The issue of projecting policies ensuring appropriate energy supply in the future has become more important in Germany after conclusion of the agreement on a long-term nuclear power phase-out. A recent comparative analysis of a selection of scientific studies forecasting the implications of a nuclear power phase-out has shown that there is demand for more studies examining the issue in greater detail, and on the basis of an enlarged scope of research topics. Hence the present study, intended as a preliminary analysis, will investigate the potential, conditions of successful application, conceivable support schemes, and effects of those policy options that in any case, apart from the nuclear power phase-out scenario, are of essential importance in the context of building the proper conditions for sustainable development of Germany's energy sector. The options and strategies examined are: stepping up energy efficiency programmes and incentives, enhancing exploitation of the considerable potential of renewable energy sources, considering problems and benefits of enhanced use of fossil energy sources, primarily natural gas. (orig./CB) [German] Die Frage der zukuenftigen Ausgestaltung der Energieversorgung hat nach der Vereinbarung ueber den langfristigen Kernenergie-Ausstieg einen hoeheren Stellenwert erhalten. Nach Vorliegen einer vergleichenden Analyse ausgewaehlter wissenschaftlicher Studien zu den Auswirkungen eines Ausstiegs aus der Nutzung der Kernenergie in Deutschland wurde deutlich, dass vertiefende Untersuchungen noetig sind, und dass das Thema umfassender formuliert werden muss. Die vorliegende Analyse in der Form einer Vorstudie untersucht daher die Potenziale, Einsatzbedingungen, Foerdermoeglichleiten und Auswirkungen derjenigen strategischen Optionen, die auf jeden Fall, abgesehen von den Auswirkungen eines Ausstiegs aus der Kernenergie, von zentraler Bedeutung fuer eine langfristig nachhaltige Entwicklung im Energiesektor Deutschlands sein werden

With the translation of Agenda 21 all the documents released in connection with the United Nations Conference of Environment and Development (UNCED) at Rio de Janeiro (June 1992) have now been made generally available also in the German language. Agenda 21, which in 40 chapters discusses the basic political platforms of environment-oriented sustainable development, is an action programme for the 21st century adopted at Rio by more than 170 states. The action programme contains detailed instructions as to the practices to be abandoned to prevent any further deteriorations as well as strategies to be adopted to gradually relieve the situation and to ensure a reasonable and sustainable exploitation of our natural resources. One important approach to this goal is that environmental issues are considered within a global context, thus being a prominent factor in all political spheres. The rules set up in this action programme are applicable to industrial and developing countries alike. It offers - in broad outline - prescriptions for the combatting poverty, control of overpopulation, reconciliation of commercial and environmental interests, disposal of refuse and chemicals, for climate, energy and agricultural policies as well as the ways in which industrial and developing countries could cooperate both financially and in terms of shared technologies. The bilateral and multilateral development policies of the Federal Government are largely based on Agende 21. (orig./HP) [Deutsch] Mit der Uebersetzung der Agenda 21 sind nunmehr alle Dokumente der Konferenz fuer Umwelt und Entwicklung der Vereinten Nationen (UNCED) in Rio de Janeiro (June 1992) auch in deutscher Sprache der Oeffenlichkeit zugaenglich.

Bewegung bei Vorschulkindern: Empfehlungen und Wirklichkeit

Directory of Open Access Journals (Sweden)

Graf C

2011-01-01

Full Text Available Bewegung und körperliche Aktivität spielen insbesondere in der ganzheitlichen Entwicklung von Kindern eine wichtige Rolle. Heutzutage ist der kindliche Lebensstil allerdings von Bewegungsarmut und der Nutzung audiovisueller Medien geprägt. Bereits Kindergartenkinder sind überwiegend inaktiv bzw. verbringen viel Zeit mit Fernsehen. Eine mögliche Folge von mangelnder Bewegung können motorische Defizite darstellen. In eigenen Kollektiven schneiden mindestens 45 % der Kinder unterdurchschnittlich in den motorischen Hauptbeanspruchungsformen Koordination, Kraft und Schnelligkeit ab. Inwiefern sich dies langfristig auf die gesunde körperliche, aber auch geistige und emotionale Entwicklung der Kinder auswirkt, kann derzeit noch nicht beantwortet werden. Sicherlich unterstützen aber motorische Defizite ein Meidungsverhalten und den weiteren Rückzug aus der Bewegung sowie die Entwicklung von Übergewicht und Adipositas. Allgemein wird für Kinder in dieser Altersgruppe mindestens 2 Stunden tägliche Bewegungszeit sowie eine Reduktion der Fernsehzeit auf maximal 30 Min. empfohlen. Um diese Ziele zu erreichen bzw. zu unterstützen, sind effektive präventive Programme in den verschiedenen Lebensräumen der Kinder, Kindergärten, aber auch pädiatrischen Praxen etc. vonnöten. Bislang ist kein gesundheitsförderlicher/ präventiver „Königsweg“ bekannt, insbesondere nicht für Risikofamilien mit einem geringen sozioökonomischen Status und/oder Migrationshintergrund. Wichtig erscheinen aber die Förderung der intersektoralen Zusammenarbeit und ein Schwerpunkt in der Planung und Umsetzung auf Qualitätssicherung und Projektmanagement, um auch nachhaltig die Gesundheit der Kinder zu unterstützen.

The expansion of renewable energies is a central pillar of the energy transition. The development is positive: In 2016, renewable energies accounted for 31.7 percent of total gross electricity consumption. The brochure informs about the progress achieved in the further development of renewable energies in Germany, Europe and the world. The data on the development of renewable energies in Germany is based on the results of the Working Group on Renewable Energy Statistics (AGEE-Stat), which compiles the balance sheet of renewable energies for Germany on behalf of the BMWi. The data published here are a snapshot with the editorial deadline of August 2016 - they are still provisional in some places, especially for 2016. At the same time, current time series on the development of renewable energies in Germany since 1990 as well as a variety of graphs are published on the websites of the BMWi. These time series and graphs will be updated at the turn of the year 2017/2018. [German] Der Ausbau der erneuerbaren Energien ist eine zentrale Saeule der Energiewende.

The present technology assessment study examines the effects of three technology scenarios on future energy consumption and the energy-related emissions by industrial manufacturing in Switzerland. The three paths of development (Trend, High-Tech, Alternative) can be represented as follows: After a reduction until 2015, the Trend development entails a slight increase in consumption of energy. Until then consumption is some 10 percent lower in both the High-Tech and the Alternative Scenarios. Consumption of electricity increases in all scenarios, the proportion is highest in 20 year's time under the High-Tech scenario. SO{sub 2} and CO{sub 2} emissions decrease in all scenarios until 2000 and then level out at a low level. The emissions are lowest in the High-Tech scenario. In contrast the NO{sub x} and the VOC emissions diminish until 2000 and then rise again continuously. At this juncture important bases are still not yet available for a definitive evaluation with respect to the sustainable development. Sustainability objectives are currently being compiled for Switzerland in the wake of the Berlin Climate Conference and the Rio Conference. In the political lobbies the Green factions are making demands, such as those currently under discussion internationally (e.g. CO{sub 2} reductions on a scale of some 80 percent by 2050), whereas conservative and industrial circle representatives support the objective of sustainable development but reject a quantification of objectives. The official objectives of the Swiss Energy 2000 programme can be achieved with all scenarios. With the High-Tech and Alternative scenarios, concepts of a reduction in CO{sub 2} by 20 percent by 2015 (as currently under discussion in Switzerland), are realistic. However, further energy-relevant efficiency potentials in industrial production can be activated by energy-policy motivated measures. More extensive objectives, such as e.g. a CO{sub 2} reduction of 50 percent, are hardly attainable, even in the long-term, without sufficiency considerations in industrial production. The degree of acceptance of measures diminishes on the conservative and business sides with increasing interventionism whereas the Green lobby would put up with direct guidance measures and, above all, negative effects on the Swiss labour market.

The project CuRa: (German acronym for Cooperation for Environmentally Friendly Exchange of Resources) aimed to design elements to put into practice the model of sustainable development. The focus was on the participation of industry and business on a regional level and two model regions were chosen for the analysis of case studies. It was intended to give impulses for regional material flow networks between companies, for example by bundling similar material flows to achieve a better profitability and by one-to-one cooperation between companies, one of them using the waste of the partner as raw material. In addition, the potential for reducing material throughput using modern information technology was investigated in a case study. A set of theses derived from institutional theory was verified on the basis of the empirical results. Useful for the development and the stabilization of networks are, among others, expected economic benefits for the partners, common socio-cultural values and traditions, and using existing institutional arrangements as a basis. Different forms of market and policy failures were identified as obstacles, e.g. the established system of waste disposal services, the focus among the responsible actors on compliance with existing rules, and different regulatory obstacles. Nevertheless, in spite of the insufficient number of successful examples and demonstration projects, a shift in orientation from focusing on mere waste disposal towards a closed loop recycling economy and even towards sustainable development was identified within the commercial sector.

Dauerhafter Unternehmenserfolg ist nur mit einer fortschrittlichen Instandhaltung zu erzielen. Durch den enormen Kostendruck infolge der Globalisierung und die Innovationssprünge auf der technischen Seite wird auch die Frage nach der modernen Organisationsform für die Instandhaltung gestellt. Eine Möglichkeit der Kostenoptimierung ist das Outsourcing von Instandhaltungsleistungen. Hierbei ist es unerlässlich, dass sich die Mitarbeiter zum Dienstleister entwickeln. In diesem Beitrag wird die Entwicklung der InfraServ Knapsack von einer internen Instandhaltungsabteilung hin zu einem Industriellen Dienstleister beschrieben und Aspekte der Zusammenarbeit mit externen Kunden aus der Sicht des outgesourcten Instandhalters geschildert. Es werden die wichtigen Entwicklungsschritte zur Dienstleistungsorientierung der früheren Eigeninstandhaltung aufgezeigt. Dieser Beitrag ist nicht als "Königsweg“ zu verstehen, er soll vielmehr anhand der Erfahrungen einer outgesourcten Eigeninstandhaltung Anregungen für die Entwicklung der eigenen Instandhaltungsorganisation liefern.

Full Text Available Gängige Therapieansätze zur Behandlung von Krebserkrankungen können die Spermatogenese auf unterschiedlichsten Wegen stören und zu temporärer Azoospermie oder Sterilität führen. Die Unfruchtbarkeit ist eine ernstzunehmende Langzeitnebenwirkung, die die Lebensqualität des Patienten nachhaltig einschränken kann. Bei Kinderwunsch nach erfolgreicher Krebstherapie steht erwachsenen Patienten heute eine Anzahl an assistierten Reproduktionstechniken (ART wie In-vitro-Fertilisation (IVF oder Intrazytoplasmatischer Spermieninjektion (ICSI zur Verfügung, die mithilfe von kryokonservierten Spermien durchgeführt werden können. Diese Methoden können jedoch die natürliche Fertilität des Patienten nicht wiederherstellen und sind für präpubertäre Krebspatienten ungeeignet, da diese vor Beginn der Chemo- oder Radiotherapie keine Samenprobe liefern können. Die Transplantation von testikulären Stammzellen bietet daher einen möglichen Therapieansatz zur Behandlung von Unfruchtbarkeit. Methoden zur Isolierung, Konservierung, Transplantation und In-vitro-Maturierung dieser Zellen befinden sich zur Zeit in der Entwicklung. Der vorliegende Beitrag diskutiert etablierte Methoden zur Fertilitätskonservierung bei Männern und gibt darüber hinaus einen Überblick über die neuesten Forschungsergebnisse zur Keimzelltransplantation und extrakorporalen Generierung von Keimzellen.

