Avaliação geológica e geotécnica do maciço da Pedreira de S. Domingos n.º 2 (Armamar)

Neste trabalho, apresentam-se e discutem-se os resultados da aplicação da técnica de amostragem linear de descontinuidades em faces expostas do maciço rochoso da pedreira granítica de S. Domingos Nº 2 (Fontelo, Armamar; N de Portugal). É, igualmente, utilizada informação sobre a rede de fracturação regional, obtida através da análise morfoestrutural de mapas topográficos e mapas geológicos. São ainda referidos os métodos utilizados no tratamento dos dados de terreno com o objectivo de definir as famílias de descontinuidades e de caracterizar estatísticamente a sua atitude, espaçamento e extensão. Os resultados obtidos são comparados, à mega escala e macro-escala, no sentido de averiguar a presença de um padrão de fracturação com dimensão multiescala. Esta abordagem foi refinada através da aplicação de Sistemas de Informação Geográfica. A aplicação desta técnica para a caracterização da compartimentação do maciço poderá contribuir para aperfeiçoar a gestão sustentável do georrecurso da pedreira de S. Domingos Nº 2 (Fontelo). O controlo geomecânico do desmonte do maciço rochoso é salientado com o intuito de uma abordagem de geo-engenharia integrada dos maciços rochosos.

Aedes aegypti entomological indices in an endemic area for dengue in Sao Paulo State, Brazil

OBJECTIVE: To evaluate the most productive types of properties and containers for Aedes aegypti and the spatial distribution of entomological indices.METHODS: Between December 2006 and February 2007, the vector's immature forms were collected to obtain entomological indices in 9,875 properties in the Jaguare neighborhood of Sao Jose do Rio Preto, SP, Southeastern Brazil. In March and April 2007, a questionnaire about the conditions and characteristics of properties was administered. Logistic regression was used to identify variables associated with the presence of pupae at the properties. Indices calculated per block were combined with a geo-referenced map, and thematic maps of these indices were obtained using statistical interpolation.RESULTS: The properties inspected had the following Ae. aegypti indices: Breteau Index = 18.9, 3.7 larvae and 0.42 pupae per property, 5.2 containers harboring Ae. aegypti per hectare, 100.0 larvae and 11.6 pupae per hectare, and 1.3 larvae and 0.15 pupae per inhabitant. The presence of yards, gardens and animals was associated with the presence of pupae.CONCLUSIONS: Specific types of properties and containers that simultaneously had low frequencies among those positive for the vector and high participation in the productivity of larvae and pupae were not identified. The use of indices including larval and pupal counts does not provide further information beyond that obtained from the traditional Stegomyia indices in locations with characteristics similar to those of São José do Rio Preto. The indices calculated per area were found to be more accurate for the spatial assessment of infestation. The Ae. aegypti infestation levels exhibited extensive spatial variation, indicating that the assessment of infestation in micro areas is needed.

Data analytics in the cloud with flexible mapreduced workflows

Data analytic applications are characterized by large data sets that are subject to a series of processing phases. Some of these phases are executed sequentially but others can be executed concurrently or in parallel on clusters, grids or clouds. The MapReduce programming model has been applied to process large data sets in cluster and cloud environments. For developing an application using MapReduce there is a need to install/configure/access specific frameworks such as Apache Hadoop or Elastic MapReduce in Amazon Cloud. It would be desirable to provide more flexibility in adjusting such configurations according to the application characteristics. Furthermore the composition of the multiple phases of a data analytic application requires the specification of all the phases and their orchestration. The original MapReduce model and environment lacks flexible support for such configuration and composition. Recognizing that scientific workflows have been successfully applied to modeling complex applications, this paper describes our experiments on implementing MapReduce as subworkflows in the AWARD framework (Autonomic Workflow Activities Reconfigurable and Dynamic). A text mining data analytic application is modeled as a complex workflow with multiple phases, where individual workflow nodes support MapReduce computations. As in typical MapReduce environments, the end user only needs to define the application algorithms for input data processing and for the map and reduce functions. In the paper we present experimental results when using the AWARD framework to execute MapReduce workflows deployed over multiple Amazon EC2 (Elastic Compute Cloud) instances.

