    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.

  9. 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.

Analisaram-se, além dos dados de 20 anos de produções sucessivas, as características das sementes e o aspecto vegetativo. O café 'Mundo Novo' e o 'Bourbon Amarelo' confirmaram as informações já anteriormente obtidas sobre a sua capacidade produtiva. A análise das produções anuais indicou que o café mais produtivo, isto é, o Mundo Novo, apresentou uma oscilação maior de produção. Todos os cultivares apresentaram tendência de decréscimo de produção após o décimo quarto ano de colheitas sucessivas . Verificou-se uma correlação positiva significativa entre as produções acumuladas de quatro e 20 anos, o que confirma resultados anteriores sobre a eficiência da seleção precoce no cafeeiro.The performance of ten cultivars of Coffea arabica is reported. The trial was established in 1949 in the Experimental Station of Monte Alegre do Sul and the yields recorded during 20 years. The 'Mundo Novo' and 'Bourbon Amarelo' confirmed previous reports about their high yielding capacity. The analysis of annual yields indicated that the better yielding cultivar showed a more intense cycle of bearing. Yield increased until the fourth crop when the biennial cycle of bearing started. The top yield was reached after 14 years. From this time on there was a tendency of decreasing the yield. A significant correlation was found between the cumulative yields of the four and 20 years of sucessive crops. This positive correlation confirms previous results about the efficiency of early selection in coffee.

  14. 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

  1. Determination of the frequency of polymorphisms in genes related to the genome stability maintenance of the population residing at Monte Alegre, PA (Brazil) municipality

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    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)

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 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.

    2007-06-01

    This study presents the effects of citizen participation on integrated solid waste management. Porto Alegre was chosen as the area of study since its system is a good example for developing countries, based on the partnership between local government and the former scavengers' association that implements selective collection in the city. A life-cycle approach was used to estimate environmental loadings and economic costs based on solid waste generation, and a survey assessment tool was used to analyse social aspects. The results showed a decrease in environmental and economic impacts in the current situation, allowing Porto Alegre to have one of the most affordable integrated solid waste management systems in Brazil. The survey assessment pointed out that public campaign changed the perceptions and practices of most of Porto Alegre's citizens regarding solid waste management. On the other hand, it also pointed out that citizens need more education to increase their participation. Therefore, more research is needed to increase cooperation among all stakeholders, improve citizen participation, and consequently, further decrease the environmental impacts and economic costs.

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

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.

    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)

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.

Group 1 (G1) consisted of 142 participants (living with their families) and Group 2 (G2) of 155 institutionalized individuals. All were individually interviewed and answered the Stressing Events Inventory for Children/Adolescents. The most frequent stressing events for the sample were: follow orders given by the parents (85.2%); quarrels with friends (72.9%); death of relatives (71.8%); failure at school (69.2%); and rivalry of siblings (68%). Student's t-test revealed significant difference between groups (p 0.05). The high frequency and strong impact of stressing events reveal the situation of social and familiar vulnerability, presence of violence and lack of resources in the whole group. PMID:19197420

  6. Geologic and geomorphologic controls of the kaolin deposits of Campo Alegre basin (SC-Brazil)

    International Nuclear Information System (INIS)

    The most important kaolin deposits from Campo Alegre region (S C) were formed by the conjunction of at least one hydrothermal phase followed by many others weathering, supergenic, phases. Possibly deposits formed by only one of these processes exist, but these deposits shall be small and smaller than those mined today. Besides kaolinization, illitization/muscovitization and silicification, hydrothermalism also generated pyritized and propilitized zones, with quartz + chlorite. Together, hipogenic alterations related to kaolin deposits are very similar to alterations of high sulfidation epigenetic volcanogenic gold deposits. Most part of the biggest kaolin mines from the southern part of Campo Alegre Basin are distributed along a 13 Km long and 0,5 Km width bent zone that is parallel to structural alignments that point out the eastern Basin border. This zone was originated by deformation that has inclined and broken rocks, generating a fault system alongside and parallel to structural lineaments. This fault system has made possible the ascent of hydrothermal hot aqueous fluids and of diqueform intrusions that caused hydrothermalism genetically related to kaolin deposits. Gamma spectrometry may indicate hydro thermalized zones. Although the potassium equivalent rock contents, derived from aerial gamma spectrometry of the mine regions, varies from a minimum of 2,07% to a maximum of 3,78%, 17 of the 20 mines are on high grade regions, with equivalent potassium contents grater than 3,04% and lower than 3,58%. The 'F factor' ((K.U)/Th) seems to indicate hydro thermalized zones better than potassium equivalent rock contents. Practically all the biggest mines on region are placed where 'F factor' is large, bigger than 10,05% and lower than 13,70%. The biggest mines are restricted to regions with altitudes between 950 and 1060 m. The average altitude of 23 mines is 1012,1+-13,8 m.

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

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.

Se considera que la intercalación de estos textos, más allá degenerar el suspenso (como propone Tomás Escajadillo, o poner en evidenciala intensa verosimilitud del universo representado —al ser untipo de cuentística típica del referente que Alegría representa literariamente(como señala Antonio Cornejo Polar— tienen como función laconstrucción de un sujeto heterogéneo y popular distinto al narradormonológico y grafocentrista. En tal sentido, siguiendo a Huaytán Martínez,se propone que la incorporación en estas novelas de relatos deraíz oral establecen vasos comunicantes entre la narrativa indigenista deCiro Alegría y el género testimonial.

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

    Full Text Available The 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.

    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.

    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 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.

