  2. Joseph Conrad's Lord Jim: Reconsiderations

    Directory of Open Access Journals (Sweden)

    Ali Albashir Mohammed Al-Haj

    2014-12-01

    Full Text Available The present study aims at reconsidering critically Joseph Conrad's Lord Jim. Joseph Conrad is a great master of English prose who writes normally of the sea, of the Eastern islands, of the English character as seen against a background of the exotic or faced with difficulties. The power of Conrad's feelings for Jim, as well as the force of his judgment  against him, are the responses  of a man mightily involved on two planes, one personal and one public , with the dynamics of good and evil. The evil in Lord Jim is one thing on the surface and another beneath our grasp. It is of course the evil of men who have no sense of loyalty to anything.

  3. Joseph Conrad's tormented Rescue (fantasy).

    Freedman, William

    2014-02-01

    Joseph Conrad was a notoriously tormented writer for whom the creative act was often a punishment severe enough to drive him into paralyzing depressions that delayed the completion of his novels, sometimes for years. By far the most agonizing of these projects was The Rescue, a novel he began in 1898, abandoned a year later, tried unsuccessfully to continue several times over the next two decades, but was only able to resume in 1918 and to complete, after another tortured two-year struggle, in 1920. An explanation for this incapacity, that is powerfully suggested by the novel's evocative title and perhaps unintentionally ironic subtitle (A Romance of the Shallows) has not yet been explored. Using Freud's 1910 essay on the rescue fantasy, "Contributions to the Psychology of Love: A Special Type of Choice of Object Made by Men," and Emanuel Berman's instructive revision and expansion of the concept in his 2003 American Imago essay, "Ferenczi, Rescue, and Utopia," I argue that a substantial explanation for Conrad's tormented history with The Rescue is ascribable to its quite remarkably faithful treatment of a rescue fantasy with deep and disabling resonance for its author. More specifically, the difficulty was compounded by the novel's dramatization of the soul-crushing conflict between two such fantasies: one in the service of the masculine ideal of unflinching dedication to a heroic purpose, the other promising satisfaction to the equally potent demands of emotional and sexual desire. Features of Conrad's narrative fit so tightly and consistently with the theory as Freud (and Abraham) proposed and as Berman elaborated it that The Rescue offers itself as one of those rare and reinforcing instances wherein the literary text seems to validate the psychoanalytic theory at least as persuasively as the theory "understands" the text.

  4. A Reading of Joseph Conrad's The Tale

    OpenAIRE

    Zadeh, Mohammad Reza Modarres

    2013-01-01

    The Tale is a short story by Joseph Conrad. Typical of a Conrad story it is set at sea. The sea is symbolic of the unconscious and this story may be read as a story of the unconscious. On the outside, it seems simple; a man tells a woman a tale of the commanding officer of a patrol ship who gives false directions to another ship and sends it to its doom. In between the lines of the seemingly simple plot, however, can be read another tale; one which speaks of a human sea deeper than the sea of...

  5. Waiting for the Barbarians: Conrad, Kafka, Coetzee

    Full Text Available The threat of the “Barbarians at the gates”, who bring chaos and death upon civilization, has gradually become one of the thematic obsessions of contemporary imagination. Along the course of the 20th century, the Enemy became less and less the bearer of another culture, and more and more the carrier of a Nonculture or an Anticulture. Such evolution is particularly evident in popular imagination, in all the comics and blockbuster films which stage the final battle between the heros of (white, Western civilization against a dreadful army of barbarian enemies. The article focus on three works – Heart of Darkness by Joseph Conrad, Beim Bau der chinesischen Mauer by Franz Kafka, Waiting for the Barbarians by J.M. Coetzee – which investigate on this mechanism from within, highlighting its ideological implications and its tragic potential.

  6. READING COLONIZATION IN CONRAD'S TRANS-RACIAL LOVE PLOTS

    2017-07-01

    Full Text Available The study is about a close look at Conrad's trans-racial romance related to the Victorian period. Trans-racial love between white men and non-white women becomes a popular theme in the early works of Josep Conrad, a famous writer of the late Victorian period. Using a closely technical reading in the three of Conrad's works Lord Jim, Almayer's Folly, and An Outcast of the Island, we can show that such a trans-racial romance is not merely meant for appreciating equivalence. In turn, the trans-racial romance of Conrad's can be understood as the reflection of the Western colonization on the East where the white men take a role as subjects who had dominately explored while the non-white women as objects who are passively being explored. Key words: colonization, race, romance plot, subject, object, and dominance

  9. Conrad's view of revolution/anarchism in under western eyes Conrad's view of revolution/anarchism in under western eyes

    Directory of Open Access Journals (Sweden)

    Antonio Eduardo de Oliveira

    2008-04-01

    Full Text Available It is my main purpose to discuss in this paper three relevant topics concerned with Joseph Conrad's novel Under Western Eyes, namely: the author's view of revolution and anarchism and its relation with his Polish experience; how critical Conrad is of both autocracy and revolution and finally to discuss where in, the novel the writer is sympathetic to revolution. To begin with, let me mention some aspects of Conrad's Polish background. First of all, he was a Pole, born in the Russian-occupied Poland of 1857 as the son of one of the most spirited participants in the Polish National Comittee, and with a profound fear of Russian autocratic power in his blood. Politics, nationalism, the forces of imperialism and rebellion, were the first and deepest parts of his inheritance. Conrad's character was linked to the patriotic and nationalistic ardour of his father's nature, an idealist revolutionary, and to the conservatism of his uncle Tadeuz Bobrowski his guardian during youth. The duality of thought conditioned by Apollo Korzeniowski, the father, and Tadeuz Bobrowski made his character divided all his life long. The political approach in Under Western Eyes exemplifies the writer's duality of thought. In order to write this novel Conrad found uggestions in the writings of Russian novelists, mainly Dostoievsky's Crime and Punishment. Although the book fully justifies this assertion, the writer denies it and even affirmed in a letter to a friend that he had a "Russophobia", and that he did not like the works of the famous Russian writer. It is my main purpose to discuss in this paper three relevant topics concerned with Joseph Conrad's novel Under Western Eyes, namely: the author's view of revolution and anarchism and its relation with his Polish experience; how critical Conrad is of both autocracy and revolution and finally to discuss where in, the novel the writer is sympathetic to revolution.

  11. AN AMBIVALENT CONRAD IN AN OUTPOST OF PROGRESS

    Directory of Open Access Journals (Sweden)

    Majid SADEGHZADEGAN

    2017-06-01

    Full Text Available The present paper aims to portray the racist and anti-racist dimensions of Joseph Conrad in his short story “An Outpost of Progress” (1897. Conrad’s alleged racist status espoused by thinkers such as Chinua Achebe and Edward Said, particularly in Heart of Darkness, has constantly been the subject of heated debates in literature. A myriad of analogous traces in the short story “An Outpost of Progress” lend Conrad’s voice to a highly racist position while many other anti-racist traces observed in the story could lower the resonance of the same voice, hence an inconclusive ambivalence or a liminal position in Conrad’s tone. This paper is thus divided into two sections. The first section has the racist traces of Conrad in the short story on top of its agenda whereas the second section ventures into the anti-racist footprints of Conrad’s voice in the story. In so doing, this paper sets out to turn to Achebe and Said in arguing for the racist position of Conrad; however, the anti-racist facets of the story will be substantiated via relying on the arguments developed by thinkers such as D. C. R. A. Goonetilleke and Benita Parry. An ironic ambivalence swaying from a racist tone to an anti-racist tone in Conrad’s voice in “An Outpost of Progress” is the conclusive maxim.

    The work of the Task Group 5.2 'Research Studies on Biokinetic Models' of the CONRAD project is presented. New biokinetic models have been implemented by several European institutions. Quality assurance procedures included intercomparison of the results as well as quality assurance of model formulation. Additionally, the use of the models was examined leading to proposals of tuning parameters. Stable isotope studies were evaluated with respect to their implications to the new models, and new biokinetic models were proposed on the basis of their results. Furthermore, the development of a biokinetic model describing the effects of decorporation of actinides by diethylenetriaminepentaacetic acid treatment was initiated. (authors)

    2008-01-01

    The development of a software tool (CONRAD) was initiated at CEA/Cadarache to give answers to various problems arising in the data analysis of nuclear reactions. This tool is then characterized by the handling of uncertainties from experimental values to covariance matrices for multi-group cross sections. An object oriented design was chosen allowing an easy interface with graphical tool for input/output data and being a natural framework for innovative nuclear models (Fission). The major achieved developments are a data model for describing channels, nuclear reactions, nuclear models and processes with interface to classical data formats, theoretical calculations for the resolved resonance range (Reich-Moore) and unresolved resonance range (Hauser-Feshbach, Gilbert-Cameron,...) with nuclear model parameters adjustment on experimental data sets and a Monte Carlo method based on conditional probabilities developed to calculate properly covariance matrices. The on-going developments deal with the experimental data description (covariance matrices) and the graphical user interface. (authors)

    Water is an essential and increasingly scarce resource that should be preserved. The evolution of the human population and communities has contributed to the global decrease of potable water availability and the reduction of its consumption is now compulsory. Rainwater harvesting systems (RWHS) are emerging as a viable alternative source for water consumption in non-potable uses. The present study aims to contribute to the promotion of water efficiency, focusing on the application of rainwater harvesting systems in commercial buildings, and comprises four stages: (i) development of a technical evaluation tool to aid the design of RWHS and support their financial evaluation; (ii) validation of the tool using operational data from an existing RWHS installed at Colombo Shopping Center, in Lisbon, Portugal; (iii) assessment of the sensibility of the technical evaluation tool results to the variation of the inputs, namely the precipitation and consumption, through a parametric analysis for the Colombo Shopping Center; and (iv) comparison of the performance and financial feasibility of hypothetical RWHS in two existing commercial buildings. The technical tool was applied to two Sonae Sierra's shopping centers, one in Portugal and one in Brazil. The installation of a 200-m 3 tank is advised for the first case study, allowing non-potable water savings of 60% but a payback period of about 19 years. In the Brazilian shopping, the implementation of a tank with a capacity ranging from 100 to 400 m 3 leads to non-potable savings between 20 and 50%, but with smaller payback period, under 2 years, due to the relatively lower investment costs and higher water fees.

In the first section of this paper several definitions of translation and rewriting (mainly by Eco, Bassnet and Lefevere, and Torop are reviewed, thus highlighting contrasting positions concerning the very definition thereof. The main characteristics of an Italian version of The Secret Sharer for young readers – L’ospite segreto translated by Pieroni and Liberio – are listed, showing the editing and translating strategies underlying this specific text in which the target reader is very different from the source reader. The role of the target reader in translation practice is eventually examined, by stressing the vital status of metalanguage in translation criticism.

    The Conrad Observatory (COBS) housed the national geophysical observatory of Austria and is located 50 km south west of Vienna within the carbonate sequence of the "Wettersteinkalk". Parameters monitored at the facility comprise environmental data, seismic signals, gravity, geomagnetic components and also natural gamma rays. A subsurface tunnel, 150 meters long and oriented E-W is driven into the calcareous sequence at a depth of 50 meters. The tunnel is lined with a concrete carapace, ~20 cm thick. The tunnel observatory is separated from the external atmosphere by 3 tight doors, resulting in a stable temperature of 6.85±0.04°C. A gamma detector (3×3", NaI, SCA) is used measure the variation of the gamma radiation from radon in the air of the tunnel, at a resolution of 1 minute, which is accumulated to form a 15-minute count rate. The sensor is placed on a concrete block at 135 meters. Several SSNTD measurements in the tunnel indicated radon level in the level of 1.5 kBq/m^3. The background gamma radiation, due probably mainly to sources in the concrete is in the order to 2×105 counts (per 15-minutes). A long term variation of radon is reflected as an annual radon signal with large amplitude (2×105 counts) and a maximum in summer. Small to large (2×105 counts) non periodic multi-day signals lasting from two to several tens of days are superimposed. Daily periodic signals of much lower amplitude are observed, with amplitudes generally up to 4×104 counts. The amplitude of the non-periodic multi-day is coupled to amplitude of the annual signal, and the amplitude of the periodic daily signal is modulated by the multi-day variation. The source of the radon in the air of the tunnel is from the concrete lining the floor and walls of the tunnel. The variation patterns and their systematic characteristics cannot be ascribed to local variations of pressure and temperature (stable). These limitations indicate that other driver(s), external to the tunnel, are forcing

  4. On the Dark Side: Conrad's "The Secret Sharer" and Valenzuela's "La palabra asesino"

    Directory of Open Access Journals (Sweden)

    Donald L. Shaw

    2008-01-01

    Full Text Available Conrad’s famous “The Secret Sharer” and the short story “La palabra asesino” [“The Word ‘Killer’” in its English translation] by the Argentine Luisa Valenzuela both concern psychological self-exploration and self-discovery, through contact with a killer, a situation which challenges conventional moral standards. It is suggested that a comparison between the two stories may throw reciprocal light on both of them. In each story an act or acts of murder becomes a trigger which sets off a train of psychological events, somewhat different in the two cases. Discussion of the differences highlights the authors' priorities and the significance they attach to the darker side of the human personality. Both stories are highly ambiguous; but the ambiguity serves a different purpose in each case. Conrad is concerned with psychological "doubling"; Valenzuela with exploration of aspects of the human personality which in turn may be related to aspects of Argentina's collective personality as it expressed itself during the “Dirty War.” An examination of the different forces in play in the two stories improves our understanding of both.

    Full text: This presentation gives an overview on the research activities that EURADOS coordinates in the field of radiation protection dosimetry in medicine. EURADOS is an organization founded in 1981 to advance the scientific understanding and the technical development of the dosimetry of ionising radiation in the fields of radiation protection, radiobiology, radiation therapy and medical diagnosis by promoting collaboration between European laboratories. EURADOS operates by setting up Working Groups dealing with particular topics. Currently funded through the CONRAD project of the 6th EU Framework Programme, EURADOS has working groups on Computational Dosimetry, Internal Dosimetry, Complex mixed radiation fields at workplaces, and Radiation protection dosimetry of medical staff. The latter working group coordinates and promotes European research for the assessment of occupational exposures to staff in therapeutic and diagnostic radiology workplaces. Research is coordinated by sub-groups covering three specific areas: 1: Extremity dosimetry in nuclear medicine and interventional radiology: this sub-group coordinates investigations in the specific fields of the hospitals and studies of doses to different parts of the hands, arms, legs and feet; 2: Practice of double dosimetry: this sub-group reviews and evaluates the different methods and algorithms for the use of dosemeters placed above and below lead aprons, especially to determine personal doses to cardiologists during cardiac catheterisation, but also in CT-fluoroscopy and some nuclear medicine developments (e.g. use of Re-188); and 3: Use of electronic personal dosemeters in interventional radiology: this sub-group coordinates investigations in laboratories and hospitals, and intercomparisons with passive dosemeters with the aim to enable the formulation of standards.

    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." Participants included 49 third-year medical students. Their book reports were analyzed. 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. 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.

    In the framework of the European InterregIV Italy/Austria project: "HAREIA - Historical and Recent Earthquakes in Italy and Austria" the Central Institute for Meteorology and Geodynamics (ZAMG) and Mathematic and Geosciences Department of University of Trieste (DMG) are upgrading the transfrontier seismic network of South-Eastern Alps with new 12 accelerometric stations to enhance the strong motion instrument density near the Austria/Italy border. Various public institutions of the provinces Alto Adige (Bolzano Province), Veneto (ARPAV) and Friuli Venezia Giulia (Regional Civil Defense) in Italy and in the Austrian province of Tyrol are involved in the project. The site selection was carried out to improve the present local network geometry thus meeting the needs of public Institutions in the involved regions. In Tyrol and Alto Adige some strategic buildings (hospitals and public buildings) have been selected, whereas in Veneto and Friuli Venezia Giulia the sites are in the free field, mainly located near villages. The instruments will be installed in an innovative box, designed by ZAMG, that provides electric and water isolation. The common choice regarding the instrument selection has been the new Kinemetrics Basalt ® accelerograph to guarantee homogeneity with the already installed instrumentation and compatibility with the software already in use at the different seismic institutions in the area. Prior to deployment the equipment was tested at the Conrad Observatory and a common set-up has been devised. The Conrad Observatory, seismically particularly quiet, permits to analyze both the sensor and the acquisition system noise. The instruments were connected to the network and the data sent in real-time to the ZAMG data center in Vienna and the DMG data center in Trieste. The data have been collected in the database and analyzed using signal processing modules PQLX and Matlab. The data analysis of the recordings at the ultra-quiet Conrad Observatory pointed out

  8. The epigenetic landscape in the course of time: Conrad Hal Waddington's methodological impact on the life sciences.

    Baedke, Jan

    2013-12-01

    It seems that the reception of Conrad Hal Waddington's work never really gathered speed in mainstream biology. This paper, offering a transdisciplinary survey of approaches using his epigenetic landscape images, argues that (i) Waddington's legacy is much broader than is usually recognized--it is widespread across the life sciences (e.g. stem cell biology, developmental psychology and cultural anthropology). In addition, I will show that (ii) there exist as yet unrecognized heuristic roles, especially in model building and theory formation, which Waddington's images play within his work. These different methodological facets envisioned by Waddington are used as a natural framework to analyze and classify the manners of usage of epigenetic landscape images in post-Waddingtonian 'landscape approaches'. This evaluation of Waddington's pictorial legacy reveals that there are highly diverse lines of traditions in the life sciences, which are deeply rooted in Waddington's methodological work.

    A post-rehabilitation audit of the derelict Conrad base metal mine, eastern Australia, indicates ongoing environmental hazard regarding acid mine drainage and concentrations of arsenic and lead to 3 wt% in the soil and sediment. In order to rehabilitate remote contaminated sites effectively, on-site analyses should be carried out to ensure that the materials used to rehabilitate the site are not contaminant-bearing. Understanding the geomorphic setting of the rehabilitated areas is also important in understanding where, and for what period, contaminated materials might be stored in fluvial systems downstream of mine workings. Chemical and geomorphic audits should form a fundamental part of all rehabilitation works to ensure favourable environmental outcomes. - Post-rehabilitation audit of mine reveals ongoing As and Pb environmental hazard enhanced by acid drainage and site geomorphology

    The European razor shell Ensis minor (Chenu 1843) and the American E. directus (Conrad 1843) have a diploid chromosome number of 38 and remarkable differences in their karyotypes: E. minor has four metacentric, one metacentric-submetacentric, five submetacentric, one subtelocentric and eight telocentric chromosome pairs, whereas E. directus has three metacentric, two metacentric-submetacentric, six submetacentric, six subtelocentric and two telocentric pairs. Fluorescent in situ hybridisation (FISH) using a major ribosomal DNA probe located the major ribosomal genes on one submetacentric chromosome pair in both species; FISH with a 5S ribosomal DNA (5S rDNA) probe rendered one chromosomal (weak) signal for E. minor and no signal for E. directus, supporting a more dispersed organisation of 5S rDNA compared to the major ribosomal genes. The vertebrate telomeric sequence (TTAGGG) n was located on both ends of each chromosome, and no interstitial signals were detected. In this work, a comparative karyological analysis was also performed between the four Ensis species analysed revealing that the three European species studied so far, namely E. minor, E. siliqua (Linné 1758) and E. magnus Schumacher 1817 show more similarities among them than compared to the American species E. directus. In addition, clear karyotype differences were found between the morphologically similar species E. minor and E. siliqua.

  14. Radiation protection of medical staff: a coordinated action by EURADOS on extremely dosimetry and the use of active personnel dosemeters (CONRAD)

    Monitoring of workers constitutes an integral part of any radiological protection program. However, unresolved issues in radiation protection of medical staff still remain. Research and establishment of guidelines are necessary on a variety of issues such as extremity dosimetry (fingers, eye lenses, etc), the use of double dosimetry above and below lead aprons, or the use of electronic personal dosimeters in interventional procedures. Medical practices are also evolving fast, and new techniques with ionising radiation emerge very regularly, thus implying the need of radiation protection measures for medical staff, and the implementation of new monitoring programs. In some medical applications of radiation there is an increased risk of high local exposures because of direct handling of sources or the use of beta-emitters. However, despite the large number of workers that are exposed in the medical field worldwide, only few measurements of extremity doses have been reported in the literature. Some activities of EURADOS Working Group 9 (WG9) were sponsored by the European Commission in the CONRAD project. This CONRAD project was aiming at the coordination of research on radiation protection at the workplace. Working group 9 has been involved in the coordination and promotion of European research in the field of Radiation Protection Dosimetry for Medical Staff. One of the objectives of this working group was to formulate the state of the art and to identify areas in which improvements were needed. For some of these medical applications the skin of the fingers is the limiting organ from the point of view of individual monitoring of external radiation. The wide variety of radiation field characteristics in a medical environment, and the difficulty of measuring a local dose that is representative for the maximum skin dose (usually with one single detector), makes it difficult to perform extremity dosimetry with an accuracy similar to whole-body dosimetry. Therefore a

    The Finnish Geodetic Institute (FGI) the progenitor of Finnish Geospatial Research Institute of NLS designed and built a 5.5m long prototype of interferometric water level tiltmeter (iWT) in early 2014. Geodetic and Geophysical Institute (GGI), Sopron, Hungary bought the instrument and started tilt measurement in August 2014 at the Conrad observatory (COBS), Austria to monitor geodynamical phenomena like microseisms, free oscillations of the Earth, earth tides, mass loading effects and crustal deformations in cooperation with Austrian Central Institute for Meteorology and Geodynamics (ZAMG) and the FGI. On the July 16 2015 a Lippmann-type 2D tilt sensor (LTS) was also installed by GGI on the 6 m long pier where iWT was set up previously. This situation opens a possibility to do broad band (from secular to seismic variations up to 15 Hz) geophysical signal analysis comparing the responses of long (several meters) and short (a few decimeters) base instruments implementing different physical principles (relative height change of a level surface and inclination change of the plumb line). The characteristics of the sensors are studied by the evaluation of the spectra of recorded signals dominated by microseisms. The iWT has internal interferometric calibration and it can be compared to Lippmanns tilt meter one. Both instruments show good long term ( > 1 day) stability when earth tides and ocean and air mass loading tilts are modelled.

    2011-12-01

    Classical Greek and Roman writers documented the diagnosis and treatment of psychiatric illness in ancient times. Following the fall of the Western Roman Empire however, we find little writing on the topic in early Medieval Europe. Yet in Britain, medical texts survived and were complemented by local traditions and treatments. This article explores the best-known Anglo-Saxon medical texts, the Leechbooks and Lacnunga, for evidence of psychiatric illness and the treatments employed by physicians in the tenth century. The difficulties encountered when working with sources translated from Old English and speculations about the supernatural aetiology ascribed to these illnesses are detailed. The efficacy of the leechdoms (treatments) described are also investigated for both their placebo and potential pharmacological effects.

    Full Text Available Marine organisms are affected by organotin compounds due to the cumulative, deleterious effects of these latter. The most evident and well known consequence of organotin contamination is imposex, a hormonal disruption that causes a superimposition of sexual male features in females of prosobranchia neogastropod molluscs such as Stramonita haemastoma floridana. Molluscs accumulate organotins mainly because of their poor ability to eliminate TBT and DBT from their tissues. The aim of this study was to analyze organotin uptake by ingestion experimentally, using uncontaminated subjects (S. haemastoma floridana fed with organotin-contaminated oysters (Crassostrea rhizophorae. A total of 248 gastropods, distributed in 7 tanks with uncontaminated water and contaminated food, were used in this study, a control group being fed uncontaminated oysters. Every 15 days, the individuals of one of the tanks were examined for the presence of imposex. Development of imposex was measured using the VDSI, RPSI and RPLI indexes. The animals had already developed imposex within the first 15 days, all the indexes measured (RPLI, RPSI and VDSI having increased significantly with duration of exposure, indicating that the animals were probablycontaminated by the food and had accumulated the pollutant. New paths of imposex development were also observed.Organismos marinhos são afetados por compostos organoestânicos que causam uma série de efeitos deletérios aos mesmos. O mais conhecido efeito da contaminação por organoestânicos é o imposex. Esse fenômeno consiste na masculinização de fêmeas de moluscos neogastrópodes tais como Stramonita haemastoma floridana. Esses compostos tendem a se acumular em moluscos devido a sua baixa capacidade de eliminá-los. Um total de 248 indivíduos de S. haemastoma floridana foram coletados de uma população livre qualquer indício de imposex. Esses animais foram mantidos em 7 aquários, com aproximadamente 30 indivíduos cada, 1 desses aquários foi considerado como controle e os animas do mesmo alimentados com ostras obtidas de locais onde não se verificou a ocorrência de imposex em neogastrópodes nativos. Os animais nos outros 6 aquários foram alimentados com ostras obtidas em local onde a incidência de imposex entre os gastrópodes nativos revelou-se muito alta. A cada 15 dias, por um período total de 90 dias, os animais de um dos tanques eram retirados e analisados quanto à presença de imposex. Os níveis de imposex foram quantificados através da % de imposex e dos índices: RPLI, RPSI e VDSI. Observou-se a indução de imposex em S. haemastoma floridana através da dieta a partir de Crassostrea rhizophora e um aumento significativo dos índices com o decorrer do tempo de exposição. Os animais do aquário controle foram analisados ao fim do experimento não revelando qualquer indício de imposex.

    Complement, activated during infection and injury, has been implicated as a mediator of microvascular injury and obstruction. This study examines how two potent activators of complement, zymosan, and cobra venom factor (CVF), affect systemic and visceral perfusion. Rats were injected with either saline (1 ml/kg), zymosan (5 mg/kg) or CVF (5 units/kg) at t = 0 and 30 minutes. Thermodilution cardiac output, mean arterial pressure, heart rate, systemic vascular resistance, and hematocrit were determined at t = 2 hours. Effective hepatic and renal blood flows, by clearance of galactose and p-aminohippurate respectively, were determined over the next hour. The per cent change in total hemolytic complement from t = 0 to t = 3 hours was determined by immune hemolysis of sheep erythrocytes. There was no difference in systemic hemodynamic parameters between the three groups. Hepatic blood flow was depressed in both the zymosan (3.83 +/- 0.23 ml/min/100 g) and CVF (3.72 +/- 0.20 ml/min/100 g) groups compared with controls (4.62 +/- 0.19 ml/min/100 g, P less than 0.05). Renal blood flow in the zymosan-treated group (6.40 +/- 0.24 ml/min/100 g) increased over control (4.80 +/- 0.40 ml/min/100 g, P less than 0.05) but was unchanged in the CVF group (5.06 +/- 0.23 ml/min/100 g). The amount of complement activated correlated with the change in hepatic (r = -0.419, P less than 0.05) but not renal (r = -0.008, P = 0.917) flow. Complement activation may occupy a proximal position in the pathogenesis of hepatic ischemia associated with trauma and sepsis.

    1976-01-01

    The mutation breeding programme with a view to rectify the defects of severe susceptibility to important diseases of a few varieties of rice and bread wheat was undertaken using different mutagenic treatments with radiation (X-rays and gamma rays), chemical mutagens (EMS, NMU, NEU) and combination of radiation and chemical mutagens (gamma rays + EMS). In rice two mutant strains have shown moderate resistance to helminthosporiose, one strain to both helminthosporiose and blast and five strains resistant to bacterial leaf blight under artificial epiphytotic conditions. In bread wheat, out of large M 2 population, derived from different mutagenic treatments, the frequencies of appearance of mutants resistant to rust diseases were observed to be 0.03 percent in H.D. 1944 from 0.2 percent EMS treatment, 0.06 percent in H.D. 1999 from 0.01 percent NEU treatment and 0.07 percent in Kalyan Sona from combined treatment with 20 krad gamma rays and 0.4 percent EMS. The mutants bred true for resistance upto M 6 generations. A few of the mutants, resistant to different diseases in rjce and bread wheat, proved to be very promising in yield. An early (earlier to Kalyan Sona by 25 days) mutant, derived from Kalyan Sona, topped in yield out of 49 varieties tested in 1974l75 in Delhi and Pusa. The Kalyan Sona early tested in 1974-75 in Delhi and Pusa. The Kalyan Sona early mutant is having resistance to yellow and brown rusts. (author)

    Full Text Available Local wisdom explains the phenomenon of Watugunung Complex, Sangkuriang Complex, Jaka Sona Complex, and Kamandaka Complex. This phenomenon can be compared to the Oedipus complex phenomena in classical Greek civilization. The similarity phenomenon of Jaka Sona Complex and Oedipus complex is in killing the father. However, Jaka Sona did not marry his mother, even he did not have the desire to his mother while Sangkuriang also killed his father but he failed to marry his mother. Both Watugunung and Oedipus married their mother though Watugunung did not kill his father. Among the five phenomena, only Kamandaka complex is different because he did not kill his father and he did not marry his mother either.  He just wanted to marry a woman who looked like his mother’s face. The local wisdoms happened when healing the disease epidemic by using the three-color oil. Keywords: local wisdom, Oedipus Complex, classical Greek civilization, father’s killing, Tigawarna. Kearifan lokal menjelaskan adanya fenomena Watugunung Complex, Sangkuriang Complex, Jaka Sona Complex, dan Kamandaka Complex. Fenomena tersebut dapat dibandingkan dengan fenomena Oedipus Complex dalam peradaban Yunani klasik. Kesamaan fenomena Jaka Sona Complex dengan Oedipus Complex adalah pembunuhan ayah. Namun, Jaka Sona tidak menyunting ibunya, bahkan ia tidak memiliki hasrat. Sangkuriang juga membunuh ayahnya, tetapi gagal mengawini ibunya. Oedipus dan Watugunung sama-sama mengawini ibunya, tetapi Watugunung tidak membunuh ayahnya. Di antara kelima fenomena tersebut, hanya Kamandaka yang paling ringan karena ia tidak membunuh ayahnya dan tidak mengawini ibunya, melainkan ia mempunyai hasrat terhadap wanita yang mirip dengan wajah ibunya. Muncul kearifan dalam bentuk penyembuhan terhadap wabah penyakit dengan minyak tigawarna. Kata kunci: kearifan lokal, Oedipus Complex, peradaban Yunani klasik, pembunuhan ayah, dan Tigawarna.

    Full Text Available Objective – To explore how collection development policies currently support the role and purpose of prison libraries, and to explore if the accessibility of circulation records impacts on patron privacy.Design – Online survey questionnaire and a case study analysis of the existing policy statements of selected correctional institutions.Setting – The prison library sector in the United States.Subjects – 17 librarians and library staff across ten states in the United States.Methods – An eight-question online questionnaire was used to explore the existing collection development and circulation policies in prison libraries, and the level of adherence to the guidelines of the Association of Specialized and Cooperative Library Agencies (ASCLA and the American Correctional Association (ACA. In addition, participants were encouraged to forward any circulation or collection development policy statements for more detailed analysis. Each policy was then reviewed to assess the degree of alignment or otherwise with the American Library Association’s (ALA Prisoners’ Right to Read guidelines (2010.Main Results – The results of the survey found that 24% of libraries had no formal collection development policy, and at least 53% of libraries had no circulation policy statement. In these instances, the libraries were typically subject to the local policies and procedures of the correctional institution. The purpose of the library and its collection was primarily viewed as: providing recreational reading material; maintaining contact with the outside world and enabling re-entry into the community; and supporting vocational skills and lifelong learning. In selecting materials, the results indicated that a broadly similar approach to that of public libraries was adopted by most institutions, with the exception of any material that may pose a safety or security threat to the institution. In one institution the use of library services or resources for legal purposes or to provide legal assistance was also clearly prohibited in the collection development policy, although approximately half of the libraries did state that providing legal material was one of their roles. The lengthy and arduous approval process for ordering books and other materials (up to ten months in one instance was reported by several participants due to the layers of bureaucracy and controls inherent in the prison setting. With regard to circulation records and confidentiality issues, 35% of libraries deleted such records instantly upon return of the items, compared with 30% that archived them. A further 29% only retained information from the current and most recent patrons for the purposes of assessing and charging for damaged items.Conclusion – The author found the prison library sector to be a relatively challenging environment. In this context, following the existing guidelines and best practice as recommended by the ALA and others, and establishing clear and ethical policy statements can help libraries to support the needs and rights of patrons more effectively.

