  3. A analítica kantiana do sublime em Friedrich Schiller

    Directory of Open Access Journals (Sweden)

    Artur Bispo dos Santos Neto

    2016-10-01

    Full Text Available O nosso texto tem como propósito apontar a articulação existente entre a estética kantiana, expressa na sua obra basilar Crítica da faculdade do juízo, e a reflexão estética constituída por Friedrich Schiller mediante a sua noção de sublime. Embora Schiller se inscreva sob o signo da influência da terceira Crítica, vamos mostrar na tessitura deste texto como consegue libertar-se da influência kantiana, ao recusar a centralidade do juízo de gosto na definição do belo e afirmar a beleza (puchritudo como liberdade no fenômeno. Schiller não se limita à investigação do sublime no âmbito da beleza livre (natureza, mas investiga-a especialmente no campo da beleza aderente. Embora o próprio Kant tenha atribuído ao gosto o significado de uma transição do prazer dos sentidos à disposição moral, será Schiller quem radicalizará o propósito de uma educação moral do homem pela mediação do sublime e do patético na arte.

  4. Debate on sublime in the end of 18th century: Burke, Kant, Schiller

    Directory of Open Access Journals (Sweden)

    Jeremić-Molnar Dragana

    2009-01-01

    Full Text Available In the article the authors are examining three positions within the 18th Century aesthetic discussion on the sublime - Edmund Burke's, Immanuel Kant's and Friedrich Schiller's. They are also trying to reconstruct the political backgrounds of each of this theoretical positions: old regime conservatism (Burke, republican liberalism (Schiller and romantic longing for the 'third way' (Kant. The most sophisticated and mature theory of sublime is found in Schiller's aesthetic works, especially in those following his disappointment in French Revolution, in which the relationship between sublime and paradoxes of historical violence is most thoroughly reflected.

    Kant's "Critique of Judgment," which was published in 1790, referred in detail to the affinity between beauty and morality. Schiller's writings from the 1790s dealing with aesthetics and ethics are intertwined, simultaneously, both with an affirmative reception of Kant's ideas and with critical attitudes against them. This applies to essays such…

    2013-12-01

    Full Text Available Pavao Ritter Vitezović was born in Senj on January 12, 1652 and died in Vienna on January 21, 1713. He attended elementary school in Senj and continued his education at a Jesuit high school in Zagreb, where his professor was Juraj Habdelić. After finishing the sixth grade in rhetoric, he quit school and went to Rome, where he met Johannes Lucius (Ivan Lučić. He was taught by cartographer Georg Matheus Vischer in Vienna. Vitezović spent the following two years in Bogenšperk (Wagensberg, Vagensperg, where Johann Weikhard Valvasor taught him surveying and copper-engraving. He prepared most templates for Croatian city views for Valvasor and engraved them in copper plates. He returned to Senj in 1679. As a city emissary, he travelled to the Viennese Parliament, where he advocated for Senj getting a royal charter and rights it had had for a long time. He participated in wars against Turks and became an officer for Nikola Erdödy. While he was staying as an emissary of Senj in Linz in 1684, he produced Odiljenje sigetsko and changed his German last name Ritter to Croatian Vitezović. He used to go outdoors and sketch cities and towers which he subsequently engraved in copper plates. This is how his copper-engravings were made which were incorporated in the album of Valvasor’s Topographia Ducatus Carnioliae modernae (Topography of Duchy of Carniola, as well as in Die Ehre des Herzogthums Crain (Glory of Duchy of Carniola in 1689. He participated in wars for liberation of Lika and Krbava and became the vice-prefect of Lika in 1691. He took over the Land Printing Office (Zemaljska tiskara at the session of the Croatian Parliament in Varaždin in 1694.

    In the chocolate factory Ritter Sport the heating systems were retrofitted in the last months. Two separated central heating plants were unified in a central block unit with cogeneration components. The piping system was decartelized and optimized. During the insulation of pipelines with elastomer high temperature materials high hygienical standards have to be kept. Furthermore the new lines have to be installed and insulated during running production because hot water supply shouldn't be interrupted.

  12. The aesthetic as a mediator of the moral and the politics in the history of reason: An approach to aesthetic theory of Friedrich Schiller

    Directory of Open Access Journals (Sweden)

    Ricard Casadesús

    2013-05-01

    Full Text Available Historic and rationalistic methods are for Schiller the only valid to truly understand the humanbeing. The great merit of Schiller was to have broken the subjectivity and the abstract nature of kantian thought and to have dared, under them, trying to catch by the thought the unity and the conciliation as constituent elements of the truth, and trying to artistically accomplish this conception. Schiller well-combines these three faculties of the spirit and offers an image of the whole man. These faculties, in Schiller, are converted in dynamic dialectic entities, those finally are combined in a higher harmony. So with this maybe built a state. Schiller comes to the conclusion that to solve the political question is necessary to passimmediately by the universe of the art because the way of liberty passes through the beauty.

  15. Hunger and love: Schiller and the origin of drive dualism in Freud's work.

    Science.gov (United States)

    Cotti, Patricia

    2007-02-01

    "The interpretation of dreams" was the first text in which Freud referred to the system of two drives (drive of self-preservation and the sexual drive). In order to understand how this question was at work in Freud's mind, one has to go back to 1898, when Freud began to write the third chapter of "The interpretation of dreams". One can then see, in contrast with Sulloway's assertions, how Freud was inspired by Schiller, whose shadow haunted his dreams between April and December 1898. The analysis of these dreams emphasizes how the references to Schiller's works and to the drive of self-preservation cover sexual impulses, in particular, those connected with the relationship to the father. The food drive or drive of self-preservation also enabled Freud to construct a heroic romance. He was thereby able to bury an internal criticism which was at odds with his persistence in describing the father as a seducer, and to conceal scenes in which he was defeated and sexually subdued by another boy.

  17. Don Carlos: Variations of Tragic from Schiller to Verdi

    Directory of Open Access Journals (Sweden)

    Fabio Vittorini

    2017-11-01

    Full Text Available In 1867 Giuseppe Verdi makes a grand opéra out of the dramatic poem Don Carlos, Infant von Spanien (1787 by Friedrich von Schiller. The workshop of Don Carlos lasts twenty years, from 1866 to 1886, when Verdi (reopens and closes several other workshops (Simon Boccanegra, La forza del destino, Aida, Requiem, Otello, creating a porous work in progress, whose analysis keeps giving us surprises. The libretto by Joseph Méry et Camille Du Locle, under the supervision of the composer, is a palimpsest where, under the official text referable to the common historical nucleus and its best known literary versions, some hidden or deleted heterogeneous texts appear, in a supranational, multilinguistic, intercultural and intertextual dimension, not always stirring along the road of a locatable derivation, of a voluntary imitation, but sometimes taking the shape of an unpredictable dissemination.

    The historical town of Weimar in Thuringia, the "green heart of Germany" was the sphere of Goethe and Schiller, the two most famous representatives of German literature's classic era. Not yet entirely as influential as those two cultural icons, the Signal Transduction Society (STS) has nevertheless in the last decade established within the walls of Weimar an annual interdisciplinary Meeting on "Signal Transduction - Receptors, Mediators and Genes", which is well recognized as a most attractive opportunity to exchange results and ideas in the field.The 12th STS Meeting was held from October 28 to 31 and provided a state-of-the-art overview of various areas of signal transduction research in which progress is fast and discussion lively. This report is intended to share with the readers of CCS some highlights of the Meeting Workshops devoted to specific aspects of signal transduction.

  19. History and Catastrophe: Tragedy and Reconciliation in Schiller and Hegel

    Directory of Open Access Journals (Sweden)

    Gabriel Aranzueque

    2013-11-01

    Full Text Available To what extent is it possible be reconciled with a tragic past? Could historical narration or dramatic performance help to get over the traumatic event indeed? Or do they just ascertain its constitutive contradictions, the split and the rift from a pain wich is impossible to sublimate? Is the mourning experience based on the recovery of a feeble balance between the opposite drives, emotions and feelings from the will? Or does it depend on the synthetic assimilation of that opposition into another way of life? This essay travels hand in hand with Schiller and Hegel across the space opened by those questions. It starts from the dissatisfaction generated in the young Hegel by his reading of Schiller’s Wallenstein and it analyzes his different conceptions of the ethic pathos, as well as his uneven perspective about the function of the chorus in the Attic tragedy

  20. Impulso formal e impulso sensible, algunas consideraciones sobre la educación estética desde Friedrich Schiller

    Directory of Open Access Journals (Sweden)

    Jorge Gregorio Posada Ramírez

    2016-07-01

    Full Text Available Este texto es un artículo de reflexión. Argumenta que la educación estética es un promisorio camino para promover uno de los más importantes objetivos de la educación: la formación integral. A partir de las Cartas sobre la educación estética del hombre, del filósofo y poeta Friedrich Schiller, se muestra que dos son los rasgos que pueden definir la vocación intelectual del hombre: el impulso formal y el impulso sensible. El primero, recoge la necesidad humana de racionalidad, esto es, la vocación a encontrar y construir abstracciones y regularidades del mundo, de fundirse en lo universal; el segundo, la inclinación de las personas a buscar emociones que aviven su sensibilidad y pasiones, de mantenerse como seres singulares. Descrito el impulso formal y el impulso sensible como las dos cualidades que holísticamente configuran las potencialidades intelectuales humanas, se muestra que la apreciación de lo bello, en términos de Schiller: la Forma viva, en tanto cultiva equilibradamente ambos ímpetus humanos, fomenta la educación integral en las personas.

  1. Alkylation of nitriles with gaseous carbenium ions. The ritter reaction in the dilute gas state

    International Nuclear Information System (INIS)

    Cacace, F.; Ciranni, G.; Giacomello, P.

    1982-01-01

    Radiolytically formed carbenium ions, such as sec-C 3 H 7 + , sec-C 4 H 9 + , and t-C 4 H 9 + , react in the gas phase with model aliphatic and aromatic nitriles yielding the corresponding nitrilium ions. The latter undergo efficient condensation with water that eventually leads to the formation of the corresponding N-alkylamides. The mechanism is analogous to the Ritter reaction in solution. The reactivity and selectivity of the gas-phase electrophilic attack on nitriles has been deduced from competition experiments under conditions that largely exclude the effects of solvation, ion pairing, etc., which complicate the interpretation of solution-chemistry measurements. 1 table

  5. A Sinner or a Saint: the image of Mary, Queen of Scots in the works of Friedrich Schiller, Juliusz Słowacki and Stefan Zweig

    Directory of Open Access Journals (Sweden)

    Melkov Andrey Sergeevich

    2017-04-01

    Full Text Available The artistic image of Mary, Queen of Scots in the works of F. Schiller, J. Słowacki and S. Zweig are researched in the article. The Queen’s life, character, inner world and psychological portrait appear on the pages of the classicists’ works in the context of the era she lived. The turbulent historical processes that took place in England and Scotland at the end of the Middle Ages and the beginning of the Early Modern Period led to the phenomenon of Mary Stuart’s personality. Obviously the creativity of the authors whose works were dedicated to Mary I of Scotland was influenced by the experience learned from the lessons of their time. It was reflected in the classicists’ analyses and description of the past. Romanticistsof the 19th century, F. Schiller and J. Słowacki, interpreted the personality of Mary Stuart in the sinner/saint dichotomy, but S. Zweig at the historic break in the 30s of the 20th century departed from the unilateralism of such an approach. In his romanced biography of Mary, Queen of Scots he tells about the rises and falls of his heroine. S. Zweig presents Mary I of Scotland as a wonderful, passionate and suffering woman, who even 400 years after her death inspires and excites peoples’ minds and hearts.

  6. Mind the Gap when Data Mining the Ritter-Kolb Cataclysmic Variable Catalogue

    Science.gov (United States)

    Sparks, Warren M.; Sion, Edward M.

    2017-01-01

    The cataclysmic variable (CV) binary consists of a white dwarf primary and a low-mass secondary which overflows its Roche lobe. The Ritter-Kolb catalogue (2003, A&A, 404, 301) is a collection (~1000) of CV binaries and related objects. We have mined this catalogue for CVs with unevolved secondaries whose mass ratio (secondary/primary) is known (~130). A plot of the secondary mass verses the log of the orbital period exhibits the well-known period gap at 2-3 hrs. In addition, this plot shows that the secondary masses just above the period gap are collectively much larger than those just below. The average of the first ten secondary masses above the period is 180% larger than the average below the gap.The disrupted magnetic braking hypothesis (Howell, Nelson, and Rappaport 2001, ApJ, 550, 897 [HNR]) predicts that when the secondary becomes fully convective, the magnetic braking, which has driven the secondary out of thermal equilibrium, stops. In adjusting to thermal equilibrium the secondary shrinks below its Roche lobe and no longer loses mass. The binary system ceases to appear as a CV until gravitational radiation loss brings the secondary back in contact with its Roche lobe. This scenario is at odds with the apparent secondary mass loss across the period gap. Either the secondary continues to lose mass while crossing the period gap or the secondary masses are miscalculated!Magnetic braking causes the secondary to expand or inflate larger than its single star counterpart. Any orbital parameter calculation which assumes a radius-mass relationship based on single main-sequence stars will overestimate the mass of the secondary. We can approximate this mass overestimation from calculations by HNR which take into account the thermal heating from magnetic braking. Using this approximation as a first-order correction to the secondary mass, we replot the deflated secondary mass versus the binary period. The deflated masses immediately above and below the period gap are

  11. Testing quantum contextuality. The problem of compatibility

    International Nuclear Information System (INIS)

    Szangolies, Jochen

    2015-01-01

    Jochen Szangolies contributes a novel way of dealing with the problem of the experimental testability of the Kochen-Specker theorem posed by realistic, that is, noisy, measurements. Such noise spoils perfect compatibility between successive measurements, which however is a necessary requirement to test the notion of contextuality in usual approaches. To overcome this difficulty, a new, extended notion of contextuality that reduces to Kochen-Specker contextuality in the limit of perfect measurement implementations is proposed by the author, together with a scheme to test this notion experimentally. Furthermore, the behaviour of these tests under realistic noise conditions is investigated.

    Full Text Available Sexually transmitted infections (STIs are among the most common public health problems worldwide. The study aimed to identify gynecological infectious etiology, based on the clinical complaint of the patient and later compare with the results released by the clinical laboratory, clinically analyzing external gynecological changes and clinical complaints of patients seen in primary care. This is a documentary, descriptive, and quantitative research, conducted in a primary care unit of the Sinop municipality in 2015. Women assisted by the Extension Project Team “Nursing care: A health promotion tool sexual and reproductive” participated in this work. The clinical examination data were collected in gynecological care and preventive examinations and recorded in a structured form. The number of preventive examinations in 2015 was 100 samples. The age of the women participating in the survey that stood out was 20 to 29 years old. Analyzing aspects of the cervix of patients who performed the Pap smear: 82 (82% were complete, 5 (5% showed some change, 6 (6% were friable, 5 (5% were not displayed having been surgically removed and 2 (2% were not displayed. According to this survey, of the 20 amendments in the laboratory results, 14 (70% examinations portrayed resemblance to the clinical description of the gynecological examination. The infectious agent of higher prevalence compared with the clinical description of abundant leucorrhea was Gardinerella vaginalis represented in 09 reports of cervical cytology. There was 68 (68% negative Schiller test and 8 (8% positive Schiller test and 24 (24% women, unfortunately, did not perform the test for lack of material during collection at the unit. It is concluded that investment in health education is necessary, with groups that address women's health, emphasizing the importance of prevention as well as the return of the woman to take the laboratory results and/or post-therapeutic assessment; promoting the

  1. Digital learning programs - competition for the classical microscope?

    Science.gov (United States)

    Schmidt, Peter

    2013-01-01

    The development of digital media has been impressive in recent years which is also among the reason for their increasing use in academic teaching. This is especially true for teaching Anatomy and Histology in the first two years in medical and dental curricula. Modern digital technologies allow for efficient, affordable and easily accessible distribution of histological images in high quality. Microscopy depends almost exclusively on such images. Since 20 years numerous digital teaching systems have been developed for this purpose. Respective developments have changed the ways students acquire knowledge and prepare for exams. Teaching staff should adapt lectures, seminars and labs accordingly. As a first step, a collection of high resolution digital microscopic slides was made available for students at the Friedrich-Schiller-University in Jena. The aim of the present study was to evaluate the importance of conventional light microscopy and related technologies in current and future medical and dental education aswell. A survey was done among 172 medical and dental students at the Friedrich-Schiller-University Jena. 51% of students use now frequently new digital media for learning histology in contrast to 5% in the year 2000 [1]. Digital media including Internet, CD- based learning combined with social networks successfully compete with classical light microscopy.

    Doctors today already frequently rely on positron emission tomography - PET for short - in cancer diagnostics. However, in order to use this method for other diseases, too, they need suitable tracer substances containing radioactive fluorine-18 - a challenge for Tobias Ritter and his team at the Max Planck Institut fuer Kohlenforschung in Muelheim an der Ruhr. The chemists are searching for ways to label diverse molecules with fluorine-18 and thus expand the range of possibilities for medical specialists.

    In his book, ‘Information Inequality’ (1996) Herbert Schiller argues that, by the mid-1990s, information had become another commodity of the newly global political system of market capitalism and this development was instrumental in widening the gap between the poorest and the best off in American society. This paper reviews Schiller’s claims and examines its bearing on society in the decade and half since the publication of his book.

    Full Text Available The TMSOTf-mediated synthesis of β-configured spirocyclic 2-substituted-2-oxazoline ribosides was achieved using a “Ritter-like” reaction in toluene through nucleophilic addition of electron-rich nitriles to the oxacarbenium ion intermediate of 1,2;3,4-di-O-isopropylidene-β-D-psicofuranose derivatives with concomitant intramolecular trapping of the C2 hydroxymethyl group on the electrophilic nitrilium carbon. These carbohydrate-derived spirooxazolines are stable and were obtained in good yield with high stereoselectivity due to the conformational rigidity imparted by the 3,4-isopropylidene group.

Diesem ‚Paradigmenwechsel‘ entspricht der vorliegende Band, in dem neue Fragestellungen an das an Raumschilderungen so reiche Werk Droste-Hülshoffs herangetragen werden. Neben einer thematischen Einführung und einem theoretischen Überblick zu Raumkonzeptionen sind zwölf Beiträge versammelt, die sich u. a. mit Fragen nach einer Poetologie des Raums, nach den Raumkonzepten sowie deren Funktionen im Text beschäftigen. Die Relevanz dieser Fragestellungen für die Droste-Forschung wird überzeugend nachgewiesen. Zugleich kommt aber die theoretische Reflexion etwas zu kurz. Wichtigste und zum Teil einzige Referenz ist Michel Foucaults „Heterotopie“-Begriff – trotz oder wegen mancher Inkonsistenzen dieses Konzepts.Since the so-called spatial turn, space has become a central category also for literary and cultural studies. This ‘paradigm shift’ corresponds to the volume at hand, which asks new questions of the work of Droste-Hülshoff, itself rich in spatial descriptions. The volume contains a thematic introduction and a theoretical overview of spatial conceptions as well as twelve contributions approaching such questions as the poetology of space, spatial conceptions, and their functions in text. The volume convincingly proves the relevance of these questions for Droste research. At the same time, however, it does not adequately discuss theoretical reflections. The most important and often sole reference is Michel Foucault’s term “heterotopology,” despite, or perhaps because of, this concept’s inconsistencies.

    Full Text Available Cette étude vise à étudier l’unique traduction anglaise de l’opéra de Donizetti Maria Stuarda (1835, réalisée pour l’English National Opera en 1973. Dans le cadre d’une réflexion sur la « réécriture du patrimoine anglophone », ce travail cherche à montrer comment le recours à la traduction dans un contexte culturel particulier, la Grande-Bretagne des années 1970 et 1980, modifie considérablement les enjeux historiques et politiques qui ressortent de l’œuvre- source. Ainsi, si l’opéra de Donizetti propose une lecture « revisitée » de l’histoire, par le biais notamment l’œuvre de Schiller, le processus de la « traduction » permet lui aussi de recadrer et de recontextualiser le propos. On s’attachera ainsi à examiner le traitement des aspects historiques et religieux de l’opéra de Donizetti. Enfin, on pourra également analyser les modifications faites sur le plan musical, ainsi que sur celui de la distribution vocale. Loin d’être innocent, le choix assez curieux de Janet Baker – valeur « nationale » s’il en est – pour incarner l’infortunée reine Stuart n’était-il pas à lui-même destiné à émousser, ou à recadrer, les enjeux essentiels de l’ouvrage de Donizetti ?This article is about the only English singing-translation of Donizetti’s Maria Stuarda, as performed by the ENO in the 1970s and 80s. It aims at showing how the translated text considerably modifies the historical and political issues of the original version, the English text being a form of correction of the work of Schiller and Donizetti’s librettist, Giuseppe Bardari. If Donizetti’s work already offers, via Schiller, a somewhat revised version of History, the translation and recontextualisation of the opera pushes the transformation a little bit further. The paper thus examines some of the religious and historical aspects of such a cultural transfer, but also some of the musical modifications brought to

    Results on hadron production in π + p and K + p interactions at 250 GeV/c are presented from the experiment NA22 at the CERN SPS. With the present statistics we find: scaling in the fragmentation regions for both charged and neutral pions; a reasonable description of the K + p→π 0 /π + p→π 0 ratio by both the LUND M.C. and a DTU M.C. (Ranft and Ritter), agreement with these Monte Carlo's for the K + /π + population percentages in the forward hemisphere; no agreement for the seagull with the LUND M.C. and strong disagreement with the DTU M.C

    Foster, Brendan; Merali, Zeeya

    2018-01-01

    This collection of prize-winning essays addresses the controversial question of how meaning and goals can emerge in a physical world governed by mathematical laws. What are the prerequisites for a system to have goals? What makes a physical process into a signal? Does eliminating the homunculus solve the problem? The three winning essays, by Larissa Albantakis, Carlo Rovelli and Jochen Szangolies tackle exactly these challenges, while many other aspects (agency, the role of the observer, causality versus teleology, ghosts in the machine etc.) put in an appearance in the other award winning contributions. These seventeen imaginative, stimulating and often entertaining essays are enhanced versions of the prize-winning entries to the FQXi essay competition in 2017. The Foundational Questions Institute, FQXi, catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlik...

