This report comprises six single lectures given at an information meeting organized by the Institut fuer Reaktortechnik der Technischen Hochschule Darmstadt (IRT) in Darmstadt on April 24, 1978. The lectures are an account of work performed at IRT on the mechanics of fuel pins and fuel elements and supported by the Fast Breeder Project (PSB) of KfK. These activities can be broken down into studies of the integral fuel pin (URANUS computer code) and into multidimensional studies of the fuel pin using the finite-element method (FINEL and ZIDRIG computer codes). Moreover, a report is presented of the status of the test facility for simulation of out-of-pile cladding tube loads and of the IRT project on the simulation and analysis of radiation damage.

Full Text Available Der vorliegende Sammelband enthält Beiträge zu drei Schwerpunkten: Es geht erstens um hochschulweite Konzepte der Personal- und Organisationsentwicklung, gemessen an dem Prüfstein Gender Mainstreaming, zweitens um Ergebnisse der Lehr- und Lernforschung unter gendersensibler Perspektive und drittens um Genderaspekte und Genderkompetenz im Lehr- und Lernalltag. Die Einzelergebnisse bieten eine gute Orientierung; auf der theoretischen und konzeptionellen Ebene der Geschlechterforschung und der Geschlechterpolitik in der Hochschule ist jedoch kritisch anzumerken, dass unterschiedlichen Traditionen folgende Genderbegriffe und politische Strategien unvermittelt zusammengestellt werden, ohne deren Genealogien und politischen Kontexte zu reflektieren. Dies trifft besonders auf das Konzept des Gender Diversity Managements zu. Nicht einbezogen wird außerdem der internationale Forschungsstand zu den neuen Steuerungsformen in Hochschule und Wissenschaft insbesondere im Hinblick auf Prozesse des doing gender.This anthology contains articles about three main topics: first, university-wide concepts for human resource and organizational development regarding the touchstone gender mainstreaming; second, findings of teaching and learning research from a gender-sensitive perspective; and third, gender aspects and gender competence in the everyday life of teaching and learning. The individual findings offer a good orientation; however, regarding the theoretical and conceptual level of gender research and gender politics at the universities, it has to be noted critically that gender concepts and political strategies from varying traditions are put together abruptly without reflecting on their genealogies and political contexts. This is particularly true for the concept of gender diversity management. Furthermore, the international state of research regarding new forms of regulation in university and science, particularly considering processes of doing gender, is

Full Text Available Veranstaltungen zur Informationskompetenz sind ein fester Bestandteil an wissenschaftlichen Bibliotheken und spielen eine wichtige Rolle für eine erfolgreiche Hochschulausbildung. Durch die Neugründung der staatlichen Hochschule Hamm-Lippstadt konnten in den dortigen Bibliotheken Informationskompetenz-Veranstaltungen grundlegend neu konzipiert und umgesetzt werden. Bei der Neugestaltung mussten unterschiedliche Kriterien zu Inhalten, Formaten, Zielgruppen etc. berücksichtigt werden. Hierbei spielten auch Überlegungen eine Rolle, wie Informationskompetenz an der HSHL definiert werden soll. Im vorliegenden Artikel werden die zu berücksichtigenden Kriterien für die Umsetzung von Informationskompetenz-Veranstaltungen an der HSHL erläutert. Des Weiteren wird ein Ausblick gewagt, wie diese Veranstaltungen weiter ausgebaut werden können. Lectures on information literacy are an important part of the work of a scientific library and are crucial for a successful university education. The founding of the state University of Applied Sciences Hamm-Lippstadt created the opportunity to develop a completely new series of information literacy lectures. During the creation of this lecture series, different criteria such as content, format, target groups and others had to be considered. It was also a part of this process to specify how the term information literacy should be defined for the University of Applied Sciences Hamm Lippstadt. This article discusses the criteria applied to the implementation and also gives an outlook on possible further developments.

In seiner 2007 erschienen Sammlung von Vorträgen und Essays beschäftigt sich Wolfgang Frühwald, mit der Frage "Wieviel Wissen brauchen wir?“ [1] Die Kernproblematik moderner Wissenschaft und Forschung sieht der Autor, emeritierter Ordinarius für Neuere Deutsche Literaturwissenschaft und von 1992 bis 1997 Präsident der Deutschen Forschungsgemeinschaft, einerseits in der zunehmenden Spezialisierung der Wissenschaftsbereiche, andererseits in der Gefahr der Abkoppelung der Naturwissenschaften von den Geisteswissenschaften. Wiederholt plädiert er dafür, über der rasanten Entwicklung beispielsweise in der Biologie und Physik, die historische, gesellschaftliche und besonders die ethische Dimension der Forschung nicht zu übersehen und fordert eine übergeordnete Theorie der Wissenschaft, die nur im Dialog zwischen den einzelnen Fachgebieten zu entwickeln sei.

