Abstract Background The Regional Internship (RI) is an extension project provided by the Federal University of Santa Maria (Brazil) that gives the medicine students a real experience of how the Primary Health Care (PHC) works, offering them a chance to grow as professionals, gaining self-trust and autonomy while being supervised by the preceptors. The cities where the program operates are small and they suffer with lack of high-quality healthcare professionals, which makes this internship also important for these communities. Worldwide, mainly in developing countries, the deficiency of proper PHC is a problem that can be attenuated by this proposal of introducing updated doctors eager to improve their skills and benefit the society. Objective The aim of the present study is to report, through the interns' exposition, how the internship was capable of contributing for the life and formation of the medicine student. Results Based on an extension project that gives the students an opportunity of a more embracing experience with the community, it is possible to notice the importance of the extension on the curricular complementation. Moreover, with the interaction between students and community, the knowledge exchange and the experience with different cultures benefit and contribute to the medical formation of these students, as well as in the population health context. Conclusions This is a part of the portfolio delivered by an academic: 'At the end of the two months of Regional Internship I have the sensation of mission accomplished and satisfaction. The experience offered by this phase of the course is incomparable, I feel more secure, more autonomous, it's like the growth that was in a constant acceleration before now suffered an exponential improve.' Key messages The benefits of Regional Internship cannot be evaluated only by quantitative indicators, but also by the individual experiences lived by interns, preceptors and a general community. After the internship period, academics conclude that they feel more confident and encouraged to face the challenges of medical life.

Since many rotor systems normally operate above their critical speeds, the problem of accelerating the machine through its critical speeds without excessive vibration draws increasing attention. This paper provides an analytical imbalance response of the Jeffcott rotor under constant acceleration. The response consists of three parts: transient vibration due to the initial condition of the rotor, “synchronous” vibration, and suddenly occurring vibration at the damped natural frequency. This solution provides physical insight to the vibration of the rotor during acceleration.
