    HII regions are the archetypical tracers of high-mass star formation. Because of their high luminosities, they can be seen across the entire Galactic disk from mid-infrared to radio wavelengths. A uniformly sensitive survey of Galactic HII regions would allow us to constrain the properties of Galactic structure and star formation. We have cataloged over 8000 HII regions and candidates in the WISE Catalog of Galactic HII Regions (, but only 2000 of these are confirmed HII regions to date.To bring us closer to a complete census of high-mass star formation regions in the Milky Way, we have several ongoing observational campaigns. These efforts include (1) Green Bank Telescope radio recombination line (RRL) observations as part of the HII Region Discovery Survey (HRDS); (2) Australia Telescope Compact Array observations of southern HII region candidates in the Southern HII Region Discovery Survey (SHRDS); (3) Green Bank and Gemini North Telescope observations of star formation regions thought to reside at the edge of the star forming disk in the Outer Scutum-Centaurus Arm (OSC); and (4) Very Large Array continuum observations of the faintest HII region candidates in the second and third Galactic quadrants.Together, these observations will detect the RRL emission from all Galactic HII regions with peak cm-wavelength flux densities > 60mJy, establish the outer edge of Galactic high-mass star formation, and determine the number of HII regions in the Galaxy. The HRDS and SHRDS surveys have more than doubled the known population of Galactic HII regions. We use the OSC observations to determine the properties of high-mass star formation in the extreme outer Galaxy and our VLA observations to determine how many of our faint candidates are indeed HII regions. We combine the completeness limits we obtain through these HII region surveys with an HII region population synthesis model to estimate the total number of Galactic HII regions. From this, we

    HII regions, the zones of ionized gas surrounding recently formed high-mass stars, are the archetypical tracers of Galactic structure. The census of Galactic HII regions in the Southern sky is vastly incomplete due to a lack of sensitive radio recombination line (RRL) surveys. The Southern HII Region Discovery Survey (SHRDS) is a 900-hour Australia Telescope Compact Array cm-wavelength RRL and continuum emission survey of hundreds of third and fourth quadrant Galactic HII region candidates. These candidates are identified in the Widefield Infrared Survey Explorer (WISE) Catalog of Galactic HII Regions based on coincident 10 micron (WISE) and 20 cm (Southern Galactic Plane Survey) emission. The SHRDS is an extension of HII Region Discovery Surveys in the Northern sky with the Green Bank Telescope and Arecibo Telescope which discovered ~800 new HII regions. In the first 500 hours of the SHRDS, we targeted the 249 brightest HII region candidates and 33 previously known HII regions. We discuss the data reduction, analysis, and preliminary results from this first stage of the survey.

  3. Ultracompact HII regions associated with massive star formation

    Energy Technology Data Exchange (ETDEWEB)

    Wood, D.O.S.


    This dissertation establishes the physical properties of ultracompact (UC) HII regions and investigates their interaction with the interstellar medium. UC HII regions are small photoionized nebulae produced by massive stars embedded in clouds of molecular gas and dust. New observations have been made using the Very Large Array (VLA) at cm wavelengths and single dish telescopes at mm wavelengths. Data were also collected from the Infrared Astronomical Satellite (IRAS) and from the literature. It is shown that UC HII regions have electron densities {approx gt} 10{sup 4} cm{sup {minus}3}, emission measures {approx gt} 10{sup 7} pc cm{sup {minus}6} and diameters {approx lt} .01 pc. The VLA was used at 2 and 6 cm to identify 75 UC HII regions. Radio continuum brightness distributions with 0.4 inch resolution are presented in the form of contour plots. At high angular resolution five different morphologies were seen: spherical or unresolved (43%), cometary (20%), core-halo (16%), shell (4%) and irregular or multiply peaked (17%). Cometary UC HII regions may be produced by the bow shock of a star moving supersonically through the molecular gas. The total number of UC HII regions found is inconsistent with a UC HII region lifetime of <3 {times} 10{sup 4} years. It is shown that UC HII regions have a characteristic FIR flux density distribution that is very different from typical entries in the IRAS Point Source Catalog. A two-color selection criterion based on the known UC HII regions is developed and when applied to the entire PSC a total of 1708 embedded OB star candidates are found.

  4. The Infrared and Radio Fluxes Densities of Galactic HII Regions


    Makai, Z.; Anderson, L. D.; Mascoop, J. L.; Johnstone, B.


    We derive infrared and radio flux densities of all ~1000 known Galactic HII regions in the Galactic longitude range 17.5 < l < 65 degree. Our sample comes from the Wide-Field Infrared Survey Explorer (WISE) catalog of Galactic \\hii regions \\citep{anderson2014}. We compute flux densities at six wavelengths in the infrared (GLIMPSE 8 microns, WISE 12 microns and 22 microns, MIPSGAL 24 microns, and Hi-GAL 70 microns and 160 microns) and two in the radio (MAGPIS 20 cm and VGPS 21 cm). All HII reg...

    Context. Triggered star formation around H II regions could be an important process. The Galactic H II region RCW 79 is a prototypical object for triggered high-mass star formation. Aims: We aim to obtain a census of the young stellar population observed at the edges of the H II region and to determine the properties of the young sources in order to characterize the star formation processes that take place at the edges of this ionized region. Methods: We take advantage of Herschel data from the surveys HOBYS, "Evolution of Interstellar Dust", and Hi-Gal to extract compact sources. We use the algorithm getsources. We complement the Herschel data with archival 2MASS, Spitzer, and WISE data to determine the physical parameters of the sources (e.g., envelope mass, dust temperature, and luminosity) by fitting the spectral energy distribution. Results: We created the dust temperature and column density maps along with the column density probability distribution function (PDF) for the entire RCW 79 region. We obtained a sample of 50 compact sources in this region, 96% of which are situated in the ionization-compressed layer of cold and dense gas that is characterized by the column density PDF with a double-peaked lognormal distribution. The 50 sources have sizes of 0.1-0.4 pc with a typical value of 0.2 pc, temperatures of 11-26 K, envelope masses of 6-760 M⊙, densities of 0.1-44 × 105 cm-3, and luminosities of 19-12 712 L⊙. The sources are classified into 16 class 0, 19 intermediate, and 15 class I objects. Their distribution follows the evolutionary tracks in the diagram of bolometric luminosity versus envelope mass (Lbol-Menv) well. A mass threshold of 140 M⊙, determined from the Lbol-Menv diagram, yields 12 candidate massive dense cores that may form high-mass stars. The core formation efficiency (CFE) for the 8 massive condensations shows an increasing trend of the CFE with density. This suggests that the denser the condensation, the higher the fraction of its

    Using infrared, radio continuum, and spectral observations, we performed a detailed investigation of the H II region RCW175. We determined that RCW175, which actually consists of two separate H II regions, G29.1-0.7 and G29.0-0.6, is located at a distance of 3.2 {+-} 0.2 kpc. Based on the observations we infer that the more compact G29.0-0.6 is less evolved than G29.1-0.7 and was possibly produced as a result of the expansion of G29.1-0.7 into the surrounding interstellar medium. We compute a star formation rate for RCW175 of (12.6 {+-} 1.9) Multiplication-Sign 10{sup -5} M{sub Sun} yr{sup -1}, and identified six possible young stellar object candidates within its vicinity. Additionally, we estimate that RCW175 contains a total dust mass of 215 {+-} 53 M{sub Sun }. RCW175 has previously been identified as a source of anomalous microwave emission (AME), an excess of emission at centimeter wavelengths often attributed to electric dipole radiation from the smallest dust grains. We find that the AME previously detected in RCW175 is not correlated with the smallest dust grains (polycyclic aromatic hydrocarbons or small carbonaceous dust grains), but rather with the exciting radiation field within the region. This is a similar result to that found in the Perseus molecular cloud, another region which harbors AME, suggesting that the radiation field may play a pivotal role in the production of this new Galactic emission mechanism. Finally, we suggest that these observations may hint at the importance of understanding the role played by the major gas ions in spinning dust models.

  7. The Infrared and Radio Flux Densities of Galactic HII Regions (United States)

    Sandor Makai, Zoltan; Anderson, Loren Dean; Mascoop, Josh L.; Johnstone, Brittany


    We derive infrared and radio flux densities of all ~1000 known Galactic HII regions in the Galactic longitude range 17.5 = 0 and log10(F70/F12) >= 1.2, and log10(F24/F12) >= 0 and log10(F160/F70) =population is uncertain. Comparing with a sample of IR color indices from star-forming galaxies, HII regions show higher log10(F70/F12) ratios. We find a weak trend of decreasing infrared to ~20 cm flux density ratios with increasing Rgal, in agreement with previous extragalactic results, possibly indicating a decreased dust abundance in the outer Galaxy.We are using these flux densities to compute the total luminosity of the Milky Way. To achieve this, we sum the luminosity contributions from HII regions, point sources, diffuse thermal, and diffuse non-thermal emission at infrared and radio wavelengths. We compare our results with those from external galaxies to place the luminosity of the Milky Way into a galactic context.

  8. Properties of the HII Regions Derived Using Integral Field Spectroscopy

    Directory of Open Access Journals (Sweden)

    Sebastian F. Sánchez


    Full Text Available Here we review some of our more recent results on the observed properties of HII regions using Integral Field Spectroscopy. In particular, we illustrate the use of this technique to study in detail the ionization conditions across the nebulae for galactic HII regions (focused on the Orion Nebula and the statistical study of large samples of extragalactic HII regions. We review the reported new scaling relation between the local mass density and the oxygen abundance across the disk galaxies and the recently discovered universal gradient for oxygen abundances. We update our previous results the lack of a dependence of the Mass-Metallicity relation with the starformation rate, including new unpublished data. Finally we discuss on the relation between the ionization conditions in the nebulae and the underlying stellar population. All together our results indicate that disk galaxies present a chemical enrichment dominated by an inside-out growth scenario, with a less evident effect of radial migrations and/or outflows.

  9. A Complete VLA Census of the ~7000 Milky Way HII Regions (United States)

    Armentrout, William Paul; Anderson, Loren; Wenger, Trey V.; Balser, Dana; Bania, Thomas


    How many HII regions are in the Milky Way? Even with the success of recent surveys, we still do not have an adequate answer to this fundamental question. HII regions are the archetypical tracers of Galactic high-mass star formation, but population synthesis modeling indicates that their detection throughout the Galaxy is incomplete, biased toward the most luminous and nearby complexes. Using mid-infrared (MIR) data from the WISE satellite, we identified over 8000 HII regions and candidates, all of which share the characteristic morphology of 12 micron emission enveloping a core of 22 micron emission. Of these, nearly 4000 candidates have no detectable radio continuum emission from Galactic plane surveys and therefore their classification is unknown. These “radio quiet” candidates could represent a significant population of faint HII regions which are ionized by B-stars and/or are especially distant, or they might not be HII regions at all.We present here a survey of radio quiet HII regions in the second and third Galactic quadrants with the Very Large Array. This was the first systematic study of radio quiet HII region candidates. Nearly 60% of the 145 sources observed were detected by the VLA at X-band (10 GHz) to sub-mJy sensitivities. Coupled with their MIR morphologies, detection of continuum strongly indicate they are HII regions. If 60% of radio quiet candidates throughout the Galaxy prove to be HII regions, the number of expected HII regions in the Milky Way would more than double. Constraining the total number of HII regions within the Milky Way will feed back into stellar population synthesis modeling, informing both the high-mass tail of the Galactic star formation rate and the role of high-mass stars in the evolution of the ISM. We estimate there are between 6500 and 7000 HII regions in Milky Way created by a star of type B2 or earlier.

  10. Leaking Photons from the HII Region NGC 7538 (United States)

    Luisi, Matteo; Anderson, Loren D.; Balser, Dana S.; Bania, Thomas M.; Wenger, Trey


    Using data from the NRAO Green Bank Telescope and the INT Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS), we analyze the ionizing radiation that is escaping the photo-dissociation region (PDR) boundary of the HII region NGC 7538. We find extended radio continuum and radio recombination line (RRL) emission outside the PDR toward the north and east of the region. This suggests that a non-uniform PDR morphology is affecting the amount of radiation "leaking" through the PDR. We quantify the leaking photon fraction along the line of sight, and use a numerical model to estimate the leaking photon fraction in three dimensions of both radio continuum and H-alpha emission. We detect carbon RRL emission near the PDR and find a decrease in the helium-to-hydrogen ionic abundance ratio with increasing distance from the central position. This indicates a softening of the radiation field within the PDR. Using Herschel Space Observatory data, we create a dust temperature map of the region and show that small dust temperature enhancements to the north and east of NGC 7538 coincide with extended radio emission. We discuss implications for maintaining the ionization of the warm interstellar medium by HII regions.

  11. The Galactic HII Region Luminosity Function at Infrared and Radio Wavelengths (United States)

    Mascoop, Joshua; Anderson, Loren; Sandor Makai, Zoltan; Armentrout, William Paul


    HII regions are the clearest indicators of ongoing high-mass star formation. The HII region luminosity function (LF) therefore probes present global star formation properties, and its shape has been related to HII region properties and galaxy Hubble types. Most HII region LF studies to date have been conducted in external galaxies; due to observational difficulties, there have been relatively few studies of the Milky Way HII region LF. Using ~600 HII regions from the WISE Catalog of Galactic HII Regions, we examine the Galactic LF in the first quadrant. Our high-resolution view of Galactic star formation regions allows us to separate nearby sources, and our sample is complete for all HII regions ionized by single O9.5 stars.We analyze the Galactic LF at six infrared wavelengths - where the emission is due to dust - and also at 20 cm, where the emission is from ionized gas. All LFs have a similar shape, showing that infrared LFs can be used in place of ionized gas tracers. All LFs can be described by a single power law with an index of approximately -2, in agreement with previous studes. We find no compelling evidence of a break or "knee" in the LF. Moreover, we see no significant variation in the form of the LF as a function of heliocentric distance, HII region size, or Galactocentric radius.

    Kirsanova, M. S.; Sobolev, A. M.; Thomasson, M.; Wiebe, D. S.; Johansson, L. E. B.; Seleznev, A. F.


    We present a picture of star formation around the HII region Sh2-235 (S235) based upon data on the spatial distribution of young stellar clusters and the distribution and kinematics of molecular gas around S235. We observed 13CO(1-0) and CS(2-1) emission toward S235 with the Onsala Space Observatory 20-m telescope and analysed the star density distribution with archival data from the 2MASS survey. Dense molecular gas forms a shell-like structure at the south-eastern part of S235. The young cl...

  13. Mopra CO Observations of the Bubble H II Region RCW 120 (United States)

    Anderson, L. D.; Deharveng, L.; Zavagno, A.; Tremblin, P.; Lowe, V.; Cunningham, M. R.; Jones, P.; Mullins, A. M.; Redman, M. P.


    We use the Mopra radio telescope to test for expansion of the molecular gas associated with the bubble H II region RCW 120. A ring, or bubble, morphology is common for Galactic H II regions, but the three-dimensional geometry of such objects is still unclear. Detected near- and far-side expansion of the associated molecular material would be consistent with a three-dimensional spherical object. We map the J = 1 → 0 transitions of 12CO, 13CO, C18O, and C17O, and detect emission from all isotopologues. We do not detect the 00 → 1-1 E masing lines of CH3OH at 108.8939 GHz. The strongest CO emission is from the photo-dissociation region (PDR), and there is a deficit of emission toward the bubble interior. We find no evidence for expansion of the molecular material associated with RCW 120 and therefore can make no claims about its geometry. The lack of detected expansion is roughly in agreement with models for the time-evolution of an H II region like RCW 120, and is consistent with an expansion speed of leaking ~5% of the ionizing photons into the interstellar medium (ISM) through PDR holes at the locations of the temperature enhancements. Hα emission also shows a diffuse "halo" from leaked photons not associated with discrete holes in the PDR. Overall ~25% ± 10% of all ionizing photons are leaking into the nearby ISM.

  15. Forming a Primordial Star in a Relic HII Region

    Energy Technology Data Exchange (ETDEWEB)

    O' Shea, Brian


    There has been considerable theoretical debate over whether photoionization and supernova feedback from the first Population III stars facilitate or suppress the formation of the next generation of stars. We present results from an Eulerian adaptive mesh refinement simulation demonstrating the formation of a primordial star within a region ionized by an earlier nearby star. Despite the higher temperatures of the ionized gas and its flow out of the dark matter potential wells, this second star formed within 23 million years of its neighbor's death. The enhanced electron fraction within the HII region catalyzes rapid molecular hydrogen formation that leads to faster cooling in the subsequent star forming halos than in the first halos. This ''second generation'' primordial protostar has a much lower accretion rate because, unlike the first protostar, it forms in a rotationally supported disk of {approx} 10-100 M{center_dot}. In contrast to unpreprocessed regions, such configurations may allow binaries or multiple systems of lower mass stars to form. These first high resolution calculations offer insight into the impact of feedback upon subsequent populations of stars and clearly demonstrate how primordial chemistry promotes the formation of subsequent generations of stars even in the presence of the entropy injected by the first stars into the IGM.

    The detection of an excess of emission at microwave frequencies with respect to the predicted free–free emission has been reported for several Galactic H ii regions. Here, we investigate the case of RCW 49, for which the Cosmic Background Imager tentatively (∼3σ) detected Anomalous Microwave Emission (AME) at 31 GHz on angular scales of 7′. Using the Australia Telescope Compact Array, we carried out a multi-frequency (5, 19, and 34 GHz) continuum study of the region, complemented by observations of the H109α radio recombination line. The analysis shows that: (1) the spatial correlation between the microwave and IR emission persists on angular scales from 3.′4 to 0.″4, although the degree of the correlation slightly decreases at higher frequencies and on smaller angular scales; (2) the spectral indices between 1.4 and 5 GHz are globally in agreement with optically thin free–free emission, however, ∼30% of these are positive and much greater than −0.1, consistent with a stellar wind scenario; and (3) no major evidence for inverted free–free radiation is found, indicating that this is likely not the cause of the Anomalous Emission in RCW 49. Although our results cannot rule out the spinning dust hypothesis to explain the tentative detection of AME in RCW 49, they emphasize the complexity of astronomical sources that are very well known and studied, such as H ii regions, and suggest that, at least in these objects, the reported excess of emission might be ascribed to alternative mechanisms such as stellar winds and shocks.

  18. Emission-line Diagnostics of Nearby HII Regions Including Supernova Hosts (United States)

    Xiao, Lin; Eldridge, J. J.; Stanway, Elizabeth; Galbany, L.


    We present a new model of the optical nebular emission from HII regions by combining the results of the Binary Population and Spectral Synthesis (bpass) code with the photoionization code cloudy (Ferland et al. 1998). We explore a variety of emission-line diagnostics of these star-forming HII regions and examine the effects of metallicity and interacting binary evolution on the nebula emission-line production. We compare the line emission properties of HII regions with model stellar populations, and provide new constraints on their stellar populations and supernova progenitors. We find that models including massive binary stars can successfully match all the observational constraints and provide reasonable age and mass estimation of the HII regions and supernova progenitors.

  19. Investigation of the PAH size distribution in a compact HII region (United States)

    Ohsawa, Ryou


    Polycyclic aromatic hydrocarbons (PAHs) are excited by absorbing UV photons and emit the strong emission features in the infrared. The PAH emission features can be a good estimator of star formation rates (SFRs). On the other hand, PAHs are destroyed in harsh environments like HII regions. Two mechanisms are suggested for PAH destruction; sputtering and photo-dissociation. It is not observationally investigated which process is dominant in HII regions. We invent a method to identify the dominating destruction process in terms of the size distribution of PAHs. We propose the near-infrared imaging observations of a compact HII region M1-78 with the Gemini/NIRI. We investigate the variation in the PAH size distribution in M1-78 and discuss which destruction process is dominant in HII regions.

  1. NGC628 with SITELLE : I. Imaging Spectroscopy of 4285 HII region candidates. (United States)

    Rousseau-Nepton, L.; Robert, C.; Martin, R. P.; Drissen, L.; Martin, T.


    This is the first paper of a series dedicated to nebular physics and the chemical evolution of nearby galaxies by investigating large samples of HII regions with the CFHT imaging spectrograph SITELLE. We present a technique adapted to imaging spectroscopy to identify and extract parameters from 4285 HII region candidates found in the disc of NGC 628. Using both the spatial and spectral capabilities of SITELLE, our technique enables the extraction of the position, dust extinction, velocity, Hα profile, diffuse ionized gas (DIG) background, luminosity, size, morphological type, and the emission line fluxes for individual spaxels and the integrated spectrum for each region. We have produced a well-sampled HII region luminosity function and studied its variation with galactocentric radius and level of the DIG background. We found a slope α of -1.12 ±0.03 with no evidence of a break at high luminosity. Based on the width of the region profile, bright regions are rather compact, while faint regions are seen over a wide range of sizes. The radius function reveals a slope of -1.81 ±0.02. BPT diagrams of the individual spaxels and integrated line ratios confirm that most detections are HII regions. Also, maps of the line ratios show complex variations of the ionisation conditions within HII regions. All this information is compiled in a new catalogue for HII regions. The objective of this database is to provide a complete sample which will be used to study the whole parameter space covered by the physical conditions in active star-forming regions.

  2. Star formation towards the Galactic H II region RCW 120. Herschel observations of compact sources (United States)

    Context. The expansion of H II regions can trigger the formation of stars. An overdensity of young stellar objects is observed at the edges of H II regions but the mechanisms that give rise to this phenomenon are not clearly identified. Moreover, it is difficult to establish a causal link between H II -region expansion and the star formation observed at the edges of these regions. A clear age gradient observed in the spatial distribution of young sources in the surrounding might be a strong argument in favor of triggering. Aims: We aim to characterize the star formation observed at the edges of H II regions by studying the properties of young stars that form there. We aim to detect young sources, derive their properties and their evolution stage in order to discuss the possible causal link between the first-generation massive stars that form the H II region and the young sources observed at their edges. Methods: We have observed the Galactic H II region RCW 120 with Herschel PACS and SPIRE photometers at 70, 100, 160, 250, 350 and 500 μm. We produced temperature and H2 column density maps and use the getsources algorithm to detect compact sources and measure their fluxes at Herschel wavelengths. We have complemented these fluxes with existing infrared data. Fitting their spectral energy distributions with a modified blackbody model, we derived their envelope dust temperature and envelope mass. We computed their bolometric luminosities and discuss their evolutionary stages. Results: The overall temperatures of the region (without background subtraction) range from 15 K to 24 K. The warmest regions are observed towards the ionized gas. The coldest regions are observed outside the ionized gas and follow the emission of the cold material previously detected at 870 μm and 1.3 mm. The H2 column density map reveals the distribution of the cold medium to be organized in filaments and highly structured. Column densities range from 7 × 1021 cm-2 up to 9 × 1023 cm-2

  3. Dynamic UC HII regions in Sgr B2: Flickering and Ionized Flows (United States)

    De Pree, Christopher G.; Wilner, D. J.; Goss, M.; Mac Low, M.; Peters, T.; Klessen, R.; Keto, E. R.; Galvan-Madrid, R.; Banerjee, R.


    The Sgr B2 star forming region contains a large sample of ultracompact (UC) and hypercompact (HC) HII regions. The diversity of morphologies and number of unusual broad line sources make it an ideal laboratory for testing theories of UC HII region evolution. Recent high-resolution simulations that include heating from ionizing and non-ionizing radiation show that the dense, rotating, accretion flows required to form massive stars quickly become gravitationally unstable (Peters et al. 2010a). The orbits of these dense clumps and filaments near newly born massive stars irregularly trap and expose their ionizing radiation (Peters et al. 2010b). The resulting HII region flickers between HC and UC sizes throughout the main accretion phase, rather than monotonically expanding. Peters et al. (2010b) show that this model can solve the UC HII lifetime problem (Wood & Churchwell 1989), since accretion continues ten times longer than the free expansion timescale for an HII region. Imaged at 1.3 cm, the Sgr B2 region contains 49 regions, 25 of which are hypercompact, with physical diameters < 5000 AU (Gaume et al. 1995). In the past year, we have observed this large sample of UC HII regions in the Sgr B2 region with the EVLA in the three hybrid arrays in the 1.3-cm continuum and H66α and H68α lines with a resolution of 0.25''. We have also made continuum and RRL (H53α) observations at 7 mm in the BnA configuration to obtain morphological and line information at the highest available angular resolution of 0.06'' (650 AU). These new observations of Sgr B2 will allow us to: (1) Determine the frequency and magnitude of UC HII flux and size fluctuations over a 22 year time baseline (1989 to 2011) in one of the most source-rich massive star forming regions in the Milky Way, (2) Constrain and test the theoretical models described in Peters et al. (2010a, 2010b), (3) Observe recombination lines with the improved spectral resolution and bandwidth of the new EVLA correlator, and

A.; Okumura, K.; Pinheiro Gonçalves, D.; Polehampton, E.; Saraceno, P.; Sauvage, M.; Sidher, S.; Spencer, L.; Swinyard, B.; Ward-Thompson, D.; White, G. J.


    Context. RCW 120 is a well-studied, nearby Galactic H ii region with ongoing star formation in its surroundings. Previous work has shown that it displays a bubble morphology at mid-infrared wavelengths, and has a massive layer of collected neutral material seen at sub-mm wavelengths. Given the well-defined photo-dissociation region (PDR) boundary and collected layer, it is an excellent laboratory to study the “collect and collapse” process of triggered star formation. Using Herschel Space Observatory data at 100, 160, 250, 350, and 500 μm, in combination with Spitzer and APEX-LABOCA data, we can for the first time map the entire spectral energy distribution of an H ii region at high angular resolution. Aims: We seek a better understanding of RCW 120 and its local environment by analysing its dust temperature distribution. Additionally, we wish to understand how the dust emissivity index, β, is related to the dust temperature. Methods: We determine dust temperatures in selected regions of the RCW 120 field by fitting their spectral energy distribution (SED), derived using aperture photometry. Additionally, we fit the SED extracted from a grid of positions to create a temperature map. Results: We find a gradient in dust temperature, ranging from ⪆30 K in the interior of RCW 120, to ~20 K for the material collected in the PDR, to ~10 K toward local infrared dark clouds and cold filaments. There is an additional, hotter (~100 K) component to the dust emission that we do not investigate here. Our results suggest that RCW 120 is in the process of destroying the PDR delineating its bubble morphology. The leaked radiation from its interior may influence the creation of the next generation of stars. We find support for an anti-correlation between the fitted temperature and β, in rough agreement with what has been found previously. The extended wavelength coverage of the Herschel data greatly increases the reliability of this result. Herschel is an ESA space

  5. Optical polarimetric and near-infrared photometric study of the RCW95 Galactic H II region (United States)

    Vargas-González, J.; Roman-Lopes, A.; Santos, F. P.; Franco, G. A. P.; Santos, J. F. C.; Maia, F. F. S.; Sanmartim, D.


    We carried out an optical polarimetric study in the direction of the RCW 95 star-forming region in order to probe the sky-projected magnetic field structure by using the distribution of linear polarization segments which seem to be well aligned with the more extended cloud component. A mean polarization angle of θ = 49.8° ± 7.7°7 was derived. Through the spectral dependence analysis of polarization it was possible to obtain the total-to-selective extinction ratio (RV) by fitting the Serkowski function, resulting in a mean value of RV = 2.93 ± 0.47. The foreground polarization component was estimated and is in agreement with previous studies in this direction of the Galaxy. Further, near-infrared (NIR) images from Vista Variables in the Via Láctea (VVV) survey were collected to improve the study of the stellar population associated with the H II region. The Automated Stellar Cluster Analysis algorithm was employed to derive structural parameters for two clusters in the region, and a set of PAdova and TRieste Stellar Evolution Code (PARSEC) isochrones was superimposed on the decontaminated colour-magnitude diagrams to estimate an age of about 3 Myr for both clusters. Finally, from the NIR photometry study combined with spectra obtained with the Ohio State Infrared Imager and Spectrometer mounted at the Southern Astrophysics Research Telescope we derived the spectral classification of the main ionizing sources in the clusters associated with IRAS 15408-5356 and IRAS 15412-5359, both objects classified as O4V stars.

  6. A multiwavelength study of star formation in the vicinity of Galactic HII region Sh2-100


    Samal, M. R.; Pandey, A. K.; Ojha, D. K.; Ghosh, S.K.; Kulkarni, V. K.; Kusakabe, N.; Tamura, M; Bhatt, B. C.; Thompson, M.A.; Sagar, R


    We present multiwavelength investigation of morphology, physical-environment, stellar contents and star formation activity in the vicinity of star-forming region Sh 2-100. It is found that the Sh 2-100 region contains seven HII regions of ultracompact and compact nature. The present estimation of distance for three HII regions, along with the kinematic distance for others, suggests that all of them belong to the same molecular cloud complex. Using NIR photometry, we identified the most probab...

  7. Narrow-band {H}β images of star-formation regions in HII galaxies (United States)

    Lagos, P.; Telles, E.; Melnick, J.


    Aims:Create a catalog of images of HII galaxies and their individual star-formation regions in order to study the distribution of the gas emission and their underlying stellar continuum. Methods: We have used Hβ narrow-band images of 43 selected HII galaxies obtained at ESO NTT 3.58 m telescope using the SUSI2 camera. Results: Surface photometric Hβ fluxes and equivalent widths for all objects and star-formation regions are presented in this catalog. A myriad of filamentary structure were found in the pure Hβ emission-line or continuum-subtracted images, probably attributed to expanding shells as a consequence of the star-formation activity. Our results indicate that the number of regions with high Hβ equivalent width or young regions increase with the instrumental resolution, showing that the instrumental resolution is a bias to determine the cluster ages. Therefore, we showed that some of the observed giant HII regions may have been formed by ensembles of unresolved star forming regions or candidates to host Super Star Clusters. Pure Hβ emission-line images, continuum contours and EW(Hβ) maps showing the morphology of the gaseous and stellar emission in HII galaxies and their individual star-formation regions were obtained. All calibrated continuum and Hβ emission line fluxes and the derived Hβ equivalent width images are available in fits format from Based on observations made with ESO NTT 3.5 m Telescope at the La Silla Observatory under programmen ID and .

