  1. Captain Lord’s uremia

    2013-01-01

    The hundredth anniversary of the worst ever civilian maritime disaster was also the fiftieth anniversary of the death of arguably its most controversial character, Captain Stanley Lord, skipper of the Californian, a “tramp” steamer that became entrapped in ice just off the Grand Banks of Newfoundland on April 14, 1912. Although Lord was faulted in two widely publicized inquiries for failing to respond to Titanic’s distress signals, there may have actually been a medical reason for his behavior because he suffered from chronic renal disease and most likely had some secondary cognitive impairment due to this disease. An assessment of Lord’s health history shows that he fractured his leg as a young man; suffered from poor eyesight, which led to his premature retirement from the sea by the age of 50; and eventually died from renal failure. Furthermore, his death certificate alludes to previous uremic episodes, perhaps encompassing the time period of the Titanic accident. Lord may have been under some pressure not to reveal his infirmity because doing so could have further jeopardized his career. The literature abounds with evidence that renal insufficiency negatively affects cognition, often years before progression to end-stage renal disease. Captain Lord’s failure to act in a crisis situation may serve as a case in point. PMID:26328096

  2. Lord Kelvin's atmospheric electricity measurements

    2013-04-01

    Lord Kelvin (William Thomson), one of the greatest Victorian scientists, made a substantial but little-recognised contribution to geophysics through his work on atmospheric electricity. He developed sensitive instrumentation for measuring the atmospheric electric field, including invention of a portable electrometer, which made mobile measurements possible for the first time. Kelvin's measurements of the atmospheric electric field in 1859, made during development of the portable electrometer, can be used to deduce the substantial levels of particulate pollution blown over the Scottish island of Arran from the industrial mainland. Kelvin was also testing the electrometer during the largest solar flare ever recorded, the "Carrington event" in the late summer of 1859. Subsequently, Lord Kelvin also developed a water dropper sensor, and employed photographic techniques for "incessant recording" of the atmospheric electric field, which led to the long series of measurements recorded at UK observatories for the remainder of the 19th and much of the 20th century. These data sets have been valuable in both studies of historical pollution and cosmic ray effects on atmospheric processes.

    2013-09-01

    Lord Kelvin (William Thomson) made important contributions to the study of atmospheric electricity during a brief but productive period from 1859-1861. By 1859 Kelvin had recognised the need for "incessant recording" of atmospheric electrical parameters, and responded by inventing both the water dropper equaliser for measuring the atmospheric potential gradient (PG), and photographic data logging. The water dropper equaliser was widely adopted internationally and is still in use today. Following theoretical considerations of electric field distortion by local topography, Kelvin developed a portable electrometer, using it to investigate the PG on the Scottish island of Arran. During these environmental measurements, Kelvin may have unwittingly detected atmospheric PG changes during solar activity in August/September 1859 associated with the "Carrington event", which is interesting in the context of his later statements that solar magnetic influence on the Earth was impossible. Kelvin's atmospheric electricity work presents an early representative study in quantitative environmental physics, through the application of mathematical principles to an environmental problem, the design and construction of bespoke instrumentation for real world measurements and recognising the limitations of the original theoretical view revealed by experimental work.

    PubMed

    Gibbons, R W

    1994-06-01

    For over eight decades of chiropractic's existence, one of the myths associated with Founder Daniel David Palmer was the unsupported and largely surreptitious allegation that his son, B.J. Palmer, was somehow respondible for his death; What became known as the Palmer "patricide controversy" involved many of the players in early chiropractic and became little more than a sordid melodrama involving rival schools, chiropractic politicians and lawyers. It involved three Iowa grand juries and lawsuits and brought out the worst passions and actions of a family that had never really understood the father or the son. This study will review the original events, the allegations by those who sought to indict B.J. Palmer for the wrongful death of his father and the ultimate disposition of the incident, which still finds credence today among some who see conspiracy theories within the evolution of chiropractic.

    The structure of the Palmer Drought Severity Index (PDSI), which is perhaps the most widely used regional index of drought, is examined. The PDSI addresses two of the most elusive properties of droughts: their intensity and their beginning and ending times. Under certain conditions, the PDSI values are very sensitive to the criteria for ending an 'established' drought and precipitation during a month can have a very large effect on the PDSI values for several previous months. -from Author

  16. New geophysical models of Palmer Deep crustal structure

    NASA Astrophysics Data System (ADS)

    Yakymchuk, M. A.; Levashov, S. P.; Korchagin, I. N.; Bachmutov, V. G.; Solovyov, V. D.

    2009-04-01

    The 2004 (9th) and 2006 (11th) Ukrainian Antarctic expeditions acquired new geoelectrical data (‘short-impulse electromagnetic field formation' - FSPEF, and ‘vertical electric-resonance sounding' - VERS) along profiles across Drake Passage and along Bransfield Strait, Antarctic Peninsula, with the aim of studying the crustal structure of these features down to depths of >30 km. The sounding on this depth in Antarctic region was the first experience of deep modification of the VERS method using. Modelling experience of deep crustal structure by geophysical data with VERS method shows that there is a possibility to investigate the fluid regime, tectonic disturbances and crush zones in basement and local places of submarine volcanic activity too. This technology also gives a possibility to efficiently divide the cross-section on separate stratigraphic subsections in the sounding site and to determine its depth with high accuracy (Levashov et al., 2003; Levashov et al., 2007). Geophysical surveys enabled to yield new data set with information about Drake Passage and Palmer Deep inner crustal structure on broad continental margin of Antarctic Peninsula. Palmer Deep is located on continental (Pacific) shelf of the Antarctic Peninsula near Anvers Island and consists of three deep basins with depths from 1200? to 1500?. These basins were part of glacial outlet during glaciation's period (Rebesco et al., 1998). Geoelectrical models of Palmer Deep crustal structure along three profiles were built on the sounding data in separate points of continental shelf. Heterogeneity of Palmer Deep earth's crust obtained from VERS data modelling testified to processes of tectonic transformations of internal shelf structures. Tectonic factor explains some conformities of the most recent glaciomarine sediments and glacial streams forming during recent shelf-wide glaciations. New information about sediment distribution and inner crustal structure has an important value for searching and prospecting the hydrocarbon deposits of Palmer Deep region. These geophysical data are of particular importance for understanding of evolution and geodynamic processes at continental margin of Antarctic Peninsula. References 1.

  4. Shore platform development around Lord Howe Island, southwest Pacific

    NASA Astrophysics Data System (ADS)

    Dickson, Mark E.

    2006-06-01

    This paper describes the morphology of near-horizontal basalt and calcarenite shore platforms around Lord Howe Island as well as the lithological and process environment in which they occur. The morphology of platforms around the island is highly varied. For instance, they occur at a wide range of elevations between low-tide level and several metres above the highest tides, and their width ranges between just a few metres to over 100 m. However, common to most platforms is that they have near-horizontal surfaces that terminate abruptly in a steep scarp at their seaward edge. Correlations indicate that the variability in platform elevation and width is attributable to variability in key parameters of erosion, such as rock resistance and shoreline water depth. Whereas wider platforms occur in rocks of lesser resistance, platform elevation is shown to increase both as rock resistance and the depth of water at the shoreline increases. Wave exposure has a significant control on platform width in some instances, but an over-arching relationship was not detected. Most platforms around the island appear to have developed over the Holocene and a conceptual model is proposed to account for the varied morphology of platforms that have developed over this period. Resistant plunging cliffs occur along about 18% of the rocky coastline of Lord Howe Island and represent the starting point for the model. Where cliffs have yielded to wave erosion platforms have been initiated at an elevation controlled predominantly by rock resistance and shoreline water depth. At Lord Howe Island narrow platforms up to about 20 m wide in exposed locations generally occur about 4 to 6 m above high tide level, and have apparently been subject to very infrequent erosion. Shore platforms about 20 to 40 m wide have generally formed in less resistant rocks, are somewhat lower at about 2 to 3 m above high tide level, and have been subject to more frequent erosion over the Holocene. Most basalt platforms around the island fall within these first two categories, but there are some instances of platforms about 50 m wide. These platforms have formed in rocks of comparatively low resistance and are relatively low in elevation occurring close to the level of high tide. An interesting feature of some of these wide platforms is that, unlike the morphology of narrower platforms, raised ramparts sometimes occur on their outer edge.

  5. Lord Byron's physician: John William Polidori on somnambulism.

    PubMed

    Finger, Stanley; Stiles, Anne

    2013-01-01

    John William Polidori (1795-1821) was the Edinburgh-trained physician hired by Lord Byron to accompany him to Switzerland, where he participated in the story-telling event proposed by Byron that led, with Polidori's help, to Mary Shelley's Frankenstein. Although those interested in English literature might also remember Polidori as the author of The Vampyre, one of the first extended works of fiction about vampires, his earlier interest in somnambulism and trance states is only beginning to be appreciated. Even more than students of Romantic literature, historians of science and medicine seem little aware of what Polidori had written about oneirodynia, a synonym for somnambulism, and how his thoughts from 1815 about such activities reflected the changing medical zeitgeist at this time. This chapter examines Polidori's medical thesis in a neuroscience context and compares what he wrote to the writings of several other physicians who were fascinated by nocturnal wanderings, their causes, their manifestations, and their possible treatments.

  6. Reconceptualizing the Archetypal Trickster in Audre Lorde's Zami: A New Spelling of My Name.

    PubMed

    Saber, Yomna

    2015-01-01

    Carl Jung categorizes the trickster as a psychological archetype and sets certain parameters for it. This article examines Audre Lorde's trickster Afrekete in Zami: A New Spelling of My Name (1982) and poses the question of how typically archetypal a Black, female, lesbian trickster can be. Lorde occupies an idiosyncratic position in the canon in terms of race, gender, and sexual orientation. She bestows new qualities on her trickster coming from the peripheries she dwells in and challenges the Jungian model. Through Afrekete's linguistic dexterity and sexual identity, Lorde transforms the trickster from being seemingly innocuous into a figure of resistance grounded in lesbian erotica. PMID:26264993

    The study examines the pathological circumstances related to Byron's death, the primary issue being malaria. Lord Byron died during the Greek War of Independence against the Ottoman Empire, in Messolonghi on 19 April 1824. Byron's medical profile consists of recurrent onsets of fever, which gave rise to the issue of malaria relapses. According to Byron's letters he reported crises of fever in Greece (1810), Malta (1811), Italy (1817-1819) and England. Evidence from Byron's autopsy, specifically the absence of hepatosplenomegaly, does not support a hypothetical diagnosis of malaria. Nonetheless, the relapsing fevers cannot be ignored and the same applies to the possibility of malaria relapse or re-infection in line with the endemic nature of the Messolonghi area. Our research on the chronologies of Byron's reported fevers found that new attacks occurred at intervals of 540 days on average. Moreover, the most outstanding feature of Plasmodium vivax and Plasmodium ovale is their ability to form dormant forms of hypnozoites in the liver which, when reactivated (110-777 days), cause true relapses of clinical disease. Of course, an ex post facto diagnosis is under debate, because the diagnosis is not clinical but microscopic. Byron's example raises alarm over a current medical problem, i.e. the diagnosis of unexplained fevers, and the need for a detailed travel or immigration history, which will include malaria in the differential diagnosis.

    Wells, Peter N T

    2007-03-01

    John William Strutt, first son of the second Baron Rayleigh, was born on November 12, 1842. He was a sickly boy, so his schooling was sporadic. Nevertheless, he graduated first in his year at Cambridge and subsequently was a Fellow of Trinity College until his marriage in 1871. His father died in 1873, and he succeeded to the title third Baron Rayleigh. He converted the stable block of his country house, Terling Place, into a laboratory. In 1879, he moved back to Cambridge as Professor of Experimental Physics, but he returned to Terling in 1884. He published The Theory of Sound in 1877/1878 and, in his lifetime, 466 scientific articles. He received the 1904 Nobel Prize in Physics for the discovery of argon and made numerous seminal contributions to scientific progress. In the field of acoustics, he studied scattering, the diffraction limit, surface waves, resonance phenomena, reciprocity, streaming, radiation force, cavitation, relaxation, and binaural perception. He received many honors, was President of the Royal Society, one of the founding members of the Order of Merit, and Chancellor of Cambridge University. He also was interested in psychical research. Lord Rayleigh died on June 30, 1919. PMID:17375827

    Understanding the processes underlying the origin of species is a fundamental goal of biology. It is widely accepted that speciation requires an interruption of gene flow between populations: ongoing gene exchange is considered a major hindrance to population divergence and, ultimately, to the evolution of new species. Where a geographic barrier to reproductive isolation is lacking, a biological mechanism for speciation is required to counterbalance the homogenizing effect of gene flow. Speciation with initially strong gene flow is thought to be extremely rare, and few convincing empirical examples have been published. However, using phylogenetic, karyological, and ecological data for the flora of a minute oceanic island (Lord Howe Island, LHI), we demonstrate that speciation with gene flow may, in fact, be frequent in some instances and could account for one in five of the endemic plant species of LHI. We present 11 potential instances of species divergence with gene flow, including an in situ radiation of five species of Coprosma (Rubiaceae, the coffee family). These results, together with the speciation of Howea palms on LHI, challenge current views on the origin of species diversity. PMID:21730151

  11. Relational operants: processes and implications: a response to Palmer's review of Relational Frame Theory.

    PubMed Central

    Hayes, Steven C; Barnes-Holmes, Dermot

    2004-01-01

    Palmer has recently criticized Relational Frame Theory (RFT) on the grounds that it has developed data in search of a principle. In this reply, we show that he has done so by attacking fundamental concepts within behavior analysis itself, including the functional nature of an operant and contingencies of reinforcement as a behavioral process. His claim that RFT appeals to new behavioral principles to explain the development of relational operants is shown to be incorrect: As with any operant, RFT appeals to a history of contacted consistencies in contingencies across multiple ex-emplars to explain them. New principles only emerge later as a logically necessary extension of such operants if they exist--a view that Palmer failed to address or appreciate. Palmer's desire to see the use of methods other than matching-to-sample is proper but already largely satisfied in the empirical literature on RFT. We show Palmer's defense of Skinner's definition of verbal behavior to be illogical and unresponsive to the empirical challenge behavior analysis faces. Palmer's alternative common sense mediational associationistic account is another in more than a century of such accounts, all of which have failed empirically. At its root, Palmer's criticism is based on a mechanistic philosophy that is hostile to a traditional functional behavior analytic approach. PMID:15540506

    The two principal aims of this study were to synthesise physical and biological information to characterise the Lord Howe Rise (LHR) region and to use recent survey collections of benthic invertebrates (mostly large benthic epifauna) to describe its biogeography at regional and sub-regional scales. The LHR region is large (1.95 million km 2), spans tropical and cool temperate latitudes (18.4 to 40.3°S), and is influenced by several ocean currents, notably the East Australian Current and the Tasman Front. Our analyses revealed that biological patterns were related to two groups of geomorphic morphotypes found in this topographically complex region: subdued bathymetric features (expansive soft sediment basins and plateaus) and raised bathymetric features (scattered seamounts, guyots, knolls, and pinnacles). Raised bathymetric features in the LHR region were more likely to support richer and more abundant epifaunal assemblages dominated by suspension feeding invertebrates on hard substrata compared to subdued features which were dominated by infauna and detritivores in soft sediments. However, this trend does not apply to all raised bathymetric features (e.g., Gifford Guyot), with variations in depth, elevation, latitude, and particularly substrata affected the composition of biological assemblages. In addition, some demersal fishes, ophiuroids, and other benthic invertebrates showed distinct north-south delineations that coincide with the influence of the Tasman Front and thermal gradients. While the lack of spatially- and temporally- replicated data in the region limits our interpretation of survey data, paleo-environmental processes and examples from other regions provide some indication of how dispersal influences migration, speciation, and endemism in the LHR region. Although our current knowledge is limited, it is hoped that this review will help inform future studies in the area, as equitable examination of biological, geological, and oceanographic characteristics will facilitate future assessments of LHR biogeography and permit the inclusion of this region in biogeographic studies with a national or global context.

  13. Chemical composition of fresh snowfalls at Palmer Station, Antarctica

    NASA Astrophysics Data System (ADS)

    DeFelice, T. P.

    A first time investigation was performed to establish a chemical baseline for snowfall at Palmer Station Antarctica (64°46'S, 64°05'W) since there was no such record. A chemical baseline for snow could be use to validate climate change studies based on ice core analyses. The snow samples contained (from high to low mass concentration) total organic carbon, chloride, inorganic carbon, sodium, sulfate, magnesium, calcium, potassium, fluoride, ammonium, and nitrate, excluding hydrogen and hydroxide. The pH of these samples ranged between 4.0-6.2. The relatively low nitrate and relatively high sulfate concentrations found in our samples are consistent with the results of other studies for this region of Antarctica. The ions and pH do not appear to favor a particular wind direction during this period. The total deposition of sulfate and flouride via snowfall between 10 January and 10 February is conservatively estimated to be 4.78 and 1.3 kg km -2, respectively.

    2005-01-01

    We are engaged in a NASA Vision Mission study, called Palmer Quest after the American Antarctic explorer Nathaniel Palmer, to assess the presence of life and evaluate the habitability of the basal domain of the Mars polar caps. We address this goal through four objectives: 1. Determine the presence of amino acids, nutrients, and geochemical heterogeneity in the ice sheet. 2. Quantify and characterize the provenance of the amino acids in Mars ice. 3. Assess the stratification of outcropped units for indications of habitable zones. 4. Determine the accumulation of ice, mineralogic material, and amino acids in Mars ice caps over the present epoch. Because of the defined scientific goal for the vision mission, the Palmer Quest focus is astrobiological; however, the results of the study make us optimistic that aggressive multi-platform in-situ missions that address a wide range of objectives, such as climate change, can be supported by variations of the approach used on this mission.

