Which prior knowledge? Quantification of in vivo brain 13C MR spectra following 13C glucose infusion using AMARES.  


The recent developments in high magnetic field 13C magnetic resonance spectroscopy with improved localization and shimming techniques have led to important gains in sensitivity and spectral resolution of 13C in vivo spectra in the rodent brain, enabling the separation of several 13C isotopomers of glutamate and glutamine. In this context, the assumptions used in spectral quantification might have a significant impact on the determination of the 13C concentrations and the related metabolic fluxes. In this study, the time domain spectral quantification algorithm AMARES (advanced method for accurate, robust and efficient spectral fitting) was applied to 13 C magnetic resonance spectroscopy spectra acquired in the rat brain at 9.4 T, following infusion of [1,6-(13)C2 ] glucose. Using both Monte Carlo simulations and in vivo data, the goal of this work was: (1) to validate the quantification of in vivo 13C isotopomers using AMARES; (2) to assess the impact of the prior knowledge on the quantification of in vivo 13C isotopomers using AMARES; (3) to compare AMARES and LCModel (linear combination of model spectra) for the quantification of in vivo 13C spectra. AMARES led to accurate and reliable 13C spectral quantification similar to those obtained using LCModel, when the frequency shifts, J-coupling constants and phase patterns of the different 13C isotopomers were included as prior knowledge in the analysis.

Evidence for variation in the number of functional gene copies at the AmaR locus in Chinese hamster cell lines.  


The hypothesis of functional hemizygosity has been examined for the alpha-amanitin resistant (AmaR, a codominant marker) locus in a series of Chinese hamster cell lines. AmaR mutants were obtained from different cell lines, e.g., CHO, DHW, M3- 1 and CHO-Kl, at similar frequencies. After fractionation of different RNA polymerase activities in the extracts by chromatographic procedures, the sensitivity of the mutant RNA polymerase II towards alpha-amanitin was determined. While all of the RNA polymerase II activity in mutant CHO and CHO-Kl lines became resistant to alpha-amanitin inhibition, only about 50% of the activity is highly resistant in AmaR mutants of CHW and M3- 1 cell lines. The remaining activity in the latter cell lines shows alpha-amanitin sensitivity similar to that seen with the wild-type enzyme. This behaviour is similar to that observed with a 1:1 mixture of resistant and sensitive enzymes from CHO cells. These results, therefore, strongly indicate that while only one functional copy of the gene affected by alpha-amanitin is present in CHO and CHO-Kl cells, two copies of this gene are functional in the CHW and M3-1 cell lines.

Location of the Norma transient with the HEAO 1 scanning modulation collimator. [X ray source in Norma Constellation  

NASA Technical Reports Server (NTRS)

A precise position has been obtained for an X-ray transient source in Norma. The location uncertainty includes a variable star previously suggested to be the optical counterpart. This transient is associated with the steady X-ray source MX 1608-52 and probably with an X-ray burst source. A binary system containing a low-mass primary and a neutron-star or black-hole secondary of a few solar masses is consistent with the observations.

The interstellar (C-12)/(C-13) ratio toward Mu Normae  

SciTech Connect

In this paper, the (C-12)/(C-13) ratio in the interstellar cloud toward the star Mu Normae (HD 149038) is determined by estimating the abundance of (C-13)H(+) relative to (C-12)H(+). The equivalent widths of the lines for these ions were determined at 4232 and 3957 A. For the (C-12)H(+) lines, these values were 26.988 + or - 0.108 mA at 4232 A and 15.561 + or - 0.250 mA, respectively, and for (C-13)H(+) the corresponding values were 0.556 + or - 0.0 mA and 0.202 + or - 0.171 mA. The (C-12)/(C-13) ratio obtained from the 4232 A line was 56.9 + or - 6.4, while that from the 3957 A line was 85 + or - 72. 19 refs.

NuSTAR Observations of the Norma Arm Region  

NASA Astrophysics Data System (ADS)

One of the Galactic regions being surveyed by NuSTAR covers a 2 degree x 0.8 degree region of the Norma Arm that was observed with Chandra in 2011. This region was selected because its recent star formation and large number of OB associations make it a good place to search for and study X-ray sources associated with massive stars, such as high-mass X-ray binaries (HMXBs) and colliding wind binaries (CWBs). For the vast majority of sources in this region, the Chandra data are insufficient for constraining their individual spectral parameters and identifying their physical nature, but combining NuSTAR and Chandra data provides strong constraints on their X-ray properties. Roughly a third of the area surveyed by Chandra has been observed with NuSTAR to date, and we present preliminary results identifying the hard X-ray sources observed by both telescopes. We have obtained near-infrared spectra of the counterparts of some of these X-ray sources, which also facilitate their identifications. Although our analysis is ongoing, a significant fraction of sources appear to be intermediate polars, some are likely CWBs and HMXBs, and one may be a black hole binary.

The Norma Arm Region Chandra Survey Catalog: X-Ray Populations in the Spiral Arms  

NASA Astrophysics Data System (ADS)

We present a catalog of 1415 X-ray sources identified in the Norma Arm Region Chandra Survey (NARCS), which covers a 2 0.8 region in the direction of the Norma spiral arm to a depth of ?20 ks. Of these sources, 1130 are point-like sources detected with >=3? confidence in at least one of three energy bands (0.5-10, 0.5-2, and 2-10 keV), five have extended emission, and the remainder are detected at low significance. Since most sources have too few counts to permit individual classification, they are divided into five spectral groups defined by their quantile properties. We analyze stacked spectra of X-ray sources within each group, in conjunction with their fluxes, variability, and infrared counterparts, to identify the dominant populations in our survey. We find that ~50% of our sources are foreground sources located within 1-2 kpc, which is consistent with expectations from previous surveys. Approximately 20% of sources are likely located in the proximity of the Scutum-Crux and near Norma arm, while 30% are more distant, in the proximity of the far Norma arm or beyond. We argue that a mixture of magnetic and nonmagnetic cataclysmic variables dominates the Scutum-Crux and near Norma arms, while intermediate polars and high-mass stars (isolated or in binaries) dominate the far Norma arm. We also present the cumulative number count distribution for sources in our survey that are detected in the hard energy band. A population of very hard sources in the vicinity of the far Norma arm and active galactic nuclei dominate the hard X-ray emission down to fX ? 1014 erg cm2 s1, but the distribution curve flattens at fainter fluxes. We find good agreement between the observed distribution and predictions based on other surveys.

Investigating CXOU J163802.6-471358: A New Pulsar Wind Nebula in the Norma Region?  

NASA Astrophysics Data System (ADS)

We present the first analysis of the extended source CXOU J163802.6-471358, which was discovered serendipitously during the Chandra X-ray survey of the Norma region of the Galactic spiral arms. The X-ray source exhibits a cometary appearance with a point source and an extended tail region. The complete source spectrum is fitted well with an absorbed power law model and jointly fitting the Chandra spectrum of the full source with one obtained from an archived XMM-Newton observation results in best fit parameters N H =1.5^{+0.7}_{-0.5}\\times 10^{23}\\, cm{^{-2}} and \\Gamma =1.1^{+0.7}_{-0.6} (90% confidence uncertainties). The unabsorbed luminosity of the full source is then L_X\\sim 4.8\\times 10^{33}d_{10}^2 erg s-1 with d 10 = d/10 kpc, where a distance of 10 kpc is a lower bound inferred from the large column density. The radio counterpart found for the source using data from the Molonglo Galactic Plane Survey epoch-2 shows an elongated tail offset from the X-ray emission. No infrared counterpart was found. The results are consistent with the source being a previously unknown pulsar driving a bow shock through the ambient medium.

Abundant Molecular Gas and Inefficient Star Formation in Intracluster Regions: Ram Pressure Stripped Tail of the Norma Galaxy ESO137-001  

NASA Astrophysics Data System (ADS)

For the first time, we reveal large amounts of cold molecular gas in a ram-pressure-stripped tail, out to a large "intracluster" distance from the galaxy. With the Actama Pathfinder EXperiment (APEX) telescope, we have detected 12CO(2-1) emission corresponding to more than 109 M ? of H2 in three H? bright regions along the tail of the Norma cluster galaxy ESO 137-001, out to a projected distance of 40 kpc from the disk. ESO 137-001 has an 80 kpc long and bright X-ray tail associated with a shorter (40 kpc) and broader tail of numerous star forming H II regions. The amount of ~1.5 108 M ? of H2 found in the most distant region is similar to molecular masses of tidal dwarf galaxies, though the standard Galactic CO-to-H2 factor could overestimate the H2 content. Along the tail, we find the amount of molecular gas to drop, while masses of the X-ray-emitting and diffuse ionized components stay roughly constant. Moreover, the amounts of hot and cold gas are large and similar, and together nearly account for the missing gas from the disk. We find a very low SFE (?dep > 1010 yr) in the stripped gas in ESO 137-001 and suggest that this is due to a low average gas density in the tail, or turbulent heating of the interstellar medium that is induced by a ram pressure shock. The unprecedented bulk of observed H2 in the ESO 137-001 tail suggests that some stripped gas may survive ram pressure stripping in the molecular phase. Based on observations made with ESO telescopes at La Silla Paranal Observatory under program ID 088.B-0934.

Mandibular shape analysis in fossil hominins: Fourier descriptors in norma lateralis.  


Biological shape can be defined as the boundary of a form in 2-space (R(2)). An earlier study (Lestrel et al., 2010, HOMO-J. Comp. Hum. Biol.) of the cranial vault found that there were statistically significant differences between each of the three groups: H. erectus, H. heidelbergensis, and H. neanderthalensis compared with H. sapiens. In contrast, there was no statistically significant difference among the first three groups. These results suggest that these three groups may have formed single evolving lineage while H. sapiens represents a separate evolutionary development. The purpose of the current research was to discern if the mandible reflected a similar pattern as the cranial vault data. This study used lateral jpeg images of the mandible. Five fossil samples were used: A. robustus (n=7), H. erectus (n=12), H. heidelbergensis (n=4), H. neanderthalensis (n=22) and H. sapiens (n=61). Each mandible image was pre-processed with Photoshop Elements. Each image was then submitted to a specially written routine that digitized the 84 points along the mandible boundary. Each mandible was fitted with elliptical Fourier functions (EFFs). Procrustes superimposition was imposed to insure minimum shape differences. The mandible results largely mirrored the earlier cranial vault study with one exception. Statistically significant results were obtained for the mandible between the H. erectus and H. neanderthalensis samples in contrast to the earlier cranial vault data. F-tests disclosed that the statistical significance was limited to the anterior symphysis of the mandible. This mosaic pattern may be explained by the reduction in prognathism with the concomitant if rudimentary development of the chin as seen in H. neanderthalensis compared to H. erectus. PMID:23769600

We report molecular line and dust continuum observations, made with the Swedish-ESO Submillimeter Telescope, toward four young high-mass star-forming regions associated with highly luminous (L>6x10{sup 5}L{sub odot}) Infrared Astronomical Satellite sources (15290-5546, 15502-5302, 15567-5236, and 16060-5146). Molecular emission was mapped in three lines of CS (J = 2 -> 1, 3 -> 2, and 5 -> 4), two lines of SiO (J = 2 -> 1 and 3 -> 2), two rotational transitions of CH{sub 3}OH (J{sub k} = 3{sub k} -> 2{sub k} and 2{sub k} -> 1{sub k}), and in the C{sup 34}S(J = 3 -> 2) line. In addition, single spectra at the peak position were taken in the CO(J = 1 -> 0), {sup 13}CO(J = 1 -> 0), and C{sup 18}O(J = 1 -> 0) lines. We find that the luminous star-forming regions are associated with molecular gas and dust structures with radii of typically 0.5 pc, masses of {approx}5 x 10{sup 3} M{sub sun}, column densities of {approx}5 x 10{sup 23} cm{sup -2}, molecular hydrogen densities of typically {approx}2 x 10{sup 5} cm{sup -3}, and dust temperatures of {approx}40 K. The 1.2 mm dust continuum observations further indicate that the cores are centrally condensed, having radial density profiles with power-law indices in the range 1.9-2.3. We find that under these conditions dynamical friction by the gas plays an important role in the migration of high-mass stars toward the central core region, providing an explanation for the observed stellar mass segregation within the cores. The CS profiles show two distinct emission components: a bright component, with line widths of typically 5 km s{sup -1} (FWHM), and a weaker and wider velocity component, which typically extends up to +-13 km s{sup -1} from the ambient cloud velocity. The SiO profiles also show emission from both components, but the intensity of the pedestal feature relative to that of the bright component is stronger than for CS. The narrow SiO component is likely to trace warm ambient gas close to the recently formed massive stars, whereas the high velocity emission indicates mass outflows produced by either the expansion of the H II regions, stellar winds, and/or collimated outflows. We find that the abundances of CS, CH{sub 3}OH, and SiO, relative to H{sub 2}, in the warm ambient gas of the massive cores are typically 4 x 10{sup -8}, 6 x 10{sup -9}, and 5 x 10{sup -11}, respectively.

Defective RNA polymerase II in the G1 specific temperature sensitive hamster cell mutant TsAF8.  


TsAF8 is a temperature-sensitive (TS) mutant of BHK21 cells that arrests at nonpermissive temperatures in the mid-G1 phase of the cell cycle. TsAmaR-1 is a TS for growth mutant of CHO cells with a Ts- and alpha-amanitin-resistant (AmaR) RNA polymerase II activity. Hybrid TsAmaR-1 x TsAF8 cell lines were constructed at permissive temperatures. Such hybrid cells did not grow at nonpermissive temperatures; the two TS mutations did not complement. Two different AmaR derivatives of TsAF8 were isolated. Each contained only AmaR polymerase II activity, indicating that this RNA polymerase II gene locus in TsAF8 is functionally hemizygous, as would be expected for a locus in which the recessive TsAF8 mutation had occurred. One of these AmaR isolates of TsAF8 had at. Two different AmaR derivatives of TsAF8 were isolated. Each contained only AmaR polymerase II activity, indicating that this RNA polymerase II gene locus in TsAF8 is functionally hemizygous, as would be expected for a locus in which the recessive TsAF8 mutation had occurred.

Forecasting ARIMA models for atmospheric vineyard pathogens in Galicia and Northern Portugal: Botrytis cinerea spores.  


Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other in Amares (Portugal), from 2005-2007. A volumetric trap, model Lanzoni VPPS-2000, was used for the aerobiological study. Phenological observations were conducted on 20 vines of three grape varieties in Cenlle (Treixadura, Godello and Loureira) and in Amares (Trajadura, Loureiro and Pedern), by using the BBCH scale. The highest total spore concentrations during the grapevine cycle were recorded in 2007 in both locations (Cenlle:16,145 spores; Amares:1,858 spores), and the lowest, in 2005 in Cenlle (1,700 spores) and in Amares (800 spores) in 2006. In Cenlle, the best adjusted model was an ARIMA (0,2,2), including the relative humidity four days earlier, while in Amares there was an ARIMA (1,2,3), considering the relative humidity three days earlier and rainfall two days earlier. The t-test showed no significant difference between observed and predicted data by the model. PMID:22742797

DNA-Mediated Transfer of an RNA Polymerase II Gene: Reversion of the Temperature-Sensitive Hamster Cell Cycle Mutant TsAF8 by Mammalian DNA  

PubMed Central

Treatment of the TsAF8 temperature-sensitive (TS) mutant of Syrian hamster BHK-21 cells, with calcium phosphate precipitates of genomic TS+ DNAs from a variety of mammalian cell lines permitted the selection of TS+ colonies at 40C. TS+ transformation events were distinguished from spontaneous TS+ reversions in experiments in which ?-amanitin-sensitive (AmaS) TS+ DNA was used to transform an AmaR derivative of TsAF8 cells and AmaR TS+ DNA was used to transform AmaS TsAF8 cells. In each case it was possible to demonstrate the unselected acquisition of the appropriate AmaS or AmaR phenotype with the selected TS+ allele. Each of these TS+ transformed cell lines when grown at 40C contained an RNA polymerase II activity with a sensitivity to inhibition by ?-amanitin characteristic of the particular DNA used to transform the TS cells, whereas at 34C the same cells contained a mixture of AmaR and AmaS polymerase II activities. Together, these data provide convincing evidence that the RNA polymerase II gene determining sensitivity to inhibition by ?-amanitin can be transferred to TsAF8 cells and that the TS defect in TsAF8 is a polymerase II mutation.

