    Mantle cell lymphoma (MCL) is a distinct subtype of malignant lymphoma which is characterized by the chromosomal translocation t(11;14)(q13;q32) resulting in constitutional overexpression of cyclin D1 and cell cycle dysregulation in almost all cases. Clinically, MCL shows an aggressive clinical course with a continuous relapse pattern and a median survival of only 3-5 years. However, recently a subset of 15% long-term survivors has been identified with a rather indolent clinical course. Targeted strategies include the proteasome inhibitors, immune modulatory drugs (IMiDs), mammalian target of rapamycin (mTOR) inhibitors and especially inhibitors of the B-cell receptor pathway. Our recent annual conference focused on the molecular pathogenesis of the disease and how these underlying molecular alterations may guide the selection and integration of innovative approaches for therapy. This review of the meeting covers in particular the identification of indolent cases, and deals with the role of the B-cell receptor pathway in MCL, as well as the detection of minimal residual disease and implementation of molecular approaches in current clinical trials.

    The UK Renal Association (RA) and National Institute for Health and Clinical Excellence (NICE) have published Clinical Practice Guidelines which include recommendations for management of anaemia in established renal failure. To determine the extent to which the guidelines for anaemia management are met in the UK. Quarterly data (haemoglobin (Hb) and factors that influence Hb) extracts from renal centres in England, Wales, Northern Ireland (EWNI), and annual data from the Scottish Renal Registry for incident and prevalent renal replacement therapy (RRT) cohorts for 2008 were analysed by the UK Renal Registry (UKRR). In the UK, in 2008 57% of patients commenced dialysis therapy with Hb >or= 10.0 g/dl (median Hb 10.2 g/dl). For incident patients the Hb at 3 and 6 months of dialysis treatment was 11.4 and 11.7 g/dl respectively. The median Hb of haemodialysis (HD) patients was 11.6 g/dl with an interquartile range (IQR) of 10.6-12.5 g/dl. Of HD patients 85% had a Hb >or= 10.0 g/dl. The median Hb of peritoneal dialysis (PD) patients in the UK was 11.7 g/dl (IQR 10.8-12.6 g/dl). Of UK PD patients 89% had a Hb >or= 10.0 g/dl. The median ferritin in HD patients in EWNI was 436 mg/L (IQR 289-622) and 95% of HD patients had a ferritin >or= 100 mg/L. The median ferritin in PD patients was 246 mg/L (IQR 141-399) with 84% of PD patients having a ferritin >or= 100 mg/L. In EWNI the mean ESA dose was higher for HD than PD patients (9,166 vs. 6,302 IU/week). Last year for the first time a small fall (from 85.9% in 2006 to 85.6% in 2007) in the % of HD patients with a Hb of >or= 10 g/dl which was thought to be related to the implementation of the new Hb Standard which has a target range of 10.5-12.5 g/dl was seen. This year attainment of Hb >or= 10 g/dl in HD patients fell again slightly to 85.3%. In HD patients, 54% of patients had a Hb >or= 10.5 and

    The value of nonfuel minerals produced in North Carolina decreased 6.2% from that of 1990. The value dropped from $589.7 million in 1990 to $552.9 million in 1991, largely as a result of the recession that has impacted the Nation in recent years. Decreases in the sales of the State's leading mineral commodity, crushed stone, as well as clays, feldspar, gemstones, scrap mica, olivine, construction sand and gravel, and pyrophyllite, more than offset small to moderate increases in the sales of lithium minerals, peat, phosphate rock, and industrial sand and gravel.

    2015-08-20

    NASA Spitzer Space Telescope celebrated its 12th anniversary with a new digital calendar showcasing some of the mission most notable discoveries and popular cosmic eye candy. The digital calendar is online at http://www.jpl.nasa.gov/images/spitzer/20150820/Spitzer12thAnniversaryCalendar.pdf The calendar follows the life of the mission, with each month highlighting top infrared images and discoveries from successive years -- everything from a dying star resembling the eye of a monster to a star-studded, swirling galaxy. The final month includes a brand new image of the glittery star-making factory known as the Monkey Head nebula. Spitzer, which launched into space on August 25, 2003, from Cape Canaveral, Florida, is still going strong. It continues to use its ultra-sensitive infrared vision to probe asteroids, comets, exoplanets (planets outside our solar system) and some of the farthest known galaxies. Recently, Spitzer helped discover the closest known rocky exoplanet to us, named HD219134b, at 21 light-years away. In fact, Spitzer's exoplanet studies continue to surprise the astronomy community. The telescope wasn't originally designed to study exoplanets, but as luck -- and some creative engineering -- would have it, Spitzer has turned out to be a critical tool in the field, probing the climates and compositions of these exotic worlds. This pioneering work began in 2005, when Spitzer became the first telescope to detect light from an exoplanet. http://photojournal.jpl.nasa.gov/catalog/PIA19872

    The 12th generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2014 by the Working Group V-MOD appointed by the International Association of Geomagnetism and Aeronomy (IAGA). It updates the previous IGRF generation with a definitive main field model for epoch 2010.0, a main field model for epoch 2015.0, and a linear annual predictive secular variation model for 2015.0-2020.0. Here, we present the equations defining the IGRF model, provide the spherical harmonic coefficients, and provide maps of the magnetic declination, inclination, and total intensity for epoch 2015.0 and their predicted rates of change for 2015.0-2020.0. We also update the magnetic pole positions and discuss briefly the latest changes and possible future trends of the Earth's magnetic field.

    A newly developed setup for continuous flow analysis (CFA) of ice cores in Copenhagen is optimized for high resolution analysis of four components: Soluble sodium (mainly deriving from sea salt), soluble ammonium (related to biological processes and biomass burning events), insoluble dust particles (basically transported from Asian deserts to Greenland), and the electrolytic melt water conductivity (which is a bulk signal for all ionic constituents). Furthermore, we are for the first time implementing a flow cytometer to obtain high quality dust concentration and size distribution profiles based on individual dust particle measurements. Preliminary measurements show that the setup is able to resolve annual layers of 1 cm thickness. Ice flow models predict that annual layers in the Eemian section of the Greenland NorthGRIP ice core (130-115 ka BP) have a thickness of around 1 cm. However, the visual stratigraphy of the ice core indicates that the annual layering in the Eemian section may be disturbed by micro folds and rapid crystal growth. In this case study we will measure the impurity content of an Eemian segment of the NorthGRIP ice core with the new CFA setup. This will allow for a comparison to well-known impurity levels of the Holocene in both Greenland and Antarctic ice and we will attempt to determine if annual layers are still present in the ice.

    The Anglo-French Physical Acoustics Conference (AFPAC) had its 12th annual meeting in Villa Clythia, Fréjus, France, from 16th to 18th January 2013. This series of meetings is a collaboration between the Physical Acoustics Group (PAG) of the Institute of Physics and the Groupe d'Acoustique Physique, Sous-marine et UltraSonore (GAPSUS) of the Société Française d'Acoustique. This year, attendees got the opportunity to see the French Riviera with its Mediterranean vegetation covered by a nice thick snow layer. The participants heard 34 excellent oral presentations and saw 3 posters covering an exciting and diverse range of subjects and of frequencies, from ultrasonic wave propagation in chocolate to metamaterials applied to seismic waves for protecting buildings. Among them, invited talks were given by Pr F A Duck ( Enhanced healing by ultrasound: clinical effects and mechanisms), Pr. J-C Valiére, who actually gave two invited talks ( 1. Measurement of audible acoustic particle velocity using laser: Principles, signal processing and applications, 2. Acoustic pots in ancient and medieval buildings: Literary analysis of ancient texts and comparison with recent observations in French churches), Dr P Huthwaite ( Ultrasonic imaging through the resolution of inverse problems), Dr X Lurton ( Underwater acoustic systems on oceanographic research vessels: principles and applications), Dr S Guenneau ( From platonics to seismic metamaterials). For the fifth consecutive year AFPAC is followed by the publication of its proceedings with 12 peer-reviewed papers which cover the most recent research developments in the field of Physical Acoustics in the UK and France.

    Owing to the lack of absolutely dated oceanographic information before the modern instrumental period, there is currently significant debate as to the role played by North Atlantic Ocean dynamics in previous climate transitions (for example, Medieval Climate Anomaly-Little Ice Age, MCA-LIA). Here we present analyses of a millennial-length, annually resolved and absolutely dated marine δ(18)O archive. We interpret our record of oxygen isotope ratios from the shells of the long-lived marine bivalve Arctica islandica (δ(18)O-shell), from the North Icelandic shelf, in relation to seawater density variability and demonstrate that solar and volcanic forcing coupled with ocean circulation dynamics are key drivers of climate variability over the last millennium. During the pre-industrial period (AD 1000-1800) variability in the sub-polar North Atlantic leads changes in Northern Hemisphere surface air temperatures at multi-decadal timescales, indicating that North Atlantic Ocean dynamics played an active role in modulating the response of the atmosphere to solar and volcanic forcing.

    Lolk, Nina K.

    1992-01-01

    The climatological annual cycle of the Pacific North Equatorial Countercurrent (NECC) simulated by an ocean general circulation model (OGCM) was studied. The longitudinal variation of transports, degree of geostrophy, and the relationship between Ekman pumping and vertical displacement of the thermocline were emphasized. The longitudinal variation was explored using six sections along 150 deg E, 180 deg, 160 deg W, 140 deg W, 125 deg W, and 110 deg W. A primitive equation OGCM of the Pacific Ocean was run for three years and the fields used were from the third year. The fields consisted of zonal, meridional, and vertical current components and temperature and salinity averaged every three days. The model was forced with the Hellerman and Rosenstein climatological wind stress. The mean annual eastward transport (19.9 Sv) was largest at 160 deg W. The maximum-current boundaries along 160 deg W were 9.2 deg N (1.0 deg), 5.1 deg N (1.1 deg), and 187 m (90.6 m). The annual-cycle amplitude of the NECC was greatest between 160 deg W and 140 deg W. Although the NECC is geostrophic to the first order, deviations from geostrophy were found in the boreal spring and summer near the southern boundary and near the surface. Meridional local acceleration played a role between 3 deg N-5 deg N.

    This web site contains the Federal Geographic Data Committee-compliant metadata (documentation) for digital data produced for the North Carolina, Department of Environment and Natural Resources, Public Water Supply Section, Source Water Assessment Program. The metadata are for 11 individual Geographic Information System data sets. An overlay and indexing method was used with the data to derive a rating for unsaturated zone and watershed characteristics for use by the State of North Carolina in assessing more than 11,000 public water-supply wells and approximately 245 public surface-water intakes for susceptibility to contamination. For ground-water supplies, the digital data sets used in the assessment included unsaturated zone rating, vertical series hydraulic conductance, land-surface slope, and land cover. For assessment of public surface-water intakes, the data sets included watershed characteristics rating, average annual precipitation, land-surface slope, land cover, and ground-water contribution. Documentation for the land-use data set applies to both the unsaturated zone and watershed characteristics ratings. Documentation for the estimated depth-to-water map used in the calculation of the vertical series hydraulic conductance also is included.

  12. The annual silica cycle of the North Pacific subtropical gyre

    Silica cycling in the upper 175 m of the North Pacific Subtropical Gyre was examined over a two year period (January 2008-December 2009) at the Hawaii Ocean Time-series (HOT) station ALOHA. Silicic acid concentrations in surface waters ranged from 0.6 to 1.6 μM, exhibiting no clear seasonal trends. Biogenic silica concentrations and silica production rates increased by an order of magnitude each summer following stratification of the upper 50 m reaching values of 157 nmol Si L -1 and 81 nmol Si L -1 d -1, in 2008 and 2009, respectively. Sea surface height anomalies together with analyses of variability in isothermal surfaces at 150-175 m indicated that the summer periods of elevated biogenic silica were associated with anticyclonic mesoscale features during both years. Lithogenic silica concentrations increased in the spring during the known period of maximum atmospheric dust concentrations with maximum values of 36 nmol Si L -1 in the upper 10 m. Dust deposition would enhance levels of dissolved iron in surface waters, but there was no response of diatom biomass or silica production to increases in near-surface ocean lithogenic silica concentrations suggesting iron sufficiency of diatom silica production rates. Low ambient silicic acid concentrations restricted silica production rates to an average of 43% of maximum potential rates. Si sufficiency only occurred during the summer period when diatom biomass was elevated suggesting that bloom diatoms are adapted to exploit low silicic acid concentrations. Annual silica production at HOT is estimated to be 63 mmol Si m -2 a -1 with summer blooms contributing 29% of the annual total. Diatoms are estimated to account for 3-7% of total phytoplankton primary productivity, but 9-20% of organic carbon export confirming past suggestions that diatoms are relatively minor contributors to primary productivity and autotrophic biomass, but important contributors to new and export production in oligotrophic open-ocean ecosystems

    the region bridging the present-day Syro-Turkish border. The long and devastating series of shakes in 1156-59 and the great earthquake of June 1170, affected a huge area within the current territories of north-western Syria, northern Lebanon and the region of inter Antioch (modern Antakya, in southern Turkey). The effects of the earthquakes in August 1110 and June 1117 have been attested to in southern Lebanon and Palestine. On the grounds of the detailed seismic scenarios of the 5 most documented earthquakes we have also been able to advance some hypotheses as to the seismogenic structures involved. In the first half of the 12th century the most intense seismicity seems to be concentrated in the zones bordering south-eastern Turkey and north-western Syria, suggesting a likely involvement both of the northernmost portion of the Dead Sea Fault System (DSFS), and the south-western segment of the East-Anatolian Fault System (EAFS), as well as, perhaps, also the convergence structures present in south-eastern Turkey (Bitlis suture zone?). Beginning from around mid-1150 the greatest seismic activity seems to migrate more southwards, along the structures of the DSFS that cross western Syria (Ghab and Missyaf faults) and northern Lebanon (Akkar fault?). Lastly, for the great event of 1170, the sources we have retrieved and analysed contain information concerning damage or felt effects in slightly fewer than 30 Crusader and Arab locations, 15 of which new and never before identified. The detailed macroseismic picture that has been reconstructed has thus also allowed us to propose an estimate of the main shock parameters for this earthquake.

    Buckman, Stephen; Sullivan, James; White, Ronald

    2011-01-01

    Preface These proceedings arose from the 12th International Workshop on Slow Positron Beam Techniques (SLOPOS12), which was held on Magnetic Island, North Queensland, Australia, between 1-6th August 2010. Meetings in the SLOPOS series are held (roughly) every three years and have now been held on (almost) all continents, indicating the truly international nature of the field. SLOPOS12 marked the second time that the Workshop had been held in the southern hemisphere, and the first time in Australia. SLOPOS12 attracted 122 delegates from 16 countries. Most encouraging was the attendance of 28 student delegates, and that about half of the overall delegates were early career researchers - a good sign for the future of our field. We also enjoyed the company of more than a dozen partners and families of delegates. In a slight departure from previous SLOPOS meetings, the International Advisory Committee approved a broader scope of scientific topics for inclusion in the program for the 2010 Workshop. This broader scope was intended to capture the applications of positrons in atomic, molecular and biomedical areas and was encapsulated in the byeline for SLOPOS-12: The 12th International Workshop on Slow Positron Beam Techniques for Solids, Surfaces, Atoms and Molecules. The scientific and social program for the meeting ran over 6 days with delegates gathering on Sunday August 1st and departing on August 6th. The scientific program included plenary, invited, contributed and student lectures, the latter being the subject of a student prize. In all there were 53 oral presentations during the week. There were also two poster sessions, with 63 posters exhibited, and a prize was awarded for the best poster by a student delegate. The standard of the student presentations, both oral and posters, was outstanding, so much so that the judging panel recommended an additional number of prizes be awarded. Topics that were the focus of invited presentations and contributed papers at

    1989-01-01

    Introduction: The North American Breeding Bird Survey (BBS) is run by approximately 2,000 skilled amateur ornithologists, and is coordinated cooperatively by the U.S. Fish and Wildlife Service and the Canadian Wildlife Service. Beginning in 1966, BBS cooperators have been collecting standardized information on North American bird populations. The BBS is a roadside survey, comprised of permanent routes that are surveyed yearly. Each route is 39.4 km (24.5 miles) long and consists of 50 stops spaced 0.8 km (0.5 mile) apart. All birds heard or seen during a 3-min observation period at each stop are recorded, and the sum of the individual stops for each species is used as an index of species density on the route. In this report, we present the population changes of the 222 bird species reported on > 50 BBS routes during 1987 and 1988. Population trends for 1966-87 are presented for comparison. Owing to space constraints, trends are not reported for States, Provinces, or physiographic regions. Instead, we present maps illustrating patterns of population change for selected species, and summarize State and physiographic strata patterns of population change as the proportion of species that increased in each region. Detailed State, Provincial, and physiographic strata changes arc available to interested readers.

All birds heard or seen during a 3-min observation period at each stop are recorded, and, for each species, the sum of the counts on individual stops is used as an index of species density on the route. Survey routes occur throughout the continental United States and most of Canada. Here, we present the population changes of the 251 bird species reported on the 50 or more BBS routes in the survey region during 1988 and 1989. Population trends for 1966-89 are presented for comparison. The direction and significance of population changes between the years for the 306 species occurring on 10 or more routes within States and Provinces are summarized in Appendix B. The pattern of population changes for selected species is graphically summarized on maps by physiographic stratum.

    We studied onchocerciasis transmission and impact on ocular morbidity in three health districts in North Region, Cameroon, where annual mass ivermectin treatment has been provided for 12–17 years. The studies, which took place from 2008 to 2010, consisted of skin snips for microfilariae (mf), palpation examinations for nodules, slit lamp examinations for mf in the eye, and Simulium vector dissections for larval infection rates. Adults had mf and nodule rates of 4.8% and 13.5%, respectively, and 5.5% had mf in the anterior chamber of the eye. Strong evidence of ongoing transmission was found in one health district, where despite 17 years of annual treatments, the annual transmission potential was 543 L3/person per year; additionally, children under 10 years of age had a 2.6% mf prevalence. Halting ivermectin treatments in North Cameroon now might risk recrudescence of transmission and ocular disease. PMID:22144441

    Annually laminated stalagmites can be used to construct a precise chronology, and variations in laminae thickness provide an annual growth-rate record that can be used as a proxy for past climate and environmental change. Here, we present and analyse the first composite speleothem annual growth-rate record based on five stalagmites from the same cave system in northwest Scotland, where precipitation is sensitive to North Atlantic climate variability and the winter North Atlantic Oscillation (NAO). Our 3000-year record confirms persistently low growth-rates, reflective of positive NAO states, during the Medieval Climate Anomaly (MCA). Another persistently low growth period occurring at 290-550 CE coincides with the European Migration Period, and a subsequent period of sustained fast growth-rate (negative NAO) from 600-900 AD provides the climate context for the Viking Age in northern and western Europe.

    Pronounced laminated layering is observed in the Visual Stratigraphy (VS) of the NorthGRIP ice core (75.1N; 42.3W) throughout the last glacial period. In the cold Greenland Isotopic Stadial 21 at around 2580 m depth, where the ice has an age of approximately 78 kyr, the layer thickness is estimated to be just below 1 cm. In order to verify that the observed layers are annual, we have carried out measurements of electrolytical conductivity and dust concentration at mm resolution in 2 meters of that ice. Together with the VS profile we apply those data to perform a dating, that results in a mean annual layer thickness of 0.8 cm, which is in good accordance with the modelled NorthGRIP time scale 'ss09sea'. This result makes us confident that the stratigraphic dating of the NorthGRIP ice core can be extended back to at least 80 kyr BP.

  13. The Mars 6 Landing, 12th March 1974

    NASA Astrophysics Data System (ADS)

    Harvey, B.

    The Soviet Union sent five landers to Mars: 2MV3 in 1962; Mars 2 and 3 in 1971 and Mars 6 and 7 in 1973. Influenced by astrobiologist Gavril Tikhov, early Soviet designers believed that it would be possible to reach the surface of Mars using large parachutes. When the atmosphere was found to be much thinner than anticipated, the landers were redesigned to incorporate rockets. The Mars 2 and 3 missions were impeded by a poor level of navigational knowledge, making it difficult to achieve precise entry trajectories for the subsequent touchdowns. Despite that, Mars 3 achieved the first soft landing on Mars in 1971 and a brief surface transmission. Two years later, the Soviet Union achieved the first temperature and pressure profile of the atmosphere of Mars down to the surface when Mars 6 landed in the Mare Erythraeum on 12th March 1974. Because of internal debates within the Soviet space programme and the nature of news management at the time, the achievement of Mars 6 has been obscured.

    The 12th International Conference on Substorms (ICS-12) was held at the Ise-Shima Royal Hotel in Shima, Japan, on November 10-14, 2014. There were 125 attendees including 68 from foreign countries. The ICS has been held every 2 years since 1992 to discuss substorms, which are fundamental global-scale disturbances in the Earth's magnetosphere. The year 2014 marked the 50th anniversary of the first publication about substorms (Akasofu 1964). The conference included three tutorial lecturers (Profs. S.-I. Akasofu, V. Angelopoulous, and D. Baker), as well as many international scientists, to discuss substorm processes in the tail, their Interactions with the inner magnetosphere and the ionosphere, substorm currents and their dynamics and energetics, the role of MagnetoHydroDynamics (MHD) and kinetic instabilities, storm-substorm relationships, ULFELFVLF waves, and non-Earth substorm-like features. Prof. Akasofu also gave an evening talk about the history of auroral research since the nineteenth century with photographs that inspired and intrigued the young scientists and students in attendance.

  15. First Annually Resolved Marine Temperature Series For The Last 1000 Years From The North Atlantic

    There remain very few high-resolution records of marine climate variability covering the last 1000 years; annually-resolved series have hitherto been confined to coral archives from the low latitude oceans and do not cover the full millennium. We have constructed a 1357-year crossdated sclerochronology based on annual growth increments in the long-lived bivalve mollusc Arctica islandica, collected by dredge from the temperate North Atlantic (Grimsey, North Icelandic shelf, 80 m water depth; Butler et al. 2013). We present here annual- to sub-annually-resolved oxygen isotope data from the last 1000 years of this absolute chronology. Radiocarbon analysis of the series demonstrates variability in the marine reservoir effect (ΔR) controlled by Atlantic vs. Arctic water masses (Irminger Current, East Icelandic Current) with enhanced ingress of Irminger Current water during the Medieval Climate Anomaly and since AD 1900; the Little Ice Age is conversely characterized by Arctic water masses (Wanamaker et al. 2012). We use the ΔR variability to correct for the isotopic content of seawater (δ18Ow) and hence convert δ18Oshell to seawater temperature at 80m, a calibration supported by comparison with instrumental series. This reveals the evolution of North Atlantic seawater temperatures over the last 1000 years in unprecedented detail and provides a basis for the comparison of marine with terrestrial series at the same resolution for the first time.

  16. Low-Flow Characteristics and Mean Annual Discharge of North Branch Manitowoc River at Potter, Wisconsin

    The low-flow characteristics presented in this report are the annual minimum 7-day mean flows at the 2-year recurrence interval and 10-year recurrence interval. They were determined just downstream from the confluence of the three streams forming the North Branch Manitowoc River and, based on natural-flow conditions, are 0.0 cubic foot per second (0.0 cubic metre per second). Observations made in October 1974 showed that the natural discharge of the three streams forming the North Branch Manitowoc River was 0.0 cubic foot per second (0.0 cubic metre per second). A discharge of 0.30 cubic foot per second (0.008 cubic metre per second) was measured in the tributary from Hilbert but this was predominantly effluent from the sewage-treatment plant and a cheese factory in Hilbert. The mean annual discharge for the North Branch Manitowoc River at Potter is 27 cubic feet per second (0.76 cubic metre per second). This was based on the estimated and recorded discharge for June 1, 1974, to May 31, 1975, for the North Branch Manitowoc River at Potter site and an adjustment based on the long-term mean annual discharge at gaging station 04086000, Sheboygan River at Sheboygan.

    The 12th International Workshops on Opportunistic Protists (IWOP-12) was held in August 2012 in Tarrytown, New York. The objectives of the IWOP meetings are to: (1) serve as a forum for exchange of new information among active researchers concerning the basic biology, molecular genetics, immunology, biochemistry, pathogenesis, drug development, therapy, and epidemiology of these immunodeficiency-associated pathogenic eukaryotic microorganisms that are seen in patients with AIDS and (2) foster the entry of new and young investigators into these underserved research areas. The IWOP meeting focuses on opportunistic protists, e.g. the free-living amoebae, Pneumocystis, Cryptosporidium, Toxoplasma, the Microsporidia, and kinetoplastid flagellates. This conference represents the major conference that brings together research groups working on these opportunistic pathogens. Slow but steady progress is being achieved on understanding the biology of these pathogenic organisms, their involvement in disease causation in both immune-deficient and immune-competent hosts, and is providing critical insights into these emerging and reemerging pathogens. This IWOP meeting demonstrated the importance of newly developed genomic level information for many of these pathogens and how analysis of such large data sets is providing key insights into the basic biology of these organisms. A great concern is the loss of scientific expertise and diversity in the research community due to the ongoing decline in research funding. This loss of researchers is due to the small size of many of these research communities and a lack of appreciation by the larger scientific community concerning the state of art and challenges faced by researchers working on these organisms.

    The Istituto di Radioastronomia (IRA) di Bologna and the Osservatorio Astronomico di Cagliari (OAC), on behalf of the European VLBI Consortium, hosted the 12th European VLBI Network (EVN) Symposium and Users Meeting. The Conference was held from 7th to 10th of October at the Hotel Regina Margherita, in the center of Cagliari. The latest scientific results and technical developments from VLBI, and, in particular, e-VLBI and space-VLBI (RadioAstron) outcomes were reported. The timing of this meeting coincided with the first successful observational tests of the Sardinia Radio Telescopes within the EVN, and with a number of results from new and upgraded radio facilities around the globe, such as e-MERLIN, ALMA, and the SKA pathfinders. The symposium was attended by 133 participants from all over the world, with the Asian community represented by more than 20 colleagues. The program of the meeting consisted of 70 oral contributions (including 8 invited speakers) and 50 poster that covered a very wide range of VLBI topics both in galactic and extragalactic astrophysics (e.g., AGN, stellar evolution from birth to death, astrometry, and planetary science) as well as technological developments and future international collaborations. The scientific program also included a visit to the 64-m Sardinia Radio Telescope (SRT) and the EVN Users Meeting, where astronomers have provided useful feedback on various matters regarding EVN operations. The research leading to these results has received funding from the European Commission Seventh Framework Programme (FP/2007-2013) under grant agreement No 283393 (RadioNet3).

    1974-01-01

    A surface heating function, defined as the ratio of the time derivative of the mean annual temperature curve to the surface heat balance, is computed from the annual temperature range and heat balance data for the North American continent. An annual cycle of the surface heat balance is then reconstructed from the surface heating function and the annual temperature curve, and an annual cycle of evaporative plus turbulent heat loss is recomputed from the annual cycles of radiation balance and surface heat balance for the continent. The implications of these results for long range weather forecasting are discussed.

  20. Prospective Associations of 12th-Grade Drinking Intensity and Age 19/20 Driving-Related Consequences.

    The purpose of this study is to examine driving-related consequences associated with levels of drinking intensity among a national sample of young adult drinkers. Data come from a nationally representative sample of 12th graders sampled annually in 2005-2014 with subsamples surveyed at age 19/20 years. Multivariable logistic regressions examined associations of 12th-grade drinking intensity (0-4, 5-9, 10-14, and 15+ drinks in a row) with driving consequences at age 19/20 years. Twelfth-grade binge drinkers (compared with nonbinge drinkers) were more likely to experience negative driving consequences at age 19/20 years. Among binge drinkers, 15+ drinkers (compared with 5-9 drinkers) in 12th grade had increased the risk of negative drinking consequences at age 19/20 years. These results suggest that while underage binge drinkers are at an increased risk for having driving consequences, those who engage in higher intensity drinking are at even greater risk for these consequences. High-intensity drinkers may require additional screening or intervention to reduce future driving-related consequences. Copyright © 2017 Society for Adolescent Health and Medicine.

