    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.

    Full Text Available ResumoUnidades de conservação de proteção integral buscam a manutenção dos ecossistemas livres de alterações causadas por interferência humana, admitindo apenas o uso indireto de seus recursos naturais. Portanto, este trabalho estudou a dinâmica do uso e cobertura da terra na unidade de conservação de proteção integral Parque Estadual Monte Alegre (PEMA do município de Monte Alegre (PA, bem como sua respectiva Zona de Amortecimento, para avaliar a efetividade de sua criação como iniciativa de preservação da biodiversidade local. Foram avaliados produtos de sensoriamento remoto dos anos de 1990, 2001 e 2011, sendo 2001 o ano de criação da unidade em estudo. O resultado permite afirmar que a criação da unidade de conservação PEMA foi importante, uma vez que ao observar dados referentes a dez anos de unidade percebe-se a diminuição do desflorestamento quando comparado ao período anterior à sua implantação. Porém, do ponto de vista conservacionista, tal resultado não é satisfatório, já que fatores que ameaçam a integridade biológica das áreas protegidas não deveriam ocorrer após sua criação. Medidas de proteção mais adequadas devem ser tomadas visando atingir o objetivo da unidade de conservação.

  6. Evaluation of 222Rn concentration of the internal and external environments of residences at Monte Alegre municipality, Para, Brazil

    International Nuclear Information System (INIS)

    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 222Rn, 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 222Rn in the residences of Monte Alegre and CANP. Determinations of the 238U and 226Ra 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. m3 (action level) and 600 Bq. m3 (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.

  9. Evaluation of chromosome aberration frequency instable in individual groups residents at the municipality of Monte Alegre, Para, Brazil, exposed to radon

    International Nuclear Information System (INIS)

    The municipality of Monte Alegre is a region that presents natural radiation high due to the presence of the radionuclide uranium (238U) 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

    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.

    Uranium is a natural radioactive metallic element; its effect on the organism is cumulative, and chronic exposure to this element can induce carcinogenesis. Three cities of the Amazon region-Monte Alegre, Prainha, and Alenquer-in North Brazil, are located in one of the largest uranium mineralization areas of the world. Radon is a radioactive gas, part of uranium decay series and readily diffuses through rock. In Monte Alegre, most of the houses are built of rocks removed from the Earth's crust in the forest, where the uranium reserves lie. The objective of the present work is to determine the presence or absence of genotoxicity and risk of carcinogenesis induced by natural exposure to uranium and radon in the populations of these three cities. The frequency of micronuclei (MN) and chromosomal aberrations (CA) showed no statistically significant differences between the control population and the three study populations (P > 0.05). MN was also analyzed using the fluorescence in situ hybridization (FISH) technique, with a centromere-specific probe. No clastogenic and/or aneugenic effects were found in the populations. Using FISH analysis, other carcinogenesis biomarkers were analyzed, but neither the presence of the IGH/BCL2 translocation nor an amplification of the MYC gene and 22q21 region was detected. Clastogenicity and DNA damage were also not found in the populations analyzed using the alkaline comet assay. The mitotic index showed no cytotoxicity in the analyzed individuals' lymphocytes. Once we do not have data concerning radiation doses from other sources, such as cosmic rays, potassium, thorium, or anthropogenic sources, it is hard to determine if uranium emissions in this geographic region where our study population lives are too low to cause significant DNA damage. Regardless, genetic analyses suggest that the radiation in our study area is not high enough to induce DNA alterations or to interfere with mitotic apparatus formation. It is also possible that

    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. This study gathered information and molecular epidemiology for risk assessment of cancer in the population of Monte Alegre. (author)

    Full Text Available Recentemente, o transplante renal passou a ser uma modalidade terapêutica aceita para o tratamento de pacientes renais crônicos terminais infectados pelo HIV. Para tal, há necessidade de estabilidade de parâmetros clínicos e laboratoriais relacionados à infecção pelo HIV e do uso de terapia antiretroviral de elevada eficiência. Neste relato, apresentamos os dois primeiros casos no Brasil de pacientes portadores de infecção pelo HIV transplantados com órgãos de doadores falecidos realizados com sucesso em nossa instituição. As interações entre os imunossupressores e as drogas antiretrovirais, as coinfecções, o perfil de risco cardiovascular e a elevada incidência de rejeição aguda permanecem os maiores problemas a serem equacionados nestes pacientes.

    Full Text Available No artigo são descritas e comparadas as atividades externas de dois atores subnacionais de níveis de governo diferentes: a prefeitura de Porto Alegre (nível local e o governo estadual do Rio Grande do Sul (nível regional. Os dois atores considerados têm desenvolvido uma atividade externa destacável e pioneira no contexto brasileiro. O núcleo do artigo é a descrição e a comparação das dimensões institucional (estrutura paradiplomática e substancial (agenda e instrumentos dos dois governos subnacionais. Nosso principal objetivo é contribuir, a partir da análise desses casos concretos, para a conceituação diferenciada dos governos locais e dos regionais como atores internacionais. Tanto uns como outros podem ser considerados atores internacionais mistos, em parte condicionados pela soberania que compartilham com os outros níveis de governo no território que administram, mas também mais livres que os governos centrais no que diz respeito a suas opções de política exterior, com alguns pontos de atuação semelhantes às dos atores não estatais. Nossas perguntas de partida são como os dois tipos de atores conjugam as características próprias dos atores condicionados pela soberania e as dos livres e se há diferenças significativas entre a ação encaminhada nesse sentido pelos governos locais e pelos regionais.In this article we compare the external activities carried out by two subnational actors of different governmental levels: the Municipality of Porto Alegre (local government and the State of Rio Grande do Sul (regional government.

    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 The main objective of this paper is to present some of the practices that characterized the commercial exploitation of projected images in Porto Alegre, particularly that of magic lantern still images as shown in public projections between 1861 and 1908. By identifying the uses and associations that gave an impetus to this experience in two different settings - i.e. prior to and after the advent of cinema in the city (1896 - it is possible to observe how certain ways of showing and seeing have remained unchanged or evolved, as well as its implications for the constitution of modern visuality.

    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.

Os procedimentos foram: mensuração do grau de presença dos princípios da mentalidade enxuta na gestão das quinze empresas de transporte coletivo por ônibus de Porto Alegre; teste da confiabilidade das respostas e separação das empresas em aglomerados, segundo a intensidade da presença; e estudos de caso com os aglomerados extremos, a associação de classe e a operadora pública influente na indústria. Um achado dos casos é que a indústria tem capacidade de aprendizagem e aceitaria uma abordagem indutiva e prática, baseada em Benchmarking, com operações de fabricação de classe mundial, para modificação de seus modelos de gestão. Também emergiu que a indústria teria dificuldades com abordagens dedutivas formalizadas, que incluam atividades acadêmicas.This paper presents a research into the presence of Lean Thinking principles in the management of urban transport firms in Porto Alegre. The procedures were: measurement of presence of Lean Thinking principles in management of urban transportation firms in Porto Alegre; reliability checks and clustering of firms according to the degree of presence; and case studies with clusters, class association and a public operator who influences the industry. The research discovered that the industry has learning capacity and would welcome an inductive approach based on Benchmarking with world-class manufacturing operations, in order to enhance management. Also, the industry was less inclined to accept deductive approaches and academic activities in such a program.

A variedade neoformans, encontrada em fontes ambientais, incluindo fezes de pombos, é importante causa de mortalidade em indivíduos imunodeprimidos em todo o mundo. Contudo, ainda não há estudos sobre sua ecologia na cidade de Porto Alegre, onde se tem registro da ocorrência de casos humanos dessa micose. Para pesquisar fontes saprofíticas de C. neoformans na cidade de Porto Alegre, foram coletadas 88 amostras de excretas de pombos em distintas praças da cidade. Suspensões das amostras em salina estéril foram semeadas em placas com meio ágar Sabouraud e incubadas em estufa a temperaturas entre 29 e 30,5°C. Após cinco dias, colônias mucóides foram subcultivadas para identificação através de provas morfofisiológicas. O fungo C. neoformans foi isolado em 88 (100% das amostras avaliadas, confirmando sua ocorrência nos pombos que habitam as praças da cidade.Cryptococcus neoformans is an encapsulated yeast, causing cryptococcosis in human beings and animals.

    A quantitative microbiology risk assessment was conducted to evaluate the risk of Salmonella infection to consumers of fresh pork sausages prepared at barbecues in Porto Alegre, Brazil. For the analysis, a prevalence of 24.4% positive pork sausages with a level of contamination between 0.03 and 460 CFU g(-1) was assumed. Data related to frequency and habits of consumption were obtained by a questionnaire survey given to 424 people. A second-order Monte Carlo simulation separating the uncertain parameter of cooking time from the variable parameters was run. Of the people interviewed, 87.5% consumed pork sausage, and 85.4% ate it at barbecues. The average risk of salmonellosis per barbecue at a minimum cooking time of 15.6 min (worst-case scenario) was 6.24 × 10(-4), and the risk assessed per month was 1.61 × 10(-3). Cooking for 19 min would fully inactivate Salmonella in 99.9% of the cases. At this cooking time, the sausage reached a mean internal temperature of 75.7°C. The results of the quantitative microbiology risk assessment revealed that the consumption of fresh pork sausage is safe when cooking time is approximately 19 min, whereas undercooked pork sausage may represent a nonnegligible health risk for consumers.

  1. The Porto Alegre paradox: social determinants and tuberculosis incidence

    Full Text Available INTRODUCTION: The incidence of tuberculosis (TB is strongly associated with social and economic factors. The city of Porto Alegre, in the South of Brazil, has one of the highest Human Development Index and Gross Domestic Product per capita of the country. One would expect that the incidence of tuberculosis in such a place were low. However, the city has very high rates of incidence, the highest among Brazilian capitals. This paradox prompted this work, whose objectives were to analyze the spatial distribution of the incidence rate of bacilliferous pulmonary tuberculosis throughout the neighborhoods of Porto Alegre and its association with socioeconomic indicators. METHODS: Ecological non-concurrent cohort study. The units of analysis were the neighborhoods of the city. The average annual incidence of bacilliferous pulmonary tuberculosis for the period 2000 to 2005 and seven socioeconomic variables were analyzed, with information obtained from the IBGE and the Mortality Information System. Spatial techniques and multivariate analyzes were used to check associations. Inequalities were also measured. RESULTS: The spatial distribution of the incidence rate of bacilliferous pulmonary tuberculosis is very similar, i.e., associated with the distribution of socioeconomic factors. The Relative Index of Inequality was 7.9, showing the great difference in the incidence rate between neighborhoods. CONCLUSION: Porto Alegre presents high incidence rates of bacilliferous pulmonary tuberculosis, which distribution through the neighborhoods of the city is associated with socioeconomic factors. The city's high rate is due to the extremely high incidence rates in its poorest neighborhoods. The authors raise hypotheses and suggest interventions.

    Full Text Available Early childhood caries is a persistent worldwide problem. The etiologic contribution of feeding practices has been less frequently investigated in prospective studies of young children. The Porto Alegre Early Life Nutrition and Health Study has followed a birth cohort of 715 mother-child pairs, recruited from municipal health centers, originally involved in a cluster-randomized controlled trial of healthcare worker training. The birth cohort links prospectively collected socio-demographic, infant feeding, and general and oral health information. To date, oral health data, including caries status and oral health-related quality of life, have been collected for 458 children at the age of 2-3 years. Studies are underway to investigate possible determinants and consequences of oral health among these children.

    2014-01-01

    Full Text Available This study aims to present the model of deliberative democracy, which Habermas envisioned to be a third way to modern models, be they liberal or communitarian. Habermas presents itself as the resolution of normative legitimation procedure, through the exercise of public reason, seeking compromise on the solution of social problems. This position requires a different form of proceduralism, based on intersubjective legitimacy of norms and institutions, according to their suitability for the reference of free deliberation. Given this, it aims to demonstrate ways in which Habermas's theory differs from modern models, as well as evaluating how would be able to generate social stability and reduce inequities. Finally, studies by the Center for Deliberative Democracy at Stanford University will be analyzed in an experiment conducted in the city of Porto Alegre / RS.

    Full Text Available Bullying é uma palavra inglesa que foi adotada em diversos países para se referir à intimidação. Brigas, ofensas, comentários maldosos, agressões físicas e psicológicas, repressão são tipos de violência geralmente associados à infância. Estudos indicam que brincadeiras de mau gosto podem gerar conseqüências sérias como baixa auto-estima, novas fontes de violência e, inclusive, casos de suicídio. Este estudo vem sendo desenvolvido desde julho de 2007 em quatro escolas publicas da cidade de Porto Alegre – RS, totalizando 192 alunos participantes. Através de questionário e grupos focais observou-se que mais de 70% dos alunos percebem a existência de preconceitos no ambiente escolar e quase 40% consideram regular/ ruim/ péssimo as relações na escola, refletindo o mal-estar do estudante em relação à escola.

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.This study was conducted to establish the frequency of hemoglobinopathies among newborns undergoing screening tests for metabolic diseases at the University Hospital (Hospital de Clínicas in Porto Alegre, Rio Grande do Sul, Brazil.

    This study aims at a broader understanding of the functioning of the health system from the perspective of economics, utilizing the tools made available by this area for evaluating an important public policy proposed by the Brazilian federal government: the Family Health Program. This first approach consists in a case study conducted in the city of Porto Alegre during the period 1998-2002. The purpose of this study was creating an instrument for the cost management of the program allowing for monitoring and redirecting actions when necessary. An extensive review of the literature was carried out and data about the work processes, the organizational structure of the secretariat in charge and cost and production of the program were collected for constructing the cost management instrument. The study showed no important variation in the total cost of the program during the period but considerable variations in some specific cost categories. Furthermore it was shown that different health units involve different costs related to the size of the team or to the target population.

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.

    A literatura sobre aquisições transnacionais sugere que certas mudanças nas práticas gerenciais nas empresas adquiridas refletem a herança administrativa da empresa adquirente e, conseqüentemente, a nacionalidade dessas empresas. O argumento deste artigo, ilustrado pela aquisição de uma empresa familiar brasileira por uma multinacional, é que a forma como o processo de integração é conduzido é determinante essencial para se compreender o tipo e a extensão das mudanças das práticas organizacionais no período pós-aquisição. Para analisar essas mudanças, foca-se especificamente o processo de gestão de pessoas na ABB – Montes Claros, desde o momento da aquisição, utilizando o modelo de múltiplos papéis de Ulrich (1999. Os resultados apontam para a confirmação da hipótese de que o tipo de mudança assim como a sua extensão devem-se mais à autonomia da empresa adquirida na condução do processo e à construção de práticas que refletem a competência gerencial local do que à herança administrativa ou às orientações corporativas da adquirente. Pôde-se, também, constatar o papel relevante da área de RH na integração pós-aquisição, reforçando a autonomia na relação entre adquirente/adquirida. Conclui-se, portanto, que, no contexto das aquisições transnacionais, a gestão de pessoas adquire novos contornos, passando a constituir um dos grandes desafios para os gestores nas empresas.

    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)

    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.

Foi realizada análise das práticas discursivas, inspirada nos conceitos de discurso de Foucault e nos estudos sobre ética e cuidado de si. 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.

Structural analysis of forest fragments in the Alegre River subwatershed, State of Espírito Santo, was based on landscape metrics using ArcGIS 10 software with Patch Analyst extension, regarding changes during 1975, 2002, and 2007. Analysis showed an increase of about 7% in the total area of forest cover and emergence of 645 new forest fragments. Numerous patches and a small drainage area resulted in a high perimeter-to-area ratio. Simple geometric shapes predominated in smaller patches ( 20 ha were close to each other, with a tendency to decrease proximity metric values. The results show that despite increase in vegetated area, the environmental quality of forest remnants is highly jeopardized.