  8. A SCUBA imaging survey of ultracompact HII regions. The environments of massive star formation (United States)

    Thompson, M. A.; Hatchell, J.; Walsh, A. J.; MacDonald, G. H.; Millar, T. J.


    We present a SCUBA submillimetre (450 and 850 μm) survey of the environment of 105 IRAS point sources, selected from the Wood & Churchwell (1989a) and Kurtz et al. (1994) radio ultracompact (UC) Hii region surveys. We detected a total of 155 sub-mm clumps associated with the IRAS point sources and identified three distinct types of object: ultracompact cm-wave sources that are not associated with any sub-mm emission (sub-mm quiet objects), sub-mm clumps that are associated with ultracompact cm-wave sources (radio-loud clumps); and sub-mm clumps that are not associated with any known ultracompact cm-wave sources (radio-quiet clumps). 90% of the sample of IRAS point sources were found to be associated with strong sub-mm emission. We consider the sub-mm colours, morphologies and distance-scaled fluxes of the sample of sub-mm clumps and show that the sub-mm quiet objects are unlikely to represent embedded UC Hii regions unless they are located at large heliocentric distances. Many of the 2.5 arcmin SCUBA fields contain more than one sub-mm clump, with an average number of companions (the companion clump fraction) of 0.90. The clumps are more strongly clustered than other candidate HMPOs and the mean clump surface density exhibits a broken power-law distribution with a break at 3 pc. We demonstrate that the sub-mm and cm-wave fluxes of the majority of radio-loud clumps are in excellent agreement with the standard model of ultracompact Hii regions. We speculate on the nature of the radio-quiet sub-mm clumps and, whilst we do not yet have sufficient data to conclude that they are in a pre-UC Hii region phase, we argue that their characteristics are suggestive of such a stage.

  10. High-mass star formation possibly triggered by cloud-cloud collision in the H II region RCW 34 (United States)

    We report on the possibility that the high-mass star located in the H II region RCW 34 was formed by a triggering induced by a collision of molecular clouds. Molecular gas distributions of the 12CO and 13CO J = 2-1 and 12CO J = 3-2 lines in the direction of RCW 34 were measured using the NANTEN2 and ASTE telescopes. We found two clouds with velocity ranges of 0-10 km s-1 and 10-14 km s-1. Whereas the former cloud is as massive as ˜1.4 × 104 M⊙ and has a morphology similar to the ring-like structure observed in the infrared wavelengths, the latter cloud, with a mass of ˜600 M⊙, which has not been recognized by previous observations, is distributed to just cover the bubble enclosed by the other cloud. The high-mass star with a spectral type of O8.5V is located near the boundary of the two clouds. The line intensity ratio of 12CO J = 3-2/J = 2-1 yields high values (≳1.0), suggesting that these clouds are associated with the massive star. We also confirm that the obtained position-velocity diagram shows a similar distribution to that derived by a numerical simulation of the supersonic collision of two clouds. Using the relative velocity between the two clouds (˜5 km s-1), the collisional time scale is estimated to be ˜0.2 Myr with the assumption of a distance of 2.5 kpc. These results suggest that the high-mass star in RCW 34 was formed rapidly within a time scale of ˜0.2 Myr via a triggering of a cloud-cloud collision.

    We present a SCUBA submillimetre (450 & 850 micron) survey of the environment of 105 IRAS point sources, selected from the Wood & Churchwell (1989a) and Kurtz, Churchwell & Wood (1994) radio ultracompact (UC) HII region surveys. We detected a total of 155 sub-mm clumps associated with the IRAS point sources and identified three distinct types of object: ultracompact cm-wave sources that are not associated with any sub-mm emission (sub-mm quiet objects), sub-mm clumps that are associated with ...

  12. Morphologies of Ultracompact HII Regions in W49A and Sgr B2: Prevalence of Shells and a Modified Classification Scheme


    De Pree, C. G.; Wilner, D. J.; Deblasio, J.; Mercer, A. J.; Davis, L. E.


    We have used Very Large Array (VLA) observations of the massive star forming regions W49A and Sgr B2, obtained with resolutions from 2\\farcs0 to 0\\farcs04, to classify the morphologies of nearly 100 ultracompact HII regions. These high resolution, multi-frequency, multi-configuration VLA observations motivate several modifications of the existing morphological classification scheme for UC HII regions. In this work, we describe the modified morphology scheme and the criteria used in source cla...

  13. The relation between radio flux density and ionizing ultra-violet flux for HII regions and supernova remnants in the Large Magellanic cloud

    Directory of Open Access Journals (Sweden)

    Filipović M.D.


    Full Text Available We present a comparison between the Parkes radio surveys (Filipović et al 1995 and Vacuum Ultra-Violet (VUV surveys (Smith et al. 1987 of the Large Magellanic Clouds (LMC. We have found 72 sources in common in the LMC which are known HII regions (52 and supernova remnants (SNRs (19. Some of these radio sources are associated with two or more UV stellar associations. A comparison of the radio flux densities and ionizing UV flux for HII regions shows a very good correlation, as expected from theory. Many of the Magellanic Clouds (MCs SNRs are embedded in HII regions, so there is also a relation between radio and UV which we attribute to the surrounding HII regions.

  14. ISO Mid-Infrared Observations of Giant HII Regions in M33 (United States)

    Skelton, B. P.; Waller, W. H.; Hodge, P. W.; Boulanger, F.; Cornett, R. H.; Fanelli, M. N.; Lequeux, J.; Stecher, T. P.; Viallefond, F.; Hui, Y.


    We present Infrared Space Observatory Camera (ISOCAM) Circular Variable Filter scans of three giant HII regions in M33. IC 133, NGC 595, and CC 93 span a wide range of metallicity, luminosity, nebular excitation, and infrared excess; three other emission regions (CC 43, CC 99, and a region to the northeast of the core of NGC 595) are luminous enough in the mid-infrared to be detected in the observed fields. ISOCAM CVF observations provide spatially resolved observations (5'') of 151 wavelengths between 5.1 and 16.5 microns with a spectral resolution R = 35 to 50. We observe atomic emission lines ([Ne II], [Ne III], and [S IV]), several "unidentified infrared bands" (UIBs; 6.2, 7.7, 8.6, 11.3, 12.0, and 12.7 microns), and in some cases a continuum which rises steeply at longer wavelengths. We conclude that the spectra of these three GHRs are well explained by combinations of ionized gas, PAHs, and very small grains in various proportions and with different spatial distributions. Comparisons between observed ratios of the various UIBs with model ratios indicate that the PAHs in all three of the GHRs are dehydrogenated and that the small PAHs have been destroyed in IC 133 but have survived in NGC 595 and CC 93. The [Ne III]/[Ne II] ratios observed in IC 133 and NGC 595 are consistent with their ages of 5 and 4.5 Myr, respectively; the deduced ionization parameter is higher in IC 133, consistent with its more compact region of emission.

  15. Massive Star Formation in NGC4038/4039: HII Regions and Supernova Remnants in "The Antennae" (United States)

    Neff, S. G.; Ulvestad, J. S.; Fisher, Richard (Technical Monitor)


    The nearest merger, NGC4038/4039 ("The Antennae, Arp244), is undergoing a starburst apparently triggered and driven by the ongoing interaction. The system provides an excellent laboratory to study star formation processes because well-studied and nearby (21 Mpc assumed here). Models of the interaction suggest that the interaction's first periapse occurred 200 Myr ago, and that final coalescence will occur in another 100 Myr. Blue and H alpha images show a continuous loop of bright knots around the NGC4038 (northern) nucleus, continuing down through the NGC4039 (southern) nucleus. Recent HST V and I images resolve the star-forming knots into several thousand blue compact clusters, with ages 5Myr for the youngest clusters. Far Ultraviolet (lambda 1500A) observations directly detect O and B stars in regions of low extinction; the total mass of young stars so observed is approximately 8 x 10 (exp 5) solar mass. FIR observations imply a star formation rate of approximately 5 M (sub 0) dot yr (sup -1) or greater. We used the VLA at 6 and 4 cm to obtain high resolution radio images of the star-formation regions in NGC4038/4038. We used high resolution imaging to identify compact radio emitting regions and spectral indices of the compact regions to differentiate between thermal sources such as HII regions (flat spectra) and supernova, remnants (steep spectra). We found that compact radio sources produce approximately 12% and/sim 25 strongest radio emission occurs between the galaxies, at an optically unremarkable location near but not coincident with an extremely red cluster. The radio peak is at a location of intense star formation (as detected in the mid-IR, reference?) and of dense molecular gas. We identify 115 individual compact 6cm radio sources and 63 individual 4 cm sources in the system, to a limiting luminosity of approximately 2 x 10 (exp 1) 8 W Hz (sup -1) (or /sim4x the luminosity of Cas A). Of the strongest sources, for which the h flux densities are large

  16. Integral field spectroscopy of the two complexes of HII regions in the main galaxy of the minor merger AM2306-721 (United States)

    Hernandez-Jimenez, J. A.; Pastoriza, G.; Sanmartim, D.; Winge, C.; Bonatto, C.; Krabbe, A. C.; Rodrigues, I.


    We present a study of two complexes of HII regions in the main galaxy of minor merger AM 2306-721. The observations were obtained with the GMOS-IFU on the Gemini South telescope. By using different discrimination criteria, we determined that shock-ionized gas fraction ranges between 0% and 35%, which are in good agreement with numerical models. Thus, we conclude that almost all the mechanical energy from stellar winds and supernovae is being irradiated.

  18. Production of Elephant Trunks in HII Regions by Radiation-Magnetohydrodynamic Instabilities


    Fierlinger, Katharina; Krumholz, Mark; Grittschneder, Matthias


    Recent SPH and grid code simulations showed, that ionizing radiation can amplify overdensities in turbulent molecular clouds and produce molecular pillars. The relevance of magnetic fields for the structure and stability of molecular clouds is still under discussion. We investigate whether an ionization front hitting a medium with small distortions of the magnetic field can produce the observed pillar-like structures in star forming regions (e.g. Eagle Nebula). Numerical MHD simulations with ...

  19. RCW 108: Massive Young Stars Trigger Stellar Birth (United States)


    RCW 108 is a region where stars are actively forming within the Milky Way galaxy about 4,000 light years from Earth. This is a complicated region that contains young star clusters, including one that is deeply embedded in a cloud of molecular hydrogen. By using data from different telescopes, astronomers determined that star birth in this region is being triggered by the effect of nearby, massive young stars. This image is a composite of X-ray data from NASA's Chandra X-ray Observatory (blue) and infrared emission detected by NASA's Spitzer Space Telescope (red and orange). More than 400 X-ray sources were identified in Chandra's observations of RCW 108. About 90 percent of these X-ray sources are thought to be part of the cluster and not stars that lie in the field-of-view either behind or in front of it. Many of the stars in RCW 108 are experiencing the violent flaring seen in other young star-forming regions such as the Orion nebula. Gas and dust blocks much of the X-rays from the juvenile stars located in the center of the image, explaining the relative dearth of Chandra sources in this part of the image. The Spitzer data show the location of the embedded star cluster, which appears as the bright knot of red and orange just to the left of the center of the image. Some stars from a larger cluster, known as NGC 6193, are also visible on the left side of the image. Astronomers think that the dense clouds within RCW 108 are in the process of being destroyed by intense radiation emanating from hot and massive stars in NGC 6193. Taken together, the Chandra and Spitzer data indicate that there are more massive star candidates than expected in several areas of this image. This suggests that pockets within RCW 108 underwent localized episodes of star formation. Scientists predict that this type of star formation is triggered by the effects of radiation from bright, massive stars such as those in NGC 6193. This radiation may cause the interior of gas clouds in RCW 108 to

  1. SN 185 and its Remnant RCW 86: A Type Ia Explosion within a Bubble? (United States)

    Borkowski, Kazimierz; Blair, William; Ghavamian, Parviz; Long, Knox; Raymond, John; Reynolds, Stephen; Rho, Jeonghee; Williams, Brian; Winkler, P. Frank


    The bright guest star of AD185 is the earliest recorded historical supernova (SN), but its remnant has only recently been firmly identified with RCW 86 with help of X-rays and very high energy (VHE) Gamma-rays. RCW 86 is unlike any other historical SN, implicating a Type Ia explosion within a wind-blown bubble. X-ray synchrotron emission and VHE Gamma-rays are produced by relativistic particles accelerated in fast (several thousand km/s) shocks that are present in RCW 86, while slower radiative and nonradiative shocks are driven into the dusty shell swept up by the SN progenitor. We propose Spitzer observations of RCW 86, that will allow us to determine dust properties and physical conditions within both slow and fast shocks. We will determine shock densities in the whole remnant using MIPS imaging at 24 and 70 microns. This will allow us to finally determine whether VHE emission arises from relativistic electrons or from cosmic ray protons accelerated by the SN shock. We will also determine how acceleration of synchrotron-emitting electrons to TeV energies depends on the shock density. We propose IRS spectral mapping in two very different regions of the remnant to perform a more detailed and sensitive study of dust emission and dust destruction under differing plasma conditions, and of line emission produced by radiative shocks. This will also verify the results of the imaging observations, and will allow for quantitative comparison with models for dust emission and destruction in SN shocks. We request imaging with IRAC in the brightest region of the remnant to map emission from the hottest, transiently heated small grains, and to determine their destruction rates. Physical properties and dust content within the shell swept up by the RCW 86 progenitor will help us to constrain the pre-SN evolution of a Type Ia progenitor, a significant step toward understanding of progenitors of thermonuclear explosions.

  3. The Northern Rims of SNR RCW 86 Chandras Recent Observations and their Implications for Particle Acceleration (United States)

    Castro, Daniel


    The Chandra observations towards the northwest (NW) and northeast (NE) rims of supernova remnant (SNR) RCW 86 reveal great detail about the characteristics of the shocks, particle acceleration and the local environments in these 2 distinct regions. Both the NW and NE of RCW 86 show clear evidence of non-thermal X-ray emission, identified as synchrotron radiation from shock-accelerated electrons with TeV energies, interacting with the compressed, and probably amplified, local magnetic field.Magnetic field amplification (MFA) is broadly believed to result from, and contribute to, cosmic ray acceleration at the shocks of SNRs. However, we still lack a detailed understanding of the particle acceleration mechanism, and with this study we address the connection between the shock properties and ambient medium with MFA. The Chandra observations of RCW 86 allowed us to constrain the magnitude of the post- shock magnetic field in the NE and NW rims by deriving synchrotron filament widths, and also the densities in these regions, using thermal emission co-located with the non-thermal rims. I will discuss our analysis in detail and comment on how MFA appears to be related to certain characteristics of the SNR shock.

  5. Estudo da região HII galática NGC 2579 (United States)

    Riffel, R.; Copetti, M. V. F.


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

  6. The extraordinary outburst in the massive protostellar system NGC6334I-MM1: dimming of the hypercompact HII region and destruction of water masers (United States)

    Brogan, Crystal; Hunter, Todd Russell


    I will present results from multi-epoch JVLA 1.3 and 0.7 cm observations of the massive protostellar outburst in NGC6334I-MM1. The continuum data reveal that as of 2016, the free-free emission from the central protostar dropped by a factor of 5 since 2011, likely in response to the outburst observed in the millimeter continuum that began in 2015. Additionally, the water maser emission toward MM1 has dramatically reduced. In contrast, the water masers in other locations in the protocluster have flared, with the strongest spots associated with CM2, a non-thermal radio source that appears to mark a shock aligned with a jet emanating northward from MM1. The pre-outburst luminosity and HCHII region are consistent with a deeply-embedded central object having a spectral type of B3 (ZAMS). The observed quenching of the HCHII region suggests a reduction in uv photon production due either to an elevated disk-mediated accretion rate that is ongoing, or the rapid accretion of a substantial mass (0.1 Msun) which has caused the protostellar photosphere to expand and radiate at a much larger luminosity, but with a lower effective temperature. These data demonstrate the need for higher sensitivity and higher angular resolution ~1 cm centimeter observations, as enabled by the ngVLA, to trace the evolution of massive protostellar accretion.

    RCW 120 is a Galactic H ii region that has a beautiful ring shape that is bright in the infrared. Our new CO J = 1–0 and J = 3–2 observations performed with the NANTEN2, Mopra, and ASTE telescopes have revealed that two molecular clouds with a velocity separation of 20 km s{sup −1} are both physically associated with RCW 120. The cloud at −8 km s{sup −1} apparently traces the infrared ring, while the other cloud at −28 km s{sup −1} is distributed just outside the opening of the infrared ring, interacting with the H ii region as suggested by the high kinetic temperature of the molecular gas and by the complementary distribution with the ionized gas. A spherically expanding shell driven by the H ii region is usually considered to be the origin of the observed ring structure in RCW 120. Our observations, however, indicate no evidence of the expanding motion in the velocity space, which is inconsistent with the expanding shell model. We postulate an alternative that, by applying the model introduced by Habe and Ohta, the exciting O star in RCW 120 was formed by a collision between the present two clouds at a collision velocity of ∼30 km s{sup −1}. In the model, the observed infrared ring can be interpreted as the cavity created in the larger cloud by the collision, whose inner surface is illuminated by the strong ultraviolet radiation after the birth of the O star. We discuss that the present cloud–cloud collision scenario explains the observed signatures of RCW 120, i.e., its ring morphology, coexistence of the two clouds and their large velocity separation, and absence of the expanding motion.

    Recent studies of massive-star forming regions indicate that they can contain multiple generations of young stars. These observations suggest that star formation in these regions is sequential and/or triggered by a previous generation of (massive) stars. Here we present new observations of the star

  9. The low-mass content of the massive young star cluster RCW 38 (United States)

    Mužić, Koraljka; Schödel, Rainer; Scholz, Alexander; Geers, Vincent C.; Jayawardhana, Ray; Ascenso, Joana; Cieza, Lucas A.


    RCW 38 is a deeply embedded young (˜1 Myr), massive star cluster located at a distance of 1.7 kpc. Twice as dense as the Orion nebula cluster, orders of magnitude denser than other nearby star-forming regions and rich in massive stars, RCW 38 is an ideal place to look for potential differences in brown dwarf formation efficiency as a function of environment. We present deep, high-resolution adaptive optics data of the central ˜0.5 × 0.5 pc2 obtained with NACO at the Very Large Telescope. Through comparison with evolutionary models, we determine masses and extinction for ˜480 candidate members, and derive the first initial mass function (IMF) of the cluster extending into the substellar regime. Representing the IMF as a set of power laws in the form dN/dM ∝ M-α, we derive the slope α = 1.60 ± 0.13 for the mass range 0.5-20 M⊙,which is shallower than the Salpeter slope, but in agreement with results in several other young massive clusters. At the low-mass side, we find α = 0.71 ± 0.11 for masses between 0.02 and 0.5 M⊙, or α = 0.81 ± 0.08 for masses between 0.02 and 1 M⊙. Our result is in agreement with the values found in other young star-forming regions, revealing no evidence that a combination of high stellar densities and the presence of numerous massive stars affects the formation efficiency of brown dwarfs and very-low-mass stars. We estimate that the Milky Way galaxy contains between 25 and 100 billion brown dwarfs (with masses >0.03 M⊙).

  11. A Systematic Study of the Thermal and Nonthermal Emission in the Supernova Remnant RCW 86 with Suzaku (United States)

    Tsubone, Yoshio; Sawada, Makoto; Bamba, Aya; Katsuda, Satoru; Vink, Jacco


    Diffusive shock acceleration by the shockwaves in supernova remnants (SNRs) is widely accepted as the dominant source for Galactic cosmic rays. However, it is unknown what determines the maximum energy of accelerated particles. The surrounding environment could be one of the key parameters. The SNR RCW 86 shows both thermal and nonthermal X-ray emission with different spatial morphologies. These emission originate from the shock-heated plasma and accelerated electrons respectively, and their intensities reflect their density distributions. Thus, the remnant provides a suitable laboratory to test possible association between the acceleration efficiency and the environment. In this paper, we present results of spatially resolved spectroscopy of the entire remnant with Suzaku. The spacially resolved spectra are well reproduced with a combination of a power-law for synchrotron emission and a two-component optically thin thermal plasma, corresponding to the shocked interstellar medium (ISM) with kT of 0.3-0.6 keV and Fe-dominated ejecta. It is discovered that the photon index of the nonthermal component becomes smaller when decreasing the emission measure of the shocked ISM, where the shock speed has remained high. This result implies that the maximum energy of accelerated electrons in RCW 86 is higher in the low-density and higher shock speed regions.

  12. Biochemical characterization of RNase HII from Aeropyrum pernix. (United States)

    Aeropyrum pernix contains one homolog of ribonuclease H (RNase H), A. pernix RNase HII (Ape-RNase HII). Activity characterization showed that Ape-RNase HII exhibited the highest activity in the presence of 5 mM Mn(2+), 1 mM Co(2+), or 10 mM Mg(2+), respectively; however, its cleavage efficiencies at different cleavage sites for Mn(2+) and Mg(2+) were different. Ape-RNase HII cleaved 12-bp RNA/DNA substrates at multiple sites and the optimum pH value was 11.0. Moreover, 16-bp DNA-r4-DNA/DNA and 13-bp DNA-r1-DNA/DNA chimeric substrates were cleaved at DNA-RNA junction. Ape-RNase HII was thermostable and the stabilization was enhanced with increased salt concentration. This work is believed to be the first in vitro functional study of Ape-RNase HII and the results should contribute to the analysis of RNase H of other archaeal species.

  13. Understanding the Links among the Magnetic Fields, Filament, Bipolar Bubble, and Star Formation in RCW 57A Using NIR Polarimetry (United States)

    Eswaraiah, Chakali; Lai, Shih-Ping; Chen, Wen-Ping; Pandey, A. K.; Tamura, M.; Maheswar, G.; Sharma, S.; Wang, Jia-Wei; Nishiyama, S.; Nakajima, Y.; Kwon, Jungmi; Purcell, R.; Magalhães, A. M.


    The influence of magnetic fields (B-fields) on the formation and evolution of bipolar bubbles, due to the expanding ionization fronts (I-fronts) driven by the H II regions that are formed and embedded in filamentary molecular clouds, has not been well-studied yet. In addition to the anisotropic expansion of I-fronts into a filament, B-fields are expected to introduce an additional anisotropic pressure, which might favor the expansion and propagation of I-fronts forming a bipolar bubble. We present results based on near-infrared polarimetric observations toward the central ˜8‧ × 8‧ area of the star-forming region RCW 57A, which hosts an H II region, a filament, and a bipolar bubble. Polarization measurements of 178 reddened background stars, out of the 919 detected sources in the JHK s bands, reveal B-fields that thread perpendicularly to the filament long axis. The B-fields exhibit an hourglass morphology that closely follows the structure of the bipolar bubble. The mean B-field strength, estimated using the Chandrasekhar-Fermi method (CF method), is 91 ± 8 μG. B-field pressure dominates over turbulent and thermal pressures. Thermal pressure might act in the same orientation as the B-fields to accelerate the expansion of those I-fronts. The observed morphological correspondence among the B-fields, filament, and bipolar bubble demonstrate that the B-fields are important to the cloud contraction that formed the filament, to the gravitational collapse and star formation in it, and in feedback processes. The last one includes the formation and evolution of mid-infrared bubbles by means of B-field supported propagation and expansion of I-fronts. These may shed light on preexisting conditions favoring the formation of the massive stellar cluster in RCW 57A.

    An unmanned winged vehicle to be lauched by the H-II rocket, the H-II Orbiting Plane (HOPE), is described. HOPE will be launched into a 250-km altitude orbit, will remain in space for 1 to 3 days (performing experiments or rendezvous and docking to the space station), and will then return to land on a runway automatically. A double delta wing design was selected, along with tip fins for the tail. Trade-off studies were performed for airframe structural materials, thermal protection system materials, the guidance, navigation, and control system, and the development of fuel cells.

  16. The Refined Shock Velocity of the X-Ray Filaments in the RCW 86 Northeast Rim (United States)

    Yamaguchi, Hiroya; Katsuda, Satoru; Castro, Daniel; Williams, Brian J.; Lopez, Laura A.; Slane, Patrick O.; Smith, Randall K.; Petre, Robert


    A precise measurement of shock velocities is crucial for constraining the mechanism and efficiency of cosmic-ray (CR) acceleration at supernova remnant (SNR) shock fronts. The northeastern rim of the SNR RCW 86 is thought to be a particularly efficient CR acceleration site, owing to the recent result in which an extremely high shock velocity of 6000 km s1 was claimed. Here, we revisit the same SNR rim with the Chandra X-ray Observatory, 11 years after the first observation. This longer baseline than previously available allows us to determine a more accurate proper motion of the nonthermal X-ray filament, revealing a much lower velocity of 3000 340 km s1 (and even slower at a brighter region). Although the value has dropped to one-half of that from the previous X-ray measurement, it is still higher than the mean velocity of the H filaments in this region (1200 km s1). This discrepancy implies that the filaments bright in nonthermal X-rays and H emission trace different velocity components, and thus a CR pressure constrained by combining the X-ray kinematics and the H spectroscopy can easily be overestimated. We also measure the proper motion of the thermal X-ray filament immediately to the south of the nonthermal one. The inferred velocity (720 360 km s1) is significantly lower than that of the nonthermal filament, suggesting the presence of denser ambient material, possibly a wall formed by a wind from the progenitor, which has drastically slowed down the shock.

    Moderator subcooling margin has been analyzed using the MODTURC{sub C}LAS code in the Large LOCA FSAR PARTs C and F. Performance of moderator heat exchangers depends on RCW (Raw reCirculated Water) temperature. And also the temperature is affected by sea water temperature. Unfortunately, sea water temperature is gradually increasing by global warming. So it will cause increase of RCW temperature inevitably. There is no assessment result of moderator subcooling with increasing RCW temperature even if it is important problem. Therefore, sensitivity analysis is performed to give information about the relation between RCW temperature and moderator subcooling in the present study. The moderator subcooling margin has to be ensured to establish the moderator heat removal when Large LOCA with LOECI and Loss of Class IV Power occurs. However, sea water temperature is increasing gradually due to global warming. So it is necessary that sensitivity analysis of RCW temperature on the moderator subcooling margin to estimate the availability of the moderator heat removal. In the present paper, the moderator subcooling analysis is performed using the same methodology and assumptions except for RCW temperature used in FSAR Large LOCA PART F.

    Peimbert, Manuel; Peimbert, Antonio; Delgado-Inglada, Gloria


    We present a tutorial on the determination of the physical conditions and chemical abundances in gaseous nebulae. We also include a brief review of recent results on the study of gaseous nebulae, their relevance for the study of stellar evolution, galactic chemical evolution, and the evolution of the universe. One of the most important problems in abundance determinations is the existence of a discrepancy between the abundances determined with collisionally excited lines and those determined by recombination lines: this is called abundance discrepancy factor (ADF) problem, and we review results related to it. Finally, we discuss the possible reasons for the large t 2 values observed in gaseous nebulae.

  20. A detailed study of the supernova remnant RCW 86 in TeV {gamma}-rays

    Energy Technology Data Exchange (ETDEWEB)

    Heinz, Sebastian


    A detailed study of the supernova remnant RCW 86 is presented. RCW 86 encountered a shell-like structure in radio, X-rays and optical, whereas in the discovery paper of RCW 86 in the very high energy regime the structure could not be confirmed. In this thesis for the first time the shell was resolved in the very high energy gamma rays. The shell width was determined to be 0.125 {+-}0.014 , the radius to be 0.194 {+-} 0.016 and the center to be -62.433 {+-}0.014 in declination and 220.734 {+-}0.016 in rectascension. The spectral analysis was performed for the whole SNR and for the south-east part, which is more pronounced in X-rays separately. But the results were comparable within errors. Additionally a power-law with an exponential cut off described the spectra best with the parameters: an spectral index of 1.50{+-}0.28, a cut-off energy of (2.69{+-}0.99 TeV) and an integral flux above 1 TeV of (6.51{+-}2.69) . 10{sup -12} cm{sup -2}s{sup -1}. The study of the correlation of the X-ray and VHE {gamma}-ray data of RCW 86 was hampered by the poor angular resolution of the VHE data. Therefore detailed studies of the Richardson-Lucy deconvolution algorithm have been performed. The outcome is, that deconvolution techniques are applicable to strong VHE {gamma}-ray sources and that fine structure well below the angular resolution can be studied. The application to RX J1713-3946, the brightest SNR in the VHE regime, has shown, that the correlation coefficient of the X-ray data and the VHE data of is stable down to 0.01 and has a value of 0.85. On the other side the significance of the data set is not sufficient in the case of RCW 86 to apply the deconvolution technique.