  1. The BGS magnetic field candidate models for the 12th generation IGRF

    2015-05-01

    We describe the candidate models submitted by the British Geological Survey for the 12th generation International Geomagnetic Reference Field. These models are extracted from a spherical harmonic `parent model' derived from vector and scalar magnetic field data from satellite and observatory sources. These data cover the period 2009.0 to 2014.7 and include measurements from the recently launched European Space Agency (ESA) Swarm satellite constellation. The parent model's internal field time dependence for degrees 1 to 13 is represented by order 6 B-splines with knots at yearly intervals. The parent model's degree 1 external field time dependence is described by periodic functions for the annual and semi-annual signals and by dependence on the 20-min Vector Magnetic Disturbance index. Signals induced by these external fields are also parameterized. Satellite data are weighted by spatial density and by two different noise estimators: (a) by standard deviation along segments of the satellite track and (b) a larger-scale noise estimator defined in terms of a measure of vector activity at the geographically closest magnetic observatories to the sample point. Forecasting of the magnetic field secular variation beyond the span of data is by advection of the main field using core surface flows.

    The North Atlantic Oscillation provides an index of North Atlantic climate variability. The 947-yr long annual resolution record of the North Atlantic Oscillation (NAO) of Trouet et al. (2009, Science, 324, 78-81), the NAO Morocco-Scotland index, combined tree ring and stalagmite data, the latter a single stalagmite growth rate archive from NW Scotland. Trouet et al (2009) noted the unusual persistence of the positive phase of the NAO during the Medieval Climate Anomaly (MCA; 1050-1400AD). In order to better assess the uniqueness of the persistently positive NAO in the MCA, we extend the speleothem portion of the proxy NAO record with a composite of five stalagmites from the same cave system. We present the first-ever composite speleothem growth rate record. Using a combination of lamina counting, U-Th dating, and correlation between growth rate series, we build a continuous, annual-resolution, annually laminated, stalagmite growth rates series for the last 3000 years. We use geostatistical and stochastic approaches appropriate to stalagmite growth rate time series to characterise uncertainty in the stalagmite series and to screen them for periods of relative climate sensitivity vs. periods where there is hydrologically introduced, non-climatic variability. We produce the longest annual-resolution annual lamina record of the NAO for the last 3000 years. The screened stalagmite series is compared to instrumental and proxy records of the NAO. Spectral and wavelet analysis demonstrates that the series contains significant decadal to centennial scale periodicity throughout the record. We demonstrate that the persistently positive NAO during the MCA (1080-1460 CE) is remarkable within the last 3000 years. Two other phases of persistent, positive NAO, occur at 290-550 CE and 660-530 BCE, in agreement with the lower resolution, 5,200-yr Greenland lake sediment NAO proxy (Olsen et al, 2012, Nature Geoscience, 5, 808-812).

    These Proceedings contain the invited and contributed papers presented at the 12th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 8-10 October 2008. As usual, the meeting was held at il Palazzone, a 16th century castle owned by the Scuola Normale Superiore di Pisa. The aim of this biennal conference is to bring together Italian theorists working in various fields of Nuclear Physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to promote collaborations between different groups. There were about 50 participants at the conference, coming from 14 Italian Universities (Cagliari, Catania, Ferrara, Firenze, Genova, Lecce, Milano, Napoli, Padova, Pavia, Pisa, Roma, Trento, Trieste). The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on six main topics: Few-Nucleon Systems, Nuclear Matter and Nuclear Dynamics, Nuclear Astrophysics, Structure of Hadrons and Hadronic Matter, Nuclear Structure, Nuclear Physics with Electroweak Probes. Winfried Leidemann, Maria Colonna, Marcello Lissia, Elena Santopinto, Silvia Lenzi and Omar Benhar took the burden of giving general talks on these topics and reviewing the research activities of the various Italian groups. In addition, 19 contributed papers were presented, most of them by young participants. In the last session of the Conference there were two invited talks related to experimental activities of great current interest. Gianfranco Prete from the Laboratori Nazionali di Legnaro spoke about the Italian radioactive ion beam facility SPES and the status of the European project EURISOL, while Nicola Colonna from the INFN, Bari, gave an overview of the perspectives of development of fourth-generation nuclear reactors. We would like to thank the authors of the general reports for their hard work in reviewing the main achievements in

  7. The intensification and shift of the annual North Atlantic Oscillation in a global warming scenario simulation

    NASA Astrophysics Data System (ADS)

    Hu, Zeng-Zhen; Wu, Zhaohua

    2004-03-01

    The impact of global warming on the annual North Atlantic Oscillation (NAO) is investigated with a global warming scenario simulation of the ECHAM4/OPYC3 coupled general circulation model. It is shown that the annual meridional pressure gradient over the North Atlantic is significantly strengthened, and the two centers of action of the NAO, the Icelandic low and the Azores high, are intensified and shifted northeastward by 10° to 20° in latitude and 30° to 40° in longitude in the global warming scenario. The shift of the centers of action leads to a failure in capturing the NAO change with the traditional definition of the NAO index. A modified index is introduced that allows for this shift, and exhibits a tendency toward the positive phase and an enhancement of its intensity. The intensification of Icelandic low is tied up with zonal mean state change, and the strengthened Azores high is related to the stationary wave change. The shift of the centers of action of the NAO is associated with the stationary wave change.

  3. Forest carbon in North America: annual storage and emissions from British Columbia's harvest, 1965-2065.

    PubMed

    Dymond, Caren C

    2012-07-24

    The default international accounting rules estimate the carbon emissions from forest products by assuming all harvest is immediately emitted to the atmosphere. This makes it difficult to assess the greenhouse gas (GHG) consequences of different forest management or manufacturing activities that maintain the storage of carbon. The Intergovernmental Panel on Climate Change (IPCC) addresses this issue by allowing other accounting methods. The objective of this paper is to provide a new model for estimating annual stock changes of carbon in harvested wood products (HWP). The model, British Columbia Harvested Wood Products version 1 (BC-HWPv1), estimates carbon stocks and fluxes for wood harvested in BC from 1965 to 2065, based on new parameters on local manufacturing, updated and new information for North America on consumption and disposal of wood and paper products, and updated parameters on methane management at landfills in the USA. Based on model results, reporting on emissions as they occur would substantially lower BC's greenhouse gas inventory in 2010 from 48 Mt CO2 to 26 Mt CO2 because of the long-term forest carbon storage in-use and in the non-degradable material in landfills. In addition, if offset projects created under BC's protocol reported 100 year cumulative emissions using the BC-HWPv1 the emissions would be lower by about 11%. This research showed that the IPCC default methods overestimate the emissions North America wood products. Future IPCC GHG accounting methods could include a lower emissions factor (e.g. 0.52) multiplied by the annual harvest, rather than the current multiplier of 1.0. The simulations demonstrated that the primary opportunities for climate change mitigation are in shifting from burning mill waste to using the wood for longer-lived products.

  4. The Annual North American Dendroecological Fieldweek: A workweek in applied tree-ring research

    Trees record many events or processes that influence annual growth patterns. Dendrochronology is concerned with how environment and physiology affect tree growth as recorded within tree rings. The most basic principle of dendrochronology is that of crossdating, in which calendrical years are assigned to individual rings within a tree. Once crossdated, each ring is then a reflection of the climate or other environmental conditions that influenced that tree for that year. The Annual North American Dendroecological Fieldweek is a workweek in applied tree-ring research, designed to give both beginners to the discipline an introduction to its basic methodology and applications and more experienced users a change to work with and learn from others in the field in an informal group setting. The Fieldweek has had an outstanding history to date, with almost 250 participants in the five Fieldweeks from 1990 to 1994. The 6th Fieldweek is scheduled for 30 June to 8 July, 1995, at the Kananaskis Field Station in the Canadian Rockies near Calgary, Alberta.

    New 67-year long (1948-2014) gridded time series of salinity in the North Sea at all depths allowed to quantify, spatially resolved, the amount of inter-annual salinity variability explained by each of its driving mechanisms: sea level pressure (SLP), precipitation, river run-off, zonal and meridional winds and currents over the eastern North Atlantic. For the current data, not only annual averages but also their deviations, as measure of turbulence, were considered. Our results summarize and expand the knowledge gathered in the last 50 years about the mechanisms driving inter-annual variability of salinity in the North Sea. Three mechanisms, uncorrelated with each other and acting over separate regions of the North Sea, arise as most important: (1) River run-off from continental Europe explains 50-80% of inter-annual salinity variations at lag 0 in the Southern and German Bights and the Norwegian Trench up to the connection with the North Atlantic, down to the seabed near the coasts and to the deep Norwegian Trench (100 m); (2) Remote variations of salinity in the Rockall Trough explain 70% of salinity variations of the tongue of high salinity in the northwestern North Sea with a lag of one year and down the water column; (3) The Neva discharge explains 60% of salinity changes in Skagerrak and southern Norwegian trench at lag 0. An explanation for this correlation might be the Baltic freshwater outflow being modulated by the Neva discharge through intensification of the estuarine gravitational circulation. We confirmed known relations between river run-off, precipitation over continental Europe, SLP over northern Europe and zonal wind over western Europe. Linked to these changes, we found also changes of meridional wind north of Scotland favoring eastward Ekman transport of salty North Atlantic waters into the North Sea off the Norwegian coast. Excluding this only case, we found no significant correlation between wind-driven currents and North Sea salinity changes

    Most reconstructions of large scale climate employ Climate Field Reconstruction (CFR) approaches using proxy records, to obtain spatially resolved patterns of past climate change. We test two statistical multivariate methods to reconstruct past SSTs of the North Atlantic Ocean, namely principal component regression (PCR) and canonical correlation analysis (CCA). The locations of our pseudo proxies are based on collection sites of the annually resolved absolutely dated marine proxy Arctica islandica. The different methods are assessed for investigating differences of the CFR that arise using idealized pseudo-proxies and noise-contaminated pseudo-proxies. Moreover, the skill of the CFR was assessed according to different calibration periods and for different networks of pseudo proxy locations within the NA basin. The results indicate that the climate model used as the basis of the pseudoproxy experiment has a more pronounced effect in the reconstruction skill than the calibration period and the method. The noise-contaminated pseudo-proxy experiments are also important for the evaluation of the methods, as larger differences in the spatial patterns of the reconstruction skill become evident. More profound changes were seen between the two statistical methods when the size of the proxy network is smaller than five, making the PCA a more appropriate method for the reconstruction of the NA SSTs. Despite these differences, the results show that the marine network of Arctica islandica can be used to reconstruct skillfully the spatial patterns of SSTs at the eastern North Atlantic basin during the last millennium.

    Characterising how deep-sea communities change on contemporary time-scales and understanding underlying ecosystem processes has become important under changing climate and the rise in the exploitation of deep-sea resources. However, little is known about these dynamics and processes. Long-term observations from which inter-annual variations can be detected are scarce in the deep sea. This study examines inter-annual changes in density, family richness and evenness, family and functional group rank abundance distributions of infaunal polychaetes at two abyssal stations in the North East Pacific (Station M, 1991 to 2005) and in the North East Atlantic (Porcupine Abyssal Plain, 1991 to 1999). The two long-term data sets were used to investigate not only if polychaete community structure and composition varied at inter-annual scales in terms of diversity and rank abundance distributions but also if any changes were related to previous observations in megafauna and environmental factors at each locality. The polychaete community structure at each locality was analysed using univariate statistics as well as multivariate ordination techniques based on Bray-Curtis similarity of the yearly family density. Sub-surface deposit feeders, such as Paraonidae, dominated the North East Pacific, whereas surface deposit feeders, such as Cirratulidae, dominated the North East Atlantic. Both stations showed inter-annual variations in density, family evenness and rank abundance distributions. The greatest changes occurred in 1998 in both time series when polychaete densities peaked, and switches in the rank abundance of the most abundant families and functional groups took place. Inter-annual variations in the polychaete community were correlated with a limited number of holothurian species changes, but no correlation was found with particulate organic matter flux or climate indices. Ecological and environmental factors behind the family-level changes remain elusive. Overall, changes in

  15. Historical changes in the annual number of large floods in North America and Europe

    Many studies have analyzed historical changes in low magnitude floods, such as the annual peak flow, at a national or regional scale. However, the river basins used have often been influenced by human alterations such as reservoir regulation or urbanization. No known studies have analyzed changes in large floods (greater than 25-year return period) at a continental scale for minimally impacted basins. To fill this research gap, this study analyzed flood flows from reference hydrologic networks (RHNs) or RHN-like gauges in North America (United States and Canada) and Europe (United Kingdom, Ireland, France, Spain, Germany, Switzerland, Austria, Iceland, Norway, Denmark, Sweden, and Finland). RHNs are formally defined networks in several countries that comprise gauging stations with a natural or near-natural flow regime and provide good quality data. Selected RHN-like gauges were included following a major effort to ensure RHN-like status through consultation with local experts. Peak flows with recurrence intervals of 25, 50, and 100 years were estimated using consistent methods for over 1200 study gauges, and peak flows at each gauge that exceeded these flood thresholds in the last 40-100 years were compiled. Continental and regional trends over time in the annual number of large floods, with regions differentiated by type of hydrological regime (pluvial, nival, mixed), are being computed and will be presented at AGU. The unique dataset used for this study is an example of successful international collaboration on hydro-climatic data exchange, which is potentially a step towards establishing RHN or RHN-like networks on a global scale. Analysis of flows from such networks would make a valuable contribution to the understanding of historical global hydrological change and would help inform expected future hydrologic changes.

  16. Annual variations in chemical composition of atmospheric precipitation, eastern North Carolina and southeastern Virginia

    1967-01-01

    A 2-year study of precipitation composition over eastern North Carolina and southeastern Virginia has been completed. Chemical analyses were made of the major ions in monthly rainfall samples from each of 12 sampling locations. Areal and seasonal distributions were determined for chloride, calcium, magnesium, sodium, potassium, sulfate, and nitrate. Annual changes in loads and in geographical distribution of sulfate and of nitrate are small. Yearly rainfall sulfate loads amount to approximately 7 tons per square mile, whereas deposition of nitrate is about 2 tons per square mile per year in the interior of the network and less near the coast. Areal patterns of chloride content are consistent with the assumption that the ocean is the only major source of rainfall chloride in the area. Chloride loads were 2.1 and 1.8 tons per square mile per year; the difference can be attributed to meteorological conditions. Cation concentrations in network precipitation appear to depend on localized sources, probably soil dust. Annual loads of the major cations are approximately 2 tons per square mile of calcium, 1.8 tons per square mile of sodium, 0.5 ton per square mile of magnesium, and 0.3 ton per square mile of potassium; considerable year-to-year differences were noted in these values. Bicarbonate and hydrogen ion in network rainfall are closely related to the relative concentrations of sulfate and calcium. Apparently, reaction of an acidic sulfur-containing aerosol with an alkaline calcium source is one of the principal controls on precipitation alkalinity and pH. Ions in precipitation contribute substantially to the quality of surface water in the network area. Comparisons between precipitation input and stream export of ions for four North Carolina rivers show that rainfall sulfate is equal to sulfate discharged, whereas nitrate in rain slightly exceeds stream nitrate. Contributions of cations to the streams by way of precipitation range from about 20 percent for potassium

  17. "Loops and Legs in Quantum Field Theory", 12th DESY Workshop on Elementary Particle Physics

    NASA Astrophysics Data System (ADS)

    The bi-annual international conference "Loops and Legs in Quantum Field Theory" has been held at Weimar, Germany, from April 27 to May 02, 2014. It has been the 12th conference of this series, started in 1992. The main focus of the conference are precision calculations of multi- loop and multi-leg processes in elementary particle physics for processes at present and future high-energy facilities within and beyond the Standard Model. At present many physics questions studied deal with processes at the LHC and future facilities like the ILC. A growing number of contributions deals with important developments in the field of computational technologies and algorithmic methods, including large-scale computer algebra, efficient methods to compute large numbers of Feynman diagrams, analytic summation and integration methods of various kinds, new related function spaces, precise numerical methods and Monte Carlo simulations. The present conference has been attended by more than 110 participants from all over the world, presenting more than 75 contributions, most of which have been written up for these pro- ceedings. The present volume demonstrates in an impressive way the enormous development of the field during the last few years, reaching the level of 5-loop calculations in QCD and a like- wise impressive development in massive next-to-leading order and next-to-next-to-leading order processes. Computer algebraic and numerical calculations require terabyte storage and many CPU years, even after intense parallelization, to obtain state-of-the-art theoretical predictions. The city of Weimar gave a suitable frame to the conference, with its rich history, especially in literature, music, arts, and architecture. Goethe, Schiller, Wieland, Herder, Bach and Liszt lived there and created many of their masterpieces. The many young participants signal that our field is prosperous and faces an exciting future. The conference hotel "Kaiserin Augusta" offered a warm hospitality and

    The High-Tech Plasma Processes - 12th European Plasma Conference (HTPP-12) was held in Bologna (Italy) on 24-29 June 2012. The conference series started in 1990 as a thermal plasma conference and gradually expanded to include other topic fields as well. Now the High-Tech Plasma Processes - European Plasma Conference (HTPP) is a bi-annual international conference based in Europe with topics encompassing the whole area of plasma processing science. The aim of the conference is to bring different scientific communities together, facilitate the contacts between science, technology and industry and provide a platform for the exploration of both fundamental topics and new applications of plasmas. Thanks to the efforts of the conference chairman, Professor Vittorio Colombo and of the co-chair, Professor Piero Favia, a well balanced participation from both the communities of thermal and nonthermal plasma researchers was achieved; this resulted in just about 196 attendees from 39 countries, with 8 plenary and 15 invited talks, plus 50 oral and 140 poster contributions. This volume of Journal of Physics: Conference Series gathers papers from regular contributions of HTPP-12; each contribution submitted for publication has been peer reviewed and the Editors are very grateful to the referees for their careful support in improving the original manuscripts. In the end, 39 manuscripts were accepted for publication, covering different topics of plasma processing science: from plasma fundamentals and modelling to source design and process diagnostics, from nanomaterial synthesis to surface modification, from waste treatment to plasma applications in a liquid environment. It is an honour to present this volume of Journal of Physics: Conference Series and we deeply thank the authors for their enthusiastic and high-grade contribution. Finally, we would like to thank the conference chairmen, the members of the steering committee, the international scientific committee, the local

    Importance The prevalence of underage alcohol use has been studied extensively but binge drinking among youth in the U.S. is not yet well understood. In particular, adolescents may drink much larger amounts than the threshold (5 drinks) often used in definitions of binge drinking. Delineating various levels of binge drinking, including extreme levels, and understanding predictors of such extreme binge drinking among adolescents will benefit public health efforts. Objective To examine the prevalence and predictors of 5+ binge drinking and of 10+ and 15+ extreme binge drinking among 12th graders in the U.S. Design A non-clinical nationally representative sample. Setting High school seniors in the annual Monitoring the Future study between 2005 and 2011. Participants The sample included 16,332 12th graders (modal age 18) in the U.S. Response rates were 79–85%. Main Outcome Measures Prevalence of consuming 5+, 10+, and 15+ drinks in a row in the past two weeks. Results Between 2005 and 2011, 20.2% of high school seniors reported 5+ binge drinking, 10.5% reported 10+ extreme binge drinking, and 5.6% reported 15+ extreme binge drinking in the past 2 weeks. Rates of 5+ binge drinking and 10+ extreme binge drinking have declined since 2005, but rates of 15+ extreme binge drinking have not. Students with college-educated parents were more likely to consume 5+ drinks but less likely to consume 15+ drinks than students whose parents were not college educated. Students from more rural areas were more likely than students from large metropolitan areas to drink 15+ drinks. Socializing with substance-using peers, number of evenings out with friends, substance-related attitudes, and other substance use (cigarettes, marijuana) predicted all three levels of binge and extreme binge drinking. Conclusions Binge drinking at the traditionally defined 5+ drinking level was common among high school seniors representative of all 12th graders in the contiguous U.S. A significant segment of

    2010-09-01

    Since 2003, levels of evidence have been used in the orthopaedic literature to inform the reader of the study quality and its relative significance. Our primary research question was to identify if, since their introduction, there has been an improvement in the levels of evidence of the scientific papers presented at Pediatric Orthopaedic Society of North America (POSNA) meetings. The abstract of every paper presented orally at the POSNA annual meeting were identified for the years 2001, 2002 (pre-2003) and 2007, 2008 (post-2003). In all, 364 abstracts were identified by an independent reviewer who then excluded cadaver, animal, and basic science studies. The 307 included abstracts were then independently blinded and randomized. Two nonepidemiologically trained pediatric orthopaedic fellows independently assigned a study type and level of evidence to each abstract based on the primary research question. The first reviewer reanalyzed 50 randomly selected abstracts. Disagreement was resolved by consensus opinion with an epidemiologically trained pediatric orthopaedic surgeon. The interobserver and intraobserver reliability was calculated for the assignment of study type and levels of evidence. Changes in the study types and levels of evidence were analyzed to compare papers presented pre-2003 and post-2003. For study type and levels of evidence the interobserver reliability between the authors showed substantial agreement (kappa 0.755 and 0.647, respectively). The intraobserver reliability also showed substantial agreement (kappa 0.806 and 0.789, respectively). Comparing pre-2003 and post-2003 studies there were no significant differences between the types of study presented. An increase in the number of level III studies was identified. A decrease in level I and level IV studies was identified. There has been no significant improvement in the scientific quality of studies presented at POSNA Annual Meetings as measured by levels of evidence since their introduction

  10. Discrimination of DPRK M5.1 February 12th, 2013 Earthquake as Nuclear Test Using Analysis of Magnitude, Rupture Duration and Ratio of Seismic Energy and Moment

    2015-04-01

    On February 12th, 2013 morning at 02:57 UTC, there had been an earthquake with its epicenter in the region of North Korea precisely around Sungjibaegam Mountains. Monitoring stations of the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO) and some other seismic network detected this shallow seismic event. Analyzing seismograms recorded after this event can discriminate between a natural earthquake or an explosion. Zhao et. al. (2014) have been successfully discriminate this seismic event of North Korea nuclear test 2013 from ordinary earthquakes based on network P/S spectral ratios using broadband regional seismic data recorded in China, South Korea and Japan. The P/S-type spectral ratios were powerful discriminants to separate explosions from earthquake (Zhao et. al., 2014). Pribadi et. al. (2014) have characterized 27 earthquake-generated tsunamis (tsunamigenic earthquake or tsunami earthquake) from 1991 to 2012 in Indonesia using W-phase inversion analysis, the ratio between the seismic energy (E) and the seismic moment (Mo), the moment magnitude (Mw), the rupture duration (To) and the distance of the hypocenter to the trench. Some of this method was also used by us to characterize the nuclear test earthquake. We discriminate this DPRK M5.1 February 12th, 2013 earthquake from a natural earthquake using analysis magnitude mb, ms and mw, ratio of seismic energy and moment and rupture duration. We used the waveform data of the seismicity on the scope region in radius 5 degrees from the DPRK M5.1 February 12th, 2013 epicenter 41.29, 129.07 (Zhang and Wen, 2013) from 2006 to 2014 with magnitude M ≥ 4.0. We conclude that this earthquake was a shallow seismic event with explosion characteristics and can be discriminate from a natural or tectonic earthquake.

  11. Spectral analysis of air and ground temperatures at Fargo, North Dakota: conduction dominated propagation of the annual frequency signal

    Surface air temperature (SAT) and ground temperature at various depths from 1 cm down to 1170 cm have been observed hourly for approximately the last twenty years at the North Dakota State University (NDSU) Microclimate Research Station (46° 54' N, 96° 48' W, elevation 273 m) in Fargo, North Dakota. Here we aggregate the NDSU SAT data and ground temperature data at each depth into time-series of daily means. We spectrally decompose each temperature time-series into Fourier components and then determine the phase and amplitude of the annual frequency component at each depth. The observed phase and amplitude of the annual signal versus depth are compared to expectations from a model of conductive heat transport in a homogeneous medium. A harmonic temperature signal propagating conductively through a homogeneous medium will display a linear phase shift and an exponential amplitude attenuation with depth. We show that the behavior of the annual frequency signal within the ground is clearly conductive: linear regression of the phase shift and natural logarithm of the amplitude yield fits within R2 values of 0.996 and 0.999, respectively. We use the best-fit regression coefficients from the amplitude and phase shift data to determine an average thermal diffusivity of the soil of 3.7 \\pm 0.1 \\times 10-7 m2/s, and an average wave velocity of the propagating annual signal of 3.3 \\pm 0.5 cm/day.

    To determine the publication rates of podium presentation abstracts at the Arthroscopy Association of North America (AANA) annual scientific meetings from 2004 to 2012. A database of podium presentation abstracts at the annual meetings of the AANA was compiled. Abstract presentations that reached manuscript publication were determined by a PubMed search of the MEDLINE database and Google Scholar. The journal and publication date were then recorded for all identified published abstracts. A total of 658 abstracts were selected for podium presentations at AANA annual meetings from 2004-2012 (range, 53-102 per year). Of these 658 abstracts, 443 (67.3%) went on to eventual publication in peer-reviewed journals. The mean time from the meeting to publication was 20.0 months. Most abstracts were published within 3 years of the meeting (n = 380, 85.8%), with a significant number of published abstracts reaching publication before the time of the meeting (n = 41, 9.3%). Published abstracts were most frequently published in Arthroscopy (n = 186, 42.0%), The American Journal of Sports Medicine (20.3%), and The Journal of Bone and Joint Surgery (6.1%). The overall publication rate of podium presentations at AANA annual meetings (67.3%) was similar to publication rates for other major orthopaedic annual meetings. Most published abstracts (85.8%) were published within 3 years, and the mean time to publication was 20.0 months. The rates of publication of podium presentations at AANA annual meetings show the impact and importance of these meetings in the advancement of orthopaedic research.

    2011-03-21

    Experience with China's 20% energy intensity improvement target during the 11th Five-Year Plan (FYP) (2006-2010) has shown the challenges of rapidly setting targets and implementing measures to meet them. For the 12th FYP (2011-2015), there is an urgent need for a more scientific methodology to allocate targets among the provinces and to track physical and economic indicators of energy and carbon saving progress. This report provides a sectoral methodology for allocating a national energy intensity target - expressed as percent change in energy per unit gross domestic product (GDP) - among China's provinces in the 12th FYP. Drawing on international experience - especially the European Union (EU) Triptych approach for allocating Kyoto carbon targets among EU member states - the methodology here makes important modifications to the EU approach to address an energy intensity rather than a CO{sub 2} emissions target, and for the wider variation in provincial energy and economic structure in China. The methodology combines top-down national target projections and bottom-up provincial and sectoral projections of energy and GDP to determine target allocation of energy intensity targets. Total primary energy consumption is separated into three end-use sectors - industrial, residential, and other energy. Sectoral indicators are used to differentiate the potential for energy saving among the provinces. This sectoral methodology is utilized to allocate provincial-level targets for a national target of 20% energy intensity improvement during the 12th FYP; the official target is determined by the National Development and Reform Commission. Energy and GDP projections used in the allocations were compared with other models, and several allocation scenarios were run to test sensitivity. The resulting allocations for the 12th FYP offer insight on past performance and offer somewhat different distributions of provincial targets compared to the 11th FYP. Recommendations for reporting

  16. The annual cycle of gross primary production, net community production, and export efficiency across the North Pacific Ocean

    We measured triple oxygen isotopes and oxygen/argon dissolved gas ratios as nonincubation-based geochemical tracers of gross oxygen production (GOP) and net community production (NCP) on 16 container ship transects across the North Pacific from 2008 to 2012. We estimate rates and efficiency of biological carbon export throughout the full annual cycle across the North Pacific basin (35°N-50°N, 142°E-125°W) by constructing mixed layer budgets that account for physical and biological influences on these tracers. During the productive season from spring to fall, GOP and NCP are highest in the Kuroshio region west of 170°E and decrease eastward across the basin. However, deep winter mixed layers (>200 m) west of 160°W ventilate ~40-90% of this seasonally exported carbon, while only ~10% of seasonally exported carbon east of 160°W is ventilated in winter where mixed layers are <120 m. As a result, despite higher annual GOP in the west than the east, the annual carbon export (sequestration) rate and efficiency decrease westward across the basin from export of 2.3 ± 0.3 mol C m-2 yr-1 east of 160°W to 0.5 ± 0.7 mol C m-2 yr-1 west of 170°E. Existing productivity rate estimates from time series stations are consistent with our regional productivity rate estimates in the eastern but not western North Pacific. These results highlight the need to estimate productivity rates over broad spatial areas and throughout the full annual cycle including during winter ventilation in order to accurately estimate the rate and efficiency of carbon sequestration via the ocean's biological pump.