    The untold story of the Maritime Maya from the ancient port site Vista Alegre, is being written for the first time using a multidisciplinary effort that aims to reconstruct the environmental and morphological history of the site. Vista Alegre is located on the north-eastern tip of the Yucatan peninsula, on the ancient Maritime Maya trade routes. This strategic point between the Caribbean Sea and the Gulf of Mexico, offers an ideal setting for this kind of research, which will add to the general Maritime Maya history. The multidisciplinary effort is part of a larger project called "Costa Escodida". The project's main goals are to learn how the ancient inhabitants adapted to the environment, and to understand how this coastal site was integrated into broader maritime trade routes. The portion of the research presented here concentrates on the sites geomorphology and climate during the past 2-3000 years through the multiproxy analysis of marine sediment core and surface samples combined with archaeological data. This study aids our understanding of the site's possible functions, the environmental challenges the local inhabits contended with, and the identification of ancient harboring locations. The site was inhabited from the 9th century B.C until the mid 16th century A.D., with an apparent two century abandonment phase from the mid 7th to 9th century A.D. According to the results, five depositional phases can be recognized, and the related shoreline reconstruction shows a general trend of a flooded terrestrial landscape. This 'flooding' relates well to relative sea-level curves published in the region. Continued analysis of results from the research, and future research activities, may make it possible to recognize hurricane proxies in the sediment, locate underwater manmade seafaring artifacts and facilities, determine the range of economic opportunities for past inhabitants and quantify the availability of potable water sources.

    Full Text Available ABSTRACTKnowledge of soil characteristics in areas where activities related to the environment are developed, such as Porto Alegre Botanical Garden (JB-PoA, is a fundamental condition for the sustainable use of this natural resource. 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.

    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 Participatory budgeting in Porto Alegre, Brazil is widely regarded internationally as one of the most significant innovations in participatory governance. Launched in the late 1980s, it has been credited with deepening political and social inclusion, enabling ordinary citizens to shape municipal budget policy and redistribute state resources. But since the mid-2000s, this initiative has experienced significant weakening under a series of conservative local governments, putting into serious question its sustainability amid inhospitable political conditions. This article advances an analytical framework to understand both the rise and subsequent weakening of participatory budgeting. By drawing together elements in the state, civil society and broader politico-institutional and economic environment, and showing how these changed over time, the paper provides an analytical account of the shifting fortunes of participatory budgeting in Porto Alegre.

    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 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.O estudo investiga o processo de tomada de decisão dos consumidores, suas atitudes e valores em relação ao alimento orgânico pelo uso da Teoria do Comportamento Planejado, adaptando a metodologia de um estudo da União Europeia. Foram entrevistados 450 consumidores em supermercados e feiras ecológicas em Porto Alegre, Brasil. Os resultados indicam um grande nível de penetração e uma atitude muito positiva em relação aos produtos orgânicos. Os entrevistados acreditam que os alimentos orgânicos são mais saudáveis, saborosos, mais naturais e ambientalmente corretos, apesar de serem menos atraentes visualmente e mais caros que alimentos convencionais.

    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

    2001-01-01

    Transition probabilities governing the interaction of energy packets and matter are derived that allow Monte Carlo NLTE transfer codes to be constructed without simplifying the treatment of line formation. These probabilities are such that the Monte Carlo calculation asymptotically recovers the local emissivity of a gas in statistical equilibrium. Numerical experiments with one-point statistical equilibrium problems for Fe II and Hydrogen confirm this asymptotic behaviour. In addition, the re...

  6. Fundamentals of Monte Carlo

    Wollaber, Allan Benton [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2016-06-16

    This is a powerpoint which serves as lecture material for the Parallel Computing summer school. It goes over the fundamentals of Monte Carlo. Welcome to Los Alamos, the birthplace of “Monte Carlo” for computational physics. Stanislaw Ulam, John von Neumann, and Nicholas Metropolis are credited as the founders of modern Monte Carlo methods. The name “Monte Carlo” was chosen in reference to the Monte Carlo Casino in Monaco (purportedly a place where Ulam’s uncle went to gamble). The central idea (for us) – to use computer-generated “random” numbers to determine expected values or estimate equation solutions – has since spread to many fields. "The first thoughts and attempts I made to practice [the Monte Carlo Method] were suggested by a question which occurred to me in 1946 as I was convalescing from an illness and playing solitaires. The question was what are the chances that a Canfield solitaire laid out with 52 cards will come out successfully? After spending a lot of time trying to estimate them by pure combinatorial calculations, I wondered whether a more practical method than “abstract thinking” might not be to lay it out say one hundred times and simply observe and count the number of successful plays... Later [in 1946], I described the idea to John von Neumann, and we began to plan actual calculations." - Stanislaw Ulam.

    Full Text Available ABSTRACT: The cultivation of mulberry ( Rubus sp. is highly disseminated in cold climates, but some cultivars adapt to warm weather environments. The objective of the present study was to evaluate the production of blackberry and redberry in season and off season in Pouso Alegre, south of Minas Gerais. The experimental design was a randomized block, with twelve cultivars ('Arapaho', 'Xavante', 'Brazos', 'Tupy' 'Comanche', 'Choctaw', 'Guarani', 'Caingangue', 'Cherokee', 'Chicasaw' and 'Clone' and a redberry, three blocks and an experimental unit of four plants with a spacing of 0.5x3.0m and a total density of 6,666 plants per hectare. Conventional pruning was performed to produce the crop (October-December and for off-season production (April-July. In 'Brazos' there was increased production in the two seasons evaluated against other mulberry trees, conversely, in the off season, there was a positive effect of pruning carried out in January only in 'Tupy', 'Choctaw', 'Comanche' and 'Clone', with 'Tupy' presenting the highest productivity off season. In 'Brazos' and 'Tupy' there was the best balance between soluble solids and acidity in the crop and red berry in season. 'Brazos' and 'Cherokee' had the highest average content of total sugars. Due to the lack of supply of fruit, pruning mulberry trees in January is an alternative to increase the income of family-based farms.

    2001-01-01

    Violence is of major importance in the health profile of Brazilian metropolitan areas and should be treated as a public health problem. Spatial analysis methods can be highly useful for the surveillance and prevention of violence. This paper analyzes the spatial distribution of victims' place of residence in relation to the main causes of violent death in Porto Alegre (1996) in order to identify vulnerable areas. For motor vehicle accidents, homicides, and suicide, the victim's place of residence was pinpointed using the municipal Geographic Information System. The point patterns of health events and population density were analyzed using a Kernel smoother, visually compared. Some areas with higher concentration of events are similar to population distribution but differ from each other in the remaining high concentration areas, thus indicating specific micro-areas at risk. Areas of higher homicide risk are mainly located on the periphery of the more urbanized area, with worse socioeconomic conditions. Motor vehicle accidents are concentrated in areas that are simultaneously commercial and residential and are traversed by streets with heavy traffic. Suicide deaths are more evenly distributed over the territory. Identification of risk areas provides meaningful information for developing preventive and health promotion measures focusing on the events for which health policies may play a central role.

    Full Text Available The control of erosion requires an understanding of the complex interactions between chemical, physical, hydrological and meteorological. Several mathematical models have been developed and improved in objective to predict the magnitude of soil loss by erosion, like the Water Erosion Prediction Project (WEPP. It was objectified with this work to evaluate the soil loss and water catchment in the Espírito Santo. To reach the proposed objectives was held to characterize the watershed area of stream Jaqueira located in the Alegre-ES city, and the lifting of the input files of the WEPP model (climate, soil, land use and management and topography. Finally, we applied the model to predict soil loss and water through the integration of softwares GeoWEPP, TOPAZ and ArcView. The obtained results allowed to conclude that: the current simulated average losses in the watershed of the stream Jaqueira are of 52.9 mm year-1 for the runoff and 17.5 t ha-1 yr-1.

    Full Text Available Six Sigma combines managerial factors with statistical tools and is deployed in many enterprises today. Rio Grande do Sul is a Brazilian state that has a great industrialization, especially in the metropolitan area of Porto Alegre. Some of these industries have deployed the Six Sigma program. The aim of this paper is to present characteristics of the Six Sigma program in companies located in this region, through an exploratory study. A literature review subsidized the development of the questionnaire. Eleven companies participated of research in July and August 2008. It used statistical tools and qualitative analysis to analyze the results. Most of the companies that participated is classified as large and uses the DMAIC method to implement Six Sigma. The principal cause of program implementation was process improvement. In only one company the Six Sigma is implemented in all sectors, including administrative areas. Another result is the lack of clearly criteria for defining the career of Belts and the discrepancy of academic formation of these specialists.

    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.

    This article deals with groups as an assistential modality used by the services of basic health attention. Workshops, health education groups, as well as, lectures are different activities done in relation to other traditional attendances. The study that is behind this discussion had as its main aim to know the profile of assistance, under groups' organization, offered in the Units which make part of the Basic Health Network in Porto Alegre. Within a total of 124 health services, 116 professionals were approached, among them, 96 developed groups. We could verify that the groups have therapeutic relevance because they favor the sharing of information and the learning about aspects which are related to the topic health-sickness. They constitute inclusive practices, which are able to create a link with the users and the service, as well as, to reformulate the existing assistential model. Therefore, it was verified that the understanding of these practices reflects on its dimension of the group assistance qualification and also the strategic dimension of compensation in the attendance of the increasing demand of health.

    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 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.

  3. Petrochemical characteristics of Serra do Meio alkaline granite (Campo Alegre de Lourdes - Bahia State)

    International Nuclear Information System (INIS)

    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 SiO2-enrichment (67 to 76%), in alkalis (Na2+K2O, 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)

Data on sanitization procedures and physical structure of barns, source and treatment of water, hygiene practices and health status of milkers, udder cleaning and disinfection procedures and sanitary control of the herd was collected. The physical structure of the locations of the tanks was also assessed. The barns were ventilated, protected from moisture and had covers, and few had cemented floor and milking parlor. A low percentage of producers performed pre (21% and post (6% dipping procedures. Only 1/4 of the farmers used the mug test. All equipment and tools were washed after milking, but few farmers (5% used sanitizers and 94% of the farms used untreated water. Only 8% of the milkers had the habit of washing their hands before milking, and 9% of them were aware of IN 62 regulation of the Ministry of Agriculture, Livestock and Supply. None of the facilities had protection against the entrance of insects, rodents and environmental contaminants. They were poorly sized, did not allow the application of adequate sanitary measures and sanitary conditions were deficient. The high level of nonconformities regarding good manufacturing practices for milk production reinforced the need for the implementation of Good Agricultural Practices in rural farms for the purpose of obtaining milk produced according to the quality standards, preventing losses and ensuring the sustainability of dairy production in the region.

    Full Text Available OBJETIVO: Verificar a prevalência da exposição à violência sexual entre adolescentes estudantes de escolas estaduais. MÉTODOS: Foram selecionadas 52 escolas estaduais de Porto Alegre, RS, Brasil, com ensino fundamental completo, por meio de um processo de amostragem aleatória, estratificada de acordo com o tamanho das escolas. Foi selecionada, em cada escola, uma turma de oitava série por sorteio aleatório e foram incluídos todos os adolescentes presentes nas salas de aula que consentiram em participar do estudo. Foi utilizado o instrumento Triagem da Exposição de Crianças à Violência na Comunidade para identificar jovens que foram vítimas, testemunhas ou que conheciam vítimas de atos de violência sexual. RESULTADOS: Foram incluídos 1.193 adolescentes, representando 10,3% dos alunos matriculados na oitava série da rede estadual da cidade. Vinte e sete (2,3% adolescentes relataram ter sido vítimas de violência sexual, 54 (4,5% ter sido testemunhas de algum tipo de violência sexual e 332 (27,9% relataram conhecer alguém que tenha sido vítima de violência sexual. CONCLUSÕES: A exposição à violência sexual pelas três formas de contato relatadas mostrou-se freqüente entre os adolescentes estudados. São necessários estudos que abordem a violência sexual como um fenômeno social amplo, com múltiplos fatores associados, amparando estratégias comunitárias de prevenção e de tratamento.

    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. PMID:23657487

    At the northeast tip of the Yucatan Peninsula - where the Caribbean meets the Gulf - lies the ancient Maya port site of Vista Alegre. The inhabitants of this site, much like the people living nearby today, were forced to contend with the challenging coastal environment of Laguna Holbox. The sediment-rich, low gradient of the north coast presents a contrasting landscape compared to the Caribbean coast, where water resources are of much larger magnitude and evident in the extensive systems of cenotes (sinkholes) and underground rivers that supported pre-Columbian sites along this eastern rocky sediment-poor coastline. For past inhabitants the north coast was a mosaic of low-lying, non-arable zones where access to potable water was a challenge for inhabitants well into the 20th century. By bringing together scholars from the fields of archaeology, coastal ecology, geoarchaeology, and hydrogeology, the Proyecto Costa Escondida is focusing on the dynamic relationship between the Maya and their coastal landscape over the past 3000 years. To date we have collected 12 manual push-cores from the shallow waters surrounding Vista Alegre, which have been analyzed at 1 cm resolution using standard methods for Loss on Ignition (LOI), δ18Ocarb and δ13Ccarb of bulk carbonate, granulometry, micropalentology, and AMS radiocarbon dating. In addition to have baseline comparative data, we have conducted near-shore and terrestrial coastal ecological surveys along with the mapping of coastal water salinity and temperatures in the dry and wet seasons. Overall, the chemical proxies, lithology, and paleosalinity model reconstructed to date reveal four onlapping parasequences representing an overall transgression of the coastline with strong seasonality of water chemistry that has been changing under the control of rising sea levels over the past 3000 years. The sedimentation rate and timing of the transition to marine is in reasonable agreement with local sea level curves meaning that the

    This article discusses the perceptions of professionals and users about counselling practices at a counselling and testing centre in Porto Alegre/RS based on interviews with 27 service users and 14 members of the staff. The following categories emerged from thematic analysis: professionals' perceptions on counselling, users' perceptions on counselling and changes in counselling due to the introduction of rapid test procedures. The results show that, although initially there were some imprecision and apparent contradictions in its use, rapid testing was considered an invitation to rethink practices, bringing service closer to users' needs.

Ao longo de 2007 e 2008, foram mapeados os filmes produzidos e exibidos em Porto Alegre, em diferentes formatos e suportes, e após foi feita a análise do corpus conforme as categorias propostas no projeto geral da pesquisa. O objetivo era compreender como a cidade era percebida e representada nas imagens audiovisuais cinematográficas. Na análise, observamos a estética visual e sonora, a estrutura narrativa e as principais temáticas. A cidade que surge nas telas de cinema com certeza é muito diferente do imaginário que existe sobre a cidade real. Ao invés de uma grande metrópole moderna, o que se percebe é uma cidade que mal consegue sair dos seus limites oitocentistas.

Para ello, esta entidad multilateral ha apelado a distintas fórmulas políticas tendientes al encausamiento de problemáticas y conflictos apartados del camino de la institucionalidad y de los medios tradicionales de resolución. Con todo, y pese a la búsqueda de caminos alternativos, han sido las cumbres presidenciales la principal herramienta destinada a encontrar soluciones innovadoras y respetuosas del orden democrático y constitucional de los países sudamericanos. En este artículo se analiza de manera específica la actuación de la unasur en dos casos de profunda gravedad institucional: el intento de golpe de Estado ocurrido en Ecuador el 30 de septiembre de 2010 y el derrocamiento del ex presidente Fernando Lugo en Paraguay en junio de 2012. Luego de analizar estos dos casos extremos, y las implicancias políticas generadas, se avanza en una visión comprensiva acerca del éxito o el fracaso del papel político de la unasur como instancia de resolución de conflictos a nivel internacional.

    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...

    The Monte Carlo method is widely used to numerically predict systems behaviour. However, its powerful incremental design assumes a strong premise which has severely limited application so far: the estimation process must combine linearly over dimensions. Here we show that this premise can be alleviated by projecting nonlinearities on a polynomial basis and increasing the configuration-space dimension. Considering phytoplankton growth in light-limited environments, radiative transfer in planetary atmospheres, electromagnetic scattering by particles and concentrated-solar-power-plant productions, we prove the real world usability of this advance on four test-cases that were so far regarded as impracticable by Monte Carlo approaches. We also illustrate an outstanding feature of our method when applied to sharp problems with interacting particles: handling rare events is now straightforward. Overall, our extension preserves the features that made the method popular: addressing nonlinearities does not compromise o...

