    High-molecular-weight kininogen (HK) plays an important role in the assembly of the plasma kallikrein-kinin system. While the human genome contains a single copy of the kininogen gene, 3 copies exist in the rat (1 encoding K-kininogen and 2 encoding T-kininogen). Here, we confirm that the mouse genome contains 2 homologous kininogen genes, mKng1 and mKng2, and demonstrate that these genes are expressed in a tissue-specific manner. To determine the roles of these genes in murine development and physiology, we disrupted mKng1, which is expressed primarily in the liver. mKng1−/− mice were viable, but lacked plasma HK and low-molecular-weight kininogen (LK), as well as ΔmHK-D5, a novel kininogen isoform that lacks kininogen domain 5. Moreover, despite normal tail vein bleeding times, mKng1−/− mice displayed a significantly prolonged time to carotid artery occlusion following Rose Bengal administration and laser-induced arterial injury. These results suggest that a single gene, mKng1, is responsible for production of plasma kininogen, and that plasma HK contributes to induced arterial thrombosis in mice. PMID:18000168

    Norman Garmezy, a pioneer in research on risk and resilience, died in Nashville, Tennessee, on November 21, 2009, at the age of 91. He was a legendary mentor as well as an eminent scientist in clinical psychology. Norm was born on June 18, 1918, in New York City and grew up in the Bronx in a Jewish neighborhood where educational attainment was highly valued. The scientific study of resilience as conceived by Norman Garmezy, his peers, and students has transformed the science and practice of multiple disciplines, from the molecular level to the global ecosystem, infusing a strength-based and recovery-oriented approach into psychology, education, social work, and psychiatry. Current research on resilience ranges from studies of plasticity in brain development to effective planning for resilience in the context of disaster. Norm's influential ideas and research earned him international acclaim and many honors for lifetime achievements in science. Throughout his career, Norm held many leadership roles. Throughout his life, Norm spoke with great love about his wife of 63 years, Edie Garmezy (who died just months before him in 2009), and their children. In addition to his work and his family, Norm had three abiding passions-theater, movies, and politics. During the last two decades of his life, Norm and those who loved him endured his long decline from Alzheimer's, which slowly stole his brilliant mind and hilarious sense of humor. Nonetheless, the incredible spirit and humanity of this giant scholar continued to shine through this terrible disease. To the end of his life, Norm's face would light up with a smile as he greeted the people he loved, and he would often exclaim, "Wonderful!" Norman Garmezy was a remarkable person and scholar who left an extraordinary legacy of love and work to inspire future generations in their efforts to understand and promote the human capacity for competence and resilience.

A plasma is, after all, a strongly correlated object, and there is nothing so special about it!" "Yes, Norman, you are so correct! A statistical system consisting of mutually non-interacting and thus uncorrelated particles may be an "ideal-gas" system from a physics teacher's pedagogical point of view, but real systems do consist of mutually interacting and thus strongly correlated particles; a plasma is definitely one of them.Here, in the memory of Professor Rostoker's outstanding contributions to strongly correlated plasmas for the past 60 years, we wish to survey on "Scattering of Electromagnetic Waves by a Strongly Correlated Plasma" and "Multi-particle Correlation, Equations of State, and Phase Diagrams" in what follows.

    2015-01-01

    BACKGROUND: Henry Norman Bethune is one of the most exciting and incredible surgeons that Canada has ever produced. Indeed, he is often characterized as one of the world’s best-known surgeons. He was an innovator and his scientific contributions have stood the test of time. In Canada, he will forever be remembered as a social activist committed to the welfare of the poor and to the reform of the health care system. In the People’s Republic of China, he is idolized and remains the only foreigner to ever become a national hero. OBJECTIVE: To detail the numerous and significant achievements of Henry Norman Bethune in the field of thoracic surgery and as a social activist and describe his heroic war-time actions on the battlefields of both Spain and China. METHOD: Information was gathered through the reading of the numerous publications written about the life and work of Bethune, interviews with knowledgeable people from Canadian and Chinese universities, analysis of Bethune’s own publications, and extensive experience of one of the authors in China. RESULTS: In the social sense, Henry Norman Bethune had a difficult personality, but he was deeply caring about the plight of his patients, especially the poor. As a thoracic surgeon, he could be ingenious, thoughtful and effective but he could also be abrasive, restless and temperamental. His scientific contributions were sound and, at the time, gained worldwide attention. As an activist, he led a crusade to reform the Canadian health care system, demanding free health care for all. His outstanding work during the Spanish Civil War, where he organized the first ever mobile blood transfusion unit, and during the Sino-Japanese war, where he was totally committed to the welfare of both soldiers and civilian population, were deliberate acts of resistance against Fascist onslaught and enthusiasm for the Communist cause. CONCLUSIONS: Henry Norman Bethune was unconventional and a revolutionary, but he was brilliant. He will

    2014-10-01

    Compilation of modern and historical length change records for Franz Josef and Fox Glaciers demonstrates that these glaciers have lost ~ 3 km in length and at least 3-4 km2 in area since the 1800s, with the greatest overall loss occurring between 1934 and 1983. Within this dramatic and ongoing retreat, both glaciers have experienced periods of re-advance. The record from Franz Josef Glacier is the most detailed, and shows major advances from 1946 to 1951 (340 m), 1965-1967 (400 m), 1983-1999 (1420 m) and 2004-2008 (280 m). At Fox Glacier the record is similar, with advances recorded during 1964-1968 (60 m), 1985-1999 (710 m) and 2004-2008 (290 m). Apart from the latest advance event, the magnitude of advance has been greater at Franz Josef Glacier, suggesting a higher length sensitivity. Analysis of the relationship between glacier length and a reconstructed annual equilibrium line altitude (ELA) record shows that the glaciers react very quickly to ELA variations - with the greatest correlation at 3-4 years' lag. The present (2014) retreat is the fastest retreat in the records of both glaciers. While decadal length fluctuations have been linked to hemispheric ocean-atmosphere variability, the overall reduction in length is a clear sign of twentieth century warming. However, documenting glacier length changes can be challenging; especially when increased surface debris-cover makes identification of the 'true' terminus a convoluted process.

    Joseph Norman Lockyer was born in 1836 in Rugby, where his father was a surgeon-apothecary and a leading member of the Literary and Scientific Institution. In the 1840s the family moved to Leicester, where his father became a manufacturer of matches. After his mother's death, he lived with an uncle and attended school in Kenilworth. His main interests then were classical and modern languages, which he taught in a Somerset school before going to Switzerland in 1856-57. On his return, the patronage of Lord Leigh of Stoneleigh helped him to become a clerk in the War Office. He developed an interest in astronomy that led to his election as a Fellow of the Royal Society, and to the editorship of the science journal Nature.

    Josef Koncz (1916-1988) was until given emeritus status in 1982 director of the Department of Cardiothoracic and Vascular Surgery, which was specifically founded for him in Goettingen, Germany. By the fusion of three different surgical branches the University hospital of Goettingen took over the role of a pacemaker and initiated a standard in the development of this new specialty in Germany. The scientific and clinical work done by the Department of Cardiothoracic and Vascular Surgery was shaped by the personality of the surgeon and scientist Josef Koncz. He was a successful surgeon and innovative pioneer in one person. Already in 1956, he started open-heart surgery and proceeded this technique in an impressing series. In 1965 he was the first in Germany who operated upon the transposition of the great vessels by Mustard's method and developed together with his long-standing assistant, Huschang Rastan, an operation technique to extend the left-ventricular outflow tract combined with tunnel-shaped subvalvular aortic valve stenosis. Another essential element of his work is related to the establishment of the Cardiothoracic and Vascular Surgery as an independent specialty, ending in the foundation of the German Society for Thoracic and Cardiovascular Surgery in 1971.

  18. Recharge processes in an alluvial aquifer riparian zone, Norman Landfill, Norman, Oklahoma, 1998-2000

    Analyses of stable isotope profiles (d2H and d18O) in the saturated zone, combined with water-table fluctuations, gave a comprehensive picture of recharge processes in an alluvial aquifer riparian zone. At the Norman Landfill U.S. Geological Survey Toxic Substances Hydrology research site in Norman, Oklahoma, recharge to the aquifer appears to drive biodegradation, contributing fresh supplies of electron acceptors for the attenuation of leachate compounds from the landfill. Quantifying recharge is a first step in studying this process in detail. Both chemical and physical methods were used to estimate recharge. Chemical methods included measuring the increase in recharge water in the saturated zone, as defined by isotopic signature, specific conductance or chloride measurements; and infiltration rate estimates using storm event isotopic signatures. Physical methods included measurement of water-table rise after individual rain events and on an approximately monthly time scale. Evapotranspiration rates were estimated using diurnal watertable fluctuations; outflux of water from the alluvial aquifer during the growing season had a large effect on net recharge at the site. Evaporation and methanogenesis gave unique isotopic signatures to different sources of water at the site, allowing the distinction of recharge using the offset of the isotopic signature from the local meteoric water line. The downward movement of water from large, isotopically depleted rain events in the saturated zone yielded recharge rate estimates (2.2 - 3.3 mm/day), and rates also were determined by observing changes in thickness of the layer of infiltrated recharge water at the top of the saturated zone (1.5 - 1.6 mm/day). Recharge measured over 2 years (1998-2000) in two locations at the site averaged 37 percent of rainfall, however, part of this water had only a short residence time in the aquifer. Isotopes showed recharge water entering the ground-water system in winter and spring, then being

    2014-01-01

    The remote Franz Josef Land (FJL) Archipelago is the most northerly land in Eurasia and its fish fauna, particularly in nearshore habitats, has been poorly studied. An interdisciplinary expedition to FJL in summer 2013 used scuba, seines, and plankton nets to comprehensively study the nearshore fish fauna of the archipelago. We present some of the first underwater images for many of these species in their natural habitats. In addition, deep water drop cameras were deployed between 32 and 392 m to document the fish fauna and their associated habitats at deeper depths. Due to its high latitude (79°–82°N), extensive ice cover, and low water temperatures (<0 °C much of the year), the fish diversity at FJL is low compared to other areas of the Barents Sea. Sixteen species of fishes from seven families were documented on the expedition, including two species previously unknown to the region. One Greenland shark, Somniosus microcephalus (Somniosidae), ca. 2 m in length, was recorded by drop camera near Hayes Island at 211 m, and Esipov’s pout, Gymnelus esipovi (Zoarcidae), was collected at Wilton Island at 15 m in a kelp forest. Including the tape-body pout, Gymnelus taeniatus, described earlier from the sub-littoral zone of Kuhn Island, 17 fish species are now known from FJL’s nearshore waters. Species endemic to the Arctic accounted for 75% of the nearshore species observed, followed by species with wider ranges. A total of 43 species from 15 families are known from FJL with the majority of the records from offshore trawl surveys between 110 and 620 m. Resident species have mainly high Arctic distributions, while transient species visit the archipelago to feed (e.g., Greenland shark), and others are brought by currents as larvae and later migrate to spawn grounds in the south (e.g., Atlantic cod Gadus morhua, Capelin Mallotus villosus, Beaked redfish Sebastes mentella). Another species group includes warmer-water fishes that are rare waifs (e.g., Glacier

    Barry Dawson is just right for th e first Norman L. Bowen Award in Volcanology, Geochemistry, and Petrology. Like Norman L. Bowen, he has the inspiration to combine ideas from different disciplines to obtain a higher synthesis. Consider his brilliant talk of yesterday morning (Eos 69, p. 502, abstract V11C-06, Veined and metasomatised upper mantle beneath the Eastern African Rift: Evidence from N. Tanzania xenoliths). Barry rapidly reviewed the tectonic setting of east Africa, showed some nice photographs of the volcanic cones of Pello and Oldoinyo Lengai, focused on the upper-mantle xenoliths in scoria at Pello, moved in on the microscopy and mineral chemistry of the metasomatic veins in the peridotites, snowed how the lower density of a metasomatized peridotite would fit the middle of a geophysical profile from seismic surveys, and brought off a grand finale in which the Kenya dome was interpreted to result from inflation related to metasomatization of underlying peridotite. Undoubtedly, this will lead to many further studies of doming adjacent to rift systems around the world.

    1984-01-01

    Norman Wells crude oil was fractionated by sequential alumina and silicic acid column chromatography methods. The resulting nitrogen-rich fraction was analyzed by gas chromatography-mass spectrometry and showed 26 alkyl (C1 to C5) carbazoles to be the predominant compounds. An oil-degrading mixed bacterial culture was enriched on carbazole to enhance its ability to degrade nitrogen heterocycles. This culture was used to inoculate a series of flasks of mineral medium and Norman Wells crude oil. Residual oil was recovered from these cultures after incubation at 25°C for various times. The nitrogen-rich fraction was analyzed by capillary gas chromatography, using a nitrogen-specific detector. Most of the C1-, C2-, and C3- carbazoles and one of the C4-isomers were degraded within 8 days. No further degradation occurred when incubation was extended to 28 days. The general order of susceptibility of the isomers to biodegradation was C1 > C2 > C3 > C4. The carbazole-enriched culture was still able to degrade n-alkanes, isoprenoids, aromatic hydrocarbons, and sulfur heterocycles in the crude soil. PMID:16346524

    The temporal variability observed in redox sensitive species in groundwater can be attributed to coupled hydrological, geochemical, and microbial processes. These controlling processes are typically nonstationary, and distributed across various time scales. Therefore, the purpose of this study is to investigate biogeochemical data sets from a municipal landfill site to identify the dominant modes of variation and determine the physical controls that become significant at different time scales. Data on hydraulic head, specific conductance, δ2H, chloride, sulfate, nitrate, and nonvolatile dissolved organic carbon were collected between 1998 and 2000 at three wells at the Norman Landfill site in Norman, OK. Wavelet analysis on this geochemical data set indicates that variations in concentrations of reactive and conservative solutes are strongly coupled to hydrologic variability (water table elevation and precipitation) at 8 month scales, and to individual eco-hydrogeologic framework (such as seasonality of vegetation, surface-groundwater dynamics) at 16 month scales. Apart from hydrologic variations, temporal variability in sulfate concentrations can be associated with different sources (FeS cycling, recharge events) and sinks (uptake by vegetation) depending on the well location and proximity to the leachate plume. Results suggest that nitrate concentrations show multiscale behavior across temporal scales for different well locations, and dominant variability in dissolved organic carbon for a closed municipal landfill can be larger than 2 years due to its decomposition and changing content. A conceptual framework that explains the variability in chemical concentrations at different time scales as a function of hydrologic processes, site-specific interactions, and/or coupled biogeochemical effects is also presented.

    A corrected radiocarbon age of 11,050 [+-] 14 years before present for an advance of the Franz Josef Glacier to the Waiho Loop terminal moraine on the western flank of New Zealand's Southern Alps shows that glacier advance on a South Pacific island was synchronous with initiation of the Younger Dryas in the North Atlantic region. Hence, cooling at the beginning of the Younger Dryas probably reflects global rather than regional forcing. The source for Younger Dryas climatic cooling may thus lie in the atmosphere rather than in a North Atlantic thermohaline switch. 36 refs., 2 figs., 1 tab.

    Conventional field-reversed configurations (FRC) face notable stability and confinement concerns, which can be ameliorated by introducing and maintaining a significant fast ion population in the system. This is the conjecture first introduced by Norman Rostoker multiple decades ago and adopted as the central design tenet in Tri Alpha Energy's advanced beam driven FRC concept. In fact, studying the physics of such neutral beam (NB) driven FRCs over the past decade, considerable improvements were made in confinement and stability. Next to NB injection, the addition of axially streaming plasma guns, magnetic end plugs, as well as advanced surface conditioning lead to dramatic reductions in turbulence driven losses and greatly improved stability. In turn, fast ion confinement improved significantly and allowed for the build-up of a dominant fast particle population. This recently led to the breakthrough of sustaining an advanced beam driven FRC, thereby demonstrating successful maintenance of trapped magnetic flux, plasma dimensions and total pressure inventory for times much longer than all characteristic system time scales and only limited by hardware and electric supply constraints.

  9. Spontaneous "cures": Norman Reider's forgotten paper, part II.

    PubMed

    Boesky, Dale

    2014-04-01

    Part I of this paper combined an introduction to Norman Reider's original 1955 paper with a republication of the paper itself. Part II is a discussion of the complexities of a comparison of past and present psychoanalytic literature. The concept of enactment is proposed as one of many possible alternative views in considering Reider's notion of spontaneous "cures." A careful consideration of these spontaneous cures within the ordinary ups and downs of any psychoanalytic treatment sheds important light on our continuing confusion about how we define the term cure, and therefore about the nature of change during psychoanalytic treatment. This alternative perspective is only one of many plausible ones for present-day readers. The purpose of this republication is not to propose an explanation for "what really happened" with Reider and his patients; rather, it is to reconsider the fallacy of evaluating his paper outside its historical context and thereby failing to appreciate his courage in presenting what at the time were radical views. Questions about the complexity and confusion regarding cure and change require reexamination of the neglect of epistemology on the part of psychoanalysis in prolonging the confusion about distinguishing psychotherapy and psychoanalysis.

Holter was elaboration of the method of long-term ECG monitoring of freely active patients--the method which was later named Holter Monitoring (HM). The article also contains data of first clinical trials of HM systems and stresses contribution of Holter team-mates and colleagues (B. Del Mar, G. Kennedy, S. Stern and others) in their conduct. It shows technical and ideological evolution of HM systems from large apparatuses weighting 40 kg to modern portable devices capable of collecting, storing and processing huge amounts of information, transmitting it over internet to any distance. Nontriviality and serendipity of N. Holter's approach to obtaining novel unpredictable knowledge allowed him to realize his numerous talents and abilities. PMID:26050493

    The United States is planning manned lunar and interplanetary missions in the coming years. Shielding from cosmic rays is a critical aspect of manned spaceflight. These ventures will present exposure issues involving the interplanetary Galactic Cosmic Ray (GCR) environment. GCRs are comprised primarily of protons (approx.84.5%) and alpha-particles (approx.14.7%), while the remainder is comprised of massive, highly energetic nuclei. The National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) has commissioned a joint study with Los Alamos National Laboratory (LANL) to investigate the interaction of the GCR environment with humans using high-fidelity, state-of-the-art computer simulations. The simulations involve shielding and dose calculations in order to assess radiation effects in various organs. The simulations are being conducted using high-resolution voxel-phantom models and the MCNPX[1] Monte Carlo radiation-transport code. Recent advances in MCNPX physics packages now enable simulated transport over 2200 types of ions of widely varying energies in large, intricate geometries. We report here initial results obtained using a GCR spectrum and a NORMAN[3] phantom.

  12. Spatial variation in hydraulic conductivity determined by slug tests in the Canadian River alluvium near the Norman Landfill, Norman, Oklahoma

    1998-01-01

    Slug tests were used to characterize hydraulic conductivity variations at a spatial scale on the order of meters in the alluvial aquifer downgradient of the Norman Landfill. Forty hydraulic conductivity measurements were made, most along a 215-meter flow path transect. Measured hydraulic conductivity, excluding clayey layers, ranged from 8.4 ? 10-7 to 2.8 ? 10-4 meters per second, with a median value of 6.6 ? 10-5 meters per second. The hydraulic conductivity measurements yield a preliminary concept of the permeability structure of the aquifer along this transect. A low hydraulic conductivity silt-clay layer at about 4 meters below the water table and a high hydraulic conductivity layer at the base of the aquifer appear to have the most potential to affect contaminant transport. Specific conductance measurements show the leachate plume along this transect becomes attenuated between 150 and 200 meters downgradient of the landfill, except at the base of the aquifer, where it extends at least 225 meters downgradient of the landfill.

  13. Norman Rockwell's "Man's First Step On The Moon"

    Rockwell's painting, which appeared in the January 10, 1967 issue of Look magazine, is perhaps the most famous ever done of an astronaut's first step on the Moon. But it has a number of astronomical misconceptions, many of which are apparent to sharp-eyed introductory astronomy students: the size of the Earth in the lunar sky is too large compared to the Big Dipper, the orbiting Command Service Module is illuminated from a different direction than the Earth is, and the lighting on the lunar surface is also inconsistent, among other errors. This raises the question: How could Rockwell, a notoriously meticulous illustrator, have apparently been so careless? It turns out that Rockwell was anything but careless, but rather was typically obsessive about every detail in the painting. He was in constant communication with experts, even traveling to Huston to meet with NASA officials. He went so far as to enlist the help of space artist Pierre Mion, who ended up doing part of the painting, one of only two known collaborations between Rockwell and another artist. When the Look article was published, readers responded with praise but also criticism about the technical errors that still slipped through, to Rockwell's great frustration. The most important part of the painting, however, is accurate and compelling: the astronaut is shown stepping off the LM exactly as Neil Armstrong would do over two years later. The astronaut's boot covers part of the shadow that it casts. Does the shadow run all the way to the heel, or is the boot poised just above the lunar surface? Has the artist captured the instant after, or, perhaps, the instant before, humanity's first contact with another world? I am grateful to the curators at the Norman Rockwell Museum Archives for their assistance.

    Leachate from municipal landfills can create groundwater contaminant plumes that may last for decades to centuries. The fate of reactive contaminants in leachate-affected aquifers depends on the sustainability of biogeochemical processes affecting contaminant transport. Temporal variations in the configuration of redox zones downgradient from the Norman Landfill were studied for more than a decade. The leachate plume contained elevated concentrations of nonvolatile dissolved organic carbon (NVDOC) (up to 300 mg/L), methane (16 mg/L), ammonium (650 mg/L as N), iron (23 mg/L), chloride (1030 mg/L), and bicarbonate (4270 mg/L). Chemical and isotopic investigations along a 2D plume transect revealed consumption of solid and aqueous electron acceptors in the aquifer, depleting the natural attenuation capacity. Despite the relative recalcitrance of NVDOC to biodegradation, the center of the plume was depleted in sulfate, which reduces the long-term oxidation capacity of the leachate-affected aquifer. Ammonium and methane were attenuated in the aquifer relative to chloride by different processes: ammonium transport was retarded mainly by physical interaction with aquifer solids, whereas the methane plume was truncated largely by oxidation. Studies near plume boundaries revealed temporal variability in constituent concentrations related in part to hydrologic changes at various time scales. The upper boundary of the plume was a particularly active location where redox reactions responded to recharge events and seasonal water-table fluctuations. Accurately describing the biogeochemical processes that affect the transport of contaminants in this landfill-leachate-affected aquifer required understanding the aquifer's geologic and hydrodynamic framework.

  16. Wind influence on sea ice transport through the Svalbard - Franz-Josef Land gate

    Arctic sea ice has declined substantially in all months over the last few decades, but mostly during summer. In contrast, sea ice in the Barents Sea has experienced the largest winter retreat in the Arctic region. Barents Sea ice experiences high inter-annual variability and is influenced by factors such as Atlantic inflow, regional atmospheric circulation, and ice import from the Arctic Ocean. The wind's influence on sea ice motion through the Svalbard - Franz-Josef Land gate, connecting the Barents Sea and Arctic Ocean, was investigated using drifting buoys, passive microwave derived ice drift, weather station observations, reanalysis, and model simulations. Wind forcing of sea ice near Svalbard was analyzed using sea ice buoy drift and observed winds from Hopen island from March to May 2006. A linear relationship of the form V ice = 0.0244V wind + 0.3681 [ms-1] was found between wind speed and ice drift using the free drift assumption. Meridional wind driven ice drift through the Svalbard - Franz-Josef Land gate was investigated using passive microwave satellite data and reanalysis pressure data (1979 to 2011), from which geostrophic wind was calculated. This resulted in a linear relationship of V ice = 0.0021V g - 0.002 [ms-1]. The relationship between wind speed and ice drift was found to be stronger on shorter time scales (hourly/daily) than longer time scales (monthly). Furthermore, the wind had greater influence on sea ice drift when ice cover was thinner, as was the case near Svalbard. Analysis demonstrated that, on average, present ice import from the Arctic Ocean to the Barents Sea through the Svalbard - Franz-Josef Land gate is small. Sea ice drifts faster on the eastern side of the gate compared to the west. However, large ice transport events do occur in winter, given specific atmospheric circulation conditions. Quantification of how effective wind forcing is for ice drift in this region is important for understanding the year-to-year variability, and

  17. Late-Quaternary exhumation rates constrained by OSL thermochronometry at the Franz Josef Glacier, New Zealand

    The Southern Alps of New Zealand are often cited as the primary example of a mountain range that has reached exhumation and topographic steady state, especially on the West Coast where exhumation rates reach up to about 10 mm/yr. However, cyclic climatic changes, throughout the Quaternary period have meant that the Alps cycled between being completely glaciated and ice free. The impact that such glacial cycles may have had on the spatial variability of erosion rates remains poorly constrained. Here we use Optically Stimulated Luminescence (OSL) as a very low temperature thermochronometer to constrain rock cooling histories at 10-100 kyr timescales on samples collected near the Franz Josef glacier. OSL-thermochronometry is based on the amount of electrons accumulated in the lattice defects of natural minerals such as quartz or feldspar, due to the competing effects of charge trapping due to the natural radioactivity within the rock and charge detrapping due to thermal loss during rock exhumation towards the surface. We collected 9 samples along the Waiho valley (crossing the Alpine Fault) and the Franz Josef glacier to quantify late-Quaternary exhumation rates and their potential spatial variations. Bedrock samples have been crushed to extract the light-safe rock interiors which have then been processed to isolate potassium-rich feldspars (K-feldspars). We used the Infra-Red Stimulated Luminescence at 50°C (IRSL50) protocol, including the measurement of the natural IRSL50 trapped charge population and the laboratory characterization of sample-specific thermal and athermal kinetic parameters. Once measured, the luminescence signal can be inverted into cooling histories. We also explored the potential of the recently developed multi-OSL-thermochronometer (King et al., accepted) to better constrain the cooling path. Our first OSL measurements show that samples are not in saturation and thus contain useful thermochronometric information over the last ~100 kyr. Inverse

  18. New Paleomagnetic Data for the Franz Josef Land Archipelago and their Tectonic Consequences

    2014-12-01

    On the base of field work on the Franz Josef Land archipelago (FJL) in 2010 and 2011 the new paleomagnetic data are obtained from the Jurassic-Early Cretaceous magmatic complexes. Main focus of this work was concentrated on the Early-Jurassic basalts widely represented on the Hooker island [1]. Together with the previous data [2] statistically reasonable paleomagnetic pole for the age boundary of 190 million years for the FJL is received (PLat.=62.4; PLon.=140.2; dp/dm=5.5/5.0; N=13). Paleomagnetic data allow to assume that the position of the FJL relative to the Europe in the Early Jurassic significantly differs from the present one. But to the Early Cretaceous it reached relative position very close to the presently observed [2]. We suggest that at least during Early-Middle Jurassic there was rifting processes between the North Barentz terrane (FJL and (may be) Svalbard) and the other part of the European tectonic domain. This rift was accompanied by shifting of the FLJ to the north-eastward on about 500 km. Also obtained paleomagnetic data agree with a hypothesis assuming that the FJL was passing over the Icelandic-Siberian hot spot during Jurassic-Cretaceous time: main paleolatitudes correspond to the Island's present latitude and the paleolatitude of the Siberian trapps. Paleomagnetic study of FJL has a reconnaissance character and cannot lead to any ultimate deductions as the data is obviously not enough. And further work on the basaltic covers of the archipelago seems to be very promising. Research was supported by grant RFBR 13-05-00177. 1. Karyakin Yu.V., Shipilov E.V.

    A model of mass balance is constructed for the Franz Josef Glacier on the west coast of New Zealand. It uses daily data from a nearby, but short-record climate station. The model is extended back to 1913 by creating hybrid climate data from a long-record, but more distant, climate station. Its monthly data provide long-term temperature and precipitation trends, and daily fluctuations are simulated using a stochastic approach that is tuned to the characteristics of the short-record station. The glacier model provides estimates of equilibrium-line altitudes which are in reasonable agreement with those observed, and variations of cumulative mass balance that correspond with patterns of advance and retreat of the glacier terminus.

  2. Glacier speed-up events and water inputs on the lower Franz Josef Glacier, New Zealand

    A glacier speed-up event occurs when a water input exceeds the capacity of the subglacial drainage system, and the subglacial water pressure increases. Several studies have suggested that glacier speed-up events do not affect overall glacier motion, as high ice-flow velocities during the event are offset by lower ice-flow velocities after the event due to a more efficient subglacial drainage system. In this study, we combine in-situ velocity measurements with a full Stokes glacier flowline model to explore the temporal and spatial variability in glacier flow on the lower Franz Josef Glacier, Southern Alps, New Zealand. Significant volumes of water enter the Franz Josef Glacier throughout the year due to high rainfall rates and year-round ablation. As a result, we infer that the subglacial drainage system is generally well-developed. In late summer (March) 2011, measured ice-flow velocities increased by up to 75% above background values because of rain events and by up to 32% above background values because of diurnal melt cycles. The observed speed-up events occurred at all survey locations within 4 ± 1 hours after the peak water input. We use a flowline model to show that a spatially-uniform subglacial water pressure, which increased during periods of heavy rain and glacier melt, can reproduce the measured ice-flow velocities across the lower glacier. From our results, we suggest that the variability in water inputs, rather than the mean water input to the system, is the primary driver in glacier speed-up events. If this is the case and the variability in water inputs is maintained, then glacier speed-up events can occur even if the subglacial drainage system is well-developed.

