Efficient sorting of waste by means of dry stabilisation and separation of inert materials; Effiziente Sortierung von Restabfall durch Trockenstabilisierung und Inertstoffabscheidung

Heering, B.M. [Herhof-Umwelt GmbH, Solms-Niederbiel (Germany); Heil, J. [Lehr- und Forschungsgebiet Kokereiwesen, Brikettierung und Thermische Abfallbehandlung, Aachen (Germany)

1999-07-01

Sorting of waste takes place in two stages: First, the waste is dried to a moisture of 15 % by weight, making use of its microbial activities. After this, the stabilised residue is sorted according to grain size, density, magnetic susceiptibility, electric conductivity, and comminution characteristics. This way, recyclable materials are recovered almost completely (e.g. metals, stone, ceramics, glass). The refuse-derived fuel fraction has significantly lower heavy metal concentrations because the metals were sorted out, and its calorific value and homogemeity are optimised as well. The fuel fraction can be combusted at once or stored for further use. [German] Die stoffliche Trennung des Restabfalls kann in zwei aufeinander folgende Schritte unterteilt werden. Den ersten Schritt stellt eine Trocknung unter Ausnutzung der mikrobiellen Aktivitaeten des Materials dar. Durch diese Massnahme wird ein trockenes Material mit einer Restfeuchte von unter 15 Gew.-% erzeugt. Den zweiten Verfahrensschritt stellt die Sortierung des stabilisierten Restabfall dar. Als Sortierkriterium werden die Eigenschaften Korngroesse, Dichte, magnetische Suszeptibilitaet, elektrische Leitfaehigkeit und Zerkleinerungsverhalten angewandt. Hierdruch ist eine nahezu vollstaendige und sortenreine Rueckgewinnung der im Abfall enthaltenen Wertstoffe wie Eisen-/Nichteisenmetalle, Steine/Keramik und Glas sichergestellt. Weiterhin erhaelt man als Brennstofffraktion das Trockenstabilat {sup circledR}. Aufgrund der Abtrennung der hauptsaechlichen Schwermetalltraeger, Eisen- und Nichteisenmetalle, besitzt dieser Sekundaerbrennstoff gegenueber dem unbehandeltem Restabfall deutlich verminderte Schwermetallkonzentrationen. Zudem sind seine verbrennungstechnisch relevanten Eigenschaften Heizwert und Homogenitaet deutlich optimiert. Das Trockenstabilat {sup circledR} wird sofort oder zeitversetzt der energetischen Verwertung zugefuehrt. (orig.)

Ein kombinierter Operationsansatz zur Therapie der rektovaginalen Endometriose auf der Basis histologischer Befunde

Directory of Open Access Journals (Sweden)

Köhler C

2008-01-01

Full Text Available Einleitung: Eine Endometriose des Septum rectovaginale kann oberflächlich dem Darm aufliegen oder die Darmwand infiltrieren. Durch bildgebende Verfahren kann jedoch präoperativ eine Infiltration des Darms weder hinreichend bestätigt noch ausgeschlossen werden, was zu einem therapeutischen Dilemma führt, da nur die Darmwand eindeutig infiltrierende Endometrioseprozesse durch eine Darmresektion behandelt werden sollten. Wir möchten ein neues Operationsverfahren vorstellen, das eine intraoperative Differenzierung zwischen einer oberflächlichen und einer infiltrativen Darmendometriose erlaubt. Patienten und Methodik: 70 Patientinnen mit rektovaginaler Endometriose wurden nach einem neu entwickelten kombinierten vaginal-laparoskopisch-abdominalen Verfahren operiert. Diese Operationsmethode wird Schritt für Schritt vorgestellt. Die Entscheidung zur Darmresektion wurde dabei allein aufgrund der intraoperativen Befunde und nicht aufgrund der präoperativen bildgebenden Diagnostik getroffen. Alle Resektate wurden standardisiert histologisch aufgearbeitet. Ergebnisse: Ob eine Darmresektion notwendig war, ließ sich intraoperativ anhand der Präparation des rektovaginalen Septums entscheiden. Daher wurden nur bei Patientinnen mit gesichertem infiltrativem Darmbefall Darmresektionen unter Erhalt des Mesointestinums durchgeführt. Weder intraoperative noch postoperative Komplikationen wie Anastomoseninsuffizienzen oder Restharnmengen traten auf. Diskussion: Die vorgestellte Operationsmethode zur Therapie der rektovaginalen Endometriose erlaubt eine exakte Diagnosestellung und präzise Therapieentscheidung bei minimaler Morbidität. Die Resektion des Darmschlauches ohne Mesoresektion ist ausreichend, da sich die Endometrioseknoten – wie histologisch bewiesen wurde – nur im ventralen Darmbereich befinden. Durch die Mesoerhaltung werden die vegetativen Funktionen des kleinen Beckens nicht beeinträchtigt.

The second print run of 'ground water chemistry' is supposed to be a practice oriented guideline for a fast introduction into the thermodynamic modeling. Besides a minimum theoretical background the book is focused to practical examples using the computer program PHREEQC. The reprint includes the additional possibilities of the CD-MUSIC concept for surface modeling. Examples concerning reactive mass transport include not only the 1D transport code PGREEQC, but also a 3D example using PHAST und the graphical user interface WPHAST. Uncertainties of thermodynamic data may be modeled using the program LJGUNSKILE. As before detailed descriptions allow the user to reach step by step more complex hydrogeochemical modeling. All of the cited computer codes are compiled on an enclosed CD. [German] Auch die zweite Auflage von 'Grundwasserchemie' bietet als praxisorientierter Leitfaden einen schnellen Einstieg in die thermodynamische Modellierung.

Von Roll RCP method - first experiences; Von Roll RCP - Verfahren. Erste Erfahrungen

Capitaine, P.; Engweiler, J. [Roll Umwelttechnik AG, Zuerich (Switzerland)

The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen. The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of (heavy) metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. [Deutsch] Das reststoffoptimierte RCP Verfahren ist als Alternative zur thermisch optimierten Rostverbrennung von Restabfaellen konzipiert. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt. In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen. Optional wird diese Schmelzschlacke in einem dritten Schritt derart von (Schwer-) Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann. Die Nutzung der zirkulierenden Wirbelschicht - Nachbrennkammer zur Abgasbehandlung vereinfacht die weitergehende Abgasbehandlung. Trotz verringertem Rauchgasvolumen und damit hoeheren Schadstoffkonzentrationen im Rohgas werden die Gesamtemissionen gegenueber konventionellen Anlagen verringert. (orig./SR)

A case of Graves` disease occurring in a patient with hemiagenesis is presented. The detection of the rare occurrence of a congential hemiagenesis is often made by either clinical symptoms of thyroid dysfunction or anatomical abnormalities such as nodular goiter. The symptoms of hyperthyroidism in the current case led to the diagnostic confirmation by scintiscanning and ultrasonography of an absent lobe. Anti-thyroid antibody studies documented the presence of Graves` disease within the remaining lobe. (orig.) [Deutsch] Die Hemiagenesie der Schilddruese stellt eine seltene angeborene Veraenderung dar. Diese angeborene Variante der Schilddruesenanlage wird in den meisten Faellen durh Auffaelligkeiten der Funktion oder der Groesse des vorhandenen Schilddruesenlappens zufaellig gefunden. Der Fall einer 57jaehrigen Frau mit einer Schilddruesenhemiagenesie in Kombination mit einer Immunthyreopatie Basedow wird vorgestellt. Die Zuweisung der Patientin zur Untersuchung erfolgte wegen einer Schilddruesenueberfunktion. Die erforderlichen diagnostischen Schritte zur Erstellung dieser beiden Schilddruesenveraenderungen waren ein 99m-Tc-Schilddruesenszintigramm, Ultraschall und Laborparameter der Schilddruese (fT4, TT3, bTSH, TAK, TPO, TRAK).

Emissions trading listed as a flexible mechanism under the Kyoto Protocol is regarded as a market economy way in climate protection. Since 2005 the European Emissions Trading System (EU ETS) is the central climate policy instrument for reducing the emissions of greenhouse gases, in particular for carbon dioxide (CO{sub 2}). For years, however, the CO{sub 2} price is too low to direct the politically and socially targeted technical innovations in the electricity sector and the industry. The article analyses the temporary and structural causes of this problem, highlights the EU's reform efforts and points to areas of activity, the basis of which the EU ETS may act in the future as a central instrument for climate protection in the European Union. [German] Der im Kyoto-Protokoll als flexibler Mechanismus aufgefuehrte Emissionshandel gilt als marktwirtschaftlicher Weg in den Klimaschutz. Das Europaeische Emissionshandelssystem (EU ETS) ist seit 2005 das zentrale klimapolitische Instrument zur Senkung des Ausstosses von Treibhausgasen, insbesondere fuer Kohlenstoffdioxid (CO{sub 2}). Seit Jahren ist der CO{sub 2}-Preis jedoch zu gering, um die politisch und gesellschaftlich angestrebten technischen Innovationen im Stromsektor und der Industrie zu lenken. Der Artikel untersucht die temporaeren und strukturellen Ursachen dieses Problems, beleuchtet die Reformbestrebungen der EU und zeigt Handlungsfelder auf, anhand derer das EU ETS auch in Zukunft als zentrales Instrument fuer Klimaschutz in der Europaeischen Union fungieren kann.

Breast cancer is the most common cancer and the leading cause of cancer deaths in women worldwide. Mammography is the only imaging technique approved for nationwide breast cancer screening. Digital full field mammography has improved mammographic image quality. Nevertheless, mammography has a low positive predictive value and a low sensitivity especially in mammographically dense breasts. One of the major limitations is the inherently low contrast between healthy breast parenchyma and breast cancer. Phase contrast imaging is based on the phase shift that occurs when X-rays encounter a change in refractive index between different materials. The improved soft tissue contrast makes the technology particularly promising for breast diagnostics. The studies presented here suggest that phase contrast imaging provides additional diagnostic information both using phase contrast mammography and phase contrast computed tomography (CT). This paper provides an overview of the basic principles of the phase contrast imaging and describes recent developments towards in vivo and ex vivo phase contrast imaging of the breast. (orig.) [German] Brustkrebs ist weltweit die haeufigste Tumorerkrankung und die haeufigste Krebstodesursache der Frau. Die Mammographie ist die einzige zugelassene bildgebende Methode zur Brustkrebsfrueherkennung im Rahmen flaechendeckender Screeningprogramme. Trotz Verbesserung der Bildqualitaet und der Befundungsperformance durch die Einfuehrung der digitalen Vollfeldmammographie sind der positiv-praediktive Wert und die Sensitivitaet der Mammographie insbesondere bei mammographisch dichtem Druesenkoerper eingeschraenkt. Dies ist u. a. auf die geringen Dichteunterschiede zwischen gesundem Brustdruesengewebe und intramammaeren Malignomen zurueckzufuehren. Die Phasenkontrastbildgebung macht sich die Phasenverschiebung von Roentgenstrahlen zunutze, die an Materialgrenzen mit unterschiedlichen Brechungsindizes entsteht. Die Technik bietet einen potenziell verbesserten Weichgewebekontrast fuer Gewebe mit geringen Absorptionsunterschieden wie die weibliche Brust. Die vorgestellten Studien deuten fuer verschiedene Techniken der Phasenkontrastbildgebung einen Zugewinn an diagnostischen Informationen sowohl im Rahmen der Phasenkontrastmammographie als auch der Phasenkontrast-CT an. Die vorliegende Arbeit gibt einen Ueberblick ueber die technischen Grundlagen der Phasenkontrastbildgebung und fasst die aktuelle Studienlage zur Ex-vivo- und In-vivo-Phasenkontrastbildgebung der weiblichen Brust zusammen.

Mechanical-biological waste treatment implies biological drying and mechanical separation; it produces a pollutant-free fuel fraction with good calorific value and inorganic fractions available for recycling. Apart from some prototypes, mostly static aerobic reactors are used. For moist residues, dynamic reactors may be interesting as they permit coupling of thermal and mechanical processes, i.e. parallel biological drying and mechanical separation. A discontinuous rotary kiln reactor for biological drying of residues was developed in this project. (orig.) [German] Die mechanisch-biologische Aufbereitung von Restabfaellen (MBA) hat sich zu einem Systembaustein innerhalb der Restabfallentsorgung entwickelt. Das Hauptanwendungsziel besteht darin, durch die Kombination von biologischer Trocknung mit mechanischen Stofftrennverfahren eine heizwertreiche und schadstoffentfrachtete Fraktion mit Brennstoffeigenschaften, sowie verwertbare anorganische Fraktionen aus dem Restabfall zu gewinnen. Die Ausgangssituation zeigte, dass, abgesehen von einigen prototypischen Anlagen, in der MBA-Technologie hauptsaechlich statische, aerob arbeitende Reaktoren (Rottetunnel und Rotteboxen) fuer den biologischen Schritt eingesetzt werden. Fuer feuchte Restabfaelle erscheint es interessant, dynamische Reaktoren einzusetzen, die die Kopplung thermischer und mechanischer Prozesse erlauben, die also die biologische Trocknung und den mechanischen Aufschluss parallel zulassen. Im Rahmen des Projektes wurde die Steuerung eines diskontinuierlich betriebenen Drehrohrreaktors zur biologischen Trocknung von Restabfaellen entwickelt. (orig.)

Functional magnetic resonance imaging (fMRI) is currently the primary method for non-invasive functional localization in the brain. With the emergence of MR systems with field strengths of 4 Tesla and above, neuronal activation may be studied with unprecedented accuracy. In this article we present different approaches to use the improved sensitivity and specificity for expanding current fMRT resolution limits in space and time based on several 7 Tesla studies. In addition to the challenges that arise with ultra-high magnetic fields possible solutions will be discussed. (orig.)

In diesem Artikel zeigen wir anhand mehrerer Studien bei 7 T, in wieweit die Zugewinne an Sensitivitaet und Spezifitaet verwendet werden koennen, um die bisherigen Grenzen der fMRT-Aufloesung in raeumlicher und zeitlicher Hinsicht auszuweiten. Die neuen Herausforderungen, die mit dem Schritt zu ultrahohen Magnetfeldern einhergehen, werden dabei ebenso diskutiert wie moegliche Ansaetze zu deren Loesung. (orig.)

Als hybride Mischung zwischen Theorieprogramm, politischer Bewegung und praxis- und anwendungsorientiertem Policy-Manual, das zuweilen Züge eines populären philosophischen Lebensratgebers trägt, hat Libertärer Paternalismus viel Zuspruch, aber auch heftige Kritik auf sich gezogen, die in diesem Aufsatz auf ihre Plausibilität geprüft werden. Zu diesem Zweck geben die Autoren zunächst einen kurzen Überblick über Ausgangspunkte, Leitorientierungen und Problemvorgaben des Theorie- und Politikprogramms des Libertären Paternalismus. In einem zweiten Schritt werden zentrale (metaphorische Konzepte und Unterscheidungen des libertär paternalistischen Rationales vorgestellt und problematisiert. Daran anschließend werden drei der prominentesten Kritikpunkte an Libertärem Paternalismus auf den Prüfstand gestellt. Hierzu gehören der Manipulationseinwand, Kritiken, die sich auf grundlegende Rechtfertigungsprobleme des Libertären Paternalismus beziehen, und Einwände, die auf langfristige negative Folgen des Nudging verweisen („Slippery-Slope-Argumente“.

A method of automatic optimisation of screw rotors was investigated with the intention of obtaining a generally applicable method also for other types of energy conversion systems. As in turbomachinery engineering, compressors and engines are developing into separate fields. For example, while the filling process is a secondary consideration in compressors, it is a key element in screw-type engines. Some of the contribution discuss the new field of power supply in automotive fuel cells. [German] Das vorgelegte Heft 9 der Zeitschrift Schraubenmaschinen setzt mit neuen und fortgeschriebenen Beitraegen die 1993 begonnene Schriftenreihe mit dem Themenschwerpunkt Theorie fort. Erstmalig wird der Versuch unternommen, mit Hilfe unterschiedlicher Optimierungsverfahren in Zusammenarbeit mit der Informatik eine Methode zu entwickeln, mit deren Hilfe im ersten Schritt Schraubenrotoren automatisch optimiert werden koennen. Ziel ist es, dieses Verfahren auch auf andere Energiewandler anzuwenden. Wie im Turbomaschinenbau gehen Kompressoren und Motoren zunehmend getrennte Wege. Waehrend zum Beispiel der Fuellvorgang in Kompressoren eher eine untergeordnete Rolle spielt, wird er beim Schraubenmotor zu einem signifikanten Problem fuer die Gestaltung und Energiewandlung der gesamten Expansion. Kenngroessen beschreiben das vorhandene Optimierungspotential. Zu den neuen Anwendungen gehoert der zukuenftige Einsatz der Schraubenmaschine (Kompressor und Expander) fuer die Energieversorgung in automotiven Brennstoffzellen. Erste Ueberlegungen fuehren in dieses Thema vergleichend ein. (orig.)

Im Gespräch: Postkoloniale Theorie und Intersektionalität

Stefan Wallaschek

2015-12-01

Full Text Available Postkoloniale Theorie und Intersektionalität gehören zu den wichtigsten Ansätzen der gegenwärtigen kritischen Sozialwissenschaften. Überraschenderweise scheint es kaum einen Dialog zwischen beiden Ansätzen zu geben. Ich versuche beide Ansätze in den Dialog zu bringen und analysiere sie vor dem Hintergrund der deutschsprachigen akademischen Debatte auf ihre Gemeinsamkeiten und Unterschiede. Zuerst gehe ich dabei auf die Arbeiten von Chandra Mohanty und Kimberlé Crenshaw ein. Während Erstere diskursanalytisch Arbeiten zu ‚Dritte-Welt-Frauen‘ untersucht und einen feministisch-postkolonialen Ansatz entwickelt, richtet Crenshaw ihren Blick auf die Verbindung von Geschlechter- und ‚race‘-Diskriminierung anhand von Gerichtsurteilen in den USA. Ich argumentiere, dass eine konstruktivistische Methodologie auf vier Knotenpunkten beruht und diese den Boden für den Dialog bereiten. In einem zweiten Schritt nutze ich diese für die intersektionale und postkoloniale Analyse der Arbeiten von Sojourner Truth und Clara Zetkin. Truth problematisiert eine gleichrangige Unterdrückung durch Geschlechter- und ‚race‘-Fragen, während Zetkin die hierarchische Unterdrückung durch die spezifische Klassenposition von Frauen hervorhebt. Eine Verbindung beider Ansätze wird im Fazit befürwortet, um Diskriminierungen und Ungerechtigkeiten in Zeiten neoliberaler kapitalistischer Hegemonie multidimensional zu erfassen.

Nach einem Überblick über die Geschichte der Eleganz des Gentleman werden detailliert die einzelnen Schritte des Maßnehmens, Entwerfens, Fertigens erläutert. Dabei wird klar, dass ein Anzug immer eine komplizierte Umgestaltung des männlichen Körpers zu einem von antiker Kunst inspirierten abstrakten Ideal von Nacktheit darstellt. Zu kurz kommt leider jegliche kritische Auseinandersetzung mit der Theorie der Mode, so dass das Resultat zwar sehr anschaulich, jedoch in systematischer Hinsicht für die Modeforschung wenig erhellend ist.Ruth Sprenger clearly depicts the history and practice of a masterly handicraft for interested laypeople and includes many illustrations. Following a survey of the history of the elegance of the gentleman, she elucidates and details the single steps of measurement, design, and completion. It becomes clear that a suit always represents a complicated reconfiguration of the male body to an abstract ideal of nudity inspired by antique art. Unfortunately any critical debate on the theory of art falls short so that the results are admittedly very demonstrative, however in systematical terms they are not all too insightful for fashion research.

Ästhetische Einsamkeit: Bildung außerhalb des Kanons

Full Text Available Es stellt sich die Frage, wie man vom Leben in die Kunst kommt, um sich zu bilden und anschließend, wie man nach der ästhetischen Bildungsphase wieder in das Leben gelangt ohne von den dortigen Anforderungen wieder so sehr vereinnahmt zu werden, dass die Bildung in der realen Welt nicht zur Wirkung gelangt. Weil diese Übergänge schwierig und einsam sind, reduziert sich die Bildungsidee oft auf Pathos: Da man nicht weiß, wie sie funktionieren soll, aber als Idee immer noch für so gut befunden wird, kompensiert man ihre ausbleibende Umsetzung gern mit überschwänglicher Rhetorik.In meinem Beitrag möchte ich aufzeigen, was Bildung jenseits dieser pathetischen Falle, aber auch jenseits der schwierigen und daher oft ausbleibenden Übergänge sein könnte. Dafür werden wir nicht nur die ‚Klassiker‘ der Bildungsidee (Kant und Schiller vorstellen, sondern in einem zweiten Schritt auch Anregungen und Kritik außerhalb dieses Kanons miteinbeziehen (Bergson, Bourdieu und Rancière.

Full Text Available Die Osteoporose und die damit assoziierten Frakturen stellen ein globales Gesundheitsproblem dar. Trotz zahlreicher präventiver Möglichkeiten, die uns heute zur Verfügung stehen, sind weiterhin große Defizite in der Diagnostik und Therapie der Osteoporose vorhanden. Die meisten Patienten werden nach einer Fragilitätsfraktur nicht weiter osteologisch abgeklärt. Im Oktober 2009 begann in der Steiermark die Implementierung des „Fracture-Liaison“- Dienstes (FLD an 4 unfallchirurgischen Abteilungen. Ziel dieses Projekts ist es, möglichst alle Patienten ab dem 50. Lebensjahr, welche aufgrund einer „Low-trauma“-Fraktur stationär behandelt werden, zu erfassen, weitere diagnostische und therapeutische Schritte einzuleiten und somit auch das Risiko für Folgefrakturen zu reduzieren. In den ersten 6 Monaten wurden 404 Patienten erfasst. Nur 15 % hatten zum Zeitpunkt der Fraktur eine osteoprotektive Therapie, obwohl 52 % bereits zumindest eine prävalente osteoporotische Fraktur aufwiesen. Lediglich 59 Patienten (15 % hatten einen normalen 25- Hydroxyvitamin-D-Serumspiegel von 30 ng/mL, wobei 37 Patienten (62 % davon vorsubstituiert waren. Diese ersten Auswertungen zeigen die eklatante Unterversorgung in diesem Patientenkollektiv, welche in Kombination mit der pandemisch vorliegenden Vitamin-D-Defizienz die hohe Dringlichkeit eines interdisziplinären Managements über die chirurgische Versorgung hinaus unterstreicht.

