Gerência de Memória

O material apresenta o gerenciamento de memória, realizado por meio do sistema operacional e manipulada por elementos específicos do hardware. Para que os processos sejam executados, é preciso que tanto seus códigos (suas sequências de instruções) quanto os dados que eles manipulam sejam carregados na memória principal. O gerenciamento do uso da memória tem grande influência sobre a quantidade de processos que podem ser executados ao mesmo tempo. As estratégias de gerência de memória realizadas por um Sistema Operacional estão relacionadas à decisões sobre como a memória será ocupada pelos processos, sobre o local onde cada processo deve ser carregado, por quanto tempo um processo deve permanecer carregado na memória, etc. Além desses aspectos, o material também destaca as principais estratégias de gerência de memória, os aspectos fundamentais sobre o funcionamento dos sistemas de memória; os mecanismos de gerenciamento de memória virtual, os sistemas monotarefa e monousuário, a relocação de endereços, o uso de registradores especiais no hardware, denominados registrador base e limite e a técnica de multiprogramação.

Lugares e pessoas do cinema na Madeira: apontamento para a história do cinema na Madeira de 1897 a 1930

O trabalho que se apresenta surge no âmbito do Mestrado em “Arte e Património, no Contemporâneo e Actual”. O assunto tratado é a história do cinema na Madeira, desde o seu aparecimento até ao final da década de vinte do século XX. A principal fonte usada foi a imprensa regional, uma vez que existem poucos estudos sobre o tema. Esta foi estudada entre Março de 1895 e Dezembro de 1930. Dada a extensão temporal estudada e alguns problemas técnicos (envio para microfilmagem, de algumas publicações, em Lisboa), a análise não foi tão exaustiva quanto o pretendido. Os jornais foram seleccionados de forma aleatória e de acordo com a sua disponibilidade no Arquivo Regional da Madeira. No primeiro capítulo faz-se um enquadramento histórico do assunto a estudar, onde se caracteriza a época e se analisa os primórdios do cinema de forma geral na Europa e em Portugal e, de modo mais específico, na Madeira. O segundo capítulo é relativo à exibição de filmes na Ilha, sendo esta análise efectuada para as décadas em estudo. O terceiro capítulo trata a produção cinematográfica na Madeira, onde são referidos os principais nomes de realizadores e/ou produtores locais e se apresenta uma listagem de filmes realizados e/ou produzidos por madeirenses ou filmados na Região.

Memória e promoção cultural madeirense na obra do Visconde do Porto da Cruz

A obra de Alfredo de Freitas Branco (Visconde do Porto da Cruz) cruza diferentes fases da sua vida, reflectindo, por isso, vários aspectos relacionados com as suas vivências. Sendo autor de uma vasta obra, fazem parte da sua bibliografia textos de diferentes temáticas e de estilos literários diversos, entre os quais, romances, novelas, contos, teatro, biografias, memórias, política, etnografia e estudos da natureza. Neste estudo, procuramos em linhas gerais, apresentar o seu percurso político e ideológico, no qual se inclui o Integralismo Lusitano, de modo a compreendermos o seu pensamento e compromisso com a sociedade do seu tempo. Fazemos uma breve abordagem à sua criação literária, marcada pela conjuntura histórica da época e destacamos a sua intensa actividade, como jornalista, fundador de revistas e de jornais, conferencista e membro de várias Associações culturais. Analisamos o seu percurso de vida, verificando que sempre se mostrou empenhado em dar a conhecer as suas raízes culturais e interessado em tudo o que representava o progresso do arquipélago, quer propondo ideias inovadoras, quer promovendo a Madeira, no território continental e no estrangeiro. O cerne deste trabalho foi investigar a sua obra, numa vertente cultural, observando o importante contributo no estudo, promoção e preservação da nossa memória cultural de madeirenses, através das recolhas que fez sobre múltiplos aspectos da cultura popular do meio insular, das diversas manifestações culturais do povo, nos seus usos e costumes, das danças, às músicas, ao traje, à alimentação, à medicina popular, às suas crenças e superstições. Observámos ainda os seus estudos do nosso património material, nos seus diversos monumentos; das artes visuais e da promoção dos artistas e intelectuais madeirenses que se evidenciaram na época. Este estudo propõe, também, algumas estratégias para dar a conhecer à comunidade uma parte da obra do Visconde do Porto da Cruz e despertar o interesse no estudo da mesma, a qual permanece ainda na penumbra.

