    The municipality of Monte Alegre, located in the Amazonian State of Para, Brazil, presents scattered areas with increased levels of natural radiation due to uranium rocks. The objectives of this dissertation were: to evaluate the mortality trend among Monte Alegre residents, and to compare it with that observed in neighbor municipalities (Alenquer and Prainha) without natural radiation sources; and to determine the impact of cancer distribution either in Monte Alegre or control counties population, taking into account their estimates of cancer incidence and mortality. The dissertation was organized in two papers. The first one aimed to evaluate the mortality trend for all causes of death, cancer, and unknown causes of death occurred between 1981-2005. Analyzed data was provided by the Brazilian National Mortality Information System (SIM), being the general population of the State of Para used as reference. In the second paper, cancer mortality risks at selected sites were ascertained using standardized mortality ratios (SMR) and mortality odds ratios (MOR). Additionally, cancer mortality risk ratios of Monte Alegre and control counties were obtained towards the ratio between SMRs of selected cancer sites in both areas. Three different sources of data were used to retrieve all cancer cases in the studied area, and therefore, to estimate cancer incidence in the studied populations: the diagnosed cancer cases at the regional reference centers for oncological care settled in Santarem, Belem and Manaus; the cancer-related hospitalization authorization records obtained at the Brazilian National Health System (SUS) registries; and primary data of cancer reported by local residents at a population-based health survey conducted by our research team in 2007-2008. A declining trend for all causes of death mortality in Monte Alegre general population, as well as for the unknown causes of death, was observed along the studied time series for both gender.

Analisaram-se: a produção média na fase adulta; a produção acumulada nas fases de crescimento e adulta; a massa média dos frutos e as características vegetativas de cada uma das variedades em estudo. O conjunto dos resultados indicou a Indiana Vermelha como a variedade mais produtiva entre as estudadas. Além desta, destacaram-se ainda, com altas produções, as seguintes: L2 P4 Vermelha, L4 P14 Branca, Monte Alto Vermelha, FAO 61, L7 P28 Vermelha e Torrão de Ouro, que não apresentaram diferenças significativas quando comparadas com a Indiana Vermelha. Com base nos valores das características vegetativas estudadas, concluiu-se que o maior desenvolvimento vegetativo não pode ser considerado como um parâmetro favorável às altas produções.The main objective of this study was to confirm the results already obtained, which determined high yields for twenty one guava varieties during the growing stage. These varieties were evaluated at the Experimental Station of Monte Alegre do Sul, Instituto Agronômico, State of São Paulo, Brazil. The following parameters were analysed: average yields in 1991-93 (adult plant stage; total production obtained in 1986-93 (growing and adult plant stages; the mean weight of the fruits and, vegetative characteristics of each variety. The `Indiana Vermelha', was the most productive variety. Other varieties, such as, L2 P4 Vermelha, L4 P14 Branca, Monte Alto Vermelha, FAO 61, L7 P28 Vermelha and Torrão de Ouro also presented high yields. No statistical differences were observed among them. According to the evaluation, the greatest vegetative growth cannot be considered as a suitable characteristic for high yields.

    Melo, Vicente de Paula

    1999-01-01

    The human being is constantly exposed to the natural radioactivity in the environment where he lives. This radioactivity comes mainly from materials present in the terrestrial crust that possess in their constitution chemical elements belonging to the radioactive families of uranium and thorium. The use of such materials for the construction of houses constitutes an important exposure form to the natural radiation, above all to the radioactive gas 222 Rn, that it is exhaled from them. The Brazilian soil is composed, among other, of minerals that contain appreciable concentrations of these elements. The inhabitants of Monte Alegre town in Para, located at 2 deg 00' 24,9 'S ; 54 deg 04 ' 13,5 W , used in the construction of their houses stones obtained from an area 20 km distant of Monte Alegre, denominated Ingles de Souza, located at 01 deg 56' 4 0,1 S; 54 deg 12 149,7 W, where a small residential village, denominated National Agricultural Colony of Para (CANP), is located. The objective of this work was to evaluate the indoor concentration of 222 Rn in the residences of Monte Alegre and CANP. Determinations of the 238 U and 226 Ra concentrations, measurements of the radon flux in samples of stones and soils of the two regions, as well as measurements to the gamma dose close of the soil and inside the residences, were also carried out. The average results of the radon concentration in the air of the investigated residences did not exceed the limits of 200 Bq. m 3 (action level) and 600 Bq. m 3 (intervention level) recommended by the International Commission on Radiological Protection (ICRP). The concentrations of natural radionuclides and the radon flux determined at the village showed values 17 times higher than those found at the urban area of Monte Alegre, while the average indoor gamma dose rate in the village residences was 0.86 mSv/a.

    Full Text Available The present study aimed to analyze the behavior of the Monte Alegre Formula (MAF and to quantify the heat focus detected by reference satellites, comparing them with the fires that occurred in Chapada dos Guimarães National Park from 2007 to 2015. Heat analysis was performed using images from AQUA, TERRA and NOAA satellites, whose daily data of detected foci were used to compose the time series over the years, allowing the analysis of trends in the numbers of foci for the park. The data were acquired in the platform of the National Institute of Space Research, in the historical data base of the National Institute of Meteorology and by to the manager of the park. In most years there was an overestimation of the number of heat sources in relation to the number of fire occurrences. The TERRA satellite presented values were closer to the number of fire records in the park. It was observed that 87.69% of the fires were validated in relation to MAF, where 60% belonged to very high hazard class and 27.69% were classified in the high hazard class, demonstrating the effectiveness of MAF in relation to records of fires occurring in the park.

    The municipality of Monte Alegre is a region that presents natural radiation high due to the presence of the radionuclide uranium ( 238 U) in its soil, which through its decay gives rise to element Rn, a gas. The radioactivity of the rocks has become a problem for the population of Monte Alegre, from the moment when the radioactive material began to be used in the construction of houses and paving of streets. Among all bio markers related to environmental exposures and its biological effects, the chromosomal aberrations are considered good bio markers as predictors of the risk of cancer. Studies suggest that the frequency of chromosomal aberrations may be related to the genetic instability individual and/or exposure to ionizing radiation. Our work aimed to evaluate the frequency of chromosomal aberrations in individuals in the region of high natural radioactivity in Monte Alegre-PA. As well as to correlate the cytogenetic analysis made in this study with the results of analysis of frequency of polymorphisms of genes of DNA repair carried out in another study that resulted in other dissertation. In accordance with the distribution of the data obtained in characterizing environmental radiological and in the calculation of dose, were chosen residents of homes with more and less exposure to radiation. The samples of peripheral blood of 85 individuals of the resident population of the region of Monte Alegre - PA were collected and examine provided two slides for individual was performed to verify the quality of the sample. Through this evaluation we decide that 33% of the material collected, or is, samples of 28 individuals were in suitable conditions for analysis of the frequency of chromosomal aberrations. After the collections lymphocytes present in the sample were cultivated in accordance with the methodology proposed for obtaining of cells in metaphase. were analyzed 6,177 metaphases of 28 individuals among which were found dicentric chromosomes 4 and 19 fragments

    Full Text Available Analisaram-se o desenvolvimento e a produtividade de progênies de cafeeiros de porte reduzido pertencentes aos cultivares san ramon, caturra e são bernardo, na região montanhosa de Monte Alegre do Sul. Tomou-se como padrão a progênie n.° 662 do cultivar burbom vermelho, de porte médio. Usou-se o delineamento em blocos ao acaso, parcelas subdivididas, com quatro e uma planta por cova em cada parcela a fim de avaliar a reação de 18 progênies nessas duas modalidades de plantio. De modo geral as progênies tiveram altura pouco maior quando plantadas a quadro mudas. Os dados de produção de café maduro no período de 15 anos indicaram que apenas algumas progênies não mostraram diferenças de produção quando plantadas a uma ou a quatro plantas por cova, enquanto outras revelaram diferenças significativas a favor do plantio a quatro mudas. Também mostraram que as progênies dos cultivares de porte pequeno produziram menos do que a de burbom vermelho 662. Os valores do coeficiente de correlação e o da interação entre a modalidade de plantio e produção das progênies indicaram que as melhores progênies plantadas a uma muda no geral também o são quando plantadas a quatro mudas por cova. Observou-se, ainda, que no plantio a quatro mudas as porcentagens de grãos chatos mostraram-se pouco menores e, as de grãos moca, pouco maiores, em relação ao plantio a uma única planta por cova.Progenies of the semi-dwarf cultivars San Ramon, Caturra and São Bernardo of Coffea arabica were analysed in relation to plant development, yield and seed characteristics in Monte Alegre do Sul, SP.

O objetivo da pesquisa foi desenvolver um instrumento gerencial para a avaliação do potencial de melhoria dos processos destas organizações. Para desenvolver o instrumento de diagnóstico foi considerada a realidade do setor de transporte por ônibus nesta capital e a base teórica referente aos sistemas de gestão baseados na melhoria dos processos, tais como os critérios de excelência do prêmio ANTP de Qualidade, os princípios da Mentalidade Enxuta e do Lean Management. A definição do valor a ser oferecido pelo serviço de transporte, com base na percepção dos usuários, é um ponto que aparece como de grande potencial de melhoria, bem como o equilíbrio entre demanda e capacidade instalada.This paper presents data and information collected in the second semester of 2004, in a multiple case study developed in three city public bus transportation companies, operating in Porto Alegre. The goal of the research was to develop an instrument for assessing the potential for streamlining processes in companies. To do so, it was considered the business scenario of companies and industry, and the theoretical framework presented in Lean Thinking, ean Management, Award Excellence Criteria of industry. Issues related to perceived value present the major gaps between the degree of importance and degree of application attributed by these companies. Secondary gaps refer to balancing service capacity and demand.

    This study aims to characterize the scolecodonts, trilobite pygidium fragments and fish remains of an outcropped region in the southern Amazonas Basin, comprising the uppermost section of the Monte Alegre Formation and the basal section of the Itaituba Formation. These, correspond to part of the marine portion of the Tapajós Group, related to an intracratonic carbonate platform. The Monte Alegre Formation includes a deposition of fluvial-deltaic and aeolian sandstones, siltstones and shales of interdunes and lakes, intercalated with transgressive carbonates of a shallow restrict nearshore marine environment. The Itaituba Formation comprises a thickest deposit of marine carbonates, representing the establishment of widespread marine conditions, and is the richest interval containing organisms of shallow marine environment in the Pennsylvanian of the Amazonas Basin. The associated fauna includes brachiopods, bivalves, gastropods, crinoids, echinoids, bryozoans, corals, foraminifers, sponges, ostracods, trilobites, scolecodonts, fish remains and conodonts, mainly in the packstones, and subordinately in the wackestones and mudstones. Conodonts Neognathodus atokaensis, Diplognathodus orphanus, Idiognathodus incurvus, and foraminifers Millerella extensa, Millerella pressa, Millerella marblensis, Eostaffella ampla, Eostaffella pinguis and Eostaffella advena characterizes a predominant Atokan age to the analyzed profile. The fossil association herein presented is taxonomically diversified and biologically interesting, comprising an important and well preserved, for the first time occurrence of two molds and two fragments of Proetida trilobites. Well preserved Eunicida and Phyllodocida scolecodonts and paleonisciform fish remains. These fossils help in the paleoenvironmental establishment of the studied interval in the Amazonas Basin and as a potential biostratigraphic and paleoecological tool to correlate regionally and globally the Pennsylvanian.

    The human exposure to ionizing radiation coming from natural sources is an inherent feature of human life on earth, for man and all living things have always been exposed to these sources. Ionizing radiation is a known genotoxic agent which can affect the genomic stability and genes related to DNA repair may play a role when they have committed certain polymorphism. This study aimed to analyze the frequency of polymorphisms (SNPs) in genes of DNA repair and cell cycle control: hOGG1 (Ser326Cys), XRCC3 (Thr241 Met) and p53 (Arg72Pro) in saliva samples from a population located Monte Alegre, state of Para were collected in August 2008 and 40 samples of men and 46 samples of women, adding a total of 86 samples. By RFLP was determined the frequency of homozygous genotypes and / or heterozygous for polymorphic genes. The I)OGG1 gene was 5% of the allele 326Cys, XRCC3 gene found about 21 % of the allele 241 Met and p53 gene showed 40.8% of the 72Pro allele. And the genotype frequencies of individuals for the three genes were 91.04%, 88.06% and 59.7% for homozygous wild genotype, 5.97%, 11.94% and 22.39% for heterozygote genotype and 2,99%, zero and 17:91% for homozygous polymorphic hOGG1 genes respectively, XRCC3, p53. These values are similar to those found in previous studies. The influence of these polymorphisms, which are involved in DNA repair and consequent genotoxicity induced by radiation depends on dose and exposure factors such as smoking, which is statistically a factor in public health surveillance in the region. This study gathered information and molecular epidemiology in Monte Alegre, that help to characterization of local population. (author)

    The human exposure to ionizing radiation coming from natural sources is an inherent feature of human life on Earth. Ionizing radiation is a known genotoxic agent, which can affect biological molecules, causing DNA damage and genomic instability. The cellular system of DNA repair plays an important role in maintaining genomic stability by repairing DNA damage caused by genotoxic agents. However, genes related to DNA repair may have their role committed when presenting a certain polymorphism. This study intended to analyze the frequency of single nucleotide polymorphisms (SNPs) in genes of DNA repair XRCC1 (Arg39-9Gln) and XPD (Lys751Gln) in a: population of the city of Monte Alegre, that resides in an area of high exposure to natural radioactivity. Samples of saliva were collected from individuals of the population of Monte Alegre, in which 40 samples were of male and 46 female. Through the use of RFLP (length polymorphism restriction fragment) the frequency of homozygous genotypes and / or heterozygous was determined for polymorphic genes. The XRCC1 gene had 65.4% of the presence of the allele 399Gln and XPD gene had 32.9% of the 751Gln allele. These values are similar to those found in previous studies for the XPD gene, whereas XRCC1 showed a frequency much higher than described in the literature. The. influence of these polymorphisms, which are involved in DNA repair and consequent genotoxicity induced by radiation depends on dose and exposure factors such as smoking, statistically a factor in public health surveillance in the region.

    Full Text Available A construção de reservatórios modifica a dinâmica natural de um rio interferindo no transporte de partículas sólidas, pois forma-se um meio artificial de retenção de sedimentos, provocando dentre outras consequências o assoreamento. A manutenção desses reservatórios para um uso mais eficaz e conservacionista é de fundamental importância. O presente trabalho buscou realizar um estudo no intuito de definir as potenciais áreas-fonte ao assoreamento do Lago da PCH Piedade, localizada no município de Monte Alegre de Minas – MG, por meio do mapeamento da suscetibilidade à erosão laminar e da densidade de drenagem. Assim, os dados de pedologia, declividade, uso e ocupação do solo e densidade de drenagem, foram levantados, analisados e sintetizados por meio de mapas. Os produtos cartográficos proporcionam um melhor entendimento das possíveis áreas produtoras de sedimentos que poderão gerar o assoreamento e desse modo fornecem subsídios para a prevenção e redução do carreamento de partículas para o lago. O mapeamento foi realizado em uma adaptação da proposta de Salomão (1994, in: GUERRA et al., 1999 para verificação da potencialidade à erosão laminar, e Guimarães (2008 que, além da erosão laminar faz análises morfométricas da área de estudo. Para elaboração dos mapas foi utilizado o software ArcGIS 9.2. O mapeamento apontou a existência de condições favoráveis ao controle do assoreamento em função dos aspectos naturais (como a baixa declividade na maior parte da área e a predominância de solos de erodibilidade moderada, porém quanto ao uso e ocupação do solo é necessária uma atenção mais efetiva, pois a maior parte da área de estudo é ocupada por pastagens e culturas.

O desejo e a realização de laqueadura tubária pós-parto constituem os eventos reprodutivos tomados como questões de análise. Os dados apresentados resultam de uma pesquisa desenvolvida em serviços de pré-natal nas cidades de São Paulo e Porto Alegre, que utilizou um desenho que combinou duas estratégias metodológicas: quantitativa, a partir de dados coletados em 427 prontuários clínicos, e qualitativa, por meio da observação etnográfica e realização de sessenta entrevistas em profundidade. A grande maioria de mulheres nas duas cidades manifestou o desejo de realizar a esterilização depois do parto. Entretanto, uma proporção muito maior de mulheres em São Paulo atingiu sua meta comparada a uma pequena proporção em Porto Alegre. A cultura médica local com relação à laqueadura, aliada à organização da prática de assistência ao pré-natal e parto, mostrou-se fator fundamental para compreender as diferenças encontrada nas duas cidades.This paper explores the factors associated with reproductive choices by HIV-positive pregnant women in two settings in Brazil, and particularly how health care providers and the local medical culture can affect these choices. Requesting and submitting to postpartum sterilization provide the focus of the analysis. The data come from a study conducted in prenatal care services in two cities, São Paulo and Porto Alegre. We employed two data collection strategies: collection of information from 427 patient records for HIV-positive women who had received prenatal care, and in-depth interviews with 60 women.

    One of the most relevant characteristics of the Pennsylvanian shallow-water carbonates of the Amazonas Basin is its diverse and well preserved invertebrate fossiliferous assemblages. In order to better understand the origin of these fossil concentrations, taphonomic data were obtained along well exposed areas of the uppermost part of the Monte Alegre Formation and basal part of the Itaituba Formation, which, based on conodonts, fusulinids and palynomorphs is of Atokan age. The taphonomic data focused on invertebrate organisms were supported by petrographic analysis. The understanding of the stacking pattern of the strata in the studied section allowed the identification of five type taphofacies, which contributed in the development of regional palaeoecological models, expressed as block-diagrams. These characterize the distribution of the environmental parameters, the composition of the faunal associations and the distribution and amplitude of the taphonomic processes that created the taphonomic signatures of the bioclastic elements throughout the supratidal to lower intertidal/deep subtidal depositional environments pertinent to the studied depositional environment. The regional palaeoecological models here presented are related to the particularities of the depositional environments of the studied rocks and are exclusive for the characterization of this intracratonic basin set influenced by high frequency climatic variations. Lithofacies, biofacies and taphofacies associations also reflect depositional conditions pertinent to the studied regional context, differing from the elements observed in modern intracratonic contexts analogous to the one studied, from different sedimentary basins around the world. Therefore, invertebrate taphonomy, supported by the analysis of sedimentary facies, fulfills the purposes recommended in this work, demonstrating its potential as a tool for palaeoecological analysis in the Pennsylvanian outcropping section in the southern

    Full Text Available RESUMOO presente artigo relata a elaboração de um modelo dinâmico de sistemas com o estudo de material reciclado proveniente de escombros para a fabricação de blocos de concreto do tipo não estruturais, utilizando para a modelagem das variáveis o programa computacional Stella. Essa modelagem permite que seja feita uma análise de cada variável do processo de produção, servindo como base para a definição das atividades críticas e as possibilidades de melhora e otimização do processo de produção, além de ser um critério de validação para uma adequada reutilização dos resíduos da construção, tendo em vista as legislações atuais e especificações técnicas e ambientais. Este estudo permitiu o desenvolvimento de um modelo conceitual de análise do processo de produção dos blocos através do comportamento que apresenta as variáveis que intervém no processo, demonstrando que a utilização de resíduos de construção e demolição neste estudo de caso é uma alternativa socioambiental com potencial econômico.

    Full Text Available O fenômeno paisagístico é um processo cultural que se estabelece a partir da interação entre sujeitos e espaço percebido. A paisagem é um fenômeno vivo, contínuo, que expressa diferentes tempos, materialidades e arranjos sociais. É a metonímia de um território. Tendo isso em vista, um grupo de pesquisa interdisciplinar buscou experimentar diferentes ferramentas teórico-metodológicas ao realizar o exercício de intervir em uma determinada paisagem urbana, e assim, estimular o debate sobre as controvérsias que lhe são inerentes. A problemática escolhida foi a proposta de cercamento do Parque da Redenção, oficialmente denominado Parque Farroupilha, discutida na Câmara de Vereadores de Porto Alegre (RS e na mídia local desde a década de 1990. Em uma área próxima ao lago Guaíba e ao Centro Histórico da cidade, os 40 hectares de área verde com diversos ambientes são um importante marco da paisagem de Porto Alegre. Caso fossem cercados, quais os aspectos da paisagem e outros que se agregam a ela que estariam sendo alterados? Como realizar uma intervenção para sensibilizar a população sobre as implicações do cercamento, ou não, do parque? Desde essas questões realizou-se o exercício, em 08 de novembro de 2014, cujos registros orientaram o debate e a produção deste texto e de um vídeo. Neste texto, procuramos inicialmente realizar um diagnóstico a paisagem estudada e a tensão evocada pela proposta de alterá-la mediante a instalação de uma cerca. A seguir relatamos uma intervenção realizada no local pelo grupo, como ferramenta metodológica para estimular diferentes reações e assim registrar as sensações e opiniões da população frente à alteração provocada naquela paisagem. Posteriormente, apresentamos reflexões sobre diferentes aspectos e implicações que o fechamento do parque poderá acarretar.

    Full Text Available The traditional management systems of landrace seeds have undergone transformations in the current Brazilian scenario of protection of varieties and organic certifications. In this context, the objective of this work is to discuss the vulnerability of these systems when facing the legal frameworks that legitimize and empower the formal seeds system and imposes requirements for the certification process of organic products, from the case study of Organismo Participativo de Avaliação da Conformidade Orgânica, linked to the Associação dos Produtores da Rede Agroecológica Metropolitana (OPAC-RAMA of Porto Alegre, Rio Grande do Sul. It is noticed that, despite the strong pressure from the legislation of varieties protection on the processes of autonomy of the farmers trying to keep them within a hegemonic system of conventional production, the current legislation of organics is encouraging the resumption of handling landrace seeds. Therefore, farmers' rights to their knowledge and management practices of their landrace seeds are resisting and seeking to become viable, strengthening the agro-ecological processes.

    Full Text Available Gender violence is any act or conduct based on gender which causes death, damage or suffering physical, sexual or psychological, both in the public and private sphere. Observing this definition, this article brings out violence against women occurred in Montes Claros/MG during the period from 1985 to 1993. During this period, the visibility of violence against women earns an enhancement, creation and inauguration of the Women’s Police Stations in various locations in Brazil. The methodology used is the discourse analysis and the sources are criminal proceedings and oral interviews. From the analysis of murder crime, we see how they are grounded in gender differences and still rooted in our society. / A violência de gênero consiste em qualquer ação ou conduta baseada no gênero que cause morte, dano ou sofrimento físico, sexual ou psicológico, tanto em âmbito público como privado. Partindo dessa definição, o presente artigo traz à tona a violência contra mulheres ocorrida em Montes Claros/MG no período compreendido entre 1985 a 1993. Neste período, a visibilidade à violência contra mulheres ganha um reforço: a criação e inauguração das Delegacias de Mulheres em várias localidades do Brasil. A metodologia utilizada foi a análise de discurso e as fontes foram os Processos-crime e Entrevistas Orais. A partir da análise de crimes de homicídio, observamos como os mesmos são alicerçados nas diferenças de gênero enraizadas e ainda presentes em nossa sociedade.

    Full Text Available Neste artigo, procurou-se verificar o que representam as cooperativas de trabalho no processo de reestruturação produtiva e flexibilização do trabalho na economia brasileira e, especificamente, na gaúcha. Desenvolveu-se uma pesquisa junto às cooperativas de Porto Alegre questionando-se quanto à flexibilização do trabalho, qualidade de vida e empregabilidade. Identificaram-se, por parte dos dirigentes a valorização dos ideais cooperativistas e a preocupação com a qualidade de vida dos cooperados. Essas cooperativas, no entanto, lutam com dificuldades, decorrentes da concorrência das cooperativas de "fachada", da legislação considerada restritiva e do fato de os contratantes de seus serviços buscarem o menor custo. Grande parte é constituída de trabalhadores com baixo nível de qualificação e que encontraram no trabalho cooperativo uma alternativa ao desemprego. Mesmo apontando as dificuldades deste tipo de organização consideram como uma solução à crise econômica e de se manterem no mercado de trabalho. Foram realizados posteriormente três estudos de caso de cooperativas de trabalho de Porto Alegre e comparados entre si. Como são cooperativas com diferentes níveis de qualificação de seus associados, as perspectivas e aspirações são bastante diferenciadas.

