  4. Surface slip during large Owens Valley earthquakes

    KAUST Repository

    Haddon, E. K.

    2016-01-10

    The 1872 Owens Valley earthquake is the third largest known historical earthquake in California. Relatively sparse field data and a complex rupture trace, however, inhibited attempts to fully resolve the slip distribution and reconcile the total moment release. We present a new, comprehensive record of surface slip based on lidar and field investigation, documenting 162 new measurements of laterally and vertically displaced landforms for 1872 and prehistoric Owens Valley earthquakes. Our lidar analysis uses a newly developed analytical tool to measure fault slip based on cross-correlation of sublinear topographic features and to produce a uniquely shaped probability density function (PDF) for each measurement. Stacking PDFs along strike to form cumulative offset probability distribution plots (COPDs) highlights common values corresponding to single and multiple-event displacements. Lateral offsets for 1872 vary systematically from approximate to 1.0 to 6.0 m and average 3.31.1 m (2 sigma). Vertical offsets are predominantly east-down between approximate to 0.1 and 2.4 m, with a mean of 0.80.5 m. The average lateral-to-vertical ratio compiled at specific sites is approximate to 6:1. Summing displacements across subparallel, overlapping rupture traces implies a maximum of 7-11 m and net average of 4.41.5 m, corresponding to a geologic M-w approximate to 7.5 for the 1872 event. We attribute progressively higher-offset lateral COPD peaks at 7.12.0 m, 12.8 +/- 1.5 m, and 16.6 +/- 1.4 m to three earlier large surface ruptures. Evaluating cumulative displacements in context with previously dated landforms in Owens Valley suggests relatively modest rates of fault slip, averaging between approximate to 0.6 and 1.6 mm/yr (1 sigma) over the late Quaternary.

    2010-05-01

    Isambard Owen, born in Chepstow to a Welsh father, studied at Cambridge and St George's Hospital where he qualified in 1875 and was later physician and Dean. In 1904 he moved to Newcastle-upon-Tyne as Principal of Armstrong College. He left in 1909 to become Bristol University's Vice-Chancellor, retiring in 1921. Although not resident in Wales he was an ardent Welshman. After joining the Cymmrodorion Society in 1877 he became involved in the struggle to improve primary and secondary education in Wales, partly by promoting use of the Welsh language in schools. His main contribution to Welsh academic life was in the foundation of the University of Wales and, later, of the medical school in Cardiff. He wrote the University's Charter and from 1895 until 1910 was its Senior Deputy Chancellor - and stand-in for two Princes of Wales (later Edward VII and George V) who served as Chancellor.

  7. The fossil mammals collected byCharles Darwin in South America during his travels on board the HMS Beagle

    Full Text Available Duringthe first two years of his voyage aboard HMS Beagle, Charles Darwin collected aconsiderable number of fossil mammals from various localities in Argentina andUruguay. Among these remains are those of large mammals that Darwin informallyassigned to Megatherium and Mastodon, the only large taxa thenknown for South America, and of small and mediumsized mammals that Darwinrecognized as representing at least two rodents and a horse. The study ofDarwin's collection was entrusted to Richard Owen, who described eleven taxabetween 1837 and 1845, including the six following ones: Toxodon platensis,Macrauchenia patachonica, Equus curvidens, Scelidotherium leptocephalum,Mylodon darwini and Glossotherium sp. This contribution provides asynthesis of Darwin's preliminary assignments and evaluates the reasons thatled him to recognize only megatheres and mastodonts for the large fossilremains. Also, it discusses the current taxonomic status of the taxa describedor erected by Owen between 1837 and 1845 and the influence that Owen'staxonomic and phylogenetic conclusions had on the development of Darwin's ideason evolution.

  8. Late Quaternary MIS 6-8 shoreline features of pluvial Owens Lake, Owens Valley, eastern California

    2008-01-01

    The chronologic history of pluvial Owens Lake along the eastern Sierra Nevada in Owens Valley, California, has previously been reported for the interval of time from ca. 25 calibrated ka to the present. However, the age, distribution, and paleoclimatic context of higher-elevation shoreline features have not been formally documented. We describe the location and characteristics of wave-formed erosional and depositional features, as well as fluvial strath terraces that grade into an older shoreline of pluvial Owens Lake. These pluvial-lacustrine features are described between the Olancha area to the south and Poverty Hills area to the north, and they appear to be vertically deformed -20 ?? 4 m across the active oblique-dextral Owens Valley fault zone. They occur at elevations from 1176 to 1182 m along the lower flanks of the Inyo Mountains and Coso Range east of the fault zone to as high as -1204 m west of the fault zone. This relict shoreline, referred to as the 1180 m shoreline, lies -20-40 m higher than the previously documented Last Glacial Maximum shoreline at -1160 m, which occupied the valley during marine isotope stage 2 (MIS 2). Crosscutting relations of wave-formed platforms, notches, and sandy beach deposits, as well as strath terraces on lava flows of the Big Pine volcanic field, bracket the age of the 1180 m shoreline to the time interval between ca. 340 ?? 60 ka and ca. 130 ?? 50 ka. This interval includes marine oxygen isotope stages 8-6 (MIS 8-6), corresponding to 260-240 ka and 185-130 ka, respectively. An additional age estimate for this shoreline is provided by a cosmogenic 36Cl model age of ca. 160 ?? 32 ka on reefal tufa at ???1170 m elevation from the southeastern margin of the valley. This 36Cl model age corroborates the constraining ages based on dated lava flows and refines the lake age to the MIS 6 interval. Documentation of this larger pluvial Owens Lake offers insight to the hydrologic balance along the east side of the southern Sierra

  9. Owen Martin Phillips (1930-2010)

    2011-02-01

    Owen Martin Phillips, a pioneer in geophysical fluid dynamics, died at home on 13 October 2010 in Chestertown, Md., at the age of 79. To his many friends and colleagues, Phillips was an inspirational and gracious person who combined a deep intellect, a lively spirit, and a generous heart that matched his passionate interest in the geophysical sciences. Phillips was born on 30 December 1930 in Parramatta, N. S. W., Australia. In 1948 he enrolled in the University of Sydney, where he earned a B.S. in applied mathematics in 1952. That same year, he joined the Cavendish Laboratory at Cambridge University as a research student, where he began to apply to the ocean concepts in turbulent flow recently developed by Andrei Kolmogorov, G. I. Taylor, and George Batchelor. While attending the 1956 celebration of Taylor's seventieth birthday, Phillips heard Fritz Ursell declare that “the process by which ocean waves are generated by the wind cannot be regarded as known.” In 1957 the Journal of Fluid Mechanics contained two remarkable papers offering contrasting theories for ocean wave generation. One paper, by the applied mathematician John Miles (J. Fluid Mech., 2(5), 417-445, 1957), proposed that energy transfer from the air to the sea occurs at a critical layer in the atmosphere boundary layer. The other paper, by Phillips, then 26 years old (J. Fluid Mech., 3(2), 185-204, 1957), proposed that turbulent pressure fluctuations in the wind resonate with propagating ocean waves, forcing them to grow. Together these became known as the Phillips-Miles process, and it was the opening salvo in Phillips's 50-year career of innovative contributions to geophysics through fluid mechanics.

  10. Long Valley Caldera Lake and reincision of Owens River Gorge

    Science.gov (United States)

    Hildreth, Wes; Fierstein, Judy

    2016-12-16

    Owens River Gorge, today rimmed exclusively in 767-ka Bishop Tuff, was first cut during the Neogene through a ridge of Triassic granodiorite to a depth as great as its present-day floor and was then filled to its rim by a small basaltic shield at 3.3 Ma. The gorge-filling basalt, 200 m thick, blocked a 5-km-long reach of the upper gorge, diverting the Owens River southward around the shield into Rock Creek where another 200-m-deep gorge was cut through the same basement ridge. Much later, during Marine Isotope Stage (MIS) 22 (~900–866 ka), a piedmont glacier buried the diversion and deposited a thick sheet of Sherwin Till atop the basalt on both sides of the original gorge, showing that the basalt-filled reach had not, by then, been reexcavated. At 767 ka, eruption of the Bishop Tuff blanketed the landscape with welded ignimbrite, deeply covering the till, basalt, and granodiorite and completely filling all additional reaches of both Rock Creek canyon and Owens River Gorge. The ignimbrite rests directly on the basalt and till along the walls of Owens Gorge, but nowhere was it inset against either, showing that the basalt-blocked reach had still not been reexcavated. Subsidence of Long Valley Caldera at 767 ka produced a steep-walled depression at least 700 m deeper than the precaldera floor of Owens Gorge, which was beheaded at the caldera’s southeast rim. Caldera collapse reoriented proximal drainages that had formerly joined east-flowing Owens River, abruptly reversing flow westward into the caldera. It took 600,000 years of sedimentation in the 26-km-long, usually shallow, caldera lake to fill the deep basin and raise lake level to its threshold for overflow. Not until then did reestablishment of Owens River Gorge begin, by incision of the gorge-filling ignimbrite.

  13. Preliminary evaluation of the hydrogeologic system in Owens Valley, California

    Danskin, W.R.

    1988-01-01

    A preliminary, two-layer, steady-state, groundwater flow model was used to evaluate present data and hydrologic concepts of Owens Valley, California. Simulations of the groundwater system indicate that areas where water levels are most affected by changes in recharge and discharge are near toes of alluvial fans and along the edge of permeable volcanic deposits. Sensitivity analysis for each model parameter shows that steady state simulations are most sensitive to uncertainties in evapotranspiration rates. Tungsten Hills, Poverty Hills, and Alabama Hills were found to act as virtually impermeable barriers to groundwater flow. Accurate simulation of the groundwater system between Bishop and Lone Pine appears to be possible without simulating the groundwater system in Round Valley, near Owens Lake, or in aquifer materials more than 1,000 ft below land surface. Although vast amounts of geologic and hydrologic data have been collected for Owens Valley, many parts of the hydrogeologic system have not been defined with sufficient detail to answer present water management questions. Location and extent of geologic materials that impede the vertical movement of water are poorly documented. The likely range of aquifer characteristics, except vertical hydraulic conductivity, is well known, but spatial distribution of these characteristics is not well documented. A set of consistent water budgets is needed, including one for surface water, groundwater, and the entire valley. The largest component of previous water budgets (evapotranspiration) is largely unverified. More definitive estimates of local gains and losses for Owens River are needed. Although groundwater pumpage from each well is measured, the quantity of withdrawal from different zones of permeable material has not been defined. (USGS)

  14. Craddock & Owen vs Kraepelin: 85 years late, mesmerised by "polygenes".

    Science.gov (United States)

    Crow, T J

    2008-08-01

    The case for replacing the binary Kraepelinian system with a continuum concept originated with Kraepelin [Kraepelin, E. (1920) Die Erscheinungsformen des Irreseins (translated by H Marshall as: Patterns of mental disorder. In: Themes and Variations in European Psychiatry. Eds S.R. Hirsch & M. Shepherd. Wright, Bristol, pp7-30, l974). Zeitschrift Gesamte Neurologie Psychiatrie, vol. 62, 1-29.], and is based upon studies of familial aggregation and phenomenology. Craddock and Owen's [Craddock, N.J., Owen, M.J. (2007) Rethinking psychosis: the disadvantages of a dichotomous classification now outweigh the advantages. World Psychiatry 6: 20-27.] claim for the "beginning of the end for the Kraepelinian dichotomy" on the basis of linkage and association is undermined by un-replicability of findings across studies (Crow, T.J. (2007) How and why genetic linkage has not solved the problem of psychosis: review and hypothesis. American Journal of Psychiatry, 164, 13-21). Absence of evidence of linkage is consistent with the concept that the variation is epigenetic in form rather than DNA sequence-based. But what are the dimensions that underly the continuum? The BBC Internet survey (Peters, M., Reimers, S., Manning, J.T. (2006) Hand preference for writing and associations with selected demographic and behavioral variables in 255,100 subjects: the BBC internet study. Brain and Cognition 62, 177-189), reinforces the concept that lateralisation is a major and sex-dependent dimension of human variation in verbal and spatial ability: twin studies indicate that inter-individual variation in dominance for language is epigenetic and the paternal age effect can be similarly explained. Thus an epigenetic imprint, arising in relation to the sapiens specific torque and persisting over one or two generations is a better fit to the genetics of the psychotic continuum than Craddock and Owen's elusive "polygenic" variations.

    1991-01-01

    Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports the water more than 200 miles south to areas of distribution and use. Additionally, ground water is pumped or flows from wells to supplement the surface-water diversions to the river-aqueduct system. Pumpage from wells needed to supplement water export has increased since 1970, when a second aqueduct was put into service, and local concerns have been expressed that the increased pumpage may have had a detrimental effect on the environment and the indigenous alkaline scrub and meadow plant communities in the valley. The scrub and meadow communities depend on soil moisture derived from precipitation and the unconfined part of a multilayered aquifer system. This report, which describes the hydrogeology of the aquifer system and the water resources of the valley, is one in a series designed to (1) evaluate the effects that groundwater pumping has on scrub and meadow communities and (2) appraise alternative strategies to mitigate any adverse effects caused by, pumping. Two principal topographic features are the surface expression of the geologic framework--the high, prominent mountains on the east and west sides of the valley and the long, narrow intermountain valley floor. The mountains are composed of sedimentary, granitic, and metamorphic rocks, mantled in part by volcanic rocks as well as by glacial, talus, and fluvial deposits. The valley floor is underlain by valley fill that consists of unconsolidated to moderately consolidated alluvial fan, transition-zone, glacial and talus, and fluvial and lacustrine deposits. The valley fill also includes interlayered recent volcanic flows and pyroclastic rocks. The bedrock surface beneath the valley fill is a narrow, steep-sided graben

    2014-05-01

    The complexity of the Matuyama/Brunhes (M/B) polarity transition is becoming better understood from investigations of volcanic rocks (Coe et al., 2004), loess (Jin et al., 2012; Evans et al., 2011; Kravchinsky, 2013), and marine (Clement and Opdyke, 1982; Hartl and Tauxe, 1996; Macri et al., 2010) and lacustrine (Valet et al., 1988; Sagnotti et al., 2013) sediments. The transition appears to include a brief interval of normal polarity prior to the entry into the Brunhes Normal Chron (Coe et al., 2004; Jin et al., 2012; Evans et al., 2011), and the transition has Virtual Geomagnetic Poles rapidly moving from the Southern Hemisphere to the Northern Hemisphere (Coe et al., 2004; Jin et al., 2012; Evans et al., 2011; Sagnotti et al., 2013). The M/B polarity transition is recorded in exposed Pleistocene lake sediments near Bishop, CA, where the brief interval of normal polarity noted above is present and the change from full reverse to full normal polarity occurs rapidly. The brief interval of normal polarity is recorded at two sites separated laterally by about 150 m and is in single hand samples measured at vertical spacing of 2.0-2.5 cm using six samples per measured level and alternating field demagnetization at 20 mT (Liddicoat, 1993, Table 1 and Fig. 8). The siltstone is unweathered glacial flour from the Sierra Nevada that borders the western side of Owens Valley where the sediments were deposited in Owens Lake. In the siltstone, the majority of the samples have a percentage of about 60 percent where the grain diameter is less than 63 micrometres, and in those samples there is about a five percent fraction when the diameter is two micrometres or less. The Total Inorganic Carbon in most samples is about 0.25 percent (Bergeron, 2013), and magnetite is the dominant carrier of the magnetization (Liddicoat, 1993). The palaeomagnetic directions recording the terminus of the full M/B transition, which occurs before the field intensity is completely recovered, spans no

    The Expanded Owens Valley Solar Array (EOVSA) is a solar-dedicated radio array that makes images and spectra of the full Sun on a daily basis. Our main science goals are to understand the basic physics of solar activity, such as how the Sun releases stored magnetic energy on timescales of seconds, and how that solar activity, in the form of solar flares and coronal mass ejections, influences the Earth and near-Earth space environment, through disruptions of communication and navigation systems, and effects on satellites and systems on the ground. The array, which is composed out of thirteen 2.1 m dishes and two 27 m dishes (used only for calibration), has a footprint of 1.1 km EW x 1.2 km NS and it is capable of producing, every second, microwave images at two polarizations and 500 science channels spanning the 1-18 GHz frequency range. Such ability to make multi-frequency images of the Sun in this broad range of frequencies, with a frequency dependent resolution ranging from ˜53” at 1 GHz to ˜3”at 18 GHz, is unique in the world. Here we present an overview of the EOVSA instrument and a first set of science-quality active region and solar flare images produced from data taken during April 2017.This research is supported by NSF grant AST-1615807 and NASA grant NNX14AK66G to New Jersey Institute of Technology.

    Full Text Available This paper focuses on Owen Sound's relation between the port and the settlement, and how the port played a major role in a town rising to the city status. Owen Sound history is, though important for Canadian history may be, an adequate case study of the role of ports in generating communities as well as of the preeminence of the human factor over the much emphasized locational analysis.

    Este artículo se centra en la relación existente entre el puerto y el asentamiento, así cómo el papel central que el puerto jugó en la conversión del pueblo en una ciudad. A pesar de la importancia que dicha ciudad tiene en la historia canadiense, Owen Sound es un buen caso de estudio para evaluar el papel de los puertos en la génesis de comunidades así como de la preeminencia del factor humano sobre los excesivamente valorados análisis locacionales.

  8. Dust Generation Resulting from Desiccation of Playa Systems: Studies on Mono and Owens Lakes, California

    Science.gov (United States)

    Gill, Thomas Edward

    1995-01-01

    Playas, evaporites, and aeolian sediments frequently are linked components within the Earth system. Anthropogenic water diversions from terminal lakes form playas that release fugitive dust. These actions, documented worldwide, simulate aeolian processes activated during palaeoclimatic pluvial/interpluvial transitions, and have significant environmental impacts. Pluvial lakes Russell and Owens in North America's Great Basin preceded historic Mono and Owens Lakes, now desiccated by water diversions into dust-generating, evaporite -encrusted playas. Geochemical and hydrologic cycles acting on the Owens (Dry) Lake playa form three distinct crust types each year. Although initial dust production results from deflation of surface efflorescences after the playa dries, most aerosols are created by saltation abrasion of salt/silt/clay crusts at crust/ sand sheet contacts. The warm-season, clastic "cemented" crust is slowest to degrade into dust. If the playa surface is stabilized by an unbroken, non-efflorescent crust, dust formation is discouraged. When Mono Lake's surFace elevation does not exceed 1951 meters (6400 feet), similar processes will also generate dust from its saline lower playa. Six factors--related to wind, topography, groundwater, and sediments--control dust formation at both playas. These factors were combined into a statistical model relating suspended dust concentrations to playa/lake morphometry. The model shows the extent and severity of Mono Lake dust storms expands significantly below the surface level 6376 feet (1943.5 meters). X-ray diffraction analysis of Mono Basin soils, playa sediments, and aerosols demonstrates geochemical cycling of materials through land, air and water during Mono Lake's 1982 low stand. Soils and clastic playa sediments contain silicate minerals and tephra. Saline groundwater deposited calcite, halite, thenardite, gaylussite, burkeite and glauberite onto the lower playa. Aerosols contained silicate minerals (especially

    Full Text Available Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

  10. 21 cm Fluctuations of the Cosmic Dawn with the Owens Valley Long Wavelength Array

    Eastwood, Michael; Hallinan, Gregg; Owens Valley LWA Collaboration

    2016-01-01

    The Owens Valley Long Wavelength Array (OVRO LWA) is a 288-antenna interferometer covering 30 to 80 MHz located at the Owens Valley Radio Observatory (OVRO) near Big Pine, California. I am leading the effort to detect spatial fluctuations of the 21 cm transition from the cosmic dawn (z~20) with the OVRO LWA. These spatial fluctuations are primarily sourced by inhomogeneous X-ray heating from early star formation. The spectral hardness of early X-ray sources, stellar feedback mechanisms, and baryon streaming therefore all play a role in shaping the power spectrum. I will present the application of m-mode analysis (Shaw et al. 2014, Shaw et al. 2015) to OVRO LWA data to: 1. compress the data set, 2. create maps of the northern sky that can be fed back into the calibration pipeline, and 3. filter foreground emission. Finally I will present the current status and future prospects of the OVRO LWA for detecting the 21 cm power spectrum at z~20.

  11. A ‘War Poet’ or A ‘Poet At War’: Wilfred Owen and the Pity of War

    Directory of Open Access Journals (Sweden)

    George Ewane Ngide

    2016-01-01

    Full Text Available This article sets out to examine Wilfred Owen’s war poems which showcase his vigorous philosophy on and against war. We contend that instead of considered only as “a war poet”, Owen was more “a poet at war”, better still, a poet against war. The terms are used in this paper to mean on the one hand that Owen was less a poet who took part in war, and more a poet who wars against war. Put differently, Owen does not just describe what he himself calls “The pity of war” with the gruesome and excruciating experiences of soldiers in combat, but he also uses firsthand experience on the battlefield (having been a soldier himself  to call for an end to war. In the preface to his poems he writes that “The poetry is in the pity”. His descriptions of war experiences are so profound that they discourage any possibility of  war, thus leaving the human race with one option namely, negotiation and peaceful resolution of conflicts by those he calls “better men” who in the future will profoundly be involved in what he calls “greater wars”. Keywords: Owen, war, pity, conflicts, negotiation, philosophy

    2013-01-01

    This paper examines a succession of incidents at a critical juncture in the life of Professor Horace Lamb FRS, a highly regarded classical fluid mechanicist, who, over a period of some 35 years at Manchester, made notable contributions in research, in education and in wise administration at both national and university levels. Drawing on archived documents from the universities of Manchester and Adelaide, the article presents the unusual sequence of events that led to his removing from Adelaide, South Australia, where he had served for nine years as the Elder Professor of Mathematics, to Manchester. In 1885 he was initially appointed to the vacant Chair of Pure Mathematics at Owens College and then, in 1888, as an outcome of his proposal for rearranging professorial responsibilities, to the Beyer Professorship of Pure and Applied Mathematics.

    2009-01-01

    The study of alkaliphilic microbial communities from anaerobic sediments of Owens and Mono Lakes in California led to the isolation of a bacterial strain capable of metabolizing amino acids with alternative chirality. According to the phylogenetic analysis, the anaerobic strain BK1 belongs to the genus Tindallia; however, despite the characteristics of other described species of this genus, the strain BK1 was able to grow on D-arginine and Dlysine. Cell morphology of this strain showed straight, motile, non-spore-forming rods with sizes 0.45 x 1.2-3 microns. Physiological characteristics of the strain showed that it is catalase negative, obligately anaerobic, mesophilic, and obligately alkaliphilic. This isolate is unable to grow at pH 7 and requires CO3 (2-) ions for growth. The strain has chemo-heterotrophic metabolism and is able to ferment various proteolysis products and some sugars. It plays the role of a primary anaerobe within the trophic chain of an anaerobic microbial community by the degradation of complex protein molecules to smaller and less energetic molecules. The new isolate requires NaCl for growth, and can grow within the range of 0.5-13 %, with the optimum at 1 % NaCl (w/v). The temperature range for the growth of the new isolate is 12-40 C with optimum at 35 C. The pH range for the growth of strain BK1 occurs between 7.8 and 11.0 with optimum at 9.5. This paper presents detailed physiological characteristics of the novel isolate from Owens Lake, a unique relic ecosystem of Astrobiological significance, and makes an accent on the ability of this strain to utilize L-amino acids.

  16. Paleontology in parts: Richard Owen, William John Broderip, and the serialization of science in early Victorian Britain.

    Dawson, Gowan

    2012-12-01

    While a great deal of scholarly attention has been given to the publication of serialized novels in early Victorian Britain, there has been hardly any consideration of the no less widespread practice of issuing scientific works in parts and numbers. What scholarship there has been has insisted that scientific part-works operated on entirely different principles from the strategies for maintaining readerly interest that were being developed by serial novelists like Charles Dickens. Deploying the methods of book history, this essay examines the reporting of Richard Owen's celebrated paleontological reconstructions from the 1830s and 1840s in the serialized formats of the Proceedings of the Zoological Society, his own History of British Fossil Mammals, and, in particular, the Penny Cyclopaedia. It argues that Owen, along with his close friend William John Broderip, clearly recognized the affective possibilities of the serial format and that they exploited the Penny Cyclopaedia's sequential mode of publication to evoke suspense and expectation in their anonymous but collaboratively authored accounts of Owen's paleontological researches.

Irrawaddy dolphins (Orcaella brevirostris (Owen in Gray 1866 is one of aquatic mammals species who populations are increasingly threatened. The lack information about population of Irrawaddy dolphins in West Kalimantan waters makes the conservation of this species and its management were still not optimized yet. This research aims to identify the characteristics and behavior of dolphins found in Kubu Raya and Kayong Utara waters of West Kalimantan. The observation was held on April 2013, exploring coastal waters and estuaries which are expected to be the habitats of Irrawaddy dolphins using binoculars. There are 4-6 individuals of Irrawaddy dolphin found at the mouth of Bumbun River. A group consist of young and adults dolphins at the depth of 11 meters. The observed behavior is chasing schooling fish and occasionally spitting water from his blowhole. Based on morphological character and fish behavior observed, and environmental condition parameters, indicated that the water surrounding of Kubu Raya and Kayong Utara District were potential habitat for Irrawaddy dolphins.

  18. Glacial-interglacial climate changes recorded by debris flow fan deposits, Owens Valley, California

    D'Arcy, Mitch; Roda-Boluda, Duna C.; Whittaker, Alexander C.

    2017-08-01

    It is hotly debated whether and how climate changes are recorded by terrestrial stratigraphy. Basin sediments produced by catchment-alluvial fan systems may record past climate over a variety of timescales, and could offer unique information about how climate controls sedimentation. Unfortunately, there are fundamental uncertainties about how climatic variables such as rainfall and temperature translate into sedimentological signals. Here, we examine 35 debris flow fan surfaces in Owens Valley, California, that record deposition throughout the past 125,000 years, during which climate has varied significantly. We show that the last full glacial-interglacial cycle is recorded with high fidelity by the grain size distributions of the debris flow deposits. These flows transported finer sediment during the cooler glacial climate, and became systematically coarser-grained as the climate warmed and dried. We explore the physical mechanisms that might explain this signal, and rule out changes in sediment supply through time. Instead, we propose that grain size records past changes in storm intensity, which is responsible for debris flow initiation in this area and is decoupled from average rainfall rates. This is supported by an exponential Clausius-Clapeyron-style scaling between grain size and temperature, and also reconciles with climate dynamics and the initiation of debris flows. The fact that these alluvial fans exhibit a strong, sustained sensitivity to orbital climate changes sheds new light on how eroding landscapes and their sedimentary products respond to climatic forcing. Finally, our findings highlight the importance of threshold-controlled events, such as storms and debris flows, in driving erosion and sedimentation at the Earth's surface in response to climate change.

