  1. Massa do gás e das estrelas em aglomerados: eficiência da formação estelar

    NASA Astrophysics Data System (ADS)

    Laganá, T. F.; Lima Neto, G. B.

    2003-08-01

    Os aglomerados de galáxias apresentam um interesse especial para a cosmologia observacional. Eles são as maiores estruturas ligadas pela gravitação no Universo e relaxadas na região central. A comparação entre a massa do gás intra-aglomerado (responsável por ~25% da massa total, inferida a partir de observações em raios-X), a massa contida nas estrelas (i.e., nas galáxias) e a massa total (incluindo a matéria escura não bariônica), nos dá informações importantes sobre os processos de formação e evolução de aglomerados. Por exemplo, a razão entre a massa do gás e a massa total é uma medida da fração de bárions no Universo (razão entre a matéria bariônica e matéria escura) e, utilizando a densidade de bárions predita pela nucleosíntese primordial, podemos deduzir a densidade de matéria escura no Universo (cf. White et al. 1993). O objetivo deste trabalho é obter as razões entre as massas do gás, estelar (contida nas galáxias), e a total (massa dinâmica). As massas do gás e total são obtidas a partir das análises fotométrica e espectroscópica em raios-X enquanto que a massa estelar é obtida pela análise fotométrica das galáxias. Esta análise foi aplicada ao aglomerado Abell 496 observado pelo satélite XMM-Newton. A massa contida nas galáxias foi estimada a partir da função de luminosidade obtida por Durret et al. (2002). Para determinar as massas dinâmica e do gás nos precisamos determinar os perfis radiais de densidade e temperatura. Nós apresentaremos aqui estes resultados e suas implicações na eficiência da formação estelar em Abell 496.

  2. Rotação do jato em DG tau próximo à região de sua formação: análise comparativa das velocidades radiais simuladas e observadas

    NASA Astrophysics Data System (ADS)

    Cerqueira, A. H.; de Gouveia dal Pino, E. M.

    2003-08-01

    Os modelos magneto-centrífugos utilizados para explicar a formação dos jatos Herbig-Haro assumem a presença de um disco de acresção em rotação kepleriana na base de lançamento do jato. Neste cenário, o jato transmite a informação da rotação do disco para regiões distantes da fonte central, além da superfície de Alfvén, na região de colimação inicial do jato. Recentemente, Bacciotti et al. (2002, ApJ, 537, L49) obtiveram pela primeira vez uma evidência observacional de rotação em um jato HH, o jato em DG Tau, em regiões próximas da fonte central, compatível (qualitativa e quantitativamente) com o esperado a partir dos modelos magneto-centrífugos para a produção e colimação inicial de jatos HH. No presente trabalho, apresentamos mapas de velocidade radial, obtidos através de simulações numéricas tri-dimensionais SPH, para um jato com características semelhantes ao jato em DG Tau, objetivando uma comparação com os mapas de velocidade radiais obtidos por Bacciotti et al.. Nossos resultados, embora preliminares, indicam que a inclusão de efeitos como a precessão, evidenciada em DG Tau (Dougados et al. 2000, A&A, 357, L61) devem ser levadas em consideração na análise da presença de rotação não só em DG Tau mas em qualquer sistema, com o uso das velocidades radias observadas. A ausência de um grau elevado de simetria axial (quebrada, por exemplo, pela precessão do eixo do jato; ou pela presença de uma superfície interna de trabalho, ou seja, um bow shock interno), implica também em uma maior complexidade nos mapas, com conseqüências relevantes para suas interpretações.

    Forty students, at ages between 14 and 18 years old, from three schools in Bauru city, were questioned about their alternative conceptions concerning the phenomenon of formation of the Moon Phases. It was observed that some of the pupils confound the phenomenon of the formation of the Moon Phases with the phenomenon of the formation of the lunar eclipses, others are unaware of the reason of the phenomenon, they present incoherent alternative conceptions of the reality or incomplete conceptions. The results found here are aimed at the teachers of Elementary Education and can be used as a subsidy for future development of new pedagogical methods. Cuarenta estudiantes, con edad entre 14 y 18 años, pertenecientes a tres escuelas de la ciudad de Bauru, fueron cuestionados sobre sus concepciones alternativas acerca del fenómeno de la formación de las fases de la Luna. Fue observado que algunos alumnos confunden el fenómeno de formación de las fases de la Luna con el fenómeno de formación de los eclipses lunares, otros desconocen el motivo delfenómeno, presentan concepciones alternativas incoherentes con la realidad o bien presentan concepciones incompletas. Los resultados aquí encontrados son destinados a los profesores de la Enseñanza Básica y podrán ser usados como ayuda para el futuro desarrollo de nuevos métodos pedagógicos.

  4. Ambiente e formação estelar em galáxias

    NASA Astrophysics Data System (ADS)

    Mateus, A., Jr.; Sodré, L., Jr.

    2003-08-01

    Estudamos o ambiente de galáxias com formação estelar inicialmente a partir de uma amostra limitada em volume proveniente do 2dF Galaxy Redshift Survey. Discriminamos as galáxias com formação estelar com base em distintas classes espectrais, utilizando para esta classificação as larguras equivalentes das linhas [OII]l3727 e Hd. O ambiente é caracterizado pela densidade espacial local de galáxias. Mostramos que a fração de galáxias com formação estelar é bastante reduzida em ambientes densos, enquanto a de galáxias passivas aumenta nestas regiões. Por outro lado, quando analisamos a fração de galáxias que apresentam um surto recente de formação estelar, notamos que ela independe do ambiente, sendo que em regiões mais densas alguns destes objetos apresentam distorções em sua morfologia. Estes resultados são confrontados com a análise da dependência ambiental da taxa de formação estelar, estimada pela emissão em Ha, de uma amostra extraída do Sloan Digital Sky Survey. Um declínio gradual da formação estelar também é observado nesta análise, sugerindo que as interações por efeitos de maré sejam responsáveis pela redução da formação estelar em ambientes densos através da remoção do reservatório de gás das galáxias. No entanto, estas interações também podem induzir surtos de formação estelar nas galáxias, além de peculiaridades morfológicas observadas nos objetos que habitam regiões mais densas.

    NASA Astrophysics Data System (ADS)

    Kirchner, Stefan

    Im Jahre 1953 wurde von James Watson und Francis Crick erstmalig der strukturelle Aufbau der sogenannten DNA (Desoxyribonukleinsäure) beschrieben, welche das Erbgut jedes Lebewesens enthält. Der wesentliche Teil des Erbguts wird dabei durch eine sehr lange Folge der vier Basen Adenin (A), Cytosin (C), Guanin (G) und Thymin (T) codiert. Seit einigen Jahren ist es möglich, die Folge der vier Basen zu einer gegebenen DNA zu bestimmen. Biologen bezeichnen diesen Vorgang als Sequenzierung.

  13. A eficiência de formação estelar em Musca

    NASA Astrophysics Data System (ADS)

    Hickel, G. R.; Vilas-Boas, J. W. S.; Roberto, A. J.., Jr.; Khan, R. P.

    2003-08-01

    Apresentamos os resultados de um survey no infravermelho próximo (bandas J e H), executado no Laboratório Nacional de Astrofísica, na direção da nuvem escura em forma de filamento de Musca (observamos ao longo de todo o filamento, além de todas as fontes pontuais IRAS e/ou fontes ROSAT brilhantes a uma distância de 2o da nuvem). Nosso objetivo é determinar a eficiência de formação estelar para esta nuvem escura (massa de estrelas formadas/massa da nuvem), procurando por objetos estelares jovens de pequena massa no seu interior e/ou evoluídos o suficiente para estarem afastados do local de nascimento, mas ainda mostrando características de objetos pré-seqüência principal como emissão de raios-X e excesso de emissão no infravermelho próximo. Este survey não estabeleceu nenhum viés na seleção de fontes pontuais IRAS ou fontes ROSAT, uma vez que a imensa maioria das fontes pontuais IRAS nesta região têm qualidade de fluxo ruim. Os candidatos a objetos estelares jovens foram selecionados pelo excesso no índice de cor (J-H), descontados os efeitos da extinção interestelar na linha de visada, determinada através da emissão estendida no infravermelho distante (IRAS). Estimativas de massa foram feitas para estes candidatos, através da relação massa-luminosidade, para calcular a eficiência de formação estelar de Musca.

  17. DAS Writeback: A Collaborative Annotation System

    PubMed Central

    2011-01-01

    Background Centralised resources such as GenBank and UniProt are perfect examples of the major international efforts that have been made to integrate and share biological information. However, additional data that adds value to these resources needs a simple and rapid route to public access. The Distributed Annotation System (DAS) provides an adequate environment to integrate genomic and proteomic information from multiple sources, making this information accessible to the community. DAS offers a way to distribute and access information but it does not provide domain experts with the mechanisms to participate in the curation process of the available biological entities and their annotations. Results We designed and developed a Collaborative Annotation System for proteins called DAS Writeback. DAS writeback is a protocol extension of DAS to provide the functionalities of adding, editing and deleting annotations. We implemented this new specification as extensions of both a DAS server and a DAS client. The architecture was designed with the involvement of the DAS community and it was improved after performing usability experiments emulating a real annotation task. Conclusions We demonstrate that DAS Writeback is effective, usable and will provide the appropriate environment for the creation and evolution of community protein annotation. PMID:21569281

    ómicos y la estructura espacial del montaje del Universo son características fundamentales. Muchos indican Sol y estrellas como cosas distintas: el Sol es un objeto caliente y las estrellas son frías. Esos resultados nos preocupan y ciertamente señalan una urgencia de programas de formación continuada para profesores en el contenido de astronomía, pues los PCN's (Parámetros Curriculares Nacionales) recomiendan con énfasis la enseñanza de este contenido. O modo de pensar dos professores de Ciências do ensino fundamental sobre os elementos da Astronomia é o objeto de pesquisa presente neste artigo, cuja metodologia consiste em entrevistas semiestruturadas, filmadas em vídeo e centradas numa perspectiva tridimensional dos elementos astronômicos, possibilitando um mapeamento das concepções das formas e das dimensões da Terra, do Sol, da Lua, dos planetas e das estrelas, bem como da concepção de céu e de Universo como um todo. Os resultados indicam um Universo contendo: Sol, estrelas, planetas e Lua, onde o Sistema Solar é parte do todo. Algumas vezes o Universo é concebido como o próprio Sistema Solar. Os objetos estão no céu ou no Universo o qual, para muitos, se restringe ao espaço que está acima da Terra. A forma plana dos objetos astronômicos e a estrutura espacial da montagem do Universo são características marcantes. Muitos indicam Sol e estrelas como coisas diferentes: Sol é um objeto quente e as estrelas são frias. Esses resultados nos preocupam e certamente sinalizam uma urgência de programas de formação continuada para professores no conteúdo de astronomia, uma vez que os PCN's indicam fortemente o ensino desse conteúdo.

  12. Moisture Forecast Bias Correction in GEOS DAS

    NASA Technical Reports Server (NTRS)

    Dee, D.

    1999-01-01

    Data assimilation methods rely on numerous assumptions about the errors involved in measuring and forecasting atmospheric fields. One of the more disturbing of these is that short-term model forecasts are assumed to be unbiased. In case of atmospheric moisture, for example, observational evidence shows that the systematic component of errors in forecasts and analyses is often of the same order of magnitude as the random component. we have implemented a sequential algorithm for estimating forecast moisture bias from rawinsonde data in the Goddard Earth Observing System Data Assimilation System (GEOS DAS). The algorithm is designed to remove the systematic component of analysis errors and can be easily incorporated in an existing statistical data assimilation system. We will present results of initial experiments that show a significant reduction of bias in the GEOS DAS moisture analyses.

    2003-08-01

    Neste trabalho, combinamos observações de polarização linear no óptico (banda R), dados no infravermelho distante (IRAS) e observações de transições moleculares em radiofreqüências (CO e espécies isotópicas, HCN e HCO+) para analisar o glóbulo cometário (GC) CG30 (na região da IRAS Vela Shell), que apresenta objetos Herbig-Haro e ejeções de matéria, além de uma fonte pontual IRAS em seu interior. Os objetivos deste estudo são: determinar a eficiência de formação estelar nos glóbulos cometários, através da relação entre a massa total do GC e da massa das estrelas em formação; determinar como o campo magnético influencia na formação de estrelas no interior destes objetos; e analisar as modificações que ejeções de matéria de estrelas em formação causam no gás e no campo magnético dos GCs. Combinando nossos dados com trabalhos já publicados, mostramos que CG30 tem uma eficiência de formação estelar em torno de 3%; que o campo magnético é importante na manutenção da estrutura global do GC e demonstra sinais de torção e compressão; e que a ejeção bipolar de matéria das estrelas do par formam uma ejeção quadripolar, a qual influencia na densidade e temperatura do gás e no grau de polarização dos grãos de poeira associados ao gás do GC.

  16. Development of a standardised pro forma for specialist palliative care multidisciplinary team meetings.

    PubMed

    Gallagher, Jennifer; Forman, Margaret Louise

    2012-05-01

    A pro forma of the caseload of the community palliative care clinical nurse specialists in the Central Lancashire Community Specialist Palliative Care Team was devised to provide a brief overview of each patient's plan of care for use in the multidisciplinary team meetings and as a consequence of preparing for the UK Department of Health's peer review process. The pro forma was also designed to be used in everyday clinical practice in Gold Standards Framework meetings in the community. It has been evaluated by the team and found to be helpful for highlighting key issues in clinical practice, such as symptoms, psychological and emotional needs, and Preferred Priorities of Care. Over the past 2 years, it has also complemented the organisation's drive to become 'paperless'. This article looks at how the pro forma was developed, how it has evolved over time, and how it works today. Consideration has also been given to its benefits and limitations.

    1976-01-01

    Techniques are presented for the solution of structural dynamic systems on an electronic digital computer using FORMA (FORTRAN Matrix Analysis). FORMA is a library of subroutines coded in FORTRAN 4 for the efficient solution of structural dynamics problems. These subroutines are in the form of building blocks that can be put together to solve a large variety of structural dynamics problems. The obvious advantage of the building block approach is that programming and checkout time are limited to that required for putting the blocks together in the proper order.

  18. "Das Konkrete ist das Abstrakte, an das man sich schließlich gewöhnt hat." (Laurent Schwartz) Über den Ablauf des mathematischen Verstehens

    NASA Astrophysics Data System (ADS)

    Lowsky, Martin

    Die im Titel genannte Aussage findet sich in den Lebenserinnerungen von Laurent Schwartz (1915-2002), einem der fruchtbarsten Mathematiker, Mitglied der Gruppe Bourbaki. Im Original lautet die Aussage: "un objet concret est un objet abstrait auquel on a fini par s'habituer." Schwartz erläutert sie am Beispiel des Integrals über {e^{-1/2{x^2}}} , das den Wert Wurzel aus 2π hat und in dem sich also die Zahlen e und π verknüpfen. Was Schwartz aber vor allem ausdrücken will, ist dies: Das mathematische Verständnisd geht langsam vor sich und es bedarf der Anstrengung. "Es ist eine Frage der Zeit und der Energie", sagt Schwartz, und gerade dies mache es so schwer, die höhere Mathematik unter das Volk zu bringen.

    At our institution, a large tertiary referral centre for vascular surgery, patients are often admitted directly to the ward and clerked by foundation year one (FY1) doctors. We found that these clerkings frequently fell short of national record keeping standards, potentially leading to an increased risk for patients during their hospital stay. In addition, we found that junior doctors did not feel confident in clerking vascular surgery patients. A literature review found that high quality clerkings were strongly linked to improved patient safety, and that the use of a pro forma was one method to improve compliance with documentation guidelines. We devised a clerking pro forma based on national guidelines and introduced it to the department. We found that the use of a pro forma significantly improved documentation standards across a number of domains, including patient demographics, presenting complaint, and family and social histories (p <0.05). Examinations were significantly more comprehensive, with cardiac and vascular examination as well as peripheral pulses documented (p <0.05). In conclusion, we found that using a pro forma helped to aid junior doctors in clerking new patients, and significantly improved the quality of their history and examinations. This leads to a potential positive impact on patient safety during their inpatient stay, and should be rolled out more widely across the hospital. PMID:27418964

  4. Twenty‐eight‐joint counts invalidate the DAS28 remission definition owing to the omission of the lower extremity joints: a comparison with the original DAS remission

    Objective To compare 28 joint disease activity score (DAS28) remission with comprehensive joint count DAS remission in rheumatoid arthritis. Methods 620 actually measured paired observations of DAS28 and DAS were analysed in 155 patients. Discordant observations (either DAS or DAS28 below remission cut off level: 1.6 for DAS and 2.6 for DAS28) and concordant observations (both DAS and DAS28 below their remission cut off level) were analysed separately. Results 91 of 620 paired DAS observations (15%) were discordant; 87 (in 53 patients) comprised observations in which the DAS28 remission criterion, but not the DAS remission criterion, was met. The reverse was found in only four observations, which were therefore omitted. With the original DAS as standard, DAS28 sensitivity was 95% and specificity 84%. Probability plots showed a swollen joint count >0 in 75% of discordant pairs v 48% of concordant pairs. The same was found for total joint count (TJC >0 in 90% v 40%; median TJC, 0 v 6) and patient global assessment, but not for ESR. Individual joint analysis showed that 51% of discordant v 18% of concordant observations (p<0.0005) had involvement of lower extremity joints that are not included in the DAS28. Conclusions DAS remission is more conservative than DAS28 remission. Activity (tenderness and swelling) in joints not included in the reduced joint counts (ankles, feet) mainly account for the discrepancy between the two assessments. DAS28 remission at a cut off level of 2.6 has insufficient construct validity and should be used with caution in clinical practice and clinical trials. PMID:16219709

    The Data Access System (DAS) is a and data management software system, providing a reusable solution for the storage of data acquired both from telescopes and auxiliary data sources during the instrument development phases and operations. It is part of the Customizable Instrument WorkStation system (CIWS-FW), a framework for the storage, processing and quick-look at the data acquired from scientific instruments. The DAS provides a data access layer mainly targeted to software applications: quick-look displays, pre-processing pipelines and scientific workflows. It is logically organized in three main components: an intuitive and compact Data Definition Language (DAS DDL) in XML format, aimed for user-defined data types; an Application Programming Interface (DAS API), automatically adding classes and methods supporting the DDL data types, and providing an object-oriented query language; a data management component, which maps the metadata of the DDL data types in a relational Data Base Management System (DBMS), and stores the data in a shared (network) file system. With the DAS DDL, developers define the data model for a particular project, specifying for each data type the metadata attributes, the data format and layout (if applicable), and named references to related or aggregated data types. Together with the DDL user-defined data types, the DAS API acts as the only interface to store, query and retrieve the metadata and data in the DAS system, providing both an abstract interface and a data model specific one in C, C++ and Python. The mapping of metadata in the back-end database is automatic and supports several relational DBMSs, including MySQL, Oracle and PostgreSQL.

    2011-03-01

    The paper presents a new approach for a bachelor-level curriculum structure in engineering. The approach is called DAS formalism according to its three phases: description, analysis and synthesis. Although developed specifically for process and environmental engineering, DAS formalism has a generic nature and it could also be used in other engineering fields. The motivation for this new curriculum structure originates from the urge to solve the problems that engineering education has faced during the past decades, e.g. student recruitment problems and dissatisfactory learning outcomes. The focus of this paper is on the structure of the curriculum but the content is also discussed when it has an effect on the structure and its implementation. The presented structure, i.e. DAS formalism, builds upon the ideas of some classical pedagogical theories, which have regularly been applied at course level but seldom used to solve curriculum-level issues.

    The genetic relatedness of five formae speciales of Fusarium oxysporum causing wilts of cucurbit plants was determined by DNA fingerprinting with the moderately repetitive DNA sequences FOLR1 to FOLR4. The four FOLR clones were chosen from a genomic library made from F. oxysporum f. sp. lagenariae 03-05118. Total DNAs from 50 strains representing five cucurbit-infecting formae speciales, cucumerinum, melonis, lagenariae, niveum, and momordicae, and 6 strains of formae speciales pathogenic to other plants were digested with EcoRV and hybridized with 32P-labeled FOLR probes. The strains were clearly distinguishable at the formae specialis level on the basis of FOLR DNA fingerprints. Fifty-two fingerprint types were detected among the 56 strains by using all FOLR probes. These probes were used to infer phylogenetic relationships among the DNA fingerprint types by the unweighted pair group method using averages and parsimony analysis. The fingerprint types detected in each of the formae speciales cucumerinum, lagenariae, niveum, and momordicae were grouped into a single cluster. However, two different genetic groups occurred in the formae specialis melonis. The two groups also differed in pathogenicity: one group caused wilts of muskmelon and oriental melon, while the second was pathogenic only to muskmelon. The fingerprint types of different formae speciales pathogenic to plants other than cucurbits were distinguishable from one another and from the fingerprints of the cucurbit-infecting strains. These results suggest that the cucurbit-infecting formae speciales are intraspecific variants distinguishable at the DNA level and in their host range. Images PMID:8085813

  8. The development of the disease activity score (DAS) and the disease activity score using 28 joint counts (DAS28).

    PubMed

    2014-01-01

    In rheumatoid arthritis, disease activity cannot be measured using a single variable. The Disease Activity Score (DAS) has been developed as a quantitative index to be able to measure, study and manage disease activity in RA in daily clinical practice, clinical trials, and long term observational studies. The DAS is a continuous measure of RA disease activity that combines information from swollen joints, tender joints, acute phase response and patient self-report of general health. Cut points were developed to classify patients in remission, as well as low, moderate, and severe disease activity in the 1990s. DAS-based EULAR response criteria were primarily developed to be used in clinical trials to classify individual patients as non-, moderate, or good responders, depending on the magnitude of change and absolute level of disease activity at the conclusion of the test.

  9. Host perception of jasmonates promotes infection by Fusarium oxysporum formae speciales that produce isoleucine- and leucine-conjugated jasmonates

    Summary Three pathogenic forms, or formae speciales, of Fusarium oxysporum infect the roots of Arabidopsis thaliana belowground, instigating symptoms of wilt disease in leaves aboveground. In prior reports, Arabidopsis mutants that are deficient in the biosynthesis of abscisic acid or salicylic acid or insensitive to ethylene or jasmonates exhibit more or less wilt disease than wild type, implicating the involvement of hormones in the normal host response to F. oxysporum. Our analysis of hormone-related mutants finds no evidence that endogenous hormones contribute to infection in roots. Mutants that are deficient in abscisic acid and insensitive to ethylene have no less infection than wild type, though they exhibit less disease. Whether a mutant that is insensitive to jasmonates affects infection depends on which forma specialis is infecting roots. Insensitivity to jasmonates suppresses infection by F. oxysporum forma specialis conglutinans and F. oxysporum forma specialis matthioli, which produce isoleucine- and leucine-conjugated jasmonate (JA-Ile/Leu) in culture filtrates; whereas, insensitivity to jasmonates has no effect on infection by F. oxysporum forma specialis raphani, which produces no detectable JA-Ile/Leu. Furthermore, insensitivity to jasmonates has no effect on wilt disease of tomato, and the tomato pathogen F. oxysporum forma specialis lycopersici produces no detectable jasmonates. Thus, some but not all F. oxysporum pathogens appear to utilize jasmonates as effectors, promoting infection in roots and/or development of symptoms in shoots. Only when infection of roots is promoted by jasmonates is wilt disease enhanced in a mutant deficient in salicylic acid biosynthesis. PMID:24387225

    Having produced the embryos of cactus Copiapoa tenuissima Ritt. forma monstruosa at the globular stage and callus, we investigated the effect of abscisic acid (ABA) in the following concentrations: 0, 0.1, 1, 10, and 100  μ M on successive stages of direct (DSE) and indirect somatic embryogenesis (ISE). In the indirect somatic embryogenesis process we also investigated a combined effect of ABA (0, 0.1, 1  μ M) and sucrose (1, 3, 5%). The results showed that a low concentration of ABA (0-1  μ M) stimulates the elongation of embryos at the globular stage and the number of correct embryos in direct somatic embryogenesis, while a high ABA concentration (10-100  μ M) results in growth inhibition and turgor pressure loss of somatic embryos. The indirect somatic embryogenesis study in this cactus suggests that lower ABA concentrations enhance the increase in calli fresh weight, while a high concentration of 10  μ M ABA or more changes calli color and decreases its proliferation rate. However, in the case of indirect somatic embryogenesis, ABA had no effect on the number of somatic embryos and their maturation. Nevertheless, we found a positive effect of sucrose concentration for both the number of somatic embryos and the increase in calli fresh weight.

    Objectives To investigate whether a difference exists between DAS28 from CRP and DAS28 from ESR in patients with rheumatoid arthritis (RA) and secondary Sjögren's syndrome (sSS). Material and methods One group comprised patients with RA and sSS, the control group comprised patients with RA. The inclusion criteria for the RA and sSS group have been specified as follows: presence of at least one symptom of dryness, and also presence of anti-SS-A and anti-SS-B or at least focus score of one in biopsy. Results The disease activity score 28 (DAS28) was assessed using both ESR and CRP in 60 patients with RA and sSS and 59 patients with RA alone. However, concordance between these two methods was good (Cohen's κ coefficient κ = 0.60, 95% CI: 0.45-0.75 in the first group and κ = 0.71, 95% CI: 0.56-0.86 in the control group). In the group with RA and sSS, the mean value of DAS28-ESR = 5.2, whereas the mean value of DAS28-CRP = 4.7 (p < 0.0001). In the group with RA alone, mean DAS28-ESR = 4.7 while mean DAS28-CRP = 4.6; no significant difference was identified. Moreover, in RA patients with sSS, mean ESR = 39 mm/h compared with mean CRP at 25 mg/l. 79% of all patients demonstrated dysproteinaemia. There were connections between higher ESR and dysproteinaemia. In the control group there was no statistically significant difference between CRP and ESR. Conclusions Both DAS28-ESR and DAS28-CRP are useful outcome measures in RA. However, in patients with RA and sSS, DAS28 should be evaluated based on CRP. PMID:27536205

    Discutimos nossa participação em um curso de treinamento para professores de diversas disciplinas do ensino médio. Nossa preocupação básica foi desenvolver instrumentos educacionais adequados para levar à sala de aula, nesse nível de ensino, de forma contextualizada, questionamentos freqüentes dos alunos sobre astronomia e sua relação com tecnologia e sociedade. Encaminhamos questões como: a evolução da astronomia, suas relações com outros ramos do conhecimento humano e conseqüentes aplicações; avanços na tecnologia dos instrumentos ópticos versus a importância da observação do céu a olho nu; a relação entre olho humano, luneta e telescópio; e desenvolvimento da tecnologia espacial e sua influência em nosso cotidiano. Objetivamos com isto fazer um resgate histórico e pedagógico das aplicações e observações do céu no cenário escolar, destacando a relação entre eventos astronômicos, olho humano, instrumentos mediadores e suas contextualizações históricas e sociais. Produtos desta abordagem foram o desenvolvimento e a adaptação de práticas e materiais instrucionais diversos (e.g., "espelhos" de isopor e "raios luminosos" de bolinhas de gude; montagens envolvendo velas, lasers, lentes e espelhos; desmonte e análise de peças de um telescópio; etc.). Além disto, como outro resultado deste trabalho, elaboramos textos sobre história da astronomia e da óptica para atividades em classe. Com estas ações visamos facilitar a concretização de conceitos físicos envolvidos, exemplificar um ensino contextualizado e interdisciplinar motivado por temas astronômicos e favorecer que práticas e discussões feitas com os treinandos possam ser transpostas para a sala de aula. A reação dos professores às práticas propostas foi bastante positiva. Todos esses aspectos são discutidos em detalhe neste trabalho. (PPGECNM/UFRN; PRONEX/FINEP; NUPA/USP; Temáticos/FAPESP)

    Hochwasser ist ein natürliches Ereignis: Seit jeher sind die Menschen mit Hochwasser und seinen Auswirkungen konfrontiert. Das Ausmaß von Hochwasser reicht dabei von Straßenüberschwemmungen bis zur Überflutung ganzer Landesteile. Auch im Oderflußsystem waren und sind Überschwemmungen keine Seltenheit, in den letzten 200 Jahren ereigneten sie sich in den Jahren 1813, 1838, 1854, 1870, 1903, 1958, 1965, 1970, 1972, 1977, 1981, 1985 und 1997. Das Hochwasser von 1997 war jedoch das schwerste im genannten Zeitraum. Als Reaktion auf das Hochwasser von 1997 wurde in der betroffenen Region das Programm 〝Oder 2006`` entwickelt. Mit seiner Hilfe sollen die Auswirkungen künftiger Hochwasserereignisse abgeschwächt werden.

    We report on the impact of revisions made to an existing pro forma facilitating routine assessment and the management of paediatric HIV and tuberculosis (TB) in KwaZulu-Natal, South Africa. An initial documentation audit in 2010 assessed 25 sets of case notes for the documentation of 16 select indicators based on national HIV and TB guidelines. Using the findings of this initial audit, the existing case note pro forma was revised. The introduction of the revised pro forma was accompanied by training and a similar repeat audit was undertaken in 2012. This demonstrated an overall improvement in documentation. The three indicators that improved most were documentation of maternal HIV status, child's HIV status and child's TB risk assessment (all P < 0.001). This study suggests that tailor-made documentation pro formas may have an important role to play in improving record keeping in low-resource settings. PMID:24311547

    Although Fursarium oxysporum causes diseases in economically important plant hosts, identification of F. oxysporum formae speciales has been difficult due to confusing phenotypic classification systems. To resolve these complexity, we evaluated genetic relationship of nine formae speciales of F. oxysporum with random amplified polymorphic DNA (RAPD), amplified fragment length polymorphism (AFLP), and translation elongation factor-1 alpha (EF-1α) gene. In addition, the correlation between mycotoxin content of fusaric acid and isolates based on molecular marker data was evaluated using the modified Mantel's test. According to these result, these fusaric acid-producing strains could not identify clearly, and independent of geographic locations and host specificities. However, in the identification of F. oxysporum formae speciales, especially, AFLP analysis showed a higher discriminatory power than that of a the RAPD and EF-1α analyses, all three techniques were able to detect genetic variability among F. oxysporum formae speciales in this study.

    Biological tissue-derived biomaterials must be chemically modified to avoid immediate degradation and immune response before being implanted in human body to replace malfunctioning organs. DAS with active aldehyde groups was employed to replace glutaraldehyde (GA), a most common synthetic crosslinking reagent in clinical practice, to fix bioprostheses for lower cytotoxicity. The aim of this research was to evaluate fixation effect of DAS. The tensile strength, crosslinking stability, cytotoxicity especially the anti-calcification capability of DAS-fixed tissues were investigated. The tensile strength and resistance to enzymatic degradation of samples were increased after DAS fixation, the values maintained stably in D-Hanks solution for several days. Meanwhile, ultrastructure of samples preserved well and the anti-calcification capability of samples were improved, the amount of positive staining points in the whole visual field of 15% DAS-fixed samples was only 0.576 times to GA-fixed ones. Moreover, both unreacted DAS and its hydrolytic products were nontoxic in cytotoxicity study. The results demonstrated DAS might be an effective crosslinking reagent to fix biological tissue-derived biomaterials in tissue engineering. PMID:26038106

Particularmente são importantes no mecanismo de aquecimento da coroa solar; em ventos estelares; em jatos galácticos e extragalácticos; em discos protoestelares, etc. A formulação para diferenças finitas no domínio do tempo (FDTD), aplicada a plasma magnetizado é desenvolvida para estudo das propriedades de ondas Alfvén em três dimensões (3D-FDTD). O método é aplicado inicialmente a um plasma homogêneo e isotérmico imerso em uma região com campo magnético externo B0, que sofre uma pequena perturbação. Uma vez gerada a onda, esta perturbação é retirada e, então analisamos a evolução temporal das ondas, bem como a forma de seu amortecimento.

    DAS-81910-7 cotton is a transgenic event that was transformed to contain the aad-12 and pat genes. These genes code for the AAD-12 and PAT proteins, which confer tolerance to the herbicides 2,4-D and glufosinate, respectively. Crop composition studies were conducted with DAS-81910-7 cotton (both nonsprayed and sprayed with 2,4-D and glufosinate) to comply with requirements of regulatory authorities responsible for evaluating crop safety. Results indicate compositional equivalence between DAS-81910-7 cottonseed and nontransgenic cottonseed and between sprayed and nonsprayed DAS-81910-7 cottonseed. This study builds on the results from many prior studies which support the conclusion that transgenesis is less likely to unexpectedly alter the composition of crops as compared with traditional breeding.

    The majority of patients with non-hospital pneumonia (NHP) on background of antibioticotherapy had changes of a microbiocenosis of their intestines. The article presents obtained results on the assessment of Bifi-forma probiotic use for 63 children aged from 1 month till 3 years. It has been shown that course of the pneumonia has been associated clinically with dyspepsic pain syndromes and with significant changes of intestine biocenosis by quantity reduction of bifido--and lactobacteria, decrease in escherichia having enzymatic activity and increase in hemolytic escherichia, yeastlike mushrooms, staphylococcus and other representatives of opportunistic flora. Application of this probiotic in a complex therapy on non-hospital pneumonia has shown high clinical and microbiological efficiency that allows recommending its administration to children of early age, patients with non-hospital pneumonia.

    The World Health Organization's Disability Assessment Scale II (WHO-DAS II) is a generic health-status instrument that provides six domain scores and a total, aggregate score. Two of the domain scores, communication and participation, and the total score, have good validity, internal-consistency reliability, and test-retest stability in individuals with adult-onset hearing loss. As such, these two domain scores and the total WHO-DAS II score may be useful as generic outcome measures to assess the effectiveness of hearing aid intervention for this population. Before the use of the WHO-DAS II in hearing aid clinical trials, however, the responsiveness of the instrument and the short- and long-term outcomes to hearing aid intervention had to be determined. Responsiveness and outcomes were assessed in 380 veterans (approximately half received hearing aids and half served as controls) by examining group differences, effect-size estimates, and individual differences as a function of hearing aid intervention. For comparison, data also were obtained on two disease-specific measures, the APHAB and the HHIE. The WHO-DAS II communication domain and total scores were sufficiently responsive to hearing aid intervention for use in future studies in which group differences are to be detected. The WHO-DAS II participation domain was not sufficiently responsive to hearing aid intervention. The APHAB and HHIE, both disease-specific measures, were more sensitive to hearing aid intervention than the generic measure. The short- and long-term outcomes of hearing aid intervention were also examined in the present study. Group outcomes for hearing aid intervention can be expected to be stable for at least 6 months when measured by WHO-DAS II total score and for at least 12 months when measured by the WHO-DAS II communication domain scores. Effect-size estimates and examination of the number of individuals exhibiting change scores exceeding 90% critical differences for true changes in

    2002-12-01

    The 25th birthday of ESO, in 1987, was celebrated by the publication of an illustrated popular book, "Exploring the Southern Sky" (Springer-Verlag 1987), which also saw editions in Danish, English, French, German, and Spanish. Written and illustrated by the ESO staff members Svend Laustsen, Claus Madsen and Richard M. West, its many pictures were mainly taken with the ESO 3.6m and Schmidt telescopes. The structure of the book - perhaps at that time somewhat unusual - started with things far away (Universe and galaxies), zoomed in to the Milky Way, and finally reached the Solar System (with a concluding chapter dealing with the La Silla observatory). Now, with the 4 units of the Very Large Telescope in full operation, and on the occasion of ESO's 40th birthday, another jubilee book has appeared: "Geheimnisvolles Universum: Europas Astronomen entschleiern das Weltall", written by the science journalist Dirk H. Lorenzen, of Hamburg, Germany, and prefaced by Catherine Cesarsky, Director General of ESO. Presumably, this book will also soon become available in more languages spoken in ESO member countries. Thus it may be worthwhile to review the first edition, although some readers may like to wait for more easily accessible editions. Before going into details, let me first mention that I find this a very impressing book, great to look at and refreshing to read. With ESO seen through the eyes of a visitor, things gain a perspective that is quite different from that of the previous book, and at least as attractive. It comes as no surprise that the book starts with a visit of ESO's showcase, the Paranal Observatory, and the writer not only notes down his own impressions, but also cites statements of some of the many people that keep Paranal going - technicians and staff astronomers. This mixture of texts provides a good impression of the operations at a large observatory for the general reader. The two more 'astronomical' parts that follow deal with star and planet

    Lagoa das Furnas is a crater lake located in an area exposed to geohazards from earthquakes and volcanic activity on the island of São Miguel in the Azores Archipelago. Geophysical mapping of Lagoa das Furnas reveals a previously undiscovered volcanic dome. This dome is comprised largely of subaquatic pyroclastic debris of trachytic composition. Sedimentological, petrological, geochemical and geochronological studies of pyroclastic deposits from the dome link it to the historically documented "Furnas 1630" eruption. The chemistry of glass and crystal fragments sampled from the dome suggests that it is comprised of more evolved magma than that of the main Furnas 1630 dome located 1400 m away. This suggests that the dome was formed during a final phase of the 1630 eruption in the Lagoa das Furnas area.

    Die amerikanischen Wissenschaftler und ihre emigrierten Kollegen, die am Bau der Atombombe beteiligt waren, verfügten über sehr widersprüchliche und großteils falsche Informationen über den Fortschritt des deutschen Uranprogramms. Noch nach Kriegsende lässt sich dies an Aussagen des Leiters der amerikanischen Alsos-Mission, Samuel Goudsmit, festmachen. Tatsächlich war das deutsche Programm hinsichtlich seiner wissenschaftlichen Grundlagen und des Managements nicht so unterlegen, wie vielfach behauptet wurde. Aber die deutschen Behörden waren nicht in der Lage, Geld und Ressourcen in gleichem Maße in das Uranprojekt zu investieren, wie etwa in das Peenemünder Raketenprojekt.

  16. Visualization of DAS28, SDAI, and CDAI: the magic carpets of rheumatoid arthritis.

    There has been continuous debate regarding the applicability of various composite measures for the assessment of disease activity in rheumatoid arthritis (RA). In order to further dissect this issue, we numerically and graphically modeled 28-joint disease activity scale (DAS28), simplified disease activity index (SDAI), and clinical disease activity index (CDAI) by three-dimensional (3D) plotting. We wished to graphically visualize the relative contribution of various elements in the three activity indices to each other. We calculated DAS28 (3 variables), SDAI, and CDAI by the standard equations. We plotted 3D "carpets" showing all combinations of the corresponding variables yielding to DAS28 = 5.1, DAS28 = 3.2, DAS28 = 2.6, SDAI = 26, SDAI = 11, and SDAI = 3.3. We also plotted the 3D carpet for CDAI. In patients with high or moderate disease activity, erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) was not a major confounding factor when calculating DAS28 and SDAI, respectively. In contrast, ESR and CRP highly overshadowed changes in joint counts and global assessments in patients with low disease activity (LDA) or those in remission. No reliable assessment of LDA can be performed in cases where ESR >54 mm/h or CRP >20 mg/dl. Similarly, remission cannot be determined if ESR >19 mm/h or CRP >5 mg/dl. As CDAI does not include acute phase reactants, CDAI may be a useful tool even in states of remission or LDA. Our results suggest that acute phase reactants are indeed major confounding factors and should be omitted when assessing RA disease activity at least in special cases. PMID:24599677

    A number of studies have attempted to identify the factor structure of the Dysfunctional Attitude Scale (DAS). However, no studies have done so using a clinical sample of outpatients likely to generalize to the clinical trials in which the DAS is commonly used. The current investigation utilized exploratory structural equation modeling in an outpatient sample (N = 982) and found support for a one-factor solution (composed of 19 items). This solution was largely confirmed in a second outpatient sample (N = 301). Construct validity was demonstrated in correlations with measures of depression, social interaction anxiety, and symptoms of obsessive-compulsive disorder.

Data for this study were collected online and involved a nation-wide sample of 3,070 deaf/hh individuals. Results indicated strong internal reliabilities for all the subscales, and construct validity was established by demonstrating that the DAS could discriminate groups based on parental hearing status, school background, and use of self-labels. Construct validity was further demonstrated through factorial analyses, and findings resulted in a final 58-item measure. Directions for future research are discussed. PMID:21263041

    The Microbial Database for Activated Sludge (MiDAS) field guide is a freely available online resource linking the identity of abundant and process critical microorganisms in activated sludge wastewater treatment systems to available data related to their functional importance. Phenotypic properties of some of these genera are described, but most are known only from sequence data. The MiDAS taxonomy is a manual curation of the SILVA taxonomy that proposes a name for all genus-level taxa observed to be abundant by large-scale 16 S rRNA gene amplicon sequencing of full-scale activated sludge communities. The taxonomy can be used to classify unknown sequences, and the online MiDAS field guide links the identity to the available information about their morphology, diversity, physiology and distribution. The use of a common taxonomy across the field will provide a solid foundation for the study of microbial ecology of the activated sludge process and related treatment processes. The online MiDAS field guide is a collaborative workspace intended to facilitate a better understanding of the ecology of activated sludge and related treatment processes--knowledge that will be an invaluable resource for the optimal design and operation of these systems.

    2012-01-01

    Background The herbal preparation DAS-77, used for the treatment of various ailments in Nigeria, contains the milled bark of Mangifera indica L. and root of Carica papaya L. Toxicological assessment of the preparation was carried out in this study. Methods In the acute toxicity study, DAS-77 was administered to mice p.o. up to 20 g/kg in divided doses and i.p. at 250–3000 mg/kg. Mortality within 24 h was recorded. In the chronic toxicity study, rats were treated p.o. for 90 days at doses of 80, 400 (therapeutic dose, TD) and 2000 mg/kg. By 90 days, animals were sacrificed and blood samples collected for hematological and biochemical analysis. Organs were harvested for weight determination, antioxidants and histopathological assessments. Results DAS-77 did not produce any lethality administered p.o. up to 20 g/kg in divided doses but the i.p. LD50 was 1122.0 mg/kg. At TD, DAS-77 produced significant (p < 0.05) reductions in body weight, food intake and K+, and increases in ovary weight, neutrophils and HDL, which were reversible. Histopathological presentations were generally normal. Effects at the other doses were comparable to those at TD except for reversible increases in antioxidants in the liver, kidney and testes, and sperm abnormality, and reductions in liver enzymes, sperm motility and count. Conclusions Findings in this study revealed that DAS-77 is relatively safe with the potential for enhancing in vivo antioxidant activity. However, possibly reversible side-effects include electrolyte imbalance and sterility in males. PMID:22892317

    Broiler chickens are a fast growing monogastric animal commonly used to evaluate the equivalence between transgenic and non-transgenic grains as part of the human safety assessment process. While commonly viewed like other livestock feeding trials, such studies are performed with transgenic crops with input traits (that are not designed to improve nutrition) to aid regulatory authorities in evaluating safety. Studies of this type are actually more similar to toxicology studies in purpose, with sensitive endpoints like growth used to detect metabolic perturbations. DAS-68416-4 soybean expresses the aryloxyalkanoate dioxygenase-12 (AAD-12) enzyme which inactivates 2,4-diclorophenoxyacetic acid (2,4-D) and provides DAS-68416-4 soybeans tolerance to this herbicide. DAS-68416-4 also expresses the phosphinothricin acetyltransferase (PAT) enzyme from Streptomyces viridochromogenes which confers tolerance to glufosinate-ammonium herbicides. A 6-week broiler study was conducted with diets containing toasted DAS-68416-4 soybean meal (40, 36, and 32% in starter, grower and finisher diets, respectively) to evaluate nutritional wholesomeness and safety compared with conventional comparators. Toasting soybean meal is required to inactivate endogenous antinutrients making soybean suitable for consumption by monogastric animals like broiler chickens. Toasting was found to denature both the AAD-12 and PAT proteins rendering them non-detectable by enzyme linked immunosorbent assays. Broiler growth and performance parameters were measured over a 6-week period of exposure to diets containing different sources of toasted soybean meal, and results indicate that DAS-68416-4 soybean is nutritionally equivalent to non-transgenic soybean.