Percursos de memória: uma análise de A costa dos murmúrios de Lídia Jorge e Terra sonâmbula de Mia Couto

O estudo comparatista incidirá nas representações da Guerra Colonial e Civil em Moçambique nas ficções A Costa dos Murmúrios (1988), de Lídia Jorge e Terra Sonâmbula (1992), de Mia Couto, explorando a noção de literatura de testemunho. A memória é o mecanismo de construção da identidade cindida e processo de crítica histórico-social e cultural, sublinhando os silenciados e os não-ditos da História Oficial. Em ambos os romances, analisaremos os choques de identidades culturais das principais personagens desde o período da colonização até à independência de Moçambique, insistindo nas personagens que assumem um papel de denúncia e de testemunha da História, construindo uma contra-leitura do História oficial. Refletiremos como as personagens centrais – Eva Lopo e Kindzu – denunciam o poder hegemónico ao ironizarem o papel dos anti-heróis. A narração de Eva Lopo e Kindzu reescreve as parábolas dos gafanhotos, o dilúvio, insistindo nos relatos do fim do mundo e nos testemunhos do inumano. Eva Lopo e Kindzu representam o regresso de Xerazade, dado que narram para criar consciência crítica e diferir a morte da memória numa perspetiva regeneradora da escrita.

Identidade, memória e narrativas na dança de São Gonçalo do povoado Mussuca (SE)

This study deals with the participation of the dance of São Gonçalo of the Mussuca town/SE, in the process of construction of the ethnic identity among this social group. The Mussuca is a grouping recognized as afro-descendents, linked with black enslaved people in the valley of the Cotinguiba region. The collective memory functions as a drive of this linking with the past and if it makes to elaborate narratives on this descent. The objective of this study was to investigate the ways the rite went through to constitute itself as an element of ethnic representation. Internal and external agents had been identified who had participated in different contexts. By means of an ethnographic work we ve reached some aspects of the local structure social which demonstrated the contradictions through the social relations of the group. This process of ethnic autorecognition presents the kinship and the space question as definers of the social arrangements which establish its ethnic boundaries

Os forrós da Serra da Gameleira (São Tomé/RN) : etnicidade, festa e sociabilidade

This work intends to describe and analyze the parties of forró that happen in Serra da Gameleira, in São Tomé/RN. Serra is a divided social space: groups of different ethnic origins live together in Gameleira de Baixo, Salgadinho (or Gameleira de Cima) and Chaves Belas. They are approximately two hundred families that live exclusively from agriculture. We try to understand how the parties inform about the social organization, the ethnic composition of the families that live there and the past of Serra, through the genealogy offorró players. In the discussion, we identify the festive places: in the total, we have Five houses of forró that function regularly one of them has been described. The private and public spaces inside them are intimate related, with no clear limits between the house of forró and the residence. Each house of forró has an owner, that regularly makes the parties, mobilizing a big part of the inhabitants, and provoking the straitening of the social relations. Observing the festive sociability between different social segments, the forró appears like na element that minimizes social conflicts, providing news ways of association and cooperation in the space of Serra da Gameleira. For the collection of facts, we used the ethnographic method, through the direct observation, interviewing and documentary research. The local history is recounted following the routes of oral memory and historical documents analysis. In the end of the analysis, we concluded that music and party are elements that aggregate the different groups that live in the location and determine forms of expression of what is seen as a traditional culture

De volta para os braços da rainha dos céus: migração, memória e festa em Caicó/RN