  19. ‘By a Comparison of Incidents and Dialogue’: Richard Owen, Comparative Anatomy and Victorian Serial Fiction

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Darwin’s extensive reading of literature was a crucial starting point for Gillian Beer’s insights into the interchange between science and culture which have shaped scholarship in the field for the last three decades. However, while the impact of Darwin’s reading on the imaginative development of his theories has continued to be an extremely productive area of study, there has been hardly any consideration of the broader context of nineteenth-century scientists’ reading practices in relation to literature, giving the impression that Darwin’s thought was especially, perhaps uniquely, amenable to the impact of his immersion in fiction and poetry. This paper examines the extensive but relatively little-known literary reading of the comparative anatomist Richard Owen, suggesting that important aspects of other, and even explicitly non-Darwinian, areas of Victorian science were just as likely to be influenced by their practitioners’ enthusiasm for fiction and poetry. That Darwin and Owen frequently read the same literary works, and often in the same or similar locations (whether in metropolitan clubs or out in the field, also permits direct comparisons of their reading practices, which, intriguingly, suggest that, far from being uniquely amenable to it, Darwin’s scientific thought might in fact have been shaped much less by his literary reading than that of contemporaneous naturalists like Owen. In particular, the paper focuses on Owen’s reading of serial fiction, and considers the close parallels between his practices of reading serial novels and his use of comparative anatomy in his renowned reconstructions of the skeletons of prehistoric creatures.

  20. Long-term weathering effects on the thermal performance of the Libbey-Owens-Ford (liquid) solar collector

    Science.gov (United States)

    1979-01-01

    Thermal performance tests were conducted on the Libbey-Owens-Ford liquid collector, following long term exposure to natural weathering conditions. Visual inspection of the collector, prior to the retest, indicated noticeable clouding of the inner cover glass, probably resulting from outgassing of the insulation. The absorber plate also showed some discoloration. The test results indicated that performance degradation had occurred at inlet temperatures significantly above ambient. The change in the slope of the efficiency curve, from the original data, is a direct indicator of an increase in the collector heat loss coefficient.

    Full Text Available L’articolo mostra le connessioni tra le idee economiche di alcuni importanti esponenti del socialismo utopistico britannico e le loro proposte su sistemi educativi alternativi. Nel XIX secolo, Robert Owen, John Ruskin e William Morris furono interessati alle condizioni dei lavoratori: il nucleo principale delle loro riflessioni fu la maniera di evitare lo sfruttamento delle masse dei lavoratori e salvare la bellezza nell’arte, nella natura e nella vita. Nonostante alcune importanti differenze tra i tre pensatori, Owen, Ruskin e Morris denunciarono i limiti e gli abusi del sistema capitalista. Pertanto loro suggerirono di superare il liberismo economico e, invece, di stabilire nuovi modelli socio-economici che avrebbero dovuto essere fondati su aziende cooperative (Owen, su corporazioni di lavoratori (Ruskin o su laboratori di artigiani (Morris. Le riflessioni dei tre pensatori prevedevano la necessità di cambiare il modello scolastico tradizionale, per contribuire alla riforma della società. L’articolo analizza le proposte educative di Owen, di Ruskin e di Morris alla luce delle loro riflessioni sociali, economiche e letterarie.

    2011-01-01

    J. Owen, M. M. Leach, B. Wampold, and E. Rodolfa (see record 2010-24976-001) tested the hypotheses that (a) some therapists express more multicultural competencies (MCCs) more than other therapists and (b) clients' perceptions of their therapists' MCCs are a function of specific client or therapeutic factors. In the present analysis, the authors critiqued 3 major components of the study: conceptual and methodological underpinnings, interpretation of research findings, and implications for future research. Although the authors agree with the importance of this line of research, the authors also believe that some of the researchers' underlying assumptions are worthy of examination; alternate interpretations of the findings are possible, and several recommendations for future research are imperative.

    Full Text Available RESUMEN. Este artículo tiene como hilo conductor la figura de sir Owen Williams (1890-1969, ingeniero y arquitecto. Su obra como ingeniero, con ejemplos de innegable valor como el trazado de la autopista M1 en Inglaterra, se equilibra con sus propuestas arquitectónicas y por ello el análisis de algunos ejemplos permite plantear una reflexión sobre aquello que es específico de ambas profesiones. No se pretende con ello elaborar una teoría para delinear el límite entre arquitectura e ingeniería, sino tratar de reconocer en sus edificios, con mirada de arquitecto, cualidades universales que, en su mayoría, son comunes a ingenieros y arquitectos. Se inicia el texto con la presentación del personaje y al desvelar su posición singular entre los profesionales y críticos de su época se entienden con mayor claridad los motivos de ese voluntario deambular de la arquitectura a la ingeniería. Las obras permiten enmarcar con mayor precisión su figura y dar respuesta a algunas cuestiones. El dominio de los avances tecnológicos y el rigor en el proyecto de estructuras de hormigón, ¿aproximan o distancian a arquitectos e ingenieros? Ser arquitecto e ingeniero al mismo tiempo, ¿enriquece o coarta la concepción, el diseño y el cálculo de las obras? Hombre riguroso, práctico, objeto de polémica y sin duda en todo momento atento a las innovaciones tecnológicas y a las posibilidades de los nuevos materiales. Así fue Owen Williams.SUMMARY. This article uses the figure of Sir Owen Williams (1890-1969, engineer and architect, as a conducting element. His work as an engineer, with examples of undeniable value such as the layout of the M1 motorway in England, balances with his architectural proposals. For that reason, the analysis of some examples of his work allows a reflection on what is specific to both professions. This is not to try to formulate a theory to delineate the limits between architecture and engineering, but to try to recognize

    2013-12-01

    Full Text Available Due to his untimely death in battle, Wilfred Owen was never able to publish his poems; his surviving work consists only of interrupted compositional processes. As a philological study of “The Send-Off” reveals, the available documentation is often problematic: Owen’s writing procedure is characterized by a non-linear path, dotted with a stream of unresolved textual possibilities. Through an analysis of the main tendencies which characterize “The Send-Off”, this article proposes to explore some new aspects of the texts. In particular, it sheds new light on a web of connections among recurring ideas and themes in the poem, which offers a complex and multifaceted picture of both the war experience and its effects on the soldiers.

    Ground-water quality in the approximately 1,630 square-mile Owens and Indian Wells Valleys study unit (OWENS) was investigated in September-December 2006 as part of the Priority Basin Project of Groundwater Ambient Monitoring and Assessment (GAMA) Program. The GAMA Priority Basin Project was developed in response to the Groundwater Quality Monitoring Act of 2001 and is being conducted by the U.S. Geological Survey (USGS) in collaboration with the California State Water Resources Control Board (SWRCB). The Owens and Indian Wells Valleys study was designed to provide a spatially unbiased assessment of raw ground-water quality within OWENS study unit, as well as a statistically consistent basis for comparing water quality throughout California. Samples were collected from 74 wells in Inyo, Kern, Mono, and San Bernardino Counties. Fifty-three of the wells were selected using a spatially distributed, randomized grid-based method to provide statistical representation of the study area (grid wells), and 21 wells were selected to evaluate changes in water chemistry in areas of interest (understanding wells). The ground-water samples were analyzed for a large number of synthetic organic constituents [volatile organic compounds (VOCs), pesticides and pesticide degradates, pharmaceutical compounds, and potential wastewater- indicator compounds], constituents of special interest [perchlorate, N-nitrosodimethylamine (NDMA), and 1,2,3- trichloropropane (1,2,3-TCP)], naturally occurring inorganic constituents [nutrients, major and minor ions, and trace elements], radioactive constituents, and microbial indicators. Naturally occurring isotopes [tritium, and carbon-14, and stable isotopes of hydrogen and oxygen in water], and dissolved noble gases also were measured to help identify the source and age of the sampled ground water. This study evaluated the quality of raw ground water in the aquifer in the OWENS study unit and did not attempt to evaluate the quality of treated water

    This special volume of aquatic geochemistry is dedicated to the memory of Owen Peterson Bricker III (1936–2011) and serves as a tribute to his life and career. Owen had a distinguished and productive research career in both academics at Johns Hopkins University (Fig. 1) and as a public servant with the Maryland Geological Survey, the US Environmental Protection Agency, and the US Geological Survey. He was a pioneer and leader in aqueous geochemistry, who applied a study approach that quantified mineral weathering reactions and equilibrium thermodynamic relations to better understand the chemical evolution of stream water in small watersheds. He will be especially remembered for his efforts to establish rigorous field studies in small catchments around the United States as a means of quantifying the sources of acid-neutralizing capacity that affect the chemical status and biological health of natural waters.

    2011-05-01

    Full Text Available The process of listing a World Heritage Area (WHAc in developing countries is often much more complex than in the West. Often all stakeholders are not taken into consideration and there is a lack of understanding of the concept of World Heritage and what it entails. This is particularly true for stakeholders who live in or adjacent to the proposed WHA, such as local communities. This paper presents a case study of Kokoda and the Owen Stanley Ranges, currently a tentative World Heritage site, to show the complexities in stakeholder collaboration and attribution in the process of World Heritage designation. Six key stakeholders were identified in the study. Upon examination of four attributes of stakeholders: power; legitimacy; urgency; and proximity, it was found that all stakeholders in this case study have a high legitimacy in the listing process however only the local community holds high levels of power, urgency and proximity. Additionally it was found that several stakeholders, like the private sector, have too many weak relationships with other stakeholders, resulting in a lack of communication. These findings present the first step in understanding how it might be possible to improve the listing process of World Heritage Sites in developing countries through effective stakeholder collaboration.

    Between September and November 1991, 12 Owen Stanley skinks, Papuascincus stanleyanus (Booulenger) were collected from various localities on Papua New Guinea and examined for coccidians. Six (50%) were found to harbour four eimerians that we describe here as new. Oocysts of Eimeria burseyi sp. n. were elongate to ellipsoidal with a bilayered wall and measured (length x width, L x W) 36.0 x 24.0 microm, with a L/W ratio of 1.5. Both micropyle and oocyst residuum were absent, but a polar granule was present. Oocysts of Eimeria goldbergi sp. n. were ellipsoidal, with a bilayered wall, and measured 21.4 x 16.1 microm; L/W ratio was 1.3. Both micropyle and oocyst residuum were absent, but a single or fragmented polar granule was present. Oocysts of Eimeria boulengeri sp. n. were spheroidal to slightly subspheroidal, with a thin, single-layered wall that readily collapses, and measured 16.0 microm, L/W ratio was 1.0. Both micropyle and oocyst residuum were absent, but usually one (sometimes two) polar granule(s) were present. Oocysts of Eimeria niuginiensis sp. n. were oblong to tapered with a bilayered wall, and measured 20.0 x 13.1 microm; L/W ratio was 1.5. A micropyle, oocyst residuum and polar granule were absent. To our knowledge, these represent the only coccidians ever described from P. stanleyanus.

    Robert Owen is not only a famous utopian socialist, but also excellent enterprise manager. the experiment what he did in New Larnak last for 30 years proves Robert Owen is the pioneer and model of corporate social responsibility(CSR). From Owen 's discussions about New Larnak Experiment, we can extract his views of CSR, they mainly refers to three as-pects: objective, feasibility and limitation. For the objective of CSR, Owen' s opinion is to realize the Win-Win between en-terprise and stakeholders under the precondition that enterprise can gain profit. For the feasibility of CSR, Owen' s opinion is that entrepreneurs and wage earners have common interests, taking good care of wage earners won' t damage the interest of entrepreneurs, but would expand commodity outlet and enhancing management efficiency. For the limitation of CSR, Owen' s opinion is that the effects of CSR would be restricted by capitalist mode of production necessarily. By means of exploring Owens views of CSR, we can obtain the enlightenment that coping with the contradiction between enterprises and society by developing CSR is feasible, but can only cure the symptoms.%罗伯特·欧文不仅是著名的空想社会主义者,也是卓越的企业管理者,他在新拉纳克所进行的30年试验证明了自己是企业社会责任的先驱和典范。从欧文关于新拉纳克试验的论述可以提炼出他的企业社会责任观,主要涉及三个方面问题:目的、可行性以及局限性。从目的来看,欧文认为企业履行社会责任只能是在以获取利润为根本的前提下实现企业与相关利益者的共赢;从可行性来看,欧文认为企业主与雇佣劳动者的利益是一致的,照顾好雇佣劳动者不但不会损害企业主的利益,反而会扩展商品销路和提升管理效率;从局限性来看,欧文认为企业履行社会责任所能产生的效果必然要受到资本主义生产方式的制约。发掘欧文的企业社

    ??18O, ??13C, total organic carbon, total inorganic carbon, and acid-leachable Li, Mg and Sr concentrations on 443 samples from 32 to 83 m depth in Owens Lake core OL-92 were analyzed to study the climatic and hydrological conditions between 60 and 155 ka with a resolution of ???200 a. The multi-proxy data show that Owens Lake overflowed during wet/cold conditions of marine isotope stages (MIS) 4, 5b and 6, and was closed during the dry/warm conditions of MIS 5a, c and e. The lake partially overflowed during MIS 5d. Our age model places the MIS 4/5 boundary at ca 72.5 ka and the MIS 5/6 boundary (Termination II) at ca 140 ka, agreeing with the Devils Hole chronology. The diametrical precipitation intensities between the Great Basin (cold/wet) and eastern China (cold/dry) on Milankovitch time scales imply a climatic teleconnection across the Pacific.

  15. Mark Bowden and Owen Sheers present "Creation" [working title]: a new musical and poetic collaborative project for chorus, soloists and orchestra

    CERN Multimedia

    2013-01-01

    "Creation" is a new collaboration between Mark Bowden, in his role as BBC National Orchestra of Wales’ Resident Composer, and the poet and novelist Owen Sheers.   Taking Haydn's 1798 work "The Creation" as a point of departure, they plan to create a new cantata for the digital age exploring the meaning of creation in the twenty-first century. Through engagement with developments in biology and physics they plan to create a new work incorporating poetry and music that will explore the latest ideas concerning the creation of matter and the emergence of life in the universe, whilst also delving into the human side of the brilliant minds that are currently working to uncover these secrets of the universe. More information is available here. Meet them at the CERN Library (bldg. 52 1-052) on Wednesday 2 October at 4 p.m. * Coffee will be served at 3.30 p.m.*

  16. Determining the origin of enigmatic bedrock structures using apatite (U-Th)/He thermochronology: Alabama and Poverty Hills, Owens Valley, California

    The Alabama and Poverty Hills are enigmatic, topographic highs of crystalline basement surrounded by Neogene sediments in Owens Valley, California. The 150-km long Owens Valley, the westernmost graben of the Basin and Range Province, initiated at about 3 Ma, creating ~2-4 km of vertical relief from the Sierra Nevada and White/Inyos crests to the valley floor. Along the valley, the active right-lateral Owens Valley Fault Zone (OVFZ) accommodates a significant portion of Pacific-North American plate motion, creating an oblique dextral fault zone, with localized transpression along minor left-stepovers. The dominantly granitic Mesozoic rocks of the Alabama Hills are bounded by the OVFZ to the east, and the granitic and metavolcanic Mesozoic rocks of the Poverty Hills are located along an apparent 3-km left stepover of the OVFZ. The tectonic origin and geodynamic significance of both these structures are not known, but previously published hypotheses include: 1) transpressional uplifts as OVFZ-related flower structures; 2) down-dropped normal fault blocks; and 3) giant landslides from adjacent ranges. We measured apatite (U-Th)/He ages on 15 samples from the Alabama and Poverty Hills to understand the history of shallow crustal exhumation of these structures, and to potentially correlate them to rocks from adjacent ranges. Apatite He dating typically yields cooling ages corresponding to closure temperatures of ~55-65 °C, corresponding roughly to depths of ~2-3 km in the crust. The majority of apatite He ages from the Alabama Hills ranged from 58-70 Ma, but the far eastern, and lowest elevation sample showed ages of 51-55 Ma. The Poverty Hills shows younger ages of 40-65 Ma and no recognizable spatial pattern. Although the data do not conclusively rule out a transpressional uplift origin of the Poverty Hills, the rocks within them could not have been exhumed from depths greater than ~2-3 km in Owens Valley. Data from both structures are most consistent with down

    basins are common features observed at releasing bends along major strike-slip faults. The formation and structural evolution of such basins have mostly been investigated in the continental domain and by sandbox laboratory experiments or numerical models. Here we present recently acquired multibeam bathymetry, 3.5 kHz echo sounder, and seismic profiles across the 20°N pull-apart Basin along the India-Arabia transform boundary, known as the Owen Fracture Zone (OFZ). Using nearby oceanic drilling (Deep Sea Drilling Project 222), we constrain the structural evolution of the basin since opening some 3 Myr ago. The 20°N Basin is large (90 km long and 35 km wide) despite limited transcurrent motion (~10 km). The first stage involved the formation of a step over along the OFZ and the subsequent isolation of a subsiding half graben. Extension and subsidence were further partitioned over three distinct subbasins separated by complex sets of transverse faults. The size of the basin was enhanced by gravity-driven collapse. The 20°N Basin has been a catchment for Indus turbidites since its opening, which provide a good record of syn-sedimentary deformation. The deformation related to the subsidence of the half graben mimics rollover structures commonly encountered in salt tectonics, suggesting that subsidence was accommodated by one or several décollement layers at depth. Despite a different rheological context, the subsurface structure of the nascent oceanic 20°N Basin is very similar to the more mature continental Dead Sea Basin along the Levant Fault, which also displays subbasins separated by transverse faults.

    Many people, not only at CERN but also throughout the world, were saddened to learn that their friend and colleague David Williams had passed away in the early hours of Tuesday 24 October. His death came after a year of fighting cancer with all of his usual determination and optimism. Even days before the end he was still welcoming to visitors, and was alert and interested in all their news. Born in 1944, David came to CERN from the University of Cambridge in 1966, with a degree in Physics and Computer Science. Joining what at the time was called the Documents and Data (DD) Division, in the earlier part his career he worked first on software for analysis of bubble chamber photographs, subsequently leading the group that supported experiments with 'hybrids' of bubble chambers and electronic detectors and then the group supporting online computing in experiments. He thus witnessed all of the enormous changes that took place in particle physics as the era of bubble chambers came to an end and the availability ...

  3. Ancient collagen reveals evolutionary history of the endemic South American 'ungulates'.

    2015-05-07

    Since the late eighteenth century, fossils of bizarre extinct creatures have been described from the Americas, revealing a previously unimagined chapter in the history of mammals. The most bizarre of these are the 'native' South American ungulates thought to represent a group of mammals that evolved in relative isolation on South America, but with an uncertain affinity to any particular placental lineage. Many authors have considered them descended from Laurasian 'condylarths', which also includes the probable ancestors of perissodactyls and artiodactyls, whereas others have placed them either closer to the uniquely South American xenarthrans (anteaters, armadillos and sloths) or the basal afrotherians (e.g. elephants and hyraxes). These hypotheses have been debated owing to conflicting morphological characteristics and the hitherto inability to retrieve molecular information. Of the 'native' South American mammals, only the toxodonts and litopterns persisted until the Late Pleistocene-Early Holocene. Owing to known difficulties in retrieving ancient DNA (aDNA) from specimens from warm climates, this research presents a molecular phylogeny for both Macrauchenia patachonica (Litopterna) and Toxodon platensis (Notoungulata) recovered using proteomics-based (liquid chromatography-tandem mass spectrometry) sequencing analyses of bone collagen. The results place both taxa in a clade that is monophyletic with the perissodactyls, which today are represented by horses, rhinoceroses and tapirs.

    虽然说圣西门、傅立叶和欧文阐发的空想社会主义属于乌托邦思想的一个新的理论阶段,但是在叙事话语和逻辑内核方面他们很大程度上承续了柏拉图和莫尔,即乌托邦思想中潜藏着共和主义叙事。不仅如此,空想社会主义作为一种共和主义叙事同样被遗忘于共和主义知识谱系之外。通过对相关文本的分析,我们着重从共和主义的视角对他们的空想社会主义进行了诠释,并希望将他们三个人的名字重新书写到共和主义的政治光谱之上。%Although the Utopian Socialism that was expounded by Saint-Simon,Charles Fourier and Robert Owen belongs to a new theoretical stage of Utopian thought,they inherited the narrative discourse and logical kernel of Plato and Moore to a great extent,and that is,a republican narrative has been hidden in Utopian thought.In addition,Utopian Socialism as a republican narrative is similarly forgotten outside the republican intellectual genealogy.By analysising related text,we emphatically make an interpretation to their Utopian Socialism from the Republican perspective,and hope to rewrite their names on the the republican political spectrum.

    Objective]The systemic long-lasting and broad-spectrum resistance of cucumber seedlings was induced with natural or synthetic compounds. The objective of this study is to shed light on the resistance induced by fluoro-substituted benzothiadiazole derivatives (FBT) to cucumber Fusarium wiltand provide data for elucidating its mechanism.[Method]Before transplanting, 50 mg·L-1 of FBT was used to spray so as to induce the cucumber seedlings at 3-4 true leaf stage. Three days later, the cucumber seedlings were transplanted into the soil withFusarium oxysporum f. sp.cucumerinum Owen, and sprayed with FBT so as to induce resistance for the second time. Sequently, the cucumber seedlings were sprayed every 7 days and for 3 times continuously. Meanwhile, contrast agent BTH also was used with the same induction method and 70% thiophanate-methyl at 1 500 times was applied through root-irrigation. The efficiency on the blight disease resistance was assessed through investigating disease index. For studying the influence of FBT on F. oxysporum f. sp.cucumerinum invasion of cucumber, the cucumber’s radicle length was sprouted to 0.5 cm and then the radicle immersed in 50 mg·L-1 of FBT. The resistance of cucumber seedlings was induced another time at the stage of 2 pieces of leaves. Since then, the cucumber seedlings were sprayed in order to induce the resistance every 7 days and total for 3 times. Twenty-four hours after the last induction, cucumber was inoculated withF. oxysporum f. sp.cucumerinum by the root-drenching method. Treated roots and the controls were harvested at 1, 3, 5, 7, 9, 11, 14, 16, 20, 24 and 29 days after inoculation and then cleaned in ice water. After induction, acid fuchsin dyeing technology was used to evaluate the FBT impacts on fusarium infection. In addition, the Maule reaction and toluidine blue staining technique were used to evaluate the change of lignin and phenolic substances in cucumber root tissue deposition. Moreover, metabolic alterations

    Directory of Open Access Journals (Sweden)

    Richard J. Blakely

    2013-04-01

    Full Text Available The tectonically active East Sierra Valley System (ESVS, which comprises the westernmost part of the Walker Lane-Eastern California Shear Zone, marks the boundary between the highly extended Basin and Range Province and the largely coherent Sierra Nevada-Great Valley microplate (SN-GVm, which is moving relatively NW. The recent history of the ESVS is characterized by oblique extension partitioned between NNW-striking normal and strike-slip faults oriented at an angle to the more northwesterly relative motion of the SN-GVm. Spatially variable extension and right-lateral shear have resulted in a longitudinally segmented valley system composed of diverse geomorphic and structural elements, including a discontinuous series of deep basins detected through analysis of isostatic gravity anomalies. Extension in the ESVS probably began in the middle Miocene in response to initial westward movement of the SN-GVm relative to the Colorado Plateau. At ca. 3–3.5 Ma, the SN-GVm became structurally separated from blocks directly to the east, resulting in significant basin-forming deformation in the ESVS. We propose a structural model that links high-angle normal faulting in the ESVS with coeval low-angle detachment faulting in adjacent areas to the east.

    Pikuta, Elena V.; Itoh, Takashi; Krader, Paul; Whitman, William B.; Hoover, Richard B.

    2006-01-01

    A novel, alkaliphilic, obligately anaerobic bacterium, strain SCAT, was isolated from mud sediments of a soda lake in California, USA. The rod-shaped cells were motile, Gram-positive, formed spores and were 0.4-0.5x2.5-5.0 micrometers in size. Growth occurred within the pH range 6.7-10.0 and was optimal at pH 8.5. The temperature range for growth was 10-45 degrees C, with optimal growth at 35 degrees C. NaCl was required for growth. Growth occurred at 0.5-9.0% (w/v) NaCl and was optimal at 1-2% (w/v). The novel isolate was a catalase-negative chemo-organoheterotroph that fermented sugars, proteolysis products, some organic and amino acids, glycerol, d-cellobiose and cellulose. It was also capable of growth by the Stickland reaction. Strain SCAT was sensitive to tetracycline, chloramphenicol, rifampicin and gentamicin, but it was resistant to ampicillin and kanamycin. The G+C content of the genomic DNA was 34.2 mol%. Major fatty acid components were C14:0, iso-C15:0, C16:1omega9c and C16:0. 16S rRNA gene sequence analysis of strain SCAT showed a similarity of approximately 97% with the type strains of Clostridium formicaceticum and Clostridium aceticum in clostridial cluster XI and a similarity of less than 94.2% to any other recognized Clostridium species and those of related genera in this cluster. Strain SCAT was clearly differentiated from C. formicaceticum and C. aceticum based on comparison of their phenotypic properties and fatty acid profiles, as well as low levels of DNA-DNA relatedness between strain SCAT and the type strains of these two species. Therefore, strain SCAT is considered to represent a novel species of a new genus, Anaerovirgula multivorans gen. nov., sp. nov., in clostridial cluster XI. The type strain is SCAT (=ATCC BAA-1084T=JCM 12857T=DSM 17722T=CIP 107910T).