  10. Evidence for increasingly variable Palmer Drought Severity Index in the United States since 1895.

    PubMed

    2016-02-15

    Annual and summertime trends towards increasingly variable values of the Palmer Drought Severity Index (PDSI) over a sub-decadal period (five years) were investigated within the contiguous United States between 1895 and the present. For the contiguous United States as a whole, there is a significant increasing trend in the five-year running minimum-maximum ranges for the annual PDSI (aPDSI5yr(min|max, range)). During this time frame, the average aPDSI5yr(min|max, range) has increased by about one full unit, indicating a substantial increase in drought variability over short time scales across the United States. The end members of the running aPDSI5yr(min|max, range) highlight even more rapid changes in the drought index variability within the past 120years. This increasing variability in the aPDSI5yr(min|max, range) is driven primarily by changes taking place in the Pacific and Atlantic Ocean coastal climate regions, climate regions which collectively comprise one-third the area of the contiguous United States. Similar trends were found for the annual and summertime Palmer Hydrological Drought Index (PHDI), the Palmer Modified Drought Index (PMDI), and the Palmer Z Index (PZI). Overall, interannual drought patterns in the contiguous United States are becoming more extreme and difficult to predict, posing a challenge to agricultural and other water-resource related planning efforts.

  12. Uplift of Lord Howe Rise during the Late Paleogene: Constraints from Micropaleontological Proxies

    NASA Astrophysics Data System (ADS)

    Kulhanek, D. K.; Morgans, H. E.; Bache, F.; Collot, J.; Rouillard, P.; Sutherland, R.

    Lord Howe Rise is located east of Australia and northwest of New Zealand within a series of basins and ridges in the Southwest Pacific Ocean that formed during the Cretaceous breakup of Gondwana. Coring of Lord Howe Rise during Deep Sea Drilling Project (DSDP) Legs 21 and 90 recovered pelagic sediments of Late Cretaceous to Cenozoic age. Neogene sequences in the region contain few hiatuses, whereas the Paleogene interval records an Eocene/Oligocene unconformity of varying duration originally interpreted to reflect major oceanographic circulation changes resulting from the development of the Antarctic Circumpolar Current. Recent work based primarily on stratal geometries and seismic reflection facies suggests that the unconformity may be related to uplift of the rise to at or near sea level as a result of subduction processes in the New Zealand region. To test this hypothesis, we collected high-resolution samples across the unconformity at three sites cored on Lord Howe Rise (DSDP Sites 207, 208, and 592) and one site in the adjacent New Caledonia Basin (DSDP Site 206) to examine changes in paleoenvironment across the unconformity. Biostratigraphic results based on calcareous nannofossils and planktic and benthic foraminifera indicate that the hiatus is of varying duration and at one site is a distinctly different age. At Sites 206, 207, and 208, the Eocene/Oligocene boundary is missing, with sediments below the unconformity of Middle Eocene age and sediments above the unconformity of Early Oligocene (Sites 206 and 208) to Middle Miocene (Site 207) age. In contrast, Site 592 records a complete Eocene/Oligocene boundary sequence, with the hiatus spanning the late Early Oligocene to Early Miocene. Sediments below the unconformity at this site are similar in age to those deposited directly above the unconformity in the New Caledonia Basin and on northern Lord Howe Rise. Paleodepths based on benthic foraminifera assemblages suggest some shallowing across the unconformity at all sites, which is consistent with tectonic activity in the region during the late Paleogene. The New Caledonia Basin and northern Lord Howe Rise sites show ~1000 m of shallowing across the unconformity, despite being at significantly different water depths today. Southern Lord Howe Rise Site 207 records the greatest change in paleodepth, with more than 1000 m of shallowing. At Site 592, only approximately 500 m of shallowing occurred across the unconformity. These results suggest tectonic activity in the region near the Eocene/Oligocene transition, in addition to the oceanographic changes that occurred at that time.

    Greywacke, argillite, greyschist and hypabyssal igneous rocks have been obtained from an Ocean Drilling Program core on the Queensland Plateau and from xenoliths in a volcanic breccia dredged from the crest of the Lord Howe Rise. Low to intermediate detrital quartz contents, 260-240 Ma K-Ar ages, and only moderately radiogenic Sr and Nd isotope compositions, suggest a correlation with the New England Orogen of eastern Australia, rather than with Australia's Lachlan Orogen or other adjacent geological provinces. Our results indicate that the New England Orogen terranes continue towards New Zealand at least as far as the southern Lord Howe Rise. The projected offshore boundaries of the major east Australian orogens are now known with more confidence, and do not appear to require any major cross-orogen offsets.

    A lunar outpost will require electrical energy. One potential source is fission surface power where heat from a reactor is converted into electricity utilizing an energy conversion system, and waste heat will need to be rejected from the system. The Second Generation Radiator Demonstration Unit is a technology demonstration unit leading towards operational radiators. To approximate the infrared emittance of the lunar outpost radiators, a low-cost coating compatible with the test conditions was sought. LORD Aeroglaze A276 has a similar emittance, but its performance in air and vacuum at the desired operating temperatures was unknown. This study determined that the emittance remained above 0.86 for all conditions tested and that LORD Aeroglaze A276 is a suitable surrogate coating for the Second Generation Radiator Demonstration Unit.

  15. Observation of ultrahigh-energy cosmic rays and neutrinos from lunar orbit: LORD space experiment

    NASA Astrophysics Data System (ADS)

    Ryabov, Vladimir; Chechin, Valery; Gusev, German

    The problem of detecting highest-energy cosmic rays and neutrinos in the Universe is reviewed. Nowadays, there becomes clear that observation of these particles requires approaches based on novel principles. Projects based on orbital radio detectors for particles of energies above the CZK cut-off are discussed. We imply the registration of coherent Cherenkov radio emission produced by cascades of most energetic particles in radio-transparent lunar regolith. The Luna-Glob space mission proposed for launching in the near future involves the Lunar Orbital Radio Detector (LORD). The feasibility of LORD space instrument to detect radio signals from cascades initiated by ultrahigh-energy particles interacting with lunar regolith is examined. The comprehensive Monte Carlo calculations were carried out within the energy range of 10 (20) -10 (25) eV with the account for physical properties of the Moon such as its density, the lunar-regolith radiation length, the radio-wave absorption length, the refraction index, and the orbital altitude of a lunar satellite. We may expect that the LORD space experiment will surpass in its apertures and capabilities the majority of well-known current and proposed experiments dealing with the detection of both ultrahigh-energy cosmic rays and neutrinos. The design of the LORD space instrument and its scientific potentialities in registration of low-intense cosmic-ray particle fluxes above the GZK cut-off up to 10 (25) eV is discussed as well. The designed LORD module (including an antenna system, amplifiers, and a data acquisition system) now is under construction. The LORD space experiment will make it possible to obtain important information on the highest-energy particles in the Universe, to verify modern models for the origin and the propagation of ultrahigh-energy cosmic rays and neutrinos. Successful completion of the LORD experiment will permit to consider the next step of the program, namely, a multi-satellite lunar systems to increase the statistics and the accuracy of the experiment. Opportunities and prospects of a multi-satellite system for observation of ultrahigh-energy cosmic rays and neutrinos are also investigated. In addition, possibilities of future missions to Jovian satellites are analyzed, insofar as the largest ice planets of the Solar System (Ganymede and Europe) can be considered as convenient targets for registration of ultrahigh-energy particles by orbiting radio detectors. The expected results are compared to those for the lunar target. The conclusion is made that within the Solar System, there are no objects with better registration efficiency for ultrahigh-energy cosmic rays and neutrinos that can be utilized in space experiments of as an alternative to the future space mission Luna-Glob with the LORD orbital radio detector.

    Endemic species are assumed to have a high risk of extinction because their restricted geographic range is often associated with low abundance and high ecological specialization. This study examines the abundance of Chaetodon butterflyfishes at Lord Howe Island in the south-west Pacific, and compares interspecific differences in local abundance to the feeding behavior and geographic range of these species. Contrary to expected correlations between abundance and geographic range, the single most abundant species of butterflyfish was Chaetodon tricinctus, which is endemic to Lord Howe Island and adjacent reefs; densities of C. tricinctus (14.1 ± 2.1 SE fish per 200m(2)) were >3 times higher than the next most abundant butterflyfish (Chaetodon melannotus), and even more abundant than many other geographically widespread species. Dietary breadth for the five dominant butterflyfishes at Lord Howe Island was weakly and generally negative correlated with abundance. The endemic C. tricinctus was a distinct outlier in this relationship, though our extensive feeding observations suggest some issues with the measurements of dietary breadth for this species. Field observations revealed that all bites taken on benthic substrates by C. tricinctus were from scleractinian corals, but adults rarely, if ever, took bites from the benthos, suggesting that they may be feeding nocturnally and/or using mid-water prey, such as plankton. Alternatively, the energetic demands of C. tricinctus may be fundamentally different to other coral-feeding butterflyfishes. Neither dietary specialization nor geographic range accounts for interspecific variation in abundance of coral reef butterflyfishes at Lord Howe Island, while much more work on the foraging behavior and population dynamics of C. tricinctus will be required to understand its' abundance at this location.

    The problem of detecting cosmic rays and neutrinos of energies above the GZK cutoff is reviewed. Nowadays, it becomes clear that registration of nature's most energetic particles requires approaches based on new principles. First of all, we imply the detection of the coherent Cherenkov radio emission in cascades of ultrahigh-energy particles in radio-transparent natural dense media, i.e., ice shields of Antarctica, mineral salt, and lunar regolith. The Luna-Glob space mission planned for launching in the near future involves the Lunar Orbital Radio Detector (LORD) whose aperture for cosmic rays and neutrinos of energies E >= 1020 eV exceeds all existing ground-based arrays. The feasibility of LORD to detect radio signals from showers initiated by ultrahigh-energy particles interacting with the lunar regolith is examined. The design of the LORD space instrument and its scientific potentialities for registration of low-intense cosmic-ray particle fluxes above the GZK cut-off up to 1025 eV is discussed.

  19. Primary productivity of the Palmer Long Term Ecological Research Area and the Southern Ocean

    A major objective of the Palmer Long Term Ecological Research (Palmer LTER) project is to obtain a comprehensive understanding of the various components of the Antarctic marine ecosystem. Phytoplankton production plays a key role in this so-called high nutrient, low chlorophyll environment, and factors that regulate production include those that control cell growth (light, temperature, and nutrients) and those that control cell accumulation rate and hence population growth (water column stability, grazing, and sinking). Sea ice mediates several of these factors and frequently conditions the water column for a spring bloom which is characterized by a pulse of production restricted in both time and space. This study models the spatial and temporal variability of primary production within the Palmer LTER area west of the Antarctic Peninsula and discusses this production in the context of historical data for the Southern Ocean. Primary production for the Southern Ocean and the Palmer LTER area have been computed using both light-pigment production models [Smith, R.C., Bidigare, R.R., Prézelin, B.B., Baker, K.S., Brooks, J.M., 1987. Optical characterization of primary productivity across a coastal front. Mar. Biol. (96), 575-591; Bidigare, R.R., Smith, R.C., Baker, K.S., Marra, J., 1987.

Chlorophyll concentrations, total photosynthetically available radiation (PAR) and sea ice concentrations were derived from satellite data. These same parameters, in addition to hydrodynamic conditions, have also been determined from shipboard and Palmer Station observations during the LTER program. Model results are compared, sensitivity studies evaluated, and productivity of the Palmer LTER region is discussed in terms of its space time distribution, seasonal and interannual variability, and overall contribution to the marine ecology of the Southern Ocean.

    Calculating the Palmer Drought Severity Index (PDSI) using the Thornthwaite potential evapotranspiration (PET) method has come under recent scrutiny for overestimating drought conditions when air temperatures exceed the historical baseline. With increasing air temperatures around the world, calculating the PDSI using the Thornthwaite PET method may no longer be the appropriate option. Therefore, various researchers have called for the use of the physically-based Penman-Monteith PET method to estimate PDSI. We present an addition to the PDSI tool developed by Jacobi et al. (2013) that includes an option to use the Penman-Monteith method to calculate PET as an input to the PDSI calculations. Comparisons with a global PDSI dataset also estimated using the Penman-Monteith method indicate good spatial correlation. This addition to the Jacobi et al. (2013) tool allows users to easily calculate a suite of Palmer drought indices using Penman-Monteith potential evapotranspiration for current and future drought projections at any spatial scale.

    For the first time, an operational Fabry-Perot interferometer was deployed near the Antarctica Peninsula at the Palmer station, a US Antarctica base (64S, 64W) and makes routine observation. We will examine seasonal variation of the thermospheric winds at Palmer station. Comparison will be made between the observations and the NCAR Thermosphere Ionosphere electrodynamics General Circulation Model (TIEGCM) simulations. The TIEGCM model has different polar cap ion convection inputs (Heelis and Weimer). The results from the two different model inputs will be compared. Understanding the seasonal variation of thermospheric winds is important to the investigation of the Weddell Sea Anomaly. By comparing the observation with models, we hope to validate the TIEGCM results.

    Antibiotic resistance in aquatic bacteria has increased steadily as a consequence of the widespread use of antibiotics, but practice and international treaty should have limited antibiotic contamination in Antarctica. We estimated antibiotic resistance in microorganisms isolated from the Antarctic marine waters and a penguin rookery, for 2 reasons: (i) as a measure of human impact and (ii) as a potential "snapshot" of the preantibiotic world. Samples were taken at 4 established sampling sites near Palmer Station, which is situated at the southern end of the Palmer Archipelago (64 degrees 10'S, 61 degrees 50'W). Sites were chosen to provide different potentials for human contamination. Forty 50 mL samples of seawater were collected and colony-forming units (CFU)/mL were determined at 6 and 20 degrees C. For this study, presumed psychrophiles (growth at 6 degrees C) were assumed to be native to Antarctic waters, whereas presumed mesophiles (growth at 20 degrees C but not at 6 degrees C) were taken to represent introduced organisms. The 20-6 degrees C CFU/mL ratio was used as a measure of the relative impact to the ecosystem of presumably introduced organisms. This ratio was highest at the site nearest to Palmer Station and decreased with distance from it, suggesting that human presence has impacted the natural microbial flora of the site. The frequency of resistance to 5 common antibiotics was determined in each group of isolates. Overall drug resistance was higher among the presumed mesophiles than the presumed psychrophiles and increased with proximity to Palmer Station, with the presumed mesophiles showing higher frequencies of single and multiple drug resistance than the psychrophile population. The frequency of multidrug resistance followed the same pattern. It appears that multidrug resistance is low among native Antarctic bacteria but is increased by human habitation. PMID:19190699

    November 2013 marked the 50th anniversary of the premiere of Doctor Who, the longest-running science fiction television series in history (790 episodes spanning 1963-1989 and 2005-present). The revival of the BBC series in 2005 has been both critically acclaimed and commercially successful. The travels of the 900-plus-year-old Time Lord and his companions introduce viewers to the past, present, and future of our planet and many others. While the series is obviously fictional, there is also a surprising amount of fairly accurate science as well.

  7. Smoke emissions from industrial western Scotland in 1859 inferred from Lord Kelvin's atmospheric electricity measurements

    Lord Kelvin (William Thomson) made careful, calibrated measurements of the atmospheric Potential Gradient (PG) at three sites on the east side of Arran in 1859. The PG was always anomalously high in easterly and north-easterly winds. Positive space charge from sea spray may have contributed to the high PG at two coastal sites, but measurements made on Goatfell, inland and 100-175 m above sea level are unlikely to have been affected by spray. Instead, pollution from the Scottish mainland seems the more likely cause of the high PG at Goatfell, which varied from 300 to 1000 Vm-1 on 10th-11th October 1859, corresponding to smoke levels from 0.2 to 0.8 mgm-3. Gaussian plume calculations, based on the atmospheric conditions described by Lord Kelvin, and constrained by early Glaswegian pollution measurements, indicate a substantial source region located on the Scottish mainland, 20-40 km from Arran, emitting between 10-104 kg s-1.

  8. "Being bridges": Cleaver/Baldwin/Lorde and African-American sexism and sexuality.