The present work has as an objective to seize up some particular meanings of the Feast of Sant Ana (The saint which represents the city of Caicó/RN), a central event of the calendar festive-religious of that city, looking for to perceive on how it combines with the symbolic poles sacred: profane through the social bonds that are present there performed and expressed through the social networking and of local belongings. Such bond ties reveal themselves through a very especial manner, through the migration of returning to the feast, when collectively are produced and updated knowledge and codes that reinforce the representation of the local belonging, nominated as being caicoense . We seek on perceiving how the many events of this feast (from a perspective of a religious order as well as laic) acting on a conclusive way to an identity of the re-meaning of that city, especially in its relation with the migrant natives: the sons and daughters that return to the arms of Sant Ana

Percepção ambiental do patrimônio cultural: estudo de caso na Cidade Alta e Ribeira em Natal-RN

Contemporary studies have shown that the evolution of the heritage concepts is accompanied by an affirmation of the importance of social participation in recognizing heritage values and in managing cultural assets. We used the Brazilian context to emphasize the challenges for democratizing this process. This problematic is discussed based on the cases of Cidade Altaand Ribeira, neighborhoods that date from the formation of Natal-RNand have cultural assets recognized by levels of government. The study builds elements to answer the research question: what meanings and representations does the culturalheritage in the case study have for its users? The research method analyzes the representations and the meanings of the neighborhoods, firstly is based on historiographical studies, memories records of the city and on the process of heritage management. Secondly, it isbased on the field research, it is structured in environmental perception studies (areas of Environmental Psychology, Architecture and Urbanism) and has been applied with users with different bonds with the studied environment (residents, workers and visitors). The data were obtained with the multi-method which included direct observation, questionnaire survey and mentalmaps (that replicate Kevin Lynch). The analysis of result verified the research hypothesis, emphasizing aspects of the relationship between users and cultural heritage relevant to strengthening collective memory, local identity, contributing to heritage management. Among the results, the socio-environmental image obtained which emphasized a "cultural axis" linkingboth studied neighborhoods and confirms the influences of elements rein the memories records of the city and in the area s management. Identified aspects to strengthen the relationship between the users and cultural assets, such as the presence of placeswith affective ties to certain groups, as well as the need to fight off negative images (of degradation and insecurity) associated to the site and also expand the participation of the population, including residents, in policies and cultural activities. After all, recognition of value and the involvement of societycultural assets have the potential of contribute to integrate city development with heritage conservation

Reutilização de imóveis de interesse patrimonial, voltados para a ahabitação: um estudo de caso na Ribeira-Natal/RN

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

Caldo do caldo: memória do espetáculo de dança paraibano caldo da cana

This research investigated the dance piece Caldo da Cana which premiered in João Pessoa-PB, in September 1984. It problematizes theoretical and practical way to make dance history, investigating this possibility through the dance itself. Arises from the fact that the dance has specific characteristics that can not be neglected by the historical account. In this sense, it was initiated by the raising of a theoretical framework that speaks to the indicated issues and unfolds through a field study, which included collecting testimonies from people who participated in the show, documentary research, gathering material traces and finally consists a practical part by transposing elaborated historical knowledge into the body through a creative process, resulting on this moment, in the construction of a duo dance

Perfil de memória e ativação de linfócitos T na leishmaniose visceral

Visceral leishmaniasis (VL) in Brazil is a disease caused by Leishmania infantum chagasi (L.i.chagasi). The clinical evolution post-infection depends on the vertebrate host immune response, which is genetically mediated. This study aimed to evaluate the immune response of individuals living in endemic area for VL in the state of the Rio Grande do Norte, considering individuals with VL under treatment (n = 9), recovered VL <1 year post treatment (n = 10), > 10 years posttreatment (n = 9), uninfected individuals living in endemic areas (n = 7), individuals that lost DTH response (n=6) and asymptomatic individuals for VL (n=9). Peripheral blood cells were evaluated in the presence and absence of soluble Leishmania antigens (SLA) and ex vivo, to determine activation, presence of regulatory cells and memory cells. The Leishmania parasitemia and anti-Leishmania antibodies were determined respectively by qPCR and ELISA. Cells from individuals with VL under treatment showed less cell activation after stimulation with SLA for the markers CD4/CD69, CD8/CD69 and CD8/CD25 compared with VL post treatment treatment (p <0.001). Apparently uninfected individuals have a higher cell activation than symptomatic VL (p <0.001), with the exception of CD8/CD25 marker (p = 0.6662). On the other hand, in the ex-vivo group, significant differences were observed for CD4/CD69, CD8/CD69 and CD8/CD25 between the 4 groups due to increased cell activation present in cells of individuals symptomatic LV (p <0.001). VL cells under treatment, ex vivo, have a lower percentage of memory cells (CD4/CD45RO and CD8/CD45RO) than individuals VL post-treatment or control group (p = <0.01). Likewise, individuals with symptomatic VL have fewer regulatory cells when stimulated by SLA [CD4/CD25 (p = 0.0022) and CD4/FOXP3 (p = 0.0016)] and in the ex-vivo group (p = 0.0017). Finally, DNA isolated from recovered VL contained Leishmania DNA, supporting the hypothesis of non-sterile clinical cure for Leishmania infection. Recovered VL, even 10 years after treatment have high levels of memory cells, which may be due to the presence of stimulation, either by reexposure to Leishmania or non-sterile cure

