Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term

This work evaluates the existing potential in the state of Sao Paulo for the generation of electrical energy using the sugar cane bagasse as fuel. As the bagasse is a by-product of the sugarcane and alcohol industry and it is produced in large scale in the country, mainly in the state of Sao Paulo, it is important to develop researches that aim the best utilization of this input. In order to determine its potential, at first, a study was conducted considering the utilization of the cogeneration, which is a common practice in the plants of the sector. However, it was concluded that the cogeneration could provide a higher quantity of energy if more modern technologies and more efficient processes were used. Another study to estimate the potential considered a system of gasification of the sugar cane bagasse integrated with the combined cycle (BIG/GTCC). It was concluded that this technology can provide a considerable increase in the electrical supply. In this work it was also developed an energetic study based on real data from a plant located in the state of Sao Paulo. A thermodynamic analysis was done in the existing equipment of the cogeneration section of the plant. And another analysis was done considering the implementation of the BIG/GTCC technology to the cogeneration system. Comparing the results of both settings, it was concluded that the utilization of the sugar cane bagasse integrated to a combined cycle increased considerably the efficiency in the generation of electricity of the plant, increasing more than six times its production capacity of electrical energy

FUNDAMENTO: Na hipertensão arterial pulmonar (HAP) a qualidade de vida relacionada saúde (QVRS) tem sido investigada em curtos períodos de tempo (semanas), mas pouco se sabe sobre a perspectiva do paciente no médio e longo prazo. OBJETIVO: Analisar o estado de pacientes em terapias específicas de HAP durante um ano de observação, em termos de QVRS, e investigar se possíveis associações entre a capacidade de exercício (CE) e a QVRS persistem no médio prazo. MÉTODOS: Trinta e quatro pacientes em terapias para a HAP (bosentan e/ou sildenafil) foram selecionados (idade de 14 a 58 anos, mediana de 35,5 anos, classe funcional II ou III), e avaliados no momento basal, e 3, 6, 9 e 12 meses depois, usando o teste de caminhada de 6 minutos e questionário SF-36 de QVRS. RESULTADOS: A distância percorrida nos seis minutos não mudou durante o acompanhamento (387 - 432 metros, valores da mediana, p=0.2775), o mesmo para a classe funcional e saturação periférica de oxigênio. Os escores SF-36 também se mantiveram estáveis, com a saúde física sempre pior que a saúde mental. Das 40 possíveis associações entre a CE e QVRS, apenas 12 foram significativas (30%, p<0,05). A previsão de uma QVRS severamente deprimida com base em uma distância percorrida de 235 metros foi específica em >90%, mas sensível em <43%. CONCLUSÃO: Os pacientes com HAP que se mantêm estáveis em termos da CE também parecem fazê-lo em termos de QVRS. Contudo, CE e QVRS não têm ligação consistente com o tempo, e devem ser analisadas como diferentes perspectivas no paciente individual.