The differences also relate to body size and proportions, female D. conicus n. sp. being, on average slightly larger, and male significantly larger than D. auricularis. Males of the new species also have longer and more massive opisthosoma than males of D. auricularis. Demodex conicus n. sp. was found in 17.5% of the mice studied from different locations in Poland.

    Corporate museums make important contributions to science history and daily life. They are an essential part of the historical marketing of organizations, including scientific associations. The museum for the history of urology organized and housed by the German Society of Urology (DGU) can be compared to a corporate museum, because the institution serves two purposes: it represents the society to a wider public and it helps to reconstruct and analyze the history of urology and the history of the society. In a close collaboration with medical historians from all over the world the museum serves as a research institution for the history of urology. The institution is founded at the frontier between a commercial corporate museum similar to that of international companies and a classical scientific museum. The paper describes these aspects of the museum and discusses the inherent value of a museum for a scientific association.

    Morphological abnormalities were observed on the cephalic bulb hooklets of advanced third-stage larvae (AdvL(3)) of genus Gnathostoma. The larvae were obtained from the fish "Mexican rivulus" Millerichthys robustus collected from a seasonal pond near Tlacotalpan, Veracruz, Mexico. The abnormalities involved (1) extra rudimentary hooklets, located between the four rows and after the fourth row, (2) branched or lobulated hooklets, and (3) fragmented hooklets not uniformly disposed in rows. The alterations observed on the cephalic bulb hooklets do not represent intraspecific variations, and they may be considered as a potential tool for assessing the presence of pollutants or stressors located within the ecosystem.

    No large group of recently extinct placental mammals remains as evolutionarily cryptic as the approximately 280 genera grouped as 'South American native ungulates'. To Charles Darwin, who first collected their remains, they included perhaps the 'strangest animal[s] ever discovered'. Today, much like 180 years ago, it is no clearer whether they had one origin or several, arose before or after the Cretaceous/Palaeogene transition 66.2 million years ago, or are more likely to belong with the elephants and sirenians of superorder Afrotheria than with the euungulates (cattle, horses, and allies) of superorder Laurasiatheria. Morphology-based analyses have proved unconvincing because convergences are pervasive among unrelated ungulate-like placentals. Approaches using ancient DNA have also been unsuccessful, probably because of rapid DNA degradation in semitropical and temperate deposits. Here we apply proteomic analysis to screen bone samples of the Late Quaternary South American native ungulate taxa Toxodon (Notoungulata) and Macrauchenia (Litopterna) for phylogenetically informative protein sequences. For each ungulate, we obtain approximately 90% direct sequence coverage of type I collagen α1- and α2-chains, representing approximately 900 of 1,140 amino-acid residues for each subunit. A phylogeny is estimated from an alignment of these fossil sequences with collagen (I) gene transcripts from available mammalian genomes or mass spectrometrically derived sequence data obtained for this study. The resulting consensus tree agrees well with recent higher-level mammalian phylogenies. Toxodon and Macrauchenia form a monophyletic group whose sister taxon is not Afrotheria or any of its constituent clades as recently claimed, but instead crown Perissodactyla (horses, tapirs, and rhinoceroses). These results are consistent with the origin of at least some South American native ungulates from 'condylarths', a paraphyletic assembly of archaic placentals. With ongoing

  6. Mitogenomic phylogenetics of fin whales (Balaenoptera physalus spp.: genetic evidence for revision of subspecies.

    Directory of Open Access Journals (Sweden)

    Frederick I Archer

    Full Text Available There are three described subspecies of fin whales (Balaenoptera physalus: B. p. physalus Linnaeus, 1758 in the Northern Hemisphere, B. p. quoyi Fischer, 1829 in the Southern Hemisphere, and a recently described pygmy form, B. p. patachonica Burmeister, 1865. The discrete distribution in the North Pacific and North Atlantic raises the question of whether a single Northern Hemisphere subspecies is valid. We assess phylogenetic patterns using ~16 K base pairs of the complete mitogenome for 154 fin whales from the North Pacific, North Atlantic--including the Mediterranean Sea--and Southern Hemisphere. A Bayesian tree of the resulting 136 haplotypes revealed several well-supported clades representing each ocean basin, with no haplotypes shared among ocean basins. The North Atlantic haplotypes (n = 12 form a sister clade to those from the Southern Hemisphere (n = 42. The estimated time to most recent common ancestor (TMRCA for this Atlantic/Southern Hemisphere clade and 81 of the 97 samples from the North Pacific was approximately 2 Ma. 14 of the remaining North Pacific samples formed a well-supported clade within the Southern Hemisphere. The TMRCA for this node suggests that at least one female from the Southern Hemisphere immigrated to the North Pacific approximately 0.37 Ma. These results provide strong evidence that North Pacific and North Atlantic fin whales should not be considered the same subspecies, and suggest the need for revision of the global taxonomy of the species.

    Directory of Open Access Journals (Sweden)

    Sergio F. Vizcaíno

    2009-04-01

    Full Text Available Duringhis two years in South America Charles Darwin became fascinated not only withthe lush vegetation of Brazil, but also with the gigantic Pleistocene mammals that hefound in the drier areas of Uruguay, and in the pampas and Patagonian coast of Argentina. These findings includedvarious ground sloths and glyptodonts among xenarthrans, and hoofed herbivoreslike Toxodon and Macrauchenia, in addition to horses and smallrodents. He concluded that the general assumption that large animals requireluxuriant vegetation was false and that vitiated the reasoning of geologists onsome aspects of Earth's history. He also reflected on the evident changes thatoccurred in the continent, the extinct fauna of which suggested to him ananalogy to southern parts of Africa. He wondered about our ignorance of biological traits inextinct creatures and the reasons for their extinction. Thus, not only did Darwin inspire phylogeneticstudies on fossil mammal lineages, he also opened a gate to the research ontheir behaviour, physiology and extinction; i.e., their palaeobiology. Whereasthe first approach was largely developed in South America beginning about thesecond half of the 19th century due to the intellectual influence ofFlorentino Ameghino, palaeobiology became a much more recent line of work, inapparent relation to innovations in methodology and technology. Thiscontribution provides an overview of recent contributions on the palaeobiologyof Pleistocene fossil mammals of South America as attempts to provide answers for Darwin's questions.

    Full Text Available Duringhis two years in South America Charles Darwin became fascinated not only withthe lush vegetation of Brazil, but also with the gigantic Pleistocene mammals that hefound in the drier areas of Uruguay, and in the pampas and Patagonian coast of Argentina. These findings includedvarious ground sloths and glyptodonts among xenarthrans, and hoofed herbivoreslike Toxodon and Macrauchenia, in addition to horses and smallrodents. He concluded that the general assumption that large animals requireluxuriant vegetation was false and that vitiated the reasoning of geologists onsome aspects of Earth's history. He also reflected on the evident changes thatoccurred in the continent, the extinct fauna of which suggested to him ananalogy to southern parts of Africa. He wondered about our ignorance of biological traits inextinct creatures and the reasons for their extinction. Thus, not only did Darwin inspire phylogeneticstudies on fossil mammal lineages, he also opened a gate to the research ontheir behaviour, physiology and extinction; i.e., their palaeobiology. Whereasthe first approach was largely developed in South America beginning about thesecond half of the 19th century due to the intellectual influence ofFlorentino Ameghino, palaeobiology became a much more recent line of work, inapparent relation to innovations in methodology and technology. Thiscontribution provides an overview of recent contributions on the palaeobiologyof Pleistocene fossil mammals of South America as attempts to provide answers for Darwin's questions.Durante los dos añosque Charles Darwin estuvo en América del Sur no sólo se deslumbró con laprofusa vegetación de Brasil, si no también con los gigantescos mamíferospleistocenos que colectó en áreas más secas de Uruguay y en la pampa y la costapatagónica de Argentina. Sus hallazgos incluyeron distintos perezosos ygliptodontes, ungulados herbívoros como Toxodon y Macrauchenia,además de caballos y pequeños roedores

    Individual carbon nanotubes were immersed and removed from various organic liquids using atomic force microscopy. The carbon nanotube-liquid interactions could be monitored in situ, and accurate measurements of the contact angle between liquids and the nanotube surface were made. These wetting data were used to produce Owens and Wendt plots giving the dispersive and polar components of the nanotube surface.

  4. Surface Properties of PEMFC Gas Diffusion Layers

    Energy Technology Data Exchange (ETDEWEB)

    WoodIII, David L [Los Alamos National Laboratory (LANL); Rulison, Christopher [Augustine Scientific; Borup, Rodney [Los Alamos National Laboratory (LANL)

    2010-01-01

    The wetting properties of PEMFC Gas Diffusion Layers (GDLs) were quantified by surface characterization measurements and modeling of material properties. Single-fiber contact-angle and surface energy (both Zisman and Owens-Wendt) data of a wide spectrum of GDL types is presented to delineate the effects of hydrophobic post-processing treatments. Modeling of the basic sessile-drop contact angle demonstrates that this value only gives a fraction of the total picture of interfacial wetting physics. Polar forces are shown to contribute 10-20 less than dispersive forces to the composite wetting of GDLs. Internal water contact angles obtained from Owens-Wendt analysis were measured at 13-19 higher than their single-fiber counterparts. An inverse relationship was found between internal contact angle and both Owens-Wendt surface energy and % polarity of the GDL. The most sophisticated PEMFC mathematical models use either experimentally measured capillary pressures or the standard Young-Laplace capillary-pressure equation. Based on the results of the Owens-Wendt analysis, an advancement to the Young-Laplace equation is proposed for use in these mathematical models, which utilizes only solid surface energies and fractional surface coverage of fluoropolymer. Capillary constants for the spectrum of analyzed GDLs are presented for the same purpose.

  16. Continuous lake-sediment records of glaciation in the Sierra Nevada between 52,600 and 12,500 14C yr B.P.

    1998-01-01

    The chemistry of the carbonate-free clay-size fraction of Owens Lake sediments supports the use of total organic carbon and magnetic susceptibility as indicators of stadial-interstadial oscillations. Owens Lake records of total organic carbon, magnetic susceptibility, and chemical composition of the carbonate-free, clay-size fraction indicate that Tioga glaciation began ~24,500 and ended by ~13,600 14C yr B.P. Many of the components of glacial rock flour (e.g., TiO2, MnO, BaO) found in Owens Lake sediments achieved maximum values during the Tioga glaciation when valley glaciers reached their greatest extent. Total organic carbon and SiO2 (amorphous) concentrations reached minimum values during Tioga glaciation, resulting from decreases in productivity that accompanied the introduction of rock flour into the surface waters of Owens Lake. At least 20 stadial-interstadial oscillations occurred in the Sierra Nevada between 52,600 and 14,000 14C yr B.P. Total organic carbon data from a Pyramid Lake sediment core also indicate oscillations in glacier activity between >39,500 and ~13,600 14C yr B.P. Alpine glacier oscillations occurred on a frequency of ???1900 yr in both basins, suggesting that millennial-scale oscillations occurred in California and Nevada during most of the past 52,600 yr.

  5. Reconstructing late Pliocene to middle Pleistocene Death Valley lakes and river systems as a test of pupfish (Cyprinodontidae) dispersal hypotheses

    Knott, J.R.; Machette, M.N.; Klinger, R.E.; Sarna-Wojcicki, A. M.; Liddicoat, J.C.; Tinsley, J. C.; David, B.T.; Ebbs, V.M.

    2008-01-01

    During glacial (pluvial) climatic periods, Death Valley is hypothesized to have episodically been the terminus for the Amargosa, Owens, and Mojave Rivers. Geological and biological studies have tended to support this hypothesis and a hydrological link that included the Colorado River, allowing dispersal of pupfish throughout southeastern California and western Nevada. Recent mitochondrial deoxyribonucleic acid (mtDNA) studies show a common pupfish (Cyprinodontidae) ancestry in this region with divergence beginning 3-2 Ma. We present tephrochronologic and paleomagnetic data in the context of testing the paleohydrologic connections with respect to the common collection point of the Amargosa, Owens, and Mojave Rivers in Death during successive time periods: (1) the late Pliocene to early Pleistocene (3-2 Ma), (2) early to middle Pleistocene (1.2-0.5 Ma), and (3) middle to late Pleistocene (<0.70.03 Ma; paleolakes Manly and Mojave). Using the 3.35 Ma Zabriskie Wash tuff and 3.28 Ma Nomlaki Tuff Member of the Tuscan and Tehama Formations, which are prominent marker beds in the region, we conclude that at 3-2 Ma, a narrow lake occupied the ancient Furnace Creek Basin and that Death Valley was not hydrologically connected with the Amargosa or Mojave Rivers. A paucity of data for Panamint Valley does not allow us to evaluate an Owens River connection to Death Valley ca. 3-2 Ma. Studies by others have shown that Death Valley was not hydrologically linked to the Amargosa, Owens, or Mojave Rivers from 1.2 to 0.5 Ma. We found no evidence that Lake Manly flooded back up the Mojave River to pluvial Lake Mojave between 0.18 and 0.12 Ma, although surface water flowed from the Amargosa and Owens Rivers to Death Valley at this time. There is also no evidence for a connection of the Owens, Amargosa, or Mojave Rivers to the Colorado River in the last 3-2 m.y. Therefore, the hypothesis that pupfish dispersed or were isolated in basins throughout southeastern California and western

  6. Homology, homoplasy, novelty, and behavior.

    Science.gov (United States)

    Hall, Brian K

    2013-01-01

    Richard Owen coined the modern definition of homology in 1843. Owen's conception of homology was pre-evolutionary, nontransformative (homology maintained basic plans or archetypes), and applied to the fully formed structures of animals. I sketch out the transition to an evolutionary approach to homology in which all classes of similarity are interpreted against the single branching tree of life, and outline the evidence for the application of homology across all levels and features of the biological hierarchy, including behavior. Owen contrasted homology with analogy. While this is not incorrect it is a pre-evolutionary contrast. Lankester [Lankester [1870] Journal of Natural History, 6 (31), 34-43] proposed homoplasy as the class of homology applicable to features formed by independent evolution. Today we identify homology, convergence, parallelism, and novelties as patterns of evolutionary change. A central issue in homology [Owen [1843] Lectures on comparative anatomy and physiology of the invertebrate animals, delivered at the Royal College of Surgeons in 1843. London: Longman, Brown, Green & Longmans] has been whether homology of features-the "same" portion of the brain in different species, for example-depends upon those features sharing common developmental pathways. Owen did not require this criterion, although he observed that homologues often do share developmental pathways (and we now know, often share gene pathways). A similar situation has been explored in the study of behavior, especially whether behaviors must share a common structural, developmental, neural, or genetic basis to be classified as homologous. However, and importantly, development and genes evolve. As shown with both theory and examples, morphological and behavioral features of the phenotype can be homologized as structural or behavioral homologues, respectively, even when their developmental or genetic bases differ (are not homologous).

    Full Text Available To determine who has the power within a stock corporate company can be a quite complex problem, especially when control is achieved through alliances between shareholders. This problem arises especially in cases of indirect control of corporations, that is, in situations involving shareholders and companies with cross-shareholdings. The first to solve the problem of measuring power in the case of indirect share control were Gianfranco Gambarelli and Guillermo Owen in [10]. In the following years, numerous other models were introduced. In this paper, we critically examine the models of: Gambarelli and Owen, Denti and Prati, Crama and Leruth, Karos and Peters, as well as Mercik and Lobos, taking into account two well-known, illustrative examples, one with an acyclic corporate structure and the other with a cyclic structure.

  9. Thomas Huxley and the rat placenta in the early debates on evolution.

    Pijnenborg, R; Vercruysse, L

    2004-01-01

    The 19th century debates on mammalian classification in the light of the new evolutionary thinking led to controversies between Thomas Huxley and Richard Owen concerning the value of the placenta as a representative key organ. As a main point in his argument, Huxley provided a detailed description of a sectioned rat placenta, highlighting the importance of decidualization of the uterus as an argument supporting an evolutionary relationship between rodents, insectivores and primates, an idea hotly contested by Owen. In addition, he illustrated and correctly interpreted the maternal blood supply from uterus to placenta in striking detail. During the succeeding decades the key role of trophoblast in placenta formation was discovered, and the decidua became neglected in later comparative studies. Nevertheless, at the present time trophoblast-decidual interaction is regarded as an extremely important feature of placental development in both primates and rodents, and Huxley can therefore rightfully be considered as an early pioneer in placental research.

    Students with autism display sensory sensitivities to environmental stimuli that affect their attending and engagement in classroom learning activities. The purpose of the study was to determine whether attending of 4 male students, ages 13-20, increased after the installation of sound-absorbing walls and halogen lighting. The multiple single-subject, mixed-method design, AB(B+C), included a 2-wk baseline and two intervention phases: 2 wk after sound-absorbing wall installation using the Owens Corning Basement Finishing System™ (Owens Corning, Toledo, OH) and 2 wk after halogen light installation. We calculated nonattending frequencies from videotaped class sessions and used visual analysis to measure within-phase and between-phase characteristics. Results included increased frequency and stability of attending and engagement and improved classroom performance, comfort, and mood. Journaling provided students' perspective on the modifications and reflected overall increased sensory comfort and themes of improved classroom environment, positive emotional response (mood), and improved classroom performance.

    Gnathostomiasis is a famous zoonotic disease caused by the larval nematodes of the genus Gnathostoma. Almost all of the causative agents recovered from the human cases in the past Japan have been identified with Gnathostoma spinigerum Owen, 1936. However, some of the recent cases were demonstrated to be due to some other gnathostome species, and attentions have been attracted to these non-spinigerum species. This report will cover the larvae of a non-spinigerum gnathostome collected from a sp...

    2013-12-01

    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

  9. Was Darwin a creationist?

    Science.gov (United States)

    Cosans, Chris

    2005-01-01

    Throughout the Origin of Species, Darwin contrasts his theory of natural selection with the theory that God independently created each species. This makes it seem as though the Origin offers a scientific alternative to a theological worldview. A few months after the Origin appeared, however, the eminent anatomist Richard Owen published a review that pointed out the theological assumptions of Darwin's theory. Owen worked in the tradition of rational morphology, within which one might suggest that evolution occurs by processes that are continuous with those by which life arises from matter; in contrast, Darwin rested his account of life's origins on the notion that God created one or a few life forms upon which natural selection could act. Owen argued that Darwin's reliance on God to explain the origins of life makes his version of evolution no less supernatural than the special creationist that Darwin criticizes: although Darwin limits God to one or a few acts of creation, he still relies upon God to explain life's existence.

  10. Biological hydrogen production measured in batch anaerobic respirometers.

    Science.gov (United States)

    Logan, Bruce E; Oh, Sang-Eun; Kim, In S; Van Ginkel, Steven

    2002-06-01

    The biological production of hydrogen from the fermentation of different substrates was examined in batch tests using heat-shocked mixed cultures with two techniques: an intermittent pressure release method (Owen method) and a continuous gas release method using a bubble measurement device (respirometric method). Under otherwise identical conditions, the respirometric method resulted in the production of 43% more hydrogen gas from glucose than the Owen method. The lower conversion of glucose to hydrogen using the Owen protocol may have been produced by repression of hydrogenase activity from high partial pressures in the gastight bottles, but this could not be proven using a thermodynamic/rate inhibition analysis. In the respirometric method, total pressure in the headspace never exceeded ambient pressure, and hydrogen typically composed as much as 62% of the headspace gas. High conversion efficiencies were consistently obtained with heat-shocked soils taken at different times and those stored for up to a month. Hydrogen gas composition was consistently in the range of 60-64% for glucose-grown cultures during logarithmic growth but declined in stationary cultures. Overall, hydrogen conversion efficiencies for glucose cultures were 23% based on the assumption of a maximum of 4 mol of hydrogen/ mol of glucose. Hydrogen conversion efficiencies were similar for sucrose (23%) and somewhat lower for molasses (15%) but were much lower for lactate (0.50%) and cellulose (0.075%).

    The traditional approach of the reception of Copernicus' ideas in Hungary was to trace the appearance of the heliocentric theory in various publications. The publishing of several book lists recently -- inventories or wills for example -- makes a different approach possible, one that is a continuation of Owen Gingerich's monumental "An Annotated Census of Copernicus' De revolutionibus". We collected from the published book lists all possible Copernicus copies and investigated their histories. Four of them were already known, here we add 14 more examples, ten of them missing. Two of the remaining four that are still in existence can be found in Transylvania, Romania, while two others are in Hungary.

    An earth-Mars depletion formula proposed by Anders and Owen for volatiles is used to calculate a range of putative Hg levels for Martian volcanic soils based upon analyzed samples from Hawaii. The range is about 50-150 microgram per kg. When applied either in conventional or special media (e.g., basalt powder), these levels of Hg are effective inhibitors of the growth of earth microorganisms. Taken together with other hostile chemical and physical factors, volcanic toxicants would appear to provide a further deterrent to the accidental establishment of terrestrial microbiota on Mars.

    Owens Corning has recently introduced the HiPer-texTM family of high performance reinforcements of which WindStrandTM is engineered to specific customer process requirements of resin infusion and prepregs for Wind Turbine blades manufacture. The new HiPer-tex technology platform enables up to 35% higher strength, 17% higher modulus, better impact, corrosion and high temperature resistance and significantly better fatigue properties versus traditional E Glass laminates. These attributes have been measured with various laminates types and are presented in this paper. These better performances are needed in markets such as Wind Energy, pressure vessels, armour, aerospace and light weight structural component. (au)

    It is suggested that motion along the virtually aseismic Owen fracture zone is negligible, so that Arabia and India are contained within a single Indo-Arabian plate divided from the Australian plate by a diffuse boundary. The boundary is a zone of concentrated seismicity and deformation commonly characterized as 'intraplate'. The rotation vector of Australia relative to Indo-Arabia is consistent with the seismologically observed 2 cm/yr of left-lateral strike-slip along the Ninetyeast Ridge, north-south compression in the Central Indian Ocean, and the north-south extension near Chagos.

    Gondwana breakup since the Jurassic and the northward motion of India toward Eurasia were associated with formation of ocean basins and ophiolite obduction between and onto the Indian and Arabian margins. Here we reconcile marine geophysical data from preserved oceanic basins with the age and location of ophiolites in NW India and SE Arabia and seismic tomography of the mantle below the NW Indian Ocean. The North Somali and proto-Owen basins formed due to 160-133-Ma N-S extension between Indi...

    Fiber-reinforced composites offer significant weight reduction potential, with glass fiber composites already widely adopted. Carbon fiber composites deliver the greatest performance benefits, but their high cost has inhibited widespread adoption. This project demonstrates that hybrid carbon-glass solutions can realize most of the benefits of carbon fiber composites at much lower cost. ORNL and Owens Corning Reinforcements along with program participants at the ORISE collaborated to demonstrate methods for produce hybrid composites along with techniques to predict performance and economic tradeoffs. These predictions were then verified in testing coupons and more complex demonstration articles.

    Silicone coatings have been used in this study. The method adopted was the liquid drop analysis on the coated fabrics. The contact angle between a liquid drop and the fabric surface was measured with two liquids continuously and recorded by a computer. The surface energy was calculated by means of Owens method.Kinetic measurement was adopted. The contact angle of liquids on the fabric coated silicone decreased with time was found. A compound solution DX has been found, so that the contact angle of the liquids on the fabric washed with DX becomes constant, and the surface energy of the fabric can be reduced to below 15 mJ/m2.

    This paper summarizes available data on worker exposures to asphalt fume (soluble fraction), total particulate matter, and respirable crystalline silica (quartz) [hereinafter RCS] over a 30-year period in Owens Corning's asphalt production and roofing manufacturing plants. For the period 1977 through 2006, the air-monitoring database contains more than 1,400 personal samples for asphalt fume (soluble fraction), 2,400 personal samples for total particulate, and 1,300 personal samples for RCS. Unique process-job categories were identified for the asphalt production and roofing shingle manufacturing plants. Quantitative exposures were tabulated by agent, process-job, and calendar period to form an exposure matrix for use in subsequent epidemiologic studies of the respiratory health of these workers. Analysis of time trends in exposure data shows substantial and statistically significant exposure reductions for asphalt fume (soluble fraction), total particulate matter, and respirable crystalline silica at Owens Corning plants. Cumulative distribution plots for the most recent sampling period (2001-2006) show that 95% of the asphalt fume (soluble fraction) measurements were less than 0.25 mg/m3; 95% of the total particulate measurements were less than 2.2 mg/m3; and 95% of the RCS measurements were less than 0.05 mg/m3. Several recommendations are offered to improve the design of future monitoring efforts.

  20. Recovery Act. Advanced Building Insulation by the CO2 Foaming Process

    Energy Technology Data Exchange (ETDEWEB)

    Yang, Arthur [Industrial Science and Technology Network, Inc., Lancaster, PA (United States)

    2013-12-30

    In this project, ISTN proposed to develop a new "3rd" generation of insulation technology. The focus was a cost-effective foaming process that could be used to manufacture XPS and other extruded polymer foams using environmentally clean blowing agents, and ultimately achieve higher R-values than existing products while maintaining the same level of cost-efficiency. In the U.S., state-of-the-art products are primarily manufactured by two companies: Dow and Owens Corning. These products (i.e., STYROFOAM and FOAMULAR) have a starting thermal resistance of R-5.0/inch, which declines over the life of the product as the HFC blowing agents essential to high R-value exchange with air in the environment. In the existing technologies, the substitution of CO2 for HFCs as the primary foaming agent results in a much lower starting R-value, as evidenced in CO2-foamed varieties of XPS in Europe with R-4.2/inch insulation value. The major overarching achievement from this project was ISTN's development of a new process that uses CO2 as a clean blowing agent to achieve up to R-5.2/inch at the manufacturing scale, with a production cost on a per unit basis that is less than the cost of Dow and Owens Corning XPS products.