    Puccinia graminis causes stem rust, a serious disease of cereals and forage grasses. Important formae speciales of P. graminis and their typical hosts are P. graminis f. sp. tritici (Pg-tr) in wheat and barley, P. graminis f. sp. lolii (Pg-lo) in perennial ryegrass and tall fescue, and P. graminis f. sp. phlei-pratensis (Pg-pp) in timothy grass. Brachypodium distachyon is an emerging genetic model to study fungal disease resistance in cereals and temperate grasses. We characterized the P. graminis-Brachypodium pathosystem to evaluate its potential for investigating incompatibility and non-host resistance to P. graminis. Inoculation of eight Brachypodium inbred lines with Pg-tr, Pg-lo or Pg-pp resulted in sporulating lesions later accompanied by necrosis. Histological analysis of early infection events in one Brachypodium inbred line (Bd1-1) indicated that Pg-lo and Pg-pp were markedly more efficient than Pg-tr at establishing a biotrophic interaction. Formation of appressoria was completed (60-70% of germinated spores) by 12 h post-inoculation (hpi) under dark and wet conditions, and after 4 h of subsequent light exposure fungal penetration structures (penetration peg, substomatal vesicle and primary infection hyphae) had developed. Brachypodium Bd1-1 exhibited pre-haustorial resistance to Pg-tr, i.e. infection usually stopped at appressorial formation. By 68 hpi, only 0.3% and 0.7% of the Pg-tr urediniospores developed haustoria and colonies, respectively. In contrast, development of advanced infection structures by Pg-lo and Pg-pp was significantly more common; however, Brachypodium displayed post-haustorial resistance to these isolates. By 68 hpi the percentage of urediniospores that only develop a haustorium mother cell or haustorium in Pg-lo and Pg-pp reached 8% and 5%, respectively. The formation of colonies reached 14% and 13%, respectively. We conclude that Brachypodium is an apt grass model to study the molecular and genetic components of incompatiblity

    Background The Distributed Annotation System (DAS) is a widely used network protocol for sharing biological information. The distributed aspects of the protocol enable the use of various reference and annotation servers for connecting biological sequence data to pertinent annotations in order to depict an integrated view of the data for the final user. Results An annotation server has been devised to provide information about the endogenous retroviruses detected and annotated by a specialized in silico tool called RetroTector. We describe the procedure to implement the DAS 1.5 protocol commands necessary for constructing the DAS annotation server. We use our server to exemplify those steps. Data distribution is kept separated from visualization which is carried out by eBioX, an easy to use open source program incorporating multiple bioinformatics utilities. Some well characterized endogenous retroviruses are shown in two different DAS clients. A rapid analysis of areas free from retroviral insertions could be facilitated by our annotations. Conclusion The DAS protocol has shown to be advantageous in the distribution of endogenous retrovirus data. The distributed nature of the protocol is also found to aid in combining annotation and visualization along a genome in order to enhance the understanding of ERV contribution to its evolution. Reference and annotation servers are conjointly used by eBioX to provide visualization of ERV annotations as well as other data sources.

    Radio on fiber (RoF) - distributed antenna system (DAS) over wavelength division multiplexing - passive optical network (WDM-PON) with multiple - input multiple - output (MIMO) has been proposed as a next generation radio access network (RAN). This system employs optical time division multiplexing (OTDM) over one WDM channel to multiplex and transmit various types of wireless interfaces such as 3.9G, Wireless LAN and WiMAX. A combination of star and bus topologies has employed to cover a wider service area. The optical transmission loss is caused notably at remote base stations (RBSs) quipped on a WDM bus link. The loss is relatively small, but at the RBS far from the center station (CS), the RBS suffers the large accumulated loss, so the reduction of cell size provides the increasing of the number of RBSs, causes the degradation of the SNR of RoF link. This paper addresses this trade-off problem, and considers the application to the actual service area by the channel capacity investigation of RoF-DAS over WDM-PON with computer simulation. Then, this paper focuses on the flexibility of RoF-DAS over WDM-PON, considers the adaptive wireless cell configuration according to population fluctuations of day and night, or densely populated areas and sparsely populated areas, respectively.

    In operational weather forecasting, the assimilation of brightness temperatures from satellite sounders, instead of assimilation of 1D-retrievals has become increasingly common practice over the last two decades. Compared to these systems, assimilation of trace gases is still at a relatively early stage of development, and efforts to directly assimilate radiances instead of retrieved products have just begun a few years ago, partially because it requires much more computation power due to the employment of a radiative transport forward model (FM). This paper will focus on a method to assimilate SBUV/2 radiances (albedos) into the Global Earth Observation System Ozone Data Assimilation Scheme (GEOS-03DAS). While SBUV-type instruments cannot compete with newer sensors in terms of spectral and horizontal resolution, they feature a continuous data record back to 1978, which makes them very valuable for trend studies. Assimilation can help spreading their ground coverage over the whole globe, as has been previously demonstrated with the GEOS-03DAS using SBUV Version 6 ozone profiles. Now, the DAS has been updated to use the newly released SBUV Version 8 data. We will compare pre]lmlnarv results of SBUV radiance assimilation with the assimilation of retrieved ozone profiles, discuss methods to deal with the increased computational load, and try to assess the error characteristics and future potential of the new approach.

    The toxic characteristics of arsenic species, As(V) and As(III) result in ecological risks. Arsenic tolerant bacterium was isolated and identified as the Bacillus licheniformis DAS-2 through 16SrDNA sequencing. B. licheniformis DAS-2 was efficient to tolerate and remove both the As(V)[MIC 8mM] and As(III)[MIC 6mM] from the growth medium. The potential for the removal/uptake of arsenic from the 3, 5 and 7mM As(V) enriched growth media was 100%, 60% and 35% respectively and from the 1, 3 and 5mM As(III) enrichment it was 100%, 99% and 58% respectively at neutral pH. 80% of uptake As(V) was reduced to As(III) in 3mM As(V) enrichment which was gradually decreased to only 17% at 7mM As(V) enrichment at neutral pH. The arsenic toxicity in B. licheniformis DAS-2 was found modulated by pH and was examined through alteration in growth, uptake/removal, reduction and measurement of chemical toxicity. PMID:27135959

    Event DAS-40278-9 maize grain (containing the aryloxyalkanoate dioxygenase-1 protein), a non-transgenic near-isogenic maize grain, or one of three commercial maize grains were included in the diets of broiler chickens for six weeks. Growth, feed conversion, and carcass measurements indicated no significant difference between the groups fed the diets containing the DAS-40278-9 maize grain and those fed diets containing the matched control grain. The absence of adverse effects in this study supports the dietary safety of the AAD-1 protein expressed in event DAS-40278-9 maize.

    Neste trabalho apresentamos imagens de alta resolução angular da região HII gigante G333.1-0.4 obtidas através dos filtros J, H e K no telescópio de 4-m do CTIO. Este trabalho faz parte de um estudo de regiões HII gigantes no infravermelho próximo que tem por objetivo estudar a natureza da formação de estrelas massivas e traçar a estrutura espiral de nossa galáxia. Nossa determinação da distância é baseada no método da paralaxe espectroscópica de estrelas OB localizadas na seqüência principal de idade zero (ZAMS) do Diagrama HR. No caso de G333.1-0.4, a magnitude aparente das estrelas localizadas na ZAMS indica que a distância não pode ser maior do que o limite inferior determinado por técnica rádio (2,8 kpc). Resultados semelhantes foram encontrados para regiões estudadas anteriormente, reforçando a idéia de que a taxa de formação estelar na Via Láctea é menor do que o determinado a partir de dados rádio. Nossos resultados mais recentes sobre o conteúdo estelar de G333.1-0.4 revelaram vários objetos que possuem cores bastante avermelhadas (H-K > 2,0). Nós identificamos estes objetos usando os diagramas cor-cor e cor-magnitude dos aglomerados. Estes objetos apresentam um forte excesso em emissão na banda K e possivelmente se tratam de estrelas do tipo OB envolvidas por um disco/envelope circumestelar espesso. O estudo da função de massa inical desta região, em conjunto com resultados de nossos trabalhos anteriores, aponta para uma IMF independente da posição galática. A contagem de estrelas nos fornece um valor para o número de fótons no contínuo de Lyman que corrobora com a afirmação de que G333.1-0.4 se encontra mais próxima da menor distância determinada por rádio.

    Der Ausbau erneuerbarer Energien ist in Deutschland eine zentrale und politisch konsensfähige Forderung, um die Energieversorgung klimafreundlich und nachhaltig zu gestalten. Speziell ländliche Regionen rücken dabei in den Fokus, bieten sie doch aufgrund ihrer hohen Flächenverfügbarkeit große Potenziale für die flächenintensiven dezentralen Energieformen. Folglich erkennen Kommunen zunehmend das Entwicklungspotenzial dieser Technologien und sehen sie auch als Chance, neue wirtschaftliche Impulse vor Ort zu setzen. Der Beitrag skizziert die rasante Entwicklung der Photovoltaik im Regierungsbezirk Niederbayern und diskutiert anhand des Beispiels die Folgen für eine nachhaltige Regionalentwicklung.

  4. Hermann Cohen's Das Princip der Infinitesimal-Methode: The history of an unsuccessful book.

    PubMed

    Giovanelli, Marco

    2016-08-01

    This paper offers an introduction to Hermann Cohen's Das Princip der Infinitesimal-Methode (1883), and recounts the history of its controversial reception by Cohen's early sympathizers, who would become the so-called 'Marburg school' of Neo-Kantianism, as well as the reactions it provoked outside this group. By dissecting the ambiguous attitudes of the best-known representatives of the school (Paul Natorp and Ernst Cassirer), as well as those of several minor figures (August Stadler, Kurd Lasswitz, Dimitry Gawronsky, etc.), this paper shows that Das Princip der Infinitesimal-Methode is a unicum in the history of philosophy: it represents a strange case of an unsuccessful book's enduring influence. The "puzzle of Cohen's Infinitesimalmethode," as we will call it, can be solved by looking beyond the scholarly results of the book, and instead focusing on the style of philosophy it exemplified. Moreover, the paper shows that Cohen never supported, but instead explicitly opposed, the doctrine of the centrality of the 'concept of function', with which Marburg Neo-Kantianism is usually associated.

    2015-01-01

    There is a need to develop an outcome measure specific to music therapy in dementia that reflects a holistic picture of the therapy process and outcome. This study aimed to develop a clinically relevant and scientifically robust music therapy outcome measure incorporating the values and views of people with dementia. Focus groups and interviews were conducted to obtain qualitative data on what music meant to people with dementia and the observed effects of music. Expert and peer consultations were conducted at each stage of the measure development to maximise its content validity. The new measure was field-tested by clinicians in a care home. Feedback from the clinicians and music therapy experts were incorporated during the review and refinement process of the measure. A review of the existing literature, the experiential results and the consensus process enabled the development of the new outcome measure “Music in Dementia Assessment Scales (MiDAS)”. Analysis of the qualitative data identified five key areas of the impact of music on people with dementia and they were transformed as the five Visual Analogue Scale (VAS) items: levels of Interest, Response, Initiation, Involvement and Enjoyment. MiDAS comprises the five VAS items and a supplementary checklist of notable positive and negative reactions from the individual. This study demonstrates that it is possible to design and develop an easy to apply and rigorous quantitative outcome measure which has a high level of clinical relevance for people with dementia, care home staff and music therapists.

    2014-01-01

    The Operational Land Imager (OLI) is a multi-spectral radiometer hosted on the recently launched Landsat-8 satellite. OLI includes a suite of relatively narrow spectral bands at 30-meter spatial resolution in the visible to shortwave infrared that make it a potential tool for ocean color radiometry: measurement of the reflected spectral radiance upwelling from beneath the ocean surface that carries information on the biogeochemical constituents of the upper ocean euphotic zone. To evaluate the potential of OLI to measure ocean color, processing support was implemented in SeaDAS, which is an open-source software package distributed by NASA for processing, analysis, and display of ocean remote sensing measurements from a variety of satellite-based multi-spectral radiometers. Here we describe the implementation of OLI processing capabilities within SeaDAS, including support for various methods of atmospheric correction to remove the effects of atmospheric scattering and absorption and retrieve the spectral remote-sensing reflectance (Rrs; sr exp 1). The quality of the retrieved Rrs imagery will be assessed, as will the derived water column constituents such as the concentration of the phytoplankton pigment chlorophyll a.

    A década de 70 do século passado foi marcada pelo estudo das concepções alternativas que os alunos trazem para a sala de aula. A identificação destas concepções foi o ponto de partida para promover a mudança conceitual, onde as pré-concepções seriam trocadas pelas concepções científicas. Na década seguinte, surgiram muitas propostas de estratégias educacionais para facilitar esta troca, na sua maioria baseadas na idéia do conflito cognitivo, proposta por Piaget. Entretanto, os resultados pouco animadores conduziram à percepção de que a mudança conceitual é um processo mais complexo. Pelas idéias da Ciência Cognitiva, a mudança conceitual é uma mudança progressiva dos modelos mentais que o aluno tem sobre o mundo físico, através de enriquecimento e revisão. A causa das Estações do Ano é um tópico sobre o qual a maioria dos estudantes apresenta concepções alternativas. Os autores fizeram um levantamento sobre as pré-concepções encontradas em trabalhos sobre o tema (16 referências), procurando encontrar elementos comuns que indicassem a presença de modelos mentais específicos. As pré-concepções encontradas na literatura foram obtidas usando-se diversas metodologias (desde entrevistas clínicas até questionários de múltipla escolha) e envolvendo alunos e professores de diferentes regiões geográficas. A partir de uma análise aprofundada de cada trabalho, e utilizando-se a técnica das Redes Sistêmicas, chegou-se a conclusão que as diversas pré-concepções identificadas (em torno de 50), poderiam ser representadas por 6 modelos mentais, onde a explicação da causa das estações do ano tem um mecanismo causal responsável. Os mecanismos causais identificados foram: a dependência da distância, a dependência da orientação, a dependência conjunta da distância e orientação, a dependência da obstrução, a dependência da velocidade e a dependência da inclinação dos raios solares.

    The maintenance of undifferentiated human pluripotent stem cells (hPSC) under xeno-free condition requires the use of human feeder cells or extracellular matrix (ECM) coating. However, human-derived sources may cause human pathogen contamination by viral or non-viral agents to the patients. Here we demonstrate feeder-free and xeno-free culture system for hPSC expansion using diffusion assisted synthesis-grown nanocrystalline graphene (DAS-NG), a synthetic non-biological nanomaterial which completely rule out the concern of human pathogen contamination. DAS-NG exhibited advanced biocompatibilities including surface nanoroughness, oxygen containing functional groups and hydrophilicity. hPSC cultured on DAS-NG could maintain pluripotency in vitro and in vivo, and especially cell adhesion-related gene expression profile was comparable to those of cultured on feeders, while hPSC cultured without DAS-NG differentiated spontaneously with high expression of somatic cell-enriched adhesion genes. This feeder-free and xeno-free culture method using DAS-NG will facilitate the generation of clinical-grade hPSC. PMID:26846167

    In this article, we present a valid and reliable instrument which measures the attitude of in-service and pre-service primary teachers toward teaching science, called the Dimensions of Attitude Toward Science (DAS) Instrument. Attention to the attitudes of primary teachers toward teaching science is of fundamental importance to the professionalization of these teachers in the field of primary science education. With the development of this instrument, we sought to fulfill the need for a statistically and theoretically valid and reliable instrument to measure pre-service and in-service teachers' attitudes. The DAS Instrument is based on a comprehensive theoretical framework for attitude toward (teaching) science. After pilot testing, the DAS was revised and subsequently validated using a large group of respondents (pre-service and in-service primary teachers) (N = 556). The theoretical underpinning of the DAS combined with the statistical data indicate that the DAS possesses good construct validity and that it proves to be a promising instrument that can be utilized for research purposes, and also as a teacher training and coaching tool. This instrument can therefore make a valuable contribution to progress within the field of science education.

    Data assimilation has become a popular method to integrate observations from multiple sources with land surface models to improve predictions of the water and energy cycles of the soil-vegetation-atmosphere continuum. In recent years, several land data assimilation systems have been developed in different research agencies. Because of the software availability or adaptability, these systems are not easy to apply for the purpose of multivariate land data assimilation research. Multivariate data assimilation refers to the simultaneous assimilation of observation data for multiple model state variables into a simulation model. Our main motivation was to develop an open source multivariate land data assimilation framework (DasPy) which is implemented using the Python script language mixed with C++ and Fortran language. This system has been evaluated in several soil moisture, L-band brightness temperature and land surface temperature assimilation studies. The implementation allows also parameter estimation (soil properties and/or leaf area index) on the basis of the joint state and parameter estimation approach. LETKF (Local Ensemble Transform Kalman Filter) is implemented as the main data assimilation algorithm, and uncertainties in the data assimilation can be represented by perturbed atmospheric forcings, perturbed soil and vegetation properties and model initial conditions. The CLM4.5 (Community Land Model) was integrated as the model operator. The CMEM (Community Microwave Emission Modelling Platform), COSMIC (COsmic-ray Soil Moisture Interaction Code) and the two source formulation were integrated as observation operators for assimilation of L-band passive microwave, cosmic-ray soil moisture probe and land surface temperature measurements, respectively. DasPy is parallelized using the hybrid MPI (Message Passing Interface) and OpenMP (Open Multi-Processing) techniques. All the input and output data flow is organized efficiently using the commonly used NetCDF file

    This paper describes upgrades to the Data Acquisition System for the Experimental Projects Department at PPL, especially in support of the PBX-M upgrade to be completed this year. Hardware and software maintenance problems with the old configuration, consisting of a DEC KL-10 and eight PDP-11's, are described. The real-time software and hardware performance requirements and projections for CAMAC I/O and data analysis and display are presented. Described are three applications that have realtime requirements and are located on separate processors, connected to PPPL's VAX Cluster by an Ethernet link. Building upon a previous large software base, general-purpose subroutine libraries and utilities are being emphasized. The most useful of these are described. The use of software packages from DEC, third-party vendors, and the fusion community, is also described. The new approaches to software development that are being incorporated into the DAS efforts are discussed. Specific future challenges are also described.

    Neste trabalho é apresentada uma demonstração do uso dos diferentes desenvolvimentos em séries para as equações de perturbação em Mecânica Celeste no marco Hamiltoniano. Em trabalhos clássicos como os de Poincaré (Poincaré, 1893) por exemplo, já esta planteado o uso de potências não inteiras no pequeno parâmetro, o que evidencia a não analiticidade das funções quando uma ressonância ocorre. Nestes trabalhos os desenvolvimentos são na raíz quadrada da massa de Júpiter (o pequeno parâmetro). Mais recentemente (Ferraz-Mello, 1985) outros tipos de desenvolvimentos foram aplicados modificando substancialmente as ordens de grandeza e a velocidade de convergência das séries. Com esta abordagem, os desenvolvimentos foram expressados em termos da raíz cúbica do pequeno parâmetro. Neste trabalho apresentamos um enfoque geral, onde os diferentes tipos de desenvolvimentos em séries de Puiseux (Valiron, 1950) são obtidos a partir da aplicação de Teorema de Preparação de Weierstrass (Goursat, 1916) considerando a equação de Hamilton-Jacobi como uma equação algébrica. Os resultados são aplicados ao problema restrito dos três corpos em ressonância de primeira ordem e, dependendo da grandeza da excentricidade do asteróide em relação à de Júpiter, obtemos os diferentes desenvolvimentos, em raíz quadrada ou raíz cúbica da massa de Júpiter.

As taxas de produção dos radicais CN, C2 e C3, obtidos a partir de dados disponíveis na literatura, revelam que, além de muito brilhante, o Hyakutake é um cometa "normal" no sentido de Cochran (1986). Desse modo, deduzimos as taxas de perdas de água (em moléculas/s) a partir da análise de sua magnitude visual aparente, e as convertemos em taxas de perdas de gás (em g/s), despreendido pelo nucleo cometário. Com o auxílio do modelo fotométrico clássico da poeira, realizamos uma análise sistemática e uniforme dessa componente cometária, a partir dos fluxos observacionais no contínuo, para os comprimentos de onda 365,0 e 484,5 nm, assumindo que esses fluxos são o resultado da radiação solar espalhada por grãos de partículas micrométricos presentes na coma. Com isso, pudemos obter as taxas de produção (em g/s), cores (relativas à cor neutra solar), e as dimensões efetivas médias das partículas de poeira, bem como as razões poeira-gás.

    This work developed at the Planetarium of Pará employing workshops designed for visitor schools (public, private, specials groups), promotes the popularization of the Ethnoastronomy with the aim of diffusing values based on a cultural diversity tolerance and the need of harmonic interplay between people and environment. Using stories and debates, the relationship between humans and the Cosmos is traced from antiquity until today, with the help of slides as a didactic resource. Thus, many conceptions about the origin of the Universe are shown; as well as some constellations created along the History, ending with the present scientific manner of know and explain the World. We then demonstrate the links between space, time and culture with the Cosmos vision. The need to think the World within a plural context to create respect for other different persons is emphasized. Este trabalho, desenvolvido no Planetário do Pará através de oficinas com escolas visitantes (públicas, privadas e grupos especiais), promove a popularização da Etnoastronomia, com o objetivo de difundir valores pautados na tolerância à diversidade cultural e na necessidade da convivência harmônica entre o ser humano e o meio ambiente. Através da contação de histórias e promoção de debate, é tratada a relação dos humanos com o céu desde a antiguidade até os dias atuais, tendo como apoio didático o uso de slides. Assim, são mostradas diversas concepções de origem do Universo; algumas constelações criadas no decorrer da História; e a atual forma científica de conhecer e explicar o mundo. Demonstrando-se, então, a interligação entre espaço, tempo e cultura com a visão do Cosmo. Enfatiza-se a necessidade de se pensar o mundo numa perspectiva relativa ou plural, de forma a propiciar o respeito ao ser diferente.

    A 762-meter Distributed Acoustic Sensing (DAS) array with a channel spacing of one meter was deployed at the Garner Valley Downhole Array in Southern California. The array was approximately rectangular with dimensions of 180 meters by 80 meters. The array also included two subdiagonals within the rectangle along which three-component geophones were co-located. Several active sources were deployed, including a 45-kN, swept-frequency, shear-mass shaker, which produced strong Rayleigh waves across the array. Both DAS and geophone traces were filtered in 2-Hz steps between 4 and 20 Hz to obtain phase velocities as a function of frequency from fitting the moveout of travel times over distances of 35 meters or longer. As an alternative to this traditional means of finding phase velocity, it is theoretically possible to find the Rayleigh-wave phase velocity at each point of co-location as the ratio of DAS and geophone responses, because DAS is sensitive to ground strain and geophones are sensitive to ground velocity, after suitable corrections for instrument response (Mikumo & Aki, 1964). The concept was tested in WPP, a seismic wave propagation program, by first validating and then using a 3D synthetic, full-waveform seismic model to simulate the effect of increased levels of noise and uncertainty as data go from ideal to more realistic. The results obtained from this study provide a better understanding of the DAS response and its potential for being combined with traditional seismometers for obtaining phase velocity at a single location.

    The aim of the present study was to assess the behaviour of llamas (Lama glama) and German blackhead mutton sheep (Ovis orientalis forma aries) when kept under Central European grazing conditions. In total, six adult female sheep and six adult female llamas were observed by direct observation during one week, in which each group was observed for a total time of 24 h. The animals were kept on the same pasture, but the species were raised in separate plots. Forage height before and after the experimental period were determined using a rising plate meter to calculate the average daily dry matter intake (DMI). Llamas had a daily DMI of 0.85%/BW and sheep of 1.04%/BW, respectively. The following behaviours were recorded by direct observation: grazing standing up, grazing lying down, ruminating standing up, ruminating lying down, lying down, lying down lateral and standing. Both species grazed for more than 50% of the time. Ruminating was predominantly performed while standing and lying by sheep (about 50% of the night and 12% of the day) and while lying by llamas (54% of the night and 10% of the day). In conclusion, sheep and llamas differed in grazing behaviour and daily biorhythm. These differences indicate that sheep and llamas may not synchronize their behaviour when co-grazed, though particularly in co-grazing studies the observation period should be extended.

    Cananga odorata (Lam.) Hook.f. & Thomson forma genuina (Annonaceae) is a tropical tree, grown for the production of ylang-ylang essential oil, which is extracted from its fresh and mature flowers. Despite its economic and social importance, very little information is available on its variability and the possible factors causing it. Therefore, the relationship between the genetic structure, revealed by amplified fragment length polymorphism (AFLP), and the essential oil chemical composition, determined by GC/MS analysis, of ylang-ylang grown in semi-managed systems in three Indian Ocean islands (Grande Comore, Mayotte, and Madagascar) was investigated. Our results revealed a low genetic variation within plantations and contrasted situations between islands. Variations of the chemical composition could be observed within plantations and between islands. The genetic differentiation pattern did not match the observed pattern of chemical variability. Hence, the chemical variation could not be attributed to a genetic control. As Grande Comore, Madagascar, and Mayotte present different environmental and agronomic conditions, it can be concluded that the influence of these conditions on the ylang-ylang essential oil composition is consistent with the patterns observed. Finally, several strategies were proposed to valorize the chemical composition variations. PMID:22782885

    Small molecule effectors regulate gene transcription in bacteria by altering the DNA-binding affinities of specific repressor proteins. Although the GntR proteins represent a large family of bacterial repressors, only little is known about the allosteric mechanism that enables their function. DasR from Streptomyces coelicolor belongs to the GntR/HutC subfamily and specifically recognises operators termed DasR-responsive elements (dre-sites). Its DNA-binding properties are modulated by phosphorylated sugars. Here, we present several crystal structures of DasR, namely of dimeric full-length DasR in the absence of any effector and of only the effector-binding domain (EBD) of DasR without effector or in complex with glucosamine-6-phosphate (GlcN-6-P) and N-acetylglucosamine-6-phosphate (GlcNAc-6-P). Together with molecular dynamics (MD) simulations and a comparison with other GntR/HutC family members these data allowed for a structural characterisation of the different functional states of DasR. Allostery in DasR and possibly in many other GntR/HutC family members is best described by a conformational selection model. In ligand-free DasR, an increased flexibility in the EBDs enables the attached DNA-binding domains (DBD) to sample a variety of different orientations and among these also a DNA-binding competent conformation. Effector binding to the EBDs of DasR significantly reorganises the atomic structure of the latter. However, rather than locking the orientation of the DBDs, the effector-induced formation of β-strand β* in the DBD-EBD-linker segment merely appears to take the DBDs ‘on a shorter leash’ thereby impeding the ‘downwards’ positioning of the DBDs that is necessary for a concerted binding of two DBDs of DasR to operator DNA.

  11. Using Distributed Acoustic Sensing (DAS) for Multichannel Analysis of Surface Waves (MASW) to Evaluate Ground Stiffness

    Since its introduction by Park, et al. (1999), Multichannel Analysis of Surface Waves (MASW) has become an invaluable geophysical technique for geotechnical site investigation. The technique is primarily focused on developing 2-D and 3-D shear stiffness vs. depth images of the near surface. MASW involves measuring surfaces waves of various frequencies produced by a seismic source, such as a sledgehammer or vibroseis source, which is evaluated to determine the velocity of the shear waves propagating through the subsurface at shallow depths. Traditionally, this technique relies on a long string of geophones as receivers. However, our study utilized a Distributed Acoustic Sensor array to detect ground motion caused by passing surface waves at a spatial resolution of one meter. The purpose of this investigation is to compare the effectiveness of using a DAS array for MASW data collection instead of traditional geophones. Data were collected at the Network for Earthquake Engineering Simulation's Garner Valley Downhole Array site (NEES's GVDA). Various time-frequency filtering and moving window cross correlation (MWCC) techniques were examined for extracting the surface wave dispersion. The results were found to be in good agreement with those previously obtained by Stokoe et al. (2004).

    The advent of the commercial space launch industry and NASA's more recent resumption of operation of Stennis Space Center's large test facilities after thirty years of contractor control resulted in a need for a non-proprietary data acquisition systems (DAS) software to support government and commercial testing. The software is designed for modularity and adaptability to minimize the software development effort for current and future data systems. An additional benefit of the software's architecture is its ability to easily migrate to other testing facilities thus providing future commonality across Stennis. Adapting the software to other Rocket Propulsion Test (RPT) Centers such as MSFC, White Sands, and Plumbrook Station would provide additional commonality and help reduce testing costs for NASA. Ultimately, the software provides the government with unlimited rights and guarantees privacy of data to commercial entities. The project engaged all RPT Centers and NASA's Independent Verification & Validation facility to enhance product quality. The design consists of a translation layer which provides the transparency of the software application layers to underlying hardware regardless of test facility location and a flexible and easily accessible database. This presentation addresses system technical design, issues encountered, and the status of Stennis development and deployment.

    Marine multicellular organisms in composition with their associated microbiota-representing metaorganisms-are confronted with constantly changing environmental conditions. In 2110, the seawater temperature is predicted to be increased by ~5°C, and the atmospheric carbon dioxide partial pressure (pCO2) is expected to reach approximately 1000 ppm. In order to assess the response of marine metaorganisms to global changes, e.g., by effects on host-microbe interactions, we evaluated the response of epibacterial communities associated with Fucus vesiculosus forma mytili (F. mytili) to future climate conditions. During an 11-week lasting mesocosm experiment on the island of Sylt (Germany) in spring 2014, North Sea F. mytili individuals were exposed to elevated pCO2 (1000 ppm) and increased temperature levels (Δ+5°C). Both abiotic factors were tested for single and combined effects on the epibacterial community composition over time, with three replicates per treatment. The respective community structures of bacterial consortia associated to the surface of F. mytili were analyzed by Illumina MiSeq 16S rDNA amplicon sequencing after 0, 4, 8, and 11 weeks of treatment (in total 96 samples). The results demonstrated that the epibacterial community structure was strongly affected by temperature, but only weakly by elevated pCO2. No interaction effect of both factors was observed in the combined treatment. We identified several indicator operational taxonomic units (iOTUs) that were strongly influenced by the respective experimental factors. An OTU association network analysis revealed that relationships between OTUs were mainly governed by habitat. Overall, this study contributes to a better understanding of how epibacterial communities associated with F. mytili may adapt to future changes in seawater acidity and temperature, ultimately with potential consequences for host-microbe interactions.

  18. Sensitivity of Global Modeling Initiative CTM predictions of Antarctic ozone recovery to GCM and DAS generated meteorological fields

    We use the Global Modeling Initiative chemistry and transport model to simulate the evolution of stratospheric ozone between 1995 and 2030, using boundary conditions consistent with the recent World Meteorological Organization ozone assessment. We compare the Antarctic ozone recovery predictions of two simulations, one driven by meteorological data from a general circulation model (GCM), the other using the output of a data assimilation system (DAS), to examine the sensitivity of Antarctic ozone recovery predictions to the characteristic dynamical differences between GCM and DAS-generated meteorological data. Although the age of air in the Antarctic lower stratosphere differs by a factor of 2 between the simulations, we find little sensitivity of the 1995-2030 Antarctic ozone recovery between 350 K and 650 K to the differing meteorological fields, particularly when the recovery is specified in mixing ratio units. Relative changes are smaller in the DAS-driven simulation compared to the GCM-driven simulation due to a surplus of Antarctic ozone in the DAS-driven simulation which is not consistent with observations. The peak ozone change between 1995 and 2030 in both simulations is {approx}20% lower than photochemical expectations, indicating that changes in ozone transport at 450 K between 1995 and 2030 constitute a small negative feedback. Total winter/spring ozone loss during the base year (1995) of both simulations and the rate of ozone loss during August and September is somewhat weaker than observed. This appears to be due to underestimates of Antarctic Cl{sub y} at the 450 K potential temperature level.

  19. Alice Vance ("Das Bärenweib"): a historical case of Nievergelt syndrome.

    Several malformed individuals were presented at the World Exhibition in Antwerp in 1894. Among them was Mrs. Alice Vance from Mount Pleasant, Texas, with congenital limb defects, and Mr. Eugen Berry, who had asymmetrical, monstrous enlargement and macrodactyly of the feet, i.e., Proteus syndrome. After the World Exhibition Mrs. Vance presented herself to the public in Castan's Panopticon imitating a bear. She became famous under the stage name "Das Bärenweib" ("the bear-like woman") and was examined by several German clinicians, and her malformations were considered to be of high scientific interest. Mrs. Vance had mesomelic dwarfism and her mother was known to have similar malformations. Her limb deficiencies were generally considered a unique congenital condition those days, and the diagnosis of "a maternally inherited malformation of the forearms and the shanks" [Daffner 1898: Munch Med Wochenschr 25:782] was made. Virchow [1897: Verh Berl Ges Ethnol Urgeschichte 29:624], feeling attacked by a daily newspaper stating that the physicians as well as the police of Berlin had missed the diagnosis of an "English disease," eventually exercised his authority and diagnosed Alice Vance as a "phocomelic." Clearly, she was not a phocomelic according to past and current definition of this term. Thus, from a historical point of view, the story illustrates how pressure from the daily press altered the definition of an up-to-then precisely defined medical term for decades. According to the clinical data and an X-ray report available from the literature, Alice Vance had a dominantly inherited type of mesomelic dwarfism. We propose the diagnosis of Nievergelt syndrome.

    Natural convective heat transfer and fluid flow in an open porous cavity filled with a nanofluid is studied numerically using the Tiwari and Das nanofluid model. The transport equations for mass, momentum and energy formulated in dimensionless stream function and temperature are solved numerically using a second-order accurate finite difference method. Particular efforts are focused on the effects of the governing parameters on the heat and fluid flow. It is found that an increase in undulation number of the wavy vertical wall leads to an attenuation of convective flow and a decrease in the heat transfer rate.

    Bacillus thuringiensis (Bt) event DAS-81419-2 (Conkesta technology) in soybean, Glycine max (L.) Merrill, expresses Cry1F and Cry1Ac proteins to provide protection from feeding by several lepidopteran pests. A total of 27 field experiments across nine locations were conducted from 2011 to 2015 in southern and central Brazil to characterize the efficacy of DAS-81419-2 soybean infested with Anticarsia gemmatalis Hübner (Lepidoptera: Erebidae), Chrysodeixis includens (Walker) (Lepidoptera: Noctuidae), Heliothis virescens (F.) (Lepidoptera: Noctuidae), and Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) during vegetative (V4) and reproductive (R2 and R4) crop developmental stages. The efficacy of DAS-81419-2 was compared to that of a non-Bt isogenic variety managed with or without applications of commercial foliar insecticides for lepidopteran control. DAS-81419-2 soybean consistently experienced defoliation levels of 0.5% or less (compared with 20.05-56.74% in the non-Bt, nonsprayed treatment) and larval survival of < 0.1% in all four species across the vegetative and reproductive plant stages evaluated. The efficacy of DAS-81419-2 was significantly higher than commercial foliar insecticides applied to the non-Bt variety. DAS-81419-2 soybeans containing two highly effective Bt proteins are expected to be a more robust IRM tool compared to single-trait Bt technologies. The consistent efficacy of DAS-81419-2 soybeans across years, locations, and crop stages suggests that it will be a valuable product for management of hard-to-control key lepidopteran pests in South American soybean production.

    The aim of this study was to survey factors related to EULAR good response, the DAS-28 definition of remission, ACR 50 response, sustained response to tumor necrosis factor inhibitors (TNF-I) therapy in biologic naïve patients with refractory rheumatoid arthritis. This was a single center observational clinical prospective 2 years' study, EULAR response criteria, DAS 28, HAQ and radiographic changes were recorded. Eighty patients included (64 females and 16 males, mean age was 48.4 + -17.9 years, mean disease duration 7.3 + -5.9 years). At 6 months 70% achieved EULAR good response, 51.8% achieved DAS-28 remission. Good response/sustained responses inversely correlated with baseline DAS-28 and radiographic erosions P <0.05. EULAR good response/remission by 6 months, sustained response at 2 years positively correlated with the decline in RF titers (r = 0.33, P < 0.05 & r = 0.30, P < 0.03 respectively), negatively correlated with the baseline HAQ. Regression analysis identified higher serum hemoglobin concentration, lower baseline HAQ scores, and the absence of radiographic erosions as significant predictors of good as well as sustained responses after adjustment for potential covariates. Methotrexate was associated with favorable responses and remission at 6 months (ORs = 1.13, 1.30 respectively). The study concluded that a lower baseline DAS-28 and HAQ scores, the lack of radiographic erosions favored EULAR good response and were significant predictors of sustained response to TNF-I.

    The field test of Distributed Acoustic Sensing (DAS) conducted at Garner Valley, California on September 11-12, 2013 provided a continuous overnight record of ambient noise. The DAS array recorded ground motions every one meter of optical cable that was arranged approximately in the shape of a rectangle with dimensions of 160 m by 80 m. The long dimension of the array was adjacent to a state highway. Three hours of record were used to compute noise cross-correlation functions (NCFs) in one-minute windows. The trace from each sensor channel was pre-processed by downsampling to 200 Hz, followed by normalization in the time-domain and bandpass filtering between 2 and 20 Hz (Bensen et al., 2007). The one-minute NCFs were then stacked using the time-frequency domain phase-weighted stacking method (Schimmel & Gallart, 2007). The NCFs between channels were asymmetrical reflecting the direction of traffic noise. The group velocities were found using the frequency-time analysis method. The energy was concentrated between 5 and 15 Hz, which falls into the typical traffic noise frequency band. The resulting velocities were between 100 and 300 m/s for frequencies between 10 and 20 Hz, which are in the same range as described in the results for surface-wave dispersion obtained using an active source for the same site (Lancelle et al., 2015). The group velocity starts to decrease for frequencies greater than ~10 Hz, which was expected on the basis of a previous shear-wave velocity model (Steidl et al., 1996). Then, the phase velocity was calculated using the multichannel analysis of surface wave technique (MASW - Park et al., 1999) with 114 NCFs spaced one meter apart. The resulting dispersion curve between 5 and 15 Hz gave phase velocities that ranged from approximately 170 m/s at 15 Hz to 250 m/s at 5 Hz. These results are consistent with other results of active-source DAS and seismometer records obtained at the Garner Valley site (e.g., Stokoe et al. 2004). This analysis is

    The transgenic soybean event DAS-81419-2 contains genes that encode the Cry1F, Cry1Ac, and PAT proteins. Cry1F and Cry1Ac provide protection against key lepidopteran insect pests, while PAT confers tolerance to the herbicide glufosinate. To satisfy regulatory requirements for the safety evaluation of transgenic crops, studies were conducted in the United States and Brazil to evaluate the nutrient and antinutrient composition of event DAS-81419-2 soybean. On the basis of the results of these studies, event DAS-81419-2 soybean is compositionally equivalent to nontransgenic soybean. This conclusion concurs with numerous other published studies in soybean and other crops where compositional equivalence between the transgenic crop and its nontransgenic comparator has been demonstrated.

    Kirschner, Stefan

    Es ist erstaunlich, daß sowohl Friis als auch Dreyer in ihrer Ausgabe der Briefe Tycho Brahes den Brief vom 14. November 1577 an Peter Sørensen, die erste bekannte Nachricht Brahes von seiner Entdeckung des Kometen von 1577, nur unvollständig, und zwar ohne den astronomischen Inhalt, ediert haben. Der Brief, dessen Original sehr wahrscheinlich nicht mehr existiert, wurde von dem Kieler Arzt und Medizinprofessor Johann Daniel Major (1634 - 1693) in Kopenhagen in sein Reisetagebuch kopiert. Das Original des Majorschen Reisetagebuches ist verschollen, doch es existieren zwei Abschriften davon (Kopenhagen, Königl. Bibl., Ny Kgl. Sml., 365, Fol. u. Ledreborg, 410, Fol.). Im folgenden wird nach einer kurzen Beschreibung des Stellenwerts, den der Komet von 1577 für Brahe besaß, der Brief nach diesen beiden Abschriften kritisch ediert, mit einer deutschen Übersetzung versehen und kurz kommentiert.

    Distributed fiber-optic sensing methods have been used since the 1980's for continuous monitoring of near-surface soil properties, typically exploiting Raman scattering to measure temperature (DTS) or stimulated Brillouin scattering to measure strain (DSS). Recent advances in high speed measurement of Rayleigh scattering has enabled distributed recording of seismic waves over long sections of fiber; this approach, referred to as distributed acoustic sensing (DAS) has the potential to allow nearly continuous monitoring of near-surface mechanical properties, a crucial target for geotechnical management of infrastructure dependent on soil strength. We present initial results from our effort to build a real-time soil property monitoring system based on DAS; our approach employs seismic interferometry and dispersion analysis of ambient noise generated by infrastructure to provide a continuously updated model of shear modulus. Our preliminary results include an in-depth investigation of DAS fiber response in the context of active sources; this component of our study verifies classical models for the azimuthal response of straight fibers to propagating surface waves. We also explore the "noisescape" of linear infrastructure and show a usable seismic signal band of 8-40 hz at a series of sites, primarily consisting of Rayleigh waves. Finally, we present preliminary results from a DAS monitoring array installed at the Richmond Field Station near a heavily used road and compare interferometric processing of the acquired data to that generated by surface deployment of geophones.

    Nós temos selecionado uma amostra de estrelas anãs brancas DA (atmosfera de hidrogênio) a partir dos índices de Strömgren cujos valores estão próximos a região de instabilidade das estrelas anãs brancas DA variáveis, as chamadas estrelas DAV ou ZZ Ceti. O objetivo é determinar os parâmetros fundamentais (temperatura efetiva, Teff, aceleração da gravidade, log g, e massa) destas estrelas para verificar quais os parâmetros estelares estão envolvidos com o mecanismo de pulsação das estrelas DAV. Nós obtemos, até agora, mais de 120 espectros óticos de estrelas DA. Entre as estrelas selecionadas há 20 estrelas variáveis (DAV). Assim, podemos verificar se existem ou não estrelas não variáveis dentro da faixa de instabilidade das estrelas ZZ Ceti. Neste trabalho nós apresentamos a determinação dos parâmetros atmosféricos (temperatura efetiva, Teff, e aceleração da gravidade, log g) das estrelas anãs brancas DA usando os novos modelos de atmosfera ML2/a = 0.6. Estes modelos têm sido utilizados recentemente por fornecerem uma excelente consistência interna na determinação das temperaturas nas regiões do ultra-violeta e ótico. Os parâmetros atmosféricos são determinados espectroscopicamente através da comparação do fluxo de energia das linhas de Balmer (Hb à H9) entre os espectros observados e sintéticos (gerados pelos modelos de atmosfera). As temperaturas obtidas com os novos modelos são, em geral, menores (~ 1000 K menos) que as temperaturas determinadas anteriormente, com modelos ML1. Os valores de log g não mudaram significativamente (menos de 10%). A faixa de instabilidade das DAVs está entre 11000 e 13000 K, consistente com dados de outros autores.

