Um estudo espectrofotométrico da variável cataclísmica V3885 Sgr  

NASA Astrophysics Data System (ADS)

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.

Estudo e aplicação do código de desembaraçamento espectral - Korel - em sistemas triplos  

NASA Astrophysics Data System (ADS)

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.

Estudo comparativo entre estrelas centrais de nebulosas planetárias deficientes em hidrogênio  

NASA Astrophysics Data System (ADS)

Apresentamos neste trabalho o resultado de um estudo das principais características espectrais das estrelas centrais de nebulosas planetárias (ECNP) deficientes em hidrogênio. A origem e a evolução dessas estrelas ainda constitui um problema em aberto na evolução estelar. Geralmente esses objetos são divididos em [WCE], [WCL] e [WELS]. Os tipos [WCE] e [WCL] apresentam um espectro típico de uma estrela Wolf-Rayet carbonada de população I e as [WELS] apresentam linhas fracas de carbono e oxigênio em emissão. Existem evidências que apontam a seguinte sequência evolutiva : [WCL] = > [WCE] = > [WELS] = > PG 1159 (pré anã-branca). No entanto, tal cenário apresenta falhas como por exemplo a falta de ECNP entre os tipos [WCL] e [WCE]. Baseados em uma amostra de 24 objetos obtida no telescópio de 1.52m em La Silla, Chile (acordo ESO/ON), ao longo do ano 2000, apresentamos os resultados da comparação das larguras equivalentes de diversas linhas relevantes entre os tipos [WCL], [WCE] e [WELS]. Verificamos que nossos dados estão de acordo com a sequência evolutiva. Baseado nas linhas de C IV, conseguimos dividir pela primeira vez as [WELS] em dois grupos principais. Além disso, os dados reforçam a afirmação de que as [WCE] são as estrelas que possuem a maior temperatura entre as ECNP deficientes em hidrogênio. Discutimos ainda, a escassez de dados disponíveis na literatura e a necessidade da obtenção de parametros físicos para estes objetos.

OV-Wav: um novo pacote para análise multiescalar em astronomia  

NASA Astrophysics Data System (ADS)

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.

BUDDA (Bulge/Disk Decomposition Analysis) - um novo programa para análise estrutural de galáxias  

NASA Astrophysics Data System (ADS)

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

Estudo de não gaussianidade nas anisotropias da RCF medidas Wmap  

NASA Astrophysics Data System (ADS)

A investigação do campo de flutuações da Radiação Cósmica de Fundo (RCF) pode oferecer um importante teste para os modelos cosmológicos que descrevem a origem e a evolução das flutuações primordiais. De um lado, apresenta-se o modelo inflacionário que prevê um espectro de flutuações adiabáticas distribuídas segundo uma gaussiana e, de outro, os modelos de defeitos topológicos (dentre outros) que descrevem um mecanismo para a geração de flutuações de isocurvatura que obedecem a uma distribuição não gaussiana. Este trabalho tem como objetivo caracterizar traços do modelo não gaussiano de campo misto (entre flutuações adiabáticas e de isocurvatura) nos mapas do Wilkinson Microwave Anisotropy Probe (WMAP). Simulações das anisotropias da RCF no contexto de mistura indicam traços marcantes na distribuição das flutuações de temperatura, mesmo quando consideradas pequenas contribuições do campo de isocurvatura (da ordem de 0.001). O efeito da mistura entre os campos resulta na transferência de potência de flutuações em escalas angulares intermediárias para flutuações em pequenas escalas angulares. Este efeito pode ser caracterizado pela relação entre as amplitudes dos primeiros picos acústicos no espectro de potência da RCF. Neste trabalho, investigamos a contribuição do campo de isocurvatura, no contexto de mistura, sobre as observações recentes da RCF realizadas pelo WMAP. As previsões do modelo de campo misto, uma vez confrontadas com as observações em pequenas escalas angulares, podem ajudar a revelar a natureza das flutuações primordiais.

BLAST sources at 250, 350 and 500um (Devlin+, 2009)  

NASA Astrophysics Data System (ADS)

Submillimetre surveys during the past decade have discovered a population of luminous, high-redshift, dusty starburst galaxies. In the redshift range 1 less than or equal to z less than or equal to 4, these massive submillimetre galaxies go through a phase characterized by optically obscured star formation at rates several hundred times that in the local Universe. Half of the starlight from this highly energetic process is absorbed and thermally re-radiated by clouds of dust at temperatures near 30K with spectral energy distributions peaking at 100um in the rest frame. At 1 less than or equal to z less than or equal to 4, the peak is redshifted to wavelengths between 200 and 500um. The cumulative effect of these galaxies is to yield extragalactic optical and far-infrared backgrounds with approximately equal energy densities. Since the initial detection of the far-infrared background (FIRB), higher-resolution experiments have sought to decompose this integrated radiation into the contributions from individual galaxies. Here we report the results of an extragalactic survey at 250, 350 and 500um. Combining our results at 500 mum with those at 24um, we determine that all of the FIRB comes from individual galaxies, with galaxies at z greater than or equal to 1.2 accounting for 70% of it. As expected, at the longest wavelengths the signal is dominated by ultraluminous galaxies at z>1. (3 data files).

XMM survey of 12um selected galaxies (Brightman+, 2011)  

NASA Astrophysics Data System (ADS)

We present an X-ray spectral analysis of 126 galaxies of the 12um galaxy sample (Rush et al. 1993, Cat. VII/157). By studying this sample at X-ray wavelengths, we aim to determine the intrinsic power, continuum shape and obscuration level in these sources. We improve upon previous works by the use of superior data in the form of higher signal-to-noise ratio spectra, finer spectral resolution and a broader bandpass from XMM-Newton. We pay particular attention to Compton thick active galactic nucleus (AGN) with the help of new spectral fitting models that we have produced, which are based on Monte Carlo simulations of X-ray radiative transfer, using both a spherical and torus geometry, and taking into account Compton scattering and iron fluorescence.

Genotyping of 73 UM-SCC head and neck squamous cell carcinoma cell lines  

PubMed Central

Background We established multiple UM-SCC (University of Michigan Squamous Cell Carcinoma) cell lines. With time, these have been distributed to other labs all over the world. Recent scientific discussions have noted the need to confirm the origin and identity of cell lines in grant proposals and journal articles. We genotyped the UM-SCC cell lines in our collection to confirm their unique identity. Design Early passage UM-SCC cell lines were genotyped and photographed. Results Thus far, 73 unique head and neck UM-SCC cell lines (from 65 donors including 21 lines from 17 females) were genotyped. In 7 cases separate cell lines were established from the same donor. Conclusions These results will be posted on the U of M Head and Neck SPORE Tissue Core website for other investigators to confirm that the UM-SCC cells used in their laboratories have the correct features. Publications using UM-SCC cell lines should confirm the genotype.

The UM/CTIO Magellanic Cloud Emission-line Survey  

NASA Astrophysics Data System (ADS)

The interstellar medium (ISM) is no longer thought to be a quiescent distribution of gas, but rather a dynamic and complex interaction of the ambient gas and dust with stellar winds, HII regions, planetary nebulae (PNe), supernovae (SNe), supernova remnants (SNRs), superbubbles, and gigantic supershells. Nowhere is this more apparent than in images of the ionized gas in the Magellanic Clouds. Their relative proximity and low extinction make them the ideal laboratories in which to study the ionized component of the ISM, its constituents, its energetics, and its interaction with the underlying stellar populations. We have begun an optical emission-line survey of these two nearby galaxies, the UM/CTIO Magellanic Cloud Emission-line Survey (MCELS). Together with parallel surveys at other wavelengths, it will provide the foundation upon which to build a deeper understanding of the ISM in the Clouds (and other galaxies), from small scales (~ 1 pc) to global scales. Taking advantage of the wide field of view of the UM/CTIO Curtis Schmidt telescope coupled to the sensitivity and large area of a STIS 2K CCD, we will obtain H alpha, [S II], and [O III] images of the central 8x8 degrees of the Large Magellanic Cloud and of the central 3.5 x 4.5 degrees of the Small Magellanic Cloud, covering most of the gaseous extent of both Clouds with a resolution of ~ 4". Survey observations began in November 1995, and we have completed approximately 75% of the imaging as of the end of the 1997/1998 Cloud season. The survey will provide definitive samples of wind-blown bubbles, PNe, and SNRs, as well as detailed and calibrated emission-line observations of HII regions, superbubbles, and supergiant shells. We will discuss the scientific objectives of the survey, describe the survey parameters and strategies, and present some of the recent results from analysis of preliminary datasets. Furthermore, we will describe the plans for making the digital Emission-line Atlas of the Magellanic Clouds publically available, providing a rich, homogeneous dataset to serve as the groundwork for further investigations into all aspects of the ISM, well beyond the scope of our own work.

Confusion-Limited 70um Imaging of the GOODS Hubble Deep Field North  

NASA Astrophysics Data System (ADS)

We propose confusion-limited MIPS 70um imaging of the GOODS Hubble Deep Field North (HDF-N). The goal of these observations is to determine the infrared properties of the highest redshift sources detectable by the MIPS on Spitzer. In particular, we will derive source counts at the faintest possible depths and measure the infrared luminosity function out to z~1.5. We will also measure the 70um/24um flux density ratios to constrain what fraction of the infrared background arises from infrared-cool, starburst dominated luminous infrared galaxies versus infrared-warm AGN. Ultraluminous infrared galaxies contribute significantly to the total star-formation at high-redshift and are expected to be detected at flux levels near the confusion limit of the MIPS-70 band. Due to the much lower than expected in-flight performance of the 70um detectors and the loss of over half the array due to cabling issues, the planned observations of the HDF-N by the MIPS-GTO team will not reach the confusion level or the depth required to detect high-redshift sources at 70um. We propose to observe the HDF-N field to the ultimate depth at 70um. These observations are motivated by the GOODS philosophy of obtaining the deepest possible images from NASA's Great Observatories (HST, Chandra, and Spitzer) and will greatly build upon our knowledge of the high-redshift universe by probing the far-infrared band to unprecedented depths.

Estudo de perturbações orbitais de satélites artificiais, considerando ressonância, através de transformações canônicas  

NASA Astrophysics Data System (ADS)

Aplicações recentes de satélites artificiais, principalmente aquelas com finalidades geodinâmicas ou altimétricas, requerem órbitas determinadas com bastante precisão. Em particular os satélites do sistema GPS, que têm sido envolvidos direta ou indiretamente em tais problemas, necessitam de ter suas órbitas muito bem conhecidas. As órbitas dos satélites GPS tem uma peculiaridade: o período orbital está em comensurabilidade 2: 1, aproximada, com o período de rotação da Terra. A existência de ressonâncias faz com que métodos usuais de teoria de perturbações não possam ser usados para se estudar órbitas com esta característica. No presente trabalho são apresentados dois processos para se estudar tal problema. Para tanto o sistema dinâmico que descreve o movimento orbital de satélites artificiais, perturbado por forças que derivem ou não de um potencial, incluindo ressonância, é inicialmente colocado em forma canônica estendida. Um dos processos apresentado é baseado na teoria de Lie-Hori e o outro em uma seqüência de transformações canônicas. Perturbações devidas ao geopotencial, ao arrasto atmosférico, à pressão de radiação solar direta (incluindo o efeito da sobra) e à ressonâncias do movimento orbital com o movimento de rotação da Terra são consideradas. Neste trabalho, sucintamente, os dois processos originais desenvolvidos em colaboração com o autor são apresentados. Simulações são feitas mostrando o efeito da ressonâncias 2: 1 na evolução temporal de elementos orbitais de satélites artificiais. Exemplos são exibidos para diversas órbitas considerando-se diferentes excentricidades e inclinações, incluindo às do tipo GPS.

Um Projeto de Intervenção nos Espaços de Exposições do Planetário do Parque do Ibirapuera  

NASA Astrophysics Data System (ADS)

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.

Isoalantolactone Inhibits UM-SCC-10A Cell Growth via Cell Cycle Arrest and Apoptosis Induction  

PubMed Central

Isoalantolactone is a sesquiterpene lactone compound isolated from the roots of Inula helenium L. Previous studies have demonstrated that isoalantolactone possesses antifungal, anti-bacterial, anti-helminthic and anti-proliferative properties in a variety of cells, but there are no studies concerning its effects on head and neck squamous cell carcinoma (HNSCC). In the present study, an MTT assay demonstrated that isoalantolactone has anti-proliferative activity against the HNSCC cell line (UM-SCC-10A). Immunostaining identified that this compound induced UM-SCC-10A cell apoptosis but not necrosis. To explain the molecular mechanisms underlying its effects, flow cytometry and western blot analysis showed that the apoptosis was associated with cell cycle arrest during the G1 phase, up-regulation of p53 and p21, and down-regulation of cyclin D. Furthermore, our results revealed that induction of apoptosis through a mitochondrial pathway led to up-regulation of pro-apoptotic protein expression (Bax), down-regulation of anti-apoptotic protein expression (Bcl-2), mitochondrial release of cytochrome c (Cyto c), reduction of mitochondrial membrane potential (MMP) and activation of caspase-3 (Casp-3). Involvement of the caspase apoptosis pathway was confirmed using caspase inhibitor Z-VAD-FMK pretreatment. Together, our findings suggest that isoalantolactone induced caspase-dependent apoptosis via a mitochondrial pathway and was associated with cell cycle arrest in the G1 phase in UM-SCC-10A cells. Therefore, isoalantolactone may become a potential drug for treating HNSCC.

A questionnaire-based (UM-PDHQ) study of hallucinations in Parkinson's disease  

PubMed Central

Background Hallucinations occur in 20–40% of PD patients and have been associated with unfavorable clinical outcomes (i.e., nursing home placement, increased mortality). Hallucinations, like other non-motor features of PD, are not well recognized in routine primary/secondary clinical practice. So far, there has been no instrument for uniform characterization of hallucinations in PD. To this end, we developed the University of Miami Parkinson's disease Hallucinations Questionnaire (UM-PDHQ) that allows comprehensive assessment of hallucinations in clinical or research settings. Methods The UM-PDHQ is composed of 6 quantitative and 14 qualitative items. For our study PD patients of all ages and in all stages of the disease were recruited over an 18-month period. The UPDRS, MMSE, and Beck Depression and Anxiety Inventories were used for comparisons. Results and Discussion Seventy consecutive PD patients were included in the analyses. Thirty-one (44.3%) were classified as hallucinators and 39 as non-hallucinators. No significant group differences were observed in terms of demographics, disease characteristics, stage, education, depressive/anxiety scores or cognitive functioning (MMSE) between hallucinators and non-hallucinators. Single mode hallucinations were reported in 20/31 (visual/14, auditory/4, olfactory/2) whereas multiple modalities were reported in 11/31 patients. The most common hallucinatory experience was a whole person followed by small animals, insects and reptiles. Conclusion Using the UM-PDHQ, we were able to define the key characteristics of hallucinations in PD in our cohort. Future directions include the validation of the quantitative part of the questionnaire than will serve as a rating scale for severity of hallucinations.