Visões da cidade : da cidade histórica aos bairros da Cidade Alta e Ribeira em Natal-RN

The present work is an initiative of undertaking a perspective that values the aspects of the city in its diversity. The one that t intends is to discuss the urbanity starting from the aspect of the image, of the history, and about main point, to value the point of the individual's view that lives the urban space in its more several configurations: the house, the street, the neighborhood, and the city in wider scale. The described historical research defines the city as space of the human accomplishments. When analyzing the moments of the most recent history of the urban life the modernity/post-modernity notions they are explored in the sense of illuminating the wealth, continuity and it breaks of patterns of behavior, and on the other hand, to describe a I overfly in the several times of the city. The prominences of aspects of the archaeology and of the descriptive resource they are related, for its time, the most punctual perspective of the practical research, the instance of the neighborhood, specifically High City and Riverside, configuring an immersion in the daily more punctual of the city, valuing forms of being, aiming the perspective of the personal computer as point-of-view. The images of the city assume the paper of representing the documental about the current features of the urbanity. It is without a doubt that at the present time the photographic image already possesses a paper of prominence it is as research instrument, be as main source for a work on files of photos. The photographic images in the present work possess a prominence place, focusing specific places of the city in the time. Finally, the individual's voice valued under the perspective on as the person's knowledge that inhabits and live the urbanity he/she understands the knowledge of the life in the city and, more than in any other place, a middle where the loss of action models is pointed very easily tends in view the dynamic movement of the practices and renewal of new indications; in the same space in that becomes urgent to build marks starting from which the individual can shimmer the future. And in that space the individual's voice is valued as rich source of information on living the scenery of conflicts of the present time

Memória e cultura: os Fulni-ô afirmando identidade étnica

Ce travail s agit du processus d´affirmation de l´identité Fulni-ô et de la mobilisation ethnique du groupe qui sont organisées et maintenues en bénéfice de leurs droits; ceux-ci consistent en la reconnaissance comme indiens devant la société et leurs droits sur le territoire. Le groupe est situé dans la municipalité d´Águas Belas, localisé entre l´ agreste et le sertão de l´état du Pernambuco. Ce sont, en moyenne, 3.676 indiens qui présentent comme signes d´identification ethnique: le Yathê, langue spécifique du groupe qui continue à être utilisée au quotidien; l´Ouricuri, terme qui désigne le rituel qui a lieu pendant le printemps et pendant des périodes spécifiques de l´année; le Toré, danse commune aux indiens du Nordeste. La mémoire et la matière culturelle sont les signes de mobilisation ethnique sélectionnés par les Fulni-ô pour favoriser l´affirmation de leur identité et la protection de leurs droits. Cet aspect sera traité tout au long de ce travail. La mobilisation ethnique est permanente, les Fulni-ô ne cessent d´utiliser des moyens qui peuvent les aider à vivifier leur identité et à protéger l´intégrité de leur territoire. Au travers de la mémoire ou grâce à l´utilisation de signes et de symboles ethniques (comme la langue, le rituel religieux et le Toré) ils consolident l´idée qu´ils sont indiens en même temps qu´ils établissent et défendent leurs frontières ethniques et physiques