    At present, the adhesion of asphalt-stone system is mainly studied by using surface free energy theory. Though sessile drop method, this paper has detected the contact angle of asphalt between 3 different polar liquid, and analyzed the effect on test results from two kinds of titration method, gravity drip method and moving liquid dripping method. The results show that the liquid dripping method has better reproducibility than gravity drip method, and is less susceptible to external interference. Finally, based on the Owens-Wendt theory, the surface free energy of asphalt was determined.%目前主要应用表面自由能理论对沥青-石料体系的粘附性进行研究。本文利用躺滴法,通过确定沥青与3种不同极性液体之间的接触角,重点对比分析了两种滴定方法(重力滴落法、移液滴落法)对测试结果的影响。结果表明:移液滴落法所得的数据重现性更好,不易受外界环境干扰。最后以Owens-Wendt 理论为基础,确定了沥青的表面自由能。

  2. On the Flow Behavior in Rotor-Stator System with Superposed Flow

    Directory of Open Access Journals (Sweden)

    Roger Debuchy

    2008-01-01

    Full Text Available The flow between a rotor and a stator at high Reynolds number and small Ekman number is divided into three domains, two boundary layers adjacent to the discs separated by a central core. In the present work, a simple theoretical approach provides analytical solutions for the radial distribution of the core swirl ratio valid for a rotor-stator system with a superposed radial inflow rate. At first, the flow in the rotor boundary layer is assumed to behave as expressed by Owen and Rogers (1989 in the case of a turbulent flow on a rotating single disc. On the stator side, a necessary compensation flow rate must take place according to the conservation of mass. It is found that this compensation flow rate cannot be estimated with a good accuracy using the hypotheses of a stationary disc in a rotating fluid by Owen and Rogers (1989. Thus, two innovative weighting functions are tested, leading to new analytical laws relating the core swirl ratio K to the coefficient of flow rate Cqr introduced by Poncet et al. (2005. The adequacy between the theoretical solutions and numerous results of the literature is clearly improved and the discussion allows a better understanding of the flow behavior.

  3. SMM observations of gamma-ray transients. 2: A search for gamma-ray lines between 400 and 600 keV from the Crab Nebula

    Science.gov (United States)

    Harris, Michael J.; Share, Gerald H.; Leising, Mark D.

    1994-01-01

    We have search spectra obtained by the Solar Maximum Mission Gamma-Ray Spectrometer during 1981-1988 for evidence of transient gamma-ray lines from the Crab Nebula which have been reported by previous experiments at energies 400-460 keV and 539 keV. We find no evidence for significant emission in any of these lines on time scales between aproximately 1 day and approximately 1 yr. Our 3 sigma upper limits on the transient flux during 1 d intervals are approximately equal to 2.2 x 10(exp -3) photons/sq cm/s for narrow lines at any energy, and approximately equal to 2.9 x 10(exp -3) photons/sq cm/s for the 539 keV line if it is as broad as 42 keV Full Width at Half Maximum (FWHM). We also searched our data during the approximately 5 hr period on 1981 June 6 during which Owens, Myers, & Thompson (1985) reported a strong line at 405 keV. We detected no line down to a 3 upper sigma limit of 3.3 x 10(exp -3) photons/sq cm/s in disagreement with the flux 7.2 +/- 2.1 x 10(exp -3) photos/sq cm/s measured by Owens et al.

  4. Simulation of Driving in Low-Visibility Conditions: Does Stereopsis Improve Speed Perception?

    Science.gov (United States)

    Brooks, Kevin R; Rafat, Mohammed E

    2015-02-01

    Laboratory-based studies of perceived speed show that, under most circumstances, perceived speed is reduced as a function of contrast. However, a recent investigation of perceived vehicular speed while driving around a closed road circuit showed no such effect (Owens, Wood, & Carberry, 2010, Perception, 39: , 1199-1215). We sought to probe the source of this discrepancy, asking whether the presence or absence of stereoscopic motion information might account for the difference in results. In a two-alternative forced-choice psychophysical speed-discrimination task, observers compared the speed of high- and low-contrast driving clips filmed with a 3-D camera and presented either stereoscopically (3-D) or monoscopically (2-D). Although perceived speed was reduced at low contrast, the size of this misperception was equivalent for 2-D and 3-D presentations. However, the inclusion of stereoscopic cues to vehicular speed caused significant improvements in the precision of speed judgments. It is concluded that although stereopsis can provide access to valuable information on perceived speed, contrast-independent speed estimation as demonstrated by Owens et al. (2010) is more likely to reflect the use of the full visual field in a real driving situation (compared with limited field of view simulations), or the additional contributions of nonvisual cues rather than stereopsis.

The effects of different anti-stripping agents and its complex with polyphosphoric acid on the surface free energy of asphalt binder were evaluated. The results indicate that the antistripping agents increase the surface free energy of asphalt binder and the adhesion ability between asphalt and aggregate,which enhances the moisture damage resistance of asphalt. The addition of anti-stripping agents with polyphosphoric acid can reduce the surface free energy of asphalt binder.%测定沥青与不同液体的接触角,利用Owen-Wendt法确定沥青的表面自由能,考察不同抗剥落剂及其与多聚磷酸的复配对沥青表面自由能的影响.结果表明:抗剥落剂的加人增加了沥青的表面自由能,提高了沥青一集料界面黏附能力,可增强沥青混合料的抗水损害能力;抗剥落剂与多聚磷酸的复配可降低沥青的表面自由能.

    2014-07-01

    The Body-Object Interaction (BOI) variable measures how easily a human body can physically interact with a word's referent (Siakaluk, Pexman, Aguilera, Owen, & Sears, ). A facilitory BOI effect has been observed with adults in language tasks, with faster and more accurate responses for high BOI words (e.g., mask) than for low BOI words (e.g., ship; Wellsby, Siakaluk, Owen, & Pexman, ). We examined the development of this effect in children. Fifty children (aged 6-9 years) and a group of 21 adults completed a word naming task with high and low BOI words. Younger children (aged 6-7 years) did not show a BOI effect, but older children (aged 8-9 years) showed a significant facilitory BOI effect, as did adults. Magnitude of children's BOI effect was related to age as well as reading skills. These results suggest that bodily experience (as measured by the BOI variable) begins to influence visual word recognition behavior by about 8 years of age.

  8. On the Surface Free Energy of PVC/EVA Polymer Blends: Comparison of Different Calculation Methods.

    Michalski; Hardy; Saramago

    1998-12-01

    The surface free energy of polymeric films of polyvinylchloride (PVC) + poly(ethylene-co-vinylacetate) (EVA) blends was calculated using the van Oss treatment (Lifshitz and electron donor-electron acceptor components of surface free energy) and the Owens-Wendt treatment (dispersive and nondispersive components of surface free energy). Surface free energy results were found to be greatly dependent on the calculation method and on the number of standard liquids used for contact angle measurements. The nondispersive/donor-acceptor surface free energy component and the total surface free energy of polymeric films were always higher when the van Oss treatment was used compared to the Owens-Wendt treatment. Conversely, both methods led to similar apolar/Lifshitz components. All the calculation methods were in good agreement for the surface free energy of PVC; however, a discrepancy between the methods arose as EVA content in the blends increased. It seems that there is not yet a definite solution for the calculation of solid surface free energy. Further developments of existing models are needed in order to gain consistency when calculating this important physicochemical quantity. Copyright 1998 Academic Press.

  9. Late Pleistocene ages for the most recent volcanism and glacial-pluvial deposits at Big Pine volcanic field, California, USA, from cosmogenic 36Cl dating

    Science.gov (United States)

    Vazquez, Jorge A.; Woolford, Jeff M

    2015-01-01

    The Big Pine volcanic field is one of several Quaternary volcanic fields that poses a potential volcanic hazard along the tectonically active Owens Valley of east-central California, and whose lavas are interbedded with deposits from Pleistocene glaciations in the Sierra Nevada Range. Previous geochronology indicates an ∼1.2 Ma history of volcanism, but the eruption ages and distribution of volcanic products associated with the most-recent eruptions have been poorly resolved. To delimit the timing and products of the youngest volcanism, we combine field mapping and cosmogenic 36Cl dating of basaltic lava flows in the area where lavas with youthful morphology and well-preserved flow structures are concentrated. Field mapping and petrology reveal approximately 15 vents and 6 principal flow units with variable geochemical composition and mineralogy. Cosmogenic 36Cl exposure ages for lava flow units from the top, middle, and bottom of the volcanic stratigraphy indicate eruptions at ∼17, 27, and 40 ka, revealing several different and previously unrecognized episodes of late Pleistocene volcanism. Olivine to plagioclase-pyroxene phyric basalt erupted from several vents during the most recent episode of volcanism at ∼17 ka, and produced a lava flow field covering ∼35 km2. The late Pleistocene 36Cl exposure ages indicate that moraine and pluvial shoreline deposits that overlie or modify the youngest Big Pine lavas reflect Tioga stage glaciation in the Sierra Nevada and the shore of paleo-Owens Lake during the last glacial cycle.

    Ports are complex environments due to their complicated geometry (quays, channels, and piers), the presence of human activities (vessel traffic, yards, industries, and discharges), and natural factors (stream and torrent inputs, sea action, and currents). Due to the many activities that take place in a port, sediments and waters are often contaminated by different kinds of chemicals, such as hydrocarbons, dioxins, pesticides, nutrients, and metals. The contamination rate of a port basin is site specific and depends on the sources of contamination in the nearby urban system as well as the port system itself, such as city discharges and sewers, river intake, vessel traffic, factories (Taylor and Owens, 2009). Moreover, two important sources and vehicles of contaminants are: a) anthropogenic road deposited sediments derived from the runoff of the port and city area, and natural road deposited sediments derived from rivers and torrents, and b) airborne particulate matter and sediments (Taylor and Owens, 2009). The Port of Genoa is situated at the apex of the Ligurian Sea in the north western Mediterranean Sea and is characterised by the presence of several commercial activities that have contributed, over the years, and still contribute today, to the contaminant accumulation in both the water column and the bottom sediments. This port basin includes the mouth of several streams and the mouth of the Bisagno and the Polcevera Torrents, along the banks of which can be found several small towns, quarries, factories, and the suburbs of the city of Genoa, a ferry terminal, different container terminals, marinas, dry docks, the coal power plant of Genoa, and different wastewater treatment plant discharges. Starting from these considerations, we have examined the marine environment of a port from the point of view of the water mass circulation, hydrological characteristics, distribution of the sediment grain size, mineralogical characteristics, and metal concentrations of the

  12. Rotation of Jets from T-Tauri Stars New Clues from Hst/stis

    Science.gov (United States)

    Coffey, Deirdre; Woitas, Jens; Francesca, Bacciotti; Ray, Thomas P.; Eisloffel, Jochen

    Whether jets from newly forming stars rotate is a fundamental question in star formation research. Theoretical models propose jet rotation as a means of removing angular momentum from the young star and disk system thus allowing accretion. While widely accepted this idea has not yet been tested observational due to the high resolution requirement of examining jets close to their launching point. Previous findings from the Hubble Space Telescope Imaging Spectrograph (HST/STIS) and Owens Valley Radio Observatory (OVRO) give indications of same sense rotation of the jet (Bacciotti et al 2002) and disk (Testi et al 2002) respectively of T Tauri star DG Tau. We report preliminary findings from HST/STIS data for 3 of 8 sources in a current survey to establish conclusively whether protostellar jets rotate. The results were positive yielding evidence of radial velocity differences about the axis at the base of all three jets of up to 20-30 km/s.

  13. The politics of atmospheric sciences: "nuclear winter" and global climate change.

    2011-01-01

    This article, by exploring the individual and collective trajectories that led to the "nuclear winter" debate, examines what originally drew scientists on both sides of the controversy to this research. Stepping back from the day-to-day action and looking at the larger cultural and political context of nuclear winter reveals sometimes surprising commonalities among actors who found themselves on opposing sides, as well as differences within the apparently coherent TTAPS group (the theory's originators: Richard P. Turco, Owen Brian Toon, Thomas P. Ackerman, James B. Pollack, and Carl Sagan). This story foreshadows that of recent research on anthropogenic climate change, which was substantially shaped during this--apparently tangential--cold war debate of the 1980s about research on the global effects of nuclear weapons.

    ABSTRACT Compulsory exposure to genetically foreign maternal tissue imprints in offspring sustained tolerance to noninherited maternal antigens (NIMA). Immunological tolerance to NIMA was first described by Dr. Ray D. Owen for women genetically negative for erythrocyte rhesus (Rh) antigen with reduced sensitization from developmental Rh exposure by their mothers. Extending this analysis to HLA haplotypes has uncovered the exciting potential for therapeutically exploiting NIMA-specific tolerance naturally engrained in mammalian reproduction for improved clinical outcomes after allogeneic transplantation. Herein, we summarize emerging scientific concepts stemming from tolerance to NIMA that includes postnatal maintenance of microchimeric maternal origin cells in offspring, expanded accumulation of immune suppressive regulatory T cells with NIMA-specificity, along with teleological benefits and immunological consequences of NIMA-specific tolerance conserved across mammalian species.

    1999-01-01

    Gideon Mantell and the Discovery of Dinosaurs is a scholarly yet accessible biography--the first in a generation--of a pioneering dinosaur hunter and scholar. Gideon Mantell discovered the Iguanodon (a famous tale set right in this book) and several other dinosaur species, spent over twenty-five years restoring Iguanodon fossils, and helped establish the idea of an Age of Reptiles that ended with their extinction at the conclusion of the Mesozoic Era. He had significant interaction with such well-known figures as James Parkinson, Georges Cuvier, Charles Lyell, Roderick Murchison, Charles Darwin, and Richard Owen. Dennis Dean, a well-known scholar of geology and the Victorian era, here places Mantell's career in its cultural context, employing original research in archives throughout the world, including the previously unexamined Mantell family papers in New Zealand.

    We report for the first time a γ-ray and multiwavelength nearly periodic oscillation in an active galactic nucleus. Using the Fermi Large Area Telescope we have discovered an apparent quasi-periodicity in the γ-ray flux (E > 100 MeV) from the GeV/TeV BL Lac object PG 1553+113. The marginal significance of the 2.18 ± 0.08 year period γ-ray cycle is strengthened by correlated oscillations observed in radio and optical fluxes, through data collected in the Owens Valley Radio Observatory, Tuorla, Katzman Automatic Imaging Telescope, and Catalina Sky Survey monitoring programs and Swift-UVOT. The optical cycle appearing in ∼10 years of data has a similar period, while the 15 GHz oscillation is less regular than seen in the other bands. Further long-term multiwavelength monitoring of this blazar may discriminate among the possible explanations for this quasi-periodicity.

    We report on optical spectroscopy of 165 flat spectrum radio quasars (FSRQs) in the Fermi 1LAC sample, which have helped allow a nearly complete study of this population. Fermi FSRQs show significant evidence for non-thermal emission even in the optical; the degree depends on the {gamma}-ray hardness. They also have smaller virial estimates of hole mass than the optical quasar sample. This appears to be largely due to a preferred (axial) view of the {gamma}-ray FSRQ and non-isotropic (H/R {approx} 0.4) distribution of broad-line velocities. Even after correction for this bias, the Fermi FSRQs show higher mean Eddington ratios than the optical population. A comparison of optical spectral properties with Owens Valley Radio Observatory radio flare activity shows no strong correlation.

    Transition line data for C-13H3OH in OMC-1 were gathered with a superconducting tunnel junction receiver and a 512 channel spectrometer on a 10.4 m telescope at the Owens Valley Radio Observatory. The methanol was scanned at 236 GHz and an observational efficiency of 85 percent. The survey was carried out to complement the data base on the line frequencies of internal rotors such as methanol and thereby the resolution of the C-12/C-13 ratio toward the galactic center. The data indicated that previous emission lines attributed to CO(+) and CH3CHO are actually methanol emissions, and the associated C-12/C-13 ratio is about 30.

    Skidmore, Owings and Merrill (SOM), architects and engineers for the Haj Terminal, and the Saudi Ministry of Defense and Aviation needed to design some type of covered space that would process as many as 5,000 persons an hour and shelter up to 100,000 at a time during the annual haji pilgrimage. In this area, the temperature may reach 130 degrees Fahrenheit. The answer came from a fabric used by NASA in 1967 when they were looking for a new fabric for astronaut space suits. Owens Corning had been experimenting with an ultrafine pure glass finer yarn called Beta. The yarn was woven into a fabric, coated with Teflon and tailored for astronaut wear. SOM decided upon an open-sided, tented-roof structure with white Fiberglas fabric, coated with Teflon on both sides that reflects 75 percent of the solar radiation reaching the roof, thus helping to curb the intense heat.

    CASA Uno data from sites distributed in longitude from Australia to Europe have been used to determine orbits of the GPS satellites. The characteristics of the orbits determined from double difference phase have been evaluated through comparisons of two-week solutions with one-week solutions and by comparisons of predicted and estimated orbits. Evidence of unmodeled effects is demonstrated, particularly associated with the orbit planes that experience solar eclipse. The orbit accuracy has been assessed through the repeatability of unconstrained estimated baseline vectors ranging from 245 km to 5400 km. Both the baseline repeatability and the comparison with independent space geodetic methods give results at the level of 1-2 parts in 100,000,000. In addition, the Mojave/Owens Valley (245 km) and Kokee Park/Ft. Davis (5409 km) estimates agree with VLBI and SLR to better than 1 part in 100,000,000.

    Full Text Available Abstract Being one of the biggest fluctuations in world history, humanity had never seen an event such World War I that so completely convulsed its existing ideals. Collapsing the existing ethos, the war soon showed its potencies in art and aesthetic. It would be unimaginable that poetry stood indifferent to the massive carnage. The poets who witnessed fighting on the front lines inscribed their experiences into their literary lives and used poetry as a medium of opposing war. They shaped their works to criticize threats directed to humanity. With these pecularities, war poetry, an important move towards modern poetry, stands for a geniune disengagement from the previous naturalistic poetry and signals a change in 20th century thinking. Among war poets, Wilfred Owen is an important figure whose works juxtapose the expected and the actual circumstances of war and his best known poem Dulce Et Decorum is probable to be read as an anti-war manifesto.

    This article gives an analysis of the behavior of polarizing grids and reflecting polarizers by solving Maxwell's equations, for arbitrary angles of incidence and grid rotation, for cases where the excitation is provided by an incident plane wave or a beam of radiation. The scattering and impedance matrix representations are derived and used to solve more complicated configurations of grid assemblies. The results are also compared with data obtained in the calibration of reflecting polarizers at the Owens Valley Radio Observatory (OVRO). From this analysis, we propose a method for choosing the optimum grid parameters (wire radius and spacing). We also provide a study of the effects of two types of errors (in wire separation and radius size) that can be introduced in the fabrication of a grid.

  12. Variable Viscosity Effects on Time Dependent Magnetic Nanofluid Flow past a Stretchable Rotating Plate

    2016-01-01

    Full Text Available An attempt has been made to describe the effects of geothermal viscosity with viscous dissipation on the three dimensional time dependent boundary layer flow of magnetic nanofluids due to a stretchable rotating plate in the presence of a porous medium. The modelled governing time dependent equations are transformed a from boundary value problem to an initial value problem, and thereafter solved by a fourth order Runge-Kutta method in MATLAB with a shooting technique for the initial guess. The influences of mixed temperature, depth dependent viscosity, and the rotation strength parameter on the flow field and temperature field generated on the plate surface are investigated. The derived results show direct impact in the problems of heat transfer in high speed computer disks (Herrero et al. [1] and turbine rotor systems (Owen and Rogers [2].

  14. The Effect of Surface Properties of Biomedical Materials on Their Blood Compatibility

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    The effect of surface properties of six types of biomedical materials on their blood compatibility was investigated in this study. The surface roughness of biomaterials was determined by confocal laser scanning microscopy (CLSM). The contact angle was observed by contact angle measurement (CAM). Then the surface free energy ( SFE ) and interfacial free energy ( IFE ) were calculated by the contact angle value based on the Owens-Wendt (OW) theoretical model and Young's equation. Meanwhile, hemolytic assay was employed to evaluate the haemolysis. The experimental results showed that the greater roughness was, the greater contact angle would be; the less proportion of polar component in surface free energy (SFE) was, the lower haemolysis would be.

    We report an update on a possible gamma-ray and multiwavelength nearly periodic oscillation in an active galactic nucleus. Data from the Fermi Large Area Telescope exhibit an apparent quasi-periodicity in the gamma-ray flux (E > 100 MeV) from the GeV/TeV BL Lac object PG 1553+113. The indication of a 2.18 +/- 0.08 year period gamma-ray cycle is strengthened by correlated oscillations observed in radio and optical fluxes, through data collected in the Owens Valley Radio Observatory, Tuorla, Katzman Automatic Imaging Telescope, and Catalina Sky Survey monitoring programs and Swift-UVOT. Further long-term multiwavelength monitoring of this blazar may discriminate among the possible explanations for this quasi-periodicity.

    1994-01-01

    We have performed the most comprehensive predictions of the temperature fluctuations \\dtt in the primeval isocurvature baryon models to see whether or not the models are consistent with the recent data on the cosmic microwave background anisotropies. More specifically, we computed the \\dtt corresponding to the experimental set-up by the South-Pole and the Owens Valley experiments as well as the COBE satellite. The amplitudes of the predicted \\dtt are normalized by means of the COBE 10$^\\circ$ data. The resulting constraints on the models are presented on $n - \\Omega_b$ plane in the case of $\\lambda_0=1-\\Omega_b$ (flat models) and $\\lambda_0=0$ (open models), where $n$ is the primordial spectral index of entropy fluctuations and $\\Omega_b$ is the present baryon density parameter. Our results imply that the PIB models cannot be reconciled with the current observations for any reasonable set of cosmological parameters.

  1. Characterizing Lacustrine Sediment that Records the Matuyama/Brunhes Polarity Transition at Bishop, California

    Liddicoat, Joseph; Bergeron, Jennifer; Mailloux, Brian; Kenna, Timothy

    2013-04-01

    We are doing a study of the physical and chemical properties of exposed lacustrine sediment deposited in Pleistocene Owens Lake near Bishop, CA (37.3˚ N, 241.5˚ E) that was used in an investigation of the Matuyama/Brunhes (M/B) polarity transition (Liddicoat, 1993). The study complements one of similar lacustrine sediment that records the Mono Lake Excursion in the Mono Basin, CA (38.0˚ N, 240.8˚ E) where field strength (Coe and Liddicoat, 1994) and percentage of inorganic carbon seem to be contributing factors on the ability of magnetic grains to accurately record field direction when the field is changing rapidly. For instance, there is an inverse relationship between the percentage of total inorganic carbon (TIC) and the mobility of magnetic grains that preserve the remanence - the greater the percentage of TIC, the less likely grains become realigned when the field directions change (Spokowski et al., 2011). At Bishop, as in the Mono Basin, the sediment is unweathered fine- to medium-grain sand, silt, and volcanic ash from a nearby granitic (Sierra Nevada) and volcanic provenance (Lajoie, 1968), and the dominant magnetic mineral is magnetite (Liddicoat and Coe, 1979; Liddicoat, 1993). The Bishop Ash, dated by K/Ar at about 0.68 m.y. (Dalrymple et al., 1965), is in conformable contact with the lake sediments, which are exposed in the former bank of the Owens River. At Bishop we are using samples that record reverse (Matuyama), transitional, and normal (Brunhes) polarity that were demagnetized in an alternating field. The percentage of grains with a diameter less than 63 micrometers is about 40 percent in the reversely magnetized sediment and about 65 percent in the sediment that records transitional or normal polarity. These percentages differ somewhat from those in the Mono Basin where the percentage is about 80. The percentage of total organic carbon (TOC) does not exceed about 3 percent in the Owens Lake sediment and it is slightly less in the Mono Basin

The aim of this study was to determine which of the seven selected equations used to predict basal metabolic rate most accurately estimated the measured basal metabolic rate. Methods. Twenty-eight adult women with type 2 diabetes mellitus participated in this cross-sectional study. Anthropometric and biochemical variables were measured as well as body composition (by absorptiometry dual X-ray emission and basal metabolic rate (by indirect calorimetry; basal metabolic rate was also estimated by prediction equations. Results. There was a significant difference between the measured and the estimated basal metabolic rate determined by the FAO/WHO/UNU (Pvalue<0.021 and Huang et al. (Pvalue≤0.005 equations. Conclusion. The calculations using Owen et al’s. equation were the closest to the measured basal metabolic rate.

    Levitt, J A; Weber, W H

    1977-10-01

    Luminescent greenhouse solar collectors are potentially useful for concentrating sunlight onto photovoltaic power cells. Measurements of the performance of small-scale collectors made of two commercially available materials (Owens-Illinois ED2 neodymium-doped laser glass and rhodamine 6G-doped plastic) are presented. The results are encouraging, but they indicate a need for further spectral sensitization and for reduced matrix loss coefficient. The measurements with monochromatic illumination agree with the predictions of a mathematical model developed to take account of reemission following the absorption of luminescence. Under solar illumination, the model predicts photon flux concentrations of about 15 for optimized full-scale collectors made of the materials studied and concentrations of 110 for reasonably improved glass.

    Transition line data for C-13H3OH in OMC-1 were gathered with a superconducting tunnel junction receiver and a 512 channel spectrometer on a 10.4 m telescope at the Owens Valley Radio Observatory. The methanol was scanned at 236 GHz and an observational efficiency of 85 percent. The survey was carried out to complement the data base on the line frequencies of internal rotors such as methanol and thereby the resolution of the C-12/C-13 ratio toward the galactic center. The data indicated that previous emission lines attributed to CO(+) and CH3CHO are actually methanol emissions, and the associated C-12/C-13 ratio is about 30.

    A large-amplitude traveling ionospheric disturbance (TID) was detected over Owens Valley, California, on May 18, 1980, by a highly sensitive very long baseline interferometry (VLBI) radio astronomy experiment. This TID is interpreted as the response of the ionosphere to a gravity wave excited in the neutral atmosphere by the explosion of Mount St. Helens that took place at 1532 UT on that day. A model, invoking the point-excitation of internal gravity waves in an isothermal atmosphere, which fits observations of the TID at several other stations, leads to identification of the features observed in the VLBI data. Small-amplitude higher-frequency changes in the ionosphere were detected for several hours after the passage of the large-amplitude Mount St. Helens TID, but it is not clear whether these were excited by the passage of the gravity wave or were background fluctuations.

  8. High-spatial-resolution microwave and related observations as diagnostics of coronal loops

    Holman, Gordon D.