Network analysis provides deep insight into real complex systems. Revealing the link between topological and functional role of network elements can be crucial to understand the mechanisms underlying the system. Here we propose a Cytoscape plugin (GIANT) to perform network clustering and characterize nodes at the light of a modified Guimer-Amaral cartography. This approach results into a vivid picture of the a topological/functional relationship at both local and global level. The plugin has been already approved and uploaded on the Cytoscape APP store.

Sublattice parallel replica dynamics  

NASA Astrophysics Data System (ADS)

Exascale computing presents a challenge for the scientific community as new algorithms must be developed to take full advantage of the new computing paradigm. Atomistic simulation methods that offer full fidelity to the underlying potential, i.e., molecular dynamics (MD) and parallel replica dynamics, fail to use the whole machine speedup, leaving a region in time and sample size space that is unattainable with current algorithms. In this paper, we present an extension of the parallel replica dynamics algorithm [A. F. Voter, Phys. Rev. B 57, R13985 (1998), 10.1103/PhysRevB.57.R13985] by combining it with the synchronous sublattice approach of Shim and Amar [Y. Shim and J. G. Amar, Phys. Rev. B 71, 125432 (2005), 10.1103/PhysRevB.71.125432], thereby exploiting event locality to improve the algorithm scalability. This algorithm is based on a domain decomposition in which events happen independently in different regions in the sample. We develop an analytical expression for the speedup given by this sublattice parallel replica dynamics algorithm and compare it with parallel MD and traditional parallel replica dynamics. We demonstrate how this algorithm, which introduces a slight additional approximation of event locality, enables the study of physical systems unreachable with traditional methodologies and promises to better utilize the resources of current high performance and future exascale computers.

Geology and metallogeny of the Ar Rayn terrane, eastern Arabian shield: Evolution of a Neoproterozoic continental-margin arc during assembly of Gondwana within the East African orogen  

USGS Publications Warehouse

The Neoproterozoic Ar Rayn terrane is exposed along the eastern margin of the Arabian shield. The terrane is bounded on the west by the Ad Dawadimi terrane across the Al Amar fault zone (AAF), and is nonconformably overlain on the east by Phanerozoic sedimentary rocks. The terrane is composed of a magmatic arc complex and syn- to post-orogenic intrusions. The layered rocks of the arc, the Al Amar group (>689 Ma to ???625 Ma), consist of tholeiitic to calc-alkaline basaltic to rhyolitic volcanic and volcaniclastic rocks with subordinate tuffaceous sedimentary rocks and carbonates, and are divided into an eastern and western sequence. Plutonic rocks of the terrane form three distinct lithogeochemical groups: (1) low-Al trondhjemite-tonalite-granodiorite (TTG) of arc affinity (632-616 Ma) in the western part of the terrane, (2) high-Al TTG/adakite of arc affinity (689-617 Ma) in the central and eastern part of the terrane, and (3) syn- to post-orogenic alkali granite (607-583 Ma). West-dipping subduction along a trench east of the terrane is inferred from high-Al TTG/adakite emplaced east of low-Al TTG. The Ar Rayn terrane contains significant resources in epithermal Au-Ag-Zn-Cu-barite, enigmatic stratiform volcanic-hosted Khnaiguiyah-type Zn-Cu-Fe-Mn, and orogenic Au vein deposits, and the potential for significant resources in Fe-oxide Cu-Au (IOCG), and porphyry Cu deposits. Khnaiguiyah-type deposits formed before or during early deformation of the Al Amar group eastern sequence. Epithermal and porphyry deposits formed proximal to volcanic centers in Al Amar group western sequence. IOCG deposits are largely structurally controlled and hosted by group-1 intrusions and Al Amar group volcanic rocks in the western part of the terrane. Orogenic gold veins are largely associated with north-striking faults, particularly in and near the AAF, and are presumably related to amalgamation of the Ar Rayn and Ad Dawadimi terranes. Geologic, structural, and metallogenic characteristics of the Ar Rayn terrane are analogous to the Andean continental margin of Chile, with opposite subduction polarity. The Ar Rayn terrane represents a continental margin arc that lay above a west-dipping subduction zone along a continental block represented by the Afif composite terrane. The concentration of epithermal, porphyry Cu and IOCG mineral systems, of central arc affiliation, along the AAF suggests that the AAF is not an ophiolitic suture zone, but originated as a major intra-arc fault that localized magmatism and mineralization. West-directed oblique subduction and ultimate collision with a land mass from the east (East Gondwana?) resulted in major transcurrent displacement along the AAF, bringing the eastern part of the arc terrane to its present exposed position, juxtaposed across the AAF against a back-arc basin assemblage represented by the Abt schist of the Ad Dawadimi terrane. Our findings indicate that arc formation and accretionary processes in the Arabian shield were still ongoing into the latest Neoproterozoic (Ediacaran), to about 620-600 Ma, and lead us to conclude that evolution of the Ar Rayn terrane (arc formation, accretion, syn- to postorogenic plutonism) defines a final stage of assembly of the Gondwana supercontinent along the northeastern margin of the East African orogen. ?? 2007 Elsevier B.V.

Numerical solution of the Kardar-Parisi-Zhang equation with a long-range spatially correlated noise  

NASA Astrophysics Data System (ADS)

The Kardar-Parisi-Zhang (KPZ) equation for stochastic surface growth is numerically integrated in the presence of a long-range spatially correlated noise and the scaling behavior of the growing surfaces is investigated. A robust methodology for simulating the colored noise directly from uniform random variates is used with the discretized KPZ equation. The sample functions are expressed in terms of harmonic functions and the powerful fast Fourier transform is used. The growth exponents ? and ? are calculated and the results are compared with the predictions by Medina et al. [Phys. Rev. A 39, 3053 (1989)], Zhang [Phys. Rev. B 42, 4897 (1990)], and with the numerical results of Amar et al. [Phys. Rev. A 43, R4548 (1991)] and Peng et al. [Phys. Rev. A 44, R2239 (1991)]. The agreement of the present results with the theoretical prediction by Medina et al. shows that the current method of colored noise simulation is uniquely effective.

Implementing online natural gradient learning: problems and solutions.  


The online natural gradient learning is an efficient algorithm to resolve the slow learning speed and poor performance of the standard gradient descent method. However, there are several problems to implement this algorithm. In this paper, we proposed a new algorithm to solve these problems and then compared the new algorithm with other known algorithms for online learning, including Almeida-Langlois-Amaral-Plakhov algorithm (ALAP), Vario-eta, local adaptive learning rate and learning with momentum etc., using sample data sets from Proben1 and normalized handwritten digits, automatically scanned from envelopes by the U.S. Postal Services. The strong and weak points of these algorithms were analyzed and tested empirically. We found out that using the online training error as the criterion to determine whether the learning rate should be changed or not is not appropriate and our new algorithm has better performance than other existing online algorithms.

Further Geological Sampling Around the Rainbow Hydrothermal Site, Mid-Atlantic Ridge  

NASA Astrophysics Data System (ADS)

The Rainbow hydrothermal site, at 3614'N on the Mid-Atlantic Ridge, is one of the few known site hosted in ultramafic basement. The MOMAR DREAM cruise (July 2007, R/V Pourquoi Pas ?) combined biological and geological objectives to study the role of abundant iron in controlling geological, biological and hydrological active processes at all scales. Two Nautile dives and a dredging program were achieved to further constrain the lithology and geological structures on the seafloor at the scale of the massif that hosts Rainbow. This massif is an inside corner high of the non-transform offset between the AMAR and South AMAR second-order ridge segments, and presents the characteristic dome morphology of oceanic core complexes. The abundant sediment cover of the massif precludes continuous geological mapping and completely successful dredging. However, our limited sampling is consistent with the lithological variability encountered in other oceanic core complexes along the Mid-Atlantic Ridge. The Rainbow serpentinite basement was continuously observed to a distance of about 1 km to the south of the hydrothermal site, with serpentinites sampled along N-S trending, fault planes steeply dipping to the West. Serpentinites were also found on the northwestern, northern, and northeastern flanks of the massif. Approximately 800 m the North of the hydrothermal site, the most prominent outcrop, cut by a family of subvertical, ~ E-W faults, is at least partly made of olivine- orthopyroxene bearing gabbro. Basalts and fresh basaltic glass were also recovered in talus and sediments on the Southwest and Northeast flanks of the massif.

Fungal spores from Pleosporales in the atmosphere of urban and rural locations in Portugal.  


Fungal spores are a significant fraction of the atmospheric bioparticles (bioaerosols) and many species are capable of inducing the production of specific immunoglobulin E (IgE), aggravating the clinical symptoms of allergic respiratory diseases in sensitized individuals. The aim of this work was to evaluate the distribution of potentially allergenic Pleosporales spores in two locations with different urbanization indexes, characterizing its seasonal pattern. The seasonal distribution of several spore types belonging to the Pleosporales (Alternaria, Drechslera, Epicoccum, Paraphaeosphaeria, Pithomyces, Pleospora and Stemphylium) in Amares (rural area) and Porto (urban area) was continually studied from January 2005 to December of 2007, using Hirst-type volumetric spore traps. Alternaria was the most abundant fungal spore type found in the atmosphere of Amares and Porto. This fungal type, together with Drechslera, Epicoccum, Pithomyces and Stemphylium, was mainly present during summer. Nevertheless, Leptosphaeria, Pleospora and Venturia spores were detected during winter and spring, while Paraphaeosphaeria spores were also observed during summer and autumn. These different seasonal patterns were responsible for the expansion of the exposure period for the Alt a 1 allergen. The concentration of the studied spore types was higher in the rural area than in the urban one, with exception for Pleospora and Drechslera. According to the correlations with meteorological factors, the selected fungal spores can be divided into two groups: (i) Alternaria, Drechslera, Epicoccum, Pithomyces and Stemphylium presented positive correlations with temperature and negative correlations with relative humidity and rainfall; (ii) Leptosphaeria, Paraphaeosphaeria, Pleospora and Venturia presented a contrary behavior. Usually, the occurrence of the Alt a 1 allergen has been associated with the presence of airborne Alternaria spores; the present work follows the seasonal distribution of other fungal spore species known to contain this molecule. The widespread occurrence of Alt a 1 plays an important role in the incidence and aggravation of allergic disorders. PMID:21491687

Vent fluid chemistry of the Rainbow hydrothermal system (36N, MAR): Phase equilibria and in situ pH controls on subseafloor alteration processes  

NASA Astrophysics Data System (ADS)

The Rainbow hydrothermal field is located at 3613.8'N-3354.15'W at 2300 m depth on the western flank of a non-volcanic ridge between the South AMAR and AMAR segments of the Mid-Atlantic Ridge. The hydrothermal field consists of 10-15 active chimneys that emit high-temperature (365 C) fluid. In July 2008, vent fluids were sampled during cruise KNOX18RR, providing a rich dataset that extends in time information on subseafloor chemical and physical processes controlling vent fluid chemistry at Rainbow. Data suggest that the Mg concentration of the hydrothermal end-member is not zero, but rather 1.5-2 mmol/kg. This surprising result may be caused by a combination of factors including moderately low dissolved silica, low pH, and elevated chloride of the hydrothermal fluid. Combining end-member Mg data with analogous data for dissolved Fe, Si, Al, Ca, and H 2, permits calculation of mineral saturation states for minerals thought appropriate for ultramafic-hosted hydrothermal systems at temperatures and pressures in keeping with constraints imposed by field observations. These data indicate that chlorite solid solution, talc, and magnetite achieve saturation in Rainbow vent fluid at a similar pH (T,P) (400 C, 500 bar) of approximately 4.95, while higher pH values are indicated for serpentine, suggesting that serpentine may not coexist with the former assemblage at depth at Rainbow. The high Fe/Mg ratio of the Rainbow vent fluid notwithstanding, the mole fraction of clinochlore and chamosite components of chlorite solid solution at depth are predicted to be 0.78 and 0.22, respectively. In situ pH measurements made at Rainbow vents are in good agreement with pH (T,P) values estimated from mineral solubility calculations, when the in situ pH data are adjusted for temperature and pressure. Calculations further indicate that pH (T,P) and dissolved H 2 are extremely sensitive to changes in dissolved silica owing to constraints imposed by chlorite solid solution-fluid equilibria. Indeed, the predicted correlation between dissolved silica and H 2 defines a trend that is in good agreement with vent fluid data from Rainbow and other high-temperature ultramafic-hosted hydrothermal systems. We speculate that the moderate concentrations of dissolved silica in vent fluids from these systems result from hydrothermal alteration of plagioclase and olivine in the form of subsurface gabbroic intrusions, which, in turn are variably replaced by chlorite + magnetite + talc tremolite, with important implications for pH lowering, dissolved sulfide concentrations, and metal mobility.

Geological mapping of the Rainbow Massif, Mid-Atlantic Ridge, 3614'N  

NASA Astrophysics Data System (ADS)

The Rainbow hydrothermal field at 3614'N on the Mid-Atlantic Ridge is one of the few known sites hosted in ultramafic basement. The Rainbow Massif is located along the non-transform offset between the AMAR and South AMAR second-order ridge segments, and presents the characteristic dome morphology of oceanic core complexes, although no corrugated surface has been observed so far. One of the objectives of Cruises MOMAR DREAM (July 2007, R/V Pourquoi Pas ?; Aug-Sept 2008, R/V Atalante) was to study the petrological and structural context of the hydrothermal system at the scale of the Rainbow Massif. Our geological sampling complements previous ones achieved during Cruises FLORES (1997) and IRIS (2001), and consisted in dredge hauls, and submersible dives by manned submersible Nautile and ROV Victor. The tectonics of the Rainbow Massif is dominated by a N-S trending fault pattern on the western flank of the massif, and a series of SW-NW ridges on its northeastern side. The active hydrothermal site is located in the area were these two systems crosscut. The most abundant recovered rock type is peridotite (harzburgite and dunite) that presents a variety of serpentinization styles and intensity, and a variety of deformation styles (commonly undeformed, sometimes displaying ductile or brittle foliations). Serpentinites are frequently oxidized. Some peridotite samples have melt impregnation textures. Massive chromitite was recovered in one dredge haul. Variously evolved gabbroic rocks were collected as discrete samples or as centimeter to decimeter-thick dikes in peridotites. Basalts and fresh basaltic glass were also sampled in talus and sediments on the southwestern and northeastern flanks of the massif. Our sampling is consistent with the lithological variability encountered in oceanic core complexes along the Mid-Atlantic Ridge and Southwest Indian Ridge. The stockwork of the hydrothermal system has been sampled on the western side of the present-day hydrothermal field, along N-S trending normal fault scarps, and within the talus underneath. It is made of massive sulfides, strongly altered serpentinites, and breccias containing elements of iron sulfide/oxide impregnated serpentinites. * K. Bukas, V. Cueff Gauchard, L. Durand, F.

[Poliomyelitis in literature, cinema and television].  


INTRODUCTION. Poliomyelitis is an infectious disease whose initial symptoms are fever, fatigue, headaches, vomiting, a stiff neck and pains in the limbs. In many cases, the sequelae are irreversible paralysis and may result in death if there is bulbar or respiratory compromise. A set of symptoms, called post-polio syndrome, which appears years after the acute infection, are also described. AIM. To analyse the way poliomyelitis has been dealt with in literature, cinema and television. DEVELOPMENT. Film and television writers and directors have shown an interest in poliomyelitis and have portrayed it in a correct and realistic manner, both in fiction and in biographies or documentary-type works. Nemesis, Silver wattle, Leave her to heaven or The fall are some examples of literary works on the subject. Cinema has also portrayed polio all the way back to silent movies, with titles such as The woman in his house, The Silver Streak, Sister Kenny or The sessions. This disease and its sequelae have also been portrayed on television in series such as Hospital Central, Grey's anatomy, House M.D. or Amar en tiempos revueltos, and in TV films like El asunto, Eleanor and Franklin or Warm Springs. CONCLUSIONS. Poliomyelitis has been portrayed in literature, cinema and television in a realistic manner, showing its symptoms, sequelae, and the personal, familial and social impact of this disease.