    Full Text Available Los efectos territoriales de los procesos de reestructuración capitalista no son exclusivos de las grandes áreas metropolitanas, se evidencian también en pequeños espacios urbanos. Es el caso de las localidades turísticas de la Costa Atlántica Bonaerense de Argentina, dónde la velocidad de los cambios y la aceleración de las transformaciones están conformando territorios inestables, es decir, escenarios geográficos en los que se perciben mutaciones continuas como producto de la implantación del modelo neoliberal y de las nuevas tendencias que asume el turismo en este contexto. El  objetivo consiste en analizar los procesos de transformación territorial y sus consecuencias en Monte Hermoso. Para ello se realizaron sucesivos trabajos de campo y se aplicaron técnicas de reconstrucción espacial por períodos para la elaboración de cartografía representativa de las transformaciones urbanas mencionadas. Los resultados de la investigación demuestran que los cambios favorecen a determinados sectores de la trama urbana, destinados al turismo neoexclusivo, generando una fragmentación del espacio en relación a las áreas que parecen no responder a las lógicas del capitalismo actual.

    Full Text Available The purpose of the present study was to estimate emissions of some pollutants (CO, NOX, HC, SOX, and PM in diesel fleet due to the addition of biodiesel in different blends, as well as to assess atmospheric pollutant concentrations in the metropolitan area of Porto Alegre (MAPA. The methodology was based on inventories from mobile sources based on US EPA's technical report. Regarding air quality the following parameters were determined: PM10, PM2.5, CO, NOX, O3, SO2, HC and PAHs. The results showed a decrease for emissions PM, CO, and HC, and a slight increase for NOX. The characterization of atmospheric pollutants in the metropolitan area of Porto Alegre showed that they are influenced by mobile sources, particularly diesel vehicles. The diagnosis of ratios analysis that was applied to facilitate the identification of sources of PAHs, indicated an influence of diesel oil.O objetivo do presente estudo foi estimar as emissões de alguns poluentes (CO, NOX, HC, SOX e MP na frota diesel devido à adição de biodiesel em diferentes misturas, bem como avaliar as concentrações de poluentes atmosféricos na região metropolitana de Porto Alegre (MAPA.

Em um projeto para atender às demandas represadas do nível primário ao secundário, denominado "Mutirão da Saúde", realizado em Porto Alegre, os médicos neurologistas do Hospital de Clínicas de Porto Alegre, após cada atendimento realizado, responderam a um instrumento para avaliar os encaminhamentos realizados pela rede de atenção primária à saúde (APS. A avaliação foi positiva, mostrando que os encaminhamentos foram realmente necessários em 85% dos casos; entretanto, foi parcialmente contraditória, tendo em vista que 41,7% dos encaminhamentos eram situações clínicas que deveriam ser manejadas no atendimento primário. A avaliação também revelou que 50% dos casos necessitavam de exames complementares. Devido a uma possível regionalização aleatória dos encaminhamentos, o resultado não nos possibilitou uma estimativa apropriada da prevalência por territórios das unidades de APS, informação esta importante para a organização do fluxo de encaminhamentos e planejamento dos recursos alocados pelos gestores, tanto locais quanto municipais.In the Unified Health System in Brazil (SUS, the levels of health care fall within the hierarchical model with the reference and counter-reference systems.

    Full Text Available As diferentes experiências participativas surgidas no Brasil na década de 1990 colaboraram para que o país tornasse-se, como diz Tatagiba, em "um celeiro de experiências inovadoras de gestão". Um dos destaques dentre as várias experiências de governança é o Orçamento Participativo (OP: programa que ao longo dos anos tem sido palco de intensos debates e estudos e colecionado admiradores e críticos. Entretanto, apesar de sua fama e dos diversos estudos, poucos buscaram avaliar o desempenho e a sensibilidade do programa ao governo eleito no município.

Ou seja, investigamos se a mudança de partido no controle da prefeitura, mantendo o OP em funcionamento, afetou, no entanto, seu desempenho. Nossa análise indica que o funcionamento do programa é bastante afetado pelo partido político que o implementa e que, portanto, o programa peca por baixa institucionalização, mesmo em seu caso de maior sucesso: o município de Porto Alegre.

    Full Text Available Este estudo, tem como o objetivo determinar a freqüência das hemoglobinopatias em neonatos, que realizaram a coleta para o Teste de Triagem Neonatal para Distúrbios Metabólicos no Hospital de Clínicas de Porto Alegre. O método utilizado para a determinação das variantes da hemoglobina, foi eletroforese por focalização isoelétrica em amostra de sangue total, coletadas em papel filtro por punção do calcanhar. Para confirmação diagnóstica dos casos alterados, foram realizadas eletroforeses das hemoglobinas em acetato de celulose com pH 8,6 e em citrato de ágar com pH 6,2, em amostra de sangue total dos neonatos e dos seus progenitores. Foram analisados, 1.615 indivíduos, e identificada a presença da hemoglobina S em 20 amostras e da hemoglobina C em seis amostras. Esses valores, correspondem a uma freqüência de 1,2% para o gene da anemia falciforme e 0,4% para o gene da doença de hemoglobina C, independente da raça ou ascendência. Esses dados, sugerem que a inclusão da triagem neonatal universal para hemoglobinopatias nos projetos já implementados para fenilcetonúria e hipotireoidismo congênito, apresenta vantagens e deve ser considerada pelos programas de saúde.

    The use of ionizing radiation in medicine allows great benefits. Nuclear Medicine uses ionizing radiation for medical diagnostic, such as: tumor, cancer, and dysfunctions location. However the use of ionizing radiation must be controlled in order to avoid likely biological effects in human beings. In order to extremely minimize that these effects appear, the Medical Physics Department of the Porto Alegre Clinical Hospital has implemented some procedures to assure that handling and use of radioactive material are in a safe way. This preoccupation is considered in all the places of nuclear medicine sector since the moment when the radioactive material is brought into including its manipulation and retirement, the exam process being accompanied.

Neste trabalho, é analisada a distribuição espacial de casos de mortalidade infantil, comparados a controles de nascidos vivos amostrados do Sistema de Informações sobre Nascidos Vivos da cidade de Porto Alegre, Rio Grande do Sul, Brasil. A modelagem adotada neste trabalho baseia-se em um processo pontual espacial, na qual se define uma medida de risco que varia continuamente sobre a região de estudo e estimada por meio de métodos de modelos aditivos generalizados. Essa abordagem possui a vantagem de permitir a incorporação, no modelo, de efeitos de determinantes individuais e ecológicos de risco sob forma simples e de fácil interpretação. Também permite a construção de contornos de tolerância que auxiliam na identificação de áreas de alto/baixo risco e de um teste global da hipótese nula de risco constante relativa à região. A aplicação do método aos dados de mortalidade infantil mostrou variação espacial no risco altamente significativa para mortalidade neonatal e não significativa para mortalidade pós-neonatal.Estimation and mapping of risk profiles are the main concerns of epidemiology. This paper analyzes spatial distribution of infant mortality cases as compared to live-born controls from Porto Alegre, Rio Grande do Sul. The modeling framework adopted in this research work is a spatial point process. Under this structure, a risk measure which continuously varies over the study region is defined and estimated using generalized additive model methods. This approach has the advantage of allowing for risk factors that are simple and easy to interpret. The procedure also allows the construction of tolerance contours which help identify areas of significantly high/low risk and an overall test for the null hypothesis of constant risk over the region. Application of this method to infant mortality data showed a highly significant spatial

    Full Text Available Introduction: Postmen are daily exposed to high levels of solar radiation, and lack of protection can result in many health damages. The present study aimed to identify cutaneous phototypes and evaluate the intake of oral photoprotectors by postmen. Methods: Cross-sectional study, carried out from August 2011 to December 2012 in the city of Porto Alegre, state of Rio Grande do Sul, Brazil. Socioeconomic and behavioral data regarding daily solar exposure were collected through a questionnaire. To evaluate the intake of beta-carotene, lycopene and omega-3, two 24-hour dietary recalls were applied. Cutaneous phototypes were assessed by Fitzpatrick’s classification.  Results: A total of 181 postmen were analyzed, whose mean age was 40.2±11.4 years old, and 140 (77.3% were male. The cutaneous phototypes II, III and IV were the most prevalent (n=138, totaling 76.3% of the sample. The median for the oral photoprotectors intake was 1.16 mg (0.46 – 2.29 of beta-carotene, 3.60 mg (1.01 – 6.31 of lycopene and 0.95 g (0.61 – 1.45 of n-3 fatty acids, all values significantly lower than the minimal doses to obtain photoprotective effect (p<0.001. The individuals in the group of phototypes V and VI showed lower adherence to the use of sunscreen and lower intake of beta-carotene, comparing to the other groups. Conclusions: The intake of oral photoprotectors is low in this population. Future studies may evaluate the real effect of oral photoprotectors, so that preventive measures using this approach can be included in photoprotection education actions for outdoor workers.

    Radiotherapy computational simulation procedures using Monte Carlo (MC) methods have shown to be increasingly important to the improvement of cancer fighting strategies. One of the biases in this practice is the discretization of the radioactive source in brachytherapy simulations, which often do not match with a real situation. This study had the aim to identify and to measure the influence of radioactive sources discretization in brachytherapy MC simulations when compared to those that do not present discretization, using prostate brachytherapy with Iodine-125 radionuclide as model. Simulations were carried out with 108 events with both types of sources to compare them using EGSnrc code associated to MASH phantom in orthostatic and supine positions with some anatomic adaptations. Significant alterations were found, especially regarding bladder, rectum and the prostate itself. It can be concluded that there is a need to discretized sources in brachytherapy simulations to ensure its representativeness. (author)

    Full Text Available Bayesian inference often requires integrating some function with respect to a posterior distribution. Monte Carlo methods are sampling algorithms that allow to compute these integrals numerically when they are not analytically tractable. We review here the basic principles and the most common Monte Carlo algorithms, among which rejection sampling, importance sampling and Monte Carlo Markov chain (MCMC methods. We give intuition on the theoretical justification of the algorithms as well as practical advice, trying to relate both. We discuss the application of Monte Carlo in experimental physics, and point to landmarks in the literature for the curious reader.

Designed by the engineer Afonso Hébert, head of the Department of Public Works in the State of Rio Grande do Sul/RS, the building was completed in 1922. In addition to functional elements, i.e., a large number of classrooms that would serve to increase the access of children to primary school, its monumental proportions incorporated a series of symbolic elements aligned with the ideals of the First Brazilian Republic (1889–1930. The documentary analysis was performed on the archives of the Directorship of Public Education and the Directorship of Public Works of Rio Grande do Sul, as well as various iconographic sources, capital improvement plans and periodicals of the time. The construction of the school inaugurated a new conception of the space and architecture of public elementary schools in the State, as the visible improvement and sanitation of the cities were considered of great importance in the period. The construction of school buildings was also one of the greatest advertising tools of the new Republican political regime.

Verificou-se que a prematuridade, em Porto Alegre, vem aumentando e, em 2008, foi de 9,9%. O risco de nascimento prematuro aumentou, em proporção inversa à do número de consultas de pré-natal (quanto menos consultas, maior o risco da prematuridade, e em mães com idade superior a 40 anos e naquelas submetidas ao parto cesáreo. Assim é possível indicar que o incentivo ao pré-natal e o desestímulo ao parto cesariano eletivo podem diminuir a prematuridade. Ainda é importante realizar mais pesquisas utilizando os bancos de dados disponíveis para indicar suas limitações e melhorar a qualidade dessas informações.

    Porto Alegre is the capital and largest city in the Brazilian state of Rio Grande do Sul in Southern Brazil with approximately 1.5 million inhabitants. The city lies on the eastern bank of the Guaiba Lake, formed by the convergence of five rivers and leading to the Lagoa dos Patos, a giant freshwater lagoon navigable by even the largest of ships. This river junction has become an important alluvial port as well as a chief industrial and commercial centre. However, this strategic location resulted in severe damage because of its exposure to flooding from the river system, affecting the city in the years 1873, 1928, 1936, 1941 and 1967. In order to reduce flood risk, a complex system of levees and pump stations was implemented during 1960s and 1970s. Since its construction, not a single large flood event occurred. However, in recent years, the levees in the downtown region of Porto Alegre were severally criticized by city planners and population. Several projects have been proposed to demolish the Mauá Wall due to the false perception of lack of flood risk. Similar opinions and reactions against flood infrastructure have been observed in other cities in Brazil, such as Itajaí and Blumenau, with disastrous consequences. This paper illustrates how the perception of flood risk in Porto Alegre has changed over recent years as a result of flood infrastructure, and how such changes in perceptions can influence water management decisions.

    The MORSE code is a large general-use multigroup Monte Carlo code system. Although no claims can be made regarding its superiority in either theoretical details or Monte Carlo techniques, MORSE has been, since its inception at ORNL in the late 1960s, the most widely used Monte Carlo radiation transport code. The principal reason for this popularity is that MORSE is relatively easy to use, independent of any installation or distribution center, and it can be easily customized to fit almost any specific need. Features of the MORSE code are described.

MÉTODOS: Estudo observacional e prospectivo. Os desfechos avaliados foram sobrevida em 30 dias e até a alta hospitalar, além de escore do Cerebral Performance Category (CPC I-II. RESULTADOS: De janeiro a outubro de 2008, foram atendidos 593 pacientes em PCR não traumática e foram realizadas 260 tentativas de ressuscitação cardiopulmonar (RCP. Houve sucesso inicial em 52 (20,0% casos, estando 16 pacientes vivos no 30º (6,0% dia, 10 tendo recebido alta hospitalar (3,9%, sendo que 6 (2,3% com escore CPC I-II. A PCR no domicílio associou-se inversamente com a sobrevida no 30º dia (p = 0,001 e na alta hospitalar (p = 0,02. Um ritmo inicial "chocável" (p = 0,008 associou-se à sobrevida aos 30 dias. O intervalo tempo-resposta e tempo colapso até início da RCP foram significativamente menores em sobreviventes aos 30 dias. Em análise multivariada, foram preditores independentes de mortalidade aos 30 dias um ritmo inicial chocável (razão de chance [RC] = 0,28 e intervalo de confiança [IC] de 95,0% = 0,10 - 0,81; p = 0,02 e PCR no domicílio (RC = 3,0 e IC 95,0% = 1,04 - 8,7; p = 0,04.

    Four typical Monte Carlo codes KENO-IV, MORSE, MCNP and VIM have been vectorized on VP-100 at Computing Center, JAERI. The problems in vector processing of Monte Carlo codes on vector processors have become clear through the work. As the result, it is recognized that these are difficulties to obtain good performance in vector processing of Monte Carlo codes. A Monte Carlo computing machine, which processes the Monte Carlo codes with high performances is being developed at our Computing Center since 1987. The concept of Monte Carlo computing machine and its performance have been investigated and estimated by using a software simulator. In this report the problems in vectorization of Monte Carlo codes, Monte Carlo pipelines proposed to mitigate these difficulties and the results of the performance estimation of the Monte Carlo computing machine by the simulator are described.

    Pityriasis versicolor is the most common of the diseases caused by Malassezia yeasts. The aim of this study is to determine the prevalence of pityriasis versicolor and its etiological aspects in the metropolitan area of Porto Alegre, Brazil. A retrospective cross-sectional study with data from patients of a reference hospital from 1996 to 2011 was performed. Collected data included: date, age, gender, ethnicity, anatomical region of lesion and the direct mycological examination results. Among the positive results in the direct mycological examination, 5.8% (2,239) were positive for pityriasis versicolor. The angular coefficient (B) was -0.3%/year, showing a decrease over the years. The disease was more prevalent in men (7.1% of men versus 5.1% of women that underwent the direct mycological examination); younger age (median 31 years old); "pardo" and black people (3.7% more than expected in the sample); trunk (73.44% of the affected anatomic sites). Lesions in rare sites (groin, genitals, legs, feet and hands) were also observed in this study. In conclusion, due to the decrease in the prevalence of pityriasis versicolor, long-term epidemiological studies in the metropolitan area of Porto Alegre, Brazil, are needed to continue the monitoring of this disease.

    The concept of Virtual Monte Carlo (VMC) has been developed by the ALICE Software Project to allow different Monte Carlo simulation programs to run without changing the user code, such as the geometry definition, the detector response simulation or input and output formats. Recently, the VMC classes have been integrated into the ROOT framework, and the other relevant packages have been separated from the AliRoot framework and can be used individually by any other HEP project. The general concept of the VMC and its set of base classes provided in ROOT will be presented. Existing implementations for Geant3, Geant4 and FLUKA and simple examples of usage will be described.

No transcurso dos grupos, os cuidadores ocuparam um espaço que chamamos metaforicamente de Oráculo de Delfos, lócus de acolhimento, escuta e de suporte. Escutar os diálogos travados entre equipe e cuidadores defrontou-nos com a contradição presente no discurso institucional que ao mesmo tempo que estimula o cuidado de si impõe normas, deveres e fazeres. O cuidado como direito de cidadania em contraposição ao cuidado como submissão e assujeitamento tensionou o grupo em vários momentos.

    Ancient Maya ports along the largely unstudied northeast coast of the Yucatan Peninsula once supported a network of trade routes linking people, goods, and ideas from across Mesoamerica. The Costa Escondida Project has focused on the interrelationships between the ancient Maya and their dynamic coastal environment along the shores of the Laguna Holbox. Central to our interdisciplinary efforts is a paleoenvironmental and paleoecological reconstruction of the key port of Vista Alegre - a low-lying island surrounded by a complex mosaic of costal ecosystems, sedimentological facies, and hydrological conditions. Geoarchaeological field methods, such as sediment coring, have made possible multiproxy analyses that enable us to better understand sea level fluctuations and the morphology of the shoreline and harboring locations over time, as well as changes in ecosystem biodiversity, which would have presented the maritime Maya with unique challenges and opportunities.

    The article analyzes conflicts and interests at one of Rio Grande de Sul's main centers for medical science, the Faculdade de Medicina de Porto Alegre. It explores the meaning and impact of the emergence of this specific, exclusive field of knowledge in a state where positivist principles of professional freedom were adopted by successive administrations during the early period of the Republic. Physicians there launched an entrenched war to uphold the principles of science over faith and politics, challenging the positivism of the party which held power in Rio Grande do Sul throughout the years. This perspective grew and developed in a climate of conflict and doubts among physicians, within a political context that differed from the rest of Brazil.

    The current paper sought to analyze the repercussions of Maria da Penha Law on addressing the issue of domestic violence against women in the city of Porto Alegre based on the view of professionals who constitute the care network for those women. Seven professionals, who work with the care for women who are victims of violence, were interviewed. Data suggests that the law has promoted changes in the field of violence prevention, assistance to women and punishment for the perpetrators, and it also increased the attention given to this phenomenon and enhanced female empowerment. It is concluded that the strengthening of the measures recommended by Maria da Penha Law still depends on investments in professional qualification, articulated actions between the places which provide assistance and the growing use of primary care services in order to improve the health of women and families exposed to violence.

The objective of this study was to characterize, classify and evaluate some issues about soil formation in Porto Alegre Botanical Garden, as well as relate their distribution on the landscape according to environmental characteristics. For the morphological description and collecting samples four profiles were selected (P1 to P4, located in the summit-shoulder transition, backslope, footslope and toeslope, respectively. Granulometric distribution of the P1 and P3 profiles indicated sharp textural gradient, with presence of textural and "plânico" B horizons, respectively, according to Brazilian System of Soil Classification. There is predominance of low values of pH, and low base saturation, with exception of P4, indicating probable deposition of solution material at this area. The Fed/Fes relationship was greater in the profile located in the summit-shoulder transition (P1, indicating higher weathering. The Feo/Fed relationship increased in P3 and P4 profiles, indicating greater participation of iron oxides of low crystallinity in reducing environment. The occurrence of some pedogenic processes may be inferred, like lessivage in P1 (Ultic Hapludalf, due to clay skins and higher values of fine clay:total clay relationship in subsurface; ferrolysis and gleization, by low pH value and high Feo/Fed relationship in E and EB horizons of P3 (Oxyaquic Hapludalf, being the last also present in P4 (Humaqueptic Endoaquent, indicating gleization occurrence.

Esa economía tuvo implicancias en su calidad de vida, debido a la carestía, especulación y pérdida progresiva del salario real. Asimismo, si bien desde la implementación del Estado Novo en 1937 el gobierno se proponía domesticar a los trabajadores, en 1942, con la intromisión del Brasil en la Segunda Guerra Mundial para lograr la intensificación de la producción, fue recortada la legislación que protegía a los trabajadores. Se pretende a partir del análisis de la escasez de alimentos y aumento del costo de vida, analizar cómo esto afectaba la vida de los trabajadores porto-alegrenses, y a su vez, cómo los trabajadores en 1945 inician un movimiento huelguista en el marco de la crisis del Estado Novo. From 1942 to 1945, the workers of Porto Alegre were immersed in what could be called a war economy. That economy had consequences in their quality of life, given the scarcity, speculation and progressive loss of the real wages. Also, despite the implementation of the Estado Novo in 1937, an attempt to placate the workers; in 1942, with the involvement of Brazil in the Second World War and with the purpose of intensifying production, the legislation that protected workers was whittled down.Considering the information about food shortages and the increase in the cost of living, the impact on the life of the Porto Alegre worker is analyzed, as well as, the manner in which in 1945, the workers started a strike movement in the context of the crisis of the Estado Novo.

    This introduction to Monte Carlo methods seeks to identify and study the unifying elements that underlie their effective application. Initial chapters provide a short treatment of the probability and statistics needed as background, enabling those without experience in Monte Carlo techniques to apply these ideas to their research.The book focuses on two basic themes: The first is the importance of random walks as they occur both in natural stochastic systems and in their relationship to integral and differential equations. The second theme is that of variance reduction in general and importance sampling in particular as a technique for efficient use of the methods. Random walks are introduced with an elementary example in which the modeling of radiation transport arises directly from a schematic probabilistic description of the interaction of radiation with matter. Building on this example, the relationship between random walks and integral equations is outlined

    Copyright © 2014, Association for the Advancement of Artificial Intelligence. In machine learning and statistics, probabilistic inference involving multimodal distributions is quite difficult. This is especially true in high dimensional problems, where most existing algorithms cannot easily move from one mode to another. To address this issue, we propose a novel Bayesian inference approach based on Markov Chain Monte Carlo. Our method can effectively sample from multimodal distributions, espe...

    The author discusses a recently developed algorithm for simulating statistical systems. The procedure interpolates between molecular dynamics methods and canonical Monte Carlo. The primary advantages are extremely fast simulations of discrete systems such as the Ising model and a relative insensitivity to random number quality. A variation of the algorithm gives rise to a deterministic dynamics for Ising spins. This model may be useful for high speed simulation of non-equilibrium phenomena

    A Monte Carlo algorithm to efficiently calculate static alpha eigenvalues, N = ne/sup ..cap alpha..t/, for supercritical systems has been developed and tested. A direct Monte Carlo approach to calculating a static alpha is to simply follow the buildup in time of neutrons in a supercritical system and evaluate the logarithmic derivative of the neutron population with respect to time. This procedure is expensive, and the solution is very noisy and almost useless for a system near critical. The modified approach is to convert the time-dependent problem to a static ..cap alpha../sup -/eigenvalue problem and regress ..cap alpha.. on solutions of a/sup -/ k/sup -/eigenvalue problem. In practice, this procedure is much more efficient than the direct calculation, and produces much more accurate results. Because the Monte Carlo codes are intrinsically three-dimensional and use elaborate continuous-energy cross sections, this technique is now used as a standard for evaluating other calculational techniques in odd geometries or with group cross sections.