We conducted a population-based prospective study focusing on oral health in Porto Alegre, south Brazil, and herein we describe its methodology and discuss directions for further research. The cohort was established in 2001 using a multistage probability sample of 1,465 toothed and 121 edentulous subjects. A 5-year follow-up was performed in 2006 that included 755 individuals. The main aim of this study was to determine the pattern and risk factors for periodontal disease progression and tooth loss incidence. A full-mouth protocol was used including periodontal assessments at six sites per tooth. Primary outcomes were periodontal attachment loss and tooth loss. Oral mucosal lesions, dental plaque, gingivitis, supragingival calculus, probing depths, gingival recession, and dental caries were also assessed. This is the first population-based cohort study to focus on periodontal disease in Latin America. Findings will contribute to our understanding of the epidemiology of periodontal disease and provide valuable data for the planning and implementation of preventive and therapeutic strategies.

    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.

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.

  13. 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)

    Full Text Available Heavy metals, like lead (Pb, are subproducts of industrial activities; however, in recent years, studies have shown that even in non-industrial areas, elevated concentrations of this element have been found. In this study, Pb concentrations were measured in 20 composite samples of urban sediments collected in an urban watershed of 4.85 km² with three types of soil use (commercial/residential, commercial and industrial in the city of Porto Alegre, RS, Brazil. Concentrations were determined by acid digestion (EPA 3050 of the 209 µm, 150 µm, 90 µm, 63 µm and 45 µm fractions followed by atomic emission spectrophotometry with inductively coupled plasma. Average values of 178.1 µg.g-¹ (± 332; 226.5 µg.g-¹ (± 500; 245.2 µg.g-¹ (± 454.1; 272.4 µg.g-¹ (± 497.3 and 251.5 µg.g-¹ (± 322.6 were obtained in the 209, 150, 90, 63 and 45 µm fractions, respectively. Concentrations of the metals studied were interpolated and represented geographically using Idrisi© Andes. Results show that the greatest concentrations are located in the commercial part of the study area, characterized as presenting high vehicle flow most of the day, with this being considered a potential source of lead. All concentrations were above that of the local background. Studies of this type are important because they make the establishment of control targets possible within sustainable management of water resources, allowing inferences regarding future pollution scenarios of local water resources.

    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

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.

    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...

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

    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.

    CERN Multimedia

    Leonardo Rossi

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

    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.

    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

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

  3. Pharmacy clerks' prescribing practices for STD patients in Porto Alegre, Brazil: missed opportunities for improving STD control.

    STDs are a significant public health problem in Brazil. A primary control strategy is the immediate treatment of symptomatic individuals. When services are unavailable, STD patients seek care in alternative settings. Probably the most frequently used settings are commercial pharmacies, where pharmacy clerks provide treatment, although Brazilian law prohibits selling antibiotics without prescription. Our objective was to evaluate prescribing practices by pharmacy clerks for STDs. We performed a cross-sectional study. Trained medical students visited 62 pharmacies in the city of Porto Alegre during March 2002. These were randomly chosen from a list of 863 registered pharmacies. The students presented to the pharmacy complaining of dysuria and urethral discharge. After obtaining a prescription, or not, they asked for additional instructions to be followed. Immediately after leaving the premises, the instructions were anonymously recorded. Of the 62 pharmacies visited, a clerk in 56 (90.3%, 95% confidence interval [CI]: 80.1%-96.4%) provided a prescription. Most frequently prescribed drugs were ampicillin with probenecide (29/51.8%) and rosoxacin (11/19.6%). Ministry of Health-recommended treatment was not suggested by any of the clerks. Forty-six additional recommendations were given. The use of condoms was the most frequent additional advice (42/46). Prescribing by pharmacy clerks is very prevalent in Porto Alegre. This may represent a lost opportunity for more comprehensive prevention effort (counselling, partner management, and diagnosing other STDs). Additionally, the most frequently prescribed drugs are not recommended by international or national health authorities for treatment of STDs, and none of these drugs covers chlamydia. We conclude that pharmacy clerks are a potentially important source of STD treatment and control but that their practices are in need of vast improvement. PMID:15117504

    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.

    International Nuclear Information System (INIS)

    This work describes an algorithm for absorbed dose evaluation in the region of X-ray diagnostic energy based on the response of CaSO4:Dy thermoluminescence powder detectors. The absorbed dose was calculated using Monte Carlo simulation code (MCSC) and then compared to the experimental TLD results for X-rays effective energies 60Co gamma radiation. In order to study the photon interaction in the matter, a cylindrical model of 1 cm3 was used. The gamma radiation source was placed at 100 cm to the object; the source is considered as an isotropic source of 60Co. The energy deposited into the cylindrical model was determined by the Monte Carlo N-particle (MCNPX) method. Measurements of the TL phosphors were obtained by irradiating the powder by gamma radiation. TL glow curve of CaSO4:Dy after gamma irradiated at a 1 Gy of absorbed dose was then obtained.

    Full Text Available A recurrent theme in political science links new forms of participatory democracy to citizens’ attitudes and their willingness to abide with their obligation to pay taxes. In this paper we examine how the citizens of Porto Alegre - Brazil view tax paying, from the perspective of material and non-material benefits. Usingsurvey data collected in Porto Alegre in 2003 with 687 interviews, we find that, overall poor sectors show a tendency to support tax paying because of the material benefits, while middle sectors also have supporting attitudes, but for non-material benefits. Through the use of logit regression we find empirical evidence of a connection between trust in participatory budget and citizenssupport for the municipal government.

    We present a cross-language C++/Python program for simulations of quantum mechanical systems with the use of Quantum Monte Carlo (QMC) methods. We describe a system for which to apply QMC, the algorithms of variational Monte Carlo and diffusion Monte Carlo and we describe how to implement theses methods in pure C++ and C++/Python. Furthermore we check the efficiency of the implementations in serial and parallel cases to show that the overhead using Python can be negligible.

    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.

    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 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.

    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.

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

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

  7. 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.)

