As crises agrícolas, o sistema de colonia vigente na ilha, o excesso demográfico, a Guerra Civil entre 1820-1834, e um recrutamento militar obrigatório sem precedentes, afectaram o quotidiano dos madeirenses. Também a indústria do vinho, âncora da economia de exportação vinícola insular, entrou em declínio na segunda metade do século XIX, originando graves crises de subsistência. Todo este panorama contribuiu para uma onda emigratória dos insulares Madeirenses. Na ilha da Madeira existia uma colónia de mercadores ingleses e a ínsula era um importante interposto comercial britânico, nas rotas atlânticas das embarcações para as Índias Ocidentais. Na sequência da crise de mão-de-obra nas Antilhas Britânicas, com as proprietários a procurarem colonos para substituírem os antigos escravos, emancipados em 1834, os madeirenses eram vistos como bons candidatos, descritos como excelentes trabalhadores e artífices competentes. Surgiu, desde cedo, um sistema de aliciamento dos ilhéus para as plantações inglesas do Caribe. Em 1834-35 ocorreram as primeiras levas para a Ilha de Trindade, viagens garantidas pelo armador João de Freitas Martins e financiadas pelos proprietários da possessão inglesa. Entre 1834-47 saiu o maior número de madeirenses para a Ilha de Trindade, em toda a centúria oitocentista. O Anglicanismo praticado pelos britânicos na Ilha da Madeira era tolerado, mas não ensinado aos insulares, visto que havia uma religião de Estado em Portugal, o Catolicismo Apostólico Romano. Com a chegada do escocês Robert Kalley, em 1838, o pregador desencadeará um trabalho de propagação do protestantismo na Madeira e criará um número crescente de seguidores na ilha. Em 1846, criticado e acusado pelas autoridades civis e eclesiásticas, repudiado pela comunidade anglicana britânica, e perseguido pela população, sairá clandestinamente da Madeira. Muitos outros insulares também sairão da ilha, desembarcando a maior parte em Trindade, que estando próxima da costa da Venezuela, se tornará ilha de passagem para o vasto continente americano. Muitos ilhéus são os antepassados dos madeirenses presentes em Trindade, hoje elos de ligação com o passado, luso-descendentes activos da comunidade madeirense, a exemplo da Associação Portuguesa Primeiro de Dezembro, na história de Trindade e Tobago.

Os povoadores da Ilha da Madeira trouxeram muitas tradições e costumes oriundos das terras que provinham. Passaram esses hábitos para a nova terra e adequaram-se ao meio insular. O processo de ajustamento a esse meio incluiu adaptarem-se ao mesmo e atribuir localizações. Estudar a toponímia, ciência que estuda os nomes dos lugares, implica abordar as múltiplas componentes científicas que a ela estão interligadas e contextualiza-las no passado e no presente. Na Ilha da Madeira são poucas as publicações sobre a toponímia em comparação a Portugal Continental. Apesar do número pequeno, existem outros materiais de estudo como os primeiros testemunhos da povoação, justificações de atribuições entre outros documentos até mais antigos ao aparecimento desta ciência. Apresenta-se nesta investigação o resultado de uma pesquisa de vários tipos de materiais “texto” como: documentos específicos de várias entidades que têm o seu espólio no Arquivo Regional da Madeira (ARM), livros publicados, artigos, almanaques, roteiros e publicações periódicas; E “não texto” como: Plantas cartográficas de vários séculos da cidade do Funchal, pinturas e fotografias. O fato da área escolhida para estudo ser a Freguesia da Sé permitiu um estudo In loco e registo atual em fotografias dos locais públicos existentes e possíveis comparações aos registos anteriores. Agrupadas as características da zona estudada a nível social e urbanístico, justificam a evolução dos topónimos que tiveram as suas grandes alterações desde o final do século XIX até meados do século XX. A nível social os testemunhos estrangeiros traçam o panorama público e intercultural da Freguesia da Sé. A divisão dos topónimos por categorias, possibilitou várias conclusões sobre os assuntos da história madeirense como também a nível percentual, quais os grupos mais dominantes nesta freguesia e o porquê. Por fim, este estudo é um contributo para a história da toponímia na Ilha da Madeira, contextualizada essencialmente em termos históricos, linguísticos, sociais e urbanos.

