    Full Text Available RESUMEN Antecedentes: En anatomía patológica, existen variedad de agentes químicos que deben ser controlados. Por su potencial cancerígeno destacan el Formaldehído (CH2O, Xileno y los Compuestos Orgánicos Volátiles (COVs. Objetivo: Valorar la eficacia del uso de purificadores mediante la fotocatalización y los sistemas de friocongelación, para el control de los niveles de exposición a CH2O, Xileno y COVs. Objetivo Secundario: Comparar mediciones de Formaldehído con otros 3 hospitales de la Comunidad de Madrid. Metodología: Se realizaron 26 mediciones ambientales en Anatomía Patológica del Hospital Universitario de Fuenlabrada (HUF, en febrero del año 2017 y en marzo del mismo año, posterior a la instalación de los purificadores y sistemas de friocongelación, en las áreas de laboratorio y sala de tallado. Se valora Xileno y COVs con el método PID (detector de fotoionización, PID por sus siglas en inglés, PhotoIonization Detector y de CH2O a través de un Sistema de Detección de Gas. Como criterio para valorar la exposición a COVs se tomó como gas de referencia el isobutileno con un VLA-EC de 100 ppm. Para el Xileno se compararon los resultados con el VLA-EC 100 ppm y para el CH2O con el VLA-EC de 0,3 ppm, establecidos en la guía de «Límites de Exposición Profesional para Agentes Químicos» del Instituto Nacional de Seguridad e Higiene en el Trabajo. Resultados: Los niveles de exposición previos no superaban los valores límites. Se observó que tras la implantación de las medidas preventivas colectivas estos valores disminuyeron, obteniéndose resultados estadísticamente significativos: COVs (p= 0.0002; IC 95% 2.393- 5.506, Xileno (p= 0.0002; IC 95% 1.021- 2.359 y CH2O (p= 0.0004; IC 95% 0.210-0.350. Conclusiones: El sistema integral de friocongelación y purificación mediante fotocatalización optimizan el control de la exposición a dichos agentes químicos, anulando las fuentes de emisión.

    Full Text Available This study was designed to investigate the DNA-methylation status of <em>E>-cadherin (<em>CDH1em> and <em>H>-cadherin (<em>CDH13em> in serum samples of cervical cancer patients and control patients with no malignant diseases and to evaluate the clinical utility of these markers. DNA-methylation status of <em>CDH1em> and <em>CDH13em> was analyzed by means of MethyLight-technology in serum samples from 49 cervical cancer patients and 40 patients with diseases other than cancer. To compare this methylation analysis with another technique, we analyzed the samples with a denaturing high performance liquid chromatography (DHPLC PCR-method. The specificity and sensitivity of <em>CDH1em> DNA-methylation measured by MethyLight was 75% and 55%, and for <em>CDH13em> DNA-methylation 95% and 10%. We identified a specificity of 92.5% and a sensitivity of only 27% for the <em>CDH1em> DHPLC-PCR analysis. Multivariate analysis showed that serum <em>CDH1em> methylation-positive patients had a 7.8-fold risk for death (95% CI: 2.2–27.7; <em>p> = 0.001 and a 92.8-fold risk for relapse (95% CI: 3.9–2207.1; <em>p> = 0.005. We concluded that the serological detection of <em>CDH1em> and <em>CDH13em> DNA-hypermethylation is not an ideal diagnostic tool due to low diagnostic specificity and sensitivity. However, it was validated that <em>CDH1em> methylation analysis in serum samples may be of potential use as a prognostic marker for cervical cancer patients.

    Full Text Available RESUMO Foi estudada a remoção de compostos BTEX (benzeno, tolueno, etilbenzeno e xilenos em reator de escoamento contínuo e mistura perfeita, com inóculo de Aspergillus niger AN 400, operado sob o tempo de detenção hidráulica (TDH de 12 horas para avaliar a eficiência do sistema na biorremediação de água poluída com gasolina na presença (Etapa I e na ausência (Etapa II de glicose (0,5 g.L-1. A água poluída com gasolina foi preparada na proporção de 10:1000 mL (gasolina:água. Na primeira etapa foi ainda estudada a influência da adição de nutrientes no afluente sobre a eficiência do processo. A adição de nutrientes foi benéfica ao processo e, mesmo com a retirada da glicose, a eficiência foi mantida, devido à metabolização do etanol - presente na gasolina brasileira em 25% - pelos fungos, sendo ambos fontes de carbono de assimilação mais fácil para obtenção de energia; o etanol e a glicose, foram usados como cossubstratos na degradação dos BTEX. Assim, na Etapa 2, quando somente havia o etanol no meio, chegou-se a percentuais médios de 88% para benzeno, 90% para tolueno, 90% para etilbenzeno, e de 91% para meta, para e orto-xileno (m, p e o-xileno, com formação de subprodutos fenólicos. A população fúngica predominou no meio ao longo de toda a operação do reator.

    Full Text Available Se determinaron los niveles de benceno,tolueno y xilenos (BTX en el aire deuna industria de pinturas adscrita al InstitutoColombiano de Seguros Sociales,con el propósito de evaluar el riesgo ocupacional ocasionado por el uso de estos solventes; se compararon estos resultados con los valores límite umbral (Threshold Limit Valué , TLV. Se escogió como estrategia de muestreo la metodología de período parcial con muestras consecutivas y se utilizaron tubos de carbón activado como medio de captación de solventes. La extracciónse hizo con disulfuro de carbono y se utilizó como método de análisis la cromatografía de gases con detector de ionización de llama. Se encontró que el método es altamente selectivo porque aun en presencia de otros 10 solventes utilizados en la industria de pinturas, fue posible encontrar una buena separación para BTX. La precisión, expresada como coeficiente de variación, fue menor al 10%, la exactitud varió entre 85 y 99% para los tres disolventes. Se encontraron concentraciones en aire que variaron entre no detectable y 55,1 mg/m3 para el benceno; entre 18,3 y 253 mg/m3 para tolueno; entre 11,8 y 122,2 mg/m3 para xileno. Los valores TLV de benceno, tolueno y xilenos, corregidos de acuerdo con el modelo de Brief y Scala para una jornada diaria de 10 horas fueron de 1,1, 132 y 304 mg/m3 respectivamente. Se encontró que existe riesgo ocupacional por benceno en algunos puestos de trabajo, lo cual es preocupante si se tiene en cuenta que éste no es utilizado como materia prima en la fabricación de pinturas. El tolueno presenta riesgo ocupacional en menor proporción mientras que la presencia de xilenos no genera riesgo porque las concentraciones encontradas no superaron el valor TLV. Se determinó que existe riesgo ocupacional en la mayoría de los puestos de trabajo de la industria estudiada cuando se considera la mezcla de los tres disolventes.

    non-cubic EoS models, such as the Perturbed Chain Statistical Associating Fluid Theory (PC-SAFT) EoS and the Soave modified Benedict-Webb-Rubin (Soave-BWR) EoS, may partly replace the roles of these classical cubic models in the upstream oil industry. Here, we attempt to make a comparative study...... for the four models. For PVT prediction, the non-cubic models show advantages in some high pressure high temperature (HPHT) fluids but no clear advantages in general, indicating the necessity for further improvement of the characterization procedure....

    Full Text Available The reliability of implantable blood sensors is often hampered by unspecific adsorption of plasma proteins and blood cells. This not only leads to a loss of sensor signal over time, but can also result in undesired host vs. graft reactions. Within this study we evaluated the hemocompatibility of isocyanate conjugated star shaped polytheylene oxide—polypropylene oxide co-polymers NCO-sP(EO-stat-PO when applied to gold surfaces as an auspicious coating material for gold sputtered blood contacting sensors. Quartz crystal microbalance (QCM sensors were coated with ultrathin NCO-sP(EO-stat-PO films and compared with uncoated gold sensors. Protein resistance was assessed by QCM measurements with fibrinogen solution and platelet poor plasma (PPP, followed by quantification of fibrinogen adsorption. Hemocompatibility was tested by incubation with human platelet rich plasma (PRP. Thrombin antithrombin-III complex (TAT, β-thromboglobulin (β-TG and platelet factor 4 (PF4 were used as coagulation activation markers. Furthermore, scanning electron microscopy (SEM was used to visualize platelet adhesion to the sensor surfaces. Compared to uncoated gold sensors, NCO-sP(EO-stat-PO coated sensors revealed significant better resistance against protein adsorption, lower TAT generation and a lower amount of adherent platelets. Moreover, coating with ultrathin NCO-sP(EO-stat-PO films creates a cell resistant hemocompatible surface on gold that increases the chance of prolonged sensor functionality and can easily be modified with specific receptor molecules.

    Core-collapse supernovae eject huge amount of flux of energetic neutrinos which affect explosive nucleosynthesis of rare isotopes like {sup 7}Li, {sup 11}B, {sup 92}Nb, {sup 138}La and Ta and r-process elements. Several isotopes depend strongly on the neutrino flavor oscillation due to the Mikheyev-Smirnov-Wolfenstein (MSW) effect. We here discuss how to determine the neutrino temperatures and propose a method to determine still unknown neutrino oscillation parameters, mass hierarchy and θ{sub 13}, simultaneously. Combining the recent experimental constraints on θ{sub 13} with isotopic ratios of the light elements discovered in presolar grains from the Murchison meteorite, we show that our method suggests at a marginal preference for an inverted neutrino mass hierarchy. We also discuss supernova relic neutrinos that may indicate the softness of the equation of state (EoS) of nuclear matter as well as adiabatic conditions of the neutrino oscillation.

  14. On Application of Non-cubic EoS to Compositional Reservoir Simulation

    DEFF Research Database (Denmark)

    Yan, Wei; Michelsen, Michael Locht; Stenby, Erling Halfdan

    Compositional reservoir simulation uses almost exclusively cubic equations of state (EoS) such as the SRK EoS and the PR EoS. This is in contrast with process simulation in the downstream industry where more recent and advanced thermodynamic models are quickly adopted. Many of these models are non-cubic...... EoS, such as the PC-SAFT EoS. A major reason for the use of the conventional cubic EoS in reservoir simulation is the concern over computation time. Flash computation is the most time consuming part in compositional reservoir simulation, and the extra complexity of the non-cubic EoS may significantly...... increase the time consumption. In addition to this, the non-cubic EoS also needs a C7+ characterization. The main advantage of the non-cubic EoS is that it provides for a more accurate descrition of fluid properties, and it is therefore of interest to investigate the computational aspects of using...

Para se verificar a prevalência, o impacto no funcionamento pessoal e a procura por tratamento do medo de falar em público, foi realizada uma pesquisa com 452 residentes da cidade de São Paulo, Brasil. Trinta e dois porcento dos entrevistados reportaram ansiedade excessiva quando falavam para um grande grupo de pessoas. No total, 13% dos entrevistados relataram que o medo de falar em público resultou em grande interferência em seu trabalho, vida social e educação, ou causou sofrimento acentuado. Esta pesquisa apóia a inclusão de formas graves do medo de falar em público no constructo diagnóstico da fobia social e sugere, também, que essa ansiedade de falar em público pode ter um impacto negativo na vida de muitos indivíduos na comunidade.

  17. Analytic EoS and PTW strength model recommendation for Starck Ta

    Sjue, Sky K. [Los Alamos National Laboratory; Prime, Michael Bruce [Los Alamos National Laboratory

    2016-09-01

    The purpose of this document is to provide an analytic EoS and PTW strength model for Starck Ta that can be consistently used between different platforms and simulations at three labs. This should provide a consistent basis for comparison of the results of calculations, but not the best implementation for matching a wide variety of experimental data. Another version using SESAME tables should follow, which will provide a better physical representation over a broader range of conditions. The data sets available at the time only include one Hopkinson bar at a strain rate of 1800/s; a broader range of high-rate calibration data would be preferred. The resulting fit gives the PTW parameter p = 0. To avoid numerical issues, p = 0:001 has been used in FLAG. The PTW parameters that apply above the maximum strain rate in the data use the values from the original publication.

  18. Hot super-dense compact object with particular EoS

    We show the possibility of existence of a self-gravitating spherically-symmetric equilibrium configuration for a neutral matter with neutron-like density, small mass M ≪ M_{⊙}, and small radius R ≪ R_{⊙}. We incorporate the effects of both the special and general theories of relativity. Such object may be formed in a cosmic cataclysm, perhaps an exotic one. Since the base equations of hydrostatic equilibrium are completed by the equation of state (EoS) for the matter of the object, we offer a novel, interpolating experimental data from high-energy physics, EoS which permits the existence of such compact system of finite radius. This EoS model possesses a critical state characterized by density ρc and temperature Tc. For such an object, we derive a radial distribution for the super-dense matter in "liquid" phase using Tolman-Oppenheimer-Volkoff equations for hydrostatic equilibrium. We demonstrate that a stable configuration is indeed possible (only) for temperatures smaller than the critical one. We derive the mass-radius relation (adjusted for relativistic corrections) for such small (M ≪ M_{⊙}) super-dense compact objects. The results are within the constraints established by both heavy-ion collision experiments and theoretical studies of neutron-rich matter.

    The following utilities developed for HDF-EOS format data dump are of special use for Earth science data for NASA's Earth Observation System (EOS). This poster demonstrates their use and application. The first four tools take HDF-EOS data files as input. HDF-EOS Metadata Dumper - metadmp Metadata dumper extracts metadata from EOS data granules. It operates by simply copying blocks of metadata from the file to the standard output. It does not process the metadata in any way. Since all metadata in EOS granules is encoded in the Object Description Language (ODL), the output of metadmp will be in the form of complete ODL statements. EOS data granules may contain up to three different sets of metadata (Core, Archive, and Structural Metadata). HDF-EOS Contents Dumper - heosls Heosls dumper displays the contents of HDF-EOS files. This utility provides detailed information on the POINT, SWATH, and GRID data sets. in the files. For example: it will list, the Geo-location fields, Data fields and objects. HDF-EOS ASCII Dumper - asciidmp The ASCII dump utility extracts fields from EOS data granules into plain ASCII text. The output from asciidmp should be easily human readable. With minor editing, asciidmp's output can be made ingestible by any application with ASCII import capabilities. HDF-EOS Binary Dumper - bindmp The binary dumper utility dumps HDF-EOS objects in binary format. This is useful for feeding the output of it into existing program, which does not understand HDF, for example: custom software and COTS products. HDF-EOS User Friendly Metadata - UFM The UFM utility tool is useful for viewing ECS metadata. UFM takes an EOSDIS ODL metadata file and produces an HTML report of the metadata for display using a web browser. HDF-EOS METCHECK - METCHECK METCHECK can be invoked from either Unix or Dos environment with a set of command line options that a user might use to direct the tool inputs and output . METCHECK validates the inventory metadata in (.met file) using The

    CERN has been developing and operating EOS as a disk storage solution successfully for over 6 years. The CERN deployment provides 135 PB and stores 1.2 billion replicas distributed over two computer centres. Deployment includes four LHC instances, a shared instance for smaller experiments and since last year an instance for individual user data as well. The user instance represents the backbone of the CERNBOX service for file sharing. New use cases like synchronisation and sharing, the planned migration to reduce AFS usage at CERN and the continuous growth has brought EOS to new challenges. Recent developments include the integration and evaluation of various technologies to do the transition from a single active in-memory namespace to a scale-out implementation distributed over many meta-data servers. The new architecture aims to separate the data from the application logic and user interface code, thus providing flexibility and scalability to the namespace component. Another important goal is to provide EOS as a CERN-wide mounted filesystem with strong authentication making it a single storage repository accessible via various services and front- ends (/eos initiative). This required new developments in the security infrastructure of the EOS FUSE implementation. Furthermore, there were a series of improvements targeting the end-user experience like tighter consistency and latency optimisations. In collaboration with Seagate as Openlab partner, EOS has a complete integration of OpenKinetic object drive cluster as a high-throughput, high-availability, low-cost storage solution. This contribution will discuss these three main development projects and present new performance metrics.

    Full Text Available Environmental exposure to benzene occurs through cigarette smoke, unleaded gasoline and certain types of plastic. Benzene is converted to hematotoxic metabolites by the hepatic phase-I enzyme CYP2E1, and these metabolites are detoxified by the phase-II enzyme NQO1. The genes encoding these enzymes are highly polymorphic and studies of these polymorphisms have shown different pathogenic and prognostic features in various hematological malignancies. The potential role of different cytochrome p450 metabolizing enzymes in the pathogenesis of acute myeloid leukemia (AML in an area of active interest. In this study, we demonstrate aberrant CYP2E1 mRNA over-expression by quantitative real-time polymerase chain reaction in 11 cases of <em>de novoem> AML with inv(16; CBFβ-MYH11. CYP2E1 mRNA levels correlated with <em>CBFβ>-MYH11 em>transcript levels and with bone marrow blast counts in all cases. CYP2E1 over-expression correlated positively with NQO1 mRNA levels (R2 = 0.934, n = 7. By immunohistochemistry, CYP2E1 protein was more frequently expressed in AML with inv(16 compared with other types of AML (<em>p> < 0.001. We obtained serial bone marrow samples from two patients with AML with inv(16 before and after treatment. CYP2E1 mRNA expression levels decreased in parallel with <em>CBFβ>-MYH11 em>transcript levels and blast counts following chemotherapy. In contrast, CYP1A2 transcript levels did not change in either patient. This is the first study to demonstrate concurrent over-expression of CYP2E1 and NQO1 mRNA in AML with inv(16. These findings also suggest that a balance between CYP2E1 and NQO1 may be important in the pathogenesis of AML with inv(16.

    Full Text Available Nas últimas décadas, a utilização de isótopos estáveis em várias áreas de pesquisa vem se destacando, como na análise de fluxos e rotas metabólicas, análise de efeitos de estresses em plantas e, em grande escala, no estudo da matéria orgânica do solo (MOS. Estudos de alterações e dinâmica da MOS usando a variação da abundância natural do 13C requerem mudanças na razão isotópica do C. Quando não existe essa possibilidade, uma das alternativas é enriquecer o material vegetal (planta com 13C, via fixação de 13CO2, de modo que a razão isotópica seja distinta daquela da MOS original. O objetivo deste trabalho foi investigar a magnitude e a homogeneidade do enriquecimento em 13C em diferentes componentes da planta de eucalipto. No processo de marcação, três plantas de eucalipto, com 4 meses de idade, cultivadas em solução nutritiva foram expostas a uma atmosfera enriquecida com 13CO2, em uma câmara de vidro (448 dm³, com temperatura em torno de 24 ºC. A concentração de CO2 e a razão 13C/12C foram monitoradas por um espectrômetro de massa de razão isotópica (IRMS em amostras de ar retiradas ao longo do processo (126 dias com três pulsos de 13CO2 semanais. Após o período de marcação, as plantas foram separadas em folha (folha-fonte e folha-dreno, galho, casca, lenho e raiz e analisadas em IRMS. O resultado foi expresso em partes por mil (‰ em relação ao padrão internacional de C denominado Pee-Dee Belemnite (PDB, obtendo-se a δ13C PDB delas: folha-fonte (828,07 ‰, folha-dreno (645,72 ‰, galho (672,49 ‰, casca (691,86 ‰, lenho (632,02 ‰ e raiz (536,55 ‰. O padrão de alocação e enriquecimento de 13C entre os componentes das plantas foi homogêneo, embora com diferenças numéricas da ordem de 291 ‰ na δ13C PDB. As plantas de eucalipto mantiveram alta taxa de absorção de CO2 e, consequentemente, alta taxa fotossintética em concentrações de CO2 muito acima (180,4 mmol L-1 - 7

    Aim. Compare EoE-AP with EoE-D for clinical, endoscopy (EGD), histology and outcomes and also with FAP-N. Method. Symptoms, physical findings, EGD, histology, symptom scores, and treatments were recorded for the three groups. Cluster analysis was done. Results. Dysphagia and abdominal pain were different in numbers but not statistically significant between EoE-AP and EoE-D. EGD, linear furrows, white exudates were more in the EoE-D and both combined were significant (p < 0.05). EoE-D, peak and mean eosinophils (p  0.06) and eosinophilic micro abscesses (p  0.001) were higher. Follow-Up. Based on single symptom, EoE-AP had 30% (p  0.25) improvement, EoE-D 86% (p < 0.001) and similar with composite score (p  0.57 and <0.001, resp.). Patients who had follow-up, EGD: 42.8% with EoE-AP and 77.8% with EoE-D, showed single symptom improvement and the eosinophil count fell from 38.5/34.6 (peak and mean) to 31.2/30.4 (p  0.70) and from 43.6/40.8 to 25.2/22.8 (p < 0.001), respectively. FAP-N patients had similar symptom improvement like EoE-D. Cluster Analysis. EoE-AP and FAP-N were similar in clinical features and response to treatment, but EoE-D was distinctly different from EoE-AP and FAP-N. Conclusion. Our study demonstrates that EoE-AP and EoE-D have different histology and outcomes. In addition, EoE-AP has clinical features similar to the FAP-N group.

  10. Probing a steep EoS for dark energy with latest observations

    Science.gov (United States)

    Jaber, Mariana; Macorra, Axel de la

    2018-01-01

    We present a parametrization for the Dark Energy Equation of State "EoS" which has a rich structure, performing a transition at pivotal redshift zT between the present day value w0 to an early time wi =wa +w0 ≡ w(z ≫ 0) with a steepness given in terms of q parameter. The proposed parametrization is w =w0 +wa(z /zT) q /(1 +(z /zT)) q , with w0, wi, q and zT constant parameters. It reduces to the widely used EoS w =w0 +wa(1 - a) for zT = q = 1 . This transition is motivated by scalar field dynamics such as for example quintessence models. We study if a late time transition is favored by BAO measurements combined with local determination of H0 and information from the CMB. We find that our dynamical DE model allows to simultaneously fit H0 from local determinations and Planck CMB measurements, alleviating the tension obtained in a ΛCDM model. We obtain a smaller χ2 in our DE model than in ΛCDM showing that a dynamical DE is preferred with a reduction of 4.8%, 20.2% and 42.8% using BAO + H0, BAO + CMB and BAO + CMB + H0 datasets, respectively. However due to the increased number of free parameters in the EoS information criteria favors ΛCDM over our DE model at this stage. Nevertheless it is crucial to obtain the dynamics of DE from the observational data to show the path for theoretical DE models based on fundamental physics.

    Full Text Available Conventional cytogenetic studies on a female infant with sporadic aniridia revealed what appeared to be a balanced de novo t(11;13 (p13;q33 translocation. Fluorescence in situ hybridization (FISH investigations, however, detected the presence of a cryptic 11p13p14 deletion which included the WAGR region and involved approximately 7.5 Mb of DNA, including the PAX6 and WT1 genes. These results account for the patient's aniridia, and place her at high risk for developing Wilms' tumour. The absence of mental retardation in the patient suggests that the position of the distal breakpoint may also help to refine the mental retardation locus in the WAGR contiguous gene syndrome (Wilms', aniridia, genital anomalies and mental retardation.O estudo citogenético convencional em uma menina com aniridia esporádica resultou em uma aparente translocação balanceada t(11;13(p13;q33 de novo. Entretanto, o estudo citogenético pela hibridação in situ fluorescente (FISH detectou a presença de uma deleção críptica 11p13p14, incluindo a região WAGR e envolvendo aproximadamente 7.5 Mb de DNA, deletando os genes PAX6 e WT1. Estes resultados correlacionam-se com o quadro clínico da paciente e a coloca em alto risco de desenvolver tumor de Wilms. A ausência de retardo mental na paciente indica que a posição distal do ponto de quebra poderá refinar o mapeamento do locus retardo mental na síndrome de genes contíguos WAGR (Wilms, aniridia, anomalias genitais e retardo mental.

    Full Text Available RESUMO Conversões da cobertura vegetal decorrentes do manejo podem alterar o estoque de carbono e a abundância natural de 13C. Objetivou-se avaliar o estoque de C e a abundância natural de 13C em áreas de sucessão de floresta (F e pastagem (P, com diferentes tempos de uso, na Floresta Atlântica no Estado de Santa Catarina. Sete sucessões de uso entre F e P foram definidas por fotografias aéreas tomadas em 1957, 1978 e 2008, entrevistas com moradores e escolha de áreas com florestas em estádio médio de regeneração. As sucessões foram identificadas como FFP, FPF, FFP, FPP, PFF, PPF, PPP, em que a primeira letra se refere ao uso observado em 1957; a segunda, em 1978; e a terceira, em 2008. Foram coletadas amostras de solo nas camadas de 0,00-0,10; 0,10-0,20; 0,20-0,30; 0,30-0,40; 0,40-0,50; 0,50-0,60; 0,60-0,80 e 0,80-1,00 m. Quantificaram-se os teores de carbono orgânico total (COT, abundância de C (δ13C, densidade do solo (Ds e estoque de carbono (ECOT. A conversão de F em P proporcionou aumento da Ds e reduções nos teores de COT e no ECOT do solo. O maior valor de ECOT ocorreu nas áreas atualmente ocupadas por florestas, mesmo tendo sido utilizadas como pasto anteriormente. Áreas de floresta secundária tenderam, em relação aos teores de COT, a um novo equilíbrio, dado que foram verificados teores de COT superiores aos quantificados em áreas de floresta primária. As áreas de floresta e pastagem, com diferentes idades de uso e nas diferentes profundidades de solo avaliadas, evidenciaram respostas na δ13C, resultando em diferentes assinaturas isotópicas, confirmando a mudança de uso de plantas C3 para C4. Em pastagens com 50 anos de uso, na camada de 0,00-0,10 m, 66 % do COT do solo ainda é derivado da floresta original. A análise de componentes principais (ACP indicou que o COT foi o atributo que melhor discriminou as alterações em razão do uso da terra, nas diferentes camadas de solo.

    Thermodynamic and opacity properties of materials are necessary to accurately simulate laser-driven laboratory experiments. Such data are compiled in tabular format since the thermodynamic range that needs to be covered cannot be described with one single theoretical model. Moreover, tabulated data can be made available prior to runtime, reducing both compute cost and code complexity. This approach is employed by the FLASH code. Equation of state (EoS) and opacity data comes in various formats, matrix-layouts, and file-structures. We discuss recent developments on opacplot2, an open-source Python module that manipulates tabulated EoS and opacity data. We present software that builds upon opacplot2 and enables easy-to-use conversion of different table formats into the IONMIX format, the native tabular input used by FLASH. Our work enables FLASH users to take advantage of a wider range of accurate EoS and opacity tables in simulating HELP experiments at the National Laser User Facilities.

  15. Breaking the EOS-gravity degeneracy with masses and pulsating frequencies of neutron stars

    A thorough understanding of many astrophysical phenomena associated with compact objects requires reliable knowledge about both the equation of state (EOS) of super-dense nuclear matter and the theory of strong-field gravity simultaneously because of the EOS-gravity degeneracy. Currently, variations of the neutron star (NS) mass–radius correlation from using alternative gravity theories are much larger than those from changing the NS matter EOS within known constraints. At least two independent observables are required to break the EOS-gravity degeneracy. Using model EOSs for hybrid stars and a Yukawa-type non-Newtonian gravity, we investigate both the mass–radius correlation and pulsating frequencies of NSs. While the maximum mass of NSs increases, the frequencies of the f, p 1 , p 2 , and w I pulsating modes are found to decrease with the increasing strength of the Yukawa-type non-Newtonian gravity, providing a useful reference for future determination simultaneously of both the strong-field gravity and the supranuclear EOS by combining data of x-ray and gravitational wave emissions of NSs.

    A new Sesame EOS table for Ta has been released for testing. It is a limited range table covering T ≤ 26, 000 K and ρ ≤ 37.53 g/cc. The EOS is based on earlier analysis using DFT phonon calculations to infer the cold pressure from the Hugoniot. The cold curve has been extended into compression using new DFT calculations. The present EOS covers expansion into the gas phase. It is a multi-phase EOS with distinct liquid and solid phases. A cold shear modulus table (431) is included. This is based on an analytic interpolation of DFT calculations.

    Capsules P13R and P13S were the seventh and eighth in a series of irradiation tests conducted under the ERDA-sponsored HTGR Fuels and Core Development Program. Reference type LHTGR fuel fabricated with a broad spectrum of property and process variables was irradiated to extreme temperature and fluence conditions. Postirradiation examination revealed that the bonded fuel rods exhibited good stability after irradiation to fast neutron fluences of 12.4 x 10 21 n/cm 2 (E greater than 0.18 MeV), which is 55 percent beyond the LHTGR peak design fast neutron fluence of 8.0 x 10 21 n/cm 2 . Thermal cycling to high temperatures did not adversely affect fuel rod integrity. Particle batches with coating designs representative of the design requirements envisioned for the LHTGR exhibited excellent irradiation performance. Ten batches of fissile and fertile particles were irradiated without coating failure to fast neutron exposures which exceeded the LHTGR peak design exposure by 35 to 52 percent. Capsules P13R and P13S were considered to be very successful qualification tests of LHTGR fuel components. These results provided a substantial data base for the LHTGR Fuel Product Specification and Performance Models used in HTGR core design studies, and demonstrated the excellent irradiation performance of reference LHTGR fuel to well beyond peak design exposures

    Dynamics and direct $CP$ violation in three-body charmless decays of charged $B$ mesons to a proton, an antiproton and a light meson (pion or kaon) are studied using data, corresponding to an integrated luminosity of 1.0$ {\\,fb}^{-1}$, collected by the ${LHCb}$ experiment in $pp$ collisions at a center-of-mass energy of 7 TeV. Production spectra are determined as a function of Dalitz-plot and helicity variables. The forward-backward asymmetry of the light meson in the $p\\bar p$ rest frame is measured. No significant $CP$ asymmetry in $B^+ \\to p \\bar p K^+$ decay is found in any region of the Dalitz plane. We present the first observation of the decay $B^+ \\to \\kern 0.1em\\bar{\\kern -0.1em\\Lambda}(1520)(\\to K^+\\bar p)p$ near the $K^+\\bar p$ threshold and measure $\\mathcal{B}(B^+ \\to \\kern 0.1em\\bar{\\kern -0.1em\\Lambda}(1520)p)=(3.9^{+1.0}_{-0.9} (\\mathrm{stat})\\pm0.1 (\\mathrm{syst})\\pm0.3 (\\mathrm{BF}))\\times 10^{-7}$, where BF denotes the uncertainty on secondary branching fractions.

    A high statistics sample of Λ's produced in 2 GeV/nucleon 5 8Ni + nat Cu collisions has been obtained with the EOS Time Projection Chamber at the Bevalac. The coverage of the EOS TPC is essentially 100% for y > y cm and extends down to P T = 0 where interesting effects such as collective radial expansion may be important. In addition, the detection of a majority of the charged particles in the TPC, along with the presence of directed flow for protons and heavier fragments at this beam energy, allows for the correlation of A production with respect to the event reaction plane. Our preliminary analysis indicates the first observation of a sidewards flow signature for A's. Comparisons with the cascade code ARC are made

    The present study replicates and extends previous research on teaching "How?" mands for information to children with autism. The experimental preparation involved mand training in the context of completing preferred activities and included training and testing under conditions when the establishing operation (EO) was present and absent. Results show that two children with autism acquired mands for information using How? only in situations where information was valuable (i.e., the EO was present); they then consistently made use of the information provided in activity completion. Generalization to novel, untaught situations was assessed.

Todos os BTEX apresentaram expressivo aumento das taxas de volatilização na coluna contendo a mistura gasolina/etanol. Porém, em termos percentuais, o maior e menor aumento nas taxas de volatilização foi observado para tolueno e benzeno, respectivamente. Em amostras de controle, com o percentual de etanol variando entre 0 e 25%, não foi observado aumento no grau de volatilização do etilbenzeno, enquanto que o grau de volatilização dos xilenos foi reduzido. Estes resultados sugerem que, além de forças de interação intermoleculares, efeitos de interação líquido/estrutura do solo podem estar exercendo importante papel na volatilização dos BTEX.The main objective of this paper was the quantitative evaluation of the ethanol's influence about the volatilization of BTEX (benzene, toluene, ethylbenzene and xylenes in a mixture of gasoline and anhydrous ethanol 25% (v/v in experimental columns that simulated soil contamination with gasoline/ethanol. All the BTEX presented expressive increase of volatilization rates in the gasoline-ethanol column. However, in terms of percentage, the highest and lowest volatilization grades were observed for toluene and benzene, respectively. In batch tests (control samples, with mixtures of gasoline ethanol with 0 and 25% (v/v in ethanol, no increase of the volatilization grade was observed for ethylbenzene and the volatilization grade for xylenes was reduced. Matrix effects seem to be, besides the intermolecular interaction forces, important contributions for the volatilization grade of BTEX in this kind of sample.

    Highlights: • Applying sPC-SAFT for phase equilibrium calculations. • Determining Kihara potential parameters for hydrate formers. • Successful usage of the model for systems with hydrate azeotropes. - Abstract: In this communication, equilibrium conditions of clathrate hydrates containing mixtures of noble gases (Argon, Krypton and Xenon) and light hydrocarbons (C 1 –C 3 ), which form structure I and II, are modeled. The thermodynamic model is based on the solid solution theory of Van der Waals–Platteeuw combined with the simplified Perturbed-Chain Statistical Association Fluid Theory equation of state (sPC-SAFT EoS). In dispersion term of sPC-SAFT EoS, the temperature dependent binary interaction parameters (k ij ) are adjusted; taking advantage of the well described (vapor + liquid) phase equilibria. Furthermore, the Kihara potential parameters are optimized based on the P–T data of pure hydrate former. Subsequently, these obtained parameters are used to predict the binary gas hydrate dissociation conditions. The equilibrium conditions of the binary gas hydrates predicted by this model agree well with experimental data (overall AAD P ∼ 2.17)

    Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. We aim to increase the number of asteroid shape models and rotation states within the Eos collision family, as well as to revise previously published shape models from the literature. Such results can be used to constrain theoretical collisional and evolution models of the family, or to estimate other physical parameters by a thermophysical modeling of the thermal infrared data. We use all available disk-integrated optical data (i.e., classical dense-in-time photometry obtained from public databases and through a large collaboration network as well as sparse-in-time individual measurements from a few sky surveys) as input for the convex inversion method, and derive 3D shape models of asteroids together with their rotation periods and orientations of rotation axes. We present updated shape models for 15 asteroids and new shape model determinations for 16 asteroids. Together with the already published models from the publicly available DAMIT database, we compiled a sample of 56 Eos family members with known shape models that we used in our analysis of physical properties within the family. Rotation states of asteroids smaller than ∼ 20 km are heavily influenced by the YORP effect, whilst the large objects more or less retained their rotation state properties since the family creation. Moreover, we also present a shape model and bulk density of asteroid (423) Diotima, an interloper in the Eos family, based on the disk-resolved data obtained by the Near InfraRed Camera (Nirc2) mounted on the W.M. Keck II telescope.

  9. Scaling the EOS namespace

    2017-01-01

    EOS is the distributed storage system being developed at CERN with the aim of fulfilling a wide range of data storage needs, ranging from physics data to user home directories. Being in production since 2011, EOS currently manages around 224 petabytes of disk space and 1.4 billion files across several instances. Even though individual EOS instances routinely manage hundreds of disk servers, users access the contents through a single, unified namespace which is exposed by the head node (MGM), and contains the metadata of all files stored on that instance. The legacy implementation keeps the entire namespace in-memory. Modifications are appended to a persistent, on-disk changelog; this way, the in-memory contents can be reconstructed after every reboot by replaying the changelog. While this solution has proven reliable and effective, we are quickly approaching the limits of its scalability. In this paper, we present our new implementation which is currently in testing. We have designed and implemented QuarkD...

    AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder (EoGD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis (EoE), subepithelial eosinophilic esophagitis (sEoE) and eosinophilic esophageal myositis (EoEM), identified by endoscopy, manometry and serum immunoglobulin E levels (s-IgE), in combination with histological and polymerase chain reaction analyses on esophageal tissue samples. RESULTS In five patients with EoE, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with sEoE and four with EoEM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with EoE and sEoE with some variation, while EoEM was associated with hypercontractile or hypertensive peristalsis, with elevated s-IgE. Histology revealed the following eosinophils per high-power field values. EoE = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; sEoE = 3 in the epithelium and 35 in the subepithelium (conventional biopsy); EoEM = none in the epithelium, 10.7 ± 11.7 in the subepithelium (conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria (peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to EoE. Eotaxin-3, IL-5 and IL-13 were overexpressed in EoE. CONCLUSION Based on clinical and histological data, we identified criteria, which differentiated between EoE, sEoE and EoEM, and reflected a different pathogenesis between these esophageal EoGDs.

