Current societal challenges increasingly demand the need to seek for efficient and sustainable solutions to daily problems. Construction, as a result of its activity, is one of the main responsible industry for the exploitation of resources and greenhouse gas emissions. In this way, several research works are being undertaken to change some of the current practices. This paper presents the work being done at University of Minho to study de degradation of natural fibers when used as a sustainable solution for soil reinforcement. Jute and sisal fibrous structures (0º/90º) were studied in terms of their degradation over time, when incorporated into soil and when subject to accelerated aging tests in a QUV weathering test equipment. Results show that the process of biodegradation of natural fibers is clearly accelerated by the action of temperature, moisture and solar radiation, explaining further degradation of jute and sisal fibers when exposed to these factors, although more pronounced in jute fabric structures.

Procurou-se contribuir para esboçar uma problemática de pesquisa em torno da privatização em educação, no quadro das relações entre o Estado e os domínios público e privado e tomando como horizonte a construção do direito fundamental à educação e do bem-estar social, situados no Portugal democrático. Argumentou-se que o Estado e as políticas públicas têm, nestes 40 anos, desempenhado um papel central naqueles processos. Durante muito tempo, com fases e combinações distintas, pode observar-se uma espécie de duplicidade na ação estatal, com o acento tónico ora na expansão e consolidação do sistema público, ora no apoio e sustentação de atores e dinâmicas de ampliação do espaço e da influência privados, às vezes assumindo simultaneamente uma e outra orientação em setores diferenciados. Sugere-se, no entanto, que, desde 2011, no quadro de políticas regressivas austeritárias de ajustamento estrutural, com origem na União Europeia, se assistiu a uma rutura em favor de um projeto societal neoliberal radical que, a ser bem sucedido, procura instituir um sistema educativo pobre para pobres e alterar o estatuto e o papel do direito à educação e do sistema público que constitucionalmente o realiza.

OBJECTIVE: To evaluate the use of thrombolytic and acetylsalicylic acid therapies in acute myocardial infarct patients as well as the availability of technical and human resources for the care of these patients in the emergency units of the city of Rio de Janeiro. Additional objectives were the evaluation of the use of primary angioplasty and the level of acceptance of SBC /RJ as an entity responsible for programs of continued medical education. METHODS: Interviews with physicians at 46 emergency units in the city of Rio de Janeiro. RESULTS: Of the 46 emergency units inspected, a policy of encouragement to use thrombolytic therapy was only prescribed in 6.5%. In 1/3 of the public wards no thrombolytic agents were available, and in none of them was access to primary angioplasty regularly available; 45.9% did not offer the minimal conditions required for the handling of cases of acute myocardial infarction; 60% of the physicians on-call (at both public and private emergency units), appeared not to know the importance of the use of acetylsalicylic acid in acute myocardial infarct patients; all physicians interviewed would participate in programs of continued medical education organized by the SBC/RJ. CONCLUSION: The study suggests there was: 1) the low probability of the use of thrombolytic therapy in the majority of the emergency units in of the city of Rio de Janeiro due to the inadequate policy of waiting for the transfer of the patient to coronary or intensive care unit; 2) a low awareness to the importance of early use of acetylsalic acid in acute myocardial infarct; 3) half of the emergency units of the public net do not have the minimal conditions required for the handling of cases of acute myocardial infarction; 4) a high level of credibility exists that would enable the SBC/RJ to set up programs for continued medical education to change the mentality regarding the use of thrombolytic therapy and of acetylsalicylic acid.

OBJECTIVE: To investigate the effects of receptive music therapy in clinical practice. METHODS: Receptive music therapy was individually applied via musical auditions, including five stages: musical stimulation, sensation, situation, reflection, and behavioral alteration. Following anamnesis and obtainment of consent, patients answered a first questionnaire on health risk evaluation (Q1), and after participating in 16 weekly music therapy sessions, answered a second one (Q2). RESULTS: Two men and 8 women, aged above 18 years, referred to us due to symptoms of stress, emotional suffering, and the need to change lifestyles (health risk behavior) were studied between August 1998 and December 1999. Comparison between answers to Q1 and Q2, showed a trend (P=0.059) for reduction of ingestion of cholesterol-rich foods and for increased prospects in life with a tendency towards improvement, and also of increased intake of fiber-rich food (55.6%), increased levels of personal satisfaction (44.5%), and decreased levels of stress (66.7%). CONCLUSION: The study demonstrated decreased stress levels and increased personal satisfaction, higher consumption of fiber-rich food, lower cholesterol intake, and a better perspective on life, suggesting that receptive music therapy may be applied in clinical practice as an auxiliary therapeutic intervention for the treatment of behavioral health risks.