    Palanco, Marta Espina; Catak, Darmin; Marie, Rodolphe

    2016-01-01

    An optical two-beam trap, composed from two counter propagating laser beams, is an interesting setup due to the ability of the system to trap, hold, and stretch soft biological objects like vesicles or single cells. Because of this functionality, the system was also named "the optical stretcher...... wish to trap, thereby preventing too many cells to flow below the line of focus of the two counter propagating laser beams that are positioned perpendicular to the direction of flow of the cells. Results will be compared to that from other designs from previous work in the group......." by Jochen Guck, Josep Käs and co-workers some 15 years ago. In a favorable setup, the two opposing laser beams meet with equal intensities in the middle of a fluidic channel in which cells may flow past, be trapped, stretched, and allowed to move on, giving the promise of a high throughput device.

    The addition of nitriles of varying nucleophilicity to isocamphanol and exo-1,5,5-trimethyl-bicyclo[2.2.1]heptan-2-ol (isofenchol) was investigated. The authors examined the effect of the reaction conditions on the yield and structure of the target products of the reaction: N-substituted amides. As a result of the study, it was shown that in the reaction with chloroacetonitrile, propionitrile, methoxypropionitrile, isovaleronitrile, and phenylacetonitrile under the conditions of the Ritter reaction, isocamphanol is transformed into the corresponding substituted exo-N-acyl-1,7,7-trimethylbicyclo[2.2.1]hept-2-ylamines, as in the reaction with aceto- and benzonitriles, due to 2,6-hydride displacement accompanied by Wagner-Meerwein rearrangement. The structures of these amides were demonstrated by PMR spectroscopy

    Full Text Available The microbial contamination in food packaging has been a major concern that has paved the way to search for novel, natural anti-microbial agents, such as modified α-mangostin. In the present study, twelve synthetic analogs were obtained through semi-synthetic modification of α-mangostin by Ritter reaction, reduction by palladium-carbon (Pd-C, alkylation, and acetylation. The evaluation of the anti-microbial potential of the synthetic analogs showed higher bactericidal activity than the parent molecule. The anti-microbial studies proved that I E showed high anti-bacterial activity whereas I I showed the highest anti-fungal activity. Due to their microbicidal potential, modified α-mangostin derivatives could be utilized as active anti-microbial agents in materials for the biomedical and food industry.

    Full Text Available [english] The development of digital media has been impressive in recent years which is also among the reason for their increasing use in academic teaching.This is especially true for teaching Anatomy and Histology in the first two years in medical and dental curricula. Modern digital technologies allow for efficient, affordable and easily accessible distribution of histological images in high quality. Microscopy depends almost exclusively on such images. Since 20 years numerous digital teaching systems have been developed for this purpose. Respective developments have changed the ways students acquire knowledge and prepare for exams. Teaching staff should adapt lectures, seminars and labs accordingly. As a first step, a collection of high resolution digital microscopic slides was made available for students at the Friedrich-Schiller-University in Jena. The aim of the present study was to evaluate the importance of conventional light microscopy and related technologies in current and future medical and dental education aswell. A survey was done among 172 medical and dental students at the Friedrich-Schiller-University Jena. 51% of students use now frequently new digital media for learning histology in contrast to 5% in the year 2000 . Digital media including Internet, CD- based learning combined with social networks successfully compete with classical light microscopy.[german] Die Entwicklung digitaler Medien wuchs in jüngster Zeit beträchtlich an, was mitunter als Ursache für deren wachsende Nutzung in der universitären Lehre anzusehen ist. Zutreffend ist dies insbesondere auch im Bereich der Anatomie und Histologie, welche Bestandteile des Studiums für Ärzte und Zahnärzte in den ersten zwei Studienjahren darstellen. Moderne digitale Technologien erlauben es eine leistungsfähige, bezahlbare und begreifbare Verbreitung histologischer Bilder in hoher Qualität zu gewährleisten.

    We use the operational Russian COSMO-Ru weather forecast model (Ritter and and Geleyn, 1991) with different aerosol input data for the evaluation of radiative and temperature effects of aerosol in different atmospheric conditions. Various aerosol datasets were utilized including Tegen climatology (Tegen et al., 1997), updated Macv2 climatology (Kinne et al., 2013), Tanre climatology (Tanre et al., 1984) as well as the MACC data (Morcrette et al., 2009). For clear sky conditions we compare the radiative effects from the COSMO-Ru model over Moscow (55.7N, 37.5E) and Lindenberg/Falkenberg sites (52.2N, 14.1E) with the results obtained using long-term aerosol measurements. Additional tests of the COSMO RT code were performed against (FC05)-SW model (Tarasova T.A. and Fomin B.A., 2007). The overestimation of about 5-8% of COSMO RT code was obtained. The study of aerosol effect on temperature at 2 meters has revealed the sensitivity of about 0.7-1.1 degree C per 100 W/m2 change in shortwave net radiation due to aerosol variations. We also discuss the radiative impact of urban aerosol properties according to the long-term AERONET measurements in Moscow and Moscow suburb as well as long-term aerosol trends over Moscow from the measurements and Macv2 dataset.

  4. Environmental controls for the precipitation of different fibrous calcite cement fabrics

    Ritter, Ann-Christine; Wiethoff, Felix; Neuser, Rolf D.; Richter, Detlev K.; Immenhauser, Adrian

    2016-04-01

    Abiogenic calcite cements are widely used as climate archives. They can yield information on environmental change and climate dynamics at the time when the sediment was lithified in a (marine) diagenetic environment. Radiaxial-fibrous (RFC) and fascicular-optic fibrous (FOFC) calcite cements are two very common and similar pore-filling cement fabrics in Palaeozoic and Mesozoic carbonate rocks (Richter et al., 2011) and in Holocene Mg-calcitic speleothems (Richter et al., 2015). Both fabrics are characterised by distinct crystallographic properties. Current research has shown that these fabrics are often underexplored and that a careful combination of conservative and innovative proxies allows for a better applicability of these carbonate archives to paleoenvironmental reconstructions (Ritter et al., 2015). A main uncertainty in this context is that it is still poorly understood which parameters lead to the formation of either RFC or FOFC and if differential crystallographic parameters affect proxy data from these fabrics. This study aims at a better understanding of the environmental factors that may control either RFC or FOFC precipitation. Therefore, suitable samples (a stalagmite and a Triassic marine cement succession), each with clearly differentiable layers of RFC and FOFC, were identified and analysed in high detail using a multi-proxy approach. Detailed thin section and cathodoluminescence analysis of the samples allowed for a precise identification of layers consisting solely of either RFC or FOFC. Isotopic (δ13C, δ18O) as well as trace elemental compositions have been determined and the comparison of data obtained from these different carbonate archives sheds light on changes in environmental parameters during RFC or FOFC precipitation.

    Full Text Available Recent years have seen a renewed interest in the traditional pre-Keynesian quantity theory. This paper is concerned with the contention that - in the formal development of this theory in the past - a change in the quantity of money expends itself solely in influencing the price level, but not the volume of output even in the short run. This contention about the nature of the theory seems to be common both to its critics and to at least one of its modern-day adherents. The author examines the writings of Irving Fisher, the Chicago school, the Cambridge economists, and other quantity theorists to determine the validity of the interpretations put forth by Lawrence Ritter and Milton Friedman.JEL: E31, E40, E51

    This paper will report on the past year's work on the development of the microcontroller design for the second Purdue University small self-contained payload. A first report on this effort was given at last year's conference by Ritter (1985). At that time, the project was still at the conceptual stage. Now a specific design has been set, prototyping has begun, and layout of the two-sided circuit board using CAD-techniques is nearing completion. A redesign of the overall concept of the circuit board was done to take advantage of the facilities available to students. An additional controller has been added to take large quantities of data concerning the shuttle environment during takeoff. The importance of setting a design time-line is discussed along with the electrical design considerations given to the controllers.

Therefore, visualizing drugs or micro- and nanoparticulate delivery systems to analyze their distribution and effects in biofilms requires a third fluorescent dye that does not interfere with the properties of the live/dead markers. The present study establishes and evaluates a model for tracking polymeric particles in fluorescently stained biological material. To this end, poly(D,L-lactide-co-glycolide (PLGA-based micro- and nanoparticles were used as well-established model systems, which, because of their favorable safety profiles, are expected to play important future roles with regard to drug delivery via inhalation. PLGA was covalently and stably labeled with 7-amino-4-methyl-3-coumarinylacetic acid (AMCA, after which blue fluorescent poly(ethylene glycol-block-PLGA (PEG-PLGA particles were prepared using a mixture of fluorescent AMCA-PLGA and PEG-PLGA. Because chitosan is known to reduce negative surface charge, blue fluorescent PEG-PLGA-particles with chitosan were also prepared. These micro- and nanoparticles were physicochemically characterized and could be clearly distinguished from live/dead stained bacteria in biofilms using confocal laser scanning microscopy.

    Full Text Available RESUMEN: En este trabajo se reproduce y comenta un informe remitido por Juan Roura-Parella, discípulo predilecto de Joaquín Xirau, desde Berlín en febrero de 1932. Frente a la atracción ejercida en España por el positivismo, Roura-Parella —que estudió Pedagogía en Alemania durante dos años (1930-1932— plantea la alternativa de la pedagogía de las ciencias del espíritu (Geisteswissenschaftliche Pädagogik que, siguiendo la huella de Dilthey, defendía Spranger en sintonía con la escuela del trabajo (Arbeitsbildung de Kerschensteiner. De alguna manera, esta pedagogía que combinaba la especialización profesional y los valores objetivos de la cultura deseaba vivificar —de acuerdo con la tradición formativa del idealismo de la libertad (Kant, Schiller, Goethe— una cultura que, después de la Primera Guerra Mundial, había entrado en una profunda crisis económica, política, social y, sobre todo, espiritual, situación que no era extraña en aquella incipiente España de la Segunda República (1931-1939. ABSTRACT: This work includes a reproduction of and comment on a report sent from Berlin by Juan Roura-Parella, favourite disciple of Joaquín Xirau, in February 1932. Faced with the appeal of positivism, Roura-Parella —who studied Pedagogy in Germany for two years (1930-1932— put forward the alternative of spiritual scientific pedagogy (Geisteswissenschaftliche Pädagogik which, in the footsteps of Dilthey, defended Spranger and befitted Kerschensteiner’s work school (Arbeitsbildung.

    Since the mid-1980`s, heavy metal characterisation was carried out on sediments of selected sections of the river Saale and methodical work was done on the analysis of flowing water at the Friedrich Schiller University at Jena. However, there was no comprehensive and current information about the state of contamination along the whole course of the river before. The most important aim was therefore the first and current stocktaking of this extent of contamination of the water, sediment and suspended matter of the Saale. The basis of these considerations was formed by about 15,000 determined features in water samples and more than 1,000 examinations of suspended matter and 4,600 examinations of sediment. In the characterisation of contamination of flowing watercourses, it was generally usual to evaluate the change of individual features according to geographic or time aspects. The application of methods of multi-variate statistics makes it possible to identify anthropogenic and geogenic sources and to discover latent connections. A comprehensive evaluation of the actual contamination situation is possible in this way. (orig./SR) [Deutsch] Seit Mitte der achtziger Jahre werden an der Friedrich-Schiller-Universitaet Jena Schwermetallcharakterisierungen an Sedimenten ausgewaehlter Flussabschnitte der Saale sowie methodische Arbeiten zur Fliessgewaesseranalytik durchgefuehrt. Umfassende und aktuelle Informationen ueber den Belastungszustand entlang des gesamten Flussablaufes gab es jedoch bisher nicht. Wichtigstes Ziel war deshalb eine in diesem Umfang erstmalige und aktuelle Bestandsaufnahme zur Belastung von Wasser, Sediment und Schwebstoffe der Saale. Die Grundlage dieser Betrachtungen bilden ca. 15.000 bestimmte Merkmale in Wasserproben und mehr als 1.000 Schwebstoff- und 4.600 Sedimentuntersuchungen. Bei der Belastungscharakterisierung von Fliessgewaessern ist es derzeit allgemein ueblich, die Aenderung einzelner Merkmale nach geographischen oder zeitlichen

    Great friction currently exists between family planning advocates and institutions opposed to contraception or abortion on religious grounds as the time draws near to convene the 1994 UN International Conference on Population and Development. A rift is also open between those who understand rapid population growth as a symptom of deep social inequities and those who see it only as a disease unto itself. The Human Development Report 1994 notes that human development like women's education is often the most powerful contraceptive, while the Vatican complains that the conference is about cultural imperialism. Planned Parenthood, however, counters that the Vatican has its head in the sand with regard to modern life and lifestyles. Other short comments are listed by the Executive Coordinator of the conference, the founder of Scientific American, and the Schiller Institute.

    2013-01-01

    Investigating ways of integrating material performance as a design parameter, four presented projects employ the ability to model force and flow to parameterize and calculate material properties. According to Beylerian and Ritter material performance is today regarded as one of the richest sources...... of innovation. By understanding materials not as static or inanimate, but as engaged by complex behaviours and performances, a new dimension of design potentials can be unleashed. The notion of a new digital-material practice, in which the design and detailing of materials are directly linked to the design...... and detailing of buildings, provides the framework for an emerging field of architectural research. Aiming to innovate structural thinking and create better and more sustainable material usage, these new material practices rely on the ability to compute complex inter-scalar dependencies and link these directly...

    Full Text Available Algonquian languages are famous for their animacy-based grammatical properties—an animacy based noun classification system and direct/inverse system which gives rise to animacy hierarchy effects in the determination of verb agreement. In this paper I provide new evidence for the proposal that the distinctive properties of these languages is due to the use of participant-based features, rather than spatio-temporal ones, for both nominal and verbal functional categories (Ritter & Wiltschko 2009, 2014. Building on Wiltschko (2012, I develop a formal treatment of the Blackfoot aspectual system that assumes a category Inner Aspect (cf. MacDonald 2008, Travis 1991, 2010. Focusing on lexical aspect in Blackfoot, I demonstrate that the classification of both nouns (Seinsarten and verbs (Aktionsarten is based on animacy, rather than boundedness, resulting in a strikingly different aspectual system for both categories.

    2011-07-01

    Full Text Available The conceptual basis which would be later developed by the artistic avant-gardes was settled by German Romantic and Idealist thought, whose utopian dimension could be easily recognized in The oldest systemprogram of German Idealism (1796, a text which provided Idealist thought with the claim of a new rationality or a mythology of reason in Hegel, an intellectual intuition in Schelling and the Humanity in Schiller. Although this emancipation project developed later by the avant-garde has lost its credibility for us, we still have to investigate to what extent today’s art can maintain a social function. This article point out certain idealist concepts in light of a philosophy of art modeled along lines sketched out in Kant’s Critique of Judgement and that have contributed to the history of the “advanced” art.

    This article reports an open discussion that took place during the Keenan Symposium "Meeting the Entropy Challenge" (held in Cambridge, Massachusetts, on October 4, 2007) following the short presentations—each reported as a separate article in the present volume—by Seth Lloyd, Owen Maroney, Silviu Guiasu, Ping Ao, Jochen Gemmer, Bernard Guy, Gian Paolo Beretta, Speranta Gheorghiu-Svirschevski, and Dorion Sagan. All panelists and the audience were asked to address the following questions • Why is the second law true? Is it an inviolable law of nature? If not, is it possible to develop a perpetual motion machine of the second kind? • Are second law limitations objective or subjective, real or apparent, due to the nature of physical states or the representation and manipulation of information? Is entropy a physical property in the same sense as energy is universally understood to be an intrinsic property of matter? • Does the second law conflict with quantum mechanics? Are the differences between mechanical and thermodynamic descriptions of physical phenomena reconcilable? Does the reversible law of motion of hamiltonian mechanics and quantum mechanics conflict with the empirical observation of irreversible phenomena?

    With a 1-m telescope on the University of Toledo (OH) main campus, we have initiated a grad student-undergraduate partnership to help teach the undergraduates observational methods and introduce them to research through peer mentorship. For the last 3 years, we have trained up to 21 undergraduates (primarily physics/astronomy majors) in a given academic semester, ranging from freshman to seniors. Various projects are currently being conducted by undergraduate students with guidance from graduate student mentors, including constructing three-color images, observations of transiting exoplanets, and determination of binary star orbits from echelle spectra. This academic year we initiated a large group research project to help students learn about the databases, journal repositories, and online observing tools astronomers use for day-to-day research. We discuss early inclusion in observational astronomy and research of these students and the impact it has on departmental retention, undergraduate involvement, and academic success.

    Full Text Available The Marbach Records Hall, used for the study of modem German literature, is connected to the Schiller Museum by a low terrace. The shape of the museum, similar to a castle, creates a relationship of subordination with all the surrounding structures. In this case, that subordination was the main factor conditioning the architectural design and heights of the new building. The building consists of several divided modules, in terrace form, arranged around the premises to be used. These modules are in turn made up of reading rooms and card catalogues. Next to the main entrance there is a lecture hall and a small coffee shop. With the exception of the lecture hall, the entire structure has a basement below it. The storage rooms and book and magazine storage spaces have been distributed on two floors underneath the card catalogue areas. Exposed concrete was used for the entire construction, both for the structure as well as for the interior and exterior surfaces, contrasting with the dark bronze colored aluminum bay windows.El Archivo Marbach, destinado al estudio de la literatura alemana moderna, está comunicado a través de una terraza baja con el Museo Schiller, cuya forma, semejante a un castillo, crea una relación de subordinación a todas las construcciones de alrededor.

    [7,8,9]. Furthermore, in order to learn more about the chemistry in interstellar clouds, astrochemists can benefit greatly from direct measurements on cold reactions in laboratories [9]. Working with MgH+ molecular ions in a linear Paul trap, we routinely cool their translational degree of freedom...... by sympathetic cooling with Doppler laser cooled Mg+ ions. Giving the time for the molecules to equilibrate internally to the room temperature blackbody radiation, the vibrational degree of freedom will freeze out, leaving only the rotational degree of freedom to be cooled. We report here on the implementation...... results imply that, through this technique, cold molecular-ion experiments can now be carried out at cryogenic temperatures in room-temperature set-ups.

    2012-11-01

    This article tries to link the present lack of theoretical discussion within German Social Psychiatry with a loss of phenomenological and anthropological thought. The so-called Phenomenological Psychiatry used to play a very important role in German psychiatry during the 50 ies until the 70 ies and had strong influences on the first reformers of German psychiatry, such as Walter Ritter von Baeyer, Heinz Häfner, Caspar Kulenkampff, Karl Peter Kisker and Erich Wulff. Their reforms were not only founded by a social criticism put forth by theories such as marxism (Basaglia, Wulff) or structuralism (Foucault) but also by a concrete notion of what it is like to suffer from mental illness and what kind of needs are linked to such suffering. This very notion was given by the phenomenological approach. Finally the article tries to give reasons for today's reciprocal loss of connection of the phenomenological and the socio-psychiatric school. © Georg Thieme Verlag KG Stuttgart · New York.

    The implant assisted magnetic targeted drug delivery system of Aviles, Ebner and Ritter is considered both experimentally (in vitro) and theoretically. The results of a 2D mathematical model are compared with 3D experimental results for a magnetizable wire stent. In this experiment a ferromagnetic, coiled wire stent is implanted to aid collection of particles which consist of single domain magnetic nanoparticles (radius ∼10nm). In order to model the agglomeration of particles known to occur in this system, the magnetic dipole-dipole and hydrodynamic interactions for multiple particles are included. Simulations based on this mathematical model were performed using open source C++ code. Different initial positions are considered and the system performance is assessed in terms of collection efficiency. The results of this model show closer agreement with the measured in vitro experimental results and with the literature. The implications in nanotechnology and nanomedicine are based on the prediction of the particle efficiency, in conjunction with the magnetizable stent, for targeted drug delivery.

Since the reference values of breathing rate provided by the International Commission on Radiological Protection (ICRP) are based on the physiology of Caucasian, they are not necessarily appropriate for internal dosimetry for Korean. In this study, we assessed breathing rate of Korean by measuring the forced vital capacity (FVC), the forced expiratory volume in second (FEV1) and the minute ventilation(MV). Measurements were made using SP-1 spirometry unit (Schiller AG. 1998) for 1474 adult Koreans whose heights and weights are in the range of one standard deviation from the mean values. The total liters of air breathed for working and resting were evaluated after the ICRP approach. We also considered smoking and ailment in the lungs. The resulting breathing rate appears to be 2.3x10 4 L/day which well agrees with the value given in ICRP 23

    We show that the quantum Hamilton-Jacobi equation can be written in the classical form with the spatial derivative ∂ q replaced by ∂ q with dq = dq/√1-β 2 (q), where β 2 (q) is strictly related to the quantum potential. This can be seen as the opposite of the problem of finding the wave function representation of classical mechanics as formulated by Schiller and Rosen. The structure of the above open-quotes quantum transformationclose quotes, related to the recently formulated equivalence principle, indicates that the potential deforms space geometry. In particular, a result by Flanders implies that both W(q) = V(q) - E and the quantum potential Q are proportional to the curvatures κ W and κ Q which arise as natural invariants in an equivalence problem for curves in the projective line. In this formulation the Schroedinger equation takes the geometrical form (∂ q 2 + κ W )ψ = 0

    Several studies show that there is a connection between religion and prosociality (e.g., Saroglou, 2013). To investigate whether there is a causal relationship between these two variables, a growing number of scholars employed priming religious concepts and measure its influence on prosocial behavior (e.g., Pichon, Boccato, & Saroglou, 2007). In the recent development of religious priming, Ritter and Preston (2013) argued that different primes (agent prime, spiritual/abstract prime, and institutional prime) may also have varying influence on prosocial behavior specifically helping an ingroup or an outgroup target. With this in mind, a 2 (social categorization of the target of help) by 3 (agent prime, institutional prime, spiritual prime) experiment was conducted to directly investigate this hypothesis. Results suggest that priming religious concepts especially the spiritual prime can increase prosocial behaviors. However, no significant effect was found on the social categorization which implies that Filipino participants elicit prosocial behavior regardless of the social categorization (be it ingroup or outgroup) of the target of help. The present study's findings contribute to further the literature on religious priming and its influence on prosocial behavior.