Uterine leiomyomas are the most common benign tumors of the female urogenital tract. Beside the classic surgical treatment options the minimal-invasive embolization therapy of the leiomyomas increasingly gains importance world-wide. Technique, complications, and results of uterine leiomyoma embolization will be presented. After careful evaluation of indications for embolization the procedure is mostly performed under conscious sedation. A single-sided femoral access route together with cross-over technique generally allows for a flow-directed embolization via both uterine arteries. After embolizing the vessels supplying the tumor, the uterine arteries should be still patent. The success rate of embolization of uterine leiomyomas ranges between 85 and 100%, whereas a reduction in size of the tumors in 42 to 83% and a relief of symptoms in up to 96% can be achieved. The total complication rate is about 10% with mainly ''minor complications''. Worldwide only three deaths following embolization of uterine leiomyomas were reported. The high technical and clinical success rate together with a low complication rate make the embolization of uterine leiomyomas a minimally-invasive alternative to the classic treatment. As long term results are not available indication to embolization of uterine leiomyomas must be carefully established in consensus with gynecologists. (orig.) [German] Uterusmyome sind die haeufigsten benignen Tumoren des weiblichen Genitaltrakts. Neben den klassischen operativ-gynaekologischen Behandlungsverfahren gewinnt die minimal-invasive Uterusmyomembolisation (UME) weltweit an Bedeutung.

Die Intervention kann meist unter Analgosedierung vorgenommen werden. Die Embolisation kann in der Regel ueber einen einseitigen femoralen Zugang erfolgen. In beide Aa. uterinae wird das Embolisat

Determining the status quo of existing biofuel plants in Germany, an extensive database of process configurations was received. This information was used to develop simulation models of virtual biofuel plants, which are now available for further investigations. The GHG emissions of biofuels can partly be improved by the studied optimization approaches. The studied optimization approaches can hence contribute to the increasing requirements for GHG reductions of biofuels. The integration of multiple optimization approaches in one concept would improve its GHG balance further. In addition to the investigated technical measures, emissions could also be reduced by adapting the energy supply. The use of biofuels for heat generation, for example, could have an additional reducing effect on total GHG emissions, because a fossil fuel-based heat and electricity supply is the main driver of the GHG balance. From the communication with contacts in the industry it can be said that the German biofuel industry operates production plants that have already reached a high level of efficiency. At many locations, additional measures and modifications are planned, not only driven by economic reasons but also to further improve the GHG balance. The overall results of the project will be published as DBFZ Report No. 22 ''Die Biokraftstoffproduktion in Deutschland - Stand der Technik und Optimierungsansaetze'' in 2015.

The introduction of the bolter miner technic at Auguste Victoria/Blumenthal mine will be shown. This benchmarking project coming from the australian mining industry was put into practice for the first time in the german hard coal industry. It was rapidly turned out, that the demands of the roadways concerning the number and length of the required bolts and as well as the safety aspects are very different to the visited headings in Australia. The way starting with an average drivage rate of 5 m/d day in the first project up to today's performance level of 16 m/d in the third project is represented. From a view on the totality it is described, what kind of demands are required by the logistics, the infrastructure, the organization of the operation, the ergonomics and last but not least the motivation of the crew to achieve a high performance of 22 m/d. (orig.) [German] Im Beitrag wird die Einfuehrung der Bolter-Miner-Technik auf dem Bergwerk Auguste Victoria/Blumenthal aufgezeigt. Dieses Benchmarking-Projekt aus dem australischen Bergbau wurde erstmalig im deutschen Steinkohlenbergbau umgesetzt. Es zeigte sich sehr schnell, dass die Anforderungen der Strecken in bezug auf die Anzahl und Laenge der einzubauenden Anker sowie die sicherheitlichen Aspekte zu den besuchten Vortrieben in Australien stark differierten. Zudem wird der Weg von durchschnittlich 5 m/d im ersten Projekt bis zu den heutigen Leistungsdaten von 16 m/d im dritten Projekt dargestellt. In einer ganzheitlichen Betrachtung wird aufgezeigt, welche Anforderungen in der Logistik, in der Infrastruktur, in der Betriebsorganisation, in der Ergonomie und in der Motivation der Mannschaft notwendig waren, Spitzenleistungen von 22 m/d zu erreichen.

Full Text Available Weltweit hat in den letzten 10 Jahren die Zahl der Knieendoprothesen-Implantationen stark zugenommen. Nach relativ kurzer Zeit wird durch die Operation eine erhebliche Verbesserung bezogen auf Schmerzbelastung, Gelenksfunktion und Lebensqualität erzielt. Minimal-invasive Zugänge in Kombination mit dazu neu entwickelten Instrumenten beeinträchtigen die Muskelfunktion weniger als der mediale parapatellare Standardzugang und verkürzen die frühe Rehabilitationsphase. Der Einsatz der Navigation erleichtert die präzise Positionierung der Implantate. Sowohl für die minimal-invasive Implantationstechnik als auch für die navigationsunterstützte Technik fehlen noch Ergebnisse, die gegenüber konventioneller Technik bessere Funktion und längere Standzeit dokumentieren. Moderne Prothesen ermöglichen eine Rotation des Unterschenkels entweder durch asymmetrische Formgebung der Femurkondylen oder durch die Rotation der Polyethylenplattform auf der Tibiakomponente bei Prothesen mit konformer Kondylengestaltung. Femur- und Tibiakomponenten mit rotierender Plattform sind aus CoCr-Stahl, Tibiakomponenten mit fest montiertem Polyethylenteil sind meist aus Titanlegierungen gefertigt. In den letzten Jahren werden bei Patienten mit bekannter Metallallergie (insbesondere Nickelallergie spezielle Implantate aus oberflächenbeschichtetem Titan oder Zirkonium eingesetzt. Cross-linked Polyethylen hat noch nicht die gleiche Verbreitung gefunden wie bei Hüftimplantaten. Prothesen mit erhöhter Flexionsmöglichkeit gewannen in letzter Zeit an Bedeutung. Der Einsatz von Halbschlitten-Prothesen ist durch minimal-invasive Zugänge und verbesserte Instrumente wieder populärer geworden. Die Vielfalt modularer Endoprothesensysteme verschiedener Hersteller hat insbesondere Revisionsoperationen leichter gemacht. Dadurch sind auch nach Wechseloperationen ähnliche Ergebnisse zu erzielen wie nach primärer Implantation.