    MCMini is a proof of concept that demonstrates the possibility for Monte Carlo neutron transport using OpenCL with a focus on performance. This implementation, written in C, shows that tracing particles and calculating reactions on a 3D mesh can be done in a highly scalable fashion. These results demonstrate a potential path forward for MCNP or other Monte Carlo codes.

    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.

  10. Monte Carlo Methods in Physics

    International Nuclear Information System (INIS)

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

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

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.

É uma doença clonal de células da linhagem mieloide, que apresenta características de mieloproliferação e de displasia. Os sinais e os sintomas são resultantes da infiltração de células monocíticas malignas em órgãos não hematopoéticos. Os sintomas mais comuns são febre, tosse, infecção, fraqueza, palidez, linfadenopatia, hepatoesplenomegalia, lesões cutâneas e manifestações hemorrágicas. Como a LMMJ exibe um curso clínico muito agressivo e responde pobremente à quimioterapia, o transplante de células-tronco hematopoéticas é a única modalidade terapêutica curativa. Neste estudo, relatamos o caso de um paciente do sexo masculino, com um ano e dez meses de idade, que compareceu na emergência do Hospital de Clínicas de Porto Alegre por apresentar febre, com diagnóstico prévio de mononucleose feito em outra Instituição.

    1994-11-01

    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.

Y por último, defiende la tesis del caso especial contra la objeción de que los argumentos prácticos generales cambiarían su carácter al pasar a formar parte del Derecho; para ello propugna concebir de manera procedimental la integración de los argumentos prácticos generales en el contexto jurídico.

    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.

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.

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

    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.

Uma das bactérias Gram-negativas de maior prevalência no ambiente nosocomial é a Klebsiella pneumoniae, capaz de expressar uma diversidade de enzimas de resistência, justificando seu monitoramento constante. OBJETIVO: Analisar a frequência fenotípica das enzimas betalactamases de espectro estendido (ESBL, cromossômicas (AmpC plasmidial, metalobetalactamase (MBL e Klebsiella pneumoniae carbapenemase (KPC oriundas de hospital de emergência em Porto Alegre (RS. MATERIAL E MÉTODO: Foram incluídos no estudo 58 isolados bacterianos com sensibilidade diminuída a cefalosporinas de terceira geração e/ou a cefoxitina. Nestas, foram aplicados os testes de disco-difusão compatíveis para as respectivas betalactamases. RESULTADOS: Encontrou-se elevada frequência de ESBL (48,3%, seguida por ESBL simultânea à AmpC plasmidial (15,5%, além de duas cepas com carbapenemases. DISCUSSÃO: O elevado índice de ESBL e ESBL/AmpC conduz à necessidade de uso terapêutico de carbapenens. Consequentemente, o uso massivo desses fármacos gera pressão seletiva que favorece o aparecimento de cepas mais resistentes, como as produtoras de carbapenemases (KPC e/ou MBL. As carbapenemases são muito relevantes devido à limitação terapêutica inerente e por seu potencial de disseminação. A resistência a todos os fármacos betalactâmicos usados no screening por disco-difusão pode ser um "sinalizador" laboratorial para a presença desses relevantes mecanismos de resistência. CONCLUSÃO: A pesquisa de fenótipos de resistência em Klebsiella é ferramenta fácil e exequível nos laboratórios de microbiologia, além de ser fundamental para o conhecimento da epidemiologia local das betalactamases, possibilitando a adequação da terapia antimicrobiana mais conveniente.INTRODUCTION: Worldwide, the incidence of

  11. 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.

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

    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.

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.

  5. 131I, 99mTc, 67Ga, 201Tl: evaluation of dose calibrators in nuclear medicine services of Porto Alegre City over a period of 5 years

    International Nuclear Information System (INIS)

    A programme for the comparison of activity measurements of radionuclides, administered to patients in Nuclear Medicine Services with the purpose of diagnosis or therapy, is being conducted under the coordination of the Radioprotection and Dosimetry Institute of the Brazilian Nuclear Energy Commission. All Nuclear Medicine Services in Brazil are required to employ dose calibrators, also known as activity meters, to measure the activity of solutions containing radionuclides prior to the administration of these radiopharmaceuticals to patients for the purpose of either diagnosis or treatment of illnesses. It is important, however, to measure with accuracy the activity of the administered radiopharmaceuticals to ensure images with the desired quality without submitting patients to unnecessary or insufficient radiation exposures. In the present work, measurements of the activity of samples of 131I, 99mTc, 67Ga and 201Tl, employing 5 ml radioactive samples in penicillin flasks, were conducted in the dose calibrators of the Nuclear Medicine Services of the city of Porto Alegre, from 2004 until 2008. The performance of the dose calibrators was evaluated by means of the Ratio R, obtained by dividing the mean value of the measurements obtained in each Nuclear Medicine Services, by the mean reference value measured for each of the radioactive samples in an activity meter previously calibrated by Radioprotection and Dosimetry Institute. Values of R between 0,90 and 1,10 are considered to be in accordance with the requirements specified in the Brazilian Regulation. The results were analysed to evaluate the compliance with the applicable regulation and were also compared to data available in the literature and obtained in other Brazilian cities and regions. The performance of the activity meters in Porto Alegre is shown to be very good, which contributes to ensure the radiological protection of patients submitted to diagnosis or therapy with radiopharmaceuticals.

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.

  10. Shell model Monte Carlo methods

    International Nuclear Information System (INIS)

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

  11. 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.)

    We introduce a new sequential Monte Carlo algorithm we call the particle cascade. The particle cascade is an asynchronous, anytime alternative to traditional particle filtering algorithms. It uses no barrier synchronizations which leads to improved particle throughput and memory efficiency. It is an anytime algorithm in the sense that it can be run forever to emit an unbounded number of particles while keeping within a fixed memory budget. We prove that the particle cascade is an unbiased mar...

    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. This propert...