    Since April 2010, Tembusu virus (TMUV) which is a contagious pathogen of waterfowls, causing symptoms of high fever, loss of appetite and fall in egg production, has been reported in east of China. A double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) which detects for TMUV was developed, using two monoclonal antibodies (mAbs) against the TMUV envelope (E) protein. BALB/c mice were immunized with purified recombinant E protein expressed in E. coli. Three hybridoma cell lines designated as 12B1, 10C6 and 2D2, were screened by cell fusion and indirect ELISA for their ability to recognize different linear epitopes on the E protein, and were characterized subsequently. High-affinity mAbs 12B1 and 2D2 were used as capture and detection antibodies, respectively. The reaction conditions for the DAS-ELISA were optimized for TMUV detection. The cross-reactivity of the DAS-ELISA was determined using TMUV, duck plague virus, avian influenza virus subtype H9, Newcastle disease virus, duck hepatitis A virus type 1 and duck reovirus samples. A total of 191 homogenized tissues of field samples were simultaneously detected by DAS-ELISA and by RT-PCR. The former was found to have a high specificity of 99.1% and a sensitivity of 93.1%. These results reveal a positive coincidence between DAS-ELISA and RT-PCR at a coincidence rate of 95.8%. The method developed in this study can be used for the diagnosis of TMUV infection of duck origin. PMID:24797141

    The single-vibronic-level (SVL) emission spectra of HAsO and DAsO have been simulated by electronic structure/Franck-Condon factor calculations to confirm the spectral molecular carrier and to investigate the electronic states involved. Various multi-reference (MR) methods, namely, NEVPT2 (n-electron valence state second order perturbation theory), RSPT2-F12 (explicitly correlated Rayleigh-Schrodinger second order perturbation theory), and MRCI-F12 (explicitly correlated multi-reference configuration interaction) were employed to compute the geometries and relative electronic energies for the X ˜ 1 A ' and A ˜ 1 A ″ states of HAsO. These are the highest level calculations on these states yet reported. The MRCI-F12 method gives computed T0 (adiabatic transition energy including zero-point energy correction) values, which agree well with the available experimental T0 value much better than previously computed values and values computed with other MR methods in this work. In addition, the potential energy surfaces of the X ˜ 1 A ' and A ˜ 1 A ″ states of HAsO were computed using the MRCI-F12 method. Franck-Condon factors between the two states, which include anharmonicity and Duschinsky rotation, were then computed and used to simulate the recently reported SVL emission spectra of HAsO and DAsO [R. Grimminger and D. J. Clouthier, J. Chem. Phys. 135, 184308 (2011)]. Our simulated SVL emission spectra confirm the assignments of the molecular carrier, the electronic states involved, and the vibrational structures observed in the SVL emission spectra but suggest a loss of intensity in the reported experimental spectra at the low emission energy region almost certainly due to a loss of responsivity near the cutoff region (˜800 nm) of the detector used. Computed and experimentally derived re (equilibrium) and/or r0 {the (0,0,0) vibrational level} geometries of the two states of HAsO are discussed.

    Atol das Rocas, the unique atoll in the South-western Atlantic, is located 144 nautical miles (266 Km) northeast from the city of Natal, NE Brazil and 80 nautical miles from Arquipélago de Fernando de Noronha, with geographic co-ordinates 3 masculine51'S and 33 masculine49"W. It's of volcanic origin and coralline formation. The reef is ellipsoid, its largest axis (E-W) is approximately 3.7 km long, and the shortest (N-S) is 2.5 km. Inside the lagoon, there are two islands: the Ilha do Farol and Ilha do Cemitério, which comprehend 7.2 Km2 of emerged area. The Atol das Rocas lodges 143,000 birds, mainly by Sula dactilatra, S. leucogaster, Anous stolidus, A. minuta and Sterna fuscata. Due to their remote location, the islands remain largely undisturbed by the human activities. Aiming to a first characterization of the entomological diversity and the general trophic niches of atoll's entomofauna, three collects were made (1994, 1995 and 1996) utilizing several methods for a wide sample. One thousand six hundred and six insect specimens were collected belonging to eight orders: 1. Coleoptera - 333 individuals of Dermestidae (Dermestes cadaverinus); Tenebrionidae (Phaleria testacea and morphospecies) and Curculionidae (one morphospecies); 2. Dermaptera - 50 individuals of Carcinophoridae (Anisolabis maritima); 3. Diptera - 281 individuals of Ephydridae (Scatella sp. and Hecamede sp.) and Hippoboscidae (one morphospecies); 4. Hymenoptera - 45 individuals of Formicidae (Brachymyrmex sp.); 5. Lepidoptera - 111 individuals of Microlepidoptera (one morphospecies); 6. Mallophaga - 18 individuals in birds (two morphospecies); 7. Orthoptera - 237 individuals of Acrididae (Schistocerca cancellata), Tridactylidae (one morphospecies) and Blattidae (three morphospecies); 8. Thysanoptera -531 individuals (one morphospecies). Also were collected 112 individuals of Arachnida. The taxa of the Order Araneae were represented by the families: 1. Miturgidae (Cheiracanthium inclusum); 2

    The advent of the commercial space launch industry and NASA's more recent resumption of operation of Stennis Space Center's large test facilities after thirty years of contractor control resulted in a need for a non-proprietary data acquisition system (DAS) software to support government and commercial testing. The software is designed for modularity and adaptability to minimize the software development effort for current and future data systems. An additional benefit of the software's architecture is its ability to easily migrate to other testing facilities thus providing future commonality across Stennis. Adapting the software to other Rocket Propulsion Test (RPT) Centers such as MSFC, White Sands, and Plumbrook Station would provide additional commonality and help reduce testing costs for NASA. Ultimately, the software provides the government with unlimited rights and guarantees privacy of data to commercial entities. The project engaged all RPT Centers and NASA's Independent Verification & Validation facility to enhance product quality. The design consists of a translation layer which provides the transparency of the software application layers to underlying hardware regardless of test facility location and a flexible and easily accessible database. This presentation addresses system technical design, issues encountered, and the status of Stennis' development and deployment.

    Das Lektin aus Pisum sativum, der Gartenerbse, ist Teil der Familie der Leguminosenlektine. Diese Proteine haben untereinander eine hohe Sequenzhomologie, und die Struktur ihrer Monomere, ein all-ß-Motiv, ist hoch konserviert. Dagegen gibt es innerhalb der Familie eine große Vielfalt an unterschiedlichen Quartärstrukturen, die Gegenstand kristallographischer und theoretischer Arbeiten waren. Das Erbsenlektin ist ein dimeres Leguminosenlektin mit einer Besonderheit in seiner Struktur: Nach der Faltung in der Zelle wird aus einem Loop eine kurze Aminosäuresequenz herausgeschnitten, so dass sich in jeder Untereinheit zwei unabhängige Polypeptidketten befinden. Beide Ketten sind aber stark miteinander verschränkt und bilden eine gemeinsame strukturelle Domäne. Wie alle Lektine bindet Erbsenlektin komplexe Oligosaccharide, doch sind seine physiologische Rolle und der natürliche Ligand unbekannt. In dieser Arbeit wurden Versuche zur Entwicklung eines Funktionstests für Erbsenlektin durchgeführt und seine Faltung, Stabilität und Monomer-Dimer-Gleichgewicht charakterisiert. Um die spezifische Rolle der Prozessierung für Stabilität und Faltung zu untersuchen, wurde ein unprozessiertes Konstrukt in E. coli exprimiert und mit der prozessierten Form verglichen. Beide Proteine zeigen die gleiche kinetische Stabilität gegenüber chemischer Denaturierung. Sie denaturieren extrem langsam, weil nur die isolierten Untereinheiten entfalten können und das Monomer-Dimer-Gleichgewicht bei mittleren Konzentrationen an Denaturierungsmittel auf der Seite der Dimere liegt. Durch die extrem langsame Entfaltung zeigen beide Proteine eine apparente Hysterese im Gleichgewichtsübergang, und es ist nicht möglich, die thermodynamische Stabilität zu bestimmen. Die Stabilität und die Geschwindigkeit der Assoziation und Dissoziation in die prozessierten bzw. nichtprozessierten Untereinheiten sind für beide Proteine gleich. Darüber hinaus konnte gezeigt werden, dass auch unter

    The free convection heat transfer of Cu-water nanofluids in a parallelogrammic enclosure filled with porous media is numerically analyzed. The bottom and top of the enclosure are insulated while the sidewalls are subject to limited temperature difference. The Darcy flow and the Tiwari and Das' nanofluid models are considered. The governing dimensionless partial differential equations are numerically solved using a finite difference code. The results are reported for isotherms and streamlines as well as Nusselt number as a function of the volume fraction of nanoparticles, porosity, types of the porous matrix, inclination angle, aspect ratio and different Rayleigh numbers. It is found that the presence of the nanoparticles inside the enclosure deteriorates the heat transfer rate, which is caused due to the increase of dynamic viscosity by the presence of nanoparticles. Therefore, in applications in which the nanofluids are used for their advantages, such as enhanced dielectric properties or antibacterial properties, more caution for the heat transfer design of the enclosure is necessary.

Atualmente estamos desenvolvendo um projeto que visa comparar as propriedades fisicas (principalmente e v¥) dos ventos destes objetos nas Nuvens de Magalhães e na Galaxia. O objetivo é estudar a influência da metalicidade. No presente painel apresentamos uma determinação das velocidades terminais de 11 estrelas, sendo 4 na GNM (Hen S111, 66, R126 e Hen S93), 4 na PNM (Hen S18, S23, S65 e R4) e 3 na Galaxia (CPD-529243, MWC 300 e GG Car). Nossos dados são espectros de alta resolução obtidos no telescópio 1.52m do ESO com o espectrógrafo FEROS. Para determinar as velocidades terminais usamos as linhas Hd e HeI 3888 Å cujas componentes em absorção costumam estar livres de "blends" e estruturas. Nossos resultados sugerem que as velocidades de expansão na GNM são maiores (ainda que apenas ligeiramente) do que aquelas da PNM, como esperado.

    This study aims to measure the psychometric properties of the Das-Naglieri Cognitive Assessment System (D-N CAS) and to determine its clinical utility in a Chinese context. Confirmatory factor analysis (CFA) was conducted to examine the construct validity of the Chinese version of the D-N CAS among a group of 567, normally developed children. Test-retest reliability was examined in a random subsample of 30 children at a five-week interval. The clinical discrimination of the D-N CAS was also examined by comparing children with and without ADHD (18 children in each group) and by comparing children with and without Chinese reading disabilities (18 children in each group). The current Chinese sample demonstrated a four-factor solution for cognitive performance among children with normal development: Planning, Attention, Simultaneous processing and Successive processing (χ2(48)=91.90, p=.000; χ2/df=1.92, RMSEA=.050, GFI=.966, CFI=.954). Moreover, all subtests of the battery demonstrated acceptable test-retest reliability (r=.72-.90, p<.01) at a five-week interval among the subjects of the small subsample. Children with ADHD performed significantly worse than normal children on the Attention factor (p<.001) and the Planning factor (p<.05) of the D-N CAS, and children with Chinese reading disabilities performed significantly worse than normal children on the Simultaneous processing factor (p<.01), the Successive processing factor (p<.001) and the Planning factor (p<.05) of the D-N CAS. These findings suggested that the current four-factor structure of the D-N CAS was similar to the original factor structure of the test. The latent factor of the D-N CAS was fairly stable across the cultures. Moreover, the D-N CAS can distinguish between children with ADHD or Chinese reading disabilities and normally developed children. PMID:21571501

    The present understanding of the physics and technology problems of confining a hot plasma ring by magnetic fields and of heating it to such temperatures that thermonuclear fusions between deuterium and tritium nuclei provide the energy required to maintain this temperature seems to allow to predict the possibility of a self-sustaining thermonuclear reactor. Imbedding this chance into world energy scenarios for the next fifty years, it is shown that fusion reactors of a type of which each may supply about ten slow fission reactors with fissionable material may play a critical rôle by drastically reducing the number of required fast fission breeder reactors.

    Autocorrelation of the EEG was used to registrate a potential from the intact human scalp during intended, but not executed movements (dorsalflexion of the right hallux, imaginated in equal time intervals). This “Motor Intention Potential” (MIP) is a possible electrophysiological sign of the otherwise purely introspectively experienced intention of a voluntary movement and the cortex of the frontal lobes is suspected to be its origin. The average maximum amplitude height is 6 μV, and the potential shows a continuous decrease from the frontal to occipital region. The duration of MIP is in the range of seconds. Methodological questions are discussed, and the MIP is differentiated from other event-, movement- and imagination-related potentials. An attempt is made to place the motor intention potential in the context of existing movement theories.

  2. Biological and phylogenetic characterization of Fusarium oxysporum complex, which causes yellows on Brassica spp., and proposal of F. oxysporum f. sp. rapae, a novel forma specialis pathogenic on B. rapa in Japan.

    Although the causal agent of yellows of Brassica rapa (turnip, pak choi, and narinosa) in Japan was reported in 1996 to be Fusarium oxysporum f. sp. conglutinans, this classification has remained inconclusive because of a lack of detailed genetic and pathogenic studies. Therefore, we analyzed the taxonomic position of this organism using Japanese isolates of F. oxysporum complex obtained from diseased individuals of various B. rapa subspecies. Phylogenetic analyses using partial sequences of the rDNA intergenic spacer region and the mating-type gene (MAT1-1-1alpha-box) showed that B. rapa and cabbage isolates belong to different monophyletic clades that separated at early evolutionary stages. Additionally, correlations were observed between the molecular phylogeny and the vegetative compatibility groups. Isolates from turnip, komatsuna, and narinosa (B. rapa group) did not show pathogenicity against cabbage or broccoli (B. oleracea group), although they caused severe symptoms on their original host species. In contrast, cabbage isolates had significantly higher (P = 0.05) virulence on B. oleracea than on B. rapa crops. Our results indicate that F. oxysporum complex isolates from B. rapa and B. oleracea are not only phylogenetically distinct but also differ in host specificity. Therefore, we propose a novel forma specialis, F. oxysporum f. sp. rapae, which causes yellows on B. rapa, including turnip, komatsuna, pak choi, and narinosa.

    O MIRAX (Monitor e Imageador de RAios-X) é um projeto de desenvolvimento de um pequeno satélite astronômico de raios-X (~200 kg, ~240 W). A estratégia básica da missão será observar continuamente (~9 meses por ano) a região central (~1000 graus2) do plano Galáctico e realizar estudos espectroscópicos de banda larga (2-200 keV) e alta sensibilidade de um grande conjunto de fontes através de imagens com resolução de ~6'. Isso proporcionará uma cobertura inédita do "espaço de descobertas" através da detecção, localização, identificação e estudo detalhado de fenômenos imprevisíveis, tais como transientes fracos de raios-X, novas rápidas de raios-X e bursts de raios gama, assim como o estudo de fontes com emissão persistente. Neste trabalho apresentamos o projeto das duas câmeras de raios-X duros (CXDs) do MIRAX, que irão operar na faixa de 10 a 200 keV. Cada CXD consistirá de um plano de detectores CZT (Cd0,9Zn0,1Te) de 0,5 mm de resolução espacial e 370 cm2 de área total, e de uma máscara codificada com elementos quadrados de 1,3 mm de lado e 0,5 cm de espessura. A máscara terá dimensões de 315 cm ´ 275 cm e será montada a 700 cm de distância dos detectores. Com essa configuração as CXDs terão 6' de resolução angular e, quando colocadas a um ângulo de 29° entre si, as duas câmeras propiciam um campo totalmente codificado de 39° ´ 6°12' e um campo total de 76° ´ 44°. Serão apresentadas simulações de observações da região do plano Galáctico com o conjunto formado pelas duas CXDs.

    Since 2007 the ITER-INVOLCAN/UNICV-OVCV/SNPC research team has implemented a geochemical program for the volcanic surveillance of Fogo volcano by means of applying different geochemical methods in a regularly basis (diffuse degassing surveys, fumarole gas sampling, etc.). This program was improved by setting up a geochemical permanent station (CHA01) to perform continuous measurements of soil gas radon (222Rn) and thoron (220Rn) activities at Chã das Caldeiras, more specific in Portela village, since April 20, 2013. Both gases are characterized to ascend towards the surface mainly through cracks or faults via diffusion and/or advection mechanisms dependent of both soil porosity and permeability, which in turn vary as a function of the stress/strain changes at depth. Measurements of 222Rn and 220Rn activities were performed by an alpha-spectrometer after pumping the soil gas from a thermally isolated PVC pipe inserted 1m in the ground. Even though during the study period the recorded data did not show high 222Rn activity values, a change in the temporal evolution of soil gas 222Rn activity was observed. During the first six months, from April to October, 2013, recorded time series of 222Rn and 220Rn activities showed normal background levels with values of 80.5 and 55.2 Bqm-3, respectively. However, from October, 2013, to February, 2014, 222Rn time series showed an increase trend reaching peak values of 396 Bqm-3 and having an average activity of 134 Bqm-3 until the removal of the station on November 25, 2014 due to the potential danger of being destroyed by the lava flows. The observed increase in the soil gas 222Rn activity from October 2013 to February 2014 occurs almost at the same time of slight observed changes in the vertical displacements detected by the geodetic network installed at the Fogo Island by the ITER-INVOLCAN/UNICV-OVCV/SNPC/Nagoya University research team. Since seismic data are not available, we cannot conclude if the observed changes in soil

    This paper presents a case study on the prospects of bathing in a large water course (das Velhas River, Brazil), which crosses the important metropolitan region of Belo Horizonte (25 municipalities), receiving several point and diffuse discharges. The studies were carried out based on a mathematical simulation of thermotolerant coliforms over 227 km of the river, using an adaptation of the Qual2E model (model Qual-UFMG). Simulations of intervention scenarios were made for the current conditions, with three reference flows for the das Velhas River, tributaries and direct contribution: Q7,10 (representative of low-flow conditions), Q50 (average conditions) and Q10 (rainy season). The intervention scenarios simulated were: (a) current conditions without intervention; (b) scenario with effluent disinfection in the two largest wastewater treatment plants in the basin (around 2.4 million inhabitants); (c) scenario with 95% sewage collection and treatment, with disinfection in all municipalities of the study area; (d) scenario with the calculation of values required for the coverage of sewage treatment and coliform removal efficiencies based on a mathematical optimization process. The monitoring data and results of all simulations indicated improvement in coliform concentration as the river flows downstream. However, results suggested that disinfection per se is not enough. Even under hypothetical conditions of excellent sanitary infrastructure for a developing country, coverage of collection and treatment of 95% of the generated sewage, and treatment with disinfection at all wastewater treatment plants, concentrations of thermotolerant coliforms in das Velhas River are likely to be above the maximum allowable of 1,000 MPN/100 mL for bathing purposes. The mathematical optimization indicated the need for very high percentages of sewage treatment coverage (near 100%, i.e. universality of collection and treatment) and implementation of disinfection in most treatment plants

    The Jesuit Missions the Guaranis were one of the great examples of cultural, social, and scientific of the eighteenth century, which had its decline from successive wars that followed the exchange of territories domain occupied by Portugal and Spain with the Madrid Treaty of January 13, 1750. One of the great examples of this development is materialized in the ruins of 30 churches and villages that remain in a territory that now comprises part of Brazil, Argentina and Paraguay. These Churches, São Miguel das Missões is among the Brazilian ruins, the best preserved. The ruins of São Miguel das Missões were declared a UNESCO World Cultural Heritage in 1983 and the Institute of National Historical Heritage (IPHAN) is the Brazilian Federal agency that manages and maintains this heritage. In order to produce a geographic database to assist the IPHAN in the management of the Ruins of São Miguel das Missões it was proposed a three-dimensional mapping of these ruins never performed in this location before. The proposal is integrated data acquired from multiple sensors: two micro-UAV, an Asctec Falcon 8 (rotary wing) and a Sensefly e-Bee (fixed wing); photos from terrestrial cameras; two terrestrial LIDAR sensors, one Faro Focus 3D S-120 and Optec 3D-HD ILRIS. With this abundance of sensors has been possible to perform comparisons and integration of the acquired data, and produce a 3D reconstruction of the church with high completeness and accuracy (better than 25 mm), as can be seen in the presentation of this work.

    Data assimilation has become a popular method to integrate observations from multiple sources with land surface models to improve predictions of the water and energy cycles of the soil-vegetation-atmosphere continuum. Multivariate data assimilation refers to the simultaneous assimilation of observation data from multiple model state variables into a simulation model. In recent years, several land data assimilation systems have been developed in different research agencies. Because of the software availability or adaptability, these systems are not easy to apply for the purpose of multivariate land data assimilation research. We developed an open source multivariate land data assimilation framework (DasPy) which is implemented using the Python script language mixed with the C++ and Fortran programming languages. LETKF (Local Ensemble Transform Kalman Filter) is implemented as the main data assimilation algorithm, and uncertainties in the data assimilation can be introduced by perturbed atmospheric forcing data, and represented by perturbed soil and vegetation parameters and model initial conditions. The Community Land Model (CLM) was integrated as the model operator. The implementation allows also parameter estimation (soil properties and/or leaf area index) on the basis of the joint state and parameter estimation approach. The Community Microwave Emission Modelling platform (CMEM), COsmic-ray Soil Moisture Interaction Code (COSMIC) and the Two-Source Formulation (TSF) were integrated as observation operators for the assimilation of L-band passive microwave, cosmic-ray soil moisture probe and land surface temperature measurements, respectively. DasPy has been evaluated in several assimilation studies of neutron count intensity (soil moisture), L-band brightness temperature and land surface temperature. DasPy is parallelized using the hybrid Message Passing Interface and Open Multi-Processing techniques. All the input and output data flows are organized efficiently

    A novel multiplex PCR method was developed for simultaneous event-specific detection of four events of GM maize, i.e., DAS-59122-7, MIR604, MON88017, and MON863. The single laboratory examination of analytical performance using simulated DNA mixtures containing GM DNA at various concentrations in non-GM DNA suggested that the limits of detection (LOD) of the multiplex PCR method were 0.16% for MON863, MIR604, and MON88017, and 0.078% for DAS-59122-7. We previously developed a nonaplex (9plex) PCR method for eight events of GM maize, i.e., Bt11, Bt176, GA21, MON810, MON863, NK603, T25, and TC1507. Together with the nonaplex PCR method, the newly developed method enabled the detection and identification of eleven GM maize events that are frequently included in commercial GM seed used in Japan. In addition, this combinational analysis may be useful for the identification of combined event products of GM maize. PMID:20595789

    RESUMEN EJECUTIVO El impulso para desarrollar e implementar estrategias de medicina integrativa está enraizado en el deseo de mejorar la atención al paciente. The Bravewell Collaborative, una organización sin ánimo de lucro dedicada a la mejora de la atención sanitaria, define la medicina integrativa como “un enfoque de la medicina que coloca al paciente en el centro y se dirige al conjunto completo de influencias físicas, emocionales, mentales, sociales, espirituales y ambientales que afectan a la salud de la persona. Con una estrategia personalizada que considera las condiciones, necesidades y circunstancias únicas del paciente, utiliza las intervenciones más apropiadas de una variedad de disciplinas científicas para curar la afección y la enfermedad y ayudar a las personas a recobrar y mantener una salud óptima”. En las pasadas dos décadas, se ha documentado un número creciente de centros clínicos que proporcionan medicina integrativa, el número de facultades y escuelas médicas que enseñan estrategias integrativas, el número de investigadores que estudian intervenciones integrativas, y el número de pacientes que solicitan cuidados integrativos. Pero se desconocía si la medicina integrativa se estaba ofreciendo de manera igual, similar, o dispar. Además, mientras que los estudios anteriores se centraban en la prevalencia y el uso de la medicina complementaria o alternativa (MCA) por parte de los pacientes1,2 o de los médicos en hospitales3, enumerando la utilización de terapias MCA individuales, se había recogido muy poca información con respecto a la práctica real de la medicina integrativa que, por definición, trata a la persona en su conjunto. En 2011, The Bravewell Collaborative encargó una encuesta para determinar la forma en que la medicina integrativa se estaba practicando en los Estados Unidos: (1) describiendo las poblaciones de pacientes y las afecciones sanitarias tratadas más habitualmente; (2) definiendo las pr

    The stigma of nasal deformity due to a congenital cleft lip-palate has an undeniable influence on the affected patient's life. It is therefore of interest to investigate if efforts to reduce esthetic and functional impairments by rhinoplasty (single or multiple) can result in an increased satisfaction with appearance and a self-perception similar to the noncleft population. Retrospective scoring before and after rhinoplasty using the validated Derriford Appearance Scale (DAS-59) and subsequent statistical evaluation and comparison to datasets available in the literature for further classification was used. Of the 61 patients who underwent at least one rhinoplasty, 26 responded to all questions. The mean age of responders was approximately 30 years of age and the male:female ratio was 1:1.2. The scale showed a significant overall improvement after surgery. The full scale and all subscale scores of the DAS-59 were significantly reduced after surgery demonstrating an improvement in the respective categories. Most importantly, if postoperative results were compared with a population concerned and unconcerned about appearance, no difference "facial self-consciousness" of appearance was apparent. Also postoperative subscores for "general self-consciousness" (GSC) and "social self-consciousness" of appearance (SSC) showed no difference from those obtained from the population concerned about appearance. The postoperative subscore for "sexual and bodily self-consciousness" of appearance (SBSC) indicated improvement beyond the level found in the concerned control population. Due to only a low improvement in the difference compared with the subscore representing a "negative self-concept," a statistically significant difference to the concerned population remained, possibly indicating that therapy beyond surgery is needed for improvement. After rhinoplasty, the investigated group of cleft lip-palate patients with nasal deformities showed an improvement in their self

    Excavation of Toca do Serrote das Moendas, in Piauí state, Brazil revealed a great quantity of fossil wild fauna associated with human remains. In particular, fossils of a cervid (Blastocerus dichotomus) were found, an animal frequently pictured in ancient rock wall paintings. In a well-defined stratum, two loose teeth of this species were found in close proximity to human bones. The teeth were independently dated by electron spin resonance (ESR) in two laboratories. The ages obtained for the teeth were 29 ± 3 ka (thousands of years) and 24 ± 1 ka. The concretion layer capping this stratum was dated by optically stimulated luminescence (OSL) of the quartz grains to 21 ± 3 ka. As these values were derived independently in three different laboratories, using different methods and equipment, these results are compelling evidence of early habitation in this area.

    A wide submarine seep of thermogenic gas in the Katakolo bay, Western Greece, was monitored passively using the intelligent Distributed Acoustic Sensor (iDAS) and Ultima Raman spectra Distributed Temperature Sensor (DTS), in order to study the thermal and noise signal of the bubble plumes released from the seafloor. Katakolo is one one of the most prolific thermogenic gas seepage zones in Europe and the biggest methane seep ever reported in Greece. Very detailed repetitive offshore gas surveys, including marine remote sensing (sub-bottom profiling, side scan sonar), underwater exploration by a towed instrumented system (MEDUSA), long-term monitoring benthic station (GMM), compositional and isotopic analyses, and flux measurements of gas, showed that: (a) gas seepage takes place over an extended area in the Katakolo harbour and along two main normal faults off the harbour; (b) at least 823 gas bubble ( 10-20 cm in diameter) plumes escaping over an area of 94,200 m2, at depths ranging from 5.5 to 16 m; (c) the gas consists mainly of methane and has H2S levels of hundreds to thousands ppmv, and shows significant amounts of other light hydrocarbons like ethane, propane, iso-butane and C6 alkanes, (d) offshore and onshore seeps release the same type of thermogenic gas; (e) due to the shallow depth, more than 90 % of CH4 released at the seabed enters the atmosphere, and (f) the gas seeps may produce severe geohazards for people, buildings and construction facilities due to the explosive and toxicological properties of methane and hydrogen sulfide, respectively. For the short-term monitoring, the deployment took place on a site located inside the harbour of Katakolo within a thermogenic gas seepage area where active faults are intersected. The iDAS system makes it possible to observe the acoustical signal along the entire length of an unmodified optical cable without introducing any form of point sensors such as Bragg gratings.

    Natural convection in a square porous cavity filled with a nanofluid in conditions of thermal stratification has been numerically studied. The mathematical model has been formulated in terms of the dimensionless stream function and temperature using the Darcy-Boussinesq approximation and Tiwari and Das' nanofluid model with new more realistic empirical correlations for the physical properties of the nanofluids. Formulated partial differential equations along with the corresponding boundary conditions have been solved by the finite difference method. Particular efforts have been focused on the effects of the Rayleigh number, thermal stratification parameter, porosity of the porous medium, solid volume fraction parameter of nanoparticles, and the solid matrix of the porous medium (glass balls and aluminum foam) on the local and average Nusselt numbers, streamlines and isotherms. It has been observed an essential effect of thermal stratification parameter on heat and fluid flow fields.

    Understanding groundwater flow and contaminant transport in fractured bedrock aquifers requires detailed characterization of the discrete features that control flow, as well as the properties of the rock matrix. This requires multiple, high-resolution, depth discrete datasets that provide different, but complementary information. Distributed fibre optic sensing is a relatively new technology used to continuously monitor properties along the entire length of an optical fibre. Technological advances over the past few years have brought the sensitivity and spatial resolution to the point where shallow (<200m) borehole applications are practicable. Recent studies using fibre optic distributed temperature sensors (DTS) have shown excellent application of DTS for characterizing groundwater flow in both continuously sealed and open boreholes. This presentation highlights the results of a field trial at the Bedrock Aquifer Research Station on the University of Guelph campus (Ontario, Canada) where a single fibre optic cable was interrogated by both a DTS (Ultima-DTS) and a Distributed Acoustic Sensor (iDAS). DAS is a relatively recent development that allows an optical fibre to be used as a receiver for seismic imaging. These seismic images are produced by sending an optical pulse down the fibre and analyzing the effects of seismic waves on the propagating light. Numerous vertical seismic profiles were collected and the effects of different fibre optic cable structures and coupling techniques were examined. The seismic profiles will help delineate structural features and lithological contacts away from the borehole wall, and will assist in correlating other geophysical, hydraulic, or geological logs collected in the boreholes across the site. Preliminary results show promise for shallow seismic imaging and continued field trials will allow refinement of the technique.

    The overexpression of dihydroxyacetone synthase (DAS) and dihydroxyacetone kinase (DAK) from methylotrophic yeasts in chloroplasts created a photosynthetic formaldehyde (HCHO)-assimilation pathway (DAS/DAK pathway) in transgenic tobacco. Geranium has abilities to absorb and metabolize HCHO. Results of this study showed that the installed DAS/DAK pathway functioning in chloroplasts greatly enhanced the role of the Calvin cycle in transgenic geranium under high concentrations of gaseous HCHO stress. Consequently, the yield of sugars from HCHO-assimilation increased approximately 6-fold in transgenic geranium leaves, and concomitantly, the role of three original HCHO metabolic pathways reduced, leading to a significant decrease in formic acid, citrate and glycine production from HCHO metabolism. Although the role of three metabolic pathways reduced in transgenic plants under high concentrations of gaseous HCHO stress, the installed DAS/DAK pathway could still function together with the original HCHO metabolic pathways. Consequently, the gaseous HCHO-resistance of transgenic plants was significantly improved, and the generation of H2O2 in the transgenic geranium leaves was significantly less than that in the wild type (WT) leaves. Under environmental-polluted gaseous HCHO stress for a long duration, the stomata conductance of transgenic plants remained approximately 2-fold higher than that of the WT, thereby increasing its ability to purify gaseous HCHO polluted environment.

    In this study new SHRIMP U-Pb zircon data for the Chácara das Pedras Gneiss in Porto Alegre, southern Brazil are presented. They represent a small exposure of the crust which was intruded by a large volume of orogenic to anorogenic granitoids at ca. 618-562 m.y. in the Eastern Domain of the Dom Feliciano Belt. The Chácara das Pedras tonalitic orthogneiss has geochemical similarities with subduction-related magmatic rocks of continental arcs. They present high Sr initial ratios (∼0.712), negative ɛNd(t = 777) values (∼-6), TDM varying from 1.8 to 2.0 Ga. The igneous protoliths of these orthogneisses were previously considered to be Paleoproterozoic based on an upper intercept age of discordant zircon analyses. In the present study these orthogneisses were re-sampled and re-analyzed in an attempt to obtain more concordant analytical data. The U-Pb zircon analyses were carried out using the SHRIMP IIe at the Laboratório de Geocronologia de Alta Resolução of the Universidade de São Paulo. The U-Pb concordia age obtained for igneous textural domains of the zircon grains is 777 ± 4 Ma. A few analyses on zircon overgrowths give poorly defined late Cryogenian ages of ca. 650 Ma. Older ages, mostly discordant, were obtained in a few zircon cores, showing an upper intercept age of ca. 1.9 Ga. One sample of the Três Figueiras Granodiorite, which crosscut the orthogneiss in the same outcrop, was also investigated. The zircons of this granodiorite are, however, mostly metamitic, preventing the determination of a reliable age. Some concordant analyses from a few grains define ages ranging in the interval between ca. 603 and 1022 Ma. The youngest (ca. 603 Ma) may represent a maximum age for the granodiorite crystallization. Older ages, with discordance <10%, are of 745, 777, 836 and 1022 Ma. The 777 ± 4 Ma age obtained for the Chácara das Pedras orthogneiss is the first Early Cryogenian magmatic age determined for granitoids in the Porto Alegre region, although

    Southeastern Brazil is under a period of drought that has impacted the conservation of watersheds and the management of water quality and quantity for agricultural and urban demands. In this context agro-hydrological modeling tools can generate information of water response over time in response to climate and landuse changes. A 12-km2 watershed which has suffered from anthropogenic activities is the Ribeirão das Posses watershed that is located in the extreme south of Minas Gerais State and is a headwater catchment of the Jaguari river, one of the contributing rivers of the Cantareira Reservoir Complex in the state of São Paulo. This watershed had its landscape changed over the last century from native forests to more homogeneous vegetation for pastures and small crops and some forest plantations fragments with eucalyptus. Currently, the Conservative Waters project has planted some small areas with vegetation of native species, especially where there are springs and at the top of the hills, in order to recover degraded areas and improve the hydrogeochemistry in this study basin. In this context, the AgroEcoSystem-Watershed (AgES-W) model is presented to simulate the water movement and storage in agricultural watersheds with different spatial resolutions of land areas or hydrological responses units. The objectives are to evaluate the quality and quantity of water in Ribeirão das Posses Basin using measured data, then simulate these responses in space and time to test the AgES-W model. The period chosen for research was from 2011 to 2015, because the water quality data were collected during this period. The answers that we hope to find out are: How well does the AgES-W model simulate this Brazilian watershed in the tropics? What are the future prospects of the quality and quantity of water in this basin? The results will help to guide hydrological simulations in similar tropical environments in Brazil in this and other agricultural watersheds with AgES-W.

    Batch tests and diffusion tests were performed to analyze the efficiency of a protective barrier in a landfill consisting of compacted soil with 10% bentonite compared to the results obtained for only compacted soil and for compacted soil covered with a 1-mm-thick HDPE geomembrane; the soil and leachate were collected from the Rio das Ostras Landfill in Rio de Janeiro, Brazil. The diffusion tests were performed for periods of 3, 10 and 60 days. After the test period, the soil pore water was analyzed and the profiles for chloride, potassium and ammonium were determined along a 6-cm soil depth. The results of the batch tests performed to define sorption parameters were used to adjust the profiles obtained in the diffusion cell experiment by applying an ion transfer model between the interstitial solution and the soil particles. The MPHMTP model (Multi Phase Heat and Mass Transfer Program), which is based upon the solution of the transport equations of the ionic contaminants, was used to solve the inverse problem of simultaneously determining the effective diffusion coefficients. The results of the experimental tests and of the model simulation confirmed that the compacted soil with 10% bentonite was moderately efficient in the retention of chloride, potassium and ammonium ions compared to the configurations of compacted soil with a geomembrane and compacted soil alone, representing a solution that is technically feasible and requires potentially lower costs for implementation in landfills.

    The aim of the study was to study the prevalence of juvenile idiopathic arthritis (JIA) in school children in the city of Embu das Artes in São Paulo State. 2880 school children from seven public schools, aged between 6 and 12 years, were evaluated (clinical findings) by a pediatric rheumatologist. A board certified Pediatric Rheumatologist evaluated the subjects with suspected inflammatory arthropathy. Children with higher suspicion were referred to a specialized service. One hundred and forty-one children have presented abnormalities on examination of musculoskeletal system, with isolated pain on palpation the most common finding in the first evaluation (60.9%), with improvement in almost all cases in the second examination. Most of the abnormalities were related to recent injuries or congenital malformations. Six children have clinical findings suggestive of chronic arthropathy and were referred to a specialized pediatric rheumatology clinic. Of these, a 12 year-old girl fulfilled the criteria for JIA. The other diagnoses were aseptic necrosis of the hip (P = 1) of and post-trauma synovitis (P = 4). The prevalence of JIA in children aged between 6 and 12 years was 1/2.880 (or 0.34/1.000).

    The Poço das Antas National Biological Reserve is located in Rio de Janeiro State, southeast Brazil. This paper presents information on past environmental characteristics of the area through pollen analysis. Two sedimentary columns were collected and five samples were selected for radiocarbon dating. The following ages of the columns from bottom to top were detected: column 1 - 1.20-1.16 m: 6080 +/-40 years BP, 0.775-0.735 m: 4090 +/-40 years BP, 0.385-0.345 m: 1880 +/-80 years BP; column 2 - 1.22-1.18 m: 3520 +/-40 years BP, 0.23-0.19 m: 1810 +/-40 years BP. Three samples from column 1 and two samples from column 2 were selected for pollen analysis: 1.20 m, 0.77 m and 0.37 m of column 1 and 1.22 m and 0.21 m of column 2. Chemical treatment followed standard methodology. The palynological analysis shows that around 6080 years BP the study area was dominated by a rain forest and from around 4090 years BP the vegetation changed to a fragmented forest, restricted to low hills and surrounded by an open area of grassland and pioneer plants, swamps and peat areas. The pollen assemblage of the samples 3520, 1880 and 1810 years BP suggest the permanence of this kind of vegetation between 4000 years BP and the actual.

    This work reports the dating of a fossil human tooth and shell found at the archaeological site Toca do Enoque located in Serra das Confusões National Park (Piauí, Brazil). Many prehistoric paintings have been found at this site. An archaeological excavation unearthed three sepulchers with human skeletons and some shells. Two Brazilian laboratories, in Ribeirão Preto (USP) and Recife (UFPE), independently performed Electron Spin Resonance (ESR) measurements to date the tooth and the shell and obtain the equivalent dose received by each sample. The laboratories determined similar ages for the tooth and the shell (~4.8 kyBP). The results agreed with C-14 dating of the shell and other samples (charcoal) collected in the same sepulcher. Therefore, this work provides a valid inter-comparison of results by two independent ESR-dating laboratories and between two dating methods; i.e., C-14 and ESR, showing the validity of ESR dating for this range of ages.

    O High Energy Transient Explorer (HETE) é o primeiro satélite inteiramente dedicado ao estudo das explosões cósmicas de raios gama (ECRGs). Lançado em 9 de outubro de 2000, o HETE possui instrumentação capaz de observar as ECRGs desde o UV até raios gama e localizá-las com precisão de ~ 1-10 minutos de arco. As localizações das ECRGs detectadas são disseminadas rapidamente (em alguns segundos) pela Internet através de uma rede de estações de recepção ao longo do equador. A participação brasileira nesse projeto se dá através da montagem e operação de uma estação de recepção em Natal, RN, e da participação na equipe científica da missão. Neste trabalho são apresentados resultados da observação pelo HETE de duas ECRGs: GRB 021004 e GRB 021211. A GRB021004 foi detectada em raios gama pelo HETE em 4 de outubro de 2002 e localizada em raios-X em apenas 48 s, quando a emissão de raios gama ainda estava se processando. A explosão, relativamente brilhante e longa, durou aproximadamente 100 s. Um transiente óptico de magnitude 15 foi detectado no local da explosão nove minutos após o evento, e observações realizadas após 7 horas determinaram um desvio para o vermelho de absorção de 1,6. O GRB021004 foi o burst mais bem observado até o momento e suas observações em vários comprimentos de onda têm sido fundamentais para o aprimoramento dos modelos de ECRGs. O GRB21211, um burst brilhante e rico em raios-X, foi detectado em 11 de dezembro de 2002 e localizado em raios-X em 22 s após o início do evento. A duração do burst foi de 2,3 s em altas energias (85 a 400 keV) e de 8,5 s em baixas energias (2 a 10 keV). Caso essa explosão não tivesse sido rapidamente localizada pelo HETE, ela teria sido classificada como "opticamente escura", já que o transiente óptico decaiu rapidamente de R < 14 a R»19 dentro dos primeiros 20 minutos e já estava mais fraco do que R»23 depois de 24 horas da ocorrência do burst.

    The Morro Velho gold deposit, Quadrilátero Ferrífero region, Minas Gerais, Brazil, is hosted by rocks at the base of the Archean Rio das Velhas greenstone belt. The deposit occurs within a thick carbonaceous phyllite package, containing intercalations of felsic and intermediate volcaniclastic rocks and dolomites. Considering the temporal and spatial association of the deposit with the Rio das Velhas orogeny, and location in close proximity to a major NNW-trending fault zone, it can be classified as an orogenic gold deposit. Hydrothermal activity was characterized by intense enrichment in alteration zones of carbonates, sulfides, chlorite, white mica±biotite, albite and quartz, as described in other Archean lode-type gold ores. Two types of ore occur in the deposit: dark gray quartz veins and sulfide-rich gold orebodies. The sulfide-rich orebodies range from disseminated concentrations of sulfide minerals to massive sulfide bodies. The sulfide assemblage comprises (by volume), on average, 74% pyrrhotite, 17% arsenopyrite, 8% pyrite and 1% chalcopyrite. The orebodies have a long axis parallel to the local stretching lineation, with continuity down the plunge of fold axis for at least 4.8 km. The group of rocks hosting the Morro Velho gold mineralization is locally referred to as lapa seca. These were isoclinally folded and metamorphosed prior to gold mineralization. The lapa seca and the orebodies it hosts are distributed in five main tight folds related to F1 (the best examples are the X, Main and South orebodies, in level 25), which are disrupted by NE- to E-striking shear zones. Textural features indicate that the sulfide mineralization postdated regional peak metamorphism, and that the massive sulfide ore has subsequently been neither metamorphosed nor deformed. Lead isotope ratios indicate a model age of 2.82 ± 0.05 Ga for both sulfide and gold mineralization. The lapa seca are interpreted as the results of a pre-gold alteration process and may be

    Wir schlagen ein neues Modell zur Beschreibung der in der Nähe der Oberfläche von Kryodielektrika lokalisierten Elektronenzustände vor. Dabei wird die Nichteindeutigkeit der selbstadjungierten Erweiterung des Hamilton-Operators der elektrostatischen Bildkräfte an der flachen Grenze Dielektrikum-Vakuum benutzt. Im Unterschied zum bekannten Modell von Grimes enthält das von uns vorgeschlagene Modell nur einen einzigen phänomenologischen Parameter, den Vermischungswinkel. Es zeigt sich, daß die entsprechende Wahl des Vermischungswinkels es erlaubt, die spektroskopischen Daten von elektrischen Dipolübergängen zwischen den Einteilchen-Elektronenzuständen, die über der Oberfläche flüssigen 4He und 3He sowie festen Wasserstoffe lokalisiert sind, vollständig zu beschreiben.Translated AbstractA Singular Model of Electronic States, Localized over the Surface of Cryogenized DielectricA new model for the description of localized electronic states near the surface of a cryogenized dielectric is proposed. In this model an ambiguity of the self-adjoined extention of the Hamiltonian for the problem of the motion of an electron in the field of the electrostatic image at flat boundary dielectric-vacuum is used. The proposed model, in contrast with the well known model of Grimes, contains as only phenomenological parameter the mixing angle. It is shown that the proper choise of the mixing angle makes it possible to completely account for the spectroscopic data on electric dipole transitions between singleparticle electronic states localized over the surfaces of 4He, 3He and also solid hydrogen.

    Linepithema humile (Mayr), the Argentine ant, is an invasive pest that has spread throughout the United States and is a problem in natural and managed habitats in South Carolina. Foraging patterns and the effectiveness of liquid baits for control of this pest have been studied in urban areas. However, similar studies have not been conducted in natural areas such as parks, picnic grounds, or campsites. L. humile populations can be large and widespread, making them a major nuisance pest for visitors to these natural areas. The primary objective of this study was to determine an effective distance between bait stations for control of L. humile in a natural area. A double antibody-sandwich enzyme-linked immunosorbent assay (DAS-ELISA) procedure was used to detect individual ants that consumed rabbit immunoglobin (IgG) protein for marking and tracking. In both lab and field conditions, there was a significant difference in the detection of IgG in ants fed protein marker mixed with sugar water compared with ants only fed sugar water. Additional field studies revealed that an individual ant could retain detectable levels of protein marker for 3 d and that an ant feeding on IgG containing bait could be detected over 15 m from the original bait source. Overall, we found that using liquid ant baits, with a placement of 20 m between stations, was effective in reducing L. humile numbers between April to October, 2012 in a natural park area of Lake Greenwood State Park, SC.

