Casas de renda económica : requalificação do edifício Tipo 9 da Série III do Bairro do Tarrafal na cidade de Guimarães

Mestrado Integrado em ArquitecturaExame público realizado em 12 de Julho de 2016A intuito da presente dissertação incidiu numa intervenção no Bairro do Tarrafal na cidade de Guimarães, um projecto replicado com os princípios do Bairro de Alvalade em Lisboa numa procura de requalificação de um modelo histórico em grande deterioração. Num primeiro momento torna-se fundamental entender o estado social e económico que o país vivia após a segunda guerra, assim como a influência que o regime ditatorial teve nas mentalidades e na arquitectura. Num segundo momento o enquadramento das habitações de âmbito económico e a sua relação com as necessidades da época, nunca esquecendo de caracterizar os princípios subjacentes destas Casas de Renda Económica, descrevendo o modelo base de forma clara para se compreender os princípios replicados por todo o país em contextos urbanísticos diferentes. Por fim uma reflexão à problemática do Bairro do Tarrafal e às necessidades da cidade de Guimarães de forma a uma maior valorização do bairro para as pessoas e para a cidade através de uma intervenção pensada e específica de um modelo pioneiro dos princípios do Movimento Moderno, contudo adaptado às necessidades actuais da sociedade.The purpose of this dissertation focused on a speech in Tarrafal District in the city of Guimarães, a project replicated with the principles of Alvalade district in Lisbon a requalification looking for a historical model to a large deterioration. At first it is fundamental to understand the social and economic state the country was after the Second world War, as well as the influence that the dictatorship had mentalities and architecture. Secondly the framework of the economic context of housing and its relationship with the needs of the time, never forgetting to characterize the underlying principles of these Economic Income Houses, describing the basis for clear model for understanding the principles replicated nationwide in different urban contexts. Finnaly a discussion will issue the Tarrafal Quarter and ace Guimarães city needs in order to further appreciation of the neighborhood to the people and the city through a thoughtful intervention and specific to a pioneering model of the Modern Movement principles, however adpated to the current needs of society

Natural Regeneration of Maritime Pine: A Review of the Influencing Factors and Proposals for Management

ReviewThe main objective of the present work was to review the current knowledge about the factors that influence the different phases of the natural regeneration of maritime pine (Pinus pinaster Aiton) and propose scientifically based management schedules. The review focused on the natural regeneration of maritime pine within its most representative areas (Portugal, Spain, and France). First, a brief characterisation of the main phases of the natural regeneration of maritime pine is described. Next, information on the factors affecting the natural regeneration of the species is provided, highlighting its positive and negative effects. Finally, management proposals are presented to promote the natural regeneration of maritime pine species. Numerous factors influencing the natural regeneration of maritime pine were identified. Fires and climatic factors can intervene in all three regeneration phases (seeding, germination, and seedling survival and development). The natural regeneration failure of maritime pine species can be aggravated in drier scenarios. Forest management plays an important role as it can promote the natural regeneration of the speciesinfo:eu-repo/semantics/publishedVersio

A crise financeira atual: origens, dinâmica, impactos e propostas de reforma do Sistema Financeiro Internacional