    In this paper, we discuss the implications of a recently obtained equilibrium fluctuation-dissipation relation for the extension of the available Monte Carlo methods on the basis of the consideration of the Gibbs canonical ensemble to account for the existence of an anomalous regime with negative heat capacities C < 0. The resulting framework appears to be a suitable generalization of the methodology associated with the so-called dynamical ensemble, which is applied to the extension of two well-known Monte Carlo methods: the Metropolis importance sampling and the Swendsen-Wang cluster algorithm. These Monte Carlo algorithms are employed to study the anomalous thermodynamic behavior of the Potts models with many spin states q defined on a d-dimensional hypercubic lattice with periodic boundary conditions, which successfully reduce the exponential divergence of the decorrelation time τ with increase of the system size N to a weak power-law divergence \\tau \\propto N^{\\alpha } with α≈0.2 for the particular case of the 2D ten-state Potts model.

  18. Non statistical Monte-Carlo

    International Nuclear Information System (INIS)

    We have shown that the transport equation can be solved with particles, like the Monte-Carlo method, but without random numbers. In the Monte-Carlo method, particles are created from the source, and are followed from collision to collision until either they are absorbed or they leave the spatial domain. In our method, particles are created from the original source, with a variable weight taking into account both collision and absorption. These particles are followed until they leave the spatial domain, and we use them to determine a first collision source. Another set of particles is then created from this first collision source, and tracked to determine a second collision source, and so on. This process introduces an approximation which does not exist in the Monte-Carlo method. However, we have analyzed the effect of this approximation, and shown that it can be limited. Our method is deterministic, gives reproducible results. Furthermore, when extra accuracy is needed in some region, it is easier to get more particles to go there. It has the same kind of applications: rather problems where streaming is dominant than collision dominated problems

    Full Text Available La endocarditis infecciosa es una enfermedad de baja incidencia que en las últimas décadas mostró modificaciones respecto de su presentación, posibilidad diagnóstica y tratamiento. 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.

    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.

    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.

    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...

  6. 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.

    2016-06-01

    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

    1997-03-01

    A single scatter electron Monte Carlo code (SSMC), CREEP, has been written which bridges the gap between existing transport methods and modeling real physical processes. CREEP simulates ionization, elastic and bremsstrahlung events individually. Excitation events are treated with an excitation-only stopping power. The detailed nature of these simulations allows for calculation of backscatter and transmission coefficients, backscattered energy spectra, stopping powers, energy deposits, depth dose, and a variety of other associated quantities. Although computationally intense, the code relies on relatively few mathematical assumptions, unlike other charged particle Monte Carlo methods such as the commonly-used condensed history method. CREEP relies on sampling the Lawrence Livermore Evaluated Electron Data Library (EEDL) which has data for all elements with an atomic number between 1 and 100, over an energy range from approximately several eV (or the binding energy of the material) to 100 GeV. Compounds and mixtures may also be used by combining the appropriate element data via Bragg additivity.

    Full Text Available Driving under the influence of alcohol/ drugs (DUI is a well-established risk factor for traffic accidents, and men and women have different consumption patterns. 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.

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

    Full Text Available INTRODUCTION: Hospitals around the world have presented multiresistant Acinetobacter sp. outbreaks. The spread of these isolates that harbor an increasing variety of resistance genes makes the treatment of these infections and their control within the hospital environment more difficult. This study aimed to evaluate the occurrence and dissemination of Acinetobacter sp. multiresistant isolates and to identify acquired resistance genes. METHODS: We analyzed 274 clinical isolates of Acinetobacter sp. from five hospitals in Porto Alegre, RS, Brazil. We evaluated the susceptibility to antimicrobial, acquired resistance genes from Ambler's classes B and D, and performed molecular typing of the isolates using enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR technique. RESULTS: A high (68% percentage of multiresistant isolates of Acinetobacter sp. was observed, and 69% were resistant to carbapenems. We identified 84% of isolates belonging to species A. baumannii because they presented the gene blaOXA-51. The gene blaOXA-23 was detected in 62% of the isolates, and among these, 98% were resistant to carbapenems. Using the ERIC-PCR technique, we identified clones of Acinetobacter sp. spread among the four hospitals analyzed during the sampling period. CONCLUSIONS: The data indicate the dissemination of Acinetobacter sp. isolates among hospitals and their permanence in the hospital after one year.

  8. Post-collisional multistage magmatism in the Ribeira mobile belt: geochemical and isotopic study of the Varzea Alegre intrusive complex, Espirito Santo, Brazil

    International Nuclear Information System (INIS)

    The Varzea Alegre Intrusive Complex (VAIC) corresponds to a post-collisional (late orogenic) pluton, related to the Brasiliano cycle, situated in the central part of the Espirito Santo State. It intrudes amphibolite to granulite facies metamorphic rocks of the Ribeira Belt. Two distinct domains were recognised in this zoned pluton: an inner domain with opx-gabbro, monzogabbro, diorite, quartz-diorite and megaporphyritic granite, and an outer one comprising an irregular and large ring of charnockitic rocks. Geochemical data from the former reveal medium to high-K calc-alkalic rocks, enriched in incompatible elements, mainly Ba, Sr, La, Ce and Pb and partially depleted in HFS elements. The charnockitic rocks show a high-K alkali-calcic signature; they are rich in Ba, K and some HFS elements, such a Zr, P and Nb. The incompatible element enrichment detected in the rocks of the VAIC has been reported for several intrusions from this part of the Ribeira Belt. A Rb-Sr isochronic age of 508± 12 Ma was determined for the megaporphyritic granite. The TDM model age varies from 1.3 Ga (opx-gabbro) to ca. 1.67 Ga (charnockitic rocks), which can be related to an important Mesoproterozoic crustal event. The calculated TCHUR model ages of the cogenetic opx-gabbros and intermediary rocks is ca. 1.0 Ga, interpreted as the time when the basic magma was extracted from the source. (author)