Gas flows in screw-type machines are effecting the energy conversion of the machine by the leakage mass flows and entropy flows inside the machine. The profile meshing clearance and the housing gap have an essential influence. Here the gas flow at the housing gap with non moving gap bounds is investigated. The used and developed measuring and image analysis technique is explained. Qualitative Schlieren pictures of the flow at three different tooth tips, i.e. gap styles are following to enable a comparison of the flow shapes. The application of a plane screw type machine model with moving gap bounds will be meant to be a contribution towards the investigation of the gas flow conditions in the gaps. (orig.) [Deutsch] Gasspaltstroemungen in Schraubenmaschinen wirken als Leckmassen- und Entropiestroeme erheblich auf die Energiewandlungsguete der Maschine. Besonderen Einfluss haben der Profileingriffs- sowie der Gehaeusespalt. In diesem Beitrag wird die Gehaeusespaltstroemung am Nebenrotor mit feststehender Stroemungsberandung untersucht. Nach Erlaeuterungen zur verwendeten und entwickelten Mess- und Bildverarbeitungstechnik folgen qualitative Schlierenbilder der Stroemung an drei unterschiedlichen Zahnkopf- und damit Spaltformen, die einen Vergleich der Stroemungsformen ermoeglichen. Der naechste Schritt zur Klaerung der Stroemungsverhaeltnisse in den Spalten besteht aus der Einfuehrung eines ebenen Schraubenmaschinenmodells mit drehenden Rotorscheiben. (orig.)

Diskussion zu verstehen und soll auf Basis des aktuellen Stands der Forschung potentielle Ansatzpunkte für eine Optimierung des Arztberufes aus familienfreundlicher Perspektive darstellen und insbesondere zur weiteren Diskussion anregen.Ergebnisse: Einige grundlegende Schritte zur Vereinbarkeit von Beruf und Familie wurden bereits getan, beispielsweise die Bereitstellung von Betreuungsplätzen oder das zunehmende Angebot einer flexibleren Arbeitszeitgestaltung. Dennoch scheinen diese Maßnahmen, da weder flächendeckend umgesetzt noch ausreichend, nicht zu genügen, um eine Bindung von Nachwuchskräften zu sichern. Gerade Frauen in Führungspositionen sind weiterhin selten zu finden.Schlussfolgerung: Ärztinnen und Ärzte wünschen sich mehr Lebensqualität durch die Vereinbarkeit von Beruf und Familie. Der Ausbau familienfreundlicher Angebote ist als notwendiger Schritt zu sehen, um eine zufriedenstellende Positionierung von Medizinerinnen in den Bereichen Beruf und Familie zu ermöglichen .Um jedoch präzise sagen zu können, welche Maßnahmen ergriffen werden müssen, bedarf es einer genauen Datenbasis bspw. in Form von detaillierten Mitarbeiterbefragungen.

Four-dimensional data assimilation as a method for coupling two meteorological model systems of different scales; Vierdimensionale Datenassimilation als Methode zur Kopplung zweier verschiedenskaliger meteorologischer Modellsysteme

A method of coupling two meteorological models of different scales must meet certain requirements: First, even a big difference in resolution between the two models must not produce disturbances in the smaller-scale model. This means that most nesting approaches are unfit for the purpose. The method presented here is not limited to meteorological models. It can be enhanced without much difficulty to dispersion models taking account of chemical atmospheric reactions, as e.g. in the CTM of the EURAD model or in DRAIS as an enhancement of the KAMM version. [German] Das Ziel dieser Arbeit bestand in der Entwicklung eines geeigneten Kopplungsverfahrens zweier verschiedenskaliger meteorologischer Modelle, das in einem Ein-Weg-Nesting dem kleinerskaligen Modell ermoeglicht, sowohl instationaere superskalige Verhaeltnisse als auch modellinterne kleinraeumige Prozesse miteinander zu verbinden. Im Rahmen des Projektes TFS mussten hierbei entscheidende Bedingungen an das Kopplungsverfahren gestellt werden. Allen voran darf vor allem ein auch grosser Unterschied in der Aufloesung der beiden verschiedenskaligen Modelle keine kuenstlichen Stoerungen im kleinerskaligen Modell produzieren. Somit scheiden die sonst ueblichen Nestingansaetze fuer diesen Fall aus. Das Verfahren ist derart konzipiert, dass es sich nicht auf rein meteorologische Modelle beschraenkt. Eine Ausweitung auf Ausbreitungsmodelle unter Beruecksichtigung chemischer Reaktionen in der Atmosphaere, wie sie etwa im CTM des EURAD-Modells oder im DRAIS als Erweiterung der KAMM-Version zur Verfuegung stehen, stellt keinen allzu grossen Schritt mehr dar.

Cost-reducing programmes are only the first step in a series of measures to be taken by the power utilities in order to become fit for the free competition markets. A great number of empirical studies on the future power markets do show that for the customers, prices are a priority criterium, but offering competitive prices alone will not suffice to keep one`s competitive edge. The negative consequences of pure price competition (shown by the aviation industry) and the lessons to be learned from ``intelligent`` branches of industry, (eg. mineral oil and cigarettes), who have been clever enough to avoid price cutting wars, demonstrate that there are chances for development also in deregulated power markets. (orig./CB) [Deutsch] Zur Vorbereitung auf die anstehende Liberalisierung muss eine Neuausrichtung der EVU schnellstmoeglich erfolgen. Reine Kostensenkungsprogramme sind dabei nur der erste Schritt, um fuer den Wettbewerb fit zu werden. Hierzu zaehlt die strategische und marketingorientierte Ausrichtung des Unternehmens auf den Wettbewerb. Zahlreiche empirische Studien zum EVU-Markt kommen zwar zu dem Ergebnis, dass aus der Sicht des Kunden der Preis einen hohen Stellenwert einnimmt. Ein wettbewerbsorientierter Preis ist notwendig, reicht aber zum erfolgreichen Ueberleben im Wettbewerb alleine nur bei ueberlegener Kostenfuehrerschaft aus. Die negativen Auswirkungen eines reinen Preiswettbewerbs (Luftfahrt) sowie die Lehren aus `intelligenten` Branchen (Mineraloel-, Zigarettenindustrie), die dies vermeiden, zeigen die vielfaeltigen Entwicklungsmoeglichkeiten auch fuer den Energie-Wettbewerbsmarkt auf.

But this growth in knowledge does not significantly promote the demand for a reformulation of “general” (historiography-history, which can already be considered traditional in terms of gender history. A first step in this direction might be possible through the formulation of a theory of difference, which can become an analytical framework for a pluralistic “new” narrative.

The first step in diagnosing spinal lesions is to define the anatomical location, especially via magnetic resonance tomography, which is also helpful for histopathologists. However, definite diagnosis is based on histologic and cytologic examinations especially in the case of fine-needle biopsies. In this short review the principal histopathologic diagnoses of primary and secondary tumors and tumor-like lesions of the spine itself, the epidural space, the spinal meninges and nerve roots, and the spinal cord are addressed. The significance of immunohistochemistry for differential diagnosis or, in cases of spinal metastasis, for determination of the primary is discussed. (orig.) Die anatomische Zuordnung einer raumfordernden spinalen Laesion, v. a. mit Hilfe der Magnetresonanztomographie in hervorragender Weise moeglich, ist ein erster Schritt der diagnostischen Eroerterung und auch fuer den Histopathologen diagnostisch hilfreich. Die definitive Diagnose ist letztlich nur an histologischen Schnittpraeparaten von Biopsien oder zytologisch moeglich, letzteres v. a. an Feinnadelpunktaten insbesondere im Falle von Karzinomzellen. In dieser kurzen Uebersicht werden die prinzipiell moeglichen pathologischen Diagnosen eroertert, die bei primaeren und sekundaeren Tumoren und tumorartigen nichtneoplastischen Laesionen der Wirbelsaeule selbst, des spinalen Epiduralraums, der Meningen und Wurzeln sowie des Rueckenmarks vorkommen. Die Bedeutung immunhistochemischer Untersuchungen wird diskutiert, insbesondere hinsichtlich der differenzialdiagnostischen Abgrenzung maligner Tumoren und - im Falle von Metastasen - mit Blick auf deren Herkunft bzw. den Sitz des Primaertumors.

The reorientation of energy policy is a key issue. The Council of Environmental Experts considers the further use of atomic energy to be irresponsible and recommends a new orientation. Recommendations are made on ecology-centered taxation. Critical comments are made in the context of conservation of nature, where many species of plants and animals still continue to be endangered. The conservation programme of the Federal government, which also comprises a system of large, interconnected biotopes on 10% of Germany's total surface, is approved, and the potential contribution of sustainable agricultural and forestry policy is discussed in a separate chapter. Further subjects discussed are recycling and waste management, protection of water and soil, air pollution abatement, health protection and genetic engineering. The environmental aspects of Eastern European states becoming EC members are gone into in particular. The network of Europen Environmental Councils, for which the German Council of Environmental Experts currently acts as a coordinator, makes intensive efforts to improve environmental counselling in these states. [German] Eines der Schwerpunktthemen des Umweltgutachtens ist die Neuordnung der Energiepolitik. Der Umweltrat haelt die weitere Nutzung der Atomenergie vor allem wegen der Risiken der Entsorgung nicht fuer verantwortbar. Er befuerwortet die Einleitung einer Energiewende. Zur oekologischen Steuerreform werden weiterfuehrende Empfehlungen unterbreitet. An vielen Stellen nimmt der Rat die Umweltpolitik auch kritisch unter die Lupe. Er weist auf den hohen Handlungsbedarf im Naturschutz hin. Eine dauerhafte Trendwende beim Grad der Gefaehrdung heimischer Tier- und Pflanzenarten sei in Deutschland noch nicht erreicht. Der Rat bestaetigt in diesem Zusammenhang die naturschutzpolitische Konzeption der Bundesregierung fuer einen Naturschutz auf der ganzen Flaeche, kombiniert mit einem grossflaechigen Biotopverbundsystem auf 10% der Landesflaeche. Der Beitrag, den eine nachhaltige Wald- und Forstwirtschaft hierzu leisten kann, wird in einem Sonderkapitel dargestellt. Weitere Themen des Gutachtens sind Kreislauf- und Abfallwirtschaft, Gewaesser- und Bodenschutz, Klimaschutz und Luftreinhaltung sowie der Schutz der menschlichen Gesundheit und Fragen der Gentechnik. In besonderer Weise widmen sich die Gutachter den Umweltaspekten der EU-Osterweiterung. So setzt sich das Netzwerk der Europaeischen Umweltraete, fuer das der Umweltrat zur Zeit die Aufgabe einer Koordinierungsstelle wahrnimmt, intensiv fuer die Staerkung der Umweltpolitikberatung in den Beitrittsstaaten ein.

Long-term monitoring of soil data is a task of the German state in the context of its national and international reporting obligations. A supraregional, statewide evaluation routine was developed, and test evaluations were carried out in selected sites. Measurements cover general site date and site-specific analytical parameters. A database was produced which covers 794 measuring sites from July 2000. [German] Im Rahmen der nationalen und internationalen Berichtspflichten des Bundes zum Bodenzustand, besteht die Notwendigkeit die Boden-Dauerbeobachtungsflaechen (DBF) der Laender auf Bundesebene fuer integrierende Auswertungen nutzbar zu machen. In einem vorangegangenen F+E Vorhaben (Organisation und Methodik des Bodenmonitorings, 1998) wurden zum ersten Mal Informationen ueber die Bodenmessnetze der Laender erhoben und auf ihre bundesweite Repraesentanz untersucht. Projektziel des vorliegenden Vorhabens war es zunaechst, die Datengrundlage durch eine Befragung der Laender zu aktualisieren. In einem weiteren Schritt sollten eine Konzeption fuer eine laenderuebergreifende Auwerteroutine erarbeitet, sowie eine Testauswertung an ausgewaehlten BDF durchgefuehrt werden. Aufbauend auf der Datengrundlage des o.g. Vorhabens wurden im Rahmen dieses Projektes die Daten aller BDF (Stand 12/99) ergaenzt und aktualisiert bzw. neue BDF erhoben. Dabei wurden sowohl die allgemeinen Standortdaten (Nutzung BDF-Typ, Boden- und Substrattyp, Koordinaten, etc.) sowie auch alle standortspezifischen Untersuchungsparameter (Bodenphysik, Bodenchemie, Bodenbiologie, Eintrags-/Austragsmessungen) erfasst und in einer Datenbank hinterlegt. Mit Stand Juli 2000 sind damit in Deutschland 794 BDF, die in Bodenmessnetzen integriert und nach den Vorgaben der Ad hoc AG BDF (LABO ad hoc AG BDF, 2000) betrieben werden, laenderuebergreifend dokumentiert.

Anhand eines Vergleichs der Diskussion in deutschen und französischen Printmedien wird dargelegt, wie im Sinne Foucaults eine diskursive Auseinandersetzung um die PID stattfindet. Die Arbeit besticht durch ihren klar strukturierten empirischen Teil, der eine geologische Karte des PID-Diskurses zeichnet. Damit wird auch die aktuelle Relevanz des Begriffs der Bio-Macht unterstrichen. Ein Schritt in Richtung einer Genealogie bleibt aber aus. So verbleibt die Studie eher auf der deskriptiven Ebene, das von Foucault stets geforderte Infragestellen von Machtbeziehungen wird nicht eingelöst, aber fundiertes Material für ein solches geliefert.With her study, Julia Diekämper shows how preimplantation genetic diagnosis (PGD has become a fiercely disputed topic of medial negotiations. Based on a comparison of the discussion in German and French print media, she illustrates (in Foucauldian terms how a discoursive controversy on PGD happens. The study impresses with its clearly structured empirical section, which draws a geological map of the PGD-discourse. This also underlines the current pertinence of the term biopower. However, the study fails to offer a step towards a genealogy. Thus, the study remains on the descriptive level; it does not implement the questioning of power relations, always postulated by Foucault, but it offers profound material for such questioning.

In diesem Artikel wird an drei Erfolgsmodellen dargestellt, wie das Zusammenwirken von Mathematik und Medizin eine Entwicklung hin zu patientenspezifischen Modellen auf Basis moderner medizinischer Bildgebung angestoßen hat, die in naher Zukunft dynamisch weiter Raum greifen wird. Dabei existiert ein Gleichklang der Interessen von Medizin und Mathematik: Beide Disziplinen wollen die Resultate schnell und zuverlässig. Für die Klinik heißt dies, dass notwendige Rechnungen in möglichst kurzer Zeit, und zwar auf dem PC, ablaufen müssen und dass die Resultate so genau und belastbar sein müssen, dass medizinische Entscheidungen darauf aufbauen können. Für die Mathematik folgt daraus, dass höchste Anforderungen an die Effizienz der verwendeten Algorithmen und die darauf aufbauende Software in Numerik und Visualisierung zu stellen sind. Allerdings ist es noch ein weiter Weg, bis anatomische und medizinisch brauchbare funktionelle Modelle auch nur für die wichtigsten Körperteile und die häufigsten Krankheitsfälle verfügbar sein werden. Führende Universitätskliniken könnten, als Zentren einer interdisziplinären Kooperation von Medizinern, Ingenieuren und Mathematikern, eine Vorreiterrolle dabei übernehmen, mehr Mathematik in der Medizin zu wagen. Dies wäre zweifellos ein wichtiger Schritt in Richtung auf eine individuelle quantitative Medizin, bei dem Deutschland die besten Voraussetzungen hätte, die Rolle des "Schrittmachers“ zu übernehmen.

In 1996 the two large heat storage tanks in Hamburg-Bramfeld (4,750 cubic metres) and Friedrichshafen-Wiggenhausen (12,000 cubic metres) were built out of concrete with an inner stainless steel lining. This was a big step towards economic efficiency. The research project ``Tight sealing of pit water storage tanks made out of pre-stressed concrete`` was launched by the BMBF in order to show that the concrete construction will not only bear loads but also ensure sealing. Building costs for underground hot water storage tanks could then be reduced by at least 25%. The first results of this research project are presented. The paper also contains recommendations for the further development of heat storage tanks built with pre-stressed concrete. (orig.)

Mit dem Bau dieser beiden Grossspeicher konnte ein richtungsweisender Schritt hin zur Wirtschaftlichkeit gemacht werden, wie man es in Studien vor 15 Jahren nicht fuer moeglich hielt. Mit dem BMBF - Forschungsvorhaben `Dichte Heisswasser - Waermespeicher aus Hochleistungsbeton` soll gezeigt werden, dass das Betontragwerk nicht nur Lasten abtragen sondern auch die Funktion der Abdichtung uebernehmen kann.

The radiation exposure of an unborn child should be principally avoided, whenever it is medically reasonably possible; therefore, the identification of pregnant patients is the first and the most important step in radiation protection of the unborn child. However, in cases of emergency saving the life of the patient has a higher priority than the radiation protection of the unborn child. In this review article, we present a longitudinal section through the national and international literature and guidelines as a basis for radiological management of a (possibly) pregnant patient. We also list some radiological procedures recommended in the literature for a series of maternal indications considering the contraindications of each method during pregnancy and radiation protection of the unborn child. (orig.) [German] Die Strahlenexposition eines ungeborenen Kindes ist prinzipiell, wann immer dieses medizinisch sinnvoll moeglich ist, zu vermeiden. Daher ist die Identifizierung der schwangeren Patientinnen der erste und wichtigste Schritt zum Strahlenschutz des ungeborenen Kindes.

In dieser Uebersichtsarbeit praesentieren wir einen Laengsschnitt durch die nationale und internationale Literatur und Leitlinien, die als Grundlage fuer das radiologische Management einer (moeglicherweise) schwangeren Patientin angewendet werden kann. Wir stellen auch einige in der Literatur empfohlene radiologische Verfahren fuer eine Reihe von Indikationen in der Schwangerschaft vor. Dabei werden sowohl die Kontraindikationen der jeweiligen Methode waehrend der Schwangerschaft als auch der Strahlenschutz des ungeborenen Kindes beruecksichtigt. (orig.)

After several years of preparatory research and in cooperation with several universities and organisations, Rohloel-Aufsuchungs AG were successful in recycling not only the flushings but also the cuttings of the drilling process, i.e. there is no need for dumping the residues. This is important as the regional authorities in that region are highly reluctant to grant permits for constructing new landfills, owing to the fact that it is a region of freshwater reserves for a large part of Europe and also a region much frequented by tourists. The 'waste-free drilling concept' has been applied for almost one year now. Further optimisation measures are projected. [German] Der Rohoel-Aufsuchungs AG ist es nach mehrjaehrigen Vorarbeiten gemeinsam mit verschiedenen Universitaeten und Institutionen gelungen, nicht nur die gesamte Bohrspuelung sondern auch die im Zuge des Bohrprozesses anfallenden Cuttings einer vollstaendigen Wiederverwertung zuzufuehren: Durch eine triviale Veraenderung des Spuelungschemismus, die den vollstaendigen Ersatz von Kaliumchlorid durch Kaliumkarbonate vorsieht, konnte das Bohrklein vom ''Abfall'' zum ''Wirtschaftsgut'' augewertet werden. Mit diesem entscheidenden Schritt wird der Bau neuer Borschlammdeponien ueberfluessig, deren behoerdliche Genehmigung ohnehin als unwahrscheinlich angesehen werden muss, zumal in dieser Region Grundwasserreserven fuer einen Teil Europas liegen und der Tourismus zur Haupteinnahmequelle dieses Gebietes zaehlt. Das ''abfallfreie Bohrkonzept'' wird bei der Rohoel-Aufsuchungs AG seit nahezu einem Jahr erfolgreich umgesetzt. Weitere Optimierungsschritte sind noch geplant. (orig.)

The Global Ozone Monitoring Experiment (GOME) was launched on 21 April 1995 as one of six scientific instruments on board the second European remote sensing satellite (ERS-2) of the ESA. The investigations presented here aimed at assessing and improving the accuracy of the GOME measurements of sun-standardized and absolute radiation density and the derived data products. For this purpose, the GOME data were compared with measurements pf terrestrial, airborne and satellite-borne systems. For scientific reasons, the measurements will focus on the medium and high latitudes of both hemispheres, although equatorial regions were investigated as well. In the first stage, operational data products of GOME were validated, i.e. radiation measurements (spectra, level1 product) and trace gas column densities (level2 product). [German] Am 21. April 1995 wurde das Global Ozone Monitoring Experiment (GOME) als eines von insgesamt sechs wissenschaftlichen Instrumenten an Bord des zweiten europaeischen Fernerkundungssatelliten (ERS-2) der ESA ins All gebracht. Das Ziel dieses Vorhabens ist es, die Genauigkeit der von GOME durchgefuehrten Messungen von sonnennormierter und absoluter Strahlungsdichte sowie der aus ihnen abgeleiteten Datenprodukte zu bewerten und zu verbessern. Dazu sollten die GOME-Daten mit Messungen von boden-, flugzeug- und satellitengestuetzten Systemen verglichen werden. Aus wissenschaftlichen Gruenden wird der Schwerpunkt auf Messungen bei mittleren und hohen Breitengraden in beiden Hemisphaeren liegen. Jedoch wurden im Laufe des Projektzeitraumes auch Regionen in Aequatornaehe untersucht. Im ersten Schritt sollen operationelle Datenprodukte von GOME validiert werden. Dieses sind Strahlungsmessungen (Spektren, Level1-Produkt) und Spurengas-Saeulendichten (Level2-Produkt). (orig.)

The pollution of air by nitrogen dioxide (NO{sub 2}) in cities is one of the central challenges of air pollution in Germany, in addition to the pollution of particulate matter (PM10). In cooperation with the British non-governmental organization ClientEarth, the German Environmental Aid (DUH) filed a lawsuit in November 2015 for exceeding air quality limits for NO{sub 2}. The cities of Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Cologne and Bonn are affected. Here, citizens are constantly exposed to high air pollution. Because of the excess of the NO{sub 2} limits at all traffic-related measuring stations in Berlin, the DUH initiated legal steps and filed a lawsuit too in June 2016. With the lawsuits, DUH wants to promote the implementation of measures to reduce NO{sub 2} in Germany.