    PubMed

    Waldrep, S

    1993-01-01

    In an attempt to place James Baldwin and his ideas within the context of a debate on black sexuality and sexism, this paper begins with a section on Eldridge Cleaver and his critique of Baldwin's position on sexuality and race. Cleaver's own homophobia and misreading of Baldwin's essays and published comments on Richard Wright contribute to his inability to grasp Baldwin's sophisticated analysis of race/sexuality/sexism within Western culture. The second section takes up Baldwin explicitly and attempts both to outline his position more fully and to suggest the breadth and depth of his analysis of sexuality and the work yet to be done to chart it. In the final section of the paper I turn to Audre Lorde in order to update the critique of Baldwin's position within the debate. Lorde, like many other contemporary writer-theorists, sees the terms of the discussion differently from Baldwin. She agrees with his hatred of racism, homophobia, and sexism, but she disagrees with his solution that acceptance and "brotherly" love are a solution to the real problems facing black (and gay) people today. She posits a belief in the necessity for delineating the particular subject position she holds: black, lesbian, female, Western, etc., and she is wary of any allegiances that might elide the clues to her oppression. The paper attempts to demonstrate that these differing positions are, nevertheless, linked in ways historical and otherwise. PMID:8113614

    Raoul Palmer born in Paris in 1904 from Swedish parents with a humanistic tradition and a non-conformist spirit obtained a scientific degree (licence ès-sciences) before starting his medical studies. Attracted by experimental surgery he was at the head of Fiessinger's laboratory before becoming demonstrator of gynecology at the Hôpital Broca in the services of Proust, Brocq, Macquot, Funck-Brentano and Huguier. As a surgeon specialized in sterility since 1935 but conscient as to the difficulty of making a prognosis without being informed of the extent of the lesions, he invented pre-operatory exploratory coelioscopy in 1943. This new technique allowed him to go further with the sampling of ovocytes, electrocoagulation of the uterine horns, punction of cysts, adhesiolysis ... And this was only a beginning for this method practised for the first time in 1901 by Kelling in the dog and by Jacobaeus (1912) in man but which remained confidential. In spite of neighbouring hostility, Palmer's disciples have widened the limits of this method: digestive adhesiolysis, appendectomy in 1983. In 1987 Philippe Mouret realized the first cholecystectomy and opened the way to more complex surgical operations so much that some surgeons wonder if laparotomy is still to be performed to-day. With a premonitory will, Palmer has fought all along his medical career against clandestine abortion while advising in spite of the Ordre des Médecins the legalization of voluntary pregnancy and freedom for voluntary sterilization. With over 800 international publications he appears as a visionary creator and a militating humanist. PMID:11624883

    Arthroscopic repair of peripheral dorso-ulnar triangular fibrocartilage complex (TFCC) lesions is now a preferred method. Both outside-in and inside-out techniques are commonly performed for repairing Palmer type 1B TFCC tear. But these techniques have disadvantages of making an additional skin incision to tie knots subcutaneously over the capsule. We performed an arthroscopic all-inside repair technique of Palmer type 1B TFCC tears, which is a modified method of the outside-in technique using a spinal needle. This all-inside technique is as simple as previously described arthroscopic techniques and also has advantages of vertical mattress suture and no additional incision. We recommend this technique as a useful alternative to the others for repairing Palmer type 1B TFCC tear. PMID:17668185

    Lord Howe Island and the St Kilda archipelago have many similarities, yet their communities had totally disparate outcomes. The characteristics of the two islands are compared and contrasted, and it is hypothesised that the differences in health and diseases largely explain the success of one society and the failure of the other.

    The paper "High Noon for Microfinance Impact Evaluations" by Duvendack and Palmer-Jones replicates the papers of Chemin (2008) and Pitt and Khandker (1998) that estimate the impact of microfinance in Bangladesh. My paper replicates the Duvendack and Palmer-Jones replication and finds so many serious errors in their code and misrepresentations of the methods described in their paper that I conclude that their results are spurious and provide no evidence about the validity of either the papers of Chemin or Pitt and Khandker or on the effectiveness of microfinance.

    Ultraviolet radiation-induced DNA damage frequencies were measured in DNA dosimeters and natural plankton communities during the austral spring at Palmer Station, Antarctica, during the 1999-2000 field season. We found that the fluence of solar ultraviolet-B radiation (UV-B) at the earth's surface correlated with stratospheric ozone concentrations, with significant ozone depletion observed because of "ozone hole" conditions. To verify the interdependence of ozone depletion and DNA damage in natural microbial communities, seawater was collected daily or weekly from Arthur Harbor at Palmer Station, Antarctica, throughout "ozone season," exposed to ambient sunlight between 0600 and 1800 h and fractionated using membrane filtration to separate phytoplankton and bacterioplankton populations. DNA from these fractions was isolated and DNA damage measured using radioimmunoassay. Under low-ozone conditions cyclobutane dimer concentrations in bacterioplankton and phytoplankton communities were maximal. DNA damage measured in dosimeters correlated closely with ozone concentrations and UV-B fluence. Our studies offer further support to the theory that stratospheric deozonation is detrimental to marine planktonic organisms in the Southern Ocean. PMID:11950092

    This personal commentary explores some issues that arise in the text of the interview with Lord Darzi published in LJPC 6.6, from a point of view of an interest in health policy and change in healthcare organisations. It suggests that the vision is desirable but that there are four major questions about ready implementation that the field needs to consider: 1 Can primary care development and investment be protected in a cold financial climate? 2 Does the current marketisation of health care erode integration? 3 Does the health and social care system in London behave like a real system? 4 Is there really a cultural shift towards empowerment and organisational learning?

    2015-01-01

    Lord Howe Island is an eroded remnant of a shield volcano approximately 600 km northeast of Sydney, New South Wales, Australia. It has fascinated biologists for more than a century because of its unique and iconic fauna and flora, and was declared a World Heritage Site in 1982. Although the terrestrial invertebrate fauna is reasonably well known for many groups, most Hymenoptera, apart from ants, have received scant attention. Here we use material collected from a recent intensive invertebrate survey, in conjunction with the published literature, to provide an overview of the Hymenoptera known from the island that can act as a basis for future taxonomic and biodiversity research. In doing so, we record 318 species from 31 hymenopteran families from the Island, and assess the proportion that are flightless and likely to be endemic to the island. PMID:25781836

  4. Impacts of a population outbreak of the urchin Tripneustes gratilla amongst Lord Howe Island coral communities

    NASA Astrophysics Data System (ADS)

    Valentine, J. P.; Edgar, G. J.

    2010-06-01

    Subtidal reef surveys within the Lord Howe Island Marine Park revealed that populations of the sea urchin Tripneustes gratilla underwent an explosive outbreak in some regions of the park over a 2-year period. This urchin was rare or absent during 2006 surveys at 33 sites studied, but at sites off northern Lord Howe Island in 2008, densities averaged >1.3 m-2. Dramatic increases in T. gratilla density (exceeding 4 m-2) were observed at some sites. We quantify community-level impacts of T. gratilla using ‘before-after’ and ‘control-impact’ data. Zones closed to fishing exhibited similar increases in T. gratilla density to zones open to fishing. Although not previously reported as a keystone species affecting coral habitat, T. gratilla was found to possess an ‘ecosystem engineer’ function. Outbreak sites were characterised by significant declines in cover of foliose algae, including red algae, which decreased from 11.2% in 2006 compared to 2.5% in 2008. Brown foliose algae also declined at sites where T. gratilla outbreaks occurred, averaging 20.4% in 2006 compared to 1.8% in 2008. By contrast, crustose coralline algal cover increased at sites where high T. gratilla densities were observed, from 2.7% in 2006 to an average of 42.6% in 2008. We found no clear indication of impacts on sessile invertebrates or flow-on effects to other levels of the food web, with no significant change in coral cover or densities of mobile invertebrates or fish populations associated with the T. gratilla outbreak.

In addition, data for 1355 Magoeba from 2006 were re-analyzed. The periods derived from the 2006 and 2009 apparitions cannot be reconciled. The solution based on the 2009 data has been adopted as the one more likely correct. For four of the asteroids, 2001 Einstein, 3086 Kalbaugh, 4736 Johnwood, and 5841 Stone, the 2009 data were combined with those from earlier apparitions to derive spin axis and shape models.

  10. Effects of temperature anomalies on the Palmer Drought Severity Index in the central United States

    2000-01-01

    The purpose of this study is to improve our understanding of temperature and precipitation effects on the Palmer Drought Severity Index (PDSI). Both theoretical and observational analyses were applied to separate and compare temperature and precipitation effects on PDSI. The results showed that because of the dependence of PDSI on the 'climatologically appropriate rainfall', which is a function of time and varies with surface air temperature, the PDSI can be equally affected by temperature and precipitation, when both have similar magnitudes of anomalies. Calculations using observational data further illustrated the temperature influence on PDSI in different climate regions in the central United States. The temperature effect on PDSI complicates the usage of the index in interpreting precipitation anomalies and its application in inferring precipitation variations, particularly from reconstructed PDSI.

  11. Bursts of cloud condensation nuclei (CCN) by dissipating clouds at Palmer Station, Antarctica

    The authors present here a case study of cloud-mediated production of cloud condensation nuclei (CCN) recorded at Palmer Station (64{degrees}46`S, 64{degrees}05`W), Antarctica on 20 Jan 1994. Four instances of CCN bursts occured on January 17, 19, 20 and February 7, 1994 when cloud base descended to the surface and dissipated under prevailing meteorlogical conditions. The most spectacular event ocurred on January 20 when the CCN concentration was enhanced by a factor of four at 0.025% supersaturation (with respect to water) compared to the prevent concentration. At 1.25% supersaturation, the corresponding enhancement was by a factor of seven. This indicated a larger production of aerosol particles in smaller size ranges. The elevated CCN concentrations were measured for over fifteen hours. The CCN activity spectrum during the event resembled the ones that are typical of previous measurements in the urban plumes of St. Louis and Denver. 30 refs., 3 figs.

    2013-05-01

    In the two decades since the first asteroid satellite was discovered, more than 200 are now known. Many of the discoveries have been made as part of pro-am collaborations involving lightcurve photometry where satellites are revealed by deviations in the lightcurve. These mutual events are due to occultations and/or eclipses involving the satellite. On rare occasions, shadow transits have also been seen. Asteroid photometry work in the past year or so at the Palmer Divide Observatory (PDO) in Colorado has led to the discovery of no less than four new binary asteroids. A review will be given of the photometry program at PDO and methods used to find the tracks of satellites in the lightcurve trail as well as some specific examples of PDO discoveries.

    Lightcurves for 46 near-Earth asteroids (NEAs) were obtained at the Center for Solar System Studies-Palmer Divide Station (CS3-PDS) from 2015 June-September. Four of the asteroids showed indications of non-principal axis rotation (NPAR), or tumbling, (9400) 1994 TW1, (86666) 2000 FL10, (154807) 2004 PP97, and (206378) 2003 RB, but there were insufficient data for full analysis. On the other hand, 2015 JY1 is a confirmed tumbler with a dominate period of 6.442 h and a likely second period of 11.42 h. Evidence of the satellite for the known binary system (385186) 1994 AW1 was found. The estimated size ratio of Ds/Dp >= 0.25 is in good agreement with earlier results.

  16. Relativity in Transylvania and Patusan: Finding the roots of Einstein's theories of relativity in "Dracula" and "Lord Jim"

    NASA Astrophysics Data System (ADS)

    Tatum, Brian Shane

    This thesis investigates the similarities in the study of time and space in literature and science during the modern period. Specifically, it focuses on the portrayal of time and space within Bram Stoker's Dracula (1897) and Joseph Conrad's Lord Jim (1899-1900), and compares the ideas presented with those later scientifically formulated by Albert Einstein in his special and general theories of relativity (1905-1915). Although both novels precede Einstein's theories, they reveal advanced complex ideas of time and space very similar to those later argued by the iconic physicist. These ideas follow a linear progression including a sense of temporal dissonance, the search for a communal sense of the present, the awareness and expansion of the individual's sense of the present, and the effect of mass on surrounding space. This approach enhances readings of Dracula and Lord Jim, illuminating the fascination with highly refined notions of time and space within modern European culture.

    PubMed

    Kang, Nancy

    2016-01-01

    This article argues that African-American director Dee Rees' critically acclaimed debut Pariah (2011) is a rewriting of lesbian poet-activist Audre Lorde's iconic "bio-mythography" Zami: A New Spelling of My Name (1982). The article examines how Rees' work creatively and subtly re-envisions Lorde's Zami by way of deeply rooted and often cleverly camouflaged patterns, resonances, and contrasts. Shared topics include naming, mother-daughter bonds, the role of clothing in identity formation, domestic abuse, queer time, and lesbian, gay, bisexual, and transgender legacy discourse construction. What emerges between the visual and written texts is a hidden language of connection-what may be termed Black lesbian steganography-which proves thought-provoking to viewers and readers alike.

  18. The Courage to Teach: Exploring the Inner Landscape of a Teacher's Life (by Parker J. Palmer)

    NASA Astrophysics Data System (ADS)

    Hurt Middlecamp, Reviewed By Catherine

    1999-12-01

    Most of us would willingly - perhaps even passionately - tackle the question of what we should teach our students. Similarly, we are likely to engage in a conversation about how we teach and our preferences for organizing classroom time and structures. Although the question of why we teach may be raised less often (and perhaps with a hint of sarcasm), this too is a question to which most can offer a thoughtful response. An entirely different matter, however, is the question of who is the person teaching. This who involves the inner realms of one's heart, mind, and soul. How does our identity affect the teaching and learning processes? As we teach, what paths are we following intellectually, emotionally, or even spiritually? How do these paths influence our relationship to our content and to our students? With an engaging honesty, Parker Palmer pursues these questions in The Courage to Teach: Exploring the Inner Landscape of A Teacher's Life. At the outset he points out (p 4): I have no quarrel with the what or how or why questions - except when they are posed as the only questions worth asking. All of them can yield important insights into teaching and learning. But none of them opens up the territory I want to explore in this book: the inner landscape of the teaching self. One might well question why those of us teaching chemistry should be interested in examining ourselves as part of the teaching equation. Isn't scientific knowledge supposed to be as objective as we can make it? Isn't it better for us to check our emotional or intellectual baggage at the classroom door, rather than to taint the content with our biases? Or perhaps more directly stated, is it not more practical and a better use of our time to simply deal with the realities of the day-to-day classroom issues? Admittedly these are fair questions. However, to become stuck on them is to miss the opportunities for reflection and growth as teachers that Palmer's book offers. Simply put, people teach. Without putting the human factor into the teaching equation, you miss one of the key variables. In the early chapters, Palmer offers the readers simple statements to entice them to delve more deeply into his later discussions. "Good teaching cannot be reduced to technique; good teaching comes from the identity and integrity of the teacher," or, "Bad teachers distance themselves from the subject they are teaching - and in the process, from their students," or ultimately, "Only one resource is at my immediate command: my identity, my selfhood, my sense of this 'I' who teaches - without which I have no sense of the 'Thou' who learns." Readers can expect to find both ideas and a personal honesty on Palmer's part that inspires one to accept human limitations and evokes a gentle chuckle at our good days...and at our bad ones as well. Palmer has strong credentials to write about the self as teacher. In recent years, he has been a visiting faculty member at Beloit College, Berea College, and Georgetown University. Over past few decades, he has written extensively on the teaching and learning process, including To Know as We Are Known: Education as a Spiritual Journey (1983). He holds a Ph.D. from the University of California at Berkeley and has lived and taught in a variety of settings and communities around the globe. Woven through his writings is a sense of both the human and the spiritual dimensions of being a teacher. Thus, those who most might appreciate his reflections are comfortable with language drawn from spiritual traditions. Palmer spent a number of years as teacher and writer-in-residence at Pendle Hill, a Quaker community in Pennsylvania, and the respect and appreciation that he holds for silence and reflection come through in his writing. Expect to find no religious dogma or prescriptions in what he offers. What might those of us who teach chemistry expect to gain from this book? One possibility offered at the start is his examination of fear as a part of human nature that affects our teaching. Chapter 3 is entitled "A Culture of Fear: Education and the Disconnected Life". He admits his own anxieties and their consequences (p 29): Driven by my fear, ...I strive to make my on-stage performance slicker and smoother - and in the process make it less and less likely that my students will learn anything other than how to cover up and show off. I conceal my own fear and am unable to weave the fabric of connectedness that teaching and learning require. He poses to the reader the question of how we can transcend fear and reconnect with reality for the sake of teaching and learning. As we train our teaching staff members and future chemistry teachers, both directly (by what we say) and indirectly (by who we are), a discussion of this fear within might set the tone for more honest dialogue about ourselves as teachers. Another possibility is his discussion of the concept of paradox in teaching in learning. In Chapter 6, entitled "The Hidden Wholeness: Paradox in Teaching and Learning", he notes that our tendency to categorize and divide can have severe consequences. For example, we separate head from heart, facts from feelings, theory from practice, and teaching from learning. As a result, we may produce "minds that do not know how to feel and hearts that do not know how to think" or "teachers who talk but do not listen and students who listen but do not talk." Quoting Niels Bohr, he points out "the opposite of a true statement is a false statement, but the opposite of a profound truth can be another profound truth." Palmer explains (p 66): Paradoxical thinking requires that we embrace a view of the world in which opposites are joined, so that we can see the world clearly and see it whole. ...The result is a world more complex and confusing than the one made simplistic by either/or thought - but that simplicity is merely the dullness of death. When we think things together, we reclaim the life force in the world, in our students, in ourselves. As we teach our courses, we might similarly reflect on the consequences of the categories we use. For example, in using the categories majors and non-majors, we may not be recognizing the strengths that both bring. In viewing science as distinct from other fields, we may lose the real-world connections of science to society. And in focusing on finding "the answer" to textbook and exam questions, we may miss the possibility of there being several (or no) possible answers. In the final chapters, Palmer writes about community and what we can gain by both teaching in community and learning from our colleagues in community. In regard to the latter, he notes the "privatization" of what we do, that is, our tendency to teach solo and out of collegial sight. As a result, we have little or no shared experience related to our teaching and therefore don't tend to speak with our colleagues about what happened or needs to happen next. He points out (p 144) that When any function is privatized, the most likely outcome is that people will perform it conservatively, refusing to stray far from the silent consensus on what "works"even when it clearly does not. In Palmer's opinion, teaching at the college level has evolved slowly because of its privatization. If we were to engage in "good talk about good teaching", this would "enhance both our professional practice and the selfhood from which it comes." He views these conversations as a "professional obligation" that we should expect of ourselves and of others. In these chapters, the reader will find practical suggestions for how a more public discourse about teaching could be accomplished. As one might guess, I have been a fan of Palmer's books over the years. His writings have withstood the test of time and continue to offer thoughtful reflections to any interested in the art of teaching in its many dimensions. As might be expected, my copy of this book has had no time to gather dust on my shelf, as it keeps making the rounds. If by now somebody hasn't loaned you a copy of The Courage to Teach, you might want to get your own. More likely than not, there will be a hole in your bookshelf where it belongs.