    Full Text Available Resistance to several classes of antimicrobial agents is a remarkable characteristic of enterococcal strains increasingly reported worldwide. Information about strains isolated in the southern region of Brazil is still limited. In this study, a total of 455 consecutive enterococcal isolates recovered from patients living in Porto Alegre, Brazil, were identified at species level and evaluated for their antimicrobial susceptibilities by agar diffusion testing. The most frequent species was E. faecalis (92.8%, followed by E. faecium (2.9%, E. gallinarum (1.5%, E. avium (1.1%, E. hirae (0.7%, E. casseliflavus (0.4%, E. durans (0.4%, and E. raffinosus (0.2%. According to the results of disk tests 62.0% of the strains were resistant to tetracycline, 42.6% to erythromycin, 24.8% to chloramphenicol, 22.6% to ciprofloxacin, 22.0% to norfloxacin, 3.5% to ampicillin, 3.5% to nitrofurantoin. High level resistance to aminoglycosides was found in 37.8% of the isolates, with 23.5% being resistant to gentamicin, 14.3% to streptomycin, and 2.8% to both gentamicin and streptomycin. No vancomycin resistant or b-lactamase producing isolates were found. The results indicate that a significant percentage of isolates are resistant to different antimicrobials, pointing out the need for control strategies to avoid dissemination of resistant isolates and for continuous surveillance for the detection of emerging resistance traits.A resistência a várias classes de agentes antimicrobianos é uma característica marcante dos enterococos observada em diferentes regiões geográficas.

    Full Text Available Background: Studies on the use of psychoactive substances have been focused on identifying risk and protective factors related to this behavior based on the definition of the epidemiologic profile of such populations. The objective of the present study is to compare the profiles of samples of chemical dependent patients hospitalized at a Detoxification Unit (DU in Porto Alegre, state of Rio Grande do Sul, Brazil, in 2002 with the patients hospitalized in 2006. Method: This is a cross-sectional, descriptive and retrospective study. The research was carried out using medical records. We used a convenience sample divided into two groups: 1 all patients hospitalized at the DU from September to December 2006 (n=118; 2 all patients hospitalized at the same Unit from April to May 2002 (n=202. Results: There was a significant increase in the use of marijuana, inhaled cocaine and crack and a decrease in the use of solvents; there was no change concerning the use of alcohol and injected cocaine. It is important to mention the increase in the prevalence of crack users, which increased from 21.8% to 61.9%. There was a decrease of almost 30% in the number of alcoholics who did not use other psychoactive substances except for tobacco in the 2006 sample. Psychiatric comorbidities were quite prevalent, and we can highlight a significant increase in the number of patients with personality disorders. Conclusion: We conclude that the profile of chemical dependents hospitalized for detoxification is changing; therefore, it is important that new therapeutic strategies are planned in order to better assist this population.

    Prior work demonstrated the importance of nuclear scattering to fusion product energy deposition in hot plasmas. This suggests careful examination of nuclear physics details in burning plasma simulations. An existing Monte Carlo fast ion transport code is being expanded to be a test bed for this examination. An initial extension, the energy deposition of fast alpha particles in a hot deuterium plasma, is reported. The deposition times and deposition ranges are modified by allowing nuclear scattering. Up to 10% of the initial alpha particle energy is carried to greater ranges and times by the more mobile recoil deuterons. 4 refs., 5 figs., 2 tabs

    Full Text Available Citrus aurantium (bitter orange is characterized by the presence of p-synephrine, an amine structurally and pharmacologically related to ephedrine. Besides the same adverse effects as ephedrine, nowadays it is believed that altered levels of p-synephrine can be associated to the occurrence of migraine and cluster headaches. Leaves and fruits of this species are highly commercialized in form of teas and herbal preparations, but without taking into account the risks associated with its use. This work describes a survey of teas and herbal preparations containing C. aurantium, commercialized in Porto Alegre (RS/Brazil, in order to verify the presence of p-synephrine. Comparing with the mean amount available in the supermarkets, around 20% of the teas and 10% of the herbal preparations declared the presence of C. aurantium in their labels. In a sampling of 15 teas and 2 herbal preparations selected for the analysis, the presence of p-synephrine was characterized in all samples, with levels between 0.0040 to 0.2308%, leading to a caution that even being natural products, they are not free of adverse effects.Citrus aurantium (laranjeira-azeda é caracterizada pela presença de p-sinefrina, amina estrutural e farmacologicamente similar à efedrina. Além de poder causar efeitos adversos similares aos da efedrina, atualmente acredita-se que níveis endógenos alterados de p-sinefrina possam estar associados à causa da enxaqueca. Folhas e frutos desta espécie são largamente comercializados na forma de chá e em preparados de erva-mate, sem que sejam considerados os riscos associados ao seu uso. Neste sentido, este trabalho descreve uma pesquisa em chás e preparados de erva-mate comercializados em Porto Alegre, para verificar a presença de C. aurantium e p-sinefrina. Comparando com a quantidade média disponível nas prateleiras dos supermercados, cerca de 20% dos chás e 10% dos preparados de erva-mate declaravam nos rótulos conter C. aurantium. De

    Full Text Available The urban nucleus of the Porcelain Factory of Vista Alegre reveals a special interest in terms of the evolution of the traditional adobe construction in the town of Ílhavo, located in the district of Aveiro. Presenting a structured philosophy of intervention in the territory since its very beginning, it possesses a rich heritage in the field of construction and architecture. The measures planned and implemented in the second phase of Vista Alegre growth reporting its beginning to the ends of the 30's, and along the 40's, confirm it both in the rehabilitation, extension and new constructions in adobe masonry. Those measures were implemented during the structural changes of the Industrial Unit administration that only until this period belonged to the family of its founder. These changes creates one of the focus of innovation in the region, with new construction strategies and solutions in adobe buildings, which will prolonged the period of use of this construction system, noticeable in buildings dated of 1958 in the Vista Alegre and at least in 1970 in the town.

    The purpose of this study was to biomonitor metropolitan areas of Porto Alegre (Brazil) for PAHs associated with atmospheric particles and check their effects on the DNA of the land mollusk Helix aspersa. The sampling sites are located in an urban area with heavy traffic: (i) Canoas, (ii) Sapucaia do Sul, and (iii) FIERGS/Porto Alegre. The samples were collected during a continuous period of 24 hours during 15 days using Stacked Filter Units (SFU) on polycarbonate filters (two separated size fractions: PM{sub 10-2.5} and PM{sub <2.5}). The concentrations of 16 major PAHs were determined according to EPA. Comet assay on H. aspersa hemolymph cells was chosen for genotoxicity evaluation. This evaluation shows that, in general, the smaller PM-size fractions (PM{sub <2.5}) have the highest genotoxicity and contain higher concentrations of extractable organic matter. In addition, associations between chemical characteristics and PM carcinogenicity tend to be stronger for the smaller PM-size fractions. - DNA damage in H. aspersa exposed to atmospheric particulate in Metropolitan Area of Porto Alegre demonstrated association with PAHs in the fine filter (PM{sub <2.5}).

    Full Text Available ABSTRACTIn the Porto Alegre metropolitan region (PAMR there are a significant proportion of floodplain soils, mainly Planosols and Gleysols, in relation to upland soils. This study aimed to evaluate the morphological, chemical and physical characteristics, and to classify floodplain soils in the PAMR. Six soil profiles were evaluated under different sedimentary lithologies and drainage classes, and samples were collected for chemical and physical analyzes. Two orders of mineral soils (Planosols and Gleysols and one order of organic soil (Organosols were identified. The soils were moderately deep to deep and stratified. In mineral soils hue ranged between 7.5YR and 2.5Y, with the occurrence of Bg, Btg or Cg gley horizons, while in organic soil the colors were neutral. Sand and silt were the predominant particle sizes according to the origin sedimentary deposits. The organic carbon content was negatively related to soil density and positively related to soil specific surface area and with soil cation exchange capacity. Soil chemical characterization showed expressive variation in bases, aluminum and sodium saturation. Ki index and Fe(CBD/Fe(H2SO4 ratio indicated a low soil weathering degree. The different sedimentary lithologies and the soil hydromorphism degree were the main factors related to differences in morphological, physical and chemical characteristics of soils in the PAMR.

    Full Text Available This research project is based on the work of the External Causes Observer Group for Municipal Health Services under the Partenon and Lomba do Pinheiro District Administration in Porto Alegre, Brazil. It reflects on the actions and roles of Health Services in response to injuries due to External Causes, from the standpoint of strategies promoting health and quality of life. The high rate for these events prompted dissatisfaction among local healthcare parishioners, keenly aware that they constitute a serious Public Health problem. Coping strategies were initially intended to keep records of injuries due to external causes in this region, involving the entire team. Subsequently, the assistance rendered to victim of accidents and violence was examined. The findings of this group were presented at special events and community meetings, in addition to activities specifically addressing healthcare workers. Awareness-heightening and better qualifications are expected to underpin commitments to networking and the implementation of initiatives providing protection, particularly for more vulnerable segments.

    Full Text Available OBJECTIVE: To estimate the prevalence of lead poisoning in children and to identify associated factors, as well as possible local sources of contamination. METHODS: A cross-sectional prevalence study conducted in 2006 with a random sample of 97 children age zero to five years from a neighborhood in Porto Alegre, Southern Brazil. Blood lead levels were measured and a questionnaire administered to collect information on sociodemographics, recycling and dwelling. A preliminary environmental evaluation was carried out with direct analysis of soil and indirect analysis of air pollution with bioindicators to identify possible sources of contamination. To analyze lead concentrations from the different collection sites, for each type of material studied, ANOVA was performed with a Brown-Forsythe adjustment for heteroscedasticity and with Dunnett's T3 procedure for multiple comparisons of unequal variances. RESULTS: Blood lead levels > 10.0 µg/dL was found in 16.5% of children. Recycling of waste at home, low father's education level, and increased age of children were associated with increase blood lead levels. High lead levels were found in soil, and there was little indication of lead air pollution. CONCLUSIONS: A high prevalence of lead poisoning was identified, and the potential sources of contamination in this community appear related to waste recylcing activities. Studies should be conducted with other populations of Brazilian children and evaluate potential sources of local and general contamination, to accurately characterize this issue in Brazil.

    Femicide is the murder of women as the result of gender inequalities. It is the most extreme form of violence against women. The theoretical and methodological frame of reference used in this study was patriarchy theory and critical discourse analysis. We analyzed the discourses from 64 police inquiries categorized as femicides in Porto Alegre, Rio Grande do Sul State, Brazil, from 2006 to 2010. The victims were mostly poor young women living in outlying areas of the city with high rates of prostitution and women murdered by the drug traffic, deaths not routinely classified as femicides by the police. Many inquiries were shelved for purported lack of evidence, and many other cases were not even started. The discourse in the police reports often demeaned and blamed the victims, although some criticized the inequalities between men and women and identified the lethal effects of male chauvinism. Police inquiries are important sources for studying femicide in society, adding abundant information on the crimes' victims, perpetrators, and scenarios.

  7. Consumer behaviour towards organic food in porto alegre: an application of the theory of planned behaviour

    2013-03-01

    Full Text Available The aim of this study was to investigate consumers' decision-making process, attitudes and values towards organic food throughout the employment of the Theory of Planned Behaviour, adapting the methodology from a European project. 450 consumers were interviewed at supermarkets and farmers' markets in Porto Alegre, Brazil. Results indicate a high penetration level and very positive attitude towards organic products. Organics are believed to be healthier, tastier, more natural and environmental friendly, although being less attractive and more expensive than conventional food. Respondents from the farmers' market represent a specific segment whose values are more oriented toward society. The findings showed an alignment between positive attitude and consumption behaviour among the surveyed consumers. The study finally contributes to the stakeholders in general, since the knowledge of the attributes more valued by consumers can help retailers to play the role of coordinators of this supply chain, stimulating producers to adhere to organic certification, helping them to upgrade their production practices and improve their income. Consumers are also benefiting from this offer in the market.

    In the past two decades the members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. In the present study, we evaluated the antimicrobial resistance and genotypic characteristics of 203 Enterococcus spp. recovered from different clinical sources from two hospitals in Porto Alegre, Rio Grande do Sul, Brazil. The species were identified by conventional biochemical tests and by an automated system. The genetic diversity of E. faecalis presenting high-level aminoglycoside resistance (HLAR) was assessed by pulsed-field gel electrophoresis of chromosomal DNA after SmaI digestion. The E. faecalis was the most frequent specie (93.6%), followed by E. faecium (4.4%). The antimicrobial resistance profile was: 2.5% to ampicillin, 0.5% to vancomycin, 0.5% teicoplanin, 33% to chloramphenicol, 2% to nitrofurantoin, 66.1% to erythromycin, 66.5% to tetracycline, 24.6% to rifampicin, 30% to ciprofloxacin and 87.2% to quinupristin-dalfopristin. A total of 10.3% of the isolates proved to be HLAR to both gentamicin and streptomycin (HLR-ST/GE), with 23.6% resistant only to gentamicin (HLR-GE) and 37.4% only to streptomycin (HLR-ST). One predominant clonal group was found among E. faecalis HLR-GE/ST. The prevalence of resistance among beta-lactam antibiotics and glycopeptides was very low. However, in this study there was an increased number of HLR Enterococcus which may be spreading intra and inter-hospital. PMID:24031416

    Method of Monte Carlo integration is reviewed briefly and some of its applications in physics are explained. A numerical experiment on random generators used in the monte Carlo techniques is carried out to show the behavior of the randomness of various methods in generating them. To account for the weight function involved in the Monte Carlo, the metropolis method is used. From the results of the experiment, one can see that there is no regular patterns of the numbers generated, showing that the program generators are reasonably good, while the experimental results, shows a statistical distribution obeying statistical distribution law. Further some applications of the Monte Carlo methods in physics are given. The choice of physical problems are such that the models have available solutions either in exact or approximate values, in which comparisons can be mode, with the calculations using the Monte Carlo method. Comparison show that for the models to be considered, good agreement have been obtained

    PMC (Parallel Monte Carlo) is a system of generic interface routines that allows easy porting of Monte Carlo packages of large-scale physics simulation codes to Massively Parallel Processor (MPP) computers. By loading various versions of PMC, simulation code developers can configure their codes to run in several modes: serial, Monte Carlo runs on the same processor as the rest of the code; parallel, Monte Carlo runs in parallel across many processors of the MPP with the rest of the code running on other MPP processor(s); distributed, Monte Carlo runs in parallel across many processors of the MPP with the rest of the code running on a different machine. This multi-mode approach allows maintenance of a single simulation code source regardless of the target machine. PMC handles passing of messages between nodes on the MPP, passing of messages between a different machine and the MPP, distributing work between nodes, and providing independent, reproducible sequences of random numbers. Several production codes have been parallelized under the PMC system. Excellent parallel efficiency in both the distributed and parallel modes results if sufficient workload is available per processor. Experiences with a Monte Carlo photonics demonstration code and a Monte Carlo neutronics package are described

    Full Text Available Introdução: Em menos de 40 anos, o Brasil passou de um perfil de mortalidade típico de uma população jovem para um perfil caracterizado por enfermidades complexas e mais onerosas, próprias das faixas etárias mais avançadas. O controle dos sintomas de pacientes em cuidados paliativos pode melhorar a qualidade de vida desses indivíduos e até mesmo de suas famílias. A utilização de medicamentos adequados para a terapia desses pacientes é fundamental para o sucesso do tratamento, que nesse caso é o controle adequado dos sintomas. O objetivo principal do trabalho foi descrever o perfil de utilização de medicamentos em pacientes em cuidados paliativos internados no Hospital de Clínicas de Porto Alegre (HCPA. Métodos: O presente estudo descritivo, exploratório tem por objetivo determinar o perfil de uma amostra de 30 pacientes internados na unidade de cuidados paliativos do HCPA com enfoque na utilização de medicamentos e também nas características demográficas e clinicas e o desfecho clínico dos pacientes. Resultados: As prescrições levantadas totalizaram 76 medicamentos diferentes; dentre estes, os mais prescritos foram morfina, dipirona, lactulose, heparina, metoclopramida, paracetamol, cloreto de sódio, ondansetron, ipratróprio, dexametasona e omeprazol. Com a possibilidade de acúmulo de patologias crônicas, a polifarmácia é inevitável. A avaliação do uso dos fármacos torna-se de grande importância para que se garanta a segurança do paciente em cuidado paliativo e o uso racional de medicamentos. Conclusão: A construção metodológica deste estudo possibilitou descrever o perfil da população de interesse, além de gerar conhecimento sobre os medicamentos utilizados na unidade de cuidados paliativos e sobre variáveis demográficas e clínicas de pacientes internados nessa unidade.

Compilaram-se dados obtidos da literatura quanto à composição de espécies de aves em 14 áreas verdes. Realizou-se análise de similaridade (Jaccard com o propósito de comparar a composição de espécies entre distintas áreas verdes. Utilizou-se análise de regressão múltipla, aplicando-se o método stepwise, para testar se a riqueza de espécies de aves é influenciada pelas seguintes características das áreas verdes urbanas: dimensões, variedade de hábitats, área e distância do vizinho mais próximo. Compilou-se um total de 224 espécies de aves para as áreas verdes consultadas. A análise de Jaccard demonstrou que áreas de maiores dimensões apresentaram composição similar entre si e distinta de áreas de menores dimensões. O teste de regressão múltipla indicou que houve correlação positiva entre a riqueza de espécies e os fatores estudados, exceto pela distância entre as áreas. Concluiu-se que áreas verdes de maiores dimensões e com maior heterogeneidade de hábitats podem sustentar maior riqueza de espécies de aves em ambientes urbanizados. Entretanto, a importância de áreas pequenas não deve ser desprezada, especialmente nos casos em que se constituem nos últimos ou principais remanescentes de determinadas espécies.

    Monte Carlo methods form an experimental branch of mathematics that employs simulations driven by random number generators. These methods are often used when others fail, since they are much less sensitive to the "curse of dimensionality", which plagues deterministic methods in problems with a large number of variables. Monte Carlo methods are used in many fields: mathematics, statistics, physics, chemistry, finance, computer science, and biology, for instance. This book is an introduction to Monte Carlo methods for anyone who would like to use these methods to study various kinds of mathemati

    Full Text Available The mutagenic activity of airborne particulate matter collected from three different sites within the urban area of Porto Alegre, Brazil, was investigated using a Salmonella/microsome assay. Samples were extracted by sonication, sequentially, with cyclohexane (CX, and dichloromethane (DCM, for a rough fractionation by polarity. The different fractions were tested for mutagenicity using Salmonella typhimurium strains TA98, with and without metabolic activation (S9 mix fraction, and TA98NR and TA98/1,8-DNP6, without metabolic activation. Mutagenic response was observed for frameshift strain TA98 in assays with and without metabolization for two sites (sites 2 and 3, which had considerable risk of environmental contamination by nonpolar (CX and/or moderately polar (DCM compounds. However, the values of revertants/m3 (rev/m3 were highest on the site subject to automobile exhaust (site 3 in assays without (9.56 rev/m3 and with metabolization (5.08 rev/m3. Maximum mutagenic activity was detected in the moderately polar fraction, decreasing after metabolization. Nevertheless, the nonpolar fractions (CX gave higher mutagenic activity in the presence of metabolization than in the absence of the S9 mix fraction. The responses observed for TA98NR and TA98/1,8-DNP6 strains suggest the activity of nitrocompounds.Foi investigada a atividade mutagênica de material particulado de amostras de ar coletadas em três diferentes locais dentro da área urbana da cidade de Porto Alegre, Brasil, através do ensaio Salmonella/microssoma.

    In machine learning and statistics, probabilistic inference involving multimodal distributions is quite difficult. This is especially true in high dimensional problems, where most existing algorithms cannot easily move from one mode to another. To address this issue, we propose a novel Bayesian inference approach based on Markov Chain Monte Carlo. Our method can effectively sample from multimodal distributions, especially when the dimension is high and the modes are isolated. To this end, it exploits and modifies the Riemannian geometric properties of the target distribution to create wormholes connecting modes in order to facilitate moving between them. Further, our proposed method uses the regeneration technique in order to adapt the algorithm by identifying new modes and updating the network of wormholes without affecting the stationary distribution. To find new modes, as opposed to redis-covering those previously identified, we employ a novel mode searching algorithm that explores a residual energy function obtained by subtracting an approximate Gaussian mixture density (based on previously discovered modes) from the target density function.

    Full Text Available Abuse of the elderly is a form of violence to come to the public's attention. Dental professionals are in an ideal position to identify physical abuse. The aim of this study was to assess the prevalence of elderly abuse and analyze the database of injury reports that can be identified by dental teams. A documentary analysis study developed by the Elderly Protection Police Station of Porto Alegre, Rio Grande do Sul, was carried out. The information used came from 2,304 complaints filed at the aforementioned institution between the years of 2004 and 2006. The records of abuse are categorized as injury, neglect, mistreatment, theft, financial abuse, threat, disturbing the peace, atypical fact, and others. The injuries that could be identified by the dental team were classified according to the injury's location in the area of the head, face, mouth and neck. Descriptive analysis was performed, and chi-square tests were used to evaluate the distributions of the types of elder abuse in relation to sex and age. The most frequent of the different types of abuse was theft, with a prevalence of 17.8%, followed by disturbing the peace at 11.8%. Disturbing the peace, threat, and bodily injury were significantly associated with women. Elder abuse among women and men declines with age. The prevalence of head injury was 25% of the total injuries, most often in females, and in those aged < 70 years. Based on these results, it is necessary that the dental team observe the elderly person's appearance for suspicious physical signs.

    The Serra do Meio granite outcrops near the town of Campo Alegre de Lourdes, north-northeast of Bahia State. The granite is intrusive into micachists, which are correlatives of the Salgueiro-Cachoeirinha Group (Early Proterozoic), during early to the syn-tectonic shear phase. The geological setting also comprises a phosphatic rock-bearing carbonatitic complex and gabbroid complexes with one of the main world resources of Fe-Ti-V. The granite mineralogical composition grades from Aegerine-augite alkali-feldspar granite/syenites to Leuco alcali-feldspar granite. The geochemical analysis shows SiO 2 -enrichment (67 to 76%), in alkalis (Na 2 +K 2 O, 7,5 to 12,5%), Nb (up to 680ppm), Zr (up to 2,390ppm), Y (up to 250ppm) e REE (up to 796ppm). The geochemical behaviour is peculiar to alkaline series, denoting a silica-oversaturated, potassium-rich, magma. The chondrite-normalized REE patterns display a first group with smooth slopes from the La to Lu, and a second one with negative slopes. Negative Eu anomalies are displayed in all the patterns. The first group is HREE-enriched, with low fractionation ratios. Samples with milonytic fabrics and higher fractionation ratios are related to the second group, suggesting the interaction of metassomatic fluids and the alkaline magma. Discriminant diagrams for Nb, Y and Rb, coupled with geophysical data, point to an intrusive granite in an extensional within a plate tectonic setting of attenuated continental crust. (author) [pt

    Driving under the influence of multiple substances is a public health concern, but there is little epidemiological data about their combined use and putative impact on driving in low and middle-income countries where traffic crashes have been clustering in recent years. The aim of this study is to estimate the prevalence of alcohol and drug use - as well as their associated factors - among drivers in the context of alcohol outlets (AOs). A probability three-stage sample survey was conducted in Porto Alegre, Brazil. Individuals who were leaving AO were screened, with the selection of 683 drivers who met the inclusion criteria. Drivers answered a structured interview, were breathalyzed, and had their saliva collected for drug screening. Prevalences were assessed using domain estimation and logistic regression models assessed covariates associated with substance use. Benzodiazepines 3.9% (SE 2.13) and cocaine 3.8% (SE 1.3) were the most frequently detected drugs in saliva. Among drivers who were going to drive, 11% had at least one drug identified by the saliva drug screening, 0.4% two, and 0.1% three drugs in addition to alcohol. In multivariable analyses, having a blood alcohol concentration (BAC)>0.06% was found to be associated with a 3.64 times (CI 95% 1.79-7.39) higher chance of drug detection, compared with interviewees with lower BACs. To drive under the influence of multiple substances is likely to be found in this setting, highlighting an association between harmful patterns of consume of alcohol and the misuse of other substances.