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

    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.

    Full Text Available Ecological parameters such as trophic niche overlap and niche breadth were computed from the frequency of all drosophilid species collected in 2001 and 2002, in the urban area of Porto Alegre city, Brazil. Independently of place, drosophilids community composition and components breeding or feeding sites, the highest frequencies of Zaprionus indianus (Gupta, 1970 were obtained during seasons with higher average temperatures, especially during summer. From a total of the 19,146 individuals of Z. indianus sampled, 80% were found in this season. The data of trophic niche breadth suggest a higher opportunism of adult flies in feeding substrate use, but the females are still selective in oviposition substrate choice. For the values of niche overlap, only for some species, did we find any correlation between these and species richness and/or number of resources, and the most of the correlation values considering breeding and feeding sites were positive. The colonization of Z. indianus in Porto Alegre could be leading to adjustments in the survival strategies of the resident species, but it is possible that many species have conditions for coexisting with the invader.Parâmetros ecológicos tais como sobreposição e amplitude de nicho trófico foram aplicados a partir da freqüência de todas as espécies de drosofilídeos coletados em 2001 e 2002 na área urbana da cidade de Porto Alegre, Brasil.

    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.

Informações sobre o animal, tais como raça, sexo, idade, acesso ou não à rua e tipo de alimentação, foram avaliadas por meio de questionário epidemiológico e análise estatística para correlacionar com os resultados obtidos na sorologia. Os resultados dos testes mostraram que os valores encontrados foram de 26,9% (HAI e 37,9% (IFI, inferindo que esses gatos em algum momento de sua vida foram fonte de contaminação ambiental, sendo eliminadores potenciais de oocistos, principalmente aqueles que tiveram livre acesso à rua.The sera of 245 cats from Porto Alegre, southern Brazil, were tested by indirect hemagglutination (IHA and indirect immunofluorescence (IIF in order to determine the frequency of Toxoplasma antibodies. Information such as breed, sex, age and access or not to the street and dietary habits were assessed using an epidemiological questionnaire and also statistical analysis for correlation with the serological results obtained. The test results showed rates of 26,9 and 37,9% for IHA and IIF, respectively, suggesting that these cats have acted as a source of environmental contamination at some time during the course of their lifetime, possibly shedding oocysts, especially those with free access to the street.

    This thesis considers several different techniques for optimizing Monte Carlo simulations. The Monte Carlo system used is Penelope but most of the techniques are applicable to other systems. The two mayor techniques are the usage of the graphics card to do geometry calculations, and raytracing. Using graphics card provides a very efficient way to do fast ray and triangle intersections. Raytracing provides an approximation of Monte Carlo simulation but is much faster to perform. A program was ...

    2015-01-01

    The article analyzes the flow of penal sensitivities in relation to medical and health care provided to prisoners in Porto Alegre Prison between 1855 and 1888. The internalization and the instrumentalization of concepts such as "humanity" and "civilization," especially by those individuals involved directly or with strong chances of influencing changes pertaining to penal issues, are observed. Indeed, in addition to generating favorable public opinion, the concerns of governing authorities and leading lights led to the development of concrete measures and practices that increased the minimum subsistence offered to the imprisoned class. This process, however, was far from linear and harmonic as witnessed by the diseases and the precariousness of prison life. PMID:26331647

    This study focuses on users' views of factors influencing quality of care at a health care unit in the city of Porto Alegre, relating to access and receptivity. The data were collected using a semi-structured interview and participatory observation and treated using thematic analysis. The results compare ease and difficulties in geographic, economic, and functional access. Organization of services and professional competency were determinant factors in ease of reception, leading to user satisfaction. Poor reception and unsatisfactory professional performance were identified as difficulties. The study concluded that there is a need to increase the professional staff, train them in receiving users, implement a complementary modality for dental care, open the facility earlier for scheduling appointments, and prioritize care for residents of the catchment area.

This work represents an attempt to renew decadent scholasticism, with the new methods of positive and historical theology. What makes this text original and interesting is its dialogue with the Enlightenment philosophers. The description of the content and, above all, the study of the sources he relied on, shows a man of wide reading and points to an ambience of cultural renewal that permeated the cultural life of the Viceroyalty of New Spain. It also reflects the intellectual environment of the Jesuits who settled in Italy after the expulsion and suppression of the Society of Jesus.

  17. Monte Carlo techniques

    International Nuclear Information System (INIS)

    The course of ''Monte Carlo Techniques'' will try to give a general overview of how to build up a method based on a given theory, allowing you to compare the outcome of an experiment with that theory. Concepts related with the construction of the method, such as, random variables, distributions of random variables, generation of random variables, random-based numerical methods, will be introduced in this course. Examples of some of the current theories in High Energy Physics describing the e+e- annihilation processes (QED, Electro-Weak, QCD) will also be briefly introduced. A second step in the employment of this method is related to the detector. The interactions that a particle could have along its way, through the detector as well as the response of the different materials which compound the detector will be quoted in this course. An example of detector at LEP era, in which these techniques are being applied, will close the course. (orig.)

    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 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.

Therefore, it focuses on the pictorial, historical and literary intertextuality of the film, emphasizing also the scenes in which the cinematographic technique reveals contents. The director’s ideology, that can be traced back from his “autobiography”, Mon dernier soupir, is also considered, as well as its reflection in the film. Finally, the paper addresses Buñuel’s connection with the surrealist movement and how all these circumstances affect to his interpretation, his parody of the History of Christianity, and also his conception of Christian religion. Keywords: Buñuel, Simón del desierto, Egyptian monasticism, Christianity, intertextuality, surrealism. // Resumen: En este artículo se comenta pormenorizadamente la película Simón del desierto de Luis Buñuel, atendiendo a fuentes referentes al monacato egipcio y aludiendo a obras conocidas por el director, así como a la intertextualidad pictórica, histórica y literaria de la película, destacándose además los casos en los que la técnica cinematográfica refuerza los contenidos. Se contempla también para su análisis la ideología que se trasluce en la “autobiografía” del autor, Mon dernier soupir, y que se refleja en el film, así como su conexión con el movimiento surrealista y en cómo afecta todo ello a su interpretación y parodia de la historia del cristianismo y a su propia concepción de la religión cristiana.

    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.

O objetivo deste estudo histórico foi identificar que representações das mulheres nas práticas equestres em Porto Alegre foram produzidas pela Revista do Globo no período de sua publicação. Realizou-se uma análise de conteúdo das reportagens da revista acerca destas práticas. As reportagens sugerem duas imagens sobre as mulheres no contexto das práticas equestres: no turfe, a presença feminina é limitada à assistência, associada à elegância, à fragilidade; no hipismo, as mulheres competem com igualdade com os homens, alcançando vitórias. Este olhar remete à análise do contexto sociocultural e político-econômico porto-alegrense que sustentou tais práticas equestres, cada qual reservando à mulher distintas possibilidades de atuação. Tais representações construídas pela revista podem resultar das distintas origens históricas e étnico-culturais do turfe e do hipismo.Turf and show jumping are topics diffused by Revista do Globo magazine, edited in Porto Alegre, Rio Grande do Sul's capital state, from 1929 until 1967.

    Complex Adaptive Systems of Systems, or CASoS, are vastly complex ecological, sociological, economic and/or 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 pervasive interdependencies and attendant vulnerabilities to cascades in associated systems. Phoenix was initiated to address this high-impact problem space as engineers. Our overarching goals are maximizing security, maximizing health, and minimizing risk. We design interventions, or problem solutions, that influence CASoS to achieve specific aspirations. Through application to real-world problems, Phoenix is evolving the principles and discipline of CASoS Engineering while growing a community of practice and the CASoS engineers to populate it. Both grounded in reality and working to extend our understanding and control of that reality, Phoenix is at the same time a solution within a CASoS and a CASoS itself.

    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

    The structural framework and tectonic evolution of the sedimentary basins along the eastern margin of the South American continent are closely associated with the tectonic framework and crustal heterogeneities inherited from the Precambrian basement. However, the role of NW-SE and NNW-SSE structures observed at the outcropping basement in Southeastern Brazil and its impact over the development of those basins have not been closely investigated. In the continental region adjacent to the Campos Basin, we described a geological feature with NNW-SSE orientation, named in this paper as the Alegre Fracture Zone (AFZ), which is observed in the onshore basement and can be projected to the offshore basin. The main goal of this work was to study this structural lineament and its influence on the tectonic evolution of the central portion of the Campos Basin and adjacent mainland. The onshore area was investigated through remote sensing data joint with field observations, and the offshore area was studied through the interpretation of 2-D seismic data calibrated by geophysical well logs. We concluded that the AFZ occurs in both onshore and offshore as a brittle deformation zone formed by multiple sets of fractures that originated in the Cambrian and were reactivated mainly as normal faults during the rift phase and in the Cenozoic. In the Campos Basin, the AFZ delimitates the western side of the Corvina-Parati Low, composing a complex fault system with the NE-SW faults and the NW-SE transfer faults.

    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.

    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.

    Full Text Available Our goal was to compare the bird richness and composition among different urban green areas in the metropolitan region of Porto Alegre. Data on the composition of species in 14 green areas were collected from the literature. Similarity analysis (Jaccard’s was used to compare the areas in relation to bird composition. We used multiple regression analysis in addition to the stepwise method in order to establish whether bird richness in the urban green areas was influenced by the following factors: dimension, variety of habitats, area and distance of the nearest neighbor. Our data compilation registered 224 bird species in the consulted areas. Jaccard’s analysis showed that larger green areas are more similar in their composition of bird species than smaller ones. Multiple regression analysis demonstrated positive correlations between bird richness and the analyzed factors (except for distance between areas. We concluded that, despite the importance of small green areas to certain bird species, larger ones with higher habitat heterogeneity are able to support significant bird richness, and that these areas are important to the maintenance of many bird species in urban areas.

    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.

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.

    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.

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.

    A produção de leite apresenta grande expressão econômica, sendo uma das grandes geradoras de emprego no meio rural brasileiro. No entanto, as pequenas propriedades leiteiras possuem dificuldades de se estabelecerem, diante das exigências impostas pelo mercado. A busca pela qualidade na cadeia produtiva do leite no Brasil tem gerado grandes debates. A Instrução Normativa nº. 51 (IN nº. 51, do Ministério da Agricultura, Pecuária e Abastecimento, instituiu regulamentos técnicos, fixando condições e requisitos mínimos higienico-sanitários para a obtenção e produção da matéria-prima. Este trabalho objetivou analisar os aspectos higiênico-sanitários na obtenção do leite no Assentamento Alegre, município de Araguaína, TO, verificando se o leite produzido obedecia aos padrões da IN nº. 51. Os dados utilizados são de natureza primária e foram obtidos mediante entrevistas diretas realizadas com 41 produtores rurais, em março de 2007. Os resultados obtidos mostram que as normas da IN nº. 51 não estavam sendo respeitadas em relação ao manejo empregado na ordenha, no que diz resepeito à higienização do ordenhador e dos utensílios. Verificou-se, além disso, que parte do leite produzido era entregue nos laticínios dentro dos prazos estabelecidos pela legislação. No entanto, a obtenção do leite precisa ser melhorada para que se possa adequar às exigências da IN nº. 51.

    Users' satisfaction is an important end-point to evaluate health services. This study has to do with an assessment of the level of user's satisfaction with relation to the last visit held in the primary health care network of Porto Alegre — RS, whose objective is to compare satisfaction of the users that assess the quality of the care process received as being of high APS score with that of the users who evaluate it as low APS score. A cross-sectional study based on the population, using the Primary Care Assessment Tool - PCATool, which enables the classification of the health services at the level of guidance to APS by means of the general score of primary care, defining it as high or low, in accordance with the users' experience. The satisfaction of the user was measured by a questionnaire consisting of twelve questions relative to the last visit, being measured by a 5-item Likert scale: "very good", "good", "regular", "bad" and "very bad". For the analysis, the results were grouped into two classifications, i.e. "satisfied", when referred as "veg good" or "good", and "dissatisfied" when referred to any of the other items. A significant difference was noticed in the 12 variables reflecting satisfaction in several aspects of the visit, showing higher satisfaction in users that classified the service as being of high score. The .general evaluation of the service presented 95.6% and 73.5% of "satisfied" in the services with high and low APS score, respectively (p<0.001. Users of services with high level of guidance to primary care obtain higher satisfaction in their visits. This higher satisfaction can benefit the decision-making process of the patient in face of the medical recommendations made.

    Observations by CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) have revealed a range of minerals in Libya Montes including olivine, pyroxene, and phyllosilicate [1]. Here we extend our spectral analyses of CRISM images in Libya Montes to identify carbonates. We have also performed detailed characterization of the spectral signature of the phyllosilicate- and carbonate-bearing outcrops in order to constrain the types of phyllosilicates and carbonates present. Phyllosilicate-bearing rocks in Libya Montes have spectral bands at 1.42, 2.30 and 2.39 µm, consistent with Fe- and Mg- bearing smectites. The mixture of Fe and Mg in Libya Montes may be within the clay mineral structure or within the CRISM pixel. Because the pixels have 18 meter/pixel spatial resolution, it is possible that the bands observed are due to the mixing of nontronite and saponite rather than a smectite with both Fe and Mg. Carbonates found in Libya Montes are similar to those found in Nili Fossae [2]. The carbonates have bands centered at 2.30 and 2.52 µm. Libya Montes carbonates most closely resemble the Mg-carbonate, magnesite. Olivine spectra are seen throughout Libya Montes, characterized by a positive slope from 1.2-1.8 µm. Large outcrops of olivine are relatively rare on Mars [3]. This implies that fresh bedrock has been recently exposed because olivine weathers readily compared to pyroxene and feldspar. Pyroxene in Libya Montes resembles an Fe-bearing orthopyroxene with a broad band centered at 1.82 µm. The lowermost unit identified in Libya Montes is a clay-bearing unit. Overlying this is a carbonate-bearing unit with a clear unit division visible in at least one CRISM image. An olivine-bearing unit unconformably overlies these two units and may represent a drape related to the Isidis impact, as suggested for Nili Fossae [2]. However, it appears that the carbonate in Libya Montes is an integral portion of the rock underlying the olivine-bearing unit rather than an

    Full Text Available OBJECTIVE: To identify the factors associated with aging of the socially-active elderly in the metropolitan region of Porto Alegre. 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. Family is the main social support system.OBJETIVO: Identificar fatores associados ao envelhecimento bem-sucedido de idosos socialmente ativos da Região Metropolitana de Porto Alegre.

A análise tem como base estudos desenvolvidos na Universidade Federal do Rio Grande do Sul, os quais discutem a existência de um projeto político-pedagógico para a referida rede de ensino que apresenta sintonia com a perspectiva da inclusão escolar. 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

  7. Kinematics of multigrid Monte Carlo

    International Nuclear Information System (INIS)

    We study the kinematics of multigrid Monte Carlo algorithms by means of acceptance rates for nonlocal Metropolis update proposals. An approximation formula for acceptance rates is derived. We present a comparison of different coarse-to-fine interpolation schemes in free field theory, where the formula is exact. The predictions of the approximation formula for several interacting models are well confirmed by Monte Carlo simulations. The following rule is found: For a critical model with fundametal Hamiltonian Η(φ), absence of critical slowing down can only be expected if the expansion of (Η(φ+ψ)) in terms of the shift ψ contains no relevant (mass) term. We also introduce a multigrid update procedure for nonabelian lattice gauge theory and study the acceptance rates for gauge group SU(2) in four dimensions. (orig.)

