Resumo Cesário Verde, poeta português do século XIX faleceu aos 31 anos por tuberculose. A sua curta vida foi dividida entre a atividade poetica, mal reconhecida em vida, e a atividade comercial. Este trabalho procura refletir acerca do papel que a doença representou no seu percurso poético, a difícil relação com a Medicina e, finalmente, na importância que a relação médico-doente pode assumir.

Abstract Cesário Verde, a Portuguese poet of the 19th century, died at the age of 31 from tuberculosis. His short life was divided between poetic activity, barely recognized in life, and commercial activity. This work seeks to reflect on the role that the disease played in its poetic journey, the difficult relationship with Medicine and, finally, the importance that the doctor-patient relationship can assume.

Abstract Blends of zein and poly(vinyl alcohol) (PVAl) were processed in an internal mixer (150ºC, 50 rpm) for 5-8 minutes. Glycerol and oleic acid were used as plasticizers. The mixtures obtained were then compression molded and further characterized by Fourier transform infrared spectroscopy (FTIR), water-absorption experiments, mechanical tests, and scanning electron microscopy (SEM). FTIR analysis indicated the existence of hydrogen bonding interactions between zein and PVAl. Tensile tests showed that the addition of PVAl increased the flexibility of the blends. The tensile strength ranged from 1.7 to 5.7 MPa, elongation at break ranged from 2.7 to 32% and Young’s modulus ranged from 433 to 7371 MPa. Water absorption at equilibrium decreased with increasing zein content, which favored a brittle behavior in the zein/PVAl. The blends were immiscible in the composition studied and the presence of voids indicated poor interfacial interaction between the polymers.

Nos últimos anos a introdução crescente de tecnologia tem alterado a prática médica, com o risco de menor interação com o doente. Neste contexto, alguns autores defendem que o ensino médico deverá incidir na narrativa da história de vida, como forma de melhorar a compreensão do doente e aumentar a empatia. O autor defende que a anamnese, instrumento básico da prática médica, deve incluir a colheita da narrativa de vida, mantendo o doente no centro da atividade clínica.

In recent years the increasing introduction of technology has changed medical practice, with the risk of less interaction with the patient. In this context, some authors argue that medical education should focus on narrative-based practices as a way to improve the patient´s understanding and increase empathy. The author argues that anamnesis, the basic instrument of medical practice, must include the collection of the life narrative, keeping the patient at the center of clinical activity.

This paper presents the results of a study that aimed to monitor and evaluate biodegradation in soil, by the mass loss and the mechanical properties of plastic tubes. For this work, there were extruded and injected plastic tubes made of biodegradable polymer poly(hydroxybutyrate) - (PHB) and composite PHB/Wood Flour and PHB/Sisal Fiber, both with 20% fiber. There were used three biodegradation test devices for 30, 60 and 90 days. At the end of each test, the biodegraded samples were taken from soil, washed thoroughly with water, dried and weighed to evaluate the mass loss. Mechanical properties were evaluated using flexural tests before and after biodegradation in soil. Based on the results, it was observed that all the studied tubes lost mass over the biodegradation test, and the tubes of biodegradable composites lost more weight than pure PHB.

This study focuses on the interactions between economic agents, verifying the assumption that innovation and competitiveness in an industry are systemic, with relatively diffuse sources, which co-evolve. In this sense, were used the approach of the Sectoral Innovation System defined by Malerba (2002), analyzing the relationship between three dimensions of analysis: organizations, institutions and technologies. The object of this study was the Industry of Sugar and Ethanol in Alagoas, the largest producer and exporter of sugar and ethanol in the Northeast of Brazil. The results indicated a positive interaction between those three dimensions of analysis; show that there is interaction between universities and research centers, and much of the technological advancement comes from public and private partnerships. It is noteworthy that the research effort focuses on genetic improvement and on innovations of process. Thus, the study indicates that there is an innovation system locally circumscribed.

Este trabalho apresenta os resultados do comportamento de blendas do polímero biodegradável PHB poli(hidroxibutirato) com os copoliésteres também biodegradáveis EastarBio® e Ecoflex®, na composição de 75% de PHB e 25% dos copoliésteres, em contato com solo composto simulado. Foi também avaliada a influência da adição de pó de serra ou farinha de madeira, na proporção de 70% da blenda e 30% de pó de serra (p.d.s.). A biodegradação foi avaliada para amostras após 30, 60 e 90 dias em contato com solo, através de análises gravimétricas, morfológicas e mecânicas. A preparação inicial dos grânulos dos compostos poliméricos foi feita por extrusão, utilizando uma extrusora dupla-rosca e a moldagem dos corpos de prova foi realizada através da moldagem por injeção. Os materiais estudados biodegradam nas condições testadas. A blenda PHB/EastarBio® (75/25) + 30% p.d.s. apresentou maior redução de massa, 29% após 90 dias. Notou-se que a biodegradação se inicia pela superfície do material e que 90 dias são insuficientes para observar alterações internas.

This paper reports on blends made with the biodegradable polymers poly(hydroxybutyrate) (PHB) and Eastar Bio® or Ecoflex® copolyesters, in contact with simulated compound soil. The blends had 75% of PHB and 25% of copolyesters. We also analyzed the influence from adding 30% of powder-wood or wood flour (WPC) to 70% of the blend. Biodegradation was analyzed for samples after 30, 60 and 90 days in contact with soil, through thermogravimetric, morphological and mechanical analyses. The initial preparation of the granules of polymeric compounds was made by extrusion, using a twin-screw extruder and the molding of the specimens was performed by injection molding. The analysis indicated material biodegradation under the conditions tested. The PHB/Eastar Bio® blend (75/25) + 30% WPC exhibited the highest degradation with 29% of mass loss at the end of 90 days. Biodegradation started on the material surface and 90 days were not sufficient to induce noticeable internal changes.

Foram estudadas as propriedades térmicas e mecânicas de compósitos de polipropileno, virgem e reciclado, reforçados com 30% em massa de fibras residuais de sisal, assim como o perfil de processamento e a morfologia da matriz polimérica. Para tanto, foram determinadas a resistência à tração, o módulo de Young, alongamento na ruptura, e energia de impacto. As amostras também foram caracterizadas por MEV, DMTA e TG. Para ambos os compósitos de polipropileno, virgem e reciclado, com a adição das fibras, o alongamento na ruptura mostrou uma queda significativa, enquanto que a resistência à tração não sofreu grandes variações. Houve um aumento significativo nos valores de tração na ruptura e de energia de impacto com a adição das fibras de sisal na matriz de polipropileno. As análises térmicas mostraram ligações secundárias, como as ligações polares, entre as fibras e a matriz, concordando com o comportamento mecânico dos compósitos. Constatou-se que a temperatura de transição vítrea não variou após a adição da fibra.

The mechanical and thermal properties of virgin and recycled polypropylene composites reinforced with 30% by mass of residual sisal fibers were studied, in addition to an analysis of the extrusion process and morphology of the polymeric matrix. Tensile strength, Young's modulus, elongation at break, and impact energy were determined. The samples were also characterized by SEM, DMTA and TG analyses. Elongation at break of the composites presented a significant decrease, while the tensile strength was not affected significantly by addition of sisal fibers. A significant increase was observed in the tension of rupture and in the impact energy of the composite reinforced with sisal fiber. The thermal analyses indicated secondary interactions, such as polar interactions, between the fibers and the matrix, consistent with the mechanical behavior of the composites. The glass transition temperature has not changed after fiber addition.