Die bestehenden Angebote lassen sich in drei Typen gliedern: 1 Kommerzielle Prüfungen im Kontext von Weiterbildungsangeboten, 2 wissenschaftliche Tests im Kontext empirischer Studien sowie 3 spielerische Tests und Quizzes im Kontext von Sensibilisierungskampagnen. Ausgewählte Angebote werden vorgestellt und in Bezug auf ihre Brauchbarkeit für praktische Medienarbeit diskutiert. Als Ergänzung und Erweiterung des bestehenden Angebots wird der schweizerische Medienprofis-Test vorgestellt. Dabei handelt es sich um einen spielerischen Test, der frei zugänglich und empirisch validiert ist. Der Test umfasst fünf Themenbereiche: 1. Digitalisierung und Computerisierung, 2. Informationsfreiheit und Glaubwürdigkeit, 3. Sex, Gewalt und Jugendschutz, 4. Neue Geschäftsmodelle und Kommerz sowie 5. Personalisierung und Datenschutz. Die abgefragten Kompetenzen orientieren sich darüber hinaus am Modullehrplan «Medien & Informatik» des neuen deutschschweizerischen Lehrplans 21. Die von Experten validierten Items wurden anhand einer Stichprobe von Schülerinnen und Schülern der 3. bis 8. Klassen erprobt und mittels Raschmodell skaliert. Lehrpersonen können den Test im Klassenverband durchführen und erhalten dabei neben aggregierten Ergebnissen auch Empfehlungen für passende Unterrichtsmaterialien. Der Medienprofis-Test ist ein erster Schritt, ein standardisiertes und validiertes Messinstrument zur Verfügung zu stellen und die Diskussion um die Ausprägungen der Medienkompetenz mit empirisch Daten zu bereichern.

Blunt chest trauma is associated with high morbidity and mortality. Consequently, all patients should be evaluated radiologically after blunt chest trauma to allow timely and appropriate treatment. Conventional chest radiographs and computed tomography (CT) are proven modalities with which to evaluate patients after blunt chest trauma. Over the last several years extended focused assessment with sonography for trauma (eFAST) has gained increasing importance for the initial assessment of seriously injured patients. In the acute phase of severely injured patients eFAST examinations are helpful to exclude pneumothorax, hemothorax and hemopericardium. Chest radiographs may also be used to diagnose a pneumothorax or hemothorax; however, the sensitivity is limited and CT is the diagnostic modality of choice to evaluate severely injured patients. (orig.) [German] Stumpfe Thoraxtraumen gehen mit einer hohen Morbiditaet und Mortalitaet einher. Daher sollten Patienten mit Verdacht auf ein stumpfes Thoraxtrauma rasch radiologisch untersucht werden, damit die entsprechenden therapeutischen Schritte zeitgerecht eingeleitet werden koennen. Zur Abklaerung von Patienten nach einem stumpfen Thoraxtrauma sind seit Jahren das konventionelle Lungenroentgen und die Computertomographie bewaehrte Verfahren. In den letzten Jahren hat die fokussierte Ultraschalluntersuchung (eFAST, Extended Focused Assessment with Sonography for Trauma) von schwerverletzten Patienten vermehrt an Bedeutung gewonnen. Durch eine eFAST-Untersuchung kann in der Akutphase rasch geklaert werden, ob bei dem Patienten ein therapiebeduerftiger Pneumothorax, Haematoperikard oder Haematothorax vorliegen. Auch das Lungenroentgen wird zur Diagnose eines Pneumothorax oder Haematothorax eingesetzt, wenngleich seine Sensitivitaet deutlich eingeschraenkt ist. Die CT ist das diagnostische Verfahren der Wahl, um v. a. Patienten mit einem schweren Thoraxtrauma abzuklaeren. (orig.)

The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil. The Hydrology Department of Brandenburgische Technische Universitaet Cottbus, on behalf of the Thuringian Environmental Authority, investigated the state of the art of discharge of precipitated water into natural soils. The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection. [German] Die Nutzung natuerlicher Boeden zur kostenguenstigen Beseitigung von Niederschlagswasser aber auch von schwachbelastetem Abwasser ist eine Variante der Abwasserbeseitigung, die zunehmend Antragsgegenstand in wasserrechtlichen Verfahren ist. Der Schutz des Grundwassers ist dabei in besonderem Masse zu beachten. Die Einschaetzung der Eignung dieser Variante ist Behoerden aufgrund unzureichender Aussagen zum Langzeitverhalten und zu Abbaueffekten waehrend der Bodenpassage derzeit nicht moeglich. Durch die THUeRINGER LANDESANSTALT FUeR UMWELT erhielt der Lehrstuhl Wassertechnik der Brandenburgischen Technischen Universitaet Cottbus den Auftrag, im Rahmen einer Literaturstudie, den gegenwaertigen Stand der schadlosen Versickerung von Niederschlagswasser in natuerlichen Boeden aufzuzeigen.

Full Text Available Sechs Jahre sind vergangen seit Deutschland am 24. Februar 2009 die Behindertenrechtskonvention der Vereinten Nationen (BRK, die die volle Teilhabe aller Menschen an der Gesellschaft als Menschenrecht festschreibt, ratifizierte. Bereits seit 2002 gibt es in Deutschland ein Behindertengleichstellungsgesetz (BGG, den barrierefreien Zugang zu Informations- und Kommunikationstechnologien regelt die Barrierefreie Informationstechnik-Verordnung (BITV. Aus Sicht des Gesetzgebers sind die Rahmenbedingungen gegeben, Barrierefreiheit gehört inzwischen zum gängigen Vokabular im öffentlichen und teils auch privatwirtschaftlichen Bereich. Längst möchte man meinen, es sei ein alter Hut, Barrierefreiheit als Kernanliegen zu thematisieren oder gar einzufordern. Dies betrifft auch den rasant wachsenden Bereich digitaler Medien, der Wissen und Bildung für jedermann verfügbar macht - oder machen sollte. Vor diesem Hintergrund stellen sich die Autoren der Frage, inwieweit Barrierefreiheit in den digitalen Angeboten wissenschaftlicher und öffentlicher Bibliotheken in Deutschland angekommen ist; ob diese Angebote tatsächlich von allen genutzt werden können. Ausgehend von rechtlichen Grundlagen und Normen werden Formate und Standards für barrierefreie Netzpublikationen an Beispielen diskutiert. Im Fokus stehen einerseits Werkzeuge zum Suchen und Finden digitaler Information (Kataloge und Rechercheoberflächen, andererseits Ausgabeformate digitaler Dokumente (wie XML, PDF, EPUB oder TEI. Den Abschluss bilden Empfehlungen für (Digitale Bibliotheken und deren Verbände, um Barrierefreiheit künftig zur Routine zu machen. Das Fazit: Barrierefreiheit muss gewollt, geplant und sinnvoll umgesetzt werden. Technische Komponenten sind ein wichtiger, doch meist erst der zweite Schritt.

Kundenfokus: Startpunkt für die digitale Transformation bei Stadtwerken

Science.gov (United States)

Fett, Perry; Küller, Philipp

Big Data, Internet der Dinge, Mobile Computing und soziale Medien - die modernen Informationstechnologien durchdringen den Alltag der meisten Menschen und lösen hierdurch eine digitale Transformation aus. Im Unternehmenskontext manifestiert sich die Digitalisierung durch eine neue Qualität der wissensbasierten Entscheidungsunterstützung und der Automatisierung bzw. Autonomisierung der Geschäftsprozesse. Für Stadtwerke gilt es nun, die Chancen der Digitalisierung zu ihren Gunsten zu nutzen. Ein Startpunkt könnte hierbei sein, wie Stadtwerke zukünftig mit ihren Kunden interagieren. Ausgelöst durch die Liberalisierung der Märkte rückt der Kunde heute stärker in den Mittelpunkt - die Energiewirtschaft steht nun vor der Herausforderung, dem Wettbewerb einen Schritt voraus zu sein und dem Kunden ein absolut positives Kundenerlebnis (Customer Experience) sowohl als Maßnahme zur Kundenbindung als auch zum Kundenaufbau zu bieten. Das vorliegende Kapitel zeigt hierfür die Erfolgskriterien für die gelungene Etablierung des Kundenfokus im eigenen Unternehmen auf. Mit dem Customer-Focus-Cycle-Modell von Fujitsu, angelehnt an den Deming-Kreislauf, wird ein allgemeingültiger Ansatz für ein mögliches Vorgehen beim Aufbau des Kundenfokus vorgestellt. Die sechs Phasen werden dabei anhand praktischer Beispiele erläutert und geben zudem Hinweise zu Methoden und Tools. Aus dem vorgestellten "Werkzeugkasten" wird ferner die Customer-Journey-Methode im Detail erläutert. Weiter soll das präsentierte Reifegradmodell Unternehmen dabei unterstützen, den eigenen Status quo festzustellen und die persönlichen Ziele auf dem Weg zur kundenzentrierten Organisation festzulegen.

Review Essay: Das dialogische Selbst zwischen simultaner Pluralität und Halt verleihenden Sprachpraktiken

Full Text Available "Das dialogische Selbst" von Frank-M. STAEMMLER ist ein wichtiger Beitrag zu einem dialogischen Menschenbild, das von verschiedenen Seiten als Alternative zur methodologischen Individualismus formuliert wird. Der Zusammenhang zwischen einer dialogischen Theorie des Selbst und konkreten therapeutischen Techniken wird einleuchtend hergestellt; klar wird dabei, dass dialogisches Denken eine Herausforderung an tradierte Denkmuster ist. Es sabotiert die Denkfigur der "abgelösten Vorgängigkeit" (BERTAU 2015 (von "Ich", "Selbst" zugunsten des je tatsächlichen Geschehens. Allerdings können Pluralität und Dynamik, Performativität und Gegenwärtigkeit des Geschehens ihrerseits nicht beliebig sein und bloß emergent, sie erfahren vielmehr eine Struktur, ohne die sie nicht (wieder- erkennbar wären. Wie das Verhältnis von Geschehen und Struktur zu denken ist, scheint mir eine der Kernfragen des dialogischen Denkens zu sein. Nach einer formalen Betrachtung und inhaltlichen Übersicht des Buchs diskutiere ich diese Frage entlang STAEMMLERs eigenen Ideen über zwei Themen: Pluralität und Sprache. Das Verhältnis von Geschehen und Struktur ist demnach über die sprachliche Form in der Zeit, über die Zeit, zu denken. Angeredetwerden von einem "Du", das immer auch das allgemeine "Man" (oder "Wir" stellvertritt, verleiht dem "Ich" als dialogischem Selbst Stabilität in der Vielfalt. Der Schritt zur Öffnung der Intersubjektivität ins Öffentliche wird damit als notwendiges Moment zur Überwindung des Individualismus angesehen.

Mit dem Konsensusstatement „praktische Fertigkeiten“ hat die GMA im Rahmen der Entwicklung des Nationalen Kompetenzbasierten Lernzielkatalogs Medizin (NKLM eine Referenz für deren Vermittlung entwickelt, die 290 Lernziele nach Organsystem, Typ (Kern- oder Wahlziel, Reifezeitpunkt der Studierenden und Lernzieltiefe gliedert. Durch den Abgleich eines umfangreichen und gut evaluierten studentischen Tutorienangebots mit dem Konsensusstatement soll einerseits der praktische Nutzen des Konsensusstatements analysiert und andererseits das Tutorienangebot selbst auf Vollständigkeit hin untersucht werden.Methodik: Vier Bewerter/-innen haben in einem ersten Schritt in zwei Gruppen alle Lernziele des Konsensusstatements durch eines der 48 angebotenen Tutorien unabhängig voneinander klassifiziert. Zwischen den Bewertern/-innen einer Gruppe wurde die Interrater-Reliabilität insgesamt und in Abhängigkeit vom Organsystem berechnet. In einem zweiten Schritt wurde Dissens in der Klassifikation durch Diskussion und Konsensfindung gelöst. Anschließend wurde die Abdeckung der Lernziele in der geforderten Tiefe durch das Tutorienangebot getrennt nach Lernzieltyp und Organsystem analysiert. Gründe für den initialen Dissens wurden protokolliert und thematisch gruppiert. Ergebnisse: Die Klassifikationen der beiden Bewerter/-innen korrelieren signifikant in moderater Stärke, die Stärke der Korrelation variiert in Abhängigkeit vom Organsystem und damit auch der Formulierung der einzelnen Lernziele. Nach Konsentierung ergab sich folgendes Bild: 66% aller Lernziele und 74% der Kernziele wurden durch das Tutorienangebot abdeckt. Der Grad der Abdeckung unterschied sich abhängig von Organsystem und Reifezeitpunkten

Conodonts, Calcichordates and the Origin of Vertebrates

Full Text Available Interpretation of early deuterostome evolution and relationships has been hampered by the lack of soft-part preservation in most groups. In addition, a recently revealed upside-down life orientation of vertebrates (the only real notoneuralians compared to other bilateral animals has been misinterpreted as evidence for a unique body design in all deuterostomes, misleading any search for relatives. Regarding echinoderms, the variety of body plans is confusing. The interpretation of some fossils with echinoderm-type calcite skeletons as “calcichordate” ancestors of chordates, however, involves a hypothetical reconstruction of an unusual body plan and a long series of hypothetical transitions. The number of necessary steps is much lower if cephalochordates (amphioxus or lancelet are derived directly from hemichordate enteropneusts. “Sensation interpretations” of fossils (Yunnanozoon, Cathaymyrus from Burgess Shale type deposits have added further confusion. Soft-part preservation of conodont animals, with V-shaped myomeres and a notochord, shows that they were segmented chordates, while probable eyes and teeth suggest that they were already on the vertebrate side. Die Interpretation früher Deuterostomia hinsichtlich ihrer Evolution und verwandtschaftlichen Beziehungen ist in den meisten Gruppen durch den Mangel an Weichkörpererhaltung sehr erschwert. Die kürzlich entdeckte Tatsache, daß Vertebraten, d. h. die einzigen echten Notoneuralia, im Gegensatz zu anderen bilateral symmetrischen Organismen eine mit ihrer ursprünglichen Oberseite nach unten gerichtete Lebensstellung einnehmen, hat zu der irrtümlichen Ansicht geführt, daß alle Deuostomia über einen im Tierreich einzigartigen Bauplan verfügen. Diese Interpretation brachte naturgemäß jede Suche nach Verwandtschaftsverhältnissen auf Abwege. Hinsichtlich der Echinodermata ist die bauplanmäßige Variation in der Tat verwirrend.

Since the publication of the draft ''Climate Protection Plan 2050'' and the ''Green Paper on Energy Efficiency'', it is clear that the Federal Government is focusing on the electrification of the heat and transport sector in order to increase the share of renewable energies in these sectors. This step is not uncontroversial, and represents a paradigm shift in science and politics, because the reduction of the cross electricity consumption move into the background. It is now necessary to clearly distinguish between the conventional power consumption, which must continue to be tested for energy savings and efficiency potential, and the new power consumption, here referred to as the coupling current, which is accepted in order to achieve the objectives of the energy transition. Since the consideration of the energy transition as a purely national project is too short, possible positive and negative effects of the European Union Emission Trading System (EU ETS) deserve particular attention with regard to this reorientation. [German] Spaetestens seit der Veroeffentlichung des Entwurfs zum ''Klimaschutzplan 2050'' und des ''Gruenbuch Energieeffizienz'' ist klar, dass die Bundesregierung auf die Elektrifizierung des Waerme- und Verkehrssektors setzt, um den Anteil der erneuerbaren Energien in diesen Sektoren zu steigern. Dieser Schritt ist nicht unumstritten und stellt einen Paradigmenwechsel in Wissenschaft und Politik dar, denn auf einmal rueckt die Senkung des Bruttostromverbrauchs in den Hintergrund. Es gilt jetzt, klar zu trennen zwischen dem herkoemmlichen Stromverbrauch, der weiterhin auf Energieeinspar- und -effizienzpotenziale hin untersucht werden muss, und dem neuen, hier Koppelstrom genannten Stromverbrauch, welcher in Kauf genommen wird, um die Ziele der Energiewende zu erreichen. Da die Betrachtung der Energiewende als rein nationales Projekt zu kurz greift, verdienen moegliche

The marine climate of the North Sea and Baltic Sea was simulated and analyzed with the aid of meteorological and oceanographic models. The KLINO project is a first step towards climate impact research as sensitivity studies of the models permit preliminary statements on the effects of potential changes of marine climate. The simulations covered several decades. The models used were: WAM for calculating the swell of the Atlantic and the two marginal seas; HAMSOM for climate-induced variations of the hydrographic parameters of the NOrth Sea and Baltic Sea; HAMSOM and REMO for interactive coupling between ocean and atmosphere; HYDROMOD for extreme and normal conditions in the offshore region. [German] Im Projekt KLINO wurde das derzeitige marine Klima (Wasserstaende und mittlerer Meeresspiegel, Seegang, Stroemungen und Schichtung) von Nord- und Ostsee in Kontrollexperimenten mit Hilfe meteorologischer und ozeanographischer Modelle simuliert und nach vollzogen. Das KLINO Projekt ist in die Arbeiten zur Klima-Regionalisierung bzw. als ein erster Schritt zur Klima-Impaktforschung einzustufen, da Sensitivitaetsstudien der Modelle bereits vorsichtige Aussagen ueber die Folgen moeglicher Aenderungen des marinen Klimas zulassen. Das WAM-Modell lieferte eine Klimatologie des Seeganges fuer den Atlantik und die beiden Randmeere. Die klimainduzierten Schwankungen der hydrographischen Parameter in Nord- und Ostsee wurden mit Hilfe des HAMSOM untersucht; eine interaktive Kopplung zwischen Ozean und Atmosphaere erfolgte mit den Regionalmodellen HAMSOM und REMO. Die Simulationen deckten hinreichend lange Zeitraeume (Dekaden) ab und wurden mit beobachteten bzw. aus meteorologischen Re-Analysen abgeleiteten Fluessen von Impuls, Waerme und Frischwasser angetrieben. Zur Initialisierung und Validierung der ozeanographischen Modelle wurden umfangreiche Beobachtungsdatensaetze fuer die Parameter Temperatur, Salzgehalt, Eis, Seegang und Oberflaechenauslenkung zusammengestellt

New sensors are being developed at a rapid pace. On their basis new functions are quickly implemented because of their importance for safety and convenience. One significant step will be made with the introduction of a 24 GHz platform - under the precondition of the frequency release - fulfilling a multi-usage concept for the sensors. They will form the 'Virtual Safety Belt' around the car, and warn the driver from obstacles and hazardous situations. Upon availability of high dynamic CMOS imager chips Video cameras will be introduced in vehicles. A stereo capable Computer platform with picture processing capability will explore the high potential of functions. Finally, sensor data fusion will improve significantly the performance of the systems. (orig.) [German] Sensoren zur Erfassung der Fahrzeugumgebung befinden sich bereits im Einsatz.

A framework for driver task analysis is derived from a model of the drivers information processing. The first step of the procedure (SAFE) is to divide a given driving task (e.g. left turning in a signalised intersection of a certain type) into subtasks. These subtasks are appointed to defined stretches of the road and the time structure of the subtasks is determined. For each subtask an analysis format is used, that organizes different requirements into perception, expectation, judgement, memory, decision and driver action. In a next step, typical driver errors are appointed to the subtasks. Afterwards the information gathered in the analysis procedure is compressed to ratings of the complexity and risk included in each subtask. After the crucial subtasks of a driving task have been determined, a list of those requirements that led to that rating can be compiled. These lists give the potential for aiding the driver e.g. by use of driver assistance systems. (orig.) [German] In den Verkehrswissenschaften existieren bislang keine verkehrsspezifischen Standardverfahren, die eine Anforderungsanalyse auf der Ebene der Fahraufgaben erlauben. Dieser Beitrag stellt die Grundzuege eines Verfahrens zur Fahraufgabenanalyse dar (SAFE: Situative Anforderungsanalyse von Fahraufgaben). Es basiert auf einer Modellvorstellung zu den Informationsverarbeitungsprozessen, die waehrend der Bewaeltigung der Fahraufgabe eine Rolle spielen. Der erste Schritt der Aufgabenanalyse besteht darin, eine ausgewaehlte Fahraufgabe (z.B. Linksabbiegen in einer ampelgeregelten Kreuzung bestimmten Typs) in Teilaufgaben zu zerlegen und eine zeitliche Strukturierung dieser Teilaufgaben vorzunehmen. Diese werden raeumlichen Segmenten zugeordnet, die nacheinander durchfahren werden muessen. Fuer jede Teilaufgabe erfolgt dann die eigentliche Anforderungsanalyse, die nach den Kapiteln Wahrnehmung, Erwartungsbildung, Beurteilung, Gedaechtnisprozesse, Entscheidung/Planung sowie Fahrzeugbedienung mit jeweils

Full Text Available Kritische Stadtforschung dient in Gestalt der „kritischen Stadtsoziologie“ gegenwärtig als Negativfolie für jene Stadtforschungsperspektive, die mit dem Postulat einer „Eigenlogik der Städte“ (EdS antritt. Eine (Selbst-Verständigung über konzeptionelle Grundlagen und forschungsstrategische Absichten einer kritischen Stadtforschung dagegen gibt es kaum. Ausgehend von dieser Beobachtung ist es das Ziel dieses Beitrags, zu einer Konturierung kritischer Stadtforschung beizutragen. Dafür skizzieren wir zunächst Eckpunkte der EdS-Perspektive. Anschließend wird ein Blick zurück auf den Klassiker Die Lage der arbeitenden Klasse in England (1845 von Friedrich Engels geworfen. Daran verdeutlichen wir drei Schritte in der Etablierung einer kritischen Haltung in der Stadtforschung: die Berücksichtigung der historisch-sozialen Voraussetzungen für gegenwärtige Stadtentwicklungsprozesse, die Analyse der städtischen Raum- und Sozialverhältnisse als krisen- und konfliktvermittelte und deshalb als dynamische Verhältnisse sowie die Konzeptionierung dieser Verhältnisse als veränderbar. An drei wiederkehrenden Diskussionsfeldern sozialwissenschaftlicher Stadtforschung schließlich verfolgen wir, wie einerseits die EdS-Perspektive sich dieser Themen annimmt und wie andererseits eine kritische Haltung im Umgang mit diesen Themen eingenommen werden kann. Für eine kritische Stadtforschung schlagen wir vor, (a „Stadt“ nicht als dauerhaft definiert und nicht als erklärend für sozialräumliche Verhältnisse zu begreifen, (b auch Städte als Räume zu konzipieren, die sich im gegenseitigen Wechselverhältnis mit Gesellschaft konstituieren, (c mit einem Konzept von Differenz, das Unterschiede sozial erklärt, zu arbeiten, wenn Städte als einzigartig erlebte Orte analysiert werden sollen.