Uma Visão do Universo Segundo um Grupo de Alunos do Ensino Médio de São Paulo  

NASA Astrophysics Data System (ADS)

A astronomia, embora seja uma ciência popular, com inúmeras descobertas de interesse público, ainda é apresentada desconsiderando-se os aspectos históricos e científicos relacionados ao seu desenvolvimento, sendo geralmente veiculada nos meios de comunicação de maneira pouco esclarecedora e não raro com imprecisões. Neste trabalho analisou-se a concepção de um grupo de estudantes de Ensino Médio sobre conceitos de astronomia, visando identificar sua visão de mundo a respeito do Universo, envolvendo idéias sobre espaço e tempo. Para issso, foi aplicado um questionário em três escolas da grande São Paulo em um espaço amostral de 270 alunos. Constatou-se que, embora o ensino de astronomia esteja previsto nos PCNEM, os resultados obtidos na pesquisa mostram que há grande deficiência no conhecimento dos temas investigados. Nesse sentido, verificou-se que apenas 20% dos alunos eram capazes de relacionar a sucessão das semanas com as fases da lua, enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra. Por outro lado, somente 23% dos alunos tinham noções das distâncias entre os objetos celestes próximos da Terra e 56% conseguiram relacionar o Big Bang com a origem do Universo. Finalmente, constatou-se que 37% reconheciam o ano-luz como uma unidade de distância e 60% reconheciam o Sol como sendo uma estrela. Apesar de 60% dos alunos indicarem que a escola é a principal fonte para aquisição dos conhecimentos de astronomia, conclui-se que seus conceitos nessa área ainda são inadequados, havendo necessidade de ampliação e aprimoramento da abordagem desses conteúdos nos ambientes escolares.

Um supressor de fundo térmico para a câmara infravermelha CamIV  

NASA Astrophysics Data System (ADS)

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.

Origin and characteristics of yardangs in the Um Al-Rimam depressions (N Kuwait)  

NASA Astrophysics Data System (ADS)

Although Arabia hosts one of the largest deserts in the world, studies regarding aeolian erosional features in general and yardangs in particular are rare. The principal aim of this study is to delineate and investigate the various forms of yardangs in the Um Al-Rimam depressions in the northern part of Kuwait. The study area consists of two main depressions connected by neck area made up of continental sediments. Both depressions are surrounded by a dissected escarpment and their floors host muddy playas. On lithological bases, three main types of yardang have been identified: 7 yardangs are sculptured in sandstones of Lower Fars Formation (Lower to Middle Miocene), 23 are carved in calcretic rocks of Ghar Formation (Oligocene to Lower Miocene), and 11 yardangs are developed in Quaternary sediments. Their mean orientation NW (297°) coincides with the prevailing direction of the strong local northwesterly wind called the shamal. The average length/width ratio is 1.5:1. The wide geographic distribution of yardangs around the margins of the northern depression is due to sand blasting. This is explained by the annual sand accumulation measured in the study area where the northern depression shows 143 times higher accumulation than the southern depression, the neck area and the platform above the depressions. Also, the field measurements for annual erosional rates show that the sides of the yardangs are more affected by erosion compared to their middle parts. Remarkably slight mineralogical variations were detected within the surface sediments of Um Al-Rimam depressions and the Quaternary muddy yardangs which indicate a common origin. The age of yardangs is unknown but annual erosional rates on a small Quaternary muddy yardang suggest that they range in age between 44 and 1500 years depending on yardang size. It is believed, as indicated from field observation and interpretation of aerial photos, that the majority of yardangs are pre-existing bedrock forms. These forms were developed by paleo-surface hydrological processes which were modified by wind action in latter phase.

Determinação da massa de júpiter a partir das órbitas de seus satélites: um experimento didático  

NASA Astrophysics Data System (ADS)

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

Design of a Monolithic Active Pixel Sensor in ST 0.13UM Technology  

NASA Astrophysics Data System (ADS)

This paper presents the architecture of a new Monolithic Active Pixel Sensor chip designed in ST Microelectronics 0.13um CMOS technology at the Roma Tre University INFN Section. The two goals of the chip are: technology characterization and test of data sparsification architecture, implemented to fulfil requirements of the future high energy physics experiments. In the intended applications the commonly used 'off-line' and 'off-chip' signal processing is not possible due to a huge bandwidth needed to read out all pixels at a satisfactory speed. The authors propose a new approach for the on-line data sparsification which consists in implementation of the full on-pixel signal processing. The difficulties that had to be overcame are: limited on-pixel silicon area for fitting all the necessary electronic circuitry, forced use of only NMOS transistors in the sensing area, current and threshold mismatch typical for CMOS submicron technologies. Finally special care had to be taken to avoid crosstalk from digital to analog signals.

Flux and color variations of the doubly imaged quasar UM673?  

NASA Astrophysics Data System (ADS)

Aims: With the aim of characterizing the flux and color variations of the multiple components of the gravitationally lensed quasar UM673 as a function of time, we have performed multiepoch and multiband photometric observations with the Danish telescope at the La Silla Observatory. Methods: The observations were carried out in the VRi spectral bands during four seasons (2008-2011). We reduced the data using the point spread function photometric technique as well as aperture photometry. Results: Our results show for the brightest lensed component some significant decrease in flux between the first two seasons (+ 0.09/+ 0.11/+ 0.05 mag) and a subsequent increase during the following ones (- 0.11/- 0.11/- 0.10 mag) in the V/R/i spectral bands, respectively. Comparing our results with previous studies, we find smaller color variations between these seasons as compared with previous ones. We also separate the contribution of the lensing galaxy from that of the fainter and close lensed component. Based on data collected by MiNDSTEp with the Danish 1.54 m telescope at the ESO La Silla ObservatoryLight curves are only available in electronic from at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/551/A104

UM-SCC-104: a new human papillomavirus-16 containing head and neck squamous cell carcinoma cell line  

PubMed Central

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.

Spectral reflectance of carbonate minerals in the visible and near infrared (0.35-2.55 um): Anhydrous carbonate minerals  

NASA Astrophysics Data System (ADS)

Reflectance spectroscopy in the visible and near infrared (0.35-2.55 um) offers a rapid, inexpensive, nondestructive technique for determining the mineralogy and gaining information on the minor element chemistry of carbonate minerals and rocks. Spectra of all commonly occurring anhydrous end-member carbonate minerals contain seven strong absorption bands at wavelengths >1.6 um due to vibrations of the carbonate radical. Positions, widths, and spacing between carbonate bands are diagnostic of mineralogy. Differences in positions of carbonate bands between spectra of different minerals are primarily due to differences in mass of the major cation, with cation electronegativity playing a secondary role. Spectra of calcite group minerals may contain absorption features due to transition metal cations such as Fe and Mn, which can also aid in mineral identification. Spectra confirm the occurrence of both cations in the divalent state. Fe2+ produces a broad feature near 1.1 um whose position and degree of doubling are related to the size and degree of distortion of the octahedral site, as predicted by crystal field theory. Mn2+ and Fe2+ produce very strong absorption bands in the minerals for which they are the major cation (rhodochrosite and siderite, respectively), making it easy to distinguish these from other carbonate minerals, even when presence of water bands may make it difficult to determine accurately carbonate band positions.

NE VIII lambda 774 and time variable associated absorption in the QSO UM 675  

NASA Astrophysics Data System (ADS)

We discuss measurements of Ne VIII lambda 774 absorption and the time variability of other lines in the za approximately equal ze absorption system of the ze = 2.15 QSO UM 675 (0150-203). The C IV lambda 1549 and N V 1240 doublets at za = 2.1340 (shifted approximately 1500 km/s from ze strengthened by a factor of approximately 3 between observations by Sargent, Boksenberg and Steidel (1981 November) and our earliest measurements (1990 November and December). We have no information on changes in other za approximately equal ze absorption lines. Continued monitoring since 1990 November shows no clear changes in any of the absorptions between approximately 1100 and 1640 A rest. The short timescale of the variability (less than or approximately equal to 2.9 yr rest) strongly suggests that the clouds are dense, compact, close to the QSO, and photoionized by the QSO continuum. If the line variability is caused by changes in the ionization, the timescale requires densities greater than approximately 4000/cu cm. Photoionization calculations place the absorbing clouds within approximately 200 pc of the continuum source. The full range of line ionizations (from Ne VIII lambda 774 to C III lambda 977) in optically thin gas (no Lyman limit) implies that the absorbing regions span a factor of more than approximately 10 in distance or approximately 100 in density. Across these regions, the total hydrogen (H I + H II) column ranges from a few times 1018/sq cm in the low-ionization gas to approximately 1020/sq cm where the Ne VIII doublet forms. The metallicity is roughly solar or higher, with nitrogen possibly more enhanced by factors of a few. The clouds might contribute significant line emission if they nearly envelop the QSO. The presence of highly ionized Ne VIII lambda 774 absorption near the QSO supports recent studies that link za approximately equal to ze systems with X-ray 'wamr absorbers. We show that the Ne VIII absorbing gas would itself produce measurable warm absorption -- characterized by bound-free O VII or O VIII edegs near 0.8 keV -- if the column densities were NH greater than or approximately equal to 1021/sq cm (for solar abundances).

Microwave window breakdown experiments and simulations on the UM/L-3 relativistic magnetron  

NASA Astrophysics Data System (ADS)

Experiments have been performed on the UM/L-3 (6-vane, L-band) relativistic magnetron to test a new microwave window configuration designed to limit vacuum side breakdown. In the baseline case, acrylic microwave windows were mounted between three of the waveguide coupling cavities in the anode block vacuum housing and the output waveguides. Each of the six 3 cm deep coupling cavities is separated from its corresponding anode cavity by a 1.75 cm wide aperture. In the baseline case, vacuum side window breakdown was observed to initiate at single waveguide output powers close to 20 MW. In the new window configuration, three Air Force Research Laboratory-designed, vacuum-rated directional coupler waveguide segments were mounted between the coupling cavities and the microwave windows. The inclusion of the vacuum side power couplers moved the microwave windows an additional 30 cm away from the anode apertures. Additionally, the Lucite microwave windows were replaced with polycarbonate windows and the microwave window mounts were redesigned to better maintain waveguide continuity in the region around the microwave windows. No vacuum side window breakdown was observed in the new window configuration at single waveguide output powers of 120+MW (a factor of 3 increase in measured microwave pulse duration and factor of 3 increase in measured peak power over the baseline case). Simulations were performed to investigate likely causes for the window breakdown in the original configuration. Results from these simulations have shown that in the original configuration, at typical operating voltage and magnetic field ranges, electrons emitted from the anode block microwave apertures strike the windows with a mean kinetic energy of 33 keV with a standard deviation of 14 keV. Calculations performed using electron impact angle and energy data predict a first generation secondary electron yield of 65% of the primary electron population. The effects of the primary aperture electron impacts, combined with multiplication of the secondary populations, were determined to be the likely causes of the poor microwave window performance in the original configuration.

On the Compact H II Galaxy UM 408 as Seen by GMOS-IFU: Physical Conditions  

NASA Astrophysics Data System (ADS)

We present Integral Field Unit GMOS-IFU data of the compact H II galaxy UM 408, obtained at the Gemini South telescope, in order to derive the spatial distribution of emission lines and line ratios, kinematics, plasma parameters, and oxygen abundances as well the integrated properties over an area of 3''×4farcs4 equivalent with ~750 pc × 1100 pc located in the central part of the galaxy. The starburst in this area is resolved into two giant regions of about 1farcs5 and 1'' (~375 and ~250 pc) diameter, respectively and separated 1.5-2'' (~500 pc). The extinction distribution concentrate its highest values close but not coincident with the maxima of H? emission around each one of the detected regions. This indicates that the dust has been displaced from the exciting clusters by the action of their stellar winds. The ages of these two regions, estimated using H? equivalent widths, suggest that they are coeval events of ~5 Myr with stellar masses of ~104 M sun. We have also used [O III]/H? and [S II]/H? ratio maps to explore the excitation mechanisms in this galaxy. Comparing the data points with theoretical diagnostic models, we found that all of them are consistent with excitation by photoionization by massive stars. The H? emission line was used to measure the radial velocity and velocity dispersion. The heliocentric radial velocity shows an apparent systemic motion where the east part of the galaxy is blueshifted, while the west part is redshifted, with a relative motion of ~10 km s-1. The velocity dispersion map shows supersonic values typical for extragalactic H II regions. We derived an integrated oxygen abundance of 12+log(O/H) = 7.87 summing over all spaxels in our field of view. An average value of 12+log(O/H) = 7.77 and a difference of ?(O/H) = 0.47 between the minimum and maximum values (7.58 ± 0.06-8.05 ± 0.04) were found, considering all data points where the oxygen abundance was measured. The spatial distribution of oxygen abundance does not show any significant gradient across the galaxy. On the other hand, the bulk of data points are lying in a region of ±2? dispersion (with ? = 0.1 dex) around the average value, confirming that this compact H II galaxy, like other previously studied dwarf irregular galaxies, is chemically homogeneous. Therefore, the new metals processed and injected by the current star formation episode are possibly not observed and reside in the hot gas phase, whereas the metals from previous events are well mixed and homogeneously distributed through the whole extent of the galaxy.

Implementation of the Fast-JX Photolysis scheme into the UKCA component of the MetUM chemistry climate model  

NASA Astrophysics Data System (ADS)

Atmospheric chemistry is driven by photolytic reactions, making their modelling a crucial component of atmospheric models. We describe the implementation and validation of Fast-JX, a state of the art model of interactive photolysis, into the MetUM chemistry climate model. This allows for interactive photolysis frequencies to be calculated in the troposphere and augments the calculation of the frequencies in the stratosphere by accounting for clouds and aerosols in addition to ozone. In order to demonstrate the effectiveness of this new photolysis scheme we employ new methods of validating the model, including techniques for sampling the model to compare to flight track and satellite data.

The U. S. Geological Survey, Digital Spectral Library: Version 1 (0.2 to 3.0um)  

USGS Publications Warehouse

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.

Silver and silver-bearing minerals at the Um Samiuki volcanogenic massive sulphide deposit, Eastern Desert, Egypt  

NASA Astrophysics Data System (ADS)

The Um Samiuki Zn Cu Pb Ag mineralisation, south Eastern Desert, Egypt is hosted by felsic volcanic rocks which form part of the 712-Ma-old, east-west-trending Shadli Volcanic Belt. Two major occurrences of massive sulphides are present at the top of rhyolitic breccia in the Western and Eastern mine areas. In each occurrence, a bornite-bearing zone is overlain by a pyrite-chalcopyrite-bearing zone and underlain by a disseminated, Cu-depleted zone. In the massive sulphide ore, sphalerite, chalcopyrite, pyrite, galena, bornite and tetrahedrite tennantite are major minerals, whereas arsenopyrite, pyrrhotite, molybdenite and magnetite are accessory phases. Covellite and digenite are common secondary minerals. Bornite, tetrahedrite tennantite and covellite contain high amounts of silver (averages of 1.97, 1.39 and 1.82 wt% respectively). Based on mineralogical balance calculations, bornite and covellite accommodate 80% of silver in the Um Samiuki deposit. Ag was incorporated in the crystal structure of the early-crystallised copper sulphides and sulphosalts and silver minerals. The temperature, sequential precipitation of the fluids and the structure of the crystallising phases control the distribution of silver. Post-depositional deformation and metamorphic processes caused liberation, remobilisation and redeposition of silver within the massive sulphides.