    In 2000, the U.S. Environmental Protection Agency (EPA) reviewed the arsenic drinking water standard for public water supplies. Considering the available research and statistics on the health effects of arsenic ingestion, the EPA reduced the Maximum Contaminant Level (MCL) for public drinking water from 50 micrograms per liter (?g/L) to 10 ?g/L (U.S. Environmental Protection Agency, 2001a). As a result of the more stringent standard, the EPA estimates that about 3,000 public water providers across the United States must take action to meet the new standard before it becomes effective on January 23, 2006 (U.S. Environmental Protection Agency, 2001b). The City of Norman (City) is one of several Oklahoma municipalities affected by the new arsenic standard. About 20 percent of Norman?s water is supplied by wells completed in the Central Oklahoma (Garber-Wellington) aquifer; the rest is supplied by Lake Thunderbird (fig. 1) or purchased from Oklahoma City. The Norman well field is composed of 24 active wells, and water produced from about half of the wells will not be in compliance with the new MCL (figs. 2 and 3). Chemical treatment of water with elevated arsenic is possible, but it is generally cost prohibitive. Another costly solution is simply to abandon the high-arsenic wells and replace them with new wells in low-arsenic areas. In the next phase of well construction beginning in 2005, the City plans to construct as many as 30 new wells in northeast Norman (Bryan Mitchell, City of Norman, oral commun., 2005). The new wells will replace production lost to the new arsenic standard and add new production to keep pace with rapidly growing consumer demand. Well modification to exclude arsenic-bearing water from existing wells is a more cost-effective solution, but it requires a great deal of knowledge about local aquifer properties and individual well dynamics to decide which wells are good candidates for modification. With the goal of determining if well modification

    2003-04-01

    The Little Ice Age (LIA) chronology of the Franz Josef Glacier (FJG), New Zealand, was reassessed due to previous uncertainty surrounding the timing of its maximum extent, eg. 1450 (Burrows 1990), 1600 (Wardle 1973) or 1750 AD (Lawrence and Lawrence 1965). Tree age-size relationships based on data from 75 ring counts and diameters collected from southern rata (Metrosideros umbellata) and kamahi (Weinmannia racemosa) allowed the ages of 1340 trees measured within fifty, 150 m2 quadrats in the Waiho Valley to be predicted. Ages of the oldest trees were then used to determine the time elapsed since deglaciation, or alternatively, the culmination of the preceding advance. The revised chronology showed that the LIA maximum of the FJG culminated by c. 1470-1530 AD, when the terminus was located approximately 4.5 km down-valley of its position in 2001. Subsequent, but smaller magnitude, re-advances culminated by c. 1580-1610 and c. 1790-1840 AD. Average terminus retreat rates after the LIA maximum varied between 7-9 m a-1 and reached 23 m a-1 by the early to mid-1800's, which suggests that climatic amelioration signalling the end of the LIA occurred in New Zealand by the early 19th Century.

  13. Climate Change of Franz Josef Land in the XX-XXI Centuries

    2016-04-01

    The results of climatic observations on the most northern land of Eurasia - Franz Josef Land, that was discovered in 1874, are presented. The gaps in the observations of the observatory named after Ernst Krenkel (Hayes's Island) were supplemented by calculations using reanalysis ERA Interim. It was received the positive trend in surface air temperature during 1958-2013. It is mainly achieved by increasing of the air temperature in winter but the summer trend is not statistically significant. Data of observation and reanalysis are perfectly correlated in cold period when underlying surface is uniform (correlation coefficient of more than 0.95). In summer, the correlation coefficients between the calculated and the real data are significantly lower (up to 0.68). This fact may be a consequence of the small values of the mean air temperatures of summer months (for example, during the July they varied in the interval -1-+2 degrees C.). Furthermore, it may be caused by the difficulty of model reproduction of the real state of the underlying surface, where land, ice, snow and water are chaotically combined. The analysis of circulation types by B.L. Dzerdzeevsky has shown that in the mid-XX Century, the northern meridional and western zonal types of circulation were replaced by southern meridional one, which prevailed during the first decade of the XXI too. This causes a reduction of the ice cover period, which resulted in a strengthening of the beach erosion and of slope processes. But short-term flows of warm air from the south, causing a catastrophic melting of glaciers, were also repeatedly marked in the past.

    Four new species are assigned to the genus Teretia Norman, 1888 in the family Raphitomidae Bellardi, 1875 and herein described: Teretia neocaledonica sp. nov., T. sysoevi sp. nov., T. tongaensis sp. nov. from the southeastern Pacific and Teretia tavianii sp. nov. from the Gulf of Aden. The new species represent the first Indo-Pacific record of a genus previously known in the recent molluscan fauna by only two species from the Atlantic Ocean-Mediterranean Sea and Southern Africa. A possible Tethyan origin for the genus Teretia is suggested.  PMID:25661630

    The 9 February 1971 earthquake in the San Fernando Valley damaged the Lower Van Norman Dam severely enough to warrant draining the reservoir. In March 1972 the sediment deposited on the reservoir floor was examined to determine whether the 1971 earthquake had induced sediment deformation and, if so, what types. A zone of deformational structures characterized by small-scale loads and slightly recumbent folds associated with the 1971 earthquake was discovered, in addition to two older zones of load structures. Each of the zones has been tentatively correlated with an historic earthquake.

  16. Features of shoreline displacement in the Holocene of Franz josef Land Archipelago

    Changes in the global sea level after the LGM caused the significant alteration in relation of land and sea in Arctic. The rise of the sea level in Arctic was accompanied with present tectonic processes. Marine terraces are formed with the combination of eustatic sea level fluctuations and glacioisostatic uplift of the territory with the significant role of complicated tectonic block movements. There are nearly about 150 radiocarbon ages data for Franz-Josef Land archipelago now. The represented conclusions are a generalization of the published data and results of our field researches with series of new radiocarbon dates. We managed to collect valuable factual material during the Russian Arctic National Park expedition in 2012. The distinctions of post-glacial rise of different islands and peculiarities of Holocene deglaciation were identified with the help of marine terraces analysis. The altitude of the terraces with the same age on different islands exceeds 15 meters in some cases. However, analysis of the data suggests that the continuous series of raised beaches from 35 m a.s.l. formed during the last 10000 years. It is impossible to build up an univocal model of emergence isobases with the existing data. Alexandra Land Island was the special object of this investigation. The large beach ridge from Lunar Ice Cap to Kropotkina Ice Cap divides the island on two parts. The northern one is covered with marine sediments, whereas the southern - with glaciofluvial sediments with negligible areas of marine sediments. The difference between the terraces' ages of Alexandra Land on the Dezhneva Bay shore and the northern shore of island suggests that: 1) In the early Holocene the rate of the transgression exceeded the tectonic uplift of the territory; 2) Formation of the large central beach ridge occurred near 6700 years ago, the maximum marine limit in the Alexandra Land Island; 3) The rate of the tectonic rise of the territory exceeded the eustatic sea level rise in

  18. Updating Norman's "Adequate Taxonomy": intelligence and personality dimensions in natural language and in questionnaires.

    Research on the dimensions of personality represented in the English language has repeatedly led to the identification of five factors (Norman, 1963). An alternative classification of personality traits, based on analyses of standardized questionnaires, is provided by the NEO (Neuroticism, Extraversion, Openness) model (Costa & McCrae, 1980b). In this study we examined the correspondence between these two systems in order to evaluate their comprehensiveness as models of personality. A sample of 498 men and women, participants in a longitudinal study of aging, completed an instrument containing 80 adjective pairs, which included 40 pairs proposed by Goldberg to measure the five dimensions. Neuroticism and extraversion factors from these items showed substantial correlations with corresponding NEO Inventory scales; however, analyses that included psychometric measures of intelligence suggested that the fifth factor in the Norman structure should be reconceptualized as openness to experience. Convergent correlations above .50 with spouse ratings on the NEO Inventory that were made three years earlier confirmed these relations across time, instrument, and source of data. We discuss the relations among culture, conscientiousness, openness, and intelligence, and we conclude that mental ability is a separate factor, though related to openness to experience.

    In recent years voxel phantoms have been developed on the basis of tomographic data of real individuals allowing new sets of conversion coefficients to be calculated for effective dose. Progress in radiation studies brought ICRP to revise its recommendations and a new report, already circulated in draft form, is expected to change the actual effective dose evaluation method. In the present paper the voxel phantom NORMAN developed at HPA, formerly NRPB, was employed with MCNP Monte Carlo code. A modified version of the phantom, NORMAN-05, was developed to take into account the new set of tissues and weighting factors proposed in the cited ICRP draft. Air kerma to organ equivalent dose and effective dose conversion coefficients for antero-posterior and postero-anterior parallel photon beam irradiations, from 20 keV to 10 MeV, have been calculated and compared with data obtained in other laboratories using different numerical phantoms. Obtained results are in good agreement with published data with some differences for the effective dose calculated employing the proposed new tissue weighting factors set in comparison with previous evaluations based on the ICRP 60 report.

  20. Expectable Earthquakes and their ground motions in the Van Norman Reservoirs Area

    The upper and lower Van Norman dams, in northwesternmost San Fernando Valley about 20 mi (32 km) northwest of downtown Los Angeles, were severely damaged during the 1971 San Fernando earthquake. An investigation of the geologic-seismologic setting of the Van Norman area indicates that an earthquake of at least M 7.7 may be expected in the Van Norman area. The expectable transitory effects in the Van Norman area of such an earthquake are as follows: peak horizontal acceleration of at least 1.15 g, peak velocity of displacement of 4.43 ft/sec (135 cm/sec), peak displacement of 2.3 ft (70 cm), and duration of shaking at accelerations greater than 0.05 g, 40 sec. A great earthquake (M 8+) on the San Andreas fault, 25 mi distant, also is expectable. Transitory effects in the Van Norman area from such an earthquake are estimated as follows: peak horizontal acceleration of 0.5 g, peak velocity of 1.97 ft/sec (60 cm/sec), displacement of 1.31 ft (40 cm), and duration of shaking at accelerations greater than 0.05 g, 80 sec. The permanent effects of the expectable local earthquake could include simultaneous fault movement at the lower damsite, the upper damsite, and the site proposed for a replacement dam halfway between the upper and lower dams. The maximum differential displacements due to such movements are estimated at 16.4 ft (5 m) at the lower damsite and about 9.6 ft (2.93 m) at the upper and proposed damsites. The 1971 San Fernando earthquake (M 6?) was accompanied by the most intense ground motions ever recorded instrumentally for a natural earthquake. At the lower Van Norman dam, horizontal accelerations exceeded 0.6 g, and shaking greater than 0.25 g lasted for about 13 see; at Pacoima dam, 6 mi (10 km) northeast of the lower dam, high-frequency peak horizontal accelerations of 1.25 g were recorded in two directions, and shaking greater than 0.25 g lasted for about 7 sec. Permanent effects of the earthquake include slope failures in the embankments of the upper

    It is an interesting quirk of medical history that the legacy of Norman Barrett most ostensibly lies in the name of a disease the he was quite emphatically wrong about, at least when he first described it. Indeed, there are those who argue to remove the eponym in favour of the title 'Columnar Lined Epithelium', in part because of what little Barrett actually had to do with the correct initial characterization of this disease. Yet the sum of Norman Barrett's contributions to modern medicine is much more than a mistaken characterization of a pathological process. Barrett was truly a pioneer of chest surgery in the UK - a specialty in its embryonic stages when he first qualified. He was also renowned as a teacher and academic of the highest calibre. In tracing the story of his life we can see how his natural attributes, life experiences and keen appreciation of the arts (especially history) facilitated personal success and such sharp insight into the vagaries of modern academic medicine.

    Effective dose is the main radiation protection quantity. Progresses in radiation studies brought ICRP to revise ICRP 60 recommendations. A new publication, already circulated in form of draft, is expected to change some aspects of effective dose evaluation method. The organ absorbed doses for neutrons at various energies and incidence angles, necessary to estimate the effective dose, have been published in ICRU 57 and ICRP 74 reports for ADAM and EVA analytical male and female phantoms and similar calculations were also performed, based on the MCNP code, for VIP-MAN voxel phantom. The NORMAN voxel phantom, developed on the basis of magnetic resonance data of an adult male at HPA (formerly NRPB), is an accurate model (with a voxel element of approximately 8 mm(3)), which well approximates the standard man and has been already employed for radiation protection studies with photons. In the present paper, a modified version, called NORMAN-05, including a new organ, the salivary glands (as suggested in the mentioned ICRP draft), and a more detailed skeletal description, especially devoted to red bone marrow dose evaluation, has been employed with the Monte Carlo code MCNPX to calculate neutron conversion coefficients from thermal energies to 20 MeV. Some preliminary results, for antero-posterior and postero-anterior irradiation conditions, are presented and compared with the available published data. PMID:17502319

Throughout his time in the Philippines, Camel collected examples of the flora and fauna, which he drew and described in detail. This paper offers an overview of his life, his publications and the Camel manuscripts, drawings and specimens that are preserved among the Sloane Manuscripts in the British Library and in the Sloane Herbarium at the Natural History Museum, London. It also discusses Camel's links and exchanges with scientifically minded plant collectors and botanists in London, Madras and Batavia.

    The Norman Rostoker Memorial Symposium brought together approximately 150 attendees to share their recent work and to reflect on the contributions of Norman Rostoker to the field of plasma physics and the advancement of fusion as a source of renewable clean energy. The field has changed considerably in a few short decades, with theoretical advances and technological innovations evolving in lock step. Over those same decades, our understanding of human induced climate change has also evolved; measurable changes in Earth's physical, chemical, and biological processes have already been observed, and these will likely intensify in the coming decades. Never before has the need for clean energy been more pronounced, or the need for transformative solutions more pressing. As scientists work with legislators, journalists, and the public to take actions to address the threat of climate change, there is much to be learned from the legacies of innovators like Norman Rostoker, who have tackled complex problems with scientific insight and determination even when the odds were stacked against them. I write this from the perspective on an Earth system scientist who studies photosynthesis and the biogeochemistry of the oceans, and my statements about plasma physics and Norman Rostoker are based on information I gathered from the colloquium and from many enjoyable conversations with his friends and colleagues.

    Abstract A new species of the mysid crustacean genus Gastrosaccus Norman, 1868 (Mysida, Mysidae, Gastrosaccinae) is reported from a sandy shore of Lombok Island, Indonesia. These specimens resemble G. sorrentoensis Wooldridge & McLachlan, 1986 and G. yuyu Bamber and Morton, 2012 by the possession of an articulated process on the fifth abdominal somite together with a fringe of spine-like filaments on the posterodorsal margin of the carapace. The Lombok population differs from the known congeners by having comparatively fewer numbers of carpopropod segments on the endopod of the third to eighth thoracic limbs and the conformation in the telson and in the male third pleopod. Hence, G. lombokiensis sp. n. is proposed herein as a third species of “G. sorrentoensis” species group. PMID:25197216

    Leachate plume emanating from an old unlined municipal landfill site near the city of Norman, Oklahoma, is discharging into the underlying alluvial aquifer. Subsurface imaging techniques, electrical resistivity tomography and electrical conductivity (EC) logging, were used on the site to detect and map the position of the leachate plume. Anomalous EC zones, delineated with the two methods, correlated with the occurrence of the plume detected by water chemistry analyses from multilevel monitoring wells. Specific conductance, a potential indicator of leachate contamination, ranged from 1861 to 7710 ??S/cm in contaminated zones and from 465 to 2180 ??S/cm in uncontaminated ground water. Results are in agreement with those from earlier studies that the leachate plume emerges from the landfill along preferential pathways. Additionally, there are indications that the leading edge of the plume has migrated, at least, 200 m away from the landfill in the direction of ground water flow. ?? 2006 National Ground Water Association.

    The Norman Landfill was selected for study as part of the U.S. Geological Survey Toxic Substances Hydrology Program in 1994. The landfill is located south of the City of Norman on alluvial deposits of the Canadian River. Type of waste deposited in the landfill from 1922 to 1973 was largely unrestricted and may include substances now recognized as hazardous. Dissolved and suspended substances leached from wastes in the closed and capped landfill are now in ground water extending toward the Canadian River as a plume of leachate. Water samples were collected from two stock wells, one domestic well, temporary drive-point wells, the Canadian River, and a small intermittent stream hydraulically downgradient of the capped landfill known as the slough. Most constituent concentrations were greater in ground water downgradient from the capped landfill than in background ground water and were greater in the slough than in the Canadian River. Concentrations of most constituents in the Canadian River, other than sulfate, manganese, and iron, were similar to concentrations in background ground water. Some constituents measured in ground-water for this investigation are potential indicators of leachate contamination. Potential indicators that could be used to differentiate leachate contaminated water from uncontaminated ground water of the alluvial aquifer include specific conductance, chloride, alkalinity, dissolved organic carbon, boron, and dD. Specific conductance and chloride were greater in water from wells downgradient of the landfill than water from background wells. Dissolved organic carbon and boron also were greater in the leachate contaminated ground water than in background ground water.

    The Norman Landfill is a closed municipal solid waste landfill located on an alluvium associated with the Canadian River in Norman, Oklahoma. It has operated as a research site since 1994 because it is typical of many closed landfill sites across the U.S. Leachate from the unlined landfill forms a groundwater plume that extends downgradient approximately 250 m from the landfill toward the Canadian River. To investigate the impact of the landfill leachate on the diversity and functional structure of microbial communities, groundwater samples were taken from eight monitoring wells at a depth of 5m, and analyzed using a comprehensive functional gene array covering about 50,000 genes involved in key microbial processes, such as biogeochemical cycling of C, N, P, and S, and bioremediation of organic contaminants and metals. Wells are located within a transect along a presumed flow path with different distances to the center of the leachate plume. Our analyses showed that microbial communities were obviously impacted by the leachate-component from the landfill. The number of genes detected and microbial diversity indices in the center (LF2B) and its closest (MLS35) wells were significantly less than those detected in other more downgradient wells, while no significant changes were observed in the relative abundance (i.e., percentage of each gene category) for most gene categories. However, the microbial community composition or structure of the landfill groundwater did not clearly show a significant correlation with the distance from well LF2B. Burkholderia sp. and Pseudomonas sp. were found to be the dominant microbial populations detected in all wells, while Bradyrhizobium sp. and Ralstonia sp. were dominant populations for seven wells except LF2B. In addition, Mantel test and canonical correspondence analysis (CCA) indicate that pH, sulfate, ammonia nitrogen and dissolved organic carbon (DOC) have significant effects on the microbial community structure.

    We examined diatom assemblages from 18 stream and pond samples in the Franz Josef Land Archipelago (FJL), the most northern land of Eurasia. More than 216 taxa were observed, revealing a rich circumpolar diatom flora, including many undescribed taxa. Widely distributed taxa were the most abundant by cell densities, while circumpolar taxa were the most species rich. Stream and pond habitats hosted different assemblages, and varied along a pH gradient. Diatoma tenuis was the most abundant and ubiquitous taxon. However, several circumpolar taxa such as Chamaepinnularia gandrupii, Cymbella botellus, Psammothidium sp. and Humidophila laevissima were also found in relatively high abundances. Aerophilic taxa were an important component of FJL diatom assemblages (Humidophila spp., Caloneis spp. and Pinnularia spp.), reflecting the large and extreme seasonal changes in Arctic conditions. We predict a decrease in the abundance of circumpolar taxa, an increase in local (α-) freshwater diatom diversity, but a decrease in regional diversity (circumpolar homogenization) as a result of current warming trends and to a lesser extent the increasing human footprint in the region.

    2011-05-01

    Darker skin correlates with reduced opportunities and negative health outcomes. Recent discoveries related to the genes associated with skin tone, and the historical use of cosmetics to conform to racist appearance standards, suggest effective skin-lightening products may soon become available. This article examines whether medical interventions of this sort should be permitted, subsidized, or restricted, using Norman Daniels's framework for determining what justice requires in terms of protecting health. I argue that Daniels's expansive view of the requirements of justice in meeting health needs offers some support for recognizing a societal obligation to provide this kind of 'enhancement,' in light of the strong connections between skin tone and health outcomes. On balance, however, Daniels's framework offers compelling reasons to reject insurance coverage for skin-lightening medical interventions, including the likely ineffectiveness of such technologies in mitigating racial health disparities, and the danger that covering skin-lightening enhancements would undermine public support for cooperative schemes that protect health. In fact, justice may require limiting access to these technologies because of their potential to exacerbate the negative effects of racism. PMID:19747347

    2015-01-01

    When Norman Geschwind (1926-1984) attended medical school in the 1940s, his psychiatry professors taught as if behavior were unrelated to neuropathology. The focus of neurology remained the diagnosis and treatment of aphasias and epilepsies, while cognitive impairments and developmental disorders were classified as functional (psychological) disorders. Geschwind was troubled by the fact that many of the patients he saw with neurological deficits also presented with behavioral (developmental) disorders. Geschwind's generation also had been taught that aphasias resulted from global rather than localized or focal neurological lesions. These holists, including the prepsychoanalytic Sigmund Freud, targeted the work of aphasiologist Carl Wernicke as an exemplar of the flaws of the localizationist hypothesis. Reading Wernicke in the original, Geschwind discovered a complex and multilayered explanation for aphasias that implicated lesions located in association pathways that, when extensive, resulted in behavioral disorders. Geschwind also reread the works of the holists, discovering that, while their rhetoric rejected Wernicke, their explanations of aphasias actually reinforced Wernicke's hypothesis. Building on his reading of these historical documents and his clinical experiences, Geschwind urged the resurrection of Wernicke's disconnection syndromes that Geschwind labeled as Behavioral Neurology.

    The 20 per cent rule proposed by Norman established a guideline using radioactivity in the minimally invasive radioguided parathyroidectomy (MIRP) technique to localize and confirm removal of an abnormal parathyroid gland in patients with primary hyperparathyroidism. If radioactivity in the resected gland was at least 20 per cent of excision site/background radioactivity, the 20 per cent rule was satisfied. Patients meeting these criteria underwent unilateral MIRP without intraoperative parathyroid hormone assay or intraoperative frozen section. The study aim was to independently evaluate the 20 per cent rule in MIRP patients with primary hyperparathyroidism. Using the University of Louisville Parathyroid Database from January 1, 1999 to December 31, 2007, 216 MIRP patients with complete radioguided and postoperative management data were identified. The average percentage of ex vivo parathyroid gland radioactivity compared with excision site/background radioactivity was 107 per cent with a range from 14 to 388 per cent. For 99 per cent (196/198) radioactivity recorded from the excised gland was at least 20 per cent of radioactivity recorded from the excision site. Normocalcemia was documented in 98.5 per cent (195/198) at 12 month follow-up. Our data supports the 20 per cent rule in that in 99 per cent of MIRP patients the resected gland radioactivity was at least 20 per cent of excision site radioactivity allowing localization and confirmation of an overactive gland without intraoperative parathyroid hormone monitoring or tissue analysis.

  18. Age rationing and prudential lifespan account in Norman Daniels’ Just health

    PubMed Central

    Brauer, S

    2009-01-01

    Could age be a valid criterion for rationing? In Just health, Norman Daniels argues that under certain circumstances age rationing is prudent, and therefore a morally permissible strategy to tackle the problem of resource scarcity. Crucial to his argument is the distinction between two problem-settings of intergenerational equity: equity among age groups and equity among birth cohorts. While fairness between age groups can involve unequal benefit treatment in different life stages, fairness between birth cohorts implies enjoying approximate equality in benefit ratios. Although both questions of fairness are distinct, the resolution of the one depends on resolution of the other. In this paper, I investigate whether Daniels’ account of age rationing could be defended as a fair way of setting limits to healthcare entitlements. I will focus on two main points. First, I will consider whether the age group problem could be resolved without appealing to a conception of the good. Second, I will demonstrate that the connection between the age group problem and the birth cohort problem runs deeper than Daniels initially thought—and that it ultimately suggests a method for prioritisation in problem solving strategies.

    Josef Armin Knapp (1843-1899) as Austrian botanist was interested in development of botanical knowledge of Austro-Hungarian Monarchy--his maternal country. Monarchy, during the long regency of emperor Franz Josef I, was multinational, very much diversified geographically territory. This large empire had included, among others, such countries as present Austria, Hungary, Slovakia, Croatia, Ukraine, Romania and the southern part of present Poland--previously known as Galicia. J. A. Knapp was interested in studying these parts of empire which were considered peripheries and less-known. It seems to have met the requirements of science, economy and administration of Vienna. J. A. Knapp in his large floristic researches had included explorations of considerable part of the Monarchy and had left an interesting scientific legacy. His research papers were results of botanical explorations in selected areas of the Monarchy--area of Nitra (currently a city in Slovakia), Slavonia (presently a land in Croatia) and Galicia (the historical area in the south of Poland). This article refers to the botanical journey of J. A. Knapp in Galicia in summer 1868. The main purpose of his journey was to visit and explore selected places in Galicia--the surroundings of Jaslo and Sanok towns and some specific areas within the Bieszczady Mountains, which are part of the Carpathians Mountains. Botanical researches in the Bieszczady Mountains provided by J. A. Knapp can be considered nowadays as very important and pioneering in that area. In the second part of XIX century this area was highly populated and the observed anthropogenic pressure applied to the nature was strong. Now, the area is considered a very valuable natural territory--since 1973 it has been occupied by the Bieszczady National Park--one of Polish national parks. J. A. Knapp had spent more than two months in Galicia thanks to the great hospitality of Polish people, especially botanists: A. Rehmann, I. R. Czerwiakowski, W. Jab

    Biological psychiatry in the early twentieth century was based on interrelated disciplines, such as neurology and experimental biology. Neuropsychiatrist Franz Josef Kallmann (1897-1965) was a product of this interdisciplinary background who showed an ability to adapt to different scientific contexts, first in the field of neuromorphology in Berlin, and later in New York. Nonetheless, having innovative ideas, as Kallmann did, could be an ambiguous advantage, since they could lead to incommensurable scientific views and marginalization in existing research programs. Kallmann followed his Dr. Med. degree (1919) with training periods at the Charité Medical School in Berlin under psychiatrist Karl Bonhoeffer (1868-1948). Subsequently, he collaborated with Ernst Ruedin (1874-1952), investigating sibling inheritance of schizophrenia and becoming a protagonist of genetic research on psychiatric conditions. In 1936, Kallmann was forced to immigrate to the USA where he published The Genetics of Schizophrenia (1938), based on data he had gathered from the district pathological institutes of Berlin's public health department. Kallmann resumed his role as an international player in biological psychiatry and genetics, becoming president (1952) of the American Society of Human Genetics and Director of the New York State Psychiatric Institute in 1955. While his work was well received by geneticists, the idea of genetic differences barely took hold in American psychiatry, largely because of émigré psychoanalysts who dominated American clinical psychiatry until the 1960s and established a philosophical direction in which genetics played no significant role, being regarded as dangerous in light of Nazi medical atrocities. After all, medical scientists in Nazi Germany had been among the social protagonists of racial hygiene which, under the aegis of Nazi philosophies, replaced medical genetics as the basis for the ideals and application of eugenics.

  1. Geomorphic and hydrologic assessment of erosion hazards at the Norman municipal landfill, Canadian River floodplain, Central Oklahoma

    2003-01-01

    The Norman, Oklahoma, municipal landfill closed in 1985 after 63 years of operation, because it was identified as a point source of hazardous leachate composed of organic and inorganic compounds. The landfill is located on the floodplain of the Canadian River, a sand-bed river characterized by erodible channel boundaries and by large variation in mean monthly discharges. In 1986, floodwaters eroded riprap protection at the southern end of the landfill and penetrated the landfill's clay cap, thereby exposing the landfill contents. The impact of this moderate-magnitude flood event (Q12) was the catalyst to investigate erosion hazards at the Norman landfill. This geomorphic investigation analyzed floodplain geomorphology and historical channel changes, flood-frequency distributions, an erosion threshold, the geomorphic effectiveness of discharge events, and other factors that influence erosion hazards at the landfill site. The erosion hazard at the Norman landfill is a function of the location of the landfill with respect to the channel thalweg, erosional resistance of the channel margins, magnitude and duration of discrete discharge events, channel form and hydraulic geometry, and cumulative effects related to a series of discharge events. Based on current climatic conditions and historical channel changes, a minimum erosion threshold is set at bankfull discharge (Q = 572 m3/s). The annual probability of exceeding this threshold is 0.53. In addition, this analysis indicates that peak stream power is less informative than total energy expenditures when estimating the erosion potential or geomorphic effectiveness of discrete discharge events. On the Canadian River, long-duration, moderate-magnitude floods can have larger total energy expenditures than shorter-duration, high-magnitude floods and therefore represent the most serious erosion hazard to floodplain structures.

    2002-01-01

    The City of Norman operated a solid-waste municipal landfill at two sites on the Canadian River alluvium in Cleveland County, Oklahoma from 1970 to 1985. The sites, referred to as the west and east cells of the landfill, were originally excavations in the unconsolidated alluvial deposits and were not lined. Analysis of ground-water samples indicate that leachate from the west cell is discharging into an adjacent abandoned river channel, referred to as the slough, and is migrating downgradient in ground water toward the Canadian River. The report describes the hydrogeologic features at the landfill, including the topography of the bedrock, water-level changes in the alluvial aquifer, and delineates the leachate plume using specific conductance data. The leading edge of the leachate plume along the 35-80 transect extended over 250 meters downgradient of the west cell. The leading edge of the leachate plume along the 40-SOUTH transect had moved about 60 meters from the west cell in a south-southwesterly direction and had not moved past the slough as of 1997. Specific conductance measurements exceeding 7,000 microsiemens per centimeter at site 40 indicate the most concentrated part of the plume remained in the upper half of the alluvial aquifer adjacent to the west cell. The direction of ground-water flow in the alluvial aquifer surrounding the landfill was generally north-northeast to south-southwest toward the river. However, between the west cell and the slough along the 40-SOUTH transect, head measurements indicate a directional change to the east and southeast toward a channel referred to as the sewage outfall. Near the 35-80 transect, at 0.5 meter below the water table and at the base of the aquifer, the direction of ground-water flow was south-southeast with a gradient of about 30 centimeters per 100 meters. Generally, ground-water levels in the alluvial aquifer were higher during the winter months and lower during summer months, due to a normal decrease in

    The predatory fish community and their prey in the Norman Rivere estuary, Gulf of Carpentaria Australia, are compared with the communities of other tropical inshore areas, to investigate patterns of predation in tropical inshore areas particularly in relation to penaeid prawns. Abiotic factors (turbidity, freshwater input) and diversity of habitat types affect the composition of both prey and predator communities, resulting in large differences in the communities of tropical inshore waters. The stomach contents of 2059 predatory fish from the Norman River estuary were analysed over four sampling trips in the wet and dry seasons. The stomachs of 61% (1255 fish) of 54 species contained a total of 676·2 g (dry weight) of food, while 39% (804 fish) were empty. Teleosts were the main component of the diet (by dry weight) of 13 of the 22 species analysed, followed by annelids for two species. Five species had only teleosts in their stomachs. Most predator species ate benthic or bentho-pelagic prey, while three species— Rhizoprionodon taylori, Scomberoides commersonianusand Leptobrama mulleri—ate mainly pelagic prey. Although 19 species ate some penaeids, only Polydactylus sheridaniate little else. This species, Lates calcariferand Eleutheronema tetradactylumate 94·5% of all the penaeid prey and 97·9% of all the commercially important penaeid prey recorded in the study. Penaeid predation indices (calculated from gillnet catch rates, proportion of penaeids in the diet and a consumption rate of 3% body weight per day) were 0·23 g of penaeid per net-metre per day for P. sheridani, 0·15 for L. calcariferand 0·03 for E. tetradactylum. Commercially important penaeid predation indices were 0·11, 0·13 and 0·01, respectively. These values are intermediate between those previously recorded for the main penaeid predators in other inshore areas of the Gulf of Carpentaria (Embley River estuary and Groote Eylandt).

