Wooden cellular slabs with and without insulation submitted to fire conditions

The wooden cellular slabs are lightweight structures, easy to assemble, and with excellent architectural features, as thermal and acoustic conditions. The wooden cellular slabs with perforations are typical and very common engineering solutions, used in the ceiling or flooring plates to improve the acoustic absorption of compartments, and also have a good insulation and relevant architectonic characteristics. However, the high vulnerability of wooden elements submitted to fire conditions requires the evaluation of its structural behavior with accurately. The main objective of this work is to present a numerical model to assess the fire resistance of wooden cellular slabs with different perforations. Also the thermal behavior of the wooden slabs will be compared considering material insulation inside the cavities

Shopping malls and neoliberal trends in Southern European cities: Post-metropolitan challenges for urban planning policy

Whilst shopping malls have been explored at length by critical urban studies, there has been little exploration of their role in restructuring the practice of urban and spatial planning. This article uses the shopping mall as an object of study in the light of the neoliberal trends and post-metropolisation in Southern Europe, with the aim of exploring challenges for urban governance and planning practice and with a focus on the role of the ongoing economic crisis. A threefold exploratory framework – the ‘lost-in-time scenario’, the ‘messianic mall model’ and the ‘(im)mature planning explanation’ – is used to make sense of the local versions of shopping mall development in Lisbon (Portugal) and Palermo (Southern Italy). According to findings, we highlight the clash between the multi-scalar nature of shopping malls and the dominance of the municipal scale in regulatory planning frameworks, and the risk that shopping mall development (at least in Southern Europe) may replicate uneven development patterns, reproducing the pre-conditions of the crisis without helping to overcome it.

Arte urbano en el espacio expositivo : siglo XXI a través del análisis de seis modelos singulares

En la actualidad, museos y galerías de todo el mundo realizan exposiciones de un arte que tiene sus orígenes en el espacio urbano. El presente estudio muestra las estrategias posibles que tanto los artistas como las instituciones museológicas y comisarios han adoptado para mostrar el arte urbano en el espacio expositivo. Los objetivos son analizar a través de seis exposiciones llevadas a cabo en Europa, en el transcurso del siglo XXI, las características conceptuales, técnicas y formales para realizar una exposición de arte urbano, buscando la interconexión existente entre el lenguaje artístico propio de este arte y el lenguaje expositivo. Para ello se muestra un contexto histórico en el que se abordan los principales casos desarrollados a lo largo de la historia, orientado a crear una base a un movimiento que actualmente está en pleno auge. Se analiza también el papel adyacente del graffiti con el arte urbano, encontrando tanto grandes similitudes como diferencias, que han coexistido a lo largo de los años complementándose unas con otras, sea entre los artistas, en el espacio urbano y en el espacio expositivo. Bajo la emergencia de muestras de arte urbano en la actualidad, este estudio selecciona seis exposiciones que tuvieron lugar en instituciones europeas desde el 2008. La variedad entre ellas permite realizar un análisis rico en posibilidades, como en Street Art en la Tate Modern, una institución de gran relevancia a nivel internacional y con artistas referentes dentro del movimiento; en Banksy versus Bristol Museum, en la que el mediático y anónimo Banksy crea una muestra heterogénea; con Os Gêmeos en el Museu Berardo en Lisboa se presenta una exposición de uno de los grandes referentes del arte urbano en el mundo, o el Palais de Tokyo que presenta unos espacios propicios para la muestra de este tipo de arte bajo una serie de eventos desarrollados en una amplia línea temporal con una gran variedad de artistas; Lisboa, ciudad distinguida por su implicación con el arte urbano, presenta dos muestras importantes, una en la Fundação EDP-Museu da Electricidade con la figura emergente de Alexandre Farto, y otra en el MUDE con el significativo André Saraiva. Bajo la premisa de que todos estos artistas han desenvuelto o desenvuelven su trabajo en la calle, se estudia su relación con el lenguaje adaptado para el espacio expositivo. El objetivo desarrollado es la búsqueda de una esencia que permita sentir y apreciar el arte urbano en todos sus contenidos, sea formal, técnica o conceptualmente, reflexionando acerca de la naturaleza del mismo para así realizar la complicada descontextualización de presentar un arte en un espacio ajeno a sus raíces. Tras el análisis de las exposiciones, se observan varias formas de abordar la inclusión en el museo, categorizándolas en exposiciones individuales, colectivas, históricas y temáticas, creando cuatro líneas curatoriales. Desde la perspectiva de las estrategias creativas analizadas en las exposiciones, se observan diferentes recursos tanto por parte de los artistas como de las instituciones para introducir el arte urbano en el contexto museológico, encontrando aspectos que coexisten dentro y fuera del espacio expositivo. Además, el estudio examina cómo a lo largo de la historia hubo un intento de aproximación e inclusión del arte popular al espacio expositivo, lo cual desenvolvió un camino para la institución museológica actual, que debe defender un servicio y un compromiso con la sociedad bajo la actual demanda de un público interesado en el arte urbano