  8. Advanced Multilevel Monte Carlo Methods

    KAUST Repository

    Jasra, Ajay

    2017-04-24

    This article reviews the application of advanced Monte Carlo techniques in the context of Multilevel Monte Carlo (MLMC). MLMC is a strategy employed to compute expectations which can be biased in some sense, for instance, by using the discretization of a associated probability law. The MLMC approach works with a hierarchy of biased approximations which become progressively more accurate and more expensive. Using a telescoping representation of the most accurate approximation, the method is able to reduce the computational cost for a given level of error versus i.i.d. sampling from this latter approximation. All of these ideas originated for cases where exact sampling from couples in the hierarchy is possible. This article considers the case where such exact sampling is not currently possible. We consider Markov chain Monte Carlo and sequential Monte Carlo methods which have been introduced in the literature and we describe different strategies which facilitate the application of MLMC within these methods.

    Maxwell Montes represent the most distinctive topography on the surface of Venus, rising some 11 km above mean planetary radius. The multiple data sets of the Pioneer missing and Earth based radar observations to characterize Maxwell Montes are analyzed. Maxwell Montes is a porkchop shaped feature located at the eastern end of Lakshmi Planum. The main massif trends about North 20 deg West for approximately 1000 km and the narrow handle extends several hundred km West South-West WSW from the north end of the main massif, descending down toward Lakshmi Planum. The main massif is rectilinear and approximately 500 km wide. The southern and northern edges of Maxwell Montes coincide with major topographic boundaries defining the edge of Ishtar Terra.

    Monte Carlo simulation is fast becoming a standard approach for many radiation applications that were previously treated almost entirely by experimental techniques. This is certainly true for Industrial Radiation and Radioisotope Measurement Applications - IRRMA. The reasons for this include: (1) the increased cost and inadequacy of experimentation for design and interpretation purposes; (2) the availability of low cost, large memory, and fast personal computers; and (3) the general availability of general purpose Monte Carlo codes that are increasingly user-friendly, efficient, and accurate. This paper discusses the history and present status of Monte Carlo simulation for IRRMA including the general purpose (GP) and specific purpose (SP) Monte Carlo codes and future needs - primarily from the experience of the authors

    Full Text Available A partir da emergência da ideia de sustentabilidade, a agricultura adquiriu novas conotações, associadas não apenas ao aspecto produtivo, mas também à conservação dos recursos naturais e dos territórios rurais, em um reconhecimento de sua multifuncionalidade. Com base nesta noção, que valoriza as funções socioambientais desempenhadas pelas famílias rurais e pelas agriculturas praticadas, o presente artigo analisa um assentamento rural no estado de São Paulo, buscando identificar quais são e de que forma se expressam as funções para além da produção neste território particular. Por meio de uma metodologia de cunho quali-quantitativo, observou-se que, no assentamento em foco, a agricultura encerra em si questões de coesão territorial, manutenção da segurança alimentar, conservação da agrobiodiversidade e de fomento a outras atividades produtivas, sendo o elemento central da reconstrução de um modo de vida rural neste ambiente.From the idea of sustainability, agriculture has acquired new connotations beyond the productive aspect, and associated with conservation of natural resources and rural territories, in recognition of their multiple functions. Based on this concept, which values the socioenvironmental functions performed by rural families, the present paper made an analysis on a rural settlement in the São Paulo state, aiming to identify functions beyond the production and their expression in this particular territory. With a methodology based on qualitative and quantitative information, it was observed that, in the settlement in focus, agriculture carries with it questions of territorial cohesion, maintenance of food security, agrobiodiversity conservation and the encouragement of other producing activities, being the central element of the rebuild of a rural way of life in this environment.

It was produced by the members of Student Federation From Porto Alegre - Feupa - during the 1940’s. This research indicates that the print production of students was culturally related at that time. The topics discussed by this group in the publication are diverse, among them politics, literature, philosophy, science, theater, and problems related to the university of Porto Alegre, which became later the federal university of Rio Grande do Sul. Trough Feupa, it is possible to perceive implicit political idead and positions when choosing the topics, the

  1. Adjoint electron Monte Carlo calculations

    1986-01-01

    Adjoint Monte Carlo is the most efficient method for accurate analysis of space systems exposed to natural and artificially enhanced electron environments. Recent adjoint calculations for isotropic electron environments include: comparative data for experimental measurements on electronics boxes; benchmark problem solutions for comparing total dose prediction methodologies; preliminary assessment of sectoring methods used during space system design; and total dose predictions on an electronics package. Adjoint Monte Carlo, forward Monte Carlo, and experiment are in excellent agreement for electron sources that simulate space environments. For electron space environments, adjoint Monte Carlo is clearly superior to forward Monte Carlo, requiring one to two orders of magnitude less computer time for relatively simple geometries. The solid-angle sectoring approximations used for routine design calculations can err by more than a factor of 2 on dose in simple shield geometries. For critical space systems exposed to severe electron environments, these potential sectoring errors demand the establishment of large design margins and/or verification of shield design by adjoint Monte Carlo/experiment

O consumo alimentar foi avaliado através do Inquérito Recordatório de 24 Horas e Investigação da História Dietética. Dos idosos entrevistados, 70% eram mulheres; 48,5% possuíam entre 60 e 69 anos; 68,8% possuíam menos de 8 anos de escolaridade; 39,0%, renda familiar entre 2 e 5 salários mínimos; e 58,4% não praticava exercício físico. A hipertensão foi a doença mais prevalente, e 54,9% dos idosos estavam abaixo do peso. Os homens consumiam mais calorias, proteínas, fibras, minerais e vitaminas do que as mulheres. O consumo de carboidrato e cálcio aumentou conforme o avanço da idade, assim como diminuiu a ingestão de zinco. A prática de exercício físico elevou o consumo de calorias, magnésio, potássio e fósforo. Quanto maior a escolaridade, maior é o consumo de vitaminas B6 e B12; quanto maior a renda familiar, maior o consumo de vitamina B6 e ácido fólico. Os resultados demonstram que há deficiências nutricionais na alimentação diária da nossa população de idosos, principalmente entre as mulheres e os indivíduos acima de 80 anos.

    Full Text Available Los odontomas son los tumores odontogénicos más comunes, casi siempre se diagnostican accidentalmente, en exámenes radiográficos; pueden sospecharse al retardar el brote dentario o producir maloclusiones. Se clasifican en odontomas compuestos y complejos, ambos constituidos por estructuras dentales como: esmalte, dentina, cemento y tejido pulpar. Su eliminación quirúrgica y la biopsia es el tratamiento de elección. El propósito de este trabajo es reportar tres casos de pacientes atendidos en el Hospital Pediátrico de Las Tunas, todos remitidos previamente por el ortodoncista. El primero, tipo compuesto, en un escolar de 9 años de edad, masculino, asociado a un 31 retenido; el segundo caso se trata de un gran odontoma complejo en una escolar de 11 años de edad, femenina, que produjo interferencia en el brote del 11 y el tercero compuesto; en un escolar de 10 años, masculino, en la línea media entre 11 y 21, con producción de diastema y brote del 12 por palatino. De ellos uno fue descubierto por un examen radiográfico de rutina y los otros dos sospechados por la maloclusión secundaria; todos se trataron quirúrgicamente. Estos casos demuestran la frecuencia de estos tumores en la cavidad bucal y la importancia de la realización de exámenes clínicos y radiográficos para su detección y tratamiento precoz, así como la importancia de la interrelación entre el ortodoncista y el maxilofacial en la resolución satisfactoria de esta entidad

  16. Multilevel sequential Monte Carlo samplers

    KAUST Repository

    Beskos, Alexandros

    2016-08-29

    In this article we consider the approximation of expectations w.r.t. probability distributions associated to the solution of partial differential equations (PDEs); this scenario appears routinely in Bayesian inverse problems. In practice, one often has to solve the associated PDE numerically, using, for instance finite element methods which depend on the step-size level . hL. In addition, the expectation cannot be computed analytically and one often resorts to Monte Carlo methods. In the context of this problem, it is known that the introduction of the multilevel Monte Carlo (MLMC) method can reduce the amount of computational effort to estimate expectations, for a given level of error. This is achieved via a telescoping identity associated to a Monte Carlo approximation of a sequence of probability distributions with discretization levels . ∞>h0>h1⋯>hL. In many practical problems of interest, one cannot achieve an i.i.d. sampling of the associated sequence and a sequential Monte Carlo (SMC) version of the MLMC method is introduced to deal with this problem. It is shown that under appropriate assumptions, the attractive property of a reduction of the amount of computational effort to estimate expectations, for a given level of error, can be maintained within the SMC context. That is, relative to exact sampling and Monte Carlo for the distribution at the finest level . hL. The approach is numerically illustrated on a Bayesian inverse problem. © 2016 Elsevier B.V.

    Full Text Available Generally, natural environments have been transformed into small forest remnants, with the consequent habitat loss and species extinction. The North Paraná State is not an exception, since only 2 to 4% of the original ecosystem occurs in small fragments of Stational Semidecidual Forest. We studied the species richness and abundance of bats in two forest fragments from the Fazenda Congonhas, in Rancho Alegre city, Paraná State, Brazil. Four samplings were undertaken in a legally protected native area (107.8ha and in a reforested area (11.8ha between April 2007 and March 2008. Samplings began at nightfall and lasted six hours, during two consecutive nights in each location. The individuals were captured using eight mist nets, with the same capture effort in both environments. A total of 397 individuals, 14 species and 10 genera were captured in the native area; while in the reforested area, 105 individuals, six species and four genera. Artibeus lituratus was the most common species in both fragments (n=328, 65.3%, followed by Artibeus fimbriatus (n=44, 8.8% and Artibeus jamaicensis (n=30, 6.0%. Other species including Platyrrhinus lineatus, Carollia perspicillata, Sturnira lilium, Chrotopterus auritus, Desmodus rotundus, Michronycteris megalotis, Phyllostomus hastatus, Phyllostomus discolor, Myoti levis, Myotis nigricans and Lasiurus blossevillii, accounted for 19.9% of the captures. The native area presented higher values of species richness (S=14 and diversity (H’=1.4802 in comparison to the reforested area (S=6, H’=0.57015. The t-test evidenced a significant difference between diversity among the sites (t=7.1075. Chao 1 index indicated that the sampling effort recorded approximately 78% from the total species richness for the native area and 75% for the reforested area. Therefore, the preservation of the forest fragment is essential since it provides habitat for a diverse community of bats. Forest management and reforestation actions may

    Leonardo Rossi

    Carlo Caso (1940 - 2007) Our friend and colleague Carlo Caso passed away on July 7th, after several months of courageous fight against cancer. Carlo spent most of his scientific career at CERN, taking an active part in the experimental programme of the laboratory. His long and fruitful involvement in particle physics started in the sixties, in the Genoa group led by G. Tomasini. He then made several experiments using the CERN liquid hydrogen bubble chambers -first the 2000HBC and later BEBC- to study various facets of the production and decay of meson and baryon resonances. He later made his own group and joined the NA27 Collaboration to exploit the EHS Spectrometer with a rapid cycling bubble chamber as vertex detector. Amongst their many achievements, they were the first to measure, with excellent precision, the lifetime of the charmed D mesons. At the start of the LEP era, Carlo and his group moved to the DELPHI experiment, participating in the construction and running of the HPC electromagnetic c...

    Full Text Available A preliminary survey was conducted for the presence of helminths in the city of Montes Claros, M. G., Brazil. Three groups of persons were examined by the direct smear, Kato thick film and MIFC techniques; one group by direct smear and Kato only. General findings were: a high prevalence of hookworm, followed by ascariasis, S. mansoni, S. stercoralis and very light infections with T. trichiurá. E. vermicularis and H. nana were ranking parasites at an orphanage, with some hookworm and S. mansoni infections as well. At a pig slaughter house, the dominant parasites were hookworm and S. mansoni. Pig cysticercosis was an incidental finding worth mentioning for the health hazard it represents for humans as well as an economic loss. From the comparative results between the Kato and the MIF the former proved itself again as a more sensitive and reliable concentration method for helminth eggs, of low cost and easy performance.Um estudo preliminar sobre helmintos foi feito na cidade de Montes Claros, MG, Brasil. Três grupos de pessoas foram examinados pelos métodos direto, de Kato e do MIF e um grupo pelos métodos direto e Kato exclusivamente. Encontrou-se uma alta prevalência de necatorose, seguindo-se ascaríase, S. mansoni, S. stercoralis, e infecções leves pelo T. trichiura. E. vermicularis e H. nana foram osparasitos mais prevalentes num orfanato, com alguns casos de infecção pelo Necator e S. mansoni. Cisticercose dos suinos foi achado incidental e é importante ser mencionada devido ao perigo que representa no plano da Saúde Pública, bem como pela perda econômica que produz. Discutiu-se brevemente a importância do solo na transmissão dos helmintos num clima quente e seco. Da comparação dos métodos de Kato e MIF, o primeiro demonstrou ser o método mais sensível para ovos de helmintos, de baixo custo e fácil preparo.

    Full Text Available Introdução: O estudo descreve uma amostra de usuários de droga injetável (UDI que buscam atendimento na cidade de Porto Alegre, a fim de conhecer melhor os métodos de exposição ao vírus HIV, gerando hipóteses para estudos futuros e diretrizes para programas preventivos. Métodos: Foram entrevistados 142 UDI, utilizando uma entrevista estruturada para levantamento de fatores de risco. Foram analisadas características demográficas e das relações sexuais, utilizando-se como desfechos de interesse o status sorológico e as características do uso de drogas, tais como freqüência e tipo de droga utilizada. Resultados: 97% dos indivíduos havia injetado cocaína (8,6 dias do mês, 9,3 vezes por dia e usado álcool e maconha no mês prévio à entrevista; apenas 44 apresentavam testes HIV (54,5% soropositivos. Quase 90% haviam recebido aconselhamento para HIV, porém a mudança de condutas aconteceu somente numa parcela dos casos, sem informação adequada sobre limpeza de seringas; 53% dos indivíduos relataram compartilhamento de equipamento prévio à coleta de dados, utilizando 16,2 vezes a mesma seringa. Os entrevistados eram sexualmente ativos e predominantemente heterossexuais, com uma média de sete relações por mês; 44% não usou camisinha nas relações sexuais e 48% afirmou ter utilizado pelo menos álcool antes ou durante as relações. Conclusões: Os achados sugerem que o aconselhamento é importante para modificar hábitos dos UDI mas não contempla necessidades de usuários recreacionais. A limpeza de seringas é infreqüente, talvez produto da pouca informação sobre práticas de risco. Os UDI são sexualmente ativos, heterossexuais e na maioria têm poucos parceiros, o que pode justificar o baixo uso de preservativos nessa amostra. É possível que o uso freqüente de drogas antes ou durante as relações contribua para tal fato.Introduction: This paper presents data on a sample of inner city injection drug users

  12. Is Monte Carlo embarrassingly parallel?

    International Nuclear Information System (INIS)

    Hoogenboom, J. E.

    2012-01-01

    Monte Carlo is often stated as being embarrassingly parallel. However, running a Monte Carlo calculation, especially a reactor criticality calculation, in parallel using tens of processors shows a serious limitation in speedup and the execution time may even increase beyond a certain number of processors. In this paper the main causes of the loss of efficiency when using many processors are analyzed using a simple Monte Carlo program for criticality. The basic mechanism for parallel execution is MPI. One of the bottlenecks turn out to be the rendez-vous points in the parallel calculation used for synchronization and exchange of data between processors. This happens at least at the end of each cycle for fission source generation in order to collect the full fission source distribution for the next cycle and to estimate the effective multiplication factor, which is not only part of the requested results, but also input to the next cycle for population control. Basic improvements to overcome this limitation are suggested and tested. Also other time losses in the parallel calculation are identified. Moreover, the threading mechanism, which allows the parallel execution of tasks based on shared memory using OpenMP, is analyzed in detail. Recommendations are given to get the maximum efficiency out of a parallel Monte Carlo calculation. (authors)

    Full Text Available Obesity is a condition characterized by excessive accumulation of body fat. In humans, this condition has shown fast and worrying growth, like in pets. This study aimed to establish the prevalence of obese cats living in Alegre, Espírito Santo, Brazil and its association with risk factors. Spearman correlation and chi-square test were used, considering a significance level of 5%. The prevalence of overweight or obesity was 14% in the studied population of 50 cats. Neutered and male cats were considered a risk factor for the development of obesity, unlike physical activity, considered as a protective factor. No correlation was found between the frequency or type of food provided and obesity. O acúmulo excessivo de gordura corpórea é a condição que caracteriza a obesidade. Esta condição na espécie humana vem mostrando um crescimento acelerado e preocupante, se fazendo da mesma forma em animais de companhia. Neste trabalho, objetivou-se estabelecer a prevalência de gatos obesos domiciliados no município de Alegre – Espírito Santo e sua associação com fatores de risco. Utilizou-se o método de correlação de Spearman e o teste do Qui-quadrado, considerando um nível de significância de 5%. A prevalência de obesidade ou sobrepeso foi de 14% na população estudada de 50 gatos domiciliados. Gatos machos e castrados foram considerados como fatores de risco para o desenvolvimento da obesidade, ao contrário da prática de atividade física, considerada como um fator protetor. Não houve correlação entre a frequência ou o tipo de alimento fornecido e o desenvolvimento da obesidade.

  16. Monte Carlo - Advances and Challenges

    2008-01-01

    Abstract only, full text follows: With ever-faster computers and mature Monte Carlo production codes, there has been tremendous growth in the application of Monte Carlo methods to the analysis of reactor physics and reactor systems. In the past, Monte Carlo methods were used primarily for calculating k eff of a critical system. More recently, Monte Carlo methods have been increasingly used for determining reactor power distributions and many design parameters, such as β eff , l eff , τ, reactivity coefficients, Doppler defect, dominance ratio, etc. These advanced applications of Monte Carlo methods are now becoming common, not just feasible, but bring new challenges to both developers and users: Convergence of 3D power distributions must be assured; confidence interval bias must be eliminated; iterated fission probabilities are required, rather than single-generation probabilities; temperature effects including Doppler and feedback must be represented; isotopic depletion and fission product buildup must be modeled. This workshop focuses on recent advances in Monte Carlo methods and their application to reactor physics problems, and on the resulting challenges faced by code developers and users. The workshop is partly tutorial, partly a review of the current state-of-the-art, and partly a discussion of future work that is needed. It should benefit both novice and expert Monte Carlo developers and users. In each of the topic areas, we provide an overview of needs, perspective on past and current methods, a review of recent work, and discussion of further research and capabilities that are required. Electronic copies of all workshop presentations and material will be available. The workshop is structured as 2 morning and 2 afternoon segments: - Criticality Calculations I - convergence diagnostics, acceleration methods, confidence intervals, and the iterated fission probability, - Criticality Calculations II - reactor kinetics parameters, dominance ratio, temperature

    Full Text Available Within education, co-production has been steadily gaining ground. It is characterized by an educational model that provides more interaction and shared responsibility. In other words, teachers develop lessons that motivate students to produce their activities and facilitate that process. In this context, active collaboration, dialogue, interaction, mutual responsibility and reflection are intrinsic aspects of learning and can help to reduce the negative impact of failures that occur in the services. In order to explore this theme empirically, descriptive research was conducted with 308 students from a management course at a private university, in Porto Alegre. The research was based on a similar investigation by Sierra (2009. The results show that shared responsibility is a crucial component in students’ learning, as well as in their experience of business education, because of its determining influence over their objective, subjective, cognitive and emotional assessments.

    In the present study, molecular detection of human adenoviruses (HAdV) and enteroviruses (EV) was performed in surface water samples collected from beaches Ipanema and Lami, located on the shores of Lake Guaíba, city of Porto Alegre, RS, southern Brazil. Furthermore, water safety was evaluated by counting thermotolerant coliforms (TC), following local government regulations. A total of 36 samples were collected monthly from six different sites along the beaches. Viral genomes were found in 30 (83.3%) samples. The higher detection rate was observed for HAdV (77.8%), followed by EV (22.2%). Although low concentrations of TC have been found, the occurrence of viral genomes in water samples was frequent and may pose a potential risk of infection for people bathing in these beaches.

    Full Text Available Creative economy has been the subject of a recent and successful academic production of different specialties in different countries, recording social, political and cultural changes involved in it. This article addresses the sense of the changes, recognized in international experience, in our context, centrally inquiring about: what kind of social implications takes place due to the growth of activities in companies in the sectors of creative economy? It starts from the recognition that economic action finds itself immersed in a set of mechanisms of social mediation. Data were obtained on a purposeful sample of fourteen small enterprises belonging to this economy in the city of Porto Alegre, complementing with documentary sources. The study suggests that this type of business tends to be guided by the pursuit of novelty, complementarity of knowledge, professional autonomy and responsibility with the environment, within the limits of the social and institutional conditions in which they take part.

    We review quantum Monte Carlo methods for dealing with large shell model problems. These methods reduce the imaginary-time many-body evolution operator to a coherent superposition of one-body evolutions in fluctuating one-body fields; resultant path integral is evaluated stochastically. We first discuss the motivation, formalism, and implementation of such Shell Model Monte Carlo methods. There then follows a sampler of results and insights obtained from a number of applications. These include the ground state and thermal properties of pf-shell nuclei, thermal behavior of γ-soft nuclei, and calculation of double beta-decay matrix elements. Finally, prospects for further progress in such calculations are discussed. 87 refs

    Monte Carlo methods appropriate to simulate the transport of x-rays, neutrons, ions and electrons in Inertial Confinement Fusion targets are described and analyzed. The Implicit Monte Carlo method of x-ray transport handles symmetry within indirect drive ICF hohlraums well, but can be improved 50X in efficiency by angular biasing the x-rays towards the fuel capsule. Accurate simulation of thermonuclear burn and burn diagnostics involves detailed particle source spectra, charged particle ranges, inflight reaction kinematics, corrections for bulk and thermal Doppler effects and variance reduction to obtain adequate statistics for rare events. It is found that the effects of angular Coulomb scattering must be included in models of charged particle transport through heterogeneous materials.

    Monte Carlo methods appropriate to simulate the transport of x-rays, neutrons, ions and electrons in Inertial Confinement Fusion targets are described and analyzed. The Implicit Monte Carlo method of x-ray transport handles symmetry within indirect drive ICF hohlraums well, but can be improved 50X in efficiency by angular biasing the x-rays towards the fuel capsule. Accurate simulation of thermonuclear burn and burn diagnostics involves detailed particle source spectra, charged particle ranges, inflight reaction kinematics, corrections for bulk and thermal Doppler effects and variance reduction to obtain adequate statistics for rare events. It is found that the effects of angular Coulomb scattering must be included in models of charged particle transport through heterogeneous materials

    This work generalizes a multilevel forward Euler Monte Carlo method introduced in Michael B. Giles. (Michael Giles. Oper. Res. 56(3):607–617, 2008.) for the approximation of expected values depending on the solution to an Itô stochastic differential equation. The work (Michael Giles. Oper. Res. 56(3):607– 617, 2008.) proposed and analyzed a forward Euler multilevelMonte Carlo method based on a hierarchy of uniform time discretizations and control variates to reduce the computational effort required by a standard, single level, Forward Euler Monte Carlo method. This work introduces an adaptive hierarchy of non uniform time discretizations, generated by an adaptive algorithmintroduced in (AnnaDzougoutov et al. Raùl Tempone. Adaptive Monte Carlo algorithms for stopped diffusion. In Multiscale methods in science and engineering, volume 44 of Lect. Notes Comput. Sci. Eng., pages 59–88. Springer, Berlin, 2005; Kyoung-Sook Moon et al. Stoch. Anal. Appl. 23(3):511–558, 2005; Kyoung-Sook Moon et al. An adaptive algorithm for ordinary, stochastic and partial differential equations. In Recent advances in adaptive computation, volume 383 of Contemp. Math., pages 325–343. Amer. Math. Soc., Providence, RI, 2005.). This form of the adaptive algorithm generates stochastic, path dependent, time steps and is based on a posteriori error expansions first developed in (Anders Szepessy et al. Comm. Pure Appl. Math. 54(10):1169– 1214, 2001). Our numerical results for a stopped diffusion problem, exhibit savings in the computational cost to achieve an accuracy of ϑ(TOL),from(TOL−3), from using a single level version of the adaptive algorithm to ϑ(((TOL−1)log(TOL))2).