  1. Biochemical characterization and functional complementation of ribonuclease HII and ribonuclease HIII from Chlamydophila pneumoniae AR39. (United States)

    Liang, Rubing; Liu, Xipeng; Pei, Dongli; Liu, Jianhua


    Chlamydophila pneumoniae AR39 contains two different ORFs (CP0654 and CP0782) encoding ribonuclease H (RNase H) homologues, Cpn-RNase HII and Cpn-RNase HIII. Sequence alignments show that the two homologues both contain the conserved motifs of type 2 RNase H, and Cpn-RNase HII has the conserved active-site motif (DEDD) of RNase HII. Cpn-RNase HIII also contains a unique active-site motif (DEDE), common to other RNase HIIIs. Complementation assays indicated that Cpn-RNase HII can complement both Escherichia coli RNase HII and RNase HI, but Cpn-RNase HIII can only complement the latter. In vitro enzyme activity experiments showed that neither Cpn-RNase HII nor Cpn-RNase HIII is thermostable and their optimum pH values were 9.0 and 10.0, respectively. Cpn-RNase HII cleaves a 12 bp RNA-DNA substrate at multiple sites, but Cpn-RNase HIII at only one site. When a 35 bp DNA-RNA-DNA/DNA chimeric substrate was used, cleavage was only observed with Cpn-RNase HII. These results indicate that the RNase H combination of C. pneumoniae AR39 is not simple substitution of E. coli RNase H, perhaps representing a more primordial type. This is believed to be the first in vivo functional study of Chlamydophila RNase Hs and the results should contribute to the analysis of RNase Hs of other parasite species.

    Gvaramadze, Vasilii V.; Langer, Norbert; Fossati, Luca; Bock, Douglas C.-J.; Castro, Norberto; Georgiev, Iskren Y.; Greiner, Jochen; Johnston, Simon; Rau, Arne; Tauris, Thomas M.


    When a massive star in a binary system explodes as a supernova, its companion star may be polluted with heavy elements from the supernova ejecta. Such pollution has been detected in a handful of post-supernova binaries 1 , but none of them is associated with a supernova remnant. We report the discovery of a binary G star strongly polluted with calcium and other elements at the position of the candidate neutron star [GV2003] N within the young galactic supernova remnant RCW 86. Our discovery suggests that the progenitor of the supernova that produced RCW 86 could have been a moving star, which exploded near the edge of its wind bubble and lost most of its initial mass because of common-envelope evolution shortly before core collapse, and that the supernova explosion might belong to the class of calcium-rich supernovae — faint and fast transients 2,3 , the origin of which is strongly debated 4-6 .

  4. The outflow history of two Herbig-Haro jets in RCW 36: HH 1042 and HH 1043 (United States)

    Ellerbroek, L. E.; Podio, L.; Kaper, L.; Sana, H.; Huppenkothen, D.; de Koter, A.; Monaco, L.


    Jets around low- and intermediate-mass young stellar objects (YSOs) contain a fossil record of the recent accretion and outflow activity of their parent star-forming systems. We aim to understand whether the accretion/ejection process is similar across the entire stellar mass range of the parent YSOs. To this end we have obtained optical to near-infrared spectra of HH 1042 and HH 1043, two newly discovered jets in the massive star-forming region RCW 36, using X-shooter on the ESO Very Large Telescope. HH 1042 is associated with the intermediate-mass YSO 08576nr292. Over 90 emission lines are detected in the spectra of both targets. High-velocity (up to 220 km s-1) blue- and redshifted emission from a bipolar flow is observed in typical shock tracers. Low-velocity emission from the background cloud is detected in nebular tracers, including lines from high ionization species. We applied combined optical and infrared spectral diagnostic tools in order to derive the physical conditions (density, temperature, and ionization) in the jets. The measured mass outflow rates are Ṁjet ~ 10-7M⊙ yr-1. It is not possible to determine a reliable estimate for the accretion rate of the driving source of HH 1043 using optical tracers. We measure a high accretion rate for the driving source of HH 1042 (Ṁacc ~ 10-6M⊙ yr-1). For this system the ratio Ṁjet/Ṁacc ~ 0.1, which is comparable to low-mass sources and consistent with models for magneto-centrifugal jet launching. The knotted structure and velocity spread in both jets are interpreted as fossil signatures of a variable outflow rate. While the mean velocities in both lobes of the jets are comparable, the variations in mass outflow rate and velocity in the two lobes are not symmetric. This asymmetry suggests that the launching mechanism on either side of the accretion disk is not synchronized. For the HH 1042 jet, we have constructed an interpretative physical model with a stochastic or periodic outflow rate and a

  5. Results from the Heavy Ions In Space (HIIS) experiment on the ionic charge state of solar energetic particles (United States)

    Tylka, Allan J.; Boberg, Paul R.; Adams, James H., Jr.; Beahm, Lorraine P.; Kleis, Thomas


    It has long been known that low-energy solar energetic particles (SEP's) are partially-ionized. For example, in large, so-called 'gradual' solar energetic particle events, at approximately 1 MeV/nucleon the measured mean ionic charge state, Q, of Fe ions is 14.1 +/- 0.2, corresponding to a plasma temperature of approximately 2 MK in the coronal or solar-wind source material. Recent studies, which have greatly clarified the origin of solar energetic particles and their relation to solar flares, suggest that ions in these SEP events are accelerated not at a flare site, but by shocks propagating through relatively low-density regions in the interplanetary medium. As a result, the partially-ionized states observed at low energies are expected to continue to higher energies. However, up to now there have been no high-energy measurements of ionic charge states to confirm this notion. We report here HIIS observations of Fe-group ions at 50-600 MeV/nucleon, at energies and fluences which cannot be explained by fully-ionized galactic cosmic rays, even in the presence of severe geomagnetic cutoff suppression. Above approximately 200 MeV/nucleon, all features of our data -- fluence, energy spectrum, elemental composition, and arrival directions -- can be explained by the large SEP events of October 1989, provided that the mean ionic charge state at these high energies is comparable to the measured value at approximately 1 MeV/nucleon. By comparing the HIIS observations with measurements in interplanetary space in October 1989, we determine the mean ionic charge state of SEP Fe ions at approximately 200-600 MeV/nucleon to be Q = 13.4 plus or minus 1.0, in good agreement with the observed value at approximately 1 MeV/nucleon. The source of the ions below approximately 200 MeV/nucleon is not yet clear. Partially-ionized ions are less effectively deflected by the Earth's magnetic field than fully-ionized cosmic rays and therefore have greatly enhanced access to low-Earth orbit

  6. Condições físicas em galáxias HII (United States)

    Kehrig, C.; Telles, E.; Cuisinier, F.


    Galáxias HII são galáxias anãs de baixa luminosidade que apresentam alta taxa de formação estelar. Seus espectros são dominados por intensas linhas de emissão devido à fotoionização pela presença de um grande número de estrelas do tipo O e B. Nós apresentamos um catálogo espectrofotométrico de 111 galáxias HII observadas no telescópio 1.52m do ESO com o espectrógrafo Boller & Chivens. Determinamos propriedades estatísticas da amostra e derivamos condições físicas (temperatura eletrônica, densidade eletrônica) e abundâncias químicas. Para algumas galáxias, fomos também capazes de resolver espacialmente regiões de formação estelar individuais e determinar propriedades espectroscópicas para estas regiões separadamente, o que nos permitiu avaliar as flutuações das condições físico-químicas dentro das galáxias HII. Em particular, vimos que apesar das galáxias HII apresentarem formação estelar espalhada ao longo do corpo da galáxia, são objetos quimicamente homogêneos. A fim de estudar a evolução temporal dos objetos durante o tempo de vida das estrelas ionizantes construimos também alguns diagramas relacionando razões de linhas de emissão com a largura equivalente de Hb (EW(Hb)). Para interpretar tais diagramas utilizamos modelos de fotoionização para populações estelares integradas. Concluímos que as galáxias HII não correspondem a simples idéia de um burst instantâneo envolvido por um gás opaco aos fótons ionizantes e com densidade constante. As relações observadas entre razões de linhas e EW(Hb) podem ser melhor compreendidas se as galáxias HII apresentarem populações estelares mais velhas, que contribuem para o contínuo óptico observado.

    Analisamos o conteúdo estelar de 74 galáxias HII a partir do contínuo observado nos espectros ópticos dessas galáxias, utilizando métodos de síntese de população estelar. Descobrimos que todas as galáxias para as quais encontramos soluções contêm uma população estelar velha que domina a massa estelar, e numa maioria dessas também encontramos evidência de uma população de idade intermediaria além da geração jovem que está se formando agora. Concluímos que a formação estelar dessas galáxias se realiza em surtos individuais, Esses surtos são interrompidos por longos períodos de inatividade, com os primeiros consumindo a maior parte do gás. Sugerimos, portanto, que as galáxias HII sejam galáxias anãs normais flagradas em um período de surto.

  9. The rnhB gene encoding RNase HII of Streptococcus pneumoniae and evidence of conserved motifs in eucaryotic genes. (United States)

    Zhang, Y B; Ayalew, S; Lacks, S A


    A single RNase H enzyme was detected in extracts of Streptococcus pneumoniae. The gene encoding this enzyme was cloned and expressed in Escherichia coli, as demonstrated by its ability to complement a double-mutant rnhA recC strain. Sequence analysis of the cloned DNA revealed an open reading frame of 290 codons that encodes a polypeptide of 31.9 kDa. The predicted protein exhibits a low level of homology (19% identity of amino acid residues) to RNase HII encoded by rnhB of E. coli. Identification of the S. pneumoniae RNase HII translation start site by amino-terminal sequencing of the protein and of mRNA start sites by primer extension with reverse transcriptase showed that the major transcript encoding rnhB begins at the protein start site. Comparison of the S. pneumoniae and E. coli RNase HII sequences and sequences of other, putative bacterial rnhB gene products surmised from sequencing data revealed three conserved motifs. Use of these motifs to search for homologous genes in eucaryotes demonstrated the presence of rnhB genes in a yeast and a roundworm. Partial rnhB gene sequences were detected among expressed sequences of mouse and human cells. From these data, it appears that RNase HII is universally present in living cells.

    The objective of the H-II Orbiting Plane-Experimental(HOPE-X) project is to develop the major technologies necessary for two-way space transportation systems on the bases of precursor elemental flight experiments such as OREX, HYFLEX and ALFLEX and to demonstrate them through the flight experiment of an operational size vehicle. At present, the HOPE-X project is in the development phase and various efforts for system design and fundamental technologies are being conducted through the co-operational works between the National Aerospace Laboratory (NAL) and the National Space Development Agency of Japan (NASDA). Moreover the plan to improve the HOPE-X vehicle after the flight experiment and to use it for practical missions is investigated.

    The star HII 2407 is a member of the relatively young Pleiades star cluster and was previously discovered to be a single-lined spectroscopic binary. It is newly identified here within Kepler/K2 photometric time series data as an eclipsing binary system. Mutual fitting of the radial velocity and photometric data leads to an orbital solution and constraints on fundamental stellar parameters. While the primary has arrived on the main sequence, the secondary is still pre-main sequence and we compare our results for the M/M{sub ⊙} and R/R{sub ⊙} values with stellar evolutionary models. We also demonstrate that the system is likely to be tidally synchronized. Follow-up infrared spectroscopy is likely to reveal the lines of the secondary, allowing for dynamically measured masses and elevating the system to benchmark eclipsing binary status.

  12. Perfis de temperatura eletrônica em regiões HII (United States)

    Copetti, M. V. F.


    As flutuações de temperatura eletrônica em regiões HII, inicialmente propostas para explicar as discrepâncias entre os valores de temperatura obtidos por diferentes métodos, têm sido apontadas como a causa mais provável das enormes diferenças encontradas entre as abundâncias químicas medidas através de linhas excitadas colisionalmente e de linhas de recombinação. Recentemente têm sido reportadas tentativas de detecção e quantificação diretas das flutuações de temperatura eletrônica através de medidas ponto a ponto, obtidas por meio de espectroscopia de fenda longa, das razões de linhas [OIII]l4263/l5007 e [NII]l5755/l6584, principais sensores de temperatura. Neste trabalho, utilizamos o código numérico de fotoionização Cloudy para avaliar a confiabilidade desse procedimento. Concluímos que, para valores de densidade eletrônica e de temperatura efetiva da estrela ionizante típicos das regiões HII, os perfis superficiais de temperatura obtidos via medidas do sensor [OIII]l4263/l5007 são bons traçadores dos gradientes internos de temperatura eletrônica. Já os perfis de temperatura eletrônica medidos por meio da razão [NII]l5755/l6584 não reproduzem os gradientes verdadeiros de temperatura.

    We present distributions of two molecular clouds having velocities of 2 and 14 km s{sup −1} toward RCW 38, the youngest super star cluster in the Milky Way, in the {sup 12}CO J = 1–0 and 3–2 and {sup 13}CO J = 1–0 transitions. The two clouds are likely physically associated with the cluster as verified by the high intensity ratio of the J = 3–2 emission to the J = 1–0 emission, the bridging feature connecting the two clouds in velocity, and their morphological correspondence with the infrared dust emission. The velocity difference is too large for the clouds to be gravitationally bound. We frame a hypothesis that the two clouds are colliding with each other by chance to trigger formation of the ∼20 O stars that are localized within ∼0.5 pc of the cluster center in the 2 km s{sup −1} cloud. We suggest that the collision is currently continuing toward part of the 2 km s{sup −1} cloud where the bridging feature is localized. This is the third super star cluster alongside Westerlund 2 and NGC 3603 where cloud–cloud collision has triggered the cluster formation. RCW 38 is the youngest super star cluster in the Milky Way, holding a possible sign of on-going O star formation, and is a promising site where we may be able to witness the moment of O star formation.

  15. MS_RHII-RSD, a dual-function RNase HII-(p)ppGpp synthetase from Mycobacterium smegmatis. (United States)

    Murdeshwar, Maya S; Chatterji, Dipankar


    In the noninfectious soil saprophyte Mycobacterium smegmatis, intracellular levels of the stress alarmones guanosine tetraphosphate and guanosine pentaphosphate, together termed (p)ppGpp, are regulated by the enzyme Rel(Msm). This enzyme consists of a single, bifunctional polypeptide chain that is capable of both synthesizing and hydrolyzing (p)ppGpp. The rel(Msm) knockout strain of M. smegmatis (Δrel(Msm)) is expected to show a (p)ppGpp null [(p)ppGpp(0)] phenotype. Contrary to this expectation, the strain is capable of synthesizing (p)ppGpp in vivo. In this study, we identify and functionally characterize the open reading frame (ORF), MSMEG_5849, that encodes a second functional (p)ppGpp synthetase in M. smegmatis. In addition to (p)ppGpp synthesis, the 567-amino-acid-long protein encoded by this gene is capable of hydrolyzing RNA·DNA hybrids and bears similarity to the conventional RNase HII enzymes. We have classified this protein as actRel(Msm) in accordance with the recent nomenclature proposed and have named it MS_RHII-RSD, indicating the two enzymatic activities present [RHII, RNase HII domain, originally identified as domain of unknown function 429 (DUF429), and RSD, RelA_SpoT nucleotidyl transferase domain, the SYNTH domain responsible for (p)ppGpp synthesis activity]. MS_RHII-RSD is expressed and is constitutively active in vivo and behaves like a monofunctional (p)ppGpp synthetase in vitro. The occurrence of the RNase HII and (p)ppGpp synthetase domains together on the same polypeptide chain is suggestive of an in vivo role for this novel protein as a link connecting the essential life processes of DNA replication, repair, and transcription to the highly conserved stress survival pathway, the stringent response.

  16. Probing the Galactic Structure of the Milky Way with H II Regions (United States)

    Red, Wesley Alexander; Wenger, Trey V.; Balser, Dana; Anderson, Loren; Bania, Thomas


    Mapping the structure of the Milky Way is challenging since we reside within the Galactic disk and distances are difficult to determine. Elemental abundances provide important constraints on theories of the formation and evolution of the Milky Way. HII regions are the brightest objects in the Galaxy at radio wavelengths and are detected across the entire Galactic disk. We use the Jansky Very Large Array (VLA) to observe the radio recombination line (RRL) and continuum emission of 120 Galactic HII regions located across the Galactic disk. In thermal equilibrium, metal abundances are expected to set the nebular electron temperature with high abundances producing low temperatures. We derive the metallicity of HII regions using an empirical relation between an HII region's radio recombination line-to-continuum ratio and nebular metallicity. Here we focus on a subset of 20 HII regions from our sample that have been well studied with the Green Bank Telescope (GBT) to test our data reduction pipeline and analysis methods. Our goal is to expand this study to the Southern skies with the Australia Telescope Compact Array and create a metallicity map of the entire Galactic disk.

  18. Interstellar gas and X-rays toward the Young supernova remnant RCW 86; pursuit of the origin of the thermal and non-thermal X-ray (United States)

    Sano, H.; Reynoso, E. M.; Mitsuishi, I.; Nakamura, K.; Furukawa, N.; Mruganka, K.; Fukuda, T.; Yoshiike, S.; Nishimura, A.; Ohama, A.; Torii, K.; Kuwahara, T.; Okuda, T.; Yamamoto, H.; Tachihara, K.; Fukui, Y.


    We have analyzed the atomic and molecular gas using the 21 cm HI and 2.6/1.3 mm CO emissions toward the young supernova remnant (SNR) RCW 86 in order to identify the interstellar medium with which the shock waves of the SNR interact. We have found an HI intensity depression in the velocity range between -46 and - 28 kms-1 toward the SNR, suggesting a cavity in the interstellar medium. The HI cavity coincides with the thermal and non-thermal emitting X-ray shell. The thermal X-rays are coincident with the edge of the HI distribution, which indicates a strong density gradient, while the non-thermal X-rays are found toward the less dense, inner part of the HI cavity. The most significant non-thermal X-rays are seen toward the southwestern part of the shell where the HI gas traces the dense and cold component. We also identified CO clouds which are likely interacting with the SNR shock waves in the same velocity range as the HI, although the CO clouds are distributed only in a limited part of the SNR shell. The most massive cloud is located in the southeastern part of the shell, showing detailed correspondence with the thermal X-rays. These CO clouds show an enhanced CO J = 2- 1 / 1- 0 intensity ratio, suggesting heating/compression by the shock front. We interpret that the shock-cloud interaction enhances non-thermal X-rays in the southwest and the thermal X-rays are emitted by the shock-heated gas of density 10-100 cm-3. Moreover, we can clearly see an HI envelope around the CO cloud, suggesting that the progenitor had a weaker wind than the massive progenitor of the core-collapse SNR RX J1713.7-3949. It seems likely that the progenitor of RCW 86 was a system consisting of a white dwarf and a low-mass star with low-velocity accretion winds.

    Full Text Available The fermented herbal juices are capable of curing and preventing diseases and reducing the aging progress. The present study was performed to investigate the fermentation of Phyllanthus emblica fruit by Lactobacillus paracasei HII01 with respect to carbon sources, polyphenols, and antioxidant properties. The physical changes, for instance, color, odor, taste, turbidity and gas formation, throughout the fermentation process was manually monitored. The fermented product was rich in polyphenolic content. The acid content and pH of the product were under the norms of Thai community product standards. Antioxidant properties of the fermented product were proved using ABTS, and FRAP assays. Chelation based study suggested that fermented P. emblica fruit juices are healthy enough to stabilize the oxidized form of the metal ion. The optimum fermentation period was 15 days. All the results supported that studied carbon sources did not interfere with the quality of the product. This report is the prelude study on the use of probiotic starter culture for the production of P. emblica fruit based lactic acid bacteria fermented beverages (LAFB enriched with bioactive compounds. Further research on the impact of different carbon sources and upstream processes on the quality of LAFB is currently in progress.

  20. Evaluation of regional work from ECG-gated SPECT images through solution of equations of continuity for fluids-mechanical cardiac work calculated using thin wall model. (United States)

    Maeda, Hisatoshi


    Regional contraction work (RCW) of left ventricle (LV) was evaluated from cardiac perfusion images of ECG-gated single photon emission computed tomography (ECG-SPECT). The mechanical work was computed as a product of force and displaced distance. Force was determined from Laplace's law under a rectangle pressure. Deformation of wireframe representing LV was calculated from equations of continuity for two-dimensional fluids. Experiments were performed with homemade life-sized cardiac models. Total contraction work (TCW) and stroke work (SW) were 524.0 ± 166.1 mJ/beat and 709.8 ± 169.5 mJ/beat, respectively, in normal subjects (n = 23). Moderate correlation was seen between TCW and SW (y = -43.4 + 0.779 x, r = 0.815). The regional contraction amplitude (RCA), synchronous contraction index and RCW were 35.4 ± 3.5%, 95.4 ± 3.1% and 5.58 ± 0.97 mJ cm(-2)/beat in normal subjects, whereas those in patients with decreased ejection raction (EF) ≤ 30% (n = 6) were 19.6 ± 7.7%, 64.4 ± 32.2% and 2.58 ± 0.82 mJ cm(-2)/beat (p < 0.0001, Student's t-test). There was a poor correlation between RCW and RCA (y = 1.648 ± 0.116 x, r = 0.501) in normal subjects, suggesting that it might not be suitable to use RCA as an alternative to evaluate RCW.

  1. Synaptic elements for GABAergic feed-forward signaling between HII horizontal cells and blue cone bipolar cells are enriched beneath primate S-cones. (United States)

    Puller, Christian; Haverkamp, Silke; Neitz, Maureen; Neitz, Jay


    The functional roles and synaptic features of horizontal cells in the mammalian retina are still controversial. Evidence exists for feedback signaling from horizontal cells to cones and feed-forward signaling from horizontal cells to bipolar cells, but the details of the latter remain elusive. Here, immunohistochemistry and confocal microscopy were used to analyze the expression patterns of the SNARE protein syntaxin-4, the GABA receptor subunits α1 and ρ, and the cation-chloride cotransporters NKCC and KCC2 in the outer plexiform layer of primate retina. In macaque retina, as observed previously in other species, syntaxin-4 was expressed on dendrites and axon terminals of horizontal cells at cone pedicles and rod spherules. At cones, syntaxin-4 appeared densely clustered in two bands, at horizontal cell dendritic tips and at the level of desmosome-like junctions. Interestingly, in the lower band where horizontal cells may synapse directly onto bipolar cells, syntaxin-4 was highly enriched beneath short-wavelength sensitive (S) cones and colocalized with calbindin, a marker for HII horizontal cells. The enrichment at S-cones was not observed in either mouse or ground squirrel. Furthermore, high amounts of both GABA receptor and cation-chloride cotransporter subunits were found beneath primate S-cones. Finally, while syntaxin-4 was expressed by both HI and HII horizontal cell types, the intense clustering and colocalization with calbindin at S-cones indicated an enhanced expression in HII cells. Taken together, GABA receptors beneath cone pedicles, chloride transporters, and syntaxin-4 are putative constituents of a synaptic set of proteins which would be required for a GABA-mediated feed-forward pathway via horizontal cells carrying signals directly from cones to bipolar cells.

  2. Unit cell structure of water-filled monoolein into inverted hexagonal (H(II)) mesophase modeled by molecular dynamics. (United States)

    Kolev, Vesselin L; Ivanova, Anela N; Madjarova, Galia K; Aserin, Abraham; Garti, Nissim


    The study investigates the unit cell structure of inverted hexagonal (H(II)) mesophase composed of monoolein (1-monoolein, GMO) and water using atomistic molecular dynamics methods without imposing any restraints on lipid and water molecules. Statistically meaningful and very contrast images of the radial mass density distribution, scrutinizing also the separate components water, monoolein, the polar headgroups of the lipids, the double bond, and the termini of the hydrocarbon chain (the tail), are obtained. The lipid/water interface structure is analyzed based on the obtained water density distribution, on the estimated number of hydrogen bonds per monoolein headgroup, and on the headgroup-water radial distribution functions. The headgroup mass density distribution demonstrates hexagonal shape of the monoolein/water interface that is well-defined at higher water/monoolein ratios. Water interacts with the headgroups by forming a three-layer diffusive mass density distribution, and each layer's shape is close to hexagonal, which is an indication of long-range structural interactions. It is found that the monoolein headgroups form a constant number of hydrogen bonds leaving an excessive amount of water molecules outside the first lipid coordination sphere. Furthermore, the quantity of water at the monoolein/water interface increases steadily upon extension of the unit cell, so the interface should have a very dynamic structure. Investigation of the hydrocarbon residues reveals high compression and well-expressed structuring of the tails. The tails form a very compressed and constrained structure of defined layers across the unit cell with properties corresponding to a more densely packed nonpolar liquid (oil). Due to the hexagonal shape the 2D packing frustration is constant and does not depend on the water content. All reported structural features are based on averaging of the atomic coordinates over the time-length of the simulation trajectories. That kind of

    Harvey, P.M.; Wilking, B.A.; Joy, M.; Lester, D.F.


    Infrared observations from 1 to 100 microns are presented for the region associated with a bipolar CO outflow source near the nebulous objects GGD 12 to 15. A luminous far-infrared source was found associated with a radio-continuum source in the area. This object appears to be a compact HII region around a nearly main-sequence BO star. A faint 20 micron source was also discovered at the position of an H2O maser 3O deg northwest of the HII region. This object appears to be associated with but not coincident with a 2 micron reflection nebula. This structure serves as evidence for a non-spherically symmetric, possibly disk-like dust distribution around the exciting star for the maser. This object probably powers the bi-polar CO outflow although its luminosity is less than 10% that of the star which excites the compact HII region. A number of other 2 micron sources found in the area are probably members of a recently formed cluster.

  6. Wind bubbles within H ii regions around slowly moving stars (United States)

    Mackey, Jonathan; Gvaramadze, Vasilii V.; Mohamed, Shazrene; Langer, Norbert


    Interstellar bubbles around O stars are driven by a combination of the star's wind and ionizing radiation output. The wind contribution is uncertain because the boundary between the wind and interstellar medium is difficult to observe. Mid-infrared observations (e.g., of the H ii region RCW 120) show arcs of dust emission around O stars, contained well within the H ii region bubble. These arcs could indicate the edge of an asymmetric stellar wind bubble, distorted by density gradients and/or stellar motion. We present two-dimensional, radiation-hydrodynamics simulations investigating the evolution of wind bubbles and H ii regions around massive stars moving through a dense (nH = 3000 cm-3), uniform medium with velocities ranging from 4 to 16 km s-1. The H ii region morphology is strongly affected by stellar motion, as expected, but the wind bubble is also very aspherical from birth, even for the lowest space velocity considered. Wind bubbles do not fill their H ii regions (we find filling factors of 10-20 per cent), at least for a main sequence star with mass M⋆ ~ 30 M⊙. Furthermore, even for supersonic velocities the wind bow shock does not significantly trap the ionization front. X-ray emission from the wind bubble is soft, faint, and comes mainly from the turbulent mixing layer between the wind bubble and the H ii region. The wind bubble radiates Movies are available in electronic form at

  7. Hubble Space Telescope Hx Imaging of Star-forming Galaxies at z approximately equal to 1-1.5: Evolution in the Size and Luminosity of Giant H II Regions (United States)

    Livermore, R. C.; Jones, T.; Richard, J.; Bower, R. G.; Ellis, R. S.; Swinbank, A. M.; Rigby, J. R.; Smail, Ian; Arribas, S.; Rodriguez-Zaurin, J.; hide


    We present Hubble Space Telescope/Wide Field Camera 3 narrow-band imaging of the Ha emission in a sample of eight gravitationally lensed galaxies at z = 1-1.5. The magnification caused by the foreground clusters enables us to obtain a median source plane spatial resolution of 360 pc, as well as providing magnifications in flux ranging from approximately 10× to approximately 50×. This enables us to identify resolved star-forming HII regions at this epoch and therefore study their Ha luminosity distributions for comparisons with equivalent samples at z approximately 2 and in the local Universe. We find evolution in the both luminosity and surface brightness of HII regions with redshift. The distribution of clump properties can be quantified with an HII region luminosity function, which can be fit by a power law with an exponential break at some cut-off, and we find that the cut-off evolves with redshift. We therefore conclude that 'clumpy' galaxies are seen at high redshift because of the evolution of the cut-off mass; the galaxies themselves follow similar scaling relations to those at z = 0, but their HII regions are larger and brighter and thus appear as clumps which dominate the morphology of the galaxy. A simple theoretical argument based on gas collapsing on scales of the Jeans mass in a marginally unstable disc shows that the clumpy morphologies of high-z galaxies are driven by the competing effects of higher gas fractions causing perturbations on larger scales, partially compensated by higher epicyclic frequencies which stabilize the disc.

  8. Carbon Monoxide Observations Toward Star Forming Regions in the Outer Scutum-CentaurusSpiral Arm (United States)

    Ferraro, Nicholas; Wenger, Trey V.; Khan, Asad; Balser, Dana; Armentrout, William Paul; Anderson, Loren Dean; Bania, Thomas


    The Outer Scutum-Centaurus arm (OSC) is the most distant molecular spiral arm known in the Milky Way. The Scutum-Centaurus spiral arm is posited to start at the end of the Galactic bar and to extend beyond the Solar orbit into the outer Galaxy. Carbon monoxide (CO) emission from molecular clouds is a bright star formation tracer that was recently discovered in the OSC in the first Galactic quadrant and may extend into the second quadrant. The population of star formation tracers in the OSC remains largely uncharacterized in part because the arm is distant enough from the Galactic Center to be affected by the Galactic warp. The OSC rises above the Galactic plane by nearly 4 degrees in the first quadrant, meaning most in-plane surveys of molecular gas or star formation tracers have missed the arm previously. Here we use the Arizona Radio Observatory (ARO) 12m telescope to observe 12CO J = 1-0 and 13CO J = 1-0 transitions toward 158 HII region candidates in the first and second Galactic quadrants chosen from the WISE Catalog of Galactic HII Regions. These targets are spatially coincident with the Galactic longitude-latitude (l, b) OSC locus as defined by HI emission. We detect CO toward most of our targets, many of which have at least one emission line originating beyond the Solar orbit. We compare the physical properties of molecular clouds in the OSC to the physical properties of molecular clouds located elsewhere in the Galaxy.

  10. Distribution of water in the G327.3-0.6 massive star-forming region (United States)

    Leurini, S.; Herpin, F.; van der Tak, F.; Wyrowski, F.; Herczeg, G. J.; van Dishoeck, E. F.


