The Cariris Velhos tectonic event in Northeast Brazil  

NASA Astrophysics Data System (ADS)

The Borborema Province in northeastern South America is a typical Brasiliano-Pan-African branching system of Neoproterozoic orogens that forms part of the Western Gondwana assembly. The province is positioned between the So Luis-West Africa craton to the north and the So Francisco (Congo-Kasai) craton to the south. For this province the main characteristics are (a) its subdivision into five major tectonic domains, bounded mostly by long shear zones, as follows: Mdio Corea, Cear Central, Rio Grande do Norte, Transversal, and Southern; (b) the alternation of supracrustal belts with reworked basement inliers (Archean nuclei + Paleoproterozoic belts); and (c) the diversity of granitic plutonism, from Neoproterozoic to Early Cambrian ages, that affect supracrustal rocks as well as basement inliers. Recently, orogenic rock assemblages of early Tonian (1000-920 Ma) orogenic evolution have been recognized, which are restricted to the Transversal and Southern domains of the Province. Within the Transversal Zone, the Alto Paje terrane locally includes some remnants of oceanic crust along with island arc and continental arc rock assemblages, but the dominant supracrustal rocks are mature and immature pelitic metasedimentary and metavolcaniclastic rocks. Contiguous and parallel to the Alto Paje terrane, the Riacho Gravat subterrane consists mainly of low-grade metamorphic successions of metarhythmites, some of which are clearly turbiditic in origin, metaconglomerates, and sporadic marbles, along with interbedded metarhyolitic and metadacitic volcanic or metavolcaniclastic rocks. Both terrane and subterrane are cut by syn-contractional intrusive sheets of dominantly peraluminous high-K calc-alkaline, granititic to granodioritic metaplutonic rocks. The geochemical patterns of both supracrustal and intrusive rocks show similarities with associations of mature continental arc volcano-sedimentary sequences, but some subordinate intra-plate characteristics are also found. In both the Alto Paje and Riacho Gravat terranes, TIMS and SHRIMP U-Pb isotopic data from zircons from both metavolcanic and metaplutonic rocks yield ages between 1.0 and 0.92 Ga, which define the time span for an event of orogenic character, the Cariris Velhos event. Less extensive occurrences of rocks of Cariris Velhos age are recognized mainly in the southernmost domains of the Province, as for example in the Poo Redondo-Maranc terrane, where arc-affinity migmatite-granitic and meta-volcano-sedimentary rocks show U-Pb ages (SHRIMP data) around 0.98-0.97 Ga. For all these domains, Sm-Nd data exhibit TDM model ages between 1.9 and 1.1 Ga with corresponding slightly negative to slightly positive ?Nd( t) values. These domains, along with the Borborema Province as a whole, were significantly affected by tectonic and magmatic events of the Brasiliano Cycle (0.7-0.5 Ga), so that it is possible that there are some other early Tonian rock assemblages which were completely masked and hidden by these later Brasiliano events. Cariris Velhos processes are younger than the majority of orogenic systems at the end of Mesoproterozoic Era and beginning of Neoproterozoic throughout the world, e.g. Irumide belt, Kibaride belt and Namaqua-Natal belt, and considerably younger than those of the youngest orogenic process (Ottawan) in the Grenvillian System. Therefore, they were probably not associated with the proposed assembly of Rodinia. We suggest, instead, that Cariris Velhos magmatism and tectonism could have been related to a continental margin magmatic arc, with possible back-arc associations, and that this margin may have been a short-lived (<100 m.y.) leading edge of the newly assembled Rodinia supercontinent.

Brazilian mosquito (Diptera: Culicidae) fauna: I. Anopheles species from Porto Velho, Rondnia state, western Amazon, Brazil.  

PubMed

This study contributes to knowledge of Anopheles species, including vectors of Plasmodium from the western Brazilian Amazon in Porto Velho, Rondnia State. The sampling area has undergone substantial environmental changes as a consequence of agricultural and hydroelectric projects, which have caused intensive deforestation and favored habitats for some mosquito species. The purpose of this study was to diagnose the occurrence of anopheline species from collections in three locations along an electric-power transmission line. Each locality was sampled three times from 2010 to 2011. The principal adult mosquitoes captured in Shannon trap were Anopheles darlingi, An. triannulatus, An. nuneztovari l.s., An.gilesi and An. costai. In addition, larvae were collected in ground breeding sites for Anopheles braziliensis, An. triannulatus, An. darlingi, An. deaneorum, An. marajoara, An. peryassui, An. nuneztovari l.s. and An. oswaldoi-konderi. Anopheles darlingi was the most common mosquito in the region. We discuss Culicidae systematics, fauna distribution, and aspects of malaria in altered habitats of the western Amazon. PMID:23152319

Dental maturational sequence and dental tissue proportions in the early Upper Paleolithic child from Abrigo do Lagar Velho, Portugal  

PubMed Central

Neandertals differ from recent and terminal Pleistocene human populations in their patterns of dental development, endostructural (internal structure) organization, and relative tissue proportions. Although significant changes in craniofacial and postcranial morphology have been found between the Middle Paleolithic and earlier Upper Paleolithic modern humans of western Eurasia and the terminal Pleistocene and Holocene inhabitants of the same region, most studies of dental maturation and structural morphology have compared Neandertals only to later Holocene humans. To assess whether earlier modern humans contrasted with later modern populations and possibly approached the Neandertal pattern, we used high-resolution microtomography to analyze the remarkably complete mixed dentition of the early Upper Paleolithic (Gravettian) child from Abrigo do Lagar Velho, Portugal, and compared it to a Neandertal sample, the late Upper Paleolithic (Magdalenian) child of La Madeleine, and a worldwide extant human sample. Some aspects of the dental maturational pattern and tooth endostructural organization of Lagar Velho 1 are absent from extant populations and the Magdalenian specimen and are currently documented only among Neandertals. Therefore, a simple Neandertal versus modern human dichotomy is inadequate to accommodate the morphostructural and developmental variation represented by Middle Paleolithic and earlier Upper Paleolithic populations. These data reinforce the complex nature of Neandertal-modern human similarities and differences, and document ongoing human evolution after the global establishment of modern human morphology.

The Afeio augen-gneiss Suite and the record of the Cariris Velhos Orogeny (1000-960 Ma) within the Riacho do Pontal fold belt, NE Brazil  

NASA Astrophysics Data System (ADS)

Early Tonian (1000-920 Ma) rocks occur within the Transversal Zone of the Borborema Province in Northeast Brazil comprising the 700 km-long sigmoidal Cariris Velhos belt. The Afeio augen-gneiss Suite crops out in the internal zone of the Riacho do Pontal fold belt, about 100 km southwestward of the closest Cariris Velhos occurrence within the Transversal Zone, and has been proposed to represent a continuation of this belt within the Southern subprovince of the Borborema Province. Several plutons included within this unit intrude or are thrust upon metavolcanosedimentary sequences of three different units (Santa Filomena, Paulistana and Morro Branco complexes). The Afeio Suite is composed mostly of calc-alkaline, high-K, peraluminous, high-silica ferroan and magnesian granites. Chondrite-normalized REE patterns are moderate to highly fractionated, with a pronounced negative Eu anomaly. Incompatible element spidergrams show a negative Nb-Ta anomaly, akin to convergence setting (Cordilleran-type) granites. U-Pb zircon data constrain the age of crystallization between 1000 and 960 Ma, thus confirming chrono-correlation with the Cariris Velhos belt. Values of ?Nd(t) between -1.0 and +3.1 and TDM of 1.2-1.5 Ga, similar to other Cariris Velhos occurrences, suggest variable mixing of Tonian juvenile sources with older crustal sources, the latter involving Archean/Paleoproterozoic basement. Although there are currently no reliable geochronological data for the supracrustal sequences of the internal zone, cross-cutting relationships indicate that the Santa Filomena and Morro Branco complexes are older or of similar age to the Afeio Suite, and thus could be related to the Cariris Velhos Orogeny. Based on petrographic, lithogeochemical, geochronological and isotope data, and according to previous models proposed for the Cariris Velhos belt, we interpret the Afeio Suite as the southwestern edge of a continental margin magmatic arc accreted to this portion of West Gondwana during the Early Tonian. Late-Brasiliano dextral displacement through the western branch of the Pernambuco shear zone separated these Cariris Velhos occurrences from its equivalents within the Transversal Zone of the Borborema Province (Recanto-type augen-gneiss of the Alto Paje Terrane).

[Seroprevalence of Helicobacter pylori infection among children of different socioeconomic levels in Porto Velho, State of Rondnia].  

PubMed

This study investigated the seroprevalence of Helicobacter pylori infection in 200 children in the city of Porto Velho, State of Rondnia, divided in two groups of 100 children. The prevalence of seropositivity varied considerably according to socioeconomic level, such that 51% of the lower-level children and 24% of the middle-class children were positive. The characteristics of the child population relating to sex, ethnicity and diet did not represent risk factors for acquiring the infection. However, most of the infected children were in the age group of five years or older, independent of socioeconomic level. The phenotypic distribution of ABO blood groups among the infected and uninfected individuals showed that the seroreactivity to Helicobacter pylori was greater among the children with the O blood type, thus suggesting that these children have greater genetic susceptibility to infection by Helicobacter pylori.

Risk factors and prevalence of newborn hearing loss in a private health care system of Porto Velho, Northern Brazil  

PubMed Central

OBJECTIVE: To determine the prevalence of hearing loss and to analyze the results of newborn hearing screening and audiological diagnosis in private health care systems. METHODS Cross-sectional and retrospective study in a database of newborn hearing screening performed by a private clinic in neonates born in private hospitals of Porto Velho, Rondnia, Northern Brazil. The screening results, the risk for hearing loss, the risk indicators for hearing loss and the diagnosis were descriptively analyzed. Newborns cared in rooming in with their mothers were compared to those admitted to the Intensive Care Unit regarding risk factors for hearing loss. RESULTS: Among 1,146 (100%) enrolled newborns, 1,064 (92.8%) passed and 82 (7.2%) failed the hearing screening. Among all screened neonates, 1,063 (92.8%) were cared in rooming and 83 (7.2%) needed intensive care; 986 (86.0%) were considered at low risk and 160 (14.0%) at high risk for hearing problems. Of the 160 patients identified as having high risk for hearing loss, 83 (37.7%) were admitted to an hospitalized in the Intensive Care Unit, 76 (34.5%) used ototoxic drugs and 38 (17.2%) had a family history of hearing loss in childhood. Hearing loss was diagnosed in two patients (0.2% of the screened sample). CONCLUSIONS: The prevalence of hearing loss in newborns from private hospitals was two cases per 1,000 evaluated patients. The use of ototoxic drugs, admission to Intensive Care Unit and family history of hearing loss were the most common risk factors for hearing loss in the studied population. PMID:24142311

[Indicator of socio-environmental vulnerability in the Western Amazon. The case of the city of Porto Velho, State of Rondnia, Brazil].  

PubMed

The accelerated process of urbanization in the State of Amaznia associated with changes in the patterns of exploitation of natural resources have resulted in several types of environmental impacts, such as urban air pollution produced by forest fires which alters the relationship between urban and rural areas and establishes new vulnerabilities. The scope of this study is to analyze the socio-environmental vulnerability in relation to forest fires and health effects in the urban area of Porto Velho, located in the Brazilian Amazon region. Data was analyzed using a synthetic indicator combining income and education aspects, housing infrastructure, environmental exposure and health effects. The findings indicate that 51% of the resident population, i.e. around 157,000 inhabitants, is exposed to conditions of high and extreme environmental vulnerability. Analysis of the dimensions used to construct the synthetic indicator reveals an intense heterogeneity in terms of socio-environmental vulnerability in the urban area of the city of Porto Velho. These results highlight the need for integrated actions from different government departments in order to enhance health promotion, ecological sustainability and also reduce social inequalities in health.

