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

    2003-08-01

    Desde a descoberta dos gradientes de abundância química em galáxias espirais, as regiões HII galáticas têm sido intensamente estudadas com o objetivo de determinar a forma do gradiente de abundância química na Via-Láctea. Entretanto, a forma do gradiente galático continua controversa e existem muitas regiões HII que continuam inexploradas. A região HII galática NGC 2579 é um objeto que aparece em imagens Ha, como uma pequena mancha brilhante de aproximadamente 2 segundos de arco de diâmetro a 20 segundos de arco ao leste de RCW 20, sendo NGC 2579 muitas vezes confundida com esta última. Apesar de seu alto brilho superficial, NGC 2579 é um objeto pouco estudado provavelmente por problemas de identificação deste objeto. Como parte de um projeto de reavaliação dos gradientes de abundância química das regiões HII na Via-Láctea, estamos realizando um estudo extensivo das propriedades físicas básicas como temperatura eletrônica, densidade eletrônica e composição química da região HII galática NGC 2579. Analisamos dados espectrofotométricos de fenda longa na faixa de 3700Å a 7750Å obtidos com o telescópio de 1.52 m do ESO, Chile, em 2002. Determinamos a temperatura eletrônica usando a razão entre as linhas do [OIII] (l4959+l5007/l4363) e a densidade eletrônica pela razão entre as linhas do [SII] (l6716/l6731). As abundâncias químicas do O, N, Cl, S, Ne e He foram determinadas. Realizamos um estudo de imagens fotométricas nas bandas UBVRI obtidas em 2000 no observatório astronômico San Pedro Mártir, México, para identificar e classificar as estrelas ionizantes de NGC 2579 e determinar a distância deste objeto.

    O código KOREL é uma ferramenta adicional eficiente para a determinação simultânea de parâmetros orbitais espectroscópicos para o desembaraço de espectros individuais de sistemas estelares com até cinco componentes. Estudos já realizados (Torres,KBV,2002, Dissertação de Mestrado DF-ICEx-UFMG) mostram as limitações, aplicabilidade e eficiência do código para sistemas com duas componentes. Apresentamos, neste trabalho, a continuação dos estudos para sistemas com três componentes (sistemas hierárquicos), utilizando espectros sintéticos "gabaritos" de estrelas individuais em órbitas cujos parâmetros são conhecidos "a priori". Geramos os espectros compostos e verificamos como o código reproduz os parâmetros orbitais e espectros individuais em diversas situações físicas. É apresentado, ainda, uma discussão da aplicabilidade do código em sistemas reais como RV Crateris (Machado,ACM,1997, Dissertação de Mestrado DF-ICEx-UFMG), um sistema triplo cujas componentes eclipsantes estão, provavelmente, ainda na fase pré-sequência principal.

    Fission isomers in 236U and 238U have been populated in 235U(d, p)236Um, 236U(d, pn)236Um, and the 238U(d, pn)238Um reactions. Time spectra of fission fragments with respect to the cyclotron beam pulses have been measured. From these measurements the isomeric-to-prompt fission ratios are derived for deuteron energies ranging from 17 to 25 MeV. The isomeric-to-prompt ratios show a distinct maximum around 20 MeV for the (d, pn) reactions, whereas a monotonic decrease is observed for the 235U(d, p)236Um reaction. NUCLEAR REACTIONS, FISSION 235U(d, pf) and 236,238U(d, pnf), measured delayed fission fragment time spectra, deduced isomeric-to-prompt fission ratios.

    Here, we present 6-9 um spectra of a sample of RNe, HII regions, YSOs, evolved stars and galaxies that show strong unidentified infrared bands, obtained with the ISO-SWS. The IR emission features show pronounced variations. 1) The 6.2 um feature shifts and clearly shows profile variations. 2) The 7.7 um complex is comprised of at least two subpeaks peaking at 7.6 and one longwards of 7.7 um. In some cases the main peak can apparently shift up to 8 um. Two sources do not exhibit a 7.7 um complex but instead show a broad emission feature at 8.22 um. 3) The 8.6 um feature has a symmetric profile in all sources and some sources exhibit this band at slightly longer wavelengths. For the 6.2, 7.7 and 8.6 um features, the sources have been classified independently based on their profile and peak position. The classes derived for these features are directly linked with each other. Furthermore, the observed 6--9 um spectrum depends on the type of object. We attribute the observed 6.2 um profile and peak position to the combined effect of a PAH family and anharmonicity with pure PAHs representing the 6.3 um component and substituted/complexed PAHs representing the 6.2 um component. The 7.6 um component is well reproduced by both pure and substituted/complexed PAHs but the 7.8 um component remains an enigma. In addition, the exact identification of the 8.22 um feature remains unknown. The observed variations in the characteristics of the IR emission bands are linked to the local physical conditions. Possible formation and evolution processes that may influence the interstellar PAH class are highlighted.

    2003-08-01

    Wavelets e outras formas de análise multiescalar têm sido amplamente empregadas em diversas áreas do conhecimento, sendo reconhecidamente superiores a técnicas mais tradicionais, como as análises de Fourier e de Gabor, em certas aplicações. Embora a teoria dos wavelets tenha começado a ser elaborada há quase trinta anos, seu impacto no estudo de imagens astronômicas tem sido pequeno até bem recentemente. Apresentamos um conjunto de programas desenvolvidos ao longo dos últimos três anos no Observatório do Valongo/UFRJ que possibilitam aplicar essa poderosa ferramenta a problemas comuns em astronomia, como a remoção de ruído, a detecção hierárquica de fontes e a modelagem de objetos com perfis de brilho arbitrários em condições não ideais. Este pacote, desenvolvido para execução em plataforma IDL, teve sua primeira versão concluída recentemente e está sendo disponibilizado à comunidade científica de forma aberta. Mostramos também resultados de testes controlados ao quais submetemos os programas, com a sua aplicação a imagens artificiais, com resultados satisfatórios. Algumas aplicações astrofísicas foram estudadas com o uso do pacote, em caráter experimental, incluindo a análise da componente de luz difusa em grupos compactos de galáxias de Hickson e o estudo de subestruturas de nebulosas planetárias no espaço multiescalar.

  12. Uh and um revisited: are they interjections for signaling delay?

    PubMed

    O'Connell, Daniel C; Kowal, Sabine

    2005-11-01

    Clark and Fox Tree (2002) have presented empirical evidence, based primarily on the London-Lund corpus (LL; Svartvik & Quirk, 1980), that the fillers uh and um are conventional English words that signal a speaker's intention to initiate a minor and a major delay, respectively. We present here empirical analyses of uh and um and of silent pauses (delays) immediately following them in six media interviews of Hillary Clinton. Our evidence indicates that uh and um cannot serve as signals of upcoming delay, let alone signal it differentially: In most cases, both uh and um were not followed by a silent pause, that is, there was no delay at all; the silent pauses that did occur after um were too short to be counted as major delays; finally, the distributions of durations of silent pauses after uh and um were almost entirely overlapping and could therefore not have served as reliable predictors for a listener. The discrepancies between Clark and Fox Tree's findings and ours are largely a consequence of the fact that their LL analyses reflect the perceptions of professional coders, whereas our data were analyzed by means of acoustic measurements with the PRAAT software (www.praat.org). A comparison of our findings with those of O'Connell, Kowal, and Ageneau (2005) did not corroborate the hypothesis of Clark and Fox Tree that uh and um are interjections: Fillers occurred typically in initial, interjections in medial positions; fillers did not constitute an integral turn by themselves, whereas interjections did; fillers never initiated cited speech, whereas interjections did; and fillers did not signal emotion, whereas interjections did. Clark and Fox Tree's analyses were embedded within a theory of ideal delivery that we find inappropriate for the explication of these phenomena. PMID:16341914

  14. QuorUM: An Error Corrector for Illumina Reads

    PubMed Central

    Marçais, Guillaume; Yorke, James A.; Zimin, Aleksey

    2015-01-01

    Motivation Illumina Sequencing data can provide high coverage of a genome by relatively short (most often 100 bp to 150 bp) reads at a low cost. Even with low (advertised 1%) error rate, 100 × coverage Illumina data on average has an error in some read at every base in the genome. These errors make handling the data more complicated because they result in a large number of low-count erroneous k-mers in the reads. However, there is enough information in the reads to correct most of the sequencing errors, thus making subsequent use of the data (e.g. for mapping or assembly) easier. Here we use the term “error correction” to denote the reduction in errors due to both changes in individual bases and trimming of unusable sequence. We developed an error correction software called QuorUM. QuorUM is mainly aimed at error correcting Illumina reads for subsequent assembly. It is designed around the novel idea of minimizing the number of distinct erroneous k-mers in the output reads and preserving the most true k-mers, and we introduce a composite statistic ? that measures how successful we are at achieving this dual goal. We evaluate the performance of QuorUM by correcting actual Illumina reads from genomes for which a reference assembly is available. Results We produce trimmed and error-corrected reads that result in assemblies with longer contigs and fewer errors. We compared QuorUM against several published error correctors and found that it is the best performer in most metrics we use. QuorUM is efficiently implemented making use of current multi-core computing architectures and it is suitable for large data sets (1 billion bases checked and corrected per day per core). We also demonstrate that a third-party assembler (SOAPdenovo) benefits significantly from using QuorUM error-corrected reads. QuorUM error corrected reads result in a factor of 1.1 to 4 improvement in N50 contig size compared to using the original reads with SOAPdenovo for the data sets investigated. Availability QuorUM is distributed as an independent software package and as a module of the MaSuRCA assembly software.

    2013-05-06

    The technical paper summarizes the project work conducted in the development of Kerf-Free silicon wafering equipment for silicon solar wafering. This new PolyMax technology uses a two step process of implantation and cleaving to exfoliate 50um to 120um wafers with thicknesses ranging from 50um to 120um from a 125mm or 156mm pseudo-squared silicon ingot. No kerf is generated using this method of wafering. This method of wafering contrasts with the current method of making silicon solar wafers using the industry standard wire saw equipment. The report summarizes the activity conducted by Silicon Genesis Corporation in working to develop this technology further and to define the roadmap specifications for the first commercial proto-type equipment for high volume solar wafer manufacturing using the PolyMax technology.

    We present J-band long-slit spectroscopic observation of NGC 1068 classified as a Seyfert 2 galaxy. J-band observations with OAO/ISLE provide clear detection of spatially extended [Fe II]1.257um and [P II]1.188um lines. We found that [Fe II]1.257um/[P II]1.188um increases with distance from a central continuum peak. Observed line ratios around the nucleus (continuum peak) are consistent with a typical value expected from photoionization models, while the ratios at 3" - 4" (210-280 pc) east and west of the nucleus are slightly higher than this. In the off nucleus region of NGC 1068 we also found a possible association between [Fe II]1.257um/[P II]1.188um and the radio continuum. This suggests a mild contribution of shock ionization induced by a radio jet outside nucleus while photoionization by the central energy source is dominant near the nucleus.

  18. OT2_trawle_3: 70um photometry to constrain unusually warm dust in cluster galaxies

    NASA Astrophysics Data System (ADS)

    Rawle, T.

    2011-09-01

    Complete 6 band (70-500um) observations of spectroscopically-confirmed cluster members in the Bullet Cluster have revealed a galaxy population with unexpectedly warm dust (T>40K) for sub-LIRG sources. No field sources of similar luminosity, at any redshift, have comparable dust temperatures, indicating that such warm dust may at least be preferentially located in dense environments. There are currently two problems testing this hypothesis more rigorously: (1) constraining the temperature of warm dust at z~0.3, requires 70um data, as the peak moves blue-ward of the range adequately constrained by 100 and 160um alone; (2) 70um observations of massive clusters are rare, as Spitzer/MIPS was only sensitive enough to probe the nearest poor cluster environments, and Herschel programs have tended to opt for only the 100um filter configuration. Indeed, the Bullet Cluster remains one of the only massive clusters with deep 6-band Herschel photometry. Here we propose deep 70um PACS observations of four clusters from the Herschel Lensing Survey (HLS): A68, A2744, AS1063, A851 (26.1 hours in total). This sample has the advantage of existing deep 5-band Herschel data, as well 5-band Spitzer IRAC/MIPS coverage and a wealth of optical ancillary data, including 1000s of spectroscopic redshifts. The systems cover a range of cluster morphologies (multi-component mergers to relaxed systems). The observations will allow us to: (1) constrain the characteristic dust temperature of cluster galaxies with unusually warm dust; (2) search for similarly warm dust in foreground field galaxies to assess whether the phenomenon is a product of environment; (3) better constrain the FIR luminosity for all Herschel sources, using 70um to sample the mid-IR gap between 24 and 100um, and the deeper 160um data to increase the number of SPIRE sources detected by PACS; (4) improve Herschel-based photometric redshifts for high-z lensed sources.