Its most famous member is the Lord Howe Island stick insect Dryococelus australis (Montrouzier), which was believed to have become extinct but was rediscovered in 2001 and is considered to be one of the rarest insects in the world. To resolve the evolutionary position of Dryococelus, we constructed a phylogeny from approximately 2.4 kb of mitochondrial and nuclear sequence data from representatives of all major phasmatodean lineages. Our data placed Dryococelus and the New Caledonian tree lobsters outside the New Guinean Eurycanthinae as members of an unrelated Australasian stick insect clade, the Lanceocercata. These results suggest a convergent origin of the 'tree lobster' body form. Our reanalysis of tree lobster characters provides additional support for our hypothesis of convergent evolution. We conclude that the phenotypic traits leading to the traditional classification are convergent adaptations to ground-living behaviour. Our molecular dating analyses indicate an ancient divergence (more than 22 Myr ago) between Dryococelus and its Australian relatives. Hence, Dryococelus represents a long-standing separate evolutionary lineage within the stick insects and must be regarded as a key taxon to protect with respect to phasmatodean diversity.

    The two species of the palm genus Howea (Arecaceae) from Lord Howe Island, a minute volcanic island in the Tasman Sea, are now regarded as one of the most compelling examples of sympatric speciation, although this view is still disputed by some authors. Population genetic and ecological data are necessary to provide a more coherent and comprehensive understanding of this emerging model system. Here, we analyse data on abundance, juvenile recruitment, pollination mode and genetic variation and structure in both species. We find that Howea forsteriana is less abundant than Howea belmoreana. The genetic data based on amplified fragment length polymorphisms markers indicate similar levels of variation in the two species, despite the estimated census population size of H. belmoreana being three times larger than that of H. forsteriana. Genetic structure within species is low although some weak isolation by distance is detectable. Gene flow between species appears to be extremely limited and restricted to early-generation hybrids - only three admixed individuals, classified as F2s or first generation backcrosses to a parental species, were found among sampled palms. We conclude that speciation in Howea was indeed sympatric, although under certain strict definitions it may be called parapatric. PMID:19674301

  1. Simpson's Paradox, Lord's Paradox, and Suppression Effects are the same phenomenon – the reversal paradox

    This article discusses three statistical paradoxes that pervade epidemiological research: Simpson's paradox, Lord's paradox, and suppression. These paradoxes have important implications for the interpretation of evidence from observational studies. This article uses hypothetical scenarios to illustrate how the three paradoxes are different manifestations of one phenomenon – the reversal paradox – depending on whether the outcome and explanatory variables are categorical, continuous or a combination of both; this renders the issues and remedies for any one to be similar for all three. Although the three statistical paradoxes occur in different types of variables, they share the same characteristic: the association between two variables can be reversed, diminished, or enhanced when another variable is statistically controlled for. Understanding the concepts and theory behind these paradoxes provides insights into some controversial or contradictory research findings. These paradoxes show that prior knowledge and underlying causal theory play an important role in the statistical modelling of epidemiological data, where incorrect use of statistical models might produce consistent, replicable, yet erroneous results.

    On Lord Howe Island, speciation is thought to have taken place in situ in a diverse array of distantly related plant taxa (Metrosideros, Howea and Coprosma; Proc. Natl Acad. Sci. USA 108, 2011, 13188). We now investigate whether the speciation processes were driven by divergent natural selection in each genus by examining the extent of ecological and genetic divergence. We present new and extensive, ecological and genetic data for all three genera. Consistent with ecologically driven speciation, outlier loci were detected using genome scan methods. This mechanism is supported by individual-based analyses of genotype-environment correlations within species, demonstrating that local adaptation is currently widespread on the island. Genetic analyses show that prezygotic isolating barriers within species are currently insufficiently strong to allow further population differentiation. Interspecific hybridization was found in both Howea and Coprosma, and species distribution modelling indicates that competitive exclusion may result in selection against admixed individuals. Colonization of new niches, partly fuelled by the rapid generation of new adaptive genotypes via hybridization, appears to have resulted in the adaptive radiation in Coprosma - supporting the 'Syngameon hypothesis'.

    LORD Corporation has recently developed glycol-based MR fluids for use in applications such as engine mounts and bushing, in which the MR fluid will contact rubber and other oil-sensitive elastomers. To demonstrate the performance characteristics of these fluids, prototype MR engine mounts were designed and their dynamic stiffness and damping were tested. In one configuration, the MR mount contained a simple MR valve and was filled with a glycol fluid containing 22% iron by volume. This mount had low dynamic stiffness and frequency-dependent damping in the off-state and higher dynamic stiffness with little damping in the on-state. The low-frequency stiffness and damping could be varied by adjusting the applied magnetic field. In a second mount configuration, the mount contained both an MR valve and an inertia track. Two such mounts were evaluated with MR fluids containing 22% and 36% iron, respectively. In the off-state, both mounts displayed low stiffness and damping as fluid flowed through the MR valve. In the on-state, the MR valve was closed and the inertia track was activated, giving characteristic frequency-dependent stiffness and damping that could be tuned by varying the strength of the magnetic field. These behaviors were observed at both low and high displacements of the mount.

    An aquarium-maintained female Red Irish Lord Hemilepidotus hemilepidotus presented with severe coelomic distension. The fish was anesthetized for ultrasonographic examination, which highlighted multiple cyst-like lesions in the liver and a distended ovary that was filled with follicles and an inspissated egg mass. Multiple exploratory celiotomies were performed for egg mass removal, liver biopsy, ovariosalpingectomy, and body wall rupture repair. Fourteen weeks after original presentation, and subsequent to 2 weeks of anorexia, the fish died. At necropsy, the liver was severely enlarged and distorted by multiple, coalescing, cyst-like spaces with no grossly normal liver parenchyma. The spleen also contained a raised cyst-like structure. Microscopically, the liver had well-demarcated foci of hepatocyte loss with retained meshworks of interconnected, perisinusoidal stellate cells. The fluid-filled spaces surrounded by stellate cells were not lined by epithelium or endothelium. The spleen had similar fluid-filled spaces formed of stellate cells. The cyst-like lesions in the liver were consistent with spongiosis hepatis; however, the concurrent development of a morphologically comparable lesion in the spleen is not typical of spongiosis hepatis cases. This case may represent the first report of spontaneously occurring spongiosis hepatis in a fish maintained in a public aquarium, as well as the first report in a fish of spongiosis hepatis-like lesions in an organ other than the liver.

    Lithodid crabs (and other skeleton-crushing predators) may have been excluded from cold Antarctic continental shelf waters for more than 14 Myr. The west Antarctic Peninsula shelf is warming rapidly and has been hypothesized to be soon invaded by lithodids. A remotely operated vehicle survey in Palmer Deep, a basin 120 km onto the Antarctic shelf, revealed a large, reproductive population of lithodids, providing the first evidence that king crabs have crossed the Antarctic shelf. DNA sequencing and morphology indicate the lithodid is Neolithodes yaldwyni Ahyong & Dawson, previously reported only from Ross Sea waters. We estimate a N. yaldwyni population density of 10 600 km?2 and a population size of 1.55 × 106 in Palmer Deep, a density similar to lithodid populations of commercial interest around Alaska and South Georgia. The lithodid occurred at depths of more than 850 m and temperatures of more than 1.4°C in Palmer Deep, and was not found in extensive surveys of the colder shelf at depths of 430–725 m. Where N. yaldwyni occurred, crab traces were abundant, megafaunal diversity reduced and echinoderms absent, suggesting that the crabs have major ecological impacts. Antarctic Peninsula shelf waters are warming at approximately 0.01°C yr?1; if N. yaldwyni is currently limited by cold temperatures, it could spread up onto the shelf (400–600 m depths) within 1–2 decades. The Palmer Deep N. yaldwyni population provides an important model for the potential invasive impacts of crushing predators on vulnerable Antarctic shelf ecosystems. PMID:21900324

    The Lord of Rings - the mysterious case of the stolen rings: a critical analysis S. Sandrelli INAF - Osservatorio Astronomico di Brera, Milano, Italy (stefano.sandrelli@brera.inaf.it / Fax: 02 72001600 / Phone: +39 02 72320337) "The Lord of Rings - the mysterious case of the stolen rings" is a live astronomical role-playing game for kids aged 10 -13. Its goal is to introduce them to some of the main topics of the Solar System: a) the role of gravity; b) the distribution of mass & light; c) the effects of rotation; d) the distribution of water. The game was held both at the Perugia (2004) and the Genova Science Festival (2005), obtaining great success. Teams of about 6-8 members are introduced to Mr Schioppanelli, the astro-detective of the town (the name is a pun: it reminds Schiaparelli, the famous italian astronomer, and it is a slang expression meaning "ring-breaker"). Mr Schioppanelli has his office in an "gastronomical astronomical observatory", known as The Red Giant Pizzeria. Schioppanelli informs the kids that a mysterious Centaur succeded in stealing the rings of Saturn. The partecipants are appointed astro-detectives in-charge and asked to find the rings by browsing around the Solar System, which is scaled so as to fit the town historical centre or a pedestrian area, going from the Sun to Saturn or beyond, depending on the actual area at disposal. Great care must be taken allowing children playing only in a car-free area of the town. At the right scaled distances, the partecipants meet characters playing as the various planets. The kids can talk to them after solving a riddle, obtaining useful informations. A special characters play as a comet, timely going in and out of the inner solar system. The teams can also talk to some shepherd-moons of the rings. They easily discover that the rings were totally destroyed by the Centaur: a real disaster! They are also suggested to gather the necessary ingredients (gravity, light, rotation, inclination, dust and water, represented by simple objects like apples, spinning tops and so on) to re-build the rings. The kids can buy the ingredients from different planets: every planet has ingredients in quantities which are proportionate to the real physical properties of that celestial object. After collecting the ingredients, they must carry them to the "The Red Giant" and indicate their best recipe to Mr Schioppanelli. Depending on the recipe, rings can be too strict or too luminous or too fast rotating and so on. The winning group is the one which prepares the best recipe to cook the rings in the smallest amount of time. After presentig this specific (and mysterious) case, we analyse the advantage- disadvantage ratio of such an activity, beeing as funny as dispersive.

    Drought roots in natural climate variability over mid- to long-term time periods and often causes serious water and environmental consequences for human societies and ecosystems. Due to the random nature of contributing factors, occurrence and severity of droughts may be treated by stochastic techniques. Early indication of droughts can help to activate the corresponding mitigation strategies and measures in advance. Therefore, drought forecasting comes to the aid of decision makers for planning and management of water resource systems. In arid and semi-arid regions, drought negative effects on crops may be reduced by storing sufficient water from available sources. As a result, it is quite important to forecast the drought duration in the growing season in terms of irrigation scheduling. In this study, duration of agriculture droughts, quantified by the Palmer Drought Severity Index (PDSI), is forecasted through the application of linear stochastic models for Mashhad, Khorasan-Razavi province, northwest of Iran. Study of the temporal characteristics of droughts indicated that the region is affected by severe and, more or less, prolonged droughts from 1971 to 2004. Results showed that over 64% of the studied period, droughts prevailed that increased in duration and severity in recent years. A SARIMA (Seasonal Autoregressive Integrated Moving Average) model was developed to predict drought duration and was found to provide acceptable results up to 2 months ahead.

    Crassulacean acid metabolism (CAM) is widespread in terrestrial and aquatic species, plastic in response to environmental changes. Isoetes L. is one of the earliest basal vascular plants and CAM is popular in this genus. Isoetes sinensis Palmer is an amphibious species, alternating frequently between terrestrial and aquatic environments. Given this, we investigated and compared photosynthetic characteristics over a diurnal cycle under submerged condition (SC) and terrestrial condition (TC). The results suggest that I. sinensis possesses a stronger CAM capacity under SC. Compared with under TC, titratable acidity levels and organic acid concentrations were more enriched under SC, whereas soluble sugar or starch and protein levels were lower under SC. Transcript analyses for nine photosynthetic genes revealed that CAM-associated genes possessed high transcripts under SC, but C3-related transcripts were highly expressed under TC. In addition, the enzyme activity measurements demonstrated that PEPC activity over a diurnal cycle was slightly higher under SC, whereas Rubisco activity during the daytime was greater under TC. This comprehensive study probably facilitates general understandings about the CAM photosynthetic characteristics of Isoetes in response to the environmental changes. PMID:26634994

    Isoetes sinensis Palmer (Isoetaceae) is a critically endangered fern that is a marsh plant (that is an aquatic or amphibious plant) in China. To evaluate damage or influence of lead (Pb) on cell ultrastructure in I. sinensis, we used 2000mg·L-1 Pb(NO3)2 solution to treat I. sinensis for 35d, and used transmission electron microscope (TEM) to observe the cell ultrastructure of leaf blades and roots of the plant. Our results indicated that Pb induced distinct changes of the organelles including chloroplast, mitochondria, nucleolus and vacuole. The level of damage organ was lower leaf > upper leaf > root The typical performance of the damages caused by lead shown that part of the nucleolus cracked; the cristae dilated, matrix vacuolized and membrane structure blurred in mitochondria; the vacuole cracked; grana lamella decreased, stroma lamella loosed, starch grains decreased, and membrane structure was disrupted in chloroplasts; Pb deposits were present on cell wall. The damages to chloroplasts and mitochondria were relatively severe, while damage to the nucleus was relatively lighter. The damage to the cell ultrastructure of leaf blades with direct contact with Pb was more severe than that without direct contact with Pb. PMID:26407078

    Dominant modes of individual and joint variability in global sea surface temperatures (SST) and global Palmer drought severity index (PDSI) values for the twentieth century are identified through a multivariate frequency domain singular value decomposition. This analysis indicates that a secular trend and variability related to the El Niño–Southern Oscillation (ENSO) are the dominant modes of variance shared among the global datasets. For the SST data the secular trend corresponds to a positive trend in Indian Ocean and South Atlantic SSTs, and a negative trend in North Pacific and North Atlantic SSTs. The ENSO reconstruction shows a strong signal in the tropical Pacific, North Pacific, and Indian Ocean regions. For the PDSI data, the secular trend reconstruction shows high amplitudes over central Africa including the Sahel, whereas the regions with strong ENSO amplitudes in PDSI are the southwestern and northwestern United States, South Africa, northeastern Brazil, central Africa, the Indian subcontinent, and Australia. An additional significant frequency, multidecadal variability, is identified for the Northern Hemisphere. This multidecadal frequency appears to be related to the Atlantic multidecadal oscillation (AMO). The multidecadal frequency is statistically significant in the Northern Hemisphere SST data, but is statistically nonsignificant in the PDSI data.

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation in Materials Science and Engineering. Under the new structure, journal development became an increasingly important part of his job. At about the same time, Richard was also asked to take over running Reports on Progress in Physics, which up to then had been done by the head of the IOP Journals Department, Kurt Paulus. In 1989, Journal of Physics C: Solid State Physics and Journal of Physics F: Metal Physics remerged to form JPCM. Since then, Richard has gradually shed his other journal responsibilities, except for Reports on Progress in Physics, to build up JPCM. He has worked closely with four Editors-in-Chief of Journal of Physics C: Solid State Physics, five of JPCM, five of Reports on Progress in Physics and about ten of other journals, and attended approximately 300 Editorial Board meetings. I should say that he has made my own tenure at Editor-in-Chief an easy task to learn and take on, and has been a major guiding light in the development of the journal. In 2006, Richard was honoured by the award of a Member of the British Empire (MBE) for services to science publishing. Those of us on the board were particularly pleased about this, as one is not always recognized for the effort they expend, and this award was certainly due for Richard. We are going to miss Richard a great deal, but are happy that he will remain on a part time basis to help our new Publisher, Dr Lucy Smith, and the rest of us through the transition. His retirement leaves us with a huge hole that we will have to work extremely hard to fill. Speaking for the various boards, and especially the executive board, I want to wish Richard the very best in his retirement.