Full Text Available Wie wissen Soziologinnen und Soziologen, was sie wissen? Trotz der Internationalisierung der Soziologie bestehen nach wie vor starke sprachräumliche Unterschiede in der soziologischen Wissensproduktion, in eingesetzten Theorien, Methoden und Fragestellungen. Der nachfolgende Beitrag erläutert die Entwicklung und Ausprägung der Unterschiedlichkeit soziologischer Wissenskulturen im Hinblick auf den Einsatz qualitativer bzw. interpretativer Ansätze seit den 1960er Jahren in Deutschland und Frankreich. Er stützt sich auf ein von uns 2012-2014 geleitetes Forschungsprojekt und dessen empirische Grundlagen: Dokumentenanalysen und Interviews. Wissenskulturen werden als die Arten und Weisen der Produktion und Legitimation von (hier: soziologischem Wissen verstanden. Diesbezüglich lässt sich von der Erkenntnisproduktion als dem zentralen Handlungsproblem soziologischen Forschens sprechen. Während für die französischsprachige Soziologie diagnostisch von einer Lösung dieses Erkenntnisproblems durch die den Forschenden zugeschriebenen Kompetenzen und Inspirationen ausgegangen werden kann, schiebt sich im deutschsprachigen Raume eine prozedurale Legitimation durch Verfahren in den Vordergrund. Der Beitrag rekonstruiert exemplarisch die Ausgangssituation dieser Entwicklungen um die Wende zu den 1960er Jahren und bettet sie in die weitere Entfaltung der jeweiligen Soziologien ein. Er will damit zur gegenwärtigen Entwicklung einer reflexiven Soziologie beitragen. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1601145

Endometriose wird in ihrer Pathogenese bis heute nur unzureichend verstanden. Dies hat zur Folge, dass die Therapieoptionen, insbesondere die nicht-chirurgischen Behandlungen, nicht kausal ausgelegt sind und viele Fragen bei der betroffenen Patientin wie beim Arzt offen bleiben. Gerade das genaue Verständnis der frühen Phasen der Endometrioseentstehung und ihrer molekularen Vorgänge wären aber in der Entwicklung neuer nicht-chirurgischer Behandlungspläne sehr hilfreich und dringend nötig.

The Prevalence of Power-Sharing: Exploring the Patterns of Post-Election Peace Die Verbreitung von Power-Sharing: Bedingungen für eine friedliche Entwicklung nach Wahlen

Directory of Open Access Journals (Sweden)

Anna K. Jarstad

2009-01-01

Statistiken aus der Post-Accord Elections (PAE Datensammlung, die in diesem Artikel präsentiert werden, haben gleichwohl ergeben, dass Frieden, Power-Sharing und Demokratie eng miteinander verflochten sind; Friedensabkommen sehen heute in den meisten Fällen sowohl Power-Sharing als auch Wahlen vor. Im Gegensatz zu früheren Forschungen, die von der Annahme ausgingen, das Power-Sharing ein Instrument zur Beendigung von Gewalt darstellt, belegen die Daten, dass der Konflikt häufig nach Unterzeichnung eines Abkommens fortlebt, auch wenn Regelungen zur Machtteilung vorgesehen sind. Dass Power-Sharing Wahlen begünstigt, lässt sich nicht belegen; im Gegenteil, es kommt häufiger vor, dass nach einem Friedensprozess ohne Power-Sharing-Abkommen Wahlen abgehalten werden. Eine Periode der Machtteilung vor Wahlen scheint eine anschließende friedliche Entwicklung nicht zu fördern; Wahlen sind in diesem Fall ähnlich konfliktreich wie Wahlen, die nach Friedensvereinbarungen ohne Machtteilungsklauseln abgehalten wurden. Als gute Nachricht kann gelten, dass Power-Sharing keinen negativen Effekt auf eine friedliche Entwicklung nach Wahlen zu haben scheint.

Full Text Available Der Beitrag reflektiert am Beispiel wirtschaftskategorialer Systeme den Status quo bezogen auf die Implementierung des normativen Nachhaltigkeitsgedankens in curriculare Strukturen und fachdidaktische Konzepte ökonomischer Bildung. Dazu wird die These entwickelt, dass eine einseitig auf neoklassische Kategorien ausgerichtete Wirtschaftsdidaktik eine nur unzureichend fundierte Plattform darstellt, um wirtschafts- und nachhaltigkeitsbezogene Probleme angemessen diskutieren, bearbeiteten und lösen zu können. Es wird gezeigt, dass die im Modus von wirtschaftkategorialen Struktureinsichten angebotene Objektseite ökonomischer Bildung zu eng angelehnt ist an die Modelle der neoklassisch geprägten Wissenschaftssystematik. Es bedarf hier nachdrücklich einer Erweiterung der an den Logiken neoklassischer Modellierungen orientierten stoffkategorialen Systeme um soziale und ökologische Faktoren bzw. um Kategorien aus dem Nachhaltigkeitsdiskurs, wie z.B. Vernetzung, Gerechtigkeit, Globalität, Zukunft, Kommunikation und Partizipation. Als Grundlage für die Entwicklung wirtschaftskategorialer Systeme und zur fachwissenschaftlichen Fundierung curricularer Konstruktionen ökonomischer Bildung im Sinne der Nachhaltigkeitsidee wird ein interdisziplinärer Zugang sowie ein Rekurs auf alternative ökonomische Referenztheorien bzw. -modelle empfohlen.The article reflects on the status quo with regard to the implementation of the normative sustainability-idea in curricular structures and didactical concepts of economic education using the example of economic-categorical systems. Accordingly, it is not appropriate to discuss and treat economical and sustainable problems through an economic didactic which is based upon neoclassical categories in biased way but to demonstrate that the economical categories intensively refer upon the models of neoclassical economy.

Im Beitrag werden – ohne einen Anspruch auf Vollständigkeit – Forschungszugänge für (Gestaltungs- Kompetenzen, Curricula, fachdidaktische Konzepte, Lehr-Lern-Arrangements, die Leistungserfassung und die lehrenden Akteure skizziert. Eröffnet werden einige wirtschaftsdidaktische Forschungskorridore, die für eine Bildung für nachhaltige Entwicklung in der ökonomischen Bildung von Interesse sein könnten. Ausgangspunkt ist die Überlegung, dass die ökonomische Bildung erst durch die Auseinandersetzung mit Nachhaltigkeit ihren Bildungsauftrag erfüllt.Although the discourse about sustainability has intensified over the last few years, this topic still does not get sufficient attention from the point of view of economical didactics. In this article, the writer outlines different research approaches for competences of organization, curricula, concepts of technical didactics, classroom arrangements that involve teaching and learning, the assessment of performances and the learning individuals. This contribution is not exhausting and therefore might be subject to amendments in the future. The writer presents a number of research approaches that seem to be promising for gains within the field of education for sustainable development and vocational education. As a starting point, the writer deems important that economical education can only fulfill its mission goals through an intense discourse about sustainability.

Modern plant management in the competitive market

Fischer, B.; Franke, U.; Freitag, J.U. [E.ON Kraftwerke GmbH, Hannover (Germany)

2002-07-01

Forced by the deregulation of the energy market and the big drop of electricity prices E.ON Kraftwerke was completely reorganised. Small, flexible units that are focussed on their key tasks were formed. Costs for electricity generation in our plants were reduced. Power plants that are currently not economically efficient are temporarily shut down. Power plants that are permanently not economically efficient are totally shut down. We have now reached a point at which energy prices slowly start to rise again. With our new plant management organization we have a lasting effect on further successfully operating power plants and a positive development of our company. Looking into the future does not create fear about what to do but positive believe that we will soon start new projects. This is the fundament for a stable, successful power plant company. (orig.) [German] Unter dem erheblichen Kostendruck, dem alle Energieversorger derzeit ausgesetzt sind, wurde die Aufbauorganisation von E.ON Energie grundlegend veraendert. Bei E.ON Kraftwerke wurden durch die Schaffung kleiner, flexibler Einheiten und eine klare Konzentration auf das Kerngeschaeft die Kosten fuer die Stromerzeugung in den eigenen Anlagen deutlich gesenkt. Die Auslastung vorhandener wirtschaftlicher Bloecke ist durch die Konservierung von derzeit nicht wirtschaftlichen bzw. durch die Stillegung langfristig nicht wirtschaftlicher Anlagen erheblich verbessert worden. Nachhaltig wurde damit eine Betriebsfuehrungsstrategie entwickelt, die den Bestand und eine positive Entwicklung der Kraftwerksgesellschaft sichert. (orig.)

Full Text Available Computerspiele sind heute aus der digitalen Medienwelt nicht mehr wegzudenken. Ihre rasante technische Entwicklung sowie ihre hohe Akzeptanz in der Jugendkultur werfen Fragen nach pädagogischer Verwertbarkeit dieses Mediums auf. Auf diesem Gebiet besteht Forschungsbedarf: Für den Einsatz aktueller Spielkonzepte als Lehrmittel existieren keine fundierten Theorien oder Konzepte. Der schöpferische Umgang mit Spielen durch Anwender («Emergent Gameplay» bietet hier durch sein hohes Motivationspotential einen vielversprechenden Ansatz. Die oft wenig beachtete Rolle der digitalen Spielen zugrunde liegenden Softwaretechnik sollte stärkere Berücksichtigung finden: Es existiert einerseits ein für die Akzeptanz beim Anwender notwendiges Minimum, andererseits ist der Einsatz des aktuellen technischen «state of the art» für die Umsetzung pädagogischer und didaktischer Ambitionen durch seine enormen Anforderungen wenig zielführend. Im Ergebnis sind Idee und Spielspass das Mass auch für Anwendungen des Game Based Learn­ing.

Full Text Available Die Nachvollziehbarkeit und Reproduzierbarkeit wissenschaftlicher Erkenntnisse basiert zunehmend auf digitalen Daten. Deren Publikation, Verfügbarkeit und Nachnutzung muss im Rahmen guter wissenschaftlicher Praxis gewährleistet werden. Das Projekt RADAR geht diese Herausforderung durch die Etablierung einer generischen Infrastruktur für die Archivierung und Publikation von Forschungsdaten an. Dafür vereinen fünf Projektpartner aus den Informations- und Naturwissenschaften (FIZ Karlsruhe, TIB in Hannover, KIT/SCC, LMU München und IPB Halle ihre Kompetenzen. Durch enge Kooperation mit Wissenschaftler/innen, Datenzentren, Fachgesellschaften und Verlagen wird eine bedarfsgerechte Entwicklung der Infrastruktur sichergestellt. RADAR richtet sich an zwei Zielgruppen: Projekte (d. h. Forscher/innen und Institutionen. Es verfolgt dabei einen zweistufigen Ansatz: ein disziplinübergreifendes Einstiegsangebot zur formatunabhängigen Datenarchivierung mit minimalem Metadatensatz und ein erweitertes Angebot mit integrierter Datenpublikation. Der thematische Schwerpunkt  liegt bei den wissenschaftlichen Disziplinen  im „long tail of science“, in denen Forschungsdateninfrastrukturen meist noch fehlen. RADAR erlaubt eine temporäre oder – im Falle einer Datenpublikation – eine zeitlich unbegrenzte Datenarchivierung. Das angestrebte Geschäftsmodell zielt auf einen sich selbst tragenden Betrieb mit einer Kombination aus Einmalzahlungen und institutionellen Angeboten ab. RADAR ist als Baustein der internationalen Informationsinfrastruktur geplant, der sich über Schnittstellen auch in weitere Datenmanagement-Dienste Dritter integrieren lässt. The transparency and reproducibility of scientific results are increasingly based on digital data. In compliance with good scientific practice data need to be published, accessible, and re-usable. The RADAR project aims to establish a generic infrastructure, which will provide archiving and publication

Full Text Available Sprachwissenschaftliche Untersuchungen lassen darauf schließen, dass die historischen Dialekte der alten Hellenen erst auf griechischem Boden um und nach 1000 v. Chr. entstanden sind. Bei den frühen Zuwanderern kann es sich nur um kleinere Verbände gehandelt haben, so daß zweifelllos keine großen „Stämme“ nach Griechenland vorgedrungen sind, wie man in der älteren Forschung angenommen hat. In Griechenland haben die Zuwanderer die Suffixe -ss und -nth oder -nd nicht erst kennengelernt, sondern zumindest zum Teil schon mitgebracht und vermutlich im 3. Jahrtausend v. Chr. die allmähliche Entwicklung des späteren Griechischen eingeleitet. Impulse für die Entwicklung der materiellen Kultur gingen um 1700 v. Chr. von Kreta aus und beeinflussten in starkem Maße die mykenische Zeit mit ihren Palastsystemen, deren Zusammenbruch um 1200 v. Chr. aber nicht schon zum Ende der mykenischen Kultur führte, wenn auch die Linear B-Schrift nicht mehr benutzt wurde und die Infrastrukturen der Machtzentren zusammenbrachen. Dies war zugleich die Voraussetzung für die Bildung kleinerer Siedlungen mit neuen Führungssystemen und Sozialstrukturen sowie mit einem jeweils eigenen Identitätsbewußtsein.