    Full Text Available The elliptic-flow ratio of neutrons with respect to protons in reactions of neutron rich Heavy-Ion at intermediate energies has been recently proposed as an observable sensitive to the strength of the symmetry term in the nuclear equation of state (EOS at supra-saturation densities. The recent results obtained from the existing FOPI/LAND data for 197Au+197Au collisions at 400 MeV/nucleon in comparison with the UrQMD model allowed a first estimate of the symmetry term of the EOS but suffer from a considerable statistical uncertainty. In order to obtain an improved data set for Au+Au collisions and to extend the study to other systems, a new experiment was carried out at the GSI laboratory by the ASY-EOS collaboration in May 2011.

    Full Text Available Os mecanismos que controlam o processo de colonização intrarradicular por fungos micorrízicos arbusculares ainda não são conhecidos, mas podem envolver o sistema de defesa vegetal. Normalmente, em condições favoráveis à formação de micorrizas arbusculares (MAs, e.g. baixo fosfato (P, ocorre supressão da expressão de genes de defesa, como quitinases e b-1,3-glucanases, em certos estágios do desenvolvimento das simbioses. Assim, a inibição do crescimento fúngico intrarradicular em condições de alto P pode ser decorrência da atenuação da supressão e/ou indução de genes de defesa específicos. Se o sistema de defesa está envolvido no controle do crescimento fúngico intrarradicular em condições de alto P, a aplicação às raízes de um indutor de respostas de defesa, como o ácido salicílico (AS, poderia simular o efeito inibitório do P. Este trabalho teve por objetivo avaliar o efeito do AS na colonização intrarradicular e nas atividades de quitinases e b-1,3-glucanases em raízes de feijoeiro (Phaseolus vulgaris L. var. Carioca 80-SH inoculadas com Glomus clarum ou Glomus intraradices, em condições de baixo e alto P. Em condições de baixo P, a aplicação de AS inibiu a colonização intrarradicular a níveis similares aos observados em condições de alto P. Em condições de alto P, a inibição da micorrização pelo AS foi ainda maior. Associado a essa inibição, incrementos de aproximadamente 10 vezes nas atividades específicas de quitinases e redução nas atividades de b-1,3-glucanases nas raízes das plantas que receberam AS foram observados. Em função dos padrões de atividades de quitinases e b-1,3-glucanases nas raízes não-inoculadas e inoculadas, não foi possível estabelecer uma relação entre as atividades dessas hidrolases e o crescimento fúngico intrarradicular.

    Subari, M. D.; Hassan, A.

    2014-06-01

    Earth observation satellite (EOS) is currently a major tool to monitor earth dynamics and increase human understanding of earth surface process. Since the early 80s, Malaysia has been using EOS images for various applications, such as weather forecasting, land use mapping, agriculture, environment monitoring and others. Until now, all EOS images were obtained from foreign satellite systems. Realising on the strategic need of having its own capability, Malaysia embarked into EOS development programs in the early 90s. Starting with TiungSAT-1, a micro-satellite carrying small camera, then followed by RazakSAT, a small satellite carrying 2.5 m panchromatic (PAN) medium-aperture-camera, the current satellite program development, the RazakSAT-2, designed to carry a 1.0 m high resolution PAN and 4.0m multi-spectral camera, would become a strategic initiative of the government in developing and accelerating the nation's capability in the area of satellite technology and its application. Would this effort continue until all needs of the remote sensing community being fulfilled by its own EOS? This paper will analyze the intention of the Malaysian government through its National Space Policy and other related policy documents, and proposes some policy options on this. Key factors to be considered are specific data need of the EOS community, data availability and the more subjective political motivations such as national pride.

    The Earth Observing System (EOS), which is part of the International Mission to Planet Earth, is NASA's main contribution to the Global Change Research Program which opens a new era in international cooperation to study the Earth's environment. Five large platforms are to be launched into polar orbit, two by NASA, two by ESA, and one by the Japanese. In such an orbit the radiation resistance of indium phosphide solar cells combined with the potential of utilizing five micron cell structures yields an increase of 10 percent in the payload capability. If further combined with the advanced photovoltaic solar array the payload savings approaches 12 percent.

    The pelvic x-ray is essential for the orthopedic practise. Recently, EOS system has been developed with technology to limit irradiation and theoretically not create magnification. The objective of this study was to evaluate the EOS system realizing a pelvic x-ray. All patients who underwent hip replacement between September 2014 and April 2015 have benefited pelvis radiograph with the 2 techniques, after surgery. The size of the head was measured with both techniques and compared to the established size. Irradiation of each technique was listed. A correlation study was carried out with the body mass index (BMI) of the patient. Irradiation was significantly greater with conventional radiography than with the EOS system: PDS of conventional radiography = 15.0 (10.5; 25.2) against the EOS system PDS = 8.2 (7.1; 9.7), p ≤0.0001. It was found a significant correlation between BMI and irradiation, particularly with conventional radiography. About expansion, the EOS system not create any except in 4 cases, unlike the conventional radiograph. The EOS system significantly decreases irradiation in all patients, compared to the conventional radiography, and it do not create magnification when realizing a pelvic x-ray, even in overweight patients [fr

    NASA's Earth Observing System (EOS) Data and Information System (EOSDIS) program has been processing, archiving, and distributing EOS data since the launch of Terra platform in 1999. The EOSDIS Distributed Active Archive Centers (DAACs) and Science-Investigator-led Processing Systems (SIPSs) are generating over 5000 unique products with a daily average volume of 1.7 Petabytes. Initially EOSDIS had requirements to make process data products within 24 hours of receiving all inputs needed for generating them. Thus, generally, the latency would be slightly over 24 and 48 hours after satellite data acquisition, respectively, for Level 1 and Level 2 products. Due to budgetary constraints these requirements were relaxed, with the requirement being to avoid a growing backlog of unprocessed data. However, the data providers have been generating these products in as timely a manner as possible. The reduction in costs of computing hardware has helped considerably. It is of interest to analyze the actual latencies achieved over the past several years in processing and inserting the data products into the EOSDIS archives for the users to support various scientific studies such as land processes, oceanography, hydrology, atmospheric science, cryospheric science, etc. The instrument science teams have continuously evaluated the data products since the launches of EOS satellites and improved the science algorithms to provide high quality products. Data providers have periodically reprocessed the previously acquired data with these improved algorithms. The reprocessing campaigns run for an extended time period in parallel with forward processing, since all data starting from the beginning of the mission need to be reprocessed. Each reprocessing activity involves more data than the previous reprocessing. The historical record of the reprocessing times would be of interest to future missions, especially those involving large volumes of data and/or computational loads due to

    2017-10-01

    EOS, the CERN open-source distributed disk storage system, provides the highperformance storage solution for HEP analysis and the back-end for various work-flows. Recently EOS became the back-end of CERNBox, the cloud synchronisation service for CERN users. EOS can be used to take advantage of wide-area distributed installations: for the last few years CERN EOS uses a common deployment across two computer centres (Geneva-Meyrin and Budapest-Wigner) about 1,000 km apart (∼20-ms latency) with about 200 PB of disk (JBOD). In late 2015, the CERN-IT Storage group and AARNET (Australia) set-up a challenging R&D project: a single EOS instance between CERN and AARNET with more than 300ms latency (16,500 km apart). This paper will report about the success in deploy and run a distributed storage system between Europe (Geneva, Budapest), Australia (Melbourne) and later in Asia (ASGC Taipei), allowing different type of data placement and data access across these four sites.

  5. EOS7R: Radionuclide transport for TOUGH2

    International Nuclear Information System (INIS)

    Oldenburg, C.M.; Pruess, K.

    1995-11-01

    EOS7R provides radionuclide transport capability for TOUGH2. EOS7R extends the EOS7 module (water, brine, and optional air) to model water, brine, parent component, daughter component, and optional air and heat. The radionuclide components follow a first-order decay law, and may adsorb onto the solid grains. Volatilization of the decaying components is modeled by Henry's Law. The decaying components are normally referred to as radionuclides, but they may in fact by any trace components that decay, adsorb, and volatilize. The decay process need not be radioactive decay, but could be any process that follows a first-order decay law, such as biodegradation. EOS7R includes molecular diffusion for all components in gaseous and aqueous phases using a simplified binary diffusion model. When EOS7R is used with standard TOUGH2, transport occurs by advection and molecular diffusion in all phases. When EOS7R is coupled with the dispersion module T2DM, one obtains T2DMR, the radionuclide transport version of T2DM. T2DMR models advection, diffusion, and hydrodynamic dispersion in rectangular two-dimensional regions. Modeling of radionuclide transport requires input parameters specifying the half-life for first-order decay, distribution coefficients for each rock type for adsorption, and inverse Henry's constants for volatilization. Options can be specified in the input file to model decay in inactive grid blocks and to read from standard EOS7 INCON files. The authors present a number of example problems to demonstrate application and accuracy of TOUGH2/EOS7R. One-dimensional simulation results agree well with analytical solutions. For a two-dimensional salt-dome flow problem, the final distribution of daughter radionuclide component is complicated by the presence of weak recirculation caused by density effects due to salinity

    2017-01-01

    Accurate description of thermodynamic properties of natural gas systems is of great significance in the oil and gas industry. For this application, non-cubic equations of state (EoSs) are advantageous due to their better density and compressibility description. Among the non-cubic models, GERG-2008...... is a new wide-range EoS for natural gases and other mixtures of 21 natural gas components. It is considered as a standard reference equation suitable for natural gas applications where highly accurate thermodynamic properties are required. Soave's modification of Benedict-Webb-Rubin (Soave-BWR) Eo......S is another model that despite its empirical nature, provides accurate density description even around the critical point. It is much simpler than GERG-2008 and easier to handle and generalize to reservoir oil fluids. This study presents a comprehensive comparison between GERG-2008 and other cubic (SRK and PR...

    Full Text Available Abstract In Italy there are two species of <em>Apodemus> (<em>Sylvaemus>: <em>Apodemus sylvaticusem> on the mainland and the main island, and <em>Apodemus flavicollisem> only on the mainland. The trend of some morphometric characters of the skull (incisive foramen length - FI; interorbital breadth = IO; length of palatal bridge = PP; upper alveolar length = $M^1M^3$ was analized and some theoretical models verified for <em>A. sylvaticusem>. If one considers the sympatric population of <em>A. sylvaticusem> and <em>A. flavicollisem> simultaneously the characters PP, IO and $M^1M^3$ appear significantly isometric being directly correlated ($P leq O.O1$, while FI character results allometric with respect to the previous ones, as expected. If one considers the sympatric populations of each of the species separately, the scenario is different. For <em>A. sylvaticusem> only PP and $M^1M^3$ are isometric ($P leq 0.05$. For <em>A. flavicollisem> only $M^1M^3$ and FI appear to be correlated, although not as significantly as for <em>A. sylvaticusem> ($P le 0.05$; one tail. The insular populations of <em>A. sylvaticusem> do not show significant correlations, except for FI and $M^1M^3$ ($P le 0.05$. On the contrary, considering all populations, sympatric and allopatric, of <em>A. sylvaticusem> at the same time are significant correlations ($P le 0.05$ in all combinations of characters, except for those involving the IO. We suggest that the isometric relations in sympatric assemblages are confined within a morphological range available to the genus <em>Apodemus>. In such a space, the two species are split in two different and innerly homogeneous distributions. We found no evidence to confirm the niche variation hypothesis. On the contrary, the variability expressed as SO or CV's appears higher in the sympatric populations than in the allopatric ones, for three of the four characters, confirming previous results

    Serial casting has demonstrated efficacy for idiopathic early-onset scoliosis (EOS). Results of casting in nonidiopathic (syndromic and congenital) EOS patients have not previously been well described. A total of 53 patients underwent serial casting for EOS from 2005 to 2010 at a single institution. Deformity was classified as idiopathic or nonidiopathic. Diagnosis, time in cast, number of casts, use of bracing, complications, and outcomes were recorded. Radiographic measures included Cobb angle and thoracic height (T1-T12). Thoracic height velocity was calculated and compared with established norms. A total of 36 patients, 19 idiopathic and 17 nonidiopathic (14 syndromic, 3 congenital), completed cast treatment and had >6-month follow-up and were therefore included. Of those, 17% (6/36) experienced resolution of their deformity, 53% (19/26) are currently in braces, and 31% (11/36) had undergone surgery. Surgery occurred on average at age 5.6 years and was delayed by an average of 2.1 years from time of first cast. A 19% complication was observed. There was no statistical difference in the rate of resolution of deformity between idiopathic (5/19) and nonidiopathic (1/17) patients (P=0.182), although there exists a trend toward greater curve correction in idiopathic patients. Surgery occurred in fewer patients (2/19) in the idiopathic group compared with the nonidiopathic group (9/17) (P=0.006). Significant improvements in Cobb angle was observed in the idiopathic group (12.2 degrees) during casting (P=0.003). Nonidiopathic patients did not maintain the correction gained during casting at the time of final follow-up. T1-T12 height increased across all study patients regardless of etiology during the period of casting at similar velocity to established norms of 1.4 cm/y for this age group. Serial casting offers modest deformity correction in idiopathic deformities compared with nonidiopathic deformities. Thoracic height growth continued throughout the casting period

    1998-07-01

    A database has been created for use with the Jacobs-Cowperthwaite-Zwisler-3 equation-of-state (JCZ3-EOS) to determine thermochemical equilibrium for detonation and expansion states of energetic materials. The JCZ3-EOS uses the exponential 6 intermolecular potential function to describe interactions between molecules. All product species are characterized by r*, the radius of the minimum pair potential energy, and {var_epsilon}/k, the well depth energy normalized by Boltzmann`s constant. These parameters constitute the JCZS (S for Sandia) EOS database describing 750 gases (including all the gases in the JANNAF tables), and have been obtained by using Lennard-Jones potential parameters, a corresponding states theory, pure liquid shock Hugoniot data, and fit values using an empirical EOS. This database can be used with the CHEETAH 1.40 or CHEETAH 2.0 interface to the TIGER computer program that predicts the equilibrium state of gas- and condensed-phase product species. The large JCZS-EOS database permits intermolecular potential based equilibrium calculations of energetic materials with complex elemental composition.

  11. Building EOS capability for Malaysia – the options

    2014-01-01

    Earth observation satellite (EOS) is currently a major tool to monitor earth dynamics and increase human understanding of earth surface process. Since the early 80s, Malaysia has been using EOS images for various applications, such as weather forecasting, land use mapping, agriculture, environment monitoring and others. Until now, all EOS images were obtained from foreign satellite systems. Realising on the strategic need of having its own capability, Malaysia embarked into EOS development programs in the early 90s. Starting with TiungSAT-1, a micro-satellite carrying small camera, then followed by RazakSAT, a small satellite carrying 2.5 m panchromatic (PAN) medium-aperture-camera, the current satellite program development, the RazakSAT-2, designed to carry a 1.0 m high resolution PAN and 4.0m multi-spectral camera, would become a strategic initiative of the government in developing and accelerating the nation's capability in the area of satellite technology and its application. Would this effort continue until all needs of the remote sensing community being fulfilled by its own EOS? This paper will analyze the intention of the Malaysian government through its National Space Policy and other related policy documents, and proposes some policy options on this. Key factors to be considered are specific data need of the EOS community, data availability and the more subjective political motivations such as national pride

    Objectives: To demonstrate the reliability of the EOS imaging system in measuring the internal diameters of the bony pelvis. Materials and methods: A prospective study comparing the results of the pelvimetry of 18 dry pelvises carried out on the EOS imaging system to measurements taken manually and using the two current gold standard CT methods. Pelvi-metric measurements of each pelvic bone were obtained using four methods and compared: direct manual measurements, spiral and sequential CT pelvimetry, and 2D-3D low-dose bi-planar X-rays. The various obstetric diameters were measured to the millimetre and compared. Results: There was no significant difference in the different diameters assessed, with the exception of the inter-spinous diameter. There was a highly significant correlation (P < 0.001) between the values measured manually and by EOS for the Magnin index (Pearson = 0.98), the obstetric conjugate diameter (Pearson = 0.99), and the median transverse diameter (Pearson = 0.87). Conclusion: The EOS imaging system allows for an ex vivo determination of the obstetrical diameters that is reliable enough to estimate obstetric prognosis, producing comparable measurements to CT. In view of concerns about protection from radiation, this low-dose imaging technique could become, after in vivo prospective validation, the new gold standard for pelvimetry and therefore a good alternative to CT.

    17p13.1 Deletion encompassing TP53 has been described as a syndrome characterized by intellectual disability and dysmorphic features. Only one case with a 17p13.1 duplication encompassing TP53 has been reported in a patient with intellectual disability, seizures, obesity, and diabetes mellitus. Here, we present a patient with a 17p13.1 duplication who exhibited obesity and intellectual disability, similar to the previous report. The 9-year-old proposita was referred for the evaluation of intellectual disability and obesity. She also exhibited insulin resistance and liver dysfunction. She had wide palpebral fissures, upturned nostrils, a long mandible, short and slender fingers, and skin hyperpigmentation. Array comparative genomic hybridization (array CGH) detected a 3.2 Mb duplication of 17p13.1-p13.2 encompassing TP53, FXR2, NLGN2, and SLC2A4, which encodes the insulin-responsive glucose transporter 4 (GLUT4) associated with insulin-stimulated glucose uptake in adipocytes and muscle. We suggest that 17p13.1 duplication may represent a clinically recognizable condition characterized partially by a characteristic facial phenotype, developmental delay, and obesity. © 2014 Wiley Periodicals, Inc.

    Widhe, Olle

    2014-12-01

    Full Text Available In the history of Nordic children’s literature the Swedish speaking Finnish author Zacharias Topelius (1818–1898 is not only recognized for developing a new form of realism but also for his fictional rascal, Walter. His eight stories about the mischievous Walter, “Walters Äfwentyr” (1855–1856, originally published in the Finnish magazine Eos, is thus considered to be the first children’s stories in Swedish that articulate the child as an unruly but good-hearted character. This essay, however, shows that the development of Topelian realism, and the emergence of the rascal and villain in the Nordic literature for children during the 1850s, is closely connected to the depiction of children’s play. In many of the stories published in Eos Topelius returns to the portrayal of young boys playing soldiers. In this way he positions the spirited fantasy of children in opposition to the adult world of order and seriousness. This alternative geography of play creates a space for the child’s perspective, and does it in a mode that resembles the realism of the forerunner Olof Fryxell (1806–1900. Topelius’ representation of play nevertheless seems to stand in opposition to the adult world in a more explicit way. It conveys the imaginings of unruly and playful boyhood masculinity as a means to achieve the seriousness of the adult middle-class male.

    1993-01-01

    The National Aeronautics and Space Administration's (NASA) Earth Observing System (EOS) will provide a comprehensive long term set of observations of the Earth to the Earth science research community. The data will aid in determining global changes caused both naturally and through human interaction. Understanding man's impact on the global environment will allow sound policy decisions to be made to protect our future. EOS is a major component of the Mission to Planet Earth program, which is NASA's contribution to the U.S. Global Change Research Program. EOS consists of numerous instruments on multiple spacecraft and a distributed ground system. The EOS Data and Information System (EOSDIS) is the major ground system developed to support EOS. The EOSDIS will provide EOS spacecraft command and control, data processing, product generation, and data archival and distribution services for EOS spacecraft. Data from EOS instruments on other Earth science missions (e.g., Tropical Rainfall Measuring Mission (TRMM)) will also be processed, distributed, and archived in EOSDIS. The U.S. and various International Partners (IP) (e.g., the European Space Agency (ESA), the Ministry of International Trade and Industry (MITI) of Japan, and the Canadian Space Agency (CSA)) participate in and contribute to the international EOS program. The EOSDIS will also archive processed data from other designated NASA Earth science missions (e.g., UARS) that are under the broad umbrella of Mission to Planet Earth.

    The MWA EoR is one of a small handful of experiments designed to detect the statistical signal from the Epoch of Reionisation. Each of these experiments has reached a level of maturity, where the challenges, in particular of foreground removal, are being more fully understood. Over the past decade, the MWA EoR Collaboration has developed expertise and an understanding of the elements of the telescope array, the end-to-end pipelines, ionospheric conditions, and and the foreground emissions. Sufficient data has been collected to detect the theoretically predicted EoR signal. Limits have been published regularly, however we still several orders of magnitude from a possible detection. This paper outlines recent progress and indicates directions for future efforts.

    SenSyF is a cloud-based data processing framework for EO- based services. It has been pioneer in addressing Big Data issues from the Earth Observation point of view, and is a precursor of several of the technologies and methodologies that will be deployed in ESA's Thematic Exploitation Platforms and other related systems.The SenSyF system focuses on developing fully automated data management, together with access to a processing and exploitation framework, including Earth Observation specific tools. SenSyF is both a development and validation platform for data intensive applications using Earth Observation data. With SenSyF, scientific, institutional or commercial institutions developing EO- based applications and services can take advantage of distributed computational and storage resources, tailored for applications dependent on big Earth Observation data, and without resorting to deep infrastructure and technological investments.This paper describes the integration process and the experience gathered from different EO Service providers during the project.

    HAT-P-13 b is a transiting hot Jupiter with a slightly eccentric orbit (e = 0.010) inhabiting a two-planet system. The two-planet arrangement provides an opportunity to probe the interior structure of HAT-P-13b. Under equilibrium-tide theory and confirmation that the apsides of planets b and c are in alignment, a measurement of the planet's eccentricity can be related to the planet's tidal Love number k2, which describes the central condensation of the planet's mass and its deformation under tidal effects. A measurement of k2 could constrain interior models of HAT-P-13b. HAT-P-13b's orbit is configured favorably for refinement of the eccentricity by secondary eclipse timing observations, which provide direct measurements of ecosω. In 2010, Spitzer observed two secondary eclipses of HAT-P-13b in the 3.6- and 4.5-μm IRAC bandpasses. We present secondary eclipse times and depths; joint models of the HAT-P-13 system that incorporate transit photometry and radial velocity data; and constraints on the atmospheric chemistry of HAT-P-13b that suggest solar-abundance composition without a thermal inversion. Spitzer is operated by the Jet Propulsion Laboratory, California Institute of Technology, under a contract with NASA, which provided support for this work. This work was supported in part by NASA Planetary Atmospheres Grant NNX13AF38G.

    Full Text Available Resumo:Sarcoides são tumores fibroblásticos, considerados os tumores de pele mais comuns em pele de equinos e que raramente apresentam regressão espontânea. Papilomavírus bovino (BPV tipos 1 e 2 são relacionados com a patogenia do sarcoide e, provavelmente, o BPV tipo 13 (BPV13, recentemente descrito, também pode estar associado com a formação dessa lesão. Neste estudo, 20 amostras de lesões cutâneas, sendo 12 constituídas por tecidos frescos e 8 amostras de tecido fixado em formalina e embebido em parafina, provenientes de 15 cavalos foram utilizadas para a identificação do DNA de BPV. A análise histopatológica (HE confirmou todas as lesões como sarcoide. Para a amplificação do DNA de papilomavírus (PV foram realizadas três reações de PCR. Como triagem, os primers IFNR2/IDNT2 foram utilizados para amplificar um fragmento da ORF L1 do PV. O segundo par de primersutilizado é complementar a sequência dos genes E5 e L2 de BPVs 1, 2 e 13. O terceiro par de primers(FAP59/FAP64 utilizado tem o gene L1 como alvo. A primeira e a segunda PCRs permitiram amplificar produtos em todas as amostras avaliadas. Entretanto, na terceira reação, na qual foram utilizados os primers FAP, foi possível amplificar produtos com tamanho molecular esperado somente nas amostras constituídas por tecidos frescos. O sequenciamento de nucleotídeos e as análises filogenéticas realizadas nos fragmentos E5L2 resultaram na identificação de BPV1, 2 e 13 em 14 (70%, 2 (10% e em 4 (20% amostras de sarcoides, respectivamente. As amostras de sarcoides de um dos animais continha somente o DNA de BPV1. Entretanto, nas amostras provenientes do segundo cavalo foi possível identificar o DNA de três tipos de Deltapapillomavirus bovino (BPV1, 2 e 13 em lesões distintas. Este estudo ratifica a presença do DNA de BPV1, 2 e 13 em lesões de sarcoides em equinos, além de identificar três tipos de BPVs em um mesmo animal e descrever pela primeira vez no

    Literature in the application of gait training techniques in persons with traumatic brain injury (TBI) is limited. Current techniques require multiple staff and are physically demanding. The use of a robotic locomotor training may provide improved training capacity for this population. To examine the impact of 3 different modes of locomotor therapy on gait velocity and spatiotemporal symmetry using an end effector robot (G-EO); a robotic exoskeleton (Lokomat), and manual assisted partial-body weight-supported treadmill training (PBWSTT) in participants with traumatic brain injury. Randomized, prospective study. Tertiary rehabilitation hospital. A total of 22 individuals with ≥12 months chronic TBI with hemiparetic pattern able to walk overground without assistance at velocities between 0.2 and 0.6 m/s. Eighteen sessions of 45 minutes of assigned locomotor training. Overground walking self-selected velocity (SSV), maximal velocity (MV), spatiotemporal asymmetry ratio, 6-Minute Walk Test (6MWT), and mobility domain of Stroke Impact Scale (MSIS). Severity in walking dysfunction was similar across groups as determined by walking velocity data. At baseline, participants in the Lokomat group had a baseline velocity that was slightly slower compared with the other groups. Training elicited a statistically significant median increase in SSV for all groups compared with pretraining (Lokomat, P = .04; G-EO, P = .03; and PBWSTT, P = .02) and MV excluding the G-EO group (Lokomat, P = .04; PBWSTT, P = .03 and G-EO, P = .15). There were no pre-post significant differences in swing time, stance time, and step length asymmetry ratios at SSV or MV for any of the interventions. Mean rank in the change of SSV and MV was not statistically significantly different between groups. Participants in the G-EO and PBWSTT groups significantly improved their 6MWT posttraining (P = .04 and .03, respectively). The MSIS significantly improved only for the Lokomat group (P = .04 and .03). The

    The house dust mite (HDM) is considered to be the most common indoor allergen associated with bronchial asthma. In this study, we investigated whether crude extract of the HDM Dermatophagoides farinae could activate human eosinophilic leukemic cells (EoL-1) to induce upregulation of cell-surface adhesion molecules. When EoL-1 cells were incubated with D. farinae extract, expression of intercellular adhesion molecule-1 (ICAM-1) significantly increased on the cell surfaces compared to cells incubated with medium alone. In contrast, surface expression of CD11b and CD49d in EoL-1 cells was not affected by D. farinae extract. In addition, pretreatment of cells with NF-kappaB inhibitor (MG-132) or JNK inhibitor (SP600125) significantly inhibited ICAM-1 expression promoted by HDM extract. However, neither p38 MAP kinase inhibitor nor MEK inhibitor prevented HDM-induced ICAM-1 expression in EoL-1 cells. These results suggest that crude extract of D. farinae induces ICAM-1 expression in EoL-1 cells through signaling pathways involving both NF-kappaB and JNK.

  15. Rigorous theoretical constraint on constant negative EoS parameter [Formula: see text] and its effect for the late Universe.

    Science.gov (United States)

    Burgazli, Alvina; Eingorn, Maxim; Zhuk, Alexander

    In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, the Universe is filled with inhomogeneously distributed discrete structures (galaxies, groups and clusters of galaxies). Supposing that the Universe contains also the cosmological constant and a perfect fluid with a negative constant equation of state (EoS) parameter [Formula: see text] (e.g., quintessence, phantom or frustrated network of topological defects), we investigate scalar perturbations of the Friedmann-Robertson-Walker metrics due to inhomogeneities. Our analysis shows that, to be compatible with the theory of scalar perturbations, this perfect fluid, first, should be clustered and, second, should have the EoS parameter [Formula: see text]. In particular, this value corresponds to the frustrated network of cosmic strings. Therefore, the frustrated network of domain walls with [Formula: see text] is ruled out. A perfect fluid with [Formula: see text] neither accelerates nor decelerates the Universe. We also obtain the equation for the nonrelativistic gravitational potential created by a system of inhomogeneities. Due to the perfect fluid with [Formula: see text], the physically reasonable solutions take place for flat, open and closed Universes. This perfect fluid is concentrated around the inhomogeneities and results in screening of the gravitational potential.

  16. Dielectric relaxations and conduction mechanisms in polyether-clay composite polymer electrolytes under high carbon dioxide pressure.

    The composite material P(EO/EM)-Sa consisting of synthetic saponite (Sa) dispersed in poly[ethylene oxide-co-2-(2-methoxyethoxy)ethyl glycidyl ether] (P(EO/EM)) is studied by "in situ" measurements using broadband electrical spectroscopy (BES) under pressurized CO2 to characterize the dynamic behavior of conductivity and the dielectric relaxations of the ion host polymer matrix. It is revealed that there are three dielectric relaxation processes associated with: (I) the dipolar motions in the short oxyethylene side chains of P(EO/EM) (β); and (II) the segmental motion of the main chains comprising the polyether components (αfast, αslow). αslow is attributed to the slow α-relaxation of P(EO/EM) macromolecules, which is hindered by the strong coordination interactions with the ions. Two conduction processes are observed, σDC and σID, which are attributed, respectively, to the bulk conductivity and the interdomain conductivity. The temperature dependence of conductivity and relaxation processes reveals that αfast and αslow are strongly correlated with σDC and σID. The "in situ" BES measurements under pressurized CO2 indicate a fast decrease in σDC at the initial CO2 treatment time resulting from the decrease in the concentration of polyether-M(n+) complexes, which is driven by the CO2 permeation. The relaxation frequency (fR) of αslow at the initial CO2 treatment time increases and shows a steep rise with time with the same behavior of the αfast mode. It is demonstrated that the interactions between polyether chains of P(EO/EM) and cations in the polymer electrolyte layers embedded in Sa are probably weakened by the low permittivity of CO2 (ε = 1.08). Thus, the formation of ion pairs in the polymer electrolyte domains of P(EO/EM)-Sa occurs, with a corresponding reduction in the concentration of ion carriers.

    Benzo[a]pyrene (BaP) has been shown to affect both the development and response of T and B cells in the immune system. However, the effect of BaP on other immune cells, such as eosionophils, is unknown. In this study, we investigated the effect of BaP on the production of vascular endothelial growth factor (VEGF) using an in vitro eosinophilic EoL-1 cell and human umbilical vein endothelial cell (HUVEC) co-culture system. EoL-1-conditioned medium was found to promote the growth of HUVEC in a time-dependent manner. The growth stimulating activity was due to the production of VEGF by the EoL-1 cells. The production of VEGF was correlated with the enhanced expression of the phosphorylated form of extracellular signal-regulated kinases (p-ERKs) and the upregulated expression of VEGF mRNA. Furthermore, BaP-induced expression of VEGF mRNA was reduced by the ERK inhibitor PD98059. Results from this study suggested that BaP might affect the growth of endothelial cells through the modulation of VEGF production by eosinophils.

    MOHID LAND is a open source watershed model developed by MARETEC and is part of the MOHID Framework. It integrates four mediums (or compartments): porous media, surface, rivers and atmosphere. The movement of water between these mediums are based on mass and momentum balance equations. The atmosphere medium is not explicity simulated. Instead, it's used as boundary condition to the model through meteorological properties: precipitation, solar radiation, wind speed/direction, relative humidity and air temperature. The surface medium includes the overland runoff and vegetation growth processes and is simulated using a 2D grid. The porous media includes both the unsaturated (soil) and saturated zones (aquifer) and is simulated using a 3D grid. The river flow is simulated through a 1D drainage network. All these mediums are linked through evapotranspiration and flow exchanges (infiltration, river-soil growndwater flow, surface-river overland flow). Besides the water movement, it is also possible to simulate water quality processes and solute/sediment transport. Model setup include the definition of the geometry and the properties of each one of its compartments. After the setup of the model, the only continuous input data that MOHID LAND requires are the atmosphere properties (boundary conditions) that can be provided as timeseries or spacial data. MOHID LAND has been adapted the last 4 years under FP7 and ESA projects to integrate Earth Observation (EO) data, both variable in time and in space. EO data can be used to calibrate/validate or as input/assimilation data to the model. The currently EO data used include LULC (Land Use Land Cover) maps, LAI (Leaf Area Index) maps, EVTP (Evapotranspiration) maps and SWC (Soil Water Content) maps. Model results are improved by the EO data, but the advantage of this integration is that the model can still run without the EO data. This means that model do not stop due to unavailability of EO data and can run on a forecast mode

    Differences in the initial management of pediatric eosinophilic esophagitis (EoE) by practice setting have not been well characterized. We aimed to characterize these differences for sites in the Carolinas EoE Collaborative (CEoEC), a multicenter network of academic and community practices. We performed a retrospective cohort study of pediatric EoE patients at five CEoEC sites: University of North Carolina (UNC) Hospital, Charlotte Asthma and Allergy Specialists, Greenville Health Systems, Wake Forest Baptist Medical Center, and the Medical University of South Carolina Hospital. Cases of EoE were defined by consensus guidelines. Data were extracted from electronic medical records. We tested for differences among sites and used a multinomial model (polytomous regression) to assess associations between treatment and site, adjusting on patient factors. We identified 464 children with EoE across the CEoEC sites. The median age was highest at Wake Forest (11.4 years), the median eosinophil count was highest at UNC (69 eos/hpf), and UNC had the most male patients (82%). UNC used topical steroids for initial treatment in 86% of cases, compared with <1% in Greenville ( P < 0.01). Greenville used dietary elimination more frequently than UNC (81% vs 2%, P < 0.01). Differences in treatment approach held after adjusting for potential baseline confounders. There was no significant association between patient factors and initial treatment approach. Significant differences in EoE patient factors and treatment approaches were identified across CEoEC sites and were not explained by patient or practice factors. This suggests that institutional or provider preferences drive initial treatment approaches, and that more data are needed to drive best practice decisions.

    2014-04-01

    These proceedings comprise the invited lectures of the second international symposium on Emergent Quantum Mechanics (EmQM13), which was held at the premises of the Austrian Academy of Sciences in Vienna, Austria, 3-6 October 2013. The symposium was held at the ''Theatersaal'' of the Academy of Sciences, and was devoted to the open exploration of emergent quantum mechanics, a possible ''deeper level theory'' that interconnects three fields of knowledge: emergence, the quantum, and information. Could there appear a revised image of physical reality from recognizing new links between emergence, the quantum, and information? Could a novel synthesis pave the way towards a 21st century, ''superclassical'' physics? The symposium provided a forum for discussing (i) important obstacles which need to be overcome as well as (ii) promising developments and research opportunities on the way towards emergent quantum mechanics. Contributions were invited that presented current advances in both standard as well as unconventional approaches to quantum mechanics. The EmQM13 symposium was co-organized by Gerhard Grössing (Austrian Institute for Nonlinear Studies (AINS), Vienna), and by Jan Walleczek (Fetzer Franklin Fund, USA, and Phenoscience Laboratories, Berlin). After a very successful first conference on the same topic in 2011, the new partnership between AINS and the Fetzer Franklin Fund in producing the EmQM13 symposium was able to further expand interest in the promise of emergent quantum mechanics. The symposium consisted of two parts, an opening evening addressing the general public, and the scientific program of the conference proper. The opening evening took place at the Great Ceremonial Hall (Grosser Festsaal) of the Austrian Academy of Sciences, and it presented talks and a panel discussion on ''The Future of Quantum Mechanics'' with three distinguished speakers: Stephen Adler (Princeton), Gerard 't Hooft (Utrecht) and Masanao Ozawa (Nagoya).

  5. Eos and the Youth: A Case of Inverted Roles in Rape

    Science.gov (United States)

    Dipla, Anthi

    This article examines scenes of Eos pursuing/abducting youths on 5th-century Athenian vases. Eos, the personification of Dawn, is the only woman assuming the role of a pursuer in rape. The theme strangely becomes very popular with vase painters to a degree comparable to ephebes pursuing a woman. The iconography of the scenes is systematically analysed and evaluated. All theories explaining the popularity of the theme from its presumable use as a parable for death are considered. Eos is moreover compared to other winged figures in pursuit that are popular in the same period, especially Sphinx and Eros. Conversely, it is illustrated how Eos' pursuits of youths are thoroughly coined on the same model as ephebe rape scenes. These may have been so popular because they expressed prevalent social notions about how women, like animals,would need subduing/taming by the ephebe, future citizen hunters, before they could assume their appropriate place in society. With Eos the hunter becomes the prey of a wild woman, who has transgressed the control limits set by the social system. Eos is promoted as the ultimate model of what a woman should not be.