    Back Side Illumination (BSI) CMOS image sensors with two-layer photo detectors (2LPDs) have been fabricated and evaluated. The test pixel array has green pixels (2.2um x 2.2um) and a magenta pixel (2.2um x 4.4um). The green pixel has a single-layer photo detector (1LPD). The magenta pixel has a 2LPD and a vertical charge transfer (VCT) path to contact a back side photo detector. The 2LPD and the VCT were implemented by high-energy ion implantation from the circuit side. Measured spectral response curves from the 2LPDs fitted well with those estimated based on light-absorption theory for Silicon detectors. Our measurement results show that the keys to realize the 2LPD in BSI are; (1) the reduction of crosstalk to the VCT from adjacent pixels and (2) controlling the backside photo detector thickness variance to reduce color signal variations.

    Using VLT/FLAMES optical IFU observations, we present a detailed study of UM 448, a nearby Blue Compact Galaxy (BCG) previously reported to have an anomalously high N/O abundance ratio. NTT/SuSI2 images reveal a morphology suggestive of a merger of two systems of contrasting colour, whilst our H-alpha emission maps resolve UM 448 into three separate regions that do not coincide with the stellar continuum peaks. UM 448 exhibits complex emission line profiles, with lines consisting of a narrow, central component, an underlying broad component and a third, narrow blue-shifted component. Radial velocity maps show signs of solid body rotation across UM 448, with a projected rotation axis that correlates with the continuum morphology of the galaxy. A spatially-resolved, chemodynamical analysis is presented. Whilst the eastern tail of UM 448 has electron temperatures (Te) that are typical of BCGs, we find a region within the main body of the galaxy where the narrow and broad [O III] 4363 line components trace temper...

    We present mid-infrared spectroscopy obtained with the Spitzer Space Telescope of a sample of 11 optically faint, infrared luminous galaxies selected from a Spitzer MIPS 70um imaging survey of the NDWFS Bootes field. These are the first Spitzer IRS spectra presented of distant 70um-selected sources. All the galaxies lie at redshifts 0.3infrared luminosities of L_IR~ 0.1-17 x 10^12 solar luminosities. Seven of the galaxies exhibit strong emission features attributed to polycyclic aromatic hydrocarbons (PAHs). The average IRS spectrum of these sources is characteristic of classical starburst galaxies, but with much larger infrared luminosities. The PAH luminosities of L(7.7) ~ 0.4 - 7 x 10^11 solar luminosities imply star formation rates of ~ 40 - 720 solar masses per year. Four of the galaxies show deep 9.7um silicate absorption features and no significant PAH emission features (6.2um equivalent widths infrared luminosities and low f70/f24 flux density ratios suggests that these sources have AGN as the dominant origin of their large mid-infrared luminosities, although deeply embedded but luminous starbursts cannot be ruled out. If the absorbed sources are AGN-dominated, a significant fraction of all far-infrared bright, optically faint sources may be dominated by AGN.

  10. Lens or Binary? Chandra Observations of the Wide Separation Broad Absorption Line Quasar Pair UM425

    E-print Network

    T. L. Aldcroft; P. J. Green

    2003-04-22

    We have obtained a 110 ksec Chandra ACIS-S exposure of UM425, a pair of QSOs at z=1.47 separated by 6.5 arcsec, which show remarkably similar emission and broad absorption line (BAL) profiles in the optical/UV. Our 5000 count X-ray spectrum of UM425A (the brighter component) is well-fit with a power law (photon spectral index Gamma=2.0) partially covered by a hydrogen column of 3.8x10^22 cm^-2. The underlying power-law slope for this object and for other recent samples of BALQSOs is typical of radio-quiet quasars, lending credence to the hypothesis that BALs exist in every quasar. Assuming the same Gamma for the much fainter image of UM425B, we detect an obscuring column 5 times larger. We search for evidence of an appropriately large lensing mass in our Chandra image and find weak diffuse emission near the quasar pair, with an X-ray flux typical of a group of galaxies at redshift z ~ 0.6. From our analysis of archival HST WFPC2 and NICMOS images, we find no evidence for a luminous lensing galaxy, but note a 3-sigma excess of galaxies in the UM425 field with plausible magnitudes for a z=0.6 galaxy group. However, the associated X-ray emission does not imply sufficient mass to produce the observed image splitting. The lens scenario thus requires a dark (high M/L ratio) lens, or a fortuitous configuration of masses along the line of sight. UM425 may instead be a close binary pair of BALQSOs, which would boost arguments that interactions and mergers increase nuclear activity and outflows.

    2005-08-01

    Cada vez mais a humanidade, em sua imensa maioria, está alheia às próprias conquistas. A insatisfação com esta realidade tem levado muitos pesquisadores, instituições, empresas e governos a procurar formas alternativas de acompanhar e transmitir todo este acervo científico cultural à sociedade, buscando a melhoria da qualidade da divulgação científica e contribuindo para o processo de cultura e alfabetização científica. Não há tempo nem espaço nos limitados planos curriculares do ensino médio e mesmo nos programas de ensino que propiciem a cultura científica e o acompanhamento do vertiginoso progresso científico e tecnológico atual. Neste sentido, a educação formal escolar precisa ser complementada ou acrescida de uma educação informal, extra-escolar, que possa oferecer à sociedade o que a escola não pode oferecer. A interação do público com museus, feiras de ciências, planetários, exposições científicas e/ou culturais é de grande importância para a aquisição e difusão de conhecimentos relacionados ao mundo científico. Reconhecidamente como um modelo de alfabetização científica esses ambientes promovem uma interação social capaz de propiciar de forma efetiva uma melhor relação ensino-aprendizagem com o público. Partindo desta realidade a Universidade Cruzeiro do Sul e a Escola Municipal de Astronomia (EMA) vêm desenvolvendo um projeto de intervenção no espaço em torno do Planetário do Parque do Ibirapuera com o objetivo de se implantar um ambiente de aprendizagem motivador e desafiador que promova a popularização de conteúdos relacionados à astronomia, astrofísica e cosmologia. Busca-se, também, a aproximação e interação do público com exposições que estão sendo implementadas no planetário. Considerando que se trata de um projeto de mestrado em fase inicial o objetivo do presente trabalho é apresentar a concepção básica e os critérios que estão sendo utilizados do ponto de vista pedagógico para as indicações dos objetos e experimentos que serão expostos, procurando formas de construir, expor e apresen! tá-los d e maneira mais eficiente em termos de uma aprendizagem significativa.

  16. Um enfoque antropológico para o ensino de astronomia no nível médio

    NASA Astrophysics Data System (ADS)

    Costa, G. B.; Jafelice, L. C.

    2003-08-01

    Há uma enorme carência de materiais didático-pedagógicos em astronomia para professores do ensino médio, sobretudo materiais que explorem também aspectos humanísticos. A origem do Universo é um bom exemplo desta constatação central. Embora tal origem teve explicações culturais diversas, os professores não têm informações sobre isso e muito menos material que trabalhe diferentes visões de mundo e treinamento que os capacite a abordá-las devidamente. Conseqüentemente o ensino de astronomia costuma ser tecnicista e dissociado do aspecto humano que alimenta o grande interesse e curiosidade que esses temas despertam. Aqui apresentamos propostas visando contribuir para reverter esse quadro e trabalhamos distintas visões de Universo: espontâneas, autóctones e científicas. Desenvolvemos práticas, materiais instrucionais e textos para viabilizar a adoção de um enfoque antropológico para o ensino de astronomia no nível médio, no qual as culturas humanística e científica sejam integradas de uma maneira contextualizada e eficaz para aquele ensino. Estas propostas foram aplicadas em um curso de treinamento para professores da rede pública de diferentes disciplinas. A receptividade dos professores à abordagem proposta e os resultados alcançados foram muito estimulantes. Destes, destacamos: produção de roteiros de atividades; desenvolvimento de práticas didático-pedagógicas específicas (e.g., encenação de mitos; dança primordial guarani; "criação" de constelações e interpretações pluriculturais; etc.); e sugestões concretas para a efetiva realização de um ensino interdisciplinar contextualizado, onde questões cosmogônicas servem de mote para iniciar tal ensino. Discutimos estes resultados e como o enfoque adotado pode instrumentalizar os professores para leituras de mundo que incluem naturalmente aspectos culturais, sociais e históricos associados aos temas estudados.

    We take advantage of good atmospheric transparency and the availability of high quality instrumentation in the 1 um near-infrared atmospheric window to present a grid of F, G, K, and M spectral standards observed at high spectral resolution (R ~ 25,000). In addition to a spectral atlas, we present a catalog of atomic line absorption features in the 0.95-1.11 um range. The catalog includes a wide range of line excitation potentials, from 0-13 eV, arising from neutral and singly ionized species, most frequently those of Fe I and Ti I at low excitation, Cr I, Fe I, and Si I at moderate excitation, and C I, S I, and Si I having relatively high excitation. The spectra also include several prominent molecular bands from CN and FeH. For the atomic species, we analyze trends in the excitation potential, line depth, and equivalent width across the grid of spectroscopic standards to identify temperature and surface gravity diagnostics near 1 um. We identify the line ratios that appear especially useful for spectral typ...

    2014-06-01

    Since its construction in 2007, the UM-Dearborn Observatory has provided a valuable educational tool both for students at UM-Dearborn and our neighbor-institution the Henry Ford Community College, and for the public at-large. We have recently (Jan 2014) added a systematic long-term research program with our 0.4m main telescope, to photometrically monitor a number of bright variable objects, including X-ray binaries and chemically-peculiar metal-poor stars over long timescales. We ultimately envision assembling a photometric database of (at least) four-color photometry over years-decades (i.e., many hundreds of orbital timescales for close binaries), with the preponderance of datapoints taken by undergraduates. To conduct this program, we have had to overcome a number of site challenges, the solutions of which will be useful to many programs using small telescopes at urban sites. The 0.4m telescope lies on a shared building within UM-Dearborn's main Fairlane campus - i.e., is about 20 meters above sea level, near several sources of water vapor (including an active steam vent less than 15 meters away), experiences significant mechanical vibrations from other building functions, and lies about 6 miles from central Detroit, well within the Detroit-Ann Arbor conurbation. Observing conditions are thus highly variable, with 5 arcsecond seeing typical and significant transparency variations observed even during a clear night. Nevertheless, we are now able to make scientifically useful observations in a semi-automatic way, to which our chosen scientific niche is well-suited. We present here our solutions to these challenges, along with initial results from our ongoing monitoring program.

  7. Comparing the genomes of Helicobacter pylori clinical strain UM032 and Mice-adapted derivatives

    PubMed Central

    2013-01-01

    Background Helicobacter pylori is a Gram-negative bacterium that persistently infects the human stomach inducing chronic inflammation. The exact mechanisms of pathogenesis are still not completely understood. Although not a natural host for H. pylori, mouse infection models play an important role in establishing the immunology and pathogenicity of H. pylori. In this study, for the first time, the genome sequences of clinical H. pylori strain UM032 and mice-adapted derivatives, 298 and 299, were sequenced using the PacBio Single Molecule, Real-Time (SMRT) technology. Result Here, we described the single contig which was achieved for UM032 (1,599,441 bp), 298 (1,604,216 bp) and 299 (1,601,149 bp). Preliminary analysis suggested that methylation of H. pylori genome through its restriction modification system may be determinative of its host specificity and adaptation. Conclusion Availability of these genomic sequences will aid in enhancing our current level of understanding the host specificity of H. pylori. PMID:23957912

    Many nuclear utility companies have now performed plant-specific system reliability assessments (SRAs) for a variety of applications, such as determination of alternative system design modifications, assessment of testing and maintenance strategies, examination of procedural changes, responding to regulatory inquiries, etc. Manually updating the SRA logic models and component reliability data to keep them up-to-date is a tedious, time-consuming, man-power-intensive, and sometimes impractical task. The amount of information as well as the lack of adequate computer software for automated updating makes it difficult to keep the SRAs current. RAPID's RAM and UM software, which are part of the Electric Power Research Institute (EPRI's) RAPID software development effort under the risk assessment program of the Nuclear Power Division, are designed to overcome many of these difficulties and to provide a productive environment for performing various system reliability engineering activities. This paper summarizes the development and demonstration of the RAPID/RAM-UM software at Arizona Nuclear Power Project (ANPP's) Palo Verde Nuclear Generation Station.