  20. Observing a Burst with Sunglasses

    Unique Five-Week VLT Study of the Polarisation of a Gamma-Ray Burst Afterglow "Gamma-ray bursts (GRBs)" are certainly amongst the most dramatic events known in astrophysics. These short flashes of energetic gamma-rays, first detected in the late 1960's by military satellites, last from less than one second to several minutes. GRBs have been found to be situated at extremely large ("cosmological") distances. The energy released in a few seconds during such an event is larger than that of the Sun during its entire lifetime of more than 10,000 million years. The GRBs are indeed the most powerful events since the Big Bang known in the Universe, cf. ESO PR 08/99 and ESO PR 20/00. During the past years circumstantial evidence has mounted that GRBs signal the collapse of extremely massive stars, the so-called hypernovae. This was finally demonstrated some months ago when astronomers, using the FORS instrument on ESO's Very Large Telescope (VLT), documented in unprecedented detail the changes in the spectrum of the light source ("the optical afterglow") of the gamma-ray burst GRB 030329 (cf. ESO PR 16/03). A conclusive and direct link between cosmological gamma-ray bursts and explosions of very massive stars was provided on this occasion. Gamma-Ray Burst GRB 030329 was discovered on March 29, 2003 by NASA's High Energy Transient Explorer spacecraft. Follow-up observations with the UVES spectrograph at the 8.2-m VLT KUEYEN telescope at the Paranal Observatory (Chile) showed the burst to have a redshift of 0.1685 [1]. This corresponds to a distance of about 2,650 million light-years, making GRB 030329 the second-nearest long-duration GRB ever detected. The proximity of GRB 030329 resulted in very bright afterglow emission, permitting the most extensive follow-up observations of any afterglow to date. A team of astronomers [2] led by Jochen Greiner of the Max-Planck-Institut für extraterrestrische Physik (Germany) decided to make use of this unique opportunity to study the

    This remarkable photograph (which spans only 10 m across; click for a full view) reveals what happens when you form dust grains in a laboratory under conditions similar to those of interstellar space. The cosmic life cycle of dust grains is not well understood we know that in the interstellar medium (ISM), dust is destroyed at a higher rate than it is produced by stellar sources. Since the amount of dust in the ISM stays constant, however, there must be additional sources of dust production besides stars. A team of scientists led by Daniele Fulvio (Pontifical Catholic University of Rio de Janeiro and the Max Planck Institute for Astronomy at the Friedrich Schiller University Jena) have now studied formation mechanisms of dust grains in the lab by mimicking low-temperature ISM conditions and exploring how, under these conditions, carbonaceous materials condense from gas phase to form dust grains.

Jorge Semprún gave three keynote speeches titled «Kant and the Maquis’ rucksack», «The radical evil and the Buchenwald latrines» and «Literature and memory of the evil: from Sartre to Paul Ricoeur», all of them grouped under the generic denomination Memory of Evil. The thread running through the three speeches was Semprún’s experience as a political deportee at Buchenwald concentration camp, so close to the Weimar camp of Schiller and Goethe. There, he could experience the radical evil, but also the brotherhood through the antifascist resistance groups who coordinated the various clandestine political groups at the camp. This experience helped him review some of the philosophical readings he had done as a philosphy student at the Sorbonne, as well as those readings he took an interest in following the end of the war. In this way, Semprún went over various authors (Immanuel Kant, André Malraux, Edmund Husserl, Jacques Maritain, Martin Heidegger, Karl Marx, Hannah Arendt, Jean Paul Sartre, Paul Ricoeur or Primo Levi arguing their relationship with the issue of Evil.

    En mayo de 2003 se celebró la duodécima edición de las «Conferencias Aranguren».

    Full Text Available Introduction: Decades of research support the theory that when there are sports competitions the question of what to eat and drink in order to enhance sport performance. Nutrition is one of the most important factors in achieving top performance athletes. According to most studies conducted in the world's top athletes receive information from their coaches when it comes to sports nutrition, especially of the coaches involved in fitness training. (Burns, Schiller, Merrick & Wolf, 2004.The aim of this study was to determine the knowledge of sports nutrition in sports coaching. Mthods: The sample was composed of 30 licensed coaches from Montenegro (football, handball, basketball, volleyball, athletics and tennis. Knowledge of sports nutrition was tested by means of a standardized questionnaire. The questionnaire was designed to determine the knowledge manager on sports nutrition, the ingredients that are necessary in order to provide a sufficient amount of energy to training and competition, the dietary supplements, meal prior to the competition as well as dehydration and rehydration during training and competition. The survey was anonymous. The data were analyzed by statistical methods, using the statistical software STATISTICA for WINDOWS. Results: According to the results as a whole, it can be concluded that the trainer's knowledge of sports nutrition at a satisfactory level. Out of 600 responses was achieved 469 correct answers, or 78.1%.

    The effects of perceived stress (PS) on the relationship between adaptive and maladaptive forms of perfectionism and burnout were examined. Smith's (1986)stress appraisal model and Kelley, Eklund, and Ritter-Taylor's (1999) model of coach burnout were used to test two models of burnout in a sample of college coaches (N=177). The results indicated that there is an indirect effect of self-evaluative perfectionism (i.e., maladaptive form of perfectionism) on burnout through PS as well as a significant direct link to burnout, accounting for 56% of its variance. In contrast, conscientious perfectionism (CP) (i.e., adaptive perfectionism) did not directly impact burnout, nor was there an indirect effect through PS. Based on Lazarus's (1999) ideas about stress appraisal, the results suggested that maladaptive forms of perfectionism resulted in more threatening perceptions of stress, thus, potentially leading to the experience of burnout. However, adaptive forms of perfectionism did not seem to result in increased appraisals of stress or result in burnout. The results did indicate a significant correlation between the two forms of perfectionism, which may explain why CP did not significantly impact PS or burnout.

There were talks on the first morning by Hans-Georg Ritter and Karl-Heinz Kampert on the Plastic Ball at Berkeley, there will be a talk next week by Rudi Schmidt on the Plastic Ball at CERN, and many other speakers have mentioned Plastic Ball results. The young students may think that when the new field of relativistic heavy ion physics opened up, an ideal detector was designed and built, data immediately analyzed, and results produced. The theme of my talk is to show that this is incorrect. The experiments proceeded in logical stages, one building upon the other, increasing in complexity and sophistication. The analysis techniques and the theory developed along with the experiments. If the more senior people in the audience easily remember this history of the development of the relativistic heavy ion field, they may spend their time during this talk thinking about what is happening now and what will happen in the future in the ultrarelativistic heavy ion field, where I believe history is repeating itself. 18 refs., 18 figs

    Density functional theory calculations have been performed to investigate the use of CO as a probe molecule for the determination of the structure and composition of Au, Ag and AuAg nanoparticles. For very small nanoclusters (x = 1 - 5), the CO vibrational frequencies can be directly correlated to CO adsorption strength, whereas larger 147-atom nanoparticles show a strong energetic preference for CO adsorption at a vertex position but the highest wavenumbers are for the bridge positions. We also studied CO adsorption on Au and Ag (100) and (111) surfaces, for a 1 monolayer coverage, which proves to be energetically favourable on atop only and bridge positions for Au (100) and atop for Ag (100); vibrational frequencies of the CO molecules red-shift to lower wavenumbers as a result of increased metal coordination. We conclude that CO vibrational frequencies cannot be solely relied upon in order to obtain accurate compositional analysis, but we do propose that elemental rearrangement in the core@shell nanoclusters, from Ag@Au (or Au@Ag) to an alloy, would result in a shift in the CO vibrational frequencies that indicate changes in the surface composition.

A principal element of hypoxia-awareness training is the intentional evocation of hypoxia symptoms during specific training sessions within a safe and controlled environment. Repetitive training should enable pilots to learn and recognize their personal hypoxia symptoms. A time span of 3–6 years is generally considered suitable to refresh knowledge of the more subtle and early symptoms especially. Currently, there are two different technical approaches available to induce hypoxia during training: hypobaric chamber training and reduced-oxygen breathing devices. Hypoxia training for aircrew is extremely important and effective, and the hypoxia symptoms should be emphasized clearly to aircrews. The use of tight-fitting masks, leak checks, and equipment checks should be taught to all aircrew and reinforced regularly. It is noteworthy that there are major differences in the required quality and quantity of hypoxia training for both military and civilian pilots.Keywords: cognitive response, aviation training, pilot, hypoxia, oxygen, loss of consciousness

    Much progress has been achieved over the past 20 years in remediating sites contaminated by heavy metal. However, very large contaminated areas have presented major problems to this day because of remediation costs. Phytoremediation is a new, emerging, sustainable technique of remediating areas with low heavy-metal contamination. One advantage of phytoremediation is the comparatively low cost of the process, which may make it usable also on large areas with low levels of contamination.

    Mixed germ cell tumors of the ovary have rarely been reported in veterinary species. A 3-year-old intact female Labrador Retriever dog was presented for lethargy, abdominal distention, and a midabdominal mass. An exploratory laparotomy revealed a large (23 cm in diameter) left ovarian tumor and multiple small (2-3 cm in diameter) pale tan masses on the peritoneum and abdominal surface of the diaphragm. Histological examination of the left ovary revealed a mixed germ cell tumor with a yolk sac component with rare Schiller-Duval bodies and a teratomatous component comprised primarily of neural differentiation. The abdominal metastases were solely comprised of the yolk sac component. The yolk sac component was diffusely immunopositive for cytokeratin with scattered cells reactive for α-fetoprotein and placental alkaline phosphatase. Within the teratomatous component, the neuropil was diffusely immunopositive for S100, neuron-specific enolase, and neurofilaments with a few glial fibrillary acidic protein immunopositive cells. Ovarian germ cell tumors may be pure and consist of only 1 germ cell element or may be mixed and include more than 1 germ cell element, such as teratoma and yolk sac tumor.

    Following the direct identification and measurements of Cosmic Ray Albedo Neutron Decay (CRAND) produced electrons near the inner edge of the inner belt by Colorado Student Space Weather Experiment (CSSWE)1, we extend the study by addressing more comprehensive questions: (1) what is the relative CRAND contribution to the inner belt compared with electrons injected from further out? (2) How does this relative contribution vary with geomagnetic activity and electron energy? (3) What is the solar cycle dependence of CRAND electrons? In order to answer the above questions, extended data of relativistic electrons in the inner belt are needed for a much longer time period and also finer energy resolution is required. Therefore, we will show results regarding the above questions based on data including other low Earth orbit measurements in addition to CSSWE, such as SAMPEX/PET, DEMETER/IDP, and PROBA-V/EPT.

  18. ... e no começo era a fome: três movimentos da dietética na criação do homem

    Henrique Figueiredo Carneiro

    Full Text Available Curiosamente, os mitos que conhecemos para dar conta da existencia humana tocam indiscutivelmente a presença da dietética, como condição inerente à hominização do vivente. Isso pode ser constatado nos mitos do Gênesis, de Theuth e do Pai da horda primitiva, mediante o texto "Totem e tabu". Essa constatação torna atual o aforismo de Schiller, ressaltando que a fome e o amor aparecem como a mola do universo. Essa questão, impõe, de princípio, uma reflexão sobre a importância do traço da dietética como uma marca na qual o homem constrói, mediante essa ação, um sentido à existência. Com isso, trabalhamos com a hipótese de que a dietética pos-sibilita uma referência epistêmica constante para o entendimento do lugar que o homem ocupa subjetivamente em determinada época; e, sobretudo, apresenta-se como uma linha de trabalho psicanalítico promissora, quando ratifica o sujeito como um produto da passagem realizada da natureza à cultura.

    Much progress has been achieved over the past 20 years in remediating sites contaminated by heavy metal. However, very large contaminated areas have presented major problems to this day because of remediation costs. Phytoremediation is a new, emerging, sustainable technique of remediating areas with low heavy-metal contamination. One advantage of phytoremediation is the comparatively low cost of the process, which may make it usable also on large areas with low levels of contamination. Besides extracting and immobilizing metals, respectively, phytoremediation among other things also contributes to improving soil quality in terms of physics, chemistry, and ecology. Consequently, phytoremediation offers a great potential for the future. Research into phytoremediation of an area contaminated by heavy metals and radionuclides is carried out on a site in a former uranium mining district in Eastern Thuringia jointly by the Friedrich Schiller University, Jena, and the Technical University of Dresden in a project funded by the German Federal Ministry for Education and Research.

    Described is an application in which an Artificial Neural Network (ANN) controls the positioning of a robot arm with five degrees of freedom by using visual feedback provided by two cameras. This application and the specific ANN model, local liner maps, are based on the work of Ritter, Martinetz, and Schulten. We extended their approach by generating a filtered, average positioning error from the continuous camera feedback and by coupling the learning rate to this error. When the network learns to position the arm, the positioning error decreases and so does the learning rate until the system stabilizes at a minimum error and learning rate. This abolishes the need for a predetermined cooling schedule. The automatic cooling procedure results in a closed loop control with no distinction between a learning phase and a production phase. If the positioning error suddenly starts to increase due to an internal failure such as a broken joint, or an environmental change such as a camera moving, the learning rate increases accordingly. Thus, learning is automatically activated and the network adapts to the new condition after which the error decreases again and learning is 'shut off'. The automatic cooling is therefore a prerequisite for the autonomy and the fault tolerance of the system.

The plant is used to treat prostate inflammation and urinary infection. The present work reports the first secondary metabolites isolated from P. pachycladus. Therefore, the isolated compound 4-hydroxy-3,5-dimethoxy benzaldehyde (syringaldehyde was evaluated as modulator of Staphylococcus aureus pump efflux-mediated antibiotic resistance. The isolation of compounds was performed using chromatographic techniques and the structural elucidation was carried out by spectroscopic methods. In order to evaluate syringaldehyde ability to modulate S. aureus antibiotic resistance, its minimum inhibitory concentrations (µg/ml was first determinate, then, the tested antibiotics minimum inhibitory concentrations were determined in the presence of the syringaldehyde in a sub-inhibitory concentration. The chromatographic procedures led to isolation of twelve compounds from P. pachycladus including fatty acids, steroids, chlorophyll derivatives, phenolics and a lignan. The syringaldehyde did not show any antibacterial activity at 256 µg/ml against S. aureus. On the other hand the compound was able to reduce the antibiotic concentration (tetracycline, norfloxacin, ethidium bromide required to inhibit the growth of drug-resistant bacteria, showing the ability of syringaldehyde of inhibiting the efflux pump on these bacteria.

    Priming is characterized by a sensitivity of reaction times to the sequence of stimuli in psychophysical experiments. The reduction of the reaction time observed in positive priming is well-known and experimentally understood (Scarborough et al., J. Exp. Psycholol: Hum. Percept. Perform., 3, pp. 1-17, 1977). Negative priming—the opposite effect—is experimentally less tangible (Fox, Psychonom. Bull. Rev., 2, pp. 145-173, 1995). The dependence on subtle parameter changes (such as response-stimulus interval) usually varies. The sensitivity of the negative priming effect bears great potential for applications in research in fields such as memory, selective attention, and ageing effects. We develop and analyse a computational realization, CISAM, of a recent psychological model for action decision making, the ISAM (Kabisch, PhD thesis, Friedrich-Schiller-Universitat, 2003), which is sensitive to priming conditions. With the dynamical systems approach of the CISAM, we show that a single adaptive threshold mechanism is sufficient to explain both positive and negative priming effects. This is achieved by comparing results obtained by the computational modelling with experimental data from our laboratory. The implementation provides a rich base from which testable predictions can be derived, e.g. with respect to hitherto untested stimulus combinations (e.g. single-object trials).

    The biomass productivity of microalgae cells mainly depends on the hydrodynamics of airlift bioreactor (ABR). Thus, the hydrodynamics of concentric tube ABR was initially studied using two-phase three-dimensional CFD simulations with the Eulerian-Lagrangian approach. The performance of ABR (17 L) was examined for different configurations of the draft tube using various drag models such as Grace, Ishii-Zuber, and Schiller-Naumann. The gas holdups in the riser and the downcomer were well predicted using E-L approach. This work was further extended to study the dispersion of microalgae cells in the ABR using three-phase CFD simulations. In this model (combined E-E and E-L), the solid phase (microalgae cells) was dispersed into the continuous liquid phase (water), while the gas phase (air bubbles) was modeled as a particle transport fluid. The effect of non-drag forces such as virtual mass and lift forces was also considered. Flow regimes were explained on the basis of the relative gas holdup distribution in the riser and the downcomer. The microalgae cells were found in suspension for the superficial gas velocities of 0.02-0.04 m s -1 experiencing an average shear of 23.52-44.56 s -1 which is far below the critical limit of cell damage.

A percepção estética está apoiada no imaginário ativamente trabalhado na psique dos alunos. A imaginação é a estratégia da arte autêntica em deixar o espectador ativo, mergulhado na participação ao criar vínculos corporais do sujeito com o outro, com o meio ambiente. A imagem criada não é cópia da imagem percebida. A atividade da imaginação com fim em si mesma tem como desafio a inércia da imaginação reprodutora.

    Full Text Available Scale has recently entered social anthropology as both a unit of analysis and a heuristic tool. This paper highlights the applicability to the anthropology of tourism of what has been identified as “projects of scale-making” by Tsing (2000 and respective “modes of incorporation” by Glick Schiller, Caglar and Guldbrandsen (2006. Because tourism is one of the central industries shaping present-day understandings of what is global and what is local, scale as a theoretical and methodological tool is ideally suited to study this field. Central concerns of anthropological research on tourism, such as the industry’s political economy, its influence on the perception of landscapes and culture as well as the problematic notion of authenticity, are reconsidered. We argue that central shortcomings of the globalisation debate, such as a teleologically-minded futurism, euphemistic notions of economic circulation and conflations of mundane and scientific debates, shape both the tourism industry and too many anthropological studies on tourism. In light of the contributions collected in this dossier this paper instead develops an analytical framework that highlights the hidden relations of production in tourism economies and the impacts of projects of scale-making on the construction of landscapes and culture.A escala foi recentemente incorporada na antropologia social como unidade de análise e ferramenta heurística.

    Our brain recordings reveal that large-scale sequential regularities defined across non-adjacent stimuli can be automatically represented in visual sensory memory. To show that, we adopted an auditory paradigm developed by Sussman, E., Ritter, W., and Vaughan, H. G. Jr. (1998). Predictability of stimulus deviance and the mismatch negativity. NeuroReport, 9, 4167-4170, Sussman, E., and Gumenyuk, V. (2005). Organization of sequential sounds in auditory memory. NeuroReport, 16, 1519-1523 to the visual domain by presenting task-irrelevant infrequent luminance-deviant stimuli (D, 20%) inserted among task-irrelevant frequent stimuli being of standard luminance (S, 80%) in randomized (randomized condition, SSSDSSSSSDSSSSD...) and fixed manners (fixed condition, SSSSDSSSSDSSSSD...). Comparing the visual mismatch negativity (visual MMN), an event-related brain potential (ERP) index of memory-mismatch processes in human visual sensory system, revealed that visual MMN elicited by deviant stimuli was reduced in the fixed compared to the randomized condition. Thus, the large-scale sequential regularity being present in the fixed condition (SSSSD) must have been represented in visual sensory memory. Interestingly, this effect did not occur in conditions with stimulus-onset asynchronies (SOAs) of 480 and 800 ms but was confined to the 160-ms SOA condition supporting the hypothesis that large-scale regularity extraction was based on perceptual grouping of the five successive stimuli defining the regularity. 2010 Elsevier B.V.

    We present the results of a time series analysis of 130 échelle spectra of ε Ori (B0 Ia), acquired over seven observing seasons between 1998 and 2006 at Ritter Observatory. The equivalent widths of Hα (net) and He I λ5876 were measured and radial velocities were obtained from the central absorption of He I λ5876. Temporal variance spectra (TVS) revealed significant wind variability in both Hα and He I λ5876. The He I TVS have a double-peaked profile consistent with radial velocity oscillations. A periodicity search was carried out on the equivalent width and radial velocity data, as well as on wavelength-binned spectra. This analysis has revealed several periods in the variability with timescales of two to seven days. Many of these periods exhibit sinusoidal modulation in the associated phase diagrams. Several of these periods were present in both Hα and He I, indicating a possible connection between the wind and the photosphere. Due to the harmonic nature of these periods, stellar pulsations may be the origin of some of the observed variability. Periods on the order of the rotational period were also detected in the He I line in the 1998-1999 season and in both lines during the 2004-2005 season. These periods may indicate rotational modulation due to structure in the wind.