A matemÆtica discreta Ø um dos ramos mais antigos da matemÆtica. Nos tempos mais recentes sofreu grandes avanos em especial na teoria dos grafos, a qual tornou-se numa poderosa ferramenta de anÆlise para entender e dar soluªo a vÆrios tipos de problemas complexos. O objectivo deste trabalho Ø contribuir para a obtenªo de possveis relaıes entre assuntos que partida poderamos pensar que sªo dspares (quando na realidade nªo o sªo), como coloraªo, planaridade e a existŒncia de matching em grafos. Esta dissertaªo Ø um trabalho de natureza reexiva, sobre a teoria dos grafos onde a ideia principal passa por questionarmos e discutirmos alguns temas pertinentes, deniıes e teoremas relacionando sempre com a planaridade dos grafos. DesenvolveremosumraciocnioecriaremosargumentosquefundamentemaexistŒncia de uma relaªo entre este tema e a coloraªo de grafos e a existŒncia de matching em grafos, utilizando exemplos e estabelecendo relaıes de causa e consequŒncia, deduzindo assim as respetivas conclusıes. Por vezes, os grafos nªo planares podem conter um aspeto visual um pouco complexo, devido aos vÆrios cruzamentos entre as suas arestas, originando assim um certo desencorajamento em utilizÆ-los como ferramenta para a soluªo de vÆrios problemas, quer sejam bÆsicos do quotidiano, ou mais complexos das mais vastas Æreas ligadas investigaªo. Um dos propsitos deste trabalho passa por desmisticar esta ideia e provar que existem muitas deniıes, propriedades, teoremas e algoritmos que podem ser aplicados em qualquer tipo de grafos, independentement da sua planaridade.

The Triennial Evaluation of Coordination for the Improvement of Higher Education Personnel (CAPES) is made according to several indicators, divided into several issues and items, and their weights. In these it is evident the importance of scientific periodicals. This study aims to evaluate the relative efficiency of post-graduate students in Business Administration, Accounting and tourism evaluated by CAPES in Brazil. The methodology used the data envelopment analysis - DEA (Data Envelopment Analysis). The data were obtained from the site and organized by the CAPES Qualis score. The analysis was performed by the DEA variable returns to scale, product-oriented (BCC-O), with data from the three-year periods 2004-2006 and 2007-2009. Among the main results are the average increase significantly the relative efficiency of the programs in the period 2007-2009 compared to 2004-2006 period, the highest average efficiency of programs linked to public institutions in relation to private, doctoral programs with the present average efficiency sharply higher than those only with masters, and senior programs in general were more efficient. There is also moderate and significant correlation between the efficiency scores and concepts CAPES. The Malmquist index analysis showed that more than 85% of programs had increased productivity. It is noteworthy that the main effect that influences the increase of the Malmquist index is the displacement of the border (Frontier-shift)

The south region of the Rio Grande do Norte has been historically recognized as a place of old indian villages. Inhabitants of the edges of the Catu River, border between the cities of Canguaretama and Goianinha, the Eleotérios in the threshold of 21st century had passed to be seen and self recognized as "remaining indians" of the RN. Their ethnic mobilizations, when becoming public had placed to the intellectual and political fields an old question to be reflected on: the asseverations concerning the "indian disappearing" in the State. This item brings with it other implications. Accessed by a para-oficial indigenism, the Eleotérios had started to establish political relations with the Potiguara indians of the Baía da Traição/PB and the Indian Movement, feeling stimulated to produce and to reproduce forms of social differentiation. In this context, this research is worried about elucidating the process of construction of the ethnicity among the Eleotérios, percepted from the social relations and politics kept with the amplest society, into a particular historical situation involving sugar cane fields owners, proprietaries, militants, researchers, ambiental agencies. The effects of these political and social relations had been extended, making Eleotérios appear to the society as susceptible social actors to the specific policies for the aboriginal populations