    Orogenic, gold deposits are hosted by rocks of the Archean Rio das Velhas greenstone belt in the Quadrilátero Ferrífero region, Minas Gerais state, Brazil, one of the major gold provinces in the world. The gold deposits occur at the base of the mafic-ultramafic succession, with the most important orebodies controlled by E-W-striking, strike-slip faults. The main mineralization styles are (1) structurally controlled, sulfide replacement zones in banded iron formation (BIF); (2) disseminated sulfide minerals and gold in hydrothermally altered rocks along shear zones; and (3) auriferous quartz-carbonate-sulfide veins and veinlets in mafic, ultramafic, and felsic volcanic rocks, and also in clastic sedimentary rocks. The most common host rocks for ore are metamorphosed oxide- and carbonate-facies banded iron (± iron-rich metachert) formations (e.g., the Cuiabá, São Bento and Raposos deposits) and the lapa seca unit, which is a local term for intensely carbonatized rock (e.g., the giant Morro Velho mine with >450 t of contained gold). Metabasalts host most of the remaining gold deposits. Mineralogical characteristics and fluid inclusion studies suggest variations in the H2O/CO2 ratio of a low-salinity, near-neutral, reducing, sulfur-bearing, ore fluid. The presence of abundant CH4-rich inclusions is related to reduction of the original H2O-CO2 fluid via interaction with carbonaceous matter in the wallrocks. Oxygen fugacity was close to that of graphite saturation, with variations likely to have been influenced by reaction with the carbonaceous matter. Carbon-rich phyllites and schists, which commonly bound ore-bearing horizons, seem to have played both a physical and chemical role in localizing hydrothermal mineral deposition. Microtextural studies indicate that gold deposition was mainly related to desulfidation reactions, and was paragenetically coeval with precipitation of arsenic-rich iron sulfide minerals. Carbon isotope data are compatible with dissolution of

    1999-11-01

    Mit der vorliegenden Arbeit werden exemplarisch Chancen und Grenzen der Integration von Umwelt- und Naturschutz in Verfahren der ackerbaulichen Landnutzung aufgezeigt. Die Umsetzung von Zielen des Umwelt- und Naturschutzes in Verfahren der Landnutzung ist mit verschiedenen Schwierigkeiten verbunden. Diese liegen zum einen in der Konkretisierung der Ziele, um diese umsetzen zu können, zum anderen in vielfach unzulänglichem Wissen über den Zusammenhang zwischen unterschiedlichen Formen der Landnutzung und insbesondere den biotischen Naturschutzzielen. Zunächst wird die Problematik der Zielfestlegung und Konkretisierung erörtert. Das Umweltqualitätszielkonzept von Fürst et al. (1992) stellt einen Versuch dar, Ziele des Umwelt- und Naturschutzes zu konkretisieren. Dieses Konzept haben Heidt et al. (1997) auf einen Landschaftsausschnitt von ca. 6000 ha im Biosphärenreservat Schorfheide-Chorin im Nordosten Brandenburgs angewendet. Eine Auswahl der von Heidt et al. (1997) formulierten Umweltqualitätsziele bildet die Basis dieser Arbeit. Für die ausgewählten Umweltqualitätsziele wurden wesentliche Einflussfaktoren der Landnutzung identifiziert und ein Bewertungssystem entwickelt, mit dem die Auswirkungen von landwirtschaftlichen Anbauverfahren auf diese Umweltqualitätsziele abgebildet werden können. Die praktizierte Landnutzung von 20 Betrieben im Biosphärenreservat Schorfheide-Chorin wurde von 1994 bis 1997 hinsichtlich ihrer Auswirkungen auf die Umweltqualitätsziele analysiert.

    The pandemic novel influenza A (H1N1) infection was considered widespread in Brazil on July 16, 2009. Since then, 46,810 cases of acute respiratory syndrome have been reported in Brazil, most of them concentrated in São Paulo. Through September 16, we have confirmed 9,249 cases of novel influenza A H1N1in Brazil, including 699 deaths. The mortality rate observed in Brazil is 0.47/100,000 inhabitants and varies according to region. In this period, São Paulo registered 3733 cases (40.3% of the total) of novel influenza A (H1N1) infection and 327 deaths, reflecting a mortality rate of 0.79/100,000 inhabitants. The Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC) is a reference center for H1N1 cases in São Paulo. During the winter of 2009, 472 patients in this hospital were diagnosed with H1N1 infection; of these, 210 were admitted, and 16 died. To control this pandemic and to provide adequate care for these patients, the Hospital das Clínicas implemented “bundles” including prevention strategies, an epidemiologic surveillance service, availability of fast diagnosis, antiviral treatment and training of staff. The purpose of this manuscript is to describe the epidemiologic features of novel human influenza A (H1N1) infection in the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo during the winter period of the 2009 pandemic.

    Introducción: la razón de muerte materna (RMM) ha disminuido lentamente, no obstante que la OMS se propuso reducirla en un 75 % en el período de 1990 a 2015. Por esto es necesario continuar con el análisis de las causas para reforzar e innovar líneas de acción y así disminuir las muertes maternas en nuestro país. Métodos: estudio retrospectivo en el que se incluyeron casos de muerte materna que ocurrieron de 2009 a 2012, por causa directa e indirecta. La información se obtuvo del expediente de muerte materna, el cual es un documento oficial del IMSS. La definición de muerte materna utilizada fue la emitida por la OMS. Las muertes indirectas se agruparon según la décima revisión de la Clasificación Internacional de Enfermedades (CIE-10). Se utilizó estadística descriptiva. Resultados: la RMM en el IMSS ha disminuido en forma lenta pero constante, pues en el 2012 se obtuvo la RMM más baja en la institución (26.4). Sin embargo, la preeclampsia severa-eclampsia y la hemorragia obstétrica ocuparon el primero y segundo lugar. Como causa indirecta, las enfermedades del sistema cardiovascular, y las neoplasias malignas ocuparon los primeros lugares sin subestimar las cifras de las patologías respiratorias, digestivas y endocrinas. Conclusiones: es necesario proseguir con los esfuerzos para disminuir la RMM en todos los niveles de atención médica. Es prioritario continuar con la educación y consejería preconcepcional a mujeres en edad fértil y fortalecer las acciones en la planificación familiar.

    The cosmopolitan fungal genus Alternaria consists of multiple saprophytic and pathogenic species. Based on phylogenetic and morphological studies, the genus is currently divided into 26 sections. Alternaria sect. Alternaria contains most of the small-spored Alternaria species with concatenated conidia, including important plant, human and postharvest pathogens. Species within sect. Alternaria have been mostly described based on morphology and / or host-specificity, yet molecular variation between them is minimal. To investigate whether the described morphospecies within sect. Alternaria are supported by molecular data, whole-genome sequencing of nine Alternaria morphospecies supplemented with transcriptome sequencing of 12 Alternaria morphospecies as well as multi-gene sequencing of 168 Alternaria isolates was performed. The assembled genomes ranged in size from 33.3–35.2 Mb within sect. Alternaria and from 32.0–39.1 Mb for all Alternaria genomes. The number of repetitive sequences differed significantly between the different Alternaria genomes; ranging from 1.4–16.5 %. The repeat content within sect. Alternaria was relatively low with only 1.4–2.7 % of repeats. Whole-genome alignments revealed 96.7–98.2 % genome identity between sect. Alternaria isolates, compared to 85.1–89.3 % genome identity for isolates from other sections to the A. alternata reference genome. Similarly, 1.4–2.8 % and 0.8–1.8 % single nucleotide polymorphisms (SNPs) were observed in genomic and transcriptomic sequences, respectively, between isolates from sect. Alternaria, while the percentage of SNPs found in isolates from different sections compared to the A. alternata reference genome was considerably higher; 8.0–10.3 % and 6.1–8.5 %. The topology of a phylogenetic tree based on the whole-genome and transcriptome reads was congruent with multi-gene phylogenies based on commonly used gene regions. Based on the genome and transcriptome data, a set of core proteins was extracted, and primers were designed on two gene regions with a relatively low degree of conservation within sect. Alternaria (96.8 and 97.3 % conservation). Their potential discriminatory power within sect. Alternaria was tested next to nine commonly used gene regions in sect. Alternaria, namely the SSU, LSU, ITS, gapdh, rpb2, tef1, Alt a 1, endoPG and OPA10-2 gene regions. The phylogenies from the two gene regions with a relatively low conservation, KOG1058 and KOG1077, could not distinguish the described morphospecies within sect. Alternaria more effectively than the phylogenies based on the commonly used gene regions for Alternaria. Based on genome and transcriptome comparisons and molecular phylogenies, Alternaria sect. Alternaria consists of only 11 phylogenetic species and one species complex. Thirty-five morphospecies, which cannot be distinguished based on the multi-gene phylogeny, are synonymised under A. alternata. By providing guidelines for the naming and identification of phylogenetic species in Alternaria sect. Alternaria, this manuscript provides a clear and stable species classification in this section.

    The study reported in this work takes place since 2009 at the Federal Institute of Education, Science and Technology of Santa Catarina, Campus Araranguá. Our main goal is to help form teachers, training undergraduate students in Natural Sciences with specialization in Physics as science communicators, as well as to promote actions of broader scientific popularization in the region of the town of Araranguá through an Astronomy Club called CA2. Among the actions of scientific popularization that the students promote are: video production, radio broadcasts, lectures, nightly observations, preparation and exhibition of posters, physics teaching for children, continuing education activities for teachers and regular physics teaching using Astronomy as a theme. The Club's teacher education and scientific dissemination work is based on the Theory of Meaningful Learning, always trying to reach the student's predisposition to learn and produce potentially meaningful material, the two essential conditions for meaningful learning to occur. O estudo que este trabalho relata ocorre desde 2009 no Instituto Federal de Educação, Ciência e Tecnologia de Santa Catarina, campus Araranguá. Nele procura-se formar divulgadores científicos durante a formação inicial de docentes do curso de Licenciatura em Ciências da Natureza com habilitação em Física, além de promover ações de divulgação científica para o público geral da região da cidade de Araranguá por meio de um Clube de Astronomia chamado CA² (Clube de Astronomia de Araranguá). Entre as ações de divulgação científica que os licenciandos promovem estão: produção de vídeos, programas de rádio, palestras, observações noturnas, confecção e exposição de pôsteres, ensino de física para crianças, formação continuada de professores em atividades e ensino de Física regular utilizando a Astronomia como tema gerador.

    Monsanto Company and Dow AgroSciences LLC have developed the combined-trait corn product MON 89034 × TC1507 × MON 88017 × DAS-59122-7 (SmartStax, a registered trademark of Monsanto Technology LLC). The combination of four biotechnology-derived events into a single corn product (stacking) through conventional breeding provides broad protection against lepidopteran and corn rootworm insect pests as well as tolerance to the glyphosate and glufosinate-ammonium herbicide families. The purpose of the work described here was to assess whether the nutrient, antinutrient, and secondary metabolite levels in grain and forage tissues of the combined-trait product are comparable to those in conventional corn. Compositional analyses were conducted on grain and forage from SmartStax, a near-isogenic conventional corn hybrid (XE6001), and 14 conventional reference hybrids, grown at multiple locations across the United States. No statistically significant differences between SmartStax and conventional corn were observed for the 8 components analyzed in forage and for 46 of the 52 components analyzed in grain. The six significant differences observed in grain components (p < 0.05) were assessed in context of the natural variability for that component. These results demonstrate that the stacked product, SmartStax, produced through conventional breeding of four single-event products containing eight proteins, is compositionally equivalent to conventional corn, as previously demonstrated for the single-event products.

    Minas artisanal cheese, produced in the Campo das Vertentes region of Brazil, is made from raw milk and endogenous starter cultures. Although this cheese is of great historical and socioeconomic importance, little information is available about its microbiological and physical-chemical qualities, or about its beneficial microbiota. This work was aimed at evaluating the qualities of the cheese and the components used for its production, comparing samples collected during the dry and rainy seasons. We also conducted molecular identification and isolated 50 samples of lactic acid bacteria from cheese (n=21), water (n=3), raw milk (n=9), and endogenous starter culture (n=17). The microbiological quality of the cheese, water, raw milk, and endogenous starter culture was lower during the rainy period, given the higher counts of coagulase-positive Staphylococcus and total and thermotolerant coliforms. Enterococcus faecalis was the lactic acid bacteria isolated most frequently (42.86%) in cheese samples, followed by Lactococcus lactis (28.57%) and Lactobacillus plantarum (14.29%). Lactobacillus brevis (5.88%), Enterococcus pseudoavium (5.88%), Enterococcus durans (5.88%), and Aerococcus viridans (5.88%) were isolated from endogenous starter cultures and are described for the first time in the literature. The lactic acid bacteria identified in the analyzed cheeses may inhibit undesirable microbiota and contribute to the safety and flavor of the cheese, but this needs to be evaluated in future research.

    The main theme of this article is that the socio-economic and educational changes which have occurred in industrialized countries in the past 20 to 25 years necessitate a thorough reform of the present system of teacher education. The first group of such changes includes the information explosion, greater occupational mobility, the growing significance and increasing role of the sciences, the development of the mass media, higher educational aspirations, technical development, the acceleration of the psycho-physical development of children and youth, and the injurious effects of the uncontrolled development of the constantly changing civilisation (deterioration of the human environment, diseases caused by the effects of civilisation, etc.). In the face of these changes, teachers must not remain indifferent and teacher education systems have to take them into account. Within the second group of changes influencing the content and methods of teacher education, the most important is the generalisation of education at the pre-school, primary and secondary school levels and also at the university level. As a result, education in many types of school and at ever higher levels has lost the elitist character it still had, not so long ago, and has become a mass activity. This has considerably affected teachers' work and, necessarily, also the work of the teacher education systems. In present-day schools it is necessary to emphasize not only the transmission of knowledge of the `know that' type, as was done in the past, but also problem-solving, independent individual and group work, etc., which will enable children and young people to acquire `know-how' and `know-why'. This must also be reflected in teacher education. In order to adapt the teacher education systems to the requirements of the changing society, a reform of the goals, contents and methods of the system will have to be prepared and implemented as a prerequisite and starting point for a global reform of the entire education system.

  17. Importance of land use update during the calibration period and simulation of water balance response to land use change in the upper Rio das Mortes Catchment (Cerrado Biome, Central-Western Brazil)

    Changes in the hydrological balance and following degradation of the water ecosystem services due to large scale land use changes are reported from agricultural frontiers all over the world. Traditionally, hydrological models including vegetation and land use as a part of the hydrological cycle use a fixed distribution of land use for the calibration period. We believe that a meaningful calibration - especially when investigating the effects of land use change on hydrology - demands the inclusion of land use change during the calibration period into the calibration procedure. The SWAT (Soil and Water Assessment Tool) model is a process-based, semi-distributed model calculating the different components of the water balance. The model bases on the definition of hydrological response units (HRUs) which are based on soil, vegetation and slope distribution. It specifically emphasises the role of land use and land management on the water balance. The Central-Western region of Brazil is one of the leading agricultural frontiers, which experienced rapid and radical deforestation and agricultural intensification in the last 40 years (from natural Cerrado savannah to cattle grazing to intensive corn and soya cropland). The land use history of the upper Rio das Mortes catchment (with 17500 km²) is reasonably well documented since the 1970th. At the same time there are almost continuous climate and runoff data available for the period between 1988 and 2011. Therefore, the work presented here shows the model calibration and validation of the SWAT model with the land use update function for three different periods (1988 to 1998, 1998 to 2007 and 2007 to 2011) in comparison with the same calibration periods using a steady state land use distribution. The use of the land use update function allows a clearer identification which changes in the discharge are due to climatic variability and which are due to changes in the vegetation cover. With land use update included into the

    Este trabalho apresenta o roteiro piloto de uma prática observacional em astronomia, junto com os primeiros resultados obtidos nesta fase de implementacão. O projeto, que será executado em duas etapas, visa introduzir noções de Astronomia a alunos do Ensino Médio e iniciantes nos cursos de Física. O experimento consiste em medir as órbitas dos satélites Galileanos e, a partir da análise dos dados coletados, verificar a validade da Lei das órbitas de Kepler, determinando a massa do planeta Júpiter. Em uma primeira etapa, as observações serão feitas utilizando um telescópio Meade LX200 10" e câmera CCD para obter uma seqüência de imagens do planeta, que possibilitará medir o movimento de seus satélites. A segunda etapa terá início a partir do funcionamento do telescópio em modo robótico, com a possibilidade de observações via internet por instituições de ensino. Para o desenvolvimento deste experimento foram inicialmente coletadas várias imagens de Júpiter obtidas com os instrumentos citados acima. Estas imagens serviram como base para confecção dos roteiros para a experiência no nível médio e superior. Os roteiros serão inicialmente apresentados em uma home-page. Nela também se buscará uma contextualização histórica da experiência bem como o estabelecimento de relações com professores e alunos, propostas metodológicas e a disponibilização dos programas computacionais necessários para a utilização "on-line" pelos usuários. O projeto conta com apoio da Fundação VITAE.

    Introducción: el concepto de “control calorico estricto” surgio para evitar la excesiva y la deficiente nutricion de los pacientes. Objetivo: describir y validar una ecuacion simplificada para el calculo del gasto energetico total (GET) en pacientes criticos con ventilacion mecanica. Métodos: analisis secundario de las mediciones de GET por calorimetria indirecta en pacientes criticos. Los pacientes fueron asignados de forma 2:1 por un paquete estadistico; el primer grupo se empleo para desarrollar la nueva ecuacion predictiva del GET (grupo predictivo) y el segundo para validarla (grupo validacion). La calorimetria indirecta se realizo con tres calorimetros diferentes: la bolsa de Douglas, un computador metabolico y el equipo CalorimetR. Hemos desarrollado la nueva ecuacion predictiva del GET utilizando el GET medido (en kcal/kg/d), como variable dependiente, y como variables independientes los diferentes factores que influyen en el gasto energetico: edad, genero, indice de masa corporal (IMC) y tipo de lesion. Resultados: el grupo de prediccion incluyo 179 pacientes y el de validacion 91 pacientes. La ecuacion predictiva fue: GETEP = 33 - (3 x E) - (3 x IMC) - (1 x G). Donde: E (edad en anos): ≤ 50 = 0; > 50 = 1. IMC (kg / m2): 18,5- 24,9 = 0; 25-29,9 = 1; 30-34,9 = 2; 35-39,9 = 3. G (genero): hombre = 0; mujer = 1. El sesgo (IC del 95%) entre el GET medido y el predicho fue de -0,1 (-1,0 a 0,7) kcal/ kg/dia y los limites de acuerdo (} 2SD) fueron -8,0 a 7,8 kcal/kg/d. El GET por la ecuacion predictiva fue preciso (entre el 85% y el 115%) en el 73,6% de los pacientes. Conclusiones: La nueva ecuacion predictiva fue aceptable para predecir el GET de la mayoria de pacientes criticos con ventilacion mecanica en la practica clinica.

  9. Parasitism in optima forma: exploiting the host fibrinolytic system for invasion.

    PubMed

    Figuera, Lourdes; Gómez-Arreaza, Amaranta; Avilán, Luisana

    2013-10-01

    The interaction of pathogenic bacteria with the host fibrinolytic system through the plasminogen molecule has been well documented. It has been shown, using animal models, to be important in invasion into the host and establishment of the infection. From a number of recent observations with parasitic protists and helminths, emerges evidence that also in these organisms the interaction with plasminogen may be important for infection and virulence. A group of molecules that act as plasminogen receptors have been identified in parasites. This group comprises the glycolytic enzymes enolase, glyceraldehyde-3-phosphate dehydrogenase and fructose-1,6-biphosphate aldolase, in common with the plasminogen receptors known in prokaryotic pathogens. The interaction with the fibrinolytic system may arm the parasites with the host protease plasmin, thus helping them to migrate and cross barriers, infect cells and avoid clot formation. In this context, plasminogen receptors on the parasite surface or as secreted molecules, may be considered virulence factors. A possible evolutionary scenario for the recruitment of glycolytic enzymes as plasminogen receptors by widely different pathogens is discussed.

  10. Molecular Characterization of FT and FD Homologs from Eriobotrya deflexa Nakai forma koshunensis

    PubMed Central

    Zhang, Ling; Yu, Hao; Lin, Shunquan; Gao, Yongshun

    2016-01-01

    In angiosperms, regulation of flowering is a vital process for successful reproduction. To date, the molecular mechanism of flowering is well-studied in the model plant, Arabidopsis, in which key genes such as FLOWERING LOCUST (FT) or FD have been identified to regulate flowering. However, the flowering mechanisms are still largely unknown in fruit trees like loquat. To this end, we first cloned one FT- and two FD-like genes from the loquat (Eriobotrya deflexa Nakai f. koshunensis) and referred to as EdFT, EdFD1, and EdFD2, respectively. Phylogenetic analysis has shown that EdFT, EdFD1, and EdFD2 are conserved during the evolution process. EdFT is mainly expressed in reproductive tissues (e.g., flower buds, flowers, and fruits), while EdFD1 and EdFD2 are mainly expressed in apical buds including leaf buds and flower buds. EdFT is localized in the whole cell, while EdFD1 or EdFD2 is localized in the nucleus. Ectopic expression of EdFT, EdFD1, and EdFD2 in Arabidopsis results in early flowering. In addition, we have also revealed that the EdFT interacts with both EdFD1 and EdFD2. Overall, these data suggest that the EdFT, EdFD1, and EdFD2 are the functional homologs of FT and FD, respectively, which might act together to regulate loquat flowering through a similar mechanism found in Arabidopsis.

    SUCCESS FACTORS OF APPRENTICESHIP MARKETING IN A SYSTEM OF DUAL VOCATIONAL TRAINING: THE CASE OF SWITZERLAND - The dual system of vocational training, utilizing both company training and vocational school, is generally acknowledged to be a successful model, but a decreasing number of trainee posts in Switzerland poses a crisis for the approach. One strategy for overcoming the problem involves offering incentives for companies to create new trainee posts. The present study explores the necessary conditions for successfully influencing the number of trainee posts through apprenticeship marketing. A comparision of qualitative case studies of six marketing projects demonstrates that while context, in the sense of basic structural conditions and political sensibility for the problematic, plays a role in the success of a project, what is central is above all the form of the trainee-post marketing project itself. This has to do with the behaviour of the actors involved as well as the choice of the mode of governance and project organization. The latter has to do with making available requisite technical and personal resources, coordination on the part of the project direction, and giving those responsible the necessary room to act in implementing the project.

    We study the numerical propagation of waves through future null infinity in a conformally compactified spacetime. We introduce an artificial cosmological constant, which allows us some control over the causal structure near null infinity. We exploit this freedom to ensure that all light cones are tilted outward in a region near null infinity, which allows us to impose excision-style boundary conditions in our finite difference code. In this preliminary study we consider electromagnetic waves propagating in a static, conformally compactified spacetime.

    At a regional scale, a variety of actors from all three sectors of private, public and civil society act together in a philanthropic field. This article deals with the question of how cooperation in charitable action unfolds in this field. Using the example of the region of Heilbronn-Franconia, the empirical case unpacks the dominance of local and regional forms of philanthropy and reconstructs two successful examples of intersectoral collaboration. However, the analysis also demonstrates the limits of the external designability that are due to the individuality of charitable actors, their diverse objectives and the contextuality of the regional environment. The realization of synergies through regional governance therefore succeeds only by respecting the dedication and self-determination of philanthropic commitment and by creating legitimate and sensitive structures of moderation and facilitation.

    Introduccion. La anemia falciforme es la forma homocigota, grave, de drepanocitosis, un trastorno genetico, frecuente en raza negra, caracterizado por la produccion de hemoglobina S, anemia hemolitica cronica e isquemia tisular por alteracion del flujo sanguineo. Una cuarta parte de los pacientes presenta manifestaciones neurologicas; el 8-10% de los niños sufrira un ictus. Objetivo. Analizar los casos de ictus en niños con anemia falciforme en nuestro centro. Pacientes y metodos. Estudio descriptivo retrospectivo de niños con anemia falciforme e ictus. Resultados. Se recogieron cinco pacientes (dos dominicanos y tres guineanos) con anemia falciforme e ictus; un paciente sufrio dos episodios ictales. La edad media fue de 27 meses. Cinco episodios fueron infartos isquemicos. El ictus fue la forma de inicio de la drepanocitosis en tres ocasiones. Dos de los ictus ocurrieron en un contexto de meningitis neumococica. En cuatro pacientes hubo fiebre previa. La clinica inicial fue hemiparesia en cuatro casos. La hemoglobina media al diagnostico de ictus fue de 6,5 g/dL. En tres pacientes se hallaron alteraciones en la ecografia transcraneal y, en todos los pacientes, lesiones en la resonancia magnetica, que en la mitad eran bilaterales. Tras el ictus se inicio un protocolo de regimen hipertransfusional, y solo un paciente presento un nuevo ictus, que desarrollo un sindrome moya-moya y fue sometido a una revascularizacion indirecta, con buena evolucion, sin presentar nuevos eventos isquemicos posteriores. Conclusiones. La drepanocitosis es una enfermedad emergente en nuestro medio debido a la inmigracion. Debe sospecharse en ictus pediatricos asociados a anemia, sobre todo en menores de 5 años de raza negra no sometidos a cribado neonatal.

    formación. Aparte de eso, los datos levantados en este trabajo apuntan para un número bajo de afiliados a la SAB (Sociedade Astronômica Brasileira) en los cursos investigados. Se verificó que tener astrónomos en una institución no implica tener una disciplina obligatoria de Astronomía en el curso de licenciatura en Física. Este artigo é o resultado de uma pesquisa sobre a formação básica em Astronomia nos cursos de Licenciatura em Física que fizeram o exame nacional ENADE 2011. O objetivo do trabalho foi identificar se há disciplinas de Astronomia nesses cursos, se ela é obrigatória ou optativa/eletiva, qual a sua carga horária e o período em que é oferecida. Pesquisou-se também a relação entre astrônomos, cursos de Licenciatura em Física e disciplinas de Astronomia. Para realizar essa pesquisa utilizamos os dados do ENADE 2011 e também do censo da Astronomia brasileira. Como resultado, se observa que em apenas 15% dos cursos existe uma disciplina obrigatória de Astronomia e que há uma grande probabilidade de que 85% dos professores de Física formados em 2011 não cursaram nenhuma disciplina de Astronomia durante a graduação. Além disso, os dados levantados nesse trabalho apontam um baixo número de filiados à SAB nos cursos pesquisados. Identifica-se que ter astrônomos na instituição não implica em disciplina obrigatória de Astronomia no curso de Licenciatura em Física.

    The heart of the bird is characterized by its enormous efficiency. Racing pigeons are bred for a long time for their flight performance. In the present study therefore the heart of 108 racing pigeons of the breed Bricoux were examined by means of echocardiography. The birds were either kept in aviaries (untrained) or as racing birds. The aim was to find out whether differences in the heart dimensions and/or the heart work occur between untrained and trained birds, like it is described already in humans and mammals (so-called athletic's heart). Significant differences between the two groups could be determined with different parameters, in particular with parameters, which affect the heart work. Thus it was for the first time possible to prove the formation of a athletic's heart in birds, and by that the adaptation of the avian heart to appropriate performance requirements. PMID:12058599

    The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4,383 young adults aged 17 to 22 years (1,918 Spanish, 44%, and 2,465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish factor weights, nor the variances and covariances of the factors, or the error variances of items. Finally, the internal consistency of the five scales was good in the samples of both countries.

    The aim is to analyse the negative influence of high panel temperatures on electrical production when they are placed on steel roofs of industrial buildings and greenhouse roofs. Different configurations have been tested in order to allow cooling of photovoltaic panels to decrease panel temperature and improve electrical performance. To research this problem two experimental facilities have been built. The first facility includes two panels fixed on a structure. A panel is integrated on a parallel steel plate which does not allow sufficient cooling. Between both surfaces, there is an open air channel in which an air flow is created by the chimney effect thus cooling the panel by natural convection or inducing air, using a fan, by forced convection. The other panel has not any plate underneath it and is used as a referent. The electrical behaviour of the integrated panel has been studied for different air gaps and induced velocities, being also compared with the reference panel. An experimental model was developed to establish correlations which allow determine the panel temperature depending on the influential variables on the cooling ability. This research also analyses the data of a working solar plant, with the same panel model, obtaining the correlations between electrical variables and panel temperature. A comparison with the electrical behaviour in the experimental facility and the solar plant is also presented. The second experimental facility is a replica of a photovoltaic greenhouse. It consists of four photovoltaic panels placed on the plastic roof, providing an open and divergent channel between both surfaces thus creating an air flow by natural convection. This research studies the effect of high temperatures within the greenhouse which is transferred by the roof and thus affects the electrical production. In addition, two air gaps were used and the effect of adding insulating material to the plastic roof was studied. The electrical variables of the panels are analysed to compare and select the best configuration. The presented research provides a deep knowledge of how they work as well as information and results for an improvement in future designs of building integrated photovoltaic systems. Este estudio se centra en analizar la influencia negativa de la temperatura en la produccion electrica de paneles fotovoltaicos al estar emplazados sobre cubierta de acero, como sucede en naves industriales y sobre un invernadero. Se estudian diferentes configuraciones que permitan refrigerar los paneles, reduciendo su temperatura y mejorar su rendimiento. Para abordar este problema, se han construido dos instalaciones experimentales, fieles a plantas solares en funcionamiento. Una instalacion engloba dos paneles fotovoltaicos sobre estructura fija al suelo. Uno de los paneles esta integrado sobre una superficie paralela y metalica. Entre ambas superficies existe un espacio que posibilita circular aire, permitiendo refrigerar el panel por conveccion natural, o conveccion forzada impulsando el aire con un ventilador. El otro panel, libre por su cara posterior y se ha considerado de referencia. Se ha estudiado el comportamiento del panel integrado sobre cubierta para diferentes secciones de aire y velocidades inducidas, comparandolo con el panel de referencia. Se ha desarrollado un modelo experimental que nos permite determinar la temperatura del panel en funcion de las variables que influyen en su refrigeracion. Adicionalmente, se han analizado los datos de una planta solar en funcionamiento, con paneles de igual caracteristicas, obteniendo correlaciones entre la temperatura del panel y las variables electricas y comparandolos con las obtenidas en la instalacion experimental. La segunda instalacion experimental reproduce parte de una instalacion solar sobre un invernadero, formada por cuatro paneles fotovoltaicos colocados sobre el plastico del invernadero, existiendo un canal divergente entre ambas superficies. Se estudia la influencia de las altas temperaturas en el interior del invernadero sobre la produccion electrica de los paneles, decido a la transferencia de calor del interior del invernadero. Ademas, se han ensayado dos separaciones diferentes y para cada una se ha comparado con la misma, utilizando un aislante sobre la cubierta. El estudio realizado sobre ambas instalaciones ha proporcionado un conocimiento profundo del funcionamiento de cada una de ellas, asi como informacion valida para una mejora de futuros disenos de instalaciones fotovoltaicas sobre cubiertas.

    ERTS-1 digital data in the form of computer compatible tapes provide the geoscientist with an unusual opportunity to test the maximum flexibility of the satellite system using interactive computers, such as the General Electric Image 100 System. Approximately 9 hours of computer and operator time were used to analyze the Lake Titicaca image, 1443-14073, acquired 9 October 1973. The total area of the lake and associate wetlands was calculated and found to be within 3 percent of previous measurements. The area was subdivided by reflectance characteristics employing cluster analysis of all 4 bands and later compared with density values of band 4. Reflectance variations may be attributed to surface roughness, water depth and bottom characteristics, turbidity, and floating matter. Wetland marsh vegetation, vegetation related to ground-water effluents, natural grasses, and farm crops were separated by cluster analysis. Sandstone, limestone, sand dunes, and several volcanic rock types were similarly separated and displayed by assigned colors and extended through the entire scene. Waste dumps of the Matilde Zinc Mine and smaller mine workings were tentatively identified by signature analysis. Histograms of reflectance values and map printouts were automatically obtained as a record of each of the principal themes. These themes were also stored on a work tape for later display and photographic record as well as to serve in training. The Image 100 System is rapid, extremely flexible and very useful to the investigator in identifying subtle features that may not be noticed by conventional image analysis. The entire scene, which covers 34,225 km2, was analyzed at a scale of 1:600,000, and portions at 1:98,000 and 1:25,000, during a 9-hour period at a rental cost of $250 per hour. Costs to the user can be reduced by restricting its uses to specific areas, objectives, and procedures, rather than undertaking a complete analysis of a total scene.

    This paper presents a historical retrospective concerning data from a research in Astronomy Education in Brazil, after 1973. It was organized on the basis of the speech analysis of national researchers considered references in this field by their peers. Furthermore, it was elaborated on the basis of other studies from the areas of Science Education, Physics and Astronomy. This historical overview was developed in order to facilitate understanding of the contexts in which the interviewed researchers have developed professionally. Moreover, we attempted to recover the memory of the growing field of research in Astronomy Education in the country. We believe that the history presented can help those trying to understand the past in an attempt to resolve current and future demands.

    Johnson, R. A.

    1972-01-01

    The efforts of researchers at Mississippi State University to utilize space-age technology in the development of a self-contained, portable data acquisition system for use in marine and ecological research are presented. The compact, lightweight data acquisition system is capable of recording 14 variables in its present configuration and is suitable for use in either a boat, pickup truck, or light aircraft. This system will provide the acquisition of reliable data on the structure of the environment and the effect of man-made and natural activities on the observed phenomenon. Utilizing both self-contained analog recording and a telemetry transmitter for real-time digital readout and recording, the prototype system has undergone extensive testing.

    The hot impact densification (HID) is a new powerful method for producing ceramic fuel pellets for nuclear reactors. Green ceramic bodies are directly processed to pellets by high speed shaping in the plastic temperature region of ceramic material. Opposed to the well established press sintering procedure it can be heated, densified, and cooled by orders of magnitude faster. Therefore, at high throughputs, small equipment dimensions become possible. The fuel pellets produced meet all requirements, particular the dimensional tolerances achieved are very closed, consequently circular grinding is omitted. Furthermore, the relatively high temperature level of the impact pressing favors the mixed crystal formation of uranium and plutonium oxide. This improves the solubility of the fuel in nitric acid, an essential point at reprocessing. A prototype facility is designed so that automatic fabrication in continuous operation will be possible. The target working cycle for a fuel pellet is in the range of some seconds.

    2001-03-01

    Promotion of creativity in the cause of peace and international understanding is a fundamental part of the UNESCO programme to build a culture of peace. A central aspect of this undertaking consists in encouraging children to express themselves freely on this subject in writing and art. An approach has been developed to stimulate children's creativity and to create a link between creative expression and education for intercultural understanding. This article is divided into two parts. The first explains the pedagogical and psychological concepts behind this approach. The second describes a project in which these concepts were applied. It focuses on a minority dispersed over many parts of the world, namely children of Tibetan families. The description is accompanied by commentaries of the Fourteenth Dalai Lama, arising from a personal audience granted to the author in 1999.

  1. Auswirkungen einer Pipeline-Verlegung auf das marine Benthos im Tidebecken von Baltrum-Langeoog

    NASA Astrophysics Data System (ADS)

    van Bernem, K. H.

    1999-12-01

    In order to investigate possible effects on benthic communities resulting from the landfall of the “EU-ROPIPE” gas pipeline in areas of the Wadden Sea National Park of Lower Saxony the following seasonal surveys were carried out by the GKSS-Research-Centre during 1993 1997: a) Assessment of species number and abundance of subtidal and intertidal macrofauna, b) Intertidal documentation of demersal fish and decapod crab stocks, c) Intertidal assessment of species composition and abundance of microalgae. Sublittoral sampling was mainly carried out by bottom-grabs and box-dredges at about 120 locations recorded by GPS. Sediment cores of intertidal benthic communities at 6 locations were processed for macrofauna and microalgae. Species numbers and abundances of sublittoral benthic macrofauna decreased during 1994 as well in those areas directly affected as well as in areas 500 to 1000m removed from the construction activities. Most notably, the relatively high species richness of a hard-bottom community, rare in Wadden Sea areas, was strongly disturbed. During the same period the spatial distribution and abundance of intertidal filter feeders decreased as well as the abundance of vagile predating polychaetes and amphipods at locations situated near low tide level. A local stock of the low dispersive Goby ( Pomatoschistus microps) was nearly totally destroyed. Decreases in the abundances of juvenile Plaice ( Pleuronectes platessa) and decapod crabs ( Crangon crangon, Carcinus maenas) could only be shown during July/October 1994 in those areas of working activities which were directly connected to the tidal migration paths of these species. During 1994/95 numbers and abundances of diatom species prefering fine grained sediments with a high amount of organic material increased significantly. A recovery started immediately after conclusion of the refilling measures in 1995. A complete documentation of the community-resilience, however, was masked by fluctuations following the ice-winter in 1995/96.

  2. Kepler, Galilei, the telescope and the consequences. (German Title: Kepler, Galilei, das Fernrohr und die Folgen)

    NASA Astrophysics Data System (ADS)

    Gaulke, Karsten; Hamel, Jürgen

    The papers of this volume are dedicated to Johannes Kepler, the astronomy of his time, and the consequences of his researches. They deal with the reception on the Copernican system of the world at the court of landgrave William IV in Kassel and the use of astronomy at a princely court in the 16th century, exemplified by the Kassel residence. Two contributions discuss a text fragment in Kepler's Astronomia Nova and the dimensions of the geo- and heliocentric systems of the world in Kepler's Mysterium Cosmographicum. Other contributions deal with mathematical aspects un Kepler's exchange of letters, the biography of Kepler's discussion partner Ph. Feselius, as well as the early reception of the Tabulae Rudolphinae in the calendar literature, telescopes in Kepler's time, Chr. Scheiner's optical theory of the eye, and finally in the continuation of the heliocentric world system by Otto von Guericke's natural philosophy and science. In conclusion, the documents of the planned call of Kepler to Rostock university, as well as the first publication of a recently found, hitherto unknown letter by Kepler.

  3. Das Werden des Kosmos. Von der Erfahrung der zeitlichen Dimension astronomischer Objekte im 18. Jahrhundert.

    NASA Astrophysics Data System (ADS)

    Krafft, F.

    This paper deals with two of the initial stages through which the dimension of time, in the sense of an irreversible development, found its way into astronomical-cosmological thinking. The one resulted from the first consequential application of Newtonian principles and laws to cosmic entities outside of our solar system found in the "General Natural History or Theory of the Heavens" by Immanuel Kant. The other initial stage is found in the classification of 'nebulae' by William Herschel who introduced the historical time factor as a principle of order in addition to the outward shape, which had become common for all the different elements in natural history during the second half of the 18th century.

  6. Der Haupthistokompatibilitätskomplex und die Unterscheidung zwischen Selbst und Fremd durch das Immunsystem

    NASA Astrophysics Data System (ADS)

    Klein, Jan; Rammensee, Hans-Georg; Nagy, Zoltan A.

    1983-06-01

    The major histocompatibility complex (Mhc) is a cluster of closely linked genes which are involved in the distinction between self and non-self. The genes fall into two classes, I and II, which are evolutionarily related but specialized to performing somewhat different functions. The Mhc genes code for proteins which are seen together with foreign substances by the thymus-derived lymphocytes. These lymphocytes thus recognize simultaneously self (Mhc molecules) and non-self (foreign antigen). Some of the Mhc genes are highly polymorphic and this polymorphism probably represents a compensation for the fact that certain combinations of Mhc molecules and antigen fail to be recognized by the T lymphocyte.

    Lambrecht, Astrid

    2005-03-01

    Die Casimir-Kraft zwischen zwei Spiegeln im Vakuum wird durch Vakuumfluktuationen verursacht. Dieser bedeutende Effekt ermöglicht es, in präzisen Laborversuchen unser Verständnis vom Quantenvakuum zu vertiefen. Eine Vielzahl neuer Experimente setzt dazu moderne Techniken wie die atomare Kraftmikroskopie oder mikroelektromechanische Systeme ein. Auch die theoretischen Modelle werden verbessert, um diese Experimente realistischer nachzubilden. Bislang stimmen die experimentellen Daten gut mit den theoretischen Vorhersagen überein. Da der Casimir-Effekt auf kurzen Distanzen dominieren kann, wird er für die zukünftige Nanotechnik wichtig sein. Der Grundlagenforschung bietet er eine gute Möglichkeit, neue Theorien zur Vereinigung aller Kräfte zu überprüfen.

  9. Diskrepanzen und Kongruenzen: Das Dilemma des afrikanischen Kindes zwischen Familie und Schule

    NASA Astrophysics Data System (ADS)

    Bauer, Annemarie

    1986-03-01

    This article expounds the theory that the failure of school is due to the incompatibility of the educational goals of school and traditional upbringing in Africa. The thesis is put forward by adherents of the psychoanalytical model of child development and seeks to emphasize the discrepancies between the childhood where children are not frustrated and where their needs are cared for and the school education which represses the drives and its socialization of children. Finding a number of anthropological studies are discussed and reinterpretations of the ethno-psychoanalytical materials attempted. Neither the evaluation of childhood in Africa nor the theory that with school come wholly new expectations of behaviour (e.g., a performance requirement) can no longer be maintained. In conclusion, other explanations for the difficulties encountered by school in Africa are offered.

    , al solsticio de junio, al equinoccio de septiembre y al solsticio de diciembre. Además, se dictaron clases teóricas en la sala de aula. Estos métodos buscaron construir conceptos en torno al movimiento aparente del Sol y la sucesión de las estaciones. Teniendo en cuenta los resultados de las actividades se aplicó una evaluación cuyos datos demuestran la existencia de un aprendizaje deseado por los estudiantes en cuanto a: el reconocimiento de los puntos cardinales, la descripción del movimiento solar aparente y la aparición de las estaciones y su alternancia a partir de observaciones astronómicas visuales sin instrumentos. Muitas concepções alternativas são reconhecidas entre os diversos grupos de estudantes, em especial nos da educação básica. Dentre elas, o movimento aparente do Sol, por mais quotidiano que seja, proporciona variadas interpretações. Deste modo, observar e registrar o movimento dos astros na abóboda celeste é uma tarefa necessária ao ensino de Astronomia. O trabalho que ora se apresenta propõe a apresentação dos resultados da observação do movimento aparente do Sol por intermédio da marcação da sombra de um gnômon vertical por alunos de uma turma do sexto ano do ensino fundamental de uma escola do campo do Paraná. O projeto em si ocorreu em quatro etapas, em datas próximas do equinócio de março, do solstício de junho, do equinócio de setembro e do solstício de dezembro. Além disso, foram desenvolvidas aulas teóricas em sala de aula. Tais métodos buscaram construir conceitos em torno da movimentação aparente do Sol e da alternância das estações do ano. Diante dos resultados provenientes das atividades desenvolvidas foi aplicada uma avaliação e os dados demonstraram um aprendizado desejado dos alunos quanto: ao reconhecimento dos pontos cardeais; à descrição do movimento solar aparente e a ocorrência das estações do ano e sua alternância a partir de observações astronômicas a olho nu.

Our scope is essentially that of active events that occur in the solar atmosphere covering wide temporal and spatial scales and energy range. We present results derived from the comparative analysis of active events and their interplanetary counterparts, as well as of aspects related to the quiet solar atmosphere, such as the heating of the corona and the origin of the slow solar wind.

  16. Induced resistance in melon plants against Fusarium oxysporum f.sp. melonis caused by a nonpathogenic isolate of the same formae specialis.