  9. Evidence of mingling between contrasting magmas in a deep plutonic environment: the example of Varzea Alegre, in the Ribeira Mobile Belt, Espirito Santo, Brazil

    International Nuclear Information System (INIS)

    At the end the geotectonic cycle that shaped the northern segment of the Ribeira Mobile Belt (Upper Proterozoic to Paleozoic age), a late to post-collisional set of plutonic complexes, consisting of a wide range of lithotypes, intruded all metamorphic units. The Varzea Alegre intrusive Complex is a post-collisional complex. The younger intrusion consists of an inversely zoned multistage structure envolved by a large early emplaced ring of megaporphyritic charnoenderbitic rocks. The combination if field, petrographic and geochemical data reveals the presence of at least two different series of igneous rocks. The first originated from the partial melting of the mantle. this was previously enriched in incompatible elements, low and intermediate REE and some HFS-elements. A second enrichment in LREE and incompatible elements in this series was due to the mingling with a crustal granitic magma. This mingling process changed the composition of the original tholeiitic magma towards a medium-K calc-alkalic magma to produce a suite of basic to intermediate rock types. The granitic magma from the second high-K, calc-alkalic suite originated from the partial melting of the continental crust, with strong influence of mantle-derived melts. (author)

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

  16. 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.)

    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

    Monte Carlo particle transport is often introduced primarily as a method to solve linear integral equations such as the Boltzmann transport equation. This paper discusses some common misconceptions about Monte Carlo methods that are often associated with an equation-based focus. Many of the misconceptions apply directly to standard Monte Carlo codes such as MCNP and some are worth noting so that one does not unnecessarily restrict future methods. - Highlights: Black-Right-Pointing-Pointer Adjoint variety and use from a Monte Carlo perspective. Black-Right-Pointing-Pointer Misconceptions and preconceived notions about statistical weight. Black-Right-Pointing-Pointer Reasons that an adjoint based weight window sometimes works well or does not. Black-Right-Pointing-Pointer Pulse height/probability of initiation tallies and 'the' transport equation. Black-Right-Pointing-Pointer Highlights unnecessary preconceived notions about Monte Carlo transport.

    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.

    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.

    Full Text Available Kaolin at Campo Alegre Basin, Santa Catarina State, Brazil was formed from alteration of volcanic acid rocks. Halloysite clays dominate the clay fraction of the matrix of the kaolin body, whereas a poorly crystalline kaolinite is abundant in veins. Some primary blocky structures have high amounts of illite, in one mine, but in general, only low contents of illite-smectite, illite, chlorite-vermiculite, vermiculite and quartz were identified in the clay fraction of the samples. Toward the top of the mines, hematite and lepidocrocite appear in horizontal red and ochre colored levels and the amount of kaolinite increases compared to halloysite. The vertical zoning of alteration levels, the changes in mineralogy, the positive correlation between depth and Cation Exchange Capacity of the clays, the preservation of different types of rock textures in the kaolin bodies, the dominant tube morphology of the halloysite clays indicate a supergene genesis for the deposits. Criteria to distinguish between supergene and hypogene kaolin are discussed. Transmission Electron Microscopy of the cross sections of halloysite tubes showed polygonal forms that are ascribed to be transitional between kaolinite and halloysite. It is proposed that some of the kaolinite of these deposits be inherited from the dehydration of halloysite tubes.O caolim da Bacia de Campo Alegre, Estado de Santa Catarina, Brasil, formou-se da alteração de rochas vulcânicas ácidas. A haloisita predomina na fração argila da matriz do corpo de caolim, enquanto a caolinita, de baixa cristalinidade, é abundante nos veios. Algumas estruturas em blocos, primários, têm altos teores de ilita em uma mina, mas no geral, somente foram identificadas, na fração argila das amostras, baixas quantidades de ilita-esmectita, ilita, clorita-vermiculita, vermiculita e quartzo. Em direção ao topo das minas aparecem hematita e lepidocrocita em níveis vermelhos e ocres e as quantidades de caolinita

    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.

  13. Use of Monte Carlo Methods in brachytherapy

    International Nuclear Information System (INIS)

    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.

    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.

  17. Importance iteration in MORSE Monte Carlo calculations

    International Nuclear Information System (INIS)

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

  2. Advanced computers and Monte Carlo

    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

  3. Guideline for radiation transport simulation with the Monte Carlo method

    International Nuclear Information System (INIS)

    Today, the photon and neutron transport calculations with the Monte Carlo method have been progressed with advanced Monte Carlo codes and high-speed computers. Monte Carlo simulation is rather suitable expression than the calculation. Once Monte Carlo codes become more friendly and performance of computer progresses, most of the shielding problems will be solved by using the Monte Carlo codes and high-speed computers. As those codes prepare the standard input data for some problems, the essential techniques for solving the Monte Carlo method and variance reduction techniques of the Monte Carlo calculation might lose the interests to the general Monte Carlo users. In this paper, essential techniques of the Monte Carlo method and the variance reduction techniques, such as importance sampling method, selection of estimator, and biasing technique, are described to afford a better understanding of the Monte Carlo method and Monte Carlo code.

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.