The coco de zambê is a dance of which origin is credited to old slaves who inhabited the coastalregion of Rio Grande do Norte. The zambê appears intensely in the narratives related to the past and present of Sibaúma, a quilombola community located in the southern coast of the state. It is conceived as a sign of ethnicity linked to a local black ancestry. The group is known as "remnant of Quilombo," and is demanding the process of territorial settlement, as guaranteed through the Brazilian federal constitution. The coco de zambê, presented as a kind of "certificate of ancestry to the group, besides, after a long period of abandonment, the dance is beeing "revitalized" and exploited by a part of the group alongside the demands for recognition. In this process there are several interlinked actors: NGOs, state agencies to promote the culture, representatives of public authorities and local leaders. Here, I'm interested in understanding how this process of revival occurs with the coco de zambê in Sibaúma: how a "brincadeira" (play) of the ancients comes to be a "cultural reference" and a means of political mobilization concerning their recognition

The towns presently named Pombal and Sousa, located in the hinterland of the State of Paraíba, Brazil, still keep vestiges of the colonization process they went through along the 18th and 19th centuries, when they both emerged as settlement nuclei in the extreme West of the then captaincy of Paraíba and attained the status of freguesia and vila in a later period. This research aims to comprehend the process of urban formation and development of the colonial urban nuclei of Pombal and Sousa as they became povoados (hamlets), freguesias (parishes) and vilas (small urban communities with a local government), according to territorial expansion policies implemented by the Portuguese government from 1697 to 1800. The choice of the two urban settlements for this survey lies in the fact that they were part of the great conquest and colonization program undertaken by the Portuguese Crown. Another aspect that was considered was the fact that those towns are the oldest urban nuclei of Paraíba s hinterland. They came into being as early as in the times of the colony, thus producing a favorable environment to the study of the changes that occurred in the captaincy s hinterland scenery resulting from the process of formation and development of the colonial urban space. Three fundamental categories of analysis were defined since they have a direct bearing upon the urban configuration of the two colonization nuclei: povoado, freguesia and vila. The three of them are related to civil and ecclesiastic jurisdictions. Field, documentation and bibliography surveys were undertaken in order to develop the study. They allowed for the finding of vestiges of the old, colonial urban structures and for the development of theoretical analysis based on present-day studies of issues relating to the colonial urban history. The study purposes were, therefore, to try to understand how the old urban nuclei of Pombal and Sousa fit in the territorial expansion policies undertaken by the Portuguese government; to relate the process of urban formation and development of such nuclei with the categories of analysis povoação-freguesia-vila by discussing the relations and influences they exert over one another and their territory, as well as to unveil, as much as possible, the configuration the urban spaces that were shaped along the 18th century

Considering that urban interventions, planned and executed recently at Natal, RN, should put Ribeira - one of the town centers - in the new limits of the expanded center of the city, this work examines the use of this new accessibility for the benefit of the development of an infrastructure to support a type of tourism currently seen as an alternative to diversification into areas dominated by entertainment tourism (the case of Natal). A local with city's traditional cultural facilities and holder of a set built that is a synthesis of the images of the neighborhood, it fears that this increase in the potential for movement and flows of use stimulate speculation and deployment of a bulk type of activity incompatible with the preservation the architectural heritage. Important economy for the city, tourism has been showing a factor propellant processing urban related changes in accessibility. It is argued that cultural tourism, often used in plans and projects of revitalization across the country, may be factor for sustainable development and conserve the assets, and contributes to the process of revitalization of the historic cultural center as Ribeira. Intended to illustrate the need to consider other information that might help in the revitalization of the neighborhood, this research presents the offer cultural tourism of Ribeira and identifies and maps certain physical attributes that, combined with functional attributes, can stimulate or inhibit the diversity and vitality in the region

