Limits of tangents of quasi-ordinary hypersurfaces

We compute explicitly the limits of tangents of a quasi-ordinary singularity in terms of its special monomials. We show that the set of limits of tangents of Y is essentially a topological invariant of Y

Moduli of germs of legendrian curves

We construct the generic component of the moduli space of the germs of Legendrian curves with generic plane projection topologicaly equivalent to a curve y^n = x^m

Optimization Inspired on Herd Immunity Applied to Non-Hierarchical Grouping of Objects

Characterized as one of the most important operations related to data analysis, one non-hierarchical grouping consists of, even without having any information about the elements to be classified, establish upon a finite collection of objects, the partitioning of the items that constitute it into subsets or groups without intersecting, so that the elements that are part of a certain group are more similar to each other than the items that belong to distinct group. In this context, this study proposes the application of a meta-heuristic inspired by herd immunity to the determination of the non-hierarchical grouping of objects, and compares the results obtained by this method with the answers provided by four other grouping strategies, described in the literature. In particular, the resulting arrangements of the classification of 33 benchmark collections, performed by the suggested algorithm, by the metaheuristic inspired by the particle swarm, by the genetic algorithm, by the K-means algorithm and by the meta-heuristic inspired by the thermal annealing process, were compared under the perspective of 10 different evaluation measures, indicating that the partitions established by the meta-heuristic inspired by the herd immunity may, in certain respects, be more favorable than the classifications obtained by the other clustering methods

“Many of us are rare”: the right to health and the moral economy of rare diseases activism in Brazil (1990-2020)

This article discusses the different meanings attributed to the right to health in the mobilizations to guarantee care for rare disease patients in Brazil. Since the early 1990s, rare disease patient family associations have been putting agendas to the public authorities, with demands ranging from the recognition of diseases to the development of research and diagnostic tests. The trajectory of the mobilizations to guarantee care for rare disease patients is part of a broader process of social articulation around the possibilities and limits of the Brazilian National Health System. The right to health is at the center of this process, being the Subject of varied debates and interpretations in the political, health, and legal arenas, involving arguments guided by scientific evidence, legal principles, and moral values. We argue that these variations in the directions of the right to health have involved concomitant processes of strengthening networks of rare disease actors and institutions, and of maturing the healthcare system, both converging towards the establishment of a “moral economy of rare disease patients”. This moral economy is centered on the idea that the public health relevance of these diseases cannot be identified by epidemiological evidence, but rather by individual and family experience. We used a wide scope of documentation: texts from newspapers and magazines widely circulated in the country, legislative material, publications in specialized journals, and website materials from rare disease patient organizations in Brazil

Environmental licensing of major undertakings : possible connection between health and environmentResumo

A perspectiva de uma avaliação multidisciplinar, que considere os impactos da modificação do meio ambiente sobre a saúde da população, durante a implantação de projetos de desenvolvimento potencialmente poluidores, é incipiente no Brasil. Considerando o cenário de grandes empreendimentos no país, ampliar o olhar sobre a relação saúde-ambiente a partir dos processos sociais e econômicos de desenvolvimento, visando projetos ecologicamente sustentáveis, é uma estratégia fundamental. O artigo explora o debate sobre as relações entre o modelo de desenvolvimento vigente, os riscos, o ambiente e a saúde e discute a importância da participação do setor saúde nos processos de licenciamento ambiental, instrumento da Avaliação de Impacto Ambiental (AIA). Visando à construção de territórios mais sustentáveis, ambientalmente e socialmente, o setor saúde vem buscando oportunidades para participar dos processos de licenciamento de grandes empreendimentos, na perspectiva da AIA. Resultados de uma pesquisa realizada no âmbito do Ministério da Saúde demonstrou a forma de participação nesses processos, apontando para as potencialidades e fragilidades que favorecem ou dificultam o fortalecimento de ações preventivas em saúde pública, na implementação de grandes projetos de desenvolvimento no Brasil.The prospect of multidisciplinary assessment that considers the environmental impacts on the health of the population during the implementation of potentially polluting projects is incipient in Brazil. Considering the scenario of major undertakings in the country, broadening the outlook on the health and environment relationship based on social and economic development processes striving for environmentally sustainable projects is a key strategy. This article examines the debate on the relationship between the current development model, the risks, the environment and health and discusses the importance of the participation of the health sector in the environmental licensing procedures, which is the instrument of the Environmental Impact Assessment (EIA). Seeking to create more environmentally and socially sustainable territories, the health sector has been looking for opportunities to participate in the licensing processes of major undertakings from the EIA standpoint. Results of research conducted by the Ministry of Health have demonstrated the form of participation in these processes, highlighting the strengths and weaknesses that favor or hinder the increase of preventive actions in public health in the implementation of major undertakings in Brazil

Contributions of geography to environmental impact assessment in urban areas, based on the use of pressure state impact- response (P.S.I.R) methodology

A maior parte da população mundial vive em meio urbano, entretanto, diante da falta de organização, várias cidades no mundo têm problemas de degradação ambiental, especialmente nos países da América Latina e Caribe, onde a rápida urbanização é o principal vetor das pressões e conseqüentes impactos sofridos por essas cidades. Diante do quadro de piora da qualidade ambiental urbana, várias metodologias foram desenvolvidas para contribuir com a gestão ambiental, dentre elas a matriz P.E.I.R. (pressão-estado-impacto-resposta) desenvolvida pela Organização para Cooperação e Desenvolvimento Econômico (OCDE) que vem sendo utilizada pelo Programa das Nações Unidas para o Meio Ambiente (PNUMA) no projeto GEO Cidades. Ao lançar um olhar geográfico sobre a cidade o geógrafo tem muito a contribuir com esta metodologia, por seu objeto de estudo ser justamente o espaço geográfico, ou seja, aquele construído e continuamente transformado pelo homem ao longo do tempo. O objetivo desse artigo é mostrar como o geógrafo, ao fazer a análise da interação do homem com o meio, pode contribuir com os estudos através da matriz PEIR.Most part of the world population live in a urban environment, although with the lack of organization, several cities in the world have environmental problems, specially in the Latin America and Caribbean countries where the fast urbanization is the mainly cause of the pressure and its impacts in those cities. Based upon the diagnosis of an aggravation of environmental quality in the cities, many methodologies have been developed in a way to contribute to the environmental management, among then the PSIR matrix (pressure-state-impact-response) designed by the Organization for Economic Cooperation and Development (OECD), which UNEP (United Nations Environment Programme) has been using in the GEO Cities Project. The geographic point of view of the city has a lot to offer to the optimization of the results of such methodology. This argument is plausible because geographical studies, consider the broad aspects of the space in which human societies develop their ever changing activities through time. The aim of this paper is to show how the geographer, with the analysis of man's interaction with the environment, can contribute to studies by the PSIR matrix