    We discuss the nature of faint 6.7um galaxies detected with the mid-infrared camera ISOCAM on board the Infrared Space Observatory (ISO). The 23 hour integration on the Hawaii Deep Field SSA13 has provided a sample of 65 sources down to 6uJy at 6.7um. For 57 sources, optical or near-infrared counterparts were found with a statistical method. All four Chandra sources, three SCUBA sources, and one VLA/FIRST source in this field were detected at 6.7um with high significance. Using their optical to mid-infrared colors, we divided the 6.7um sample into three categories: low redshift galaxies with past histories of rapid star formation, high redshift ancestors of these, and other star forming galaxies. Rapidly star forming systems at high redshifts dominate the faintest end. Spectroscopically calibrated photometric redshifts were derived from fits to a limited set of template SEDs. They show a high redshift tail in their distribution with faint (1. The 6.7um galaxies tend to have brighter K magnitudes and redder I-K colors than the blue dwarf population at intermediate redshifts. Stellar masses of the 6.7um galaxies were estimated from their rest-frame near-infrared luminosities. Massive galaxies (M_star~10e11M_sun) were found in the redshift range of z=0.2-3. Epoch dependent stellar mass functions indicate a decline of massive galaxies' comoving space densities with redshift. Even with such a decrease, the contributions of the 6.7um galaxies to the stellar mass density in the universe are found to be comparable to those expected from UV bright galaxies detected in deep optical surveys.

Nine galaxies (four in Abell 2218 and five in Abell 2219) were detected with flux levels in the range 530-1100 microJy. Three of the galaxies detected in Abell 2218 have previously known redshifts; of these one is a foreground galaxy and the other two are lensed background galaxies at z=0.474 and z=1.032. One of the objects detected in the field of Abell 2219 is a faint, optically red, extreme infrared-dominated galaxy with a probable redshift of 1.048.

    We demonstrate that both the current (New Dynamics), and next generation (ENDGame) dynamical cores of the UK Met Office global circulation model, the UM, reproduce consistently, the long-term, large-scale flows found in several published idealised tests. The cases presented are the Held-Suarez test, a simplified model of Earth (including a stratosphere), and a hypothetical tidally locked Earth. Furthermore, we show that using simplifications to the dynamical equations, which are expected to be justified for the physical domains and flow regimes we have studied, and which are supported by the ENDGame dynamical core, also produces matching long-term, large-scale flows. Finally, we present evidence for differences in the detail of the planetary flows and circulations resulting from improvements in the ENDGame formulation over New Dynamics.

    O ângulo sólido subtendido pelos pixels na câmara infravermelha do NexGal (CamIV) que operamos no OPD/LNA contém contribuições provenientes do sistema de coleta de fluxo propriamente dito - sendo esta a parte que interessa para as medidas astronômicas - e contribuições da obstrução central, sistema de suporte do espelho secundário e região exterior à pupila de entrada do telescópio. Estas últimas contribuições são devi-das à emissão de corpo negro à temperatura ambiente e aumentam exponencialmente para comprimentos de onda maiores que 2 micra (banda K, no infravermelho próximo). Embora a resultante pode ser quantificada e subtraída dos sinais relevantes, sua variância se adiciona à variância do sinal, e pode ser facilmente a contribuição domi-nante para a incerteza final das medidas, tornando ineficiente o processo de extração de informação e degradando a sensibilidade da câmara. A maneira clássica de resolver esse problema em sistemas ópticos que operam no infravermelho, onde os efeitos da emissão térmica do ambiente são importantes, é restringir o ângulo sólido subtendido pelos pixels individuais exclusivamente aos raios provenientes do sistema óptico. Para tanto, projeta-se uma imagem real, bastante reduzida, da pupila de entrada do sistema óptico num anteparo que transmita para o sistema de imageamento só o que interessa, bloqueando as contribuições das bordas externas à pupila de entrada, obstrução central do telescópio e sistema de suporte. Como a projeção é realizada em ambiente criogênico, a contribuição térmica espúria é efetivamente eliminada. Nós optamos por um sistema do tipo Offner para implementar na prática esta função. Trata-se de um sistema baseado em espelhos esféricos, bastante compacto e ajustado por construção. A opção por espelhos do mesmo material que o sistema de suporte (Alumínio) minimiza a dilatação diferencial, crítica nesse tipo de aplicação. Apresentamos as soluções detalhadas do projeto óptico-mecânico, bem como uma análise de flexões e desempenho em termos de qualidade de imagem.

    Although T Tauri is one of the most studied young objects in astronomy, the nature of its circumstellar environment remains elusive due, in part, to the small angular separation of its three components (North-South and South a-b are separated by 0.68" and 0.12" respectively). Taking advantage of incredibly stable, high Strehl, PSFs obtained with Mid-IR adaptive optics at the 6.5 meter MMT, we are able to resolve the system on and off the 10um silicate dust feature (8.7um, 10.55um, and 11.86um; 10% bandwidth), and broad N. At these wavelengths, South a-b are separated by only ~0.3 lambda/D. This paper describes a robust Markov Chain Monte Carlo technique to separate all three components astrometrically and photometrically, for the first time, in the mid-IR. Our results show that the silicate feature previously observed in the unresolved T Tau South binary is dominated by T Tau Sa's absorption, while Sb does not appear to have a significant feature. This suggests that a large circumbinary disk around Sa-Sb is not likely the primary source of cool dust in our line-of-sight, and that T Tau Sa is enshrouded by a nearly edge-on circumstellar disk. Surprisingly, T Tau Sb does not appear to have a similarly oriented disk.

    We have obtained a 110 ks Chandra ACIS-S exposure of UM 425, a pair of QSOs at z=1.47 separated by 6.5", which show remarkably similar emission and broad absorption line (BAL) profiles in the optical/UV. Our 5000 count X-ray spectrum of UM 425A (the brighter component) is well fitted with a power law (photon spectral index ?=2.0) partially covered by a hydrogen column of 3.8×1022 cm-2. The underlying power-law slope for this object and for other recent samples of BALQSOs is typical of radio-quiet quasars, lending credence to the hypothesis that BALs exist in every quasar. Assuming the same ? for the much fainter image of UM 425B, we detect an obscuring column 5 times larger. We search for evidence of an appropriately large lensing mass in our Chandra image and find weak diffuse emission near the quasar pair, with an X-ray flux typical of a group of galaxies at redshift z~0.6. From our analysis of archival HST WFPC2 and NICMOS images, we find no evidence for a luminous lensing galaxy, but note a 3 ? excess of galaxies in the UM 425 field with plausible magnitudes for a z=0.6 galaxy group. However, the associated X-ray emission does not imply sufficient mass to produce the observed image splitting. The lens scenario thus requires a dark (high M/L ratio) lens or a fortuitous configuration of masses along the line of sight. UM 425 may instead be a close binary pair of BALQSOs, which would boost arguments that interactions and mergers increase nuclear activity and outflows.

  5. Diagnosing resolution sensitivity over the Maritime Continent in the MetUM

    The Maritime Continent, with over 25,000 islands ranging from hundreds to 780,000 square kilometers, is a key challenge for cumulus-convection and coastal parameterizations in climate resolution GCMs. We studied the resolution sensitivity of precipitation over the Maritime Continent in the MetUM AGCM at horizontal resolutions ranging from approximately 200 to 40 km. We found robust increases in summer precipitation over the Maritime Continent Islands and decreases in summer precipitation over the northern Maritime Continent seas, similar to the resolution sensitivity seen in other studies. These precipitation changes near the Maritime Continent can be large, exceeding 5 mm/day, and are the largest changes in tropical precipitation as resolution is increased. To explore the source of these changes, we present novel experiments to diagnose the role of increased resolution of different components of the AGCM, such as the orography, coastlines and atmospheric dynamics, in the Maritime Continent domain. Our results suggest that total orographic precipitation in the Maritime Continent domain is resolution dependent at these scales. While increased precipitation associated with the higher resolution of the mean orography is compensated for by decreasing precipitation associated with changes in the subgrid orography and its effect on parameterized drag, the total orographic precipitation is not equal across resolutions. Experiments are in progress to determine the impact of better resolving other boundary conditions, such as coastlines.

    Land surface window emissivity is a key parameter for estimating the longwave radiative budget. The combined radiative transfer model (RM) with neural network (NN) algorithm is utilized to directly estimate the window (8-12 um) emissivity from the brightness temperature of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) with 90 m spatial resolution. Although the estimation accuracy is very high when the broadband emissivity is estimated from AST05 (ASTER Standard Data Product) by using regression method, the accuracy of AST05 is about ± 0.015 for 86 spectra which is determined by the atmosphere correction for ASTER 1B data. The MODTRAN 4 is used to simulate the process of radiance transfer, and the broadband emissivity is directly estimated from the brightness temperature of ASTER 1B data at satellite. The comparison analysis indicates that the RM-NN is more competent to estimate broadband emissivity than other method when the brightness temperatures of band 11, 12, 13, 14 are made as input nodes of dynamic neural network. The estimation average accuracy is about 0.009, and the estimation results are not sensitive to instrument noise. The RM-NN is applied to extract broadband emissivity from an image of ASTER 1B data in China, and the comparison against a classification based multiple bands with 15 m spatial resolution shows that the estimation results from RM-NN are very good.

    There is a general consensus in climate projections that the global hydrological cycle is likely to experience significant changes in the future, in response to increased concentrations of greenhouse gases. At the regional scale, model simulations show large variations in the predictions of changes in the components of the water cycle. Increasing confidence in regional prediction of the water cycle is at the top of the NWP and climate research agenda, requiring a comprehensive evaluation of the physical processes which may play an important role. Here we present preliminary results of an evaluation of the capacity of the MetUM-GC2 coupled model to reproduce the characteristics of the water cycle in the region of China. Using water budget techniques in the atmospheric and terrestrial branches we test the water cycle components and the model's ability to replicate the climatological annual cycle and its interannual variability. Recent drought and flood events are evaluated and various metrics are employed to compare the role played by the atmospheric general circulation including the boreal summer and winter monsoon regimes and soil moisture feedback in model and observations.

    We report on a search for the optical counterparts of 175 um - selected sources from the Far-Infrared Background (FIRBACK) survey in the European Large Area ISO Survey (ELAIS) N2 field. Applying a likelihood ratio technique to optical catalogues from the Isaac Newton Telescope - Wide Field Survey (INT--WFS), we found optical identifications for 33 out of 55 FIRBACK sources in this field. These were then reassessed in the light of associations with the ELAIS final catalogue for the the N2 field, to yield a final set of 31 associations. We have investigated the nature of this population through a comparison of their observed spectral energy distributions with predictions from radiative transfer models which simulate the emission from both cirrus and starburst components. We find the far-infrared sources to be 80 per cent star bursting galaxies with their starburst component at a high optical depth. The resulting SEDs were used to estimate far-infrared luminosities, star formation rates, dust temperatures and dust masses. The N2 FIRBACK population is found to consist of four suspected ULIRGs, a number of LIRGs and a population of low redshift quiescently star forming galaxies. We also discuss the implications of these results for current evolutionary models.

