We collected 50 samples of curasow feces from the Scientific and Cultural Breeding Center in the city of Poços de Caldas. The samples were enriched in broth medium Tetrationato and Cystine-selenite and plated on Salmonella Shigella (SS), Mac Conkey (MC), endo-C (EC), Brilliant Green (VB) and Eosyn Methilen Blue EMB, remaining at 37 °C for 24h. Colonies suspected of Salmonella were inoculated in tubes containing Agar Triple Sugar Iron (TSI) and again incubated at 37 ºC for 24h. Tubes with characteristic growth were submitted to slide agglutination test with polyvalent somatic and flagellar serum. The medium SS, MC and VB were the most efficient for growing, and 36% of samples were positive for Salmonella spp. As birds are important reservoirs of Salmonella spp and it may represent a high risk to human health, there is a need to implement a cleaning routine in enclosures avoiding contamination between the enclosures and the consequent entrainment of these micro-organisms, by the keepers until their homes or other venues. The presence of Salmonella in breeding centers may be responsible for lower hatchability of eggs, undermining the purpose of the entity, which is to study and maintain the various birds species.

Procura-se nesse trabalho expor as considerações levantadas sobre a modularidade e a temporalidade do filme Pulp Fiction (1994), de Quentin Tarantino, enquadrada por Simons (2008) nas categorias de narrativa audiovisual complexa denominadas modular narratives e database narratives. Com Ricoeur (1983), discutiu-se a sua organização temporal a partir do conceito de tríplice presente em Santo Agostinho, enquanto com Propp (1970) e Cameron (2008) o cará- ter modular dessa narrativa.

The multiphase steels are gaining increasing attention in scientific studies because of the different mechanical and microstructural properties that the material can achieve under different thermomechanical and heat treatments that can be submitted. In the present study, it was made a microstructural study thru the triple attack technic associated with optical microscopy and mechanical characterization of medium carbon AISI 4350 steel thru a tensile strength test, subjected to three routes of heat treatment: annealing, quenching and tempering and isothermal annealing. It was verified the predominance of ferrite-perlite constituent in the specimen annealed, martensitic in the quenched and tempered specimen and bainitic in the annealed isothermally specimen. The annealed material showed a higher ductility, while the hardened and tempered specimen showed the highest hardness and ultimately the bainitic specimen showed a combination of the two abovementioned mechanical properties. Thus, we proved that the multiphase steel SAE 4350 can be a versatile material with great potential for various industrial applications