The geology of the Morro Velho gold deposit in the Archean Rio das Velhas greenstone belt, Quadrila??tero Ferri??fero, Brazil  

USGS Publications Warehouse

The Morro Velho gold deposit, Quadrila??tero Ferri??fero region, Minas Gerais, Brazil, is hosted by rocks at the base of the Archean Rio das Velhas greenstone belt. The deposit occurs within a thick carbonaceous phyllite package, containing intercalations of felsic and intermediate volcaniclastic rocks and dolomites. Considering the temporal and spatial association of the deposit with the Rio das Velhas orogeny, and location in close proximity to a major NNW-trending fault zone, it can be classified as an orogenic gold deposit. Hydrothermal activity was characterized by intense enrichment in alteration zones of carbonates, sulfides, chlorite, white mica??biotite, albite and quartz, as described in other Archean lode-type gold ores. Two types of ore occur in the deposit: dark gray quartz veins and sulfide-rich gold orebodies. The sulfide-rich orebodies range from disseminated concentrations of sulfide minerals to massive sulfide bodies. The sulfide assemblage comprises (by volume), on average, 74% pyrrhotite, 17% arsenopyrite, 8% pyrite and 1% chalcopyrite. The orebodies have a long axis parallel to the local stretching lineation, with continuity down the plunge of fold axis for at least 4.8??km. The group of rocks hosting the Morro Velho gold mineralization is locally referred to as lapa seca. These were isoclinally folded and metamorphosed prior to gold mineralization. The lapa seca and the orebodies it hosts are distributed in five main tight folds related to F1 (the best examples are the X, Main and South orebodies, in level 25), which are disrupted by NE- to E-striking shear zones. Textural features indicate that the sulfide mineralization postdated regional peak metamorphism, and that the massive sulfide ore has subsequently been neither metamorphosed nor deformed. Lead isotope ratios indicate a model age of 2.82 ?? 0.05??Ga for both sulfide and gold mineralization. The lapa seca are interpreted as the results of a pre-gold alteration process and may be divided into carbonatic, micaceous and quartzose types. The carbonatic lapa seca is subdivided into gray and brown subtypes. Non-mineralized, gray carbonatic lapa seca forms the hanging wall to the orebodies, and is interpreted as the product of extreme CO2 metasomatism during hydrothermal alteration. This dolomitic lapa seca ranges in composition from relatively pure limestone and dolomite to silty limestone and dolomite. The brown carbonatic and micaceous lapa secas are the host rocks to gold. These units are interpreted to correspond to the sheared and hydrothermal products of metamorphosed volcaniclastic and/or volcanic rocks of varying composition from dacitic to andesitic, forming various types of schists and phyllites. The high-grade, massive sulfide orebodies occur at the base of the gray carbonatic lapa seca. Both disseminated mineralization and quartz veins are hosted by micaceous lapa seca. The data are consistent with a model of epigenetic mineralization for the lapa seca, from a hydrothermal fluid derived in part from the Archean basement or older crust material. ?? 2007 Elsevier B.V.

On the metallicities of UM 133, UM 283 and UM 382  

E-print Network

The study of group properties of the extremely metal-deficient gas-rich local dwarfs is very promising for the understanding the galaxy formation process at high redshifts. About 20 such objects have been picked up from the literature in the recent review by Kunth & Ostlin(2000). However part of these galaxies got low metallicity as a result of earlier observations, and can have rather large uncertainties in their cited element abundances. Before to perform the detailed studies of such galaxies as of some extreme group, it is useful to revise their metallicities. We present the results of the SAO 6m telescope spectrophotometry of two Blue Compact Galaxies (BCG) reported from earlier studies as very metal-poor objects. Well measured [O III] line 4363 A allows to deduce the temperature in HII regions and get reliable abundances of chemical elements. For UM 133 we derive 12+log(O/H) = 7.63+/-0.02, coincident with the published value. UM 382, according to our data, is significantly more metal-rich: its 12+log(O/H) = 7.82+/-0.03 in comparison to the published value 7.45. The third galaxy, UM 283 seems have got its very low 12+log(O/H) = 7.59 due to a misprint. We used its published emission line intensities and derived instead the value of 7.95. Thus the latter two galaxies should NOT be considered as the extremely metal-poor BCGs.

Upconversion single photon detection near 2 um  

E-print Network

We have demonstrated upconversion detection at the single photon level in the 2 um spectral window using a pump wavelength near 1550nm, a periodically poled lithium niobate (PPLN) waveguide, and a volume Bragg grating (VBG) to reduce noise. We achieve a system photon detection efficiency of 10%, with a noise count rate of 24,500 counts per second, competitive with other 2 um single photon detection technologies. This detector has potential applications in environmental gas monitoring, life science, and classical and quantum communication.

Estas ltimas contribuies so devi-das emisso de corpo negro temperatura ambiente e aumentam exponencialmente para comprimentos de onda maiores que 2 micra (banda K, no infravermelho prximo). Embora a resultante pode ser quantificada e subtrada dos sinais relevantes, sua varincia se adiciona varincia do sinal, e pode ser facilmente a contribuio domi-nante para a incerteza final das medidas, tornando ineficiente o processo de extrao de informao e degradando a sensibilidade da cmara. A maneira clssica de resolver esse problema em sistemas pticos que operam no infravermelho, onde os efeitos da emisso trmica do ambiente so importantes, restringir o ngulo slido subtendido pelos pixels individuais exclusivamente aos raios provenientes do sistema ptico. Para tanto, projeta-se uma imagem real, bastante reduzida, da pupila de entrada do sistema ptico num anteparo que transmita para o sistema de imageamento s o que interessa, bloqueando as contribuies das bordas externas pupila de entrada, obstruo central do telescpio e sistema de suporte.

10 um wavefront spatial filtering: first results with chalcogenide fibers  

E-print Network

Wavefront cleaning by single-mode fibers has proved to be efficient in optical-infrared interferometry to improve calibration quality. For instance, the FLUOR instrument has demonstrated the capability of fluoride glass single-mode fibers in this respect in the K and L bands. New interferometric instruments developped for the mid-infrared require the same capability for the 8-12 um range. We have initiated a program to develop single-mode fibers in the prospect of the VLTI mid-infrared instrument MIDI and of the ESA/DARWIN and NASA/TPF missions that require excellent wavefront quality. In order to characterize the performances of chalcogenide fibers we are developping, we have set up an experiment to measure the far-field pattern radiated at 10 um. In this paper, we report the first and promising results obtained with this new component.

Resultados do desenvolvimento de um propulsor plasma no Brasil

Uma das partes mais importantes de um satlite o controle de atitude do mesmo. E se tratando de um satlite cientfico, a ateno para este sistema deve ser redobrada. Uma possibilidade atraente para executar esta tarefa a propulso eltrica. Aqui, mostraremos resultados obtidos pelo propulsor plasma PHALL-01, desenvolvido na Universidade de Braslia entre 2000 e 2003. Este derivado do propulsor russo SPT-100 (Stationary Plasma Thruster), mas com o emprego inovador de um arranjo de ims permanentes como fonte do campo magntico, este ltimo o agente da acelerao do plasma. Esta alterao foi motivada pelo objetivo de que o mesmo operasse com o mnimo de potncia eltrica. A partir da formulao terica do mecanismo de acelerao, tendo como base as equaes da magnetohidrodinmica, pode-se obter vnculos sob os quais o propulsor pudesse ser construdo. O mais forte destes o que dita a topologia do campo magntico. Sendo assim, foram realizadas simulaes computacionais, que definiram a geometria do propulsor.

We investigate the far-infrared SED of the Galaxy and the Magellanic Clouds by using the COBE (COsmic Background Explorer) / DIRBE (Diffuse InfraRed Background Experiment) ZSMA (Zodi - Subtracted Mission Average) maps at wavelengths of 60 um, 100 um and 140 um. We analyze three regions: the Galactic plane region with the Galactic latitude |b|um and 60 - 100 um intensity ratios in all the three galaxies. Although this color correlation cannot be explained by any existing model, it fits very well the far-infrared color of nearby star forming galaxies.

STAR CLUSTER COMPLEXES AND THE HOST GALAXY IN THREE H II GALAXIES: Mrk 36, UM 408, AND UM 461  

SciTech Connect

We present a stellar population study of three H II galaxies (Mrk 36, UM 408, and UM 461) based on the analysis of new ground-based high-resolution near-infrared J, H, and K{sub p} broadband and Br{gamma} narrowband images obtained with Gemini/NIRI. We identify and determine the relative ages and masses of the elementary star clusters and/or star cluster complexes of the starburst regions in each of these galaxies by comparing the colors with evolutionary synthesis models that include the contribution of stellar continuum, nebular continuum, and emission lines. We found that the current star cluster formation efficiency in our sample of low-luminosity H II galaxies is {approx}10%. Therefore, most of the recent star formation is not in massive clusters. Our findings seem to indicate that the star formation mode in our sample of galaxies is clumpy, and that these complexes are formed by a few massive star clusters with masses {approx}>10{sup 4} M{sub Sun }. The age distribution of these star cluster complexes shows that the current burst started recently and likely simultaneously over short timescales in their host galaxies, triggered by some internal mechanism. Finally, the fraction of the total cluster mass with respect to the low surface brightness (or host galaxy) mass, considering our complete range in ages, is less than 1%.

The 15-20 um emission in the reflection nebula NGC2023  

E-print Network

We present 15-20 um spectral maps towards the reflection nebula NGC2023 obtained with the Infrared Spectrograph in short-wavelength, high-resolution mode on board the Spitzer Space Telescope. These spectra reveal emission from PAHs, C60, and H2 superposed on a dust continuum. These emission components exhibit distinct spatial distributions: with increasing distance from the illuminating star, we observe the PAH emission followed by the dust continuum emission and the H2 emission. The C60 emission is located closest to the illuminating star in the south while in the north, it seems to be associated with the H/H2 transition. Emission from PAHs and PAH-related species produce features at 15.8, 16.4, 17.4, and 17.8 um and the 15-18 um plateau. These different PAH features show distinct spatial distributions. The 15.8 um band and 15-18 um plateau correlate with the 11.2 um PAH band and with each other, and are attributed to large, neutral PAHs. Conversely, the 16.4 um feature correlates with the 12.7 um PAH band, ...

New near-infrared observations and lens-model constraints for UM673  

NASA Astrophysics Data System (ADS)

Aims: We performed a detailed photometric analysis of the lensed system UM673 (Q0142-100) and an analysis of the tentative lens models. Methods: High-resolution adaptive optics images of UM673 taken with the Subaru telescope in the H band were examined. We also analysed the J, H and K-band observational data of UM673 obtained with the 1.3 m telescope at the CTIO observatory. Results: We present photometry of quasar components A and B of UM673, the lens, and the nearby bright galaxy using H-band observational data obtained with the Subaru telescope. Based on the CTIO observations of UM673, we also present J- and H-band photometry and estimates of the J, H and K-band flux ratios between the two UM673 components in recent epochs. The near-infrared fluxes of the A and B components of UM673 and their published optical fluxes are analysed to measure extinction properties of the lensing galaxy. We estimate the extinction-corrected flux ratio between components A and B to be about 2.14 mag. We discuss lens models for the UM673 system constrained with the positions of the UM673 components, their flux ratio, and the previously measured time delay. Based in part on data collected at Subaru Telescope, which is operated by the National Astronomical Observatory of Japan.The final reduced Subaru images presented in Figs. 1 and 2 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/566/A36

We evaluate the performances of a 100 um-thick silicon strip detector (SSD) with a 300 MeV proton beam and a 90Sr beta-ray source. Signals from the SSD have been read out using a VLSI chip. Common-mode noise, signal separation efficiency and energy resolution are compared with those for the SSD's with a thickness of 300 um and 500 um. Energy resolution for minimum ionizing particles (MIP's) is improved by fitting the non-constant component in a common-mode noise with a linear function.

2 um Narrow-Band Imaging of the Sagittarius D H II region  

E-print Network

We present 2 um narrow-band images of the core H II region in the Galactic star forming region Sagittarius D. The emission-line images are centered on 2.17 um (Brgamma) and 2.06 um (He I). The H II region appears at the edge of a well defined dark cloud, and the morphology suggests a blister geometry as pointed out in earlier radio continuum work. There is a deficit of stars in general in front of the associated dark cloud indicating the H II region is located in-between the Galactic center and the sun. The lesser spatial extent of the He I line emission relative to Brgamma places the effective temperature of the ionizing radiation field below 40,000 K. The He I 2.06 um to Brgamma ratio and Brgamma / far infrared dust emission put Teff at about 36,500 K to 40,000 K as derived from ionization models.