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

  17. Experience with the Monte Carlo Method

    International Nuclear Information System (INIS)

    Monte Carlo simulation of radiation transport provides a powerful research and design tool that resembles in many aspects laboratory experiments. Moreover, Monte Carlo simulations can provide an insight not attainable in the laboratory. However, the Monte Carlo method has its limitations, which if not taken into account can result in misleading conclusions. This paper will present the experience of this author, over almost three decades, in the use of the Monte Carlo method for a variety of applications. Examples will be shown on how the method was used to explore new ideas, as a parametric study and design optimization tool, and to analyze experimental data. The consequences of not accounting in detail for detector response and the scattering of radiation by surrounding structures are two of the examples that will be presented to demonstrate the pitfall of condensed

  2. Dosimetric properties of CaSO4: Dy thermoluminescent material

    International Nuclear Information System (INIS)

    The new ICRP regulations about radiological protection allows the different groups to study new high sensitivity thermoluminescent materials for dosimetric applications (personal and environmental). Different concentrations of Dy as dopant in the thermoluminescent material CaSO4 have been studied. The concentration usually encountered in bibliography for the CaSO4 is 0.1%. Our group have chosen the 1% Dy concentration due to its high sensitivity, the ratio for the CaSO4: Dy (1%) over the CaSO4: Dy (0.1%) is close to 3. The results obtained for the habitual set of tests (homogeneity, reproducibility, detection threshold, energy response and fading) reveals CaSO4: Dy (1%) as an excellent dosimetric material. We also present the good behavior of the CaSO4: Dy (0.1%) as a material for a retrospective dosimetry. (Author)

  5. Monte Carlo photon transport techniques

    International Nuclear Information System (INIS)

    The basis of Monte Carlo calculation of photon transport problems is the computer simulation of individual photon histories and their subsequent averaging to provide the quantities of interest. As the history of a photon is followed the values of variables are selected and decisions made by sampling known distributions using random numbers. The transport of photon is simulated by creation of particles from a defined source region, generally with a random initial orientation in space, with tracking of particles as they travel through the system, sampling the probability density functions for their interactions to evaluate their trajectories and energy deposition at different points in the system. The interactions determine the penetration and the motion of particles. The computational model, for radiation transport problems includes geometry and material specifications. Every computer code contains a database of experimentally obtained quantities, known as cross-sections that determine the probability of a particle interacting with the medium through which it is transported. Every cross-section is peculiar to the type and energy of the incident particle and to the kind of interaction it undergoes. These partial cross-sections are summed to form the total cross-section; the ratio of the partial cross-section to the total cross-section gives the probability of this particular interaction occurring. Cross-section data for the interaction types of interest must be supplied for each material present. The model also consists of algorithms used to compute the result of interactions (changes in particle energy, direction, etc.) based on the physical principles that describe the interaction of radiation with matter and the cross-section data provided

    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

    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.

  15. Successful vectorization - reactor physics Monte Carlo code

    International Nuclear Information System (INIS)

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

    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.

  2. Quantum Monte Carlo calculations of light nuclei

    International Nuclear Information System (INIS)

    Quantum Monte Carlo calculations using realistic two- and three-nucleon interactions are presented for nuclei with up to eight nucleons. We have computed the ground and a few excited states of all such nuclei with Greens function Monte Carlo (GFMC) and all of the experimentally known excited states using variational Monte Carlo (VMC). The GFMC calculations show that for a given Hamiltonian, the VMC calculations of excitation spectra are reliable, but the VMC ground-state energies are significantly above the exact values. We find that the Hamiltonian we are using (which was developed based on 3H, 4He, and nuclear matter calculations) underpredicts the binding energy of p-shell nuclei. However our results for excitation spectra are very good and one can see both shell-model and collective spectra resulting from fundamental many-nucleon calculations. Possible improvements in the three-nucleon potential are also be discussed

    2016-01-01

    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.

  5. 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

    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.

  18. Geodesic Monte Carlo on Embedded Manifolds.

    Science.gov (United States)

    Byrne, Simon; Girolami, Mark

    2013-12-01

    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.

  19. Interaction picture density matrix quantum Monte Carlo

    International Nuclear Information System (INIS)

    The recently developed density matrix quantum Monte Carlo (DMQMC) algorithm stochastically samples the N-body thermal density matrix and hence provides access to exact properties of many-particle quantum systems at arbitrary temperatures. We demonstrate that moving to the interaction picture provides substantial benefits when applying DMQMC to interacting fermions. In this first study, we focus on a system of much recent interest: the uniform electron gas in the warm dense regime. The basis set incompleteness error at finite temperature is investigated and extrapolated via a simple Monte Carlo sampling procedure. Finally, we provide benchmark calculations for a four-electron system, comparing our results to previous work where possible

  20. Monte Carlo modeling of Tajoura reactor

    International Nuclear Information System (INIS)

    From neutronics point of view, reactor modeling is concerned with the determination of the reactor neutronic parameters which can be obtained through the solution of the neutron transport equation. The attractiveness of the Monte Carlo method is in its capability of handling geometrically complicated problems and due to the nature of the method a large number of particles can be tracked from birth to death before any statistically significant results can be obtained. In this paper the MCNP, a Monte Carlo code, is implemented in the modeling of the Tajoura reactor. (author)

    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.

    International Nuclear Information System (INIS)

    A library of Monte Carlo subroutines has been developed for the purpose of design of neutron scattering instruments. Using small-angle scattering as an example, the philosophy and structure of the library are described and the programs are used to compare instruments at continuous wave (CW) and long-pulse spallation source (LPSS) neutron facilities. The Monte Carlo results give a count-rate gain of a factor between 2 and 4 using time-of-flight analysis. This is comparable to scaling arguments based on the ratio of wavelength bandwidth to resolution width

  4. Monte Carlo applications to radiation shielding problems

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    The precision of Radiosurgery Treatment planning systems is limited by the approximations of their algorithms and by their dosimetrical input data. This fact is especially important in small fields. However, the Monte Carlo methods is an accurate alternative as it considers every aspect of particle transport. In this work an acoustic neurinoma is studied by comparing the dose distribution of both a planning system and Monte Carlo. Relative shifts have been measured and furthermore, Dose-Volume Histograms have been calculated for target and adjacent organs at risk. (orig.)

    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.

    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.

    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.