    1986-01-01

    High spatial resolution microwave observations of coronal loops, together with theoretical models for the loop emission, can provide detailed information about the temperature, density, and magnetic field within the loop, as well as the environment around the loop. The capability for studying magnetic fields is particularly important, since there is no comparable method for obtaining direct information about coronal magnetic fields. Knowledge of the magnetic field strength and structure in coronal loops is important for understanding both coronal heating and flares. With arc-second-resolution microwave observations from the Very Large Array (VLA), supplemental high-spectral-resolution microwave data from a facility such as the Owens Valley frequency-agile interferometer, and the ability to obtain second-of-arc resolution EUV aor soft X ray images, the capability already exists for obtaining much more detailed information about coronal plasma and magnetic structures than is presently available. This capability is discussed.

  9. Surface Free Energy Determination of APEX Photosensitive Glass

    William R. Gaillard

    2016-02-01

    Full Text Available Surface free energy (SFE plays an important role in microfluidic device operation. Photosensitive glasses such as APEX offer numerous advantages over traditional glasses for microfluidics, yet the SFE for APEX has not been previously reported. We calculate SFE with the Owens/Wendt geometric method by using contact angles measured with the Sessile drop technique. While the total SFE for APEX is found to be similar to traditional microstructurable glasses, the polar component is lower, which is likely attributable to composition. The SFE was modified at each stage of device fabrication, but the SFE of the stock and fully processed glass was found to be approximately the same at a value of 51 mJ·m−2. APEX exhibited inconsistent wetting behavior attributable to an inhomogeneous surface chemical composition. Means to produce more consistent wetting of photosensitive glass for microfluidic applications are discussed.

    The effect was analyzed of surface treatment by argon ions on the surface properties of tantalum pentoxide coatings deposited by reactive magnetron sputtering. The structural parameters of the as-deposited coatings were investigated by means of transmission electron microscopy, atomic force microscopy and scanning electron microscopy. X-ray diffraction profiles and X-ray photoelectron spectra were also acquired. The total surface free energy (SFE), the polar, dispersion parts and fractional polarities, were estimated by the Owens-Wendt-Rabel-Kaeble method. The adhesive and proliferative potentials of bone marrow cells were evaluated for both Ta2O5 coatings and Ta2O5 coatings deposited by simultaneous bombardment by argon ions in in vitro tests.

    Continuous, high-resolution ??18O records from cored sediments of Pyramid Lake, Nevada, indicate that oscillations in the hydrologic balance occurred, on average, about every 150 years (yr) during the past 7630 calendar years (cal yr). The records are not stationary; during the past 2740 yr, drought durations ranged from 20 to 100 yr and intervals between droughts ranged from 80 to 230 yr. Comparison of tree-ring-based reconstructions of climate change for the past 1200 yr from the Sierra Nevada and the El alpais region of northwest New Mexico indicates that severe droughts associated with Anasazi withdrawal from Chaco Canyon at 820 cal yr BP (calendar years before present) and final abandonment of Chaco Canyon, Mesa Verde, and the Kayenta area at 650 cal yr BP may have impacted much of the western United States.During the middle Holocene (informally defined in this paper as extending from 8000 to 3000 cal yr BP), magnetic susceptibility values of sediments deposited in Pyramid Lake's deep basin were much larger than late-Holocene (3000-0 cal yr BP) values, indicating the presence of a shallow lake. In addition, the mean ?? 18O value of CaCO3 precipitated between 6500 and 3430 cal yr BP was 1.6??? less than the mean value of CaCO3 precipitated after 2740 cal yr BP. Numerical calculations indicate that the shift in the ??18O baseline probably resulted from a transition to a wetter (> 30%) and cooler (3-5??C) climate. The existence of a relatively dry and warm middle-Holocene climate in the Truckee River - Pyramid Lake system is generally consistent with archeological, sedimentological, chemical, physical, and biological records from various sites within the Great Basin of the western United States. Two high-resolution Holocene-climate records are now available from the Pyramid and Owens lake basins which suggest that the Holocene was characterized by five climatic intervals. TIC and ??18O records from Owens Lake indicate that the first interval in the early Holocene

    CASA Uno data from sites distributed in longitude from Australia to Europe have been used to determine orbits of the GPS satellites. The characteristics of the orbits determined from double difference phase have been evaluated through comparisons of two-week solutions with one-week solutions and by comparisons of predicted and estimated orbits. Evidence of unmodeled effects is demonstrated, particularly associated with the orbit planes that experience solar eclipse. The orbit accuracy has been assessed through the repeatability of unconstrained estimated baseline vectors ranging from 245 km to 5400 km. Both the baseline repeatability and the comparison with independent space geodetic methods give results at the level of 1-2 parts in 100,000,000. In addition, the Mojave/Owens Valley (245 km) and Kokee Park/Ft. Davis (5409 km) estimates agree with VLBI and SLR to better than 1 part in 100,000,000.

  15. Remapping the Constellation of Walter Benjamin’s Allegorical Method

    Directory of Open Access Journals (Sweden)

    Wong Jack

    2015-12-01

    Full Text Available The now-longstanding academic revival of allegory, as well as its import as a perennial buzzword of contemporary art criticism, owes much to a group of essays published in the journal October in the early 1980s. Authors Craig Owens and Benjamin Buchloh, in turn, drew a bloodline to the ideas of allegory that occupied Walter Benjamin throughout his literary career. However, whereas Benjamin saw allegory as the expression of a radical, indeed messianic, view of political possibility, the October writers found in allegory a counter-paradigm against Modernism that would resist the latter's totalizing tendencies by pursing its own deconstructive fate of “lack of transcendence.” In the following essay, I trace the source of this discrepancy to the crucial theological underpinnings of Benjamin's concept of allegory, without which the allegorical forms - appropriation and montage - produce not miraculous flashes of unmediated recognition but the permanent impossibility of communication.

  16. Luminescent solar concentrator development: Final subcontract report, 1 June 1982-31 December 1984

    Energy Technology Data Exchange (ETDEWEB)

    Friedman, P.S.; Parent, C.R.

    1987-04-01

    An investigation of luminescent solar concentrators (LSCs) was begun by the US Department of Energy (DOE) at Owens-Illinois, Inc., in 1978. Experimental and theoretical results of that investigation are summarized in this report. An assessment of the LSC technology was compiled to provide a concise description to guide future research in this field. Since 1978, tremendous progress was made in the development of this device as a practical nonimaging concentrator for achieving solar concentration ratios on the order of 10X. The two most important technical achievements appear to be first, the understanding that dye self-absorption of radiated energy is not as serious a problem as originally thought; and second, the demonstration that organic dyes in polymeric hosts are capable of surviving outdoors in bright sunlight for years without serious degradation. System efficiencies approaching 4% have been achieved for photovoltaic conversion and theoretical efficiencies on the order of 9% appear feasible for large-area devices.

  19. Peer Instruction: Comparing Clickers to Flashcards

    CERN Document Server

    Lasry, N

    2007-01-01

    Peer Instruction (PI) is a student-centered instructional approach developed at Harvard by Eric Mazur (1997). The method has been welcomed by the science community and adopted by a large number of colleges and universities, due among other reasons to its common sense approach and its documented effectiveness. In PI, the progression of any given class depends on the outcome of real-time student feedback to ConcepTests: multiple-choice conceptual questions. In the early 1990s, students responded to ConcepTests using flashcards showing their answer. Instructors would then estimate the proportion of students holding each alternative conception. A few years later Mazur began using wireless handheld devices - colloquially called clickers- to replace the flashcards. Previous users of clickers in university classrooms had reported benefits such as increased rates of attendance and decreased rates of attrition (Owens et al., 2004; Lopez-Herrejon & Schulman, 2004). This paper empirically measures the specific contr...

    Full Text Available Consumption of foods with saturated fats has been contributed to overweight in Mexican population. Saturated fat was replaced in 50 and 100% in cooked sausages to determinate differences in texture profile analysis ad shear tests with Warner-Bratzler blade and Meullenet-Owens razor blade. In same manner, expressible moisture and oxidative rancidity were studied. Saturated fat replacement by oleogel resulted in a softer but more cohesive texture. In shear tests, fat replacement resulted in the gradually decrease of the studied parameters, related to a less hard and easy to chew texture. Oleogel as fat replacer improved water retention, probably by the celluloses in oleogel, and decreased lipids oxidative rancidity by the unsaturated lipids present in oleogel vegetable oil. Results demonstrate that fat replacement with oleogel improved textural and nutritional properties of cooked sausages.

    2017-02-01

    Trauma exposure is associated with various parenting difficulties, but few studies have examined relationships between trauma, posttraumatic stress disorder (PTSD), and parenting stress. Parenting stress is an important facet of parenting and mediates the relationship between parental trauma exposure and negative child outcomes (Owen, Thompson, & Kaslow, 2006). We examined trauma type (child maltreatment, intimate partner violence, community violence, and non-interpersonal traumas) and PTSD symptoms as predictors of parenting stress in a sample of 52 trauma-exposed mothers. Community violence exposure and PTSD symptom severity accounted for significant variance in parenting stress. Further analyses revealed that emotional numbing was the only PTSD symptom cluster accounting for variance in parenting stress scores. Results highlight the importance of addressing community violence exposure and emotion regulation difficulties with trauma-exposed mothers.

  2. Homology and the hierarchy of biological systems.

    2008-07-01

    Homology is the similarity between organisms due to common ancestry. Introduced by Richard Owen in 1843 in a paper entitled "Lectures on comparative anatomy and physiology of the invertebrate animals", the concept of homology predates Darwin's "Origin of Species" and has been very influential throughout the history of evolutionary biology. Although homology is the central concept of all comparative biology and provides a logical basis for it, the definition of the term and the criteria of its application remain controversial. Here, I will discuss homology in the context of the hierarchy of biological organization. I will provide insights gained from an exemplary case study in evolutionary developmental biology that indicates the uncoupling of homology at different levels of biological organization. I argue that continuity and hierarchy are separate but equally important issues of homology. (c) 2008 Wiley Periodicals, Inc.

    Results from the first year of the Cassini mission show that Titan has an active surface with few impact craters and abundant hints of cryovolcanism, tectonism, aeolian and fluvial activity (Porco et al., 2005; Elachi et al., 2005). Methane clouds and surface characteristics strongly imply the presence of an active global methane cycle analogous to Earth's hydrological cycle. Astrobiological interest in Titan has previously focused on possible prebiological chemical evolution on a moon with a thick nitrogen atmosphere and rich organic chemistry (Raulin and Owen, 2002). Yet the emerging new picture of Titan has raised prospects for the possibility of extant life. Several key requirements for life appear to be present, including liquid reservoirs, organic molecules and ample energy sources. One promising location may be hot springs in contact with hydrocarbon reservoirs. Hydrogenation of photochemically produced acetylene could provide metabolic energy for near-surface organisms and also replenish atmospheric methane (Schulze-Makuch and Grinspoon, 2005). The energy released could be used by organisms to drive endothermic reactions, or go into heating their surroundings, helping to create their own liquid microenvironments. In environments which are energy-rich but liquid-poor, like the near-surface of Titan, natural selection may favor organisms that use their ``waste heat" to melt their own watering holes. Downward transport of high energy photochemical compounds could provide an energy supply for near-surface organisms which could be used, in part, to maintain the liquid environments conducive to life. We will present the results of thermal modeling designed to test the feasibility of biothermal melting on Titan. C. Porco and the Cassini Imaging Team (2005) Nature 434, 159-168; C.

    Gondwana breakup since the Jurassic and the northward motion of India toward Eurasia were associated with formation of ocean basins and ophiolite obduction between and onto the Indian and Arabian margins. Here we reconcile marine geophysical data from preserved oceanic basins with the age and location of ophiolites in NW India and SE Arabia and seismic tomography of the mantle below the NW Indian Ocean. The North Somali and proto-Owen basins formed due to 160-133 Ma N-S extension between India and Somalia. Subsequent convergence destroyed part of this crust, simultaneous with the uplift of the Masirah ophiolites. Most of the preserved crust in the Owen Basin may have formed between 84 and 74 Ma, whereas the Mascarene and the Amirante basins accommodated motion between India and Madagascar/East Africa between 85 and circa 60 Ma and 75 and circa 66 Ma, respectively. Between circa 84 and 45 Ma, oblique Arabia-India convergence culminated in ophiolite obduction onto SE Arabia and NW India and formed the Carlsberg slab in the lower mantle below the NW Indian Ocean. The NNE-SSW oriented slab may explain the anomalous bathymetry in the NW Indian Ocean and may be considered a paleolongitudinal constraint for absolute plate motion. NW India-Asia collision occurred at circa 20 Ma deforming the Sulaiman ranges or at 30 Ma if the Hindu Kush slab north of the Afghan block reflects intra-Asian subduction. Our study highlights that the NW India ophiolites have no relationship with India-Asia motion or collision but result from relative India-Africa/Arabia motions instead.

  7. Effective magnetization of the dust particles in a complex plasma

    The large mass and size of the dust particles in a complex plasma has several advantages, including low characteristic frequencies on the order of a few Hz and the ability to record their motion with video cameras. However, these properties pose major difficulties for achieving strong magnetization. While the light electrons and ions can be magnetized by (superconducting) magnets, magnetizing the heavy dust component is extremely challenging. Instead of further increasing the magnetic field strengths or decreasing the particle size, we use the analogy between the Lorentz force and the Coriolis force experienced by particles in a rotating reference frame to create ``effective magnetic fields'' which is a well-established technique in the field of trapped quantum gases [1]. To induce rotation in a complex plasma, we take advantage of the neutral drag force, which allows to transmit the motion of a rotating neutral gas to the dust particles [2]. The equations of motion in the rotating frame agree with those in a stationary gas except for the additional centrifugal and Coriolis forces [3]. Due to the slow rotation frequencies (˜ Hz) and contrary to the situation in a strong magnetic field, only the properties of the heavy dust particles are notably affected. Experiments with a rotating electrode realize the desired velocity profile for the neutral gas and allow us to verify the efficiency of the concept [3].[4pt] This work was performed in collaboration with J.

  8. Regulating the 1918-19 pandemic: flu, stoicism and the Northcliffe press.

    Social historians have argued that the reason the 1918–19 ‘Spanish’ influenza left so few traces in public memory is that it was ‘overshadowed’ by the First World War, hence its historiographical characterisation as the ‘forgotten’ pandemic. This paper argues that such an approach tends to overlook the crucial role played by wartime propaganda. Instead, I put emotion words, emotives and metaphors at the heart of my analysis in an attempt to understand the interplay between propaganda and biopolitical discourses that aimed to regulate civilian responses to the pandemic. Drawing on the letters of Wilfred Owen, the diaries of the cultural historian Caroline Playne and the reporting in the Northcliffe press, I argue that the stoicism exhibited by Owen and amplified in the columns of The Times and the Daily Mail is best viewed as a performance, an emotional style that reflected the politicisation of ‘dread’ in war as an emotion with the potential to undermine civilian morale. This was especially the case during the final year of the conflict when war-weariness set in, leading to the stricter policing of negative emotions. As a protean disease that could present as alternately benign and plague-like, the Spanish flu both drew on these discourses and subverted them, disrupting medical efforts to use the dread of foreign pathogens as an instrument of biopower. The result was that, as dread increasingly became attached to influenza, it destabilised medical attempts to regulate the civilian response to the pandemic, undermining Owen’s and the Northcliffe press’s emotives of stoicism.

    This study involved analyses of kerogen petrography, gas desorption, geochemistry, microporosity, and mesoporosity of the New Albany Shale (Devonian-Mississippian) in the eastern part of the Illinois Basin. Specifically, detailed core analysis from two locations, one in Owen County, Indiana, and one in Pike County, Indiana, has been conducted. The gas content in the locations studied was primarily dependent on total organic carbon content and the micropore volume of the shales. Gas origin was assessed using stable isotope geochemistry. Measured and modeled vitrinite reflectance values were compared. Depth of burial and formation water salinity dictated different dominant origins of the gas in place in the two locations studied in detail. The shallower Owen County location (415-433 m [1362-1421 ft] deep) contained significant additions of microbial methane, whereas the Pike County location (832-860 m [2730-2822 ft] deep) was characterized exclusively by thermogenic gas. Despite differences in the gas origin, the total gas in both locations was similar, reaching up to 2.1 cm3/g (66 scf/ton). Lower thermogenic gas content in the shallower location (lower maturity and higher loss of gas related to uplift and leakage via relaxed fractures) was compensated for by the additional generation of microbial methane, which was stimulated by an influx of glacial melt water, inducing brine dilution and microbial inoculation. The characteristics of the shale of the Maquoketa Group (Ordovician) in the Pike County location are briefly discussed to provide a comparison to the New Albany Shale. Copyright ??2010.

    1986-12-01

    The chemical equilibrium model of HARVIEet al. (1984) has been extended to include borate species. The model is based upon the semi-empirical equations of PITZER (1973) and coworkers and is valid to high ionic strength (≈14 m) and high borate concentration. Excellent agreement with the existing emf, isopiestic and solubility data in the system (Na-K-Ca-Mg-H-Cl-SO4-CO2-B(OH)4-H2O) is obtained. Calculated mineral solubilities are in general within 10% of their experimental values, even at high ionic strengths. The model was applied to the multicomponent, high ionic strength (I ~ 10) and high borate concentration (BT ~ 0.5 m) Searles Lake evaporite deposit. Utilizing the chemical composition of the interstitial brine, the model predicts equilibrium between the brine and only those minerals which are known to be in contact with the brine. These calculations clearly demonstrate the applicability of the model to high ionic strength, high borate concentration natural waters. The model was also utilized to calculate the mineral sequences which should result from evaporation of the major source of water for Searles Lake, the Owens River. The geochemical conditions necessary for the formation of the most recent mud and saline units are examined. The final results indicate that the mineral sequences found in the most recent saline unit in Searles Lake can be produced by evaporation of a water close in composition to present Owens River water, provided primary dolomite formation is delayed and back reaction between the Parting Mud and the Upper Salt is inhibited.

El proceso descrito arranca en Inglaterra con el surgimiento de las utopías de Owen y Fourier, que desembocaron en el auge de las construcciones de ciudades y viviendas obreras promovidas no sólo por utópicos, sino también por industriales cercanos al socialismo y filántropos, y hacia finales del siglo XIX por los denominados higienistas. Las escasas realizaciones llevadas a cabo naufragaron la mayoría de las veces, pero su espíritu idealista supuso el cultivo del antiindustrial, conservador y socialista movimiento inglés del Arts and Crafts.This paper tries to show the relevant role played by social housing in the origin of the contemporary architecture during the first years of beginning of this movement in the xxth century, inside the social and economic frame that formed the second industrial revolution. The described process starts in England with the emergence of Owen's and Fourier's utopias, which ended with the summit of the constructions of cities and working housings prometed notonly by Utopians, but aleo by manufacturers near to the socialism and philanthropists, and towards the ends of the xixth century by the hygienists. The few actions performed led to the failure the most of the times, but their idealistic spirit supposed the culture of the anti-manufacturer, consen/ative and socialistic English movement of the Arts and Crafts.

  12. Variable radius cartography - History and perspectives of a new discipline

    Scalera, Giancarlo

    2014-05-01

    The map that Toscanelli sent to Columbus was an unconscious application of cartography at a smaller radius than the real. The first really conscious attempts to represent the geography of Earth on globes of radius less than the current one occurred after the formulation of the concept of expanding Earth through geological time. The American chemist and geologist Richard Owen (1810-1890) in his book Key to the geology of the globe (1857) described the principles of what he himself called Anatomical Geology, with the Earth growing as a biological organism. The book contained a global paleogeographic map of the Earth that would have had a radius of about 4000 kilometers. In 1928 J.A.H. Kerkhoff (under the pseudonym Aero-dilettant) published a series of paleogeographic globes on which the modern oceans disappeared. With the same artisan methods of transfer continental outlines from a sphere to a smaller one, in 1933 O.C. Hilgenberg represented three different geological epochs, and, later, for the first time mapped paleopoles with their site-pole segments of meridian. Even today the traditional method of Hilgenberg is followed by senior researchers (Klaus Vogel, 2003) and younger geologists (James Maxlow). In England Hugh Owen applied the methods of traditional cartography to the variable radius one. His Atlas of Continental Displacement was in the 70s and 80s, for this discipline, a real milestone. While in the field of constant radius paleogeography the adherents to plate tectonics created many computer codes of automatic mapping (Bullard et al., 1965; Smith & Hallam, 1970; Scotese et al., 1979; and many others), in the variable radius field few tried to reach the same task. In 1972 in United States a first very simple attempt (but was not further developed) came from a private, R.B. Perry, followed by the still not-computerized Atlas of Owen, and both them constituted inspiration for the construction of a FORTRAN variable radius mapping code at INGV, with which it

  13. Cosmogenic Nuclide Exposure Dating of the Tiltill Rock Avalanche, Yosemite National Park

    Yosemite National Park serves as an excellent natural laboratory for studying rock falls and rock avalanches because these are the main processes modifying the nearly vertical slopes of this recently glaciated landscape. Mass wasting represents a significant hazard in the region and the database of previous rock falls and other mass wasting events in Yosemite is extensive, dating back to the mid-1800s. However, this record is too short to capture the recurrence characteristics and triggering mechanisms of the very largest events, necessitating studies of the geologic record of mass wasting. Rock falls and rock avalanches are readily dated by cosmogenic nuclide methods due to their instantaneous formation, and results can be tied to triggering events such as seismic activity (e.g. Stock et al., 2009). Here, we apply exposure dating to the Holocene Tiltill rock avalanche north of Hetch Hetchy Reservoir. The deposit comprises what appear to be two separate lobes of rock and debris, yielding a total volume of ~3.1 x 106 m3. Assuming an erosion rate of 0.0006 cm/yr and neglecting snowpack shielding, preliminary data suggest a mean exposure age of 11,000 + 600 year B.P. for both deposits, indicating that they were emplaced in a single event. The age of the Tiltill 'slide' is similar to earthquakes on the Owens Valley Fault between 10,800 + 600 and 10,200 + 200 cal year B.P. (Bacon, 2007) and the White Mountain Fault, ~10,000 cal year B.P. (Reheis, 1996; DePolo, 1989). Given that movement on the Owens Valley fault in 1872 caused a number of rock falls in Yosemite and the coincidence of ages between the Tiltill 'slide' and paleoseismic events, a large earthquake in Eastern Sierra Nevada may have triggered this event. Other trigger events are also possibilities, but only through compilation of a database of large rock avalanches can statistically significant groupings of events begin to demonstrate whether seismic triggering is a dominant process.

    2010-04-01

    Full Text Available This essay reads 'Our Mutual Friend' as Dickens’s rejoinder to Darwin’s theory of evolution by natural selection, and sees it as a novel that is profoundly shaped by the imaginative impact of Darwin’s work. However, the direct influence of 'On the Origin of Species' is not the essay’s major concern. Instead, the essay sees this novel as a response to some of the questions posed by Darwin’s work about how a natural world driven by chance and contigency, death, waste and hunger might be redeemed.   I focus on the figure of Mr Venus, the taxidermist who, I argue, is an affectionate portrait of Dickens’s friend Richard Owen. By tracing Owen’s involvement in debates over evolution and the origins of life, I show that these contemporary debates had a considerable backwash in a novel saturated with the metaphors of evolution, and centrally concerned with the nature of, and the relationship betweeen, life and death. I suggest that Mr Venus’s shop is a comic version of the Hunterian Museum, over which Owen presided, and that its portrayal encapuslates the novel’s concerns with evolution, life and death. I argue that Dickens’s response to the challenge of Darwinism is to see love as the world’s redemption, and that he uses transmuted versions of Mr Venus’s shop as a vivid metaphor for the idea that love is the redeeming spark of life.   I suggest, though, that in the post-Darwinian imaginative landscape, love could not redeem all, and that Dickens’s redeeming vision of love is finally inadequate to save all his characters. ‘What the alligator knew, ages deep in the slime’ was that love was powerless against nature -and what it didn’t know, and Dickens tried to show in this, his last completed novel, is that in spite of the ruthless rapacity of both nature and human society, love makes the world go round.

    The surface free energy is an important parameter that can be used to estimate the cohesion work (cohesive strength) of asphalt binders and the adhesion work between the asphalt binder and aggregates. In addition, the surface free energy characteristics of water may be mathematically combined with the surface free energy values of the asphalt binder and the aggregates to assess the moisture susceptibility of asphalt mixture, which is composed of graded aggregates, asphalt, and air voids. The sessile drop method was employed in this study to measure the static contact angle between several strategic highway research program (SHRP) asphalt binders and probe liquids. From these measurements, the surface free energies of the asphalt binder were estimated by the Owens-Wendt method. The surface free energy results of the sessile method for the different asphalt binders were similar to the results measured by contact angle method, giving credence to the applicability of this method for evaluating different types of asphalt binders. The cohesion work of asphalt binders, which is described by surface free energy, was in agreement with that obtained from pull-off tensile strength.%表面自由能足用来确定沥青材料自身的黏聚功(黏聚强度)以及沥青与石料之间的黏附功的重要参数.此外,沥青混合料(包括沥青、石料和空气)的水敏感性也可使用沥青与石料的表面自由能参数进行评价.笔者采用躺滴法测定了几种战略公路研究计划(SHRP)沥青与液体的静态接触角,采用Owens-Wendt法确定了沥青的表面自由能.结果表明,躺滴法得到的沥青表面自由能与由接触角得到的数值比较接近,说明可以应用躺滴法来测定沥青的表面自由能.由沥青的表面自由能表征的沥青黏聚能结果与Pull-off强度试验结果相吻合.