The 1 um discontinuity in the Extragalactic Background Light spectrum: an artefact of foreground subtraction  

E-print Network

Several recent papers claim the detection of a near infrared Extragalactic Background Light (EBL) intensity at 1.25 - 4 um that exceeds the integrated light of galaxies by factors of >3. When combined with a claimed optical detection of the EBL at 0.80 um the EBL excess emission spectrum has a discontinuity at ~1 um. This discontinuity has given rise to an interpretation in terms of ultraviolet radiation emanating from the first generation of massive stars at redshifts of 7 - 20 (so called Population III stars). The interpretation of the NIR excess emission as being of extragalactic origin depends crucially on the model used in the subtraction of the Zodiacal Light, the dominant foreground contaminant. We estimate the Zodiacal Light at 0.80 um using on the one hand the measurement by Bernstein et al.,2002, ApJ, 571,85), with corrections for some omitted effects of atmospheric scattering and calibration, and on the other hand the model of Kelsall et al.,1998, ApJ, 508,44). There is in neither case any evidence for a step in the EBL at ~1 um. We emphasize that in order to avoid systematic effects it is essential to use the same Zodiacal Light model (Kelsall et al. 1998) for both the NIR (1.25 - 4 um) and optical (0.80 um) data. We emphasize, however, that our analysis does not allow a statement on the overall level of the NIR EBL. The contribution of the Diffuse Galactic Light to the ``EBL excess'' emission is estimated. It is found to be significant at 3 - 4 um and should be carefully evaluated in future measurements which aim at detecting an EBL signal at the level of ~10 nW m^-2 sr^-1, i.e. at the level of the integrated light of (known) galaxies.

Spitzer Mid-Infrared Spectroscopy of 70um-Selected Distant Luminous Infrared Galaxies  

E-print Network

We present mid-infrared spectroscopy obtained with the Spitzer Space Telescope of a sample of 11 optically faint, infrared luminous galaxies selected from a Spitzer MIPS 70um imaging survey of the NDWFS Bootes field. These are the first Spitzer IRS spectra presented of distant 70um-selected sources. All the galaxies lie at redshifts 0.3um silicate absorption features and no significant PAH emission features (6.2um equivalent widths < 0.03um). The large infrared luminosities and low f70/f24 flux density ratios suggests that these sources have AGN as the dominant origin of their large mid-infrared luminosities, although deeply embedded but luminous starbursts cannot be ruled out. If the absorbed sources are AGN-dominated, a significant fraction of all far-infrared bright, optically faint sources may be dominated by AGN.

UM-PRS: An implementation of the procedural reasoning system for multirobot applications  

NASA Technical Reports Server (NTRS)

The Procedural Reasoning System (PRS) is used in applications where predetermined situations might arise. The UM-PRS provides a reasoning system that represents robotic applications even in unpredictable domains, such as the robotic reconnaissance task domain outlined here. UM-PRS incorporates a changing context, rather than relying solely on a prearranged plan. The UM-PRS here provides representation important in the reasoning and interface between a mission plan and the executable map of an outdoor vehicle that changes its behavior based on what it comes in contact with in its environment. PRS is thus used in the dynamic control of such a vehicle, providing the basis for coordinating the joint task of multiple robotic vehicles by the their individual observations and representation.

8--13 um spectroscopy of YSOs: Evolution of the silicate feature  

E-print Network

In order to investigate possible connections between dust processing and disk properties, 8--13 um spectra of 34 young stars, with a range of circumstellar environments and spectral types A to M, were obtained using the Long Wavelength Spectrometer at the W. M. Keck Observatory. The broad 9.7 um amorphous silicate feature which dominates this wavelength regime evolves from absorption in young, embedded sources, to emission in optically revealed stars, and to complete absence in older debris disk systems for both low- and intermediate-mass stars. The peak wavelength and FWHM are centered about 9.7 and ~2.3 um, corresponding to amorphous olivine, with a larger spread in FWHM for embedded sources and in peak wavelength for disks. In a few of our objects that have been previously identified as class I low-mass YSOs, the observed silicate feature is complex, with absorption near 9.5 um and emission peaking around 10 um. Although most of the emission spectra show broad classical features attributed to amorphous silicates, variations in the shape/strength may be linked to dust processing, including grain growth and/or silicate crystallization. We study quantitatively the evidence for evolutionary trends in the 8--13 um spectra through a variety of spectral shape diagnostics. Based on the lack of correlation between these diagnostics and broad-band infrared luminosity characteristics for silicate emission sources, we conclude that although spectral signatures of dust processing are present, they can not be connected clearly to disk evolutionary stage (for optically thick disks) or optical depth (for optically thin disks). The diagnostics of silicate absorption features (other than the central wavelength of the feature), however, are tightly correlated with optical depth.

MetUM-GOML: a near-globally coupled atmosphere-ocean-mixed-layer model  

NASA Astrophysics Data System (ADS)

Well-resolved air-sea interactions are simulated in a new Ocean Mixed Layer coupled configuration of the Met Office Unified Model (MetUM-GOML), comprising the MetUM coupled to the Multi-Column K Profile Parametrization ocean (MC-KPP). This is the first globally coupled system which provides a vertically resolved, high near-surface resolution ocean at comparable computational cost to running in atmosphere-only mode. As well as being computationally inexpensive, this modelling framework is adaptable - the independent MC-KPP columns can be applied selectively in space and time - and controllable - by using temperature and salinity corrections the model can be constrained to any ocean state. The framework provides a powerful research tool for process-based studies of the impact of air-sea interactions in the global climate system. MetUM simulations have been performed which separate the impact of introducing interannual variability in sea surface temperatures (SSTs) from the impact of having atmosphere-ocean feedbacks. The representation of key aspects of tropical and extra-tropical variability are used to assess the performance of these simulations. Coupling the MetUM to MC-KPP is shown, for example, to reduce tropical precipitation biases, improve the propagation of, and spectral power associated with, the Madden-Julian Oscillation and produce closer-to-observed patterns of springtime blocking activity over the Euro-Atlantic region.

Detection of the 205 um [NII] Line from the Carina Nebula  

E-print Network

We report the first detection of the 205 um 3P1 - 3P0 [NII] line from a ground-based observatory using a direct detection spectrometer. The line was detected from the Carina star formation region using the South Pole Imaging Fabry-Perot Interferometer (SPIFI) on the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) at South Pole. The [NII] 205 um line strength indicates a low-density (n ~ 32 cm^-3 ionized medium, similar to the low-density ionized halo reported previously in its [OIII] 52 and 88 um line emission. When compared with the ISO [CII] observations of this region, we find that ~27% of the [CII] line emission arises from this low-density ionized gas, but the large majority ~ 73% of the observed [CII] line emission arises from the neutral interstellar medium. This result supports and underpins prior conclusions that most of the observed [CII] 158 um line emission from Galactic and extragalactic sources arises from the warm, dense photodissociated surfaces of molecular clouds. The detection of the [NII] line demonstrates the utility of Antarctic sites for THz spectroscopy.

The merging dwarf galaxy UM 448: chemodynamics of the ionized gas from VLT integral field spectroscopy  

NASA Astrophysics Data System (ADS)

Using Very Large Telescope/Fibre Large Array Multi Element Spectrograph optical integral field unit observations, we present a detailed study of UM 448, a nearby blue compact galaxy (BCG) previously reported to have an anomalously high N/O abundance ratio. New Technology Telescope/Superb-Seeing Imager images reveal a morphology suggestive of a merger of two systems of contrasting colour, whilst our H? emission maps resolve UM 448 into three separate regions that do not coincide with the stellar continuum peaks. UM 448 exhibits complex emission line profiles, with most lines consisting of a narrow [full width at half-maximum (FWHM) ? 100 km s-1], central component, an underlying broad component (FWHM 150-300 km s-1) and a third, narrow blueshifted component. Radial velocity maps of all three components show signs of solid body rotation across UM 448, with a projected rotation axis that correlates with the continuum morphology of the galaxy. A spatially resolved, chemodynamical analysis, based on the [O iii] ??4363, 4959, [N ii] ?6584, [S ii] ??6716, 6731 and [Ne iii] ?3868 line maps, is presented. Whilst the eastern tail of UM 448 has electron temperatures (Te) that are typical of BCGs, we find a region within the main body of the galaxy where the narrow and broad [O iii] ?4363 line components trace temperatures differing by 5000 K and oxygen abundances differing by 0.4 dex. We measure spatially resolved and integrated ionic and elemental abundances for O, N, S and Ne throughout UM 448, and find that they do not agree, possibly due the flux weighting of Te from the integrated spectrum. This has significant implications for abundances derived from long-slit and integrated spectra of star-forming galaxies in the nearby and distant universe. A region of enhanced N/O ratio is indeed found, extended over a 0.6 kpc2 region within the main body of the galaxy. Contrary to previous studies, however, we do not find evidence for a large Wolf-Rayet (WR) population, and conclude that WR stars alone cannot be responsible for producing the observed N/O excess. Instead, the location and disturbed morphology of the N-enriched region suggest that interaction-induced inflow of metal-poor gas may be responsible.

Variability of the broad absorption lines in the QSO UM 232  

NASA Technical Reports Server (NTRS)

Low-resolution spectra of UM 232 taken in 1978, 1979, and 1988 at Lick Observatory are presented. Large changes in the Si IV lambda 1397, CIV lambda 1549, and Al III lambda 1857 broad absorption lines are apparent. The decrease in column density in all three ions and an observed brightening of the QSO suggests that these changes are due to an increase in the ionization level driven by an increase in the central source luminosity. This mechanism has been proposed by Smith and Penston to explain small changes in the absorption spectrum of the QSO 1246-057. The spectra of UM 232 show that the fractional decrease in optical depth is smaller at higher outflow velocies. The structure of the broad absorption-line region (BALR) is investigted by estimating an ionization parameter for each ion species as a function of velocity.

ISOPHOT CIRB project: FIR source counts at 90, 150 and 180 um  

E-print Network

Far-infrared maps obtained with ISOPHOT have been searched for point-like sources. The majority of the 55 sources is believed to be extragalactic and in most cases no previously known sources can be associated with them. Based on the far-infrared spectral energy distributions it is likely that dust-enshrouded, distant galaxies form a significant fraction of the sources. We estimate the number densities of extragalactic sources at 90, 150 and 180 um wavelengths and at flux density levels down to 100 mJy. The counts are compared with models of galaxy evolution. The counts exceed the predictions of current models, even those with strong evolution, and no-evolution models are rejected at a high confidence level. Comparison with recent results from COBE mission indicates that at 90 um the detected sources correspond to over 20% of the extragalactic background light. At longer wavelengths the corresponding fraction is 10%.

We carried out H-band observations of UM673 with the Subaru Infra-Red Camera and Spectrograph (IRCS) using an adaptive optics system with 188 control elements (AO188). The images were reduced following the procedure described in "Subaru Data Reduction CookBook: Imaging Observation with IRCS" by Y. Minowa (see also Minowa et al. 2005ApJ...629...29M). The final Subaru H-band stack image of UM673 was created by coadding 22 reduced single exposure images. We also created the exposure time map of the stack image. The 17x10arcsec subframe of the stack image and the corresponding exposure map displayed in Figures 1 and 2 of the paper are available as fits files. (2 data files).

A deep 6.7um survey in the SSA13 field with ISO  

E-print Network

We present results of a deep mid-infrared survey in the SSA13 field with the Infrared Space Observatory (ISO). In order to probe the near-infrared light at high redshifts, we surveyed the field with the broad band LW2 (5-8.5um) filter of the mid-infrared camera ISOCAM. Adopting a highly redundant imaging strategy for the 23 hour observation and carefully treating gradual changes in the detector responsivity caused by a very high rate of cosmic ray impacts, we succeeded in reaching an 80% completeness limit of 16uJy in the central 7 arcmin2 region. Utilizing the signal-to-noise ratio map, we detected 65 sources down to 6uJy in the 16 arcmin2 field. Integral galaxy number counts at 6.7um are then derived, reaching 1.3e4/deg2 at the faint limit with a slope of -1.6 between 13uJy and 130uJy. Integrating individual sources in this flux range, the resolved fraction of the extragalactic background light at 6.7um is estimated to be 0.56nW/m2/sr. These results, which reach a flux limit three times fainter than those in the Hubble Deep Fields, are in fairly good agreement with a model prediction by Franceschini et al. (1997). Finally, we discuss the relation of distant massive E/S0 galaxies to the faint 6.7um galaxy population.

Photometric Variability of the Gravitational Lens 0142-100 (UM 673)  

E-print Network

We present the results of a photometric CCD monitoring of the gravitational lens system UM 673, that took place from 1995 to 2000. In total, the doubly-imaged quasar was observed in the R-band during 29 photometric nights, using optical telescopes with dimensions in the range 0.6 m to 1.3 m. We detected a significant variability in the total light of the UM 673 system, that is, in the light of the two QSO images plus the lensing galaxy. With respect to the magnitude of the gravitational lens system at its discovery, in 1986, UM 673 was 0.3 magnitude brighter. Furthermore, our December 1996 measurements show that between November 1995 and October 1997 the system became even brighter, reaching a magnitude difference of 0.5 magnitude with respect to its discovery value. We also present R magnitudes and V-R colours of seven field stars situated in the vicinity of the lens, based on a 3.5-month monitoring during the year 2000.

