  2. [Publication rate of Deutsche Forschungsgemeinschaft (DFG)-supported research projects. An analysis of the "fate" of DFG-support methods in anesthesia, surgery and internal medicine].

    Science.gov (United States)

    Boldt, J; Maleck, W

    2000-09-22

    Outstanding medical research is not possible without financial support. The success of supported research projects have been evaluated only rarely. The publication rate of research projects supported by the German Research Council (Deutsche Forschungsgemeinschaft [DFG]) was assessed separately for internal medicine, surgery, and anesthesiology. Based on the "Figures and Facts" published by the DFG all supported projects of 1996 for all three specialities were included. In a Medline-based analysis all published papers dealing with the supported project and all papers published by the supported persons from 1996 to may 2000 were documented. A total of 315 grants were analysed (internal medicine: 234; surgery: 63; anesthesiology: 18). Projects with clinical topics were less often supported (n = 80) than experimental projects (n = 235). 162 (69.3%) of the grants in internal medicine, 41 (65.1) in surgery, and 14 (77.8%) of the grants in anesthesiology were published. In anesthesiology all published projects were in English language (internal medicine: 98.2%; surgery: 95%). Independent of the topic of the grant, several supported persons in internal medicine and surgery did not publish any papers between 1996 and may 2000, whereas all supported anesthesiologists published papers in peer reviewed journals in this time period. The publication rate of DFG supported projects is not sufficient. Except for a final internal report after finishing the research project no quality control exists for DFG grants. Unfortunately, not all supported projects were published. A better feedback between the financial support by the DFG and the publication rate of DFG grants is desirable.

    1998-12-31

    Applied geology is employed in mining geology, raw materials geology, engineering geology, and hydrogeology, of which the two last-mentioned are the most important for the Department of Applied Geology. This series of publications arose from the need of making research findings, dissertations, theses and conference papers accessible to the public faster and more comprehensively than in national and international journals. [Deutsch] Die Aufgaben der angewandten Geologie sind im weitesten Sinne in der Montangeologie, in der Rohstoffgeologie, in der Ingenieurgeologie und in der Hydrogeologie zu sehen. Der engere Aufgabenbereich der Institute fuer Angewandte Geologie konzentriert sich der heutigen Fragestellung entsprechend meist auf die Ingenieurgeologie und Hydrogeologie. Wenn wir daraus noch die Umweltgeologie ableiten, so ist der Lehr- und Forschungsschwerpunkt auch des Karlsruher Lehrstuhles fuer Angewandte Geologie (AGK=Angewandte Geologie Karlsruhe) umrissen. Die vorliegende Schriftenreihe ist aus der Notwendigkeit entstanden, Forschungsergebnisse, Dissertationen und ausgewaehlte Diplomarbeiten sowie Beitraege einschlaegiger Tagungen in Karlsruhe rascher und u.U. umfangreicher als in internationalen oder nationalen Journalen moeglich zu publizieren.

    Regulation and the prevention of danger are among the main characteristics of the modern state. However, the idea and the conceptualization of what danger is have changed over time. The genealogy of these changes shows that the history of social change and the history of knowledge are well connected. The 1970s marked the start of a social transformation of Western industrialized societies. This article proposes that this transformation was connected with basic epistemic reconfigurations and that the genealogy of risk played a significant role. This thesis is explored through the example of DFG advisory politics. Beginning in the 1960s, the DFG expert commissions that had been established to make policy and regulation recommendations began to focus more and more on the health effects of environmental pollution. The Commission for Questions of Mutagenicity played a particularly interesting role because its recommendations resulted in the foundation of a research institution run by the DFG, the Central Laboratory for Mutagenicity Testing (CML). The challenges faced by the CML in mutagenic research and testing effected a crisis of the expert-based advisory politics of the Mutagenicity Commission and a fundamental shift in the way scientific (regulatory) knowledge was perceived and valued politically. The pattern of this crisis calls to mind the constellation of the "risk society", but as will be shown, the (re)balancing of science and politics/society presented here is more adequately understood within the framework of political epistemology.

    2018-01-01

    Presents an obituary for Morton Deutsch, who died March 13, 2017, at 97 years old. Deutsch believed in the power of ideas to rectify serious social problems, and in the role of science to refine our understanding of those ideas. Ranked among the 100 most eminent psychologists of the 20th century, he was a distinguished theorist and pioneer in the study of cooperation, conflict resolution and social justice, as well as a remarkably warm, wise and respectful mentor. Deutsch held numerous leadership positions, including faculty positions at Teachers College, Columbia University and New York University and various presidencies, and accumulated dozens of awards, including eight lifetime achievement awards and the creation of four awards in his name. He also trained as a psychoanalyst and had a private practice for many years. In 1986, he founded the International Center for Cooperation and Conflict Resolution at Columbia, where he continued to work and welcome students well into his 90s.