Full Text Available Nathalie Friedrichs proposes the following lesson plan for the senior classes of the German Gymnasium (grammar-school: „Die Entwicklung eines nationalen Identitätsbewusstseins in den von Napoleon besetzten Ländern“ (The Development of a National Sense of Identity in the Countries Occupied by Napeoleon.The central question, however, is whether this new German national consciousness at the dawn of the 19th century can be traced back to Napoleon’s reign in the Rhineland region or whether it emerged during the wars of liberation as a result of a firm rejection of Napoleon.The following materials will be given to the pupils beforhand: A short preparatory text with essential background information, a pithy quote , and two historical sources, namely the appeal of Ludwig Adolf Peter Graf von Sayn-Wittgenstein to support the war of liberation, and another more francophile source by the physician Adolf Kußmaul. The latter source points in the direction of a positive experience during the time of French occupation and therefore relativises the claim of a German patriotism as a direct result of the war against France. From a didactical viewpoint, the lesson aims to develop the prerequisites for a critical analysis of historical source texts and different points of view on the topic. Finally, a table listing the respective pros and cons of the Napoleonic arguments is sketched out, visualising the perspectives of the students and leading to the final discussion, which should produce answers to the questions of the role of Napoleon for the Germans.

With the background of the threatening global warming that requires a reduction of greenhouse gas emission by 20 % until 2010 und by 80% until 2050 in Germany, t is reasonable to consider local or municipal climate protection activities. A climate protection politics ''from the bottom'' is not only contributing to a real greenhouse gas reduction, but also triggering the stagnant international climate politics and enhances the sustainable development on a local level. Due to this fact amongst others the Enquete commission of the German Bundestag ''sustainable energy supply under the conditions of globalization and liberalization'' identifies the municipal climate protection activities as important part within the mix of measures that will allow the initiation of an alteration of the actual energy system toward a sustainable energy supply in the long-run. The consequences of globalization and liberalization on the municipal level have not yet been discussed or considered by the Enquete commission. This thesis analyses the conditions induced by the globalization and liberalization on the municipal climate protection activities as constituent of a sustainable energy supply. The project is focusing on the municipal actors and the public utility companies as central point of the considerations. [German] Vor dem Hintergrund einer drohenden globalen Erwaermung, die eine Reduktion der klimawirksamen Treibhausgase bundesweit um 20 % bis 2010 und um 80 % bis 2050 noetig macht, sind Klimaschutzaktivitaeten auf einer lokalen oder kommunalen Ebene in mehreren Dimensionen sinnvoll. Den tatsaechlichen, bezifferbaren Reduktionen von CO2, die hier geleistet werden, gesellt sich ein ''vorbildhafter'' Druck auf eine stockende internationale Klimapolitik hinzu, ebenso leistet die ''Klimaschutzpolitik von unten'' einer nachhaltigen Entwicklung der lokalen Ebene durch Lerneffekte Vorschub.

kann man daher sagen, dass das Verkehrssystem nicht nachhaltig ist und kuenftig noch weniger nachhaltig sein wird. Es muessen daher Massnahmen ergriffen werden, die zu einer Verringerung der negativen Effekte des Verkehrs fuehren und versuchen, die Abhaengigkeit von den fossilen Brennstoffen als Hauptenergiequelle zu reduzieren. Die wesentlichen Ziele der vorliegenden Arbeit sind daher: - Analyse des Energieverbrauchs des Verkehrssektors und der daraus entstehenden Probleme. - Analyse der Nachhaltigkeit bestehender Verkehrssysteme. - Definition eines nachhaltigen Verkehrs in Stadtgebieten. - Analyse alternativer staedtebaulicher Planungsphilosophien. - Erarbeitung eines Modells mit Massnahmen fuer eine nachhaltige Entwicklung des Verkehrs und des Energieverbrauchs. - Anwendung des entwickelten Modells auf die Stadt Alexandria in Aegypten. Hierfuer wurden fuer das Jahr 2015 vier unterschiedliche Szenarien entwickelt. Die Szenarien wurden untereinander sowie mit dem Prognosennullfall ('business-as-usual') verglichen.

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.

Mycotic aneurysms of the aorta and the visceral arteries are life-threatening diseases, due to potential rupture and organ or limb ischemia. They occur in endocarditis, immunodeficiency, bacteremia and fungemia, and have a poor prognosis.We report on a case of a 54-year-old male patient suffering from abdominal angina after mitral valve replacement for septic mycotic endocarditis. In presence of a mycotic-embolic occlusion of the left popliteal artery and multiple septic organ infarctions a mycotic aneurysm of the superior mesenteric artery was found in abdominal spiral-CT.Based on sequential spiral-CT examinations, this case demonstrates the development of a septic aneurysm of the superior mesenteric artery. (orig.) [German] Mykotische Aneurysmen der Aorta und ihrer Aeste stellen wegen Rupturgefahr und moeglicher Minderperfusion von Organen und Extremitaeten eine lebensgefaehrliche Erkrankung mit unguenstiger Prognose dar.

Innerhalb des Projektzeitraums konnte im Rahmen einer erfolgreichen internationalen Kooperation mit dem ICLIPS-Modell ein detailliertes integriertes Modell des globalen Klimawandels ('Integrated Assessment Model', IAM) erstellt werden. Damit ist es der deutschen Klimafolgenforschung gelungen, in diesem fuer die praktische Politikberatung wichtigen Forschungsfeld Anschluss an die internationale Entwicklung zu finden und in wichtigen Teilbereichen eine fuehrende Rolle zu uebernehmen. Das ICLIPS-Modell enthaelt eine Reihe von Innovationen, die es von anderen intertemporal optimierenden Modellen absetzt. Erwaehnenswert sind hierbei unter anderem ein numerisch hoechst effizientes Klimamodell, das alle relevanten Treibhausgase beruecksichtigt, eine Vielzahl von Klimawirkungsfunktionen ('Climate Impact Response Functions', CIRFs), die klimabedingte Veraenderungen der natuerlichen Vegetation, der landwirtschaftlichen Ertraege und der Wasserverfuegbarkeit beschreiben sowie ein Modell der langfristigen oekonomischen Entwicklung, das erstmalig kostendaempfende Effekte des technologischen Lernens mit einbezieht.

Furthering of innovation processes in the sense of lastingly sustainable development demands recognizing existing obstacles and points where furtherance might be beneficial. The search for strategies and points of attack needs to start from existing attitudes and patterns of behaviour (commission of inquiry, 1997). This comprises implementation-oriented offers to enterprises, and offers taking needs into account. Within the framework of its energy conservation and climate protection policy, the state of Hessen furthers employment-accompanied qualification of planning and executing vocational groups as well as users in energy efficiency. The IMPULS programme of Hessen, a programme instituted by the ministry for the environment, energy, youth, family and health affairs of Hessen, organizes seminars on 'rational use of electric power' enabling decision-makers to inform themselves on energy-saving measures and to exchange their knowledge. Enterprises with a potential for in-house energy conservation have a great interest in hints and support to be rapidly transformed into action. (orig.)

Full Text Available Der Reader ist aus der Internationalen Frauenuniversität 2000 entstanden und versammelt Beiträge zum Entwurf einer lebenswerteren Stadt. Er stellt die Geschichte der Geschlechter-Diskussion und die Probleme dar, die das urbane Leben speziell bezüglich der sozialen Rollenverteilung der Geschlechter bereithält. Man gewinnt einen Überblick über die Entstehung und aktuelle Facetten der Relation des Dispositivs „Stadt“ zur Geschlechter-Prägung. Tatsächlich steht allerdings der „Discourse on Women, Urbanism and Architecture“ im Mittelpunkt. Neuere Positionen zum problematischen „Gender“-Begriff und zur Frage nach dem Subjekt der Macht werden zwar referiert, aber nicht weitreichender in die kritischen Beiträge eingearbeitet. Eher Antworten auf akute soziale Probleme suchend als theoretische Entwürfe fortführend, bieten sie informative Denkanstöße für die Entwicklung einer nachhaltig gerechteren Stadt.The essays collected in this volume arise from the International Women’s University in 2000. Its contributions discuss conceptions of a city worth living in. Apart from describing the history of gender debates concerned with the city, the essays centre particularly around problems that urban life creates with regard to the division of social gender roles. The book shows the development and the different faces of a gender encoded city. However, despite expectations raised by the title, the book focuses on discourses on women, urbanism and architecture more than on gender. The contributors do refer to recent theories on gender and the “empowered subject”, but fail to integrate them into their actual analyses. Looking more for answers to severe social problems than to develop new theoretical questions, the book does nonetheless provide some good ideas for a sustainably fair city.

Emissions trading in the context of the Kyoto Protocol becomes increasingly important for solid waste management projects in developing and emerging countries. Compared with the emissions of the applied so called ''baseline'' in such countries, significant reductions of one of the most harmful greenhouse gases, methane, can be realized just by means of collecting and treating (controlled combustion) landfill gas. Even stronger reductions can be achieved by means of pre-treating of solid wastes. Revenues generated by sales of emission-reductions can cover up to 20-30% of the cost of an environmentally sound solid waste management system. However advanced solid waste technologies can currently only be applied under specific conditions (e.g. in Metropolitan cities) due to the limited willingness and ability of the waste producers to pay higher fees required by such systems.

The main goal of the interdisciplinary research syndicate was to develop integral strategies for overcoming the water availability problems and conflicts of water use following in the wake of global change as well as the environmental and socio-economic problems resulting from this in the Elbe catchment area. To negotiate this task the Integrative Methodological Approach of GLOWA-Elbe (IMA) was developed and applied. The entire river system of the Elbe served as study region. The study also included an intensive substudy focussing on water quality problems of the Unstrut river system as well as an analysis of the momentous surface water availability conflicts in the Spree catchment area which was performed for the Upper Spree and Spree Forest subregions (cf. Dietrich et al. 2004) and Berlin (cf. Finke et al. 2003). The project on the Upper Spree subregion, performed as part of GLOWA Elbe, was dedicated to an analysis and assessment of the Upper Spree subregion where, as a result of the decade-long history of brown coal mining in that area, one of Germany's greatest surface water availability and quality conflicts has evolved. It was in the context of this subregion project that IMA was developed and tested. The present outcome report presents the more important water management and socio-economic results of this subregion project, though various results from other part-projects of GLOWA Elbe have also been incorporated. Reports dealing with individual aspects of the GLOWA Elbe project in greater detail have been published elsewhere. Interested readers are referred to the GLOWA Elbe website at http://www.glowa-elbe.de and to the PIK report. The latter report contains, in various places, references to further literature on the Upper Spree subregion project.

When liberalisation of the German energy markets was first initiated, several utilities made attempts at establishing their own brands. These tactical attempts were frequently restricted to images intended to visualise their product offerings, which were born of the new competitive situation in the liberalised energy markets. The value of a brand can only be sustainable when its recognition, established associations and product quality have been built up in integrated fashion. These elements aid in preparing the field for exploiting new sources of income through new and innovative products. (orig.) [German] Zu Beginn der Liberalisierung des deutschen Energiemarktes haben einige EVU Versuche in der Markenfuehrung unternommen.