  6. Using Ethnic Art to Emphasize Laws of Reflection

    The Kolam (Rangolee) art (Fig. 1) from Southern India and Sona drawings (Fig. 2) from Africa show the similarity of lines going around the dots. Kolam is usually drawn, with paste made up of rice powder, on the floor in front of a house. Typically girls draw these in India on occasions such as welcoming the spring season, weddings, or birthdays. Sona drawings are drawn in the sand using fingers. Typically young boys in Africa were taught to draw these as they went through puberty. They used to impress their masters by drawing these designs quickly in sand and erasing them afterwards. So Europeans never learned these designs. Due to slavery this art or knowledge has disappeared.

    This study records length-weight relationships (LWRs) for eleven commercially important marine catfish species of the family Ariidae (sea catfishes) and Plotosidae (eel catfishes) from the northern Arabian Sea coast of Pakistan. The specimens were sampled from December 2014 to November 2015, using bottom trawls with various mesh sizes by commercial vessels. The species were Nemapteryx caelatus, Sciades sona, Arius gagora, Batrachocephalus mino, Netuma thalassina, N. bilineata, Osteogeneiosus militaris, Plicofollis dussumieri, P. tenuispinis, Plotosus limbatus, and P. lineatus. Of the eleven species, two species A. gagora and N. bilineata were recorded for the first time and LWRs for four species A. gagora, N. bilineata, S. sona, and B. mino still have no data in the FishBase database. In addition, new maximum length for each of the three species N. bilineata, O. militaris and B. mino was also found.

    2016-09-01

    This paper is intended to celebrate the 120th anniversary of the discovery of X-rays. X-rays (Roentgen-rays) were discovered on the 8th ofNovember, 1895 by the German physicist Wilhelm Conrad Roentgen. Fifty days after the discovery of X-ray, on December 28, 1895. Wilhelm Conrad Roentgen published a paper about the discovery of X-rays - "On a new kind of rays" (Wilhelm Conrad Roentgen: Ober eine neue Art von Strahlen. In: Sitzungsberichte der Wurzburger Physik.-Medic.- Gesellschaft. 1895.). Therefore, the date of 28th ofDecember, 1895 was taken as the date of X-rays discovery. This paper describes the work of Wilhelm Conrad Roentgen, Nikola Tesla, Mihajlo Pupin and Maria Sklodowska-Curie about the nature of X-rays . The fantastic four - Wilhelm Conrad Roentgen, NikolaTesla, Mihajlo ldvorski Pupin and Maria Sklodowska-Curie set the foundation of radiology with their discovery and study of X-rays. Five years after the discovery of X-rays, in 1900, Dr Avram Vinaver had the first X-ray machine installed in abac, in Serbia at the time when many developed countries did not have an X-ray machine and thus set the foundation of radiology in Serbia.

    A pot experiment was conducted using labelled superphosphate to study the utilization of applied fertilizer phosphorus by three rice varieties, viz., Jaya, Ratna and Sona at tillering, flowering and harvesting stages. Total phosphorus uptake and phosphorus derived from fertilizer increased significantly with increasing level of phosphorus, but per cent utilization of applied phosphorus showed a reverse trend in all the three varieties at all the growth stages. Dry matter yield in general, increased significantly with increasing P levels in all the three varieties. Average soil-p uptake decreased with increasing levels of phosphorus at all the stages.

  3. Distopie voor oë: Eben Venter se duister kuns

    Directory of Open Access Journals (Sweden)

    Harry Sewlall

    2016-08-01

    Full Text Available Sedert die verskyning van Joseph Conrad se novelle, Heart of Darkness, uitgegee as vervolgverhaal in 1899, was daar al verskeie pogings om Conrad se teks te ‘herskryf’, al was die verwantskap met die meesterteks dikwels gering of selfs twyfelagtig. Nog ’n herskrywing van Conrad se teks is Eben Venter se roman Trencherman, aanvanklik in Afrikaans uitgegee as Horrelpoot. Hierdie teks volg die meesterteks baie nougeset na, nie slegs deur aanhalings daaruit as motto’s vooraan elke hoofstuk te gebruik nie, maar ook deur beelde en woorde uit die oorspronklike teks op ooglopende of bedekte wyse in die narratief in te weef. Die vrae waarmee ’n leser soos ek, wat nie vertroud is met Afrikaans nie, gekonfronteer word, is of dit ’n geval van plagiaat is of ’n oefening in intertekstualiteit en ofdie boek eerder ’n poging is om sensasie te wek ten einde meer boeke te verkoop. Hierdie vraevorm die basis vir ’n intertekstuele verkenning van die twee tekste, wat neerkom op ’n stiplees van Conrad se teks langs Trencherman ten einde die intertekstuele skakels tussen die twee tekste te identifiseer. Teoreties is die artikel gebaseer op die werk van Kristeva en Barthes. Die ondersoek het bevestig dat Trencherman inderdaad ’n oefening in intertekstualiteit is, nie slegs as intertekstualiteit nie, maar eerder as ’n in-gesprek-tree met Conrad se meesterteks. Daaruit volg die slotsom dat Trencherman ’n geldige intertekstuele antwoord is op Heart of darkness wat Conrad se beroemde novelle dekonstrueer en die draaiboek daarvan transponeer na ’n distopiese, post-demokratiese Suid-Afrika.

    Full Text Available The study focussed on the Romanian spotted breed-Simmental type was aimed to evaluating the productive potential and some reproductive indices in the period 2013-2015 in Sona farm from Brasov county. The main indicators taken into consideration to analyze the whole herd were the following: milk yield, milk quality, age of first calving, mammary repose and calving interval. Analyzing milk production, this was increasing from 5439 kg in 2013 to 7400 kg in 2015, with an average for the entire period of 6324.33 kg with 4.23% fat and 3.42% protein. Also the fat and protein content have increased over this period, from 4.13 % for fat and 3.25 % for protein in 2013, to 4.34 % and 3.56 respectively in 2015. Analyzing the main indicators of reproduction for a period of three years it was found that calving interval is on average of 401 days and mammary repose is around of 54 days. It is clearly observed that during this period the production is increasing, this shows that cows from the Sona farm records genetic progress regarding qualitative and quantitative milk production. The research has done much to show the productive potential and popularity of the Romanian spotted breed-Simmental type in Transylvania region.

    Full Text Available The sense of agency (SoA is defined as “the registration that I am the initiator of my actions.” Both “direct” and “indirect” measurement of SoA has focused on specific contextualized perceptual events, however it has also been demonstrated that “higher level” cognitions seemingly affect the SoA. We designed a measure of person's general, context-free beliefs about having core agency—the Sense of Agency Scale (SoAS. An exploratory (EFA and confirmatory (CFA factor analyses on samples of 236 (Study 1 and 408 (Study 2 participants yielded two correlated factors we labeled Sense of Positive Agency (SoPA and Sense of Negative Agency (SoNA. The construct validity of SoAS is demonstrated by its low-to-moderate correlations with conceptually relevant tools and by the moderate-strong relationship between the SoNA subscale and obsessive-compulsive (OC symptoms (r = 0.35. We conclude that the SoAS seems to isolate people's general beliefs in their agency from their perceived success in obtaining outcomes.

  16. Dissection of two soybean QTL conferring partial resistance to Phytophthora sojae through sequence and gene expression analysis

    Directory of Open Access Journals (Sweden)

    Wang Hehe

    2012-08-01

    Full Text Available Abstract Background Phytophthora sojae is the primary pathogen of soybeans that are grown on poorly drained soils. Race-specific resistance to P. sojae in soybean is gene-for-gene, although in many areas of the US and worldwide there are populations that have adapted to the most commonly deployed resistance to P. sojae ( Rps genes. Hence, this system has received increased attention towards identifying mechanisms and molecular markers associated with partial resistance to this pathogen. Several quantitative trait loci (QTL have been identified in the soybean cultivar ‘Conrad’ that contributes to the expression of partial resistance to multiple P. sojae isolates. Results In this study, two of the Conrad QTL on chromosome 19 were dissected through sequence and expression analysis of genes in both resistant (Conrad and susceptible (‘Sloan’ genotypes. There were 1025 single nucleotide polymorphisms (SNPs in 87 of 153 genes sequenced from Conrad and Sloan. There were 304 SNPs in 54 genes sequenced from Conrad compared to those from both Sloan and Williams 82, of which 11 genes had SNPs unique to Conrad. Eleven of 19 genes in these regions analyzed with qRT-PCR had significant differences in fold change of transcript abundance in response to infection with P. sojae in lines with QTL haplotype from the resistant parent compared to those with the susceptible parent haplotype. From these, 8 of the 11 genes had SNPs in the upstream, untranslated region, exon, intron, and/or downstream region. These 11 candidate genes encode proteins potentially involved in signal transduction, hormone-mediated pathways, plant cell structural modification, ubiquitination, and basal resistance. Conclusions These findings may indicate a complex defense network with multiple mechanisms underlying these two soybean QTL conferring resistance to P. sojae. SNP markers derived from these candidate genes can contribute to fine mapping of QTL and marker assisted breeding for

  17. Development and demonstration of a gas-fired recuperative confined radiant burner (deliverable 42/43). Final report

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2003-06-01

    The objective of the project was to develop and demonstrate an innovative, efficient, low-pollutant, recuperative gas-fired IR-system (infrared radiation) for industrial processes (hereafter referred to as the CONRAD-system). The CONRAD-system is confined, so flue gases from the combustion can be kept separated from the product. The gas/air mixture to the burner is preheated by means of the flue gas, which increases the radiant efficiency of the CONRAD-system significantly over traditional gas-fired IR burners. During the first phase of the project, the CONRAD-system was designed and developed. The conducted work included a survey on suitable burner materials, modelling of the burner system, basic design of burner construction, control etc., experimental characterisation of several preprototypes and detailed design of the internal heat exchanger in the burner. The result is a cost effective burner system with a documented radiant efficiency up to 66% and low emissions (NO{sub x} and CO) all in accordance with the criteria of success set up at the start of the project. In the second phase of the project, the burner system was established and tested in laboratory and in four selected industrial applications: 1) Drying of coatings on sand cores in the automotive industry. 2) Baking of bread/cake. 3) General purpose painting/powder curing process 4. Curing of powder paint on wood components. The results from the preliminary tests Overe used to optimise the CONRAD-system, before it was applied in the industrial processes and demonstrated. However, the optimised burners manufactured for demonstration suffered from different 'infant failures', which made the installation in an industrial environment very cumbersome, and even impossible in the food industry and the automotive industry. In the latter cases realistic laboratory tests Overe carried out and the established know how reported for use when the burner problems are overcome.(au)

    A field experiment was conducted under irrigated conditions with four germplasms viz. Triticale(70-2), and wheat varieties HD 4502(durum), Kalyan Sona and Moti (aestivums) at the Indian Agricultural Research Institute Farm, New Delhi, during rabi season of 1972-73. The treatments comprised of three rates of nitrogen viz. 0,60 and 120 kg/ha and two methods of nitrogen application viz. (1) soil + foliar and (2) soil. The root distribution of the four germplasms, studied by 32 P injection technique was increased both vertically and horizontally with the addition of nitrogen. Root distribution of triticale was observed to be deep and spreading in habit, while durum proved to be shallow rooted and compact in nature. The total uptake of nitrogen was significantly increased with higher rates of nitrogen in all the germplasms. The maximum uptake of nitrogen was observed in the durum wheat. (author)

  1. Notes on the Recent History of Neuroscience in Africa

    Directory of Open Access Journals (Sweden)

    Vivienne A. Russell

    2017-11-01

    Full Text Available Neuroscience began with neuroanatomy and neurosurgery in Egypt more than 5000 years ago. Knowledge grew over time and specialized neurosurgery centers were established in north Africa in the eleventh century. However, it was not until the twentieth century that neuroscience research became established in sub-Saharan Africa. In most African countries, clinical research focused on understanding the rationale and improving treatment of epilepsy, infections, nutritional neuropathies, stroke and tumors. Significant advances were made. In the twenty-first century, African knowledge expanded to include all branches of neuroscience, contributing to genetic, biochemical and inflammatory determinants of brain disorders. A major focus of basic neuroscience research has been, and is, investigation of plant extracts, drugs and stress in animal models, providing insight and identifying potential novel therapies. A significant event in the history of African neuroscience was the founding of the Society of Neuroscientists of Africa (SONA in 1993. The International Brain Research Organization (IBRO supported SONA conferences, as well as workshops and neuroscience training schools in Africa. Thanks to their investment, as well as that of funding agencies, such as the National Institutes of Health (NIH, International Society for Neurochemistry (ISN, World Federation of Neurosurgical Societies (WFNS, World Federation of Neurology (WFN and the International League Against Epilepsy (ILAE, neuroscience research is well-established in Africa today. However, in order to continue to develop, African neuroscience needs continued international support and African neuroscientists need to engage in policy and decision-making to persuade governments to fund studies that address the unique regional needs in Africa.

  2. Ontogeny and physiognomy of the epigenetic landscape: A general model to explain developmental systems

    International Nuclear Information System (INIS)

    Tamayo Orrego, Lukas

    2013-01-01

    The epigenetic landscape is a graphic metaphor proposed by Conrad H. Waddington to explain the development of organisms and their parts. it is depicted as a wavy surface with summits and descending valleys, representing the paths followed by cells along their differentiation process, as part of organismal development. Conrad H. Waddington, regarded as the father of epigenetics, stands out for his theoretical contributions that include the notions of genetic assimilation, canalization of development and epi-genotype. These ideas were inspired by experimental works in developmental biology that lead to the discovery of the organizer in bird embryos, as well as environmentally-induced phenocopies in drosophila. In the current essay, I present an interpretation of the epigenetic landscape and related concepts that highlight the heuristic power of this model and its importance for contemporary biology. This work is a tribute to the life of C. H. Waddington, whose work is still of great significance.

    The European Commission has funded within its 6th Framework Programme a three-year project (2005–2007) called CONRAD, COordinated Network for RAdiation Dosimetry. The organizational framework for this project was provided by the European radiation Dosimetry Group EURADOS. Work Package 6 of CONRAD dealt with “complex mixed radiation fields at workplaces” and in this context it organised a benchmark exercise, which included both measurements and calculations, in a stray radiation field at a high-energy particle accelerator at GSI, Germany. The aim was to intercompare the response of several types of active detectors and passive dosemeters in a well-characterised workplace field. The Monte Carlo simulations of the radiation field and the experimental determination of the neutron spectra with various Bonner Sphere Spectrometers are discussed in Rollet et al.

    The discovery of X-rays in 1895 by Wilhelm Conrad Röntgen transformed our understanding of both the physical world and our understanding of ourselves. Traditional anatomy as shown by Andreas Vesalius was learnt from dissection of the supine deceased body. Radiology showed anatomy in the living in a manner previously not possible, and has transformed our anatomical understanding, particularly of human growth and variation.

    2002-01-01

    Recent surveys for unionid bivalves were conducted in the mainstem of the Sipsey River and headwater tributaries (Tombigbee River drainage) during the summer and autumn of 1996-1999. A total of 35 species and 22 genera were found. Museum records from the upper Sipsey, based largely on the efforts of H. H. Smith during 1910-11, raised the total number of recorded unionids in the Sipsey to 42. Smith documented 25 species in the river; however, most of his collections were made in the mid- to upper-Sipsey, which has lower diversity. The three most common recently observed species in descending order of abundance were Quadrula asperata (I. Lea, 1861), Pleurobema decisum (I. Lea, 1831), and Tritogonia verrucosa (Rafinesque, 1820). Federally listed species observed recently include Lampsilis perovalis (Conrad, 1834) (threatened), Medionidus acutissimus (I. Lea, 1831) (threatened), P. decisum (endangered), P. perovatum (Conrad, 1834) (endangered), and Potamilus inflatus (I. Lea, 1831) (threatened). Species not observed recently but recorded in prior surveys include Anodontoides radiatus (Conrad, 1834), Arcidens confragosus (Say, 1829), Plectomerus dombeyanus (Valenciennes, 1827), Q. metanevra (Rafinesque, 1820), Q. stapes (I. Lea, 1831) (federally endangered), P. taitianum (I. Lea, 1834) (federally endangered), and Toxolasma parvus (Barnes, 1823). Many, species are known recently or historically by only five or fewer recorded specimens including: A. radiatus, Elliptio arctata (Conrad, 1834), Ligumia recta (Lamarck, 1819), P. taitianum, P. inflatus, Q. aspera (Lea, 1831), Q. metanevra, Q. stapes, T. parvus, Truncilla donaciformis (I. Lea, 1828), Uniomerus tetralasmus (Say, 1831), Utterbackia imbecillis (Say, 1829), A. confragosus, and P. dombeyanus. Unlike the mussel fauna of most Alabama streams, that of the Sipsey River is still relatively intact in terms of species richness despite impacts from mining, silvicultural, and agricultural activities.

  14. Belaboring the Maritime Novel: The Nigger of the ‘Narcissus’, Sea Fiction, and Constituent Power

    Directory of Open Access Journals (Sweden)

    Brandon Jernigan

    2017-09-01

    Full Text Available In this article, I argue that Joseph Conrad’s revision of popular maritime fiction in 'The Nigger of the ‘Narcissus’' (1897 stages the anachronistic nature of romantic adventure in modernity in order to recuperate its own recognition of the revolutionary capacity of the body and collective labor. Throughout his work, Conrad participates in a range of popular genres, often engaging with, and drawing on, multiple genres in the space of a single novel. His formal flexibility at least partially accounts for his complex critical legacy as a writer who exposes the imperialist ideology in which he participates. 'The Nigger of the ‘Narcissus’', however, demands that we partially amend our notion of Conrad’s deconstructive aesthetic. This approach helps to clarify how the novella engages in critical self-reflection as it reveals the fragile constructedness of both genre and history. In adapting the genre of sea fiction, Conrad places pressure on extant tensions within the genre, especially around labor, and nearly renders the romantic adventure untenable. However, this pressure ultimately becomes an adaptive strategy to confront growing anxiety around imperial interdependency, including the rejection of commodified labor. At a moment in imperial history when the recognition of global interdependence and antagonism threatens the ideological, economic, and political underpinnings of imperialism, Conrad adapts the flexibility of sea fiction to confront this mounting pressure on the imperial consciousness and thus to reconstruct a more flexible representation of imperial relations.

  15. Modeling radiative transport in ICF plasmas on an IBM SP2 supercomputer

    1995-01-01

    At the University of Wisconsin-Madison the authors have integrated a collisional-radiative-equilibrium model into their CONRAD radiation-hydrodynamics code. This integrated package allows them to accurately simulate the transport processes involved in ICF plasmas; including the important effects of self-absorption of line-radiation. However, as they increase the amount of atomic structure utilized in their transport models, the computational demands increase nonlinearly. In an attempt to meet this increased computational demand, they have recently embarked on a mission to parallelize the CONRAD program. The parallel CONRAD development is being performed on an IBM SP2 supercomputer. The parallelism is based on a message passing paradigm, and is being implemented using PVM. At the present time they have determined that approximately 70% of the sequential program can be executed in parallel. Accordingly, they expect that the parallel version will yield a speedup on the order of three times that of the sequential version. This translates into only 10 hours of execution time for the parallel version, whereas the sequential version required 30 hours

    Full text: TR-RNR-21 is a derivative from a cross between 'IR-8' and 'TR-5', the latter being a N{sub f}-induced dwarf mutant of the salt tolerant variety SR-26-B. In initial yield evaluations at BARC during 1972-78 it gave higher yields of 54% in monsoon season and 19% in dry season over 'Jaya' and compared favourably with 'IR-8' and 'Sona'. During 1975-80, trials were conducted by the Andhra Pradesh Agricultural University (APAU), Rajendranagar and the All India Co-ordinated Rice Improvement Project (AICRIP), at Rajendranagar, Hyderabad. In these trials TR-RNR-21 was compared with 'Pankaj', 'Jaya', RP-4-14, 'Sona', 'Surekha', RNR-323341 and 'Prabhat'. Compared with the highest yielding check and all the seven checks combined, overall average yields of TR-RNR-21 were higher by 10.1 and 19.8% respectively. Since 1981, TR-RNR-21 was included in minikit trials of Andhra Pradesh State. Results from over 90 locations of the Telangana region show that mean grain yield of 3843 kg/ha was 19% more than the yield of the local checks. In view of its consistently superior performance, TR-RNR-21 was released as 'Hari' in 1987 for general cultivation in the irrigated transplanted conditions of the Telangana region of Andhra Pradesh, excepting the endemic gall midge prone areas. 'Hari' is a medium duration variety maturing within 135-140 days. It is a semi-dwarf (93 cm), erect, compact and non-lodging type with dark green foliage; anthocyanin pigment absent; grain long (10.1 mm), slender with kernel length/breadth ratio of 3.54; kernel flinty, white, translucent and non-glutinous; white belly absent; TGW 25.2 g; protein content 7.1%; bulling, milling and head recovery - 80, 74.5 and 68% respectively; cooking quality good. It is not affected seriously by blast, tungro virus, sheath blight and brown leaf spot diseases and green leaf hopper, leaf folder and stem borer insect pests. A characteristic of this variety is that the flag leaf is long, stays far above the panicle and

    Full Text Available Topic of the article is relation of the rise of modern science and religion in Western Europe in XVI-XVII Century. Author gives try to contribute to polemics unfolded around Robert Merton's study Science, Religion and Society in XVIIth Century England (1938, with two new thesis demonstrated on the basis of historical material. First, immediate significance of religion is not the main issue but relation and polemics among the Churches in the period of late Reformation, i.e., at the end of XVI Century. Here profound significance belongs to the sceptical polemics between chatolics (jesuits and protestants (Hugenots in France during the second half of the Century. For no side could afford the answer to the question of truth meaning of Holly Writt, polemisc have deepen the crisis of Christian theology in general. Thus, space is being open to the new born science of Copernicus, Kepler and Galileo as a new alternative. In keeping with that new expectation was born that mathematized science could by investigation of nature as work of God, with established natural laws provide the basis for reunion of Christianity and for moral reconstruction of Christian Commonwelth. This was a leading utopia of Newton-Leibnitz generation of XVII Century rationalists. According the second thesis, for institutionalization of science with Royal Society in London (1662 experience of toleration afforded through the civil war is more important than puritan religion. Furthermore, English puritanism, at the time of its forming in the middle o XVI Century was vividly totalitarian. But, one century latter, when Ryal Society was taking place, puritanism demonstrated well transformed character on the basis of libertarian attitude or on the path of via media. In that fashion it was really suitable as a factor in rise and establishing of modern science in England. Due to this trait, although majority of first member-team Royal Society have had open door for scientists of catholic

  19. A review of the customer lifetime value as a customer profitability measure in the context of customer relationship management

    Full Text Available Purpose: A number of customer metrics allow estimating customer profitability with methods such as the Customer Lifetime Value (CLV. However, investments in customer relationships carry the potential risk to destroy value and reduce profitability when based on incorrect estimates of customer profitability. Therefore, estimating future customer value correctly is essential to allocate marketing expenditures in the most effective way. In this article recent literature about the CLV is reviewed in order to assess its ability as a customer profitability measure. Besides the financial perspective of the CLV, non-financial perspectives such as customer advocacy, (customer or open innovation and learning have been identified to have an impact on customer profitability. How to properly estimate a customer’s value taking all relevant value creating factors, financial as well as non-financial, into account is the underlying research question.Design/methodology/approach: This research is based on the review of a number of theoretical and empirical articles published between 1990 and 2010. The aggregation of measures, key-drivers and risks of each key-perspective of the customer relationship contributes to the development of a more systematic understanding of the value creation process and provides answers to the research question. Indirect effects of the CLV as a source of value have received increasing attention in previous research but are not sufficiently accounted for by mainstream methods for valuing customers (Ryals, 2008. Therefore, the attempt to structure available knowledge on indirect effects of the CLV in its contextual setting is made.Findings: This research is concluded providing evidence that one-dimensional calculations of the CLV deliver an incomplete picture of the customer relationship and estimate customer profitability incorrectly. This supports the idea of a multidimensional CLV approach that accounts for interrelated key

    The European Commission has funded within its 6th Framework Programme a three-year project (2005-2007) called CONRAD, COordinated Network for RAdiation Dosimetry. A major task of the CONRAD Work Package 'complex mixed radiation fields at workplaces' was to organise a benchmark exercise in a workplace field at a high-energy particle accelerator where neutrons are the dominant radiation component. The CONRAD benchmark exercise took place at the Gesellschaft fuer Schwerionenforschung mbH (GSI) in Darmstadt, Germany in July 2006. In this paper, the results of the spectrometry using four extended -range Bonner sphere spectrometers of four different institutes are reported. Outside Cave A the neutron spectra were measured with three spectrometers at six selected positions and ambient dose equivalent values were derived for use in the intercomparison with other area monitors and dosemeters. At a common position all three spectrometers were used to allow a direct comparison of their results which acts as an internal quality assurance. The comparison of the neutron spectra measured by the different groups shows very good agreement. A detailed analysis presents some differences between the shapes of the spectra and possible sources of these differences are discussed. However, the ability of Bonner sphere spectrometers to provide reliable integral quantities like fluence and ambient dose equivalent is well demonstrated in this exercise. The fluence and dose results derived by the three groups agree very well within the given uncertainties, not only with respect to the total energy region present in this environment but also for selected energy regions which contribute in certain strength to the total values. In addition to the positions outside Cave A one spectrometer was used to measure the neutron spectrum at one position in the entry maze of Cave A. In this case a comparison was possible to earlier measurements.

    Full Text Available Joseph Conrad’s Heart of Darkness tells the journey of Marlow through the African jungle and his search for the European Kurtz who exploits the natives by imposing violence. It is mainly based upon Conrad’s own experience in Congo. Conrad learned how Europeans exploited and traded the natives for their own benefits during his own journey. The book is regarded as an attack on imperialism and criticizes immoral treatments of the European colonizers in Africa in the 19th century. Keith Booker states that “the book deals with issues such as imperialism, capitalism, race, and gender that were very much at the forefront of the turn-of-the century European mind. Conrad’s ambivalent treatment of these issues is extremely representative of the way they were treated in any number of European discourses of the time” (217. Besides, Chinua Achebe in his An “Image of Africa: Racism in Conrad’s Heart of Darkness” comments that “Heart of Darkness projects the image of Africa as ‘the other world’, the antithesis of Europe and therefore of civilization, a place where man’s vaunted intelligence and refinement are finally mocked by triumphant bestiality” (338. Although Achebe puts forward that the novel is in favor of colonialism, I consider that Conrad does not intend to write it to appreciate colonialism and therefore the purpose of this study is to approach Conrad’s Heart of Darkness from post-colonial perspective by taking European imperialism and colonialism over Africa into consideration in order to clarify how Conrad has deconstructed binary oppositions of colonialism by subverting the general idea of the Europeans towards Africa in the 19th century.

    This paper relates the historical discovery of X radiations in 1895 by the German Physicist Wilhelm Conrad Roendgen in his laboratory of Wurzburg University. Independently of Roendgen, several physicists such as Charles Glover Barkla, Jean Perrin or Max von Laue have tried to determine the nature of X rays. In 1912, in Cambridge (UK) William Henry and William Lawrence Bragg have used the X-ray diffraction property, discovered by Laue's team, to explore the atomic structure of crystals. The recent development of computers technology has considerably increased the automation of data collection and the analysis of complex diffraction diagrams. (J.S.). 3 refs., 3 photos

    Brousseau, Ruth Tebbets

    2009-01-01

    Foundations are often criticized for their short attention spans and inability to continue funding the toughest social problems. Homelessness among people with mental illnesses is considered among the most intractable of social issues. This paper explores the role of permanent supportive housing in reducing homelessness among the mentally ill; the role of the Corporation for Supportive Housing in developing, authenticating, and disseminating its model; and its long-term funding relationship with the Conrad N. Hilton Foundation, which has facilitated this trajectory. The paper tells the story of how long-term funding, strategically used, is making inroads into this serious mental health problem.

    Purpose: In the community of x-ray imaging, there is a multitude of tools and applications that are used in scientific practice. Many of these tools are proprietary and can only be used within a certain lab. Often the same algorithm is implemented multiple times by different groups in order to enable comparison. In an effort to tackle this problem, the authors created CONRAD, a software framework that provides many of the tools that are required to simulate basic processes in x-ray imaging and perform image reconstruction with consideration of nonlinear physical effects.Methods: CONRAD is a Java-based state-of-the-art software platform with extensive documentation. It is based on platform-independent technologies. Special libraries offer access to hardware acceleration such as OpenCL. There is an easy-to-use interface for parallel processing. The software package includes different simulation tools that are able to generate up to 4D projection and volume data and respective vector motion fields. Well known reconstruction algorithms such as FBP, DBP, and ART are included. All algorithms in the package are referenced to a scientific source.Results: A total of 13 different phantoms and 30 processing steps have already been integrated into the platform at the time of writing. The platform comprises 74.000 nonblank lines of code out of which 19% are used for documentation. The software package is available for download at http://conrad.stanford.edu. To demonstrate the use of the package, the authors reconstructed images from two different scanners, a table top system and a clinical C-arm system. Runtimes were evaluated using the RabbitCT platform and demonstrate state-of-the-art runtimes with 2.5 s for the 256 problem size and 12.4 s for the 512 problem size.Conclusions: As a common software framework, CONRAD enables the medical physics community to share algorithms and develop new ideas. In particular this offers new opportunities for scientific collaboration and

    How might political ideology help to shape an organizational field? We explore the discursive construction of the multinational hotel industry through analysis of one of its leading actors, Hilton International (HI), conceived by Conrad Hilton as a means of combatting communism by facilitating...... world peace through international trade and travel. While the politicized rhetoric employed at hotel openings reflected institutional diversity, it resonated in parallel with a strong anti-communist discourse. We show that through astute political sensemaking and sensegiving, macro-political discourse...

    Full Text Available Readings of Francis Ford Coppola's Apocalypse Now (1979 often confront the difficulty of having to privilege either its aesthetic context (considering, for instance, its relation to Conrad's Heart of Darkness [1899] or to the history of cinema or its value as a representation of the Vietnam War. In this paper, I will argue that viewing the film as a meditation on the nature and rhetoric of influence allows us to bridge this gap and provides us with valuable insights into both the film's aesthetic precursors and the circumstances of its historical setting.

    We present results on different approaches on mounted filesystems in use or under investigation at DESY. dCache, established since long as a storage system for physics data has implemented the NFS v4.1/pNFS protocol. New performance results will be shown with the most current version of the dCache server. In addition to the native usage of the mounted filesystem in a LAN environment, the results are given for the performance of the dCache NFS v4.1/pNFS in WAN case. Several commercial vendors are currently in alpha or beta phase of adding the NFS v4.1/pNFS protocol to their storage appliances. We will test some of these vendor solutions for their readiness for HEP analysis. DESY has recently purchased an IBM Sonas system. We will present the result of a thorough performance evaluation using the native protocols NFS (v3 or v4) and GPFS. As the emphasis is on the usability for end user analysis, we will use latest ROOT versions and current end user analysis code for benchmark scenarios.