We report on 230 phlebographic examinations in the shoulder arm region which were performed by conventional X-ray technique and/or digital subtraction angiography (DSA). The detailed method of examination as well as anatomical variants of the vessels are explained. The group of patients was analysed concerning its composition and was subdivided with regard to clinically relevant diagnoses. Contrary to statements in the literature, the number of pathological findings in men or women were equal. The main age was between 40 and 50 years. The brachial vein was found to be doubled so often that this might be accepted as a normal situation. Phlebographic examinations were performed in the right arm twice as often as in the left one. 172 primary examinations, more than 60% showed a pathological result. (orig.) [Deutsch] Es wird ueber 230 Phlebographien der Schulter-/Armregion berichtet, die bei 172 Patienten in konventioneller und/oder digitaler Technik (DSA) durchgefuehrt wurden.

Das Patientenkollektiv wurde sowohl hinsichtlich seiner Zusammensetzung analysiert als auch nach klinisch relevanten Diagnosegruppen hin aufgearbeitet. Entgegen den Literaturangaben waren Patienten mit pathologischen Armphlebographien gleichhaeufig maennlich oder weiblich. Der Altersgipfel lag zwischen 40 und 50 Jahren. Die V. brachialis war so haeufig doppelt angelegt, dass dieser Befund als Normsituation angesehen werden kann. Phlebographien wurden doppelt so oft am rechten als am linken Arm durchgefuehrt.

In August 1993 the first German `Delphi Report on Developments in Science and Technology` was published. It was elaborated by the Fraunhofer Institute for System Engineering and Innovation Research (FhG-ISI) in cooperation with the Japanese National Institute of Science and Technology Policy (NISTEP). The `MINI-DELPHI` now completed by FhG-ISI, again in cooperation with NISTEP, is a further development of the Delphi approach in that it is more differentiated in its questions and assessment criteria than its predecessors. `MINI-DELPHI` is not intended as a comprehensive forecast on technology in general but rather focusses on key topics. Its emphasis is on technology demand and the relevance of technologies to social issues. Although the Mini-Delphi study was primarily aimed at further refining the methodology employed, it nevertheless contains a wealth of information and details on circumscript questions. The requisite database is provided by tables on the results of two inquiry rounds among Japanese and German experts. (orig./RHM) [Deutsch] Im August 1993 wurde der erste deutsche `Delphi-Bericht zur Entwicklung von Wissenschaft und Technik` veroeffentlicht.

Mit dem jetzt vorliegenden `MINI-DELPHI` hat das FhG-ISI - wieder in Zusammenarbeit mit dem NISTEP - den Delphi-Ansatz fortentwickelt und sowohl hinsichtlich der Fragen als auch der Beurteilungskriterien weiter ausdifferenziert. `MINI-DELPHI` bezweckt keine umfassende Technologievorausschau, sondern konzentriert sich auf Schluesselthemen. Im Vordergrund steht der Gedanke des Technikbedarfs und die Relevanz fuer gesellschaftliche Fragestellungen. Obwohl die Mini-Delphi-Studie vorrangig der Weiterentwicklung der Methodik dient, enthaelt sich eine Fuelle von Informationen und Details zu Einzelfragen. Die im Bericht

Die Biopsie erfolgte als Oktantenbiopsie nach den derzeit gültigen Schemata, radikal prostatektomiert wurde in auschließlich retropubischer aszendierender Form. Ergebnisse: Die Untersuchung der histologischen Ergebnisse zeigte in einem überraschend hohen Prozentsatz (58 % einen Karzinombefund in beiden Prostataseitenlappen (pT2c, in 12 % eine Organüberschreitung. Es fand sich in lediglich 18 % der Fälle ein kleines Karzinom in einem Seitenlappen (pT2a. Schlußfolgerung: Bei auch nur einer positiven Stanzbiopsie kann keine Vorhersage für das histologische Stadium nach Radikaloperation und damit den wahrscheinlichen klinischen Verlauf getroffen werden.