The effects of meteorological factors on airborne fungal spore concentration in two areas differing in urbanisation level  

NASA Astrophysics Data System (ADS)

Although fungal spores are an ever-present component of the atmosphere throughout the year, their concentration oscillates widely. This work aims to establish correlations between fungal spore concentrations in Porto and Amares and meteorological data. The seasonal distribution of fungal spores was studied continuously (2005-2007) using volumetric spore traps. To determine the effect of meteorological factors (temperature, relative humidity and rainfall) on spore concentration, the Spearman rank correlation test was used. In both locations, the most abundant fungal spores were Cladosporium, Agaricus, Agrocybe, Alternaria and Aspergillus/Penicillium, the highest concentrations being found during summer and autumn. In the present study, with the exception of Coprinus and Pleospora, spore concentrations were higher in the rural area than in the urban location. Among the selected spore types, spring-autumn spores ( Coprinus, Didymella, Leptosphaeria and Pleospora) exhibited negative correlations with temperature and positive correlations both with relative humidity and rainfall level. On the contrary, late spring-early summer (Smuts) and summer spores ( Alternaria, Cladosporium, Epicoccum, Ganoderma, Stemphylium and Ustilago) exhibited positive correlations with temperature and negative correlations both with relative humidity and rainfall level. Rust, a frequent spore type during summer, had a positive correlation with temperature. Aspergillus/Penicillium, showed no correlation with the meteorological factors analysed. This knowledge can be useful for agriculture, allowing more efficient and reliable application of pesticides, and for human health, by improving the diagnosis and treatment of respiratory allergic disease.

Updating the Lamellar Hypothesis of Hippocampal Organization  

PubMed Central

Andersen et al. (1971) proposed that excitatory activity in the entorhinal cortex propagates topographically to the dentate gyrus, and on through a trisynaptic circuit lying within transverse hippocampal slices or lamellae. In this way, a relatively simple structure might mediate complex functions in a manner analogous to the way independent piano keys can produce a nearly infinite variety of unique outputs. The lamellar hypothesis derives primary support from the lamellar distribution of dentate granule cell axons (the mossy fibers), which innervate dentate hilar neurons and area CA3 pyramidal cells and interneurons within the confines of a thin transverse hippocampal segment. Following the initial formulation of the lamellar hypothesis, anatomical studies revealed that unlike granule cells, hilar mossy cells, CA3 pyramidal cells, and Layer II entorhinal cells all form axonal projections that are more divergent along the longitudinal axis than the clearly lamellar mossy fiber pathway. The existence of pathways with translamellar distribution patterns has been interpreted, incorrectly in our view, as justifying outright rejection of the lamellar hypothesis (Amaral and Witter, 1989). We suggest that the functional implications of longitudinally projecting axons depend not on whether they exist, but on what they do. The observation that focal granule cell layer discharges normally inhibit, rather than excite, distant granule cells suggests that longitudinal axons in the dentate gyrus may mediate lateral inhibition and define lamellar function, rather than undermine it. In this review, we attempt a reconsideration of the evidence that most directly impacts the physiological concept of hippocampal lamellar organization. PMID:23233836

Sublattice parallel replica dynamics.  


Exascale computing presents a challenge for the scientific community as new algorithms must be developed to take full advantage of the new computing paradigm. Atomistic simulation methods that offer full fidelity to the underlying potential, i.e., molecular dynamics (MD) and parallel replica dynamics, fail to use the whole machine speedup, leaving a region in time and sample size space that is unattainable with current algorithms. In this paper, we present an extension of the parallel replica dynamics algorithm [A. F. Voter, Phys. Rev. B 57, R13985 (1998)] by combining it with the synchronous sublattice approach of Shim and Amar [ and , Phys. Rev. B 71, 125432 (2005)], thereby exploiting event locality to improve the algorithm scalability. This algorithm is based on a domain decomposition in which events happen independently in different regions in the sample. We develop an analytical expression for the speedup given by this sublattice parallel replica dynamics algorithm and compare it with parallel MD and traditional parallel replica dynamics. We demonstrate how this algorithm, which introduces a slight additional approximation of event locality, enables the study of physical systems unreachable with traditional methodologies and promises to better utilize the resources of current high performance and future exascale computers.

Tertiary structure stability of the hairpin ribozyme in its natural and minimal forms: different energetic contributions from a ribose zipper motif.  


The hairpin catalytic motif in tobacco ringspot virus satellite RNA consists of two helix-loop-helix elements on two adjacent arms of a four-way helical junction. The bases essential for catalytic activity are located in the loops that are brought into proximity by a conformational change as a prerequisite for catalysis. The two loops interact via a ribose zipper motif involving the 2'-hydroxyls of A10, G11, A24, and C25 [Rupert, P. B., and Ferre d'Amare, A. R. (2001) Nature 401, 780-786]. To quantify the energetic importance of the ribose zipper hydrogen bonds, we have incorporated deoxy modifications at these four positions and determined the resulting destabilization of the docked conformer by means of time-resolved fluorescence resonance energy transfer. In a minimal form of the ribozyme, in which the loops are placed on the arms of a two-way helical junction, all modifications lead to a significant loss in tertiary structure stability and altered Mg2+ binding. Surprisingly, no significant destabilization was seen with the natural four-way junction ribozyme, suggesting that hydrogen bonding interactions involving the 2'-hydroxyls do not contribute to the stability of the docked conformer. These results suggest that the energetic contributions of ribose zipper hydrogen bonds are highly context dependent and differ significantly for the minimal and natural forms of the ribozyme.

3-D structure of the Galaxy from star-counts  

NASA Astrophysics Data System (ADS)

In the framework of a large project aimed to derive the Galactic structure from star-counts and kinematic information we present preliminary results concerning 6 fields in the direction of the Carina arm and one field in the bulge. Assuming a logarithmic spiral structure, we derive a pitch angle of 12.73o+/- 0.2o in the case of a four-armed spiral and a pitch angle of 6.53o+/-0.20 using a two-armed spiral. We cannot distinguish between a four- and a two- armed structure. However, the scale height of the Carina arm is found to be 0.05-0.1 kpc, definitely smaller than the value of 0.30 kpc suggested by Taylor & Cordes (1993) as a mean value for the spiral arms. This is in agreement with the dynamical model of the Galaxy by Amaral & Lepine (1997) where even if four arms are present, only two are dominant. The analysis of the bulge field suggests an age spread from 12 to 9 Gyr and a flat IMF.

Late Cryogenian-Ediacaran history of the Arabian-Nubian Shield: A review of depositional, plutonic, structural, and tectonic events in the closing stages of the northern East African Orogen  

NASA Astrophysics Data System (ADS)

During the late Cryogenian-Ediacaran (650-542 Ma), the Arabian-Nubian Shield (ANS) underwent final assembly and accretion to the Saharan Metacraton concurrent with the assembly of eastern and western Gondwana. At the end of the Precambrian it lay at one end of the East African Orogen, with its northern margin (present coordinates) forming a low-relief stable shelf facing an open ocean; to the south the ANS transitioned into the Mozambique Belt. The geologic history of the ANS during this period provides insight into the closing developmental stages of one of the world's largest accretionary orogens. Following a 680-640 Ma orogenic event reflecting amalgamation of a core grouping of island-arc terranes (the proto-Arabian-Nubian Shield; pANS), the region underwent extensive exhumation, erosion, and subsidence. Depositional basins formed in the northern and eastern pANS, with those in the east below sea level and connected to an ocean. Periodic basin closure and formation of new basins in other parts of the ANS followed. Many basins were filled by terrestrial, molasse-type sediments interfingering with subordinate to predominant amounts of volcanic rocks. Magmatism was extensive throughout the period, initially characterized by tonalite-trondhjemite-granodiorite (TTG) and granite (monzogranite, syenogranite), but also characterized, from 610 Ma on, by increasing amounts of alkali-feldspar granite and alkali granite. The plutons are largely undeformed, except where cut by brittle-ductile shear zones. The magma sources of the late Cryogenian-Ediacaran granitoids were dominated by juvenile crust and(or) depleted mantle and magmas mostly originated in anorogenic, post-collisional, commonly extensional, settings. They were derived by melting and fractionation of anhydrous high-grade metamorphosed lower crust, mafic- to intermediate calc-alkaline crust, and(or) subduction-modified mantle wedges associated with slab break-off or delamination. By 630 Ma, the region was affected by oblique (transpressional) convergence of continental blocks that formed eastern and western Gondwanathe pANS was approaching the Saharan Metacraton; north-trending shear and shortening zones developed in the southern ANS; and northwest-trending strike-slip shear zones of the Najd fault system dominated farther north. In the northwestern ANS, convergence and Najd transpression buckled the crust causing structural highs with domes of gneissic infracrust overlain by supracrust composed of ophiolitic and volcanosedimentary assemblages dating from the Tonian-middle Cryogenian period of island-arc activity. The supracrust was extensively translated to the northwest above a high-strain zone. Extension and tectonic escape augmented exhumation of the gneissic infracrust particularly between 620-580 Ma. In the northeastern ANS, linear belts of gneiss formed from reworked older intrusive bodies or syntectonic intrusions that were emplaced along Najd faults. By 620 Ma a marine basin on the eastern margin of the pANS (present coordinates) was beginning to close. A thick sedimentary assemblage (Abt formation) in this basin underwent metamorphism and folding, and subduction-related magmatism and volcanism farther into this basin (Al Amar arc; >690-615 Ma) was coming to an end. Amalgamation of the Abt formation, Al Amar arc, and the pANS occurred between 620 and 605 Ma, and terminal collision between the pANS and the Saharan Metacraton was complete by 580 Ma. At this time, the ANS was fully assembled. Granite magmatism continued until 565-560 Ma and orogeny ceased by 550 Ma. During these terminal events, the region underwent strong chemical weathering and became a vast low-relief surface on which Lower Paleozoic sandstone was eventually deposited.

Pesticide exposure and cancer among rural workers from Bariri, Sao Paulo State, Brazil.  


This article reports an environmental health study on risk identification. It discusses risk factors linked to rural work and pesticide contact in a restricted geographic area and shows the necessity of improving rural workers' health in the central part of Sao Paulo State. The municipality of Bariri, which is the case studied in this research, typifies this agriculturally based region. The study focuses on environmental problems engendered by modern agriculture that may have human-health repercussions such as cancer, as indicated by hard statistical association on an extended cause-effect time scale. For specific cases, the research used a database containing records of Amaral Carvalho Hospital, located in the city of Jau and a highly respected regional reference unit for over 85 years as one of the best in the Brazilian public health system for treating cancer. Statistics for age and gender were analyzed; relative risk was calculated for a group of cases registered from 2000 to 2002, as well as for a randomly selected control group from the same hospital. A map indicating the residences of cases (68) and non-cases (60) was made by geoprocessing techniques. For the period of time and the group studied, the authors concluded that the cancers of the skin and digestive system were the most prevalent. Bariri presented 24 cases representing all cancer types for each group of 10,000 citizens. The study indicated an almost two times higher probability of cancer development among rural workers, with a calculated relative risk between those exposed (agriculture workers) and the non-exposed (other occupations) of 1.6. No patterns of geographical distribution of cancer in that time period were recorded among rural workers of Bariri. However, the higher number of positive occurrences in the southwestern outskirts of the city indicated an area that must be prioritized in distributing environmental health information and conducting preventive education campaigns.

Isolation and characterization of 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole-resistant mutants of the Chinese hamster ovary cell line.  

PubMed Central

Mutants resistant to the RNA synthesis inhibitor 5,6-dichloro-1-beta-D-ribofurano-sylbenzimidazole (DRB) have been isolated in the Chinese hamster ovary cell line CHO-K1. Three independently isolated mutants, DRB6 DRB10, and DRB13, were 3-, 5-, and 3.5-fold, respectively, more resistant to DRB than the parental cell line WTCHO. The DRB-resistant mutations were expressed codominantly in somatic cell hybrids of DRB-resistant and DRB-sensitive cell lines. In vivo treatment of CHO-K1 cells with DRB resulted in specific inhibition of endogenous RNA polymerase II activity in cell lysates. Whereas DRB inhibited RNA polymerase II activity in WTCHO cells by a maximum of 60% at concentrations as low as 60 microM, 300 microM DRB was required to inhibit 60% of the RNA polymerase II activity in DRB10 cells. However, the inhibition of the DRB-sensitive RNA polymerase II activity in DRB10 was biphasic. About half (53 to 56%) of this activity was inhibited by 90 microM DRB and thus showed a DRB sensitivity similar to the wild-type RNA polymerase II activity; the remaining DRB-sensitive RNA polymerase II activity was maximally inhibited by 300 microM DRB. These results indicated that there were two copies of the drbR locus (drb+ and drbR-10) in DRB10 and confirmed that the drbR-10 mutation was expressed codominantly. Somatic cell hybrids of DRB-resistant and alpha-amanitin-resistant cell lines grew in medium containing both DRB and alpha-amanitin, demonstrating that the drbR and amaR mutations were not in the same gene. Thus, the drbR mutations may define an additional component of the RNA polymerase II transcriptional complex in mammalian cells. Images PMID:6180307

The DRB-resistant mutations were expressed codominantly in somatic cell hybrids of DRB-resistant and DRB-sensitive cell lines. In vivo treatment of CHO-K1 cells with DRB resulted in specific inhibition of endogenous RNA polymerase II activity in cell lysates. Whereas DRB inhibited RNA polymerase II activity in WTCHO cells by a maximum of 60% at concentrations as low as 60 microM, 300 microM DRB was required to inhibit 60% of the RNA polymerase II activity in DRB10 cells. However, the inhibition of the DRB-sensitive RNA polymerase II activity in DRB10 was biphasic. About half (53 to 56%) of this activity was inhibited by 90 microM DRB and thus showed a DRB sensitivity similar to the wild-type RNA polymerase II activity; the remaining DRB-sensitive RNA polymerase II activity was maximally inhibited by 300 microM DRB. These results indicated that there were two copies of the drbR locus (drb+ and drbR-10) in DRB10 and confirmed that the drbR-10 mutation was expressed codominantly. Somatic cell hybrids of DRB-resistant and alpha-amanitin-resistant cell lines grew in medium containing both DRB and alpha-amanitin, demonstrating that the drbR and amaR mutations were not in the same gene. Thus, the drbR mutations may define an additional component of the RNA polymerase II transcriptional complex in mammalian cells. PMID:6180307

Considerations on Terrestrial Iron Depositing Analogs to Earliest Mars  

NASA Technical Reports Server (NTRS)

Iron oxide and hydroxide minerals, including hematite, can mineralize and preservemicrofossils and physical biomarkers (Allen at al., 2004). Preserved remnants of phototrophic microorganisms are recognized as biosignatures of past life on Earth (Schopf, 2006). To date, two types of surface iron depositing environments have been studied as analogs to possible habitable environments on earliest Mars: the highly acidified Rio Tinto River (Iberian Belt, Spain) [Gomez Ortis et al., 2007], and the nearneutral iron depositing Chocolate Pots Hot Spring (Yellowstone National Park, US) [Parenteau at al., 2005]. While phototrophs in the Rio Tinto are only represented by eukaryotic algae (Amaral Zettler et all., 2002), Chocolate Pots is mainly populated with cyanobacteria (Pierson et all., 2000; Brown et all., 2007). Which of these environments is the closer analog to a potentially habitable early Mars? Paleobiological data, combined with recent "tree of life" interpretations, suggest that phototrophic eukaryotes evolved not earlier than 2.5 - 2.8 b.y. after Earth s accretion (4.6 b.y.), while cyanobacteria and /or their iron-tolerant predecessors evolved between 1 - 1.5 b.y. after accretion (Brown et al., 2007). Lindsay and Brasier (2002) postulated that microbial life on Mars surface could have lasted no more than 1-1.5 b.y. after Mars accretion (also 4.6 b.y.). Recent multispectral mapping of Mars suggests that near-neutral wet environments prevailed at approximately this time (Bibring, et al., 2006). Thus, near-neutral iron depositing hot springs such as Chocolate Pots Hot Spring seem to be the more likely habitable analogs for earliest Mars.