    The issues affecting implementation of parallel algorithms for large-scale engineering Monte Carlo neutron transport simulations are discussed. For nuclear reactor calculations, these include load balancing, recoding effort, reproducibility, domain decomposition techniques, I/O minimization, and strategies for different parallel architectures. Two codes were parallelized and tested for performance. The architectures employed include SIMD, MIMD-distributed memory, and workstation network with uneven interactive load. Speedups linear with the number of nodes were achieved

La dicotomía entre la jurisdicción extraterritorial, con la jurisdicción territorial chilena, es resuelta al no acceder el Ministro del Interior británico, Jack Straw, a conceder la extradición del General Augusto Pinochet a España, por motivos humanitarios, regresando éste a Chile para ser juzgado por su juez natural una vez levantada su inmunidad. Se le acusa de ser autor intelectual y coautor de supuestos delitos, de 18 secuestros y 57 homicidios, perpetrados por la llamada "caravana de la muerte", una comitiva militar que recorrió el país en 1973, exterminando opositores al régimen de Pinochet, quien ha quedado bajo arresto domiciliario tras habérsele efectuado exámenes mentales y tomada su declaración indagatoria por el juez Juan Guzmán.

De maneira geral, os agregados da parcela "milho" apresentaram os mais baixos níveis de elementos. Pequenas diferenças apresentaram as duas parcelas - "pomar" e "eucalipto". A soma das bases trocáveis e a capacidade de troca de cations parecem estar intimamente relacionadas com os valores de matéria orgânica, mostrando a importância dêsse constituinte do solo.An attempt was made to analyse the physico-chemical characteristics of soil sample aggregates proceeding from three different areas: corn growing-plots, orchards of fruits of temperate climate and eucalyptus groves. In the laboratory the following determinations were carried out: granulometric, pH, C and N totais, Ca++, Mg++ and K+ exchangeable and capacity of cation exchange. The variation of element contents was not very large in the different classes of size of the aggregates of the analysed soils. Ina general way, the aggregates of the "corn" area presented the lowest levels of the analysed elements whereas the other two, "orchards and encalyptus plots", showed quite immaterial differences. The sum of exchangeable bases and the capacity for cation exchange seems to be intimately related to the values of organic matter, thus showing the importance of this soil constituent.

    Letícia Squeff

    Full Text Available Resumo Manuel de Araújo Porto-Alegre (1806-1879 foi um dos mais importantes pensadores do século XIX no Brasil. Este artigo trata da importância que a viagem para a Itália teve na trajetória deste pensador. Os contatos com os clássicos e com o universo das viagens pitorescas marcaram a sua produção como artista. Nos poucos desenhos daquele período que chegaram até nós, percebe-se o gosto pelo pitoresco de um artista sintonizado com a cultura do Grand Tour e com a sensibilidade romântica. Além disso, o aprendizado na Itália familiarizou o brasileiro com valores e métodos em discussão nos meios antiquários e eruditos da época. Graças a isso, Porto-Alegre faria alguns anos depois uma interpretação da história da arte no Brasil inspirada na leitura de autores como Johann J. Winckelmann e Luigi Lanzi. Finalmente, o artigo defende que a passagem pela Itália funcionou, para Porto-Alegre, como uma espécie de atestado simbólico, garantindo- lhe lugar entre os eruditos franceses do Instituto Histórico de Paris, bem como entre os estudiosos do Instituto Histórico Brasileiro. Se fora para a Europa como aspirante a pintor, Porto-Alegre voltou da Itália como um erudito.

    Full Text Available O ciclismo é um esporte de origem europeia, que pode ser definido como a prática das corridas de bicicleta. No decorrer do século XIX ocorreu sua difusão para outros continentes, chegando ao Brasil e ao estado do Rio Grande do Sul na segunda metade do século. Objetivo: historiar desde as primeiras provas ciclísticas em Porto Alegre, passando pelo arrefecimento das disputas, até os anos de 1930, quando são retomadas as provas ciclísticas na cidade. Método: análise documental de publicações acerca do ciclismo em jornais do Rio Grande do Sul que circulavam na transição do século XIX e primeira metade do século XX. Resultados e Discussão: no princípio, a prática ciclística era promovida por dois clubes de Porto Alegre, que rivalizavam disputas acirradas. Ambos possuíam locais próprios para a prática, os velódromos. No final da década de 1910, o ciclismo teve um declínio com o advento do futebol, a novidade esportiva da época. Após um período em baixa, o esporte ganha um novo fôlego na década de 1930. Novos clubes haviam sido formados e a prática não estava mais restrita à capital, ocorriam também no interior, principalmente na cidade de Pelotas. A partir do fim do século XIX, as competições passaram a ter notas frequentes no jornal A Federação. Além disso, houve a criação de uma entidade própria, a Federação Gaúcha de Ciclismo, em 1935, que, posteriormente, também incorporou a prática do motociclismo. Considerações finais: historicamente, o ciclismo faz parte do cenário esportivo sul-rio-grandense, mas, ao longo do tempo, sofreu períodos de ascensão e declínio nas primeiras décadas do século XX.

    Full Text Available The geochemical characterization of thirteen Serra Geral Group flows in the Vista Alegre region (RS-SC, southern Brazil, displays the homogeneous basaltic composition near 50 wt.% SiO2. Each of the five basal flows (Pitanga-type, high-Ti/Y ~600, TiO2 > 3 wt.% and eight upper flows (Paranapanema-type, medium Ti/Y ~400, TiO2 > 2 wt.% can be identified from their chemical composition; sets of flows have parallel variation in chemical composition. The flow-by-flowcorrelation in four sections shows the horizontal position of the flows in three profiles and an approximately 200-m downdrop of the Itapiranga block with respect to the Frederico Westphalen block. The world-class amethyst geode mineralization and the systematic presence of native copper in the basalts make the correlation of great geological and economic significance.A caracterização geoquímica de treze derrames do Grupo Serra Geral na região de Vista Alegre (RS e SC, sul do Brasil, exibe uma composição basáltica homogênea próxima a 50% de SiO2.

Cada derrame pode ser identificado através de sua composição química e correlacionado, com variação paralela entre os perfis estudados. A correlação derrame a derrame nos quatro perfis demonstra uma posição horizontal em três perfis e um rejeito vertical de aproximadamente 200 m do bloco Itapiranga em relação ao bloco Frederico Westphalen. A presença de jazidas de ametista em geodos e a sistemática ocorrência de cobre nativo nos basaltos da região tornam a correlação de grande significado geológico e econômico.

    For this paper, we employ the Monte Carlo scene (MCScene) radiative transfer code to elucidate the underlying physics giving rise to the structure and colors of the antitwilight, i.e., twilight opposite the Sun. MCScene calculations successfully reproduce colors and spatial features observed in videos and still photos of the antitwilight taken under clear, aerosol-free sky conditions. Through simulations, we examine the effects of solar elevation angle, Rayleigh scattering, molecular absorption, aerosol scattering, multiple scattering, and surface reflectance on the appearance of the antitwilight. We also compare MCScene calculations with predictions made by the MODTRAN radiative transfer code for a solar elevation angle of +1°.

    Modern cancer treatment relies on Monte Carlo simulations to help radiotherapists and clinical physicists better understand and compute radiation dose from imaging devices as well as exploit four-dimensional imaging data. With Monte Carlo-based treatment planning tools now available from commercial vendors, a complete transition to Monte Carlo-based dose calculation methods in radiotherapy could likely take place in the next decade. Monte Carlo Techniques in Radiation Therapy explores the use of Monte Carlo methods for modeling various features of internal and external radiation sources, including light ion beams. The book-the first of its kind-addresses applications of the Monte Carlo particle transport simulation technique in radiation therapy, mainly focusing on external beam radiotherapy and brachytherapy. It presents the mathematical and technical aspects of the methods in particle transport simulations. The book also discusses the modeling of medical linacs and other irradiation devices; issues specific...

    A Monte Carlo simulation is an important computational tool used in many areas of science and engineering. The use of Monte Carlo techniques for simulating neutron scattering instruments is discussed. The basic ideas, techniques and approximations are presented. Since the construction of a neutron scattering instrument is very expensive, Monte Carlo software used for design of instruments have to be validated and tested extensively. The McStas software was designed with these aspects in mind and some of the basic principles of the McStas software will be discussed. Finally, some future prospects are discussed for using Monte Carlo simulations in optimizing neutron scattering experiments. (R.P.)

  2. Status of Monte Carlo dose planning

    1995-01-01

    Monte Carlo simulation will become increasing important for treatment planning for radiotherapy. The EGS4 Monte Carlo system, a general particle transport system, has been used most often for simulation tasks in radiotherapy although ETRAN/ITS and MCNP have also been used. Monte Carlo treatment planning requires that the beam characteristics such as the energy spectrum and angular distribution of particles emerging from clinical accelerators be accurately represented. An EGS4 Monte Carlo code, called BEAM, was developed by the OMEGA Project (a collaboration between the University of Wisconsin and the National Research Council of Canada) to transport particles through linear accelerator heads. This information was used as input to simulate the passage of particles through CT-based representations of phantoms or patients using both an EGS4 code (DOSXYZ) and the macro Monte Carlo (MMC) method. Monte Carlo computed 3-D electron beam dose distributions compare well to measurements obtained in simple and complex heterogeneous phantoms. The present drawback with most Monte Carlo codes is that simulation times are slower than most non-stochastic dose computation algorithms. This is especially true for photon dose planning. In the future dedicated Monte Carlo treatment planning systems like Peregrine (from Lawrence Livermore National Laboratory), which will be capable of computing the dose from all beam types, or the Macro Monte Carlo (MMC) system, which is an order of magnitude faster than other algorithms, may dominate the field

    Full Text Available Objective: To verify the association between age and gender regarding HIV seropositivity in drug users who seek public health centers in Porto Alegre, Brazil. Methods: The authors designed a cross-sectional study with a convenience sampling of 695 men and women aged above 15, who reported recent drug use and risk behaviors to HIV exposure. We used a standard questionnaire (CRA, Brazilian version of the RAB, Risk Assessment Battery to assess risk behaviors and we collected blood for HIV testing. Results: Most individuals were males (75,8%, with a mean age of 29.4 years, less than seven years of schooling (42,4%, and family income equal or superior to four minimum wages (46%. There was no significant association between gender and seropositivity. Multivariate analyses showed that individuals aged above 30 had a three-fold increased odds of being seropositive over subjects aged 20 or less. Intravenous drug users who had been using drugs since 1980 had five-fold odds of seropositivity and those who had been using them in the month prior to the interview had four-fold odds. Discussion: Subjects aged more than 30 showed higher odds of seropositivity than the younger group. This is possibly due to a higher use of intravenous cocaine and to having more risk behaviors along their lifetime. There was no difference in seropositivity between genders, what differs from current data of other studies, if we take into consideration that rates of populational seropositivity among women have increased, mostly among drug users, who are, therefore, at 'double risk'. The development of further studies is mandatory in order to assess gender and age as risk factors for seropositivity, whether to confirm or to deny these findings, and to plan specific strategies for high-risk groups.Objetivo: Verificar se idade e gênero estão relacionados à soropositividade para HIV em usuários de drogas que procuram centros de atendimento em saúde de Porto Alegre.

    Full Text Available Resumo: Feminicídios são assassinatos de mulheres decorrentes das desigualdades de gênero e representam a forma mais extrema da violência contra a mulher. O referencial teórico-metodológico utilizado neste estudo foi a teoria do patriarcado e a análise crítica do discurso. Foram analisados os discursos referentes ao relatório final de 64 inquéritos policiais categorizados como feminicídios, ocorridos na cidade de Porto Alegre, Rio Grande do Sul, Brasil, no período de 2006 a 2010. As vítimas eram majoritariamente mulheres pobres, jovens e moradoras de regiões de periferia, havendo uma frequência elevada de prostitutas e mulheres executadas pelo tráfico; mortes não consideradas feminicídios pelos operadores policiais. Muitos inquéritos foram arquivados devido à ausência de provas e outros não foram nem ao menos iniciados. Nos inquéritos, havia discursos que desqualificavam e culpavam as vítimas, embora alguns criticassem as desigualdades entre homens e mulheres e identificassem os efeitos letais do machismo. Inquéritos policiais são fontes importantes para estudar o feminicídio na sociedade, agregando grande quantidade de informações sobre vítimas, agressores e cenários dos crimes.

    Efforts have been made in Brazil to improve the thermal performance of low-cost buildings. Since 1997 studies on low-cost housing have been developed by Nucleo Orientado para a Inovacao da Edificacao, the construction sector of the Engineering College of the Rio Grande do Sul University, Brazil. In 2000 a prototype of a low-cost house was built on the university campus. This prototype has undergone several evaluations in an attempt to assess its thermal and environmental performance, like: energy consumption, rainwater harvesting, use of sustainably managed wood for window frames and doors, besides a detailed accounting of overall costs. The thermal performance of the house was monitored, by recording outdoor and indoor air temperatures and relative humidity, over the period of whole year. A brief appraisal of such results, as well as the annual heating and cooling degree-hours are presented. Daily swings in outdoor are a common climatic event in Porto Alegre and the building response to daily temperature swings, greater than 10 K, and hot and cold spells are presented. The results show that the thermal performance of the prototype is fairly satisfactory, considering the limitations of a low-cost house, when artificial heating and cooling is not affordable.

    Recent policies adopted in Cuba are producing a significant turn into the country's socioeconomic dynamics. Past shifting circumstances have demonstrated the positive and negative implications on heritage sites. In this regard, this paper presents a first stage of a research project aimed at monitoring the impact of socioeconomic dynamics on local heritage sites. The research partial results focus on the documentation of the evolution of a case study: Vista Alegre District in the city of Santiago de Cuba. Scholars have noted that the District's urban design and historic building stock represent its most significant heritage values. Such qualities are under permanent threat due to transformations and deterioration. In order to analyse current site condition, and to understand transformations as a result of socioeconomic dynamics, a Geographic Information System (GIS) was implemented as a monitoring and documenting tool. The GIS allowed integrating data related to the evolution of the urban layout, and the heritage buildings. Data was sourced from heritage management and urban planning offices, as well as from previous studies on the site. In addition, the analysis of remote sensing imagery, and a field survey helped to update the existing records, and to include new information with the purpose of assessing the integrity of heritage values. At this stage, maps that describe the site evolution, the significant changes over time, and the alterations to character defining elements served to identify sectors of different scenic qualities. Results are essential to contribute to draft management strategies as part of decision making.

    An ecological study was conducted to analyze trends in hospitalization for primary care-sensitive conditions linking the results to the investments in health and coverage of the Family Health Strategy in Porto Alegre, between 1998 and 2012. The causes of hospitalization for primary care-sensitive conditions were based on the national list provided by the Ministry of Health. The data were obtained from the Hospital Information System of the Unified Health System (SUS). Standardized rates were created and investments increased by 27%, though investments in primary care increased by 83%. The expansion of coverage by the Family Health Strategy was almost fourfold, though it remained below the recommended values. There was no change in the trend of hospitalization for primary care-sensitive conditions. The analysis did not make it possible to establish if patients who were hospitalized for primary care-sensitive conditions had access to the Family Health Strategy or not, suggesting the need to incorporate data of place of origin in the information system. Studies using the Hospital Information System contribute to its enhancement, fomenting the assessment, management and design of health policies.

  11. Appropriation and rationality in hip hop groups organization practices in Porto Alegre: an analysis on the perspective of Guerreiro Ramos

    Directory of Open Access Journals (Sweden)

    Guilherme Dornelas Camara

    Full Text Available This paper discusses the organizational practices of hip hop groups from Porto Alegre, southern Brazil, as they appropriate foreign experience and rationally guide their social action. The aim of this work is to investigate these practices, based on the formulations of Brazilian sociologist Alberto Guerreiro Ramos, as they are enunciated in the works The Sociological Reduction and The New Science of Organizations. This approach offers fruitful material to broaden the theory and may be subsidiary to this kind of socio-cultural study, explaining why it is pertinent in this field. In this sense, the hip hop movement can be viewed as valuable when it comes to understanding phenomena which, due to (and in spite of being originally transnational, or even "foreign", act or interact worldwide. Examining the organization practices and social action of these groups also helped identify a concern with the production of cultural artifacts that represent and form a symbolism that is historically and culturally located. Another issue that was broached concerns the market since for those groups it is not a category absent from their struggles and actions, but the economic criteria are incidental in relation to their members' motivation.

    2002-01-01

    Full Text Available The authors present a quantitative and qualitative study on homicides among teenagers in Porto Alegre, Rio Grande do Sul State, Brazil, based on a historical series during the 1990s and the life and death histories in this group, with a special focus on 1997. In that year there were 68 homicides in which the victims were from 10 to 19 years old. Of the 68, 62 were males and only 6 females, or a ratio of 10:1, showing that young males are more vulnerable and susceptible to being murdered. The data indicate that cause of death is influenced by gender culture and that homicides are based on power and status symbols characterizing a kind of virility. This expression of virility in the shaping of violence also appears in the domination of the female body observed in homicides with young women as the victims. The life and death histories of these teenagers highlight the pertinence of the gender-based analysis as a theoretical-analytical category, in addition to analyses considering socioeconomic aspects and social inequity.

    The objective of this study was to evaluate the presence of hygienic and sanitary indicator microorganisms in samples of food served in public schools in Porto Alegre. All the food served in the meal of the session visited was analyzed for Escherichia coli, coagulase-positive Staphylococcus, Salmonella sp. and Shigella sp. Of the total of 196 food products analyzed in 120 schools, 4 contained and Escherichia coli score above the permitted level, and 2 contained coagulase-positive Staphylococcus. Neither Shigella nor Salmonella genus were detected. In the majority of schools studied, it was found that food was of an adequate hygienic-sanitary standard. However, only municipal schools had the supervision of a technician responsible for school food. In the state schools, 60% had never been visited by a nutritionist and in these schools several procedures failed to comply with legal requirements. In most of the schools studied, the food served to students was within adequate standards, though the problems detected revealed the need for the implementation of Best Practices in the school environment.

    Full Text Available ABSTRACT This research investigates and interprets the construction of educational strategies by afro-descendents implemented by several afro organizations in Porto Alegre, RS, from the end of the XIX century, over the First Republic, the New State and the respective re-democratizing processes until the year 2002. Over this period, the afro organizations had different configurations according to their contexts, their forms of composition and their claims arise from the conditions or from their lack, coming from a broader society. Such organizations, either of religious nature, mutual aid, cultural or, under the current perspective, of non-governmental organizations, comprise a common feature that is translated into the preservation of the identity and into the claims for the establishment of fair survival conditions for the afro-descendents. Due to the absence of documentation of the historical-educational trajectory of the afro population in the official means of divulgation, statistics and in the traditional historiography, this investigation aims at registering this history through specific publications and reports from reference people, what allows recovering the performance profile of these organizations and setting the memory of what respects their constructions and historical and educational claims.

    Full Text Available Introduction: Renal cell carcinoma (RCC is an aggressive disease worldwide. Objective: Study traditional prognostic factors associated with pathological reports and the novel markers survivin and B7-H1 by immunohistochemistry. Methods: In a reference hospital of Porto Alegre, Brazil, we conducted a cross-sectional study of RCC in patients who underwent radical nephrectomy between 2006 and 2009. We selected those who were diagnosed with the most common histologic subtypes: clear cell and papillary RCC. We retrospectively reviewed pathological data to determine traditional prognostic factors, like size, presence of coagulative necrosis, Fuhrman grade and tumor-node metastasis (TNM system. Besides, we performed an immunohistochemistry (IHC study with survivin and B7-H1. Results: Our sample had 98 cases, 90% of the cases were composed by clear cell histologic subtype, 73% were tumors classified as T1 and T2 in the TNM system, most were Fuhrman nuclear grade 2 or 3, and 70% were positive for necrosis. In relation to the new prognostic markers, we found 50 cases positive to survivin and 38 to B7-H1. In this investigation of traditional prognostic markers and new markers we observed that only necrosis was associated with positive results of biomarkers. < 0.001. Conclusion: This finding confirms previous studies that necrosis is an important factor to consider in the prognosis of RCC.

    The Monte Carlo program KIM solves the steady-state linear neutron transport equation for a fixed-source problem or, by successive fixed-source runs, for the eigenvalue problem, in a two-dimensional thermal reactor lattice. Fluxes and reaction rates are the main quantities computed by the program, from which power distribution and few-group averaged cross sections are derived. The simulation ranges from 10 MeV to zero and includes anisotropic and inelastic scattering in the fast energy region, the epithermal Doppler broadening of the resonances of some nuclides, and the thermalization phenomenon by taking into account the thermal velocity distribution of some molecules. Besides the well known combinatorial geometry, the program allows complex configurations to be represented by a discrete set of points, an approach greatly improving calculation speed

O aumento das taxas de incidência pode ser devido a estratégias de detecção precoce do câncer, mudanças no estilo de vida das pessoas e a alterações da estrutura etária da população. Um perfil populacional semelhante ao de países desenvolvidos pode justificar as maiores taxas de incidência encontradas em Porto Alegre. Apesar disso, Fortaleza apresentou os maiores incrementos para o período.

    MC21 is a new Monte Carlo neutron and photon transport code currently under joint development at the Knolls Atomic Power Laboratory and the Bettis Atomic Power Laboratory. MC21 is the Monte Carlo transport kernel of the broader Common Monte Carlo Design Tool (CMCDT), which is also currently under development. The vision for CMCDT is to provide an automated, computer-aided modeling and post-processing environment integrated with a Monte Carlo solver that is optimized for reactor analysis. CMCDT represents a strategy to push the Monte Carlo method beyond its traditional role as a benchmarking tool or ''tool of last resort'' and into a dominant design role. This paper describes various aspects of the code, including the neutron physics and nuclear data treatments, the geometry representation, and the tally and depletion capabilities

    The Monte Carlo method allows for simulating random processes by using series of pseudo-random numbers. It became an important tool in nuclear medicine to assist in the design of new medical imaging devices, optimise their use and analyse their data. Presently, the sophistication of the simulation tools allows the introduction of Monte Carlo predictions in data correction and image reconstruction processes. The availability to simulate time dependent processes opens up new horizons for Monte Carlo simulation in nuclear medicine. In a near future, these developments will allow to tackle simultaneously imaging and dosimetry issues and soon, case system Monte Carlo simulations may become part of the nuclear medicine diagnostic process. This paper describes some Monte Carlo method basics and the sampling methods that were developed for it. It gives a referenced list of different simulation software used in nuclear medicine and enumerates some of their present and prospective applications. (author)

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex eco-socio-economic-technical systems which we must understand to design a secure future for the nation and the world. Perturbations/disruptions in CASoS have the potential for far-reaching effects due to highly-saturated interdependencies and allied vulnerabilities to cascades in associated systems. The Phoenix initiative approaches this high-impact problem space as engineers, devising interventions (problem solutions) that influence CASoS to achieve specific aspirations. CASoS embody the world's biggest problems and greatest opportunities: applications to real world problems are the driving force of our effort. We are developing engineering theory and practice together to create a discipline that is grounded in reality, extends our understanding of how CASoS behave, and allows us to better control those behaviors. Through application to real-world problems, Phoenix is evolving CASoS Engineering principles while growing a community of practice and the CASoS engineers to populate it.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex ecological, sociological, economic and/or technical systems which must be recognized and reckoned with to design a secure future for the nation and the world. Design within CASoS requires the fostering of a new discipline, CASoS Engineering, and the building of capability to support it. Towards this primary objective, we created the Phoenix Pilot as a crucible from which systemization of the new discipline could emerge. Using a wide range of applications, Phoenix has begun building both theoretical foundations and capability for: the integration of Applications to continuously build common understanding and capability; a Framework for defining problems, designing and testing solutions, and actualizing these solutions within the CASoS of interest; and an engineering Environment required for 'the doing' of CASoS Engineering. In a secondary objective, we applied CASoS Engineering principles to begin to build a foundation for design in context of Global CASoS

Em vista disso, realizou-se um estudo quantitativo, contemporâneo, observacional, realizado por meio da aplicação de um questioná- rio estruturado objetivando analisar a forma mais comum de descarte de medicamentos por usuários da Unidade de Saúde Parque dos Maias (USPM do Grupo Hospitalar Conceição (GHC, localizada no município de Porto Alegre/ RS. O estudo incluiu 238 moradores, com erro aceitável de 5% e um nível de confiança de 95%. Em relação à análise da população estudada observou-se que 97,9% relataram que possuem medicamentos em suas residências; 86,6% nunca receberam orientação de como descartar medicamentos; 60% descartam no meio ambiente os medicamentos vencidos encontrados nos domicílios. A investigação estatística realizada pelo teste de Qui-quadrado para as variáveis analisadas não apresentou associação estatisticamente significativa entre escolaridade e renda com boa parte das ações de descarte de medicamentos pesquisadas. Constatou-se que medidas efetivas deveriam ser melhor organizadas para diminuir e regulamentar a geração e o destino dos medicamentos impróprios para o consumo presentes nas residências, minimizando assim danos ao meio ambiente e a saúde pública.