Zwischen November 2014 und Juni 2015 wurden 21 Patienten mit 25 Hirnmetastasen mit SRS in FFF-Technik behandelt. Die Hirnmetastasen wurden mit 1 x 20 Gy oder 1 x 18 Gy auf die konformal umschliessende 80 %-Isodose bestrahlt. Drei Patienten mit kritisch lokalisierten oder grossen Metastasen (>3 cm) erhielten eine Bestrahlung mit 6 x 5 Gy. Konformitaet, Dosisgradienten, Behandlungszeiten, Normalgewebsdosis (Gehirn) sowie Anzahl an Monitoreinheiten wurden zur Evaluation der Planqualitaet herangezogen. Des Weiteren wurden Ueberleben und Toxizitaet analysiert. Sowohl die Bestrahlungszeit sank signifikant um 57,9 % (p ≤ 0,001) fuer die SRS in FFF-Technik im Vergleich zur FF-Technik. als auch die durchschnittliche Bestrahlungsdosis des Gehirns (p = 0,001). Des Weiteren wurden signifikant verbesserte Dosisgradienten und folglich ein steilerer Dosisabfall fuer die SRS in FFF-Technik (-1,1 %, -29,6 %; p ≤ 0,003) festgestellt. Dagegen zeigte die SRS in FF-Technik einen leicht verbesserten Konformitaetsindex (-1,3 %; p = 0,001). Bei einer medianen Nachbeobachtungzeit von 5,1 Monaten betrug das 6-Monats-Gesamtueberleben 63,3 %. Bei den behandelten 25 Hirnmetastasen (96 %) waren 24 ohne lokalen Progress. SRS in FFF-Technik ist zeiteffizient und ermoeglicht gleiche Planqualitaet sowie eine leicht reduzierte Dosisbelastung des gesunden Hirngewebes im Vergleich zur SRS in FF-Technik. Entsprechend vielversprechend sind die ersten klinischen Ergebnisse bei moderater Toxizitaet. (orig.)

2003-01-01

Full Text Available Zweck dieser Untersuchung war es, die Effizienz von Transitionalzonenbiopsien und von Biopsien der lateralen Anteile der Prostata zur Karzinomentdeckung zu untersuchen, nachdem eine vorangegangene Biopsie keinen Tumor finden konnte. Methodik: Wir untersuchten 74 Präparate nach radikaler Prostatektomie und unterzogen diese einer sonographisch gezielten Prostatabiopsie ex vivo. Zuerst erfolgte eine Sextantenbiopsie, dann zwei unterschiedliche Rebiopsien. Rebiopsie-Technik A bestand aus einer lateral plazierten Sextantenbiopsie und zwei Stanzen aus den Transitionalzonen je Seite. Rebiopsie-Technik B bestand aus einer Sextantenbiopsie und zwei Stanzen je Seite aus den lateralen Arealen der Prostata. Ergebnisse: Mit der initialen Sextantenbiopsie konnten 39 Karzinome gefunden werden (53 %. Von den verbliebenen Karzinomen konnten mit der Rebiopsie-Technik A 12 Karzinome gefunden werden. In dieser Gruppe fand eine lateral durchgeführte Sextantenbiopsie 12 Karzinome. Die Transitionalzonenbiopsien waren in 5 Fällen positiv, jedoch konnte kein zusätzlicher Tumor entdeckt werden. Mit der Rebiopsie-Technik B wurden 23 Karzinome gefunden. 14 Tumore enthielten die Stanzen der Sextantenbiopsie. Zusätzliche 9 Tumore waren in den Stanzen aus den lateralen Arealen der Prostata enthalten. Schlußfolgerungen: Eine Standard-Sextantenbiopsie hat eine niedrige Sensitivität von nur 53 %. Eine Biopsie, welche die Transitionalzonen inkludiert, ist nicht geeignet, die verbliebenen Karzinome zu finden. In dieser Studie zeigte die Wiederholung einer Sextantenbiopsie mit zusätzlichen Stanzen aus den lateralen Arealen das beste Ergebnis bei der Rebiopsie.

a Precise, Low-Cost Rtk Gnss System for Uav Applications

Science.gov (United States)

Stempfhuber, W.; Buchholz, M.

2011-09-01

High accuracy with real-time positioning of moving objects has been considered a standard task of engineering geodesy for 10 to 15 years. An absolute positioning accuracy of 1-3 cm is generally possible worldwide and is further used in many areas of machine guidance (machine control and guidance), and farming (precision farming) as well as for various special applications (e.g. railway trolley, mining, etc.). The cost of the measuring instruments required for the use of geodetic L1/L2 receivers with a local reference station amounts to approximately USD 30,000 to 50,000. Therefore, dual frequency RTK GNSS receivers are not used in the mass market. Affordable GPS/GNSS modules have already reached the mass market in various areas such as mobile phones, car navigation, the leisure industry, etc. Kinematic real-time positioning applications with centimetre or decimetre levels could also evolve into a mass product. In order for this to happen, the costs for such systems must lie between USD 1,000 to 2,000. What exactly low-cost means is determined by the precise specifications of the given individual application. Several university studies in geodesy focus on the approach of high-accuracy positioning by means of single frequency receivers for static applications [e.g. GLABSCH et. al. 2009, SCHWIEGER and GLÄSER 2005, ALKAN 2010, REALINI et. al. 2010, KORTH and HOFMANN 2011]. Although intelligent approaches have been developed that compute a trajectory in the post-processing mode [REALINI et. al., 2010], at present, there are only a very few GNSS Low-Cost Systems that enable real-time processing. This approach to precise position determination by means of the computation of static raw data with single frequency receivers is currently being explored in a research project at the Beuth Hochschule für Technik Berlin - and is being further developed for kinematic applications. The project is embedded in the European Social Fund. It is a follow-up project in the area of

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.)