Microstructural finite strain analysis and 40Ar/39Ar evidence for the origin of the Mizil gneiss dome, eastern Arabian Shield, Saudi Arabia  

NASA Astrophysics Data System (ADS)

The Mizil antiform is a gneiss-cored culmination situated near the northern end of the Ar Rayn island arc terrane, which is the easternmost exposed tectonic unit of the Arabian Shield. This domal structure has a mantle of metamorphosed volcanosedimentary rocks belonging to the Al-Amar Group, and an igneous interior made up of foliated granodiorite-tonalite with adakitic affinity. The gneissic core has a SHRIMP U-Pb zircon age of 689 10 Ma making it the oldest rock unit in the Ar Rayn terrane. An adakite diapir, formed by the melting of the subducted crust of a young marginal basin, and rising through the volcanosedimentary succession of the Ar Rayn island arc is thought to have caused the observed doming. Relatively uniform strain throughout the dome combined with strong vertical shortening and the roughly radial pattern of stretching lineation is consistent with diapirism; the absence of strain localization rules out detachment faulting as a causative mechanism. Amphibolites from the metamorphic envelope have an 40Ar/39Ar age of 615 2 Ma; the age gap between core and cover is thought to reflect the resetting of metamorphic ages during the final suturing event, a phenomenon that is often observed throughout the eastern shield. Aeromagnetic anomalies beneath the Phanerozoic sedimentary cover indicate the presence of a collage of accreted terranes east of the Ar Rayn terrane that were probably amalgamated onto the Arabian margin during the latest stages of the closure of the Mozambique ocean; culminant orogeny is believed to have taken place between 620 and 600 Ma as these terrane collided with a major continental mass to the east referred to here as the eastern Arabian block (EAB). The Mizil gneiss dome is therefore considered to have formed in a convergent contractional setting rather than being the outcome of extensional post-orogenic collapse.

Distribution of oceanic and continental leads in the Arabian-Nubian Shield  

USGS Publications Warehouse

New common lead data for feldspar, whole-rock, and galena samples from the Arabian-Nubian Shield, together with data from previous work, can be divided into two main groups. Group I leads have oceanic (mantle) characteristics, whereas group II leads have incorporated a continental-crustal component of at least early Proterozoic age. The group I leads are found in rocks from the Red Sea Hills of Egypt and the western and southern parts of the Arabian Shield. Group II leads are found in rocks from the northeastern and eastern parts of the Arabian Shield, as well as from the southeastern Shield near Najran. They are also found in rocks to the south in Yemen, to the east in Oman, and to the west at Aswan, Egypt. This distribution of data suggests that the Arabian-Nubian Shield has an oceanic core flanked by rocks that have developed, at least in part, from older continental material. Two mechanisms are suggested by which this older lead component could have been incorporated into the late Proterozoic rocks, and each may have operated in different parts of the Shield. The older lead component either was derived directly from an underlying early Proterozoic basement or was incorporated from subducted pelagic sediments or sediments derived from an adjacent continent. New U-Pb zircon data indicate the presence of an early Proterozoic basement southeast of Jabal Dahul in the eastern Arabian Shield. These data, together with 2,000-Ma-old zircons from the Al Amar fault zone, verify the implication of the common lead data that at least a part of the eastern Arabian Shield has an older continental basement. Because continental margins are particularly favorable locations for development of ore deposits, these findings may have important economic implications, particularly for tin, tungsten, and molybdenum exploration. ?? 1983 Springer-Verlag.

Hard X-ray observations of the region from the galactic center to Centaurus  

NASA Technical Reports Server (NTRS)

A balloon flight from Parana, Argentina, was conducted to observe emissions from discrete or extended sources in the southern sky. The sources observed include GX 304-1, Nor X-2, GX 340+0, GX 354-5, a possibly composite source near the galactic center, and the nova-like source (2U1543-47) in the Lupus-Norma region which has been reported previously only in satellite observations. Data concerning the possibility of line emission near 0.5 MeV from different regions of the southern sky are also presented.

A Teacher's Perspective: What Is Culture?  

NSDL National Science Digital Library

In her chapter, "What Is Culture?," page 89, Norma Gonz�lez explains how the concept of culture has evolved historically and how it has affected education over time. As anthropologists continue to define culture in more dynamic ways, educators are encouraged to look beyond the rigid categories typically used to classify students--especially students from poor families and who speak a first language other than English--and see students as participants in many "cultural" communities. Ana Vaisenstein, a former first-grade teacher in a two-way bilingual school, shares her perspective.

Political dreams, practical boundaries: the case of the Nursing Minimum Data Set, 1983-1990.  


The initial development of the Nursing Minimum Data Set (NMDS) was analyzed based on archival material from Harriet Werley and Norma Lang, two nurses involved with the project, and American Nurses Association materials. The process of identifying information to be included in the NMDS was contentious. Individual nurses argued on behalf of particular data because of a strong belief in how nursing practice (through information collection) should be structured. Little attention was paid to existing practice conditions that would ultimately determine whether the NMDS would be used. PMID:21329148

A lead isotope study of mineralization in the Saudi Arabian Shield  

USGS Publications Warehouse

New lead isotope data are presented for some late Precambrian and early Paleozoic vein and massive sulfide deposits in the Arabian Shield. Using the Stacey Kramers (1975) model for lead isotope evolution, isochron model ages range between 720 m.y. and 420 m.y. Most of the massive sulfide deposits in the region formed before 680 m.y. ago, during evolution of the shield. Vein type mineralization of higher lead content occurred during the Pan African event about 550 m.y. ago and continued through the Najd period of extensive faulting in the shield that ended about 530 m.y. ago. Late post-tectonic metamorphism may have been responsible for vein deposits that have model ages less than 500 m.y. Alternatively some of these younger model ages may be too low due to the mineralizing fluids acquiring radiogenic lead from appreciably older local crustal rocks at the time of ore formation. The low207Pb/204Pb ratios found for the deposits in the main part of the shield and for those in north-eastern Egypt, indicate that the Arabian craton was formed in an oceanic crustal environment during the late Precambrian. Involvement of older, upper-crustal material in the formation of the ore deposits in this part of the shield is precluded by their low207Pb/204Pb and208Pb/204Pb characteristics. In the eastern part of the shield, east of longitude 44??20???E towards the Al Amar-Idsas fault region, lead data are quite different. They exhibit a linear207Pb/204Pb-206Pb/204Pb relationship together with distinctly higher208Pb/204Pb characteristics. These data imply the existence of lower crustal rocks of early Proterozoic age that apparently have underthrust the shield rocks from the east. If most of the samples we have analyzed from this easterly region were mineralized 530 m.y. ago, then the age of the older continental rocks is 2,100??300 m.y. (2??). The presence of upper crustal rocks, possibly also of early Proterozoic age, is indicated by galena data from Hailan in South Yemen and also from near Muscat in Oman. These data are the first to indicate such old continental material in these regions. ?? 1980 Springer-Verlag.

Different quantification algorithms may lead to different results: a comparison using proton MRS lipid signals.  


Proton magnetic resonance spectroscopy (MRS) is a sensitive method for investigating the biochemical compounds in a tissue. The interpretation of the data relies on the quantification algorithms applied to MR spectra. Each of these algorithms has certain underlying assumptions and may allow one to incorporate prior knowledge, which could influence the quality of the fit. The most commonly considered types of prior knowledge include the line-shape model (Lorentzian, Gaussian, Voigt), knowledge of the resonating frequencies, modeling of the baseline, constraints on the damping factors and phase, etc. In this article, we study whether the statistical outcome of a biological investigation can be influenced by the quantification method used. We chose to study lipid signals because of their emerging role in the investigation of metabolic disorders. Lipid spectra, in particular, are characterized by peaks that are in most cases not Lorentzian, because measurements are often performed in difficult body locations, e.g. in visceral fats close to peristaltic movements in humans or very small areas close to different tissues in animals. This leads to spectra with several peak distortions. Linear combination of Model spectra (LCModel), Advanced Method for Accurate Robust and Efficient Spectral fitting (AMARES), quantitation based on QUantum ESTimation (QUEST), Automated Quantification of Short Echo-time MRS (AQSES)-Lineshape and Integration were applied to simulated spectra, and area under the curve (AUC) values, which are proportional to the quantity of the resonating molecules in the tissue, were compared with true values. A comparison between techniques was also carried out on lipid signals from obese and lean Zucker rats, for which the polyunsaturation value expressed in white adipose tissue should be statistically different, as confirmed by high-resolution NMR measurements (considered the gold standard) on the same animals. LCModel, AQSES-Lineshape, QUEST and Integration gave the best results in at least one of the considered groups of simulated or in vivo lipid signals. These outcomes highlight the fact that quantification methods can influence the final result and its statistical significance. PMID:24493129

Two new species and new records of nasal mites of the genus Sternostoma (Acarina: Rhinonyssinae) from birds in Texas.  


Two new species and new host and locality records are established for nasal mites of the genus Sternostoma from birds in Texas. Sternostoma tracheacolum Lawrence is reported for the first time from Pipilo fuscus and Pyrrhuloxia sinuata, respectively. Additionally, a new host record for Sternostoma porteri Hyland from Centurus aurifrons and a new locality record for Sternostoma pirangae Pence from Piranga rubra are established. A redescription is provided for Sternostoma augei Amaral from Speotyto cunicularia. Sternostoma crotophagae sp. n. is described from Crotophaga sulcirostris. It differs from the other species of the genus by the heavily sclerotized margins of the anal plate and tiny cribrum, the two small rounded bifuractions of the movable digit of the chelicerae, abscence of dorsal opisthosomal setae (J, Z, and R series), and chaetotaxy of tarsi II, III, and IV which have only 3 ventral club-shaped setae in the distal row (al1, av2, and pl1 with pv1 apparently absent) and 2 club-shaped setae in the more proximal row (al2 and av3 with pv3 modified into a spinelike seta in the more proximal row and al2 and av3 with pv3 modified into a spinelike seta having an enlarged base and pl2 shorter and with a rounded tip). Sternostoma sayornis sp. n. is described from Sayornis nigricans. The new species is most similar to Sternostoma hedonophilum Fain but differs in the absence of enlarged punctate areas around the stigmata, 5 additional pairs of seta on dorsal opisthosoma (Z and R series), absence of gnathosomal and capitular setae, and slight differences in the leg chaetotaxy with al1 and pl1 on tarsi II, III, and IV very long and whip-like and slight differences in the solenidia on and adjacent to the sensorial area of tarsus I. The host-parasite relationships and affinities of the species of Sternostoma from the host family Tyrannidae are briefly discussed and Sternostoma callithrix Fain and Aitken is reduced as a synonym of Sternostoma longisetosa Hyland on the basis of their existing descriptions.

High Temperature Hydrothermal Components in the Sediment Cover of the Saldanha Hydrothermal Field  

NASA Astrophysics Data System (ADS)

The Saldanha hydrothermal field is located at a non-transform offset (NTO5), between the FAMOUS and AMAR segments on the Mid-Atlantic Ridge (N36 34'; W33 26'). This field was discovered in 1998 during the Saldanha cruise (FCT, Portugal and IFREMER, France) and was revisited in 2001 during the Seahma cruise (FCT, Portugal) and in 2004 during the CD167 cruise (NOC, UK and FCT, Portugal). It is a serpentinite-hosted hydrothermal field and in situ observations revealed that hydrothermal vents are scarce and disseminated along the ocean floor over an area of approximately 400m2. Weakly venting fluids discharge through centimeter-sized orifices. Maximum fluid temperatures of 9 C were measured with the Victor ROV in 2001. Surface sediments have been collected from the Saldanha hydrothermal field in 1998, 2001 and 2004 and differences concerning mineralogy and geochemistry were recorded between these sediments. Mineralogy, whole sediment geochemistry and isotope ((? 13C, ? 18O, Pb and Nd) data suggest geochemical variations in hydrothermal activity in this system. Hydrothermal activity is more strongly recorded in sediments collected in 2004, which are richer in sulfide mineralization and in hydrothermally- derived elements such as Cu, Zn, Fe, Co, Ni and S. In these sediments, rare earth elements (REE) patterns are characteristically derived from vent fluids, with enrichment in light REE and a pronounced positive Eu anomaly. The seawater-derived REE components in these sediments are low, as revealed by a small negative Ce anomaly. Lead isotopic ratios are typically less radiogenic in the youngest sediments when compared with the ones recorded in 1998 and 2001 sediments, demonstrating a negligible contribution of Pb from pelagic sediments. This is in agreement with neodymium isotope analyses indicating a smaller seawater contribution in the 2004 sediments. Oxygen isotope compositions (?18OSMOW=6,59-11,63) of hydrothermal calcites present throughout the 2004 sediment core imply much higher temperatures of mineral precipitation (up to 260 C ) than those measured directly at the vent orifices in 2001 (9 C).Hydrothermal minerals are precipitated subsurface, preserving minerals from oxidizing conditions. The high temperature of mineral precipitation suggested by our data requires a significant heat input to this system, raising the question of the heat source of this system and the role of serpentinization processes, as no magmatic heat source has yet been found.

Multistage late Cenozoic evolution of the Amargosa River drainage, southwestern Nevada and eastern California Society of America. All rights reserved  

USGS Publications Warehouse

Stratigraphic and geomorphic analyses reveal that the regional drainage basin of the modern Amargosa River formed via multistage linkage of formerly isolated basins in a diachronous series of integration events between late Miocene and latest Pleistocene-Holocene time. The 275-km-long Amargosa River system drains generally southward across a large (15,540 km 2) watershed in southwestern Nevada and eastern California to its terminus in central Death Valley. This drainage basin is divided into four major subbasins along the main channel and several minor subbasins on tributaries; these subbasins contain features, including central valley lowlands surrounded by highlands that form external divides or internal paleodivides, which suggest relict individual physiographic-hydrologic basins. From north to south, the main subbasins along the main channel are: (1) an upper headwaters subbasin, which is deeply incised into mostly Tertiary sediments and volcanic rocks; (2) an unincised low-gradient section within the Amargosa Desert; (3) a mostly incised section centered on Tecopa Valley and tributary drainages; and (4) a west- to northwest-oriented mostly aggrading lower section along the axis of southern Death Valley. Adjoining subbasins are hydro-logically linked by interconnecting narrows or canyon reaches that are variably incised into formerly continuous paleodivides. The most important linkages along the main channel include: (1) the Beatty narrows, which developed across a Tertiary bedrock paleodivide between the upper and Amargosa Desert subbasins during a latest Miocene-early Pliocene to middle Pleistocene interval (ca. 4-0.5 Ma); (2) the Eagle Mountain narrows, which cut into a mostly alluvial paleodivide between the Amar-gosa Desert and Tecopa subbasins in middle to late Pleistocene (ca. 150-100 ka) time; and (3) the Amargosa Canyon, which formed in late middle Pleistocene (ca. 200140 ka) time through a breached, actively uplifting paleodivide between the Tecopa and southern Death Valley subbasins. Collectively, the interconnecting reaches represent discrete integration events that incrementally produced the modern drainage basin starting near Beatty sometime after 4 Ma and ending in the Salt Creek tributary in the latest Pleistocene to Holocene (post-30 ka). Potential mechanisms for drainage integration across paleodivides include basin overtopping from sedimentary infilling above paleodivide elevations, paleolake spillover, groundwater sapping, and (or) headward erosion of dissecting channels in lower-altitude subbasins. These processes are complexly influenced by fluvial responses to factors such as climatic change, local base-level differences across divides, and (or) tectonic activity (the latter only recognized in Amargosa Canyon). ?? 2008 The Geological Society of America.