This work analyzes the reutilization of real estate of patrimonial interest, come back toward habitation. One understands as real estate of patrimonial interest the old ones that present relevant architectural typologies that must be preserved; some buildings that represent characteristic architectural styles of a determined period; some valued real estates for the history of the city (historical, memory and image signification that has of certain places) and buildings with exceptional artistic elements. In short, real estate of patrimonial interest. The place or site to be studied will be the neighborhood of the Ribeira, because is an area that protects a bigger interest for the historic patrimony of the city. The habitation use was thought as a booster element of revitalization processes of degradable historic site, contributing to the preservation of artistic, architectural and historic patrimony, and thus to stimulate the accomplishment of the re-qualification of the neighborhood of the Ribeira. It is intended with the present study to examine alternatives to make possible habitation re (uses) in the historical quarter of the Ribeira in old constructions of patrimonial value

The oil production in mature areas can be improved by advanced recovery techniques. In special, steam injection reduces the viscosity of heavy oils, thus improving its flow to surrounding wells. On the other hand, the usually high temperatures and pressures involved in the process may lead to cement cracking, negatively affecting both the mechanical stability and zonal isolation provided by the cement sheath of the well. The addition of plastic materials to the cement is an alternative to prevent this scenario. Composite slurries consisting of Portland cement and a natural biopolymer were studied. Samples containing different contents of biopolymer dispersed in a Portland cement matrix were prepared and evaluated by mechanical and rheological tests in order to assess their behavior according to API (American Petroleum Institute) guidelines. FEM was also applied to map the stress distribution encountered by the cement at bottom bole. The slurries were prepared according to a factorial experiment plan by varying three parameters, i.e., cement age, contents of biopolymer and water-to-cement ratio. The results revealed that the addition of the biopolymer reduced the volume of free water and the setting time of the slurry. In addition, tensile strength, compressive strength and toughness improved by 30% comparing hardened composites to plain Portland slurries. FEM results suggested that the stresses developed at bottomhole may be 10 to 100 times higher than the strength of the cement as evaluated in the lab by unconfined mechanical testing. An alternative approach is proposed to adapt the testing methodology used to evaluate the mechanical behavior of oilwell cement slurries by simulating the confined conditions encountered at bottornhole

The coatings mortars are essential elements of building structures because they execute an important role in protecting walls and are particularly exposed to aggressive action responsible for its degradation over time. The importance of wall coverings has been the subject of discussion and analysis in the conservation and rehabilitation of old buildings. Are sometimes removed and replaced with inappropriate solutions of constructive point of view or architecture. The most commonly used coatings on walls of old buildings is based on traditional hydraulic lime mortars. The present study aims at the formulation of new lime- based mortars and aerial fine aggregate, in order to contribute to a better field of conservation and restoration mortar coating of old buildings. Residue was used for polishing porcelain as fine aggregate, replacing the aggregate (sand), in percentages 05-30% by mass. We conducted a thorough evaluation of the mortar properties in fresh and hardened state by comparing the performance of the same with a reference mortar. The residue used was characterized as the density, bulk density, and particle size laser, scanning electron microscopy, X-ray diffraction and X-ray fluorescence. Formulations were produced 7, 6 with residue and one commonly used formulation, which served as a reference. In the formulations of lime mortars air (hydrated lime powder CH-I) has been adopted a stroke volume (1:3) with constant binder, was varied and the water / binder and aggregate and waste. For evaluation of mortars fresh, proceeded to consistency analysis, specific gravity, water retention and air content embedded. In the hardened state assays were performed in specific gravity, water retention, modulus of elasticity, tensile strength in bending, compressive strength, water absorption by capillary action, adhesion, tensile strength, resistance to shrinkage and salts by of crystallization trials with resources chloride solution, nitrate and sulfate all sodium in prismatic at 90 days of age, in addition to the micro structural analysis of mortars. Based on the results we can see that the mortar formulated with 10% content of waste and the reference free retraction feature more stable closer to neutrality. The composition of 10% was obtained better performance against the action of the salt crystallization. The mortar with 15% residue obtained better density, lower air content embedded and high capacity for water retention developing good workability. The replacement of 20% of waste generates a satisfactory utilization of resistance to compression, flexion and traction grip the base. And, finally, it can be seen that the mortar with 10, 15 and 20% residual show, in principle, good suitability as coatings, thus enabling a final result consistent with durability, workability and aesthetics developing therefore a material with better performance to repair or replace existing mortars in old buildings