  19. Powering FITL for Deutsche Telekom

    Energy Technology Data Exchange (ETDEWEB)

    Schulz, W. [T-Nova Deutsche Telekom Innovationsgesellschaft mbH Technologiezentrum (Germany)

    2000-07-01

    Deutsche Telekom introduced the project OPAL (optical access line) 8 years ago. The development of new applications for FITL (FTTH, FTTB, FTTC) leads to new challenges for power systems. For the establishment of an optical fibre infrastructure at the subscriber line level a wide variety of possible optical fibre network topologies can be imagined. Different powering architectures must be developed including remote or local powering. This paper presents results and performances of the powering configurations to feed the optical network units (ONU) and remote OLT. Compared to conventional powering the centralised powering with remote feeding supply was implemented to power the ONU in the field economically. (orig.)

    1996-01-01

    With its 1995 annual report, the Deutsches Atomforum renders account of its activities to its members and the public. As is demonstrated, there has been light and shadow in 1995. It is stated with satisfaction that German nuclear power stations for another year have fulfilled their task of supplying power reliably and safely. With their share of one third in public power generation, they represent an important pillar of supply. A cause for concern is that fact that a basic energy-political consensus between the major political forces on the long-term role to be played in power supply by nuclear power generation continues to be lacking.

    1982-01-01

    In May 1982, the Deutsche Kernreaktor-Versicherungsgemeinschaft (German Nuclear Reactor Insurance Pool, DKVG), a pool of 111 insurance companies authorized to do business in the Federal Republic of Germany, had been engaged in the nuclear insurance business successfully for twenty-five years. DKVG is mainly engaged in the re-insurance against damage arising from nuclear power and fires, including the costs of decontamination and cleaning of plants used to split nuclear fuels and facilities and inventories, including the source materials and fuels of such facilities, and against legal third party liability arising from the operation of nuclear facilities, including the storage and disposal of waste and plant components turned radioactive. DKVG can reinsure abroad the risks it covers and, in turn, offer re-insurance of risks insured by foreign nuclear insurance pools. The largest damage to be covered also by DKVG to this day has been the property damage arising from the March 28, 1979 accident at the TMI-2 nuclear power station in the United States. The main problem faced by the nuclear plant insurance business in the Federal Republic of Germany, as in some other countries, is an increase in coverage capacity over a medium term. (orig.) [de

    Vagt, J; Distl, O

    2018-01-01

    This study investigated familial relationships among Deutsch Drahthaar dogs with craniomandibular osteopathy and examined the most likely mode of inheritance. Sixteen Deutsch Drahthaar dogs with craniomandibular osteopathy were diagnosed using clinical findings, radiography or computed tomography. All 16 dogs with craniomandibular osteopathy had one common ancestor. Complex segregation analyses rejected models explaining the segregation of craniomandibular osteopathy through random environmental variation, monogenic inheritance or an additive sex effect. Polygenic and mixed major gene models sufficiently explained the segregation of craniomandibular osteopathy in the pedigree analysis and offered the most likely hypotheses. The SLC37A2:c.1332C>T variant was not found in a sample of Deutsch Drahthaar dogs with craniomandibular osteopathy, nor in healthy controls. Craniomandibular osteopathy is an inherited condition in Deutsch Drahthaar dogs and the inheritance seems to be more complex than a simple Mendelian model. Copyright © 2017 Elsevier Ltd.

    Recently, secure quantum key distribution based on Deutsch's algorithm using the Bell state is reported (Nagata and Nakamura, Int. J. Theor. Phys. doi: 10.1007/s10773-017-3352-4, 2017). Our aim is of extending the result to a multipartite system. In this paper, we propose a highly speedy key distribution protocol. We present sequre quantum key distribution based on a special Deutsch-Jozsa algorithm using Greenberger-Horne-Zeilinger states. Bob has promised to use a function f which is of one of two kinds; either the value of f( x) is constant for all values of x, or else the value of f( x) is balanced, that is, equal to 1 for exactly half of the possible x, and 0 for the other half. Here, we introduce an additional condition to the function when it is balanced. Our quantum key distribution overcomes a classical counterpart by a factor O(2 N ).