Irreversible Komplikationen werden bei Einhalten der korrekten Technik und Verwendung duenner 21- oder 22-gg.-Nadeln nur sporadisch beschrieben. Wir beobachten bei 20 durchgefuehrten lumbalen Sympathikolysen 7 klinische Verbesserungen und 13 Amputationen. Die Literaturergebnisse der Methode schwanken demgegenueber bei der lumbalen Sympathikolyse von 39-89% klinischer Erfolgsrate, bei der thorakalen Sympathikolyse von 70-100% und bei der Zoeeliakusblockade von 0-100%. Die Hypothese, eine Extremitaetenerwaermung nach Sympathikolyse sei nur durch Stealeffekte zugunsten der Hautdurchblutung bedingt, konnte durch Flussmessungen widerlegt werden. Waehrend bei der lumbalen Sympathikolyse vor allem die Vorselektion des Patientenguts die unterschiedlichen Erfolgsraten erklaert, spielen bei den anderen Verfahren vor allem die Indikationsstellungen eine herausragende Rolle. Patienten mit palmarer Hyperhidrose profitieren mehr von der perkutanen Neurolyse als Patienten mit Raynaudsymptomatik, Patienten mit Pankreaskarzinom mehr als solche mit Pankreatitis. (orig./VHE)

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.

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.

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

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

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.

Clustering of galaxies with f(R) gravity

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

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

Solar System constraints to general f(R) gravity

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

International Nuclear Information System (INIS)

Brax, Philippe; Bruck, Carsten van de; Davis, Anne-Christine; Shaw, Douglas J.

2008-01-01

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

International Nuclear Information System (INIS)

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.

Recent Recommendations of the TWG-FR & implementation: ⇨ Increase the efforts to make more countries participating in its activities → Sweden became full member of TWG-FR this year. ⇨ Concentrate all research and technical activities related to FR under the TWG-FR umbrella. An efficient and effective interface between INPRO and TWG-FR should be established to avoid duplication/overlapping of activities → done. ⇨ Closer cooperation links should be established with FR-related activities implemented within the framework of other international programmes (e.g. GIF, INPRO, OECD/NEA, ESNII) → systematic collaboration with INPRO, interface with GIF, participation to NEA-TF on SFR, member of External Advisory Committee of some Euratom projects. ⇨ Continue to secure training and education in the field of Fast Neutron System Physics, Technology and Applications, and respective Schools/Seminars should be held on a regular basis → 4 events: 2 in 2011 and 2 in 2012 (Trieste, Bariloche). ⇨ Launch new CRPs in the field of safety of FR with special emphasis on severe accidents → launch of EBR-II CRP + 4 related Workshops/TMs. ⇨ The IAEA, with technical inputs from the TWG-FR, should produce international safety standards relevant to fast reactors → Initiated discussion with Department of Nuclear Safety and Security + INPRO/GIF for SFR Safety Design Criteria

Effective Dark Matter Halo Catalog in f(R) Gravity.

He, Jian-Hua; Hawken, Adam J; Li, Baojiu; Guzzo, Luigi

2015-08-14

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.

基于FrFT-MUSIC的空时频算法%Space-time-frequency Algorithm Based on FrFT-MUSIC

2011-01-01

针对传统时频分析方法难以对星载分布式合成孔径雷达(SAR)系统中地面目标速度进行准确估计的问题,提出了分数阶傅里叶变换(FrFT)-多重信号分类(MUSIC)空时频方法.利用FrFT获得信号向量并构造空时频分布矩阵；应用该分布矩阵替代传统MUSIC算法中的协方差矩阵,从而求得FrFT- MUSIC空时频谱,通过对谱函数进行搜索估计目标速度.仿真实验表明,该方法的目标速度估计精度高,抗噪声能力强.%The fractional Fourier transform (FrFT)-multipIe signal classification (MUSIC) space-time-frequency algorithm is proposed to solve the problem that it is difficult for the traditional time-frequency analysis method to accurately estimate the ground targets' azimuth speed which is coupled with spaceborne distributed synthetic aperture radar" (SAR). 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.

Hulne, S.

1988-01-01

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.

Hippocampus sparing in whole-brain radiotherapy. A review

Radiation treatment techniques for whole-brain radiation therapy (WBRT) have not changed significantly since development of the procedure. However, the recent development of novel techniques such as intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT) and helical tomotherapy, as well as an increasing body of evidence concerning neural stem cells (NSCs) have altered the conventional WBRT treatment paradigm. In this regard, hippocampus-sparing WBRT is a novel technique that aims to spare critical hippocampus regions without compromising tumour control. Published data on this new technique are limited to planning and feasibility studies; data on patient outcome are still lacking. However, several prospective trials to analyse the feasibility of this technique and to document clinical outcome in terms of reduced neurotoxicity are ongoing. (orig.) [German] Die Technik der Ganzhirnbestrahlung (''whole-brain radiation therapy'', WBRT) hat sich seit der Entwicklung nicht wesentlich veraendert. Allerdings stellten die Neuentwicklung von Techniken wie die intensitaetsmodulierte Strahlentherapie (IMRT), die volumenmodulierte Arc-Therapie (VMAT) oder die helikale Tomotherapie sowie immer groesseres Wissen ueber das neurale Stammzellkompartiment (NSCs) das herkoemmliche Ganzhirn-Paradigma in Frage. Die hippocampusschonende Ganzhirnbestrahlung ist eine neuartige Technik, welche die kritische Region des Hippocampus schont, ohne die Tumorkontrolle zu gefaehrden. Ueber diese Technik gibt es bisher nur eine begrenzte Datenlage im Sinne von Planungs- und Machbarkeitsstudien. Klinische Daten bzgl. der Behandlungsergebnisse fehlen nach wie vor, aber einige prospektive Studien sind im Gange, um nicht nur die Machbarkeit zu belegen, sondern auch das klinische Outcome im Sinne einer verringerten Neurotoxizitaet nachzuweisen.