    A time-series analysis of spectroscopic and photometric observables of the A0 Ia supergiant HR 1040 has been performed, including equivalent widths, radial velocities, and Strömgren photometric indices. The data, obtained from 1993 through 2007, include 152 spectroscopic observations from the Ritter Observatory 1 m telescope and 269 Strömgren photometric observations from the Four College Automated Photoelectric Telescope. Typical of late B- and early A-type supergiants, HR 1040 has a highly variable Hα profile. The star was found to have an intermittent active phase marked by correlation between the Hα absorption equivalent width and blue-edge radial velocity and by photospheric connections observed in correlations to equivalent width, second moment and radial velocity in Si ii λλ6347, 6371. High-velocity absorption (HVA) events were observed only during this active phase. HVA events in the wind were preceded by photospheric activity, including Si ii radial velocity oscillations 19–42 days prior to onset of an HVA event and correlated increases in Si ii W λ and second moment from 13 to 23 days before the start of the HVA event. While increases in various line equivalent widths in the wind prior to HVA events have been reported in the past in other stars, our finding of precursors in enhanced radial velocity variations in the wind and at the photosphere is a new result

  2. QUIPS: Time-dependent properties of quasi-invariant self-gravitating polytropes

    Quasi-invariance, a method based on group tranformations, is used to obtain time-dependent solutions for the expansion and/or contraction of a self-gravitating sphere of perfect gas with polytopic index n. Quasi-invariance transforms the equations of hydrodynamics into ''dual equations'' exhibiting extra terms such as a friction, a mass source or sink term, and a centripetal/centrifugal force. The search for stationary solutions in this ''dual space'' leads to a new class of time-dependent solutions, the QUIP (for Quasi-invariant polytrope), which generalizes Emden's static model and introduces a characteristic frequency a related to Jean's frequency. The second order differential equation describing the solution is integrated numerically. A critical point is seen always to exist for nnot =3. Solutions corresponding in the ''dual space'' to a time-dependent generalization of Eddington's standard model (n = 3) are discussed. These solutions conserve both the total mass and the energy. A transition between closed and open structures is seen to take place at a particular frequency a/sub c/. For n = 3, no critical point arises in the ''dual space'' due to the self-similar motion of the fluid. A new time-dependent mass-radius relation and a generalized Betti-Ritter relation are obtained. Conclusions about the existence of a minimum Q-factor are presented

    Oswald Schwarz, a urologist from Vienna, was a scholar of Anton Ritter von Frisch and Hans Rubritius. As a physician during World War I, he was confronted with numerous bullet wounds to the spinal cord. In 1919, he completed his professorial thesis"Bladder dysfunction as a result of bullet wounds to the spinal cord". Oswald Schwarz was known as a committed surgeon. As an urologist he also treated patients with sexual dysfunction. Besides his practical and scientific urology-related work, he was also interested in psychology and philosophy. He held lectures on both subjects earning himself the nickname, the Urosoph. In the 1920s, Oswald Schwarz belonged to the inner circle of Alfred Adler, the founder of Individual Psychology, and was editor of the first psychosomatic textbook published in German, "Psychological origin and psychotherapy of physical symptoms" (1925). In addition, Schwarz wrote numerous articles and several books on sexual medicine. He also made many valuable contributions to the development of medical anthropology. Altogether, his work includes over 130 publications. Faced with the rise of fascism and National Socialism in Europe, Oswald Schwarz, who was of Jewish origin, emigrated to England in 1934. There he died in 1949. Unfortunately his scientific work has largely been forgotten. The aim of the following article is to remind us of his important contributions to the field.

    Full Text Available Aleksandar R Zivkovic, Jochen Bender, Thorsten Brenner, Stefan Hofer,* Karsten Schmidt* Department of Anesthesiology, Heidelberg University Hospital, Heidelberg, Germany *These authors contributed equally to this work Purpose: Early diagnosis of systemic inflammatory response syndrome is fundamentally important for an effective and a goal-directed therapy. Various inflammation biomarkers have been used in clinical and experimental practice. However, a definitive diagnostic tool for an early detection of systemic inflammation remains to be identified. Acetylcholine (Ach has been shown to play an important role in the inflammatory response. Serum cholinesterase (butyrylcholinesterase [BChE] is the major Ach hydrolyzing enzyme in blood. The role of this enzyme during inflammation has not yet been fully understood. This study tests whether a reduction in the BChE activity could indicate the onset of the systemic inflammatory response upon traumatic injury. Patients and methods: This observational study measured BChE activity in patients with traumatic injury admitted to the emergency room by using point-of-care-test system (POCT. In addition, the levels of routine inflammation biomarkers during the initial treatment period were measured. Injury Severity Score was used to assess the trauma severity. Results: Altered BChE activity was correlated with trauma severity, resulting in systemic inflammation. Reduction in the BChE activity was detected significantly earlier compared to those of routinely measured inflammatory biomarkers. Conclusion: This study suggests that the BChE activity reduction might serve as an early indicator of acute systemic inflammation. Furthermore, BChE activity, measured using a POCT system, might play an important role in the early diagnosis of the trauma-induced systemic inflammation.

    Modeling of the global distribution of atmospheric ethane sources and sinks by using the 13C isotopic composition requires accurate knowledge of the carbon kinetic isotope effect (KIE) of its atmospheric removal reactions. The quantum mechanical prediction implies the necessity to elucidate the temperature dependence of KIE within atmospherically relevant temperature range by experiment. In this study, the KIE and its temperature dependence for ethane oxidation by OH radicals was investigated at ambient pressure in a temperature range of 243 K to 303 K. The chemical reactions were carried out in a 15 L PFE reaction chamber, suspended in a thermally controlled oven. The isotope ratios of the gas phase components during the course of the reactions were measured by Thermal Desorption -- Gas Chromatography -- Isotope Ratio Mass Spectrometry (TD-GC-IRMS). For each temperature, the KIE was derived from the temporal evolution of the concentration and stable carbon isotope ratio (δ13C) of ethane using a method adapted from the relative reaction rate concept. The room temperature KIE of the ethane reaction with OH radicals was found to be 6.85 ± 0.32 ‰. This value is in agreement with the previously reported value of 8.57 ± 1.95 ‰ [Anderson et al. 2004] but has a substantially lower uncertainty. The experimental results will be discussed with the KIE temperature dependence predicted by quantum mechanical calculations. Reference: Rebecca S. Anderson, Lin Huang, Richard Iannone, Alexandra E.

    Full Text Available  Criar significa destruir também. A genialidade cobra um preço alto: a angústia, a vida dilacerada. A chama que ilumina mais, dura menos. Amy Winehouse não foi a primeira e provavelmente não será a última artista genial a entrar em um processo autodestrutivo. Um processo de total perda de esperança resultando na busca deliberada pela morte. No Romantismo Alemão vários escritores e filósofos falaram sobre o peso da genialidade. Schelling coloca que o gênio é capaz da mesma intuição criadora do Espírito Absoluto. Schopenhauer nos fala da dor de ser gênio. Nietzsche, como Schiller, defende a genialidade artística como o único objetivo digno da vida humana. A vida é arte e cabe a nós desenvolvermos essa arte. Os poetas malditos, as estrelas do rock e do jazz celebraram esta festa, a vida, mesmo que, ao final, não haja mais vida alguma. Diante de um fenômeno midiático como Amy Winehouse, como podemos compreender toda essa reflexão filosófica sobre arte, vida, genialidade e morte?  Palvras-chave: Filosofia. Amy Winehouse. Genialidade. Romantismo Alemão.

    Full Text Available In 1786 in Rome, Johann Wolfgang Goethe wrote about him: “He is my younger brother; we art cut from the same mould. However, fate was against him, whereas I was fortune’s favourite.” He meant Karl Phillip Moritz (1756-1793, a German writer and art critic, Greek mythology historian, precursor of modern psychology and the author of psychological novel. If we assume that Goethe’s comments concern Moritz’s material and social status only, we would have to admit that Goethe was right. However, if we apply these judgments to the quality of his (Moritz’s works, we would be inclined to saying that in this case the great Goethe was wrong. In his aesthetic, Moritz is far more interesting and progressive than his “elder brother”; in his literary criticism – more consistent than Schiller, and in perceiving society and politics – more radical than Kant. This article is mainly on key concept regarding Moritz’s aesthetic works: the concept of beauty and its functionalism. Definition of “the work of art” as a closed, specified unity enables Moritz to get out of the frame of aesthetics itself and to enter the sphere of politics. Moritz liberates man from the restraints of utility and treats him as a noble individual who possesses the artistic value in himself.

Patients and methods: Examination time was measured in 100 patients scanned with conventional protocol (Group A: arms positioned alongside the body for head and neck imaging and over the head for trunk imaging and 100 patients scanned with optimized protocol (Group B: arms flexed on a chest pillow without repositioning. Additionally, influence of two different scanning protocols on image quality in the most relevant body regions was assessed by two blinded readers. Results: Total wbCT duration was about 35% or 3:46 min shorter in B than in A. Artifacts in aorta (27 vs 6%, liver (40 vs 8% and spleen (27 vs 5% occurred significantly more often in B than in A. No incident of non-diagnostic image quality was reported, and no significant differences for lungs and spine were found.

We herein describe the case of a 69-year-old male patient reporting uncontrolled movements of the right arm due to a muscle weakness, slurred speech, and paresthesia in the oral region some seconds after he had blown his nose. These neurological symptoms had improved dramatically within a few minutes and were completely regressive at admission to our hospital about two hours later. On transesophageal echocardiography (TEE a huge ASA associated with PFO was detected. Diagnosis of the large-sized ASA was also confirmed by cardiac magnetic resonance imaging. Due to the early complete recovery from his neurological symptoms, the patient was diagnosed with a transient ischemic attack (TIA. After nine days he was discharged in a good clinical condition under the treatment with oral anticoagulation. It is concluded that in cryptogenic or unexplained stroke or TIA TEE should always be performed to rule out ASA and PFO as potential sources for paradoxical embolism in those inconclusive clinical situations.

    The late-type Be star β CMi is remarkably stable compared to other Be stars that have been studied. This has led to a realistic model of the outflowing Be disk by Klement et al. These results showed that the disk is likely truncated at a finite radius from the star, which Klement et al. suggest is evidence for an unseen binary companion in orbit. Here we report on an analysis of the Ritter Observatory spectroscopic archive of β CMi to search for evidence of the elusive companion. We detect periodic Doppler shifts in the wings of the H α line with a period of 170 days and an amplitude of 2.25 km s{sup −1}, consistent with a low-mass binary companion ( M ≈ 0.42 M {sub ⊙}). We then compared small changes in the violet-to-red peak height changes ( V / R ) with the orbital motion. We find weak evidence that it does follow the orbital motion, as suggested by recent Be binary models by Panoglou et al. Our results, which are similar to those for several other Be stars, suggest that β CMi may be a product of binary evolution where Roche lobe overflow has spun up the current Be star, likely leaving a hot subdwarf or white dwarf in orbit around the star. Unfortunately, no direct sign of this companion star is found in the very limited archive of International Ultraviolet Explorer spectra.

  15. STUDYING DEFORMATIONS OF AN FLAT TRUSS STRUCTURE STATICALLY INDETERMINATED EXTERNALLY

    Full Text Available A flat statically determinate parallel-chord truss structure has a cross-shaped grid and rests upon two rigid pin-bearing supports. Loads in bars are determined in a symbol form using the method of joint isolation by the computer mathematics Maple system. The peculiarity of the considered truss structure is its external static indeterminacy. In fact, all efforts and reactions of supports can be determined from the equilibrium conditions. But the inconvenience is necessary to consider the equilibrium of all the nodes of the truss. The Ritter cross-section method is not applicable to this truss structure. The sections that cut the truss into two parts and pass through the three rods, here exist only for several rods of the extreme panels. The purpose of this paper is to calculate a truss structure with a different number of panels in analytical and numerical form. Finite element calculation method with the use of software LISA 8.0 is applied. It’s noted that a truss structure is kinetically changeable when the number of spans is odd. The corresponding plan of probable velocities is given. In order to receive analytic dependence of deflection on the span number, the induction method and Maxwell-Moor formula has been applied. The operators of the compilation and solution of recurrence equations are involved in determining the general terms of the coefficient sequences. The formulas for calculation of loads in the most compressed bars of a truss structure were received.

P. pachycladus showed the greatest use value, versatility and number of plant parts used. The survey showed that the Cactaceae is extremely important for several uses and categories attributed to different species. Apart from contributing to the ethnobotanical knowledge of the Cactaceae, another important focus of this study was to reinforce the necessity for further studies that record the traditional knowledge about this plant family, which has been lost in younger generations.

    Full Text Available Article in Spanish, Abstracts in English and German.The article “Humboldization of the Western world? The importance of the travel of Humboldt for Europa and for Latin America”, treats the empirical Prussian Scientist as a globalist (Universalgelehrten, in accordance to the conceptualization made by Ottmar Ette. Humboldt was one, if not the most important founder of Western moderne. As opposed to the well-known founders of the moderne (Descartes, Kant, Buffon, Schiller, Hegel, Marx ... etc., Alexander von Humboldt was an empirical and a global thinker. He did this in transcultural manners, sometimes already in intercultural manners. But most of times, his point of view is based in the European tradition of roman-classicist and aesthetic thinking. The article tries to demonstrate three types of knowledge in Humboldt and also, that the humboldtian universalism has important intercultural bases in the comunication with American scientists and in the American empiricism (“local knowledge”. One importance of such a conceptualization of Humboldt is shown – in negation – in the actual debates over diaspora and race in the Atlantic world (“Black Atlantic”. Humboldt knowledge of American slaveries and his absolute condemnation of slavery in his “Island of Cuba” is not present in these debates. In the second part the article demonstrates possibles manners of reading the diaries of Humboldt, by constructing “essais imaginaires” about colonialism, slavery, Peru, the Pacific ocean etc.

    The Abbe School of Photonics (ASP) provides and coordinates the optics and photonics education of graduate and doctoral students at the Friedrich Schiller University in Jena, Germany. The internationalized Master's degree program is the key activity in training students in the optical sciences. The program is designed to provide them with the skills necessary to fill challenging positions in industry and academia. Here, an essential factor is ASP's close collaboration with more than 20 German photonics companies. To sustain these partners' future economic development, the availability of highly qualified employees is constantly required. Accordingly, these industrial partners, the European Union, the local state and the federal German government are strongly involved in the sustainable development of ASP's curriculum by both conceptual and financial engagements. The main goal is to promote the students' academic careers and job experience in the photonics industry as well as in academia. To open up the program to students from all over the world, all ASP lectures and courses are taught in English. Since 2009, more than 250 graduate students from more than 40 different countries have been enrolled at the School. Almost 90% of them of non-German nationality, fulfilling the essential ASP philosophy to locally establish an international education program. ASP's qualification strategy is fully research-oriented and based on the principles of academic freedom, competitive research conditions and internationalization at all levels. The education program is complemented by a structured doctoral student support and a prestigious guest professorship program.

    Broad criteria for abnormal electrocardiogram (ECG) findings, requiring additional testing, have been recommended for preparticipation exams (PPE) of athletes. As these criteria have not considered the sport in which athletes participate, we examined the effect of sports on the computerized ECG measurements obtained in college athletes. During the Stanford 2007 PPE, computerized 12-lead ECGs (Schiller AG) were obtained in 641 athletes (350 male/291 female, age 19.5 ± 2 years). Athletes were engaged in 22 different sports and were grouped into 16 categories: baseball/softball, basketball, crew, crosscountry, fencing, field events, football linemen, football other positions, golf, gymnastics, racquet sports, sailing, track/field, volleyball, water sports, and wrestling. The analysis focused on ECG leads V2, aVF and V5 which provide a three-dimensional representation of the heart's electrical activity. As marked ECG differences exist between males and females, the data are presented by gender. In males, ANOVA analysis yielded significant ECG differences between sports for heart rate, QRS duration, QTc, J-amplitude in V2 and V5, spatial vector length (SVL) of the P wave, SVL R wave, and SVL T wave, and RS(sum) (p sports were found for heart rate, QRS duration, QRS axis and SVL T wave (p sports, and these differences were more apparent in males than females. Therefore, sport-specific ECG criteria for abnormal ECG findings should be developed to obtain a more useful approach to ECG screening in athletes.

    Full Text Available At present, despite the availability of modern effective oral hygiene means and prevention of dental diseases, which reduced their intensity, disease prevalence remains high. One method of dental caries preventing in children aged 6-7 years is a fissure sealing of molars, the most vulnerable areas of the newly erupted teeth, having a number of problems associated with a complex fissures relief. The purpose of this study was to investigate the prevalence and intensity of dental diseases and their development trends, as well as indicators of electrometric fissures of teeth in children aged 6-7 years of Simferopol. 87 children aged 6-7 years (first classes schools in Simferopol were examined. In this case, assessed the state of hard dental tissues (CFt, CFf, CFDt, CFDf, cavities, fillings, chalk spots, depigmentation, complications in the structure of lesions, the state of periodontal tissue (PMA%, bleeding, Schiller-Pisarev test, CPITN and oral hygiene (Silness-Loe, Stallard were examined. For diagnosing electrometry of hard tissues of dental fissures DentEst apparatus was used. Studies of major dental diseases and electrometric indicators of hard tissues of molars fissures in children under study testifies to a high caries incidence in temporary and permanent teeth and a tendency to increase of caries prevalence of permanent occlusion in these children, poor oral hygiene and the need to develop and implement treatment and preventive measures that not allow the development of caries process in the teeth of permanent occlusion.

  1. 'Man muss die Dinge sich vor Augen halten ...': Goethe’s and Adorno’s aesthetic programmes as a critique of Modernity

    2011-07-01

    Full Text Available Early on in his acquaintance with Goethe, Schiller criticised Goethe‟s „philosophy‟ as too subjective: „It takes too much from the world of [the] senses, whereas I take from the soul.‟ Today, subjectivity is the opposite to the „objective‟ world experienced via the senses – a view that can be traced back to the early Scotist thinking on subjective versus objective truth. In the first part of this article, close textual analysis of Goethe‟s Farbenlehre („On the theory of colour‟ and Wahlverwandtschaften („Elective affinities‟, demonstrates how Goethe aligns the cognition of truth with a subjective function of participatory observation; which he sees as truly empirical. These texts from very different genres execute the same aesthetic programme, in which the narrator withdraws to invite the reader to see for him-/ herself. In the second part, Goethe‟s concept of participatory truth-finding is compared to Adorno‟s aesthetic theory – Adorno claims that only the non-identical appears momentarily in artwork. The comparison between Goethe‟s „Aperçu‟ and Adorno‟ s „Apparition‟, Goethe‟s „zarte Empirie‟ and Adorno‟s incommensurable insight of art, supports the argument that Adorno‟s dilemma in grappling with the absolute can be overcome by using Goethe‟s relativising stance. This approach interprets knowledge as a set of cultural-historical concepts, emphasising the pivotal position and relevance of literary studies.

  2. Visual search among items of different salience: removal of visual attention mimics a lesion in extrastriate area V4.

    1994-02-01

    In more than one respect, visual search for the most salient or the least salient item in a display are different kinds of visual tasks. The present work investigated whether this difference is primarily one of perceptual difficulty, or whether it is more fundamental and relates to visual attention. Display items of different salience were produced by varying either size, contrast, color saturation, or pattern. Perceptual masking was employed and, on average, mask onset was delayed longer in search for the least salient item than in search for the most salient item. As a result, the two types of visual search presented comparable perceptual difficulty, as judged by psychophysical measures of performance, effective stimulus contrast, and stability of decision criterion. To investigate the role of attention in the two types of search, observers attempted to carry out a letter discrimination and a search task concurrently. To discriminate the letters, observers had to direct visual attention at the center of the display and, thus, leave unattended the periphery, which contained target and distractors of the search task. In this situation, visual search for the least salient item was severely impaired while visual search for the most salient item was only moderately affected, demonstrating a fundamental difference with respect to visual attention. A qualitatively identical pattern of results was encountered by Schiller and Lee (1991), who used similar visual search tasks to assess the effect of a lesion in extrastriate area V4 of the macaque.

    , immunohistochemistry, cytogenetics, molecular pathology) gain place, the increasing tendency to select investigators, including basic scientists, as teaching department chairs and the financial constraints requiring increasing use of nonphysician workers all speak to the relegation of the Otani-Kaneko era to history. Is this a loss to Pathology? It is certainly a style of practice that has been lost. However, there is no reason to bemoan the state of Pathology in the beginning years of the 21st century. Pathology practice is outstanding at many medical centers throughout the world, including at Mount Sinai under the very able and creative leadership of Alan Schiller, who has presided over great enhancements of the department in both anatomic and clinical pathology, including significant advances in the study of diseases by molecular methods. Surgical Pathology at Mount Sinai has been led by James Strauchen, a renowned hematopathologist recruited by Schiller's predecessor, Jerome Kleinerman, and is currently directed by Ira Bleiweiss, a student of Kaneko. Other techniques and technologies have, to a degree, compensated for some of the changes since the Otani-Kaneko years and it is almost certain that advances in molecular pathology will allow for increasing sophistication in establishing diagnoses, and likely even grading and staging, probably even on blood, rather than tissue, samples. The science of Pathology will advance, as the art declines. Those who learned at Mount Sinai during the Otani-Kaneko years will, however, very likely tell you that they were privileged to have learned Pathology there and, especially, to have learned a distinct philosophy of Pathology under the guidance of caring, thoughtful, and especially gifted pathologists.

    Metamorphosed Mesozoic volcanic rocks from the E-central Sierra Nevada range in composition from basalt to rhyolite and have ages, based on whole rock Rb-Sr and U-Pb zircon dating, of about 237- 224, 185, 163, 134, and 100Ma. The major plutons of the batholith in this area are of Triassic (215-200Ma) and Cretaceous (94-80Ma) ages. Initial 87Sr/86Sr values for the metamorphosed volcanic rocks of the area are in the range from 0.7042 to 0.7058 and are generally different from the values for the surrounding batholithic rocks (0.7056-0.7066). A circular, zoned granitic pluton, with an outcrop area of 2.5km2, similar in appearance to a ring dike complex, was apparently a conduit for some or possibly all of the middle-Cretaceous metamorphosed volcanic rocks exposed about 5km to the S in the western part of the Ritter Range. Samples from the metamorphosed volcanic rocks and the pluton yield a Rb/Sr whole rock isochron age of 99.9+ or -2.2Ma with an intitial 87Sr/86Sr of 0.7048+ or -0.00001. Major element variation diagrams of the pluton and volcanic rocks define coincident compositional trends. The ages of volcanic events relative to the ages of the major intrusive epochs and the major element and isotopic compositions of the volcanic rocks relative to the major plutons indicate that the volcanic rocks are not simply or directly related to the major plutons in the Sierra Nevada. -from Authors

    Full Text Available In this work, the development of solar theory is followed from the concept that the Sun was an ethereal nuclear body with a partially condensed photosphere to the creation of a fully gaseous object. An overview will be presented of the liquid Sun. A powerful lineage has brought us the gaseous Sun and two of its main authors were the direct sci- entific descendants of Gustav Robert Kirchhoff: Franz Arthur Friedrich Schuster and Arthur Stanley Eddington. It will be discovered that the seminal ideas of Father Secchi and Herv ́ e Faye were not abandoned by astronomy until the beginning of 20th century. The central role of carbon in early solar physics will also be highlighted by revisit- ing George Johnstone Stoney. The evolution of the gaseous models will be outlined, along with the contributions of Johann Karl Friedrich Z ̈ ollner, James Clerk Maxwell, Jonathan Homer Lane, August Ritter, William Thomson, William Huggins, William Edward Wilson, George Francis FitzGerald, Jacob Robert Emden, Frank Washington Very, Karl Schwarzschild, and Edward Arthur Milne. Finally, with the aid of Edward Arthur Milne, the work of James Hopwood Jeans, the last modern advocate of a liquid Sun, will be rediscovered. Jeans was a staunch advocate of the condensed phase, but deprived of a proper building block, he would eventually abandon his non-gaseous stars. For his part, Subrahmanyan Chandrasekhar would spend nine years of his life studying homogeneous liquid masses. These were precisely the kind of objects which Jeans had considered for his liquid stars.