The UM-Dearborn Observatory: Variable-object Research from an Urban Site  

NASA Astrophysics Data System (ADS)

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

AKARI IRC 2.5-5 um Spectroscopy of Infrared Galaxies over a Wide Luminosity Range  

E-print Network

We present the result of a systematic infrared 2.5-5 um spectroscopic study of 22 nearby infrared galaxies over a wide infrared luminosity range (10 heated by an active galactic nucleus (AGN). Applying our AGN diagnostics to the AKARI spectra, we discover 14 buried AGNs. The large fraction of buried AGNs suggests that AGN activity behind the dust is almost ubiquitous in ultra-/luminous infrared galaxies (U/LIRGs). We also find that both the fraction and energy contribution of buried AGNs increase with infrared luminosity from 10 energy contribution from AGNs in the total infrared luminosity is only ~7% in LIRGs and ~20% in ULIRGs, sug...

University AlbUM: A Digital Collection of University of Maryland Images  

NSDL National Science Digital Library

The Old Line State has long been home to a number of fine institutions of higher education, and the flagship public university is the University of Maryland in College Park. Their library system has been involved in creating a number of digital collections, and the impetus for this particular offering was the University's 150th anniversary celebration. Drawing on their broad archive of historical photographs, they have created the University AlbUM website to intrigue and entice those who might wish to learn a bit more about the University's past. Visitors to the site can browse the photographs via a set of themes, including "Sports", "Agriculture", "Campus + Buildings", "Events", and "People". Those persons with a temporal bent may wish to browse the photographs by decade to find documents such as minutes from the campus literary society and illustrations from various campus publications.

Noise Performance Comparison of 1.5 um Correlated Photon Pair Generation in Different Fibers  

E-print Network

In this paper, the noise performances of 1.5 um correlated photon pair generations based on spontaneous four wave-mixing in three types of fibers, i.e., dispersion shifted fiber, highly nonlinear fiber, and highly nonlinear microstructure fiber are investigated experimentally. Result of the comparison shows that highly nonlinear microstructure fiber has the lowest Raman noise photon generation rate among the three types of fibers while correlated photon pair generation rate is the same. Theoretical analysis shows that the noise performance is determined by the nonlinear index and Raman response of the material in fiber core. The Raman response raises with increasing doping level, however, the nonlinear index is almost unchanged with it. As a result, highly nonlinear microstructure fiber with pure silica core has the best noise performance and has great potential in practical sources of correlated photon pairs and heralded single photons.

Properties of 1.5 um synchronous heralded single photon sources based on optical fiber  

E-print Network

A 1.5 um synchronous heralded single photon source (HSPS) is experimentally demonstrated based on dispersion shifted fiber and commercial fiber components in the paper. Experimental results show that both the preparation efficiency and the conditional second order correlation function g2(0) increase with the pump light level. Between the two important parameters, tradeoff should be taken in order to obtain a high quality fiber-based synchronous HSPS. A synchronous HSPS with a prepare efficiency of >60% and g2(0)<0.06 is achieved, the multi-photon probability of which is reduced by a factor of more than 16 compared with the Poissonian light sources. The experimental results show a great potential of the fiber-based synchronous HSPS for quantum information applications.

Photometric monitoring (1987 to 1994) of the gravitational lens candidate UM 425  

E-print Network

We present the results of a 7 year long photometric monitoring of two components (A and B) of UM 425, thought to be images, separated by 6.5", of the same z = 1.47 quasar. These components have been imaged through an R filter in order to obtain their light curves. The photometry was obtained by simultaneously fitting a stellar two-dimensional profile on each component. The brightest image (component A, m(R) = 15.7) shows a slow and smooth increase in brightness of 0.2 magnitude in seven years, while the faintest one (component B, m(R) = 20.1) displays an outburst of 0.4 magnitude which lasts approximately two years. The variation of component B may be interpreted in two ways, assuming UM 425 is gravitationally lensed. If it is due to an intrinsic variation of the quasar, we derive a lower limit of 3 years on the time delay from the fact that it is not observed in component A. On the other hand, if it is a microlensing ``High Amplification Event'', we estimate the size of the source to be ~ 10^{-3} pc, in agreement with standard models of AGNs. These observations are consistent with the gravitational lens interpretation of the object. Furthermore, all the CCD frames obtained under the best seeing conditions have been co-added, in an attempt to detect the deflector. The final R image reveals a rich field of faint galaxies in the magnitude range m(R) 22-24. No obvious deflector, nor any system of arcs or arclets is detected, down to a limiting magnitude of m(R) 24.

Comparative genomic analysis of Mycobacterium iranicum UM_TJL against representative mycobacterial species suggests its environmental origin.  

PubMed

Mycobacterium iranicum is a newly reported mycobacterial species. We present the first comparative study of M. iranicum UM_TJL and other mycobacteria. We found M. iranicum to have a close genetic association with environmental mycobacteria infrequently associated with human infections. Nonetheless, UM_TJL is also equipped with many virulence genes (some of which appear to be the consequence of transduction-related gene transfer) that have been identified in established human pathogens. Taken all together, our data suggest that M. iranicum is an environmental bacterium adapted for pathogenicity in the human host. This comparative study provides important clues and forms the basis for future functional studies on this mycobacterium. PMID:25417557

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.

UM 625 Revisited: Multiwavelength Study of a Seyfert 1 Galaxy with a Low-mass Black Hole  

NASA Astrophysics Data System (ADS)

UM 625, previously identified as a narrow-line active galactic nucleus (AGN), actually exhibits broad H? and H? lines whose width and luminosity indicate a low black hole (BH) mass of 1.6 106 M ?. We present a detailed multiwavelength study of the nuclear and host galaxy properties of UM 625. Analysis of Chandra and XMM-Newton observations suggests that this system contains a heavily absorbed and intrinsically X-ray weak (?ox = -1.72) nucleus. Although not strong enough to qualify as radio loud, UM 625 does belong to a minority of low-mass AGNs detected in the radio. The broadband spectral energy distribution constrains the bolometric luminosity to L bol ? (0.5-3) 1043 erg s-1 and L bol/L Edd ? 0.02-0.15. A comprehensive analysis of Sloan Digital Sky Survey and Hubble Space Telescope images shows that UM 625 is a nearly face-on S0 galaxy with a prominent, relatively blue pseudobulge (Srsic index n = 1.60) that accounts for ~60% of the total light in the R band. The extended disk is featureless, but the central ~150-400 pc contains a conspicuous semi-ring of bright, blue star-forming knots, whose integrated ultraviolet luminosity suggests a star formation rate of ~0.3 M ? yr-1. The mass of the central BH roughly agrees with the value predicted from its bulge velocity dispersion but is significantly lower than that expected from its bulge luminosity.

Star Formation Rates from [CII] 158 um and Mid Infrared Emission Lines for Starbursts and AGN  

E-print Network

A summary is presented for 130 galaxies observed with the Herschel PACS instrument to measure fluxes for the [CII] 158 um emission line. Sources cover a wide range of active galactic nucleus to starburst classifications, as derived from polycyclic aromatic hydrocarbon (PAH) strength measured with the Spitzer Infrared Spectrograph. Redshifts from [CII] and line to continuum strengths (equivalent width of [CII]) are given for the full sample, which includes 18 new [CII] flux measures. Calibration of L([CII)]) as a star formation rate (SFR) indicator is determined by comparing [CII] luminosities with mid-infrared [NeII] and [NeIII] emission line luminosities; this gives the same result as determining SFR using bolometric luminosities of reradiating dust from starbursts: log SFR = log L([CII)]) - 7.0, for SFR in solar masses per year and L([CII]) in solar luminosities. We conclude that L([CII]) can be used to measure SFR in any source to a precision of ~ 50%, even if total source luminosities are dominated by an ...

First ground-based 200-um observing with THUMPER on JCMT - sky characterisation and planet maps  

E-print Network

We present observations that were carried out with the Two HUndred Micron PhotometER (THUMPER) mounted on the James Clerk Maxwell Telescope (JCMT) in Hawaii, at a wavelength of 200 um (frequency 1.5 THz). The observations utilise a small atmospheric window that opens up at this wavelength under very dry conditions at high-altitude observing sites. The atmosphere was calibrated using the sky-dipping method and a relation was established between the optical depth, tau, at 1.5 THz and that at 225 GHz: tau_1.5THz = (95 +/- 10)*tau_225GHz. Mars and Jupiter were mapped from the ground at this wavelength for the first time, and the system characteristics measured. A noise equivalent flux density (NEFD) of ~65 +/- 10 Jy (1 sigma 1 second) was measured for the THUMPER-JCMT combination, consistent with predictions based upon our laboratory measurements. The main-beam resolution of 14 arcsec was confirmed and an extended error-beam detected at roughly two-thirds of the magnitude of the main beam. Measurements of the Sun allow us to estimate that the fraction of the power in the main beam is ~15%, consistent with predictions based on modelling the dish surface accuracy. It is therefore shown that the sky over Mauna Kea is suitable for astronomy at this wavelength under the best conditions. However, higher or drier sites should have a larger number of useable nights per year.

The response of chemistry and climate to the 11-year solar cycle in UM-UKCA  

NASA Astrophysics Data System (ADS)

It is now generally agreed that the UV variability associated with the 11-year solar cycle leads to changes in ozone and temperature in the upper stratosphere. In addition, a range of observational and modelling studies suggest that such changes are the starting point for a chain of processes (including feedbacks) resulting in circulation changes in many areas of the atmosphere. However, precise details of the interactions between chemistry and meteorology induced by solar variability remain under question. In our study, we use a version of the UM-UKCA chemistry-climate model with consistent spectrally-resolved solar variability. While the solar cycle in heating rates has been applied with the method used in HadGEM2-ES, fine spectrally-resolved solar variability has been uniquely incorporated into the Fast-JX photolysis scheme. We perform two 50-year-long perpetual year solar maximum and solar minimum integrations and complement them with a three member ensemble of a transient 1960-2010 integration in which boundary conditions correspond by and large to the CCMI Ref-C1 scenario. We show how the inferred solar signals vary between the individual experiments. This indicates high natural variability and the resulting contamination of the solar signal with contributions from other processes as well as the existence of possible non-linearities between the solar cycle and other atmospheric forcings. Therefore, we highlight that long data series are needed to ensure correct attribution of the modelled and observed anomalies. In addition, we present results from two perpetual year experiments in which the solar cycle was applied exclusively in either short-wave heating or photolysis. We find large non-linearities in the modelled anomalies as compared to the realistic integration with both modulations included. This highlights the subtle nature of the dynamical response to the solar cycle forcing and indicates the need for interactive chemistry with a detailed photolysis scheme for modelling the solar-climate interactions fully.

Project UM-HAUL: A self-unloading reusable lunar lander  

NASA Technical Reports Server (NTRS)

The establishment of a lunar base is technologically and financially challenging. Given the necessary resources and political support, it can be done. In addition to the geopolitical obstacles, however, there are logistical problems involved in establishing such bases that can only be overcome with the acquisition of a significant transportation and communications network in the Earth-Moon spatial region. Considering the significant number of payloads that will be required in this process, the mass-specific cost of launching these payloads, and the added risk and cost of human presence in space, it is clearly desirable to automate major parts of such an operation. One very costly and time-consuming factor in this picture is the delivery of payloads to the Moon. Foreseeable payloads would include atmospheric modules, inflatable habitat kits, energy and oxygen plant elements, ground vehicles, laboratory modules, crew supplies, etc. The duration of high-risk human presence on the Moon could be greatly reduced if all such payloads were delivered to the prospective base site in advance of crew arrival. In this view, the idea of a 'Self-Unloading Reusable Lunar Lander' (SURLL) arises naturally. The general scenario depicts the lander being brought to low lunar orbit (LLO) from Earth atop a generic Orbital Transfer Vehicle (OTV). From LLO, the lander shuttles payloads down to the lunar surface, where, by means of some resident, detachable unloading device, it deploys the payloads and returns to orbit. The general goal is for the system to perform with maximum payload capability, automation, and reliability, while also minimizing environmental hazards, servicing needs, and mission costs. Our response to this demand is UM-HAUL, or the UnManned Heavy pAyload Unloader and Lander. The complete study includes a system description, along with a preliminary cost analysis and a design status assessment.

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

The C IV lambda 1549 and N V 1240 doublets at z(sub a) = 2.1340 (shifted approximately 1500 km/s from z(sub e) 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 z(sub a) approximately equal z(sub e) 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 10(exp 18)/sq cm in the low-ionization gas to approximately 10(exp 20)/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 z(sub a) approximately equal to z(sub e) 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 N(sub H) greater than or approximately equal to 10(exp 21)/sq cm (for solar abundances).