Background: Ovarian suppression in the adjuvant treatment of perimenopausal women with breast cancer is an important option. The therapeutic goal can be accomplished by administration of GnRH-analogues, ovarectomy or radiocastration. Patients and methods: We describe the advantages and the therapy related side effects and compare the different treatment modalities with each other. Results: Because of its reversibility and patients' compliance GnRH-analogues seem to be advantageous especially in younger premenopausal women. When longer term side effects of artificially induced menopause are less important, therapeutic alternatives such as radiocastration or ovarectomy are effective without obvious superiority between these options. Conclusion: Even in the background of the increasing use of GnRH-analogues radiocastration remains still a therapeutic alternative because of its cost-effectiveness and feasibility. This accounts especially for peri- or premenopausal women above the age of 45. (orig.) [German] Hintergrund: Bei praemenopausalen Patienten mit rezeptorpositiven Mammakarzinomen stellt die ovarielle Suppression einen wichtigen Schritt in der adjuvanten Therapie dar. Neben den GnRH-Analoga kommen hierfuer die Ovarektomie oder die Radiomenolyse infrage. Patienten und Methode: Die vorliegende Arbeit stellt die Vorteile der einzelnen Therapieoptionen den therapiebedingten Nebenwirkungen gegenueber und vergleicht die Methoden untereinander. Ergebnisse: Wegen der Reversibilitaet und der Patientenakzeptanz sollten GnRH-Analoga besonders bei juengeren praemenopausalen Patientinnen angewendet werden. In der Differentialtherapie von Patientinnen, bei denen die Langzeitnebenwirkungen einer iatrogen induzierten Menopause weniger zu befuerchten sind, kommen auch die anderen Verfahren in Betracht. Hierbei stehen Radiomenolyse und Ovarektomie gleichwertig nebeneinander. Schlussfolgerung: Die differentialtherapeutische Entscheidung zu einer der Methoden sollte

Without knowing the associated emotions and personal problems, 70 to 75 years later an assessment of the facts is difficult. Therefore, the contribution under consideration is limited to the message of different sources.

Detailed knowledge of the geothermal properties (thermal conductivity and specific heat capacity) of the undergorund becomes more and more important with increasing exploitation of geothermal resources by deep vertical borehole heat exchangers or by seasonal storage installations. For this pilot study all existing thermal conductivity data of the Swiss Molasse were compiled and supplemented with new laboratory measurements on core and cutting samples from deep wells (2.5 to 3.0 W/mK). In a second step top-to-bottom thermal conductivity profiles were calculated from geophysical well logs. These profiles show a clear dependence on lithology and variations in thermal conductivity of up to 1 W/mK over 50-200 m thick intervals. In clay-rich lithofacies thermal conductivity is only slightly dependent on the sedimentary architecture, whereas, in sandy facies obvious distinctions are possible. The modelling of a theoretical 750 m long vertical borehole heat exchanger shows that the potential quality of extractable heat increases or decreases by up to 20% by varying the thermal conductivity with only {+-}0.5 W/mK.

[Deutsch] Fuer die Nutzung geothermischer Ressourcen mit tiefen Erdwaermesonden und saisonalen Speicheranlagen werden detaillierte Kenntnisse der geothermischen Eigenschaften (Waermeleitfaehigkeit und Waemekapazitaet) des Untergrundes zunehmend wichtig.

In einem zweiten Schritt wurden Waermeleitfaehigkeits-Profile mit geophysikalischen Bohr-Logs berechnet. Diese Profile zeigen eine deutliche Abhaengigkeit von der Lithologie mit einer Variation der Waermeleitfaehigkeit von bis zu 1 W/mK ueber 50-200 m maechtige Intervalle. In den tonigen Lithologien kann nur eine schwache Abhaengigkeit der Waermeleitfaehigkeit von der sedimentaeren

This article follows to an essay in the ZNER of 2011 (S. 121 et seq.) for the first Joint Practical Guide of the Federal Network Agency (BNetzA) and Federal Cartel Office (FCO) from the year 2010, in which the authors had attested authorities a good ''step towards to more competition ''. In the essay is examined and shown that the Joint practical guide from the year 2010 this target could meet and what effect the now in its second edition newly revised guidelines on competition to distribution networks may have. The revision of the guidelines will be given to municipalities further action assistance to the hand, but - with few exceptions - only reproduces the jurisprudence of the staked legal framework. One proposed solution for the more diverse existing problems remains undone, whereas new problem areas are put up in several places. Nevertheless, the will of the authorities is to recognize, to avoid legal problems in the concession process and net acquisitions from the outset. [German] Dieser Beitrag knuepft an einen Aufsatz in der ZNER 2011 (S. 121 ff.) zum ersten Gemeinsamen Leitfaden von Bundesnetzagentur (BNetzA) und Bundeskartellamt (BKartA) aus dem Jahre 2010 an, in dem die Autoren den Behoerden einen richtigen ''Schritt hin zu mehr Wettbewerb'' attestiert hatten. In der Abhandlung wird untersucht und dargestellt, ob der Gemeinsame Leitfaden aus dem Jahr 2010 diesem Ziel gerecht werden konnte und welche Auswirkungen der nunmehr in der zweiten Auflage neu ueberarbeitete Leitfaden auf den Wettbewerb um Verteilnetze haben kann. Die Ueberarbeitung des Leitfadens wird den Kommunen eine weitere Handlungshilfe an die Hand gegeben, die aber - bis auf wenige Ausnahmen - den durch die Rechtsprechung abgesteckten Rechtsrahmen nur wiedergibt. Ein Loesungsvorschlag fuer die noch vielfaeltig bestehenden Probleme unterbleibt, wohingegen an mehreren Stellen neue Problemfelder aufgemacht werden. Gleichwohl ist der Wille der Behoerden

Full Text Available [english] Background: With the reformed curriculum “4C”, the Medical Faculty of the University of Cologne has started to systematically plan practical skills training, for which Clerkship Maturity is the first step. The key guidelines along which the curriculum was development were developed by experts. This approach has now been validated. Materials and methods: Both students and teachers were asked to fill in a questionnaire regarding preclinical practical skills training to confirm the concept of Clerkship Maturity. Results and discussion: The Cologne training program Clerkship Maturity can be validated empirically overall through the activities of the students awaiting the clerkship framework and through the evaluation by the medical staff providing the training. The subjective ratings of the advantages of the training by the students leave room for improvement. Apart from minor improvements to the program, the most likely solution providing sustainable results will involve an over-regional strategy for establishing skills training planned as part of the curriculum.[german] Hintergrund: Mit dem Modellstudiengang Humanmedizin hat die Medizinische Fakultät der Universität zu Köln begonnen, die praktische Ausbildung, deren erster Schritt die „Famulaturreife“ ist, systematisch zu planen.

CO{sub 2}- emission in Switzerland need to be reduced over the next 50 years. In 1990, a first step towards improvement was taken by the Swiss Feseral Office of Energy by establishing the ``Energy 2000`` action plan. Apart from practical recommendations for general energy saving measures, this programme provides also clear objectives in respect to increased and more effecient utilization of indigenious and renewable energy resources. Geothermal energy is one of these resources. In addition to the amount of geothermal heat delivered in 1990, it is planned to produce a further 170 GWh of geothermal energy by the year 2000. This correesponnds to about 6% of a total of 3000 GWh which, it is envisaged, will be produced by all alternative heat resources together by the year 2000. Today, most geothermal energy is provided by shallow borehole heat exchangers. However, intensive development of wide ranging and innovative geothermal techniques is taking place at present. These R and D activities, as well as projects at present being realised, receive significant support from the Swiss Federal Office of Energy. (orig.) [Deutsch] In den kommenden 50 Jahren soll und muss CO{sub 2}-Emission in der Sweiz betraechtlich reduziert werden. Einen ersten Schritt dazu bildet das. im Jahre 1990 vom bundesamtes fuer Energiewirtschaft erarbeitete, Programm ``Energie 2000``. Nebst konkreten Vorschlaegen zum allgemeinen Energiesparen wurden in diesem programm auch Zielsetzungen fuer eine vermehrte, innovative und efficiente Nutzung von einheimischen und erneuerbaren Energieressourcen formuliert. Dazu zaelt auch die Geometrie. Zusaetzlich zur bereits im Jahre 1990 produzierten Waerme soll die Geometrie im Jahr 2000 ca. 170 GWh an Waermeenergie lifern. Das entspricht ca.6% der fuer das Jahr 2000 geplanten Gesamtalternativ- Energieproduktion von 3000 GWh. Bei der geothermischen Energieproduktion satmmt bis heute der groesste Anteil von untiefen Erdwaermesonden. Die Anwendung neuer und

With the establishment of its corporate image Ruhrkohle Bergbau AG has created the basis for the processes of change. One of the first steps in this direction was the organisational development process of the collieries. In the first phase the main emphasis was on the reduction of the hierarchy and the introduction of teamwork. The employees concerned were trained and assisted in accordance with their new tasks and competences. In the second phase of the change the main emphasis was more on the organisation with special consideration of the lower hierarchy levels. Greater orientation towards value creation was thus achieved. Meanwhile 50 TQM groups are working on the continuous improvement of the work processes within the framework of the `Total Quality Management` initiative at the Heinrich Robert colliery. The success of the intensive efforts in connection with TQM is reflected in the falling costs and the associated increase in profitability of the colliery. (orig.) [Deutsch] Mit der Einstellung des Unternehmensleitbildes hat die Ruhrkohle Bergbau AG die Grundlagen fuer Veraenderungsprozesse geschaffen. Einer der ersten Schritte in diese Richtung war der Organisationsentwicklungsprozess der Bergwerke. Ausgangsbasis hierzu waren umfangreiche Untersuchungen, bei denen unter Beteiligung der betroffenen Mitarbeiter Schwachstellen in der Organisation herausgearbeitet wurden. In der ersten Phase der Organisationsentwicklung lag der Schwerpunkt in der Beseitigung dieser Schwachstellen, die groesstenteils die Aufbaustruktur betrafen. Beispielhaft seien hier die Verflachung der Hierarchie und die Einfuehrung bereichsuebergreifender Teamarbeit genannt. Entsprechend ihren neuen Aufgaben und Kompetenzen wurden die betroffenen Mitarbeiter qualifiziert und unterstuetzt. In der zweiten Phase der Veraenderung wurde der Schwerpunkt mit besonderer Beruecksichtigung der unteren Hierarchieebenen mehr auf die Ablauforganisation gelegt. Damit gelang eine verstaerkte Orientierung zur

. Seit 20 Jahren werden somit stetig neue virtuelle Lernprogramme auch für die Histologie entwickelt. Entsprechende Entwicklungen haben dadurch die Lernmethoden der Studenten zum Wissenserwerb und zur Prüfungsvorbereitung beeinflusst. Die Lehre sollte Seminare, Vorlesungen und Laborarbeiten dementsprechend anpassen. Als einen ersten Schritt wurde eine Sammlung digitaler mikroskopisch-histologischer Bilder für die Studenten an der FSU Jena zur Verfügung gestellt. Das Ziel dieser Studie ist es den Stellenwert des konventionellen Lichtmikroskops im derzeitigen Selbststudium der Studenten der Human- und Zahnmedizin im Vergleich zu digitalen Medien herauszufinden. Dazu wurde eine Umfrage unter 172 Human- und Zahnmedizinstudenten an der Friedrich-Schiller-Universität Jena durchgeführt. Die Ergebnisse lassen einen deutlichen Unterschied mit 51% Nutzung neuer Medien gegenüber früheren ähnlichen Studien mit 5% Nutzung erkennen. Es zeigt, dass digitale Medien wie Internet und CD- oder computergestützte Lernprogramme sich beim Selbststudium der Studenten der Human- und Zahnmedizin als ein Konkurrenzsystem zum klassischen Lichtmikroskop entwickelten.

Purpose. Development of a concept for structured diagnostic imaging in patients with multiple trauma.Material and methods. Evaluation of data from a prospective trial with over 2400 documented patients with multiple trauma. All diagnostic and therapeutic steps, primary and secondary death and the 90 days lethality were documented.Structured diagnostic imaging of multiple injured patients requires the integration of an experienced radiologist in an interdisciplinary trauma team consisting of anesthesia, radiology and trauma surgery. Radiology itself deserves standardized concepts for equipment, personnel and logistics to perform diagnostic imaging for a 24-h-coverage with constant quality.Results. This paper describes criteria for initiation of a shock room or emergency room treatment, strategies for documentation and interdisciplinary algorithms for the early clinical care coordinating diagnostic imaging and therapeutic procedures following standardized guidelines. Diagnostic imaging consists of basic diagnosis, radiological ABC-rule, radiological follow-up and structured organ diagnosis using CT. Radiological trauma scoring allows improved quality control of diagnosis and therapy of multiple injured patients.Conclusion. Structured diagnostic imaging of multiple injured patients leads to a standardization of diagnosis and therapy and ensures constant process quality. (orig.) [German] Fragestellung.

Future dynamics in f(R) theories

International Nuclear Information System (INIS)

Mueller, D.; Andrade, V.C. de; Maia, C.; Reboucas, M.J.; Teixeira, A.F.F.

2015-01-01

The f(R) gravity theories provide an alternative way to explain the current cosmic acceleration without invoking a dark energy matter component used in the cosmological modeling in the framework of general relativity. However, the freedom in the choice of the functional forms of f(R) gives rise to the problem of the degeneracy among these gravity theories on theoretical and (or) observational grounds. In this paper we examine the question as to whether the future dynamics can be used to break the degeneracy between f(R) gravity theories by investigating the dynamics of spatially homogeneous and isotropic dust flat models in two f(R) gravity theories, namely the well known f(R) = R+αR n gravity and another byAviles et al., whose motivation comes from the cosmographic approach to f(R) gravity. We perform a detailed numerical study of the dynamics of these theories taking into account the recent constraints on the cosmological parameters made by the Planck Collaboration. We demonstrate that besides being useful for discriminating between these two f(R) gravity theories, the future dynamics technique can also be used to determine the finite-time behavior as well as the fate of the Universe in the framework of these f(R) gravity theories. There also emerges from our analysis the result that one still can have a dust flat FLRWsolution with a big rip, if gravity is governed by f(R) = R+αR n . We also show that FLRW dust solutions with f'' < 0 do not necessarily lead to singularities. (orig.)

The scalar-tensor f(R) theory of gravity is considered in the framework of a simple inhomogeneous space-time model. In this research we use the reconstruction technique to look for possible evolving wormhole solutions within viable f(R) gravity formalism. These f(R) models are then constrained so that they are consistent with existing experimental data. Energy conditions related to the matter threading the wormhole are analyzed graphically and are in general found to obey the null energy conditions (NEC) in regions around the throat, while in the limit f(R) = R, NEC can be violated at large in regions around the throat.

Principles and concept 1993 of the systemic cancer multistep therapy (sCMT). Extreme whole-body hyperthermia using the infrared-A technique IRATHERM 2000 - selective thermosensitisation by hyperglycemia - circulatory back-up by adapted hyperoxemia

Ardenne, M. von [Von Ardenne Inst. of Applied Medical Research, Dresden (Germany)

The so-called Cancer Multistep Therapy was conceived by the author in 1965. It is a combined modality treatment with 3 process steps: Whole-body hyperthermia, hyperglycemia and hyperoxemia. The original therapy concept was further developed into a systemic Cancer Multistep Therapy (sCMT) of high efficiency and selectivity. An outline follows of this therapy and the actual state of the sCMT concept as per 1993 (new in timing, dosage, technique). Knowledge of the synergetic-additive efficiency of various groups of cytostatics reacting to the effects of the main treatment process steps (WBH+HG+HO) led in 1974 to an extension of the sCMT concept by including chemotherapy. In addition, a radiotherapeutical treatment was included in this concept as cancer cells clearly show a higher sensibility to radiation while under the influence of sCMT. Following the sCMT treatment, the patient remains under observation on an intensive in-patient basis for 24 hours before he or she is discharged for out-patient post-treatment care. The systemic tolerance of sCMT with minimal side-effects has been proven with several 100 patients and results have been published as part of the phase-I study. A first evaluation of the efficacy of sCMT was documented in the same study. (orig.) [Deutsch] 1965 wurde vom Autor die sogenannte Krebs-Mehrschritt-Therapie konzipiert. Es handelt sich hierbei um eine kombinierte Behandlung, bestehend aus Ganzkoerperhyperthermie, Hyperglykaemie und Hyperoxaemie. Die Weiterentwicklung der aelteren Therapiekonzepte bis hin zu einer systemischen Krebs-Mehrschritt-Therapie (sKMT) hoher Effizienz und Selektivitaet wird skizziert und der heutige Stand des sKMT-Konzeptes 1993 dargestellt. Es wurde ein strahlentherapeutischer Schritt in das Konzept aufgenommen, da unter der Wirkung der Hauptschritte eine deutlich erhoehte Strahlensensibilitaet der Krebszellen gegeben ist. Somit besteht das sKMT-Konzept 1993 aus den Hauptschritten Hyperthermie, Hyperglykaemie

Auf der Basis dieser Parameter werden im naechsten Schritt die Schallwege mittels Raytracing (RT) simuliert. Zuletzt werden dieser RT-Simulation die Messdaten (A-Scans) von verschiedenen Sender- und Empfaengerpositionen zugeordnet und nach der SAFT-Methode (Synthetic Aperature Focusing Technique) zeitaufgeloest ueberlagert. Die Kombination aus inversem Verfahren, RT und SAFT gewaehrleistet auch in anisotropen Werkstoffen eine ortsrichtige Visualisierung der Fehler. Wir erlaeutern diese drei Verfahren und stellen die Pruefanordnung von Pruefkoerpern mit kuenstlichen Testfehlern vor.

Aims and Scope. German rendering plants produce 300,000 tons of animal fat per year. Until recently, these raw products have been in wide use as nutritional additive for cattle and other animals fodder but now they have been banned due to their assumed role in BSE infection. Therefore, alternative fields of usage are required. In this context the Deutsche Bundesstiftung Umwelt (DBU) is sponsoring a joint research project which deals with the production and testing of cooling lubricants based on animal fat esters. Methods. In a first step, characteristics and quality of the animal fat were analyzed and monitored for a whole year in order to identify e.g. seasonal variations. The investigations covered the following fat specific and trace analytical parameters: total contamination, sulfates ash, water content, peroxide number, iodine value, kinematical viscosity, neutralisation number (free fatty acids), fatty acid spectra, elements / heavy metals (Al, B, Ca, Cd, Cr, Cu, Fe, K, Mo, Mn, Na, Ni, P, Pb, S, Sn, V, W and Zn), polycyclic aromatic hydrocarbons, polychlorinated biphenyls, polychlorinated dibenzo-dioxins and polychlorinated dibenzofurans. Results. Valuable hints on the design of the technical process of fatty acid methylesters production were gained by regarding the fat specific parameters. (orig.) [German] Hintergrund und Ziel. Von den deutschen Tierkoerperbeseitigungsanstalten werden z.Z. rund 300.000 t/a technisches tierisches Fett produziert.

CD-40-assoziierten zellbiologischen Ansatz aktiviert. In vitro konnten so bereits erfolgreich Lymphomzellen abgetoetet werden. Erste Schritte in Richtung eines In-vivo-Einsatzes sind geplant. Die verbesserte Prognose vom Lymphompatienten in den letzten 20 Jahren beruht unter anderem auf Fortschritten in der bildgebenden Diagnostik. Verbesserungen auf dem Gebiet der (Farbduplex-)Sonographie haben dazu gefuehrt, dass nicht ausschliesslich Groessenkriterien, sondern auch Perfusionstyp und struktureller Aufbau zur Beurteilung eines Lymphknoten herangezogen werden koennen. Aehnliche Fortschritte gelten auch fuer die Computer- und besonders die Kernspintomographie. Hier bieten sogenannte lymphknotenspezifische Kontrastmittel und Fortschritte auf der Spulenentwicklung weitere Perspektiven. Aus nuklearmedizinischer Sicht haben sich durch Weiterentwicklung der funktionellen Bildgebung mittels Positronenemissionstomographie gerade in der Lymphomdiagnostik neue Moeglichkeiten ergeben. Sowohl beim Primaerstaging wie auch in der Rezidivdiagnostik, weisen erste Studien vielversprechende Ergebnisse auf. (orig.)

This thesis present an analysis of qualitative interviews with experts in the field of climate research in which the relation among science, policy and public is discussed. To begin, an overview of the methods and results of climate science is presented. Following, elements of the discourse among science, policy and public are presented in a manner that demonstrates the different ways to look at the problem of anthropogenic climate change. Subsequently, approaches of the sociology of science are introduced in which science is examined as a social process. Here the question is raised up to what extent climate research has taken a problem oriented perspective in which social and political criteria in the treatment of actual risks of global change are taken into account. The results of the analysis indicate that uncertainties in science led to different perspectives regarding the risks of anthropogenic climate change. In this way scientific knowledge itself becomes problematic. Communication of scientific results to policy and public poses a process which is stamped by individual values and preferences. This suggests the possibility that recognition of theories is increasingly determined by extra scientific criteria like resonance in the media and possibility of connection for political measures.

On March 2, 2004, the Heinz Maier-Leibnitz research neutron source (FRM-II) generated neutrons for the first time. This marked the most important step on the way to using FRM-II for scientific purposes. On this occasion, this unique research facility in the world was dedicated in a ceremony attended by approximately 1000 representatives of politics, industry, and science. The keynote speaker, Federal Minister of the Interior Otto Schily; Bavarian Minister President Edmund Stoiber; Professor Claus Weyrich (Member of the Executive Board of Siemens AG); Dr. Thomas Goppel (Bavarian State Minister for Science, Research, and Arts); Professor Wolfgang A. Herman (President of the Technical University of Munich); Hannelore Gabor (2nd Mayor of the host municipality of Garching); and Professor Winfried Petry (Scientific Director of FRM-II) underlined the great importance of FRM-II for science, research, medicine, and technology. FRM-II will not only fill the 'neutron gap', but create extremely brilliant working conditions thanks to its considerably higher neutron flux compared to that of its predecessor, the legendary Atomic Egg. After the first conceptual design studies starting in 1980, the ground breaking ceremony in August 1996, and the third partial permit issued at Easter of 2003, a unique tool is now available for modern science and for medical and technical applications.

The modified theories of gravity, especially the f(R) gravity, have attracted much attention in the last decade. This paper is devoted to exploring plane-symmetric solutions in the context of metric f(R) gravity. We extend the work on static plane-symmetric vacuum solutions in f(R) gravity already available in the literature [1, 2]. The modified field equations are solved using the assumptions of both constant and nonconstant scalar curvature. Some well-known solutions are recovered with power-law and logarithmic forms of f(R) models.

2008-01-01

We shall investigate the properties of a congruence of geodesics in the framework of Palatini f(R) theories. We shall evaluate the modified geodesic deviation equation and the Raychaudhuri's equation and show that f(R) Palatini theories do not necessarily lead to attractive forces. Also, we shall study energy condition for f(R) Palatini gravity via a perturbative analysis of the Raychaudhuri's equation.