    Full Text Available Background: The accuracy of existing predictive equations to determine the resting energy expenditure (REE of professional weightlifters remains scarcely studied. Our study aimed at assessing the REE of male Asian Indian weightlifters with indirect calorimetry and to compare the measured REE (mREE with published equations. A new equation using potential anthropometric variables to predict REE was also evaluated. Materials and Methods: REE was measured on 30 male professional weightlifters aged between 17 and 28 years using indirect calorimetry and compared with the eight formulas predicted by Harris–Benedicts, Mifflin-St. Jeor, FAO/WHO/UNU, ICMR, Cunninghams, Owen, Katch-McArdle, and Nelson. Pearson correlation coefficient, intraclass correlation coefficient, and multiple linear regression analysis were carried out to study the agreement between the different methods, association with anthropometric variables, and to formulate a new prediction equation for this population. Results: Pearson correlation coefficients between mREE and the anthropometric variables showed positive significance with suprailiac skinfold thickness, lean body mass (LBM, waist circumference, hip circumference, bone mineral mass, and body mass. All eight predictive equations underestimated the REE of the weightlifters when compared with the mREE. The highest mean difference was 636 kcal/day (Owen, 1986 and the lowest difference was 375 kcal/day (Cunninghams, 1980. Multiple linear regression done stepwise showed that LBM was the only significant determinant of REE in this group of sportspersons. A new equation using LBM as the independent variable for calculating REE was computed. REE for weightlifters = −164.065 + 0.039 (LBM (confidence interval −1122.984, 794.854]. This new equation reduced the mean difference with mREE by 2.36 + 369.15 kcal/day (standard error = 67.40. Conclusion: The significant finding of this study was that all the prediction equations

    The conversion of large natural basins to managed watersheds for the purpose of providing water to urban centers has the effect of extending the influence of urban policy to rural areas. Consequences include the reduction of agricultural activity and the removal of water resources that would otherwise sustain or be available to reestablish disturbed native vegetation communities. Satisfying local and regional demands for water at a time when climatic variability is predicted to increase will be more difficult and may permanently alter natural ecosystems. Despite the services provided by natural communities, current water policy in arid lands does not always support sustainable management of the natural ecosystems. Furthermore, when water management does include information on vegetation conditions, the data are typically taken at a scale much smaller than the region of management. We studied Owens Valley, California at the watershed scale to determine the regional effects of water diversion and exportation to Los Angeles. Owens Valley is currently a managed watershed with extraction policy based on annual vegetation surveys and soil moisture measurements. This wealth of field data was combined with 13 years of Landsat TM data to identify the response in vegetative live cover to a six-year drought. During the drought, ground water extraction and the suspension of irrigation led to groundwater decline in many areas. Regions of groundwater decline were spatially correlated with areas exhibiting vegetative live cover losses of up to 80%. Following the drought, ground water recovered throughout most of the valley. Although live cover also subsequently increased, in many regions non-groundwater dependent exotic weeds increased in dominance relative to native species. This shift in cover type signals a potentially adverse shift in ecosystem function. In the most extreme case, abandoned agricultural fields have not been repopulated by native vegetation despite 100 years of

    Geoscientists strived to discover potential principles and patterns hidden inside ever-growing Big Data for scientific discoveries. To better achieve this objective, more capable computing resources are required to process, analyze and visualize Big Data (Ferreira et al., 2003; Li et al., 2013). Current CPU-based computing techniques cannot promptly meet the computing challenges caused by increasing amount of datasets from different domains, such as social media, earth observation, environmental sensing (Li et al., 2013). Meanwhile CPU-based computing resources structured as cluster or supercomputer is costly. In the past several years with GPU-based technology matured in both the capability and performance, GPU-based computing has emerged as a new computing paradigm. Compare to traditional computing microprocessor, the modern GPU, as a compelling alternative microprocessor, has outstanding high parallel processing capability with cost-effectiveness and efficiency(Owens et al., 2008), although it is initially designed for graphical rendering in visualization pipe. This presentation reports a distributed GPU computing framework for integrating GPU-based computing within distributed environment. Within this framework, 1) for each single computer, computing resources of both GPU-based and CPU-based can be fully utilized to improve the performance of visualizing and processing Big Data; 2) within a network environment, a variety of computers can be used to build up a virtual super computer to support CPU-based and GPU-based computing in distributed computing environment; 3) GPUs, as a specific graphic targeted device, are used to greatly improve the rendering efficiency in distributed geo-visualization, especially for 3D/4D visualization.

    Full Text Available O programa darwiniano sempre teve que enfrentar o desafio de uma plêiade de teorias alternativas que, por compartilhar um conjunto de pressupostos fundamentais, podem ser consideradas como formulações distintas de um único programa de pesquisa dirigido para o objetivo de articular aquilo que, seguindo a Richard Lewontin e a Elliot Sober, podemos caracterizar como uma explicação transformacional da evolução, alternativa à explicação de tipo variacional ou selecional proposta por Darwin. Antes de 1859, a teoria transformacional já tinha sido entrevista, de diferentes ângulos, por Lamarck, Geoffroy Saint-Hilaire e Chambers. Paradoxalmente, é somente depois da publicação de A origem das espécies que ela parece adquirir maior plausibilidade. O próprio Owen se atreve inclusive a sugeri-la; e, a partir daí, desde Spencer e Häeckel, passando pelos defensores da ortogênese, pelos neo-lamarkianos americanos, e chegando até Brian Goodwin, essa obstinada hidra epistemológica nunca cessou de se insinuar como sendo ou uma genuína alternativa ou um necessário complemento da teoria da seleção natural.The darwinian program has always had to face the challenge of a constellation of alternative theories that, for having a common set of fundamental presuppositions, they can considered, all of them, as modifications of only one research program directed to the objective of articulate what, following Richard Lewontin and Eliot Sober, we can characterize as a transformational explanation of evolution alternative to the variational or selectional explanation proposed by Darwin. Before 1859, that transformational theory had been suggested, from a diferent point of view, by Lamarck, Geoffroy Saint-Hilaire and Chambers; but, paradoxically, it is only after the publication of On the origin of the species that this theory won greater plausibility. Owen himself suggested it; and from Spencer and Häeckel, passing through the defenders of the

The characteristics ranging error is few meters for a SLR because of the atmospheric refraction delay. The theory and method of atmospheric refraction delay correction are discussed. The various models of atmospheric refraction are analyzed and compared. The atmospheric refraction delay based on different models by using GLAS's parameters is calculated. It shows that the model of Owens 375 is with great precise and simplified in most temperature and humidity conditions. The refraction delay corrections in the condition that altitude angle within 10?are calculated by using a simplified mapping function and CfA2. 2, and diffrences between them is only 0. 5 mm.

    High-grade metamorphic domes of the D’Entrecasteaux Islands (DEI) of eastern Papua New Guinea are located within continental crust at the tip of the westward propagating Woodlark spreading ridge. Multi-channel seismic data collected by the RV Maurice Ewing in 1992 was integrated with seismic data from 1974 and two wells drilled by the oil industry in 1973 to understand pattern and age of faults and clastic wedges in offshore basins surrounding the 2-2.5-km high DEI. The WNW-trending line of the DEI demarcates two areas of contrasting deformational and depositional histories. In the area of the Kiribisi and Trobriand basins north of the DEI, normal faults occupy a WNW-striking basin that began to rift in the early Miocene and continued to rift sporadically until the early Pliocene when all normal faults were buried by ~650 m of undeformed Plio-Pleistocene sediments. We infer that these basins formed as sub-basins within a larger forearc basin bounded to the north by the forearc high of the Trobriand Islands and to the south by the DEI. Uplift of the forearc high and inversion of normal faults near the high during the Pleistocene and suggests the possibility of present-day, southward subduction along the Trobriand trench. To the south of the DEI in the Goodenough basin, the Pleistocene section is thicker and deformed by active, WNW-striking normal faults with seafloor scarps and high-angle dips. Wedging of the Pleistocene clastic fill in a half-graben geometry along the Owen-Stanley fault in the Southern part of the Goodenough basin along the southern coastline of the bay indicates that most normal motion has now shifted to this fault system. The shift in extension from north of the DEI to the Owen-Stanley fault zone in post-Pliocene time likely signals the arrival of the propagating rift tip of the Woodlark basin. The presence of conglomerate with high-grade metamorphic clasts in the Pliocene section north of the DEI supports the idea that the uplift and erosion

    late Pleistocene and Holocene. Outcrop studies have documented the integration histories of several important drainage basins, including the Humboldt, Amargosa, Owens, and Mojave river systems, that have evolved since the Miocene within the active tectonic setting of the Great Basin; these histories have influenced lake levels in terminal basins. Many pre-late Pleistocene lakes in the western Great Basin were significantly larger and record wetter conditions than the youngest lakes. Outcrop-based lake-level data provide important checks on core-based proxy interpretations; we discuss four such comparisons. In some cases, such as for Lakes Owens and Manix, outcrop and core data synthesis yields stronger and more complete records; in other cases, such as for Bonneville and Lahontan, conflicts point toward reconsideration of confounding factors in interpretation of core-based proxies.

  3. Implications of the Nitrogen Isotope Ratio in Titan's Atmosphere for the Nitrogen Ratio in Ammonia in Comets

    2013-12-01

    The D/H ratio of water measured in solar system bodies has been established as a tool for determining the conditions under which bodies such as comets or icy moons formed. This ratio varies significantly and indicates complex thermal and chemical evolution of the solar nebula during solar system and planetary formation. Nitrogen isotope ratios also vary significantly, and in some but not all cases correlate to D/H ratios, but are poorly understood. Nitrogen in the solar nebula was primarily in the form of atomic and molecular nitrogen. The isotope ratio (14N/15N) of this reservoir is expected to be ~435 based on the ratio measured in Jupiter's atmosphere, because the atmosphere of Jupiter is made up of gas captured from the solar nebula (Owen et al., 2001). The terrestrial atmospheric ratio is 272, which is close to the ratio measured in the Earth's mantle. This may be the primordial ratio for nitrogen delivered to Earth depending on the amount of exchange between the atmosphere and the mantle and any atmospheric fractionation processes that may have influenced the ratio over time. Comets are a possible source of nitrogen in the Earth's atmosphere (Hutsmekers et al., 2009), although chondrites have also been suggested as a source (Marty, 2012). In the case of comets, nitrogen would have been essentially retained in the form of ammonia (Mousis et al., 2012), which is the most abundant form of nitrogen in comets. The nitrogen in Titan's atmosphere is expected to have originated as ammonia hydrates and converted to N2 early in Titan's history (Atreya et al., 1978). The nitrogen ratio in Titan's atmosphere is ~170, which is significantly enriched in the heavy isotope compared to the terrestrial value. We will discuss the evolution of the nitrogen ratio in Titan's atmosphere (Mandt et al., 2009), the limits of the primordial ratio in ammonia, and the implications for this ratio for the isotope ratio in ammonia in comets that should be measured by the ROSINA instrument

  6. Relevance of East African Drill Cores to Human Evolution: the Case of the Olorgesailie Drilling Project

    2016-12-01

    Drill cores reaching the local basement of the East African Rift were obtained in 2012 south of the Olorgesailie Basin, Kenya, 20 km from excavations that document key benchmarks in the origin of Homo sapiens. Sediments totaling 216 m were obtained from two drilling locations representing the past 1 million years. The cores were acquired to build a detailed environmental record spatially associated with the transition from Acheulean to Middle Stone Age technology and extensive turnover in mammalian species. The project seeks precise tests of how climate dynamics and tectonic events were linked with these transitions. Core lithology (A.K. Behrensmeyer), geochronology (A. Deino), diatoms (R.B. Owen), phytoliths (R. Kinyanjui), geochemistry (N. Rabideaux, D. Deocampo), among other indicators, show evidence of strong environmental variability in agreement with predicted high-eccentricity modulation of climate during the evolutionary transitions. Increase in hominin mobility, elaboration of symbolic behavior, and concurrent turnover in mammalian species indicating heightened adaptability to unpredictable ecosystems, point to a direct link between the evolutionary transitions and the landscape dynamics reflected in the Olorgesailie drill cores. For paleoanthropologists and Earth scientists, any link between evolutionary transitions and environmental dynamics requires robust evolutionary datasets pertinent to how selection, extinction, population divergence, and other evolutionary processes were impacted by the dynamics uncovered in drill core studies. Fossil and archeological data offer a rich source of data and of robust environment-evolution explanations that must be integrated into efforts by Earth scientists who seek to examine high-resolution climate records of human evolution. Paleoanthropological examples will illustrate the opportunities that exist for connecting evolutionary benchmarks to the data obtained from drilled African muds. Project members: R. Potts, A

    The NiCr-Cr3C2 coatings are prepared by the supersonic plasma spraying under different spraying powers and the tribological properties are studied with surface free energy theory. By measuring the contact angles of the coating, the surface free energy and its components are calculated by the Owens-Wendt geometric mean method. By comparing the analysis, it finds that the porosity, micro-hardness and friction coefficient of the coating change as the spraying power, and the trend shows a certain similarity with the polar component. The analysis result indicates that the intermolecular force of surface is affected by the temperature and velocity of the flying particles under different spraying power. That indirectly changes the surface free energy and its components. When the change happened, the tribological properties of NiCr-Cr3C2 coating will be affected directly.%利用超音速等离子喷涂技术制备了不同喷涂功率条件下的NiCr-Cr3C2涂层,结合表面自由能理论研究了其表面摩擦学性能.利用 Owens-Wendt 几何平均法计算了涂层的表面自由能及其分量.对比发现,涂层孔隙率、显微硬度和摩擦因数均随着喷涂功率的变化而变化,且其变化趋势与极性分量均表现出一定的相似性.分析表明,受喷涂功率的影响,喷涂粒子的温度和速度对涂层表面分子间作用力产生影响,从而间接改变了涂层表面的自由能,并且自由能及其分量的改变,会直接影响NiCr-Cr3C2涂层表面的摩擦学特性.

    Plasma technology has been widely used to increase the surface energy of the polymer surfaces for many industrial applications; in particular to increase in wettability. The present work was carried out to investigate how surface modification using plasma treatment modifies the surface energy of micro-injection moulded microneedles and its influence on drug delivery. Microneedles of polyether ether ketone and polycarbonate and have been manufactured using micro-injection moulding and samples from each production batch have been subsequently subjected to a range of plasma treatment. These samples were coated with bovine serum albumin to study the protein adsorption on these treated polymer surfaces. Sample surfaces structures, before and after treatment, were studied using atomic force microscope and surface energies have been obtained using contact angle measurement and calculated using the Owens-Wendt theory. Adsorption performance of bovine serum albumin and release kinetics for each sample set was assessed using a Franz diffusion cell. Results indicate that plasma treatment significantly increases the surface energy and roughness of the microneedles resulting in better adsorption and release of BSA.

    2014-01-01

    The Owens Valley Radio Observatory 40 meter telescope is currently monitoring a sample of about 1700 blazars every three days at 15 GHz, with the main scientific goal of determining the relation between the variability of blazars at radio and gamma-rays as observed with the Fermi Gamma-ray Space Telescope. The time domain relation between radio and gamma-ray emission, in particular its correlation and time lag, can help us determine the location of the high-energy emission site in blazars, a current open question in blazar research. To achieve this goal, continuous observation of a large sample of blazars in a time scale of less than a week is indispensable. Since we only look at bright targets, the time available for target observations is mostly limited by source observability, calibration requirements and slewing of the telescope. Here I describe the implementation of a practical solution to this scheduling, calibration, and slewing time minimization problem. This solution combines ideas from optimization,...

This solution combines ideas from optimization, in particular the traveling salesman problem, with astronomical and instrumental constraints. A heuristic solution using well established optimization techniques and astronomical insights particular to this situation, allow us to observe all the sources in the required three days cadence while obtaining reliable calibration of the radio flux densities. Problems of this nature will only be more common in the future and the ideas presented here can be relevant for other observing programs.

  11. On the Origins of the Quinarian System of Classification.

    2016-02-01

    William Sharp Macleay developed the quinarian system of classification in his Horæ Entomologicæ, published in two parts in 1819 and 1821. For two decades, the quinarian system was widely discussed in Britain and influenced such naturalists as Charles Darwin, Richard Owen, and Thomas Huxley. This paper offers the first detailed account of Macleay's development of the quinarian system. Macleay developed his system under the shaping influence of two pressures: (1) the insistence by followers of Linnaeus on developing artificial systems at the expense of the natural system and (2) the apparent tension between the continuity of organic nature and the failure of linear classification schemes (which continuity seemed to require). Against what he perceived as dogmatic indolence on the part of the Linnaeans, Macleay developed a philosophy of science in which hypotheses that exceeded the available evidence should be proposed and subjected to severe tests. He also developed a novel comparative anatomical methodology, the method of variation, to aid in his search for the natural system. Using this method, he developed an intricate system that showed how organic nature could be continuous without being linear. A failure to appreciate these facets of Macleay's thought has led to several misunderstandings of him and his work, most notably that he was an idealist. These misunderstandings are here rebutted.

    2012-01-01

    The simple, yet profoundly far-reaching classification scheme based on extended radio morphologies of radio galaxies, the Fanaroff-Riley classification has been a cornerstone in our understanding of radio galaxies. Over the decades since the recognition that there are two basic types of radio galaxy morphologies there have been several findings in different wavebands that have reported properties on different scales. Although it is realized that there may be intrinsic as well external causes an overarching view of how we may understand the two morphological types is missing. With the radio power-absolute magnitude relation (the Owen-Ledlow diagram) as backdrop we review and develop an understanding of the two radio galaxy types in the light of what is known about them. We have for the first time included the dust properties of the two FR classes together with the relative orientations of dust, host major axis and the radio axis to present a qualitative framework within which to understand the conditions under...

  13. On the origin of Fanaroff-Riley classification of radio galaxies: Deceleration of supersonic radio lobes

    Kawakatu, Nozomu; Nagai, Hiroshi

    2009-01-01

    We argue that the origin of "FRI/FRI{-.1em}I dichotomy" -- the division between Fanaroff-Riley class I (FRI) with subsonic lobes and class I{-.1em}I (FRI{-.1em}I) radio sources with supersonic lobes is sharp in the radio-optical luminosity plane (Owen-White diagram) -- can be explained by the deceleration of advancing radio lobes. The deceleration is caused by the growth of the effective cross-sectional area of radio lobes. We derive the condition in which an initially supersonic lobe turns into a subsonic lobe, combining the ram-pressure equilibrium between the hot spots and the ambient medium with the relation between "the hot spot radius" and "the linear size of radio sources" obtained from the radio observations. We find that the dividing line between the supersonic lobes and subsonic ones is determined by the ratio of the jet power $L_{\\rm j}$ to the number density of the ambient matter at the core radius of the host galaxy $\\bar{n}_{\\rm a}$. It is also found that there exists the maximal ratio of $(L_{\\...

    2008-01-01

    We report optical spectroscopic observations of X-shaped radio sources with the Hobby-Eberly Telescope and Multiple-Mirror Telescope, focused on the sample of candidates from the FIRST survey presented in Paper I (Cheung 2007). A total of 27 redshifts were successfully obtained, 21 of which are new, including that of a newly identified candidate source of this type which is presented here. With these observations, the sample of candidates from Paper I is over 50% spectroscopically identified. Two new broad emission-lined X-shaped radio sources are revealed, while no emission lines were detected in about one third of the observed sources; a detailed study of the line properties is deferred to a future paper. Finally, to explore their relation to the Fanaroff-Riley division, the radio luminosities and host galaxy absolute magnitudes of a spectroscopically identified sample of 50 X-shaped radio galaxies are calculated to determine their placement in the Owen-Ledlow plane.

    We argue that the origin of "FRI/FRII dichotomy"—the division between Fanaroff-Riley class I (FRI) with subsonic lobes and class II (FRII) radio sources with supersonic lobes is sharp in the radio-optical luminosity plane (Owen-White diagram)—can be explained by the deceleration of advancing radio lobes. The deceleration is caused by the growth of the effective cross-sectional area of radio lobes. We derive the condition in which an initially supersonic lobe turns into a subsonic lobe, combining the ram pressure equilibrium between the hot spots and the ambient medium with the relation between "the hot spot radius" and "the linear size of radio sources" obtained from the radio observations. We find that the dividing line between the supersonic lobes and subsonic ones is determined by the ratio of the jet power L j to the number density of the ambient matter at the core radius of the host galaxy \\bar{n}_a. It is also found that the maximal ratio of (L_j/\\bar{n}_a) exists and its value resides in (L_j/\\bar{n}_a)_max≈ 10^{44-47} erg s^{-1} cm^{3}, taking into account considerable uncertainties. This suggests that the maximal value (L_j/\\bar{n}_a)_max separates between FRIs and FRIIs.

    We compiled a sample of 24 flat-spectrum radio quasars (FSRQs), 21 BL Lacs, 13 FRI and 12 FRII radio galaxies to study the jet power and broad-line luminosity relation, and the jet power and black hole mass relation. Furthermore, we obtain the histograms of key parameters. Our main results are as the follows:(i) We found that the FSRQs are roughly separated from BL Lacs by the Ledlow-Owen FRI/FRII dividing line in the $\\rm{\\log{P_{jet}}-\\log{M}}$ plane. This result supports the unification model that BL Lacs unify with FRI radio galaxies and FSRQs unify with FRII radio galaxies.(ii)We found that the coefficient of the best-fit linear regression equation of $\\rm{\\log{L_{BLR}}-\\log{P_{jet}}}$ relation is very close to 1 for our sample. The correlation between broad line luminosity and jet power is significant which supports that jet power has a close link with accretion.

    Inactive parabolic dunes are present in southeastern Maryland, USA, along the east bank of the Potomac River. More elongate and finer-grained eolian deposits and paha-like ridges characterize the Potomac River-Patuxent River upland and the west side of Chesapeake Bay. These ridges are streamlined erosional features, veneered with eolian sediment and interspersed with dunes in the low-relief headwaters of Potomac- and Patuxent-river tributaries. Axis data for the dunes and ridges indicate formation by WNW-NW winds. Optically stimulated luminescence and radiocarbon age data suggest dune formation from ??? 33-15??ka, agreeing with the 30-13??ka ages Denny, C.S., Owens, J.P., Sirkin, L., Rubin, M., 1979. The Parsonburg Sand in the central Delmarva Peninsula, Maryland and Delaware. U.S. Geol. Surv. Prof. Pap. 1067-B, 16??pp. suggested for eolian deposits east of Chesapeake Bay. Age range and paleowind direction(s) for eolian features in the Bay region approximate those for late Wisconsin loess in the North American midcontinent. Formation of midcontinent loess and Bay-region eolian features was coeval with rapid growth of the Laurentide Ice Sheet and strong cooling episodes (??18O minima) evident in Greenland ice cores. Age and paleowind-direction coincidence, for eolian features in the midcontinent and Bay region, indicates strong mid-latitude WNW-NW winds for several hundred kilometers south of the Laurentide glacial terminus that were oblique to previously simulated anticyclonic winds for the last glacial maximum.

  19. The case for policy-relevant conservation science.

    2015-06-01

    Drawing on the "evidence-based" (Sutherland et al. 2013) versus "evidence-informed" debate (Adams & Sandbrook 2013), which has become prominent in conservation science, I argue that science can be influential if it holds a dual reference (Lentsch & Weingart 2011) that contributes to the needs of policy makers whilst maintaining technical rigor. In line with such a strategy, conservation scientists are increasingly recognizing the usefulness of constructing narratives through which to enhance the influence of their evidence (Leslie et al. 2013; Lawton & Rudd 2014). Yet telling stories alone is rarely enough to influence policy; instead, these narratives must be policy relevant. To ensure that evidence is persuasive alongside other factors in a complex policy-making process, conservation scientists could follow 2 steps: reframe within salient political contexts and engage more productively in boundary work, which is defined as the ways in which scientists "construct, negotiate, and defend the boundary between science and policy" (Owens et al. 2006:640). These will both improve the chances of evidence-informed conservation policy. © 2015 The Authors.

    Increasingly, empirical support demonstrates that the built environment may affect the physical and psychosocial well-being of patients, their families, and hospital staff (Beauchemin & Hays, 1996; Rubin, Owens, & Golden, 1998; Sherman, Varni, Ulrich, & Malcarne, 2005; Ulrich, 1991; Varni et al., 2004; Whitehouse et al., 2001). Investigators posit two mechanisms through which the built environment can impact patients: indirectly, by enhancing the quality of care and helping a patient feel more relaxed; and/or directly, by altering the physiological recovery process (Malcolm, 1992). Several literature reviews have been published on the relationship between the hospital built environment and patient outcomes (Joseph, Keller, & Kronick, 2008; Rubin et al., 1998; Sherman, Shepley, & Varni, 2005; Ulrich, Quan, Zimring, Joseph, & Choudhary, 2004). In their 1998 review, Rubin et al. found studies linking environment with a number of health and satisfaction outcomes but little research that had been conducted in a scientifically valid manner. Ulrich et al.'s 2004 review of the role of the physical environment in hospital design identified a number of more rigorously conducted studies, focusing mainly on adult environments and on issues of medical safety and hospital-acquired infection rates. Their conclusions linked environmental features such as noise to an increase in perceived stress and physiological arousal; exposure to natural light to reductions in depression, length of hospital stay, and pain medications and to improved sleep; and hospital gardens to improved physical and psychosocial functioning (Ulrich et al., 2004).

  1. Confusing dinosaurs with mammals: tetrapod phylogenetics and anatomical terminology in the world of homology.

    Science.gov (United States)

    Harris, Jerald D

    2004-12-01

    At present, three different systems of anatomical nomenclature are available to researchers describing new tetrapod taxa: a nonstandardized traditional system erected in part by Sir Richard Owen and subsequently elaborated by Alfred Romer; a standardized system created for avians, the Nomina Anatomica Avium (NAA); and a standardized system for extant (crown-group) mammals, the Nomina Anatomica Veterinaria (NAV). Conserved homologous structures widely distributed within the Tetrapoda are often granted different names in each system. The recent shift toward a phylogenetic system based on homology requires a concomitant shift toward a single nomenclatural system also based on both evolutionary and functional morphological homology. Standardized terms employed in the NAA and NAV should be perpetuated as far as possible basally in their respective phylogenies. Thus, NAA terms apply to nonavian archosaurs (or even all diapsids) and NAV terms apply to noncrown-group mammals and more basal synapsids. Taxa equally distant from both avians and crown-group mammals may maintain the traditional nonstandardized terminology until a universal anatomical nomenclature for all tetrapods is constructed.