    No high protein mutants of wheat have been obtained without depression of grain yield after screening a few thousand lines. The best wheat mutant identified in our programme so far is an erectoid mutant that has consistently shown about 1.5-2% points increase in protein over Kalyan sona for the last four years. Grain yield of the mutant is about 89% of the parent. No significant variation in amino composition is noted in the mutant. Preliminary analysis of over 200 macro mutants in three varieties of rice has resulted in identification of mutants with high protein content (10-22%) compared with 8.0 to 8.5% in the high yielding controls. The amino-acid composition of some of the mutant kernels do not show great deviation from the controls. All the high protein percentage mutants are lower in grain yield. Despite very high F 1 sterility in a cross involving the high protein genotype GMPR-51 and high yielding IR-8, several fertile F 2 plants resembling IR-8 have been isolated which on preliminary analysis have shown still higher protein content than GMPR-51, suggesting a transgressive mode of inheritance of this trait.

    2018-05-01

    In 1971, Manfred Eigen extended the principles of Darwinian evolution to chemical processes, from catalytic networks to the emergence of information processing at the molecular level, leading to the emergence of life. In this paper, we investigate some very general characteristics of this scenario, such as the valuation process of phenotypic traits in a high-dimensional fitness landscape, the effect of spatial compartmentation on the valuation, and the self-organized transition from structural to symbolic genetic information of replicating chain molecules. In the first part, we perform an analysis of typical dynamical properties of continuous dynamical models of evolutionary processes. In particular, we study the mapping of genotype to continuous phenotype spaces following the ideas of Wright and Conrad. We investigate typical features of a Schrödinger-like dynamics, the consequences of the high dimensionality, the leading role of saddle points, and Conrad's extra-dimensional bypass. In the last part, we discuss in brief the valuation of compartment models and the self-organized emergence of molecular symbols at the beginning of life.

    The European Commission has funded within its 6th Framework Programme a three-year project (2005-2007) called CONRAD, COordinated Network for RAdiation Dosimetry. The organizational framework for this project was provided by the European radiation Dosimetry Group EURADOS. Work Package 6 of CONRAD dealt with 'complex mixed radiation fields at workplaces' and in this context it organised a benchmark exercise, which included both measurements and calculations, in a stray radiation field at a high-energy particle accelerator at GSI, Germany. The aim was to intercompare the response of several types of active detectors and passive dosemeters in a well-characterised workplace field. The Monte Carlo simulations of the radiation field and the experimental determination of the neutron spectra with various Bonner Sphere Spectrometers are discussed in Rollet et al. (2008) and in Wiegel et al. (2008). This paper focuses on the intercomparison of the response of the dosemeters in terms of ambient dose equivalent. The paper describes in detail the detectors employed in the experiment, followed by a discussion of the results. A comparison is also made with the H*(10) values predicted by the Monte Carlo simulations and those measured by the BSS systems.

    In the event of an accidental or deliberate release of radionuclides to the environment, individual monitoring and dose assessment may be needed for large numbers of people. The consequences of such incidents are not limited by national boundaries. However, within the European Union (EU), there has not been any coordinated strategy for individual monitoring and dose assessment. CONRAD (CO-ordination Action for Radiation Dosimetry) is an EC 6 th Framework Programme Co-ordination Action sponsored by EURADOS (the European Radiation Dosimetry Group, http://www.eurados.org). The objective of Task 5.4 of Work Package 5 of the CONRAD project, coordinated by HPA (UK) and STUK (Finland), is the development of a network of people and organisations with responsibilities for emergency monitoring of emergency services personnel and members of the public. The network (named EUREMON) aims to promote sharing of information between countries on plans and arrangements for individual monitoring. It currently has 51 individual members from 22 EU countries, 8 non-EU countries and two international organisations. After it was established, the network was used in a survey of plans and arrangements for emergency personal monitoring in EU countries. Information is also being compiled on portable and transportable monitoring facilities and equipment in the EU. (author)

  13. Effects of Silver and Other Metals on the Cytoskeleton

    1997-01-01

    Directly or indirectly, trace concentrations of silver ion (Ag(+)) stabilize microtubules (Conrad, A.H., et al. Cell Motil. & Cytoskel. 27:117-132), as does taxol (Conrad, A.H., et al. J. Exp. Zool. 262:154-165), an effect with major consequences for cellular shape changes and development. Polymerization of microtubules is gravity-sensitive (Tabony and Job, Proc. Natl. Acad. Sci. USA 89:6948-6952), so trace amounts of Ag(+) may alter cellular ability to respond to gravity. If Ag electrolysis is used to purify water on NASA space vehicles, plants and animals/astronauts will be exposed continuously to Ag(+), a regimen with unknown cellular and developmental consequences. Fertilized eggs of the marine mudsnail, Ilyanassa obsoleta, are the cells in which the effects of A(+) on microtubules were discovered. They distribute visible cytoplasmic contents according to gravity and contain cytoplasmic morphogenetic determinants for heart development. The objectives are to determine if the effects of Ag(+), AU(3+), (of biosensor relevance), or Gd(3+) (inhibitor of some stretch-activated ion channels) on the cytoskeleton (in the presence and absence of mechanical loading) will affect cellular responses to gravity.

  14. Heart of Darkness and the epistemology of cultural differences

    Directory of Open Access Journals (Sweden)

    P. B. Armstrong

    1994-05-01

    Full Text Available Heart of Darkness has a long history of disagreement about whether to regard it as a daring attack on imperialism or a reactionary purveyor of colonial stereotypes. Taking Achebe’s now famous indictment and Clifford's recent praise that Conrad was an exemplary anthropologist, this article argues that Conrad is neither a racist nor an exemplary anthropologist hut a skeptical dramatist of epistemological processes. The novella has received these divergent responses because its enactment of the dilemmas entailed in understanding cultural otherness is inherently double and strategically ambiguous. The article argues that the novella is a calculated failure to depict achieved cross-cultural understanding presented to the reader through textual strategies which oscillate between affirming and denying the possibility of understanding otherness. The article acknowledges that charges such as that made by Achebe are extremely valuable because they break the aura of the text and establish reciprocity between it and its interpreters by putting them on equal terms, and concludes that a recognition of how unsettingly ambiguous the text is about the ideals of reciprocity and mutual understanding will empower us to engage in a sort of dialogue with it which Marlow never achieves with Africans or anyone else.

    Uriguen, Monica I.

    This study sought to identify the key attributes of high-quality programs with an eye toward helping developing countries such as Ecuador advance program quality. The dissertation is divided into five chapters: (1) introduction to high-quality programs; (2) literature review of attributes of high-quality programs; (3) grounded theory method (including interviews with 60 individuals) used to identify program attributes that enhance student learning; (4) findings; and (5) conclusions and recommendations. Following are the five clusters and thirteen attributes of high-quality programs that I identified: Cluster One: Highly Qualified Participants: (1) Highly Qualified Faculty, and (2) Highly Qualified Students; Cluster Two: Learning-Centered Cultures: (3) Shared Program Direction Focused on Learning, (4) Real-World Learning Experiences, (5) Reading-Centered Culture, and (6) Supportive and Risk-Taking Environment; Cluster Three: Interactive Teaching and Learning: (7) Integrative learning: Theory with Practice, Self with Subject, and (8) Exclusive Tutoring and Mentoring; Cluster Four: Connected Program Requirements: (9) Planned Breadth and Depth Course Work, and (10) Tangible Products; and Cluster Five: Adequate Resources: (11) Support for Students, (12) Support for Faculty, and (13) Support for Campus Infrastructure. The study was guided by Haworth and Conrad's (1997) "Engagement Theory of High-Quality Programs." Eleven of the attributes of high-quality programs are closely connected to Haworth and Conrad's theory and the other two attributes---real-world learning experiences and a reading-centered culture---make the signature theoretical contributions of the study. Real-world learning experiences encourage the active involvement of stakeholders in designing curricula with real-world learning experiences. The second attribute---a reading-centered culture---has never before been identified in the literature. There are four key differences between Haworth and Conrad

    The topical session was an exchange of experiences from the siting process, as performed, or planned to be performed, in the different member countries of the IGSC. The focus was on the role and use of geo-scientific arguments within the whole siting process. In particular, the objectives were to: (i) explore how members are planning or have used geo-scientific arguments to identify suitable sites for geological disposal facilities; (ii) compile what geo-scientific safety arguments have been used or are planned for use; (iii) explore how particular geo-scientific safety arguments were received by stakeholders (both technical and non-technical) in countries where the siting process is advanced; and (iv) evaluate regulatory views / experience on using geo-scientific safety arguments for siting. The following presentations were given: - The role of the geology in site selection in the US. Abraham Van Luik, Carlsbad Field Office, US Department of Energy - Nomination of scientifically suitable areas within the revised site selection process in Japan (Hiroyushi Ueda, NUMO, Japan); - The UK national geological screening exercise (Glenda Crockett, RWM, UK); - geo-scientific arguments in the early stage of siting (Sona Konopaskova, SURAO, Czech Republic); - The Use of Geoscience Data in the Early Phases of Canada's Siting Program for a Used Fuel DGR (Ben Belfadel, NWMO, Canada); - The new siting procedure in Germany and the role of geo-scientific information (Juergen Wollrath, BfS, Germany); - Geosciences within the siting process: the French experience (Emilia Huret and Guillaume Pepin, Andra, France); - Role of geo-scientific arguments in the on-going siting process in Switzerland (Juerg Schneider, Nagra, Switzerland); - Using geo-scientific argumentation for the siting process and in the construction licensing phase- experiences from Finland (Barbara Pastina, Posiva, Finland); - Role of geo-scientific arguments in siting an SNF repository in Sweden (Allan Hedin, SKB

  20. Some Problems of American Students in Mastering Persian Phonology.

    1988-12-01

    An adult learning to speak a foreign language normally retains an "accent" which may affect the intelligibility of certain sounds, but more often simply conveys the fact that the speaker is a non-native speaker. Various scholars have experimented and discussed the elements involved in a foreign accent. However, in Iran very few researchers have attempted to verify scientifically what are the phonetic and phonological aspects of an "accent." This author tried to determine whether or not a selected group of words, emphasizing stop voicing, produced by native speakers of Persian had significant phonetic and phonemic differences from those achieved by the American students. Subjects for the experiments were three groups of students, one Iranian, two American. A contrastive analysis of the Persian and the English stop consonants was made. An identical measurement test for all three groups was administered. Utilized was a Kay Sona-graph for acoustic analysis, and all spoken data from the Iranian group were compared with those of the American groups. An examination of acoustic correlates of Tehran stops produced by American students shows that the phonetically different but similar feature of /voice/ found in Tehran, Persian and English stops is intuitive to the Americans, and that the language learner cannot readily disassociate a phonological feature from habits of articulation. The results of this research support using the phonetic method for adult learners who want to improve their pronunciation ability. Further research and experimentation is necessary on the effect of the suprasegmental elements on a foreign accent and the most effective teaching materials and methods and to explore other possible techniques in the teaching process.

    To provide an overview of available sensory stimulation interventions, and their effect on persons with dementia and to present theoretical and methodological characteristics of the studies included. Different sensory stimulation interventions are used for persons with dementia to increase alertness, reduce agitation and improve quality of life. However, the effect of these interventions is not clear, neither are their characteristics. A systematic search and review of the literature with description of the content and an evaluation of theoretical and methodological approaches. Systematic searches in CINAHL, PubMed (Medline), The Cochrane library and PsycINFO. Studies included have been subject to quality assessment by means of Critical Appraisal Skills Programme. Fifty-five studies were included and thirty of these documented significant effect. The effect of the sensory stimulation interventions mainly reported on negative behaviours, except from five studies assessing quality of life and well-being. The majority of the studies had methodological limitations. The different sensory stimulation interventions were organised into eight categories: music, light therapy, acupressure/reflexology, massage/aromatherapy and doll therapy/pet therapy/toy therapy, the Sonas programme and Snoezelen. More studies are needed to clarify appropriate substantial background for the specific interventions. However, most of the studies based their interventions on a theoretical foundation. Furthermore, more research is needed to measure the effect of sensory stimulation on communication as well as quality of life. In addition, studies are to focus on whether the effect depends on the stage of dementia. Nurses are to be aware of sensory stimulation as a possible intervention to improve persons' quality of life. © 2016 John Wiley & Sons Ltd.

    Previous studies have demonstrated significant relationships among various cognitive variables such as negative cognition, self-efficacy, and social anxiety. Unfortunately, few studies focus on the role of cognition among youth, and researchers often fail to use domain-specific measures when examining cognitive variables. Therefore, the purpose of the present study was to examine domain-specific cognitive variables (i.e., socially oriented negative self-referent cognition and social self-efficacy) and their relationships to social anxiety in children and adolescents using structural equation modeling techniques. A community sample of children and adolescents (n=245; 55.9% female; 83.3% Caucasian, 9.4% African American, 2% Asian, 2% Hispanic, 2% "other," and 1.2% not reported) completed questionnaires assessing social cognition and social anxiety symptomology. Three latent variables were created to examine the constructs of socially oriented negative self-referent cognition (as measured by the SONAS scale), social self-efficacy (as measured by the SEQSS-C), and social anxiety (as measured by the SPAI-C and the Brief SA). The resulting measurement model of latent variables fit the data well. Additionally, consistent with the study hypothesis, results indicated that social self-efficacy likely mediates the relationship between socially oriented negative self-referent cognition and social anxiety, and socially oriented negative self-referent cognition yields significant direct and indirect effects on social anxiety. These findings indicate that socially oriented negative cognitions are associated with youth's beliefs about social abilities and the experience of social anxiety. Future directions for research and study limitations, including use of cross-sectional data, are discussed. © 2013.

    Despite major advances in HIV-1 treatment, the prevalence of HIV-associated neurocognitive disorders (HAND) remains a problem, particularly as individuals on suppressive treatment continue to live longer. To facilitate discussion on emerging and future directions in HAND research, a meeting was held in Durban, South Africa in March 2015 as part of the Society of Neuroscientists of Africa (SONA) conference. The objective of the meeting was to assess the impact of HIV subtype diversity on HAND and immunological dysfunction. The meeting brought together international leaders in the area of neurological complications of HIV-1 infection with special focus on the African population. Research presentations indicated that HAND was highly prevalent and that inflammatory cytokines and immune-activation played important roles in progression of neurocognitive impairment. Furthermore, children on antiretroviral therapy were also at risk for developing neurocognitive impairment. With respect to the effect of HIV-1 subtype diversity, analyses of HIV-1 clade C infection among South Africans revealed that clade C infection induced cognitive impairment that was independent of the substitution in HIV-1 Trans-Activator of Transcription (Tat; C31S). At the cellular level, a Zambian study showed that clade C infection resulted in reduced brain cell death compared with clade B infection suggesting clade specific variations in mediating brain cell injury. Furthermore, ex vivo Tat protein from clade CRF02_AG, prevalent in West/ Central Africa, exhibited reduced disruption of brain endothelium compared with clade B Tat protein. Discussions shed light on future research directions aimed at understanding biomarkers and disease mechanisms critical for HAND.

    Full Text Available This article discusses the role of social and environmental enterprises revealed in the concept of Corporate Social Responsibility (CSR and analyzed in the light of Ecological Modernization Theory (TME.The overall objective of this study is to understand CSR from the perspectiveof TME through more detailed research of a CSR program called  Clube dos Produtores [Producers Club].This program aims to influence the supply chain to adopt responsible and sustainable practices, and seeks to strengthen the small and medium producers through structured actions, such as training, qualification, and inspection, stimulating quality, innovation and productivity growth. It is conducted in parallel, in Portugal, by the Rede Sonae de Distribuição and, in Brazil, by Walmart Company. The data collection included both Countries. In Portugal, the Clube dos Produtores has emerged to combine the synergy between distribution and production and promote the development of domestic production. It takes the environment as the genesis for its creation, maintains a nationalist approach by encouraging the consumption of domestic products, and recognizes consumer pressure as the force for continuous innovation of products and services. In addition, it reconciles tradition and modernity through products supported by different generations. In Brazil, the Club is founded on the sustainability discourse; the customer awareness about environmental issues was not captured in the research; the producers innovations result from their own initiatives to participate in fairs or from direct contact with consumers; the dialogue between tradition and modernity occurs primarily through the entrepreneurial capacity of the producers and less direct intervention by Walmart.

    Dose assessment procedures for cosmic radiation exposure of aircraft crew have been introduced in most European countries in accordance with the corresponding European directive and national regulations. However, the radiation exposure due to solar particle events is still a matter of scientific research. Here we describe the European research project CONRAD, WP6, Subgroup-B, about the current status of available solar storm measurements and existing models for dose estimation at flight altitudes during solar particle events leading to ground level enhancement (GLE). Three models for the numerical dose estimation during GLEs are discussed. Some of the models agree with limited experimental data reasonably well. Analysis of GLEs during geomagnetically disturbed conditions is still complex and time consuming. Currently available solar particle event models can disagree with each other by an order of magnitude. Further research and verification by on-board measurements is still needed. (authors)

    On 8 March 2015 Europa passed nearly centrally in front of Io. The Large Binocular Telescope observed this event in dual-aperture AO-corrected Fizeau interferometric imaging mode using the mid-infrared imager LMIRcam operating behind the Large Binocular Telescope Interferometer (LBTI) at a broadband wavelength of 4.8 μm (M-band). Occultation light curves generated from frames recorded every 123 milliseconds show that both Loki and Pele/Pillan were well resolved. Europa's center shifted by 2 kilometers relative to Io from frame-to-frame. The derived light curve for Loki is consistent with the double-lobed structure reported by Conrad et al. (2015) using direct interferometric imaging with LBTI.

    Results of the qualitative analysis show that Agnes high gravity and magnetic association is mainly caused by a near surface igneous intrusion of NW orientation. Quantitatively, regional models indicate a normal continental type of crust, which is divided into upper and lower by the Conrad surface (21.5–22 km. The crust–mantle interface lies at 32–33 km meanwhile the magnetic crust reaches a depth of 16 km. Local models reveal that the basement rocks north and south of the Agnes high were offset by some 6–8 km and 3–4.5 km, respectively. Statistically, the area was controlled by two main old trends; the most prevailing WNW to NNW (East African and the less abundant ENE (Syrian Arc trends. These two principal trends almost have its doubtless impact on preservation of possible accumulations.

    It is now well established that x-rays were accidentally discovered by Prof. Wilhelm Conrad Roentgen on the afternoon of November 8, 1895, when he was experimenting with cathode rays in the Physics Department, University of Wurzburg, Wurzburg, Germany. In spite of suggestions by several of his friends, Roentgen politely declined to patent his discovery. Consequently, x-rays could be put to immediate use for a variety of applications, and primarily in medicine to visualise the internal structures of the human body, as also for diagnosis and treatment of diseases. Roentgen was the first recipient of the Nobel prize in Physics, which was established in 1901. Roentgen donated the entire Nobel prize money to the University of Wurzburg for scientific activities. Such were the greatness and humanitarian approach of Roentgen, and now x-rays have become a household name. (author). 3 refs., 3 ills

    The advances in equipment and knowledge related to radiology are occurring at an astonishingly rapid rate. On November 8, 1895, William Conrad Roentgen discovered x-rays. In 1972, Godfrey Hounsfield and George Ambrose introduced computec tomography at a meeting of the British Institute of Radiology. In the same year, Paul Lauterbur published the idea of spatially resolving nuclear magnetic resonance samples, naming it zeugmatography. In 1977, Waldo Hinshaw and co-workers published a magnetic resonance image of a human hand and wrist, and by 1981 several centres were obtaining clinical magnetic resonance (MR) images. In a very short time, magnetic resonance imaging (MRI) has gained acceptance as a clinically useful imaging tool. (author)

    Christensen, Bent Jesper; Dahl, Christian Møller; Iglesias, Emma M.

    A new semiparametric estimator for an empirical asset pricing model with general nonpara- metric risk-return tradeoff and a GARCH process for the underlying volatility is introduced. The estimator does not rely on any initial parametric estimator of the conditional mean func- tion, and this feature...... facilitates the derivation of asymptotic theory under possible nonlinearity of unspecified form of the risk-return tradeoff. Besides the nonlinear GARCH-in-mean effect, our specification accommodates exogenous regressors that are typically used as conditioning variables entering linearly in the mean equation...... with the fully parametric approach and the iterative semiparametric approach using a parametric initial esti- mate proposed by Conrad and Mammen (2008). An empirical application to the daily S&P 500 stock market returns suggests that the linear relation between conditional expected return and conditional...

  11. Plasma ion implantation technology for broad industrial application

    Deb, D.; Siambis, J.; Symons, R.

    1994-01-01

    The recently invented Plasma Ion Implantation (PII) process (1987) [J. R. Conrad, U.S. Patent No. 764394 (August 16, 1988)] is currently under intense industrial engineering investigation and development. A critical component of PII for broad industrial utilization is the availability of an efficient modulator system that applies the high voltage pulse to the workpiece. A modulator technology assessment and selection is carried out. The requirements of the PII process favor the selection of a hard-tube modulator. The PII process favors the application of beam switch tube technology such as the Litton L-5012 and L-5097. These Litton tubes have already been selected by LANL and utilized in their pilot engineering demonstration experiment with GM and the University of Wisconsin. The performance, physical operation, and potential enhancements of the Litton beam switch tubes L-5012 and L-5097 will be discussed in connection with the requirements of the emerging plasma ion implantation industrial modulator technology

    Hardly any other discovery of the nineteenth century did have such an impact on science and technology as Wilhelm Conrad Röntgen’s seminal find of the X-rays. X-ray tubes soon made their way as excellent instruments for numerous applications in medicine, biology, materials science and testing, chemistry and public security. Developing new radiation sources with higher brilliance and much extended spectral range resulted in stunning developments like the electron synchrotron and electron storage ring and the freeelectron laser. This handbook highlights these developments in fifty chapters. The reader is given not only an inside view of exciting science areas but also of design concepts for the most advanced light sources. The theory of synchrotron radiation and of the freeelectron laser, design examples and the technology basis are presented. The handbook presents advanced concepts like seeding and harmonic generation, the booming field of Terahertz radiation sources and upcoming brilliant light sources dri...

    Biomedical imaging is a relatively young discipline that started with Conrad Wilhelm Roentgen’s discovery of the x-ray in 1885. X-ray imaging was rapidly adopted in hospitals around the world. However, it was the advent of computerized data and image processing that made revolutionary new imaging modalities possible. Today, cross-sections and three-dimensional reconstructions of the organs inside the human body is possible with unprecedented speed, detail and quality. This book provides an introduction into the principles of image formation of key medical imaging modalities: X-ray projection imaging, x-ray computed tomography, magnetic resonance imaging, ultrasound imaging, and radionuclide imaging. Recent developments in optical imaging are also covered. For each imaging modality, the introduction into the physical principles and sources of contrast is provided, followed by the methods of image formation, engineering aspects of the imaging devices, and a discussion of strengths and limitations of the modal...

    2012-01-01

      Heart of Darkness was written by Joseph Conrad and published as a whole in 1902. The story begins on a British ship“the Nellie”moored on the coast of the Thames. It mainly talks about what Marlow sees and thinks when he begins his journey up to the Congo Riveres and reveals a turning process of a white colonizer called Kurts who is at the very beginning, an idealistic white colonizer trying to bring“civilization”and“progress”to the Africa but in the end falls into a greedy, cruel person. The novel, on the one hand, describes the terrible life of African peple and reveals the tyranne, greed of western colo⁃nism and stong racism; and on the other hand, it also shows readers a strong orientalism towards the Africa. So my purpose of the paper is to analyse how Orientalism is revealed in the Heart of Darkness.

    Physics offers a cross-discipline perspective to understanding other subjects. The purpose of this paper is to provide examples of physics in literature that physics and astronomy teachers can use to give students an indication of the relevance of science as depicted in the humanities. It is not possible to cite the thousands of examples available. I have tried to select authors whom students would be reading in high school and in college undergraduate English classes: in particular Joseph Conrad, Samuel Taylor Coleridge, William Shakespeare, H. G. Wells, Fyodor Dostoevsky, Norman Mailer, and an author currently in vogue, Dan Brown. I am sure many reading this article will come up with their own examples.

    Brown, I.G.; Yu, K.M.; Godechot, X.

    1991-04-01

    We describe here a novel technique for surface modification in which metal plasma is employed and by which various blends of plasma deposition and ion implantation can be obtained. The new technique is a variation of the plasma immersion technique described by Conrad and co-workers. When a substrate is immersed in a metal plasma, the plasma that condenses on the substrate remains there as a film, and when the substrate is then implanted, qualitatively different processes can follow, including' conventional' high energy ion implantation, recoil implantation, ion beam mixing, ion beam assisted deposition, and metallic thin film and multilayer fabrication with or without species mixing. Multiple metal plasma guns can be used with different metal ion species, films can be bonded to the substrate through ion beam mixing at the interface, and multilayer structures can be tailored with graded or abrupt interfaces. We have fabricated several different kinds of modified surface layers in this way. 22 refs., 4 figs

  17. Combining Radiation Epidemiology With Molecular Biology-Changing From Health Risk Estimates to Therapeutic Intervention.

    Abend, Michael; Port, Matthias

    2016-08-01

    The authors herein summarize six presentations dedicated to the key session "molecular radiation epidemiology" of the ConRad meeting 2015. These presentations were chosen in order to highlight the promise when combining conventional radiation epidemiology with molecular biology. Conventional radiation epidemiology uses dose estimates for risk predictions on health. However, combined with molecular biology, dose-dependent bioindicators of effect hold the promise to improve clinical diagnostics and to provide target molecules for potential therapeutic intervention. One out of the six presentations exemplified the use of radiation-induced molecular changes as biomarkers of exposure by measuring stabile chromosomal translocations. The remaining five presentations focused on molecular changes used as bioindicators of the effect. These bioindicators of the effect could be used for diagnostic purposes on colon cancers (genomic instability), thyroid cancer (CLIP2), or head and neck squamous cell cancers. Therapeutic implications of gene expression changes were examined in Chernobyl thyroid cancer victims and Mayak workers.

    Costa, Rossella; Frezza, Giulia

    2014-01-01

    The origin of epigenetics has been traditionally traced back to Conrad Hal Waddington's foundational work in 1940s. The aim of the present paper is to reveal a hidden history of epigenetics, by means of a multicenter approach. Our analysis shows that genetics and embryology in early XX century--far from being non-communicating vessels--shared similar questions, as epitomized by Thomas Hunt Morgan's works. Such questions were rooted in the theory of epigenesis and set the scene for the development of epigenetics. Since the 1950s, the contribution of key scientists (Mary Lyon and Eduardo Scarano), as well as the discussions at the international conference of Gif-sur-Yvette (1957) paved the way for three fundamental shifts of focus: 1. From the whole embryo to the gene; 2. From the gene to the complex extranuclear processes of development; 3. From cytoplasmic inheritance to the epigenetics mechanisms.

    Within the framework of the European project CONRAD (Coordinated Network for Radiation Dosimetry, contract FP6-12684) coordinated by EURADOS (European Radiation Dosimetry group), WP4 was devoted to numerical dosimetry under the title 'Uncertainty assessment in computational dosimetry: an intercomparison of approaches'. Within this activity, a working group sent a list of eight exercises, dealing with radiation transport of photons, neutrons, protons and electrons, to be solved by the international community. This paper presents exercise number 4, dealing with the calculation of air kerma for a {sup 137}Cs beam. This problem was aimed at estimating the components of the uncertainty on the air kerma which cannot be measured, namely those due to geometrical data such as the source location, the diameter of the collimator, the material density, etc. 12 institutes of 10 different countries took part in this work, showing the interest in this proposal.

    Artistically Nostromo is arguably the most ambitious of Joseph Conrad's novels. It is also without a doubt the most explicitly political in that it openly engages with the question of how capitalism, imperialism, and revolution affect the human consciousness.

    Auriferae (1593); and it raises the question of whether this could be the possible missing link to Jung's subsequent research in Alchemy and Hermetic Philosophy in the years to come. It is argued that here was the beginning of Jung's quest for the Aurora consurgens, the publication of which concludes...... the Mysterium Conuinctionis more than twenty years later. It is further maintained that this choice of the Aurora is a profound expression of Jung's ambition to revitalize the past from within the individual, and helps explain Jung's deep concern with the welfare and future of modern society.......The paper focuses on the year 1929 when Jung published ‘A European commentary’ to Richard Wilhelm's German translation of the Taoist text The Secret of the Golden Flower.

    Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common psychiatric disorders among children and most Western countries have witnessed an increase during the past two decades. Its core symptoms are inattention. hyperactivity, and impulsivity. Most children are diagnosed with ADHD...... parenting courses. Research has found that such interventions, especially if initiated early in the child's life, can strengthen the child's cognitive, emotional and social development (Kooij 2013; Smith, Barkley & Shapiro 2006; Pfiffer, Barkley & Du Paul 2006).

    Full Text Available An IAEA project to update the Neutron Standards is near completion. Traditionally, the Thermal Neutron Constants (TNC evaluated data by Axton for thermal-neutron scattering, capture and fission on four fissile nuclei and the total nu-bar of 252Cf(sf are used as input in the combined least-square fit with neutron cross section standards. The evaluation by Axton (1986 was based on a least-square fit of both thermal-spectrum averaged cross sections (Maxwellian data and microscopic cross sections at 2200 m/s. There is a second Axton evaluation based exclusively on measured microscopic cross sections at 2200 m/s (excluding Maxwellian data. Both evaluations disagree within quoted uncertainties for fission and capture cross sections and total multiplicities of uranium isotopes. There are two factors, which may lead to such difference: Westcott g-factors with estimated 0.2% uncertainties used in the Axton's fit, and deviation of the thermal spectra from Maxwellian shape. To exclude or mitigate the impact of these factors, a new combined GMA fit of standards was undertaken with Axton's TNC evaluation based on 2200 m/s data used as a prior. New microscopic data at the thermal point, available since 1986, were added to the combined fit. Additionally, an independent evaluation of TNC was undertaken using CONRAD code. Both GMA and CONRAD results are consistent within quoted uncertainties. New evaluation shows a small increase of fission and capture thermal cross sections, and a corresponding decrease in evaluated thermal nubar for uranium isotopes and 239Pu.

    Characterization of a deep aquifer is the main target of the research work presented here. The study area is located in the central part of Sinai, an extremely arid region in Egypt. Different geophysical methods, including resistivity, gravity, and magnetic, were applied in the study area for groundwater exploration. Fifteen vertical electrical soundings were measured with current electrode spacing ranging from AB = 10 m to AB= 6000 m, in order to detect the deep aquifer in the study area. The resistivity 1D models were used to construct a geoelectrical cross-section to define the subsurface stratigraphy units, including the water-bearing aquifer. The geoelectrical cross-sections showed that the upper part of the subsurface consists of four geoelectric units. The deep aquifer is lodged by the last unit constituted of Nubian sandstone (Lower Cretaceous deposits). The depth of the top of the Nubian sandstone ranges between 300 and 1000 m. The resistivity of the aquifer varies between 60 and 400 ohm-m, indicating the existence of good quality water. Gravity and ground magnetic (total magnetic field) measurements were made at one hundred and fifty stations. The combined interpretation of the magnetic and gravity data allowed the determination of the depth of the surface of the granitic basement and the depth of the Conrad surface. The results of the modeling indicate that the basement lies between 1500 and 3150 m depth and that the Conrad surface (interface between the granitic and basaltic layer) is ranging from 7130 to 8780 m. Structural elements (mostly normal faults) NW-SE, N-S and NE-SW oriented, have been detected. These structures are associated with vertical movements that might have controlled the sedimentation of the uppermost geological formations. (author)

    Purpose: To develop a procedure for including dose constraints in convex programming-based approaches to treatment planning, and to support dynamic modification of such constraints during planning. Methods: We present a mathematical approach that allows mean dose, maximum dose, minimum dose and dose volume (i.e., percentile) constraints to be appended to any convex formulation of an inverse planning problem. The first three constraint types are convex and readily incorporated. Dose volume constraints are not convex, however, so we introduce a convex restriction that is related to CVaR-based approaches previously proposed in the literature. To compensate for the conservatism of this restriction, we propose a new two-pass algorithm that solves the restricted problem on a first pass and uses this solution to form exact constraints on a second pass. In another variant, we introduce slack variables for each dose constraint to prevent the problem from becoming infeasible when the user specifies an incompatible set of constraints. We implement the proposed methods in Python using the convex programming package cvxpy in conjunction with the open source convex solvers SCS and ECOS. Results: We show, for several cases taken from the clinic, that our proposed method meets specified constraints (often with margin) when they are feasible. Constraints are met exactly when we use the two-pass method, and infeasible constraints are replaced with the nearest feasible constraint when slacks are used. Finally, we introduce ConRad, a Python-embedded free software package for convex radiation therapy planning. ConRad implements the methods described above and offers a simple interface for specifying prescriptions and dose constraints. Conclusion: This work demonstrates the feasibility of using modifiable dose constraints in a convex formulation, making it practical to guide the treatment planning process with interactively specified dose constraints.

