Caracterização e quantificação de resíduos de construção e demolição na Região Autónoma da Madeira

Esta dissertação foi desenvolvida tendo como objetivo principal quantificar e qualificar a produção dos Resíduos de Construção e Demolição (RCD) na Região Autónoma da Madeira (RAM). Estes resíduos são provenientes de atividades de construção civil, nomeadamente de obras de construção, reconstrução, ampliação, alteração, conservação e demolição e da derrocada de edificações. Os RCD devem ser, sempre que possível, reduzidos, reutilizados e/ou reciclados (3 R’s). Caso não seja exequível a aplicação direta em obra de um dos 3 R’s, estes deverão ser encaminhados para um operador de gestão licenciado com o intuito de os valorizar e/ou eliminar. Uma das opções mais usuais de eliminação de resíduos na RAM é a deposição legal em aterro. No entanto, ainda há resíduos que têm como destino a deposição não controlada, causando a degradação geral do ambiente da Região. Neste trabalho foram identificados os vários operadores de gestão de resíduos presentes na Região Autónoma da Madeira e quais os destinos finais de cada resíduo, classificado por código de acordo com a Lista Europeia de Resíduos (LER), segundo a Portaria n.º209/2004, de 3 de março. A informação da quantidade dos resíduos encaminhados para os operadores licenciados é transmitida, anualmente, à Direção Regional do Ordenamento do Território e Ambiente (DROTA), sendo possível determinar a tipologia e a quantidade de resíduos recebidos com respetivo destino final. Foi analisada bibliografia nacional e internacional sobre RCD com o objetivo de selecionar indicadores, em kg/m2 (quantidade de resíduos produzidos por área bruta de construção/demolição), mais ajustados às caraterísticas do edificado regional e respetivos processos construtivos. Da comparação entre os valores estimados de RCD produzidos com a quantidade de resíduos recebidos pelos operadores licenciados na RAM, foi possível estimar as quantidades recicladas e reutilizadas em obra e/ou depositadas ilegalmente. O resíduo estudado mais produzido foi o referente ao código LER 170107. Foi ainda, estimado um intervalo de produção total de RCD para a RAM, situado entre 93 e 507 kg/ano/habitante.

As quintas madeirenses como oferta turística diferenciada

Haver um investimento na preservação e restauro do património cultural na ilha da Madeira foi uma das principais questões levantadas durante a VI Conferência Anual da Ordem dos Economistas, realizada no dia 4 de Maio de 2012. Este restauro irá potenciar a valorização, utilização e rentabilização das quintas madeirenses, objecto de estudo desta dissertação, como património da Ilha da Madeira e como recurso sustentável turístico, económico e social da Região Autónoma da Madeira (RAM). Procura-se dar uma visão global da situação actual das quintas e propor perspectivas para a revitalização destes edifícios históricos com vista à sua valorização, através da sua utilização tanto pelo turismo da Madeira como pela população local. Esta proposta engloba a realização de circuitos turísticos de quintas madeirenses, assim como a reconstrução de algumas dessas quintas para o uso pela população local. Aqui será dado uma maior ênfase para a actual fase de intervenção contemplada no plano de estabilização financeira iniciado (2011-2014), bem como para a fase subsequente, circunstância em que será necessária a ajuda do sector privado para encontrar soluções economicamente sustentáveis que possam permitir estas propostas de valorização, rentabilização e auto-financiamento do património em questão. A dissertação está dividida em duas principais partes: na primeira é equacionado o estado da questão, faz-se uma inventariação e caracterização das quintas madeirenses, com os seus enormes espaços verdes e espaçosas casas, que tiveram um papel relevante no desenvolvimento no turismo, na sequência da procura de alojamentos, mas que hoje em dia estão condenadas ao abandono e degradação tanto do edifício como dos seus espaços circundantes; na segunda parte faz-se a análise e conclusão do potencial de valorização do recurso às quintas não só para o desenvolvimento de actividades para a população local como para o turismo da Ilha da Madeira, pondo em evidência a possibilidade de a actividade turística ser o alicerce máximo desse potencial.