    Polyurethane elastomers coating were synthesised by using typical diisocyanates, polyether and polyester polyols and HO-tertiary amines or diols as a chain extenders. Mole fractions of structural fragments (κexp) responsible for the polar interactions within polyurethane chains were calculated by (1)H NMR method. Obtained results were confronted with the analogous parameter values (κtheor) calculated on the basis of process stoichiometry, considering the stage of the production of isocyanate prepolymers and reaction of their extension for polyurethanes. Trials of linear correlation between the κexp parameters and surface free energy (SFE) values of investigated coatings were presented. SFE values were determined by Owens-Wendt method, using contact angles measured with the goniometric method. Based on achieved results, another empirical models, allowing for prediction the influence of the kind of polyurethane raw materials on SFE values of received coatings were determined. It was found that it is possible to regulate the SFE in the range millijoules per cubic metre by the selection of appropriate substrates. It has been found that use of 2,2,3,3-tetrafluoro-1,4-butanediol as a fluorinated extender of prepolymer chains is essential to obtain coatings with increased hydrophobicity, applied among others as biomaterials-next to diphenylmethane diisocyanate and polyoxyethylene glycol.

    Early reionization changes the pattern of anisotropies expected in the cosmic microwave backgrond. To explore these changes, we derive from first principles the equations governing anisotropies, focusing on the interactions of photons with electrons. Vishniac (1987) claimed that second-order terms can be large in a reionized universe, so we derive equations correct to second order in the perturbations. There are many more second-order terms than were considered by Vishniac. To understand the basic physics involved, we present a simple analytic approximation to the first-order equation. Then, turning to the second order equation, we show that the Vishniac term is indeed the only important one. We also present numerical results for a variety of ionization histories (in a standard cold dark matter universe) and show quantitatively how the signal in several experiments depends on the ionization history. The most pronounced indication of a reionized universe would be seen in very small scale experiments; the expected signal in the Owens Valley experiment is smaller by a factor of order 10 if the last scattering surface is at a redshift z approximately = 100 as it would be if the universe were reionized very early. On slightly larger scales, the expected signal in a reionized universe is smaller than it would be with standard recombination, but only a factor of 2 or so. The signal is even smaller in these experiments in the intermediate case where some photons last scattered at the standard recombination epoch.

    This project, ``Use of International Data Sets to Evaluate and Validate Pathway Assessment Models Applicable to Exposure and Dose Reconstruction at DOE Facilities,`` grew out of several activities being conducted by the Principal Investigator Dr. F Owen Hoffman. One activity was originally part of the Chernobyl Studies Project and began as Task 7.1D, ``Internal Dose From Direct Contamination of Terrestrial Food Sources.`` The objective of Task 7.1D was to (1) establish a collaborative US USSR effort to improve and validate our methods of forecasting doses and dose commitments from the direct contamination of food sources, and (2) perform experiments and validation studies to improve our ability to predict rapidly and accurately the long-term internal dose from the contamination of agricultural soil. The latter was to include the consideration of remedial measures to block contamination of food grown on contaminated soil. The current objective of this project is to evaluate and validate pathway-assessment models applicable to exposure and dose reconstruction at DOE facilities through use of international data sets. This project incorporates the activity of Task 7.1D into a multinational effort to evaluate data used for the prediction of radionuclide transfer through agricultural and aquatic systems to humans. It also includes participation in two multinational studies, BIOMOVS (BIOspheric MOdel Validation Study) with the Swedish National Institute for Radiation Protection and VAMP (VAlidation of Model Predictions) with the International Atomic Energy Agency, that address testing the performance of models of radionuclide transport through foodchains.

  5. Staggering successes amid controversy in California water management

    2012-12-01

    Water in California has always been important and controversial, and it probably always will be. California has a large, growing economy and population in a semi-arid climate. But California's aridity, hydrologic variability, and water controversies have not precluded considerable economic successes. The successes of California's water system have stemmed from the decentralization of water management with historically punctuated periods of more centralized strategic decision-making. Decentralized management has allowed California's water users to efficiently explore incremental solutions to water problems, ranging from early local development of water systems (such as Hetch Hetchy, Owens Valley, and numerous local irrigation projects) to more contemporary efforts at water conservation, water markets, wastewater reuse, and conjunctive use of surface and groundwater. In the cacophony of local and stakeholder interests, strategic decisions have been more difficult, and consequently occur less frequently. California state water projects and Sacramento Valley flood control are examples where decades of effort, crises, floods and droughts were needed to mobilize local interests to agree to major strategic decisions. Currently, the state is faced with making strategic environmental and water management decisions regarding its deteriorating Sacramento-San Joaquin Delta. Not surprisingly, human uncertainties and physical and fiscal non-stationarities dominate this process.

    More than 200 wells and springs were visited within a 20-mile radius of Coso Hot Springs, Calif. Hydrologic and geothermal data were collected for each well or spring site. The data includes depth, chemical quality, temperature and specific conductance of water, quantity of flow, well construction, and well logs. These data show that the normal temperature gradient in the ground is about 1.1 degrees Celsius (2 degrees Fahrenheit) per 100 feet. The temperature gradient in the thermal areas is as high as 24.4 degrees Celsius (44 degrees Fahrenheit) per 100 feet. The highest temperature measured for all the wells and springs was 142.2 degrees Celsius (288 degrees Fahrenheit). The chemical quality of water in the study area is generally good except in areas where water evaporates from land surface at Owens Valley playa or where steam escapes into the atmosphere from land surface. Computerized hydrologic and geothermal data are being stored for future use at the U.S. Geological Survey office, Laguna Niguel, Calif. (Woodard-USGS)

We defined elderly as over the age of 70.Results: The population is ageing dramatically throughout most of the world. Given that situation, clinicians are seeing and being asked to treat more elderly patients that have NSCLC. Elderly patients are less likely to participate or be allowed to participate in prospective or retrospective studies of treatments for NSCLC. Elderly patients are also less likely to be staged appropriately for their advanced tumors, and are less likely to be referred for surgery or adjuvant therapy after surgery. When treatment is tailored to patient comorbidities but not to age, the data support survival and outcomes comparable to those of younger patients.Conclusions: Data are limited on the treatment of elderly patients with NSCLC. No data exist to support limiting recommendations for treatment based on age alone. Treatments should be determined on an individual basis.Keywords: thoracic surgery, radiation therapy, chemotherapy, pulmonary, physiology, ageing, SBRT

    The fabric structure pictured is the Campus Center of La Verne College, La Verne, California. Unlike the facilities shown on the preceding pages, it is not air-supported. It is a "tension structure," its multi-coned fabric membrane supported by a network of cables attached to steel columns which function like circus tent poles. The spider-web in the accompanying photo is a computer graph of the tension pattern. The designers, Geiger-Berger Associates PC, of New York City, conducted lengthy computer analysis to determine the the best placement of columns and cables. The firm also served as structural engineering consultant on the Pontiac Silverdome and a number of other large fabric structures. Built by Birdair Structures, Inc., Buffalo, New York, the La Verne Campus Center was the first permanent facility in the United States enclosed by the space-spinoff fabric made of Owens-Corning Beta fiber glass coated with Du Pont Teflon TFE. The flexible design permits rearrangement of the interior to accommodate athletic events, student activities, theatrical productions and other recreational programs. Use of fabric covering reduced building cost 30 percent below conventional construction.

    The article presents the results of experimental research of the adhesive joints strength of graphite/epoxy composites and the results of the surface free energy of the composite surfaces. Two types of graphite/epoxy composites with different thickness were tested which are used to aircraft structure. The single-lap adhesive joints of epoxy composites were considered. Adhesive properties were described by surface free energy. Owens-Wendt method was used to determine surface free energy. The epoxy two-component adhesive was used to preparing the adhesive joints. Zwick/Roell 100 strength device were used to determination the shear strength of adhesive joints of epoxy composites. The strength test results showed that the highest value was obtained for adhesive joints of graphite-epoxy composite of smaller material thickness (0.48 mm). Statistical analysis of the results obtained, the study showed statistically significant differences between the values of the strength of the confidence level of 0.95. The statistical analysis of the results also showed that there are no statistical significant differences in average values of surface free energy (0.95 confidence level). It was noted that in each of the results the dispersion component of surface free energy was much greater than polar component of surface free energy.

    This research investigated the impact of modeling atrazine, metolachlor, and isoxaflutole/metabolite transport in artificially subsurface drained sites with temporally discrete rainfall data. Differences in considering rainfall distribution are unknown in regard to estimating agrochemical fluxes in the subsurface. The Root Zone Water Quality Model (RZWQM) simulated pesticide fate and transport at three subsurface drained sites: metolachlor/atrazine field experiment in Baton Rouge, LA (1987), and two isoxaflutole/metabolite field experiments in Allen County and Owen County, Indiana (2000). The modeling assumed linear, equilibrium sorption based on average reported physicochemical and environmental fate properties. Assumed rainfall intensity and duration influenced transport by runoff more than transport by subsurface drainage. As the importance of macropore flow increased, the necessity for using temporally discrete rainfall data became more critical. Long-term simulations indicated no significant difference between average or upper percentile (i.e., rainfall assumptions. It was necessary (i.e., within 7% of predicted loss) to use hourly or average duration storm events as opposed to daily rainfall data for total (i.e., runoff and subsurface drainage) pesticide loss over the long term.

    A "large-N" correlator that makes use of Field Programmable Gate Arrays and Graphics Processing Units has been deployed as the digital signal processing system for the Long Wavelength Array station at Owens Valley Radio Observatory (LWA-OV), to enable the Large Aperture Experiment to Detect the Dark Ages (LEDA). The system samples a ~100MHz baseband and processes signals from 512 antennas (256 dual polarization) over a ~58MHz instantaneous sub-band, achieving 16.8Tops/s and 0.236 Tbit/s throughput in a 9kW envelope and single rack footprint. The output data rate is 260MB/s for 9 second time averaging of cross-power and 1 second averaging of total-power data. At deployment, the LWA-OV correlator was the largest in production in terms of N and is the third largest in terms of complex multiply accumulations, after the Very Large Array and Atacama Large Millimeter Array. The correlator's comparatively fast development time and low cost establish a practical foundation for the scalability of a modular, heterogeneo...

  13. An Anomalous Component of Galactic Emission

    1997-01-01

    We present results from microwave background observations at the Owens Valley Radio Observatory. These observations, at 14.5 and 32 GHz, are designed to detect intrinsic anisotropy on scales of 7'. After point source removal, we detect significant emission with temperature spectral index beta ~ -2 towards the North Celestial Pole (NCP). Comparison of our data with the IRAS 100 micron map of the same fields reveals a strong correlation between this emission and the infrared dust emission. From the lack of detectable H-alpha emission, we conclude that the signals are consistent either with flat-spectrum synchrotron radiation, or with free-free emission from T_e ~ 10^6 K gas, probably associated with a large HI feature known as the NCP Loop. Assuming beta = -2.2, our data indicate a conversion T_f/I_(100 micron) = 0.075*nu(GHz)^-2.2 K/(MJy/sr). The detection of such a component suggests that we should be cautious in any assumptions made regarding foregrounds when designing experiments to map the microwave backgr...

    Full Text Available This work is the continuation of a study focused on establishing relations between surface thermodynamic properties and in vitro release mechanisms using a model drug (ampicillin trihydrate, besides analyzing the granulometric properties of new polymeric materials and thus establishing the potential to be used in the pharmaceutical field as modified delivery excipients. To do this, we used copolymeric materials derived from maleic anhydride with decreasing polarity corresponding to poly(isobutylene-alt-maleic acid (hydrophilic, sodium salt of poly(maleic acid-alt-octadecene (amphiphilic, poly(maleic anhydride-alt-octadecene (hydrophobic and the reference polymer hydroxyl-propyl-methyl-cellulose (HPMC. Each material alone and in blends underwent spectroscopic characterization by FTIR, thermal characterization by DSC and granulometric characterization using flow and compaction tests. Each tablet was prepared at different polymer ratios of 0%, 10%, 20%, 30% and 40%, and the surface properties were determined, including the roughness by micro-visualization, contact angle and water absorption rate by the sessile drop method and obtaining Wadh and surface free energy (SFE using the semi-empirical models of Young–Dupré and  Owens-Wendt-Rabel-Käelbe (OWRK, respectively. Dissolution profiles were determined simulating physiological conditions in vitro, where the kinetic models of order-zero, order-one, Higuchi and Korsmeyer–Peppas were evaluated. The results showed a strong relationship between the proportion and nature of the polymer to the surface thermodynamic properties and kinetic release mechanism.

    Plasma technology has been widely used to increase the surface energy of the polymer surfaces for many industrial applications; in particular to increase in wettability. The present work was carried out to investigate how surface modification using plasma treatment modifies the surface energy of micro-injection moulded microneedles and its influence on drug delivery. Microneedles of polyether ether ketone and polycarbonate and have been manufactured using micro-injection moulding and samples from each production batch have been subsequently subjected to a range of plasma treatment. These samples were coated with bovine serum albumin to study the protein adsorption on these treated polymer surfaces. Sample surfaces structures, before and after treatment, were studied using atomic force microscope and surface energies have been obtained using contact angle measurement and calculated using the Owens-Wendt theory. Adsorption performance of bovine serum albumin and release kinetics for each sample set was assessed using a Franz diffusion cell. Results indicate that plasma treatment significantly increases the surface energy and roughness of the microneedles resulting in better adsorption and release of BSA. PMID:26529005

    We present an analysis of the diffuse emission at 5 GHz in the first quadrant of the Galactic plane using two months of preliminary intensity data taken with the C-Band All Sky Survey (C-BASS) northern instrument at the Owens Valley Radio Observatory, California. Combining C-BASS maps with ancillary data to make temperature-temperature plots we find synchrotron spectral indices of $\\beta = -2.65 \\pm 0.05$ between 0.408 GHz and 5 GHz and $ \\beta = -2.72 \\pm 0.09$ between 1.420 GHz and 5 GHz for $-10^{\\circ} < |b| < -4^{\\circ}$, $20^{\\circ} < l < 40^{\\circ}$. Through the subtraction of a radio recombination line (RRL) free-free template we determine the synchrotron spectral index in the Galactic plane ($ |b| < 4^{\\circ}$) to be $\\beta = -2.56 \\pm 0.07$ between 0.408 GHz and 5 GHz, with a contribution of $53 \\pm 8$ per cent from free-free emission at 5\\,GHz. These results are consistent with previous low frequency measurements in the Galactic plane. By including C-BASS data in spectral fits we dem...

    Since mid-2007 we have carried out a dedicated long-term monitoring programme at 15 GHz using the Owens Valley Radio Observatory 40 meter telescope. One of the main goals of this programme is to study the relation between the radio and gamma-ray emission in blazars and to use it as a tool to locate the site of high energy emission. Using this large sample of objects we are able to characterize the radio variability, and study the significance of correlations between the radio and gamma-ray bands. We find that the radio variability of many sources can be described using a simple power law power spectral density, and that when taking into account the red-noise characteristics of the light curves, cases with significant correlation are rare. We note that while significant correlations are found in few individual objects, radio variations are most often delayed with respect to the gamma-ray variations. This suggests that the gamma-ray emission originates upstream of the radio emission. Because strong flares in mo...

METHODS: We measured REE (indirect calorimetry, body weight, height, and fat mass (FM and fat free mass (FFM, dual X-ray absorptiometry in 86 obese Caucasian premenopausal women aged 36.7±7.2 y, before and after (n = 78 women the intervention. We investigated the accuracy of ten REE predictive equations using weight, height, age, FFM and FM. RESULTS: At baseline, the most accurate equation was the Mifflin et al. (Am J Clin Nutr 1990; 51: 241-247 when using weight (bias:-0.2%, P = 0.982, 74% of accurate predictions. This level of accuracy was not reached after the diet intervention (24% accurate prediction. After the intervention, the lowest bias was found with the Owen et al. (Am J Clin Nutr 1986; 44: 1-19 equation when using weight (bias:-1.7%, P = 0.044, 81% accurate prediction, yet it provided 53% accurate predictions at baseline. CONCLUSIONS: There is a wide variation in the accuracy of REE predictive equations before and after weight loss in non-morbid obese women. The results acquire especial relevance in the context of the challenging weight regain phenomenon for the overweight/obese population.

  19. Polar poisons: did Botulism doom the Franklin expedition?

    In 1845 the Franklin expedition left London with 2 ships and 134 men on board in an attempt to find the route through the Northwest Passage. The ships were built with state-of-the-art technology for their day, but provisioned with supplies from the lowest bidder. After taking on fresh provisions in the Whalefish Islands, off the coast of Greenland, the entire crew was never heard from again. Graves found on remote Beechey Island indicate that three able-bodied seamen died during the first winter. A note written on a ship's log, later found in a cairn, indicate that the expedition's leader, Sir John Franklin, died during the second winter entrapped on the ice, by which time 24 men had also perished. The remaining crew failed in their attempt to walk out of the Arctic by an overland route. In 1981 Owen Beattie, from the University of Alberta, exhumed the remains of the sailors from the three graves on Beechey Island. Elevated lead levels were found in all three sailors. While lead poisoning has been a leading theory of the cause of the crew's deaths, blamed on the crudely tinned provisions the ships carried with them from England, chronic lead exposure may only have weakened the crew, not necessarily killed them. One of three exhumed sailors also had in his intestine the spores of an unspecified Clostridium species. The theory put forth by this article is that Botulism, type E, which is endemic in the Arctic, may have been responsible for their deaths.

    The question of exactly which lunar features persuaded Galileo that there were mountains on the moon has not yet been definitively answered; Galileo was famously more interested in the concepts rather than the topographic mapping in his drawings and the eventual engravings. Since the pioneering work of Ewen Whitaker on trying to identify which specific lunar-terminator features were those that Galileo identified as mountains on the moon in his 1609 observations reported in his Sidereus Nuncius (Venice, 1610), and since the important work on the sequence of Galileo's observations by Owen Gingerich (see "The Mystery of the Missing 2" in Galilaeana IX, 2010, in which he concludes that "the Florentine bifolium sheet [with Galileo's watercolor images] is Galileo's source for the reworked lunar diagrams in Sidereus Nuncius"), there have been advances in lunar topographical measurements that should advance the discussion. In particular, one of us (E.T.W.) at the Scientific Visualization Studio of NASA's Goddard Space Flight Center has used laser-topography from NASA's Lunar Reconnaissance Orbiter to recreate what Galileo would have seen over a sequence of dates in late November and early December 1609, and provided animations both at native resolution and at the degraded resolution that Galileo would have observed with his telescope. The Japanese Kaguya spacecraft also provides modern laser-mapped topographical maps.

    The immunoregulatory properties of hematopoietic stem cells (HSCs) have been recognized for more than 60 years, beginning in 1945, when Owen reported that genetically disparate freemartin cattle sharing a common placenta were red blood cell chimeras. In 1953, Billingham, Brent, and Medawar demonstrated that murine neonatal chimeras prepared by infusion of donor-derived hematopoietic cells exhibited donor-specific tolerance to skin allografts. Various approaches using HSCs in organ transplantation have gradually brought closer to reality the dream of inducing donor-specific tolerance in organ transplant recipients. Several hurdles needed to be overcome, especially the risk of graft-versus-host disease (GVHD), the toxicity of ablative conditioning, and the need for close donor-recipient matching. For wide acceptance, HSC therapy must be safe and reproducible in mismatched donor-recipient combinations. Discoveries in other disciplines have often unexpectedly and synergistically contributed to progress in this area. This review presents a historic perspective of the quest for tolerance in organ transplantation, highlighting current clinical approaches.

    Full Text Available A common way to measure and stimulate narrative child development is through the retelling of a story (Owen, 2006. In Chile, retelling tasks are designed considering the structure of the verbal input, both on a lexical-syntactic and textual level, as well as setting levels of complexity among them (Pavez & Coloma, 2005. The research project FONDECYT 1130420 produced a storybook – as an input of a retelling task- emphasizing not only the verbal aspect, but also the visual narrative. Therefore, we set a double objective: to design narrative images of a story, enhancing its meaning through a visual grammar, and to observe how these elements were reflected in the oral retelling of the subjects. For this purpose, along with the Story Grammar (Glen & Stein, 1979 for the textual structure analysis, we used the Grammar of Visual Design (Kress & Van Leeuwen, 1996 as analytical tool for preparing narrative images. The story was piloted in a sample of 20 kindergarten children from a semiprivate school in the Region of Valparaiso. Their oral narratives were videotaped, transcribed and analyzed. It was noted that all narrative images were mentioned in more than 60% of the recounted version. In addition, three images were referred in 90% of the child narratives, representing key moments of the story or certain complexity of the narrative input as simultaneous actions. These results highlight the importance of the visual elements of a story for the task of child retelling.

    Cucumber plants subjected to consecutive monoculture for 9 years were found to suffer from severe Fusarium wilt disease, caused by the soil-borne fungus Fusarium oxysporum f. sp. Cucumerinum J. H. Owen. In the present study, greenhouse experiments were performed to evaluate the influence of ammonia gas fumigation on Fusarium wilt suppression, fungal abundance and fungal community composition. Results showed that ammonia gas fumigation remarkably reduced disease incidence from 80% to 27%, resulting in a four-fold increase in yield, compared to the control. Total fungal abundance declined dramatically after fumigation and reached the lowest level at day 32, at 243 times lower than the control. Moreover, fumigation significantly increased soil fungal diversity, though it also decreased considerably coinciding with cucumber growth. Fumigation also significantly altered soil fungal community composition, relative to the control. Fusarium was strongly inhibited by fumigation in both relative abundance (3.8 times lower) and targeted quantification (a decrease of 167 fold). Collectively, the application of ammonia gas fumigation to control Fusarium wilt of cucumber resulted in a re-assembly of the fungal community to resemble that of a non-disease conducive consortium. Additional strategies, such as bioorganic fertilizer application, may still be required to develop sustainable disease suppression following fumigation. PMID:28230182

    We report high angular-resolution (~1") CO J=3--2 interferometric mapping, using the Submillimeter Array (SMA), of IRAS22036+5306 (I22036), a bipolar pre-planetary nebula (PPN) with knotty jets discovered in our HST SNAPshot survey of young PPNs. In addition, we have obtained supporting lower-resolution (~10") CO and 13CO J=1-0 observations with the Owens Valley Radio Observatory (OVRO) interferometer, as well as optical long-slit echelle spectra at the Palomar Observatory. The CO J=3-2 observations show the presence of a very fast (~220 km/s), highly collimated, massive (0.03 Msun) bipolar outflow with a very large scalar momentum (about 10^{39} g cm s^{-1}), and the characteristic spatio-kinematic structure of bow-shocks at the tips of this outflow. The Halpha line shows an absorption feature blue-shifted from the systemic velocity by ~100 km/s, which most likely arises in neutral interface material between the fast outflow and the dense walls of the bipolar lobes at low latitudes. The fast outflow in I2203...

    Climate change presents clear and pressing threats to business--materials and product shortages, price volatility, legal bans or consumer backlash, and damaged transportation infrastructure, to name just a few. But there are opportunities as well. Lowitt, a consultant in the sustainability field, has developed a series of detailed checklists that will help smart managers reduce operational, regulatory, and reputational risk while finding new ways to cut costs, improve performance, enhance customer relationships, and otherwise increase competitiveness. The checklist recommendations, tested and refined through Lowitt's research into and work with firms including Coca-Cola, GE, and Owens Corning, cover four broad areas in the product life cycle: sourcing, manufacturing, distribution, and consumption. Actions range from educating and incentivizing employees to use climate change-conscious behavior to measuring and reporting key metrics to determining when alternative materials, methods, sites, or contract partners may be called for. Like any such tool, the checklists don't provide a one-size-fits-all plan. Rather, they equip executives to customize their strategies according to factors such as their goods and services, risk tolerance, customer needs, and reliance on third parties throughout the value chain.

    As an adverse event, it has been reported that anticoagulation activity of warfarin was enhanced by simultaneous intakes of glucosamine and chondroitin sulfate. However, it is unclear whether these is a causative relation. Therefore, in the present study, we evaluated whether glucosamine and chondroitin sulfate enhanced the anticoagulant action of warfarin in mice in vivo, focusing on hepatic cytochrome P450 (CYPs)-mediated mechanisms. Mice were fed a diet containing various doses of glucosamine or chondroitin sulfate (0, 0.3, 1% (w/w)) for 2 weeks, and given warfarin by gavage on the last 2 days of the treatment regimen. Doses of glucosamine and chondroitin sulfate were 443 mg/kg and 464 mg/kg in the 0.3% diet groups, and 1523 mg/kg and 1546 mg/kg in the 1% diet groups. We found that 1% glucosamine significantly shortened prothrombin time and thrombotest Owen in animals given warfarin. However, the two ingredients did not induce or inhibit hepatic CYPs, including (S)-warfarin hydroxylase. These findings suggest that glucosamine and chondroitin sulfate do not affect the anticoagulation activity of warfarin through hepatic CYP mediated-mechanisms.

    One of the first government-sponsored demands for integrated assessment to support decision making in the United States is embodied in the National Environmental Policy Act of 1969 (NEPA). Over the past 25 years, Oak Ridge National Laboratory (ORNL) has supported federal agencies` in evaluating health and environmental impacts as required by NEPA. Many of ORNL`s efforts have focused on complex, programmatic assessments that break new ground and require and integrate expertise from a wide range of technical disciplines. Examples of ORNL projects that illustrate the use of integrated assessment approaches include environmental documentation for: (1) the Department of the Army`s Chemical Stockpile Disposal Program, (2) the Federal Energy Regulatory Commission`s licensing activities related to the Owens River Basin in eastern California and along a 500-mile reach of the upper Ohio River, and (3) the Nuclear Regulatory Commission`s decision regarding restart of the undamaged reactor (Unit 1) at Three Mile Island. Our discussion of these examples illustrates successful integrated assessment approaches and identifies new challenges facing integrated assessment activities.

    Full Text Available Artificial superhydrophobic films were deposited onto a glass slide by performing layer-by-layer deposition of 3.5 bilayers of poly(allylamine hydrochloride/ poly(acrylic acid polyelectrolyte, followed by a layer of SiO2 nanoparticles of various amounts to enhance the surface roughness and a fluorosilane to reduce the surface free energy. Higher SiO2 content incorporated into the films resulted in rougher surface and higher water contact angle. The total surface free energy determined by using the Owens-Wendt equation dramatically decreased from 31.46 mJ·m-2 for the film having the relatively flat surface to only 1.16 mJ·m-2 for the film having the highest surface roughness of 60.2 ± 1.1 nm. All the films were optically transparent and had excellent adhesion based on the peel test. Indoor and accelerated weathering tests revealed good weathering stability.DOI: http://dx.doi.org/10.5755/j01.ms.22.2.12952

  12. Mountain building of solid quark stars

    CERN Document Server

    2011-01-01

    One of the key differences between normal neutron and (bare) quark stars is relevant to the fact that the former are gravitationally bound while the latter self-confined unless their masses approach the maximum mass. This difference results in the possibility that quark stars could be very low massive whereas neutron stars cannot. Mountains could also be build on quark stars if realistic cold quark matter is in a solid state, and an alternative estimation of the mountain building is present. As spinning compact objects with non-axisymmetric mass distribution will radiate gravitational waves, the equations of states of pulsars could be constraint by the amplitude of gravitational waves being dependent on the heights of mountains. We then estimate the maximum mountains and thus quadrupole moment on solid quark stars, to be consistent with that by Owen (2005) if the breaking strain is 0.1, addressing that a solid quark star with mass < 10^{-2} Msun could be `potato-like'. We estimate the gravitational wave am...

