Spatial variability of chemical attributes in soils tends to increase under the no-tillage system. However, data regarding this variability under this system for a long time are scarce. This study aimed to evaluate the spatial variability of phosphorus (P), organic matter (OM), pH, aluminum (Al), calcium (Ca), magnesium (Mg), potassium (K), base saturation (V%), sulfur (SO42-), and micronutrients: boron (B), ir...
The objectives of this study were to evaluate the serum biochemical profile in Quarter Horse mares in their peripartum, and neonates on their birth date, and to compare the values obtained for male and female foals, as well as values obtained for foals and mares on the day of delivery. Forty one adult, pregnant mares and their respective offspring on the day of delivery were analyzed, totaling 82 animals. Two s...
O presente trabalho foi dirigido no sentido de realizar uma análise descritiva da precipitação pluviométrica mensal de estações climatológicas do Estado do Rio de Janeiro, utilizando medidas de posição e de dispersão e análises gráficas, e, através de um estudo sobre a aplicação de modelos de séries temporais, verificar a presença das componentes de sazonalidade e de tendência nestes dados. Os dados experimenta...