    Seamounts are topographically and oceanographically complex features with environmental characteristics, including substrate types, carbon flux, and current patterns, that vary greatly within and among seamounts. While seamounts are reputed to be oases and biodiversity hotspots, comparisons across multiple spatial scales of a seamount chain have yet to be explored. Along the margins of the Caribbean Sea basin, numerous seamounts punctuate the seafloor. In 2013 and 2014, we investigated the deep-sea benthic community ecology at Noroît, Dog, and Conrad Seamounts and nearby ridge, bank, and rift environments at depths ranging from 630 to 2930 m. Sediment push cores were collected to quantify macrofaunal (> 300 μm) density, diversity, community composition, grain size, and organic content. In addition, environmental data collected from CTDs and extracted from high resolution multibeam mapping efforts (e.g. slope, rugosity, roughness, slope orientation), allowed us to evaluate the role of microhabitats in structuring these communities. Preliminary results indicate that macrofaunal density across all sites decreased with depth in both seamount and non-seamount sediments, with the highest densities occurring in non-seamount environments. However, macrofaunal density patterns varied on individual seamounts. Macrofaunal densities on shallow seamounts (Conrad and Dog) increased with depth, whereas densities decreased with depth on the deeper Noroît seamount. The relationship between environmental parameters and macrofaunal community structure and biodiversity varied among seamounts and non-seamount environments. This study represents the first investigation of seamount infauna in the region and places this baseline information on seamount faunal biodiversity, spatial distribution of taxa, and overall ecology into a broader biogeographic context.

  10. Improvement of Sodium Neutronic Nuclear Data for the Computation of Generation IV Reactors

    2011-01-01

    The safety criteria to be met for Generation IV sodium fast reactors (SFR) require reduced and mastered uncertainties on neutronic quantities of interest. Part of these uncertainties come from nuclear data and, in the particular case of SFR, from sodium nuclear data, which show significant differences between available international libraries (JEFF-3.1.1, ENDF/B-VII.0, JENDL-4.0). The objective of this work is to improve the knowledge on sodium nuclear data for a better calculation of SFR neutronic parameters and reliable associated uncertainties. After an overview of existing 23 Na data, the impact of the differences is quantified, particularly on sodium void reactivity effects, with both deterministic and stochastic neutronic codes. Results show that it is necessary to completely re-evaluate sodium nuclear data. Several developments have been made in the evaluation code Conrad, to integrate new nuclear reactions models and their associated parameters and to perform adjustments with integral measurements. Following these developments, the analysis of differential data and the experimental uncertainties propagation have been performed with Conrad. The resolved resonances range has been extended up to 2 MeV and the continuum range begins directly beyond this energy. A new 23 Na evaluation and the associated multigroup covariances matrices were generated for future uncertainties calculations. The last part of this work focuses on the sodium void integral data feedback, using methods of integral data assimilation to reduce the uncertainties on sodium cross sections. This work ends with uncertainty calculations for industrial-like SFR, which show an improved prediction of their neutronic parameters with the new evaluation. (author) [fr

    The thesis has been motivated by a wish to increase the uncertainty knowledge on nuclear data, for safety criteria. It aims the cross sections required by core calculation for sodium fast reactors (SFR), and new tools to evaluate its.The main objective of this work is to provide new tools in order to create coherent evaluated files, with reliable and mastered uncertainties. To answer those problematic, several methods have been implemented within the CONRAD code, which is developed at CEA of Cadarache. After a summary of all the elements required to understand the evaluation world, stochastic methods are presented in order to solve the Bayesian inference. They give the evaluator more information about probability density and they also can be used as validation tools. The algorithms have been successfully tested, despite long calculation time. Then, microscopic constraints have been implemented in CONRAD. They are defined as new information that should be taken into account during the evaluation process. An algorithm has been developed in order to solve, for example, continuity issues between two energy domains, with the Lagrange multiplier formalism. Another method is given by using a marginalization procedure, in order to either complete an existing evaluation with new covariance or add systematic uncertainty on an experiment described by two theories. The algorithms are well performed along examples, such the 238 U total cross section. The last parts focus on the integral data feedback, using methods of integral data assimilation to reduce the uncertainties on cross sections. This work ends with uncertainty reduction on key nuclear reactions, such the capture and fission cross sections of 238 U and 239 Pu, thanks to PROFIL and PROFIL-2 experiments in Phenix and the Jezebel benchmark.

Morden) as 5th and 6th crops. respectively, grown on an inceptisol amended with normal sewage sludge (NSS) and irradiated sewage sludge (ISS) at the application rates of 0, 2, 4, 6 and 8 t ha -1 . Results indicated no significant differences in the dry matter yield (DMY) between the various treatments of either shoot or grain of both the crops. In general DMY of shoot was more than that of grain and also the DMY of wheat crop was more than that of sunflower. Data on the N, P, K contents of the two crops revealed no significant differences at the different treatments of both NSS and ISS; however, the different levels of NSS and ISS significantly enhanced the shoot N content of wheat, whereas grain P content of sunflower was significantly reduced. Nitrogen and P uptake in grain was higher than that of shoot of both the crops, but reverse was true for K. In general, N and P contents were higher in sunflower crop as compared to wheat crop and the opposite trend was obtained for K content. Results on the micronutrient contents of the two crops indicated an enhancement in the Cu and Zn contents of wheat crop by both NSS and ISS at different rates of application. Copper and Mn contents in wheat shoot were higher than that of wheat grain and the reverse was obtained for Zn. Copper, Zn and Mn contents of wheat shoot were lower than that of previous crops. Data on the micronutrient contents of sunflower crop indicated no significant differences between the different levels of NSS and ISS application. Manganese content of sunflower grain was higher than that of shoot and the opposite trend was noticed for Cu and Zn. Soil analysis after harvest of wheat crop indicated a significant enhancement in the soil characteristics such as pH, organic C and total N due to various levels of NSS and ISS

Furosemide is used in prevention, or treatment, of acute renal dysfunction. This study was conducted to evaluate the protective effects of intra- and early postoperative furosemide infusion on preventing acute renal dysfunction in elective adult cardiac surgery. Methods: Eighty-one patients, candidates of elective cardiac surgery, were enrolled in this study in either the furosemide (n=41 or placebo (n=40 group. Furosemide (2 mg/h or 0.9% saline was administered and continued up to 12 hours postoperatively. We measured serum creatinine (Scr at preoperative and on the second and fifth postoperative days. Then calculated estimated glomerular filtration rate (eGFR at these times. An increase in Scr of >0.5 mg/dL and/or >25%–50%, compared to preoperative values, was considered as acute kidney injury (AKI. In contrast, an increase in Scr by >50% and/or the need for hemodialysis was regarded as acute renal failure (ARF. At the end we compared the AKI or ARF incidence between the two groups. Results: On the second and fifth postoperative days, Scr was lower, and the eGFR was higher in the furosemide group. AKI incidence was similar in the two groups (11 vs 12 cases; P-value 0.622; however, ARF rate was lower in furosemide group (1 vs 6 cases; P-value 0.044. During the study period, Scr was more stable in the furosemide group, however in the placebo group, Scr initially increased and then decreased to its preoperative value after a few days.

The modern directions of development of economic activity of the organizations of a food and agricultural profile to some extent already use integration advantages, however thus there are insufficiently balanced target interests of the interfaced participants of agro-industrial production that is directly or indirectly reflected in methods and instruments of organizational management. For mitigation of this situation and leveling of influence of factors of imbalance of management processes, it is offered to reform modern system of the business relations in agrarian and industrial complex on the basis of creation of the polycluster formations possessing the following key properties: territorial concentration of subjects; intra cluster competition; stability of economic relations; politsentrichnost; sona-pravlenny development of subjects; manifestation of a positive synergy.

    Full Text Available Polythoridae comprise a widespread group of species in the New World tropics, but little is known about their behavior or life history. Here, we described the reproductive behavior of Amazonian Chalchopteryx rutilans, using mark-recapture techniques. Males were resident and territorial, though we found disputes (complex flight manoeuvres to be rare. Trunks (rotting wood were important to male persistence in sites, as these are the locations preferred by females for oviposition. The mating system of C. rutilans may be comparable to the resource limitation category, described by Conrad & Pritchard (1992, where males cannot control female access to oviposition sites. So, female choice becomes important and apparently, the observed displays (in which males flash the coppery coloration of their hind wings may be related to attraction of females to territories, as in a lek system.A família Polythoridae compreende diversas espécies tropicais, das quais muito pouco se conhece sobre o comportamento ou história de vida.

    Full Text Available Andrea Ries Thurman, Meredith R Clark, Jennifer Hurlburt, Gustavo F Doncel CONRAD, Department of Obstetrics and Gynecology, Eastern Virginia Medical School, Norfolk, VA, USA Abstract: There is a renewed interest in delivering pharmaceutical products via intravaginal rings (IVRs. IVRs are flexible torus-shaped drug delivery systems that can be easily inserted and removed by the woman and that provide both sustained and controlled drug release, lasting for several weeks to several months. In terms of women's health care products, it has been established that IVRs effectively deliver contraceptive steroids and steroids for the treatment of postmenopausal vaginal atrophy. A novel application for IVRs is the delivery of antiretroviral drugs for the prevention of human immunodeficiency virus (HIV genital infection. Microbicides are antiviral drugs delivered topically for HIV prevention. Recent reviews of microbicide IVRs have focused on technologies in development and optimizing ring design. IVRs have several advantages, including the ability to deliver sustained drug doses for long periods of time while bypassing first pass metabolism in the gut. IVRs are discreet, woman-controlled, and do not require a trained provider for placement or fitting. Previous data support that women and their male sexual partners find IVRs highly acceptable. Multipurpose prevention technology (MPT products provide protection against unintended/mistimed pregnancy and reproductive tract infections, including HIV. Several MPT IVRs are currently in development. Early clinical testing of new microbicide and MPT IVRs will require a focus on safety, pharmacokinetics and pharmacodynamics. Specifically, IVRs will have to deliver tissue concentrations of drugs that are pharmacodynamically active, do not cause mucosal alterations or inflammation, and do not change the resident microbiota. The emergence of resistance to antiretrovirals will need to be investigated. IVRs should not

    Interventional radiological procedures can lead to significant radiation doses to patients and to staff members. In order to evaluate the personal doses with respect to the regulatory dose limits, doses measured by dosimeters have to be converted to effective doses (E). Measurement of personal dose equivalent Hp(10) using a single unshielded dosimeter above the lead apron can lead to significant overestimation of the effective dose, while the measurement with dosimeter under the apron can lead to underestimation. To improve the accuracy, measurements with two dosimeters, one above and the other under the apron have been suggested ( d ouble dosimetry ) . The ICRP has recommended that interventional radiology departments develop a policy that staff should wear two dosimeters. The aim of this study was to review the double dosimetry algorithms for the calculation of effective dose in high dose interventional radiology procedures. The results will be used to develop general guidelines for personal dosimetry in interventional radiology procedures. This work has been carried out by Working Group 9 (Radiation protection dosimetry of medical staff) of the CONRAD project, which is a Coordination Action supported by the European Commission within its 6th Framework Program.(author)

  7. The changing role of health physicists as reflected by changes in professional health physics training courses

    1996-01-01

    Health Physics is a profession with long, honourable traditions; and this paper could be subtitled 'Health Physics - The First 100 Years'. The discovery of X-rays by Conrad Roentgen in 1895 and of natural radioactivity by Henri Becquerel in 1896, was followed two years later by the isolation of radium by Marie and Pierre Curie and then during the last years of the nineteenth century, by explosive world wide growth in the utilisation of both these new discoveries for medical diagnostic and therapeutic purposes The fact that these new medical tools carried associated risks was very quickly learned. Physicians who most enthusiastically adopted them often experienced severe skin injuries to heavily exposed digits, and there are numerous photographs of the hands of such individuals after experiencing several amputations. Regrettably mans ultimately fatal radiation induced cancers also began to appear before the end of the last century, by the first world par there were 200 of these and the death toll already exceeded 50. In the face of this two edged weapon it is not surprising that many of the physicians and medical physicists working in this area turned a great deal of their attention from the exploitation of the new technologies to the protection of their colleagues. These individuals were the pioneer health physicists and. although this name was not used at the time, their background experience in both medicine and physics laid scientific foundations for the new discipline which have remained its keystone ever since.

    High angular resolution from ground-based observatories stands as a key technology for advancing planetary science. In the window between the angular resolution achievable with 8-10 meter class telescopes, and the 23-to-40 meter giants of the future, LBT provides a glimpse of what the next generation of instruments providing higher angular resolution will provide. We present first ever resolved images of an Io eruption site taken from the ground, images of Io's Loki Patera taken with Fizeau imaging at the 22.8 meter LBT [Conrad, et al., AJ, 2015]. We will also present preliminary analysis of two data sets acquired during the 2015 opposition: L-band fringes at Kurdalagon and an occultation of Loki and Pele by Europa (see figure). The light curves from this occultation will yield an order of magnitude improvement in spatial resolution along the path of ingress and egress. We will conclude by providing an overview of the overall benefit of recent and future advances in angular resolution for planetary science.

    Neutron imaging is a non-destructive investigation method with a fast growing application field in materials research and fundamental science. The method is used broadly in the cultural heritage research as complementary technique to x-ray imaging. The ability of neutron beam to transmit thick layers of metal and the sensitivity to light elements makes the technique unique for detection of organic substances in metal and stone matrices. The high penetration power of neutrons allows for investigation of samples with real dimensions of about 100 cm3. The neutron imaging in cultural heritage helps to provide information about manufacturing processes and material properties which is very important for further restoration and conservation of the objects. The development of new methods like energy selective imaging and grating interferometry and the application of autoradiography increase the potential of the method for characterization of cultural heritage samples. The neutron tomography instrument CONRAD has been in operation since 2005 at the Hahn-Meitner research reactor at Helmholtz-Zentrum Berlin (HZB). Over the last 5 years, significant development work has been performed to expand the radiographic and tomographic capabilities of the beamline. New techniques have been implemented, including imaging with polarized neutrons, Bragg-edge mapping, high-resolution neutron imaging and grating interferometry. These methods together with the autoradiography have been provided to the user community as tools to help address scientific problems particularly in the field of cultural heritage and palaeontology. Descriptions and parameters of the facilities are given

  10. Forms of Affect, Relationality, and Periodical Encounters, or ‘Pine-Apple for the Million’

    2016-07-01

    Full Text Available The social, economic, intellectual, cultural, and material relations that comprise periodical encounters have been attended to in analyses that invoke the concept of the network, what Nathan Hensley has described as a ‘chain of visible or material interactions among human and nonhuman entities’. The affective dimensions of these relations, however, are neither material nor always visible, yet they are fundamental to all such interactions. This article argues that the periodical’s capacity to communicate, the contours, scope, and effects of that capacity, and in particular its genre traction, are everywhere underscored by a relationality that is charged with affect and emotions, shaped by what Raymond Williams famously described as ‘structures of feeling’. My focus on the haptic currents that drive periodical exchanges (taking examples from George Eliot at the Cornhill Magazine, Joseph Conrad in Blackwood’s Edinburgh Magazine, and James Joyce in the Irish Homestead follows from important theorizations of the unique affordances of this ‘most time-oriented of print forms’ (Beetham. Affect, feelings, and emotive responses are messy and cannot be pressed into a discrete methodology, but when considering the open-ended, multi-textured, serial form that is the periodical, there is something to be gained, I suggest, from trying to understand the operations of affect, its openness, its aleatoric potential, and its emotion-based effects.

    The National Oceanic and Atmospheric Administration (NOAA) recently announced the development of El Nino conditions in the tropical Pacific Ocean near the South American coastline. Scientists detected a 4 F increase in the sea-surface temperatures during February. Conrad C. Lautenbacher, NOAA administrator and Under Secretary of Commerce for Oceans and Atmosphere, indicated that this warming is a sign that the Pacific Ocean is heading toward an El Nino condition. Although it is too early to predict how strong the El Nino will become or the conditions it will bring to the United States, Lautenbacher said that the country is likely to feel the effects as soon as midsummer (Figure 1). During the last El Nino in 1997-1998, the United States experienced strong weather impacts. Even though researchers don't understand what causes the onset of El Nino, they do recognize what to expect once development has begun. Scientists can monitor the development of El Nino through NOAA's advanced global climate monitoring system of polar-orbiting satellites and 72 ocean buoys moored across the equator in the Pacific Ocean. The resulting measurements of surface meteorological parameters and upper ocean temperatures are made available to scientists on a real-time basis, allowing for timely monitoring and predictions. This complex monitoring array enabled NOAA to predict the 1997-1998 El Nino six months in advance

    2017-11-01

    This paper focuses on the use of X-rays in their largest field of application: medical diagnostic imaging and image-guided therapy. For this purpose, vacuum electronics in the form of X-ray tubes as the source of bremsstrahlung (braking radiation) have been the number one choice for X-ray production in the range of photon energies between about 16 keV for mammography and 150 keV for general radiography. Soft tissue on one end and bony structures on the other are sufficiently transparent and the contrast delivered by difference of absorption is sufficiently high for this spectral range. The dominance of X-ray tubes holds even more than 120 years after Conrad Roentgen's discovery of the bremsstrahlung mechanism. What are the specifics of current X-ray tubes and their medical diagnostic applications? How may the next available technology at or beyond the horizon look like? Can we hope for substantial game changers? Will flat panel sources, less expensive X-ray "LED's", compact X-ray Lasers, compact synchrotrons or equivalent X-ray sources appear in medical diagnostic imaging soon? After discussing the various modalities of imaging systems and their sources of radiation, this overview will briefly touch on the physics of bremsstrahlung generation, key characteristics of X-ray tubes, and material boundary conditions, which restrict performance. It will discuss the deficits of the bremsstrahlung technology and try to sketch future alternatives and their prospects of implementation in medical diagnostics.

    The Lithospheric structure of Eastern Anatolia and the surrounding region, including the northern part of the Arabian platform is investigated via the analysis and modeling of Bouguer anomalies from the Earth Gravitational Model EGM08. The effective elastic thickness of the lithosphere (EET) that corresponds to the mechanical cores of the crust and lithospheric mantle is determined from the spectral coherence between Bouguer anomalies and surface elevation data. Its average value is 18.7 km. From the logarithmic amplitude spectra of Bouguer anomalies, average depths of the lithosphere-asthenosphere boundary (LAB), Moho, Conrad and basement in the study area are constrained at 84 km, 39 km, 16 km and 7 km, respectively. The geometries of the LAB and Moho are then estimated using the Parker-Oldenburg inversion algorithm. We also present a lithospheric strength map obtained from the spatial variations of EET determined by Yield Stress Envelopes (YSE). The EET varies in the range of 12-23 km, which is in good agreement with the average value obtained from spectral analysis. Low EET values are interpreted as resulting from thermal and flexural lithospheric weakening. According to the lithospheric strength of the Eastern Anatolian region, the rheology model consists of a strong but brittle upper crust, a weak and ductile lower crust, and a weak lower part of the lithosphere. On the other hand, lithosphere strength corresponds to weak and ductile lower crust, a strong upper crust and a strong uppermost lithospheric mantle for the northern part of the Arabian platform.

  14. From plasma immersion ion implantation to deposition: A historical perspective on principles and trends

    2001-06-14

    Plasma immersion techniques of surface modification are known under a myriad of names. The family of techniques reaches from pure plasma ion implantation, to ion implantation and deposition hybrid modes, to modes that are essentially plasma film deposition with substrate bias. In the most general sense, all plasma immersion techniques have in common that the surface of a substrate (target) is exposed to plasma and that relatively high substrate bias is applied. The bias is usually pulsed. In this review, the roots of immersion techniques are explored, some going back to the 1800s, followed by a discussion of the groundbreaking works of Adler and Conrad in the 1980s. In the 1990s, plasma immersion techniques matured in theoretical understanding, scaling, and the range of applications. First commercial facilities are now operational. Various immersion concepts are compiled and explained in this review. While gas (often nitrogen) ion implantation dominated the early years, film-forming immersion techniques and semiconductor processing gained importance. In the 1980s and 1990s we have seen exponential growth of the field but signs of slowdown are clear since 1998. Nevertheless, plasma immersion techniques have found, and will continue to have, an important place among surface modification techniques.

    Three experiments addressed controversies in the previous literature on the development of phonological and other forms of short-term memory coding in children, using assessments of picture memory span that ruled out potentially confounding effects of verbal input and output. Picture materials were varied in terms of phonological similarity, visual similarity, semantic similarity, and word length. Older children (6/8-year-olds), but not younger children (4/5-year-olds), demonstrated robust and consistent phonological similarity and word length effects, indicating that they were using phonological coding strategies. This confirmed findings initially reported by Conrad (1971), but subsequently questioned by other authors. However, in contrast to some previous research, little evidence was found for a distinct visual coding stage at 4 years, casting doubt on assumptions that this is a developmental stage that consistently precedes phonological coding. There was some evidence for a dual visual and phonological coding stage prior to exclusive use of phonological coding at around 5-6 years. Evidence for semantic similarity effects was limited, suggesting that semantic coding is not a key method by which young children recall lists of pictures.

    The use of active personal dosemeters (APD) in interventional radiology was evaluated by Working Group 9 (Radiation protection dosimetry of medical staff) of the CONRAD project, which is a Coordination Action supported by the European Commission within its sixth Framework Programme. Interventional radiology procedures can be very complex and they can lead to relatively high doses to personnel who stand close to the primary radiation field and are mostly exposed to radiation scattered by the patient. For the adequate dosimetry of the scattered photons, APDs must be able to respond to low-energy [10-100 keV] and pulsed radiation with relatively high instantaneous dose rates. An intercomparison of five APD models deemed suitable for application in interventional radiology was organised in March 2007. The intercomparison used pulsed and continuous radiation beams, at CEA-LIST (Saclay (France)) and IRSN (Fontenay-aux-Roses (France)), respectively. A specific configuration, close to the clinical practice, was considered. The reference dose, in terms of Hp(10), was derived from air kerma measurements and from the measured and calculated energy distributions of the scattered radiation field. Additional Monte Carlo calculations were performed to investigate the energy spectra for different experimental conditions of the intercomparison. The results of this intercomparison are presented in this work and indicate which APDs are able to provide a correct response when used in the specific low-energy spectra and dose rates of pulsed X-rays encountered in interventional radiology.

    Full Text Available O filósofo da ciência Ian Hacking diz que nosso mundo é um mundo de classificações e que essas classificações têm efeitos particulares quando se referem a comportamentos de pessoas. Neste trabalho, pretende-se discutir como o diagnóstico do Transtorno de Déficit de Atenção com Hiperatividade (TDAH infantil pode funcionar como uma classificação e, assim, afetar o comportamento das crianças diagnosticadas. Inicialmente, é realizada uma discussão sobre a função das classificações na ciência. A partir dessas considerações, um modelo mais geral sobre a interação entre classificações e classificados é proposto, tendo como base a distinção de Ian Hacking entre tipos indiferentes e tipos interativos, e também a noção de efeito de arco proposta por esse autor. Por fim, o modelo é aplicado ao TDAH, onde são realizadas considerações relacionadas às noções de controle social de Peter Conrad.

    Full Text Available This article presents the main ideas and views of Edward W. Said on the relationship between culture and imperialism, and also on the link between Western culture and the formation of imperialism. Hence, special attention is given to Said’s interpretation of novels as constructions of the geopolitical reality: i.e. the characteristics of “imperialism” are examined as found in such English and French writers as Jane Austen, Rudyard Kipling, Joseph Conrad and Albert Camus, illustrating the way how novels as an aesthetic form participated in the “cultural construction” of colonialism. In the next part of the discussion, the paper presents another main topic of Edward Said that reveals how “cultural imperialism”, “orientalism” and “covering Islam” are still, unfortunately, current topics. Special attention is given to Said's demystification of the opposition between “us” and “them”, or “the West” and “Others”, through the example of the relationship between “the West” and “Islam”. Behind this issue, unequal power relations exist, as well as unequal relations of power and knowledge; “anti-systemic movements”, especially, and the “post-colonial discourse”, in general, warns us of this.

    Mobile technology ownership in the general US population and medical professionals is increasing, leading to increased use in clinical settings. However, data on use of mobile technology by psychiatry residents remain unclear. In this study, our aim was to provide data on how psychiatric residents use mobile phones in their clinical education as well as barriers relating to technology use. An anonymous, multisite survey was given to psychiatry residents in 2 regions in the United States, including New Orleans and Boston, to understand their technology use. All participants owned mobile phones, and 79% (54/68) used them to access patient information. The majority do not use mobile phones to implement pharmacotherapy (62%, 42/68) or psychotherapy plans (90%, 61/68). The top 3 barriers to using mobile technology in clinical care were privacy concerns (56%, 38/68), lack of clinical guidance (40%, 27/68), and lack of evidence (29%, 20/68). We conclude that developing a technology curriculum and engaging in research could address these barriers to using mobile phones in clinical practice. ©Shih Gipson, John Torous, Robert Boland, Erich Conrad.

    1994-01-01

    Syncrude Canada Ltd. is the world's largest producer of custom made crude oil from the oil sands, and the largest single source of oil in Canada. This annual report claimed many outstanding achievements for 1994. A new production record resulted in higher revenue, lower unit operating costs, increased cash flow, improved productivity, and higher net income. With a focus on technology development and continuous improvement in operations, including environment, health and safety performance, operating results are projected to improve further. The formation of the Canadian Oil Sands Network for Research and Development (CONRAD) early in 1994 was a major step assuring maximum leverage from every dollar expended to realize this objective. Production of Syncrude Sweet Blend is expected to rise by over 10 million barrels to 81 million barrels a year at an average cash operating expenditure of Can$12.00/ barrel by the year 2000.

    A bio-active polysaccharide, which was the major component of the extract of the common okra, Hibiscus esculentus, was isolated from the extract by precipitation with ethanol between 28.5 to 45%. According to a previous report (Whistler, R.L. and Conrad, H.E. (1954) J. Am. Chem. Soc. 76, 1673-1674), this polysaccharide contains the Gal alpha 1-->4Gal sequence, which is the ligand for the uropathogenic Escherichia coli and toxic lectins. Analysis of the binding property of the okra polysaccharide by precipitin assay with Gal, GalNAc and GlcNAc specific lectins showed that this okra mucilage reacted best with Mistletoe toxic lectin-I (ML-I) and precipitated over 80% of the ML-I nitrogen (5.1 micrograms N) added. It also precipitated well with Abrus precatorius (APA), Momordica charantia (MCA) and Ricinus communis (RCA1) agglutinins, but poorly with other lectins. The results obtained suggest that this polysaccharide is a valuable reagent to differentiate Gal specific lectins from the GalNAc and/or GlcNAc specific series.

    Today, quantitative analysis of three-dimensional (3D) dynamics of the left ventricle (LV) cannot be performed directly in the catheter lab using a current angiographic C-arm system, which is the workhorse imaging modality for cardiac interventions. Therefore, myocardial wall analysis is completely based on the 2D angiographic images or pre-interventional 3D/4D imaging. In this paper, we present a complete framework to study the ventricular wall motion in 4D (3D+t) directly in the catheter lab. From the acquired 2D projection images, a dynamic 3D surface model of the LV is generated, which is then used to detect ventricular dyssynchrony. Different quantitative features to evaluate LV dynamics known from other modalities (ultrasound, magnetic resonance imaging) are transferred to the C-arm CT data. We use the ejection fraction, the systolic dyssynchrony index a 3D fractional shortening and the phase to maximal contraction (ϕ i, max ) to determine an indicator of LV dyssynchrony and to discriminate regionally pathological from normal myocardium. The proposed analysis tool was evaluated on simulated phantom LV data with and without pathological wall dysfunctions. The LV data used is publicly available online at https://conrad.stanford.edu/data/heart. In addition, the presented framework was tested on eight clinical patient data sets. The first clinical results demonstrate promising performance of the proposed analysis tool and encourage the application of the presented framework to a larger study in clinical practice. (paper)

    Full Text Available Authors: Helen Schultz (Ed., Jeffrey Bagraim, Tracy Potgieter, Conrad Viedge, Amanda Werner Publisher: Van Schaik Publishers According to the authors the aim of this book is to present an interdisciplinary approach to the understanding of organisational behaviour within the contemporary South African environment. Within this framework, the book targets (senior undergraduate and postgraduate students in Industrial/Organisational Psychology and Human Resources Management. The text is written in a simple, conversational style (as was the intention of the authors that should be suitable for most undergraduate students at English-speaking tertiary institutions. The book is organised into three sections based on a model of four components of organizational behaviour: the individual, the group and the organisation. The fourth component of the model, the environment, refers specifically in the context of this book, to a contemporary South African approach to understanding behaviour in organisations. In the ‘individual’ section, the authors cover topics such as individual differences (e.g. personality, attitudes, perceptions, emotional intelligence, etc., ethics, work motivation, and performance management. In the ‘group’ section, the authors look at issues of group and team dynamics, power and empowerment, communication, decision-making and leadership. Finally, in the ‘organisation’ section, the authors address issues of contemporary organisational design, organisational change and employee well-being (e.g. stress management, job satisfaction, etc..

  5. Environmental issues in the oilsands : problems and solutions

    Lambert, G.

    1999-01-01

    The environmental challenges facing the oil sand industry in Alberta are discussed, including the cumulative effects to air, water quality, aquatic ecosystems, soils, vegetation, wildlife, human health and traditional land use. Each of these concerns are briefly reviewed, using Suncor's announced developments as the background. Although ground level excesses of SO 2 and NO x are not expected to be an issue, there are concerns about acidification. Soils and sensitive water bodies can potentially be affected by acid deposition as a result of SO 2 and NO x emissions. Historical ozone monitoring has shown that peak hourly ozone levels have not exceeded air quality guidelines in the last five years in either Fort McKay or Fort McMurray. The conclusion is that environmental impacts are manageable, but predictions based on environmental assessment should be monitored, and if necessary, corrective action be taken. The recent spate of multi-stakeholder collaborative projects such as the Regional Aquatic Monitoring Program (RAMP), the Canadian Oil Sands Network for Research and Development (CONRAD), and the Regional Air Quality Coordinating Committee (RAQCC) collectively do a very good job of ensuring responsible management of environmental and socio-economic issues. An environmental management system model structured with a regional board representing various stakeholders with a number of technical issue groups reporting to the Board has been proposed. The proposed model is now under assessment by the Cumulative Environmental Effects Management Initiative (CEEM), a group that includes aboriginal groups, federal, provincial, and municipal governments, environmental groups and regional resource industries

  6. The sexualization of the medical.

    2012-01-01

    The medicalization of sex is part of an already-in-place discursive problem that can be illuminated by looking at efforts to sexualize the medical. "Erectile dysfunction," "female sexual dysfunction," and their real and imagined pharmacopia, do not constitute the medicalization of sex; they are effects of sex already having been-to borrow a term from Peter Conrad ( 1992 )-healthicized. The equation of sex and health, as cultural common sense, has made health seem like the natural discourse for thinking about sex in the first place. Reversing the terms of this special issue, and using the methodology of rhetorical analysis, this article looks at the person with cancer as a sexualized subject-someone whose health is represented as intimately tied to his or her sex life. It suggests that, in public discourse-and notably in movies and on television-sex is the comic ending of the illness narrative. In light of this narrative move, the ability to have good sex joins the ability to be positive and cheerful as a (Western) cultural imperative of illness experience, in general, and cancer experience, in particular. Public representations of illness virtues often fail, then, to answer realistically the compelling question, "How shall I be ill?"