    2001-05-07

    A sample of 25 IR-bright planetary nebulae (PNe) towards the Galactic bulge is analysed through 8-13um spectroscopy. The classification of the warm-dust emission features provides a measure of the C/O chemical balance, and represents the first C/O estimates for bulge PNe. Out of 13 PNe with identified dust types, 4 PNe have emission features associated with C-based grains, while the remaining 9 have O-rich dust signatures. The low fraction of C-rich PNe, <30%, contrasts with that for local PNe, around 80%, although it follows the trend for a decreasing frequency of C-rich PNe with galactocentric radius (paper~I). We investigate whether the PNe discussed here are linked to the bulge stellar population (similar to type~IV, or halo, PNe) or the inner Galactic disk (a young and super-metal-rich population). Although 60% of the PNe with warm dust are convincing bulge members, none of the C-rich PNe satisfy our criteria, and they are probably linked to the inner Galactic disk. In the framework of single star evolution, the available information on bulge PNe points towards a progenitor population similar in age to that of local PNe (type I PNe are found in similar proportions), but super-metal-rich (to account for the scarcity of C-rich objects). Yet the metallicities of bulge PNe, as inferred from [O/H], fail to reach the required values - except for the C-rich objects. It is likely that the sample discussed here is derived from a mixed disk/bulge progenitor population and dominated by type IV PNe, as suggested by Peimbert (1992). The much higher fraction of O-rich PNe in this sample than in the solar neighbourhood should result in a proportionally greater injection of silicate grains into the inner Galactic medium.

    UM 625, previously identified as a narrow-line active galactic nucleus (AGN), actually exhibits broad H{alpha} and H{beta} lines whose width and luminosity indicate a low black hole (BH) mass of 1.6 Multiplication-Sign 10{sup 6} M{sub Sun }. We present a detailed multiwavelength study of the nuclear and host galaxy properties of UM 625. Analysis of Chandra and XMM-Newton observations suggests that this system contains a heavily absorbed and intrinsically X-ray weak ({alpha}{sub ox} = -1.72) nucleus. Although not strong enough to qualify as radio loud, UM 625 does belong to a minority of low-mass AGNs detected in the radio. The broadband spectral energy distribution constrains the bolometric luminosity to L{sub bol} Almost-Equal-To (0.5-3) Multiplication-Sign 10{sup 43} erg s{sup -1} and L{sub bol}/L{sub Edd} Almost-Equal-To 0.02-0.15. A comprehensive analysis of Sloan Digital Sky Survey and Hubble Space Telescope images shows that UM 625 is a nearly face-on S0 galaxy with a prominent, relatively blue pseudobulge (Sersic index n = 1.60) that accounts for {approx}60% of the total light in the R band. The extended disk is featureless, but the central {approx}150-400 pc contains a conspicuous semi-ring of bright, blue star-forming knots, whose integrated ultraviolet luminosity suggests a star formation rate of {approx}0.3 M{sub Sun} yr{sup -1}. The mass of the central BH roughly agrees with the value predicted from its bulge velocity dispersion but is significantly lower than that expected from its bulge luminosity.

    BACKGROUND Few human papillomavirus (HPV)-positive head and neck squamous cell carcinoma (HNSCC) cell lines exist. We established UM-SCC-104, a new HPV(+) HNSCC cell linefrom a recurrent oral cavity tumor, and characterized it for the presence of cancer stem cells (CSC). METHODS Tumor cells were tested for biomarker expression by immunohistology and the presence of HPV was assessed by several methods. RESULTS UM-SCC-104 has a unique genotype, contains HPV-16 and expresses E6/E7. Inoculation of (Aldehyde Dehydrogenase) ALDH(+) and ALDH(?) cells in an immunocompromised mouse resulted in tumor growth from the ALDH(+) cells after 6 weeks that recapitulated the histology of the primary, while ALDH(?) cells did not produce tumors. CONCLUSIONS UM-SCC-104, a new HPV-16, CSC-containing HNSCC cell line will aid in studying recurrent HPV(+) tumors. The aggressive nature of this tumor is consistent with high uniform expression of EGFR and a functionally significant proportion of ALDH(+) CSC. PMID:22162267

    The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the four main layers (L1–L4) in the photosynthetic mats. Chlorophyll a (Chl a) concentration and distribution (measured by HPLC and hyperspectral imaging, respectively), the phycocyanin distribution (scanned with hyperspectral imaging), oxygenic photosynthesis (determined by microsensor), and the abundance of photosynthetic microorganisms (from 16S and 18S rRNA sequencing) decreased with depth in the euphotic layer (L1). Incident irradiance exponentially attenuated in the same zone reaching 1% at 1.7-mm depth. Proteobacteria dominated all layers of the mat (24%–42% of the identified bacteria). Anoxygenic photosynthetic bacteria (dominated by Chloroflexus) were most abundant in the third red layer of the mat (L3), evidenced by the spectral signature of Bacteriochlorophyll as well as by sequencing. The deep, black layer (L4) was dominated by sulfate reducing bacteria belonging to the Deltaproteobacteria, which were responsible for high sulfate reduction rates (measured using 35S tracer). Members of Halobacteria were the dominant Archaea in all layers of the mat (92%–97%), whereas Nematodes were the main Eukaryotes (up to 87%). Primary productivity rates of Um Alhool mat were similar to those of other hypersaline microbial mats. However, sulfate reduction rates were relatively low, indicating that oxygenic respiration contributes more to organic material degradation than sulfate reduction, because of bioturbation. Although Um Alhool hypersaline mat is a nutrient-limited ecosystem, it is interestingly dynamic and phylogenetically highly diverse. All its components work in a highly efficient and synchronized way to compensate for the lack of nutrient supply provided during regular inundation periods. PMID:24658360

    We have developed a digital reflectance spectral library, with management and spectral analysis software. The library includes 498 spectra of 444 samples (some samples include a series of grain sizes) measured from approximately 0.2 to 3.0 um . The spectral resolution (Full Width Half Maximum) of the reflectance data is <= 4 nm in the visible (0.2-0.8 um) and <= 10 nm in the NIR (0.8-2.35 um). All spectra were corrected to absolute reflectance using an NIST Halon standard. Library management software lets users search on parameters (e.g. chemical formulae, chemical analyses, purity of samples, mineral groups, etc.) as well as spectral features. Minerals from borate, carbonate, chloride, element, halide, hydroxide, nitrate, oxide, phosphate, sulfate, sulfide, sulfosalt, and the silicate (cyclosilicate, inosilicate, nesosilicate, phyllosilicate, sorosilicate, and tectosilicate) classes are represented. X-Ray and chemical analyses are tabulated for many of the entries, and all samples have been evaluated for spectral purity. The library also contains end and intermediate members for the olivine, garnet, scapolite, montmorillonite, muscovite, jarosite, and alunite solid-solution series. We have included representative spectra of H2O ice, kerogen, ammonium-bearing minerals, rare-earth oxides, desert varnish coatings, kaolinite crystallinity series, kaolinite-smectite series, zeolite series, and an extensive evaporite series. Because of the importance of vegetation to climate-change studies we have include 17 spectra of tree leaves, bushes, and grasses. The library and software are available as a series of U.S.G.S. Open File reports. PC user software is available to convert the binary data to ascii files (a separate U.S.G.S. open file report). Additionally, a binary data files are on line at the U.S.G.S. in Denver for anonymous ftp to users on the Internet. The library search software enables a user to search on documentation parameters as well as spectral features. The analysis system includes general spectral analysis routines, plotting packages, radiative transfer software for computing intimate mixtures, routines to derive optical constants from reflectance spectra, tools to analyze spectral features, and the capability to access imaging spectrometer data cubes for spectral analysis. Users may build customized libraries (at specific wavelengths and spectral resolution) for their own instruments using the library software. We are currently extending spectral coverage to 150 um. The libraries (original and convolved) will be made available in the future on a CD-ROM.

    Optical fiber tapers are used to collect photoluminescence emission at ~1.5 um from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. Photoluminescence collection via fiber taper is enhanced 2.5 times relative to free space, with a total taper collection efficiency of 53%. By varying the fiber taper offset from the cavity, a broad tuning range of coupling strength is obtained. This material system combined with fiber taper collection is promising for building on-chip optical amplifiers.

    We have obtained deep Ks-band images centered on QSO UM402 (z_{em}=2.856) using IRCS camera and AO36 system at the Cassegrain focus of Subaru Telescope. A faint companion galaxy (m_{k}=21.91\\pm 0.26 in the Vega system) that lies ~2.4" north of the QSO sightline has been clearly resolved by this high resolution imaging. The non-detection of this close companion by the previous deep R-band observation indicates that it has a red color (R-K)_{Vega} >3.3. This object has irregular morphology with two close components (separation ~0.3"). Given the small impact parameter (b=19.6 kpc, at z_{lls}=2.531), it might be a candidate galaxy giving rise to the Lyman Limit system absorption at z_{abs}=2.531 seen in the QSO spectrum. Careful subtraction of the PSF from the QSO image revealed the QSO host galaxy. We modelled in detail the host galaxy properties using the 2-D decomposition algrithm GALFIT, and find that QSO UM402 is hosted by a giant elliptical of m_{k}=20.19\\pm0.15 and of a scalelength ~4 Kpc, as bright as oth...

    The Ly-alpha forest spectra obtained for the A and B images of the gravitationally lensed high-redshift quasar UM 673 are investigated, and higher resolution data of the brightest (A) image are presented. In the 2-A resolution spectra, all the absorption lines detected at 5 sigma in the spectrum of the fainter B image are present in the A image, but two anticoincidences, i.e., two lines in A which do not have a counterpart in B at more than a 3-sigma confidence level, are detected. Given the fact that corresponding Ly-alpha lines in the spectra of A and B have their equivalent widths well correlated, this proves that both light beams actually cross the same clouds. Most of the velocity differences between corresponding lines are compatible with 0 km/s within the error bars, with a standard deviation of 17 km/s. For the two major heavy-element systems detected in the spectrum of UM 673, no significant difference between the corresponding lines in the two spectra are found.

    The Um Zariq and Malhaq formations occupy roughly the northern half of the Kid metamorphic complex of SE Sinai, in the NE part of the Arabian-Nubian Shield. The Um Zariq Formation metasediments are relicts of an old sedimentary sequence (Cryogenian; 813 ± 6 Ma), whereas the Malhaq Formation records several phases of Ediacaran sedimentation and volcanic activity (615-607 Ma). The Um Zariq Formation is mainly represented by well-bedded metapelitic schists, while the Malhaq Formation comprises a series of structureless to schistose felsic to intermediate metavolcanics interbedded with mica-rich phyllites and schists. The Um Zariq metasediments are depleted in SiO2, CaO and K2O and enriched in TiO2, Al2O3 and K2O relative to those of the Malhaq Formation. Aside from the relatively low Ni and Cr concentrations, compatible transition elements of these metasediments are comparable to average crustal contents. Except for marked Sr depletion, LILEs are around average continental crust values. Pronounced negative Nb-Ta anomalies and enrichment of Um Zariq samples in Th, U, Zr, Ti and Y relative to Malhaq ones are the main features of HFSEs. The REE patterns of all samples are parallel to sub-parallel LREE-enriched, with distinct negative Eu anomalies and weakly fractionated HREE segments. The source rocks of the Malhaq Formation metasediments underwent mild to moderate chemical weathering, whereas those of the Um Zariq Formation have suffered severe chemical weathering. These metasediments are predominately derived from felsic to intermediate igneous sources, with a particular slight addition from recycled sedimentary source to the Malhaq Formation metasediments. They are collectively geochemically immature and have suffered minor sedimentary recycling, with the experience of the Malhaq Formation metasediments from higher degree of sorting and reworking. The Malhaq and Um Zariq metasediments were originally deposited in a continental arc setting, most probably back-arc basin, despite the wide time span between their individual depositions.

    Although previous studies show that robotic telescopes have the potential to enhance student learning, there is comparatively little research that focuses on teacher perceptions of this technology. This study investigates: "what is the academic merit of using SLOOH robotic telescopes to teach astronomy as perceived by science teachers?" Our sample consists of nine science teachers of students aged 13-18 years. Pre- and post-tests, interviews, and surveys were collected during two weeks of a summer online course about robotic telescopes. While pre and post-tests do not reveal a statistically significant gain in astronomy content knowledge, analysis of qualitative data reveals five themes which describe the most important aspects of using SLOOH according to participants: "Images," "Interface," "Classroom Application," "Instructor Impact," and "Logistical Issues." Analysis of these themes suggests that SLOOH can provide an interactive and social learning environment with capabilities to incorporate crossdisciplinary themes. Embora estudos anteriores mostram que os telescópios robóticos têm o potencial de melhorar a aprendizagem dos alunos, há relativamente pouca investigação focada nas percepções de professores a respeito desta tecnologia.