    Understanding how coastal sea level relates to the variableocean circulation, and parsing out the relative contributions of stericheight (ocean density) and bottom pressure (ocean mass), is crucial forinterpreting tide gauge records and projecting sea level rise. Here,annual sea level data from tide gauge records along the NorthAmerican northeast coast over 1980-2010 are considered. The data recordsare adjusted for the inverted barometer effect and compared to a set of data-assimilating "ocean reanalysis" products, whichsimulate both ocean mass and steric contributions to sea level changes, aswell as a global barotropic model solution, which simulates only the oceanmass contribution. North of Cape Hatteras, the barotropic model shows asmuch (if not more) skill than ocean reanalyses, explaining 50% of thevariance in the adjusted annual tide gauge sea level records,demonstrating the importance of local ocean mass changes. Additionalnumerical experiments show that the annual ocean mass changes along thiscoast from the barotropic model are driven by local wind stress over thecontinental shelf and slope. This result is interpreted in the light of asimple dynamic framework, wherein bottom friction balances surface windstress in the alongshore direction and geostrophy holds in theacross-shore direction. Results highlight the importance of barotropicocean dynamics and ocean mass redistribution on coastal sea level changeson interannual and decadal time scales. They also have implications fordiagnosing the uncertainties in current ocean reanalysis, using tide gaugerecords to infer past changes in ocean circulation, as well as identifyingthe physical mechanisms responsible for projected future regional sealevel rise.

    1995-12-31

    The North American Association for Environmental Education (NAAEE) is a network of professionals and students working in the field of environmental education throughout North America and in 40 countries around the world. For almost 25 years, the Association has promoted EE and supported the work of environmental educators. There are many environmental interest groups, and many organizations dedicated to the improvement of education. NAAEE uniquely combines and integrates both of these perspectives, and takes a cooperative, nonconfrontational approach to promoting education about environmental issues. NAAEE recognizes the need for a coherent body of information about environmental issues. Its members also recognize that information and analysis are only part of an effective education program. To be truly effective, this body of knowledge must be integrated into all aspects of the curriculum and into all types of educating institutions for the widest array of audiences. In order to translate theory into reality, and provide tangible support for EE and environmental educators, NAAEE engages in a variety of programs and activities. Some examples are the annual conference at varying North American sites, and active publications program, the Environmental Education Training Institute, the VINE (Volunteer-led Investigations of Neighborhood Ecology) Network, the Environmental Issues Forums (EIF) program, and the NAAEE Skills Bank. Each year at its annual conference, NAAEE holds a Curriculum and Resources Fair where conference participants can examine EE materials submitted to NAAEE. This listing contains descriptions of all entries that NAAEE received for the 1995 Fair.

    Using a propensity score matching method and regression modeling based on the 2002 Education Longitudinal Study, this study found a significant Catholic school effect on mathematics achievement among those 12th graders who were least likely to attend Catholic school. This result is evident within-districts after we used the School District Demographics System map data to locate Catholic schools within school district boundaries. Furthermore, the Catholic school effects were statistically significant for students in districts that allowed publicly funded private education. PMID:25606028

    The 12th International Conference on Human Retrovirology: HTLV and Related Retroviruses, was held at the Half Moon Hotel in Montego Bay, Jamaica, from June 22nd to June 25th 2005. The scientific conference, sponsored by the International Retrovirology Association, is held biennially at rotating international venues around the world. The meeting brings together basic scientists, epidemiologists and clinical researchers to discuss findings to prevent HTLV infection or develop new therapies against HTLV-mediated diseases. The Association fosters the education and training of young scientists to bring new approaches to the complex problems of HTLV research, such as translational research to bring findings from the laboratory into clinical trials that benefit HTLV-infected patients. The breadth and quality of research presentations and workshops at the 12th International Conference indicate that these goals are being accomplished. As HTLV research enters its third decade a new generation of scientists face many challenges. However, HTLV scientists and clinicians displayed exciting new approaches and discoveries during plenary talks and poster sessions. The conference encouraged research in HTLV infections and disease, fostered collaborations, and stimulated new partnerships between clinicians and scientists to encourage clinical trials and novel therapeutic interventions.

    We evaluated whether annual adult survival of Least Auklets (Aethia pusilla), a small planktivorous seabird, covaried with large-scale oceanographic conditions in the North Pacific ocean during 1990-2000. Adult Least Auklets (n=358 total) were captured near their nest sites, marked with plastic color bands, and survival estimates were based on color band resightings at their breeding colony. Survival estimates and relationships between survival and three large-scale indices of climatic conditions that correlate with oceanography: the Pacific Decadal Oscillation Index (PDO), Aleutian Low Pressure Index (ALPI), and North Pacific Index (NPI) were evaluated using program MARK. The best models included: (1) two groups of birds, defined by ease of resighting, that differed in recapture rate (p) but not survival rate (φ); and (2) models that allowed for survival rates to differ in the year immediately after first capture from all subsequent years (structurally an age-model). Both of these model structures effectively explained (i.e. removed) sources of heterogeneity in the data set. For Least Auklet survival, the best fitting model was a two-age model incorporating the covariate NPI (average value for the period auklets were at sea, August - April), [φ(age1, age2×NPI), p(g)]. The annual survival rate varied from 0.747±0.075 SE in 1992-1993 to 0.953±0.052 in 1991-1992 (based on the model [φ(age1, age2×t), p(g)]) and averaged 0.873±0.037 over the study period. Least Auklet annual survival covaried with continuous variation in large-scale climatic conditions. Our results point to oceanographic conditions that relate to climate change as crucial to the status of auklet populations, notwithstanding conservation measures taken to control introduced predators, oil spills, human disturbance and other anthropogenic sources of mortality.

    The region of North Eastern North America is located in a privileged geographical position that allows for interesting relationships between various large-scale circulation modes and the seasonal surface wind. This is a region where the large-scale configurations foster the transit of tropical cyclonic events during the summer season and even more intense extratropical cyclones during winter. In this work we present a statistical downscaling method based on Canonical Correlation Analysis (CCA) that exploits the relationships among the main modes of circulation over the North Atlantic and Pacific Sectors and the behaviour of surface wind. The statistical technique has been implemented with predictor variables (mean sea level pressure and geopotential height at different levels) provided by all the reanalysis products available to date. The regional scale data consist of a set of 526 sites distributed over North Eastern North America that span over a period of about 60 years (1953-2010). These data have been previously subjected to an exhaustive quality control process, height standardization and wind direction homogenization. Several decades of observations allow for the study of intra to multidecadal variability. Also, the sensitivity of the downscaling methodology to the selection of a systematic sampling of model parameter values has been explored. The statistical relationship obtained by this method also allows for the reconstruction of the regional wind behaviour back to the mid 19th century through various 20th century reanalysis and instrumental sea level pressure datasets.

    Spatial diversity patterns are thought to be driven by climate-mediated processes. However, temporal patterns of community composition remain poorly studied. We provide two complementary analyses of North American mammal diversity, using (i) a paleontological dataset (2077 localities with 2493 taxon occurrences) spanning 21 discrete subdivisions of the Cenozoic based on North American Land Mammal Ages (36 Ma – present), and (ii) climate space model predictions for 744 extant mammals under eight scenarios of future climate change. Spatial variation in fossil mammal community structure (β diversity) is highest at intermediate values of continental mean annual precipitation (MAP) estimated from paleosols (∼450 mm/year) and declines under both wetter and drier conditions, reflecting diversity patterns of modern mammals. Latitudinal gradients in community change (latitudinal turnover gradients, aka LTGs) increase in strength through the Cenozoic, but also show a cyclical pattern that is significantly explained by MAP. In general, LTGs are weakest when continental MAP is highest, similar to modern tropical ecosystems in which latitudinal diversity gradients are weak or undetectable. Projections under modeled climate change show no substantial change in β diversity or LTG strength for North American mammals. Our results suggest that similar climate-mediated mechanisms might drive spatial and temporal patterns of community composition in both fossil and extant mammals. We also provide empirical evidence that the ecological processes on which climate space models are based are insufficient for accurately forecasting long-term mammalian response to anthropogenic climate change and inclusion of historical parameters may be essential.

    This study aimed to identify the sequential patterns of drug use initiation, which included prescription drugs misuse (PDM), among 12th-grade students in Indiana. The study also tested the suitability of the data mining method Market Basket Analysis (MBA) to detect common drug use initiation sequences in large-scale surveys. Data from 2007 to 2009 Annual Surveys of Alcohol, Tobacco, and Other Drug Use by Indiana Children and Adolescents were used for this study. A close-ended, self-administered questionnaire was used to ask adolescents about the use of 21 substance categories and the age of first use. "Support%" and "confidence%" statistics of Market Basket Analysis detected multiple and substitute addictions, respectively. The lifetime prevalence of using any addictive substance was 73.3%, and it has been decreasing during past few years. Although the lifetime prevalence of PDM was 19.2%, it has been increasing. Males and whites were more likely to use drugs and engage in multiple addictions. Market Basket Analysis identified common drug use initiation sequences that involved 11 drugs. High levels of support existed for associations among alcohol, cigarettes, and marijuana, whereas associations that included prescription drugs had medium levels of support. Market Basket Analysis is useful for the detection of common substance use initiation sequences in large-scale surveys. Before initiation of prescription drugs, physicians should consider the adolescents' risk of addiction. Prevention programs should address multiple addictions, substitute addictions, common sequences in drug use initiation, sex and racial differences in PDM, and normative beliefs of parents and adolescents in relation to PDM.

    Retrospective review of conference abstracts. To determine the publication rate of podium and poster presentations at the 2010-2012 North American Spine Society (NASS) annual meetings. Presentations at medical conferences are utilized to disseminate new clinical information. The orthopaedic literature estimates the rate of publication for abstracts presented at major meetings to be between 34.0-67.1%. However, few studies have analyzed the publication rate of accepted abstracts to the NASS annual meetings. All abstracts presented at the 2010-2012 NASS annual meetings were reviewed. PubMed and Google Scholar databases were searched to determine if each abstract was published as a full-length manuscript before or up to 3 years after its NASS meeting presentation. Statistical analyses included descriptive statistics, poisson regression with robust error variance, and linear regression. A total of 1045 abstracts were accepted to the 2010-2012 NASS annual meetings. 43.8% were published before or up 3 years after their NASS presentation. Podium presentations were more likely to be published than poster presentations (47.1% vs. 37.7%, p = 0.005). Abstracts with "Best" or "Outstanding" designations were also more likely to be published than abstracts without those designations (54.4% vs. 45.0%, p = 0.034). Presentations designated as "Best" or "Outstanding" papers had shorter time to publication than presentations without those designations (369 vs 486 days, p = 0.002). This study suggests that only 43.8% of abstracts accepted to NASS are published as full-length manuscripts. As such, practitioners should use caution when altering clinical practice based solely on conference presentations. Additionally, podium presentations are more likely to be published than poster presentations. This trend may be reflective of the higher quality of abstracts accepted as podiums, or may be associated with a larger number of lower quality abstracts being accepted due to the

    The Manchester Microlensing Conference (M2C) was held at the Jodrell Bank Centre for Astrophysics at Manchester University in the UK from 21st-25th January 2008. M2C comprised two elements: the ANGLES Microlensing Workshop and the 12th International Conference on gravitational microlensing. M2C began with the two-day Workshop, providing interactive Master Classes to around 60 researchers on selected hot topics in microlensing. The Master Classes were delivered by world-leading experts on each of the topics. The topics reflected the diverse techniques and applications of microlensing, such as crowded-field photometry, modelling of extra-solar planetary systems, and the use of microlensing in cosmology. The 12th International Conference on microlensing followed immediately after the Workshop and was attended by around 90 researchers. The Conference covered all aspects of current research in microlensing, including: Microlensing towards the Magellanic Clouds; Cosmological Microlensing; Stellar and Galactic Microlensing; Galactic Microlensing Surveys; Follow-up Programmes and Planetary Microlensing; M31 Microlensing; and Future Directions. The M2C Proceedings serve three functions. Through the expert master classes the M2C Proceedings provide a great starting point for those who wish to enter the field or who just wish to learn more about microlensing at a depth beyond that usually covered by a single review article. The M2C proceedings also provide a snapshot of the state-of-the art in microlensing observations and theory as of January 2008, in what is a rapidly developing field. Lastly, the M2C meeting and its Proceedings are dedicated to the memory of the late Bohdan Paczynski, a towering figure and founding father of modern day microlensing research.

    In order to investigate the future trends of SO2 and NOx pollution in Guiyang city of China, the MM5/CALMET/CALPUFF modeling system is applied to assess the effects of air pollution improvement that would result from reduction targets for SO2 and NOx emissions during the 12th Five-Year Plan (2011-2015). Three scenarios are established for the objective year 2015 based on the reference emissions in base year 2010. Scenario analysis and modeling results show that emissions are projected to increase by 26.5% for SO2 and 138.0% for NOx in 2015 Business-As-Usual (BAU) relative to base year 2010, respectively, which will lead to a substantial worsening tendency of SO2 and NOx pollution. In comparison, both the 2015 Policy Reduction (PR) and 2015 Intensive Policy Reduction (IPR) scenarios would contribute to improve the urban air quality. Under 2015 PR scenario, the maximum annual average concentration of SO2 and NOx will reduce by 54.9% and 31.7%, respectively, relative to the year 2010, with only 2.1% of all individual gridded receptors exceed the national air quality standard limits; while the maximum annual average concentrations of SO2 and NOx can reduce further under 2015 IPR scenario and comply well with standards limits. In view of the technical feasibility and cost-effectiveness, the emission reduction targets set in the 2015 PR scenario are regarded as more reasonable in order to further improve the air quality in Guiyang during the 12th FYP period and a series of comprehensive countermeasures should be effectively implemented.

  17. Stochastic models and spectra of interannual variability of mean annual sea surface temperature in the North Atlantic

    Estimates of one- and two-variate autoregressive models of mean annual sea surface temperature (SST) in five Smed squares in the North Atlantic are obtained by analysing time series of SST, 1881-1970. Year-to-year variations of SST are shown to follow the AR model of order one with a regression parameter of 0.5 so that their generalized spectrum decreases monotonically and relatively fast with frequency while the limits of statistical predictability amount up to two years. Two-variate models of SST reveal frequency-dependent time lags up to three years and possess slightly better statistical predictability. A feedback in the system of warm and cold currents is found with a characteristic time scale of about six years, which plays an important role in the system's energy budget.

  18. Forest carbon in North America: annual storage and emissions from British Columbia’s harvest, 1965–2065

    PubMed Central

    2012-01-01

    Background The default international accounting rules estimate the carbon emissions from forest products by assuming all harvest is immediately emitted to the atmosphere. This makes it difficult to assess the greenhouse gas (GHG) consequences of different forest management or manufacturing activities that maintain the storage of carbon. The Intergovernmental Panel on Climate Change (IPCC) addresses this issue by allowing other accounting methods. The objective of this paper is to provide a new model for estimating annual stock changes of carbon in harvested wood products (HWP). Results The model, British Columbia Harvested Wood Products version 1 (BC-HWPv1), estimates carbon stocks and fluxes for wood harvested in BC from 1965 to 2065, based on new parameters on local manufacturing, updated and new information for North America on consumption and disposal of wood and paper products, and updated parameters on methane management at landfills in the USA. Based on model results, reporting on emissions as they occur would substantially lower BC’s greenhouse gas inventory in 2010 from 48 Mt CO2 to 26 Mt CO2 because of the long-term forest carbon storage in-use and in the non-degradable material in landfills. In addition, if offset projects created under BC’s protocol reported 100 year cumulative emissions using the BC-HWPv1 the emissions would be lower by about 11%. Conclusions This research showed that the IPCC default methods overestimate the emissions North America wood products. Future IPCC GHG accounting methods could include a lower emissions factor (e.g. 0.52) multiplied by the annual harvest, rather than the current multiplier of 1.0. The simulations demonstrated that the primary opportunities for climate change mitigation are in shifting from burning mill waste to using the wood for longer-lived products. PMID:22828161

  19. Climatic Effects on the Inter-Annual Variability of Carbon Fluxes for North America and Europe

    The connection between climate variability and global carbon cycle has already been shown to be linked with the North Atlantic Oscillation (NAO) (1). A positive phase of the NAO is associated with more and stronger winter storms crossing the North Atlantic on a more northerly route, causing major anomalies in sea surface temperature, currents and convective activity throughout the North Atlantic. A long-term trend towards very positive values has culminated in the early 1990s, and since then a decreasing trend is happening (1). Identification of the climatic drivers of the net ecosystem fluxes is becoming a rising issue. In particular the effects of year-to-year climate variability on regional budgets and the understanding of the underlying biogeochemical processes are of fundamental importance due to the intensification of extreme climatic events like precipitation (2) and drought events (3). We identified the relations between climatic variability (i.e. NAO) and the regional carbon budgets of North America and Europe over the period from 1989 to 2008. In doing this we kept special focus both on temporal and spatial scale. For this purpose we took advantage of the high-density of FLUXNET measurement sites in these areas. We applied a radiation use efficiency model for gross primary production (4) combined with a semi-empirical total ecosystem respiration model (5). As drivers for the model we used climatic and fraction of absorbed photosynthetically active radiation (FPAR) records. We utilized in-situ calibrated model parameters to estimate the regional ecosystem carbon fluxes. The model was spatially applied according to the similarity in the climatic-phenological space of each grid pixel with the measurement site to which it was calibrated (e.g., 6). We found that for Europe NAO could explain NEE variability in a reasonable way for northern and southern Europe, but for the mid-latitude region this was not the case. For North America the patterns were less clear

  20. An annually-resolved marine radiocarbon bomb-pulse compilation from the temperate North Atlantic using long-lived molluscs (Arctica islandica)

    Radiocarbon measurements from increments of annually-banded corals covering the past 60 years from sub-tropical and tropical contexts provide valuable records of the marine expression of the atmospheric excess radiocarbon "bomb-pulse" due to post-war nuclear weapons tests. These records can be used as calibration series for high-resolution post-bomb marine radiocarbon dating and constitute tracers for identifying watermass age and mixing processes. Until now, such applications have been restricted in temperate shelf seas because of the lack of widespread measurements from annually-resolved archives. Here we present a compilation of bomb-pulse data from annual growth increments of the bivalve mollusc Arctica islandica from relatively shallow sites (< 200 m) across the temperate North Atlantic (Georges Bank, north Icelandic shelf, north Norway, North Sea). The temporal response is highly correlated at all sites, but the amplitude of the bomb-pulse varies, with the highest values attained in the North Sea and the most damped response on the north Icelandic shelf. These differences can be attributed to the integrated hydrographic context of these sites (entrainment of deep, old water; rates of air-sea exchange; fluvial runoff; removal of high radiocarbon level surface waters through north Atlantic deep water formation). The north Icelandic data contain a reversal in the rising limb of the bomb-pulse which is not present elsewhere, even in the more sensitive sites. This reversal is coincident with instrumental data characterising the Great Salinity Anomaly of the 1960s when cold, relatively fresh, and old (with respect to radiocarbon; Delta R = + 200 years) waters of the East Icelandic Current flooded the north Icelandic shelf as a result of southward migration of the Polar Front. However this reversal may also be a result of the short hiatus in bomb testing in the late 1950s. The evolution of bomb-pulse data will be discussed as well as other potential applications of

    There is an increasing demand for assessment of water provisioning ecosystem services. While simple models with low data and expertise requirements are attractive, their use as decision-aid tools should be supported by uncertainty characterization. We assessed the performance of the InVEST annual water yield model, a popular tool for ecosystem service assessment based on the Budyko hydrological framework. Our study involved the comparison of 10 subcatchments ranging in size and land-use configuration, in the Cape Fear basin, North Carolina. We analyzed the model sensitivity to climate variables and input parameters, and the structural error associated with the use of the Budyko framework, a lumped (catchment-scale) model theory, in a spatially explicit way. Comparison of model predictions with observations and with the lumped model predictions confirmed that the InVEST model is able to represent differences in land uses and therefore in the spatial distribution of water provisioning services. Our results emphasize the effect of climate input errors, especially annual precipitation, and errors in the ecohydrological parameter Z, which are both comparable to the model structure uncertainties. Our case study supports the use of the model for predicting land-use change effect on water provisioning, although its use for identifying areas of high water yield will be influenced by precipitation errors. While some results are context-specific, our study provides general insights and methods to help identify the regions and decision contexts where the model predictions may be used with confidence.

    This study compared physical activity, sedentary behaviors, and other health indicators between 1381 employed and nonemployed 12th grade girls. The girls were from 22 high schools in South Carolina (2002-2003); 56% of the girls were African American, and the mean age was 17.7 (0.6) years. Physical activity and sedentary behaviors were measured using the 3-Day Physical Activity Recall (3DPAR). Fitness, depressive symptoms, and smoking behavior were assessed. Fifty percent of the girls were employed, and on average, employed girls worked 9.6 30-minute blocks per day. Girls who worked reported significantly (p < or = 0.001) higher average total metabolic equivalents (METs) (mean [M] 66.4, SE 0.5) than girls who did not work (M 59.5, SE 0.5). Also, a higher percent of girls who worked reported 2+ blocks of moderate to vigorous physical activity (MVPA) (89.3%), and fewer (20.2%) reported 4+ blocks of electronic media (EM) compared with girls who did not work (MVPA 62.7%, EM 41.7%). After on-the-job activity was subtracted, total METs for girls who worked was reduced to 48.0 (SE 0.4), and only 48.5% reported 2 or more blocks on average of MVPA. No significant differences (p > 0.05) were found between girls who reported working (W) and those who did not (NW) for body mass index (BMI) (W: M 25.2, SE 0.2; NW: M 24.6, SE 0.2), depression scores (W: M 14.4, SE 0.5; NW: M 14.4, SE 0.5), fitness (W: M 11.3 kg . m/min/kg, SE 0.2; NW: M 11.7 kg . m/min/kg, SE 0.2), or smoking during the past 30 days (W: 18.5%; NW: 17.4%). Nearly one third of employed high school girls' total physical activity occurred while they were at work. Employed girls also spent less time using electronic media. Employment was not associated with fitness, smoking, or depressive symptoms in 12th grade girls.

    Health care reform with the Affordable Care Act aims to control health care costs, in part, through the use of comparative effectiveness research and quality of care measures. Bladder cancer is one of the most expensive malignancies to manage as related to the need for continuous monitoring and the treatment of recurrence. The use of clinical practice guidelines relying on evidence based medicine in the management of patients with bladder cancer will help to ensure quality of care and cost containment. The goal of session I was to provide a thorough discussion of the quality of care and cost issues related to bladder cancer including an examination of levels of evidence, implementation and compliance with clinical practice guidelines, the use of standardized reporting methodologies, and comparative effectiveness research. Bladder cancer is a common malignancy with a variable biology and natural history. Although the majority of patients are diagnosed with non-invasive disease, approximately 20-40% of patients either present with or develop more advanced disease. The 5-year survival for patients with lymph node involvement at the time of surgery is 20-30% and patients with metastatic disease treated with chemotherapy have a median survival of only 15 months. Novel approaches for the management of patients with bladder cancer are desperately needed. The goal of session II was to review the current state of translational research in bladder cancer as related to both early and late stage disease including a discussion of novel molecular targets and targeted therapeutics, pharmacogenomics to predict response to therapy, and exploring the role for agents targeting angiogenesis.

    The 12th International Workshop on H-mode Physics and Transport Barriers was held at the Princeton Plasma Physics Laboratory, Princeton, New Jersey, USA between September 30 and October 2, 2009. This meeting was the continuation of a series of previous meetings which was initiated in 1987 and has been held bi-annually since then. Following the recent tradition at the last few meetings, the program was sub- divided into six sessions. At each session, an overview talk was presented, followed by two or three shorter oral presentations which supplemented the coverage of important issues. These talks were followed by discussion periods and poster sessions of contributed papers. The sessions were: Physics of Transition to/from Enhanced Confinement Regimes, Pedestal and Edge Localized Mode Dynamics, Plasma Rotation and Momentum Transport, Role of 3D Physics in Transport Barriers, Transport Barriers: Theory and Simulations and High Priority ITER Issues on Transport Barriers. The diversity of the 90 registered participants was remarkable, with 22 different nationalities. US participants were in the majority (36), followed by Japan (14), South Korea (7), and China (6). This special issue of Nuclear Fusion consists of a cluster of 18 accepted papers from submitted manuscripts based on overview talks and poster presentations. The paper selection procedure followed the guidelines of Nuclear Fusion which are essentially the same as for regular articles with an additional requirement on timeliness of submission, review and revision. One overview paper and five contributed papers report on the H-mode pedestal related results which reflect the importance of this issue concerning the successful operation of ITER. Four papers address the rotation and momentum transport which play a crucial role in transport barrier physics. The transport barrier transition condition is the main focus of other four papers. Finally, four additional papers are devoted to the behaviour and control of

    Radiocarbon measurements from increments of annually-banded corals covering the past 60 years from sub- tropical and tropical contexts provide valuable records of the marine expression of the atmospheric excess radiocarbon "bomb-pulse". These records can be used as calibration series for high-resolution post- bomb radiocarbon dating and constitute tracers for identifying watermass age and mixing processes. Hitherto such applications have been restricted in temperate shelf seas because of the lack of widespread measurements from annually-resolved archives. Here we present a compilation of bomb-pulse data from annual growth increments of the shallow marine bivalve mollusc Arctica islandica from sites across the temperate North Atlantic (Georges Bank, north Icelandic shelf, north Norway, North Sea). The temporal response is highly correlated at all sites, but the amplitude of the bomb-pulse varies, with the highest values attained in the North Sea and the most damped response on the north Icelandic shelf. These differences can be attributed to the integrated hydrographic context of these sites (entrainment of deep, old water; rates of air-sea exchange; fluvial runoff). The north Icelandic data contain a reversal in the rising limb of the bomb- pulse which is not present elsewhere, even in the more sensitive sites. This reversal correlates with instrumental data characterising the Great Salinity Anomaly of the 1960s when old (deltaR = + 200 years), cold and relatively fresh East Icelandic Current flooded the north Icelandic shelf as a result of southward migration of the Polar Front. The bomb-pulse radiocarbon proxy is therefore a sensitive proxy for hydrographic variability. Further applications of these data will be discussed.