    Aims: Following our past study of the distribution of warm gas in the G327.3-0.6 massive star-forming region, we aim here at characterizing the large-scale distribution of water in this active region of massive star formation made of individual objects in different evolutionary phases. We investigate possible variations of the water abundance as a function of evolution. Methods: We present Herschel/PACS (4'× 4') continuum maps at 89 and179 μm encompassing the whole region (Hii region and the infrared dark cloud, IRDC) and an APEX/SABOCA (2'× 2') map at 350 μm of the IRDC. New spectral Herschel/HIFI maps toward the IRDC region covering the low-energy water lines at 987 and 1113 GHz (and their H218O counterparts) are also presented and combined with HIFI pointed observations toward the G327 hot core region. We infer the physical properties of the gas through optical depth analysis and radiative transfer modeling of the HIFI lines. Results: The distribution of the continuum emission at 89 and 179 μm follows the thermal continuum emission observed at longer wavelengths, with a peak at the position of the hot core and a secondary peak in the Hii region, and an arch-like layer of hot gas west of this Hii region. The same morphology is observed in the p-H2O 111-000 line, in absorption toward all submillimeter dust condensations. Optical depths of approximately 80 and 15 are estimated and correspond to column densities of 1015 and 2 × 1014 cm-2, respectively, for the hot core and IRDC position. These values indicate an abundance of water relative to H2 of 3 × 10-8 toward the hot core, while the abundance of water does not change along the IRDC with values close to some 10-8. Infall (over at least 20″) is detected toward the hot core position with a rate of 1-1.3 × 10-2M⊙ /yr, high enough to overcome the radiation pressure that is due to the stellar luminosity. The source structure of the hot core region appears complex, with a cold outer gas envelope in

    El ancho equivalente WHβ de la linea de Hβ en emisión y la razón [0 III]/Hβ del par λλ4959, 50 7 A del [0111], fueron medidos en 23 regiones HII de la Peque˜a Nube de Magallanes, por medio de la fotometría fotoeléctrica a través de un sistema de tres filtros interferenciales: dos Hβ , con bandas pasantes de 100 y 30 A, y un [0111] centrado en 5000 A y con banda pasante de 50 A. Las observaciones fueron realizadas con los telescopios de 1.60-m y 0.60-m del Laboratorio Nacional de Astrofísica, Brasópolis, Brasil. Fueron escogidos diafragmas suficientemente grandes para captar la radiación integrada de cada región HII. Las medidas fueron calibradas por comparación a un conjunto de nebulosas planetarias con flujos absolutos bien definidos. A través de la comparación entre los datos observacionales y modelos evolutivos de WHβ y [0 III] /Hβ (Copetti et al.1986', Astr. and Ap., 156, 111), las edades de las regiones HIl fueron estimadas. Basada en la distribución espacial de las edades de regiones HIl, la historia de la formación estelar reciente en la Pequeña Nube de Magallanes es analizada. La similitud de las medidas de WH&beta y [OIII]/WHβ entre las regiones H II observadas sugiere que hubo una explosión de formación estelar a 4±1 x106 años en la Pequeña Nube de Magallanes.

  13. Kinematics of the active region of the quasar 3C 345 (United States)

    Matveyenko, L. I.; Sivakon', S. S.


    The fine structure of the quasar 3C 345 in polarized emission at 7 mm and 2 cm has been investigated. The kinematics is shown to correspond to an anticentrifuge: the thermal plasma of the surrounding space accretes onto the disk, flows to the center, and is ejected in the form of a rotating bipolar outflow that carries away the excess angular momentum as it accumulates. The bipolar outflow consists of a high-velocity central jet surrounded by a low-velocity component. The low-velocity flows are the rotating hollow tubes ejected from the peripheral part of the disk with a diameter ˜Ø1 = 2.2 pc and from the region Ø2 = 1 pc. The high-velocity jet with a diameter Ø3 = 0.2 pc is ejected from the central part of the disk, while the remnant falls onto the forming central body. The ejection velocity of the high-velocity flow is v ⩾ 0.06 c. At a distance up to ˜1 pc, the jet accelerates to an apparent velocity v ˜ 8 c. Further out, uniform motion is observed within ˜2 pc following which deceleration occurs. The jet structure corresponding to a conical diverging helix with an increasing pitch is determined by gasdynamic instability. The counterjet structure is a mirror reflection of the nearby part of the jet. The brightness temperature of the fragment of the high-velocity flow at the exit from the counterjet nozzle is T b ≈ (1012-1013) K. The disk inclined at an angle of 60° to the plane of the sky shadows the jet ejector region. Ring currents observed in the tangential directions as parallel chains of components are excited in the rotating flows. The magnetic fields of the rotating bipolar outflow and the disk are aligned and oriented along the rotation axis. The translational motions of the jet and counterjet are parallel and antiparallel to the magnetic field, which determines their acceleration or deceleration. The quasar core is surrounded by a thermal plasma. The sizes of the HII region reach ˜30 pc. The electron density decreases with increasing

  14. VLA Observations of Flux Density Variations at 3.6 cm in the Massive Star Forming Region W49A (United States)

    In recent years, a number of ultracompact Galactic star forming regions have been detected to vary in flux density on short timescales ($\\sim$10-20 years). This variation can result when ionizing stars, orbiting within the filamentary structures formed in a gravitationally collapsing cloud, enter or leave a dense filament. The increase or decrease in the recombination rate from the change of density causes the H II region surrounding the star to shrink or grow. Here we focus on the massive star-forming region W49A, which was observed with the Karl G. Jansky Very Large Array (VLA) at 3.6 cm with the B-configuration in February 2015. These high resolution ($\\sim$0.8$\\arcsec$) observations were compared with B-configuration observations of the same region made with the VLA in August 1994, almost 21 years earlier. As expected, most of the sources in the crowded field of ultracompact (UC) and hypercompact (HC) HII regions exhibit no significant changes over this time period. One source, however, W49A/G2 has decreased by $\\sim$40\\% in peak intensity, from 202$\\pm$10 mJy/beam to 124$\\pm$10 mJy/beam. We present the 1994 and 2015 images of the W49A region, the difference images that indicate the position of the flux density decrease, and discuss possible explanations of the detected decrease near the position of W49A/G2.

    We present a comprehensive statistical analysis of star-forming objects located in the vicinities of 1360 bubble structures throughout the Galactic plane and their local environments. The compilation of 70 000 star-forming sources, found in the proximity of the ionized (Hii) regions and detected in both Hi-GAL and GLIMPSE surveys, provided a broad overview of the different evolutionary stages of star-formation in bubbles, from prestellar objects to more evolved young stellar objects (YSOs). Surface density maps of star-forming objects clearly reveal an evolutionary trend where more evolved star-forming objects (Class II YSO candidates) are found spatially located near the center, while younger star-forming objects are found at the edge of the bubbles. We derived dynamic ages for a subsample of 182 H II regions for which kinematic distances and radio continuum flux measurements were available. We detect approximately 80% more star-forming sources per unit area in the direction of bubbles than in the surrounding fields. We estimate the clump formation efficiency (CFE) of Hi-GAL clumps in the direction of the shell of the bubbles to be 15%, around twice the value of the CFE in fields that are not affected by feedback effects. We find that the higher values of CFE are mostly due to the higher CFE of protostellar clumps, in particular in younger bubbles, whose density of the bubble shells is higher. We argue that the formation rate from prestellar to protostellar phase is probably higher during the early stages of the (H II ) bubble expansion. Furthermore, we also find a higher fraction of massive YSOs (MYSOs) in bubbles at the early stages of expansion (simulations. Approximately 23% of the Hi-GAL clumps are found located in the direction of a bubble, with 15% for prestellar clumps and 41% for protostellar clumps. We argue that the high fraction of protostellar clumps may be due to the acceleration of the star-formation process cause by the feedback of the (Hii

  16. Molecular Outflows in Massive Star Forming Regions (United States)

    Cunningham, Nichol


    This thesis presents millimetre continuum and molecular line observations exploring the properties of molecular outflows towards massive star forming regions. Massive stars produce some of the most energetic phenomena in the Galaxy, yet we still do not have a comprehensive understanding of how they actually form. Outflows are known to play a key role in this formation process and their properties, particularly how they change depending on the mass, luminosity and evolution of the driving source can shed light on how massive stars actually form. This thesis presents observations at both high (SMA 3 arcsecond) and low (JCMT 15 arcsecond) spatial resolution of the known jet/outflow tracers, SiO and 12CO, towards a sample massive star forming region drawn from the RMS survey. Furthermore, the presence of infall signatures is explored through observations of HCO+ and H13CO+, and the hot core nature of the regions is probed using tracers such as CH3CN, HC3N and CH3OH. SiO is detected towards approximately 50% of the massive young stellar objects and HII regions in the JCMT sample. The detection of SiO appears to be linked to the age of the RMS source, with the likely younger sources showing a stronger dependence with SiO. The presence of SiO also appears to be linked to the CO velocity, with SiO more efficiently tracing sources with higher velocity dispersions. In the MOPRA observations towards a sample of 33 RMS sources, CH3CN is detected towards 66% of the sources, with the redder likely younger sources having the largest rotational temperatures. This thesis presents the first interferometric SiO (5-4) and 12CO (2-1) observations, taken with the SMA, towards the massive star forming region G203.3166/NGC 2264-C. In this intermediate/massive star forming cluster, SiO is again tracing the youngest sources. Both the SiO and 12CO emission trace two bipolar, high velocity outflows towards the mm brightest, IR-dark, likely youngest sources in this reg! ion. In contrast the IR

    Full Text Available Abstract: The article examines theoretical aspects of regional dimension in international relations and the ways to apply in practice the results of world politics’ analysis from the viewpoint of regional and macro-regional levels. It also considers the key discussion points on regions and macro-regions in the world and Russian research literature. The author concludes that this is exactly the new IR concepts of regional level which should become the prototype of original Russian regional and country studies. These studies need to have a higher degree of theoretical conceptualization of regional level as their basis. Such an approach will enable the researchers to draw deep and unconventional conclusions of practical use especially as far as the non-Western parts of the world which are traditionally less examined by Western researchers, theorists and practitioners are concerned.

    Directory of Open Access Journals (Sweden)



    Full Text Available A short etymological interpretation of the notion of regions (Rette Lineatte, etc.. The region is: R= f (S+P, where S is space and P is power. There follows an evaluation of the characteristics of the region and the presentation of different approaches to the region. From the classic ideas (von Humboldt, 1885, Dokuceaev, 1899, Herbertson, 1905, and others we get to a wide interpretative array of what we accept as organizational spatial units of geographical reality. The environmental region has important connotations with regard to the system as a surrounded element (man, society and the adjacent system. Critical environmental regions are areas where there already exists interactive degradation. The critical character may be physical, hence the “geocritical regions” or the result of human impact, hence the “anthropocritical regions.” Critical situations are differentiated at the local, regional, and global level. In order to understand critical regional situations we must refer to the following characteristics: fragility, resilience, and vulnerability. Still there are few environmental studies on critical regions and work must be done in this field.

The basic tasks of tourism development in the region, aimed at the formation and protection of the tourism-recreational sector, market of competitive services, attraction of maximum number of tourists to the region, etc. have been cleared out. The attention is focused on the main tourist potential of Khmelnytskyi region, including National Nature Park «Podilski Tovtry», National historical-cultural nature reserve «Kamianets», «Samchyky», Medzhybizh regional historical-ethnographic museum-fortress, sanatorium-resort facilities based on mineral waters and others. The attention is paid to the increase in income from tourism. Traditional hospitality of the population of the region, especially in rural areas, provides the possibility to combine tourists’ accommodation with the study of rural customs and traditions directly in the villages. Tourism in Khmelnytskyi region will be attractive to all tourists who want to eat healthy food, to stay outdoors and enjoy the beauty of the region. Also the article tells us about the development of other directions and familiarizes tourists with other enticements of Khmelnytskyi region using the positive brand of Kamianets-Podilskyi.

    This article reviews the past 15 years of developments in regional ocean data assimilation. A variety of scientific, management, and safety-related objectives motivate marine scientists to characterize many ocean environments, including coastal regions. As in weather prediction, the accurate representation of physical, chemical, and/or biological properties in the ocean is challenging. Models and observations alone provide imperfect representations of the ocean state, but together they can offer improved estimates. Variational and sequential methods are among the most widely used in regional ocean systems, and there have been exciting recent advances in ensemble and four-dimensional variational approaches. These techniques are increasingly being tested and adapted for biogeochemical applications.

  2. Promoting regional mobility

    DEFF Research Database (Denmark)

    Jensen, Anne

    Pricing of transport has been part of EU's common transport policy since this gained momentum in the early 1990s. Since then, it has been closely connected to the trans-European transport network (TEN-T) and to rising demands of efficient mobility systems at a local, regional and Community scale....... Development of pricing policies is contested at Community level and has taken place in a clash between different policy rationalities. Significantly though, the effects of the pricing policies are closely related to regional mobility systems, e.g. through financing large trans-border infrastructure projects...... and establishing common technical charging systems thus changing the conditions for regional mobility. This paper explores how policies of infrastructure pricing shape new ways of governing mobility which influences trans-border, regional policy-making. The key findings are that there is a tendency to include...

    Full Text Available Cutaneous melanoma (CM is responsible for 75% of deaths from malignant skin cancer. The incidence of CM in the southern region of Brazil, particularly in the western region of Santa Catarina, is possibly higher than estimated. In this study, the clinical and epidemiological profile of patients with CM treated in the western region of Santa Catarina was examined. A cross-sectional study was performed with patients diagnosed with CM from January 2002 to December 2009, from 78 counties of the western region of the state of Santa Catarina. Data were collected using a protocol adapted from the Brazilian Melanoma Group and 503 patients were evaluated. The incidence and prevalence of CM found in this region are much higher than those found elsewhere in the country. This fact is most likely due to the phenotypic characteristics of the population and the high incidence of UV radiation in this region due to its location in southern Brazil, as is the case in the countries of Oceania.

  12. Transient regional osteoporosis

    Directory of Open Access Journals (Sweden)

    F. Trotta


    Full Text Available Transient osteoporosis of the hip and regional migratory osteoporosis are uncommon and probably underdiagnosed bone diseases characterized by pain and functional limitation mainly affecting weight-bearing joints of the lower limbs. These conditions are usually self-limiting and symptoms tend to abate within a few months without sequelae. Routine laboratory investigations are unremarkable. Middle aged men and women during the last months of pregnancy or in the immediate post-partum period are principally affected. Osteopenia with preservation of articular space and transitory edema of the bone marrow provided by magnetic resonance imaging are common to these two conditions, so they are also known by the term regional transitory osteoporosis. The appearance of bone marrow edema is not specific to regional transitory osteoporosis but can be observed in several diseases, i.e. trauma, reflex sympathetic dystrophy, avascular osteonecrosis, infections, tumors from which it must be differentiated. The etiology of this condition is unknown. Pathogenesis is still debated in particular the relationship with reflex sympathetic dystrophy, with which regional transitory osteoporosis is often identified. The purpose of the present review is to remark on the relationship between transient osteoporosis of the hip and regional migratory osteoporosis with particular attention to the bone marrow edema pattern and relative differential diagnosis.

  13. Ultrasound in regional anaesthesia. (United States)

    Griffin, J; Nicholls, B


    Ultrasound guidance is rapidly becoming the gold standard for regional anaesthesia. There is an ever growing weight of evidence, matched with improving technology, to show that the use of ultrasound has significant benefits over conventional techniques, such as nerve stimulation and loss of resistance. The improved safety and efficacy that ultrasound brings to regional anaesthesia will help promote its use and realise the benefits that regional anaesthesia has over general anaesthesia, such as decreased morbidity and mortality, superior postoperative analgesia, cost-effectiveness, decreased postoperative complications and an improved postoperative course. In this review we consider the evidence behind the improved safety and efficacy of ultrasound-guided regional anaesthesia, before discussing its use in pain medicine, paediatrics and in the facilitation of neuraxial blockade. The Achilles' heel of ultrasound-guided regional anaesthesia is that anaesthetists are far more familiar with providing general anaesthesia, which in most cases requires skills that are achieved faster and more reliably. To this ends we go on to provide practical advice on ultrasound-guided techniques and the introduction of ultrasound into a department.

  14. North American Regional Report

    Energy Technology Data Exchange (ETDEWEB)



    North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

  15. Northeast Regional Biomass Program

    Energy Technology Data Exchange (ETDEWEB)

    Lusk, P.D.


    The Northeast Regional Biomass Program has been in operation for a period of nine years. During this time, state managed programs and technical programs have been conducted covering a wide range of activities primarily aim at the use and applications of wood as a fuel. These activities include: assessments of available biomass resources; surveys to determine what industries, businesses, institutions, and utility companies use wood and wood waste for fuel; and workshops, seminars, and demonstrations to provide technical assistance. In the Northeast, an estimated 6.2 million tons of wood are used in the commercial and industrial sector, where 12.5 million cords are used for residential heating annually. Of this useage, 1504.7 mw of power has been generated from biomass. The use of wood energy products has had substantial employment and income benefits in the region. Although wood and woodwaste have received primary emphasis in the regional program, the use of municipal solid waste has received increased emphasis as an energy source. The energy contribution of biomass will increase as potentia users become more familiar with existing feedstocks, technologies, and applications. The Northeast Regional Biomass Program is designed to support region-specific to overcome near-term barriers to biomass energy use.

    Pacific Northwest Laboratories (PNL) started the Cold Regions Isotope Applications Program in FY-1975 to identify special conditions in the Arctic and similar geographic areas (Cold Regions) where radioisotope power, heater, or sterilization systems would be desirable and economically viable. Significant progress was made in the first year of this program and all objectives for this initial 12-month period were achieved. The major conclusions and recommendations resulting for this effort are described below. The areas of interest covered include: radiosterilization of sewage; heating of septic tanks; and radioisotope thermoelectric generators as power sources for meteorological instruments and navigational aids.

  2. A far-infrared molecular and atomic line survey of the Orion KL region (United States)

    Lerate, M. R.; Barlow, M. J.; Swinyard, B. M.; Goicoechea, J. R.; Cernicharo, J.; Grundy, T. W.; Lim, T. L.; Polehampton, E. T.; Baluteau, J.-P.; Viti, S.; Yates, J.


    We have carried out a high spectral resolution (λ/Δλ ~ 6800-9700) line survey towards the Orion Kleinmann-Low (KL) cluster from 44 to 188 μm. The observations were taken with the Long Wavelength Spectrometer (LWS) in Fabry-Pérot mode, on board the Infrared Space Observatory (ISO). A total of 152 lines are clearly detected and a further 34 features are present as possible detections. The spectrum is dominated by the molecular species H2O, OH and CO, along with [OI] and [CII] lines from photodissociation region (PDR) or shocked gas and [O III] and [NIII] lines from the foreground M42 HII region. Several isotopic species, as well as NH3, are also detected. HDO and H3O+ are tentatively detected for the first time in the far-infrared (FIR) range towards Orion KL. A basic analysis of the line observations is carried out, by comparing with previous measurements and published models and deriving rotational temperatures and column densities in the case of the molecular species. Analysis of the [OI] and [CII] fine structure lines indicates that although a shock model can reproduce the observed [OI] surface brightness levels, it falls short of the observed [CII] level by more than a factor of 30. A PDR model can reproduce the [OI] 63.2 μm and [CII] surface brightness levels within 35 per cent, although overpredicting the LWS [OI] 145.5 μm-emission by a factor of 2.7. The 70 water lines and 22 OH lines detected by the survey appear with mainly P Cygni profiles at the shortest survey wavelengths and with mainly pure emission profiles at the longest survey wavelengths. The emission and absorption velocity peaks of the water and OH lines indicate that they are associated with gas expanding in the outflow from the KL cluster. The estimated column densities are (2-5) × 1014 cm-2 for H2O and (2.5-5.1) × 1016 cm-2 for OH. The 26 detected CO lines confirm the presence of three distinct components, with temperature and column density combinations ranging from 660 K, 6 × 1017

  12. Venus - Phoebe Region (United States)


    This Magellan radar image is of part of the Phoebe region of Venus. It is a mosaic of parts of revolutions 146 and 147 acquired in the first radar test on Aug. 16, 1990. The area in the image is located at 291 degrees east longitude, 19 degrees south latitude. The image shows an area 30 kilometers (19.6 miles) wide and 76 km (47 miles) long. On the basis of Pioneer Venus and Arecibo data, it is known that two major rift zones occur in southern Phoebe Regio and that they terminate at about 20 to 25 degrees south latitude, about 2,000 km (1,240 miles) apart. This image is of an area just north of the southern end of the western rift zone. The region is characterized by a complex geologic history involving both volcanism and faulting. Several of the geologic units show distinctive overlapping or cross cutting relationships that permit identification and separation of geologic events and construction of the geologic history of the region. The oldest rocks in this image form the complexly deformed and faulted, radar bright, hilly terrain in the northern half. Faults of a variety of orientations are observed. A narrow fault trough (about one-half to one km (three tenths to six tenths of a mile) wide is seen crossing the bright hills near the lower part in the middle of the image. This is one of the youngest faults in the faulted, hilly unit as it is seen to cut across many other structures. The fault trough in turn appears to be embayed and flooded by the darker plains that appear in the south half of the image. These plains are interpreted to be of volcanic origin. The dark plains may be formed of a complex of overlapping volcanic flows. For example, the somewhat darker region of plains in the lower left (southwest) corner of the image may be a different age series of plains forming volcanic lava flows. Finally, the narrow bright line crossing the image in its lower part is interpreted to be a fault which cross cuts both plains units and is thus the youngest event in

  13. Active region seismology (United States)

    Bogdan, Tom; Braun, D. C.


    Active region seismology is concerned with the determination and interpretation of the interaction of the solar acoustic oscillations with near-surface target structures, such as magnetic flux concentration, sunspots, and plage. Recent observations made with a high spatial resolution and a long temporal duration enabled measurements of the scattering matrix for sunspots and solar active regions to be carried out as a function of the mode properties. Based on this information, the amount of p-mode absorption, partial-wave phase shift, and mode mixing introduced by the sunspot, could be determined. In addition, the possibility of detecting the presence of completely submerged magnetic fields was raised, and new procedures for performing acoustic holography of the solar interior are being developed. The accumulating evidence points to the mode conversion of p-modes to various magneto-atmospheric waves within the magnetic flux concentration as being the unifying physical mechanism responsible for these diverse phenomena.

  14. Banks, regions and development

    Directory of Open Access Journals (Sweden)

    Pietro Alessandrini


    Full Text Available From the 1980s onwards the banking sectors in all the industrialised countries have been experiencing intense restructuring, aggregation and consolidation, radically changing their ownership structures and geography. Whatever the reasons behind such restructuring processes, the globalisation of the credit markets, the consolidation of banking structures, the removal of barriers to the free location of banks and their penetration of peripheral markets pose two main questions. Will integration of the banking systems lead to a narrowing or a widening of the development gap between regions? What relations will there be between financial centres and the periphery, and how will financial labour be divided between national (international banks and local (regional banks? The aim of this paper is to address such questions in the light of recent developments in the theoretical and empirical literature on financial integration.

    Hazendonk, P.; Brown, M. B.; Byrne, J. M.; Harrison, T.; Mueller, R.; Peacock, K.; Usher, J.; Yalamova, R.; Kroebel, R.; Larsen, J.; McNaughton, R.


    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

  20. Andean region study

    Energy Technology Data Exchange (ETDEWEB)



    New opportunities for climate change mitigation arising from a higher energy integration among Andean Pact nations were analysed within the framework of the UNEP/GEF Project. Apart from the search for regional mitigation actions, the study was mainly aimed at detecting methodological problems which arise when passing from a strictly national view to the co-ordination of regional actions to deal with climate change. In accordance with the available resources and data, and in view of the mainly methodological nature of the project, it was decided to analyse the opportunities to delve into the energy integration of the Region as regards electricity and natural gas industries and their eventual impact on the emission of greenhouse gases. Although possibilities of setting up electricity and natural gas markets are real, their impacts on GHG emission from the energy system would not prove substantially higher than those which the nations could achieve through the use of their own energy resources, in view that the Andean systems are competitive rather than complementary. More in-depth studies and detail information will be required - unavailable for the present study - to be able to properly evaluate all benefits associated with higher energy integration. Nevertheless, the supply of natural gas to Ecuador seems to be the alternative with the highest impact on GHG emission. If we were to analyse the supply and final consumption of energy jointly, we would most certainly detect additional mitigation options resulting from higher co-operation and co-ordination in the energy field.

    Full Text Available The purpose of this contribution is to discuss what roles the different economic sectors, and in particular services activities (the tertiary sector play in regional development, understood as growth in production, incomes and employment in weakly developedregions. This question is approached in two ways. The contribution first contains a – primarily theoretical – re-examination of the so-called economic base model, which states that services play a passive role in regional development. The discussion leads to substantial modifications of the model. The second approach is more empirical. It will take as its point of departure the proposition – often heard, but rarely examined – that since service activities are more concentrated in big cities than other activities and in recent decades have shown higher growth rates than other economic activities, it follows that the economic development is now pulled towards big city regions. Examined by way of a statistical analysisin Denmark and France, this proposition could not be verified.

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

The NGC 3603 region The new VLT observations are the key part of a larger research programme that also includes observations of the stellar cluster in the famous Tarantula Nebula in the Large Magellanic Cloud (LMC) with the NICMOS instrument on the Hubble Space Telescope (HST), as well as adaptive optics observations with ground-based telescopes of more quiescent, star-forming regions in the Galaxy. However, the team considered the starburst region NGC 3603 as the best target for this kind of investigation. It is situated in the far southern constellation Carina (The Keel) and can only be observed from the South. Moreover, such a study has to focus on the densest part of the cluster that can only be resolved with a very sensitive infrared (IR) instrument under the best seeing conditions. The VLT ANTU telescope and the multi-mode ISAAC facility are ideally suited for this purpose. NGC 3603 is located in the Carina spiral arm in the Milky Way galaxy at a distance of about 20,000 light-years (6 - 7 kpc). It is the only massive, galactic "HII-region" (so denoted by astronomers because part of its hydrogen is ionized) in which a central cluster of strongly UV-radiating stars of types "O" and "B" that ionize the nebula can be studied at visual and near-infrared wavelengths. This is because the line-of-sight is reasonably free of dust in this direction; the dimming in near-infrared radiation due to intervening matter between the nebula and us is only about a factor of 2 (contrary to 80 in visible light). The total mass of the hot O- and B-stars in NGC 3603 is over 2000 solar masses. Together, the more than fifty heavy and bright O-stars in NGC 3603 have about 100 times the ionizing power of the well

  6. Filamentary structure and Keplerian rotation in the high-mass star-forming region G35.03+0.35 imaged with ALMA (United States)

    Beltrán, M. T.; Sánchez-Monge, Á.; Cesaroni, R.; Kumar, M. S. N.; Galli, D.; Walmsley, C. M.; Etoka, S.; Furuya, R. S.; Moscadelli, L.; Stanke, T.; van der Tak, F. F. S.; Vig, S.; Wang, K.-S.; Zinnecker, H.; Elia, D.; Schisano, E.


    Context. Theoretical scenarios propose that high-mass stars are formed by disk-mediated accretion. Aims: To test the theoretical predictions on the formation of massive stars, we wish to make a thorough study at high-angular resolution of the structure and kinematics of the dust and gas emission toward the high-mass star-forming region G35.03+0.35, which harbors a disk candidate around a B-type (proto)star. Methods: We carried out ALMA Cycle 0 observations at 870 μm of dust of typical high-density, molecular outflow, and cloud tracers with resolutions of 107 cm -3, and masses in the range 1-5 M⊙, and they are subcritical. Core A, which is associated with a hypercompact Hii region and could be the driving source of the molecular outflow observed in the region, is the most chemically rich source in G35.03+0.35 with strong emission of typical hot core tracers such as CH3CN. Tracers of high density and excitation show a clear velocity gradient along the major axis of the core, which is consistent with a disk rotating about the axis of the associated outflow. The PV plots along the SE-NW direction of the velocity gradient show clear signatures of Keplerian rotation, although infall could also be present, and they are consistent with the pattern of an edge-on Keplerian disk rotating about a star with a mass in the range 5-13 M⊙. The high tff/trot ratio for core A suggests that the structure rotates fast and that the accreting material has time to settle into a centrifugally supported disk. Conclusions: G35.03+0.35 is one of the most convincing examples of Keplerian disks rotating about high-mass (proto)stars. This supports theoretical scenarios according to which high-mass stars, at least B-type stars, would form through disk-mediated accretion. Appendices are available in electronic form at

  7. Southeast Regional Experiment Station (United States)


    This is the final report of the Southeast Regional Experiment Station project. The Florida Solar Energy Center (FSEC), a research institute of the University of Central Florida (UCF), has operated the Southeast Regional Experiment Station (SE RES) for the US Department of Energy (DOE) since September 1982. Sandia National Laboratories, Albuquerque (SNLA) provides technical program direction for both the SE RES and the Southwest Regional Experiment Station (SW RES) located at the Southwest Technology Development Institute at Las Cruces, New Mexico. This cooperative effort serves a critical role in the national photovoltaic program by conducting system evaluations, design assistance and technology transfer to enhance the cost-effective utilization and development of photovoltaic technology. Initially, the research focus of the SE RES program centered on utility-connected PV systems and associated issues. In 1987, the SE RES began evaluating amorphous silicon (a-Si) thin-film PV modules for application in utility-interactive systems. Stand-alone PV systems began receiving increased emphasis at the SE RES in 1986. Research projects were initiated that involved evaluation of vaccine refrigeration, water pumping and other stand-alone power systems. The results of this work have led to design optimization techniques and procedures for the sizing and modeling of PV water pumping systems. Later recent research at the SE RES included test and evaluation of batteries and charge controllers for stand-alone PV system applications. The SE RES project provided the foundation on which FSEC achieved national recognition for its expertise in PV systems research and related technology transfer programs. These synergistic products of the SE RES illustrate the high visibility and contributions the FSEC PV program offers to the DOE.

