Optical/NIR stellar absorption and emission-line indices from luminous infrared galaxies

We analyze a set of optical-to-near-infrared long-slit nuclear spectra of 16 infrared-luminous spiral galaxies. All of the studied sources present H$_2$ emission, which reflects the star-forming nature of our sample, and they clearly display H I emission lines in the optical. Their continua contain many strong stellar absorption lines, with the most common features due to Ca I, Ca II, Fe I, Na I, Mg I, in addition to prominent absorption bands of TiO, VO, ZrO, CN and CO. We report a homogeneous set of equivalent width (EW) measurements for 45 indices, from optical to NIR species for the 16 star-forming galaxies as well as for 19 early type galaxies where we collected the data from the literature. This selected set of emission and absorption-feature measurements can be used to test predictions of the forthcoming generations of stellar population models. We find correlations among the different absorption features and propose here correlations between optical and NIR indices, as well as among different NIR indices, and compare them with model predictions. While for the optical absorption features the models consistently agree with the observations,the NIR indices are much harder to interpret. For early-type spirals the measurements agree roughly with the models, while for star-forming objects they fail to predict the strengths of these indices.Comment: accepted for publication in MNRA

Gemini NIFS survey of feeding and feedback in nearby active galaxies III. Ionized versus warm molecular gas masses and distributions

We have used the Gemini Near-Infrared Integral Field Spectrograph in the J and K bands to map the distribution, excitation, and kinematics of the ionized H ii and warm molecular gas H2, in the inner few 100 pc of six nearby active galaxies: NGC 788, Mrk 607, NGC 3227, NGC 3516, NGC 5506, NGC 5899. For most galaxies, this is the first time that such maps have been obtained. The ionized and H2 gas show distinct kinematics: while the H2 gas is mostly rotating in the galaxy plane with low velocity dispersion (σ), the ionized gas usually shows signatures of outflows associated with higher σ values, most clearly seen in the [Fe ii] emission line. These two gas species also present distinct flux distributions: the H2 is more uniformly spread over the whole galaxy plane, while the ionized gas is more concentrated around the nucleus and/or collimated along the ionization axis of its active galactic nucleus (AGN), presenting a steeper gradient in the average surface mass density profile than the H2 gas. The total H ii masses cover the range 2×105--2×107 M⊙, with surface mass densities in the range 3–150 M⊙ pc−2, while for the warm H2 the values are 103–4 times lower. We estimate that the available gas reservoir is at least ≈ 100 times more massive than needed to power the AGN. If this gas forms new stars the star formation rates, obtained from the Kennicutt–Schmidt scaling relation, are in the range 1–260 × 10−3 M⊙ yr−1. But the gas will also – at least in part – be ejected as the observed outflow

Vínculo entre profesional y enfermo en el tratamiento de la tuberculosis: desempeño de la atención básica en un municipio del estado de Sao Paulo

This study evaluated the performance of health care services implementing TB control actions in relation to the establishment of bonds between health professionals and patients in São José do Rio Preto, SP, Brazil from the perspective of patients, health professionals, and managers. A total of 108 patients, 37 health professionals and 15 managers were interviewed through a questionnaire containing 10 indicators of bond-establishment based on the instruments of the Primary Care Assessment Tool, adapted to evaluate tuberculosis control in Brazil. The three groups of actors considered the establishment of bonds satisfactory, though opinions of patients and managers differed in almost all indicators. This fact indicates that the view of managers is still predominantly focused on bureaucratic and administrative aspects, which shows the need for managers to integrate more management and care actions.O objetivo do estudo foi avaliar o desempenho dos serviços de saúde que realizam ações de controle da tuberculose (TB), relacionado ao vínculo entre o profissional e o doente, no município de São José do Rio Preto, SP, na percepção de doentes, profissionais de saúde e gestores. Foram entrevistados 108 doentes, 37 profissionais e 15 gestores, utilizando questionário elaborado com 10 indicadores para a dimensão vínculo, construídos com base no Primary Care Assessment Tool, adaptado para avaliar a atenção à tuberculose no Brasil. O vínculo foi avaliado como satisfatório pelos três atores, entretanto, houve variabilidade entre as opiniões dos doentes e os gestores em quase todos os indicadores, o que permite inferir que a visão dos gestores ainda é voltada predominantemente aos aspectos burocráticos e administrativos, necessitando que esses integrem mais as ações gerenciais e assistenciais.El objetivo del estudio fue evaluar el desempeño de los servicios de salud que realizan acciones de control de la TB relacionado al vínculo entre el profesional y el enfermo, en el municipio de Sao José del Rio Preto, en Sao Paulo, en la percepción de enfermos, profesionales de la salud y gestores.