    Records of the past geomagnetic field can be divided into two main categories. These are instrumental historical observations on the one hand, and field estimates based on the magnetization acquired by rocks, sediments and archaeological artefacts on the other hand. In this paper, a new database combining historical, archaeomagnetic and volcanic records is presented. HISTMAG is a relational database, implemented in MySQL, and can be accessed via a web-based interface (http://www.conrad-observatory.at/zamg/index.php/data-en/histmag-database). It combines available global historical data compilations covering the last ∼500 yr as well as archaeomagnetic and volcanic data collections from the last 50 000 yr. Furthermore, new historical and archaeomagnetic records, mainly from central Europe, have been acquired. In total, 190 427 records are currently available in the HISTMAG database, whereby the majority is related to historical declination measurements (155 525). The original database structure was complemented by new fields, which allow for a detailed description of the different data types. A user-comment function provides the possibility for a scientific discussion about individual records. Therefore, HISTMAG database supports thorough reliability and uncertainty assessments of the widely different data sets, which are an essential basis for geomagnetic field reconstructions. A database analysis revealed systematic offset for declination records derived from compass roses on historical geographical maps through comparison with other historical records, while maps created for mining activities represent a reliable source.

  8. X-rays revolutionized the world

    1995-01-01

    This year marks the 100th anniversary of Professor Wilhelm Conrad Roentgen's accidental discovery of x-radiation. On 8 November 1895, Roentgen was conducting laboratory tests at the University of Wuertsburg in order to study cathode rays in a gasdischarge tube. He noticed that a fluorescence paper that happened to be near the tube began to glow even though the radiation should not have penetrated the shield of the gas-discharge tube. Less than two months later Roentgen reported the discovery of a new type of penetrating radiation, which he called x-rays. The discovery became an immediate worldwide sensation, and doctors realised that they could now see inside the human body without surgery. In Finland, the first x-ray equipment was acquired as early as 1900. The following year, Roentgen was awarded the Nobel prize in physics for his work. The health risks of x-radiation were noticed early on, but their severity was not always understood. The new x-ray examination methods were difficult to control and the exposure times then were quite long. It was therefore not uncommon that radiation damage eventually led to skin cancer and haematological diseases. (orig.) (7 figs.)

    Since its original discovery by Wilhelm Conrad Rontgen in 1895, one of the directions of researchers pursued was an application of x-ray radiography to larger objects, while the advent of high voltage x-ray tubes allowed radiographs of industrial objects to be produced in a reasonable amount of time. In spite of the great motivation we have to survey the earth's interior, we now know that x rays are not sufficiently penetrative to successfully target geophysical objects. Our current knowledge about the cross sections of the muon with matter solves the problem about this x-ray's inspectable size limit. These particles do not interact strongly with matter, and those with relativistic momentum travel long distances penetrating deep into rock. By tracking the ray paths of the muon after passing through the object, the method gives researchers the ability to study the earth in new ways. The purpose of this article is to review recent progress in probing the earth's interior with muons.

    Full Text Available El paisaje epigenético es una metáfora gráfica propuesta por Conrad H. Waddington para explicar el desarrollo de los organismos mediante la imagen de un paisaje compuesto por una superficie ondulante con cimas y valles, que representan las vías por las cuales se desplazan las células del organismo en su proceso de diferenciación. C.H. Waddington, considerado como el padre de la epigenética, es notable por sus aportes teóricos, que incluyen las nociones de asimilación genética, la canalización del desarrollo y el epi-genotipo. Estas ideas surgieron a partir de estudios experimentales en biología del desarrollo, los cuales resultaron en el descubrimiento del “organizador” en embriones de aves y, posteriormente, de fenocopias inducidas por factores ambientales en Drosophila. En el presente artículo se presenta una interpretación del paisaje epigenético y conceptos relacionados, que ponen en evidencia el poder heurístico de este modelo y su importancia para la biología contemporánea.

    Full Text Available Contraction forms in English are mostly occur in speech and informal writing and they are generally avoided in formal writing types such as academic prose, business reports and journal articles, therefore, most teachers discourage their use in academic essays (Biber, Johansonn, Leech, Conrad and Finegan 1999. Contractions in English have two types; negative contractions (isn’t, haven’t, doesn’t and verb contractions (I’m, they’ve, that’s. This corpus based study attempts to investigate contraction usage in learner and native English speaker essays. Major goal is to examine whether learners consider essay writing rules in respect of contractions which are accepted inappropriate for academic prose style. Five corpora, three learner and two native English, were utilized in order to analyze verb and not-contraction forms. Frequency calculations of contraction forms in each corpus compared via log-likelihood measurement for statistical significance.  Results revealed that learners use considerably more contraction forms, especially negative ones, than native English students in their argumentative essays.

  14. The origins of radiotherapy: discovery of biological effects of X-rays by Freund in 1897, Kienböck's crucial experiments in 1900, and still it is the dose.

    The discovery of X-rays by Wilhelm Conrad Röntgen (1845-1923) was triggered by pursuing an anomalous phenomenon: arousal of fluorescence at a distance from tubes in which cathode rays were elicited, a phenomenon which suggested the existence of a new kind of ray other than cathode rays. The discovery of biological effects of these X-rays by Leopold Freund (1868-1943) was triggered by pursuit of the purportedly useless phenomenon of epilation and dermatitis ensuing from X-ray-diagnostic experiments that others had reported. The crucial experiments performed by Robert Kienböck (1871-1953) entailed the proof that X-ray-dose, not electric phenomena, was the active agent of biological effects ensuing when illuminating the skin using Röntgen tubes. For both the discovery of X-rays and the discovery of their biological effectiveness, priority did not matter, but understanding the physical and medico-biological significance of phenomena that others had ignored as a nuisance. Present discussions about the clinical relevance of improving the dose distribution including protons and other charged particles resemble those around 1900 to a certain degree.

    1998-01-01

    Ways in which the onshore petroleum industry can meet the challenges of technological development in the new century to allow the industry to operate in a sustainable fashion were discussed. Advances in the areas of emissions control, environment protection, production, process automation and in situ heavy oil production have been mentioned as the most important guarantors of sustainable development. Ongoing work to combat emissions includes: (1) electricity from flare gas, (2) flare performance, (3) waste gas injection, (4) zero gas emissions equipment for wells, and (5) enhanced coalbed methane recovery. From the vantage point of improving environmental performance, efforts to minimize surface disturbance, to treat drilling wastes, and to remediate sites with native plants have shown good results. Technology developments in production include: (1) downhole gas/water separation and downhole oil/water separation, (2) water coning control, and (3) pipelines. The most significant advances in automation are the increased use of SCADA monitoring systems and pump off controllers. The two most notable developments in the in situ heavy oil exploitation area are the Steam Assisted Gravity Drainage (SAGD) process and its variant, the Vapex process. The most successful pilot to date has been the AOSTRA Underground Test Facility project in Athabasca. Cooperative research in numerical simulations, tomographic imaging, carbon dioxide, solvent and steam experiments and methane injection work have been cited as the most promising among the collaborative projects promoted by the Canadian Oilsands Network for Research and Development (CONRAD)

    Cyanobacteria are well established model organisms for the study of oxygenic photosynthesis, nitrogen metabolism, toxin biosynthesis, and salt acclimation. However, in comparison to other model bacteria little is known about regulatory networks, which allow cyanobacteria to acclimate to changing environmental conditions. The current work has begun to illuminate how transcription factors modulate expression of different photosynthetic regulons. During the past few years, the research on other regulatory principles like RNA-based regulation showed the importance of non-protein regulators for bacterial lifestyle. Investigations on modulation of photosynthetic components should elucidate the contributions of all factors within the context of a larger regulatory network. Here, we focus on regulation of photosynthetic processes including transcriptional and posttranscriptional mechanisms, citing examples from a limited number of cyanobacterial species. Though, the general idea holds true for most species, important differences exist between various organisms, illustrating diversity of acclimation strategies in the very heterogeneous cyanobacterial clade.

    We investigate the ability of the short baseline neutrino (SBN) experimental program at Fermilab to test the globally-allowed (3 +N ) sterile neutrino oscillation parameter space. We explicitly consider the globally-allowed parameter space for the (3 +1 ), (3 +2 ), and (3 +3 ) sterile neutrino oscillation scenarios. We find that SBN can probe with 5 σ sensitivity more than 85%, 95% and 55% of the parameter space currently allowed at 99% confidence level for the (3 +1 ), (3 +2 ) and (3 +3 ) scenarios, respectively, with the (3 +N ) allowed space used in these studies closely resembling that of previous studies [J. M. Conrad, C. M. Ignarra, G. Karagiorgi, M. H. Shaevitz, and J. Spitz, Adv. High Energy Phys. 2013, 1 (2013)., 10.1155/2013/163897], calculated using the same methodology. In the case of the (3 +2 ) and (3 +3 ) scenarios, C P -violating phases appear in the oscillation probability terms, leading to observable differences in the appearance probabilities of neutrinos and antineutrinos. We explore SBN's sensitivity to those phases for the (3 +2 ) scenario through the currently planned neutrino beam running, and investigate potential improvements through additional antineutrino beam running. We show that, if antineutrino exposure is considered, for maximal values of the (3 +2 ) C P -violating phase ϕ54, SBN could be the first experiment to directly observe ˜2 σ hints of C P violation associated with an extended lepton sector.

    The work presented here aims to improve models used in the fission cross section evaluation. The results give insights for a significant breakthrough in this field and yielded large extensions of the evaluation code CONRAD. Partial cross sections are inherently strongly correlated together as of the competition of the related reactions must yield the total cross section. Therefore improving fission cross section benefits to all partial cross sections. A sound framework for the simulation of competitive reactions had to be settled in order to further investigate on the fission reaction; this was implemented using the TALYS reference code as guideline. After ensuring consistency and consistency of the framework, focus was made on fission. Perspective resulting from the use of macroscopic-microscopic models such as the FRDM and FRLDM were analyzed; these models have been implemented and validated on experimental data and benchmarks. To comply with evaluation requirements in terms of computation time, several specific numerical methods have been used and parts of the program were written to run on GPU. These macroscopic-microscopic models yield potential energy surfaces that can be used to extract a one-dimensional fission barrier. This latter can then be used to obtained fission transmission coefficients that can be used in a Hauser-Feshbach model. This method has been finally tested for the calculation of the average fission cross section for 239 Pu(n,f). (author) [fr

    In the framework of the 2006 experimental benchmark organized at the GSI (Darmstadt, Germany) by the EC CONRAD network, a neutron dosimetry intercomparison was performed in a workplace field around a carbon target hit by 400 MeV/u 12 C ions. The radiation protection group of the INFN-LNF participated to the intercomparison with a Bonner sphere spectrometer equipped with an active 6 LiI(Eu) scintillator and a set of passive detectors, namely MCP-6s (80mgcm -2 )/MCP-7 TLD pairs from TLD Poland. Both active and passive spectrometers, independently tested and calibrated, were used to determine the field and dosimetric quantities in the measurement point. The FRUIT unfolding code, developed at the INFN-LNF radiation protection group, was used to unfold the raw BSS data. This paper compares the results of the active or passive spectrometers, obtaining a satisfactory agreement in terms of both spectrum shape and value of the integral quantities, as the neutron fluence or the ambient dose equivalent. These results allow qualifying the BSS based on TLD pairs as a reliable passive method to be used around high energy particle accelerators even in low dose rate areas. This is particularly useful in those workplaces where the active instruments could be disturbed by the presence of pulsed fields, large photon fluence or electromagnetic noise

    It is not particularly remarkable that this topic was one that I chose for an IAEA Symposium which I presented in 1974. My thesis in 1974 was that the basic recommendations and regulations on dose limitation were unchanged from the early 1920s to the date of that lecture. What is remarkable is that during the middle to late 1970s the basis for such recommendations changed to a scientific approach based on risk, and as a result, the recommendations have been under change and modification ever since, although perhaps, as we will see, we may be at a point of some stability once again. I will return to the historical developments, particularly relevant during this Congress when we are celebrating the discovery of the X-ray by William Conrad Roentgen just 100 years ago this past November, and the discovery of radioactivity by Becquerel 100 years ago last month. You should also understand that much of this presentation will focus primarily on activities of both the National Council of Radiation Protection and Measurements (NCRP), with particular emphasis on the International Commission on Radiological Protection (ICRP).

    Full Text Available Genome-wide scans of genetic variation can potentially provide detailed information on how modern humans colonized the world but require new methods of analysis. We introduce a statistical approach that uses Single Nucleotide Polymorphism (SNP data to identify sharing of chromosomal segments between populations and uses the pattern of sharing to reconstruct a detailed colonization scenario. We apply our model to the SNP data for the 53 populations of the Human Genome Diversity Project described in Conrad et al. (Nature Genetics 38,1251-60, 2006. Our results are consistent with the consensus view of a single "Out-of-Africa" bottleneck and serial dilution of diversity during global colonization, including a prominent East Asian bottleneck. They also suggest novel details including: (1 the most northerly East Asian population in the sample (Yakut has received a significant genetic contribution from the ancestors of the most northerly European one (Orcadian. (2 Native North [corrected] Americans have received ancestry from a source closely related to modern North-East Asians (Mongolians and Oroquen that is distinct from the sources for native South [corrected] Americans, implying multiple waves of migration into the Americas.

    Water flow imaging may help to better understand various problems related to water stress of plants. It may help to fully understand the water relations of plants. The objective of this research was to estimate the velocity of water flow in plant samples. Cut roses ( Rosa hybrida, var. 'Milva') were used as samples. Cold neutron radiography (CNR) was conducted at CONRAD, Helmholtz Center Berlin for Materials and Energy, Berlin, Germany. D 2O and H 2O were interchangeably injected into the water feeding system of the sample. After the uptake of D 2O, the neutron transmission increased due to the smaller attenuation coefficient of D 2O compared to H 2O. Replacement of D 2O in the rose peduncle was clearly observed. Three different optical flow algorithms, Block Matching, Horn-Schunck and Lucas-Kanade, were used to calculate the vector of D 2O tracer flow. The quality of sequential images providing sufficient spatial and temporal resolution allowed to estimate flow vector.

    Two issues have been examined that are important to heavy ion beam cavity design: vaporization and condensation of wall material and active pumping of noncondensable cavity gases. These issues have been studied in the context of a particular target chamber design where the first wall is covered with flowing liquid lithium. A computer code, CONRAD, has been written to simulate the vaporization and condensation. Scaling laws have been devised from basic laws of physics and results of computer simulations for the case of liquid lithium protected cavities. These scaling laws can be used to calculate the allowable repetition rate for the cavity based on the dimensions and conditions of the cavity and the allowed gas density. Standard gas pumping formulas are used to estimate the pumping power needed to clear the cavity of noncondensable gases. The area of cryopanels has been determined for a given design of the tube through which the pumping occurs. The contamination of the cryopanels by lithium vapor has been studied and is found to be a potentially serious problem

    MT measurement of transects was made in the central part of North-Eastern Japan Arc to clarify tectonics of subduction zones. 1-D, 2-D and 3-D resistivity structures are observed in surface layers, and zones shallower and deeper than a Conrad surface, respectively. A main structure direction is S-N or NNE-SSW. Ishinomaki-Chokai tectonic line and low- resistivity zones due to Quaternary volcanos (Naruko, Onikobe) exist in a backbone range region. Resistivity is 100{Omega}{center_dot}m or less by Bostick Inversion except Mesozoic and Palaeozoic layers in the southern Kitakami mountainous region, resulting in a good agreement with previous results in a north transect. Resistivity is several {Omega}{center_dot}m and depth is several km around Shinjo basin and in surface layers of Kitakami River region. The backbone range region shows complex resistivity structures because of volcanic activity and wide-area hot water activity. High-resistivity layers correspond to stable Mesozoic and Palaeozoic land layers. Seismic velocity increases in the low-resistivity zone. Earthquake generally occurs at the boundary between resistivity structures. 68 refs., 9 figs., 2 tabs.

    Some activities of EURADOS Working Group 9 (WG9) are presently funded by the European Commission (CONRAD project). The objective of WG9 is to promote and co-ordinate research activities for the assessment of occupational exposures to staff at workplaces in interventional radiology (IR) and nuclear medicine. For some of these applications, the skin of the fingers is the limiting organ for individual monitoring of external radiation. Therefore, sub-group 1 of WG9 deals with the use of extremity dosemeters in medical radiation fields. The wide variety of radiation field characteristics present in a medical environment together with the difficulties in measuring a local dose that is representative for the maximum skin dose, usually with one single detector, makes it difficult to perform accurate extremity dosimetry. Sub-group 1 worked out a thorough literature review on extremity dosimetry issues in diagnostic and therapeutic nuclear medicine and positron emission tomography, interventional radiology and interventional cardiology and brachytherapy. Some studies showed that the annual dose limits could be exceeded if the required protection measures are not taken, especially in nuclear medicine. The continuous progress in new applications and techniques requires an important effort in radiation protection and training. (authors)

  7. Ordered groups and infinite permutation groups

    CERN Document Server

    1996-01-01

    The subjects of ordered groups and of infinite permutation groups have long en­ joyed a symbiotic relationship. Although the two subjects come from very different sources, they have in certain ways come together, and each has derived considerable benefit from the other. My own personal contact with this interaction began in 1961. I had done Ph. D. work on sequence convergence in totally ordered groups under the direction of Paul Conrad. In the process, I had encountered "pseudo-convergent" sequences in an ordered group G, which are like Cauchy sequences, except that the differences be­ tween terms of large index approach not 0 but a convex subgroup G of G. If G is normal, then such sequences are conveniently described as Cauchy sequences in the quotient ordered group GIG. If G is not normal, of course GIG has no group structure, though it is still a totally ordered set. The best that can be said is that the elements of G permute GIG in an order-preserving fashion. In independent investigations around that t...

Based on historical records, the (German for spread through Europe after 1495 and shared symptoms with what we know today as syphilis. Many cities took measures to protect their population. Here, transliterations of archival documents from the 15 and 16 century (provided in the appendix are used to trace the steps taken by the governing authorities in Zurich to deal with this emerging infectious disease. One of the central measures taken by the city was to establish a quarantine facility referred to as the The city doctors, including the well-known physician and naturalist Conrad Gessner, oversaw the obligatory quarantine and treatment of patients with symptoms. Treatment could range from better nutrition, herbal remedies and skin ointments to aggressive heat therapy and “smoking”. Furthermore, the affliction was suspected as a sexually acquired disease, hence prostitutes and infected foreigners were extradited from the city. Meanwhile, the church used its social influence to promote a more “Christian” behavior. In several respects, the public health measures taken in the 16 century against a new and menacing epidemic do not diverge in their basic rationale from approaches used during the 20 century and today.

    We have determined the complete sequence of the mitochondrial genome of the scaphopod mollusk Graptacme eborea (Conrad, 1846) (14,492 nts) and completed the sequence of the mitochondrial genome of the bivalve mollusk Mytilus edulis Linnaeus, 1758 (16,740 nts). (The name Graptacme eborea is a revision of the species formerly known as Dentalium eboreum.) G. eborea mtDNA contains the 37 genes that are typically found and has the genes divided about evenly between the two strands, but M. edulis contains an extra trnM and is missing atp8, and has all genes on the same strand. Each has a highly rearranged gene order relative to each other and to all other studied mtDNAs. G. eborea mtDNA has almost no strand skew, but the coding strand of M. edulis mtDNA is very rich in G and T. This is reflected in differential codon usage patterns and even in amino acid compositions. G. eborea mtDNA has fewer non-coding nucleotides than any other mtDNA studied to date, with the largest non-coding region being only 24 nt long. Phylogenetic analysis using 2,420 aligned amino acid positions of concatenated proteins weakly supports an association of the scaphopod with gastropods to the exclusion of Bivalvia, Cephalopoda, and Polyplacophora, but is generally unable to convincingly resolve the relationships among major groups of the Lophotrochozoa, in contrast to the good resolution seen for several other major metazoan groups.

    Unionid bivalves or freshwater pearly-mussels (Unionoidea: Unionidae) serve as an exemplary system for examining many of the problems facing systematists and conservation biologists today. Most of the species and genera were described in the late 1800s and early 1900s, but few phylogenetic studies have been conducted to test conventional views of species and classification. Pearly-mussels of Gulf Coastal drainages of the southeastern United States from the Escambia (southern Alabama to Florida) to the Suwannee Rivers (Florida) are a unique fauna comprised of approximately 100 species, with about 30 endemic to the region. In this study, mitochondrial cytochrome c oxidase subunit I and 16S rRNA gene sequences were used to test the monophyly and to estimate evolutionary relationships of five unionid species representing three different genera. The molecular phylogenies depict all three genera as polyphyletic. The prodigious polyphyly exhibited within unionids is due to incorrect notions of homology and false assumptions about missing anatomical data. In contrast, the molecular phylogeny provides evidence to support the recognition of all five unionid species as distinct evolutionary entities. Furthermore, molecular genealogical evidence supports the elevation of Quincuncina infucata (Conrad) of the Suwannee River to species level, for which Q. kleiniana (Lea) is available.

  11. A Covariance Generation Methodology for Fission Product Yields

    2016-01-01

    Full Text Available Recent safety and economical concerns for modern nuclear reactor applications have fed an outstanding interest in basic nuclear data evaluation improvement and completion. It has been immediately clear that the accuracy of our predictive simulation models was strongly affected by our knowledge on input data. Therefore strong efforts have been made to improve nuclear data and to generate complete and reliable uncertainty information able to yield proper uncertainty propagation on integral reactor parameters. Since in modern nuclear data banks (such as JEFF-3.1.1 and ENDF/BVII.1 no correlations for fission yields are given, in the present work we propose a covariance generation methodology for fission product yields. The main goal is to reproduce the existing European library and to add covariance information to allow proper uncertainty propagation in depletion and decay heat calculations. To do so, we adopted the Generalized Least Square Method (GLSM implemented in CONRAD (COde for Nuclear Reaction Analysis and Data assimilation, developed at CEA-Cadarache. Theoretical values employed in the Bayesian parameter adjustment are delivered thanks to a convolution of different models, representing several quantities in fission yield calculations: the Brosa fission modes for pre-neutron mass distribution, a simplified Gaussian model for prompt neutron emission probability, theWahl systematics for charge distribution and the Madland-England model for the isomeric ratio. Some results will be presented for the thermal fission of U-235, Pu-239 and Pu-241.

    This study focused on integrating rheology and colloid science to improve recovery of bitumen in surface mined oil sands. Factors that influence recovery, such as conditions of particle interaction, solids concentration and shear rate, were reviewed. In an effort to understand the rheological behaviour of clay-in-water suspensions, an elaborate procedure was developed to separate an inter-bedded clay layer from a site at Albian Sands Energy Inc. The variables were water chemistry, solids concentration, and shear rate. The research study was conducted at the Alberta Research Council with the support of the CONRAD Extraction Group. A controlled stress rheometer was used to provide the quantitative evaluations of the clay slurry properties. The research results indicate that the viscoelastic properties of the slurry are highly influenced by the shear history of the slurry, solids content, calcium concentration, and sample aging. Shear thinning behaviour was observed in all slurry samples, but the slurry viscosity increased with test time for a given shear rate. In order to classify the slurries, a method was developed to distinguish the gel strength. The slurries were then classified into 3 distinct patterns, including no gel, weak gel and strong gel. The evolution of the experimental protocols were described along with the current stability maps that correlate the domains of the gel strength according to the solids concentration, calcium ion content, and shear rate. It was concluded that the rheological properties of oil sands slurries influence bitumen recovery in commercial surface-mined oil sands operations. tabs., figs.

    Full Text Available Statistic analyses demonstrate that the probability of earthquake occurrence in many earthquake regions strongly depends on the time of day, that is on Local Time (e.g. Conrad, 1909, 1932; Shimshoni, 1971; Duma, 1997; Duma and Vilardo, 1998. This also applies to strong earthquake activity. Moreover, recent observations reveal an involvement of the regular diurnal variations of the Earth’s magnetic field, commonly known as Sq-variations, in this geodynamic process of changing earthquake activity with the time of day (Duma, 1996, 1999. In the article it is attempted to quantify the forces which result from the interaction between the induced Sq-variation currents in the Earth’s lithosphere and the regional Earth’s magnetic field, in order to assess the influence on the tectonic stress field and on seismic activity. A reliable model is obtained, which indicates a high energy involved in this process. The effect of Sq-induction is compared with the results of the large scale electromagnetic experiment "Khibiny" (Velikhov, 1989, where a giant artificial current loop was activated in the Barents Sea.

The encapsulation was performed using Apo’s ability to disassemble reversibly into its subunits at low pH (2.7 and reassemble in neutral pH (7.2, physically entrapping drug molecules in its cavity (creating ApoDox. In this study, ApoDox was prepared in water and phosphate-buffered saline and stored for 12 weeks in various conditions (-20°C, 4°C, 20°C, and 37°C in dark, and 4°C and 20°C under ambient light. During storage, a very low amount of prematurely released drug molecules were detected (maximum of 7.5% for ApoDox prepared in PBS and 4.4% for ApoDox prepared in water. Fourier-transform infrared spectra revealed no significant differences in any of the samples after storage. Most of the ApoDox prepared in phosphate-buffered saline and ApoDox prepared in water and stored at -20°C formed very large aggregates (up to 487% of original size. Only ApoDox prepared in water and stored at 4°C showed no significant increase in size or shape.

    OttomanState will be analyzed based on the data from foreign policy statistics. Osmanlı Devleti’nin son on yılı birbirini takip eden savaşlarla geçmiştir. Bu son on yıl bir Türk-İtalyan savaşı olan Trablusgarp Savaşı ile başlar, Balkan Savaşları, Dünya Savaşı ve Milli Mücadele hareketi ile sona ermiştir. Bu savaşlar devletin hem siyasi itibarını hem de ekonomik durumunu derinden sarsmış ve sonunda Osmanlı Devleti’nin tarihteki yerini almasıyla sonuçlanmıştır.Trablusgarp ve Balkan Savaşları, meydana geldikleri süreç içerisinde Osmanlı Devleti’nin hem harici siyasetini hem de iktisadini hayatını derinden etkilemiştir. İtalya’nın 1911 yılında Trablusgarp topraklarını işgal etmesi ile başlayan Türk-İtalyan Savaşı, Osmanlı-İtalyan ticari ilişkileri üzerinde kısa bir süre de olsa gerginliğin oluşmasına neden olmuştur. Daha önce, 1908’de, Avusturya-Macaristan’ın Bosna-Hersek’i işgali üzerine Avusturya mallarına yapılan boykot örneği 1911 yılında İtalyan mallarına da uygulanmaya başlamıştır. Boykot fikri, ilk olarak Hükümetin İtalya’ya savaş ilan etme konusunda gecikmesi nedeniyle basında ortaya çıkmıştır. Ancak Babıâli, kapitülasyonlar nedeniyle İtalyan mallarının ülkeye girişini önleyemediği için ilk önlem olarak İtalyan mallarından alınan gümrük vergilerini yükseltme yoluna gitmiştir. Bu uygulamaya 1912’deki barış antlaşmasına kadar devam edilmiştir.1912 yılında Osmanlı Devleti, liderliğini Bulgaristan’ın yaptığı Balkan devletlerinin aralarında oluşturdukları ittifakla (Bulgaristan-Sırbistan-Yunanistan-Karadağ bir oldu-bitti karşısında kendisini savaşın içinde bulmuştur.

    . Increased moisture content is associated with increased deposition velocities at a given steady-state concentration: for every 5 % increase in soil moisture content, the ratio of deposition velocity to steady state concentration increases by 5.13±1.3 x 10-7cm2/s/ppb. Based on these observations, we conclude that uptake rate of H2 and CO in soil increases with increase in soil moisture content over the range characteristic of unsaturated soils, in contrast to the previous observation that increasing soil moisture level from 30% to 60% caused a large drop in hydrogen uptake rate (Yonemura et al., 1999)-a situation encountered during flood or heavy down pour. Our results indicate that the H2 consuming activity of soil is rapidly activated upon wetting and reaches a maximum at about 15% moisture level. This deduction supports the results obtained by several workers (Conrad and Seiler, 1980 ; Moxley and Smith, 1997) who showed that there is an optimum moisture level for microbiological hydrogen and CO uptake in soil.

  20. Ion implantation planar in targets with semi-cylindrical grooves

    2002-01-01

    The experimental and numerical investigations suggest that the ion-matrix phase of the sheath evolution plays a crucial role in determining the ion flux to the target surfaces . It can easily be realized that conformal mapping of the target's surface by the sheath is questionable, or even inapplicable in the case of surfaces with fine irregularities or this continuities. The theoretical analysis of such cases is evidently quite complicated. On the other hand, most actual targets fall into this category, and hence, the understanding of the corresponding sheath behavior remains vital for accomplishing uniform implantation. The ion- matrix sheaths have been treated analytically by Conrad for planar, cylindrical and spherical targets successfully. Similar y, Sheridan and Zang et al. have investigated the ion matrix sheath in cylindrical bores, without and with axial electrodes, respectively. All these works assumed targets with infinite areas or length, Zeng et al. and Kwok et al. have started studying implantation into grooves, by carrying out simulations for the inner and outer races of bearings, which are modeled as semi- cylinders of infinite length. Finally, Demokan has presented the first analytic treatment of on matrix sheaths in two- dimensions, by considering targets with rectangular grooves of infinite length, representing a broad range of industrial items. In this work, ion-matrix sheath near infinite length are theoretically analysed. Understanding the sheath formation near such targets is essential for achieving successful ion implantation on the surfaces of a broad range of industrial products, including all types of bearings. The potential profiles both inside and outside the groove are derived and the consequent ion velocity higher plasma densities may improve the uniformity of implantation on the surfaces of such grooves. Furthermore, the sheath edge deformation due to the grooves, the variation of the angle of incidence on the surface of the groove

The concept Waddington explained, the epigenetic landscape, was not based on settled science, and its implications were not easy to grasp. Unlike proponents of the most successful contemporary biological theory, Waddington was committed to including all biological phenomena–no matter how complex or unusual–in a single theoretical system. His intellectual style and use of images matched his ambition. Waddington used compelling images to get his readers to engage with and work through his theories. His images used a shifting, even contradictory, set of metaphors and analogical models, from train yards to crafted topological surfaces. Through an analysis of Waddington’s images and theories, I show that taking a close look at what scientific images show and how they show it is important for the historiography of science. Images can be effective at drawing viewers in, confounding them, and prodding them to ask questions; this is one reason images are necessary for science.