    Ground-motion recordings obtained at the Van Norman Complex from the 1994 Northridge, California, mainshock and its aftershocks constitute an excellent data set for the analysis of soil response as a function of ground-motion amplitude. We searched for nonlinear response by comparing the Fourier spectral ratios of two pairs of sites for ground motions of different levels, using data from permanent strong-motion recorders and from specially deployed portable instruments. We also compared the amplitude dependence of the observed ratios with the amplitude dependence of the theoretical ratios obtained from 1-D linear and 1-D equivalent-linear transfer functions, using recently published borehole velocity profiles at the sites to provide the low-strain material properties. One pair of sites was at the Jensen Filtration Plant (JFP); the other pair was the Rinaldi Receiving Station (RIN) and the Los Angeles Dam (LAD). Most of the analysis was concentrated on the motions at the Jensen sites. Portable seismometers were installed at the JFP to see if the motions inside the structures housing the strong-motion recorders differed from nearby free-field motions. We recorded seven small earthquakes and found that the high-frequency, low-amplitude motions in the administration building were about 0.3 of those outside the building. This means that the lack of high frequencies on the strong-motion recordings in the administration building relative to the generator building is not due solely to nonlinear soil effects. After taking into account the effects of the buildings, however, analysis of the suite of strong- and weak-motion recordings indicates that nonlinearity occurred at the JFP. As predicted by equivalent-linear analysis, the largest events (the mainshock and the 20 March 1994 aftershock) show a significant deamplification of the high-frequency motion relative to the weak motions from aftershocks occurring many months after the mainshock. The weak-motion aftershocks

    Norman Bethune became famous through his work in the Spanish Civil War, his advocacy of socialised medicine in North America and his association with Mao Zedong's revolutionary movement in China. It has been suggested that he may have been descended from the Bethune or Beaton medical dynasty, who for generations served as physicians to kings of Scotland, the Lords of the Isles and to some of the larger Scottish clans. This paper traces his lineage back to the Isle of Skye. In the absence of old parish records as aids to tracing genealogy, other available evidence has confirmed that Bethune was indeed in the direct line of descent from the Bethunes or Beatons of Husabost, in Skye, one of the largest branches of this medical kindred, who were physicians to the MacLeods of Dunvegan.

    The City of Norman, Oklahoma, wanted to augment its water supplies to meet the needs of an increasing population. Among the city’s potential water sources are city wells that produce water that exceeds the 10 micrograms per liter primary drinking-water standard for arsenic. The City of Norman was interested in investigating low-cost means of using natural attenuation to remove arsenic from well water and augment the water supply of Lake Thunderbird, the primary water source for the city. The U.S. Geological Survey, in cooperation with the City of Norman, conducted a preliminary investigation (pilot study) to determine if discharge of water from those wells into the Little River over a 12-day period would reduce arsenic concentrations through natural-attenuation processes. Water in the Little River flows into Lake Thunderbird, the principal water source for the city, so the discharged well water would improve the water balance of that reservoir. During this pilot study, 150–250 gallons per minute from each of six city wells were discharged to the Little River over a 12-day period. Water-quality samples were collected from the wells during discharge and from the river before, during, and after well discharges. Streambed-sediment samples were collected at nine sites in the river before and after the well-discharge period. Water discharge from the six wells added 0.3 kilogram per day of arsenic to the river at the nearest downstream streamflow-gaging station. Dissolved arsenic concentration in the Little River at the closest downstream sampling site from the wells increased from about 4 micrograms per liter to as much as 24 micrograms per liter. Base flow in the river increased by about 1.7 cubic feet per second at the nearest downstream streamflow-gaging station. Streamflow in the river was two-thirds of that expected from the amount of water discharged from the wells because of seepage to soils and evapotranspiration of well water along drainage ways to the river

    The Middle-Upper Devonian Kee Scarp reef complexes of Norman Wells, Northwest Territories, Canada, are oil-producing, stromatoporoid-dominated carbonates. Episodic increases in the rate of sea level rise produced multiple cycles of reef growth that exhibit backstepping characteristics. These carbonates, composed of invariably altered limestones, have original interskeletal, intraskeletal, and intergranular porosity, mostly occluded by nonferroan, dull luminescent cements. Secondary porosity, represented by micropores of various types, developed during diagenesis by aggrading neomorphism and dissolution. The micropores represent the main reservoir porosity in the Kee Scarp limestone. Petrographic, chemical, and isotopic studies of Kee Scarp reef components reveal a complex diagenetic history involving marine fluids modified by increasing water/rock interaction and burial. Neomorphic stabilization of skeletal components caused further depletion in {gamma}{sup 18}O but very little change in {gamma}{sup 13}C, an argument for modification of the original marine fluids with increasing burial. Variations in magnitude of water/rock interaction with depth, facies changes, and porosity modifications probably exerted some control on fractionation and distribution of stable isotopes and trace elements in reef components.

    Results of physical and chemical analyses of sediment and water collected near a closed municipal landfill at Norman, Oklahoma are presented in this report. Sediment analyses are from 40 samples obtained by freeze-shoe coring at 5 sites, and 14 shallow (depth <1.3 m) sediment samples. The sediment was analyzed to determine grain size, the abundance of extractable iron species and the abundances and isotopic compositions of forms of sulfur. Water samples included pore water from the freeze-shoe core, ground water, and surface water. Pore water from 23 intervals of the core was collected and analyzed for major and trace dissolved species. Thirteen ground-water samples obtained from wells within a few meters of the freeze-shoe core sites and one from the landfill were analyzed for major and trace elements as well as the sulfur and oxygen isotope composition of dissolved sulfate. Samples of surface water were collected at 10 sites along the Canadian River from New Mexico to central Oklahoma. These river-water samples were analyzed for major elements, trace elements, and the isotopic composition of dissolved sulfate.

    If an antenna is located close to a person, the electric and magnetic fields produced by the antenna will vary in the region occupied by the human body. To obtain a mean value of the field for comparison with reference levels, the Institute of Electrical and Electronic Engineers (IEEE) and International Commission on Non-Ionizing Radiation Protection (ICNIRP) recommend spatially averaging the squares of the field strength over the height the body. This study attempts to assess the validity and accuracy of spatial averaging when used for half-wave dipoles at frequencies between 65 MHz and 2 GHz and distances of lambda/2, lambda/4 and lambda/8 from the body. The differences between mean electric field values calculated using ten field measurements and that of the true averaged value were approximately 15% in the 600 MHz to 2 GHz range. The results presented suggest that the use of modern survey equipment, which takes hundreds rather than tens of measurements, is advisable to arrive at a sufficiently accurate mean field value. Whole-body averaged and peak localized SAR values, normalized to calculated spatially averaged fields, were calculated for the NORMAN voxel phantom. It was found that the reference levels were conservative for all whole-body SAR values, but not for localized SAR, particularly in the 1-2 GHz region when the dipole was positioned very close to the body. However, if the maximum field is used for normalization of calculated SAR as opposed to the lower spatially averaged value, the reference levels provide a conservative estimate of the localized SAR basic restriction for all frequencies studied.

    The U.S. Court of Appeals for the Ninth Circuit overturned the lower court's dismissal and allowed clerical or administrative workers to sue their employer for testing for "highly private and sensitive medical genetic information such as syphilis, sickle cell trait, and pregnancy" without either their consent or their knowledge during a general employee health examination. The court noted that "the most basic violation possible" of constitutional privacy interests involves the performance of unauthorized testing for medical information and that such testing may be viewed as illegal search under the Fourth Amendment in addition to violation of due process under the Fifth or Fourteenth Amendments. Because there are "few subject areas more personal and more likely to implicate privacy interests than that of one's health or genetic make-up," the court concluded that the unauthorized testing constituted a significant invasion of the right to privacy under the Fourth Amendment. The court reasoned that neither consent to a general medical examination nor consent to providing blood or urine samples abolishes the privacy right not to be tested for intimate, personal matters involving one's health. Also, because black employees were singled out for sickle cell trait testing and female employees for pregnancy testing, the employer discriminated against them concerning terms or conditions of employment, thus violating Title VII of the Civil Rights Act.

    Election years in Britain, the USA, France, and Italy have not granted the environment a high place on the political agenda even in the year of the UN Conference on Environment and Development (UNCED). The erosion of the natural resources base is not included as natural resource accounting in the computation of gross national product (GNP). In countries such as Germany, Australia, Indonesia, and Costa Rica, 50% of GNP growth annually is cancelled out by soil erosion, pollution, excessive logging, and other environmental degradation. The economic health of the country including recovery from recessions is related to environmental protection. The economic practices involve ecological deficit accounting. It has been suggested by Lester Brown of the Worldwatch Institute that an economical deflator is needed to gage economic progress. The ecological illiteracy of politicians prevents the American people from realizing the actual cost of ignoring the problems. Politicians fight against raising taxes on gasoline and ignore the cost of carbon dioxide emissions and destabilization of climate. Americans pay a 1/4 the price Europeans pay for gasoline. Energy conservation must be expanded from current levels. Improvements have been made since the first OPEC price hike in 1973; the economy saved $100 billion a year and improved efficiency and production. American conservation in line with European conservation would save $200 billion a year; matching Japanese conservation would generate a savings of $300 billion. This sum exceeds the Federal deficit or the Pentagon budget. It is enough to save 8 million children who die from preventable causes or provide $4.5 billion/year annually to the year 2000 for foreign aid for UN family planning programs. The savings compares favorable with the UNCED estimates of $125 billion/year for environmental protection in the South. The question is whether politicians really would be committing political suicide by listening less to oil and car lobbyists and listening more to those promoting long term interests and security.

    New paleomagnetic data were obtained from a total of 158 oriented samples collected from the Jurassic magmatic complexes exposed on the Franz Joseph Land Archipelago (FJL). The field work was conducted during 2011 field season. Present study was focused on the tholeiitic basaltic lava flows that crop out on the Hooker Island. The samples were subjected to a detailed step-wise thermal demagnetization in temperatures up to 600 deg C or alternating field demagnetization with maximum filed up to 140 mT. Natural remanent magnetization (NRM) was measured with a 2G cryogenic magnetometer or a JR-6A spin-magnetometer housed in a magnetically shielded room at the Institute of Petroleum Geology and Geophysics, Siberian Branch of Russian Academy of Sciences. The main NRM carriers in the FJL samples are titanomagnetites with varying Ti-content. Magnetic remanence was unblocked in temperatures of 350-400 deg C. Some samples are characterized by unblocking temperatures of 560 deg C. The new paleomagnetic data were combined with those previously obtained from the early Cretaceous volcanics exposed on the FJL. A new mean paleomagnetic direction for the Jurassic rocks was calculated as D=78.3 deg, I=74.7 deg, a95=3.1 deg, k=194.3, N=13. A corresponding paleomagnetic pole is now located at Plat=62.1 deg; Plon=136.5 deg, A95=5.5 deg, K=63.6. New results suggest that the JFL occupied a significantly different position from that of the present day. However, in early Cretaceous the JFL was already located close to its present day position. We propose a rifting event between the North Barentz terrane (FJL and possibly Svalbard) and the counterpart of European tectonic domain. The rifting occurred during Early-Middle Jurassic. This event was accompanied by a significant shift of the FJL to the north-east for approximately 500 km. New results are in good agreement with a hypothesis that the FJL was passing over the Icelandic-Siberian hot spot during the Jurassic-Cretaceous time. Paleolatitudes for the Hooker Island correspond to its present latitude and the paleolatitude of the Siberian trapps. The reported results are preliminary and cannot lead to any ultimate interpretation. Further investigations are needed.

    Timmie, William P.

    2009-01-01

    Work in our laboratory has focused on the mechanisms by which cytokines can influence the brain and behavior in humans and non-human primates. Using administration of interferon (IFN)-alpha as a tool to unravel these mechanisms, we have expanded upon findings from the basic science literature implicating cytokine-induced changes in monoamine metabolism as a primary pathway to depression. More specifically, a role for serotonin metabolism has been supported by the clinical efficacy of serotonin reuptake inhibitors in blocking the development of IFN-alpha-induced depression, and the capacity of IFN-alpha to activate metabolic enzymes (indolamine 2,3 dioxygenase) and cytokine signaling pathways (p38 mitogen activated protein kinase) that can influence the synthesis and reuptake of serotonin. Our data also support a role for dopamine depletion as reflected by IFN-alpha-induced changes in behavior (psychomotor slowing and fatigue) and regional brain activity, which implicate the involvement of the basal ganglia, as well as the association of IFN-alpha-induced depressive-like behavior in rhesus monkeys with decreased cerebrospinal fluid concentrations of the dopamine metabolite, homovanillic acid. Neuroimaging data in IFN-alpha-treated patients also suggest that activation of neural circuits (dorsal anterior cingulate cortex) associated with anxiety and alarm may contribute to cytokine-induced behavioral changes. Taken together, these effects of cytokines on the brain and behavior appear to subserve competing evolutionary survival priorities that promote reduced activity to allow healing, and hypervigilance to protect against future attack. Depending on the relative balance between these behavioral accoutrements of an activated innate immune response, clinical presentations may be distinct and warrant individualized therapeutic approaches.

    Water samples have been collected at two sites on the Wild Rice River since September 1974 to establish baseline water-quality characteristics before construction of a reservoir for recreation and flood control near Twin Valley, Minn. A decline in water quality between the sites is shown by mean total phosphorus concentrations, which increase from 0.06 to 0.10 milligram per liter downstream, and mean turbidity, which increases from 12 to 24 units downstream. Phosphorus and ammonia concentrations, as high as 0.31 and 2.7 milligrams per liter, respectively, could be the result of domestic waste input to the river upstream from Hendrum. Biochemical oxygen demand concentrations were significantly higher during spring runoff than during the rest of the year. Four out of 90 bacteria samples taken at Twin Valley indicate the presence of human fecal material, though bacteria densities do not exceed recommendations of the U.S. Environmental Protection Agency for public-water supplies. The dominace of organic-pollution tolerant phytoplankton in 49 out of 78 samples also indicates degradation of the river quality at Twin Valley. Nutrient concentrations at Twin Valley have no apparent effect on phytoplankton concentrations. None of the consitituents sampled were found to exceed recommended concentrations for public-water supplies.

    In Germany the BFU (German Federal Bureau of Aircraft Accidents Investigation) is authorized to investigate accidents and serious incidents to civil aircraft in Germany, to determine the causes of the occurrences. The German National Meteorological Service (DWD) is responsible for the meteorological part of the investigation. The results of these determinations form the basis for safety recommendations and advisory notices, statistical analyses, research, safety studies and ultimately accident prevention programs. In this work the authors would like to present the meteorological investigation of an accident on 26 December 2001. The accident took place just a few seconds after take-off from the regional airport Bremerhaven near the German North Sea coast. This day the temperature was arround 0^o C, the wind was weak and several snow, snow/rain and rain showers were observed. Approximate half an hour before take-off a snow shower results in 1-4 cm snow at the airport area of Bremerhaven. The pilot attemped to brush some of the snow from the top of the aircraft wings, but was unable to get all of it. He decided to go. Once airborne, the aircraft stalled and crashed into a river approximate 1 km behind the runway. The question of the meteorological investigation was, could a snow or ice cover adhere on top of the wings of the aircraft after take-off.

    The eye lenses of the Antarctic nototheniid fishes that inhabit the perennially freezing Antarctic seawater are transparent at -2 degrees C, whereas the cold-sensitive mammalian and tropical fish lenses display cold-induced cataract at 20 degrees C and 7 degrees C, respectively. No cold-cataract occurs in the giant Antarctic toothfish Dissostichus mawsoni lens when cooled to temperatures as low as -12 degrees C, indicating highly cold-stable lens proteins. To investigate this cold stability, we characterised the lens crystallin proteins of the Antarctic toothfish, in parallel with those of the sub-tropical bigeye tuna Thunnus obesus and the endothermic cow Bos taurus, representing three disparate thermal climes (-2 degrees C, 18 degrees C and 37 degrees C, respectively). Sizing chromatography resolved their lens crystallins into three groups, alpha/betaH, beta and gamma, with gamma crystallins being the most abundant (>40%) lens proteins in fish, in contrast to the cow lens where they comprise only 19%. The upper thermal stability of these crystallin components correlated with the body temperature of the species. In vitro chaperone assays showed that fish alpha crystallin can protect same-species gamma crystallins from heat denaturation, as well as lysozyme from DTT-induced unfolding, and therefore are small Heat Shock Proteins (sHSP) like their mammalian counterparts. Dynamic light scattering measured an increase in size of alphagamma crystallin mixtures upon heating, which supports formation of the alphagamma complex as an integral part of the chaperone process. Surprisingly, in cross-species chaperone assays, tuna alpha crystallins only partly protected toothfish gamma crystallins, while cow alpha crystallins completely failed to protect, indicating partial and no alphagamma interaction, respectively. Toothfish gamma was likely to be the component that failed to interact, as the supernatant from a cow alpha plus toothfish gamma incubation could chaperone cow gamma crystallins in a subsequent heat incubation, indicating the presence of uncomplexed cow alpha. This suggests that the inability of toothfish gamma crystallins to fully complex with tuna alpha, and not at all with the cow alpha crystallins, may have its basis in adaptive changes in the protein that relate to the extreme cold-stability of the toothfish lens.

    Thrombosis and inflammation are hallmarks of ischemic stroke still unamenable to therapeutic interventions. High-molecular-weight kininogen (KNG) is a central constituent of the contact-kinin system which represents an interface between thrombotic and inflammatory circuits and is critically involved in stroke development. Kng(-/-) mice are protected from thrombosis after artificial vessel wall injury and lack the proinflammatory mediator bradykinin. We investigated the consequences of KNG deficiency in models of ischemic stroke. Kng(-/-) mice of either sex subjected to transient middle cerebral artery occlusion developed dramatically smaller brain infarctions and less severe neurologic deficits without an increase in infarct-associated hemorrhage. This protective effect was preserved at later stages of infarction as well as in elderly mice. Targeting KNG reduced thrombus formation in ischemic vessels and improved cerebral blood flow, and reconstitution of KNG-deficient mice with human KNG or bradykinin restored clot deposition and infarct susceptibility. Moreover, mice deficient in KNG showed less severe blood-brain barrier damage and edema formation, and the local inflammatory response was reduced compared with controls. Because KNG appears to be instrumental in pathologic thrombus formation and inflammation but dispensable for hemostasis, KNG inhibition may offer a selective and safe strategy for combating stroke and other thromboembolic diseases.

    Cell death is a physiological process which is required for normal development and existence of multi-cellular organisms. Physiological cell death, or apoptosis, is controlled by an evolutionarily conserved mechanism. Abnormalities in this process are implicated as a cause or contributing factor in a variety of diseases. Inhibition of apoptosis can promote neoplastic transformation, particularly in combination with dysregulated cell-cycle control, and can influence the response of tumour cells to anti-cancer therapy. Molecular biological and biochemical approaches are used to find missing cell-death regulators and to define signalling cascades, while experiments in genetically modified mice will identify the essential function of these molecules. Discoveries from cell death research should provide clues for designing therapies for a variety of diseases, including degenerative disorders, auto-immunity and cancer. PMID:10225436

    Tectonic evolution and structural complexities of the Snake River Plain (SRP), the role of extension in its formation, and the effects of the YellowStone (YS) hotspot track have been a topic of scientific discussion for decades. In this research, we are addressing some of these issues by focusing on the Western Snake River Plain (WRSP) using a pre-existing gravity and magnetic database compiled through a community effort. These data are available at the Pan American Center for Environmental studies (http://research.utep.edu/paces). In the regional context of the SRP, the Complete Bouguer Anomaly (CBA) ranges by about 210 mGal with the highest value in the vicinity of the WRSP. We used upward continuation filters, bandpass filters, and directional derivative filters to delineate features by wavelength and trend. Total Magnetic Intensity (TMI) was also analyzed. The magnetic intensity ranges over 600 nT with much more complex and erratic magnetic signatures that arise from the shallow basalt and rhyolite deposits within the region. We used pseudogravity and tilt derivative filters for further processing of the magnetic data. We are able to identify the major structural components in the area using gravity and magnetic data and their processing. The bounding normal faults of the WSRP are well observed. We constructed an axial gravity profile along the SRP starting at Walla Walla, Washington and extending through Yellowstone to Reygate, Montana. CBA values along this profile show that the western and central sections of the SPR have higher gravity anomaly values than the eastern sections and the YS area. We used forward gravity modeling of the subsurface structures across the WSRP starting from the Basin and Range province on the southwest to the Atlanta Lobe of the Idaho Batholith on the northeast. From the model, we observed that the Moho depth increases northeastward and varies between 30 and 46 km along the profile. These results match with receiver function Moho depth estimates from the EARTHSCOPE US Array. We used borehole data and shallow seismic survey results to constrain the upper 5 km of the model along the profile. A number of normal faults that form a series of grabens and half grabens were also modeled beneath the SRP. The gravity profile suggests that a higher density mafic intrusive body of about 8-10 km thickness lies directly beneath the WSRP. This body is possibly a mafic intrusion into the upper crust or could be a region of the middle and upper crust that was extensively intruded by sills and dikes during the time of extension in the area. This result agrees with other scientific results in the eastern SRP based on seismic data. On the southwest part of the WSRP profile, the Idaho-Oregon graben that separates the WSRP from the High Lava Plains was also modeled.

    We have characterized the natural immune responses to the 19-kDa domain of merozoite surface protein 1 in individuals from an area of western Kenya in which malaria is holoendemic. We used the three known natural variant forms of the yeast-expressed recombinant 19-kDa fragment that are referred to as the E-KNG, Q-KNG, and E-TSR antigens. T-cell proliferative responses in individuals older than 15 years and the profile of immunoglobulin G (IgG) antibody isotypes in individuals from 2 to 74 years old were determined. Positive proliferative responses to the Q-KNG antigen were observed for 54% of the individuals, and 37 and 35% of the individuals responded to the E-KNG and E-TSR constructs, respectively. Considerable heterogeneity in the T-cell proliferative responses to these three variant antigens was observed in different individuals, suggesting that the 19-kDa antigen may contain variant-specific T epitopes. Among responses of the different isotypes of the IgG antibody, IgG1 and IgG3 isotype responses were predominant, and the prevalence and levels of the responses increased with age. We also found that a higher level of IgG1 antibody response correlated with lower parasite density among young age groups, suggesting that IgG1 antibody response may play a role in protection against malaria. However, there was no correlation between the IgG3 antibody level and protection. Furthermore, we observed that although the natural antibodies cross-reacted with all three variant 19-kDa antigens, IgG3 antibodies in 12 plasma samples recognized only the E-KNG and Q-KNG constructs and not the E-TSR antigen. This result suggests that the fine specificity of IgG3 antibodies differentiates among variant-specific natural B-cell determinants in the second epidermal growth factor domain (KNG and TSR) of the antigen.

    Implementation of therapy for acute kidney injury (AKI) depends on successful prediction of individual patient prognosis. Clinical markers as serum creatinine (sCr) have limitations in sensitivity and early response. The aim of the study was to identify novel molecules in urine which show altered levels in response to AKI and investigate their value as predictors of recovery. Changes in the urinary proteome were here investigated in a cohort of 88 subjects (55 AKI patients and 33 healthy donors) grouped in discovery and validation independent cohorts. Patients’ urine was collected at three time points: within the first 48 h after diagnosis(T1), at 7 days of follow-up(T2) and at discharge of Nephrology(T3). Differential gel electrophoresis was performed and data were confirmed by Western blot (WB), liquid chromatography/mass spectrometry (LC-MS/MS) and enzyme-linked immunosorbent assay (ELISA). Retinol binding protein 4 (RBP4) and kininogen-1 (KNG1) were found significantly altered following AKI. RBP4 increased at T1, and progressively decreased towards normalization. Maintained decrease was observed for KNG1 from T1. Individual patient response along time revealed RBP4 responds to recovery earlier than sCr. In conclusion, KNG1 and RBP4 respond to AKI. By monitoring RBP4, patient’s recovery can be anticipated pointing to a role of RBP4 in prognosis evaluation. PMID:26792617

    Understanding gene function is far easier when tools are available to engineer a bacterial strain lacking a specific gene and phenotypically compare its behavior with the corresponding parental strain. Such mutants could be selected randomly, either by natural selection under particular stress conditions or by random mutagenesis using transposon delivery as described elsewhere in this book. However, with the advent of the genomic era there are now hundreds of bacterial genomes whose sequence is available, and thus, genes can be identified, chosen, and strategies designed to specifically inactivate them. This can be done by using suicide plasmids and is most convenient when the bacterium of interest is easily amenable to genetic manipulation. The method presented here will describe the use of a suicide vector, pKNG101, which allows the selection of a double-recombination event. The first event results in the integration of the pKNG101 derivative carrying the "mutator" fragment onto the chromosome, and could be selected on plates containing appropriate antibiotics. The pKNG101 carries the sacB gene, which induces death when cells are grown on sucrose. Growth on sucrose plates will thus select the second homologous recombination event, which results in removing the plasmid backbone and leaving behind the mutated target gene. This method has been widely used over the last 20 years to inactivate genes in a wide range of gram-negative bacteria and in particular in Pseudomonas aeruginosa. PMID:24818930

    ROR1 is a receptor tyrosine kinase (RTK) recently identified to be overexpressed at the gene and protein levels in chronic lymphocytic leukemia (CLL). Monoclonal antibodies (MAbs) against RTKs have been successfully applied for therapy of solid tumors. We generated five MAbs against the Ig (n = 1), cysteine-rich (CRD) (n = 2) and kringle (KNG) (n = 2) domains, respectively, of the extracellular part of ROR1. All CLL patients (n = 20) expressed ROR1 on the surface of the leukemic cells. A significantly higher frequency of ROR1 expression was found in patients with progressive versus non-progressive disease, and in those with unmutated versus mutated IgVH genes. All five MAbs alone induced apoptosis in the absence of complement or added effector cells (Annexin-V and MTT, as well as cleavage of poly-(ADP ribose)-polymerase, caspase-8 and caspase-9) of CLL cells but not of normal B cells. Most effective were MAbs against CRD and KNG, significantly superior to rituximab (P < 0.005). Cross-linking of anti-ROR1 MAbs using the F(ab')(2) fragments of anti-Fc antibodies significantly augmented apoptosis. Two of the MAbs induced complement-dependent cytotoxicity (CDC) similar to that of rituximab and one anti-ROR1 MAb (KNG) (IgG1) showed killing activity by antibody-dependent cellular cytotoxicity. The identified ROR1 epitopes may provide a basis for generating human ROR1 MAbs for therapy. PMID:22289919

  12. Are bursts of green leaf volatile emissions from plants following light to dark transitions associated with de-novo biosynthesis of free fatty acids and not stress-induced membrane degradation?

    Green Leaf Volatiles (GLVs) are a diverse group of fatty acid-derived Volatile Organic Compounds (VOCs) emitted by all plants. These GLVs are involved in a wide variety of stress-related biological functions, as well as the formation of secondary organic aerosols and ozone in the troposphere. To date, GLV emissions have primarily been associated with acute stress responses wherein fatty acids are released from plant membranes and enzymatically oxidized to GLVs via the lipoxygenase pathway. However the biochemical role of these gases within unwounded plants has remained unknown so far. Recently, GLV emissions were reported following light-dark transitions and were hypothesized to also be related to a mechanical stress response (i.e. leaf cutting). However in this study we show that GLV emissions from mesquite trees have a separate biochemical pathway for their production that is unrelated to stress. GLV emission rates following light-dark transitions were quantified from young and mature Mesquite branches. It was found that young branches had very high photosynthetic rates and displayed strong bursts of a wide array of GLVs following darkening, while mature branches had much lower photosynthetic rates showed much weaker or no bursts. This is interesting because neither the mature nor the juvenile plants were subjected to any type of stress during measurement. Moreover, the older plant samples (which had the lower emissions) were collected by clipping branches from a tree and re-clipping their stems under water. Given what has previously been established concerning the relationship of GLV emissions to mechanical stress, one would expect these older branches to have higher emissions than their juvenile counterparts rather than lower emissions. We speculate that the emission of GLVs during light-dark transitions is not the result of a stress response, but rather the result of rapid de-novo fatty acid biosynthesis occurring in chloroplasts of young branches fed by a direct connection to recently assimilated carbon in the light and the sudden activation of lipoxygenase enzymes upon darkening. These findings have important implications for understanding fatty acid metabolism in plants and the impact of GLV emissions on air quality and climate. If this link between GLV emissions and fatty acid biosynthesis can be well characterized for other plants, it could hypothetically be used as a diagnostic tool to monitor the health of agricultural crops or monitor the rate of plant growth. Furthermore, by understanding and quantifying the emission of these reactive compounds from plants one could begin to incorporate their presence into meteorological or climatic models.

