A BEM based on the Bézier/Bernstein polynomial for acoustic waveguide modelization
No full text42nd International Conference on Boundary Elements and other Mesh Reduction Methods, BEM/MRM 2019; ITeCons-University of CoimbraCoimbra; Portugal; 2 July 2019 through 4 July 2019; Code 155806. Publicado en WIT Transactions on Engineering Sciences, Vol 126This paper proposes a novel boundary element approach formulated on the Bézier–Bernstein basis to yield a geometry-independent field approximation. The proposed method is geometrically based on both computer aided design (CAD) and isogeometric analysis (IGA), but field variables are independently approximated from the geometry. This approach allows the appropriate approximation functions for the geometry and variable field to be chosen. We use the Bézier–Bernstein form of a polynomial as an approximation basis to represent both geometry and field variables. The solution of the element interpolation problem in the Bézier–Bernstein space defines generalised Lagrange interpolation functions that are used as element shape functions. The resulting Bernstein–Vandermonde matrix related to the Bézier–Bernstein interpolation problem is inverted using the Newton–Bernstein algorithm. The applicability of the proposed method is demonstrated by solving the Helmholtz equation over an unbounded region in a two-and-a-half dimensional (2.5D) domain.Ministerio de Economía y Competitividad BIA2016-75042-C2-1-

Cabazitaxel in metastatic prostate cancer
No full textTo the Editor: In the CARD trial reported by de Wit et al. (Dec. 26 issue),(1) 255 patients with metastatic castration-resistant prostate cancer who had previously received docetaxel and who had disease progression while receiving abiraterone or enzalutamide were randomly assigned to cabazitaxel or the other androgen-signaling-targeted inhibitor. Cabazitaxel significantly improved several clinical outcomes, including imaging-based progression-free survival and overall survival, as compared with hormonal treatment. This trial represents an important step forward in the understanding of appropriate advanced treatment in patients with metastatic castration-resistant prostate cancer. However, it should be noted that 61.2% of the patients received hormonal treatment . .
Towards a shared method to classify contaminated territories in the case of an accidental nuclear event: the PRIME project
No full textThe analysis of the management of the accidentally radioactive contaminated areas such as those around Chernobyl nuclear power plant highlights the fact that the current spatial classification methods hardly help in recovering proper use of the contaminated territory.
The cause is mainly to be searched for in the traditional construction of risks assessment methods; these methods rest on criteria defined by institutional experts, which are not applicable in practise because they are not shared by all the stakeholders involved in the management of the contaminated territories.
Opposite such top-down tentative management, local efforts supported by Non-Governmental Organizations to restore life in the contaminated area seem to be more fruitful but very time and resources consuming and limited to the specific areas where they are experimented. The aim of the PRIME project, in progress at the French Institute for Radioprotection and Nuclear Safety, is to mix the advantages of both approaches in building a multicriteria decision tool based on the territorial specificities.
The criteria of the method are chosen and weighted with representatives of the territory’s stakeholders (decision makers, local actors and experts) to warrant that all the points of view are taken into account and to enable the risk managers to choose the appropriate strategy in case of an accident involving radioactive substances.
The area chosen for the pilot study is a 50 km radius territory around the nuclear sites of Tricastin-Pierrelatte in the lower valley of Rhône (France). One of the exploration questions of the PRIME project is whether a multicriteria method may be an appropriate tool to treat the data and make them visible and accessible for all the stakeholders

Dynamics of change in the peri-urban landscape of Huerta de Valencia: the case of La Punta (Valencia)
No full textThis paper is a partial result of a wider research project that attempts to assess the changes in the urban and peri-urban fabric soils of the municipality of Valencia from 1944 to 2004. The research presented focuses on the analysis of the nature of the changes and the dynamics of these over time in the area of La Punta, a town administrated by the city of Valencia (Spain) and located in the district of Quatre Carreres. The methodology is based on the analysis and measurement of changes in land structure, in the land use, in the occupation of building and in the forested areas presented in the traditional structure of non-urban roads. The key to measure such changes have been the use of the Cadaster of 1929 1944; 1972; 1989; orthophoto collections from the Valencian Regional Library and evolution of mapping from the SIOSE. The most outstanding results refer to the surprising resilience of some elements of the structure of the Huerta de Valencia and the discovery and identification of landscapes (plural) result of the different dynamics of change.Temes Cordovez, RR.; Moya Fuero, A.

Desigualdades socioeconômicas na prevalência, consumo, início e cessação do tabagismo no Brasil: inquérito domiciliar nacional 2008
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Saúde Coletiva, Florianópolis, 2013.OBJETIVOS: Testar a associação da prevalência de tabagismo atual, consumo de cigarros, iniciação ao tabagismo, idade de início do uso e cessação do tabagismo no Brasil com as condições socioeconômicas da população. MÉTODOS: Trata-se de um inquérito nacional realizado em 2008 com 39.425 homens e mulheres. A amostragem foi por conglomerados em quatro estágios. Estimaram-se a prevalência, as taxas de iniciação e a cessação do tabagismo, número de cigarros industrializados e idade de início ajustados por sexo segundo as variáveis exploratórias. Foram calculadas as razões de prevalência (IC 95%) segundo cor da pele, renda domiciliar per capita, escolaridade e local de residência por meio da Regressão de Poisson, ajustando-se as medidas por faixa etária. RESULTADOS: Os resultados sugerem desigualdades socioeconômicas na prevalência, iniciação, idade de início e cessação do tabagismo em homens e mulheres. A escolaridade foi o indicador de desigualdade socioeconômica com maior magnitude de efeito nas variáveis estudadas, exceto o desfecho cessação do tabagismo nas mulheres, o qual não houve associação estatisticamente significante com escolaridade. A média de consumo de cigarros diários é maior entre os homens e mulheres com indicadores socioeconômicos mais altos. CONCLUSÃO: Concluiu-se que existem desigualdades socioeconômicas no tabagismo e sugerem-se políticas de controle tanto na iniciação e cessação focadas em grupos desfavorecidos economicamente OBJECTIVES: To test the association of the prevalence of current smoking, cigarrete consumption smoking initiation, age of onset and cessation of smoking in Brazil with the socioeconomic conditions of the population. METHODS: This is a national survey conducted in 2008 with 39,425 men and women. The sampling was used in four stages. We estimated the prevalence rates of initiation and cessation of smoking, number of cigarettes manufactured and age of onset sex-adjusted according to the explanatory variables. We calculated prevalence ratios according to skin color, per capita household income, education and place of residence by Poisson regression, adjusting for age measures. RESULTS: The results suggest socioeconomic inequalities in the prevalence, initiation, age of onset and cessation of smoking in men and women. Education level was the indicator of socioeconomic inequality with greater magnitude of effect in the studied variables, except the outcome of smoking cessation in women, there was no statistically significant association with education. The mean of cigarette consumption is higher among men and women with higher socioeconomic indicators. CONCLUSION: We concluded that there are socioeconomic inequalities in smoking and suggest policies to control both the initiation and cessation focused on economically disadvantaged groups