ON THE COMPACT H II GALAXY UM 408 AS SEEN BY GMOS-IFU: PHYSICAL CONDITIONS  

SciTech Connect

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''x4.''4 equivalent with {approx}750 pc x 1100 pc located in the central part of the galaxy. The starburst in this area is resolved into two giant regions of about 1.''5 and 1'' ({approx}375 and {approx}250 pc) diameter, respectively and separated 1.5-2'' ({approx}500 pc). The extinction distribution concentrate its highest values close but not coincident with the maxima of H{alpha} 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{beta} equivalent widths, suggest that they are coeval events of {approx}5 Myr with stellar masses of {approx}10{sup 4} M {sub sun}. We have also used [O III]/H{beta} and [S II]/H{alpha} 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{alpha} 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 {approx}10 km s{sup -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 {delta}(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{sigma} dispersion (with {sigma} = 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.

Community Structure and Activity of a Highly Dynamic and Nutrient-Limited Hypersaline Microbial Mat in Um Alhool Sabkha, Qatar  

PubMed Central

The Um Alhool area in Qatar is a dynamic evaporative ecosystem that receives seawater from below as it is surrounded by sand dunes. We investigated the chemical composition, the microbial activity and biodiversity of the four main layers (L1L4) in the photosynthetic mats. Chlorophyll a (Chl a) concentration and distribution (measured by HPLC and hyperspectral imaging, respectively), the phycocyanin distribution (scanned with hyperspectral imaging), oxygenic photosynthesis (determined by microsensor), and the abundance of photosynthetic microorganisms (from 16S and 18S rRNA sequencing) decreased with depth in the euphotic layer (L1). Incident irradiance exponentially attenuated in the same zone reaching 1% at 1.7-mm depth. Proteobacteria dominated all layers of the mat (24%42% of the identified bacteria). Anoxygenic photosynthetic bacteria (dominated by Chloroflexus) were most abundant in the third red layer of the mat (L3), evidenced by the spectral signature of Bacteriochlorophyll as well as by sequencing. The deep, black layer (L4) was dominated by sulfate reducing bacteria belonging to the Deltaproteobacteria, which were responsible for high sulfate reduction rates (measured using 35S tracer). Members of Halobacteria were the dominant Archaea in all layers of the mat (92%97%), whereas Nematodes were the main Eukaryotes (up to 87%). Primary productivity rates of Um Alhool mat were similar to those of other hypersaline microbial mats. However, sulfate reduction rates were relatively low, indicating that oxygenic respiration contributes more to organic material degradation than sulfate reduction, because of bioturbation. Although Um Alhool hypersaline mat is a nutrient-limited ecosystem, it is interestingly dynamic and phylogenetically highly diverse. All its components work in a highly efficient and synchronized way to compensate for the lack of nutrient supply provided during regular inundation periods. PMID:24658360

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.

Detection of the 3.3um PAH feature as well as water ice and HAC absorption in z~2 ULIRGs  

E-print Network

We present preliminary results from the highest available signal-to-noise rest-frame 2-8um spectra of z~2 ULIRGs. Our 10 targets are selected for their deep silicate absorption features based on previous shallower IRS spectra. The goal of this follow-up program is: 1) allow for a more accurate analysis of inner/hot dust continuum, 2) detecting the 3.3um and 6.2um PAH features, and 3) detecting molecular absorption features such as due to water ice and hydrocarbons (HACs). We find that the 3.4um HAC absorption feature is observed in four sources, while the 3.05um water ice feature is observed in three of the sources. The HAC detectability is higher and ice detectability lower than expected from local ULIRGs, but consistent with a more AGN-dominated sample such as this one. Where ice is detected, the ice-to-silicate ratio is somewhat lower than many local ULIRGs implying on average thinner ice mantles. One source shows the, to our knowledge, highest redshift reported detection of the 3.3um PAH feature (along wi...

The HH34 outflow as seen in [FeII]1.64um by LBT-LUCI  

E-print Network

Dense atomic jets from young stars copiously emit in [FeII] IR lines, which can, therefore, be used to trace the immediate environments of embedded protostars. We want to investigate the morphology of the bright [FeII] 1.64um line in the jet of the source HH34 IRS and compare it with the most commonly used optical tracer [SII]. We analyse a 1.64um narrow-band filter image obtained with the Large Binocular Telescope (LBT) LUCI instrument, which covers the HH34 jet and counterjet. A Point Spread Function (PSF) deconvolution algorithm was applied to enhance spatial resolution and make the IR image directly comparable to a [SII] HST image of the same source. The [FeII] emission is detected from both the jet, the (weak) counter-jet, and from the HH34-S and HH34-N bow shocks. The deconvolved image allows us to resolve jet knots close to about 1\\arcsec from the central source. The morphology of the [FeII] emission is remarkably similar to that of the [SII] emission, and the relative positions of [FeII] and [SII] pea...

Geochemistry of the Neoproterozoic metasediments of Malhaq and Um Zariq formations, Kid metamorphic complex, Sinai, Egypt: Implications for source-area weathering, provenance, recycling, and depositional tectonic setting  

NASA Astrophysics Data System (ADS)

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

Polarization entanglement generation at 1.5 um based on walk-off effect due to fiber birefringence  

E-print Network

In this Letter, a linear scheme to generate polarization entanglement at 1.5 um based on commercial polarization maintained dispersion shifted fiber (PM-DSF) is proposed. The birefringent walk-off effect of the pulsed pump light in the PM-DSF provides an effective way to suppress the vector scattering processes of spontaneous four wave mixing. A 90 degree offset of fiber polarization axes is introduced at the midpoint of the fiber to realize the quantum superposition of the two correlated photon states generated by the two scalar processes on different fiber polarization axes, leading to polarization entanglement generation. Experiments of the indistinguishable property on single side and two-photon interference in two non-orthogonal polarization bases are demonstrated. A two photon interference fringe visibility of 89\\pm3% is achieved without subtracting the background counts, demonstrating its great potential in developing highly efficient and stable fiber based polarization-entangled quantum light source at optical communication band.

Mental health problems of undocumented migrants (UMs) in the Netherlands: a qualitative exploration of help-seeking behaviour and experiences with primary care  

PubMed Central

Objective To explore health-seeking behaviour and experiences of undocumented migrants (UMs) in general practice in relation to mental health problems. Design Qualitative study using semistructured interviews and thematic analysis. Participants 15 UMs in the Netherlands, varying in age, gender, country of origin and education; inclusion until theoretical saturation was reached. Setting 4 cities in the Netherlands. Results UMs consider mental health problems to be directly related to their precarious living conditions. For support, they refer to friends and religion first, the general practitioner (GP) is their last resort. Barriers for seeking help include taboo on mental health problems, lack of knowledge of and trust in GPs competencies regarding mental health and general barriers in accessing healthcare as an UM (lack of knowledge of the right to access healthcare, fear of prosecution, financial constraints and practical difficulties). Once access has been gained, satisfaction with care is high. This is primarily due to the attitude of the GPs and the effectiveness of the treatment. Reasons for dissatisfaction with GP care are an experienced lack of time, lack of personal attention and absence of physical examination. Expectations of the GP vary, medication for mental health problems is not necessarily seen as a good practice. Conclusions UMs often see their precarious living conditions as an important determinant of their mental health; they do not easily seek help for mental health problems and various barriers hamper access to healthcare for them. Rather than for medication, UMs are looking for encouragement and support from their GP. We recommend that barriers experienced in seeking professional care are tackled at an institutional level as well as at the level of GP. PMID:25416057

The c2d Spitzer Spectroscopic Survey of Ices Around Low-Mass Young Stellar Objects: I. H2O and the 5-8 um Bands  

E-print Network

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

The Complete Census of 70-um-Bright Debris Disks within the FEPS (Formation and Evolution of Planetary Systems) Spitzer Legacy Survey of Sun-like Stars  

E-print Network

(abbreviated) We report detection with the Spitzer Space Telescope of cool dust surrounding solar type stars. The observations were performed as part of the Legacy Science Program, ``Formation and Evolution of Planetary Systems'' (FEPS). From the overall FEPS sample (Meyer et al. 2006) of 328 stars having ages ~0.003-3 Gyr we have selected sources with 70 um flux densities indicating excess in their spectral energy distributions above expected photospheric emission........ .....The rising spectral energy distributions towards - and perhaps beyond - 70 um imply dust temperatures T_dust 1/3 of the debris sources we find that multiple temperature components are suggested, implying a spatial distribution of dust extending over many tens of AU. Because the disks are dominated by collisional processes, the parent body (planetesimal) belts may be extended as well. Preliminary assessment of the statistics of cold debris around sun-like stars shows that ~10% of FEPS targets with masses between 0.6 and 1.8 Msun and ages between 30 Myr and 3 Gyr exhibit 70 um emission in excess of the expected photospheric flux density. We find that fractional excess amplitudes appear higher for younger stars and that there may be a trend in 70 um excess frequency with stellar mass.

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.

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

NASA Astrophysics Data System (ADS)

The Kid Metamorphic Complex of SE Sinai represents a thick volcano-sedimentary succession that underwent polyphase deformation and greenschist to upper amphibolite facies metamorphism in the NE part of the Arabian-Nubian Shield (ANS). The Malhaq and Um Zariq Formations, the target of this study, occupy roughly the northern half of this complex. The Malhaq Formation records several phases of Ediacaran sedimentation and volcanic activity (615-607 Ma), whereas Um Zariq Formation metasediments are relicts of an older sedimentary sequence (Cryogenian; 8136 Ma). The Malhaq Formation comprises a series of dark gray structureless to schistose felsic to intermediate metavolcanics interbedded and intercalated with fine- to medium-grained foliated mica-rich phyllites and schists, while the Um Zariq Formation is a dominantly metasedimentary sequence, mainly represented by well-bedded metapelitic schists. Malhaq metasediments are enriched in SiO2, CaO and K2O and depleted in TiO2, Al2O3 and K2O relative to those of Um Zariq Formation. Aside from the relatively low Ni and Cr concentrations, compatible transition elements of these metasediments are comparable to average crustal contents. Except for marked Sr depletion, LILEs are around average continental crust values. Pronounced negative Nb-Ta anomalies in all samples, and general enrichment of Um Zariq samples in Th, U, Zr, Ti and Y relative to Malhaq ones are the main features of HFSEs. The REE patterns of all samples are parallel to sub-parallel LREE-enriched, with distinct negative Eu anomalies and weakly fractionated HREE segments. Geochemical investigations have revealed that the source rocks of Malhaq Formation metasediments underwent mild to moderate chemical weathering, whereas those of Um Zariq Formation have suffered severe chemical weathering. These metasediments are predominately derived from felsic to intermediate igneous sources, with a particular slight addition from recycled sedimentary source to the Malhaq Formation metasediments. They are collectively geochemically immature and have suffered minor sedimentary recycling, with the bearing of Malhaq Formation metasediments from advanced degree of sorting and reworking. The Malhaq and Um Zariq metasediments had been originally deposited in a continental arc setting, most probably back-arc basin, despite the wide time span between their individual depositions. Various geochemical evidences imply that the main source from which these two chronologically distinct metasediments (Ediacaran vs. Cryogenian) have been derived from the juvenile (arc-type) Arabian-Nubian Shield crust.

Measurements on CO Concentration and gas temperature at 1.58 um with Tunable Diode Laser Absorption Spectroscopy  

NASA Astrophysics Data System (ADS)

The technique based on tunable diode laser absorption Spectroscopy (TDLAS) has been developed to realize the real-time and dynamic measurement of the combustion-generated pollutants. In this paper the fundamental of concentration and temperature measurement with TDLAS is presented. To validate the method, an experimental system of TDLAS is set up. A simple VCSEL diode without temperature controller is used for direct absorption and WMS setup. Restricted by modulation voltage and noise from diode laser and detector, concentration of 0.2% for 1 m path length can be detected. Temperature measurement in tube furnace is also carried out by CO2 absorption lines near 1.58um, and below 800K the difference between calculation by TDLAS and temperature signal by K-thermocouple is less than 60K. The method to eliminate the effects of the particles is also discussed here. By using three-order polynomial program, the measurement can be not affected by particles and power fluctuation.

The UmGcn5 gene encoding histone acetyltransferase from Ustilago maydis is involved in dimorphism and virulence.  