First, a simple and efficient tool for projecting solar thermal power systems was to be developed by ITW Stuttgart (see separate ITW Stuttgart report). Parallel to this, a fast and simple method was to be developed for in-situ assessment or the annual yield of such systems, with a maximum error of 5 percent. The following steps were taken: 1. Development of a measuring system for the task; 2. Selection of methods of evaluation for the dynamic in situ short-term test; 3. Development and testing of the method in several industrial-scale systems and validation by comparison with the results of conventional measurements. The dynamic in situ short-term test method developed on this basis consists of six steps which are described in the report. The measuring accuracy depends on the correct function of the plant. [German] Zunaechst sollte fuer solarthermische Grossanlagen ein Katalog standardisierter Anlagenkonfigurationen erstellt und anschliessend in die gaengigen Planungswerkzeuge TRNSYS und TSOL uebertragen werden, um Planern ein einfaches und leistungsfaehiges Werkzeug zur Auslegung und zur Berechnung des GSR zur Verfuegung zu stellen. Damit sollen Planungsfehler aufgrund fehlender Erfahrung mit Solaranlagen vermieden und ein Standard fuer innovative Anlagenkonzepte verbreitet werden. Dieser Arbeitspunkt wurde ausschliesslich durch das ITW Stuttgart bearbeitet, siehe separater Berichtsteil des ITW Stuttgart. Parallel dazu war ein Testverfahren zu entwickeln, mit dem der Jahresertrag grosser thermischer Solaranlagen in situ, d.h. an der installierten Anlage vor Ort, ohne Eingriff in die Anlage, um die Gewaehrleistungspflicht des Anlagenbauers zu erhalten, auf 5% genau, um ein klares juristisches Kriterium fuer die Feststellung einer etwaigen Nachbesserungspflicht des Erbauers zu haben, kostenguenstig und in kurzer Zeit (maximal 6 Wochen) bestimmt werden kann. Hierzu waren folgende Arbeiten notwendig: 1. Entwicklung einer an die Aufgabenstellung angepassten Messtechnik

Zusammenfassung Hintergrund Persistierende Infektionen mit humanen Papillomviren sind die notwendige Ursache des Zervixkarzinoms. Die Entwicklung von HPV-basierten Präventionsverfahren, der HPV Impfung und der HPV-Testung, führt derzeit zu umfangreichen Veränderungen von Zervixkarzinom-Vorsorgeprogrammen. Eine Dekade nach Einführung der HPV-Imfpung in vielen Ländern werden bereits Reduktionen von HPV-Infektionen und Krebsvorstufen in jungen Frauen beobachtet. Der Fokus liegt jetzt auf der Integration von neuen Testverfahren im Screening von Populationen mit zunehmenden Impfraten. Ergebnisse und Schlussfolgerung Ein erfolgreiches Zervixkarzinom-Vorsorgeprogramm besteht aus verschiedenen Komponenten, vom primären Screening über die Triage zur Kolposkopie mit Biopsie, um Frauen mit Kresbvorstufen zu identifizieren, die eine therapeutische Intervention benötigen. Im primären Screening wird eine kleine Gruppe von Frauen mit erhöhtem Risiko für eine Krebsvorstufe identifiziert, während die grosse Mehrheit kein erhöhtes Risiko hat. Je nach primärem Testverfahren werden in screen-positiven Frauen zusätzliche Triage-Tests durchgeführt, um zu entscheiden, wer zur Kolposkopie überwiesen werden sollte. Derzeit gibt es drei verschiedene Ansätze für das primäre Zervixkarzinomscreening: Die Zervix-Zytologie, die HPV-Testung, und die HPV-Zytologie Ko-Testung. Zahlreiche Triage-Tests für HPV-positive Frauen werden derzeit untersucht, darunter sind die Zytologie, HPV-Genotypisierung, p16/Ki-67 Zytologie, und diverse Methylierungstests. Die steigende Anzahl an Optionen für die Früherkennung des Zervixkarzinoms stellt eine Herausforderung für klinische Leitlinien dar. Die zunehmende Komplexität von Vorsorgeprogrammen kann zur Verunsicherung von Ärzten und von am Screening teilnehmenden Frauen führen. Die Präzisions-Prävention des Zervixkarzinoms ist eine neuer Ansatz, der umfangreiche Risikodaten basierend auf der individuellen Vorgeschichte und von

This report completes the documentation for the research project 'High Pressure Compressor - Preliminary Design as Basis for the Development of an Efficient and Environmentally Friendly Core Engine' which was funded by the Ministry of Economics of State Brandenburg. The objective of the project is to deliver a preliminary compressor aerodynamic design as well as design studies for an efficient, weight and cost improved compressor. The increase of stage pressure ratio and improved efficiency, whilst stage and blade count is reduced, has been achieved by advanced 3D methods. Compressor stability also at off-design conditions will be retained. The mechanical design focusses on a cost and weight optimised rotor not only for a conventional bladed discs but also for Blish stages. Various options for split casings have been developed and assessed. Alternative vortex reducers based on different design options have been carried out. The results from this project will be directly exploited in a follow-on project for a new nine-stage compressor. The new high pressure compressor will be a key element of the future two-shaft-engine architecture. (orig.)

Parallel to the expansion of automobility, the country has been unique in its development of innovations in electric-powered two-wheelers and a vibrant e-cycling practice since the 1980s. Electric bikes have given over 300 million low-status commuters and peddlers access to jobs and housing, even though planners have dismissed them as a problematic ›floating population‹ and remnants of the past. Given China’s current urban sustainable mobility challenges and ambition to become the world’s first ›Ecological Civilization‹ (2013, China’s bicycle industry, e-vehicle manufacturers, and the e-commerce sector may offer an alternative to the US-based ›car civilization‹ if ecological (e-cycles and social (low-status workers sustainability are brought into one analytical frame. *** Seit den 1950er-Jahren hat die chinesische Fahrrad-Politik drei Phasen durchlaufen: von aktiver Förderung (1955–1994 über systematische Behinderung (1994–2008 bis zu Vernachlässigung und Ambivalenz (ab etwa 2010.

A fast development of the screw machines leads to the investigation of the physical processes, which take place in the work space of the screw machine and in the gaps on its boundary. These processes have a great influence on the performance of the screw machine especially with regard to its efficiency, therefore its knowledge is very important. It is necessary to turn our attention to the fluid dynamics of the screw machines. This paper deals with the preliminary analysis of the fluid flow in the screw machines. In this paper numerical computation of the compressible inviscid fluid flow in the work space of the screw machines and through the sealing gaps which are situated between the stator and the head of the female rotor tooth, is presented. The mathematical model of two- and three-dimensional inviscid compressible flow is described by the conservative system of the Euler equations. This problem was solved by the cell-centred finite volume method on a structured quadrilateral mesh. (orig.) [German] Die schnelle Entwicklung der Schraubenmaschinen fuehrt zur Notwendigkeit einer Untersuchung der physikalischen Vorgaenge, die im Arbeitsraum und in den arbeitsraumbegrenzenden Spalten der Schraubenmaschine ablaufen.

Einen Ausgangspunkt fuer die Analyse stellen die Kenntnisse im Bereich der kompressiblen Fluide dar. Der Zustand kann vor allem durch das Geschwindigkeits-, Druck-, und Temperaturfeld beurteilt werden. Der Beitrag beschaeftigt sich mit der Problematik der Stroemungsuntersuchungen des Gases im Arbeitsraum der Schaubenmaschine und im Gehaeusespalt.

The lack of harmonization among the fields of environmental policy, energy policy, and economic policy in Germany is obvious. Returning to a basic consensus in energy policy, with an unbiased evaluation of all energy resources, is an indispensable step for all those to whom ecology is a truly serious concept. The positions of all energy resources must be assessed with a view to national and international developments. No source of primary energy must be excluded from that review. Nuclear power remains one of the important options in the energy mix especially from the points of view of CO{sub 2} avoidance and preventive protection of the climate. A leading industrialized nation, such as the Federal Republic of Germany, ought to be able, in the more and more important discussion about globally sustainable development, to return to a consensus across all political parties at least about the back end of the nuclear fuel cycle. Or should the philosopher, Sir Karl Popper, finally be proven right in his statement that those wanting to establish a paradise on earth must be careful not to create hell? (orig.) [Deutsch] Der Abstimmungsmangel zwischen Umwelt-, Energie- und Wirtschaftspolitik in Deutschland ist unuebersehbar. Die Rueckkehr zum energiepolitischen Grundkonsens mit einer vorurteilsfreien Bewertung aller Energietraeger ist fuer solche, die es mit der Oekologie wirklich ernst meinen, unverzichtbar. Der Stellenwert aller Energietraeger muss im Hinblick auf nationale und internationale Entwicklungen ueberdacht werden; eine Tabuisierung einzelner Primaerenergietraeger darf es nicht geben. Insbesondere unter dem Aspekt der CO{sub 2}-Vermeidung und des vorsorgenden Klimaschutzes ist und bleibt die Kernenergie eine bedeutende Option im Energie-Mix. Im Rahmen der allgemein an Bedeutung gewinnenden Diskussion ueber eine global nachhaltige Entwicklung sollte es einer fuehrenden Industrienation wie der Bundesrepublik Deutschland eigentlich gelingen, zumindest hinsichtlich

Violence against children has many faces. Child physical abuse, neglect, sexual abuse and interparental violence can cause acute and permanent damage and affect children's development and their life plans in the long term. In industrialized nations almost 1 child in 10 is affected. Up to 10% of child physical abuse cases involve the central nervous system with 80% of these cases occurring during the first year of life. Worldwide more than 50,000 children die as a result of violence, abuse and neglect every year, according to the United Nations Children's Fund UNICEF. In Germany, there are about 120 cases of non-accidental head injury per year. In addition to the officially known cases there is a large grey area for all forms of violence. Recognition of these cases and the provision of help for the victims require an appropriate suspicion and understanding of the pertinent pathophysiology. Suspicion must be based on a well-documented medical history and multidisciplinary diagnostic assessment. Medical confidentiality prevents the disclosure of such information making early detection networks and guidelines for collaboration absolutely indispensable. (orig.) [German] Gewalt gegen Kinder hat viele Gesichter: Kindesmisshandlung, Vernachlaessigung, sexueller Missbrauch und elterliche Partnerschaftsgewalt koennen bei Kindern und Jugendlichen zu akuten und bleibenden Schaeden fuehren und ihre Entwicklung und Lebensentwuerfe nachhaltig beeinflussen. Betroffen ist in Industrienationen fast jedes zehnte Kind. Bis zu 10% der Kindesmisshandlungen betreffen das zentrale Nervensystem. Von diesen ereignen sich ca. 80% im ersten Lebensjahr. Weltweit sterben nach Angaben der Kinderhilfsorganisation UNICEF jaehrlich ueber 50.000 Kinder an den Folgen von Gewalt, Missbrauch und Vernachlaessigung. In Deutschland ereignen sich pro Jahr ca. 120 Faelle an nichtakzidentellen Kopfverletzungen. Den oeffentlich bekannten Faellen steht eine hohe Dunkelziffer aller Formen von Gewalt

A short-term test method for in-situ measurement of the collector field, pipelines and heat exchanger of large-surface solar systems was developed at ZAE Bayern, together with the necessary technical systems (mobile acquisition of meteorological data via telemetering, non-invasive surface temperature sensors and ultrasonic volume flow measuring instruments). Dynamic measurements were made for 11 days in a large-surface solar system of the ``Solarthermie 2000`` programme using the new measuring system. In order to optimize the evaluation procedure, the plant was simulated, and the influence of different models and operating conditions during the measurements on the prediction quality was investigated in detail. On this basis, it was possible to predict the long-term collector yield of the ZfS Hilden, which was measured for a period of 7 months, with an error of less than 5%. The method will be validated in two further industrial-scale systems. [Deutsch] Am ZAE Bayern wurde ein Kurzzeittestverfahren zur insitu-Vermessung des Kollektorkreises (Kollektorfeld, Rohrleitungen, Waermetauscher) grosser Solaranlagen entwickelt. Hierzu wurde eine der Aufgabenstellung angepasste Messtechnik entwickelt (Mobile meteorologische Datenerfassung mit Funkbetrieb, nicht-invasive Oberflaechen-Temperaturfuehler und Ultraschall-Volumenstrommessgeraete). Der Kollektorkreis einer grossen Solaranlage aus dem Programm Solarthermie 2000 wurde dynamisch ueber 11 Tage (29.10.-8.11.1997) mit der neuen Messtechnik vermessen. Zur Entwicklung eines geeigneten Auswerteverfahrens wurde die Anlage simulatorisch abgebildet und der Einfluss verschiedener Modellansaetze und der Betriebsbedingungen waehrend des Mess- und Vorhersagezeitraums auf die Vorhersageguete im Detail untersucht. Mit dem entwickelten Verfahren konnte aus der dynamischen Kurzzeitvermessung der in einer Langzeitmessung der ZfS Hilden ueber 7 Monate ermittelte Kollektorertrag nach dem solaren Waermetauscher auf deutlich besser als 5

Chirurgie angeborener Herzfehler

Schreiber, Christian; Libera, Paul; Lange, Rüdiger

Störungen der embryonalen Entwicklung in der frühen Phase der Schwangerschaft können zu Fehlbildungen am Herz- und Gefäßsystem führen. Die Häufigkeit liegt bei 0.8-1 % aller lebend geborenen Kinder. In Deutschland werden jedes Jahr etwa 6.000 Kinder mit einem Herzfehler geboren (Quelle: http://www.kompetenznetzahf.de). Das Spektrum reicht von einfachen Fehlern, die das Herz-Kreislauf-System wenig beeinträchtigen, bis zu sehr schweren Herzerkrankungen, die unbehandelt zum Tode führen. Fortschritte der Kinderkardiologie, Herzchirurgie und Anästhesie ermöglichen heute ein Überleben bei über 90 % der Patienten. Auch die spezialisierte Pränataldiagnostik (vorgeburtliche Diagnostik) ermöglicht schon die frühe Weichenstellung für mögliche Therapieoptionen. Bei der chirurgischen Therapie ist jedoch festzuhalten, dass ein Herzfehler entweder korrigierend behandelt wird oder nur "palliiert“ werden kann. Bei letzterer Therapie wird bei einem Patienten eine medizinische Maßnahme durchgeführt, die nicht die Herstellung normaler Körperfunktionen zum Ziel hat, sondern in Anpassung an die physiologischen Besonderheiten des Patienten dessen Zustand lediglich stabilisiert und optimiert. Dies kann beispielsweise bei einer nicht korrigierbaren angeborenen Fehlbildung notwendig sein, bei der lediglich eine funktionelle Herzkammer vorhanden ist (z. B. hypoplastisches Linksherz). Hierbei muss eine prothetische Verbindung zur Lungenstrombahn in der Folgezeit entfernt werden.