Nossa amostra é composta por nove professores de ciências de estudantes com idades entre 13-18 anos pré e pós-testes, entrevistas, e levantamentos foram coletados durante duas semanas de um curso on-line de verão sobre telescópios robóticos. Enquanto os testes pré e pós não revelaram um ganho estatisticamente significativo no conhecimento do conteúdo astronomia, a análise de dados qualitativos revela cinco temas que descrevem os aspectos mais importantes da utilização Slooh de acordo aos participantes: "Imagens", "Interface", "Aplicação em sala de aula", "Impacto no Instrutor" e "Questões logísticas". A análise desses temas sugere que Slooh pode proporcionar um ambiente de aprendizagem interativo e social com capacidade de incorporar temas interdisciplinares.

    With the goal to study the physical and chemical evolution of ices in solar-mass systems, a spectral survey is conducted of a sample of 41 low luminosity YSOs using 3-38 um Spitzer and ground-based spectra. The long-known 6.0 and 6.85 um bands are detected toward all sources, with the Class 0-type YSOs showing the deepest bands ever observed. In almost all sources the 6.0 um band is deeper than expected from the bending mode of pure solid H2O. The depth and shape variations of the remaining 5-7 um absorption indicate that it consists of 5 independent components, which, by comparison to laboratory studies, must be from at least 8 different carriers. Simple species are responsible for much of the absorption in the 5-7 um region, at abundances of 1-30% for CH3OH, 3-8% for NH3, 1-5% for HCOOH, ~6% for H2CO, and ~0.3% for HCOO- with respect to solid H2O. The 6.85 um band likely consists of one or two carriers, of which one is less volatile than H2O because its abundance relative to H2O is enhanced at lower H2O/tau_9.7 ratios. It does not survive in the diffuse interstellar medium (ISM), however. The similarity of the 6.85 um bands for YSOs and background stars indicates that its carrier(s) must be formed early in the molecular cloud evolution. If an NH4+ salt is the carrier its abundance with respect to solid H2O is typically 7%, and low temperature acid-base chemistry or cosmic ray induced reactions must have been involved in its formation. Possible origins are discussed for the carrier of an enigmatic, very broad absorption between 5 and 8 um. Finally, all the phenomena observed for ices toward massive YSOs are also observed toward low mass YSOs, indicating that processing of the ices by internal ultraviolet radiation fields is a minor factor in the early chemical evolution of the ices.

  11. The dependence of land-atmosphere interactions on atmospheric parametrizations in the JULES/UM modelling system

    NASA Astrophysics Data System (ADS)

    Johnson, Helen; Best, Martin

    2015-04-01

    It has been understood for a while now that atmospheric behaviour is affected by land surface processes, modelling this relationship however still presents challenges. Most numerical weather prediction (NWP) models couple an atmospheric model to a land surface model in order to forecast the weather and/or climate. The Global Land-Atmosphere Coupling Experiment (GLACE) demonstrated that soil moisture variability has considerable control over atmospheric behaviour, particularly impacting on precipitation and temperature variability. The study also suggested that differences in coupling strengths between models may be due to differences in atmospheric parametrizations. There have since been other studies which support this claim but it is not yet clear which parameters control the land-atmosphere coupling strength or indeed what it should be. In this study we investigate whether certain atmospheric parameters hold more control than others over model sensitivity to land surface changes. We focus on the interaction of the JULES (Joint UK Land Environment Simulator) land surface model with the Met Office Unified Model (UM) that is used for operational NWP and climate prediction. For computational efficiency we ran the UM at a single site using a single column model (SCM) rather than running a global model simulation. A site in the Sahel region of West Africa was chosen as this is an area that was identified by GLACE as being especially responsive to changes in soil moisture. JULES was run several times with various different initial soil moisture profiles to create an ensemble of surface sensible and latent heat fluxes that could be used to force a set of different SCM runs in order to simulate a range of different atmospheric conditions. Various atmospheric parameters in the SCM were then perturbed to create additional sets of SCM runs with different sensitivities to soil moisture changes. By analysing the difference in spread between the standard configuration and the perturbed parameter sets of SCM runs, we gain insight into which atmospheric parameters have the most control over land-atmosphere interactions. The methodology for this experiment shall be introduced and initial results presented.

  7. Geochemistry of the Neoproterozoic metasediments of Malhaq and Um Zariq formations, Kid Metamorphic Complex, Sinai, Egypt: implications for source-area weathering, provenance, recycling, and depositional tectonic setting

    The Kid Metamorphic Complex of SE Sinai represents a thick volcano-sedimentary succession that underwent polyphase deformation and greenschist to upper amphibolite facies metamorphism in the NE part of the Arabian-Nubian Shield (ANS). The Malhaq and Um Zariq Formations, the target of this study, occupy roughly the northern half of this complex. The Malhaq Formation records several phases of Ediacaran sedimentation and volcanic activity (615-607 Ma), whereas Um Zariq Formation metasediments are relicts of an older sedimentary sequence (Cryogenian; 813±6 Ma). The Malhaq Formation comprises a series of dark gray structureless to schistose felsic to intermediate metavolcanics interbedded and intercalated with fine- to medium-grained foliated mica-rich phyllites and schists, while the Um Zariq Formation is a dominantly metasedimentary sequence, mainly represented by well-bedded metapelitic schists. Malhaq metasediments are enriched in SiO2, CaO and K2O and depleted in TiO2, Al2O3 and K2O relative to those of Um Zariq Formation. Aside from the relatively low Ni and Cr concentrations, compatible transition elements of these metasediments are comparable to average crustal contents. Except for marked Sr depletion, LILEs are around average continental crust values. Pronounced negative Nb-Ta anomalies in all samples, and general enrichment of Um Zariq samples in Th, U, Zr, Ti and Y relative to Malhaq ones are the main features of HFSEs. The REE patterns of all samples are parallel to sub-parallel LREE-enriched, with distinct negative Eu anomalies and weakly fractionated HREE segments. Geochemical investigations have revealed that the source rocks of Malhaq Formation metasediments underwent mild to moderate chemical weathering, whereas those of Um Zariq Formation have suffered severe chemical weathering. These metasediments are predominately derived from felsic to intermediate igneous sources, with a particular slight addition from recycled sedimentary source to the Malhaq Formation metasediments. They are collectively geochemically immature and have suffered minor sedimentary recycling, with the bearing of Malhaq Formation metasediments from advanced degree of sorting and reworking. The Malhaq and Um Zariq metasediments had been originally deposited in a continental arc setting, most probably back-arc basin, despite the wide time span between their individual depositions. Various geochemical evidences imply that the main source from which these two chronologically distinct metasediments (Ediacaran vs. Cryogenian) have been derived from the juvenile (arc-type) Arabian-Nubian Shield crust.

    The studies of benthic calcareous foraminifera of the Maastrichtian-early Paleocene Dakhla Formation in Gebel Um El-Ghanayem (Western Desert, Egypt), improve reconstruction of depositional environments of these successions. In total, 68 taxa of benthic foraminifera were identified in the studied succession. The late Maastrichtian assemblages (Zone CF3) are dominated by calcareous foraminifera with tapered tests, this tapered taxon Loxostomum applinae, Lox. tegulatum various dentalinid taxa, and Buliminella cushmani dominate in CF3 Biozone. We thus interpret these faunas as being dominated by infaunal morphogroups, suggesting a moderately eutrophic environment. Danian assemblages are characterized by abundant epifaunal trochospiral species, such as Cibicidoides abudurbensis, Cibicidoides farafraensis, and Gyroidinoides girardanus. The infaunal morphogroups make up 25-47% of fauna in the Danian, in contrast to 62-76% in the Upper Maastrichtian. This dominance of the Danian benthic foraminiferal assemblages by epifaunal or mixed epifaunal/infaunal morphogroups suggests that the food supply to the benthos was less abundant than in the latest Cretaceous. The Cretaceous/Paleocene boundary (K/Pg) is within the upper unit of the Lower Kharga Member and marked by a hiatus in at least the top of CF3 Zone of the Upper Maastrichtian to the Lower Paleocene (base Plc Zone).

  9. Banded iron formations of Um Nar, Eastern Desert of Egypt: P-T-X conditions of metamorphism and tectonic implications

    2014-05-01

    Banded iron formations (BIF) in Um Nar, central eastern desert of Egypt, occur intercalated with schists of volcaniclastic and epiclastic origins within "ophiolitic-island arc rocks" of the Arabo-Nubian Shield. The BIF and its host rocks were affected by folding, thrusting, and regional metamorphism during the Pan-African Orogeny resulting in the development of north-verging overturned folds and E-W striking, S-dipping thrusts. Following the intrusion of granitoids, the entire sequence was refolded into south-plunging folds with NW-SE trending fold axes. Peak mineral assemblages of hornblende + plagioclase, and garnet + biotite + plagioclase + quartz in the host rocks, and andradite-rich garnet + epidote + hematite + magnetite + quartz in the BIF indicate metamorphism under epidote amphibolite facies conditions. Using the multiequilibrium approach of Thermocalc, and conventional thermobarometry, peak P-T conditions of metamorphism are estimated at 520 ± 30 °C, 5 ± 2 kbar. Fluids attending peak conditions in the oxide facies layers of the BIF were characterized by XCO2 ~ 0.03 and log fO2 ~ - 40. Textural and mineral chemical criteria suggest that, following peak conditions, the rocks underwent a stage of near-isobaric cooling or cooling and compression characteristic of a counter-clockwise P-T path.

    We present [Fe II] 1.64 um imaging observations for jets and outflows from young stellar objects (YSOs) over the northern part (~24'x45') of the Carina Nebula, a massive star forming region. The observations were performed with IRIS2 of Anglo-Autralian Telescope and the seeing was ~1.5". Several jets and outflows features are detected at eight different regions, and named as forbidden emission line regions (FELRs). One new candidate for Herbig-Haro Object is identified comparing our [Fe II] images to H_alpha images of Hubble Space Telescope. FELRs have knotty or longish shapes, and distribute around the triangular area formed by three star clusters Tr 14, Tr 15, and Tr 16, which contain many massive stars. The detection rate of FELRs against previously identified YSOs is 1.4 %. We estimate the outflow rate from the [Fe II] flux based on some assumptions. The jet-driving objects are identified for three FELRs (FELR-2, -4, and -7), for which we study the relations between the outflow rate and the YSO physical parameters from the radiative transfer model fitting. The ratios of the outflow rate over the disk accretion rate are consistent for FELR-4 and -7 with the previously reported values, while it is higher for FELR-2. The masses of jet-driving objects are low or intermediate, and they are not likely to become massive stars (> 8 Ms). Other YSO physical parameters, such as luminosity and age, show reasonable relations or trends.

    We present an initial analysis of AKARI 18um-selected galaxies using all 9 photometric bands at 2-24um available in the InfraRed Camera (IRC), in order to demonstrate new capabilities of AKARI cosmological surveys. We detected 72 sources at 18um in an area of 50.2 arcmin^2 in the AKARI/IRC monitor field towards the North Ecliptic Pole (NEP). From this sample, 25 galaxies with probable redshifts z>~ 0.5 are selected with a single colour cut (N2-N3>0.1) for a detailed SED analysis with ground-based BVRi'z'JK data. Using an SED radiative transfer model of starbursts covering the wavelength range UV -- submm, we derive photometric redshifts from the optical-MIR SEDs of 18um-selected galaxies. From the best-fit SED models, we show that the IRC all-band photometry is capable of tracing the steep rise in flux at the blue side of the PAH 6.2um emission feature. This indicates that the IRC all-band photometry is useful to constrain the redshift of infrared galaxies, specifically for dusty galaxies with a less prominent 4000A break. Also, we find that the flux dip between the PAH 7.7 and 11.2um emission feature is recognizable in the observed SEDs of galaxies at z~1. By using such a colour anomaly due to the PAH and silicate absorption features, unique samples of ULIRGs at z~1, `silicate-break' galaxies, can be constructed from large cosmological surveys of AKARI towards the NEP, i.e. the NEP-Deep and NEP-Wide survey. This pilot study suggests the possibility of detecting many interesting galaxy properties in the NEP-Deep and Wide surveys, such as a systematic difference in SEDs between high- and low-z ULIRGs, and a large variation of the PAH inter-band strength ratio in galaxies at high redshifts.