PubMed

We isolated a gene encoding a histone acetyltransferase from Ustilago maydis (DC.) Cda., which is orthologous to the Saccharomyces cerevisiae GCN5 gene. The gene was isolated from genomic clones identified by their specific hybridization to a gene fragment obtained by the polymerase chain reaction (PCR). This gene (Umgcn5; um05168) contains an open reading frame (ORF) of 1421bp that encodes a putative protein of 473 amino acids with a Mr. of 52.6kDa. The protein exhibits a high degree of homology with histone acetyltransferases from different organisms. Null a2b2 ?Umgcn5 mutants were constructed by substitution of the region encoding the catalytic site with a hygromycin B resistance cassette. Null a1b1 ?Umgcn5 mutants were isolated from genetic crosses of a2b2 ?Umgcn5 and a1b1 wild-type strains in maize. Mutants displayed a slight reduction in growth rate under different conditions, and were more sensitive than the wild type to stress conditions, but more important, they grew as long mycelial cells, and formed fuzz-like colonies under all conditions where wild-type strains grew in the yeast-like morphology and formed smooth colonies. This phenotype was not reverted by cAMP addition. Mutants were not virulent to maize plants, and were unable to form teliospores. These phenotypic alterations of the mutants were reverted by their transformation with the wild-type gene. PMID:25242418

The Y-Band at 1.035 um: Photometric Calibration and the Dwarf Stellar/Sub-Stellar Color Sequence  

E-print Network

We define and characterize a photometric bandpass (called "Y") that is centered at 1.035 um, in between the traditionally classified ``optical'' and ``infrared'' spectral regimes. We present Y magnitudes and Y-H and Y-K colors for a sample consisting mostly of photometric and spectral standards, spanning the spectral type range sdO to T5V. Deep molecular absorption features in the near-infrared spectra of extremely cool objects are such that the Y-H and Y-K colors grow rapidly with advancing spectral type especially from late M through mid L, substantially more rapidly than J-H or H-K which span a smaller total dynamic range. Consistent with other near-infrared colors, however, Y-H and Y-K colors turn blueward in the L6-L8 temperature range with later T-type objects having colors similar to those of warmer M and L stars. Use of the Y-band filter is nonetheless promising for easy identification of low-mass stars and brown dwarfs, especially at young ages. The slope of the interstellar reddening vector within this filter is A_Y = 0.38 x A_V. Reddening moves stars nearly along the YHK dwarf color sequence making it more difficult to distinguish unambiguously very low mass candidate brown dwarf objects from higher mass stars seen, e.g. through the galactic plane or towards star-forming regions. Other diagrams involving the Y-band may be somewhat more discriminating.

Charged particle detection performances of CMOS pixel sensors produced in a 0.18 um process with a high resistivity epitaxial layer  

E-print Network

The apparatus of the ALICE experiment at CERN will be upgraded in 2017/18 during the second long shutdown of the LHC (LS2). A major motivation for this upgrade is to extend the physics reach for charmed and beauty particles down to low transverse momenta. This requires a substantial improvement of the spatial resolution and the data rate capability of the ALICE Inner Tracking System (ITS). To achieve this goal, the new ITS will be equipped with 50 um thin CMOS Pixel Sensors (CPS) covering either the 3 innermost layers or all the 7 layers of the detector. The CPS being developed for the ITS upgrade at IPHC (Strasbourg) is derived from the MIMOSA 28 sensor realised for the STAR-PXL at RHIC in a 0.35 um CMOS process. In order to satisfy the ITS upgrade requirements in terms of readout speed and radiation tolerance, a CMOS process with a reduced feature size and a high resistivity epitaxial layer should be exploited. In this respect, the charged particle detection performance and radiation hardness of the TowerJazz 0.18 um CMOS process were studied with the help of the first prototype chip MIMOSA 32. The beam tests performed with negative pions of 120 GeV/c at the CERN-SPS allowed to measure a signal-to-noise ratio (SNR) for the non-irradiated chip in the range between 22 and 32 depending on the pixel design. The chip irradiated with the combined dose of 1 MRad and 10^13 n_eq/cm^2 was observed to yield a SNR ranging between 11 and 23 for coolant temperatures varying from 15 C to 30 C. These SNR values were measured to result in particle detection efficiencies above 99.5% and 98% before and after irradiation respectively. These satisfactory results allow to validate the TowerJazz 0.18 um CMOS process for the ALICE ITS upgrade.

Spatially Resolved 3 um Spectroscopy of IRAS 22272+5435: Formation and Evolution of Aliphatic Hydrocarbon Dust in Proto-Planetary Nebula  

E-print Network

We present medium-resolution 3 um spectroscopy of the carbon-rich proto-planetary nebula IRAS 22272+5435. Spectroscopy with the Subaru Telescope adaptive optics system revealed a spatial variation of hydrocarbon molecules and dust surrounding the star. The ro-vibrational bands of acetylene (C2H2) and hydrogen cyanide (HCN) at 3.0 um are evident in the central star spectra. The molecules are concentrated in the compact region near the center. The 3.3 and 3.4 um emission of aromatic and aliphatic hydrocarbons is detected at 600--1300 AU from the central star. The separation of spatial distribution between gas and dust suggests that the small hydrocarbon molecules are indeed the source of solid material, and that the gas leftover from the grain formation is being observed near the central star. The intensity of aliphatic hydrocarbon emission relative to the aromatic hydrocarbon emission decreases with distance from the central star. The spectral variation is well matched to that of a laboratory analog thermally annealed with different temperatures. We suggest that either the thermal process after the formation of a grain or the variation in the temperature in the dust-forming region over time determines the chemical composition of the hydrocarbon dust around the proto-planetary nebula.

The ultraviolet spectrum of the gravitational lens candidate UM 425 = QSO 1120+019: Evidence for broad absorption line (BAL) structure  

NASA Technical Reports Server (NTRS)

The UV line profile structure of high-ionization resonance lines found with the International Ultraviolet Explorer (IUE) in the brightest of four multiply imaged sources (images-A) in the candidate gravitational lens UM 425 = QSO 1120+019 indicates broad absorption line (BAL) structure. The deep-broad trough associated with the O IV line extends to velocities approiximately -12,000 km/s, and contains disrete features that suggest multicomponent velocity structure. This structure may include contributions from C IV absorption from the early-type galaxy that is believed to lens UM 425. A strong absorption feature in the blue wing of the Lyman-alpha lambda 1216 emission line may be a Lyman alpha absorption system at a Z(sub Ly alpha) = 1.437 +/- 0.003, or it may be formed by the superposition of the broad N V lambda lambda 1238, 1242 absorption trough on the extended blue emission wing of the QSO Lyman-alpha line. We obtained a redshift of Z(sub QSO) = 1.471 +/- 0.003 from Lyman-alpha lambda 1215, consistent with the redshift found by Meylan and Djorgovski in the optical. The Lyman-alpha line appears unusally weak due to the presence of N V lambda 1240 BAL absorption. A Lyman-limit absorption system at lambda 912 was not observed in the QSO rest frame. The detection of BAL structure in the other weaker ground-state resonance lines of N II (l) and S IV (l) was not found, suggesting these lines are formed in a region that is distinct from the BAL component. Detection of BAL structure in the other fainter images in this system with Hubble Space Telescope (HST) instrumentation, similar to structure observed here in image A, could provide evidence that UM 425 is a gravitational lens.

3.6-7.9 um Photometry of L and T Dwarfs and the Prevalence of Vertical Mixing in their Atmospheres  

E-print Network

We present new L' (3.75 um) photometry of six L and T dwarfs, and M' (4.70 um) photometry of ten L and T dwarfs, observed at Gemini Observatory, and new 3.55, 4.49, 5.73 and 7.87 um photometry of nine L and T dwarfs, obtained with the Spitzer Space Telescope. The sample includes unusually blue and red dwarfs from our near-infrared studies. The data are combined with published L', M' and Spitzer photometry of L and T dwarfs, and trends of colors with spectral type and other colors are examined. Model atmospheres by Marley and Saumon are used to generate synthetic colors for ranges of effective temperature, gravity, grain sedimentation efficiency, metallicity and vertical mixing efficiency. We explore how these parameters affect the mid-infrared colors of L and T dwarfs and find that the data are modelled satisfactorily only if substantial vertical mixing occurs in both L- and T-dwarf atmospheres. The location and range of the L and T dwarf sequences in IRAC color-color and color - magnitude diagrams is also only reproduced if this mixing occurs, with a range of efficiency described by K_zz ~ 10^2-10^6 cm^2/s. The colors of the unusually red dwarfs are best reproduced by non-equilibrium models with low sedimentation efficiency, i.e. thick cloud decks, and those of the unusually blue dwarfs by non-equilibrium models with high sedimentation efficiency, i.e. thin cloud decks. The K-L' and Spitzer [3.55]-[4.49] colors can be used as indicators of effective temperature for L and T dwarfs, but care must be taken to include gravity and metallicity effects for late-T dwarfs and vertical mixing for both late-L and T dwarfs.

Generation of 1.5-um band time-bin entanglement using spontaneous fiber four-wave mixing and planar lightwave circuit interferometers  

E-print Network

This paper reports 1.5-um band time-bin entanglement generation. We employed a spontaneous four-wave mixing process in a dispersion shifted fiber, with which correlated photon pairs with very narrow bandwidths were generated efficiently. To observe two-photon interference, we used planar lightwave circuit based interferometers that were operated stably without feedback control. As a result, we obtained coincidence fringes with 99 % visibilities after subtracting accidental coincidences, and successfully distributed entangled photons over 20-km standard single-mode fiber without any deterioration in the quantum correlation.

[Fe II] 1.64 um Imaging Observations of the Outflow Features around Ultracompact H II Regions in the 1st Galactic Quadrant  

E-print Network

We present [Fe II] 1.644 um features around ultracompact H II regions (UCHIIs) found on a quest for the "footprint" outflow features of UCHIIs---the feature produced by the outflowing materials ejected during the earlier, active accretion phase of massive young stellar objects (MYSOs). We surveyed 237 UCHIIs in the 1st Galactic quadrant, employing the CORNISH UCHII catalog and UWIFE data which is an imaging survey in [Fe II] 1.644 um performed with UKIRT-WFCAM under ~ 0.8" seeing condition. The [Fe II] features were found around five UCHIIs, one of which is of low plausibility. We interpret that the [Fe II] features are shock-excited by outflows from YSOs, and estimate the outflow mass loss rates from the [Fe II] flux, which are ~ 1 x 10^-6 - 4 x 10^-5 Ms yr^-1. We propose that the [Fe II] features might be the "footprint" outflow features, but more studies are required to clarify it. This is based on the morphological relation between the [Fe II] and 5 GHz radio features, the outflow mass loss rate, the trav...

Nesse trabalho apresentado um estudo do contedo de massa do aglomerado de galxias A586 (z = 0.171) bem como sua distribuio espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescpio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posio dos seus arcos gravitacionais (lentes fortes), da medida estatstica da distoro na forma das galxias de fundo (lentes fracas) e atravs da disperso de velocidades de uma amostra de cerca de 30 galxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros mtodos no dependem do estado dinmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura tambm sero includos nessa anlise. Nossos resultados preliminares a partir das tcnicas de lentes fracas, mostram que, supondo que a distribuio de massa desse aglomerado seja a de uma esfera isotrmica, espera-se que ele apresente uma disperso de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores to altos quanto 1680 km s-1. J o estudo dinmico resultou numa disperso de velocidades de ~950 km s-1.

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

NASA Technical Reports Server (NTRS)

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.

Modelling future changes in climate, ozone-depleting substances and ozone precursor emissions using the whole-atmosphere UM-UKCA model  

NASA Astrophysics Data System (ADS)

Using the recently upgraded whole-atmosphere UM-UKCA chemistry-climate model, we investigate the atmospheric response to future changes in a) greenhouse gases under the RCP4.5 and 8.5 scenarios for climate change, b) ozone-depleting substances (ODS) and a recovery of the ozone layer and c) ozone precursor emissions and tropospheric oxidising capacity. In addition, we combine these scenarios in order to explore the interactions between individual perturbations. Within this framework, the coupled stratosphere-troposphere system and whole-atmosphere chemistry allows us to study the impact of changes in composition of the stratosphere on the troposphere and vice versa. We find that by the year 2100: 1) the stratosphere significantly impacts the troposphere via changes in stratosphere-troposphere exchange (STE) but the chemical changes induced in the troposphere do not impact the stratosphere, 2) perturbations are linearly additive with regard to the total ozone column and tropospheric odd oxygen budget, 3) while the Brewer-Dobson Circulation strengthens under climate change (with an increase in the DJF 70hPa tropical upwards mass flux of ~20% at RCP4.5 and exceeding 30% at RCP8.5), this strengthening is offset by ozone recovery (which on its own leads to a decrease in the mass flux of ~10%) and 4) tropospheric ozone decreases given mitigation of its precursor emissions (with a 10% decrease in ozone burden) but this can be offset by climate change at both RCP4.5 and 8.5 and stratospheric ozone recovery (increasing the burden by 6-13%).