    Introduction Lord total hip prosthesis was discontinued due to high revision rates of the smooth threaded acetabular component and negative effects of stress shielding in the proximal femur. Presentation of case We report the outcome of a Lord cementless femoral stem, in a 55-year-old woman. In 1984, the patient underwent a Lord total hip arthroplasty for the treatment of advanced dysplastic osteoarthritis of the left hip. After 12 years, the cementless acetabular component of the prosthesis had been revised due to aseptic loosening. An acetabular metallic support ring and a cemented polyethylene cup were implanted, the femoral stem was not changed. The acetabular bone loss was reconstructed with morsellised cancellous bone allografts by the impacting technique. No complications were reported during the period of 19 years of the postoperative course. At the last clinical and radiological evaluations, the patient presented an asymptomatic hip and expressed high degree of satisfaction with the surgery result. The femoral stem was stable, with no measurable subsidence or radiolucent lines around the stem. Discussion Several reports have presented a high clinical success rate with the fully-porous-coated Lord femoral stem in both primary and revision cases. However, the long-term results showed a substantial rate of proximal femoral bone loss and thigh pain. Conclusion In our case, the Lord stem showed an excellent long-term result at the 31-year follow-up. To our knowledge, there is no published report with results of the Lord stem longer than 26-year’s follow-up. PMID:26708946

A popular jingle of the time relating to Dawson was recalled in a leading article in The Times newspaper in 1986. Knowing that a similar rhyme was in circulation involving Lord Horder of Ashford, I wrote to his son in order to verify exactly what this was; his reply is reproduced in this article. PMID:16607408

  19. Delineating depth to bedrock beneath shallow unconfined aquifers: a gravity transect across the Palmer River Basin.

    In view of the increasing demand on ground water supplies in the northeastern United States, it is imperative to develop appropriate methods to geophysically characterize the most widely used sources of ground water in the region: shallow unconfined aquifers consisting of well-sorted, stratified glacial deposits laid down in bedrock valleys and channels. The gravity method, despite its proven value in delineating buried bedrock valleys elsewhere, is seldom used by geophysical contractors in this region. To demonstrate the method's effectiveness for evaluating such aquifers, a pilot study was undertaken in the Palmer River Basin in southeastern Massachusetts. Because bedrock is so shallow beneath this aquifer (maximum depth is 30 m), the depth-integrated mass deficiency of the overlying unconsolidated material was small, so that the observed gravity anomaly was on the order of 1 milligal (mGal) or less. Thus data uncertainties were significant. Moreover, unlike previous gravity studies elsewhere, we had no a priori information on the density of the sediment. Under such circumstances, it is essential to include model constraints and weighted least-squares in the inversion procedure. Among the model constraints were water table configuration, bedrock outcrops, and depth to bedrock from five water wells. Our procedure allowed us to delineate depth to bedrock along a 3.5 km profile with a confidence interval of 1.8 m at a nominal depth of 17 m. Moreover, we obtained a porosity estimate in the range of 39% to 44%. Thus the gravity method, with appropriate refinements, is an effective tool for the reconnaissance of shallow unconfined aquifers. PMID:11554251

    Lightcurves for 41 asteroids were obtained at the Palmer Divide Observatory (PDO) from 2011 December to 2012 March: 77 Frigga, 2933 Amber, 3352 McAuliffe, 3483 Svetlov, 4031 Mueller, 5378 Ellyett, 5579 Uhlherr, 5771 Somerville, 6087 Lupo, 6602 Gilclark, (6618) 1936 SO, 6635 Zuber, (8404) 1995 AN, (9873) 1992 GH, (11058) 1991 PN10, (16421) 1988 BJ, (16426) 1988 EC, (16585) 1992 QR, 16589 Hastrup, 18368 Flandrau, (19537) 1999 JL8, (23974) 1999 CK12, (24465) 2000 SX155, (26383) 1999 MA2, (30856) 1991 XE, (39618) 1994 LT, (45898) 2000 XQ49, (47983) 2000 XX13, (49566) 1999 CM106, (49678) 1999 TQ7, (50991) 2000 GK94, (57739) 2001 UF162, (63260) 2001 CN, (69350) 1993 YP, 79316 Huangshan, (82066) 2000 XG15, (82078) 2001 AH46, (105155) 2000 NG26, (141018) 2001 WC47, (256700) 2008 AG3, (320125) 2007 EQ185. Two asteroids showed indications of being binary. Analysis of the data for near-Earth asteroid, 3352 McAuliffe showed a second period of 20.86 h but no obvious mutual events (occultations and/or eclipses). The Hungaria asteroid, (24465) 2000 SX15, displayed similar characteristics. Furthermore, the primary (or only) period of 3.256 h cannot be reconciled with analysis from previous apparitions. Three asteroids showed signs of being in non-principal axis rotation (NPAR, "tumbling"). New values for absolute magnitude (H) were found for several Hungaria asteroids using either derived or assumed values of G. These new values were compared against those used in the WISE mission to determine diameters and albedos. In all cases where the WISE results featured an unusually high albedo for the asteroid in question, the new value of H resulted in an albedo that was significantly lower and closer to the expected value for type E asteroids, which are the likely members of the Hungaria collisional family.

    The aim of this article is to demonstrate that the ruling commonly cited as the original precedent(1) for the doctrine that, at common law, medical practitioners' duty of confidentiality to their patients does not apply to court testimony,(2) did not, in fact, establish any such theory. The ruling by Lord Mansfield was made in the context of cross-examination by the Crown of a medical witness in the course of the trial of the Duchess of Kingston (Duchess of Kingston's Case (1776) 20 Howell's State Trials 355; [1775-1802] All ER Rep 623; [1776] 1 Leach 146), and this article will look briefly at: (1) the fascinating life of Elizabeth Chudleigh, the Dowager Duchess of Kingston, and the main events that led to her trial for bigamy; (2) the cross-examination of Caesar Hawkins and the different perceptions of the scope of confidentiality held by 18th century lawyers on the one hand and medical practitioners on the other; (3) Lord Mansfield's ruling that witnesses cannot withhold from the court facts which the law considers to be in the public domain; (4) the subsequent wide interpretation, usually as judicial obiter dicta, of its final paragraph during the 19th century, including early jurisprudential responses to the principle of medical confidentiality; and (5) the influence of John Henry Wigmore's opposition to patients' evidentiary privilege at common law during the twentieth century.

    DNA damage is tightly associated with various biological and pathological processes, such as aging and tumorigenesis. Although detection of DNA damage is attracting increasing attention, only a limited number of methods are available to quantify DNA lesions, and these techniques are tedious or only detect global DNA damage. In this study, we present a high-sensitivity long-run real-time PCR technique for DNA-damage quantification (LORD-Q) in both the mitochondrial and nuclear genome. While most conventional methods are of low-sensitivity or restricted to abundant mitochondrial DNA samples, we established a protocol that enables the accurate sequence-specific quantification of DNA damage in >3-kb probes for any mitochondrial or nuclear DNA sequence. In order to validate the sensitivity of this method, we compared LORD-Q with a previously published qPCR-based method and the standard single-cell gel electrophoresis assay, demonstrating a superior performance of LORD-Q. Exemplarily, we monitored induction of DNA damage and repair processes in human induced pluripotent stem cells and isogenic fibroblasts. Our results suggest that LORD-Q provides a sequence-specific and precise method to quantify DNA damage, thereby allowing the high-throughput assessment of DNA repair, genotoxicity screening and various other processes for a wide range of life science applications.

    Purpose: In South Korean ferry disaster in 2014, the captain abandoned the ship with passengers including high school students still aboard. We noticed the resemblance of abandoning the ship with passengers still aboard the ferry (named the Sewol) and the ship Patna, which was full of pilgrims, in Joseph Conrad’s novel “Lord Jim.” The aim of this study is to see how medical students think about the role of a medical doctor as a captain of a ship by analyzing book reports on Conrad’s “Lord Jim.” Methods: Participants included 49 third-year medical students. Their book reports were analyzed. Results: If placed in the same situation as the character of Jim, 24 students of the 49 respondents answered that they would stay with the passengers, while 18 students indicated they would escape from the ship with the crew. Most of the students thought the role of a doctor in the medical field was like that of a ‘captain.’ The medical students reported that they wanted to be a doctor who is responsible for his or her patients, highly moral, warm-hearted, honest, and with high self-esteem. Conclusion: In conclusion, we found that “Lord Jim” induced the virtue of ‘responsibility’ from the medical students. Consequently, “Lord Jim” could be good teaching material for medical humanities.

My paper replicates the Duvendack and Palmer-Jones replication and finds so many serious errors in their code and misrepresentations of the methods described in their paper that I conclude that their results are spurious and provide no evidence about the validity of either the papers of Chemin or Pitt and Khandker or on the effectiveness of microfinance.

    Droughts affect every region of the world and can have a significant impact on human and natural systems. Therefore the need to better understand the spatiotemporal variability of droughts is of great importance. The Palmer Drought Severity Index (PDSI) is often used as an indicator of drought, requiring only precipitation, air temperature, and potential evapotranspiration (PET) as inputs. PET using the Thornthwaite method is commonly used as an input for PDSI. However, calculating PDSI using the Thornthwaite PET method has come under recent scrutiny for overestimating drought conditions when air temperatures exceed the historical baseline. With increasing air temperatures around the world, calculating PDSI using the Thornthwaite PET method may no longer be an appropriate option. Therefore, various researchers have called for the use of the physically-based Penman-Monteith PET method to estimate PDSI. Here, we present a user-friendly PDSI tool that uses the Penman-Monteith method to calculate PET as an input to the PDSI calculations. Comparisons with a global PDSI dataset also estimated using the Penman-Monteith method indicate good spatial correlation. This tool allows users to easily calculate a suite of Palmer drought indices using Penman-Monteith PET for current and future drought projections at any spatial scale. We present a 12-km resolution Penman-Monteith PDSI dataset of the United States, as well as potential applications of its use.

    A novel TEX86-derived sea surface temperature (SST) record was generated from well-dated hemipelagic sediments drilled in Palmer Deep, on the western Antarctic Peninsula continental shelf (ODP Hole 1098B; 64°51.162'S, 64°12.4795'W; 1010 m). Regional surface sediment samples with paired CTD casts are the first to demonstrate the potential utility of the TEX86 proxy in carbonate-poor western Antarctic Peninsula continental margin sediments. Average down core TEX86-derived temperatures at Site 1098 ranged between 1 and 6°C during the Holocene (0-12 ka). A long-term cooling of 3°C between 12 and 0 ka is punctuated by millennial scale temperature variability. While the absolute SST values and associated uncertainties should be regarded with caution until a more robust calibration of the TEX86 proxy at colder (0-5°C) temperatures emerges, both the long term and millennial scale variations in ODP Site 1098 TEX86 derived SSTs are consistent with temperature trends observed regionally (in both ice and marine sediment cores) and globally distributed Holocene paleoclimate records. The observed linkages suggest atmospheric (via the Southern Hemisphere westerly winds) control over the Holocene hydrography of Palmer Deep.

    Besides its traditional activities, the Public Outreach & Education offi ce (POE) of INAF-Osservatorio Astronomico di Brera (Milan, Italy) is carrying out two experiments in informal education for children aged 10 to 13: "The Lord of Rings - the mysterious case of the stolen rings" and "The Olmi-comics". The former is an astronomical role-playing game. Pupils are requested to discover the burglars of the rings of Saturn by hunting for them in an area where they meet actors playing their parts at distances scaled to the ones of the Solar System. The latter is a writing/ drawing workshop. Pupils try to write stories or draw comics about science. While the two projects are rather different both in content and in format, they have a common goal: making pupils live science, mainly astronomy, both with the mind and the body.

    At the end of November 1914 Lord Moulton (1844–1921) became the director of explosives production in the War Office. A 70-year-old jurist may seem an extraordinary choice, but he was an extraordinary man. He was Senior Wrangler at Cambridge, was elected to the Royal Society for research on electricity, and learned about chemistry as a barrister for dye and explosives manufacturers. He assembled an able team of administrators and chemists who designed and managed mammoth new national explosives factories. They could not make enough TNT and picric acid from obtainable precursors, so Moulton persuaded the reluctant armed services to adopt mixtures of TNT and ammonium nitrate, which enabled them to make even more than was needed. In mid-1915 they moved to the new Ministry of Munitions, where they also became responsible for fertilizers and poison gases. In 1917 they produced explosives at a higher rate than was attained in World War II. PMID:24921109

    Background: Parikartika resembles fissure-in-ano which is very common among all ano-rectal disorders. In Ayurvedic texts, Parikartika is described as a complication of Vamana and Virechana as well as complication of Atisara. Ksharasutra was proved successful in the management of fistula-in-ano, piles, and there is a need to try its efficacy in fissure-in-ano. Aim: To evaluate the role of Ksharasutra suturing (KSS) in fissure bed in chronic fissure-in-ano. Materials and Methods: Total 100 patients of chronic fissure-in-ano were selected and randomly divided into two groups (50 in each group). In group-A, patients were undergone by KSS; while in patients of Group-B Lord's anal dilatation followed by KSS was done under spinal anesthesia. The KSS was done once and after slough out of Ksharasutra, the wound was treated for 4 weeks and assessment of the result was done on the basis of gradation adopted. Results: The pain relief on 14th day in Group-A was 86% while in Group-B 100% was observed. As on 7th day in Group-A, oozing was stopped in 68% patients, while in Group-B, oozing was stopped in 82% patients. On 21st day, Group-B showed more healing (85%) as compared to Group-A (69%). In this study 68% of patients were cured. Conclusion: In Group-B (KSS with Lord's anal dilatation) patients were cured early as compared to patients of Group-A (KSS alone). PMID:25558158

    Water resources are vital to sustaining ecosystem services, energy and food supplies, and industrial processes. Competition for water resources is likely to intensify as the population increases, economy grows, and land develops. Drought events intensify water scarcity, and recent events in many countries, including the United States (US), Great Britain, and Sri Lanka, highlight how important it is to provide meaningful context to water planners and managers. Palmer's drought indices - Z Index, Palmer Drought Severity Index (PDSI), and Palmer Hydrological Drought Index (PHDI) - are widely used and accepted by scientists and policy makers in the US to understand drought and manage water resources. Drought index values at the climate division scale are available, but a transparent calculation tool at multiple spatial and temporal scales is not readily available. Moreover, a close look at the development of the indices reveals a number of subjective calculation methods and regionally biased factors. For researchers studying areas with overlapping climate divisions, performing international research, or working with limited, site-specific data, the ability to control and modify calculations is desired. This research presents a transparent tool for calculating Palmer's drought indices. We use the Apalachicola-Chattahoochee-Flint (ACF) River Basin, located in the southeastern US, as our case study to explore and evaluate the sensitivity of Palmer's indices to temperature and precipitation anomalies, calibration periods, and other index components. The ACF has suffered two major droughts (2007 and 2012) in the past five years and supports multiple demand-side sectors - agriculture in Georgia, public and recreational supply for the Atlanta metropolitan area, hydroelectric power in Alabama, tri-state navigation, and ecosystem services. We show how the PDSI varies in response to changes in precipitation, calibration period, and a number of other variables. The aim of the work is to make this easily used tool available to help professionals who work toward facilitating water management and reducing water conflicts in the future.

    Herbicide efficacy is known to be influenced by temperature, however, underlying mechanism(s) are poorly understood. A marked alteration in mesotrione [a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor] efficacy on Palmer amaranth (Amaranthus palmeri S. Watson) was observed when grown under low- (LT, 25/15 °C, day/night temperatures) and high (HT, 40/30° C) temperature compared to optimum (OT, 32.5/22.5 °C) temperature. Based on plant height, injury, and mortality, Palmer amaranth was more sensitive to mesotrione at LT and less sensitive at HT compared to OT (ED50 for mortality; 18.5, 52.3, and 63.7 g ai ha-1, respectively). Similar responses were observed for leaf chlorophyll index and photochemical efficiency of PSII (Fv/Fm). Furthermore, mesotrione translocation and metabolism, and HPPD expression data strongly supported such variation. Relatively more mesotrione was translocated to meristematic regions at LT or OT than at HT. Based on T50 values (time required to metabolize 50% of the 14C mesotrione), plants at HT metabolized mesotrione faster than those at LT or OT (T50; 13, 21, and 16.5 h, respectively). The relative HPPD:CPS (carbamoyl phosphate synthetase) or HPPD:?-tubulin expression in mesotrione-treated plants increased over time in all temperature regimes; however, at 48 HAT, the HPPD:?-tubulin expression was exceedingly higher at HT compared to LT or OT (18.4-, 3.1-, and 3.5-fold relative to untreated plants, respectively). These findings together with an integrated understanding of other interacting key environmental factors will have important implications for a predictable approach for effective weed management.

    Fishes were collected from seamounts and insular slopes of the northern Tasman and southern Coral Seas in the environs of the Reinga Ridge, Norfolk Ridge and Lord Howe Rise, at depths ranging from 49 to 1927 m. A total of 348 demersal fish species in 99 families, which were collected from 135 samples taken with a variety of sampling gear, greatly improved taxonomic knowledge of this poorly known area. Twenty five percent of the fish sampled are considered to be potentially new species. Relatively high levels of regional endemicity and diversity are attributed to geological history, and the complexity of contemporary climatology, hydrography and habitat diversity of the region. Fish assemblages were highly structured by depth, but across regions, deep-water fish faunas showed stronger taxonomic affinities than shallower faunas. Although less pronounced, spatial differences pointed towards distinct faunas between the southern and northern parts of the area. The distribution patterns and affinities to regions adjacent to the survey area indicate that (1) the fish fauna on the Lord Howe Rise near Lord Howe Island and further north is distinct from the rest of the survey regions, and exhibits eastern Australian and northern (Coral Sea) affinities, (2) the Northern Norfolk Ridge fauna is distinct from the other regions and has strong affinities with New Caledonia, (3) fishes on the Southern Norfolk Ridge, Western Norfolk Ridge and Lord Howe Plateau have more shared species compared to the other regions indicating a high level of connectedness and affinities with New Zealand fauna, and (4) some species have a wide distribution along the Norfolk Ridge providing a possible deepwater pathway between New Caledonia and New Zealand. Survey data is also useful for assessing the regions' conservation values by identifying rare or unusual components of the fauna, those with very limited distributions, those with low productivity that may be vulnerable to human disturbance (fishing, mining), and for defining bioregions.