Future dynamics in f(R) theories

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.)

Fiber optic sensors have been developed or further developed, for specific tasks of the research project reported, as for instance detecting and signalling changes of geophysical or geochemical parameters in underground waste storage sites which are of relevance to operating safety. Such changes include e.g. materials dislocations, extensions, temperatures, humidity, pH value and presence of gaseous carbon dioxide and hydrogen. The measuring principle chosen is the fiber Bragg Grating method, as a particularly versatile method easy to integrate into fiber optic networks. After development and successful lab-scale testing of all sensors, except for the gas sensors, field test systems have been made for underground applications and have been tested in situ in the experimental Konrad mine of DBE. Most of the problems discovered with these tests could be resolved wihtin the given project period, so that finally field-test proven sensing systems are available for further activities. The report explains the system performance with a concrete example which shows inter alia beneficial aspects of the system with respect to on-site operation, and the potentials offered in establishing more direct connections between numerical safety analyses and measured results.

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.

A solar refrigerator for air conditioning and cooling was developed. The key component is a two-phase, two-component jet pump with ammonia and water as working fluid. Both the pump flow and the suction flow can be two-phase flows. This way, the advantages of both the absorption and the compression principle will be utilized, and a compact size will be achieved. Upon termination of the calculations, the function of the pump will be investigated in a 0 W pilot plant. For this, various geometries were calculated and tested for their potential efficiencies. A prototype will be constructed on the basis of the results. [German] Das Ziel des Vorhabens besteht in der Entwicklung einer solarbetriebenen Kaelteanlage fuer Klimatisierungs- und Kuehlungszwecke. Die Hauptkomponente der Kaelteanlage ist eine Zweiphasen-/Zweikomponenten-Strahlpumpe, die mit dem Arbeitsgemisch Ammoniak/Wasser betrieben wird. Sowohl der Treib- als auch der Saugstrom koennen zweiphasig sein. Dadurch sollen einerseits die Vorteile des Absorptions- und des Kompressionsprinzips miteinander verknuepft und andererseits ein kompakter Aufbau erreicht werden. Nach Abschluss der thermodynamischen und kinetischen Berechnungen soll die Funktion der Zweiphasen-/Zweikomponenten-Strahlpumpe mit Hilfe einer Pilotanlage mit ca. 20 kW Kaelteleistung untersucht werden. Dazu werden nach Vorausberechnungen verschiedene Geometrien in Bezug auf erzielbare Wirkungsgrade getestet. Die Ergebnisse bilden die Basis fuer den Bau eines Prototyps. (orig.)

The development of direct-injection gasoline engines at Volkswagen was supported strictly from the beginning by the means of optical diagnostics and CFD-simulations. Basic phenomena, such as the formation of the in-cylinder flow field, the penetration of the spray formed by a hollow-cone swirl-type injector at high fuel pressure, the interaction of spray and flow and the formation of an ignitable mixture were analysed in details. The paper describes the laser-optical techniques-particle-image-velocimetry, laser-Doppler-anemometry, videostroboscopy, high-speed cinematography and laser-induced fluorescence - which were used during the development of the DI gasoline combustion process. Examples taken from engines with optical access to the combustion chamber demonstrate the capability of the techniques and pinpoint where the design of the combustion process benefits from experimental and simulation investigations. (orig.) [German] Die Entwicklung von Ottomotoren mit Benzin-Direkteinspritzung wurde bei Volkswagen von Beginn an konsequent durch den Einsatz optischer Messverfahren und CFD-Simulationen unterstuetzt.

Drei Perspektiven werden hier aufgezeigt: erstens eine Wissenschafts- und Ideologiekritik, zweitens eine empirisch orientierte Zustandsbeschreibung städtischer Strukturen und von Stadtentwicklung sowie drittens eine Analyse der staatlichen Stadtpolitik. Diese drei abschließenden Perspektiven möchte ich im Folgenden kommentieren. Es wird mithin keine immanente Auseinandersetzung mit dem gesamten Text und weiteren Arbeiten der beiden Autoren angestrebt. Es hätte mich zwar durchaus gereizt, die Entwicklung der Arbeiten von Häußermann und Siebel vor dem Hintergrund dieses frühen, emphatisch formulierten Textes zu reflektieren. Vielleicht auch wegen der persönlichen Bekanntschaft mit Häußermann, den ich als Projekt- und Dissertationsbetreuer an der Humboldt-Universität kennenlernte, erschien mir eine solche Zugangsweise zu den „Thesen“ durchaus naheliegend.

The focus was on the development and optimisation of the close-spaced sublimation process in an inline coating plant for production of stable high-efficiency CdS/CdTe solar wafers. An inline plant was to be constructed by ANTEC GmbH and ISFH. Film layers were to be optimised, and investigations were to show whether processing of single films is possible without breaking the vacuum, e.g. for etching. The results were to be used directly by ANTEC GmbH. An efficiency of 14 percent and an idle voltage of about 850 V were to be achieved with a film thickness of 2 {mu}m. To achieve these goals, the following project stages were envisaged: 1. Replacement of the expensive window material ITO by a less costly material. 2. Higher stability of the back contact by using appropriate intermediate layers. 3. Alternative activation processes other than the conventional CdCl{sub 2} activation. 4. Investigation of the effects of the activation step on the electric properties of the sample. [German] Die uebergreifende Aufgabenstellung des Projektes war die Entwicklung und Optimierung des Close-spaced-Sublimation verfahrens in einer Inline-Beschichtungsanlage fuer die Herstellung stabiler und hocheffizienter CdS/CdTe Duennschichtsolarzellen.

Die fuer die Solarzelle notwendigen Einzelschichten sollten in dem Inline-Prozess optimiert werden. Es sollte ermittelt werden, ob eine Prozessierung der Einzelschichten ohne Brechen des Vakuums, z.B. fuer einen Aetzschritt, moeglich ist. Die erzielten Ergebnisse sollen direkt der ANTEC GmbH zufliessen. In dem Projekt wurde als Endziel ein Wirkungsgrad der CdTe/CdS-Duennschichtsolarzelle von 14% und eine Erhoehung der Leerlaufspannung auf Werte um 850 mV angestrebt. Gleichzeitig sollte die CdTe-Schichtdicke auf 2 {mu}m vermindert werden. Um dieses Gesamtziel zu erreichen, sollen folgende Teilaufgaben bearbeitet werden: 1) Das teuere

f(R) gravity solutions for evolving wormholes

Energy Technology Data Exchange (ETDEWEB)

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.

Requirements for improvement of pedestrian protection are the result of real-world accidents and test conditions, which take an important role in development of front-end structures of passenger cars at present, based on legal regulations (EU directives expected in 2005) and on car assessment programmes (application as per EuroNCAP since 1997). Styling and packaging are major considerations in conceptual realisation on a large scale. Furthermore, demands for minimisation of weight and cost have to be considered as marginal conditions. Solutions for this conflict of aims, which results from the new safety requirements and performance criteria for front-end structures, are to be represented and discussed based on concrete examples. (orig.) [German] Anforderungen zur Verbesserung des Fussgaengerschutzes resultieren einerseits aus dem Unfallgeschehen und andererseits aus Versuchsbedingungen, die derzeit auf der Basis von gesetzlichen Regelungen (erwartete EU-Richtlinie etwa im Jahr 2005) und von Sicherheitsbewertungen (Anwendung im Rahmen von EuroNCAP seit 1997) in der Vorbau-Entwicklung von Personenkraftwagen eine bedeutende Rolle einnehmen. Die konzeptionelle Umsetzung tangiert sowohl Styling als auch Packaging in erheblichem Umfang, darueber hinaus sind als Randbedingungen die Forderungen nach der Minimierung von Gewicht und Kosten zu beruecksichtigen.

Development and prototypical application of analysis methods for complex anion mixtures in waters and heavy metal organyls in sediments; Entwicklung und prototypische Anwendung von Analysenverfahren fuer komplexe Anionengemische in Waessern und Schwermetallorganylen in Sedimenten. Schlussbericht

When it comes to assessing the hazards emanating from heavy pollutants in waters mere elemental analysis provides too little information. Due to the great differences in toxicity and mobility it is important to know more about the exact species in question. This is particularly true of heavy metals that form stable organyls, specifically As, Pb, Sn and Hg, but also of alkylated arsenic acids, which need to be measured in complex anion mixtures. The purpose of the present project was to develop robust, powerful analysis methods and thus overcome the existing deficit in reliable analysis methods for these substances. An important approach in this connection is the use of coupled chromatography and detection systems for separation and analysis. [German] Hinsichtlich der von einer Schwermetallbelastung in Gewaessern ausgehenden Gefahren liefert die reine Elementanalytik nur unzureichende Aussagen. Aufgrund der grossen Unterschiede in Toxiditaet und Mobilitaet ist die Kenntnis der jeweils vorliegenden Spezies bedeutungsvoll. Dies gilt in besonderem Masse fuer die stabile Organyle bildenden Schwermetalle As, Pb, Sn und Hg sowie die alkylierten Arsensaeuren, die es innerhalb komplexer Anionengemische zu bestimmen gilt. Hinsichtlich ihrer sicheren Bestimmung bestehen methodische Defizite, die das vorliegende Projekt durch die Entwicklung robuster, nachweisstarker Analysenverfahren zu beseitigen versucht. Grosse Bedeutung kommt dabei gekoppelten Systemen aus Chromatographie und Detektion als Trenn- und Bestimmungsmethode zu. (orig.)

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

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

International Nuclear Information System (INIS)

Oyaizu, Hiroaki

2008-01-01

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

Consulting: a new area of business for energy supply utilities; Consulting - ein neues Geschaeftsfeld fuer Energieversorgungsunternehmen

Energy Technology Data Exchange (ETDEWEB)

Busse, H.; Oswald, H. [MVV-Energie AG im Internationalen Gasconsulting, Duggendorf (Germany)

2000-03-01

The radical changes in national and international markets in recent years will have a long-term effect on the future development of industry and of energy supply utilities. The dynamics and complexity of these processes are producing new challenges. These are leading to a departure from rigid structures in the supply enterprises, towards functional, process-oriented organizational structures. In addition, a whole series of new business activities is arising. One of these new strategic areas of business is consulting. In Germany, a range of regional and municipal supply utilities now offer consulting services for third parties on an intensified basis around the world. Since about 1990, larger municipal technical service organizations and regional energy supply utilities have been working on numerous projects both within Germany and abroad. It has become apparent that it is necessary to take a long breath (one to four years) from the time of obtaining the sale until the award of contract, particularly in the case of foreign projects.