A Visão do Universo Segundo a Concepção de um Grupo de Alunos do Ensino Médio de São Paulo  

NASA Astrophysics Data System (ADS)

Nesse trabalho foi identificada por meio de um questionário a visão de mundo sobre o Universo espaço e tempo entre 270 estudantes de Ensino Médio de três escolas de São Paulo. Constatou-se pouco conhecimento dos temas investigados sendo que apenas 20% dos alunos relacionaram as semanas com as fases da lua enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra e 23% tinham noções das distâncias entre objetos celestes próximos da Terra. Enquanto 56% conseguiram relacionar o Big Bang com a origem do Universo verificou-se que 37% reconheciam ano-luz como unidade de distância e 60% reconheciam o Sol como uma estrela. Apesar de 60% dos alunos indicarem a escola como principal fonte dos conhecimentos de astronomia seus conceitos ainda são inadequados havendo necessidade de aprimoramento da abordagem desses conteúdos pois apesar de popular a astronomia é veiculada de maneira pouco esclarecedora e com imprecissões.

The yfhQ gene of Escherichia coli encodes a tRNA:Cm32/Um32 methyltransferase  

PubMed Central

Background Naturally occurring tRNAs contain numerous modified nucleosides. They are formed by enzymatic modification of the primary transcripts during the complex RNA maturation process. In model organisms Escherichia coli and Saccharomyces cerevisiae most enzymes involved in this process have been identified. Interestingly, it was found that tRNA methylation, one of the most common modifications, can be introduced by S-adenosyl-L-methionine (AdoMet)-dependent methyltransferases (MTases) that belong to two structurally and phylogenetically unrelated protein superfamilies: RFM and SPOUT. Results As a part of a large-scale project aiming at characterization of a complete set of RNA modification enzymes of model organisms, we have studied the Escherichia coli proteins YibK, LasT, YfhQ, and YbeA for their ability to introduce the last unassigned methylations of ribose at positions 32 and 34 of the tRNA anticodon loop. We found that YfhQ catalyzes the AdoMet-dependent formation of Cm32 or Um32 in tRNASer1 and tRNAGln2 and that an E. coli strain with a disrupted yfhQ gene lacks the tRNA:Cm32/Um32 methyltransferase activity. Thus, we propose to rename YfhQ as TrMet(Xm32) according to the recently proposed, uniform nomenclature for all RNA modification enzymes, or TrmJ, according to the traditional nomenclature for bacterial tRNA MTases. Conclusion Our results reveal that methylation at position 32 is carried out by completely unrelated TrMet(Xm32) enzymes in eukaryota and prokaryota (RFM superfamily member Trm7 and SPOUT superfamily member TrmJ, respectively), mirroring the scenario observed in the case of the m1G37 modification (introduced by the RFM member Trm5 in eukaryota and archaea, and by the SPOUT member TrmD in bacteria).

Geochemical and K Ar age constraints on the Late Neoproterozoic (?) gneisses at Um Tenassib area, north Eastern Desert, Egypt  

NASA Astrophysics Data System (ADS)

Wadi Um Tenassib metamorphic rocks consist mainly of biotite gneiss and biotite-hornblende gneiss with subordinate intercalations of amphibolite, migmatitic gneiss, and aplitic granite. Biotite-hornblende gneiss, biotite gneiss, and aplitic granite are geochemically characterized and their cooling ages are determined by using the K Ar method on biotite. The Um Tenassib gneisses (UTG) range in composition from quartz diorite/monzodiorite to granodiorite. They were derived from igneous rocks that pertain to calc alkaline and metaluminous to weakly peraluminous affinities and were generated in continental volcanic arc setting. REE patterns of the UTG are moderately fractionated (LaN/LuN = 5.9 7.5) relative to those of the aplitic granite (LaN/LuN = 33). The similarity in the geochemical characteristics and REE patterns of both gneiss types indicate their magmatic consanguinity. Amphiboles of the UTG biotite-hornblende gneisses are mainly hornblende, together with few paragasitic hornblende and edenite. Plagioclase composition is oligoclase to andesine (An21 46) in the biotite-hornblende gneiss, and oligoclase (An11 26) in the biotite gneiss. Mineral chemistry of amphibole and plagioclase indicate that the gneisses were metamorphosed under low- to medium-pressure of 2.6 6.4 kbar and at medium to high temperatures of 660 755 °C. The K Ar biotite cooling ages (seven samples) range from 585 ± 12 Ma to 598 ± 12 Ma for the UTG, except one biotite-hornblende gneiss sample gives age of 577 ± 11 Ma. These ages suggest a latest metamorphic cooling event at ca. 585 600 Ma time span, which is consistent with the proposed cooling ages of ˜600 Ma for the Elat metamorphic rocks [Cosca, M.A., Shimron, A., Caby, R., 1999. Late Precambrian metamorphism and cooling in the Arabian Nubian Shield: petrology and 40Ar/39Ar geochronology of metamorphic rocks of the Elat area (southern Israel). Precamb. Res. 98, 107 127]. It may indicate that the metamorphism of the UTG might have been contemporaneous with the suggested regional metamorphism at 620 ± 10 Ma for Sinai metamorphic rocks (Cosca et al., 1999) and/or the emplacement age at 614 Ma for the granodiorite in the study area [Stern, R.J., Hedge, C.E., 1985. Geochronological and isotopic constraints on the Late Precambrian crustal evolution in the Eastern Desert of Egypt. Am. J. Sci. 285, 97 127]. These ages also lie within the range of magmatic activity of the Younger Granites in the North Eastern Desert (575 600 Ma).

Effects of basic fibroblast growth factor on the differentiation, growth, and viability of a new human medulloblastoma cell line (UM-MB1).  

PubMed Central

We presently report the effects of human recombinant basic fibroblast growth factor (bFGF) on a newly established medulloblastoma cell line, UM-MB1. This predominantly adherent cell line has a mean doubling time of 39.3 hours and was found, by karyotypic analysis, to be near triploid. UM-MB1 consists of undifferentiated cells expressing markers of neuronal lineage such as the three neurofilament subunits as well as neuron-specific enolase, synaptophysin, and microtubule-associated proteins 1 and 5. In contrast, no immunoreactivity for glial fibrillary acidic protein was evident. When exposed to nanomolar amounts of bFGF, UM-MB1 cells began to extend neurite-like processes with arborizations and growth-cone-like structures. In addition, UM-MB1 cells treated with bFGF exhibited ultrastructural alterations that reflect their enhanced differentiation as well as the increased expression of at least one of the neurofilament subunits as evidenced both immunocytochemically and on Western blots. Furthermore, bFGF significantly decreased UM-MB1 cell growth as well as induced their death. UM-MB1 cells treated with bFGF for several days displayed DNA cleavage, nuclear shrinkage, and chromatin condensation while retaining their cytoplasmic and mitochondrial membrane integrity, all early indices of apoptosis. After this, cell death was evident with the concomitant appearance of the classical apoptotic bodies. By flow cytometry, bFGF was found to increase the proportion of cells in G1 before inducing their death by apoptosis. In conclusion, UM-MB1 cells can, when appropriately stimulated, be induced to differentiate along their neuronal lineage pathway. Their differentiation induced by bFGF, although incomplete, appears to promote or inhibit the expression of apoptotic effectors or suppressors in these cells, respectively, so to induce their death by an apoptotic-like mechanism.

Jets and Outflows from Young Stellar Objects in the Carina Nebula Observed in [Fe II] 1.64 um  

NASA Astrophysics Data System (ADS)

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.

InP-based monolithic integration of 1.55-um MQW laser diode and HBT driver circuit  

NASA Astrophysics Data System (ADS)

An improved fabrication process and related experiment results of an InP-based monolithic integrated transmitter OEIC with a 1.55 micrometers MQW laser diode (LD) and an InP/InGaAs heterojunction bipolar transistors (HBT) driver circuit are presented. The epitaxial structure of the laser and driver circuits were continuously grown on semi- insulating Fe-doped InP substrate by a metal-organic chemical vapor deposition system using a vertically integration. HCL, H3PO4/H2O2 and HBr/HNO3 solution system were involved as selective or nonelective wet chemical etching respectively for the epitaxies of InP, InGaAs and InGaPAs. Both a nearly-standard contact photolithography depending on a two-step exposure technique and an electrical connection related to smoothly wet chemical etching profile of InP and InGaP in the crystal direction of (01-1) were developed in the process. The laser diode with a 3-um-wide ridge waveguide forming by a double- groove process self-aligned to the metal contact of P-type region showed an average threshold current as low as about 10mA. The HBT with a 120-nm-thick base layer performed a DC current gain of about 60-70 and an emitter-collector breakdown voltage of up to 4-5V. A clear eye diagram of the monolithic transmitter under a pulsed operation with 622Mbit/s bitrate nonreturn-to-zero pseudorandom code was obtained.

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

NASA Astrophysics Data System (ADS)

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.

Modelling the 11.2 um Unidentified Infrared Band using Ethylene Oxide (c-C2H4O) and Cyclopropenylidene (c-C3H2)  

NASA Astrophysics Data System (ADS)

We suggest that small carbonaceous molecules (SCMs) may be the sources of the unidentified infrared bands (UIR) and the underlying continuum. We show that the IR spectroscopy of ethylene oxide (EO, c-C2H4O) and cyclopropenylidene (CP, c-C3H2) closely correlates with the major UIR bands at 3.3, 6.2, 7.7, 8.6, and 11.2 um, the often seen strong bands at 12.7 and 16.4 um, as well as many minor features. The differences in band locations and shapes between laboratory EO absorption spectra and astrophysical UIR emission spectra are attributed to vibrational anharmonicity, Fermi resonance splitting of nearly degenerate vibration levels, and rotational envelop narrowing due to the low temperatures in space. The excitation mechanism is absorption of UV radiation, primarily Ly-alpha, by SCMs. Photon trapping for this very optically thick transition enhances the absorption by several orders of magnitude. Our abundance analysis for NGC 7027 reveals that the SCM abundance, relative to H2, is 3E-9 which compares well to radio measurements of the CP abundance range of 1E-9 - 1E-7. Radio lines of CP have been seen in numerous astronomical objects, most displaying the UIR bands. EO is also seen, but in fewer objects, none displaying the UIR bands. We theorize that in UIR objects, EO is formed on, and primarily resides on, carbonaceous grains, precluding radio detection of rotational lines. We present a detailed spectral analysis of the 11.2 um UIR band and its associated continuum. An asymmetric top rotational model is used to fit the feature profiles observed from a variety of astrophysical objects. We show that the narrower 11.2 um feature can be fit based on EO or CP rotational constants at a temperature around 10 K and the broader continuum corresponds to 200 K. We suggest laboratory experiments, astronomical observations, and theoretical investigations to further evaluate the SCM mechanism.

Vínculos sobre um modelo de quartessência de Chaplygin usando observações do satélite chandra da fração de massa de gás em aglomerados de galáxias  

NASA Astrophysics Data System (ADS)

Observações de Supernovas do tipo Ia mostram que a expansão do Universo está acelerando. Segundo as equações de Einstein uma componente com pressão negativa (energia escura) é necessária para explicar a aceleração cósmica. Além da energia escura é usualmente admitido que no Universo há também uma matéria exótica com pressão zero, que é chamada de matéria escura. Essa componente possui um papel fundamental na formação de estruturas no Universo. Recentemente tem se explorado a possibilidade de que matéria e energia escura poderiam ser unificadas através de uma única componente, que tem sido denominada de quartessência. Um exemplo de fluido com essas características é o Gás de Chaplygin Generalizado, que possui uma equação de estado da forma p = -A/ra. Inicialmente consideramos o caso especial a = 1 (gás de Chaplygin) e vinculamos parâmetros do modelo utilizando observações em raios-X do satélite Chandra da fração de massa de gás em aglomerados de galáxias. Uma comparação dos vínculos obtidos com esse teste com outros testes, tais como supernovas e idade do Universo, mostra que esse teste é bastante restritivo. Exibiremos ainda resultados para o caso em que a curvatura é nula e o parâmetro a está compreendido no intervalo -1 < a 1.

Etching characteristics of organic low-k dielectrics in the helicon-wave plasma etcher for 0.15-um damascene architecture  

NASA Astrophysics Data System (ADS)

The comparative analysis of the dry etching of FLARE 2.0 and a- C:F, which represent two different depositions techniques of organic low-k polymers was investigated. In our damascene architecture, the etchings to player or hard-mask of both SIOF; SiO2 was studied. Especially, the SiOF providing lower dielectric constant than SIO2 would reduce entire effective dielectric constant. The etch rate and etching rate selectivity was optimized by changing content ratio between CHF3, N2 and O2. Furthermore, the bias power, RF power; and gas flows were changed to control the etch profile. The SEM result showed that the better etch profile can be obtained at higher bias power. There were some deviation between etching rate of blanket with the case of patterned wafer. The distribution density of the reactant etching gas in sub-um gap different from blanket surface of wafer was major dynamics. Due to this phenomena, the etching rate became nonlinear function of process time Tetch in the trenches/vias with smaller dimension.

Project UM-HAUL (UnManned Heavy pAyload Unloader and Lander): The design of a reusable lunar lander with an independent cargo unloader  

NASA Astrophysics Data System (ADS)

Project UM-Haul is the preliminary design of a reusable lunar transportation vehicle that travels between a lunar parking orbit and the lunar surface. This vehicle is an indispensible link in the overall task of establishing a lunar base as defined by the NASA Space Exploration Initiative. The response to this need consists of two independent vehicles: a lander and an unloader. The system can navigate and unload itself with a minimum amount of human intervention. The design addresses structural analysis, propulsion, power, controls, communications, payload handling and orbital operations. The Lander has the capacity to decend from low lunar orbit (LLO) to the lunar surface carrying a 7000 kg payload, plus the unloader, plus propellant for ascent to LLO. The Lander employs the Unloader by way of a motorized ramp. The Unloader is a terrain vehicle capable of carrying cargoes of 8,500 kg mass and employs a lift system to lower payloads to the ground. The system can perform ten missions before requiring major servicing.

Implementation of the Fast-JX Photolysis scheme (v6.4) into the UKCA component of the MetUM chemistry-climate model (v7.3)  

NASA Astrophysics Data System (ADS)

Atmospheric chemistry is driven by photolytic reactions, making their modelling a crucial component of atmospheric models. We describe the implementation and validation of Fast-JX, a state of the art model of interactive photolysis, into the MetUM chemistry-climate model. This allows for interactive photolysis rates to be calculated in the troposphere and augments the calculation of the rates in the stratosphere by accounting for clouds and aerosols in addition to ozone. In order to demonstrate the effectiveness of this new photolysis scheme we employ new methods of validating the model, including techniques for sampling the model to compare to flight track and satellite data.

2-MASS sources with 12um excesses  

NASA Astrophysics Data System (ADS)

We will observe 14 main-sequence stars with 12 micron excesses, indicating the presence of warm (temperature of order 300 K) circumstellar dust debris disks. We discovered these systems using 2MASS J, H, Ks photometry, to estimate photospheric SEDs, and IRAS FSC or SSC 12 micron photometry. The dust is located at about 1--10 AU from the stars, in possible asteroidal clouds. We will obtain IRAC 3.6, 4.5, 5.8, and 8 micron very precise photometry (S/N > 100) to search for the hottest dust, and therefore the innermost edge, of the disks. Through IRS 5.3--21.8 micron spectroscopy (S/N > 20) we will search for PAH 6.2, 7.7, 8.6, and 11.3 micron features, and 10 and 20 micron silicate emission features. We will also search for colder dust, more distant from the stars, in Kuiper Belt-like regions, through MIPS 24 micron photometry (S/N > 20).