    Reliable thermodynamic databases for rock forming minerals are essential for petrological and geodynamic studies. While the available databases (1-3) represent laudable efforts, none seems to be completely satisfactory. We show inter-comparison of phase diagrams computed from different databases and also their comparisons with experimental phase diagrams in complex systems. The results show good agreement and also significant disagreements in some P-T-X regimes; resolution of these disagreements via new experimental and thermodynamic data is needed to sort out the problems and make further progress. Two of the main challenges in the development of databases (4) seem to be (a) appropriate formulation of an EoS for solids that is suitable for studies of Earth and planetary interiors and (b) relatively simple formulations of thermodynamic mixing properties of mantle minerals that perform well within the compositional space of interest. While work on EoS formulation continues, we present a semi-empirical numerical approach that creates a consistent set of material properties (α, K, Cp, Cv) up to very high P-T conditions by satisfying certain physical constraints. Adequate experimental data are not available to constrain the mixing properties of several minerals that would be valid over the compositional range of interest in the natural environments. We have, thus, pursued an alternative approach on the basis of physical and crystal-chemical data. It is found that combination of elastic mixing energy, incorporating the effect of multi-atom interactions (5, 6), and crystal-field (CF) energy of mixing provide enthalpy of mixing in binary solid solutions that are in good agreement with experimental and calorimetric data. The CF-splitting vs. composition in a solid solution involving transition metal ion may be approximated by a semi-empirical relation using mean metal-oxygen bond-distance when such data are not available from spectroscopic studies. We also discuss the

    Full Text Available Accurate and fine-grained discovery by diverse Earth observation (EO sensors ensures a comprehensive response to collaborative observation-required emergency tasks. This discovery remains a challenge in an EO sensor web environment. In this study, we propose an EO sensor observation capability metadata model that reuses and extends the existing sensor observation-related metadata standards to enable the accurate and fine-grained discovery of EO sensors. The proposed model is composed of five sub-modules, namely, ObservationBreadth, ObservationDepth, ObservationFrequency, ObservationQuality and ObservationData. The model is applied to different types of EO sensors and is formalized by the Open Geospatial Consortium Sensor Model Language 1.0. The GeosensorQuery prototype retrieves the qualified EO sensors based on the provided geo-event. An actual application to flood emergency observation in the Yangtze River Basin in China is conducted, and the results indicate that sensor inquiry can accurately achieve fine-grained discovery of qualified EO sensors and obtain enriched observation capability information. In summary, the proposed model enables an efficient encoding system that ensures minimum unification to represent the observation capabilities of EO sensors. The model functions as a foundation for the efficient discovery of EO sensors. In addition, the definition and development of this proposed EO sensor observation capability metadata model is a helpful step in extending the Sensor Model Language (SensorML 2.0 Profile for the description of the observation capabilities of EO sensors.

    Family caregivers play an important role in end-of-life (EoL) decision making when the patient is unable to make his/her own decisions. While communication about EoL care between patients and family is perhaps a first step toward advance care planning (ACP)/EoL decisions, not every culture puts great value on open communication about this topic. The aims of the present study were to explore EoL communication and the aspects of communication among caregivers of Latino patients in the rural United States (U.S.)-Mexico border region. This study analyzed data from a hospice needs assessment collected from 189 family caregivers of Latino patients at a home health agency in a rural U.S.-Mexico border region. Bivariate tests and logistic regression were used to address our aims. About half of the family caregivers (n = 96, 50.8%) reported to have ever engaged in EoL discussion with patients. Significant predictors of EoL discussion included life-sustaining treatment preference (odds ratio [OR] = 0.44, p EoL communication. Also, caregivers who worried that physicians might want to stop treatments (i.e., "pull the plug") too soon were less likely to do so. Conversely, caregivers who had knowledge about ADs were more likely to engage in EoL communication. EoL communication is a complex process influenced by individual, social, and cultural values and the beliefs of both the patient and his/her family. Inclusion of family caregivers in the ACP process and facilitating culturally tailored EoL communication between patients and family caregivers is important.

    Full Text Available RESUMO: O tramadol é um fármaco opioide amplamente utilizado em medicina veterinária, porém seu uso e eficácia analgésica pós-cirúrgica não foi investigado em aves. Objetivou-se avaliar a eficácia do tramadol ou butorfanol em galos submetidos à ostessíntese de úmero. Foram utilizados 12 galos (Gallus gallus domesticus, os quais foram alocados aleatoriamente em dois grupos: grupo tramadol (GT que recebeu como medicação pré anestésica (MPA 5mg.Kg-1 de tramadol e o grupo butorfanol (GB que recebeu como MPA 1mg.kg-1 de butorfanol, ambos pela via intramuscular. Em seguida a indução ocorreu com a administração do agente anestésico inalatório, isoflurano 3V% e a manutenção anestésica com o mesmo agente 1,3 V%. Avaliaram-se a pressão arterial sistólica (PAS, frequência cardíaca (FC, frequência respiratória (f e temperatura corporal (TC. As avaliações foram realizadas: antes da MPA (M0; 15 minutos após MPA (M1; após indução anestésica (M2 e em diferentes momentos cirúrgicos (M3, M4, M5 e M6. A analgesia pós-operatória foi avaliada através da escala adaptada de dor em aves por dois avaliadores cegos aos tratamentos nos momentos: basal, e 1, 2, 4, 6, 8, 10, 12 e 24 horas pós-operatórias; sendo o resgate analgésico realizado quando uma pontuação maior ou igual a seis pontos de um total de 24 fosse observada.

  16. Recent disruption of an asteroid from the Eos family

    Science.gov (United States)

    Novaković, B.; Tsirvoulis, G.

    2014-07-01

    A key difficulty with searching for partially differentiated asteroids arises from the fact that a crust covers the exterior of the body, and, consequently, should hide the melted interior. This motivates an alternative approach of examining members of asteroid families, i.e., fragments of single large bodies, many of which were in the size regime capable of igneous differentiation, that have been disrupted by catastrophic collisions. Such families could provide a stratigraphic cross section across the interior of the parent asteroid [1]. With more than 10,000 known members, the Eos dynamical family is one of the most numerous and earliest recognized asteroid families [2]. Interestingly, the estimated ˜220-km-diameter parent body [3] is well within the size range capable of differentiation. Thus, existing family members should contain fragments of the deep interior. The Eos family has the highest diversity of taxonomic classes than any other known family [4]. Many members are of K spectral type, which is uncommon outside the family, and is similar to the spectra of CV, CK, CO, and CR carbonaceous chondrites [5]. This diversity leads to the suggestion that the Eos parent body was partially differentiated [4,6]. Thus, the Eos family may not only be a remnant of a partially differentiated parent body, but it could be the source of the CV-CK meteorite group. Here we report the discovery of a young subfamily of the Eos asteroid family. It may help understanding the mineralogical nature of the Eos asteroid family and of its parent body. By applying the hierarchical clustering method [7], we find an extremely compact 16-body cluster within the borders of the Eos family. We name the cluster (6733) 1992 EF, after its largest member. The statistical significance of this new cluster is estimated to be above 99%, indicating that its members share a common origin. All members of the cluster are found to be dynamically stable over long timescales. Backward numerical orbital

    Full Text Available Este artigo resume a avaliação de três programas de saúde pública em relação à sua eficácia e impacto sobre as desigualdades sociais na saúde. Foram examinadas a fluoração da água de abastecimento público no contexto brasileiro, a provisão de terapêutica antirretroviral para pacientes com Aids e a vacinação de idosos contra a gripe na cidade de São Paulo. As três intervenções foram consideradas efetivas, na medida em que propiciaram uma redução na carga de doença na população. No entanto, elas tiveram resultados conflitantes quanto ao impacto sobre as desigualdades em saúde. Concluiu-se, por fim, que os programas de saúde pública devem ser implementados com um alcance imediata e efetivamente universal, direcionando recursos adicionais aos grupos com mais necessidades de saúde. Essa estratégia reduziria, ao mesmo tempo, o nível geral de doença na população e as desigualdades na experiência de doenças entre os estratos sociais.

    Idiopathic hypereosinophilc syndrome is a disorder associated with clonally eosinophilic proliferation. The importance of FIP1-like-1-platelet-derived growth factor receptor-alpha (FIP1L1-PDGFRA) in the pathogenesis and classification of HES has been recently reported. In this study, we investigated the contribution of monocyte chemoattractant protein-1 (MCP-1)/CCL2 to chemotactic activity and protein kinase C delta (PKC delta in the human eosinophilic leukemia cell line EoL-1. These cells express CCR2 protein among the CC chemokine receptors (CCR1-5). MCP-1 induces strong migration of EoL-1 cells and the chemotaxis signal in response to MCP-1 involves a G(i)/G(o) protein, phospholipase C (PLC), PKC delta, p38 MAPK and NF-kappaB. MCP-1 activates p38 MAPK via G(i)/G(o) protein, PLC and PKC delta cascade. MCP-1 also induces NF-kappaB translocation and the activation is inhibited by PKC delta activation. The increase in the basal expression and activity of PKC delta in EoL-1 cells, compared to normal eosinophils, inhibits apoptosis in EoL-1 cells. Anti-apoptotic mechanism of PKC delta is related to inhibition of caspase 3 and caspase 9, but not to FIP1L1-PDGFRA. PKC delta functions as an anti-apoptotic molecule, and is involved in EoL-1 cell movement stimulated by MCP-1. This study contributes to an understanding of MCP-1 in eosinophil biology and pathogenic mechanism of eosinophilic disorders.

    Full Text Available The mottled skate, <em>Raja pulchraem>, is an economically valuable fish. However, due to a severe population decline, it is listed as a vulnerable species by the International Union for Conservation of Nature. To analyze its genetic structure and diversity, microsatellite markers were developed using 454 pyrosequencing. A total of 17,033 reads containing dinucleotide microsatellite repeat units (mean, 487 base pairs were identified from 453,549 reads. Among 32 loci containing more than nine repeat units, 20 primer sets (62% produced strong PCR products, of which 14 were polymorphic. In an analysis of 60 individuals from two <em>R. pulchra em>populations, the number of alleles per locus ranged from 1–10, and the mean allelic richness was 4.7. No linkage disequilibrium was found between any pair of loci, indicating that the markers were independent. The Hardy–Weinberg equilibrium test showed significant deviation in two of the 28 single-loci after sequential Bonferroni’s correction. Using 11 primer sets, cross-species amplification was demonstrated in nine related species from four families within two classes. Among the 11 loci amplified from three other <em>Rajidae> family species; three loci were polymorphic. A monomorphic locus was amplified in all three <em>Rajidae> family species and the <em>Dasyatidae> family. Two <em>Rajidae> polymorphic loci amplified monomorphic target DNAs in four species belonging to the Carcharhiniformes class, and another was polymorphic in two Carcharhiniformes species.

    This software is an improvement on Version 2, which was described in EOS MLS Level 1B Data Processing, Version 2.2, NASA Tech Briefs, Vol. 33, No. 5 (May 2009), p. 34. It accepts the EOS MLS Level 0 science/engineering data, and the EOS Aura spacecraft ephemeris/attitude data, and produces calibrated instrument radiances and associated engineering and diagnostic data. This version makes the code more robust, improves calibration, provides more diagnostics outputs, defines the Galactic core more finely, and fixes the equator crossing. The Level 1 processing software manages several different tasks. It qualifies each data quantity using instrument configuration and checksum data, as well as data transmission quality flags. Statistical tests are applied for data quality and reasonableness. The instrument engineering data (e.g., voltages, currents, temperatures, and encoder angles) is calibrated by the software, and the filter channel space reference measurements are interpolated onto the times of each limb measurement with the interpolates being differenced from the measurements. Filter channel calibration target measurements are interpolated onto the times of each limb measurement, and are used to compute radiometric gain. The total signal power is determined and analyzed by each digital autocorrelator spectrometer (DACS) during each data integration. The software converts each DACS data integration from an autocorrelation measurement in the time domain into a spectral measurement in the frequency domain, and estimates separately the spectrally, smoothly varying and spectrally averaged components of the limb port signal arising from antenna emission and scattering effects. Limb radiances are also calibrated.

    The atmosphere and the ocean are the two great fluids of the earth system. Changes in the coupling of these two fluids will have a profound impact on the Earth's climate and biogeochemical systems. Although changes in atmospheric composition and dynamics are the usual focus of global climate models, it is apparent that the ocean plays a critical role in modulating the magnitude and rate of these changes. The ocean is responsible for nearly half of the poleward heat flux as well as for a significant portion of the uptake of atmospheric carbon dioxide. However, the processes governing the flux of materials and energy between the ocean atmosphere are poorly understood. Such processes include not only physical and chemical dynamics, but also biological processes which act to modify the chemical composition of the ocean as well as the trapping of solar energy as heat in the upper water column. Thus it is essential that the ocean be studied as a complete system of physical, chemical, and biological processes. Overlapping measurements must be made for at least 10-15 years to resolve critical low frequency fluctuations. The present EOS plan relies heavily on non-EOS entities to provide critical data sets for ocean studies. Although such partnerships are usually beneficial, there are risks that must be considered in terms of data coverage, quality, resolution, and availability. A simple replacement of an EOS sensor with a non-EOS sensor based on the fact that they both measure the same quantities will not guarantee that critical measurements will be made to address IPCC priorities in the area of ocean processes. EOS must continue to pursue appropriate methods to ensure that such partner — provided measurements meet scientific requirements. Such methods are analogous to contigencies applied in the area of schedules, cost, and performance for instrument projects. EOS must foster strong ties between US scientists and their foreign counterparts, in order to develop

    Full Text Available A series of new <em>N>-acylhydrazone derivatives were synthesized in good yields through the reactions of dehydroabietic acid hydrazide with a variety of substituted arylaldehydes. The structures of the synthesized compounds were confirmed by IR, 1H- and 13C-NMR, ESI-MS, elemental analysis and single crystal X-ray diffraction. From the crystal structure of compound 4l, the C=N double bonds of these <em>N>-acylhydrazones showed (<em>E>-configuration, while the NMR data of compounds 4aq indicated the existence of two rotamers for each compound in solution. The target compounds were evaluated for their antibacterial activities against four microbial strains. The result suggested that several compounds exhibited pronounced antibacterial activities. Particularly, compound 4p exhibited good antibacterial activity against <em>Staphylococcus aureusem> and <em>Bacillus subtilisem> comparable to positive control. The possible antibacterial metabolism and the strategy for further optimization of this compound were also discussed.

    We report the simulation and experimental results of 1.3-μm InGaAsP/InP multiple quantum well (MQW) electro-absorption modulators (EAMs). In this work, the quantum confined Stark effect of the EAM is systematically analyzed through the finite element method. An optimized structure of the 1.3-μm InGaAsP/InP QW EAM is proposed for applications in 100 G ethernet. Then 1.3-μm InGaAsP/InP EAMs with f_−_3 _d_B bandwidth of over 20 GHz and extinction ratio over 20 dB at 3 V bias voltage are demonstrated. (paper)

    The Moderate Resolution Imaging Spectroradiometer (MODIS) will be the primary daily global monitoring sensor on the NASA Earth Observing System (EOS) satellites, scheduled for launch on the EOS-AM platform in June 1998 and the EOS-PM platform in December 2000. MODIS is a 36 channel radiometer covering 0·415-14·235 μm wavelengths, with spatial resolution from 250 m to 1 km at nadir. MODIS will be the primary EOS sensor for providing data on terrestrial biospheric dynamics and process activity. This paper presents the suite of global land products currently planned for EOSDIS implementation, to be developed by the authors of this paper, the MODIS land team (MODLAND). These include spectral albedo, land cover, spectral vegetation indices, snow and ice cover, surface temperature and fire, and a number of biophysical variables that will allow computation of global carbon cycles, hydrologic balances and biogeochemistry of critical greenhouse gases. Additionally, the regular global coverage of these variables will allow accurate surface change detection, a fundamental determinant of global change.

    Full Text Available A importância dos ativos intangíveis é crescente no cenário econômico atual, o que faz com que muitas pesquisas sejam dedicadas a eles. Nesse contexto está a avaliação da capacidade de criação de valor de tais ativos, com destaque para Pesquisa e Desenvolvimento (P&D. Já há muitas pesquisas sobre esse tema nos Estados Unidos, sendo escassa, no entanto, em mercados em desenvolvimento. Este trabalho tem como objetivo apresentar uma pesquisa sobre possível efeito econômico de investimentos em P&D nas empresas brasileiras. Para tanto se fez uma revisão bibliográfica sobre a questão em nível mundial e procedeu-se a uma pesquisa empírica nas empresas brasileiras listadas na Bovespa. Apesar dos baixos níveis de investimentos em P&D encontrados, verificou-se sinal de uma sensibilidade positiva do mercado brasileiro com relação aos gastos das empresas em P&D, o que pode ser um indicativo de que esse mercado considera estes como investimentos capazes de gerar benefícios futuros. Adicionalmente se aponta a necessidade de utilização de outros modelos, bem como também a consideração de outros fatores para amadurecer a questão que tem sido motivo de extensa pesquisa em outros mercados.

    Full Text Available O presente artigo, baseado em discurso dirigido à Sociedade Japonesa de Sociologia, na Universidade de Tohoku, recoloca as formulações centrais da sociologia pública, identificando os quatro estilos do fazer sociológico. Isso é feito à luz do cenário aberto com a profunda crise por que passa o sistema capitalista mundial. Mesmo ciente das diferentes tradições nacionais e da desigualdade internacional, e apesar delas, acreditamos que, como sociólogos, compartilhamos uma ambição e uma missão comum, que seria o combate ao paradigma baseado no fundamentalismo do mercado, que atualmente demonstra gravíssimos sinais de crise e de exaustão. Nesse sentido, resulta como tarefa primordial que os sociólogos canalizem as reações à crise em direção à criação de uma sociedade civil mais fortalecida e democrática, e de uma esfera pública mais robusta e inclusiva.

    Menikoff, Ralph [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2014-09-02

    A complete equation of state (EOS) for a molecular solid is derived utilizing a Helmholtz free energy. Assuming that the solid is nonconducting, phonon excitations dominate the specific heat. Phonons are approximated as independent quasi-harmonic oscillators with vibrational frequencies depending on the specific volume. The model is suitable for calibrating an EOS based on isothermal compression data and infrared/Raman spectroscopy data from high pressure measurements utilizing a diamond anvil cell. In contrast to a Mie-Gruneisen EOS developed for an atomic solid, the specific heat and Gruneisen coefficient depend on both density and temperature.

    Purpose: EOS (EOS imaging S.A, Paris, France) is an x-ray imaging system that uses slot-scanning technology in order to optimize the trade-off between image quality and dose. The goal of this study was to characterize the EOS system in terms of occupational exposure, organ doses to patients as well as image quality for full spine examinations. Methods: Occupational exposure was determined by measuring the ambient dose equivalents in the radiological room during a standard full spine examination. The patient dosimetry was performed using anthropomorphic phantoms representing an adolescent and a five-year-old child. The organ doses were measured with thermoluminescent detectors and then used to calculate effective doses. Patient exposure with EOS was then compared to dose levels reported for conventional radiological systems. Image quality was assessed in terms of spatial resolution and different noise contributions to evaluate the detector's performances of the system. The spatial-frequency signal transfer efficiency of the imaging system was quantified by the detective quantum efficiency (DQE). Results: The use of a protective apron when the medical staff or parents have to stand near to the cubicle in the radiological room is recommended. The estimated effective dose to patients undergoing a full spine examination with the EOS system was 290μSv for an adult and 200 μSv for a child. MTF and NPS are nonisotropic, with higher values in the scanning direction; they are in addition energy-dependent, but scanning speed independent. The system was shown to be quantum-limited, with a maximum DQE of 13%. The relevance of the DQE for slot-scanning system has been addressed. Conclusions: As a summary, the estimated effective dose was 290μSv for an adult; the image quality remains comparable to conventional systems

    2010-01-01

    This paper describes the successful operations of NASA's Earth Observing System (EOS) satellites over the past 10 years and the plans for the future. Excellent operations performance has been a key factor in the overall success of EOS. The EOS Program was conceived in the 1980s and began to take shape in the early 1990s. EOS consists of a series of satellites that study the Earth as an interrelated system. It began with the launch of Terra in December 1999, followed by Aqua in May 2002, and Aura in July 2004. A key EOS goal is to provide a long-term continuous data set to enable the science community to develop a better understanding of land, ocean, and atmospheric processes and their interactions. EOS has produced unprecedented amounts of data which are used all over the world free of charge. Mission operations have resulted in data recovery for Terra, Aqua, and Aura that have consistently exceeded mission requirements. The paper describes the ground systems and organizations that control the EOS satellites, capture the raw data, and distribute the processed science data sets. The paper further describes how operations have evolved since 1999. Examples of this evolution include (a) the implementation of new mission safety requirements for orbital debris monitoring; (b) technology upgrades to keep facilities at the state of the art; (c) enhancements to meet changing security requirements; and (d) operations management of the 2 international Earth Observing Constellations of 11 satellites known as the "Morning Constellation" and the "A-Train". The paper concludes with a view into the future based on the latest spacecraft status, lifetime projections, and mission plans.

    An Erasmus intensive programme has been successfully funded to run a Europe-lead summer school in Earth Observation for the years 2013 and 2014. The summer school, FORMAT-EO (FORmation of Multi-disciplinary Approaches to Training in Earth Observation) has been proposed and implemented by a consortium of eight partner institutions from five European countries. The consortium was facilitated through the NEREUS network. In the summer of 2013, 21 students from seven European institutions took part in the two week intensive course which involved a total of 28 teachers from six institutions. Students were from a variety of backgrounds including aeronautical engineering MSc students and PhD students in the areas of marine biology, earthquake engineering and measurement of trace gases in the atmosphere. The aims of FORMAT-EO were: To give students exposure to the wider applications of Earth Observation To highlight the interdisciplinary, collaborative and international nature of Earth Observation To offer an intensive course to better equip students with specialist skills required for a career in this field To provide expert advice on the development of careers in the EO market Partners were invited not only to recruit students for the course but to also teach at the school based on their specific area of expertise. This approach to the teaching provided a timetable which was wide-ranging and covered topics from EU policies for Earth Observation to fire detection from space and an introduction to interaction between radiation and matter. An important aspect of the course was the interactive nature of much of the teaching. A topic was introduced to the students through a lecture followed by an interactive tutorial providing students with hands-on experience of working with EO data and specialist software. The final days of the summer school were spent on group project work which required students to use all of the skills that they acquired during the course to challenge a

  7. PEG Enhancement for EM1 and EM2+ Missions

    Von der Porten, Paul; Ahmad, Naeem; Hawkins, Matt

    2018-01-01

    NASA is currently building the Space Launch System (SLS) Block-1 launch vehicle for the Exploration Mission 1 (EM-1) test flight. The next evolution of SLS, the Block-1B Exploration Mission 2 (EM-2), is currently being designed. The Block-1 and Block-1B vehicles will use the Powered Explicit Guidance (PEG) algorithm. Due to the relatively low thrust-to-weight ratio of the Exploration Upper Stage (EUS), certain enhancements to the Block-1 PEG algorithm are needed to perform Block-1B missions. In order to accommodate mission design for EM-2 and beyond, PEG has been significantly improved since its use on the Space Shuttle program. The current version of PEG has the ability to switch to different targets during Core Stage (CS) or EUS flight, and can automatically reconfigure for a single Engine Out (EO) scenario, loss of communication with the Launch Abort System (LAS), and Inertial Navigation System (INS) failure. The Thrust Factor (TF) algorithm uses measured state information in addition to a priori parameters, providing PEG with an improved estimate of propulsion information. This provides robustness against unknown or undetected engine failures. A loft parameter input allows LAS jettison while maximizing payload mass. The current PEG algorithm is now able to handle various classes of missions with burn arcs much longer than were seen in the shuttle program. These missions include targeting a circular LEO orbit with a low-thrust, long-burn-duration upper stage, targeting a highly eccentric Trans-Lunar Injection (TLI) orbit, targeting a disposal orbit using the low-thrust Reaction Control System (RCS), and targeting a hyperbolic orbit. This paper will describe the design and implementation of the TF algorithm, the strategy to handle EO in various flight regimes, algorithms to cover off-nominal conditions, and other enhancements to the Block-1 PEG algorithm. This paper illustrates challenges posed by the Block-1B vehicle, and results show that the improved PEG

    The assessment of spinal flexibility is essential for the planning of adolescent idiopathic scoliosis (AIS) surgery. Various radiographic methods have been used but none of them has shown any superiority. The new low-dose stereography system EOS (EOS imaging, Paris, France) captures whole body images in a single scan without vertical distortion. EOS is now used in routine clinical use for AIS follow-up. The aim of this study was to prospectively evaluate the feasibility and the reproducibility of a new suspension test during the EOS imaging for the assessment of spinal flexibility in AIS. Fifty AIS patients scheduled for surgery were prospectively included. For each patient, a standard EOS radiograph was obtained, then a suspension test in the EOS and a classic traction test on the cotrel frame were performed. The examinations were compared in terms of radiation exposure, tolerance, mean traction force, and Cobb angle reduction for each curve. Axial and sagittal reductions during suspension were analyzed on three-dimensional EOS reconstructions. The tolerance of the suspension test was lower than the traction test but it was less operator dependent. Radiation exposure was 7 times lower during the suspension test. Cobb angle reductions achieved in the proximal and main curves by the two tests were similar. The traction test achieved greater reduction of the distal curve. Flexibility in the axial plane and in the sagittal plane was analyzed with the suspension test. The reduction in apical rotation was not correlated with the reduction in Cobb angle. The EOS suspension test can be used for the assessment of spinal flexibility in AIS. It gives a global vision of the deformity with new flexibility indices in the axial and sagittal planes.

    Because pH plays a crucial role in several diseases, it is desirable to measure pH in vivo noninvasively and in a spatially localized manner. Spatial maps of pH were quantified in vitro, with a focus on method-based errors, and applied in vivo. In vitro and in vivo (13) C mapping were performed for various flip angles for bicarbonate (BiC) and CO2 with spectral-spatial excitation and spiral readout in healthy Lewis rats in five slices. Acute subcutaneous sterile inflammation was induced with Concanavalin A in the right leg of Buffalo rats. pH and proton images were measured 2 h after induction. After optimizing the signal to noise ratio of the hyperpolarized (13) C-bicarbonate, error estimation of the spectral-spatial excited spectrum reveals that the method covers the biologically relevant pH range of 6 to 8 with low pH error (< 0.2). Quantification of pH maps shows negligible impact of the residual bicarbonate signal. pH maps reflect the induction of acute metabolic alkalosis. Inflamed, infected regions exhibit lower pH. Hyperpolarized (13) C-bicarbonate pH mapping was shown to be sensitive in the biologically relevant pH range. The mapping of pH was applied to healthy in vivo organs and interpreted within inflammation and acute metabolic alkalosis models. © 2014 Wiley Periodicals, Inc.

    Full Text Available Reações de adsorção-dessorção de chumbo em solos são influenciadas por atributos de superfície dos colóides dos solos e pela composição da solução do meio. Este estudo avaliou o efeito do pH sobre a adsorção-dessorção de chumbo em Latossolos brasileiros. Amostras do horizonte A de cada solo, suspensas em Ca(NO32 5 mmol L-1, foram tituladas com HNO3 7 mmol L-1 ou solução saturada de Ca(OH2, para que fosse atingido o valor de pH estipulado em cada experimento (4,5, 5,5 e 6,5. Atingido o pH de equilíbrio, as amostras foram equilibradas com Pb(NO32, com vistas em obter uma concentração final de 0,15 mmol L-1 (relação solo:solução 1:100; força iônica 15 mmol L-1, por um período de 72 h. A dessorção foi realizada em Ca(NO32 5 mmol L-1, pH 5,5. O aumento do pH de 4,5 para 6,5 causou aumento da adsorção de até 16,7 vezes, um aumento médio de 2,9 vezes de pH 4,5 para 5,5; 1,4 vez de pH 5,5 para 6,5 e 4,2 vezes de pH 4,5 para 6,5. A relação Pb adsorvido/Pb adicionado foi, em média, de 0,33 para pH 4,5; 0,75 para pH 5,5 e 0,94 para pH 6,5. A fração média de Pb dessorvido (Pb dessorvido/Pb adsorvido decresceu de 0,36 a pH 4,5, para < 0,06 a pH 6,5. O efeito dos atributos do solo sobre a adsorção-dessorção de chumbo decresceu quando o pH aumentou, evidenciado por uma maior diferenciação na quantidade adsorvida pelos solos em valores mais baixos de pH. A adsorção de Pb foi positivamente correlacionada (e geralmente a fração dessorvida foi negativamente correlacionada com área superficial específica, CTC a pH 7,0, teores de caulinita, hematita, Fe2O3 extraídos pelo ditionito-citrato-bicarbonato de sódio e oxalato ácido de amônio e SiO2 e Fe2O3 extraídos pelo ataque sulfúrico. O fato de considerável fração de chumbo permanecer adsorvida em pH 4,5 mostra a reduzida disponibilidade deste metal em Latossolos, mesmo em baixos valores de pH.

    Building flexible and responsive processing and delivery systems is key to getting EO information used by researchers, policy agents and the public. There are typically three distinct processes we tackle to get product uptake: undertake research, operationalise the validated research, and deliver information and garner feedback in an appropriate way. In many cases however, the gaps between these process elements are large and lead to poor outcomes. Good research may be "lost" and not adopted, there may be resistance to uptake by government or NGOs of significantly better operational products based on EO data, and lack of accessibility means that there is no use of interactive science outputs to improve cross disciplinary science or to start a dialog with citizens. So one of the the most important tasks, if we wish to have broad uptake of EO information and accelerate further research, is to link these processes together in a formal but flexible way. One of the ways to operationalize research output is by building a platform that can take research code and scale it across much larger areas. In remote sensing, this is typically a system that has access to current and historical corrected imagery with a processing pipeline built over the top. To reduce the demand on high level scientific programmers and allowing cross disciplinary researchers to hack and play and refine, this pipeline needs to be easy to use, collaborative and link to existing tools to encourage code experimentation and reuse. It is also critical to have efficient, tight integration with information delivery and extension components so that the science relevant to your user is available quickly and efficiently. The rapid expansion of open data licensing has helped this process, but building top-down web portals and tools without flexibility and regard for end user needs has limited the use of EO information in many areas. This research reports on the operalization of a scale independent time series

    Full Text Available OBJETIVOS: Revisar os trabalhos publicados sobre os principais aspectos da bronquiolite obliterante pós-infecciosa, relacionados com sua história, etiologia, epidemiologia, fatores de risco, patogenia, alterações histológicas, manifestações clínicas, exames complementares, critérios diagnósticos, diagnóstico diferencial, tratamento e prognóstico. FONTES DOS DADOS: Realizou-se uma revisão não sistemática nas bases de dados MEDLINE e LILACS, selecionando-se 66 referências mais relevantes. SÍNTESE DOS DADOS: Na bronquiolite obliterante pós-infecciosa ocorre lesão do epitélio respiratório, e a gravidade clínica está relacionada aos diferentes graus de lesão e ao processo inflamatório. O diagnóstico baseia-se no quadro clínico, na exclusão dos principais diagnósticos diferenciais e no auxílio dos exames complementares. A tomografia computadorizada de alta resolução, principalmente com imagens em inspiração e expiração, possibilta a avaliação das pequenas vias aéreas. As provas de função pulmonar caracterizam-se por padrão obstrutivo fixo com redução acentuada do FEF25-75%. O tratamento não está bem estabelecido, e o uso de corticoides tem sido preconizado em forma de pulsoterapia ou por via inalatória em elevadas doses, no entanto, os dados da literatura a respeito de sua eficácia ainda são escassos. O prognóstico a longo prazo é variável, podendo haver melhora clínica ou evolução para insuficiência respiratória crônica e óbito. CONCLUSÃO: A bronquiolite obliterante pós-infecciosa é uma doença que cursa com elevada morbidade e deve ser abordada por equipe multidisciplinar com acompanhamento em longo prazo.

    Full Text Available O melhor aproveitamento do P, tanto o aplicado no cultivo quanto o residual do solo, em razão do uso de calcário em solos argilosos cultivados e adubados por muitos anos, pode ser viável. Objetivando avaliar o efeito do aumento do pH do solo e da aplicação de adubo fosfatado e calcário na semeadura sobre a disponibilidade de P e o seu acúmulo em plantas de soja, realizaram-se dois experimentos em Latossolo Vermelho Distrófico-LVD e Latossolo Vermelho Distroférrico-LVDf, argilosos, com elevados níveis de fertilidade. O delineamento experimental foi blocos casualizados, num fatorial 4x2x2: quatro níveis de pH, duas doses de P e duas de calcário, com quatro repetições. Cultivaram-se plantas de soja em vaso até a floração. Avaliaram-se o peso da massa seca, teor e acúmulo de P na parte aérea; teor de P e P remanescente no solo. A disponibilidade de P nos solos aumentou com a elevação do pH. Para o LVdf, houve interação entre pH e doses de P, os teores de P no solo aumentaram com o pH e com a aplicação de P. Para o LVD, houve interação entre pH e doses de calcário. O P remanescente foi reduzido pelo aumento do pH em ambos os solos. Nos dois experimentos, com o aumento do pH do solo houve incremento na produção de massa seca e de P acumulado. Em solos argilosos e com alto teor de P, a elevação do pH aumenta a disponibilidade de P, proporcionando maior produção de massa seca de soja.The best P employment, both applied in the culture as the P soil residual, is possible, due limestone use in clayey soils cultivated and fertilized for many years. Aiming at evaluating the pH increase in the soil and the effect of the application of phosphated fertilizer and lime on the sowing on the P availability and its accumulation in soybean plants, two experiments in oxisols, Haplortox (one LVD and the other LVDf, with high fertility levels, were carried out.

    In this work, a general equation of state (EOS) recently derived by Grzybowski et al. [Phys. Rev. E 83, 041505 (2011)] is applied to 51 molecular and ionic liquids in order to perform density scaling of pVT data employing the scaling exponent γ(EOS). It is found that the scaling is excellent in most cases examined. γ(EOS) values range from 6.1 for ammonia to 13.3 for the ionic liquid [C(4)C(1)im][BF(4)]. These γ(EOS) values are compared with results recently reported by us [E. R. López, A. S. Pensado, M. J. P. Comuñas, A. A. H. Pádua, J. Fernández, and K. R. Harris, J. Chem. Phys. 134, 144507 (2011)] for the scaling exponent γ obtained for several different transport properties, namely, the viscosity, self-diffusion coefficient, and electrical conductivity. For the majority of the compounds examined, γ(EOS) > γ, but for hexane, heptane, octane, cyclopentane, cyclohexane, CCl(4), dimethyl carbonate, m-xylene, and decalin, γ(EOS) liquids. For viscosities and the self-diffusion coefficient-temperature ratio, we have tested the relation linking EOS and dynamic scaling parameters, proposed by Paluch et al. [J. Phys. Chem. Lett. 1, 987-992 (2010)] and Grzybowski et al. [J. Chem. Phys. 133, 161101 (2010); Phys. Rev. E 82, 013501 (2010)], that is, γ = (γ(EOS)/φ) + γ(G), where φ is the stretching parameter of the modified Avramov relation for the density scaling of a transport property, and γ(G) is the Grüneisen constant. This relationship is based on data for structural relaxation times near the glass transition temperature for seven molecular liquids, including glass formers, and a single ionic liquid. For all the compounds examined in our much larger database the ratio (γ(EOS)/φ) is actually higher than γ, with the only exceptions of propylene carbonate and 1-methylnaphthalene. Therefore, it seems the relation proposed by Paluch et al. applies only in certain cases, and is really not generally applicable to liquid transport properties such as

    Rao, Mukund; Jayaraman, V.; Sridhara Murthi, K. R.; Kasturirangan, K.