    Traditionally psychological neurorehabilitation of neurosurgical patients is provided subject to availability of clear consciousness and minimal potential to communicate verbally. Cognitive and emotional disorders, problems in social adaptation, neurotic syndromes are normally targets in such cases. We work with patients having survived severe brain damage being in different states of consciousness: vegetative state, minimal state of consciousness, mutism, confusion, posttraumatic Korsaroff syndrom. Psychologist considers recovery of consciousness as the target besides traditional tasks. Construction of communication with patient is central part of such job, where the patient remains unable to contact verbally, yet it is impossible to consider potential aphasia. This is a non-verbal "dialogue" with patient created by psychologist with gradual development and involving other people and objects of environment. Inline with modern neuroscientific achievements demonstrating ability to recognize by patients with severe brain injury (A. Owen, S. Laureys, M. Monti, M. Coleman, A. Soddu, M. Boly and others) we base upon psychological science, on psychotherapeutic approaches containing instruments inevitable to work with patients in altered states of consciousness and creation of non-verbal communication with patient (Jung, Reich, Alexander, Lowen, Keleman, Arnold and Amy Mindell, S. Tomandl, D. Boadella, A. Längle, P. Levin etc). This article will include 15 years of experience to apply Process-oriented approach by A. Mindell to recovery of consciousness of neurosurgical patients based on work with "minimal signals" (micro moves, breath, mimic reactions etc.), principle of feedback, psychosomatic resonance, empathy.

    Parylene C surface was modified by the use of oxygen plasma treatment and characterized by microscopic and surface-sensitive techniques (E-SEM, AFM, XPS, LDI-TOF-MS, contact angle). The influence of the treatment on surface properties was investigated by calculations of surface free energy (Owens-Wendt method). Moreover, early adhesion (Culture Plate Method, Optical Microscopy Test) and biofilm formation ability (Cristal Violet Assay) on the parylene C surface was investigated. The bacteria strains which are common causative agents of medical device-associated infections (Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa--reference strains and clinical isolates) were used. It was concluded that chemical (oxygen insertion) and physical (nanotopography generation) changes, have a significant impact on the biocompatibility in terms of increased hydrophilicity (θ w of unmodified sample = 88° ± 2°, θ w of 60 min modified sample = 17.6° ± 0.8°) and surface free energy (SFE of unmodified sample = 42.4 mJ/m(2), and for 60 min modified sample = 70.1 mJ/m(2)). At the same time, no statistical effect on biofilm production and bacteria attachment to the modified surface of any of the tested strains was observed.

    The Sample Analysis at Mars (SAM) instrument suite of the Mars Science Laboratory (MSL) Curiosity rover is equipped to analyze both martian atmospheric gases and volatiles released by pyrolysis of solid surface materials, with target measurements including chemical and isotopic composition (Mahaffy et al., 2012). To facilitate assessment of instrument performance and validation of results obtained on Mars, SAM houses a calibration cell containing CO2, Ar, N2, Xe, and several fluorinated hydrocarbon compounds (Franz et al., 2014; Mahaffy et al., 2012). This report describes the first two experiments utilizing this calibration cell on Mars and gives results from analysis of data acquired with the SAM Quadrupole Mass Spectrometer (QMS). These data support the accuracy of isotope ratios obtained with the QMS (Conrad et al., 2016; Mahaffy et al., 2013) and provide ground-truth for reassessment of analytical constants required for atmospheric measurements, which were reported in previous contributions (Franz et al., 2015, 2014). The most significant implication of the QMS data involves reinterpretation of pre-launch contamination previously believed to affect only CO abundance measurements (Franz et al., 2015) to affect N2 abundances, as well. The corresponding adjustment to the N2 calibration constant presented here brings the atmospheric volume mixing ratios for Ar and N2 retrieved by SAM into closer agreement with those reported by the Viking mission (Owen et al., 1977; Oyama and Berdahl, 1977).

All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

    Generally most plastic materials are intrinsically hydrophobic, low surface energy materials, and thus do not adhere well to other substances. Surface treatment of polymers by discharge plasmas is of great and increasing industrial application because it can uniformly modify the surface of sample without changing the material bulk properties and is environmentally friendly. The plasma processes that can be conducted under ambient pressure and temperature conditions have attracted special attention because of their easy implementation in industrial processing. Present work deals with surface modification of polycarbonate (PC) by a dielectric barrier discharge (DBD) at atmospheric pressure. The treatment was performed in a parallel plate reactor driven by a 60Hz power supply. The DBD plasmas at atmospheric pressure were generated in air and nitrogen. Material characterization was carried out by contact angle measurements, and X-ray photoelectron spectroscopy (XPS). The surface energy of the polymer surface was calculated from contact angle data by Owens-Wendt method using distilled water and diiodomethane as test liquids. The plasma-induced chemical modifications are associated with incorporation of polar oxygen and nitrogen containing groups on the polymer surface. Due to these surface modifications the DBD-treated polymers become more hydrophilic. Aging behavior of the treated samples revealed that the polymer surfaces were prone to hydrophobic recovery although they did not completely recover their original wetting properties.

    2017-05-01

    Full Text Available The beatific vision is a subject of considerable importance both in the Christian Scriptures and in the history of Christian dogmatics. In it, humans experience and see the perfect immaterial God, which represents the final end for the saints. However, this doctrine has received less attention in the contemporary theological literature, arguably, due in part to the growing trend toward materialism and the sole emphasis on bodily resurrection in Reformed eschatology. As a piece of retrieval by drawing from the Scriptures, Medieval Christianity, and Reformed Christianity, we motivate a case for the Reformed emphasis on the immaterial and intellectual aspects of human personal eschatology and offer some constructive thoughts on how to link it to the contemporary emphasis of the body. We draw a link between the soul and the body in the vision with the help of Christology as reflected in the theology of John Calvin, and, to a greater extent, the theology of both John Owen and Jonathan Edwards.

    The feasibility of sector spin coating (or combinatorial spin-coating) is demonstrated (i.e., spin coating of various samples onto one single substrate using a metal template to divide the substrate into sectors). Film thickness increases in an angular direction against the sense of rotation. In the radial direction, the film thickness is constant within 2%. A library of 8 poly(methyl methacrylate)/polystyrene-blends with varying composition was spin coated and subsequently analyzed using automated atomic force microscopy: 24 measurements could be performed within 72 min. The contact angles of a library of 16 polyoxazoline diblock copolymers were measured using one substrate with 16 spin-coated sectors. Forty-eight measurements could be performed within 50 min. On the basis of the surface energies calculated using the Owens-Wendt-Rath-Kaeble method, the library can be divided into three groups of polymers: those containing a dispersive nonyloxazoline block, those containing a polar phenyloxazoline block, and those containing neither.

    Owens, W. Brechner; Wong, Annie P. S.

    2009-03-01

    An improved method to estimate the time-varying drift of measured conductivity from autonomous CTD profiling floats has been developed. This procedure extends previous methods developed by Wong, Johnson and Owens [2003. Delayed-mode calibration of autonomous CTD profiling float salinity data by θ- S climatology. Journal of Atmospheric and Oceanic Technology, 20, 308-318] and Böhme and Send [2005. Objective analyses of hydrographic data for referencing profiling float salinities in highly variable environments. Deep-Sea Research Part II, 52, 651-664]. It uses climatological salinity interpolated to the float positions and observed θ surfaces and chooses 10 'best' levels that are within well-mixed mode waters or deep homogeneous water masses. A piece-wise linear fit is used to estimate the temporally varying multiplicative adjustment to the float potential conductivities. An objective, statistical method is used to choose the breakpoints in the float time series where there are multiple drift trends. In the previous methods these breakpoints were chosen subjectively by manually splitting the time series into separate segments over which the fits were made. Our statistical procedure reduces the subjectivity by providing an automated way for doing the piece-wise linear fit. Uncertainties in this predicted adjustment are estimated using a Monte-Carlo simulation. Examples of this new procedure as applied to two Argo floats are presented.

    We study the relation between accretion, black hole mass and jet power in AGN, by using a large group of blazars detected by the Fermi Large Area Telescope and radio galaxies. Our main results are as follows. (i) The jet power of FSRQs and FRII-HEG depends on the black hole mass, which suggests that the FSRQs and FRII-HEG are in Radiation-Pressure Dominated regime. The jet power of BL Lacs and FRI-LEG depends on the accretion, which suggests that the BL Lacs and FRI-LEG are in the Gas-Pressure Dominated regime. (ii) We find that most of FSRQs and BL Lacs have $\\rm{P_{jet}>L_{BZ}^{max}}$, which suggests that the Blandford-Znajek mechanism is insufficient to explain the jet power of these objects. (iii) The FSRQs are roughly separated from BL Lacs by the Ledlow-Owen's dividing line in the $\\rm{\\log P_{jet}-\\log M}$ plane, which supports the unified scheme of AGN. (iv) The FSRQs and BL Lacs have a clear division at $\\rm{L_{bol}/L_{Edd}\\sim0.01}$, and the distribution of Eddington ratios of BL Lacs and FSRQs exhi...

Our unprecedentedly large sample permits us to assess with high accuracy the statistical significance of the correlation, using a surrogate-data method designed to simultaneously account for common-distance bias and the effect of a limited dynamical range in the observed quantities. We find that the statistical significance of a positive correlation between the cm radio and the broad band (E>100 MeV) gamma-ray energy flux is very high for the whole AGN sample, with a probability <1e-7 for the correlation appearing by chance. Using the...

  4. ‘What better excuse for a real adventure’: History, Memory and Tourism on the Kokoda Track

    Full Text Available Rapidly growing numbers of Australian tourists visiting overseas battle sites associated with Australian military history have been met with enthusiastic academic interest by historians, yet the vast majority of studies focus on Gallipoli, rather than the Kokoda Track. Prior to 2001, few tourists had undertaken a journey along the narrow jungle pathway, which winds 96km through the Owen Stanley Ranges in Papua New Guinea. Just over a decade later, the track supports a competitive tourism industry, dominated by Australian companies, and attracts thousands of trekkers each year. This paper applies an interdisciplinary methodology to better understand the duality of locations of battlefield tourism as sites of commemoration and, unavoidably, sites of commerce. A survey of 107 trekkers suggests that, in addition to an expression of national identity, the mythology associated with the Kokoda Track has been appropriated by Australian tourists to represent individualistic goals of personal development and transformation: meanings that originate from the site’s history but extend beyond it.

    We present results on multifrequency Very Long Baseline Array (VLBA) monitoring observations of the double-image gravitationally lensed blazar JVAS B0218+357. Multi-epoch observations started less than one month after the gamma-ray flare detected in 2012 by the Large Area Telescope on board Fermi, and spanned a 2-month interval. The radio light curves did not reveal any significant flux density variability, suggesting that no clear correlation between the high energy and low-energy emission is present. This behaviour was confirmed also by the long-term Owens Valley Radio Observatory monitoring data at 15 GHz. The milliarcsecond-scale resolution provided by the VLBA observations allowed us to resolve the two images of the lensed blazar, which have a core-jet structure. No significant morphological variation is found by the analysis of the multi-epoch data, suggesting that the region responsible for the gamma-ray variability is located in the core of the AGN, which is opaque up to the highest observing frequenc...

  6. The curious case of the 1960 Nobel Prize to Burnet and Medawar.

    Silverstein, Arthur M

    2016-03-01

    The 1960 Nobel Prize was awarded to Macfarlane Burnet and Peter Medawar for immunological tolerance. The Nobel Archives reveal that the two were never nominated together by anyone; Burnet had repeatedly been nominated for his virology studies, and the Medawar group (including Rupert Billingham and Leslie Brent) had been nominated independently for their transplantation work. A review of the 1950s literature suggests that tolerance had not yet, by 1960, reached the level of acceptance and acclaim in the immunological community to appear to justify the award. Burnet probably should have received the Prize for his virus work, and perhaps also for his Clonal Selection Theory, whereas Billingham and Brent should have shared in a Prize with Medawar for transplantation. If a Prize were to be given for tolerance, most agree that Ray Owen should have shared in it, for his work on cattle chimerism. It is suggested that the 1960 Nobel Prize to Burnet and Medawar for immunological tolerance may have been given for the wrong reasons and to the wrong associates.

    Full Text Available This essay deals with the tradition of the revelation of Purgatory to St. Patrick on Station Island in Lough Derg, whose popularity is testified not only in literary texts in the various languages of Medieval Europe but also in a unique work of art in the convent of the Sisters of Saint Clair at Todi, Umbria, a town along the Via Francigena, the road of medieval pilgrimages from Canterbury to Rome. It is a fresco which represents St. Patrick’s Purgatory, attributed to Jacopo di Mino del Pellicciaio, dated 1346. In 1974, following restoration carried out by Marcello Castrichini and Leonilde Dominici, the splendid fresco came to light again. The work was completed in 1985, but is not open to the public without special permit because it is located in the old refectory of the closed area of the convent. The fresco is discussed in some detail, comparing the forms and rituals of the Irish pilgrimage, the medieval legend of Owen to the life of Filippo Benizi, the Saint portrayed among the protagonists of the painting. In order to prove the ever-lasting popularity of the legend related to the Irish Saint in the same area another monument, the so-called ‘St. Patrick’s Well’ in Orvieto, designed by Antonio da Sangallo the Younger in 1527, is briefly referred to.

    Full Text Available Objective: To assess the adequacy of predictive equations for estimation of energy expenditure (EE, compared with the EE using indirect calorimetry in a sample of Brazilian and Spanish women with excess body weight Methods: It is a cross-sectional study with 92 obese adult women [26 Brazilian -G1- and 66 Spanish - G2- (aged 20-50]. Weight and height were evaluated during fasting for the calculation of body mass index and predictive equations. EE was evaluated using the open-circuit indirect calorimetry with respiratory hood. Results: In G1 and G2, it was found that the estimates obtained by Harris-Benedict, Shofield, FAO/WHO/ ONU and Henry & Rees did not differ from EE using indirect calorimetry, which presented higher values than the equations proposed by Owen, Mifflin-St Jeor and Oxford. For G1 and G2 the predictive equation closest to the value obtained by the indirect calorimetry was the FAO/WHO/ONU (7.9% and 0.46% underestimation, respectively, followed by Harris-Benedict (8.6% and 1.5% underestimation, respectively. Conclusion: The equations proposed by FAO/WHO/ ONU, Harris-Benedict, Shofield and Henry & Rees were adequate to estimate the EE in a sample of Brazilian and Spanish women with excess body weight. The other equations underestimated the EE.

    Studies are presented of the surface parameters of various multilayer coatings, namely, TiN, CrN, (Ti, Cr)N, TiN/TiC{sub 10}N{sub 90}, TiN/TiC{sub 20}N{sub 80} deposited by means of Arc-PVD on stainless steel (1H18N9), as well as of the same coatings with an additional Al{sub 2}O{sub 3} film deposited by reactive magnetron sputtering (RMS). The surface thickness, roughness and topography are estimated. Other parameters, such as the surface free energy (SFE) and fractional polarity are determined by means of the Wu and the Owens-Wendt-Rabel-Kaelble methods. Experiments are carried out on the in vitro cell/material interaction (in a fibroblasts culture) in order to determine the materials biomedical response. The results show some correlation between the surface properties and cell adhesion. The best biological response parameters (cell number, proliferation function, morphology) are obtained in the case of coatings with the highest values of the polar part component of the SFE and the fractional polarity, such as TiN, TiN/TiC{sub 10}N{sub 90} and oxide coatings.

    Abstract Charles Davies Sherborn was geologist, indexer and bibliographer extraordinaire. He was fascinated by science from an early age and like so many Victorians, the young Sherborn was a passionate natural history collector and was obsessed with expanding his collection of land and freshwater shells. He later described himself as being a ‘thorough magpie’ and having ‘a card-index mind’, and these two traits coalesced in his monumental Index Animalium, the compilation of which occupied 43 years of his life. One of the first visitors through the doors of the Natural History Museum in South Kensington when it opened in 1881, Sherborn began work there seven years later as one of the small band of unofficial scientific workers, paid by the number of fossils he prepared. By the time of his death in 1942, Sherborn’s corner in the Museum was the first port of call for generations of scientists seeking advice, information – or an invitation to one of his famous ‘smoke and chat’ parties. In addition to his work on the Index, Sherborn is also responsible for rescuing from damp and probable destruction the huge archive of Sir Richard Owen, the great comparative anatomist and the prime mover behind the creation of the Natural History Museum, London. Without Sherborn, this invaluable resource of correspondence, manuscripts and books may well have been irretrievably ruined. PMID:26877651

  11. Atmosphere Refraction Effects in Object Locating for Optical Satellite Remote Sensing Images

    Full Text Available The collinear rigorous geometric model contains the atmosphere refraction geometric error in off-nadir observation. In order to estimate and correct the atmosphere refraction geometric error, the ISO international standard atmospheric model and Owens atmosphere refractive index algorithm are applied to calculate the index of atmosphere refraction in different latitude and altitude. The paper uses the weighted mean algorithm to reduce the eight layers ISO standard atmospheric model into a simple troposphere and stratosphere two layers spherical atmosphere. And the LOS vector track geometric algorithm is used to estimate the atmosphere refraction geometric error in different observation off-nadir angle. The results show that the atmosphere refraction will introduce about 2.5 m or 9 m geometric displacement in 30 or 45 degree off-nadir angle individual. Therefore, during geo-location processing of agile platform and extra wide high spatial resolution imagery, there is need to take into account the influence of atmosphere refraction and correct the atmosphere refraction geometric error to enhance the geo-location precision without GCPs.

    Lake Ontario’s offshore benthic fish community includes primarily slimy sculpin, lake whitefish, rainbow smelt, lake trout, burbot, and sea lamprey. Of these, lake trout have been the focus of an international restoration effort for more than three decades (Elrod et al. 1995; Lantry and Lantry 2008). The deepwater sculpin and three species of deepwater ciscoes (Coregonus spp.) that were historically important in the offshore benthic zone became rare or were extirpated by the 1960s (Christie 1973; Owens et al. 2003; Lantry et al. 2007b; Roth et al. 2013). Ecosystem changes continue to influence the offshore benthic fish community, including the effects of dreissenid mussels, the near disappearance of burrowing amphipods (Diporeia spp.) (Dermott et al. 2005; Watkins et al. 2007), and the increased abundance and expanded geographic distribution of round goby (see Nearshore Fish Community chapter) (Lantry et al. 2007b). The fish-community objectives for the offshore benthic fish community, as described by Stewart et al. (1999), are:

    Full Text Available The semantic richness dimension referred to as body-object interaction (BOI measures perceptions of the ease with which people can physically interact with words’ referents. Previous studies have shown facilitated lexical and semantic processing for words rated high in BOI (e.g., belt than for words rated low in BOI (e.g., sun (e.g., Siakaluk, Pexman, Sears, Wilson, Locheed, & Owen, 2008b. These BOI effects have been taken as evidence that embodied information is relevant to word recognition. However, to date there is no evidence linking BOI manipulations to differences in the utilization of perceptual or sensorimotor areas of the brain. The current study used event-related fMRI to examine the neural correlates of BOI in a semantic categorization task (SCT. Sixteen healthy adults participated. Results showed that high BOI words were associated with activation in the left inferior parietal lobule (supramarginal gyrus, BA 40, a sensory association area involved in kinesthetic memory. These results provide evidence that the BOI dimension captures sensorimotor information, and that this contributes to semantic processing.

  14. [Development of the modern biological analogy concept in the 19th century].

    Bäumer, A

    1989-01-01

    At the beginning of the 19th century the term analogy was still synonymous with similarity, as for example in the case of Georges Cuvier. Exact criteria for determining analogy are first found in the work of Etienne Geoffroy Saint-Hilaire. Thereupon the English scientists Sharp MacLeay, William Swainson, John Obadiah Westwood and Edwin Strickland distinguished between analogy as correspondence between certain parts of the organism, i. e. only superficial resemblance, and affinity as an essential similarity in some remarkable aspects of form. Relying on these theories Richard Owen developed his theory of analogy ("a part which has the same function as another") and homology ("the same organ in different animals under every variety of form and function"). The criteria to distinguish between these two terms had to be modified and specified when the theory of evolution was developed by Charles Darwin. In the work of Thomas Henry Huxley, Ernst Haeckel and Carl Gegenbaur the modern biological term of analogy was developed, but at the same time it lost much of its importance and homology as a criterion for natural affinity became the central objective of further biological research.

    The Nampo dike, which is located at the west coast of Korea, was destroyed by wave overtopping during the storms on 30 August and 17 September in 1989. In this paper, is performed the probabilistic assessment of wave overtopping of Nampo dike by use of Owen model, Van der Meer & Janssen model and Hedges & Reis model for wave overtopping of seawall. Based on the available tidal and wave data for storm surges in 1989, the risk assessment of wave overtopping of the Nampo dike has been carried out by both Level II and Level III reliability methods. The calculated results show the general agreement of failure probability between the two methods. By utilizing the rehabilitated cross section of Nampo dike, the failure probability of wave overtopping for the Nampo dike after rehabilitation will be rapidly reduced to that of initial design at crest level of 9.0 m with the improved slope from 1:2 to 1:4 at seaside. Since the sea level may only rise 1.0 m in the next few decades, the failure probability of Nampo dike will be still in the safe range.

    Full Text Available Sonia Cerquozzi,1 Carolyn Owen2 1Department of Hematology, University of Calgary, 2Department of Hematology, Tom Baker Cancer Centre, Calgary, AB, Canada Abstract: The introduction of targeted therapy against CD20+ with the monoclonal antibody rituximab has dramatically improved the survival of B-cell non-Hodgkin lymphoma including chronic lymphocytic leukemia (CLL/small lymphocytic lymphoma. Unfortunately, CLL remains incurable with chemoimmunotherapy, with many patients having refractory or relapsing disease after rituximab-containing therapy. Obinutuzumab (GA101 is a novel humanized Type II anti-CD20 monoclonal antibody that has been investigated and compared to rituximab. Here, we provide an overview of obinutuzumab, including its mechanisms of action, preclinical data, and Phase I to III clinical studies. Preclinical data illustrate obinutuzumab's higher potency compared to rituximab through antibody-dependent cellular cytotoxicity and direct cell death. Recently, the CLL11 study presented a significant benefit from obinutuzumab chemoimmunotherapy and supports its use for treatment-naive unfit CLL patients. Herein, we review that obinutuzumab is both a safe and effective alternative to rituximab. Keywords: CLL, GA101, antibody, CD20

    The number of subjects in a pharmacokinetic two-period two-treatment crossover bioequivalence study is typically small, most often less than 60. The most common approach to testing for bioequivalence is the two one-sided tests procedure. No explicit mathematical formula for the power function in the context of the two one-sided tests procedure exists in the statistical literature, although the exact power based on Owen's special case of bivariate noncentral t-distribution has been tabulated and graphed. Several approximations have previously been published for the probability of rejection in the two one-sided tests procedure for crossover bioequivalence studies. These approximations and associated sample size formulas are reviewed in this article and compared for various parameter combinations with exact power formulas derived here, which are computed analytically as univariate integrals and which have been validated by Monte Carlo simulations. The exact formulas for power and sample size are shown to improve markedly in realistic parameter settings over the previous approximations.

    The Sample Analysis at Mars (SAM) instrument suite of the Mars Science Laboratory (MSL) Curiosity rover is equipped to analyze both martian atmospheric gases and volatiles released by pyrolysis of solid surface materials, with target measurements including chemical and isotopic composition (Mahaffy et al., 2012). To facilitate assessment of instrument performance and validation of results obtained on Mars, SAM houses a calibration cell containing CO2, Ar, N2, Xe, and several fluorinated hydrocarbon compounds (Franz et al., 2014; Mahaffy et al., 2012). This report describes the first two experiments utilizing this calibration cell on Mars and gives results from analysis of data acquired with the SAM Quadrupole Mass Spectrometer (QMS). These data support the accuracy of isotope ratios obtained with the QMS (Conrad et al., 2016; Mahaffy et al., 2013) and provide ground-truth for reassessment of analytical constants required for atmospheric measurements, which were reported in previous contributions (Franz et al., 2015, 2014). The most significant implication of the QMS data involves reinterpretation of pre-launch contamination previously believed to affect only CO abundance measurements (Franz et al., 2015) to affect N2 abundances, as well. The corresponding adjustment to the N2 calibration constant presented here brings the atmospheric volume mixing ratios for Ar and N2 retrieved by SAM into closer agreement with those reported by the Viking mission (Owen et al., 1977; Oyama and Berdahl, 1977).

    X-ray and Sunyaev-Zel'dovich effect data can be combined to determine the distance to galaxy clusters. High-resolution X-ray data are now available from Chandra, which provides both spatial and spectral information, and Sunyaev-Zel'dovich effect data were obtained from the BIMA and Owens Valley Radio Observatory (OVRO) arrays. We introduce a Markov Chain Monte Carlo procedure for the joint analysis of X-ray and Sunyaev- Zel'dovich effect data. The advantages of this method are the high computational efficiency and the ability to measure simultaneously the probability distribution of all parameters of interest, such as the spatial and spectral properties of the cluster gas and also for derivative quantities such as the distance to the cluster. We demonstrate this technique by applying it to the Chandra X-ray data and the OVRO radio data for the galaxy cluster A611. Comparisons with traditional likelihood ratio methods reveal the robustness of the method. This method will be used in follow-up paper to determine the distances to a large sample of galaxy cluster.