Viabilidade do processamento de biscoitos com farinha de pinhãoViability of cookie-processing with Paraná pine nut flour

O pinhão é a semente do pinho ou pinheiro-do-paraná (Araucaria angustifolia) de grande ocorrência no estado do Paraná. A farinha obtida é uma fonte de proteína, carboidratos e fibras e sua aplicação na indústria de alimentos poderia contribuir para melhorar o valor nutricional de vários produtos. Biscoito é o produto obtido pelo amassamento e cozimento de massa preparada com farinhas, amidos, fermentada ou não e outras substâncias alimentícias. Neste trabalho, foi estudada a elaboração de biscoito com farinha de pinhão. Foram preparadas três formulações, variando-se a adição da farinha de pinhão na formulação básica de biscoito. As amostras de biscoito com formulações de 0, 5, 10 e 20% foram submetidas a teste de aceitação. As três formulações foram bem aceitas, apresentando uma consistência semelhante ao padrão.Abstract The seed from the evergreen species Paraná Pine (Araucaria angustifolia), which is found in Paraná State, is called “pinhão”. The “pinhão” flour is asource of protein, carbohydrates and fiber, so that its use in food industries may improve the nutritional value of several products. Cookies are made of a pastry prepared with flour, starch, with or without fermentation, and other ingredients. This research studied the production of biscuits with 5, 10 and 20% of “pinhão” flour. These three formulations were well accepted by subjects who participated in a tasting test and their texture was similar to standard cookies

Gemini NIFS survey of feeding and feedback in nearby active galaxies : IV. Excitation

The near-infrared spectra of active galactic nuclei (AGN) present emission lines of different atomic and molecular species. The mechanisms involved in the origin of these emission lines in AGN are still not fully understood. We use J- and K-band integral field spectra of six luminous (43.1 < logLbol/(erg s−1) < 44.4) Seyfert galaxies (NGC 788, Mrk 607, NGC 3227, NGC 3516, NGC 5506, and NGC 5899) in the local Universe (0.0039 <z< 0.0136) to investigate the gas excitation within the inner 100–300 pc radius of the galaxies at spatial resolutions of a few tens of parsecs. In all galaxies, the H2 emission originates from thermal processes with excitation temperatures in the range 2400–5200 K. In the high-line ratio (HLR) region of the H2/Brγ versus [Fe II]/Paβ diagnostic diagram, which includes 29 per cent of the spaxels, shocks are the main excitation mechanism, as indicated by the correlation between the line widths and line ratios. In the AGN region of the diagram (64 per cent of the spaxels) the H2 emission is due to the AGN radiation. The [Fe II] emission is produced by a combination of photoionization by the AGN radiation and shocks in five galaxies and is dominated by photoionization in NGC 788. The [S IX]1.2523 μm coronal emission line is present in all galaxies, and its flux distributions are extended from 80 to 185 pc from the galaxy nuclei, except for NGC 5899, in which this line is detected only in the integrated spectrum

Generation of an induced pluripotent stem cell line (EURACi005-A) from a Parkinson's disease patient carrying a homozygous exon 3 deletion in the PRKNgene