Repercussões histopatológicas da colostomia no coto colônico distal desfuncionalizado: estudo experimental em ratos

O objetivo deste trabalho foi evidenciar as repercussões histopatológicas da colostomia no segmento desfuncionalizado e, dessa forma, criar um modelo experimental da colite de derivação fecal (CO). Foram utilizados 65 ratos, adultos, da raça Wistar, com peso variando de 220 a 300 g. Os animais foram divididos em 13 grupos, contendo cinco ratos. Do grupo 1 ao grupo 12, os animais foram submetidos a laparotomia mediana, sendo realizada uma colostomia terminal tipo boca única, e observados, por períodos variados de tempo, com o máximo de cem dias. Os animais, após serem mortos, foram necropsiados e retirado o segmento co1ônico desfuncionalizado para a avaliação histopatológica. Essa avaliação consistia de uma análise quantitativa, através da medida da espessura da mucosa colônica, e de uma análise qualitativa, mediante avaliação subjetiva: da presença de infiltrado inflamatório agudo ou crônico na lâmina própria; das alterações na arquitetura das criptas colônicas; da presença de hiperplasia folicular linfóide e de linfócitos na luz dos vasos da submucosa; e da presença de eosinófilos na luz intestinal. No grupo 12, após o 100° dia de pós-operatório (OPO), foi realizada a reconstrução do trânsito intestinal, e, após trinta dias, o cólon descendente foi retirado para a análise histopatológica. O método de Tukey e o teste "t" de Student foram utilizados como parte da análise dos resultados. Verificou-se uma redução estatisticamente significante da espessura da mucosa colônica a partir do 4000PO. Concluiu-se que a colostomia desfuncionalizante realizada em ratos reproduziu alterações histopatológicas compatíveis com a colite de derivação, e que estas mostraram-se reversíveis após a reconstrução do trânsito intestinal

Projeto em Áreas Consolidadas de Patrimônio Cultural: Propostas para a Construção de uma Metodologia de Ensino

Le thème du patrimoine culturel architectural et urbain continue d avoir une place importante dans le milieu technique et scientifique. Le concept s est élargi et aujourd hui comprend différentes procédures de projets d intervention. L importance accordée au thème amène à l inclusion de la matière de techniques rétrospectives et aux contenus qui en sont liés: conservation, restauration, restructuration et reconstruction d édifices et ensembles urbains, dans les parcours des cours d architecture et d urbanisme au Brésil établies par le Ministère de l Education Nationale (MEC) dans les années quatre-vingt-dix, postérieurement incorporés dans les directrices disciplinaires nationales. Nous partons des discussions théoriques et conceptuelles du Domaine du Patrimoine Culturel, ainsi que des principales théories pédagogiques d enseignements et d apprentissage articulées au projet. Dans ce contexte les objectifs principaux de cette thèse consistent à systématiser et à analyser les principales procédures méthodologiques contribuant pour la construction de méthodes d enseignement tournée vers des activités pratiques dans ce domaine. Pour cela, la recherche a été systématisée dans une approche à deux niveaux. En ce qui concerne le premier, basé sur des données secondaires, neuf cours d architecture et urbanisme ont étés identifiés entre institutions publiques d enseignement supérieur dont huit brésiliennes et une française, considérées représentatives en ce qui concerne les pratiques d enseignement de projet et de patrimoine culturel. Trente disciplines dédiées à la matière ont été également reconnues initialement, et postérieurement, cinq disciplines qui possèdent un emploi du temps dédié à la pratique de projet ont aussi été reconnues. Dans le deuxième cas, basée sur des données primaires, ont étés analysées les méthodologies et les stratégies d enseignement de projet basées sur les définitions des matières et des autres éléments des plans de travail avec des observations, des entrevues et des questionnaires en trois ateliers. Par rapport aux résultats nous avons constaté que toutes les écoles possèdent les contenus de la matière, mais peu d entre elles privilégient la relation du projet appliqué au patrimoine culturel. Nous avons constaté que les questions des projets dans ce contexte, même s elles sont considérées complexes, ont privilégié le listage et l analyse du site. L atelier qui intègre les fondements des théories de préservation, l histoire de l architecture et urbanisme et techniques anciennes et actuelles, est mis en valeur comme un modèle cohérent avec les propositions d intégration des connaissances théoriques et pratiques du projet appliqué à la discipline. Basé sur ces constatations il est possible de démontrer quatre étapes du projet appliqué au patrimoine culturel: 1ª) les fondements généraux qui concernent les bases théoriques sur la préservation, histoire et technique rétrospective, par exemple, l appropriation de lois et normes et la sensibilisation de l élève sur les questions de patrimoine culturel; 2ª) le contacte avec la réalité qui inclut l appropriation du problème à partir de ces acteurs, de ces échelles, de cette lecture de site et l analyse de l objet d étude; 3ª) le développement de la proposition qui inclut programmes (fonctions existantes et propositions), définitions du partit (types d intervention), conception (hypothèse et discussion) et définition de proposition; 4ª) la finalisation du projet qui consiste à développer la proposition avec sa représentation graphique et sa présentation finale. Nous concluons que le projet en Domaine du Patrimoine Culturel demande une attention spéciale et doit être présent dans les cursus considérant les principes généraux nécessaires à la formation de l élève. Le binôme projet / patrimoine signifie avoir dans le cursus universitaire les contenus et questions nécessaires les connaissances, les variables et possibilités existantes dans le projet appliqué au patrimoine culturel de façon à ce que ces connaissances soient incorporées dans l exercice de projet et n apparaissent pas comme un simple contenu théorique sans articulation avec la pratique. Naturellement ces conclusions n épuisent pas la réflexion sur la question. Nous espérons que les analyses faites contribuent à définir des méthodologies d enseignements capables d êtres vérifiées et testées dans la pratique en salle de cours, et puisse collaborer avec les nouvelles recherches surtout celles qui ont pour but des nouvelles théories pédagogiques d enseignement apprentissage du projet en Domaine du Patrimoine Culturel