    PubMed

    Chikh-Rouhou, H; Alvarez, M; González-Torres, R

    2006-01-01

    Melon 'Charentais T' susceptible to Fusarium oxysporum f. sp. melonis (Fom) race 1.2 was pre-inoculated, as a resistance inducer agent, with a nonpathogenic isolate of Fom. The biocontrol agent was only effective when it was applied one or two days before a challenge inoculation with the pathogen. Simultaneous inoculation did not provide any durable protection. Melon cv 'Charentais Fom 1' carries a single dominant gene conferring resistance against Fom races 0 and 2, whereas 'Charentais Fom 2' carries a single dominant gene conferring resistance against races 0 and 1 but both genotypes are susceptible to Fom race 1.2. Co-inoculation with conidia of race 0 provided almost complete protection against the pathogenic race 1.2. It may be hypothesised that while in contact with the host, the non-pathogenic races of the melon Fusarium either possess or secrete an inducing factor causing a defence reaction in melons possessing a resistance gene and preventing the proliferation of the pathogenic race either by formation of a mechanical barrier or by the synthesis of fungistatic substances.

    Antecedentes: los anticuerpos antinucleares son inmunoglobulinas que reconocen componentes celulares nucleares y citoplasmáticos autólogos. En personas sanas no se relacionan con alguna enfermedad autoinmune; sin embargo, pueden estar vinculados con un fenotipo inmunológico de riesgo que no ha sido suficientemente estudiado. Objetivo: examinar la existencia de anticuerpos antinucleares en el suero de donadores de sangre. Material y métodos: estudio transversal y analítico en búsqueda de anticuerpos antinucleares en suero mediante inmunofluorescencia indirecta en células HEp-2. La prevalencia y patrón de expresión se contrastaron con la edad, el género y los antecedentes de enfermedad reumática o tiroidea. Resultados: se estudiaron 379 donadores de sangre con límites de edad entre 18 y 65 años. La prevalencia de anticuerpos antinucleares en la población estudiada fue de 13%. La mayoría de los sujetos positivos tenía entre 21 y 40 años de edad. El género masculino expresó mayor proporción de positividad (11%) en comparación con las mujeres (2%). De la misma forma, 82% de los hombres tenía títulos bajos (1:80) y en 66% eran de tipo nucleolar (RM = 10.66 [1.83 a 62.18]; p = 0.007). Conclusiones: en individuos sanos, la existencia de anticuerpos antinucleares a títulos bajos puede no significar un estado de autoinmunidad; sin embargo, podría ser el reflejo de una exposición a factores ambientales que no han sido lo suficientemente estudiados. Es necesario realizar nuevos estudios en población sana que permitan explicar la asociación entre estos anticuerpos y los factores tóxicoambientales, así como sus efectos en la salud.

    Introducción: Los comedores escolares cuentan con normativa de gestión y supervisión de menús, sin embargo no se ha valorado si son consumidos en su totalidad. Objetivo: Valorar la aceptación de alimentos mediante pesado de restos y validación de una metodología visual para su estimación en comedores escolares de Murcia. Metodología: Participaron escolares de segundo y tercer ciclo de educación primaria, de 8-12 años. La estimación de restos se realizó mediante pesado de alimentos de 765 bandejas. La valoración visual (300 bandejas) se realizó con escala categórica: 1 = 0-25%; 2 = 26-50%; 3 = 51- 75% y 4 = 76-100%, por dos dietistas y se valoró la fiabilidad con respecto al pesado de alimentos. La concordancia entre ambos métodos fue evaluada en dos muestras estratificadas por la presencia/ausencia de cocina en la escuela. Resultados: Los primeros platos con más restos fueron pasta, arroz y purés de verduras siendo mayor en aquellos colegios sin cocina en el centro (p < 0,05). También los segundos platos a base de legumbres, ave y pescado y ensaladas de guarnición. Las frutas y el total de restos son superiores en colegios sin cocina (p < 0,05). La concordancia entre evaluadoras fue alta en platos a base de carnes y en ensaladas, y considerable en legumbres, precocinados, tortilla de huevo, pasta, pescado y arroz. Conclusiones: Los restos son elevados y existieron diferencias en la aceptación de ciertos alimentos acorde al tipo de menú ofertado. La escala visual es una herramienta confiable para medir la aceptación de forma indirecta, pero necesita capacitación y entrenamiento del personal implicado.

  20. População estelar jovem em galáxias irregulares próximas

    NASA Astrophysics Data System (ADS)

    Guimarães, T. A.; Telles, E.

    2003-08-01

    A análise do conteúdo estelar de galáxias próximas através da fotometria das suas estrelas resolvidas nos fornece informações importantes sobre a história de formação estelar e os processos de formação estelar em galáxias, que estão diretamente ligados ao estudo de evolução de galáxias. Quando nenhuma estrela puder ser resolvida o método mais poderoso consiste na análise do conteúdo estelar integrado das galáxias através das suas cores integradas em conjunto com informação espectroscópica que combinados com modelos de síntese evolutiva podem restringir simultaneamente a função de massa inicial (IMF) e a taxa de formação estelar (SFR). Nesse contexto, galáxias do tipo tardio, em particular, irregulares, são relevantes por várias razões: elas são objetos relativamente simples, com alta atividade de formação estelar e são objetos relativamente jovens (geralmente apresentam baixas abundâncias de elementos pesados e grande quantidade de gás). Apresentamos uma análise fotométrica de uma amostra de 7 galáxias do tipo tardio do universo local (NGC 2366, NGC 4395, NGC 4656, NGC 4214, NGC 4236, HOII, IC2574) que foram observadas com uma boa resolução espacial nas bandas B, V e R no telescópio Isaac Newton de 2.5m de Roque de los Muchachos nas Ilhas Canárias, Espanha. A distribuição espacial da população estelar jovem dessas galáxias é discutida sobre os pontos de vista dos íindices de cor integrados e dos seus diagramas cor magnitude, que comparados com isócronas teóricas, nos fornecem informações sobre os eventos de formação estelar, como por exemplo, indicações sobre a idade dos mesmos. As principais conclusões do trabalho podem ser resumidas em: (i) As galáxias irregulares possuem formação estelar recente (FE) espalhada ocorrendo nos últimos 50 Manos; (ii) A formação estelar em galáxias irregulares não é auto-propagante em escalas globais ( > 100 pc) ; (iii) A FE pode ser auto-regulável em escalas

    2008-09-01

    Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

    By two exemplary clinical situations — acute viral hepatitis, acute-phase reaction of the liver — the significance of basic research for the understanding of clinical phenomena and for the development of new diagnostic and therapeutic procedures is demonstrated. The very different phenomena following infection with the hepatitis-B-virus can be explained by the variation in the interactions of virus and liver cell, by the immune reaction of the host, and by mutants of the virus. The reaction of the liver to an extrahepatic infection is mediated by interleukin-6, and characterized by an alteration in protein metabolism. The synthesis of acute-phase proteins is increased. The proteins confine the local injury and establish the homeostasis of the organism.

    BACKGROUND Dermatomyositis affects striated muscles, skin and other organs. OBJECTIVE To characterize the disease from January 1992 to December 2002, assessing its classification, cutaneous and systemic manifestations, and also laboratory results, therapeutic and prognostic findings compared to those in the literature. METHODS Data were obtained from medical records of 109 patients who were classified into five groups: 23 juvenile dermatomyositis; 59 primary idiopathic dermatomyositis; 6 amyopathic dermatomyositis; 7 dermatomyositis associated with neoplasms and 14 dermatomyositis associated with other connective tissue diseases. RESULTS Sixty patients were classified as "definite" diagnosis; 33 as "possible"; four as "probable" and 12 and as amyopathic. The average age at diagnosis was 36 years. Cutaneous manifestations occurred in all patients; the most frequent symptom was loss of proximal muscle strength; the most common pulmonary disorder was interstitial lung disease, and gastritis was the most prevalent digestive manifestation. Tumors were documented in 6.42% of cases. Lactate dehydrogenase was the muscle enzyme most frequently elevated in the majority of cases. Skin biopsies were performed in 68 patients; muscle biopsies in 53; and electroneuromyographies in 58 patients. The most commonly used treatment was corticotherapy and the mortality rate was 14.7%. CONCLUSION in this sample, the disease appeared in younger individuals, was more frequent in women and the association with cancer was small. PMID:25184910

    Events do have, in addition to economic effects, impact on the quality of life of the affected population. Using a case study from the city of Bamberg this article addresses the subjective contentment with larger events. The results show variation in the range of contentment depending on age and time of residency in the city. Furthermore, it becomes obvious that the particular expectation on "life in the inner city" shapes the contentment. Cities should pay attention to this social heterogeneity when deploying strategies of revitalisation through festivals and events. They should take it seriously by using tools of collaborative planning to preserve the multi-functionality of inner cities.

  9. Continuous Hidden Markov Models: Application to automatic earthquake detection and classification at Las Canãdas caldera, Tenerife

    2008-10-01

    A possible interaction of (volcano-) tectonic earthquakes with the continuous seismic noise recorded in the volcanic island of Tenerife was recently suggested. Also recently the zone close to Las Canadas caldera shows unusual high number of near (< 25 km), possibly volcano-tectonic, earthquakes indicating signs of reawakening of the volcano putting high pressure on the risk analyst. Certainly for both tasks consistent earthquake catalogues provide valuable information and thus there is a strong demand for automatic detection and classification methodologies generating such catalogues. Therefore we adopt methodologies of speech recognition where statistical models, called Hidden Markov Models (HMMs), are widely used for spotting words in continuous audio data. In this study HMMs are used to detect and classify volcano-tectonic and/or tectonic earthquakes in continuous seismic data. Further the HMM detection and classification is evaluated and discussed for a one month period of continuous seismic data at a single seismic station. Being a stochastic process, HMMs provide the possibility to add a confidence measure to each classification made, basically evaluating how "sure" the algorithm is when classifying a certain earthquake. Moreover, this provides helpful information for the seismological analyst when cataloguing earthquakes. Combined with the confidence measure the HMM detection and classification can provide precise enough earthquake statistics, both for further evidence on the interaction between seismic noise and (volcano-) tectonic earthquakes as well as for incorporation in an automatic early warning system.

    The ever-increasing amount of data handled by the CMS dataflow and workflow management tools poses new challenges for cross-validation among different systems within CMS experiment at LHC. To approach this problem we developed an integration test suite based on the LifeCycle agent, a tool originally conceived for stress-testing new releases of PhEDEx, the CMS data-placement tool. The LifeCycle agent provides a framework for customising the test workflow in arbitrary ways, and can scale to levels of activity well beyond those seen in normal running. This means we can run realistic performance tests at scales not likely to be seen by the experiment for some years, or with custom topologies to examine particular situations that may cause concern some time in the future. The LifeCycle agent has recently been enhanced to become a general purpose integration and validation testing tool for major CMS services. It allows cross-system integration tests of all three components to be performed in controlled environments, without interfering with production services. In this paper we discuss the design and implementation of the LifeCycle agent. We describe how it is used for small-scale debugging and validation tests, and how we extend that to large-scale tests of whole groups of sub-systems. We show how the LifeCycle agent can emulate the action of operators, physicists, or software agents external to the system under test, and how it can be scaled to large and complex systems.

    One of the biggest challenges that face Earth scientists is the resource discovery, access, and sharing in a desired fashion. EarthCube is targeted to enable geoscientists to address the challenges by fostering community-governed efforts that develop a common cyberinfrastructure for the purpose of collecting, accessing, analyzing, sharing and visualizing all forms of data and related resources, through the use of advanced technological and computational capabilities. Here we design an Enterprise Architecture (EA) for EarthCube to facilitate the knowledge management, communication and human collaboration in pursuit of the unprecedented data sharing across the geosciences. The design results will provide EarthCube a reference framework for developing geoscience cyberinfrastructure collaborated by different stakeholders, and identifying topics which should invoke high interest in the community. The development of this EarthCube EA framework leverages popular frameworks, such as Zachman, Gartner, DoDAF, and FEAF. The science driver of this design is the needs from EarthCube community, including the analyzed user requirements from EarthCube End User Workshop reports and EarthCube working group roadmaps, and feedbacks or comments from scientists obtained by organizing workshops. The final product of this Enterprise Architecture is a four-volume reference document: 1) Volume one is this document and comprises an executive summary of the EarthCube architecture, serving as an overview in the initial phases of architecture development; 2) Volume two is the major body of the design product. It outlines all the architectural design components or viewpoints; 3) Volume three provides taxonomy of the EarthCube enterprise augmented with semantics relations; 4) Volume four describes an example of utilizing this architecture for a geoscience project.

    Cell and molecular biological investigations have greatly contributed to our understanding of receptor and effector mechanisms in sensory, neuronal, and endocrine cells. A fascinating aspect of this line of research is how such mechanisms have evolved and how they interact with each other. As shown in this contribution, the vertebrate pineal organ is an interesting model to study these problems, because it undergoes a conspicuous transformation during phylogeny, comprises two well-chraracterized receptor mechanisms (photoreception and adrenoreception), and acts upon its targets via neuronal and neuroendocrine signals.

    Firms assume increasing importance within co-operative modes of regional and urban governance. Further to just filling gaps left by the retreat of the welfare state, firms recognise the impact of their regional and local business environment on their performance, especially when it comes to attracting and retaining highly-skilled personnel. As an introduction to this issue, this contribution introduces the basic concept of corporate social responsibility and its regional variation, corporate regional responsibility.

  1. Fehler begehen - Mathematik verstehen Über die Bedeutung von Fehlern für das Verstehen

    NASA Astrophysics Data System (ADS)

    Käser, Udo

    Auch wenn eine historisch oder systematisch umfassende Darstellung zur Fehlerthematik bislang nicht vorliegt, ist die Idee, einer Fehleranalyse unter der Leitfrage, welche Fehler von Schülerinnen und Schülern aufgrund welcher epistemologischen Überzeugungen begangen werden, zentralen Raum für die Betrachtung von Verstehensprozessen einzuräumen, nicht neu. So ist es geradezu ein Charakteristikum einer modernen konstruktivistischen Didaktik, die eigenen Fehler von Lernenden als ihre individuellen Lerngelegenheiten zu begreifen, die einen wichtigen Motor für den subjektiven Lernfortschritt bilden. Diese Sichtweise wurzelt aus psychologischer Perspektive in Analysen in der Tradition Piagets, der in Abkehr von einer quantitativen, psychometrischen Beschreibung kognitiver Prozesse, wie sie sich zum Beispiel in Intelligenztheorien nach Binet findet, qualitativ zu beschreiben versuchte, in welcher Weise Kinder und Jugendliche denken und urteilen. Doch auch schon in der klassischen Philosophie sind entsprechende Ansätze zu finden. Prominente Beispiele hierfür sind die Idolenlehre Bacons und die Ideenlehre Platons.

  2. Evolução química de galáxias HII anãs

    NASA Astrophysics Data System (ADS)

    2003-08-01

    Galáxias HII anãs são galáxias de baixa massa, com alto conteúdo de gás, e se encontram em uma fase intensa de formação estelar. A taxa de formação estelar está tão alta nestas galáxias que não pode ter se mantido durante sua vida inteira. O tempo máximo de duração do episódio atual de formação estelar deve ser no máximo de algumas dezenas de milhões de anos, bem inferior à idade destas galáxias. Isto leva naturalmente a idéia de que já aconteceram surtos anteriores. Abundâncias químicas oferecem uma ferramenta poderosa para investigar a história evolutiva destas galáxias, porque aumentam de geração em geração estelar. O hidrogênio, o oxigênio, o nitrogênio produzem algumas das linhas mais importantes em um gás foto-ionizado, permitindo a determinação das abundâncias destes elementos facilmente. A dispersão das abundâncias em oxigênio e nitrogênio é significativa, sendo maior que os erros observacionais. O oxigênio é produzido em estrelas massivas, que explodem quase instâneamente, enquanto o nitrogênio é produzido em estrelas de massa intermediária, que só o liberam depois de um atraso de @ 500 mihões de anos. Construímos um modelo de evolução química semi-analítico, utilizando rendimentos empíricos baseados nas abundâncias observadas destes dois elementos. Conseguimos através deste modelo rudimentar explicar nas galáxias de mais baixas metalicidades as abundâncias de oxigênio e de nitrogênio, assim como a dispersão dos dados observacionais devida a formação estelar descontínua, e isto com um número baixo de surtos (1 ou 2, no máximo 3).

    Espera-se que o educando ao final da educação básica, adquira uma compreensão atualizada das hipóteses, modelos e formas de investigação sobre a origem e evolução do Universo em que vive. O presente trabalho tem como principal objetivo compreender dentre três práticas pedagógicas adotadas no Ensino de Astronomia, na terceira série do Ensino Médio, da Escola Estadual Colônia dos Pescadores, qual melhor cumpre o papel de formação e aprendizagem para vida. A pesquisa preliminar foi através de um questionário onde o intuito foi diagnosticar o conhecimento já existente acerca do tema em questão. O questionário é composto de vinte questões dissertativas e objetivas, onde os educandos das três turmas envolvidas o responderam. Este trabalho utiliza as seguintes metodologias: a tradicional, onde o professor é um repassador de informações, fazendo uso exclusivo de lousa e giz; a segunda também de forma tradicional, porém com auxílio de multimídia para desenvolvimento das aulas e aterceira sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervenções necessárias. Ao final do trabalho os alunos responderão novamente o questionário inicial para diagnosticar dentre as três metodologias utilizadas qual apresentou melhor resultado. Os resultados preliminares obtidos, já podem ser observados e, dos 119 alunos entrevistados, as respostas obtidas são as mais diversas e evidenciam que a grande maioria nunca teve em sua vida escolar o tema Astronomia. Ao serem questionados se já haviam estudado Astronomia as respostas foram: turma A: sim 43%; turma B: sim: 21%; turma C: sim: 24%. Porém quando questionados a respeito do significado de Astronomia observou-se que: turma A: 100% de acertos; turma B: 64% acertos; turma C: 84% de acertos, demonstrando claramente a aprendizagem em diferentes esferas, não dependendo unicamente da escola. Até o presente momento, verificou-se que há interesse em

    Introdução: A satisfação com a profissão médica tem sido apontada como um fator essencial para a qualidade assistencial, o bemestar dos doentes e a estabilidade dos sistemas de saúde. Estudos recentes têm vindo a enfatizar um crescente descontentamento dos médicos, principalmente como consequência das alterações das relações laborais.Objetivos: Avaliar a perceção dos médicos de formação específica em Portugal, sobre as expectativas e grau de satisfação com a profissão, especialidade e local de formação; razões da insatisfação e intenção de emigrar.Material e Métodos: Estudo transversal. A colheita de dados foi efetuada entre Maio e Agosto de 2014 através de um Inquérito online sobre a âÄúSatisfação com a EspecialidadeâÄù.Resultados: De uma população total de 5788 médicos, foram obtidas 804 respostas (12,25% do total de médicos internos). Desta amostra, 77% das respostas correspondem a internos dos três primeiros anos de formação. Verificou-se que 90% dos médicos se encontram satisfeitos com a especialidade, tendo-se encontrado também níveis elevados de satisfação com a profissão (85%) e local de formação (86%). Por outro lado, constatou-se que estes diminuíam com a progressão ao longo dos anos de internato. A avaliação global sobre o panorama da prática médica foi negativa e 65% dos médicos responderam que consideram emigrar após conclusão do internato.Conclusão: Os médicos internos em Portugal apresentam níveis positivos de satisfação com a sua profissão. No entanto, a sua opinião sobre o panorama da Medicina e os resultados relativos à intenção de emigrar alertam para a necessidade de tomada de medidas para inverter este cenário.

    Acredita-se que quando duas estrelas de nêutrons coalescem, elas, eventualmente, formam um buraco negro com massa igual a soma das massas dos objetos originais. Durante a formação do buraco negro, o espaço-tempo em torno do sistema sofre perturbações que se propagam na forma de radiação gravitacional. A forma de onda associada a radiação gravitacional, durante este estágio, aproxima-se a uma senóide exponencialmente amortecida. Este tipo de sinal é conhecido como "ringdown", e seu comportamento e parametrização são muito bem conhecidos. Neste trabalho, simulamos computacionalmente sinais provenientes do "ringdown" de buracos negros, com a finalidade de testar o desempenho do detector de ondas gravitacionais Mario Schenberg em observá-los, quando entrar em funcionamento. Este primeiro teste teórico ajudou-nos a criar estratégias de detecção de sinais imersos no ruído instrumental. Calculamos a relação sinal-ruído como uma função da frequência, bem como sua integral dentro da faixa de sensibilidade do detector. Os resultados obtidos mostraram que o detector Schenberg terá sensibilidade suficiente para detectar este tipo de sinal, proveniente de fontes astrofísicas localizadas dentro de um raio de ~100kpc.

    A natureza do contínuo UV/ótico em rádio-galáxias é muito importante para o seu entendimento. Em baixos redshifts existem evidências de que muitas delas são dominadas no ótico por luz de estrelas velhas, características de galáxias early-type e em altos redshifts a característica dominante é um excesso de luz no UV, freqüentemente associado com estruturas que estão alinhadas aos eixos das estruturas rádio em grande escala. Inicialmente esse excesso foi interpretado como devido a episódios intensos de formação estelar nas galáxias hospedeiras. Entretanto, as descobertas dos alinhamentos entre as estruturas UV e rádio modificaram essa idéia. Foi proposto que a formação estelar é iniciada pela passagem do jato rádio através do meio interestelar das galáxias hospedeiras. A natureza do excesso UV começou a ser compreendida em um estudo detalhado do continuo ótico da 3C321, onde se concluiu que o contínuo desta galáxia tem origem multicomponente, com contribuições de populações velhas e intermediárias, de luz espalhada oriunda de um quasar obscurecido e do contínuo nebular. No presente trabalho estudamos a população nuclear e extranuclear de uma amostra de 24 rádio-galáxias, utilizando espectros óticos de fenda longa, com alta razão sinal/ruído. Através do método de síntese espectral de populações estelares, foram estimadas as contribuições de populações estelares de diferentes idades (e de um contínuo tipo lei de potência devido a um AGN, FC) para a luz integrada das galáxias, em 4020Å. As principais conclusões deste trabalho são: apenas quatro dos objetos estudados têm contribuições significativas (maiores do que 10%) das populações de 100 milhões de anos ou mais jovens (ou de FC) ao longo da região espacial estudada (6 kpc centrais); nenhuma das rádio-galáxias de tipo FRI estudadas tem contribuição significativa destas populações ao longo desta região; duas (de oito) de tipo FRII tem contribui

    O conteúdo desse texto surgiu de uma apresentação de mesmo título que fiz na XXXI Reunião Anual da Sociedade Astronômica Brasileira (SAB) em 2005. Esse tema foi inspirado originalmente pela minha participação no "2nd UIPAP International Conference on Women in Physics" realizado entre 23 e 25 de maio de 2005 no Rio de Janeiro. Essa é uma conferência internacional que acontece de três em três anos, sendo que a primeira ocorreu em 2002 na cidade de Paris, França. Participei dessa conferência como membro da delegação da Sociedade Brasileira de Física e um dos trabalhos que apresentei versava sobre a situação das mulheres na Astronomia brasileira, cujos resultados principais discorro a seguir. A situação das astrônomas, baseada nos dados dos sócios da SAB coletados no final de 2004, é comparada com a das físicas brasileiras e também com as nossas colegas americanas. Os dados identificam ainda uma maior evasão da carreira por parte das mulheres do que os homens. Alguns dos possíveis motivos da evasão são discutidos, como o desejo de constituir família e/ou isolamento. Resultados um tanto preocupantes com relação à distribuição de bolsas de produtividade do CNPq também são apresentados. As principais discussões e estratégias recomendadas nesse congresso são mencionadas de forma resumida ao final.

  10. Populações estelares do bojo galáctico

    NASA Astrophysics Data System (ADS)

    Escudero, A. V.; Costa, R. D. D.; Maciel, W. J.

    2003-08-01

    Os estudos mais recentes do bojo galáctico têm enfocado essencialmente as abundâncias químicas de elementos pesados, como o ferro, obtidos a partir das estrelas nas regiões centrais da galáxia. Elementos leves, como hélio, nitrogênio, oxigênio e argônio ainda são pouco estudados nestas regiões, devido à difícil determinação de suas abundâncias a partir de estrelas. Nestas condições as nebulosas planetárias desempenham um importante papel, pois permitem a determinação de abundâncias destes elementos usando técnicas de espectroscopia nebular. Neste trabalho, reportamos a análise das abundâncias químicas de uma nova amostra de nebulosas planetárias do bojo, bem como os resultados preliminares de um código numérico destinado a modelar a evolução química desta região. Usamos como vínculos observacionais os resultados obtidos das nebulosas planetárias, bem como de abundâncias estelares da região do bojo, obtidas da literatura. A partir deste modelo da evolução química e dos vínculos observacionais foi possível fazer um diagnóstico mais preciso das populações que constituem o bojo galáctico. O estudo destas populações que compõem a região central de nossa galáxia é de extrema importância para o maior entendimento da evolução química e dinâmica da galáxia como um todo. Por isto, verificamos a importância dos modelos de formação simples e mista utilizados para explicar características da população da região central da galáxia. Algumas destas características são: uma grande dispersão nos valores das abundâncias químicas e um grande espalhamento nas correlações entre as abundâcias de nitrogênio e oxigênio. Estas peculiaridades são dificilmente reproduzidas por modelos de formação simples, e portanto são importantes indícios da validade dos modelos de formação mista, tais como um rápido colapso do bojo seguido de uma evolução secular.

    2003-08-01

    Alguns fenômenos de outbursts em Be-X sugerem a existência, mesmo que temporária, de um disco de acresção quando da passagem do objeto compacto pelo periastro orbital. Neste trabalho avaliamos a possibilidade de formação do disco de acresção em sistemas Be+estrela de neutrons e Be+anã branca, e a influência da excentricidade orbital na ocorrência deste fenômeno. Utilizamos a expressão analítica para o momento angular específico da matéria constituinte de um meio em expansão lenta, como é o caso do disco circunstelar das estrelas Be, proposta por Wang(1981), sob a condição básica de que o raio de circularização deva ser maior do que o raio de Alfvén. Concluímos que existe um limite para o período orbital do sistema acima do qual não é possível a formação do disco de acresção, e que este valor aumenta para sistemas com excentricidade orbital maior.

  12. Das Blüte-Bestäuber-Netz auf Brachflächen : biozönologische Untersuchung zur Bedeutung von Brachen in einer intensiv genutzten Agrarlandschaft

    In der vorliegenden Dissertation wird die Bedeutung von Brachen für Artenvielfalt und Stabilität von Blüte-Bestäuber-Nahrungsnetzen in agrarisch genutzten Landschaften anhand ausgewählter blütenbesuchender Insektengruppen (Syrphidae, Lepidoptera) untersucht. Die Freilandarbeiten fanden von 1998-2000 im Raum der Feldberger Seenlandschaft, Mecklenburg-Vorpommern, statt. Es werden die beiden Hauptnahrungsquellen Nektar und Pollen betrachtet, dabei fanden Untersuchungen zur Intensität der Blüte-Bestäuber-Interaktion auf Stilllegungsflächen, zum flächenbezogenen quantitativen Nektarangebot im Jahresverlauf, zur individuellen Pollennutzung bei Syrphiden und zur Breite und Überlappung der Nahrungsnischen bei den dominanten Arten Episyrphus balteatus, Metasyrphus corollae, Syritta pipiens und Sphaerophoria scripta statt. Im Ergebnis zeigt sich eine hohe Bedeutung der Brachflächen für die Stabilität des Blüte-Bestäuber-Netzes, während die Diversität von anderen, eher landschaftsbezogenen Faktoren abhängig ist. This dissertation examines the importance of fallow land for the diversity and stability of pollination webs in agricultural landscapes as exemplified by selected groups of anthophilous insects (syrphidae and lepidoptera). The field studies were carried out between 1998 and 2000 in the Feldberg lakeland area in the north-east German State of Mecklenburg-Western Pomerania. Observations were made of nectar and pollen as the two main sources of food. Studies were conducted into the intensity of plant-pollinator interaction in set-aside areas, the site-specific quantity of nectar available during the vegetation period and the individual pollen intake of syrphid flies. Different methods were employed to establish the breadth of the trophic niches among the predominant species (Episyrphus balteatus, Metasyrphus corollae, Syritta pipiens and Sphaerophoria scripta) and the extent to which they overlapped. The studies showed that, while fallow land is very important for the stability of plant-pollinator food webs, their diversity depends on other factors that are more closely related to the landscape.

    Elektronenröhren standen wegen ihrer Rüstungsrelevanz nach Kriegsende unter dem Vorbehalt der Besatzungsmächte. Unter dem Druck eigener materieller Defizite erlaubte und initiierte die sowjetische Besatzungsmacht Entwicklungen dazu eher als die westlichen Alliierten. Daraus resultierten bemerkenswerte Innovationen und Vorsprünge im Gebiet von Miniaturröhren.

    Hospitalizations represent an important share of healthcare, due to both the complexity of actions and the financial volume applied. This descriptive-exploratory investigation had the purpose to identify and describing the physical and financial production of hospitalizations performed in a school hospital in the state of São Paulo, from 1996 to 2003, focusing the specialties of surgical clinic, medical clinic, pediatrics and obstetrics. Data collection was performed by searching the official databanks of the studied institution. In that period, a global 8.5% reduction in the frequency of admittances and a 78.4% increase in the financial resources were observed. Surgical clinic, with more expensive procedures, increased its admittances; the production in obstetrics showed the lowest variation. The increasing incorporation of technology, the demands from regional users and the migration of users from the supplementary system to the SUS may justify the variation of production in the different specialties.

    In 2010, under the guidance of the DGAI (German Society of Anaesthesiology and Intensive Care Medicine) and DIVI (German Interdisciplinary Association for Intensive Care and Emergency Medicine), twelve German medical societies published the “Evidence- and Consensus-based Guidelines on the Management of Analgesia, Sedation and Delirium in Intensive Care”. Since then, several new studies and publications have considerably increased the body of evidence, including the new recommendations from the American College of Critical Care Medicine (ACCM) in conjunction with Society of Critical Care Medicine (SCCM) and American Society of Health-System Pharmacists (ASHP) from 2013. For this update, a major restructuring and extension of the guidelines were needed in order to cover new aspects of treatment, such as sleep and anxiety management. The literature was systematically searched and evaluated using the criteria of the Oxford Center of Evidence Based Medicine. The body of evidence used to formulate these recommendations was reviewed and approved by representatives of 17 national societies. Three grades of recommendation were used as follows: Grade “A” (strong recommendation), Grade “B” (recommendation) and Grade “0” (open recommendation). The result is a comprehensive, interdisciplinary, evidence and consensus-based set of level 3 guidelines. This publication was designed for all ICU professionals, and takes into account all critically ill patient populations. It represents a guide to symptom-oriented prevention, diagnosis, and treatment of delirium, anxiety, stress, and protocol-based analgesia, sedation, and sleep-management in intensive care medicine.

    Edwin Hubble discovered in 1929 the redshift-distance relation (Hubble relation) of extragalactic objects, which is interpreted as the expansion of the Universe. Today the value of the expansion rate, the so-called Hubble parameter H0, is still a matter of debate, because no universal extragalactic distance scale exists. In this article an overview is given about methods to determine extragalactic distance and the influence of the results on H0.

    The argument proposed by Wason et al. that the conversion of magnitudes from a scale (e.g. Ms or mb) to another (e.g. Mw), using the coefficients computed by the general orthogonal regression method (Fuller) is biased if the observed values of the predictor (independent) variable are used in the equation as well as the methodology they suggest to estimate the supposedly true values of the predictor variable are wrong for a number of theoretical and empirical reasons. Hence, we advise against the use of such methodology for magnitude conversions.

    People more and more recognize climate change as one of the main environmental problems and the term `carbon footprint' (CF) has become popular and is now in widespread use. In this paper, the CF concept has been applied to analyse average per capita household Greenhouse Gas (GHG) emissions in Latvia. We explore household CF in housing (heating and electricity consumption), transport, food and goods and service sectors, which are the main household environmental pressure areas. This paper provides an understanding of both direct and indirect (embodied) GHG emissions. Results from the study suggest that the average Latvian exceeds its global fair share of GHG emissions - the average per capita GHG in 2006 was 4.35 t CO2e. The highest household emissions arise from housing (37%), mobility (26%) and food consumption (25%), goods and services together account only for 12% of total household GHG emissions. This study, however, does not cover capital investments in infrastructure (roads, public buildings etc.) which could increase total emission by almost a ton. The study emphasizes that attention must be paid to the lifestyles, infrastructure and institutions that result in considerable amounts of carbon being locked up in the household activities through which people meet their everyday needs. The findings also indicate that policies should be targeted at the segments in society responsible for the highest carbon footprints, ie. housing, food and mobility.

  3. Lemaître, the expanding universe, and the cosmological constant (German Title: Lemaître, das expandierende Universum und die kosmologische Konstante )

    NASA Astrophysics Data System (ADS)

    Roessler, Kurt

    The scientific and human relations of Albert Einstein and Georges Lemaître are discussed. In 1927 the later had interpreted the general theory of relativity for a model of an expanding cosmos using a positive value of the cosmological constant. In the three open questions between them: expansion of cosmos, primordial state of a quantum vacuum (``primeval atom''), importance of the cosmological constant for vacuum energy, Lemaître finally won over the heavily opposing Einstein. The philosophical and ontological tendency of Einstein's thinking was contrasted with the strict epistemological line of the catholic priest Lemaître. The dramatic changes between friendship and controversy finally led to a diminution of Lemaître's reputation as ``Darwin of Cosmology''. In that case, the late Einstein proved to be a hindrance rather than a promoter of evolution in cosmology.

    The Ruhr area has advanced to the largest university region in Germany - often unnoticed within and outside. At the same time scientific institutions have become a major economic factor. Because of the higher and extra-university research institutions about 2.5 billion euros are effective as a demand potential in the region. 1.7 billion euros of this amount are directly associated with investments and operating expenditures of the scientific institutions as well as consumptions of employees and students. Additional 770 million euros result in revenues of many branches such as trade, housing, gastronomy sector, handcraft industry etc. It should not be underestimated that higher and extra-university research institutions generate with their research activities particular funding from the European Union or the rest of Germany for benefit of the region. Each euro spent by the state government for basic funding creates 39 cents third-party funding. These regional-economic effects result in noticeable employment impacts within the region. Around 25,000 people are directly employed in higher and extra-university research institutes or student unions (Studierendenwerke), about 22,000 jobs in other economic sectors are ensured or created by the induced demand. Science has thus become an important economic factor and represents an essential counterbalance to employment decline in shrinking industries of the region. The specific inclusion of science in a regional development strategy and targeted relining with appropriate measures to strengthen the science creates therefore an effective starting point for the design of structural change.

  6. An analysis of seasonal changes in STE using measurements from the TOPSE campaign and the Beryllium-7 distribution from a calculation driven by the GEOS-3 DAS.

    Measurements of tropospheric ozone (O3) between 30\\deg and 70\\deg N show springtime maxima at remote locations. The contribution of seasonal changes in stratosphere-troposphere exchange (STE) to these maxima was investigated using measurements from the Tropospheric Ozone Production about the Spring Equinox Experiment (TOPSE) campaign and the Beryllium-7 (7Be) distribution from a calculation driven by fields from the Goddard Earth Observing System Data Assimilation System. Comparison with TOPSE measurements revealed that upper tropospheric model-calculated 7Be mixing ratios were reasonable (a change from previous calculations) but that lower tropospheric mixing ratios were too low most likely due to an overestimation of scavenging. Temporal fluctuations were well captured although their amplitudes were often underestimated. Analysis of O3 measurements indicated that mixing ratios increased by 5-10% per month for θ < 300 K (the underworld) and by 10-15% per month for θ > 300 K (the tropospheric middleworld). 7Be mixing ratios decreased with time for θ < 290 K and increased with time for θ > 300 K. Model-calculated middleworld increases of 7Be were a factor of 2 less than measured increases. 7Be with a stratospheric source (strat-7Be) increased by 4.6-8.8% along TOPSE flight paths within the tropospheric middleworld. Increases in strat-7Be were not seen along TOPSE flight paths in the underworld. Assuming changes in O3 with a stratospheric source are the same as changes in strat-7Be and that 50% of O3 is produced in the stratosphere, changes in STE explain 20-60% of O3 increases in the tropospheric middleworld and less than 30% of O3 increases in the underworld.

    The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) was ratified in 1982. This Convention was established in the light of a rapidly developing krill fishery in the 1970’s. The objectives of the Convention are the rational use of marine living resources as well as the conservation of the resources and the marine ecosystem. Establishing the principle of the ecosystem approach has been rather progressive in fisheries conventions. From the bery beginning CCAMLR had to deal with problems of over-exploited fish stock from the unregulated fishery of pre-CCAMLR times. Antarctic cod and icefish stock were already heavily harvested or even showed signs of overfishing. Conservation measures and the closure of subareas for several years did not always lead to satisfactorily results. While some stock of icefish recovered to the extent, that a new fishery on a low level could be re-opened, other icefish stocks and especially Antarctic cod stocks have not recovered from this early depletion. A new dimension in the fishery developed in the mid 1990’s, when very conservative conservation measures were introduced for the Dissostichus (toothfish), but due to the high commercial value a large illegal fishery developed rapidly in the Convention area. One additional problem of managing the longline fishery for toothfish is the by-catch and incidental mortality of sea-birds, for which special measures were established to avoid sea-bird mortality. The compliance with the measures and the elimination of the illegal fishery require strong actions of the Commission, the political decision-making body of CCAMLR. A future challange for CCAMLR could be the potentially expanding krill fishery. In the understanding of a precautionary approach, the scientific body of CCAMLR has already started to collect biological data and develop management and monitoring models for this fishery.

    Hardly any other city in North Rhine-Westphalia has such a green image as the city of Münster. It embodies the image of a livable city in Germany. Other North Rhine-Westphalian cities also work on their external perception and are approaching the task of getting a greener image for themselves in many ways. A central question is how it is done precisely and whether urban green infrastructure can be a locational factor to affect location-based marketing. This article deals with the strategies of various cities in North Rhine-Westphalia.

  11. Las propiedades de las estrellas extrañas en el marco de una nueva ecuación de estado para la materia extraña

    NASA Astrophysics Data System (ADS)

    Lugones, G.; Benvenuto, O. G.

    Se estudian las propiedades generales de las estrellas constituídas por materia extraña (ME) en el marco de una nueva ecuación de estado (EOS) en la que consideramos la masa de los quarks como dependiente del número medio de bariones por unidad de volumen. Se asume esta dependencia de forma que los quarks sean livianos (pesados) a densidades altas (bajas). En esta aproximación, la EOS de la ME es similar a la predicha por el modelo de la Bolsa del MIT, pero es significativamente mas dura a bajas densidades. Esta propiedad modifica las propiedades de las estrellas extrañas en forma notable. Encontramos que, con esta nueva EOS, los objetos pueden ser más masivos que en el caso de la EOS de la bolsa del MIT y que, además, pueden presentar mayores redshifts gravitatorios en hasta un 10%. En el caso de las oscilaciones radiales de estos objetos, calculamos la relación período vs. redshift gravitacional y encontramos una expresión analítica simple para el caso de las oscilaciones de objetos de baja masa. Encontramos que, aún con hipótesis muy diferentes en cuanto a la ecuación de estado de la materia extraña, las propiedades generales de estos objetos no se ve afectada en forma fundamental, y, por lo tanto, no deberían ser muy diferentes de las aquí expuestas.

    Apresentamos medidas nas bandas J, H e K de cerca de 90 galáxias em 34 grupos compactos. Através da combinação dos novos dados, com dados obtidos na literatura para a banda B, investigamos como as luminosidades, cores, tamanhos e massas das galáxias em grupos compactos foram afetadas por processos dinâmicos, e como essas diferem de galáxias em ambientes menos densos. Uma comparação dos novos valores obtidos com aqueles listados no catálogo 2MASS, mostram que para 50 galáxias estudadas em comum, as diferenças nas magnitudes J, H e K estão dentro dos erros fotométricos. Através da construção dos diagramas de cor (J-H x H-K e B-H x J-K), percebemos que as galáxias em grupos compactos ocupam posições no diagrama diferentes das posições de galáxias em campo ou em aglomerados, sendo mais parecidas com as posições ocupadas por galáxias HII, ou com excesso de poeira, acreditamos que tal deslocamento é derivado do aumento da taxa de formação estelar.

    É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite otimizar a divulgação e o ensino não formal de Astronomia aliando a adequação do conteúdo à expectativa das pessoas. Nesse intuito, nosso trabalho busca mapear que assuntos da Astronomia despertam mais a atenção e o interesse das pessoas e o quanto disso é estimulado pela mídia, que freqüentemente aproveita-se desse interesse de forma sensacionalista, trazendo contribuições positivas e negativas. Para esta avaliação, utilizamos as pesquisas específicas e de caracterização do público que freqüentou o MAst nos anos de 2001 a 2003, pesquisa das matérias de Astronomia veiculadas na mídia escrita da cidade do Rio de Janeiro no mesmo período, além da base de dados do programa Pergunte a um astrônomo, realizado no Observatório Nacional nos anos de 1997 a 1999. Para a análise dos dados, dividimos as perguntas em dez categorias, cada uma com suas subcategorias, tomando como referência as divisões, comissões e grupos de trabalho da IAU. Apresentamos neste trabalho os resultados dessa pesquisa, que incluem, entre outros, a predominância de questões nas categorias Observação do Céu e Sistemas Planetários enquanto nos jornais dominam as notícias de Sistemas Planetários e Espaço & Astronáutica. Outro resultado interessante indicou que as dúvidas de crianças do ensino fundamental se concentram em algumas categorias enquanto as questões de adultos são mais distribuídas por todas as categorias. Os resultados dessa pesquisa serão aplicados diretamente no aperfeiçoamento das atividades do Programa de Observação de Céu, bem como na elaboração de novos projetos e eventos realizados no MAst.

    2011-12-01

    O presente trabalho, sobre a intervenção de metodologias de ensino, foi desenvolvido na Escola Estadual Colônia dos Pescadores, na cidade de Caraguatatuba - SP, em três turmas do terceiro ano do Ensino Médio, perfazendo um total de 119 educandos, entre 16 e 19 anos. Antes de iniciar-se a intervenção, um questionário de vinte perguntas objetivas e dissertativas foi desenvolvido, aplicado pelo professor da classe, que ministrou as aulas correspondentes. Este questionário foi o mesmo em todas as três classes com o objetivo de diagnosticar o conhecimento prévio dos alunos sobre Astronomia. Começando a intervenção nas turmas, o professor envolvido usou três diferentes metodologias de ensino: (A) em forma de seminários, elaborados e apresentados pelos alunos, nos quais o professor fazia apenas as intervenções necessárias, (B) na forma tradicional, com a ajuda de multimídia para o desenvolvimento das aulas e a terceira (C) a tradicional, fazendo uso exclusivo de lousa e giz. No final do trabalho os alunos responderam o mesmo questionário novamente, de modo que os três métodos utilizados puderam ser comparados. Os resultados apresentados após a intervenção foram melhores que os resultados iniciais indicando a ocorrência de uma aprendizagem significativa. Quando os estudantes foram inicialmente questionados sobre quantos planetas existem no nosso sistema solar, a classe A obteve 39% de respostas certas, a classe B 48% e a classe C 46%, mas após o desenvolvimento das atividades, as classes obtiveram respectivamente 94%, 97 % e 90% de aproveitamento. No término do bimestre, foi sugerido aos educandos que elaborassem uma história em quadrinhos, a qual serviu para averiguar se os conceitos inicialmente observados foram alterados e se novos foram agregados. A análise das histórias foi dividida em três partes: Criatividade; Temas abordados; Emprego correto dos conceitos estudados. Ao final quatorze histórias foram confeccionadas. O aprendizado

  15. A distribuição de velocidades na linha de visada em galáxias barradas vistas de face

    Gadotti, D. A.; de Souza, R. E.