    In the paper, we present a study of three homologous H flares observed on 12th June 2000 in active region (AR) NOAA 9033. During the observation of AR NOAA 9033 on 12th June 2000, we observed 1st solar flare between 0135-0155 UT, 2nd flare between 0236-0253 UT and 3rd flare between 0259-0323 UT. The present study supports the quadrapolar reconnection scenario presented by Machado et al. (1983) and also shows the presence of 26.7 min periodicity in intensity data estimated from the site of the homologous flares.

    Using the approaches of history of the present, this article recovers the discussions surrounding the 12th International Conference on Cancer carried out in Buenos Aires in 1978, in reaction to which Georges Périès organized a "counter-conference" in Paris. In order to understand this discussion, the political situation of the time is described, as is the state of human rights at the time in Argentina, the role of the media - in particular the newspapers La Nación and Clarín and the magazine Gente - and the institutional position adopted by the National Academy of Medicine, as expressed in a letter sent to the presidents of the primary scientific societies of the world. The letter is reprinted in this text as a documentary source, taken from Memoria: Año 1978 (Presidencia de Dr. José E. Rivarola) [Acta: Year 1978 (Presidency of Dr. José E. Rivarola)]. The framework of the discussion makes reference to science's social policy versus science's supposed neutrality and the role of scientific societies.

    The 12th Europhysical Conference on Defects in Insulating Materials (EURODIM14) was held at the University of Kent, UK, from 13-18 July 2014. It was attended by about 120 delegates from around the world, and featured 56 oral presentations and 77 posters. EURODIM14 followed other conferences in the series, held in Pecs (2010), Milan (2006) and Wroclaw (2002), as well as the related ICDIM conferences held in Santa Fe (2012), Aracaju (2008) and Riga (2004). These conferences all have the aim of bringing together scientists to discuss the chemistry and physics of defects in solids, and their role in determining material properties. We would like to thank the International Advisory Committee for suggesting invited speakers, and the Local and Programme Committee for their hard work in planning and running the conference. Finally we would like to thank the authors and referees for their contributions to the proceedings. M L Alfredsson (Conference Chair) A V Chadwick R A Jackson E E McCabe

    Weaver, J. Curtis

    2006-01-01

    A study of annual maximum precipitation frequency in Mecklenburg County, North Carolina, was conducted to characterize the frequency of precipitation at sites having at least 10 years of precipitation record. Precipitation-frequency studies provide information about the occurrence of precipitation amounts for given durations (for example, 1 hour or 24 hours) that can be expected to occur within a specified recurrence interval (expressed in years). In this study, annual maximum precipitation totals were determined for durations of 15 and 30 minutes; 1, 2, 3, 6, 12, and 24 hours; and for recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. Precipitation data collected by the U.S. Geological Survey network of raingages in the city of Charlotte and Mecklenburg County were analyzed for this study. In September 2004, more than 70 precipitation sites were in operation; 27 of these sites had at least 10 years of record, which is the minimum record typically required in frequency studies. Missing record at one site, however, resulted in its removal from the dataset. Two datasets--the Charlotte Raingage Network (CRN) initial and CRN modified datasets--were developed from the U.S. Geological Survey data, which represented relatively short periods of record (10 and 11 years). The CRN initial dataset included very high precipitation totals from two storms that caused severe flooding in areas of the city and county in August 1995 and July 1997, which could significantly influence the statistical results. The CRN modified dataset excluded the highest precipitation totals from these two storms but included the second highest totals. More...

  20. Intra-seasonal and Inter-annual variability of Bowen Ratio over rain-shadow region of North peninsular India

    Intra-seasonal and inter-annual variability of Bowen Ratio (BR) have been studied over the rain-shadow region of north peninsular India during summer monsoon season. Daily grid point data of latent heat flux (LHF), sensible heat flux (SHF) from NCEP/NCAR Reanalysis for the period 1970-2014 have been used to compute daily area-mean BR. Daily grid point rainfall data at a resolution of 0.25° × 0.25° from APHRODITE's Water Resources for the available period 1970-2007 have been used to study the association between rainfall and BR. The study revealed that BR rapidly decreases from 4.1 to 0.29 in the month of June and then remains nearly constant at the same value (≤0.1) in the rest of the season. High values of BR in the first half of June are indicative of intense thermals and convective clouds with higher bases. Low values of BR from July to September period are indicative of weak thermals and convective clouds with lower bases. Intra-seasonal and inter-annual variability of BR is found to be inversely related to precipitation over the region. BR analysis indicates that the land surface characteristics of the study region during July-September are similar to that over oceanic regions as far as intensity of thermals and associated cloud microphysical properties are concerned. Similar variation of BR is found in El Nino and La Nina years. During June, an increasing trend is observed in SHF and BR and decreasing trend in LHF from 1976 to 2014. Increasing trend in the SHF is statistically significant.

    Emerging contaminants (ECs) such as endocrine-disrupting chemicals (EDCs) and pharmaceuticals and personal care products (PPCPs) attracted global concern during the last decades due to their potential adverse effects on humans and ecosystems. This work is the first study to assess the spatiotemporal changes, annual fluxes and ecological risk of ECs (4 EDCs and 6 PPCPs) by different monitoring strategies (spot and passive sampling) over 12 months in a Scottish priority catchment (River Ugie, Scotland, 335 km(2)). Overall, the total concentration in water ranged from annual fluxes of 4 EDCs transported to the Ugie estuary and North Sea were estimated to be 409 and 294 g based on the spot and passive sampling data, respectively, while they were 4636 and 4517 g for 6 PPCPs by spot and passive sampling, respectively. The spatiotemporal trend suggested that human activities and medication usages were the primary source of the contaminants. The overall comparison of the two sampling strategies supported the hypothesis that passive sampling tends to integrate the contaminants over a period of exposure and allows quantification of contamination at low concentration. The ecological risk assessment showed that bisphenol A posed the highest risks with 21.5% of the spot samples, resulting in a risk quotient >1. This suggests that mitigation measures might need to be taken to reduce the input of emerging contaminants into the river and its adjacent estuary and sea.

    Purpose To investigate the relationship between proximity to commercial physical activity facilities and cardiorespiratory fitness of 12th grade girls. Methods Adolescent girls (N=786, 60% African American, mean age=17.6 ± 0.6 years) performed a submaximal fitness test (PWC170). Commercial physical activity facilities were mapped and counted within a 0.75-mile street-network buffer around girls’ homes using Geographic Information Systems (GIS). Sedentary activities and vigorous physical activity (VPA, greater or equal to 6 METs) were determined by the average number of 30-minute blocks reported per day on the 3-Day Physical Activity Recall (3DPAR). Mixed model regressions were calculated using school as a random variable. Results Girls had higher weight-relative PWC170 scores if there was a commercial physical activity facility (n=186, 12.4±4.2 kg·m/min/kg) within 0.75-mile street-network buffer of home as compared to girls without a nearby facility (n=600, 11.2±3.6 kg·m/min/kg). After adjusting for demographic variables, sports participation, sedentary behaviors and VPA, having one or more commercial physical activity facilities within a 0.75-mile street-network buffer of homes was significantly related to cardiorespiratory fitness. Conclusions Both with and without adjustment for covariates, the presence of a commercial physical activity facility within a 0.75-mile street-network buffer of a girl’s home was associated with higher cardiorespiratory fitness.

  3. Reducing False Alarms of Annual Forecast in the Central China North-South Seismic Belt by Reverse Tracing of Precursors (RTP) Using the Pattern Informatics (PI) `Hotspots'

    2017-06-01

    The annual consultation on the likelihood of earthquakes in the next year, the `Annual Consultation Meeting', has been one of the most important forward forecast experiments organized by the China Earthquake Administration (CEA) since the 1970s, in which annual alarm regions are identified by an expert panel considering multi-disciplinary `anomalies'. In such annual forecasts, one of the problems in need of further technical solution is its false alarms. To tackle this problem, the concept of `reverse tracing of precursors (RTP)' is used to the annual consultation, as a temporal continuation and spatial extension of the work of Z hao et al. (Pure Appl Geophys 167:783-800, 2010). The central China north-south seismic belt (in connection to the CSEP testing region) is selected as the testing region of such an approach. Applying the concept of RTP, for an annual alarm region delineated by the Annual Consultation Meeting, the distribution of `hotspots' of the pattern informatics (PI), which targets the 5-year-scale seismic hazard, is considered. The `hit', or successful forecast, of the annual seismic hazard is shown to be related to the sufficient coverage of the `hotspots' within the annual alarm region. The ratio of the areas of the `hotspots' over the whole area of the annual alarm region is thus used to identify the false alarms which have few `hotspots'. The results of the years 2004-2012 show that using a threshold of 17 % can reduce 34 % (13 among 38) of the false alarms without losing the successful hit (being 6 in that period).

    2010-04-14

    This Annual Report presents the data and evaluates the progress of the three-component remedy implemented for remediation of groundwater contamination at Test Area North, Operable Unit 1-07B, at the Idaho National Laboratory Site. Overall, each component is achieving progress toward the goal of total plume remediation. In situ bioremediation operations in the hot spot continue to operate as planned. Progress toward the remedy objectives is being made, as evidenced by continued reduction in the amount of accessible residual source and decreases in downgradient contaminant flux, with the exception of TAN-28. The injection strategy is maintaining effective anaerobic reductive dechlorination conditions, as evidenced by complete degradation of trichloroethene and ethene production in the biologically active wells. In the medial zone, the New Pump and Treat Facility operated in standby mode. Trichloroethene concentrations in the medial zone wells are significantly lower than the historically defined concentration range of 1,000 to 20,000 μg/L. The trichloroethene concentrations in TAN-33, TAN-36, and TAN-44 continue to be below 200 μg/L. Monitoring in the distal zone wells outside and downgradient of the plume boundary demonstrate that some plume expansion has occurred, but less than the amount allowed in the Record of Decision Amendment. Additional data need to be collected for wells in the monitored natural attenuation part of the plume to confirm that the monitored natural attenuation part of the remedy is proceeding as predicted in the modeling.

    Continuing the 24 year old tradition, one of the Greek relativistic groups, this time the Relativity Group of the Physics Department of the University of Athens, organized the 12th Conference of the series "Recent Developments in Gravity" (NEB XII). This time NEB took place at Nafplio, Greece, from Thursday 29 June to Sunday 2 July, 2006. The Conference was attended by more than 100 participants, more than 50% of whom were relativists from abroad (both Greek and other nationalities). This signifies a tendency of the last few Conferences to open up the Greek Relativity Conference to the international scientific community. Actually, many notable members of the relativistic community all over the globe showed particular interest in coming to Nafplio, and spend four relaxed days in a nice sunny and historical place, presenting the results of their more recent work and discussing it with colleagues and students from Greece. The NEB XII Conference covered various aspects of gravitational physics: Relativistic Astrophysics, Mathematical Relativity, Quantum Gravity, and Cosmology. Although the program was rather heavy and for the first time we had parallel sessions running in the afternoons, the wonderful weather (apart from the last afternoon when it rained heavily) and the beauty of Nafplio helped the organizers offer the participants a warm, pleasant, and creative time. According to most attendees, their impression was more than good, not only with respect to the hospitable environment, but with respect to the high level of talks as well. We hope the next Conference, which will be organized by the Relativity Group of the Aristotle University of Thessaloniki in the summer of 2008, will raise the standards of the Conference even higher, thus further establishing our Conference as a notable Conference in the Relativistic community all over the world. Finally, we would like to thank the Gravitational Physics Section of the European Physical Society (GPS/EPS), ILIAS

    The 12th International Symposium on Multiscale, Multifunctional and Functionally Graded Materials (FGM-2012) was held in Beijing, China, from 22-36 October 2012. This was part of a series of conferences organized every two years endorsed by International Advisory Committee for FGM's, which serves as a forum for scientists, educators, engineers and young students interested in the development of functionally graded materials (FGM). The series continues from the previous international symposium on FGM held in Sendai, Japan (1990), San Francisco, USA (1992), Lausanne, Switzerland (1994), Tsukuba, Japan (1996), Dresden, Germany (1998), Estes Park, USA (2000), Beijing, China (2002), Leuven, Belgium (2004), Hawaii, USA (2006), Sendai, Japan (2008) and Guimaraes, Portugal (2010). Functionally graded materials are non-uniform materials which are designed with embodied continuous spatial variations in composition and microstructure for the specific purpose of adjusting their thermal, structural, mechanical, biological or functional response to specific application conditions. Such multi-phase materials cover a range of space and time scales, and are best understood by means of a comprehensive multiscale, multiphysics approach. These kinds of materials are presently in the forefront of materials research, receiving worldwide attention. They have a broad range of applications including for example, biomedical, biomechanical, automotive, aerospace, mechanical, civil, nuclear, and naval engineering. New applications are continuously being discovered and developed. The objective of the FGM-2012 intends to provide opportunities for exchanging ideas and discussing state-of-the-art theories, techniques and applications in the fields of multiscale, multifunctional and FGM, through invited lectures, oral and poster presentations. FGM-2012 was organized and hosted by University of Science and Technology Beijing, China, together with Tsing-hua University and Wuhan University of

    This volume of IOP Conference Series: Materials Science and Engineering contains papers from the 12th Workshop of the European Microbeam Analysis Society (EMAS) on Modern Developments and Applications in Microbeam Analysis, which took place from the 15-19 May 2011 in the Angers Congress Centre, Angers, France. The primary aim of this series of workshops is to assess the state-of-the-art and reliability of microbeam analysis techniques. The workshops also provide a forum where students and young scientists starting out on a career in microbeam analysis can meet and discuss with the established experts. The workshops have a very specific format comprising invited plenary lectures by internationally recognized experts, poster presentations by the participants and round table discussions on the key topics led by specialists in the field. This workshop was organized in collaboration with GN-MEBA - Groupement National de Microscopie Electronique à Balayage et de microAnalysis, France. The technical programme included the following topics: the limits of EPMA, new techniques, developments and concepts in microanalysis, microanalysis in the SEM, and new and less common applications of micro- and nanoanalysis. As at previous workshops there was also a special oral session for young scientists. The best presentation by a young scientist was awarded with an invitation to attend the 2012 Microscopy and Microanalysis meeting at Phoenix, Arizona. The prize went to Pierre Burdet, of the Federal Institute of Technology of Lausanne (EPFL), for his talk entitled '3D EDS microanalysis by FIB-SEM: enhancement of elemental quantification'. The continuing relevance of the EMAS workshops and the high regard in which they are held internationally can be seen from the fact that 74 posters from 18 countries were on display at the meeting, and that the participants came from as far away as Japan, Canada and the USA. A selection of participants with posters were invited to give a short oral

    2014-02-21

    The 12th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems took place in Austin, Texas (7–11 September 2011). This meeting was organized jointly with the 5th IAEA Technical Meeting on Theory of Plasma Instabilities (5–7 September 2011). The two meetings shared one day (7 September 2011) with presentations relevant to both groups. Some of the work reported at these meetings was then published in a special issue of Nuclear Fusion [Nucl. Fusion 52 (2012)]. Summaries of the Energetic Particle Conference presentations were given by Kazuo Toi and Boris Breizman. They respectively discussed the experimental and theoretical progress presented at the meeting. Highlights of this meeting include the tremendous progress that has been achieved in the development of diagnostics that enables the ‘viewing’ of internal fluctuations and allows comparison with theoretical predictions, as demonstrated, for example, in the talks of P. Lauber and M. Osakabe. The need and development of hardened diagnostics in the severe radiation environment, such as those that will exist in ITER, was discussed in the talks of V. Kiptily and V.A. Kazakhov. In theoretical studies, much of the effort is focused on nonlinear phenomena. For example, detailed comparison of theory and experiment on D-III-D on the n = 0 geodesic mode was reported in separate papers by R. Nazikian and G. Fu. A large number of theoretical papers were presented on wave chirping including a paper by B.N. Breizman, which notes that wave chirping from a single frequency may emanate continuously once marginal stability conditions have been established. Another area of wide interest was the detailed study of alpha orbits in a burning plasma, where losses can come from symmetry breaking due to finite coil number or magnetic field imperfections introduced by diagnostic or test modules. An important area of development, covered by M.A. Hole and D.A. Spong, is concerned with the self

  12. Importance of atmospherically deposited nitrogen to the annual nitrogen budget of the Neuse River estuary, North Carolina.

    Wet deposition of nitrogen, as NH(4)(+), NO(3)(-), and organic N, contributes up to 50% of the total externally supplied or 'new' N flux to the Neuse River Estuary (North Carolina). Excessive nitrogen (N) loading to N-sensitive waters such as the Neuse River Estuary has been linked to changes in microbial and algal community composition and function (harmful algal blooms), hypoxia/anoxia, and fish kills. In a 4-year study from July 1996 to July 2000, the weekly wet deposition of NH(4)(+), NO(3)(-), and dissolved organic N was calculated, based on concentration and precipitation measurements, at 11 sites on a northwest-southeast transect in the watershed. Data from this period indicate that the annual mean total wet atmospherically deposited (AD)-N flux was 11 kg ha(-1) year(-1). Deposition was fairly evenly distributed between nitrate, ammonium, and organics (32%, 32%, and 36%, respectively). Seasonally, the summer (June-August) months contained the highest weekly wet total N deposition; this trend was not driven by precipitation amount. Estimates of watershed N retention and in-stream riverine processing revealed that the AD-N flux contributed an estimated 20% (range of 15-51%) of the total 'new' N flux to the estuary, with direct deposition of N to the estuary surface accounting for 6% of the total 'new' N flux. This study did not measure the dry depositional flux, which may double the contribution of AD-N to the estuary. The AD-N is an important source of 'new' N to the Neuse River Estuary as well as other estuarine and coastal ecosystems downwind of major emission sources. As such, AD-N should be included in effective nutrient mitigation and management efforts for these N-sensitive waters.

  13. Patterns of floodplain sediment deposition along the regulated lower Roanoke River, North Carolina: annual, decadal, centennial scales

    The lower Roanoke River on the Coastal Plain of North Carolina is not embayed and maintains a floodplain that is among the largest on the mid-Atlantic Coast. This floodplain has been impacted by substantial aggradation in response to upstream colonial and post-colonial agriculture between the mid-eighteenth and mid-nineteenth centuries. Additionally, since the mid-twentieth century stream flow has been regulated by a series of high dams. We used artificial markers (clay pads), tree-ring (dendrogeomorphic) techniques, and pollen analyses to document sedimentation rates/amounts over short-, intermediate-, and long-term temporal scales, respectively. These analyses occurred along 58 transects at 378 stations throughout the lower river floodplain from near the Fall Line to the Albemarle Sound. Present sediment deposition rates ranged from 0.5 to 3.4 mm/y and 0.3 to 5.9 mm/y from clay pad and dendrogeomorphic analyses, respectively. Deposition rates systematically increased from upstream (high banks and floodplain) to downstream (low banks) reaches, except the lowest reaches. Conversely, legacy sediment deposition (A.D. 1725 to 1850) ranged from 5 to about 40 mm/y, downstream to upstream, respectively, and is apparently responsible for high banks upstream and large/wide levees along some of the middle stream reaches. Dam operations have selectively reduced levee deposition while facilitating continued backswamp deposition. A GIS-based model predicts 453,000 Mg of sediment is trapped annually on the floodplain and that little watershed-derived sediment reaches the Albemarle Sound. Nearly all sediment in transport and deposited is derived from the channel bed and banks. Legacy deposits (sources) and regulated discharges affect most aspects of present fluvial sedimentation dynamics. The lower river reflects complex relaxation conditions following both major human alterations, yet continues to provide the ecosystem service of sediment trapping.

    The lower Roanoke River on the Coastal Plain of North Carolina is not embayed and maintains a floodplain that is among the largest on the mid-Atlantic Coast. This floodplain has been impacted by substantial aggradation in response to upstream colonial and post-colonial agriculture between the mid-eighteenth and mid-nineteenth centuries. Additionally, since the mid-twentieth century stream flow has been regulated by a series of high dams. We used artificial markers (clay pads), tree-ring (dendrogeomorphic) techniques, and pollen analyses to document sedimentation rates/amounts over short-, intermediate-, and long-term temporal scales, respectively. These analyses occurred along 58 transects at 378 stations throughout the lower river floodplain from near the Fall Line to the Albemarle Sound. Present sediment deposition rates ranged from 0.5 to 3.4 mm/y and 0.3 to 5.9 mm/y from clay pad and dendrogeomorphic analyses, respectively. Deposition rates systematically increased from upstream (high banks and floodplain) to downstream (low banks) reaches, except the lowest reaches. Conversely, legacy sediment deposition (A.D. 1725 to 1850) ranged from 5 to about 40 mm/y, downstream to upstream, respectively, and is apparently responsible for high banks upstream and large/wide levees along some of the middle stream reaches. Dam operations have selectively reduced levee deposition while facilitating continued backswamp deposition. A GIS-based model predicts 453,000 Mg of sediment is trapped annually on the floodplain and that little watershed-derived sediment reaches the Albemarle Sound. Nearly all sediment in transport and deposited is derived from the channel bed and banks. Legacy deposits (sources) and regulated discharges affect most aspects of present fluvial sedimentation dynamics. The lower river reflects complex relaxation conditions following both major human alterations, yet continues to provide the ecosystem service of sediment trapping.

    The North Pacific is subject to various seasonal climate phenomena and material circulations. Therefore intra-annual ice core data are necessary for an assessment of the climate variations. To assess past variations, a 50-m ice core was drilled at the summit of Mount Wrangell Volcano, Alaska. The dust number, tritium concentrations, and stable hydrogen isotope were analyzed. The period covered was from 1992 to 2002. We found that the concentrations of both fine dust (0.52-1.00 μm), an indicator of long-range transport, and coarse dust (1.00-8.00 μm) increased together every spring. Moreover, their concentrations increased drastically after 2000, corresponding to the recent increase in Asian dust outbreaks in spring. Additionally, an increase in the spring of 2001 corresponded to the largest dust storm recorded in east Asia since 1979. Therefore our findings imply that Asian dust strongly polluted Mount Wrangell every spring. The stratospheric tracer, tritium, had late spring maxima almost every year, and we found this useful for ice core dating to identify late spring in the North Pacific region. We also found that a high positive annual correlation existed between the calculated tritium and fine dust fluxes from late spring to summer. We propose that an annual relationship between the stratosphere-troposphere exchange and Asian dust storm are most closely connected in late spring because their activities are weak in summer. The Mount Wrangell ice core is important and useful for assessing the dust and tritium circulation in the distant past around the North Pacific with probable intra-annual timescale information.

    The U.S. Geological Survey, in cooperation with the Georgia Department of Natural Resources, Environmental Protection Division, developed regional regression equations for estimating selected low-flow frequency and mean annual flow statistics for ungaged streams in north Georgia that are not substantially affected by regulation, diversions, or urbanization. Selected low-flow frequency statistics and basin characteristics for 56 streamgage locations within north Georgia and 75 miles beyond the State’s borders in Alabama, Tennessee, North Carolina, and South Carolina were combined to form the final dataset used in the regional regression analysis. Because some of the streamgages in the study recorded zero flow, the final regression equations were developed using weighted left-censored regression analysis to analyze the flow data in an unbiased manner, with weights based on the number of years of record. The set of equations includes the annual minimum 1- and 7-day average streamflow with the 10-year recurrence interval (referred to as 1Q10 and 7Q10), monthly 7Q10, and mean annual flow. The final regional regression equations are functions of drainage area, mean annual precipitation, and relief ratio for the selected low-flow frequency statistics and drainage area and mean annual precipitation for mean annual flow. The average standard error of estimate was 13.7 percent for the mean annual flow regression equation and ranged from 26.1 to 91.6 percent for the selected low-flow frequency equations.The equations, which are based on data from streams with little to no flow alterations, can be used to provide estimates of the natural flows for selected ungaged stream locations in the area of Georgia north of the Fall Line. The regression equations are not to be used to estimate flows for streams that have been altered by the effects of major dams, surface-water withdrawals, groundwater withdrawals (pumping wells), diversions, or wastewater discharges.

    Heaverlo, Carol Ann

    Researchers, policymakers, business, and industry have indicated that the United States will experience a shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this shortage, one of which includes increasing the representation of girls and women in the STEM fields. In order to increase the representation of women in the STEM fields, it is important to understand the developmental factors that impact girls' interest and confidence in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). This study identifies factors that impact girls' interest and confidence in mathematics and science, defined as girls' STEM development. Using Bronfenbrenner's (2005) bioecological model of human development, several factors were hypothesized as having an impact on girls' STEM development; specifically, the macrosystems of region of residence and race/ethnicity, and the microsystems of extracurricular STEM activities, family STEM influence, and math/science teacher influence. Hierarchical regression analysis results indicated that extracurricular STEM involvement and math teacher influence were statistically significant predictors for 6--12th grade girls' interest and confidence in mathematics. Furthermore, hierarchical regression analysis results indicated that the only significant predictor for 6--12th grade girls' interest and confidence in science was science teacher influence. This study provides new knowledge about the factors that impact girls' STEM development. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of 6--12th grade girls.

    The aim of this study was to define the role of the relative age effect in the 12th Winter European Youth Olympic Festival 2015. The birth dates of all 899 participants and anthropometric data of 655 participants were analyzed. A significant relative age effect was present in the total sample and among the male athletes but not in the female athletes. Additionally, a significant relative age effect was present in strength- and endurance-related sports but not in technique-related sports. Statistically significantly more older athletes won medals. Relative age had a strong influence on participation in strength- and endurance-related sports as well as on performance.

    This May, five seniors from the North Carolina School of Science and Mathematics and their adult leaders, Hugh Haskell and Chuck Britton, were the first US team to compete in the International Young Physicists Tournament (IYPT), which took place in Vienna, Austria. They challenged and were challenged by eighteen similar teams from sixteen other countries. The IYPT differs from the Physics Olympiad, which is an examination, whereas the Tournament is a debate on the solution of seventeen open-ended problems published in October, on the IYPT website . The five students, Adriane Boyd, Dahl Clark, Mark Blevins, Zach Keane, and Adam Simpkins spent from mid-January until our departure on May 20, preparing their responses to the questions. In Vienna, the team was joined by Ron Edge, of the University of South Carolina, who served as jurist for the tournament. Each team pays for transportation, but once there, the host country bears all other costs. For each event, called a "physics fight," three teams are assigned their roles-reporter, opponent and reviewer. First, the opposing team selects a question. The reporters have twelve minutes to present a report. The opposing team then has five minutes to critique the report. After a rebuttal by the reporter, the reviewers discuss effectiveness of both presentations . Finally, the jurors ask questions and score each team. This year's overall winner was Germany. Taking second was the team from the Republic of Georgia. The US team did not make the semifinal round, but did well enough for a first-time competitor. Will there be another United States Team? This is an open question. Efforts are being made to find a school that can send a team to next year's competition which is scheduled for Budapest, Hungary.

    Molecular typing for HLA class I was introduced in the 12th International Histocompatibility Workshop. Following a pilot study using three methods, sequence specific oligotyping (SSO), reverse dot blot and amplification refractory mutation system (ARMS)-PCR, the ARMS-PCR method was selected for use. A great advantage of an ARMS-PCR method is that, unlike the other two methods, it can determine whether sequence motifs are in cis or in trans, as ARMS-PCR detects two cis located motifs per reaction using forward and reverse sequence specific primers. Resolution was designed to be low to medium level for HLA-A, -B and -C alleles. Two hundred and fifty class I kits and 83 HLA-A2 subtyping kits were distributed. The A2 subtyping kit used a two round nested PCR system to identify all of the A2 alleles known at the time. Typing results on control DNA samples distributed with both the kits showed a very satisfactory performance. Since the 12th Workshop, the kits have been developed with the addition of new primers and primer mixes to increase the resolution of the test.