    Lord and Wingersky's (Appl Psychol Meas 8:453-461, 1984) recursive algorithm for creating summed score based likelihoods and posteriors has a proven track record in unidimensional item response theory (IRT) applications. Extending the recursive algorithm to handle multidimensionality is relatively simple, especially with fixed quadrature because the recursions can be defined on a grid formed by direct products of quadrature points. However, the increase in computational burden remains exponential in the number of dimensions, making the implementation of the recursive algorithm cumbersome for truly high-dimensional models. In this paper, a dimension reduction method that is specific to the Lord-Wingersky recursions is developed. This method can take advantage of the restrictions implied by hierarchical item factor models, e.g., the bifactor model, the testlet model, or the two-tier model, such that a version of the Lord-Wingersky recursive algorithm can operate on a dramatically reduced set of quadrature points. For instance, in a bifactor model, the dimension of integration is always equal to 2, regardless of the number of factors. The new algorithm not only provides an effective mechanism to produce summed score to IRT scaled score translation tables properly adjusted for residual dependence, but leads to new applications in test scoring, linking, and model fit checking as well. Simulated and empirical examples are used to illustrate the new applications. PMID:25233839

  5. Myth smashers, myth makers: (re)visionary techniques in the works of Paula Gunn Allen, Gloria Anzaldúa and Audre Lorde.

    This paper examines the revisionist mythmaking strategies employed by three lesbian-feminist writers of color: Paula Gunn Allen (Laguna/Sioux/Lebanese/Scottish), Gloria Anzaldúa (Chicana tejana), and Audre Lorde (Caribbean/African/American). By incorporating creatrix figures such as the West African Mawulisa, the pre-Aztec Coatlicue, and the Laguna Pueblo Spider Old Woman/Thought Woman into their works, they challenge the cultural stereotypes that silence women of color by denying their access to language. Their use of nonwestern mythic material destabilizes monolithic definitions of (white heterosexual) female identity, yet their mythmaking goes beyond this challenge to hegemonic concepts of (white) womanhood. As they replace the Judeo-Christian world-view with modes of perception drawn from Native American, Chicana, and African mythic traditions, they offer a far-reaching critique of western culture's binary structures. By displacing the boundaries between inner/outer, subject/object, spirit/matter, and other dichotomous terms, the new myths they create provide radical alternatives to the existing social structures.

    This article aims to understand how formerly abducted young mothers mediate the social integration of their children conceived of forced marriage and sexual violence within the Lord's Resistance Army (LRA) in northern Uganda. Interviews and photographic methods were used in six Internally Displaced Persons Camps in northern Uganda. This article draws on data derived from ten mothers of thirteen children who were conceived in the LRA, five boys and eight girls. The analytic approach used was Interpretive Phenomenological Analysis (Smith & Osborn, 2008). The analysis identified turning points of sites of action where young formerly abducted mothers used diverse strategies to support the reintegration of their children born or conceived within the LRA. Six key turning points are identified, these are (a) participating in rituals and ceremonies, (b) naming, (c) adapting to changing family structures, (d) responding to discrimination against boys (e) managing disclosure and (f) sharing positive memories and identities. Formerly abducted young mothers mediate the social integration of their children by engaging in strategies to support and foster their wellbeing and social relationships. However, the contexts in which they are operating are highly constrained and the relational identities of children born in the LRA are fluid and potentially insecure within communities of return. Implications for policy and programming are discussed. PMID:26671833

    Reef-building corals are extremely sensitive to changing temperature regimes, such that sustained increases in ocean temperatures are generally expected to have negative effects on coral growth and survivorship. At high-latitude reefs, however, projected increases in ocean temperature may actually increase coral growth (relaxing constraints imposed by cool winter temperatures), though this will depend upon on the rate and extent of declines in aragonite saturation, which is already much lower at high latitudes. This study quantified linear extension rates of six scleractinian corals, Acropora yongei, Isopora cuneata, Pocillopora damicornis, Porites heronensis, Seriatopora hystrix, and Stylophora pistillata, at Lord Howe Island in 2010/11. Contemporary growth rates were compared to equivalent data collected in 1994/95. There was marked interspecific variation in growth rates, with A. yongei growing almost twice the rate of all other species. Temporal changes in annual growth also varied among species. Growth rates of both A. yongei and Pocillopora damicornis were 30 % of that recorded in 1994/95. However, growth rates of Porites heronensis had not changed. Declines in the growth rates of these branching species may be attributable to declines in aragonite saturation or increases in summertime temperatures above limits for optimal growth, but either way it appears that climate change is having negative effects on corals, even at subtropical locations.

    Characterizing a rare disease diagnosis for a given patient is often made through expert’s networks. It is a complex task that could evolve over time depending on the natural history of the disease and the evolution of the scientific knowledge. Most rare diseases have genetic causes and recent improvements of sequencing techniques contribute to the discovery of many new diseases every year. Diagnosis coding in the rare disease field requires data from multiple knowledge bases to be aggregated in order to offer the clinician a global information space from possible diagnosis to clinical signs (phenotypes) and known genetic mutations (genotype). Nowadays, the major barrier to the coding activity is the lack of consolidation of such information scattered in different thesaurus such as Orphanet, OMIM or HPO. The Linking Open data for Rare Diseases (LORD) web portal we developed stands as the first attempt to fill this gap by offering an integrated view of 8,400 rare diseases linked to more than 14,500 signs and 3,270 genes. The application provides a browsing feature to navigate through the relationships between diseases, signs and genes, and some Application Programming Interfaces to help its integration in health information systems in routine.

  9. The Lord of Rings - the mysterious case of the stolen rings: a critical analysis of an informal education activity

    "The Lord of Rings - the mysterious case of the stolen rings" is a live astronomical role-playing game for kids aged 10 -13 [1]. Its goal is to introduce them to some of the main topics of the Solar System: a) the role of gravity; b) the distribution of mass & light; c) the effects of rotation; d) the distribution of water. The game was held at several Science Festival in Italy (Perugia, Genova, Fiorano, Bologna) obtaining great success. Teams of about 6-8 members are introduced to Mr Schioppanelli, the astro-detective of the town (the name is a pun: it reminds Schiaparelli, the famous italian astronomer, and it is a slang expression meaning "ring-breaker"). Mr Schioppanelli has his office in an "gastronomical astronomical observatory", known as The Red Giant Pizzeria. Schioppanelli informs the kids that a mysterious Centaur succeded in stealing the rings of Saturn. The partecipants are appointed astro-detectives incharge and asked to find the rings by browsing around the Solar System, which is scaled so as to fit the town historical centre or a pedestrian area, going from the Sun to Saturn or beyond, depending on the actual area at disposal. Great care must be taken allowing children playing only in a car-free area of the town. At the right scaled distances, the partecipants meet characters playing as the various planets. The kids can talk to them after solving a riddle, obtaining useful informations. A special characters play as a comet, timely going in and out of the inner solar system. The teams can also talk to some shepherdmoons of the rings. They easily discover that the rings were totally destroyed by the Centaur: a real disaster! They are also suggested to gather the necessary ingredients (gravity, light, rotation, inclination, dust and water, represented by simple objects like apples, spinning tops and so on) to rebuild the rings. The kids can buy the ingredients from different planets: every planet has ingredients in quantities which are proportionate to the real physical properties of that celestial object. After collecting the ingredients, they must carry them to the "The Red Giant" and indicate their best recipe to Mr Schioppanelli. Depending on the recipe, rings can be too strict or too luminous or too fast rotating and so on. The winning group is the one which prepares the best recipe to cook the rings in the smallest amount of time. After introducing this specific (and mysterious) game, we analyze the advantage-disadvantage ratio of such an activity, which is as funny as dispersive [2]. The key expression of the whole activity is, of course, "informal education". But, as a best practice result, we organize also 1 or 2 very simple laboratories about the solar system before playing the game. One of these, called The Olmicomics, allows the pupils to understand the dimensions of the planets with respect to their distances, providing them the correct introduction to "The Lord of Rings". The pupils are simply requested to pone the planets in a correct scale on a map of the city where they live. Then we coherently calculate together dimension of the Solar System planets and the Sun, according to the scale they chose. The second activity provide the pupils hints about the physical properties of the planets, touching the points a)-d) listed above. We believe this two-faces strategy is a quite effective tool for an education suited to our target group. They really do things, touch things, use their own body as a meter to understand distances and physical properties as the gravitational force. In the meanwhile, they are also asked to think about what they are doing, to make calculation and to build a representation of the Solar System by numbers, turning it into a visual representation only after their calculation. And, finally, to play with all these conceipts.

  10. Returning home: forced conscription, reintegration, and mental health status of former abductees of the Lord's Resistance Army in northern Uganda

    Background Since the late 1980s, the Lord's Resistance Army (LRA), a spiritualist rebel group in northern Uganda, has killed and mutilated thousands of civilians and abducted an estimated 52,000 to 75,000 people to serve as soldiers, porters, and sex slaves for its commanders. This study examines the types of violence to which former abductees have been exposed and the extent to which these acts have affected their psychological well-being. Methods This is a cross-sectional study of 2,875 individuals selected through a multi-stage stratified cluster sampling design conducted in 8 districts of northern Uganda. Multivariate logistic regressions were performed with symptoms for Post-traumatic Stress Disorder (PTSD) and depression as the main outcome measures. Results One-third of the respondents (33%) self-reported having experienced abduction (49% among the Acholi, the largest tribal group in northern Uganda). Over half (56%) of all the respondents and over two-thirds of those who experienced abduction met the criteria for symptoms of post-traumatic stress disorder (PTSD). Multivariate analysis shows that several factors increased the risk of former LRA abductees developing symptoms of PTSD. These factors included gender (females were more susceptible than males), being a member of the Acholi ethnic group, participating in or witnessing a cumulative number of traumatic events, and encountering difficulties re-integrating into communities after abduction. Factors associated with increased risk of meeting criteria for symptoms of depression included older age of males at the time of abduction, lower score on social relationship scale, high incidence of general traumatic event exposure, high incidence of forced acts of violence, and problems reintegrating into communities after abduction. Conclusion Abduction and forced conscription of civilians has affected the psychological well-being of a significant number of northern Ugandans. The sources of psychological trauma are multiple, ranging from witnessing to being forced to commit violent acts, and compounded by prolonged exposure to violence, often for months or years. Community-based mental health care services and reintegration programs are needed to facilitate the reintegration of former abductees back into their communities. PMID:19445689

    For the Danube lower basin, 27 stations relatively evenly distributed in Romania, were considered. Based on average monthly temperatures, the total monthly rainfall and available water capacity (AWC), four indices Palmer PDSI, PHDI, WPLM, and ZIND, were calculated. The four indices Palmer have both common features and differences, but overall help us to analyze the variability of drought or excessive moisture for the area studied. Also, an index easier to estimate was calculated, which depends only on the temperatures and precipitation normalized (TPP). The analyzes were performed separately for each season from a 61-year period (1931-1998). For each of the four indices Palmer and for TPP index, decompositions in the empirical orthogonal functions (EOFs) were carried out. For a feature overview of the state of drought or excessive moisture we achieved decompositions in the multivariate EOFs (MEOF) of the four indices Palmer. In all analyzes we used only the first temporal component, namely the principal component (PC1). Limits of variation of these indices, the change points which separating the dry periods and relatively wet periods and quasi-periodicities were highlighted for each season. We tested the influence of large-scale atmospheric circulation by means of pressure index, which we named Greenland Balkan Oscillation Index (GBOI), similar to the NAO index, but GBOI is more efficient for the studied area. The GBO index has a clear influence on the variation of drought indices in winter, especially for the overall index expressed by PC1-MEOF. Regarding the influence of other extra atmospheric factors on the occurrence dry periods or excessively wet periods, this influence has been tested considering the Wolf numbers and Kp index. From testing the influence of geomagnetic activity through the correlative analysis using Kp index, statistically significant results (95%) were obtained only for winter season for PC1-MEOF and PC1-TPP. Also, for winter, power spectra reveal quasi-periodicities of 7-8 years found in the PC1-TPP series also in the Kp. Regarding solar activity, expressed by the Wolf numbers, its influence is significant only for the spring season, highlighted by a cycle of approximate of 11-year in the principal component (PC1) of the drought estimated by temperatures and precipitation (TPP) in Danube lower basin. These preliminary results will be completed with new investigations for the entire Danube basin, considering longer time series and a discriminate analysis by taking into consideration the occurrence of the maxima and minima in the solar/ geomagnetic activity.

    In India, Cannabis Indica has been used for literally thousands of years in the worship of the god Shiva. Cannabis is used in an orally administered form called bhang which can be either the wet resinous leaves formed into pills of a drink made of milk, cannabis, and various spices consumed by worshipers of Shiva on festival days or by smoking the flowering buds of cannabis-a practice generally reserved for holy men who dedicate their lives to ascetic practice and the worship of Shiva. This practice is codified in the Vedas as well as in legends about the origin of cannabis and its relationship to Shiva. PMID:22742944

    The loss of life and property from drought events has forced society to focus on the development of reliable early warning systems which may enable farmers and other stakeholders to correctly and timely adapt to the expected impacts of climatic hazard. However, a scientific approach to a reliable early warning system for a region requires, among others, characterisation of drought events in the region in terms of duration, magnitude, intensity and frequency using standard drought indices. Therefore, the objective of this study was to identify and characterise drought events in the Modder River basin, central region of South Africa, using a self-calibrated Palmer's Drought Severity Index (sc-PDSI). Attempts were also made to establish a relationship between meteorological and hydrological drought events in the region. During the period of analysis, the total number of drought episodes identified in the study area ranged between eight and sixteen. It was found that the most severe drought episodes occurred during the period 1992-1995 followed by the period 1982-1987. Results of analysis of seasonal drought events in one of the quaternary catchments (C52A) revealed that peak drought events during the three summer months (November, December and January) occurred in the area in 1993. However, in terms of event magnitude and intensity, the worst drought events were recorded during the period December 1982-July 1987, followed by the event that ensued during December 1989-September 1995. Results of analysis of decadal variation of drought events showed that the number of extreme and moderate drought events recorded in the catchment showed statistically significant increasing trends during the five decades at 5 % significance level. Moreover, spectral analysis of sc-PDSI time series in the region identified periodicities in the time series ranging from 6 years (C52E) to 16 years (C52K). In terms of the spatial extent of extreme drought events, the maximum areal coverage (91 %) was recorded in November 1998, followed by December 1998 and December-January 1999 (43 %). Analysis of the relative frequency of droughts of varying categories revealed that extreme drought events were most prevalent in the C52E (2.72 %) quaternary catchment, followed by C52C (2.21 %). The study also found an average lag time of 10 months between the onsets of meteorological and hydrological drought events in the region.

  15. Backscattering enhancement on spheroid-shaped hydrometeors: Considerations in water and ice particles of uniform size and Marshall-Palmer distributed rains

    A second-order scattering theory is derived for uniformly oriented spheroidal hydrometeors with a general drop size distribution in a single layer. Effects of backscattering enhancement are evaluated for a nadir pointing radar with a finite beam width at millimeter wave frequencies. Spheroids of uniform size are first studied to characterize the deviations from the spherical theories. For water spheroids, the difference between the cross term (backscattering enhancement term) and the ladder term (conventional multiscattering term) becomes larger as the spheroids deviate from the spherical shape. On the contrary, for ice spheroids, this difference is negligible. Marshall-Palmer distributed rains with Pruppacher-Pitter-form drops are studied using the spheroidal approximation. The results confirm the validity of the spherical approximation used in the preceding works within the accuracy limit of measurement. In the Marshall-Palmer distributed rains, the second-order scattering effect becomes serious as the footprint radius increases. Hence the second-order scattering is to be taken into account for accurate measurement of hydrometeor reflectivity for a spaceborne radar because of its large footprint radius.

    This year marks the 20th anniversary of the launch of Journal of Physics: Condensed Matter in 1989. The journal was formed from the merger of Journal of Physics C: Solid State Physics and Journal of Physics F: Metal Physics which had separated in 1971. In the 20 years since its launch, Journal of Physics: Condensed Matter has more than doubled in size, while raising standards. Indeed, Journal of Physics: Condensed Matter has become one of the leading scientific journals for our field. This could not have occurred without great leadership at the top. No one has been more responsible for this growth in both size and quality than our Senior Publisher, Richard Palmer. Richard first started work at IOP in March 1971 as an Editorial Assistant with J. Phys. B After a few months, he transferred to J. Phys.C The following year, the Assistant Editor of J. Phys. C, Malcolm Haines, left suddenly in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of J. Phys. C, before being given the job of Assistant Editor permanently. Since J. Phys. C and J. Phys. F re-merged to form Journal of Physics: Condensed Matter, Richard gradually shed his other journal responsibilities, except for Reports on Progress in Physics, to build up Journal of Physics: Condensed Matter. He has worked closely with four Editors-in-Chief of J. Phys. C and five of Journal of Physics: Condensed Matter. When Richard announced his retirement this past winter, we met it with a great deal of both happiness and sadness. Of course, we are happy that he is going to be allowed to enjoy his retirement, but we remain very sad to lose such a valuable member of our team, especially the one who had provided the heart and soul of the journal over its 20 years. We will be able to rely upon the team which Richard ably trained as we go into the future. The Executive Board decided to do this special issue, both to commemorate the 20th year of Journal of Physics: Condensed Matter and to honour Richard for his long years of service to IOP Publishing and Journal of Physics: Condensed Matter. This issue is dedicated to Richard for his many years of work and friendship with the journal board that has seen a great many changes over the years. This issue covers a very wide range of topics, since we approached all current and past members of the various boards of Journal of Physics: Condensed Matter in seeking papers for this special issue. The response has been very positive and this will be one of our larger special issues. The desire to honour Richard is widespread among these various boards, so that we have been almost overwhelmed with submissions, although many who wished to contribute could not because of other obligations. We hope that you, the readership, will enjoy these articles.