    The epidemic of pulmonary tuberculosis (TB), especially multidrug-resistance tuberculosis (MDR-TB) presented a major challenge for TB treatment today. We performed iTRAQ labeling coupled with two-dimensional liquid chromatography-tandem mass spectrometry (2D LC-MS/MS) and Solexa sequencing among MDR-TB patients, drug-sensitive tuberculosis (DS-TB) patients, and healthy controls. A total of 50 differentially expressed proteins and 43 differentially expressed miRNAs (fold change >1.50 or <0.60, P<0.05) were identified in the MDR-TB patients compared to both DS-TB patients and healthy controls. We found that 22.00% of differentially expressed proteins and 32.56% of differentially expressed miRNAs were related, and could construct a network mainly in complement and coagulation cascades. Significant differences in CD44 antigen (CD44), coagulation factor XI (F11), kininogen-1 (KNG1), miR-4433b-5p, miR-424-5p, and miR-199b-5p were found among MDR-TB patients, DS-TB patients and healthy controls (P<0.05) by enzyme-linked immunosorbent assay (ELISA) and SYBR green qRT-PCR validation. A strong negative correlation, consistent with the target gene prediction, was found between miR-199b-5p and KNG1 (r=-0.232, P=0.017). Moreover, we established the MDR-TB diagnostic model based on five biomarkers (CD44, KNG1, miR-4433b-5p, miR-424-5p, and miR-199b-5p). Our study proposes potential biomarkers for MDR-TB diagnosis, and also provides a new experimental basis to understand the pathogenesis of MDR-TB. PMID:26884721

  14. Involvement of B2 Receptor in Bradykinin-Induced Proliferation and Proinflammatory Effects in Human Nasal Mucosa-Derived Fibroblasts Isolated from Chronic Rhinosinusitis Patients

    PubMed Central

    2015-01-01

    Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the sinonasal mucosa either accompanied by polyp formation (CRSwNP) or without polyps (CRSsNP). CRSsNP accounts for the majority of CRS cases and is characterized by fibrosis and neutrophilic inflammation. However, the pathogenesis of CRS, especially CRSsNP, remains unclear. Immunohistochemistry of CRSsNP specimens in the present study showed that the submucosa, perivascular areas, and the mucous glands were abundant in fibroblasts. Therefore, we investigated the effects bradykinin (BK), an autacoid known to participate in inflammation, on human CRSsNP nasal mucosa-derived fibroblasts (NMDFs). BK increased CXCL1 and -8 secretion and mRNA expression with EC50 ranging from 0.15~0.35 μM. Moreover, BK enhanced cell proliferation and upregulated the expressions of proinflammatory molecules, including cell adhesion molecules (CAMs) and cyclooxygenase (COX)-1 and -2. These functionally caused an increase in monocyte adhesion to fibroblast monolayer. Using pharmacological intervention and BKR siRNA knockdown, we demonstrated that the BK-induced CXCL chemokine release, cell proliferation and COX and CAM expressions were mainly through the B2 receptor (B2R). Accordingly, the B2R was preferentially expressed in the NMDFs than B1R. The B2R was highly expressed in the CRSsNP than the control specimens, while the B1R and kininogen (KNG)/BK expression slightly increased in the CRSsNP mucosa. Collectively, we report here for the first time that fibroblasts, KNG/BK, and BKRs are overexpressed in CRSsNP mucosa and BK upregulates chemokine expression, proliferation, and proinflammatory molecule expression in NMDFs via B2R activation, which lead to a functional increase in monocyte-fibroblast interaction. Our findings reveal a critical role of fibroblast, KNG/BK, and BKRs in the development of CRSsNP. PMID:25970620

  15. Challenge theme 4: people in the Borderlands: Chapter 6 in United States--Mexican Borderlands--facing tomorrow’s challenges through USGS science

    USGS Publications Warehouse

    Norman, Laura M.; Shuster, Rudy M.; Parcher, Jean W.

    2013-01-01

    The management of shared resources in the United States–Mexican border region requires cooperation from the people of both countries to assess and understand their relation to the environment. Society is dependent on the long-term healthy functioning of ecosystems and their ability to supply food and raw materials. Likewise, resources and services obtained from nature could be used efficiently within the society. A more equitable distribution of costs and benefits related to goods and services can lead to fewer tensions and a higher quality of life for all the people in the Borderlands. Urban development, background contamination from mineral ore deposits, irrigation, sewage effluent, and even global climate change all have the potential to alter the stability of the fragile systems in the Borderlands (Brady and others, 2001, 2002; Norman, 2007, 2010; Gu and others, 2008; Norman, Gray, and others, 2008; Norman, Hirsch, and Ward, 2008; Norman, Callegary, and others, 2010; Norman, Huth, and others, 2010; Norman, Levick, and others, 2010; Norman, Tallent-Halsell, and others, 2010; Norman, Villarreal, and others 2012). Social efficiency means that because resources should be used where they are needed most, they should be distributed proportionally among human societies and individuals (Azar and others, 1996). Despite the critical role natural resources play in maintaining human and environmental health, current knowledge of the manner in which natural and human-caused forces interact to limit these resources—including their quality and quantity (such as through spatiotemporal changes in precipitation, evapotranspiration, pumping of groundwater, and release of contaminants)—is inadequate. The U.S. Geological Survey (USGS) is trying to understand the relation between changing landscapes, changing demographics, and a changing climate in the Borderlands while the environmental, economic, and societal issues continue to be intertwined between the two nations.

    PubMed

    Jiménez, L; Serrano, L; Rodríguez, A; Ferrer, A

    2009-02-01

    The AOpAZRP bleaching sequence (A is an acid treatment, Op an oxygen and peroxide stage, Z an ozone stage, R a reductive treatment and P a peroxide stage) have been applied to oil palm empty fruit bunches (EFB) soda-anthraquinone and diethanolamine pulp. On similar Kappa numbers for the two types of pulp (14.2 and 17.3), paper from unbleached soda-anthraquinone pulp exhibited increased tensile index (25.8 Nm/g), stretch (2.35%), burst index (1.69 kN/g), tear index (0.50 mN m(2)/g) and brightness (60.6%) relative to paper for unbleached diethanolamine pulp; but the latter type of pulp exhibited higher viscosity (659 mL/g) than the former. Upon bleaching with the AOpAZRP sequence, diethanolamine pulp exhibited higher viscosity (783 mL/g), and the properties of the paper sheets were close to or even better to those from soda-anthraquinone pulp, namely: 22.2 vs 20.4 Nm/g tensile index, 1.30 vs 1.42 kN/g burst index, 0.71 vs 0.70 mN m(2)/g tear index and 71.3% vs 77.5% brightness. Therefore, the properties of paper from diethanolamine pulp evolved more favourably during bleaching than did those of paper from soda-anthraquinone pulp. PMID:18809321

  10. The choice of a name: "Dora" and Freud's relationship with Breuer.

    PubMed

    Decker, H S

    1982-01-01

    I have suggested that Freud's choice of the pseudonym Dora for his eighteen-year-old hysterical patient, Ida Bauer, was over-determined. Dora, it seems likely, was named not only after Freud's sister's nursemaid, as Freud himself explained, but also after Dora Breuer, Josef Breuer's youngest daughter. This theory is based on an examination of the similarities in the lives and symptoms of Anna O. (Breuer's famous hysterical patient of 1880-1882) and Dora; on an analysis of the transferences and countertransferences in the cases of these two young women; and on evidences of the persistent significance of Josef Breuer in Freud's life after 1895. These specific inquiries also call attention to the nature of hysteria at the end of the nineteenth century and to the ever-present complexities of the physician-patient relationship. PMID:6926991

    1994-01-01

    Histidine-rich glycoprotein (HRG) belongs to the cystatin superfamily and appears to be a potential risk factor for thrombosis. An increased prevalence of elevated HRG plasma levels in patients with venous thrombosis and families with thrombophilia has been reported. It is interesting to note that the genes of four different members of the cystatin superfamily are located on the distal section of the long arm of chromosome 3: Stefin A (STF1) on 3q21, Kininogen (KNG) on 3q26-qter, [alpha]-2-HS-glycoprotein (AHSG) on 3q27-q28, and HRG on 3q21-qter. To further investigate the evolutionary relationship between HRG and members of the cystatin superfamily, the authors isolated a cosmid that was used to refine the chromosomal localization of HRG by in situ hybridization. In addition, they used a dinucleotide repeat polymorphism to localize HRG on the linkage map of chromosome 3q. 10 refs., 2 figs.

  12. Vegetation and Climate history of Franz Jozef Land Archipelago in the Late Holocene according pollen data

    2015-04-01

    The archipelago Franz-Josef Land is situated in the Arctic Ocean (80°40' N, 54°50'E). It is one of the important areas for arctic research due to organization of Russian Arctic National Park there. Therefore, an interest to the environmental history of this territory grows up and any new data might have a high value. However, geographical remoteness of the archipelago is the reason why there are not much work has been done up to date. .A focus of our researches is vegetation and climate reconstruction during the Late Holocene history according pollen data. In frame of studying of the Franz Josef Land during complex expedition of Russian Arctic National Park on the islands geomorphological and botanical researches was occurred. Nowadays the typical island of archipelago presents the ice cap and glacier-free marine terraces of 35 m high at maximum, where solifluction and permafrost are developed. The archipelago has a maritime Arctic climate. Vegetation of archipelago Franz-Josef Land presents the northern type of Polar Desert. It includes 57 species of vascular plants (Poaceae, Juncaceae, Caryophyllaceae, Brassicaceae, Saxifragaceae etc). We studied the peat core from the southern part of Majbel Island, in the archipelago Franz Josef Land. More than a half of the island is covered by glacier. The core was sampled at the inner margin of ice-free high marine terrace, near the southern slope of bedrock hill. We received preliminary pollen data and radiocarbon data 3010±80 C14 y.a. at the bottom. The pollen concentration is low, but we manage to make some reconstructions of vegetation and climate. For correct interpretation of our results, we used surface samples from different islands of archipelago (Jackson, Hooker, Greely, Alexsandra land, Yeva-Liv, Appolonov, Georg land, Kane, Bell). Subrecent spectra include species presented in flora of region, but also those which are not founded at this region in this time.

    Contrary to Newton's concept of inertia, general relativity predicts an influence of rotating matter on the structure of space and time. Anticipated by Ernst Mach, effects of this type have first been derived by Hans Thirring and Josef Lense. Almost ninety years later, we face their experimental verification. An even more dramatic scenario is provided by Kurt Gödel's cosmological model, in which nearby observers rotate with respect to each other and are free to travel to their own past.

    New results from seismic monitoring in the Euro-Arctic region, including the seismicity of Gakkel Ridge and the Barents-Kara Sea shelf, are presented. The data used were obtained from the Arkhan-gelsk seismic network. The role of island-based seismic stations, in particular, those in Franz Josef Land, in the monitoring network is discussed. The possibility of specifying the nature of seismicity by waveform spectral-temporal analysis, even in the case of a single station, is considered.

  15. Relationship between the gene polymorphisms of kallikrein-kinin system and Alzheimer’s disease in a Hunan Han Chinese population

    Deng, Yanyao; Hou, Deren; Tian, Mi; Li, Wei; Feng, Xialu; Yu, Zhuling

    2015-01-01

    This study aimed to determine the connection between polymorphisms of kallikrein kinin system including KLK1 (rs5516), KNG1 (rs710446, rs2304456) and ACE (rs4291, rs4309, rs4343) and late-onset Alzheimer’s disease (LOAD). The research was conducted as a case-control study, comprising 201 AD patients in the AD group, and 257 healthy subjects as the control group. PCR amplification and matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) were used to detect the six polymorphisms (rs5516 in KLK1; rs710446, rs2304456 in KNG1; rs4291, rs4309, rs4343 in ACE) from both groups. No statistically significant difference was found between the genotype and allelotype distributions of rs5516, rs710446, rs2304456, rs4291 and rs4343 (P>0.05). The differences between the genotype and allelotype distributions of the rs4309 were statistically significant (P<0.05). Haplotype analysis confirmed the existence of three haplotypes (AG, AT, GT) composed of rs710446/rs2304456, and six haplotypes (ATA, ACA, TCA, TCG, TTA, TTG) composed of rs4291/rs4309/rs4343, among which the distribution of ATA, ACA, TCA between the two groups was statistically significant difference (P<0.05). Our study showed that the polymorphisms of rs5516, rs710446, rs2304456, rs4291 and rs4343 is not related to the incidence of LOAD. The polymorphisms of rs4309 may be related to LOAD, as well as ATA, ACA, and TCA haplotype composed of rs4291/rs4309/rs4343. PMID:26884824

    Cryophilic algae thrive in liquid water within snow and ice in alpine and polar regions worldwide. Blooms of these algae lower albedo (reflection of sunlight), thereby altering melting patterns (Kohshima, Seko & Yoshimura, 1993; Lutz et al., 2014; Thomas & Duval, 1995). Here metagenomic DNA analysis and satellite imaging were used to investigate red snow in Franz Josef Land in the Russian Arctic. Franz Josef Land red snow metagenomes confirmed that the communities are composed of the autotroph Chlamydomonas nivalis that is supporting a complex viral and heterotrophic bacterial community. Comparisons with white snow communities from other sites suggest that white snow and ice are initially colonized by fungal-dominated communities and then succeeded by the more complex C. nivalis-heterotroph red snow. Satellite image analysis showed that red snow covers up to 80% of the surface of snow and ice fields in Franz Josef Land and globally. Together these results show that C. nivalis supports a local food web that is on the rise as temperatures warm, with potential widespread impacts on alpine and polar environments worldwide.

  3. Arctic warming: nonlinear impacts of sea-ice and glacier melt on seabird foraging.

    Arctic climate change has profound impacts on the cryosphere, notably via shrinking sea-ice cover and retreating glaciers, and it is essential to evaluate and forecast the ecological consequences of such changes. We studied zooplankton-feeding little auks (Alle alle), a key sentinel species of the Arctic, at their northernmost breeding site in Franz-Josef Land (80°N), Russian Arctic. We tested the hypothesis that little auks still benefit from pristine arctic environmental conditions in this remote area. To this end, we analysed remote sensing data on sea-ice and coastal glacier dynamics collected in our study area across 1979-2013. Further, we recorded little auk foraging behaviour using miniature electronic tags attached to the birds in the summer of 2013, and compared it with similar data collected at three localities across the Atlantic Arctic. We also compared current and historical data on Franz-Josef Land little auk diet, morphometrics and chick growth curves. Our analyses reveal that summer sea-ice retreated markedly during the last decade, leaving the Franz-Josef Land archipelago virtually sea-ice free each summer since 2005. This had a profound impact on little auk foraging, which lost their sea-ice-associated prey. Concomitantly, large coastal glaciers retreated rapidly, releasing large volumes of melt water. Zooplankton is stunned by cold and osmotic shock at the boundary between glacier melt and coastal waters, creating new foraging hotspots for little auks. Birds therefore switched from foraging at distant ice-edge localities, to highly profitable feeding at glacier melt-water fronts within <5 km of their breeding site. Through this behavioural plasticity, little auks maintained their chick growth rates, but showed a 4% decrease in adult body mass. Our study demonstrates that arctic cryosphere changes may have antagonistic ecological consequences on coastal trophic flow. Such nonlinear responses complicate modelling exercises of current and future

    The final traumatic event recalled by Anna O. during her treatment with Josef Breuer was a terrifying hallucination she once had of a black snake attacking her ailing father. This event has been variously interpreted as indicating an underlying psychodynamic conflict, as a temporal lobe seizure, and as an hypnotic confabulation. We argue, however, that the hallucination--during which Anna O.'s arm was reportedly "asleep" due to nerve blockage--was probably a sleep paralysis nightmare. Sleep paralysis nightmares continue to be overlooked or misdiagnosed in clinical practice, and, in recent years, have been implicated in the controversy surrounding memories of trauma and sexual abuse.

    A detailed gravity field map of the mid Arctic Ocean, spreading ridge system was produced on the basis of ERS-1 satellite altimetry data. Areas of special concern, the Barents and Kara Seas, and areas surrounding the islands of Svalbard, Frans Josef Land and Novoya Zemlya are reviewed. ERS-1 altimetry covers unique Arctic and Antarctic latitudes above 72 degrees. Before ERS-1 it was not possible to study these areas with satellite altimetry. Gravity field solutions for the Barents Sea, portions of the Arctic Ocean and the Norwegian sea are shown. The largest gravity anomalies occur along the Greenland fracture zone as well as along transform faults near Svalbard.

    The leaf extract of Tamarindus indica L. (T. indica) had been reported to possess high phenolic content and showed high antioxidant activities. In this study, the effects of the antioxidant-rich leaf extract of the T. indica on lipid peroxidation, antioxidant enzyme activities, H2O2-induced ROS production and gene expression patterns were investigated in liver HepG2 cells. Lipid peroxidation and ROS production were inhibited and the activity of antioxidant enzymes superoxide dismutase, catalase and glutathione peroxidase was enhanced when the cells were treated with the antioxidant-rich leaf extract. cDNA microarray analysis revealed that 207 genes were significantly regulated by at least 1.5-fold (p < 0.05) in cells treated with the antioxidant-rich leaf extract. The expression of KNG1, SERPINC1, SERPIND1, SERPINE1, FGG, FGA, MVK, DHCR24, CYP24A1, ALDH6A1, EPHX1 and LEAP2 were amongst the highly regulated. When the significantly regulated genes were analyzed using Ingenuity Pathway Analysis software, “Lipid Metabolism, Small Molecule Biochemistry, Hematological Disease” was the top biological network affected by the leaf extract, with a score of 36. The top predicted canonical pathway affected by the leaf extract was the coagulation system (P < 2.80 × 10−6) followed by the superpathway of cholesterol biosynthesis (P < 2.17 × 10−4), intrinsic prothrombin pathway (P < 2.92 × 10−4), Immune Protection/Antimicrobial Response (P < 2.28 × 10−3) and xenobiotic metabolism signaling (P < 2.41 × 10−3). The antioxidant-rich leaf extract of T. indica also altered the expression of proteins that are involved in the Coagulation System and the Intrinsic Prothrombin Activation Pathway (KNG1, SERPINE1, FGG), Superpathway of Cholesterol Biosynthesis (MVK), Immune protection/antimicrobial response (IFNGR1, LEAP2, ANXA3 and MX1) and Xenobiotic Metabolism Signaling (ALDH6A1, ADH6). In conclusion, the antioxidant-rich leaf extract of T. indica inhibited lipid

    Background: Lung cancer has become the leading cause of death in many regions. Carcinogenesis is caused by the stepwise accumulation of genetic and chromosomal changes. The aim of this study was to investigate the chromosome and gene alterations in the human lung adenocarcinoma cell line OM. Methods: We used Giemsa banding and multiplex fluorescence in situ hybridization focusing on the human lung adenocarcinoma cell line OM to analyze its chromosome alterations. In addition, the gains and losses in the specific chromosome regions were identified by comparative genomic hybridization (CGH) and the amplifications of cancer-related genes were also detected by polymerase chain reaction (PCR). Results: We identified a large number of chromosomal numerical alterations on all chromosomes except chromosome X and 19. Chromosome 10 is the most frequently involved in translocations with six different interchromosomal translocations. CGH revealed the gains on chromosome regions of 3q25.3-28, 5p13, 12q22-23.24, and the losses on 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33 and 17p13.1-13.3. And PCR showed the amplification of genes: Membrane metalloendopeptidase (MME), sucrase-isomaltase (SI), butyrylcholinesterase (BCHE), and kininogen (KNG). Conclusions: The lung adenocarcinoma cell line OM exhibited multiple complex karyotypes, and chromosome 10 was frequently involved in chromosomal translocation, which may play key roles in tumorigenesis. We speculated that the oncogenes may be located at 3q25.3-28, 5p13, 12q22-23.24, while tumor suppressor genes may exist in 3p25-26, 6p25, 6q26-27, 7q34-36, 8p22-23, 9p21-24, 10q25-26.3, 12p13.31-13.33, and 17p13.1-13.3. Moreover, at least four genes (MME, SI, BCHE, and KNG) may be involved in the human lung adenocarcinoma cell line OM. PMID:26879013

    What would you call the next generation of radar for severe weather prediction? NEXRAD, of course. A prototype for the new system was recently completed in Norman, Okla., and by the early 1990s up to 195 stations around the United States will be tracking dangerous weather and sending faster, more accurate, and more detailed warnings to the public.NEXRAD is being built for the Departments of Commerce, Transportation, and Defense by the Unisys Corporation under a $450 million contract signed in December 1987. Th e system will be used by the National Weather Service, the Federal Aviation Administration (FAA), and the U.S. Air Force and Navy. The NEXRAD radar tower in Norman is expected to be operational in October.

    2016-11-01

    Householders' behaviour with their home heating systems is a considerable contributor to domestic energy consumption. To create a design specification for the 'scaffolding' needed for sustainable behaviour with home heating controls, Norman's (1986) Gulf of Execution and Evaluation was applied to the home heating system. A Home Heating Design Model (DM) was produced with a home heating expert. Norman's (1986) 7 Stages of Activity were considered to derive a Compatible User Mental Model (CUMM) of a typical Heating System. Considerable variation in the concepts needed at each stage was found. Elements that could be derived from the DM supported stages relating to action specification, execution, perception and interpretation, but many are not communicated in the design of typical heating controls. Stages relating to goals, intentions and evaluation required concepts beyond the DM. A systems view that tackles design for sustainable behaviour from a variety of levels is needed. PMID:27062135

    Le Norman Energy Company conducted research on field application of alkaline-surfactant-polymer (ASP) flooding as a part of the U.S. Department of Energy's plan to maximize the production of our domestic oil resources. In addition to having substantial technical merit, the process uses chemicals that are environmentally acceptable. Le Norman's field project is located in the Sho-Vel-Tum (OK) oil field, which was a major producer of crude oil in past years, but has since been extensively waterflooded. This reservoir in this portion of the field is typical of many shallow reservoirs in the Oklahoma-Kansas area and is a good demonstration site for that area. The pay zones are located approximately 700 ft. deep, and this project is the shallowest field test for ASP flooding.

    Permafrost soils contain approximately1700 Pg of carbon (C), twice the amount of C in the atmosphere. Temperatures in higher latitudes are increasing, inducing permafrost thaw and subsequent microbial decomposition of previously frozen C. This process is one of the most likely positive feedbacks to climate change. Understanding the temperature sensitivity (Q10) and dynamics of SOM decomposition under warming is essential to predict the future state of the earth - climate system. Alaskan tundra soils were exposed to two winter warming (WW) seasons in the field, which warmed the soils by 4°C to 40 cm depth. Soils were obtained from three depths (0 - 15, 15 - 25 and 45 - 55 cm) and differed in initial amounts of labile and recalcitrant C. Soils were incubated in the lab under aerobic conditions, at 15 and 25°C over 365 days. Q10 was estimated at 14, 100 & 280 days of incubation (DOI); C fluxes were measured periodically and dynamics of SOM decomposition (C pool sizes and decay rates) were estimated by fitting a two pool C model to cumulative respired C (Ccum, mgC/ginitialC). After two WW seasons, initial C content tended to decrease through the soil profile and C:N ratio was significantly decreased in the top 15 cm. After one year of incubation, Ccum was twice as high at 25°C as at 15°C and significantly decreased with depth. No significant WW field treatment was detected, although Ccum tended to be lower in warmed soils. Labile C accounted for up to 5% of initial soil C content in the top 15 cm and decreased with depth. Soils exposed to WW had smaller labile C pools, and higher labile C decay rates in the top 25 cm. Q10 significantly decreased with time and depth as labile pool decreased, especially for WW. This decrease with time indicates a lower temperature sensitivity of the most recalcitrant C pool. The deepest WW soil layer, where warming was more pronounced, had significantly lower Q10 compared to control soils at the same depth. After two seasons, the warming treatment affected decomposition by reducing labile C pools and increasing its decay rates. Warming also reduced temperature sensitivity, showing acclimation of the most recalcitrant C pool in the tundra ecosystem.

    This article emphasizes the critical need for information specifically regarding the topic of retained sucking behaviors. The study aimed to confirm results provided by Van Norman of 723 subjects in 1997. Parent surveys were collected on 441 subjects who received an orofacial myofunctional treatment program provided by one certified orofacial myologist. Results of this study do confirm that retained digit sucking behavior may be addressed successfully and expediently by a program based on positive behavior modification techniques. PMID:23362602

    The economic recession, the mounting costs of medical technology, and the weakening of public support for welfare state ideals have led to philosophical qualification of the right of equal access to health care by writers like Norman Daniels and Lawrence Stern. Green rejects their arguments and reiterates the claim that a Rawlsian theory of justice provides an appropriate way of thinking about the right to health care, which should be treated on a par with basic civil liberties.

    Geographical variation of organochlorine pesticides (OCPs) was studied in blood samples from 90 adult female polar bear (Ursus maritimus) from Svalbard, Franz Josef Land, Kara Sea, East-Siberian Sea and Chukchi Sea. In all regions, oxychlordane was the dominant OCP. Regional differences in mean levels of HCB, oxychlordane, trans-nonachlor, ??-HCH, ??-HCH and p,p???-DDE were found. The highest levels of oxychlordane, trans-nonachlor and DDE were found in polar bears from Franz Josef Land and Kara Sea. HCB level was lowest in polar bears from Svalbard. Polar bears from Chukchi Sea had the highest level of ??- and ??-HCH. The lowest ??-HCH concentration was found in bears from Kara Sea. In all the bears, ???HCHs was dominated by ??-HCH. The geographical variation in OCP levels and pattern may suggest regional differences in pollution sources and different feeding habits in the different regions. Polar bears from the Western Russian Arctic were exposed to higher levels of chlordanes and p,p???-DDE than polar bears from locations westwards and eastwards from this region. This may imply the presence of a significant pollution source in the Russian Arctic area. The study suggests that the western Russian Arctic is the most contaminated region of the Arctic and warrants further research. ?? 2002 Elsevier Science B.V. All rights reserved.

    SUMMARY The extreme anterior domain (EAD) is a conserved embryonic region that includes the presumptive mouth. We show that the Kinin-Kallikrein pathway is active in the EAD and necessary for craniofacial development in Xenopus and zebrafish. The mouth failed to form and neural crest (NC) development and migration was abnormal after loss of function (LOF) in the pathway genes kng, encoding Bradykinin (xBdk), carboxypeptidase-N (cpn) that cleaves Bradykinin and neuronal nitric oxide synthase. Consistent with a role for nitric oxide (NO) in face formation, endogenous NO levels declined after LOF in pathway genes but these were restored and a normal face formed after medial implantation of xBdk-beads into LOF embryos. Facial transplants demonstrated that Cpn function from within the EAD is necessary for migration of first arch cranial NC into the face and to promote mouth opening. The study identifies the EAD as an essential craniofacial organizer acting through Kinin-Kallikrein signaling. PMID:25043181

    The influence of soda-anthraquinone pulping variables (temperature, time and soda concentration) and beating (number of PFI beating revolution) of palm oil empty fruit bunches (EFB) on the resulting paper sheets was studied, with a view to identifying the optimum operating conditions. Equations were derived that reproduced the properties of the paper sheets with errors less than 10-12% in 90-95% of cases. An optimum compromise was found as regards operating conditions (15% soda, 170 degrees C, 70 min and 2400 number of PFI beating revolutions) that provided paper properties departing by less than 12% from their optimum values (59.63 Nm/g tensile index, 4.48% stretch, 4.17 kN/g burst index and 7.20 m Nm(2)/g tear index), and a beating grade of 47.5 degrees SR, acceptable to obtain paper sheets. Because these conditions involve a lower soda, temperature, time and beating than those required to maximize the studied paper properties, they can save chemical reagents, energy and immobilized capital for industrial facilities. On the other hand, the stretch properties of these pulp beaten are higher than those of others non-wood pulps, as wheat straw and olive wood. PMID:18815028

    Oil palm empty fruit bunches were used as an alternative raw material to obtain cellulosic pulp. Pulping was done by using high-boiling point organic solvents of decreased polluting power relative to classical (Kraft, sulphite) solvents but affording operation at similar pressure levels. The holocellulose, alpha-cellulose and lignin contents of oil palm empty fruit bunches (viz. 66.97%, 47.91% and 24.45%, respectively) are similar to those of some woody raw materials such as pine and eucalyptus, and various non-wood materials including olive tree prunings, wheat straw and sunflower stalks. Pulping tests were conducted by using ethyleneglycol, diethyleneglycol, ethanolamine and diethanolamine under two different sets of operating conditions, namely: (a) a 70% solvent concentration, 170 degrees C and 90 min; and (b) 80% solvent, 180 degrees C and 150 min. The solid/liquid ratio was six in both cases. The amine solvents were found to provide pulp with better properties than did the glycol solvents. Ethanolamine pulp exhibited the best viscosity and drainage index (viz. 636 mL/g and 17 degrees SR, respectively), and paper made from it the best breaking length (1709 m), stretch (1.95%), burst index (0.98 kN/g) and tear index (0.33 mNm(2)/g). Operating costs can be reduced by using milder conditions, which provide similar results. In any case, the amines are to be preferred to the glycols as solvents for this purpose. PMID:17507215

    Background Periodontitis is one of the most common oral diseases associated with the host’s immune response against periodontopathogenic infection. Failure to accurately diagnose the stage of periodontitis has limited the ability to predict disease status. Therefore, we aimed to look for reliable diagnostic markers for detection or differentiation of early stage periodontitis using the immunoprotemic approach. Method In the present study, patient serum samples from four distinct stages of periodontitis (i.e., mild chronic, moderate chronic, severe chronic, and aggressive) and healthy controls were subjected to two-dimensional gel electrophoresis (2-DE), followed by silver staining. Notably, we consistently identified 14 protein clusters in the sera of patients and normal controls. Results Overall, we found that protein levels were comparable between patients and controls, with the exception of the clusters corresponding to A1AT, HP, IGKC and KNG1 (p < 0.05). In addition, the immunogenicity of these proteins was analysed via immunoblotting, which revealed differential profiles for periodontal disease and controls. For this reason, IgM obtained from severe chronic periodontitis (CP) sera could be employed as a suitable autoantibody for the detection of periodontitis. Discussion Taken together, the present study suggests that differentially expressed host immune response proteins could be used as potential biomarkers for screening periodontitis. Future studies exploring the diagnostic potential of such factors are warranted.