    Technology has improved many educational issues. This is a very exciting time for technology and education. The primary purpose of this study was aimed at understanding the impact of home computer use on academic achievement in the computer curriculum of the 12th grade students in Riyadh, Kingdom of Saudi Arabia. In particular, the study attempted to determine if the use of home computers would be an effective manner for increasing students' academic achievement. The participants of the study were 240 male and female students as a random sample from 12th grade from eight random high schools in Riyadh, Saudi Arabia. An achievement exam and survey were developed by the researcher based on the computer science curriculum topics, the quantitative data was collected in both a single achievement exam and a single survey from a sample of 240 Saudi high school students. Both the survey and an achievement exam were split equally between male and female students. The study sought the answer to 10 questions. Analysis of variance (ANOVA), followed by tests of simple main effects and post hoc comparisons using Scheffe, as well as Pearson Correlation were conducted to answer the research questions. The study results pointed out that home computers were important to support the students in their academic achievement in the computer science curriculum. Therefore, more attention must be given to the use of home computers for all students. Moreover, we should attempt to treat the difficulties which students face for getting computers in their homes.

  3. Net air-sea surface heat flux during 1984-2004 over the North Pacific and North Atlantic oceans (10°N-50°N): annual mean climatology and trend

    Using the Objectively Analyzed air-sea Fluxes dataset (and also the National Oceanography Centre Southampton Flux Dataset v2.0), we examined both the annual mean climatology and trend of net air-sea surface heat flux ( Q net) for 1984-2004 over the North Pacific and North Atlantic oceans (10°N-50°N). The annual mean Q net climatology shows that oceans obtain the positive Q net over much of the North Pacific and North Atlantic oceans. Exceptions are the regions of western boundary currents (WBCs) including the Kuroshio and its extension off Japan and the Gulf Stream off the USA and its extension, where oceans release lots of heat into the atmosphere, mainly ascribed to the large surface turbulent heat loss. The statistically significant negative Q net trends occurred in the WBCs, while the statistically significant positive Q net trends appeared in the central basins of Northern Subtropical Oceans (CNSOs) including the central basin of Northern Subtropical Pacific and the central basin of Northern Subtropical Atlantic. These indentified Q net trends, which are independent of both El Niño-Southern Oscillation (ENSO) and ENSO Modoki but closely related to global warming forcing, are predominately due to the statistically significant surface latent heat (LH) trends. Over the WBCs, the positive LH trends are mainly induced by the sea surface temperature increasing, indicating the ocean forcing upon overlying atmosphere. In contrast, over the CNSOs, the negative LH trends are mainly caused by the near-surface air specific humidity increasing, indicative of an oceanic response to overlying atmospheric forcing.

    The lack of annually-resolved marine climate records spanning the last millennium constrains our understanding of the natural variability of the global climate system. We present a continuous annually-resolved reconstruction of sub-polar (N Iceland) sea water temperatures (SWT) derived from the 18O analyses of carbonate material drilled from the annually resolved growth increments contained in an absolutely dated master Arctica islandica sclerochronology spanning the period 953-2000. The calibrated SWT reconstruction contains a significant cooling trend over the period 953-1891 (0.1oC per century) and a marked warming trend over the period 1891-2000 (2.3oC per century). The underlying natural variability is controlled by solar irradiance changes modulated by volcanic forcing and internal variability. The modern SWT warming is demonstrated to lie outside the range of natural variability of the last 1000 years consistent with an anthropogenic influence.

    Arctic and sub-arctic watersheds are undergoing significant changes due to recent climate warming and degrading permafrost, engendering enhanced monitoring of arctic rivers. Smaller catchments provide understanding of discharge, solute flux and groundwater recharge at the process level that contributes to an understanding of how larger arctic watersheds are responding to climate change. The North Klondike River, located in west central Yukon, is a sub-alpine permafrost catchment, which maintains an active hydrological monitoring station with a record of >40 years. In addition to being able to monitor intra-annual variability, this data set allows for more complex analysis of streamflow records. Streamflow data, geochemistry and stable isotope data for 2014 show a groundwater-dominated system, predominantly recharged during periods of snowmelt. Radiocarbon is shown to be a valuable tracer of soil zone recharge processes and carbon sources. Winter groundwater baseflow contributes 20 % of total annual discharge, and accounts for up to 50 % of total river discharge during the spring and summer months. Although total stream discharge remains unchanged, mean annual groundwater baseflow has increased over the 40-year monitoring period. Wavelet analysis reveals a catchment that responds to El Niño and longer solar cycles, as well as climatic shifts such as the Pacific Decadal Oscillation.

    The central route of China's South to North Water Diversion Project is planned to divert water from the Danjiangkou Reservoir to Beijing. Currently, the main local surface water source for Beijing is the Miyun Reservoir. Annual runoffs in both of the Danjiangkou Reservoir Basin and Miyun Reservoir Basin decreased significantly from 1956 to 2009. For the Danjiangkou Reservoir Basin, average annual runoff was 428.5 mm from 1956 to 1989, while it decreased to 328.2 mm from 1990 to 2009. For the Miyun Reservoir Basin, the average annual runoff was 101.8 mm from 1956 to 1979 and decreased to 40.8 mm from 1980 to 2009. We investigate that climatic fluctuation was the main reason of the decreasing runoff in the Danjiangkou Reservoir Basin, while human influences were the main reason of the decreasing runoff in the Miyun Reservoir Basin. We speculate that the declining runoff in a water source and a destination for that source would increase the probability of a simultaneous dry year for the two regions. The increasing probability of a simultaneous dry year indicates an increasing frequency of years in which Beijing urgently needs diversion water while the Danjiangkou Reservoir will not be able to meet the demands. This situation could threaten the success of the entire water diversion project and the sustainable development of Beijing. We suggest that the water diversion from the Danjiangkou Reservoir should be conducted in an adaptive manner to avoid such an adverse consequence.

    Objective To examine the relationship between perceived family support and other selected correlates of physical activity (PA) with changes in PA over time. Methods A total of 421 girls in South Carolina completed questionnaires at 8th, 9th and 12th grades (1998–2003). Family support for PA, PA self-efficacy, perceived behavioral control, attitudes, availability of equipment, and PA were measured. Results Growth curve analysis showed that family support, perceived behavioral control, and self-efficacy were independently related to age-related changes in PA as reflected by total METs. Girls who reported lower family support at the 8th grade measure had more rapid declines in PA, and a unit change in family support was related to approximately 1/3 of a standard deviation change in total METs. Conclusions Maintenance of support from family members may reduce the decline in PA independent of girl’s self-efficacy and perceived behavioral control. PMID:17157371

    A 6-year-old, female spayed Pomeranian was presented with acute hind-limb paraplegia with the presence of deep pain perception and urinary incontinence. Myelography showed a Hansen type I herniation of the12th to 13th thoracic intervertebral space (T(12-13)). Articular facets of the T(12-13) and T(13) to first lumbar vertebra (L(1)) were absent. The spinal cord was decompressed using a bilateral T(12-13) modified lateral hemilaminectomy (pediculectomy). The aplastic sites were associated with minimal instability of the vertebral column, and stabilization of the vertebral column was not required. Familiarity with this condition is important, because articular facet aplasia may cause vertebral instability and may require an adjusted surgical approach or vertebral reduction and fusion following decompression.

    The 12th meeting of the Scientific Group on Methodologies for the Safety Evaluation of Chemicals (SGOMSEC) considered the topic of methodologies for determining human and ecosystem susceptibility to environmental hazards. The report prepared at the meeting describes measurement of susceptibility through the use of biological markers of exposure, biological markers of effect, and biomarkers directly indicative of susceptibility of humans or of ecosystems. The utility and validity of these biological markers for the study of susceptibility are evaluated, as are opportunities for developing newer approaches for the study of humans or of ecosystems. For the first time a SGOMSEC workshop also formally considered the issue of ethics in relation to methodology, an issue of particular concern for studies of susceptibility. PMID:9255554

  10. The effect of trade books on the environmental literacy of 11th and 12th graders in aquatic science

    Lewis, Ann S.

    The purpose of this study was to compare the environmental literacy of 11th and 12th graders who participated in an eighteen-week environmental education program using trade books versus 11 th- and 12th-graders who participated in an eighteen-week, traditional environmental education program without the use of trade books. This study was conducted using a quasi-experimental research technique. Four high school aquatic science classes at two suburban high schools were used in the research. One teacher at each high school taught one control class and one experimental class of aquatic science. In the experimental classes, four trade books were read to the classes during the eighteen-week semester. These four books were selected by the participating teachers before the semester began. The books used were A Home by the Sea, Sea Otter Rescue, There's a Hair in My Dirt, and The Missing Gator of Gumbo Limbo. The instrument used to measure environmental literacy was the Children's Environmental Attitude and Knowledge Scale. This test was given at the beginning of the semester and at the end of the semester. The scores at the end of the semester were analyzed by 2 x 2 mixed model ANOVA with the teacher as the random effect and the condition (trade books) as the fixed effect. The statistical analysis of this study showed that the students in the experimental classes did not score higher than the control classes on the Children's Environmental Attitude and Knowledge Scale or on a subset of "water" questions. Several limitations were placed on this research. These limitations included the following: (1) a small number of classes and a small number of teachers, (2) change from the original plan of using environmental science classes to aquatic science classes, (3) possible indifference of the students, and (4) restrictive teaching strategies of the teachers.

    Root canal preparation may damage NiTi instruments resulting in wear and deformation. The aim of this study was to make a comparative evaluation of the surface topography of the cervical third of four different rotary systems, before and after being used twelve times, in 1.440 resin blocks with simulated root canals with standardized 45° curvatures, and analyzed by atomic force microscopy AFM. The blocks were divided into four groups and prepared according to the manufacturers recommendations: Group 1--K3®; Group 2--Protaper Universal®; Group 3--Twisted Files® and Group 4--Biorace®. After each preparation, the instruments were washed and autoclaved. A total of 240 instruments were selected, being 30 new instruments and 30 after having been used for the 12th time, from each group. These instruments were analyzed by AFM and for quantitative evaluation, the mean RMS (Root mean square) values of the cervical third of the specimens from the four groups were used. The result showed that all the rotary files used for the 12th time suffered wear with change in the topography of the cervical region of the active portion of the file (ANOVA p < 0.01). Classifying the specimens in increasing order, from the least to the greatest wear suffered, Group 3 (2.8993 nm) presented the least wear, followed by Group 4 (12.2520 nm), Group 1 (36.0043 nm) and lastly, Group 2 (59.8750 nm) with the largest amount of cervical surface wear.

    Biomass accumulation and allocation patterns are critical to quantifying ecosystem dynamics. However, these patterns differ among species, and they can change in response to nutrient availability even among genetically related individuals. In order to understand this complexity further, this study examined three ephemeral species (with very short vegetative growth periods) and three annual species (with significantly longer vegetative growth periods) in the Gurbantunggut Desert, north-western China, to determine their responses to different nitrogen (N) supplements under natural conditions. Nitrogen was added to the soil at rates of 0, 0.5, 1.0, 3.0, 6.0 and 24.0 g N m(-2) year(-1). Plants were sampled at various intervals to measure relative growth rate and shoot and root dry mass. Compared with annuals, ephemerals grew more rapidly, increased shoot and root biomass with increasing N application rates and significantly decreased root/shoot ratios. Nevertheless, changes in the biomass allocation of some species (i.e. Erodium oxyrrhynchum) in response to the N treatment were largely a consequence of changes in overall plant size, which was inconsistent with an optimal partitioning model. An isometric log shoot vs. log root scaling relationship for the final biomass harvest was observed for each species and all annuals, while pooled data of three ephemerals showed an allometric scaling relationship. These results indicate that ephemerals and annuals differ observably in their biomass allocation patterns in response to soil N supplements, although an isometric log shoot vs. log root scaling relationship was maintained across all species. These findings highlight that different life history strategies behave differently in response to N application even when interspecific scaling relationships remain nearly isometric.

    Simulated inter-annual to decadal variability and trends in the North Atlantic for the1958-2007 period from twenty global ocean - sea-ice coupled models are presented.These simulations are performed as contributions to the second phase of the CoordinatedOcean-ice Reference Experiments (CORE-II). A major focus of the present study is the representation of Atlanticmeridional overturning circulation (AMOC) variability in the participating models.Relationships between AMOC variability and those of some other related variables, suchas subpolar mixed layer depths, the North Atlantic Oscillation (NAO), and the LabradorSea upper-ocean hydrographic properties, are also investigated. In general, AMOCvariability shows three distinct stages. During the first stage that lasts until the mid-to late-1970s, AMOC is relatively steady, remaining lower than its long-term(1958-2007) mean. Thereafter, AMOC intensifies with maximum transports achieved in the mid- to late-1990s. This enhancement isthen followed by a weakening trend until the end of our integration period. Thissequence of low frequency AMOC variability is consistent with previous studies.Regarding strengthening of AMOC between about the mid-1970s and the mid-1990s, our resultssupport a previously identified variability mechanism where AMOC intensification isconnected to increased deep water formation in the subpolar North Atlantic, drivenby NAO-related surface fluxes. The simulations tend to show general agreement in theirrepresentations of, for example, AMOC, sea surface temperature (SST), and subpolar mixed layerdepth variabilities. In particular, the observed variability of the North Atlantic SSTs iscaptured well by all models. These findings indicate that simulated variability andtrends are primarily dictated by the atmospheric datasets which include the influenceof ocean dynamics from nature superimposed onto anthropogenic effects. Despite thesegeneral agreements, there are many differences among the model solutions

    This summary of the NAPRTCS 2006 Annual Report of the Transplant Registry highlights the significant impact the registry has had in advancing knowledge in pediatric renal transplantation worldwide. This cooperative group has collected clinical information on children undergoing a renal transplantation since 1987 and now includes over 150 participating medical centers in the USA, Canada, Mexico, and Costa Rica. Currently, the NAPRTCS transplant registry includes information on 9837 renal transplants in 8990 patients (NAPRTCS 2006 Annual Report). Since the first data analysis in 1989, NAPRTCS reports have documented marked improvements in outcome after renal transplantation in addition to identifying factors associated with both favorable and poor outcomes. The registry has served to document and influence practice patterns, clinical outcomes, and changing trends in renal transplantation.

    Long instrumental records of meteorological variables such as temperature and precipitation are very useful for studying regional climate in the past, present, and future. They can also be useful for understanding the influence of large-scale atmospheric circulation processes on the regional climate. This paper investigates the monthly, winter, and annual temperature time series obtained from the instrumental records in Zagreb, Croatia, for the period 1864-2010. Using wavelet analysis, the dominant modes of variability in these temperature series are identified, and the time intervals over which these modes may persist are delineated. The results reveal that all three temperature records exhibit low-frequency variability with a dominant periodicity at around 7.7 years. The 7.7-year cycle has also been observed in the temperature data recorded at several other stations in Europe, especially in Northern and Western Europe, and may be linked to the North Atlantic Oscillation (NAO) and/or solar/geomagnetic activity.

    Hurricanes are large-scale atmospheric phenomena that typically produce high volume, high intensity, and isotopically depleted rainfall. Such storms have the ability to alter the isotopic composition of the groundwater reservoir, imparting a uniquely negative isotopic fingerprint to actively growing stalagmites. In regions influenced by the Intertropical Convergence Zone (ITCZ), large volumes of rainfall delivered during the wet season can obscure the tropical cyclone (TC) rainfall proxy signal. Coupled annually resolved carbon and oxygen isotope ratios were used to isolate the low δ18O TC signal from the isotopically more enriched background rainfall associated with seasonal ITCZ migration. The new composite stalagmite proxy record yielded a 99.7% significant correlation with the western Caribbean-filtered HURDAT2 database over the instrumental record based on a non-parametric bootstrap approach. The new annually-resolved TC reconstruction for the western Caribbean spans the last 450 years and reveals a peak in western Caribbean TCs at 1650 C.E. and a gradual decline until a marked decrease is observed at the start of the Industrial Era. Comparison with documentary records of TC occurrence along the US eastern seaboard reveals a clear pattern of north-eastward TC track migration since peak Little Ice Age cooling. This pattern is consistent with natural warming since the Little Ice Age temperature minimum and with anthropogenic influences after industrialisation. Satellite observations reveal Hadley cell expansion has occurred over the last three decades and modelling studies implicate rising atmospheric greenhouse gas concentrations as the driver. Our results suggest that Hadley cell position and width is a major control on hurricane track position and that future emissions scenarios (continued rising greenhouse gases coupled with decreasing Northern Hemisphere aerosol emissions) are likely to increase storm risk to the north-eastern USA.

  6. Historical changes in the annual number of large floods in near-natural catchments across North America and Europe, 1931-2010

    Previous investigations have analyzed historical changes in low magnitude floods, such as the annual peak flow, at regional or national scales. These investigations often use catchments where streamflows have been influenced by human alterations such as reservoir regulation or urbanization. No known studies have analyzed changes in large floods (greater than 25-year return period floods) at a continental scale for near-natural catchments. To fill this research gap, this study analyzed flood flows from reference hydrologic networks (RHNs) or RHN-like gauges in North America (United States and Canada) and Europe (United Kingdom, Ireland, France, Spain, Germany, Switzerland, Iceland, Norway, Denmark, Sweden, and Finland). RHNs are formally defined networks in several countries that comprise gauges with a natural or near-natural flow regime and that provide good quality data. Selected RHN-like gauges were included following a major effort to ensure RHN-like status through consultation with local experts. Some 1206 study gauges met near-natural and completeness criteria for 1961-2010 and 322 gauges met criteria for 1931-2010. Peak flows with recurrence intervals of 25, 50, and 100 years were estimated using the generalized extreme-value distribution and L-moments, and peak flows at each gauge that exceeded these flood thresholds in each year were compiled. Continental and regional trends over time in the annual number of large floods, including groups differentiated by catchment size and major Köppen-Geiger climate group, are being computed and will be presented at EGU. Plots will also show the decadal variability in the annual number of large floods. The unique dataset used for this study is an example of successful international collaboration on hydro-climatic data exchange, which is potentially a step towards establishing RHN or RHN-like networks and analyzing near-natural streamflows on a global scale.

    A selection of illuminations of the 12th century manuscript Liber Floridus was analysed with Raman spectroscopy (in situ and laboratory measurements), X-ray fluorescence spectroscopy, UV-fluorescence photography and infrared reflectography (IRR). The aim of this study is to determine the pigments used, in order to search for anachronisms. Using a combination of Raman spectroscopy (molecular information) and X-ray fluorescence spectroscopy (elemental information) following pigments could be identified: ultramarine (Na 8-10Al 6Si 6O 24S 2-4), azurite (2CuCO 3·Cu(OH) 2), caput mortuum (Fe 2O 3), vermilion (HgS), orpiment (As 2S 3) and lead white (2PbCO 3·Pb(OH) 2). Moreover, two synthetic red pigments, PR4 and PR176, and a degradation product, gypsum (CaSO 4·2H 2O), were present in the manuscript. To establish the origin of the modern materials UV-fluorescence photography was used. Infrared reflectography (IRR) was applied to visualise the underdrawing of the investigated folios.

    The 12th World Congress of Sexology took place in August 1995 in Japan under the sponsorship of the World Association for Sexology, a conglomerate of 60 member organizations representing 25 countries. The conference focused on sexuality education, and participants from around the world recounted how sexuality education and sexual rights are being politicalized in their countries. Sexuality professionals world-wide look to US professionals for information about effective programs, resources, and research, but the US has a great deal to learn from countries such as those in Scandinavia which have extremely low levels of unplanned pregnancy or sexually transmitted diseases as a result of their commitment to sexuality education and services for young people. During the Congress, debates centered around whether the nature of sexuality is a social construct or is innate and universal. The biological nature of sexuality was explored, and reports of sexuality surveys from around the world revealed surprisingly similar patterns of behavior. Homosexuality emerged as the issue most shaped by culture. In some countries, male same-sex behavior is recognized without being categorized into a separate identity. Terminology for sex behavior also differs across cultures. For example, there is no word for "abstinence" in Japanese or in Swedish. Conference participants were urged to exchange information, expand their work in sex education to "sexuality" education, evaluate their efforts, educate themselves and others, and encourage reforms to assure sexuality education and sexual rights.

    Volcanic processes occur in a wide range of temporal and spatial scales. However, a key step of magma ascent is recognizable in the dynamics of gas and magma in the shallow plumbing system, where volatiles play a fundamental role in controlling the eruptive style. With the aim of investigating shallow degassing processes, an experimental setup was deployed at Mt. Yasur, an active volcano located in Tanna Island (Vanuatu arc), from 9th to 12th July 2011. The setup comprised high-speed and thermal cameras, as well as a microphone, capable of recording both in the infrasonic and audible range. The analysis of acoustic signals, validated by observing images from the high-speed and thermal cameras, has enabled characterizing the explosive activity during the investigated period. Two types of explosions, distinct for spectral features and waveforms, were observed: (i) minor events, corresponding to small overpressurized bursts, occurring almost continuously; (ii) major events, characterizing the Strombolian activity at Mt. Yasur. By investigating variation in the occurrence rate of the minor events, we found that, on a short timescale, the dynamics responsible for the two types of explosions are decoupled. These results, together with previous literature data, bring additional evidence of the existence of distinct sources of degassing. Finally, major events can be distinguished as emergent events, i.e. long-lasting signals, corresponding to ash-rich explosions, and impulsive events, featuring shorter duration and larger amplitude.

    Available European data indicate that during the past 2500 years there have been periods of rapid intensity geomagnetic fluctuations (at least of ~20 μT/century) interspersed with periods of little change. The challenge now is to precisely describe these rapid changes by the acquisition of well-dated high-quality archeomagnetic data. In this study we report the archeomagnetic study of Spanish ceramic fragments. The collected fragments belong to 14 superposed stratigraphic levels corresponding to a surface no bigger than 3 m by 7 m. The pottery fragments dates back to the 9th and 11th centuries. The dating was established by 4 radiocarbon dates and by archeological/historical constraints including typological comparisons and well-controlled stratigraphic constrains between the different stratigraphic units. From classical Thellier experiments including TRM anisotropy and cooling rate corrections upon archeointensity estimates and conducted on 79 fragments, twelve new high-quality mean intensities have been obtained. Together with previously published high-quality data from Western Europe, the new data provide an improved description of the intensity changes that took place in Spain between the 9th and the 12th centuries. The results confirm that rapid intensity changes took place in Western Europe during the recent history of the Earth.

  14. An annually resolved marine proxy record for the 8.2K cold event from the northern North Sea based on bivalve shells

    NASA Astrophysics Data System (ADS)

    2017-04-01

    The so-called 8.2K cold event is a rapid cooling of about 6° +/- 2° recorded in the Greenland ice core record and thought to be a consequence of a freshwater pulse from the Laurentide ice sheet which reduced deepwater formation in the North Atlantic. In the Greenland ice cores the event is characterized by a maximum extent of 159 years and a central event lasting for 70 years. As discussed by Thomas et al (QSR, 2007), the low resolution and dating uncertainty of much palaeoclimate data makes it difficult to determine the rates of change and causal sequence that characterise the event at different locations. We present here a bivalve shell chronology based on four shells of Arctica islandica from the northern North Sea which (within radiocarbon uncertainty) is coeval with the 8.2K event recorded in the Greenland ice cores. The years of death of each shell based on radiocarbon analysis and crossmatching are 8094, 8134, 8147, and 8208 yrs BP (where "present" = AD 1950), with an associated radiocarbon uncertainty of +/-80 yrs, and their longevities are 106, 122, 112 and 79 years respectively. The total length of the chronology is 192 years (8286 - 8094 BP +/- 80 yrs). The most noticeable feature of the chronology is an 60-year period of increasing growth which may correspond to a similar period of decreasing ice accumulation in the GRIP (central Greenland) ice core record. We tentatively suggest that this reflects increasing food supply to the benthos as summer stratification is weakened by colder seawater temperatures. Stable isotope analyses (results expected to be available when this abstract is presented), will show changes at annual and seasonal resolution, potentially giving a very detailed insight into the causal factors associated with the 8.2K event and its impact in the northern North Sea.

  15. An annually-resolved palaeoenvironmental archive for the Eastern Boundary North Atlantic upwelling system: Sclerochronology of Glycymeris glycymeris (Bivalvia) shells from the Iberian shelf

    The seasonally variable western Iberia upwelling system, albeit placed at a crucial climatic boundary position to record high frequency climate events, lacks well-dated high-resolution records of environmental variability. Bivalve shells provide robust high-resolution archives of oceanographic and climatic variability on timescales of decades to millennia. In particular, the North Atlantic Ocean region has recently seen several noteworthy sclerochronological and geochemical reconstructions based on bivalve shells (mainly Arctica islandica) of high frequency oceanographic and climatic conditions during the last millennium. However, due to the absence of Arctica islandica and similarly long-lived bivalves, sclerochronological palaeoenvironmental studies of southern European coastal shelf seas are scarce. In particular, none of these studies focus on reconstructing the variability of an eastern boundary upwelling system. The relatively long-lived bivalve (>100 years) Glycymeris glycymeris occurs in European and North West African coastal shelf seas and provides a valid annually resolved archive of environmental conditions during growth. Annual growth increment width series from living G. glycymeris shells, collected in 2014 on the western Iberian continental shelf (ca. 35 m water depth), were used to construct a statistically robust, ca. 70-year long absolutely-dated chronology. Sub-annually resolved (11 to 22 samples per year) oxygen stable isotope (δ18Oshell) data covering three years of shell growth, together with the direct evaluation of the time of growth mark deposition in shells collected during the autumn and winter months, were used to constrain the season of growth and to evaluate the seasonal bias of the sea-surface temperature signal preserved in the δ18Oshelldata. The growth increment width and δ18Oshell series, once robustly calibrated against modelled and instrumental oceanographic and climatic series, potentially provide novel insights into the

    Straw return in combination with synthetic N fertilizer is considered to be beneficial to soil fertility and crop yield. Such practice, however, can considerably modify soil microbial activity and relative C and N availability, both of which are known to regulate soil nitrous oxide (N2O) and nitric oxide (NO) emissions. Minimizing these emissions per unit of crop yield is a prerequisite to minimize the environmental footprint of agricultural production and thus, a policy objective. In our study, we quantified N2O and NO emissions and determined fertilizer-N use efficiencies (NUE) and crop yields of two double-cropping (summer maize/Welsh onion-winter wheat) systems with and without straw incorporation in the North China Plain. Relative to the fertilized treatment without straw amendments, straw incorporation showed a significant inhibitory effect on annual N2O emissions from the maize-wheat system (-31%), but no significant effect was observed for the Welsh onion-wheat system. However, straw return significantly reduced annual NO emissions by >30% for both systems. Meanwhile, straw return in both systems significantly increased the NUE and crop yields by 34-47% and 7-16%, respectively, as compared to the treatment without straw additions. Across the double-cropping systems, annual direct emission factors of N2O, NO and N2O+NO were 0.37-0.57%, 0.08-0.78% and 0.57-1.36%, respectively. Furthermore, a negative relationship between direct emission factors of N2O+NO and crop NUE was observed, highlighting the importance of optimizing NUE for reducing environmental risks of a cropping system. When expressing emissions on a yield basis, straw return significantly reduced annual yield-scaled N2O+NO emissions by 15-42% for both systems. Overall, our results show that the combined application of crop straw and synthetic N fertilizer is a promising N management strategy for maximizing crop yields while mitigating N-trace gas emissions.

  11. Social Media and Scientific Meetings: Education Exhibit "Likes" at the Radiological Society of North America Annual Meeting.