    Sequential Monte Carlo (SMC), or particle filtering, is a popular class of methods for sampling from an intractable target distribution using a sequence of simpler intermediate distributions. Like other importance sampling-based methods, performance is critically dependent on the proposal distribution: a bad proposal can lead to arbitrarily inaccurate estimates of the target distribution. This paper presents a new method for automatically adapting the proposal using an approximation of the Ku...

    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).

    We unify slice sampling and Hamiltonian Monte Carlo (HMC) sampling by demonstrating their connection under the canonical transformation from Hamiltonian mechanics. This insight enables us to extend HMC and slice sampling to a broader family of samplers, called monomial Gamma samplers (MGS). We analyze theoretically the mixing performance of such samplers by proving that the MGS draws samples from a target distribution with zero-autocorrelation, in the limit of a single parameter.

    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.

  15. Identification of thermotectonics events by 40Ar/39Ar methodology, in Jauru, Pontes e Lacerda and Rio Alegre Terrane - southwest portion of Amazon Craton

    International Nuclear Information System (INIS)

    The southwest portion of Amazon Craton, subject of these work, correspond to the southwest region of Mato Grosso State and is inserted on Rio Negro-Juruena, Rondoniana-San Ignacio and Sunsas-Aguapei geochronologic Provinces. This region is surrounded by three big terranes: Jauru, Pontes e Lacerda and Rio Alegre. The main aim of this study is to use the ages of termochronologic events obtained by 40Ar/39Ar methodology, including data of literature, to contribute with the study of the geotectonic evolution on this region. Twenty samples were analyzed and 40Ar/39Ar ages found for the Jauru Terrane vary of 1539 ± 3 Ma to 1338 ± 3 Ma, for the Pontes e Lacerda Terrane the interval obtained was of 946,1 ± 0,8 Ma to 890 ± 2 Ma and for Rio Alegre Terrane the ages are between 1407 ± 3 Ma to 1321 ± 2 Ma. U/Pb, Rb/Sr and Sm/Nd data from previous works, together with 40Ar/39Ar results allowed to obtain cooling average rates to each terrane. The Jauru Terrane units cooling age is equivalent to 1,52 Ga. The cooling average rates found to Alto Jauru Greenstone belt rocks is 2,4 deg C - 1,0 Ma and to Magmatic Arc Cachoeirinha is 10,8 deg C - 1,0 Ma. Stabilization age obtained for Pontes and Lacerda Terrane is about 900 Ma coherent with the cooling age of the Sunsas Aguapei Event (1,0 - 0,9 Ga) and cooling average rates calculate were the lower, equivalent to 1,0 deg C - 1,0 Ma. Cooling age found in Rio Alegre Terrane was 1,35 Ga, possibility correspond to collision age these terrane with Amazonian protoCraton and cooling average rates of 5,0 deg C - 1,0 Ma. Finally, younger age found of 900 Ma, coherent to the Sunsas - Aguapei Event, probably represent the last regional event that affected these rocks, characterizing the stabilization period of the southwest portion of Amazon Craton.

    2013-01-01

    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...

  17. Monte Carlo primer for health physicists

    International Nuclear Information System (INIS)

    The basic ideas and principles of Monte Carlo calculations are presented in the form of a primer for health physicists. A simple integral with a known answer is evaluated by two different Monte Carlo approaches. Random number, which underlie Monte Carlo work, are discussed, and a sample table of random numbers generated by a hand calculator is presented. Monte Carlo calculations of dose and linear energy transfer (LET) from 100-keV neutrons incident on a tissue slab are discussed. The random-number table is used in a hand calculation of the initial sequence of events for a 100-keV neutron entering the slab. Some pitfalls in Monte Carlo work are described. While this primer addresses mainly the bare bones of Monte Carlo, a final section briefly describes some of the more sophisticated techniques used in practice to reduce variance and computing time

    We present a new hybrid Monte Carlo method for 1-D equilibrium diffusion problems in which the radiation field coexists with matter in local thermodynamic equilibrium. This method, the Equilibrium Discrete Diffusion Monte Carlo (EqDDMC) method, combines Monte Carlo particles with spatially discrete diffusion solutions. We verify the EqDDMC method with computational results from three slab problems. The EqDDMC method represents an incremental step toward applying this hybrid methodology to non-equilibrium diffusion, where it could be simultaneously coupled to Monte Carlo transport.

    Full Text Available This article discusses the relation between the radio and the city from the analysis of the project Porto Alegre: sonorous landscapes, developed between 2005 and 2007 by the Journalism students from the Faculty of Biblioteconomy and Communication of UFRGS. The series of documentaries and sound stories proposed other systems of references to the perception and imagination of the city beyond the word and the voice, partly subverting what is usually called the urban space in radio. The pedagogical experience, on the one hand, interprets the urban space by the means of a gathering and assembling of its sounds; on the other hand, it discusses the limitations and the possibilities of radio journalism in the accomplishment of this initiative.

    Stochastic Approximation Monte Carlo (SAMC) has been established as a mathematically founded powerful flat-histogram Monte Carlo method, used to determine the density of states, g(E), of a model system. We show here how it can be generalized for the determination of multidimensional probability distributions (or equivalently densities of states) of macroscopic or mesoscopic variables defined on the space of microstates of a statistical mechanical system. This establishes this method as a systematic way for coarse graining a model system, or, in other words, for performing a renormalization group step on a model. We discuss the formulation of the Kadanoff block spin transformation and the coarse-graining procedure for polymer models in this language. We also apply it to a standard case in the literature of two-dimensional densities of states, where two competing energetic effects are present g(E_{1},E_{2}). We show when and why care has to be exercised when obtaining the microcanonical density of states g(E_{1}+E_{2}) from g(E_{1},E_{2}). PMID:27415383

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, therewas no significant relation between social sanitary conditions and the presence of oral diseases.

    abstinencia - que pueden ser confundidos con los síntomas de los trastornos de base - en pacientes psiquiátricos internados.Based on anecdotal clinical reports about the high prevalence of tobacco dependence in psychiatric inpatients, the Psychiatric Services of Hospital de Clinicas of Porto Alegre requested a study to ascertain its prevalence. Three consecutive censuses were developed, each 30 days apart, with a total of 103 in-patients, utilizing the Fagerström questionnaire for tobacco dependence to ascertain the severity of nicotine dependence. The prevalences found were 46.7% , 54.3 % and 38.9% , respectively, in the three consecutive samples (p>0.05. Dependence was categorized as severe in approximately 50% of all smokers in the three censuses. The high prevalence of nicotine dependence and the highest severity of dependence among the psychiatric patients confirms literature data and justifies interventions aimed at minimizing withdrawal symptoms - which may be confounded with symptoms of the psychiatric primary diagnosis - in patients hospitalized for psychiatric disorders.

    Full Text Available O condrossarcoma é uma neoplasia maligna proveniente de tecido cartilaginoso, cuja incidência em região de cabeça e pescoço é rara. É mais freqüente em pacientes do sexo masculino, entre a terceira e quarta décadas, e na face localiza-se no seio e osso maxilar, sendo raro no septo nasal. Esse relato descreve o caso de uma paciente do sexo feminino, de 13 anos de idade, que apresentava queixa de deformidade facial em região malar direita acompanhada de dores esporádicas. Ao exame físico apresentava um abaulamento de aproximadamente 3 cm de diâmetro em região malar esquerda, não sendo notada nenhuma alteração à rinoscopia anterior. Foram realizadas tomografia computadorizada (TC de seios paranasais, ressonância magnética de face e biópsia da lesão para estudo anatomopatológico, que inicialmente sugeria o diagnóstico de condroma. Após a exérese da massa, a paciente evoluiu com recidiva da lesão em apenas 5 meses. Diante deste fato surpreendente, foi requisitada a revisão da lâmina que evidenciou Condrossarcoma tipo I. Nova cirurgia foi realizada, visando a remoção do tumor, com tratamento radioterápico complementar. Atualmente, a paciente se encontra em acompanhamento ambulatorial, sem queixas álgicas e sem sinas de recidiva. Os condrossarcomas são tumores malignos de crescimento lento, mas localmente agressivos, tendo grande propensão a recidivas. A conduta é preferencialmente cirúrgica, uma vez que são pouco radiossensíveis e a quimioterapia é meramente paliativa. O objetivo deste estudo é apresentar um caso de condrossarcoma em seio maxilar, etmóide, esfenóide e septo, discutindo o quadro clínico, diagnóstico, fatores prognósticos e conduta.

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. Se indicó tratamiento quirúrgico en 96 (63.1% de los casos, fundamentalmente por insuficiencia cardíaca en 66. La mortalidad hospitalaria global fue 46 (30.2%. El desarrollo de complicaciones en la internación, la indicación de cirugía y la presencia de insuficiencia cardíaca refractaria al tratamiento fueron predictores independientes de mortalidad hospitalaria, mientras que la presencia de vegetaciones resultó un predictor independiente de mejor supervivencia. La identificación temprana de estos predictores descriptos podría ayudar a mejorar los resultados.

  14. Monte Carlo lattice program KIM

    International Nuclear Information System (INIS)

    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

  15. General Monte Carlo code MONK

    International Nuclear Information System (INIS)

    The Monte Carlo code MONK is a general program written to provide a high degree of flexibility to the user. MONK is distinguished by its detailed representation of nuclear data in point form i.e., the cross-section is tabulated at specific energies instead of the more usual group representation. The nuclear data are unadjusted in the point form but recently the code has been modified to accept adjusted group data as used in fast and thermal reactor applications. The various geometrical handling capabilities and importance sampling techniques are described. In addition to the nuclear data aspects, the following features are also described; geometrical handling routines, tracking cycles, neutron source and output facilities. 12 references. (U.S.)

    These are slides from a presentation for Parallel Summer School at Los Alamos National Laboratory. Solving discretized partial differential equations (PDEs) of interest can require a large number of computations. We can identify concurrency to allow parallel solution of discrete PDEs. Simulated particles histories can be used to solve the Boltzmann transport equation. Particle histories are independent in neutral particle transport, making them amenable to parallel computation. Physical parameters and method type determine the data dependencies of particle histories. Data requirements shape parallel algorithms for Monte Carlo. Then, Parallel Computational Physics and Parallel Monte Carlo are discussed and, finally, the results are given. The mesh passing method greatly simplifies the IMC implementation and allows simple load-balancing. Using MPI windows and passive, one-sided RMA further simplifies the implementation by removing target synchronization. The author is very interested in implementations of PGAS that may allow further optimization for one-sided, read-only memory access (e.g. Open SHMEM). The MPICH_RMA_OVER_DMAPP option and library is required to make one-sided messaging scale on Trinitite - Moonlight scales poorly. Interconnect specific libraries or functions are likely necessary to ensure performance. BRANSON has been used to directly compare the current standard method to a proposed method on idealized problems. The mesh passing algorithm performs well on problems that are designed to show the scalability of the particle passing method. BRANSON can now run load-imbalanced, dynamic problems. Potential avenues of improvement in the mesh passing algorithm will be implemented and explored. A suite of test problems that stress DD methods will elucidate a possible path forward for production codes.

    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.

    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.

    We present a scheme for the parallelization of quantum Monte Carlo on graphical processing units, focusing on bosonic systems and variational Monte Carlo. We use asynchronous execution schemes with shared memory persistence, and obtain an excellent acceleration. Comparing with single core execution, GPU-accelerated code runs over x100 faster. The CUDA code is provided along with the package that is necessary to execute variational Monte Carlo for a system representing liquid helium-4. The program was benchmarked on several models of Nvidia GPU, including Fermi GTX560 and M2090, and the latest Kepler architecture K20 GPU. Kepler-specific optimization is discussed.

    International Nuclear Information System (INIS)

    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

    The southwest portion of Amazon Craton, subject of these work, correspond to the southwest region of Mato Grosso State and is inserted on Rio Negro-Juruena, Rondoniana-San Ignacio and Sunsas-Aguapei geochronologic Provinces. This region is surrounded by three big terranes: Jauru, Pontes e Lacerda and Rio Alegre. The main aim of this study is to use the ages of termochronologic events obtained by {sup 40}Ar/{sup 39}Ar methodology, including data of literature, to contribute with the study of the geotectonic evolution on this region. Twenty samples were analyzed and {sup 40}Ar/{sup 39}Ar ages found for the Jauru Terrane vary of 1539 {+-} 3 Ma to 1338 {+-} 3 Ma, for the Pontes e Lacerda Terrane the interval obtained was of 946,1 {+-} 0,8 Ma to 890 {+-} 2 Ma and for Rio Alegre Terrane the ages are between 1407 {+-} 3 Ma to 1321 {+-} 2 Ma. U/Pb, Rb/Sr and Sm/Nd data from previous works, together with {sup 40}Ar/{sup 39}Ar results allowed to obtain cooling average rates to each terrane. The Jauru Terrane units cooling age is equivalent to 1,52 Ga. The cooling average rates found to Alto Jauru Greenstone belt rocks is 2,4 deg C - 1,0 Ma and to Magmatic Arc Cachoeirinha is 10,8 deg C - 1,0 Ma. Stabilization age obtained for Pontes and Lacerda Terrane is about 900 Ma coherent with the cooling age of the Sunsas Aguapei Event (1,0 - 0,9 Ga) and cooling average rates calculate were the lower, equivalent to 1,0 deg C - 1,0 Ma. Cooling age found in Rio Alegre Terrane was 1,35 Ga, possibility correspond to collision age these terrane with Amazonian protoCraton and cooling average rates of 5,0 deg C - 1,0 Ma. Finally, younger age found of 900 Ma, coherent to the Sunsas - Aguapei Event, probably represent the last regional event that affected these rocks, characterizing the stabilization period of the southwest portion of Amazon Craton.

  16. Smart detectors for Monte Carlo radiative transfer

    CERN Document Server

    Baes, Maarten

    2008-01-01

    Many optimization techniques have been invented to reduce the noise that is inherent in Monte Carlo radiative transfer simulations. As the typical detectors used in Monte Carlo simulations do not take into account all the information contained in the impacting photon packages, there is still room to optimize this detection process and the corresponding estimate of the surface brightness distributions. We want to investigate how all the information contained in the distribution of impacting photon packages can be optimally used to decrease the noise in the surface brightness distributions and hence to increase the efficiency of Monte Carlo radiative transfer simulations. We demonstrate that the estimate of the surface brightness distribution in a Monte Carlo radiative transfer simulation is similar to the estimate of the density distribution in an SPH simulation. Based on this similarity, a recipe is constructed for smart detectors that take full advantage of the exact location of the impact of the photon pack...

The scope of this paper is to analyze differences in alcohol and drug consumption, as well as on behavior associated with traffic accidents among men and women. A cross-sectional study was conducted with 609 sequential traffic accident victims attended in emergency care from Porto Alegre. Subjects gave a structured interview, were breathalyzed and had a saliva test for alcohol/drug screening. Results showed that women were mainly passengers or pedestrians (p < 0.001. There was no significant difference in positive blood alcohol concentration. However, men reported more binge drinking and THC use, while women had more benzodiazepine in their saliva (p<0.05. This is the first Brazilian study to compare alcohol and drug use among men and women who were the victims of traffic accidents. Results point to differences in the pattern of substance abuse, as well on risk behavior. Data may be useful for specific prevention strategies that take gender differences into consideration.

    This article aims to determine the pattern of alcohol use in the elderly and its associations with sociodemographic characteristics in an elderly sample of patients from the city of Porto Alegre, Rio Grande do Sul, Brazil. A cross-sectional study was conducted involving 557 seniors, aged 60 years or more, through application of the Mini International Neuropsychiatric Interview and a global assessment questionnaire for the elderly. The majority of the 557 senior citizens did not complete elementary school (58.3%), were white (65.1%), married (37.6%), had no caregiver (62.2%), were catholic (65.5%) and practicing their religion (68.6%), were retired (67.7%), and had a personal income of up to one minimum salary (56.1%). The study revealed 67 (12%) elderly people with a history of alcoholism, of which 17 (3.1%) had a diagnosis of current alcoholism, 50 (9%) had a history of alcohol dependence in the past and 16 (2.9%) had a current alcohol abuse problem. Men had a prevalence ratio of 11.6 times for a history of alcoholism in comparison to women. The results confirm that alcoholism is frequent in the population of Brazilian elderly, drawing attention to some socio-demographic characteristics that can make a difference in the early diagnosis of alcoholism.