  6. Poetry, Nature and Science: Romantic Nature Philosophy in the Works of Novalis and E. T. a. Hoffmann

    Science.gov (United States)

    Weisend, Ausma Skerbele

    The nature philosophy of the early Romantic period in Germany attempted to find a synthesis of science and philosophy in a new philosophy of nature. This philosophy was first formulated by F. W. J. Schelling and influenced by the galvanic experiments of J. W. Ritter. Novalis is a unique figure in romanticism since he combines scientific expertise with philosophical insight and poetic imagination. In Lehrlinge zu Sais he explores the significance of nature's language and presents different relationships between man and nature. Novalis thinks that a synthesis of all divergent elements in nature and society is necessary to transform the world. In Klingsohrs Marchen this transformation is accomplished by poetic activation of the physical sciences and by the power of love. After 1800 the romantic movement becomes interested in the problems of subconscious and abnormal psychological states, which are seen as contacts with a more spiritual level of existence. These ideas, expressed in a popular form by G. H. Schubert, provide a rich source of materials for E. T. A. Hoffmann, who elevates the realms of poetry and music in his fairy tales, but sees only negative qualities in science. Hoffmann's protagonists find that love, music, and poetry are the greatest forces in life. The figure of the scientist becomes an evil magician with no regard for human values. The romantic movement failed to unite the values of humanities with the insights of physical sciences. The problem of autonomy isolates both modern science and modern literature from the ethical values of society.

    Understanding human behavior under the effects of sleep deprivation allows for the mitigation of risk due to reduced performance. To further this goal, this study investigated the effects of short-term sleep deprivation using a tilt-based control device and examined whether existing user models accurately predict targeting performance. A task in which the user tilts a surface to roll a ball into a target was developed to examine motor performance. A model was built to predict human performance for this task under various levels of sleep deprivation. Every 2 h, 10 subjects completed the task until they reached 24 h of wakefulness. Performance measurements of this task, which were based on Fitts' law, included movement time, task throughput, and time intercept. The model predicted significant performance decrements over the 24-h period with an increase in movement time (R2 = 0.61), a decrease in throughput (R2 = 0.57), and an increase in time intercept (R2 = 0.60). However, it was found that in experimental trials there was no significant change in movement time (R2 = 0.11), throughput (R2 = 0.15), or time intercept (R2 = 0.27). The results found were unexpected as performance decrement is frequently reported during sleep deprivation. These findings suggest a reexamination of the initial thought of sleep loss leading to a decrement in all aspects of performance.Bolkovsky JB, Ritter FE, Chon KH, Qin M.

    When a memory is recalled, it may again exist in a labile state and stored information becomes amenable to change, a psychobiological process known as reconsolidation. Exposure therapy for anxiety disorders involves accessing a fear memory and modifying it with less fearful information. A preclinical study reported that providing a reminder of a fear memory 10 min prior to extinction training in humans decreased fear up to 1 year later (Schiller et al., 2010). For this pilot clinical study, we used virtual reality exposure therapy (VRE) for fear of flying (FoF) to determine if using a cue to reactivate the memory of the feared stimulus 10 min prior to exposure sessions leads to fewer anxiety-related behaviors and a more durable response compared to a neutral cue. FoF participants (N = 89) received four sessions of anxiety management training followed by four sessions of VRE. Participants were randomly assigned to receive an FoF cue (reactivation group) or a neutral cue (control group) prior to the VRE sessions. Heart rate (HR) and skin conductance levels (SCLs) were collected during posttreatment and 3-month follow-up assessments as objective markers of fear responding. Treatment was effective and all clinical measures improved equally between groups at posttreatment with maintained gains through follow-ups. Significant differences were identified with regard to HR and SCL indices. These results suggest that memory reactivation prior to exposure therapy did not have an impact on clinical measures but may enhance the effect of exposure therapy at the physiological level. © 2017 Wiley Periodicals, Inc.

    Magdalena Śniedziewska

    2010-01-01

    Full Text Available The present article analyses the rough drafts of Zbigniew Herbert’s essay on Hendrik Avercamp — the seventeenth century Dutch landscape painter who specialized in winter landscapes and scenes with numerous tiny figures. The author attempts to reconstruct the compositional idea for the essay and establishes facts concerning the research work done by Herbert concerning the life and work of Avercamp, confronts the findings with the present state of research and considers the issue of the biographical dimension of the painter’s artistic output as one of the keys to solving the interpretative problems of his paintings and the artistic tradition that had influenced the shaping of the Avercamp idiom of paintings. Avercamp’s works are juxtaposed in the article with the landscapes painted by Pieter Bruegel the Elder to show the difference between the visions of the world represented by the two painters. Bruegel, in Herbert’s opinion, is bitter in his reflection on the subject of transiency of human existence. Avercamp, conversely, tends to have a cheerful outlook on life, the world and his compatriots. Avercamp’s paintings allow us to get to know winter customs of the Dutch, their winter outdoor games participated by all — hence a thesis posed by the poet underlying the democratic character of skating rinks. In doing so, Herbert proposes to scrutinize carefully Avercamp’s artistic output within the context of, defined after Schiller, the notion of naivety, understood as “the virtue of accepting reality with humility” adopted from the old masters.

    This study analyses three decades of the peculiar bloom-formation history of the potentially toxic invasive planktonic dinoflagellates Prorocentrum minimum (Pavillard) Schiller in the SW Baltic Sea. We tested a research hypothesis that the unexpectedly long delay (nearly two decades) in population development of P. minimum prior to its first bloom was caused by competition with one or several closely related native dinoflagellate species due to ecological niche partitioning which hampered the spread and bloom-forming potential of the invader. We applied the ecological niche concept to a large, long-term phytoplankton database and analysed the invasion history and population dynamics of P. minimum in the SW Baltic Sea coastal waters using the data on phytoplankton composition, abundance and biomass. The ecological niche dimensions of P. minimum and its congener P. balticum were identified as the optimum environmental conditions for the species during the bloom events based on water temperature, salinity, pH, concentration of nutrients (PO 4 3- ; total phosphorus, TP; total nitrogen, TN; SiO 4 4- ), TN/TP-ratio and habitat type. The data on spatial distribution and ecological niche dimensions of P. minimum have contributed to the development of the "protistan species maximum concept". High microplankton diversity at critical salinities in the Baltic Sea may be considered as a possible reason for the significant niche overlap and strong competitive interactions among congeners leading to prolonged delay in population growth of P. minimum preceding its first bloom in the highly variable brackishwater environment.

    Full Text Available Introduction: There are different proofs about association of autonomic nervous system dysfunction, especially nonlinear parameters, with higher mortality after myocardial infarction. Objective The objective of the study was to determine predictive value of Poincare plot as nonlinear parameter and other significant standard risk predictors: ejection fraction of the left ventricle, late potentials, ventricular arrhythmias, and QT interval. Method The study included 1081 patients with mean follow up of 28 months (ranging fom 0-80 months. End-point of the study was cardiovascular mortality. The following diagnostic methods were used during the second week: ECG with commercial software Schiller AT-10: short time spectral analysis of RR variability with analysis of Poincare plot as nonlinear parameter and late potentials; 24-hour ambulatory ECG monitoring: QT interval, RR interval, QT/RR slope, ventricular arrhythmias (Lown >II; echocardiography examinations: systolic disorder (defined as EF<40 %. Results There were 103 (9.52% cardiovascular deaths during the follow-up. In univariate analysis, the following parameters were significantly correlated with mortality: mean RR interval < 800 ms, QT and RR interval space relationship as mean RR interval < 800 ms and QT interval > 350 ms, positive late potentials, systolic dysfunction, Poincare plot as a point, ventricular arrhythmias (Lown > II. In multivariate analysis, the significant risk predictors were: Poincare plot as a point and mean RR interval lower than 800 ms. Conclusion Mean RR interval lower than 800 ms and nonlinear and space presentation of RR interval as a point Poincare plot were multivariate risk predictors.

    Secoisolariciresionol diglucoside (SDG) is a plant lignan isolated from flaxseed and is phytoestrogen. SDG is a potent and long-acting hypotensive agent. Plant phytoestrogens have inhibitory effects on angiotensin-converting enzyme (ACE). The hypotensive effects of SDG, a phytoestrogen, may be mediated through inhibition of ACE. The objective of this study was to investigate if SDG-induced hypotension is mediated through inhibition of ACE. The Sprague Dawley male rats were anesthetized and trachea was cannulated. The right jugular vein was cannulated to administer the drug and the carotid artery was cannulated to record arterial pressures using PIOEZ-1 miniature model transducer (Becton, Dickinson and Company, Franklin Lakes, NJ) and Beckman dynograph (Beckman Instruments, Inc., Schiller Park, IL). The effects of angiotensin I (0.2 µg/kg, intravenously [IV]) in the absence and presence of SDG (10 mg/kg, IV), and SDG alone on systolic, diastolic, and mean arterial pressures were measured before and after 15, 30, and 60 minutes of drug administration. SDG decreased the systolic, diastolic, and mean arterial pressure by 37, 47, and 43%, respectively, at 15 minutes and 18.8, 21.2, and 20.3%, respectively, at 60 minutes. Angiotensin I increased the arterial pressure. SDG decreased angiotensin I-induced rise in the systolic, diastolic, and mean arterial pressures by 60, 58, and 51%, respectively, at 15 minutes and 48, 46, and 30%, respectively, at 60 minutes. The data suggest that SDG reduced the angiotensin I-induced rise in the arterial pressures and hence SDG is a potent ACE inhibitor.

  15. Medium rare or well done - how would you like your snail? Influence of cooking practices on the isotopic composition of land snails' shells

    Since the seminal work of Goodfriend (1992, EPSL 11), several studies confirmed a relation between the isotopic composition (δ18O, δ13C) of land snail shell carbonate, and environmental parameters like precipitation amount, moisture source, temperature and vegetation. This relation, however, is not straightforward and, importantly, site dependent. The choice of sampling strategy (discrete or bulk sampling), cleaning procedure, and/or pre-depositional history further complicate the shell analysis. The advantage of using snail shells as environmental archive lies in their limited mobility, and thus an intrinsic aptitude of recording local and site-specific conditions. However, snail shells found at archaeological sites, even if of local origin, often represent a dietary component and boiling/roasting could potentially alter the isotopic signature of aragonite material. While thermal processing affects the clumped isotope composition of carbonates, its influence on traditional isotopes is still debated (Ritter et al. 2017, Sedimentology; Müller et al. 2017, Scientific Reports). Consequently, a proper sampling strategy is of great importance and should be chosen according to scientific question. Horizontal high-resolution shell sampling (drill holes along growth axis, across growth lines) provides insights into the amplitude of seasonal variability, while vertical high-resolution sampling (multiple drill holes along the same growth line) produces reproducible results. We took advantage of this reproducibility and, on a yet unprecedented scale, experimentally and sequentially tested the influence of boiling on the δ18O and δ13C signature of shells of modern Helix pomatia. Our results challenge recent reports on alteration due to boiling (Müller et al., 2017, Scientific Reports) and support uncompromised application of snail shells from archeological sites for paleoenvironmental reconstructions.

    The structures of health systems impact on patient outcomes. We present and analyse the first detailed mapping of who funds alcohol and other drug (AOD) treatment and the channels and intermediaries through which funding flows from the funding sources to treatment providers. The study involved a literature review of AOD treatment financing and existing diagrammatic representations of the structure of the Australian health system. We interviewed 190 key informants to particularise the AOD treatment sector, and undertook two case examples of government funded non-government organisations providing AOD treatment. Funding sources include the Australian and state and territory governments, philanthropy, fund-raising and clients themselves. While funding sources align with the health sector generally and the broader social services sector, the complexity of flows from source to treatment service and the number of intermediaries are noteworthy. So too are the many sources of funding drawn on by some treatment providers. Diversification is both beneficial and disadvantageous for non-government treatment providers, adding to administrative workloads, but smoothing the risk of funding shortfalls. Government funders benefit from sharing risk. Circuitous funding flows multiply the funding sources drawn on by services and put distance between the funding source and the service provider. This leads to concerns over lack of transparency about what is being purchased and challenges for the multiply funded service provider in maintaining programs and service models amid multiple and sometimes competing funding and accountability frameworks.

    Green water kinematics and dynamics due to wave impingements on a simplified geometry, fixed platform were experimentally investigated in a large, deep-water wave basin. Both plane focusing waves and random waves were employed in the generation of green water. The focusing wave condition was designed to create two consecutive plunging breaking waves with one impinging on the frontal vertical wall of the fixed platform, referred as wall impingement, and the other directly impinging on the deck surface, referred as deck impingement. The random wave condition was generated using the JONSWAP spectrum with a significant wave height approximately equal to the freeboard. A total of 179 green water events were collected in the random wave condition. By examining the green water events in random waves, three different flow types are categorized: collapse of overtopping wave, fall of bulk water, and breaking wave crest. The aerated flow velocity was measured using bubble image velocimetry, while the void fraction was measured using fiber optic reflectometry. For the plane focusing wave condition, measurements of impact pressure were synchronized with the flow velocity and void fraction measurements. The relationship between the peak pressures and the pressure rise times is examined. For the high-intensity impact in the deck impingement events, the peak pressures are observed to be proportional to the aeration levels. The maximum horizontal velocities in the green water events in random waves are well represented by the lognormal distribution. Ritter's solution is shown to quantitatively describe the green water velocity distributions under both the focusing wave condition and the random wave condition. A prediction equation for green water velocity distribution under random waves is proposed.

    Objective: Living organ donation involves interference with a healthy organism. Therefore, most transplantation centres ascertain the voluntariness of the donation as well as its motivation by means of a psychosomatic evaluation. The circumstance that the evaluation is compulsory and not a primary concern of the donor-recipient pair may occasion respondents to present only what they consider innocuous and socially adequate. Thus, the information value of the results can be considerably affected. Methods: In the context of a psychosomatic evaluation prior to living kidney transplantation, 71 donor-recipient pairs were screened at the transplantation centre of Friedrich Schiller University, Jena. Using the validity scales of the Minnesota Multiphasic Personality Inventory (MMPI) (“infrequency” (F), “lie” (L) and “correction-scales” (K)) and the Dissimulation Index according to Gough (“F-K”), we tried to find traits of dissimulation and denial. Results: About 50% of the participants showed an infrequency raw score of zero. This means that at least half of the sample is apprehensive which may cause a cautious and controlled attitude towards the examination. The K-value (T≥59) and the Dissimulation Index (F-K≤–15) indicated dissimulation in 29% and 26% of the overall sample. Moreover, it affects the score of 11 respondents (8%) so profoundly that any significance regarding the personality traits is lost. Conclusion: In the setup of the examination situation as well as in the interpretation of test-psychological findings, the occurrence and possible influence of dissimulation should be considered. The validity scale of the MMPI can help to obtain an objective clinical impression of dissimulation in problem cases. PMID:19911073

    Full Text Available A Ecopedagogia traduz para o campo da Educação as mais importantes discussões realizadas na atualidade sobre questões ambientais. Ecopedagogia, ou pedagogia da terra, ela se afirma como um espaço em que todas as utopias ganham nova forma. Neste artigo nos propomos a discutir o estatuto da Ecopedagogia enquanto espaço da utopia, a partir da análise de suas interfaces com a utopia de Marcuse, do Século XX, e de Schiller, um dos teóricos do Romantismo alemão. Através dessa discussão será possível concluir que existe uma nítida relação entre Ecopedagogia e utopia, mas também entre Ecopedagogia e interesses do capital globalizado e por isso deve ser vista sempre com reservas. The Ecopedagogy translates by the education sphere, the most important discussions done today in what concerns the ecology. Ecopedagogy, or the pedagogy of the Earth, is knew as the space in what all the utopias have their forms. In this text we will analyze the ecopedagogy statute during the space of the utopia, from the analyze of its interfaces with Marcuse’s utopia, of the Century XX, and with the Schiller’s theory, one of the most important philosophy of the German Romanism. Through of this discussion, it will be possible to conclude what it exist a net relation between the Ecopedagogy and the utopia, but also between the Ecopedagogy and the interests of the globalization and, for that, she must be always seen with reserves.

  20. On the moral import of the arts: The case of music.

    2018-01-01

    There has been a controversy on the moral import of music and art in general. On the one hand, the moralist view contends that there is some sort of link between art and morality, even if the way to specify this link may be highly diverse. It comprises most of the classical views of art, from Schiller's view of the role of artistic education in moral development, to any view that declares a form of art as corrupt or degenerated, or enlightening. What it is assumed minimally in all of them is that the moral import of an artwork contributes to its aesthetic value. On the other hand, formalist views claim that the aesthetic value of an artwork is genuine and autonomous, and therefore it is independent of any other value. In this chapter we focus on music, as the most difficult case for the moralist standpoint, given the lack of representational content of music. We argue for a variety of the moralist's view according to which the moral import of a musical artwork is not derived from its content (obviously, as it lack any), but from its pragmatics: the context and the intentions that guide its composition and performance, by analogy with any other intentional action, and point to the emotional impact of music as the common ground that bridges moral and aesthetic values. As a provisional conclusion, we outline a research program for brain studies that follows from this proposal, as a way test its predictions, focusing both on the emotional grounds of valuation and their context-dependency. © 2018 Elsevier B.V.

    In Kolkata city the road transports are maintained by private and Government organization. A major work force belonged to the State Transport Corporation (KSTC), Government of West-Bengal. The pollution caused by these vehicles affects the workers health and caused different types of respiratory problems. This study was undertaken to assess the pulmonary function status of these workers. City KSTC garage workers were investigated and categorically divided into two group: garage mechanics and the (2) those transporting the passengers (drivers and conductors). Vital capacity (VC), forced vital capacity (FVC) and peak expiratory flow rate (PEFR) were recorded by Spirovit-SP-10 (Schiller Ltd, Switzerland) and Wright's Peak Flow Meter (UK) on 236 workers. The different flow volumes, FEV(1), FEV(1%), and flow rates, FEF(02-121), FEF(25-75%), etc. were calculated. The administrative people had higher PFT than the other categories. Drivers and conductors have almost equal mean PFT values but mechanical workers had slightly higher. PFT values according to different age ranges and duration of exposure showed gradual decrement as age and duration of exposure increased. Non-smokers had higher lung volumes compared to smokers and ex-smokers. Restrictive, obstructive and combined types of impairments were noticed in 28.4%, 1.7% and 2.9%, respectively, workers. The restrictive impairment was found to be 30.4% in conductors; 28.9% in drivers, 27.9% in mechanics and 21.7% in administration people. Obstructive type of impairment was found to be 2.9% in both drivers and conductors. The effect of pollution by dust and fumes may be responsible for these pulmonary function impairments, restrictive impairments being greater.

    Wet anaerobic storage of corn stover can provide a year-round supply of feedstock to biorefineries meanwhile serving an active management approach to reduce the risks associated with fire loss and microbial degradation. Wet logistics systems employ particle size reduction early in the supply chain through field-chopping which removes the dependency on drying corn stover prior to baling, expands the harvest window, and diminishes the biorefinery size reduction requirements. Over two harvest years, in-field forage chopping was capable of reducing over 60% of the corn stover to a particle size of 6 mm or less. Aerobic and anaerobic storage methods were evaluated for wet corn stover in 100 L laboratory reactors. Of the methods evaluated, traditional ensiling resulted in <6% total solid dry matter loss (DML), about five times less than the aerobic storage process and slightly less than half that of the anaerobic modified-Ritter pile method. To further demonstrate the effectiveness of the anaerobic storage, a field demonstration was completed with 272 dry tonnes of corn stover; DML averaged <5% after 6 months. Assessment of sugar release as a result of dilute acid or dilute alkaline pretreatment and subsequent enzymatic hydrolysis suggested that when anaerobic conditions were maintained in storage, sugar release was either similar to or greater than as-harvested material depending on the pretreatment chemistry used. This study demonstrates that wet logistics systems offer practical benefits for commercial corn stover supply, including particle size reduction during harvest, stability in storage, and compatibility with biochemical conversion of carbohydrates for biofuel production. Evaluation of the operational efficiencies and costs is suggested to quantify the potential benefits of a fully-wet biomass supply system to a commercial biorefinery. PMID:29632861

    Detailed structural investigations in part of the Leona Valley segment of the San Andreas fault zone, 5-16 km west of Palm dale, focused on the postcrystalline deformation of the block of Mesozoic(?) Pelona Schist underlying Portal and Ritter Ridges. The early fabric of the schist is modified and in places obliterated by cataclasis along shear zones near the San Andreas fault and the Hitchbrook fault, a major west-striking branch of the San Andreas fault system. Anastomosing shear foliations, fabric elements of the postcrystalline deformation, intersect at small angles to one another and are generally vertical or steeply dipping to the north-northeast; they are subparallel to the Hitchbrook fault. Many of these shear foliations are nearly parallel to the compositional layering and schistosity, which commonly dip at moderately steep angles to the northwest. Folds in the shear foliation, commonly intrafolial, generally plunge at moderately steep angles to the north-northeast or are nearly vertical. Other folds, various in form, have axes parallel to the intersections of the early schistosity and the shear foliations and plunge in many other directions. Faults, roughly similar in orientation to the shear foliations, have orientations subparallel to large-scale structures and structural features in the Leona Valley area and in southern California: the San Andreas fault zone in Leona Valley, the Hitchbrook fault, the Garlock fault zone, steep northward-striking faults, the San Andreas fault zone north and south of the Transverse Ranges, and the generally northwest-dipping early compositional layering of the schist. Slickensides on some of the minor faults indicate that the latest movements on the steep faults are predominantly strike slip with indications of less common episodes of predominantly dip slip. The low-angle faults have oblique slip with a large dip component.