    We developed a ring-width chronology of teak ( Tectona grandis L.) from a moisture stressed area in Maharashtra, India. Bootstrapped correlation analysis indicated that moisture index (MI) and Palmer Drought Severity Index (PDSI) showed better performance rather than same year rainfall over the region. Tree-ring variations were most correlated positively with PDSI during different seasons compared with MI. Significant strong positive correlation with MI, and negative association with temperature and potential evapotranspiration (PET) were found during previous and current year post-monsoon (ON). This study shows that the moisture availability during the post-monsoon of the previous year has a significant role in the development of annual growth rings. The reconstructed previous year post-monsoon (-ON) moisture index for the period 1866-1996 indicates 3.5 and 29.3 years periodicities.

    There are substantial differences among taxonomic groups in their capacity to reach remote oceanic islands via long-distance overwater dispersal from mainland regions. Due to their permeable skin and intolerance of saltwater, amphibians generally require human-assisted dispersal to reach oceanic islands. Several Litoria frog species have been introduced to remote islands throughout the Pacific Ocean region. Lord Howe Island (LHI) is an oceanic island that lies approximately 600 km east of the Australian mainland and has a diverse, endemic biota. The bleating tree frog (Litoria dentata) is native to mainland eastern Australia, but was accidentally introduced to LHI in the 1990s, yet its ecology and potential impact on LHI has remained unstudied. We used a mitochondrial phylogeographical approach to determine that L. dentata was introduced from the Ballina region in northeastern New South Wales. The founding population was likely accidentally introduced with cargo shipped from the mainland. We also completed the first detailed investigation of the distribution, ecology and habitat use of L. dentata on LHI. The species is widespread on LHI and is prevalent in human habitat, cattle pasture and undisturbed forest. We discuss the potential impact of introduced Litoria species on Pacific islands and outline what biosecurity protocols could be implemented to prevent the introduction of further amphibian species to the ecologically sensitive oceanic area.

    Variability in the temporal-spatial distribution and abundance of zooplankton was documented each summer on the Palmer Long-Term Ecological Research (LTER) grid west of the Antarctic Peninsula between Anvers and Adelaide Islands during a 12-yr time series. Oblique tows to 120 m with a 2×2 m fixed-frame net were made at about 50 stations each January/February between 1993 and 2004. The numerically dominant macro- and mesozooplanktonic species >2 mm included three species of euphausiids ( Euphausia superba, Antarctic krill; Thysanoëssa macrura; Euphausia crystallorophias, ice krill), a shelled pteropod ( Limacina helicina), and a salp ( Salpa thompsoni). Life cycles, life spans, and habitat varied among these species. Abundance data from each year were allocated to 100 km by 20 km (alongshore by on/offshore) grid cells centered on cardinal transect lines and stations within the Palmer LTER grid. The long-term mean or climatology and means for each year were used to calculate annual anomalies across the grid. Principal components analysis (PCA) was used to analyze for patterns and trends in the temporal-spatial variability of the five species. Questions included whether there are groups of species with similar patterns, and whether population cycles, species interactions or seasonal sea-ice parameters were correlated with detected patterns. Patterns in the climatology were distinct, and matched those of physical parameters. Common features included higher abundance in the north than in the south, independent of the cross-shelf gradients, and cross-shelf gradients with higher abundance either inshore ( E. crystallorophias) or offshore ( S. thompsoni). Anomalies revealed either cycles in the population, as episodic recruitment in Antarctic krill, or changes in anomaly pattern between the first and second half of the sampling period. The 1998 year, which coincided with a rapid change from a negative to a positive phase in the SOI, emerged as a year with either significant anomalies or that marked a change in anomaly patterns for different species. PCA analysis showed that the pattern of cumulative variance with increasing number of modes was distinctly different for shorter-lived versus longer-lived species; the first mode accounted for nearly 50% of the variance in the shorter-lived species and less than 25% in the longer-lived species. This suggested that the mechanisms driving variability in the temporal-spatial distribution of the shorter-lived, more oceanic species were less complex and more direct than those for the longer-lived euphausiids. Evidence from both the anomaly plots and the trend analysis suggested that salps have been more consistently present across the shelf from 1999 to present, and that the range of L. helicina has been expanding. With shorter life spans, these two species can respond more quickly to the increasing heat content on the shelf in this region. The cross-correlation analysis illustrated the negative correlation between salps and ice retreat and the number of ice days, and the positive correlation between the presence of ice krill and the day of ice retreat. These results suggest that for these species, several environmental controls on distribution and abundance were linked to seasonal sea-ice dynamics.

    Cost-effective and reliable vegetation monitoring methods are needed for applications ranging from traditional agronomic mapping, to verifying the safety of geologic injection activities. A particular challenge is defining baseline crop conditions and subsequent anomalies from long term imagery records (Landsat) in the face of large spatiotemporal variability. We develop a new method for defining baseline crop response (near peak growth) using the normalized difference vegetation index (NDVI) from 26 years (1986-2011) of Landsat data for 400 km2 surrounding a planned geologic carbon sequestration site near Jacksonville, Illinois. The normal score transform (yNDVI) was applied on a field by field basis to accentuate spatial patterns and level differences due to planting times. We tested crop type and soil moisture (Palmer crop moisture index (CMI)) as predictors of expected crop condition. Spatial patterns in yNDVI were similar between corn and soybeans - the two major crops. Linear regressions between yNDVI and the cumulative CMI (CCMI) exposed complex interactions between crop condition, field location (topography and soils), and annual moisture. Wet toposequence positions (depressions) were negatively correlated to CCMI and dry positions (crests) positively correlated. However, only 21% of the landscape showed a statistically significant (p < 0.05) linear relationship. To map anomalous crop conditions, we defined a tolerance interval based on yNDVI statistics. Tested on an independent image (2013), 63 of 1483 possible fields showed unusual crop condition. While the method is not directly suitable for crop health assessment, the spatial patterns in correlation between yNDVI and CCMI have potential applications for pest damage detection and edaphological soil mapping, especially in the developing world.

    This report discusses the procedures and methods used to measure total carbon dioxide (TCO2), total alkalinity (TALK), and partial pressure of CO2 (pCO2) at hydrographic stations during the cruise of research vessel (R/V) Nathaniel B. Palmer in the Southern Indian Ocean on the S04I Section as a part of the Joint Global Ocean Flux Study (JGOFS)/World Ocean Circulation Experiment (WOCE). The carbon-related measurements were sponsored by the U.S. Department of Energy (DOE). The expedition started in Cape Town, South Africa, on May 3, 1996, and ended in Hobart, Australia, on July 4, 1996. Instructions for accessing the data are provided. The TCO2 was measured in discrete water samples using the Lamont-Doherty Earth Observatory (LDEO) coulomteric system with an overall precision of ±1.7 μmol/kg. TALK was determined by potentiometric titration with an overall precision of ±1.7 μmol/kg. During the S04I cruise pCO2 was also measured using the LDEO equilibrator-gas chromatograph system with a precision of 0.5% (including the station-to-station reproducibility) at a constant temperature of 4.0ºC. The R/V Nathaniel B. Palmer S04I data set is available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center. The NDP consists of the oceanographic data files and this printed documentation, which describes the contents and format of all files as well as the procedures and methods used to obtain the data.

  6. Highly Variable Holocene Antarctic Climate: A High-Resolution Marine Geochemical Record of Surface and Export Production, Terrigenous Provenance, and Terrigenous Accumulation from the Palmer Deep, West Antarctic Peninsula.

    The Antarctic Peninsula is an ideal region to investigate climate change at decadal to millennial timescales due to its location in one of the earth's most dynamic climate systems. We have targeted the geochemical sedimentary record of ODP Site 1098 in the Palmer Deep to investigate changes in Holocene glacial evolution and oscillations in the Circumpolar Deep Water as traced by terrigenous provenance, terrigenous accumulation, nutrient utilization, and surface and export production. More than 50 meters of laminated diatomaceous muds, oozes, and muddy diamictons were recovered from the Palmer Deep, comprising the first, high-resolution, continuous Holocene sediment record from the Antarctic continental margin. We report on a synthesis of trace and major element, stable isotope, and C/N geochemistry on samples collected at a temporal resolution ranging from ~8 to ~50 years. We analyzed Si, Al, Ti, P, Ba, biogenic opal, organic C and N, and organic 13C/12C and 15N/14N isotopic ratios every 2.5 to 10 cm downcore. A series of sequential extractions were completed on a subset of samples to better constrain the elemental distribution within the different components of the sediment. Our chronology is based on 36 AMS radiocarbon dates. Biogenic opal, Corg, and P accumulation rates all increase ~2,000 years B.P., reaching a maximum ~5,500 to 7,000 years B.P. Opal concentrations are less variable, yet indicate that biosiliceous production increased during the mid-Holocene. 13C/12C in bulk organic matter are high (with values similar to ice-edge bloom products) ~4500 to 7000 years B.P., signifying stronger diatom bloom events during the mid-Holocene. Prior to ~3000 years B.P., delta15N was lower for ~2,000 years, resulting from less complete utilization of photic zone nitrate. The Al/Ti ratio indicates a change in terrigenous composition ~3500 years B.P. indicating a change in source, weathering style, and/or intensity. All tracers of productivity and terrigenous provenance exhibit significant variance at periods of ~400, 200, 140, and 70 years. Cross-spectral analysis of Al/Ti vs Al accumulation show that these two parameters are in phase with each other at the 400, 200, and 140 year periods, suggesting that changes in terrigenous provenance are concurrent with changes in terrigenous accumulation. Although the mechanisms forcing mid-Holocene enhancements in productivity and terrigenous supply remain unclear, candidates include greater glacial and sea-ice freshwater influences, reduced wind shear, or changing oceanographic frontal positions. A possible external forcing parameter is solar irradiance, possibly mediated through variability in the polar vortex.

    Every-Palmer and Howick suggest that evidence-based medicine (EBM) is failing in its mission because of contamination of research by manufacturer and researcher-motivated bias and self-interest. They fail to define that mission and to distinguish between the EBM movement and the research enterprise it was developed to critique. An educational movement, EBM accomplished its mission to simplify and package clinical epidemiological concepts in a form accessible to clinical learners. Its wide adoption within educational circles fostered critical literacy among several generations of practitioners. Illumination of bias, subterfuge and incomplete reporting of research has been a strength of EBM. Increased uptake and use of clinical research within the health care system properly defines the failing mission that eludes Every-Palmer and Howick. Responsibility for failure to make progress towards its achievement is shared by virtually all relevant streams within the system, including policy, clinical guideline development, educational movements and the development of approaches to evidence synthesis. Discordance between the epistemological premises pervading today's research and health care community and the complex social processes that ultimately determine research use constitutes an important factor that must be addressed as part of a remedy. Enhanced emphasis on and demonstration of alternative approaches to research such as realism and realist synthesis and the momentum towards development of a learning health care system hold promise as guideposts for the rapidly evolving health care environment.

    The Answers in Genesis Creation Museum opened in May of 2007. During the opening day, a loosely affiliated group of scientists joined in a Rally for Reason as they termed it to protest the museum's potential effect on science in the United States. This paper discusses ethnographic data collected before and during the rally. Scientist narratives disclose the rationale for their participation at the rally, unpacking their hopes, fears and social ideals vis-à-vis their perception of the Museum's impact. With these ideals, I discuss the lacking discourse between the values of ideal of science literacy, the contested authority of museums and their publics, and a lacking conception of how a valuerationality aligned towards the Museum's message continues to be culturally produced.

    Viscosity coefficient curve fits for neutral gas species are available from many sources. Many do a good job of reproducing experimental and computational chemistry data. The curve fits are usually expressed as a function of temperature only. This is consistent with the governing equations used to derive an expression for the neutral species viscosity coefficient. Ionized species pose a more complicated problem. They are subject to electrostatic as well as intermolecular forces. The electrostatic forces are affected by a shielding phenomenon where electrons shield the electrostatic forces of positively charged ions beyond a certain distance. The viscosity coefficient for an ionized gas species is a function of both temperature and local electron number density. Currently available curve fits for ionized gas species, such as those presented by Gupta/Yos, are a function of temperature only. What they did was to assume an electron number density. The problem is that the electron number density they assumed was unrealistically high. The purpose of this paper is two-fold. First, the proper expression for determining the viscosity coefficient of an ionized species as a function of both temperature and electron number density will be presented. Then curve fit coefficients will be developed using the more realistic assumption of an equilibrium electron number density. The results will be compared against previous curve fits and against highly accurate computational chemistry data.

  1. Lord Kelvin and the Age-of-the-Earth Debate: A Dramatization

    NASA Astrophysics Data System (ADS)

    Stinner, Art; Teichmann, Jürgen

    This is a dramatization of a fictitious debate about the age of the earth that takes place in the Royal Institution, London, England, in the year 1872. The debate is among Sir William Thomson (later Kelvin), T.H. Huxley (Darwin's Bulldog), Sir Charles Lyell, and Hermann von Helmholtz. In 1862 Thomson published his celebrated and widely studied The Secular Cooling of the Earth that raised the post-Darwinian debate of the age of the earth above the level of popular controversy. He entered the debate with all the arrogance of a newly established science of the century, namely the recently drafted laws of thermodynamics. The debate is partly based on a lively exchange of comments and arguments that occurred between T.H. Huxley and William Thomson, starting in 1868, when Thomson addressed the Glasgow Geological Society. This long public discussion also involved the ideas and the work of geologist Charles Lyell and those of the celebrated German physicist Hermann von Helmholtz. The confrontation is between the unyielding physicists and the insecure biologists and geologists who required a much longer time for the age of the earth than the physicists were prepared to give them. However, the debate ends on a conciliatory note, suggesting that perhaps Sir William's storehouse of creation may contain a hereto undiscovered source of energy that is more bountiful than gravitational energy.

    Reproducing measurements of the scattering mean free paths for energetic particles propagating through the solar system has been a major problem in space physics. The pioneering work of Bieber et al. (1994) provided a theoretical explanation of such observations, which, however, was based on assumptions such as the questionable hypothesis that quasi-linear theory is correct for parallel diffusion. By employing a hybrid plasma-wave/magnetostatic turbulence model, a test-particle code is used to investigate the scattering of energetic particles. The results show excellent agreement with solar wind observations.

    Reduction in the area and volume of the two polar ice sheets is intricately linked to changes in global climate, and the resulting rise in sea level could severely impact the densely populated coastal regions on Earth. Antarctica is Earth's largest reservoir of glacial ice. Melting of the West Antarctic part alone of the Antarctic ice sheet would cause a sea-level rise of approximately 6 meters (m), and the potential sea-level rise after melting of the entire Antarctic ice sheet is estimated to be 65 m (Lythe and others, 2001) to 73 m (Williams and Hall, 1993). The mass balance (the net volumetric gain or loss) of the Antarctic ice sheet is highly complex, responding differently to different climatic and other conditions in each region (Vaughan, 2005). In a review paper, Rignot and Thomas (2002) concluded that the West Antarctic ice sheet is probably becoming thinner overall; although it is known to be thickening in the west, it is thinning in the north. The mass balance of the East Antarctic ice sheet is thought by Davis and others (2005) to be positive on the basis of the change in satellite-altimetry measurements made between 1992 and 2003. Measurement of changes in area and mass balance of the Antarctic ice sheet was given a very high priority in recommendations by the Polar Research Board of the National Research Council (1986), in subsequent recommendations by the Scientific Committee on Antarctic Research (SCAR) (1989, 1993), and by the National Science Foundation's (1990) Division of Polar Programs. On the basis of these recommendations, the U.S. Geological Survey (USGS) decided that the archive of early 1970s Landsat 1, 2, and 3 Multispectral Scanner (MSS) images of Antarctica and the subsequent repeat coverage made possible with Landsat and other satellite images provided an excellent means of documenting changes in the cryospheric coastline of Antarctica (Ferrigno and Gould, 1987). The availability of this information provided the impetus for carrying out a comprehensive analysis of the glaciological features of the coastal regions and changes in ice fronts of Antarctica (Swithinbank, 1988; Williams and Ferrigno, 1988). The project was later modified to include Landsat 4 and 5 MSS and Thematic Mapper (TM) images (and in some areas Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images), RADARSAT images, aerial photography, and other data where available, to compare changes that occurred during a 20- to 25- or 30-year time interval (or longer where data were available, as in the Antarctic Peninsula). The results of the analysis are being used to produce a digital database and a series of USGS Geologic Investigations Series Maps (I-2600) (Williams and others, 1995; Swithinbank and others, 2003a,b, 2004; Ferrigno and others, 2002, 2005, 2006, 2007, 2008, and in press; and Williams and Ferrigno, 2005) (available online at http://www.glaciers.er.usgs.gov).

  15. FROM THE HISTORY OF PHYSICS: The Einstein formula: E0=mc2. "Isn't the Lord laughing?"

    NASA Astrophysics Data System (ADS)

    Okun, L. B.

    2008-05-01

    The article traces the way Einstein formulated the relation between energy and mass in his work from 1905 to 1955. Einstein emphasized quite often that the mass m of a body is equivalent to its rest energy E0. At the same time, he frequently resorted to the less clear-cut statement of the equivalence of energy and mass. As a result, Einstein's formula E0=mc2 still remains much less known than its popular form, E=mc2, in which E is the total energy equal to the sum of the rest energy and the kinetic energy of a freely moving body. One of the consequences of this is the widespread fallacy that the mass of a body increases when its velocity increases and even that this is an experimental fact. As wrote the playwright A N Ostrovsky "Something must exist for people, something so austere, so lofty, so sacrosanct that it would make profaning it unthinkable."