    To investigate the relation of hospitalization for ambulatory care sensitive conditions (ACSC) with the quality of public primary care health services in Porto Alegre, Brazil. Cohort study constructed by probabilistic record linkage performed from August 2006 to December 2011 in a population ≥18 years of age that attended public primary care health services. The Primary Care Assessment Tool (PCATool-Brazil) was used for evaluation of primary care services. Of 1200 subjects followed, 84 were hospitalized for primary care sensitive conditions. The main causes of ACSC hospital admissions were cardiovascular (40.5%) and respiratory (16.2%) diseases. The PCATool average score was 5.3, a level considerably below that considered to represent quality care. After adjustment through Cox proportional hazard modelling for covariates, >60 years of age [hazard ratio (HR): 1.13; P = 0.001), lesser education (HR: 0.66; P = 0.02), ethnicity other than white (HR: 1.77; P = 0.01) and physical inactivity (HR: 1.65; P = 0.04) predicted hospitalization, but higher quality of primary health care did not. Better quality of health care services, in a setting of overwhelmingly low quality services not adapted to the care of chronic conditions, did not influence the rate of avoidable hospitalizations, while social and demographic characteristics, especially non-white ethnicity and lesser schooling, indicate that social inequities play a predominant role in health outcomes. © The Author 2015.

    To identify the factors associated with aging of the socially-active elderly in the metropolitan region of Porto Alegre. A cross-sectional study was conducted involving a sample of 400 elderly subjects. Through a conglomerate analysis using the combined results of the Flanagan Scale and the quality of life assessment instrument developed by the World Health Organization (WHOQOL-100), the subjects classified as presenting a higher quality of life were considered to have aged successfully. After having been adjusted for the variables gender, age, level of depression, despair, perceived health status, meaning that personal beliefs give to life, satisfaction with social activities and relations, the following factors maintained their independent and meaningful effect on successful aging: family relations and friendships (OR = 4.93; 95% CI: 2.83-8.60), health and perceived well being (OR = 1.66; 95% CI: 1.07-2.59), functional capacity (OR = 23.70; 95% CI: 10.98-51.06) and psychosocial support (OR = 7.36; 95% CI: 4.00-13.54). Independence in performing daily life activities and autonomy, as well as satisfaction with family relations and friendships, were independent predictive factors of successful aging for both men and women. For women in particular, there were various predictive factors: material comfort; feeling physically well; body image and appearance; self-esteem; positive feelings; interpersonal relationships; social support; participation in recreational activities; sexuality; spirituality; and beliefs. The elderly maintain a relationship with themselves, with others and with their beliefs. Family is the main social support system.

    Full Text Available INTRODUÇÃO: No Brasil, aproximadamente 19 mil pessoas adquiriram o vírus HIV por meio do uso de drogas injetáveis desde o início da epidemia, com a soroprevalência em amostras destes usuários variando entre 25% e 65%. O objetivo deste estudo é comparar os comportamentos de risco para infecção por HIV entre amostras de usuários de cocaína injetável do Rio de Janeiro e de Porto Alegre. MÉTODOS: Comparação entre dados de estudos transversais conduzidos em Porto Alegre e no Rio de Janeiro. Um grupo de 250 indivíduos que haviam utilizado cocaína injetável nos seis meses prévios à coleta respondeu ao RBA (Risk Behaviour Assessement e realizou testagem anti-HIV em ambos os centros. RESULTADOS: Não houve diferença estatisticamente significativa entre os dados demográficos, exceto entre as médias de idade (31 anos no Rio de Janeiro e 28 anos em Porto Alegre. Em Porto Alegre, houve maior uso de cocaína injetável e maior número de comportamentos de risco relacionados a este uso. No Rio de Janeiro, houve mais comportamentos sexuais de risco e uso mais freqüente de cocaína aspirada e álcool. DISCUSSÃO: Os usuários de cocaína injetável das duas regiões estudadas apresentavam freqüências diferentes nos comportamentos de risco para HIV, e estes comportamentos parecem estar relacionados com o tipo, a via e a freqüência das drogas utilizadas. Os dados foram coletados entre 1994 e 1997, quando o uso de crack era menor nestas cidades, o que pode ter alterado o padrão atual de comportamentos de risco para HIV em usuários de cocaína.INTRODUCTION: In Brazil, about 19.000 of HIV cases have been attributed to injection drug use, with the seroprevalence among such samples ranging from 25% to 65%.

Os parâmetros de exposição adequados à população do município, bem como dados de toxicidade dos compostos selecionados, foram definidos a partir de fontes bibliográficas e bancos toxicológicos disponíveis. As tabelas de referência geradas são, em geral, mais restritivas para o Embasamento Cristalino em relação aos Depósitos Sedimentares. Comparados às tabelas de referência da Cetesb, os valores correspondentes a Porto Alegre são inferiores, resultando na necessidade de investigações ambientais mais detalhadas em áreas impactadas por hidrocarbonetos.This study defined RBSL (Risk Based Screening Levels values to hydrocarbons in Porto Alegre, Southern Brazil. The values were obtained through the RBCA methodology, using hydrogeological data from the Crystalline Altered Basement and the Quaternary Sedimentary Deposits. The exposure parameters appropriate to the urban population, as well as toxicity data of selected compounds, were obtained from bibliographical sources and toxicological databases. The reference tables demonstrated that the Crystalline Altered Basement values, in general, are more restrictive than those from the Quaternary Sedimentary Deposits. In comparison to Cetesb's reference tables, the values in Porto Alegre are lower, resulting in the need of more detailed environmental investigations in hydrocarbons polluted areas.

    A new Monte Carlo method termed Comb-like frame Monte Carlo is developed to simulate the soot dynamics. Detailed stochastic error analysis is provided. Comb-like frame Monte Carlo is coupled with the gas phase solver Chemkin II to simulate soot formation in a 1-D premixed burner stabilized flame. The simulated soot number density, volume fraction, and particle size distribution all agree well with the measurement available in literature. The origin of the bimodal distribution of particle size distribution is revealed with quantitative proof.

    An expression to calculate point values (the expected detector response of a particle emerging from a collision or the source) is derived and implemented in the MORSE-SGC/S Monte Carlo code. It is outlined how these point values can be smoothed as a function of energy and as a function of the optical thickness between the detector and the source. The smoothed point values are subsequently used to calculate the biasing parameters of the Monte Carlo runs to follow. The method is illustrated by an example, which shows that the obtained biasing parameters lead to a more efficient Monte Carlo calculation. (orig.)

    Full Text Available A leucemia mielomonocítica juvenil (LMMJ é uma doença rara, que representa de 2%a 3% de todas as leucemias pediátricas. É uma doença clonal de células da linhagem mieloide, que apresenta características de mieloproliferação e de displasia. Os sinais e os sintomas são resultantes da infiltração de células monocíticas malignas em órgãos não hematopoéticos. Os sintomas mais comuns são febre, tosse, infecção, fraqueza, palidez, linfadenopatia, hepatoesplenomegalia, lesões cutâneas e manifestações hemorrágicas. Como a LMMJ exibe um curso clínico muito agressivo e responde pobremente à quimioterapia, o transplante de células-tronco hematopoéticas é a única modalidade terapêutica curativa. Neste estudo, relatamos o caso de um paciente do sexo masculino, com um ano e dez meses de idade, que compareceu na emergência do Hospital de Clínicas de Porto Alegre por apresentar febre, com diagnóstico prévio de mononucleose feito em outra Instituição. A apresentação clínica, em conjunto com os achados laboratoriais, permitiu o diagnóstico correto. O paciente foi tratado com quimioterapia e submetido a transplante de células-tronco hematopoéticas.Juvenile myelomonocytic leukemia (JMML is a rare hematopoietic malignancy, which accounts for 2 to 3% of all pediatric leukemia.

    A substantial interpretation of electromagnetic induction (EMI) measurements requires quantifying optimal model parameters and uncertainty of a nonlinear inverse problem. For this purpose, an adaptive Bayesian Markov chain Monte Carlo (MCMC) algorithm is used to assess multi-orientation and multi-offset EMI measurements in an agriculture field with non-saline and saline soil. In the MCMC simulations, posterior distribution was computed using Bayes rule. The electromagnetic forward model based on the full solution of Maxwell\\'s equations was used to simulate the apparent electrical conductivity measured with the configurations of EMI instrument, the CMD mini-Explorer. The model parameters and uncertainty for the three-layered earth model are investigated by using synthetic data. Our results show that in the scenario of non-saline soil, the parameters of layer thickness are not well estimated as compared to layers electrical conductivity because layer thicknesses in the model exhibits a low sensitivity to the EMI measurements, and is hence difficult to resolve. Application of the proposed MCMC based inversion to the field measurements in a drip irrigation system demonstrate that the parameters of the model can be well estimated for the saline soil as compared to the non-saline soil, and provide useful insight about parameter uncertainty for the assessment of the model outputs.

    High-performance parallelism that is currently available is synchronous in nature. It is manifested in such architectures as Burroughs ILLIAC-IV, CDC STAR-100, TI ASC, CRI CRAY-1, ICL DAP, and many special-purpose array processors designed for signal processing. This form of parallelism has apparently not been of significant value to many important Monte Carlo calculations. Nevertheless, there is much asynchronous parallelism in many of these calculations. A model of a production code that requires up to 20 hours per problem on a CDC 7600 is studied for suitability on some asynchronous architectures that are on the drawing board. The code is described and some of its properties and resource requirements ae identified to compare with corresponding properties and resource requirements are identified to compare with corresponding properties and resource requirements are identified to compare with corresponding properties and resources of some asynchronous multiprocessor architectures. Arguments are made for programer aids and special syntax to identify and support important asynchronous parallelism. 2 figures, 5 tables

    Plasma behaviours are very complicated and the analyses are generally difficult. However, when the collisional processes play an important role in the plasma behaviour, the Monte Carlo method is often employed as a useful tool. For examples, in neutral particle injection heating (NBI heating), electron or ion cyclotron heating, and alpha heating, Coulomb collisions slow down high energetic particles and pitch angle scatter them. These processes are often studied by the Monte Carlo technique and good agreements can be obtained with the experimental results. Recently, Monte Carlo Method has been developed to study fast particle transports associated with heating and generating the radial electric field. Further it is applied to investigating the neoclassical transport in the plasma with steep gradients of density and temperatures which is beyong the conventional neoclassical theory. In this report, we briefly summarize the researches done by the present authors utilizing the Monte Carlo method. (author)

Essa tendência, predominante ao longo dos últimos anos, tem exigido dos espaços de atendimento escolar uma intensa ressignificação, favorecendo a ampliação do espectro de alunos atendidos pelo ensino comum e redefinindo a própria ação docente. São apresentadas as mudanças introduzidas na rede de ensino em questão em termos de uma reorganização curricular que tem como eixos: a flexibilidade, a participação coletiva, o trabalho coletivo de planejamento e avaliação, a necessidade de valorização de espaços de assessoria como espaços de formação. As salas de integração e recursos, como são designadas na rede investigada, são 14 para o atendimento de alunos com necessidades educativas especiais, envolvendo 28 educadores especiais e atendendo um conjunto de aproximadamente 600 alunos. Além do atendimento direto ao aluno, discute-se a função de assessoria e responsabilidade quanto à formação dos docentes em geral atribuída aos professores dessas salas. O principal aspecto analisado nessa relação serviço/formação diz respeito à necessária compreensão de diretrizes dos serviços que estejam em sintonia com as diretrizes gerais do projeto político-pedagógico da rede, assim como o reconhecimento de que a viabilidade e o efeito dessa proposta de formação tenham como bases: a pluralidade de vivência, as articulações entre os diferentes saberes e a capacidade reflexiva que contempla a prática docente.Abstract The objective of this paper is to analyze services

METHODS: A cross-sectional study was conducted involving a sample of 400 elderly subjects. Through a conglomerate analysis using the combined results of the Flanagan Scale and the quality of life assessment instrument developed by the World Health Organization (WHOQOL-100, the subjects classified as presenting a higher quality of life were considered to have aged successfully. RESULTS: After having been adjusted for the variables gender, age, level of depression, despair, perceived health status, meaning that personal beliefs give to life, satisfaction with social activities and relations, the following factors maintained their independent and meaningful effect on successful aging: family relations and friendships (OR = 4.93; 95% CI: 2.83-8.60, health and perceived well being (OR = 1.66; 95% CI: 1.07-2.59, functional capacity (OR = 23.70; 95% CI: 10.98-51.06 and psychosocial support (OR = 7.36; 95% CI: 4.00-13.54. CONCLUSIONS: Independence in performing daily life activities and autonomy, as well as satisfaction with family relations and friendships, were independent predictive factors of successful aging for both men and women. For women in particular, there were various predictive factors: material comfort; feeling physically well; body image and appearance; self-esteem; positive feelings; interpersonal relationships; social support; participation in recreational activities; sexuality; spirituality; and beliefs. The elderly maintain a relationship with themselves, with others and with their beliefs.

    Full Text Available OBJETIVO: descrever e analisar os resultados da sorologia convencional para toxoplasmose em gestantes acompanhadas pelo pré-natal do Hospital Materno-Infantil Presidente Vargas em Porto Alegre. MÉTODOS: IgG e IgM específicas foram processadas por testes fluorométricos, sendo a IgM de captura. Nova coleta em duas a três semanas foi solicitada às gestantes IgM positivas e as que estavam no início da gestação tiveram realizada a avidez de IgG. IgM neonatal foi obtida nos partos realizados na instituição. A análise foi baseada na distribuição binomial, por meio do cálculo de uma proporção simples para estimar a prevalência de soropositividade e suscetibilidade à infecção pelo Toxoplasma gondii. RESULTADOS: a prevalência da infecção em 10.468 gestantes foi de 61,1 e 38,7% das gestantes eram suscetíveis. Entre as 272 gestantes IgG e IgM positivas, 87 retornaram para nova coleta e em 84 os níveis de anticorpos permaneceram inalterados. De nove gestantes com avidez, houve apenas uma gestante com avidez baixa e a IgM neonatal do recém-nascido foi positiva. Em 44 recém-nascidos na instituição, a IgM neonatal foi positiva em quatro.

  18. Bayesian statistics and Monte Carlo methods

    Science.gov (United States)

    Koch, K. R.

    2018-03-01

    The Bayesian approach allows an intuitive way to derive the methods of statistics. Probability is defined as a measure of the plausibility of statements or propositions. Three rules are sufficient to obtain the laws of probability. If the statements refer to the numerical values of variables, the so-called random variables, univariate and multivariate distributions follow. They lead to the point estimation by which unknown quantities, i.e. unknown parameters, are computed from measurements. The unknown parameters are random variables, they are fixed quantities in traditional statistics which is not founded on Bayes' theorem. Bayesian statistics therefore recommends itself for Monte Carlo methods, which generate random variates from given distributions. Monte Carlo methods, of course, can also be applied in traditional statistics. The unknown parameters, are introduced as functions of the measurements, and the Monte Carlo methods give the covariance matrix and the expectation of these functions. A confidence region is derived where the unknown parameters are situated with a given probability. Following a method of traditional statistics, hypotheses are tested by determining whether a value for an unknown parameter lies inside or outside the confidence region. The error propagation of a random vector by the Monte Carlo methods is presented as an application. If the random vector results from a nonlinearly transformed vector, its covariance matrix and its expectation follow from the Monte Carlo estimate. This saves a considerable amount of derivatives to be computed, and errors of the linearization are avoided. The Monte Carlo method is therefore efficient. If the functions of the measurements are given by a sum of two or more random vectors with different multivariate distributions, the resulting distribution is generally not known. TheMonte Carlo methods are then needed to obtain the covariance matrix and the expectation of the sum.

  1. Successful vectorization - reactor physics Monte Carlo code

    International Nuclear Information System (INIS)

    Martin, W.R.

    1989-01-01

    Most particle transport Monte Carlo codes in use today are based on the ''history-based'' algorithm, wherein one particle history at a time is simulated. Unfortunately, the ''history-based'' approach (present in all Monte Carlo codes until recent years) is inherently scalar and cannot be vectorized. In particular, the history-based algorithm cannot take advantage of vector architectures, which characterize the largest and fastest computers at the current time, vector supercomputers such as the Cray X/MP or IBM 3090/600. However, substantial progress has been made in recent years in developing and implementing a vectorized Monte Carlo algorithm. This algorithm follows portions of many particle histories at the same time and forms the basis for all successful vectorized Monte Carlo codes that are in use today. This paper describes the basic vectorized algorithm along with descriptions of several variations that have been developed by different researchers for specific applications. These applications have been mainly in the areas of neutron transport in nuclear reactor and shielding analysis and photon transport in fusion plasmas. The relative merits of the various approach schemes will be discussed and the present status of known vectorization efforts will be summarized along with available timing results, including results from the successful vectorization of 3-D general geometry, continuous energy Monte Carlo.

  4. Monte Carlo simulation of Markov unreliability models

    Lewis, E.E.; Boehm, F.

    1984-01-01

    A Monte Carlo method is formulated for the evaluation of the unrealibility of complex systems with known component failure and repair rates. The formulation is in terms of a Markov process allowing dependences between components to be modeled and computational efficiencies to be achieved in the Monte Carlo simulation. Two variance reduction techniques, forced transition and failure biasing, are employed to increase computational efficiency of the random walk procedure. For an example problem these result in improved computational efficiency by more than three orders of magnitudes over analog Monte Carlo. The method is generalized to treat problems with distributed failure and repair rate data, and a batching technique is introduced and shown to result in substantial increases in computational efficiency for an example problem. A method for separating the variance due to the data uncertainty from that due to the finite number of random walks is presented. (orig.)

  5. Adiabatic optimization versus diffusion Monte Carlo methods

    2016-10-01

    Most experimental and theoretical studies of adiabatic optimization use stoquastic Hamiltonians, whose ground states are expressible using only real nonnegative amplitudes. This raises a question as to whether classical Monte Carlo methods can simulate stoquastic adiabatic algorithms with polynomial overhead. Here we analyze diffusion Monte Carlo algorithms. We argue that, based on differences between L1 and L2 normalized states, these algorithms suffer from certain obstructions preventing them from efficiently simulating stoquastic adiabatic evolution in generality. In practice however, we obtain good performance by introducing a method that we call Substochastic Monte Carlo. In fact, our simulations are good classical optimization algorithms in their own right, competitive with the best previously known heuristic solvers for MAX-k -SAT at k =2 ,3 ,4 .

    The formalism for the auxiliary-field Monte Carlo approach to the nuclear shell model is presented. The method is based on a linearization of the two-body part of the Hamiltonian in an imaginary-time propagator using the Hubbard-Stratonovich transformation. The foundation of the method, as applied to the nuclear many-body problem, is discussed. Topics presented in detail include: (1) the density-density formulation of the method, (2) computation of the overlaps, (3) the sign of the Monte Carlo weight function, (4) techniques for performing Monte Carlo sampling, and (5) the reconstruction of response functions from an imaginary-time auto-correlation function using MaxEnt techniques. Results obtained using schematic interactions, which have no sign problem, are presented to demonstrate the feasibility of the method, while an extrapolation method for realistic Hamiltonians is presented. In addition, applications at finite temperature are outlined

    We propose a Monte Carlo algorithm designed to simulate quantum as well as classical systems at equilibrium, bridging the algorithmic gap between quantum and classical thermal simulation algorithms. The method is based on a decomposition of the quantum partition function that can be viewed as a series expansion about its classical part. We argue that the algorithm not only provides a theoretical advancement in the field of quantum Monte Carlo simulations, but is optimally suited to tackle quantum many-body systems that exhibit a range of behaviors from "fully quantum" to "fully classical," in contrast to many existing methods. We demonstrate the advantages, sometimes by orders of magnitude, of the technique by comparing it against existing state-of-the-art schemes such as path integral quantum Monte Carlo and stochastic series expansion. We also illustrate how our method allows for the unification of quantum and classical thermal parallel tempering techniques into a single algorithm and discuss its practical significance.

  10. Random Numbers and Monte Carlo Methods

    Scherer, Philipp O. J.

    Many-body problems often involve the calculation of integrals of very high dimension which cannot be treated by standard methods. For the calculation of thermodynamic averages Monte Carlo methods are very useful which sample the integration volume at randomly chosen points. After summarizing some basic statistics, we discuss algorithms for the generation of pseudo-random numbers with given probability distribution which are essential for all Monte Carlo methods. We show how the efficiency of Monte Carlo integration can be improved by sampling preferentially the important configurations. Finally the famous Metropolis algorithm is applied to classical many-particle systems. Computer experiments visualize the central limit theorem and apply the Metropolis method to the traveling salesman problem.

    The main purpose of the report is to explain the relation between the transport equation and the Monte Carlo game used for its solution. The introduction of artificial particles carrying a weight provides one with high flexibility in constructing many different games for the solution of the same equation. This flexibility opens a way to construct a Monte Carlo game for the solution of the adjoint transport equation. Emphasis is laid mostly on giving a clear understanding of what to do and not on the details of how to do a specific game

    In many applications the histories of a normal Monte Carlo game rarely reach the target region. An approximate knowledge of the importance (with respect to the target) may be used to guide the particles more frequently into the target region. A Monte Carlo method is presented in which each history contributes to update the importance field such that eventually most target histories are sampled. It is a self-learning method in the sense that the procedure itself: (a) learns which histories are important (reach the target) and increases their probability; (b) reduces the probabilities of unimportant histories; (c) concentrates gradually on the more important target histories.

    The effective multiplication factor (k eff ) is defined as the ratio between the number of neutrons in successive generations, which definition is adopted by most Monte Carlo codes (e.g. MCNP). Also, it can be thought of as the ratio of the generation rate of neutrons by the sum of the leakage rate and the absorption rate, which should exclude the effect of the neutron reaction such as (n, 2n) and (n, 3n). This article discusses the Monte Carlo method for k eff calculation based on the second definition. A new code has been developed and the results are presented. (author)

    The precision of Radiosurgery Treatment planning systems is limited by the approximations of their algorithms and by their dosimetrical input data. This fact is especially important in small fields. However, the Monte Carlo methods is an accurate alternative as it considers every aspect of particle transport.

Relative shifts have been measured and furthermore, Dose-Volume Histograms have been calculated for target and adjacent organs at risk. (orig.)