  5. What Is the Correct Answer about The Dress' Colors? Investigating the Relation between Optimism, Previous Experience, and Answerability.

    The Dress photograph, first displayed on the internet in 2015, revealed stunning individual differences in color perception. The aim of this study was to investigate if lay-persons believed that the question about The Dress colors was answerable. Past research has found that optimism is related to judgments of how answerable knowledge questions with controversial answers are (Karlsson et al., 2016). Furthermore, familiarity with a question can create a feeling of knowing the answer (Reder and Ritter, 1992). Building on these findings, 186 participants saw the photo of The Dress and were asked about the correct answer to the question about The Dress' colors (" blue and black," "white and gold," "other, namely…," or "there is no correct answer" ). Choice of the alternative "there is no correct answer" was interpreted as believing the question was not answerable. This answer was chosen more often by optimists and by people who reported they had not seen The Dress before. We also found that among participants who had seen The Dress photo before, 19%, perceived The Dress as "white and gold" but believed that the correct answer was "blue and black ." This, in analogy to previous findings about non-believed memories (Scoboria and Pascal, 2016), shows that people sometimes do not believe the colors they have perceived are correct. Our results suggest that individual differences related to optimism and previous experience may contribute to if the judgment of the individual perception of a photograph is enough to serve as a decision basis for valid conclusions about colors. Further research about color judgments under ambiguous circumstances could benefit from separating individual perceptual experience from beliefs about the correct answer to the color question. Including the option "there is no correct answer " may also be beneficial.

  6. Glutamine-dependent carbamoyl-phosphate synthetase and other enzyme activities related to the pyrimidine pathway in spleen of Squalus acanthias (spiny dogfish).

    The first two steps of urea synthesis in liver of marine elasmobranchs involve formation of glutamine from ammonia and of carbamoyl phosphate from glutamine, catalysed by glutamine synthetase and carbamoyl-phosphate synthetase, respectively [Anderson & Casey (1984) J. Biol. Chem. 259, 456-462]; both of these enzymes are localized exclusively in the mitochondrial matrix. The objective of this study was to establish the enzymology of carbamoyl phosphate formation and utilization for pyrimidine nucleotide biosynthesis in Squalus acanthias (spiny dogfish), a representative elasmobranch. Aspartate carbamoyltransferase could not be detected in liver of dogfish. Spleen extracts, however, had glutamine-dependent carbamoyl-phosphate synthetase, aspartate carbamoyltransferase, dihydro-orotase, and glutamine synthetase activities, all localized in the cytosol; dihydro-orotate dehydrogenase, orotate phosphoribosyltransferase, and orotidine-5'-decarboxylase activities were also present. Except for glutamine synthetase, the levels of all activities were very low. The carbamoyl-phosphate synthetase activity is inhibited by UTP and is activated by 5-phosphoribosyl 1-pyrophosphate. The first three enzyme activities of the pyrimidine pathway were eluted in distinctly different positions during gel filtration chromatography under a number of different conditions; although complete proteolysis of inter-domain regions of a multifunctional complex during extraction cannot be excluded, the evidence suggests that in dogfish, in contrast to mammalian species, these three enzymes of the pyrimidine pathway exist as individual polypeptide chains. These results: (1) establish that dogfish express two different glutamine-dependent carbamoyl-phosphate synthetase activities, (2) confirm the report [Smith, Ritter & Campbell (1987) J. Biol. Chem. 262, 198-202] that dogfish express two different glutamine synthetases, and (3) provide indirect evidence that glutamine may not be available in liver for

  7. Chemical aspects of cylinder corrosion and a scenario for hole development

    1991-12-31

    In June 1990, two cylinders in the depleted UF{sub 6} cylinder storage yards at Portsmouth were discovered to have holes in their walls at the valve-end stiffening ring at a point below the level of the gas-solid interface of the UF{sub 6}. The cylinder with the larger hole, which extended under the stiffening ring, was stacked in a top row 13 years ago. The cylinder with the smaller hole had been stacked in a bottom row 4 years ago. The lifting lugs of the adjacent cylinders pointed directly at the holes. A Cylinder Investigating Committee was appointed to determine the cause or causes of the holes and to assess the implications of these findings. This report contains a listing of the chemically related facts established by the Investigating Committee with the cooperation of the Operations and Technical Support Divisions at the Portsmouth Gaseous Diffusion Plant, the scenario developed to explain these findings and some implications of this scenario. In summary, the interrelated reactions of water, solid UF{sub 6} and iron presented by R. L. Ritter are used to develop a scenario which explains the observations and deductions made during the investigation. The chemical processes are intimately related to the course of the last three of the four stages of hole development. A simple model is proposed which permits semiquantitative prediction of such information as the HF loss rates as a function of time, the rate of hole enlargement, the time to hydrolyze a cylinder of UF{sub 6} and the approximate size of the hole. The scenario suggests that the environmental consequences associated with a developing hole in a depleted UF{sub 6} cylinder are minimal for the first several years but will become significant if too many years pass before detection. The overall environmental picture is presented in more detail elsewhere.

    This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). A drug-checking service located at festivals or clubs would be used by 94%; a fixed-site service external to such events by 85%. Most (80%) were willing to wait an hour for their result. Almost all (94%) would not use a service if there was a possibility of arrest, and a majority (64%) would not use a service that did not provide individual feedback of results. Drug-checking results were only slightly more attractive if they provided comprehensive quantitative results compared with qualitative results of key ingredients. Most (93%) were willing to pay up to $5, and 68% up to $10, per test. One-third (33%) reported willingness to donate a whole dose for testing: they were more likely to be male, younger, less experienced, use drugs more frequently and attend venues/festivals less frequently. In this sample, festival- or club-based drug-checking services with low wait times and low cost appear broadly attractive under conditions of legal amnesty and individualised feedback. Quantitative analysis of ecstasy pills requiring surrender of a whole pill may appeal to a minority in Australia where pills are more expensive than elsewhere.

    QRS duration (QRSD) plays a key role in the field of cardiac resynchronization therapy (CRT). Computer-calculated QRSD assessments are widely used, however inter-manufacturer differences have not been investigated in CRT candidates. QRSD was assessed in 377 digitally stored ECGs: 139 narrow QRS, 140 LBBB and 98 ventricular paced ECGs. Manual QRSD was measured as global QRSD, using digital calipers, by two independent observers. Computer-calculated QRSD was assessed by Marquette 12SL (GE Healthcare, Waukesha, WI, USA) and SEMA3 (Schiller, Baar, Switzerland). Inter-manufacturer differences of computer-calculated QRSD assessments vary among different QRS morphologies: narrow QRSD: 4 [2-9] ms (median [IQR]), p=0.010; LBBB QRSD: 7 [2-10] ms, p=0.003 and paced QRSD: 13 [6-18] ms, p=0.007. Interobserver differences of manual QRSD assessments measured: narrow QRSD: 4 [2-6] ms, p=non-significant; LBBB QRSD: 6 [3-12] ms, p=0.006; paced QRSD: 8 [4-18] ms, p=0.001. In LBBB ECGs, intraclass correlation coefficients (ICCs) were comparable for inter-manufacturer and interobserver agreement (ICC 0.830 versus 0.837). When assessing paced QRSD, manual measurements showed higher ICC compared to inter-manufacturer agreement (ICC 0.902 versus 0.776). Using guideline cutoffs of 130ms, up to 15% of the LBBB ECGs would be misclassified as <130ms or ≥130ms by at least one method. Using a cutoff of 150ms, this number increases to 33% of ECGs being misclassified. However, by combining LBBB-morphology and QRSD, the number of misclassified ECGs can be decreased by half. Inter-manufacturer differences in computer-calculated QRSD assessments are significant and may compromise adequate selection of individual CRT candidates when using QRSD as sole parameter. Paced QRSD should preferentially be assessed by manual QRSD measurements. Copyright © 2017 Elsevier B.V. All rights reserved.

Based on the current landscape of clinical trials, guideline recommendations remain inconclusive. The present review discusses the latest evidence derived from studies available in 2013 and investigates optimal blood pressure (BP and preferred treatment substances. Three common archetypes are discussed that hamper the treatment of hypertension in the very elderly. In addition, this paper presents the current recommendations of the NICE 2011, JNC7 2013-update, ESH/ESC 2013, CHEP 2013, JNC8 and ASH/ISH guidelines for elderly patients. Advantages of the six main substance classes, namely diuretics, beta-blockers (BBs, calcium channel blockers (CCBs, angiotensin-converting enzyme inhibitors (ACEIs, angiotensin receptor blockers (ARBs, and direct renin inhibitors (DRIs are discussed. Medical and economic implications of drug administration in the very elderly are presented. Avoidance of treatment-related adverse effects has become increasingly relevant. Current substance classes are equally effective, with similar effects on cardiovascular outcomes. Selection of substances should therefore also be based on collateral advantages of drugs that extend beyond BP reduction. The combination of ACEIs and diuretics appears to be favorable in managing systolic/diastolic hypertension. Diuretics are a preferred and cheap combination drug, and the combination with CCBs is recommended for patients with isolated systolic hypertension. ACEIs and CCBs are favorable for patients with dementia, while CCBs and ARBs imply substantial cost

    Aims: The transiting hot-Jupiter planet Qatar-1 b exhibits variations in transit times that could be perturbative. A hot Jupiter with a planetary companion on a nearby orbit would constitute an unprecedented planetary configuration, which is important for theories of the formation and evolution of planetary systems. We performed a photometric follow-up campaign to confirm or refute transit timing variations. Methods: We extend the baseline of transit observations by acquiring 18 new transit light curves acquired with 0.6-2.0 m telescopes. These photometric time series, together with data available in the literature, were analyzed in a homogenous way to derive reliable transit parameters and their uncertainties. Results: We show that the dataset of transit times is consistent with a linear ephemeris leaving no hint of any periodic variations with a range of 1 min. We find no compelling evidence of a close-in planetary companion to Qatar-1 b. This finding is in line with a paradigm that hot Jupiters are not components of compact multiplanetary systems. Based on dynamical simulations, we place tighter constraints on the mass of any fictitious nearby planet in the system. Furthermore, new transit light curves allowed us to redetermine system parameters with better precision than reported in previous studies. Our values generally agree with previous determinations.

    The Abbe School of Photonics (ASP) provides and coordinates the optics and photonics education of graduate and doctoral students at the Friedrich Schiller University in Jena, Germany. The internationalized Master's degree program is the key activity in training students in the optical sciences. The program is designed to provide them with the skills necessary to fill challenging positions in industry and academia. Here, an essential factor is ASP's close collaboration with more than 20 German photonics companies. To sustain these partners' future economic development, the availability of highly qualified employees is constantly required. Accordingly, these industrial partners, the European Union, the local state and the federal German government are strongly involved in the sustainable development of ASP's curriculum by both conceptual and financial engagements. The main goal is to promote the students' academic careers and job experience in the photonics industry as well as in academia. To open up the program to students from all over the world, all ASP lectures and courses are taught in English. ASP's qualification strategy is fully research-oriented and based on the principles of academic freedom, competitive research conditions and internationalization at all levels. The education program is complemented by a structured doctoral student support and a prestigious guest professorship program. Recently, ASP and partners have started a project to build an open photonics laboratory in order to foster innovative and co-creative processes. The idea follows well-established open innovation schemes e.g. in electronics. This Photon Garage (German: "Lichtwerkstatt") will bring together professionals and interested laymen from different backgrounds to approach pertinent challenges in photonics. Here, we will share our latest insights into the potentials and opportunities offered by this novel educative approach.

SAM motion perception can be described by a psychometric function of the dot aspect ratio ("AR", i.e. the relation between vertical and horizontal dot distances. Further, with equal horizontal and vertical dot distances (AR = 1 perception is biased towards vertical motion. In a series of five experiments, we presented tactile SAM versions and studied the role of AR and of different reference frames for the perception of tactile apparent motion.We presented tactile SAM stimuli and varied the ARs, while participants reported the perceived motion directions. Pairs of vibration stimulators were attached to the participants' forearms and stimulator distances were varied within and between forearms. We compared straight and rotated forearm conditions with each other in order to disentangle the roles of exogenous and endogenous reference frames.Increasing the tactile SAM's AR biased perception towards vertical motion, but the effect was weak compared to the visual modality. We found no horizontal disambiguation, even for very small tactile ARs. A forearm rotation by 90° kept the vertical bias, even though it was now coupled with small ARs. A 45° rotation condition with crossed forearms, however, evoked a strong horizontal motion bias.Existing approaches to explain the visual SAM bias fail to explain the current tactile results. Particularly puzzling is the strong horizontal bias in the crossed-forearm conditions. In the case of tactile apparent motion, there seem to be no fixed priority rule for perceptual disambiguation. Rather the weighting of available evidence seems to depend on the degree of stimulus ambiguity, the current situation and on the perceptual strategy of the individual

    Internal friction and modulus are measured in pure Ti at low temperature using an inverted torsion-pendulum at about 1 Hz. The presence of four relaxation peaks P' sub(d)(-140 0 C), P sub(d)(-101 0 C), P' sub(α)(-75 0 C) and P sub(α)(-50 0 C) has been found, and effects of plastic deformation, heat treatment and neutron irradiation on these peaks are investigated in detail. Activation energies and frequency factors of P sub(d) and Pα peaks are consistent with the data in higher frequency range reproted by other workers. The P sub(d) and P' sub(d) peaks grow after deformation and tend to decay after annealing at high temperatures or after neutron irradiation. Both peaks are resonably interpreted in terms of dislocation relaxation mechanisms (Bordoni type) arising from thermally activated motion of dislocations in different slip planes of h.c.f. structure. Peierls stress of dislocations giving rise to each peak have calculated based on Seeger's theory, and found to be consistent with that of f.c.c. metals. On the other hand, P sub(α) and P' sub(α) peaks grow significantly at the expense of P sub(d) and P' sub(d) peaks after neutron irradiation in deformed samples. The behaviour of these peaks as a function of irradiation dose and annealing temperatures strongly indicated that they are due to relaxations resulting from dislocations-point defects interactions (Hasiguti type). It is tentatively suggested that P sub(α) and P' sub(α) peaks are related with interactions of dislocations with divacancies and single vacancies, respectively. Application of Schiller's model showed a consistent result with regard to the P' sub(α) peak experimentally observed. (Author) [pt

    The mechanical properties of cells are considered promising biomarkers for the early diagnosis of cancer. Recently, atomic force microscopy (AFM)-based nanoindentation technology has been utilized for the examination of cell cortex mechanics in order to distinguish malignant cells from normal cells. However, few attempts to evaluate the biomechanical properties of cells have focused on the quantification of the non-homogeneous longitudinal elasticity of cellular structures. In the present study, we applied a variation of the method of Carl and Schillers to investigate the differences between longitudinal elasticity of human cervical squamous carcinoma cells (CaSki) and normal cervical epithelial cells (CRL2614) using AFM. The results reveal a three-layer heterogeneous structure in the probing volume of both cell types studied. CaSki cells exhibited a lower whole-cell stiffness and a softer nuclei zone compared to the normal counterpart cells. Moreover, a better differentiated cytoskeleton was found in the inner cytoplasm/nuclei zone of the normal CRL2614 cells, whereas a deeper cytoskeletal distribution was observed in the probing volume of the cancerous counterparts. The sensitive cortical panel of CaSki cells, with a modulus of 0.35~0.47 kPa, was located at 237~225 nm; in normal cells, the elasticity was 1.20~1.32 kPa at 113~128 nm. The present improved method may be validated using the conventional Hertz-Sneddon method, which is widely reported in the literature. In conclusion, our results enable the quantification of the heterogeneous longitudinal elasticity of cancer cells, in particular the correlation with the corresponding depth. Preliminary results indicate that our method may potentially be applied to improve the detection of cancerous cells and provide insights into the pathophysiology of the disease.

  17. SGLT2 inhibitors – an insulin-independent therapeutic approach for treatment of type 2 diabetes: focus on canagliflozin

    Full Text Available Jochen SeufertDepartment of Endocrinology and Diabetology, Clinic for Internal Medicine II, Freiburg University Hospital, Freiburg, GermanyAbstract: Despite the availability of a great variety of medications, a significant proportion of people with type 2 diabetes mellitus (T2DM are not able to achieve or maintain adequate glycemic control. Beyond improved glucose control, novel treatments would ideally provide a reduction of cardiovascular risk, with a favorable impact on excess weight, and a low intrinsic hypoglycemia risk, as well as a synergistic mechanism of action for broad combination therapy. With the development of sodium glucose cotransporter 2 (SGLT2 inhibitors, an antidiabetic pharmacologic option has recently become available that comes close to meeting these requirements. For the first time, SGLT2 inhibitors offer a therapeutic approach acting directly on the kidneys without requiring insulin secretion or action. Canagliflozin, dapagliflozin, and empagliflozin are the SGLT2 inhibitors approved to date. Taken once a day, these medications can be combined with all other antidiabetic medications including insulin, due to their insulin-independent mechanism of action, with only a minimal risk of hypoglycemia. SGLT2 inhibitors provide additional reductions in body weight and blood pressure due to the therapeutically induced excretion of glucose and sodium through the kidneys. These "concomitant effects" are particularly interesting with regard to the increased cardiovascular risk in T2DM. In many cases, T2DM treatment requires a multidimensional approach where the treatment goals have to be adapted to the individual patient. While there is a consensus on the use of metformin as a first-line drug therapy, various antidiabetics are used for treatment intensification. New mechanisms of action like that of SGLT2 inhibitors such as canagliflozin, which can be used both in early and late stages of diabetes, are a welcome addition to expand

However, its intraoperative administration can lead to increased postoperative analgesic requirements, which is postulated to be the result of acute opioid tolerance with enhancement of spinal N-methyl-D-aspartate receptor function. Although strategies to prevent or reduce tolerance have included the coadministration of longer acting opioids or ketamine, the majority of these studies have demonstrated little to no benefit. The current study retrospectively evaluates the efficacy of intrathecal morphine (ITM in preventing hyperalgesia following a remifentanil infusion.Methods: We retrospectively analyzed 54 patients undergoing posterior spinal fusion with segmental spinal instrumentation, to evaluate the effects of ITM on hyperalgesia from remifentanil. Patients were divided into two groups based on whether they did or did not receive remifentanil during the surgery: no remifentanil (control group (n=27 and remifentanil (study group (n=27. Data included demographics, remifentanil dose and duration, Wong–Baker visual analog scale postoperative pain scores, and postoperative intravenous morphine consumption in the first 48 postoperative hours.Results: The demographics of the two study groups were similar. There were no differences in the Wong–Baker visual analog

    A more rigorous cyclic adsorption process simulator is being developed for use in the development and understanding of new and existing PSA processes. Unique features of this new version of the simulator that Ritter and co-workers have been developing for the past decade or so include: multiple absorbent layers in each bed, pressure drop in the column, valves for entering and exiting flows and predicting real-time pressurization and depressurization rates, ability to account for choked flow conditions, ability to pressurize and depressurize simultaneously from both ends of the columns, ability to equalize between multiple pairs of columns, ability to equalize simultaneously from both ends of pairs of columns, and ability to handle very large pressure ratios and hence velocities associated with deep vacuum systems. These changes to the simulator now provide for unique opportunities to study the effects of novel pressure changing steps and extreme process conditions on the performance of virtually any commercial or developmental PSA process. This presentation will provide an overview of the cyclic adsorption process simulator equations and algorithms used in the new adaptation. It will focus primarily on the novel pressure changing steps and their effects on the performance of a PSA system that epitomizes the extremes of PSA process design and operation. This PSA process is a sorbent-based atmosphere revitalization (SBAR) system that NASA is developing for new manned exploration vehicles. This SBAR system consists of a 2-bed 3-step 3-layer system that operates between atmospheric pressure and the vacuum of space, evacuates from both ends of the column simultaneously, experiences choked flow conditions during pressure changing steps, and experiences a continuously changing feed composition, as it removes metabolic CO2 and H20 from a closed and fixed volume, i.e., the spacecraft cabin. Important process performance indicators of this SBAR system are size, and the

    The health care industry is an information-dependent business that will require a new generation of health information systems if successful health care reform is to occur. We critically need integrated clinical management information systems to support the physician and related clinicians at the direct care level, which in turn will have linkages with secondary users of health information such as health payors, regulators, and researchers. The economic dependence of health care industry on the CPR cannot be underestimated, says Jeffrey Ritter. He sees the U.S. health industry as about to enter a bold new age where our records are electronic, our computers are interconnected, and our money is nothing but pulses running across the telephone lines. Hence the United States is now in an age of electronic commerce. Clinical systems reform must begin with the community-based patient chart, which is located in the physician's office, the hospital, and other related health care provider offices. A community-based CPR and CPR system that integrates all providers within a managed care network is the most logical step since all health information begins with the creation of a patient record. Once a community-based CPR system is in place, the physician and his or her clinical associates will have a common patient record upon which all direct providers have access to input and record patient information. Once a community-level CPR system is in place with a community provider network, each physician will have available health information and data processing capability that will finally provide real savings in professional time and effort. Lost patient charts will no longer be a problem. Data input and storage of health information would occur electronically via transcripted text, voice, and document imaging. All electronic clinical information, voice, and graphics could be recalled at any time and transmitted to any terminal location within the health provider network. Hence

  3. The Leadville Mine Drainage Tunnel Catastrophe: A Case Study of How Isotope Geochemistry Provided Forensic Evidence to Inform Policy Decisions

    A state of emergency was declared in February 2008 because of fears that a blocked drainage tunnel in the Leadville mining district of Colorado could cause a catastrophic flood. An estimated 1 billion gallons of metals-laden water poses an eminent threat to the city of Leadville and the headwaters of the Arkansas river. Within days of the declaration of a state of emergency, Governor Ritter and Senator Salazer of Colorado, along with a host of other local and statewide politicians, visited the site and emphasized the need to develop a fast yet safe mitigation plan. Here we provide information from a case study that illustrates how a suite of isotopic and hydrologic tools enables identification of critical, site-specific variables essential in developing a science plan to guide targeted remediation of the Leadville drainage tunnel. The isotopic tools, including both stable and radiogenic isotopes, provided clear and compelling evidence of water sources and flowpaths in an area that has undergone extensive perturbations, including the drilling of more than 2,000 mine shafts. This forensic evidence was the key information in developing a plan to plug the drainage tunnel several hundred feet underground, divert a major source of polluted water from reaching the collapsed tunnel and piping it to an existing treatment plant, and guidance on where to place pumps in additional mine shafts, and the drilling of new wells to pump water in case the plugging of the tunnel caused water to pool up and raise the water table to dangerous heights. This particular case of forensic hydrology using isotopic tools not only provides the scientific basis for an operational plan to defuse a life- and property-threatening situation, it also provides the basis for decommissioning an existing water treatment plant, which will result in savings of over 1 million annually in operational costs. Decommissioning the existing water treatment plant will pay for the tunnel mitigation within several

    Full Text Available Erzählungen können absichtlich die Unwahrheit verbreiten. Ob der Autor bzw. die Autorin selbst der Lüge bezichtigt werden kann oder sollte, hängt allerdings nicht nur davon ab, wie man Lüge definiert, sondern auch davon, welchen Status man der Erzählung zuschreibt: Worin unterscheidet sich der Wahrheitsanspruch fiktionaler Äußerungen in literarischen Texten von dem faktualen Erzählens? Kann Fiktion lügen? Eva-Maria Konrad plädiert nach einer Auseinandersetzung mit Genettes Studie zu Paratexten dafür, vom Autor verantwortete Vorworte in literarischen Texten nicht generell als fiktionale Äußerungen zu betrachten – unter bestimmten Voraussetzungen, so Konrad, könnten daher auch Herausgeberfiktionen als Lügen bezeichnet werden. Jochen Mecke hingegen argumentiert, dass fiktionale Literatur nie lügen kann, da jede Zuschreibung von Aufrichtigkeit an literarische Texte auf jenem Pakt zwischen Leser(in und Autor(in basiert, den Samuel Taylor Coleridge als „willing suspension of disbelief“ bezeichnet hat. Entscheidend ist dabei, so Mecke, nicht die Fiktivität der erzählten Ereignisse, sondern die Fiktionalität der Aussageinstanz. Sabine Schlickers untersucht in ihrem Beitrag zum unzuverlässigen und verstörenden Erzählen im argentinischen Kino, wie Ambiguität entsteht – der zeitgenössische Film macht es dem Publikum häufig schwer, dem impliziten Autor eine eindeutige Intention, sei es Ironie, Spiel oder Lüge, zuzuschreiben.