The use of gypsum, one of the oldest building materials for the construction industry in the country has been experiencing a significant and steady growth, due to its low cost and some of its properties that confer comparative advantage over other binder materials. Its use comprises various applications including the coating of walls and the production of internal seals and linings. Moreover, the fibers are being increasingly incorporated into arrays fragile in an attempt to improve the properties of the composite by reducing the number of cracks, the opening of the same and its propagation velocity. Other properties, depending on the function of the component material or construction, among these thermal and acoustic performances, are of great importance in the context of buildings and could be improved, that is, having better performance with this embodiment. Conduct a comparative study of physico-mechanical, thermal and acoustic composite gypsum incorporating dry coconut fiber, in the form of blanket, constituted the main objective of this work. Improving the thermal and acoustic performances of precast gypsum, used for lining and internal vertical fences of buildings, was the purpose of development of these composites. To evaluate the effect of fiber content on the properties of the composites were used to manufacture the composite layer with different thicknesses. The composites were fabricated in the form of plates with dimensions of 500x500x24mm. To facilitate the comparative study of the properties were also made with material gypsum boards only. We then determined the physico-mechanical, thermal and acoustical plaster and composites. The results indicated that the composites were significant gains in relation to thermal performance and also acoustic, in certain frequency range, increasing the thickness of the blanket. Concerning other physical-mechanical properties, the results showed that although the compressive strength was lower than for the composite did not occur after a fracture catastrophic failure. The same trend was observed with regard to resistance to bending, since the composites have not suffered sudden rupture and still continued after the load supporting point of maximum load

Os feijões estão entre os alimentos mais antigos, fazendo parte da alimentação diária da população brasileira. Objetivou-se com este trabalho determinar o período de convivência anterior à interferência das plantas daninhas (PAI) na cultura do feijoeiro em diferentes espaçamentos e densidades de plantas. Os tratamentos foram constituídos de períodos de convivência entre a cultura e as plantas daninhas, sendo zero a dez, zero a 20, zero a 30, zero a 40, zero a 50, zero a 60, zero a 70 e zero a 80 dias e mais uma testemunha sem convívio com as plantas daninhas. Além dos períodos de convivência, realizaram-se ainda estudos com espaçamentos entre linhas de 0,45 e 0,60 m e mais duas densidades de semeadura: dez e 15 plantas m-1. Adotou-se delineamento experimental de blocos casualizados, com quatro repetições. Quando o feijoeiro esteve presente com as plantas daninhas durante o ciclo, a produtividade dos grãos foi reduzida a 63, 50, 42 e 57% para os tratamentos com espaçamento de 0,45 m, densidades de semeadura de dez e 15 plantas m-1, espaçamento de 0,60 m e densidades de semeadura de dez e 15 plantas m-1, respectivamente. Os períodos anteriores à interferência (PAIs) da cultura foram de 23, 27, 13 e 19 dias após emergência, respectivamente.

The Passo da Pátria is one of the areas of housing in the city of Natal/RN, presents characteristics of insecurity on ways to live and access to goods and services. The project of urbanization called Integrated Project Passo da Pátria implemented since 2002 by the public power wants to change this picture. In Passo da Pátria system of classifications of space operated by the villagers signals to singularities that allows the identification of four pieces: Pedra do Rosário , Passo , Areado and Pantanal . The actions of the Project of Urbanization promote a new socio-space configuration. Our objective is to examine ways of appropriation of space in Passo da Pátria , built by the residents, which included their cultural practices giving symbolic meaning to the four pieces. The methodological procedures consisted of: literature review of the themes of the City, Urban, Segregation socio-space, Space, the Public Policies in urban area and texts on the Passo da Pátria ; desk research and interviews with old residents, recent residents, and these: men, women, young, and leaders of the Passo da Pátria . The evaluation of the data indicates that residents live positively the action of the public power as regards the expansion of urban infrastructure and services. At the same time, negative value of the shares removal of residents and idea of integration for the different pieces that form the Passo da Pátria , for them, these actions desconstroem times, experiences and narratives that are expressed in their relations with the space in which live