Laser damage testing for ion beam sputtered optical coatings at 2 um and 3 um  

NASA Astrophysics Data System (ADS)

Precision Photonics Corporation (PPC) has developed high Laser Damage Threshold (LDT) coatings for the important 2-3?m spectral region. Accurate information for both LDT and absorption for such coatings is sparse and often unreliable, especially when compared to the huge amount of information for these parameters in the 1?m spectral region. The goal of this effort is to provide useful, accurate information for high power/energy coatings, given the limited LDT and absorption testing capabilities for the 2-3?m region. In this paper, we present data for 2?m pulsed LDT, 2?m absorption, 3?m pulsed LDT, and Continuous Wave (CW) LDT data.

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.

Characteristics of Photonis 6-um pore microchannel plates  

NASA Astrophysics Data System (ADS)

We report on the performance of 6 micrometer pore diameter Microchannel Plates (MCPs) fabricated in 50 X 50 mm2 format, from both standard and radio-isotope free low noise glass, by Photonis SAS for a European Space Agency Technology Research Program. We compare them to MCPs manufactured by Photonis (the former Philips Photonics) for the High Resolution Camera (HRC) on NASA's Chandra X-ray observatory. The new MCPs represent a significant advance in MCP technology, having a much larger area than previously reported 6 micrometer plates, and demonstrating low noise 6 micrometer technology for the first time. The 6 micrometer plates are shown to be, mechanically, exceptionally well made with a defect density reduced by a factor of 2 - 5 compared to samples from the HRC flight blocks. They exhibit excellent gain and the expected 0.28 keV (Carbon K) X-ray quantum efficiency. The low noise plates have a very uniform response to X-rays but the standard glass MCPs do show inhomogeneity on both the global and multifiber scales.

SecA ATPase is a critical member of the Sec family, which is important in the translocation of membrane and secreted polypeptides/proteins in bacteria. Small molecule inhibitors can be very useful research tools as well as leads for future antimicrobial agent development. Based on previous virtual screening work, we optimized the structures of two hit compounds and obtained SecA ATPase inhibitors with IC50 in the single digit micromolar range. These represent the first low micromolar synthetic inhibitors of bacterial SecA and will be very useful for mechanistic studies.

Process characterization of 100-um-thick photoresist films  

NASA Astrophysics Data System (ADS)

The number of lithographic applications that require the use of photoresist thickness of one hundred microns or more is rapidly increasing. Extremely large structure heights and high aspect ratios are often required for micro- electrodeposition of mechanical components such as coils, cantilevers and valves. These ultra-thick photoresist can also be used as a mold in micro-electromechanical systems. Ultra-thick photoresist are also used in bump bond applications to define the size and location of the bonds for advanced flipchip packaging.

Photoresist technology for 0.25-um lithography  

NASA Astrophysics Data System (ADS)

It has been the general opinion of device manufacturers that deep ultraviolet (DUV) imaging will be the imaging method required to produce 250nm and sub-250nm geometries for 256Mb-DRAMs and related logic technology. Traditional I-line lithography may not be capable of manufacturing at these geometry's and the use of DUV radiation with 'chemically amplified' photoresists will be required for these device programs. Issues regarding the problems that researchers are combining or have not yet considered in the evolutionary chain of DUV photoresist development and implementation will be discussed. As researchers continue developing environmentally stable materials, there is a series of issues that device manufacturers need to resolve today as new quarter micron fabs are currently under construction. Fab designers may need to consider additional space for specialty tools or processes in order to produce quarter micron lithography. The issues concerning materials, process, reflectivity control, manufacturing facilities, quality control, photoresist manufacturing, photoresist cost and a proposed roadmap for the next several years of development will be discussed. The author will also provide a brief overview of current I-line photoresists and their capability to the 300nm geometry region along with some basic chemistry regarding the principles of DNQ's and chemically amplified photoresists.

Laser pattern-generation technology below 0.25 um  

NASA Astrophysics Data System (ADS)

The projected rapid reduction in mask minimum feature size from the 250 nm to the 100 nm wafer generation will drive laser pattern generators to deep UV wavelengths. Commercially available sources exist in the 250 nm wavelength region using nonlinear optical materials to frequency double longer wavelength laser lines. Nonlinear optical materials, such as SBBO and KBBF, exist for wavelengths below 200 nm but they have not been commercialized. Second harmonic generation in intracavity or mode-locked, external resonant-ring laser configurations can be used to produce sub-200 nm radiation. Existing system architectures are shown to be easily modified to use pulsed sources with a high repetition rate. Advances in nonlinear optical materials, laser design, and system architecture will ensure that laser pattern generation will be an effective maskmaking technology for the next decade.

2.7-um diode-pumped fiber laser  

NASA Astrophysics Data System (ADS)

The performances of the diode-pumped 2.7 micrometers fiber laser have been studied. From the population inversion estimated for a fluorozircoaluminate (AZF) glass with different ErF3 doping, a higher gain was expected for a higher ErF3 doping. The laser performances were improved by adjusting fiber length. Maximum output power of 18.5 mW and slope efficiency of 7% were obtained by using 10 mol% ErF3 doped, 25 mm long AZF fiber in the 800 nm pumping. A cw lasing was achieved by diode pumping at 0.98 micrometers and the effect of Yb3+ sensitization was discussed to improve the performance.

Optical gain and loss in 3-um diode W lasers  

NASA Astrophysics Data System (ADS)

Gain in broad area mid-infrared diode W lasers ((lambda) =3- 3.1micrometers ) has been measured using lateral mode spatial filtering combined with the Hakki-Paoli approach. The internal optical loss of approximately equals 19cm-1 determined from the gain spectra was the same for devices with either 10- or 5-period active regions and nearly constant in the temperature range between 80 and 160K. Analysis of the differential gain and spontaneous emission spectra shows that the main contribution to the temperature dependence of the threshold current is Auger recombination, which dominates within almost the entire temperature range studied (80-160K).

Resection of parenchymatous organs using pulse YAG:Nd laser radiation at 1.44-um and 1.32-um wavelengths  

NASA Astrophysics Data System (ADS)

We have demonstrated that when using in surgical operations the radiation of YAG:Nd laser with 1.44 micrometers wavelength exhibits better cutting capabilities as compared to the same laser at 1.32 micrometers wavelength. The laser scalpel at 1.44 micrometers also provides adequate hemostasis at non-typical section of parenchymals without blood vessel ligation, however this capability is higher for 1.32 micrometers radiation. It is possible to combine the advantages of both radiations by repetitive switching the laser between two wavelengths or mixing two simultaneously generate wave in one optical waveguide. Application of several YAG:Nd laser wavelengths with different absorption coefficients in a single operation on the soft tissue allows one to coagulate large-scale blood vessels and to minimize thermal damages of surrounding tissue.

Laser-tissue interaction of a continuous-wave 2-um, 3-um cascade oscillation fiber laser: sharp incision with controlled coagulation layer thickness  

NASA Astrophysics Data System (ADS)

We studied coagulation layer controlled incision with newly developed continuous wave 2 micrometer, 3 micrometer cascade oscillation fiber laser in vitro. Since this laser device simultaneously oscillates 2 micrometer and 3 micrometer radiation, we could change tissue interaction by arranging power ratio of 2 micrometer to 3 micrometer radiation. About one watt of total irradiation power with various power ratios was focused to extracted fresh porcine myocardium or anesthetized rabbit on an automatic moving stage to obtain line incision. Macro photograph and microscopic histology were used to observe tissue interaction phenomenon. The incised specimen showed that precise cutting groove with thin coagulation layer was attained by a 3 micrometer based radiation, meanwhile addition of 2 micrometer radiation to 3 micrometer radiation made coagulation layer thicker. A heat conduction simulator using finite-element method was used to qualitatively explain obtained coagulation layer thickness. This precise incision with controllable side coagulation layer may effective to control bleeding during incision, for instance, for skin, liver, and kidney incisions. Pure continuous wave radiation of 2 micrometer and 3 micrometer may eliminate stress wave induced tissue damage which is frequently found in Ho:YAG and/or Er:YAG tissue interactions. Moreover, sapphire fiber might offer flexible power delivery to this new laser to establish endoscopic application and/or to improved beam handling.

Recognition of favorable zones for uranium and thorium accumulation, at Um Ara-Um Shilman granitic pluton, South Eastern Desert, Egypt, using airborne spectrometric and magnetic data  

NASA Astrophysics Data System (ADS)

The objective is aimed at identifying significant U and Th anomalies, the amount of re-mobilization of U and Th, the structural framework of the granite pluton and the distribution of spectrometric anomalies. The study revealed that the granite pluton could be represented as a single radio-lithologic unit excluding abnormal measurements exceeding X¯ + 2S. It also revealed the existence of eight strong spectrometric anomalies. Observed values of eU correlate well with eTh, r = 0.72, while the correlation between eU/eTh and eU is lacking, r = 0.190. Meanwhile, there is a negative correlation between eU/eTh and eTh, r = -0.335. This deficiency in correlation suggests a limited or zero remobilization of uranium, which was partly governed by magmatic processes. An interpretative basement structural map of the study-area showed some striking features: four NW-trending faults of first-order magnitude (probably shear zones); three NE-trending faults of second-order magnitude; a series of third-order magnitude faults trending in different directions and, questionably, strike-slip faults as well as some basic and acidic dykes. Most of the radioactive anomalies were found within or near the major contact faults which may act as channels for mineralized fluids from the subsurface. These fluids possess increased concentrations of U and/or Th which could exist in appropriate chemical and/or structural traps. The U and Th anomalies were found to be associated with the northern and southern parts of the granite pluton respectively. The difference between the northern and southern parts of the granite pluton may be attributed to differences in radioelement content, the effect of partial and/or complete digestion of older rocks, or to different levels of erosion.

Mild steels coated with 14% manganese covered electrodes (E7-UM-200-K and E1-UM-350): Phenomena at the steel-coating interface  

SciTech Connect

In this work the authors have studied the phenomena in the interface of the coating made on soft carbon steel with electrodes with a high content of manganese. The study has been done with scanning electron microscope and X-rays mapping images. These images show how the alloy elements are distributed in each of the constituent elements presented in the interface, and the nature of these constituents. These results have allowed us to verify that many of the problems that arise in homogeneous joints, as such localised corrosion, low interface resistance, etc., happened, precisely in these regions. As a help to determine the nature of the constituent elements, microhardness measurements have also been made.

Comparing the use of 4.6 um lasers versus 10.6 um lasers for mitigating damage site growth on fused silica surfaces  

SciTech Connect

The advantage of using mid-infrared (IR) 4.6 {micro}m lasers, versus far-infrared 10.6 {micro}m lasers, for mitigating damage growth on fused silica is investigated. In contrast to fused silica's high absorption at 10.6 {micro}m, silica absorption at 4.6 {micro}m is two orders of magnitude less. The much reduced absorption at 4.6 {micro}m enables deep heat penetration into fused silica when it is heated using the mid-IR laser, which in turn leads to more effective mitigation of damage sites with deep cracks. The advantage of using mid-IR versus far-IR laser for damage growth mitigation under non-evaporative condition is quantified by defining a figure of merit (FOM) that relates the crack healing depth to laser power required. Based on our FOM, we show that for damage cracks up to at least 500 {micro}m in depth, mitigation using a 4.6 {micro}m mid-IR laser is more efficient than mitigation using a 10.6 {micro}m far-IR laser.

Process optimizations have been done to carried out on '0.13micrometers ' reticle manufacturing with feature sizes of under 520nm. Micro-leading < 10nm and CD uniformity (3S) < 10nm process for binary Cr reticle can be achieved with dry etching process using chemical amplify resists blanks. HL-950 writer with resist films of 400nm and dy etching with Centura system were adopted for the purpose. It has shown that by optimizing selectivity window in Centura system without assistant gas addition, one could improve the process capability significantly. Design of experiment was applied to investigating the effects of source power, bias power and total pressure on CD uniformity, Micro-loading, Linearity and Process bias. With the DOE results, the process conditions could be fine-tuned to an optimal set of variables, which allow us to manufacture 0.13 micrometers masks.

Mineral chemistry of albite-enriched granitoids at Um Ara, Southeastern Desert, Egypt  

SciTech Connect

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.

New development of cost-effective sub-0.18-um lithography with i-line  

NASA Astrophysics Data System (ADS)

To reach the sub-0.3 micrometer contact hole pattern by i-line lithography, some advanced technology was introduced such as Phase Shift Mask (PSM) and/or photoresist (PR) flow process. It may be possible that the contact hole is patterned with 0.18 micrometer resolution by the PR flow process with PSM. However, PSM cause the Tg temperature of resist down at the phase shift area. And it also leads the bulk effect by the different pattern density at the cell edge. Thus, during the PSM + PR flow process, 'contact shift' and 'contact distortion' (so-called 'Eyebrow') defects are unavoidable. To repel these defects, we designed the new lithographic process; the UV-bake before thermal flow process. By the UV light at 130 +/- 10 degrees Celsius, the resist was cured at the resist surface. This surface-cured resist has the higher Tg temperature even the normal PSM reticle induces the Tg down. Top surface curing (hardening) also minimized the bulk effect. To maximize the UV bake effects, we developed new resist which was optimized to UV-bake process. By UV-bake process with new resist, the 0.2 micrometer contact hole was patterned. ET margin was 14 nm/10 mJ, and DOF margin was 0.6 micrometer at the mass fabrication device. The 'Eyebrow' and contact shift defects are not detected.

Comparison of I-line and deep-UV technologies for 0.35-um lithography  

NASA Astrophysics Data System (ADS)

An experimental comparison of i-line lithography and deep-UV lithography was performed for 0.35 micrometers patterning of isolation level, polysilicon level, and the contact level. Both techniques used standard illumination and standard masks. The i-line process used conventional single level DNQ resists. The deep-UV work used a commercially available single level chemically amplified positive resist, with additional use of bottom-layer organic anti-reflective layers on some levels. The results highlighted the problems of pushing i-line lithography to the 0.35 micrometers regime and demonstrated the manufacturable process latitudes available with deep-UV lithography.

Experiments and PIC Simulations on the UM Large Area, ECR Electric Propulsion Neutralizer  

NASA Astrophysics Data System (ADS)

We report experimental and simulation results of the Getty ECR plasma source [1, 2], as a plasma neutralizer for electric propulsion. This device generates a uniform plasma over a large ECR area created by rows of permanent magnets placed between a large, S-band microwave horn and a chamber. The metal magnet bars are cross-polarized to minimize microwave reflection. Electron densities are overdense (up to 6E11 /cc) with 2.45 GHz at 100's W. Currents were extracted by biasing a collector positively with both pulsed and DC power supplies. For low DC voltages, electron currents were measured (rather than discharge currents). Experimental parameters: gas pressure, extraction voltage, microwave power, and the position and size of the collector were varied and compared. 2D MAGIC simulations of this source confirmed that most energy transfer from the microwaves into particles occurs near the ECR region, and cross-field diffusion is under investigation with MAGIC.

Simplified 2-D Optical Proximity Correction (OPC) algorithms have been devised, calibrated and implemented on a state-of- the-art 0.25 micrometer random logic process in order to reduce metal line pullback on critical layers. The techniques used are rules-based, but are characterized by fast and robust data conversion algorithms, calibrations based on actual process data improvements in reticle manufacturability, and inspectability of the resultant OPC corrected reticles. Application to local interconnect and metal patterning has corrected fundamental yield-limiting mechanisms in these levels.

