  • Control de un sistema de energía basado en volantes de inercia para mitigar los huecos de tensión en el punto de conexión común
    Publication . Uguña, Carlos Orellana; Morales, Luis González; Sousa, Nuno
    Este artículo presenta el diseño de un sistema de energía basado en volante de inercia para mitigar los huecos de tensión. Con el sistema se mejora la calidad de energía en un punto de una red de distribución, el cual está expuesto a la conexión aleatoria de máquinas eléctricas. Para ello, se modela el sistema de distribución de energía, el sistema de inyección de energía que está compuesto por una máquina eléctrica con volante de inercia, el sistema de conversión de energía bidireccional y el sistema de control de corriente, voltaje y velocidad. El sistema diseñado permite inyectar una potencia de 22.8 kW y capacidad de 1.2 Wh, compensando los transitorios producidos por las cargas conectadas a la red.

  • Nurses’ Role in the Control and Treatment of Asthma in Adults: A Systematic Literature Review
    Publication . Alexandre-Sousa, Pedro; Sousa, Nuno; Bento, Joana; Azevedo, Filipa; Assis, Maíra; Mendes, José
    Bronchial asthma is a chronic pathology and a global public health problem. However, asthma can be controlled and treated for the most part by patients, so the Portuguese General Directorate of Health recommends shared medical appointments in primary health care (PHC). The present study aims to identify the role of PHC nurses in the control and treatment of asthma in adults. Using the MeSH platform, the following descriptors were validated: asthma, nurses, adults. An individual search was carried out in the following databases: CINAHL (ESBSCO host), MEDLINE (Pubmed host), Web of Science, and Scopus. Out of a total of 280 publications, 79 of which were duplicates and 185 publications which did not meet the inclusion criteria, 16 publications remained readable. Of the eligible articles, there were 13 specialist reports, one mixed study, one quasi-experimental study, and one randomized trial. Education was the intervention most identified in the scientific evidence analyzed, and patient assessment, application of an asthma control questionnaire, verification and training of inhalation technique, empowerment for self-management of the disease, support, promotion of seasonal influenza vaccination, and use of written action plans were also identified. The results reveal that, although the scientific evidence on the intervention of these professionals is poorly developed, nurses play a crucial role in the control and treatment of asthma. The scientific evidence analyzed allowed the identification of interventions that can help the organization of a nursing health appointment, providing nurses with a crucial role in the control and treatment of asthma in adults in the context of PHC.