    EO technology development will continue to have profound effects on spatial information activities, as we are seeing it today - the changing demand of GIS technology to understanding processes around us and its representation as maps. In the longer term, information needs will drive further RS and GIS technological developments - creating stringent demands for technology solutions for spatial data capture, integration and representation. The emergence of Spatial Business from the highly volatile and dynamic synergy of information, technology and access will see a truly Spatial Society. EO will have a major impact on day-to-day life of nations, communities and even an individual. It will become the One-stop source for information - spatial information at that - thus enabling not only development oriented activities but also Business GIS, quality research and Info-savvy communities. Internationally, there will be a mix of Government and Commercial satellites vying to provide information services to a wide variety of users. EO satellites are also becoming smaller, efficient and less costlier. Almost 5-6 commercial systems will orbit around the Earth in the foreseeable future to generate massive, seamless archives of high-resolution panchromatic and multispectral images - almost reducing the need for aerial surveys for photography and mapping. Reaching resolution of cm level and covering narrower and more spectral bands, the trend is to IMAGE the Earth in its entirety and organize Image Infrastructures. The race will be to imaginatively capture the market with the fullest archive of the globe and cater to any imaging demand of users. One will also see efficient satellite operations that will enable imaging any part of the globe with minimum turn-around time - reaching concepts of IMAGING ON DEMAND. The need of the hour is looking forward now towards how the EO technology can adapt itself to the changing scenario and the steps to be taken to sustain use of EO data it in

    2009-06-01

    An accurate EOS for polystyrene foam is necessary for analysis of numerous experiments in shock compression, inertial confinement fusion, and astrophysics. Plastic to gas ratios vary between various samples of foam, according to the density and cell-size of the foam. A matrix of compositions has been investigated, allowing prediction of foam response as a function of the plastic-to-air ratio. The EOS code CHEETAH allows participation of the air in the decomposition reaction of the foam, Differences between air-filled, nitrogen-blown, and CO2-blown foams are investigated, to estimate the importance of allowing air to react with plastic products during decomposition. Results differ somewhat from the conventional EOS, which are generated from values for plastic extrapolated to low densities.

    In even-even deformed nuclei up to now EO-transitions were found only between the states of the same spin belonging to Κ π = O + rotational bands. There is no forbidenness for EO-transitions between states belonging to bands with any other quantum number Κ provided both initial and final states have the same J π Κ values. EO-transitions may depopulate odd-parity states. In odd nuclei β-vibrational states are identified by transition with EO-components. Here transitions also proceed between states with the same J π K numbers. Even-even nuclide 160 Dy is the first nucleus where the EO-transitions between odd-parity states have been found

We examined roost selection in a breeding population of <em>B. barbastellusem> from the Abruzzo Lazio and Molise National Park (central Italy at three levels: woodland structure and management type; tree characteristics; and cavity characteristics. In 2001-2002, we fitted 31 adult <em>B. barbastellusem> (29 lactating females, one pregnant female and one male with 0.48g radio-tags and tracked them to their roost-trees.

The bats switched roosts frequently: 13 bats used more than one tree over the study period. A chi-square analysis showed that the roosts were not distributed at random across woodland categories: unmanaged woodland was positively selected, whereas shelterwood-harvested woodland was used in proportion to its availability, and ?pastures+scattered trees? was avoided. Twenty out of 33 roost trees were dead <em>Fagus sylvaticaem> trees; conversely, living <em>F. sylvaticaem> dominated in a tree sample obtained at random; dead trees were used more than expected (Χ² test, <em>P> <0.001.

    Full Text Available Os isótopos estáveis do carbono que eram utilizados em estudos ecológicos e paleoecológicos apresentaram um incremento nos últimos trinta anos, na utilização em estudos dietéticos em animais. Entretanto, existem poucas informações sobre o padrão metabólico e sobre as taxas de turnover do 13C em aves. O presente experimento estabeleceu curvas de substituição e taxas de movimentação do 13C no ovo e no fígado de aves de postura adultas, pela substituição da ração comercial por dietas compostas de grãos dos ciclos fotossintéticos C3 e C4, durante 50 dias. A diferença no conteúdo isotópico do delta per mil do carbono-13 (delta‰ 13C entre as duas dietas foi de 16,13‰. A taxa de substituição do 13C das dietas, nos tecidos, adequou-se num modelo exponencial, descrevendo o turnover do carbono nos tecidos analisados. As taxas de movimentação do 13C, nas aves alimentadas com dieta baseada em grãos C3, foi maior no fígado em relação ao ovo, com valores para a meia-vida de 2,9 e 3,7 dias, respectivamente. As aves que receberam ração com grãos C4 apresentaram uma taxa de turnover no ovo superior àquela obtida para o fígado, com meia-vida de 4,0 e 5,3 dias, respectivamente. Os valores do delta‰13C observados para ovo e fígado diferiram em aproximadamente 2‰ daqueles referentes às dietas.The stable carbon isotopes used in ecology and paleoecology during the last 30 years has now been used in dietary studies of animals. However, there are not enough studies on the metabolism patterns and turnover rates of the 13C in avian. This experiment established the turnover rates of the 13C in egg and liver tissues of adult laying hens through the substitution of commercial diets by diets containing C3 and C4 photosynthetic cycle grains for 50 days. The delta‰13C difference in two diets contents was 16.13‰. The diets 13C turnover rates in tissues were adapted in an exponential model that describes the isotopic carbon

    EoL-1 cells differentiate into eosinophils in the presence of n-butyrate, but the mechanism has remained to be elucidated. Because n-butyrate can inhibit histone deacetylases, we hypothesized that the inhibition of histone deacetylases induces the differentiation of EoL-1 cells into eosinophils. In this study, using n-butyrate and two other histone deacetylase inhibitors, apicidin and trichostatin A, we have analyzed the relationship between the inhibition of histone deacetylases and the differentiation into eosinophils in EoL-1 cells. It was demonstrated that apicidin and n-butyrate induced a continuous acetylation of histones H4 and H3, inhibited the proliferation of EoL-1 cells without attenuating the level of FIP1L1-PDGFRA mRNA, and induced the expression of markers for mature eosinophils such as integrin beta7, CCR1, and CCR3 on EoL-1 cells, while trichostatin A evoked a transient acetylation of histones and induced no differentiation into eosinophils. These findings suggest that the continuous inhibition of histone deacetylases in EoL-1 cells induces the differentiation into mature eosinophils.

Foi mais frequente em estabelecimentos públicos com internação (17,8% do total, da administração estadual (26,3% e da Região Sul (6,6% e, em geral, era parcial (apenas para algumas áreas, como despesas emergenciais, material de consumo e permanentes, serviços de terceiros e pessoal. Quanto à natureza jurídica, 83,7% dos 2.011 estabelecimentos públicos que referiram alguma autonomia são da administração direta. A atribuição de autonomia financeira a estabelecimentos públicos de saúde parece ser definição política local, que não se prende necessariamente a mudanças de natureza jurídica. Ainda assim, confirmou-se um espectro crescente de maior autonomia segundo natureza jurídica, em que estabelecimentos da administração direta da saúde são os menos autônomos e as sociedades empresariais as mais autônomas; 85,8% dos 45.394 estabelecimentos privados tinham alguma autonomia financeira.

    The Earth Observing-One (EO-1) satellite, launched in November of 2000, will complete its sixteenth and final year of operation at the end of calendar year 2016. Observations from the Hyperion Imaging Spectrometer on board EO-1 have contributed to hundreds of papers in refereed journals, conference proceeds and other presentations. The EO-1 Hyperion imaging spectrometer is the first and longest operating instrument that provides visible to shortwave infrared science-grade data from orbit. Hyperion has been used to study a variety of natural and anthropogenic phenomena including hazards and catastrophes, agricultural health and productivity, ecological disturbance/development, and land use/land cover change. As an example, Hyperion has been used in hazard and catastrophe studies to monitor and assess effects of tsunamis, earthquakes, volcanic eruptions, mudslides, tornadoes, hurricanes, wild-fires (natural and human ignited), oil spills, and the aftermath of world trade center bombing. This presentation summarizes the current status of EO-1 Hyperion in terms of key scientific findings to date and presents future plans for exploiting the upward of 90,000 scenes expected to be archived at USGS EROS by the end of the mission. Hyperion serves as the heritage orbital spectrometer for future global platforms, including the proposed NASA Hyperspectral Infrared Imager (HyspIRI) and the forthcoming German satellite, EnMAP. A key EO-1 mission goal was to evaluate the ability of satellite high spectral resolution imaging to characterize terrestrial surface state and processes at 30 m resolution. Researchers engaged in NASA's Terrestrial Ecology, Carbon Science, Land Use Change and other programs using the EO-1 Hyperion imaging spectrometer have achieved results with accuracies far exceeding those reached with the current spaceborne fleet of multispectral sensors. Hyperion data provide several advantages over data from multispectral satellite systems: they inherently provide

    A questionnaire survey and interviews were conducted in households and end-of-life (EoL) mobile phone business centres in Hong Kong. Widespread Internet use, combined with the rapid evolution of modern social networks, has resulted in the more rapid obsolescence of mobile phones, and thus a tremendous increase in the number of obsolete phones. In 2013, the volume of EoL mobile phones generated in Hong Kong totalled at least 330 tonnes, and the amount is rising. Approximately 80% of electronic waste is exported to Africa and developing countries such as mainland China or Pakistan for recycling. However, the material flow of the large number of obsolete phones generated by the territory's households remains unclear. Hence, the flow of EoL mobile phones in those households was analysed, with the average lifespan of a mobile phone in Hong Kong found to be just under two years (nearly 23 months). Most EoL mobile phones are transferred to mainland China for disposal. Current recycling methods are neither environmentally friendly nor sustainable, with serious implications for the environment and human health. The results of this analysis provide useful information for planning the collection system and facilities needed in Hong Kong and mainland China to better manage EoL mobile phones in the future.

    2010-12-01

    One topic that is beginning to influence the systems that support these goals is that of Information Technology (IT) Security. Unsecure systems are vulnerable to increasing attacks and other negative consequences; sponsoring agencies are correspondingly responding with more refined policies and more stringent security requirements. These affect how EO systems can meet the goals of data and service interoperability and harmonization through open access, transformation and visualization services. Contemporary systems, including the vision of a system-of-systems (such as GEOSS, the Global Earth Observation System of Systems), utilize technologies that support a distributed, global, net-centric environment. These types of systems have a high reliance on the open systems, web services, shared infrastructure and data standards. The broader IT industry has developed and used these technologies in their business and mission critical systems for many years. Unfortunately, the IT industry, and their customers have learned the importance of protecting their assets and resources (computing and information) as they have been forced to respond to an ever increasing number and more complex illegitimate “attackers”. This presentation will offer an overview of work done by the CEOS WGISS organization in summarizing security threats, the challenges to responding to them and capturing the current state of the practice within the EO community.

  4. Microglia P2Y13 Receptors Prevent Astrocyte Proliferation Mediated by P2Y1 Receptors

    Full Text Available Cerebral inflammation is a common feature of several neurodegenerative diseases that requires a fine interplay between astrocytes and microglia to acquire appropriate phenotypes for an efficient response to neuronal damage. During brain inflammation, ATP is massively released into the extracellular medium and converted into ADP. Both nucleotides acting on P2 receptors, modulate astrogliosis through mechanisms involving microglia-astrocytes communication. In previous studies, primary cultures of astrocytes and co-cultures of astrocytes and microglia were used to investigate the influence of microglia on astroglial proliferation induced by ADPβS, a stable ADP analog. In astrocyte cultures, ADPβS increased cell proliferation through activation of P2Y1 and P2Y12 receptors, an effect abolished in co-cultures (of astrocytes with ∼12.5% microglia. The possibility that the loss of the ADPβS-mediated effect could have been caused by a microglia-induced degradation of ADPβS or by a preferential microglial localization of P2Y1 or P2Y12 receptors was excluded. Since ADPβS also activates P2Y13 receptors, the contribution of microglial P2Y13 receptors to prevent the proliferative effect of ADPβS in co-cultures was investigated. The results obtained indicate that P2Y13 receptors are low expressed in astrocytes and mainly expressed in microglia. Furthermore, in co-cultures, ADPβS induced astroglial proliferation in the presence of the selective P2Y13 antagonist MRS 2211 (3 μM and of the selective P2Y12 antagonist AR-C66096 (0.1 μM, suggesting that activation of microglial P2Y12 and P2Y13 receptors may induce the release of messengers that inhibit astroglial proliferation mediated by P2Y1,12 receptors. In this microglia-astrocyte paracrine communication, P2Y12 receptors exert opposite effects in astroglial proliferation as a result of its cellular localization: cooperating in astrocytes with P2Y1 receptors to directly stimulate proliferation and in

    The P-type ATPases (P-ATPases) are present in all living cells where they mediate ion transport across membranes on the expense of ATP hydrolysis. Different ions which are transported by these pumps are protons like calcium, sodium, potassium, and heavy metals such as manganese, iron, copper, and zinc. Maintenance of the proper gradients for essential ions across cellular membranes makes P-ATPases crucial for cell survival. In this study, characterization of two families of P-ATPases including P-ATPase 13A1 and P-ATPase 13A3 protein was compared in two different insect species from different orders. According to the conserved motifs found with MEME, nine motifs were shared by insects of 13A1 family but eight in 13A3 family. Seven different insect species from 13A1 and five samples from 13A3 family were selected as the representative samples for functional and structural analyses. The structural and functional analyses were performed with ProtParam, SOPMA, SignalP 4.1, TMHMM 2.0, ProtScale and ProDom tools in the ExPASy database. The tertiary structure of Bombus terrestris as a sample of each family of insects were predicted by the Phyre2 and TM-score servers and their similarities were verified by SuperPose server. The tertiary structures were predicted via the "c3b9bA" model (PDB Accession Code: 3B9B) in P-ATPase 13A1 family and "c2zxeA" model (PDB Accession Code: 2ZXE) in P-ATPase 13A3 family. A phylogenetic tree was constructed with MEGA 6.06 software using the Neighbor-joining method. According to the results, there was a high identity of P-ATPase families so that they should be derived from a common ancestor however they belonged to separate groups. In protein-protein interaction analysis by STRING 10.0, six common enriched pathways of KEGG were identified in B. terrestris in both families. The obtained data provide a background for bioinformatic studies of the function and evolution of other insects and organisms. Copyright © 2017 Elsevier Ltd. All rights

    The EO-1 satellite is part of NASA's New Millennium Program (NMP). It consists of three imaging sensors: the multi-spectral Advanced Land Imager (ALI), Hyperion and Atmospheric Corrector. Hyperion provides a high-resolution hyperspectral imager capable of resolving 220 spectral bands (from 0.4 to 2.5 micron) with a 30 m resolution. The instrument images a 7.5 km by 100 km land area per image. Hyperion is currently the only space-borne HSI data source since the launch of EO-1 in late 2000. The discussion begins with the unique capability of hyperspectral sensing to coastal characterization: (1) most ocean feature algorithms are semi-empirical retrievals and HSI has all spectral bands to provide legacy with previous sensors and to explore new information, (2) coastal features are more complex than those of deep ocean that coupled effects are best resolved with HSI, and (3) with contiguous spectral coverage, atmospheric compensation can be done with more accuracy and confidence, especially since atmospheric aerosol effects are the most pronounced in the visible region where coastal feature lie. EO-1 data from Chesapeake Bay from 19 February 2002 are analyzed. In this presentation, it is first illustrated that hyperspectral data inherently provide more information for feature extraction than multispectral data despite Hyperion has lower SNR than ALI. Chlorophyll retrievals are also shown. The results compare favorably with data from other sources. The analysis illustrates the potential value of Hyperion (and HSI in general) data to coastal characterization. Future measurement requirements (air borne and space borne) are also discussed.

    The experimental densities for the binary systems of an ionic liquid and an alkanol {1-ethyl-3-methylimidazolium ethylsulfate [EMIM] + [EtSO 4 ] - + methanol or 1-propanol or 2-propanol} were determined at T = (298.15, 303.15, and 313.15) K. The excess molar volumes for the above systems were then calculated from the experimental density values for each temperature. The Redlich-Kister smoothing polynomial was used to fit the experimental results and the partial molar volumes were determined from the Redlich-Kister coefficients. For all the systems studied, the excess molar volume results were negative over the entire composition range for all the temperatures. The excess molar volumes were correlated with the pentic four parameter virial (PFV) equation of state (EoS) model

    Due to the context-sensitive nature of entrepreneurial orientation (EO), it is imperative to in-depth explore the EO-performance mechanism in China at its critical, specific stage of economic reform. Under the context of “reverse internationalization” by Chinese global startup original equipment manufacturers (OEMs), this paper aims to manifest the unique links and complicated interrelationships between the individual EO dimensions and firm performance. Using structural equation modeling, we found that during reverse internationalization, proactiveness is positively related to performance; risk taking is not statistically associated with performance; innovativeness is negatively related to performance. The proactiveness-performance relationship is mediated by Strategic flexibility and moderated by social networking relationships.

    Due to the context-sensitive nature of entrepreneurial orientation (EO), it is imperative to in-depth explore the EO-performance mechanism in China at its critical, specific stage of economic reform. Under the context of "reverse internationalization" by Chinese global startup original equipment manufacturers (OEMs), this paper aims to manifest the unique links and complicated interrelationships between the individual EO dimensions and firm performance. Using structural equation modeling, we found that during reverse internationalization, proactiveness is positively related to performance; risk taking is not statistically associated with performance; innovativeness is negatively related to performance. The proactiveness-performance relationship is mediated by Strategic flexibility and moderated by social networking relationships. The dynamic and complex institutional setting, coupled with the issues of overcapacity and rising labor cost in China may explain why our distinctive results occur. This research advances the understanding of how contingent factors (social network relationships and strategic flexibility) facilitate entrepreneurial firms to break down institutional barriers and reap the most from EO. It brings new insights into how Chinese global startup OEMs draw on EO to undertake reverse internationalization, responding the calls for unraveling the heterogeneous characteristics of EO sub-dimensions and for more contextually-embedded treatment of EO-performance associations.

    The spinal penetration index (SPI) quantifies the portion of the rib cage occupied by vertebrae. When measured by computed tomography (CT) or magnetic resonance imaging, SPI can only be determined in the reclining position, which modifies spinal and thoracic morphology. CT results in high radiation exposure. The authors studied rib cage and spinal morphology using low-dose biplanar stereoradiography and their impact on respiratory function in adolescent idiopathic scoliosis (AIS). In eighty thoracic AIS patients, a slot-scanning radiologic device allowing simultaneous acquisition of orthogonal images and 3D reconstructions with low exposure to radiation (EOS) was used to determine thoracic volume, mean spinal penetration index (SPIm), apical spinal penetration index (SPIa), main thoracic (MT) curve Cobb angle, T4-T12 kyphosis, and apical vertebral rotation (AVR). Thoracic volume was correlated with thoracic kyphosis (r = 0.31, p = 0.006), but not with SPI, MT Cobb angle, or AVR. SPIm and SPIa were negatively correlated with thoracic kyphosis. Forced vital capacity and forced expiratory volume in 1 s were significantly lower in the hypokyphotic patients (p = 0.04, p = 0.03, respectively) and correlated with thoracic volume and T4-T12 kyphosis. No correlation was found between spinal penetration indices and pulmonary function tests, but SPIm was significantly greater in patients with obstructive syndrome (p = 0.01). With little radiation exposure, EOS biplanar stereoradiography permits routine imaging is a functional standing position. Hypokyphotic patients had significantly decreased FEV1 and FVC. SPIm was significantly higher in patients with obstructive syndrome.

    The RADIOM model, [1-2], allows one to implement non-LTE atomic physics with a very low extra CPU cost. Although originally heuristic, RADIOM has been physically justified [3] and some accounting for auto-ionization has been included [2]. RADIOM defines an ionization temperature Tz derived from electronic density and actual electronic temperature Te. LTE databases are then queried for properties at Tz and NLTE values are derived from them. Some hydro-codes (like FAST at NRL, Ramis' MULTI, or the CRASH code at U.Mich) use inverse EOS starting from the total internal energy Etot and returning the temperature. In the NLTE case, inverse EOS requires to solve implicit relations between Te, Tz, and Etot. We shall describe these relations and an efficient solver successively implemented in some of our codes.

    We present an exact analytical bouncing solution for a closed universe filled with only one exotic fluid with negative pressure, obeying a generalized equation of state (GEoS) of the form p(ρ) = Aρ+Bρ{sup λ}, where A, B and λ are constants. In our solution A = -1/3, λ = 1/2, and B < 0 is kept as a free parameter. For particular values of the initial conditions, we find that our solution obeys the null energy condition (NEC), which allows us to reinterpret the matter source as that of a real scalar field, φ, with a positive kinetic energy and a potential V(φ). We numerically compute the scalar field as a function of time as well as its potential V(φ), and we find an analytical function for the potential that fits very accurately with the numerical data obtained. The shape of this potential can be well described by a Gaussian-type of function, and hence there is no spontaneous symmetry minimum of V(φ). We show numerically that the bouncing scenario is structurally stable in a small vicinity of the value A = -1/3. We also include the study of the evolution of the linear fluctuations due to linear perturbations in the metric. These perturbations show an oscillatory behavior near the bouncing and approach a constant at large scales. (orig.)

In this respect, standardized quantitative sampling techniques, like Owl pellets analysis can enable not only to enhance faunistic knowledges, but also to estimate the actual absence probability of a given taxon "m", lacking from the diet of an individual raptor. For the last purpose, the relevant frequencies of "m" in the other ecologically similar sites of the same raptor species diets are averaged ($f_m$ : the relevant standard error (multiplicated by a coefficient, according to the desired degree of accuracy, in relation of the integral of probabilities subtracted ($overline{F}_m - a E$: then, the probability that a single specimen is not pertaining to "m" is obtained ($P_0 = 1 - F_m + a E$; lastly, the desiderate accuracy probability ($P_d$ is chosen.

    This work was developed in the context of the ESA Heterogeneous Missions Accessibility (HMA) project, whose main objective is to involve the stakeholders, namely National space agencies, satellite or mission owners and operators, in an harmonization and standardization process of their ground segment services and related interfaces. Among HMA objectives was the specification, conformance testing, and experimentation of two Extension Packages (EPs) of the ebRIM Application Profile (AP) of the OGC Catalog Service for the Web (CSW) specification: the Earth Observation Products (EO) EP (OGC 06-131) and the Cataloguing of ISO Metadata (CIM) EP (OGC 07-038). Our contributions have included the development and deployment of Reference Implementations (RIs) for both the above specifications, and their integration with the ESA Service Support Environment (SSE). The RIs are based on the GI-cat framework, an implementation of a distributed catalog service, able to query disparate Earth and Space Science data sources (e.g. OGC Web Services, Unidata THREDDS) and to expose several standard interfaces for data discovery (e.g. OGC CSW ISO AP). Following our initial planning, the GI-cat framework has been extended in order to expose the CSW.ebRIM-CIM and CSW.ebRIM-EO interfaces, and to distribute queries to CSW.ebRIM-CIM and CSW.ebRIM-EO data sources. We expected that a mapping strategy would suffice for accommodating CIM, but this proved to be unpractical during implementation. Hence, a model extension strategy was eventually implemented for both the CIM and EO EPs, and the GI-cat federal model was enhanced in order to support the underlying ebRIM AP. This work has provided us with new insights into the different data models for geospatial data, and the technologies for their implementation. The extension is used by suitable CIM and EO profilers (front-end mediator components) and accessors (back-end mediator components), that relate ISO 19115 concepts to EO and CIM ones. Moreover

    EoL-1 cells have a FIP1L1-PDGFRA fusion gene which causes the transformation of eosinophilic precursor cells into leukemia cells. Recently, we suggested that the induction of differentiation of EoL-1 cells into eosinophils by the HDAC inhibitors apicidin and n-butyrate is due to the continuous inhibition of HDACs. However, neither apicidin nor n-butyrate inhibited the expression of FIP1L1-PDGFRA mRNA, although both these inhibitors suppressed cell proliferation. Therefore, in this study, we analyzed whether the levels of FIP1L1-PDGFRalpha protein and phosphorylated-Stat5 involved in the signaling for the proliferation of EoL-1 cells are attenuated by HDAC inhibitors. EoL-1 cells were incubated in the presence of apicidin, TSA or n-butyrate. FIP1L1-PDGFRalpha and phosphorylated-Stat5 were detected by Western blotting. Treatment of EoL-1 cells with apicidin at 100 nM or n-butyrate at 500 microM decreased the levels of FIP1L1-PDGFRalpha protein and phosphorylated-Stat5, while that with trichostatin A at 30 nM did not. The decrease in the level of FIP1L1-PDGFRalpha protein caused by apicidin and n-butyrate might be one of the mechanisms by which EoL-1 cells are induced to differentiate into eosinophils by these HDAC inhibitors.

    Full Text Available Resumo Os portadores da doença celíaca, uma enteropatia, apresentam intolerância ao glúten e a restrição de alimentos que o contenham mostra-se eficaz na normalização da função intestinal e das manifestações clínicas. O objetivo do presente estudo foi avaliar o efeito da adição de colágeno em pó e em fibra nas características estruturais, tecnológicas e sensoriais de pães sem glúten, elaborados com farinha de arroz. Primeiramente, foram realizadas adições de 2%, 4%, 6% e 8% de colágeno, sob as formas em pó e em fibra, em pães elaborados com farinha de arroz, sendo estes avaliados quanto às suas características tecnológicas: volume específico, firmeza do miolo e cor da crosta e do miolo. O pão que apresentou as melhores características tecnológicas foi caracterizado quanto à sua composição química (proteínas, lipídios, cinzas, umidade e carboidratos, avaliado quanto às perdas decorrentes da cocção e submetido à análise sensorial. As massas cruas dos pães adicionados com o colágeno em fibra, assim como a massa do pão padrão (sem adição de colágeno, foram avaliadas através de reologia e microscopia eletrônica de varredura. A adição de colágeno aos pães elaborados com farinha de arroz não colaborou para a formação de uma rede semelhante à formada pelo glúten. O pão da formulação com 4% de colágeno em fibra apresentou as características tecnológicas mais próximas ao esperado, não diferindo significativamente quanto à composição química, do pão padrão. Por meio da análise sensorial, constatou-se que os pães sem glúten (padrão e com 4% de colágeno em fibra obtiveram aceitação sensorial superior a 75%. Conclui-se, com o estudo, que é possível adicionar colágeno em pães sem glúten, sendo que o pão adicionado de 4% de colágeno em fibra apresentou características mais próximas às do pão padrão testado.

    Bovine lactoferricin P13 (LfcinB-P13) is a peptide derived from LfcinB. In the present study, the effect of LfcinB-P13 on the human liver cancer cell line SMMC7721 was investigated in vitro and in vivo . The results of the present study indicate that LfcinB-P13 significantly decreased SMMC7721 cell viability in vitro (P=0.032 vs. untreated cells), while exhibiting low cytotoxicity in the wild-type liver cell line L02. In addition, the rate of apoptosis in SMMC7721 cells was significantly increased following treatment with 40 and 60 µg/ml LfcinB-P13 (P=0.0053 vs. the control group), which was associated with an increase in the level of reactive oxygen species (ROS) and the activation of caspase-3 and -9. Furthermore, ROS chelation led to the suppression of LfcinB-P13-mediated caspase-3 and -9 activation in SMMC7721 cells. LfcinB-P13 was demonstrated to markedly inhibit tumor growth in an SMMC7721-xenograft nude mouse model. The results of the present study indicate that LfcinB-P13 is a novel candidate therapeutic agent for the treatment of liver cancer.

    There is a growing demand for sustainable methods in research and development, where instead of hazardous chemicals, an aqueous medium is chosen to perform biological reactions. In this Perspective, we examine the history and current methodology of using enzymes to generate artificial single-stranded DNA. By using traditional solid-phase phosphoramidite chemistry as a metric, we also explore criteria for the method of template-independent enzymatic oligonucleotide synthesis (TiEOS). As its key component, we delve into the biology of one of the most enigmatic enzymes, terminal deoxynucleotidyl transferase (TdT). As TdT is found to exponentially increase antigen receptor diversity in the vertebrate immune system by adding nucleotides in a template-free manner, researchers have exploited this function as an alternative to the phosphoramidite synthesis method. Though TdT is currently the preferred enzyme for TiEOS, its random nucleotide incorporation presents a barrier in synthesis automation. Taking a closer look at the TiEOS cycle, particularly the coupling step, we find it is comprised of additions > n+1 and deletions. By tapping into the physical and biochemical properties of TdT, we strive to further elucidate its mercurial behavior and offer ways to better optimize TiEOS for production-grade oligonucleotide synthesis.

    11p13 and 11p15 loss of heterozygosity (LOH) in Wilms tumor (WT), the commonest molecular pathogenetic event in WT, shows variation in different parts of the world. The present study looked for the presence of 11p13 and 11p15 LOH as well as nephrogenic rests in WT occurring in India. Twenty-two cases of WT were subjected to thorough pathological examination for presence of nephrogenic rests. Fresh frozen tissue was evaluated for LOH at 11p13 and 11p15, using PCR for microsatellite markers. Among twenty-two consecutive cases of WT, 20 were unilateral and 2 were bilateral. 6/22 showed LOH at 11p13 (27.7 %) and 1/22 showed LOH at 11p15 (4.54 %). 2/22 cases showed presence of nephrogenic rests. One of the cases with LOH at 11p13 had intralobar nephrogenic rest in the adjacent kidney. One specimen had perilobar nephrogenic rest in the adjacent kidney but did not show LOH for either 11p13 or 11p15 in the tumor. LOH at 11p13 is seen in 27.27 % of WT in India, which is similar to reports in the English language literature. LOH at 11p15 was seen in 4.54 % of WT, which is lower than that reported from Western subjects.

  7. Pos-modernidade ou antimodernidade? Uma reflexão em torno do debate moderno/pós-moderno

    Full Text Available Este ensaio constitui-se em uma reflexão histórica em torno do debate moderno/pós-moderno. O objetivo do texto, de modo mais preciso, é apresentar e rebater algumas das críticas que pensadores – tais como Habermas, Rouanet, Giddens e Lipovetsky – lançam em direção às chamadas teorias pós-modernas, acusando-as de serem, na verdade, discursos de antimodernidade. Na visão desses autores, não há uma ruptura real entre a modernidade e aquilo que tem sido chamado de “pós-modernidade”. Contrariamente a essa perspectiva, o trabalho ora apresentado parte do pressuposto de que há, de fato, um conjunto de deslocamentos – descontinuidades, desencaixes, pontos de ruptura – que separam uma matriz moderna de uma matriz pós-moderna.

    Currently, two approaches are being used to predict the changes in retrograde gas condensate composition and estimate the pressure depletion behavior of gas condensate reservoirs. The first approach uses the equation of states whereas the second uses empirical correlations. Equations of states (EOS) are poor predictive tools for complex hydrocarbon systems. The EOS needs adjustment against phase behavior data of reservoir fluid of known composition. The empirical correlation does not involve numerous numerical computations but their accuracy is limited. This study presents two general regression neural network (GRNN) models. The first model, GRNNM1, is developed to predict dew point pressure and gas compressibility at dew point using initial composition of numerous samples while the second model, GRNNM2, is developed to predict the changes in well stream effluent composition at any stages of pressure depletion. GRNNM2 can also be used to determine the initial reservoir fluid composition using dew point pressure, gas compressibility at dew point, and reservoir temperature. These models are based on analysis of 142 sample of laboratory studies of constant volume depletion (CVD) for gas condensate systems forming a total of 1082 depletion stages. The database represents a wide range of gas condensate systems obtained worldwide. The performance of the GRNN models has been compared to simulation results of the equation of state. The study shows that the proposed general regression neural network models are accurate, valid, and reliable. These models can be used to forecast CVD data needed for many reservoir engineering calculations in case laboratory data is unavailable. The GRNN models save computer time involved in EOS calculations. The study also show that once these models are properly trained they can be used to cut expenses of frequent sampling and laborious experimental CVD tests required for gas condensate reservoirs. 55 refs., 13 figs., 6 tabs.

    Full Text Available A conversão do cerrado nativo em sistemas agropecuários pode alterar com o passar dos anos de cultivo os teores de C e N, bem como o sinal isotópico do δ13C e δ15N do solo. Desta forma, o objetivo deste trabalho foi avaliar os teores de C, N e abundância natural de δ13C e δ15N no perfil do solo em uma cronossequência de agricultura sob sistema plantio direto (SPD no cerrado goiano. Para isso, em Montividiu, GO, foram selecionadas áreas sob SPD com diferentes tempos de implantação: SPD com três anos de implantação (SPD3, SPD com 15 anos de implantação (SPD15 e SPD com 20 anos de implantação (SPD20, as quais foram comparadas com áreas de cerrado nativo (CE e pastagem (PA. Foram coletadas amostras de solo nas profundidades de 0,00-0,05; 0,05-0,10; 0,10-0,20; 0,20-0,30; 0,30-0,40; 0,40-0,50; 0,50-0,60; 0,60-0,80; e 0,80-1,00 m. O solo das áreas de estudo foi classificado como Latossolo Vermelho distroférrico. O manejo do solo sob SPD após 20 anos aumentou os teores de C e N na camada superficial do solo (0,00-0,05 m, em relação às outras áreas avaliadas. Nas demais profundidades avaliadas, observou-se que está ocorrendo aumento nos teores C e N com o passar dos anos de adoção do SPD (três para 15 anos; no entanto, tais áreas ainda não foram capazes de recuperar os teores desses elementos em relação à vegetação nativa de CE. Por meio dos resultados de δ13C, pôde-se constatar que a origem da MOS nas áreas de SPD é referente à plantas do ciclo fotossintético C4. Verificou-se que até os 0,30 m do perfil do solo os resultados de δ13C estão reduzindo com o passar dos anos de adoção do SPD. Os menores e maiores valores de δ15N foram encontrados nas áreas de CE e PA, SPD3, enquanto SPD15 e SPD20 apresentaram valores intermediários de δ15N, em relação às demais áreas avaliadas.

    Full Text Available Avaliou-se a possibilidade de redução da concentração do fósforo inorgânico em dietas formuladas para suínos de acordo com o conceito de proteína ideal, utilizando-se um modelo experimental para o estudo do fluxo do P no metabolismo animal. Utilizaram-se 20 suínos machos castrados em delineamento em blocos ao acaso, com cinco tratamentos e quatro repetições. Os tratamentos corresponderam à adição de 0, 250, 500, 750 e 1000UF/kg de dieta. No primeiro dia da fase experimental, os animais receberam, por via endovenosa, uma solução radioativa com 7,4MBq de 32P. No final do período experimental, os animais foram sacrificados e coletaram-se amostras de tecidos do músculo Longissimus dorsi, coração, fígado, rins e ossos. Pode-se reduzir em 50% a suplementação de P em dietas para suínos em crescimento adicionando-se 750UF/kg de dieta, em rações à base de milho e farelo de soja, balanceadas de acordo com o conceito de proteína ideal, diminuindo-se significativamente a excreção de P nas fezes.The study was developed to evaluate a possible of reduction of the inorganic P concentration in diets formulated for pigs in agreement with the concept of ideal protein, using Lopes et al. model. Twenty male pigs were used in a randomized blocks design, with five treatments and four replicates. The animals were housed in metabolic cages for 17 days, being 10 days for adaptation and seven days for collection of feces and urine. Samples of blood were collected for five days. On the first day of the experimental phase, each animal was intravenously injected with 7.4 MBq 32P. At the end of the experiment, the animals were slaughtered and samples of muscle (loin, heart, liver, kidney, and bones were collected. The supplementation in growing pigs can be reduced in 50% by adding 750UF/kg of diet in rations based in corn and soybean meal, balanced in agreement with concept of ideal protein, decreasing the P fecal excretion.

    Attention is paid to the atmosphere and how the understanding of its behavior could be facilitated by the observations and modeling of these interacting processes planned within the framework of the EOS (Earth Observing System) program. The Enrico Fermi School on which the book is based, was organized in such a way that general introductory lectures were followed by reviews of the planned EOS instruments and observational strategy to study specific components and processes in the earth atmosphere system. The contents are divided into four parts. Part 1 is an overview of the EOS concept and provides a general introduction to earth system science. Part 2 deals with the troposphere and includes a comprehensive introduction to the problems of tropospheric chemistry. The more traditional view of the troposphere as the stage for dynamics and meteorology is also dealt with. The climate system is discussed in detail in part 3, and includes the most important advances made in recent years in understanding some of these processes which have come from satellite observations. The final part deals with the middle atmosphere. The interest in ozone has made this region of the atmosphere the most closely studied in the last few years, in an attempt to establish how much of the changes in its composition may be attributable to natural variability and how much to anthropogenic influence

    Analysis of preoperative flexibility in adolescent idiopathic scoliosis (AIS) is essential to classify the curves, determine their structurality, and select the fusion levels during preoperative planning. Side-bending x-rays are the gold standard for the analysis of preoperative flexibility. The objective of this study was to examine the feasibility and performance of side-bending images taken in the standing position using the EOS imaging system. All patients who underwent preoperative assessment between April 2012 and January 2013 for AIS were prospectively included in the study. The work-up included standing AP and lateral EOS x-rays of the spine, standard side-bending x-rays in the supine position, and standing bending x-rays in the EOS booth. The irradiation dose was measured for each of the tests. Two-dimensional reducibility of the Cobb angle was measured on both types of bending x-rays. The results were based on the 50 patients in the study. No significant difference was demonstrated for reducibility of the Cobb angle between the standing side-bending images with the EOS imaging system and those in the supine position for all types of Lenke deformation. The irradiation dose was five times lower during the EOS bending imaging. The standing side-bending images in the EOS device contributed the same results as the supine images, with five times less irradiation. They should therefore be used in clinical routine. 2.