The Edge of the Young Galactic Disk  

NASA Astrophysics Data System (ADS)

In this work, we report and discuss the detection of two distant diffuse stellar groups in the third Galactic quadrant. They are composed of young stars, with spectral types ranging from late O to late B, and lie at galactocentric distances between 15 and 20 kpc. These groups are located in the area of two cataloged open clusters (VdB-Hagen 04 and Ruprecht 30), projected toward the Vela-Puppis constellations, and within the core of the Canis Major overdensity. Their reddening and distances have been estimated by analyzing their color-color and color-magnitude diagrams, derived from deep UBV photometry. The existence of young star aggregates at such extreme distances from the Galactic center challenges the commonly accepted scenario in which the Galactic disk has a sharp cutoff at about 14 kpc from the Galactic center and indicates that it extends to much greater distances (as also supported by the recent detection of CO molecular complexes well beyond this distance). While the groups we find in the area of Ruprecht 30 are compatible with the Orion and Norma-Cygnus spiral arms, respectively, the distant group we identify in the region of VdB-Hagen 04 lies in the external regions of the Norma-Cygnus arm, at a galactocentric distance (~20 kpc) where no young stars have been detected so far in the optical.

Galaxy Clusters in the Swift/BAT era II: 10 more Clusters detected above 15 keV  

SciTech Connect

We report on the discovery of 10 additional galaxy clusters detected in the ongoing Swift/BAT all-sky survey. Among the newly BAT-discovered clusters there are: Bullet, Abell 85, Norma, and PKS 0745-19. Norma is the only cluster, among those presented here, which is resolved by BAT. For all the clusters we perform a detailed spectral analysis using XMM-Newton and Swift/BAT data to investigate the presence of a hard (non-thermal) X-ray excess. We find that in most cases the clusters emission in the 0.3-200 keV band can be explained by a multi-temperature thermal model confirming our previous results. For two clusters (Bullet and Abell 3667) we find evidence for the presence of a hard X-ray excess. In the case of the Bullet cluster, our analysis confirms the presence of a non-thermal, power-law like, component with a 20-100 keV flux of 3.4 x 10{sup -12} erg cm{sup -2} s{sup -1} as detected in previous studies. For Abell 3667 the excess emission can be successfully modeled as a hot component (kT = {approx}13 keV). We thus conclude that the hard X-ray emission from galaxy clusters (except the Bullet) has most likely thermal origin.

Extragalactic large-scale structures behind the southern Milky Way. III. Redshifts obtained at the SAAO in the Great Attractor region  

NASA Astrophysics Data System (ADS)

In the third of a series of papers on large-scale structures behind the southern Milky Way, we report here on redshifts obtained at the South African Astronomical Observatory (SAAO) in the Great Attractor region (318deg <~ l <~ 340deg , |b| <= 10deg , Woudt 1998). This region encompasses the peak in the reconstructed mass density field, associated with the Great Attractor (Kolatt et al. 1995, Dekel et al. 1998) and covers the crossing of the Supergalactic Plane with the Galactic Plane. Our deep optical galaxy search in the Zone of Avoidance (ZOA) in this region (Woudt 1998) has resulted in the detection of 4423 galaxies with observed diameters larger than 0.2 arcmin. We have obtained reliable redshifts for 309 galaxies of the 4423 galaxies with the ``Unit'' spectrograph (first with a Reticon, then with a CCD detector) at the 1.9-m telescope of the SAAO. An additional 13 tentative redshifts are presented. Before our survey, 127 galaxies had a previously recorded redshift (NED and SRC96). Given a small overlap with the literature (44 galaxies), we present here redshifts for 265 galaxies that had no previous recorded velocity. In addition, we present central velocity dispersion (sigma_o ) measurements for 34 galaxies in ACO 3627. It is known that the Great Attractor (GA) region is overdense in galaxies at a redshift-distance of v ~ 5000 {km s-1 } (Fairall 1988, Dressler 1991, Visvanathan & Yamada 1996, di Nella et al. 1997). We realise here, however, that the Great Attractor region is dominated by ACO 3627 (hereafter referred to as the Norma cluster), a highly obscured, nearby and massive cluster of galaxies close to the plane of the Milky Way (l, b, v) = (325.3deg , -7.2deg , 4844 {km s-1 }) (Kraan-Korteweg et al. 1996, Woudt 1998). Previous redshift surveys in the GA region have failed to gauge the significance of the Norma cluster, primarily due to the diminishing effects of the Galactic foreground extinction on the partially obscured galaxies. In the absence of the obscuring effects of the Milky Way, the Norma cluster would have appeared as prominent as the well-known Coma cluster, but nearer in redshift-space. This cluster most likely marks the bottom of the potential well of the Great Attractor (Woudt 1998). All the tables are only available in electronic form at the CDS via anonymous ftp to ( or via

Star counts and IRAS sources in southern dark clouds.  

NASA Astrophysics Data System (ADS)

Star counts were performed towards 9 southern dark clouds situated in the cloud complexes of Vela, Carina, Chamaeleon, Musca, Circinus and Norma, and in the Southern Coalsack, using the ESO(B), SRC-J and ESO(R) plates. Maps of the distribution of visual extinction are presented for each cloud, and the masses contained within different extinction contour levels estimated. The distribution and color indices of the IRAS point sources found in projection to the clouds are investigated. The color indices are used to point out sources which are probable young stellar objects embedded in the clouds; the nature of these objects is discussed; in some cases they are used as distance indicators.

Decline and present status of breeding peregrine falcons in Oregon  

USGS Publications Warehouse

In 1979, only one Peregrine Falcon pair (they fledged two young) and a single adult male were located. A population decline east of the Cascades began in rhe 1930's, probably resulting from a climatic change (drought); however, a statewide decline began in the late 1940's, accelerated in the 1950's, and by the 1960's few pairs remained. The statewide decline closely paralleled the pattern of DDT use. Furthermore, DDE was found in membranes of peregrine eggs from nearby California as early as 1948. Moreover, an unhatched Peregrine Falcon egg found at the Oregon eyrie in 1979 contained 19 ppm DDE and lesser amounts of other contaminants. The eggshell was 19% thinner than normaL The future of the nearly extirpated Peregrine Falcon in Oregon remains uncertain in spite of improved water and habitat conditions in eastern Oregon. Reintroduction of captive-bred birds seems to be the last hope.

An EPIC view of absorbed HMXBs in the Scutum Arm  

NASA Astrophysics Data System (ADS)

Observations are proposed for 5 new unclassified gamma-ray sources in the Scutum Arm. Each source will be targeted by EPIC PN and MOS cameras for 25 ks providing us with: a refined position that will facilitate optical/IR identification; spectral characteristics including the slope of the power law in X-rays and the photoelectric absorption; and timing characteristics in the case of Galactic XRBs. The targets lie within 5degs of the plane of the Milky Way, towards the tangent to the Scutum Arm, and are expected to be Galactic in origin. The main objective is to elucidate the nature of these sources. An additional benefit is that we will have a more complete sample of high-energy emitters in the Scutum Arm to compare with absorbed HMXBs in the Norma Arm.

The impact of land use on biological activity of agriculture soils. An State-of-the-Art  

NASA Astrophysics Data System (ADS)

Biological activity is a crucial soil property affecting soil sustainability and crop production. The unsuitable land management can lead to a loss in soil fertility and a reduction in the abundance and diversity of soil microorganisms. This can be as a consequence of high erosion rates due to the mismanagement of farmers (Cerd et al., 2009a). However ecological practices and some organic amendments can promote the activities of soil microbial communities, and increase its biodiversity (Garca-Orenes et al., 2010; 2013). The impact of land use in microbiological properties of agriculture soil are presented and discussed in this review. Biological activity is quantified by microbial soil communities and soil enzyme activities to interpret the effects of soil management practices (Morugn-Coronado et al., 2013). The aim of biological activity tests is to give a reliable description of the state of agricultural soils under the effect of different land uses. Numerous methods have been used to determine the impact of land uses on microbiological properties. The current used methods for detecting microbial diversity are based on molecular techniques centered on the 16S and 18S rRNA encoding sequences such as CLPP: community-level physiological profiles; T-RFLP: terminal restriction fragment length polymorphism; DGGE: denaturing gradient gel electrophoresis; OFRG: oligonucleotide fingerprinting of rRNA genes, ARISA: Automated Ribosomal intergenic spacer analysis, SSCP: single-strand conformation polymorphism. And techniques based on the cellular composition of the microbes such as PLFA: phospholipid fatty acid analysis. Other methods are based on the activity of microbes, for example, Cmic: microbial biomass carbon; SIR: substrate induced respiration; BSR: Basal soil respiration; qCO2 metabolic quotient; enzymatic activities (Urease, -glucosidase and phosphatase) (Deng, 2012). Agricultural land management can contribute to increased rates of erosion due to desiccation, mechanical destruction, soil compaction, reduce pore volume, and disruption of access to food resources (Cerd et al., 2009b). Furthermore, it can lead to a loss in soil fertility and reduction in the abundance and diversity of soil microorganism (Caravaca et al., 2002). Nevertheless, some organic fertilizers, such as manure, waste water and sewage sludge, promote the activities of soil microbial communities (Morugn-Coronado et al., 2011; Balota et al., 2013; Macci et al., 2013). On the other hand, land use influences soil microbial processes by changing the quantity and quality of plant residues entering the soil and their spatial distribution, thorough changes in nutrients and inputs (Garca-Orenes et al., 2009; 2012). The abuse of pesticides can drastically modify the function and structure of microbial communities, altering the terrestrial ecosystems, which has important implication for soil quality (Pampulha et al., 2006). Soil quality is important for the sustainable development of terrestrial ecosystem (Paz-Ferreiro & Fu, 2013; Vasconcellos et al., 2013). This paper will review the State-of-the-Art of the scientific knowledge on the impact of land use on the biological activity in agriculture soils Acknowledgements The research projects GL2008-02879/BTE, LEDDRA 243857 and RECARE supported this research.

Star formation in Sandqvist 187 and 188  

NASA Astrophysics Data System (ADS)

We present 1.2 mm continuum data of the filamentary dark cloud Sandqvist 187/188 - also known as the Norma cloud - taken with SIMBA (SEST Imaging Bolometer Array). The data are complemented by measurements from the 2MASS, MSX and IRAS surveys. The extended 1.2 mm emission traces the optical dark cloud down to a visual extinction of AV = 3.7 mag. We derive a mean column density of N(H_2) = 1.4 1022 cm-2, equivalent to a visual extinction of AV = 7.6 mag and a total mass of the cloud of 340 M_?. We also find six compact millimetre sources, labelled MMS 1 to 6, five of which coincide with known stellar objects. MMS 6, however, only has a very weak MSX counterpart at 14.56 ?m and an absorption feature at 8.28 ?m consistent with a visual extinction of AV > 145 mag. Dust temperatures, luminosities and gas masses for all compact millimetre sources are given. In an effort to further constrain the uncertain distance to Sandqvist 187/188, we analyse its stellar content based on 2MASS colours and find an improved lower limit of 440 50 pc.

Using binary classification to prioritize and curate articles for the Comparative Toxicogenomics Database  

PubMed Central

We report on the original integration of an automatic text categorization pipeline, so-called ToxiCat (Toxicogenomic Categorizer), that we developed to perform biomedical documents classification and prioritization in order to speed up the curation of the Comparative Toxicogenomics Database (CTD). The task can be basically described as a binary classification task, where a scoring function is used to rank a selected set of articles. Then components of a question-answering system are used to extract CTD-specific annotations from the ranked list of articles. The ranking function is generated using a Support Vector Machine, which combines three main modules: an information retrieval engine for MEDLINE (EAGLi), a gene normalization service (NormaGene) developed for a previous BioCreative campaign and finally, a set of answering components and entity recognizer for diseases and chemicals. The main components of the pipeline are publicly available both as web application and web services. The specific integration performed for the BioCreative competition is available via a web user interface at PMID:23221176

GPU accelerated Hybrid Tree Algorithm for Collision-less N-body Simulations  

E-print Network

We propose a hybrid tree algorithm for reducing calculation and communication cost of collision-less N-body simulations. The concept of our algorithm is that we split interaction force into two parts: hard-force from neighbor particles and soft-force from distant particles, and applying different time integration for the forces. For hard-force calculation, we can efficiently reduce the calculation and communication cost of the parallel tree code because we only need data of neighbor particles for this part. We implement the algorithm on GPU clusters to accelerate force calculation for both hard and soft force. As the result of implementing the algorithm on GPU clusters, we were able to reduce the communication cost and the total execution time to 40% and 80% of that of a normal tree algorithm, respectively. In addition, the reduction factor relative the normal tree algorithm is smaller for large number of processes, and we expect that the execution time can be ultimately reduced down to about 70% of the norma...

RXTE observations of strongly absorbed sources IGR J16318-4848 and IGR J16358-4726  

E-print Network

Results of analysis of RXTE observations of strongly absorbed X-ray sources IGR J16318-4848 and IGR J16358-4726 are presented. Careful subtraction of Galactic ridge emission contribution to the observed spectra of RXTE/PCA allowed us to obtain the spectra of the sources in 3-25 keV energy band. Spectra of the sources cold be well described by a power law with photoabsorption. It is shown that the value of absorption column in the case of RXTE observation of IGR J16318-4848 performed on March 14.1, 2003 is somewhat higher that that obtained by XMM observatory on Feb 10.7 2003. This could imply that the source has variable absorption, presumably connected with an orbital phase of the binary system. It is noted, that all three X-ray sources, discovered by INTEGRAL observatory in the sky region of (l,b)~(336,0) (IGR J16318-4848, IGR J16320-4751 and IGR J16358-4726) have large intrinsic photoabsorption and could be high mass X-ray binaries. This hypothesis has indirect support from the fact that their are located close to the Norma spiral arm tangent, i.e. in the region of enhanced concentrations of young massive stars. If they are reside within this spiral arm some rough estimation of the sources distance could be made -- D~6-8 kpc.

Photothermal technique in cell microscopy studies  

NASA Astrophysics Data System (ADS)

Photothermal (PT) method is applied for a cell imaging and quantitative studies. The techniques for cell monitoring, imaging and cell viability test are developed. The method and experimental set up for optical and PT-image acquisition and analysis is described. Dual- pulsed laser set up combined with phase contrast illumination of a sample provides visualization of temperature field or absorption structure of a sample with spatial resolution 0.5 micrometers . The experimental optics, hardware and software are designed using the modular principle, so the whole set up can be adjusted for various experiments: PT-response monitoring or photothermal spectroscopy studies. Sensitivity of PT-method provides the imaging of the structural elements of live (non-stained) white blood cells. The results of experiments with normal and subnormal blood cells (red blood cells, lymphocytes, neutrophyles and lymphoblasts) are reported. Obtained PT-images are different from optical analogs and deliver additional information about cell structure. The quantitative analysis of images was used for cell population comparative diagnostic. The viability test for red blood cell differentiation is described. During the study of neutrophyles in norma and sarcoidosis disease the differences in PT-images of cells were found.

The Supernova Remnant CTA 1  

NASA Technical Reports Server (NTRS)

The supernova remnants G327.1-1.1 and G327.4+0.4 (Kes 27) are located 1.5 deg apart in the constellation Norma. In 1980, Einstein IPC observations discovered that both were irregular filled-center X-ray sources with possible point sources superposed. This paper describes new ROSAT position sensitive proportional counter (PSPC) observations which both map the diffuse structure and clearly show several unresolved sources in each field. Both remnants have bright emitting regions inside the limb which might indicate the presence of high energy electrons accelerated by a pulsar. The interior region is more prominent in G327.1-1.1 than in Kes 27. The spectra are relatively strongly absorbed, as expected from distant remnants close to the galactic plane. Comparison of the X-ray and radio maps of each remnant allows us to attribute some emission to a shell and some to the interior. With this information, a blast-wave model is used to derive approximate ages and energy release. Indications are that the Kes 27 supernova deposited approximately 10(exp 51) ergs in the surrounding medium. The G327.1-1.1 event probably deposited a factor of 3-10 less.