Nonlinear evolution of f(R) cosmologies. I. Methodology

International Nuclear Information System (INIS)

Oyaizu, Hiroaki

2008-01-01

We introduce the method and the implementation of a cosmological simulation of a class of metric-variation f(R) models that accelerate the cosmological expansion without a cosmological constant and evade solar-system bounds of small-field deviations to general relativity. Such simulations are shown to reduce to solving a nonlinear Poisson equation for the scalar degree of freedom introduced by the f(R) modifications. We detail the method to efficiently solve the nonlinear Poisson equation by using a Newton-Gauss-Seidel relaxation scheme coupled with the multigrid method to accelerate the convergence. The simulations are shown to satisfy tests comparing the simulated outcome to analytical solutions for simple situations, and the dynamics of the simulations are tested with orbital and Zeldovich collapse tests. Finally, we present several static and dynamical simulations using realistic cosmological parameters to highlight the differences between standard physics and f(R) physics. In general, we find that the f(R) modifications result in stronger gravitational attraction that enhances the dark matter power spectrum by ∼20% for large but observationally allowed f(R) modifications. A more detailed study of the nonlinear f(R) effects on the power spectrum are presented in a companion paper.

THE LIFETIME AND POWERS OF FR IIs IN GALAXY CLUSTERS

International Nuclear Information System (INIS)

Antognini, Joe; Bird, Jonathan; Martini, Paul

2012-01-01

We have identified and studied a sample of 151 FR IIs found in brightest cluster galaxies (BCGs) in the MaxBCG cluster catalog with data from FIRST and NVSS. We have compared the radio luminosities and projected lengths of these FR IIs to the projected length distribution of a range of mock catalogs generated by an FR II model and estimate the FR II lifetime to be 1.9 × 10 8 yr. The uncertainty in the lifetime calculation is a factor of two, primarily due to uncertainties in the intracluster medium (ICM) density and the FR II axial ratio. We furthermore measure the jet power distribution of FR IIs in BCGs and find that it is well described by a log-normal distribution with a median power of 1.1 × 10 37 W and a coefficient of variation of 2.2. These jet powers are nearly linearly related to the observed luminosities, and this relation is steeper than many other estimates, although it is dependent on the jet model. We investigate correlations between FR II and cluster properties and find that galaxy luminosity is correlated with jet power. This implies that jet power is also correlated with black hole mass, as the stellar luminosity of a BCG should be a good proxy for its spheroid mass and therefore the black hole mass. Jet power, however, is not correlated with cluster richness, nor is FR II lifetime strongly correlated with any cluster properties. We calculate the enthalpy of the lobes to examine the impact of the FR IIs on the ICM and find that heating due to adiabatic expansion is too small to offset radiative cooling by a factor of at least six. In contrast, the jet power is approximately an order of magnitude larger than required to counteract cooling. We conclude that if feedback from FR IIs offsets cooling of the ICM, then heating must be primarily due to another mechanism associated with FR II expansion.

Experimental and theoretical investigations of the decays of 206Fr and 208Fr

International Nuclear Information System (INIS)

Ritchie, B.G.

1979-01-01

206 Fr and 208 Fr were mass separated and observed with large-volume semiconductor detectors in calibrated geometries. Alpha, gamma, and electron singles and gamma-gamma and gamma-electron coincidence data were taken. The alpha decay experiments permitted the determination of the alpha branching ratios for 206 208 Fr as well as 205 207 Fr. The method used includes the information obtained from the electron capture decay studies of those nuclei. The alpha branching ratios obtained are generally higher than those reported previously. Energies and half-lives are in general agreement with previous measurements. The alpha measurements also revealed the presence of a heretofore unobserved alpha-emitting isomer in 206 Fr. The isomer has a half-life of 0.7 +- 0.1 seconds, and the energy of the associated alpha decay is 6.930 +- 0.005 MeV. Gamma data taken with the alpha measurements suggest that the isomeric level is 531 keV above the 206 Fr ground state, with the associated alpha decay populating a level at 391 keV in the 202 At nucleus. Measured alpha branching ratios were analyzed with the Rasmussen reduced width formalism. All observed francium decays were deduced to be unhindered. This study produced detailed level schemes for 206 Rn and 208 Rn. The gamma and electron data permitted the determination of internal conversion coefficients, multipolarities, spins, and parities. It appears from systematics that two different bands of states above J/sup π/ = 4+ are populated by in-beam studies. The deduced level scheme of 208 Rn was studied in the interacting boson approximation (IBA) with the computer code PHINT. The level scheme is readily explained with this model up to around 2 MeV. Good agreement between theory and experiment was also obtained for 204 Rn and 206 Rn, but the limited detail in these decay schemes does not provide conclusive evidence for the applicability of the IBA. 28 figures, 10 tables

Dynamics of anisotropic power-law f(R) cosmology

2016-01-01

Modified theories of gravity have attracted much attention of the researchers in the recent years. In particular, the f(R) theory has been investigated extensively due to important f(R) gravity models in cosmological contexts. This paper is devoted to exploring an anisotropic universe in metric f(R) gravity. A locally rotationally symmetric Bianchi type I cosmological model is considered for this purpose. Exact solutions of modified field equations are obtained for a well-known f(R) gravity model. The energy conditions are also discussed for the model under consideration. The viability of the model is investigated via graphical analysis using the present-day values of cosmological parameters. The model satisfies null energy, weak energy, and dominant energy conditions for a particular range of the anisotropy parameter while the strong energy condition is violated, which shows that the anisotropic universe in f(R) gravity supports the crucial issue of accelerated expansion of the universe.

2018-02-01

Based on thermodynamics, we discuss the galactic clustering of expanding Universe by assuming the gravitational interaction through the modified Newton's potential given by f(R) gravity. We compute the corrected N-particle partition function analytically. The corrected partition function leads to more exact equations of state of the system. By assuming that the system follows quasi-equilibrium, we derive the exact distribution function that exhibits the f(R) correction. Moreover, we evaluate the critical temperature and discuss the stability of the system. We observe the effects of correction of f(R) gravity on the power-law behaviour of particle-particle correlation function also. In order to check the feasibility of an f(R) gravity approach to the clustering of galaxies, we compare our results with an observational galaxy cluster catalogue.

The level structures of 211 Fr, 212 Fr and 213 Fr have been observed to high spins, approx. 28(h/2π) (and excitation energies approx. 8 MeV) using a variety of gamma-ray spectroscopic techniques. The structure of these nuclides is discussed in terms of couplings of single particle states through empirical shell model calculations. Good agreement with experiment is obtained. In 212 Fr and 213 Fr core-excited configurations are required to explain the properties of the highest states. A number of long lived states were observed in each nucleus some of which decay by by enhanced E3 transitions. The E3 transition strengths are discussed

2002-01-01

In-depth investigation of (α-γ)-coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ-rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the (α-γ)-coincidences makes it possible to find the intensity of population of 221 Fr levels by the α decay and multipolarities of five weak γ-transitions. The conversion electron spectrum is investigated in the range of 5-24 keV with a high (some 20 eV) energy resolution. A new M1 type 10.6-keV γ-transition is found. The proposed 225 Ac decay scheme includes 31 excited 221 Fr states. Parities are established for 16 of them. Possible spin values are proposed for 221 Fr levels. Properties of excited 221 Fr states are satisfactorily described by the quasiparticle-phonon nuclear model without the assumption of static octupole deformation

International Nuclear Information System (INIS)

Chiba, Takeshi; Smith, Tristan L.; Erickcek, Adrienne L.

2007-01-01

It has been proposed that cosmic acceleration or inflation can be driven by replacing the Einstein-Hilbert action of general relativity with a function f(R) of the Ricci scalar R. Such f(R) gravity theories have been shown to be equivalent to scalar-tensor theories of gravity that are incompatible with Solar System tests of general relativity, as long as the scalar field propagates over Solar System scales. Specifically, the parameterized post-Newtonian (PPN) parameter in the equivalent scalar-tensor theory is γ=1/2, which is far outside the range allowed by observations. In response to a flurry of papers that questioned the equivalence of f(R) theory to scalar-tensor theories, it was recently shown explicitly, without resorting to the scalar-tensor equivalence, that the vacuum field equations for 1/R gravity around a spherically symmetric mass also yield γ=1/2. Here we generalize this analysis to f(R) gravity and enumerate the conditions that, when satisfied by the function f(R), lead to the prediction that γ=1/2

f(R) gravity and chameleon theories

We analyze f(R) modifications of Einstein's gravity as dark energy models in the light of their connection with chameleon theories. Formulated as scalar-tensor theories, the f(R) theories imply the existence of a strong coupling of the scalar field to matter. This would violate all experimental gravitational tests on deviations from Newton's law. Fortunately, the existence of a matter dependent mass and a thin-shell effect allows one to alleviate these constraints. The thin-shell condition also implies strong restrictions on the cosmological dynamics of the f(R) theories. As a consequence, we find that the equation of state of dark energy is constrained to be extremely close to -1 in the recent past. We also examine the potential effects of f(R) theories in the context of the Eoet-wash experiments. We show that the requirement of a thin shell for the test bodies is not enough to guarantee a null result on deviations from Newton's law. As long as dark energy accounts for a sizeable fraction of the total energy density of the Universe, the constraints that we deduce also forbid any measurable deviation of the dark energy equation of state from -1. All in all, we find that both cosmological and laboratory tests imply that f(R) models are almost coincident with a ΛCDM model at the background level.

Full text: Considerable attention has been given to nuclei with A = 220 - 230 recently. In this region there occurs transition from the spherical to the deformed nuclear shape, which gives rise to some specific features in the nuclear structure. In particular, negative parity levels with low excitation energies have been found in even-even nuclei from this region [1, 2]. One of the nuclei allowing experimental investigation of the above properties is 221 Fr. The nuclide 221 Fr is from the region of isotopes which does not include stable nuclei and thus it cannot be studied in several-nucleon transfer reactions. In addition, the neutron excess in this nucleus makes it impossible to study the nucleus in reactions with heavy ions. Experimental information on the 221 Fr level structure can only be gained from investigation of the 225 Ac (T 1/2 = 10 days) alpha decay or the 221 Rn (T 1/2 = 25 min) beta decay. In the latter case the possibilities of the investigation are restricted by difficulties in making of 221 Rn sources. Therefore, most information on the structure and properties of 221 Fr is derived from investigation of the 225 Ac α -decay [3]. In-depth investigation of ( α - γ )- coincidences at the 225 Ac decay is carried out. Twenty-one new weak γ - rays are found; 18 γ-rays earlier ascribed to the 225 Ac decay are not confirmed. The quantitative analysis of the ( α - γ )- coincidences makes it possible to find the intensity of 221 Fr levels by the decay and multipolarities of five weak γ -transitions. The conversion electron spectrum is investigated in the range of 5 † 24 keV with a high (some 20 eV) energy resolution. A new M1 type 10.6-keV γ-transition is found. The proposed 225 Ac decay scheme includes 31 excited 221 Fr states. Parities are established for 16 of them. Possible spin values are proposed for 221 Fr levels. Properties of excited 221 Fr states are satisfactorily described by the quasiparticle-phonon nuclear model without the

Constraint propagation equations of the 3+1 decomposition of f(R) gravity

2011-01-01

Theories of gravity other than general relativity (GR) can explain the observed cosmic acceleration without a cosmological constant. One such class of theories of gravity is f(R). Metric f(R) theories have been proven to be equivalent to Brans-Dicke (BD) scalar-tensor gravity without a kinetic term (ω = 0). Using this equivalence and a 3+1 decomposition of the theory, it has been shown that metric f(R) gravity admits a well-posed initial value problem. However, it has not been proven that the 3+1 evolution equations of metric f(R) gravity preserve the (Hamiltonian and momentum) constraints. In this paper, we show that this is indeed the case. In addition, we show that the mathematical form of the constraint propagation equations in BD-equilavent f(R) gravity and in f(R) gravity in both the Jordan and Einstein frames is exactly the same as in the standard ADM 3+1 decomposition of GR. Finally, we point out that current numerical relativity codes can incorporate the 3+1 evolution equations of metric f(R) gravity by modifying the stress-energy tensor and adding an additional scalar field evolution equation. We hope that this work will serve as a starting point for relativists to develop fully dynamical codes for valid f(R) models.

We introduce the idea of an effective dark matter halo catalog in f(R) gravity, which is built using the effective density field. Using a suite of high resolution N-body simulations, we find that the dynamical properties of halos, such as the distribution of density, velocity dispersion, specific angular momentum and spin, in the effective catalog of f(R) gravity closely mimic those in the cold dark matter model with a cosmological constant (ΛCDM). Thus, when using effective halos, an f(R) model can be viewed as a ΛCDM model. This effective catalog therefore provides a convenient way for studying the baryonic physics, the galaxy halo occupation distribution and even semianalytical galaxy formation in f(R) cosmologies.

inclination angle profile of the Grossglockner mountain is followed on the test stand with a speed of 55 km/h without overheating of the cooling system. After optimization of the cooler design and positioning, the new vehicle was able to meet the specifications while the first of the two vehicles only achieved 35 km/h without overheating of the cooling system. Finally, a theoretical investigation identified the measures that should be taken to achieve sufficient cooling in countries with hot climates, e.g. the USA. It was found that it would be sufficient to raise the coolant temperature from 90 C to about 110 C to ensure good performance in these climate zones. (orig.) [German] Ziel der vorliegenden Arbeit ist die thermodynamische Analyse und Optimierung eines Brennstoffzellensystems zum Antrieb von Kraftfahrzeugen. Der Fokus ist im Wesentlichen auf die Kuehlung des Brennstoffzellenstapelmoduls gelegt, wobei aufgrund der Vielzahl an Schnittstellen zwischen der Kuehlung und den anderen Teilsystemen (Wasserstoff- und Luftversorgung) auch eine ganzheitlichere Betrachtung erforderlich ist. Ausgangspunkt der Untersuchungen ist ein bestehendes Brennstoffzellenfahrzeug, anhand dessen in einem ersten Schritt experimentelle Untersuchungen auf Systempruefstaenden und im Klimawindkanal durchgefuehrt werden. Die gewonnenen Messdaten dienen zum einen der Darstellung des Ist-Zustands und zur Ermittlung des Grenzbereichs der Waermeabfuhr an die Umgebung ueber das Brennstoffzellen-Kuehlsystem. Zum anderen werden sie zur Validierung eines dynamischen Kuehlsystemsimulationsmodells herangezogen. Mittels dieses Simulationsmodells werden anschliessend im Rahmen von Sensitivitaetsanalysen die wesentlichen Einflussfaktoren zur Steigerung der Waermeabfuhr an die Umgebung ermittelt. Die daraufhin durchgefuehrten Optimierungen betreffen die Verschaltung der Systemkomponenten sowie deren Auslegung und Platzierung im Fahrzeugvorderwagen.

The signal vector is obtained and the space-time-frequency distribution matrix is formed by FrFT. Then, this distribution matrix is used instead of the traditional MUSIC covariance matrix to construct FrFT- MUSIC spectral function. Target speed is estimated by searching. Simulation results show that this algorithm has a high accuracy of parameter estimation and strong resistance to noise.

The spectroscopic characteristics of the yrast levels of Fr217 are determined. The level scheme up to a value of J = (39/2 + ) for angular momentum and parity is established. The production of the Fr217 nucleus in a heavy ion collision reaction was only possible by using a radioactive Pb210 target. The method for preparing the target is described. The Fr217 nucleus belongs to the category of nuclei showing octupole effects. Mass A = 217 seems to be the lower limit of the region where these effects occur [fr

f(R) gravity, torsion and non-metricity

International Nuclear Information System (INIS)

Sotiriou, Thomas P

2009-01-01

For both f(R) theories of gravity with an independent symmetric connection (no torsion), usually referred to as Palatini f(R) gravity theories, and for f(R) theories of gravity with torsion but no non-metricity, called U4 theories, it has been shown that the independent connection can actually be eliminated algebraically, as long as this connection does not couple to matter. Remarkably, the outcome in both cases is the same theory, which is dynamically equivalent with an ω 0 = -3/2 Brans-Dicke theory. It is shown here that even for the most general case of an independent connection with both non-metricity and torsion, one arrives at exactly the same theory as in the more restricted cases. This generalizes the previous results and explains why assuming that either the torsion or the non-metricity vanishing ultimately leads to the same theory. It also demonstrates that f(R) actions cannot support an independent connection which carries dynamical degrees of freedom, irrespective of how general this connection is, at least as long as there is no connection-matter coupling.

Development of Streptomyces sp. FR-008 as an emerging chassis

Directory of Open Access Journals (Sweden)

Qian Liu

2016-09-01

Full Text Available Microbial-derived natural products are important in both the pharmaceutical industry and academic research. As the metabolic potential of original producer especially Streptomyces is often limited by slow growth rate, complicated cultivation profile, and unfeasible genetic manipulation, so exploring a Streptomyces as a super industrial chassis is valuable and urgent. Streptomyces sp. FR-008 is a fast-growing microorganism and can also produce a considerable amount of macrolide candicidin via modular polyketide synthase. In this study, we evaluated Streptomyces sp. FR-008 as a potential industrial-production chassis. First, PacBio sequencing and transcriptome analyses indicated that the Streptomyces sp. FR-008 genome size is 7.26 Mb, which represents one of the smallest of currently sequenced Streptomyces genomes. In addition, we simplified the conjugation procedure without heat-shock and pre-germination treatments but with high conjugation efficiency, suggesting it is inherently capable of accepting heterologous DNA. In addition, a series of promoters selected from literatures was assessed based on GusA activity in Streptomyces sp. FR-008. Compared with the common used promoter ermE*-p, the strength of these promoters comprise a library with a constitutive range of 60–860%, thus providing the useful regulatory elements for future genetic engineering purpose. In order to minimum the genome, we also target deleted three endogenous polyketide synthase (PKS gene clusters to generate a mutant LQ3. LQ3 is thus an “updated” version of Streptomyces sp. FR-008, producing fewer secondary metabolites profiles than Streptomyces sp. FR-008. We believe this work could facilitate further development of Streptomyces sp. FR-008 for use in biotechnological applications.

In California there are already 350 MW{sub e} worth of solar thermal energy plants in operation on a more or less commercial basis. In these installations thermal oil in parabolic gutters is heated from 300 C to 400 C. The thermal oil passes its thermal energy on to a water vapour circuit via a heat exchanger. The water vapour circuit can also be heated with natural gas, for instance at night when solar energy is not available. However, as yet no existing plant fulfils all three of the following requirements: its construction should entail the lowest possible investment costs and it should be able to run without solar energy and without an expensive storage system; it should have the greatest possible efficiency, especially at times when solar energy is not available (e.g. at night); at the same time, the solar thermal energy should be harvested at the lowest possible temperature so as to make expensive concentrating equipment superfluous. These seemingly contradictory demands are now met by a new concept involving a combined gas and steam plant whose operation is based on the injection of water into the compressed air rather than on a high excess of air. This water is evaporated by solar thermal energy at temperatures below 170 C according to its partial pressure.

FK506 (tacrolimus), a macrolide compound with immunosuppressant activity, has been proven to have clinical importance and has been manufactured industrially since 1993 by using mutants with high FK506-production ability; these mutants have been developed from the wild strain Streptomyces tsukubaensis No. 9993. FR900525 is one of the by-products of FK506 production. However, there was no effective industrial method to separate FR900525 from FK506 due to the structural similarity between the two compounds. Therefore, reducing the level of FR900525 was a serious problem in the industrial strain A. In this study, we aimed to reduce the FR900525 production. We first determined that pipecolic acid level was a critical parameter for controlling FR900525 production in strain A. S-(2-Aminoethyl) l-cysteine (AEC)-resistant mutants has been reported to increase lysine productivity successfully in a variety of lysine-producing microorganisms. Therefore, next, we applied a selection of AEC-resistant mutants to enhance pipecolic acid biosynthesis. Finally, four AEC-resistant mutants were obtained from strain A using ultraviolet irradiation, and three of them showed less FR900525 productivity compared to the parental strain A. Our findings indicated that AEC resistance was effective phenotype marker for increasing pipecolic acid productivity and for reducing FR900525 production in S. tsukubaensis. Thus, our study provides an efficient method for reducing FR90025 level during FK506 biosynthesis. Copyright © 2017 The Society for Biotechnology, Japan. Published by Elsevier B.V.

A=225 implantation for $^{221}$Fr source for TRIUMF atom trap

CERN Multimedia

The FrPNC Collaboration is mounting an atom trap for parity violation experiments and precision spectroscopy on francium atoms at TRIUMF's ISAC facility. We would like to use ISOLDE's capability of simultaneously implanting A=225 (while another experiment runs online) to make a long-lived source feeding $^{221}$Fr for tests of the trap. $^{225}$Ra $\\beta$-decays to $^{225}$Ac, which then $\\alpha$-decays, producing 100 keV $^{221}$Fr t$_{1/2}$= 4.8 minute recoils. The implanted A=225 source would be shipped to TRIUMF, where it would be held for several minutes at a time a few mm from the same yttrium foil that normally receives the ISAC beam. SRIM calculations imply that 20% of the $^{221}$Fr will be implanted in a 1 cm diameter spot on the yttrium. Then the yttrium foil is moved to the trap and heated to release the Fr atoms, just as in normal ISAC online operation. A test implantation will be done at 10$^{7}$/sec production for 1 day, testing whether carbon cracking on the implantation foil in the mass separ...

We construct an F(R) gravity theory corresponding to the Weyl invariant two scalar field theory. We investigate whether such F(R) gravity can have the antigravity regions where the Weyl curvature invariant does not diverge at the Big Bang and Big Crunch singularities. It is revealed that the divergence cannot be evaded completely but can be much milder than that in the original Weyl invariant two scalar field theory.

We investigate the corresponding relation between f(R) gravity and holographic dark energy. We introduce a type of energy density from f(R) that has the same role as holographic dark energy. We obtain the differential equation that specifies the evolution of the introduced energy density parameter based on a varying gravitational constant. We discover the relation for the equation of state parameter for low redshifts that contains varying G correction.

Cosmological reconstruction of realistic modified F(R) gravities

International Nuclear Information System (INIS)

Nojiri, Shin'ichi; Odintsov, Sergei D.; Saez-Gomez, Diego

2009-01-01

The cosmological reconstruction scheme for modified F(R) gravity is developed in terms of e-folding (or, redshift). It is demonstrated how any FRW cosmology may emerge from specific F(R) theory. The specific examples of well-known cosmological evolution are reconstructed, including ΛCDM cosmology, deceleration with transition to phantom superacceleration era which may develop singularity or be transient. The application of this scheme to viable F(R) gravities unifying inflation with dark energy era is proposed. The additional reconstruction of such models leads to non-leading gravitational correction mainly relevant at the early/late universe and helping to pass the cosmological bounds (if necessary). It is also shown how cosmological reconstruction scheme may be generalized in the presence of scalar field.