    PubMed

    Bunch, Paul M; Wortman, Jeremy R; Andriole, Katherine P

    2016-03-01

    Viewers of electronic education exhibits at the 2013 and 2014 Radiological Society of North America meetings had the opportunity to "like" exhibits, as one might "like" a Facebook or an Instagram post. The purposes of this study were (1) to evaluate for a relationship between exhibit popularity and receiving an award or RadioGraphics invitation, (2) to evaluate for a relationship between exhibit recognition and subsequent popularity, and (3) to quantify and compare the electronic education exhibit likes at the 2013 and the 2014 meetings. Exhibit likes were recorded at the midpoints and ends of both meetings. Data analyses were performed by means of one-way analysis of variance and chi-square tests. There were similar numbers of electronic education exhibits at the 2013 (1856) and 2014 (1793) meetings with no significant difference between meeting years in the number of exhibits chosen for awards (423 vs. 404, P = 0.88) or for RadioGraphics solicitation (190 vs. 169, P = 0.46). In both meeting years, there were statistically significant associations between initial and overall exhibit popularity and exhibit recognition, as well as between exhibit recognition and subsequent popularity. A 152% increase in total likes recorded was observed at the 2014 meeting as compared to the 2013 meeting (11074 vs. 4391, P < 0.0001). Popular exhibits were significantly more likely to receive awards and RadioGraphics invitations. Receiving an award or RadioGraphics invitation was associated with subsequent increased exhibit popularity. Significantly more likes were recorded at the 2014 Radiological Society of North America meeting than at the 2013 meeting. Copyright © 2015 The Association of University Radiologists.

    It was a great pleasure and an honor for us to host the 12th Gravitational Wave Data Analysis Workshop (GWDAW) at MIT and the LIGO Laboratory in Cambridge, Massachusetts, the place where this workshop series started in 1996. This time the conference was held at the conference facilities of the Royal Sonesta Hotel in Cambridge from 13 16 December, 2007. This 12th GWDAW found us with the ground interferometers having just completed their most sensitive search for gravitational waves and as they were starting their preparation to bring online and/or propose more sensitive instruments. Resonant mass detectors continued to observe the gravitational wave sky with instruments that have been operating now for many years. LISA, the Laser Interferometer Space Antenna, was recently reviewed by NASA's Beyond Einstein Program Assessment Committee (BEPAC) convened by the National Research Council (NRC) and found that 'on purely scientific grounds LISA is the mission that is the most promising and least scientifically risky…thus, the committee gave LISA its highest scientific ranking'. Even so, JDEM, the Joint Dark Energy Mission, was identified to go first, with LISA following a few years after. New methods, analysis ideas, results from the analysis of data collected by the instruments, as well as Mock Data Challenges for LISA were reported in this conference. While data from the most recent runs of the instruments are still being analyzed, the first upper limit results show how even non-detection statements can be interesting astrophysics. Beyond these traditional aspects of GWDAW though, for the first time in this workshop we tried to bring the non-gravitational wave physics and astronomy community on board in order to present, discuss and propose ways to work together as we pursue the first detection of gravitational waves and as we hope to transition to gravitational wave astronomy in the near future.

    The 12th International Conference on Vibrations at Surfaces (VAS 12) took place from 20 26 July 2007 as an event of the International School of Solid State Physics at the Ettore Majorana Foundation and Centre for Scientific Culture, Erice (Italy). The format and special environment of the conference have contributed to its transition from a traditional, medium-size conference into a more effective workshop, with a series of lectures reporting the most recent developments in the field, two poster sessions presenting recent results and even works in progress being discussed. The papers collected in this issue cover the highlights of the conference very thoroughly. Quite a few novel aspects concerning vibrations at surfaces are represented here, for example: new aspects in surface phonon spectroscopy, such as the very recent progress in inelastic x-ray scattering, the first observation of the boson peak in disordered surfaces, progress in the theory of atom scattering inelastic resonances, the action spectroscopy, the study of polycrystalline surfaces with electron energy-loss spectroscopy etc; parallel developments in experimental vibrational studies of adsorbed phases, either inorganic or organic, with those in ab initio theoretical simulations; the theory of enhanced electron--phonon interaction in low dimensions (2D and 1D); the extension from the traditional realm of surface vibrations and spectroscopy to other aspects of surface dynamics, like friction and various nonlinear effects, and to relevant dynamical phenomena occurring at interfaces. Other novelties presented at the conference, but already published in recent issues of the Journal of Physics: Condensed Matter, are also worth mentioning: the spin-echo spectroscopy with 3He allowing for slow-dynamics spectroscopy at very high, unprecedented resolutions (2007 J. Phys.: Cond. Matter 19 300301 and 305010; the first demonstration of dissociative surface trapping of molecules (2007 J. Phys.: Cond. Matter 19

    1996-07-29

    The records of all women applying for permission to have an abortion performed after the 12th week of pregnancy during a one-year period in the County of Aarhus were continuously reviewed, and the women who had the abortion performed due to psychosocial reasons were interviewed with a questionnaire at the time of the abortion and again four months later. Of the 76 women who applied for permission for a late abortion the following were excluded from the study: 31 who had the abortion because a malformed child was suspected, six women who did not have the abortion although permission had been given, five women who did not receive permission, four who were under 18 years of age, one who had a miscarriage, 10 who were from another country of origin and did not understand Danish and finally four women who were allowed an abortion on a medical indication and who were either in hospital or in jail. Fifteen women were questioned concerning their age, length of pregnancy and psychological and social histories and were asked to fill out a depression scale. The data showed that none of them had planned their pregnancy and they had had no symptoms of pregnancy until the time at which they applied for the abortion. None of them regretted the abortion afterwards; half of the women were under psychological strain at the time of application, and a few of them had even more psychological symptoms four months after the abortion. Although they had many social problems, physical complications and psychological problems only a few of the women had seen a doctor in the four month period between the abortion and the follow-up.

  5. [The 12th amendment to the German Drug Law. Chances and obstacles for investigator-initiated clinical trials].

    PubMed

    2005-04-01

    The European Union's so called Clinical Trials Directive 2001/20/EC was implemented in national law in Germany in August 2004, leading to the 12th amendment of the German Drug Law (Arzneimittelgesetz). The directive is intended to harmonize the clinical trial's regulatory environment across the European Union and to improve protection of human subjects. It lays down the principles and guidelines of Good Clinical Practice (GCP). As the regulation applies to all clinical trials on medicinal products for human use, and as only non-interventional studies are excluded, academic, investigator-initiated clinical trials will also have to comply with the EU clinical trials directive implemented in the German Drug Law. In an investigator-initiated trial in which the investigator takes the responsibility of a sponsor, the investigator-sponsor must take total legal and financial responsibility for the clinical trial. Since publicly funded clinical trials make a large contribution to improved care, concern has been expressed that non-commercial research projects will be reduced and the vital medical research conducted at academic institutions curtailed. Nonetheless GCP ensures a valid study design, qualified data management, analysis and monitoring of the trial and thereby promotes more valid data and protection of study participants. The trials are more likely to lead to reliable results leading to new therapies, strategies or a better understanding of diseases. What is needed, therefore, is an increase in public funding and the establishment of clinical trial units/organizations associated with the universities or hospitals where independent researchers have the possibility to obtain theoretical advice and practical help, professional training and support. In the end, the directive may serve as a stimulus to build a better national research environment and to promote public funding, and may lead to fewer but more valid clinical trials.

  6. Trends in weight management goals and behaviors among 9th-12th grade students: United States, 1999-2009.

    To examine trends in weight management goals and behaviors among U.S. high school students during 1999-2009. Data from six biennial cycles (1999-2009) of the national Youth Risk Behavior Survey were analyzed. Cross-sectional, nationally representative samples of 9th-12th grade students (approximately 14,000 students/cycle) completed self-administered questionnaires. Logistic regression models adjusted for grade, race/ethnicity, and obesity were used to test for trends in weight management goals and behaviors among subgroups of students. Combined prevalences and trends differed by sex and by race/ethnicity and weight status within sex. During 1999-2009, the prevalence of female students trying to gain weight decreased (7.6-5.7 %). Among female students trying to lose or stay the same weight, prevalences decreased for eating less (69.6-63.2 %); fasting (23.3-17.6 %); using diet pills/powders/liquids (13.7-7.8 %); and vomiting/laxatives (9.5-6.6 %) for weight control. During 1999-2009, the prevalence of male students trying to lose weight increased (26.1-30.5 %). Among male students trying to lose or stay the same weight, the prevalence of exercising to control weight did not change during 1999-2003 and then increased (74.0-79.1 %) while the prevalence of taking diet pills/powders/liquids for weight control decreased (6.9-5.1 %) during 1999-2009. Weight management goals and behaviors changed during 1999-2009 and differed by subgroup. To combat the use of unhealthy weight control behaviors, efforts may be needed to teach adolescents about recommended weight management strategies and avoiding the risks associated with unhealthy methods.

  9. Seasonal and multi-annual variations of the North Dvina river input into the White Sea (Russia)

    2012-04-01

    The rivers are the main source of terrestrial material, including dissolved and particulate organic carbon (DOC and POC), into the seas and the oceans (Lisitzin, 1974). The multidisciplinary program "The White Sea System" (principal investigator A.P. Lisitzin) started in 2000 and continues till present. The main aim of this program is to investigate the fluxes of material from the continent and from air into this sub-Arctic sea in different seasons and years. There were more than 30 expeditions in this period of time. Two volumes of the collective monograph "The White Sea system" (in Russian) were published (2010 and 2012) with the results of the program. The aim of this presentation is to demonstrate the generalization of the data obtained in the expeditions on geochemistry of water and sediments and their fluxes into the sea. The distribution of suspended sediment depending on salinity was in many cases quite typical with the exponential decrease of its concentrations. But in several cases these dependences were untypical - with the concentration maximum at intermediate salinities. The estimations have shown that the losses of suspended sediments in the mixing zone in a whole year were near 23% that was much lower in comparing with many other estuaries of the great rivers in the World. The survey of the data on the distribution of DOC has shown its conservative or quasi-conservative behavior in the North Dvina estuary. Very untypical situation was observed in spring of 2003 when all the figurative points were divided in two independent groups - one with normal DOC concentrations (18-20 mg/l in river water) and another with very high concentrations - up to 70-75 mg/l (probably as a result of anthropogenic pollution) and conservative behavior in both groups. The estimates of the losses of dissolved and particulate Fe, Mn and several trace metals were obtained. So, such integral parameter of geochemical behavior of dissolved and particulate substances as their

    One of the primary roles of Fédération Internationale de Natation (FINA) is to promote athlete health. The planning and delivery of major international event medical services is carried out in collaboration with the Local Organizing Committee Medical Commission (LOCMC). Aspetar Orthopaedic and Sports Medicine Hospital provided the medical services to the 12th FINA World Swimming Championships (25 m) creating a unique opportunity for collaboration with FINA. The purpose of this paper is to review the planning and delivery of medical services and athlete health promotion projects during the 12th FINA World Swimming Championships (25 m) to facilitate the planning of future sporting events of this size and scope. The 12th FINA World Swimming Championships (25 m) hosted 974 athletes from 166 countries. The LOC medical team recorded all medical encounters-newly incurred (or acute exacerbations of chronic) injuries and illnesses as well as follow-up consultations. More than 90% of teams did not travel with a team physician and relied on the LOCMC for diagnosis and treatment of injuries and illnesses in athletes and accredited team officials. The LOC medical team had a total of 554 medical encounters: 385 therapy, 34 athlete injury, 65 athlete illness and 70 non-athlete encounters. The LOCMC in collaboration with FINA delivered comprehensive medical services to athletes, officials and spectators attending the 12th FINA World Swimming Championships (25 m). This review paper provides information relevant to the planning and delivery of LOCMC medical services for future international swimming events contributing to the FINA objective of promoting athlete health.

    Nabro volcano sits on the southern part of Danakil block to the east of the Afar depression, on the Arabian plate. On the 12th June 2011, Nabro volcano suddenly erupted after being inactive for 10,000 years. The eruption caused a 17-km-long lava flow, a 15-km-high ash cloud, and ranks as one of the largest emissions of SO2 since the Mt. Pinatubo (1991) event. This eruption creates an important opportunity to use seismicity and surface deformation measurements to understand the subsurface magmatic system and deformation of a hazardous, off axis caldera during continental rupture. We installed a network of 8 seismometers around Nabro caldera which began recording on the 31st August and tasked SAR acquisitions from TerraSAR-X (TSX) and Cosmo-SkyMed (CSK) satellites. The SAR images used for this study post date the eruption. We used TSX stripmap mode images from ascending and descending orbits. Using a small baseline approach, we used 25 images acquired between the 1st July 2011 to the 5th October 2012 on descending orbit 046, to create 34 interferograms. We complemented these with 19 images from ascending orbit 130 spanning the 6th July 2011 to the 10th October 2012 from ascending orbit 130, which we used to create 21 interferograms. We produced a velocity ratemap and timeseries using π-RATE showing subsidence of up to 25cm/yr centred on Nabro. We used a Monte-Carlo hybrid downhill simplex technique to invert the dataset and found the best fitting solution as a mogi source at 6.9 ±1.1 km depth, and located at a 13.35 (lat) and 41.69 (long). The time dependence observed is consistent with a viscoelastic relaxation around the magma chamber, following depletion. Concurrent with the TSX acquisitions, CSK imaged the volcano on a descending track between 26th June 2011 and 18th July 2012 within the ASI project SAR4Volcanoes, and 64 images were used to produce 171 interferograms which were inverted to form a timeseries using a SBAS approach.

    About 30% of high school students use energy drinks. Alcohol mixed with energy drinks (AmED) has been associated with higher rates of risky driving among college students. The purpose of this study was to: (a) examine AmED-use in a sample of high school students and (b) to specifically investigate differences in risky driving behaviors between 12th grade students who engaged in AmED-use and those who consumed alcohol only. Differences in risky driving behaviors were investigated by utilizing secondary data analyses of nationally representative data from the Monitoring the Future Study (N = 1305). 12th grade AmED users were significantly more likely to be in a motor vehicle accident (p <.001) and receive a ticket for a traffic violation (p <.05). Additionally, 12th grade AmED users were significantly less likely to wear a seatbelt as a driver or passenger (p <.001). Conclusions/Importance: Although this study does not link risky driving behaviors to specific drinking events, it does indicate a relationship between AmED-use and high-risk driving. Because traffic accidents are the highest cause of mortality among U.S. teenagers, drug education efforts to reduce high-risk driving behaviors should include information on the decision-making and synergistic effects of energy drinks when mixed with alcohol.

    2010-01-01

    Background Evidence of an association between employment and physical activity (PA) in youth has been mixed, with studies suggesting both positive and negative associations. We examined the association between employment and PA among U.S. high school students as measured by self-reported overall PA, vigorous exercise, and participation in school athletic teams. Methods We employed a secondary analysis using weighted linear regression to a sample of black and white 10th grade (n=12073) and 12th grade students (n=5500) drawn from the nationally representative cross-sectional 2004 Monitoring the Future Study. Results Overall, 36.5% of 10th and 74.6% of 12th grade students were employed. In multivariable analyses, 10th graders working >10 hours a week reported less overall PA and exercise and those working >20 hours a week reported less participation in team sports. Among 12th graders, any level of employment was associated with lower rates of team sports; those working >10 hours a week reported less overall PA; and those working >20 hours reported less exercise. Conclusions Employment at and above 10 hours per week is negatively associated with PA. Increasing work intensity may shed light on the decline of PA as adolescents grow older and merits further attention in research. PMID:20231752

    The purpose of this study was to determine publication rates of all abstracts submitted for presentation at the annual conference of the Pediatric Orthopaedic Society of North America (POSNA) comparing papers accepted for presentation with those that were not accepted and to determine the median times to publication and the mean impact factor of journals that published papers from the 2 groups. The titles and authors of all abstracts submitted for presentation to the POSNA for the years 2003 to 2005 were identified. To determine publication status, we conducted a computerized Pubmed search using the first author's name. If multiple publications were identified, the Boolean search operator AND was used to combine author names with key words. The title of each located published article was compared with the title of the abstract. If differences were noted, the abstract content was compared with the final publication. The journals, impact factor was determined using the journal citation report. The median time from conference presentation to publication was determined using a Kaplan-Meier survival analysis. Of 1191 abstracts submitted to the annual meetings of POSNA from the years 2003 through 2005, 440 (37%) were accepted for presentation. Acceptance of submitted abstracts increased from 30% in 2003 to 40% in 2005. Of the 1191 abstracts 599 (50%) were subsequently published by August 2009. The mean publication rate for abstracts accepted for presentation was 58.9% (259 of 440) compared with 45% (339 of 751) for rejected abstracts. The median time to publication of accepted abstracts was not significantly different when compared with that of rejected abstracts. The mean journal impact factor for accepted articles was 2.2 compared with 1.5 for rejected abstracts. The publication rates of abstracts submitted to POSNA is high compared with those of other international orthopaedic associations. The mean publication rate for accepted abstracts and rejected abstracts has

    Inter-annual to decadal sea level variations from tide gauge records along the Norwegian coast and in the Siberian Seas are examined for the period 1950 to present. A combination of observations and theory is used to explore the physical mechanisms responsible for the observed sea level variability. Tide gauge records are first grouped into 6 geographical regions: the Norwegian Coast, the Barents Sea, the Kara Sea, the Laptev Sea, the East Siberian Sea, and the Chukchi Sea. Then an average of sea level at tide gauges is computed for each region. All regions exhibit large decadal sea level variations (up to 20 cm). Sea level corrected for the inverse barometer effect is significantly correlated with the Arctic Oscillation index in all regions except in the East Siberian and Chukchi Seas. There is a coherent sea level signal that affects a region extending from Southwest Norway to the Kara Sea. Previous studies have found that sea level variability at the Norwegian coast is related to variations in the Norwegian Atlantic Current (NwAC), which are mainly driven by changes in the wind forcing over the region. Here we show that, apart from the contribution of the NwAC and the local wind, there is an additional contribution to the sea level variability at the Norwegian coast resulting from the poleward propagation of wind-driven sea level variations along the continental slope of the Northeast Atlantic. The fact that sea level variability in both the Barents and the Kara Seas is highly coherent with that in the Norwegian coast suggests propagation of sea level variations further north into these regions. Eastward of the Kara Sea, where the continental shelf is shallower, sea level variations are much larger than in the other regions and they are highly correlated (~0.75) with the local longshore wind.he average of sea level at 8 tide gauge stations on the Norwegian coast (black line) and a reconstruction of sea level (blue line) using a combination of the tide gauge at

    Background Recent reports of transmission interruption of Onchocerca volvulus, the causing agent of river blindness, in former endemic foci in the Americas, and more recently in West and East Africa, raise the question whether elimination of this debilitating disease is underway after long-term treatment of the population at risk with ivermectin. The situation in Central Africa has not yet been clearly assessed. Methods and findings Entomologic data from two former endemic river basins in North Cameroon were generated over a period of 43 and 48 months to follow-up transmission levels in areas under prolonged ivermectin control. Moreover, epidemiologic parameters of animal-borne Onchocerca spp. transmitted by the same local black fly vectors of the Simulium damnosum complex were recorded and their impact on O. volvulus transmission success evaluated. With mitochondrial DNA markers we unambiguously confirmed the presence of infective O. volvulus larvae in vectors from the Sudan savannah region (mean Annual Transmission Potential 2009–2012: 98, range 47–221), but not from the Adamawa highland region. Transmission rates of O. ochengi, a parasite of Zebu cattle, were high in both foci. Conclusions/significance The high cattle livestock density in conjunction with the high transmission rates of the bovine filaria O. ochengi prevents the transmission of O. volvulus on the Adamawa plateau, whereas transmission in a former hyperendemic focus was markedly reduced, but not completely interrupted after 25 years of ivermectin control. This study may be helpful to gauge the impact of the presence of animal-filariae for O. volvulus transmission in terms of the growing human and livestock populations in sub-Saharan countries.

    The 12th International Workshop on Plasma-Facing Materials and Components for Fusion Applications (PFMC-12) was held in Forschungszentrum Jülich (FZJ) in Germany in May 2009. This symposium is the successor to the International Workshop on Carbon Materials for Fusion Applications series. Between 1985 and 2003, 10 'Carbon Workshops' were organized in Jülich, Stockholm and Hohenkammer. After this time, the scope of the symposium was redefined to reflect the new requirements of ITER and the ongoing evolution of the field. The workshop was first organized under its new name in 2006 in Greifswald, Germany. The main objective of this conference series is to provide a discussion forum for experts from research institutions and industry dealing with materials for plasma-facing components in present and future controlled fusion devices. The operation of ASDEX-Upgrade with tungsten-coated wall, the fast progress of the ITER-Like Wall Project at JET, the plans for the EAST tokamak to install tungsten, the start of ITER construction and a discussion about the wall material for DEMO all emphasize the importance of plasma-wall interactions and component behaviour, and give much momentum to the field. In this context, the properties and behaviour of beryllium, carbon and tungsten under plasma impact are research topics of foremost relevance and importance. Our community realizes both the enormous advantages and serious drawbacks of all the candidate materials. As a result, discussion is in progress as to whether to use carbon in ITER during the initial phase of operation or to abandon this element and use only metal components from the start. There is broad knowledge about carbon, both in terms of its excellent power-handling capabilities and the drawbacks related to chemical reactivity with fuel species and, as a consequence, about problems arising from fuel inventory and dust formation. We are learning continuously about beryllium and tungsten under fusion conditions, but our

    Measurements of proton and helium spectra have been made in the energy range 10 to the 12th to 10 to the 14th eV. Large area thin emulsion calorimeters were used in the Japanese American Cooperative Emulsion Experiment balloon flight series. Power indices of the integral spectra for both nuclei are consistent with published data at lower energies. Absolute intensities are also consistent for helium and proton fluxes with extrapolations of previous data. No steepening of the proton spectrum is indicated.

    Based on measurements of unaccompanied charged hadron flux from 10 to the 11th to 10 to the 14th eV at mountain altitudes, the primary proton flux is estimated using recently determined proton-proton total cross sections from new measurements of the real part of the forward scattering amplitude at ISR, and Glauber theory to calculate proton-air inelastic cross section. The derived spectrum agrees well with extrapolation of the direct measurements below 2 times 10 to the 12th eV without change of slope.

  13. Seasonal and annual deposition rates of sulphur, nitrogen and chloride species to an oak forest in north-eastern austria (wolkersdorf, 240 m a.s.l.)

    NASA Astrophysics Data System (ADS)

    Puxbaum, Hans; Gregori, Martin

    Dry deposition estimates of sulphur, nitrogen and chloride components to an oak forest in north-eastern Austria were performed using an "Inferential model." The deposition calculations were performed with a modified Hicks et al. (1985) model based on chemical measurement data with 0.5 h (SO 2, NO, NO 2) and 24 h (HCl, HNO 3, NH 3, particulate chloride, nitrate, sulphate and ammonium) time resolution. Annual dry deposition rates of sulphur (SO 2+pSO 4) were estimated to amount around 13 kg ha -1, of oxidised nitrogen (NO+NO 2+HNO 3+pNO 3) 8.4 kg ha -1, of reduced nitrogen (NH 3+pNH 4) 5.6 kg ha -1 and of chloride (HCl+pCl) 2.1 kg ha -1. The relative contribution of dry to total (dry+wet) deposition is 68% for sulphur, 77% for oxidised nitrogen, 55% for reduced nitrogen and 40% for chloride species. Total deposition of sulphur and reduced nitrogen species showed good agreement with data from throughfall measurements and a canopy exchange model. For oxidised nitrogen species the inferential modeling approach yielded a considerably higher deposition which could be explained by the inability of the canopy exchange model to account for stomatal uptake of NO 2. A comparison of dry and wet fluxes of sulphur and nitrogen species at European and U.S. sites indicates that in both environments large regional differences occur. Thus the hypothesis, that European forests receive substantially higher inputs of "major ions" than U.S. forests ( Lindberg et al., 1990) cannot be generalised. "Dry+wet" deposition of nitrogen species at two Austrian sites is well within the range of deposition at 11 forested sites in the U.S., while at one Austrian site it is slightly higher than the highest N-deposition reported for U.S. sites. Compared sites from the U.S. are from the Mountain Cloud Chemistry Project and the Integrated Forest Study ( Lovett and Lindberg, 1993).

    ]. This dataset provides comprehensive monthly statistics on the wind meteorological regime at the stations of interest in a given range of altitudes. Based on long-term source observational data, the dataset is assumed being representative up to date, which allowed us to estimate monthly pollutant fluxes for the years 2006-2008 over segments of the Russian border and its whole [4]. In the current phase of our study, we calculate the inter-annual variations in the transboundary pollutant fluxes for 2000-2012 using longer-term EANET data and transient changes in air mass fluxes derived from the meteorological wind fields from ERA INTERIM re-analysis [5]. We gauge similar average air transport terms and dynamics from the statistical and reanalysis data, which bolsters our earlier findings. The reanalysis data, being naturally more variable, convolutes the variations in net air fluxes and pollutant concentrations into several episodes we emphasise, in addition to the integral pollutant transfer terms we estimate. At last, we discuss on the possibility of climate change effect on the flux strength and dynamics together with regional air quality tendencies in North-East Asia countries.

    As climate change intensifies, increased temperatures and altered precipitation will make water, a limited resource in the arid southwestern United States, even scarcer in many locations. The USDA Southwest Regional Climate Hub (SWRCH) developed Climate Change and the Water Cycle, an engaging and scientifically rigorous education unit for 6th -12th grade students. The unit is aligned with Common Core State Standards and Next Generation Science Standards. Nine activities can be conducted over 10 instruction hours. Each activity can also stand alone. In partnership with SWRCH, the Asombro Institute for Science Education developed the unit. Each activity was reviewed by an educator for educational practices and by a scientist for scientific accuracy. The unit was pilot tested with 524 students in 2014, and pre- and post-tests were administered. Ninety-one percent of students were able to name a greenhouse gas on the post-test, compared to only 48% on the pre-test. On the post-test, 86% of students identified the relationship between average global temperature and carbon dioxide levels in the atmosphere, compared to only 52% on the pre-test. A student commented: "I loved all of the activities! They are fun and help us understand about what goes on in the world." Educators who participated in pilot testing said: "the entire curriculum is great, but I was particularly impressed with the progression of ideas and the variety of lessons," and "students could see the relevance and importance of these real life issues." Anyone interested in using the unit to host workshops for teachers in southwestern states should contact Asombro for more information (information@asombro.org).

    The consumption of alcohol mixed with energy drinks (AmED) is a risky drinking behavior, most commonly studied using college samples. We know little about rates of AmED use and its associations with other risk behaviors, including unsafe driving, among high school students. This study examined the prevalence and correlates of AmED use among high school seniors in the United States. Nationally representative analytic samples included 6,498 12th-grade students who completed Monitoring the Future surveys in 2012 and 2013. Focal measures included AmED use, sociodemographic characteristics, academic and social factors, other substance use, and unsafe driving (i.e., tickets/warnings and accidents) after alcohol consumption. Approximately one in four students (24.8%) reported AmED use during the past 12 months. Rates of AmED use were highest among males and white students. Using multivariable logistic regression models controlling for sociodemographic characteristics, results indicate that students who cut class, spent more evenings out for fun and recreation, and reported binge drinking, marijuana use, and illicit drug use had a greater likelihood of AmED use. AmED use was also associated with greater odds of alcohol-related unsafe driving, even after controlling for sociodemographic, academic, and social factors and other substance use. AmED use among 12th-grade students is common and associated with certain sociodemographic, academic, social, and substance use factors. AmED use is also related to alcohol-related unsafe driving, which is a serious public health concern. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Using multivariable logistic regression models controlling for sociodemographic characteristics, results indicate that students who cut class, spent more evenings out for fun and recreation, and reported binge drinking, marijuana use, and illicit drug use had a greater likelihood of AmED use. AmED use was also associated with greater odds of alcohol-related unsafe driving, even after controlling for sociodemographic, academic, and social factors, and other substance use. Conclusions AmED use among 12th-grade students is common and associated with certain sociodemographic, academic, social, and substance use factors. AmED use is also related to alcohol-related unsafe driving, which is a serious public health concern. PMID:25907654

  20. [The effect of maternal dexamethasone treatment after the 12th week of pregnancy on fetal genital development in adrenogenital syndrome with 21-hydroxylase deficiency].