    2012-01-01

    Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Phased Array L-band Synthetic Aperture Radar (PALSAR) images covering the Um Rus area in the Central Eastern Desert of Egypt were evaluated for mapping geologic structure, lithology, and gold-related alteration zones. The study area is covered by Pan-African basement rocks including gabbro and granodiorite intruded into a variable mixture of metavolcanics and metasediments. The first three principal component analyses (PCA1, PCA2, PCA3) in a Red-Green-Blue (RGB) of the visible through shortwave-infrared (VNIR + SWIR) ASTER bands enabled the discrimination between lithological units. The results show that ASTER band ratios ((2 + 4)/3, (5 + 7)/6, (7 + 9)/8) in RGB identifies the lithological units and discriminates the granodiorite very well from the adjacent rock units.The granodiorites are dissected by gold-bearing quartz veins surrounded by alteration zones. The microscopic examination of samples collected from the alteration zones shows sericitic and argillic alteration zones. The Spectral Angle Mapper (SAM) and Spectral Information Divergence (SID) supervised classification methods were applied using the reference spectra of the USGS spectral library. The results show that these classification methods are capable of mapping the alteration zones as indicated by field verification work. The PALSAR image was enhanced for fracture mapping using the second moment co-occurrence filter. Overlying extracted faults and alteration zone classification images show that the N30E and N-S fractures represent potential zones for gold exploration. It is concluded that the proposed methods can be used as a powerful tool for ore deposit exploration.

  17. A newly discovered DLA and associated Ly? emission in the spectra of the gravitationally lensed quasar UM673A,B

    The sightline to the brighter member of the gravitationally lensed quasar pair UM673A,B intersects a damped Ly? system (DLA) at z = 1.62650 which, because of its low redshift, has not been recognized before. Our high-quality echelle spectra of the pair, obtained with HIRES on the Keck I telescope, show a drop in neutral hydrogen column density N(HI) by a factor of at least 400 between UM673A and UM673B, indicating that the DLA's extent in this direction is much less than the 2.7 h-170kpc separation between the two sightlines at z = 1.62650. By re-assessing this new case together with published data on other quasar pairs, we conclude that the typical size (radius) of DLAs at these redshifts is R ~= (5 +/- 3) h-170kpc, smaller than previously realized. Highly ionized gas associated with the DLA is more extended, as we find only small differences in the CIV absorption profiles between the two sightlines. Coincident with UM673B, we detect a weak and narrow Ly? emission line which we attribute to star formation activity at a rate SFR >~ 0.2Msolaryr-1. The DLA in UM673A is metal poor, with an overall metallicity ZDLA ~= 1/30Zsolar, and has a very low internal velocity dispersion. It exhibits some apparent peculiarities in its detailed chemical composition, with the elements Ti, Ni and Zn being deficient relative to Fe by factors of 2-3. The [Zn/Fe] ratio is lower than those measured in any other DLA or Galactic halo star, presumably reflecting somewhat unusual previous enrichment by stellar nucleosynthesis. We discuss the implications of these results for the nature of the galaxy hosting the DLA. Based on data obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and NASA, and was made possible by the generous financial support of the W.

    1983-01-01

    The stacking equilibrium quotient of the m7G5'pppUm unit, which occurs as the 5'-terminal "cap" of certain eukaryotic mRNA's, was determined by temperature-dependent difference spectrophotometry as Kstack = 1.82 at 25 degrees and pH 5. In order to evaluate the contribution of different structural modifications to the net stabilization of the cap structures of mRNA, a variety of compounds related to m7G5'pppUm were synthesized and their stacking properties were studied by the same method and compared. The results are summarized as: (1) Introduction of a methyl group into N-7 of G residue results in an increase in base stacking. (2) Methylation at 2'-OH of U residue also stabilizes the stacked structure of G-containing dimers, but it does not influence stacking interaction in m7G-containing dimers. (3) The effect of different types of internucleotide linkages on the order of stacking tendencies is: N5'ppN' greater than N5'pppN' greater than NpN'. UV hypochromicity and CD spectral measurements of the relevant dimers were also conducted, and the hypochromicity values and CD spectra of dimers in their stacked conformation were estimated by making use of the determined Kstack values. The results indicate that, while 2'-O-methylation exerts very little effect on the stacked conformation of the dimers, methylation at N-7 and the nature of the internucleotide linkage strongly influence the stacked conformation, thereby forming unusual left-handed conformations in m7G5'pppU(m), m7G5'ppU(m), and G5'ppU(m).

    The purpose of this project was to design and implement a pipeline Analog-to-Digital Converter using 0.35um CMOS technology. Initial requirements of a 25-MHz conversion rate and 8-bits of resolution where the only given ones. Although additional secondary goals such as low power consumption and small area were stated. The architecture is based on a 1.5 bit per stage structure utilizing digital correction for each stage [12]. A differential switched capacitor circuit consisting of a cascade gm-C op-amp with 200MHz ft is used for sampling and amplification in each stage [12]. Differential dynamic comparators are used to implement the decision levels required for the 1.5-b per stage structure. Correction of the pipeline is accomplished by using digital correction circuit consist of D-latches and full-adders. Area and Power consumption of whole design was 0.24mm2 and 35mW respectively. The maximum sample rate at which the converter gave an adequate output was 33MHz.

  4. Total ionizing dose radiation hardness of the ATLAS MDT-ASD and the HP-Agilent 0.5 um CMOS process

    2002-01-01

    A total ionizing dose (TID) test of the MDT-ASD, the ATLAS MDT front-end chip has been performed at the Harvard Cyclotron Lab. The MDT-ASD is an 8-channel drift tube read-out ASIC fabricated in a commercial 0.5 um CMOS process (AMOS14TB). The accumulated TID at the end of the test was 300 krad, delivered by 160 MeV protons at a rate of approximately 70 rad/sec. All 10 irradiated chips retained their full functionality and performance and showed only irrelevantly small changes in device parameters. As the total accumulated dose is substantially higher than the relevant ATLAS Radiation Tolerance Criteria (RTCtid), the results of this test indicate that MDT-ASD meets the ATLAS TID radiation hardness requirements. In addition, the results of this test correspond well with results of a 30 keV gamma TID irradiation test performed by us on an earlier prototype at the CERN x-ray facility as well as with results of other irradiation test on this process found in literature.

    During two color sensor fusion it is found that an electric time delay and integration (TDI) circuit can be replaced by an equivalent optical TDI method. This contains a dichroic mirror to separate dual wavebands into two image focal planes with a two-dimensional image translation between the image focal planes. The experimental result shows that performance of the fusion sensor is improved with an increased video signal to noise ratio and a lower minimum resolvable temperature difference. It can also provide a real time (30 frames) single enhanced dual band thermal image.

    Because of its high power and excellent optical features, laser has almost been applied to everywhere of medical research and clinic. Over the past several years, laser medical has achieved a rapid progress, and laser medical instruments has developed promptly, each new wavelength can be successfully applied in diagnostic and treatment of diseases. Among the medical lasers, Nd:YAG solid-state laser systems have proven useful in surgical use operate, such as neurosurgery, gastroenterology, cardioangiology, urology, gynecology, dermatology and ENT. As with other solid-state lasers, the Nd:YAG laser can be made to emit various wavelengths by means of suitable resonator configurations and some newest solid-state laser technology, pumped by the Krypton lamp, the Nd:YAG laser at room temperature exhibits transition at 1.06 micrometer Nd:YAG, using nonlinear crystal and Q-switch to double its frequency can attain 0.53 micrometer green beam. In our laser systems, the efficiency at 1.06 micrometer is more than 3 percent, an efficiency of 0.5 percent at 1.32 micrometer and 0.53 micrometer can be attained. For a power of 100w at 1.06 micrometer, 15w at 1.32 micrometer and 0.53 micrometer can therefore be produced. All of three kinds Nd:YAG laser hold these characteristics: high output power; optical fiber transition that can be cooperated with endoscope. The paper mainly discusses laser operating characteristics and clinic applications of three kinds wavelengths at 0.53 micrometer 1.06 micrometer and 1.32 micrometer Nd:YAG laser systems.

  11. Astronomy around 1700. (German Title: Astronomie um 1700)

    NASA Astrophysics Data System (ADS)

    Herbst, Klaus-Dieter

    The book focuses on Gottfried Kirch und Olaus Römer, two scholars who played a leading role in astronomy around 1700. It contains an annotated edition of the letter by Gottfried Kirch to Olaus Römer of October 25, 1703. Kirch was the astronomer of the Berlin Academy of Sciences since 1700, recognized both as astronomical calculator and as observer - Römer was director of the Copenhagen Observatory and was the first who determined the speed of light. Kirch's letter to Römer of October 1703, given here together with several addenda, was not a letter in the modern sense, but a treatise of broad contents, dealing with different astronomical items of that time: the problem of determining stellar and planetary positions, the subjective view on contemporaries, the methods of astronomical calculations, the discovery of comets and other questions are described in Kirch's vivid words. Numerous annotations by the editor explain the astronomy of that time. The editor leads the reader step by step through the methods of astronomical calculations, which become clear and understandable. A complete bibliography of works by and about Kirch and a list of known archival sources are added.

    Superconducting tunnel junctions coupled to superconducting absorbers may be used as high-resolution, high-efficiency X-ray spectrometers. We have tested devices with niobium X-ray absorbing layers coupled to aluminum layers that serve as quasiparticle traps. In this work we measured the current pulses from a large area tunnel junction using an amplifier based on an array of 100 SQUIDs. Using this amplifier and a 282 micron X 282 micron junction, we have measured an energy resolution of 19 eV FWHM for 1.5 keV X rays and 21 eV for 2.6 keV X rays. The area of this junction is eight times the area of any junction previously measured to have such high energy resolution.

    There are an increasing number of researches in science education that affirm the importance of discussions on the "nature of science" in basic education level as well as in teacher training. The history of science applied to education is a way to contextualize epistemological discussions, allowing both the understanding of scientific content and learning about science concepts. We present some reasonably consensual definitions on the nature of science that have been widely discussed by the academic community. We show also some episodes in the history of astronomy which can lead to discussions involving some aspects of the nature of science, and how they can do it. Hay un número creciente de investigaciones en la enseñanza de las ciencias que afirman la importancia de debates sobre la "naturaleza de la ciencia" en la educación básica y formación del profesorado. La historia de la ciencia aplicada a la educación es una manera de contextualizar los debates de la epistemología, lo que permite tanto la comprensión de los contenidos científicos como el aprendizaje de conceptos científicos. En esto trabajo, presentamos algunas definiciones bastante consensuales sobre la naturaleza de la ciencia que han sido ampliamente discutidas por la comunidad académica y mostramos cómo algunos episodios en la historia de la astronomía pueden llevar a discusiones sobre algunos aspectos de la naturaleza de la ciencia. Há um número crescente de pesquisas na área de ensino de ciências que afirmam a importância de discussões sobre a "natureza da ciência" na educação básica e na formação de professores. A história da ciência aplicada ao ensino é uma maneira de contextualizar discussões epistemológicas, permitindo tanto a compreensão de conteúdos científicos quanto o aprendizado de noções sobre as ciências. Neste trabalho apresentamos algumas definições razoavelmente consensuais sobre a natureza da ciência que foram amplamente discutidas pela comunidade acadêmica e mostramos como alguns episódios da história da astronomia podem levar a discussões envolvendo alguns dos aspectos da natureza da ciência.

    Often corporations need tools to improve their decision making in a competitive market. In general, these tools are based on data warehouse platforms to mange and analyze large amounts of data. However, several of these corporations do not have enough resources to buy such platforms because of the high cost. This work is dedicated to a feasibility study of a low cost platform to data warehouse. We consider as a low cost platform the use of open source software like the PostgreSQL database system and the GNU/Linux operational system. We verify the feasibility of this platform by executing two benchmarks that simulate a data warehouse workload. The workload reproduces a multi-user environment with the execution of complex queries, which executes: aggregations, nested sub queries, multi joins, in-line views and more. Considering the results we were able to highlight some problems on the PostgreSQL database system, and discuss improvements in the context of data warehouse.