    A cross-sectional, population-based study was conducted on a random sample of 427 elderly individuals living in Porto Alegre, Brazil, to establish the nutrient consumption profile and verify its association with sociodemographic and health variables. Dietary intake was assessed using the 24-hour Food Recall Survey and the Dietetic Research Investigation technique. Seventy percent of the elderly respondents were women: 48.5% were between 60 and 69 years old; 68.8% had less than 8 years of schooling; 39% had a family income of between 2 and 5 minimum wages and 58.4% took no physical exercise. Hypertension was the most prevalent disease among the elderly and 54.9% were underweight. Men consumed more calories, protein, fiber, minerals and vitamins than women. Carbohydrate and calcium intake increases with advancing age, while zinc intake decreases. Physical exercise increased the intake of calories, magnesium, potassium and phosphorus. The higher the schooling the greater the intake of vitamins B6 and B12; the higher the family income, the greater the consumption of vitamin B6 and folic acid. The results show that there are nutritional deficiencies in the daily diet of the Brazilian elderly population, especially among women and individuals over 80 years of age. PMID:26691795

The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and triatomines. Methods Techniques including the spool-and-line method and active searching (transects were used to identify natural foci. Results The food source for each triatomine was determined using the precipitin test, and the infection of marsupials was determined by xenodiagnosis. A total of 33 adults (domestic environment and 27 nymphs (wild environment of P. megistus were found in addition to 43 Didelphis albiventris specimens. The infection rates of triatomine adults, triatomine nymphs and opossums with T. cruzi I were 64%, 73% and 69%, respectively. Birds, rodents and opossums were the main resources used by triatomine. Conclusions This work presents the first characterization of a natural focus of P. megistus in Rio Grande do Sul. The natural characteristics of this focus and its implication in the transmission of T. cruzi are discussed.

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.

    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

    Full Text Available Abstract This article aims to determine the pattern of alcohol use in the elderly and its associations with sociodemographic characteristics in an elderly sample of patients from the city of Porto Alegre, Rio Grande do Sul, Brazil. A cross-sectional study was conducted involving 557 seniors, aged 60 years or more, through application of the Mini International Neuropsychiatric Interview and a global assessment questionnaire for the elderly. The majority of the 557 senior citizens did not complete elementary school (58.3%, were white (65.1%, married (37.6%, had no caregiver (62.2%, were catholic (65.5% and practicing their religion (68.6%, were retired (67.7%, and had a personal income of up to one minimum salary (56.1%. The study revealed 67 (12% elderly people with a history of alcoholism, of which 17 (3.1% had a diagnosis of current alcoholism, 50 (9% had a history of alcohol dependence in the past and 16 (2.9% had a current alcohol abuse problem. Men had a prevalence ratio of 11.6 times for a history of alcoholism in comparison to women. The results confirm that alcoholism is frequent in the population of Brazilian elderly, drawing attention to some socio-demographic characteristics that can make a difference in the early diagnosis of alcoholism.

    Full Text Available La escafocefalia constituye la manifestación más frecuente en el grupo de anomalías óseas denominadas craneostenosis, condición patológica que involucra el cierre prematuro de las suturas en el cráneo. La escafocefalia consiste en la obliteración temprana de la sutura sagital, limitando por lo tanto el desarrollo en dirección transversa del cráneo. El presente trabajo da cuenta de la manifestación de esta patología congénita en dos casos correspondientes a individuos de poblaciones aborígenes prehispánicas de Argentina. El primero de ellos procede de un sitio arqueológico del Período Tardío localizado en la cuenca del río Dulce en la provincia de Santiago del Estero. Caracteriza el sitio la presencia de numerosos montículos y alfarería del complejo Sunchituyoj. Los restos corresponden a un individuo adulto con atributos morfológicos masculinos. El calvarium se caracteriza por su extrema longitud y estrechez, constituyendo un típico caso de escafocefalia al no observarse rastro alguno de la sutura sagital, la que presenta fusión completa interna y externamente. El segundo caso, un individuo juvenil de sexo indeterminado, pertenece también a la provincia de Santiago del Estero, si bien su procedencia corresponde en este caso a la cuenca del río Salado. De la misma manera que el caso anterior, el cráneo presenta una longitud marcada en sentido ánteroposterior y un índice cefálico inferior a 70. La sutura sagital presenta fusión completa endocranealmente, en tanto que la sinostosis ectocraneal es parcial al apreciarse rastros de la sutura en la región bregmática.

    Monte Carlo neutron transport calculation has been used to obtain a reference solution in reactor physics analysis. The typical and widely-used Monte Carlo transport code is MCNP (Monte Carlo N-Particle Transport Code) developed in Los Alamos National Laboratory. The drawbacks of Monte-Carlo transport codes are the lacks of the capacities for the depletion and temperature dependent calculations. In this research we developed MCDEP (Monte Carlo Depletion Code Package) using MCNP with the capacity of the depletion calculation. This code package is the integration of MCNP and depletion module of ORIGEN-2 using the matrix exponential method. This code package enables the automatic MCNP and depletion calculations only with the initial MCNP and MCDEP inputs prepared by users. Depletion chains were simplified for the efficiency of computing time and the treatment of short-lived nuclides without cross section data. The results of MCDEP showed that the reactivity and pin power distributions for the PWR fuel pins and assemblies are consistent with those of CASMO-3 and HELIOS.

  1. Approaching Chemical Accuracy with Quantum Monte Carlo

    2012-01-01

    A quantum Monte Carlo study of the atomization energies for the G2 set of molecules is presented. Basis size dependence of diffusion Monte Carlo atomization energies is studied with a single determinant Slater-Jastrow trial wavefunction formed from Hartree-Fock orbitals. With the largest basis set, the mean absolute deviation from experimental atomization energies for the G2 set is 3.0 kcal/mol. Optimizing the orbitals within variational Monte Carlo improves the agreement between diffusion Monte Carlo and experiment, reducing the mean absolute deviation to 2.1 kcal/mol. Moving beyond a single determinant Slater-Jastrow trial wavefunction, diffusion Monte Carlo with a small complete active space Slater-Jastrow trial wavefunction results in near chemical accuracy. In this case, the mean absolute deviation from experimental atomization energies is 1.2 kcal/mol. It is shown from calculations on systems containing phosphorus that the accuracy can be further improved by employing a larger active space.

    We investigate the inclusion of variable spins in electronic structure quantum Monte Carlo, with a focus on diffusion Monte Carlo with Hamiltonians that include spin-orbit interactions. Following our previous introduction of fixed-phase spin-orbit diffusion Monte Carlo (FPSODMC), we thoroughly discuss the details of the method and elaborate upon its technicalities. We present a proof for an upper-bound property for complex nonlocal operators, which allows for the implementation of T-moves to ensure the variational property. We discuss the time step biases associated with our particular choice of spin representation. Applications of the method are also presented for atomic and molecular systems. We calculate the binding energies and geometry of the PbH and Sn$_2$ molecules, as well as the electron affinities of the 6$p$ row elements in close agreement with experiments.

    We present the public release of the Bayesian sampling algorithm for cosmology, CosmoPMC (Cosmology Population Monte Carlo). CosmoPMC explores the parameter space of various cosmological probes, and also provides a robust estimate of the Bayesian evidence. CosmoPMC is based on an adaptive importance sampling method called Population Monte Carlo (PMC). Various cosmology likelihood modules are implemented, and new modules can be added easily. The importance-sampling algorithm is written in C, and fully parallelised using the Message Passing Interface (MPI). Due to very little overhead, the wall-clock time required for sampling scales approximately with the number of CPUs. The CosmoPMC package contains post-processing and plotting programs, and in addition a Monte-Carlo Markov chain (MCMC) algorithm. The sampling engine is implemented in the library pmclib, and can be used independently. The software is available for download at http://www.cosmopmc.info.

  10. SPQR: a Monte Carlo reactor kinetics code

    International Nuclear Information System (INIS)

    The SPQR Monte Carlo code has been developed to analyze fast reactor core accident problems where conventional methods are considered inadequate. The code is based on the adiabatic approximation of the quasi-static method. This initial version contains no automatic material motion or feedback. An existing Monte Carlo code is used to calculate the shape functions and the integral quantities needed in the kinetics module. Several sample problems have been devised and analyzed. Due to the large statistical uncertainty associated with the calculation of reactivity in accident simulations, the results, especially at later times, differ greatly from deterministic methods. It was also found that in large uncoupled systems, the Monte Carlo method has difficulty in handling asymmetric perturbations

    Markov chain Monte Carlo methods explicitly defined on the manifold of probability distributions have recently been established. These methods are constructed from diffusions across the manifold and the solution of the equations describing geodesic flows in the Hamilton-Jacobi representation. This paper takes the differential geometric basis of Markov chain Monte Carlo further by considering methods to simulate from probability distributions that themselves are defined on a manifold, with common examples being classes of distributions describing directional statistics. Proposal mechanisms are developed based on the geodesic flows over the manifolds of support for the distributions, and illustrative examples are provided for the hypersphere and Stiefel manifold of orthonormal matrices.

    A method which combines the accuracy of Monte Carlo dose calculation with a finite size pencil-beam based intensity modulation optimization is presented. The pencil-beam algorithm is employed to compute the fluence element updates for a converging sequence of Monte Carlo dose distributions. The combination is shown to improve results over the pencil-beam based optimization in a lung tumour case and a head and neck case. Inhomogeneity effects like a broader penumbra and dose build-up regions can be compensated for by intensity modulation.

    An overview of recent work on Monte Carlo simulations of a granular binary mixture is presented. The results are obtained numerically solving the Enskog equation for inelastic hard-spheres by means of an extension of the well-known direct Monte Carlo simulation (DSMC) method. The homogeneous cooling state and the stationary state reached using the Gaussian thermostat are considered. The temperature ratio, the fourth velocity moments and the velocity distribution functions are obtained for both cases. The shear viscosity characterizing the momentum transport in the thermostatted case is calculated as well. The simulation results are compared with analytical predictions showing an excellent agreement.

    Monte Carlo simulations are a valuable tool to model the generation, separation, and collection of charges in organic photovoltaics where charges move by hopping in a complex nanostructure and Coulomb interactions between charge carriers are important. We review the Monte Carlo techniques that have been applied to this problem, and describe the results of simulations of the various recombination processes that limit device performance. We show how these processes are influenced by the local physical and energetic structure of the material, providing information that is useful for design of efficient photovoltaic systems.

    Full Text Available The Bipolar Mood Disorder is characterized by the alternation of depressive crises with episodes of mania or euphoria, having these patients 15 to 35 times more chances of suicide, as compared with people without this disorder. The pharmacotherapy is fundamental for this disease, aiming to decrease the frequency of episodes and disease severity. In these patients, the polypharmacy has recently increased and one of the main difficulties is the adherence to treatment. The objective of this study was to contribute for the improvement of bipolar patients health conditions, developing their respective pharmacotherapeutic follow-up. Twenty eight adult bipolar patients who were participants of a specialized clinic within a tertiary hospital in Porto Alegre have been randomly selected, and the Dader Method of pharmacotherapeutic follow-up has been applied. The more common clinical comorbidities were: hypertension (50%, obesity (46.43%, and hypothyroidism (36.29%. The bipolar patients are more susceptible to clinical comorbidities, and many of them could be due to pharmacotherapy. Only 1.43% of patients presented Drug Related Problems, being all of them resolved along the study. It was also observed that 32.14% of evaluated patients presented low adherence to treatment, and between these patients, 55.56% passed to have good adherence after pharmacotherapeutic follow-up. The pharmacotherapeutic follow-up is fundamental for the improvement of patient's health. New studies, with higher number of patients and longer duration, are necessary to evaluate the percentage of patients that could be beneficiary of Pharmaceutical Care.O Transtorno do Humor Bipolar é caracterizando pela alternância de crises depressivas com episódios de mania ou euforia, tendo estes pacientes 15-35 vezes mais chances de suicídio em comparação com pessoas sem este transtorno.

    The purpose of this study is to assess the composition of wet precipitation in three sites of the metropolitan area of Porto Alegre. Besides the variables usually considered, such as pH, conductivity, major ions (Cl{sup -}, NO{sub 3}{sup -}, F{sup -}, SO{sub 4}{sup 2-}, Na{sup +}, K{sup +}, Mg{sup 2+}, NH{sub 4}{sup +} and Ca{sup 2+}) and metallic elements (Cd, Co, Cr, Cu, Fe, Mn and Ni), the suspended matter was examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM), with energy dispersive system (EDS), for better identification of possible anthropogenic material in this wet precipitation. Results showed an alkaline pH in the samples analyzed and higher concentrations for Na{sup +}, Cl{sup -} and SO{sub 4}{sup 2-}. The acidification and neutralization potential between anions (SO{sub 4}{sup 2-} + NO{sub 3}{sup -}) and cations (Ca{sup 2+} + Mg{sup 2+} + K{sup +} + NH{sub 4}{sup +}) showed a good correlation (0.922). The metallic elements with highest values were Zn, Fe and Mn. Results of XRD identified the presence of some minerals such as quartz, feldspar, mica, clay, carbonates and sulfates. In samples analyzed with SEM, we detected pyroxene, biotite, amphibole and oxides. Cluster analysis (CA) was applied to the data matrix to identify potential pollution sources of metals (natural or anthropogenic) and the association with minerals found in the analysis of SEM.

    Full Text Available Verificou-se a prevalência de indicadores emocionais negativos e fatores associados em 430 mães adolescentes de 14 a 16 anos de Porto Alegre, RS. Foram estudadas variáveis sociodemográficas, relações sociais e familiares, aspectos reprodutivos, abuso e violência. As razões de prevalência (RP foram obtidas por regressão de Poisson mediante análise hierarquizada. A prevalência de sofrimento psíquico intenso foi 32,6%, estando associado à baixa classe social, à não repetência escolar, ao relacionamento ruim com a mãe, à não aceitação da gestação pelo parceiro e à falta de apoio da família frente à gestação. A prevalência de autovalorização negativa foi 15,4%, permanecendo associada ao relacionamento ruim com a mãe e a não possuir uma pessoa confidente. Pouca ou nenhuma expectativa em relação ao futuro foi encontrada em 7,5% das adolescentes, estando associada à repetência escolar, à criação pela mãe biológica, à idade precoce da primeira relação sexual e à ocorrência de abuso físico. A alta prevalência de sofrimento psíquico, encontrada nas mães adolescentes, merece atenção especial das políticas públicas de saúde para a inclusão de profissionais habilitados ao manejo dos aspectos emocionais no atendimento da maternidade precoce.

    The Trad-MCN bioassay was used to investigate the genotoxicity on Tradescantia pallida var. purpurea plants exposed to variations in the environmental conditions in urban and rural sites in the metropolitan area of Porto Alegre, southern Brazil, over a one-year period. In spring 2009 and in summer, autumn and winter 2010, potted plants of T. pallida var. purpurea were exposed at two sites with different characteristics: the urban area of the municipality of Estância Velha, with leather and footwear industrial activity, and a Site of Special Environmental Interest in the rural area of the municipality of Novo Hamburgo. Other plants comprised the control group and were kept indoors. Frequencies of micronuclei (MCN) were determined in early tetrads of pollen mother cells and expressed as MCN/100 tetrads. Climate data were also registered during the experiment. MCN frequencies in the urban area were significantly higher (up to 8.13) than those found in the rural area (up to 1.26) and in the control group (up to 1.10), which did not differ statistically from each other over the year. The higher MCN frequencies observed in the urban site can be attributed to air pollution, but also may have been influenced by microclimatic and daily thermal variation differences between sites. Higher temperatures recorded in spring and summer may have influenced MCN frequencies observed in the urban site. No clear relation was observed between rainfall and MCN frequencies. Similar and high relative humidity percentages were registered over the period of the study. Considering that the bioindicator plant presents an integrated response to abiotic factors such as pollutants and weather conditions, it can be used as an additional tool that can point to synergistic effects of environmental variables on organisms.