Exploring Cultural Heritage Resources in a 3d Collaborative Environment  

NASA Astrophysics Data System (ADS)

Cultural heritage is a complex and diverse concept, which brings together a wide domain of information. Resources linked to a cultural heritage site may consist of physical artefacts, books, works of art, pictures, historical maps, aerial photographs, archaeological surveys and 3D models. Moreover, all these resources are listed and described by a set of a variety of metadata specifications that allow their online search and consultation on the most basic characteristics of them. Some examples include Norma ISO 19115, Dublin Core, AAT, CDWA, CCO, DACS, MARC, MoReq, MODS, MuseumDat, TGN, SPECTRUM, VRA Core and Z39.50. Gateways are in place to fit in these metadata standards into those used in a SDI (ISO 19115 or INSPIRE), but substantial work still remains to be done for the complete incorporation of cultural heritage information. Therefore, the aim of this paper is to demonstrate how the complexity of cultural heritage resources can be dealt with by a visual exploration of their metadata within a 3D collaborative environment. The 3D collaborative environments are promising tools that represent the new frontier of our capacity of learning, understanding, communicating and transmitting culture.

[The federal government discourse during the political decentralization process and the obstacles to implement the Brazilian Public Health Care System].  


A discourse analysis carried out on basic operating standard Norma Operacional Bsica do Sistema Unico de Sade (NOB-SUS 01/96) of the Brazilian public health care system aiming at locating signs that could allow to identify lines of thought which have influenced health care policies prioritized by the federal administration. The author points out a peculiarity in the kind of discourse employed by the ministry directive: its structure is based on isolated aspects of legislation and on ideas advocated by other discourse communities, articulated with redefined legal principles - an effort towards authorizing the official reasoning in favor of the relevance in keeping the decentralization process under the control of the federal administration. The analysis concludes that an infra-legal standard can neither grant state and federal administrations a hierarchical superiority (mediation function) over municipal administrations, nor can it transfer the legal responsibilities pertaining to Health Councils over to inter-administration commissions (Comisses Intergestores) , thus making the former mere decision ratifiers. This study found that granting privileges not contemplated in the legislation to state and federal administrations surfaced again and more strongly so in 2001 in yet another operating standard.

Classification and prioritization of biomedical literature for the comparative toxicogenomics database.  


We present a new approach to perform biomedical documents classification and prioritization for the Comparative Toxicogenomics Database (CTD). This approach is motivated by needs such as literature curation, in particular applied to the human health environment domain. The unique integration of chemical, genes/proteins and disease data in the biomedical literature may advance the identification of exposure and disease biomarkers, mechanisms of chemical actions, and the complex aetiologies of chronic diseases. Our approach aims to assist biomedical researchers when searching for relevant articles for CTD. The task is functionally defined as a binary classification task, where selected articles must also be ranked by order of relevance. We design a SVM classifier, which combines three main feature sets: an information retrieval system (EAGLi), a biomedical named-entity recognizer (MeSH term extraction), a gene normalization (GN) service (NormaGene) and an ad-hoc keyword recognizer for diseases and chemicals. The evaluation of the gene identification module was done on BioCreativeIII test data. Disease normalization is achieved with 95% precision and 93% of recall. The evaluation of the classification was done on the corpus provided by BioCreative organizers in 2012. The approach showed promising performance on the test data. PMID:22874182

MUSE sneaks a peek at extreme ram-pressure stripping events. I. A kinematic study of the archetypal galaxy ESO137-001  

E-print Network

We present MUSE observations of ESO137-001, a spiral galaxy infalling towards the center of the massive Norma cluster at z~0.0162. During the high-velocity encounter of ESO137-001 with the intracluster medium, a dramatic ram-pressure stripping event gives rise to an extended gaseous tail, traced by our MUSE observations to >30 kpc from the galaxy center. By studying the H-alpha surface brightness and kinematics in tandem with the stellar velocity field, we conclude that ram pressure has completely removed the interstellar medium from the outer disk, while the primary tail is still fed by gas from the galaxy center. Gravitational interactions do not appear to be a primary mechanism for gas removal. The stripped gas retains the imprint of the disk rotational velocity to ~20 kpc downstream, offering evidence that ESO137-001 is fast moving along a radial orbit in the plane of the sky. Beyond ~20 kpc, a greater degree of turbulence is seen, with velocity dispersion up to >100 km/s. For a model-dependent infall vel...

NuSTAR Galactic Plane Survey Program  

NASA Astrophysics Data System (ADS)

The NuSTAR Galactic Plane Survey program consists of several deep surveys and dedicated pointing observations. The survey of a 2x0.8 degree field near Sgr A* should detect hundreds of the sources uncovered by Chandra and help identify their nature by spectroscopy and timing analysis. A similar survey of the Norma region will be performed for comparative population studies. An observation of the Limiting Window, which holds a possible new class of CVs, will yield information on their nature. With NuSTAR's superb hard X-ray sensitivity, these surveys will detect and map the low energy extension of the diffuse gamma-ray background observed by INTEGRAL. NuSTAR will observe Sgr A*, in coordination with Chandra and other observatories, to search for hard X-ray flaring, and provide an image of the central few tens of parsecs of the Galaxy with more than an order of magnitude better sensitivity than INTEGRAL. NuSTAR plans to observe the G2 molecular cloud's infall to Sgr A* in the spring of 2013. NuSTAR will spatially resolve the hard X-ray emission in the molecular cloud Sgr B2. In addition, the 2x0.8 degree field survey will observe other giant molecular clouds such as Sgr A, B1 and C to help us understand their X-ray emission possibly due to a giant flare from Sgr A* in the past.

Bacterial Synthesis and Purification of Normal and Mutant Forms of Human FGFR3 Transmembrane Segment.  


The fibroblast growth factor receptor 3 (FGFR3) is a protein belonging to the family of receptor tyrosine kinases. FGFR3 plays an important role in human skeletal development. Mutations in this protein, including Gly380Arg or Ala391Glu substitutions in the transmembrane (TM) region, can cause different disorders in bone development. The determination of the spatial structure of the FGFR3 TM domain in a normal protein and in a protein with single Gly380Arg and Ala391Glu mutations is essential in order to understand the mechanisms that control dimerization and signal transduction by receptor tyrosine kinases. The effective system of expression of eukaryotic genes in bacteria and the purification protocol for the production of milligram amounts of both normal TM fragments of FGFR3 and those with single pathogenic mutations Gly380Arg and Ala391Glu, as well as their(15)N- and [(15)N,(13)C]-isotope-labelled derivatives, were described. Each peptide was produced inEscherichia coliBL21(DE3)pLysS cells as a C-terminal extension of thioredoxin A. The purification protocol involved immobilized metal affinity chromatography and cation- and anion-exchange chromatography, as well as the fusion protein cleavage with the light subunit of human enterokinase. The efficiency of the incorporation of target peptides into DPC/SDS and DPC/DPG micelles was confirmed using NMR spectroscopy. The described methodology of production of the native FGFR3 TM domain in norma and with single Gly380Arg and Ala391Glu mutations enables one to study their spatial structure using high-resolution heteronuclear NMR spectroscopy.

From Large Scale Surveys of the Galaxy to High Resolution Observations with ALMA  

NASA Astrophysics Data System (ADS)

A CS(2-1) survey of OB star forming regions provides statistics of their distribution in the Galaxy. The complete scenario of massive star formation for one particular GMC, at a distance of 1.6 kpc, is revealed through 1.2 mm continuum observations for spatial scales from 1 pc to 50 pc. Using large scale CO and C18O maps from NANTEN at 2.5' resolution, we identified toward the peak of C18O one of the most luminous regions of high-mass star formation in the Galaxy, G331.5, toward the tangent of Norma spiral arm, at a distance of 7.5 kpc. Observations at 1.2 mm continuum emission with SIMBA at SEST reveal the presence of a cluster of six massive millimeter clumps, with high bolometric luminosity, making G331.5 one of the most densely populated GMC cores known so far. High density molecular tracers reveal the presence, in the center of the most massive clump, of a compact, highly massive and energetic molecular outflow, with a velocity width reaching 160 km s-1 (fwzp). Further interferometric continuum observations at 3.6 cm and 6 cm shows that this powerful outflow is associated with a compact radio continuum source, likely producing highly ionized stellar wind. ALMA observations were carried in band 7 to this unresolved molecular outflow. SiO and H13CO+ observations unveil a shell-like structure toward the ambient velocity of the source, evidence of an isotropic high speed wind. The derived crossing time for this source indicates that the molecular outflow in G331.5 is one of the youngest outflow found around an OB star.

MUSE sneaks a peek at extreme ram-pressure stripping events - I. A kinematic study of the archetypal galaxy ESO137-001  

NASA Astrophysics Data System (ADS)

We present Multi Unit Spectroscopic Explorer (MUSE) observations of ESO137-001, a spiral galaxy infalling towards the centre of the massive Norma cluster at z 0.0162. During the high-velocity encounter of ESO137-001 with the intracluster medium, a dramatic ram-pressure stripping event gives rise to an extended gaseous tail, traced by our MUSE observations to >30 kpc from the galaxy centre. By studying the H? surface brightness and kinematics in tandem with the stellar velocity field, we conclude that ram pressure has completely removed the interstellar medium from the outer disc, while the primary tail is still fed by gas from the inner regions. Gravitational interactions do not appear to be a primary mechanism for gas removal. The stripped gas retains the imprint of the disc rotational velocity to 20 kpc downstream, without a significant gradient along the tail, which suggests that ESO137-001 is fast moving along a radial orbit in the plane of the sky. Conversely, beyond 20 kpc, a greater degree of turbulence is seen, with velocity dispersion up to ?100 km s-1. For a model-dependent infall velocity of vinf 3000 km s-1, we conclude that the transition from laminar to turbulent flow in the tail occurs on time-scales ?6.5 Myr. Our work demonstrates the terrific potential of MUSE for detailed studies of how ram-pressure stripping operates on small scales, providing a deep understanding of how galaxies interact with the dense plasma of the cluster environment.

Optimal Spectral Regions For Laser Excited Fluorescence Diagnostics For Point Of Care Application  

NASA Astrophysics Data System (ADS)

The tissue fluorescence gives the response of light emitting molecule signature, and characterizes the cell composition and peculiarities of metabolism. Both are useful for the biomedical diagnostics, as reported in previous our and others works. The present work demonstrates the results of application of laser excited autofluorescence for diagnostics of pathology in genital tissues, and the feasibility for the bedside at "point of careoff lab" application. A portable device using the USB spectrophotometer, micro laser (355 nm Nd:YAG, 0,5 ns pulse, repetition rate 10 kHz, output power 15 mW), three channel optical fiber and computer with diagnostic program was designed and ready for clinical trial to be used for cytology and biopsy specimen on site diagnostics, and for the endoscopy/puncture procedures. The biopsy and cytology samples, as well as intervertebral disc specimen were evaluated by pathology experts and the fluorescence spectra were investigated in the fresh and preserved specimens. The spectra were recorded in the spectral range 350-900 nm. At the initial stage the Gaussian components of spectra were found and the Mann-Whitney test was used for the groups' differentiation and the spectral regions for optimal diagnostics purpose were found. Then a formal dividing of spectra in the components or the definite width bands, where the main difference of the different group spectra was observed, was used to compare these groups. The ROC analysis based diagnostic algorithms were created for medical prognosis. The positive prognostic values and negative prediction values were determined for cervical Liquid PAP smear supernatant sediment diagnosis of being Cervicitis and Norma versus CIN2+. In a case of intervertebral disc the analysis allows to get the additional information about the disc degeneration status. All these results demonstrated an efficiency of the proposed procedure and the designed device could be tested at the point-of-care site or for intervertebral disc operations.

Spectroscopy of southern Galactic disk planetary nebulae. Notes on chemical composition and emission-line stars  

NASA Astrophysics Data System (ADS)

Aims: We present low resolution spectroscopic observations for a sample of 53 planetary nebulae (PNe) located in the southern sky between Vela and Norma constellations and pertaining to the Galactic disk with expected Galactocentric distance range of 5 to 10 kpc. Methods: We derive nebular chemical composition and plasma parameters with the classical empirical method. For most of the observed objects, this has been done for the first time. We compare our results to published data for PNe of the Galactic bulge and PNe in the inner-disk region with expected typical Galactocentric distance of about 3 kpc. We use the spectra to search for emission-line central stars in the observed sample. Results: The distributions of the chemical abundances of the observed disk sample are generally indistinguishable from Galactic bulge and inner-disk PNe populations. The exceptions are possible differences in the He/H distribution, as compared to bulge PNe and Ne/Ar, as compared to the inner-disk PNe sample. The derived O/H ratios for the observed disk PNe fit to the concept of flattening of the chemical gradient in the inner parts of the Milky Way. Investigating the spectra, we found six new emission-line central stars comprising examples of all known types: WEL, VL, and [WR]. We confirm that these types represent three evolutionary unconnected forms of enhanced mass-loss in the central stars of PNe. We note on the problem of high ionisation PNe with nebular C IV emission that can mimic the presence of WEL central stars in 1D spectra. Based on observations made at the South African Astronomical Observatory.Appendices are available in electronic form at

Catalog of Observed Tangents to the Spiral Arms in the Milky Way Galaxy  

NASA Astrophysics Data System (ADS)

From the Sun's location in the Galactic disk, one can use different arm tracers (CO, H I, thermal or ionized or relativistic electrons, masers, cold and hot dust, etc.) to locate a tangent to each spiral arm in the disk of the Milky Way. We present a master catalog of the astronomically observed tangents to the Galaxy's spiral arms, using different arm tracers from the literature. Some arm tracers can have slightly divergent results from several papers, so a mean value is takensee the Appendix for CO, H II, and masers. The catalog of means currently consists of 63 mean tracer entries, spread over many arms (Carina, Crux-Centaurus, Norma, Perseus origin, near 3 kpc, Scutum, Sagittarius), stemming from 107 original arm tracer entries. Additionally, we updated and revised a previous statistical analysis of the angular offset and linear separation from the mid-arm for each different mean arm tracer. Given enough arm tracers, and summing and averaging over all four spiral arms, one could determine if arm tracers have separate and parallel lanes in the Milky Way. This statistical analysis allows a cross-cut of a Galactic spiral arm to be made, confirming a recent discovery of a linear separation between arm tracers. Here, from the mid-arm's CO to the inner edge's hot dust, the arm halfwidth is about 340 pc doubling would yield a full arm width of 680 pc. We briefly compare these observations with the predictions of many spiral arm theories, notably the density wave theory.

The Scientist as Sentinel (Invited)  

NASA Astrophysics Data System (ADS)

Scientists have been warning the world for some time about the risks of anthropogenic interference in the climate system. But we struggle with how, exactly, to express that warning. The norms of scientific behavior enjoin us from the communication strategies normally associated with warnings. If a scientist sounds excited or emotional, for example, it is often assumed that he has lost his capacity to assess data calmly and therefore his conclusions are suspect. If the scientist is a woman, the problem is that much worse. In a recently published article my colleagues and I have shown that scientists have systematically underestimated the threat of climate change (Brysse et al., 2012). We suggested that this occurs for normative reasons: The scientific values of rationality, dispassion, and self-restraint lead us to demand greater levels of evidence in support of surprising, dramatic, or alarming conclusions than in support of less alarming conclusions. We call this tendency 'erring on the side of least drama.' However, the problem is not only that we err on the side of least drama in our assessment of evidence, it's also that we speak without drama, even when our conclusions are dramatic. We speak without the emotional cadence that people expect to hear when the speaker is worried. Even when we are worried, we don't sound as if we are. In short, we are trying to act as sentinels, but we lack the register with which to do so. Until we find those registers, or partner with colleagues who are able to speak in the cadences that communicating dangers requires, our warnings about climate change will likely continue to go substantially unheeded.