The effect of extreme cold temperatures on the risk of death in the two major Portuguese cities

It is well known that meteorological conditions influence the comfort and human health. Southern European countries, including Portugal, show the highest mortality rates during winter, but the effects of extreme cold temperatures in Portugal have never been estimated. The objective of this study was the estimation of the effect of extreme cold temperatures on the risk of death in Lisbon and Oporto, aiming the production of scientific evidence for the development of a real-time health warning system. Poisson regression models combined with distributed lag non-linear models were applied to assess the exposure-response relation and lag patterns of the association between minimum temperature and all-causes mortality and between minimum temperature and circulatory and respiratory system diseases mortality from 1992 to 2012, stratified by age, for the period from November to March. The analysis was adjusted for over dispersion and population size, for the confounding effect of influenza epidemics and controlled for long-term trend, seasonality and day of the week. Results showed that the effect of cold temperatures in mortality was not immediate, presenting a 1–2-day delay, reaching maximumincreased risk of death after 6–7 days and lasting up to 20–28 days. The overall effect was generally higher and more persistent in Lisbon than in Oporto, particularly for circulatory and respiratory mortality and for the elderly. Exposure to cold temperatures is an important public health problem for a relevant part of the Portuguese population, in particular in Lisbon.

As marcas culturais das festas populares no fotojornalismo dos periódicos Correio da Manhã e Tribuna do Norte

This research is about the cultural marks and meanings production on the popular culture context, in honor of Catholics Saints of June: Saint Antony; Saint John and Saint Peter (with celebrations in June 13th, 24th and 30th respectively). These marks are find on the newspapers’ photography of Tribuna do Norte (Natal, Rio Grande do Norte, Brazil) and Correio da Manhã (Lisbon, Portugal). All the photos were published in June 2012. The analysis has theory and methodology in Folkcommunication and in Sociocultural Photocatography. The investigation has focus in the meanings of these marks on the photojournalism about the popular parties and their practices. The study observes also a common view to report about popular culture, which has the influence of a hegemonic paradigm that considers itself the only true one.

La creación de valor en el museo y la sociomuseología

Los museos tienen normalmente mucha dificultad en justificar su existencia y en demostrar su valor real y su contribución al desarrollo de las comunidades a las que sirven. El coste del mantenimiento de un museo, después de inaugurado, nunca parece estar justificado para las tutelas y financiadores que lo promovieron. El museo, grande o pequeño, puede ser un elemento esencial en el desarrollo cultural del conjunto social, pero necesita tener una actividad que lo justifique y que su labor sea reconocida. Para contribuir con eficacia debe compartir con la comunidad su misión y sus actividades y para probar su valor debe tener sistemas de evaluación que permitan verificar si su labor de investigación y acción sobre el patrimonio, de promoción de la cultura y la ciudadanía y de colaboración con escuelas y asociaciones, reduce el fracaso escolar, aumenta la participación en la vida y cultura o contribuye a la cohesión social y a la formación de ciudadanos más responsables y solidarios. La Sociomuseología estudia estos campos de la actividad del museo, acompaña experiencias y propone soluciones a estas dificultades.

Ki-67 Proliferation Index in Gastric Cancer - Biologic Significance

Objectives/Introdution: Ki-67 protein has been used as an indicator of proliferation activity in tumor cells. In gastric cancer the prognostic value has not been fully understood. This study was designed to assess the biologic significance of Ki-67 proliferation index (PI) in gastric cancer. Material/Methods: Seventy-two patients with gastric cancer were evaluated. These patients underwent gastric resection, and the tumor tissue was stained immunohistochemically. Ki-67 PI was defined as the percentage of tumor cells positive for Ki-67. Ki-67 PI was correlated with clinicopathological characteristics and patient survival. Results: A low Ki-67 PI (less than or equal to 50%) was associated with poorly differentiated histology - diffuse type (p=0.009) and signet ring cells (p=0.004) - and younger age (p=0.022). A worse prognosis in patients with low Ki-67 PI was also found (a mean survival of 41.8 vs 63 months for high Ki-67 PI group), but not statistically significant (p=0.623, log rank test). Discussion/Conclusion: We found an inversely correlation between Ki-67 PI and histological differentiation grade. Patients in group with low Ki-67 PI are younger, with poorly differentiated histology and have a lower mean survival. Like other studies already suggested, we may have two different tumors phenotypes - highly invasive with low proliferative capability, and less invasive potential with higher proliferative ability. However, in this sample, no significant prognostic value was achieved between both.
