The annual vaccination campaign against rabies is the most effective prevention procedure for this disease in dogs and cats and hence for human protection also. However, in 2010 and 2011, this activity was interrupted in Brazil due to the occurrence of adverse events associated with vaccination. Even though cases of canine rabies have been decreasing in the last two decades, vigilance must be strengthened in order to maintain pet owners trust in the vaccines provided in public services. This study aimed to determine pet owners participation in the annual vaccination campaign carried out in Botucatu. During March and April 2012, the period before the 42nd campaign, 312 pet owners, dogs and cats, were interviewed. The homes were randomly drawn in blocks from different sectors of the city; all houses on the same block over the 120 km² of urban area participated in the sampling process. Statistical analysis was performed descriptively. The results showed that the owners main motivation to vaccinate their pets during the campaigns is rabies prevention (36%), followed by the proximity of the vaccination station to the house (20.7%), zero cost (10.9%), and the combination of all three factors (16.1%). When asked if they would take their animals back to be vaccinated in another campaign, 60.1% answered yes, 13.5% would go to a private clinic, 2.2% would not take because they do not trust the vaccine and 1.6% had not decided yet. We conclude that the respondents have realized how dangerous Rabies is, because even after the break period, they still utilized the vaccination campaign demonstrating confidence in its effectiveness, while knowing the campaign goals facilitates understanding and participation.

The presented work aimed to present the Modular Construction scenario, relating it to the fundamentals assumptions on the Modular Coordination Theory. The presentation of this theory, its historical development, its scope and tools, were conceived to further, show how the applicability on the conceptual and design phases is done. Also, studies cases are shown, in order to illustrate didactically how this process occurs. Basing on these studies, considerations are made about the use of modulation in projects in Brazil, at the expense of what happens on the international scenario, to highlight the importance of Modular Coordination for raising the standards of construction quality and rationality in the country

The machining process is so much important in the economic world. Many machining parameters have been studied to maximize results, in terms of cost and lifetime. (decrease of cutting tool wear, improved surface finish, among others). The objective of this study is to evaluate the wear of a ceramic tool in the machining of the aluminum alloy 6005 A. The analysis of the wear of the cutting tools is very important due to its big impact on the final finishing of the piece as a whole. The evaluation took place in two stages, first it was done a detailed study of the literature of the whole machining process, where the study of the formation and swarf classification were among the most important steps in this phase. The second step consisted in the machining of the piece of aluminum 6005 A with a ceramic cutting tool constituded of aluminum oxide and magnesium oxide with silicon carbide impregnation. The swarf generated in this process was then photographed with a Zeiss optical microscope and analyzed for its size and shape. Through this comparison it was concluded that the swarf are generated shear swarfs, shaped like a tangled, fragmented and arcs connected, thus classifying the material as medium difficulty machining. Through the image analysis tool it was concluded that the parameter of lower wear was the: Vc = 500m / min, f = 0.10mm / rev and ap = 0.5mm