Abstract Mutations in the PRKN gene, encoding parkin, are the most frequent known cause of recessive Parkinson's disease (PD). We report the generation of an induced pluripotent stem cell (iPSC) line of a patient carrying a homozygous deletion of exon 3 in the PRKN gene. Skin fibroblasts were reprogrammed using non-integrating episomal plasmids. The generated cell line (EURACi005-A; iPS-2011) exhibits expression of pluripotency markers, the potential to differentiate into all three germ layers, and a stable karyotype. This iPSC line provides a valuable resource for further research on the pathomechanism and drug testing for PRKN-linked PD

Gemini NIFS survey of feeding and feedback in nearby active galaxies V. Molecular and ionized gas kinematics

We study the gas distribution and kinematics of the inner kpc of six moderately luminous (43.43 ≤ log Lbol ≤ 44.83) nearby (0.004 ≤ z ≤ 0.014) Seyfert galaxies observed with the Near-infrared Integral Field Spectrograph (NIFS) in the J (⁠1.25μm) and K (⁠2.2μm) bands. We analyse the most intense emission lines detected on these spectral wavebands: [Fe ii] 1.2570μm and Paβ, which trace the ionized gas in the partially and fully ionized regions, and H2 2.1218μm, which traces the hot (∼2000 K) molecular gas. The dominant kinematic component is rotation in the disc of the galaxies, except for the ionized gas in NGC 5899 that shows only weak signatures of a disc component. We find ionized gas outflow in four galaxies, while signatures of H2 outflows are seen in three galaxies. The ionized gas outflows display velocities of a few hundred km s−1, and their mass outflow rates are in the range 0.005–12.49 M⊙ yr−1. Their kinetic powers correspond to 0.005–0.7 per cent of the active galactic nuclei (AGN) bolometric luminosities. Besides rotation and outflows signatures in some cases, the H2 kinematics also reveals inflows in three galaxies. The inflow velocities are 50–80 km s−1 and the mass inflow rates are in the range 1–9 × 10−4 M⊙ yr−1 for hot molecular gas. These inflows might be only the hot skin of the total inflowing gas, which is expected to be dominated by colder gas. The mass inflow rates are lower than the current accretion rates to the AGN, and the ionized outflows are apparently disturbing the gas in the inner kpc

Gemini NIFS survey of feeding and feedback processes in nearby active galaxies : VI. Stellar populations

We use Gemini Near-Infrared Integral Field Spectrograph (NIFS) adaptive optics assisted data cubes to map the stellar population of the inner few hundred parsec of a sample of 18 nearby Seyfert galaxies. The near-infrared light is dominated by the contribution of young to intermediate-age stellar populations, with light-weighted mean ages ‹t›L ≲ 1.5 Gyr. Hot dust (HD) emission is centrally peaked (in the unresolved nucleus), but it is also needed to reproduce the continuum beyond the nucleus in nearly half of the sample. We have analysed the stellar population properties of the nuclear region and their relation with more global properties of the galaxies. We find a correlation between the X-ray luminosity and the contributions from the HD, featureless continuum (FC), and reddening AV. We attribute these correlations to the fact that all these properties are linked to the mass accretion rate to the active galactic nuclei (AGNs). We also find a correlation of the bolometric luminosity log(LBolobs) with the mass-weighted mean age of the stellar population, interpreted as due a delay between the formation of new stars and the triggering/feeding of the AGN. The gas reaching the supermassive black hole is probably originated from mass loss from the already somewhat evolved intermediate-age stellar population (‹t›L ≲ 1.5 Gyr). In summary, our results show that there is a significant fraction of young to intermediate-age stellar populations in the inner few 100 pc of active galaxies, suggesting that this region is facing a rejuvenation process in which the AGN, once triggered, precludes further star formation, in the sense that it can be associated with the lack of new star formation in the nuclear region