    A normalized design was used to examine the influence of independent variables (alcohol concentration, cooking time and temperature) in the catalytic soda-ethanol pulping of rice straw on various mechanical properties (breaking length, burst, tear index and folding endurance) of paper sheets obtained from each pulping process. An equation of each dependent variable as a function of cooking variables (independent variables) was obtained by multiple non-linear regression using the least square method by MATLAB software for developing of empirical models. The ranges of alcohol concentration, cooking time and temperature were 40-65% (w/w), 150-180 min and 195-210 degrees C, respectively. Three-dimensional graphs of dependent variables were also plotted versus independent variables. The optimum values of breaking length, burst and tear index and folding endurance were 4683.7 (m), 30.99 (kN/g), 376.93 (mN m2/g) and 27.31, respectively. However, short cooking time (150 min), high ethanol concentration (65%) and high temperature (210 degrees C) could be used to produce papers with suitable burst and tear index. However, for papers with best breaking length and folding endurance low temperature (195 degrees C) was desirable. Differences between optimum values of dependent variables obtained by normalized design and experimental data were less than 20%. PMID:14643987

    Injection with natural compounds is an important method in the application of natural medicine, but its adverse drug reactions (ADRs) occur frequently, particularly the anaphylactoid reaction, which accounts for more than 77% of all reactions and has become a serious threat to public health. Here, the Xuesaitong injection (XSTI) was employed as an example to elucidate its anaphylactoid mechanism and look for potential biomarkers to assay the anaphylactoid reaction of herbal medicine injection by proteomics and metabolomics. These results disclosed that 13 differential proteins and 28 metabolites, which were further approved using the ELISA method and reference standards, respectively, were suggested as potential biomarkers to examine the anaphylactoid mechanism. The up-regulated expression of Gpx1, Sc5b9, C4d and down-regulated expression of F12, Kng1, C2 and C6 revealed that the XSTI-induced anaphylactoid reaction occurs via direct stimulation, complement and the kallikrein-kinin pathway. In addition, substances that induce an anaphylactoid effect include histamine, LTB4, uric acid and other drugs, which have been confirmed to be involved in arginine and proline metabolism, histidine metabolism, arachidonic acid metabolism purine metabolism and the TCA cycle. Furthermore, separation experiments have indicated that 10-kDa molecules of XSTI are the main allergenic factor inducing an anaphylactoid reaction. PMID:26372445

    Maternal nutrition can affect development, leading to long-term effects on the health of offspring. The most common outcome is programmed hypertension. We examined whether alterations in renal transcriptome are responsible for generating programmed hypertension among four different models using next-generation RNA sequencing (NGS) technology. Pregnant Sprague-Dawley rats received 50% caloric restriction (CR), intraperitoneal injection of 45 mg/kg streptozotocin, 60% high-fructose (HF) diet, or 1% NaCl in drinking water to conduct CR, diabetes, HF, or high-salt models, respectively. All four models induced programmed hypertension in adult male offspring. We observed 16 shared genes in a two-week-old kidney among four different models. The identified differential expressed genes (DEGs) that are related to the regulation of blood pressure included Adrb3, Alb, Apoe, Calca, Kng1, Adm2, Guca2b, Hba2, Hba-a2, and Ppara. The peroxisome proliferator-activated receptor (PPAR) signaling pathway and glutathione metabolism pathway were shared by the CR, diabetes, and HF models. Conclusively, a variety of maternal nutritional insults induced the same phenotype—programmed hypertension with differential alterations of renal transcriptome in adult male offspring. The roles of DEGs identified by the NGS in this study deserve further clarification to develop ideal maternal dietary interventions and thus spare the next generations from the burden of hypertension.

    Activated partial thromboplastin time (aPTT) is an important routine measure of intrinsic blood coagulation. Addition of activated protein C (APC) to the aPTT test to produce a ratio, provides one measure of APC resistance. The associations of some genetic mutations (eg, factor V Leiden) with these measures are established, but associations of other genetic variations remain to be established. The objective of this work was to test for association between genetic variants and blood coagulation using a high-density genotyping array. Genetic association with aPTT and APC resistance was analysed using a focused genotyping array that tests approximately 50 000 single-nucleotide polymorphisms (SNPs) in nearly 2000 cardiovascular candidate genes, including coagulation pathway genes. Analyses were conducted on 2544 European origin women from the British Women's Heart and Health Study. We confirm associations with aPTT at the coagulation factor XII (F12)/G protein-coupled receptor kinase 6 (GRK6) and kininogen 1 (KNG1)/histidine-rich glycoprotein (HRG) loci, and identify novel SNPs at the ABO locus and novel locus kallikrein B (KLKB1)/F11. In addition, we confirm association between APC resistance and factor V Leiden mutation, and identify novel SNP associations with APC resistance in the HRG and F5/solute carrier family 19 member 2 (SLC19A2) regions. In conclusion, variation at several genetic loci influences intrinsic blood coagulation as measured by both aPTT and APC resistance. PMID:23188048

Significant amounts of lignin precursors, commonly postulated to be the major source of DOM, were found only in trace quantities by thermochemolysis/gas chromatography/mass spectrometry of the Norman Landfill and Tomago Sand Bed hydrophobic DOM fractions. Electrospray/tandem mass spectrometry of the Tomago Sand Bed hydrophobic acid DOM found an ion series differing by 14 daltons, which is indicative of aliphatic and aryl-aliphatic polycarboxylic acids. The product obtained from ozonation of the resin acid, abietic acid, gave a similar ion series. Terpenoid precursors of DOM are postulated to be derived from resin acid paper sizing agents in the Norman Landfill, algal and bacterial terpenoids in the Colorado River and Anaheim Lake, and terrestrial plant terpenoids in the Tomago Sand Beds.

    Two piston cores from the Eurasian flank of Lomonosov Ridge near lat 88.9°N, long 140°E provide the first samples of bedrock from this high-standing trans-Arctic ridge. Core 94-PC27 sampled nonmarine siltstone similar in facies and age to uppermost Triassic to lower Lower Jurassic and mid– Lower Cretaceous beds in the 4 to > 5 km Mesozoic section on Franz Josef Land, on the outer Barents shelf. A ca. 250 Ma peak in the cumulative frequency curve of detrital zircons from the siltstone, dated by U- Th-Pb analysis, suggests a source in the post-tectonic syenites of northern Taymyr and nearby islands in the Kara Sea. Textural trends reported in the literature indicate that the Lower Jurassic nonmarine strata of Franz Josef Land coarsen to the southeast; this suggests the existence of a sedimentary system in which detrital zircons could be transported from the northern Taymyr Peninsula to the outer Barents shelf near the position of core 94-PC27 prior to opening of the Eurasia Basin. Correlation of the coaly siltstone in core 94-PC27 with part of the Mesozoic section on Franz Josef Land is compatible with the strong evidence from seafloor magnetic anomalies and bathymetry that Lomonosov Ridge is a continental fragment rifted from the Barents shelf during the Cenozoic. It also suggests that Lomonosov Ridge near the North Pole is underlain by a substantial section of unmetamorphosed Mesozoic marine and nonmarine sedimentary strata. Core 94-PC29 sampled cyclical deposits containing ice-rafted debris (IRD) overlying weakly consolidated laminated olive-black anoxic Neogene siltstone and mudstone with an average total organic carbon (TOC) of 4.1 wt%. The high TOC content of the mudstone indicates that during the Neogene, prior to the introduction of IRD into the Arctic seas about 3.3 Ma (early late Pliocene), the shallow waters of the central Arctic Ocean supported significant primary photosynthetic organic production near the North Pole. These deposits also contain fine

    The terminal moraine of the Franz Josef Glacier in New Zealand, known as the Waiho Loop, has been subject to intense scientific research since it was identified as potential evidence of a Southern Hemisphere Younger Dryas (~12000 yrs BP) event in the late 1980s and early 1990s. As a result, the large, arcuate moraine has been interpreted to indicate inter-hemispheric connectivity and synchronicity of climate change, and in turn has been inferred to indicate a major late-glacial cooling event in New Zealand. In recent times, it has been postulated that the Loop moraine may not reflect climate variation at all, but rather it may have been the result of a landslide sourced from the upper Franz Josef catchment due to its rock-avalanche-debris-dominated composition. New evidence from shallow seismic studies between the Loop and the range front (~3 km) suggests (i) that the presence of an overdeepened trough may be a critical component influencing glacier behaviour and moraine formation; and (ii) that the volume of the Waiho Loop is significantly greater than previously thought. Using a one-dimensional flowline model, two rock-avalanche-based scenarios for the formation of Loop are tested: first, that a rock avalanche generated a significant advance of the glacier terminus from a location within the confined mountain valley to the Loop; and second, that the rock avalanche occurred while the glacier was retreating from its long-occupied terminus at the distal margin of its overdeepened trough close to the position of the Loop during the Last Glacial Interglacial Transition (LGIT) 13000-11000 yrs BP. Results from the first test demonstrate that a rock avalanche could not have generated a significant advance of the Franz Josef Glacier terminus from a location within the confined mountain valley to form the Loop, because most of the rock avalanche debris could not be advected to the terminus to form a sufficiently high moraine before the ice in the upper catchment becomes

    Phrenologists believed that specific brain regions corresponded to certain character traits. In addition, the size of each brain region was believed to determine the strength of the respective trait. Phrenology originated in Austria with Franz Josef Gall and was popularized and commercialized in America at the end of the 19th century by Orson Squire Fowler. In this project, we conducted a replication of Fowler’s phrenology in order to better understand the specificity of the manualized methodology, the extent to which the methodology allowed for positive versus negative analyses, and the implications for the scientific rejection and public acceptance of phrenology. The results of our replication revealed that the subjective judgments and biases of the examiner strongly influence the results of phrenological analyses.

    Based on extensive voluminous literary data, a comparison of the Harpacticoida faunas of the Black Sea; the Sea of Azov; and the Caspian, Baltic, Barents, White, Kara, Laptev, and East Siberian seas, as well as of the Spitsbergen and Franz Josef Land areas, was performed. The degree of community and specificity of the faunas of different regions was estimated and the general patterns of the latitudinal variability in the species compositions were revealed. It is shown that the Harpacticoida faunas of geographically separated areas and even those isolated from each other such as those of the Black Sea, the Sea of Azov, and the Caspian Sea are rather similar; an hypothesis is put forward that this is caused by the common history of the seas’ formation. In contrast, the faunas of the Arctic seas (Barents, White, Kara, Laptev, and East Siberian), whose water areas are closely connected, are considerably different, being related to their different temperature conditions.

    This paper reports that more than 10 years of oil and gas exploration in the Norwegian and Russian Barents Sea has resulted in few and moderate finds, mainly restricted to the Hammerfest basin. Major gas discoveries are reported off Russia. The Barents Sea off the two countries covers about 1.2 million sq km. Including the arctic Svalbard and Franz Josef archipelagoes, this area is comparable in size to the entire Gulf of Mexico or the U.S. east of the Mississippi River. Snohvit gas field is estimated by the Norwegian Petroleum Directorate to contain 76 billion cu m of gas plus a thin oil zone. Many wells have revealed that Barents Sea structures have earlier been filled to a greater extent but the oil has leaked out.

    Although the subject of ongoing incestuous abuse during adulthood has never been addressed in a systematic way in the professional literature, accounts of such cases have been appearing for many years. The Josef Fritzl case added a new impetus to reporting such abuses in the popular press. The current study presents 44 such cases from 24 countries that appeared in English-language press accounts over 5 years commencing January 2007. These cases are discussed in light of the minimal coverage of such issues in the professional literature. The results of this study suggest that cases of enduring incest are not rare and typically incorporate decades of sexual abuse, frequently result in pregnancies, and commonly incorporate ongoing violence and death threats.

    In order to improve the power calibration process and to benchmark the existing computational model of the TRIGA Mark II reactor at the Josef Stefan Inst. (JSI), a bilateral project was started as part of the agreement between the French Commissariat a l'energie atomique et aux energies alternatives (CEA) and the Ministry of higher education, science and technology of Slovenia. One of the objectives of the project was to analyze and improve the power calibration process of the JSI TRIGA reactor (procedural improvement and uncertainty reduction) by using absolutely calibrated CEA fission chambers (FCs). This is one of the few available power density distribution benchmarks for testing not only the fission rate distribution but also the absolute values of the fission rates. Our preliminary calculations indicate that the total experimental uncertainty of the measured reaction rate is sufficiently low that the experiments could be considered as benchmark experiments.

    Based on seismological monitoring data specifying earthquake epicenters, a new map is made for the Western sector of the Russian Arctic region. The seismicity data is reworked in detail by specifying the epicentral positions of earthquakes and adding data on weak seismicity for areas which were earlier insufficiently studied, including those at the boundary of the Arctic Shelf of the Russian Federation. The fundamental possibility of applying seismological observations to construct a regional geodynamic map is discussed (in particular, the important role of island-based seismic stations). The possibility of specifying the nature of seismicity in terms of spectral-temporal analysis (STAN) of waveforms based on data from the new seismic station on the Franz Josef Land is considered. Possible application of the character of seismicity obtained from geophysical data to specify the geodynamic nature of events accompanying interaction of the ridge and shelf spreading is discussed.

    2015-01-01

    The small size of nuclei of the budding yeast Saccharomyces cerevisiae limits the utility of light microscopy for analysis of the subnuclear distribution of chromatin-bound proteins. Surface spreading of yeast nuclei results in expansion of chromatin without loss of bound proteins. A method for surface spreading balances fixation of DNA bound proteins with detergent treatment. The method demonstrated is slightly modified from that described by Josef Loidl and Franz Klein. The method has been used to characterize the localization of many chromatin-bound proteins at various stages of the mitotic cell cycle, but is especially useful for the study of meiotic chromosome structures such as meiotic recombinosomes and the synaptonemal complex. We also describe a modification that does not require use of Lipsol, a proprietary detergent, which was called for in the original procedure, but no longer commercially available. An immunostaining protocol that is compatible with the chromosome spreading method is also described. PMID:26325523

    Russian-born, Vienna-trained neurologist and neuropathologist Ilya Mark Scheinker collaborated with Josef Gerstmann and Ernst Sträussler in 1936 to describe the familial prion disorder now known as Gerstmann-Sträussler-Scheinker disease. Because of Nazi persecution following the annexation of Austria by Nazi Germany, Scheinker fled from Vienna to Paris, then after the German invasion of France, to New York. With the help of neurologist Tracy Putnam, Scheinker ended up at the University of Cincinnati, although his position was never guaranteed. He more than doubled his prior publications in America, and authored three landmark neuropathology textbooks. Despite his publications, he was denied tenure and had difficulty professionally in the Midwest because of prejudice against his European mannerisms. He moved back to New York for personal reasons in 1952, dying prematurely just 2 years later. Scheinker was twice uprooted, but persevered and eventually found some success as a refugee.

  17. Continental Flood Basalts of Bennett Island, East Siberian Sea: High Arctic Geodynamics

    2014-05-01

    Volcanism provides a means of tracing mantle melting events and crustal evolution. The High Arctic includes a rich portfolio of volcanic rocks outcropping in the Circum-Arctic borderlands and imaged geophysically beneath the Alpha-Mendeleev Ridge that have been lumped together as a High-Arctic Large Igneous Province (HALIP). However, the ages (c. 440-60 Ma) and compositions (tholeiitic-alkaline-calc-alkaline) reported varies considerably and geological correlations remain elusive. One of the possible correlative events is the formation of continental flood basalts and sills in the Canadian Arctic Islands, Svalbard, Franz Josef Land and Bennett Island. These flood basalts have previously been linked to mantle plume melting and may represent a short-lived LIP event at c. 124-122 Ma. We present new data for a 350 m thick continental flood basalt succession at Bennett Island examined during fieldwork in Septemer 2013 on a joint Russian (VSEGEI) - Swedish (SWEDARCTIC) expedition to the De Long Archipelago. This volcanic succession is composed of 20 near-horisontal, undeformed flow units overlying a thin sedimentary succession of Cretaceous age (?) including coal seams and possibly volcaniclastic material that, in turn, unconformably overlies a more steeply dipping succession of Cambrian and Ordovician sediments. The flows are thinnest (c. 2-10 m) and aphyric to very-sparsely olivine-phyric in the lower portion. In contrast, the flows in the upper portion are thicker (>20 m) and aphyric to sparsely plagioclase-phyric. We will discuss new petrographic and compositional data for the Bennett Island flood basalts, possibly including new U-Pb age data. The aim is to evaluate their petrogenesis, to discuss their possible correlation to the flood basalt and sill successions of the Canadian Arctic Islands, Svalbard and Franz Josef Land and evaluate the geodynamic evolution of the High Arctic.

  18. Rapid formation of a sea ice barrier east of Svalbard

    Daily SeaWinds scatterometer images acquired by the QuikSCAT satellite show an elongated sea ice feature that formed very rapidly (˜1-2 days) in November 2001 east of Svalbard over the Barents Sea. This sea ice structure, called "the Svalbard sea ice barrier," spanning approximately 10° in longitude and 2° in latitude, restricts the sea route and poses a significant navigation hazard. The secret of its formation appears to lie in the bottom of the sea: A comparison between bathymetry from the International Bathymetric Chart of the Arctic Ocean data and the pattern of sea ice formation from scatterometer data reveals that the sea ice barrier conforms well with and stretches above a deep elongated channel connecting the Franz Josef-Victoria Trough to the Hinlopen Basin between Svalbard and Franz Josef Land. Historic hydrographic data from this area indicate that this sea channel contains cold Arctic water less than 50 m below the surface. Strong and persistent cold northerly winds force strong heat loss from this shallow surface layer, leading to the rapid formation of the sea ice barrier. Heat transfer rates estimated from European Centre for Medium-Range Weather Forecasts temperature and wind data over this region suggest that the surface water along the deep channel can be rapidly cooled to the freezing point. Scatterometer results in 1999-2003 show that sea ice forms in this area between October and December. Understanding the ice formation mechanisms helps to select appropriate locations for deployment of buoys measuring wind and air-sea temperature profile and to facilitate ice monitoring, modeling, and forecasting.

    The article is based on the results of helminthological observations made on kittiwake Rissa tridactyla and glaucous gull Larus hyperboreus in 1991-2001 in different areas of the Barents Sea (Eastern Murman coast, Franz Josef Land, Novaya Zemlya, Spitzbergen). 18 helminth species (2 trematodes, 11 cestodes, 4 nematodes, and 2 acanthocephalans) were recorded in the kittiwakes and 19 (3 trematodes, 9 cestodes, 5 nematodes and 2 acanthocephalans) species were recorded in the glaucous gulls. Trematodes were absent in the birds collected at the Franz Josef Land and the northern island of Novaya Zemlya. 3 trematode species, namely Gymnophallus sp. (somateria?), Microphallus sp. 1 (M. pseudopygmaeus), and Cryptocotyle lingua were found in the glaucous gulls of western Spitzbergen. It was supposed that the life cycles of these parasites can be completed there. On the other hand, coastal ecosystems of Arctic archipelagoes turn out to be favourable for the transmission of some cestodes. This is closely connected with the regional traits in the marine bird diet, namely the increase of the amphipod (intermediate hosts of hymenolepidids and some dilepidids) and polar cod (supposed second intermediate host for some tetrabothriids) portion in Arctic. As a result, cestodes are the base of the helminth fauna of kittiwakes and glaucous gulls of the Barents Sea, by their species richness, prevalence and abundance. Nematodes and acanthocephalans were represented by a few species with low infection intensity. The main ecological factors affected the regional difference in the species richness and abundance of the helminths parasitising kittiwakes and glaucous gulls in the Barents Sea are proposed. Those are regional climatic features and regional traits in the behaviour and food priorities of birds, and also the distribution of the helminths intermediate hosts, invertebrates and fishes. The phenomenon of host specificity lowering with respect to the definitive host was recorded in some

    Rheumatoid arthritis (RA) is a systemic autoimmune and inflammatory disease that mainly alters the synovial joints and ultimately leads to their destruction. The involvement of the immune system and its related cells is a basic trademark of autoimmune-associated diseases. The present work focuses on network analysis and its functional characterization to predict novel targets for RA. The interactive model called as rheumatoid arthritis drug-target-protein (RA-DTP) is built of 1727 nodes and 7954 edges followed the power-law distribution. RA-DTP comprised of 20 islands, 55 modules and 123 submodules. Good interactome coverage of target-protein was detected in island 2 (Q-Score 0.875) which includes 673 molecules with 20 modules and 68 submodules. The biological landscape of these modules was examined based on the participation molecules in specific cellular localization, molecular function and biological pathway with favourable p value. Functional characterization and pathway analysis through KEGG, Biocarta and Reactome also showed their involvement in relation to the immune system and inflammatory processes and biological processes such as cell signalling and communication, glucosamine metabolic process, renin-angiotensin system, BCR signals, galactose metabolism, MAPK signalling, complement and coagulation system and NGF signalling pathways. Traffic values and centrality parameters were applied as the selection criteria for identifying potential targets from the important hubs which resulted into FOS, KNG1, PTGDS, HSP90AA1, REN, POMC, FCER1G, IL6, ICAM1, SGK1, NOS3 and PLA2G4A. This approach provides an insight into experimental validation of these associations of potential targets for clinical value to find their effect on animal studies. PMID:26286007

    Background The renin-angiotensin-aldosterone-system (RAAS) is critical for regulation of blood pressure and fluid balance and influences cardiovascular remodeling. Dysregulation of the RAAS contributes to cardiovascular and renal morbidity. The genetic architecture of circulating RAAS components is incompletely understood. Methods and Results We meta-analyzed genome-wide association data for plasma renin activity (n=5,275), plasma renin concentrations (n=8,014) and circulating aldosterone (n=13,289) from up to four population-based cohorts of European and European-American ancestry, and assessed replication of the top results in an independent sample (n=6,487). Single nucleotide polymorphisms (SNPs) in two independent loci displayed associations with plasma renin activity atgenome-wide significance (p<5×10-8). A third locus was close to this threshold (rs4253311 in kallikrein B [KLKB1], p=5.5×10-8). Two of these loci replicated in an independent sample for both plasma renin and aldosterone concentrations (SNP rs5030062 in kininogen 1 [KNG1]: p=0.001 for plasma renin, p=0.024 for plasma aldosterone concentration; rs4253311 with p<0.001 for both plasma renin and aldosterone concentration). SNPs in the NEBL gene reached genome-wide significance for plasma renin concentration in the discovery sample (top SNP rs3915911, p= 8.81×10-9), but did not replicate (p=0.81). No locus reached genome-wide significance for aldosterone. SNPs rs5030062 and rs4253311 were not related to blood pressure or renal traits; in a companion study, variants in the kallikrein B locus were associated with B-type natriuretic peptide concentrations in African-Americans. Conclusions We identified two genetic loci (kininogen 1 and kallikrein B) influencing key components of the RAAS, consistent with the close interrelation between the kallikrein-kinin system and the RAAS.

    A gene from Actinomyces sp. Korean native goat (KNG) 40 that encodes an endo-β-1,4-glucanase, EG1, was cloned and expressed in Escherichia coli (E. coli) DH5α. Recombinant plasmid DNA from a positive clone with a 3.2 kb insert hydrolyzing carboxyl methyl-cellulose (CMC) was designated as pDS3. The entire nucleotide sequence was determined, and an open-reading frame (ORF) was deduced. The ORF encodes a polypeptide of 684 amino acids. The recombinant EG1 produced in E. coli DH5α harboring pDS3 was purified in one step using affinity chromatography on crystalline cellulose and characterized. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis/zymogram analysis of the purified enzyme revealed two protein bands of 57.1 and 54.1 kDa. The amino terminal sequences of these two bands matched those of the deduced ones, starting from residue 166 and 208, respectively. Putative signal sequences, a Shine–Dalgarno-type ribosomal binding site, and promoter sequences related to the consensus sequences were deduced. EG1 has a typical tripartite structure of cellulase, a catalytic domain, a serine-rich linker region, and a cellulose-binding domain. The optimal temperature for the activity of the purified enzyme was 55°C, but it retained over 90% of maximum activity in a broad temperature range (40°C to 60°C). The optimal pH for the enzyme activity was 6.0. Kinetic parameters, Km and Vmax of rEG1 were 0.39% CMC and 143 U/mg, respectively. PMID:26732336

    Background GIC is the most commonly used restorative material in pediatric dentistry since it has got various advantages like fluoride release, anticariogenic property and chemical adhesion to tooth but a major disadvantage is its contraindication in posterior teeth because of poor mechanical properties. Aim The purpose of this study is a modest attempt to explore the influence of the addition of 8% hydroxyapatite to conventional GIC on its compressive strength when immersed in different storage media and antibacterial activity. Materials and Methods One hundred and twenty six pellets of the specific dimension of 6 x 4 mm were prepared and divided into 6 groups and were immersed in deionized water, artificial saliva, lactic acid solution respectively for three hours everyday over 30 days test period. The compressive strength was measured by using a universal testing machine (AG-50kNG) at cross head of 1mm2/min and strength was determined after 1 day, 7 days, 30 days respectively and the antibacterial activity evaluated against Streptococcus mutans strain in brain heart infusion broth using serial dilution method. Statistical Analysis Group wise comparisons were made by one-way ANOVA followed by post-hoc Tukey’s test, Intergroup comparison was done with Mann-Whitney test. Results GIC±HAp showed significantly greater antibacterial activity against Streptococcus mutans when compared to GIC group. There was no statistically significant change in the compressive strength among the groups except for group 3 and group 6 when immersed in lactic acid had shown significant difference at the end of 24 hours. Conclusion The addition of 8% hydroxyapatite to GIC showed marked increased in the antibacterial activity of the conventional GIC against caries initiating organism without much increase in the compressive strength of the GIC when immersed in the different storage media.

    Aim: The novel anticancer compound TM208 is an EGFR tyrosine kinase inhibitor (EGFR-TKI). Since the development of resistance to EGFR-TKIs is a major challenge in their clinical usage, we investigated the profiles of resistance following continuous treatment with TM208 in human breast cancer xenograft mice, and identified the relationship between the tumor pEGFR levels and tumor growth inhibition. Methods: Female BALB/c nude mice were implanted with human breast cancer MCF-7 cells, and the xenograft mice received TM208 (50 or 150 mg·kg−1·d−1, ig) or vehicle for 18 d. The pharmacokinetics (PK) and pharmacodynamics (PD) of TM208 were evaluated. Results: The PK properties of TM208 were described by a one-compartment model with first-order absorption kinetics. Our study showed the inhibitory effects of TM208 on tumor pEGFR levels gradually reached a maximum effect, after which it became weaker over time, which was characterized by a combined tolerance/indirect response PD model with an estimated EC50 (55.9 μg/L), as well as three parameters ('a' of 27.2%, 'b' of 2730%, 'c' of 0.58 h−1) denoting the maximum, extent and rate of resistance, respectively. The relationship between the tumor pEGFR levels and tumor growth inhibition was characterized by a combined logistic tumor growth/transit compartment model with estimated parameters associated with tumor growth characteristics kng (0.282 day−1), drug potency kTM208 (0.0499 cm3/day) and the kinetics of tumor cell death k1 (0.141 day−1), which provided insight into drug mechanisms and behaviors. Conclusion: The proposed PK/PD model provides a better understanding of the pharmacological properties of TM208 in the treatment of breast cancer. Furthermore, simulation based on a tolerance model allows prediction of the occurrence of resistance. PMID:27133303

    Seed dormancy has fundamental importance in plant survival and crop production; however, the mechanisms regulating dormancy remain unclear [1-3]. Seed dormancy levels generally decrease during domestication to ensure that crops successfully germinate in the field. However, reduction of seed dormancy can cause devastating losses in cereals like wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) due to pre-harvest sprouting, the germination of mature seed (grain) on the mother plant when rain occurs before harvest. Understanding the mechanisms of dormancy can facilitate breeding of crop varieties with the appropriate levels of seed dormancy [4-8]. Barley is a model crop [9, 10] and has two major seed dormancy quantitative trait loci (QTLs), SD1 and SD2, on chromosome 5H [11-19]. We detected a QTL designated Qsd2-AK at SD2 as the single major determinant explaining the difference in seed dormancy between the dormant cultivar "Azumamugi" (Az) and the non-dormant cultivar "Kanto Nakate Gold" (KNG). Using map-based cloning, we identified the causal gene for Qsd2-AK as Mitogen-activated Protein Kinase Kinase 3 (MKK3). The dormant Az allele of MKK3 is recessive; the N260T substitution in this allele decreases MKK3 kinase activity and appears to be causal for Qsd2-AK. The N260T substitution occurred in the immediate ancestor allele of the dormant allele, and the established dormant allele became prevalent in barley cultivars grown in East Asia, where the rainy season and harvest season often overlap. Our findings show fine-tuning of seed dormancy during domestication and provide key information for improving pre-harvest sprouting tolerance in barley and wheat. PMID:26948880

    Predicting and controlling the concentrations of redox-sensitive elements are primary concerns for environmental remediation of contaminated sites. These predictions are complicated by dynamic flow processes as hydrologic variability is a governing control on conservative and reactive chemical concentrations. Subsurface heterogeneity in the form of layers and lenses further complicates the flow dynamics of the system impacting chemical concentrations including redox-sensitive elements. In response to these complexities, this study investigates the role of heterogeneity and hydrologic processes in an effective parameter upscaling scheme from the column to the landfill scale. We used a Markov chain Monte Carlo (MCMC) algorithm to derive upscaling coefficients for hydrological and geochemical parameters, which were tested for variations across heterogeneous systems (layers and lenses) and interaction of flow processes based on the output uncertainty of dominant biogeochemical concentrations at the Norman Landfill site, a closed municipal landfill with prevalent organic and trace metal contamination. The results from MCMC analysis indicated that geochemical upscaling coefficients based on effective concentration ratios incorporating local heterogeneity across layered and lensed systems produced better estimates of redox-sensitive biogeochemistry at the field scale. MCMC analysis also suggested that inclusion of hydrological parameters in the upscaling scheme reduced the output uncertainty of effective mean geochemical concentrations by orders of magnitude at the Norman Landfill site. This was further confirmed by posterior density plots of the scaling coefficients that revealed unimodal characteristics when only geochemical processes were involved, but produced multimodal distributions when hydrological parameters were included. The multimodality again suggests the effect of heterogeneity and lithologic variability on the distribution of redox-sensitive elements at the

    Recently Van-Brunt and Visser (2015 J. Phys. A: Math. Theor. 48 225207) succeeded in explicitly evaluating the Baker–Campbell–Hausdorff (BCH) expansion series for the noncommuting operators X and Y, provided that the two operators satisfy the commutation relation: [X,Y]={uX}+{vY}+{cI}, and the operator I commutes with both of them. In this comment we show that the closed-form BCH formula of this special case can be straightforwardly derived by the means of the Wei–Norman theorem and no summation of the infinite series is needed.