    The angular distribution of the 13 C(d,p) 14 C reaction is reanalysed using the Johnson-Soper approach. The squared asymptotic normalization coefficient (ANC) of virtual decay 14 C→ 13 C + n is then derived to be 21.4 ± 5.0 fm -1 . The squared ANC and spectroscopic factor (SF) of 14 O→ 13 N + p are extracted to be 30.4 ± 7.1 fm -1 and 1.94 ± 0.45, respectively. The astrophysical S-factors and reaction rates of 13 N(p, γ) 14 O are determined from the ANC of 14 O→ 13 N + p using the R-matrix approach. (authors)

    Full Text Available Resumo Foram desenvolvidas quatro formulações de pães, isentos de glúten e com a inclusão de fibra alimentar solúvel e insolúvel, avaliando suas propriedades físicas, composição química, aceitação e intenção de compra do consumidor. O padrão (1 teve a farinha de arroz, fécula de mandioca, ovo, leite em pó, óleo de girassol, sal, açúcar, fermento biológico seco e água como ingredientes. Nos demais, a fécula foi parcialmente substituída por inulina (2, farelo de arroz desengordurado e inulina (3, e farelo de arroz desengordurado (4. A cor do pão 2 diferiu apenas na casca, que ficou menos vermelha e amarela que o 1. A inclusão do farelo de arroz proporcionou coloração mais escura, vermelha e amarela à crosta e miolo dos pães 3 e 4. A perda de peso e rendimento variaram apenas em relação ao pão 2, que teve maior perda de peso e menor rendimento, provavelmente devido ao colapso da massa, que não foi capaz de manter a estrutura na fase de crescimento. O custo dos pães com inulina foi maior, pois este ingrediente é um reconhecido prebiótico, adquirido em estabelecimentos farmacêuticos; enquanto que o custo do pão apenas com farelo diminuiu, já que se trata de um subproduto industrial, obtido da extração do óleo de arroz. Na composição química, houve incremento nos teores de cinzas, proteínas e fibra alimentar, principalmente insolúvel, nos pães 3 e 4; enquanto que o pão 2 apresentou menor teor proteico e maior teor de fibra alimentar, principalmente solúvel. Nutricionalmente, admite-se incremento do valor nutricional em detrimento de carboidratos digeríveis e do valor calórico. Sensorialmente, os pães 3 e 4 tiveram menor aceitação nos atributos cor e sabor, mas não diferiram dos pães 1 e 2 nos atributos odor e textura, e na intenção de compra dos consumidores. Conclui-se que o consumo dos pães que tiveram substituição parcial da fécula é garantia de alimento com qualidade funcional

    This Contamination Control Plan is submitted in response the Contract Document requirements List (CDRL) 007 under contract NAS5-32314 for the Earth Observing System (EOS) Advanced Microwave Sounding Unit A (AMSU-A). In response to the CDRL instructions, this document defines the level of cleanliness and methods/procedures to be followed to achieve adequate cleanliness/contamination control, and defines the required approach to maintain cleanliness/contamination control through shipping, observatory integration, test, and flight. This plan is also applicable to the Meteorological Satellite (METSAT) except where requirements are identified as EOS-specific. This plan is based on two key factors: a. The EOS/METSAT AMSU-A Instruments are not highly contamination sensitive. b. Potential contamination of other EOS Instruments is a key concern as addressed in Section 9/0 of the Performance Assurance Requirements for EOS/METSAT Integrated Programs AMSU-A Instrument (MR) (NASA Specification S-480-79).

    We present three patients with overlapping interstitial deletions of 19p13.3 identified by high resolution SNP microarray analysis. All three had a similar phenotype characterized by intellectual disability or developmental delay, structural heart abnormalities, large head relative to height and weight or macrocephaly, and minor facial anomalies. Deletion sizes ranged from 792 Kb to 1.0 Mb and included a common region arr [hg19] 19p13.3 (3,814,392-4,136,989), containing eight genes: ZFR2, ATCAY, NMRK2, DAPK3, EEF2, PIAS4, ZBTB7A, MAP2K2, and two non-coding RNA's MIR637 and SNORDU37. The patient phenotypes were compared with three previous single patient reports with similar interstitial 19p13.3 deletions and six additional patients from the DECIPHER and ISCA databases to determine if a common haploinsufficient phenotype for the region can be established.

    2014-06-01

    Purpose: To estimate patient radiation dose for whole spine imaging using EOS, a new biplanar slot-scanning radiographic system and compare with standard scoliosis radiography. Methods: The EOS imaging system (EOS Imaging, Paris, France) consists of two orthogonal x-ray fan beams which simultaneously acquire frontal and lateral projection images of a standing patient. The patient entrance skin air kerma was measured for each projection image using manufacturer-recommended exposure parameters for spine imaging. Organ and effective doses were estimated using a commercially-available Monte Carlo simulation program (PCXMC, STUK, Radiation and Nuclear Safety Authority, Helsinki, Finland) for a 15 year old mathematical phantom model. These results were compared to organ and effective dose estimated for scoliosis radiography using computed radiography (CR) with standard exposure parameters obtained from a survey of pediatric radiographic projections. Results: The entrance skin air kerma for EOS was found to be 0.18 mGy and 0.33 mGy for posterior-anterior (PA) and lateral projections, respectively. This compares to 0.76 mGy and 1.4 mGy for CR, PA and lateral projections. Effective dose for EOS (PA and lateral projections combined) is 0.19 mSv compared to 0.51 mSv for CR. Conclusion: The EOS slot-scanning radiographic system allows for reduced patient radiation dose in scoliosis patients as compared to standard CR radiography.

    A short status update on the LOFAR Epoch of Reionization (EoR) Key Science Project (KSP) is given, regarding data acquisition, data processing and analysis, and current power-spectrum limits on the redshifted 21-cm signal of neutral hydrogen at redshifts z = 8 - 10. With caution, we present a preliminary astrophysical analysis of ~60 hr of processed LOFAR data and their resulting power spectrum, showing that potentially already interesting limits on X-ray heating during the Cosmic Dawn can already be gained. This is by no means the final analysis of this sub-set of data, but illustrates the future potential when all nearly 3000 hr of data in hand on two EoR windows will have been processed.

The discrimination of these two cryptic species using external characters and measures has proved to be somewhat problematic. We examined two colonies of soprano pipistrelle from Donji Miholjac, Croatia. As a result, only two characters proved to be of help for field identification: wing venation (89% of cases and penis morphology and colour for males. The difference in length between the 2nd and 3rd phalanxes of the 3rd finger should be discarded as diagnostic trait between <em>P. pipistrellusem> and <em>P. pygmaeusem> in Croatia.

    2015-12-01

    Purification of enough numbers of circulating eosinophils is difficult because eosinophils account for less than 5% peripheral blood leukocytes. Human eosinophilic leukemia EoL-1 cells have been considered an in vitro source of eosinophils as they can differentiate into mature eosinophil-like cells when incubated with dibutyryl cAMP (dbcAMP) or butyric acid. In this study, the viability and phenotypic maturation of EoL-1 cells stimulated by either dbcAMP or butyric acid were comparatively analyzed. After treatment with 100 µM dbcAMP or 0.5 µM butyric acid, EoL-1 cells showed morphological signs of differentiation, although the number of nonviable EoL-1 cells was significantly increased following butyric acid treatment. Stimulation of EoL-1 cells with 0.5 µM butyric acid more effectively induced the expression of mature eosinophil markers than stimulation with dbcAMP. These results suggest that treatment of EoL-1 cells with 0.5 µM butyric acid for limited duration could be an effective strategy for inducing their differentiation. Considering that expression of CCR3 was not sufficient in EoL-1 cells stimulated with 0.5 µM butyric acid, treatment of the chemically stimulated EoL-1 cells with cytokines, which primarily support eosinophil maturation, would help to obtain differentiated EoL-1 cells with greater functional maturity.

    2003-01-01

    The Earth Observing System (EOS) Aqua satellite was successfully launched on May 4,2002. Aqua is the second in the series of EOS satellites. EOS is part of NASA s Earth Science Enterprise Program, whose goals are to advance the scientific understanding of the Earth system. Aqua is a three-axis stabilized, Earth-pointing spacecraft in a nearly circular, sun-synchronous orbit at an altitude of 705 km. The Goddard Space Flight Center (GSFC) Flight Dynamics attitude team supported all phases of the launch and early mission. This paper presents the main results and lessons learned during this period, including: real-time attitude mode transition support, sensor calibration, onboard computer attitude validation, response to spacecraft emergencies, postlaunch attitude analyses, and anomaly resolution. In particular, Flight Dynamics support proved to be invaluable for successful Earth acquisition, fine-point mode transition, and recognition and correction of several anomalies, including support for the resolution of problems observed with the MODIS instrument.

    To investigate the efficacy and safety of switching from infliximab reference product (RP) to its biosimilar or maintaining biosimilar treatment in patients with ankylosing spondylitis (AS). This open-label extension study recruited patients with AS who completed a 54-week, randomised controlled study comparing CT-P13 with RP (PLANETAS). CT-P13 (5 mg/kg) was administered intravenously every 8 weeks from week 62 to week 102. Efficacy end points included the proportion of patients achieving Assessment of SpondyloArthritis international Society (ASAS)20. Antidrug antibodies (ADAs) were measured using an electrochemiluminescent method. Data were analysed for patients treated with CT-P13 in the main PLANETAS study and the extension (maintenance group) and those who were switched to CT-P13 during the extension study (switch group). Overall, 174 (82.9%) of 210 patients who completed the first 54 weeks of PLANETAS and agreed to participate in the extension were enrolled. Among these, 88 were maintained on CT-P13 and 86 were switched to CT-P13 from RP. In these maintenance and switch groups, respectively, ASAS20 response rates at week 102 were 80.7% and 76.9%. ASAS40 and ASAS partial remission were also similar between groups. ADA positivity rates were comparable (week 102: 23.3% vs 27.4%). Adverse events led to treatment discontinuation during the extension study in 3 (3.3%) and 4 (4.8%) patients, respectively. This is the first study to show that switching from RP to its biosimilar CT-P13 is possible without negative effects on safety or efficacy in patients with AS. In the maintenance group, CT-P13 was effective and well tolerated over 2 years of treatment. NCT01571206; Results. Published by the BMJ Publishing Group Limited.

    Highlights: • VLE data for (CH 4 (1) + C 6 H 6 (2)) and (CH 4 (1) + C 6 H 5 CH 3 (3)) were measured. • LLE was observed at T = 198.15 K, a T higher than expected, for (CH 4 + C 6 H 5 CH 3 ) . • Inconsistences in the literature data were identified and assessed. • More data at x 1 > 0.3 for both systems are needed to investigate discrepancies. - Abstract: New isothermal pTxy data are reported for (methane + benzene) and (methane + methylbenzene (toluene)) at pressures up to 13 MPa over the temperature range (188 to 313) K using a custom-built (vapor + liquid) equilibrium (VLE) apparatus. The aim of this work was to investigate literature data inconsistencies and to extend the measurements to lower temperatures. For (methane (1) + benzene (2)), measurements were made along six isotherms from (233 to 348) K at pressures to 9.6 MPa. At temperatures below 279 K there was evidence of a solid phase, and thus only vapor phase samples were analyzed at these temperatures. For the (methane (1) + methylbenzene (3)) system, measurements were made along seven isotherms from T = (188 to 313) K at pressures up to 13 MPa. Along the 198 K isotherm, a significant change in the data’s p,x slope was observed indicating (liquid + liquid) equilibria at higher pressures. The data were compared with literature data and with calculations made using the Peng–Robinson (PR) equation of state (EOS). For both binary systems our data agree with much of the literature data that also deviate from the EOS in a similar manner. However, the data of Elbishlawi and Spencer (1951) for both binary systems, which appear to have received an equal weighting to other data in the EOS development, are inconsistent with the results of our measurements and data from other literature sources

    The present study aims to develop a stable polymeric micellar formulation of curcumin (CM) with improved solubility and stability, and that is suitable for clinical applications in leukemia patients. CM-loaded polymeric micelles (CM-micelles) were prepared using poloxamers. The chemical structure of the polymers influenced micellar properties. The best formulation of CM-micelles, namely CM-P407, was obtained from poloxamer 407 at drug to polymer ratio of 1:30 and rehydrated with phosphate buffer solution pH 7.4. CM-P407 exhibited the smallest size of 30.3±1.3nm and highest entrapment efficiency of 88.4±4.1%. When stored at -80°C for 60days, CM-P407 retained high protection of CM and had no significant size change. In comparison with CM solution in dimethyl sulfoxide (CM-DMSO), CM kinetic degradation in both formulations followed a pseudo-first-order reaction, but the half-life of CM in CM-P407 was approx. 200 times longer than in CM-DMSO. Regarding the activity against FLT3 overexpressing EoL-1 leukemic cells, CM-P407 showed higher cytotoxicity than CM-DMSO. Moreover, intracellular uptake to leukemic cells of CM-P407 was 2-3 times greater than that of CM-DMSO. These promising results for CM-P407 will be further investigated in rodents and in clinical studies for leukemia treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

    Chromosome 5p13 duplication syndrome (OMIM #613174), a contiguous gene syndrome involving duplication of several genes on chromosome 5p13 including NIPBL (OMIM 608667), has been described in rare patients with developmental delay and learning disability, behavioral problems and peculiar facial dysmorphisms. 5p13 duplications described so far present with variable sizes, from 0.25 to 13.6 Mb, and contain a variable number of genes. Here we report another patient with 5p13 duplication syndrome including NIPBL gene only. Proband's phenotype overlapped that reported in patients with 5p13 microduplication syndrome and especially that of subjects with smaller duplications. Moreover, we better define genotype-phenotype relationship associated with this duplication and confirmed that NIPBL was likely the major dosage sensitive gene for the 5p13 microduplication phenotype.

    Full Text Available Resumo A farinha de banana verde (FBV é uma alternativa viável para o aproveitamento dos frutos e possui alto teor de amido resistente (AR, que apresenta papel fisiológico similar ao das fibras alimentares. O objetivo deste trabalho foi produzir FBV de dois genótipos de bananeira (Prata e Caturra, além de selecionar aquele com maior teor de AR, para posterior substituição de parte da farinha de trigo integral por FBV, em uma formulação de pão de fôrma integral. Para a produção das farinhas, os frutos foram descascados, cortados em rodelas e estas foram submersas em uma solução de ácido ascórbico e ácido cítrico, sendo então distribuídas em bandejas e secas a 50 °C, por 7 horas, e moídas. As farinhas foram submetidas às análises de composição proximal e determinação do teor de AR. Posteriormente, foram processados pães integrais com a substituição de 10%, 15% e 20% de farinha de trigo integral pela FBV que obteve o maior teor de AR. Os pães controle e aquele que apresentou maior teor de AR e boas características tecnológicas, como volume específico, dureza e cor, foram submetidos aos testes sensoriais de aceitação e intenção de compra. O teor de AR encontrado para as FBV Prata e Caturra foram 24,1% e 13,7%, respectivamente. O pão com substituição de 15% de farinha de trigo integral por FBV foi escolhido para a análise sensorial. As formulações controle e com 15% de FBV atingiram Índices de Aceitação Sensorial de 88,7% e 82,1%, respectivamente. A atitude dos avaliadores foi positiva, segundo a qual 56% dos avaliadores “comprariam frequentemente” ou “comprariam sempre” o pão com 15% de FBV, não tendo sido observada rejeição para nenhuma das formulações.

    THYDE-P1 is a code to analyze both the blowdown and refill-reflood phases of loss-of-coolant accidents (LOCAs) of pressurized water reactors (PWRs). Up to now, THYDE-P1 has been applied to various experiment analyses, which show its high capability to analyze LOCAs as a best estimate (BE) calculation code. In this report, evaluation model (EM) calculation method, especialy in the blowdown and refill phases, is established equivalently to WREM/J2 which is regarded as appropriate for an EM calculation code, and the results of them are compared and discussed. The present calculation was the first executed by THYDE-P1-EM, and was performed as Sample Calculation Run 80 which was a part of a series of THYDE-P sample calculations. The calculation was carried out from the LOCA initiation till 400 seconds for a guillotine break at the cold leg of a commercial 1,100 MWe PWR plant. The calculated results agreed well to that of the WREM/J2 code. (author)

    Full Text Available As parcerias público-privadas (PPPs tornaram-se, nas últimas décadas, uma moda em todo o mundo. Tendo em mente o pressuposto teórico das PPPs, analisa-se a relação entre a utilização destas e os resultados obtidos no setor da construção e gestão de rodovias em Portugal. Por meio de revisão teórica da literatura e da análise dos dados existentes, propõe-se discutir os aspetos positivos e negativos dessa experiência. Os resultados apontam acordos de construção e gestão das rodovias que, na prática, não resultaram em uma mais-valia para o Estado, porque contrariam as boas práticas na utilização dos recursos públicos.

    Full Text Available ResumoO objetivo deste artigo é analisar os problemas éticos gerados pelo padrão moderno-estressor de produtividade pós-transformações da reestruturação produtiva em saúde. Pesquisa qualitativa do tipo exploratório descritivo, em que foram entrevistados 30 profissionais [enfermeiros, médicos e cirurgiões-dentistas] de uma região metropolitana do sul do Brasil, com experiência de trabalho na área pública e privada. Os resultados seguiram a Análise Textual Discursiva. A capitalização é desvelada como importante problema ético na cadeia de novas questões advindas do imperativo produtividade-lucratividade em saúde, pela incorporação acrítica de uma ética restrita aos interesses da empresa ou corporativo-individuais. O problema ético do baixo comprometimento profissional às necessidades do paciente e coletivo social indica a necessidade de construção de uma nova solidariedade engajada para aumento da qualidade no atendimento público. Uma produtividade voltada ao cuidado às necessidades/interesses individuais e sociais em saúde solicita um novo engajamento autogestor e coletivo dos sujeitos, apoiado num esforço institucional e ético-político de grupalidade, cooperação e solidariedade.

OBJETIVO: Nosso objetivo foi estudar o comportamento da CPR e seus mecanismos subjacentes em camundongos com infarto do miocárdio. MÉTODOS: Seis semanas após a oclusão coronariana, a contratilidade dos Músculos Papilares (MP obtidos a partir de camundongos submetidos à cirurgia sham (C, n = 17, com infarto moderado (MMI, n = 10 e grande infarto (LMI, n = 14, foi avaliada após intervalos de repouso de 10 a 60 segundos antes e depois da incubação com cloreto de lítio (Li+ em substituição ao cloreto de sódio ou rianodina (Ry. A expressão proteica de SR Ca(2+-ATPase (SERCA2, trocador Na+/Ca2+ (NCX, fosfolambam (PLB e fosfo-Ser (16-PLB foi analisada por Western blotting. RESULTADOS: Os camundongos MMI apresentaram potenciação de CPR reduzida em comparação aos camundongos C. Em oposição à potenciação normal para camundongos C, foram observadas degradações de força pós-repouso nos músculos de camundongos LMI. Além disso, a Ry bloqueou a degradação ou potenciação de PRC observada em camundongos LMI e C; o Li+ inibiu o NCX e converteu a degradação em potenciação de CPR em camundongos LMI. Embora os camundongos MMI e LMI tenham apresentado diminuição no SERCA2 (72 ± 7% e 47 ± 9% de camundongos controle, respectivamente e expressão protéica de fosfo-Ser16-PLB (75 ± 5% e 46 ± 11%, respectivamente, a superexpressão do NCX (175 ± 20% só foi observada nos músculos de camundongos LMI. CONCLUSÃO: Nossos resultados mostraram, pela primeira vez, que a remodelação miocárdica pós-IAM em camundongos pode mudar a potenciação regular para degradação pós-repouso, afetando as proteínas de manipulação de Ca(2+ em miócitos.

    We study 22 children with clinical symptoms of gastroesophageal reflux. The main manifestations were: frequent vomiting, failure to thrive and repetitive pneumonia. In all of them we perform barium esophagogram (SEGD) with fluoroscopy, esophageal manometry (EM) and a four hours intraesophageal pH measurement. Thirteen of the twenty two children present a pathologic reflux (ERGE); in 16 we found SEGD that show reflux; three of them had an abnormal EM, the other 13 were normal. Seven patients showed alteration of the intraesophageal pH measurement. In conclusion the intraesophageal pH measurement in short period of time (4 hours) is a good method in the diagnosis of patients with ERGE.

    EOS is an open source distributed disk storage system in production since 2011 at CERN. Development focus has been on low-latency analysis use cases for LHC(1) and non- LHC experiments and life-cycle management using JBOD(2) hardware for multi PB storage installations. The EOS design implies a split of hot and cold storage and introduced a change of the traditional HSM(3) functionality based workflows at CERN.The 2015 deployment brings storage at CERN to a new scale and foresees to breach 100 PB of disk storage in a distributed environment using tens of thousands of (heterogeneous) hard drives. EOS has brought to CERN major improvements compared to past storage solutions by allowing quick changes in the quality of service of the storage pools. This allows the data centre to quickly meet the changing performance and reliability requirements of the LHC experiments with minimal data movements and dynamic reconfiguration. For example, the software stack has met the specific needs of the dual computing centre set-...

    The structure of crystals of molybdenyl tetrapolyphosphate [MoO] 2 P 4 O 13 has been determined. The substance is crystallized in the monoclinic syngony with the following parameters of the elementary cell: a=8.288 (2); b=10.690 (3); c=19.529 (5) A; γ=106.7 (3) deg. The structural units are molybdenyl groups MoO(3 + ) and polyphosphate anions P 4 O 13 (6 - ) that are composed of four PO 4 tetrahedrons whose apexes are connected in series. Three atoms of phasphate anion form the ''internal'' P-O-P bridges, while the remaining oxygen atoms, the ''external'' P-O-Mo bridges. The optimum temperature of crystals synthesis is 450 - 460 deg C. A mixture of phase of MoO 2 P 4 O 13 and Mo(PO 3 ) 3 is obtained as temperature is raised up to 600 deg C. Consequently, the stepwise dissociation of molybdenyl ions with the splitting off of oxygen and gradual reduction in the degree of molybdenum oxidation (MoO 2 ) 2+ → (MoO) 3+ → Mo 3+ occurs in the solution

    To investigate the psychometric properties of the Greek 13-item measure of patients' satisfaction (FAMCARE-P13) in palliative care setting. A hundred patients completed the FAMCARE-P13. Exploratory factor analysis and confirmatory factor analysis (CFA) have been conducted. Two factors' solution was revealed from CFA. The questionnaire was administered to an initial validation sample and then for test-retest in a sample of 40 patients 3 days later. The Rosenberg Self-Esteem Scale measuring global self-esteem has been also used as a gold standard for construct validity. Subscale and known groups validity have also been tested for FAMCARE-P13s' validity. A reduced 13-item version of our measure (FAMCARE-P13) possessed 2-factor structure with high reliability. Patient satisfaction was correlated with physical distress, communication and relationship with health-care providers, and caregiver satisfaction. We recommend the use of the Greek FAMCARE-P13 to assess care satisfaction of patients with advanced-stage cancer.

A harpina e, em menor grau, o ASM proporcionaram aumento da atividade da enzima peroxidase e a consequente redução da área lesionada e da esporulação de C. gloeosporioides nas maçãs. Esses eliciadores podem ser utilizados como ferramenta de controle no manejo integrado da podridão‑amarga, em pós‑colheita de maçãs 'Royal Gala'.

    Full Text Available INTRODUÇÃO: A carcinogênese caracteriza-se como um processo multifatorial, e a inativação da proteína p53 é uma alteração genética comumente observada nos carcinomas de células escamosas de boca (CCEB. OBJETIVO: Analisar e comparar a imunoexpressão da proteína p53, por meio dos clones DO-7 e PAb-240, em CCEB com localização intrabucal e em lábio inferior. MATERIAL E MÉTODOS: Foram selecionados 40 casos de CCEB, sendo 20 de localização intrabucal e 20 em lábio inferior. Foi realizado um estudo imuno-histoquímico utilizando os anticorpos anti-p53 clone DO-7 e PAb-240. A imunoquantificação foi realizada por meio de análise digital de imagem, e os resultados, submetidos a tratamentos estatísticos. RESULTADOS: A imunoexpressão da proteína p53 foi verificada com o anticorpo DO-7 em 13 casos (65% de carcinoma intrabucal e em 19 (95% de carcinoma de lábio inferior. Imunorreatividade para o anticorpo PAb-240 foi observada em 9 casos (45% de lesões intrabucais e em 15 (75% localizados em lábio inferior. Não foram observadas, segundo o teste de Mann-Whitney, diferenças estatisticamente significativas (p > 0,05 na expressão da proteína p53 entre as duas localizações estudadas, independentemente do anticorpo avaliado. Foram identificadas, pelo teste de Wilcoxon, diferenças estatisticamente significativas entre a expressão dos clones DO-7 e PAb-240 em cada um dos grupos analisados (valor p = 0,013 - lábio inferior; valor p = 0,016 - intrabucal. CONCLUSÕES: A expressão da proteína p53 observada nos CCEB, com localizações intrabucais e labiais, sugere a ocorrência de mutações no gene TP53. As diferenças quantitativas obtidas entre os anticorpos estudados, independentemente da localização das lesões, refletem uma especificidade distinta entre os clones DO-7 e PAb-240. O desenvolvimento de mais estudos será fundamental para estabelecer o anticorpo mais adequado para proteína p53 em CCEB

    Full Text Available Este estudo pretende investigar de que forma a Educação Superior pública se configura atualmente, levando em consideração a relação que há entre as esferas públicas e as esferas privadas em nossa sociedade. Para tanto, utilizaremos o materialismo histórico e dialético como método, em uma perspectiva para além da compreensão, mas de ação para a superação dessa realidade. Com isso, buscamos entender de que forma o Brasil está inserido na ordem mundial capitalista, que, de acordo com Autor e Autor, é de forma dependente e periférica e a maneira que isso se materializa em nossas relações sociais, neste caso, as políticas educacionais. Nesse sentido, discutir as relações entre o público e o privado na educação pública torna-se imperioso, porquanto vemos ataques cada vez maiores por parte do capital aos serviços públicos, utilizando-se do Estado, e da educação, como trincheiras avançadas no processo da luta de classes.

No processo de coagulação/floculação foram avaliados o pH (4 a 8 e a concentração de cloreto férrico (100 a 600 mg L-1. No processo de adsorção em CAP, foram avaliadas as concentrações de 0,1-5,0 g L-1 de CAP, e na reação com Fenton, foram avaliadas as relações DQO:H2O2 [1:0,5, 1:1, 1:2 e 1:5], além das relações Fe:H2O2 [1:3, 1:5 e 1:10]. Nas melhores condições obtidas, foi avaliada a biodegradabilidade aeróbia dos efluentes tratados pelo método de Zahn-Wellens. O resultado do processo de coagulação/floculação foi de 22,9% de remoção da DQO e 64% de COT, utilizando 300 mg L-1 de coagulante em pH 4. Na adsorção em CAP, foram obtidas remoções de 69% da DQO, utilizando 5 g L-1 de carvão. Na reação de Fenton, foram alcançadas remoções de 82,3% de DQO (para DQO:H2O2=1:2 e Fe:H2O2 =1:3. Os resultados de biodegradabilidade aeróbia mostraram que apenas o lixiviado tratado com Fenton apresentou uma biodegradabilidade de 12 pontos percentuais maior em relação ao bruto, mostrando a sua potencialidade como pré tratamento ao processo biológico.

    Full Text Available O objetivo deste trabalho foi caracterizar e comparar o dimensionamento de recursos humanos dos Serviços de Alimentação e Nutrição Hospitalar (SANH e a qualificação do corpo técnico de nutricionistas da rede hospitalar pública e privada. Foram estudados 27 hospitais, 17 de Campinas e 10 de Ribeirão Preto, por meio de um questionário estruturado aplicado aos coordenadores do SANH, que abordou: condições de trabalho, pela relação entre número de leitos por nutricionista e por profissionais do SANH, e pelo número de refeições produzidas por leito, por nutricionistas e por funcionários do SANH; a formação acadêmica; e a experiência profissional dos nutricionistas. Foram encontradas diferenças significativas na relação número de leitos/nutricionista entre hospitais públicos (38,2 dp 11,4 e privados (94,6 dp 46,4 e de funcionários do SANH/nutricionista (11,4 dp 4,9 e 23,8 dp 13,3. A produção de refeições por leitos foi maior nos hospitais públicos (p=0,04. No setor público concentram-se nutricionistas com capacitação stricto sensu, mesmo que ainda em um número reduzido em relação ao encontrado no país; e, no privado, há mais profissionais com formação lato sensu. Uma ampla heterogeneidade no dimensionamento de recursos humanos do SANH em hospitais públicos e privados foi encontrada; contudo, o setor público apresentou condição mais favorável em alguns indicadores, mesmo estando aquém das necessidades, principalmente na área de atenção nutricional ao paciente hospitalizado. Os resultados apontam para a necessidade de se constituirem indicadores específicos de recursos humanos nos SANHs, para o desempenho de ações na área de produção de refeições e de cuidado nutricional ao paciente hospitalizado. Criar mecanismos de capacitação do nutricionista para as áreas de competência da nutrição hospitalar poderia contribuir com o aprimoramento do setor.

Método: foram analisadas todas as teleconsultorias consecutivas de fonoaudiologia realizadas de fevereiro de 2011 a maio de 2014. As teleconsultorias foram agrupadas de acordo com tipo de dúvida, profissional solicitante e área de atuação fonoaudiológica. Resultados: as 259 teleconsultorias realizadas no período do estudo foram originadas de 81 municípios. A maior demanda de teleconsultorias foi dos próprios fonoaudiólogos (64,5%, seguidos de enfermeiros (27,0% e médicos (5,0%. A maior parte das dúvidas eram assistenciais (81%, sendo que, destas, 35% eram para auxílio na definição diagnóstica e 65% para discussão de procedimentos e sugestão de condutas terapêuticas. Esta proporção foi semelhante, independente da formação do profissional solicitante: fonoaudiólogo e não fonoaudiólogo (65,7% vs. 64,9%, p=1,00. A maioria das dúvidas estava relacionada à área da linguagem (47% e à motricidade oral (29%, seguidas de voz (20%, audiologia (18%, disfagia (10% e saúde pública (3%. Conclusão: neste estudo, foi observado que a maioria das dúvidas para o serviço de teleconsultorias em fonoaudiologia estavam relacionadas à área da linguagem, mas há demanda em todas as áreas de abrangência da profissão. Embora o uso da teleconsultoria em fonoaudiologia seja ainda incipiente, observa-se grande potencial de utilização deste instrumento na prática clínica.

    The Earth Observing One (EO-1) satellite is a technology demonstration mission that was launched in November 2000, and by July 2012 will have successfully completed almost 12 years of high spatial resolution (30 m) imaging operations from a low Earth orbit. EO-1 has two unique instruments, the Hyperion and the Advanced Land Imager (ALI). Both instruments have served as prototypes for NASA's newer satellite missions, including the forthcoming (in early 2013) Landsat-8 and the future Hyperspectral Infrared Imager (HyspIRI). As well, EO-1 is a heritage platform for the upcoming German satellite, EnMAP (2015). Here, we provide an overview of the mission, and highlight the capabilities of the Hyperion for support of science investigations, and present prototype products developed with Hyperion imagery for the HyspIRI and other space-borne spectrometers.

  1. Technical advances in neutron polarimetry and studies of the (p,n) reaction in /sup 13/C

    Videla, N G

    1985-01-01

    The asymmetry in the /sup 4/He(p,n vector)/sup 4/He reaction has been measured at three different incident neutron energies: 19.40; 22.85 and 27.31 MeV, and 120/sup 0/ from forward direction. Values of the asymmetry have been used to calculate the polarization of fast neutrons produced in the /sup 13/C(p,n vector)/sup 13/N. The /sup 13/C(p,n vector)/sup 13/N reaction was studied as part of a program being undertaken at the University of Manitoba Cyclotron Laboratory to study (p,n) reactions linking isobaric analog states of mirror nuclei in the energy range of 22 to 50 MeV. The study involves a comparison of the proton analyzing power A(theta), in the reaction /sup 13/C(vector p,n)/sup 13/N to the neutron polarization in the inverse reaction /sup 13/C(p,n vector)/sup 13/N. The importance of the comparison between these two observables is based in Conzett's theorem for time reversed reactions, the theorem states that the proton analyzing power in the reaction /sup 13/C(vector p,n)/sup 13/N is equal to the neutron polarization in the reaction /sup 13/C(p,n vector)/sup 13/N provided the reaction proceeds between members of an isospin doublet and when charge symmetry and time reversal invariance hold exactly. However, isospin symmetry is broken by the Coulomb interaction. So comparison of these two observables should yield information of the breaking of isospin by the Coulomb force.

    This study used neutron diffraction to investigate a ceramide-[NP] C24/[AP] C24 /[EOS]-br C30/cholesterol/lignoceric acid (0.6: 0.3: 0.1: 0.7: 1) based stratum corneum modelling system. By adding specifically deuterated ceramides-[NP]-D 3 , [AP]-D 3 , and [EOS]-br-D 3 , detailed information on the lamellar and the nanostructure of the system was obtained. For the short periodicity phase a natural-like lamellar repeat distance of 5.47 ± 0.02 nm was observed, similar to the [NP]/[AP] base system without the [EOS]-br. Unlike in this system the ceramides here were slightly tilted, hinting towards a slightly less natural arrangement. Due to the deuteration it was possible to observe that the long ceramide chains were overlapping in the lamellar mid-plane. This is considered to be an important feature for the natural stratum corneum. Despite the presence of a ceramide [EOS] analogue - able to form a long phase arrangement - no distinct long periodicity phase was formed, despite a slightly higher than natural ω-acyl ceramide ratio of 10 mol%. The deuterated variant of this ceramide determined that the very long ceramide was integrated into the short periodicity phase, spanning multiple layers instead. The - compared to the base system - unchanged repeat distance highlights the stability of this structure. Furthermore, the localisation of the very long ceramide in the short periodicity phase indicates the possibility of a crosslinking effect and thus a multilayer stabilizing role for the ceramide [EOS]. It can be concluded, that additionally to the mere presence of ceramide-[EOS] more complex conditions have to be met in order to form this long phase. This has to be further investigated in the future. Copyright © 2018 Elsevier B.V. All rights reserved.

    With current efforts inching closer to detecting the 21-cm signal from the Epoch of Reionization (EoR), proper preparation will require publicly available simulated models of the various forms the signal could take. In this work we present a database of such models, available at 21ssd.obspm.fr. The models are created with a fully-coupled radiative hydrodynamic simulation (LICORICE), and are created at high resolution (10243). We also begin to analyse and explore the possible 21-cm EoR signals (with Power Spectra and Pixel Distribution Functions), and study the effects of thermal noise on our ability to recover the signal out to high redshifts. Finally, we begin to explore the concepts of `distance' between different models, which represents a crucial step towards optimising parameter space sampling, training neural networks, and finally extracting parameter values from observations.

    The Earth Observing One (EO-1) satellite was launched in November 2000 as a one year technology demonstration mission for a variety of space technologies. After the first year, in addition to collecting science data from its instruments, the EO-1 mission has been used as a testbed for a variety of technologies which provide various automation capabilities and which have been used as a pathfinder for the creation of SensorWebs. A SensorWeb is the integration of variety of space, airborne and ground sensors into a loosely coupled collaborative sensor system that automatically provides useful data products. Typically, a SensorWeb is comprised of heterogeneous sensors tied together with a messaging architecture and web services. This paper provides an overview of the various technologies that were tested and eventually folded into normal operations. As these technologies were folded in, the nature of operations transformed. The SensorWeb software enables easy connectivity for collaboration with sensors, but the side benefit is that it improved the EO-1 operational efficiency. This paper presents the various phases of EO-1 operation over the past 12 years and also presents operational efficiency gains demonstrated by some metrics.