    New I-line resists are claimed to be usable at 0.35 micrometers design rules. We have examined the suitability of several such materials (JSR IX750, Sumitomo PFi-38a, OCG RX64I) for this purpose and compared them with our production 0.5 micrometers resist, JSR IX700. A variety of criteria have been used, including the measured focus exposure windows at e-min and e-max, DOF vs. CD for grouped and isolated lines as well as contacts, linearity, and proximity response as a function of pitch. A limited study has been done on the impact of embedded phase shift reticles on printing small geometry contacts. We report upon the process improvements observed with two different reticle transmissions, their impact on isofocal bias, as well as the issue of sidelobe formation. Proponents of DUV claim that modern DUV materials exhibit significant advantages in terms of process window and more over are applicable to smaller geometries without the need for supplementary techniques such as phase shifting or modified illumination. In this study, we have examined the performance of a number of DUV materials (BASF ST3.5, OCG ARCH, JSR KRFL2 and an as yet experimental JSR resists) on ASM-L and Nikon excimer laser steppers. Limited results were also obtained using Shipley 2408 and dyed XP-9444 (0.8) on the SVG Micrascan II. Our studies conclude with a comparison of the CD swing observed over a variety of chemically mechanically planarized steps. This has been done for selected I-line and DUV resists with the aid of a TAR or BARC or as in the case of the broad band SVG system either a BARC or a dyed resist.

    1995-05-01

    The manufacturing of high performance integrated circuits requires tight control of critical dimensions (CD) at poly pattern. Achieving these CD requirements forces process engineers to eliminate linewidth variation caused by reflective notching and thin film effects. Implementation of a bottom antireflective coating (BARC) can reduce or eliminate linewidth variations caused by reflective notching and thin film effects. With the additional process complexity, a number of issues must be resolved to obtain the true benefits of using a BARC material. The following paper discusses the characterization of a commercially available BARC material for 0.35 micrometers i-line poly patterning. Initial characterization of gratings and isolated lines on flat poly test wafers shows the resist process with BARC to have equal and in some cases better process capability compared to a conventional resist process. An 800 angstrom BARC film thickness on flat silicon wafers reduces the amplitude of the resist swing curve by 75%. On topography wafers an 800 angstrom BARC thickness eliminates reflective notching although for some small feature sizes, thin film effects still cause linewidth nonuniformity. Evaluations of BARC thicknesses ranging from 800 angstrom to 2,400 angstrom demonstrate the capability of the BARC to eliminate the swing effect in the resist by optimization of the BARC thickness. Cross sections of the resist profiles before and after etch demonstrate the ability for a repeatable pattern transfer. Wafer-to-wafer data and lot- to-lot data show the successful development of an etch process with a 0.03 micrometers bias. The data presented demonstrates the implementation of an optimized BARC process enhances the CD control capability at poly patterning for 0.35 micrometers i-line processing.

    2009-02-01

    Advanced application of Er:YAG laser radiation in medical treatment requires a suitable, very precise delivery of this light to a target. In some cases (urology, cardiology, or endodontic treatments), thin waveguides are needed. Therefore a preliminary investigation was conducted with 250/360 ?m inner/outer diameter hollow glass waveguides. The waveguide has inner coating made from cyclic olefin polymer and silver layers. All delivery systems were simple and consisted of lens, protector, and the waveguide. The laser source was the Er:YAG system working in a free-running regime and generating radiation at 2.94 ?m wavelength. For testing, output laser energy up to 100 mJ with a repetition rate of 1 Hz was chosen. The output laser spatial profile was approximately TEM00 mode, so the structure changes behind the delivery system were readily detected. The energy delivery characteristics were also checked, and the transmission reached 77%. The maximum input fluence into the waveguide was 200 mJ/cm2, and no significant damages to waveguides were observed after the measurements.

    Large scientific collaborations as well as universities have a growing need for multimedia archiving of meetings and courses. Collaborations need to disseminate training and news to their wide-ranging members, and universities seek to provide their students with more useful studying tools. The University of Michigan ATLAS Collaboratory Project has been involved in the recording and archiving of multimedia lectures since 1999. Our software and hardware architecture has been used to record events for CERN, ATLAS, many units inside the University of Michigan, Fermilab, the American Physical Society and the International Conference on Systems Biology at Harvard. Until 2006 our group functioned primarily as a tiny research/development team with special commitments to the archiving of certain ATLAS events. In 2006 we formed the MScribe project, using a larger scale, and highly automated recording system to record and archive eight University courses in a wide array of subjects. Several robotic carts are wheeled around campus by unskilled student helpers to automatically capture and post to the Web audio, video, slides and chalkboard images. The advances the MScribe project has made in automation of these processes, including a robotic camera operator and automated video processing, are now being used to record ATLAS Collaboration events, making them available more quickly than before and enabling the recording of more events.

    Theoretical and experimental analysis of the efficiency of application of 2 micrometers pulsed holmium laser for cosmetic and plastic surgery and dermatology is carried out. Preliminary experiments were carried out on rats. Solid state 2 micrometers pulsed laser was allowed to operate in free running mode with pulse energy up to 1.5 J and pulse repetition rate up to 5 Hz. To deliver emission to the object a flexible quartz fiber without further focusing of 2.5 m in length and 400 micrometers of the core diameter was used. The effect of the different power density emission on the skin was studied. The second stage was the study of the influence of 2 micrometers emission on human skin. The results of the removal of hemangioma, papilloma, telangiectasia, nevus, nevus acantholytic, xanthelasma palpebral, verruca, chloasma, pigmental spots, tattoos, etc. are presented. Precision, simplicity, efficiency, and the high cosmetic effect of these operations is noted.

    The use of di-functional monomers such as 2,6- Bis(hydroxymethyl)-p-cresol has allowed the design of novolak resins having alternating architecture with enhanced o,o'-bonding order, specific end-groups and narrow molecular weight distribution. When compared with a conventional m-\\/p- cresol formaldehyde novolak, the new resins have a lower molecular weight and molecular weight distribution with no p-cresol enriched oligomer fractions.

    Mineral chemistry and typomorphic characteristics are used to monitor the physicochemical evolution of late-magmatic to postmagmatic alteration processes that resulted in the development of a radioactive and albite-enriched microgranite shock. The mineral paragenesis indicates that postmagmatic fluids were enriched in Nb, Zn, U, Th, Zr, and Y, in addition to Rb, Li, and F. Manganocolumbite with extremely high Nb/(Nb+Ta) (0.99), Mn/(Mn+Fe) (0.82), and zircon with high Zr/(Zr+Hf) (0.97) indicate crystallization under alkaline, relatively high-temperature conditions (>425{degrees}C). The close association of manganocolumbite, Nb-Mn-Zn-rich ilmenite (with 1.2 to 14.5 wt% ZnO), spessartine garnet (with 68.2-89.4 mol% spessartine), zircon, xenotime, zinnwaldite mica (up to 5.98 wt% F), and fluorite indicates the strong affinity of the elements of Nb, Y, Zr, Mn, and Zn for stable complexing by K{sup +}, Na{sup +}, Li{sup +}, and F{sup -}-rich supercritical fluids during the course of extraction and transportation. The enrichment of the interacting fluid in U and Th is depicted by the presence of up to 1.6% UO{sub 2} in manganocolumbite and Hf-bearing zircon, and up to 10.5% ThO{sub 2} in monazite, in addition to locally abundant thorite and uranophane. It is suggested that the uranium mineralization, mainly as fracture fillings, formed during the waning stage of hydrothermal activity. 30 refs., 5 figs., 2 tabs.

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

    The GOSSIP (Gas On Slimmed Silicon Pixel) detector is a proposed alternative for silicon based pixel detectors. The Gossip Prototype (GOSSIPO) chip is being developed to serve as a prototype read-out chip for such a gas-filled detector. Thanks to the very low capacitance at the preamplifier input, the front-end of the chip demonstrates low-noise performance in combination with a fast peaking time and low analog power dissipation. Measurement of the drift time of every primary electron in the gas volume enables 3D reconstruction of the particle tracks. For this purpose a Time-to- Digital converter must be placed in each pixel. A small-scale prototype of the GOSSIP chip has been developed in the 0.13 ?m CMOS technology. The prototype includes a 16 by 16 pixel array where each pixel is equipped with a front-end circuit, threshold DAC, and a 4-bit TDC. The chip is available for testing in May 2007 and after initial tests it will be postprocessed to build a prototype detector. This paper describes the detector de...

The gamma spectra were collected by a HPGe detector and the analysis was done by a computerized multichannel analyzer.The accuracy of the procedure is evaluated by the analysis of two geo-standard reference materials (Dolerite WSE and Microgabro PMS). The choice of the nuclear reaction, irradiation and decay times and of the proper gamma radiation in counting are presented and discussed. The data presented here are our contribution to understanding the elemental composition of the quartz rock. Because there are no existing databases for the elemental analysis of quartz, our results are a start to establishing a database for the Egyptian quartz. It is hoped that the data presented here will be useful to those dealing with geochemistry, quartz chemistry and related fields. PMID:23954747

  12. Calibration and performance evaluation of a portable shortwave infrared (1.05- to 2.45-um) spectrometer

    Smith, Mark W.; Biggar, Stuart F.

    1994-11-01

    A portable shortwave infrared spectrometer has been developed that covers the range from 1.05 to 2.45 micrometers . The spectral sampling interval is 1.37 nm, and the spectral resolution can be varied from about 5 nm to more than 100 nm. A single spectrum can be acquired in as little as 1 s. The signal-to-noise ratio (SNR) for a single 1-s scan is about 100 at a wavelength of 2.2 micrometers for a lambertian surface of 100% reflectance illuminated by the sun at normal incidence with 14-nm spectral resolution. The SNR at 1.25 micrometers is about 900 for the same conditions. The estimated 1(sigma) uncertainty in the absolute radiometric calibration of the instrument is 2% to 3%. Field-of-view defining optics are coupled by a flexible fiber optic bundle to the spectrometer, which consists of a nonscanning concave holographic diffraction grating with a flat focal field imaged onto a 1024-element liquid nitrogen cooled PtSi linear array detector. The primary use for the instrument is the collection of ground reflectance and radiance data for the radiometric calibration of operational and proposed high spectral resolution remote sensing systems.

    Cadmium Zinc Telluride and Cadmium Telluride are the detector materials of choice for the detection of X-rays in the X-ray energy band E >= 5keV with excellent spatial and spectral resolution and without cryogenic cooling. Owing to recent breakthroughs in grazing incidence mirror technology, next-generation hard X-ray telescopes will achieve angular resolution between 5 and 10 arc seconds - about an order of magnitude better than that of the NuSTAR hard X-ray telescope. As a consequence, the next generation of X-ray telescopes will require pixelated X-ray detectors with pixels on a grid with a lattice constant of science drivers for a high angular-resolution X-ray mission include studies and measurements of black hole spins, the cosmic evolution of super-massive black holes, active galactic nuclei feedback, and the behaviour of matter at very high densities.

    We use a stratosphere-troposphere composition-climate model with interactive sulfur chemistry and aerosol microphysics, to investigate the effect of the 1991 Mount Pinatubo eruption on stratospheric aerosol properties. Satellite measurements indicate that shortly after the eruption, between 14 and 23 Tg of SO2 (7 to 11.5 Tg of sulfur) was present in the tropical stratosphere. Best estimates of the peak global stratospheric aerosol burden are in the range 19 to 26 Tg, or 3.7 to 6.7 Tg of sulfur assuming a composition of between 59 and 77 % H2SO4. In light of this large uncertainty range, we performed two main simulations with 10 and 20 Tg of SO2 injected into the tropical lower stratosphere. Simulated stratospheric aerosol properties through the 1991 to 1995 period are compared against a range of available satellite and in situ measurements. Stratospheric aerosol optical depth (sAOD) and effective radius from both simulations show good qualitative agreement with the observations, with the timing of peak sAOD and decay timescale matching well with the observations in the tropics and mid-latitudes. However, injecting 20 Tg gives a factor of 2 too high stratospheric aerosol mass burden compared to the satellite data, with consequent strong high biases in simulated sAOD and surface area density, with the 10 Tg injection in much better agreement. Our model cannot explain the large fraction of the injected sulfur that the satellite-derived SO2 and aerosol burdens indicate was removed within the first few months after the eruption. We suggest that either there is an additional alternative loss pathway for the SO2 not included in our model (e.g. via accommodation into ash or ice in the volcanic cloud) or that a larger proportion of the injected sulfur was removed via cross-tropopause transport than in our simulations. We also critically evaluate the simulated evolution of the particle size distribution, comparing in detail to balloon-borne optical particle counter (OPC) measurements from Laramie, Wyoming, USA (41° N). Overall, the model captures remarkably well the complex variations in particle concentration profiles across the different OPC size channels. However, for the 19 to 27 km injection height-range used here, both runs have a modest high bias in the lowermost stratosphere for the finest particles (radii less than 250 nm), and the decay timescale is longer in the model for these particles, with a much later return to background conditions. Also, whereas the 10 Tg run compared best to the satellite measurements, a significant low bias is apparent in the coarser size channels in the volcanically perturbed lower stratosphere. Overall, our results suggest that, with appropriate calibration, aerosol microphysics models are capable of capturing the observed variation in particle size distribution in the stratosphere across both volcanically perturbed and quiescent conditions. Furthermore, additional sensitivity simulations suggest that predictions with the models are robust to uncertainties in sub-grid particle formation and nucleation rates in the stratosphere.