Megapixel HgCdTe MWIR focal plane array with a 15-um pitch  

NASA Astrophysics Data System (ADS)

In this paper we present the first demonstration at LETI infrared laboratory of a megapixel HgCdTe MWIR focal plane array with a 15?m pitch. The detectors were interconnected by indium bumps to the CMOS readout circuit. The design of these interconnections has been adapted from the standard CEA-LETI process to achieve resolution and uniformity required by the reduced pitch: the indium bumps scale 12µm width and 7µm height. Because of the important mechanical constraints induced by the size of the component, specific developments were necessary in order to achieve the hybridization process with an extremely reduced amount of defaults. The readout circuit was designed in a 3.3V /0.35?m CMOS technology. Its main features were to allow the validation of the hybridization and technological processes. A Megapixel IRCMOS has been mounted in a dewar and fully characterized at 77K exhibiting excellent electro-optical performances and an operability greater than 99.8%.

Current measurements in plasma produced by the train of 10.6-um subnanosecond laser pulses  

NASA Astrophysics Data System (ADS)

Results of current probe measurements for a plasma produced by the train of approximately 200 ps 10.6 micrometers laser pulses are reported. The train of pulses was obtained as a result of regenerative amplification of approximately 100 ps laser pulse in a 5 cm aperture 6 atm TE-CO2 laser. Experiments were carried out for Wo and Al targets dispersed in vacuum, two values of the interpulses separation in the train (Delta) T equals 9.3 and 29 ns and wide range of energy density on the target, corresponding to peak intensities of single pulses Ip equals 1 divided by 300 GW/cm2. Experiments had shown large difference of temporal structure of current signal with Wo and Al targets due to the considerable different in melting temperatures of these materials as well as radiation loses of laser plasma. We detected large ratio of current signal amplitudes for targets irradiation by the pulse train or gain switched pulse generated in TE-CO2 laser without injection of a short pulse. Results of these measurements are compared with those earlier obtained for nanosecond pulse train.

Pulpal safety of a 9.6-um TEA CO2 laser used for caries prevention  

NASA Astrophysics Data System (ADS)

Lasers are used for several procedures involving hard and soft tissues of the oral cavity. Included in those procedures is the use of the CO2 laser to alter the surface structure of tooth enamel to render it more resistant to caries. A new 9.6micrometers wavelength TEA CO2 laser (Argu Photonics, Jpiter, FL) has been investigated as a device that can be used for this procedure without harming the dental pulp. Erupted, caries and restoration free third molars (n=24) were used in the experiment. Teeth were irradiated at an incident fluence of 1.5J/cm2 and a repetition rate of 10Hz and a spot size 1mm in diameter. At the low and high settings, 200 to 400 pulses were delivered at 12mJ per pulse for a total energy of 2.4 or 4.8J delivered for 20 or 40 seconds respectively. Other teeth were subjected to a sham dental procedure (positive control) or no procedure (negative control). Prior to testing, radiographs were taken of all teeth, and they were tested pulpally using heat, cold and electricity to determine vitality. The teeth were removed either immediately or at one week or one month after testing. They were bioprepared and examined histologically for signs of inflammation. Only one tooth developed symptoms of sensitivity to cold for 10 days following exposure to the high power level. The sensitivity was of fleeting duration and was judged to be reversible pulpitis. All teeth tested responded normally at pretesting and pre-extraction time periods. Histological examination disclosed no indication of an inflammatory response in the pulp tissue. All sections appeared normal with no changes seen in the normal pulpal morphology. We conclude that the 9.6 micrometers wavelength laser causes no pulpal damage at the energy levels used and can be used safely for caries prevention treatments.

Process control for 0.25 um GaAs microwave monolithic integrated circuits  

NASA Astrophysics Data System (ADS)

Gallium arsenide metal semiconductor field effect transistors (GaAs MESFETs) are used in analog microwave monolithic integrated circuits (MMICs) because of their high frequency response. Common applications for MMICs include low noise and power amplifiers for use in satellite communication and missile guidance systems. The performance of MESFETs is improved with smaller gate lengths, but to consistently achieve the highest performance, control methods must be in place for the critical processes. Gate length control is the key parameter in maintaining the rf performance and a lack of gate pinch off is the major yield loss category. This paper describes the process and the tools that Texas Instruments uses to monitor the critical parameters. It also describes the control methods and reviews the major contributors to variations in the process.

High-power 2-um diode-pumped Tm:YAG laser  

NASA Astrophysics Data System (ADS)

Using a scalable diode end-pumping technology developed at Lawrence Livermore National Laboratory we have demonstrated a compact Tm:YAG laser capable of generating greater than 50 W of cw 2 micrometer laser output power. The design and operational characteristics of this laser, which was built originally for use in assessing laser surgical techniques, are discussed. The 2 micrometer radiation produced by the 3F4 - 3H6 transition of Tm3+ has many practical applications because it is strongly absorbed by water and also because it is an 'eye-safe' wavelength. The strong absorption of 2 micrometer radiation by water makes this transition a very attractive candidate for performing laser surgical procedures as most tissue types are predominately composed of liquid water. The fact that 2 micrometer radiation is considered 'eye-safe' makes this transition attractive for laser range finding and remote sensing applications where other laser wavelengths could pose a safety hazard. At sufficiently high doping densities, Tm3+ exhibits a beneficial two-for-one quantum pump efficiency enabling well developed AlGaAs laser diode arrays to be used as efficient excitation sources. Many applications requiring 2 micrometer laser radiation such as remote sensing, laser radar, anti sensor, sensor spoofing, and OPO pumping have driven the development of diode pumped all solid state TM3+ laser systems because of their potential for efficiency, compactness, and ruggedness. Here we focus on Tm3+:YAG and the scalable diode end-pumping technology developed at LLNL which enables higher average power operation of diode pumped Tm3+ laser systems than has previously been possible. To date we have demonstrated cw operation of this laser to power levels of 51 W. The end-pumping technology used is the same as was previously used to demonstrate a 100 mJ Q-switched Nd:YLF laser.

High-reliability nonhermetic 1.3-um InP-based uncooled lasers  

NASA Astrophysics Data System (ADS)

We report the first uncooled non-hermetic 1.3 micrometer InP-based communication lasers that have reliability comparable to their hermetically packaged counterparts for possible applications in fiber in the loop and cable TV. The development of reliable non-hermetic semiconductor lasers would not only lead to the elimination of the costs specifically associated with hermetic packaging but also lead the way for possible revolutionary low cost optoelectronic packaging technologies. We have used Fabry-Perot capped mesa buried heterostructure (CMBH) uncooled lasers with both bulk and MQW active regions grown on n- type InP substrates by VPE and MOCVD. We find that the proper dielectric facet passivation is the key to obtain high reliability in a non-hermetic environment. The passivation protects the laser from the ambient and maintains the proper facet reflectivity to achieve desired laser characteristics. The SiO facet passivation formed by molecular beam deposition (MBD) has resulted in lasers with lifetime well in excess of the reliability goal of 3,000 hours operation at 85 degrees Celsius/90% RH/30 mA aging condition. Based on extrapolations derived experimentally, we calculate a 15 year average device hazard rate of less than 300 FITs (as against the desired 1,500 FITs) for the combination of thermal and humidity induced degradation at an ambient condition of 45 degrees Celsius/50% RH. For comparison, the average hazard rate at 45 degrees Celsius and 15 years of service is approximately 250 FITs for hermetic lasers of similar construction. A comparison of the thermal only degradation (hermetic) to the thermal plus humidity induced degradation (non-hermetic) indicates that the reliability of these nonhermetic lasers is controlled by thermal degradation only and not by moisture-induced degradation. In addition to device passivation for a non-hermetic environment, MBD-SiO maintains the optical, electrical and mechanical properties needed for high-performance laser systems.

Direct spectral comparison of the InGaAs image intensifiers are made to standard Generation II and III image intensifiers. Then we study the sealed NEA InGaAs image tube performance parameters such as spectral sensitivity, whitelight photoresponse, equivalent background illumination, signal-to-noise, modulation transfer function, and optical system-image intensifier field performance data.

The output fluence of a high peak power laser like the French laser project 'Laser Megajoule' is strongly related to the damage threshold of mirrors and polarizers consisting of multilayer dielectric coatings. It has been recognized for a long time that growth defects as nodules are playing a significant role in 1.06 micrometers laser damage of these components. In order to determine the critical parameters of the nodule and the associated mechanisms during the laser damage process, we have performed laser irradiation of samples inside the vacuum chamber of a scanning electron microscope (SEM). The SEM allows us to choose a particular area of the sample and to observe it before and after irradiation at a micro size scale. The damage evolution ca be analyzed shot by shot. In this paper, the experimental method is described. SEM pictures of irradiated laser shots are showed. Data about damage mechanisms are derived from these very high resolution morphological observations.

Improved design and prototyping for a 10/20-um camera/spectrometer for ESO's VLT  

NASA Astrophysics Data System (ADS)

The Cassegrain focus of the 2nd unit telescope of ESO's VLT shall be equipped with a 10/20 micrometers camera spectrometer. This instrument shall be built by a consortium of institutes from ESO's member-states responsible for the final design. Still rather detailed internal studies were required to assess the overall scope of work, the repercussions on the telescope design and the required infrastructure at ESO. The internal studies have resulted in a multimode instrument allowing for diffraction limited imaging with variable magnification at 10/20 micrometers , low-, medium- plus potentially high-resolution long slit spectroscopy (approaching or exceeding (lambda) divided by (Delta) (lambda) approximately equals 50000). The optical design allows to take advantage of the rapid evolution in the field of detectors. Novel design features are an exchangeable entrance window, an anamorphic beam expansion and potentially the use of immersion gratings. At the La Silla observatory TIMMI, a small 10 micrometers camera/spectrometer for the 3.6 m telescope (built by the Service d'Astrophysique, CEN- Saclay, France) is in operation to allow both ESO and its community to gain practical experience in astronomy in the 10 micrometers atmospheric window. This instrument is currently equipped with a 64x64 element Ga:Si array. A 128x196 element array is presently in development at Leti/LIR of Grenoble, France, which may be used to upgrade ESO's current observing capabilities. Spectroscopy in TIMMI utilizes Germanium grisms machined via anisotropic etching. This manufacturing technology may also serve to fabricate immersion gratings from high index materials.

Long-wavelength optical coherence tomography at 1.7 um for enhanced imaging depth  

PubMed Central

Multiple scattering in a sample presents a significant limitation to achieve meaningful structural information at deeper penetration depths in optical coherence tomography (OCT). Previous studies suggest that the spectral region around 1.7 µm may exhibit reduced scattering coefficients in biological tissues compared to the widely used wavelengths around 1.3 µm. To investigate this long-wavelength region, we developed a wavelength-swept laser at 1.7 µm wavelength and conducted OCT or optical frequency domain imaging (OFDI) for the first time in this spectral range. The constructed laser is capable of providing a wide tuning range from 1.59 to 1.75 µm over 160 nm. When the laser was operated with a reduced tuning range over 95 nm at a repetition rate of 10.9 kHz and an average output power of 12.3 mW, the OFDI imaging system exhibited a sensitivity of about 100 dB and axial and lateral resolution of 24 µm and 14 µm, respectively. We imaged several phantom and biological samples using 1.3 µm and 1.7 µm OFDI systems and found that the depth-dependent signal decay rate is substantially lower at 1.7 µm wavelength in most, if not all samples. Our results suggest that this imaging window may offer an advantage over shorter wavelengths by increasing the penetration depths as well as enhancing image contrast at deeper penetration depths where otherwise multiple scattered photons dominate over ballistic photons.

We investigate a laser range finder for obstacle detection in automotive field. This device is based on the use of an eye-safe pulsed microchip laser, emitting near 1.55 micrometer. The technology of solid-state microchip lasers is a good way to obtain a compact, reliable and low cost laser source. Passively Q-switched microchip lasers are of great interest for time of flight range finding: short pulse duration and high peak power have been obtained. A short pulse duration gives good precision and high peak power gives a long range of detection. The distance measurement is obtained with an ASIC chronometer which implements the time-of- flight technique. We also developed reception circuit for start and stop signals and data input/output. The ASIC chronometer is based on two complementary techniques: a clock counter for coarse measurement and multiple slopes generator for fine measurement.

Zum Auf und Ab des Meeresspiegels in Skandinavien: Langer Streit um Eustasie oder Isostasie  

NASA Astrophysics Data System (ADS)

The phenomenon of the rise of the Scandinavian shield during the Holocene and the concomitant fall in level of the Baltic Sea has been investigated for centuries. Already in medieval times, there were reports about the coastlines of the Gulf of Bothnia that are full of relevant observations. During the eighteenth century, scientists such as Celsius and Linnaeus collected observations such as these. The result was that the search for the possible explanations of this rise-and-fall phenomenon intensified. The generally favoured explanation was that there was an active sinking of sea level in the Baltic rather than an active rising of the land surface in Fennoscandia. This was because water was seen as mobile, in contrast to a „terra firma". The relevant discussion was often emotional, and here, we try to illustrate it using material from the Geologenarchiv Freiburg (von Hoff, von Buch and Goethe). No more than a few decades later, it became obvious by the theory of Ice Age that both the sea level and the land could be mobile (eustatic sea level changes—glacial isostasy). Additionally, of course, plate tectonics had some influence: Norway is situated at the western end of the Eurasian plate and is part of a passive continental margin. There are still open research problems, many of which can be addressed using modern methods of satellite-based geophysics and geodesy. Some other aspects as the permanent uplift trend of Scandinavia since the Cambrium or the rhythmic to and fro of magma in the upper mantle during the Pleistocene are mentioned.

High-performance 1.3-um laser diode by LP-MOVPE  

NASA Astrophysics Data System (ADS)

The progress in 1.3 micrometers wavelength InGaAsP/InP lasers for optic fiber communication and subscriber loop applications is reviewed. By using LP-MOVPE/LPE epitaxy techniques, the performance of commercial optical devices is considerably improved. The bandwidth of the 1.3 micrometers uncooled MQW-LD module could be high to 1.6GHz, threshold current Ith < 15mA, maximum fiber output power Pf >= 20mW while uniformity, reproducible, high yield are achieved. Further by growing active layer with compressive strained structure the lowest threshold current Ith equals 3.8mA was achieved with high reflection coating and the temperature performance of the SL-MQW-LD has been greatly improved, the change of slop efficiency at 25 degrees C and 85 degrees C is less than 1 dB. Using the holographic technique a high power 1.31 micrometers InGaAsP/InP multiquantum well distributed feedback laser has also been developed. The fiber output power of butterfly packaged module with optic isolator Pf > 10mW, threshold current Ith < 18mA, slop efficiency Es > 22 percent and side mode suppression ratio SMSR > 40dB. The composite triple beat CTB < -66dBc and the composite second order CSO < -56dBc by test frequencies equals 55.25 to approximately 289.25MHz with 40 NCTA channels, the carrier to noise ration CNR > 50 dB and the relative intensity noise RIN < -160dB/Hz.

Earth's spectral albedo from 0.5 to 4.4 um  

NASA Astrophysics Data System (ADS)

We have analyzed spectroscopic earthshine data to determine Earth's nightly spectral albedos covering the visible, near and middle infrared spectral ranges. Observations in the visible were undertaken from Palomar Observatory with the spectrograph in the Palomar 60" telescope and with the echelle spectrograph of the InfraRed Telescope Facility (IRTF) on Mauna Kea in Hawaii. The observing runs were chosen near the quarter moon to reduce the background glow produced by the moonshine (bright side of the Moon). Although observations were taken on different nights, the similarity of lunar phases and comparable cloud cover conditions for the monitored part of the Earth's surface, allow us to derive, for the first time, an apparent albedo of the Earth covering the entire spectral range from 0.5 to 4.4 microns.