    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.

  9. On the use of stochastic approximation Monte Carlo for Monte Carlo integration

    KAUST Repository

    Liang, Faming

    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.

    Full Text Available Esse artigo trata dos grupos como modalidade assistencial utilizada pelos serviços de atenção básica de saúde. Oficinas, grupos de educação em saúde e palestras constituem atividades diferenciadas em relação aos demais atendimentos tradicionais. O estudo que subsidia essa discussão teve como objetivo conhecer o perfil da assistência, sob a forma de grupos, prestada nas unidades que compõem a rede básica de saúde de Porto Alegre. Foram abordados 116 profissionais, de um total de 124 serviços de saúde, entre os quais 96 desenvolviam grupos. Evidenciou-se que os mesmos têm relevância terapêutica por favorecerem a troca de informações e o aprendizado sobre aspectos relacionados à saúde/doença. Constituem práticas inclusivas, capazes de vincular os usuários aos serviços e de reformular o modelo assistencial vigente. Assim, constatou-se que a compreensão dessas práticas remete a sua dimensão de qualificação da assistência coletiva e também a uma dimensão estratégica de compensação de atendimento às crescentes demandas de saúde.This article deals with groups as an assistential modality used by the services of basic health attention. Workshops, health education groups, as well as, lectures are different activities done in relation to other traditional attendances. The study that is behind this discussion had as its main aim to know the profile of assistance, under groups' organization, offered in the Units which make part of the Basic Health Network in Porto Alegre. Within a total of 124 health services, 116 professionals were approached, among them, 96 developed groups. We could verify that the groups have therapeutic relevance because they favor the sharing of information and the learning about aspects which are related to the topic health-sickness. They constitute inclusive practices, which are able to create a link with the users and the service, as well as, to reformulate the existing assistential model

    Full Text Available Este artigo investiga o quanto o tamanho relativo da população juvenil na Região Metropolitana de Porto Alegre (RMPA afetou a ocupação e o desemprego desse segmento no período 1993-2004. Esta questão ganha relevância no presente tanto pelo fato de que diversos estudos têm apontado a ocorrência do fenômeno de uma onda jovem nas principais regiões metropolitanas do país, nos anos 90, quanto pela correlata observação de uma tendência à elevação do desemprego entre os jovens no período. Assim, primeiramente, é feita uma síntese dos argumentos a respeito dos efeitos do tamanho relativo da coorte juvenil sobre a situação deste grupo populacional no mercado de trabalho. Em seguida, identificam-se as principais tendências da população e da força de trabalho juvenil no mercado de trabalho da RMPA, bem como se estimam os efeitos do tamanho relativo da coorte juvenil sobre a ocupação e o desemprego desse grupo populacional.This article studies to what extent the relative size of the young population in the Metropolitan Area of Porto Alegre (RMPA affected employment and unemployment of this group between 1993 and 2004. This question has taken on considerable importance, based on two different factors. The first is the fact that a number of studies have indicated the occurrence of the phenomenon of a wave of youth in the largest metropolitan areas in the country during the 1990s. Secondly, the concomitant trend toward higher unemployment among youth during this same period. The article is organized in the following way: after the Introduction, Section 2 presents a synthesis of the arguments regarding the effects of the relative size of the cohort of youth on the situation of this group in the labor market. Section 3 identifies the main trends of the younger population within the labor market in the RMPA and estimates the effects of the relative size of this cohort on the employment and unemployment of this population group

    Full Text Available Los leiomiomas perianales son tumoraciones derivadas de células mesenquimales distribuidas por todo el cuerpo. Histológicamente se han clasificado en tres subtipos: vascular, no vascular y epiteloide. El subtipo vascular puede ser sólido, cavernoso o venoso. Los leiomiomas son raros en adultos, con incidencia de 0,1 %, generalmente se presentan entre la cuarta a sexta década de la vida con predominio en mujeres en caso de ser benignos. La forma de presentación más frecuente es un nódulo palpable, próximo al ano e indoloro. El diagnóstico se realiza según criterios histológicos e inmunohistoquímicos, además son útiles la ecografía endoanal y RMN. La exéresis es la primera opción terapéutica. Se presenta caso de paciente femenino de 41 años de edad, quien consulta por presentar nódulo palpable perianal derecho, con dolor a la palpación, de ocho meses de evolución, con valores normales de marcadores tumorales, el ultrasonido revela a nivel perianal derecho imagen sólida, hipocrómica (con tejido lineal fibroso, mide 4.82x 6.7x 6.87cm, la RMN muestra lesión ocupante de espacio en la misma ubicación, Doppler Color sin vascularización.

    Full Text Available Num estudo retrospectivo de 1.071 necropsias de bovinos, foram encontrados 20 casos de babesiose cerebral confirmados pelo exame de esfregaços do córtex telencefálico. A maioria desses casos ocorreu no verão, em bovinos adultos de raças européias ou suas cruzas. Além dos sinais clínicos neurológicos, observou-se hemoglobinúria, anorexia, febre, taquicardia, taquipnéia e queda na produção de leite. O hemograma realizado em cinco bovinos afetados revelou acentuada anemia regenerativa; em média, 20% dos eritrócitos estavam parasitados por Babesia bovis. Na necropsia de todos os casos, a substância cinzenta dos córtices telencefálico e cerebelar e dos núcleos da base era consistente e caracteristicamente róseo-cereja. Essa coloração devia-se ao seqüestro de eritrócitos nos capilares encefálicos. Nesses eritrócitos, podiam-se observar, tanto em esfregaços do córtex como em preparações histológicas do encéfalo, microorganismos com morfologia compatível com B. bovis. Outros achados de necropsia incluíam hemoglobinúria, rins vermelho-escuros, hepatoesplenomegalia, fígado vermelho-alaranjado, icterícia, hemorragias epicárdicas e endocárdicas e edema e congestão dos linfonodos mesentéricos.

    Full Text Available Por meio de técnicas de análise espacial foram estimados os diferenciais intra-urbanos da prevalência de HIV entre gestantes no município de Porto Alegre, Rio Grande do Sul. As estimativas foram obtidas por meio da suavização espacial dos pontos referentes às residências de nascidos vivos e gestantes HIV positivas para o ano de 2003. Foi identificada a sobreposição de áreas de alta prevalência com favelas da cidade, o que ratifica o processo de pauperização da Aids e aponta locais onde estratégias de atenção primária e educação devem ser reforçadas.Spatial analysis techniques were used to estimate the interurban differential HIV prevalence among pregnant women in the city of Porto Alegre, Southern Brazil. The estimates were produced through the spatial smoothing of residence pinpoints with live newborns and HIV infected pregnant women for the year of 2003. The overlay of high prevalence areas in city slums was identified. This finding confirms the intensification of AIDS epidemic among poor urban populations, and indicates areas where basic care and educational strategies should be reinforced.

    Full Text Available Abstract Background Breast cancer (BC is a major public health problem, with rising incidence in many regions of the globe. Although mortality has recently dropped in developed countries, death rates are still increasing in some developing countries, as seen in Brazil. Among the reasons for this phenomenon are the lack of structured screening programs, a long waiting period between diagnosis and treatment, and lack of access to health services for a large proportion of the Brazilian population. Methods and design Since 2004, an intervention study in a cohort of women in Southern Brazil, denominated Porto Alegre Breast Health Intervention Cohort, is being conducted in order to test the effectiveness and cost-effectiveness of a model for BC early detection and treatment. In this study, over 4,000 women from underserved communities aged 40 to 69 years are being screened annually with mammography and clinical breast examination performed by a multidisciplinary team, which also involves nutritional counseling and genetic cancer risk assessment. Risk factors for BC development are also being evaluated. Active search of participants by lay community health workers is one of the major features of our program. The accrual of new participants was concluded in 2006 and the study will last for 10 years. The main goal of the study is to demonstrate significant downstaging of BC in an underserved population through proper screening, attaining a higher rate of early-stage BC diagnoses than usually seen in women diagnosed in the Brazilian Public Health System. Preliminary results show a very high BC incidence in this population (117 cases per 100,000 women per year, despite a low prevalence of classical risk factors. Discussion This study will allow us to test a model of BC early diagnosis and treatment and evaluate its cost-effectiveness in a developing country where the mortality associated with this disease is very high. Also, it might contribute to the

    Full Text Available Se estudia un caso de seudología fantástica, trastorno de la personalidad incluido en los trastornos no especificados (DSM-III-R y que podría ser definido, siguiendo a CASTILLA DEL PINO, como una caracterosis impositiva del self intelectual. El síntoma fundamental, en el caso que comentamos, está constituido por la personalidad del paciente, que se cimenta en un un falso self -expresado éste en los numerosos engaños y mentiras que giran, principalmente, alrededor de su identidad intelectual-. Como consecuencia de estas conductas mendaces, el paciente manifiesta, además, conductas desadaptivas (alcoholismo, endeudamientos en cadena, etc. A diferencia del fantasioso, el seudólogo opta por la acción: su intención es imponer el self fantaseado a los demás, por lo que no le basta la simple fantasía si ésta no es llevada a la práctica. Asímismo, es preciso diferenciar el cuadro seudólogo de las neurosis histéricas, estados hipomaníacos y psicosis paranoides crónicas de exaltación intelectual. El abordaje psicoterapéutico suele verse dificultado por la actitud del paciente.

    Sreeja, K. K.; Ipsen, John H.; Kumar, P. B. Sunil

    2015-07-01

    Lipid vesicles are closed two dimensional fluid surfaces that are studied extensively as model systems for understanding the physical properties of biological membranes. Here we review the recent developments in the Monte Carlo techniques for simulating fluid vesicles and discuss some of their applications. The technique, which treats the membrane as an elastic sheet, is most suitable for the study of large scale conformations of membranes. The model can be used to study vesicles with fixed and varying topologies. Here we focus on the case of multi-component membranes with the local lipid and protein composition coupled to the membrane curvature leading to a variety of shapes. The phase diagram is more intriguing in the case of fluid vesicles having an in-plane orientational order that induce anisotropic directional curvatures. Methods to explore the steady state morphological structures due to active flux of materials have also been described in the context of Monte Carlo simulations.

  10. Hybrid Monte Carlo with Chaotic Mixing

    CERN Document Server

    Kadakia, Nirag

    2016-01-01

    We propose a hybrid Monte Carlo (HMC) technique applicable to high-dimensional multivariate normal distributions that effectively samples along chaotic trajectories. The method is predicated on the freedom of choice of the HMC momentum distribution, and due to its mixing properties, exhibits sample-to-sample autocorrelations that decay far faster than those in the traditional hybrid Monte Carlo algorithm. We test the methods on distributions of varying correlation structure, finding that the proposed technique produces superior covariance estimates, is less reliant on step-size tuning, and can even function with sparse or no momentum re-sampling. The method presented here is promising for more general distributions, such as those that arise in Bayesian learning of artificial neural networks and in the state and parameter estimation of dynamical systems.

    Monte Carlo simulation is an essential component of experimental particle physics in all the phases of its life-cycle: the investigation of the physics reach of detector concepts, the design of facilities and detectors, the development and optimization of data reconstruction software, the data analysis for the production of physics results. This note briefly outlines some research topics related to Monte Carlo simulation, that are relevant to future experimental perspectives in particle physics. The focus is on physics aspects: conceptual progress beyond current particle transport schemes, the incorporation of materials science knowledge relevant to novel detection technologies, functionality to model radiation damage, the capability for multi-scale simulation, quantitative validation and uncertainty quantification to determine the predictive power of simulation. The R&D on simulation for future detectors would profit from cooperation within various components of the particle physics community, and synerg...

    2008-01-01

    Because of properties of QED, the bremsstrahlung corrections to decays of particles or resonances can be calculated, with a good precision, separately from other effects. Thanks to the widespread use of event records such calculations can be embodied into a separate module of Monte Carlo simulation chains, as used in High Energy Experiments of today. The PHOTOS Monte Carlo program is used for this purpose since nearly 20 years now. In the following talk let us review the main ideas and constraints which shaped the program version of today and enabled it widespread use. Finally, we will underline importance of aspects related to reliability of program results: event record contents and implementation of channel specific matrix elements.

    Baes, Maarten; Lunttila, Tuomas; Bianchi, Simone; Camps, Peter; Juvela, Mika; Kuiper, Rolf

    2016-01-01

    Biasing or importance sampling is a powerful technique in Monte Carlo radiative transfer, and can be applied in different forms to increase the accuracy and efficiency of simulations. One of the drawbacks of the use of biasing is the potential introduction of large weight factors. We discuss a general strategy, composite biasing, to suppress the appearance of large weight factors. We use this composite biasing approach for two different problems faced by current state-of-the-art Monte Carlo radiative transfer codes: the generation of photon packages from multiple components, and the penetration of radiation through high optical depth barriers. In both cases, the implementation of the relevant algorithms is trivial and does not interfere with any other optimisation techniques. Through simple test models, we demonstrate the general applicability, accuracy and efficiency of the composite biasing approach. In particular, for the penetration of high optical depths, the gain in efficiency is spectacular for the spe...

  14. No-compromise reptation quantum Monte Carlo

    International Nuclear Information System (INIS)

    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)

  15. Monte Carlo Shell Model Mass Predictions

    International Nuclear Information System (INIS)

    The nuclear mass calculation is discussed in terms of large-scale shell model calculations. First, the development and limitations of the conventional shell model calculations are mentioned. In order to overcome the limitations, the Quantum Monte Carlo Diagonalization (QMCD) method has been proposed. The basic formulation and features of the QMCD method are presented as well as its application to the nuclear shell model, referred to as Monte Carlo Shell Model (MCSM). The MCSM provides us with a breakthrough in shell model calculations: the structure of low-lying states can be studied with realistic interactions for a nearly unlimited variety of nuclei. Thus, the MCSM can contribute significantly to the study of nuclear masses. An application to N∼20 unstable nuclei far from the β-stability line is mentioned

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.

  17. Multilevel Monte Carlo Approaches for Numerical Homogenization

    KAUST Repository

    Efendiev, Yalchin R.

    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.

  18. Status of Monte Carlo at Los Alamos

    International Nuclear Information System (INIS)

    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

  19. Monte Carlo study of real time dynamics

    Alexandru, Andrei; Bedaque, Paulo F; Vartak, Sohan; Warrington, Neill C

    2016-01-01

    Monte Carlo studies involving real time dynamics are severely restricted by the sign problem that emerges from highly oscillatory phase of the path integral. In this letter, we present a new method to compute real time quantities on the lattice using the Schwinger-Keldysh formalism via Monte Carlo simulations. The key idea is to deform the path integration domain to a complex manifold where the phase oscillations are mild and the sign problem is manageable. We use the previously introduced "contraction algorithm" to create a Markov chain on this alternative manifold. We substantiate our approach by analyzing the quantum mechanical anharmonic oscillator. Our results are in agreement with the exact ones obtained by diagonalization of the Hamiltonian. The method we introduce is generic and in principle applicable to quantum field theory albeit very slow. We discuss some possible improvements that should speed up the algorithm.

  1. The lund Monte Carlo for jet fragmentation

    International Nuclear Information System (INIS)

    We present a Monte Carlo program based on the Lund model for jet fragmentation. Quark, gluon, diquark and hadron jets are considered. Special emphasis is put on the fragmentation of colour singlet jet systems, for which energy, momentum and flavour are conserved explicitly. The model for decays of unstable particles, in particular the weak decay of heavy hadrons, is described. The central part of the paper is a detailed description on how to use the FORTRAN 77 program.

  2. Autocorrelations in hybrid Monte Carlo simulations

    International Nuclear Information System (INIS)

    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.)