A novel solution to the gated x-ray detector gain droop problema)  

NASA Astrophysics Data System (ADS)

Microchannel plate (MCP), microstrip transmission line based, gated x-ray detectors used at the premier ICF laser facilities have a drop in gain as a function of mircostrip length that can be greater than 50% over 40 mm. These losses are due to ohmic losses in a microstrip coating that is less than the optimum electrical skin depth. The electrical skin depth for a copper transmission line at 3 GHz is 1.2 ?m while the standard microstrip coating thickness is roughly half a single skin depth. Simply increasing the copper coating thickness would begin filling the MCP pores and limit the number of secondary electrons created in the MCP. The current coating thickness represents a compromise between gain and ohmic loss. We suggest a novel solution to the loss problem by overcoating the copper transmission line with five electrical skin depths (6 ?m) of Beryllium. Beryllium is reasonably transparent to x-rays above 800 eV and would improve the carrier current on the transmission line. The net result should be an optically flat photocathode response with almost no measurable loss in voltage along the transmission line.

Elder abuse and the dentists' awareness and knowledge of the problem--a national survey.  

PubMed

A national sample of 1,775 Canadian dentists, representing 13.2 per cent of all Canadian dentists, were evaluated via a mailed questionnaire about their knowledge, awareness of, and experiences with victims of elder abuse and/or neglect. In all, 83.3 per cent of respondents were aware, to varying extents, of elder abuse or neglect. Of the dentists observing a patient suspected to have been a victim of neglect or abuse, 40.6 per cent reported incidents of neglect, while physical abuse was seen 59.4 per cent of the time. The types of neglect most frequently observed included: neglect of personal hygiene (31.8 per cent), failure to provide adequate medical/dental care (30.2 per cent), and failure to provide adequate supervision (20.1 per cent). The most frequently reported signs of physical abuse were bruises and welts (21.8 per cent), broken denture prostheses (12.1 per cent), fractured and avulsed teeth (11.5 per cent), and abrasions and lacerations (10.3 per cent). Where abuse was observed, dentists provided dental treatment in 53.2 per cent of the cases and made emergency medical referrals in 20.3 per cent of the cases. This study demonstrates that dentists have identified cases of abuse and/or neglect, and therefore should be consulted in the abuse/neglect identification and assessment process. PMID:8252450

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.

Aportes del Aprendizaje Basado en Problemas (ABP) en la ensenanza de la Fisiologia Animal en un programa de Zootecnia  

NASA Astrophysics Data System (ADS)

Based on difficulties observed on the subject of technical-scientific conceptualization and the integration of theory and practice in learning animal physiology for students in the Animal Science program at the National University of Colombia in Medellin, this research paper proposes a problem-based learning strategy founded on the method of Problem Based Learning (PBL), applied specifically to the issues of thermoregulation and physiological stress in domestic animals. In this case study, a sample size of eight students was presented with a pedagogical problem during the first session that would then be solved during the course. In order to evaluate the process, three surveys were conducted called Level Test Formulations (NF) performed at different times of the trial: one before beginning the topic (NF 1), one after three theoretical classes had been given and before beginning the fieldwork (NF 2), and another one after the end of the process (NF 3). Finally, individual interviews were conducted with each student to know the students' perceptions regarding the method. The information obtained was subjected to a qualitative analysis and categorization, using the QDA Miner program which reviewed and coded texts from the surveys and individual interviews, supplemented in turn, by field observation, analyzing the conceptual change, the theory-practice relationship and the correlation between the variables and categories established. Among the main results obtained, it should be noted that following the implementation of PBL in this Animal Physiology course, support for conceptual change was demonstrated and the formulated problem served as a connector between theory and practice. Moreover, there was a fusion of prior knowledge with newly acquired knowledge, meaningful learning, improvement in the level of conceptualization and an increase in the scientificness of definitions; it also led to problem-solving and overcoming epistemological obstacles such as multidisciplinarity and nonlinearity. As a result of this research, it is recommended that this method be evaluated in other topics related to Animal Physiology, in other sciences, in larger sample sizes, as well as to address the issue of evaluation applied directly to this method. Key words: Problem Based Learning (PBL), conceptual change, integration of theory and practice, significatif learning, animal physiology, thermoregulation, physiological stress.

The airbag problema potential culprit for bench-to-bedside translational efforts: relevance for Alzheimers disease  

PubMed Central

For the last 20years, the amyloid cascade hypothesis has dominated research aimed at understanding, preventing, and curing Alzheimers disease (AD). During that time researchers have acquired an enormous amount of data and have been successful, more than 300 times, in curing the disease in animal model systems by treatments aimed at clearing amyloid deposits. However, to date similar strategies have not been successful in human AD patients. Hence, before rushing into further clinical trials with compounds that aim at lowering amyloid-beta (A?) levels in increasingly younger people, it would be of highest priority to re-assess the initial assumption that accumulation of A? in the brain is the primary pathological event driving AD. Here we question this assumption by highlighting experimental evidence in support of the alternative hypothesis suggesting that APP and A? are part of a neuronal stress/injury system, which is up-regulated to counteract inflammation/oxidative stress-associated neurodegeneration that could be triggered by a brain injury, chronic infections, or a systemic disease. In AD, this protective program may be overridden by genetic and other risk factors, or its maintenance may become dysregulated during aging. Here, we provide a hypothetical example of a hypothesis-driven correlation between car accidents and airbag release in analogy to the evolution of the amyloid focus and as a way to offer a potential explanation for the failure of the AD field to translate the success of amyloid-related therapeutic strategies in experimental models to the clinic.

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.

Fluoride hosts are favorable due to the long lifetime of the upper laser level. The calculated slope efficiency in Er:YLF approaches 56% when pumping at 970 nm. This value clearly exceeds

Use of 3-um laser radiation in middle ear surgery  

NASA Astrophysics Data System (ADS)

An inner ear model was used to demonstrate thermal and mechanical effects occurring during Erbium laser stapedotomy. Results of inverse schlieren optical flash photography and time resolved pressure amplitude measurements indicate the existence of safe laser parameters for stapes foot plate perforation. Due to the high absorption of 3 micrometers radiation in water, efficient bone ablation and precise fenestration with small thermally damaged zones is achieved. Pressure transients caused by the explosive ablation process correlate with the spiking of the laser intensity. The energy of a laser pulse, directly applied into the perilymph through an already existing perforation, creates a vapor channel which afterwards collapses, sending out a strong pressure transient. The maximal amplitude of this pressure transient depends on the geometry and dynamics of the vapor channel and is several times stronger than the pressure amplitudes generated by the bone ablation process. This study shows that no permanent hearing loss or damage of inner ear structures is expected using an Erbium laser fluence of 10 J/cm2.

Predictive process control for sub-0.2-um lithography  

NASA Astrophysics Data System (ADS)

An advanced control system providing modeling and predictive data simulation for pass-fail criteria of overlay production control has been used in 0.18 micrometer Design Rule production facilities for over a year. During this period overlay was measured on both product wafers and during periodic process qualification tests. The resulting raw data is modeled using exposure tool specific and layer-focused models. Modeled results, measured process statistics and tool signatures are combined in a real-time simulation to calculate the true overlay distribution over the entire wafer and lot. All results and raw data are automatically gathered and stored in a database for on-going analysis. In this manner, tool, product technology and process performance data are gathered for every overlay process-step. The data provides valuable insights into not only tool stability but also the process- step characteristic errors that contribute to the overlay spectrum of distortions. Data gathered in this manner is very stable and can be used to predict a feed-forward correction for all correctable coefficients. The technique must take into consideration algorithm modeled coefficient variations resulting from: (1) Reticle pattern-to-alignment mark design errors. (2) Process film variations. (3) Tool-to-tool static matching. (4) Tool-to-tool dynamic matching errors which are match-residual, process or time induced. This extensive database has resulted in a method of conducting Predictive Process Control (PPC) for overlay lithography within an advanced semiconductor line. Using PPC the wafer production facility experiences: (1) Improved Yield: Lots are always exposed with optimum setup. Optimized setups reduce rework levels and therefore wafer handling. (2) Capacity Improvement: Elimination of rework tacitly improves capacity in the facility. WIP is also simplified because lots do not have to wait for a dedicated exposure tool to become available. (3) Dynamic MatchingTM: Matching of multiple exposure tools is continuously monitored by the use of the feedback loop. Tool precision can be monitored as well as the setup systematic offsets. In this manner, the need to remove an exposure tool from production for match-maintenance can be predicted and scheduled. Residual matching errors can also be removed from the production cycle. The benefits of full production lot modeling and the contributors to production errors are presented. Process and Tool interactions as well as control- factor coefficient stability indicate the level of control to be well beyond manual methods. Calculations show that these contributors are predictable, stable and are a necessary tool for competitive sub-0.2 micron production. An analysis of the overlay error sources within two facilities results in consistent facility process response and a well-defined error budget derivation. From this analysis, the control added to semiconductor overlay is shown capable of extending mix-and- match exposure tool operations in production down to 0.12 micrometer design rules.

High-resolution superconducting x-ray spectrometers with an active area of 282 um x 282 um  

SciTech Connect

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

Datirovka zvezdnogo kataloga Ptolemeya po sobstvennym dvizheniyam: tysyacheletnyaya problema reshena %t Dating Ptolemy's star catalogue based on proper motions: the thousand-year-old problem solved  

NASA Astrophysics Data System (ADS)

The thousand-year-old problem of the origin of the star catalogue included in Ptolemy's "Almagest" is considered. The dilemma whether stellar coordinates were based on Hipparchus' or Ptolemy's observations has arisen long ago, because the 1 degree error in ecliptic longitudes may be explained either by Ptolemy's error in the initial longitudes of the Sun, or by the fact that Ptolemy adopted the original Hipparchus' coordinates and transformed them to a 265-year later epoch using an erroneous constant for precession. In fact, only indirect evidence for the Hipparchan origin of most of the coordinates was available so far, and most specialists considered the issue still to be resolved. We have successfully applied a new approach based on stellar proper motions. The time-dependent mutual distances in the configurations including 8 fast stars yield an epoch of -53 130 B.C., whereas the bulk method based on an analysis of the Almagest minus computed coordinate differences for 40 fastest stars yields an epoch of -90 120 B.C. Standard errors in the ancient ecliptic longitudes and latitudes are found to be ?(?cos?) = 18' and ?? = 13', respectively. It is concluded that the stellar coordinates in the Almagest catalogue were observed during Hipparchus' lifetime and that Ptolemy's authorship claim can be rejected at a 94% significance level. Ptolemy's assertion that "we observed as many stars as we could sight down to the sixth magnitude" might simply imply that he found each star of the original catalogue to be near its position in the sky given by Hipparchus, and then adopted Hipparchus' coordinates as measured by a more skilled observer.

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.

Problema vizual'noj registratsii nablyudenij v opticheskoj astronomii XVII-XVIII vekov %t Problem of visual registration of observations in optical astronomy in the 17th-18th centuries  

NASA Astrophysics Data System (ADS)

This paper attempts to explain the growth of optical astronomy as a result of more general social and cultural change in European life during the two post-Renaissance centuries. It shows how the introduction of optical instruments into astronomical work was accompanied (and partly conditioned) by a few nonastronomical practices, such as collecting unusual things and their images, producing illusionary effects by means of optical devices, manufacturing pictures that could disturb the common visual perception, etc. The paper draws particular attention to the practices of manipulation with visual images that could help to introduce "illusionary" optical knowledge into making "true" drawings from natural objects, including celestial ones. In this way, the formation of new astronomical language can be understood as closely connected to the explicit formulation of technological instructions and legal rules for making copies from natural objects, as well as the general development of printing production and broadening of the market of printed illustrations. These often not enough co-ordinated practices stipulated the shift of optical astronomy into a significant part of seigniorial culture, where it obtained recognition as an essentially new and elite knowledge, associated with particular technological vigilance. During the transition of European monarchies into the absolutist social order, astronomy, on a level with other court services, assumed a shape of professional occupation supplied with certain monetary salaries, a stable position in official hierarchy, and supreme privileges. This was the way by which astronomy merged with the other natural studies and became one of the publicly recognised scientific disciplines.