Application of RTA to a 0.8-um BiCMOS process  

NASA Astrophysics Data System (ADS)

RTA has been established as a key process element in a sub-micron BiCMOS flow. The major advantage of RTA is that a temperature pulse > 1000 degree(s)C can be used to break-up the interfacial oxide in the polysilicon emitter contact to provide enhanced current gain with low-emitter resistance but with little impact on the CMOS. The RTA emitter anneal also serves to simultaneously flow BPSG to planarize the wafer prior to metallization. Contact reflow is also advantageous for a tapered structure to improve metal step-coverage.

Characteristics of GaInNAsSb/GaAs VCSELs operating near 1.55um  

NASA Astrophysics Data System (ADS)

A detailed study of the high-power pulsed operation of C-band optically-pumped GaInNAsSb vertical cavity surface emitting lasers is reported. The devices employ a resonant periodic gain structure grown by molecular beam epitaxy on a GaAs substrate with a 31-pair GaAs/AlAs bottom distributed Bragg reflector and a 4-?, GaAs-based resonant cavity containing 10 GaInNAsSb quantum wells distributed among the 7 antinodes of the electric field. A dual-pump-band SiO2/TiO2 dielectric top mirror allows efficient optical pumping via low reflectivities at 808nm and 1064nm while providing very high reflectivity at the 1.55?m target emission wavelength. The laser characteristics were evaluated using both a Q-switched Nd:YAG 1064nm pump and a 20W-peak 180ns-pulsed 850nm diode laser. The importance of the gain-cavity detuning was evident from time-dependent spectral measurements of laser material subjected to post-growth annealing at different temperatures between 725 and 775°C. The highest annealing temperature produces the largest blue shift of the gain peak relative to the cavity resonance, resulting in the best power transfer characteristics as well as reduced temperature sensitivity.

1.06 um Nd:YAG laser coagulation tonsillectomy: an animal study  

NASA Astrophysics Data System (ADS)

Tonsillectomy is one of the most frequently performed surgeries which is not free from post- operative morbidity. We have developed a non contact photocoagulation technique using 1.06 micrometers Nd:YAG laser and tested its safety and efficacy in an animal model. Eight animals were divided into the laser coagulation group (6 animals) and the laser excision group (2 animals). Tonsils of the laser coagulation animals were irradiated with 8 - 10 W of laser power for 5 - 6 min in a slow painting-like motion over the surface of a tonsil until slight blanching of mucosa was noticed. Tonsils of the laser excision group were resected with 25 - 30 W of 1.06 micrometers Nd:YAG laser power through a contact fiber. The animals were examined endoscopically at 1.5 hrs and at 2, 5, 12, 30, and 42 days post treatment. Atrophic process was followed until total disappearance of tonsillar tissue was observed. The animals were sacrificed at various time intervals and the tonsillar specimens were collected for gross and histological examination. The thermal damage to mucosa and adjacent tissues was minimal which we attribute to a low laser power and cooling from preoperative injection of saline into subcapsular space. The potential advantages of this technique include intact mucosa with no intra- or post-operative bleeding, less pain, and avoidance of general anesthesia. These advantages may enable this surgery to become an in-the-office procedure.

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

NASA Astrophysics Data System (ADS)

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

IIP Tropospheric Infrared Mapping Spectrometers (TIMS) demonstration of CO retrieval, including multi-layer, from atmospheric data acquired simultaneously in the solar reflective region near 2.3 um and the thermal emissive region near 4.7 um  

NASA Astrophysics Data System (ADS)

The NASA Earth Science Technology Office (ESTO) Instrument Incubator Program (IIP) Tropospheric Infrared Mapping Spectrometers (TIMS) have been developed to demonstrate measurement capability, when deployed in space, for multi-layer retrieval of CO from spectral measurements acquired in the solar reflective (SR) region ~ 4281 to 4301 cm-1 and in the thermal InfraRed (TIR) region ~ 2110 to 2165 cm-1. We describe joint deployment at Denver University (DU) with co-investigators there of the TIMS, and of the DU colleagues FTS, to acquire simultaneous measurements of atmospheric spectra in the SR and the TIR. The FTS provided validation radiance data for the TIMS. The TIMS retrievals of CO, H2O and CH4 agreed well with validation vs these as retrieved from the DU data, AIRS retrieval, standard models and ECMWF. The TIMS CO retrievals included column retrieved from the just the SR data, column retrieved from just the TIR data, and a simple two-layer retrieval from the combined data sets. The data were acquired in an operational mode that mimicked the operations in a conceptual application that would provide footprints, coverage, refresh time as in the Decadal Survey GEO-CAPE mission statement. Very encouraging CO precisions were achieved, e.g., the TIMS CO column retrieval from the SR data demonstrated better than the 10% precision requirement as listed on slide 32 of the GEO-CAPE Reference document http://geo- cape.larc.nasa.gov/docs/GEOMAC_FinalReport_no_costs.ppt

8- to 9-um and 14- to 15-um two-color 640x486 GaAs/AlGaAs quantum well infrared photodetector (QWIP) focal plane array camera  

NASA Astrophysics Data System (ADS)

An optimized long-wavelength two-color quantum well IR photodetector (QWIP) device structure has been designed. This device structure was grown on a three-inch semi- insulating GaAs substrate by molecule beam epitaxy (MBE). This wafer was processed into several 640 X 486 format monolithically integrated 8-9 and 14-15 micrometers two-color QWIP focal plane arrays (FPAs). These FPAs were then hybridized to 640 X 486 silicon CMOS readout multiplexers. A thinned FPA hybrid was integrated into a liquid helium cooled dewar to perform electrical and optical characterization and to demonstrate simultaneous two-color imagery. The 8-9 micrometers detectors in the FPA have shown background limited performance (BLIP) at 70 K operating temperature, at 300 K background with f/2 cold stop. The 14-15 micrometers detectors of the FPA have reached BLIP at 40 K operating temperature at the same background conditions. In this paper we discuss the performance of this long-wavelength dualband QWIP FPA in quantum efficiency, detectivity, noise equivalent temperature difference, uniformity, and operability.

Photonic time stretching of 102-GHz millimeter waves using 1.55-um polymer electro-optic modulator  

NASA Astrophysics Data System (ADS)

Photonic time-stretch has been proposed as a signal preprocessor to perform A/D conversion in otherwise inaccessible high frequency regimes. We have demonstrated time-stretching of MM-wave signals at frequencies up to 102 GHz down to 11 GHz , using an electrooptic modulator fabricated with the new polymer material PC-CLD. This application takes advantage of the inherent wideband capabilities of the PC-CLD material system, which has also demonstrated good optical insertion loss and high non- linearity at 1.55 micrometers . The dispersion penalty inherent to time-stretching imposes an additional bandwidth limit to that imposed by the modulator. A single-sideband modulator configuration is proposed to reduced the effect of this penalty.

Deep ultraviolet positive resist image by dry etching (DUV PRIME): a robust process for 0.3 um contact holes

Classical positive resist process for DUV is not yet available and stabilized. We noticed various limiting points such as the delay time for resist material, the limitation of thickness related to ultimate resolution, and the bulk effect. P.R.I.M.E. (Positive Resist Image by dry Etching) process technology using DUV 248 nm exposure wavelength improve solutions for each process parameters, for example, a well known and stable resist (J.S.R- U.C.B PLASMASK 200G) is used with Hexamethyldisilazane (HMDS) as silylated compound. The combination of DUV exposure and top surface imaging P.R.I.M.E. process can open contact holes down to 0.3 micrometers with a large process window and a good wafer uniformity. This publication will show the improvement of each process parameter. Extended information will be given for process latitude (focus and exposure). We demonstrated and verified the feasibility of the contact holes process by etching 1 micrometers oxide (BPSG + USG) through the PRIME process lithography.

Resist coating optimization on eight inches Deep-UV litho cell: modelization and application to 0.25 um technology  

NASA Astrophysics Data System (ADS)

One of the main problem for 0.25 micrometers features will be the depth of focus; Deep UV source will be necessary, but anyway DOF will be in the one micron range. So will it be possible to have CD in specifications all over the field? Many parameters have to be checked and monitored but the photoresist thickness on wafer is an important part due to the interferences franges created inside the photoresist during exposure. In order to reduce this phenomenon, we are used to choose the thickness on the flat part of the swing curve, for maximum or minimum coupling. As the wavelength is being lower, from 365 nm on i-line steppers to 248 nm on Deep UV steppers, this flat part length is reduced, so to obtain the same CD's repeatability the photoresist thickness uniformity must be improved in Deep-UV. This paper presents an effective method to obtain a Deep UV photoresist uniformity allowing 0.25 micrometers CD's in specification on the whole 8' wafer. A great number of process parameters may affect the resist coating uniformity, so we have decided to use the Designs Of Experiments to solve such a complicated problem with a minimum number of experiments. Due to the centrifuging process used to coat the resist on the wafer, the main uniformity default that can appear is a radial default. So we have chosen a combination of Taguchi and Response Surface Methods, in order to minimize the thickness variations versus the radius. First of all, to evaluate the effects of the 8 process parameters on this response, we have performed a screening design of 16 experiments. A statistical analysis has shown that the thickness variations depend on only 5 parameters. Then a Response Surface design of experiments has been achieved, with 27 experiments. A very accurate modelization of the uniformity default has been carried out from this design, and the optimization has led to a thickness standard deviation of only 3.3 angstrom on the whole wafer. Moreover the quality of the modelization, predictive in the complete domain, will allow to work out further problems.

Planarizing BARC 0.32-um i-line lithography process for the reduction of intradie CD variation  

NASA Astrophysics Data System (ADS)

The effects of increasing bottom-side anti-reflective coating (BARC) thickness on the CD distribution within a device are presented. In conjunction with the increasing BARC thickness, reductions in the photoresist thickness are shown to be beneficial. Significant reductions in CD variability and increases in the depth of focus versus CD spread are achieved with increased BARC and reduced photoresist thickness. Although significant improvements are seen with a thicker BARC film for the photolithography process, the importance of optimizing the etch process for the thicker films is shown. The effects of CD distribution on important electrical device parameters are also presented.

Pulsed-laser-induced damage in semiconductors Ge, ZnS, and ZnSe at 10.6um  

NASA Astrophysics Data System (ADS)

Laser irradiation induced damage to several materials of interest for use as 10.6 micrometers laser system windows is investigated in this paper. The irradiation source in these single shot experiments was a pulsed TEA CO2 laser. Damage initiation in semiconductors has been studied during the interaction by measuring the variation of the transmitted intensity of a He- Ne and a CO2 cw lasers through the samples. Results show that damages appear at the beginning of the laser-matter interaction process on both surfaces and in the bulk of the materials. The damaged materials have been characterized for various incident fluences by means of optical microscopy and scanning electron microscopy in terms of topography and morphology. The modified surface chemical analysis and the structural analysis have been carried out using energy dispersive x-ray and Raman spectroscopy.

Design of millimeter wave optical modulators with monolithically integrated narrowband impedance matching circuits for 1.3-um photonic links  

NASA Astrophysics Data System (ADS)

To implement millimeter wave photonic links using high speed optical modulators, RF input efficiency to the modulator is an important consideration. In this paper we discuss design and fabrication of ultra high speed multiple quantum well electro-absorption modulators for narrow band applications up to 40 GHz. In order to obtain higher RF efficiency at working frequencies of 20 GHz, 25 GHz and 40 GHz, modulators with monolithically integrated matching circuits were designed and fabricated utilizing co-planar waveguide MMIC technologies. Measurement results show excellent matching at specific frequencies with S11 of -16 dB for the 20 GHz devices, -20 dB for the 25 GHz devices and -36 dB for the 40 GHz devices. At least 6 dB of improvement on optical modulation efficiency can be expected over modulators without impedance matching.

AlGaInAs/InP strained MQW reversed-mesa RWG structure is proposed to reduce leakage current and improve linearity, and applied to make high linearity and high power 1.3 micrometers DFB-LD. For 1.3 micrometers AlGaInAs strained MQW DFB LD, the lasers operated with 10 mA threshold current, 0.48 mW/mA slope efficiency for one facet, 45 dB SMSR. The -3 dB cutoff frequency is 14 GHz, and the eye pattern is opened widely at 10 Gb/s. Under PAL 59 channels test, output power exceeds 15 mW with COS <-69.4 dBc, CTB <-69.4 dBc, CNR <-52 dB, which is the first reported RWG 1.3 micrometers DFB-LD for optical CATV application. This implies that AlGaInAs/InP strained MQW reversed-mesa RWG structure could effectively reduce leakage current.

Implementation of high-contrast novolak resist process for sub-0.5-um e-beam lithography  

NASA Astrophysics Data System (ADS)

The use of interrupt develop has been reported to enhance the contrast and resolution of novolak resist systems for e-beam lithography. Experience with interrupt develop has demonstrated the ability to control sensitivity and contrast independent from the exposure dose. High contrast and flexible sensitivity are primarily due to the interaction of induction effects of the novolak resist and the length of the develop step. The induction effect is primarily dependent on absorbed energy in the resist. Understanding the distribution of absorbed energy in the resist allows use of the induction effect to control resist profile and image size. A sidewall passivation phenomena results from interrupting the develop process. The passivation enhances the directionality of develop, yielding additional resist profile control. Three diazonapthoquinone novolak resists have been implemented for the fabrication of x-ray masks. During implementation of the resists, the molecular weight of the base resin was found to have a major influence on contrast and image quality. The results show the resolution and image size control achieved using systematic interrupt develop processing.

Negative differential gain in 1.3um quantum dot lasers: comparison of self-heating and free carrier effects  

NASA Astrophysics Data System (ADS)

A comparative study of the gain spectra of quantum-dot lasers at high carrier densities is reported. The gain spectra of quantum dot lasers under a constant junction temperature (obtained by the use of Fabry-Perot modes as a temperature gauge) and under constant heat-sink temperatures are measured. Negative differential gain, observed for the ensemble of quantum dot ground-states is shown to be mainly due to free carrier effects, where increasing dephasing effects, combined with saturated gain, result in spectral broadening and a reduction in the peak gain.

Near-achromatic retardance behavior of HN22 Polaroid 3.6 to 5.4 um  

NASA Astrophysics Data System (ADS)

Polaroid HN22, a popular sheet polarizer, has been measured to be a nearly half wave retarder in the 3.6 to 5.4 micrometers spectral band with a transmittance of approximately 20 percent. The exact retardance value may be tuned to the range of 60 degrees - 260 degrees by tilting the HN22 with respect to the incident beam. The material's polarizing effects have been shown to be minimal in this waveband. Its availability, relatively large available aperture, large filed of view, and low cost make HN22 an excellent candidate for use as an IR retarder for systems operating from 3.6 to 5.4 micrometers . As such, HN22 may be used for rotating the plane of polarization of an incident linearly polarized beam as well as to convert between circular polarization states.