    Prenatal treatment with dexamethasone starting with gestation week 5 has been proposed to prevent virilization of female fetuses with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. We report dexamethasone treatment in a mother during her third pregnancy; this treatment could not be started before the 12th week of gestation. The second child (index case) had a simple virilizing 21-hydroxylase deficiency CAH and Prader IV genitalia. Because after amniocentesis a normal female karyotype and HLA identity with the index case were found, the dexamethasone treatment (3 x 0.5 mg/die) was continued until delivery.-In contrast to patients with salt-wasting CAH, the 17-alpha-hydroxyprogesterone level in the amniotic fluid was within the normal range. Decreased maternal plasma and urine estriol concentrations, as well as the plasma cortisol values, demonstrated adequate suppression of the fetal and maternal adrenal gland. No side effects were found in the mother as a result of the dexamethasone treatment. The newborn had virilization of the external genitalia according to Prader III but without hypertrophy of the clitoris. The degree of rugated scrotum was less marked in relation to the index case and the sinus urogenitalis was more distally shifted. Thus, surgery on the clitoris could be avoided. The conditions for further surgery (vaginoplasty) could probably be improved. Therefore, dexamethasone treatment of a mother with a female CAH fetus due to 21-hydroxylase deficiency seems to be justified starting at the 12th week of gestation. However, the optimal beginning of therapy is in early pregnancy.

  6. Responses of the Bering-Chukchi Shelf Circulation at Synoptic and Inter-Annual Time Scales to the Location, Strength, and Direction of North Pacific and Western Arctic Winds

    We develop a conceptual model of the closely co-dependent Bering shelf, Bering Strait, and Chukchi shelf circulation fields by evaluating the effects of wind stress over the North Pacific and western Arctic. This conceptual model suggests Bering Strait transport anomalies are primarily set by the longitudinal location of the Aleutian Low, which drives oppositely signed anomalies at synoptic and annual time scales. Synoptic time scale variations in shelf currents result from local wind forcing and remotely generated continental shelf waves, whereas annual variations are driven by basin scale adjustments to wind stress that alter the magnitude of the along-strait (meridional) pressure gradient. In particular, we show that storms centered over the Bering Sea excite continental shelf waves on the eastern Bering shelf that carry northward velocity anomalies northward through Bering Strait and along the Chukchi coast. The integrated effect of these storms tends to decrease the northward Bering Strait transport at annual to decadal time scales by imposing cyclonic wind stress curl over the Aleutian Basin and the Western Subarctic Gyre. Ekman suction then increases the water column density through isopycnal uplift, thereby decreasing the dynamic height, sea surface height, and along-strait pressure gradient. Storms displaced eastward over the Gulf of Alaska generate an opposite set of Bering shelf and Aleutian Basin responses. While Ekman pumping controls Canada Basin dynamic heights [Proshutinsky et al., 2002], we do not find evidence for a strong relation between Beaufort Gyre sea surface height variations and the annually averaged Bering Strait throughflow. Over the western Chukchi and East Siberian seas easterly winds promote coastal divergence, which also increases the along-strait pressure head, as well as generates shelf waves that impinge upon Bering Strait from the northwest.

    Observation and evaluation of STEM graduate students from Mississippi State University communicating their research of the Earth and Space Sciences in rural 7th-12th grade classrooms participating in the Initiating New Science Partnerships in Rural Education (INSPIRE) NSF GK-12 project. The methods they utilize to communicate their STEM research includes introducing new technologies and inquiry based learning experiences. These communication experiences have been observed and evaluated using two observational systems, the Mathematics Science Classroom Observational Profile System (M-SCOPS) and the Presentation Skills Protocol (PSP). M-SCOPS has been used over the first three years of the project to evaluate what Earth and Space research the STEM graduate students communicate in classroom activities along with how they are introducing STEM research through a variety of communication methods and levels of understanding. PSP, which INSPIRE began using this year, evaluates and provides feedback to the STEM graduate students on their communication during these classroom experiences using a rubric covering a range of skills for successful communication. PSP also allows the participating INSPIRE teacher partners to provide feedback to the STEM graduate students about development of their communication skills over the course of the year. In addition to feedback from the INSPIRE project and participating teachers, the STEM graduate students have the opportunity to evaluate their personal communication skills through video documentation to determine specific skills they would like to improve. Another area of research to be discussed is how the STEM graduate students communicating Earth and Space sciences research in the participating classrooms is impacting student attitudes about science and mathematics over the last three years. Student Attitudinal Surveys (SAS) are administered as a pre-evaluation tool in the fall when the STEM graduate students first enter into their

    The CTUIR North Fork John Day River Basin Anadromous Enhancement Project (NFJDAFEP) identified and prioritized stream reaches in The North Fork John day River basin for habitat improvements during the 2000 project period. Public out reach was emphasized during this first year of the project. We presented multiple funding and enhancement options to landowners. We concentrated on natural recovery methods, riparian fencing and off-stream livestock water developments. Under this BPA contract four riparian easements were signed protecting almost 5 miles of tributary streams. There are nine offstream water developments associated with these easements. Some landowners chose to participate in other programs based on Tribal outreach efforts. Two landowners chose NRCS programs for enhancement and one chose OWEB as a funding source. Two landowners implemented there own enhancement measures protecting 3 miles of stream. Cooperation between the NRCS/FSA/SWCDs and the Tribe to create joint projects and develop alternative funding scenarios for riparian enhancement was a major effort. The Tribe also worked with the North Fork John Day Watershed Council, USFS and ODFW to coordinate projects and support similar projects throughout the John Day Basin. We provided input to the John Day Summary prepared for the NWPPC by ODFW. The Tribe worked with the Umatilla National Forest on the Clear Creek Dredgetailings Rehabilitation project and coordinated regularly with USFS Fisheries, Hydrology and Range staff.

    The CTUIR North Fork John Day River Basin Anadromous Enhancement Project (NFJDAFEP) identified and prioritized stream reaches in The North Fork John day River basin for habitat improvements during the 2000 project period. Public outreach was emphasized during this first year of the project. During the past year we concentrated on satisfying landowner needs, providing cost share alternatives, providing joint projects and starting implementation. We presented multiple funding and enhancement options to landowners. We concentrated on natural recovery methods, riparian fencing and offstream livestock water developments. Under this BPA contract four riparian easements have been signed protecting almost 5 miles of tributary streams. There are nine offstream water developments associated with these easements. Some landowners chose to participate in other programs based on Tribal outreach efforts. Some landowners chose NRCS programs for enhancement and others chose OWEB as a funding source. The exact amount of stream protection due to other funding sources probably exceeds that by BPA, however most would not have entered any program without initial Tribal outreach.

    To draw attention to the necessity of considering differences in the digestibility of carbohydrates, and more specifically of starch, a symposium was held at the 12th European Nutrition Conference (FENS), which took place in Berlin from October 20 to 23, 2015. The purpose of this session was to present the consolidated knowledge and recent advances regarding the relationship between slow-release carbohydrates, metabolic responses, and public health issues. Three main topics were presented: 1) the definition of, sources of, and recognised interest in the glycaemic response to slowly digestible starch (SDS); 2) clinical evidence regarding the physiological effects of slow-release carbohydrates from cereal foods; and 3) interest in reducing the postprandial glycaemic response to help prevent metabolic diseases. Foods with the highest SDS content induce the lowest glycaemic responses, as the starch is protected from gelatinisation during processing. In humans, high-SDS food consumption induces slower glucose release, lower postprandial insulinaemia, and stimulation of gut hormones. Moreover, postprandial hyperglycaemia is an independent risk factor for type two diabetes mellitus (T2DM) and cardiovascular disease (CVD). Therefore, given the plausible aetiologic mechanisms, we argue that postprandial glucose levels are relevant for health and disease and represent a meaningful target for intervention, for example, through dietary factors. This symposium was organised by Mondelez International R&D.

    In the authors' previous investigations, they established that the tumorous cell lines SK-BR-3 (breast cancer), LAN-1 (neuroblastoma), and a heterotransplant of malignant melanoma Jal contain transforming genes of Ha-ras type. Now, the authors report their results using restriction endonucleases of MspI and HpaII restriction to study nucleotide sequences 5'-CCGGC-3' and 3'GGCCG-5', which contain the 12th codon of GGC for the amino acid glycine in the normal allele of c-Ha-rasl in the three tumors listed above, in addition to human adenocarcinoma of the stomach (CaVSt) and normal cells corresponding to them. For hybridization of MspI/HpaII, fragments of chromosomal DNA isolated from cell lines SK-BR-3, and LAN-1, Ja-1 heterotransplant, and stomach adenocarcinoma CaVSt, the XmaI section of EJ oncogene, c-Ha-rasl (plasmid pEJ 6.6), labeled with /sup 32/P was used in down-translation reaction. Hybridization was performed in 3 x SSC buffer containing 5x Deinhardt's reagent and 10% dextran sulfate at 68/sup 0/C for 16-18 h. Washing of filters was conducted under rigid conditions. For autoradiography, Kodak XR-5 x-ray film in cartridges with reinforcing shields was used at -70/sup 0/C, exposure time of four to six days.

    One or more of three intense and persistent droughts impacted some Native American cultures in the early-11th, middle-12th and late-13th centuries, including the Anasazi, Fremont, Lovelock, and Mississippian (Cahokian) prehistorical cultures. Tree-ring-based reconstructions of precipitation and temperature indicate that warm drought periods occurred between AD 990 and 1060, AD 1135 and 1170, and AD 1276 and 1297. These droughts occurred during minima in the Pacific Decadal Oscillation and may have been associated with positive values of the Atlantic Multidecadal Oscillation. Each of the Native American cultures was supported, to a greater or lesser degree, by precipitation-dependent resources. Both the Four Corners region and Cahokia were sites of intense growth between about AD 1050 and 1130, and by AD 1150, cultures in both regions were undergoing stress. By AD 1300 the Anasazi and Fremont cultures had collapsed and their residual populations had either left their homelands or withered. In the case of Fremont populations, the AD 990-1060 drought may have had the greatest impact. This drought also may have affected the Anasazi, for it was at the end of this drought that some people from Chaco migrated to the San Juan River valley and founded the Salmon Ruin great house. Detailed data do not exist on the number of Lovelock habitation sites or populations over time; however, Lovelock populations appear to have retreated from the western Great Basin to California by AD 1300 or shortly thereafter.

  7. Longitudinal Study of Career Cluster Persistence from 8th Grade to 12th Grade with a Focus on the Science, Technology, Engineering, & Math Career Cluster

    NASA Astrophysics Data System (ADS)

    Wagner, Judson

    Today's technology driven global economy has put pressure on the American education system to produce more students who are prepared for careers in Science, Technology, Engineering, and Math (STEM). Adding to this pressure is the demand for a more diverse workforce that can stimulate the development of new ideas and innovation. This in turn requires more female and under represented minority groups to pursue future careers in STEM. Though STEM careers include many of the highest paid professionals, school systems are dealing with exceptionally high numbers of students, especially female and under represented minorities, who begin but do not persist to STEM degree completion. Using the Expectancy-Value Theory (EVT) framework that attributes student motivation to a combination of intrinsic, utility, and attainment values, this study analyzed readily available survey data to gauge students' career related values. These values were indirectly investigated through a longitudinal approach, spanning five years, on the predictive nature of 8 th grade survey-derived recommendations for students to pursue a future in a particular career cluster. Using logistic regression analysis, it was determined that this 8 th grade data, particularly in STEM, provides significantly high probabilities of a 12th grader's average grade, SAT-Math score, the math and science elective courses they take, and most importantly, interest in the same career cluster.

    We describe the development and validation of a method for the quantification of drugs of abuse, using gas chromatography-mass spectrometry (GC/MS), in human placenta. Concentration ranges covered were 5-500 ng/g for amphetamine, methamphetamine, MDMA, methadone, cocaine, benzoylecgonine, cocaethylene, morphine, 11-nor-9-carboxy-delta-9-tetrahydrocannabinol, nicotine, and cotinine. Intra-assay and inter-assay imprecisions were less than 15.7% for lower quality control samples and less than 14.9% for medium and high quality control samples. Recovery range was 36.2-83.7%. Placenta samples were kept at -80 degrees C until analysis; analytes were stable after three freeze-thaw cycles (samples stored at -20 degrees C). This accurate and precise assay has sufficient sensitivity and specificity for the analysis of specimens collected from women who voluntarily terminated their pregnancy at 12th week of gestation. The method has proven to be robust and accurate for the quantification of the principal recreational drugs of abuse in this period of the prenatal life. This is the first report that highlights the presence of drugs of abuse during the first trimester of gestation.

    The purpose of this study was to determine the proportion of paper (podium) presentations at the 2006-2010 Arthroscopy Association of North America (AANA) annual scientific meetings that were ultimately published in a peer-reviewed journal. Furthermore, we aimed to evaluate whether the level of evidence correlated with the publication rate of these presentations or the impact factor (IF) of the publishing journal. Paper presentations from the 2006-2010 AANA annual meetings were included for evaluation. Clinical studies were graded for quality using the level of evidence by 2 independent reviewers. A comprehensive strategy was used to search the databases PubMed, Medline, and Embase for publications in scientific journals that corresponded to the presentations and were published within 5 years of the presentation date. Three hundred twenty-eight presentations were evaluated. Overall, 179 peer-reviewed publications corresponding to particular meeting presentations were identified, for a 5-year publication rate of 55%. There was no correlation between the publication rate and the level of evidence (P = .836), the type of study (P = .628), or the joint of focus (P = .07) of the presentations. The mean IF of journals that published Level I studies (4.8 [standard error, 2.3]) was significantly higher than the mean IF of journals that published Level II, III, or IV studies (2.58 [standard error, 0.10]) (P = .017). Between 2006 and 2010, presentations of the highest level of evidence at AANA meetings were subsequently published at a similar rate to presentations of lower levels of evidence, albeit in journals with higher IFs. This study is an important initial evaluation of the ultimate clinical impact of AANA meeting presentations. The study type, joint of focus, and level of evidence of the presentations all had no correlation with the rate at which these presentations were ultimately published.

  18. Integrated Analysis of the 12th January 2010, Mw 7.0, Haiti Earthquake Using InSAR, MAI, GPS, and Seismic Data

    NASA Astrophysics Data System (ADS)

    The Haiti earthquake, Mw 7.0, 12th January 2010, caused widespread destruction and resulted in more than 230,000 deaths. It is believed to have occurred on previously unknown fault(s), raising many questions concerning the tectonics and seismic hazard in this region. While accurate source models are key for robust seismic hazard assessments, existing source models for the Haiti earthquake from various datasets - geodetic (Calais et al., 2010), seismic (Nettles and Hjorjleifsdottir, 2010) and a combination of the two (Hayes et al., 2010) - show discrepancies, particularly concerning the fault geometry. We investigate these discrepancies using multiple aperture InSAR (MAI) data, along with seismo-geodetic analyses based on a new joint earthquake source inversion approach. Similar to previous geodetic models of this event, this study includes measurements of horizontal and line of sight displacement from GPS and InSAR data, respectively. However, we also extract further horizontal (along-track) measurements from the InSAR data using an updated MAI processing flow, incorporating flat-Earth and topographic phase corrections (Jung et al., 2009) . Despite the additional geodetic measurements, part of the signal is underwater, and thus seismic data (teleseismic long-period body and surface waves) are also included to further constrain the source parameters. We carry out geodetic and seismic-only inversions, as well as novel joint inversions taking, for the first time, realistic 3D Earth structure into account when modelling the seismic data. Initial results suggest that the addition of MAI and GPS data to the source inversions helps better constrain the strike and dip angle. However, the dip of our model is shallower (52°) than existing source models (60° - 70°) and the best fitting fault is buried ~ 4 km deeper than previously reported. We explore and discuss the implications of these findings in terms of earthquake slip distribution, mechanism and its tectonic context.

    Approximately 30% of high school students use energy drinks. Alcohol use and alcohol mixed with energy drink use (AmED) is associated with risky behavior, including non-medical prescription stimulant use. We assessed alcohol-only, AmED and non-medical prescription stimulant use among 12th grade students in the U.S. using a nationally representative secondary data from the 2012 Monitoring the Future Study. Wilcoxon-Mann-Whitney tests and logistic regression analyses were used to determine differences in non-medical prescription stimulant use by students who used alcohol-only versus AmED and to identify covariates of non-medical prescription stimulant use. Pearson-product moment coefficients were used to determine strength of variable relationships. Significant differences were found in frequency of Ritalin (p < .001, Cohen's d = .23) and Adderall (p < .001, Cohen's d = .32) use between alcohol-only students and AmED students. Greater frequency of AmED use was also associated with greater frequency of Ritalin use (r = .293, p < .001) and Adderall use (r = .353, p < .001). Males (b = .138, OR = 1.148) were more likely to use prescription stimulants non-medically than females. This study highlights the need to better understand influences on non-medical prescription stimulant, energy drink and AmED use, as the combined effects of stimulants contained in energy drinks and the depressant effects of alcohol appear to be associated with increased non-medical prescription stimulant use. Research on the influential factors related to energy drinks, alcohol, and non-medical prescription stimulants will help practitioners to more appropriately design prevention and intervention strategies addressing these high-risk behaviors.

  20. An analysis of 12th-grade students' reasoning styles and competencies when presented with an environmental problem in a social and scientific context

    NASA Astrophysics Data System (ADS)

    Yang, Fang-Ying

    This study examined reasoning and problem solving by 182 12th grade students in Taiwan when considering a socio-scientific issue regarding the use of nuclear energy. Students' information preferences, background characteristics, and eleven everyday scientific thinking skills were scrutinized. It was found most participants displayed a willingness to take into account both scientific and social information in reasoning the merits of a proposed construction of a nuclear power plant. Students' reasoning scores obtained from the "information reasoning style" test ranged from -0.5 to 1.917. And, the distribution was approximately normal with mean and median at around 0.5. For the purpose of categorization, students whose scores were within one standard deviation from the mean were characterized as having a "equally disposed" reasoning style. One hundred and twenty-five subjects, about 69%, belonged to this category. Students with scores locating at the two tails of the distribution were assigned to either the "scientifically oriented" or the "socially oriented" reasoning category. Among 23 background characteristics investigated using questionnaire data and ANOVA statistical analysis, only students' science performance and knowledge about nuclear energy were statistically significantly related to their information reasoning styles (p < 0.05). The assessed background characteristics addressed dimensions such as gender, academic performances, class difference, future education, career expectation, commitment to study, assessment to educational enrichment, family conditions, epistemological views about science, religion, and the political party preference. For everyday scientific thinking skills, interview data showed that both "scientifically oriented" students and those who were categorized as "equally disposed to using scientific and social scientific sources of data" displayed higher frequencies than "socially oriented" ones in using these skills, except in the use of

    Background There is considerable interest in determining whether mass drug administration (MDA) with ivermectin for onchocerciasis control will eliminate coendemic lymphatic filariasis (LF). The objective of this study was to determine the prevalence of LF microfilaremia in onchocerciasis endemic districts that had received 7 years of MDA with ivermectin. Method Three villages with a 2010 LF circulating antigenaemia prevalence (determined in a mapping exercise using immunochromatography tests) ranging from 23 to 56% were surveyed for the presence of Wuchereria bancrofti microfilaria (mf) in 2012. These villages had been treated with ivermectin MDA for onchocerciasis with reported total population coverage of ≥65%. A total of 774 residents aged 2 years and above, of both genders, provided 60 μl nocturnal blood samples between 10 pm and 2 am. Standard thick smears were prepared and examined microscopically after Giemsa staining for the presence of W. bancrofti mf. Results The mean mf prevalence was 4.7% (village range 1.1–11.0%). The mean mf density was 9.8 mf/60 μl (village range 9–13.1) among the positive individuals. Children in the 2–4-year-old and 5–9-year-old age groups were infected suggesting transmission occurred during the MDA period. A village level review of MDA treatment coverage records showed an average total population coverage of 66.4% over a 7-year period, but with a considerable range of annual coverage (43.0–89.9%). In addition, village level treatment coverage data were missing from the village with the highest mf prevalence (11%) for 2 of the 7 years. Conclusion 7 years of annual mass treatment with ivermectin monotherapy for onchocerciasis did not interrupt LF transmission. In expanding the onchocerciasis ivermectin MDA programme to include LF, albendazole should be added and treatment coverage improved. PMID:26878935

    The Mt. Logan, Yukon, Canada summit plateau (PR Col; 5300 m.a.s.l.) ice core has been continuously sampled at high resolution (2-3 cm/sample) by a novel ice core melting system with discrete sampling, and analyzed for 8 major ions and 35 trace elements. Co-registered, sub-annual timeseries covering the past 500 years reveal seasonal aerosol fluctuations dominated by dust, with sea-salt contributing less than 5% of sulfate and calcium concentrations. Dating of the top 500 years of the record is by annual layer counting. Concentration spikes of sulfate greater than three times the standard deviation (60 ppb) above the mean (75 ppb) correspond in time with historical explosive volcanic eruptions. Sulfate spikes corresponding in time with large (VEI>4) historical Alaskan eruptions, including Katmai (1912) and St. Augustine (1986), are commonly associated with concentration and crustal enrichment factor spikes in lead, cadmium, antimony, copper, zinc, bismuth and thallium an order of magnitude above background (non-volcanic event) values. Sulfate spikes corresponding in time to large eruptions from distant volcanoes, including Agung (1963), do not show a corresponding rise in heavy metal concentrations. Apart from the periodic spikes in concentration, heavy metal timeseries largely mirror those of the major dust species (Al, Fe), but maintain significantly elevated crustal enrichment factors, probably due primarily to quiescent degassing of volcanoes. Such datasets are necessary to understand the cycling of heavy metals in the free troposphere, including the relative source strength of explosive eruptions vs. quiescent volcanic degassing, and the relative strength of natural vs. anthropogenic sources.

    The prevalence and intensity of infection with Onchocerca volvulus were assessed in population surveys in nine villages, situated at different distances from Simulium damnosum s.l. breeding sites. The prevalence varied from 48 to 89%, the arithmetic mean densities of microfilariae per skin snip were between 16 and 109, and severe ocular lesions were found in from 1 to 22% of patients. Annual Transmission Potentials (ATP) were measured for up to three years in the near vicinity of nine villages at several fly-catching sites. Weighted means of the ATP over the three years, and of the sojourn times of the human population, were calculated at three of the villages, where the prevalence of onchocerciasis was 51, 61 and 89%. An average ATP of 100 larvae or less in the head, thorax and abdomen of the flies was associated with an onchocerciasis prevalence of 50 to 60%, a mean microfilarial density below 40 microfilariae per skin-snip, less than 5% of ocular lesions, and no onchocercal blindness. This value might therefore be considered to be an indication of the level to which the transmission must be reduced in the savanna in order to prevent the occurrence of severe ocular lesions or blindness. It is lower than the present level accepted by the Onchocerciasis Control Programme in the Volta River Basin.

    We have made substantial progress toward our objectives outlined in our BPA supported proposal entitled 'Columbia River Basin Juvenile Salmonids: Survival and Growth in the Columbia River Plume and northern California Current' which we report on herein. During 2008, we were able to successfully conduct 3 mesoscale cruises. We also were able to conduct 7 biweekly predator cruises, along with substantial shore-based visual observations of seabirds. Detailed results of the mesoscale cruises are available in the Cruise Reports and summarized in the next section. We have taken a proactive approach to getting the results of our research to fisheries managers and the general public. We have begun to make annual predictions based on ocean conditions of the relative survival of juvenile coho and Chinook salmon well before they return as adults. This is based on both biological and physical indicators that we measure during our surveys or collect from outside data sources. Examples of our predictions for 2009 and 2010 are available on the following web site: http://www.nwfsc.noaa.gov/research/divisions/fed/oeip/a-ecinhome.cfm.

    The 8.0R earthquake that struck Sichuan on the 12th of May 2008, in the district of Chengdu of Southern China resulted in tenths of thousands casualties, the complete destruction of many towns and extended damages to public works. The earthquake was triggered by a reverse fault of NE-SW trend, more than 100 km long, that divides morphologically the affected area in two sections, the eastern one with mild low topography and the western one with intense relief representing the boundary of Tibet Mountains. This mountainous section is characterized by a rich drainage network that drains the greater region of the Tibet plateau. Along the trace of this high-stand for thousands of years numerous hydraulic works have been attempted in order to manage the water supply. Especially during the past decades, 400 small and large dams have been constructed. The main dam is the Zipingpu dam. It is a Concrete Face Rockfill Dam (CFRD) that has a height of 150m, a capacity of 1.2 billion m3 and includes a hydroelectric plant of 3.4 billion Kwh power. The Zipingpu dam is located 10km east of the earthquake epicenter and after the earthquake of 8.0R, the following failures were recorded: (i) Subsidence of the crown in the central part of the dam, of the order of 50cm in relation to the side survey control points, (ii) Deformation of the lower face of the dam, an area of approximately 1000 m2, (iii) Deviations and deformations of the construction elements throughout the face of the dam, (iv) Widening of construction joints (approximately 15 cm on the upper face), (v) Extended massive landslides throughout the reservoir, and (vi) Landslides on both left and right abutments of the dam causing further damages to secondary constructions. After the evaluation of the dam damages, the discharge of the reservoir was ordered through the emergency spillway in order to minimize the risk of a potential disaster for the nearby towns and especially Dujiangyan. Finally, the causes of the failures are

    The skill of supra-12th rib mini-flank approach for open partial nephrectomy (MI-OPN) provides an advanced operative method for renal tumor. Compared with laparoscopic and robotic surgery, it may be a feasible selection for the complex renal tumors. We describe our techniques and results of MI-OPN in complex renal tumors with high RENAL nephrometry score (RENAL nephrometry score ≥10). Fifty-five patients diagnosed with renal tumors between January 2009 and July 2013 were included in this study. Eligibility criteria comprised of patients with complex renal tumor (RENAL score ≥10) being candidates for partial nephrectomy (PN). All patients received MI-OPN and all surgeries were performed by a single urologist. The preoperative workup comprised of medical history, physical examination, and routine laboratory tests. Serum creatinine was recorded preoperatively and 2 to 3 months after operation. Operative time, ischemia time, blood loss, operative and postoperative complications, renal function, and pathology parameters were recorded. MI-OPN was successfully performed in all cases. Mean tumor size was 4.7 cm (range: 2.5-8.1). Mean warm ischemia time was 28.1 minutes (range: 21-39), mean operative time was 105 minutes (range: 70-150) and mean estimated blood loss was 68 mL (range: 10-400). Mean postoperative hospital stay was 6.5 days (range: 5-12). Postoperative complications were found in 3 patients (5.5%). The mean pre- and postoperative serum creatinine levels were 76.2 μmol/L (range: 47-132) and 87.1 μmol/L (range: 61-189) with significant difference (P = 0.004). The mean pre- and postoperative estimated glomerular filtration rate (eGFR) were 91.5 (range: 34-133) and 82.5 (range: 22-126.5), respectively with significant difference (P = 0.024). In an average follow-up of 19.9 months (range: 8-50), no local recurrence or systemic progression occurred. In conclusion, MI-OPN can combine the benefits of both minimal invasive and traditional open

    Initiating New Science Partnerships in Rural Education (INSPIRE), a NSF Graduate K-12 (GK-12) program at Mississippi State University, pairs STEM graduate students with local K-12 teachers to bring new inquiry and technology experiences to the classroom (www.gk12.msstate.edu). The graduate fellows prepare lessons for the students incorporating different facets of their research. The lessons vary in degree of difficulty according to the content covered in the classroom and the grade level of the students. The focus of each lesson is directed toward the individual research of the STEM graduate student using inquiry based designed activities. Scientific instruments that are used in STEM research (e.g. SkyMaster weather stations, GPS, portable SEM, Inclinometer, Soil Moisture Probe, Google Earth, ArcGIS Explorer) are also utilized by K-12 students in the activities developed by the graduate students. Creativity and problem solving skills are sparked by curiosity which leads to the discovery of new information. The graduate students work to enhance their ability to effectively communicate their research to members of society through the creation of research linked classroom activities, enabling the 7-12th grade students to connect basic processes used in STEM research with the required state and national science standards. The graduate students become respected role models for the high school students because of their STEM knowledge base and their passion for their research. Sharing enthusiasm for their chosen STEM field, as well as the application techniques to discover new ideas, the graduate students stimulate the interests of the classroom students and model authentic science process skills while highlighting the relevance of STEM research to K-12 student lives. The measurement of the student attitudes about science is gathered from pre and post interest surveys for the past four years. This partnership allows students, teachers, graduate students, and the public to

    Terrestrial ecosystems greatly contribute to carbon (C) emission reduction targets through photosynthetic C uptake.Net primary production (NPP) represents the amount of atmospheric C fixed by plants and accumulated as biomass. The Three-North Shelterbelt Program (TNSP) zone accounts for more than 40% of China’s landmass. This zone has been the scene of several large-scale ecological restoration efforts since the late 1990s, and has witnessed significant changes in climate and human activities.Assessing the relative roles of different causal factors on NPP variability in TNSP zone is very important for establishing reasonable local policies to realize the emission reduction targets for central government. In this study, we examined the relative roles of drought and land cover conversion(LCC) on inter-annual changes of TNSP zone for 2001–2010. We applied integrated correlation and decomposition analyses to a Standardized Evapotranspiration Index (SPEI) and MODIS land cover dataset. Our results show that the 10-year average NPP within this region was about 420 Tg C. We found that about 60% of total annual NPP over the study area was significantly correlated with SPEI (p<0.05). The LCC-NPP relationship, which is especially evident for forests in the south-central area, indicates that ecological programs have a positive impact on C sequestration in the TNSP zone. Decomposition analysis generally indicated that the contributions of LCC, drought, and other Natural or Anthropogenic activities (ONA) to changes in NPP generally had a consistent distribution pattern for consecutive years. Drought and ONA contributed about 74% and 23% to the total changes in NPP, respectively, and the remaining 3% was attributed to LCC. Our results highlight the importance of rainfall supply on NPP variability in the TNSP zone. PMID:27348303

  12. Evaluating turbidity and suspended-sediment concentration relations from the North Fork Toutle River basin near Mount St. Helens, Washington; annual, seasonal, event, and particle size variations - a preliminary analysis.