Fujii, Sumio; Katoh, Atsushi; Sato, Kazujiro

2003-01-01

The 21st century society will be facing growing demand of energy, global environmental issues and concerns about fossil fuel exhaustion. In this society, it is essential to seek for a sustainable energy system to solve these energy-related concerns. In order to find ways for solving these problems, 'Feasibility Study on Commercialized FR Cycle System' was launched in 1999 as a joint research project of JNC, electric utilities, JAERI, CRIEPI etc. This project aims to build promising FR cycle technologies for the 21st century. Now, we are in the second phase (JFY 2001-2005) of this project. At the end of the second phase, we will propose promising concepts through applying innovative technologies. We started this Feasibility Study with defining the development target, which ended in five items; safety, economy, environmental burden, resource utilization and nuclear non-proliferation. These items should also serve as basic viewpoints to evaluate achievements of the study. This paper describes how we evaluate FR cycle options to come up with the final promising candidates. This paper also describes a prospective scenario to introduce FR cycle system, which shows how the FR cycle will be replacing existing LWRs by using limited natural uranium resource and spent fuels.

The discussions on the connection between gravity and thermodynamics attract much attention recently. We consider a static self-gravitating perfect fluid system in f(R) gravity, which is an important theory could explain the accelerated expansion of the universe. We first show that the Tolman-Oppenheimer-Volkoff equation of f(R) theories can be obtained by thermodynamical method in spherical symmetric spacetime. Then we prove that the maximum entropy principle is also valid for f(R) gravity in general static spacetimes beyond spherical symmetry. The result shows that if the constraint equation is satisfied and the temperature of fluid obeys Tolmans law, the extrema of total entropy implies other components of gravitational equations. Conversely, if f(R) gravitational equation hold, the total entropy of the fluid should be extremum. Our work suggests a general and solid connection between f(R) gravity and thermodynamics.

Robust approach to f(R) gravity

2011-01-01

We consider metric f(R) theories of gravity without mapping them to their scalar-tensor counterpart, but using the Ricci scalar itself as an ''extra'' degree of freedom. This approach avoids then the introduction of a scalar-field potential that might be ill defined (not single valued). In order to explicitly show the usefulness of this method, we focus on static and spherically symmetric spacetimes and deal with the recent controversy about the existence of extended relativistic objects in certain class of f(R) models.

Galaxy-galaxy weak gravitational lensing in f(R) gravity

Science.gov (United States)

Li, Baojiu; Shirasaki, Masato

2018-03-01

We present an analysis of galaxy-galaxy weak gravitational lensing (GGL) in chameleon f(R) gravity - a leading candidate of non-standard gravity models. For the analysis, we have created mock galaxy catalogues based on dark matter haloes from two sets of numerical simulations, using a halo occupation distribution (HOD) prescription which allows a redshift dependence of galaxy number density. To make a fairer comparison between the f(R) and Λ cold dark matter (ΛCDM) models, their HOD parameters are tuned so that the galaxy two-point correlation functions in real space (and therefore the projected two-point correlation functions) match. While the f(R) model predicts an enhancement of the convergence power spectrum by up to ˜ 30 per cent compared to the standard ΛCDM model with the same parameters, the maximum enhancement of GGL is only half as large and less than 5 per cent on separations above ˜1-2 h-1 Mpc, because the latter is a cross-correlation of shear (or matter, which is more strongly affected by modified gravity) and galaxy (which is weakly affected given the good match between galaxy autocorrelations in the two models) fields. We also study the possibility of reconstructing the matter power spectrum by combination of GGL and galaxy clustering in f(R) gravity. We find that the galaxy-matter cross-correlation coefficient remains at unity down to ˜2-3 h-1 Mpc at relevant redshifts even in f(R) gravity, indicating joint analysis of GGL and galaxy clustering can be a powerful probe of matter density fluctuations in chameleon gravity. The scale dependence of the model differences in their predictions of GGL can potentially allows us to break the degeneracy between f(R) gravity and other cosmological parameters such as Ωm and σ8.

The holographic bound in the scalar-tensor and f(R) gravities

International Nuclear Information System (INIS)

Firouzjaee, J.T.

2013-01-01

The holographic bound has been extended to the different theory of gravities such as scalar-tensor gravity and f(R) gravity according to the Noether charge definition of the entropy for a black hole surface. We have introduced some popular examples of the flat FRW cosmology in order to investigate holographic bound in scalar-tensor and f(R) gravity. Using the holographic bound, we put an additional constraint on scalar-tensor gravity and the f(R) gravity parameters. We also discuss the transformation from Jordan frame to Einstein frame. (orig.)

In this paper, we investigate the late-time cosmic acceleration in mimetic f(R, T) gravity with the Lagrange multiplier and potential in a Universe containing, besides radiation and dark energy, a self-interacting (collisional) matter. We obtain through the modified Friedmann equations the main equation that can describe the cosmological evolution. Then, with several models from Q(z) and the well-known particular model f(R, T), we perform an analysis of the late-time evolution. We examine the behavior of the Hubble parameter, the dark energy equation of state and the total effective equation of state and in each case we compare the resulting picture with the non-collisional matter (assumed as dust) and also with the collisional matter in mimetic f(R, T) gravity. The results obtained are in good agreement with the observational data and show that in the presence of the collisional matter the dark energy oscillations in mimetic f(R, T) gravity can be damped.

The previously introduced class of two-parametric phenomenological inflationary models in general relativity in which the slow-roll assumption is replaced by the more general, constant-roll condition is generalized to the case of f(R) gravity. A simple constant-roll condition is defined in the original Jordan frame, and exact expressions for a scalaron potential in the Einstein frame, for a function f(R) (in the parametric form) and for inflationary dynamics are obtained. The region of the model parameters permitted by the latest observational constraints on the scalar spectral index and the tensor-to-scalar ratio of primordial metric perturbations generated during inflation is determined.

Full Text Available Motivated by UV completion of general relativity with a modification of a geometry at high energy scale, it is expected to have an energy dependent geometry. In this paper, we introduce charged black hole solutions with power Maxwell invariant source in the context of gravity’s rainbow. In addition, we investigate two classes of F(R gravity’s rainbow solutions. At first, we study energy dependent F(R gravity without energy-momentum tensor, and then we obtain F(R gravity’s rainbow in the presence of conformally invariant Maxwell source. We study geometrical properties of the mentioned solutions and compare their results. We also give some related comments regarding thermodynamical behavior of the obtained solutions and discuss thermal stability of the solutions.

Constraining f(R gravity in solar system, cosmology and binary pulsar systems

Directory of Open Access Journals (Sweden)

Tan Liu

2018-02-01

Full Text Available The f(R gravity can be cast into the form of a scalar–tensor theory, and scalar degree of freedom can be suppressed in high-density regions by the chameleon mechanism. In this article, for the general f(R gravity, using a scalar–tensor representation with the chameleon mechanism, we calculate the parametrized post-Newtonian parameters γ and β, the effective gravitational constant Geff, and the effective cosmological constant Λeff. In addition, for the general f(R gravity, we also calculate the rate of orbital period decay of the binary system due to gravitational radiation. Then we apply these results to specific f(R models (Hu–Sawicki model, Tsujikawa model and Starobinsky model and derive the constraints on the model parameters by combining the observations in solar system, cosmological scales and the binary systems.

Existence of relativistic stars in f(R) gravity

International Nuclear Information System (INIS)

Upadhye, Amol; Hu, Wayne

2009-01-01

We refute recent claims in the literature that stars with relativistically deep potentials cannot exist in f(R) gravity. Numerical examples of stable stars, including relativistic (GM * /r * ∼0.1), constant density stars, are studied. As a star is made larger, nonlinear 'chameleon' effects screen much of the star's mass, stabilizing gravity at the stellar center. Furthermore, we show that the onset of this chameleon screening is unrelated to strong gravity. At large central pressures P>ρ/3, f(R) gravity, like general relativity, does have a maximum gravitational potential, but at a slightly smaller value: GM * /r * | max =0.345<4/9 for constant density and one choice of parameters. This difference is associated with negative central curvature R under general relativity not being accessed in the f(R) model, but does not apply to any known astrophysical object.

Inflation in the framework of f(R) modified gravity is revisited. We study the conditions that f(R) should satisfy in order to lead to a viable inflationary model in the original form and in the Einstein frame. Based on these criteria we propose a new logarithmic model as a potential candidate for f(R) theories aiming to describe inflation consistent with observations from Planck satellite (2015). The model predicts scalar spectral index 0.9615

Closed string tachyon driving f(R) cosmology

Wang, Peng; Wu, Houwen; Yang, Haitang

2018-05-01

To study quantum effects on the bulk tachyon dynamics, we replace R with f(R) in the low-energy effective action that couples gravity, the dilaton, and the bulk closed string tachyon of bosonic closed string theory and study properties of their classical solutions. The α' corrections of the graviton-dilaton-tachyon system are implemented in the f(R). We obtain the tachyon-induced rolling solutions and show that the string metric does not need to remain fixed in some cases. In the case with H( t=‑∞ ) = , only the R and R2 terms in f(R) play a role in obtaining the rolling solutions with nontrivial metric. The singular behavior of more classical solutions are investigated and found to be modified by quantum effects. In particular, there could exist some classical solutions, in which the tachyon field rolls down from a maximum of the tachyon potential while the dilaton expectation value is always bounded from above during the rolling process.

Distinguishing f(R) theories from general relativity by gravitational lensing effect

Energy Technology Data Exchange (ETDEWEB)

The post-Newtonian formulation of a general class of f(R) theories is set up in a third-order approximation. It turns out that the information of a specific form of f(R) gravity is encoded in the Yukawa potential, which is contained in the perturbative expansion of the metric components. Although the Yukawa potential is canceled in the second-order expression of the effective refraction index of light, detailed analysis shows that the difference of the lensing effect between the f(R) gravity and general relativity does appear at the third order when √(f''(0)/f{sup '}(0)) is larger than the distance d{sub 0} to the gravitational source. However, the difference between these two kinds of theories will disappear in the axially symmetric spacetime region. Therefore only in very rare case the f(R) theories are distinguishable from general relativity by gravitational lensing effect in a third-order post-Newtonian approximation. (orig.)

The work was conducted as a part of the JNC's Feasibility Study on Commercialized Fast Reactor Cycle Systems (the F/S)'. In the FY 2001, the work conducted in the JNC was summed up as the followings: Conceptual study on cost-benefit analysis for FR cycle R and D. Refinement on the evaluation procedure and improvement over operation efficiency. Cost-benefit analysis of the reference FR cycle and sensitivity analysis with the revised system. Cost-benefit analyses of R and Ds for various FR cycle candidate concepts including FR cycle concepts studied in the F/S phase 1. The work made it possible to evaluate the cost effectiveness of various FR cycle systems efficiently. The cost-benefit analysis, which is often used for the policy evaluation, is considered to be applicable to FR cycle system concepts in the F/S. (author)

A no-hair theorem for black holes in f(R) gravity

Science.gov (United States)

Cañate, Pedro

2018-01-01

In this work we present a no-hair theorem which discards the existence of four-dimensional asymptotically flat, static and spherically symmetric or stationary axisymmetric, non-trivial black holes in the frame of f(R) gravity under metric formalism. Here we show that our no-hair theorem also can discard asymptotic de Sitter stationary and axisymmetric non-trivial black holes. The novelty is that this no-hair theorem is built without resorting to known mapping between f(R) gravity and scalar–tensor theory. Thus, an advantage will be that our no-hair theorem applies as well to metric f(R) models that cannot be mapped to scalar–tensor theory.

Disentangling the f(R). Duality

International Nuclear Information System (INIS)

Broy, Benedict J.; Westphal, Alexander; Pedro, Francisco G.; Univ. Autonoma de Madrid

2014-11-01

Motivated by UV realisations of Starobinsky-like inflation models, we study generic exponential plateau-like potentials to understand whether an exact f(R)-formulation may still be obtained when the asymptotic shift-symmetry of the potential is broken for larger field values. Potentials which break the shift symmetry with rising exponentials at large field values only allow for corresponding f(R)-descriptions with a leading order term R n with 1 2 -term survives as part of a series expansion of the function f(R) and thus cannot maintain a plateau for all field values. We further find a lean and instructive way to obtain a function f(R) describing m 2 φ 2 -inflation which breaks the shift symmetry with a monomial, and corresponds to effectively logarithmic corrections to an R+R 2 model. These examples emphasise that higher order terms in f(R)-theory may not be neglected if they are present at all. Additionally, we relate the function f(R) corresponding to chaotic inflation to a more general Jordan frame set-up. In addition, we consider f(R)-duals of two given UV examples, both from supergravity and string theory. Finally, we outline the CMB phenomenology of these models which show effects of power suppression at low-l.

Reconstructing an f(R) model from holographic dark energy: using the observational evidence

International Nuclear Information System (INIS)

Saaidi, Kh; Aghamohammadi, A

2012-01-01

We investigate the correspondence relation between f(R) gravity and an interacting holographic dark energy (HDE). By obtaining the conditions needed for some observational evidence such as positive acceleration expansion of the Universe, crossing the phantom divide line and validity of the thermodynamics second law in an interacting HDE model and corresponding it with the f(R) model of gravity, we find a viable f(R) model that can explain the present Universe. We also obtain the explicit evolutionary forms of the corresponding scalar field, potential and scale factor of the Universe. (paper)

LOW-POWER RADIO GALAXIES IN THE DISTANT UNIVERSE: A SEARCH FOR FR I AT 1 < z < 2 IN THE COSMOS FIELD

International Nuclear Information System (INIS)

Chiaberge, Marco; Tremblay, Grant; Macchetto, F. Duccio; Sparks, W. B.; Capetti, Alessandro; Tozzi, Paolo

2009-01-01

We present a search for FR I radio galaxies between 1 < z < 2 in the COSMOS field. In absence of spectroscopic redshift measurements, the selection method is based on multiple steps which make use of both radio and optical constraints. The basic assumptions are that (1) the break in radio power between low-power FR Is and the more powerful FR IIs does not change with redshift, and (2) that the photometric properties of the host galaxies of low-power radio galaxies in the distant universe are similar to those of FR IIs in the same redshift bin, as is the case for nearby radio galaxies. We describe the results of our search, which yields 37 low-power radio galaxy candidates that are possibly FR Is. We show that a large fraction of these low-luminosity radio galaxies display a compact radio morphology that does not correspond to the FR I morphological classification. Furthermore, our objects are apparently associated with galaxies that show clear signs of interactions, at odds with the typical behavior observed in low-z FR I hosts. The compact radio morphology might imply that we are observing intrinsically small and possibly young objects that will eventually evolve into the giant FR Is we observe in the local universe. One of the objects appears as pointlike in Hubble Space Telescope (HST) images. This might belong to a population of FR I-QSOs, which however would represent a tiny minority of the overall population of high-z FR Is. As for the local FR Is, a large fraction of our objects are likely to be associated with groups or clusters, making them 'beacons' for high-redshift clusters of galaxies. Our search for candidate high-z FR Is we present in this paper constitutes a pilot study for objects to be observed with future high-resolution and high-sensitivity instruments such as the EVLA and ALMA in the radio band, HST/WFC3 in the optical and IR, James Webb Space Telescope in the IR, as well as future generation X-ray satellites.

Full Text Available This study focuses on isolation, screening and characterization of novel probiotics from gastrointestinal tract of free-range chicken (Gallus gallus domesticus. Fifty seven colonies were isolated and three isolates (FR4, FR9 and FR12 were selected and identified as Lactobacillus gasseri FR4, Bacillus tequilensis FR9 and L. animalis FR12 by 16S rRNA sequencing. Three strains were able to survive in stimulated acidic and bile conditions and inhibit the growth of pathogens. Especially, FR9 exhibited maximum inhibition against Listeria monocytogenes and none of them exhibited hemolytic activity. Native-PAGE revealed the presence of low molecular weight (3.4-5.0 KDa antimicrobial peptide. The peptide was further purified by Sephadex G-50 column and RP-HPLC using C18 column. N-terminal amino acid sequencing of antimicrobial peptide showed 100% consensus to antilisterial peptide SubtilosinA and SboA gene was amplified from FR9 genome. FR9 showed maximum aggregation activity, EPS production (85.46 mg/L and cholesterol assimilation (63.12 ± 0.05 µg/mL. Strong adhesion property (12.6% and pathogen invasion protection ability was revealed by B. tequilensis FR9 towards HCT-116 human colon carcinoma cell line. This is the first study to demonstrate antilisterial SubtilosinA production of B. tequilensis. Our results indicate that B. tequilensis FR9 strain furnish the essential characteristics of a potential probiotics and might be incorporated into human and animal food supplements.

Unifying inflation with dark energy in modified F(R) Horava-Lifshitz gravity

International Nuclear Information System (INIS)

Elizalde, E.; Saez-Gomez, D.; Nojiri, S.; Odintsov, S.D.

2010-01-01

We study FRW cosmology for a non-linear modified F(R) Horava-Lifshitz gravity which has a viable convenient counterpart. A unified description of early-time inflation and late-time acceleration is possible in this theory, but the cosmological dynamic details are generically different from the ones of the convenient viable F(R) model. Remarkably, for some specific choice of parameters they do coincide. The emergence of finite-time future singularities is investigated in detail. It is shown that these singularities can be cured by adding an extra, higher-derivative term, which turns out to be qualitatively different when compared with the corresponding one of the convenient F(R) theory.

Full Text Available We have computed the number of polarization modes of gravitational waves propagating in the Minkowski background in f(R gravity. These are three of two from transverse-traceless tensor modes and one from a massive trace mode, which confirms the results found in the literature. There is no massless breathing mode and the massive trace mode corresponds to the Ricci scalar. A newly defined metric tensor in f(R gravity satisfies the transverse-traceless (TT condition as well as the TT wave equation.

The coincidence problem in holographic f(R) gravity

It is well known that f(R) gravity models formulated in the Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. In this case, the scalar field couples with the matter sector and the coupling term is given by the conformal factor. We apply the holographic principle to such interacting models. In a spatially flat universe, we show that the Einstein frame representation of f(R) models leads to a constant ratio of energy densities of dark matter to dark energy.

Constraint on reconstructed f(R) gravity models from gravitational waves

Science.gov (United States)

Lee, Seokcheon

2018-06-01

The gravitational wave (GW) detection of a binary neutron star inspiral made by the Advanced LIGO and Advanced Virgo paves the unprecedented way for multi-messenger observations. The propagation speed of this GW can be scrutinized by comparing the arrival times between GW and neutrinos or photons. It provides the constraint on the mass of the graviton. f(R) gravity theories have the habitual non-zero mass gravitons in addition to usual massless ones. Previously, we show that the model independent f(R) gravity theories can be constructed from the both background evolution and the matter growth with one undetermined parameter. We show that this parameter can be constrained from the graviton mass bound obtained from GW detection. Thus, the GW detection provides the invaluable constraint on the validity of f(R) gravity theories.

Herbert Fröhlich a physicist ahead of his time

CERN Document Server

Hyland, G J

2015-01-01

This biography provides a stimulating and coherent blend of scientific and personal narratives describing the many achievements of the theoretical physicist Herbert Fröhlich. For more than half a century, Fröhlich was an internationally renowned and much respected figure who exerted a decisive influence, often as a ‘man ahead of his time’, in fields as diverse as meson theory and biology. Although best known for his contributions to the theory of dielectrics and superconductivity, he worked in many other fields, his most important legacy being the pioneering introduction quantum field-theoretical methods into condensed matter physics in 1952, which revolutionised the subsequent development of the subject. Gerard Hyland has written an absorbing and informative account, in which Herbert Fröhlich’s magnetic personality shines through.

f(R in Holographic and Agegraphic Dark Energy Models and the Generalized Uncertainty Principle

Directory of Open Access Journals (Sweden)

Barun Majumder

2013-01-01

Full Text Available We studied a unified approach with the holographic, new agegraphic, and f(R dark energy model to construct the form of f(R which in general is responsible for the curvature driven explanation of the very early inflation along with presently observed late time acceleration. We considered the generalized uncertainty principle in our approach which incorporated the corrections in the entropy-area relation and thereby modified the energy densities for the cosmological dark energy models considered. We found that holographic and new agegraphic f(R gravity models can behave like phantom or quintessence models in the spatially flat FRW universe. We also found a distinct term in the form of f(R which goes as R 3 / 2 due to the consideration of the GUP modified energy densities. Although the presence of this term in the action can be important in explaining the early inflationary scenario, Capozziello et al. recently showed that f(R ~ R 3 / 2 leads to an accelerated expansion, that is, a negative value for the deceleration parameter q which fits well with SNeIa and WMAP data.

Extension of loop quantum gravity to f(R) theories.

2011-04-29

The four-dimensional metric f(R) theories of gravity are cast into connection-dynamical formalism with real su(2) connections as configuration variables. Through this formalism, the classical metric f(R) theories are quantized by extending the loop quantization scheme of general relativity. Our results imply that the nonperturbative quantization procedure of loop quantum gravity is valid not only for general relativity but also for a rather general class of four-dimensional metric theories of gravity.

We select f(R) gravity models that undergo scale factor duality transformations. As a starting point, we consider the tree-level effective gravitational action of bosonic String Theory coupled with the dilaton field. This theory inherits the Busher's duality of its parent String Theory. Using conformal transformations of the metric tensor, it is possible to map the tree-level dilaton-graviton string effective action into f(R) gravity, relating the dilaton field to the Ricci scalar curvature. Furthermore, the duality can be framed under the standard of Noether symmetries and exact cosmological solutions are derived. Using suitable changes of variables, the string-based f(R) Lagrangians are shown in cases where the duality transformation becomes a parity inversion.