    2003-08-01

    Com o objetivo de realizar um estudo cinemático da componente vertical de barras em galáxias, obtivemos espectros de fenda longa de alta razão S/N ao longo dos eixos maior e menor de 14 galáxias barradas vistas de face, nos telescópios de 1.52m do ESO em La Silla, Chile, e de 2.3m do Steward Observatory em Kitt Peak, Arizona. Estes dados nos permitiram determinar a distribuição de velocidades das estrelas ao longo do eixo vertical das barras e discos destes sistemas, tanto no centro como em pontos que distam cerca de 5 e 20 segundos de arco do núcleo, correspondendo a distâncias de cerca de 0.7 e 2.8 kpc, respectivamente. Desta forma, a variação radial da distribuição de velocidades também pôde ser avaliada. Este tipo de análise tem raros exemplos na literatura por ser caro em termos de tempo de telescópio. Entretanto, é de fácil justificativa, considerando que traz novas informações que podem ser utilizadas para aperfeiçoar modelos teóricos acerca da formação e evolução de galáxias. Um algoritmo por nós desenvolvido foi utilizado para obter as distribuições de velocidades como Gaussianas generalizadas (polinômios de Gauss-Hermite), o que traz um ingrediente a mais neste tipo de estudo que, tradicionalmente, se utiliza de Gaussianas puras, uma hipótese nem sempre razoável. Apresentaremos os resultados deste trabalho, que incluem um diagnóstico para a identificação de barras recém formadas, e testes para o modelo isotérmico de discos. Mostraremos que: (i) a escolha das estrelas padrão em velocidade, e dos parâmetros da Gaussiana, deve ser muito bem justificada já que tem influência significativa nos resultados; (ii) muitas galáxias apresentam uma depressão na dispersão de velocidades na região central, que pode estar associada a um disco interno; e (iii) a dispersão de velocidades é constante ao longo da barra, nos eixos maior e menor, mas cai substancialmente quando se passa da barra para o disco.

    Introdução: Analisar a prevalência das anomalias congénitas, detetadas no nascimento, entre filhos de gestantes adolescentes, enfatizando os tipos mais comuns e a época do diagnóstico. Material e Métodos: Estudo retrospetivo do tipo censo, no qual foram analisados todos recém-nascidos, vivos ou mortos, com peso superior a 500 g, de mulheres que tiveram o parto no Hospital São Paulo num período de seis anos. Os produtos da conceção portadores de anomalias foram identificados no período pré-natal ou através do exame físico pós-natal, segundo os critérios do Estudo Colaborativo Latino-Americano das Malformações Congênitas. Os resultados são apresentados de forma descritiva através de valores absolutos e relativos, calcula-se a prevalência das anomalias e comparam-se os diferentes grupos recorrendo a testes não paramétricos. Resultados: Foram analisadas 6 257 gestações, das quais 577 resultaram em recém-nascidos com alguma anomalia congénita identificada no nascimento (prevalência de 9,2%). Do total de gestações, 907 eram de adolescentes (idade inferior a 20 anos), para as quais se verificou uma prevalência de anomalias nos recém-nascidos de 9,9%. Comparando os recém-nascidos de adolescentes com os das mulheres com idade superior a 20 anos, apenas se encontrou diferença estatisticamente significativa para a prevalência dos defeitos do tubo neural (p = 0,027). Discussão: Observamos uma alta taxa de partos em adolescentes, acima das taxas dos países desenvolvidos. Observamos também alta frequência de anomalias congénitas em recém-nascidos, provavelmente por sermos um serviço terciário de referência. A elevada prevalência dos defeitos do tubo neural entre grávidas jovens pode ser explicada pela não suplementação pré-concecional de ácido fólico em gravidezes não planeadas, como é característico nas adolescentes.Conclusão: A prevalência e momento do diagnóstico das anomalias congénitas em rec

    Introdução: Este estudo pretende caracterizar os medicamentos usados numa Unidade de Cuidados Intensivos Neonatais portuguesa, avaliar a frequência do uso de fármacos off-label ou não licenciados de acordo com a informação disponível no Resumo das Caraterísticas do Medicamento e comparar resultados entre recém-nascidos prematuros e de termo.Material e Métodos: Um estudo retrospetivo transversal foi conduzido na nossa Unidade de Cuidados Intensivos Neonatais no primeiro semestre de 2013. Os dados das prescrições realizadas foram comparados com a informação pediátrica contida nos Resumos das Caraterísticas do Medicamento.Resultados: Analisámos 1011 prescrições respeitantes a 84 substâncias ativas, feitas em 218 admissões. Em 42,9% dos casos, os fármacos foram usados de acordo com a informação do Resumo das Caraterísticas do Medicamento; 27,9% dos fármacos eram aprovados para o período neonatal mas usados de forma off-label; medicamentos off-label para a idade neonatal foram usados em 10,1%, enquanto aqueles com estado de aprovação indeterminado ou contraindicados foram usados em 6,0% e 8,7% dos casos, respetivamente. As prescrições não licenciadas representaram 4,4% do total. Os recém-nascidos pré-termo receberam uma taxa superiorde fármacos usados de acordo com o Resumo das Caraterísticas do Medicamento (p < 0,0001), enquanto os de termo receberam mais fármacos off-label para dose/frequência (p < 0,0001) e contraindicados para recém-nascidos (p < 0,012).Discussão: Os prematuros receberam um número mediano de fármacos superior, o que se relaciona com o seu internamento mais prolongado. A principal razão para prescrições off-label foi a utilização de doses/frequências de administração diferentes das referidas no Resumo das Caraterísticas do Medicamento, reforçando a necessidade de atualização destes documentos. A manipulação dosmedicamentos é uma das causas para o seu uso não licenciado, enfatizando a falta de

    Basicamente, são propostos dois cenários de evolução quí mio-dinâmico para os sistemas esferoidais: (i) o hierárquico através da fusão e/ou acresção de sub-sistemas com ou sem surtos de formação estelar, e (ii) o colapso monolí tico dissipativo com formação estelar interrompida por um vento galáctico. Ambos, dentro de certos limites, conseguem explicar os gradientes internos de metalicidade estelar presentes nas galáxias elí pticas bem como a relação observada entre a metalicidade central e a massa (Mg20 vs. log sv0). No entanto, nenhum prevê uma variação interna para a razão de abundâncias Mg/Fe que indiretamente define a escala temporal da formação estelar. Empregamos a espectroscopia óptica de fenda longa com a finalidade de recuperar as histórias de formação estelar, de enriquecimento quí mico e da dinâmica dentro de determinadas regiões das galáxias. Os espectros de média resolução (FWHM = 7,1 Å) e escala angular de 1,092 arcsec/pixel foram coletados com o telescópio 1,60m do OPD/LNA. Comparamos nossas medidas de linhas de absorção com resultados espectrofotométricos de modelos de populações estelares simples - mais especificamente os í ndices do Sistema Lick como Mg2, Mg b, < Fe > e Hb - a fim de se investigar as variações internas de [Fe/H], [Mg/Fe] e idade. Para duas galáxias elí pticas, NGC 1052 e NGC 7796, pertencentes a ambientes de baixa densidade, encontramos uma variação radial da razão Mg/Fe decrescente do centro para fora em regiões de 0,6 e 1 raio efetivo respectivamente. Discutimos alguns cenários de enriquecimento quí mico para estas duas galáxias.

    Introducción: La valoración de las necesidades calóricas del paciente quemado se ha basado en la medición del gasto energético en reposo (GER) mediante calorimetría indirecta, no siempre disponible en las unidades de quemados, o en su estimación mediante el uso de ecuaciones predictivas. Objetivos: analizar la historia y estado del arte del uso de las ecuaciones predictivas de GER en el paciente quemado crítico, y determinar su validez. Métodos: revisión bibliográfica de estudios y revisiones en español y en inglés entre 1989 y 2013. Resultados: Se han diseñado más de 190 ecuaciones para estimar el gasto energético que pueden ser imprecisas por estar basadas en mediciones con metodología heterogénea y en grupos heterogéneos. Describimos los distintos parámetros que aplican las distintas fórmulas predictivas (factores de estrés y de actividad, superficie corporal quemada, tiempo desde la lesión, masa corporal magra), la influencia de la edad en el cálculo de las necesidades calóricas y las fórmulas más utilizadas en el momento actual. También describimos los artículos que evalúan exactitud de las fórmulas cuando se comparan con mediciones mediante calorimetría indirecta. Conclusiones: Las ecuaciones predictivas son poco precisas en general en el paciente quemado. Hasta que se desarrollen ecuaciones predictivas más precisas, recomendamos calcular los requerimientos nutricionales de los pacientes quemados basándose en la medición del gasto energético por calorimetría indirecta.

    Introdução: A hiperplasia congénita da suprarrenal por deficiência de 21-hidroxílase constitui uma das doenças hereditárias mais comuns. Resulta de diferentes mutações no gene CYP21A2 e, na maioria dos casos, a gravidade da doença correlaciona-se com a variação alélica do CYP21A2. O objetivo deste estudo foi descrever o espectro mutacional do CYP21A2 e avaliar a correlação genótipo-fenótipo numa coorte de doentes portugueses com deficiência de 21-hidroxílase. Material e Métodos: Estudo retrospetivo de 22 doentes com diagnóstico clínico de deficiência de 21-hidroxílase. Foi feita análise molecular do CYP21A2 e estabelecida a correlação genótipo-fenótipo. Resultados: Foi realizada genotipagem em 22 doentes não relacionados: 5 com a forma clássica perdedora de sal (idade média ao diagnóstico de 10,2 dias; mínimo 1, máximo 20 dias), 7 com a forma clássica virilizante simples (idade média ao diagnóstico de 3,5 anos; mínimo 0 dias, máximo 7 anos) e 10 com a forma não clássica (idade média ao diagnóstico de 5,7 anos; mínimo 4 anos, máximo 8 anos). Os defeitos genéticos mais frequentes nas formas clássicas foram o I2 splice (24%) e I172N (24%), seguindo-se o Q318X (16%) e deleções de genes (16%) e, na forma não clássica, o V281L (80%). Verificou-se uma concordância genótipo-fenótipo global de 81,8%. O genótipo permitiu prever adequadamente o fenótipo em 83,3%, 100% e 90% dos doentes com mutações compatíveis com a forma clássica perdedora de sal, clássica virilizante simples e não clássica, respectivamente. Discussão: A frequência de defeitos genéticos observados nos nossos doentes é comparável a estudos semelhantes. Observou-se, na maioria dos casos, uma boa correlação genótipo-fenótipo. Conclusões: A análise molecular do CYP21A2 fornece informação importante relativamente à gravidade da doença e no aconselhamento genético e pré-natal.

    The paper deals with the subject of the Four Seasons, exploring elements of Science and the Art in order to motivate students or public of museums of science and technology to understand it from their current cultural experiences and of old times. Physics joins to Astronomy to explain the phenomenon, while the use of Music and Painting make possible the immersion in the subject in way to many trips to the imagination capable to awake emotions.A proposal didactic is presented and justified for some consensus of the research in the area of teaching-learning of science, since that related to the persistent alternative conceptions concerning the causes of the changes observed at the different times of the year until the qualitative modelling of phenomena that appeals three-dimensional pedagogical models. Such proposal was developed in the activity named " Hiper interesting Talk: The Four Seasons, Science and Art" in the first Sunday of August/2003 in the Museum of Astronomy, MAST. O artigo trata do tema das Estações do Ano, explorando elementos da Ciência e da Arte como forma de motivar estudantes ou público de museus de ciência e tecnologia a compreendê-lo a partir de vivências culturais atuais e de outras épocas.

    Objetivo: Evaluar la adecuación de las ecuaciones de predicción para la estimación del gasto energético (GE), en comparación con el GE medido por calorimetría indirecta en una muestra de mujeres brasileñas y españolas con exceso de peso corporal. Métodos: Se trata de un estudio transversal con 92 mujeres adultas obesas [26 brasileñas —G1— y 66 españolas —G2— (20-50 años)]. Se evaluó el peso y la talla durante el ayuno para el cálculo del índice de masa corporal y las ecuaciones de predicción. Se evaluó el GE usando la calorimetría indirecta de circuito abierto con campana respiratoria. Resultados: En G1 y G2, se encontró que las estimaciones obtenidas por Harris-Benedict, Shofield, FAO/OMS/ ONU y Henry y Rees no difieren del GE estimado por calorimetría indirecta, la cual presentó valores más altos que las ecuaciones propuestas por Owen Mifflin -St Jeor y Oxford. Para G1 y G2 la ecuación predictiva que presentó valores más cercanos al valor obtenido por la calorimetría indirecta fue la FAO/OMS/ONU (7,9% y 0,46% subestimación, respectivamente), seguido por Harris-Benedict (8,6% y 1,5% subestimación, respectivamente). Conclusión: Las ecuaciones propuestas por la FAO/ OMS/ONU, Harris-Benedict, Shofield y Henry & Rees fueron adecuadas para estimar el GE en una muestra de mujeres brasileñas y españolas con exceso de peso corporal. Las otras ecuaciones subestimaron el GE.

    A nucleocosmocronologia emprega abundâncias de nuclídeos radioativos na datação de escalas de tempo astrofísicas. O 232Th é um nuclídeo radioativo com meia-vida de 14 Gano, enquanto que os dois isótopos mais abundantes do Eu são estáveis. O decaimento radioativo do Th modifica as razões de abundâncias [Th/Eu], fornecendo assim um meio de sondar a escala de formação das populações estelares. O objetivo deste trabalho é averiguar a possibilidade de estimar uma idade para o disco Galáctico através da nucleocosmocronologia do [Th/Eu] e investigar o nível de incerteza associado a esta estimativa. Para tanto, foi selecionada uma amostra de 20 estrelas anãs ou subgigantes de tipos espectrais F5 a G9, com -1,00 £ [Fe/H] £ +0,30 e idade(Gano) £ 13. As abundâncias de Th e Eu foram obtidas por síntese espectral das linhas localizadas em 4019,1 Å e 4129,7 Å, respectivamente. Uma comparação destas abundâncias com outros resultados da literatura demonstra que nossos valores apresentam dispersão 2 a 3 vezes menor que qualquer trabalho anterior. Os parâmetros atmosféricos e abundâncias dos elementos que contaminam as regiões espectrais destas linhas foram determinados por nós, de maneira totalmente autoconsistente, através de análise espectral detalhada diferencial em relação ao Sol. As idades estelares individuais foram determinadas através de curvas isócronas teóricas no diagrama HR. Foi realizada, então, uma análise cronológica dos gráficos [Th/Eu] vs. [Fe/H] e [Th/Eu] vs. idade. Os dados estelares foram comparados a curvas calculadas para 3 idades do disco Galáctico - 9, 12, 15 Gano - e foi estudada a sensibilidade à idade assumida no cálculo do ajuste destas curvas aos dados. Estas curvas foram calculadas com base num modelo analítico de evolução química da Galáxia que leva em consideração a formação de refugos, que são compostos pelos remanescentes da evolução estelar, pelos resíduos da formação de estrelas de

    Introdução: A lepra continua a ser uma das causas mais frequentes de neuropatia periférica. Apesar de tida como erradicada em Portugal, ainda se documenta no estudo neuropatológico de doentes com clínica de neuropatia periférica sem diagnóstico etiológico definido.Material e Métodos: Revisão dos casos neuropatia por doença de Hansen diagnosticados na Unidade de Neuropatologia do Centro Hospitalar do Porto no período de 1978 e 2013 atendendo ao género, idade, manifestações clínicas e achados neuropatológicos.Resultados: Foram identificados 21 doentes com diagnóstico neuropatológico de neuropatia por doença de Hansen, com predomínio do sexo masculino. A idade média ao diagnóstico foi de 52 anos, sendo a sintomatologia sensitiva predominante. O intervalo entre sintomatologia e diagnóstico oscilou entre 1 a 38 anos. Na maioria foi identificada forma tuberculoide em biópsia de nervo e detetados bacilos em pele e nervo em 44% dos casos.Discussão: A mononeurite é a forma mais comum de apresentação de hanseníase, podendo cursar com outras manifestações clínicas incluindo lesões cutâneas. A infeção pelo M. leprae lesiona fibras mielinizadas e não mielinizadas, com substituição do tecido nervoso por colagénio resultando em fibrose. O diagnóstico da lepra é apenas conseguido por estudo neuropatológico das lesões cutâneas e/ou nervo periférico, adjuvado pela identificação do bacilo.Conclusão: A doença de Hansen continua a ser um problema de saúde pública em áreas tropicais e, apesar de rara, ainda descrita em países ocidentais, devendo ser considerada como uma hipótese de diagnóstico na investigação de neuropatia periférica.

    The Rio Nhamundá is a poorly-known clearwater river draining the southern Guiana Shield of Brazil. In this study we report the findings of a preliminary ichthyological survey, focusing on catfishes (Siluriformes). We identify a total of 36 species (31 genera, seven families) from the Nhamundá, including 11 species already recorded from the river. Overall, our survey results show that even rapid surveys can provide important information on Amazon fish biodiversity, suggesting potential new species, providing range extensions for nominal species, and additionally highlighting taxa in need of taxonomic revision and genetic study. As well as the traditional forms of data collected on biodiversity surveys (i.e. preserved specimen vouchers), our study also provides "new" types of data in the form of DNA barcodes and images of fishes exhibiting colouration in life, information that will be invaluable in future work addressing difficult groups. O Rio Nhamundá é um rio de água clara, pouco conhecido, que drena parte do Escudo das Guianas em território brasileiro. Nesse estudo, nós reportamos os resultados de um levantamento ictiofaunístico preliminar dessa área, tendo como foco os bagres (Siluriformes). Nós identificamos um total de 36 espécies (31 gêneros, sete famílias) provenientes de nossa coleta, e adicionamos 11 espécies já conhecidas para o rio. De maneira geral, os resultados de nossa pesquisa mostram que mesmo levantamentos rápidos podem gerar informações importantes sobre a biodiversidade de peixes amazônicos, sugerindo potenciais espécies novas, ampliando a área de distribuição de espécies, além de apontar a necessidade de revisões taxonômicas e estudos genéticos para alguns taxa. Para além das formas tradicionais de dados coletados em pesquisas de biodiversidade (i.e. espécimes preservados), nosso estudo fornece "novas" formas de dados, como DNA barcodes e imagens com o padrão de coloração dos espécimes vivos, informa

    Obtivemos, como parte do programa de verificação científica do GMOS Sul, imagens profundas de três grupos de galáxias: G97 e G102 (z~0,4) e G124 (z = 0,17). Esses alvos foram selecionados a partir do catálogo de fontes extensas de Vikhlinin (1998), por terem luminosidades em raios X menores que 3´1043 ergs s-1, valor cerca de uma ou duas ordens de grandeza inferior ao de aglomerados de galáxias. O objetivo primário dessas observações é o estudo da evolução de galáxias em grupos. Grupos são ambientes menos densos que aglomerados, contêm a grande maioria das galáxias do Universo mas que, até o momento, foram estudados detalhadamente apenas no Universo local (z~0). Com esses dados efetuamos uma análise estatística da distorção na forma das galáxias de fundo (lentes gravitacionais fracas) como forma de inferir o conteúdo e a distribuição de massa nesses grupos apesar de que, em princípio, esse efeito não deveria ser detectado uma vez que os critérios de seleção adotados previlegiam sistemas de baixa massa. De fato, para G124 obtivemos apenas um limite superior para sua massa que é compatível com sua luminosidade em raios X. De modo contrário e surpreendente, os objetos G102 e G097, aparentam ter massas que resultariam em dispersões de velocidade maiores que 1000 km s-1, muito maiores do que se espera para grupos de galáxias. Com efeito, para G097 obtivemos, a partir de dados do satélite XMM, uma estimativa para a temperatura do gás intragrupo de kT = 2,6 keV, que é tipica de sistemas com dispersões de velocidade de ~ 600 km s-1, bem característica de grupos. Essas contradições aparentes entre lentes fracas e raios X podem ser explicadas de dois modos: i) a massa obtida por lentes estaria sobreestimada devido à superposição de estruturas massivas ao longo da linha de visada ou ii) a temperatura do gás do meio intra-grupo reflete o potencial gravitacional de estruturas menores que estariam se fundindo para formar uma

    Abstract The Rio Nhamundá is a poorly-known clearwater river draining the southern Guiana Shield of Brazil. In this study we report the findings of a preliminary ichthyological survey, focusing on catfishes (Siluriformes). We identify a total of 36 species (31 genera, seven families) from the Nhamundá, including 11 species already recorded from the river. Overall, our survey results show that even rapid surveys can provide important information on Amazon fish biodiversity, suggesting potential new species, providing range extensions for nominal species, and additionally highlighting taxa in need of taxonomic revision and genetic study. As well as the traditional forms of data collected on biodiversity surveys (i.e. preserved specimen vouchers), our study also provides "new" types of data in the form of DNA barcodes and images of fishes exhibiting colouration in life, information that will be invaluable in future work addressing difficult groups.

    Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

    Tem sido prática comum nos últimos anos estudar a distribuição de luminosidade em galáxias fazendo uso da informação contida em toda a imagem da galáxia, já que esta técnica tem se mostrado muito mais confiável do que o simples ajuste de perfis radiais de luminosidade. Através destes estudos bidimensionais, melhores resultados tem sido obtidos na análise e.g. do Plano Fundamental, de correlações entre os parâmetros estruturais de galáxias, de sub-estruturas como barras e anéis nucleares etc. Apresentamos um novo código bidimensional, o BUDDA, de análise estrutural de galáxias, que será disponibilizado para a comunidade. Desenvolvido por nós, o código determina os parâmetros estruturais de galáxias de forma prática e robusta, e pode ser aplicado genericamente em qualquer estudo sobre a formação, evolução e estrutura de galáxias. O programa ainda permite a avaliação direta de sub-estruturas, através de imagens residuais que são obtidas ao se subtrair, das imagens originais, bojo e disco sintéticos que melhor representam essas componentes da galáxia sob consideração. Será apresentada a forma de utilização do código, bem como séries de testes que atestam a sua funcionalidade. Além disso, os resultados da aplicação do código em uma amostra de 51 galáxias serão expostos como exemplo prático, e do seu enorme potencial de uso.

    Introducción: la morbimortalidad materna representa un problema de salud en los países en desarrollo, las causas de muerte obstétrica dependen de la región geográfica y de otros factores que incluyen la calidad de los servicios de salud. El objetivo de este estudio fue analizar las causas de morbilidad y mortalidad materna en las pacientes atendidas de 2011 a 2012. Métodos: se analizaron los datos de las pacientes en admisión hospitalaria, el diagnóstico y la severidad de la enfermedad, la presencia de comorbilidad y las complicaciones que ocurrieron durante el tratamiento y las causas de muerte de pacientes embarazadas o puérperas. Resultados: fueron atendidas 137 pacientes de las cuales 87 (63.5 %) requirieron ser hospitalizadas, 36 (41.3 %) presentaron criterios para complicación materna severa (CMS); la mayor parte de pacientes con CMS se encontraban en el puerperio postcesárea, Once pacientes fallecieron, cinco se consideraron muertes maternas indirectas y 6 muertes tardías. Conclusiones: las CMS y las muertes fueron más frecuentes en el puerperio. Las causas indirectas fueron las más frecuentes.

    Friedrich Wilhelm Tönnies' name is hardly found in the major histories of astronomy. This is not surprising since he died before the age of twenty-one. Nevertheless, and perhaps because he knew at heart that not much time was granted to him, he left an astonishingly prolific oeuvre which indicates his rich talents. His contemporaries also testify that this son af a wealthy textile merchant had a great talent. But it is idle to speculate whether he would have become a second Bessel, or just an inconspicuous high school teacher in some remote Prussian province. He experienced a decisive career advancement by the Berlin astronomer J.E. Bode, obtained his Ph.D. already at the age of nineteen, published, among other things, about the large solar eclipse of November 19, 1816, and corresponded with several professional astronomers, before he succumbed to a pulmonary disease.

    The use of the telescope for astronomical observations since 1609 was one of the milestones in the celestial research. The contributions in this volume present new insights into the invention of the telescope and its relations to reading stones and spectacles, present investigations of special telescope types of early manufacturers, and analyze the telescopes of some historical observatories and the investigations carried out with them. Other contributions deal with the pictorial appearance of telescopes in baroque art, the connection of telescopes with photography, as well as the development of reflectors in the 20th century. The volume is dedicated to Rolf Riekher, an internationally established specialist ior the history of the telescope, on the occasion of his 85th birthday.

    2011-01-01

    Background In Brazil, despite the growing use of SF-36 in different research environments, most of the psychometric evaluation of the translated questionnaire was from studies with samples of patients. The purpose of this paper is to examine if the Brazilian version of SF-36 satisfies scaling assumptions, reliability and validity required for valid interpretation of the SF-36 summated ratings scales in the general population. Methods 12,423 individuals and their spouses living in 8,048 households were selected from a stratified sample of all permanent households along the country to be interviewed using the Brazilian SF-36 (version 2). Psychometric tests were performed to evaluate the scaling assumptions based on IQOLA methodology. Results Data quality was satisfactory with questionnaire completion rate of 100%. The ordering of the item means within scales clustered as hypothesized. All item-scale correlations exceeded the suggested criteria for reliability with success rate of 100% and low floor and ceiling effects. All scales reached the criteria for group comparison and factor analysis identified two principal components that jointly accounted for 67.5% of the total variance. Role emotional and vitality were strongly correlated with physical and mental components, respectively, while social functioning was moderately correlated with both components. Role physical and mental health scales were, respectively, the most valid measures of the physical and mental health component. In the comparisons between groups that differed by the presence or absence of depression, subjects who reported having the disease had lower mean scores in all scales and mental health scale discriminated best between the two groups. Among those healthy and with one, two or three and more chronic illness, the average scores were inverted related to the number of diseases. Body pain, general health and vitality were the most discriminating scales between healthy and diseased groups. Higher scores were associated with individuals of male sex, age below 40 years old and high schooling. Conclusions The Brazilian version of SF-36 performed well and the findings suggested that it is a reliable and valid measure of health related quality of life among the general population as well as a promising measure for research on health inequalities in Brazil.

    NASA Astrophysics Data System (ADS)

    Lödel, Wolfgang

    The astronomers' desire to penetrate deeper into space transforms into a demand for larger telescopes. The primary mirror constitutes the main part of a reflecting telescope, and it determines all subsequent activities. Already in the 1930s activities existed in the Schott company to manufacture mirror blanks up to diameters of 2 metres, which could not be pursued because of political constraints. This ambitious goal was again picked up a few years after the war. At a time when the procurement of raw materials was extremely difficult, the glass workers of Schott in Jena attacked this large project. After some failures, a good mirror blank could be delivered to the Carl Zeiss Company in 1951 for further processing and for the construction of the first 2-metre reflecting telescope. From 1960 to 1986, this mirror made from optical glass ZK7 served its purpose at the Karl Schwarzschild Observatory in Tautenburg. lt was then replaced by a zero expansion glass ceramics mirror.

Its author was the lawyer, writer and literary theoretican Georg Philipp Harsdouml;rffer (1607-1658), who is primarily remembered as the inventor of the “Nuremberg funnel”. It is possible that a second card game was issued in the same year, but the sources are ambiguous. After some preliminaries on the history of card games, Harsdörffer's pack of cards is presented. In addition, general remarks about the history of sky maps are given.

    Cysticercosis is the most frequent parasitosis of the nervous system and nowadays it is widespread through the world. Despite the development of anticysticercal drugs (praziquantel and albendazole), their efficacy is more marked in cases with parenchymal active cysts and they do not prevent complications such as hydrocephalus. Thus, many patients with neurocysticercosis require surgical intervention, generally of palliative nature, but that may occasionally produce a cure. The clinical outcome of 180 patients with cerebral cysticercosis who underwent surgical treatment form 1970 to 1993 was analyzed. Surgical treatment was performed to control increased ICP in 177 patients and due to local compression of cranial nerves or brainstem in five. Some patients had more than one surgical procedure, totalizing 287 interventions. Increased intracranial pressure (ICP) was caused by hydrocephalus in 91%, by intracranial mass lesion (tumoral form) in 6.2% and by pseudotumor cerebri (pseudotumoral form) in 2.8% of the case. Based on the pathophysiological mechanisms of intracranial hypertension identified through conventional CT-scan, ventriculography, cysternotomography, ventriculotomography and MRI, different surgical approaches were indicated. Patients with tumoral form were submitted to direct approach and cyst removal and generally they had benefits from this procedure. Patients with pseudotumoral form whose clinical treatment failure underwent decompressive craniectomies and had a poor outcome (40% of good results). Direct removal of ventricular/cisternal cysts and/or ventriculoatrial/peritoneal shunting (VA/VPS) was performed in patients with hydrocephalus. Removal of free ventricular cysts in patients who had no ependimitis/arachnoiditis generally allowed a good outcome. Patients with adherent cysts and inflammatory process needed a VA/VPS posteriorly and the outcome was not so good. One hundred thirty-two patients were submitted to VA/VPS (109 as the first procedure and 23 after another surgical treatment). The VA/VPS was effective to control increased ICP, despite many complications observed mainly during the two first postoperative years. After this period the surviving patients generally had a better outcome. The patients submitted to cyst removal due to local compression of cranial nerves/brainstem generally had good results. Based on the experience acquired with the management of these patients we present our recent policy for the treatment of patients with neurocisticercosis.

    The District Authority (Regierungspräsidium) Freiburg interpreted reflective seismic data for the region of Hartheim south of the Kaiserstuhl (Upper Rhine Graben). The seismic data were used to determine the position of the inner fault zone of the Upper Rhine Graben in this area, combined with parameters of depth and thickness for the most important hydrogeothermal reservoirs of the Hauptrogenstein (Middle Jura), Oberer Muschelkalk and Buntsandstein. The inner fault zone shows an offset of up to 3 000 m, that separates the deep subsided inner zone of the Upper Rhine Graben (basin of Hartheim) in the west from the shallower parts in the east (Tuniberg, Freiburger Bucht). In the subsided inner zone of the Upper Rhine Graben temperatures of 130 °C at a depth of 3 000 m or 150 °C in a depth of 3 500 m can be expected. Estimated hydraulic conductivities for the aquifers of the Hauptrogenstein and Oberer Muschelkalk average at T/ H=2ṡ10-6 m2/s with significant standard deviations. The Buntsandstein delivered only a few values. The deep seated waters in the inner zone of the Upper Rhine Graben are dominated by natrium and chloride, showing total dissolved solids (TDS) of several 10s g/l. Waters with the highest value for TDS can be found in the Hauptrogenstein aquifer.

    A existência de observadores é um fato. Este fato, entretanto, permite que possam ser extraídas informações físicas, astrofísicas e cosmológicas. A realidade da existência de observadores foi elevada por Carter [1] ao nível de um princípio, chamado Princípio Antrópico. Em linhas gerais o Princípio Antrópico afirma que a existência de observadores só é possível dentro de certos parâmetros físicos muito restritos. O Princípio Antrópico é uma fonte de compreensão de fatos observáveis do Universo. Na ausência de explicações provenientes das leis da física, as previsões antrópicas tornam-se importantes fatores de esclarecimento. Além disso, o Princípio Antrópico pode ainda atuar como supressor da necessidade de novas teorias. Foi aliás no quadro de discussões em torno da necessidade de novas teorias que o Princípio Antrópico foi concebido, nomeadamente na discussão em torno dos números muito grandes. Para explicar estes grandes números, Dirac [2] formulou uma hipótese inovadora, a de que a constante gravitacional variaria com o tempo na forma 1 - µ G t . Se aceita, tal relação se constituiria numa revisão das leis da física já estabelecida. Daria origem a uma nova física. Entretanto, com a elaboração do Princípio Antrópico por Dicke [3] e Carter [1] a coincidência de tais grandes números foi compreendida dentro da física tradicional, sem a necessidade de recurso a novas leis.

    Introdução: A psiquiatria é influenciada pelas mudanças que ocorrem na sociedade, devendo estar em constante renovação, antevendo futuros comportamentos e doenças. Este estudo pretende descrever a opinião dos internos de psiquiatria em Portugal relativamente ao seu internato e às modificações que nele gostariam de assistir no futuro próximo.Material e Métodos: Um questionário estruturado de 26 perguntas foi desenvolvido pela Associação Portuguesa de Internos de Psiquiatria e enviado por email.Resultados: A percentagem de respostas obtidas foi de 41,5%. A maioria dos internos estava satisfeita com a sua formação. Contudo, algumas mudanças foram sugeridas no que diz respeitos aos estágios obrigatórios e opcionais. A maior parte dos internos requer que as psicoterapias sejam incluídas no âmbito do internato, solicitando também um acesso mais fácil à investigação e a oportunidades de estágio no estrangeiro.Discussão e Conclusão: Esta perspectiva detalhada pode facilitar a transformação dos currículos do internato em Portugal e naEuropa, permitindo a melhoria do internato de psiquiatria, bem como dos cuidados de saúde mental.

    Este artigo apresenta os principais eventos ocorridos na história do ensino de astronomia nos cursos superiores que existiram no Brasil desde a chegada da Família Real portuguesa em 1808 até o final do período monárquico. Para compor esse esboço histórico, utilizamos, principalmente, livros didáticos, regulamentos, decretos e leis responsáveis pelas organizações dos conteúdos oferecidos e das carreiras dos responsáveis pela disciplina. Na análise do material empregado, investigamos a presença de concepções filosóficas e científicas, que podem ter norteado os conteúdos disciplinares. Não realizamos nenhuma comparação com o ensino de astronomia em outros países. Concluímos mostrando que o estudo de astronomia, durante o período monárquico, foi mais direcionado para a formação d engenheiros do que astrônomos. Gostaríamos de observar que o presente artigo não tem a pretensão de abordar o assunto de maneira completa e detalhada.

    Introdução: Os mecanismos imunológicos e inflamatórios têm um papel crucial no desenvolvimento da aterosclerose e na sua tradução clínica. São inúmeros os estudos que procuraram relacionar os mais diversos marcadores inflamatórios – leucócitos, proteína C reactiva, interleucinas, quimiocinas, moléculas de adesão, metaloproteinases, etc – com os factores de risco clássicos da aterosclerose, a formação da placa e os fenómenos clínicos. Não são tantos, que tenhamos conhecimento, os trabalhos que analisaram o comportamento das diversas células mononucleares na fisiopatologia da aterosclerose. Sendo os monócitos/macrófagos e os linfócitos células fundamentais no desencadear e posterior evolução desta doença vascular, procurámos determinar as percentagens das diversas populações celulares periféricas em indivíduos dislipidémicos e em normolipidémicos.Material e Métodos: Por citometria de fluxo, determinámos em indivíduos com dislipidemia e num grupo controlo, as concentrações no sangue periférico dos CD3+, CD4+, CD8+, CD19+, CD56+, CD56CD8+, DN, CD25+, CD26+, CD25CD3+, CD26CD3+, CD25CD26CD3+, CCR5+, CCR5CD3+, CCR5CD4+, HLADR+, HLADRCD4+, HLADRCD8h+, HLADRCD8low+, HLADRCD8+, CD95+, CD95CD95L+, CD3CD95+, CD3CD95L+, CD62L+, CD3CD62L+, CD69+, CD69CD3+ e CD69CD4+. Resultados: Embora na sua grande maioria não tenham sido encontradas diferenças significativas entre os dois grupos de participantes, verificaram-se em algumas populações celulares, resultados que nos mereceram alguns comentários. Neste artigo debruçámo-nos apenas sobre as populações positivas para os CD4, CD8 e CD19.Discussão: A menor concentração das células CD4+ na nossa população de dislipidémicos foi aparentemente inesperada devido ao relacionamento existente entre este tipo celular, os factores de risco e a aterosclerose. Não foram determinados os subtipos Th1 e Th2, nem a população de células reguladoras CD4+CD25+, que poderiam explicar a

    Introdução: As normas de orientação clínica são instrumentos de apoio à decisão que visam a melhoria da qualidade, promovendo as boas práticas clínicas. Os cuidados orientados para o utente permitem uma melhor satisfação e autogestão da saúde, com ganhos de qualidade e potencialmente menores custos.Objetivo: Avaliar o grau de integração dos valores dos doentes nas normas de orientação clínica publicadas em Portugal. Material e Métodos: Reviram-se as 18 normas de orientação clínica da área cardiovascular publicadas em Portugal entre 2011 e 2013, procurando avaliar a introdução das ideias, medos, expectativas e preferências dos doentes. Resultados: Oito normas de orientação clínica estavam relacionadas com processos de diagnóstico e 10 com aspetos de terapêutica. Em cinco normas de orientação clínica (28%) foram encontradas referências a valores dos doentes, todas na área da terapêutica, não existindo nenhuma nas normas de orientação clínica relacionadas com o diagnóstico. A incorporação das expectativas dos doentes foi o aspeto mais presente. Em 78% existiam referências à valorização dos custos financeiros. Discussão: As normas de orientação clínica constituem-se como uma tecnologia de saúde ao dispor dos profissionais com o objetivo de melhorar a prestação dos cuidados assistenciais aos cidadãos, utilizadores últimos destes instrumentos. Como noutros países, há uma tendência a não considerar os utentes e os seus sistemas de valores na estrutura das orientações, privilegiando-se uma lógica populacional nem sempre aplicável ao caso concreto, e uma aritmética financeira pouco suportada em avaliações de custoefetividade. No caso português, a forma como foram propostas foi também condicionadora de desconfiança tanto nos profissionais como nos utentes.Conclusão: As normas de orientação clínica em Portugal apresentam uma baixa taxa de incorporação dos valores dos utentes, de uma forma mais vis

    Introdução: A doença de Pompe ou glicogenose tipo II é uma doença autossómica recessiva por deficiência de maltase ácida. É uma entidade rara, com prevalência de 1/40.000 nas populações holandesa e afro-americana e 1/46000 na população australiana. Embora se distingam três formas de apresentação (infantil, juvenil e do adulto), observa-se um amplo espectro clínico. Em Portugal está disponível terapêutica enzimática de substituição desde 2006.Material e Métodos: Fez-se o estudo retrospetivo de quatro doentes (duas das quais irmãs), baseado na revisão dos processos clínicos.Resultados: Em todas, a doença manifestou-se no segundo ano de vida. O tempo até ao diagnóstico variou entre dois e onze anos. Aquando do diagnóstico, todas apresentavam miopatia com atraso de aquisições motoras e em duas havia hipertrofia miocárdica. A suspeita clínica surgiu por insuficiência respiratória em contexto infeccioso em duas doentes. Em todas havia elevação da creatina quinase e das aminotransferases. Todas evoluíram com insuficiência respiratória crónica por síndrome restritiva. O diagnóstico foi baseado na diminuição da atividade da maltase ácida em fibroblastos (0 a 1,5% do limite inferior do normal). Na biópsia muscular, realizada em três doentes, demonstrou-se acumulação lisossómica de glicogénio. Todas apresentavam a mutação c.1064T > C no exão 6 do gene GAA (glucosidase-alpha-acid), em homozigotia numa delas, associada às mutações c.1666A > G no exão 12 e c.2065G > A no exão 15 nas duas irmãs e à mutação c.380G > T no exão 2 na doente mais nova. Todas iniciaram terapia enzimática de substituiçãologo que disponível, com boa tolerância. A doente mais jovem faleceu pouco depois. As outras mantêm medidas de suporteventilatório e fisioterapia, deslocando-se a mais velha, em cadeira de rodas, mantendo a irmã marcha independente e necessitando a mais nova de andarilho.Conclusão: Os nossos casos incluem

  19. Simplificando a luneta com lente de óculos

    NASA Astrophysics Data System (ADS)

    Canalle, J. B. G.; de Souza, A. C. F.

    2003-08-01

    A principal ferramenta de trabalho do astrônomo é o telescópio. O manuseio do mesmo é sempre motivo de enorme curiosidade por parte de alunos do ensino fundamental ou médio e até mesmo dos respectivos professores. Visando propiciar o acesso de alunos e professores ou interessados em geral a uma luneta de fácil construção, com materiais alternativos, de fácil localização no comércio, de baixo custo, resistente ao manuseio de alunos, simplificamos a montagem de uma luneta construída com lente de óculos, de 1 ou 2 graus positivos, e monóculo de fotografia, publicado por este autor no CCEF, vol.11(3), 212, 1994. Esta luneta, a qual permite ver as crateras lunares, apresentava como maior dificuldade de construção o tripé e o local de formação da imagem. Substituímos o tripé de madeira por uma simples garrafa PET de 2 litros cheia d'água. No lugar da ocular usamos a lente do monóculo de fotografia (ou visor de fotografia) encaixado dentro de uma bucha de redução curta, de 40 x 32 mm, e esta não mais dentro de uma luva (conexão hidráulica) de 40 mm de diâmetro, mas sim encostada no próprio tubo de PVC móvel (o qual permite o ajuste do foco) de 40 mm de diâmetro e presa a este por outro tubo de 40 mm de diâmetro e 10 cm de comprimento, serrado ao longo do seu comprimento. Com isto podemos ajustar a posição deste tubo de 10 cm também para que uma das suas extremidades coincida com o local de formação da imagem. Desta forma o observador saberá o local exato da formação da imagem, o que não era evidente na montagem anterior e causava uma dificuldade inicial até se descobrir a posição exata em que se deveria colocar o olho. Deste maneira, a montagem inicial que já era simples ficou ainda mais simples, mais barata e mais confortável para o uso. Um exemplar da mesma será exposto durante a XXIX Reunião Anual da Sociedade Astronômica Brasileira para inspeção e uso dos participantes.

  18. Ondas de choque em jatos de quasares e objetos BL Lacertae

    NASA Astrophysics Data System (ADS)

    Melo, F. E.; Botti, L. C. L.

    2003-08-01

    Este trabalho é parte de um projeto que vem sendo realizado há dois anos no CRAAM, cujos objetivos principais são analisar e aplicar um modelo generalizado de ondas de choque em jatos relativísticos de plasma, presentes em quasares e objetos BL Lacertae, para explicar a variabilidade observada nestes objetos. O método consiste em uma decomposição de curvas de luz em séries de explosões similares, em várias freqüências, baseando-se em uma evolução espectro-temporal média das explosões. A partir da evolução média, um ajuste de cada explosão é feito com base em equações empíricas, modificando-se apenas parâmetros específicos de cada explosão. Inicialmente o modelo foi aplicado ajustando-se as curvas de luz a explosões delineadas por uma evolução do choque em três estágios, segundo a predominância do processo de emissão: síncrotron, Compton e adiabático. Entretanto, nesta nova fase de projeto, visando uma parametrização mais concisa, uma otimização do algoritmo de ajuste e uma convergência mais rápida, a formulação para cada evento foi assumida com uma evolução em apenas dois estágios: subida e descida. Isto possibilitou uma ótima delineação das curvas de luz das fontes OV236, OJ287, 3C273 e BL Lac, entre 1980 e 2000, nas freqüências 4.8, 8.0, 14.5 e 22 GHz, utilizando-se dados do Observatório da Universidade de Michigan, do Observatório do Itapetinga (Atibaia SP) e do Observatório Metsähovi. Como conclusões importantes, verificou-se que: os parâmetros ajustados descrevem o comportamento do jato; os valores do índice que descreve a expansão do jato sugerem que o mesmo se expande de uma forma não-cônica; o campo magnético é turbulento atrás da frente de choque; e as peculiaridades das explosões são devidas à influência de grandezas tais como o coeficiente da distribuição espectral de energia dos elétrons, a intensidade de campo magnético e o fator de feixe Doppler, no início do choque.

    Objetivo Realizar uma análise da inserção da ética e humanidades no currículo do Curso de Medicina da Escola Superior em Ciências da Saúde - ESCS, escola pública do Distrito Federal, Brasil, de forma a contribuir com o processo de gestão curricular. Metodologia O Estudo é de coorte e documental. Foram pesquisados 37 termos relacionados à ética e 36 referentes à humanização nos objetivos educacionais e conteúdo dos módulos temáticos, habilidades e atitudes e interação ensino-serviço-comunidade, de 1a a 4a série e no programa do internato no currículo (ano 2006) e no projeto pedagógico do Curso de Medicina (2001). Resultados Maior inserção da humanização, ética e bioética na 1a e 2a série, quando comparado à inserção na 3a e 4a série e no internato, (IC95%-α=0,034, pvalue=0,007). Unidade de habilidades e atitudes: freqüência das 3 temáticas no currículo da 1a a 4a séries (IC95%-α=0,026, pvalue=0,013). Quando comparada a inserção entre o internato e as quatro primeiras séries, observa-se que nestas a inserção da temática humanização é superior (IC95%-α=0,042, pvalue=0,029). Conclusão O currículo desenvolvido no ano de 2006 na ESCS apresentou correlação com o projeto pedagógico do curso e contemplou a temática de forma abrangente, em todas as séries e internato.