THE LIFETIME AND POWERS OF FR IIs IN GALAXY CLUSTERS

International Nuclear Information System (INIS)

Antognini, Joe; Bird, Jonathan; Martini, Paul

2012-01-01

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

From the components to the stack. Developing and designing 5kW HT-PEFC stacks; Von der Komponente zum Stack. Entwicklung und Auslegung von HT-PEFC-Stacks der 5 kW-Klasse

Energy Technology Data Exchange (ETDEWEB)

Bendzulla, Anne

2010-12-22

The aim of the present project is to develop a stack design for a 5-kW HTPEFC system. First, the state of the art of potential materials and process designs will be discussed for each component. Then, using this as a basis, three potential stack designs with typical attributes will be developed and assessed in terms of practicality with the aid of a specially derived evaluation method. Two stack designs classified as promising will be discussed in detail, constructed and then characterized using short stack tests. Comparing the stack designs reveals that both designs are fundamentally suitable for application in a HT-PEFC system with on-board supply. However, some of the performance data differ significantly for the two stack designs. The preferred stack design for application in a HT-PEFC system is characterized by robust operating behaviour and reproducible high-level performance data. Moreover, in compact constructions (120 W/l at 60 W/kg), the stack design allows flexible cooling with thermal oil or air, which can be adapted to suit specific applications. Furthermore, a defined temperature gradient can be set during operation, allowing the CO tolerance to be increased by up to 10 mV. The short stack design developed within the scope of the present work therefore represents an ideal basis for developing a 5-kW HT-PEFC system. Topics for further research activities include improving the performance by reducing weight and/or volume, as well as optimizing the heat management. The results achieved within the framework of this work clearly show that HTPEFC stacks have the potential to play a decisive role in increasing efficiency in the future, particularly when combined with an on-board supply system.

Full Text Available Mit der gegenwärtigen Diskussion um Mediatisierung und Digitalisierung ist die Forderung verbunden, der Medienbildung und/oder der informatischen Bildung ein größeres Gewicht in der schulischen Bildung zu verschaffen. Dies legt die Frage nahe, wie ein produktives Verhältnis zwischen beiden gestaltet werden sollte und wie beide am besten zu einer zeitgemäßen Bildung beitragen können. Bei entsprechenden Überlegungen spielen unter anderem Entwicklungen eine Rolle, die sich seit frühen Forderungen nach einer Computerbildung im Verhältnis zur damaligen Medienerziehung herausgebildet haben. In dem vorliegenden Beitrag werden solche Entwicklungen skizziert und Schlussfolgerungen für die gegenwärtige Diskussion formuliert. Dabei kommen unterschiedliche Auffassungen zur bildungsbezogenen Auseinandersetzung mit Medien sowie mit Informations- und Kommunikationstechnologien in den Blick. Für das Verhältnis von Medienbildung und informatischer Bildung ergibt sich als zentrale Schlussfolgerung, dass sowohl eine Integration der informatischen Bildung in die Medienbildung als auch eine umgekehrte Lösung unangemessen erscheint, wiewohl beide Bereiche auf Anteile aus dem jeweils anderen Bereich angewiesen sind. Danach werden für eine Medienbildung mit informatischen Anteilen ein geeigneter Medienbegriff und eine tragfähige Bildungsauffassung sowie ein Ansatz zu einem inhaltlich-thematischen Kompetenzrahmen beschrieben. Überlegungen zur schulischen Umsetzung schließen den Beitrag ab.

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

International Nuclear Information System (INIS)

Ritchie, B.G.

1979-01-01

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

Dynamics of anisotropic power-law f(R) cosmology

Shamir, M. F.

2016-01-01

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

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 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.

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.

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

Paschalidis, Vasileios; Shapiro, Stuart L; Halataei, Seyyed M H; Sawicki, Ignacy

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.

The main goals of the project carried out at Bielefeld University on ''The fight against desertification and the remediation of the salt deserts near the Aral Sea'' were as follows: a) to test methods for counteracting desertification by phytomelioration of saline soils; b) to develop plausible nature conservation strategies for the region and preserve biodiversity; and c) to manage resources at the local and regional level. Ad a) The planting was done in November 2002 and March 2004 on an area of 248.3 ha. Three species were tested: Haloxylon aphyllum, Halocnemum strobilaceum and Tamarix hispida. Various planting methods were used. Ad b) A model for preserving biodiversity in the region was developed using the nature conservation area Barsa Kelmes as an example. The flora and vegetation of the core area (the former island Barsa Kelmes) were inventoried, and measures were taken to develop the above-named nature conservation area. Ad c) The villages Bogen and Karateren were used as model objects for cooperation within the region. These villages belong to the Aralsk region (Raion). They are the administrative centres of their respective sub-districts (Aulsoviet), Karateren and Bogen. An intensive cooperation has evolved with the relevant NGOs. In the village Bogen a bureau for the NGO and an information centre for nature resource conservation were established.

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

Science.gov (United States)

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.

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.

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

f(R) gravity, torsion and non-metricity

International Nuclear Information System (INIS)

Sotiriou, Thomas P

2009-01-01

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

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

Directory of Open Access Journals (Sweden)

Qian Liu

2016-09-01

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

The author of the paper is Dr. Frithjof Kublik, Vice President of Shell Solar (Global) and division manager 'Renewable Energies' of the German Shell AG. He discusses very comprehensively the results of a study performed on behalf of the Shell company. The study encompasses two scenarios based on the same predicted growth of the global human population from 1999 until 2060, and the resulting global demand for energy, but assuming different levels of market penetration and technological development of power generation from RES. Their respective final energy balance statements are very different. The scenario 'sustainable development' predicts market shares of renewable energy sources up to 50% of global demand, whereas the scenario 'dematerialization' predicts a maximum of 30%. (orig./CB) [German] Der Beitrag erlaeutert eine Studie der Firma Shell AG, die zwei Szenarien - 'Nachhaltiges Wachstum' und 'Dematerialisierung'- umfasst. Beide Szenarien gehen von der gleichen Bevoelkerungsentwicklung (zehn Milliarden Menschen im Jahre 2060, gegenueber fuenf Milliarden in 1990) und von dem gleichem Wirtschaftswachstum (drei Prozent pro Jahr) aus, die Energiebilanz sieht jedoch unterschiedlich aus. In beiden Szenarien werden sich die regenerativen Energien im Rahmen eines Reifeprozesses weiterentwickeln, indem sie zunaechst Marktnischen besetzen und sich dann mit unterschiedlichem Erfolg im Markt durchsetzen. Im Szenario 'Nachhaltiges Wachstum' geht die Studie davon aus, dass Produktivitaetsfortschritte bei der Energiebereitstellung zu einem erheblichen Angebot an regenerativen Energietraegern fuehren wird (bis zu 50% des Weltbedarfs).

Mit Verfahren zur partizipativen Produktentwicklung (PPE können sowohl das kreative Potenzial von Nutzer/innen für die Produktentwicklung erschlossen als auch marktfähige nachhaltige Produkte entwickelt werden. Sie ermöglichen so aktives Nachhaltigkeitsmanagement. Am Beispiel des INNOCOPE-Pilotverfahrens wird diskutiert, wie nachhaltigkeitsbezogene Lernprozesse in PPE-Prozessen initiiert werden können und welche Faktoren dabei wesentlich sind. Insgesamt zeigt sich, dass vor allem die sich wiederholende, direkte und möglichst gleichberechtigte Interaktion von Unternehmensvertreter/innen und von Konsument/innen einen themenbezogenen Wissensaustausch und wechselseitige Lernprozesse ermöglicht. Dabei sind der inhaltliche Aufbau der Treffen und der zeitlich gestaffelte Einsatz von Lernmethoden wesentlich.Today, market observation and customer surveys alone do not suffice to develop successful and sustainable products. Methods of participatory product development (PPD allow to open up the creative potential of users for product development, and to develop marketable sustainable products. Thereby, they support active sustainability management. Taking the INNOCOPE pilot process as an example, we discuss the possibilities and the relevant factors to initiate sustainability- and climate-related learning processes within PPD processes. Our findings indicate that repeated, direct and equitable interaction between company representatives and customers are fundamental for relevant knowledge exchange and mutual learning processes. Other key issues are the thematic structure of the meetings and the timing of learning methods.

f(R) gravity cosmology in scalar degree of freedom

2014-01-01

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

2017-06-01

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

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

CERN Multimedia

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

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

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

Cosmological reconstruction of realistic modified F(R) gravities

International Nuclear Information System (INIS)

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

2009-01-01

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

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.

„Das Leben ist nur ein Spiegel“ – Schopenhauers kritischer Lebensbegriff

Matthias Kossler

2012-09-01

Full Text Available http://dx.doi.org/10.5007/1677-2954.2012v11nesp1p1   Schopenhauer gilt als Vorreiter oder erster Vertreter der Lebensphilosophie, wie sie später von Dilthey, Nietzsche, Bergson und anderen entfaltet wurde. Im Unterschied zur klassischen Lebensphilosophie und zu den an sie anknüpfenden ethischen Entwürfen wird das Leben bei Schopenhauer aber nicht als Zweck betrachtet, sondern als Mittel zu einem anderen Zweck, nämlich für die Ethik, die in der Verneinung des Willens zum Leben gipfelt. Schon in den frühesten handschriftlichen Aufzeichnungen verwendet Schopenhauer verschiedene Metaphern, um das Leben als Medium der ethischen Erkenntnis zu charakterisieren. Besonders häufig tritt dabei das Bild vom Leben als Spiegel auf, in dem der Mensch sein eigenes Wesen und damit auch das Wesen der Welt erblickt. Im Hauptwerk wird dann dieses Bild vom Begriff der Objektivation des Willens abgelöst. Insofern die höchste und deutlichste Objektivation des Willens der Lebenslauf des menschlichen Individuums darstellt, ist Schopenhauers Lebensbegriff eng mit seiner Charakterlehre verknüpft. In dem Beitrag wird das verwickelte Verhältnis von Leben, Erkennen und Ethik vor dem Hintergrund der proto-hermeneutischen Metaphysikkonzeption Schopenhauers anhand der Entwicklung der Spiegelmetapher betrachtet.

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.

Development of a test system for the determination of biodegradability in surface waters; Entwicklung eines Testsystems fuer die Pruefung des biologischen Abbaus in Oberflaechengewaessern

The study presented here describes the development of a laboratory test system for the determination of aerobic biodegradability of substances at low concentrations in surface water. It was aimed to prepare a draft guideline for a biodegradation simulation test according to OECD format. The experimental approach was based on a literature study conducted within the frame of this project. Further useful information on the possible test design was derived from the German BBA guideline 5-1. Natural water and sediments were collected. Radiolabelled Lindane or 4-Nitrophenol was added. The test vessels (reactors) were aerated and incubated under controlled conditions for up to 92 days. The results showed biological stability of the sediment/water systems even without addition of nutrients and adherence to non-reducing conditions. Mineralisation of 4-Nitrophenol was influenced by the sediment type, the method of aeration and temperature. Factors affecting the mineralisation of Lindane were the method of application and again, the sediment type and temperature. Considerable amounts of the radioactivity were bound to the sediment and were to a large extent unextractable. The potential of a reactor to mineralise a test substance could not be correlated with the biological parameters measured. (orig.)

F(R Gravity’s Rainbow and Its Einstein Counterpart

Directory of Open Access Journals (Sweden)

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.

Cosmology of Horava-Lifshitz f(R) gravity

We discuss the cosmology of recently proposed Horava-Lifshitz f(R) gravity. In particular, we derive the modified Hubble equation that reduces to the standard HL gravity case in appropriate limit. 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.)

