Influência do tipo de lignina na caracterização de compósitos poliméricos com fibra natural

The use of recycled raw materials and renewable sources are necessary for economical, social, environmental and technological development. In this context, this work aims to study the influence of two lignin types, one derived from pine (Lig I) and the other one from eucalyptus, (Lig II) on polymer composites properties of recycled low density polyethylene (r-LDPE-Al) and Pinus Elliotti wood flour (WF), in the proportion 70% and 30% matrix/reinforcement in weight, respectively. The r-LDPE-Al is from Tetra Pak post-consumer packaging. The composites were processed by extrusion in a laboratory co-rotation twin-screw extruder. The composites obtained were evaluated through tests of melt flow index (MFI), tensile strength, Charpy impact strength, density and heat deflection temperature (HDT). The MFI results indicated that both lignin showed potential use as a flow agent for r-LDPE-AL/WF composites, with an increase of 41% and 13% for Lig I and Lig II, respectively, when compared with composite reference 0 (without lignin). Mechanical test results showed that the lignin origin influences the composites’ properties where Lig I, is derived from pine (the same source as wood flour) had the best performance, indicating a potential use as a coupling agent. The results were favorable for a more noble reuse for post-consumer packaging and the lignin by-product.O uso de matérias-primas recicladas e de fontes renováveis faz-se necessário tanto para o desenvolvimento econômico, social, ambiental quanto tecnológico. Nesse sentido, esse trabalho consiste no estudo da influência de 2 tipos de ligninas (uma derivada de pinus e denominada como Lig I e outra de eucalipto, denominada Lig II) na caracterização de compósitos poliméricos com polietileno de baixa densidade reciclado (r-PEBD-Al) e farinha de madeira (FM), da espécie Pinus Elliotti, na proporção 70% e 30% em massa de matriz/reforço, respectivamente. O r-PEBD-Al é oriundo das embalagens pós-consumo Longa vida. Os compósitos foram processados em extrusora de laboratório dupla rosca co-rotante. Os compósitos obtidos foram avaliados através dos ensaios de índice de fluidez (IF), tração, resistência ao impacto Charpy, densidade e temperatura de deflexão térmica (HDT). Os resultados de IF indicaram que ambas as ligninas apresentaram potencial uso como agente de fluxo para os compósitos de r-PEBD-Al/FM, com 41% e 13% de aumento para Lig I e Lig II, respectivamente, em relação ao compósito 0 sem lignina (referência). As propriedades mecânicas evidenciaram que a origem da lignina influencia no desempenho dos compósitos, sendo que a Lig I, que é derivada de pinus, mesma fonte que a farinha de madeira apresentou uso potencial como agente de acoplamento. Os resultados se mostraram favoráveis para um reaproveitamento mais nobre para as embalagens pós-consumo e o subproduto lignina

O impacto da esquizofrenia para a família

The impact of schizophrenia on the family has been compared to the trauma experienced by victims of catastrophes. Considering the social repercussion on the health system and the emotional repercussion on the schizophrenic individual, with consequences to the family group, an ethnographic case study was developed aimed at describing the impact of schizophrenia on the family. One family consisted of father, mother, and five children, four of whom are schizophrenic, participated in the study, and have had a follow-up in a public psychiatric service. Schizophrenia impacts family members through their suffering, isolation, and overloadEl impacto de la esquizofrenia en la familia ha sido comparado con el trauma vivido por las victimas de una catástrofe. Considerando las repercusiones sociales en el sistema de salud y el impacto emocional para el individuo esquizofrénico que incide en el grupo familiar, se desarrolló un estudio de tipo etnográfico cuyo objetivo fue describir el impacto de la esquizofrenia en la familia. Participó en este estudio un grupo familiar compuesto por padre, madre y cinco hijos, de los que cuatro son portadores de esquizofrenia y están en control en un servicio psiquiátrico comunitario.

A Clear Cell Sarcoma Case: A Diagnostic and Treatment Challenge, with a Promising Response to Trabectedin

Clear cell sarcoma; Radiotherapy; TrabectedinSarcoma de cèl·lules clares; Radioteràpia; TrabectedinaSarcoma de células claras; Radioterapia; TrabectedinaIntroduction: Clear cell sarcoma (CCS) is a rare and aggressive soft tissue sarcoma. CCS is characterized by the translocation t(12;22) (q13;q12), involving the fusion of EWSR1 and ATF1 genes, and less frequently the fusion gene EWSR1-CREB1. Usually, CCSs are considered poorly responsive to conventional chemotherapy. However, trabectedin has shown activity against translocation-related sarcomas. Furthermore, preclinical results suggest that trabectedin is a promising antitumor agent for CCS, potentially inducing melanocytic differentiation. Case Presentation: We report the case of a challenging anatomopathological diagnosis in a patient with an aggressive metastatic CCS. Following the diagnosis of CCS, the patient experienced a clinical and radiological tumor response to trabectedin after four lines of treatment. Conclusion: This is a novel report of CCS treated with trabectedin that resulted in a partial response and suggests the need for further research on trabectedin as a therapeutic option for CCS.This research was funded by PharmaMar, S.A

Citizenship against the Pelli-Cajasol skyscraper in Seville

Esta comunicación narra la historia de una derrota de la sociedad civil preocupada por su patrimonio cultural y sus paisajes históricos urbanos. Se trata de la trayectoria de la Plataforma Ciudadana ¡Túmbala! y del Manifiesto contra la Torre Pelli-Cajasol, organizaciones de asociaciones, colectivos, personas y profesionales de diferente perfil y procedencia que desde principios del año 2009 se oponen al rascacielos de 178 metros de altura que promueve Cajasol, ahora Caixabank, en el extremo sur de la Isla de la Cartuja de Sevilla, en la denominada Puerta Triana de acceso a la Exposición Universal de 1992. El edificio, en su fase final y a punto de inaugurarse, ha roto definitivamente el perfil histórico de Sevilla, imponiendo su presencia de forma hegemónica sobre la ciudad. El camino recorrido supone la lucha de la ciudadanía por participar de las decisiones que le afectan de forma directa, como pueden ser aquellas relativas a qué es y cómo se protege su patrimonio histórico y al simbolismo que contienen determinados espacios y paisajes urbanos, ya que conforman una parte del derecho a la ciudad de todos sus habitantes. Tal lucha, infructuosa habida cuenta del resultado, se detalla a lo largo del texto, que a su vez ilustra la brecha abierta entre las instituciones públicas en todas sus escalas y la sociedad civil, así como la dominación efectiva ejercida por el poder económico y financiero de la banca.This work tells the story of a defeat by the civil society that tries to protect its cultural heritage and its historic urban landscapes.