    The components of the essential oils (EOs) obtained by solvent-free microwave extraction (SFME) and hydrodistillation (HD) from endemic Origanum saccatum P.H. Davis were identified by using GC/MS. The main constituents of both EOs obtained by SFME and HD, respectively, from O. saccatum were p-cymene (72.5 and 70.6%), thymol (9.32 and 8.11%), and carvacrol (7.18 and 6.36%). The EO obtained by SFME contained substantially higher amounts of oxygenated compounds and lower amounts of monoterpenes than did the EO obtained by HD. The antibacterial activities of the EOs obtained by SFME and HD were evaluated with the disc diffusion method by comparison with 10 different bacterial strains. The antibacterial activity of the EO extracted by SFME was found to be more effective than that of the EO extracted by HD against seven of the tested bacteria.

    In recent years, operations executed by naval forces have taken place at many different locations. At present, operations against international terrorism and asymmetric warfare in coastal environments are of major concern. In these scenarios, the threat caused by pirates on-board of small surface targets, such as jetskis and fast inshore attack crafts, is increasing. In the littoral environment, the understanding of its complexity and the efficient use of the limited reaction time, are essential for successful operations. Present-day electro-optical sensor suites, also incorporating Infrared Search and Track systems, can be used for varying tasks as detection, classification and identification. By means of passive electro-optical systems, infrared and visible light sensors, improved situational awareness can be achieved. For long range capability, elevated sensor masts and flying platforms are ideally suited for the surveillance task and improve situational awareness. A primary issue is how to incorporate new electro-optical technology and signal processing into the new sensor concepts, to improve system performance. It is essential to derive accurate information from the high spatial-resolution imagery created by the EO sensors. As electro-optical sensors do not have all-weather capability, the performance degradation in adverse scenarios must be understood, in order to support the operational use of adaptive sensor management techniques. In this paper we discuss the approach taken at TNO in the design and assessment of system concepts for future IRST development. An overview of our maritime programme in future IRST and EO system concepts including signal processing is presented.

    Recently measured anomalously low cross sections for 13 C(γ,π - ) 13 N at low energy and theta sub(π)sup(lab) = 90 degrees have been analyzed in a DWIA calculation. It has been found that the EO contribution alone is able to explain the data, so that the MI cross section is expected to vanish. Using constraints from recent magnetic electron scattering, an explanation is possible by assuming a significantly lower reduced density matrix element for spin-flip isovector transitions with angular momentum L = 2 than predicted by Cohen-Kurath

    Full Text Available As ressecções intestinais em países desenvolvidos ocorrem devido às malformações congênitas. Em países em desenvolvimento essas resseções ocorrem por causas potencialmente evitáveis, como invaginação intestinal irredutível, trauma abdominal fechado, volvo de jejuno-íleo, enterocolite necrosante, hérnia inguinal estrangulada e obstrução por bridas pós-operatórias. O volvo intestinal na infância é raro e geralmente de causas iatrogênicas causado, por exemplo, pela presença de grampos soltos a cavidade intestinal após apendicectomia laparoscópica. O volvo de jejuno-íleo pode ser secundário à isquemia nos casos de gastrosquise tratadas com silo ou mesmo pela colocação de banda gástrica pós-laparoscopia, ou ainda pela presença de lipoma mesentérico. Não foi identificado trabalho na literatura recente sobre volvo jejuno-íleo e isquemia e necrose de segmento de alça intestinal.

    The deleptonization and cooling times of a newly born neutron star depend on the equation of state (EOS) and neutrino opacities in dense matter. Through model calculations we show that effects of Pauli blocking and many-body correlations due to strong interactions reduce both the neutral and charged current neutrino cross sections by large factors compared to the case in which these effects are ignored.

    The University of New Hampshire (UNH) has developed a Web-based tool that makes data, information, products, and services concerning terrestrial ecological and hydrological processes available to the Earth Science community. Our WEB-based System for Terrestrial Ecosystem Research (EOS-WEBSTER) provides a GIS-oriented interface to select, subset, reformat and download three main types of data: selected NASA Earth Observing System (EOS) remotely sensed data products, results from a suite of ecosystem and hydrological models, and geographic reference data. The Large Scale Biosphere-Atmosphere Experiment in Amazonia Project (LBA) has implemented a search engine, Beija-flor, that provides a centralized access point to data sets acquired for and produced by LBA researchers. The metadata in the Beija-flor index describe the content of the data sets and contain links to data distributed around the world. The query system returns a list of data sets that meet the search criteria of the user. A common problem when a user of a system like Beija-flor wants data products located within another system is that users are required to re-specify information, such as spatial coordinates, in the other system. This poster describes methodology by which Beija-flor generates a unique URL containing the requested search parameters and passes the information to EOS-WEBSTER, thus making the interactive services and large diverse data holdings in EOS-WEBSTER directly available to Beija-flor users. This "Calling Card" is used by EOS-WEBSTER to generate on-demand custom products tailored to each Beija-flor request. Through a collaborative effort, we have demonstrated the ability to integrate project-specific search engines such as Beija-flor with the products and services of large data systems such as EOS-WEBSTER, to provide very specific information products with a minimal amount of additional programming. This methodology has the potential to greatly facilitate research data exchange by

    Full Text Available BACKGROUND: The issue of whether patients diagnosed with metastatic colorectal cancer who harbor KRAS codon 13 mutations could benefit from the addition of anti-epidermal growth factor receptor therapy remains under debate. The aim of the current study was to perform computational analysis to investigate the structural implications of the underlying mutations caused by c.38G>A (p.G13D on protein conformation. METHODS: Molecular dynamics (MD simulations were performed to understand the plausible structural and dynamical implications caused by c.35G>A (p.G12D and c.38G>A (p.G13D. The potential of mean force (PMF simulations were carried out to determine the free energy profiles of the binding processes of GTP interacting with wild-type (WT KRAS and its mutants (MT. RESULTS: Using MD simulations, we observed that the root mean square deviation (RMSD increased as a function of time for the MT c.35G>A (p.G12D and MT c.38G>A (p.G13D when compared with the WT. We also observed that the GTP-binding pocket in the c.35G>A (p.G12D mutant is more open than that of the WT and the c.38G>A (p.G13D proteins. Intriguingly, the analysis of atomic fluctuations and free energy profiles revealed that the mutation of c.35G>A (p.G12D may induce additional fluctuations in the sensitive sites (P-loop, switch I and II regions. Such fluctuations may promote instability in these protein regions and hamper GTP binding. CONCLUSIONS: Taken together with the results obtained from MD and PMF simulations, the present findings implicate fluctuations at the sensitive sites (P-loop, switch I and II regions. Our findings revealed that KRAS mutations in codon 13 have similar behavior as KRAS WT. To gain a better insight into why patients with metastatic colorectal cancer (mCRC and the KRAS c.38G>A (p.G13D mutation appear to benefit from anti-EGFR therapy, the role of the KRAS c.38G>A (p.G13D mutation in mCRC needs to be further investigated.

    Full Text Available Girinimbine, a carbazole alkaloid isolated from the stem bark of <em>Murraya koenigii em>was tested for the<em> in vitroem> anti-tumour promoting and antioxidant activities. Anti-tumour promoting activity was determined by assaying the capability of this compound to inhibit the expression of early antigen of Epstein-Barr virus (EA-EBV in Raji cells that was induced by the tumour promoter, phorbol 12-myristate 13-acetate. The concentration of this compound that gave an inhibition rate at fifty percent was 6.0 µg/mL and was not cytotoxic to the cells. Immunoblotting analysis of the expression of EA-EBV showed that girinimbine was able to suppress restricted early antigen (EA-R. However, diffused early antigen (EA-D was partially suppressed when used at 32.0 µg/mL.

    Cohen, S.M.

    1987-01-01

    The metabolism of 13 C-labeled substrates was followed by 13 C and 31 P NMR in perfused liver from the streptozotocin-treated rat model of insulin-dependent diabetes. Comparison was made with perfused liver from untreated littermates, fasted either 24 or 12 h. The major routes of pyruvate metabolism were followed by a 13 C NMR approach that provided for the determination of the metabolic fate of several substances simultaneously. The rate of gluconeogenesis was 2-4-fold greater and β-hydroxybutyrate production was 50% greater in liver from the chronically diabetic rats as compared with the control groups. Large differences in the distribution of 13 C label in hepatic alanine were measured between diabetic and control groups. The biosyntheses of 13 C-labeled glutathione and N-carbamoylaspartate were monitored in time-resolved 13 C NMR spectra of perfused liver. Assignments for the resonances of glutathione and N-carbamoylaspartate were made with the aid of 13 C NMR studies of perchloric acid extracts of the freeze-clamped livers. 13 C NMR spectroscopy of the perfusates provided a convenient, rapid assay of the rate of oxidation of [2- 13 C]ethanol, the hepatic output of [2- 13 ]acetaldehyde, and the accumulation of [2- 13 C]acetate in the perfusate. By 31 P NMR spectroscopy, carbamoyl phosphate was measured in all diabetic livers and an unusual P,P'-diesterified pyrophosphate was observed in one-fourth of the diabetic livers examined. Neither of these phosphorylated metabolites was detected in control liver. Both 13 C and 31 P NMR were useful in defining changes in hepatic metabolism in experimental diabetes

    2012-06-01

    Full Text Available CV_2116 is a small hypothetical protein of 82 amino acids from the Gram-negative coccobacillus <em>Chromobacterium violaceumem>. A PSI-BLAST search using the CV_2116 sequence as a query identified only one hit (E = 2e−07 corresponding to a hypothetical protein OR16_04617 from <em>Cupriavidus basilensisem> OR16, which failed to provide insight into the function of CV_2116. The <em>CV_2116em> gene was cloned into the p15TvLic expression plasmid, transformed into <em>E. coliem>, and 13C- and 15N-labeled NMR samples of CV_2116 were overexpressed in <em>E. coliem> and purified for structure determination using NMR spectroscopy. The resulting high-quality solution NMR structure of CV_2116 revealed a novel α + β fold containing two anti-parallel β -sheets in the <em>N>-terminal two-thirds of the protein and one α-helix in the <em>C>-terminal third of the protein. CV_2116 does not belong to any known protein sequence family and a Dali search indicated that no similar structures exist in the protein data bank. Although no function of CV_2116 could be derived from either sequence or structural similarity searches, the neighboring genes of <em>CV_2116em> encode various proteins annotated as similar to bacteriophage tail assembly proteins. Interestingly, <em>C. violaceumem> exhibits an extensive network of bacteriophage tail-like structures that likely result from lateral gene transfer by incorporation of viral DNA into its genome (prophages due to bacteriophage infection. Indeed, <em>C. violaceumem> has been shown to contain four prophage elements and <em>CV_2116em> resides in the fourth of these elements. Analysis of the putative operon in which CV_2116 resides indicates that CV_2116 might be a component of the bacteriophage tail-like assembly that occurs in <em>C. violaceumem>.

    2012-10-01

    Full Text Available Este artigo traça um panorama crítico da emergência dos novos movimentos de protesto (NMP em França, nas últimas décadas. Argumenta-se que desde meados dos anos oitenta, novas arenas públicas foram abertas pelos NMP, seguindo as transformações da sociedade salarial e da política pública, e respondendo à mundialização crescente dos mecanismos económicos, estratégicos e sociais. Para quem investe politicamente nos NMP, a importância da sua emergência reside no rearmamento da crítica social e na reconstituição de uma esquerda radical. Novos problemas públicos se impuseram aos cidadãos, aos especialistas e aos decisores políticos, em particular em torno da questão dos “sem documentos”, dos “sem trabalho” e dos “sem abrigo” mas também da saúde pública, da ecologia ou do consumo. Novos actores colectivos, ONGs, movimentos e coordenações tornaram-se os parceiros e os adversários incontornáveis dos poderes públicos. Contudo, alerta-se para o perigo destes movimentos resvalarem para uma acção político-partidária institucional, que poria em causa a acção concertada da esquerda política e a eficácia da sua actuação quer no contexto nacional quer no contexto europeu.

  10. Evaluation of software based redundancy algorithms for the EOS storage system at CERN

    International Nuclear Information System (INIS)

    2012-01-01

    EOS is a new disk based storage system used in production at CERN since autumn 2011. It is implemented using the plug-in architecture of the XRootD software framework and allows remote file access via XRootD protocol or POSIX-like file access via FUSE mounting. EOS was designed to fulfill specific requirements of disk storage scalability and IO scheduling performance for LHC analysis use cases. This is achieved by following a strategy of decoupling disk and tape storage as individual storage systems. A key point of the EOS design is to provide high availability and redundancy of files via a software implementation which uses disk-only storage systems without hardware RAID arrays. All this is aimed at reducing the overall cost of the system and also simplifying the operational procedures. This paper presents the advantages and disadvantages of redundancy by hardware (most classical storage installations) in comparison to redundancy by software. The latter is implemented in the EOS system and achieves its goal by spawning data and parity stripes via remote file access over nodes. The gain in redundancy and reliability comes with a trade-off in the following areas: • Increased complexity of the network connectivity • CPU intensive parity computations during file creation and recovery • Performance loss through remote disk coupling An evaluation and performance figures of several redundancy algorithms are presented for dual parity RAID and Reed-Solomon codecs. Moreover, the characteristics and applicability of these algorithms are discussed in the context of reliable data storage systems.

    Single nucleotide polymorphisms (SNPs) in loci 1p13 and 9p21 have previously been found to be associated with incident coronary heart disease (CHD). This study aimed to investigate whether these SNPs show associations with fatal CHD in a population-based cohort study after adjustment for socioeconomic- and lifestyle-related CHD risk factors not commonly included in genetic association studies. Using the population-based Cohort of Norway (CONOR), a nested case-cohort study was set up and DNA from 2,953 subjects (829 cases and 2,124 non-cases) were genotyped. The association with fatal CHD was estimated for four SNPs, three from locus 1p13 and one from locus 9p21. Multivariable Cox regression was used to estimate unstratified and gender-stratified hazard ratios while adjusting for major CHD risk factors. The associations between three SNPs from locus 1p13 and non-HDL cholesterol levels were also estimated. Men homozygous for the risk alleles on rs1333049 (9p21) and rs14000 (1p13) were found to have significantly increased hazard ratios in crude and adjusted models, and the hazard ratios remained statistically significant when both genders were analyzed together. Adjustment for additional socioeconomic- and lifestyle-related CHD risk factors influenced the association estimates only slightly. No significant associations were observed between the other two SNPs in loci 1p13 (rs599839 and rs646776) and CHD mortality in either gender. Both rs599839 and rs646776 showed significant, gradual increases in non-HDL cholesterol levels with increasing number of risk alleles. This study confirms the association between 9p21 (rs1333049) and fatal CHD in a Norwegian population-based cohort. The effect was not influenced by several socioeconomic- and lifestyle-related risk factors. Our results show that 1p13 (rs14000) may also be associated with fatal CHD. SNPs at 1p13 (rs599839 and rs646776) were associated with non-HDL cholesterol levels.

    Chromosomal duplications involving 17p13.3 have recently been defined as a new distinctive syndrome with several diagnosed patients. Some variation is known to occur in the breakpoints of the duplicated region and, consequently, in the phenotype as well. We report on a patient, the fifth to our knowledge, a 4-year-old girl with a pure de novo subtelomeric 17p13.2-pter duplication. She presents all of the facial features described so far for this duplication and in addition, a unilateral palmar transversal crease and oculocutaneous albinism which has not been reported previously. A detailed molecular description of the reported aberration and correlation with the observed phenotypical features based on a literature review. We discuss the possible molecular etiology of albinism in regard to the mode of inheritance. The new data provided here may be useful for further genotype correlations in syndromes with oculocutaneous albinism, especially of autosomal dominant inheritance.

    A single crystal of the compound Sr 3 P 4 O 13 has been found and the crystal structure has been characterized by means of single crystal X-ray diffraction analysis. The compound crystallizes in triclinic system and belongs to space group P1-bar. It builds up from SrO 7 polyhedra and P 4 O 13 -6 anions and has a layered structure, and the Sr atoms are located in the interlayer space. The absorption and luminescence spectrum of Sr 3 P 4 O 13 microcrystals have been measured. The calculated results of crystal energy band structure by the DFT show that the solid state of Sr 3 P 4 O 13 is an isolator with direct band gap. The calculated total and partial density of states indicate that the top valence bands are contributions from P 3p and O 2p states and low conduction bands mostly originate from Sr atomic states. The calculated optical response functions expect that the Sr 3 P 4 O 13 is a low refractive index, and it is possible that the Sr 3 P 4 O 13 is used to make transparent material between the UV and FR light zone

    To investigate the association between the occurrence of uterine leiomyoma and two SNPs of the CYP 2A13 and CYP 1A1 genes. Prospective case control study with 132 women with clinically and surgically diagnosed uterine leiomyoma and 260 controls. Genotyping was performed by polymerase chain reaction (PCR) based amplification of CYP 2A13 and CYP 1A1 genes, and restriction fragment length polymorphism (RFLP) analysis. Comparing women with uterine leiomyoma and controls, we demonstrate statistical significant differences of allele frequency and genotype distribution for the CYP 1A1 polymorphism (P = 0.025 and P = 0.046, respectively). Furthermore, for the CYP 2A13 polymorphism we found a significant difference concerning allele frequency (P = 0.033). However, for the genotype distribution, only borderline significance was observed (P = 0.064). The CYP 2A13 and CYP 1A1 SNPs are associated with uterine leiomyoma in a Caucasian population and may contribute to the understanding of the pathogenic mechanisms of uterine leiomyoma.

    The MesoDyn method is used to investigate associative structures in aqueous solution of a nonionic triblock copolymer consisting of poly(propylene oxide) capped on both ends with poly(ethylene oxide) chains. The effect of adsorbing (hydrophobic) and nonadsorbing (hydrophilic) solid surfaces in contact with aqueous solutions of the polymer is elucidated. The macromolecules form self-assembled structures in solution. Confinement under shear forces is investigated in terms of interfacial behavior and association. The formation of micelles under confinement between hydrophilic surfaces occurs faster than in bulk aqueous solution while layered structures assemble when the polymers are confined between hydrophobic surfaces. Micelles are deformed under shear rates of 1 μs -1 and eventually break to form persistent, adsorbed layered structures. As a result, surface damage under frictional forces is prevented. Overall, this study indicates that aqueous triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (Pluronics, EO mPO nEO m) act as a boundary lubricant for hydrophobic surfaces but not for hydrophilic ones. © 2011 American Chemical Society.

    Earlier this year, Robert Kitchen (Eos, 87(24), 235, 2006) drew attention to declining interest in Earth science education in public schools. The reason for a lack of interest in teaching Earth sciences in public schools may involve more than just the attitudes of parents who may wish for their children a better preparation for advanced placement courses later on. Part of the problem may lie with our present mind-set that technology can solve all the world's problems, from poverty, to better health, and to prosperity.

    Full Text Available O presente estudo teve o objetivo de analisar a interação educadora-criança em creches públicas, considerando os estilos linguísticos das educadoras e a comunicação infantil. O estudo dos estilos linguísticos destaca-se nas análises das interações entre adultos e crianças, especialmente em se tratando daquelas da faixa etária em torno dos 24 meses, devido à emergência das primeiras pequenas frases. Participaram do estudo seis educadoras e doze crianças com idade entre 23 e 25 meses, que frequentavam creches públicas de João Pessoa, Paraíba. As interações entre educadora e criança foram observadas sistematicamente em contextos diádicos e poliádicos de leitura. Categorias interacionais foram elaboradas a posteriori, para a análise dos dados. As educadoras utilizaram mais estilos associados à promoção do desenvolvimento linguístico nos contextos diádicos, enquanto os estilos relacionados à direção e ao controle dos comportamentos predominaram nos contextos poliádicos. As análises consideraram a influência mútua entre os estilos comunicativos e o nível de desenvolvimento linguístico infantil, além dos aspectos contextuais.

    Full Text Available Diferentes sistemas de uso e manejo alteram o teor de carbono no solo (C, porém diminuições no C do solo têm sido reportadas quando áreas de Cerrado nativo são convertidas em pastagem. Disso resulta a necessidade da realização de pesquisas em diferentes sistemas e condições edafoclimáticas, a fim de elucidar as tendências encontradas. O objetivo deste trabalho foi avaliar a agregação, os teores de C e a abundância natural de δ13C do solo em uma área cultivada há nove anos sob lavoura seguida de 20 anos sob pastagem, a qual atualmente apresenta sinais de degradação (PA, comparando-a a uma vegetação nativa no bioma Cerrado (CE que ocorre em área adjacente. As áreas de estudo estão localizadas no município de Rio Verde (GO, em solo classificado como Latossolo Vermelho distrófico, de textura argilosa. Em amostras de solo coletadas nas camadas de 0-5, 5-10 e 10-20 cm de profundidade, foram determinados a distribuição de agregados estáveis em água (micro, meso e macroagregados, o diâmetro médio aritmético (DMA e geométrico (DMG, os teores de C total e de δ13C, o tempo de residência média do C (TRM e a fração da matéria orgânica leve livre (FLL. Os resultados indicaram que o uso sob lavoura seguido de pastagem reduziu em 21 % o estoque de C original, possivelmente devido ao menor aporte de material na FLL. O solo apresentou elevada agregação e não houve diferenças significativas entre as áreas avaliadas. No entanto, os teores de C nos macroagregados foram menores na PA em relação ao CE, enquanto nos microagregados não houve diferença entre os sistemas de uso, sugerindo, respectivamente, maior e menor sensibilidade ao manejo e menor e maior proteção do C por essas classes de agregados. Os valores de TRM e as análises isotópicas reforçaram esses resultados, mostrando, ainda, substituição de 83 % do C original durante os 29 anos de cultivo.

    Full Text Available Triphenylmethane dyes represent a major group of dyes causing serious environmental hazards. Malachite Green is one of the commonly and extensively used triphenylmethane dyes although it is carcinogenic and mutagenic in nature. Various physicochemical methods have been employed for its elimination but are highly expensive, coupled with the formation of huge amount of sludge. Hence, biological methods being ecofriendly are good alternatives. In the present study, the novel bacterial isolate SA13P was isolated from UASB tank of tannery effluent treatment plant. Phylogenetic characterization of 1470 bp fragment of SA13P has revealed its similarity with Castellaniella denitrificans. This strain has been found to decolorize the dye (malachite green at a concentration of 100 mg L−1 (80.29%. Decolorization was done by living bacterial cells rather than adsorption. Growth conditions have also been optimized for the decolorization. Maximum decolorization was observed at a temperature of 37°C and pH 8.0. Also, it has been found that bacterization of seeds of Vigna radiata with Castellaniella denitrificans SA13P increases germination rate. We have reported for the first time that Castellaniella denitrificans SA13P may be used as a novel strain for dye decolorization (malachite green and biological treatment of tannery effluent.

    NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) is a virtual system that provides near real-time EOS data and imagery to meet the needs of scientists and application users interested in monitoring a wide variety of natural and man-made phenomena in near real-time. Over the last year: near real-time products and imagery from MOPITT, MISR, OMPS and VIIRS (Land and Atmosphere) have been added; the Fire Information for Resource Management System (FIRMS) has been updated and LANCE has begun the process of integrating the Global NRT flood product. In addition, following the AMSU-A2 instrument anomaly in September 2016, AIRS-only products have replaced the NRT level 2 AIRS+AMSU products. This presentation provides a brief overview of LANCE, describes the new products that are recently available and contains a preview of what to expect in LANCE over the coming year.

    The Earth Observing System (EOS), part of a cohesive national effort to study global change, will deploy a constellation of remote sensing spacecraft over a 15 year period. Science data from the EOS spacecraft will be processed and made available to a large community of earth scientists via NASA institutional facilities. A number of these spacecraft are also providing an additional interface to broadcast data directly to users. Direct broadcast of real-time science data from overhead spacecraft has valuable applications including validation of field measurements, planning science campaigns, and science and engineering education. The success and usefulness of EOS direct broadcast depends largely on the end-user cost of receiving the data. To extend this capability to the largest possible user base, the cost of receiving ground stations must be as low as possible. To achieve this goal, NASA Goddard Space Flight Center is developing a prototype low-cost transportable ground station for EOS direct broadcast data based on Very Large Scale Integration (VLSI) components and pipelined, multiprocessing architectures. The targeted reproduction cost of this system is less than $200K. This paper describes a prototype ground station and its constituent components.

    Full Text Available O planejamento é uma importante função administrativa e sua execução possibilita o alcance dos objetivos estabelecidos na organização. Na enfermagem, planejar e executar atividades são imprescindíveis para garantir assistência com qualidade. A presente pesquisa trata-se de estudo descritivo, com abordagem qualitativa, realizado em um hospital de grande porte que teve como objetivo geral analisar as percepções dos gerentes quanto ao planejamento e execução de atividades de enfermagem em hospital da rede pública de assistência e ensino de Goiânia - Goiás. Participaram como sujeitos, 17 (dezessete gerentes de enfermagem das unidades ambulatoriais e de internação. Os dados foram coletados por meio de entrevistas semi-estruturadas e analisados conforme o que preconiza Bardin (1979. Os resultados mostraram que os gerentes elaboram o planejamento melhor do que o conceituam e que existem fatores que interferem no planejamento e execução das atividades. Concluiu-se que os gerentes adotam o planejamento participativo, indicando mudança de paradigma na administração. Entre os fatores facilitadores, estão a adoção do trabalho em equipe, a proximidade entre gerência e servidores, incentivo à criatividade e interesse na execução das ações planejadas. Os fatores dificultadores incluem a escassez de recursos humanos, materiais e financeiros; fatores relacionados aos componentes da equipe, tais como: motivação, falta de tempo, ausência de treinamento, dificuldades em gerenciar; insuficiência de apoio da instituição e de outros serviços do hospital; estrutura física inadequada; e as intercorrências do cotidiano. A origem destes fatores foi atribuída às próprias pessoas, ao fato do hospital pertencer à rede pública, à instituição e ao sistema utilizado para o gerenciamento dos serviços de apoio.

    Distal limb contractures (DLC) represent a heterogeneous clinical and genetic condition. Overall, 20-25% of the DLC are caused by mutations in genes encoding the muscle contractile apparatus. Large interstitial deletions of the 3p have already been diagnosed by standard chromosomal analysis, but not associated with a specific phenotype. We report on four patients with syndromic DLC presenting with a de novo 3p14.1p13 microdeletion. The clinical features associated multiple contractures, feeding problems, developmental delay, and intellectual disability. Facial dysmorphism was constant with low-set posteriorly rotated ears and blepharophimosis. Review of previously reported cases with a precise mapping of the deletions, documented a 250 kb smallest region of overlap (SRO) necessary for DLC. This region contained one gene, EIF4E3, the first three exons of the FOXP1 gene, and an intronic enhancer of FOXP1 named hs1149. Sanger sequencing and locus quantification of hs1149, EIF4E3, and FOXP1 in a cohort of 11 French patients affected by DLC appeared normal. In conclusion, we delineate a new microdeletion syndrome involving the 3p14.1p13 locus and associated with DLC and severe developmental delay. © 2014 Wiley Periodicals, Inc.

    2018-05-01

    21-cm observations of the Cosmic dawn (CD) and Epoch of Reionization (EoR) are one of the high priority science objectives for SKA Low. One of the most difficult aspects of the 21-cm measurement is the presence of foreground emission, due to our Galaxy and extragalactic sources, which is about four orders of magnitude brighter than the cosmological signal. While end-to-end simulations are being produced to investigate in details the foreground subtraction strategy, it is useful to complement this thorough but time-consuming approach with simpler, quicker ways to evaluate performance and identify possible critical steps. In this work, I present a forecast method, based on Bonaldi et al. (2015), Bonaldi & Ricciardi (2011), to understand the level of residual contamination after a component separation step, and its impact on our ability to investigate CD and EoR.

    The tree canopy characterization presented herein provided ground and tree canopy data for different types of tree canopies in support of EO-1 reflective and thermal infrared validation studies. These characterization efforts during August and September of 2001 included stem and trunk location surveys, tree structure geometry measurements, meteorology, and leaf area index (LAI) measurements. Measurements were also collected on thermal and reflective spectral properties of leaves, tree bark, leaf litter, soil, and grass. The data presented in this report were used to generate synthetic reflective and thermal infrared scenes and images that were used for the EO-1 Validation Program. The data also were used to evaluate whether the EO-1 ALI reflective channels can be combined with the Landsat-7 ETM+ thermal infrared channel to estimate canopy temperature, and also test the effects of separating the thermal and reflective measurements in time resulting from satellite formation flying.

    Full Text Available No presente trabalho, estudaram-se características associadas à germinação in vitro e ao desenvolvimento in vivo do tubo polínico em seis variedades-copa e de porta-enxertos de macieira como subsídios para o estabelecimento de programas de melhoramento genético. Utilizou-se de pólen de seis cultivares de macieira inoculado em meio de cultura com ágar (10 g.L-1 em água destilada, combinados com concentrações de sacarose (0; 10; 20; 30; 40 e 50% e ácido bórico (0 e 40 mg.L-1. Para o estudo do desenvolvimento do tubo polínico, realizou-se coleta das flores em quatro períodos (6; 12; 24 e 48 horas após as polinizações em M9 x Marubakaido e a autofecundação em M9, sendo os tubos polínicos analisados em coloração de azul de anilina acidificada/carmim acético e em fluorescência. A sacarose, em concentrações entre 15% a 25%, pode ser empregada com sucesso para a germinação in vitro de grãos de pólen da macieira. O ácido bórico não teve efeito positivo para esta característica. Na ausência do ácido bórico e na presença de 15% de sacarose, observaram-se os maiores percentuais de germinação: Fuji (51,1%, Imperatriz (31,7%, M.9 (20,8%, Catarina (19,2%, Gala (13,7% e Marubakaido (6,1%. Quanto ao desenvolvimento do tubo polínico, com 12 horas da polinização, iniciou-se a germinação no pólen, no estigma, no cruzamento M.9 x Marubakaido, e após 24 horas da polinização observou-se 83% de germinação. As técnicas de coloração com azul de anilina acidificada com carmim acético e de visualização em fluorescência foram eficientes na visualização e coloração dos grãos de pólen e do desenvolvimento dos tubos polínicos.In the present work it was studied features associated to the germination of pollen and the development of pollen tubes in six apple varieties as subsidies for the establishment of genetic improvement programs. Pollen grains were inoculated in culture medium with distilled water, agar (10

    Full Text Available RESUMO O objetivo do trabalho foi elaborar um meio de cultura para avaliação da viabilidade polínica e determinar o número de grãos de pólen por antera e por flor de espécies de fisális. O trabalho foi desenvolvido de forma sequencial, onde grãos de pólen de Physalis (P. angulata,P. ixocarpa,P. minima,P. peruviana e P. pubescens foram submetidos à germinação em meio de cultura desenvolvido em quatro fases: verificação da concentração de ágar e pH, concentração de sacarose, nitrato de cálcio e ácido bórico. Para a contagem de grãos de pólen, cinco anteras foram coletadas entre cinco espécimes representativos de cada espécie, deixadas em repouso para ocorrência da deiscência e posteriormente adicionado ácido lático, para melhoria da visualização do grão de pólen. Após 48 horas o número de grãos de pólen foi quantificado com auxílio de câmara de Neubauer e o número de grãos de pólen por antera determinado por fórmula pré-estabelecida. Observou-se que todas as espécies possuem comportamento semelhante quanto às suas exigências para germinação do grão de pólen, sendo o pH do meio em torno de 5,4 e a concentração de ágar de 8 g L-1; todas as espécies mostram dependência de cálcio e boro para uma melhor viabilidade polínica, destacando-se P. minima em que a adição de boro não propiciou elevação acentuada na porcentagem de germinação. Quanto ao número de grãos de pólen as espécies podem ser divididas em dois grupos, com P. angulata,P. peruviana e P. pubescens com maior número de grãos de pólen por antera e por flor em relação a P. ixocarpa e P. minima.

    2005-11-01

    Full Text Available Esculturas e monumentos públicos tradicionalmente foram construídos e pensados segundo a lógica do poder vigente, para difusão e fixação de seus pontos de vista. A partir do período entre guerras, o cenário político brasileiro discute as propostas iconográficas dos partidos nazifascistas e comunistas europeus, até o fim do regime Vargas, em uma política de afirmação de símbolos concretos de nacionalidade e poder. O escopo deste artigo é discutir essas heranças autoritárias por meio do estudo de monumentos encontrados em praças públicas de Curitiba, assim como entender como as idéias e o ambiente político da época informaram suas soluções visuais. O estudo da recepção das imagens ajuda-nos a entender as relações entre a população e o status quo, e as suas lutas internas, muitas vezes encobertas por debates aparentemente "apenas" estéticos.

    Full Text Available Foi avaliada a manutenção da qualidade pós-colheita dos frutos em cultivares brasileiras de goiabeira-serrana. Frutos das cultivares Alcântara, Helena, Mattos e Nonante foram colhidos na maturação comercial, no município de São Joaquim-SC, e armazenados a 4±1 ºC (90±5% UR, durante 21 dias, seguido de 8 e 48 h a 23±1 ºC (75±5% UR. Foram avaliadas a composição mineral (N, K, Mg e Ca na colheita e a qualidade dos frutos na colheita e após o armazenamento. Frutos da cultivar Nonante apresentaram na colheita maiores valores de acidez titulável (AT pH e de atributos de textura, e menores valores de pH e da relação sólidos solúveis/acidez titulável (SS/AT, sendo que, após o armazenamento refrigerado, este comportamento foi reduzido, com menores diferenças em relação às demais cultivares. Frutos de 'Nonante' apresentaram também maiores teores de K na casca e polpa, e menores teores de N na polpa e, após o armazenamento refrigerado, cor verde menos intensa na casca e menor escurecimento de polpa. Em relação aos dados de colheita, após o armazenamento refrigerado, houve maior redução na AT (41% do que no teor de SS (8,6%, o que ocasionou acentuado aumento na relação SS/AT (52,5%, considerando valores médios das quatro cultivares. Isto evidencia que, em goiaba-serrana, os ácidos orgânicos representam o principal substrato respiratório durante o armazenamento, o que compromete a qualidade sensorial pelo aumento na relação SS/AT. Frutos de 'Alcântara' foram também avaliados quanto aos efeitos do dano mecânico na colheita e do retardo no armazenamento refrigerado, na qualidade após o armazenamento. O dano mecânico na colheita (dano por queda, a uma altura de 50 cm, sobre uma superfície rígida ocasionou mínimo comprometimento da qualidade após o armazenamento refrigerado. Frutos desta cultivar apresentaram redução na AT (31%, textura da periderme (33% e força para a compressão (13%, e aumento no pH (20% e

    Full Text Available O conhecimento das mudanças que ocorrem no útero e ovários durante a puberdade é fundamental ao investigar alterações da pelve feminina em crianças e adolescentes. O exame ultrassonográfico nestas pacientes é rotineiramente realizado por via abdominal usando o líquido da bexiga como uma janela ultrassônica, embora possa ser algumas vezes realizado pela via vaginal em adolescentes sexualmente ativas. As principais indicações para ultrassonografia pélvica em crianças e adolescentes são a puberdade precoce ou atrasada, dor ou massas pélvicas, genitália ambígua, sangramento vaginal em crianças e amenorreia primária. Neste artigo relatamos a técnica do exame, além de descrever os achados mais freqüentes.The knowledge of uterine and ovarian changes in the puberty is essential in the investigation changes in the female pelvis of children and teenagers. In these patients, pelvic ultrasonography is routinely performed with a full bladder to produce an acoustic window, although this examination may also be performed with endovaginal approach in sexually active teenagers. Main indications for pelvic ultrasonography in children and teenagers are either early or delayed puberty, pelvic pain or tumors, ambiguous genitalia, vaginal bleeding in children, and primary amenorrhea. In the present paper, the authors describe the scanning technique and the most frequent sonographic findings.

    Full Text Available Este artigo teve como objetivo examinar o efeito dos investimentos públicos em saúde na mortalidade dos idosos no Rio Grande do Sul, controlando-se pelas características socioeconômicas dos municípios. A base de dados foi extraída do Censo Demográfico do IBGE de 2000 e do Datasus, o qual inclui informações sobre recursos regionais para a saúde em 7 meso-regiões do RS. Foi criada uma tipologia para classificar as regiões do RS com base na taxa de dependência idosa. Modelos de regressões lineares estimaram o efeito dos investimentos públicos na mortalidade dos idosos separadamente por grupos de taxa de dependência controlando-se pelo PIB per capita, o índice de Gini, renda per capita, média de anos de estudo e a taxa de urbanização (variáveis independentes. Apesar de ter a expectativa de vida mais alta do Brasil, os resultados desse estudo revelam significativa diferença na mortalidade dos idosos entre as 7 meso-regiões que compõem o Estado do Rio Grande do Sul. os resultados mostram que os investimentos públicos federais em saúde são maiores em regiões com baixa taxa de dependência idosa. Também observamos uma associação frágil entre os investimentos públicos em saúde e a mortalidade dos idosos.