~2.1 um Tm3+-Ho3+ co-doped tungsten tellurite single mode fiber laser  

NASA Astrophysics Data System (ADS)

We investigate the spectroscopic and lasing performance of Tm3+-Ho3+ co-doped tungsten tellurite single mode fiber operating around 2.1 ?m with a commercial 800 nm diode laser pump source. The optimum doping concentration of Tm2O3 and Ho2O3 in Tm3+-Ho3+ co-doped TeO2-WO3-La2O3 (TWL) glass is 1 mol% and 0.5 mol%, respectively. The lifetime of Ho3+:5I7 level is 3.3 ms in the bulk glass. The maximum stimulated emission cross-section of Ho3+ in TWL is 10.0×10-21cm2. The tungsten tellurite single mode fibers are prepared by using rod-in-tube method. The infrared emission spectra are compared with varying fiber lengths. Tm3+-Ho3+ co-doped fiber shows weak emission at ~1.9 ?m very strong emission at ~2.1 ?m, which indicates efficient energy transfer from Tm3+ to Ho3+ in the fiber. The 1.47 ?m emission increases with the increment of the fiber length, which means a back energy transfer from Ho3+ to Tm3+. A 106 mW continuous wave laser emission at ~2.1 ?m is demonstrated from a 16 cm length of this fiber, the slope efficiency is 23%, corresponding to a 17% optical to optical efficiency. Lasing has also been achieved in <5 cm length of this fiber, making this material a promising candidate for single frequency ~2.1 ?m laser sources.

In our work, fluorinated amorphous carbon films (a-C:F) was deposited by PECVD. The amorphous carbon films (a-C:F) with low dielectric constant (K-2.3), thermal stability and acceptable adhesion to cap-layer such as SiOF was obtained by optimum of content ration between carbon with fluorine and adding few SiH4 for improvement of adhesion. The etching profile with high aspect ratio and etching selection ration more than 50 (a- C:F/SiOF) were obtained by etching gas of N2+O2. Furthermore, we demonstrated the technology of electroplating copper in trenches or vias as small as 0.15 micrometers , 6:1 AR. The wetting agent system was consisted of mainly two molecular weights polyethylene glycols (PEG). The small molecular weight PEG with better diffusion ability for reducing the surface tension and the larger PEG enhancing grain growth control was proposed for the first time to wet the inner portion of the sub- 150 nm damascene feature. The leveling agent system was mainly heterocyclic compound contained N, S atoms offering sufficient activation over-potential and selective inhibition gradient.

Photoablation with the free-electron laser between 10 and 15 um in biological soft tissue (cornea)  

NASA Astrophysics Data System (ADS)

The ablation depth and collateral thermal damage for pulsed IR photoablation as a function of wavelength with the free- electron laser (FEL) at 10.1, 11.8, 12.8, and 14.5 micrometers wavelengths is investigated. FEL data are compared with the blow-off and the continuous ablation models. Porcine cadaver corneas were used as target material. The experimental data are compared with theoretical calculations for both models. At low water absorption the additional absorption of the cornea was taken into account. FEL data were: energy per pulse between 15.6 and 17.8 mJ, ablation zone around 0.2 mm2, and pulse length 4 microsecond(s) . In this wavelength range an effective photoablation of biological materials with a high water content can be achieved. The measured FEL data of ablation depth fail to confirm the blow-off model, describing ablation depth sufficiently well. The wavelength, collagen absorption contributes to the overall absorption of corneal tissue. The ablation depth can only be described by the continuous ablation model; however, the collateral thermal damage pattern can be described by both models.

Evaluation of 0.4- to 2.2-um atmospheric correction techniques using the spectral similarity scale  

NASA Astrophysics Data System (ADS)

The purpose of this research study is to evaluate the effectiveness of atmospheric correction and radiometric calibration techniques by measuring the differences of corrected data and ground truth spectra. Several atmospheric correction methods have been performed utilizing the ATREM and ACORN software packages. A variety of different settings (14 for ATREM and 5 for ACORN) have been tested and evaluated. The Spectral Similarity Scale (SSS) developed by BAE SYSTEMS is a measure of spectral similarity based on spectral magnitude and shape. The SSS-based spectral comparison process indicates that the default settings for iron rich soils are the best ATREM inputs for the Shelton, NEAVIRIS scene. The SSS comparison of the ACORN results with the spectral ground truth revealed that ACORN with the artifact type 1 was the best correction setting available for both ATREM and ACORN. For atmospheric water we find that ACORN is superior to ATREM. ATREM does correct for gain offsets that ACORN does not correct for with default settings. When used incorrectly, it is possible to severely reduce the spectral accuracy with either software package.

Ultrafast modulation of 1.55-um QW laser structures: optically detected carrier dynamics, limiting mechanisms, and applications  

NASA Astrophysics Data System (ADS)

This paper proceeds from basic research on carrier dynamics to applications in high-speed laser devices. Different retardation mechanisms are studied experimentally and theoretically providing input for the design of high-speed laser devices. Optically detected carrier dynamics in III/V semiconductor quantum well (QW) heterostructures perpendicular to the interfaces is studied. Photoluminescence emissions originating from different semiconductor layers are recorded time-resolved to probe the carrier dynamics between these layers. High spatial and temporal resolution is obtained experimentally, partly even in the nm and sub-ps ranges, respectively. Retardation effects are separated and studied experimentally and theoretically by corresponding model calculations. A material comparison shows that GaInAsP is beneficial due to considerable advantages in technological implementation processes and AlGaInAs is superior from a physical point of view enabling higher modulation band-widths due to larger conduction band discontinuities. The equalization of the carrier densities in the individual wells is found to be mainly retarded by hole thermionic emission. Hole transport in the p-sided confinement layer and electron capture from the p-sided confinement layer is also found to be also a limiting factor. These results are used to optimized AlGaInAs/InP lasers with asymmetric confinement layers. The p-sided confinement layer is reduced on the costs of the n- sided confinement layer to obtain (1) a faster hole transport across the p-sided confinement layer and (2) to accelerate the capture of electrons from the p-sided confinement layers being uncaptured during the transfer across the QWs. In our experiments a modulation bandwidth of 26 GHz is obtained. Even higher values are found in corresponding theoretical model calculations demonstrating an interesting development potential.

Fatigue behavior in water of Y-TZP zirconia ceramics after abrasion with 30 um silica-coated alumina particles  

PubMed Central

Objective The use of a 30 µm alumina–silica coated particle sand (CoJet™ Sand, 3M Espe), has shown to enhance the adhesion of resin cements to Y-TZP. The question is whether or not sandblasting 30 µm particles does negatively affect the fatigue limit (S–N curves) and the cumulative survival of Y-TZP ceramics. Method Four zirconia materials tested were: Zeno (ZW) (Wieland), Everest ZS (KV) (KaVo), Lava white (LV) and Lava colored (LVB) (3M Espe). Fatigue testing (S–N) was performed on 66 bar of 3 mm × 5 mm × 40 mm with beveled edges for each zirconia material provided by the manufacturers. One half of the specimens were CoJet sandblasted in the middle of the tensile side on a surface of 5 mm × 6 mm. Cyclic fatigue (N = 30/group) (sinusoidal loading/unloading at 10 Hz between 10% and 100% load) was performed in 3-point-bending in a water tank. Stress levels were lowered from the initial static value (average of N = 3) until surviving 1 million cycles. Fatigue limits were determined from trend lines. Kaplan–Meier survival analysis was performed to determine the failure stress at the median percentile survival level for 1 million of cycles before and after sandblasting. The statistical analyses used the log-rank test. Characterization of the critical flaw was performed by SEM for the majority of the failed specimens. Results The fatigue limits “as received” (ctr) were: LV = 720 MPa, LVB = 600 MPa, KV = 560 MPa, ZW = 470 MPa. The fatigue limits “after CoJet sandblasting” were: LV = 840 MPa, LVB = 788 MPa, KV = 645 MPa, ZW = 540 MPa. The increase in fatigue limit after sandblasting was 15% for Zeno (ZW) and Everest (KV), 17% for Lava (LV) and 31% for Lava colored (LVB). The KM median survival stresses in MPa were: ZW(ctr) = 549 (543–555), ZW(s) = 587 (545–629), KV(ctr) = 593 (579–607), KV(s) = 676 (655–697), LVB(ctr) = 635 (578–692), LVB(s) = 809 (787–831), LV(ctr) = 743 (729–757), LV(s) = 908 (840–976). Log-rank tests were significantly different (p < 0.001) for all sandblasted groups vs. the “as received” except for Zeno (Wieland) (p = 0.295). Failures started from both intrinsic and machined flaws. Significance 30 µm particle sandblasting did significantly improve the fatigue behavior of three out of four Y-TZP ceramic materials and can therefore be recommended for adhesive cementation procedures. This study was supported in part by grants from the Swiss Society for Reconstructive Dentistry (SSRD) and 3M Espe.

Tolerant low-loss three-lens coupling system for 1.48-um unstable-cavity lasers  

NASA Astrophysics Data System (ADS)

A 1.48-micrometer unstable-cavity laser is coupled into a single-mode fiber using three microlenses. Reproducible coupling of very high power is demonstrated with different types of lenses (plano-convex or bi-convex, with different apertures). Over 550 mW in single-mode fiber were reproducibly reached; to our knowledge, it is the highest power coupled into a single-mode fiber from a single semiconductor laser at this wavelength. Tolerance measurements on all of the coupling elements of a three-lens system are reported for the first time; an unexpected very large tolerance on the axial displacement of the second lens was measured. Results and interpretation with the aid of Gaussian and aberration simulations are also presented. Finally, we report on the first realization of a module with 46% chip to fiber coupling efficiency.

High resolution analysis of the ethylene-1-13C spectrum in the 8.4-14.3 um region  

SciTech Connect

Fourier transform spectra of mono-13C ethylene have been recorded in the 8.4-14.3- ?m spectral region (700 cm-1 to 1190 cm-1) using a Bruker 120 HR interferometer at a resolution of 0.0017 cm-1 allowing the extensive study of the set of resonating states {101, 81, 71,41,61}. Due to the high resolution available as well as the extended spectral range involved in this study, a much larger set of line assignments are now available. The present analysis has leads to the determination of more accurate spectroscopic constants including interaction constants than were obtained in earlier studies. In particular, the following band centers were derived: ?0(?10) = 825.40602(30) cm-1, ?0(?8) = 932.19572(15) cm-1, ?0(?7) = 937.44452(10) cm-1, ?0(?4) = 1025.6976(14) cm-1. Finally a synthetic spectrum was generated leading to the assignment of a number of 13C12CH4 lines observed through an earlier heterodyne spectroscopic study.

Diffraction properties of a 0.24-um period multilayer laminar amplitude grating in the soft x-ray region  

NASA Astrophysics Data System (ADS)

We report on the fabrication of a laminar multilayer amplitude grating, characterization in the soft x-ray region, and modeling of its properties. Holographic lithography was used to produce a 0.24-micrometers spatial period grating on a triode sputtered Mo/C multilayer mirror. The pattern was transferred into the multilayer mirror by reactive ion etching in an SF6 plasma after an intermediate lift-off step. The position and relative efficiency of the different orders of a grating etched down to the silicon substrate were measured at the Cu L(alpha (beta) ) line (1.33 nm). The results were interpreted in the framework of a scalar kinematic diffraction theory.

Determinação de elementos próprios dos asteróides troianos: comparação entre as teorias semi-analítica e sintética  

NASA Astrophysics Data System (ADS)

Além do cálculo semi-analítico de elementos próprios dos asteróides Troianos (Beaugé & Roig 2001, Icarus 153, 391), recentemente foi apresentado um novo conjunto destes elementos próprios determinado através de uma teoria sintética (Knenezevic & Milani 2003, comunicação pessoal). As bases de dados contendo estas determinações estão disponiveis na pagina web do Asteroid Dynamical Site (http://hamilton.dm.unipi.it/cgi-bin/astdys/astibo). Nesta comunicação apresentamos os primeiros resultados de um estudo comparativo entre ambos conjuntos de elementos próprios, analisando suas vantagens e desvantagens, assim como os limites de precisão de cada conjunto. Mostramos que os elementos próprios sintéticos são mais precisos que os smi-analíticos para grandes amplitudes de libração do ângulo s = l-lJup, embora acontece o contrario para os corpos cuja amplitude de libração é muito pequena. Finalmente discutimos a influencia destes erros na determinação de familias de asteroides e da estrutura resonante em torno dos pontos Lagrangeanos L4 e L5.

A distância e o conteúdo estelar da região HII gigante G333.1-0.4 - vínculos para a taxa de formação estelar da galáxia  

NASA Astrophysics Data System (ADS)

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

Análise cinemática bi-dimensional dos núcleos de NGC 4051 e NGC 4941  

NASA Astrophysics Data System (ADS)

Estudos recentes da cinemática da região dentro de 1 kpc do núcleo de galaxias Seyfert próximas usando espectroscopia de fenda longa com alta resolução espacial (~ 100 pc ou melhores) encontraram uma queda na dispersão de velocidades nas regiões centrais dentro de um raio de ~ 300 pc do núcleo. Essa queda vem sendo tentativamente explicada por um cenário evolutivo em que um evento de formação estelar recente cria as estrelas da região central em um disco de dimensões 300 pc. Desde sua criação, tais estrelas não tiveram tempo de "virializar", ou seja, seguir a distribuição radial de dispersões de velocidades determinada pelo campo gavitacional da galáxia e, portanto, a dispersão de velocidades medida nessa região do bojo acaba sendo menor do que a dispersão medida nas vizinhanças. No presente trabalho investigamos a cinemática estelar no núcleo das galáxias Seyfert NGC 4051 e NGC 4941 usando o tripleto do Ca ii (8500 Å) em absorção. Os dados foram obtidos com o IFU GMOS no telescópio Gemini. O elemento de resolução espacial nas galáxias é da ordem de 30 pc. No intervalo espectral coberto pelo espectrografo a linha [S iii] (9068 Å) também é visível, o que permite estudar a cinemática do gás na mesma região. Serão apresentados mapas bi-dimensionais da velocidade e dispersão de velocidades das estrelas e do gás, além de imagens na linha [S iii] que mapeia o gás de alta excitação.

Flutuações da temperatura eletrônica em NGC 2438 e NGC 2440  

NASA Astrophysics Data System (ADS)

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

Uma comparação entre técnicas de propagação de erros em astrofísica: Monte Carlo x Bootstrap  

NASA Astrophysics Data System (ADS)

Recentemente Dhillon & Watson (2001) criticaram o procedimento de determinação de erros via simulações de Monte Carlo no caso do imageamento indireto de estrelas, por introduzir ruído nos dados e resultar em erros superestimados. Estes autores propuseram a utilização alternativa do método de Bootstrap como uma técnica superior para a estimativa de erros. Neste trabalho apresentamos os resultados de um estudo comparativo da performance das técnicas de simulação por Monte Carlo e por Bootstrap para a determinação de erros em duas situações de interesse: (i) ajuste de modelos a espectros observados e (ii) imageamento indireto de discos de acréscimo com técnicas de mapeamento por eclipse. No caso (i), os dados de entrada são espectros de emissão simples de hidrogênio aos quais é adicionado ruído gaussiano de amplitude selecionada. No caso (ii), são produzidas curvas de luz do eclipse de uma distribuição de brilho seguindo a lei TµR-3/4 para discos estacionários cuja taxa de acréscimo varia ao longo do eclipse segundo uma distribuição gaussiana de amplitude selecionada, simulando o ruído. A avaliação da performance é feita com o auxílio de um diagrama do erro relativo na grandeza ajustada, conforme obtido por cada método, versus o erro relativo (ruído/sinal) dos dados de entrada. O estudo mostra que as duas técnicas produzem resultados semelhantes nos dois casos, e que a suposta superioridade do método de Bootstrap não se confirma.

