2. Simultaneous prestack seismic inversion in a carbonate reservoir
Abstract We applied a method of Simultaneous Prestack Seismic Inversion (SPSI) in a hydrocarbon field located in the Campos Basin, Brazil. The goal was to study the application of this method to Albian carbonate rocks of the Quissamã Formation. Based on what is found in nearby fields, this Formation potentially contains hydrocarbon accumulations that can be

5. Comparative study between the efficiency of the Mozzarella stretching and the holder pasteurization of milk in the inhibition of the Mycobacterium fortuitum and the Listeria monocytogenes experimentally inoculated into buffalo milk / Estudo comparativo entre a eficiência da filagem da Mozzarella e da pasteurização lenta do leite na inativação do Mycobacterium fortuitum e da Listeria monocytogenes experimentalmente inoculados no leite de búfala
Whole buffalo milk was experimentally contaminated with Mycobacterium fortuitum and Listeria monocytogenes. The quantitative analysis of the agents was made immediately before and after two thermal treatments: pasteurization (of milk) and stretching (of Mozzarella). In the analysis of the Listeria, methodology adapted for the attainment of the MPN was used,