    Full Text Available Enteral diets constitute an excellent means for microbial growth due to its composition rich in nutrients and its time of exposure to room temperature during application. Among the pathogenic bacteria there is the Staphylococcus aureus that is an opportunist microorganism found in the humans’ mucous membrane (buccal, nasal and oral. Samples of enteral diet after application as well as of the environment used for the preparation of the diets, were collected in a public hospital in Minas Gerais and analyzed for the presence of S. aureus. The contamination by S. aureus was evidenced in 83% of the enteral diet samples. As for the environment, the values found were in conformity with APHA recommendation. The isolated strains were submitted to the evaluation of the resistance to different antibiotics. Resistance was observed for tetracycline (100%, erythromycin (90,9%, chloramphenicol (59,1%, estreptomycin (22,72%, penicillin 18,8%, vancomycin (13,63%, ampicillin (13,63%, amoxilin (9,09% and gentamicin (4,54%. Due to the versatility in the resistance development to several antibiotics the S. aureus survives in hospital environments and can be diffused among patients. Dietas enterais constituem um excelente meio para crescimento microbiano, devido à sua composição rica em nutrientes e ao tempo de exposição à temperatura ambiente durante a administração. Dentre as bactérias patogênicas que podem ser encontradas nessas dietas, cita-se o Staphylococcus aureus, microrganismo oportunista encontrado na microbiota da membrana mucosa (bucal, nasal e oral em seres humanos. Amostras de dieta enteral pós-administração e do ambiente utilizado para o seu preparo foram coletadas em um hospital público e analisadas quanto à presença de S. aureus.

    Full Text Available The elliptic-flow ratio of neutrons with respect to protons or light complex particles in reactions of heavy ions at pre-relativistic energies has been proposed as an observable sensitive to the strength of the symmetry term of the nuclear equation of state at supra-saturation densities. In the ASY-EOS experiment at the GSI laboratory, flows of neutrons and light charged particles were measured for 197Au+197Au collisions at 400 MeV/nucleon. Flow results obtained for the Au+Au system, in comparison with predictions of the UrQMD transport model, confirm the moderately soft to linear density dependence of the symmetry energy deduced from the earlier FOPI-LAND data.

    Full Text Available FUNDAMENTO: No período pós-menopausa, a presença dos fatores de risco para doença arterial coronária (DAC aumentam. Entretanto, não é bem estabelecida a diferença de prevalência de isquemia miocárdica em mulheres pré/pós-menopausa com múltiplos fatores de risco para DAC. OBJETIVO: Comparar a prevalência de isquemia na cintilografia de perfusão miocárdica com sestamibi-99mTc (CPM em mulheres nos períodos pré/pós-menopausa e avaliar se a menopausa pode ser considerada fator preditor de risco independente para isquemia em mulheres com múltiplos fatores de risco para DAC. MÉTODOS: Analisamos, retrospectivamente, 500 CPM de mulheres pré/pós-menopausa, com múltiplos fatores de risco cardiovascular. A análise estatística foi realizada por teste exato de Fisher e pelas análises univariada e multivariada, sendo considerado significativo o valor de p < 0,05. RESULTADOS: Do total, 55,9% das mulheres estavam no período pós-menopausa, 83,3% eram hipertensas, 28,9% diabéticas, 61,2% dislipidêmicas, 32,1% tabagistas, 25% obesas e 34,3% já apresentavam DAC conhecida. No grupo pós-menopausa, as mulheres eram mais hipertensas, diabéticas e dislipidêmicas, e tiveram menor capacidade funcional no teste ergométrico (p = < 0,005. Não houve diferença estatística significativa na presença de isquemia na CPM entre os grupos pré/pósmenopausa (p = 0,395. A única variável associada à isquemia na CPM foi a presença de DAC prévia (p = 0,004. CONCLUSÃO: Os resultados obtidos sugerem que, em mulheres com múltiplos fatores de risco para DAC, a menopausa não foi fator preditor independente de isquemia na CPM. Essas informações reforçam a ideia de que a investigação de isquemia pela CPM em mulheres com múltiplos fatores de risco para DAC talvez deva iniciar antes da menopausa.

    Full Text Available <p>Despite almost a hundred years of separation, both Cecil B. DeMille’s film <em>The Cheatem> (1915 and John Updike’s novel <em>Terrorist> (2006 deploy a clear-cut territorial divide between Western and Eastern spaces in order to envision a unified American space. These narratives superimpose a “natural” division on these historically opposed spaces and thereby suggest that any contact between these spaces will have dangerous consequences. These consequences include the potential dissolution and eventual destruction of American productivity, surveillance, and territorial integrity. DeMille’s film and Updike’s novel represent America as a nation-state that must be protected from the East. In 1915, <em>The Cheatem> warned against an interracial America and the upsurge in immigration that characterized the turn of the century. Nearly a century later, <em>Terrorist> presupposes an interracial America but still constructs an East that threatens the security of America. While registering the particular concerns of two distinct historical moments, these narratives represent a larger attempt in American aesthetics to imagine an East that jeopardizes the utopian possibilities of an overly idealized American space.p>

    Directory of Open Access Journals (Sweden)

    Edimar Inocencio Brígido

    2017-10-01

    Full Text Available O artigo pretende revisitar a definição de uso público da razão e a impossibilidade da sua renúncia segundo Hannah Arendt com base em elementos que ela identificou na obra: “Eichmann em Jerusalém, um relato sobre a banalidade do mal”. Para tanto, apresenta uma breve evolução do conceito ético-político de razão e seu uso de Sócrates até o Iluminismo e aponta a ligação do pensamento de Arendt ao de Kant, para identificar a ampliação que ela faz da análise do uso da faculdade de julgar desenvolvida por ele. Isso porque a visão oitocentista da faculdade de julgar se mostrou insuficiente para explicar os efeitos históricos que a renúncia ao uso público da razão acarreta para a civilização a partir do fim do século XIX até os dias de hoje. Isso por força da escalada dos genocídios e massacres do período. Para isso, colheu-se dados históricos, literários e de reflexões de autores, cujo pensamento é próximo ao de Arendt e recorreu-se a outras obras da autora, tudo para ilustrar e explicar que a escalada genocida e dos massacres se dá em consonância com o crescimento das sociedades de massa industrial e pós-industrial. A conclusão a que se chega é de que a renúncia à faculdade de julgar derivada do modelo econômico e social atual e leva a uma aporia: uma contraditória ameaça à vida em nome da vida.

    Deletions at 16p13.11 are associated with schizophrenia, mental retardation, and most recently idiopathic generalized epilepsy. To evaluate the role of 16p13.11 deletions, as well as other structural variation, in epilepsy disorders, we used genome-wide screens to identify copy number variation in 3812 patients with a diverse spectrum of epilepsy syndromes and in 1299 neurologically-normal controls. Large deletions (> 100 kb) at 16p13.11 were observed in 23 patients, whereas no control had a deletion greater than 16 kb. Patients, even those with identically sized 16p13.11 deletions, presented with highly variable epilepsy phenotypes. For a subset of patients with a 16p13.11 deletion, we show a consistent reduction of expression for included genes, suggesting that haploinsufficiency might contribute to pathogenicity. We also investigated another possible mechanism of pathogenicity by using hybridization-based capture and next-generation sequencing of the homologous chromosome for ten 16p13.11-deletion patients to look for unmasked recessive mutations. Follow-up genotyping of suggestive polymorphisms failed to identify any convincing recessive-acting mutations in the homologous interval corresponding to the deletion. The observation that two of the 16p13.11 deletions were larger than 2 Mb in size led us to screen for other large deletions. We found 12 additional genomic regions harboring deletions > 2 Mb in epilepsy patients, and none in controls. Additional evaluation is needed to characterize the role of these exceedingly large, non-locus-specific deletions in epilepsy. Collectively, these data implicate 16p13.11 and possibly other large deletions as risk factors for a wide range of epilepsy disorders, and they appear to point toward haploinsufficiency as a contributor to the pathogenicity of deletions.

    Full Text Available Cet article a pour ambition d’interroger le rapport du public à une salle de cinéma précise, au cœur du parc Disneyland Paris à Marne-La-Vallée. Cette salle projette à nouveau depuis juin 2010 l’attraction Captain Eo, film de science-fiction en 3D relief réalisé par Francis Ford Coppola en 1986, avec Michael Jackson dans le rôle-titre. Remplacé depuis 1998 par une autre attraction, Captain Eo fait son retour un an après le décès de la star, et implique dès lors un rapport très particulier à son public, par son statut d’hommage post-mortem. Il s’agira de comprendre la façon dont l’attraction structure son public, et la façon dont celui-ci peut construire à son tour le sens du film qu’il est en train de voir. C’est donc une approche sémio-pragmatique que nous convoquons ici, en nous référant à Roger Odin, afin d’envisager, à partir du film lui-même et de son mode de diffusion, ce que l’attraction Captain Eo révèle théoriquement du lien entre le spectateur et l’image d’une star comme Michael Jackson, qui plus est un an après son décès. Il s’agira de comprendre de quelle manière le film de Coppola ainsi que son contexte de diffusion – le parc d’attraction Disneyland Paris – permettent de penser ou d’interroger un type de pratique spectatorielle différent de celles engendrées par d'autres salles de cinéma.This article tries to question the link between the public and a precise movie theater, in Disneyland Paris Marne-La-Vallée, proposing again since june 2010 the attraction Captain Eo, science-fiction 3D movie by Francis Ford Coppola in 1986, starring Michael Jackson.

    Objectives: To evaluate the cost-effectiveness of the EOS ® 2D/3D X-ray imaging system compared with standard X-ray for the diagnosis and monitoring of orthopaedic conditions. Materials and methods: A decision analytic model was developed to quantify the long-term costs and health outcomes, expressed as quality-adjusted life years (QALYs) from the UK health service perspective. Input parameters were obtained from medical literature, previously developed cancer models and expert advice. Threshold analysis was used to quantify the additional health benefits required, over and above those associated with radiation-induced cancers, for EOS ® to be considered cost-effective. Results: Standard X-ray is associated with a maximum health loss of 0.001 QALYs, approximately 0.4 of a day in full health, while the loss with EOS ® is a maximum of 0.00015 QALYs, or 0.05 of a day in full health. On a per patient basis, EOS ® is more expensive than standard X-ray by between £10.66 and £224.74 depending on the assumptions employed. The results suggest that EOS ® is not cost-effective for any indication. Health benefits over and above those obtained from lower radiation would need to double for EOS to be considered cost-effective. Conclusion: No evidence currently exists on whether there are health benefits associated with imaging improvements from the use of EOS ® . The health benefits from radiation dose reductions are very small. Unless EOS ® can generate additional health benefits as a consequence of the nature and quality of the image, comparative patient throughput with X-ray will be the major determinant of cost-effectiveness

  19. Male-biased autosomal effect of 16p13.11 copy number variation in neurodevelopmental disorders.

    Maria Tropeano

    Full Text Available Copy number variants (CNVs at chromosome 16p13.11 have been associated with a range of neurodevelopmental disorders including autism, ADHD, intellectual disability and schizophrenia. Significant sex differences in prevalence, course and severity have been described for a number of these conditions but the biological and environmental factors underlying such sex-specific features remain unclear. We tested the burden and the possible sex-biased effect of CNVs at 16p13.11 in a sample of 10,397 individuals with a range of neurodevelopmental conditions, clinically referred for array comparative genomic hybridisation (aCGH; cases were compared with 11,277 controls. In order to identify candidate phenotype-associated genes, we performed an interval-based analysis and investigated the presence of ohnologs at 16p13.11; finally, we searched the DECIPHER database for previously identified 16p13.11 copy number variants. In the clinical referral series, we identified 46 cases with CNVs of variable size at 16p13.11, including 28 duplications and 18 deletions. Patients were referred for various phenotypes, including developmental delay, autism, speech delay, learning difficulties, behavioural problems, epilepsy, microcephaly and physical dysmorphisms. CNVs at 16p13.11 were also present in 17 controls. Association analysis revealed an excess of CNVs in cases compared with controls (OR = 2.59; p = 0.0005, and a sex-biased effect, with a significant enrichment of CNVs only in the male subgroup of cases (OR = 5.62; p = 0.0002, but not in females (OR = 1.19, p = 0.673. The same pattern of results was also observed in the DECIPHER sample. Interval-based analysis showed a significant enrichment of case CNVs containing interval II (OR = 2.59; p = 0.0005, located in the 0.83 Mb genomic region between 15.49-16.32 Mb, and encompassing the four ohnologs NDE1, MYH11, ABCC1 and ABCC6. Our data confirm that duplications and deletions at 16p13

    Full Text Available To retrospectively assess the interreader reproducibility and reliability of EOS 3D full spine reconstructions in patients with adolescent idiopathic scoliosis (AIS.73 patients with mean age of 17 years and a moderate AIS (median Cobb Angle 18.2° obtained low-dose standing biplanar radiographs with EOS. Two independent readers performed "full spine" 3D reconstructions of the spine with the "full-spine" method adjusting the bone contour of every thoracic and lumbar vertebra (Th1-L5. Interreader reproducibility was assessed regarding rotation of every single vertebra in the coronal (i.e. frontal, sagittal (i.e. lateral, and axial plane, T1/T12 kyphosis, T4/T12 kyphosis, L1/L5 lordosis, L1/S1 lordosis and pelvic parameters. Radiation exposure, scan-time and 3D reconstruction time were recorded.Interclass correlation (ICC ranged between 0.83 and 0.98 for frontal vertebral rotation, between 0.94 and 0.99 for lateral vertebral rotation and between 0.51 and 0.88 for axial vertebral rotation. ICC was 0.92 for T1/T12 kyphosis, 0.95 for T4/T12 kyphosis, 0.90 for L1/L5 lordosis, 0.85 for L1/S1 lordosis, 0.97 for pelvic incidence, 0.96 for sacral slope, 0.98 for sagittal pelvic tilt and 0.94 for lateral pelvic tilt. The mean time for reconstruction was 14.9 minutes (reader 1: 14.6 minutes, reader 2: 15.2 minutes, p<0.0001. The mean total absorbed dose was 593.4μGy ±212.3 per patient.EOS "full spine" 3D angle measurement of vertebral rotation proved to be reliable and was performed in an acceptable reconstruction time. Interreader reproducibility of axial rotation was limited to some degree in the upper and middle thoracic spine due the obtuse angulation of the pedicles and the processi spinosi in the frontal view somewhat complicating their delineation.

    at doses recommended for bean crop, these herbicides may be applied to control weeds in coffee and bean intercropping systems by spraying the entire area.Este trabalho foi realizado com o objetivo de investigar, em campo, a eficiência de vários herbicidas aplicados em pós-emergência em área total no controle de plantas daninhas, em cafezais recém-implantados e no consórcio de café e feijão, assim como seus efeitos sobre essas culturas. Mudas de Coffea arabica, cultivar Catuaí Vermelho, com quatro a seis pares de folhas foram transplantadas para o campo e cultivadas segundo práticas agronômicas usuais. O consórcio de café e feijão foi obtido por meio do plantio de três linhas de feijão nas entrelinhas do cafezal. Quando os herbicidas foram aplicados sobre as culturas, as plantas de café estavam com seis a dez pares de folhas, as de feijão com três folíolos e as plantas daninhas no estádio inicial de desenvolvimento. Fluazifop-p-butil e clethodim foram seletivos às plantas de café e controlaram eficientemente Brachiaria plantaginea e Digitaria horizontalis. Plantas daninhas dicotiledôneas (Amaranthus retroflexus, Bidens pilosa, Coronopus didymus, Emilia sonchifolia, Galinsoga parviflora, Ipomoea grandifolia, Lepidium virginicum e Raphanus raphanistrum foram controladas eficientemente por aplicações isoladas de fomesafen, flazasulfuron e oxyfluorfen, com exceção de B. pilosa, C. didymus e R. raphanistrum para o oxyfluorfen. Aplicações seqüenciais com intervalos de sete dias de fomesafen + fluazifop-p-butil ou clethodim, e as duas misturas comerciais de fomesafen + fluazifop-p-butil controlaram simultaneamente ambos os tipos de plantas daninhas. Cyperus rotundus foi controlada apenas por flazasulfuron. Com exceção de fluazifop-p-butil e clethodim todos os demais tratamentos herbicidas provocaram apenas leves injúrias às folhas mais novas das plantas de café. Contudo, o crescimento das plantas não foi prejudicado, de forma que tanto a

    Full Text Available Eosinophilic esophagitis (EoE is a chronic immune/antigen mediated inflammatory disease of the esophagus. It comprises a separate entity of increasing incidence and prevalence in children and adults. The disease is characterized by histological evidence of dense esophageal tissue eosinophilia in the presence of a variety of upper GI symptoms including vomiting, dysphagia, food impaction and odynophagia. Cornerstone of treatment is dietary intervention and/or the off-label use of swallowed topical corticosteroids. New drug therapies are under investigation. In this review we focus on the diagnostic approach and the currently available treatment strategies. Keywords: Eosinophilic esophagitis, oral viscous budesonide, fluticasone propionate, oral steroids, amino acid-based formula, empiric elimination diet, targeted elimination dietKey points:1.A trial with antisecretory medication is necessary to exclude GERD and PPI-responsive esophageal eosinophilia and to fulfil the diagnostic criteria of EoE. 2.Elimination diet and/or off-label use of topical corticosteroids are effective measures for treating EoE. 3.Elimination diet is the first line treatment in atopic children. 4.Systemic corticosteroids are reserved for patients with severe disease requiring immediate relief, or when other treatments have failed. 5.Cromolyn sodium (sodium cromoglycate and leukotriene receptor antagonists, are not currently recommended for treating EoE, due to lack of solid evidence of benefit.6.Immunosuppressive drugs and biologics have shown some value but effect has been limited and therefore not yet recommended as standard therapy.

    2018-06-01

    Full Text Available Ferulic acid (FA and p-hydroxybenzoic acid (PHBA are main phenolic compounds accumulated in rhizosphere of continuously cropped cucumber, causing stress in plants. Microbial degradation of a mixture of FA and PHBA is not well understood in soil. We isolated a strain CSY-P13 of Acinetobacter calcoaceticus, inoculated it into soil to protect cucumber from FA and PHBA stress, and explored a mechanism underlying the protection. CSY-P13 effectively degraded a mixture of FA and PHBA in culture solution under conditions of 39.37°C, pH 6.97, and 21.59 g L-1 potassium dihydrogen phosphate, giving rise to 4-vinyl guaiacol, vanillin, vanillic acid, and protocatechuic acid. During FA and PHBA degradation, activities of superoxide dismutase (SOD, catalase, ascorbate peroxidase, and dehydroascorbate reductase in CSY-P13 were induced. Inoculated into cucumber-planted soil containing 220 μg g-1 mixture of FA and PHBA, CSY-P13 degraded FA and PHBA in soil, increased plant height, and decreased malonaldehyde, superoxide radical, and hydrogen peroxide levels in leaves. CSY-P13 also enhanced SOD, guaiacol peroxidase, catalase, glutathione peroxidase, ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase activities; increased ascorbate and glutathione contents; and elevated transcript levels of copper/zinc SOD, manganese SOD, and catalase in leaves under FA and PHBA. Moreover, CSY-P13 increased phosphatase, catalase, urease, and sucrase activities and changed bacterial richness, diversity, and community composition by high throughput sequencing in cucumber-planted soil supplemented with the mixture of FA and PHBA. So CSY-P13 degrades the mixture of FA and PHBA in soil and mitigates stress from the two phenolic compounds in cucumber by activating antioxidant enzymes, changing soil bacterial community, and inducing soil enzymes.

    The epoch of reionization (EoR) 21-cm signal is expected to be highly non-Gaussian in nature and this non-Gaussianity is also expected to evolve with the progressing state of reionization. Therefore the signal will be correlated between different Fourier modes (k). The power spectrum will not be able capture this correlation in the signal. We use a higher order estimator - the bispectrum - to quantify this evolving non-Gaussianity. We study the bispectrum using an ensemble of simulated 21-cm signal and with a large variety of k triangles. We observe two competing sources driving the non-Gaussianity in the signal: fluctuations in the neutral fraction (x_{H I}) field and fluctuations in the matter density field. We find that the non-Gaussian contribution from these two sources varies, depending on the stage of reionization and on which k modes are being studied. We show that the sign of the bispectrum works as a unique marker to identify which among these two components is driving the non-Gaussianity. We propose that the sign change in the bispectrum, when plotted as a function of triangle configuration cos θ and at a certain stage of the EoR can be used as a confirmative test for the detection of the 21-cm signal. We also propose a new consolidated way to visualize the signal evolution (with evolving \\bar{x}_{H I} or redshift), through the trajectories of the signal in a power spectrum and equilateral bispectrum i.e. P(k) - B(k, k, k) space.

    Quality of care, job satisfaction and the health of registered nurses (RNs) are associated with their exposure to psychosocial and organisational work factors (POWFs). To develop and validate an extended version of the Revised Nursing Work Index (NWI-R), the NWI-EO (Extended Organisation) tool specifically designed for occupational physicians and those involved in prevention programmes in healthcare institutions to assess the perception of POWFs, and then to determine priorities for preventive action to improve work organisation at the hospital staff level. The tool was validated in the ORSOSA study, a multicentre French cohort of RNs and NAs (n=4085) recruited in 214 work units of 7 French university hospitals. A total of 34 items (19 candidate items developed by a focus group and 15 items from the NWI-R) were analysed using principal component analysis (PCA) based on a randomised split-half of the data. In addition, construct validity, test-retest reliability, internal consistency and concurrent validity were assessed. Response rate was 91%. Twenty-two items were selected (9 of the 15 NWI-R items and 13 of the 19 candidate items) by PCA, resulting in an 8-factor solution that explained 53% of the common variance. The stability of the factorial structure of this 22-item NWI-EO questionnaire was confirmed by PCA on the other half-sample as well as by PCA on subgroups (age, gender, occupational group, specialty area, hospital). Reliability, assessed by internal consistency and test-retest, was satisfactory. Concurrent validity with two external measurements of organisational characteristics of work units was also observed. The NWI-EO was found to have good psychometric properties. Several POWFs accessible to prevention programmes can be evaluated with this tool: poor communication in the work unit, lack of support from senior nurses, inadequate staffing to perform duties, poor relationships between workers, frequency of interruptions during tasks, low level of

    Full Text Available Neste artigo, apresentam-se os resultados de pesquisa qualitativa em que se objetivou investigar a aplicabilidade do método L.E.SCAnning em empresas sociais de economia peer-to-peer (P2P. A motivação partiu da ideia de a autossustentabilidade ser, a longo prazo, um dos maiores desafios das organizações, especialmente aquelas lastreadas na economia social, dentre elas, as empresas P2P. No entanto, empresas sociais são potencialmente negócios dinâmicos e progressistas com os quais o mercado empresarial poderia aprender, uma vez que experimentam e inovam. Partindo exatamente desse espírito inovador, muitas empresas sociais voltaram-se para o modelo crowdfunding de economia P2P, que se configura como tendência emergente de organização colaborativa de recursos na Web. Sob esse prisma, um dos novos desenvolvimentos em gestão que se aplicam à atividade de organizações com enfoque sistêmico é a prática da Inteligência Estratégica Antecipativa Coletiva (IEAc. Nesse sentido, no estudo de caso investigou-se a empresa social francesa Babyloan para compreender de que maneira a organização busca, monitora e utiliza a informação captada do meio externo para sua atuação, prototipando, com base nesse diagnóstico, a aplicação de um ciclo do método L.E.SCAnning. Os resultados deste estudo sugerem que o entendimento pragmático do cenário externo, por meio da IEAc, favorece decisões que trazem uma marca de empreendedorismo e inovação, e tem no universo da economia social P2P, ambiente fortemente baseado em percepção, um impacto potencial significativo.

    New pH-sensitive polyaspartamide derivatives were synthesized by grafting 1-(3-aminopropyl)imidazole and/or O-(2-aminoethyl)-O'-methylpoly(ethylene glycol) 5000 on polysuccinimide for application in intracellular drug delivery systems. The DS of 1-(3-aminopropyl)imidazole was adjusted by the feed molar ratio, and the structure of the prepared polymer was confirmed using FT-IR and 1H NMR spectroscopy. Their pH-sensitive properties were characterized by light transmittance measurements, and the particle size and its distribution were investigated by dynamic light scattering measurements at varying pH values. The pH-sensitive phase transition was clearly observed in polymer solutions with a high substitution of 1-(3-aminopropyl)imidazole. The prepared polymers showed a high buffering capacity between pH 5 and 7, and this increased with the DS of 1-(3-aminopropyl)imidazole. The pH dependence of the aggregation and de-aggregation behavior was examined using a fluorescence spectrometer. For MPEG/imidazole-g-polyaspartamides with a DS of 1-(3-aminopropyl)imidazole over 82%, self aggregates associated with the hydrophobic interactions of the unprotonated imidazole groups were observed at pH values above 7, and their mean size was over 200 nm, while the aggregates of polymers were dissociated at pH values below 7 by the protonation of imidazole groups. These pH-sensitive polyaspartamide derivatives are potential basic candidates for intracellular drug delivery carriers triggered by small pH changes.

    Full Text Available O intervalo pós-morte (IPM é um instrumento importante de diagnóstico relacionado à prática forense. O uso de insetos tem sido relatado como um modo eficiente para estimá-lo, quando o cadáver encontra-se em estágio avançado de decomposição. Objetivou-se com este trabalho estimar o IPM com base em evidências entomológicas em um canino. Foram coletadas larvas de moscas no cadáver e encaminhadas ao laboratório de entomologia, onde foram criadas e eclodiram adultos da espécie Chrysomya albiceps (Wiedemann, 1819. Somando-se os dados abióticos de temperatura e umidade relativa do local de coleta e do local de criação, estimou-se um IPM mínimo de 3,34 dias do momento da postura dos ovos pelas moscas até a coleta das larvas. Com base nos resultados obtidos, conclui-se que a entomologia forense, como ferramenta para estimativa do IPM, mostrou-se eficaz e determinante na elucidação do caso em questão.

    This paper addresses the efforts undertaken and the technology deployed to aggregate and distribute the metadata characterizing the real-time operations associated with NASA Earth Observing Systems (EOS) high-rate front-end systems and the science data collected at multiple ground stations and forwarded to the Goddard Space Flight Center for level 0 processing. Station operators, mission project management personnel, spacecraft flight operations personnel and data end-users for various EOS missions can retrieve the information at any time from any location having access to the internet. The users are distributed and the EOS systems are distributed but the centralized metadata accessed via an external web server provide an effective global and detailed view of the enterprise-wide events as they are happening. The data-driven architecture and the implementation of applied middleware technology, open source database, open source monitoring tools, and external web server converge nicely to fulfill the various needs of the enterprise. The timeliness and content of the information provided are key to making timely and correct decisions which reduce project risk and enhance overall customer satisfaction. The authors discuss security measures employed to limit access of data to authorized users only.

    Objectives: To evaluate the cost-effectiveness of the EOS{sup ®} 2D/3D X-ray imaging system compared with standard X-ray for the diagnosis and monitoring of orthopaedic conditions. Materials and methods: A decision analytic model was developed to quantify the long-term costs and health outcomes, expressed as quality-adjusted life years (QALYs) from the UK health service perspective. Input parameters were obtained from medical literature, previously developed cancer models and expert advice. Threshold analysis was used to quantify the additional health benefits required, over and above those associated with radiation-induced cancers, for EOS{sup ®} to be considered cost-effective. Results: Standard X-ray is associated with a maximum health loss of 0.001 QALYs, approximately 0.4 of a day in full health, while the loss with EOS{sup ®} is a maximum of 0.00015 QALYs, or 0.05 of a day in full health. On a per patient basis, EOS{sup ®} is more expensive than standard X-ray by between £10.66 and £224.74 depending on the assumptions employed. The results suggest that EOS{sup ®} is not cost-effective for any indication. Health benefits over and above those obtained from lower radiation would need to double for EOS to be considered cost-effective. Conclusion: No evidence currently exists on whether there are health benefits associated with imaging improvements from the use of EOS{sup ®}. The health benefits from radiation dose reductions are very small. Unless EOS{sup ®} can generate additional health benefits as a consequence of the nature and quality of the image, comparative patient throughput with X-ray will be the major determinant of cost-effectiveness.

  17. Maximizing the use of EO products: how to leverage the potential of open geospatial service architectures

    2012-10-01

    The demand for the rapid provision of EO products with well-defined characteristics in terms of temporal, spatial, image-specific and thematic criteria is increasing. Examples are products to support near real-time damage assessment after a natural disaster event, e.g. an earthquake. However, beyond the organizational and economic questions, there are technological and systemic barriers to enable a comfortable search, order, delivery or even combination of EO products. Most portals of space agencies and EO product providers require sophisticated satellite and product knowledge and, even worse, are all different and not interoperable. This paper gives an overview about the use cases and the architectural solutions that aim at an open and flexible EO mission infrastructure with application-oriented user interfaces and well-defined service interfaces based upon open standards. It presents corresponding international initiatives such as INSPIRE (Infrastructure for Spatial Information in the European Community), GMES (Global Monitoring for Environment and Security), GEOSS (Global Earth Observation System of Systems) and HMA (Heterogeneous Missions Accessibility) and their associated infrastructure approaches. The paper presents a corresponding analysis and design methodology and two examples how such architectures are already successfully used in early warning systems for geo-hazards and toolsets for environmentallyinduced health risks. Finally, the paper concludes with an outlook how these ideas relate to the vision of the Future Internet.

    Full Text Available Este estudo trata-se de revisão integrativa da literatura com objetivo de sintetizar o conhecimento produzido em artigos sobre os cuidados de enfermagem aos pacientes em pós-operatório de prostatectomia. Para seleção dos artigos foram consultadas cinco bases de dados – SCOPUS, CINAHL, PUBMED, LILACS e Cochrane – sendo incluídos dezenove artigos. Os resultados mostram estudos que se enquadram nos níveis II, IV, V, VI e VII de evidência, a maioria realizada nos Estados Unidos durante os anos de 1999 a 2011. Os cuidados de enfermagem identificados foram agrupados em seis categorias: acompanhamento psicológico, orientações pós- operatórias, tratamento da disfunção erétil, tratamento da incontinência urinária, tratamento da dor e tratamento da hiponatremia. Conclui-se que os estudos com maior nível de evidência identificado recomendam cuidados de enfermagem centrados no acompanhamento psicológico, nas orientações do período pós-operatório e no tratamento da disfunção erétil. Destaca-se ainda que tais recomendações concentram-se, sobretudo, nas ações de apoio emocional e educativo.

    Organotin compounds are chemicals that are widely used in industry and agriculture as plastic stabilizers, catalysts and biocides. Many of them, including tributyltin (TBT), have been detected in human food and, as a consequence, detectable levels have been found in human blood. As organotin compounds were shown to possess immunotoxic activity, we focused our attention on the effect of TBT on the basic determinants of the function of eosinophils, i.e. cell adhesiveness and motility. We used human eosinophylic leukemia EoL-1 cells, a common in vitro cellular model of human eosinophils. Here, we demonstrate that TBT causes a dose-dependent decrease in the viability of EoL-1 cells. When administered at sub-lethal concentrations, TBT significantly decreases the adhesion of EoL-1 cells to human fibroblasts (HSFs) and inhibits their migration on fibroblast surfaces. Since the basic function of eosinophils is to invade inflamed tissues, our results indicate that TBT, and possibly other organotin compounds, may affect major cellular properties involved in the determination of in vivo eosinophil function.

  3. Training for Defense? From Stochastic Traits to Synchrony in Giant Honey Bees (<em>Apis dorsataem>

    Full Text Available In Giant Honey Bees, abdomen flipping happens in a variety of contexts. It can be either synchronous or cascaded, such as in the collective defense traits of shimmering and rearing-up, or it can happen as single-agent behavior. Abdomen flipping is also involved in flickering behavior, which occurs regularly under quiescent colony state displaying singular or collective traits, with stochastic, and (semi- synchronized properties. It presumably acts via visual, mechanoceptive, and pheromonal pathways and its goals are still unknown. This study questions whether flickering is preliminary to shimmering which is subject of the <em>fs em>(flickering-shimmering-transition> hypothesis? We tested the respective prediction that trigger sites (<em>ts> at the nest surface (where shimmering waves had been generated show higher flickering activity than the alternative non-trigger sites (<em>nts>. We measured the flickering activity of <em>ts>- and <em>nts>-surface bees from two experimental nests, before and after the colony had been aroused by a dummy wasp. Arousal increased rate and intensity of the flickering activity of both <em>ts>- and <em>nts> cohorts (P < 0.05, whereby the flickering intensity of <em>ts>-bees were higher than that of <em>nts>-bees (P < 0.05. Under arousal, the colonies also increased the number of flickering-active <em>ts>- and <em>nts>-cohorts (P < 0.05. This provides evidence that cohorts which are specialist at launching shimmering waves are found across the quiescent nest zone. It also proves that arousal may reinforce the responsiveness of quiescent curtain bees for participating in shimmering, practically by recruiting additional trigger site bees for expanding repetition of rate and intensity of shimmering waves. This finding confirms the <em>fs-transition> hypothesis and constitutes evidence that flickering is part of a basal colony-intrinsic information system

    Full Text Available <p>Abstract
    Any hypothesis aiming to explain the social organisation of Eurasian badgers <em>Meles melesem> has to consider its wide inter-population variability. We used radiotracking techniques to investigate the spatial organisation and the pattern of space-use by badger in Luxembourg, where badger density can be considered moderate compared to most of Europe.
    Eight badgers belonging to five social groups were caught and radio-collared. The size of individual home ranges, as assesses by 100% minimum convex polygons in spring-summer 2002 and 2003, varied from 42.5 ha to 171.8 ha. Core areas corresponded to the 50-70% kernel isopleths and covered an average of 10.1% of individual home ranges. The home ranges of badgers caught at the same sett overlapped largely (average 83.3%, whilst the overlap between neighbouring ranges did not exceed 13.8%. Altogether six boundary latrines were found at the intersection of group ranges. Overall, the spatial system of the Luxembourg badgers is quite flexible, with the boundaries of some group ranges remaining constant over the years, while others may expand or contract.

Foram obtidos bons resultados em 20 casos com nítida melhora na sintomatologia psíquica. Os efeitos colaterais foram de pequena intensidade. Os exames subsidiários (hemograma, provas de função hepática e eletrencefalograma não revelaram alterações significativas. Assim o tietixene confirmou sua atividade antipsicótica não só nos casos em que foi o primeiro tratamento instituído como também em alguns pacientes que tinham sido tratados com outras drogas antipsicóticas sem resultados satisfatórios. Foi assinalado efeito nítido sobre o apragmatismo e o embotamento afetivo. Ocorreu ação sedativa nas agitações psicomotoras devendo-se salientar que o resultado positivo se fez quase sempre sentir com dose mínima (5 — 10 mg/dia já nos primeiros dias de tratamento. Foi ótima a tolerância ao medicamento. Os efeitos colaterais foram mínimos. Sendo a esquizofrenia em crianças e adolescentes de difícil tratamento, a existência desta nova droga é, na opinião dos autores, uma util contribuição para sua terapêutica.

Para isto, estudou-se 56 pacientes, com idade média de 39 anos, sendo 37 homens e 19 mulheres. As principais indicações para a colostomia foram ferimento por arma de fogo (35%, doença diverticular perfurada (12,5% e câncer colo-retal (12%. O tipo de colostomia mais realizado foi terminal (70%, com utilização do sigmóide em 71,4% dos casos. O tempo médio de permanência da colostomia foi de 5,5 meses. A reconstrução do trânsito foi realizada através de anastomose término-terminal em 85,7% dos pacientes, através de síntese mecânica com stapler circular em 5 pacientes ou manual em 51 pacientes. Observou-se taxa de complicações de 25%, sendo as mais frequentes a infecção de parede (35,7%, as fístulas (28,6% e a hemorragia digestiva baixa (21,4%. Conclui-se que a reconstrução do trânsito intestinal não está isenta de riscos cirúrgicos e apresenta taxas consideráveis de complicações pós-operatórias, sendo que a infecção continua a ser um dos maiores desafios existentes neste procedimento.