    Regression of in-stream turbidity with concurrent sample-based suspended-sediment concentration (SSC) has become an accepted method for producing unit-value time series of inferred SSC (Rasmussen et al., 2009). Turbidity-SSC regression models are increasingly used to generate suspended-sediment records for Pacific Northwest rivers (e.g., Curran et al., 2014; Schenk and Bragg, 2014; Uhrich and Bragg, 2003). Recent work developing turbidity-SSC models for the North Fork Toutle River in Southwest Washington (Uhrich et al., 2014), as well as other studies (Landers and Sturm, 2013, Merten et al., 2014), suggests that models derived from annual or greater datasets may not adequately reflect shorter term changes in turbidity-SSC relations, warranting closer inspection of such relations. In-stream turbidity measurements and suspended-sediment samples have been collected from the North Fork Toutle River since 2010. The study site, U.S. Geological Survey (USGS) streamgage 14240525 near Kid Valley, Washington, is 13 river km downstream of the debris avalanche emplaced by the 1980 eruption of Mount St. Helens (Lipman and Mullineaux, 1981), and 2 river km downstream of the large sediment retention structure (SRS) built from 1987–1989 to mitigate the associated sediment hazard. The debris avalanche extends roughly 25 km down valley from the edifice of the volcano and is the primary source of suspended sediment moving past the streamgage (NF Toutle-SRS). Other significant sources are debris flow events and sand deposits upstream of the SRS, which are periodically remobilized and transported downstream. Also, finer material often is derived from the clay-rich original debris avalanche deposit, while coarser material can derive from areas such as fluvially reworked terraces.

    This study presents an analysis of temperature and precipitation trends and their impact on grape harvests in the Penedès region (NE Spain). It includes analyses of maximum, minimum and mean daily temperatures (for both the growing and ripening seasons) and daily rainfall (for the hydrological year, the growing season and each phenological stage) for three observatories in the immediate area. We analysed a series of factors: beginning and end harvest dates; the day on which a given potential alcoholic degree was reached; and yield for several varieties of grape grown in the area in relation to climatic variables. Maximum temperatures increased at all the observatories, with greater values being recorded in recent years (1996-2009) than in previous decades (1960s-2000s): we observed increases in average growing season temperatures of 0.11°C per year for the period 1996-2009 vs 0.04°C per year for the period 1960-2009 at Vilafranca del Penedès. These temperature changes were due mainly to increases in maximum temperatures and an increase in the incidence of extreme heat (number of days with T > 30°C). Crop evapotranspiration also increased significantly during the same period. The Winkler index also increased, so the study area would correspond to region IV according to that climatic classification. There were no significant trends in annual rainfall but rainfall recorded between bloom and veraison decreased significantly at the three observatories, with the greatest decrease corresponding to the period 1996-2009. The dates on which harvests started and ended showed a continuous advance (of between -0.7 and -1.1 days per year, depending on the variety), which was significantly correlated with the average mean and maximum daily growing season temperatures (up to -7.68 days for 1°C increase). Winegrape yield was influenced by the estimated water deficit (crop evapotranspiration minus precipitation) in the bloom-veraison period; this value increased due to a

    The 12th International Workshop on Desorption Induced by Electronic Transitions (DIET XII) took place from 19-23 April 2009 in Pine Mountain, Georgia, USA. This was the 12th conference in a strong and vibrant series, which dates back to the early 1980s. DIET XII continued the tradition of exceptional interdisciplinary science and focused on the study of desorption and dynamics induced by electronic excitations of surfaces and interfaces. The format involved invited lectures, contributed talks and a poster session on the most recent developments and advances in this area of surface physics. The Workshop International Steering Committee and attendees wish to dedicate DIET XII to the memory of the late Professor Theodore (Ted) Madey. Ted was one of the main pioneers of this field and was one of the primary individuals working to keep this area of science exciting and adventurous. His overall contributions to surface science were countless and his contributions to the DIET field and community were enormous. He is missed and remembered by many friends and colleagues throughout the world. The papers collected in this issue cover many of the highlights of DIET XII. Topics include ultrafast electron transfer at surfaces and interfaces, quantum and spatially resolved mapping of surface dynamics and desorption, photon-, electron- and ion-beam induced processes at complex interfaces, the role of non-thermal desorption in astrochemistry and astrophysics and laser-/ion-based methods of examining soft matter and biological media. Although the workshop attracted many scientists active in the general area of non-thermal surface processes, DIET XII also attracted many younger scientists (i.e., postdoctoral fellows, advanced graduate students, and a select number of advanced undergraduate students). This field has had an impact in a number of areas including nanoscience, device physics, astrophysics, and now biophysics. We believe that this special issue of Journal of Physics

    Twelve 3/4 Angus (Angus) and 12 Wagyu-cross (1/2 Wagyu x 1/2 Angus) (Wagyu) heifers were weaned at 180 d of age and grazed on endophyte-infected tall fescue for 16 mo before entering the feedlot as 2-yr-olds. Twelve 3/4 Angus heifer calves and 12 Wagyu-cross heifer calves from the following year's calf crop were weaned at 142 +/- 4.1 d of age, immediately adjusted to an 80% concentrate diet, and finished as calves. All heifers were fed a common finishing diet until an estimated 50% of their respective group would grade USDA low Prime or better based on ultrasound predictions. Ultrasound measurements of s.c. and i.m. fat depots were recorded at 60-d intervals throughout the finishing period. Heifers finished as calves had higher (P = 0.02) marbling scores at any given fat thickness and gained more efficiently (P < or = 0.01) at any given marbling score than heifers finished as 2-yr-olds. Gain:feed decreased quadratically (P < or = 0.05) as 12th-rib fat thickness increased for Angus and Wagyu heifers. Gain:feed decreased linearly (P < or = 0.01) for Wagyu calves and quadratically (P < or = 0.01) for Angus calves as 12th-rib fat thickness increased. However, these differences in slope were not different (P = 0.34) as a result of breed among heifers finished as calves. Marbling score increased linearly (P < or = 0.01) as 12th-rib fat thickness increased for Angus and Wagyu heifers finished as 2-yrolds or as calves. However, Wagyu heifers, regardless of age at feedlot entry, had a higher marbling score (P < or = 0.05) at any given 12th-rib fat thickness than Angus heifers. Finishing early-weaned heifers as calves as opposed to 2-yr-olds results in i.m. fat deposition during a period of more efficient growth. Additionally, including Wagyu genetics into the breeding of early-weaned heifers finished as calves or as 2-yr-olds results in higher marbling scores at any 12th-rib fat thickness.

    The topic of the behaviour of energetic alpha particles in magnetic fusion confined plasmas is perhaps the ultimate frontier plasma physics issue that needs to be understood in the quest to achieve controlled power from the fusion reaction in magnetically confined plasmas. The partial pressure of alpha particles in a burning plasma will be ~5-10% of the total pressure and under these conditions the alpha particles may be prone to develop instability through Alfvénic interaction. This may lead, even with moderate alpha particle loss, to a burn quench or severe wall damage. Alternatively, benign Alfvénic signals may allow the vital information to control a fusion burn. The significance of this issue has led to extensive international investigations and a biannual meeting that began in Kyiv in 1989, followed by subsequent meetings in Aspenäs (1991), Trieste (1993), Princeton (1995), JET/Abingdon (1997), Naka (1999), Gothenburg (2001), San Diego (2003), Takayama (2005), Kloster Seeon (2007) and Kyiv (2009). The meeting was initially entitled 'Alpha Particles in Fusion Research' and then was changed during the 1997 meeting to 'Energetic Particles in Magnetic Confinement Systems' in appreciation of the need to study the significance of the electron runaway, which can lead to the production of energetic electrons with energies that can even exceed the energy produced by fusion products. This special issue presents some of the mature interesting work that was reported at the 12th IAEA Technical Meeting on Energetic Particles in Magnetic Confinement Systems, which was held in Austin, Texas, USA (7-11 September 2011). This meeting immediately followed a related meeting, the 5th IAEA Technical Meeting on Theory of Plasma Wave Instabilities (5-7 September 2011). The meetings shared one day (7 September 2011) with presentations relevant to both groups.

  3. Rates of Substance Use of American Indian Students in 8th, 10th, and 12th Grades Living on or Near Reservations: Update, 2009–2012

    Objectives Understanding the similarities and differences between substance use rates for American Indian (AI) young people and young people nationally can better inform prevention and treatment efforts. We compared substance use rates for a large sample of AI students living on or near reservations for the years 2009–2012 with national prevalence rates from Monitoring the Future (MTF). Methods We identified and sampled schools on or near AI reservations by region; 1,399 students in sampled schools were administered the American Drug and Alcohol Survey. We computed lifetime, annual, and last-month prevalence measures by grade and compared them with MTF results for the same time period. Results Prevalence rates for AI students were significantly higher than national rates for nearly all substances, especially for 8th graders. Rates of marijuana use were very high, with lifetime use higher than 50% for all grade groups. Other findings of interest included higher binge drinking rates and OxyContin® use for AI students. Conclusions The results from this study demonstrate that adolescent substance use is still a major problem among reservation-based AI adolescent students, especially 8th graders, where prevalence rates were sometimes dramatically higher than MTF rates. Given the high rates of substance use-related problems on reservations, such as academic failure, delinquency, violent criminal behavior, suicidality, and alcohol-related mortality, the costs to members of this population and to society will continue to be much too high until a comprehensive understanding of the root causes of substance use are established.

    Data on psychoactive substance (PAS) consumption among adolescents in the North Center of Morocco are not at all available. Therefore, the current study aimed at investigating the prevalence and the determinants of psychoactive substances use among middle and high school students in this region. A cross-sectional study was conducted from April 2012 to November 2013 in public middle and high schools in the North Central Region of Morocco. An anonymous self-administered questionnaire was used to assess psychoactive substances use among a representative sample of school students from the 7th to the 12th grade, aged 11-23 years, selected by stratified cluster random sampling. Factors associated with psychoactive substance use were identified using multivariate stepwise logistic regression analyses. A total of 3020 school students completed the questionnaires, 53.0 % of which were males. The overall lifetime smoking prevalence was 16.1 %. The lifetime, annual and past month rates of any psychoactive substance use among the study subjects were 9.3, 7.5, and 6.3 % respectively. Cannabis recorded the highest lifetime prevalence of 8.1 %, followed by alcohol 4.3 %, inhalants 1.7 %, psychotropic substances without medical prescription 1.0, cocaine 0.7, heroine 0.3, and amphetamine with only 0.2 %. Psychoactive substance use was associated with males more than females. The risk factors identified by multivariate stepwise logistic regression analyses were being male, studying in secondary school level, smoking tobacco, living with a family member who uses tobacco, and feeling insecure within the family. The prevalence among all school students reported by the current study was comparable to the national prevalence. Efforts to initiate psychoactive substance prevention programs among school students should be made by designing such programs based on the significant factors associated with psychoactive substance use identified in this study.

  11. Racial/ethnic differences in the relationship between parental education and substance use among U.S. 8th-, 10th-, and 12th-grade students: findings from the Monitoring the Future project.

    Secondary school students' rates of substance use vary significantly by race/ethnicity and by their parents' level of education (a proxy for socioeconomic status). The relationship between students' substance use and race/ethnicity is, however, potentially confounded because parental education also differs substantially by race/ethnicity. This report disentangles the confounding by examining White, African American, and Hispanic students separately, showing how parental education relates to cigarette smoking, heavy drinking, and illicit drug use. Data are from the 1999-2008 Monitoring the Future nationally representative in-school surveys of more than 360,000 students in Grades 8, 10, and 12. (a) High proportions of Hispanic students have parents with the lowest level of education, and the relatively low levels of substance use by these students complicates total sample data linking parental education and substance use. (b) There are clear interactions: Compared with White students, substance use rates among African American and Hispanic students are less strongly linked with parental education (and are lower overall). (c) Among White students, 8th and 10th graders show strong negative relations between parental education and substance use, whereas by 12th grade their heavy drinking and marijuana use are not correlated with parental education. Low parental education appears to be much more of a risk factor for White students than for Hispanic or African American students. Therefore, in studies of substance use epidemiology, findings based on predominantly White samples are not equally applicable to other racial/ethnic subgroups. Conversely, the large proportions of minority students in the lowest parental education category can mask or weaken findings that are clearer among White students alone.

  12. Competition between alien annual grasses and native annual plants in the Mojave Desert

    Brooks, Matthew L.

    2000-01-01

    Alien annual grasses in the genera Bromus and Schismus are widespread and abundant in the Mojave Desert, and negative correlations between these aliens and native annual plants suggest that competition may occur between them. Effects of competition were evaluated by thinning alien annual grass seedlings and measuring the responses of native annual plants at three sites in the central, southcentral and southwestern Mojave Desert during 2 y of contrasting plant productivity. Effects ofBromus and Schismus were evaluated separately in the microhabitat where each was most abundant, beneath the north side of creosote bushes (Larrea tridentata) for Bromus and in the open interspace between shrubs for Schismus. Thinning of Bromus and Schismus significantly increased density and biomass of native annuals at all three sites, only during a year of high annual plant productivity and species richness. Effects of thinning were greatest for Amsinckia tesselata and for a group of relatively uncommon native annuals. Thinning also significantly increased the density and biomass of the alien forb, Erodium cicutarium. These results show that alien annual grasses can compete with native annual plants and an alien forb in the Mojave Desert and that effects can vary among years.

    2010-01-01

    A key feature of anticipated 21st century droughts in Southwest North America is the concurrence of elevated temperatures and increased aridity. Instrumental records and paleoclimatic evidence for past prolonged drought in the Southwest that coincide with elevated temperatures can be assessed to provide insights on temperature-drought relations and to develop worst-case scenarios for the future. In particular, during the medieval period, ∼AD 900–1300, the Northern Hemisphere experienced temperatures warmer than all but the most recent decades. Paleoclimatic and model data indicate increased temperatures in western North America of approximately 1 °C over the long-term mean. This was a period of extensive and persistent aridity over western North America. Paleoclimatic evidence suggests drought in the mid-12th century far exceeded the severity, duration, and extent of subsequent droughts. The driest decade of this drought was anomalously warm, though not as warm as the late 20th and early 21st centuries. The convergence of prolonged warming and arid conditions suggests the mid-12th century may serve as a conservative analogue for severe droughts that might occur in the future. The severity, extent, and persistence of the 12th century drought that occurred under natural climate variability, have important implications for water resource management. The causes of past and future drought will not be identical but warm droughts, inferred from paleoclimatic records, demonstrate the plausibility of extensive, severe droughts, provide a long-term perspective on the ongoing drought conditions in the Southwest, and suggest the need for regional sustainability planning for the future.

    Welcome to this special section of the Journal of Micromechanics and Microengineering (JMM). This section, co-edited by myself and by Professor Jeffrey Lang of the Massachusetts Institute of Technology, contains expanded versions of selected papers presented at the Power MEMS meeting held in Atlanta, GA, USA, in December of 2012. Professor Lang and I had the privilege of co-chairing Power MEMS 2012, the 12th International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Applications. The scope of the PowerMEMS series of workshops ranges from basic principles, to materials and fabrication, to devices and systems, to applications. The many applications of power MEMS (microelectromehcanical systems) range from MEMS-enabled energy harvesting, storage, conversion and conditioning, to integrated systems that manage these processes. Why is the power MEMS field growing in importance? Smaller-scale power and power supplies (microwatts to tens of watts) are gaining in prominence due to many factors, including the ubiquity of low power portable electronic equipment and the proliferation of wireless sensor nodes that require extraction of energy from their embedding environment in order to function. MEMS manufacturing methods can be utilized to improve the performance of traditional power supply elements, such as allowing batteries to charge faster or shrinking the physical size of passive elements in small-scale power supplies. MEMS technologies can be used to fabricate energy harvesters that extract energy from an embedding environment to power wireless sensor nodes, in-body medical implants and other devices, in which the harvesters are on the small scales that are appropriately matched to the overall size of these microsystems. MEMS can enable the manufacturing of energy storage elements from nontraditional materials by bringing appropriate structure and surface morphology to these materials as well as fabricating the electrical interfaces

    1987-11-01

    The Yemen Arab Republic, also called North Yemen, is a small republic on the southern tip of the Arabian peninsula facing the Red Sea. Yemen has a temperate interior suitable for agriculture. 8.7 million people of Semetic Arab origin are growing at a rate of 3.1% yearly. The infant mortality rate is 173/1000; the life expectancy is 44 years, and the per capita income is about $550. Yemen was once self-sufficient in food production, exporting fine coffee. Years of civil wars, emigration to Saudi Arabia for work, production of the cash crop "qat" for internal consumption, and the recent drought have contributed to the decline of agriculture. Yemen's economy is maintained by foreign aid from Saudi Arabia, the Soviet Union, China, and the United States. U.S. aid has centered around food, roads and other development projects and primary health care such as immunization and reduction of child mortality.

  18. The impact of inter-annual variability of annual cycle on long-term memory in long historical temperature records

    NASA Astrophysics Data System (ADS)

    Deng, Qimin; Fu, Zuntao

    2017-04-01

    Changes in the estimation of long-term correlation induced by inter-annual variability of annual cycle have been investigated by means of detrended fluctuation analysis (DFA). In a consequence of the intrinsic nonlinearity of the climate system, the annual cycle suffers from both amplitude and phase fluctuations. How does this changing annual cycle affect the fluctuation of temperature anomalies? A recently developed adaptive data analysis tool, the Nonlinear Mode Decomposition (NMD), is used to extract and remove time-varying annual cycle. We compared the differences of the long-term correlation calculated by removing different annual cycle, time-varying and stationary. The study was based on long historical temperature records around the North Atlantic Ocean. The traditional climatology annual cycle which lack characteristic of inter-annual fluctuation would lead to: (1) the estimation of Hurst exponent (2) how to choose scaling range and (3) the goodness of fit. Especially removing steady climatology annual cycle would introduce an artificial crossover around one-year period in the DFA curve. The conclusion is verified by generating deterministic time series through Monte Carlo simulations.

    The total area covered by petroleum rights in the six countries described in this paper increased by more than 17% in 1980 compared to 1979. Joint venture agreements were finalized for 19 blocks over 94,000 km/sup 2/ in the Algerian venture. Although official information is scarce for Algeria and Libya, seismic activity probably increased in 1980 compared to 1979. Exploration drilling activity increased with 121 wildcats drilled compared to 93 during the previous year. This effort led to 40 discoveries, a 34.5% success ratio. Chevron was especially successful in wildcatting, with 6 oil discoveries for 8 wells drilled in the interior basins of Sudan. One Moroccan discovery can be considered as a highlight: the BRPM Meskala 101 well in the Essaouira basin found an apparently large amount of gas in Triassic sandstones. This discovery deserves special attention, since the gas has been found in Triassic pays rather than in the usual Jurassic pays in the Essaouira basin. Oil production in North Africa decreased from about 13.5% in 1980, with about 3,405,000 barrels of oil per day compared to 3,939,500 barrels of oil per day in 1979. When oil output strongly decreased in Algeria (-16.4%) and Libya (-15.6%), Tunisian production peaked at 116,287 barrels of oil per day and Egypt production also peaked at 584,148 barrels of oil per day. Total gas production in 1980 strongly declined from 44%, mostly due to the decline of the Algerian gas production. 8 figures, 40 tables.

    2017-04-01

    In this study, the variations at different time scales such as the annual cycle, the semiannual oscillation (SAO), the ter-annual cycle (about four monthly) and the quasi-biennial oscillation (QBO) in zonal mean GW amplitudes and GW momentum flux (GWMF) have been investigated using satellite observations from 2002-2014 and combining ECMWF high resolution data with the GORGRAT model. The global distribution (patterns) of spectral amplitudes of GW momentum flux in stratosphere and mesosphere (from 30 km to 90 km) show that the annual cycle is the most predominant variation, and then are SAO, ter-annual cycle and QBO. For annual components, two relatively isolated amplitude maxima appear in each hemisphere: a subtropical maximum is associated with convective sources in summer, a mid and high latitude maximum is associated with the polar vortex in winter. In the subtropics, GWs propagate upward obliquely to the higher latitudes. The winter maximum in the southern hemisphere has larger momentum flux than that one in the northern hemisphere. While on the SH the phase (i.e. time corresponding to the maximum GWMF) continuously descends with the maximum in July in the upper mesosphere and in September in the lower stratosphere, on the northern hemisphere, the phase has no visible altitude dependence with a maximum in December. For semiannual variations, in the MLT (70-80 km) region, there is an obvious enhancement of spectral amplitude at equatorial latitudes which relate to the dissipation of convectively forced GWs. The SAO in absolute momentum flux and the annual cycle in zonal momentum flux indicated that the variations at mid-latitudes (about from 30°-40°) are not a SAO signals but rather an annual cycle when the direction of GWMF is considered. The ter-annual cycle may be related to the duration of active convection in subtropical latitudes (from June to Sep. in north hemisphere) Indications for QBO are found latitude extension to mid-latitudes in stratosphere of

    1993-03-01

    Winter snowpack was investigated to determine spatial and temporal climate variability in a five-state region (Colorado, Idaho, Montana, Utah, and Wyoming) in the northern Rocky Mountains, covering the period 1951-1985. Annual 1 April snowpack (SN) measurements were selected for analyses. Three basic and persistent patterns of annual SN values surfaced: years with a consistent anomaly over the entire region (wet or dry); years with a distinct north-to-south gradient; and average years. Nearly 90% of the nonaverage annual SN patterns were explained by the frequency of seven 500-mb winter synoptic patterns. The wet-north-dry-south gradient SN patterns occurred only before 1974, and the dry-north-wet-south gradient southern areas of the five-state region are due to periods when one of the two north-to-south gradient SN patterns occurred and are explained by the changes in the frequency of synoptic patterns. 20 refs., 19 figs., 6 tabs.

  16. North American Gross Primary Productivity: Regional Characterization and Interannual Variability

    NASA Astrophysics Data System (ADS)

    Baker, I. T.; Denning, A.; Stockli, R.

    2009-12-01

    Seasonality and variability in North American photosynthetic activity are investigated. Using the Simple Biosphere Model (SiB) we simulate 24 years (1983-2006) and evaluate regional and seasonal contribution to annual mean Gross Primary Productivity (GPP) as well as its interannual variability. The largest productivity occurs in tropical Mexico, the southeast U.S. and small areas in the Pacific Northwest. Annual variability is largest in tropical Mexico, the desert Southwest, and the Midwestern corridor that separates the eastern forests from the intermountain west. We find that several areas (Midwest, Northeast, SouthWest, Boreal Canada) have an elevated contribution to interannual variability when compared to other regions, but no single region or season consistently determines continental annual GPP anomaly on an annual basis. GPP variability in NA is highly heterogeneous in space and time. We find that GPP variability is generally dependent upon soil moisture in low- and mid-latitudes, and on temperature in the north. Soil moisture is a better metric than raw precipitation as it integrates precipitation events temporally. EOF analysis shows no significance on an annual basis, but a band from the central plains through New England shows a coherent signal for springtime GPP anomalies. As the springtime anomaly is the largest contributor to the annual GPP variability in almost half of the years simulated (11 of 24), we can posit that this region has significant influence over annual North American GPP variability. However, when regressed against climate modes such as El Nino Southern Oscillation (ENSO), Arctic Oscillation (AO) or Pacific-North America (PNA) patterns, we find that no climate mode can be associated with variability over the entire region highlighted by the EOF analysis. Furthermore, we find that while a general response to temperature is seen (warmer spring implies longer growing season implies anomalous GPP uptake of carbon), in some regions the

    From April 2007, all centres providing renal replacement therapy in England were asked to provide additional data on patients with Methicillin Resistant Staphylococcus aureus (MRSA) bacteraemia using a secure web based system established to capture data for the mandatory surveillance of MRSA bacteremia. From April 2008 until March 2009 171 discrete episodes of MRSA bacteraemia were identified from the Health Protection Agency database as being potentially associated with patients in established renal failure (ERF) requiring dialysis. Of 171 records, 18 records were rejected by renal centres as not being associated with patients on dialysis or as being duplicates of other records. Following data validation by centres, 139 patients had vascular access documented (no episodes of bacteraemia were recorded amongst patients receiving peritoneal dialysis). Of these patients, 30.2% were utilising an arteriovenous fistula or graft and 69.8% were dialysing on a nontunnelled or tunnelled venous catheter. Two of the patients on arteriovenous fistulae had used venous catheters in the prior 28 days. Eleven patients had more than one episode in the year and accounted for 30 (20%) of the episodes of MRSA bacteraemia. Overall there was a reduction of 22% in episodes from the previous year. The median centre-specific rate of MRSA bacteraemia was 0.64 (range 0-3.49) episodes per 100 haemodialysis patients per year, and 0.55 (range 0-2.89) episodes per 100 dialysis (haemodialysis and peritoneal dialysis combined) patients per year. The rate of MRSA bacteraemia in patients requiring long term dialysis continues to fall within the prevalent dialysis population in England, but there is still marked variation in centrespecific rates.