However, complications associated with mesh implantation, such as mesh-related infections, can cause serious problems and may require complete surgical removal. Hence, the aim of the present study was the development of a safe and efficient coating to reduce postoperative mesh infections. Biodegradable poly(lactide-co-glycolide acid microspheres loaded with rifampicin as an antibacterial agent were prepared through single emulsion evaporation method. The particle size distribution (67.93±3.39 µm for rifampicin-loaded microspheres and 64.43±3.61 µm for unloaded microspheres was measured by laser diffraction. Furthermore, the encapsulation efficiency of rifampicin (61.5%±2.58% was detected via ultraviolet–visible (UV/Vis spectroscopy. The drug release of rifampicin-loaded microspheres was detected by UV/Vis spectroscopy over a period of 60 days. After 60 days, 92.40%±3.54% of the encapsulated rifampicin has been continuously released. The viability of BJ fibroblasts after incubation with unloaded and rifampicin-loaded microspheres was investigated using an MTT (3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay, which showed no adverse effects on the cells.

    Full Text Available The problem of human staphylococcal infection in the world has been considered. It is known that there are 27 species of staphylococci, 14 of them colonize the skin and mucous membranes of humans, and 3 of them may cause diseases. They are Staphylococcus aureus, S. epidermidis and S. saprophyticus. Staphylococci are causative agents of the large part of community-acquired and nosocomial bacteremia, pneumonia, infections of skin and soft tissues, bones and joints. Of all cases of nosocomial infections, S. aureus accounts for 31%. During the identification of 65 strains of bacteria isolated from people with respiratory tract lesions, it was found that 58.5% of cases were connected with presence of staphylococci. 86.8% of isolates identified belong to species S. aureus and 13.2% to S. saprophyticus. Study of pathogenicity factors manifestation revealed that all strains identified as S. aureus had plasmocoagulase; lipase and lecitinase were simultaneously detected in 78.3% of them, among S. saprophyticus strains in 20%. Presence of haemolysins was determined for 82.1% of strains of staphylococci. Ability to film formation was detected in 21 (63.6% strains of S. aureus and 2 (40% of S. saprophyticus strains. Given high frequency of carriers of staphylococci among healthy individuals, they should be considered as potentially pathogenic microorganisms and opportunistic pathogens. Due to their pathogenicity factors (adhesins, capsule, cell wall components, enzymes and toxins, staphylococci may cause diseases such as sepsis, meningitis, peritonitis, endocarditis, pneumonia, tonsillitis, and in young children they may result in serious Ritter illness (“babies scalded syndrome”, foodstuff infection and staphylococcal enterocolitis, in lactating women – mastitis, toxic shock syndrome.

In combination with active ingredients, a specialized drug delivery system can be generated. The aim of the present study was to develop a drug delivery system consisting of PLGA microspheres loaded with the natural active ingredient totarol, which has several antimicrobial mechanisms. Totarol, isolated from the Podocarpus totara tree, was purified using column chromatography, and the eluate was checked for purity using thin layer chromatography. The spherically shaped microspheres with mean diameters of 147.21±3.45 µm and 131.14±3.69 µm (totarol-loaded and -unloaded microspheres, respectively were created using the single emulsion evaporation method. Furthermore, the encapsulation efficiency, in a range of 84.72%±6.68% to 92.36%±0.99%, was measured via UV/vis spectroscopy. In a 90-day in vitro drug release study, the release of totarol was investigated by UV/vis spectroscopy as well, showing a release of 53.76%. The toxicity on cells was determined using BJ fibroblasts or Human Embryonic Kidney cells and an 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay, which showed no influence on the cell growth. The minimal inhibitory concentration was ascertained. A totarol concentration between 64 µg/mL and 128 µg/mL was necessary to inhibit the bacterial growth over a period of 24 hours.

    The bubble regime of laser-wakefield acceleration has been studied over the recent years as an important alternative to classical accelerators. Several models and theories have been published, in particular a theory which provides scaling laws for acceleration parameters such as energy gain and acceleration length. This thesis deals with numerical simulations within the bubble regime, their comparison to these scaling laws and data obtained from experiments, as well as some specific phenomenona. With a comparison of the scaling laws with numerical results a parameter scan was able to show a large parameter space in which simulation and theory agree. An investigation of the limits of this parameter space revealed boundaries to other regimes, especially at very high (a{sub 0} > 100) and very low laser amplitudes (a{sub 0} < 4). Comparing simulation data with data from experiments concerning laser pulse development and electron energies, it was found that experimental results can be adequately reproduced using the Virtual-Laser-Plasma-Laboratory code. In collaboration with the Institut fuer Optik und Quantenelektronik at the Friedrich-Schiller University Jena synchrotron radiation emitted from the inside of the bubble was investigated. A simulation of the movement of the electrons inside the bubble together with time dependent histograms of the emitted radiation helped to prove that the majority of radiation created during a bubble acceleration originates from the inside of the bubble. This radiation can be used to diagnose the amplitude of oscillation of the trapped electrons. During a further study it was proven that the polarisation of synchrotron radiation from a bubble contains information about the exact oscillation direction. This oscillation was successfully controlled by using either a laser pulse with a tilted pulse front or an asymmetric laser pulse. First results of ongoing studies concerning injecting electrons into an existing bubble and a scheme called

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

    Science.gov (United States)

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

    Since the 1970s, radar remote sensing techniques have evolved rapidly and are increasingly employed in all fields of earth sciences. Applications are manifold and still expanding due to the continuous development of new instruments and missions as well as the availability of very high-quality data. The trend worldwide is towards operational employment of the various algorithms and methods that have been developed. However, the utilization of operational services does not keep up yet with the rate of technical developments and the improvements in sensor technology. With the enhancing availability and variety of space borne Synthetic Aperture Radar (SAR) data and a growing number of analysis algorithms the need for a vital user community is increasing. Therefore the German Aerospace Center (DLR) together with the Friedrich-Schiller-University Jena (FSU) and the Technical University Munich (TUM) launched the education initiative SAR-EDU. The aim of the project is to facilitate access to expert knowledge in the scientific field of radar remote sensing. Within this effort a web portal will be created to provide seminar material on SAR basics, methods and applications to support both, lecturers and students. The overall intension of the project SAR-EDU is to provide seminar material for higher education in radar remote sensing covering the topic holistically from the very basics to the most advanced methods and applications that are available. The principles of processing and interpreting SAR data are going to be taught using test data sets and open-source as well as commercial software packages. The material that is provided by SAR-EDU will be accessible at no charge from a DLR web portal. The educational tool will have a modular structure, consisting of separate modules that broach the issue of a particular topic. The aim of the implementation of SAR-EDU as application-oriented radar remote sensing educational tool is to advocate the development and wider use of

    It has been shown that the functionality of the macula lutea depends on the nutritional uptake of lutein and zeaxanthin and that it is inversely associated with the risk of age-related macular degeneration (AMD). Additionally, ω-3 long-chain polyunsaturated fatty acids (LC-PUFAs) may also be protective. To investigate the effect of a 12-month intervention with macular xanthophylls and ω-3 LC-PUFAs on xanthophylls and fatty acids in plasma, antioxidant capacity, and optical density of the macular pigment of patients with nonexudative AMD. The LUTEGA study was a randomized, double-blind, placebo-controlled, parallel clinical trial that was conducted for 12 months. University Eye Hospital and Institute of Nutrition, Friedrich Schiller University Jena, Germany. A total of 172 individuals with nonexudative AMD. Individuals were enrolled and randomly divided as follows: placebo group, group 1 (a capsule containing 10 mg of lutein, 1 mg of zeaxanthin, 100 mg of docosahexaenoic acid, and 30 mg of eicosapentaenoic acid administered each day), and group 2 (same substances but twice the dose used in group 1). One hundred forty-five participants completed the study successfully. Plasma xanthophyll concentrations and fatty acid profiles, optical density of the macular pigment, and antioxidant capacity in plasma (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid [Trolox] equivalent antioxidant capacity and photochemiluminescence). The concentrations of the administered carotenoids in plasma as well as the optical density of the macular pigment increased significantly in the groups randomized to receive supplementary macular xanthophylls and ω-3 LC-PUFAs after 1 month of intervention and remained at this level through the end of the study. Use of the double dose resulted in a beneficial alteration of the fatty acid profile in the plasma of patients with AMD in comparison with the dose in group 1. The lipophilic antioxidant capacity in plasma was significantly elevated

  2. Polypharmacy or medication washout: an old tool revisited

Even the new generation of medications may not hold significant advantages over older drugs. In fact, there may be additional safety risks with polypharmacy being so widespread. Washout, as a clinical tool, is rarely done in medication management today. Studies have shown that augmenting therapy with additional medications resulted in 9.1%–34.1% dropouts due to intolerance of the augmentation, whereas studies of medication washout demonstrated only 5.9%–7.8% intolerance to the washout procedure. These perils justify reconsideration of medication washout before deciding on augmentation. There are unwarranted fears and resistance in the medical community toward medication washout, especially at the moment a physician is trying to decide whether to washout or add more medications to the treatment regimen. However, medication washout provides unique benefits to the physician: it establishes a new baseline of the disorder, helps identify medication efficacy from their adverse effects, and provides clarity of diagnosis and potential reduction of drug treatments, drug interactions, and costs. It may also reduce overall adverse events, not to mention a potential to reduce liability. After washout, physicians may be able to select the appropriate

    Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

Based on these findings, various actions are recommended for development, usability, effectiveness and cost-effectiveness, deployment, and ethics of assistive and health technologies across Europe. These include avoiding replication of technology development that is unhelpful or ineffective and focusing on how technologies succeed in addressing individual needs of persons with dementia. Furthermore, it is suggested to include these recommendations in national and international calls for funding and assistive technology research programs. Finally, practitioners, policy makers, care insurers, and care providers should work together with technology enterprises and researchers to prepare strategies for the implementation of assistive technologies in different care settings. This may help future generations of persons with dementia to utilize available and affordable technologies and, ultimately, to benefit from them. ©Franka Meiland, Anthea Innes, Gail Mountain, Louise Robinson, Henriëtte van der Roest, J Antonio García-Casal, Dianne Gove, Jochen René Thyrian, Shirley Evans, Rose-Marie Dröes, Fiona Kelly, Alexander Kurz, Dympna Casey, Dorota Szcześniak, Tom Dening, Michael P Craven, Marijke Span, Heike Felzmann, Magda Tsolaki, Manuel Franco-Martin.

    The International Conference on Highly Frustrated Magnetism 2008 (HFM2008) took place on 7-12 September 2008 at the Technische Universität Carolo-Wilhelmina zu Braunschweig, Germany. This conference was the fourth event in a series of meetings, which started in Waterloo, Canada (HFM 2000), followed by the second one in Grenoble, France (HFM 2003), and the third meeting in Osaka, Japan (HFM 2006). HFM2008 attracted more than 220 participants from all over the world. The number of participants of the HFM conference series has been increasing steadily, from about 80 participants at HFM 2000, to 120 participants at HFM 2003, and 190 participants at HFM 2006, demonstrating that highly frustrated magnetism remains a rapidly growing area of research in condensed matter physics. At the end of HFM2008 it was decided that the next International Conference on Highly Frustrated Magnetism will be held in Baltimore, USA in 2010. HFM2008 saw four plenary talks by R Moessner, S Nakatsuji, S-W Cheong, and S Sachdev, 18 invited presentations, 30 contributed talks and about 160 poster presentations from all areas of frustrated magnetism. The subjects covered by the conference included: Kagome systems Itinerant frustrated systems Spinels and pyrochlore materials Triangular systems Unconventional order and spin liquids Chain systems Chain systems Novel frustrated systems This volume of Journal of Physics: Conference Series contains the proceedings of HFM2008 with 83 papers that provide a scientific record of the scientific topics covered by the conference.

    Full Text Available Problematic internet use (PIU is considered as a relatively new area of risk taking behaviour, which deals with uncontrolled use of the Internet with negative outcomes (impact on individuals (Caplan, 2010. This paper focuses on relationship between personality factors, depression and problematic internet use among students of secondary schools and universities in Ostrava region. The aim of the paper was to determine whether personality factors and depression predict problematic internet use among young students. Studies dealing with problematic internet use (Caplan, 2010; Young 1998; Davis, 2001 etc. show that personality is one of the factor which may be associated with internet addiction or other forms of risk behaviour (Kolibáš, Novotný, 1996; Kopasová, 2000; Hemochová, Vaňková & Drlíková in Výrost & Slameník, 2001. Personality was measured by the questionnaire HEXACO (Ashton & Lee, 2009, depression was measured by a modified version of Beck Depression Inventory (M-BDI; Schmitt, Beckmann, Dusi, Maes, Schiller &Schonauer, 2003, the problematic internet use was measured by Generalized problematic internet use scale (GPIUS2; Caplan, 2010. The research sample consisted of 279 students of secondary schools and universities in Ostrava region. There were 200 (71.7% high school students while the number of the university students was 79 (28.3%. The mean age of the sample was M = 18,5 years, SD = 2,73 and 79,9% were women. The results of Pearson correlation coefficients showed a positive relationship between depression, emotionality and PIU. Between the personality factors honesty-humility, extroversion and conscientiousness was a negative relationship with the PIU. Results of the regression analysis showed four factors - conscientiousness, depression, honesty-humility and emotions that explain 26% of the variance of the Problematic internet use among our research sample. The results confirm the importance of examining personality factors

    element compositions imply. Many trace element analyses are performed using either bulk rock techniques or spot analyses, and these maps suggest those types of analyses likely sample variable trace element abundances even within otherwise homogeneous grains, rendering their results difficult to interpret. Consequently, the correlation discussed previously between trace elements and short lived isotopes has likely been impacted by post-magmatic alteration and cannot solely be used to argue that HED's cannot be derived from Vesta. Furthermore, these maps strengthen the HED-Vesta link by suggesting that the diogenites underwent an extended history of cooling, reheating, partial melting, impact fragmentation, fluid/melt migration, and finally re-annealing. These complicated steps are particularly noteworthy as the pyroxene cumulate layer on the asteroid Vesta should lie beneath the eucritic crust, implying that early impacts were able to penetrate that crust and affect the diogenite layers early in Vesta's history, most likely while the asteroid was still hot enough to allow for annealing and regrowth of fractured grains.

    Full Text Available One of the leading pathogenic mechanisms of chronic catarrhal gingivitis development in children is disorders in the system of child macroorganism and oral cavity microorganisms interrelation as a result of normal microflora inhibition against the background of general amount of opportunistic and pathogenic microorganisms. The oral cavity protective mechanisms condition plays an important role in this process. Due to this fact a perspective direction is to study the methods of mentioned pathology treatment using probiotics containing strains of normal microflora with high antagonistic, enzymatic and immune-modeling properties able to inhibit growth of pathogenic bacteria. Objective: to improve the common method of catarrhal gingivitis treatment in children by means of oral microbiocenosis correction on the local level. Materials and methods. The method of catarrhal gingivitis treatment in children with administration of the probiotic “BioGaia Prodentis” has been developed. 30 children at the age of 12 with clinical signs of chronic catarrhal gingivitis were treated and dynamically observed. The children were divided into two groups: the main (with application of the improved method and the group of comparison (the common method was applied. The periodontal tissue condition in children was assessed on the basis of OHI-S, PMA, CPI indices, and Schiller-Pisaref test. The oral cavity local immunity was assessed by means of lysozyme activity, the level of secretory immunoglobulin A, the degree of dysbiosis by urease activity detection in the oral fluid of children. Results. Administration of the drug “BioGaia Prodentis” in the complex of chronic catarrhal gingivitis treatment in children resulted in a quick reverse development of clinical signs. Among the children of the main group on the 3–4th day of treatment a tendency to subsidence of inflammatory signs was observed. In the group of comparison the signs such as hyperemia, swelling and

    GMES Initial Operations - Network for Earth Observation Research Training (GIONET) is a Marie Curie funded project that aims to establish the first of a kind European Centre of Excellence for Earth Observation Research Training. Copernicus (previously known as GMES (Global Monitoring for Environment and Security) is a joint undertaking of the European Space Agency and the European Commission. It develops fully operational Earth Observation monitoring services for a community of end users from the public and private sector. The first services that are considered fully operational are the land monitoring and emergency monitoring core services. In GIONET, 14 early stage researchers are being trained at PhD level in understanding the complex physical processes that determine how electromagnetic radiation interacts with the atmosphere and the land surface ultimately form the signal received by a satellite. In order to achieve this, the researchers are based in industry and universities across Europe, as well as receiving the best technical training and scientific education. The training programme through supervised research focuses on 14 research topics. Each topic is carried out by an Early Stage Researcher based in one of the partner organisations and is expected to lead to a PhD degree. The 14 topics are grouped in 5 research themes: Forest monitoring Land cover and change Coastal zone and freshwater monitoring Geohazards and emergency response Climate adaptation and emergency response The methods developed and used in GIONET are as diverse as its research topics. GIONET has already held two summer schools; one at Friedrich Schiller University in Jena (Germany), on 'New operational radar satellite applications: Introduction to SAR, Interferometry and Polarimetry for Land Surface Mapping'. The 2nd summer school took place last September at the University of Leicester (UK )on 'Remote sensing of land cover and forest in GMES'. The next Summer School in September 2013

    Full Text Available In 1909, the 19th of December, the Roman-Catholic Archbishop of Bucharest, Raymund Netzhammer, a Benedictine monk from the German abbey Einsiedeln, consecrated the Greek-Catholic church in Bucharest dedicated to St Basil the Great. As he wanted to have a church in the Romanian architectural style, he asked the architect Nicolae Ghika-Budeşti to design the project. It was inspired by the medieval Moldavian churches, with a lantern-tower above the nave, apparent brick façades and an outside decoration with enameled ceramic discs. The archbishop intention was to realize a synthesis between Romanian art and the Occidental one. So he decided to invite painters from the well-known in the Benedictine media Beuron School of Art, initiated by Petrus (Desiderius, as monk and Gabriel/Jakob Wüger from the abbey with the same name. The project for the inside murals was done by father Andreas Göser, who worked in the great Monte-Cassino abbey (Italy, the mother monastery of the Benedictine Order, too, and achieved by two painters from Ravensburg, Schiller and Ostermaier, who signed the cartoons, whose originals are kept in negatives on glass in the Einsiedeln abbey. Paintings were done in the pure Beuron style. The Christ Pantocrator (The Almighty was painted on the cupola of the tower, surrounded by Angels. The Virgin with Jesus Infant venerated by Angels occupied the semi-cupola of the chancel, as usually in the Oriental churches, and great archangels stood on the intrados of the triumphal arch. Four episodes from Saint Basil’s Life (Baptism, Ordination as a priest, St Basil is giving alms to the poor; St Basil is healing the emperor’s son were painted on the great surfaces below the arches of the nave. Christ as High Priest was to be found on the Western cupola. On the Western wall, in the Votive picture, the founder, archbishop Raymund Netzhammer, kneeled, dressed in simple Benedictine cassock, and offered the model of the church to St. Basil. As

