This study defines a model to predict the erosivity of the Pantanal Biome correlating the calculated rainfall erosivity index EI 30 and the rainfall coefficient (Rc). The model showed a significant correlation with the observed data, yielding coefficient of determination of 97%. Therefore, the rainfall erosivity model proposed can be used to estimate the R Factor of USLE data from monthly and annual precipitation for the region and other regions with similar climatic characteristics.

The water resources management in Brazil is affected by the lack of hydrological information, which can be filled by hydrological models that simulate the behavior of watersheds. However, it was noticed that many models do not generate good results when performed outside of the study area where they were created. Therefore, due to its adaptability, the J2000 model linked into the Jena Adaptable Modelling System (JAMS) framework was evaluated for simulating two basins at the outcrop zone of the Guarani Aquifer System, the Ribeirão da Onça

RESUMO O objetivo do presente estudo foi avaliar a qualidade da analgesia proporcionada pela morfina e meperidina em gatos acometidos por processos traumáticos e submetidos Palavras-chave: gatos, analgesia, opióides. SUMMARYThe purpose of this study was to evaluate the quality of analgesia provided by morphine and meperidine in the cats presenting traumatic process and submitted to osteosynthesis, Eighteen animals were divided into two groups. Animals from group I were premedicated with acepromazine (0.2mg/kg) and meperidine (4.0mg/kg) and were induced with administration of ketamine (3.0mg/kg) and midazolan (0.3mg/kg). Anesthesia was mantained using halothane and 100 % oxigen. Group II was premedicated with acepromazine (0.2mg/kg)