    2015-07-01

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

  5. Coded aperture optimization using Monte Carlo simulations

    International Nuclear Information System (INIS)

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

  1. Development of Monte Carlo machine for particle transport problem

    International Nuclear Information System (INIS)

    Monte Carlo machine, Monte-4 has been developed to realize high performance computing of Monte Carlo codes for particle transport. The calculation for particle tracking in a complex geometry requires (1) classification of particles by the region types using multi-way conditional branches, and (2) determination whether intersections of particle paths with surfaces of the regions are on the boundaries of the regions or not, using nests of conditional branches. However, these procedures require scalar operations or unusual vector operations. Thus the speedup ratios have been low, i.e. nearly two times, in vector processing of Monte Carlo codes for particle transport on conventional vector processors. The Monte Carlo machine Monte-4 has been equipped with the special hardware called Monte Carlo pipelines to process these procedures with high performance. Additionally Monte-4 has been equipped with enhanced load/store pipelines to realize fast transfer of indirectly addressed data for the purpose of resolving imbalances between the performance of data transfers and arithmetic operations in vector processing of Monte Carlo codes on conventional vector processors. Finally, Monte-4 has a parallel processing capability with four processors to multiply the performance of vector processing. We have evaluated the effective performance of Monte-4 using production-level Monte Carlo codes such as vectorized KENO-IV and MCNP. In the performance evaluation, nearly ten times speedup ratios have been obtained, compared with scalar processing of the original codes. (author)

  15. 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.

    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...

  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. Coevolution Based Adaptive Monte Carlo Localization (CEAMCL

    Directory of Open Access Journals (Sweden)

    2008-11-01

    Full Text Available An adaptive Monte Carlo localization algorithm based on coevolution mechanism of ecological species is proposed. Samples are clustered into species, each of which represents a hypothesis of the robot's pose. Since the coevolution between the species ensures that the multiple distinct hypotheses can be tracked stably, the problem of premature convergence when using MCL in highly symmetric environments can be solved. And the sample size can be adjusted adaptively over time according to the uncertainty of the robot's pose by using the population growth model. In addition, by using the crossover and mutation operators in evolutionary computation, intra-species evolution can drive the samples move towards the regions where the desired posterior density is large. So a small size of samples can represent the desired density well enough to make precise localization. The new algorithm is termed coevolution based adaptive Monte Carlo localization (CEAMCL. Experiments have been carried out to prove the efficiency of the new localization algorithm.

  19. Monte Carlo simulation of gas Cerenkov detectors

    International Nuclear Information System (INIS)

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

  20. 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)

    The recently proposed fast lattice Monte Carlo (FLMC) simulations (with multiple occupancy of lattice sites (MOLS) and Kronecker δ-function interactions) give much faster/better sampling of configuration space than both off-lattice molecular simulations (with pair-potential calculations) and conventional lattice Monte Carlo simulations (with self- and mutual-avoiding walk and nearest-neighbor interactions) of polymers.[1] Quantitative coarse-graining of polymeric systems can also be performed using lattice models with MOLS.[2] Here we use several model systems, including polymer melts, solutions, blends, as well as confined and/or grafted polymers, to demonstrate the great advantages of FLMC simulations in the study of equilibrium properties of polymers.

    International Nuclear Information System (INIS)

    Four papers were presented by Group X-6 on April 22, 1980, at the Oak Ridge Radiation Shielding Information Center (RSIC) Seminar-Workshop on Theory and Applications of Monte Carlo Methods. 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

    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...

  4. 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.

  5. 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

    2016-04-01

    We show how lattice quantum Monte Carlo can be applied to the electronic properties of carbon nanotubes in the presence of strong electron-electron correlations. We employ the path-integral formalism and use methods developed within the lattice QCD community for our numerical work. Our lattice Hamiltonian is closely related to the hexagonal Hubbard model augmented by a long-range electron-electron interaction. We apply our method to the single-quasiparticle spectrum of the (3,3) armchair nanotube configuration, and consider the effects of strong electron-electron correlations. Our approach is equally applicable to other nanotubes, as well as to other carbon nanostructures. We benchmark our Monte Carlo calculations against the two- and four-site Hubbard models, where a direct numerical solution is feasible.

  7. 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

  8. A Monte Carlo solution to skyshine radiation

    International Nuclear Information System (INIS)

    A Monte Carlo method was used to calculate the skyshine doses from 2-ft exposure cell ceiling of an accelerator. Modifications were made to the Monte Carlo program MORSE code to perform this analysis. Adjoint mode calculations provided optimum Russian roulette and splitting parameters which were later used in the forward mode calculations. Russian roulette and splitting were used at the collision sites and at boundary crossings. Exponential transform was used for particle pathlength stretching. The TIGER code was used to generate the anisotropic source term and P5 Legendre expansion was used to compute the cross sections. Where negative fluxes occured at detector locations due to large angle scatterings, a macroscopic cross section data bank was used to make Klein-Nishina and pair production flux estimates. With the above modifications, sixty detectors at locations ranging from 10 to 300 ft from the cell wall showed good statistical responses (5 to 10% fsd)

    The dynamical critical exponent of the two-dimensional spin-flip Ising model is evaluated by a Monte Carlo renormalization group method involving a transformation in time. The results agree very well with a finite-size scaling analysis performed on the same data. The value of $z = 2.13 \\pm 0.01$ is obtained, which is consistent with most recent estimates.

    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.)

    ""Handbook of Markov Chain Monte Carlo"" brings together the major advances that have occurred in recent years while incorporating enough introductory material for new users of MCMC. Along with thorough coverage of the theoretical foundations and algorithmic and computational methodology, this comprehensive handbook includes substantial realistic case studies from a variety of disciplines. These case studies demonstrate the application of MCMC methods and serve as a series of templates for the construction, implementation, and choice of MCMC methodology.