    Radiation have been influencing the living and non living systems on earth, since their evolution from simple, humble beginnings to diversely complex system of the present day biological world. Most of the radiations have been the basis for conduction and completion of vital life processes like photosynthesis which form the base and initiation point of flow of energy within the biological world. However there are some radiation called as ionizing radiation with energy content of more then 124 eV, which have the capacity to cause deleterious effects in livings system ranging from simple unicellular organisms to the large and complex animals and plants. The discovery of X-ray by William Conrad Roentgen in 1898 provided the originating point for radiation biology as a well defined discipline. Together with the discovery of X-ray radioactivity and new radioactive elements the biological effects of ionizing radiation began to be studied immediately after the discovery of X-ray. By the year 1896 press reports regarding the skin injuries involved skin erythemas and ulceration in persons who experienced the frequent and prolonged action of X-ray had appeared. By 1959, 359 radiologists were known to have died of X-ray induced cancer of skin or of leukemia. The deleterious effects of radiation on a large scale became evident when a large number of deaths, approximately 10,300 had occurred when USA dropped atom bomb on the Japanese towns of Hiroshima and Nagasaki, leaving about 80,000 persons injured. The effects of these two explosions are still evident in generation of today and also these twin incidents evoked awareness among the researchers to investigate the nature and effects of radiation which they cause in living beings.

    Full Text Available Background: The recently developed Context Assessment for Community Health (COACH tool aims to measure aspects of the local healthcare context perceived to influence knowledge translation in low- and middle-income countries. The tool measures eight dimensions (organizational resources , community engagement, monitoring services for action, sources of knowledge, commitment to work, work culture, leadership, and informal payment through 49 items. Objective: The study aimed to explore the understanding and stability of the COACH tool among health providers in Vietnam. Designs: To investigate the response process, think-aloud interviews were undertaken with five community health workers, six nurses and midwives, and five physicians. Identified problems were classified according to Conrad and Blair's taxonomy and grouped according to an estimation of the magnitude of the problem's effect on the response data. Further, the stability of the tool was examined using a test–retest survey among 77 respondents. The reliability was analyzed for items (intraclass correlation coefficient (ICC and percent agreement and dimensions (ICC and Bland–Altman plots. Results: In general, the think-aloud interviews revealed that the COACH tool was perceived as clear, well organized, and easy to answer. Most items were understood as intended. However, seven prominent problems in the items were identified and the content of three dimensions was perceived to be of a sensitive nature. In the test–retest survey, two-thirds of the items and seven of eight dimensions were found to have an ICC agreement ranging from moderate to substantial (0.5–0.7, demonstrating that the instrument has an acceptable level of stability. Conclusions: This study provides evidence that the Vietnamese translation of the COACH tool is generally perceived to be clear and easy to understand and has acceptable stability. There is, however, a need to rephrase and add generic examples to clarify

  6. «Quotation and Literary Echo as Structural Principles in Gabriele Wohmann's Frühherbst in Badenweiler.»

    1980-09-01

    Full Text Available In her novel of 1978, Wohmann uses the montage technique—quotations, literary echoes, erudite allusions—of the «classics of modernism» to put the contemporary West German phenomenon of «New Inwardness» in an ironic light. Her protagonist, the composer Hubert Frey, retreats from the stresses of contemporary life to the Black Forest spa of Badenweiler. New Inwardness in him appears allied to New Conservatism which, in reaction to the New Left of the sixties, revives the old German ideal of the «A-Political Man.» Echoing a work of restaurative mentality, Stifter's Nachsommer , Frey's Frühherbst looks back nostalgically on Goethe's classicist phase. As Goethe put his Storm and Stress behind him, Frey analogously repudiates the turbulent youth of the sixties. He sums up his ethos of withdrawal by quoting a passage from one of Goethe's letters. He quotes inaccurately and his self-identification with Goethe rests on shaky foundations. By revealing her protagonist's erudition as faulty and confused, Wohmann unmasks his whole stance as—literally—false. Another of Frey's models, Conrad Aiken, a writer of inwardness and subjectivity, turns out to have been the wrong author for Frey's choice of Badenweiler. The American writer who had actually sojourned there turns out to have been the realist Stephen Crane. Inwardness thus proves literally incorrect and inappropriate to the protagonist's needs. The displacement of the symbolist Aiken by the realist Crane points ahead to the conclusion of the novel. Whereas a World War had been needed to dislodge Thomas Mann's Hans Castorp from his retreat, a mere mouse, invading Frey's hotel room, serves the analogous function in Wohmann's novel. Literary echo, a structural device, functions thematically as both the symptom and the cure of her protagonist's passing relapse into German inwardness.

    The Institute for Nuclear Safety and Protection (IPSN), the technical support of the French nuclear safety authority, provides the technical support needed for protect the surrounding population from the consequences of radioactive releases. In the event of an accident arising at a nuclear facility, the IPSN would set up an Emergency Response Technical Centre (CTC) at Fontenay-aux-Roses. The IPSN's objectives are: (a) to diagnose the state of the nuclear facility and monitor its development, (b) to prepare prognosis for the evolution of the accident and to give an estimation of the associated consequences according to the situation evolution, (c) to estimate the risk of radioactive releases and the consequences on man and on the environment, mainly on the basis of weather forecasts and on the prognosis. This diagnosis-prognosis approach is build-up with the information on the state of the installation given by: the concerned site via audio-conference system and telescope, the security panels of the nuclear plant via networks. To perform its missions, the CTC, which has to be both safe and secure, uses multiple telecommunication resources to dialogue with partners and also mapping computer systems, data bases and software tools: (a) the SESAME system, which gives, during an accident of a PWR, a calculation method for the diagnosis-prognosis aforesaid, (b) the CONRAD system, which calculates the atmospheric dispersal of radioactive substances and consequences in the environment in the early phase of an accident, (c) the ASTRAL code, which allows to cope with long lasting situations. In order to be operational, the IPSN expert regularly undergo training in emergency situation management and participate in exercises organised by the government authorities. (author)

  8. Rationale and Safety Assessment of a Novel Intravaginal Drug-Delivery System with Sustained DL-Lactic Acid Release, Intended for Long-Term Protection of the Vaginal Microbiome.

    Bacterial vaginosis is a prevalent state of dysbiosis of the vaginal microbiota with wide-ranging impact on human reproductive health. Based on recent insights in community ecology of the vaginal microbiome, we hypothesize that sustained vaginal DL-lactic acid enrichment will enhance the recruitment of lactobacilli, while counteracting bacterial vaginosis-associated bacteria. We therefore aimed to develop an intravaginal device that would be easy to insert and remove, while providing sustained DL-lactic acid release into the vaginal lumen. The final prototype selected is a vaginal ring matrix system consisting of a mixture of ethylene vinyl acetate and methacrylic acid-methyl methacrylate copolymer loaded with 150 mg DL-lactic acid with an L/D-lactic acid ratio of 1:1. Preclinical safety assessment was performed by use of the Slug Mucosal Irritation test, a non-vertebrate assay to evaluate vaginal mucosal irritation, which revealed no irritation. Clinical safety was evaluated in a phase I trial with six healthy nulliparous premenopausal volunteering women, with the investigational drug left in place for 7 days. Colposcopic monitoring according to the WHO/CONRAD guidelines for the evaluation of vaginal products, revealed no visible cervicovaginal mucosal changes. No adverse events related to the investigational product occurred. Total release from the intravaginal ring over 7 days was estimated through high performance liquid chromatography at 37.1 (standard deviation 0.9) mg DL-lactic acid. Semisolid lactic acid formulations have been studied to a limited extent in the past and typically consist of a large volume of excipients and very high doses of lactic acid, which is of major concern to mucosal safety. We have documented the feasability of enriching the vaginal environment with pure DL-lactic acid with a prototype intravaginal ring. Though the efficacy of this platform remains to be established possibly requiring further development, this approach may offer a

    Accurate taxonomic placement is vital to conservation efforts considering many intrinsic biological characteristics of understudied species are inferred from closely related taxa. The rayed creekshell, Anodontoides radiatus (Conrad, 1834), exists in the Gulf of Mexico drainages from western Florida to Louisiana and has been petitioned for listing under the Endangered Species Act. We set out to resolve the evolutionary history of A. radiatus, primarily generic placement and species boundaries, using phylogenetic, morphometric, and geographic information. Our molecular matrix contained 3 loci: cytochrome c oxidase subunit I, NADH dehydrogenase subunit I, and the nuclear-encoded ribosomal internal transcribed spacer I. We employed maximum likelihood and Bayesian inference to estimate a phylogeny and test the monophyly of Anodontoides and Strophitus. We implemented two coalescent-based species delimitation models to test seven species models and evaluate species boundaries within A. radiatus. Concomitant to molecular data, we also employed linear morphometrics and geographic information to further evaluate species boundaries. Molecular and morphological evidence supports the inclusion of A. radiatus in the genus Strophitus, and we resurrect the binomial Strophitus radiatus to reflect their shared common ancestry. We also found strong support for polyphyly in Strophitus and advocate the resurrection of the genus Pseudodontoideus to represent ‘Strophitus’ connasaugaensis and ‘Strophitus’ subvexus. Strophitus radiatus exists in six well-supported clades that were distinguished as evolutionary independent lineages using Bayesian inference, maximum likelihood, and coalescent-based species delimitation models. Our integrative approach found evidence for as many as 4 evolutionary divergent clades within S. radiatus. Therefore, we formally describe two new species from the S. radiatus species complex (Strophitus williamsi and Strophitus pascagoulaensis) and recognize

    The problem of Jan Evangelista Purkinje's succession will be presented according to the results of archival research. The Ministery of Cult and Education in Vienna, and especially Karl Rokitansky, who was the adviser for medical education, in 1867 created a new professorship and Institute for Physiology, beside Purkinje and his Institute. Maximilian Vintschgau was to assist the world-famous 80 years old Purkinje but was not permitted to teach the whole field of physiology and to examine students. The fact that the professors of the Prague Medical Faculty in 1868 started to remove the restrictions for Vintschgau with the argument of academic freedom and in 1869 tried to keep the second institute for the future, is not yet mentioned in the literature. Discussions about the problems of the Czech language and its use in physiological lectures were scarcely mentioned by the Ministery: if one day there should be a Czech-speaking lecturer, the problem would be solved. Unfortunately Purkinje had no genuine pupil in Prague, and after his death, Vintschgau was provisional director of the Institute for half a year. In this situation Rokitansky decided that there should only be one institute for physiology in Prague. The Medical Faculty wanted to have Hermann Helmholtz to succeed Purkinje, but Helmholtz refused to come. Ewald Hering, who was nominated in the second place by the Faculty, accepted the call. Vintschgau had only rank four, third was Conrad Eckhard from Giessen. The Ministery in Vienna, however, made a special decision: The Medical Faculty of Innsbruck was founded in 1869, and there was not professor for physiology at the beginning of 1870. The candidates of the Insbruck Medical Faculty were neglected in favour of Vintschgau, who was considered to be a trustworthy Austrian patriot. Hering and Vintschgau became professors on March 6, 1870, and Hering started his work in Prague in a new institute in the "Wenzelsbad".

  12. Can Harry Potter still put a spell on us in a second language? An fMRI study on reading emotion-laden literature in late bilinguals.

    In this fMRI study we contrasted emotional responses to literary reading in late bilinguals' first or second language. German participants with adequate English proficiency in their second language (L2) English read short text passages from Harry Potter books characterized by a "negative" or "positive" versus "neutral" emotional valence manipulation. Previous studies have suggested that given sufficient L2 proficiency, neural substrates involved in L1 versus L2 do not differ (Fabbro, 2001). On the other hand, the question of attenuated emotionality of L2 language processing is still an open debate (see Conrad, Recio, & Jacobs, 2011). Our results revealed a set of neural structures involved in the processing of emotion-laden literature, including emotion-related amygdala and a set of lateral prefrontal, anterior temporal, and temporo-parietal regions associated with discourse comprehension, high-level semantic integration, and Theory-of-Mind processing. Yet, consistent with post-scan emotion ratings of text passages, factorial fMRI analyses revealed stronger hemodynamic responses to "happy" than to "neutral" in bilateral amygdala and the left precentral cortex that were restricted to L1 reading. Furthermore, multivariate pattern analyses (MVPA) demonstrated better classifiability of differential patterns of brain activity elicited by passages of different emotional content in L1 than in L2 for the whole brain level. Overall, our results suggest that reading emotion-laden texts in our native language provides a stronger and more differentiated emotional experience than reading in a second language.

Previous work established the unexpected result that a mean annual climate warming of c. 0.6 °C since the 1940's has not led to upward movement of the forest limit. Here we explore the relative importance of summer and winter climatic conditions on growth and age-class structure of the treeline forming species, Dracophyllum longifolium and Dracophyllum scoparium over the second half of the 20th century. The relationship between climate and growth and establishment were evaluated using standard dendroecological methods and local climate data from a meteorological station on the island. Growth and establishment were correlated against climate variables and further evaluated within hierarchical regression models to take into account the effect of plot level variables. Winter climatic conditions exerted a greater effect on growth and establishment than summer climatic conditions. Establishment is maximized under warm (mean winter temperatures >7 °C, dry winters (total winter precipitation <400 mm. Growth, on the other hand, is adversely affected by wide winter temperature ranges and increased rainfall. The contrasting effect of winter warmth on growth and establishment suggests that winter temperature affects growth and establishment through differing mechanisms. We propose that milder winters enhance survival of seedlings and, therefore, recruitment, but increases metabolic stress on established plants, resulting in lower growth rates. Future winter warming may therefore have complex effects on plant growth and establishment globally.

    The purpose of this study was to replicate and extend research on the meanings for sex and commitment using a sample of first semester college students (N = 268). We examined responses to a series of open-ended questions about participants' meanings for sex and how they described these meanings as connected with relationship commitment. Our qualitative analyses replicated those of Olmstead, Billen, Conrad, Pasley, and Fincham (2013). Our largest group was the Committers (sex is indicative of love and trust and occurs after commitment is developed in a relationship), followed by Flexibles (sex can hold deep personal meaning, but can also be purely for pleasure and isn't always connected with commitment), and then Recreationers (sex is a basic need or purely for pleasure and is not associated with commitment). Groups were then examined based on demographic characteristics and pre-college hookup experience. Groups were found to differ by gender, relationship status and type, religiosity, and pre-college hookup experience. For example, a greater proportion of women than men were in the Committers group, whereas a greater proportion of men than women were in the Flexibles and Recreationers groups. Those in the Committers group had fewer pre-college hookup partners than Flexibles and Recreationers; however, Flexibles and Recreationers did not differ in number of pre-college hookup partners. We then followed up (at the end of the semester) with a subsample (n = 73) of participants to examine whether meanings for sex and commitment remained stable or changed over a brief period of time. The majority (82.2 %) of participants' meanings remained stable. For those whose meanings shifted, meanings became more consistent with those of the Committers group than the other two groups. Implications for research and sexual and relationship education are discussed.

  16. The Rebirth of the Musical Author in Recent Fiction Written in English

    2012-05-01

    Full Text Available In his 2005 monograph on The Author, Andrew Bennett reflects on how “authorship is central to the way in which critical practice is currently conceptualized and theorized”. The rebirth of the author in contemporary criticism is being accompanied by a renewed fascination with the figure of the author as the subject of recent fiction. This can be seen reflected in current portrayals of real and fictional writers such as Henry James, in David Lodge’s Author, Author (2004, or Olive Wellwood, in A.S. Byatt’s The Children’s Book (2009. Moreover, the recovery of the author can be traced as well in the context of the emergence of music as a fertile referent for interartistic narratives. In terms of the dialogue between contemporary fiction and music, there seems to be a common interest in the image of the author, both in the act of creation, as a composer, and of re-creation, as a performer. Works such as Bernard MacLaverty’s Grace Notes (1997, Vikram Seth’s An Equal Music (1999, Conrad Williams’ The Concert Pianist (2006, or Kazuo Ishiguro’s Nocturnes. Five Stories of Music and Nightfall (2009 favour the author-musician’s perspective as they interact with music in different ways. In light of this, the aim of this article is to explore the process of rebirth of the musical author in recent fiction written in English, analysing this trend as part of a more general tendency to recover the author’s presence and voice in both fiction and criticism.

  17. Anisotropic characterization of magnetorheological materials

    For the development of energy efficient lightweight parts novel function integrating materials are needed. Concerning this field of application magnetorheological (MR) fluids, MR elastomers and MR composites are promising materials allowing the adjustment of mechanical properties by an external magnetic field. A key issue for operating such structures in praxis is the magneto-mechanical description. Most rheological properties are gathered at laboratory conditions for high magnetic flux densities and a single field direction, which does not correspond to real praxis conditions. Although anisotropic formation of superstructures can be observed in MR suspensions (Fig. 1) or experimenters intentionally polymerize MR elastomers with anisotropic superstructures these MR materials are usually described in an external magnetic field as uniform, isotropic materials. This is due to missing possibilities for experimentally measuring field angle dependent properties and ways of distinguishing between material properties and frictional effects. Just a few scientific works experimentally investigated the influence of different field angles (Ambacher et al., 1992; Grants et al., 1990; Kuzhir et al., 2003) or the influence of surface roughness on the shear behaviour of magnetic fluids (Tang and Conrad, 1996) . The aim of this work is the introduction of a novel field angle cell allowing the determination of anisotropic mechanical properties for various MR materials depending on the applied magnetic field angle. - Highlights: • Novel magnetic field angle testing device (MFATD) presented. • Determination of magnetic field dependent anisotropic mechanical properties. • Experimental data for different field directions shown for a commercial MR fluid. • Material description of MR fluids as transversal-isotropic solids. • Magnetic field angle dependent variations in shear stresses experimentally measured. • Determination of frictional coefficients between the MR fluid and

  18. Crustal Stretching Style and Lower Crust Flow of the South China Sea Northern Margin

    Bai, Y.; Dong, D.; Runlin, D.

    2017-12-01

    There is a controversy about crustal stretching style of the South China Sea (SCS) northern margin mainly due to considerable uncertainty of stretching factor estimation, for example, as much as 40% of upper crust extension (Walsh et al., 1991) would be lost by seismic profiles due to poor resolution. To discover and understand crustal stretching style and lower crustal flow on the whole, we map the Moho and Conrad geometries based on gravity inversion constrained by deep seismic profiles, then according to the assumption of upper and lower crust initial thickness, upper and lower crust stretching factors are estimated. According to the comparison between upper and lower crust stretching factors, the SCS northern margin could be segmented into three parts, (1) sediment basins where upper crust is stretched more than lower crust, (2) COT regions where lower crust is stretched more than upper crust, (3) other regions where the two layers have similar stretching factors. Stretching factor map shows that lower crust flow happened in both of COT and sediment basin regions where upper crust decouples with lower crust due to high temperature. Pressure contrast by sediment loading in basins and erosion in sediment-source regions will lead to lower crust flow away from sediment sink to source. Decoupled and fractured upper crust is stretched further by sediment loading and the following compensation would result in relatively thick lower crust than upper crust. In COT regions with thin sediment coverage, low-viscosity lower crust is easier to thin in extensional environment, also the lower crust tends to flow away induced by magma upwelling. Therefore, continental crust on the margin is not stretching in a constant way but varies with the tectonic setting changes.

    The patient experience has moved to the forefront of health care-delivery research. The University of Texas MD Anderson Cancer Center Department of Diagnostic Radiology began collaborating in 2011 with the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management, and in 2013 with the University of Nevada, Las Vegas, William F. Harrah College of Hotel Administration, to explore the application of service science to improving the patient experience. A collaborative pilot study was undertaken by these 3 institutions to identify and rank the specific needs and expectations of patients undergoing imaging procedures in the MD Anderson Department of Diagnostic Radiology. We first conducted interviews with patients, providers, and staff to identify factors perceived to affect the patient experience. Next, to confirm these factors and determine their relative importance, we surveyed more than 6,000 patients by e-mail. All factors considered important in the interviews were confirmed as important in the surveys. The surveys showed that the most important factors were acknowledgment of the patient's concerns, being treated with respect, and being treated like a person, not a "number"; these factors were more important than privacy, short waiting times, being able to meet with a radiologist, and being approached by a staff member versus having one's name called out in the waiting room. Our work shows that it is possible to identify and rank factors affecting patient satisfaction using techniques employed by the hospitality industry. Such factors can be used to measure and improve the patient experience. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    models for the Cretaceous seafloor-spreading history of East Gondwana result in unlikely tectonic scenarios for at least one of the plate boundaries involved and/or violate particular constraints from at least one of the associated ocean basins. We link East Gondwana spreading corridors by integrating magnetic and gravity anomaly data from the Enderby Basin off East Antarctica within a regional plate kinematic framework to identify a conjugate series of east-west-trending magnetic anomalies, M4 to M0 ( 126.7-120.4 Ma). The mid-ocean ridge that separated Greater India from Australia-Antarctica propagated from north to south, starting at 136 Ma northwest of Australia, and reached the southern tip of India at 126 Ma. Seafloor spreading in the Enderby Basin was abandoned at 115 Ma, when a ridge jump transferred the Elan Bank and South Kerguelen Plateau to the Antarctic plate. Our revised plate kinematic model helps resolve the problem of successive two-way strike-slip motion between Madagascar and India seen in many previously published reconstructions and also suggests that seafloor spreading between them progressed from south to north from 94 to 84 Ma. This timing is essential for tectonic flow lines to match the curved fracture zones of the Wharton and Enderby basins, as Greater India gradually began to unzip from Madagascar from 100 Ma. In our model, the 85-East Ridge and Kerguelen Fracture Zone formed as conjugate flanks of a "leaky" transform fault following the 100 Ma spreading reorganization. Our model also identifies the Afanasy Nikitin Seamounts as products of the Conrad Rise hotspot.

Some research offers support for the ability of systematic, supported, longitudinal contact between different groups of individuals to improve attitudes. College campuses, in particular, offer a potentially useful arena in which to facilitate this type of contact. This study explored contextual factors (eg, geographic region, biological sex and predictors of disability-related attitudes among a college student population to determine strategies for course-based intervention design (eg, as community-engaged or service-learning initiatives. Surveying participants from universities in two regions of the United States, we found that self-esteem, audience-based communication apprehension, and contact with PwD explain more than 50% of the variance in disability-related attitudes. Further, we found that geographic location affects both self-esteem and audience-based communication apprehension (communicating/interacting with PwD. We discuss the implications for community engagement and/or service learning and highlight the importance of partnerships among relevant community stakeholders, including university faculty, students, and staff.

    Campbell Island, an isolated island 600 km south of New Zealand mainland (52 °S, 169 °E) is oceanic (Conrad Index of Continentality  =  -5) with small differences between mean summer and winter temperatures. Previous work established the unexpected result that a mean annual climate warming of c. 0.6 °C since the 1940's has not led to upward movement of the forest limit. Here we explore the relative importance of summer and winter climatic conditions on growth and age-class structure of the treeline forming species, Dracophyllum longifolium and Dracophyllum scoparium over the second half of the 20th century. The relationship between climate and growth and establishment were evaluated using standard dendroecological methods and local climate data from a meteorological station on the island. Growth and establishment were correlated against climate variables and further evaluated within hierarchical regression models to take into account the effect of plot level variables. Winter climatic conditions exerted a greater effect on growth and establishment than summer climatic conditions. Establishment is maximized under warm (mean winter temperatures >7 °C), dry winters (total winter precipitation <400 mm). Growth, on the other hand, is adversely affected by wide winter temperature ranges and increased rainfall. The contrasting effect of winter warmth on growth and establishment suggests that winter temperature affects growth and establishment through differing mechanisms. We propose that milder winters enhance survival of seedlings and, therefore, recruitment, but increases metabolic stress on established plants, resulting in lower growth rates. Future winter warming may therefore have complex effects on plant growth and establishment globally.

    1997-05-01

    Near the village of Villarino de los Aires, in the province of Salamanca, Spain, was an existing underground hydroelectric power plant. A major enlargement was undertaken to increase the electrical generating capacity, under a contract awarded to a joint venture of Dragados y Construcciones, S. A. (Spain), Entrecanales y Tavora, S. A. (Spain), and S.A. Conrad Zschokke (Switzerland). The enlargement required the excavation of a large and complex underground system of tunnels, shafts and chambers adjacent to existing facilities and interconnected with these facilities. The existing machine hall and transformer chamber were both extended, requiring the blasting of the existing end walls. The drilling, blasting and excavating of the underground system had to be done without damage to existing underground chambers and tunnels, or any of the existing structures, equipment or instrumentation facilities, often within just a few feet of the blasting. This required careful control of vibrations, airblast overpressures and dust. Because the only available non-electric detonating systems were found to be unreliable and unsafe, electric systems would be preferred if they could be used in a safe manner at this site. High electrical potentials existed at the site, and the facilities could not be shut down. Electrical fields were studied carefully, both in the underground environment and above the ground surface. Based on these results, it was concluded that electric detonators could be used if special blasting procedures were developed and followed. In accord with contracting practices of this Spanish agency, the contract was not awarded to the lowest bidder, but to the bidder who demonstrated the best understanding of the project and who presented the best technical proposal for conducting the work to a conclusion that would be satisfactory to the owner. The development of the technical proposal was a two-month effort for a technical group and support staff, prepared in Madrid.

    In subduction zones, non-volcanic tremors are associated with fluid circulations (Obara, 2002). Their sources are often located on the interplate boundary (Rogers and Dragert, 2003; Shelly et al, 2006; La Rocca, 2009), consistent with fluids released by the dehydration of subducted plates (Hacker et al., 2003). Reports of tremors in the overriding continental crust of several subduction zones in the world (Kao et al., 2005; Payero et al., 2008; Ide, 2012) suggest fluid circulation at shallower depths but potential fluid paths are poorly documented. Here we obtained seismic observations from receiver functions that evidence the close association between the shallow tremor zone, electrical conductivity, and tectonic features of the Cascadia overriding plate. A seismic discontinuity near 15 km depth in the crust of the overriding North American plate is attributed to the Conrad discontinuity. This interface is segmented, and its interruption is spatially correlated with conductive regions and shallow swarms of seismicity and non-volcanic tremors. These observations suggest that shallow fluid circulation, tremors and seismicity are controlled by fault zones limiting blocks of accreted terranes in the overriding plate (Brudzinski and Allen, 2007). These zones constitute fluid "escape" routes that may contribute unloading fluid pressure on the megathrust. Obara, K. (2002). Science, 296, 1679-1681. Rogers, G., & Dragert, H. (2003).

  9. The adenoid: Its history and a cautionary tale.

    Ruben, Robert J

    2017-06-01

    The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid. Removal of the adenoid became rapidly accepted worldwide as a treatment for many morbidities, including otitis, speech problems, cognitive problems, and sleep apnea. Until the 1920s, adenoidectomy often was performed as a staged procedure and without general anesthesia. Early tools and techniques included use of the bare fingernail, a finger ring knife, a curette, and electrical desiccation. From the mid-1930s to the early 1960s, radiation therapy of the adenoid was in extensive use, both for children and in caring for army aviators and navy submarine crews during WWII. The effectiveness of surgical adenoidectomy for hearing loss led to a belief that radiation, which had been found to ablate lymphoid tissue, would be equally effective, and led to the wide-spread use of radiation. Ultimately, 500 thousand to 2.5 million children and adults were estimated to have been treated with radiation, and follow-up studies found increased risk for cancer. Furthermore, a follow-up study by Stacey R. Guild (1890-1966), published in 1950, on a very large sample of children who previously were reported to have had their hearing loss diminished through radiation, found that irradiation had produced no effect on high-tone loss. Thus, irradiation was both useless and harmful. Acceptance of authority, which can lurk within medical culture, led to the development of a tragically misguided management of adenoid disease.

    We apply multiscale methods to describe the strained growth of multiple layers of C60 on a thin film of pentacene. We study this growth in the presence of a monolayer pentacene step to compare our simulations to recent experimental studies by Breuer and Witte of submonolayer growth in the presence of monolayer steps. The molecular-level details of this organic semiconductor interface have ramifications on the macroscale structural and electronic behavior of this system and allow us to describe several unexplained experimental observations for this system. The growth of a C60 thin film on a pentacene surface is complicated by the differing crystal habits of the two component species, leading to heteroepitactical growth. In order to probe this growth, we use three computational methods that offer different approaches to coarse-graining the system and differing degrees of computational efficiency. We present a new, efficient reaction-diffusion continuum model for 2D systems whose results compare well with mesoscale kinetic Monte Carlo (KMC) results for submonolayer growth. KMC extends our ability to simulate multiple layers but requires a library of predefined rates for event transitions. Coarse-grained molecular dynamics (CGMD) circumvents KMC's need for predefined lattices, allowing defects and grain boundaries to provide a more realistic thin film morphology. For multilayer growth, in this particularly suitable candidate for coarse-graining, CGMD is a preferable approach to KMC. Combining the results from these three methods, we show that the lattice strain induced by heteroepitactical growth promotes 3D growth and the creation of defects in the first monolayer. The CGMD results are consistent with experimental results on the same system by Conrad et al. and by Breuer and Witte in which C60 aggregates change from a 2D structure at low temperature to 3D clusters along the pentacene step edges at higher temperatures.

    This paper examined the concept of dynamic neural network (NN) modeling for short-term forecasts of coastal high-frequency (HF) radar current maps offshore of Galveston Texas. HF radar technology is emerging as a viable and affordable way to measure surface currents in real time and the number of users applying the technology is increasing. A 25 megahertz, two site, Seasonde HF radar system was used to map ocean and bay surface currents along the coast of Texas where wind and river discharge create complex and rapidly changing current patters that override the weaker tidal flow component. The HF radar system is particularly useful in this type of setting because its mobility makes it a good marine spill response tool that could provide hourly current maps. This capability helps improve deployment of response resources. In addition, the NN model recently developed by the Conrad Blucher Institute can be used to forecast water levels during storm events. Forecasted currents are based on time series of current vectors from HF radar plus wind speed, wind direction, and water levels, as well as tidal forecasts. The dynamic NN model was tested to evaluate its performance and the results were compared with a baseline model which assumes the currents do not change from the time of the forecast up to the forecasted time. The NN model showed improvements over the baseline model for forecasting time equal or greater than 3 hours, but the difference was relatively small. The test demonstrated the ability of the dynamic NN model to link meteorological forcing functions with HF radar current maps. Development of the dynamic NN modeling is still ongoing. 18 refs., 1 tab., 5 figs

    Cyrtodactylus marmoratus Gray, 1831, a species of bent-toed gecko exhibiting a precloacal groove in males, was described on the basis of specimens collected by Heinrich Kuhl and Johan Conrad van Hasselt in Java, Greater Sunda Islands, Indonesia. Kluge (1985) subsequently designated a lectotype for C. marmoratus from a series of these specimens (i.e., syntypes), now housed in the herpetological collection at Naturalis (formerly the Rijksmuseum van Natuurlijke Historie; RMNH), Leiden, the Netherlands. Our work at Naturalis shows that the type series of C. marmoratus at RMNH actually comprises two sets of specimens, and that examination of specimens from one set or the other by different authors, including Kluge (1985), is responsible for some confusion surrounding the type series of this species. As a consequence, we present relevant morphological data for all 14 specimens constituting the type series of C. marmoratus at RMNH for the first time. The type status of two specimens of C. marmoratus in the collection at the Muséum National d'Histoire Naturelle, Paris, France, remains unresolved at present. Owing to the inconsistent naming and application of terms for some key characters (e.g., groove, sulcus, pit, hollow, depression) used in the diagnoses of Cyrtodactylus species, we here propose a set of novel and useful definitions that are supported by photographs. We also illustrate the sexually dimorphic expression of this character in C. marmoratus. Finally, we present a revised comparative table for the bent-toad geckos of the Sunda Islands and Sulawesi.