The SINUS project intended to support building availability by regular maintenance, to reduce environmental pollution and waste production during the building life, to save natural resources, and to draw up a practical manual for this purpose. the findings were supported by tests on pilot plants and selected reference systems. [German] Primaeres Ziel des SINUS Projektes war es, die umweltgerechte Herstellung von nutzerorientierter Verfuegbarkeit von Gebaeuden durch eine nachhaltige Instandhaltung zu unterstuetzen, Umweltbelastungen waehrend der Betriebs-/Gebrauchsphase zu reduzieren, Stoffstroeme zu verringern, natuerliche Ressourcen zu schonen und die Ergebnisse in einem Handbuch des 'Integrierten Gebaeudeinstandhaltung und Umweltschutz Management Systems' abzubilden (siehe Schlussbericht Kapitel 2). Um die Praxistauglichkeit der Forschungsergebnisse zu gewaehrleisten, wurden diese staendig durch die Umsetzung an Pilotanlagen und ausgewaehlten Referenzsystemen evaluiert (siehe Schlussbericht Kapitel 5.3, 5.5). Es konnte einerseits detailliert dargelegt werden, dass sich erhebliche Synergieeffekte bei der Integration von Instandhaltung und Umweltschutz erzielen lassen (siehe Schlussbericht Kapitel 4,5). Andererseits wurde deutlich, dass Instandhaltung an sich angewandter Umweltschutz ist. Es wurden Methoden, Werkzeuge und systematische Vorgehensweisen entwickelt, die nachweislich nicht nur zu einer Verringerung des Material- und Energieverbrauches in einzelnen Phasen des Lebenszyklus fuehren, sondern vor allem zur Nachhaltigkeit der Nutzung, insbesondere zur Lebensdauerverlaengerung von Gebaeuden bzw. zur Nutzungsdauerverlaengerung einzelner Elemente des technischen Sachsystems Gebaeude, angewendet werden koennen. Ferner wurde deutlich, wie relevant die Einbindung des Know-how der operativen Ebene der Instandhaltung und des Umweltschutzes in verschiedene Lebenszyklusphasen (z.B.

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

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

The Federal Environmental Office views sustainable energy supply - of which the heat market is a decisive element - mostly under the aspect of climate protection and emission reduction of climate-relevant gases. If the heat market is to make a contribution here, the heat supply system must be reorganized. This publication of the Federal Environmental Office indicates fields of action in the heat market. The focus is on climate-friendly heat production, e.g. renewable energy sources, cogeneration systems, and higher energy efficiency.

Closed string tachyon driving f(R) cosmology

Science.gov (United States)

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.

2009-01-01

Full Text Available The development of international rivers is often perceived as leading to conflicts or even water wars. However, as the development of the Mekong River shows, cooperation has not only prevailed in the last decades, but River Basin Organizations (RBOs, established to mitigate river-related conflicts and/or develop the river basin, have also contributed to the emergence of more general cooperation structures, mainly by creating spill-over effects in other issue-areas, bringing cooperation to policy fields beyond the river itself. This article assesses the contribution of the Mekong River Commission (MRC and the Greater Mekong Sub-Region (GMS to the sustainable development of the Mekong Region as well as to the promotion of regional cooperation in mainland South-East Asia in general. --- Die Entwicklung grenzüberschreitender Flüsse wird oft mit Konflikten oder gar Kriegen um Wasser assoziiert. Wie jedoch die Entwicklung im Mekong-Becken zeigt, waren die vergangenen Jahrzehnte nicht nur von Kooperation gezeichnet, sondern Flussbeckenorganisationen konnten außerdem dazu beitragen, weitreichendere Kooperationsstrukturen zu entwickeln, die sich auf andere Politikfelder ausdehnen. Dieser Artikel beschäftigt sich mit dem Beitrag der Mekong River Commission (MRC und der Greater Mekong Sub-Region (GMS zur nachhaltigen Entwicklung in der Mekong Region sowie zur Förderung allgemeiner regionaler Kooperation im Festländischen Südostasien.

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.)

Binneberg, A.; Spoerl, G.; Buschmann, H.

1997-03-01

In the context of the research project, work was done for HTSL-SQUID on (1) the development of a thermo-siphon cooler (low fault and continuously working) and (2) the development of a latent storage cooler (low fault and discontinuously working). Two development versions of the latent storage cooler were followed up, the development of a spherical latent storage cooler and the development of an annular vessel latent storage cooler. A further precondition for the construction of the cooler was the use of split Stirling refrigerators as units producing the cold. The experimental sample was built up with refrigerators which could produce a nominal cooling output of 1.2 W at 80 K. Two samples of the thermo-siphon cooler were built, tested and improved. The second sample was developed further as a demonstration model, introduced at meetings and prepared for testing the cooling of HTSL-SQUIDs. The thermo-siphon cooler can be designed for cooling output up to about 2 W at 80 K and can be used controlled for a temperature range of 90 K to 66 K. (orig./MM) [Deutsch] Im Rahmen des Forschungsvorhabens wurde fuer HTSL-SQUID`s an der (1) Entwicklung eines Thermosiphon-Kuehlers (stoerarm und kontinuierlich arbeitend) und (2) Entwicklung eines Latentspeicher-Kuehlers (stoerfrei und diskontinuierlich arbeitend) gearbeitet. Bei dem Latentspeicher-Kuehler wurden zwei Entwicklungsversionen verfolgt, und zwar Entwicklung eines Kugel-Latentspeicher-Kuehlers und Entwicklung eines Ringgefaess-Latentspeicher-Kuehlers. Eine weitere Praemisse zum Aufbau der Kuehler war der Einsatz von Split-Stirling-Kaeltemaschinen als kaelteerzeugende Baugruppe. Die Versuchsmuster wurden mit Kaeltemaschinen aufgebaut, die eine Nennkuehlleistung von 1,2 W bei 80 K erzeugen konnten. Der Thermosiphon-Kuehler wurde in zwei Musterexemplaren aufgebaut, erprobt und verbessert. Das Zweitmuster wurde als Demonstrator weiterentwickelt, zu Fachtagungen vorgestellt und zur Testung der Kuehlung von HTSL

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.

Einen Ausweg aus dieser Problematik verspricht die Elektromechanische Bremsanlage (EMB) mit rueckwirkungsfreier Entkopplung des Fahrers von den Radbremsen (Brake-by-Wire). Das Bremskommando des Fahrers wird bei Betaetigung des Bremspedals rein sensorisch erfasst.

Disentangling the f(R). Duality

International Nuclear Information System (INIS)

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

2014-11-01

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

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

International Nuclear Information System (INIS)

Saaidi, Kh; Aghamohammadi, A

2012-01-01

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

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

International Nuclear Information System (INIS)

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

2009-01-01

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

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

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

International Nuclear Information System (INIS)

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

2010-01-01

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

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

The coincidence problem in holographic f(R) gravity

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

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

Science.gov (United States)

Lee, Seokcheon

2018-06-01

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

Herbert Fröhlich a physicist ahead of his time

CERN Document Server

Hyland, G J

2015-01-01

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

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

Directory of Open Access Journals (Sweden)

Barun Majumder

2013-01-01

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

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.

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

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

Generation of spherically symmetric metrics in f(R) gravity

Energy Technology Data Exchange (ETDEWEB)

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

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

Probing the f(R) formalism through gravitational wave polarizations

International Nuclear Information System (INIS)

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

2009-01-01

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

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

Reduction of environmental impact by FR cycle deployment

2005-03-01

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

FR4-based electromagnetic energy harvester for wireless sensor nodes

Science.gov (United States)

Hatipoglu, G.; Ürey, H.

2010-01-01

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

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)

2017-07-15

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.)

Der Wissenschaftshistoriker und Physiker Jürgen Renn untersucht die Rolle des österreichischen Physikers und Philosophen Ludwig Boltzmann (18441906) bei der Entwicklung der modernen Physik. Boltzmann war einer der letzen Vertreter des mechanistischen Weltbildes und stand somit am Ende eines Zeitalters. Renn porträtiert den Wissenschaftler aber als einen Pionier der modernen Physik, dessen Beschäftigung mit den inneren Spannungen der klassischen Physik ihn visionär zukünftige Fragestellungen aufgreifen ließ. So befasste sich Boltzmann etwa mit den Grenzproblemen zwischen Mechanik und Thermodynamik, die ihn zur Entwicklung immer raffinierterer Instrumente der statistischen Physik antrieb, die schließlich zu Schlüsselinstrumenten der modernen Physik wurden. Boltzmanns Werk steht somit am Übergang vom mechanistischen Weltbild zur Relativitäts- und Quantentheorie. Der Aussage des viel bekannteren Physikers Albert Einstein, dass Fantasie wichtiger sei als Wissen, hält Jürgen Renn im Hinblick auf Leben ...

Entwicklung von Landnutzungsszenarien für landschaftsökologische Fragestellungen

Science.gov (United States)

Fritsch, Uta

2002-04-01

Die Landschaften Mitteleuropas sind das Resultat einer langwierigen Geschichte menschlicher Landnutzung mit ihren unterschiedlichen, z.T. konkurrierenden Nutzungsansprüchen. Durch eine überwiegend intensive Beanspruchung haben die direkten und indirekten Auswirkungen der Landnutzung in vielen Fällen zu Umweltproblemen geführt. Die Disziplin der Landschaftsökologie hat es sich zur Aufgabe gemacht, Konzepte für eine nachhaltige Nutzung der Landschaft zu entwickeln. Eine wichtige Fragestellung stellt dabei die Abschätzung der möglichen Folgen von Landnutzungsänderungen dar. Für die Analyse der relevanten Prozesse in der Landschaft werden häufig mathematische Modelle eingesetzt, welche es erlauben die Landschaft unter aktuellen Verhältnissen oder hinsichtlich veränderter Rahmenbedingungen zu untersuchen. Die hypothetische Änderung der Landnutzung, die als Landnutzungsszenario bezeichnet wird, verkörpert eine wesentliche Modifikation der Rahmenbedingungen, weil Landnutzung mageblich Einfluss auf die natürlichen Prozesse der Landschaft nimmt. Während die Antriebskräfte einer solchen Änderung überwiegend von sozio-ökonomischen und politischen Entscheidungen gesteuert werden, orientiert sich die exakte Verortung der Landnutzungsänderungen an den naturräumlichen Bedingungen und folgt z.T. erkennbaren Regeln. Anhand dieser Vorgaben ist es möglich, räumlich explizite Landnutzungsszenarien zu entwickeln, die als Eingangsdaten für die Modellierung verschiedener landschaftsökologischer Fragestellungen wie z.B. für die Untersuchung des Einflusses der Landnutzung auf den Wasserhaushalt, die Erosionsgefahr oder die Habitatqualität dienen können. Im Rahmen dieser Dissertation wurde das rasterbasierte deterministische Allokationsmodell luck (Land Use Change Scenario Kit) für die explizite Verortung der Landnutzungsänderungen entwickelt. Es basiert auf den in der Landschaftsökologie üblichen räumlichen Daten wie Landnutzung, Boden sowie Topographie

Keys to evaluating and comparing FR fabric

Energy Technology Data Exchange (ETDEWEB)

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

2008-07-15

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

Fischverzehr in der Schwangerschaft: Risiko oder Benefit?

Directory of Open Access Journals (Sweden)

Gundacker C

2014-01-01

Full Text Available Fisch ist ein hochqualitatives Nahrungsmittel. Es enthält große Mengen an essenziellen Nährstoffen wie hochwertige Proteine, Vitamine, Jod, Selen und Omega-3-Fettsäuren, deren gesundheitsfördernde Wirkungen auf Gehirnentwicklung, intrauterines Wachstum und Gestationsdauer gut beschrieben sind. Gleichzeitig kann Fisch erhebliche Mengen an Schadstoffen beinhalten, insbesondere auch die organische Quecksilberverbindung Methyl-Quecksilber (Methyl-Hg. Das fetale Nervensystem ist besonders empfindlich gegenüber Belastung mit neurotoxischen Substanzen wie Methyl-Hg. Eine signifikante Beeinträchtigung der neurologischen Entwicklung von Kindern durch erhöhte pränatale Belastung ist belegt. Ergebnisse anderer Studien legen nahe, dass die mit dem Fischverzehr aufgenommenen essenziellen Nährstoffe solche Schadwirkungen kompensieren könnten. Insgesamt lässt die rezente Literatur keine eindeutige Aussage zu, ob der Fischverzehr in der Schwangerschaft ein Risiko oder einen Benefit für die fetale Entwicklung darstellt. Dies liegt daran, dass bislang nur wenige Studien die mit dem Fischverzehr einhergehende Aufnahme von essenziellen Nährstoffen und Schadstoffen in Relation zur Entwicklung von Kindern untersucht haben. Die Risiko-Benefit-Balance hängt zudem maßgeblich von individuellen Fischverzehrsgewohnheiten und damit von der jeweiligen Nährstoff-/Schadstoff-Zusammensetzung des konsumierten Fisches ab. Während der Schwangerschaft sollte nicht auf das hochwertige Nahrungsmittel Fisch verzichtet werden. Empfohlen wird ein Verzehr solcher Fische und Meeresfrüchte, die einen hohen Omega-3-Fettsäuregehalt und minimale Quecksilberbelastung aufweisen. Schwangere Frauen sollten über Risiken und Benefits des Fischverzehrs im Sinne der Gesundheitsförderung aufgeklärt werden.