The outbreak of a financial crisis in scale may be linked to several factors, and it is certain that his understanding should be through analyzes that include the international financial system architecture. This study aims to understand the factors that led to the outbreak of the current financial crisis radiated in the United States and its subsequent course. Thus, we performed a study on the dynamics of the international financial system in recent decades, highlighting the role of financial institutions and agreements governing international finance, and geopolitical orientations of the dominant powers able to influence and shape the international financial system. To analyze the origins of the current financial crisis, we make use of theoretical perspectives of Keynesian and post-Keynesian, while critically present the theoretical perspectives of classical/neoclassical nature. Treat well to describe and analyze the origins and the course of the current financial crisis, emphasizing some of its impacts on national scales (especially the United States) and even regional (Europe and emerging countries) and to present some proposals to reform the international financial system, given the important that the issue has gained in recent years, especially in light of the drama of this crisis, which revealed both the weaknesses of the international financial system architecture as the need to promote changes to the solution of this crisis and prevent future crises.A eclosão de uma crise financeira em escala pode estar ligada a diversos fatores, e é certo que o seu entendimento deve se dar através de análises que incluam a arquitetura do sistema financeiro internacional. O presente trabalho busca compreender os fatores que levaram à eclosão da atual crise financeira irradiada nos Estados Unidos e seu subsequente desenrolar. Para tanto, realizamos um estudo acerca da dinâmica do sistema financeiro internacional nas últimas décadas, destacando o papel das instituições e acordos financeiros que regulam as finanças internacionais, e as orientações geopolíticas das potências dominantes capazes de influir e moldar o sistema financeiro internacional. Para analisar as origens da crise financeira atual, valemo-nos das perspectivas teóricas de corte keynesiano e pós-keynesiano, ao passo que apresentamos criticamente as perspectivas teóricas de cunho clássico/neoclássico. Tratamos assim de descrever e analisar as origens e o desenrolar da atual crise financeira, sublinhando alguns de seus impactos em escalas nacionais (destaque para os Estados Unidos) e mesmo regionais (Europa e países emergentes), bem como apresentar algumas propostas de reforma do sistema financeiro internacional, visto a importância que o tema vem ganhando nos últimos anos, especialmente diante da dramaticidade dessa crise, que evidenciou tanto as fragilidades da arquitetura do sistema financeiro internacional como a necessidade de se promover alterações para a solução dessa crise e prevenir futuras crises

Impact of fire recurrence and induced water stress on seed germination and root mitotic cell cycle of Pinus pinaster aiton

Climate change will increase the frequency of drought, heat waves, and wildfires. We intended to analyse how fire recurrence and/or induced water stress can affect seed germination and root cell division in Pinus pinaster Aiton. Seeds from stands with no prior fire history and from post-fire regeneration (in areas burnt once, twice, and thrice) in northern Portugal were germinated in distilled water (control) and polyethylene glycol (PEG) to simulate water stress for four weeks, followed by a recovery period. Roots were analysed cytogenetically. The germination index of the Pinus pinaster seeds was not statistically influenced by the induction of osmotic stress, nor by the fire recurrence of the stands. The mean germination time (MGT) was 10–29 days and 1–36 days for the stress and recovery periods, respectively, and increased with PEG concentration. The 20% PEG treatment inhibited root growth after germination. The 10% PEG treatment induced a high frequency of cytogenetic anomalies, mostly in the sites which experienced fire exposure. While fire recurrence did not affect the germination rate, it seemed to reduce the water stress response, negatively impacting cell division and impair root growthinfo:eu-repo/semantics/publishedVersio

MARINE QUALITY ASSESSEMENT OF AMAZON MANGROVES USING BENTHIC AND DIVERSITY INDICES BASED ON POLYCHAETE FAUNA

The aim of this study was to evaluate the impact of environmental disturbances in two mangroves in the Gulf of Maranhão, Brazil, based on the composition of polychaete communities. We collected samples from two sites: Buenos Aires stream, which is located near the Port of Itaqui, and Quebra Pote. We collected samples from three different zones at each site to evaluate possible gradients of environmental disturbance. We used biotic indices (AMBI, M-AMBI, BENTIX) and diversity indices to assess the level of disturbance. We found 731 specimens of polychaetes belonging to 11 families. The highest polychaete abundance occurred when there was a period of lower salinity in March 2014. The species Paraonis sp. and Syllis sp. were the most abundant. Further analysis of these indices revealed there were likely different sources of environmental disturbance between the two study sites. We suggest that at the Buenos Aires stream, the pollution probably comes from the sea towards the continent, whereas at the Quebra Pote, pollution is likely to originate from the continent and flow into the sea. We strongly encourage that thorough monitoring of mangrove forests is imperative for the survival and health of benthic communities

