado em casa de vegetacao. Aplicaram-se em amostra de Latossolo Variacao Una, os seguintes tratamentos: Na2CO3, K2CO3, CaCO3 e MgCO3. Aos 75 dias da semeadura, as plantas de arroz foram colhidas e determinadas as quantidades de potassio, de calcio e de magnesio nelas acumuladas, bem como a concentracao desses nutrientes na solucao do solo. Essas concentracoes, multiplicadas pelo volume de agua transpirado, foram usadas para calcular o suprimento por fluxo de massa. A difusao foi estimada por diferenca entre a quantidade do nutriente acumulado no vegetal e a transportada por fluxo de massa. Verificou-se que o potassio foi transportado predominantemente por difusao, exceto no tratamento com K2CO3, que gerou altos teores de K na solucao de solo, tornando o fluxo de massa suficiente para atender a demanda das plantas. O calcio e o magnesio foram transportados por fluxo de massa. Segundo os resultados, a difusao foi o principal mecanismo de transporte de potassio nas condicoes do experimento; todavia, o fluxo de massa pode satisfazer isoladamente a demanda nutricional da planta, quando a concentracao de potassio na solucao do solo for muito elevada.

TL;DR: An accelerated solvent extraction procedure for use with gas chromatography-mass spectrometry (GC-MS) was optimized for the determination of eight polycyclic aromatic hydrocarbons (PAHs) in cocoa beans and only one sample was found to have a PAH content above the maximum limit defined by the European Union legislation.

TL;DR: Evaluated chicken meat affected by wooden breast (WB) myopathy in the production of chicken sausages presented higher values for pH, L*, moisture, cooking loss, shear force, hardness, chewiness, adhesiveness and gumminess; while WHC and protein content were higher for N chicken meat.
Abstract: The aim of this study was to evaluate the suitability of using chicken meat affected by wooden breast (WB) myopathy in the production of chicken sausages. Compare the technological and sensory properties of such sausages were compared with those produced from normal (N) breast meat. Three types of chicken sausages were elaborated: 100% containing N chicken meat, 100% of WB chicken meat and 50% N/50% of WB meat. The WB chicken meat presented higher values for pH, L*, moisture, cooking loss, shear force, hardness, chewiness, adhesiveness and gumminess; while WHC and protein content were higher for N chicken meat. N and WB chicken sausages presented similar values of WHC, a*, b* color values, protein content and TBARS. QDA indicated no sensory differences between the three sausage formulations, so did the acceptability and purchase intention. Therefore, WB chicken meat may be used to produce chicken sausages combined or not with N chicken meat. Further studies, however, may be required to investigate the nutritional value and digestibility of WB meat and derived products.