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

Science.gov (United States)

Zhu, Jie; Pearce, Stephen; Burke, Adrienne; See, Deven Robert; Skinner, Daniel Z; Dubcovsky, Jorge; Garland-Campbell, Kimberly

2014-05-01

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

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

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

Development of new heterogeneous catalysts for the decomposition of methanol into hydrogen and carbon monoxide applying high throughput methods; Entwicklung neuer heterogener Katalysatoren zur Spaltung von Methanol in Wasserstoff und Kohlenmonoxid mittels Hochdurchsatz-Methoden

Energy Technology Data Exchange (ETDEWEB)

Weiss, Torsten

2008-07-11

The topic of this thesis has been the development of new heterogeneous catalysts for the decomposition of methanol into hydrogen and carbon monoxide. As an important constraint here, the content of noble metals of the catalysts should be as low as possible. High-throughput-methods were applied in some of the syntheses and experiments to accelerate the development, as, for example, the use of liquid based sol-gel syntheses and the examination of catalyst libraries by spatial resolution gas chromatography. This screening technique allowed to test up to 207 different substances during one single experiment. Then, different combinatorial strategies were applied. First, these methods led to a highly active and stable catalyst in the ternary system of Cu-Ni-Zn, which showed high conversion and selectivity comparable to an industrial reference catalyst. Its activity during an 18 hour long term run was constant in contrast to the reference. Second, an additional approach starting from a broader variety of elements led to a Ce- Ru- and to a Cr-Ru-catalyst. Both of them were highly active in short term experiments, but lost their outstanding performances during long term runs. (orig.) [German] Die vorliegende Arbeit befasste sich mit der Entwicklung neuer heterogener Katalysatoren fuer die Spaltung von Methanol zu Wasserstoff und Kohlenmonoxid, die einen moeglichst geringen Gehalt an Edelmetallen aufweisen sollten. Um diesen Prozess zu beschleunigen, wurden in einem Teil der Synthesen und Experimente Hochdurchsatzmethoden verwendet. Neben der Roboter gestuetzten Sol-Gel-Synthese umfasste dies die Untersuchung von Katalysatorbibliotheken mittels ortsaufgeloester Gaschromatographie, die es ermoeglichte, in einem Experiment bis zu 207 verschiedene Substanzen auf ihre katalytische Aktivitaet zu testen. Unter Anwendung verschiedener kombinatorischer Strategien wurde zunaechst ein sehr aktiver und stabiler Katalysator im ternaeren Cu-Ni-Zn-System entdeckt. Neben Umsaetzen und

Untersuchungen zur Entwicklung von Satellitengalaxien

Science.gov (United States)

Seidel, Björn

2002-01-01

Gleichgewichtsmodelle ein- und zweikomponentiger Satellitengalaxien werden erzeugt und die Gezeiteneinwirkungen der als starres äußeres Potential angenommenen Milchstraße auf sie betrachtet. Eine erste Reihe von Simulationen mit anfänglich kugelsymmetrischen einkomponentigen Satelliten zeigt, daß sich nach elliptischer Deformation ein Balken und Schweife ungleicher Länge ausbilden, deren Aussehen sich periodisch ändert. Mithilfe von Vergleichssimulationen wurden folgende Phänomene am Satelliten entdeckt: (1) Hochdichtebereiche in den Schweifen, (2) Niedrigdichtebereiche um den Kern bzw. Balken und (3) ein oft verdeckter Balken. Analysiert wird das Erscheinungsbild in Zeitabhängigkeit. Die Teilchen gehen dem Kern über den Balken verloren und bewegen sich entlang gewisser stets gleich aussehender charakteristischer Strukturen in die Schweife. Nach einer Herleitung allgemeiner Größen des mehrkomponentigen Kingprofils werden drei stabile Standardmodelle zweikomponentiger Satellitengalaxien mit Massenverhältnis 1:10 (baryonische zu dunkle Materie) und unterschiedlicher Verteilung der dunklen und sichtbaren Materie gefunden. Ohne die Allgemeinheit der Ergebnisse zu beeinträchtigen, wurde dabei die Große Magellanische Wolke als Grundlage der Modelle genommen. Nach geeigneter Wahl der Bahn, zu der der Gezeitenradius des verwendeten dreikomponentigen Milchstraßenpotentials sowohl analytisch als auch numerisch berechnet wird, werden Simulationen der Modelle analysiert. Hauptaugenmerk ist das unterschiedliche Verhalten der Komponenten. Hauptergebnisse: (1) Es ist möglich, große Anteile dunkler, jedoch nur geringe sichtbarer Materie abzulösen. Dunkle und sichtbare Materie können unterschiedliche morphologische Strukturen bilden. (2) Je nach Konzentration der Komponenten ist die Eigengravitation der Teilchen mehr oder weniger für das Aussehen bestimmend. (3) Die Kernauflösung des Satelliten findet im Perigalaktikum (PG), sein Zerfall aber erst im Apogalaktikum statt. (4) Die Geschwindigkeitsdispersionen der Komponenten im Kern sind im PG entlang der Sichtlinie kurzzeitig stark erhöht, sie fallen ebenso wie die Dichten und deren Verhältnis mit jedem PG stufenförmig ab; einiges davon sind nur Projektionseffekte. (5) Der radiale Verlauf der Geschwindigkeitsdispersion ist vom Bahnort abhängig er wurde genau untersucht. (6) Der Satellit zerfällt über einen Kreislauf aus Massenverlust, flacher werdendem Potential und kleiner werdendem Gezeitenradius. Equilibrium models of one- and two-component satellite galaxies are created. The tidal influence of the Milky Way, which is modeled as a rigid external potential, is examined. A first set of simulations adopting originally spherically-symmetric, one-component satellites show that after elliptical deformation, a bar and tails of unequal length arise which change their morphology cyclically. By considering comparative simulations, the following phenomena are discovered: (1) High-density regions in the tails, (2) low-density zones around the core or bar, (3) an often concealed bar. The overall morphology as function of time is analysed. The particles are lost from the core via the bar and move along certain morphologically characteristic structures into the tails. After deducing general quantities of the multi-component King model, three stable standard models of two-component satellite galaxies with different distributions of dark and visible matter are found. These models have a mass ratio of 1:10 for baryonic to dark matter. Without restriction to the universality of the results, the Large Magellanic Cloud was taken as basic prototype for these models. To choose the proper orbits, the tidal radius of the three-component model of the potential of the Galaxy is calculated both analytically and numerically. Then the simulations are analysed with the different behaviour of the components being the main focus of interest. Main results: (1) It is possible to detach a large fraction of dark matter but only a small amount of visible matter. Dark and visible matter may form different morphological structures. (2) Depending on the concentrations of the components, self-gravity may be the decisive factor for determining the morphology. (3) The dissolution of the core of the satellite occurs at perigalacticon (PG), but it does not decay before apogalacticon. (4) At PG the core densities of the components, their ratio and the velocity dispersions fall off in steps, the velocity dispersions along the line of sight show a high narrow peak. Some of these effects are just projection effects. (5) The radial dependence of the velocity dispersion is dependent on the orbital position; it is analysed in detail. (6) The satellite decays through a cycle of mass loss, an increasingly shallow potential and decreasing tidal radius.

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

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)

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.

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

zunehmend wahrgenommen, wobei bestimmte Gebietstypen wie altindustrialisierte Raeume, Bergbau- und Konversionsgebiete im Focus der Aufmerksamkeit stehen. Haeufig - so auch im ehemaligen Uranbergbaugebiet um Johanngeorgenstadt im saechsischen Erzgebirge - treten zu den Umweltschaeden allgemeine Probleme strukturschwacher Raeume (schwache wirtschaftliche Wertschoepfung, schlechte Erreichbarkeit). Durch die Selbstverstaerkung negativer Prozesse wird die Abwanderung der Bevoelkerung ausgeloest und die Siedlungen beginnen zu schrumpfen. Einzelfallbezogene und rein technische Loesungsansaetze, wie sie durch die regionale Strukturpolitik in der Vergangenheit praktiziert worden sind, geraten in derartigen Problemraeumen rasch an ihre Grenzen. Gefragt sind stattdessen komplexe Loesungen, die gezielt Einzelprojekte mit der Entwicklung neuer Perspektiven fuer die betroffenen Gemeinden verbinden. In Anbetracht der positiven Erfahrungen im Sanierungs- und Entwicklungsgebiet Uranbergbau wird jenen Bundeslaendern, in denen es Gebiete mit gravierenden Umweltschaeden gibt, empfohlen, Sanierungs- und Entwicklungsgebiete in die landes- und regionalplanerische Praxis zu uebernehmen. Dabei steht der Gedanke im Mittelpunkt, dass zunaechst die Ausweisung von Problemgebieten in Raumordnungsplaenen erfolgt und daraufhin Aktionsraeume gebildet werden, in denen Sanierungs- und Entwicklungsziele formuliert und umgesetzt werden.

This paper presents the major therapeutic uses of Fomes fomentarius (L. : Fr.) Fr., tinder polypore. The context of this fungus is a wooly and soft material so called amadou (tinder). During the XVIII and XIXth centuries, the fungal material was used as haemostatic dressing and bandage to keep the temperature and compress parts of the body. It was also used as cautery for moxibustion and was reported in several traditional pharmacopoeias (Hungarian, Chinese, Indian).

Brane f(R) gravity and the dark side of the universe

International Nuclear Information System (INIS)

Borzou, A.; Sepangi, H. R.; Shahidi, S.; Yousefi, R.

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 main topics of this thesis are the development and characterization of La/B{sub 4}C multilayer systems. For this these materials were evaluated and characterized for the applied electron-beam evaporation. For the monitoring of the evaporation process two separate in-situ layer thicknesses were available. For periodic multilayer systems the X-ray reflectometry used for Mo/Si multilayers was accepted. Because of the change from Mo/Si on La/B{sub 4}C the driving of the evaporation process had to be material-conditionedly further developed and optimized. For the fabrication of aperiodic La/B{sub 4}C multilayer systems additionally an in-situ ellipsometer was taken into operation. Furthermore a decreasement of the interface roughnesses and by this following increasement of the reflectivities of La/B{sub 4}C multilayers by polishing of the single layers with accelerated ions during the fabrication shall be studied. The fabricated multilayers are characterized and evaluated concerning roughnesses, reflectivities, ans spectral band width. [German] Im Mittelpunkt dieser Arbeit stehen die Entwicklung und Charakterisierung von La/B{sub 4}C-Multischichtsystemen. Dazu wurden diese Materialien fuer die verwendete Elektronenstrahlverdampfung evaluiert und charakterisiert. Fuer die Ueberwachung des Aufdampfprozesses standen zwei separate In-situ Schichtdickenkontrollen zur Verfuegung. Fuer periodische Multischichtsysteme wurde die fuer Mo/Si-Multischichten genutzte Roentgenreflektometrie uebernommen. Aufgrund des Wechsels von Mo/Si auf La/B{sub 4}C musste materialbedingt die Steuerung des Verdampfungsprozesses weiterentwickelt und optimiert werden. Fuer die Herstellung aperiodischer La/B{sub 4}C-Multischichtsysteme wurde zusaetzlich ein In-situ Ellipsometer in Betrieb genommen. Des Weiteren soll eine Senkung der Grenzflaechenrauigkeiten und damit einhergehende Erhoehung der Reflektivitaeten von La/B{sub 4}C-Multischichten durch das Polieren mit beschleunigten Ionen der

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.)

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.

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

The supply of certain substrates for biogas production is partly controversial discussed: 'Tank-or-plate' discussions, maize cultivation of the landscape and so forth. The research project 'Potential study for the sustainable production and supply of gaseous, renewable energy in Germany (Biogas Atlas)' examines the potentials of biogas production under consideration of various sustainability factors.