    Monte Carlo methods are a class of computational algorithms that rely on repeated random sampling of physical and mathematical systems to compute their results. However, basic concepts of MC are both simple and straightforward and can be learned by using a personal computer. Uses of Monte Carlo methods require large amounts of random numbers, and it was their use that spurred the development of pseudorandom number generators, which were far quicker to use than the tables of random numbers which had been previously used for statistical sampling. In Monte Carlo simulation of radiation transport, the history (track) of a particle is viewed as a random sequence of free flights that end with an interaction event where the particle changes its direction of movement, loses energy and, occasionally, produces secondary particles. The Monte Carlo simulation of a given experimental arrangement (e.g., an electron beam, coming from an accelerator and impinging on a water phantom) consists of the numerical generation of random histories. To simulate these histories we need an interaction model, i.e., a set of differential cross sections (DCS) for the relevant interaction mechanisms. The DCSs determine the probability distribution functions (pdf) of the random variables that characterize a track; 1) free path between successive interaction events, 2) type of interaction taking place and 3) energy loss and angular deflection in a particular event (and initial state of emitted secondary particles, if any). Once these pdfs are known, random histories can be generated by using appropriate sampling methods. If the number of generated histories is large enough, quantitative information on the transport process may be obtained by simply averaging over the simulated histories. The Monte Carlo method yields the same information as the solution of the Boltzmann transport equation, with the same interaction model, but is easier to implement. In particular, the simulation of radiation

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex physical-socio-technical systems which we must understand to design a secure future for the nation. The Phoenix initiative implements CASoS Engineering principles combining the bottom up Complex Systems and Complex Adaptive Systems view with the top down Systems Engineering and System-of-Systems view. CASoS Engineering theory and practice must be conducted together to develop a discipline that is grounded in reality, extends our understanding of how CASoS behave and allows us to better control the outcomes. The pull of applications (real world problems) is critical to this effort, as is the articulation of a CASoS Engineering Framework that grounds an engineering approach in the theory of complex adaptive systems of systems. Successful application of the CASoS Engineering Framework requires modeling, simulation and analysis (MS and A) capabilities and the cultivation of a CASoS Engineering Community of Practice through knowledge sharing and facilitation. The CASoS Engineering Environment, itself a complex adaptive system of systems, constitutes the two platforms that provide these capabilities.

No obstante aún son pocas las iniciativas que tienden a interrumpir el flagelo, que deja grandes secuelas sociales y escandaliza a la opinión pública. Probablemente por el tabú que históricamente ha significado el sexo, suele ser problemática toda relación en la que esté implicado. Este artículo describe un estudio de caso realizado en el centro turístico de Buzios, en Brasil, donde se aplicaron tres variables en las cuales se encuentra involucrada la mujer, el turismo aparece como revelador del sexismo existente en la sociedad y queda manifiesta la eficacia de una política social de concientización en dos de las variables.

    Full Text Available Introdução: O raquitismo é uma doença do tecido ósseo em formação, onde há falha na calcificação e conseguinte acúmulo de tecido osteóide. O raquitismo carencial é decorrente da deficiência dos precursores da vitamina D, sendo a causa de raquitismo mais facilmente evitável e tratável. Objetivo: Relatar um caso, revisar a etiopatogenia e o tratamento do raquitismo carencial. Relato de caso: Paciente masculino com 2 anos de idade, previamente hígido, consulta com dificuldade de deambular progressiva, até incapacidade total da marcha. A criança tinha exposição aos raios solares regularmente, recebeu aleitamento materno até os 8 meses, mas não fez uso de vitamina D profilática. Ao exame havia deformidade óssea evidente em membros superiores e inferiores, principalmente com alargamento das metáfises distais e encurvamento das epífises dos ossos longos. A investigação laboratorial e de imagem confirmaram raquitismo carencial. Discussão: Há uma grande variedade nas possíveis etiologias do raquitismo, sendo doenças renais, hepáticas, distúrbios primários ou deficiências no metabolismo do cálcio e fósforo algumas delas. A maioria dessas patologias exige um longo período de investigação e tratamento. O raquitismo carencial, entretanto, é uma condição de relativa facilidade para diagnóstico, manejo, e profilaxia, derivando daí, a importância do artigo.

    Full Text Available Drosophila paulistorum Dobzhansky & Pavan, 1949 had initially been considered absent in anthropogenically disturbed environments, but in 1985 the detection of the species in Porto Alegre city, southern Brazil, suggested its potential to colonize new habitats and laid the foundations for ecologic studies on this species' populations. This study followed the variations in D. paulistorum populations in this town almost 20 years after its first local record. Drosophilid specimens were collected in sites with different urbanization grades and the results point to the expressive decline in D. paulistorum populations in Porto Alegre. This decline may be linked to urban growth and to naturally driven population decline, as imputed to climatic changes like variations in maximum and minimum temperatures as a consequence of a global climate warming. Also, the recent introduction of exotic species Zaprionus indianus Gupta, 1970 seems to play a role in this scenario, changing the interactions between native species.Drosophila paulistorum Dobzhansky & Pavan, 1949 era considerada inicialmente ausente em ambientes com influência antrópica, mas a detecção dessa espécie na cidade de Porto Alegre, sul do Brasil, em 1985, sugeriu seu potencial de colonização de novos ambientes e levou a fundação de estudos ecológicos com populações desta espécie. Este estudo acompanhou as variações populacionais de D. paulistorum nesta cidade quase 20 anos depois de seu primeiro registro neste local. Coletas de Drosophilidae foram realizadas em pontos com diferentes graus de urbanização e os resultados apontaram para uma expressiva diminuição dos tamanhos populacionais de D. paulistorum em Porto Alegre. Este declínio pode estar relacionado com o crescimento da cidade, assim como com retrações naturais no tamanho das populações devido a mudanças climáticas, tais como, variações nas temperaturas mínimas e máximas como conseqüência do aquecimento global

    2015-07-01

    The Monte Carlo method has become a fundamental tool for brachytherapy dosimetry mainly because no difficulties associated with experimental dosimetry. In brachytherapy the main handicap of experimental dosimetry is the high dose gradient near the present sources making small uncertainties in the positioning of the detectors lead to large uncertainties in the dose. This presentation will review mainly the procedure for calculating dose distributions around a fountain using the Monte Carlo method showing the difficulties inherent in these calculations. In addition we will briefly review other applications of the method of Monte Carlo in brachytherapy dosimetry, as its use in advanced calculation algorithms, calculating barriers or obtaining dose applicators around.

    2002-01-01

    The possibilities of Monte Carlo modeling for dose calculations and optimization treatment are quite limited in radiation oncology applications. The main reason is that the Monte Carlo technique for dose calculations is time consuming while treatment planning may require hundreds of possible cases of dose simulations to be evaluated for dose optimization. The second reason is that general-purpose codes widely used in practice, require an experienced user to customize them for calculations. This paper discusses the concept of Monte Carlo code design that can avoid the main problems that are preventing wide spread use of this simulation technique in medical physics. (authors)

    2009-03-01

    The stochastic approximation Monte Carlo (SAMC) algorithm has recently been proposed as a dynamic optimization algorithm in the literature. In this paper, we show in theory that the samples generated by SAMC can be used for Monte Carlo integration via a dynamically weighted estimator by calling some results from the literature of nonhomogeneous Markov chains. Our numerical results indicate that SAMC can yield significant savings over conventional Monte Carlo algorithms, such as the Metropolis-Hastings algorithm, for the problems for which the energy landscape is rugged. © 2008 Elsevier B.V.

    This qualitative study aims to describe the trajectories of female victims of gender violence in Porto Alegre, Rio Grande do Sul State, Brazil. The methodology included in-depth interviews with women and staff, attempting to map the critical paths of women when they made the decision to seek professional help. We interviewed 21 women victims of gender violence and 25 professionals, including law enforcement officials, health and social workers, and nongovernmental organizations. The women's trajectories in the services were mapped, identifying facilitating factors and obstacles in the process of breaking with gender violence. The victims reported: pressure by professional staff to return to their marriages and police inefficiency in providing protection. The discourse of law enforcement officials and health and social workers showed a range of different concepts regarding violence, medicalization of violence, and network fragmentation.

    Full Text Available The article discusses the representation of the city in cultural journalism, examining how the cultural section of the newspaper Diário do Sul (which belonged to Gazeta Mercantil’s group offered a perspective of Porto Alegre from 1986 to 1988. The study summarizes a large part of the research results conducted by means of content analysis and thematic oral history techniques. It was perceived that the coverage, anchored in positivity, builds up the city as a place of consumption, of novelty, of updating and of the continuous movement of external flows. It reveals the geographic centralization of the circuit, investments in culture institutionalization and in the renewal of the city`s infrastructure. In the tension between the references that create belonging and those that expand the territory, journalism represents the city as the center of the show, inserted in a phenomenon of the recent decades, when cities became decisive agents in the realm of culture.

Methods: Interventional, longitudinal and describing quantitative work, accomplished with 41 preschool children from four to six years old, living in the area assisted by a Family Health Team (Equipe de Saúde da Família-ESF in the city of Porto Alegre-RS. Diagnosis of dental caries and gingivitis was carried out through oral clinical examination at the beginning and at the end of the study. The dietary pattern was obtained by applying a questionnaire and the social-sanitary aspects of the families, from the records of File A in the Basic Health Care Information System (Sistema de Informação da Atenção Básica-SIAB. Results: Caries disease was diagnosed in 58.5% of the children, whose dmft index (total sum of decayed, extracted and filled teeth was 2.43. There was a decrease in the number of decayed teeth and an increase in extracted and filled teeth. The rates of visible plaque and gums bleeding got better. The social-sanitary aspects were standardized in the community, being not representative. The group presenting the highest dmft values followed a diet containing sugars, with viscous consistence and an intake frequency of four or more times a day. Conclusion: The activities of health promotion developed in the school partially changed the children’s oral conditions. There was a positive correlation between consistency, composition and frequency of diet and the presence of caries disease; on the other hand, there was no significant relation between social-sanitary conditions and the presence of oral diseases

    Today there is an insufficient number of donated organs in Brazil. This is particularly due to the general population's and health care professionals' lack of information. Therefore, with this project we intend to consolidate knowledge on organ donation to teach health care students of different areas so they are able to propagate such knowledge. In 2006, at Universidade Federal de Ciências da Saúde de Porto Alegre, an "Organ donation and transplants" subject was created, with the aim to educate health care students. In the next years, it was split in two subjects, named "Introduction to transplants" and "Donation and transplants." By enrolling, students get theoretical classes and practical experience in out- and inpatient facilities and in surgical environments at the Santa Casa Hospital Complex. Furthermore, they can participate in campaigns at parks, stadiums, and health care fairs that take place at several schools in Porto Alegre. To finish the subjects, students present a conclusion report. Seven years after implementation of the subject, and with more than 400 students enrolled, several accomplishments can be highlighted. For example, the creation of the Organ Transplantation League, the implementation of a day to spread conception of the donation-transplant process (with the elaboration of a Web page on the subject), and the release of a book on the subject written by students and professors. Health care professionals' education is a central point in donation and transplant process. This is because they become, inevitably, educators, and this brings a long-term consequence, consisting of enhanced logistics skills on brain-death diagnosis and further transfer of information to the population (hopefully reducing denial by families at the time of the donation). We conclude that this is a project to be followed by other medical schools so that, effectively, the number of donors increases and, consequently, the transplantation of organs and tissues as well

    The Monte Carlo method has been used for many years to analyze the neutronics of nuclear reactors. In fact, as the power of computers has increased the importance of Monte Carlo in neutronics has also increased, until today this method plays a central role in reactor analysis and design. Monte Carlo is used in neutronics for two somewhat different purposes, i.e., (a) to compute the distribution of neutrons in a given medium when the neutron source-density is specified, and (b) to compute the neutron distribution in a self-sustaining chain reaction, in which case the source is determined as the eigenvector of a certain linear operator. In (b), then, the source is not given, but must be computed. In the first case (the ``fixed-source`` case) the Monte Carlo calculation is unbiased. That is to say that, if the calculation is repeated (``replicated``) over and over, with independent random number sequences for each replica, then averages over all replicas will approach the correct neutron distribution as the number of replicas goes to infinity. Unfortunately, the computation is not unbiased in the second case, which we discuss here.

    1986-01-01

    A new computer system for Monte Carlo Experimentation is presented. The new system speeds and simplifies the process of coding and preparing a Monte Carlo Experiment; it also encourages the proper design of Monte Carlo Experiments, and the careful analysis of the experimental results. A new functional language is the core of this system. Monte Carlo Experiments, and their experimental designs, are programmed in this new language; those programs are compiled into Fortran output. The Fortran output is then compiled and executed. The experimental results are analyzed with a standard statistics package such as Si, Isp, or Minitab or with a user-supplied program. Both the experimental results and the experimental design may be directly loaded into the workspace of those packages. The new functional language frees programmers from many of the details of programming an experiment. Experimental designs such as factorial, fractional factorial, or latin square are easily described by the control structures and expressions of the language. Specific mathematical modes are generated by the routines of the language

This combines features of deterministic molecular dynamics techniques and conventional Monte Carlo simulations. For discrete systems the method can be programmed to run an order of magnitude faster than other approaches. It does not require high quality random numbers and may also be useful for nonequilibrium studies. 10 references

    This series of slides is divided into 3 parts. The first part is dedicated to the presentation of the Monte-Carlo computational performance benchmark (aims, specifications and results). This benchmark aims at performing a full-size Monte Carlo simulation of a PWR core with axial and pin-power distribution. Many different Monte Carlo codes have been used and their results have been compared in terms of computed values and processing speeds. It appears that local power values mostly agree quite well. The first part also includes the presentations of about 10 participants in which they detail their calculations. In the second part, an extension of the benchmark is proposed in order to simulate a more realistic reactor core (for instance non-uniform temperature) and to assess feedback coefficients due to change of some parameters. The third part deals with another benchmark, the BEAVRS benchmark (Benchmark for Evaluation And Validation of Reactor Simulations). BEAVRS is also a full-core PWR benchmark for Monte Carlo simulations

    Detailed Monte Carlo calculations of uranium calorimetry are presented which reveal a significant difference in the responses of liquid argon and plastic scintillator in uranium calorimeters. Due to saturation effects, neutrons from the uranium are found to contribute only weakly to the liquid argon signal. Electromagnetic sampling inefficiencies are significant and contribute substantially to compensation in both systems. 17 references

    Coded apertures using Uniformly Redundant Arrays (URA) have been unsuccessfully evaluated for two-dimensional and three-dimensional imaging in Nuclear Medicine. The images reconstructed from coded projections contain artifacts and suffer from poor spatial resolution in the longitudinal direction. We introduce a Maximum-Likelihood Expectation-Maximization (MLEM) algorithm for three-dimensional coded aperture imaging which uses a projection matrix calculated by Monte Carlo simulations. The aim of the algorithm is to reduce artifacts and improve the three-dimensional spatial resolution in the reconstructed images. Firstly, we present the validation of GATE (Geant4 Application for Emission Tomography) for Monte Carlo simulations of a coded mask installed on a clinical gamma camera. The coded mask modelling was validated by comparison between experimental and simulated data in terms of energy spectra, sensitivity and spatial resolution. In the second part of the study, we use the validated model to calculate the projection matrix with Monte Carlo simulations. A three-dimensional thyroid phantom study was performed to compare the performance of the three-dimensional MLEM reconstruction with conventional correlation method. The results indicate that the artifacts are reduced and three-dimensional spatial resolution is improved with the Monte Carlo-based MLEM reconstruction.

  17. The scientific observatories on Mont Blanc.

    Since the first ascent of Mont Blanc by Jacques Balmat and Dr. Michel-Gabriel Paccard in 1786, numerous scientific events have taken place on the highest peak of Europe. Horace Benédict de Saussure, since his first ascent in 1787, made numerous observations on barometric pressure, temperature, geology, and mountain sickness on Mont Blanc. Over the next 100 years, scientists and physicians climbed Mont Blanc and made many interesting although anecdotal reports. Science on Mont Blanc exploded at the end of the 19th century. A major player at that time was Joseph Vallot (1854-1925), who constructed an observatory in 1890 at 4,358 m on the Rochers des Bosses and then moved it in 1898 to a better location at 4,350 m. There Vallot and invited scientists made observations over more than 30 years: studies in geology, glaciology, astronomy, cartography, meteorology, botany, physiology and medicine were performed and published in the seven volumes of the Annales de l'Observatoire du Mont Blanc, between 1893 and 1917, and in the Comptes Rendus de l'Académie des Sciences. While Jules Janssen and Xaver Imfeld were preparing the construction of the new observatory on the top of Mont Blanc, Dr. Jacottet died in 1891 at the Observatoire Vallot from a disease that was clearly attributed by Dr. Egli-Sinclair to the effect of high altitude. This was probably the first case of high altitude pulmonary edema documented by an autopsy and suspected to be directly due to high altitude. Extensive studies on ventilation were made from 1886 to 1900. Increase in ventilation with altitude was documented, with the phenomenon of "ventilatory acclimatization." Paul Bert's theories on the role of oxygen in acute mountain sickness were confirmed in 1903 and 1904 by studying the effects of oxygen inhalation. In 1913, Vallot documented for the first time the decrease in physical performance at the top of Mont Blanc using squirrels. After that pioneering era, few studies were done until 1984, when a

  18. Uncertainty analysis in Monte Carlo criticality computations

    Highlights: ► Two types of uncertainty methods for k eff Monte Carlo computations are examined. ► Sampling method has the least restrictions on perturbation but computing resources. ► Analytical method is limited to small perturbation on material properties. ► Practicality relies on efficiency, multiparameter applicability and data availability. - Abstract: Uncertainty analysis is imperative for nuclear criticality risk assessments when using Monte Carlo neutron transport methods to predict the effective neutron multiplication factor (k eff ) for fissionable material systems. For the validation of Monte Carlo codes for criticality computations against benchmark experiments, code accuracy and precision are measured by both the computational bias and uncertainty in the bias. The uncertainty in the bias accounts for known or quantified experimental, computational and model uncertainties. For the application of Monte Carlo codes for criticality analysis of fissionable material systems, an administrative margin of subcriticality must be imposed to provide additional assurance of subcriticality for any unknown or unquantified uncertainties. Because of a substantial impact of the administrative margin of subcriticality on economics and safety of nuclear fuel cycle operations, recently increasing interests in reducing the administrative margin of subcriticality make the uncertainty analysis in criticality safety computations more risk-significant. This paper provides an overview of two most popular k eff uncertainty analysis methods for Monte Carlo criticality computations: (1) sampling-based methods, and (2) analytical methods. Examples are given to demonstrate their usage in the k eff uncertainty analysis due to uncertainties in both neutronic and non-neutronic parameters of fissionable material systems.

A pesar de estos avances, la mortalidad hospitalaria sigue siendo muy elevada. Nuestro objetivo fue analizar las características de los pacientes con endocarditis infecciosa activa y su relación con la mortalidad hospitalaria a lo largo de 16 años. Se realizó un registro prospectivo entre 1994 y 2010 de pacientes ingresados con endocarditis. Se analizaron características clínicas, evolución y tratamiento y se registraron los eventos intrahospitalarios. Ingresaron 152 pacientes, 64.5% varones, edad 45 ± 16 años, las causas más frecuentes de cardiopatía de base fueron: congénita 32 (21% y reumática 20 (13.2%. Los motivos de internación fueron síndrome febril 116 (76.3% e insuficiencia cardíaca 61 (40.1%. Se identificó el agente infeccioso en 106 (69.7% de los casos, el más frecuente fue Streptococcus viridans. El ecocardiograma mostró vegetaciones en 123 (80.9% de los pacientes y 88 (57.8% presentaron complicaciones durante su internación, siendo la más frecuente la insuficiencia cardíaca.

    Gentile, N.; Procassini, R.; Scott, H.

    Monte Carlo methods are frequently used for neutron and radiation transport. These methods have several advantages, such as relative ease of programming and dealing with complex meshes. Disadvantages include long run times and statistical noise. Monte Carlo photon transport calculations also often suffer from inaccuracies in matter temperature due to the lack of implicitness. In this paper we discuss the Monte Carlo algorithm as it is applied to neutron and photon transport, detail the differences between neutron and photon Monte Carlo, and give an overview of the ways the numerical method has been modified to deal with issues that arise in photon Monte Carlo simulations

  7. Multilevel sequential Monte-Carlo samplers

    KAUST Repository

    2016-01-05

    Multilevel Monte-Carlo methods provide a powerful computational technique for reducing the computational cost of estimating expectations for a given computational effort. They are particularly relevant for computational problems when approximate distributions are determined via a resolution parameter h, with h=0 giving the theoretical exact distribution (e.g. SDEs or inverse problems with PDEs). The method provides a benefit by coupling samples from successive resolutions, and estimating differences of successive expectations. We develop a methodology that brings Sequential Monte-Carlo (SMC) algorithms within the framework of the Multilevel idea, as SMC provides a natural set-up for coupling samples over different resolutions. We prove that the new algorithm indeed preserves the benefits of the multilevel principle, even if samples at all resolutions are now correlated.

    At Los Alamos the early work of Fermi, von Neumann, and Ulam has been developed and supplemented by many followers, notably Cashwell and Everett, and the main product today is the continuous-energy, general-purpose, generalized-geometry, time-dependent, coupled neutron-photon transport code called MCNP. The Los Alamos Monte Carlo research and development effort is concentrated in Group X-6. MCNP treats an arbitrary three-dimensional configuration of arbitrary materials in geometric cells bounded by first- and second-degree surfaces and some fourth-degree surfaces (elliptical tori). Monte Carlo has evolved into perhaps the main method for radiation transport calculations at Los Alamos. MCNP is used in every technical division at the Laboratory by over 130 users about 600 times a month accounting for nearly 200 hours of CDC-7600 time

    Theoretical study of selected gamma-ray and electron diagnostic necessitates coupling Cerenkov radiation to electron/photon cascades. A Cerenkov production model and its incorporation into a general geometry Monte Carlo coupled electron/photon transport code is discussed. A special optical photon ray-trace is implemented using bulk optical properties assigned to each Monte Carlo zone. Good agreement exists between experimental and calculated Cerenkov data in the case of a carbon-dioxide gas Cerenkov detector experiment. Cerenkov production and threshold data are presented for a typical carbon-dioxide gas detector that converts a 16.7 MeV photon source to Cerenkov light, which is collected by optics and detected by a photomultiplier

    Since its publication, the reptation quantum Monte Carlo algorithm of Baroni and Moroni (1999 Phys. Rev. Lett. 82 4745) has been applied to several important problems in physics, but its mathematical foundations are not well understood. We show that their algorithm is not of typical Metropolis-Hastings type, and we specify conditions required for the generated Markov chain to be stationary and to converge to the intended distribution. The time-step bias may add up, and in many applications it is only the middle of a reptile that is the most important. Therefore, we propose an alternative, 'no-compromise reptation quantum Monte Carlo' to stabilize the middle of the reptile. (fast track communication)

    2015-10-01

    In this article, we study the application of multilevel Monte Carlo (MLMC) approaches to numerical random homogenization. Our objective is to compute the expectation of some functionals of the homogenized coefficients, or of the homogenized solutions. This is accomplished within MLMC by considering different sizes of representative volumes (RVEs). Many inexpensive computations with the smallest RVE size are combined with fewer expensive computations performed on larger RVEs. Likewise, when it comes to homogenized solutions, different levels of coarse-grid meshes are used to solve the homogenized equation. We show that, by carefully selecting the number of realizations at each level, we can achieve a speed-up in the computations in comparison to a standard Monte Carlo method. Numerical results are presented for both one-dimensional and two-dimensional test-cases that illustrate the efficiency of the approach.

These papers are combined into one report for convenience and because they are related to each other. The first paper (by Thompson and Cashwell) is a general survey about X-6 and MCNP and is an introduction to the other three papers. It can also serve as a resume of X-6. The second paper (by Godfrey) explains some of the details of geometry specification in MCNP. The third paper (by Cashwell and Schrandt) illustrates calculating flux at a point with MCNP; in particular, the once-more-collided flux estimator is demonstrated. Finally, the fourth paper (by Thompson, Deutsch, and Booth) is a tutorial on some variance-reduction techniques. It should be required for a fledging Monte Carlo practitioner

    Simulations of QCD suffer from severe critical slowing down towards the continuum limit. This problem is known to be prominent in the topological charge, however, all observables are affected to various degree by these slow modes in the Monte Carlo evolution. We investigate the slowing down in high statistics simulations and propose a new error analysis method, which gives a realistic estimate of the contribution of the slow modes to the errors. (orig.)

  7. Generalized hybrid Monte Carlo - CMFD methods for fission source convergence

    International Nuclear Information System (INIS)

    Wolters, Emily R.; Larsen, Edward W.; Martin, William R.