Lunnoe zatmenie -330, sept. 20 i problema izmereniya dolgoty v antichnoj geografii %t The -330, Sept. 20 lunar eclipse and the problem of the determination of longitude in ancient geography  

NASA Astrophysics Data System (ADS)

The attempt to reconstruct the Hipparchus system of is proposed. The offered analysis of certain passages in the treatises of Ptolemy, Pliny, and Strabo allows to trace the latent semantic connection between them and to advance a hypothesis to clarify it. Ptolemy's passage (sect. 3) states Hipparchus to propose in his geography a certain system of meridians and to use the -330, Sept. 20 eclipse to determine the relative longitudes of Arbela and Carthage. Pliny's evidence (4) shows that Hipparchus must have known about the observation of this eclipse from Sicily, which demands to situate this island far eastward of Carthage. Strabo's data (5) confirm that Hipparchus, while criticising Eratosthenes, suggested situating Sicily far eastward of Carthage. Ptolemy's data (6) show that Marinus, whose work Ptolemy's geography was based on, in his early redaction, must situate Sicily farther eastward than in the final variant. Posidonius' passage (7) demonstrates the latitude of Sicily in Ptolemy's geography to go back to Hipparchus. In "Almagest" (9) the longitude of Babylon (relative to Alexandria) is directly ascribed to Hipparchus and the longitude of Rome agrees with that of Sicily in Pliny's evidence. The data of Ptolemy's geography (9.3-9.5) permit that Arbela and Babylon were situated on the same meridian initially. All these enable us to suggest that Hipparchus determined the longitudes not only of Arbela and Babylon, but also of Babylon and Sicily, Alexandria and Rome.

Tungsten CMP process characterization for sub-0.35-um micron technology  

NASA Astrophysics Data System (ADS)

The chemical mechanical polishing (CMP) of tungsten has been recognized as an enabling technology for sub-half-micron multi-level interconnect. There are many technical challenges to be resolved when incorporating tungsten CMP into the manufacturing line. In this paper, key issues related to the tungsten CMP process--oxide erosion, plug recess, oxide thinning, surface roughness, microscratches, contamination, photolithographic alignment, metal line bridging, via resistance and device yield--were studied for three different types of slurries. The variables studied include pattern density, glue layer thickness, overpolish time and underlying oxide type. Atomic force microscopy, scanning electron microscope and long-scan surface profiler were used. Oxide thinning and erosion were found to depend strongly on slurry type and all the variables studied. With optimized polishing parameters and integration scheme, the tungsten CMP process has enough processing window for manufacturing.

Distribution of benthic foraminifers (>125 um) in the surface sediments of the Arctic Ocean  

USGS Publications Warehouse

Census data on benthic foraminifers (>125 ?m) in surface sediment samples from 49 box cores are used to define four depth-controlled biofacies, which will aid in the paleoceanographic reconstruction of the Arctic Ocean. The shelf biofacies contains a mix of shallow-water calcareous and agglutinated species from the continental shelves of the Beaufort and Chukchi Seas and reflects the variable sedimentologic and oceanic conditions of the Arctic shelves. The intermediate-depth calcareous biofacies, found between 500 and 1,100 meters water depth (mwd), contains abundant Cassidulina teretis , presumably indicating the influence of Atlantic-derived water at this depth. In water depths between 1,100 and 3,500 m, a deepwater calcareous biofacies contains abundant Oridorsalis umbonatus . Below 3,500 mwd, the deepwater mixed calcareous/agglutinated biofacies of the Canada, Makarov, and Eurasian Basins reflects a combination of low productivity, dissolution, and sediment transport. Two other benthic foraminiferal species show specific environmental preferences. Fontbotia wuellerstorfi has a depth distribution between 900 and 3,500 mwd, but maximum abundance occurs in the region of the Mendeleyev Ridge. The elevated abundance of F. wuellerstorfi may be related to increased food supply carried by a branch of Atlantic water that crosses the Lomonosov Ridge near the Russian Continental Shelf. Triloculina frigida is recognized to be a species preferring lower slope sediments commonly disturbed by turbidites and bottom currents. INTRODUCTION At present, our understanding of the Arctic Ocean lags behind our understanding of other oceans, and fundamental questions still exist about its role in and response to global climate change. The Arctic Ocean is particularly sensitive to climatic fluctuations because small changes in the amounts of sea-ice cover can alter global albedo and thermohaline circulation (Aagaard and Carmack, 1994). Numerous questions still exist regarding the nature and timing of paleoclimatic events in the Arctic Ocean. In order to attempt to answer some of these questions, baseline studies are imperative. This report discusses the distribution of benthic foraminifers in surface sediment samples from 49 box cores (figs. 1 and 2, table 1) collected by the U.S. Geological Survey (USGS) with the assistance of the U.S. Coast Guard (USCG). A modern data set of benthic foraminiferal distribution is necessary for interpreting the paleoclimatic and oceanographic history of the Arctic Ocean.

250 um inner diameter hollow waveguide for Er:YAG laser radiation  

NASA Astrophysics Data System (ADS)

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

Application of 2-um wavelength holmium lasers for treatment of skin diseases  

NASA Astrophysics Data System (ADS)

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

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 changesglacial 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-intensity, short pulse (1 ps), laser-plasma interaction at 1 um  

NASA Astrophysics Data System (ADS)

We present studies of high-intensity laser-plasma interactions using a 1-ps, 1.053-pm laser. It is currenily operated in a single-pulse mode with energies up to -100 mJ and focused intensities up to mid-1015 W/cm2. We have measured the absorption of laser light in plasmas produced during interactions with various moderate targets using an Ulbricht's sphere. Charge collectors were used to study the characteristics of the ion expansion. X-ray and XUV spectroscopy were used to measure the spectral emission from the plasmas. These results are compared to 1-D hydrodynamic code (LILAC) simulations. LILAC has been modified to improve its validity for short-pulse interactions but it is still found that the absorption is underestimated. Potential explanations, including suprathermal electron generation, are discussed.

Analysis for dispersion-induced composite frequency distortion of AM signal at 1.5 um  

NASA Astrophysics Data System (ADS)

The frequency domain analysis for nonlinear distortion of 1.5 micrometers AM signal transmitted in single mode fiber is presented which drives, for the first time in our knowledge, approximate analytical solutions for composite-second order (CSO) and composite-triple beat (CTB) distortion. The results here can be applied conveniently to engineering, and are somewhat better than those given by Bergmann et al (1990), by Phillips et al (1991) or by Kuo (1993). All their expressions for CSO or CTB are dependent on a product of fiber dispersion coefficient times laser chirp rate, that causes a problematic inference fiber dispersion cannot cause nonlinear frequency distortion of pure AM signal (without laser chirping). Our expressions and curves for calculating CSO and CTB in practical CATV signal transmission at 1.5 micrometers are indicated, and also compared with the published theoretical and experimental results. Computation shows that pure AM signal suffers from fiber dispersion as well, the CSO and CTB of which are both proportional to second power of dispersion phase-shift angle, but proportional to first power and second power of AM index respectively. The curves of CSO and CTB versus transmission distance are also presented. It turns out that the results here include distortion effect of higher order.

Spin-on-glass/phosphosilicate glass etchback planarization process for 1.0 um CMOS technology  

NASA Astrophysics Data System (ADS)

Studies of SOG/oxide planarization etch back processes have shown that micro loading effects play a major role in shifting selectivity of the etch at the SOG/oxide interface thereby causing the wafer to lose its asspun level of pianarization. This paper describes recent work performed to improve an SOG/PSG etchback planarizatiori process used in production on 1. O/m geome tries. The etchback planarization process is run in a Drytek Model 616 etch system using a triode chamber. In the study the effect of CHF3 C2F6 SF6 and CF4 gas chemistries on etch planarization are examined. Results of these experiments and how they compare to the original production etchback planarization process are discussed.

NASA Astrophysics Data System (ADS)

A compact (2'6' X 2'5' X 1'1') 3.30 - 3.47-micrometers DIAL lidar has been constructed for base remediation and chemical monitoring. The lidar system is designed for short range (0.5 km maximum) aerosol backscatter detection of light hydrocarbons with sensitivities at parts-per-million level in a 30-m ranging bin. The system can also operate in the topographic mode. The on-line and off-line wavelengths are produced sequentially using a dual crystal intra-cavity KTA OPO. Detection is by means of an 8-in Newtonian telescope coupled to a Stirling cycle cooled InSb detector. The system incorporates an onboard digital signal processor and controller, operator's interface is furnished by a laptop PC. Results of initial tests using diesel fuel and a solvent are presented.

VizieR Online Data Catalog: WISE and HIP 22um excess stars (Wu+, 2013)  

NASA Astrophysics Data System (ADS)

In this paper, we present a catalog that includes 141 bright candidates (<=10.27mag, V band) showing an excess of infrared (IR) at 22?m. Of these 141 candidates, 38 stars are known IR-excess stars or disks, 23 stars are double or multiple stars, and 4 are Be stars while the remaining more than 70 stars are identified as 22 ?m excess candidates in our work. The criterion for selecting candidates is Ks-[22]?m. All these candidates are selected from the Wide-field Infrared Survey Explorer all-sky data cross-correlated with the Hipparcos main catalog and the likelihood-ratio technique is employed. Considering the effect of background, we introduce the IRAS 100?m level to exclude the high background. We also estimate the coincidence probability of these sources. In addition, we present the optical to mid-IR spectral energy distributions and optical images for all the candidates, and give the observed optical spectra of six stars with the National Astronomical Observatories, Chinese Academy of Sciences' 2.16m telescope. To measure for the amount of dust around each star, the fractional luminosity is also provided. We also test whether our method of selecting IR-excess stars can be used to search for extra-solar planets; we cross-match our catalog with known IR-excess stars with planets but found no matches. Finally, we give the fraction of stars showing excess IR for different spectral types of main-sequence stars. (2 data files).

Alice's adventures in um-derland: Psycholinguistic sources of variation in disfluency production  

PubMed Central

This study tests the hypothesis that three common types of disfluency (fillers, silent pauses, and repeated words) reflect variance in what strategies are available to the production system for responding to difficulty in language production. Participants' speech in a storytelling paradigm was coded for the three disfluency types. Repeats occurred most often when difficult material was already being produced and could be repeated, but fillers and silent pauses occurred most when difficult material was still being planned. Fillers were associated only with conceptual difficulties, consistent with the proposal that they reflect a communicative signal whereas silent pauses and repeats were also related to lexical and phonological difficulties. These differences are discussed in terms of different strategies available to the language production system. PMID:25339788

Blazar Studies with GLAST: Synchro-Compton Analysis of Flat Spectr um Radio Quasars  

E-print Network

We extend a method for modeling synchrotron and synchrotron self-Compton radiations in blazar jets to include external Compton processes. The basic model assumption is that the blazar radio through soft X-ray flux is nonthermal synchrotron radiation emitted by isotropically-distributed electrons in the randomly directed magnetic field of outflowing relativistic blazar jet plasma. Thus the electron distribution is given by the synchrotron spectrum, depending only on the Doppler factor and mean magnetic field, given that the comoving emission region size scale. Generalizing the approach of Georganopoulos, Kirk, and Mastichiadis (2001) to arbitrary anisotropic target radiation fields, we use the electron spectrum implied by the synchrotron component to derive accurate Compton-scattered $\\gamma$-ray spectra throughout the Thomson and Klein-Nishina regimes for external Compton scattering (ECS) processes. We derive and calculate accurate $\\gamma$-ray spectra produced by relativistic electrons that Compton-scatter (...

NASA Astrophysics Data System (ADS)

We have developed a method for patterning sub-micrometer gates with T-shaped cross sections, which may be applied to manufacture high performance field effect transistors (FETs). The technique employs two exposures at the KrF excimer laser wavelength (248 nm). The first exposure uses a phase-shifting mask to pattern 0.1 micrometers isolated spaces. The resist used for the second exposure absorbs the 248 nm radiation strongly enough to produce a profile suitable for lift-off patterning.

Lithography window check before mask tape-out in sub 0.18um technology  

NASA Astrophysics Data System (ADS)

Lithography Rule Check (LRC) becomes a necessary procedure for post OPC in 0.15?m LV and below technology in order to guarantee mask layout correctness. LRC uses a process model to simulate the mask pattern and compare its performance to the desired layout. When the results are out of specified tolerances, LRC will generate error flags as weak points to trigger further checks. This paper introduces LRC to detect the weak points even in non-OPC employed circuit layout such as 0.18?m to 0.15?m process. LRC is more important for semiconductor foundry since there are diverse design layouts and shrinks in production. This diversity leads to the possibility of problematic structures reaching the reticle. In this work, LRC is added as a necessary step in tape-out procedure for the sub 0.18?m process nodes. LRC detected weak points such as low or excessive contrast sites, high MEEF areas and small process window features, then modified the layout according to check results. Our work showed some mask related potential problems can be avoided by LRC in even non model based OPC process and therefore guarantee improved product yield.