Síntese e caracterização do poli(ácido láctico) para potencial uso em sistemas de liberação controlada de fármacos

With the advances in medicine, life expectancy of the world population has grown considerably in recent decades. Studies have been performed in order to maintain the quality of life through the development of new drugs and new surgical procedures. Biomaterials is an example of the researches to improve quality of life, and its use goes from the reconstruction of tissues and organs affected by diseases or other types of failure, to use in drug delivery system able to prolong the drug in the body and increase its bioavailability. Biopolymers are a class of biomaterials widely targeted by researchers since they have ideal properties for biomedical applications, such as high biocompatibility and biodegradability. Poly (lactic acid) (PLA) is a biopolymer used as a biomaterial and its monomer, lactic acid, is eliminated by the Krebs Cycle (citric acid cycle). It is possible to synthesize PLA through various synthesis routes, however, the direct polycondensation is cheaper due the use of few steps of polymerization. In this work we used experimental design (DOE) to produce PLAs with different molecular weight from the direct polycondensation of lactic acid, with characteristics suitable for use in drug delivery system (DDS). Through the experimental design it was noted that the time of esterification, in the direct polycondensation, is the most important stage to obtain a higher molecular weight. The Fourier Transform Infrared (FTIR) spectrograms obtained were equivalent to the PLAs available in the literature. Results of Differential Scanning Calorimetry (DSC) showed that all PLAs produced are semicrystalline with glass transition temperatures (Tgs) ranging between 36 - 48 °C, and melting temperatures (Tm) ranging from 117 to 130 °C. The PLAs molecular weight characterized from Size Exclusion Chromatography (SEC), varied from 1000 to 11,000 g/mol. PLAs obtained showed a fibrous morphology characterized by Scanning Electron Microscopy (SEM)

Remoção de ruídos sísmicos utilizando transformada de wavelet 1D e 2D com software em desenvolvimento