Nebulosas planetárias galácticas: idades e cinemática  

NASA Astrophysics Data System (ADS)

As nebulosas planetárias são formadas a partir de estrelas com massas entre 0.8 e 8 massas solares na sequência principal, formando um conjunto de objetos com idades e populações diferentes. Esse fato torna as nebulosas interessantes ao estudo da rotação galáctica, uma vez que as populações mais jovens devem estar claramente associadas ao disco fino da Galáxia, enquanto que as populações mais velhas estariam associadas ao disco espesso ou mesmo ao halo galáctico. Neste trabalho, utilizamos uma grande amostra de nebulosas com velocidades radiais conhecidas para determinar a curva de rotação da Galáxia. Para minimizar os erros decorrentes das incertezas nas distâncias, usamos quatro diferentes escalas estatísticas. Para a atribuição da idade dos objetos, utilizamos o método proposto recentemente por Maciel et al. (Astron. Astrophys. 397, 667, 2003), em um estudo da variação temporal dos gradientes de abundâncias. Com esse método, é possível obter uma classificação das nebulosas por grupos de idade, totalmente independente de outros sistemas de classificação, uma vez que as idades são estimadas individualmente, a partir das metalicidades das nebulosas. Nossos resultados são comparados com as previsões dos tipos de Peimbert, e mostram que os desvios médios das curvas obtidas são sensivelmente menores nos casos dos objetos mais jovens, associados ao disco fino, com relação aos objetos mais velhos do disco espesso, levando à determinação de uma curva de rotação semelhante à dos objetos de população I jovem.

Abundância química de simbióticas na direção do bojo galáctico  

NASA Astrophysics Data System (ADS)

O estudo da distribuição de metalicidades de gigantes K no Bojo indica um largo intervalo com valores entre 0.1 a 10 vezes o valor solar. As razões elementais Ca/Fe, Si/Fe, Mg/Fe são típicas de estrelas do halo, apontando para um processo rápido de enriquecimento, via estrelas masssivas (SN's tipo II). No entanto, este cenário não combina com os resultados derivados de nebulosas planetárias do bojo tais como os de Ratag et al. (1992, A&A,255,270), Cuisinier et al.(2000, A&A,353, 543), Escudero e Costa (2001, A&A,380, 300),que obtêm abundâncias análogas às do disco. Neste cenário, o estudo de estrelas simbióticas possibilita uma abordagem particularmente apropriada para o problema das abundâncias químicas de estrelas de massa intermediária em estágios avançados da evoluçao estelar. Apresentamos aqui os resultados da determinacão das abundâncias do grupo do CNO numa extensa amostra de simbióticas do bojo. Aliás, com a disponibilidade de espectros no visível determinamos também abundâncias de Ar, Ne, S e He, fundamentais para analisar os processos de enriquecimento químico ocorridos ao longo da evolução estelar, bem como a evolução química do meio interestelar. Com os espectros UV do satelite IUE obtivemos abundâncias de C, necessárias no estudo da evolução dos sistemas. As relaçoes C/N-O/N mostram que o material nebular é produto do vento da componente gigante e não dos eventos de nova que às vezes acontecem nestes sistemas, como foi mostrado por Nussbaumer et al (1988,A&A,198,179). As abundâncias de Ar, S, Ne e O são compativeis com resultados de fontes no disco e bojo, seguindo o gradiente proposto por muitos autores na literatura a partir de diferentes objetos como cefeidas, nebulosas planetárias e anãs G.

Evolução rotacional de corpos reacumulados  

NASA Astrophysics Data System (ADS)

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.

Laser tissue melding: use of 1.32-um computerized Nd:YAG laser, results of leak/burst strength studies in microsurgical procedures  

NASA Astrophysics Data System (ADS)

The ProClosureTM System (PCS) consists of a low power 1.32micrometers Nd:YAG laser coupled to a handheld disposable fiber optic device. The system has been designed to perform a wide range of tissue welding applications such as cosmetic skin closure,vascular surgery, and minimally invasive surgical procedures normally performed with sutures and staples. Utilizing a wavelength for tissue fusion that is least distracted by medium in the surgical field coupled with a computerized delivery system allows for a more precise application (+/- 5%) of laser energy to the tissue. The study design involved the micro-surgical anastomosis of twenty Sprague-Dawley rats (vas deferens) and twenty-one Sprague-Dawley rats (femoral arteries). Each rat is its own contralateral control. Laser repair time is approximately one-third that of conventional suturing. Postoperative dissection and burst strength testing was conducted at day 0, 1, 7, and 14. At each postoperative interval, the mean leak/burst strength for laser-assisted closure v. control, was markedly higher. The precise application of energy fluence resulting from ProClosure's computerized system yields an initial strength and a fluid static seal that is superior to conventional suture closure.

Investigation of pulsed 1.44 um Nd:YAG laser in nasal and sinus surgery: in vitro and in vivo animal study  

NASA Astrophysics Data System (ADS)

The Nd:YAG laser 1.44 micrometers wavelength is a relatively new wavelength with water absorption coefficient higher even than 1.06 micrometers , permitting the creation of a more precise lesion with less damage to surrounding tissue. Very little, however, is known about its effects in live experimental model. The non-contact 1.44 micrometers Nd:YAG laser was used in four animals (dogs) to perform a resection of middle turbinate and to create a 1 cm lesion on the septal mucosa and inferior turbinate in the left side through a sinuscope. The same procedure was performed on the opposite side using microsurgical forceps as a control. The animals were followed-up, examined endoscopically, and sacrificed after 48 hours (1 animal), 1 month (1 animal) and 2 months (2 animals). Moderate-to-severe bleeding was commonly encountered on the control side, which obscured vision, and required packing in 2 dogs. In contrast, the laser had a satisfactory hemostatic result with easy control for endoscopic resection. Normal healing was observed under gross and by histologic examination 48 hours and 1 month after the surgery and healing was complete by 2 months. There was more scaring and adhesions produced by the forceps on the control side. Histologically, tissue thermal damage produced by the laser was superficial and confined to the lesion. The epithelial regeneration has been nearly completed in 1 month, with normal mucosa coverage in 2 months after the surgery. This study suggests that the 1.44 micrometers wavelength of the Nd:YAG should be considered as safe and reliable for intranasal application.

In Situ Measurements of H 2 O From a Stratospheric Balloon by Diode Laser Direct-Differential Absorption Spectroscopy at 1.39 um  

NASA Astrophysics Data System (ADS)

A distributed-feedback InGaAs laser diode emitting near 1.393 m is used in conjunction with an optical multipass cell that is open to the atmosphere to yield ambient water-vapor measurements by infrared absorption spectroscopy. To obtain the high dynamic range for the measurements that is required for continuous water-vapor monitoring in the upper troposphere and the lower stratosphere, we used a simple circuit that combined differential and direct detection. Furthermore, the laser emission wavelength was tuned to balance the steep decrease in H2 O concentration with altitude by sweeping molecular transitions of stronger line strengths. The technique was implemented by use of the Spectrom tre Diodes Laser Accordables (SDLA), a tunable diode laser spectrometer operated from a stratospheric balloon. Absorption spectra of H2 O in the 5 -30-km altitude range obtained at 1-s intervals during recent balloon flights are reported. Water-vapor mixing ratios were retrieved from the absorption spectra by a fit to the full molecular line shape in conjunction with in situ pressure and temperature measurements, with a precision error ranging from 5% to 10%.

High-Efficiency On-Line Solid-Phase Extraction Coupling to 15-150 um I.D. Column Liquid Chromatography for Proteomic Analysis  

SciTech Connect

Flexible manipulation of various properties of proteomic samples is important for proteomic analyses, but it has been little explored for newly developed approaches based on liquid chromatography (LC) in combination with mass spectrometry (MS). With miniaturization of the LC column inner diameter dimensions (required for improving the analysis sensitivity), this issue becomes more challenging due to the small flow rates and the increasing effects of extra column volume on the separation quality and its use for resolving complex proteomic mixtures. In this study, we used commercial switching valves (150-mm channels) to implement the on-line coupling of capillary LC columns with relatively large solid phase extraction (SPE) columns operated at 10,000 psi. With optimized column connections, switching modes, and SPE column dimensions, high-efficiency on-line SPE-capillary and nanoscale LC separations were obtained with peak capacities of~1000 for capillaries having inner diameters between 15 to 150 mm. The on-line coupled SPE columns increased the sample processing capabilities by~400-fold for sample solution volume and~10-fold for sample mass. The proteomic applications of this on-line SPE-capillary LC system were evaluated for analysis of both soluble and membrane protein tryptic digests. Used with an ion trap tandem MS we could typically identify 1100-1500 peptides for analyses in a single 5-hour run. Peptides extracted on the SPE column and eluted from the LC column covered a hydrophilicity/hydrophobicity range that include an estimated~98% of all the tryptic peptides. The present implementation also facilitates automation and enables use of both disposable SPE columns and electrospray emitters, providing a robust basis for routine proteomic analyses.

Application of top-down CD-SEM metrology in measuring wafers with resist film thickness of 24 um with various sidewall profiles  

NASA Astrophysics Data System (ADS)

An automated top-down CD-SEM technique, complimenting the existing high angle tilt SEM method has been developed for measuring features printed at a film thickness of 24 microns. Measurements of resist linewidth versus exposure dose were made using a KLA 8100 top-down CD-SEM. The advantage of this CD-SEM is the automated collection of a large statistical pool of data and the ability to determine the linewidth independently of operator, accurately and consistently. The technique has been applied to AZ P4000 and AZ 9000 photoresist thick films through and beyond their exposure latitude. Maintaining a sharp sidewall profile of photoresist while supporting high aspect ratios is ideal for magneto-resistive and inductive thin film recording head coil plating and many other mission-critical applications. Also a fast and non-destructive thin film recording head coil plating and many other mission-critical applications. Also a fast and non-destructive metrology technique is desired and preferred to support future more costly and larger substrates. Results are reported for 10 and 6 micron reticle linesizes, respectively, at a film thickness of 24 microns using the AZ P4620 and AZ 9262 positive photoresist over bare silicon wafers. Wafers were exposed using an Ultratech Ultrastep Stepper model 1500 system and then developed by AZ 400 K inorganic developer. Exposure dose- array fields were measured first on the top-down KLA CD-SEM and then coated and re-measured on a Hitachi scanning electron microscope with 60 degrees-tilt capability. The importance of knowledge of resist profile and choosing the proper metrology tool is discussed. Linewidth values were compared with result from the standard tilt microscope reading method. Agreement to within 10 percent is noted for profiles corresponding to most exposure doses. Profiles for higher, over-exposed fields resemble a 'coke bottle' and linewidth for bottom of resist is inferred by extrapolation based on the prior correlation found between the two SEMs. The AZ 9262 resist line features showed a smaller 'coke bottle' profile at higher doses than AZ P4620 line features. Further work is planned for other positive resists with non- traditional profiles on unconventional substrates.

Confusion about a little observatory: the history of the first high school observatory (German Title: Verwirrung um eine kleine Sternwarte: Die Geschichte der ersten Chemnitzer Schulsternwarte )  

NASA Astrophysics Data System (ADS)

By means of a small watercolor, painted by a musicologist, the existence of the highschool observatory of Chemnitz was rediscovered. The small observatory was build in 1893 by means of funds and a donation: after WW I it was also used for popular education. During Nazi times, the observatory fell into neglect, and the mechanical damage made it impossible to put it back into operation after WW II The building was torn down in 1964 and forgotten.

Thulium:YAG VapoEnucleation of the prostate in large glands: a prospective comparison using 70- and 120-W 2-um lasers  

PubMed Central

This study compared the efficacy of 70- and 120-w 2-µm thulium:YAG VapoEnucleation of the prostate (ThuVEP) for patients with benign prostatic obstruction (BPO). A prospective analysis of 84 patients with symptomatic BPO and prostatic enlargement (?60 ml) who underwent either 70-w (n=44) or 120-w ThuVEP (n=40) non-randomly was carried out. Patient demographics and perioperative and 12-month follow-up data were analysed. The mean prostate volume was 79.90±27.49 ml in patients who had received 70-w ThuVEP, which was less than in those who had received 120-w ThuVEP (88.53±25.10; P=0.033). The mean enucleation (resected weight/laser time, 2.16±1.21 g min?1 vs. 1.23±0.60 g min?1; P=0.013), operation efficiency (resected weight/total operation time, 0.76±0.35 g min?1 vs. 0.42±0.27 g min?1; P=0.000) and percentage of resected tissue (66.93%±22.79% vs. 45.41%±23.33% P=0.000) were higher with 120-w treatment compared to 70-w ThuVEP. One patient (1.2% of total patients) (in the 120-w group) required a blood transfusion postoperatively. Sixty-one patients (73%) were available for review at the 12-month follow-up time point. The quality of life (QoL), International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), postvoiding residual urine (PVR) and prostate volume improved significantly after treatment (P?0.035) and were not significantly different between those treated with the different devices (70- and 120-w). The median prostate volume reduction was 81.70% and 82.19% with 70- and 120-w ThuVEP, respectively. The incidence of complications was low and did not differ between groups treated with the different devices. Two patients (2.4%) (one per group) had a bladder neck contracture at the follow-up. ThuVEP is a safe and efficacious procedure for the treatment of symptomatic BPO. The incidence of complications was low with both devices. The 120-w thulium:YAG device enhances the effectiveness of ThuVEP with regard to the percentage of resected tissue and the enucleation/operation efficiency.

3-12-um images of HD44179 and M42: spectral differencing as a mid-infrared astronomical image enhancement technique  

NASA Astrophysics Data System (ADS)

NASA Ames Research Center and Lick Observatory have jointly developed two prototype infrared camera for astronomical imaging. The new cameras have been built using Amber Engineering Inc. 128 X 128 SiGa and InSb focal plane arrays. We report observations of the BN-KL source complex in M42 and HD44179 which are used as a demonstration of the cameras' performance when used as narrow band spectral images. The images have a dynamic range in excess of 10(superscript 3). The high signal to noise ratio and linearity of the images are used to demonstrate the power of spectral differencing as a tool for astronomical image enhancement at mid infrared wavelengths. The observations were made over a range of wavelengths 3.1 - 3.3 micrometers and 8.4 - 11.5 microns in and out of the silicate absorption band, and in the PAH emission bands at 3.3 micrometers and 11.3 micrometers using approximately 2% spectral resolution. Bell and Crisp, 1991, have reported spatial resolution enhancement of images for the surface of Mars by division of multispectral images in and out of the H(subscript 2)O absorption feature at 3 micrometers . We find that a similar image processing technique using normalized image differencing can be used in the 10 micrometers silicate absorption feature and PAH emission bands to improve the contrast in mid-infrared astronomical images. This technique is expected to be applicable to imaging of galactic nuclei and other astronomical objects as well as embedded stellar infrared sources.

Acid-breakable-resin-based chemical amplification positive resist for 0.1-um-rule reticle fabrication: design and lithographic performance  

NASA Astrophysics Data System (ADS)

We have designed a new chemical amplification (CA) positive resist for 0.1micrometers reticle fabrication. This positive resist consists of an acid-generator, an acid-diffusion controller, and an acid-breakable (AB) resin that can be converted to initial polyphenol units by an acid-catalyzed reaction. In the exposed region, main-chain scission of the AB resin matrix produces nearly mono-dispersed fragments (the polyphenol). This complete fragmentation results in an extremely high dissolution rate with an aqueous-base developer (tetramethylammonium hydroxide: 2.38 wt%). The AB resin-based resist enabled fabrication of scum free 0.15micrometers line-and-space patterns on a CrOx plate by using a 50-kV electron-beam reticle writer (HL series). The line- edge roughness of patterns delineated by this resist (<10 nm) was less than half that for previously developed novolak-resin-based CA resists (RE series:>30nm).