  19. Simulated Annealing using Hybrid Monte Carlo

    OpenAIRE

    Salazar, Rafael; Toral, Raúl

    1997-01-01

    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.

  20. Coevolution Based Adaptive Monte Carlo Localization (CEAMCL)

    OpenAIRE

    2004-01-01

    An adaptive Monte Carlo localization algorithm based on coevolution mechanism of ecological species is proposed. Samples are clustered into species, each of which represents a hypothesis of the robot's pose. Since the coevolution between the species ensures that the multiple distinct hypotheses can be tracked stably, the problem of premature convergence when using MCL in highly symmetric environments can be solved. And the sample size can be adjusted adaptively over time according to the unce...

    2014-01-01

    We compute a Monte Carlo approximation of {\\pi} using importance sampling with shots coming out of a Mossberg 500 pump-action shotgun as the proposal distribution. 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.

  5. Topological zero modes in Monte Carlo simulations

    International Nuclear Information System (INIS)

    We present an improvement of global Metropolis updating steps, the instanton hits, used in a hybrid Monte Carlo simulation of the two-flavor Schwinger model with staggered fermions. These hits are designed to change the topological sector of the gauge field. In order to match these hits to an unquenched simulation with pseudofermions, the approximate zero mode structure of the lattice Dirac operator has to be considered explicitly. (orig.)

    We look at adaptive Markov chain Monte Carlo algorithms that generate stochastic processes based on sequences of transition kernels, where each transition kernel is allowed to depend on the history of the process. We show under certain conditions that the stochastic process generated is ergodic, with appropriate stationary distribution. We use this result to analyse an adaptive version of the random walk Metropolis algorithm where the scale parameter σ is sequentially adapted using a Robbins-...

  8. Tracklength biassing in Monte Carlo radiation transport

    International Nuclear Information System (INIS)

    Tracklength stretching is employed in deep penetration Monte Carlo studies for variance reduction. Incorporating a dependence of the biassing on the angular disposition of the track improves the procedure. Linear and exponential forms for this dependence are investigated here, using Spanier's self-learning technique. Suitable biassing parameters are worked out for representative shield systems, for use in practical simulations. Of the two, we find that the exponential scheme performs better. (orig.)

    2000-01-01

    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.

    Full Text Available Ainda pouco se conhece sobre as condições socioambientais que favorecem a permanência do Aedes aegypti em áreas urbanas e sua capacidade de transmissão de dengue. A proposta desse trabalho é localizar os casos da doença e a presença do vetor, e identificar fatores sócio-ambientais que caracterizam esses locais, através de técnicas de geoprocessamento, procurando desenvolver um modelo de prevenção de dengue. O vetor foi encontrado principalmente nas zonas sul e leste da cidade, apresentando uma grande dispersão no município, enquanto a maior parte dos casos está localizada na parte central da cidade. Os setores que apresentaram casos possuem características de alta renda. Por outro lado, nos setores com a presença de vetor são verificadas a predominância de casas e boa infraestrutura de saneamento. A diferença dos padrões de distribuição de casos e vetor assegurou para o ano de 2002 a ausência detransmissão do vírus no município.The social-environmental conditions that promote the continuity of Aedes aegypti in urban areas and its capacity for dengue transmission have yet to be determined. The aim of this work was to locate dengue cases and vector presence, then to identify social-environmental factors that characterize these sites, through Geographical Information Systems (GIS, with a view to developing a dengue fever prevention model. The vector was mainly located in south and east areas of the city, with a broad dispersion, while most of the cases were located in the central region of the city. The sectors with cases present characteristics of high income. Otherwise, sectors with vector present a predominance of houses and good sanitation infrastructure. The difference between cases and vector spatial patterns ensured for 2002 an absence of dengue transmission in the city.

  17. jTracker and Monte Carlo Comparison

    Science.gov (United States)

    Selensky, Lauren; SeaQuest/E906 Collaboration

    2015-10-01

    SeaQuest is designed to observe the characteristics and behavior of `sea-quarks' in a proton by reconstructing them from the subatomic particles produced in a collision. The 120 GeV beam from the main injector collides with a fixed target and then passes through a series of detectors which records information about the particles produced in the collision. However, this data becomes meaningful only after it has been processed, stored, analyzed, and interpreted. Several programs are involved in this process. jTracker (sqerp) reads wire or hodoscope hits and reconstructs the tracks of potential dimuon pairs from a run, and Geant4 Monte Carlo simulates dimuon production and background noise from the beam. During track reconstruction, an event must meet the criteria set by the tracker to be considered a viable dimuon pair; this ensures that relevant data is retained. As a check, a comparison between a new version of jTracker and Monte Carlo was made in order to see how accurately jTracker could reconstruct the events created by Monte Carlo. In this presentation, the results of the inquest and their potential effects on the programming will be shown. This work is supported by U.S. DOE MENP Grant DE-FG02-03ER41243.

  18. 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.

  19. 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

  20. Monte Carlo small-sample perturbation calculations

    International Nuclear Information System (INIS)

    Two different Monte Carlo methods have been developed for benchmark computations of small-sample-worths in simplified geometries. The first is basically a standard Monte Carlo perturbation method in which neutrons are steered towards the sample by roulette and splitting. One finds, however, that two variance reduction methods are required to make this sort of perturbation calculation feasible. First, neutrons that have passed through the sample must be exempted from roulette. Second, neutrons must be forced to undergo scattering collisions in the sample. Even when such methods are invoked, however, it is still necessary to exaggerate the volume fraction of the sample by drastically reducing the size of the core. The benchmark calculations are then used to test more approximate methods, and not directly to analyze experiments. In the second method the flux at the surface of the sample is assumed to be known. Neutrons entering the sample are drawn from this known flux and tracking by Monte Carlo. The effect of the sample or the fission rate is then inferred from the histories of these neutrons. The characteristics of both of these methods are explored empirically