In the Hydrocarbon exploration activities, the great enigma is the location of the deposits. Great efforts are undertaken in an attempt to better identify them, locate them and at the same time, enhance cost-effectiveness relationship of extraction of oil. Seismic methods are the most widely used because they are indirect, i.e., probing the subsurface layers without invading them. Seismogram is the representation of the Earth s interior and its structures through a conveniently disposed arrangement of the data obtained by seismic reflection. A major problem in this representation is the intensity and variety of present noise in the seismogram, as the surface bearing noise that contaminates the relevant signals, and may mask the desired information, brought by waves scattered in deeper regions of the geological layers. It was developed a tool to suppress these noises based on wavelet transform 1D and 2D. The Java language program makes the separation of seismic images considering the directions (horizontal, vertical, mixed or local) and bands of wavelengths that form these images, using the Daubechies Wavelets, Auto-resolution and Tensor Product of wavelet bases. Besides, it was developed the option in a single image, using the tensor product of two-dimensional wavelets or one-wavelet tensor product by identities. In the latter case, we have the wavelet decomposition in a two dimensional signal in a single direction. This decomposition has allowed to lengthen a certain direction the two-dimensional Wavelets, correcting the effects of scales by applying Auto-resolutions. In other words, it has been improved the treatment of a seismic image using 1D wavelet and 2D wavelet at different stages of Auto-resolution. It was also implemented improvements in the display of images associated with breakdowns in each Auto-resolution, facilitating the choices of images with the signals of interest for image reconstruction without noise. The program was tested with real data and the results were good

Emprego dos ácidos graxos de cadeia curta na colite de derivação fecal : estudo em ratos Wistar

Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, after a colostomy. It is postulated that nutritional deficiency of the colonic epithelium by the absence of short-chain fatty acids (SCFA) is one of the factors responsible for the appearance of DC and that their employment could reverse the morphological changes of the mucosa. The treatment of choice for fecal diversion colitis (DC) is the reconstruction of the intestinal tract, although they suggested therapeutic options using enemas. This study evaluates the effect of SCFA in atrophy and inflammation in excluded colonic segments before and after the installation DC. Forty Wistar rats were divided into four groups (n = 10 for each group), submitted colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after postoperative day 40), for 07 days. Histological sections stained with HE were used for histological analysis of the thickness of the colonic mucosa excluded (t- Student p ≤0.05). Inflammatory reaction of the lamina propria and mucosa were measured with scores previously established (Mann Whitney p ≤ 0.05). There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 did not prevent the mucosal atrophy and significant increases in the numbers of lymphocytes (p=0.0006) and 50 eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

Imagens e contra-imagens do estado": considerações sobre a sociedade civil em Gramsci e Habermas

The theme of civil society has resonated significantly in the analysis of social science studies and has long been the center of public opinion, applied to a vast range of contexts, significances and political ideological connotations. Starting with such an unstable theoretical scenario, our research proposal scrutinized two civil society analysis traditions. Embodied by Antonio Gramsci and Jürgen Habermas, these politically conceptual differences are significantly divided into distinct interpretations of the relationship between the state and civil society. On one side, in Gramsci's work, we observe civil society as historically constituted through "molecular expansion of the state", organizing itself during its obligatory constitutive moment. On the other, Habermas shows us a civil society instituted from the structural differentiation process of society developed due to the contradiction existing between the different ways the state administration is organized, the economy and daily social interaction (in which it is found). As a consequence, civil society is no longer seen as a political arena and the hegemonic catalyst of the state, but as a social arrangement destined to increase the viability of the ethical and dialogical reconstruction of social life. It follows that the understanding of the distinctions between both models of civil society become crucial in the measure that they are divided in relation to the delineation of acting agents, fighting strategies, and to the objective of their actions.Despite the existence of analytical dissonance, we intend to outline the common points between both these civil society analysis traditions whose conflicting political action models lead us to a greater understanding of our contemporary political scene. This will be done starting with the systematization of both selected authors' principal categories, and through the introduction of the "contra-hegemonic public sphere" concept

O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

Democracia Possível: espaços institucionais, participação social e cultura política