Wasserstoffenergienetz, um damit Energie untereinander tauschen zu koennen und mit Ueberschuessen handeln zu koennen, wird eine demokratische Reglobalisierung von unten bedeuten. Die Zeit der wenigen grossen Energiekonzerne wird von einer Epoche vieler kleiner, unabhaengiger Versorger abgeloest. Oekonomische, soziale und und oekologische Netzwerke werden entstehen als Teil eines gesamtweltlichen Organismus und ein neues Sicherheits- und Unabhaengigkeitsgefuehl aller Buerger hervorrufen. Die eindeutigen Vorteile von Wasserstoff bestehen darin, dass Wasserstoff ueberall existiert, unbegrenzt verfuegbar ist und keine schaedlichen Kohlendioxidemissionen produziert. Diese Energie wird auch erschwinglich fuer Laender, die heute keinen Zugang zu Energie und Wohlstand haben. Ja gerade die Entwicklungslaender koennten den ersten Schritt in die nachhaltige Wasserstoffnutzung machen mit Sonnenenergie als Katalysator. Die ersten Brennstoffzellen auf Waserstoff-Basis werden bereits vielseitig eingesetzt, jedoch ist die Wasserstofferzeugung immer noch teuer und der meiste Wasserstoff wird aus Erdgas und anderen fossilen Brennstoffen gewonnen. In absehbarer Zeit koennte Wasserstoff mit erneuerbaren Energien produziert und billiger werden. Selbst in den Vorstandsetagen fuehrender Energieunternehmen sowie bei politischen Entscheidungstraegern erfreut sich Jules Vernes Vision von einer Zukunft im Zeichen des Wasserstoffs grosser Aufmerksamkeit und sie bemuehen sich auch schon jetzt um.

Stability of the Einstein static universe in f(R, T) gravity

The Einstein static (ES) universe has played a major role in various emergent scenarios recently proposed in order to cure the problem of the initial singularity of the standard model of cosmology. In the model we address, we study the existence and stability of an ES universe in the context of f(R, T) modified theories of gravity. Considering specific forms of the f(R, T) function, we seek for the existence of solutions representing ES state. Using dynamical system techniques along with numerical analysis, we find two classes of solutions: the first one is always unstable of the saddle type, while the second is always stable so that its dynamical behavior corresponds to a center equilibrium point. The importance of the second class of solutions is due to the significant role they play in constructing non-singular emergent models in which the universe could have experienced past-eternally a series of infinite oscillations about such an initial static state after which it enters, through a suitable physical mechanism, to an inflationary era. Considering specific forms for the functionality of f(R, T), we show that this theory is capable of providing cosmological solutions which admit emergent universe (EU) scenarios. We also investigate homogeneous scalar perturbations for the mentioned models. The stability regions of the solutions are parametrized by a linear equation of state (EoS) parameter and other free parameters that will be introduced for the models. Our results suggest that modifications in f(R, T) gravity would lead to stable solutions which are unstable in f(R) gravity model. (orig.)

Generation of spherically symmetric metrics in f(R) gravity

Energy Technology Data Exchange (ETDEWEB)

Amirabi, Z.; Halilsoy, M.; Mazharimousavi, S.H. [Eastern Mediterranean University, Department of Physics, Gazimagusa (Turkey)

In D-dimensional spherically symmetric f(R) gravity there are three unknown functions to be determined from the fourth order differential equations. It is shown that the system remarkably may be integrated to relate two functions through the third one to provide a reduction to second order equations accompanied with a large class of potential solutions. The third function, which acts as the generator of the process, is F(R) = (df(R))/(dR). We recall that our generating function has been employed as a scalar field with an accompanying self-interacting potential previously, which is entirely different from our approach. Reduction of f(R) theory into a system of equations seems to be efficient enough to generate a solution corresponding to each generating function. As particular examples, besides the known ones, we obtain new black hole solutions in any dimension D. We further extend our analysis to cover non-zero energy-momentum tensors. Global monopole and Maxwell sources are given as examples. (orig.)

Probing the f(R) formalism through gravitational wave polarizations

Alves, M.E.S.; Miranda, O.D.; Araujo, J.C.N. de

2009-01-01

The direct observation of gravitational waves (GW) in the near future, and the corresponding determination of the number of independent polarizations, is a powerful tool to test general relativity and alternative theories of gravity. In the present work we use the Newman-Penrose formalism to characterize GWs in quadratic gravity and in a particular class of f(R) Lagrangians. We find that both quadratic gravity and the f(R) theory belong to the most general invariant class of GWs, i.e., they can present up to six independent polarizations of GWs. For a particular combination of the parameters, we find that quadratic gravity can present up to five polarizations states. On the other hand, if we use the Palatini approach for f(R) theories, GWs present only the usual two transverse-traceless polarizations such as in general relativity. Thus, we conclude that the observation of GWs can strongly constrain the suitable formalism for these theories.

The existence of a non-zero electric dipole moment (EDM) implies the violation of time reversal symmetry. As the time-reversal symmetry violation predicted by the Standard Model (SM) for the electron EDM is too small to be observed with current experimental techniques and any a non-zero EDM would indicate new physics beyond the SM. The tiny signal from the electron EDM is enhanced in the heavy atoms such as francium (Fr). We are constructing the laser-cooled Fr factory to search for the electron EDM.

Reduction of environmental impact by FR cycle deployment

International Nuclear Information System (INIS)

Katoh, Atsushi; Nakai, Ryodai

2005-03-01

In this report radioactive waste generations in terms of disposal volume or disposal field equivalent, and the radioactive toxicity of HLW are evaluated to clarify the promising nuclear scenario for the sake of realization of sustainable society in 21st century. This analysis was conducted based on the outcomes of the mass flow evaluation tool 'FAMILY-21' which calculates a material balance for TRU in the following scenarios. 1) LWR once-through scenario, 2) Pu partly recycling in LWR scenario, 3) Pu full recycling in LWR scenario, 4) FBR deployment scenario, 5) Interim storage scenario. The result shows that the cumulative area of low level radioactive waste (LLW) disposal field at 2150 in the FR cycle deployment scenario is 1.8 times larger than that in the LWR once-through scenario. The area of LLW disposal field at 2150 is a few km 2 in all the scenarios. In contrast, the cumulative area of high level radioactive waste (HLW) disposal field at 2150 in the FR cycle deployment scenario is less than half of that in the LWR once-through scenario. The area of HLW disposal field at 2150 is about 10 times of the area of LLW disposal field. Moreover, the FR deployment reduces the radioactive toxicity of HLW by U/TRU recycling, and shortens the period to decay under the natural Uranium toxicity level. Considering the area of radioactive waste disposal field and the radioactive toxicity of HLW, the advantage of the FR cycle deployment is indicated quantitatively from the viewpoint of the environmental burden reduction.

FR4-based electromagnetic energy harvester for wireless sensor nodes

Science.gov (United States)

Hatipoglu, G.; Ürey, H.

2010-01-01

Electromagnetic (EM) energy harvesting seems to be one of the most promising ways to power wireless sensors in a wireless sensor network. In this paper, FR4, the most commonly used PCB material, is utilized as a mechanical vibrating structure for EM energy harvesting for body-worn sensors and intelligent tire sensors, which involve impact loadings. FR4 can be a better material for such applications compared to silicon MEMS devices due to lower stiffness and broadband response. In order to demonstrate FR4 performance and broadband response, three moving magnet type EM generator designs are developed and investigated throughout the paper. A velocity-damped harvester simulation model is first developed, including a detailed magnetic model and the magnetic damping effects. The numerical results agree well with the experimental results. Human running acceleration at the hip area that is obtained experimentally is simulated in order to demonstrate system performance, which results in a scavenged power of about 40 µW with 15 m s-2 acceleration input. The designed FR4 energy scavengers with mechanical stoppers implemented are particularly well suited for nearly periodic and non-sinusoidal high- g excitations with rich harmonic content. For the intelligent tire applications, a special compact FR4 scavenger is designed that is able to withstand large shocks and vibrations due to mechanical shock stoppers built into the structure. Using our design, 0.4 mW power across a load resistance at off-resonance operation is obtained in shaker experiments. In the actual operation, the tangential accelerations as a result of the tire-road contact are estimated to supply power around 1 mW with our design, which is sufficient for powering wireless tire sensors. The normalized power density (NPD) of the designed actuators compares favorably with most actuators reported in the literature.

Exact solutions for scalar field cosmology in f(R) gravity

Maharaj, S. D.; Goswami, R.; Chervon, S. V.; Nikolaev, A. V.

2017-09-01

We study scalar field FLRW cosmology in the content of f(R) gravity. Our consideration is restricted to the spatially flat Friedmann universe. We derived the general evolution equations of the model, and showed that the scalar field equation is automatically satisfied for any form of the f(R) function. We also derived representations for kinetic and potential energies, as well as for the acceleration in terms of the Hubble parameter and the form of the f(R) function. Next we found the exact cosmological solutions in modified gravity without specifying the f(R) function. With negligible acceleration of the scalar curvature, we found that the de Sitter inflationary solution is always attained. Also we obtained new solutions with special restrictions on the integration constants. These solutions contain oscillating, accelerating, decelerating and even contracting universes. For further investigation, we selected special cases which can be applied with early or late inflation. We also found exact solutions for the general case for the model with negligible acceleration of the scalar curvature in terms of special Airy functions. Using initial conditions which represent the universe at the present epoch, we determined the constants of integration. This allows for the comparison of the scale factor in the new solutions with that for current stage of the universe evolution in the ΛCDM model.

The first observation of the prompt and the delayed γ transitions involving the high spin states in 210 Fr is reported. The decay of the high spin states and the isomeric levels of 210 Fr, identified for the first time from the known sequence of low-lying transitions found earlier in the α decay of 214 Ac, were studied. High spin states of the doubly-odd 210 Fr, which were produced by the fusion evaporation reaction 197 Au ( 16 O, xn) 213-x Fr, were populated and the subsequent emitted γ rays were detected through the high-sensitivity germanium clover detector array INGA. The level scheme up to yrast levels of 5.3 MeV excitation energy and ∼20(ℎ/2π) angular momentum could be established for the first time through γγ, γγΔT coincidence, and DCO ratio measurements. A new low-lying isomeric transition at E γ = 203(2) keV was observed. The half-life was measured to be T 1/2 = 41(2) ns. The measured half-life was compared with the corresponding single-particle estimate, based on the level scheme obtained from the experiment.

In this work we investigate the equilibrium configurations of white dwarfs in a modified gravity theory, namely, f(R, T) gravity, for which R and T stand for the Ricci scalar and trace of the energy-momentum tensor, respectively. Considering the functional form f(R, T) = R+2λT, with λ being a constant, we obtain the hydrostatic equilibrium equation for the theory. Some physical properties of white dwarfs, such as: mass, radius, pressure and energy density, as well as their dependence on the parameter λ are derived. More massive and larger white dwarfs are found for negative values of λ when it decreases. The equilibrium configurations predict a maximum mass limit for white dwarfs slightly above the Chandrasekhar limit, with larger radii and lower central densities when compared to standard gravity outcomes. The most important effect of f(R, T) theory for massive white dwarfs is the increase of the radius in comparison with GR and also f(R) results. By comparing our results with some observational data of massive white dwarfs we also find a lower limit for λ, namely, λ > -3 x 10{sup -4}. (orig.)

100-FR-3 groundwater/soil gas supplemental limited field investigation report

International Nuclear Information System (INIS)

1996-04-01

In 1993, a Limited Field Investigation (LFI) was conducted for the 100-FR-3 Operable Unit which identified trichloroethylene (TCE) as a contaminant of potential concern (COPC) (DOE-RL 1994). In groundwater samples collected for the LFI, TCE was detected in well 199-177-1 at a concentration exceeding the U.S. Environmental Protection Agency (EPA) maximum contaminant level (5 μg/L) and Washington State groundwater criteria (3 μg/L). With the concurrence of the EPA and the Washington State Department of Ecology (Ecology), a supplemental LFI was conducted to determine the extent and potential source of TCE groundwater contamination associated with the 100-FR-3 Operable Unit. This report summarizes the activities and results of the groundwater/soil gas supplemental LFI for the 100-FR-3 Operable Unit. The primary objective of this investigation was to assess the lateral distribution of TCE in shallow (3 to 5 ft below the water table) groundwater associated with the 100-FR-3 Operable Unit. The second objective was to assess soil gas (3 to 5 concentrations in the study area in an attempt to identify potential sources of TCE and develop a correlation between soil gas and groundwater concentrations). Finally, the third objective of the investigation was to refine the site conceptual model

Drip Irrigation Aided Phytoremediation for Removal of TCE FR-om Groundwater

International Nuclear Information System (INIS)

Wilde, E.W.

2003-01-01

Groundwater in D-Area at the Savannah River Site (SRS) is contaminated with trichloroethylene (TCE) and by-products resulting FR-om discharges of this organic solvent during past disposal practices. This contaminated groundwater occurs primarily at depths of 9 meters to 15 meters below ground surface, well below the depths that are typically penetrated by plant roots. The process investigated in this study involved pumping water FR-om the contaminated aquifer and discharging the water into overlying test plots two inches below the surface using drip irrigation. The field treatability study was conducted FR-om 8/31/00 to 4/18/02 using six 0.08 hectare test plots, two each containing pines, cottonwoods, and no vegetation (controls). The primary objective was to determine the overall effectiveness of the process for TCE removal and to determine the principal biotic and abiotic pathways for its removal. Results demonstrated that the process provides a viable method to remove TCE-contaminated groundwater. The data clearly showed that the presence of trees reduced volatilization of TCE FR-om the drip irrigation system to the atmosphere. Influent groundwater TCE concentrations averaging 89 mg/L were reduced to non-detectable levels (less than 5 mg/L) within the upper two feet of soil (rhizosphere)

Modified gravity is one of the potential candidates to explain the accelerated expansion of the universe. Current study highlights the materialization of anisotropic compact stars in the context of f(R, G) theory of gravity. In particular, to gain insight in the physical behavior of three stars namely, Her X1, SAX J 1808-3658 and 4U 1820-30, energy density, and radial and tangential pressures are calculated. The f(R, G) gravity model is split into a Starobinsky like f(R) model and a power law f(G) model. The main feature of the work is a 3-dimensional graphical analysis in which, anisotropic measurements, energy conditions and stability attributes of these stars are discussed. It is shown that all three stars behave as usual for positive values of the f(G) model parameter n. (orig.)

Keys to evaluating and comparing FR fabric

Enright, M. [Westex Inc., Chicago, IL (United States)

2008-07-15

Exposure to electric arc flashes can result in the ignition of clothing, and can kill people at distances of 10 feet. This article discussed recent standards and regulations passed to ensure that employees working on or near energized electrical equipment use protective clothing made of flame resistant (FR) fabrics. The codes will require companies to comply with CSA Standard Z462 and determine which protective garments and FR fabrics are available. Employers will also be required to perform flash hazard analyses in order to determine the potential energy of hazards. Flash hazard analyses are typically performed by calculating the potential incident energy of equipment. Protective clothing is required to meet corresponding hazard risk categories. The ASTM F1506 Standard was developed to provide minimum specifications for protective clothing. The standard requires that the fabric used in protective garments must be resistant to arc flashes of varying energy levels. Many companies are simplifying compliance to the standards by implementing uniform programs that meet the highest requirements of the Standards. Arc flash suits are then made available for tasks involving higher energy level equipment. It was concluded that it is important to identify potential hazards and obtain industry consensus standards before investing in FR protective clothing. 2 figs.

Copy number and haplotype variation at the VRN-A1 and central FR-A2 loci are associated with frost tolerance in hexaploid wheat.

The interaction between VRN - A1 and FR - A2 largely affect the frost tolerance of hexaploid wheat. Frost tolerance is critical for wheat survival during cold winters. Natural variation for this trait is mainly associated with allelic differences at the VERNALIZATION 1 (VRN1) and FROST RESISTANCE 2 (FR2) loci. VRN1 regulates the transition between vegetative and reproductive stages and FR2, a locus including several tandemly duplicated C-REPEAT BINDING FACTOR (CBF) transcription factors, regulates the expression of Cold-regulated genes. We identified sequence and copy number variation at these two loci among winter and spring wheat varieties and characterized their association with frost tolerance. We identified two FR-A2 haplotypes-'FR-A2-S' and 'FR-A2-T'-distinguished by two insertion/deletions and ten single nucleotide polymorphisms within the CBF-A12 and CBF-A15 genes. Increased copy number of CBF-A14 was frequently associated with the FR-A2-T haplotype and with higher CBF14 transcript levels in response to cold. Factorial ANOVAs revealed significant interactions between VRN1 and FR-A2 for frost tolerance in both winter and spring panels suggesting a crosstalk between vernalization and cold acclimation pathways. The model including these two loci and their interaction explained 32.0 and 20.7 % of the variation in frost tolerance in the winter and spring panels, respectively. The interaction was validated in a winter wheat F 4:5 population segregating for both genes. Increased VRN-A1 copy number was associated with improved frost tolerance among varieties carrying the FR-A2-T allele but not among those carrying the FR-A2-S allele. These results suggest that selection of varieties carrying the FR-A2-T allele and three copies of the recessive vrn-A1 allele would be a good strategy to improve frost tolerance in wheat.

Thermodynamic laws for generalized f(R) gravity with curvature-matter coupling

International Nuclear Information System (INIS)

Wu Yabo; Zhao Yueyue; Cai Ronggen; Lu Jianbo; Lu Junwang; Gao Xiaojing

2012-01-01

The first law and the generalized second law (GSL) of thermodynamics for the generalized f(R) gravity with curvature-matter coupling are studied in the spatially homogeneous, isotropic FRW universe. The research results show that the field equations of the generalized f(R) gravity with curvature-matter coupling can be cast to the form of the first law of thermodynamics with the so-called the entropy production terms dS ¯ and the GSL can be given by considering the FRW universe filled only with ordinary matter enclosed by the dynamical apparent horizon with the Hawking temperature. Furthermore, as a concrete example, by utilizing the GSL the constraints on the gravitational model with f 1 (R)=R+αR l and f 2 (R)=R m are also discussed. It is worth noting these results given by us are quite general and can degenerate to the ones in Einstein's general relativity and pure f(R) gravity with non-coupling and non-minimal coupling as special cases. Comparing with the case of Einstein's general relativity, the appearance of the entropy production term dS ¯ in the first law of thermodynamics demonstrates that the horizon thermodynamics is non-equilibrium one for generalized f(R) gravity with curvature-matter coupling, which is consistent with the arguments given in Akbar and Cai (2007) [13] and Eling et al. (2006) [18].

On Analytical Solutions of f(R) Modified Gravity Theories in FLRW Cosmologies

Science.gov (United States)

Domazet, Silvije; Radovanović, Voja; Simonović, Marko; Štefančić, Hrvoje

2013-02-01

A novel analytical method for f(R) modified theories without matter in Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetimes is introduced. The equation of motion for the scale factor in terms of cosmic time is reduced to the equation for the evolution of the Ricci scalar R with the Hubble parameter H. The solution of equation of motion for actions of the form of power law in Ricci scalar R is presented with a detailed elaboration of the action quadratic in R. The reverse use of the introduced method is exemplified in finding functional forms f(R), which leads to specified scale factor functions. The analytical solutions are corroborated by numerical calculations with excellent agreement. Possible further applications to the phases of inflationary expansion and late-time acceleration as well as f(R) theories with radiation are outlined.

Late time acceleration of the universe in f(R) gravity model

International Nuclear Information System (INIS)

Mukherjee, Ankan

2014-01-01

In this work, a new way to look at the nature of late time dynamics of the universe for f(R) gravity models using the contracted Bianchi Identity has been proposed. As the Einstein field equations contain derivatives of the curvature scalar R, the contracted Bianchi identity yields a second order nonlinear differential equation in H, the Hubble parameter. This equation is studied for two particular forms of f(R), and the late time behaviour of the model is discussed. (author)

Studying the highly bent spectra of FR II-type radio galaxies with the KDA EXT model

Science.gov (United States)

Kuligowska, Elżbieta

2018-04-01

Context. The Kaiser, Dennett-Thorpe & Alexander (KDA, 1997, MNRAS, 292, 723) EXT model, that is, the extension of the KDA model of Fanaroff & Riley (FR) II-type source evolution, is applied and confronted with the observational data for selected FR II-type radio sources with significantly aged radio spectra. Aim. A sample of FR II-type radio galaxies with radio spectra strongly bent at their highest frequencies is used for testing the usefulness of the KDA EXT model. Methods: The dynamical evolution of FR II-type sources predicted with the KDA EXT model is briefly presented and discussed. The results are then compared to the ones obtained with the classical KDA approach, assuming the source's continuous injection and self-similarity. Results: The results and corresponding diagrams obtained for the eight sample sources indicate that the KDA EXT model predicts the observed radio spectra significantly better than the best spectral fit provided by the original KDA model.

Development of FR fuel cycle in japan (1) development scope of fuel cycle technology

International Nuclear Information System (INIS)

Nakamura, H.; Funasaka, H.; Namekawa, T.

2008-01-01

A fast reactor (FR) cycle has a potential to realize a sustainable energy supply system that is harmonized with environment by fully recycling both uranium (U) and transuranium (TRU) elements. In Japan, a Feasibility Study on Commercialized FR Cycle Systems (FS) was launched in July 1999, and through two different study phases, a final report was presented in 2006. As a result of FS, a combined system of sodium-cooled FR with mixed-oxide (MOX) fuel, advanced aqueous reprocessing and simplified pelletizing fuel fabrication was considered to be most promising for commercialization. The advanced aqueous reprocessing system, which is called the New Extraction system for TRU recovery (NEXT), consists of a U crystallization process for the bulk of U recovery, a simplified solvent extraction process for residual U, plutonium (Pu) and neptunium (Np) without Pu partitioning and purification, and a process for recovering americium (Am) and curium (Cm) from the raffinate. The ratio of Pu/U concentration in the mother solution after crystallization is adequate for MOX fuel fabrication, and thus complicated powder mixing processes for adjusting Pu content in MOX fuel can be eliminated in the subsequent simplified fuel fabrication system. In this system, lubricant-mixing process can also be eliminated by adopting the advanced technology in which lubricant is coated on the inner surface of a die before fuel powder supply. Such a simplification could help us overcoming the difficulty to treat MA bearing fuel powders in a hot cell. Ministry of Education, Culture, Sports, Science and Technology (MEXT) reviewed these results of FS in 2006 and identified the most promising FR cycle concept proposed in the FS phase II study as a mainline choice for commercialization. According to such a governmental assessment, R and D activities of FR cycle systems were decided to be concentrated mainly to the innovative technology development for the mainline concept. The stage of R and D project was

Stellar configurations in f(R) theories of gravity

International Nuclear Information System (INIS)

Henttunen, K.; Multamaeki, T.; Vilja, I.