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.

Agency doctorates

International Nuclear Information System (INIS)

1970-01-01

Staff members of the Agency working at the Seibersdorf laboratory are continuing to achieve high academic distinction. Two more - both Austrian - have now been awarded the degree of Doctor of Agriculture. Joachim Kramer, who is 26, graduated from the Hochschule fur Bodenkultur in 1967 with the degree of Diplom-Ingenieur and then started work in the plant breeding and genetics section of the laboratory under the direction of Dr. Knut Mikaelsen. The results of the research work he carried out were accepted as the subject of a thesis for which he has now been granted his doctorate. The doctoral promotion took place on 30 June, at a ceremony attended by Dr. Andre Finkelstein, Deputy Director General for Research and Isotopes. The subject of Dr. Kramer's thesis was a comprehensive study of the mutagenic effects of fast neutrons and gamma rays, and the influence of various modifying factors such as water content, oxygen and metabolic state of seeds at the time of irradiation. This work has contributed significantly to the understanding of the mechanisms by which these two types of ionizing radiation produce mutations in seeds. The knowledge gained will be of great importance in the efficient use of ionizing radiation in practical plant breeding. Paul Wassermann, who is 33 years old, joined the Agency in 1965. He, too, graduated from the Hochschule fur Bodenkultur as Diplom-Ingenieur in agriculture, having graduated with honours previously from the agricultural secondary school at Raumberg, Austria, in 1958. Dr. Wassermann's own words may be used to explain how he came to gain his doctorate. 'In October, 1966, I completed my studies at the Hochschule,' he writes. 'I was employed at the Agency laboratories in Seibersdorf, working in the plant and soils group. Encouraged by the interesting research which was performed there, a thesis entitled 'the Fate of Nitrogen in Submerged Rice Soils' was started, which finally led to the doctor's degree in Agriculture in June this year

The models of f(R) gravity belong to an important class of modified gravity models where the late time cosmic accelerated expansion is considered as the manifestation of the large scale modification of the force of gravity. f(R) gravity models can be expressed in terms of a scalar degree of freedom by explicit redefinition of model's variable. Here we report about the study of the features of cosmological parameters and hence the cosmological evolution using the scalar degree of freedom of the f(R) = ξR n gravity model in the Friedmann-Lemaître-Robertson-Walker (FLRW) background

Die Injektion von Knochenzement zur Stabilisierung von Wirbelfrakturen ist effizient und hat sich bewährt. Damit erreicht man eine Stabilisierung des Wirbels und eine sehr wirksame Schmerzkontrolle. Zusätzlich (und häufig zu wenig beachtet können damit ein weiteres Einsintern des Knochens verhindert und Folgekomplikationen so vermieden werden. Wo diese einfache minimalinvasive Technik nicht mehr genügt, sind offene Verfahren notwendig. Auch dabei wird eine kombinierte Technik angewendet: Die Stabilisierung erfolgt nach den gängigen wirbelsäulenchirurgischen Prinzipien, zur Verankerung der Implantate im osteoporotischen Knochen wird ebenfalls Knochenzement verwendet.

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...

The entire planning of offshore wind farms is based on a reliable preliminary exploration of the sea bed. Thus, researchers have developed a new method with which the sea bed can be inspected much more accurate than before. For this, the Fraunhofer Institute for Wind Energy and Energy System Technology (Bremerhaven, Federal Republic of Germany) has developed a preliminary exploration procedure that examines the sedimentary structure by means of sound waves. Compared to conventional methods, this preliminary exploration procedure has two advantages: (1) A special air pressure pulser (airgun) is used as a special air pressure pulse. The airgun produces air bubbles that are pumped into the water exercising pressure and thus producing an acoustic signal; (2) The reflected acoustic signals are recorded not only by a single detector, but also by 60 hydrophones that are pulled at a tube behind the boat.

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

Jaime, Luisa G.; Patino, Leonardo; Salgado, Marcelo

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.

F(R Gravity’s Rainbow and Its Einstein Counterpart

S. H. Hendi

2016-01-01

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.

We show how the bounce solutions in this theory are modified due to nonlinear effect of f(R) gravity. In addition we find that the solutions exist when the Universe can make turn around for large scale-factor. Therefore, in principle, the Universe in this set-up can show cyclic behavior. (orig.)

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

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.)

Es wurde keine weitere Assoziation zwischen Hodenkrebs und anderen Berufen beobachtet.Fazit: Ein erhöhtes Risiko für Hodenkrebs wurde für Techniker und verwandte Berufe sowie für Bürokräfte beobachtet. Dies könnte auf den sozioökonomischen Status bzw. die bewegungsarme Lebensweise zurückgeführt werden, was auch schon in früheren Studien gezeigt wurde. Während die Machbarkeit einer rein Register-basierten Studie gezeigt wurde, stellen die fehlenden beruflichen Daten sowie die Wahl der Krebskontrollen eine Herausforderung für die Richtigkeit dieses Ansatzes dar.