    Calculations are presented of the specific energy absorption rate, SAR, in the lower arm of the NRPB anatomically realistic voxel model. NORMAN, for induced currents from 100 kHz to 80 MHz. The wrist region has a narrow cross section and contains little high conductivity muscle, comprising mainly low conductivity bone, tendon and fat. Consequently there is a channelling of the current through the high conductivity muscle, which produces high, localised values of the SAR. Values averaged over 10 g and 100 g of tissue are calculated as a function of the current flowing through the wrist. PMID:11572647

    To decontaminate dredged harbor sediments by bioremediation or electromigration processes, adding biosurfactants could enhance the bioavailability or mobility of contaminants in an aqueous phase. Pure amphisin from Pseudomonas fluorescens DSS73 displays increased effectiveness in releasing polycyclic aromatic hydrocarbons (PAHs) strongly adsorbed to sediments when compared to a synthetic anionic surfactant. Amphisin production by the bacteria in the natural environment was also considered. DSS73's growth is weakened by three model PAHs above saturation, but amphisin is still produced. Estuarine water feeding the dredged material disposal site of a Norman harbor (France) allows both P. fluorescens DSS73 growth and amphisin production. PMID:21673923

    Techniques for the determination of leaf area index or leaf angle distribution from remote-sensing canopy-reflectance (CR) measurements are developed on the basis of empirical models relating CR to parameters such as soil and vegetation spectral properties, solar flux, and viewing angle. A general procedure for inverting CR models is presented and applied to the models of Suits (1972), Verhoef and Bunnik (1981), and Norman (1979) in the IR range. Numerical results for a soybean canopy are compared in a table, and the error sensitivity of the inverted models is shown to be relatively high, requiring the use of ancillary data such as soil reflectance, leaf reflectance, and leaf transmittance.

Also rejecting the libertarian hypothesis that there is no right to a decent minimum of care, he contends that the claim that society should guarantee certain health care services can be supported by a pluralistic approach encompassing special right-claims, harm prevention, prudential arguments emphasizing public health benefits, and beneficence.

    Woodhenge and the Trinity chapel, Canterbury, are strikingly similar in outline. One is megalithic, the other Norman Christian over Saxon Christian. An analysis of the geometry shows that both are based on Pythagorean triangles: Woodhenge with sides, 6, 17.5, and 18.5, and Canterbury with sides 12, 72, and 73 in megalithic yards. The structurally more recent eastern end of Canterbury Cathedral may have been built over and around an older megalithic site. The longitudinal axes of the composite cathedral differ by 2 degrees , and these, if aligned on Betelgeuse, would indicate buried megalithic structures dating from 2300, 1900, and 1500 B.C.

First, we present a case study in which the two programs are used to examine the differences between the stages along the way from lattice theory to Boolean algebra. Second, we answer several questions posed by Norman Megill and Mladen Pavicic on ortholattices and orthomodular lattices. The questions from Megill and Pavicic arose in their study of quantum logics, which are being investigated in connection with proposed computing devices based on quantum mechanics. Previous questions of a similar nature were answered by McCune and MACE in [2].

Modulation in the [110] direction with a periodicity of 4d_110 has been observed in some of these samples [1,2]. For each of these samples we have investigated the bandgap as a function of temperature (4K < T < 300K) using Fourier transform infrared spectroscopy techniques. Our preliminary results suggest that the observed bandgaps are less than that predicted by published empirical relationships for the random alloys. We interpret the observed bandgap reduction (of the order of 5%) to be due to the CuPt ordering from which the order parameter can be extracted.

    Research was conducted to develop a method for obtaining floating pan evaporation rates in a small (less than 10,000 m2) wetland, lagoon, or pond. Floating pan and land pan evaporation data were collected from March 1 to August 31, 2005, at a small natural wetland located in the alluvium of the Canadian River near Norman, Oklahoma, at the U.S. Geological Survey Norman Landfill Toxic Substances Hydrology Research Site. Floating pan evaporation rates were compared with evaporation rates from a nearby standard Class A evaporation pan on land. Floating pan evaporation rates were significantly less than land pan evaporation rates for the entire period and on a monthly basis. Results indicated that the use of a floating evaporation pan in a small free-water surface better simulates actual physical conditions on the water surface that control evaporation. Floating pan to land pan ratios were 0.82 for March, 0.87 for April, 0.85 for May, 0.85 for June, 0.79 for July, and 0.69 for August. ?? 2008 American Water Resources Association.

    Rates of in situ microbial sulfate reduction in response to geochemical perturbations were determined using Native Organism Geochemical Experimentation Enclosures (NOGEEs), a new in situ technique developed to facilitate evaluation of controls on microbial reaction rates. NOGEEs function by first trapping a native microbial community in situ and then subjecting it to geochemical perturbations through the introduction of various test solutions. On three occasions, NOGEEs were used at the Norman Landfill research site in Norman, Oklahoma, to evaluate sulfate-reduction rates in wetland sediments impacted by landfill leachate. The initial experiment, in May 2007, consisted of five introductions of a sulfate test solution over 11 d. Each test stimulated sulfate reduction with rates increasing until an apparent maximum was achieved. Two subsequent experiments, conducted in October 2007 and February 2008, evaluated the effects of concentration on sulfate-reduction rates. Results from these experiments showed that faster sulfate-reduction rates were associated with increased sulfate concentrations. Understanding variability in sulfate-reduction rates in response to perturbations may be an important factor in predicting rates of natural attenuation and bioremediation of contaminants in systems not at biogeochemical equilibrium.

  18. The list strength effect: a contextual competition account.

    PubMed

    Diana, Rachel A; Reder, Lynne M

    2005-10-01

    Research on the list strength effect (LSE) has shown that learning some words on a list more strongly than others impairs memory for the weakly learned words when tested with a recall task. Norman (2002) demonstrated that the LSE also occurs within the recollection process of a recognition test. In this study, a mechanistic dual-process account of the LSE was tested that simultaneously makes predictions concerning additional sources of context in interference effects. In two experiments, we attempted to replicate Norman's (2002) findings and provide the basis for our modeling efforts. We found evidence for a recollection LSE in raw measures of responding, with memory performance also benefiting from reinstatement of perceptual characteristics at test. However, large differences in the hits between the lists were accompanied by small differences in false alarms, such that when d' is calculated, differences between the lists are not significant. We propose an account of the LSE whereby the actual effect of competition between items on the list is small, although present, and difficult to distinguish from large effects of bias due to the strength manipulations. We argue that our findings provide support for a mechanistic explanation of LSE that is based on competition of source activation and changes in the thresholds for responses. PMID:16532860

  19. The response of tropical Australian estuaries to a sea level rise

    Wolanski, E.; Chappell, J.

    1996-02-01

    Estuaries in tropical Australia have a low sediment yield (about 5-20 tonnes km -2 yr -1). The estuaries formed when rising post-glacial sea level invaded coastal valleys 7 to 9000 years ago. Geomorphological and stratigraphic data show that mangrove swamps developed on the flooded plains and in some cases their substrate kept pace with the rising sea level. The bulk of the sediment originated from the sea. When sea level stabilised, 6000 years ago, the flood plains prograded seaward. The channels now are generally stable and in some cases are inherited from the progradation phase. The response of these estuaries to a sea level rise may be inferred both from their evolution during post glacial sea level rise and from hydrodynamics-sedimentological models calibrated against measurements of tidal processes. This was undertaken for Coral Creek, the South Alligator River and the Norman River in north Australia. Modelling indicates that a future sea level rise will generate changes in the dynamics and channel dimensions which mimic post glacial changes. In the macrotidal South Alligator the floodplain will revert to mangrove, the mouth region will widen and sediment will move upstream and onto the floodplain. In the mesotidal, diurnal Norman the channel will widen throughout and sediment will be transported seawards. In Coral Creek the mangrove will retreat landwards.

  20. Spatio-temporal evolution of biogeochemical processes at a landfill site

    Predictions of fate and transport of contaminants are strongly dependent on spatio-temporal variability of soil hydraulic and geochemical properties. This study focuses on time-series signatures of hydrological and geochemical properties at different locations within the Norman landfill site. Norman Landfill is a closed municipal landfill site with prevalent organic contamination. Monthly data at the site include specific conductance, δ18O, δ2H, dissolved organic carbon (DOC) and anions (chloride, sulfate, nitrate) from 1998-2006. Column scale data on chemical concentrations, redox gradients, and flow parameters are also available on daily and hydrological event (infiltration, drainage, etc.) scales. Since high-resolution datasets of contaminant concentrations are usually unavailable, Wavelet and Fourier analyses were used to infer the dominance of different biogeochemical processes at different spatio-temporal scales and to extract linkages between transport and reaction processes. Results indicate that time variability controls the progression of reactions affecting biodegradation of contaminants. Wavelet analysis suggests that iron-sulfide reduction reactions had high seasonal variability at the site, while fermentation processes dominated at the annual time scale. Findings also suggest the dominance of small spatial features such as layered interfaces and clay lenses in driving biogeochemical reactions at both column and landfill scales. A conceptual model that caters to increased understanding and remediating structurally heterogeneous variably-saturated media is developed from the study.

    A new species of Merizocotyle Cerfontaine, 1894 (Monogenea: Monocotylidae) is described from the nasal tissues of three deep sea rajid skates: the southern thorny skate, Amblyraja doellojuradoi (Pozzi), broadnose skate, Bathyraja brachyurops (Fowler), and yellownose skate, Zearaja chilensis (Guichenot), collected off Buenos Aires Province, Argentina, southwest Atlantic Ocean. Two additional species of sympatric rajid, the white-dotted skate, Bathyraja albomaculata (Norman), and the Patagonian skate, Bathyraja macloviana (Norman), were also examined but no merizocotylines were found. The taxonomy of the Merizocotylinae is not widely accepted and, as a result, the status of Thaumatocotyle and Mycteronastes, and their proposed synonymy with Merizocotyle are currently under discussion. The new species differs from its congeners by having a unique haptoral structure, 6 peripheral loculi that are asymmetrically arranged (one much smaller, indistinctly located in the left or right side of the haptor). The presence of the new species in three sympatric species of Rajidae belonging to distinct genera and subfamilies, as well as its absence in sympatric congenerics indicates the lack of phylogenetic host specificity. Host ecology and geographical distribution appear to be more important than host phylogeny in determining the distribution of this parasite across potential hosts in the region. This constitutes the first record of Merizocotyle in the southwestern Atlantic Ocean. PMID:25065126

    The present paper reviews the material of three species of Asterocheres Boeck 1859 deposited in four different Zoological European museums as part of the ongoing taxonomical revision of this genus. Asterocheres sarsi Bandera & Conradi 2009, the species described by Sars in 1915 as Ascomyzon latum (Brady 1880) and lately recognized as a distinct species by Bandera and Conradi in 2009 is fully described in this paper from material collected by Sars in Norway in 1915 and deposited in The Natural History Museum of the University of Oslo. Asterocheres complexus Stock, 1960 which has been sometimes confused with A. sarsi is redescribed from material collected by Stock in France in 1959 and deposited in the Zoological Museum of the University of Amsterdam. Furthermore, a new species, previously misidentified as A. suberitis Gieisbrecht 1897, from the Norman`s collection of The Natural History Museum of London, is described as A. eugenioi, new species. These three species, A. complexus, A. eugenioi, and A. sarsi share the general appearance of body thanks to the pointed posterolateral angle of the epimeral area of somite bearing leg 3, sometimes slightly produced into backwardly directed processes, and somite bearing leg 4 largely concealed under somite bearing leg 3.

    Calculations of specific energy absorption rate (SAR) have been performed on the rescaled NORMAN 7-y-old voxel model and the Electronics and Telecommunications Research Institute (ETRI) child 7-y-old voxel model in the standing arms down, arms up and sitting postures. These calculations were for plane-wave exposure under isolated and grounded conditions between 10 MHz and 3 GHz. It was found that there was little difference at each resonant frequency between the whole-body averaged SAR values calculated for the NORMAN and ETRI 7-y-old models for each of the postures studied. However, when compared with the arms down posture, raising the arms increased the SAR by up to 25%. Electric field values required to produce the International Commission on Non-Ionizing Radiation Protection and Institute of Electrical and Electronic Engineers public basic restriction were calculated, and compared with reference levels for the different child models and postures. These showed that, under certain worst-case exposure conditions, the reference levels may not be conservative. PMID:19589878

    The Barents Sea is one of the key regions for understanding of the postglacial history of the climate and circulation of the World Ocean. There are the limits of warm North Atlantic waters penetration to the Arctic and a zone of interaction between Atlantic and Arctic waters. The Barents Se's limits are the deep Norwegian Sea in the West, the Spitsbergen Island and the Franz Josef Land and the deep Nansen trough in the North, the Novaya Zemlya archipelago in the East and the North shore of Europe in the South. An analysis of Eurasian-Arctic continental margin shows correspondence between the rift systems of the shelf with those of the ocean. This relation can be observed in the central Arctic region. All the rift systems underlying the sediment basin are expressed in the sea bed relief as spacious and extensive graben valleys burnished by lobes. Two transverse trenches cross both shelf and continental slope, namely the Medvezhinsky trench between Norway and Spitsbergen in the West and the Franz Victoria trench between Spitsbergen and the Franz Josef Land in the North. The Barents and the Kara Seas are connected by the Kara Gate Strait and wide transverse trough of Saint Anna in the North-West. The recent assessment of the eolian solid sediment supply to the Barents Sea is about 0.904 tons. The Barents Sea as a whole should be considered as "starving" in terms of its feeding with solid sediment matter. Observations show the considerable part of the sea bottom to be free of Holocene sediment cover. The more ancient Quaternary units or bedrock can be seen at the bottom surface. This phenomenon is the most typical for arches of relatively shallow elevations. Thick accumulations of new sediments are connected with fjords. The amount of sea ice delivered from the Barents Sea to the Arctic Ocean is 35 km3 a year. This value should be added by iceberg delivery from the North island of Novaya Zemlya, the Franz Josef Land, the Spitsbergen Island and North Norway but most of

    Eruption of the Siberian Traps at the Permo-Triassic boundary [~250 Ma] produced more than 3 x 106 km3 of rapidly emplaced magma throughout a region ~2.5 x 106 km2 in extent. Dates from the New Siberian Islands of 252 ± 2 Ma (Kuzmichev & Pease, 2007) indicate that Siberian Trap-related magmas are found ~500 km to the east of where they are generally shown to terminate to the west of the Lena River. Cenozoic opening of the Eurasian Basin would account for some of this discrepancy. A Siberian Trap mantle plume in an absolute reference frame fixed to the present day location of the Iceland hot spot, tracks through time across the Taimyr Peninsula region during the Late Triassic period and then to north of the Severnaya Zemlya archipelago by the end of the Middle Jurassic. With the exception of some Middle Triassic dates from the Taimyr Peninsula there is no apparent expression of a hot spot track during the this period. Motion of Laurasia in a paleomagnetically controlled reference frame has the Franz Josef Land archipelago over the fixed hotspot from about 155 Ma to 147 Ma prior to the early phase of the High Arctic Large Igneous Province [HALIP], generally taken to be 130 Ma to 120 Ma. Campsie et al (1988) have one date of 145 Ma from samples collected by Fridthof Nansen in 1895-1896 on Solsberi Island. Dibner et al (1988) have a dozen ages from dolerite samples from various islands spanning the period 175 ±12 Ma to 138 ±10 Ma with five of them between 158 Ma to 144 Ma. During the Late Jurassic into the earliest Cretaceous the track of the fixed hotspot follows the future margin of the Barents Shelf just inboard of a reconstructed Lomonosov Ridge. By the end of the Valanginian, the hotspot tracks curves slightly, mimicking the southern curve of the Lomonosov Ridge off North America. The early phase of the HALIP moves the region of the northern Ellesmere Island over the hotspot while forming the Mendeleev and Alpha ridges. By middle Albian time, the Siberian Traps

    Extraordinary occasions for art of any kind - music, creative graphic and plastic arts, literature (classic, modern incl. science fiction), theatre, cinema, etc. - exist to harmonise individual personal interests with those of the humanity well-being and of the Nature and also to cultivate individual spirituality and the appropriate values. Arts can be applied as irreplaceable means for making any human being better, for improving his sense for solidarity and for increasing his ethical sensibility. An interest for the art should be cultivated already since the childhood. - How much of inspiration for numerous composers all over the world has been given by the Nature, how much of inspiration for people who by listening to such a music are increasing nobility of their behaviour as well as their friendly approach to the Nature. - Many classical music works have been written with a strong inspiration by the Nature itself from the past until today. The actual Year of the Czech Music gives the possibility to present the most famous Czech composers inspired by the Nature (selected examples only): Bedřich Smetana (1824 - 1884): At the sea shore - a concert etude for piano inspired by his stay in Göteborg (Sweden); Vltava (Moldau) - a symphonic poem from the cycle "My country" inspired by the river crossing Bohemia from the South to Prague; From the Bohemian woods and meadows - another symphonic poem from the same cycle. Antonín Dvořák (1841 - 1904): V přírodě (In the Nature) - a work for orchestra Leoš Janáček (1854 - 1928): Příhody li\\vsky Bystrou\\vsky (The Cunning Little Vixen) - an opera situated mostly in a forest.

  8. Constraints on the glacial erosion rule

    NASA Astrophysics Data System (ADS)

    Herman, Frédéric

    2016-04-01

    It is thought that glaciers erode their underlying bedrock mainly through abrasion and quarrying. Theories predict erosion to be proportional to ice-sliding velocity raised to some power: ˙e = Kguls (1) where ė is the erosion rate, and Kg a proportionality constant and l an exponent. By implementing such a rule in numerical models, it has been possible to reproduce typical glacial landscape features, such as U-shape valleys, hanging valleys, glacial cirques or fjords. Although there have been great advances in the level of sophistication of these models, for example through the inclusion of high-order ice dynamics and subglacial hydrology, the proportionality constant, and the exponent have remained poorly constrained parameters. Recently, two independent studies in the Antarctic Peninsula and Patagonian Andes (Koppes et al., 2015) and the Franz Josef Glacier, New Zealand (Herman et al., 2015) simultaneously collected erosion rate and ice velocity data to find that erosion depends non-linearly on sliding velocity, and that the exponent on velocity is about 2. Such a nonlinear rule is appealing because it may, in part, explain the observed variations in erosion rates globally. Furthermore, an exponent about 2 closely matches theoretical predictions for abrasion. Although it is tempting to argue that abrasion is the dominant process for fast flowing glaciers like the Franz Josef Glacier, there is a clear need for more data and better quantification for the role of quarrying. Both studies also led to very similar values for the proportionality constant Kg. These new results therefore imply that glacial erosion processes might be better constrained than previously thought. Given that glacial velocity can nowadays be measured and modeled at an unprecedented resolution, it may potentially become possible to use glacial erosion models in a predictive manner.

  9. Glacier surface melt characterization and trend analysis (1992-2011) in the Russian High Arctic from combined resolution-enhanced scatterometer and passive microwave data

    Global warming has been pronounced in the remote glacierized archipelagoes (Severnaya Zemlya, Novaya Zemlya and Franz Josef Land) of the Russian High Arctic (RHA) and its effect on the low altitude, high latitude small ice caps needs examination. The timing and spatial variability of snow melt onset, duration and intensity are key factors influencing mass balance and the ice marginal hydrological system as well as important indicators of glacial response to anthropogenic and natural forcings. Characterization and trend analysis of RHA glacier melt behaviors provide insight about assessing the mass loss rate under recent Arctic climate change. However, due to the harsh environment, long term records of glaciological data for RHA are limited, necessitating the application of remotely sensed data to accomplish the research. The high sensitivity to liquid water and the ability to penetrate non-precipitating clouds enables microwave remote sensing to detect glacier surface melt. The appearance of melt water in snow dramatically decreases the returned scatterometer radar signal from active microwave sensors and sharply augments passive microwave emission. Based on this feature, we combined resolution-enhanced ERS-1/2 C-band (1992-2000), QuickSCAT Ku-band (2000-2009), ASCAT C-band (2009-2011) scatterometer data and SSMI 37 GHz (1995-2007) vertically polarized passive microwave products from Brigham Young University and analyzed glacier surface melt trends from 1992 to 2011 with a spatial resolution downscaled to 4.45km. We concatenated scatterometer derived melt behaviors by overlapping years and refined the results based on passive microwave data. Cross-validation shows that melt timing to be consistent between the active and passive sensors. Trend analysis (α < 0.005) reveals that the average glacier surface melt onset date occurs earlier by approximately 0.85 days/year in Severnaya Zemlya which outpaced the mean advancing rate in the pan-Arctic.

    Northeast British Columbia, specifically the Horn River Basin (HRB) and Montney Trend, are among the largest shale gas production regions in western Canada. In contrast, there has been no large-scale hydraulic fracturing (HF) operation in the Northwest Territories in the Norman Wells region of the central Mackenzie valley. In this study, we investigate the effect of injection pressure, operation duration and injected volume on the observed seismicity in the HRB and Norman Wells regions and compare our observations with the pre-HF records. In the HRB, we apply the single-station location and waveform correlation methods to establish a homogenous earthquake catalog (2006/12-2011/12). In the Northwest Territories, we combine data from a local seismograph network of 4 stations plus a dense array of 7 stations located from 1 km to 50 km from the operation wells to locate earthquakes (2013/09-2014/07). In the HRB, the initial effect of an increased injected volume is an increase in earthquake frequency but not magnitude. Local earthquakes gradually become larger in magnitude as the scale of HF in the region expands. While the injection pressure during HF operations has been regulated at a relatively constant level, the massive increase of injection volume in 2010 and 2011 coincides with a series of ML>3 events. Relatively large seismic moment release (>1014 N m) occurred only when the monthly injected volume exceeded ~150,000 m3. In addition, we observe variable time lags, from days to up to 4 months between intense HF and the occurrence of a significant local earthquake. On the other hand, in the Norman Wells region, two small-scale HF were performed in 2014 with a total injected volume of ~ 14000 m3. We observed an increase in the number of micro-earthquakes (M < 2.0) during the HF period without a clear change in the overall seismic pattern. From these two observations, we conclude that HF operations do not necessarily result in an increase in the occurrence rate of

    Fundamental research related to organic geochemistry, fluid-rock interactions, and the processes by which fluids migrate through basins has long been a part of the U.S. Department of Energy Geosciences program. Objectives of this program were to emphasize those principles and processes which would be applicable to a wide range of problems associated with petroleum discovery, occurrence and extraction, waste disposal of all kinds, and environmental management. To gain a better understanding of the progress being made in understanding basinal fluids, their geochemistry and movement, and related research, and to enhance communication and interaction between principal investigators and DOE and other Federal program managers interested in this topic, this workshop was organized by the School of Geology and Geophysics and held in Norman, Oklahoma in November, 1991.

    Two recent item factor analyses of the Minnesota Multiphasic Personality Inventory (MMPI) classified the resulting factors according to a conceptual scheme offered by Norman's (1963) five factor model. The present article empirically evaluates those classifications by correlating MMPI factor scales with self-report and peer rating measures of the five factor model in a sample of 153 adult men and women. Both sets of predictions were generally supported, although MMPI factors derived in a normal sample showed closer correspondences with the five normal personality dimensions. MMPI factor scales were also correlated with 18 scales measuring specific traits within the broader domains of Neuroticism, Extraversion, and Openness. The nine Costa, Zonderman, McCrae, and Williams (1985) MMPI factor scales appear to give useful global assessments of four of the five factors; other instruments are needed to provide detailed information on more specific aspects of normal personality. The use of the five factor model in routine clinical assessment is discussed. PMID:3820053

    Regarding Norman Willcox's letter about the problems of using solar panels for domestic heating (August p21), I also have thermal solar panels installed. However, contrary to his disappointing experience, I have found that they provide my family with a useful amount of hot water. In our system, the solar energy is used to heat a store of water, which has no other source of heat. Mains-pressure cold water passes through this store via a heat exchanger, removing heat from it and warming up. If the water becomes warm enough, an unpowered thermostatic valve allows it to go straight to the hot taps (mixing it with cold if it is too hot). However, if it is not hot enough, then the water is directed first through our previously installed gaspowered combination boiler and then to the taps.

    The Thunderstorm Overflight Program is being conducted by NASA, NOAA, and universities to evaluate the feasibility of making meaningful measurements of lightning parameters from an orbiting platform above thunderstorms. A NASA instrumented U-2 high-altitude research aircraft was used during the summer of 1979 and spring of 1980 to collect data over the tops of the thunderstorms while ground-based measurements were being made simultaneously. Test sites at Langmuir Laboratory, Socorro, N. Mex., and the National Severe Storms Laboratory, Norman, Okla. were used for this program. Additional flights are planned for the spring and summer of 1981. Data from the NASA U-2 flights will also be used to interpret measurements made during the Nighttime/Daytime Optical Survey Lightning Experiment to be flown on the Space Shuttle in late 1981.

    The paper describes the results from a modeling effort using two energy balance approaches for estimating latent heat fluxes and daily evapotranspiration. The two models are (1) a one-layer empirically based energy balance model (OLEM) described by Chavez et al, (2005) and (2) the Two-source model (TSM) by Norman et al, (1995) modified by Li et al, (2005). The instantaneous derived latent heat fluxes are extrapolated to daily values of evapotranspiration using different approaches and over time in between Landsat TM acquisition dates. The energy balance model results are used as inputs to a soil moisture balance model. Comparisons of the remotely sensed fluxes with tower measured fluxes are conducted along with comparisons between modeled and measured soil moisture during the intensive period of the SMACEX study (Kustas et al, 2005), in a rain fed corn and soybean cropped area close to Ames, Iowa.

    The therapeutic efficacy of oral N-acetylcysteine (NAC) and ambroxol as compared with the effect of placebos was studied in 36 cystic fibrosis (CF) patients with mild to moderate pulmonary disease. The patients were randomly assigned to one of three regimens, matched on the basis of age and Chrispin-Norman scores. The trial was conducted over a period of 12 weeks. Patients were assessed clinically and by extensive pulmonary function techniques (body-plethysmography, maximal expiratory flow-volume curves, trapped air determination). Although no clinical differences could be observed between the three groups, significant impairment in the placebo group was found for trapped air and FEV1 when compared to the active groups, suggesting a therapeutic effect of ambroxol and NAC in CF.

    Uranium is the most political of all the elements, the material for the production of both the large amounts of electricity and the most destructive weapons in the world. The problems that its dual potential creates are only now beginning to become evident. Author Norman Moss looks at this situation and sheds light on many of the questions that emerge. The nuclear issue always comes back to how much uranium there is, what can be done with it, and which countries have it. Starting with a concise history of uranium and explaining its technology in terms the nonspecialist can understand, The Politics of Uranium considers the political issues that technical arguments obscure. It tells the little-known story of the international uranium cartel, explains the entanglements of governments with the uranium trade, and describes the consequences of wrong decisions and blunders-especially the problems of nuclear waste. It also examines the intellectual and emotional roots of the anti-nuclear movement.

    Scanning probe microscopes are perhaps best known for being able to image individual atoms in real space. A practical complication of this extreme spatial sensitivity is that these instruments are also extremely sensitive to mechanical vibrations; to approach ultimate levels of performance, these microscopes must therefore be operated in an environment with an extremely low level of mechanical vibrations. In this work, the specification, design and commissioning of a new ultra-low-vibration facility recently completed at the University of British Columbia is presented. Based on the pneumatically-suspended inertial slab concept used at NIST's Gaithersburg facilityfootnotetextHal Amick, Bea Sennewald, Norman C.

    2015-01-01

    Human rights, including the right to health, are grounded in protecting and promoting human dignity. Although commitment to human dignity is a widely shared value, the precise meaning and requirements behind the term are elusive. It is also unclear as to how a commitment to human dignity translates into specific human rights, such as the right to the highest attainable standard of health, and delineates their scope and obligations. The resulting lack of clarity about the foundations of and justification for the right to health has been problematic in a number of ways. This article identifies the strengths of and some of the issues with the grounding of the right to health in human dignity. It then examines ethical and philosophical expositions of human dignity and several alternative foundations proposed for the right to health, including capability theory and the work of Norman Daniels, to assess whether any offer a richer and more adequate conceptual grounding for the right to health.

    Collaborative activities between operational forecasters and meteorological research scientists have the potential to provide significant benefits to both groups and to society as a whole, yet such collaboration is rare. An exception to this state of affairs is occurring at the National Severe Storms Laboratory (NSSL) and Storm Prediction Center (SPC). Since the SPC moved from Kansas City to the NSSL facility in Norman, Oklahoma in 1997, collaborative efforts between researchers and forecasters at this facility have begun to flourish. This article presents a historical background for this interaction and discusses some of the factors that have helped this collaboration gain momentum. It focuses on the 2001 Spring Program, a collaborative effort focusing on experimental forecasting techniques and numerical model evaluation, as a prototype for organized interactions between researchers and forecasters. In addition, the many tangible and intangible benefits of this unusual working relationship are discussed.

    Mast-feeding systems once formed the mainstay of pork production across Europe, but have now largely been forgotten. One of the earliest farming practices, it allowed people to fatten pigs on an otherwise wasted resource. Mast feeding was vital in the ancient world: Rome, Saxon England and the Normans all relied heavily on woodland pigs. As time and technology advanced, mast systems became outmoded and fell into disuse. However, recent public interest in improved animal welfare and sustainable agriculture, combined with anecdotal reports of improved flavour, has once again brought mast feeding into the spotlight. This article chronicles the changes in popularity and perception of mast-feeding systems throughout history, and uses the historical perspective to outline a possible future for woodland pigs.