    The recently developed Context Assessment for Community Health (COACH) tool aims to measure aspects of the local healthcare context perceived to influence knowledge translation in low- and middle-income countries. The tool measures eight dimensions (organizational resources, community engagement, monitoring services for action, sources of knowledge, commitment to work, work culture, leadership, and informal payment) through 49 items. The study aimed to explore the understanding and stability of the COACH tool among health providers in Vietnam. To investigate the response process, think-aloud interviews were undertaken with five community health workers, six nurses and midwives, and five physicians. Identified problems were classified according to Conrad and Blair's taxonomy and grouped according to an estimation of the magnitude of the problem's effect on the response data. Further, the stability of the tool was examined using a test-retest survey among 77 respondents. The reliability was analyzed for items (intraclass correlation coefficient (ICC) and percent agreement) and dimensions (ICC and Bland-Altman plots). In general, the think-aloud interviews revealed that the COACH tool was perceived as clear, well organized, and easy to answer. Most items were understood as intended. However, seven prominent problems in the items were identified and the content of three dimensions was perceived to be of a sensitive nature. In the test-retest survey, two-thirds of the items and seven of eight dimensions were found to have an ICC agreement ranging from moderate to substantial (0.5-0.7), demonstrating that the instrument has an acceptable level of stability. This study provides evidence that the Vietnamese translation of the COACH tool is generally perceived to be clear and easy to understand and has acceptable stability. There is, however, a need to rephrase and add generic examples to clarify some items and to further review items with low ICC.

    Conrad Observatory is situated far away from roads and industrial areas on the Trafelberg in Lower Austria. At the end of the seismic tunnel, the main seismic instrument of the Observatory with a station code CONA is located. This station is one of the most important seismic stations in the Austrian Seismic Network (network code OE). The seismic observatory consists of a 145m long gallery and an underground laboratory building with several working areas. About 25 meters away from the station CONA, six temporary seismic stations were implemented for research purposes. Two of them were installed with the same equipment as CONA, while the remaining four stations were set up with digitizers having lower noise and higher resolution (Q330HR) and sensors with the same type (STS-2). In order to prevent possible disturbances by air pressure and temperature fluctuation, three walls were built inside of the tunnel. The first wall is located ca 63 meters from the tunnel entrance, while a set of double walls with a distance of 1.5 meters is placed about 53 meters from the first isolation wall but between the station CONA and the six temporary stations. To assess impact of the isolation walls on noise reduction and detection performance, investigations are conducted in two steps. The first study is carried out by comparing the noise level and detection performance between the station CONA behind the double walls and the stations in front of the double walls for verifying the noise isolation by the double walls. To evaluate the effect of the single wall, station noise level and detection performance were studied by comparing the results before and after the installation of the wall. Results and discussions will be presented. Additional experiment is conducted by filling insulation material inside of the aluminium boxes of the sensors (above and around the sensors). This should help us to determine an optimal insulation of the sensors with respect to pressure and temperature

    Full text: Currently, quantification of doses from high-energy radiation fields is a topical issue. This is so because high-energy neutrons play an important role for radiation exposure of air crew members and personnel outside the shielding of ion therapy facilities. In an effort to study air crew exposure from cosmic radiation in detail, two Bonner Sphere Spectrometers (BSSs) have recently been installed to measure secondary neutrons from cosmic radiation, one at the environmental research station 'Schneefernerhaus' at an altitude of 2650 m on the Zugspitze mountain, Germany, the other at the Koldewey station close to the North Pole on Spitsbergen. Based on the measured neutron fluence distributions and on fluence-to-dose conversion coefficients, mean ambient dose equivalent rate values of 75.0 ± 2.9 nSv/h and 8.7 ± 0.6 nSv/h were obtained for October 2008, respectively. Neutrons with energies above about 20 MeV contribute about 50% to dose, at 2650 m. Ambient dose equivalent rates measured by means of a standard rem counter and an extended rem counter at the Schneefernerhaus confirm this result. In order to study the response of state-of-the-art radiation instrumentation in such a high-energy radiation field, a benchmark exercise that included both measurements in and simulation of the stray neutron radiation field at the high-energy particle accelerator at GSI, Germany, were performed. This CONRAD (COordinated Network for RAdiation Dosimetry) project was funded by the European Commission, and the organizational framework was provided by the European Radiation Dosimetry Group, EURADOS. The Monte Carlo simulations of the radiation field and the experimental determination of the neutron spectra with various Bonner Sphere Spectrometers suggest the neutron fluence distributions to be very similar to those of secondary neutrons from cosmic radiation. The results of this intercomparison exercise in terms of ambient dose equivalent are also discussed

    Full text: Should an important release of radionuclides occur in the environment, one would quickly have to assess radionuclide concentration in media and foodstuff, deduce the potential exposition of concerned populations to the radiations, predict the evolution of the situation and propose different scenarios of managing the contaminated zones. To achieve this, the ASTRAL code was created, which can be used by a relatively large group of people composing crisis centers or making predictive impact studies. The starting point of the assessments is the ground deposit of radionuclides: the atmospheric dispersion phase and the cloud exposure are not taken into account here. The calculations achieved concern time evolution of radionuclide concentration in elements of the agricultural and forest food chain as well as assessment of doses due to external and internal exposure. These values are compared to regulation limits and/or intervention levels. Different simulations of contaminated zones management can be led by applying counter-measures, dispositions meant to reduce the accident's impact an environment and populations. The seventy radionuclides taken into account in the present version are some of those met in case of accidents or during the exploitation of a Pressurized Water Reactor (PWR). They relates to 37 elements that are : Ag, Am, Ba, Br, Cd, Ce, Cl, Cm, Co, Cr, Cs, Eu, Fe, I, Ir, La, Mn, Mo, Nb, Nd, Ni, Np, Pm, Pr, Rb, Rh, Ru, Sb, Sm, Sn, Sr, Tc, Te, Y, Zn, Zr. On a temporal point of view, the predictions extend to 3 years after the deposition. The starting point of calculations, deposits on the ground, can be issued from field measurements or predicted by a code - especially in an early phase when deposits are expected but have not occurred. Such predictions are performed by CONRAD, the atmospheric dispersion tool developed by IRSN for its Crisis Technical Center. A link in ASTRAL has been developed to fetch CONRAD's results and Input them in its database

    In order to investigate the structure of the crust beneath the Middle Qinling Mountains (MQL) and neighboring areas in the North China Block and South China Block, a north-south gravity profile from Yuquan in the Sichuan Basin to Yulin in the Ordos Basin was conducted in 2011. The Bouguer gravity anomaly is determined from a high-quality gravity dataset collected between 31°N and 36°N of latitude, and varies between -200 and -110 mGal in the study region. Using accredited velocity density relationships, an initial crust-mantle density model is constructed for MQL and adjacent areas, which is later refined interactively to simulate the observed gravity anomaly. The present study reveals the features of the density and Bouguer gravity with respect to the tectonic units sampled by the profile. The lithosphere density model shows typical density values that depict a layered structure and allow differentiate the blocks that extend along the reference profile. The gravity field calculated by forward modeling from the final density distribution model correlates well with the measured gravity field within a standard deviation of 1.26 mGal. The density in the crystalline crust increases with depth from 2.65 g/cm3 up to the highest value of 2.95 g/cm3 near the bottom of the crust. The Conrad interface is identified as a density jump of about 0.05 g/cm3. The average density of the crust in MQL is clearly lower than the density in the formations on both sides. Starting from a combined Airy-Pratt isostatic compensation model, a partly compensated crust is found below MQL, suggesting future growth of the crust, unlike the Ordos and Sichuan basins that will remain stable. On the basis of the density and isostatic state of the crust and additional seismological research, such as the P-wave velocity model and Poisson's ratio, it is concluded that the lower crust delamination is a reasonable interpretation for the geophysical characteristics below the Qinling Orogen.

    It is to Wilhelm Conrad Röntgen, the first elected "radiologist" of our Academy and the first Nobel Prize winner in physics, that we owe the transparency of the hand. We celebrate today the centenary of the great scientific discovery which was to revolutionize the diagnosis, and thereby the treatment, of a large number of illnesses the discovery of X-rays. It would be unjust not to link the name of this scientist with that of his wife, Bertha, who, ignorant of the dangers of all "novel medical inventions" volunteered her own hand for his research experiments: the hand which was to bring to the world tangible proof of this remarkable discovery. To a lesser degree, but nonetheless essential, we acknowledge, albeit not in exhaustive detail, all the progress made by the work of pioneers using this new investigative technique. So let us now return to the hand:--a body part which it was easy to immobilize, remembering that in those days a single radiographic exposure took up to an hour to obtain,--we will consider the immortalised hand of Bertha Röntgen,---to whom this address is dedicated,---and its radiographic exposures which allow us to appreciate the advances and to perceive the limitations of this technique. They also enable us better to envisage future investigative approaches whereby a deeper knowledge of the human body may be acquired. We note that compared with the histopathological sciences, imaging is not specific. Numerous microscopic structures, in particular neurological and vascular ones, are still insufficiently well visualised and the transmission pathways between the hand and the central nervous system deserve better characterisation. Current, research programmes are attempting to overcome these limitation of modern imaging. All the experience gained in studying the transparency of the hand, as we have discussed, is applicable to every part of the human anatomy. To credit: Röntgen's discovery with all its originality, we could say that the hand was

    Although the standard model of particle physics has been very successfull in describing nature it needs to be extended by the Higgs mechanism to explain the particle masses observed in experiments. This mechanism introduces a new elementary particle called the Higgs boson. Current research at particle accelerators focuses on the search for the Higgs boson as a major goal. This analysis uses the data recorded with the D0-detector of the Tevatron at the Fermi National Accelerator Laboratory (FNAL). The Tevatron collides protons and antiprotons at a center of mass energy of √(s)=1.96 TeV. The primary goal of the analysis was the search for a light Higgs boson in the WH channel. For this the process p anti p→WH→eνb anti b was used. Furthermore a measurement of the Wb anti b production cross section has been performed. For the measurements a total integrated luminosity of L=255 pb -1 was available. For the selection of the desired processes events with electrons, missing transverse momentum and at least two jets have been used. At least two of the jets were required to be identified as b-jets. To obtain an efficient event selection many event properties had to be calculated and methods to cut on them needed to be optimized. Based on the selected events the Wb anti b production cross section has been calculated. After including the branching ratio BR(W→eν)=0.108 the result is σ(Wb anti b)=21.8 pb +15.5 -20.0 pb(sys+stat) for events where the b-quarks satisfy p T >8 GeV und η 95 (Wb anti b)=60.9 pb has been obtained. The same basic event selection has been used to obtain an upper limit for the WH production cross section. For the statistical analysis of these events the method of Cousins and Feldman was used. This method was extended to include background uncertainties as proposed by Conrad et al. Finally for a standard model Higgs boson of 115 GeV mass an upper limit for the production cross section of σ 95 (WH)=12.2 pb has been obtained at a confidence

    Full Text Available Several computer programs are available for detecting copy number variants (CNVs using genome-wide SNP arrays. We evaluated the performance of four CNV detection software suites--Birdsuite, Partek, HelixTree, and PennCNV-Affy--in the identification of both rare and common CNVs. Each program's performance was assessed in two ways. The first was its recovery rate, i.e., its ability to call 893 CNVs previously identified in eight HapMap samples by paired-end sequencing of whole-genome fosmid clones, and 51,440 CNVs identified by array Comparative Genome Hybridization (aCGH followed by validation procedures, in 90 HapMap CEU samples. The second evaluation was program performance calling rare and common CNVs in the Bipolar Genome Study (BiGS data set (1001 bipolar cases and 1033 controls, all of European ancestry as measured by the Affymetrix SNP 6.0 array. Accuracy in calling rare CNVs was assessed by positive predictive value, based on the proportion of rare CNVs validated by quantitative real-time PCR (qPCR, while accuracy in calling common CNVs was assessed by false positive/false negative rates based on qPCR validation results from a subset of common CNVs. Birdsuite recovered the highest percentages of known HapMap CNVs containing >20 markers in two reference CNV datasets. The recovery rate increased with decreased CNV frequency. In the tested rare CNV data, Birdsuite and Partek had higher positive predictive values than the other software suites. In a test of three common CNVs in the BiGS dataset, Birdsuite's call was 98.8% consistent with qPCR quantification in one CNV region, but the other two regions showed an unacceptable degree of accuracy. We found relatively poor consistency between the two "gold standards," the sequence data of Kidd et al., and aCGH data of Conrad et al. Algorithms for calling CNVs especially common ones need substantial improvement, and a "gold standard" for detection of CNVs remains to be established.

    Exploration for potable water in developing countries continues to be a major activity, as there are more than one billion people without access to safe drinking water. Exploration for groundwater becomes more critical in regions where groundwater movement and occurrence is controlled by secondary features such as fractures and faults. Drilling success rates in such geological settings are generally very low, but can be improved by integrating geological, hydrogeological, aerial photo interpretation with land-based geophysical technology in the selection of drilling sites. To help alleviate water supply problems in West Africa, the Conrad N. Hilton Foundation and other donors, since 1990, have funded the World Vision Ghana Rural Water Project (GRWP) to drill wells for potable water supplies in the Greater Afram Plains (GAP) of Ghana. During the first two years of the program, drilling success rates using traditional methods ranged from 35 to 80 percent, depending on the area. The average drilling success rate for the program was approximately 50 percent. In an effort to increase the efficiency of drilling operations, the Desert Research Institute evaluated and developed techniques for application to well-siting strategies in the GAP area of Ghana. A critical project element was developing technical capabilities of in-country staff to independently implement the new strategies. Simple cost-benefit relationships were then used to evaluate the economic advantages of developing water resources using advanced siting methods. The application of advanced methods in the GAP area reveal an increase of 10 to 15 percent in the success rate over traditional methods. Aerial photography has been found to be the most useful of the imagery products covering the GAP area. An effective approach to geophysical exploration for groundwater has been the combined use of EM and resistivity methods. Economic analyses showed that the use of advanced methods is cost-effective when success

    VEGGIE is a prototype vegetable production unit for space designed by Orbital Technologies Corporation that is being developed to fly on the International Space Station. A modular plant rooting system "pillow" is being designed to support plant growth in VEGGIE under microgravity conditions. VEGGIE pillows are small self-contained packets of media with time-release fertilizer that can wick water passively from a root mat reservoir. Seeds are planted in pillows and the entire root system of a plant is contained as the crop develops, preventing loss into the spacecraft cabin. This study compared five media types and three lettuce cultivars in pillows growing in a VEGGIE analog environment.. Media consisted of a peat-based potting mix (Fafard #2,Conrad Fafard Inc., Agawam, MA), and a calcined clay, (arcillite, 1-2 mm sifted, Turface Proleague, Profile LLC, Buffalo Grove IL) as well as three different blends of the two, 70:30, 50:50, and 30:70. Lettuce cultivars tested were 'Sierra', a bi-colored French crisp Batavia lettuce, 'Outredgeous', a red romaine lettuce and 'Flandria', a green butter head variety. Plants were grown for 28 days, harvested, biometric data was obtained, and tissue mineral analysis was performed. For all cultivars, lettuce plants grown in the media blends were more productive than those in the individual media types. All cultivars showed bell-shaped curves in response to increases in arcillite / decreases in Fafard #2 for leaf area, fresh, and dry mass. Plants in 100% Fafard #2 and in 100% arcillite were stunted, but only those in higher levels of Fafard #2 (70% and 100%) had reduced shoot percent moisture, possibly indicating that mechanisms causing stunting differed. Variation in tissue nutrient content are consistent with this, with Mg and Mn highest in plants grown in 100% Fafard and decreasing as the concentration of arcillite increased. Color also varied with media, especially in the 'Sierra' lettuce, with plants grown in increasing levels

Hemodialysis has a major influence on the everyday life of patients and many patients report dissatisfaction with treatment. Little is known about which aspects of treatment are considered important by hemodialysis patients. The objective of this study was to rate the relative importance of different outcomes for hemodialysis patients and to analyze whether the relative importance differed among subgroups of patients.Patients and methods: Within the framework of a yearly questionnaire which is distributed among patients receiving hemodialysis by the largest hemodialysis provider in Germany, we assessed the relative importance of 23 outcomes as rated on a discrete visual analog scale. Descriptive statistics were used to rank the outcomes. Subgroup analyses were performed using Mann–Whitney U or Kruskal–Wallis tests.Results: Questionnaires of 4,518 hemodialysis patients were included in the analysis. The three most important outcomes were safety of treatment, health-related quality of life, and satisfaction with care. Further important outcomes were hospital stays, accompanying symptoms, hemodialysis

    Just one hundred years ago. Wilhelm Conrad Rontgen published his paper in Wurzburg describing X-rays and their effects, earning him the first Nobel Prize in Physics, presented in 1901. X-ray based diagnostic equipment revolutionized human diagnostics. A new milestone in the development of radiology was when Godfrey Hotmufield proposed to get additional anatomical information from a cross-sectional plane of the body by computer aided mathematical synthesis of an image from X-ray transmission data obtained from many different angles through the plane in consideration. The idea of the X-ray Computer Aided Tomography (CAT) was born, and the dramatic development of X-ray CAT imaging technology began, enhancing efficiency and scope of human diagnostics in human medicine. The numbers used to characterize the X-ray absorption in each picture element (pixel) of the CAT image are called ''CT'' or Hounsfield numbers (Hounsfield, 1979). The Nobel Prize was awarded to Hounsfield in 1979. X-ray Computer Aided Tomography system and software used were developed for humen medical purposes - mainly to detect anatomical physiological disorders - by all leading high-tech manufacturers in the world. As early as 1980, the potential of the new technique to be utilized in animal science was first recognized in Norway (Skjervold et al., 1981). In 1982, the Agricultural University of Norway acquired a Siemens Somatom 2 CAT system, and pioneering work started to apply X-ray CAT techniques in animal science. Based on the promising results obtained and published by the ''Norwegian school'' (Sehested, 1 984 Vangen, 1984 Allen and Vangen, 1984: Vangen and Standal, 1984), a research project proposal was prepared for the Hungarian Ministry of Agriculture and Food and the World Bank in 1985 to set up a digital imaging center at our Institute. The project was approved in 1986 (Horn, 1991a). The new digital imaging and diagnostic center started its operation in 1990, equipped first with a Siemens

    Full text: Medical imaging has undergone remarkable evolution over the past century. Since the discovery of the X-rays by (Wilhelm Conrad Roentgen), static emission tomography (Hal Anger) computed tomography (Godfrey Hounsfield and Alan Cormack), and magnetic resonance imaging (Paul Lauterbur and Peter Mansfield) there have been many other important discoveries and technical developments that have culminated in our current sophisticated multi-modality imaging systems. Nobel Prizes have been given for the discoveries of radioactivity (Marie Curie, Pierre Curie, and Henri Becquerel in 1903) and the positron (Carl Anderson in 1936) and for technical developments such as the radiotracer concept (George De Hevesy in 1943). Positron emission detection systems have developed since their first use in the 1950s to the high-resolution, high-sensitivity tomographic devices that we have today. In keeping pace with these milestones in the evolution of medical imaging, positron emission tomography (PET), and more recently integrated positron emission tomography-computed tomography (PET-CT), have now emerged not only as important research tools but also as significant diagnostic imaging systems in clinical medicine. The use of multi-modality imaging systems and 'smart' specific imaging agents will achieve the key task of accurate diagnosis, treatment evaluation, surveillance, and prognosis in individual patients. PET-CT instrumentation has continued to evolve rapidly, especially over the last decade A PET scanner is combined with a CT scanner into a single machine. The PET and CT components are mounted on the same aluminium support with the CT on the front and PET at the back. Metabolic information is obtained from the PET scanner (emission of annihilation photons) and anatomic information is obtained from the CT scan (transmission of X-Rays). In addition, the CT scan can be used to provide information needed for attenuation correction. The current generation of PET-CT scanners

    Full Text Available The ambition of this issue of Portal is to reach across the methodological boundaries of history, politics, literature and geography to apply their complementary perspectives to the study of identity and its relation to space and place, an aim that involves attempting to identify the many different ways the notoriously slippery concepts of identity and geography may intersect. For this issue we have selected articles that cast a fresh perspective on two areas where identity and geography intersect: the construction of identity through the imaginative recreation of place in literature: Mapping Literary Spaces; and the study of the shifting relationships of centre and periphery, exclusion and inclusion in urban settings and geopolitical confrontations: Social and Political Peripheries. Gerard Toal has written that geography is not a noun but a verb: it does not describe what space is but studies what we do with space, imaginatively and politically. The articles in this issue illustrate the exercise of the literary and political imagination and the role of materiality and memory in the creation of geographic representation. They show too a new awareness of the centrality of space in the constitution of identities, and the need for a new geocritical reading of its discourse, as the interrelations of place and community are played out on the many scales of social and political life, from the local to the global.   The special issue is organised thus: Introduction Matthew Graves (Aix-Marseille University & Liz Rechniewski (Sydney University: “Imagining Geographies, Mapping Identities.” I.

    Full text: Some activities of the EURADOS Working Group 9 (WG9) related to the radiation protection dosimetry of medical staff were funded by the European Commission in the framework of the CONRAD project, Work Package 7. The objective of WG9 was to promote and co-ordinate research activities for the assessment of occupational exposure to staff at workplaces in therapeutic and diagnostic radiology and nuclear medicine. At these workplaces, from the point of view of the individual monitoring for external radiation, the skin of the fingers is generally the limiting organ. Subgroup 1 of WG9 had as main objective the study of the use of extremity dosemeters in medical radiation fields. The wide variety of radiation field characteristics present in medicine together with the difficulties of measuring a local dose which should be representative for the maximum skin dose using one single detector, makes it difficult to perform extremity dosimetry with an accuracy similar to that of whole-body one. A recent intercomparison organised by WG9 showed that some types of dosemeters significantly underestimate or overestimate skin doses. Subgroup 1 carried out a thorough literature review on extremity dosimetry issues. It covered diagnostic and therapeutic nuclear medicine and PET, interventional radiology and cardiology, and brachytherapy. It has notably pointed out the consensus about the requirement of regular extremity dose monitoring for nuclear medicine and PET, and the great difficulty of measuring extremity doses for procedures in interventional radiology and cardiology, activities for which routine extremity dose monitoring has been found to be poor. Furthermore, information on the status of extremity dosimetry in medical applications and associated monitoring practices was gathered from 7 European countries: France, Germany, Greece, Ireland, Poland, Spain and Switzerland. Interpretation of the data was not easy because of the wide range of procedures involved and also

Many host countries give victims of torture the status of refugee and take care of them as far as basic needs; health care, professional reinsertion, and education. Little is known about the costs of torture. However, this knowledge could serve as an additional argument for the prevention and social mobilization to fight against torture and to provide a powerful basis of advocacy for rehabilitation programs and judiciary claims.Objectives: Development of a model for estimating the economic costs of torture and applying the model to a specific country.Methods: The estimation of the possible prevalence of victims of torture was based on a review of the literature. The identification of the socioeconomic factors to be considered was done by analogy with various health problems. The estimation of the loss of the productivity and of the economic burden of disease related to torture was done through the human capital approach and the component technique analysis.Case study: The model was applied to the situation in Switzerland of estimated torture victims Switzerland is confronted with.Results: When applied to the case study, the direct costs – such as housing, food, and clothing – represent roughly 130 million Swiss francs (CHF per year; whereas, health care costs amount to 16 million CHF per year, and the costs related to education of young people to 34 million CHF per year. Indirect costs, namely those costs related to the loss of the productivity of direct survivors of torture, have been estimated to one-third of 1 billion CHF per year. This jumps to

The morbidity, mortality and reduced productivity associated with obesity and its complications result in a major burden to health care costs. Obesity is a complex chronic medical syndrome often with multiple different etiologic factors in individual patients. The long term successful management of obesity remains particularly challenging and invariably requires a multifaceted approach including lifestyle and behavioral modification, increased physical activity, and adjunctive pharmacotherapy. Bariatric surgery remains a last resort though at present it has the best results for achieving sustained robust weight loss. Obesity pharmacotherapy has been very limited in its role for long term obesity management because of the past history of several failed agents as well as the fact that presently available agents are few, and generally utilized as monotherapy. The recent FDA approval of the fixed drug combination of phentermine and extended release topiramate (topiramate-ER (trade name Qsymia™ marks the first FDA approved combination pharmacotherapeutic agent for obesity since the Phen-Fen combination of the 1990s. This review details the history and clinical trial basis for the use of both phentermine and topiramate in obesity therapeutics as well as the results of clinical trials of their combination for obesity treatment in humans. The initial clinical approval trials offer evidence that this fixed drug combination offers synergistic potential for effective, robust and sustained weight loss with mean weight loss of at least 10

    Full Text Available Few discoveries in the history of science brought such significant progress as did the discovery of X-rays by the German physicist Wilhelm Conrad Röntgen in 1895. The finding did not only bring a revolution to the field of medicine but also to many other technical branches. With technological progress in the 20th century, medical roentgenology swiftly developed. The first significant step forward was the introduction of contrast media followed by others including computerised image data management and digital techniques. Medical diagnostics embraced other imaging methods based on other types of energy such as ultrasound and magnetic resonance imaging. The beginnings of roentgenology in the Slovene Lands go back to the year 1900. Bone fractures were the first to be imaged, followed by thoracic imaging and contrast imaging of the gastrointestinal tract. The use of roentgenology spread significantly after World War I, with the implementation in the following years of X-ray machines in all Slovenian hospitals, some spas and sanatoria. Gradually the need for an independent scientific institution emerged, which led to the establishment of the Roentgenological Institute for Slovenia and Istria in Ljubljana in 1923. At the same time radiology was developing also by other Slovenian hospitals.In the 1950s, Slovenian roentgenology increasingly stayed in touch with contemporary international development, updated its equipment and introduced new methods. The modern concept of centralised radiological management, comparable with that of modern European institutions, was realised in Ljubljana in 1973 after the relocation of the Radiological Institute to the new facilities at the Ljubljana University Medical Centre. The first computer tomography machine was installed in 1980, the first ultrasound machine was acquired in 1981, the first digital subtraction angiography (DSA machine was introduced in 1986 and the first magnetic resonance machine was installed in

    A big data geospatial analytics platform:Physical Analytics Information Repository and Services (PAIRS)Fernando Marianno, Levente Klein, Siyuan Lu, Conrad Albrecht, Marcus Freitag, Nigel Hinds, Hendrik HamannIBM TJ Watson Research Center, Yorktown Heights, NY 10598A major challenge in leveraging big geospatial data sets is the ability to quickly integrate multiple data sources into physical and statistical models and be run these models in real time. A geospatial data platform called Physical Analytics Information and Services (PAIRS) is developed on top of open source hardware and software stack to manage Terabyte of data. A new data interpolation and re gridding is implemented where any geospatial data layers can be associated with a set of global grid where the grid resolutions is doubling for consecutive layers. Each pixel on the PAIRS grid have an index that is a combination of locations and time stamp. The indexing allow quick access to data sets that are part of a global data layers and allowing to retrieve only the data of interest. PAIRS takes advantages of parallel processing framework (Hadoop) in a cloud environment to digest, curate, and analyze the data sets while being very robust and stable. The data is stored on a distributed no-SQL database (Hbase) across multiple server, data upload and retrieval is parallelized where the original analytics task is broken up is smaller areas/volume, analyzed independently, and then reassembled for the original geographical area. The differentiating aspect of PAIRS is the ability to accelerate model development across large geographical regions and spatial resolution ranging from 0.1 m up to hundreds of kilometer. System performance is benchmarked on real time automated data ingestion and retrieval of Modis and Landsat data layers. The data layers are curated for sensor error, verified for correctness, and analyzed statistically to detect local anomalies. Multi-layer query enable PAIRS to filter different data

    Due to the potential consequences of an accident in a nuclear facility, a national emergency organization was constituted in France, in order to have the capacity to implement countermeasures necessary to protect the surrounding population from the consequences of radioactive releases. The Institute for Nuclear Safety and Protection (IPSN), the technical support of the French nuclear safety authority, provides the technical support needed in this decision-making process. So, in the event of an accident arising at a nuclear facility, the IPSN would set up an Emergency Response Technical Centre (ERTC) at Fontenay-aux-Roses (Hauts-de-Seine). The IPSN's objectives are: - to diagnose the state of the nuclear facility and to monitor its development, - to prepare prognosis for the evolution of the accident and to give an estimation of the associated consequences according to the situation evolution, - to estimate the risk of radioactive releases and the consequences on man and on the environment, mainly on the basis of weather forecasts and on the prognosis. This diagnosis-prognosis approach is build-up, in case of a PWR, with the information on the state of the installation given by the concerned site via audio-conference system and faxes and by the security panels of the nuclear power plant. To perform its missions, the ERTC, which has to be both safe (a failure must not prevent the management of crisis situation) and secure, uses multiple telecommunication resources to dialogue with partners and also mapping computer systems, data bases and software tools: - the SESAME system, which gives, during an accident of a PWR, a calculation method for the diagnosis-prognosis aforesaid, - the CONRAD system, which calculates the atmospheric dispersal of radioactive substances and consequences in the environment in the early phase of an accident, - the ASTRAL code, which allows to cope with long-lasting situations. In order to be operational, the IPSN experts regularly undergo

    Full Text Available A China that is in a frenzied state of economic boom and potential social instability, which is most vividly represented in its architectural and urban developments, is, I hope I will convince you, ephemeral. A quite different China, perhaps is not so visible as its new buildings and cities, is metaphorically ‘handmade’. I should like to extend the meanings of the handmade to the more stable and long lasting attitudes towards social life, and even mortality. My sources for the second China are partially from literature (not from architecture. With the construction boom since the mid-1990s, mainstream Western architectural journals and galleries have been racing to expose new architecture in China; celebrity Western architects have been winning major commissions in China: the 2008 Beijing Olympic Games is a case in point. The sheer quantity and speed of China’s development, as evidenced in architecture and urbanisation, causes an ‘unbearable lightness of being’ (to paraphrase Milan Kundera. Does all this then suggest that China, as solidified in its buildings and cities, is no longer ‘handmade’ in the sense that memory and a sense of history are redundant (particularly for a country that has a recorded history of more than 5000 years, which have been so lovingly recorded in handmade artefacts? The true meaning of the handmade, which absorbs labour — an ‘honourable labour’ as Joseph Conrad lovingly put it in his Mirror of the Sea, as well as memory, like that of a home, is a static artefact, which harbours our changing emotion, the frailties of human life, and indeed, the growing awareness that comes with time of our mortality: the handmade offers the necessary enshrinement of life’s vulnerability. Let me assure you, the seemingly fast-changing China, as represented in its new architecture and city forms, as well in its frenzied urbanisation and booming economy, is but a smoke screen. It is, in other words, ephemeral. The

    Full Text Available Güvenlik çalışmaları Soğuk Savaş’ın sona ermesinden sonraki dönemde giderek genişleyen bir günde­me sahip olmuştur. Bu makalede genişleyen güvenlik gündeminde yer alan insani güvenlik kavramı bağlamında çevresel güvenlik konusu incelenecektir. Çalışma öncelikle insani güvenlik kavramının ne zaman ortaya çıktığını ve farklı insanı güvenlik tanımlarından bahsetmektedir. 1994 yılı Birleşmiş Milletler Kalkınma Raporu insani güvenlik kavramının ortaya çıkışı açısından dönüm noktası olurken, tanımlar arasında iki tanesi ağırlık kazanmıştır. Geniş tanımlamada yoksulluk ve kalkınma temel dinamikler olarak alınırken dar insani güvenlik tanımlamasında fiziki şiddetin kullanılması baz olarak alınmıştır. Öte yandan, insani güvenlik etrafındaki tartışmaların önemli ölçüde normatif ve kuramsal boyutlara sahip olduğu görülmektedir. Bu sebeple makale başlıca uluslararası ilişkiler teorilerinin in­sani güvenlik olgusuna nasıl baktıklarına da yer vermektedir. Realist teoriler insani güvenlik kavramı ile ilgilenmezken liberal, inşacı ve eleştirel kuramların insani güvenlik olgusu ile ilgili oldukları görül­mektedir. Çalışmanın daha sonraki bölümü başta küresel ısınma olmak üzere çeşitli çevre sorunlarının insani güvenlik ve devletlerarası ilişkiler açısından nasıl tehlike oluşturduklarını analiz etmektedir. Bu bağlamda önemli bir konu çevresel güvensizlik ya da çevre felaketlerinden kaynaklanan devlet içi ve uluslararası göçlerin devletlerin istikrarını bozabilecek olması ve devletlerarası çatışmalara yol açabilme­sidir. Çevresel güvenlik sorunları Darfur ve Suriye’de olduğu gibi sıcak çatışmaların ortaya çıkmasında önemli bir etkiye sahip olabilmektedirler.