Effective Geothermal Utilisation close to the surface by the TT-Geothermal Radial Drilling (GRD-Method

Directory of Open Access Journals (Sweden)

Hans-Joachim Bayer

2007-01-01

Full Text Available In the late 1970-Years, Tracto-Technik developped a very effective radial-shaped percussion system for a geothermal heating, the ECOtherm-System, which was very well accepted by customers. Nowadays, a radial-shaped drilling system, operating some decameters below the surface, was developped by Tracto-Technik, which offers the chance of a very effective drilling for the use of geothermal energy. The main advantage of this development is the reduction of drilling costs by new constructions and new handling possibilities. Drilling processes like the rod connecting or the drill-hole enlargement were solved in other ways as usual, by very time-shortening and effective ways, which are presented in the paper. The new TT-Geothermal radial drilling methods need only a very small but highly effective drilling unit, which reduces the operational drilling cost in a enormous way. All operational drilling steps are reduced to less than a half time as usual. By these GRD-methods, the use of surface-close geothermal energy is simplified and less expansive.

2002-07-01

This report is intended to explain the outline of the research and development (R and D) in the FY 2001 on cost-benefit analysis of FR (Fast Reactor) cycle system concepts. 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

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.

Propagating Degrees of Freedom in f(R Gravity

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.

We can see at every turn how instruments once used for the good of mankind become blunt right before our very eyes. They still serve their purpose, but each further step brings about less additional benefit ('residual benefit'). This is a fundamental problem rather than a detail problem, as it is the self-concept, reliability and stability of our public order that is at risk. 'Constitution' in this sense is more than just the legal basis of the state; as used by the author it refers to the laws governing a society's life. (orig./HSCH).

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

Zhang, Xiangdong; Ma, Yongge

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.

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)

2016-06-15

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.

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.

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

Energy Technology Data Exchange (ETDEWEB)

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

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

Leistung und Wettbewerb – Die Entwicklung des schwedischen Hochschul- und Forschungssystems seit 1945

Directory of Open Access Journals (Sweden)

Lars Engwall

2006-01-01

Full Text Available This paper analyzes the Swedish system of higher education and research with respect to the allocation of research resources. The main findings are a considerable expansion of the system since the post war era as well as a strong trend towards decentralization during the last decades. The earlier visible hand of close governance has left power to an invisible hand of market governance. Also, methods of New Public Management have been introduced. Despite an increasing tendency for research evaluations in Sweden the link to funding has so far been weak, however. Even if resources for research to an increasing extent are allocated through short-term project grants rather than long-term block grants a clear tendency towards funding of fewer and larger programmes rather than many small projects can be observed.

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

1982-01-01

This paper intends to counter with a demand for systematics the boom of ecological oriented criticism passed on technical science and engineering and on the fact that individual sciences make a subject of engineering. It deals with the theoretical foundations of relationships between technology, society and nature. An interdisciplinary approach attempts to do justice to the multi-dimensionality of engineering and ''technology''. This approach includes the formulation of questions and the findings of social sciences, philosophy, and technology. The object is to determine technology as a form of social practice - a practice which includes the vital adjustment of man to his natural environment as well as the organisation of his social behaviour.

The presented case study by the Fraunhofer Institute ISE shows that the market for stationary electrochemical storage prices are currently too high for economical operation. In winter, a battery in Germany is not always fully loaded because of low sunlight. Therefore, the combination of a battery with a PV system at this time of year does not have enough full cycles to be economical. For more complete cycles of the year and consequently lower specific storage cost wind turbines or other power generators can be connected. Since - in contrast to lead acid batteries - there is no experience with long-term storage in lithium and redox flow batteries, this study is based on current forecasts. Compared to lithium-ion batteries, lead-acid and redox flow batteries have a lower efficiency, so that the investment costs of the battery must be lower because fewer savings can be achieved. Especially for short-term storage, the production costs must be reduced. The cost reduction potential of redox flow and lithium-ion batteries is due to the current technical state of development compared to lead acid batteries very high. This means that an economic operation in the future is possible with constant development of electricity and battery prices. [German] Die vorgestellte Fallstudie des Fraunhofer Instituts ISE zeigt, dass die Marktpreise fuer stationaere elektrochemische Speicher aktuell fuer einen wirtschaftlichen Betrieb zu hoch sind. Im Winter wird eine Batterie in Deutschland aufgrund der niedrigen Sonneneinstrahlung nicht immer komplett geladen. Daher hat die Kombination eines Speichers mit einer PV-Anlage zu dieser Jahreszeit nicht genug Vollzyklen, um wirtschaftlich zu sein. Fuer mehr Vollzyklen im Jahr und demzufolge geringere spezifische Speicherkosten koennen Windkraftanlagen oder andere Stromerzeuger angeschlossen werden. Da es- im Gegensatz zu Bleisaeure- Batterien - noch keine Erfahrung mit Langzeitspeichern im Bereich Lithium und Redox-Flow gibt, beruht diese Studie auf heutigen Prognosen. Im Vergleich zu Lithium-Ionen-Batterien haben Bleisaeure- und Redox-Flow-Batterien einen geringeren Wirkungsgrad, so dass die Investitionskosten des Speichers geringer sein muessen, da weniger Einsparungen erzielt werden koennen. Vor allem fuer Kurzzeitspeicher muessen die Herstellungskosten gesenkt werden. Das Kostenreduktionspotenzial von Redox-Flow- und Lithium-Ionen-Batterien ist aufgrund des aktuellen technischen Entwicklungsstands verglichen mit Bleisaeure-Batterien sehr hoch. Dies bedeutet, dass bei bleibender Entwicklung der Strom- und Batteriepreise ein wirtschaftlicher Betrieb in Zukunft moeglich ist.