    Palliative care serves both as an integrated part of treatment and as a last effort to care for those we cannot cure. The extent to which palliative care should be provided and our reasons for doing so have been curiously overlooked in the debate about distributive justice in health and healthcare. We argue that one prominent approach, the Rawlsian approach developed by Norman Daniels, is unable to provide such reasons and such care. This is because of a central feature in Daniels' account, namely that care should be provided to restore people's opportunities. Daniels' view is both unable to provide pain relief to those who need it as a supplement to treatment and, without justice-based reasons to provide palliative care to those whose opportunities cannot be restored. We conclude that this makes Daniels' framework much less attractive. PMID:25689627

    This sixth quarterly report describes the activities and accomplishments of the research team at the University of Oklahoma, Norman, Oklahoma, related to the project entitled ``Combustion of Pulverized Coal in Vortex Structures`` during the period January 1, 1995 to March 31, 1995. The work performed in this quarter consisted of the following four tasks: (1) design and fabrication of a computer-driven traversing mechanism for traversing LDV transmitter and receiving optics, (2) color schlieren photography, (3) presenting a report in the panel-review meeting in Pittsburgh, (4) installation of additional safety devices in response to the letter of Dr. Sean Plasynski, and (5) streamwise velocity measurement in the isothermal heterogeneous shear layer with nonreacting particles using LDV. In the next quarter, we plan to continue this work with heated shear layers in which particles undergo pyrolysis. Flow visualization and mean velocity field measurement instrumentation will continue as the major experimental techniques.

  7. When the going gets tough the beautiful get going: aesthetic appeal facilitates task performance.

    The current studies examined the effect of aesthetic appeal on performance. According to one hypothesis, appeal would lead to overall decrements or enhancements in performance [e.g. Sonderegger & Sauer, (Applied Ergonomics, 41, 403-410, 2010)]. Alternatively, appeal might influence performance only in problem situations, such as when the task is difficult [e.g. Norman, (2004)]. The predictions of these hypotheses were examined in the context of an icon search-and-localisation task. Icons were used because they are well-defined stimuli and pervasive to modern everyday life. When search was made difficult using visually complex stimuli (Experiment 1), or abstract and unfamiliar stimuli (Experiment 2), icons that were appealing were found more quickly than their unappealing counterparts. These findings show that in a low-level visual processing task, with demand characteristics related to appeal eliminated, appeal can influence performance, especially under duress. PMID:25595208

    This two hour special workshop was held during the 2012 ASP conference in Tucson. There are a variety of reasons that science education needs to reach out to culturally diverse audiences. Each culture, and each individual community, has its own challenges; each brings special insight to science. What does the research say about engaging these different audiences? How can science educators attract and sustain programs with various cultures? How do the needs of our audiences vary with culture and within communities? Moderators Shupla, Sanlyn, and Peticolas invited a variety of presenters with expertise to share their experiences: Salvador Acevado, David Begay, Michelle Higgins, Bryan Mendez, and Dara Norman. During the first hour, presenters shared a variety of best practices for engaging and supporting culturally diverse audiences; in the second hour, participants and presenters discussed specific programmatic challenges and possible directions.

  9. Magnitude systems in old star catalogues

    The current system of stellar magnitudes originally introduced by Hipparchus was strictly defined by Norman Pogson in 1856. He based his system on Ptolemy's star catalogue, the Almagest, recorded in about AD137, and defined the magnitude-intensity relationship on a logarithmic scale. Stellar magnitudes observed with the naked eye recorded in seven old star catalogues were analyzed in order to examine the visual magnitude systems. Although psychophysicists have proposed that human visual sensitivity follows a power-law scale, it is shown here that the degree of agreement is far better for a logarithmic scale than for a power-law scale. It is also found that light ratios in each star catalogue are nearly equal to 2.512, if the brightest (1st magnitude) and the faintest (6th magnitude and dimmer) stars are excluded from the study. This means that the visual magnitudes in the old star catalogues agree fully with Pogson's logarithmic scale.

    The present system of astronomical magnitudes was created as an inverse scale by Claudius Ptolemy in about 140 A.D. and was defined to be logarithmic in 1856 by Norman Pogson, who believed that human eyes respond logarithmically to the intensity of light. Although scientists have known for some time that the response is instead a power law, astronomers continue to use the Pogson magnitude scale. The peculiarities of this system make it easy for students to develop numerous misconceptions about how and why to use magnitudes. We present a useful exercise in the use of magnitudes to derive a cosmologically interesting quantity (the mass-to-light ratio for spiral galaxies), with potential pitfalls pointed out and explained.

    The B-57B Severe Storms Flight Program gathers data to characterize atmosphere anomalies such as wind shear, turbulence, and microbursts at altitudes up to 1000 feet (300 meters). These data are used to enhance the knowledge of atmospheric processes, to improve aviation safety, to develop systems technology and piloting technique for avoiding hazards and to increase the understanding of the causes of related aircraft accidents. The NASA Dryden Flight Research Facility B-57B aircraft has participated in several severe storms data collection programs such as the Joint Airport Weather Studies (JAWS) located in Denver, Colorado area, Operation Rough Rider located in the Norman, Oklahoma area with the National Severe Storms Laboratory, and Mountain and desert turbulence in the Edwards Air Force Base, California area. Flight data are presented from flights which encountered the wind shear, turbulence and microburst anomalies. These flight results are discussed and some conclusions are made relating to these atmospheric anomalies.

    The early astrophysicist Norman Lockyer was both editor of the journal Nature from its creation in 1869 and for the following five decades, and an early practioner of the new astronomy. He frequently used the journal to expound his scientific theories, report on his work and send news home while on expeditions. I look into the particular visual culture of astrophysics developed by Lockyer in Nature, its evolution at a time of rapid development both of the techniques of astrophysical observation and visualization and of the techniques of image reproduction in print. A study of the use and reuse of visual materials in different settings also makes it possible to sketch the circulating economy of Lockyer's images and the ways in which he put himself forward as a scientist, at a time when he was advocating the State support of research and scientists and helping create the modern scientific journal.

    One critical step in addressing and resolving the problems associated with human errors is the development of a cognitive taxonomy of such errors. In the case of errors, such a taxonomy may be developed (1) to categorize all types of errors along cognitive dimensions, (2) to associate each type of error with a specific underlying cognitive mechanism, (3) to explain why, and even predict when and where, a specific error will occur, and (4) to generate intervention strategies for each type of error. Based on Reason's (1992) definition of human errors and Norman's (1986) cognitive theory of human action, we have developed a preliminary action-based cognitive taxonomy of errors that largely satisfies these four criteria in the domain of medicine. We discuss initial steps for applying this taxonomy to develop an online medical error reporting system that not only categorizes errors but also identifies problems and generates solutions.

    Shortly after the Fukushima reactor accident, we collected rainwater samples in the San Francisco Bay area. Subsequent gamma-ray counting revealed the presence of volatile short-lived fission fragments such as ^131, 132I, ^132Te, and ^134,137 Cs [1]. Recently, we have searched for the presence of the long-lived fission fragment ^90Sr in these same rainwater samples. To chemically separate Sr, a small amount of stable Sr carrier was dissolved in each rainwater sample. Potassium carbonate was then added to precipitate SrCO3. The precipitate was filtered, dried, and then beta counted using a planar Ge detector. Results from these measurements will be presented and compared to the levels of other fission fragments previously observed in the rainwater. [4pt] [1] E. B. Norman, C. T. Angell, P. A.

    Harrison, Albert A.

    Few topics ignite the imagination as do the prospects of encountering extraterrestrial life - and what this may mean for individuals, societies, and cultures. Until recently speculation fell largely within the realms of philosophy, science fiction, and UFO studies. By 1960, however, the theoretical feasibility of interstellar transmissions coupled with Frank Drake's initial empirical search, Project Ozma, established a need to put such speculation on a firmer footing. Drake's work had gained the attention of Donald Norman, a psychologist who was developing a report on the peaceful uses of outer space for the US Congress. Whereas most of this report dealt with topics such as communications satellites, remote sensing, and human space exploration, portions dwelled on the possible implications of the discovery.

    This paper provides an intercomparison of the HPA male and female models, NORMAN and NAOMI with the National Institute of Information and Communications Technology (NICT) male and female models, TARO and HANAKO. The calculations of the whole-body SAR in these four phantoms were performed at the HPA, at NICT and at the Nagoya Institute of Technology (NIT). These were for a plane wave with a vertically aligned electric field incident upon the front of the body from 30 MHz to 3 GHz for isolated conditions. As well as investigating the general differences through this frequency range, particular emphasis was placed on the assumptions of how dielectric properties are assigned to tissues (particularly skin and fat) and the consequence of using different algorithms for calculating SAR at the higher frequencies.

But even beyond specific measurements and results, the fruitfulness and practice of spectroscopy had important ramifications on a more abstract level. This paper will discuss ways in which spectroscopy inspired or boosted new theories of the atom, life, and the Universe; redrew the boundaries among scientific disciplines; demonstrated the unity of terrestrial and celestial physical laws; changed what counted as scientific knowledge; and even revealed divine mysteries. Scientists and science writers from the first half-century of astronomical spectroscopy will be discussed, including James Clerk Maxwell, William Crookes, John Tyndall, Agnes Clerke, William Huggins and Norman Lockyer.

  1. Numerically simulated cardiac exposure to electric current densities induced by TASER X-26 pulses in adult men

    There is still an ongoing debate whether or not electronic stun devices (ESDs) induce cardiac fibrillation. To assess the ventricular fibrillation risk of law enforcing electronic control devices, quantitative estimates of cardiac electric current densities induced by delivered electric pulses are essential. Numerical simulations were performed with the finite integration technique and the anatomical model of a standardized European man (NORMAN) segmented into 2 mm voxels and 35 different tissues. The load-dependent delivery of TASER X-26 pulses has been taken into account. Cardiac exposure to electric current densities of vertically and horizontally aligned dart electrodes was quantified and different hit scenarios compared. Since fibrillation thresholds critically depend on exposed volume, the provided quantitative data are essential for risk assessment. The maximum cardiac rms current densities amounted to 7730 A m-2. Such high current densities and exposed cardiac volumes do not exclude ventricular fibrillation.

    If an electromagnetic field is incident normally onto a perfectly conducting ground plane, the field is reflected back into the domain. This produces a standing wave above the ground plane. If a person is present within the domain, absorption of the field in the body may cause problems regarding compliance with electromagnetic guidelines. To investigate this, the whole-body averaged specific energy absorption rate (SAR), localised SAR and ankle currents in the voxel model NORMAN have been calculated for a variety of these exposures under grounded conditions. The results were normalised to the spatially averaged field, a technique used to determine a mean value for comparison with guidelines when the field varies along the height of the body. Additionally, the external field values required to produce basic restrictions for whole-body averaged SAR have been calculated. It was found that in all configurations studied, the ICNIRP reference levels and IEEE MPEs provided a conservative estimate of these restrictions.

    This report was first published in the Journal in 1966 (Vol. 19, p. 411). In its reprinted form it has been abridged by omitting detailed recommendations for the establishment of separation areas and recommended routes in the Baltic, the North Sea, the Dover Strait, and the English Channel to Gibraltar. These recommendations were included in the original section 7. The report is followed by comments from Norman Cockcroft.In 1961 the Institutes of Navigation in Great Britain and France, with the Deutsche Gesellschaft fur Ortung und Navigation, formed a representative Working Group to go into the question of regulating traffic in converging areas at sea with particular reference to the Dover Strait. The Group's Report, which was published in October 1962, made certain proposals for routing traffic in the area which were accepted, in April 1964, by the Maritime Safety Committee of the Inter-Governmental Maritime Consultative Organization.

    With the Cold War fading into history, economic competitiveness becoming the watchwords of the decade, and the space race against the Russians turning into probable cooperation, NASA is struggling to redefine its role. On November 16, the Senate Commerce Subcommittee on Science, Technology and Space invited NASA Administrator Daniel Goldin, Martin Marietta CEO Norman Augustine, and Robert Frosch of Harvard University's John F. Kennedy School of Government to offer their thoughts on NASA's plans, priorities, and budgetary difficulties. Augustine, who chaired the Committee on the Future of the U.S. Space Program in 1990, posed two questions: What does America want its space program to be, and can the country afford to pay for the program it wants? He stated bluntly that if the answers were incompatible, “we are unlikely to have a satisfactory program.”

    A new marine gastrotrich species of the genus Cephalodasys is described from shallow sublittoral coralline sand sampled between Lee Stocking Island and Norman's Pond Cay (Exuma Cays), Bahamas. Cephalodasys interinsularis n. sp. reaches a body length of 471 µm and is characterized by a new combination of characters including six total anterior adhesive tubes and five pairs of ventrolateral adhesive tubes. The new species is morphologically similar to C. swedmarki but can be distinguished by the different number of anterior adhesive tubes, the spatial arrangement of the ventrolateral adhesive tubes, and a shorter pharynx. We provide an updated diagnosis of the genus and a determination key to all known species of Cephalodasys. C. interinsularis n. sp. is the third known species of Cephalodasys from the Caribbean marine province. PMID:25947742

    Objective Connectionist theories of brain function took hold with the seminal contributions of Norman Geschwind a half century ago. Modern neuroimaging techniques have expanded the scientific interest in the study of brain connectivity to include the intact as well as disordered brain. Method In this review, we describe the most common techniques used to measure functional and structural connectivity, including resting state functional MRI, diffusion MRI, and electroencephalography and magnetoencephalography coherence. We also review the most common analytical approaches used for examining brain interconnectivity associated with these various imaging methods. Results This review presents a critical analysis of the assumptions, as well as methodological limitations, of each imaging and analysis approach. Conclusions The overall goal of this review is to provide the reader with an introduction to evaluating the scientific methods underlying investigations that probe the human connectome.

    Continuous observations from December 1, 1993 through November 30, 1995 were made at the ACTS Propagation Terminal on the roof of the Sarkeys Energy Center at the University of Oklahoma in Norman, Oklahoma. Beacon and radiometer observations were combined to calibrate the beacon system for the estimation of total attenuation (attenuation relative to free space) and attenuation relative to clear sky (gaseous absorption component removed). Empirical cumulative distributions (edf's) were compiled for each month of observation and for each year. The annual edf's are displayed in the figures, the monthly and annual edf's are listed in the tables. The tables are organized by blocks and pages within a block. The blocks correspond to the headings in the edf files generated by the ACTS Preprocessing (actspp) software and contained in the fourth disk in the set of ACTS Propagation Experiment CD-ROMs generated by the University of Texas.

    1994-05-01

    In previous work, Balsara and Norman (1992), we had focussed on simulating narrow angle tailed radio sources as fluid beams that are bent by the ram pressure of a cross flowing ICM. This allowed a comparison with several observable attributes of NAT sources. In particular we were able to make estimates of bending rate, beam profile, radial evolution and formation and interspacing of knots. The previous work suffered from the fact that the ISM of the host galaxy was not represented. In this work we remove that restriction by representing the host galaxy's ISM self-consistently using the prescription given in Balsara, Livio and O'Dea (1994). We then run jets through it and compare with observations.

    Moral rules provide the baseline for ethics, proscribing unacceptable behavior; moral ideals inspire us to act in ways that improve the human condition. Whatever the moral ideals for pure research, science has a practical side so it is important to find a moral ideal to give guidance to more applied research. This article presents a moral ideal for use-inspired research based on Norman Care's idea of shared-fate individualism This ideal reflects the observation that all human lives, both present and future are tightly coupled and, as a result, research projects should be chosen, where possible, with the goal of service to others. Together with the ideals of the habit of truth and the gift economy, shared-fate individualism provides the basis for a humane ethics of science. PMID:17717730

    Calculations of localised SAR in the legs and arms have been performed in a female voxel phantom, NAOMI. A finite difference method was used to solve the quasistatic potential equation from 0.1 to 80 MHz for a unit current injected into a limb. The relationship between limb current and SAR has been investigated. The values of localised SAR in the leg as a function of applied plane wave electric field are also predicted from the knowledge of limb currents calculated by the finite-difference time-domain (FDTD) method for whole-body exposure. Comparisons are made with the results of previous work for the normalised male model, NORMAN, and the implications for electromagnetic guidelines are discussed. PMID:16565198

    Norman Daniels's new book, Just Health, brings together his decades of work on the problem of justice and health. It improves on earlier writings by discussing how we can meet health needs fairly when we cannot meet them all and by attending to the implications of the socioeconomic determinants of health. In this article I return to the core idea around which the entire theory is built: that the principle of equality of opportunity grounds a societal obligation to meet health needs. I point, first, that nowhere does Daniels say just what version of that principle he accepts. I then proceed to construct a principle on his behalf, based on a faithful reading of Just Health. Once we actually nail down the principle, I argue, we will find that there are two problems: it is implausible in itself, and it fails to ground a societal obligation to meet health needs.

    From 1936 to 1961 astronomers at the Norman Lockyer Observatory at Sidmouth England documented six major rain-water borne invasions of bacteria capable of rapidly liquefying astronomical photographic emulsions. Based on an American suggestion that endemic influenza originates in the upper atmosphere of Venus and gets blown by the solar wind to Earth, they checked and found strong positive correlation between Venus inferior conjunctions, concurrent geomagnetic storms, and their microbial invasions. This presentation highlights further research into the original premise about microbial transfers from Venus to Earth and their subsequent global distibution via long-range air-mass movements. The 1918 influenza pandemic is used as a starting point for this followup study. Findings to date will be summarized. Key Words: Exobiology, aerobiology

  18. Resource allocation in health care and the role of personal autonomy.

    Gandjour, A

    2015-03-01

    Resource allocation decisions in health care require the consideration of ethical values. Major ethical theories include Amartya Sen's capability approach, Norman Daniels's theory of justice for health, and preference utilitarian theory. This paper argues that while only preference utilitarian theory explicitly considers the impact of an individual's actions on others, all 3 theories agree in terms of providing individual autonomy. Furthermore, it shows that all 3 theories emphasise the role of informed preferences in securing individual autonomy. Still, stressing personal autonomy has limited direct implications for priority setting. 2 priority rules for resource allocation could be identified: 1) to give priority to patients with mental disability (over those with pure physical disability); and 2) to give priority to patients with a large expected loss of autonomy without treatment.

    Simarski, Lynn Teo

    The forced resignation of NASA chief Richard Truly on February 12 is widely seen as having weakened the agency at a critical time, just as Congress has begun considering this year's federal budget request. Members of a House space panel expressed dismay at Truly's ouster by the White House, when the agency head appeared February 19 at the year's first NASA budget hearing. Several legislators suggested that the dismissal strengthened the hand of the National Space Council, which is headed by Vice President Dan Quayle.“It angers me to think that NASA, which has inspired generations of Americans, is being turned into a public relations tool for the rehabilitation of Dan Quayle,” said Norman Y. Mineta (D-Calif.) at the hearing of the Space Subcommittee of the House Science, Space, and Technology Committee. Mineta's charge that the White House is using NASA as a “political poker chip” was echoed repeatedly by other legislators during the hearing.

    Biofouling programs at Duke Power Company (DPC) can be traced to the invasion of the Catawba River system by Corbicula in 1968. Raw water systems at Plant Allen, a coal-fired station on Lake Wylie, became heavily infested by clams during the 1970s. Development of programs was accelerated as a result of the shutdown of Catawba nuclear station (CNS) on lake Wylie in 1986 due to clam infestations in safety-related systems, increased biofouling problems at McGuire nuclear station (MNS) on lake Norman, and by the issuance of the US Nuclear Regulatory Commission's (NRC's) Generic Letter (GL) 89-13 (issued in 1989). Historical data were reviewed to identify pertinent questions, and a refined, multifaceted Corbicula monitoring plan was developed. This plan was implemented at CNS and MNS in 1989.

    The EPA Office of Air Quality Planning and Standards is currently evaluating the performance of models in several categories. As part of that program, eight short-term long-range transport models have been tested with two data bases representing tracer releases. These releases involve transport and dispersion over essentially flat terrain. The Oklahoma data base (Ferber et al., 1981) includes two releases of a perfluorocarbon tracer from Norman, Oklahoma. The Savannah River Plant data base includes 15 experiments (data sets) from a continuous elevated release of krypton-85. The evaluation procedure used was based primarily on the American Meteorological Society (AMS) statistics (Fox, 1981). These results were supplemented by several graphical comparisons which were used to interpret the causes of model/data discrepancies.

  3. The changing face of heart transplantation.

    It has been 40 years since the first human-to-human heart transplant performed in South Africa by Christiaan Barnard in December 1967. This achievement did not come as a surprise to the medical community but was the result of many years of early pioneering experimental work by Alexis Carrel, Frank Mann, Norman Shumway, and Richard Lower. Since then, refinement of donor and recipient selection methods, better donor heart management, and advances in immunosuppression have significantly improved survival. In this article, we hope to give a perspective on the changing face of heart transplantation. Topics that will be covered in this review include the changing patient population as well as recent advances in transplantation immunology, organ preservation, allograft vasculopathy, and immune tolerance.

  4. Resonance behaviour of whole-body averaged specific energy absorption rate (SAR) in the female voxel model, NAOMI

    2005-09-01

    Finite-difference time-domain (FDTD) calculations have been performed of the whole-body averaged specific energy absorption rate (SAR) in a female voxel model, NAOMI, under isolated and grounded conditions from 10 MHz to 3 GHz. The 2 mm resolution voxel model, NAOMI, was scaled to a height of 1.63 m and a mass of 60 kg, the dimensions of the ICRP reference adult female. Comparison was made with SAR values from a reference male voxel model, NORMAN. A broad SAR resonance in the NAOMI values was found around 900 MHz and a resulting enhancement, up to 25%, over the values for the male voxel model, NORMAN. This latter result confirmed previously reported higher values in a female model. The effect of differences in anatomy was investigated by comparing values for 10-, 5- and 1-year-old phantoms rescaled to the ICRP reference values of height and mass which are the same for both sexes. The broad resonance in the NAOMI child values around 1 GHz is still a strong feature. A comparison has been made with ICNIRP guidelines. The ICNIRP occupational reference level provides a conservative estimate of the whole-body averaged SAR restriction. The linear scaling of the adult phantom using different factors in longitudinal and transverse directions, in order to match the ICRP stature and weight, does not exactly reproduce the anatomy of children. However, for public exposure the calculations with scaled child models indicate that the ICNIRP reference level may not provide a conservative estimate of the whole-body averaged SAR restriction, above 1.2 GHz for scaled 5- and 1-year-old female models, although any underestimate is by less than 20%.

  5. Evaluation of sulfate reduction at experimentally induced mixing interfaces using small-scale push-pull tests in an aquifer-wetland system

    This paper presents small-scale push-pull tests designed to evaluate the kinetic controls on SO42 - reduction in situ at mixing interfaces between a wetland and aquifer impacted by landfill leachate at the Norman Landfill research site, Norman, OK. Quantifying the rates of redox reactions initiated at interfaces is of great interest because interfaces have been shown to be zones of increased biogeochemical transformations and thus may play an important role in natural attenuation. To mimic the aquifer-wetland interface and evaluate reaction rates, SO42 --rich anaerobic aquifer water (??? 100 mg / L SO42 -) was introduced into SO42 --depleted wetland porewater via push-pull tests. Results showed SO42 - reduction was stimulated by the mixing of these waters and first-order rate coefficients were comparable to those measured in other push-pull studies. However, rate data were complex involving either multiple first-order rate coefficients or a more complex rate order. In addition, a lag phase was observed prior to SO42 - reduction that persisted until the mixing interface between test solution and native water was recovered, irrespective of temporal and spatial constraints. The lag phase was not eliminated by the addition of electron donor (acetate) to the injected test solution. Subsequent push-pull tests designed to elucidate the nature of the lag phase support the importance of the mixing interface in controlling terminal electron accepting processes. These data suggest redox reactions may occur rapidly at the mixing interface between injected and native waters but not in the injected bulk water mass. Under these circumstances, push-pull test data should be evaluated to ensure the apparent rate is actually a function of time and that complexities in rate data be considered. ?? 2007 Elsevier Ltd.

    Norman Windom, the chairman of Tiverton Media, may not know much about the world of popular music, but he does fancy himself a careful planner and a superb judge of managerial talent. That's why he's been grooming COO Sean Kinnane, a Wharton-minted numbers man, to take over an important division, Aleph Records, and one day Tiverton itself. But Derek Solomon, Aleph's 68-year-old CEO and founder, remains a creative force and a father figure to the label's artists. What's more, he's touchy about anything that might slow down Aleph's responses to the market's ever-shifting preferences--or that might call into question his indispensability. Though Sean dutifully participates in Tiverton's broad-based and elaborate executive development plan, he senses that Aleph's future leadership structure is uncertain. As impatient as he is ambitious, he announces that he's leaving Tiverton for more suitable pastures. Several of his associates, also unsure about their fate within Aleph, are following him out the door. In one fell swoop, they've torn Norman's proud succession plan apart. What kind of plan should the board adopt going forward? Commenting on this fictional case study are Francis N. Bonsignore, a senior vice president at Marsh & McLennan; Michelle L. Buck, a clinical associate professor of management and organizations at Northwestern's Kellogg School of Management; Jon Younger, who heads leadership development at National City Corporation, a financial holding company in Cleveland; and Thomas Leppert, the chairman and CEO of the Turner Corporation, a large construction company in Dallas.

  7. A Sample from an Ancient Sea of Impact Melt

    Taylor, G. J.

    2016-06-01

    Sophisticated computer modeling of the formation of lunar multi-ringed basins by impact indicate that substantial volumes of impact melt are produced, leading to melt bodies hundreds of kilometers in diameter and tens of kilometers deep. The impressively large bodies of magma created by the impact of a projectile 50 to 300 kilometers across might have differentiated, producing a zoned body with denser minerals concentrated towards the bottom and less dense minerals concentrated near the top, a process called fractional crystallization. Marc Norman (Australian National University) and colleagues at the University of Tennessee and the Johnson Space Center have studied a sample (67955) collected in the lunar highlands during the Apollo 16 mission. The overall texture, composition, and mineralogy of a clast (a fragment) in the rock indicate that it formed as an accumulation of crystals from a magma that was enriched in trace elements. Mineral compositions and crystal intergrowths suggest a similar depth of origin to lunar igneous rocks that formed more than 10 kilometers deep in the lunar crust, implying an impact melt pool at least as deep. Such a deep melt pool would have formed in an impact basin the size of Orientale, a multi-ringed basin whose inner ring is 480 kilometers across. Norman and co-workers also determined from samarium and neodymium isotopes that the igneous clast is 4.2 billion years old, clearly older than the typical age of 3.8-3.9 billion years assigned to visible lunar basins. The authors conclude that the clast in 67955 is a sample of a differentiated impact melt sea formed in an impact basin on the nearside of the Moon 4.2 billion years ago. The rock was part of a pile of ejecta thrown to the Apollo 16 site, possibly by the impact event that excavated the Imbrium basin.

    It is the oldest church in the city after the cathedral. It is among the purest examples of Romanesque. It was founded in 1074 and expenses for its construction helped the inhabitants of the agricultural hamlets of the Cirignano, Pacciano and Zappino. The church was dedicated to St. Adoeno Dado, bishop of Rouen, protector of Norman, because , according to tradition, the building also participated Norman soldiers. San Adoeno church has a façade at cusp with a truncated tympanum , crowned by an eagle. In the centre of the façade there is a rose ornament surrounded by four lions and a statue of St. Adoeno ( Figs. A to I ). On the outside walls of this Abbey many graffiti, produced by different coloured spray paints were found. After the usual photographical tests some Laser Paint Removal trials were executed to verify the damage threshold of the calcareous stony substrate as well as the possibility to ablate these paints by a Nd - YAG laser in Q-Switch mode. Even if all the classical four laser paint ablation techniques were employed some paints showed a great difficulty to be removed from the substrate. For these ones it was necessary to increase at maximum both the energy per pulse and the fluence value for obtaining some acceptable result but the substrate looked turned pale. It was decided to remove a small amount of these paints and subject to chemical analysis for determining whether they were acrylic based. At the same time it was investigated on the type of limestone substrate that appeared more porous and less hard on the surface than the common local limestone marble basin, that is, Trani or Bisceglie. So, on the light of these investigations, the possible solution for this hard laser ablation problem was carried out with an acceptable final result.

  9. Remote Dynamic Triggering of Earthquakes in Three Canadian Shale Gas Basins Based on a Multi-station Matched-filter Approach with Dense Station Coverage

    Earthquakes triggered by remote, transient stresses may indicate critical ambient stress conditions on host faults, independent of their proximity to plate boundaries. Here, we investigate dynamic triggering of three sedimentary basins in Canada where seismic station coverage has been increased to monitor anticipated increases in fluid injection activity: northeast British Columbia and western Alberta, the Norman Wells area of the Northwest Territories, and northeast New Brunswick. We select triggering mainshock candidates satisfying the following criteria: Ms > 6, and local peak ground velocity exceeding 0.01 cm/s. We find 31 mainshocks in northeast British Columbia/western Alberta, 9 in Norman Wells, and 4 in New Brunswick during increased station operation. We will investigate seismicity rates in 10-day windows before and after each mainshock using local earthquake catalog data and uncataloged events detected using a multi-station matched-filter approach on continuous waveform data. The multi-station matched-filter method detects earthquakes by cross-correlating known earthquakes with continuous data and declaring events when correlation values of combined stations exceed a pre-set threshold. After determining seismicity rates in the 20-day windows surrounding each mainshock, we will use aβ-statistic and p-value to quantify if statistically significant triggering has occurred. Where triggering occurs, calculations of triggered earthquake focal mechanisms may help explain how receiver pre-existing faults become critically stressed, and what physical factors are directly correlated with dynamic triggering. Cases of observed triggering may imply that the seismic response to injection activity could be more intense than in regions without remote dynamic triggering. Alternatively, if triggering occurs but the seismic response to injection activity is limited, it could imply that hydraulic communication with basement faults is key for inducing earthquakes.

  10. Elements in cottonwood trees as an indicator of ground water contaminated by landfill leachate

    Ground water at the Norman Landfill Research Site is contaminated by a leachate plume emanating from a closed, unlined landfill formerly operated by the city of Norman, Oklahoma, Ground water contaminated by the leachate plume is known to be elevated in the concentration of many, organic and inorganic constituents. Specific conductance, alkalinity, chloride, dissolved organic carbon, boron, sodium, strontium, and deuterium in ground water are considered to be indicators of the leachate plume at this site. Leaf samples of broad-leafed cottonwood, Populus deltoides, were collected from 57 sites around the closed landfill. Cottonwood, a phreatophyte or “well plant,” functions as a & surrogate well and serves as a ground water quality sampler. The leaf samples were combusted to ash and analyzed by instrumental neutron activation for 35 elements and by prompt-gamma instrumental neutron activation, for boron. A monitoring well was located within a few meters of a sampled cottonwood tree at 15 of the 57 sites, and ground water samples were collected from these monitoring wells simultaneously with a leaf sample. The chemical analyses of the ground water and leaf samples from these 15 sites indicated that boron, bromine, sodium, and strontium concentrations in leaves were significantly correlated with leachate indicator constituents in ground water. A point-plot map of selected percentiles indicated high concentrations of boron, bromine, and sodium in leaf ash from sites downgradient of the most recent landfill and from older landfills nearby. Data from leaf analysis greatly extended the known areal extent of the leachate plume previously determined from a network of monitoring wells and geophysical surveys. This phytosgeochemical study provided a cost-effective method for assessing the extent of a leachate plume from an old landfill. Such a method may be useful as a preliminary sampling tool to guide the design of hydrogeochemical and geophysical studies.