  11. Complex regional pain syndrome

    Directory of Open Access Journals (Sweden)

    Sandeep J Sebastin


    Full Text Available Complex regional pain syndrome (CRPS previously known as reflex sympathetic dystrophy is a chronic neurological disorder involving the limbs characterized by disabling pain, swelling, vasomotor instability, sudomotor abnormality, and impairment of motor function. CRPS is not uncommon after hand surgery and may complicate post-operative care. There is no specific diagnostic test for CRPS and the diagnosis is based on history, clinical examination, and supportive laboratory findings. Recent modifications to diagnostic criteria have enabled clinicians to diagnose this disease more consistently. This review gives a synopsis of CRPS and discusses the diagnosis, pathophysiology, and treatment options based on the limited evidence in the literature.

    Drug information centers (DICs) were established in Europe more than two decades ago. The majority of German DICs were created in the 90s. The regional University hospital-based DIC, which offers services to physicans, is now in operation for three and a half years . To evaluate the types of enquiries received and the profile of the users of a drug information service. The working procedure at a regional center in Dresden, Germany, is described. The topics for consultation (adverse reactions, pharmacokinetics, etc.) are presented, and the types of drugs involved are classified according to the Anatomical Therapeutic Chemical (ATC) classification. Users are grouped by medical specialty. Future plans for the DIC are discussed. A total of 516 enquiries were received. Questions concerning therapeutic use (34%), adverse drug reactions (28%), pregnancy/lactation (16%), and pharmacokinetics/dosage (15%) were asked most frequently. Cardiovascular drugs (20%), systemic antiinfectives (19%) as well as drugs targeting the central nervous system (15%) and alimentation/metabolism (9%) were the predominant foci of enquiries. The major users of the DIC were internists (19%), general practitioners (19%), pediatricians (18%), and gynecologists (11%). The types of questions and users of this service were generally similar to those recorded at many other European DICs. The service has begun producing educational bulletins on drug-related topics of clinical relevance.

    Complex regional pain syndrome (CRPS) represents a state of constant and often disabling pain, affecting one region (usually hand) and often occurs after a trauma whose severity does not correlate with the level of pain. The older term for this condition of chronic pain associated with motor and autonomic symptoms is reflex sympathetic dystrophy or causalgia. The aim of this review, based on contemporary literature, is to show the epidemiology and etiology, proposed pathophysiological mechanisms, method of diagnosis and treatment options, prevention and mitigation of this under-recognized disease. CRPS I occurs without known neurological damage, unlike CRPS II, where the history of trauma is present and in some cases damage to the peripheral nervous system can be objectively assessed using electromyoneurography. New diagnostic methods, such as quantitative sensory testing (CST), challenge this division because the CST findings in patients with CRPS I can suggest damage to Adelta peripheral nerve fibers. Except for distinguishing type I and type II disease, it is important to bear in mind the diversity of clinical presentation of CRPS in acute and chronic phase of the disease. This regional pain syndrome typically includes the autonomic and motor signs and thus differs from other peripheral neuropathic pain syndromes. The complexity of the clinical presentation indicates the likely presence of different pathophysiological mechanisms underlying this disease. Previous studies have demonstrated the autonomic dysfunction, neurogenic inflammation and neuroplastic changes. The diagnosis of CRPS is based on anamnesis and clinical examination on the basis of which the disease can be graded according to the Budapest Criteria. A valuable aid in differentiating subtypes of the disease is electromyoneurography. The treatment of CRPS is as complex as the clinical picture and the pathophysiology of the disease and requires interdisciplinary cooperation and individual approach

    Olga Vladimirovna Kudelina


    Full Text Available An evaluation of healthcare systems effectiveness of the regions of the Russian Federation (federal districts was conducted using the Minmax method based on the data available at the United Interdepartmental Statistical Information System. Four groups of components (i.e. availability of resources; use of resources; access to resources and medical effectiveness decomposed into 17 items were analyzed. The resource availability was measured by four indicators, including the provision of doctors, nurses, hospital beds; agencies providing health care to the population. Use of resources was measured by seven indicators: the average hospital stay, days; the average bed occupancy, days; the number of operations per 1 physician surgical; the cost per unit volume of medical care: in outpatient clinics, day hospitals, inpatient and emergency care. Access to the resources was measured by three indicators: the satisfaction of the population by medical care; the capacity of outpatient clinics; the average number of visits to health facility. The medical effectiveness was also measured by three indicators: incidence with the "first-ever diagnosis of malignancy"; life expectancy at birth, years; the number of days of temporary disability. The study of the dynamics of the components and indexes for 2008–2012 allows to indicate a multidirectional influence on the regional healthcare system. In some federal districts (e.g. North Caucasian, the effectiveness decreases due to resource availability, in others (South, North Caucasian — due to the use of resources, in others (Far Eastern, Ural — due to access to resources. It is found that the effectiveness of the healthcare systems of the federal districts differs significantly. In addition, the built matrix proves the variability the of effectiveness (comparison of expenditures and results of healthcare systems of the federal districts of the Russian Federation: the high results can be obtained at high costs

    This work presents an approach for the planning of transmission systems by employing mixed--integer linear programming to obtain a cost and operating characteristics optimized system. The voltage loop equations are written in a modified form, so that, at the end of the analysis, the model behaves as a DC power flow, with the help of the two Kirchhoff`s laws, exempting the need of interaction with an external power flow program for analysis of the line loading. The model considers the occurrence of contingencies, so that the final result is a network robust to the most severe contingencies. This whole technique is adapted to the regional electric power transmission subsystems. (author) 9 refs., 4 figs.

  7. Regional brain hypometabolism is unrelated to regional amyloid plaque burden. (United States)

    Altmann, Andre; Ng, Bernard; Landau, Susan M; Jagust, William J; Greicius, Michael D


    In its original form, the amyloid cascade hypothesis of Alzheimer's disease holds that fibrillar deposits of amyloid are an early, driving force in pathological events leading ultimately to neuronal death. Early clinicopathological investigations highlighted a number of inconsistencies leading to an updated hypothesis in which amyloid plaques give way to amyloid oligomers as the driving force in pathogenesis. Rather than focusing on the inconsistencies, amyloid imaging studies have tended to highlight the overlap between regions that show early amyloid plaque signal on positron emission tomography and that also happen to be affected early in Alzheimer's disease. Recent imaging studies investigating the regional dependency between metabolism and amyloid plaque deposition have arrived at conflicting results, with some showing regional associations and other not. We extracted multimodal neuroimaging data from the Alzheimer's disease neuroimaging database for 227 healthy controls and 434 subjects with mild cognitive impairment. We analysed regional patterns of amyloid deposition, regional glucose metabolism and regional atrophy using florbetapir ((18)F) positron emission tomography, (18)F-fluordeoxyglucose positron emission tomography and T1-weighted magnetic resonance imaging, respectively. Specifically, we derived grey matter density and standardized uptake value ratios for both positron emission tomography tracers in 404 functionally defined regions of interest. We examined the relation between regional glucose metabolism and amyloid plaques using linear models. For each region of interest, correcting for regional grey matter density, age, education and disease status, we tested the association of regional glucose metabolism with (i) cortex-wide florbetapir uptake; (ii) regional (i.e. in the same region of interest) florbetapir uptake; and (iii) regional florbetapir uptake while correcting in addition for cortex-wide florbetapir uptake.

  9. Regional Sociological Research Experience

    Directory of Open Access Journals (Sweden)

    Mikhail Vladimirovich Morev


    Full Text Available The article presents the experience of the Institute of Socio-Economic Development of Territories of RAS in conducting sociological research on the territory of the Vologda Oblast and the Northwestern Federal District. It describes the historical aspects of formation of the system for public opinion monitoring and examines its theoretical and methodological foundations. The author of the article analyzes the structure of monitoring indicators and provides a brief interpretation of research findings that reflect social wellbeing and social perception trends. In addition, the paper analyzes people’s attitude toward the activities of federal and regional authorities, trends in social well-being, consumer sentiment and also the complex indicator – the index of public sentiment in the region – developed by ISEDT RAS researchers. The results of sociological studies carried out at ISEDT RAS correlate with the dynamics of the all-Russian public opinion polls conducted by the Institute of Sociology of the Russian Academy of Sciences, the Russian Public Opinion Research Center (VCIOM, Levada-Center, etc. They indicate that Russian society gradually adapts to new conditions of life after the collapse of the USSR. Besides, opinion polls show the most important features of the post-Soviet Russian history at its present stage; they are associated with the intensification of international political relations, the consequences of the “Crimean spring” and the new challenges Russia’s economy is facing now. The article concludes that as global community, of which Russian society is part, is evolving, sociological knowledge begins to play an increasingly important role in administration and national security; this is associated with the greater importance attached to intangible development factors. Therefore, a necessary prerequisite for administration effectiveness in all its stages is to implement the results of sociological research on social

  10. Landslides of Palestinian Region (United States)

    Alwahsh, H.


    Natural disasters are extreme sudden events caused by environmental and natural actors that take away the lives of many thousands of people each year and damage large amount of properties. They strike anywhere on earth, often without any warning. A risk maps of natural disaster are very useful to identify the places that might be adversely affected in the event of natural disaster. The earthquakes are one of natural disaster that have the greatest hazards and will cause loss of life and properties due to damaging the structures of building, dams, bridges. In addition, it will affect local geology and soil conditions. The site effects play an important role in earthquake risk because of its amplification or damping simulation. Another parameter in developing risk map is landslide, which is also one of the most important topics in site effect hazards. Palestine region has been suffering landslide hazards because of the topographical and geological conditions of this region. Most Palestine consists of mountainous area, which has great steep slopes and the type of soil is mainly grayish to yellowish silty clay (Marl Soil). Due to the above mentioned factors many landslides have been occurred from Negev south to the northern borders of Palestine. An example of huge and destruction landslide in a Palestine authority is the landslide in the White Mountain area in the city of Nablus, which occurred in 1997. The geotechnical and geophysical investigation as well as slope stability analysis should be considered in making landslide maps that are necessary to develop risk levels of the natural disaster. Landslides occurred in slopes that are created naturally or by human beings. Failure of soil mass occurs, and hence landslide of soil mass happen due to sliding of soil mass along a plane or curved surface. In general, the slopes become unstable when the shear stresses (driving force) generated in the soil mass exceed the available shearing resistance on the rupture surface

  16. Evolution of Active Regions

    Directory of Open Access Journals (Sweden)

    Lidia van Driel-Gesztelyi


    Full Text Available The evolution of active regions (AR from their emergence through their long decay process is of fundamental importance in solar physics. Since large-scale flux is generated by the deep-seated dynamo, the observed characteristics of flux emergence and that of the subsequent decay provide vital clues as well as boundary conditions for dynamo models. Throughout their evolution, ARs are centres of magnetic activity, with the level and type of activity phenomena being dependent on the evolutionary stage of the AR. As new flux emerges into a pre-existing magnetic environment, its evolution leads to re-configuration of small-and large-scale magnetic connectivities. The decay process of ARs spreads the once-concentrated magnetic flux over an ever-increasing area. Though most of the flux disappears through small-scale cancellation processes, it is the remnant of large-scale AR fields that is able to reverse the polarity of the poles and build up new polar fields. In this Living Review the emphasis is put on what we have learned from observations, which is put in the context of modelling and simulation efforts when interpreting them. For another, modelling-focused Living Review on the sub-surface evolution and emergence of magnetic flux see Fan (2009. In this first version we focus on the evolution of dominantly bipolar ARs.

    Energy Technology Data Exchange (ETDEWEB)

    Lienau, P.J. [ed.


    The Svartsengi geothermal area is close to the town of Grindavik on the Rekjanes peninsula and is part of an active fissure swarm, lined with crater-rows and open fissures and faults. The high-temperature area has an area of 2 sq. km and shows only limited signs of geothermal activity at the surface. The reservoir, however, contains lots of energy and at least 8 wells supply the Svartsengi Power Plant with steam. The steam is not useable for domestic heating purposes so that heat exchangers are used to heat cold groundwater with the steam. Some steam is also used for producing 16.4 MW{sub e} of electrical power. The article shows the distribution system piping hot water to nine towns and the Keflavik International Airport. The effluent brine from the Svartsengi Plant is disposed of into a surface pond, called the Blue Lagoon, popular to tourists and people suffering from psoriasis and other forms of eczema seeking therapeutic effects from the silica rich brine. This combined power plant and regional district heating system (cogeneration) is an interesting and unique design for the application of geothermal energy.

  18. Regional odontodysplasia: case report

    Directory of Open Access Journals (Sweden)

    Ana Carolina Magalhães


    Full Text Available Regional odontodysplasia (RO is a rare developmental anomaly involving both mesodermal and ectodermal dental components in a group of contiguous teeth. It affects the primary and permanent dentitions in the maxilla and mandible or both jaws. Generally it is localized in only one arch. The etiology of this dental anomaly is uncertain. Clinically, affected teeth have an abnormal morphology, are soft on probing and typically discolored, yellow or yellowish-brown. Radiographically, the affected teeth show a "ghostlike" appearance. This paper reports the case of a 5-year-old girl presenting this rare anomaly on the left side of the maxillary arch, which crossed the midline. The primary maxillary left teeth (except for the canine and the primary maxillary right central incisor were missing due to previous extractions. The permanent teeth had a "ghostlike" appearance radiographically. The treatment performed was rehabilitation with temporary partial acrylic denture and periodic controls. In the future, the extraction of affected permanent teeth and rehabilitation with dental implants will be evaluated. The presentation of this case adds valuable information to pediatric dentists to review special clinical and radiographic features of RO, which will facilitate the diagnosis and treatment of patients with this condition.

    Tripković Gordana D.


    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

  2. Thinking regionally: narrative, the medical humanities and region. (United States)

    Waddington, Keir


    Drawing on multiple literatures from history, geography, anthropology, sociology and literature, this essay asks questions about what we mean by region and why narratives of region should matter to the medical humanities. The essay surveys how region can be used as a lens of analysis, exploring the various academic approaches to region and their limitations. It argues that regions are dynamic but also unstable as a category of analysis and are often used uncritically by scholars. In encouraging scholars working in the medical humanities to be aware that regions are not simple objective or analytical boxes, the essay shows how an awareness of region helps challenge metropolitan whiggism and ideas of core and periphery to give a more prominent place to hinterlands, market towns and rural environments. Furthermore, the essay considers how incorporating region into our understanding of illness can offer new insights. It demonstrates the need for scholars to be attuned to the narratives constructed around regions, suggesting that regions can be viewed as discursive formations that provide a frame for understanding both collective and personal ideas of, and responses to, health and illness, disease and healing, to create what Megan Davies calls a more nuanced 'intellectual cartography'.

  3. Caspian Region in the System of International Regions

    Directory of Open Access Journals (Sweden)

    Kosov Gennadiy Vladimirovich


    Full Text Available The given research paper presents an attempt to analyze the Caspian region from the point of view of its cross-border specifics. In contrast to the traditional understanding of the Caspian region as the region of heightened geopolitical significance the authors analyze its peculiarities and potential in the context of the cross-border cooperation dynamics. It is especially emphasized that the Caspian region may be considered as a cross-border region which, despite the substantial similarities is different from international transnational regions. The authors focus attention on a key contradiction of the Caspian region. On the one hand, national interests and foreign policy of the states-members of the Caspian region (Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan have a national country and regional importance, since their implementation will form an effective regional security system. On the other hand, the Caspian region attracts the attention of the world powers, becoming a subject of their interest, as it is of great importance for world energy markets and has status of a transit zone between Europe and Asia. For Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan the Caspian status is combined with their most important characteristic of post-Soviet states - shared long historical stage of development within the Soviet Union. The article distinguished and analyzed four main periods of establishment of cross-border cooperation in the Caspian region. The national specificity of modernization reforms in all the countries of the Caspian region have interrelations with further development of cross-border cooperation, the priority of that performs convergence of Caspian states on a number of strategic issues, including economic cooperation and security.

  4. Regional reserves of energy efficiency

    Directory of Open Access Journals (Sweden)

    Igor Aleksandrovich Bayev


    Full Text Available The article is devoted to the study of peculiarities of power consumption and energy efficiency of the Russian regions. The level of energy efficiency in Russia compared with other countries of the world is analyzed. The indicators of energy consumption and industrial structure of the regions are compared. The dependence of the electricity consumption in the regions and the gross regional product per capita is studied. Based on the made analysis, the map of electricity consumption in the regions demonstrating the high level of differentiation of Russian regions on a level of energy efficiency is formulated. The authors have suggested the recommendations on the selection of priority directions of implementation of energy conservation policy for the subjects of the Russian Federation. On the example of the Chelyabinsk region, the features of realization of the regional program on energy efficiency are considered. The ways of its improvement on the basis of developed are offered by the authors of the matrix electricity consumption. Research results have practical significance and can be used to improve existing regional energy saving programs for individual sectors of the regional economy, and for the regions in general

  5. Food Independence of the Region

    Directory of Open Access Journals (Sweden)

    Vasiliy Vladimirovich Tyutyunik


    Full Text Available The article deals with such basic definitions as food security, food independence and food self- sufficiency of the region. The author shows the ambiguity problem of interpretations of these terms in the Russian legislation, which is especially evident in the transition from the national to the regional level. Using the example of legislative acts of some of the Russian Federation’s subjects the study demonstrates the incorrect use of mentioned terms. In author’s opinion, regional authorities in the Russian Federation must introduce amendments to the legislative documents concerning food security. To be more concrete, the regional authorities should either deny the goal of food independence for a particular region, or specify that the goal of reaching food independence for the region does not mean food self-sufficiency, but just import substitution on the regional level

  7. The creation of regional partnerships for regional emergency planning. (United States)

    Myers, Laura; Myers, Larry; Grant, Lorna


    Regional partnerships for regional emergency planning are relationships developed between disparate emergency planning stakeholders from multiple jurisdictions and with different missions. Regional partnerships are essential for the management of limited resources and for responding to large-scale disasters that can overwhelm local resources. Emergency response planners develop these partnerships as needs develop within their own jurisdictions or in response to lessons learned from previous disaster responses. This paper discusses a model process for developing or enhancing an all-hazards regional emergency planning network to create regional collaboration and resource allocation. This model process can be adapted and customised in any community to develop partnerships between communities, public agencies, non-governmental organisations, faith-based organisations and the private sector within a region. The model process and how to use it in communities will be discussed, including a qualitative analysis of its application.

    Directory of Open Access Journals (Sweden)

    Drozdova Yuliya


    Full Text Available The paper analyzes findings yielded by the empirical study performed in the framework of an RGNF grant entitled “Image of a region as a communicative strategy for the authorities and mass media”. The methods of study included expert survey and formal survey (N=1000, July-September 2013, studying the opinion of respondents who were either internal experts residing in the Volgograd region (N=20; May-September 2013 or external experts who reside outside the region but maintain stable ties with the representatives of state and municipal authorities, regional mass media and business. The findings indicate that the Volgograd region has fallen behind other modernized Russian regions, that young people tend to leave it, that a negative image of the region as a declining territory persists. Answers to the open question “What is unacceptable for you in the existing image of the Volgograd region?” revealed major problems determining the local context of a declining region, and those were issues associated with inefficient regional/municipal administration: “the condition of the roads”, “constant replacement of people in the administration”, “politics as a whole”, “a destitute region without a good manager”, “unemployment”, “countryside is dying off”, “indifference of the authorities”, “roads, housing and public utilities and the administration”, “the authorities are not responsible for the people”, “the authorities do not solve the problems of the city or its people”, “thieving”, “dishonest authorities”, “the region goes to rack and ruin, no kindergartens or jobs”, “one cannot even walk in the streets”, “corruption”, “a stagnant region with low pay”, “no perspectives in the future”, “the region is stagnating due to corruption among officials”. According to the local Census Bureau, the Volgograd region can be classified as a declining territory where the population decline

  10. Regional governance: strategies and disputes in health region management (United States)

    dos Santos, Adriano Maia; Giovanella, Ligia


    OBJECTIVE To analyze the regional governance of the health systemin relation to management strategies and disputes. METHODOLOGICAL PROCEDURES A qualitative study with health managers from 19 municipalities in the health region of Bahia, Northeastern Brazil. Data were drawn from 17 semi-structured interviews of state, regional, and municipal health policymakers and managers; a focus group; observations of the regional interagency committee; and documents in 2012. The political-institutional and the organizational components were analyzed in the light of dialectical hermeneutics. RESULTS The regional interagency committee is the chief regional governance strategy/component and functions as a strategic tool for strengthening governance. It brings together a diversity of members responsible for decision making in the healthcare territories, who need to negotiate the allocation of funding and the distribution of facilities for common use in the region. The high turnover of health secretaries, their lack of autonomy from the local executive decisions, inadequate technical training to exercise their function, and the influence of party politics on decision making stand as obstacles to the regional interagency committee’s permeability to social demands. Funding is insufficient to enable the fulfillment of the officially integrated agreed-upon program or to boost public supply by the system, requiring that public managers procure services from the private market at values higher than the national health service price schedule (Brazilian Unified Health System Table). The study determined that “facilitators” under contract to health departments accelerated access to specialized (diagnostic, therapeutic and/or surgical) services in other municipalities by direct payment to physicians for procedure costs already covered by the Brazilian Unified Health System. CONCLUSIONS The characteristics identified a regionalized system with a conflictive pattern of governance and

    Khadiagala, Gilbert M.


    Since the 1960s, African states have embraced regional integration as a vital mechanism for political cooperation and for pooling resources to overcome problems of small and fragmented economies. In building meaningful institutions for regionalism, however, Africans have faced the challenges of reconciling the diversities of culture, geography, and politics. As a result, African regional institutions are characterized by multiple and competing mandates and weak institutionalization. This stud...

The imbalances in the levels of development of various territorial units of Serbia (regional disproportions are the consequence of many structural disharmonies, material limitations, and problems with populationstructure, during many years, all worsened by political and economic events at the end of the twentieth century. Also, in this paper we point out the main characteristics of undeveloped regions, the criteria with which we can define them, and a typology of the municipalities inside each such region.

  18. Regions and the Territorial Cohesion

    Directory of Open Access Journals (Sweden)

    Ioan Ianos


    Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

Hence, regional strategies can, we argue, be useful. Yet, these strategies must be tailored to meet a variety of contextual conditions. Within this study, we identified natural and socio-economic conditions that need to be considered when developing regional strategies for Energiewende. Focusing on these conditions, we conducted a multivariate statistical analysis of all 412 German districts (Landkreise. We identified nine energy context types characterized by different renewable energy potentials and socio-economic conditions. We propose to develop one generic regional energy transition strategy for each of the energy context types. These can serve as a governance tool that operationalizes and allocates national Energiewende goals according to regional contextual conditions. Moreover, the energy context types may support regional decision makers by allowing them to prioritize steps in the transition process, to establish networks with, and to learn from, similar regions.

  2. Analysis of regional climate strategies in the Barents region

    Energy Technology Data Exchange (ETDEWEB)

    Himanen, S.; Inkeroeinen, J.; Latola, K.; Vaisanen, T.; Alasaarela, E.


    Climate change is a global phenomenon with especially harsh effects on the Arctic and northern regions. The Arctic's average temperature has risen at almost twice the rate as elsewhere in the past few decades. Since 1966, the Arctic land area covered by snow in early summer has shrunk by almost a fifth. The Barents Region consists of the northern parts of Norway, Sweden, Finland and Russia (i.e. the European part of Russia). Climate change will cause serious impacts in the Barents Region because of its higher density of population living under harsh climatic conditions, thus setting it apart from other Arctic areas. In many cases, economic activities, like tourism, rely on certain weather conditions. For this reason, climate change and adaptation to it is of special urgency for the region. Regional climate change strategies are important tools for addressing mitigation and adaptation to climate change as they can be used to consolidate the efforts of different stakeholders of the public and private sectors. Regional strategies can be important factors in achieving the national and international goals. The study evaluated how the national climate change goals were implemented in the regional and local strategies and programmes in northern Finland. The specific goal was to describe the processes by which the regional strategies were prepared and implemented, and how the work was expanded to include the whole of northern Finland. Finally, the Finnish preparatory processes were compared to case examples of processes for preparing climate change strategies elsewhere in the Barents Region. This analysis provides examples of good practices in preparing a climate change strategy and implementing it. (orig.)

    Klára Margarisová


    Full Text Available Regional branding is one of several ways to promote rural regions and support development of socially, culturally and environmentally oriented economies in areas that are interesting due to their natural and cultural heritage. The article attempts to review the conceptual and theoretical underpinnings of branding as conveyed by leading authors in the marketing field. The aim of this paper is to define brand as a broad complex of variables, which are used in building of its identity as a basis for creating value proposition and the position of a brand. Article briefly describes the most comprehensive labeling system for regional products at the micro-regional level is the one guaranteed by Association of Regional Brands (ARB. The main contribution of this article is a theoretical model of strategic management of a regional brand, which captures the interdependence of the individual steps of brand building as well as stakeholders. The starting point for building of brand value is a strategic analysis of the brand, including analysis of customer and competitors. The analysis of external factors is followed by analysis of the brand itself. The resulting relationship between the brand and the customer is based on value proposition representing benefits (functional, emotional, self‑expression. The concept of total product is connected with the concept of total brand and it is offered to the customer as a regional product. Finally it suggests possibilities for further research.

  8. From Concept of the Region to Regional Image of Montenegro

    Goran Rajović


    Full Text Available The focus of work is the understanding of the problems of regional development in recent times is becoming increasingly important socio - economic issue. The paper seeks to argue that the context and Regional Development provides an opportunity to resolve the paradox of development interpreted by many researchers. Issues of Regional Development of Montenegro for more than half a century did not have adequate theoretical or practical foundation. New current models of economic growth and development were based on sector priorities and policies, the short and medium term objectives. In order to slow down the aging process of the population of Montenegro and mitigate its effects, it is necessary to increase the birth rate, which would encourage the gradual rejuvenation of the population. The second group of measures relates to immigration, and the third to increase youth employment in order to prevent any more numerous emigrations. The problem employment/unemployment is one of the most socio - economic problems in Montenegro. Therefore, in the management regional development policy at EU level, special importance is given to finding adequate mechanisms and instruments that will contribute to the better functioning of labor markets, and thus to a more balanced regional development. In Montenegro, it is necessary to elaborate a new concept, a comprehensive regional development, which will be based on demographic, natural, economic and socio-cultural resources.

  9. Regional strategies for global leadership. (United States)

    Ghemawat, Pankaj


    The leaders of such global powerhouses as GE, Wal-Mart, and Toyota seem to have grasped two crucial truths: First, far from becoming submerged by the rising tide of globalization, geographic and other regional distinctions may in fact be increasing in importance. Second, regionally focused strategies, used in conjunction with local and global initiatives, can significantly boost a company's performance. The business and economic data reveal a highly regionalized world. For example, trade within regions, rather than across them, drove the surge of international commerce in the second half of the twentieth century. Regionalization is also apparent in foreign direct investment, companies' international sales, and competition among the world's largest multinationals. Harvard Business School Professor Pankaj Ghemawat says that the most successful companies employ five types of regional strategies in addition to--or even instead of--global ones: home base, portfolio, hub, platform, and mandate. Some companies adopt the strategies in sequence, but the most nimble switch from one to another and combine approaches as their markets and businesses evolve. At Toyota, for example, exports from the home base continue to be substantial even as the company builds up an international manufacturing presence. And as Toyota achieves economies of scale and scope with a strong network of hubs, the company also pursues economies of specialization through interregional mandates. Embracing regional strategies requires flexibility and creativity. A company must decide what constitutes a region, choose the most appropriate strategies, and mesh those strategies with the organization's existing structures. In a world that is neither truly global nor truly local, finding ways of coordinating within and across regions can deliver a powerful competitive advantage.

    The purpose of this paper is to explore some of the key methodological issues that arise from an analysis of regional climate change mitigation options. The rationale for any analysis of regional mitigation activities, emphasising both the theoretical attractiveness and the existing political encouragement and the methodology that has been developed are reviewed. The differences arising from the fact that mitigation analyses have been taken from the level of the national - where the majority of the work has been completed to date - to the level of the international - that is, the `regional` - will be especially highlighted.

    The rationale for conducting climate change mitigation studies in the transport sector is on the premise that: The transport sector is the second largest consumer of fossil fuels in the region; The regional transport sector is an area with high opportunity for infrastructural development under UNFCCC financial mechanism; The regional transport sector is crucial in the SADC region for trade and coupled with the Trade Protocol will play a major role in development hence the need to make it efficient in terms of energy demand and provision of services; The sector offers many mitigation options but with a challenge to evaluate their energy saving and GHG saving potential and yet there is need to quantify possible emission reduction for possible future emission trading. This is also a sector with potential to qualify for financing through Clean Development Mechanism (CDM) recently stipulated in the Kyoto Protocol. (au)

    Jitka Kalábová


    Full Text Available This paper presents partial results of a research on consumer preferences when shopping for groceries. It is focused on regional products and consumer preferences in relation to the country of origin of food products. The main objective of this paper is to find the existence of spatial relationships between spatial deployment of regional products and consumer preferences for regional products. It will be necessary to create a data model for monitoring the deployment of regional products and also a data model for tracking important indicators of consumer behavior in all regions of the Czech Republic. The results are based on questionnaire survey that was conducted within the period from October 2010 to January 2011 on a sample of 3767 respondents from the Czech Republic, via both online questionnaires and their printed version. For the data collection the questionnaire system ReLa, developed by the Department of Marketing and Trade at Faculty of Business and Economics at Mendel University in Brno, was used. Data was processed with statistical software STATISTICA (ver. 10. Spatial visualisation was processed with GIS software ArcGIS (ver. 10.1. Preferences for food of Czech origin were analysed in relation to identification criteria. The research results show that the origin of food has an important role in consumer purchase decision-making. There is no significant difference in importance of this factor based on gender of consumers, however, we could prove moderate dependence on respondent’s occupation, education and age. We could also experience regional differences in levels of preferences of local products or products of Czech origin in regard of 14 regions of the Czech Republic. χ2 (N = 3767 = 245.25; p < 0.001. Value of Pearson’s coefficient of contingency is 0.334.