  20. Espectroscopia infravermelha de núcleos ativos de galáxias: resultados adicionais

    NASA Astrophysics Data System (ADS)

    Rodríguez Ardila, A.; Viegas, S.; Pastoria, M. G.

    2003-08-01

    Apresentamos resultados parciais de um levantamento espectroscópico na região do infravermelho próximo (NIR) realizado em 30 núcleos ativos de galáxias (AGN), incluindo vários objetos selecionados do catálogo PG com z de até 0.55. O objetivo é estudar a natureza do contínuo observado e as condições físicas do gas emissor. Todas as fontes de tipo 1 apresentam uma mudança na inclinação do contínuo na região de 1.2mm, associada ao término da contribuição do contínuo emitido pelo AGN e ao início da contribuição do contínuo emitido pela poeira quente atribuída ao tórus que rodeia a fonte central. O índice espectral associado à segunda contribuição varia apreciavelmente de objeto para objeto. Este resultado é comparado com distribuições espectrais de energia preditas por modelos de toroides para testar a validez do modelo unificado. A partir das linhas de FeII observado nos espectros deriva-se, pela primeira vez nessa região espectral, um template empírico de FeII para estudar a intensidade e a origem dessa emissão. A intensidade do FeII é estudada em conjunto com aquela da região visível e comparada às predições de modelos teóricos que incluem fluorescência de Lya, excitação colisional e auto-fluorescência como mecanismos dominantes de exitação. Encontra-se que os dois primeiros processos dominam na formação do espectro de FeII observado. Indicadores de avermelhamento, entre eles Brg/Pab, Pab/Pag, Pab/Pad e [FeII] 1.257/1.644 mm são utilizados para mapear a distribuição de poeira nas regiões emissoras de linhas. Encontra-se valores de extinção Av~3 associados ao último indicador e valores significativamente menores (Av~1.5) para os restantes, o que sugere que o [FeII] se forma em uma região separada da maior parte do gás emissor de linhas estreitas.

    PubMed

    Santana, Isabel; Duro, Diana; Lemos, Raquel; Costa, Vanessa; Pereira, Miguel; Simões, Mário R; Freitas, Sandra

    2016-04-01

    Introdução: O Mini-Mental State Examination é o teste de rastreio de défice cognitivo/demência mais difundido. No nosso país têm-se utilizado pontuações de corte definidas por grupos de literacia, mas existem novas propostas sustentadas por estudos mais representativos. Propomo-nos confirmar a influência da idade e da escolaridade no desempenho, avaliar a capacidade discriminativa dos novos dados normativos e testar a acuidade diagnóstica das pontuações de corte validadas para o défice cognitivo ligeiro e para as formas mais prevalentes de demência. Material e Métodos: O estudo incluiu 1 441 participantes escolarizados, divididos em sete subgrupos: Défice cognitivo ligeiro, doença de Alzheimer, demência fronto-temporal, demência vascular, demência com corpos de Lewy, controlo-comunidade e controlo-clínica- memória. Resultados: Em conjunto, idade e escolaridade explicam 10,4% da variância dos resultados no Mini-Mental State Examination, com ambas contribuindo significativamente para a predição dos resultados. A acuidade diagnóstica com base nos dados normativos mais recentes foi sempre superior à conseguida com as pontuações de corte de validação, revelando uma especificidade excelente (superior a 90%) e uma sensibilidade também excelente para a doença de Alzheimer ligeira (91%), boa para demência com corpos de Lewy (78%), baixa para o défice cognitivo ligeiro (65%) e demência fronto-temporal e demência vascular (55%). Discussão e Conclusões: O desempenho no Mini-Mental State Examination é influenciado pela idade e pela escolaridade, apoiando a utilização de dados normativos que considerem estas variáveis. Com esta abordagem, o Mini-Mental State Examination poderá ser um instrumento sensível e específico para o rastreio da doença de Alzheimer em todos os níveis de cuidados de saúde, mas a acuidade de diagnóstico é limitada noutras situações frequentes em consultas especializadas, como o défice cognitivo ligeiro

    Introdução: A infeção por Campylobacter é a principal causa de gastroenterite aguda bacteriana pediátrica na União Europeia.Objetivos: Conhecer a prevalência de isolamento deste agente nas crianças admitidas na urgência com gastroenterite aguda que realizaram coprocultura, caracterizando a microbiologia, epidemiologia, clínica, terapêutica e complicações associadas.Material e Métodos: Casuística por consulta dos processos dos doentes admitidos na Urgência Pediátrica dum hospital distrital, durante 30 meses, com o diagnóstico de gastroenterite aguda e isolamento em coprocultura de Campylobacter.Resultados: Das 216 coproculturas efetuadas, 98 (45%) foram positivas. Identificámos Campylobacter spp. em 49 (50%) doentes. Destes, 30 (61%) eram do género feminino. A mediana de idades foi 23 meses. Catorze doentes tinham idade inferior a um ano, 25 entre um e cinco anos e 10 idade superior a cinco anos. Verificámos diarreia aquosa em cinco (10%) doentes, diarreia com sangue em 44 (90%), sangue e muco em 14 (29%), febre em 23 (47%), dor abdominal em 14 (29%) e vómitos em 11 (22%). Registámos um caso de sépsis. Internámos cinco doentes. Oito doentes foram medicados com azitromicina.Discussão: Esta é a maior casuística nacional publicada de gastroenterite aguda a Campylobacter em idade pediátrica e a primeira no sul do país. Campylobacter foi a principal bactéria identificada, associada maioritariamente a doença auto-limitada. Contudo, há a considerar formas de infeção graves. O aumento da resistência às quinolonas é preocupante.Conclusão: A utilização criteriosa da coprocultura permite a identificação etiológica na gastrenterite aguda bacteriana. O crescente aumento dos casos de Campylobacter diagnosticados reforça a necessidade de maior controlo das medidas de higiene na manipulação dos alimentos.

    A Rede Neural Artificial (RNA), no âmbito da teoria computacional, constitui uma teoria emergente que, por possuir habilidade em aprender a partir de dados de entrada, encontra diferentes aplicações em diferentes áreas. Um exemplo é a utilização de RNA na caracterização de padrões associados à dinâmica de processos espaço-temporais relacionados a fenômenos físicos não-lineares. Para obter informações sobre o comportamento destes fenômenos físicos utiliza-se, em diversos casos, seqüências de imagens digitalizadas, onde a caracterização de alguns fenômenos espaço-temporais é o procedimento mais viável para descrever a dinâmica das regiões ativas do Sol. Com base em imagens observadas por telescópios a bordo de satélites, estudos de previsão de eventos solares podem ser programados, permitindo prever possíveis efeitos posteriores nas regiões mais próximas da Terra (tempestades geomagnéticas e irregularidades ionosféricas). Neste trabalho avaliamos o desempenho da RNA para estimar padrões espaço-temporais, ou seja, imagens solares em ultravioleta, obtidas através do telescópio a bordo do satélite SOHO. Os resultados mostraram que as RNA conseguem generalizar os padrões de maneira satisfatória sem perder de forma significativa os principais aspectos da configuração global da atmosfera solar, comprovando a eficácia da RNA como ferramenta para esse tipo de aplicação. Portanto, este trabalho comprova a viabilidade de uso desta ferramenta em projetos voltados ao estudo do comportamento solar, em trabalhos do grupo de Física do Meio Interplanetário (FMI) na DAS e em programas desenvolvidos pelo Núcleo de Simulação e Análise de Sistemas Complexos (NUSASC) do Laboratório Associado de Computação e Matemática Aplicada (LAC) do INPE.

    2003-08-01

    O principal objetivo deste trabalho é auxiliar o professor de Geografia em sala de aula no ensino de tópicos relacionados com a Cosmologia. A idéia deste trabalho surgiu quando foi constatado que o professor de Geografia tem dificuldades de ensinar este tópico. Esta constatação foi feita por uma das autoras ao lecionar este tópico no ensino fundamental e em discussões com outros professores de Geografia. Da mesma maneira que ocorria desde os tempos mais antigos, os alunos têm muito interesse em conhecer os fenômenos que ocorrem no Cosmo, porém os livros didáticos de Geografia utilizados em sala de aula não são ricos em informações sobre este assunto. Assim, o professor de Geografia tem poucas informações para discutir este assunto em sala de aula e não dá a devida importância para este tópico. Então, foi desenvolvido um material de apoio para professores de Geografia sobre a origem do Universo, sua evolução e seu possível futuro evolutivo segundo as mais recentes teorias, com base em perguntas feitas pelos alunos de ensino fundamental e as informações trazidas nos livros didáticos Não cabe a este material inovar e tão pouco trazer uma metodologia de ensino de Cosmologia. Neste material o professor de Geografia pode encontrará um banco de informações, que constitui no estabelecimento de conceitos, teorias e hipóteses, sobre a Cosmologia, em linguagem simples e de fácil entendimento. Para desenvolvê-lo, foram feitas pesquisas não exaustivas em livros e revistas científicas, compilação e discussão em forma cronológica das teorias aceitas sobre modelos cosmológicos. Portanto, este material será apresentado neste trabalho.

    Abstract Background At least 511 species of birds occur in the semiarid region of northeastern Brazil and many of them interact with human populations in a number of different ways, including their use in zootherapeutics and their links with local beliefs. Objective The present work examined these types of birds/human interactions (use in zootherapeutics and their links with local beliefs) in the semiarid region of Rio Grande do Norte State in northeastern Brazil. Methods Information was obtained through semi-structured interviews with 120 local residents. Results A total of 16 wild bird species distributed among 11 families were found to interact directly with humans, with Columbidae being the best represented family. Seven species were identified in the medicinal category, five were related to symbolic aspects, while four species were identified as being related to both categories (medicinal and symbolic). Conclusion The accumulated folk knowledge, beliefs, and practices involving the avifauna in the semiarid region of Brazil, whether symbolic or medicinal, demonstrated the cultural importance of this vertebrate group to local human populations and revealed a belief system intrinsically related to cynegetic practices in the region.

    Sendo a Astronomia uma das cièncias mais antigas da humanidade, e considerando sua importáncia histórica e cultural, é de extrema releváncia que tópicos relacionados a ela sejam tratados nas escolas. Embora os Parámetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as Orientaçiacute;es Complementares aos Parámetros (PCN+) apontem a importáncia de uma abordagem significativa de conceitos relacionados à Astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano e sejam alvos da curiosidade natural dos jovens. Da observação dessa curiosidade em alunos de uma escola pública paulista, na cidade de Suzano, surgiu o interesse em investigar os conhecimentos básicos em Astronomia dos alunos do Ensino Médio desta escola, constituindo-se este como principal objetivo desta pesquisa. Para tanto foi elaborado um questionário de múltipla escolha aplicado inicialmente a 34 alunos do primeiro ano e, posteriormente, a mais 310, distribuídos entre as très séries do Ensino Médio dos períodos matutino e noturno. Dessa forma, observou-se que 73,9% dos estudantes identificaram o Sol como sendo uma estrela, 67,1% mostraram compreender a sucessão entre dia e noite e 52,3% relacionaram o Big Bang à origem do Universo. Em contrapartida, apenas 34,5% relacionaram as estaçíes do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influència gravitacional simultánea da Lua e do Sol como responsável pelo fenòmeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distáncia e 34,2% reconheceram as estrelas cadentes como meteoros, evidenciando-se assim o pequeno discernimento dos estudantes quanto aos fenòmenos e termos astronòmicos do cotidiano. Além disso, foram comparadas as respostas de alun! os de diferentes s

    Através de simulações numéricas buscamos quantificar os efeitos que o binarismo não resolvido causa na determinação da função de massa (MF) de aglomerados estelares. Geramos diagramas cor-magnitude (CMDs) artificiais simulando uma população única, caracterizada por estrelas de mesma idade e composição quí mica, com uma fração de binárias não resolvidas e distribuição em massa das estrelas dada por uma MF do tipo lei de potência. A presença de pares de estrelas não resolvidos faz com que a MF obtida da função de luminosidade (LF) tenha a têndencia de ser mais plana do que a MF que gerou o CMD artificial. Propomos um tratamento de correção para tal efeito. Outro efeito relacionado diz respeito ao alargamento do CMD, que apresenta-se como um indicador do número total de estrelas no domí nio de baixas massas (m < 0.6M¤). Todos os resultados acima possuem uma forte dependência com os erros fotométricos e estão baseados na hipótese de que ambas estrelas do par não resolvido são sorteadas de uma mesma MF de forma independente. O objetivo final é aplicarmos o tratamento aqui desenvolvido para implementarmos a análise da nossa amostra de aglomerados ricos da Grande Nuvem de Magalhães.

    A comunidade astronômica brasileira de há muito almeja ter a sua disposição um instrumento científico com o qual possa fazer pesquisa de vanguarda e manter a competitividade científica a nível internacional. Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

    Apresentaremos os resultados de uma investigação espectroscópica cooperativa da estrela magnética HD 190073. As observações foram conduzidas no Observatório do Pico dos Dias (LNA/MCT), European Southern Observatory (ESO, Chile), e Crimean Astrophysical Observatory (CrAO, Ucrânia), entre 1998 e 2002. Discutiremos em detalhe um dos padrões mais marcantes do espectro desse objeto - as multicomponentes em absorção das linhas Ca ii K e H. De acordo com nossos resultados, a estrutura complexa desse perfil permaneceu constante durante várias decadas (dos anos 30 até os anos 80) após o que apresentou mudanças marcantes nos anos 90. Essa variabilidade apresenta óbvia contradição com a interpretação tradicional desse fenômeno como o resultado de espalhamento ressonante atuando seletivamente sobre o vento estelar em distâncias diferentes. Propomos uma explicação alternativa com base em uma topologia especí fica do campo magnético estelar. Essa hipótese permite, também, explicar uma série de outras peculiaridades observadas no envoltório de HD 190073, tais como: (a) a baixa velocidade de rotação pode ser o resultado da interação entre a magnetosfera estelar e um disco equatorial hipotético; (b) o gás circumstelar acumulado em loops magnéticos em latitudes intermediárias pode estimular a formação de regiões gasosas densas a distâncias intermediárias da estrela, onde linhas em emissão com perfil simples são formadas.

    Diacetoxyscirpenol (DAS), a Fusarium mycotoxin belonging to the trichothecene type A mycotoxins, is able to contaminate food and feed worldwide. Only limited information is available regarding the metabolism of DAS. The present study used ultrahigh-performance liquid chromatography-quadrupole/time-of-flight hybrid mass spectrometry (UHPLC-Q/TOF) to investigate the in vitro phase I and II metabolism of DAS by rat, chicken, swine, goat, cow, and human liver microsomes. An extensive metabolization profile of DAS has been observed. A total of seven phase I and three phase II metabolites of DAS were detected. Among the identified molecules, four phase I metabolites (8β-hydroxy-DAS, neosolaniol, 7-hydroxy-DAS, and its epimer) and two phase II metabolites (4-deacetyl-DAS-3-glucuronic acid and 4-deacetyl-DAS-4-glucuronic acid) were identified for the first time. These results indicate that the major metabolic pathways of DAS in vitro were hydrolyzation (M1-M3), hydroxylation (M4-M7), and conjugation (M8-M10). Qualitative differences in phase I and II metabolic profiles of DAS between the five animal species and human were observed. 4-Deacetyl-DAS was the primary metabolite from liver microsomes of all species, especially human. The in vivo metabolism of DAS in rats and chickens after oral administration of DAS was also investigated and compared. The major metabolites for rats and chickens were 4-deacetyl-DAS and 7-hydroxy-DAS. These results will help to gain a more detailed insight into the metabolism and toxicity of DAS among different animal species and human.

    Introdução: O objectivo geral deste artigo consiste em comparar o desempenho do EQ-5D e do SF-6D em quatro grupos de doentes que sofrem de asma, doença pulmonar obstrutiva crónica, cataratas e artrite reumatóide. Em particular, este artigo tem dois objectivos específicos: 1) estudar o nível de concordância entre os índices e os sistemas descritivos das dimensões do SF-6D e EQ-5D, e 2) analisar a capacidade de discriminação dos instrumentos.Material e Métodos: Uma amostra de 643 doentes respondeu ao SF-36v2 e ao EQ-5D. Foram analisados a capacidade de discriminação dos instrumentos, bem como o nível de concordância entre os índices e os sistemas descritivos das dimensões do SF-6D e EQ-5D. O nível de concordância entre os instrumentos foi estudado com base em coeficientes de correlação e nos gráficos de Bland-Altman, enquanto a influência da condição médica e de outras variáveis de natureza sociodemográfica nos índices foi analisada com o recurso a testes não paramétricos. Utilizaram-se também testes para amostras emparelhadas para identificar diferenças entre osscores finais dos instrumentos.Resultados e Discussão: Verificou-se a existência de uma correlação forte e de uma concordância elevada entre os dois índices. Em termos globais, os índices diferem por condição médica e por grupo sociodemográfico e ambos os instrumentos demonstraram uma capacidade discriminativa semelhante entre grupos sociodemográficosConclusão: Confirmou-se a hipótese de que o SF-6D gera valores de utilidade superiores em populações com doenças. O SF-6D e o EQ-5D parecem comportar-se de forma diferente em cada uma das doenças analisadas, uma vez que as medidas descritivas diferem entre instrumentos e os coeficientes de correlação não são uniformes. Os resultados demonstraram que o EQ-5D e o SF-6D geram valores de utilidade diferentes, mas que existe uma concordância elevada entre os dois instrumentos. Pode-se concluir que os resultados

    A nebulosa CRL 618, uma proto-nebulosa planetária cuja nuvem molecular espessa envolve uma estrela B0, contém uma grande quantidade de C2H2 e CH4. Estas moléculas são consideradas os tijolos da criação de grandes moléculas carbonadas como os Hidrocarbonetos Policíclicos Aromáticos (PAHs). Esta nebulosa, por estar exposta a intensos campos de UV e Raios-X, é uma região de fotodissociação molecular que propicia a formação de novas moléculas, confirmada pela presença de C4H2 e C6H6 (Benzeno), que é a unidade básica dos PAHs. Atribui-se a esta família de moléculas orgânicas duas propriedades fundamentais, a resistência para sobreviver ao campo de radiação UV interestelar e a geração das bandas de emissão não identificadas (UIR) observadas no infravermelho. No entanto, alguns autores questionam a resistência dos PAHs ao campo de radiação UV interestelar. Empregando a técnica de Espectrometria de Massas por Tempo de Vôo, no modo de coincidência fotoelétron-fotoíon, estudamos a ionização e fragmentação das seguintes moléculas: Benzeno, Benzeno deuterado, Naftaleno, Antraceno e Fenantreno. Utilizamos uma fonte de Hélio monocromática em 21,21 eV (584,5 Å) e a radiação Síncroton do Laboratório Nacional de Luz Síncroton (LNLS) em diferentes energias nas proximidades da borda do C 1s ( 290 eV). Comprovamos a estabilidade dos PAHs sob ação de UV (21,21 eV), onde eles apresentam um baixo nível de fotodissociação, produzindo fragmentos ionizados com rendimento total na ordem de 5 por cento em relação ao íon molecular pai. Entretanto, em altas energias, na faixa de Raios-X, a quebra destas moléculas torna-se mais intensa, com a produção de muitos fragmentos. Como uma das rotas de fragmentação do Naftaleno é [(C10H8) = > (C6H6+) + (C4H2) + (e-)], e como temos as evidências observacionais da existência do C4H2 e C6H6 na nebulosa CRL 618, sugerimos que este ambiente também possui o Naftaleno.

  15. Coerência espectroscópica de famílias de asteróides

    2003-08-01

    As Famílias de asteróides são caracterizadas como agrupamentos de objetos provenientes da quebra por colisão de corpos precursores. Desta forma, seus membros devem preservar relações genéticas que podem ser traduzidas sob a análise de suas características espectrais. Neste trabalho é apresentado o primeiro estudo espectroscópico de todas as famílias de asteróides do cinturão principal. Para tal, a divisão em famílias foi refeita utilizando-se o método HCM com uma base de elementos próprios analíticos (Knezevic e Milani, Jun 2001) e para o estudo espectroscópico foram utilizadas diversas campanhas de observação espectroscópica, tais o S3OS2 e o SMASSII, bem como outros dados disponíveis na literatura. A homogeneidade espectroscópica de cada família foi avaliada através da verificação das classes espectroscópicas presentes, bem como da comparação destes espectros com os de objetos de fundo, localizados na vizinhança da família. Vinte e duas famílias foram analisadas (as que possuíam mais do que 3 membros com espectro) e, dentre as principais conclusões pode-se citar a homogeneidade espectroscópica e, provavelmente mineralógica das famílias de Vesta, Eunomia, Hoffmeister, Dora, Merxia, Agnia, Koronis e Veritas. Esta última em particular, foi tida como uma família não homogênea espectroscopicamente em trabalho anterior (Di Martino et al. 1997). Outro resultado interessante é, por um lado, a aparente falta de homogeneidade dos membros da família de Eos, e por outro sua forte distinção dos objetos de fundo. O oposto ocorre na família de Themis, esta apresentando-se espectroscopicamente compatível com os objetos de fundo, mas com grande homogeneidade taxonômica entre seus membros. Algumas das famílias apresentam asteróides "intrusos" (objetos cujas características físicas não são compatíveis com aquelas dos membros da família) que, de modo geral desaparecem ao se considerarem níveis mais baixos de corte para a

    NASA Astrophysics Data System (ADS)

    Ferber, Magnus Ulrich

    The example of the late humanistic scholar Max Welser (1558-1614) from Augsburg proves the gain of recognition of astronomy in the scholarly surroundings, which arose through its new results after the invention of the telescope. This explains why an exponent of the humanistic ideal of education worked towards appearing as the patron of a professional astronomical debate, as it was done by Welser, in 1611-1613, in the debate on sunspots between Christoph Scheiner and Galileo Galilei. Nevertheless, the split in the scholarly world between humanists and scientists proved to be so fundamental at that time, that Welser, in order to be accepted also by the mathematici, had to establish anew his renown in these circles independent of his philological achievements. At the same time, he did not undertake anything to integrate the astronomers into the humanistic res publica litteraria.

    The work presents a continuation in the series related to the long-term space observations made by ground-based neutron monitoring stations. The cosmic ray intensity variation is considered as affected by interplanetary magnetic clouds during low-amplitude anisotropic wave train (LAAWT) events. It was observed that the solar wind velocity is higher than normal (> 300 km/s) while the interplanetary magnetic field (IMF) strength is lower than normal on the arrival of magnetic cloud during LAAWT events. The proton density is found to remain significantly low at high solar-wind velocity, which was expected. The north/south component of interplanetary magnetic field turns southward one day before the arrival of cloud and remains in this direction after that. The cosmic ray intensity is found to increase with the solar wind velocity. It is noteworthy that the cosmic ray intensity significantly increases before and 90 h after the arrival of such a cloud, and decreases gradually after its passage. The north/south component of IMF (Bz) is found to significantly correlate with latitude angle (Ө) and disturbance storm time index Dst, whereas the geomagnetic activity index (Ap) significantly anti-correlates with these parameters, decreasing with (Ө) and Dst increasing on the arrival of interplanetary magnetic cloud during LAAWT events. Raksts ir turpinājums darbu sērijai par dažādām parādībām kosmosā, kas balstītas uz novērojumiem un datiem, iegūtiem dažādos laika periodos pasaules neitronu monitoringa stacijās (Deep River, Tokija, Maskava, u.c.). Rakstā apskatītās kosmisko staru intensitātes izmaiņas tiek pamatotas ar starpplanētu magnētisko mākoņu parādīšanos. Tiek parādītas saules vēja, magnētiskā lauka spēka, vētru pertubāciju indeksa un citu parametru atkarība no magnētisko mākoņu parādīšanās. Tiek atzīmēts, ka kosmisko staru intensitāte strauji pieaug pirms mākoņu parādīšanās un 90 stundu laikā pēc tiem, un pakāpeniski samazinās pēc to aiziešanas.

    NASA Astrophysics Data System (ADS)

    Kühn, Ernst

    Since 1937, the latin edition of Johannes Kepler's Astronomia Nova (1609) is available as a standard text. Here, in the 57th chapter, the third one of 48 important marginalia of Kepler, is reproduced as ⪉quo;Quae sit genuina et απολογητοσ mensura librationis huijus etc.». The Grecized word «αpi;ολογητοσ» was ignored to a large extent by translators and commentators, and was at least declared enigmatic by Donahue (1992). A look in the original copies of the 1609 edition shows that it is written ατιολογητοσ, not π but a τι. απολογητοσ in KGW is a read error. In the context of Keplers «natural, causal magnet-like forcesraquo; of planetary motion the conjecture αιτιολογητοσ (as a typographical error a ι is omitted) immediately suggests itself: causally, aetiological. This solution of the απολογητοσ riddle indicates the tight brace between the important Chapter 57 of Kepler's celestial physics and and the complete title ASTRONOMIA NOVA ΑΙΤΙΟΛΟΓΗΤΟΣ, SEV PHYSICA COELESTIS etc.

O globo terrestre paralelo é um antigo dispositivo, muito simples e criativo que, empregado de forma sistemática nas aulas de astronomia, converte-se em uma ferramenta didática de grande potencialidade. Orientado adequadamente de acordo com o meridiano local, esse instrumento permite acompanhar as sombras em qualquer região da Terra que esteja iluminada pelo Sol, além de oferecer uma visualização clara do terminadouro, a linha que divide o dia da noite em nosso planeta. Com o conhecimento das sombras, é possível estimar a latitude de uma localidade e inferir a hora solar local em qualquer lugar do hemisfério iluminado do planeta. Além disso, mediante o emprego do globo terrestre paralelo, pode-se compreender, de maneira simples, que existem regiões onde os objetos às vezes não projetam sombras e outras, pelo contrário, que às vezes se convertem em "países das sombras longas". Neste trabalho, primeiramente, descrevemos o dispositivo, seus fundamentos básicos de construção e funcionamento.

Ein solches Modellsystem ist das chaotische Wasserrad, das Lehrer auf einfache Weise für den Schulunterricht nachbauen können. Im Wesentlichen steuert der Zufluss des Wassers das Verhalten des Wasserrads. Wächst er, so durchläuft das Rad von der geordneten, gleichförmigen Drehung bis zum Chaos verschiedene Phasen von Bewegungsfiguren. Das Experiment kann grundlegende Modelle und Begriffe der Chaostheorie demonstrieren: lokale und globale Bifurkationen und verschiedene Übergänge ins Chaos.

    Introducción: La determinación del gasto energético en reposo (GER) se calcula cotidianamente a partir de fórmulas predictivas aunque el resultado varía dependiendo de la población. Objetivo: Comparar la determinación del GER mediante calorimetría indirecta y mediante las ecuaciones Harris-Benedict (HB), Mifflin (MF), Organización Mundial de la Salud (OMS), «Institute of Medicine» (IOM), Fórmula Rápida (FR) y Valencia (VA) en mujeres con grados de obesidad I a III. Métodos: Mujeres adultas mestizas mexicanas se incluyeron en el estudio y formaron 3 grupos a partir del índice de masa corporal (IMC). Obesidad grado I (IMC 30,0-34,9; n = 42), grado II (IMC 35,0-39,9; n = 38) y grado III (IMC > 40; n = 41). Se determinó el GER mediante calorimetría indirecta y mediante las ecuaciones antes señaladas. ANOVA de Kruskal-Wallis y la prueba de Dunn se emplearon para el análisis estadístico (p < 0,05 se aceptó como diferencia). Resultados: No se observó diferencia estadística entre los valores de las fórmulas HB, OMS y VA respecto a la CI. La concordancia obtenida de dichas fórmulas fue 63%, 67% y 64%, respectivamente, al analizar los datos en un solo grupo de obesidad. Asimismo, las fórmulas IOM, ER y MF mostraron diferencia estadística significativa versus la CI, siendo la concordancia 58%, 53% y 54%, respectivamente. En el grado III de obesidad la concordancia de VA (78%) y FR (71%) fue la mayor obtenida. Discusión: Las fórmulas HB, OMS y VA fueron las mejores para estimar el GER en mujeres mexicanas con IMC>30. En el grado III VA y FR muestran el mejor desempeño.

Métodos: estudio transversal en el que se determinó el GER en 95 sujetos sanos con normopeso mediante calorimetría indirecta y modelos predictivos (se seleccionaron 45 fórmulas desarrolladas en adultos de características similares a la muestra estudiada que incluían peso, talla, sexo y/o composición corporal). La concordancia entre ambos métodos se analizó mediante el Coeficiente de Correlación Intraclase (CCI) y la prueba de Bland-Altman. La significación se alcanzó con p < 0,05. Resultados: la edad media fue de 42 años (rango: 23,0– 63,2). El GER medio estimado por CI en la muestra fue de 1589 (312) kcal/día [1822,3 (224,3) kcal/día en varones y 1379,3 (216,1) kcal/día en mujeres; p < 0,05]. Las fórmulas que mejor se ajustaron a la muestra fueron las de De-Lorenzo, Harris-Benedict, Schofield y, especialmente, Korth. Conclusiones: existen grandes variaciones en la estimación del gasto energético en reposo en función de la ecuación predictiva utilizada. Las fórmulas de De-Lorenzo, Harris-Benedic y Schofield se comportan adecuadamente en la muestra evaluada; sin embargo, la de Korth demostró ser la más apta. Los modelos que incluyen peso y/o talla obtuvieron mejores resultados que los que contienen variables de composición corporal.

    A pot culture study was carried out at Avinashilingam Deemed University, Coimbatore to assess the effect of few organic manures (herbal microfertilizer, humic acid, farm yard manure (FYM), biofertilizer) and NPK on the growth attributes of carrot. Among the parameters observed, the germination percentage was highest in FYM treated pots on 7 DAS (Days After Sowing) and in NPK treated pots on 21, 28 and 30 DAS. The parameters, such as root length, crown length and vigour index, were studied on 30, 60, 90 and 120 DAS. The root length on 60 and 120 DAS was increased by FYM, whereas on 30 and 90 DAS, increase was observed in NPK treated plants. The crown length was increased by NPK on 30 and 120 DAS, micro herbal fertilizer showed an increase of crown length on 60 DAS and by FYM on 90 DAS. Highest vigour was in FYM treated plants on 30 DAS, in herbal micro fertilizer on 60 DAS in NPK treatment on 90 and 120 DAS. PMID:21114148

    continuada de professores. A participação ativa do professor num grupo de pesquisa na universidade o levou à reflexão sobre caminhos didáticos possíveis de serem descritos, analisados e comunicados a outros professores. A construção de uma pedagogia própria, levando em conta os modelos mentais dos alunos sobre temas básicos de Astronomia, e as mudanças promovidas a partir das aulas dadas, trouxeram amplas conseqüências sobre a pedagogia adotada pelo professor. Hoje a prática desse professor incorpora uma nova visão de ciência e formas alternativas de dialogar com os alunos, elementos indispensáveis a um pesquisador em Educação em Ciências.

    A importância deste trabalho deve-se à seleção de objetos ainda não tratados particularmente como uma família e ao emprego de procedimento estatístico robusto que não precisa de pressupostos ou condições de contorno. Contribui, assim, ao melhor entendimento do cenário das Galáxias Aneladas do diagrama de Hubble via classificação e estudo de subclasses. Selecionaram-se 100 galáxias possuidoras de dois anéis do Catalog of Southern Ringed Galaxies compilado por Ronald Buta, de modo a construir uma amostra completa em termos de conhecimento dos semi-eixos dos anéis interno e externo projetados no plano do céu. Visando uma possível classificação destas galáxias aneladas normais em famílias de acordo com as características geométricas dos anéis, empregou-se primeiramente a Análise de Aglomerados (ferramenta de classificação: medições de semelhança em um espaço bidimensional) para explorar a possível existência de famílias. As variáveis analisadas foram: os diâmetros interiores menores d(I) e maiores D(I), os diâmetros exteriores menores d(E) e maiores D(E), e os ângulos de inclinação dos semi-eixos maiores interiores q(I) e exteriores q(E) dos anéis. Como metodologia de discriminação, empregou-se a construção de Árvores de Classificação. As árvores de classificação constituem um método de discriminação alternativo aos modelos clássicos, tais como a Análise Discriminante e a Regressão Logística, onde uma base de dados é dividida em partições (subgrupos) da árvore por ação de um predictor (variável específica). Os pacotes estatísticos utilizados para o processamento da informação foram: SAS versão 8.0 (Statistical Analisys System) e CART versão 3.6.3. Esta análise estatística sugere a existência de três possíveis famílias de galáxias bianeladas, com base apenas na geometria dos anéis. Como forma exploratória inicial deste resultado, a construção de um diagrama BT (magnitude total) versus o

    Asteróides reacumulados (rubble-piles) são corpos formados por um conjunto de fragmentos agregados primariamente pela sua gravidade. A importância do estudo de corpos reacumulados para a compreensão da evolução do Cinturão de Asteróides tem sido bastante evidenciada, não apenas pela constatação de que estes devem corresponder a uma grande parcela da população de asteróides, mas também por recentes estudos da estrutura e evolução colisional deste tipo de asteróide. A evolução rotacional de corpos reacumulados e a formação de famílias têm sido estudadas pelo nosso grupo, com base no modelo de elipsóides interagentes. Este modelo foi desenvolvido recentemente pelo grupo, e baseia-se na integração numérica das equações de movimento para translação e rotação de corpos formados por um conjunto de elipsóides que interagem entre si pela sua gravidade, força de contato e dissipação de energia por atrito. Considerar a rotação de cada fragmento é a principal diferenciação do nosso modelo em relação aos que têm sido desenvolvidos recentemente. Apresentamos aqui os resultados obtidos para a evolução da rotação de populações de corpos reacumulados. Estes foram submetidos a séries de colisões com projéteis de altas velocidades (5Km/s, típicas do Cinturão atual), distribuídos em uma lei de potências de tamanhos. Estes resultados são comparados com os de Harris (1979), um dos poucos trabalhos analíticos existentes para evolução rotacional de asteróides. O principal resultado obtido por Harris foi a distribuição final de velocidades de rotação como uma lei de potências para corpos pequenos, passando de forma bem definida para rotação constante para os grandes. Nas nossas simulações observamos que as distribuições de velocidades de rotação resultantes tendem a leis de potência, com a inclinação evoluindo no decorrer de colisões subsequentes.

    Objetivos: La nutrición enteral exclusiva (NEE) es una de las estrategias terapéuticas empleadas para inducir la remisión en niños con enfermedad de Crohn (EC). Pese a que la NEE se recomienda en las guías de práctica clínica y en los documentos de consenso, la frecuencia real de su empleo en España es desconocida. Métodos: Encuesta compuesta por 70-items (PRESENT: PREScription of Enteral Nutrition in pediaTric Crohn’s disease in Spain) que se distribuyó a través de la lista de distribución de Sociedad Española de Gastroenterología, Hepatología y Nutrición Pediátrica (SEGHNP). Resultados: Se recibieron los datos de 51 unidades de Gastroenterología Pediátrica del territorio español. De los 287 pacientes recién diagnosticados de EC durante los años 2011-12 en esos centros (139 en 2011 y 148 en 20212), 182 (63%) recibieron NEE (58% en 2011 y 68% en 2012). El 26% de los pacientes que recibieron NEE estaban en recaída. Todos los facultativos que respondieron pensaban que la NEE es efectiva para inducir la remisión clínica en los brotes leves-moderados. El 24,5% no emplean la NEE durante las recaídas. Las formulas enterales empleadas más frecuentemente fueron las específicas para EC (70,6%), la vía oral fue la más utilizada, el 60,8% utilizaron saborizantes y el 9,8% de las unidades permitían un porcentaje variable de calorías en forma de otros alimentos durante el periodo de NEE. El 65% emplearon 5-ASA junto con la NEE, el 69% antibióticos y hasta un 95% inmunomoduladores. La duración de la NEE fue de 8 semanas en el 47,1% de los casos, la transición hacia una dieta normal se realizó de forma secuencial. En relación a las barreras y factores limitantes encontrados por los respondedores para instaurar la NEE destacaban la falta de aceptación por el paciente y/o la familia (71%), falta de tiempo o de personal auxiliar (69%) y la dificultad para convencer al paciente o su familia de la idoneidad del tratamiento (43%).

    O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporção que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galáxias, quasares, pulsares além da existência de todos os elementos que preenchem o espaço cósmico, o vácuo, não mais vazio como se pensou em outros tempos. A mídia explora esse campo de forma mística e também científica. A difusão adequada e dentro dos padrões educacionais vigentes, de conceitos astronômicos, se faz necessária, devido sua presença nos conteúdos escolares, centros de ciência e na mídia, de modo geral. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros introduziu conceitos astronômicos desde a pré-escola até o Ensino Médio. Num estudo realizado com 1.032 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um questionário que abordava conheciment os básicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor já fez alguma apresentação a respeito de astronomia. O presente estudo revelou também que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 28,1% através da televisão e 27,4% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio na forma em que os alunos obtiveram seus conhecimentos astronômicos, a mídia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que não fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espaço. Porém, em certos casos, a mídia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam

    Introdução: O burnout é uma síndrome psicológica, caracterizada por elevada exaustão emocional, elevada despersonalização e baixa realização profissional, que conduz à erosão dos valores pessoais, profissionais e de saúde. Este estudo reporta a prevalência do burnout em profissionais de saúde Portugueses. Material e Métodos: Os níveis de burnout foram estimados pelo Maslach Burnout Inventory - Human Services Survey numa escala ordinal de zero (nunca) a seis (sempre) pontos. A amostra foi constituída por 1 262 enfermeiros e 466 médicos com médias de idade de 36,8 anos (DP = 12,2) e 38,7 (DP = 11,0), respetivamente. Os participantes foram provenientes de todos os distritos nacionais (35% Lisboa; 18% Porto; 6% Aveiro, 6% Setúbal, 5% Coimbra; 5% regiões autónomas), com atuação em meio hospitalar (54%), centros de saúde (Unidade de Saúde Familiar - 30%; Unidades de Cuidados de Saúde Primários - 8%) e outras instituições públicas/privadas (8%). Resultados: A análise dos níveis de burnout revelou que ambas as categorias profissionais apresentaram níveis moderados a elevados de burnout (M = 3,0; DP = 1,7) não sendo significativas as diferenças entre as duas profissões. Vila Real (M = 3,8; SD = 1,7) e a Madeira (M = 2,5; DP = 1,5) são as regiões onde os níveis de burnout são mais e menos elevados, respetivamente. Os níveisde burnout não diferiram significativamente entre Hospitais, Unidades de Cuidados de Saúde Personalizados e Unidades de Saúde Familiares. Os profissionais com maior tempo na função são menos acometidos por burnout (r = -0,15) não ocorrendo associação significativa com a duração da jornada de trabalho (r = 0,04). A má qualidade das condições de trabalho foi o melhor preditor do burnout (r = -0,35). Discussão: A ocorrência da síndrome de burnout em profissionais de saúde portugueses é frequente, estando associada à percepção de más condições de trabalho e à menor duração do tempo de servi

    Introdução: Todos os medicamentos de uso humano são comercializados com um folheto informativo. Estes documentos devem ter uma lista inicial com a identificação de todas as secções, de acordo com o modelo europeu Quality Review of Documents e não serem muito extensos, i.e. com cerca de 1500 palavras. Apenas excepcionalmente são autorizados folhetos relativos a mais de uma dose e/ ou forma farmacêutica (folhetos mistos). Neste contexto, os objectivos incluem a identificação de problemas nos folhetos informativos de todos os medicamentos não genéricos portugueses quanto à presença da lista inicial, à frequência de folhetos mistos e ao número de páginas. Material e Métodos: Consulta dos folhetos na base pública Infomed de acordo com a classificação do Prontuário Terapêutico – 10 (1º trimestre 2012). Os dados recolhidos foram sujeitos a controlo de qualidade e tratamento estatístico. Resultados: Identificação de 2729 folhetos em 3080 especialidades farmacêuticas. Foram avaliados 2042 folhetos (687 não estavam disponíveis), em que 181 (8,9%) não apresentaram lista inicial e 351 (17,2%) eram mistos. O número médio de páginas foi 6,9 (DP = 2,6), o mínimo = 2 e o máximo = 26. Discussão: A leitura e compreensão adequadas dos folhetos portugueses em alguns casos podem estar comprometidas, dado que 1) alguns dos folhetos analisados não continham a lista inicial necessária à adequada localização das informações, 2) foram detetados folhetos mistos e/ou 3) foram encontrados folhetos com uma extensão acima do desejável. Conclusão: Os resultados deste estudo devem informar o processo de desenvolvimento e aprovação dos folhetos pelos titulares da autorização da introdução no mercado e pelas autoridades reguladoras.

    Introdução: Apesar de entidades raras, a incidência dos tumores malignos do intestino delgado parece estar a aumentar. O desenvolvimento da cápsula endoscópica e da enteroscopia assistida por balão permitiram um avanço na avaliação das lesões do intestino delgado. Temos como objetivo descrever as características clínicas e patológicas dos doentes com cancro do intestino delgado e averiguar o papel que estas técnicas endoscópicas assumem atualmente. Material e Métodos: Foi realizado um estudo retrospetivo dos doentes diagnosticados com cancro do intestino delgado, desde janeiro de 2010 até outubro de 2014. Os dados foram submetidos a análise estatística. Resultados: Dos 28 doentes diagnosticados, 54% eram do sexo feminino. A idade média ao diagnóstico foi de 61 anos. O tumor mais frequente foi o adenocarcinoma (n = 11), seguido do sarcoma (n = 6), linfoma (n = 6) e tumores neuroendócrinos (n = 3). A principal forma de apresentação esteve relacionada com perdas hemáticas ou obstrução intestinal. Ao diagnóstico, 46% dos doentes tinhammetástases distantes/tumor irressecável. A maioria dos tumores foi diagnosticada por técnicas endoscópicas (41%) ou imagiológicas (35%). No primeiro ano após o diagnóstico, 29% dos doentes faleceram. Na análise multivariada, o adenocarcinoma permaneceu fator independente para pior sobrevida. Discussão: Os doentes com adenocarcinoma apresentaram-se em estádios tardios e com tumores irressecáveis, contribuindo para um pior prognóstico. Ã necessário um elevado grau de suspeita clínica para o diagnóstico de cancro do intestino delgado. Conclusão: As características dos doentes foram globalmente consistentes com o descrito na literatura. A cápsula endoscópica e a enteroscopia assistida por balão são úteis no diagnóstico, gestão e vigilância do cancro do intestino delgado.

    Introdução: A Síndrome de Hiperestimulação Ovárica é uma complicação da hiperestimulação controlada do ovário realizada nos ciclos de reprodução medicamente assistida . O objetivo deste trabalho foi efetuar uma análise desses ciclos, para melhor compreensão daquela patologia, nomeadamente fatores de risco, formas de prevenção e tratamento da mesma e suas consequências. Materiais e Métodos: Análise retrospetiva de 4870 ciclos de reprodução medicamente assistida (2005 - 2011) com Síndrome de Hiperestimulação moderado (27) e grave (24). Foram estudados, os dados das características dos doentes, protocolos de estimulação, resultados embriológicos e clínicos, e tratamento efetuado. Resultados: No grupo com Síndrome de Hiperestimulação Ovárica a idade média foi inferior, a dose de rFSH + HMG foi mais baixa e os níveis de estradiol foram mais elevados. Nos grupos com Síndrome de Hiperestimulação, as taxas foram significativamente superiores para o número médio de ovócitos e blastocistos obtidos, de gravidez bioquímica e clínica, de implantação e de recém-nascidos. O parto muito pré-termo e a proporção de recém-nascidos com peso baixo e muito baixo foram superiores no grupo com Síndrome de Hiperestimulação Ovárica. As doentes com Síndrome de Hiperestimulação Ovárica grave foram hospitalizadas tendo apenas sido necessária medicação de suporte. Discussão: A Síndrome de Hiperestimulação Ovárica foi associada a condições de risco para o feto, nomeadamente prematuridade e baixo peso ao nascimento, devendo manter-se uma vigilância apertada da gravidez nestes casos. Conclusão: A idade jovem constitui um fator de risco de Síndrome de Hiperestimulação Ovárica e o nível de estradiol elevado foi preditor do mesmo, devendo levar à adoção de estratégias de prevenção.

