Cervical cancer is a public health problem, being the fourth most common type of tumor among women worldwide and the third most common cancer among women in Brazil. It is known that cervical cancer is one of the most easily preventable forms of cancer, as there is a highly effective vaccine against HPV, however, morbidity and mortality rates related to human papillomavirus are still frightening, especially in less developed countries. Low vaccination adherence rates, especially the second dose, are probably a reflection of the lack of knowledge about this virus, its clinical repercussions, and the vaccine. A clinical trial was carried out in a higher education institution in Alagoas (Brazil), with students of the medical course to whom a validated questionnaire was applied on HPV in the virtual environment (google forms). Data collection was carried out throughout the month of May of the year 2023. It was shown that the knowledge of medical students about the human papillomavirus was less than what would be desired for future doctors. The alert for the acute need to assess health illiteracy is clear, especially regarding cancer that can be prevented by a highly effective vaccine.展开更多

The simulations were performed in PSCAD with actual Brazilian system data. Specifically the following studies were performed: electromagnetic transient studies of energization maneuver considering no fault and the occurrence of fault along the trunk;dynamic analysis of generator units that will energize the AC-Link;TRV on the circuit-breaker that will energize the trunk. The main conclusion is that the AC-Link energization experiment can be implemented without jeopardizing or causing time-life reduction of the equipment involved in the experiment, which comprises the generator unit that will energize the trunk, the step-up transformer, the arresters that will be kept during the experiments, as well as the circuit-breaker that will energize and then trip the AC-Link.展开更多