  17. New Geographical Regionalization of Russia

    Directory of Open Access Journals (Sweden)

    Vladimir A. Gorbanyov


    Full Text Available After the October Revolution there was an urgent need for a new economic zoning of Russia. Under the leadership of the greatest scientists the Soviet Union was divided in to economic regions. After the collapse of the USSR and the emergence of a market economy, these regions have lost their meaning, and the new were not created. Therefore there was a need of a new zoning Russia, and not by economic regions, but by the complex geographical regions. This is a difficult task, but because of the author's opinion that geography should be a single, new geographical areas should reflect their historical, natural, economic, social, cultural view specifics. This approach will promote rational geographical division of labor in the country in a market economy. An attempt to new geographical zoning, with 10 allocated geographic regions: Capital, Central, European North, European South, North Caucasus, Volga-Urals, Western Siberia, Southern Siberia, Northern Siberia and the Far East. For each region area, population size and density, level of urbanization, natural, mechanical and overall population growth, GDP per capita, the structure of employment, Human Development Index were counted, and the appropriate analysis were made.

  18. Social attitudes and regional inequalities

    Directory of Open Access Journals (Sweden)

    Vinko Muštra


    Full Text Available As the budgets of the European Union (EU become tighter, the questions about the effectiveness of EU’s expenditure, especially the most important parts such as Cohesion policy, are hotly debated. The aim of this paper is to examine whether the presence of social attitudes may influence the effectiveness of EU budget expenditure, measured by the level of regional inequalities. The analysis starts by focusing on individuals’ attitudes towards income from their own effort and income which is derived from other people’s effort, having in mind that individual actions depend on their attitudes. The next step establishes the link between the income from other people’s effort with the re-distributive dimension of the EU budget, considering that different attitudes among individuals in the EU could lead to significant differences in effectiveness of this redistributive policy among European regions and, consequently, diverse regional inequalities. Empirical research uses data for 27 EU countries observed over two waves of European Value Surveys: 1999-2000 (Wave 1 and 2008–2009 (Wave 2. The results indicate a significant role of social attitudes for regional inequalities, which raises the question of the appropriateness of simplification and uniform regional policy instruments in solving EU regional problems.

  20. Regional sinkhole susceptibility maps: The Latium Region case (central Italy) (United States)

    La Vigna, F.; Teoli, P.; Mazza, R.; Leoni, G.; Capelli, G.


    Several and frequent studies were internationally presented about landslide susceptibility, meanwhile in literature is missing a broad diffusion of studies regarding sinkhole susceptibility. That's why sinkhole recurrence depends on several geological conditions related to specific geological and hydrogeological context (sinkhole prone area) that vary case by case. Notwithstanding this regionalization problem of sinkhole recurrence, in the central Appenine sedimentary basins (Italy) a certain number of geological, geomorphologic and hydrogeological conditions (sinkhole predisposing issues) can be considered in common between the surveyed sinkholes. Eventually this could be compared with similar geological conditions and sinkhole occurrence in the rest of Italy or in other countries. In this case study is presented a probabilistic approach regarding the Latium Region deriving from the comparison between the regional sinkhole inventory realized during a precedent project and the dataset of the new Hydrogeological Map of Latium Region (scale 1:100.000). Indexed elements, chosen because associated to the majority of sinkhole phenomena, are: outcropping lithologies, water table depth, main faults (even if buried), hydrothermal springs, land use and the epicentres of recent earthquakes. These indexed elements were weighted and combined in a matrix which preliminary result is the sinkhole susceptibility map of Latium Region. When definitively validated, this approach could be suitable for local authorities to planning more targeted studies in major hazard areas.

The analysis of intra-regional disparities as part of the economic growth at the level of Region West starts off with the idea that each component county has a different landscape, which favored or inhibited their economic growth; in the same time, each component county has its own specific, which can be promoted through tourism, inducing in time a regional income, and respectively, a social-economic and cultural growth of less developed areas.

  2. Regional Aspects of New Industrialization

    Directory of Open Access Journals (Sweden)

    Yakov Petrovich Silin


    Full Text Available In the article, the authors substantiate the need to consider the regional economic and other conditions when carrying out various essential transformations in the national economy of the country. We have argued the importance of new industrialization for overcoming the technological lag of the country and its regions and for supporting the large-scale structural transformations. We have proved that the complex set of the interconnected concepts and the theories of macro- and microlevels may be the theoretical platform for the paradigm of new industrialization. These are the theory of economic growth, the theory of the modernization of the economy, the theory of the change of technological ways during the industrial revolutions, theories of innovative development, developments in the field of the institutional theory. The authors have shown that the transition to new industrialization is the fundamental historical pattern for the majority of the countries of the world, including industrially developed ones. The purpose of the article is to identify the brightest tendencies and features of the development of the Ural macro-region in the years of market reforms as well as the definition of the strategic transformations in the context of the formation of new industrialization. The hypothesis of the research assumes that the revealed regional features of the Ural macroregion’s economic development are the prerequisites of its development as the centre of the modernization of the Russian economy. On the basis of the analysis of three groups of statistic data for the twenty-five year period of liberal and monetary reforms, the brightest tendencies and features of the development of the Ural macro-region are revealed. We have emphasized that the Ural macro-region has managed to keep its historically developed code — the industrial model of the economy, which have been developing for many decades. The authors have made a significant contribution of

  3. Slot Region Radiation Environment Models (United States)

    Sandberg, Ingmar; Daglis, Ioannis; Heynderickx, Daniel; Evans, Hugh; Nieminen, Petteri


    Herein we present the main characteristics and first results of the Slot Region Radiation Environment Models (SRREMs) project. The statistical models developed in SRREMs aim to address the variability of trapped electron and proton fluxes in the region between the inner and the outer electron radiation belt. The energetic charged particle fluxes in the slot region are highly dynamic and are known to vary by several orders of magnitude on both short and long timescales. During quiet times, the particle fluxes are much lower than those found at the peak of the inner and outer belts and the region is considered benign. During geospace magnetic storms, though, this region can fill with energetic particles as the peak of the outer belt is pushed Earthwards and the fluxes can increase drastically. There has been a renewed interest in the potential operation of commercial satellites in orbits that are at least partially contained within the Slot Region. Hence, there is a need to improve the current radiation belt models, most of which do not model the extreme variability of the slot region and instead provide long-term averages between the better-known low and medium Earth orbits (LEO and MEO). The statistical models developed in the SRREMs project are based on the analysis of a large volume of available data and on the construction of a virtual database of slot region particle fluxes. The analysis that we have followed retains the long-term temporal, spatial and spectral variations in electron and proton fluxes as well as the short-term enhancement events at altitudes and inclinations relevant for satellites in the slot region. A large number of datasets have been used for the construction, evaluation and inter-calibration of the SRREMs virtual dataset. Special emphasis has been given on the use and analysis of ESA Standard Radiation Environment Monitor (SREM) data from the units on-board PROBA-1, INTEGRAL, and GIOVE-B due to the sufficient spatial and long temporal

    A guide was prepared to allow a user to run the PNL long-range transport model, REGIONAL 1. REGIONAL 1 is a computer model set up to run atmospheric assessments on a regional basis. The model has the capability of being run in three modes for a single time period. The three modes are: (1) no deposition, (2) dry deposition, (3) wet and dry deposition. The guide provides the physical and mathematical basis used in the model for calculating transport, diffusion, and deposition for all three modes. Also the guide includes a program listing with an explanation of the listings and an example in the form of a short-term assessment for 48 hours. The purpose of the example is to allow a person who has past experience with programming and meteorology to operate the assessment model and compare his results with the guide results. This comparison will assure the user that the program is operating in a proper fashion.

  5. Regional Community and International Relations: the Volgograd Region Experience

    Directory of Open Access Journals (Sweden)

    Danakari Richard A.


    Full Text Available The article deals with the complex and controversial problems of the new regional communities’ formation and the impact of the interethnic relations sphere on them. The author notes that the processes of interaction between representatives of different cultures and civilizations, ethnic groups and religions have become increasingly controversial and tense in the context of continuous social dynamics. Similarly to the Russian society as a whole, regional communities are in a state of transitivity. They get transformed, they acquire new qualities such as multicasting and heterogeneity, multi-ethnicity and multi-confessionalism, fragmentarity and multiculturality. This fact increases the risks and uncertainties, problematizes future prospects. National non-governmental organizations are increasingly positioning themselves as civil society institutions at the present stage of social development at the regional level. They perform a difficult dual task: on the one hand, they ensure the preservation and development of history, native language, culture, ethnic traditions, and on the other hand, they work on the integration, on the common identity and the Russian nation formation. On the territory of the Volgograd region, largely due to the active cooperation of regional authorities and local authorities with national public associations, international and inter-confessional relations are stable. The basis of such activity is respect for history, native language, culture, tradition, religion, national dignity of all people in the region, regardless of their belonging to a certain ethnic group or religion. Over two decades of accumulated considerable experience of joint inter-ethnic dialogue and cooperation, provided tolerance and peace, harmony and mutual understanding between people of different ethnicities and religions in the country.

  6. Regional Transmission Projects: Finding Solutions

    Energy Technology Data Exchange (ETDEWEB)

    The Keystone Center


    The Keystone Center convened and facilitated a year-long Dialogue on "Regional Transmission Projects: Finding Solutions" to develop recommendations that will help address the difficult and contentious issues related to expansions of regional electric transmission systems that are needed for reliable and economic transmission of power within and across regions. This effort brought together a cross-section of affected stakeholders and thought leaders to address the problem with the collective wisdom of their experience and interests. Transmission owners sat at the table with consumer advocates and environmental organizations. Representatives from regional transmission organizations exchanged ideas with state and federal regulators. Generation developers explored common interests with public power suppliers. Together, the Dialogue participants developed consensus solutions about how to begin unraveling some of the more intractable issues surrounding identification of need, allocation of costs, and reaching consensus on siting issues that can frustrate the development of regional transmission infrastructure. The recommendations fall into three broad categories: 1. Recommendations on appropriate institutional arrangements and processes for achieving regional consensus on the need for new or expanded transmission infrastructure 2. Recommendations on the process for siting of transmission lines 3. Recommendations on the tools needed to support regional planning, cost allocation, and siting efforts.

  7. Regional desertification: A global synthesis (United States)

    Helldén, Ulf; Tottrup, Christian


    The paper presents results on the use of NOAA AVHRR data for desertification monitoring on a regional-global level. It is based on processing of the GIMMS 8 km global NDVI data set. Time series of annually integrated and standardized annual NDVI anomalies were generated and compared with a corresponding rainfall data set (1981-2003). The regions studied include the Mediterranean basin, the Sahel from the Atlantic to the Red Sea, major parts of the drylands of Southern Africa, China-Mongolia and the drylands of South America, i.e. important parts of the desertification prone drylands of the world. It is concluded that the suggested methodology is a robust and reliable way to assess and monitor vegetation trends and related desertification on a regional-global scale. A strong general relationship between NDVI and rainfall over time is demonstrated for considerable parts of the drylands. The results of performed trend analysis cannot be used to verify any systematic generic land degradation/desertification trend at the regional-global level. On the contrary, a "greening-up" seems to be evident over large regions.

  8. Obesity and Regional Immigrant Density. (United States)

    Emerson, Scott D; Carbert, Nicole S


    Canada has an increasingly large immigrant population. Areas of higher immigrant density, may relate to immigrants' health through reduced acculturation to Western foods, greater access to cultural foods, and/or promotion of salubrious values/practices. It is unclear, however, whether an association exists between Canada-wide regional immigrant density and obesity among immigrants. Thus, we examined whether regional immigrant density was related to obesity, among immigrants. Adult immigrant respondents (n = 15,595) to a national population-level health survey were merged with region-level immigrant density data. Multi-level logistic regression was used to model the odds of obesity associated with increased immigrant density. The prevalence of obesity among the analytic sample was 16%. Increasing regional immigrant density was associated with lower odds of obesity among minority immigrants and long-term white immigrants. Immigrant density at the region-level in Canada may be an important contextual factor to consider when examining obesity among immigrants.

  9. Regional profile, energy-impacted communities: Region VIII

    Energy Technology Data Exchange (ETDEWEB)



    This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

  19. Automatic thoracic body region localization (United States)

    Bai, PeiRui; Udupa, Jayaram K.; Tong, YuBing; Xie, ShiPeng; Torigian, Drew A.


    Radiological imaging and image interpretation for clinical decision making are mostly specific to each body region such as head & neck, thorax, abdomen, pelvis, and extremities. For automating image analysis and consistency of results, standardizing definitions of body regions and the various anatomic objects, tissue regions, and zones in them becomes essential. Assuming that a standardized definition of body regions is available, a fundamental early step needed in automated image and object analytics is to automatically trim the given image stack into image volumes exactly satisfying the body region definition. This paper presents a solution to this problem based on the concept of virtual landmarks and evaluates it on whole-body positron emission tomography/computed tomography (PET/CT) scans. The method first selects a (set of) reference object(s), segments it (them) roughly, and identifies virtual landmarks for the object(s). The geometric relationship between these landmarks and the boundary locations of body regions in the craniocaudal direction is then learned through a neural network regressor, and the locations are predicted. Based on low-dose unenhanced CT images of 180 near whole-body PET/CT scans (which includes 34 whole-body PET/CT scans), the mean localization error for the boundaries of superior of thorax (TS) and inferior of thorax (TI), expressed as number of slices (slice spacing ≍ 4mm)), and using either the skeleton or the pleural spaces as reference objects, is found to be 3,2 (using skeleton) and 3, 5 (using pleural spaces) respectively, or in mm 13, 10 mm (using skeleton) and 10.5, 20 mm (using pleural spaces), respectively. Improvements of this performance via optimal selection of objects and virtual landmarks and other object analytics applications are currently being pursued. and the skeleton and pleural spaces used as a reference objects

The article focuses on the results of an empirical study of the levels and characteristics of competence in social facilitation, which is here understood as the ability to apply certain knowledge and systems of skills and as a success rate of actions based on experience in improving the conditions of social development. The study was conducted in the Kaliningrad region in 2012—2013. The data was obtained through a survey of 400 respondents using the authors’ methodology encompassing eight basic elements of competence and a structured interview aimed at a better understanding of the subject of the study and attitudes towards it. The data is compared against the results of a similar study in two regions of central Russia with similar conditions. The results suggest a disharmonic and inconsistent structure of competence in social facilitation, low motivation for social activity in youth, and a narrow range of ideas about possible areas of personal activities in the current conditions. Gender differences are identified in the level and structure of competence. The authors believe that certain differences in competence components identified through mathematical methods are determined by the geographical characteristics of the Kaliningrad region — its exclave nature, a relatively small territory, and proximity to the EU countries. It is stressed that the regional conditions affecting motivation, forms and areas of activities, and structure of experience should be taken into account in selecting means and methods of organising youth activities. They can also serve as a basis for the regional youth policy.

  2. Geospatial Absorption and Regional Effects

    Directory of Open Access Journals (Sweden)



    Full Text Available The geospatial absorptions are characterized by a specific complexity both in content and in their phenomenological and spatial manifestation fields. Such processes are differentiated according to their specificity to pre-absorption, absorption or post-absorption. The mechanisms that contribute to absorption are extremely numerous: aggregation, extension, diffusion, substitution, resistivity (resilience, stratification, borrowings, etc. Between these mechanisms frequent relations are established determining an amplification of the process and of its regional effects. The installation of the geographic osmosis phenomenon in a given territory (a place for example leads to a homogenization of the geospatial state and to the installation of the regional homogeneity.

  4. Multimodal analgesia and regional anaesthesia. (United States)

    Tornero Tornero, C; Fernández Rodríguez, L E; Orduña Valls, J

    Multimodal analgesia provides quality analgesia, with fewer side effects due to the use of combined analgesics or analgesic techniques. Regional anaesthesia plays a fundamental role in achieving this goal. The different techniques of regional anaesthesia that include both peripheral and central blocks in either a single dose or in continuous infusion help to modulate the nociceptive stimuli that access the central level. The emergence of the ultrasound as an effective system to perform regional anaesthesia techniques has allowed the development of new regional anaesthesia techniques that formerly could not be carried out since only neurostimulation or skin references were used. It is essential to take into account that even with effective blocking it is advisable to associate other drugs by other routes, in this way we will be able to reduce the required doses individually and attempt to achieve a synergistic, not purely additive, effect.

    Bogdan Włodarczyk


    Full Text Available In the process of strategic planning the strategy of development as well as applications realizing it are formulated. Planning is the basis for preparing and taking decisions referring to principles, trends and the pace of far-reaching development. Elaboration of the strategy of regional development management is the undertaking of large scale complexity. It comprises decisions referring to development perspectives, formulating purposes and determining (choice the methods of their realization, analysis of social and political conditions, collecting and processing the information. Conditioning of defining the strategy has a versatile character. None of the above-mentioned areas can be regarded as less important. The purpose of this study is to attempt to identify basic problems of forming the strategy of regional development management. The study contains a brief description of planning regional development on the basis of the literature of the subject, and then empirical verification of the accepted hypothesis. Considerations and based upon them conclusions can be useful in working out the strategy of regional development management.

  6. Biocapacity optimization in regional planning (United States)

    Guo, Jianjun; Yue, Dongxia; Li, Kai; Hui, Cang


    Ecological overshoot has been accelerating across the globe. Optimizing biocapacity has become a key to resolve the overshoot of ecological demand in regional sustainable development. However, most literature has focused on reducing ecological footprint but ignores the potential of spatial optimization of biocapacity through regional planning of land use. Here we develop a spatial probability model and present four scenarios for optimizing biocapacity of a river basin in Northwest China. The potential of enhanced biocapacity and its effects on ecological overshoot and water consumption in the region were explored. Two scenarios with no restrictions on croplands and water use reduced the overshoot by 29 to 53%, and another two scenarios which do not allow croplands and water use to increase worsened the overshoot by 11 to 15%. More spatially flexible transition rules of land use led to higher magnitude of change after optimization. However, biocapacity optimization required a large amount of additional water resources, casting considerable pressure on the already water-scarce socio-ecological system. Our results highlight the potential for policy makers to manage/optimize regional land use which addresses ecological overshoot. Investigation on the feasibility of such spatial optimization complies with the forward-looking policies for sustainable development and deserves further attention.

  18. Molecular Regionalization of the Diencephalon

    Directory of Open Access Journals (Sweden)

    Almudena eMartinez-Ferre


    Full Text Available The anatomic complexity of the diencephalon depends on precise molecular and cellular regulative mechanisms orchestrated by regional morphogenetic organizers at the neural tube stage. In the diencephalon, like in other neural tube regions, dorsal and ventral signals codify positional information to specify ventro-dorsal regionalization. Retinoic acid, Fgf8, BMPs and Wnts signals are the molecular factors acting upon the diencephalic epithelium to specify dorsal structures, while Shh is the main ventralizing signal. A central diencephalic organizer, the zona limitans intrathalamica (ZLI, appears after neurulation in the central diencephalic alar plate, establishing additional antero-posterior positional information inside diencephalic alar plate. Based on Shh expression, the ZLI acts as a morphogenetic center, which cooperates with other signals in thalamic specification and pattering in the alar plate of diencephalon. Indeed, Shh is expressed first in the basal plate extending dorsally through the ZLI epithelium as the development proceeds. Despite the importance of ZLI in diencephalic morphogenesis the mechanisms that regulate its development remain incompletely understood. Actually, controversial interpretations in different experimental models have been proposed. That is, experimental results have suggested that (i the juxtaposition of the molecularly heterogeneous neuroepithelial areas, (ii cell reorganization in the epithelium and/or (iii planar and vertical inductions in the neural epithelium, are required for ZLI specification and development. We will review some experimental data to approach the study of the molecular regulation of diencephalic regionalization, with special interest in the cellular mechanisms underlying planar inductions.

    Full Text Available Sustainable development of administrative-territorial units (ATU refers to the main directions of Russian Federation state policy to ensure the security of the national economy to meet the vital needs of people and the preservation of such a possibility for the future generations. The article describes and analyzes the factors that have the most significant impact on the level of ATE development. The dynamics of the gross output of agriculture in Russia and its critical evaluation are presents. It was revealed that the development of the region is the basis of the national economy security. At present, the concept of “sustainable development” in Russia is relevant and the role of regions in the sustainable development of the Russian Federation is constantly increasing. Stability of self-financing of the regional economy is achieved through conducting effective fiscal, financial, credit, tax and price policy, establishment of equal inter-budgetary relations with the federal center, the development of the securities market, increasing the volume of exports. Conducted research allowed: to identify the main factors influencing the sustainable development of Russia regions. The reasons for the backlog of economy of the Smolensk region of the nationwide growth rate and direction of their elimination are examined. Formation of the forecast of domestic agriculture development in the period up to 2020 should be based on the priority position of the industry in the agricultural sector, which is determined by its decisive role in meeting the population’s needs for basic food products. Prospective volumes of production of major agricultural products are based on the need to meet the challenges provided by the Russian Federation Government Decree.

  6. Algorithms for Labeling Focus Regions. (United States)

    Fink, M; Haunert, Jan-Henrik; Schulz, A; Spoerhase, J; Wolff, A


    In this paper, we investigate the problem of labeling point sites in focus regions of maps or diagrams. This problem occurs, for example, when the user of a mapping service wants to see the names of restaurants or other POIs in a crowded downtown area but keep the overview over a larger area. Our approach is to place the labels at the boundary of the focus region and connect each site with its label by a linear connection, which is called a leader. In this way, we move labels from the focus region to the less valuable context region surrounding it. In order to make the leader layout well readable, we present algorithms that rule out crossings between leaders and optimize other characteristics such as total leader length and distance between labels. This yields a new variant of the boundary labeling problem, which has been studied in the literature. Other than in traditional boundary labeling, where leaders are usually schematized polylines, we focus on leaders that are either straight-line segments or Bezier curves. Further, we present algorithms that, given the sites, find a position of the focus region that optimizes the above characteristics. We also consider a variant of the problem where we have more sites than space for labels. In this situation, we assume that the sites are prioritized by the user. Alternatively, we take a new facility-location perspective which yields a clustering of the sites. We label one representative of each cluster. If the user wishes, we apply our approach to the sites within a cluster, giving details on demand.

  7. First regional CSM program planned. (United States)


    6 countries in the English-speaking Caribbean (Antigua, Barbados, Dominica, St. Kitts/Nevis, St. Lucia, and St. Vincent) are scheduled to form the 1st regional contraceptive social marketing program. The program will be under the auspices of the Barbados Family Planning Association. By combining resources, contraceptive social marketing should be able to effectively augment family planning activities in smaller countries where individual programs wuld be too costly. The regional program will also determine whether program elements from 1 country in a region are relevant in other countries. The Caribbean region as a whole has experienced a general decline in both crude birth rates and fertility rates during the past 15 years; however, adolescent fertility rates remain high and an average of 46% of the populations of Caribbean countries are under 15 years of age. Although heavy emigration has traditionally curbed population increases, new restrictive immigration laws are expected. Further increases in the working age population will contribute to already high unemployment rates and hinder economic development. The 6 countries selected for the social marketing program are receptive to innovative family planning approaches and have the basic marketing infrastructure required. Community-based distribution programs already in operation in these countries distribute condoms, oral contraceptives, and barrier methods. The success of these programs has plateaued, and there is a need for delivery systems capable of reaching broader segments of the population. The social marketing program will be phased in to ensure local acceptance among national leaders and consumers. The regional program hopes to borrow elements from Jamaica's contraceptive social marketing program to avoid the costs involved in starting a program from scratch. A major innovation will be the use of mass media advertising for contraceptives.

  13. EURO-CORDEX regional climate models: Performance over Mediterranean region (United States)

    Stilinović, Tomislav; Güttler, Ivan; Srnec, Lidija; Branković, Čedo


    Regional climate models (RCMs) are high-resolution version of a global climate models (GCMs) designed to achieve simulations at horizontal resolutions relevant for human activities on local and regional spatial scales, and to simulate relevant processes in historical and potential future climate conditions. In this study, a set of experiments the EURO-CORDEX simulations are evaluated over the Mediterranean region. All simulations were made at the two horizontal resolutions (50 km and 12.5 km) and compared with gridded pan-European gridded dataset E-OBSv11 at the regular 0.25°×0.25° grid for the two periods (1989-2008 for the ERA-Interim-driven ensemble of simulations; 1971-2000 for the GCMs-driven ensemble of simulations). We will evaluate the impacts of (1) the boundary conditions, (2) different horizontal resolutions (0.44°/50 km vs. 0.11°/12.5 km), and (3) the impact of convective parametrization on systematic errors, specialy in case of the RegCM4 model extensively used at DHMZ. For each simulation commonly used evaluation metrics are applied. They include: (1) spatially-averaged differences between RCMs and observations, (2) the spatial 95 th percentiles of simulated and observed temperature and precipitation, (3) spatial correlation coefficients between models and observations, (4) the ratio of spatial standard deviations between simulated and observed fields, and (5) the Spearman rank correlations between simulated and observed time-series of spatially-averaged temperature and precipitation. As commonly found in other studies, the total precipitation in RCM simulations is often overestimated and spatial correlations are noticeably lower than for temperature. The results highlight that, the RegCM4 is able to capture the (observed) spatial variability of the Mediterranean temperature climate. This is indicated by high spatial correlations with values larger than 0.9 and values of normalized standard deviation below 1 for Mediterranean region. The results

    The purpose of this study was to present the clinical features of a case series of osteomas in the craniofacial region and to compare them with those described in the dental literatures. A retrospective study of 18 patients diagnosed with osteomas in the craniofacial region was performed. The age, gender, location, symptoms, and the radiological findings were recorded. There were 13 women and 5 men from 18 years to 69 years of age (mean age, 42{+-}27 years). Fourteen osteomas were found in the mandible (78%), two in frontal sinus, one in sphenoid bone, and one in maxilla. Osteomas are benign tumors composed of mature compact bone or cancellous bone. They are essentially restricted to the craniofacial skeleton and rarely, if ever, are diagnosed in other bones.

    Full Text Available This paper advances the analysis of regional income convergence inColombia, through the use of the income data recently estimated for the departments,the main subnational political units. The results show a polarization process betweenBogotá and the rest of the departments. The preponderance of Bogotá during the periodanalyzed is also discussed: its per capita income is more than double that of thenational average, and more than eight times the per capita income of the poorest department,Chocó. Persistence in the departmental per capita income ranking is observed:Bogotá is always ahead, while the departments in the periphery are in the last places.The findings lead to the conclusion that it is necessary to design policies to correctthe significant disparities in per capita income between Colombian regions.

  19. Marine cloud brightening: regional applications (United States)

    Latham, John; Gadian, Alan; Fournier, Jim; Parkes, Ben; Wadhams, Peter; Chen, Jack


    The general principle behind the marine cloud brightening (MCB) climate engineering technique is that seeding marine stratocumulus clouds with substantial concentrations of roughly monodisperse sub-micrometre-sized seawater particles might significantly enhance cloud albedo and longevity, thereby producing a cooling effect. This paper is concerned with preliminary studies of the possible beneficial application of MCB to three regional issues: (1) recovery of polar ice loss, (2) weakening of developing hurricanes and (3) elimination or reduction of coral bleaching. The primary focus is on Item 1. We focus discussion herein on advantages associated with engaging in limited-area seeding, regional effects rather than global; and the levels of seeding that may be required to address changing current and near-term conditions in the Arctic. We also mention the possibility that MCB might be capable of producing a localized cooling to help stabilize the West Antarctic Ice Sheet. PMID:25404682

  20. Collision region of the ISR

    CERN Multimedia


    This is a collision region from the world’s first proton collider, the Intersecting Storage Rings. The ISR was used at CERN from 1971-84 to study proton-proton collisions at the highest energy then available (60GeV). When operational, ISR collision regions were surrounded by detectors as shown in the photo. In 1972, the surprising discovery of fragments flying out sideways from head-on proton-proton collisions was the first evidence of quark-quark scattering inside the colliding protons . This was similar to Rutherford’s observation in 1911 of alpha particles scattering off the tiny nucleus inside atoms of gold. The ISR beamtubes had to be as empty as outer space, a vacuum 100 000 times better than other CERN machines at the time.

    Saadettin Dagistan


    Full Text Available Regional odontodysplasia (RO is a rare developmental dental anomaly with an unknown etiology. It is more often seen in girls than boys. Treatment of RO depends on the individual case. The aims of treatment should include aiding mastication and speech, improving aesthetics, reducing the psychological impact of the anomaly, allowing normal jaw growth and development, and if possible protection of any erupted teeth which are affected. We present a rare case of RO together with the treatment modality undertaken.