    We propose a variant of the simulated annealing method for optimization in the multivariate analysis of differentiable functions. The method uses global actualizations via the hybrid Monte Carlo algorithm in their generalized version for the proposal of new configurations. We show how this choice can improve upon the performance of simulated annealing methods (mainly when the number of variables is large) by allowing a more effective searching scheme and a faster annealing schedule.

    Virtual photon scattering in e^+e^- collisions can result in events with the electron-positron pair at large rapidity separation with hadronic activity in between. The BFKL equation resums large logarithms that dominate the cross section for this process. We report here on a Monte Carlo method for solving the BFKL equation that allows kinematic constraints to be taken into account. The application to e^+e^- collisions is in progress.

An approximated value of 3.136 is obtained, corresponding to a 0.17% error on the exact value of {\\pi}. To our knowledge, this represents the first attempt at estimating {\\pi} using such method, thus opening up new perspectives towards computing mathematical constants using everyday tools.

    Petroleo Brasileiro S.A - PETROBRAS, through Espirito Santo Business Unit, has been intensifying the utilization of underwater on its onshore production activities, where the utilization of water or steam injection techniques on the reservoir rock become necessary, aiming at supplemental hydrocarbons recovery in the mature fields or heavy oil fields, such as Fazenda Alegre field. The hydrogeologic study of the groundwater potential appears as a tool capable to improve the planning and utilization of the hydro resources of the region. The main tool used was the geophysics investigation of electric resistivity technique able to investigate aquifers as deep as 200 m. The drilling of the first wells selected proves the expectations according to the groundwater potential resources of the area. The maximum rate water obtained before that was about 30 m{sup 3}/h. Considering deeper wells (180 m), which incorporate news aquifers, it practically doubles, achieving values in a set of 60 m{sup 3}/h. The characterization of these recent discoveries/aquifers is a sign of news horizons for the local society, especially concerning the possibility of giving support in agricultural projects and rural communities supply concomitant with the process of petroleum projects expected in Fazenda Alegre helping thus, the sustainable development in the areas surrounding the project.

  13. Quantum Monte Carlo for vibrating molecules

    International Nuclear Information System (INIS)

    Quantum Monte Carlo (QMC) has successfully computed the total electronic energies of atoms and molecules. The main goal of this work is to use correlation function quantum Monte Carlo (CFQMC) to compute the vibrational state energies of molecules given a potential energy surface (PES). In CFQMC, an ensemble of random walkers simulate the diffusion and branching processes of the imaginary-time time dependent Schroedinger equation in order to evaluate the matrix elements. The program QMCVIB was written to perform multi-state VMC and CFQMC calculations and employed for several calculations of the H2O and C3 vibrational states, using 7 PES's, 3 trial wavefunction forms, two methods of non-linear basis function parameter optimization, and on both serial and parallel computers. In order to construct accurate trial wavefunctions different wavefunctions forms were required for H2O and C3. In order to construct accurate trial wavefunctions for C3, the non-linear parameters were optimized with respect to the sum of the energies of several low-lying vibrational states. In order to stabilize the statistical error estimates for C3 the Monte Carlo data was collected into blocks. Accurate vibrational state energies were computed using both serial and parallel QMCVIB programs. Comparison of vibrational state energies computed from the three C3 PES's suggested that a non-linear equilibrium geometry PES is the most accurate and that discrete potential representations may be used to conveniently determine vibrational state energies

  14. Monte Carlo dose mapping on deforming anatomy

    Zhong, Hualiang; Siebers, Jeffrey V.

    2009-10-01

    This paper proposes a Monte Carlo-based energy and mass congruent mapping (EMCM) method to calculate the dose on deforming anatomy. Different from dose interpolation methods, EMCM separately maps each voxel's deposited energy and mass from a source image to a reference image with a displacement vector field (DVF) generated by deformable image registration (DIR). EMCM was compared with other dose mapping methods: energy-based dose interpolation (EBDI) and trilinear dose interpolation (TDI). These methods were implemented in EGSnrc/DOSXYZnrc, validated using a numerical deformable phantom and compared for clinical CT images. On the numerical phantom with an analytically invertible deformation map, EMCM mapped the dose exactly the same as its analytic solution, while EBDI and TDI had average dose errors of 2.5% and 6.0%. For a lung patient's IMRT treatment plan, EBDI and TDI differed from EMCM by 1.96% and 7.3% in the lung patient's entire dose region, respectively. As a 4D Monte Carlo dose calculation technique, EMCM is accurate and its speed is comparable to 3D Monte Carlo simulation. This method may serve as a valuable tool for accurate dose accumulation as well as for 4D dosimetry QA.

Its regional setting is seen in the wide angle color mosaic (Figure A). The Libya Montes were formed by the giant impact that created the ancient Isidis basin. The Libya Mountains and valleys--like the one shown here--were subsequently modified and eroded by other processes, including wind, impact cratering, and flow of liquid water to make the small valley that runs across the middle of the scene. Until the mission was canceled, the Libya Montes region was among the top two candidates for the Mars Surveyor 2001 Lander. This image, illuminated by sunlight from the left, covers an area 3 kilometers (1.9 miles) wide and 19 kilometers (11.8 miles) long. The scene is located near 1.5oN, 278.4oW and was acquired on June 27, 1999. The high resolution color view (top) was created by combining the colors derived from Mars Orbiter Camera Wide Angle views of the region obtained in May 1999 (Figures A and B) with the high resolution view obtained in June 1999 (Figure C).

    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.Este é um estudo quanti/qualitativo sobre homicídios entre adolescentes em Porto Alegre, tendo como base uma seriação histórica para a década de 90 e as histórias de vida e morte nesse grupo, particularizando o ano de 1997.

Admite-se, a partir disso, que as formas de morrer sofrem influência das culturas de gênero e os homicídios se sustentam em símbolos e posições de poder que caracterizam um tipo de masculinidade. Essa expressão de masculinidade na forma de violência mostra sua face também no domínio sobre o corpo feminino, observado nas situações de homicídio envolvendo as mulheres adolescentes.

    In a Monte Carlo criticality calculation, before the tallying of quantities can begin, a converged fission source (the fundamental eigenvector of the fission kernel) is required. Tallies of interest may include powers, absorption rates, leakage rates, or the multiplication factor (the fundamental eigenvalue of the fission kernel, k{sub eff}). Just as in the power iteration method of linear algebra, if the dominance ratio (the ratio of the first and zeroth eigenvalues) is high, many iterations of neutron history simulations are required to isolate the fundamental mode of the problem. Optically large systems have large dominance ratios, and systems containing poor neutron communication between regions are also slow to converge. The fission matrix method, implemented into MCNP[1], addresses these problems. When Monte Carlo random walk from a source is executed, the fission kernel is stochastically applied to the source. Random numbers are used for: distances to collision, reaction types, scattering physics, fission reactions, etc. This method is used because the fission kernel is a complex, 7-dimensional operator that is not explicitly known. Deterministic methods use approximations/discretization in energy, space, and direction to the kernel. Consequently, they are faster. Monte Carlo directly simulates the physics, which necessitates the use of random sampling. Because of this statistical noise, common convergence acceleration methods used in deterministic methods do not work. In the fission matrix method, we are using the random walk information not only to build the next-iteration fission source, but also a spatially-averaged fission kernel. Just like in deterministic methods, this involves approximation and discretization. The approximation is the tallying of the spatially-discretized fission kernel with an incorrect fission source. We address this by making the spatial mesh fine enough that this error is negligible. As a consequence of discretization we get a

    Quantum Monte Carlo (QMC) has successfully computed the total electronic energies of atoms and molecules. The main goal of this work is to use correlation function quantum Monte Carlo (CFQMC) to compute the vibrational state energies of molecules given a potential energy surface (PES). In CFQMC, an ensemble of random walkers simulate the diffusion and branching processes of the imaginary-time time dependent Schroedinger equation in order to evaluate the matrix elements. The program QMCVIB was written to perform multi-state VMC and CFQMC calculations and employed for several calculations of the H{sub 2}O and C{sub 3} vibrational states, using 7 PES`s, 3 trial wavefunction forms, two methods of non-linear basis function parameter optimization, and on both serial and parallel computers. In order to construct accurate trial wavefunctions different wavefunctions forms were required for H{sub 2}O and C{sub 3}. In order to construct accurate trial wavefunctions for C{sub 3}, the non-linear parameters were optimized with respect to the sum of the energies of several low-lying vibrational states. In order to stabilize the statistical error estimates for C{sub 3} the Monte Carlo data was collected into blocks. Accurate vibrational state energies were computed using both serial and parallel QMCVIB programs. Comparison of vibrational state energies computed from the three C{sub 3} PES`s suggested that a non-linear equilibrium geometry PES is the most accurate and that discrete potential representations may be used to conveniently determine vibrational state energies.

  18. A Monte Carlo approach to water management

    Science.gov (United States)

    Koutsoyiannis, D.

    2012-04-01

    Common methods for making optimal decisions in water management problems are insufficient. Linear programming methods are inappropriate because hydrosystems are nonlinear with respect to their dynamics, operation constraints and objectives. Dynamic programming methods are inappropriate because water management problems cannot be divided into sequential stages. Also, these deterministic methods cannot properly deal with the uncertainty of future conditions (inflows, demands, etc.). Even stochastic extensions of these methods (e.g. linear-quadratic-Gaussian control) necessitate such drastic oversimplifications of hydrosystems that may make the obtained results irrelevant to the real world problems. However, a Monte Carlo approach is feasible and can form a general methodology applicable to any type of hydrosystem. This methodology uses stochastic simulation to generate system inputs, either unconditional or conditioned on a prediction, if available, and represents the operation of the entire system through a simulation model as faithful as possible, without demanding a specific mathematical form that would imply oversimplifications. Such representation fully respects the physical constraints, while at the same time it evaluates the system operation constraints and objectives in probabilistic terms, and derives their distribution functions and statistics through Monte Carlo simulation. As the performance criteria of a hydrosystem operation will generally be highly nonlinear and highly nonconvex functions of the control variables, a second Monte Carlo procedure, implementing stochastic optimization, is necessary to optimize system performance and evaluate the control variables of the system. The latter is facilitated if the entire representation is parsimonious, i.e. if the number of control variables is kept at a minimum by involving a suitable system parameterization. The approach is illustrated through three examples for (a) a hypothetical system of two reservoirs

    A typical modulated pulse bathymetric lidar system is investigated by simulation using a modulated pulse lidar simulation system. In the simulation, the return signal is generated by Monte Carlo method with modulated pulse propagation model and processed by mathematical tools like cross-correlation and digital filter. Computer simulation results incorporating the modulation detection scheme reveal a significant suppression of the water backscattering signal and corresponding target contrast enhancement. More simulation experiments are performed with various modulation and reception variables to investigate the effect of them on the bathymetric system performance.

    Full Text Available We implement gradient estimation techniques for sensitivity analysis of option pricing which can be efficiently employed in Monte Carlo simulation. Using these techniques we can simultaneously obtain an estimate of the option value together with the estimates of sensitivities of the option value to various parameters of the model. After deriving the gradient estimates we incorporate them in an iterative stochastic approximation algorithm for pricing an option with early exercise features. We illustrate the procedure using an example of an American call option with a single dividend that is analytically tractable. In particular we incorporate estimates for the gradient with respect to the early exercise threshold level.

    A procedure for performing Monte Carlo calculations of plasmas with an arbitrary level of degeneracy is outlined. It has possible applications in inertial confinement fusion and astrophysics. Degenerate particles are initialised according to the Fermi–Dirac distribution function, and scattering is via a Pauli blocked binary collision approximation. The algorithm is tested against degenerate electron–ion equilibration, and the degenerate resistivity transport coefficient from unmagnetised first order transport theory. The code is applied to the cold fuel shell and alpha particle equilibration problem of inertial confinement fusion.

    International Nuclear Information System (INIS)

    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

Finally we consider Markov chains with continuous state (but discrete time), transition probabilities and random walks, which are the main piece of this work. The applications are: diffusion and advection equations, and the linear transport equation with scattering

    In this work we propose a new approach for the numerical simulation of kinetic equations through Monte Carlo schemes. We introduce a new technique which permits to reduce the variance of particle methods through a matching with a set of suitable macroscopic moment equations. In order to guarantee that the moment equations provide the correct solutions, they are coupled to the kinetic equation through a non equilibrium term. The basic idea, on which the method relies, consists in guiding the particle positions and velocities through moment equations so that the concurrent solution of the moment and kinetic models furnishes the same macroscopic quantities.

    Particle transport calculations in highly dimensional and physically complex geometries, such as detector calibration, radiation shielding, space reactors, and oil-well logging, generally require Monte Carlo transport techniques. Monte Carlo particle transport can be performed on a variety of computers ranging from APOLLOs to VAXs. Some of the hardware and software developments, which now permit Monte Carlo methods to be routinely used, are reviewed in this paper. The development of inexpensive, large, fast computer memory, coupled with fast central processing units, permits Monte Carlo calculations to be performed on workstations, minicomputers, and supercomputers. The Monte Carlo renaissance is further aided by innovations in computer architecture and software development. Advances in vectorization and parallelization architecture have resulted in the development of new algorithms which have greatly reduced processing times. Finally, the renewed interest in Monte Carlo has spawned new variance reduction techniques which are being implemented in large computer codes. 45 refs.

A doença mais transplantada foi o ceratocone por ser a doença mais incidente e não pelo fato de termos maior oferta de córneas doadoras idosas como suspeitávamos inicialmente. Quanto às médias etária e de tempo de preservação das córneas utilizadas houve preferência estatisticamente significativa pelo uso de córneas mais jovens nos casos de ceratopatia bolhosa.

    International Nuclear Information System (INIS)

    We study different Monte-Carlo methods for solving radiative transfer problems, and particularly Fleck's Monte-Carlo method. We first give the different time-discretization schemes and the corresponding stability criteria. Then we write the temperature variance as a function of the variances of temperature and absorbed energy at the previous time step. Finally we obtain some stability criteria for the Monte-Carlo method in the stationary case

    In mathematical finance, the sensitivities of option prices to various market parameters, also known as the “Greeks”, reflect the exposure to different sources of risk. Computing these is essential to predict the impact of market moves on portfolios and to hedge them adequately. This is commonly done using Monte Carlo simulations. However, obtaining accurate estimates of the Greeks can be computationally costly. Multilevel Monte Carlo offers complexity improvements over standard Monte Carl...

    2010-11-17

    Discrete Diffusion Monte Carlo (DDMC) is a technique for increasing the efficiency of Implicit Monte Carlo radiative-transfer simulations. In this paper, we develop an extension of DDMC for frequency-dependent radiative transfer. We base our new DDMC method on a frequency-integrated diffusion equation for frequencies below a specified threshold. Above this threshold we employ standard Monte Carlo. With a frequency-dependent test problem, we confirm the increased efficiency of our new DDMC technique.

  18. Unbiased combinations of nonanalog Monte Carlo techniques and fair games

    International Nuclear Information System (INIS)

    Historically, Monte Carlo variance reduction techniques have developed one at a time in response to calculational needs. This paper provides the theoretical basis for obtaining unbiased Monte Carlo estimates from all possible combinations of variance reduction techniques. Hitherto, the techniques have not been proven to be unbiased in arbitrary combinations. The authors are unaware of any Monte Carlo techniques (in any linear process) that are not treated by the theorem herein. (author)

    We present a new combinatorial method for the calculation of the nuclear level density. It is based on a Monte Carlo technique, in order to avoid a direct counting procedure which is generally impracticable for high-A nuclei. The Monte Carlo simulation, making use of the Metropolis sampling scheme, allows a computationally fast estimate of the level density for many fermion systems in large shell model spaces. We emphasize the advantages of this Monte Carlo approach, particularly concerning t...