    Wafer-bonded AlAs/GaAs mirrors and AlGaInAs strain- compensated multiple quantum well active layers have been applied into 1.3 micrometer vertical-cavity surface-emitting lasers (VCSELs). Double-bonded 1.3 micrometer VCSELs have operated at room temperature pulsed conditions with a high output power of 4.6 mW, a high characteristic temperature of 132 K, and a large side-mode suppression-ratio of 42 dB. A novel more practical approach for 1.3 micrometer VCSELs have been proposed and demonstrated a very low room temperature pulsed threshold current density of 1.13 kA/cm2 and a very low threshold current of 2 mA. Further improvement focusing on practical approaches for long wavelength VCSELs is underway.

    A process for the fabrication of surface acoustic wave (SAW) devices with line widths of 250 nm and less, based on x-ray lithography using a laser-plasma source has been developed. The x-ray lithography process is based on keV x-ray emission from Cu plasma produced by 15 Hz, 50 ps, 248 nm KrF excimer laser pulses. The full structure of a 2 GHz surface acoustic wave filter with interdigital transducers in a split-electrode geometry has been manufactured. The devices require patterning a 150 nm thick aluminum layer on a LiNbO3 substrate with electrodes 250 nm wide. The manufacturing process has two main steps: x-ray mask fabrication employing e-beam lithography and x-ray lithography to obtain the final device. The x-ray masks are fabricated on 1 micrometers thick membranes of Si2N4. The line patterns on the masks are written into PMMA resist using a scanning electron microscope which has been interfaced to a personal computer equipped to control the x and y scan voltages. The opaque regions of the x-ray mask are then formed by electroplating fine grain gold into the open spaces in the etched PMMA. The mask and sample are mounted in an exposure cassette with a fixed spacer of 10 micrometers separating them. The sample consists of a LiNbO3 substrate coated with Shipley XP90104C x-ray resist which has been previously characterized. The x-ray patterning is carried out in an exposure chamber with flowing helium background gas in order to minimize debris deposition on the filters. After etching the x-ray resist, the final patterns are produced using metallization and a standard lift-off technique. The SAW filters are then bonded and packaged onto impedance matching striplines. The resultant devices are tested using Scalar Network Analyzers. The final devices produced had a center frequency of 1.93 GHz with a bandwidth of 98 MHz, close to the expected performance of our simple design.

    Um interessante fenômeno lingüístico presente nas interações das pessoas bilíngues é a alternância de línguas. Neste trabalho, estamos investigando a alternância entre a língua portuguesa oral e a língua de sinais brasileira – Libras, numa mesma cadeia enunciativa, com o objetivo de identificar e analisar o uso dessa alternância na fala de uma criança e de um adulto (ambos ouvintes, filhos de pais surdos), interagindo em uma situação de bilinguismo intermodal, com interlocutores surdos e ouvintes. A alternância de línguas, nesse caso, ocorre quando se para de falar em português e se alterna para sinalizar. O presente trabalho se caracteriza como um estudo inicial, com análise qualitativa de dados. Fazem parte do nosso corpus nove sessões de interações em Libras e em português oral, gravadas em vídeo, que fazem parte do Projeto Desenvolvimento Bilíngue Bimodal da UFSC. Os dados revelam que as características da alternância de línguas pelo adulto e pela criança parecem ter semelhanças e diferenças. O sujeito adulto parece ter feito um uso da alternância mais preocupado com o curso da interação. A criança, por sua vez, não parece tê-la usado com propósitos pragmáticos específicos. Quanto à extensão das alternâncias, pode-se perceber que tanto a criança quanto o adulto utilizaram enunciados maiores do que uma única palavra isolada. O papel dos interlocutores parece ter sido decisivo nas interações aqui investigadas – especialmente nas do adulto, já que a criança ainda está em processo de tomada de consciência do papel do interlocutor na interação.

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

    A Vectra IMPTM (Ion Metal Plasma) source was used to deposit TiN films for application such as W plug liner and Al wetting layer. The process is based on conventional magnetron sputtering with the addition of a higher density, inductively coupled RF plasma between the sputtering cathode and the substrate. This new technology enables deposition of the films into deep submicron contacts with >50% bottom coverage. In addition to enhancing step coverage of metal films, such as Ti and TiN, this process also has significant effects on the materials properties of the films. The film properties of the TiN films were studied as a function of the fundamental process parameters, namely DC target power, RF coil power, and chamber process pressure, using statistical DOE technique. The study shows that a high degree of control over the film properties can be obtained in the IMP process.

    Ti/TiN liners deposited with Vectra IMPTM (Ion Metal Plasma) PVD technology can be used as wetting layers to lower the temperature of Al planarization. The Ti/TiN liners can also be used to improve the texture and morphology of the Al overlayer. An experimental investigation was performed to study the impact of the IMP PVD process on the wetting properties of the Ti/TiN films. The Ti/TiN underlayers and the Al overlayer were studied for film morphology and texturing using AFM, XRD, and TEM techniques. It was found that the IMP Ti/TiN process can be used to control and optimize the fill capabilities of low temperature Al planarization. Parameters such as process pressure, bias, process temperature of the IMP Ti and TiN process as well as the wetting layer thickness have significant effects on the grain size, reflectivity, crystal orientation, and surface roughness of the aluminum films. Al films with high reflectivity, low roughness and hyper texturing (< 1 degree(s) FWHM) have been obtained with the integration of IMP Ti/TiN liner module with a low temperature Al planarization module. The fill capability of this integrated process exceeds that of the conventional high temperature Al planarization process at the Via level for a sub 0.25 micrometers IC process.

    NASA's Stardust mission collected dust from the coma of Comet Wild-2 on January 2nd, 2004, by direct capture into aerogel cells that flew through the dust coma at 6 km/s. Stardust collected several hundred comet particles >10 {mu}m in size. These comet samples were delivered to Earth on January 15th, 2006. We developed a facility at the National Synchrotron Light Source at Brookhaven National Laboratory (Upton, NY, USA) for the in-situ characterization of 10 {mu}m particles collected in aerogel. These analytical instruments allow us to perform extensive chemical, mineralogical, and size-frequency characterization of particles captured in aerogel. These analyses are conducted without any invasive extraction, minimizing the possibility of contamination or particle loss during preparation. This facility was used to determine the chemical composition, the oxidation state, the mineralogy and to provide an indication of the grain size of the Wild-2 particles before they were removed from the aerogel. This information provides a catalog of particle types, allowing a more reasoned allocation of the particles to subsequent investigators based on a relatively detailed knowledge of the chemical composition and mineralogy of each particle. These measurements allowed a comparison of the chemical and mineralogical properties of the Wild-2 particles with other types of extraterrestrial materials, including interplanetary dust particles and meteorites. The success of in-situ analysis for Wild 2 particles demonstrates that synchrotron-based facilities will be important for the analysis of particles collected in aerogel on future earth-orbiting satellites and spacecraft.

    Laser irradiation of mechanically deformed cartilage results in permanent shape change. Under optimal conditions, the cartilage graft must be rapidly heated to the critical transition temperature, required for reshaping, while maintaining a spatially uniform temperature distribution. These two conditions are not easily satisfied, as increasing irradiance results in larger temperature gradients between irradiated and non-irradiated surfaces. Moreover, such a gradient

    1996-01-01

    This study aimed to evaluate the interest of a 1.9 micrometer diode laser for corneal wound suture. Six adult albino rabbits were anesthetized. A 7 mm corneal incision was practiced on the right eye. For 3 animals (laser plus stitch) the incision was surgically sutured with 2 stitches of a nylon monofilament and laser impacts were performed between the stitches. For 3 animals (laser only) juxtaposed lasers impacts were realized to suture the wound. After the procedure the animals were examined daily for signs of inflammation, infection and for healing of the corneal wound. Material was obtained for histological examination 1 month after the procedure. Approximation of the edges of the would was successfully obtained in the (laser plus stitch) group. In the (laser only) group this approximation remained troublesome. After the procedure, one cornea of the (laser only) group disclosed a little leakage during 2 days. Histological examination assessed the welding of the corneal wound in the two groups provided structural modifications and some inflammatory signs. Corneal welding using a 1.9 micrometer diode laser is possible either with laser and stitch or with laser only. The approximation of the edges of the wound with additional stitches is an evident drawback. The use of additional stitches should be avoided to keep the theoretical advantages of corneal would suture using laser welding.

    Neste trabalho analisamos o efeito do achatamento do corpo principal nos pontos de equilíbrio lagrangianos e na configuração de órbitas girino-ferradura. Enfatizamos os sistemas coorbitais de satélites de Saturno, pois se encontram em relativa proximidade com o planeta, em que o efeito do achatamento se torna mais evidente. O estudo é dividido em três etapas independentes. Na primeira fase analisamos as equações de movimento do problema restrito de três corpos considerando o efeito do achatamento, e através do balanceamento de forças buscamos a nova configuração dos pontos de equilíbrio lagrangianos. Concluímos, nesta etapa, que os pontos de equilíbrio estáveis apresentam um pequeno deslocamento definido pelo parâmetro de achatamento, não podendo ser mais representados por triângulos eqüiláteros. Aplicamos este resultado aos satélites coorbitais de Tetis e Dione, encontrando as posições de equilíbrio levemente deslocadas em relação ao caso sem achatamento. Na segunda fase visamos o sistema Saturno-Jano-Epimeteu, que por se tratar de um sistema de massas comparáveis, optamos por desenvolver as equações de Yoder et al (Icarus 53, pág 431-443, 1983), que permitem determinar os pontos de equilíbrio e a amplitude de oscilação angular das órbitas girino-ferradura para o problema não-restrito de três corpos, porém, no nosso estudo consideramos o efeito do achatamento do corpo principal nestas equações. Encontramos que a distância angular entre satélites, quando em posição de equilíbrio estável, diminui quanto maior for o parâmetro de achatamento do corpo principal. Além disso, a órbita de transição girino-ferradura possui largura angular menor em relação ao caso sem achatamento. Por fim, realizamos integrações numéricas para os casos reais de coorbitais de Saturno comparando com os resultados analíticos. Nestas integrações simulamos diversas órbitas girino-ferradura com diferentes parâmetros de achatamento, utilizando condições iniciais corrigidas para a presença do achatamento.

  19. Qual o Papel da Escola e da Mídia na Obtenção dos Conhecimentos Astronômicos?

    É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeiçoar a divulgação e o ensino não formal de Astronomia através da mídia aliando a adequação do conteúdo à expectativa das pessoas. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros tem introduzido Astronomia desde a pré-escola até o Ensino Médio. Num estudo realizado com 1180 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um formulário contendo questões que abordavam conhecimentos básicos em Astronomia, como foram adquiridos tais conhecimentos e à infra-estrutura da escola. Para 66,1% dos entrevistados o professor já fez alguma apresentação a respeito de Astronomia. O presente estudo revelou também que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 18,4% através da televisão e 27,1% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, livros didáticos, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio no meio em que os alunos obtiveram seus conhecimentos astronômicos, a mídia busca não somente sua difusão, mas a disponibilização desse conhecimento de maneira correta, que às vezes, não é atingido, apresentando conceitos sem fundamentação e incorretos. Por outro lado, no dia-a-dia escolar, é comum encontrar professores que vêm para as aulas com concepções prévias, que podem diferir substancialmente das idéias a serem ensinadas, dificultando o aprendizado de futuros conceitos científicos. Uma avaliação criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poderá proporcionar uma melhor compreensão sobre as concepções alternativas, presentes no ensino de Astronomia.