    Kenneth J. Nemeth


    The Southeast Regional Carbon Sequestration Partnership's (SECARB) Phase I program focused on promoting the development of a framework and infrastructure necessary for the validation and commercial deployment of carbon sequestration technologies. The SECARB program, and its subsequent phases, directly support the Global Climate Change Initiative's goal of reducing greenhouse gas intensity by 18 percent by the year 2012. Work during the project's two-year period was conducted within a ''Task Responsibility Matrix''. The SECARB team was successful in accomplishing its tasks to define the geographic boundaries of the region; characterize the region; identify and address issues for technology deployment; develop public involvement and education mechanisms; identify the most promising capture, sequestration, and transport options; and prepare action plans for implementation and technology validation activity. Milestones accomplished during Phase I of the project are listed below: (1) Completed preliminary identification of geographic boundaries for the study (FY04, Quarter 1); (2) Completed initial inventory of major sources and sinks for the region (FY04, Quarter 2); (3) Completed initial development of plans for GIS (FY04, Quarter 3); (4) Completed preliminary action plan and assessment for overcoming public perception issues (FY04, Quarter 4); (5) Assessed safety, regulatory and permitting issues (FY05, Quarter 1); (6) Finalized inventory of major sources/sinks and refined GIS algorithms (FY05, Quarter 2); (7) Refined public involvement and education mechanisms in support of technology development options (FY05, Quarter 3); and (8) Identified the most promising capture, sequestration and transport options and prepared action plans (FY05, Quarter 4).

  11. Comparison of regional screening methods

    Energy Technology Data Exchange (ETDEWEB)

    Hobbs, B.F.; Rowe, M.D.


    This report describes results of tests of different regional screening methods applied to data from western Maryland and the western United States. The purpose of these tests was to determine whether or not different regional screening methods produce different results, and to obtain some understanding of the nature of any differences found. Methods tested include Exclusionary Screening, Weighting Summation, Power Law, and Decision Analysis; weighting methods used include Categorization, Rating, Metfessel Allocation, Indifference Tradeoff, Churchman-Ackoff, and Decision Analysis. Results show that different methods do, indeed, produce different results, and that choice of decision rule is most important to results. Exclusionary Screening, in particular, can force decision tradeoffs that decision makers would not make were they to evaluate them directly. Nevertheless, differences in regional screening results do not necessarily mean differences in quality of the final site decision. The final result can depend on the skill with which the stages of the siting process following screening are conducted. The function of screening is to ease the task in those following stages by selecting candidate areas having high probability of containing suitable candidate sites. 32 refs., 32 figs., 43 tabs.

  13. Behcet's syndrome in nonendemic regions. (United States)

    Leccese, Pietro; Yazici, Yusuf; Olivieri, Ignazio


    Behcet's syndrome is more common in certain geographic regions, however, can be seen outside of these areas and need to be included in the differential diagnosis of many patients, as it has overlapping features with many rheumatologic conditions. Especially in regions with immigrant populations, there seem to be similarities to originating countries in Behcet's prevalence, but the syndrome is not limited to those from certain backgrounds and can be seen in others also. There is emerging evidence that even though the prevalence of Behcet's may be similar to that of endemic areas, in nonendemic regions the condition may be less severe, suggesting potential environment agents in determining the severity of the disease. In addition, women seem to be overrepresented in nonendemic areas and may explain part of the reason for less severe symptoms, as Behcet's tends to be more severe in men. The somewhat different presentation of Behcet's syndrome in nonendemic areas needs to be considered when thinking about Behcet's in the differential diagnosis of patients. Research into potentially less severe form of the disease in nonendemic areas may provide new clues to the pathogenesis of this condition.

  14. Developing a Regional Recovery Framework

    Lesperance, Ann M.; Olson, Jarrod; Stein, Steven L.; Clark, Rebecca; Kelly, Heather; Sheline, Jim; Tietje, Grant; Williamson, Mark; Woodcock, Jody


    Abstract A biological attack would present an unprecedented challenge for local, state, and federal agencies; the military; the private sector; and individuals on many fronts ranging from vaccination and treatment to prioritization of cleanup actions to waste disposal. To prepare the Seattle region to recover from a biological attack, the Seattle Urban Area Security Initiative (UASI) partners collaborated with military and federal agencies to develop a Regional Recovery Framework for a Biological Attack in the Seattle Urban Area. The goal was to reduce the time and resources required to recover and restore wide urban areas, military installations, and other critical infrastructure following a biological incident by providing a coordinated systems approach. Based on discussions in small workshops, tabletop exercises, and interviews with emergency response agency staff, the partners identified concepts of operation for various areas to address critical issues the region will face as recovery progresses. Key to this recovery is the recovery of the economy. Although the Framework is specific to a catastrophic, wide-area biological attack using anthrax, it was designed to be flexible and scalable so it could also serve as the recovery framework for an all-hazards approach. The Framework also served to coalesce policy questions that must be addressed for long-term recovery. These questions cover such areas as safety and health, security, financial management, waste management, legal issues, and economic development.

  15. Quantifying China's regional economic complexity (United States)

    Gao, Jian; Zhou, Tao


    China has experienced an outstanding economic expansion during the past decades, however, literature on non-monetary metrics that reveal the status of China's regional economic development are still lacking. In this paper, we fill this gap by quantifying the economic complexity of China's provinces through analyzing 25 years' firm data. First, we estimate the regional economic complexity index (ECI), and show that the overall time evolution of provinces' ECI is relatively stable and slow. Then, after linking ECI to the economic development and the income inequality, we find that the explanatory power of ECI is positive for the former but negative for the latter. Next, we compare different measures of economic diversity and explore their relationships with monetary macroeconomic indicators. Results show that the ECI index and the non-linear iteration based Fitness index are comparative, and they both have stronger explanatory power than other benchmark measures. Further multivariate regressions suggest the robustness of our results after controlling other socioeconomic factors. Our work moves forward a step towards better understanding China's regional economic development and non-monetary macroeconomic indicators.

  17. Regional air pollution over Malaysia (United States)

    Krysztofiak, G.; Catoire, V.; Dorf, M.; Grossmann, K.; Hamer, P. D.; Marécal, V.; Reiter, A.; Schlager, H.; Eckhardt, S.; Jurkat, T.; Oram, D.; Quack, B.; Atlas, E.; Pfeilsticker, K.


    During the SHIVA (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere) campaign in Nov. and Dec. 2011 a number of polluted air masses were observed in the marine and terrestrial boundary layer (0 - 2 km) and in the free troposphere (2 - 12 km) over Borneo/Malaysia. The measurements include isoprene, CO, CO2, CH4, N2O, NO2, SO2 as primary pollutants, O3 and HCHO as secondary pollutants, and meteorological parameters. This set of trace gases can be used to fingerprint different sources of local and regional air pollution (e.g., biomass burning and fossil fuel burning, gas flaring on oil rigs, emission of ships and from urban areas, volcanic emissions, and biogenic emissions). Individual sources and location can be identified when the measurements are combined with a nested-grid regional scale chemical and meteorological model and lagrangian particle dispersion model (e.g., CCATT-BRAMS and FLEXPART). In the case of the former, emission inventories of the primary pollutants provide the basis for the trace gas simulations. In this region, the anthropogenic influence on air pollution seems to dominate over natural causes. For example, CO2 and CH4 often show strong correlations with CO, suggesting biomass burning or urban fossil fuel combustion dominates the combustion sources. The study of the CO/CO2 and CH4/CO ratios can help separate anthropogenic combustion from biomass burning pollution sources. In addition, these ratios can be used as a measure of combustion efficiency to help place the type of biomass burning particular to this region within the wider context of fire types found globally. On several occasions, CH4 enhancements are observed near the ocean surface, which are not directly correlated with CO enhancements thus indicating a non-combustion-related CH4 source. Positive correlations between SO2 and CO show the anthropogenic influence of oil rigs located in the South China Sea. Furthermore, SO2 enhancements are observed without any increase in CO

    Energy supply companies and industrial plants are likely to face new situations due to, for example, the introduction of new energy legislation, increased fuel prices and increased environmental awareness. These new prerequisites provide companies with new challenges but also new possibilities from which to benefit. Increased energy efficiency within companies and increased cooperation between different operators are two alternatives to meet the new conditions. A region characterized by a high density of energy-intensive processes is used in this study to find the economic potential of connecting three industrial plants and four energy companies, within three local district heating systems, to a regional heat market, in which different operators provide heat to a joint district heating grid. Also, different investment alternatives are studied. The results show that the economical potential for a heat market amounts to between 5 and 26 million EUR/year with payback times ranging from two to eleven years. However, the investment costs and the net benefit for the total system need to be allotted to the different operators, as they benefit economically to different extents from the introduction of a heat market. It is also shown that the emissions of CO{sub 2} from the joint system would decrease compared to separate operation of the systems. However, the valuation of CO{sub 2} emissions from electricity production is important as the difference of emitted CO{sub 2} between the accounting methods exceeds 650 kton/year for some scenarios.

  2. Balancing regional sea level budgets (United States)

    Leuliette, E. W.; Miller, L.; Tamisiea, M. E.


    Balancing the sea-level budget is critical to understanding recent and future climate change as well as balancing Earth's energy budget and water budget. During the last decade, advancements in the ocean observing system — satellite altimeters, hydrographic profiling floats, and space-based gravity missions — have allowed the global mean sea level budget to?be assessed with unprecedented accuracy from direct, rather than inferred, estimates. In particular, several recent studies have used the sea-level budget to bound the rate of deep ocean warming [e.g. Llovel et al. 2014]. On a monthly basis, the sum of the steric component estimated from Argo and the ocean mass (barostatic) component from GRACE agree total sea level from Jason within the estimated uncertainties with the residual difference having an r.m.s. of less than 2 mm [Leuliette 2014]. Direct measurements of ocean warming above 2000 m depth during January 2005 and July 2015 explain about one-third of the observed annual rate of global mean sea-level rise. Extending the understanding of the sea-level budget from global mean sea level to regional patterns of sea level change is crucial for identifying regional differences in recent sea level change. The local sea-level budget can be used to identify any systematic errors in the global ocean observing system. Using the residuals from closing the sea level budget, we demonstrate that systematic regional errors remain, in part due to Argo sampling. We also show the effect of applying revised geocentric pole-tide corrections for GRACE [Wahr et al. 2015] and altimetry [Desai et al., 2015].

  3. Regional energy integration in Africa

    Energy Technology Data Exchange (ETDEWEB)



    This report is the first publication produced within the framework of the WEC's Africa Regional Action Plan as part of the 2005-2007 Work Programme. Presently, over 80% of the total energy consumption in Africa is based on traditional biomass used mostly for cooking. This lack of access to modern energy is holding back economic and social development for 1.6 billion people around the world. The situation is particularly grave in sub-Sahara Africa where over 80% of the population lives in rural areas and the average electrification rate is less than 5%. At least 50 million new connections are needed to provide electricity to supply the non-connected areas in Africa. The over 700 million potential customers represented by these new connections provide a major business opportunity. It is now widely recognised that development assistance, bilateral aid, multilateral financing institutions, a multitude of international aid agencies, NGOs and others have failed to make a significant difference. A new approach is required, otherwise the number of people without access to electricity will continue to grow, and none of the Millennium Development Goals set by the United Nations will be achieved. This regional report highlights key factors that affect cooperative energy projects. The geopolitical context, investment climate and appropriate regulation are just as important as the institutional and technical capacity required to execute many of these projects. The report identifies four key benefits of regional integration: improved security of supply and accessibility; increased economic efficiency; enhanced environmental quality and broader development of renewable resources.

    Golightly, M.; Raben, V.; Weyland, M.


    The Solar Active Region Display System (SARDS) is a client-server application that automatically collects a wide range of solar data and displays it in a format easy for users to assimilate and interpret. Users can rapidly identify active regions of interest or concern from color-coded indicators that visually summarize each region's size, magnetic configuration, recent growth history, and recent flare and CME production. The active region information can be overlaid onto solar maps, multiple solar images, and solar difference images in orthographic, Mercator or cylindrical equidistant projections. Near real-time graphs display the GOES soft and hard x-ray flux, flare events, and daily F10.7 value as a function of time; color-coded indicators show current trends in soft x-ray flux, flare temperature, daily F10.7 flux, and x-ray flare occurrence. Through a separate window up to 4 real-time or static graphs can simultaneously display values of KP, AP, daily F10.7 flux, GOES soft and hard x-ray flux, GOES >10 and >100 MeV proton flux, and Thule neutron monitor count rate. Climatologic displays use color-valued cells to show F10.7 and AP values as a function of Carrington/Bartel's rotation sequences - this format allows users to detect recurrent patterns in solar and geomagnetic activity as well as variations in activity levels over multiple solar cycles. Users can customize many of the display and graph features; all displays can be printed or copied to the system's clipboard for "pasting" into other applications. The system obtains and stores space weather data and images from sources such as the NOAA Space Environment Center, NOAA National Geophysical Data Center, the joint ESA/NASA SOHO spacecraft, and the Kitt Peak National Solar Observatory, and can be extended to include other data series and image sources. Data and images retrieved from the system's database are converted to XML and transported from a central server using HTTP and SOAP protocols, allowing

  12. Surface compositions in the Aristarchus Region: Implications for regional stratigraphy (United States)

    Hawke, H. R.; Lucey, P. G.; Mccord, T. B.; Pieters, C. M.; Head, J. W.


    Near infrared reflectance spectra for the Aristachus region, obtained using the 2.2m UH telescope at the Mauna Kea Observatory, were reduced and analyzed. The spectra obtained for the central peak, southern floor, southwestern wall, eastern wall, and northwestern wall of Aristachus crater exhibit shallow continuum slopes, relatively strong feldspar bands, pyroxene bands stronger than those typically seen in the spectra of fresh higland features, and pyroxene band centers near l micrometer suggesting the dominance of Ca rich clinopyroxene. The spectrum of the south rim of Aristachus is quite distinct from those of other crater units. The position of Aristrchus on the plateau/mare boundary raises questions concerning compositional variations in crater ejects deposits.

  15. Talisman in the orofacial region. (United States)

    Loh, F C; Yeo, J F


    Among the various traditional beliefs and practices of the peoples of the Southeast Asia region is the practice of inserting talismans under the skin in various parts of the human body. In the orofacial region, these talismans (also called charm needles or charm pins) are also seen, usually as incidental radiographic findings. These talismans are believed to enhance the beauty of the wearers, as well as to provide protection to the wearers against harm. It is also believed that they could help the wearer obtain favorable business deals inasmuch as they are believed to have a "spell-like" influence on the business counterparts. In the present series, 67% of the patients are female and 66% of them are Muslim. Very little is known about the possible ill effects of these talismans because there is no report of these radiographic findings in major dental journals. In the present series of 12 cases representing a total of 65 talismans, only one talisman was surgically removed. We believe that generally no definitive treatment is required. However, we believe that the existence of these talismans should be made known so that they will not be misdiagnosed and mismanaged.

  16. Regional solid waste management study

    Energy Technology Data Exchange (ETDEWEB)


    In 1990, the Lower Savannah Council of Governments (LSCOG) began dialogue with the United States Department of Energy (DOE) regarding possibilities for cooperation and coordination of solid waste management practices among the local governments and the Savannah River Site. The Department of Energy eventually awarded a grant to the Lower Savannah Council of Governments for the development of a study, which was initiated on March 5, 1992. After careful analysis of the region`s solid waste needs, this study indicates a network approach to solid waste management to be the most viable. The network involves the following major components: (1) Rural Collection Centers, designed to provide convenience to rural citizens, while allowing some degree of participation in recycling; (2) Rural Drop-Off Centers, designed to give a greater level of education and recycling activity; (3) Inert landfills and composting centers, designed to reduce volumes going into municipal (Subtitle D) landfills and produce useable products from yard waste; (4) Transfer Stations, ultimate landfill disposal; (5) Materials Recovery Facilities, designed to separate recyclables into useable and sellable units, and (6) Subtitle D landfill for burial of all solid waste not treated through previous means.

The of this research was to show the number of drug abusers in Prishtina region, the type of drugs used, the way of drug administration, then survey of the age, sex, marital status, residence of the drug abusers including their social status (employment, profession and economical status). During the surveyed period the number of hospitalized drug abusers in Neuropsychiatry clinic was 39. 25.5% of them were hospitalized more than ones, with 367 stay days with average treatment period of 7.5 days. Average age of those hospitalized for the first time was 27.9 years of age. 64.1% of them were 25-34 years old. 97.4% of the hospitalized were male. 32 (82.1%) patient were from Prishtina, 5 from Ferizaj and 1 from F. Kosova and Kacanik. During the surveyed period there was no patient hospitalized from other cities of Prishtina Region (Besiana, Drenas, Kastriot, Lipjan, Shtime and Shterpc).

  18. Regionality – Language – Internet

    Directory of Open Access Journals (Sweden)

    Pásztor-Kicsi Mária


    Full Text Available The Internet has a strong influence on our daily communication and language use. Its continuous growing makes us face the world characterized by networks of connections that span multi-continental distances. The metaphor of global village seems to be not merely a futuristic theory, but pure reality. People can communicate worldwide with each other, reach all kinds of information to get up-to-date, as long as they respect the basic demand of globalization, which means the use of a common language (i.e. English. But this tendency hides a serious issue if we try to observe globalization from the aspect of local and regional cultures and languages, especially those in minority position. The study deals with the language use of the Hungarian minority in Vojvodina, with special focus on Netspeak and the regional features of language forms used on the Internet. It also analyses the attitudes of a group of students towards the influence of the Internet on speech and language. This part of the survey is based on questionnaires.

  19. Jalisco Regional Seismic Network (RESAJ) (United States)

    Nunez-Cornu, F. J.; Suarez Plascencia, C.; Escudero, C. R.; Gomez, A.


    Many societies and their economies endure the disastrous consequences of destructive earthquakes. The Jalisco region is exposing to this natural hazard. Scientific knowledge constitutes the only way to avoid or at least to mitigate the negative effects of such events. Accordingly the study of geological and geophysical causes; structural, kinematics and dynamic characteristics; and destructive effects of such events is indispensable. The main objective of this project is to developed capability to monitor and to analyze the potential destructive earthquakes along the Jalisco region. This network will allows us to study the Rivera plate and the Jalisco block seismicity. Ten earthquakes greater than 7.4 occurred in the last 160 years, including the largest Mexican earthquake (8.2) producing considerable damage in the area. During this project we installed 20 telemetric seismic stations and we plan to deploy up to 30. The stations are component by 24 bit A/D, 6 channels Quanterra Q330-6 DAS, Lennartz Triaxial 1Hz wide band seismometer, a triaxial accelerometer episensor Model FBA ES-T from Kinemetrics and solar power supply. The data is transmitted using freewave Ethernet radios or wireless internet links. All stations will transmit the data in to the central at Puerto Vallarta where all data is processed using Antelope system to localize and make preliminary evaluations of the events in almost real time and stored for future research. This network will produce high quality data enough to evaluate the eight previously identified seismic zones along Jalisco.

  20. [Epidemiological imaginary in Campania Region]. (United States)

    Greco, Pietro


    The interviews on the epidemiological imaginary, collected within the framework of the project Sebiorec,(1) clearly demonstrate that also in Campania, on the border between the provinces of Naples and Caserta - where the issue of waste and land devastation take forms that are unprecedented compared to any other part of Europe - there is a widespread, strong, sacrosanct demand of participation in environment and health management. The request of deliberative ecological democracy is pressing.(2) There is an urgent need to meet that plethora of rights emerging in the "knowledge society" and in the "risk society" that someone has called "rights for scientific citizenship."(3) This request of the population of Campania, net of local cultural specificity, it is quite similar to that of the people of any other region of Europe. The context in which this request of participation is expressed, however, is quite different. Not only and not just for that real or perceived social pre-modern and familist web that would replace a modern civil society in Campania and all across the Southern Italian regions, but also and especially for some structural causes that we here try to list. Campania is a unique region in Europe - in many ways different even from other regions of southern Italy - due to the conjunction of at least five factors, not independent from each other. 1) The presence of a widespread organized crime which, in many areas, metropolitan and non-metropolitan alike, and especially in the provinces of Naples and Caserta, is a sort of state against the State and has one of its main levers of power and a major source of its wealth in the illegal control of the territory, in its different dimensions (military, but also economic, social and even cultural). 2) A huge social and economic disintegration, exacerbated in the last twenty years by a process of deindustrialization (until the early nineties Naples was the fifth industrial city of Italy, today it is a desert where

  2. Cooperative monitoring of regional security agreements

    Energy Technology Data Exchange (ETDEWEB)

    Pregenzer, A.L.; Vannoni, M.; Biringer, K.L. [Sandia National Labs., Albuquerque, NM (United States). Nonproliferation and Arms Control Analysis Dept.


    This paper argues that cooperative monitoring plays a critical role in the implementation of regional security agreements and confidence building measures. A framework for developing cooperative monitoring options is proposed and several possibilities for relating bilateral and regional monitoring systems to international monitoring systems are discussed. Three bilateral or regional agreements are analyzed briefly to illustrate different possibilities. These examples illustrate that the relationship of regional or bilateral arms control or security agreements to international agreements depends on a number of factors: the overlap of provisions between regional and international agreements; the degree of interest in a regional agreement among the international community; efficiency in implementing the agreement; and numerous political considerations. Given the importance of regional security to the international community, regions should be encouraged to develop their own infrastructure for implementing regional arms control and other security agreements. A regional infrastructure need not preclude participation in an international regime. On the contrary, establishing regional institutions for arms control and nonproliferation could result in more proactive participation of regional parties in developing solutions for regional and international problems, thereby strengthening existing and future international regimes. Possible first steps for strengthening regional infrastructures are identified and potential technical requirements are discussed.

    The U.S. DOE Regional Test Center for Solar Technologies program was established to validate photovoltaic (PV) technologies installed in a range of different climates. The program is funded by the Energy Department's SunShot Initiative. The initiative seeks to make solar energy cost competitive with other forms of electricity by the end of the decade. Sandia National Laboratory currently manages four different sites across the country. The National Renewable Energy Laboratory manages a fifth site in Colorado. The entire PV portfolio currently includes 20 industry partners and almost 500 kW of installed systems. The program follows a defined process that outlines tasks, milestones, agreements, and deliverables. The process is broken out into four main parts: 1) planning and design, 2) installation, 3) operations, and 4) decommissioning. This operations manual defines the various elements of each part.

  5. Regional medical data mining system. (United States)

    Robu, Raul; Stoicu-Tivadar, Vasile


    This paper suggests a solution to acquire medical data from hospitals located in a region (addressing especially the DKMT Euroregion), and then perform data mining. The medical data from the hospital databases are exported in XML format, according to HL7 CDA standard. Afterwards, they are automatically centralized on a server in a database using web services calls. The data will be analyzed with the data mining tool WEKA. Data of interest are converted into ARFF format and loaded into WEKA. The next stage consists in preprocessing and analyzing the data based on the algorithms provided by WEKA, having as a goal several relevant medical conclusions. WEKA application interface has been improved to facilitate the process of performing predictions.

  6. Complex regional pain syndrome underdiagnosed. (United States)

    Quisel, Anna; Gill, James M; Witherell, Peter


    Complex regional pain syndrome (CRPS) type 1 may be diagnosed by history and physical exam with no further testing. Several different diagnostic criteria have undergone validity testing: the 1993 IASP criteria, Bruehl's criteria, and Veldman's criteria; there is no compelling reason to recommend 1 set of criteria over the others. Some cases of CRPS type 1 may be preventable. Some cases of CRPS type 1 in post-stroke upper extremity hemiplegia (also known as shoulder-hand syndrome) may be prevented by early inpatient rehabilitation and avoidance of shoulder trauma to the affected arm. Some cases of post-fracture CRPS type 1 may be prevented with 500 mg vitamin C daily started upon diagnosis of fracture and continued through healing.

    Eriksen, Jesper

    This paper provides an overview of Danish student to population ratios in post-primary education from 1982 to 2013. Using administrative register data I document a nationally increased share of enrolled students to population over the 32 years period. The increase followed a pattern of regional...... centralization where the shares of students rose significantly more in urban municipalities than non-urban municipalities. The highest shares of students as well as fastest increases were seen in the municipalities of the four largest cities, Copenhagen, Århus, Odense, and Aalborg. At the national level......, the increases in shares of students to population was driven by medium length and long tertiary as well as high school enrollment. The tertiary enrolled students, however, were unproportionally centred in the urban municipalities. Non-urban municipalities had relatively higher levels of high school...

  8. Regional differences in tropospheric ozone

    Energy Technology Data Exchange (ETDEWEB)

    Builtjes, P.; Esser, P. [TNO Inst. of Environmental Sciences, Energy Research and Process Innovation Apeldoorn (Netherlands)


    Analysis of ozone measurements over Europe, as well as model calculations indicate large differences in the relative importance of the phenomena controlling ozone over different areas in Europe. The ozone budget, consisting of chemistry, deposition and horizontal and vertical transport, shows differences due to differences in emission density and in dry deposition values, best exemplified by the land-sea effect. In this paper, some initial results will be presented of an analysis of regional differences, using the results of the 3-D Eulerian grid model LOTOS (Long Term Ozone Simulation) over 1994, based on the hourly O{sub 3} results of LOTOS on a grid scale of 1/2 deg. Latitude * 1 deg. Longitude. (au)

  9. Zoonoses in the Mediterranean region. (United States)

    Seimenis, Aristarco; Morelli, Daniela; Mantovani, Adriano


    The Mediterranean and Middle East Region (MME) is considered the most important area for the historical development and concentration of zoonoses. Besides the classical Mediterranean pattern, an urbanised pattern has emerged which is strongly influenced by globalisation. Both patterns co-exist and have many peculiarities affecting the life cycles of zoonoses and their social impact. The features of those zoonoses which are now most relevant in the MME (brucellosis, rabies, cystic echinococcosis, leishmaniasis, food-borne zoonoses) are discussed. Besides other relevant activities, the World Health Organization has established, since 1979, a specialised programme with a unit coordinating and managing activities: i.e. the Mediterranean Zoonoses Control Centre, operating from Athens, Greece.

  11. Carotid endarterectomy with regional anesthesia. (United States)

    Harbaugh, R E; Pikus, H J


    The senior author (REH) has changed his technique for performing carotid endarterectomy from the use of general anesthesia to the use of cervical block anesthesia. Because a randomized study was not performed, it is difficult to separate effects of increased surgical experience from those caused by a change in anesthetic regimen. Nonetheless, there has been a substantial decrease in complications, length of hospital stay, and costs concomitant with the change to regional anesthesia; we think there is a causal relationship. The use of cervical block anesthesia has practically eliminated the non-stroke-related complications associated with carotid endarterectomy in our practice. The technique for performing carotid endarterectomy under cervical block anesthesia is described in detail.

  12. Regional Priorities of Green Economy

    Directory of Open Access Journals (Sweden)

    Sergey Nikolayevich Bobylev


    Full Text Available The article is dedicated to transforming the economy of Russian regions to a green economy, which is an essential factor for the sustainable development. This is important not only for Russia but the whole world because our country has the great natural capital and provides important environmental services that support the planet biosphere. Based on the analysis of economic, social and ecological statistical data and Human Development Index (HDI we have shown that the development of Russian Federal Districts is very unbalanced and each Russian region has its own way to new economic model. For instance, it is necessary to increase the well-being in the North Caucasus Federal District, it is important to reach higher life expectancy at birth in the Siberian and the Far Eastern Districts. It is necessary to move from the «brown» economy to a green one by using the human capital (building a knowledge economy, by applying Best Available Technologies (Techniques, by investing in efficiency of use of natural resources and by increasing energy efficiency. The transition to a green economy will help to achieve social equity and the development of human potential; it helps to move from the exploitation of non-renewable natural capital to renewable human capital. All these socio-economic measures should give decoupling effect, make risks lower, reduce the exploitation of natural capital, stop the environmental degradation and prevent the ecological crisis. Transition to the green economic model has to be accompanied by new economic development indicators, which take into account social and environmental factors.