    MCNPX (Monte Carlo N-Particle eXtended) is a general-purpose Monte Carlo radiation transport code with three-dimensional geometry and continuous-energy transport of 34 particles and light ions. It contains flexible source and tally options, interactive graphics, and support for both sequential and multi-processing computer platforms. MCNPX is based on MCNP4B, and has been upgraded to most MCNP5 capabilities. MCNP is a highly stable code tracking neutrons, photons and electrons, and using evaluated nuclear data libraries for low-energy interaction probabilities. MCNPX has extended this base to a comprehensive set of particles and light ions, with heavy ion transport in development. Models have been included to calculate interaction probabilities when libraries are not available. Recent additions focus on the time evolution of residual nuclei decay, allowing calculation of transmutation and delayed particle emission. MCNPX is now a code of great dynamic range, and the excellent neutronics capabilities allow new opportunities to simulate devices of interest to experimental particle physics; particularly calorimetry. This paper describes the capabilities of the current MCNPX version 2.6.C, and also discusses ongoing code development.

  8. Quantum Monte Carlo for atoms and molecules

    International Nuclear Information System (INIS)

    The diffusion quantum Monte Carlo with fixed nodes (QMC) approach has been employed in studying energy-eigenstates for 1--4 electron systems. Previous work employing the diffusion QMC technique yielded energies of high quality for H2, LiH, Li2, and H2O. Here, the range of calculations with this new approach has been extended to include additional first-row atoms and molecules. In addition, improvements in the previously computed fixed-node energies of LiH, Li2, and H2O have been obtained using more accurate trial functions. All computations were performed within, but are not limited to, the Born-Oppenheimer approximation. In our computations, the effects of variation of Monte Carlo parameters on the QMC solution of the Schroedinger equation were studied extensively. These parameters include the time step, renormalization time and nodal structure. These studies have been very useful in determining which choices of such parameters will yield accurate QMC energies most efficiently. Generally, very accurate energies (90--100% of the correlation energy is obtained) have been computed with single-determinant trail functions multiplied by simple correlation functions. Improvements in accuracy should be readily obtained using more complex trial functions

  9. Monte Carlo generators in ATLAS software

    International Nuclear Information System (INIS)

    This document describes how Monte Carlo (MC) generators can be used in the ATLAS software framework (Athena). The framework is written in C++ using Python scripts for job configuration. Monte Carlo generators that provide the four-vectors describing the results of LHC collisions are written in general by third parties and are not part of Athena. These libraries are linked from the LCG Generator Services (GENSER) distribution. Generators are run from within Athena and the generated event output is put into a transient store, in HepMC format, using StoreGate. A common interface, implemented via inheritance of a GeneratorModule class, guarantees common functionality for the basic generation steps. The generator information can be accessed and manipulated by helper packages like TruthHelper. The ATLAS detector simulation as well access the truth information from StoreGate1. Steering is done through specific interfaces to allow for flexible configuration using ATLAS Python scripts. Interfaces to most general purpose generators, including: Pythia6, Pythia8, Herwig, Herwig++ and Sherpa are provided, as well as to more specialized packages, for example Phojet and Cascade. A second type of interface exist for the so called Matrix Element generators that only generate the particles produced in the hard scattering process and write events in the Les Houches event format. A generic interface to pass these events to Pythia6 and Herwig for parton showering and hadronisation has been written.

  10. Information Geometry and Sequential Monte Carlo

    CERN Document Server

    Sim, Aaron; Stumpf, Michael P H

    2012-01-01

    This paper explores the application of methods from information geometry to the sequential Monte Carlo (SMC) sampler. In particular the Riemannian manifold Metropolis-adjusted Langevin algorithm (mMALA) is adapted for the transition kernels in SMC. Similar to its function in Markov chain Monte Carlo methods, the mMALA is a fully adaptable kernel which allows for efficient sampling of high-dimensional and highly correlated parameter spaces. We set up the theoretical framework for its use in SMC with a focus on the application to the problem of sequential Bayesian inference for dynamical systems as modelled by sets of ordinary differential equations. In addition, we argue that defining the sequence of distributions on geodesics optimises the effective sample sizes in the SMC run. We illustrate the application of the methodology by inferring the parameters of simulated Lotka-Volterra and Fitzhugh-Nagumo models. In particular we demonstrate that compared to employing a standard adaptive random walk kernel, the SM...

  11. Quantum Monte Carlo Calculations of Neutron Matter

    Carlson, J; Ravenhall, D G

    2003-01-01

    Uniform neutron matter is approximated by a cubic box containing a finite number of neutrons, with periodic boundary conditions. We report variational and Green's function Monte Carlo calculations of the ground state of fourteen neutrons in a periodic box using the Argonne $\\vep $ two-nucleon interaction at densities up to one and half times the nuclear matter density. The effects of the finite box size are estimated using variational wave functions together with cluster expansion and chain summation techniques. They are small at subnuclear densities. We discuss the expansion of the energy of low-density neutron gas in powers of its Fermi momentum. This expansion is strongly modified by the large nn scattering length, and does not begin with the Fermi-gas kinetic energy as assumed in both Skyrme and relativistic mean field theories. The leading term of neutron gas energy is ~ half the Fermi-gas kinetic energy. The quantum Monte Carlo results are also used to calibrate the accuracy of variational calculations ...

  12. Reactor perturbation calculations by Monte Carlo methods

    International Nuclear Information System (INIS)

    Whilst Monte Carlo methods are useful for reactor calculations involving complicated geometry, it is difficult to apply them to the calculation of perturbation worths because of the large amount of computing time needed to obtain good accuracy. Various ways of overcoming these difficulties are investigated in this report, with the problem of estimating absorbing control rod worths particularly in mind. As a basis for discussion a method of carrying out multigroup reactor calculations by Monte Carlo methods is described. Two methods of estimating a perturbation worth directly, without differencing two quantities of like magnitude, are examined closely but are passed over in favour of a third method based on a correlation technique. This correlation method is described, and demonstrated by a limited range of calculations for absorbing control rods in a fast reactor. In these calculations control rod worths of between 1% and 7% in reactivity are estimated to an accuracy better than 10% (3 standard errors) in about one hour's computing time on the English Electric KDF.9 digital computer.

  15. Feasibility study of CaSO4:Eu, CaSO4:Eu,Ag and CaSO4:Eu,Ag(NP) as thermoluminescent dosimeters

    International Nuclear Information System (INIS)

    This work evaluates the dosimetric properties of crystals of CaSO4 doped with unusual elements, such as europium (Eu) and silver (Ag), including their nanoparticle forms, after the incorporation of glass or Teflon and compares them with well-known thermoluminescent dosimeters (TLD). X-ray diffraction analyses showed that samples of doped CaSO4 exhibit only a single phase corresponding to the crystal structure of anhydrite. Optical spectroscopy confirmed the presence of Eu3+ in the crystal matrix and a luminescent gain due the presence of silver nanoparticles. The composites showed thermoluminescent emission glow curves, with a single peak centered at approximately 200 °C for pellets with Teflon and at 230 °C for pellets with glass. The dosimeters based on calcium sulfate doped with europium and silver nanoparticles provided the most intense thermoluminescent (TL) emission of the composites studied. In comparison with commercial TLD, such as LiF:Mg,Ti and CaSO4:Dy, the CaSO4:Eu,Ag(NP)+glass produced in this work presented similar low detection limits and higher sensitivity. The new methods for the preparation of dosimeters and the incorporation of glass are shown to be viable because all of the samples presented a linear, reproducible and first order kinetic TL emission. - Highlights: • Thermoluminescent properties of CaSO4 doped with Eu, Ag and Ag nanoparticles were evaluated. • Crystals were grown using a production route based in the Yamashita method. • Glass or Teflon was incorporate to the crystals in order to obtain composites. • The TL responses of the composites are proportional to the dose absorbed. • The CaSO4:Eu,Ag(NP) + glass has potential to be used as a thermoluminescent dosimeter

Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio.

It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

    Full Text Available Relatamos o caso de uma mulher de 30 anos com quadro de fraqueza muscular nos membros inferiores com predomínio distal com início há 7 anos. Na evolução apresentou fraqueza muscular nos membros superiores. O exame físico mostrava nervos cranianos sem alterações, hipotrofia bilateral de quadriceps e interósseos dos pés, redução da força muscular mais intensa em tibiais anteriores e interósseos dorsais dos pés e reflexos tendinosos globalmente hipoativos. Foi realizado teste de estimulação repetitiva que mostrou decremento maior que 10% no nervo fibular e ulnar. A dosagem de anticorpos anti-receptor de acetilcolina foi positiva. Tomografia computadorizada de tórax foi normal. Dosagem de hormônios tireoidianos mostrou evidências laboratoriais de hipertireoidismo, porém sem manifestações clínicas. Foi iniciado tratamento com piridostigmina havendo melhora importante do quadro clínico. A fraqueza distal é um sintoma inicial raro na miastenia grave (MG. Contudo, a MG deve entrar no diagnóstico diferencial de doenças que cursam com fraqueza muscular distal de membros superiores ou inferiores.

    Full Text Available El edema pulmonar postobstructivo (EPPO es una complicación postoperatoria cuyo manejo adecuado depende de un diagnóstico etiológico correcto. El EPPO se clasifica en dos tipos. El tipo I es secundario a la obstrucción aguda de la vía aérea superior. Por su parte, el tipo II ocurre luego de corregir quirúrgicamente una obstrucción crónica de la vía aérea. Fisiopatológicamente, el mecanismo que explica el cuadro es una disminución marcada de la presión intersticial en el nivel pericapilar pulmonar resultante de la inspiración forzada. Lo anterior produce fuga capilar y el consecuente edema de pulmón. El manejo de este cuadro requiere de soporte respiratorio que incluye ventilación mecánica e incluso presión positiva al final de la espiración (PEEP. El pronóstico es muy bueno si el diagnóstico es correcto y oportuno. Se reportan 3 casos que ilustran la entidad, su diagnóstico y manejo.

    1975-02-01

    The report contains sections containing descriptions of the MORSE and PICTURE codes, input descriptions, sample problems, deviations of the physical equations and explanations of the various error messages. The MORSE code is a multipurpose neutron and gamma-ray transport Monte Carlo code. Time dependence for both shielding and criticality problems is provided. General three-dimensional geometry may be used with an albedo option available at any material surface. The PICTURE code provide aid in preparing correct input data for the combinatorial geometry package CG. It provides a printed view of arbitrary two-dimensional slices through the geometry. By inspecting these pictures one may determine if the geometry specified by the input cards is indeed the desired geometry. 23 refs. (WRF)

  11. Monte Carlo Implementation of Polarized Hadronization

    Matevosyan, Hrayr H; Thomas, Anthony W

    2016-01-01

    We study the polarized quark hadronization in a Monte Carlo (MC) framework based on the recent extension of the quark-jet framework, where a self-consistent treatment of the quark polarization transfer in a sequential hadronization picture has been presented. Here, we first adopt this approach for MC simulations of hadronization process with finite number of produced hadrons, expressing the relevant probabilities in terms of the eight leading twist quark-to-quark transverse momentum dependent (TMD) splitting functions (SFs) for elementary $q \\to q'+h$ transition. We present explicit expressions for the unpolarized and Collins fragmentation functions (FFs) of unpolarized hadrons emitted at rank two. Further, we demonstrate that all the current spectator-type model calculations of the leading twist quark-to-quark TMD SFs violate the positivity constraints, and propose quark model based ansatz for these input functions that circumvents the problem. We validate our MC framework by explicitly proving the absence o...

  12. Helminthiases in Montes Claros. Preliminary survey

    1976-04-01

    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.

  13. Commensurabilities between ETNOs: a Monte Carlo survey

    Many asteroids in the main and trans-Neptunian belts are trapped in mean motion resonances with Jupiter and Neptune, respectively. As a side effect, they experience accidental commensurabilities among themselves. These commensurabilities define characteristic patterns that can be used to trace the source of the observed resonant behaviour. Here, we explore systematically the existence of commensurabilities between the known ETNOs using their heliocentric and barycentric semimajor axes, their uncertainties, and Monte Carlo techniques. We find that the commensurability patterns present in the known ETNO population resemble those found in the main and trans-Neptunian belts. Although based on small number statistics, such patterns can only be properly explained if most, if not all, of the known ETNOs are subjected to the resonant gravitational perturbations of yet undetected trans-Plutonian planets. We show explicitly that some of the statistically significant commensurabilities are compatible with the Planet Nin...

  14. Hybrid algorithms in quantum Monte Carlo

    International Nuclear Information System (INIS)

    With advances in algorithms and growing computing powers, quantum Monte Carlo (QMC) methods have become a leading contender for high accuracy calculations for the electronic structure of realistic systems. The performance gain on recent HPC systems is largely driven by increasing parallelism: the number of compute cores of a SMP and the number of SMPs have been going up, as the Top500 list attests. However, the available memory as well as the communication and memory bandwidth per element has not kept pace with the increasing parallelism. This severely limits the applicability of QMC and the problem size it can handle. OpenMP/MPI hybrid programming provides applications with simple but effective solutions to overcome efficiency and scalability bottlenecks on large-scale clusters based on multi/many-core SMPs. We discuss the design and implementation of hybrid methods in QMCPACK and analyze its performance on current HPC platforms characterized by various memory and communication hierarchies.

  15. Nuclear reactions in Monte Carlo codes

    Ferrari, Alfredo

    2002-01-01

    The physics foundations of hadronic interactions as implemented in most Monte Carlo codes are presented together with a few practical examples. The description of the relevant physics is presented schematically split into the major steps in order to stress the different approaches required for the full understanding of nuclear reactions at intermediate and high energies. Due to the complexity of the problem, only a few semi-qualitative arguments are developed in this paper. The description will be necessarily schematic and somewhat incomplete, but hopefully it will be useful for a first introduction into this topic. Examples are shown mostly for the high energy regime, where all mechanisms mentioned in the paper are at work and to which perhaps most of the readers are less accustomed. Examples for lower energies can be found in the references. (43 refs) .

  16. Monte Carlo modeling and meteor showers

    International Nuclear Information System (INIS)

    Prediction of short lived increases in the cosmic dust influx, the concentration in lower thermosphere of atoms and ions of meteor origin and the determination of the frequency of micrometeor impacts on spacecraft are all of scientific and practical interest and all require adequate models of meteor showers at an early stage of their existence. A Monte Carlo model of meteor matter ejection from a parent body at any point of space was worked out by other researchers. This scheme is described. According to the scheme, the formation of ten well known meteor streams was simulated and the possibility of genetic affinity of each of them with the most probable parent comet was analyzed. Some of the results are presented

  18. Monte Carlo Exploration of Warped Higgsless Models

    Hewett, J L; Rizzo, T G

    2004-01-01

    We have performed a detailed Monte Carlo exploration of the parameter space for a warped Higgsless model of electroweak symmetry breaking in 5 dimensions. This model is based on the $SU(2)_L\\times SU(2)_R\\times U(1)_{B-L}$ gauge group in an AdS$_5$ bulk with arbitrary gauge kinetic terms on both the Planck and TeV branes. Constraints arising from precision electroweak measurements and collider data are found to be relatively easy to satisfy. We show, however, that the additional requirement of perturbative unitarity up to the cut-off, $\\simeq 10$ TeV, in $W_L^+W_L^-$ elastic scattering in the absence of dangerous tachyons eliminates all models. If successful models of this class exist, they must be highly fine-tuned.

  19. Variable length trajectory compressible hybrid Monte Carlo

    2016-01-01

    Hybrid Monte Carlo (HMC) generates samples from a prescribed probability distribution in a configuration space by simulating Hamiltonian dynamics, followed by the Metropolis (-Hastings) acceptance/rejection step. Compressible HMC (CHMC) generalizes HMC to a situation in which the dynamics is reversible but not necessarily Hamiltonian. This article presents a framework to further extend the algorithm. Within the existing framework, each trajectory of the dynamics must be integrated for the same amount of (random) time to generate a valid Metropolis proposal. Our generalized acceptance/rejection mechanism allows a more deliberate choice of the integration time for each trajectory. The proposed algorithm in particular enables an effective application of variable step size integrators to HMC-type sampling algorithms based on reversible dynamics. The potential of our framework is further demonstrated by another extension of HMC which reduces the wasted computations due to unstable numerical approximations and corr...