The present study aims at making a theoretically reflection about the reconstruction process of democracy that can be observed in the country since the opening political process, which took place with the Geisel´s government in 1974, passing through the first civil president, in 1985, the Constitution process, in 1986, and finally the Constitution promulgation in 1988. It interests to this study analyses the premise that the 1988 Constitution inaugurates the moment in which democracy starts to be reconstructed in the country, and that this reconstruction is made in such a brand new way, once it included the possibility of participation of the civil society in the deliberation of the public politics, what became possible with the creation of new spaces of a gestion shared by the three executive powers: federal; states; municipalities, and with the civil society, in the councils created in those spheres. In this way, this work wishes to focus the opening process to the civil society participation, wich became possible with the creation of the city councils of public politics. It´s about investigating the form in wich the relations set up in these hibrid spaces could be considered democratic, inclusive and promoters of effective participation, checking up tendencies, giving emphasis to regularities and some specifities encountered in the forms of participation, which have been observed in those councils. In order to comprehend the democratic process in construction in the country, the analysis of the relations established by the civil society and the local executive power in the obligatory municipal councils is taken as object of study, passing by the tensions wich evolves institutions and political practices, permeated by the local political culture. It starts from a briefly review of works already made on the subject

Do olhar inquieto ao olhar comprometido: uma experiência de intervenção voltada para a atuação com alunos que apresentam paralisia cerebral

Compte tenu de l importance de la formation des enseignants pour répondre, de nos jours, aux besoins des élèves dont les caractéristiques marquantes sont la diversité et la différentiation, desquels nécessairement font partie , à un échelon croissant, des personnes atteintes d une déficience quelconque ; devant le constat que les actuelles politiques d éducation, en fonction de leurs limitations, peuvent être considérées comme un des principaux facteurs qui entravent la concrétisation d un vrai processus d inclusion de ces personnes ; compte tenu, encore, que le confront des situations éducatives concernant le processus d inclusion de ceux ayant des déficiences physiques, notamment lorsqu il s agit d élèves atteints de paralysie cérébrale, engendre chez les enseignants un état de troublante inquiétude du fait de ne se sentir convenablement préparés pour se confronter avec des situations pareilles, cette recherche, centrée sur cette problématique, a chosi comme objectif planifier, mettre en marche et analyser un programme d intervention pédagogique dans une école régulière de la ville de Natal/RN, auprès de quatre enseignants de l école fondamentale (7e Série) qui avaient reçu, dans leur classe, deux élèves atteints de paralysie cérébrale. S utilisant comme recours méthodologique de la recherche-action, le programme d intervention s est structuré autour de troix axes thématiques : l attitudinal, le pédagogique et le vécu en milieu scolaire, sous la forme de discussions théoriques et la mise en oeuvre de ces thématiques. Les données qui devraient être soumises à l analyse ont été collectées à partir des procédés d observation, d entretiens avant et après l intervention, du régistre de photos et d un questionnaire. Les interprétations faites, basées dans la comparaison du discours des sujets ont signalé que les enseignants ont progressé dans la maîtrise des savoirs scienfiques concernant la paralysie cérébrale et dans la connaissance des personnes atteintes par cette déficience. Par rapport aux valeurs et significations attribuées par les enseignants à ce programme d intervention à partir de leur choix des photos dans l ensemble du déroulement de ce processus formatif, elles s expriment par une prise de conscience très marquée, de la part des enseignants, par rapport :aux besoins éducatifs des élèves atteints de paralysie cérébrale ; à l importance et au vrai rôle que l école doit jouer face aux politiques d éducation inclusive ; aux difficultés vécues par ces personnes, qui réclament le plus profond respect de leurs ingularités ; la reconstruction d une nouvelle image concernant ces personnes ; la constatation qu il est possible aux enseignants d adapter et même de créer à l école des ressources et matériaux pédagogiques envisageant la qualité du processus d enseignement et apprentissage de l élève atteint de paralysie cérébrale ; finalement, la perception de l importance du travail en équipe, d un milieu scolaire accessible à ces personnes et de l appuis de la famille dans le contexte de l éducation inclusive. Les résultats obtenus, issus de ce programme d intervention, d après l évaluation finale des sujets, de part de témoigner de son efficacité, montrent que l intervention a été une excellente opportunité d habiliter ces enseignants et d améliorer le processus d enseignement à l école choisie comme le locus de cette recherche