The present situation of primary energy in the WOCC-countries (world outside communist countries) and especially in the Federal Republic of Germany gives cause to anticipate that coal, in addition to nuclear energy, will gain increasingly more importance as a substitutional energy for petroleum and natural gas in medium-term, i.e. by the year 2000. Furthermore, coal will be the bridge between the present which is characterised mainly by fossil primary energies and the future which is likely to be based on nuclear energy, solar energy and hydrogen. The article deals with the question of whether coal is able to play this role of a substitutional and bridging energy. Is is shown that this seems to be possible as far as the natural resources and reserves and todays mining and transport technologies and the present situation of the world coal market are concerned. Thinking of the necessity of the enormous expansion of the world coal economy and the strong environmental pollution connected with it (bigger area needed, dust emmission, CO/sub 2/-problem) it seems doubtful if this is really desirable from the economical-ecological point-of-view and if it can be enforced politically.

A new fast MR-venography approach using a high resolution True-FISP imaging sequence was investigated in 20 patients suffering from 23 deep vein thromboses. Diagnosis was proven by X-ray venography, CT or ultrasound examination. The presented technique allowed for clear thrombus visualization with a high contrast to the surrounding blood pool even in calf veins. Acquisition time was less than 10 minutes for imaging the pelvis and the legs. No contrast media was needed. The presented high resolution True-FISP MR-veography is a promising non-invasive, fast MR-venography approach for detection of deep venous thrombosis. (orig.)

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.

Transobturatorielle Schlingensysteme (Monarc(R, Serasis TO(R: Ein erster Erfahrungsbericht von 150 Fällen

Directory of Open Access Journals (Sweden)

Fischer A

2005-01-01

Full Text Available Fragestellung: Überkorrektur mit ihren Begleiterscheinungen Obstruktion und Drangsymptomatik, retropubisches Hämatom und Blasenperforation sind die Hauptkomplikationen der mitturethralen spannungsfreien Bänder und kommen selbst nach fast 2000 Anwendungen immer wieder einmal vor. Zum Teil ist dies abhängig von Voroperationen, der Indikationsstellung, zum Teil auch von der Bandspannung, möglicherweise aber auch vom Weg des Bandes um die Urethra. Die Anwendung eines transobturatoriellen Systems soll nun zeigen, wo die Unterschiede bei dieser unterschiedlichen Technik und Bandverlauf liegen. Methode: 100 transobturatorielle Schlingen vom Typ Monarc(R (AMS, Berlin und 50 transobturatorielle Schlingen Serasis TO(R (Serag-Wiessner, Naila wurden in der Zeit von Anfang Februar bis Mitte Mai 2003 in unserer Klinik eingelegt. Perinealsonographie und Urodynamik inkl. Pad-Test sowie eine körperliche Untersuchung und ein Patientinnenfragebogen zur QoL wurden bei allen Frauen präoperativ und in der Folge nach 6 Wochen, 3 und 6 Monaten postoperativ durchgeführt. Ein Valsalva Leak Point Pressure wurde prä- und postoperativ nach 6 Monaten ermittelt. Der Eingriff erfolgt in Kurznarkose. Ergebnisse: Bei beiden Systemen zeigte sich eine durchschnittliche OP-Zeit von 8–10 Minuten und eine fehlende Hämatombildung sowie eine Blasenläsion bei der Monarc-Anwendung. Sonst trat bei beiden Systemen keine intraoperative Komplikation bei einem durchschnittlichen Blutverlust von ca. 20 ml auf. Perioperativ zeigte sich bei 12 % der mit Monarc behandelten Patienten eine Bakteriurie in den ersten 48 Stunden postoperativ, bei den Serasis-Patientinnen in 4 % der Fälle. Drei Monarc-Bänder und ein Serasis-Band mußten im Zusammenhang mit Drang durchtrennt werden. Fehlende postoperative Wundschmerzen und bis dato praktisch keine Zeichen einer Überkorrektur oder pathologischen Restharnbildung lassen den Unterschied zu den etablierten Inkontinenzoperationen deutlich

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

International Nuclear Information System (INIS)

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

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.)

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)

Full Text Available Unfavorable job market conditions and the related increase in pressure to legitimate the social sciences and humanities have drawn attention within these disciplines to approaches which have turned their own academic considerations into a starting point for practical concepts. In this sense, the following approach out of the field of applied discourse analysis attempts to develop application-oriented suggestions based on the analysis of authentic oral examinations at the university level. Beginning with an analysis of observable communicative behavior on behalf of oral examination participants, the following didactic suggestions aim to develop solid advice for instructors and students. Both the analysis and the practical suggestions aim to establish the scopes and limits concerning communication in institutionally organized exam situations. The aim of this approach is to support examination participants in recognizing and utilizing the given range of communicative possibilities.