Cardiovascular profile after intravenous injection of Africanized bee venom in awake rats

The manifestations caused by Africanized bee stings depend on the sensitivity of the victim and the toxicity of the venom. Previous studies in our laboratory have demonstrated cardiac changes and acute tubular necrosis (ATN) in the kidney of rats inoculated with Africanized bee venom (ABV). The aim of the present study was to evaluate the changes in mean arterial pressure (MAP) and heart rate (HR) over a period of 24 h after intravenous injection of ABV in awake rats. A significant reduction in basal HR as well as in basal MAP occurred immediately after ABV injection in the experimental animals. HR was back to basal level 2 min after ABV injection and remained normal during the time course of the experiment, while MAP returned to basal level 10 min later and remained at this level for the next 5 h. However, MAP presented again a significant reduction by the 7th and 8th h and returned to the basal level by the 24th h. The fall in MAP may contribute to the pathogenesis of ATN observed. The fall in MAP probably is due to several factors, in addition to the cardiac changes already demonstrated, it is possible that the components of the venom themselves or even substances released in the organism play some role in vascular beds.

O acesso ao tratamento em saúde Mental na microregião de Itajubá/MG-Brasil

RESUMO: A integração da saúde mental à atenção básica é a recomendação feita para facilitar o acesso ao tratamento. A pesquisa teve por objetivo mapear e analisar os facilitadores e as barreiras ao acesso ao tratamento em saúde mental da Microrregião de Itajubá, estado de Minas Gerais, Brasil, composta por 15 municípios. A metodologia pautou-se na triangulação dos métodos, combinando a abordagem quantitativa e qualitativa de pesquisa. Para tal foi feito o mapeamento da capacidade instalada dos recursos existentes e identificação das principais lacunas com base nos parâmetros da saúde pública, a partir de roteiros de entrevistas e grupos focais com os principais atores sociais implicados. Constatou-se que o maior facilitador ao acesso ao tratamento tem sido a atuação das equipes de PSF (Programa Saúde da Família), que atuam diretamente nas comunidades. Outros facilitadores foram: a atuação dos CRAS (Centro de Referência de Assistência Social); a existência de um CAPS (Centro de Atenção Psicossocial), embora não credenciado ao SUS (Sistema Único de Saúde); Colegiados de Saúde Mental que promovem discussões, informação, educação, e pressionam os municípios para a implantação de serviços de saúde mental. A falta de “vontade política”, isto é, uma intervenção mais clara da gestão pública da saúde, com estabelecimento de prioridades para prover a ampliação do acesso, foi identificada como a maior barreira a ser enfrentada na microrregião, especialmente por falta de organização e planejamento das ações em saúde mental. Serviços que trabalham de forma isolada, sem a construção de uma rede; pouca participação política dos usuários dos serviços de saúde mental; e falta de recursos humanos, e profissionais pouco preparados para a função compõem as outras barreiras de acesso. Vê-se que diante dos facilitadores e barreiras expostos é preciso que os municípios realizem um levantamento sistemático, a fim de criar um plano de ação em saúde mental para compartilhar informações, recursos, serviços, disponibilidade, disposição e ações em rede.-------------- ABSTRACT: Integrating mental health care in primary-care services is recommended in order to improve access to treatment. Access to mental health treatment has been a worldwide debated theme. In Brazil, with the Psychiatric Reform, there has been a change of paradigm in the way of treating persons with mental disorders. Various health devices were created, building a net of treatment and care that replaces the asylum system and where human rights are respected and defended and the offered treatment is the closest possible to their social space. The research aims to map and analyse the barriers and the facilitators to mental health treatment in the micro-region of Itajubá, state of Minas Gerais/Brazil, made up of 15 counties. The methodology was based on the triangulation of methods, combining quantitative and qualitative research. For that, a mapping of the installed capacity of the existent resource was carried out; identification of the main voids based on the parameters of public health through scripts of interviews and focus groups with the social actors involved. It was found that the main facilitator to treatment has been the performance of PSF, who act directly in the communities. Other facilitators also stand out: the work of CRAS; the existence of CAPS, although not accredited to SUS; Mental Health Collegiate, promoting discussions, information, education, and forcing pressure on the counties for the implantation of mental health services. The lack of political will was identified as the major barrier to be faced in the micro-region, especially due to lack of organization and planning in the actions towards mental health. The services working isolatedly, without a communication net, and the lack of human resources as well as poorly prepared professional, are the main difficulties faced by access to mental health treatment. Becomes clear that the counties need to undertake a systematic survey towards creating a plan of action in mental health, in order to share information, resources, services, availability, disposition and networking.