    Terrain modeling, the practice of ground-surface quantification, is an amalgam of Earth science, mathematics, engineering, and computer science. The discipline is known variously as geomorphometry (or simply morphometry), terrain analysis, and quantitative geomorphology. It continues to grow through myriad applications to hydrology, geohazards mapping, tectonics, sea-floor and planetary exploration, and other fields. Dating nominally to the co-founders of academic geography, Alexander von Humboldt (1808, 1817) and Carl Ritter (1826, 1828), the field was revolutionized late in the 20th Century by the computer manipulation of spatial arrays of terrain heights, or digital elevation models (DEMs), which can quantify and portray ground-surface form over large areas (Maune, 2001). Morphometric procedures are implemented routinely by commercial geographic information systems (GIS) as well as specialized software (Harvey and Eash, 1996; Köthe and others, 1996; ESRI, 1997; Drzewiecki et al., 1999; Dikau and Saurer, 1999; Djokic and Maidment, 2000; Wilson and Gallant, 2000; Breuer, 2001; Guth, 2001; Eastman, 2002). The new Earth Surface edition of the Journal of Geophysical Research, specializing in surficial processes, is the latest of many publication venues for terrain modeling. This is the fourth update of a bibliography and introduction to terrain modeling (Pike, 1993, 1995, 1996, 1999) designed to collect the diverse, scattered literature on surface measurement as a resource for the research community. The use of DEMs in science and technology continues to accelerate and diversify (Pike, 2000a). New work appears so frequently that a sampling must suffice to represent the vast literature. This report adds 1636 entries to the 4374 in the four earlier publications1. Forty-eight additional entries correct dead Internet links and other errors found in the prior listings. Chronicling the history of terrain modeling, many entries in this report predate the 1999 supplement

    . In the series of four short contributions, recent experimental results from the HERMES Collaboration are presented. Particularly important are the results on the quark transverse spin polarisation in the nucleon. The Hermes experiments have found evidence of nonvanishing quark transverse polarisation and have provided an indication for a nonzero orbital angular momentum of quarks in the nucleon. - Atomic physics - The L-shell ionisation cross sections for atoms of some heavy elements were measured. The results are presented and compared to different model calculations. - Materials research - Our group of scientists performed many experimental studies using low-energy p-, d- and α- beams from the van de Graaff accelerator of the Department which were commissioned by other institutions. In this Annual Report the results of experiments devoted to studying damage buildup and recovery of compound semiconductors are presented. The experiments were performed at the Friedrich Schiller University of Jena, in collaboration with local scientists. Our involvement in education and science popularization has become a tradition. Students of Warsaw High Schools and of Warsaw University attended in 2004 many lectures given by Dr. Andrzej Korman and Dr. Lech Nowicki on nuclear physics, accelerators, detectors and nuclear methods in solid state physics. Our contribution to the 8 th Scientific Picnic and the 11 th Science Festival is also worth mentioning. (author)

    Henry Darcy was a civil engineer recognized for a number of technical achievements and scientific discoveries. The sand column experiments for which he is known revealed the linear relationship that exists between fluid motion and driving forces at low velocities. Freeze and Back (1983) stated, ''The experiments carried out by Darcy with the help of his assistant, Ritter, in Dijon, France in 1855 and 1856 represent the beginning of groundwater hydrology as a quantitative science." Because of the prominence given to this experiment, two important facts behind Darcy's contributions to subsurface hydrology have not received much attention. First, Darcy was not only a good engineer, but he was also a highly respected scientist whose knowledge of both the fundamentals of fluid mechanics and the natural world of geology led to better conceptualizing and quantifying of groundwater processes at relevant scales to solve practical problems. The experiments for which he is known may have already been conceived, based on his theoretical understanding, and the results were anticipated (Brown 2002). Second, Darcy, through his contributions with Dupuit, showed that they understood hydrologeology at a regional scale and developed methods for quantification at the scale of geologic stratum (Ritz and Bobek, 2008). The primary thesis of this talk is that scientific contributions such as the one Darcy made require appreciation and a thorough understanding of fundamental theory coupled with observation and recording of phenomena both in nature and in the laboratory. Along with all of the significant theoretical, mathematical modeling, and computational advances we have made in the last several decades, laboratory experiments designed to observe phenomena and processes for better insight, accurate data generation, and hypothesis development are critically important to make scientific and engineering advances to address some of the emerging and societally important problems in hydrology

    communication". In a brief presentation of Linhart's life and his literary creativity I shall suggest some reasons for his views on life, religion and philosophy. They can be seen in his translation of Alexander Pope's "Essay on Man" as well as his appreciation of Scottish poetry. The influence of German playwrights belonging to the Sturm and Drang movement (e.g. G. T. Lessing, J. F. Schiller, F. M. Klinger has been frequently discussed by Slovene literary historians, and therefore it is mentioned here only in passing. Slovene critics have often ascribed a very important influence of English playwright George Lillo on Linhart' s tragedy Miss Jenny Love, but its echoes are much less visible than the impact of Shakespeare's great tragedies, particularly in the structure, character presentations and the figurative use of language in Linhart's tragedy. 1shall try to prove this influence in the final part of my study. Because my study is oriented towards British and Slovene readers, 1had to include some facts which may be well-known to one group or to another group of readers. Nevertheless I hope that they will all find in it enough evidence to agree with me that Shakespeare's influence on Linhart's play Miss Jenny Love was rather important.

    -19 September 2007 (President--V. Nesic, Belgrade). The IX BANTAO congress was held in Antalya, 18-22 November 2009 (President--A. Basci, Izmir). The X BANTAO congress was held from 13 to 15 October 2011 in Chalkidiki (President--D. Tsakiris, Thessaloniki). The XI BANTAO congress is being held on 26-29 September 2013 in Timisoara (President--A. Schiller, Timisoara). At the VII BANTAO Congress for the first time a CME Course was organized by ERA/EDTA and ISN/COMGAN entitled "Frontiers in Nephrology" with seven distinguished speakers. Very important event in the existence of BANTAO is the appearance of the BANTAO journal in 2003. The BANTAO journal has been published biannually since 2003. In the past 10 years, 20 regular issues; 2 supplements (Antalia and Chalkidiki congresses) have been published. Editors of the journal were as follows: 2003-2005--D. Nenov, Editor; 2005-2009--A. Basci, Editor; 2009--Goce Spasovski, Editor. Until now 332 papers have been published. The BANTAO journal is on EBSCO, DOAJ, SCOPUS. After the First Congress of BANTAO, F. Valderrábano, chairman of the EDTA--ERA Registry, at that time, wrote in Nephrology Dialysis Transplantation (1996) 11:740: "Nephrologists of the Balkan countries meet across political frontiers and war fronts--an example to politicians! a new European Medical Association overcomes Political obstacles." Despite the difficulties imposed by major events, such as devastating wars and catastrophic earthquakes in many countries of the Balkan Peninsula BANTAO has made considerable progress. The BANTAO Congress was established as the major scientific and institutional forum for Balkan nephrologists, with its own journal, indicating our will to communicate, to collaborate, to get to know each other and to share our difficulties. Now, we expect further successful work of BANTAO.

  7. William Shakespeare and Slovene dramatists (III: (1930-2010

    Full Text Available In the final part of my study I shall present Shakespeare's influence on Slovene dramatists from the 1930s to the present time. In this period an almost unbelievable growth in Slovene cultural activities took place. This is also reflected in a very large number of new Slovene playwrights who have written in this time, in their international orientation in dramatic art as well as in the constantly growing number of permanent (and ad hoc theatre companies. Communication regarding new theatrical tendencies not only in Europe but also in the United States of America and % during the past decades % also in its global dimension has become much easiers than in previous periods and this resulted also in the application of new dramatic visions in playwriting and in theatrical productions in Slovenia. These new movements include new techniques in writing, such as symbolism, futurism, expressionism, constructivism, surrealism, political drama, the theatre of the absurd and postmodernism, which have become apparent both in new literary techniques and in new forms of production. In this period Classical drama still preserved an important role in major Slovene theatres. Plays written by Greek playwrights, as well as plays written by Shakespeare, Molière, Schiller etc. still constitute a very relevant part of the repertoire in Slovene theatres. Besides, Slovene theatres have also performed many plays written by modern playwrights, as for example by Oscar Wilde, L. N. Tolstoy, I. S. Turgenev, Henrik Ibsen, August Strindberg, G. Hauptmann, G. Büchner, G. B. Shaw, A. P. Chekhov, John Galsworthy, Luigi Pirandello, Eugene O'Neill and many other contemporary playwrights. In the period after the Second World War the influence of American dramatists has been constantly growing. This variety also resulted in the fact that direct influence of Shakespeare and his plays upon Slovene dramatists became less frequent and less noticeable than it had been before. Plays

    duality,”namely underlying concepts between “pastity”and “modernity”and his reconciliation of the conflict between rationality and belief.This basic thought appears not only implicitly in Lessing’s ideas but explicitly in the textual practice of his literary creation.Therefore,the third way that Goethe and Schiller tried to open up,the so-called “classical mirror,”in fact,began as early as the Age of Enlightenment.The sign of “Moderate enlightenment ” shows Lessing ’s basic position, and the choice of “human education”program shows his down-to-earth attitude towards academic exploration,which,more importantly,reflects the specific location of the doctrine of the golden mean he chose.

    ., & Benvenuto, O. G. (2001, MNRAS, 323, 471) but in that paper the mass transfer was mimicked by subtracting mass to a progenitor of 1 M⊙ to obtain the mass for the desired object. Actually, our binary code has a full nuclear reactions network for hydrogen and helium burning that allowed us to follow the abundances of fifteen isotopes throughout the entire evolution of the star. We have also included a detailed equation of state. The mass loss treatment is non conservative. We have modified the conditions for the beginning and end of mass transfer episodes. In our previous version, we assumed it to occur when the stellar radius was greater or smaller, respectively, that the Roche Lobe radius for the star. This introduced numerical problems, especially at the end of mass transfer phases. We adopted H. Ritter (1988, A&A, 202, 93) formulation that considers a finite scale height in the stellar atmosphere. The numerical behaviour in much more satisfactory, besides that it constitutes a more appropriate description for the physical problem. We perform the calculations for the evolution of the primary star in a close binary system of initial mass 2 M⊙, initial period of 1 day, initial mass ratio of 1.4142 and solar metallicity. We have done the calculations in four cases: A) with diffusion and all Roche Lobe overflows, B) with diffusion and only the first Roche Lobe overflow, C) without diffusion and all Roche Lobe overflows, D) without diffusion and only the first Roche Lobe overflow. Cases B) and D) where performed to compare with results obtained for Althaus et al. (2001). The main conclusion of this work is that the age of these objects is mainly determined by diffusive effects, and the late stages of mass transfer, not considered in Althaus et al. (2001), constituted a minor effect on the scales of cooling times.

    main characteristics of an IWRM. An analysis of present IWRM practices and strategies in the basins and test sites, as well as an analysis of water administration, related organizations and water laws was conducted in the frame of the project to evaluate the status of water management in the regions and develop approaches to enhance the situation and to transfer professional IWRM expertise. For investigating the actual status of the system and its development in the past a thorough system analysis was conducted as the fundament for further activities. With the knowledge of the historical development of climate conditions, runoff regime, glacier development and similar basin-related information it is possible to extrapolate the system response for future developments. One approach of the system analysis is the delineation of hydrological response units (HRUs). "Hydrological response units are distributed, heterogeneously structured entities having a common climate, land use and underlying pedo-topo-geological associations controlling their hydrological dynamics" (FLÜGEL 1995, Hydrological Processes, Vol.9, 423-436). HRUs can be used as model entities to simulate the hydrology of the basin using a distributive hydrological modeling system. The hydrologic modeling is the next logical step after the HRU delineation. The novel hydrological model JAMS/J2000g, developed at the Friedrich-Schiller-University of Jena, was used for this purpose. For managing data (time series, GIS-data and documents) within the BRAHMATWINN project, a River Basin Information System (RBIS) was developed. In addition, RBIS provides the technical basis of a decision support system. For this challenge, the frontend offers different analysis functions. The structure of the web application RBIS consists of several components. One element is responsible for application administration tasks, e.g. the access management. Another component was constructed as a variable number of application modules plus a

    mean axial and normal particle fluctuations and the particle cross moment are generally measured lower when using PIV. Simulations are performed using FluentR and the model Euler-Euler, where both phases are regarded as being continua. The kinetic theory of granular flow (KTGF) is included for the solids phase. Initially only the single transport pipe is simulated in 2d and 3d. The flow in this pipe is dilute and therefore the simulations which included KTGF and the Gidaspow drag model are compared to simulations enabling the constant viscosity model (CVM) and the Schiller-Naumann drag model. The results from the simulations show very little difference between the two simulations. Euler-Euler with KTGF 2d and 3d simulations are performed for all of the particle types. Little difference between 2d and 3d simulations are observed. A comparison between simulations and experimental results, LDA and PIV, showed good agreement for axial particle velocity for all of the particle types.

    orden del rey taciturno, aún no se sabe exactamente por qué causa, aunque don Gregario Marañón (2 presume, en su biografía de Antonio Pérez, valido de don Felipe, que fue debido a las intrigas palaciegas que llevaron al asesinato de Juan de Escobedo, Secretario en el gobierno de los Países Bajos de don Juan de Austria, el hermano bastardo del rey español, para acallar cualquier infidencia sobre las relaciones entre la princesa y Antonio Pérez. Para otros la amistad era con don Felipe, aunque la austeridad del monarca no da pie para pensar en ello.

    En el vértice de tantas intrigas se halló nuestro galeno escritor y aún fue llamado, afirma él, a prestar sus servicios al infante don Carlos. De su prudencia y discreción nos habla el talento con que esquivó hacerse cargo del ilustre enfermo, en este paso operático (con tema de Schiller y música de Verdi, pues no debía ser un paciente fácil el degenerado príncipe cuya muerte se llegó a pensar fue ordenada por su regio padre para evitar a España un monarca indigno -otros dicen que debido a los celos por las relaciones de aquel con su madrastra, Isabel de Valois-. De todos modos el Infante don Carlos era un caso de difícil tratamiento. Esquizofrénico paranoide, es el diagnóstico histórico que de él hace Vallejo Nájera (3: retardado mental, de cabeza muy grande para su cuerpo. “No me gusta su aspecto, no sé lo que será de él” comentaba su abuelo el Gran Emperador.

  18. Light Dawns on Dark Gamma-ray Bursts

    Science.gov (United States)

    2010-12-01

    Gamma-ray bursts are among the most energetic events in the Universe, but some appear curiously faint in visible light. The biggest study to date of these so-called dark gamma-ray bursts, using the GROND instrument on the 2.2-metre MPG/ESO telescope at La Silla in Chile, has found that these gigantic explosions don't require exotic explanations. Their faintness is now fully explained by a combination of causes, the most important of which is the presence of dust between the Earth and the explosion. Gamma-ray bursts (GRBs), fleeting events that last from less than a second to several minutes, are detected by orbiting observatories that can pick up their high energy radiation. Thirteen years ago, however, astronomers discovered a longer-lasting stream of less energetic radiation coming from these violent outbursts, which can last for weeks or even years after the initial explosion. Astronomers call this the burst's afterglow. While all gamma-ray bursts [1] have afterglows that give off X-rays, only about half of them were found to give off visible light, with the rest remaining mysteriously dark. Some astronomers suspected that these dark afterglows could be examples of a whole new class of gamma-ray bursts, while others thought that they might all be at very great distances. Previous studies had suggested that obscuring dust between the burst and us might also explain why they were so dim. "Studying afterglows is vital to further our understanding of the objects that become gamma-ray bursts and what they tell us about star formation in the early Universe," says the study's lead author Jochen Greiner from the Max-Planck Institute for Extraterrestrial Physics in Garching bei München, Germany. NASA launched the Swift satellite at the end of 2004. From its orbit above the Earth's atmosphere it can detect gamma-ray bursts and immediately relay their positions to other observatories so that the afterglows could be studied. In the new study, astronomers combined Swift

    Headquarters in Garching near Munich (Germany) in mid-November 1995. Here they will experience front-line science and partake in the daily life of one of Europe's foremost scientific establishments. Assisted by professional astronomers, they will prepare and carry out real astronomical observations with the 1.4-metre CAT (Coude Auxiliary Telescope) and the very advanced 3.5-metre NTT (New Technology Telescope) from ESO's remote control centre. They will also begin the treatment of the registered data and, if possible, arrive at tentative interpretations. The week will undoubtedly be very hectic, but it will of course also include events of a more social character which will further emphasize the pan-European nature of this unique visit. ESO will provide more details about this programme in early November 1995, including the planned media coverage.

    gravitational field of the galaxies. The astronomers believe that the two tidal tails result from a dramatic interaction between the quasar host galaxy and one or more of the close companion galaxies. The longer, southern tail extends over more than 150,000 light years, one-and-a-half times the diameter of the Milky Way. In many respects this distant interaction resembles the well known Antenna Galaxies (see the Hubble image ), where two nearby galaxies distort each other in a gravitational dance. Galaxy mergers in the young Universe In the case of HE 1013-2136 , a number of knots can be seen along both tidal tails. In particular, the object just below the quasar image, most easily seen in the sharpened image ( PR Photo 20b/01 ), lies at a projected distance of only 20,000 light years. This is about two-thirds of the distance from the Earth to the center of the Milky Way galaxy. This object is most likely a companion that is interacting with the quasar host. Recent observations of nearby quasars have revealed that they mostly reside in elliptical galaxies . Numerical simulations suggest that such galaxies can be formed by successive mergers of spiral galaxies. Klaus Jäger and his colleagues point out that " with the VLT observations of HE 1013-2136 , we may be directly witnessing such a dramatic merger of galaxies. The special significance of this observation is the great distance and hence the comparably early time at which this happens, when the Universe was about one third as old as it is now ". He adds: " This particular galaxy will most probably evolve into the same type of elliptical quasar host galaxy that we observe much nearer to us, that is, at much later times ".

    velocities of the interacting matter. The astronomer team therefore intends to carry out further adaptive-optics imaging and spectroscopy with the ESO instruments later this year. Great prospects for related research projects The detection of this new object shows that direct proofs for the existence of circumstellar disks in distant star-forming regions are possible with currently available telescopes. It also represents an important step forward for the preparation of scientific programmes devoted to the formation of stars and planets that will soon be carried out with the ESO Very Large Telescope (VLT). The new results demonstrate that the high-resolution images that will be obtained with the future giant telescopes and, especially, with the VLT Interferometer (VLTI) will most likely lead to important breakthroughs in our understanding on the complicated processes of star formation. This will in turn cast new light on how the Sun and the Earth came into existence, more than 4.5 billion years ago.

    als Transformation und Produktion kultureller Erfahrungen interpretiert, auch um aus den Engführungen der im deutschsprachigen Raum noch dominierenden Mediennutzungs- und Medienwirkungsforschung herauszugelangen. Für die pädagogische Auseinandersetzung wird daraus abgeleitet, dass nicht die didaktische Nützlichkeit, sondern die bildungstheoretische Bedeutung von Computerspielen zu fokussieren sei. Den bisher vorherrschenden teleologischen Lernkonzepten wird hier ein genealogischer Ansatz gegenübergestellt, bei dem die Erfahrungen und Lernprozesse im Zuge der Spielhandlungen selbst thematisiert werden. An einem Beispiel wird abschliessend verdeutlicht, wie das theoretisch-methodische Vorgehen einer hierauf ausgerichteten Analyse ausgestaltet und wie bei einer solchen Analyse die medial-kulturelle Praktik des Computerspielens pädagogisch rekonstruiert werden kann. Steffen Malo, Maik Neudorf und Thorben Wist ordnen ihren Beitrag in den Kontext des Game-based Training (GBT ein und berichten über das Projekt Alphabit, bei dem es darum geht, computerbasierte Lern- bzw. Trainingsspiele als ergänzendes methodisches Mittel für Alphabetisierungs- bzw. Grundbildungsprogramme einzusetzen. Vorgestellt werden die im Projekt entwickelten konzeptionellen Überlegungen zu den Rahmenbedingungen, zur Auswahl der Inhalte, zu unterstützenden instruktionalen Hilfen, zu den Entwicklungsprozessen und zu methodischen Aspekten des spielerischen Lernens in virtuellen Umgebungen. Ausserdem werden erste Ansätze für die Umsetzung präsentiert und offene Forschungsfragen aufgezeigt. Auch Jochen Pfannstiel, Volker Sänger und Claudia Schmitz berichten über ein Projekt, das für die Bildungspraxis konzipiert wurde und auch bereits erprobt wird. Hier geht es um Game- based Learning im Hochschulbereich, genauer: um ein Lernspiel, das ergänzend zu einer Pflichtvorlesung in der Informatik eingesetzt wird, um Studierende dazu zu motivieren, sich während des Studiums intensiver und

    and experimentalists were taking part in the development of the concept of so-called polaritons in semiconductors, i.e. mixed states, when the 'mechanical' particle exciton mixes with the light wave. Pekar and Rashba of Kiev, Ginzburg and Agranovich of Moscow, Kaplyansky, Razbirin and Uraltsev of Leningrad, and also the above-mentioned American researchers, made the greatest contribution to the development of this sophisticated problem. Recalling the exciton physics of crystals of the 1950s and 1960s, I should call that time, after Schiller and Goethe, a period of Sturm und Drang. But even later on, the stormy waves of exciton spectroscopy did not calm down. There appeared lasers, which permitted Yaroslav Pokrovsky of the Institute of Electronics in Moscow to observe the hyperfine structure of exciton impurity complexes. The intense sources of light were also used for observation of the electron--hole condensate in semiconductors. But the initial idea of these investigations was stimulated by the existence of excitons: Bose particles and the attempt to observe their condensation. Veniamin Keldysh, Alexander Rogachev and a number of other Russian and foreign physicists contributed greatly to the solution of that problem. My friend, Carson Jeffries of Berkeley, a physicist and a painter, observed a gigantic (about a millimeter in size) electron--hole droplet in a crystal of germanium, and the results of his experiments were even mentioned in the New York Times. The 'exciton wave' rolled around the world, but its birthplace was Gross' small laboratory at the Physico-Technical Institute. It is most vexatious to read in a great many foreign textbooks on solid state physics that the Strasbourg professor S Nikitin was first to observe the exciton in cuprous oxide. That is not true at all! Nikitin bears no relation whatever to the discovery of the exciton. Gross first discovered a hydrogen-like series in a semiconductor in 1951 and published his findings in the Russian