Origins of the Highly Ionized Gas along the Line of Sight towards HD 116852  

E-print Network

We present Hubble Space Telescope Imaging Spectrograph (HST/STIS) and Far Ultraviolet Spectroscopic Explorer (FUSE) observations of high ion interstellar absorption along the sight line to HD 116852. At a distance of 4.8 kpc, HD 116852 is an O9 III star lying in the low Galactic halo, -1.3 kpc from the plane of the Galaxy in the direction l = 304.9, b = -16.1. The STIS E140H grating observations provide high-resolution (FWHM = 2.7 km/s) spectra of the resonance doublets of Si IV, C IV, and N V. These data are complemented by medium-resolution (FWHM = 20 km/s) FUSE spectra of O VI. We find evidence for three distinct types of highly ionized gas present in the data. First, two narrow absorption components are resolved in the Si IV and C IV profiles, at approximate LSR velocities of -36 and -10 km/s. These narrow components appear to be produced in gas associated with the Norma and Sagittarius spiral arms, at approximate z-distances of -1.0 and -0.5 kpc, respectively. Second, we detect an intermediate-width component in C IV and Si IV, at 17 km/s, which we propose could arise at the conductive interface at the boundary between a low column density neutral or weakly ionized cloud and the surrounding hot medium. Finally, a broad collisionally ionized component of gas responsible for producing the smooth N V and O VI profiles is observed; such absorption is also present to a lesser degree in the profiles of Si IV and C IV. The broad O VI absorption is observed at a velocity displaced from the broad C IV component by almost 20 km/s, an amount large enough to suggest that the two ions may not co-exist in the same physical location.

FOREWORD: V S Letokhov  

NASA Astrophysics Data System (ADS)

Comments on Atomic, Molecular and Optical Physics (CAMOP) endeavors periodically to devote an issue to the life and accomplishments of physicists who have made significant contributions to the fields represented in this journal. Vladilen Letokhov is certainly one of them. For a number of years he was also a CAMOP Correspondent. We are grateful to Professor Victor Balykin for having organized this CAMOP special section. It is particularly significant to one of us (HHS) to remember a person who has made seminal advances in so many areas which to this day are at the forefront of studies by a number of physicists. But over the years this acquaintance developed into friendship and gave the wife of one of us, Norma, and HHS the opportunity to host Tina and Vladik in their home, and get to know both a bit better. There was also the seminal International School on Laser Applications in Physics in Vilnius organized by Letokhov, and then a visit to Troitsk and his group at the Institute of Spectroscopy (and even the organization of a couple of piano recitals by one of our daughters, Marija, who accompanied her parents in the then USSR). Our interests crossed in a couple of fields: laser interactions with atoms and sensitive spectroscopy of radioactive atoms. Letokhov was a participant in the early organization of laser spectroscopy at CERN and was instrumental in providing copper vapour lasers to the isotope separator facility, ISOLDE. To this day laser ion sources are under the aegis of Valentin Fedoseyev who came to CERN from Troitsk. The interaction of lasers with atoms, in particular the process of slowing atoms, is discussed by Balykin. It was Christmas time when a card arrived from Oleg Tumanov of the Institute of Spectroscopy: it included a graph of temperature achieved by laser cooling as a function of calendar date. The results of Letokhov's group were the earliest (see figure 1), even though lower temperatures achieved subsequently by others extended our knowledge. To many, the lack of formal recognition was a bit puzzling, and this will have to await the usual number of decades before relevant discussions become publicSee, for example, Friedman R M 2001 The Politics of Excellence (New York: Henry Holt).. But, as can be attested by the most prolific, diverse and creative contributions presented in the bibliography, Letokhov's work will leave a long-lasting legacy. Progress in laser cooling Figure 1.

Physical Characteristics of G331.5-0.1: The Luminous Central Region of a Giant Molecular Cloud  

NASA Astrophysics Data System (ADS)

We report molecular line and dust continuum observations toward the high-mass star-forming region G331.5-0.1, one of the most luminous regions of massive star formation in the Milky Way, located at the tangent region of the Norma spiral arm, at a distance of 7.5 kpc. Molecular emission was mapped toward the G331.5-0.1 GMC in the CO(J = 1 ? 0) and C18O(J = 1 ? 0) lines with NANTEN, while its central region was mapped in CS(J = 2 ? 1 and J = 5 ? 4) with SEST, and in CS(J = 7 ? 6) and 13CO(J = 3 ? 2) with ASTE. Continuum emission mapped at 1.2 mm with SIMBA and at 0.87 mm with LABOCA reveal the presence of six compact and luminous dust clumps, making this source one of the most densely populated central regions of a GMC in the Galaxy. The dust clumps are associated with molecular gas and they have the following average properties: size of 1.6 pc, mass of 3.2 103 M ?, molecular hydrogen density of 3.7 104 cm-3, dust temperature of 32 K, and integrated luminosity of 5.7 105 L ?, consistent with values found toward other massive star-forming dust clumps. The CS and 13CO spectra show the presence of two velocity components: a high-velocity component at ~ - 89 km s-1, seen toward four of the clumps, and a low-velocity component at ~ - 101 km s-1 seen toward the other two clumps. Radio continuum emission is present toward four of the molecular clumps, with spectral index estimated for two of them of 0.8 0.2 and 1.2 0.2. A high-velocity molecular outflow is found at the center of the brightest clump, with a line width of 26 km s-1 (FWHM) in CS(J = 7 ? 6). Observations of SiO(J = 7 ? 6 and J = 8 ? 7), and SO(JK = 88 ? 77 and JK = 87 ? 76) lines provide estimates of the gas rotational temperature toward this outflow >120 K and >75 K, respectively.

Treatment with salicylic acid decreases the effect of cadmium on photosynthesis in maize plants.  


The present study investigated the possible mediatory role of salicylic acid (SA) in protecting photosynthesis from cadmium (Cd) toxicity. Seeds of maize (Zea mays L., hybrid Norma) were sterilized and divided into two groups. Half of the seeds were presoaked in 500 microM SA solution for only 6h, after which both groups were allowed to germinate for 3d and were then grown for 14d in Hoagland solution at 22/18 degrees C in a 16/8-h light/dark period and 120 micromolm(-2)s(-1) PAR. All seedlings (without H(2)O and SA controls) were transferred to Cd-containing solutions (10, 15, and 25 microM) and grown for 14d. The rate of CO(2) fixation and the activity of ribulose 1,5-bisphosphate carboxylase (RuBPC, EC and phosphoenolpyruvate carboxylase (PEPC, EC were measured. Changes in the levels of several important parameters associated with oxidative stress, namely H(2)O(2) and proline production, lipid peroxidation, electrolyte leakage, and the activities of antioxidative enzymes (superoxide dismutase (SOD, EC, ascorbate peroxidase (APX, EC, catalase (CAT, EC, and guaiacol peroxidase (POD, EC were measured. Exposure of the plants to Cd caused a gradual decrease in the shoot and root dry weight accumulation, with the effect being most pronounced at 25 microM Cd. Seed pretreatment with SA alleviated the negative effect of Cd on plant growth parameters. The same tendency was observed for the chlorophyll level. The rate of CO(2) fixation was lower in Cd-treated plants, and the inhibition was partially overcome in SA-pretreated plants. A drop in the activities of RuBPC and PEPC was observed for Cd-treated plants. Pretreatment with SA alleviated the inhibitory effect of Cd on enzyme activity. Proline production and the rates of lipid peroxidation and electrolyte leakage increased in Cd-treated plants, whereas the values of these parameters were much lower in SA-pretreated plants. Treatment of plants with Cd decreased APX activity, but more than doubled SOD activity. Pretreatment with SA caused an increase in both APX and SOD activity, but caused a strong reduction in CAT activity. The data suggest that SA may protect cells against oxidative damage and photosynthesis against Cd toxicity. PMID:17913285

Spirituality and Cultural Identification Among Latino and Non-Latino College Students  

PubMed Central

The purposes of this study were to examine (a) differences in spiritual perspectives and practices of Latino and non-Latino young adults and (b) the cultural relevance of the Latino Spiritual Perspective Scale (LSPS). Studies indicate that spiritual perspectives are embedded within cultural group norms and vary significantly across ethnic groups. A cross-sectional survey design was used with a convenience sample of 223 Latino and non-Latino university students in the Southwestern United States. The Spiritual Perspective Scale (SPS), the LSPS, the Orthogonal Cultural Identification Scale, and a demographic questionnaire were used. Latinos scored significantly higher than non-Latinos in both measures of spiritual perspectives. Self-reported behavioral measures, such as frequency of personal prayer, were also higher among the Latino group. Latino cultural identification was the only significant predictor of LSPS scores. Findings from this study indicate that spirituality among Latinos has meanings specific to the cultural group context. These findings have implications for nursing research involving the conceptualization and measurement of spirituality among multiethnic groups. Los propsitos de este estudio eran examinar: (a) diferencias en perspectivas espirituales y prcticas de jvenes Latinos y no Latinos; y (b) la relevancia cultural de la Escala de la Perspectiva Espiritual Latina. Estudios indican que perspectivas espirituales estn incrustadas entre normas culturales del grupo y varan considerablemente entre grupos tnicos. Un diseo transversal y de encuesta fue utilizado con una muestra de conveniencia de 233 estudiantes universitarios Latinos y no Latinos en el Suroeste de los Estados Unidos. La Escala de la Perspectiva Espiritual (EPE), la Escala de la Perspectiva Espiritual Latina (EPEL), la Escala Ortogonal de Identificacin Cultural, y un cuestionario demogrfico fueron utilizados. Los Latinos calificaron considerablemente ms alto que los no Latinos en ambas medidas de perspectivas espirituales. Medidas de comportamiento auto-reportadas, como la frecuencia de oracin, tambin estuvieron ms altas en el grupo Latino. La identificacin con la cultura Latina fue el nico vaticinador de las calificaciones de la EPEL. Los resultados de este estudio indican que la espiritualidad entre Latinos tiene significados especficos al contexto del grupo cultural. Estas conclusiones tienen implicaciones para las investigaciones de enfermera que involucran la conceptualizacin y medida de la espiritualidad entre grupos multitnicos. PMID:20165566

Hydrochemistry of waters from five cenotes and evaluation of their suitability for drinking-water supplies, northeastern Yucatan, Mexico  

NASA Astrophysics Data System (ADS)

Waters from five cenotes that are currently being used for aquatic recreational activities and that lie along the Cancun-Tulum touristic corridor, Mexico, were evaluated hydrochemically to determine whether the cenotes may be considered as potential drinking-water sources. Several parameters exceed the Mexican Drinking Water Standards (MDWS), but since they do not pose a significant health threat, four of the five cenotes may be used as drinking-water sources. The common contaminants in the Yucatan Peninsula, fecal coliforms and nitrate, are in most cases below the MDWS (0-460 MPN/100ml and 0.31-1.18mg/L, respectively). Although these four cenotes meet the MDWS, a careful groundwater management policy needs to be developed to avoid contamination (fecal and nitrates) and salt-water intrusion. Rsum Les eaux de cinq cnots, qui sont normalement utilises pour des activits de plein air, dans la rgion touristique de Cancun-Tulum (Mexique), ont t soumises analyses chimiques pour savoir si les cnots peuvent tre considrs comme des sources d'eau potable. Plusieurs paramtres dpassent les normes mexicaines en matire d'eau potable; mais comme ceux-ci ne posent pas de problme rel de sant, quatre des cinq cnots peuvent tre capts pour l'eau potable. Les contaminants habituels dans les eaux de la presqu'le du Yucatan, coliformes fcaux et concentrations leves en nitrate, sont la plupart du temps au-dessous des normes (respectivement 0 460 germes/100ml et 0,31 1,18mg/l). Bien que ces quatre cnots satisfassent aux normes, il est ncessaire de mettre en place des rgles prcises de l'utilisation de l'eau souterraine, afin d'viter la contamination par les germes fcaux et par les nitrates, ainsi que l'intrusion marine. Resumen Se analiz hidroqumica y bacteriolgicamente el agua de algunos cenotes localizados a lo largo del corredor turstico Cancun-Tulum, que actualmente se utilizan para diversas actividades recreativas, para determinar su potencial de uso como fuente de abastecimiento de agua potable. La mayor parte de los parmetros excedieron los criterios establecidos en la Norma Mexicana para Agua Potable (NMAP), sin embargo, como stas no representan una riesgo para la salud, el agua de cuatro de los cinco cenotes puede ser emplada como fuente de abastecimiento de agua potable. Los contaminantes comnes del agua subterrnea de la pennsula de Yucatn, coliformes fecales y nitratos, se encuentran en la mayora de los casos por debajo de la NMAP (0-460 NMP/ 100ml y 0.31-1.18mg/l, respectivamente). A pesar de que estos cuatro cenotes cumplen con la NMAP, es necesario desarrollar una poltica de manejo adecuada del agua subterrnea para evitar la contaminacin de este recurso (fecal y por nitratos), as como la intrusin de agua salina.

Project Seacleaner: from cooperation among ISMAR-CNR researchers, high school students and the Ligurian Cluster for Marine Technologies to an application for environmental monitoring and scientific research.  

NASA Astrophysics Data System (ADS)

Recently, the Institute for Marine Science of the Italian Research Council ISMAR-CNR has undertaken a series of actions to incorporate oceanography in education: among these, the project "SeaCleaner" that has been developed together with a local Secondary School (Istituto di Istruzione Superiore Capellini-Sauro) and the Ligurian Cluster for Marine Technologies (DLTM) [1]. Seven students, engaged within the national Programme "work-related learning"[2], have worked side-by-side with ISMAR-CNR researchers, investigating on the problem of debris accumulation on beaches, and understanding the damage that this issue causes to marine environments and ecosystems. This problem has recently become a challenging research subject for an increasing number of oceanographers and, in general, for environmental researchers coming from the Mediterranean areas [3, 4, 5], other European Seas [6] and Oceans [7, 8]. Data collected during repeated surveys (seasonally) in the same beach stretch, over several years, allow calculating debris accumulation rates and flow intensities. Application of current models gives additional information on debris dispersal and origin, but we shouldn't forget that, generally, relevance of acquired data is determined by the accuracy and standardization of the procedure. In this context, students have previously searched for literature sources and summarized the most important issues, among these: few data that are often collected during small ranges of time and usually a low number of available researchers for carrying out such a time-consuming survey in the field. In a initial part of the project, several trial surveys have been performed on different beaches in La Spezia province, in order to understand how to elaborate possible strategies to speed up and standardize the procedure. Developing an application for Android system (downloadable on any compatible mobile device such as smartphones, tablets, etc.) has been considered as a good solution since it is easy to spread and distribute among non-technical end-users. This app will help final users to carry out a standard monitoring procedure, in a quick way. All data (photographs, site characteristics, kind of debris, waypoints) will be properly captured and semi-automatically registered on a separate electronic spreadsheet. SeaCleaner app can be provided to environmental associations, marine parks, volunteers and its easy approach will allow us to obtain standardized and safe data, upcoming from an increasing number of points, which will be acquired in situ and then saved on a dedicated remote database. Citizen participation in scientific programs, already experienced in the field of astronomy [9] has been effective also in other scientific fields, both from the scientific and social point of view, since it brings people closer to science and fills the gap between who produces science and technology and who benefits from it ("citizen science") [10, 11]. SeaCleaner is ready to be used during the school year 2013/2014 to test its validity and usefulness. Further internships and collaborations between ISMAR and educational institutions, will allow us by the end of April 2014 to show the first dataset processed in this experimental phase. It is worth to highlight the active involvement of young people in this project and its effectiveness as a tool for raising awareness on environmental issues and orientating young people towards scientific careers. The project has been awarded in November 2013 as the best regional work-related learning project.

[Emtine and quinine, a therapy to rescue Bellini in 1835].  