The large fluence of the flare and the large column density of interstellar dust toward Circinus X-1 make this the largest and brightest set of rings from an X-ray light echo observed to date. By deconvolving the radial intensity profile of the echo with the MAXI X-ray light curve of the flare we reconstruct the dust distribution toward Circinus X-1 into four distinct dust concentrations. By comparing the peak in scattering intensity with the peak intensity in CO maps of molecular clouds from the Mopra Southern Galactic Plane CO Survey we identify the two innermost rings with clouds at radial velocity ? -74 and ? -81 {km} {{{s}}}-1, respectively. We identify a prominent band of foreground photoelectric absorption with a lane of CO gas at ? -32 {km} {{{s}}}-1. From the association of the rings with individual CO clouds we determine the kinematic distance to Circinus X-1 to be {D}{CirX-1}={9.4}-1.0+0.8 {kpc}. This distance rules out earlier claims of a distance around 4 {kpc}, implies that Circinus X-1 is a frequent super-Eddington source, and places a lower limit of {{? }}? 22 on the Lorentz factor and an upper limit of {? }{jet}? 3^\\circ on the jet viewing angle.

    'I have dealt with many different transformations with various periods of time, but the quickest that I have met was my own transformation in one moment from a physicist to a chemist.' Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes? In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the 'Theory of Everything'?

    Egg stasis ('egg-binding', 'post-ovulatory stasis') is a poorly characterized syndrome characterized by an inability of female fish to complete ovulation and to naturally expel mature eggs. Although it occurs in a variety of fish species, no definitive studies of the causation, prevalence, prevention and treatment have been done. The cause of egg stasis appears to be multifactorial to include aspects of a captive environment not suitable for the completion of spawning.

    2000-01-01

    Describes the church involvement of young African American men who have sex with men (MSM). Reports data secured from 76 individual semistructured interviews with men between the ages of 18 and 29 who reported recent sexual behavior with other men in Atlanta and Chicago that revealed high levels of involvement in African American churches and its impact on self-esteem and sexual behavior. Notes that participation in African American churches encourages sexual secrecy and is associated with decreased frequencies of same-sex contacts. Suggests that African American clergy and other church leaders can initiate dialogue with church-going MSM and redirect ministerial efforts to foster inclusive, nurturing religious communities that no longer marginalize these African American men.

    Purpose Most breast cancer survivorship research focuses on the general population of survivors. Scant research investigates the potentially unique experiences of minorities, especially during and after the difficult transition from primary treatment to post-treatment. This qualitative study explored African American breast cancer survivors’ and caregivers’ quality-of-life in the post-treatment period with a focus on social and spiritual well-being. Methods Participants included a convenience sample of African American women with stage I-III breast cancer (N=23) who completed treatment 6–24 months before enrollment. Primary caregivers (N=22) included friends, spouses and other family members (21 complete dyads). Participants completed separate semi-structured telephone interviews. Template analysis was used to evaluate themes related to religiousness and spirituality, both across and within dyads. Results After treatment, religiousness and spirituality played a major role in both survivors’ and caregivers’ lives by: 1) providing global guidance, 2) guiding illness management efforts and 3) facilitating recovery. Participants described a spiritual connectedness with God and others in their social networks. Dyad members shared the goal of keeping a positive attitude and described positive growth from cancer. Few future concerns were expressed due to the belief that survivors were healed and “done” with cancer. Beyond practical and emotional support, provision of spiritual assistance was common. Conclusions Results highlight the principal, positive role of religiousness and spirituality for African American breast cancer survivors and caregivers after treatment. Findings emphasize the need to assess the importance of religious and spiritual beliefs and practices, and if appropriate, to provide resources that promote spiritual well-being. PMID:24578149

  8. Commit your works to the Lord, and your thoughts shall be established (Prov. 16:3). Inter-stable control systems

    NASA Technical Reports Server (NTRS)

    Vonpragenau, George L.

    1987-01-01

    Algebraic structures are discussed for control systems that maintain stability in the presence of resonance uncertainties. Dual algebraic operations serve as elementary connections that propagate the stability of inter-stable subsystems. Frequency responses within complex half-planes define different types of inter-stability. Dominance between incompatible types is discussed. Inter-stability produces sufficient but unnecessary stability conditions, except for conservative systems where the conditions become also necessary. Multivariable systems, colocation of actuator and sensor, and virtual colocation are treated. Instead of passivity, inter-stability relates stability to the mapping of poles and zeros by transfer functions and transfer matrices. Inter-stability determines stability on the subsystem level, is less complex even for multivariable systems, adds design flexibility, and relaxes the dynamic data problem of large systems such as space stations.

    2016-01-01

    Although montane sky islands surrounded by desert scrub and shrub steppe comprise a large part of the biological diversity of the Basin and Range Province of southwestern North America, comprehensive ecological and population demographic studies for high-elevation small mammals within these areas are rare. Here, we examine the ecology and population parameters of the Palmer’s chipmunk (Tamias palmeri) in the Spring Mountains of southern Nevada, and present a predictive GIS-based distribution and probability of occurrence model at both home range and geographic spatial scales. Logistic regression analyses and Akaike Information Criterion model selection found variables of forest type, slope, and distance to water sources as predictive of chipmunk occurrence at the geographic scale. At the home range scale, increasing population density, decreasing overstory canopy cover, and decreasing understory canopy cover contributed to increased survival rates.

    The measurement of ongoing ice-mass loss and associated melt water contribution to sea-level change from regions such as West Antarctica is dependent on a combination of remote sensing methods. A key method, the measurement of changes in Earth's gravity via the GRACE satellite mission, requires a potentially large correction to account for the isostatic response of the solid Earth to ice-load changes since the Last Glacial Maximum. In this study, we combine glacial isostatic adjustment modelling with a new GPS dataset of solid Earth deformation for the southern Antarctic Peninsula to test the current understanding of ice history in this region. A sufficiently complete history of past ice-load change is required for glacial isostatic adjustment models to accurately predict the spatial variation of ongoing solid Earth deformation, once the independently-constrained effects of present-day ice mass loss have been accounted for. Comparisons between the GPS data and glacial isostatic adjustment model predictions reveal a substantial misfit. The misfit is localized on the southwestern Weddell Sea, where current ice models under-predict uplift rates by approximately 2 mm yr-1. This under-prediction suggests that either the retreat of the ice sheet grounding line in this region occurred significantly later in the Holocene than currently assumed, or that the region previously hosted more ice than currently assumed. This finding demonstrates the need for further fieldwork to obtain direct constraints on the timing of Holocene grounding line retreat in the southwestern Weddell Sea and that GRACE estimates of ice sheet mass balance will be unreliable in this region until this is resolved.

    Ma, Mingwei; Ren, Liliang; Singh, Vijay P.; Tu, Xinjun; Jiang, Shanhu; Liu, Yi

    2015-02-01

    The lack of a system/model for integration of drought-related information has been an important obstacle in efforts for accurate and reliable drought monitoring and prediction. This study proposes an integrated multivariate standardized drought index (i.e. standardized Palmer drought index-based joint drought index, SPDI-JDI), where the Palmer scheme/model is accepted as a multivariate multi-index conceptual framework that integrates multiple drought-related indicators for characterizing drought. Using the meteorological data of ten climate divisions from Texas, the computed SPDI-JDI index is first compared to various ground observations (e.g. streamflow, lake/reservoir water level, soil moisture content and groundwater level) for the reflection of drought/wetness conditions. Moreover, the SPDI-JDI is also evaluated against Palmer drought indices and US Drought Monitor for drought detection. Results indicate that the SPDI-JDI is in good/acceptable agreements with surface and subsurface water anomalies and performs well with respect to the integrated use of Palmer drought severity index, Palmer modified drought index, Palmer hydrologic drought index and Palmer Z index as well as to the US Drought Monitor observations. Potential implications are that the SPDI-JDI allows for insights into different impacts of drought and leads to high probability of drought detection versus multi-source drought information, implying attractive properties originating from its physically inclusive and multivariate joint probabilistic combined nature.

    Objective The purpose of this article is to explore the postmodern, postrational, and postconventional core of DD Palmer's self-sense and philosophy. Discussion DD Palmer's self and philosophy can be viewed as a reaction to the self of modernity and its challenges of a fracture between mind and body, spirit, and nature. It is argued that Palmer's solution to these vexing problems facing the modern self was to use postrational and postconventional logic to overcome the dualisms. His philosophy resonates with similar postrational approaches, most notably, the German idealist Schelling. Conclusion It is argued that Palmer was one of the first postrational individuals in America and that chiropractic was an attempt at the first postrational health profession. PMID:22693480

    Senzon, Simon A.

    2011-01-01

    Objective The purpose of this article is to trace the foundations of DD Palmer's sense of self and philosophy of chiropractic to its sources in modern Western philosophy as well as current metatheories about modernity. Discussion DD Palmer's sense of self was indicative of a modern self. A modern self is characterized as a self that developed after the Western Enlightenment and must come to terms with the insights of modernity such as Cartesian dualism, Spinoza's substance, Rousseau's expressivism, and Kant's critiques. It is argued that Palmer's philosophy can be viewed as part of the this tradition alongside his involvement in the 19th century American metaphysical religious culture, which was itself a response to these challenges of the modern self of modernity. Conclusion Palmer's development of chiropractic and its philosophy was a reaction to the challenges and promises of modernity. PMID:22693479

    Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are relatively new medications for diabetes that offer a weight-loss profile that can be considered desirable for patients with both type 2 diabetes (T2D) and obesity. GLP-1 RA are effective in combination with insulin, and even slightly superior or at least equal to short-acting insulin in T2D; however, since they work in the incretin system, they may not be effective in long-standing disease. Additionally, only recently have publications reported their cardiovascular safety, and there is limited evidence for long-term effectiveness. The work presented by Huetson et al. offers a much needed perspective through a medical economic model for the long term cost-effectiveness of GLP-1 RA. The authors found benefits in quality-adjusted life years and reduced lifetime healthcare costs. While there are a few limitations, this study contributes to the understanding of these agents and their impact on the epidemics of obesity in T2D, where weight management is no longer an option, but an essential component of the diabetes plan of care.

  11. The effects of mindfulness on executive processes and autobiographical memory specificity.

    PubMed

    Heeren, Alexandre; Van Broeck, Nady; Philippot, Pierre

    2009-05-01

    Previous studies have found that mindfulness training reduces overgeneral memories and increases autobiographical memory specificity (e.g., [Williams, J. M. G., Teasdale, J. D., Segal, Z. V., & Soulsby, J. (2000). Mindfulness-based cognitive therapy reduces overgeneral autobiographical memory in formerly depressed patients. Journal of Abnormal Psychology, 109, 150-155]). However, little work has investigated the mechanisms underlying this effect. The present study explored the role of executive processes as a mediator of MBCT effects in an unselected sample. An autobiographical memory task, a cognitive inhibition task, a motor inhibition task, a cognitive flexibility task and a motor flexibility task were administered before and after intervention. Compared to matched controls, MBCT participants showed increased autobiographical memory specificity, decreased overgenerality, and improved cognitive flexibility capacity and capacity to inhibit cognitive prepotent responses. Mediational analyses indicated that changes in cognitive flexibility partially mediate the impact of MBCT on overgeneral memories. Results are discussed in terms of Conway's [2005. Memory and the self. Journal of Memory and Language, 53, 594-628] autobiographical memory model. PMID:19232573

    We develop a piecewise linear (PWL) Galerkin finite element spatial discretization for the multi-dimensional radiation diffusion equation. It uses recently introduced piecewise linear weight and basis functions in the finite element approximation and it can be applied on arbitrary polygonal (2D) or polyhedral (3D) grids. We first demonstrate some analytical properties of the PWL method and perform a simple mode analysis to compare the PWL method with Palmer's vertex-centered finite-volume method and with a bilinear continuous finite element method. We then show that this new PWL method gives solutions comparable to those from Palmer's. However, since the PWL method produces a symmetric positive-definite coefficient matrix, it should be substantially more computationally efficient than Palmer's method, which produces an asymmetric matrix. We conclude that the Galerkin PWL method is an attractive option for solving diffusion equations on unstructured grids.

  13. Innate intelligence: its origins and problems

    PubMed Central

    Morgan, Lon

    1998-01-01

    Animal Magnetism and Radionics were among several occult practices used during the 19th century for the treatment of disease. D.D. Palmer was exposed to these teachings and derived many of his ideas about health from the folk medicine practices of his time. As a ‘magnetic healer’ Palmer believed he was correcting an undefined fifth force in the body that is otherwise unknown to science. Palmer believed he could influence this fifth force, termed Innate Intelligence, and that it was the explanation for the presence or absence of health. Today, Innate Intelligence remains an untestable enigma that isolates chiropractic and impedes its acceptance as a legitimate health science. The concept of Innate is derived directly from the occult practices of another era. It carries a high penalty in divisiveness and lack of logical coherence. The chiropractic profession must decide whether the concept of Innate should be retained.

  15. Evolution of aerosol and CCN properties on the Antarctic Peninsula and Southern Ocean during the spring and summer seasons.

    The Southern Ocean has been identified as one of the key regions that need aerosol measurements to improve our models of global climate change. The Portable AERosol Observing System (PAEROS) was deployed in an extended field campaign to measure CCN and aerosols in Antarctica and the Southern Ocean from October 2013 to mid-March 2014. PAEROS is a lightweight, man-portable instrument package developed at the Scripps Institution of Oceanography for the purpose of collecting autonomous measurements of aerosol and cloud condensation nuclei (CCN) properties in remote and challenging environments. The initial phase involved the PAEROS package sampling onboard the R/V Gould during the five-day transit of the Drake Passage between Punta Arenas, Chile and Palmer Station on the Antarctic Peninsula. Upon arrival at Palmer Station, PAEROS was transferred to land and installed on top of a hill about 500 m from the main buildings. For five months, aerosol and CCN number concentrations, size distributions, black carbon concentrations, solar fluxes, and meteorological parameters were continuously measured at Palmer Station. The experiment covered most of an austral spring and summer cycle, during which time the sea ice retreated and biological activity flourished along the Antarctic Peninsula. While crossing the Drake Passage, a distinct gradient in aerosol concentrations was observed with increasing distance from South America. At Palmer Station, the total aerosol concentrations showed a seasonal cycle with lowest concentration in air masses originating from the Antarctic continent and highest number concentrations coming from the ocean during the peak of biological activity. Chlorophyll concentrations are routinely measured at Palmer Station and showed peak activity in the month of January 2014. Total aerosol and CCN concentrations increased in late spring (November) as the sea ice recedes from Palmer Station, probably a result of being closer to sea spray and biological activity. Aerosol hygroscopicity decreased for ultrafine particles during the biological periods, which suggests enhanced organic contribution to the composition of smaller particles.

    The perturbation in the signal strength of a VLF transmitter by another transmitter heating the ionosphere on the great circle path to the receiver is calculated for two cases: The NAA-Palmer path heated by the VLF transmitter, NAU, and the Omega Norway-Skibotn path heated by the MF transmitter, heating, near Tromsoe. Comparison implies either that VLF heating is over 100 times more effective than MF heating in terms of the perturbation produced, per RF heating watt, in VLF propagation in the Earth-ionosphere wave-guide or that the observed effect at Palmer is fortuitous or spurious.

    1975-01-01

    The Carrara Formation is a heterogeneous sequence of quartzites, siltstones, shales, limestones, dolostones, and mixed terrigenous-carbonate rocks. It is Early and Middle Cambrian in age (Stewart, 1970; Palmer, 1971). Figure 32-1 illustrates the general distribution of Carrara lithologies along a transect approximately normal to depositional strike (Fig. 32-2). The formation contains three “grand cycles” (Aitken, 1966; Palmer, 1971), which terminate at the top of massive limestone members. A fourth cycle begins with the uppermost shale of section 9 and is not illustrated in sections 3 through 8. This fourth cycle grades into the overlying Bonanza King Formation.

    In western literature, the oldest description of symptoms of PTSD, an anxiety group of disorder, is seen in Homer's Iliad written around 720 BC. According to Shay, Achilles was suffering from symptoms of PTSD. However, in the Indian literature it was mentioned around 5000 BC. The description of a PTSD-like syndrome is seen in the Ramayana, although it was not described as PTSD or by any other similar name. Ravana's brother Marrich was having symptoms of PTSD after he was grievously hurt by Lord Rama's arrow and was almost dead. This traumatic event threatened his physical integrity. He developed all the symptoms of PTSD, like hyper-arousal, re-experiencing the events and avoidance. He also gave up his natural work of harassing the monk and got engaged in meditation and austerities. His symptoms lasted for many years till Lord Rama killed him, while he was masquerading as a golden deer to deceive Sita. In another ancient epic Shrimad Bhagavatam, Maharshi Ved Vyasa described the symptoms of Generalized Anxiety Disorder (GAD). The demon King Kansha developed GAD-like symptoms, when Lord Krishna killed all his demons and threatened to kill him. He developed symptoms of GAD, like excessive worry about the attack from his arch foe Krishna, difficulty in concentration and difficulty in falling asleep. Like Marrich, the symptoms of Kansha also lasted until Lord Krishna killed him. PMID:21180424