    Highlights: • Diffusion and gradual solid reactions between Al and Fe{sub x}P phases in Al-Fe-P alloy were investigated. • Nanoscale AlP clusters are in-situ generated and evolve during the whole process. • This novel Al-Fe-P alloy has an excellent low-temperature refining performance on hypereutectic Al-Si alloy. - Abstract: In this paper, the gradual solid reactions between Al and Fe{sub x}P phases in Al-Fe-P alloy were investigated. The results show that the whole reaction process undergoes four main stages: the diffusion of Al atom, the generation of (Al, Fe, P) intermediate compound, the precipitation of nano AlP and Al{sub 13}Fe{sub 4} clusters and their growth to submicron particles. The microstructure of Fe-P particles evolves from the “egg-type”, the “sponge-type” to the “sesame-cake” structure. AlP and Al{sub 13}Fe{sub 4} nano phases have in-situ generated and evolved during the whole process. The gradual reaction mechanism has been discussed. Furthermore, a novel Al-Fe-P alloy which contains (Al, Fe, P) intermediate compounds and nano AlP particles has been synthesized and its low-temperature refining performance on A390 alloy has also been investigated.

    Full Text Available Compostos secundários presentes em plantas medicinais desempenham funções importantes em interações planta-patógeno, por ação antimicrobiana direta ou induzindo a síntese de mecanismos de defesa em outras plantas. Para verificar o efeito fungitóxico do eucalipto sobre o crescimento micelial de Rhizoctonia solani, Sclerotium rolfsii, Phytophthora sp, Alternaria alternata e Colletotrichum sublineolum, o extrato bruto (EB foi incorporado ao BDA e o óleo essencial (OE foi distribuído na superfície do meio com alça de Drigalski. A germinação de esporos de C. sublineolum também foi avaliada na presença de diferentes alíquotas de OE. Para verificar a indução de fitoalexinas, mesocótilos de sorgo foram aspergidos com EB a 20% ou então, mergulhados em suspensões do OE. Para a indução de gliceolina, 20 µL do EB foram colocados em cotilédones de soja. A presença de compostos fungitóxicos no OE e EB através da cromatografia de camada delgada também foi avaliada. Os resultados evidenciaram inibição do crescimento micelial dos fungos para concentrações do EB acima de 20%. Todas as alíquotas do óleo inibiram o crescimento micelial dos fungos testados, com exceção de R. solani cuja inibição ocorreu para alíquotas acima de 20µL. Houve inibição de 100% na germinação dos conídios para todas as alíquotas do OE testadas na primeira metodologia, porém, na segunda metodologia o OE não promoveu inibição da germinação de esporos. Entretanto, foram observadas alterações na morfologia dos tubos germinativos e inibição da formação de apressórios. Observou-se a presença de apenas uma fração fungitóxica no OE, e o EB não apresentou frações fungitóxicas. Houve a produção de fitoalexinas apenas em mesocótilos de sorgo tratados com o EB.Secondary compounds found in medicinal plants play important role in plant-pathogen interactions by having direct antimicrobian effect on them or inducing the defense

    Arg13 is a conserved active-site residue in all known Pi class glutathione S-transferases (GSTs) and in most Alpha class GSTs. To evaluate its contribution to substrate binding and catalysis of this residue, three mutants (R13A, R13K, and R13L) were expressed in Escherichia coli and purified by GSH affinity chromatography. The substitutions of Arg13 significantly affected GSH-conjugation activity, while scarcely affecting glutathione peroxidase or steroid isomerase activities. Mutation of Arg13 into Ala largely reduced the GSH-conjugation activity by approximately 85 - 95%, whereas substitutions by Lys and Leu barely affected activity. These results suggest that, in the GSH-conjugation activity of hGST P1-1, the contribution of Arg13 toward catalytic activity is highly dependent on substrate specificities and the size of the side chain at position 13. From the kinetic parameters, introduction of larger side chains at position 13 results in stronger affinity (Leu > Lys, Arg > Ala) towards GSH. The substitutions of Arg13 with alanine and leucine significantly affected k cat , whereas substitution with Lys was similar to that of the wild type, indicating the significance of a positively charged residue at position 13. From the plots of log (k cat /K m CDNB ) against pH, the pK a values of the thiol group of GSH bound in R13A, R13K, and R13L were estimated to be 1.8, 1.4, and 1.8 pK units higher than the pK a value of the wildtype enzyme, demonstrating the contribution of the Arg13 guanidinium group to the electrostatic field in the active site. From these results, we suggest that contribution of Arg13 in substrate binding is highly dependent on the nature of the electrophilic substrates, while in the catalytic mechanism, it stabilizes the GSH thiolate through hydrogen bonding

    Full Text Available In this paper, roots of arracacha (Arracacia xanthorrhyza Bancroft were stored at 5ºC to induce chilling injury symptoms and stress-related peroxidase activity. Later, peroxidase kinetic activity was determined in different pH and temperature conditions. For this, soluble crude extract was sequentially saturated with ammonium sulfate, obtaining a semi-purified enzyme solution used for the analysis. Activity of peroxidase induced by the chilling at 5oC was determined from pH 2.5 to 9.0 and at temperature ranging from 10 to80oC. The peroxidase had higher activity when the reaction occurred between pH 5.5 and 6.0 and at temperature of 30oC. Complete inactivation of the activity was observed in pH 2.5 after 60 minutes of pre-incubation or at 60oC for 10 minutes or alternatively at 70oCafter 5 minutes of pre-incubation. The enzyme is more susceptible to inactivation in acid than alkaline pHs or alternatively using heat treatment.Neste trabalho, raízes de batata-baroa (Arracacia xanthorrhiza Bancroft foram armazenadas a 5oC para induzir injúria por frio e expressar atividade da peroxidase de estresse.

    High-harmonic-generation (HHG) based seeded FEL experiments were demonstrated at SCSS, SPring-8. Seeded FEL has advantageous features against SASE such that there is no intrinsic nature of shot-noise fluctuation and output FEL pulses are in principle fully coherent in both transverse and longitudinal axes. In practical user experiments, however, an overlap between electron bunches and seed laser pulses in six-dimensional phase space needs to be precisely maintained for securing the stable lasing. Otherwise, the overlap could be quickly lost and the lasing is no more sustained. For the stable lasing, we have developed an EO (electro-optic) based timing control system, which enables to observe a timing drift between electron bunches and laser pulses, and compensate for it. Experimental results of the seeded FEL with and without the EO timing control are compared, and the effectiveness of the timing system is discussed. (author)

    Caspases are key molecules in the control of apoptosis, but relatively little is known about their contribution to eosinophil apoptosis. We examined caspase-3, -8, and -9 activities in receptor ligation-dependent apoptosis induction in the differentiated human eosinophilic cell line EoL-1. Differentiated EoL-1 exhibited bi-lobed nuclei, eosinophil-associated membrane receptors, and basic granule proteins. Annexin-V fluorescein isothiocyanate binding to EoL-1 revealed significant (PEoL-1 but had no effect on constitutive (baseline) apoptosis at 16 and 20 h. Caspase activity was analyzed using the novel CaspaTag trade mark technique and flow cytometry. EoL-1 treated with pan-CD45, CD45RA, CD45RB, and CD95 mAb exhibited caspase-3 and -9 activation at 12 h post-treatment, which increased at 16 and 20 h. Activated caspase-8 was detected 12 and 16 h after ligation with CD45, CD45RA, CD45RB, and CD95 mAb followed by a trend toward basal levels at 20 h. CD69 ligation resulted in caspase-3 activation, a modest but significant activation of caspase-8, and a loss in mitochondrial transmembrane potential but had no significant effect on activation of caspase-9. Thus, the intrinsic and extrinsic caspase pathways are involved in controlling receptor ligation-mediated apoptosis induction in human eosinophils, findings that may aid the development of a more targeted, anti-inflammatory therapy for asthma.

    CryoEM continues to produce density maps of larger and more complex assemblies with multiple protein components of mixed symmetries. Resolution is not always uniform throughout a cryoEM map, and it can be useful to estimate the resolution in specific molecular components of a large assembly. In this study, we present procedures to 1) estimate the resolution in subcomponents by gold-standard Fourier shell correlation (FSC); 2) validate modeling procedures, particularly at medium resolutions, which can include loop modeling and flexible fitting; and 3) build probabilistic models that combine high-accuracy priors (such as crystallographic structures) with medium-resolution cryoEM densities. As an example, we apply these methods to new cryoEM maps of the mature bacteriophage P22, reconstructed without imposing icosahedral symmetry. Resolution estimates based on gold-standard FSC show the highest resolution in the coat region (7.6 Å), whereas other components are at slightly lower resolutions: portal (9.2 Å), hub (8.5 Å), tailspike (10.9 Å), and needle (10.5 Å). These differences are indicative of inherent structural heterogeneity and/or reconstruction accuracy in different subcomponents of the map. Probabilistic models for these subcomponents provide new insights, to our knowledge, and structural information when taking into account uncertainty given the limitations of the observed density.

    Accurate simulations of fluid and plasma flows require accurate thermodynamic properties of the fluids or plasmas. This thermodynamic information is represented by the equations of state of the materials. For pure materials, the equations of state may be represented by analytical models for idealized circumstances, or by tabular means, such as the Sesame tables. However, when a computational cell has a mixture of two or more fluids, the equations of state are not well understood, particularly under the circumstances of high energy densities. This is a particularly difficult issue for Eulerian codes, wherein mixed cells arise simply due to the advection process. LANL Eulerian codes typically assume an “Amagat’s Law” (or Law of Partial Volumes) for the mixture in which the pressures and temperatures of fluids are at an equilibrium that is consistent with the fluids being segregated within the cell. However, for purposes of computing other EOS properties, e.g., bulk modulus, or sound speed, the fluids are considered to be fully “mixed”. LANL has also been investigating implementing instead “Dalton’s Law” in which the total pressure is considered to be the sum of the partial pressures within the cell. For ideal gases, these two laws give the same result. Other possibilities are nonpressure- temperature-equilibrated approaches in which the two fluids are not assumed to “mix” at all, and the EOS properties of the cell are computed from, say, volume-weighted averages of the individual fluid properties. The assumption of the EOS properties within a mixed cell can have a pronounced effect on the behavior of the cell, resulting in, for example, different shock speeds, pressures, temperatures and densities within the cell. There is no apparent consensus as to which approach is best under HED conditions, though we note that under typical atmospheric and near atmospheric conditions the differences may be slight.

    EarthScope's education and outreach (E&O) mission is to ensure that the EarthScope experiment creates as its legacy a public more knowledgeable and understanding of the scientific and societal contributions made by the EarthScope experiment and Earth science. It will fulfill this commitment by developing and disseminating programs and products that utilize the data, models, technology and discoveries of EarthScope. The EarthScope Education and Outreach Network (EON), consisting of local EON alliances, the EarthScope facilities, partner organizations and a coordinating office, will facilitate this E&O mission. The local EON alliances, which will vary in size and purpose to respond quickly and to meet the specific needs in a region, will carry out the bulk of the effort. Thus, EarthScope EON can provide customized services that engage culturally, economically and geographically diverse audiences at the national and local scales. The EarthScope facilities and research community will provide access to data, models, and visualization tools for educational purposes. Partnerships with other national and local science education and outreach programs at colleges, universities, research facilities and professional societies within the EarthScope community as well as relevant programs at museums and parks, state geologic surveys and emergency management agencies, and K-12 schools are critical to EON's success. These partnerships will allow EON to use existing resources, networks and expertise to gear up quickly and efficiently. As EON develops, it will reciprocate by contributing new resources and expertise to the partnerships that help improve public understanding of Earth systems overall and promote effective application of EarthScope discoveries. In this presentation, we will outline major programs and products envisioned for EarthScope, plans for evaluating those programs locally and nationally, and mechanisms for collaborating with existing E&O programs.

    Effects of a homologous series of three primarily linear alcohol ethoxylate surfactants were studied in laboratory flow-through 28-day early-life-stage tests with fathead minnow (Pimephales promelas Rafinesque). Surfactants were a C(9-11), C(12-13), and C(14-15) with an average of 6, 6.5, and 7 ethylene oxide units per mole of alcohol, respectively. Average measured surfactant recoveries were 103%, 81%, and 79% of nominal concentrations for the C(9-11) EO 6, C(12-13) EO 6.5, and C(14-15) EO 7 studies, respectively. Embryo survival at 48 h was not adversely affected at any of the concentrations tested. Impaired hatching and deformed fry were observed only in the C(12-13) EO 6.5 study. The 28-day LC50 values were 4.87, 2.39, and 1.02 mg/L for the C(9-11) EO 6, C(12-13) EO 6.5, and C(14-15) EO 7 surfactants, respectively. The corresponding NOECs for survival were 1.01, 1.76, and 0.74 mg/L. Posthatch fry growth was more sensitive than survival for the C(12-13) EO 6.5 and C(14-15) EO 7 surfactants. Survival of posthatch fry decreased with increasing surfactant alkyl chain length. Twenty-eight-day laboratory data were compared to 96-h laboratory, 10-day laboratory and 30-day stream mesocosm data for fathead minnow previously determined for these surfactants. Survival endpoints from the different exposures were comparable and only varied within a factor of two. Similarity of results suggests that it is possible to effectively use 96-h, 10-day, or 28-day laboratory data to predict environmental effects concentrations of these surfactants for fish. http://link.springer-ny. com/link/service/journals/00244/bibs/37n4p536.html

    Full Text Available Será que o crescimento de uma sociedade civil global é um processo cumulativo, ou estamos apenas presenciando o afloramento transnacional de uma série de Estados? Colocando essa pergunta de forma mais geral: "Será que a tradicional divisão entre políticas nacionais e internacionais está se decompondo?" Grande parte do futuro do ativismo social e transnacional depende dessa pergunta. Neste artigo, ilustrarei primeiro esse dilema referindo a história atual e conhecida: os protestos em relação à Tocha Olímpica, em Londres e Paris, e suas relações com o Tibete e Darfur, indagando o que isso nos diz em relação à natureza do ativismo transnacional público. Em seguida construirei uma tipologia de formas de interação nacional e transacional entre os atores públicos não estatais. Posteriormente, passarei a realizar uma previsão do futuro, com alguma prudência, do que alguns intitulam "sociedade civil global" e de como ela pode afetar o ativismo transnacional.

From each individual we extracted a strip of muscle from the region above the lateral line, in the dorsal fin base, that was divided into three equal parts, each one was submitted to one type of treatment: freeze . control group (-15oC, conservation in alcohol 70%and fixation in formaldehyde 4%. Samples were kept under those treatments for 30 days, washed and submerged in distilled water for 4 hours. Afterwards, they were dried up in air oven at 60oC for 48 hours and macerated until the obtaining of a fine powder. A significant difference was found in isotopic values of carbon and nitrogen, between the control and the samples in alcohol and formaldehyde, except for ƒÂ13C from the H. edentatus samples in formaldehyde. The carbon isotopic values of samples in alcohol were mostly enriched compared to control, whereas the samples in formaldehyde presented depleted values in relation to the control. The nitrogen isotopic values for both samples preserved in alcohol and formaldehyde were enriched when compared to the values of frozen samples, independently of used preservatives. Therefore, the isotopic correction should be accomplished according to the isotope and preservative employed for species of freshwater fish.O presente estudo investiga a composicao isotopica de ƒÂ13C e ƒÂ15N entre as amostras congeladas (controle, em alcool e em formol de Plagioscion squamosissimus e Hypophthalmus edentatus.

  7. Normal pregnancy: mechanisms underlying the paradox of a ouabain-resistant state with elevated endogenous ouabain, suppressed arterial sodium calcium exchange, and low blood pressure

    Endogenous cardiotonic steroids (CTS) raise blood pressure (BP) via vascular sodium calcium exchange (NCX1.3) and transient receptor-operated channels (TRPCs). Circulating CTS are superelevated in pregnancy-induced hypertension and preeclampsia. However, their significance in normal pregnancy, where BP is low, is paradoxical. Here we test the hypothesis that vascular resistance to endogenous ouabain (EO) develops in normal pregnancy and is mediated by reduced expression of NCX1.3 and TRPCs. We determined plasma and adrenal levels of EO and the impact of exogenous ouabain in pregnancy on arterial expression of Na+ pumps, NCX1.3, TRPC3, and TRPC6 and BP. Pregnant (embryonic day 4) and nonpregnant rats received infusions of ouabain or vehicle. At 14–16 days, tissues and plasma were collected for blotting and EO assay by radioimmunoassay (RIA), liquid chromatography (LC)-RIA, and LC-multidimensional mass spectrometry (MS3). BP (−8 mmHg; P vs. nonpregnant (0.6 ± 0.08 nM; P endogenous and exogenous ouabain is mediated by suppressed NCX1.3 and reduced sensitivity of events downstream of Ca2+ entry. The mechanisms of EO resistance and the impaired fetal and placental growth due to elevated ouabain may be important in pregnancy-induced hypertension (PIH) and preeclampsia (PE). PMID:22245773

No universo narrativo do game, X é único robô a possuir a capacidade de ter sentimentos, sendo seu projeto o ponto de partida para a criação dos reploids (cyborgs com a capacidade de livre arbítrio, que, como ele,demonstram empatia por todos os seres, sejam humanos ou robóticos. Apesar de X ter o que é considerada a maior “fraqueza” dos humanos: sentimentos, ele é o personagem mais poderoso da série, justamente pela percepção de que esse potencial o torna ilimitado como os humanos; pois enquanto os humanos são capazes de evoluir física e intelectualmente, os robôs estarão permanentemente atrelados à função para a qual foram criados.

Analisaram-se, por meio de questionários e da observação, aspectos sobre a estrutura, as atividades complementares do programa, o perfil das merendeiras, os conhecimentos sobre alimentação e nutrição dos professores e a aceitação da alimentação escolar. Resultados: As condições estruturais tiveram avaliação média regular, estando oito escolas (44,44% classificadas nessa categoria e sendo os itens refeitório e área da cozinha os mais deficitários. Constatou-se um déficit de ações complementares ao programa; apenas duas escolas (11,11% tinham horta escolar e cinco (27,77% desenvolviam atividades de saúde e nutrição. Entre as merendeiras, destacou-se um perfil adequado ao exercício da profissão. Na avaliação dos conhecimentos dos professores, a identificação das características nutricionais dos alimentos foi a principal falha constatada. A rejeição e a não adesão à alimentação escolar foram estimados em torno de 25% e 35% dos escolares, respectivamente. Conclusão: Apontam-se falhas estruturais e processuais na execução do PNAE que precisam ser sanadas em cumprimento às leis vigentes. Destacam-se deficiências no refeitório, na cozinha e no desenvolvimento de atividades educativas. Além disso, hortas escolares foram escassas. Melhorias nessas condições podem repercutir positivamente na aceitação e adesão dos escolares à alimentação escolar.

    2004-01-01

    As part of the Earth Observer 1 (EO-1) Mission, the Advanced Land Imager (ALI) demonstrates a potential technological direction for Landsat Data Continuity Missions. To evaluate ALI's capabilities in this role, a cross-calibration methodology has been developed using image pairs from the Landsat-7 (L7) Enhanced Thematic Mapper Plus (ETM+) and EO-1 (ALI) to verify the radiometric calibration of ALI with respect to the well-calibrated L7 ETM+ sensor. Results have been obtained using two different approaches. The first approach involves calibration of nearly simultaneous surface observations based on image statistics from areas observed simultaneously by the two sensors. The second approach uses vicarious calibration techniques to compare the predicted top-of-atmosphere radiance derived from ground reference data collected during the overpass to the measured radiance obtained from the sensor. The results indicate that the relative sensor chip assemblies gains agree with the ETM+ visible and near-infrared bands to within 2% and the shortwave infrared bands to within 4%.

    Highlights: → Extended PR-EOS was presented for VLE of H 2 O/Salt/CO 2 systems at high pressure. → The proposed EPR-EOS is based upon contributions to the Helmholtz energy. → Born, Margules, and Debye-Huckel or mean spherical approximation terms were used. → Two different mixing rules Panagiotopoulos and Reid and Kwak and Mansoori (KM) were used. → A combination of KM mixing rule with DH term results more accurate VLE results. - Abstract: A modification of the extended Peng-Robinson equation of state (PR-EOS) is presented to describe the (vapour + liquid) equilibria of systems containing water and salts. The modification employs three additional terms including a Born term, a Margules term and two terms separately used for estimation of the long-range electrostatic interactions (the Debye-Huckel (DH) or the mean spherical approximation (MSA) terms). Effects of two mixing rules, first, the Panagiotopoulos and Reid mixing rule (PR) and, second, the Kwak and Mansoori mixing rule (KM), on the final values of VLE calculations are also investigated. The results show that the KM mixing rule is more appropriate than the PR mixing rule. The proposed equation of state is used to calculate the (vapour + liquid) equilibrium (VLE) of the systems containing (water + sodium sulphate + carbon dioxide) and (water + sodium chloride + carbon dioxide) at high pressure. The comparison of calculated results with the experimental data shows that a combination of KM mixing rule with the DH term results a more accurate VLE values.

    This report gives the result of a bilateral comparison of resistance between the NSAI NML (Ireland) and the BIPM carried out in 2014-2015. Two 1 Ω and two 10 kΩ travelling standards belonging to the BIPM were used. The comparison was carried out with an 'A-B-A' pattern of measurements; the standards were measured first at the BIPM for a period of about one month, then for a similar period at the NSAI-NML, and finally again at the BIPM. The measurand was the 4 terminal dc resistance at low power. The BIPM was the pilot laboratory, and the comparison forms part of the ongoing BIPM key comparisons BIPM.EM-K13.a (for 1 Ω) and BIPM.EM-K13b (for 10 kΩ). The results from the NSAI NML and the BIPM were found to be in good agreement, with a difference smaller than the relative expanded uncertainties (95% confidence, k = 2) of 0.16 × 10-6 for 1 Ω and 0.42 × 10-6 for 10 kΩ.

    Full Text Available This paper presents an evaluation of the performance of cubic equations of state in the prediction of the phase behavior of hyperbaric mixtures. It points out a number of problems that should be resolved in a cooperative way. Items related to EoS parameter definitions such as interaction coefficients, critical properties of hydrocarbon compounds and volume translation are investigated. VLE experimental data, isothermal flash compositional and volumetric data up to 4000 bar as well as PVT data up to 2000 bar for binary mixtures and synthetic multicomponent systems have been considered in this study. Correlation and prediction results are presented with the translated and modified Peng-Robinson (t-mPR EoS. It is shown that serious problems are encountered at high pressure, when extrapolated interaction coefficients are used. Prediction of saturation pressures of gas condensates is more satisfactory when binary interaction parameters are obtained from high pressure dew point correlations. Compositional and volumetric predictions are remarkable under the assumption that definition of the EoS parameters is based on high pressure VLE binary data. Contradictory results are obtained with different methods for estimating the critical properties of high molecular weight hydrocarbons. Generalized expressions for the volume translation appear to be very efficient even at very high temperatures and pressures (up to 2000 bar.

    Full Text Available Em ecossistemas de pastagens naturais deficientes em P disponível, a imobilização temporária do P na biomassa microbiana e sua posterior mineralização podem ser considerados mecanismo potencial de suprimento de P às plantas. O objetivo deste trabalho foi avaliar a influência da queima e do pastejo da vegetação campestre sobre a dinâmica do P no solo, com ênfase no conteúdo de P imobilizado na biomassa microbiana. Os tratamentos consistiram da associação do pastejo (presença ou ausência e da queima (ausência ou presença numa pastagem natural manejada há 13 anos com histórico de queimadas e de pastejo nas posições de relevo de encosta (Argissolo e de baixada (Planossolo. A queima e o pastejo foram arranjados em delineamento completamente casualizado com quatro repetições. Coletaram-se amostras de solo na camada de 0-10 cm em duas épocas, durante a estação de crescimento da pastagem natural, sempre logo após o pastejo. A carga animal utilizada foi calculada adotando-se uma taxa de utilização de 20-35 % da massa de forragem. Determinaram-se o teor de P armazenado na biomassa microbiana do solo, o teor de P total e o de P orgânico total. A análise estatística dos resultados foi baseada em análise de variância via testes de aleatorização. O teor de P microbiano do solo sob pastagem natural variou de 11,4 a 57,3 mg kg-1, representando, em média, 38 e 32 % do P orgânico total do solo, na primeira e na segunda coleta, respectivamente. O P imobilizado na biomassa microbiana constitui a reserva potencial de P capaz de suprir a demanda de espécies nativas nas pastagens naturais, além de ser indicador mais sensível que o teor de P orgânico total do solo para detectar as alterações promovidas pelo pastejo. O manejo das pastagens naturais com fogo diminui a amplitude do incremento de P microbiano decorrente do pastejo.

    Full Text Available Resumo Aconselhamento em contracepção e oferta de insumos contraceptivos são parte da atenção pós-abortamento e influenciam positivamente o uso de métodos contraceptivos. Estudos que mostram tais evidências são realizados, predominantemente, em países sem restrições legais ao aborto e com adequada atenção às mulheres que interrompem a gravidez. No entanto, pouco se sabe a respeito das práticas contraceptivas em contextos de ilegalidade do aborto, caso do Brasil, em que a atenção em contracepção pós-abortamento é inadequada. O objetivo foi analisar o efeito da atenção em contracepção no uso de preservativo masculino, anticonceptivo oral e injetável nos seis meses pós-abortamento, considerando a intenção reprodutiva. Os resultados mostraram que a atenção em contracepção tem efeito positivo apenas sobre o uso do anticonceptivo oral nos seis meses pós-abortamento, desde que a mulher tenha passado por consulta médica no mesmo mês em que recebeu orientações sobre contracepção. Uma ou outra ação não tem efeito significativo quando ocorre isoladamente.

    2015-01-01

    The development of biologic drugs has undoubtedly enhanced the spectrum of treatments available for immune-mediated inflammatory rheumatic diseases such as rheumatoid arthritis. However, despite their clear clinical benifits, use of biologics is often hindered by their high costs. The manufacture and subsequent approval of more cost-effective 'biosimilar' versions of these drugs may address this issue and improve patient access. CT-P13 (Remsima(®), Inflectra(®)), a biosimilar of infliximab (Remicade(®)), has shown comparable efficacy, safety and pharmacokinetics to its originator drug in clinical studies. The articles in this supplement present a scientific update on the development and use of biosimilars in rheumatic disorders, with specific focus on CT-P13. The information discussed highlights the predicted positive clinical and economic impact of biosimilars on the management of rheumatic diseases.

    The FP6 (Sixth Framework Program of the European Union) team of PricewaterhouseCoopers has analysed the EoIs (Expression of Interest) submitted by Dutch parties, as published on the Internet (http://www.cordis.lu/). These 'Dutch EoIs' give a reliable indication of the focus of the Dutch research community, and its participation in pan-European research initiatives. Furthermore, it gives the Dutch submitters of EoIs the opportunity to see what other Dutch parties are involved in their relevant area of research (or in terms of FP6 - Thematic Priority Area (TPA)). The analysis of the Dutch EoIs has been carried out in the first week of October 2002. Considering the dynamics of the EoI database, results from this analysis can vary slightly with searches carried out later in this database

    Here we report a patient with 11p15.4p15.5 duplication and 13q34 deletion presenting with Beckwith-Wiedemann syndrome (BWS) and moderate deficiency of factor VII (FVII). The duplication was initially diagnosed on methylation-sensitive multiplex ligation-dependent probe amplification. Array comparative genome hybridization confirmed its presence and indicated a 13q34 distal deletion. The patient's clinical symptoms, including developmental delay and facial dysmorphism, were typical of BWS with paternal 11p15 trisomy. Partial 13q monosomy in this patient is associated with moderate deficiency of FVII and may also overlap with a few symptoms of paternal 11p15 trisomy such as developmental delay and some facial features. To our knowledge this is the first report of 11p15.4p15.5 duplication associated with deletion of 13q34 and FVII deficiency. Moreover, this report emphasizes the importance of detailed clinical as well as molecular examinations in patients with BWS features and developmental delay. © 2015 Japan Pediatric Society.

    Full Text Available The P13 potential is the rodent equivalent of the P50 potential, which is an evoked response recorded at the vertex (Vx 50 msec following an auditory stimulus in humans. Both the P13 and P50 potentials are only present during waking and rapid eye movement (REM sleep, and are considered to be measures of level of arousal. The source of the P13 and P50 potentials appears to be the pedunculopontine nucleus (PPN, a brainstem nucleus with indirect ascending projections to the cortex through the intralaminar thalamus (ILT, mediating arousal, and descending inhibitory projections to the caudal pontine reticular formation (CPRF, which mediates the auditory startle response (SR. We tested the hypothesis that intracranial microinjection (ICM of glutamate (GLU or GLU receptor agonists will increase the activity of PPN neurons, resulting in an increased P13 potential response, and decreased SR due to inhibitory projections from the PPN to the CPRF, in freely moving animals. Cannulae were inserted into the PPN to inject neuroactive agents, screws were inserted into the Vx in order to record the P13 potential, and electrodes inserted into the dorsal nuchal muscle to record electromyograms (EMGs and SR amplitude. Our results showed that ICM of GLU into the PPN dose-dependently increased the amplitude of the P13 potential and decreased the amplitude of the SR. Similarly, ICM of NMDA or KA into the PPN increased the amplitude of the P13 potential. These findings indicate that glutamatergic input to the PPN plays a role in arousal control in vivo, and changes in glutamatergic input, or excitability of PPN neurons, could be implicated in a number of neuropsychiatric disorders with the common symptoms of hyperarousal and REM sleep dysregulation.

    Full Text Available Sintomas sugestivos do comprometimento do tubo digestivo são comuns em pacientes diabéticos, mas estudos comparando as freqüências destes sintomas com as da população geral são escassos e não existem trabalhos dessa natureza com diabéticos brasileiros. OBJETIVO: Determinar as freqüências de diferentes sintomas digestivos em amostra não selecionada de pacientes diabéticos, em comparação às encontradas em pessoas da comunidade. MÉTODOS: A ocorrência de 13 diferentes sintomas digestivos foi investigada por meio da aplicação de um questionário padronizado, especificamente estruturado, em 153 diabéticos dos tipos 1 e 2 e em 50 pessoas aparentemente sadias, tomadas como controles. RESULTADOS: A freqüência de diabéticos com pelo menos um sintoma digestivo foi significativamente superior à verificada no grupo controle (70% vs 36%, p = 0,01. Freqüências elevadas de plenitude gástrica (30% vs 36%, pirose (30% vs 34% e de constipação (17% vs 12%, foram observadas tanto entre os diabéticos como nos controles. No entanto, somente a freqüência de um único sintoma, a disfagia, foi significativamente maior entre os diabéticos, em relação ao grupo controle (13% vs 2%, p = 0,02. CONCLUSÃO: Estes resultados indicam que a freqüência de sintomas digestivos em diabéticos, apesar de elevada, não difere da verificada na população geral, exceto para a disfagia. As freqüências dos diferentes sintomas estiveram próximas das faixas relatadas em estudos do hemisfério Norte, o que não apóia a hipótese de que fatores inerentes ao meio afetam a ocorrência de queixas digestivas em diabéticos.PURPOSE: To determine the frequencies of digestive symptoms in an unselected sample of Brazilian diabetics, in comparison to those verified in the general population.

    Eos (Extensible object-oriented system) is one of the powerful applications for image processing of electron micrographs. In usual cases, Eos works with only character user interfaces (CUI) under the operating systems (OS) such as OS-X or Linux, not user-friendly. Thus, users of Eos need to be expert at image processing of electron micrographs, and have a little knowledge of computer science, as well. However, all the persons who require Eos does not an expert for CUI. Thus we extended Eos to a web system independent of OS with graphical user interfaces (GUI) by integrating web browser.Advantage to use web browser is not only to extend Eos with GUI, but also extend Eos to work under distributed computational environment. Using Ajax (Asynchronous JavaScript and XML) technology, we implemented more comfortable user-interface on web browser. Eos has more than 400 commands related to image processing for electron microscopy, and the usage of each command is different from each other. Since the beginning of development, Eos has managed their user-interface by using the interface definition file of "OptionControlFile" written in CSV (Comma-Separated Value) format, i.e., Each command has "OptionControlFile", which notes information for interface and its usage generation. Developed GUI system called "Zephyr" (Zone for Easy Processing of HYpermedia Resources) also accessed "OptionControlFIle" and produced a web user-interface automatically, because its mechanism is mature and convenient,The basic actions of client side system was implemented properly and can supply auto-generation of web-form, which has functions of execution, image preview, file-uploading to a web server. Thus the system can execute Eos commands with unique options for each commands, and process image analysis. There remain problems of image file format for visualization and workspace for analysis: The image file format information is useful to check whether the input/output file is correct and we also

    We present a newly developed software framework, MMA-EoS, that evaluates phase equilibria and thermodynamic properties of multicomponent systems by Gibbs energy minimization, with application to mantle petrology. The code is versatile in terms of the equation-of-state and mixing properties and allows for the computation of properties of single phases, solution phases, and multiphase aggregates. Currently, the open program distribution contains equation-of-state formulations widely used, that is, Caloric-Murnaghan, Caloric-Modified-Tait, and Birch-Murnaghan-Mie-Grüneisen-Debye models, with published databases included. Through its modular design and easily scripted database, MMA-EoS can readily be extended with new formulations of equations-of-state and changes or extensions to thermodynamic data sets. We demonstrate the application of the program by reproducing and comparing physical properties of mantle phases and assemblages with previously published work and experimental data, successively increasing complexity, up to computing phase equilibria of six-component compositions. Chemically complex systems allow us to trace the budget of minor chemical components in order to explore whether they lead to the formation of new phases or extend stability fields of existing ones. Self-consistently computed thermophysical properties for a homogeneous mantle and a mechanical mixture of slab lithologies show no discernible differences that require a heterogeneous mantle structure as has been suggested previously. Such examples illustrate how thermodynamics of mantle mineralogy can advance the study of Earth's interior.

    Full Text Available Abstract To appreciate the influence of the introduction of the Eastern cottontail (<em>Sylvilagus floridanusem> on the food habits of the red fox (Vulpes vulpes, between June 1998 and February 2000 fox diet was investigated by means of scat analysis (N=115 in a 250 ha wide Natural Reserve of NW Italy, and compared with data collected in the same area prior to cottontail colonization (1988-1989. Comparison included also the diet of badgers (<em>Meles melesem>, considered as potential competitors for food resources. Alien lagomorphs (mean percent volume, Vm% = 68% represented by far the most exploited resource, only three other food items reaching values of mean percent volume barely higher than 5%. Cottontails frequency of occurrence did not vary according either to season or to their reproductive cycle (II-IX vs. X-I, whilst diet niche breadth varied inversely proportional to the use of this key-resource. Overall fox trophic niche breadth varied from 0.64 in 1988-89 to 0.31 in 1998-00 (B, Levin’s index. These findings led us to consider the feeding habits of the fox in the study area as a result of local specialization of a typical generalist carnivore, according to the predictions of optimal foraging theory. No variation occurred in the badger niche breadth since cottontail introduction, whilst niche overlap between foxes and badgers decreased from 0.59 to 0.13 (O, Pianka’s index, possibly reducing competition for food in summer.

    A locus at 19p13 is associated with breast cancer (BC) and ovarian cancer (OC) risk. Here we analyse 438 SNPs in this region in 46,451 BC and 15,438 OC cases, 15,252 BRCA1 mutation carriers and 73,444 controls and identify 13 candidate causal SNPs associated with serous OC (P=9.2 × 10−20), ER-negative BC (P=1.1 × 10−13), BRCA1-associated BC (P=7.7 × 10−16) and triple negative BC (P-diff=2 × 10−5). Genotype-gene expression associations are identified for candidate target genes ANKLE1 (P=2 × 10−3) and ABHD8 (P<2 × 10−3). Chromosome conformation capture identifies interactions between four candidate SNPs and ABHD8, and luciferase assays indicate six risk alleles increased transactivation of the ADHD8 promoter. Targeted deletion of a region containing risk SNP rs56069439 in a putative enhancer induces ANKLE1 downregulation; and mRNA stability assays indicate functional effects for an ANKLE1 3′-UTR SNP. Altogether, these data suggest that multiple SNPs at 19p13 regulate ABHD8 and perhaps ANKLE1 expression, and indicate common mechanisms underlying breast and ovarian cancer risk. PMID:27601076