    2011-01-01

    In this paper, we generalize the recently published 'CMFD-Accelerated Monte Carlo' method and present two new methods that reduce the statistical error in CMFD-Accelerated Monte Carlo. The CMFD-Accelerated Monte Carlo method uses Monte Carlo to estimate nonlinear functionals used in low-order CMFD equations for the eigenfunction and eigenvalue. The Monte Carlo fission source is then modified to match the resulting CMFD fission source in a 'feedback' procedure. The two proposed methods differ from CMFD-Accelerated Monte Carlo in the definition of the required nonlinear functionals, but they have identical CMFD equations. The proposed methods are compared with CMFD-Accelerated Monte Carlo on a high dominance ratio test problem. All hybrid methods converge the Monte Carlo fission source almost immediately, leading to a large reduction in the number of inactive cycles required. The proposed methods stabilize the fission source more efficiently than CMFD-Accelerated Monte Carlo, leading to a reduction in the number of active cycles required. Finally, as in CMFD-Accelerated Monte Carlo, the apparent variance of the eigenfunction is approximately equal to the real variance, so the real error is well-estimated from a single calculation. This is an advantage over standard Monte Carlo, in which the real error can be underestimated due to inter-cycle correlation. (author)

    It is well-known that the Monte Carlo method is very successful in tackling several kinds of system simulations. It often happens that one has to deal with rare events, and the use of a variance reduction technique is almost mandatory, in order to have Monte Carlo efficient applications. The main issue associated with variance reduction techniques is related to the choice of the value of the biasing parameter. Actually, this task is typically left to the experience of the Monte Carlo user, who has to make many attempts before achieving an advantageous biasing. A valuable result is provided: a methodology and a practical rule addressed to establish an a priori guidance for the choice of the optimal value of the biasing parameter. This result, which has been obtained for a single component system, has the notable property of being valid for any multicomponent system. In particular, in this paper, the exponential and the uniform biases of exponentially distributed phenomena are investigated thoroughly

    Full Text Available BACKGROUND: Phototherapy consists of exposure to ultraviolet radiation for therapeutic reasons. Radiation is already used in dermatological practice, and many studies have already proved the beneficial effect of UV light treatment for chronic inflammatory or lymphoproliferative skin diseases. The Dermatology Service of the Clinics Hospital of Porto Alegre (Hospital de Clínicas de Porto Alegre has been using phototherapy for a long time, and no official data have been described so far. OBJECTIVES: To study the prevalence of dermatoses referred to the phototherapy unit at the Clinics Hospital of Porto Alegre and describe the total number of patients who have already been referred to this sector and their phototype. METHODS: This is a descriptive cross-sectional study. Data were collected through a review of the phototherapy patients' records (secondary data, which are available on a database of the Dermatology Service of the Clinics Hospital of Porto Alegre, from August 1997 to July 2011. RESULTS: A total of 653 records were analyzed. Phototype 3 was the most prevalent (n=313. Distribution of the prevalence of dermatoses referred to the phototherapy unit was as follows: vitiligo (279, psoriasis (255, cutaneous T-cell lymphoma/mycosis fungoides (29, graftversus-host disease (15, scleroderma (11, atopic dermatitis (10, alopecia areata (6, parapsoriasis (5, eczema (4, granuloma annulare (4, and others (35. As vitiligo and psoriasis were the two most prevalent dermatoses, they were analyzed separately, with no statistical difference in prevalence between them (P=0,177. CONCLUSIONS: Our findings are in accordance with the literature, showing that although phototherapy is still mostly indicated to treat psoriasis, it has been used to treat other dermatoses, since the results are promising. FUNDAMENTOS: Fototerapia é exposição à radiação ultravioleta para uso terapêutico. O uso dessas radiações já é utilizado na prática dermatológica, e

    Full Text Available Este artigo dedica-se a refletir sobre maus-tratos e a vinculação entre a mãe e seu bebê, sendo importante destacar que uma das principais conseqüências da má formação desse vínculo são os maus-tratos. O artigo expõe uma discussão teórico/prática relacionada aos aspectos teóricos da experiência clínica de dois anos de estágio profissional de Psicologia na enfermaria de queimados, no Hospital de Pronto Socorro de Porto Alegre. Foram estudados, durante o período, cinqüenta casos. O presente artigo descreve um dos atendimentos. O critério utilizado para a escolha foi a de que o caso é típico e oferece possibilidade de aprendizagem para o leitor. A abordagem utilizada no atendimento da díade foi a psicoterapia breve, com enfoque psicanalítico. Com base no acompanhamento desse caso clínico, pode-se concluir que a forma como a mãe atendida consegue se relacionar com o filho evidencia que a mesma se encontra incapacitada para desempenhar uma função materna adequada ao desenvolvimento da criança. Um dos fatores que contribui para isso é a história pregressa da mãe, observada durante os atendimentos psicológicos: doença mental devido a maus-tratos no passado. É importante destacar que o atendimento psicoterápico funcionou, no estudo, como um dispositivo de saúde e resgate desse vínculo. Diante desse quadro, elaborou-se uma proposta que tem como objetivo promover a saúde e/ou prevenir a doença, tanto do bebê quanto da mãe, iniciando o mais breve possível, o diagnóstico e o acompanhamento psicológico (ou psiquiátrico, que deverá ter continuidade após a internação e durante o desenvolvimento da criança.

    Full Text Available Face à relevância da presença de árvores distribuídas em ruas e avenidas nos ambientes urbanos, o presente estudo buscou identificar as espécies arbóreas utilizadas ao longo de ruas com túneis verdes e avaliar as condições desta vegetação em Porto Alegre, RS. A relação entre porte da árvore versus condições do tronco foi investigada, buscando-se estimar uma possível relação de conflito entre exemplares de grande porte e redes de serviços aéreas. Para tanto, foram realizados levantamentos quali-quantitativos da vegetação em nove ruas da cidade (cinco túneis verdes e quatro vias controle. Foram efetuados 760 registros de 61 espécies vegetais, 25 nativas e 36 exóticas, agrupadas em 33 famílias botânicas perfazendo apenas cerca de 34 % das espécies arbóreas registradas em Porto Alegre. Estes dados alertam para a necessidade de implantação de arborização viária mais heterogênea e composta de plantas nativas. Os túneis verdes apresentaram menos espécies e indivíduos menos preservados que as vias controle, situação atribuída em parte à maior estatura da vegetação presente nos túneis. Como alternativa às situações que representam conflitos entre os exemplares de porte arbóreo e os serviços de infra-estrutura aéreos implantados nas vias, recomenda-se a adoção de rede compacta para distribuição de energia elétrica.

    Full Text Available Introdução: O Complexo de Esclerose Tuberosa (CET é uma síndrome neurocutânea transmitida hereditariamente, de traço autossômico dominante e que se manifesta por uma tríade clássica: deficiência mental, convulsões e adenoma sebáceo. A mutação responsável pela síndrome está presente em até 85% dos portadores de CET e.ocorre nos genes supressores tumorais TSC1 e TSC2, que produzem hamartina e tuberina, respectivamente.A prevalência do CET é de 1:10.000 a 1:170.000, atinge mais indivíduos do sexo masculina e é rara em negros. Relato de Caso: R.C.S.B., paciente do sexo feminino, 16 anos, vem encaminhada ao ambulatório de neurologia devido a quadro de convulsões tônico-clônicas generalizadas e crises de ausência diárias há 1 ano, mas com história de convulsões aos 2 anos que cessaram espontaneamente. Está em tratamento com fenitoína 200mg/dia e carbamazepina 800mg/dia, mas ainda apresenta crises de ausência. A paciente apresenta as lesões cutâneas típicas do CET: adenomas sebáceos (angiofibroma em face distribuídos simetricamente entre nariz e bochechas, envolvendo ainda fronte e queixo. Não há sinais de retardo mental. A ressonância nuclear magnética revelou imagens com padrão compatível com áreas de desmielinização. O eletroencefalograma encontrava-se normal. Conclusão: O tratamento do CET ainda é um desafio para muitos neurologistas, uma vez que não há tratamento específico para doença. A paciente deve contar com equipe multidisciplinar, por vezes é necessário acompanhamento com neurologista, dermatologista, geneticista, psicólogos e outros, dependendo das manifestações do CET. A finalidade terapêutica é a qualidade de vida da paciente, que pode ser prejudicada pelas várias convulsões ou alterações estéticas da doença.

As lesões estão sempre presentes ao nascimento, permanecem estáveis por toda a vida e caracterizam-se por rigorosa simetria.³ Máculas hiperpigmentadas normalmente são vistas dentro e ao redor das áreas de hipopigmentação. 4A doença ocorre devido a mutações do gene c-kit, localizado no cromossomo 4q12, ou do Slug gene, no cromossomo 8q11, as quais resultam numa diminuição da sinalização do receptor de tirosina-quinase, prejudicando o desenvolvimento dos melanoblastos e sua migração da crista neural e, consequentemente, a síntese de melanina.5 Relata-se o caso de paciente do sexo feminino, encaminhada ao ambulatório de genética do CHS aos 3 meses de idade, por apresentar, desde o nascimento, mecha branca no cabelo e pigmentação irregular da pele. Ao exame físico: base nasal alargada, mecha branca frontal, irregularidade de pigmentação com áreas hipopigmentadas simétricas em tronco e membros e mancha hipocrômica frontal de formato triangular. A despigmentação da pele do piebaldismo não responde a medicamentos e fototerapia. As áreas despigmentadas perdem parte da barreira de proteção da pele fornecida pelos melanócitos.6 Vários métodos cirúrgicos vem sendo desenvolvidos, incluindo transferência de melanócitos por enxerto de pele total ou parcial, por punch (minigrafting, bolhas de sucção ou cultura de melanócitos e queratinócitos.7 A repigmentação pode ser vista dentro de 6-8 meses, com a cor da pele se assemelhando à da pele normal circundante.8

    Designing and testing new equipment can be an expensive and time consuming process or the desired performance characteristics may preclude its construction due to technological shortcomings. Cost may also prevent equipment being purchased for other scenarios to be tested. An alternative is to use Monte Carlo simulations to make the investigations. This presentation exemplifies how Monte Carlo code calculations can be used to fill the gap. An example is given for the investigation of two sizes of germanium detector (70 mm and 80 mm diameter) at four different crystal thicknesses (15, 20, 25, and 30 mm) and makes predictions on how the size affects the counting efficiency and the Minimum Detectable Activity (MDA). The Monte Carlo simulations have shown that detector efficiencies can be adequately modelled using photon transport if the data is used to investigate trends. The investigation of the effect of detector thickness on the counting efficiency has shown that thickness for a fixed diameter detector of either 70 mm or 80 mm is unimportant up to 60 keV. At higher photon energies, the counting efficiency begins to decrease as the thickness decreases as expected. The simulations predict that the MDA of either the 70 mm or 80 mm diameter detectors does not differ by more than a factor of 1.15 at 17 keV or 1.2 at 60 keV when comparing detectors of equivalent thicknesses. The MDA is slightly increased at 17 keV, and rises by about 52% at 660 keV, when the thickness is decreased from 30 mm to 15 mm. One could conclude from this information that the extra cost associated with the larger area Ge detectors may not be justified for the slight improvement predicted in the MDA. (author)

    Full Text Available RESUMO: O granuloma leproide canino (GLC é uma doença micobacteriana que cursa com lesão nodular, cutânea ou subcutânea, tipicamente auto limitante, decorrente de infecção pelo Mycobacterium. É uma doença dermatológica rara, usualmente relatada em países de clima tropical. O objetivo deste trabalho é caracterizar as alterações microscópicas e epidemiológicas de casos de GLC. Além disso, utilizar exames complementares para demonstração do Mycobacterium sp. na lesão analisada utilizando coloração de Ziehl-Neelsen, imuno-histoquímica e PCR para classificação e sequenciamento da espécie de Mycobacterium. Foram analisados 27 casos de GLC diagnosticados no período compreendido de 2005 a 2014 (21 exames histológicos e seis citológicos. A raça mais acometida foi Boxer (33,3%, seguida da Dachshund (11,1%. Foi frequente o acometimento de caninos de grande porte (64% e de pelame curto (96%. Não foi possível estabelecer qualquer padrão de sazonalidade do GLC. As lesões se localizaram anatomicamente no pavilhão auricular na maioria dos casos (93%, constituindo-se de nódulos únicos ou múltiplos, ulcerados ou não. Em nenhum dos casos foi observado acometimento sistêmico. Lesões histológicas seguiram três padrões que variaram de nodulares a difusos, com infiltrado granulomatoso/piogranulomatoso com envolvimento de derme superficial e profunda. A observação de bacilos pela coloração de Ziehl-Neelsen confirmou o diagnóstico. Este teste demonstrou grande variação na quantidade de bacilos nas lesões, não relacionado estatisticamente ao tipo da lesão nem ao período evolutivo. A imuno-histoquímica foi positiva em 90% dos casos, e em alguns casos facilitou a identificação de bacilos, entretanto, em dois casos ocorreram resultados negativos mesmo havendo marcação pela coloração de Ziehl-Neelsen. Na técnica de PCR realizada em 18 amostras, 44% dos casos foram positivos, duas sequências inespecíficas, e

Se notifican entre quinientas y mil picaduras de medusas por temporada en la localidad balnearia de Monte Hermoso, al sur de la provincia de Buenos Aires. El daño cutáneo que provoca por su elevada acción urticante plantea un serio inconveniente para el desarrollo del turismo. Durante el mes de enero de 1998, en la localidad de Monte Hermoso se reunieron un total de 49 casos que fueron examinados dentro de la hora posterior a la picadura. Veintiocho eran de sexo masculino (57.1%. La edad promedio fue de 16 ± 4.1 (rango 5-80. El 54% presentó lesiones eritemato-edematosas de configuración lineal, el 28% presentó lesiones predominantemente eritematosas y el 18% presentó placas eritemato-edematosas. En el 73% de los casos las lesiones se localizaron en miembros inferiores. Hemos redefinido la lesión cutánea producida por la medusa O. sambaquiensis, su evolución, sus dimensiones y localizaciones más frecuentes. Además, se ha tipificado y cuantificado el dolor que produce, y otros signos y síntomas que acompañan a la picadura en la hora posterior, a las primeras 24 horas y a los 30 días. Describimos las conductas terapéuticas utilizadas en nuestra costa, evaluamos la efectividad de algunas de ellas en el control del dolor y finalmente proponemos un esquema terapéutico para dicha picadura.

  10. Monte Carlo eigenfunction strategies and uncertainties

    International Nuclear Information System (INIS)

    Gast, R.C.; Candelore, N.R.

    1974-01-01

    Comparisons of convergence rates for several possible eigenfunction source strategies led to the selection of the ''straight'' analog of the analytic power method as the source strategy for Monte Carlo eigenfunction calculations. To insure a fair game strategy, the number of histories per iteration increases with increasing iteration number. The estimate of eigenfunction uncertainty is obtained from a modification of a proposal by D. B. MacMillan and involves only estimates of the usual purely statistical component of uncertainty and a serial correlation coefficient of lag one. 14 references. (U.S.)

    Biological membranes are complex assemblies of many different molecules of which analysis demands a variety of experimental and computational approaches. In this article, we explain challenges and advantages of atomistic Monte Carlo (MC) simulation of lipid membranes. We provide an introduction...... into the various move sets that are implemented in current MC methods for efficient conformational sampling of lipids and other molecules. In the second part, we demonstrate for a concrete example, how an atomistic local-move set can be implemented for MC simulations of phospholipid monomers and bilayer patches...

    In neutral radiation transport problems (neutrons, photons), two values are important: the flux in the phase space and the density of particles. To solve the problem with Monte Carlo method leads to, among other things, build a statistical process (called the play) and to provide a numerical value to a variable x (this attribution is called score). Sampling techniques are presented. Play biasing necessity is proved. A biased simulation is made. At last, the current developments (rewriting of programs for instance) are presented due to several reasons: two of them are the vectorial calculation apparition and the photon and neutron transport in vacancy media [fr

  13. MBR Monte Carlo Simulation in PYTHIA8

    Science.gov (United States)

    Ciesielski, R.

    We present the MBR (Minimum Bias Rockefeller) Monte Carlo simulation of (anti)proton-proton interactions and its implementation in the PYTHIA8 event generator. We discuss the total, elastic, and total-inelastic cross sections, and three contributions from diffraction dissociation processes that contribute to the latter: single diffraction, double diffraction, and central diffraction or double-Pomeron exchange. The event generation follows a renormalized-Regge-theory model, successfully tested using CDF data. Based on the MBR-enhanced PYTHIA8 simulation, we present cross-section predictions for the LHC and beyond, up to collision energies of 50 TeV.

    Cazenave, Tristan; Saffidine, Abdallah

    Monte-Carlo Tree Search (MCTS) is a successful algorithm used in many state of the art game engines. We propose to improve a MCTS solver when a game has more than two outcomes. It is for example the case in games that can end in draw positions. In this case it improves significantly a MCTS solver to take into account bounds on the possible scores of a node in order to select the nodes to explore. We apply our algorithm to solving Seki in the game of Go and to Connect Four.

    Random walks have been used to calculate the energies of the ground states in systems of N=3, 6, 9, 12 quarks. Multiquark states with N>3 are unstable with respect to the spontaneous dissociation into color singlet hadrons. The modified Green's function Monte Carlo algorithm which proved to be more simple and much accurate than the conventional few body methods have been employed. In contrast to other techniques, the same equations are used for any number of particles, while the computer time increases only linearly V, S the number of particles

    2017-01-01

    Sampling from the posterior distribution using Markov chain Monte Carlo (MCMC) methods can require an exhaustive number of iterations to fully explore the correct posterior. This is often the case when the posterior of interest is multi-modal, as the MCMC sampler can become trapped in a local mode for a large number of iterations. In this paper, we introduce the pseudo-extended MCMC method as an approach for improving the mixing of the MCMC sampler in complex posterior distributions. The pseu...

  19. Diffusion quantum Monte Carlo for molecules

    International Nuclear Information System (INIS)

    Lester, W.A. Jr.

    1986-07-01

    A quantum mechanical Monte Carlo method has been used for the treatment of molecular problems. The imaginary-time Schroedinger equation written with a shift in zero energy [E/sub T/ - V(R)] can be interpreted as a generalized diffusion equation with a position-dependent rate or branching term. Since diffusion is the continuum limit of a random walk, one may simulate the Schroedinger equation with a function psi (note, not psi 2 ) as a density of ''walks.'' The walks undergo an exponential birth and death as given by the rate term. 16 refs., 2 tabs

    Full Text Available Parasitic infections caused by intestinal protozoan and helminths affect more than two billion people worldwide and chemotherapy is the most commonly used therapeutic procedure. Considering the problems created by parasitic infections and the incorrect use of drugs, the aim of this work was to detect the frequency of enteroparasites infection and to estimate the use of chemotherapeutic agents in children living in the periphery of the city of Porto Alegre, RS, Brazil. Ninety-six preschool age children, who had parasitological exams and who used antiparasitic drugs, were analyzed. The efficacy of treatment was evaluated by stool examination repeated six months after treatment. The same diagnostic test was used to evaluate parasitological cure, which was defined as absence of eggs and cysts in the stool. From these children, 79 (82.3% were contaminated by some species of parasite, the most prevalent were Ascaris lumbricoides, Trichuris trichiura and Giardia lamblia. The most commonly used drugs were mebendazole (86% of prescriptions and metronidazole (30.3%. The cure rate in the 79 children, examined 6 months after treatment, was 65.3% for A. lumbricoides and 66.1% for T. trichiura. This study suggests that a continuous education program regarding the prevention and treatment of parasitic infections is an essential tool for their eradication.

Neste contexto, abordamos os conflitos que ocorrem, há mais de cinco anos, pela definição de quem pode usar o espaço de um centro comercial e sua vizinhança, em Porto Alegre. As informações foram obtidas de fontes secundárias, entrevistas e observação não-participante. A análise indicou que a estratégia do centro comercial se orientou pelo consumo da diferença. No entanto, quando o público de homossexuais de classe média foi substituído por um público mais jovem e com menor poder aquisitivo, passaram a ocorrer episódios de violência por parte de seguranças e da Brigada Militar. Propomos articular identidade sexual, classe social e consumo com as noções de espaço e território, de modo a compreender as ações sociais destes jovens que, indesejados em um território de consumo, produzem um território de luta.

    Full Text Available Com o objetivo de avaliar a qualidade da água superficial da Sub-bacia Hidrográfica do Córrego Horizonte, Alegre, ES, foram coletadas amostras de água para análise físico-química em diferentes locais da sub-bacia estudada, cada uma sob influência de diferentes usos do solo: pastagem, floresta e cafeicultura. As coletas foram realizadas duas vezes ao ano, uma no período de estiagem e outra no período de chuvas. De acordo com os resultados encontrados todas as amostras de água apresentaram-se em conformidade com a legislação, apenas para o fósforo total e ferro foram observados valores acima do máximo permitido. O que demostra que uma pastagem e cultivo agrícola (cafeicultura quando bem manejados, adotando todos os princípios de conservação do solo, podem manter uma água de boa qualidade, como a encontrada em áreas florestadas.

    Full Text Available This article describes the socio-environmental conflicts around the logics of occupation at Morro do Osso (Bone’s Hill in Porto Alegre, Brazil. Disputes involving different types of appropriation, use and significance of this area have been motivating actions of quite heterogeneous institutions and social organizations. Since the late 70’s, environmentalists who were concerned about the growing urbanization mobilized to ensure the hill’s preservation, a process that culminated on the creation of Morro do Osso Natural Park. Ten years later, in 2004, Kaingang indigenous people began to claim the demarcation of an indigenous land at Morro do Osso on an area that overlaps the Park. Thus, two territorialities emerged and began to polarize the conflict: on the one hand, those who favor maintaining the Morro do Osso Natural Park institutionalization; on the other hand, efforts for the Topë pën Kaingang’s land recognition and demarcation. Therefore, precisely the resulting tensions and implications of this polarization will be discussed here in order to bring out part of the discursive arena and the consequences of this territorial dispute, that, to date, has been demonstrating nothing dialogical and no prospect of consensus agreement between the parties involved, following a logic of “winners and losers” to the outcome of the dispute.

    Full Text Available This paper presents the results of research in an interorganizational network of urban public transportation on the electronic ticketing system developed by the Association that links public transportation companies in the metropolitan Porto Alegre. The methodology includes a qualitative analysis of poorly known and - defined variables characterized by intangibles, which inhibit the formulation of hypotheses, as well as considering the complex aspects that make up the organizational setting. The data were obtained from secondary data registered in documents and primary data from interviews with managers of the associated firms, and were systematically analyzed by content. The interviewees for this study were the executive manager of the Transportation Association, the information technology coordinator of the management consortium, the project coordinator and the director of transportation for the managing company. The results of the interviews were classified into categories, creating interlinking information on each theme proposed in the initial categories. The results suggest that the electronic ticketing system constitutes an innovation produced from operational improvements in control and structural processes in the associated companies. The stimuli for innovation and the formation of the association include cost and risk sharing, economies of scale through working in a network, public pressure for improvement without increase of costs, loss of income caused by alternative means of transportation and the requirement for high levels of finance, technology and staff, which would be unviable in individual companies.

    Full Text Available While studying the booksellers’ training ritual that takes place in the larger ritualized context of the Porto Alegre Book Fair, this article attempted to analyze the work conditions of book sellers during the Fair, as well as to identify the reasons behind their commitment or non-commitment with the event’s success. The hierarchical structure found in the local daily context is also present during the Fair; however, training focuses on the praise of knowledge, culture and working people. Therefore, employees are encouraged to overlook any possibilities of criticizing work conditions in favor of the satisfaction to participate in such event. The ethnographic method, with participative observation techniques and interviews, was considered the most effective to analyze this space. Results indicate that when a ritualistic connotation is given to training, marketing aspects are neglected and emphasis is placed on the pleasure of festive events and the sociability propitiated. Thus, in spite of poor work conditions, booksellers give up even their basic needs so as to “delight” clients and, as a consequence, to sell better