    This work is presented as a theoretical essay on some facts from the history of astronomy analyzed according to the theory of reflective abstraction developed by Jean Piaget and collaborators (1970). Its aim is to understand the reasons that led to different astronomers, at the same historical period and culture, to "see" quite different evidences about the same phenomenon. In addition, we intend to facilitate the understanding of science as a human construction, subject to a time epoch and the ways of understanding of each scientist. Este trabajo se presenta como un ensayo teórico sobre algunos hechos históricos de la astronomía, analizados según la teoría de la abstracción reflexionante de Jean Piaget y sus colaboradores (1970). Se trata de comprender los motivos que llevaran a distintos astrónomos, de una misma época histórica y cultural, a "ver" diferentes evidencias sobre un mismo fenómeno. Además, se intenta posibilitar la comprensión de la ciencia como construcción humana, la cual es condicionada por su momento histórico y por las creencias y las formas de entender de los científicos.

    A trajetória evolutiva das estrelas de alta massa depende fortemente de suas taxas de perda de massa. Apesar do rápido progresso no estudo destas estrelas, a taxa de perda de massa e outros parâmetros físicos básicos, como a temperatura superficial e a velocidade terminal do vento ainda não estão bem determinados. Isto ocorre devido à presença de ventos irregulares, rápidos e fortes ao redor destas estrelas, tornando a interpretação dos seus espectros uma tarefa difícil. Assim, a modelagem do vento e da fotosfera dessas estrelas está sendo cada vez mais usada para obter tais parâmetros a partir dos espectros. O aumento da taxa de perda de massa durante a fase LBV (Variáveis Luminosas Azuis), comparado com outros tipos de estrelas, tem sido atribuído a instabilidades do tipo S Doradus. Dispomos de uma base de dados espectroscópicos cobrindo 22 anos de observações de AG Carinae, incluindo um ciclo S Doradus completo, com espectros CCD em alta resolução na faixa óptica e infravermelha. Utilizamos o programa desenvolvido por Schmutz (1997) para uma análise preliminar desse ciclo, obtendo a taxa de perda de massa a partir da linha do Ha. Não existe uma correlação clara da taxa de perda de massa com mudanças da temperatura efetiva, do raio da estrela e do fluxo na banda V. A estrela atingiu seu mínimo fotométrico (raio mínimo) em 1990 e o máximo fotométrico (raio máximo) em 1995, enquanto que o fluxo máximo da linha do Ha ocorreu em 1996. Além disso a taxa de perda de massa não segue esse ciclo, contrariamente às idéias correntes. Para fazer um modelo mais realista estamos usando o programa CMFGEN (Hillier & Miller), que trata a fotosfera e o vento estelar de forma consistente, considerando a radiação fora do equilíbrio termodinâmico (NLTE) e com blanketting total de linhas. Simulamos o espectro de AG Carinae em duas épocas extremas do ciclo S Dor para testar os resultados obtidos com o modelo mais simplificado.

  20. Camões e a cosmogonia

    Costa, J. M.

    2003-08-01

    Os Lusíadas, escrito por Luis de Camões em 1572, é um poema épico renascentista e a visão Cosmogônica do autor é apresentada, principalmente, no último canto do poema, quando Tétis mostra ao Gama a Máquina do Mundo. A Cosmogonia de Camões neste poema reflete uma visão de uma época de transição, que ainda não incorporou os elementos da revolução Copernicana. É uma visão Grego- Ptolomaica e também medieval. O poeta guia-se pela tradução e notas feita por Pedro Nunes, inventor do Nonio, do Tratado da Esfera "De Sphaera" do Astrônomo Inglês John Holywood, mais conhecido pelo nome latinizado de Johannes Sacrobosco. Outra provável fonte de Camões, de acordo com Luciano Antonio Pereira da Silva em Astronomia de os Lusíadas, é o "Theoricae novae Planetarum" (1460) do astrólogo Alemão Jorge Purbáquio (1423 - 1461). A Astronomia de Os Lusíadas representa a ciência do tempo de Camões. Camões nunca emprega a palavra constelação e seu catálogo é bastante completo. A Máquina do Mundo tem a Terra no centro. Em redor, em círculos concêntricos, a lua (Diana), Mercúrio, Vênus, o Sol (Febo), Marte, Júpiter e Saturno. Envolvendo estes astros tem o firmamento seguido pelo "Céu Áqueo" ou cristalino, depois o 1o Móbil, esfera que arrasta todas as outras consigo. Este trabalho, multidisciplinar, serve tanto para ensinar aos alunos da Física como das Ciências Humanas, a concepção de mundo do renascimento de uma forma belamente poética em versos decassílabos Este trabalho também ajuda na apreciação do maior clássico da língua portuguesa e mostra como as Ciências e as artes, em geral, estão correlacionadas e refletem a visão de mundo da época em que foi produzida.

    Introducción: la Aspergilosis Invasiva (AI) del Sistema Nervioso Central (SNC) es infrecuente y ocurre generalmente en pacientes inmunocomprometidos. Puede presentarse con cuadros de meningitis, aneurismas micóticos, infartos o abscesos. Es una infección con pronóstico reservado y puede afectar el SNC de forma primaria o secundaria a partir de un foco que se disemina por vía hematógena. Presentamos el caso de un paciente con AI con invasión primaria a nivel óseo y diseminación posterior al cerebro. Caso clínico: Paciente masculino de 25 años con diagnóstico de leucemia linfática aguda en tratamiento quimioterápico que presentó neumonitis por metotrexate por lo que inicia tratamiento con corticoides. Posteriormente agregó cervicalgia y con el diagnóstico de osteomielitis cervical se realiza punción bajo tomografía computada (TC) sin aislarse gérmenes. Se colocó Halo Vest e inició tratamiento antibiótico empírico. Posteriormente presentó afasia de expresión secundaria a lesión frontal izquierda. Se realizó evacuación de absceso cerebral aislando A. fumigatus. El tratamiento antibiótico específico posterior permitió una buena respuesta clínica y radiológica. Conclusión: La presencia de lesiones en el SNC de pacientes inmunocomprometidos debe incluir a las micosis como diagnóstico diferencial. La evacuación quirúrgica permite llegar rápidamente al diagnóstico mejorando la respuesta posterior al tratamiento antibiótico. Para evaluar la respuesta terapéutica y posibles recaídas se debe realizar un seguimiento periódico clínico radiológico.

    Variáveis Cataclísmicas são sistemas binários cerrados compostos de uma anã vermelha que transfere matéria para uma anã branca, em sistemas não magnéticos ocorre a formação de um disco de acresção em torno da anã branca. V3885 Sgr é uma variável cataclísmica classificada como sendo do tipo nova-like. É apresentado um estudo espectrofotométrico de V3885 Sgr de alta resolução temporal feito na região do visível. A região observada é centrada em Ha e abrange também a linha de HeI 6678. O primeiro resultado obtido neste estudo é a determinação do período orbital a partir de medidas da velocidade radial da linha de Ha como sendo 0,20716071(22) dias, resolvendo inconsistências quanto a esse valor na literatura e definindo uma efeméride a longo prazo para o sistema. Com este período e as medidas de velocidade radial do perfil de linha de Ha foi construído um diagrama de massas, através do qual restringimos as massas das componentes estelares do sistema e limitamos a inclinação orbital do sistema. Foram construídos diagramas de Greenstein para as linhas de Ha e HeI, onde os espectros médios em cada intervalo de fase são representados lado a lado em escala de cinza, indicando a existência de uma emissão intensa proveniente da parte posterior do disco. A partir da tomografia Doppler obtivemos perfis de emissividade radial para o disco tanto para a linha de Ha como para HeI. Os resultados obtidos são comparados com os de outros sistemas estudados com a mesma técnica. Serão apresentados também resultados da tomografia de flickering para o sistema.

    O método Grade of Membership (GoM) tem sido cada vez mais utilizado por demógrafos brasileiros e tem a vantagem de possuir um parâmetro que mensura a heterogeneidade individual, com base nas correlações não-observáveis entre as categorias de resposta das variáveis de interesse, gerando um medida do grau de pertencimento de cada indivíduo a perfis extremos. Alguns autores, contudo, chamam atenção para questões importantes na calibragem dos modelos finais que utilizam o programa GoM versão 3.4, como o problema de identificabilidade – soluções múltiplas para parâmetros estimados. Neste artigo, é sugerido um procedimento capaz de identificar um modelo final com solução única que descreva os tipos puros mais fidedignos à base de dados, em uma tentativa de otimização. Para ilustrar esse processo, utilizou-se uma base de dados correspondente a um levantamento econômico e sociodemográfico de uma população de pequenos agricultores residentes ao longo da Rodovia Transamazônica, no Estado do Pará. Também identificou-se a existência de instabilidade nos parâmetros estimados pelo programa GoM 3.4, sendo proposto um método de estabilização de seus valores. Com esses procedimentos combinados, os usuários do programa GoM 3.4 poderão descrever sua base de dados de forma mais adequada e responder às críticas sobre questões de identificabilidade e estabilidade dos modelos resultantes. Essas soluções empíricas são relevantes por afetarem cálculos de prevalência e de incidência de eventos de interesse, além de trazerem consequências importantes sobre o ponto e o momento corretos para intervenções de políticas públicas ou de planejamento prospectivo em análises de projeção.

    Introdução: A incidência das fraturas intertrocantéricas tem aumentado ao longo dos últimos anos, bem como todos os problemas a elas associados. É importante pesquisar possíveis formas de reduzir quer co-morbilidades, quer a mortalidade pós-operatória. Decidimos avaliar o impacto de alguns valores analíticos pré-operatórios na mortalidade pós-operatória de doentes com fractura intertrocantérica, com idade igual ou superior a 65 anos.Material e Métodos: De todas as fracturas intertrocantéricas admitidas entre Janeiro de 2007 e Maio 2012, 160 doentes foram incluídos no estudo. As variáveis estudadas foram idade, género, tempo de internamento, e dados analíticos, como hemoglobina, contagem de leucócitos e plaquetas, níveis de ureia e creatinina e concentração de sódio plasmática. Informação relativa à mortalidade foi obtida através do registo civil e, considerando um ponto de corte de seis meses após a cirurgia, os doentes foram divididos em dois grupos de acordo com a sua sobrevida. Os testes de Mann-Whitney e Chi-quadrado foram utilizados para estudar a associação entre as nossas variáveis e a sobrevida dos doentes.Resultados: A nossa população apresentava uma idade mediana de 82 anos de idade e uma maioria de mulheres (79,4%). Nos primeiros 6 meses após a cirurgia, 27 doentes dos iniciais 160 (16,1%) faleceram. A mortalidade estava relacionada com valores baixos de hemoglobina, elevados de plaquetas, elevados de creatinina e baixa concentração de sódio plasmático.Conclusão: A taxa de mortalidade pos-operatória da cirurgia da anca é elevada. Os nossos resultados podem ser utilizados parareduzir esta taxa, corrigindo valores analíticos pré-operatórios.

  5. Uma grade de perfis teóricos para estrelas massivas em transição

    2003-08-01

    Na XXVIII Reunião Anual da Sociedade Astronômica Brasileira (2002) apresentamos uma grade de perfis calculados de acordo com os pontos da trajetória evolutiva de metalicidade solar, Z = 0.02 e taxa de perda de massa () padrão, para estrelas com massa inicial de 25, 40, 60, 85 e 120 massas solares. Estes perfis foram calculados com o auxílio de um código numérico adequado para descrever os ventos de objetos massivos, supondo simetria esférica, estacionaridade e homogeneidade. No presente trabalho, apresentamos a complementação da grade com os perfis teóricos relativos às trajetórias de Z = 0.02 com taxa de perda de massa dobrada em relação a padrão (2´), e de metalicidade Z = 0.008. Para cada ponto das três trajetórias obtemos os perfis teóricos de Ha, Hb, Hg e Hd, e como esperado eles se apresentam em pura emissão, pura absorção ou em P-Cygni. Para valores de taxa de perda de massa muito baixos (~10-7) não há formação de linhas, o que é visto nos primeiros pontos em todas as trajetórias. Em geral, para um mesmo ponto a componente de emissão diminui e a absorção aumenta de Ha para Hd. É verificado que as trajetórias com Z = 0.02 e padrão possuem menos circuitos (loops) do que as com metalicidade Z = 0.02 e 2´ padrão, e seus perfis são, em geral, menos intensos. Em relação a trajetória de Z = 0.008, verifica-se menos circuitos e maior variação em luminosidade, e seus perfis mostram-se em, algumas trajetórias, mais intensos. Verificamos também que, pontos distintos em uma mesma trajetória, apresentam perfis diferentes para valores similares de luminosidade e temperatura efetiva. Sendo assim, uma grade de perfis teóricos parece ser útil para fornecer uma informação preliminar sobre o estágio evolutivo de uma estrela massiva.

    Tradicionalmente, as abundâncias em nebulosas planetárias e regiões HII têm sido obtidas de linhas excitadas colisionalmente, as quais são fortemente dependentes da temperatura eletrônica. Alternativamente, as abundâncias químicas podem ser determinadas de linhas de recombinação, as quais são quase independententes da temperatura eletrônica. Entretanto, consideráveis diferenças têm sido encontradas entre estes dois métodos. Estas discrepâncias têm sido atribuídas às flutuações espaciais da temperatura eletrônica. Entretanto, as magnitudes necessárias de flutuações de temperatura eletrônica são consideravelmente mais altas do que aquelas preditas pelos modelos padrões de fotoionização e os mecânismos físicos que poderiam explicar as grandes flutuações de temperatura são desconhecidas. Desta forma, o estudo de variações da temperatura eletrônica em regiões HII e nebulosas planetárias tem ganho um renovado interesse. Neste trabalho apresentamos os resultados preliminares de um estudo observacional sobre variações internas da temperatura eletrônica nas nebulosas planetárias NGC 2440 e NGC 2438. Analisamos dados espectrofotométricos de fenda longa, com alta razão sinal-ruído, na faixa de 3300-6800 Å, com o espectrógrafo Cassegrain Boller & Chivens acoplado ao telescópio de 1.52 m do European Southern Observatory (ESO). Temperaturas eletrônicas foram derivadas da razão [OIII](l4959+l5007)/l4363 em diferentes posições em cada nebulosa planetária. Flutuações da temperatura eletrônica foram detectadas e suas magnitudes foram estimadas em NGC 2440 e NGC 2438.

    Embora os Parâmetros Curriculares Nacionais do Ensino Médio (PCN-EM) e as orientações complementares a esses Parâmetros (PCN+) apontem a importância de uma abordagem significativa de conceitos relacionados à astronomia nas aulas de Física, muitos estudantes terminam o Ensino Médio (EM) sem compreender a razão de certos acontecimentos de origem celeste, ainda que estes façam parte de seu cotidiano. Este trabalho tem por objetivo analisar os conhecimentos básicos em astronomia dos alunos de EM da escola estadual Batista Renzi, bem como investigar os meios através dos quais estes conhecimentos foram adquiridos. Para tanto foi elaborado um questionário de múltipla escolha aplicado a 310 alunos distribuídos entre as três séries do EM dos períodos matutino e noturno. Dessa forma, observou-se que apenas 34,5% relacionaram as estações do ano à inclinação do eixo de rotação da Terra, 21,3% indicaram a influência gravitacional da Lua e do Sol como responsáveis pelo fenômeno das marés, 24,5% indicaram corretamente quais são os objetos celestes mais próximos da Terra, 36,1% identificaram ano-luz como uma medida de distância e 34,2% reconheceram uma estrela cadente como meteoro. Em contrapartida, 67,1% compreendiam a sucessão entre dia e noite, 73,9% identificaram o Sol como estrela e 52,3% relacionaram o Big Bang à origem do Universo. Além disso, foram comparadas as respostas de alunos de diferentes séries e períodos, observando-se, dentre outras coisas, que os estudantes do terceiro ano apresentam um percentual de acertos semelhante ao dos alunos do primeiro, caracterizando que a abordagem de tópicos relacionados à astronomia no EM não tem contribuído para uma maior compreensão dos fenômenos e conceitos.

    Introdução: Este estudo pretendeu caracterizar as trajetórias relacionais e reprodutivas conducentes à gravidez na adolescência em Portugal, explorando a existência de especificidades regionais.Material e Métodos: O estudo decorreu entre 2008 e 2013 em 42 serviços de saúde públicos. A amostra, nacionalmente representativa, incluiu 459 grávidas com idades entre os 12 e os 19 anos. Os dados foram obtidos por autorrelato, através de uma ficha de caracterização construída para o efeito.Resultados: Independentemente de terem tido um (59,91%) ou múltiplos parceiros sexuais (40,09%), as adolescentes engravidaram de forma mais frequente numa relação de namoro, utilizando contraceção à data da conceção e tendo identificado a falha contracetiva que esteve na origem da gravidez (39,22%). A nível regional, outras trajetórias surgiram com elevada prevalência, refletindo opções como a decisão de engravidar (Alentejo/Açores), a não utilização de contraceção (Centro/Madeira) ou a sua utilização ineficaz sem que a falha contracetiva fosse identificada (Madeira). As relações de namoro revelaram-se maioritariamente duradouras (> 19 meses), com homens mais velhos (> 4 anos) e fora do sistema de ensino (75,16%); estes resultados foram particularmente expressivos quando a gravidez foi planeada.Discussão: O conhecimento gerado por este estudo reflete a necessidade de investir em abordagens preventivas que atendam às necessidades específicas das jovens de cada região e integrem a população masculina de maior risco.Conclusão: Os nossos resultados podem contribuir para o delineamento de políticas de saúde mais eficazes e para uma atuação multidisciplinar mais informada ao nível da educação sexual e do planeamento familiar nas diferentes regiões do país.

    Introdução: Na prática odontológica, o Cirurgião-Dentista está sujeito aos efeitos nocivos provocados por diversos agentes, como pelo ruído emitido por seus instrumentos de trabalho. Em 1959, a American Dental Association recomendava avaliações audiométricas periódicas e uso de proteção auditiva. São necessárias maiores informações sobre o comportamento auditivo dessa população: Cirurgiões-Dentistas, Auxiliares e Protéticos para se propor medidas de prevenção e tratamento precoce.Objetivo: Investigar os limiares de audibilidade em Cirurgiões-Dentistas, Auxiliares e Protéticos.Método: Forma de estudo: Estudo Clínico.Participaram 108 profissionais, sendo 44 Cirurgiões-Dentistas (GI), 36 Auxiliares (G II) e 28 Protéticos (GIII). Foram realizadas: entrevista específica, meatoscopia, audiometria tonal convencional e de altas frequências, logoaudiometria, imitanciometria.Resultados: A comparação entre as médias dos limiares evidenciaram piora com o aumento da frequência para os 3 grupos testados; para a média tritonal de 500 a 2000Hz, e 3000 a 6000 Hz, o GIII apresentou os piores limiares, já para a média das altas frequências (9000 a 16.000Hz) o GII apresentou os piores limiares.Conclusão: A avaliação audiológica convencional não identificou exames alterados para os três grupos testados, no entanto, o exame da avaliação audiológica complementar como a audiometria de altas frequências indicou maior sensibilidade na detecção precoce de alterações auditivas uma vez que a perda auditiva dessa população acomete as frequências que não são testadas nos exames convencionais. Dessa maneira enfatizamos nesse trabalho a necessidade de inserir na rotina de exames a audiometria de altas frequências juntamente com os outros exames audiológicos.

    Introdução: Em tecidos e órgãos expostos a ruído de baixa frequência de alta amplitude ocorre fibrose na ausência de sinais inflamatórios, que se pensa ser uma resposta protetora. No tecido conjuntivo perivasculo-ductal da glândula parótida seguem artérias, veias e a árvore ductal. Crê-se que o tecido conjuntivo perivasculo-ductal funcione como um estabilizador mecânico do tecido glandular.Material e Métodos: Para quantificar a proliferação de tecido conjuntivo perivasculo-ductal em ratos expostos a ruído de baixafrequência de alta amplitude foram utilizados 60 ratos Wistar igualmente divididos em seis grupos. Um grupo mantido em silêncio, e os restantes 5 expostos a ruído de baixa frequência de alta amplitude continuamente: g1-168h (1 semana); g2-504h (3 semanas); g3-840h (5semanas); g4-1512h (9 semanas) e g5-2184h (13 semanas). Após a exposição, as parótidas foram removidas e o tecido conjuntivo perivasculo-ductal foi medido em todos os grupos. Foi efectuada análise estatística com ANOVA por SPSS 13.0.Resultados: A tendência é um aumento global das áreas do tecido conjuntivo perivasculo-ductal, que se desenvolve de forma linear e significativa com o tempo de exposição (p < 0,001).Discussão: Tem sido sugerido que a resposta biológica à exposição ao ruído de baixa frequência de alta amplitude está associada à necessidade de manter a integridade estrutural. O reforço estrutural seria conseguido através do aumento do tecido conjuntivo perivasculo-ductal.Conclusões: Assim, estes resultados mostram que o tecido conjuntivo perivasculo-ductal aumenta em resposta à exposição ao ruído de baixa frequência de alta amplitude.

    Introdução: A Escala de Níveis de Consciência Emocional (LEAS) foi desenvolvida para avaliar o constructo consciência emocional, numa perspectiva cognitivo-desenvolvimentista e influenciada pelas Teorias de Piaget e Werner. É composta por 20 situações ou cenários que evocam emoções e tem sido usada em múltiplas investigações nos domínios da regulação emocional, alexitimia e perturbações psiquiátricas. Trata-se de uma medida bem documentada, validada e precisa. Em virtude da sua extensão, alguns investigadores têm vindo a utilizar uma das formas paralelas que compõe a versão completa, a LEAS-A, sendo contudo notória a vacuidade de estudos que descrevam as qualidades psicométricas desta versão. Face à inexistência de uma medida de caracterização da organização da experiência emocional para a população portuguesa, desenvolveu-se a versão portuguesa da LEAS, caracterizaram-se diversos indicadores de precisão e validade, assim como para a versão reduzida LEAS-A. Materiais e Métodos: Foram desenvolvidos três estudos com estas versões, dois deles com recurso a estudantes universitários e um outro com uma amostra da população em geral. Resultados: A versão portuguesa demonstrou níveis elevados de precisão, mais robustos do que os encontrados em estudos de adaptação da escala noutros países. A LEAS-A apresentou bons níveis de precisão e indicadores de validade discriminante e concorrente. As pontuações obtidas na LEAS-A mostraram-se independentes da presença de afecto negativo e associaram-se significativamente a um estilo cognitivo externalizado, próprio do funcionamento alexitímico. Conclusões: As versões portuguesas da LEAS e da LEAS-A apresentam qualidades psicométricas muito adequadas, o que permite o seu uso científico. São discutidas as implicações da sua utilização nos contextos clínico e de investigação.

Amid the diversity of uses and concepts, we recognize the need for rigorous conceptual demarcation about networks in the field of health. Such concern aims to preserve the strategic potential of this concept in the research and planning in the field, overcoming uncertainties and distortions still observed in its discourse-analytic circulation in public health. To this end, we will introduce the current uses of network in different disciplinary fields, emphasizing dialogues with the field of public health. With this, we intend to stimulate discussions about the development of empirical dimensions and analytical models that may allow us to understand the processes produced within and around health networks.

Para tanto, apresentaremos os usos correntes de rede em diferentes campos disciplinares, destacando interlocuções com o campo da saúde coletiva. Com isso, pretendemos estimular o debate acerca do desenvolvimento de dimensões empíricas e modelos de análise que permitam compreender os processos produzidos no interior e ao redor

    Objetivo Descrever as experiências recentes com a aplicação de sistemas de apoio à decisão clínica em gastroenterologia, de forma a estabelecer o nível de desenvolvimento, testes e vantagens conferidas à prática médica com a introdução desses softwares. Métodos Foi realizada busca nas bases de dados PubMed, LILACS e ISI Web of Knowledge, utilizando termos relacionados à sistemas de apoio à decisão e à gastroenterogia, incluindo artigos originais publicados no período entre 2005 e 2010. Foram recuperadas 104 publicações, na busca inicial e, após a aplicação dos critérios de inclusão e exclusão, foram eleitos nove estudos para leitura do texto completo. Resultados Os sistemas de apoio à decisão clínica apresentam grande multiplicidade de problemas clínicos e investigação de doenças. Em 89% dos casos, são descritos modelos experimentais para o desenvolvimento de sistemas de apoio à decisão clínica. A descrição dos resultados obtidos por técnicas de inteligência artificial em 78% das publicações. Em dois dos estudos foram realizadas comparações com o médico e em apenas uma publicação um estudo controlado foi descrito, mostrando evidências de melhorias na prática médica. Conclusão Os estudos mostram potenciais benefícios dos sistemas de apoio à decisão clínica à prática médica, porém, estudos controlados em ambiente real devem ser realizados para comprovar esta perspectiva.

    "Imagens do Céu Ontem e Hoje" é o título de uma nova exposição que está sendo inaugurada no Museu de Astronomia e Ciências Afins (MCT), que inclui experimentos interativos, maquetes, réplicas e 8 terminais de computador com um multimídia interativo sobre Astronomia para consulta dos visitantes. O multimídia apresenta um conteúdo bastante extenso, que engloba quase todos os temas em Astronomia, consistindo numa fonte de divulgação e pesquisa para um público que vai das crianças até estudantes universitários. O conteúdo está distribuído em mais de 500 páginas de texto divididas em 4 módulos: "O Universo", "Espectroscopia", "Telescópios" e "Observando o Céu". Cada módulo é subdividido em 5 seções, em média, cada uma iniciada por uma animação que ilustra os temas a serem abordados na seção. Ao final da animação, uma lista de temas é apresentada sob o título "Saiba Mais". Para exemplificar, o módulo "O Universo" contém as seguintes seções: "O Universo visto pelo homem", "Conhecendo o Sistema Solar", "Indo além do Sistema Solar", "Nossa Galáxia, a Via-Láctea" e "Indo mais além, a imensidão do Universo". A seção "Conhecendo o Sistema Solar", por sua vez, tem os seguintes temas: "A origem do Sistema Solar", "O Sol", "Os planetas", "Satélites, asteróides, cometas e outros bichos..." e "O Sistema Solar em números". Cada texto é repleto de imagens, quadros, desenhos, esquemas, etc, além de passatempos ao final de cada seção, incluindo jogos interativos, quadrinhos e curiosidades, que auxiliam o aprendizado de forma divertida. Apresentamos neste trabalho as idéias gerais que permearam a produção da exposição, e uma viagem pelo multimídia para exemplificar sua estrutura e conteúdo. O multimídia será posteriormente disponibilizado para o público externo pela página eletrônica do MAst e/ou por intermédio de uma publicação comercial.

  18. Compilação de dados atômicos e moleculares do UV ao IV próximo para uso em síntese espectral

    Espectros sintéticos são utéis em uma grande variedade de aplicações, desde análise de abundâncias em espectros estelares de alta resolução ao estudo de populações estelares em espectros integrados. A confiabilidade de um espectro sintético depende do modelo de atmosfera adotado, do código de formação de linhas e da qualidade dos dados atômicos e moleculares que são determinantes no cálculo das opacidades da fotosfera. O nosso grupo no departamento de Astronomia no IAG tem utilizado espectros sintéticos há mais de 15 anos, em aplicações voltadas principalmente para a análise de abundâncias de estrelas G, K e M e populações estelares velhas. Ao longo desse tempo, as listas de linhas vieram sendo construídas e atualizadas continuamente, e alguns acréscimos recentes podem ser citados: Castilho (1999, átomos e moléculas no UV), Schiavon (1998, bandas moleculares de TiO) e Melendez (2001, átomos e moléculas no IV próximo). Com o intuito de calcular uma grade de espectros do UV ao IV próximo para uso no estudo de populações estelares velhas, se fazia necessário compilar e homogeneizar as diversas listas em apenas uma lista atômica e uma molecular. Nesse processo, a nova lista compilada foi correlacionada com outras bases de dados (NIST, Kurucz Database, O' Brian et al. 1991) para atualização dos parâmetros que caracterizam a transição atômica (comprimento de onda, log gf e potencial de excitação). Adicionalmente as constantes de interação C6 foram calculadas segundo a teoria de Anstee & O'Mara (1995) e artigos posteriores. As bandas moleculares de CH e CN foram recalculadas com o programa LIFBASE (Luque & Crosley 1999). Nesse poster estão detalhados os procedimentos citados acima, as comparações entre espectros calculados com as novas listas e espectros observados em alta resolução do Sol e de Arcturus, e uma análise do impacto decorrente da utilização de diferentes modelos de atmosfera no espectro sintético.

  19. Emissão de hidrogênio molecular e [FeII] em núcleos Seyfert

    Um dos problemas fundamentais em núcleos ativos de galáxias (AGN) é determinar os mecanismos de excitação dominantes do gás emissor de linhas estreitas, seja este excitado por mecanismos não-estelares (fotoionização por uma fonte central ou choques produzidos por um jato rádio no gás circumnuclear) ou estelares (fotoionização por estrelas OB ou choques originados por um remanescente de supernova em expansão). Essa ambiguedade se faz mais evidente ao intepretar o espectro de espécies tais como H2 e [FeII]. Na primeira, fluorescência UV, processos térmicos (choques e/ou aquecimento por fótons) ou illuminação por raios-x, podem ser responsáveis pelo espectro observado enquanto que na segunda, os dois últimos mechanismos seriam relevantes. Neste trabalho, utilizando espectroscópia JHK de média resolução para uma amostra de AGN encontramos que o H2 observado é gerado principalmente por processos térmicos associados à presença de episódios de formação estelar circumnuclear. No entanto, em galáxias tais como NGC4151 as observações mostram que o hidrogênio molecular origina-se, principalmente, da interação entre o jato radio e o gás da NLR. Esses resultados baseiam-se nos valores das razões de linhas H2 2.24/2.12 mm e H2 2.03/2.22 mm. H2 2.24/2.12 separa claramente processos não-térmicos dos térmicos enquanto H2 2.03/2.22 serve como indicador de temperatura da componente térmica, e portanto, discrimina entre choques e associações OB. Já para o [FeII], as observações são compatíveis com excitação produzida diretamente pela fonte central ou choques associados com o jato rádio. A comparação da largura dos perfis de linhas observados permite concluir que não há correlação entre a emissão de H2 e [FeII]. Em praticamente todos os casos analisados, os perfis das linhas de H2 são não-resolvidos, enquanto que os perfis de [FeII] indicam, em alguns casos, velocidades de até 600 km/s.

  20. Transcriptional activation of the herpes simplex virus type 1 UL38 promoter conferred by the cis-acting downstream activation sequence is mediated by a cellular transcription factor.

    The herpes simplex virus (HSV) type 1 strict late (gamma) UL38 promoter contains three cis-acting transcriptional elements: a TATA box, a specific initiator element, and the downstream activation sequence (DAS). DAS is located between positions +20 and +33 within the 5' untranslated leader region and strongly influences transcript levels during productive infection. In this communication, we further characterize DAS and investigate its mechanism of action. DAS function has a strict spacing requirement, and DAS contains an essential 6-bp core element. A similarly positioned element from the gamma gC gene (UL44) has partial DAS function within the UL38 promoter context, and the promoter controlling expression of the gamma US11 transcript contains an identically located element with functional and sequence similarity to UL38 DAS. These data suggest that downstream elements are a common feature of many HSV gamma promoters. Results with recombinant viruses containing modifications of the TATA box or initiator element of the UL38 promoter suggest that DAS functions to increase transcription initiation and not the efficiency of transcription elongation. In vitro transcription assays using uninfected HeLa nuclear extracts show that, as in productive infection with recombinant viruses, the deletion of DAS from the UL38 promoter dramatically decreases RNA expression. Finally, electrophoretic mobility shift assays and UV cross-linking experiments show that DAS DNA forms a specific, stable complex with a cellular protein (the DAS-binding factor) of approximately 35 kDa. These data strongly suggest that the interaction of cellular DAS-binding factor with DAS is required for efficient expression of UL38 and other HSV late genes. Images PMID:7966567

    Introduccion. La lesion medular es un evento catastrofico, cuyas consecuencias persisten durante toda la vida del paciente. La investigacion en tratamiento se ha basado principalmente en el desarrollo de terapias que reduzcan la discapacidad, pero desde los anos noventa hay un avance significativo y se han probado varios trasplantes celulares en modelos animales de lesion medular, celulas de Schwann, astrocitos y celulas de la glia envolvente olfatoria (CGEO). Objetivo. Hacer un recuento detallado de la patogenia de la lesion medular primaria y secundaria y de los mecanismos por los cuales las CGEO inducirian sus posibles efectos regenerativos descritos en la bibliografia. Desarrollo. Despues del traumatismo, la lesion se desarrolla en dos fases, la primaria se caracteriza por las lesiones de compresion y la secundaria se produce por una serie de factores que se dan en paralelo y que incluyen factores vasculares, celulares, moleculares y formacion de cicatriz glial. La mayoria de los modelos de lesion medular y trasplante con CGEO han comunicado recuperacion funcional, remielinizacion y regeneracion axonal. Estas celulas ejercen su accion de manera indirecta a traves de la produccion de factores de crecimiento y de manera directa induciendo regeneracion neuronal, axonal y remielinizacion. Conclusiones. Las CGEO son una opcion terapeutica en pacientes con lesion medular debido a que inducen de modo directo o indirecto regeneracion neuronal, axonal, remielinizacion de axones, disminucion de cicatriz glial y otros efectos que conducen a la recuperacion funcional.

    Introducción: en 2011 ocurrieron 955 defunciones maternas en México, 49.9 por 100 000 nacidos vivos. La meta de la Organización Mundial de la Salud para 2015 es reducir la tasa a 22.5: 560 defunciones anuales. Métodos: estudio descriptivo y retrospectivo de 1257 muertes maternas ocurridas en México durante 2009, con una muestra representativa de 173 expedientes. Se calcularon frecuencias simples y porcentajes. Resultados: las muertes maternas ocurrieron por causas directas como preeclampsia-eclampsia, infección y hemorragia obstétrica secundaria a atonía uterina, acretismo placentario y placenta previa. Quince mujeres tuvieron complicaciones por abortos. Cuatro murieron por embarazo extrauterino debido a diagnóstico y tratamiento tardíos. Las causas indirectas de la muerte materna fueron neoplasias, sepsis abdominal, eventos vasculares, problemas metabólicos y cardiopatías. Veinticinco pacientes fallecieron por neumonía atípica y 11 por influenza A H1N1. Conclusiones: es factible disminuir la mortalidad materna mediante suficientes consultas prenatales de calidad y evitar embarazos con riesgo alto por los antecedentes obstétricos y los padecimientos asociados. La influenza A H1N1 interrumpió la tendencia descendente de la mortalidad materna.

    Objectives To explore whether changes in a composite (power Doppler/greyscale ultrasound (PDUS)) synovitis score, developed by the OMERACT-EULAR-Ultrasound Task Force, predict disease activity outcomes in rheumatoid arthritis (RA). Methods Patients with RA who were methotrexate inadequate responders starting abatacept were evaluated. Individual joint PDUS scores were combined in the Global OMERACT-EULAR Synovitis Score (GLOESS) for metacarpophalangeal joints (MCPs) 2–5, all joints (22 paired) and a reduced (9 paired) joint set. The predictive value of changes in GLOESS at week 1–16 evaluations for clinical status and response (Disease Activity Score (DAS)28 (C reactive protein, CRP) <2.6; DAS28(CRP) ≤3.2; DAS28(CRP) ≥1.2 improvement) up to week 24, and correlations between DAS28 and GLOESS were assessed. Results Eighty-nine patients completed the 24-week treatment period. Changes in GLOESS (MCPs 2–5) from weeks 1 to 16 were unable to predict DAS28 outcomes up to week 24. However, significant improvements in GLOESS (MCPs 2–5) were observed at week 12 in patients with DAS28 ≥1.2 improvement at week 24 versus those who did not achieve that clinical response. In patients achieving DAS28 ≥1.2 improvement or DAS28 ≤3.2 at week 24, changes in GLOESS (22 and 9 paired joint sets) were greater in patients who already achieved DAS28 ≥1.2 at week 12 than in those who did not. No significant correlations were found between changes in DAS28 and GLOESS definitions at any time point. Conclusions PDUS was not correlated with clinical status or response as measured by DAS28-derived criteria, and PDUS changes were not predictive of clinical outcome. The discrepancies require further exploration. Trial registration number NCT00767325; Results. PMID:27175297

    O presente trabalho é parte preliminar de um estudo mais amplo em nível de doutorado sobre o ensino de astronomia mediado pelas tecnologias da informação e comunicação, utilizando dispositivos compactos, móveis e pessoais. Este estudo também faz parte do projeto institucional do CEFETMG sobre ambientes diversificados de aprendizagem sob fomento da agência estadual FAPEMIG (Fundação de Amparo à Pesquisa do Estado de Minas Gerais). Esta apresentação aborda o resultado das concepções prévias de estudantes em relação a conhecimentos básicos de astronomia, ligados à percepção e observação direta do céu. Três turmas de estudantes de 1ª série e uma turma de 3ª série do ensino integrado médio técnico da Educação Básica, Técnica e Tecnológica (EBTT) do CEFETMG Campus II - Belo Horizonte/MG foram submetidas a uma avaliação prévia através de questionário estruturado. Este questionário foi elaborado de forma a abordar a percepção dos estudantes em relação aos recursos gráficos (figuras e desenhos) representativos de conhecimentos básicos de astronomia, comuns em livros didáticos. Após a análise dos resultados desta avaliação, organizou-se uma estratégia de intervenção didática em sala de aula sobre o conteúdo de astronomia, utilizando-se de recursos de mediação baseados nas tecnologias da informação e comunicação. Os temas selecionados para esta estratégia didática foram relacionados aos assuntos básicos de astronomia em que ocorreu maior nível de desconhecimento dos estudantes. Os estudantes foram submetidos a avaliação posterior elaborada com os mesmos pressupostos da avaliação prévia. A análise dos resultados foi realizada a partir dos pressupostos da aprendizagem significativa (Ausubel; Novak e Hanesian, 1983). O ensino de astronomia por mediação das tecnologias da informação e comunicação indica uma alternativa preliminar aos trabalhos de campo usuais orientados na prática escolar, tais

    students´ teams. O docente tem importância fundamental no programa de pós-graduação, pois é quem planeja e executa grande parte das tarefas, sendo também o responsável por difundir conhecimentos aos alunos. O professor deve utilizar recursos didáticos que o qualifiquem continuamente, criando condições favoráveis para que o aluno se desenvolva e aprenda da melhor maneira e com mais facilidade. A homogeneidade no grupo de pós-graduação consiste da presença de subgrupos de pesquisa correspondentes às Áreas de Concentração, onde cada subgrupo trabalhe com algumas linhas de pesquisas diversificadas. É desejável que o corpo docente tenha significativa produção científica, de qualidade e distribuída homogeneamente entre os docentes. Estes devem sistematicamente buscar recursos em agências de fomento para pesquisa, tanto para o custeio dos estudos, quanto para a valorização dos pesquisadores envolvidos em todas as atividades. Os programas de pós-graduação precisam investir na formação de seus docentes, os quais devem aprimorar seus conhecimentos em epidemiologia de estudos clínicos, ética em pesquisa e em didática. Duas das características do sistema de pós-graduação no Brasil são a nucleação e a solidariedade, embasadas na capacidade e/ou interesse dos mais estruturados se solidarizarem com os programas iniciantes, cooperando com as suas atividades. A Capes valoriza a inserção social no contexto das atividades dos programas de pós-graduação, prevendo nos critérios de avaliação o reconhecimento de atividades com impacto tecnológico, cultural, educacional e social. Existe um modelo ideal de pós-graduação? Partimos do pressuposto de que não há uma fórmula matemática ou modelo ideal de pós-graduação e sim que cada instituição deve se adequar e buscar aperfeiçoar seu corpo docente e discente.

    reconocen que una estrella es formada por una masa de gas; varios conocimientos previos parten de aspectos puramente visuales; por otro lado, los estudiantes no tienen el hábito de observar la naturaleza detalladamente, entre otros problemas. Vemos esta investigación como una probable fuente de referencia en la que los profesores de ciencias pueden reconocer la importancia del conocimiento previo, y la forma como interfieren con su práctica de enseñanza, además de la adquisición de recursos para la planificación de sus clases. Com base em leituras de artigos relacionados ao ensino de Astronomia publicados no Brasil, verificou-se a inexistência de investigações sobre o conhecimento prévio de estudantes acerca das características físicas das estrelas, fato que nos motivou a desenvolver a pesquisa apresentada. Os conhecimentos prévios de 125 estudantes do primeiro ano do ensino médio constituíram os dados do estudo, os quais foram inferidos através da análise das respostas cedidas em questionários impressos (Apêndice A). A partir da análise de conteúdo dessas respostas tornou-se possível realizar algumas inferências como, por exemplo: vários estudantes possuem dificuldade em elaborar um modelo explicativo sobre o funcionamento de uma estrela; são poucos os que dizem que as estrelas possuem certo tempo de existência; alguns alunos as imaginam com pontas; poucos reconhecem que uma estrela é formada por uma massa de gás; vários conhecimentos prévios partem de aspectos meramente visuais; ainda assim, os estudantes não possuem o hábito de observar a natureza mais detalhadamente, entre outras. Vemos essa pesquisa como uma provável fonte de consulta na qual os professores de ciências poderão, além de reconhecer a importância dos conhecimentos prévios para o ensino e como eles interferem em sua prática, adquirir subsídios para o planejamento de suas aulas.

    percepción limitada que los estudiantes tienen de su alrededor la cual, sin embargo, se expandió debido a las actividades llevadas a cabo, sobre todo en relación con la Luna. Trabajar con medidas sistemáticas revela el manejo cuidadoso de los datos para que sean comprensibles para los estudiantes, así como el trabajo con las sombras para que comprendan primero como se forman estas para después trabajarlas en Astronomía. Por último, llegamos a la conclusión de que el proceso desarrollado consistió en una etapa inicial de una obra que debe ser profundizado en los años posteriores de la formación de estos estudiantes. Projeto de pesquisa desenvolvido com 95 alunos do 6º ano do Ensino Fundamental de uma escola pública estadual de Uberlândia, Minas Gerais. Foi um trabalho contínuo, de fevereiro a dezembro de 2013, o qual levou os alunos a participarem de atividades de observação do entorno, dentre ele, o céu, analisando as mudanças ocorridas. Focamos no estudo das variações de temperaturas, chuvas, duração do dia, variações do tamanho das sombras e mudanças nos aspectos da Lua. Nosso foco de análise centrou-se em discutir os conhecimentos que os referidos alunos tinham acerca dos temas indicados no início e ao término da implementação da proposta. Os resultados mostraram a percepção limitada que os estudantes possuem de seu entorno, todavia, ampliada em função das atividades desenvolvidas, principalmente no que se refere à Lua. O trabalho com medidas sistemáticas revela o cuidado no tratamento dos dados para que eles se tornem compreensíveis aos alunos, assim como o trabalho com as sombras sinaliza para que os alunos primeiramente compreendam como as sombras são formadas para depois trabalhar isso em Astronomia. Por fim, concluímos que o processo vivido constituiu-se em uma etapa inicial de um trabalho que deve ser estimulado para os anos subsequentes da formação desses alunos.