  13. Nuclear safety in crisis regions

    Energy Technology Data Exchange (ETDEWEB)

    Ustohalova, Veronika; Englert, Matthias


    The use of nuclear energy demands extensive institutional and material infrastructure upon a foundation of stable intrastate conditions and interstate relations. Conflicts can result in catastrophic accidents, either deliberately or unintentionally. If there are nuclear facilities located in a crisis region, the risk of a nuclear disaster is markedly heightened. This can be explained not only in terms of the strategic relevance of the energy supply in military conflicts, but also the increased accident risks and hazards arising from collateral damage, as well as the erosion of the safety culture and institutional control in crisis regions with a nuclear infrastructure. Even just the escalation of a political dispute or the persistence of low intensity conflicts can make it generally more difficult and complex to maintain nuclear safety, if intrastate safety mechanisms come under strain or even fail as a result. So far no instance of military escalation, past or present, has led to an accident in a civil nuclear facility. Nevertheless, questions are clearly raised about the vulnerability of nuclear facilities in crisis regions and the risks associated with this vulnerability. Despite the potentially far-reaching consequences, too little attention is currently being paid to the linkage between intra- and interstate conflicts and the safety of nuclear facilities in crisis regions. The aim of the research presented here was to explore this theme and, after laying the groundwork in this manner, to raise awareness among policy-makers and the wider public. In this context the escalation of conflicts in the Ukraine is a particular focus. The first part of the report begins with a systematic look at the link between crisis regions and/or conflicts and nuclear safety. The various impact pathways relating to nuclear facility safety and the associated risks are described in relation to potential hazards induced by crises and wars. A nuclear facility can itself become a theatre

  14. Congenital anomalies in Primorsky region. (United States)

    Kiku, P; Voronin, S; Golokhvast, K


    According to WHO hereditary diseases and congenital malformations contribute significantly to the health of population. Thus, the problems of epidemiology, clinical presentation, diagnosis and treatment of congenital abnormalities are of interest for many researchers [2]. In addition, the dynamic accounting for the incidence of congenital malformations and hereditary diseases allows the researchers to assess the ecological situation in the region [1]. The occurrence of congenital anomalies in the world varies; it depends heavily on how carefully the data is collected [4]. Multifactorial or polygenic diseases develop under the influence of environmental factors in the presence of defective genes. They can constitute up to 90% of all chronic pathology [2-5]. To determine the incidence of congenital anomalies under the influence of environmental factors. The study used the methodology of system evaluation of congenital anomalies incidence in Primorsky region, depending on bio-climatic and environmental conditions. The authors used health statistics for the period from 2000 to 2014, F.12 class for congenital abnormalities in adolescents and children that were compared in geographical and temporal aspects with environmental factors of 33 settlements in Primorsky region. The environment is represented by nature and climate (6 factor modules) and sanitation (7 factor modules) blocks of factors. When formalizing the information database of the environment a specially developed 10-point assessment scale was used. Statistical processing of the information was carried out using Pearson's chi-squared test and multiple regression method from SSPS application program package. The study found that over the 15-year period the level of congenital abnormalities in children increased by 27.5% and in adolescents - by 35.1%, and in 2014 it amounted to 1687.6 and 839.3 per 100 000 people, respectively. The predictive model shows a steady further growth of this pathology. The incidence

  15. Regional Development Planning in the Slovak Republic (United States)

    Rentková, Katarína


    Regional development is very closely related to a region and its competitive advantages which affect the competitiveness of the region. The regional development is influenced by many factors that act differently depending on the region. To ensure the effective and harmonized regional development, the systematic approach is needed. Every region is unique and differs from the other by the level of economic development, living standards of its inhabitants, unemployment rate and by employment possibilities. Regional policy is a strategic investment policy which focuses on all regions and cities in the European Union. The aim is to boost economic growth and to improve the quality of people’s lives. Solidarity is the main feature of the policy, because policy focuses on support for less developed regions. A fundamental aspect of regional development is to reduce disparities between the regions and cities. The paper focuses on the analysis of regional development of Slovakia. The intention is to follow the logical continuity of the article’s parts, the correctness and the adequacy of information and data. First part is focused on the definition of the regional policy and regional development. Important task is to identify the differences between European policies – regional, structural and cohesion policy. This section is prepared by using the analytical methods – the analysis, the casual and historical analysis. This part is based on literature review. The empirical part is based on statistics and secondary analysis which were aimed to analyse the regional development and effectiveness of its planning in the Slovak Republic. The question of this article is whether it is possible to plan the regional development by application of the plan for economic and social development, called the Municipal Development Plan.

  16. [Chromosomal variation in Chironomus plumosus L. (Diptera, Chironomidae) from populations of Bryansk region, Saratov region (Russia), and Gomel region (Belarus)]. (United States)

    Belyanina, S I


    Cytogenetic analysis was performed on samples of Chironomus plumosus L. (Diptera, Chironomidae) taken from waterbodies of various types in Bryansk region (Russia) and Gomel region (Belarus). Karyotypes of specimens taken from stream pools of the Volga were used as reference samples. The populations of Bryansk and Gomel regions (except for a population of Lake Strativa in Starodubskii district, Bryansk region) exhibit broad structural variation, including somatic mosaicism for morphotypes of the salivary gland chromosome set, decondensation of telomeric sites, and the presence of small structural changes, as opposed to populations of Saratov region. As compared with Saratov and Bryansk regions, the Balbiani ring in the B-arm of chromosome I is repressed in populations of Gomel region. It is concluded that the chromosome set of Ch. plumosus in a range of waterbodies of Bryansk and Gomel regions is unstable.

  19. Greening reclamation of arid region

    Energy Technology Data Exchange (ETDEWEB)

    Kamichika, Makio (Tottori Univ. (Japan))


    Arid regions occupy a third of the whole land in the world, and desertification in the rimland makes a problem become more acute. It is also a problem that the large part of such areas is distributed in developing countries. Desertification is defined as a phenomenon, by which the ecological system is degenerated by the change of weather conditions and the pressure of human beings and livestock, and productivity of land is markedly deteriorated. In order to prevent desertification and to promote greening reclamation and agricultural development, it is necessary to analyze desertification mechanism in detail. Artificial factors are overpopulation, too much pasturage, and conversion of grassland into farmland. Natural environmental factors are weather conditions, water resources, soil conditions, etc. It is also important for greening reclamation and development of farm land to evaluate the amount of meteorological resources (such as water resources, energy resources, etc.) and to search for the possibility of their utilization. Because of major condition to grow plants is water environment, investigation and development of water resources are important. If a project ignores the cycle of the ecological system, it might be in danger of retrogradation toward desertification. 8 refs., 10 figs., 4 tabs.

  20. NSF-CBMS Regional Conference

    CERN Document Server

    Rubenfeld, Lester


    The articles of these proceedings arise from a NSF-CBMS regional conference on the mathematical modeling of the hearing process, that was held at Rensselaer Polytechnic Institute in the summer of 1980. To put the a=ticles in perspective, it is best to briefly review the history of suc~ modeling. It has proceeded, more or less, in three stages. The first was initiated by Herman Helmholtz in the 1880's, whose theories dominated the subject for years. However, because of his lack of accurate experimental data and his heuristic arguments it became apparent that his models needed revision. Accordingly, based on the experimental observations of von Bekesy, the "long wave" theories were developed in the 1950's by investigators such as Zwislocki, Peterson, and Bogert. However, as the ex?eri~ents became more refined (such as Rhode's ~wssbauer Measurements) even these models came into question. This has brought on a flurry of 'activity in recent years into how to extend the models to account for these more recent eXT. ...

  7. Cooperative monitoring of regional security agreements

    Energy Technology Data Exchange (ETDEWEB)

    Pregenzer, A.L.; Vannoni, M.; Biringer, K.L.


    This paper argues that cooperative monitoring plays a critical role in the implementation of regional security agreements and confidence building measures. A framework for developing cooperative monitoring options is proposed and several possibilities for relating bilateral and regional monitoring systems to international monitoring systems are discussed. Three bilateral or regional agreements are analyzed briefly to illustrate different possibilities: (1) the demilitarization of the Sinai region between Israel and Egypt in the 1970s; (2) the 1991 quadripartite agreement for monitoring nuclear facilities among Brazil, Argentina, The Argentine-Brazilian Agency for Accounting and Control of Nuclear Materials and the International Atomic Energy Agency; and (3) a bilateral Open Skies agreement between Hungary and Romania in 1991. These examples illustrate that the relationship of regional or bilateral arms control or security agreements to international agreements depends on a number of factors: the overlap of provisions between regional and international agreements; the degree of interest in a regional agreement among the international community; efficiency in implementing the agreement; and numerous political considerations.Given the importance of regional security to the international community, regions should be encouraged to develop their own infrastructure for implementing regional arms control and other security agreements. A regional infrastructure need not preclude participation in an international regime. On the contrary, establishing regional institutions for arms control and nonproliferation could result in more proactive participation of regional parties in developing solutions for regional and international problems, thereby strengthening existing and future international regimes. Possible first steps for strengthening regional infrastructures are identified and potential technical requirements are discussed.

  8. Initiating a regional laboratory network. (United States)

    Nigon, D L


    Wherever we look--on television, in national and local newspapers, or within our own institutions and communities--the biggest issue facing health-care providers is integration. The Clinton plan virtually mandates integrated services, and many individual states are moving ahead rapidly with their own programs. Mandated purchasing alliances will require network services that are focused on cost savings and broad access to the medical system. The incentive to form collaborative medical networks defies our tradition of actively competing for patients and reimbursement dollars. Hospital and physician office laboratories, along with small independent laboratories, face both their greatest challenge and their best opportunity in the changing health-care environment. Those choosing to take up the gauntlet thrown down in the Clinton Administration's commitment to reform will be uniquely positioned to survive and thrive; those who dig their heels firmly into past paradigms will be swept away by the tide of economic change. Whether mandated by law or forged into being by the heat of economic pressure, the formation of integrated care networks positioned to vie for health-care dollars seems inevitable. Some states, including Florida, Washington, and Minnesota, have already passed legislation that anticipates national reform by virtually mandating integrated health-care services. Others are contemplating similar action, and the economic impact is already apparent in a lower-than-projected increase in health-care costs. How can community laboratories position themselves to participate in this rapidly changing environment? Most experts agree that laboratory services must roll themselves into total health-care programs and operate regionally to compete with the national, for-profit conglomerates.(ABSTRACT TRUNCATED AT 250 WORDS)

  9. Cities and regions: problems and potentials


    John B Parr


    The central concern is with the nature of cities and regions and the vagueness that appears to have enveloped each of these terms. Consideration is initially given to the ‘built city’ and how this perspective on the city may be extended in several ways. There follows an examination of the region, with a brief exploration of the classification proposed by Meyer, involving homogeneous, nodal, and policy regions. Attention then turns to two distinctive regional forms (the city-region and the pol...

    Giannoni Margherita


    Full Text Available Abstract Background Among European countries, Italy is one of the countries where regional health disparities contribute substantially to socioeconomic health disparities. In this paper, we report on regional differences in self-reported poor health and explore possible determinants at the individual and regional levels in Italy. Methods We use data from the "Indagine Multiscopo sulle Famiglie", a survey of aspects of everyday life in the Italian population, to estimate multilevel logistic regressions that model poor self-reported health as a function of individual and regional socioeconomic factors. Next we use the causal step approach to test if living conditions, healthcare characteristics, social isolation, and health behaviors at the regional level mediate the relationship between regional socioeconomic factors and self-rated health. Results We find that residents living in regions with more poverty, more unemployment, and more income inequality are more likely to report poor health and that poor living conditions and private share of healthcare expenditures at the regional level mediate socioeconomic disparities in self-rated health among Italian regions. Conclusion The implications are that regional contexts matter and that regional policies in Italy have the potential to reduce health disparities by implementing interventions aimed at improving living conditions and access to quality healthcare.

    Alexey Baranov


    Full Text Available The paper explores various measures of institutional quality in Russian regions, and compares those measures to each other. Such analysis leads to the conclusion that Russian regional institutions are essentially multidimensional, and therefore comparisons of Russian regions in terms of their overall institutional quality could be problematic. New institutional indices are derived from Russian enterprise surveys held under the BEEPS project of the European Bank of Reconstruction and Development. Such indices yield a typology of Russian regions in terms of efficacy of regional administrations’ control over economy and bureaucracy in their regions. Dynamics of regional institutional indices is investigated against the backdrop of Russia-wide institutional trends.JEL classification: D73, D78, H73, H83, O17

  13. Interaction for Innovation: Comparing Norwegian Regions

    Directory of Open Access Journals (Sweden)

    Marina Solesvik


    Full Text Available Building upon insights from earlier investigations of innovation collaboration from a regional perspective as well as the triple helix perspective, local/regional innovation systems and open innovation approaches, this study explores whether cooperation between firms, universities and government increases the intensity of innovation equally for the capital city and peripheral regions. We investigate whether firms located in the capital region benefit more from public support, cooperation with universities, and cooperation with different stakeholders than firms located in peripheral regions. Using logistic binary regressions, we find that capital region firms are generally not more innovative than those located elsewhere. We also find no effect on innovation from cooperation with universities, although public support is related to engagement in product and process innovations. Our results warn against simple applications of triple helix and open innovation approaches, as many forms of collaboration seem to have little impact on innovation, regardless of regional context.

  14. Modeling urban and regional aerosols (United States)

    Sun, Qing

    Aerosol particles in Earth's atmosphere have long been associated with adverse human health effects. They also play an important role in visibility reduction and global climate change. Atmospheric formation and removal of particles are governed by a number of complex dynamic processes which make the aerosol modeling a far more challenging task than the modeling of gas-phase species. Wexler et al. (1994) identified and analyzed the atmospheric aerosol processes that govern particulate mass concentrations and estimated the relative importance of each term using typical atmospheric conditions. In this thesis I start from the general dynamic equation resulted from their analysis and develop a working and optimized aerosol model that can be incorporated into a host Eulerian air quality model to simulate particulate pollution on an urban or a regional scale. Chapter 1 presents the background of the model and highlights the important issues that need to be addressed. Chapter 2 presents the mathematical representation of the aerosol model and introduces an acid equilibrium assumption, that is, when the aerosol particles are close to acid neutral the aerosol hydrogen ion concentration can be assumed to be in equilibrium with the gas-phase acidity. This assumption greatly reduced the CPU requirement of the aerosol model and hence enable us to complete the simulation of an particulate pollution episode in a reasonable time. In Chapter 3 the aerosol model IS incorporated into the Urban Airshed Model to predict the size and composition distribution of particulate matter (PM) during the June 24-25 1987 SCAQS episode. The predicted size distribution is compared to available SCAQS measurement data. In Chapter 4 the aerosol model is further optimized and incorporated into MCNC's Multiscale Air Quality Simulation Platform (MAQSIP) to investigate the particulate pollution in eastern United States using a July 9-13 1995 episode. A cloud model is modified for the sectional

  16. Water resources management in Rostov region (Russia) (United States)

    Nazarenko, O.


    Proper management of water resources leads to the development of the region. Nowadays there is an urgent problem - water shortage. Many European countries face this problem, Russia is not the excluding. In addition, there is a problem not only of water quantity, but quality as well. Although Rostov region is well provided with fresh water, the water resources are unevenly disturbed within region. Rostov region is heavily populated and receive moderate rainfall. Groundwater has a limited capacity for renewal. At the same time, Rostov region is industrial and agricultural one that is why pressures from agriculture, industry and domestic users affect the quantity of water resources. Both water quality and availability must be integrated in long-term planning and policy implications concerning water management. In Russia there are high standards for water quality. Effectively managed water-supply and resource protection systems generate the indispensable basis for agricultural and industrial production. Throughout the Region, urban and rural development has thrived where water sources have been effectively managed. Rostov region can be divided into three parts: northern districts, central part of the region and southern ones. Main cities in the region have not enough available drinking water. In the region ground water is used for curing and water supplying purpose.

    Full Text Available Aim of this work is to evaluate factors responsible for these developments and to show chances for other regions by adopting thismarketing strategy. Besides marketing, interaction of tourism, industry and state was important. Many reasons can be found that shouldresult in a worse development of the region around the Lake of Constance . But instead, today this region has a higher populationgrowth than the average of Baden-Württemberg and is the best economic region outside of urban centers. Scientists spoke aboutan overheated economic growth during the last years that in 2008 comes to a normal but still high level. To attract high potentialworkers and engineers to support further growth, the region has one main advantage to many other regions – its environment. In caseof “Lake of Constance” region, different marketing strategies were used. The complexity of successful marketing for a region is highand finding the right combination of marketing strategies is difficult but can positively influence the development of a region, itseconomy and tourism. At the same time, the marketing for economy and tourism positively reflects degree of popularity in the region.

  1. Difficulty in Distinguishing Posterior Reversible Encephalopathy Syndrome, Hypoxic-Ischemic Insult, and Acute Toxic Leukoencephalopathy in Children. (United States)

    Luckman, Judith; Zahavi, Alon; Efrati, Shai; Gilad, Gil; Snir, Moshe; Michowiz, Shalom; Goldenberg-Cohen, Nitza


    This study aims to describe our experience of unique pediatric neurological cases and associated difficulty in differentiating posterior reversible encephalopathy syndrome (PRES) from hypoxic-ischemic insult (HII), and acute toxic leukoencephalopathy (ATL). The study included three children with a clinical picture suggestive of PRES, HII, and ATL of different etiologies who were diagnosed and treated at a tertiary pediatric medical center in 2011 to 2014. All patients presented with blindness following seizures with asphyxia/aspiration in a syndromatic child, too-rapid lipid infusion in a child with acute lymphoblastic leukemia, and repeated vomiting in a child with cerebral palsy, hydrocephalus, and malfunction of ventriculoperitoneal shunt. All patients had cortical blindness and high-signal foci in the cortical and subcortical regions on magnetic resonance imaging. All children improved. Familiarity with the clinical and radiological characteristics of neurological conditions leading to reversible cortical blindness is essential for diagnosis and management. Distinguishing PRES from HII and ATL can be challenging. Our cases most likely combined these etiologies, with the first patient diagnosed with PRES with HII, the second with PRES with ATL, and the third with focal HII. Given the diversity of the findings and the unclear prognostic significance, studies of the pathophysiology of PRES are warranted. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available The European Union aims to be a financial and economic convergent area, yet there still are notable disparities among regions. The goal of this study is to highlight the degree of synchronization of 275 NUTS 2 regions in European countries, between 2002 and 2011, with an emphasis on the impact of the late 2000's economic crisis.In order to focus on the living standard, the chosen variables were the disposable income of the household, the employment rates of adults (20-64 years old and the regional GDP per inhabitant, which were inserted in a panel data model. Results proved that the regional synchronization is highly influenced by geographical proximity. A notable anomaly concerns capital regions, where, although the regional GDP is higher, disposable income per inhabitant is lower due to higher living costs, not sufficiently compensated by income.

    Full Text Available This paper explains the concept of regional competitiveness and the factors that influence on it. A large number of various authors explain this concept, based on its different aspects, including: productivity, mikroaspekts (firm, quality of human capital, innovation, technology, infrastructure, social capital, etc.. Taking into account complex nature of regional competitiveness, it is difficult to determine a standard definition of this term. The second part of this paper refers to the case of western China. Substantial disparity in regional development is a reality in every geographically large country, and the causes of the disparity are numerous and complex. Regional inequality has been an important issue in China. This paper generally summarized China's Western regions geography, government policies and development situation. The authors put forward some practical strategies on how to help the western regions create a favorable environment to attract national and international investment.

  6. Expanded uncertainty regions for complex quantities (United States)

    Hall, B. D.


    The expanded measurement uncertainty of a complex quantity is a region in the complex plane surrounding the measured value. This paper considers different shaped uncertainty regions in the form of ellipses, circles, rectangles and parallelograms. The different types of region are compared, under a variety of measurement error conditions, with regard to coverage probability and relative area. Elliptical confidence regions are commonly used in multivariate statistics. However, this shape has not been adopted widely in metrology, perhaps because there is no simple way to report the extent of an elliptical region. The other shapes considered are easier to use. Unfortunately, the coverage probability of circular uncertainty regions is found to be sensitive to both the form of the distribution of measurement errors and to the number of degrees of freedom, making this shape a poor choice. Parallelograms and rectangles both performed well, with parallelograms giving the best results overall.

    Regional powers are not always benevolent leaders when it comes to the building of regional institutions. While powerful states - particularly the "new" rising powers - may have a vested interest in regionalism as a means of projecting influence, regional powers may behave as coercive or benevolent leaders, or alternatively display an absence of leadership altogether. The drivers of varying regional power behavior can be attributed to their competing concerns regarding (economic) power, funct...

  19. Formation of paradigmatic theory of regional economy

    Directory of Open Access Journals (Sweden)

    Aleksandr Ivanovich Tatarkin


    Full Text Available This paper reviews the evolution of scientific ideas about the regional economy as an independent direction of economic knowledge. The growing interest of scientists, university lecturers and specialists to the regional economy is noticed. The authors pay special attention to the origins of the regional economy, the contribution of Russian scientists to the disclosure of the content and nature of economic regionalization of the country as well as highlight the role of Soviet geographers and economists in developing the theory of clusters and the study of challenges to the rational distribution of production forces. It is emphasized that the new scientific discipline — regional economy — was born in the acute scientific discussions between Soviet geographers and economists, particularly regarding the subject of investigation. The conclusion is substantiated that so far in economic science four major views on the subject of understanding and interpretation of the regional economy were formed. The authors pay attention to the fact that at present there is a further extension of the subject of the regional economy, mainly over the border of the material space and location of productive forces. The paper concludes that the formation of a modern paradigm of regional economy should be based on several basic principles, among which are the following ones: consideration of the regional economy as an evolving complex structural discipline; territoriality as a dominant feature of any research in the regional economy; the imperative of any study that claims to belong to a regional economy is not only to establish general patterns of development and organization of economic life in the territory, but also the identification of its regional (local specific

The paper aims to provide an overview of the regional players’ activity in the framework of the BSEC which are involved in sustaining and strengthening of this organization and also in continuing the reform process in it, developing in the same time relations of cooperation with the EU and other regional initiatives. Methods. This article embraces a row of different scientific methods of data analysis, predictive analytics, historical and statistical overview, descriptive method, case study etc. Results. The countries from the Black Sea basin are the most vulnerable to potential risks and shocks due to the instability of the region. This requires the interstate cooperation in the Black Sea area with no tradition in this field several decades ago. In the same time, countries like Turkey, Romania or Russia aspire to play the role of the regional leader, which can cause regional rivalries. With the help of the regional cooperation and the BSEC in particular, regional countries could learn how to work together for the common benefit. The creation of stable markets, interconnected and transparent regional organizations and initiatives would largely contribute to the security and stability of the Black Sea region.

  8. Lipectomy of the ilio-lumbosacral region. (United States)

    Chamosa, Miguel


    In the past, several techniques for raising the gluteal mass have been described, all of which were based on dermolipectomies of major or minor extension. The main disadvantage of these dermolipectomies is the visible external scar. The author presents his technique for lipectomy of the ilio-lumbosacral region. It is proposed that multiplanar liposuction in this region lengthens the lumbar lordotic curve and results in upward traction on the buttocks, resulting in a more youthful contour of the region. The article describes a series of 98 patients with lipodystrophy of the ilio-lumbosacral area who underwent liposuction of the region and were highly satisfied with the results.

  9. Regional quality of living in Europe

    Directory of Open Access Journals (Sweden)

    Piet Lagas


    Full Text Available This article sets out the conceptual framework and results of Regional Quality of Living indicators that were developed in order to benchmark European NUTS2 regions. Nine non-business-related indicators are constructed to support the goal of policy makers to improve the attractiveness of regions and cities for people or companies to settle in, and by doing so create economic growth. Each of the constructed indicators represents a pillar of the Quality of Living. The highest indicator scores are found for regions within Switzerland, Sweden, Norway and the Netherlands. Some countries show a wide divergence between regional scores. The southern regions of Italy and Spain, for example, have significantly lower scores than those in the north. In addition, capital city regions have better RQI scores. A positive correlation was found between the average RQI scores and both GDP per capita and weighted population density. Compared to GDP per capita, weighted population density has a modest influence on the RQI score. The European regions are divided into 11 clusters, based upon GDP per capita and weighted population density in order to benchmark a region with its peers.

  11. Threats to economic security of the region

    Directory of Open Access Journals (Sweden)

    Y. A. Salikov


    Full Text Available Various aspects of economic security are in sight of the researchers for more than two decades. Today in the economic literature widely presents the conceptual aspects of economic safety of the state. Theoretical and methodological foundations of the study of this multifaceted problem lies in the researches of many domestic and foreign scientists, which are the basic levels of economic security. Among the priority levels include, in our view, the regional level (meso-level and actual problems of economic security studied to date lack detail. Economic development regions of the country has its own specifics, which is projected to the achieving of regional and national economic security. The article summarizes the approaches to definition of essence of the category “economic security of the region” and was given its author’s interpretation, considers the reasons of appearance and development of crisis situations causing threats to the economic security of the region. Given that the prevention of threats and reduction of their consequences is the basis of regional economic security, the article identifies the main threats to economic security, as well as the peculiarities of their manifestations (for example, the most significant threats to economic security of the Voronezh region, as well as the proposed activities in support of regional economic security and stated objectives of regional economic policy, the solution of which is aimed at ensuring the economic security of the region. In addition, it is proved that the actual problems of economic security must be constantly in sight of the regional leadership and find its solution in government documents and policy programmes promising socio-economic development of the region.

  12. The Twist Limit for Bipolar Active Regions (United States)

    Moore, Ron; Falconer, David; Gary, Allen


    We present new evidence that further supports the standard idea that active regions are emerged magnetic-flux-rope omega loops. When the axial magnetic twist of a cylindrical flux rope exceeds a critical amount, the flux rope becomes unstable to kinking, and the excess axial twist is converted into writhe twist by the kinking. This suggests that, if active regions are emerged omega loops, then (1) no active region should have magnetic twist much above the limit set by kinking, (2) active regions having twist near the limit should often arise from kinked omega loops, and (3) since active regions having large delta sunspots are outstandingly twisted, these arise from kinked omega loops and should have twist near the limit for kinking. From each of 36 vector magnetograms of bipolar active regions, we have measured (1) the total flux of the vertical field above 100 G, (2) the area covered by this flux, and (3) the net electric current that arches over the polarity inversion line. These three quantities yield an estimate of the axial magnetic twist in a simple model cylindrical flux rope that corresponds to the top of the active region s hypothetical omega loop prior to emergence. In all 36 cases, the estimated twist is below the critical limit for kinking. The 11 most twisted active regions (1) have estimated twist within a factor of approx.3 of the limit, and (2) include all of our 6 active regions having large delta sunspots. Thus, our observed twist limit for bipolar active regions is in good accord with active regions being emerged omega loops.

  13. Coactivation of the Default Mode Network regions and Working Memory Network regions during task preparation. (United States)

    Koshino, Hideya; Minamoto, Takehiro; Yaoi, Ken; Osaka, Mariko; Osaka, Naoyuki


    The Default Mode Network (DMN) regions exhibit deactivation during a wide variety of resource demanding tasks. However, recent brain imaging studies reported that they also show activation during various cognitive activities. In addition, studies have found a negative correlation between the DMN and the working memory network (WMN). Here, we investigated activity in the DMN and WMN regions during preparation and execution phases of a verbal working memory task. Results showed that the core DMN regions, including the medial prefrontal cortex and posterior cingulate cortex, and WMN regions were activated during preparation. During execution, however, the WMN regions were activated but the DMN regions were deactivated. The results suggest that activation of these network regions is affected by allocation of attentional resources to the task relevant regions due to task demands. This study extends our previous results by showing that the core DMN regions exhibit activation during task preparation and deactivation during task execution.

    Full Text Available Economic disparities are disparities between levels of economicdevelopment of the areas or regions within a national economy. If economic literature hasfailed to explain the causes of inequalities in economic development of different regions of theEU, this issue became a priority in EU economic policy, especially after the adhesion ofGreece, Spain and Portugal, countries characterized by a lower level of development fromother EU countries and also marked by significant regional imbalances. European Unionsupports reducing disparities between different regions of Member States so that all regionsand their people to benefit from economic and social advantages of the Union. This paper aimsto highlight disparities between the macro-regions in Romania. Regional demarcation criterionin the NUTS system is the population’s number within a territory. Most pertinent argument isthat the goal of all activities in a society lies in meeting the needs of the individual and of thecommunity. This possibility is ensured by a certain level of economic development in the region.Less developed areas of Romania are located in Northern Moldova and in the South EasternRomanian Plain and the more developed areas include, in addition to Bucharest andConstanta, Transylvania and Banat regions.

    Full Text Available The author considered problems and contradictions of modern innovation policy in Russia. It is shown, that at present time regions are removed from management of science-technical complex and spatial priorities are not produced. It is a serious factor of risk for conservation perspectives of innovation development for Russia. With taking into account of world experience main districts of rise effects regional police were formulated. It is underlined, that creation conditions for transformation of regional authorities in active subjects of innovation policy is necessary condition for building vital innovation system. It is shown, that state innovation policy must be constructed at combination of next principles: a support science-technical potential of regions — generators of innovation and creation conditions for its realization; b using of innovations for evening-out disproportions of social-economic development between regions; c widening powers and financial possibilities of regions at management of innovation climate. Methodical approaches for making effective mechanisms of management of innovation processes of territory are opened. Typology of Russian regions with high and middle degree of innovation climate is proposed, which takes level of science and innovation potential of territory and also degree of comfort of social-economic conditions for development of innovation activity are offered. Peculiarities of innovation strategy for different types of regions are defined. This typology may be used for substantiation spatial priorities of innovation strategy of Russia.

    The extraordinary delay of the daily variation of absorption and electron density observed in the ionospheric D region above the Persian Gulf in 1976 observed from the research vessel 'Akademik Kurchatov' may be a consequence of air pollution by oil production by-products. It is suggested that the Gulf war might also have caused a lower ozone abundance in that region.

  12. Regions, Regionalisme, Regionalisation. Clarifications conceptuelles et terminologiques

    Directory of Open Access Journals (Sweden)

    Dinu Balan


    Full Text Available This study points out the proteiphorme dimension of the three terms-concepts used in the actually political and juridical-administrative vocabulary, in relation with the transformations produced both in the European and national areas, in connection with the phenomenology of regionalization and its adjoining process. Our analysis is focused upon the terminological aspects and underlines both the signification and the practical implications of these concepts, in an interdisciplinary interpretation frame. We underline the importance of these terms in the European construction process. If they are difficult to prove an obvious relation between the regional politics of the European Union and the development of a regional tendency in Europe, they can say that the two phenomena cross and interfere themselves. The European integration and the regional tendency are not contradictory phenomena, but they join in the ample process concerning the new statute of the national state in a broader Europe. The regionalization and the regionalism don't only limit themselves at the regional politics of the bureaucracy from Brussels, so the process connected with the development of the regions involve very many factories.

  19. Failure probability of regional flood defences

    Directory of Open Access Journals (Sweden)

    Lendering Kasper


    Full Text Available Polders in the Netherlands are protected from flooding by primary and regional flood defence systems. During the last decade, scientific research in flood risk focused on the development of a probabilistic approach to quantify the probability of flooding of the primary flood defence system. This paper proposed a methodology to quantify the probability of flooding of regional flood defence systems, which required several additions to the methodology used for the primary flood defence system. These additions focused on a method to account for regulation of regional water levels, the possibility of (reduced intrusion resistance due to maintenance dredging in regional water, the probability of traffic loads and the influence of dependence between regional water levels and the phreatic surface of a regional flood defence. In addition, reliability updating is used to demonstrate the potential for updating the probability of failure of regional flood defences with performance observations. The results demonstrated that the proposed methodology can be used to determine the probability of flooding of a regional flood defence system. In doing so, the methodology contributes to improving flood risk management in these systems.