  11. Comparison of heat flux estimations from two turbulent exchange models based on thermal UAV data.

    Advantages of UAV (Unmanned Aerial Vehicle) data-collection, compared to more traditional data-collections are numerous and already well-discussed (Berni et al., 2009; Laliberte et al., 2011; Turner et al., 2012). However studies investigating the quality and applications of UAV-data are crucial if advantages are to be beneficial for scientific purposes. In this study, thermal data collected over an agricultural site in Denmark have been obtained using a fixed-wing UAV and investigated for the estimation of heat fluxes. Estimation of heat fluxes requires high precision data and careful data processing. Latent, sensible and soil heat fluxes are estimates through two models of the two source energy modelling scheme driven by remotely sensed observations of land surface temperature; the original TSEB (Norman et al., 1995) and the DTD (Norman et al., 2000) which builds on the TSEB. The DTD model accounts for errors arising when deriving radiometric temperatures and can to some extent compensate for the fact that thermal cameras rarely are accurate. The DTD model requires an additional set of remotely sensed data during morning hours of the day at which heat fluxes are to be determined. This makes the DTD model ideal to use when combined with UAV data, because acquisition of data is not limited by fixed time by-passing tracks like satellite images (Guzinski et al., 2013). Based on these data, heat fluxes are computed from the two models and compared with fluxes from an eddy covariance station situated within the same designated agricultural site. This over-all procedure potentially enables an assessment of both the collected thermal UAV-data and of the two turbulent exchange models. Results reveal that both TSEB and DTD models compute heat fluxes from thermal UAV data that is within a very reasonable range and also that estimates from the DTD model is in best agreement with the eddy covariance system.

    Noninvasive vascular testing has made a major contribution to the care of vascular surgery patients. This article a reflection on a 35-year corroborative association with Doctor Norman Rich, during which many of the advances in noninvasive vascular testing have been witnessed and effected. I served my vascular surgery fellowship under Doctor Rich in 1967-68 at Walter Reed Army Hospital. The only noninvasive vascular equipment then was a pencil probe Doppler. The value of the Doppler in the management of peripheral vascular disease that year and in determining limb viability in combat surgery in Vietnam the following year was established, and both experiences were published. Later, Doctor Rich established the annual Military Vascular Surgery Meeting and was appointed as the first Chair of the Department of Surgery at the Uniformed Services University for Health Sciences (USU). I entered private practice in Central California in 1976, and ultrasonic imaging was developed which allowed noninvasive examination of the carotid arteries. I then developed a protocol to screen for the three silent, immediate causes of stroke, employing a "a quick carotid scan" for carotid artery disease, a lead II rhythm strip for atrial fibrillation, and blood pressure determination for hypertension so that these common causes of strokes could be recognized and treated, and potentially prevent the majority of strokes. My association with USU, Doctor Rich, and others involved proved instrumental in initiating implementation of stroke prevention screening. The structure established at USU provides a means of establishing the protocol nationally. Noninvasive vascular testing is an addition to Medical Science that has led to significant improvements in individual patient care and that has the potential of allowing a major reduction in death and disability from stroke and other vascular diseases. Throughout a 35-year collaborative association with Doctor Norman M. Rich, I have witnessed and

  13. An overview of the systematics and biogeography of the flatfishes

    1997-11-01

    Until about 25 years ago, classification of the flatfishes was based on the Regan-Norman model. Beginning with the work of Amaoka in 1969, the order started to be analysed in finer detail, and in the 1980s many questions arose concerning flatfish phylogeny as expressed in the Regan-Norman model. Two of the major questions were whether the order is monophyletic and which groups within the order are monophyletic. Recent research has clarified many of these questions. Chapleau recently redefined the order based on shared derived characters, thus supporting the hypothesis of monophyly. The most recent classifications based on phylogenetic studies have split several of the traditionally recognized families. Some flatfish groups were shown to be monophyletic once certain species were excluded. As phylogenetic studies and work on the alpha-level taxonomy continue, we are beginning to see some very interesting biogeographic patterns. Some of these distribution patterns were not previously obvious due to polyphyly of some of the flatfish groups. There is still much work to be done on the systematics and biogeography of flatfishes. Some of the more important questions that remain to be addressed in future studies are the following. (1) What is the sister group of the order? (2) What is the sister group of the Southern Ocean Achiropsettidae? (3) What are the relationships of the remaining groups in the polyphyletic Pleuronectidae? (4) What are the relationships of certain genera that are excluded from recently redefined families? (5) What are the intergeneric relationships within monophyletic groups such as the Bothidae, Achiridae and Soleidae? A great deal of work at the alpha-taxonomic level with flatfishes is still needed. Especially in tropical areas, new species and great range extensions are routinely discovered. There is also a need for more ontogenetic studies of flatfishes.

  14. Geology and hydrocarbon potential of Mackenzie Valley, Northwest Territories

    1988-01-01

    In 1921, the first hole drilled for oil in the Mackenzie Valley, Northwest Territories, located on a natural seep at Norman Wells, made a major discovery in the Kee Scarp Limestone. Since then, in this remove 200,000 km/sup 2/ area, stretching from the Alberta border north to the Artic Circle, a further 500 exploratory wells have been drilled, and there has been one other commercial discovery. In the course of this exploration, however, hydrocarbon shows have been recorded in all the major sequences, ranging in age from Cambrian to Cretaceous. Deposition of Cambrian sands and evaporates was controlled by a series of linear arches that persisted until the Middle Devonian. In the Colville Hills area, a significant gas show has been found in basal sandstones overlain by evaporites. Throughout the Ordovician and Silurian, thick sequences of evaporities and carbonates were laid down. These sequences are generally nonprospective except in the southwest where a commercial gas field, Kotaneelee, is developed in fractured shoal carbonates. The Middle Devonian Hume and Kee Scarp formations represent periods of reef growth. The Kee Scarp has been extensively explored in the Mackenzie Valley, ad to date, Norman Wells has been the only success. The Hume formation has been less well explored and has potential in pinnacle reefs growing on a shoal carbonate bank. These Paleozoic sequences constitute the primary prospective zones in the Northwest Territories. The Mississippian is only locally preserved. Exploration in the Cretaceous will be primarily stratigraphic as structures have been complexly affected by the Laramide orogeny. In this relatively undrilled area, ongoing exploration has the potential to lead to major discoveries in the Mackenzie Valley.

    Uncertainty associated with predicting fate and transport of contaminants in the vadose zone is quite significant. This is predominantly due to the transient redox conditions and flow dynamics of the unsaturated zone that impacts the bioavailability or chemical lability of the contaminants before they reach groundwater. The hypothesis of this study is that regions with higher water flux will have higher redox potential. Specific objectives of the study are: 1) to identify positive and negative correlations amongst physical factors (e.g. flow rate, temperature, hydraulic conductivity) and chemical composition (e.g. rainwater chemistry, sorbed/aqueous concentrations, pH, Eh), and 2) to develop quantitative relationships using regression techniques with coupled HP1 (Hydrus-PHREEQC) model for factors identified as having strong associations. Flow experiments were conducted on two types of soil columns: homogeneous sand column with fine-grained alluvial sand from the banks of Canadian river, and layered sand-loam column with loamy soil collected from the wetland system of the Norman Landfill site. Norman Landfill is a closed municipal landfill site with prevalent organic contamination. For the second objective, Artificial Neural Networks will be trained using inputs (physical and chemical factors) and outputs (redox couples) obtained from soil column data and HP1, respectively. Preliminary results from lab experiments indicate decreased oxygen and nitrate, and higher iron-sulfide concentrations at the interface where hydraulic conductivity decreases from overlaying sand layer to loam soil. Higher redox activity at the interface layer suggests strong correlation between hydraulic gradient and redox potential. This is further qualified by the insignificant chemical concentration gradients (e.g. iron-sulfur coupling) observed in the homogeneous sand column.

    The absolute level of the global net radiation flux (NRF) is fixed at the level of [0.5-1.0] Wm-2 based on the ocean heat content measurements [1]. The space derived global NRF is at the same order of magnitude than the ocean [2]. Considering the atmosphere has a negligible effects on the global NRF determination, the surface global NRF is consistent with the values determined from space [3]. Instead of studying the absolute level of the global NRF, we focus on the interannual variation of global net radiation flux, which were derived from the PICARD-BOS experiment and its comparison with values over the same period but obtained from the NASA-CERES system and inferred from the ocean heat content survey by ARGO network.

Maps of iceberg density and potential locations subject to grounding complement sparse existing oceanographic and aerial field survey campaigns. The model suggests preferential pathways from the most important calving sources. Icebergs originating from Franz Josef Land have the largest spread over the domain. Simulations confirm the previously observed seasonal cycle of the southernmost extent of the icebergs. Strong interannual variability of the iceberg extent with a weak decreasing trend occurs, similar to the observed sea ice extent. Analysis of the atmospheric forcing reveals that years with anomalous northerly winds enhance the southward iceberg extension. Northerly winds also have a positive delayed impact on the iceberg extent. They limit the inflow of Atlantic Water into the Barents Sea and, therefore, its heat content the following year, increasing the mean age of icebergs and thus their potential extension. Finally, the model is able to reproduce the observed extreme iceberg extension southeast of the Barents Sea in May 2003.

    A scientific visit on Crystalline Rock Repository Development was held in the Czech Republic on September 24-27, 2012. The visit was hosted by the Czech Radioactive Waste Repository Authority (RAWRA), co-hosted by Sandia National Laboratories (SNL), and supported by the International Atomic Energy Agency (IAEA). The purpose of the visit was to promote technical information exchange between participants from countries engaged in the investigation and exploration of crystalline rock for the eventual construction of nuclear waste repositories. The visit was designed especially for participants of countries that have recently commenced (or recommenced) national repository programmes in crystalline host rock formations. Discussion topics included repository programme development, site screening and selection, site characterization, disposal concepts in crystalline host rock, regulatory frameworks, and safety assessment methodology. Interest was surveyed in establishing a %E2%80%9Cclub,%E2%80%9D the mission of which would be to identify and address the various technical challenges that confront the disposal of radioactive waste in crystalline rock environments. The idea of a second scientific visit to be held one year later in another host country received popular support. The visit concluded with a trip to the countryside south of Prague where participants were treated to a tour of the laboratory and underground facilities of the Josef Regional Underground Research Centre.

    Recently, optical luminescences from quartz and feldspar have been proposed to have great potential in low temperature thermochronology (<100°C). The present study aims to explore thermoluminescence (TL) of feldspar to determine cooling history of rock. The advantage of thermoluminescence over optical luminesce is single TL glow curve has different thermal and athermal stability at different temperature of the glow curve, which can be determined by computerized glow curve deconvolution (CGCD) method and estimation of rate of anomalous fading in the laboratory. The rock samples were collected from Alex Knob of Franz Josef glacier, New Zealand, which is expected to be one of the rapidly exhuming settings in Southern Alps. The natural luminescence levels, which are in the dynamic equilibrium because of competition between growth due to ambient radioactivity and decay due thermal and athermal loss, are determined using multiple aliquot regeneration (MAR) protocol. Multiple thermal signals with wide range of thermal stability, extracted from composite glow curve, particularly low temperature part which is more sensitive to ambient temperature, is promising for better constraint on late stage cooling history.

    Background Electron linear accelerators in medical radiotherapy have replaced cobalt and caesium sources of radiation. However, medical accelerators with photon energies over 10 MeV generate undesired fast neutron contamination in a therapeutic X-ray photon beam. Photons with energies above 10 MeV can interact with the atomic nucleus of a high-Z material, of which the target and the head of an accelerator consist, and lead to the neutron ejection. Results and conclusions. Our neutron dosimeter, composed of the LR-115 track etch detector and boron foil BN-1 converter, was calibrated on thermal neutrons generated in the nuclear reactor of the Josef Stefan Institute (Slovenia), and applied to dosimetry of undesirable neutrons in photon radiotherapy by the linear accelerator 15 MV Siemens Mevatron. Having considered a high dependence of a cross-section between neutron and boron on neutron energy, and broad neutron spectrum in a photon beam, as well as outside the entrance door to maze of the Mevatron, we developed a method for determining the effective neutron detector response. A neutron dose rate in the photon beam was measured to be 1.96 Sv/h. Outside the Mevatron room the neutron dose rate was 0.62 μSv/h. PACS: 87.52. Ga; 87.53.St; 29.40.Wk. PMID:22933893

    This paper presents the morpho-sedimentary characterization and interpretations of the assemblage of landforms of the East Greenland continental slope and Greenland Basin, based on swath bathymetry and sub-bottom TOPAS profiles. The interpretation of landforms reveals the glacial influence on recent sedimentary processes shaping the seafloor, including mass-wasting and turbidite flows. The timing of landform development points to a predominantly glacial origin of the sediment supplied to the continental margin, supporting the scenario of a Greenland Ice Sheet extending across the continental shelf, or even to the shelf-edge, during the Last Glacial Maximum (LGM). Major sedimentary processes along the central section of the eastern Greenland Continental Slope, the Norske margin, suggest a relatively high glacial sediment input during the LGM that, probably triggered by tectonic activity, led to the development of scarps and channels on the slope and debris flows on the continental rise. The more southerly Kejser Franz Josef margin has small-scale mass-wasting deposits and an extensive turbidite system that developed in relation to both channelised and unconfined turbidity flows which transferred sediments into the deep Greenland Basin.

    Winter outflows of Arctic sea ice into the Barents Sea are estimated using a 10-year record of satellite ice motion and thickness. The mean winter volume export through the Svalbard/Franz Josef Land passage is 40 km3, and ranges from -280 km3 to 340 km3. A large outflow in 2003 is preconditioned by an unusually high concentration of thick perennial ice over the Nansen Basin at the end of the 2002 summer. With a deep atmospheric low situated over the eastern Barents Sea in winter, the result is an increased export of Arctic ice. The Oct-Mar ice area flux, at 110 x 10 to the third power km3, is not only unusual in magnitude but also remarkable in that >70% of the area is multiyear ice; the ice volume flux at340 km3 is almost one-fifth of the ice flux through the Fram Strait. Another large outflow of Arctic sea ice through this passage, comparable to that in 2003, is found in 1996. This southward flux of sea ice represents one of two major sources of freshwater in the Barents Sea; the other is the eastward flux of water via the Norwegian Coastal Current. The possible consequences of variable freshwater input on the Barents Sea hydrography and its impact on transformation of Atlantic Water en route to the Arctic Ocean are examined with a 25-year coupled ice-ocean model.

  4. Evidence for the role of organics in aerosol particle formation under atmospheric conditions

    New particle formation in the atmosphere is an important parameter in governing the radiative forcing of atmospheric aerosols. However, detailed nucleation mechanisms remain still ambiguous, as laboratory data have so far not been successful in explaining atmospheric nucleation. We investigated the formation of new particles in a smog chamber simulating the photochemical formation of H2SO4 and organic condensable species. Nucleation occurs at H2SO4 concentrations similar to the ones found in the ambient atmosphere during nucleation events. The measured particle formation rates are proportional to the product of the concentrations of H2SO4 and an organic molecule. This suggests that only one H2SO4 molecule and one organic molecule are involved in the rate limiting step of the observed nucleation process. Parameterizing this process in a global aerosol model results in substantially better agreement with ambient observations compared to control runs.

    In the 1990s, an uncommonly high percentage of glutathione S-transferase M1 (GSTM1) negative bladder cancer cases (70%) was reported in the greater Dortmund area. The question arose as to whether this uncommonly high percentage of GSTM1 negative bladder cancer cases was due to environmental and/or occupational exposure decades ago. Thus, 15 years later, another study on bladder cancer was performed in the same area after the coal, iron, and steel industries had finally closed in the 1990s. In total 196 bladder cancer patients from the St.-Josefs-Hospital Dortmund-Hörde and 235 controls with benign urological diseases were assessed by questionnaire and genotyped for GSTM1, glutathione S-transferase T1 (GSTT1), and the N-acetyltransferase 2 (NAT2) tag SNP rs1495741. The frequency of the GSTM1 negative genotype was 52% in bladder cancer cases and thus lower compared to a previous study performed from 1992 to 1995 in the same area (70%). NAT2 genotypes were distributed equally among cases and controls (63% slow acetylators). Fewer GSTT1 negative genotypes were present in cases (17%) than in controls (20%). PMID:22686316

    Interpretation of geophysical data shows that the geological structure of the Eastern Barents Shelf, named Barents Megatrough (BM), extends sublongitudinally almost from the Baltic shield to the Franz Josef Land archipelago. The earth crust within the axis part of the BM is attenuated up to 28-30 km, whereas in adjacent areas its thickness exceeds 35 km. The depression is filled with of more than 15 km of Upper Paleozoic, Mesozoic, and Cenozoic sediments overlying a folded basement of probable Caledonian age. Paleozoic sediments, with exception of the Upper Permian, are composed mainly of carbonates and evaporites. Mesozoic-Cenozoic sediments are mostly terrigenous. The major force in the development of the BM was due to extensional tectonics. Three rifting phases are recognizable: Late Devonian-Early Carboniferous, Early Triassic, and Jurassic-Early Cretaceous. The principal features of the geologic structure and evolution of the BM during the late Paleozoic-Mesozoic correlate well with those of the Sverdup basin, Canadian Arctic. Significant quantity of Late Jurassic-Early Cretaceous basaltic dikes and sills were intruded within Triassic sequence during the third rifting phase. This was probably the main reason for trap disruption and hydrocarbon loss from Triassic structures. Lower Jurassic and Lower Cretaceous reservoir sandstones are most probably the main future objects for oil and gas discoveries within the BM. Upper Jurassic black shales are probably the main source rocks of the BM basin, as well as excellent structural traps for hydrocarbon fluids from the underlying sediments.

    In July of 1931, on the eve of International Polar Year II, an Arctic flight of the Graf Zeppelin rigid airship was organized. This flight was a realization of the idea of F. Nansen, who advocated the use of airships for the scientific exploration of the Arctic territories, which were poorly studied and hardly accessible at that time. The route of the airship flight was Berlin - Leningrad - Arkhangelsk - Franz Josef Land - Severnaya Zemlya - the Taimyr Peninsula - Novaya Zemlya - Arkhangelsk - Berlin. One of scientific goals of the expedition was to measure the H and D geomagnetic field components. Actually, the first aeromagnetic survey was carried out in the Arctic during the flight. After the expedition, only preliminary results of the geomagnetic measurements, in which an anomalous behavior of magnetic declination in the high-latitude part of the route was noted, were published. Our paper is concerned with the first aeromagnetic measurements in the Arctic and their analysis based on archival and modern data on the magnetic field in the Barents and Kara sea regions. It is shown that the magnetic field along the flight route had a complicated structure, which was not reflected in the magnetic charts of those times. The flight was very important for future development of aero- and ground-based magnetic surveys in the Arctic, showing new methods in such surveys.

  8. The cryptomnesic origins of Jung's dream of the multi-storeyed house.

    2009-09-01

    Jung first recounted his dream of the multi-storeyed house in the 1925 seminars to illustrate the concept of the collective unconscious and explain the influence of phylogeny on his split with Freud. However, his telling the story of the dream belies a cryptomnesic influence of the early writings of psychoanalysis because Josef Breuer used a similar image to illustrate the structure of the psyche which Edouard Claparède associated with a phylogenetic inheritance. When telling the story of the dream, Jung misrepresented Freud's position, creating the impression of there being a bigger difference between their theories than was actually the case, and giving the dream a fictional significance for the breakdown of their relationship. In fact, Jung followed Freud into the fields of mythology and phylogenetics, and their split was due primarily to their different attitudes towards sexuality rather than phylogeny. The dream image has therefore led to a misunderstanding of Freudian theory when viewed from within a Jungian perspective. Freud believed there was a phylogenetic layer in the psyche, though he held a different view to Jung on its nature and importance. PMID:19765139

    This article will explore the representation of certain mental and somatic phenomena in Beckett's trilogy of novels Molloy, Malone Dies and The Unnamable, exploring how his understanding of schizophrenia and psychosis informs his representation of the relationship between mind and body. It will also examine recent phenomenological and philosophical accounts of schizophrenia (Louis Sass, Josef Parnas, Shaun Gallagher) that see the condition as a disorder of selfhood and concentrate in it on the disruption to ipseity, a fundamental and pre-reflective awareness of self that leads to a loss of 'grip' (in the term of Merleau-Ponty) on concepts and percepts. Beckett's writing might, it is argued, make such disruptions more tangible and intelligible. The article will also consider John Campbell's argument that immunity of the first person to error-Sydney Shoemaker's foundational philosophical idea that we cannot misspeak the first person pronoun-is revoked in states of psychosis, and relate such states to the moments in Beckett's writing where this immunity is challenged, and quasi-psychotic experiences represented.

  10. The Contribution of Ernst Mach to Embodied Cognition and Mathematics Education

    A study of the interactions between mathematics and cognitive science, carried out within a historical perspective, is important for a better understanding of mathematics education in the present. This is evident when analysing the contribution made by the epistemological theories of Ernst Mach. On the basis of such theories, a didactic method was developed, which was used in the teaching of mathematics in Austria at the beginning of the twentieth century and applied to different subjects ranging from simple operations in arithmetic to calculus. Besides the relevance of this method—also named the "Jacob method" after Josef Jacob who proposed it—to teaching practice, it could also be considered interesting in a wider context with reference to the mind-body problem. In particular, the importance that Jacob gives to "muscular activity" in the process of forming and elaborating mathematical concepts, derived from Mach, resounds in the current debate on embodied cognition, where cognitive processes are understood not as expressions of an abstract and merely computational mind but as based on our physicality as human beings, equipped not just with a brain but also a (whole) body. This model has been applied to mathematics in the "theory of embodied mathematics", the objective of which is to study, with the methods and apparatus of embodied cognitive science, the cognitive mechanisms used in the human creation and conceptualisation of mathematics. The present article shows that the "Jacob method" may be considered a historical example of didactical application of analogous ideas.

    We use a combination of ASTER and cartographically derived Digital Elevation Models (DEMs) supplemented with WorldView DEMs, the ArcticDEM and ICESat lidar returns to produce a time-series of ice changes occurring in the Russian High Arctic between the mid-20th century and the present. Glaciers on the western, Barents Sea coast of Novaya Zemlya are in a state of general retreat and thinning, while those on the eastern, Kara Sea coast are retreating at a slower rate. Franz Josef Land has a complicated pattern of thinning and thickening, although almost all the thinning is associated with rapid outlet glaciers feeding ice shelves. Severnaya Zemlya is also thinning in a complicated manner. A very rapid surging glacier is transferring mass into the ocean from the western periphery of the Vavilov Ice Cap on October Revolution Island, while glaciers feeding the former Matusevich Ice Shelf continue to thin at rates that are faster than those observed during the operational period of ICESat, between 2003 and 2009. Passive microwave studies indicate the total number of melt days is increasing in the Russian Arctic, although much of the melt may refreeze within the firn. It is likely that ice dynamic changes will drive mass loss for the immediate future. The sub-marine basins beneath several of the ice caps in the region suggest the possibility that mass loss rates may accelerate in the future.

    In 1943 the US Army established the Special Engineering Detachment (SED), in which mostly drafted young soldiers possessing some scientific credentials (though usually quite minimal) were reassigned from other duties to the Manhattan Project to assist in various research and development aspects of nuclear weapons. The Los Alamos contingent, never more than a few hundred GIs, worked with more senior scientists and engineers, often assuming positions of real responsibility. An unintended consequence of this circumstance was the fact that being in the SEDs turned out to be a fortuitous breeding ground for future physicists, chemists, and engineers. SEDs benefited from their close contacts with established scientists, working with them side by side, attended lectures by luminaries, and gained invaluable experience that would help them establish academic and industrial careers later in life. I will discuss some of these individuals (I list only those of whom I am personally aware).

    Analysis of optical satellite imagery (ASTER) has revealed the contrasting response of mountain glaciers to similar climatic forcing. High-resolution and near-complete coverage of ice velocities in the central part of the Southern Alps, New Zealand, has been obtained from feature tracking using repeat imagery in 2002 and 2006. Precise orthorectification, co-registration and correlation is carried out using the freely available software COSI-corr. This analysis, combined with short time windows, has enabled velocities to be captured even in the accumulation areas, where velocities are lowest and surface features ephemeral. The results indicate large dynamic changes in some glaciers have occurred between 2002 and 2006. The steep and more responsive Fox and Franz Josef Glaciers increased speed by factors of as much as three during the period, while the low-angled and debris covered Tasman Glacier showed no measurable velocity change. Velocity increases on the steeper glaciers are the result of an observed thickening and steepening of the glacier tongues as the glaciers moved from a retreat phase in 2002 to an advance phase in 2006. This contrasting behaviour is consistent with observed terminus position changes - the steeper glaciers have undergone several advance/retreat cycles during the period of observation (1894 - present) while the low-angled glacier showed little terminus response until retreat resulting from the accelerating growth of a pro-glacial lake in 1983.

    The standard neurologic examination of the newborn and infant includes the elicitation of the tonic neck reflex. Normally present, its persistence is suggestive of neurologic dysfunction and a prognostic marker highly suggestive of an adverse outcome. Working in different fields, with different approaches and largely independently, three leaders of early 20th century neurosciences (Rudolf Magnus, Josef Gerstmann, and Arnold Gesell) elaborated different aspects of this primitive reflex. Magnus provided the first description in an animal model utilizing a meticulously prepared decerebrate cat correctly identifying the reflex's reliance on proprioceptors in the neck and processing in the upper cervical segment. Gerstmann first described its occurrence in the setting of neurologic disease, providing a meticulous written description in an early description of the index case of what would later be eponymously designated Gerstmann-Straussler-Scheinker syndrome. Gesell initially described the reflex's fundamental occurrence in normal young infants, highlighting its adaptive role in early development and its persistence as a hallmark of neurologic pathology.

Some of his teachers belonged to the famous second "Vienna School" such as Joseph Skoda, Karl Rokitansky, Von Hebra, Josef Hyrtil, Johann Von Oppolzer and famous physiologist Carl Ludwig -who took special interest in him and was influential in his subsequent career. Politzer showed unusual interest in diseases of the ear and started to work in Carl Ludwig's laboratory. His interest at that time was mainly the physics of the auditory system. He studied the innervations of the intrinsic muscles of the ear There he was the first to demonstrate that the innervations of the tensor tympani muscle was by trigeminal nerve and that of the stapedial muscle was by facial nerve. He studied the air movement in the Eustachian tube and variation of air pressure in the tympanic cavity by connecting two manometers- one placed in the external auditory canal meatus, and another in the pharynx. He showed valve near the opening into the middle ear which controls the process. It is usually closed to keep the bacteria and other things away from the mouth and nose. PMID:27608882

    The 1939 Nobel Laureate in Chemistry and later President of the Max Planck Society Adolf Butenandt has been increasingly exposed to criticism in recent years. One far-reaching accusation against him is his postulated participation in the human experiments executed by the SS-physician Josef Mengele in the Auschwitz concentration camp. It concerns a project initiated by anthropologist Otmar von Verschuer in 1943. For this, Verschu-ER Obtained blood samples from his assistant Mengele in the Auschwitz concentration camp. When methodological problems occurred in the project Butenandt helped Verschuer. According to the reconstruction of geneticist Benno Müller-Hill the research project included lethal human experiments: Mengele had selectively infected concentration camp detainees with tuberculosis to observe their racially conditioned resistibility against that disease, he claims. This reconstruction, however, contradicts other sources. Therefore an alternative reconstruction is offered here. According to that, the project represented a large-scale attempt of serological race diagnosis in man. Human experiments are not plausible for this project. Yet it is clearly connected to race biological research and implementation. PMID:18447187

The present paper, based mostly on recently discovered archival data reconstructs his biography and corrects some mistakes of the previous biographical works. Veza's curriculum vitae shortly sounds as follows: Born in Vienna, in 1728 in an Austrian, Catholic family. His father had been Josef Veza, an agent of the Habsburg emperor in the Low Countries. Gábor Veza graduated in Toscana in Pisa (1751) later practised medicine in military hospitals, practising privately too. During this period he moved to Buda. He repeated his graduation at the University of Vienna as well (1757) and stood in military service for 25 years (till 1787) as a leading surgeon of the Garrison at Buda. At the same time he worked as a medical officer of County Pest. In 1777 he was appointed to director of medical faculty of the Royal Hungarian University, in 1787 to Royal Counsellor, in 1787 to Protomedicus of Hungary. PMID:12814115

    Throughout his medical career, Robert Dunn (1799-1877) published a number of clinical cases with postmortem reports involving acquired language disorders, with the first noted in 1842. He developed a physiologically informed approach to psychological function during the 1850s along with a group of notable colleagues Benjamin Collins Brodie, Henry Holland, Thomas Laycock, John Daniel Morell, and Daniel Noble. He was also active in ethnographic research on human origins and racial diversity. As such, Dunn represents an interesting player in the developing fields of neurology, psychology, and anthropology in England in the latter part of the nineteenth century. These various strands converged at the meeting of the British Association of the Advancement of Science in 1868, where Dunn shared the program of lectures on the cutting-edge topic of aphasia with Paul Broca (1824-1880) and John Hughlings Jackson (1835-1911). Dunn's ideas developed over a longer time frame than his younger colleagues and as such represent a unique blending of concepts from the earlier work of Franz Josef Gall (1758-1828) and Jean-Baptiste Bouillaud (1798-1881) to the perspectives on language organization in the brain developed after 1861.