Botnet cluster identification

Botnets are a group of computers infected with a specific sub-set of a malware family and controlled by one individual, called botmaster. This kind of networks are used not only, but also for virtual extorsion, spam campaigns and identity theft. They implement different types of evasion techniques that make it harder for one to group and detect botnet traffic. This thesis introduces one methodology, called CONDENSER, that outputs clusters through a self-organizing map and that identify domain names generated by an unknown pseudo-random seed that is known by the botnet herder(s). Aditionally DNS Crawler is proposed, this system saves historic DNS data for fast-flux and double fastflux detection, and is used to identify live C&Cs IPs used by real botnets. A program, called CHEWER, was developed to automate the calculation of the SVM parameters and features that better perform against the available domain names associated with DGAs. CONDENSER and DNS Crawler were developed with scalability in mind so the detection of fast-flux and double fast-flux networks become faster. We used a SVM for the DGA classififer, selecting a total of 11 attributes and achieving a Precision of 77,9% and a F-Measure of 83,2%. The feature selection method identified the 3 most significant attributes of the total set of attributes. For clustering, a Self-Organizing Map was used on a total of 81 attributes. The conclusions of this thesis were accepted in Botconf through a submited article. Botconf is known conferênce for research, mitigation and discovery of botnets tailled for the industry, where is presented current work and research. This conference is known for having security and anti-virus companies, law enforcement agencies and researchers.

Guarda prisional: força de segurança ou agente responsabilizador?

A permanently changing occidental society framework, simultaneously, to a world Globalization and a market liberalization, requires to know how important and which role the agents plays, in Estates representation, to guarantee their own intern security. Portugal is an example of that since has been integrated in European and world politics that allowed the borders opening, with all the negative consequences of that kind of measures. In way to struggle with those debilities emerge, in our Juridical Order, several security forces such as Prison Guards Corporation, whose contribute to intern security seems undefined and confuse, being urgent legislation in way to describe and clearly define their goals and functions. We begin with a brief history view to understand the evolution, focusing on the present moment, correlate several laws in way to clarify their juridical situation. Using a own critical sense, it draws attention to legislation lack problem in opposition to the conclusion that, Prison Guards Corporation is a security force with specialized expertise in matter and territory fields. Their activity occurs, generally, in penitentiaries where people see themselves without their freedom, legally determinated and confined to places as other individuals with deviant behaviors that deserve society refutation, establishing a separation period having rehabilitation as a goal – it is called general and special prevention. Penitentiaries specificities requires specially police force because penitentiaries are places where tensions are often, both between inmates and against employees, above all prison guards, the first to struggle inmates daily frustrations. In way that institutions achieve their purpose, it is necessary that citizens respect all the rules, although, to their efficacy is necessary to inflict punishment to those who did not respect the rules. Furthermore, it will be indispensable to act immediately in situations as impeding runaway helping, illegally standing in jail and to avoid violent acts against personal and patrimonial belongings. Juridical Order has a few security tools that are available to administration, in which is included coercive methods, that as damaging to citizens in whom they are use, are restricted, unavoidably, to inflexible control rules. Concluding, Prison Guards and Penitentiaries General Direction last goal is to give back recovered inmates to society, in a way to conduct their lives responsibly, without committing crimes.