2008-01-01

We study stellar configurations and the space-time around them in metric f(R) theories of gravity. In particular, we focus on the polytropic model of the Sun in two specific cases: the f(R)=R-μ 4 /R model and a model with a stabilizing higher order term f(R)=R-μ 4 /R+βR 3 /(3μ 4 ). We show how the stellar configuration in the f(R) theory can, by appropriate initial conditions, be selected to be equal to that described by the Lane-Emden equation and how a simple scaling relation exists between the solutions. We also derive the correct solution analytically near the center of the star in f(R) theory. Previous analytical and numerical results are confirmed, indicating that the space-time around the Sun is incompatible with solar system constraints in the f(R)=R-μ 4 /R model. Numerical work shows that stellar configurations, with a regular metric at the center, lead to γ PPN ≅1/2 outside the star for both models, i.e., the Schwarzschild-de Sitter space-time is not the correct vacuum solution for such configurations. This shows that even when one fine-tunes the initial conditions inside a star such that the mass of the effective scalar in the equivalent scalar-tensor theory is large, γ PPN is still 1/2 outside the star. Conversely, by selecting the Schwarzschild-de Sitter metric as the outside solution, or equivalently setting the mass of the effective scalar to be large outside the star, we find that the stellar configuration is unchanged but the metric is irregular at the center. The possibility of constructing a f(R) theory compatible with the solar system experiments and possible new constraints arising from the radius-mass relation of stellar objects is discussed

IIn this paper, we determine regular black hole solutions using a very general f(R) theory, coupled to a nonlinear electromagnetic field given by a Lagrangian L{sub NED}. The functions f(R) and L{sub NED} are in principle left unspecified. Instead, the model is constructed through a choice of the mass function M(r) presented in the metric coefficients. Solutions which have a regular behaviour of the geometric invariants are found. These solutions have two horizons, the event horizon and the Cauchy horizon. All energy conditions are satisfied in the whole space-time, except the strong energy condition (SEC), which is violated near the Cauchy horizon.We present also a new theorem related to the energy conditions in f(R) gravity, re-obtaining the well-known conditions in the context of general relativity when the geometry of the solution is the same.

Cosmology of f(R) gravity in the metric variational approach

Science.gov (United States)

Li, Baojiu; Barrow, John D.

2007-04-01

We consider the cosmologies that arise in a subclass of f(R) gravity with f(R)=R+μ2n+2/(-R)n and n∈(-1,0) in the metric (as opposed to the Palatini) variational approach to deriving the gravitational field equations. The calculations of the isotropic and homogeneous cosmological models are undertaken in the Jordan frame and at both the background and the perturbation levels. For the former, we also discuss the connection to the Einstein frame in which the extra degree of freedom in the theory is associated with a scalar field sharing some of the properties of a “chameleon” field. For the latter, we derive the cosmological perturbation equations in general theories of f(R) gravity in covariant form and implement them numerically to calculate the cosmic microwave background (CMB) temperature and matter power spectra of the cosmological model. The CMB power is shown to reduce at low l’s, and the matter power spectrum is almost scale independent at small scales, thus having a similar shape to that in standard general relativity. These are in stark contrast with what was found in the Palatini f(R) gravity, where the CMB power is largely amplified at low l’s and the matter spectrum is strongly scale dependent at small scales. These features make the present model more adaptable than that arising from the Palatini f(R) field equations, and none of the data on background evolution, CMB power spectrum, or matter power spectrum currently rule it out.

Chameleon halo modeling in f(R) gravity

International Nuclear Information System (INIS)

Li Yin; Hu, Wayne

2011-01-01

We model the chameleon effect on cosmological statistics for the modified gravity f(R) model of cosmic acceleration. The chameleon effect, required to make the model compatible with local tests of gravity, reduces force enhancement as a function of the depth of the gravitational potential wells of collapsed structure and so is readily incorporated into a halo model by including parameters for the chameleon mass threshold and rapidity of transition. We show that the abundance of halos around the chameleon mass threshold is enhanced by both the merging from below and the lack of merging to larger masses. This property also controls the power spectrum in the nonlinear regime and we provide a description of the transition to the linear regime that is valid for a wide range of f(R) models.

Wormholes in viable f(R) modified theories of gravity and weak energy condition

Energy Technology Data Exchange (ETDEWEB)

Pavlovic, Petar [Universitaet Hamburg, II. Institut fuer Theoretische Physik, Hamburg (Germany); Sossich, Marko [University of Zagreb, Department of Physics, Faculty of Electrical Engineering and Computing, Zagreb (Croatia)

2015-03-01

In this work wormholes in viable f(R) gravity models are analyzed. We are interested in exact solutions for stress-energy tensor components depending on different shape and redshift functions. Several solutions of gravitational equations for different f(R) models are examined. The solutions found imply no need for exotic material, while this need is implied in the standard general theory of relativity. A simple expression for weak energy condition (WEC) violation near the throat is derived and analyzed. High curvature regime is also discussed, as well as the question of the highest possible values of the Ricci scalar for which the WEC is not violated near the throat, and corresponding functions are calculated for several models. The approach here differs from the one that has been common since no additional assumptions to simplify the equations have been made, and the functions in f(R) models are not considered to be arbitrary functions, but rather a feature of the theory that has to be evaluated on the basis of consistency with observations for the Solar System and cosmological evolution. Therefore in this work we show that the existence of wormholes without exotic matter is not only possible in simple arbitrary f(R) models, but also in models that are in accordance with empirical data.

Models of f(R) cosmic acceleration that evade solar system tests

International Nuclear Information System (INIS)

Hu, Wayne; Sawicki, Ignacy

2007-01-01

We study a class of metric-variation f(R) models that accelerates the expansion without a cosmological constant and satisfies both cosmological and solar-system tests in the small-field limit of the parameter space. Solar-system tests alone place only weak bounds on these models, since the additional scalar degree of freedom is locked to the high-curvature general-relativistic prediction across more than 25 orders of magnitude in density, out through the solar corona. This agreement requires that the galactic halo be of sufficient extent to maintain the galaxy at high curvature in the presence of the low-curvature cosmological background. If the galactic halo and local environment in f(R) models do not have substantially deeper potentials than expected in ΛCDM, then cosmological field amplitudes |f R | > or approx.10 -6 will cause the galactic interior to evolve to low curvature during the acceleration epoch. Viability of large-deviation models therefore rests on the structure and evolution of the galactic halo, requiring cosmological simulations of f(R) models, and not directly on solar-system tests. Even small deviations that conservatively satisfy both galactic and solar-system constraints can still be tested by future, percent-level measurements of the linear power spectrum, while they remain undetectable to cosmological-distance measures. Although we illustrate these effects in a specific class of models, the requirements on f(R) are phrased in a nearly model-independent manner

2009-01-01

We consider a brane world scenario in which the bulk action is assumed to have the form of a generic function of the Ricci scalar f(R) and derive the resulting Einstein field equation on the brane. In a constant curvature bulk a conserved geometric quantity appears in the field equations which can be associated with matter. We present spherically symmetric solutions which account for galaxy rotation curves in a specific form. Then cosmological solutions by assuming a specific form for f(R) are derived which can explain an accelerated expanding universe.

Exploring the liminality: properties of haloes and subhaloes in borderline f(R) gravity

Science.gov (United States)

Shi, Difu; Li, Baojiu; Han, Jiaxin; Gao, Liang; Hellwing, Wojciech A.

2015-09-01

We investigate the properties of dark matter haloes and subhaloes in an f(R) gravity model with |fR0| = 10-6, using a very-high-resolution N-body simulation. The model is a borderline between being cosmologically interesting and yet still consistent with current data. We find that the halo mass function in this model has a maximum 20 per cent enhancement compared with the Λ-cold-dark-matter (ΛCDM) predictions between z = 1 and 0. Because of the chameleon mechanism which screens the deviation from standard gravity in dense environments, haloes more massive than 1013 h-1 M⊙ in this f(R) model have very similar properties to haloes of similar mass in ΛCDM, while less massive haloes, such as that of the Milky Way, can have steeper inner density profiles and higher velocity dispersions due to their weaker screening. The halo concentration is remarkably enhanced for low-mass haloes in this model due to a deepening of the total gravitational potential. Contrary to the naive expectation, the halo formation time zf is later for low-mass haloes in this model, a consequence of these haloes growing faster than their counterparts in ΛCDM at late times and the definition of zf. Subhaloes, especially those less massive than 1011 h-1 M⊙, are substantially more abundant in this f(R) model for host haloes less massive than 1013 h-1 M⊙. We discuss the implications of these results for the Milky Way satellite abundance problem. Although the overall halo and subhalo properties in this borderline f(R) model are close to their ΛCDM predictions, our results suggest that studies of the Local Group and astrophysical systems, aided by high-resolution simulations, can be valuable for further tests of it.

The simplest non-minimal matter-geometry coupling in the f(R, T) cosmology

f(R, T) gravity is an extended theory of gravity in which the gravitational action contains general terms of both the Ricci scalar R and the trace of the energy-momentum tensor T. In this way, f(R, T) models are capable of describing a non-minimal coupling between geometry (through terms in R) and matter (through terms in T). In this article we construct a cosmological model from the simplest non-minimal matter-geometry coupling within the f(R, T) gravity formalism, by means of an effective energy-momentum tensor, given by the sum of the usual matter energy-momentum tensor with a dark energy contribution, with the latter coming from the matter-geometry coupling terms. We apply the energy conditions to our solutions in order to obtain a range of values for the free parameters of the model which yield a healthy and well-behaved scenario. For some values of the free parameters which are submissive to the energy conditions application, it is possible to predict a transition from a decelerated period of the expansion of the universe to a period of acceleration (dark energy era). We also propose further applications of this particular case of the f(R, T) formalism in order to check its reliability in other fields, rather than cosmology. (orig.)

Study of some chaotic inflationary models in f(R) gravity

Science.gov (United States)

Sharif, M.; Nawazish, Iqra

2018-04-01

In this paper, we discuss an inflationary scenario via scalar field and fluid cosmology for an anisotropic homogeneous universe model in f(R) gravity. We consider an equation of state which corresponds to a quasi-de Sitter expansion and investigate the effect of the anisotropy parameter for different values of the deviation parameter. We evaluate potential models like linear, quadratic and quartic models which correspond to chaotic inflation. We construct the observational parameters for a power-law model of f(R) gravity and construct the graphical analysis of tensor-scalar ratio and spectral index which indicates the consistency of these parameters with Planck 2015 data.

standardisieren. Auf Initiative der deutschsprachigen Skills Labs wurde der GMA-Ausschuss für praktische Fertigkeiten gegründet, der einen kompetenzbasierten Lernzielkatalog entwickelte, dessen Entstehung und Struktur hier beschrieben wird.Ziel des Kataloges ist es, die praktischen Fertigkeiten im Medizinstudium zu definieren und damit den Fakultäten eine rationale Planungsgrundlage für die zur Vermittlung praktischer Fertigkeiten notwendigen Ressourcen zu geben.Methodik: Aufbauend auf schon vorhandenen deutschsprachigen Lernzielkatalogen wurde mittels einem mehrfach iterativem Kondensationsprozesses, der der Erarbeitung von S1-Leitlinien entspricht, vorgegangen, um eine breite fachliche und politische Abstützung zu erhalten. Ergebnisse: Es wurden 289 verschiedene praktische Lernziele identifiziert, die zwölf verschiedenen Organsystemen, drei Grenzbereichen zu anderen Kompetenzbereichen und einem Bereich mit organsystemübergreifenden Fertigkeiten zugeordnet. Sie wurden drei verschiedenen zeitlichen und drei verschiedenen Tiefendimensionen zugeordnet und mit dem Schweizer und dem Österreichischem Pendant abgeglichen. Diskussion: Das vorliegende Konsensusstatement kann den deutschen Fakultäten eine Grundlage zur Planung der Vermittlung praktischer Fertigkeiten bieten und bildet einen wichtigen Schritt zu einem nationalen Standard medizinischer Lernziele.Blick in die Zukunft: Das Konsensusstatement soll einen formativen Effekt auf die medizinischen Fakultäten haben, ihre praktischen Unterrichtsinhalte entsprechend zu vermitteln und die Ressourcen danach zu planen.

the cardiac patient. (orig.) [German] Das Belastungs-EKG ist fuer die nicht invasive Erkennung der koronaren Herzkrankheit aufgrund seines im Vergleich zu allen anderen Methoden geringeren zeitlichen, personellen und apparativen Aufwands die diagnostische Massnahme der ersten Wahl. Bei nicht eindeutigem Belastungs-EKG oder bei Unfaehigkeit des Patienten, sich koerperlich zu belasten, kommt als naechster Schritt die Anwendung klinisch etablierter Verfahren, wie Stressechokardiographie oder alternative Myokardszintigraphie, in Betracht. Seit der ersten Beschreibung der Stressechokardiographie 1979 hat sich diese Untersuchungstechnik durch eine kontinuierliche Verbesserung von Bildqualitaet (''second harmonic imaging''), Auswerteverfahren (Quad-Screen-Analyse) und Aufzeichnungsmoeglichkeiten (digitale Bildspeicherung) in Bezug auf Zuverlaessigkeit und Durchfuehrbarkeit staendig verbessert. Damit konnten die Indikationsstellung und das Einsatzspektrum der Stressechokardiographie in der Ischaemiediagnostik unter Nutzung dynamischer und pharmakologischer Belastungsmodalitaeten auf Kosten nuklearmedizinischer Verfahren erweitert werden. Trotz der offensicht-lichen Vorteile der Stressechokardiographie (keine Strahlenbelastung, relativ preiswert, beliebig wiederholbar, schnelle Verfuegbarkeit) duerfen ihre Nachteile nicht uebersehen werden. Wichtigster Nachteil ist die Beurteilung der stressechokardiographischen Untersuchung nach visuellen (qualitativen) Kriterien, wodurch die die Reproduzierbarkeit ihrer Ergebnisse (Wandbemegungsanalyse) stark vom Training und der Erfahrung des Untersuchers abhaengig ist.

Standard cosmological evolution in the f(R) model to Kaluza-Klein cosmology

Aghmohammadi, A; Abolhassani, M R; Saaidi, Kh; Vajdi, A

2009-01-01

In this paper, using f(R) theory of gravity we explicitly calculate cosmological evolution in the presence of a perfect fluid source in four- and five-dimensional space-time in which this cosmological evolution in self-creation is presented by Reddy et al (2009 Int. J. Theor. Phys. 48 10). An exact cosmological model is presented using a relation between Einstein's gravity field equation components due to a metric with the same component from f(R) theory of gravity. Some physics and kinematical properties of the model are also discussed.

A Fröhlich effect and representational gravity in memory for auditory pitch.

Science.gov (United States)

Hubbard, Timothy L; Ruppel, Susan E

2013-08-01

Memory for the initial pitch of an auditory target that increased or decreased in auditory frequency was examined. Memory was displaced forward in the direction of pitch motion, and this is consistent with the Fröhlich effect previously observed for visual targets moving in visual physical space. The Fröhlich effect for pitch increased with faster target velocity and decreased if an auditory cue with the same pitch as the initial pitch of the target was presented before the target was presented. The Fröhlich effect was larger for descending pitch motion than for ascending pitch motion, and this is consistent with an influence of representational gravity. The data suggest that representation of auditory frequency space exhibits some of the same biases as representation of visual physical space, and implications for theories of attention in displacement and for crossmodal and multisensory representation of space are discussed. 2013 APA, all rights reserved

Type 316 FR stainless steel has been developed as a candidate material for fast breeder reactor of next century. For the structural integrity design of high temperature components including reactor vessel, long-term data and analysis method are investigated for the new 316 FR steel especially to evaluate its time-dependent low-cycle fatigue behavior. The present paper reports dependencies of fatigue life on the strain rate from 10 -2 to 10 -5 s -1 , and on the temperature dependencies from 500degC to 600degC. Data are analyzed by a parametric method formerly proposed by the authors. It is shown that the method has a good predictability of the fatigue life up to very low strain rate of 10 -6 s -1 .

X-ray study of a sample of FR0 radio galaxies: unveiling the nature of the central engine

Science.gov (United States)

Torresi, E.; Grandi, P.; Capetti, A.; Baldi, R. D.; Giovannini, G.

2018-06-01

Fanaroff-Riley type 0 radio galaxies (FR0s) are compact radio sources that represent the bulk of the radio-loud active galactic nuclei (AGN) population, but they are still poorly understood. Pilot studies on these sources have been already performed at radio and optical wavelengths: here we present the first X-ray study of a sample of 19 FR0 radio galaxies selected from the Sloan Digital Sky Survey/NRAO VLA Sky Survey/Faint Images of the Radio Sky at Twenty-cm sample of Best & Heckman, with redshift ≤0.15, radio size ≤10 kpc, and optically classified as low-excitation galaxies. The X-ray spectra are modelled with a power-law component absorbed by Galactic column density with, in some cases, a contribution from thermal extended gas. The X-ray photons are likely produced by the jet as attested by the observed correlation between X-ray (2-10 keV) and radio (5 GHz) luminosities, similar to Fanaroff-Riley type I radio galaxies (FRIs). The estimated Eddington-scaled luminosities indicate a low accretion rate. Overall, we find that the X-ray properties of FR0s are indistinguishable from those of FRIs, thus adding another similarity between AGN associated with compact and extended radio sources. A comparison between FR0s and low-luminosity BL Lacs rules out important beaming effects in the X-ray emission of the compact radio galaxies. FR0s have different X-ray properties with respect to young radio sources (e.g. gigahertz-peaked spectrum/compact steep spectrum sources), generally characterized by higher X-ray luminosities and more complex spectra. In conclusion, the paucity of extended radio emission in FR0s is probably related to the intrinsic properties of their jets that prevent the formation of extended structures, and/or to intermittent activity of their engines.

Sequence and annotation of the 314-kb MT325 and the 321-kb FR483 viruses that infect Chlorella Pbi.

Viruses MT325 and FR483, members of the family Phycodnaviridae, genus Chlorovirus, infect the fresh water, unicellular, eukaryotic, chlorella-like green alga, Chlorella Pbi. The 314,335-bp genome of MT325 and the 321,240-bp genome of FR483 are the first viruses that infect Chlorella Pbi to have their genomes sequenced and annotated. Furthermore, these genomes are the two smallest chlorella virus genomes sequenced to date, MT325 has 331 putative protein-encoding and 10 tRNA-encoding genes and FR483 has 335 putative protein-encoding and 9 tRNA-encoding genes. The protein-encoding genes are almost evenly distributed on both strands, and intergenic space is minimal. Approximately 40% of the viral gene products resemble entries in public databases, including some that are the first of their kind to be detected in a virus. For example, these unique gene products include an aquaglyceroporin in MT325, a potassium ion transporter protein and an alkyl sulfatase in FR483, and a dTDP-glucose pyrophosphorylase in both viruses. Comparison of MT325 and FR483 protein-encoding genes with the prototype chlorella virus PBCV-1 indicates that approximately 82% of the genes are present in all three viruses.

Confrontation of the Magnetically Arrested Disc Scenario with Observations of FR II Sources

Energy Technology Data Exchange (ETDEWEB)

Rusinek, Katarzyna; Sikora, Marek, E-mail: krusinek@camk.edu.pl [Nicolaus Copernicus Astronomical Center, Polish Academy of Sciences, Warsaw (Poland)

The main aim of our work was to check whether powers of jets in FR II radio galaxies (RGs) and quasars (QSOs) can be reproduced by the Magnetically Arrested Disc (MAD) scenario. Assuming that established in the recent numerical simulations of the MAD scenario the (H/R){sup 2} dependence of the jet production efficiency is correct, we demonstrate that in order to reproduce the observed jet powers in FR II sources: (i) accretion discs must be geometrically much thicker than the standard ones; (ii) and/or that the jet production is strongly modulated.

The power mechanism and accretion geometry for low-power FR 1 radio galaxies are poorly understood in comparison to those for Seyfert galaxies and QSOs. In this paper, we use the diagnostic power of the Ly α recombination line observed using the Cosmic Origins Spectrograph (COS) aboard the Hubble Space Telescope ( HST ) to investigate the accretion flows in three well-known, nearby FR 1s: M87, NGC 4696, and Hydra A. The Ly α emission line’s luminosity, velocity structure, and the limited knowledge of its spatial extent provided by COS are used to assess conditions within a few parsecs of the supermassive black hole in these radio-mode active galactic nuclei. We observe strong Ly α emission in all three objects with total luminosity similar to that seen in BL Lacertae objects. M87 shows a complicated emission-line profile in Ly α , which varies spatially across the COS aperture and possibly temporally over several epochs of observation. In both NGC 4696 and M87, the Ly α luminosities ∼10{sup 40} erg s{sup -1} are closely consistent with the observed strength of the ionizing continuum in Case B recombination theory and with the assumption of a near-unity covering factor. It is possible that the Ly α -emitting clouds are ionized largely by beamed radiation associated with the jets. Long-slit UV spectroscopy can be used to test this hypothesis. Hydra A and the several BL Lac objects studied in this and previous papers have Ly α luminosities larger than M87 but their extrapolated, nonthermal continua are so luminous that they overpredict the observed strength of Ly α , a clear indicator of relativistic beaming in our direction. Given their substantial space density (∼4 × 10{sup -3} Mpc{sup -3}), the unbeamed Lyman continuum radiation of FR 1s may make a substantial minority contribution (∼10%) to the local UV background if all FR 1s are similar to M87 in ionizing flux level.

Static spherically symmetric wormholes in f(R, T) gravity

Energy Technology Data Exchange (ETDEWEB)

Zubair, M.; Ahmad, Yasir [Institute Of Information Technology, Department of Mathematics, COMSATS, Lahore (Pakistan); Waheed, Saira [Prince Mohammad Bin Fahd University, Al Khobar (Saudi Arabia)

2016-08-15

In this work, we explore wormhole solutions in f(R, T) theory of gravity, where R is the scalar curvature and T is the trace of stress-energy tensor of matter. To investigate this, we consider a static spherically symmetric geometry with matter contents as anisotropic, isotropic, and barotropic fluids in three separate cases. By taking into account the Starobinsky f(R) model, we analyze the behavior of energy conditions for these different kinds of fluids. It is shown that the wormhole solutions can be constructed without exotic matter in few regions of space-time. We also give the graphical illustration of the results obtained and discuss the equilibrium picture for the anisotropic case only. It is concluded that the wormhole solutions with anisotropic matter are realistic and stable in this theory of gravity. (orig.)

Study on creep-fatigue life improvement and life evaluation of 316FR stainless steels

2000-01-01

Creep rupture and creep-fatigue interaction tests were conducted at 550deg C for modified 316FR austenitic stainless steels in order to improve the creep-fatigue lives. Reducing the carbon contents from 0.01% to 0.002 or 0.003% and finning the grain size were effective for increasing the creep-fatigue lives and the creep rupture ductilities. From these results, an estimation method of the creep-fatigue lives by using the creep rupture ductilities in the modified 316FR steels was proposed. (author)