At the moment when his operas got a European celebrity, Vincenzo Bellini born in 1801 rapidly died in September 1835 after a three weeks digestive illness, with mainly dysenteria. Young and healthy, this unexpected event questioned the authorities in Paris. The post mortem examination showed that the colonic mucosa was covered by numerous ulcers, and that a large abcess existed in the liver. All other parts of the body were absolutely sound. These results came out from the autopsy performed by Adolphe Dalmas (1799-1844), professor agrg at the Faculty of medicine of Paris, formerly member of the special committee in charge of fighting the cholera in 1831 and 1832, who studied its medical aspects during the epidemic attack in Russia, Poland, Germany and Great Britain. With a wide knowledge in the field of the intestinal pathology, his conclusions established that the death came from an inflammation of the bowel, excluding clearly any touch of cholera or poisoning. Nowadays, it is obvious that this dysenteria syndome associated to such anatomic disorders would belong to the chronic amebic disease. Probably contaminated in 1828, Bellini developed a severe episode in 1830, necessitating a long rest during several months, spent at Moltrasio along the side of the Lake of Como. At the time, he composed La Sonnambula and Norma. In 1833 after staying in London from April to August, he came to Paris preparing a new work I Puritani (The Puritains). At summer time, he usually suffered slight recurring episodes, that he treated by applying vesicatories. For frequent periods, he lived outside Paris in a villa standing along the Seine in Puteaux rented by his British friends the Levys. Early in September 1835, these symptoms came again and and suddenly worsened with pain, fever and loss of rest at night. Deserted and lonely as the Levys often left the villa, his critical condition exhibiting tremendous sufferings led to death on the 23rd of September. During the final days, he was not granted any relevant medical support, except the poor cares given by the Italian physician Montallegri, not authorised at that time to practice in France. As emetine and quinine since 1822 were both available as pure alcaloids, produced by the pharmacist Joseph Pelletier, it is assumed that Bellini might have recovered after an intensive treatment implementing these substances by oral, local and rectal routes (enemas and suppositories). At that time, apart from the academic teaching inherited from Broussais, the tropical practitioners currently used them in the treatment of dysenteria and tropical liver abcesses (Annesley, Segond and Dutroulau), as decocted ipeca roots and cinchona barks. Later on when the amebic disease has gained its proper nosography, the clinicians underlined the dangerous and unpredictable issues of the hyperacute hepatic syndromes, unexpected and occurring by apparently healthy individuals. By 1960, its treatment was still obtained by the emetine derivatives. PMID:12515278

PREFACE: The XI Mexican School on Particles and Fields  

NASA Astrophysics Data System (ADS)

The XI Mexican School on Particles and Fields took place on 2-13 August 2004, in the city of Xalapa, Veracruz, Mxico. The School continued with the tradition of promoting High Energy Physics among the younger generation in Mexico. Thus, it was aimed specifically at graduate students and postdocs. The School consisted of several courses delivered by international experts on subjects of current interest to the scientific community. The length of each course was of six to eight hours, English being the language of instruction. A novelty in this edition of the School was its total duration (two weeks as opposed to one), the number of hours assigned to one subject, and the addition of some experimental courses for the students to overcome their inhibitions of a direct encounter with the equipment and its usage. There were also a few overview talks delivered by local experts on the current status of some of the research fields actively pursued in Mexico. The XI-MSPF was organized by the Particles and Fields Division of the Mexican Physical Society. It was generously sponsored by several institutions: Universidad de Veracruz, Universidad Nacional Autnoma de Mxico, Universidad Michoacana de San Nicols de Hidalgo, Centro de Investigaciones y Estudios Avanzados del IPN (CINVESTAV) and Consejo Nacional de Ciencia y Tecnologa (CONACyT). We are very grateful to Dr Ral Arias Lovillo, Dr Vctor Manuel Alcarz Romero, Dr Asdrbal Flres Lpez and Mtro Walter Saiz Gonzlez, head of the Academic Secretariat, Director and Subdirector of the Office of Scientific Research and Director of the Division of Exact Sciences of the University of Veracruz, respectively, for their invaluable support in all senses to our Summer School. We also appreciate the important and useful assistance provided by Dr Rubn Bernardo Morante Lpez, Director of the Museum of Anthropology of Xalapa, and Dr Hctor Coronel Brizio of the Secretariat of Education and Culture of the state of Veracruz. We acknowledge the help of our colleagues in the Organizing Committee: Norma Bagatella Flores (FFIA-U. Veracruzana), Heriberto Castilla Valds (CINVESTAV-U. Zacatenco), Lorenzo Dz Cruz (FCFM-BUAP), Juan Jos Godina Nava (CINVESTAV-U. Zacatenco), Gerardo Herrera Corral (CINVESTAV-U. Zacatenco), German Mandujano Vallejo (FFIA-U. Veracruzana), Miguel ngel Prez Angn (CINVESTAV-U. Zacatenco), Efran Rojas Marcial (FFIA-U. Veracruzana) and Carlos Vargas Madrazo (FFIA-U Veracruzana). Many thanks also to our Conference Secretaries Patricia Carranza and Soledad Lpez for the efficiency with which they carried out their job and their dedication. Special thanks go to Mara Guadalupe Colorado Hernndez and Javier Ignacio Fragoso Tizapan, whose help in carrying out the School was essential, without their collaboration this School would not have been the same. We take this opportunity to thank most warmly all the speakers for delivering excellent lectures which made this event a success. Moreover, to our utmost delight, the students participated very enthusiastically and we hope that this school will contribute considerably towards their academic development. The future of scientific endeavour always depends upon the students. Adnan Bashir (IFM-UMSNH) Jens Erler (IF-UNAM) Rul Hernndez (FFIA-UV) Myriam Mondragn (IF-UNAM) Luis Villaseor (IFM-UMSNH)



Recommendations for the establishment of the seismic code of Haiti  

NASA Astrophysics Data System (ADS)

Haiti, because of his seismicity associated with plate boundary and several faults that cross the island of Hispaniola (Haiti-Dominican Republic), has been affected in the past by major earthquakes, which have caused loss of life and damage or considerable structural collapses (ex. 1771, 1842), sometimes the destruction of the cities. The recent earthquake of January 12, 2010, was the most destructive earthquake that any country has experienced in modern times, when we measure the number of people killed with respect to the population of a country (Cavallo et al. 2010). It's obvious that the major causes of theses losses are the lack of awareness of the population about the earthquakes, the absence of seismic code and quality control of the building. In this paper, we propose some recommendations for the establishment of the seismic code of Haiti in order to decrease physical and social impacts of earthquakes in the future. First of all, we present a theoretical part of concepts and fundamental elements to establish a seismic code, such as: description of the methodology for seismic hazard's assessment, presentation of the results in terms of acceleration maps for the whole country (in rock sites) and Uniform Hazard Spectrum (UHS) in the cities, and the criteria for soil classification and amplification factors for including site's effects, equivalent forces, etc. Then, we include a practical part where calculations and comparisons of five seismic codes of different countries (Eurocode 8, Spain, Canada, United States and Dominican Republic) are included, in order to have criteria for making the proposals for Haiti. Using the results of Benito et al (presented in this session S10) we compare the UHS in different cities of Haiti with the response spectrum derived from the application of the spectral shapes given by the aforementioned codes. Furthermore, the classification of soils and buildings have been also analyzed and contrasted with local data in order to propose the more suitable classification for Haiti. Finally, we have proposed a methodology for the forces estimation providing the values of the relevant coefficients.

Study of Galactic clumps with millimeter / submillimeter continuum and molecular emission: Early stages of massive star formation  

NASA Astrophysics Data System (ADS)

Massive stars play a key role in the evolution of the Galaxy; hence they are important objects of study in astrophysics. Although they are rare compared to low mass stars, they are the principal source of heavy elements and UV radiation, affecting the process of formation of stars and planets, and the physical, chemical, and morphological structure of galaxies. Star clusters form in dense "clumps" (few parsecs in size) within giant molecular clouds, while individual stars form in cores (subparsec scale). An important step in the observational study of massive star formation is the identification and characterization of clumps. More detailed studies can then show how these clumps fragment into cores. Studies of clumps in our Galaxy will provide fundamental guidelines for the analysis of other galaxies, where individual clumps and cores cannot be resolved, and provide a catalog of interesting sources for observations of the Milky Way with a new generation of instruments, such as the Atacama Large Millimeter/Submillimeter Array. Large-scale blind surveys of the Galactic plane at millimeter and submillimeter wavelengths have recently been completed, allowing us to identify star forming clumps and improve our understanding of the early stages of massive stars. One of these studies, the Bolocam Galactic Plane Survey (BGPS), mapped the continuum emission at 1.1 mm over a large region of the northern Galactic plane at a resolution of 33", identifying 8559 compact sources throughout the Galaxy. In this dissertation, I present observations of a sample of sources from the BGPS catalog, obtained with the Submillimeter High Angular Resolution Camera II (SHARC-II). I present in this work 107 continuum emission maps at 350 μm at high angular resolution (8.500) toward clump-like sources and construct a catalog of BGPS substructures. I estimate clump properties such as temperatures and multiplicity of substructures, and compare my results with 350 ?m continuum maps from the Hi-GAL survey. I also present a detailed analysis, using molecular line and dust continuum observations, of the region G331.5-0.1, one of the most luminous regions of massive star formation in the Milky Way, located at the tangent region of the Norma spiral arm. Molecular line and millimeter continuum emission maps reveal the presence of six compact and luminous molecular clumps, with physical properties consistent with values found toward other massive star forming sources. This work includes the discovery of one of the most energetic and luminous molecular outflows known in the Galaxy, G331.512-0.103. For this high-speed outflow, I present ALMA observations that reveal a very compact, extremely young bipolar outflow and a more symmetric outflowing shocked shell surrounding a very small region of ionized gas. The source is one of the youngest examples of massive molecular outflows associated with the formation of a high-mass star.

NASA Astrophysics Data System (ADS)

The fourth edition of the National Meeting on Chaos, Complex Systems and Time Series (NMCCSTS4), or in Spanish 4a. Reunin Nacional de Caos, Sistemas Complejos y Series de Tiempo, was held from 29 November to 2 December 2011 in the University of Veracruz (Universidad Veracruzana), Campus Xalapa, at Xalapa Veracruz, Mxico, in the beautiful House of the Lake (Casa del Lago), a late XIX century former textile factory situated in the edge of an also ancient former dam, currently a park containing three small lakes, very emblematic of Xalapa, City, the capital of the state of Veracruz, Mxico. The previous editions of this meeting, were held in Mrida (2006), Pachuca (2008) and Puebla (2009). A clear uptrend is observed in the number of participants in this academic event from all Universities of Mxico and abroad, going from about 15 participants in the first meeting to more than 90 in the last one. On this occasion, about 90 participants from three countries attended our event, where 29 papers (10 master lectures from top recognized national and international leaders in the fields of complexity, and 19 invited papers), one course for students and 42 posters were presented. A look at the scientific program of the NMCCSTS4, allows us to appreciate the wide range of topics and recent advances that were covered during our event; topics and recent results in the areas of biology, econophysics, sociophysics, genomics and bioinformatics, complex networks, thermodynamics, etc, were presented and discussed rigorously in a friendly, dynamical and informal atmosphere. Also, on this occasion, we celebrated Professor Miguel Angel Jimnez Montao, for his very distinguished academic career throughout more that 50 years and as a founding member of the Faculty of Physics and AI of University of Veracruz. Prizes were awarded for the best poster presentations. The winner was Porfirio Toledo, from Faculty of Mathematics, University of Veracruz (Game theory to characterize solutions of a discrete-time Hamilton--Jacobi equation). The present volume contains a rigorous selection of the lectures presented at the NMCCSTS4. All papers were peer reviewed and we consider the high quality and the wide range of topics covered here displays the high level that the community of complexity sciences is reaching in our country. We would like to thank all of the speakers, participants and the members of the Organizing Committee, also we would like to express our gratitude to all students and support personal involved with the logistic and technical aspects of the organization of our event. This IV edition of the National Meeting on Caos, Complex System and Time Series was sponsored by the following organizations and institutions, we warmly thank all of them: Universidad Veracruzana, IF-BUAP, UAM Azcapotzalco, INMEGEN, Conacyt (155492), all them from Mxico and the Ministero degli Affari Esteri (MAE) from Italy.

Properties of Waste from Coal Gasification in Entrained Flow Reactors in the Aspect of Their Use in Mining Technology / W?a?ciwo?ci odpadw ze zgazowania w?gla w reaktorach dyspersyjnych w aspekcie ich wykorzystania w technologiach grniczych  

NASA Astrophysics Data System (ADS)

Most of the coal gasification plants based of one of the three main types of reactors: fixed bed, fluidized bed or entrained flow. In recent years, the last ones, which works as "slagging" reactors (due to the form of generated waste), are very popular among commercial installations. The article discusses the characteristics of the waste from coal gasification in entrained flow reactors, obtained from three foreign installations. The studies was conducted in terms of the possibilities of use these wastes in mining technologies, characteristic for Polish underground coal mines. The results were compared with the requirements of Polish Standards for the materials used in hydraulic backfill as well as suspension technology: solidification backfill and mixtures for gob caulking. Wi?kszo?? przemys?owych instalacji zgazowania w?gla pracuje w oparciu o jeden z trzech g?wnych typw reaktorw: ze z?o?em sta?ym, dyspersyjny lub fluidalny. W zale?no?ci od rodzaju reaktora oraz szczeg?owych rozwi?za? instalacji, powstaj?ce uboczne produkty zgazowania mog? mie? r?n? posta?. Zale?y ona w du?ej mierze od stosunku temperatury pracy reaktora do temperatury topnienia cz??ci mineralnych zawartych w paliwie, czyli do temperatury mi?knienia i topnienia popio?u. W ostatnich latach bardzo du?? popularno?? w?rd instalacji komercyjnych zdobywaj? reaktory dyspersyjne "?u?luj?ce". W takich instalacjach ?u?el jest wychwytywany i studzony po wyp?yni?ciu z reaktora. W niektrych przypadkach oprcz ?u?la powstaje jeszcze popi? lotny, wychwytywany w systemach odprowadzania spalin. Mo?e by? on pozyskiwany oddzielnie lub te? zawracany do komory reaktora, gdzie ulega stopieniu. Wszystkie z analizowanych odpadw - trzy ?u?le oraz popi? pochodz? w?a?nie z tego typu instalacji. Tylko z jednej z nich pozyskano zarwno ?u?el jak i popi?, z pozosta?ych dwch jedynie ?u?el. Odpady te powsta?y, jako uboczny produkt zgazowania w?gla lub w?gla z dodatkami: bitumin (?u?el S1), czy biomasy (popi? A2, ?u?el S2). W polskim grnictwie podziemnym wyr?ni? mo?na kilka technologii podsadzkowych, w ktrych do transportu materia?u wykorzystywana jest woda. Tradycyjnie oraz ze wzgl?dw historycznych, terminem "podsadzka hydrauliczna" okre?la si? t?, ktra spe?nia wymagania normy PN-93/G-11010. Do najwa?niejszych cech takiej podsadzki hydraulicznej zaliczy? nale?y wype?nienia uprzednio wydzielonej pustki poeksploatacyjnej, materia?em o jak najmniejszej ?ci?liwo?ci oraz o jak najwi?kszej wodoprzepuszczalno?ci. Materia? taki, po odprowadzeniu wody ma stanowi? mechaniczna podpor? stropu, a proces podsadzania jest ?ci?le powi?zany z procesem eksploatacji, jako sposb likwidacji zrobw. Najcz??ciej stosowanymi materia?ami s? piasek podsadzkowy oraz odpady grnicze lub hutnicze (Lisowski, 1997). Od ponad dwudziestu lat, w polskim grnictwie w?gla kamiennego obecna jest rwnie? inna technologia podsadzkowa, w ktrej do transportu materia?w wykorzystywana jest woda. W tym przypadku cz??ci sta?e to materia?y drobnoziarniste, najcz??ciej popio?y r?nych typw, ktre po wymieszaniu z wod? tworz? zawiesin? (st?d termin "zawiesiny popio?owo-wodne"). Polska norma PN-G-11011:1998 wyr?nia dwie odmiany takich zawiesin i definiuje je, jako "podsadzk? zestalan?" oraz "mieszanin? do doszczelniania zrobw". Podstawow? ide? przy?wiecaj?c? stosowaniu zawiesin drobnoziarnistych w technologiach grniczych by?a pocz?tkowo troska o zagospodarowaniu odpadw energetycznych, a nast?pnie grniczych (Mazurkiewicz i in., 1998; Piotrowski i in., 2006; Piotrowski, 2010; Plewa i Mys?ek, 2000; Plewa i Sobota, 2002). Obecnie technologia zawiesinowa na sta?e zago?ci?a w kopalniach w?gla kamiennego staj?c si? nieodzownym ?rodkiem profilaktyki po?arowej i metanowej (Dziurzy?ski i Pomyka?a, 2006; Palarski, 2004; Pomyka?a, 2006).