Micromorphology of the upper anthecium in Mesosetum Steud. and related genera (Poaceae, Arthropogoninae) and its taxonomic applications

Mesosetum is a Neotropical genus with 25 species, and 21 of them occur in Brazil. Mesosetum forms a clade closely related with Keratochlaena rigidifolia and Tatianyx arnacites. The objective of this work was to establish the taxonomic value of the upper anthecium micromorphology for the group. A total of 96 specimens, representing all Mesosetum species (except M. wrightii), K. rigidifolia and T. arnacites were examined under a scanning electron microscope (SEM). PCA and UPGMA analysis were applied using the micromorphologicalcharacters. Fifithteen useful taxonomic characters were identified. We highlight the following characters to distinguish the Mesosetum species: the presence, type and distribution of papillae on the abaxial surface of the upper lemma; the presence of unicellular macrohairs and bicellular microhairs; presence or absence of silica cells and the structure of the germination lid. The present work shows that the micromorphological characters identified are important taxonomically at the specific level, allowing the species identification in many cases

SiCKO and the commodification of life

SiCKO is a Michael Moore’s documentary that criticizes the United States health system and shows how political bargaining and lobbying from health insurers and pharmaceutical companies created a system that treats health as a commodity, martyring lives to earns profits. The comparison with other countries that have adopted socialized medicine, highlights an alternative health care proposal, that understands it as a citizen’s right, jointly funded by society and guaranteed by effective public policies and practices

ABDOME AGUDO OBSTRUTIVO POR DIVERTÍCULO DE MECKEL EM ADULTO

The Meckel Diverticulum is the most common congenital anomaly found in the small intestine. The change is caused by incomplete obliteration of the omphalomesenteric duct. Diverticular disease is usually asymptomatic and the likelihood of manifesting symptoms, such as bowel obstruction, decreases with age. Although most remain silent, it is important to always consider Meckel's diverticulum as a differential diagnosis in all patients with acute abdomen to avoid morbidity and mortality associated with late complications. The following report is about a rare case of obstructive acute abdome in adult patients caused by the presence of a meckel diverticulo.O Divertículo de Meckel é a anomalia congênita mais encontrada no intestino delgado. A alteração é causada pela obliteração incompleta do ducto onfalomesentérico. Geralmente a doença diverticular é assintomática e a probabilidade de manifestar sintomas, como obstrução intestinal, diminui com a idade.  Embora à maioria permaneça em silêncio, é importante sempre considerar o divertículo de Meckel como um diagnóstico diferencial em todos os pacientes que apresentem abdome agudo para evitar morbidade e mortalidade associada a complicações tardias.   Palavras-chave: divertículo de Meckel; obstrução intestinal; abdome agudo obstrutivo.

Ni crisis ni panaceas: dinámicas y transformaciones de los sistemas partidarios en América Latina

A nivel global, tanto en la literatura especializada como en el debate público, la desafección ciudadana hacia la cosa pública, el debilitamiento de los partidos políticos y el aumento de la abstención contribuyeron a asentar la idea de una crisis de los sistemas de partidos y de la democracia. Diferentes indicadores darían cuenta de esta crisis: el desarraigo social de los partidos que consagró el modelo del partido cartel (Katz y Mair 1995); el declive de la militancia (Van Biezen, Mair y Poguntke 2012; Whiteley 2011); la erosión de las estructuras partidarias tradicionales capturadas por el lobby corporativo (Crouch 2004 [2014], 112) o la tecnocracia; la pérdida de capacidad de los líderes para construir partidos programáticos que expresaran identidades políticas duraderas (Cheresky 2006; Dalton 2004; Luna 2014b); o su incapacidad para responder con una mayor deliberación interna a los desafíos de la representación política (Accetti y Wolkenstein 2017).Fil: Alenda, Stéphanie.