Öz’ün romanında da uzamsal değişimlere bağlı olarak tekil özneler, tek tipleştirilerek metindeki karşılığıyla “Nuri”lere dönüşür. Bireyin kendi kimliğini yitirerek tek tipleşmesinin temelinde suç üretimi vardır. Suç üretimi ise uzama göre şekillenir. Romanda uzama göre değişen çektirilen azaplar, Foucault’un da belirttiği gibi özneyi hiyerarşik düzleme yerleştirir ve varoluşu sona erdirir. İktidar, özneyi kişisel mekânından ayırıp önce sorgu odasına ardından da hapishaneye götürerek onu düzenin bir parçası hâline getirmiş ve nesneleştirmiştir. İktidarın sindirici etkisi, anlatı düzlemindeki ikinci tekil anlatıcının varlığıyla daha da somutlaşmış; kurulan düzen içerisinde özne yitimi gerçekleşmiştir.

    Full Text Available In November 1895, X-rays were inadvertently discovered by the German physicist Wilhelm Conrad Roentgen. Roentgen provisionally named the new rays as X-rays using the mathematical label for something unidentified. Roentgen's initial manuscript, "On A New Kind of Rays" (άber eine neue Art von Strahlen, was published two months later and in 1901, he received the first ever Nobel Prize in Physics “in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays" subsequently named after him. He himself refused to take out patents, intending to the free use of X-rays for the benefit of mankind. Today, Wilhelm Conrad Roentgen is honoured as the father of diagnostic radiology.1,2 Since the inadvertent discovery of X-rays, conventional radiography has developed greatly and mostly has been replaced by digital radiography equipments which convert X-ray images to electronic data that can be studied using a monitor and archived on a computer disk. Digital techniques permit the radiographs to be viewed instantaneously, additionally allow specific areas of the image to be enlarged, and the contrast of the images can be manipulated to provide greater visibility of the abnormality.1 The anatomical details and sensitivity of the newer modalities is now of a high order and the use of imaging for ultrastructural diagnostics nanotechnology, functional and quantitative diagnostics and molecular medicine is steadily increasing. Most recently the improved imaging clarity and tissue differentiation in a number of clinical situations has dramatically increased the spectrum of the diagnostic information and even in many cases revealing the pathology without the requirement of invasive tissue sampling.3 Eventually radiology is now the prime diagnostic aid for many diseases and also has a vital role in monitoring treatment and predicting outcome. Recent advancements in this field bring a number of imaging modalities which have

The quoted uncertainties were determined by marginalization with the CONRAD code. The value of the K1 parameter calculated with the NJOY processing system is 1161 barns. The large fluctuations of the prompt neutron multiplicities were correctly reproduced with a phenomenological decomposition of the multiplicity that involved the one-step (or direct) fission reaction and the two-step (n,γf) process. Below 2.5 keV, the (n,γf) process was calculated by introducing two additional partial widths (Γ γf 7.3 meV for J=0 + and Γ γf = 4.2 meV for J=1 + ). The final result was in good agreement with the prompt neutron multiplicity of JEFF-3.1.1. Performances of the new 239 Pu evaluation were tested over a broad set of integral data (ICSBEP, mock-up experiments performed in the CEA facilities and in power reactors). An overall good agreement was achieved between the calculations and the experimental results. The performances are similar to those of the 239 Pu evaluation of JEFF-3.1.1. More integral feedback will be obtained via the NEA WPEC Subgroups 39 and 40. The present results allow identifying several priorities for future experimental and evaluation works. For the resolved resonance range, new transmission measurements of the first broad s-wave resonance at 0.3 eV are needed as is capture yield over a large energy range. At low energy, the SAMMY/CONRAD analysis relies on a single transmission data set measured by Bollinger in 1958. For the capture cross-section the available data set was measured by Gwin in 1971. High resolution measurements of neutron multiplicity are also required. Two problems occur during the evaluation work. The first one concerns the Resonance Parameter Covariance Matrix. A concise method for storing and communicating large RPCM is needed. In the present work, an artificial reduced neutron width selection was used to reduce

    Since the era of Kraepelin and Bleuler, schizophrenia has been considered to be very difficult to cure. Even if all symptoms of its acute phase have disappeared completely, it is customary to use the terms say "remission" instead of "cured". The chief reason why they have been unwilling to say "cured" is that, even if the present state seems to be "cured", there will be surely another attack in near future, so, the non-symptomatic state should not be understood as "cured". Whether schizophrenic patients can be cured or not is one of the great problems of modern psychiatry. Is there no probability for them to be cured? Recently, after a 30 years gap, I came to meet a man who had had a schizophrenic attack of the psychomotoric type when he was 25 years old and had been sent to the mental hospital where I had been at work and, by chance, had engaged in his treatment. After about 5 months' of acute state, he came at, so to speak, "Residualzustand" (Conrad) for about 1 year and then got insight into his psychosis. After the discharge, he had visited me as an outpatient once a month regularly. About one year thereafter, the change of my work place made us separate from each other. Since then, he stopped visiting the doctor and also stopped taking anti-psychotic drugs. He married at 29 years old and had 2 daughters and a son. In addition, he had started to work for his father's business. After his father's death, he became the owner of 5 shops and the supervisor of 50 workers. Is he not yet "cured"? Is he only in the state of "remission" even now? According to the principle of Kraepelin and Bleuler, he is not "cured" yet, because he will surely have a psychotic exacerbation in future. I wonder then, what is the difference of the two concepts of "remission" and "cured", and how is it possible to change "remission" to "cured"? Even Bleuler, E. has written in his world-famous textbook that the longer the duration of remission after the last attack, the smaller the

    Full Text Available The decadence that the Decadents identified in their own civilization was recognized through the model of Roman Empire, although they thought that the Romans were, even in their decadence, much more vigorous than the modern "cerebral" decadents. The figures of the late Empire, which fused the over-ripeness of culture with barbarism, were great even in their decline; the ancient uninhibited transgressions and vices fascinated the decadents although even the imagined debaucheries exhausted the modern decadents. Des Esseintes is, of course, a paradigmatic figure, connecting extreme weakness and fragility of the nervous system with wild sadistic dreams. He is capable of producing vigorous mental images, imagining sublimely horrible figures and emblems of disease, which fell on a fertile ground in later decadent writings. At the same time, the idea of the savage and the primitive which had underwent a radical change, when the romantic idea of the noble savage was replaced by the primitive as the lowest order of humanity, became fashionable even among many Decadents. This debauched barbarian or savage (whose representatives or relics the survived "primitive cultures" were marked the beginnings of human culture and was the suppressed foundation of all developed cultures. The danger of the return of this primitive side of man could threaten even the most civilized individuals or nations if the ties and restraints of culture were loosened (Joseph Conrad's Heart of Darkness represents this perfectly.  For the decadents, who did not see their own civilization in the terms of progress any more, and embraced ideas of entropy, dissolution and return to a state of new barbarism, the idea of the decline of their culture, thus, could become connected with the idea of the primitive "in us", the primitive lurking in the psyche of every individual and the primitive that was built in the culture itself. As the primitive became, increasingly, identified not only

  16. Joint Inversion Of Local And Teleseismic Data For The Crust And Mantle Structure Of The Chinese Capital Region

    2004-12-01

    The Chinese Capital (Beijing) region is located in the intersection of the Yanshan and Taihangshan uplifts in North China. It is one of the regions with the strongest continental earthquakes in the world such as the 1976 Tangshan earthquake (M 7.8) which killed 240,000 people. Hence the determination of the crust and mantle structure of this region is very important for understanding the regional tectonics and for the reduction of earthquake hazards. Since October 2001 a new digital seismic network with 107 stations has been installed in this region, which is the most advanced and densest regional digital seismic network in mainland China. In this study we used 48750 P-wave arrival times from 2973 local events and 12249 travel time residuals from 234 teleseismic events recorded by this new digital seismic network. We adopted the local and teleseismic joint inversion approach by Zhao et al. [1994] and obtained a high-resolution three-dimensional (3-D) P-wave velocity model of the crust and mantle down to a depth of 1000 km. The resolution is 50 km in the horizontal direction, and in depth it is 4-17 km in the crust and 30-50 km in the mantle. The complex morphology of the Conrad and Moho discontinuities was taken into account in the tomographic inversions. Our 3-D velocity model provides new insights into the geological structure and tectonics of this region. The velocity images of the upper crust reflect well the surface geological, topographic and lithological features. In the North China Basin, the depression and uplift areas are imaged as slow and fast velocity belts oriented in NE-SW direction. The trend of velocity anomalies is the same as that of major faults and tectonics. Paleozoic strata and Pre-Cambrian basement rocks outcrop widely in the Taihangshan and Yanshan uplift areas, which exhibit strong and broad high-velocity(high-V) anomalies in our tomographic images, while the Quaternary intermountain basins show up as small low-velocity(low-V) anomalies

    West, Inc., had already prepared a document discussing geologic hazards in the area, titled 'Exhibit B Topic Report 6 - Geological Resources' (Fugro West, Inc., 2007); hereafter, this will be called the 'Geological Resources document'. The USGS agreed to evaluate the information in the Geological Resources document regarding (1) proximity of active faults to the proposed project, (2) potential magnitude of seismic events from nearby faults, (3) thoroughness of the assessment of earthquake hazards in general, (4) potential hazards from ground rupture and strong shaking, (5) potential hazards from tsunamis, and (6) other geologic hazards including landslides and debris flows. Because two new earthquake probability reports were scheduled to be released in mid-April, 2008, by the USGS and the California Geological Survey (CGS), the USGS suggested a 6-month review period to enable a thorough incorporation of this new information. Twenty-seven scientists from the USGS and the CGS reviewed various sections of the Geological Resources document. This report outlines our major conclusions. The appendix is a longer list of comments by these reviewers, grouped by section of the Geological Resources document. Before discussing our reviews, we first provide a brief overview of geologic hazards in the proposed site area. This report is a snapshot in time and any future work in the area will need to take into account ongoing research efforts. For example, USGS scientists collected seismic reflection data in the spring of 2008 to study the structure and seismic potential of several faults in the area. Their interpretations (Conrad and others, 2008a and 2008b) are too preliminary to be included in this report, but their final results, along with other researchers' studies in the project area, should be considered in any future work on the Deepwater Port project.

  18. The Mafic Lower Crust of Neoproterozoic age beneath Western Arabia: Implications for Understanding African Lower Crust

    We review evidence that the lower crust of Arabia - and by implication, that beneath much of Africa was formed at the same time as the upper crust, rather than being a product of Cenozoic magmatic underplating. Arabia is a recent orphan of Africa, separated by opening of the Red Sea ~20 Ma, so our understanding of its lower crust provides insights into that of Africa. Arabian Shield (exposed in W. Arabia) is mostly Neoproterozoic (880-540 Ma) reflecting a 300-million year process of continental crustal growth due to amalgamated juvenile magmatic arcs welded together by granitoid intrusions that make up as much as 50% of the Shield's surface. Seismic refraction studies of SW Arabia (Mooney et al., 1985) reveal two layers, each ~20 km thick, separated by a well-defined Conrad discontinuity. The upper crust has average Vp ~6.3 km/sec whereas the lower crust has average Vp ~7.0 km/sec, corresponding to a granitic upper crust and gabbroic lower crust. Neogene (<30 ma) lava fields in Arabia (harrats) extend over 2500 km, from Yemen to Syria. Many of these lavas contain xenoliths, providing a remarkable glimpse of the lower-crustal and upper-mantle lithosphere beneath W. Arabia. Lower crustal xenoliths brought up in 8 harrats in Saudi Arabia, Jordan, and Syria are mostly 2-pyroxene granulites of igneous (gabbroic, anorthositic, and dioritic) origin. They contain plagioclase, orthopyroxene, and clinopyroxene, and a few contain garnet and rare amphibole and yield mineral-equilibrium temperatures of 700-900°C. Pyroxene-rich and plagioclase-rich suites have mean Al2O3 contents of 13% and 19%, respectively: otherwise the two groups have similar elemental compositions, with ~50% SiO2 and ~1% TiO2, with low K2O (<0.5%) and Na2O (1-3%). Both groups show tholeiitic affinities, unrelated to their alkali basalt hosts. Mean pyroxene-rich and plagioclase-rich suites show distinct mean MgO contents (11% vs. 7%), Mg# (67 vs. 55), and contents of compatible elements Ni (169 vs. 66 ppm

    In 1895, exactly one hundred years, ago, a chance discovery in Wurzburg, Germany, marked the dawn of a new science - atomic physics. Other discoveries and new insights followed quickly. Apart from interruptions for two World Wars, this rapid succession of breakthroughs continued for 88 years. A new series of occasional articles in the CERN Courier will look back to what was happening one century ago. In Wurzburg on 8 November 1895, Wilhelm Conrad Rôntgen became an immortal legend. Interested in the effects of ultra-violet radiation, he covered a cathode-ray discharge tube with black paper and darkened the room. With the glow from the tube hidden, Rôntgen was surprised to see a fluorescent screen two metres away light up. For several weeks, Rôntgen hid in his laboratory, finding out more about the mysterious penetrating 'X' rays, produced when the cathode rays hit the end of the discharge tube. Since the time of Faraday, the glow produced in an evacuated tube when an electric current was passed through had intrigued physicists and entertained the public. Nobody understood what these cathode rays were. William Crookes in the UK, who had narrowly missed making the Rôntgen discovery, surmised they were a new 'fourth state' of matter. Some scientists said the phenomena were due to radiation, others said particles. Also in 1895, a young physics student named Ernest Rutherford arrived in Britain from New Zealand with a scholarship for further study. The scholarship, awarded to a New Zealand student only once every few years, had initially been given to a young chemist, but who decided at the last minute to get married and stay in New Zealand. The scholarship passed to Rutherford, who, thanks to a change in regulations, was able to use it at the Cavendish Laboratory in Cambridge, under J.J. Thomson. In New Zealand, Rutherford had carried out experiments on radio telegraphy. He took his transmitter to Britain and at Cambridge continued his pioneer

This motto, used by Professor Jean-Franois Moreau in his presentation ‘A Century uroradiology in Europe 1896 -1996’, is the occasion, with his consent and participation to complement the presentation not only with what comes as a change in our profession in recent years, but also to celebrate milestones in the development of uroradiology in Bulgaria. One of the major health problems in Europe, not only in the late 19th century, but today is renal calculi. For this reason, five months after the described by Wilhelm Conrad Roentgen X- rays attempts to use them in medical practice by urologists namely in seeking opportunities to demonstrate calculi began. What you will learn: This justifies the first phase, covering 1896-1929, has not only uroradiology but of radiology as a whole, in which it is a hobby of the urologists. Summarizing the main points as in the technical development of radiological equipment, but above all the introduction of diagnostic methods, some of which have not lost their relevance and today, this period naturally ends with one of the most epochal discoveries in medicine and first diagnostic method combining morphological with functional diagnostics - excretory urography . The second step, covering the period of 1929-1960, is characterized by increasing further improvement of the equipment, but also of the applied diagnostic methods, as the urologist is still leading in applying these methods, but now with the technical assistance of the radiologist. After World War II, this approach began to change, besides the appearance of chapters on uroradiology in major guidelines in diagnostic radiology, new methods have been developed, and including vascular contrast diagnostic are made and implemented by radiologists. The third stage, cover the period 1960-1980, entitled ‘Fathers of uroradiology’ account entry of CT low-osmolar nonionic

    Full Text Available Abstract – This study explores the web-mediated genre of TED (Technology, Entertainment, Design talks, speech events whereby experts in their field disseminate knowledge from different domains (e.g. science, technology, design, global issues addressing an audience of both co-present participants and web-users all over the world. The aim of this study is to investigate the way academics convey epistemic stance (Conrad, Biber 2000 and build up their image as experts on the TED stage. To this purpose, a contrastive analysis was carried out comparing two corpora of spoken discourse, i.e. a corpus of TED talks and a corpus of MICASE university lectures from different disciplines. Although in both genres the speaker is an academic, both the communicative purpose and audience expectations differ substantially in the two contexts under scrutiny. This comparison highlights some distinguishing traits of TED talks and provides a better insight into this genre. Adopting a corpus-based approach, attention is first paid to the most recurrent epistemic lexical verbs (ELVs and to the use of first and second person pronouns in the two corpora. The qualitative analysis then focuses on similarities and differences in the discourse functions of the four most frequent ELVs (see, show, know, think and of their clusters when they combine with first and second person pronouns in the two corpora. Previous studies in the field of English for Academic Purposes (Rounds 1987; Fortanet 2004; Walsh 2004; Artiga León 2006; Bamford 2009 are referred to as a starting point to investigate a novel, unexplored pragmatic space (i.e. that of TED wherein academics accomplish purposes other than merely disseminating knowledge and training students, such as promoting their research and building up their image as experts.

    differences can be detected between LCZ classes ('inter-LCZ differences'). Results show that most 'built-up' LCZ classes in the study region are represented by CWS, while only few CWS are located in 'natural' LCZ classes (i.e. in inner-city parks or in rural areas). T as measured by CWS showed overall good agreement with data from a network of professional weather stations throughout the year, though for some LCZ classes mean monthly deviations were up to 1 K. Intra-LCZ variability of T was especially pronounced during night-time hours and during summer months. We found significant inter-LCZ differences in T mainly for dissimilar LCZ classes and during night-time. Our results indicate the suitability of CWS data for T monitoring of specific LCZ classes and the applicability of this data set for further scientific research. Bechtel, B., P. J. Alexander, J.

Leadership styles are important organizational antecedents, especially in influencing employee’s motivation, job satisfaction, and teamwork. There is limited research exploring this relationship among health workers in resource-limited settings such as Uganda. The aim of this study was to examine the relationship between transformational, transactional, and laissez-faire leadership styles and motivation, job satisfaction, and teamwork of health workers in Uganda. Method: We conducted a cross-sectional study in 3 geographic regions of Uganda in November 2015, using self-administered questionnaires with 564 health workers from 228 health facilities. Data were collected on health workers’ perception of leadership styles displayed by their facility leaders, their level of motivation, job satisfaction, and team work. Using Pearson correlation, relationships among variables were identified and associations of the components of leadership styles with motivation, job satisfaction, and teamwork was found using multivariable logistic regression. Results: Health workers in Uganda preferred leaders who were transformational (62% compared with being transactional (42% or laissez-faire (14%. Transformational leadership was positively correlated with motivation (r=0.32, job satisfaction (r=0.38, and team work (r=0.48, while transactional leadership was positively correlated with job satisfaction (r=0.21 and teamwork (r=0.18.

    Full Text Available Este artigo retrata a história recente da transformação do conceito da impotência, como desordem psicossexual, em disfunção erétil, considerada como uma doença de etiologia principalmente orgânica. Demonstra sucessivamente como a impotência masculina constituiu uma abrangência global de todo o ciclo da resposta sexual, e ainda, uma violação da identidade e da autoimagem; como o relacionamento entre casais se transformou progressivamente em dificuldade e como a falta de um órgão claramente circunscrito pode ser o objeto de um "simples" tratamento medicamentoso. Este processo foi analisado a partir de modelo sequencial da medicalização (Conrad, que permite compreender a intervenção dos diferentes atores envolvidos (cientistas, médicos, industriais, políticos, empresários. Compreende-se, assim, como as descobertas científicas são selecionadas e desenvolvidas de acordo com seu potencial industrial e são aplicadas às pesquisas clínicas; como entidades clínicas são reconceitualizadas e medidas através de investigações epidemiológicas na população em geral e como são criados os ensaios clínicos que levam à criação de um medicamento. Em seguida, observam-se como os atores da saúde pública e os políticos intervêm para dar legitimidade ao novo problema criado. Por fim, avalia-se a possibilidade da desmedicalização de problemas com o uso não-médico do medicamento, no contexto do desenvolvimento da autoprescrição na Internet.This paper delineates the history of the recent transformation of the concept of impotence - from a psycho-social disorder to a disease with an organic etiology. Then it shows how male impotency, which globally affected the entire sexual response cycle, even acted upon self-image and the representation of the couple - progressively became a disorder as the failure of a well controlled organ liable to undergo a single medicinal treatment.

    2005-12-01

    Albert G. Petschek died suddenly 8 July 2004. He enjoyed good health and was very active professionally and personally until his death. He was highly respected, particularly in theoretical physics, for his deep, broad-ranging analytical powers, which resulted in contributions to nuclear physics, astrophysics, atmospheric physics, quantum mechanics, and quantum computing. Albert was born in Prague, Czechoslovakia in 1928. His extended family left Czechoslovakia when its sovereignty was threatened by Germany in 1938 and settled throughout the Western Hemisphere. Albert's father, a banker, settled in Scarsdale, near New York City. Albert graduated from White Plains High School and obtained his BS from MIT in a program accelerated during World War II. While getting his masters degree at the University of Michigan, Albert met his wife, Marilyn, also a physics masters student. In 1953, Albert obtained his PhD from the University of Rochester working with Robert Marshak on aspects of nuclear theory, and joined Los Alamos National Laboratory (LANL), then Los Alamos Scientific Laboratory. Soon thereafter, Albert's younger brother, Harry, also became a PhD physicist. Harry is now well known in plasma physics for reconnection theory. At Los Alamos, Albert worked closely with Carson Mark, Marshall Rosenbluth, and Conrad Longmire designing the first thermonuclear weapons. His derivation of several radiation diffusion solutions, later published as LAMS 2421, remains a classic in its field, as does work on nuclear theory done with Baird Brandow and Hans Bethe during a sabbatical at Cornell in 1961. Bethe was a frequent visitor to Los Alamos and a close friend. A devoted family man, Albert also valued Los Alamos as a safe, stimulating environment for raising an active family. Like many of the scientists at Los Alamos, Albert enjoyed its ready access to outdoor activities such as hiking and skiing. Albert often combined his passions for intellectual activity and the outdoors

    . Methane absorbs infrared radiation in the troposphere, as do CO2 and H2O, and is an important greenhouse gas (Lacis et al., 1981; Ramanathan et al., 1985).A number of review articles on atmospheric CH4 have appeared during the last 15 years. Cicerone and Oremland (1988) reviewed evidence for the temporal atmospheric increase, updated source estimates in the global CH4 budget, and placed constraints on the global budget, emphasizing that the total is well constrained, but that the constituent sources may be uncertain by a factor of 2 or more. This paper was part of a special section in Global Biogeochemical Cycles that resulted from a 1987 American Chemical Society Symposium, "Atmospheric Methane: Formation and Fluxes form the Biosphere and Geosphere." Tyler (1991) and Wahlen (1993) emphasized new information on stable isotopes of CH4 and 14CH4, respectively. Several reviews deal with the microbially mediated CH4 oxidation. King (1992) reviewed the ecology of microbial CH4 oxidation, emphasizing the important role of this process in global CH4 dynamics. R. S. Hanson and T. E. Hanson (1996) reviewed the physiology and taxonomy of methylotrophic bacteria, their role in the global carbon cycle, and the ecology of methanotrophic bacteria. Conrad (1996) reviewed the role of soils and soil microbial communities as controllers of CH4 fluxes, as well as those of H2, CO, OCS, N2O, and NO. Two meetings focusing on CH4 biogeochemistry were held in 1991: an NATO Advanced Science Workshop held at Mt. Hood, OR, and the Tenth International Symposium on Environmental Biogeochemistry (ISEB). A dedicated issue of Chemosphere (26(1-4), 1993) contains contributions from the NATO workshop; two additional volumes (Khalil, 1993 and Khalil, 2000) contain a report of the workshop and updates of important topics. Contributions to the ISEB meeting are presented in Oremland (1993). Wuebbles and Hayhoe (2002) reviewed the effects of CH4 on atmospheric chemistry and examined the direct and indirect

    Freshwater mussels of the genus Diplodon (Bivalvia, Hyriidae) are the most abundant bivalve (today and in the past) in freshwater bodies at both sides of the South-Andean Cordillera. There are about 25 different Diplodon genera in Argentina and Chile that could be assigned almost completely to the species Diplodon chilensis (Gray, 1828) and two subspecies: D. ch. chilensis and D. ch. patagonicus; this latter species is found in Argentina between Mendoza (32˚ 52' S; 68˚ 51' W) and Chubut (45˚ 51' S; 67˚ 28' W), including the lakes and rivers of the target area, the Nahuel Huapi National Park (Castellanos, 1960). Despite their wide geographic distribution, Diplodon species have only rarely been used as climate archives in the southern hemisphere. Kaandorp et al. (2005) demonstrated for Diplodon longulus (Conrad 1874) collected from the Peruvian Amazonas that oxygen isotopic patterns in the shells could be used in order to reconstruct the precipitation regime and dry/wet seasonal of the monsoonal system in Amazonia. Although this study demonstrated the potential of Diplodon in climatological and ecological reconstructions in the southern hemisphere, as of yet, no systematic study of Diplodon as a multi-proxy archive has been undertaken for the Patagonian region. In this work we present sclerochronological analyses supported by ^18Oshell in recent mussel of Diplodon chilensis patagonicus (D'Orbigny, 1835) collected at Laguna El Trébol (42°S-71°W, Patagonia Argentina), one of the best studied water bodies in the region for paleoclimate analysis. Water temperature was measured every six hours for one year using a temperature sensor (Starmon mini®) placed at 5m depth in the lake, close to a mussel bank. Additionally, ^18Owater was measured monthly for the same time range.g^18Oshell values obtained by micro-milling at high spatial resolution in the growth increments of three Diplodon shells were compared to these records, and to air temperature and

    de las radiaciones ionizantes. En 1924 apenas hacía un año que se acababan de celebrar en París los primeros 25 años del descubrimiento del radium por los esposos Curie; y la misma Madame Curie, solemne y vestida de negro desde la muerte trágica de su marido, había presidido las ceremonias de inauguración de la Fundación Curie, como la rama clínica y de radioterapia de su connotado Instituto de Radium. Transcurriendo un año, en 1925, se celebraría el trigésimo aniversario del descubrimiento de los Rayos X por Wilhelm Conrad Roentgen. Tanto el radium como los Rayos X venían ya aplicándose por dos o más décadas al tratamiento del cáncer. Los estudios experimentales sobre la influencia de la diferenciación celular en el efecto de la radioterapia, hechos en Lyon por Claudius Regaud, histólogo destacado, habían llamado la atención de Madame Curie y del eminente bacteriólogo y médico Emile Roux quienes lo habían puesto, al finalizar la primera Guerra Mundial, a dirigir los trabajos en el Laboratorio de Radiofisiología del Instituto Pasteur y a sentar las bases científicas de la Fundación...

    Can you think of living without the World Wide Web, e-mail, DVDs, CD-ROMs, the bar code scanner, mobile phones or high-efficiency solar cells? I cannot. These systems are part of the backbone of our modern civilization. And they have something in common: they are all devices based on the double heterostructure. Zhores Alferov (and independently Herbert Krömer) proposed its concept and its usefulness for semiconductor lasers in 1962, two years after the first demonstration of the first (solid-state) laser. InP-based double heterostructure lasers are today, and have been for more than 20 years, the enabling light sources for optical fiber communication, sending their photonic bits around the globe at enormous and ever-increasing rates. In 2009, 61% of the 500+ billion world market for laser systems was based on semiconductor lasers. Obviously a straightforward success story? Not really at the beginning, rather the kind of survival story of somebody who was producing an enormous number of ideas and trying to make them reality; his production of ideas has not yet stopped after 60 years of professional life. Let's have a look back at how it started. Zhores Alferov was born 80 years ago on 15 March 1930 in Vitebsk in eastern Byelorussia, an area where 47 years before him the famous painter Marc Chagall had been born. His parents believed in socialism and named him after the French socialist Jean Jaurès, the author of J'accuse. The war came when he was an adolescent and his admired older and only brother was killed in 1944 at the battle of Stalingrad. Despite the turmoil of war and post-war times he finished school successfully on time, was admitted to the V I Uljanov Electrotechnical Institute in Leningrad, studied physics and graduated there in 1952. In 1953 he started work at the Physico-Technical Institute in Leningrad, founded by Abraham Ioffe, the first PhD student of Conrad Rèntgen in Munich. Ioffe had initiated systematic studies of semiconductors at this

    Reliable measurement of internal bodily substances and structures is one of the cornerstones of modern medicine. Progress in cancer medicine, like that in many medical fields, must encompass and take advantage of progress in the physical sciences. Historically, the development and refinement of physical sciences-based detection of biological entities precedes periods of great advancements in therapies. To treat broken limbs and arthritis, we are indebted to Conrad Roentgen's discovery of x-rays by which we can evaluate the bones; to apply gamma knife therapy for cancer, we are indebted to Marie Curie's discoveries about radioactivity by which we can eradicate tumors; to manage the complications of diabetes, we are indebted to Tom Clemens, Ames Pharmaceuticals and Dick Bernstein's refinement of direct blood glucose measurement technology by which we can count, hour-to-hour, the waxing and waning of blood sugar levels; to understand anything at all on the cellular level, we are indebted to Antonie van Leeuwenhoek's microscope, by which we can see our cells. The application of physical sciences perspectives to biological and medical problems has a long and productive history. As of late, however, the increasing compartmentalization of science and exponential increases of knowledge in both arenas has resulted in a rift between the two. The NCI has initiated a research network establishing multiple centers of investigation, the Physical Sciences in Oncology Centers (http://physics.cancer.gov), which seek to mend the rift. Each headed by a pair of investigators, one in the physical sciences and one in the biological sciences, the centers seek to bring the advances and breakthroughs of the physical sciences world to bear on the question of cancer. This issue of physical biology contains a series of articles exploring the utility and applicability of a new method for measuring cancer as it spreads, developed at the Scripps Physical Oncology Center.

    asteroids that came close to the earth, the official organization for attending to discoveries of asteroids (more than 99% of which are located in a belt between Mars and Jupiter) is the Minor Planet Center. Also operated by the International Astronomical Union, the MPC was located until 1978 at the Cincinnati Observatory. In that year the director, Dr. Paul Herget, was retiring, and it was necessary for the Center to find a new home. Accordingly, the IAU asked Dr. Marsden also to take over the direction of the MPC. Thanks to the transfer of associate director Conrad Bardwell with the MPC records from Cincinnati, this task was rendered easier. While the CBAT and the MPC still maintained their separate entities, there was a lot of common ground between them. Dr. Marsden was therefore able to introduce some efficiencies into their combined operation. On Mr. Bardwell's retirement at the end of 1989, Gareth Williams joined the MPC staff and later became associate director. The advances in electronic communication during the 1990s also permitted improvements in MPC operation. Perhaps the most important of these was the development, in 1996, of the Internet "Near-Earth Object Confirmation Page". This draws attention to candidate earth-approaching objects in need of follow-up observations as soon as they have been reported to the MPC, following the derivation by Dr. Marsden of a particularly ingenious method for estimating the uncertainty of the prediction by automatically computing a series of orbits that represent just the first and the last observations. In 1998 he developed a certain amount of notoriety by suggesting that an object called 1997 XF11 could collide with the earth. He did this as a last-ditch effort to encourage the acquisition of further observations, including searches for possible data from several years earlier. The recognition of some observations from 1990 made it quite clear that there could be no collision with 1997 XF11 during the foreseeable future