  12. Realization of Deutsch-like algorithm using ensemble computing

    2003-01-01

    The Deutsch-like algorithm [Phys. Rev. A. 63 (2001) 034101] distinguishes between even and odd query functions using fewer function calls than its possible classical counterpart in a two-qubit system. But the similar method cannot be applied to a multi-qubit system. We propose a new approach for solving Deutsch-like problem using ensemble computing. The proposed algorithm needs an ancillary qubit and can be easily extended to multi-qubit system with one query. Our ensemble algorithm beginning with a easily-prepared initial state has three main steps. The classifications of the functions can be obtained directly from the spectra of the ancilla qubit. We also demonstrate the new algorithm in a four-qubit molecular system using nuclear magnetic resonance (NMR). One hydrogen and three carbons are selected as the four qubits, and one of carbons is ancilla qubit. We choice two unitary transformations, corresponding to two functions (one odd function and one even function), to validate the ensemble algorithm. The results show that our experiment is successfully and our ensemble algorithm for solving the Deutsch-like problem is virtual

    We generalize the Deutsch-Jozsa algorithm by exploiting summations of the roots of unity. The generalized algorithm distinguishes a wider class of functions promised to be either constant or many to one and onto an evenly spaced range. As previously, the generalized quantum algorithm solves this problem using a single functional evaluation. We also consider the problem of distinguishing constant and evenly balanced functions and present a quantum algorithm for this problem that does not require any initialization of an auxiliary register involved in the process of functional evaluation and after solving the problem recovers the initial state of an auxiliary register.

    It has always been a tradition at the Winter Meeting of the Deutsches Atomforum to review the status of nuclear power in the world, in Europe and, of course, in Germany. On the global and European scenes, nuclear power is experiencing an upswing, while it continues to be blocked in Germany. Given the pressing issues of climate protection, continuity of energy supply, and the prices of energy resources, the future of nuclear power can well be seen in an optimistic light. The EU Commission recognizes the potential of nuclear power for a sustainable energy mix; the mood of the German public is shifting; and even media known for their critical attitude to nuclear power are now clamoring for an unbiased discussion of the issue. The ideological ban on thinking is waning. There will be a reassessment of nuclear power also in Germany because of the realities to be faced. If you really want to protect the climate, you cannot exclude the nuclear power option. After all, this is not a matter of confrontation designed to divide society; such times are past and gone for nuclear power. There is need for a factual dialog. We extend a sincere invitation to join in this dialog, and we want to contribute to it. After all, this is the true purpose of the Deutsches Atomforum, to which all of us feel committed. (orig.)

  20. Unifying parameter estimation and the Deutsch-Jozsa algorithm for continuous variables

    2010-01-01

    We reveal a close relationship between quantum metrology and the Deutsch-Jozsa algorithm on continuous-variable quantum systems. We develop a general procedure, characterized by two parameters, that unifies parameter estimation and the Deutsch-Jozsa algorithm. Depending on which parameter we keep constant, the procedure implements either the parameter-estimation protocol or the Deutsch-Jozsa algorithm. The parameter-estimation part of the procedure attains the Heisenberg limit and is therefore optimal. Due to the use of approximate normalizable continuous-variable eigenstates, the Deutsch-Jozsa algorithm is probabilistic. The procedure estimates a value of an unknown parameter and solves the Deutsch-Jozsa problem without the use of any entanglement.

    Full Text Available Tsunamis symbolize one of the most harmful natural disasters for low-lying coastal zones and their residents, due to both its destructive power and irregularity. The 2004 Boxing Day tsunami, which attack the Andaman Sea coast of Thailand, resulted 5,395 of deaths and inestimable casualties, interrupted economies and social well-being in numerous coastal villages and caused in extreme alterations of both onshore and offshore coastal morphology. The Great Indian Ocean tsunami also highlighted that there are many missing jigsaw puzzle pieces in scientific knowledge, starting from the generating of tsunamis offshore to the countless influences to the marine ecosystems on the continental shelf, coastal areas and on land and to the economic and social systems consequences. As with all deposits that do not have a direct physical link to their causative sources, marine tsunami deposits must be distinguished from other deposits through regional correlation, dating and criteria for recognition within the deposits themselves. This study aims to provide comprehensive reviews on using Polycyclic Aromatic Hydrocarbons (PAHs as a chemical proxy to discriminate tsunami relateddeposits from typical marine sediments. The advantages and disadvantages of this chemical tracer will be critically reviewed and further discussed.

In these gates, the entanglement of randomly placed electron spin qubits is manipulated by optical excitation of control electrons. The circuit we describe solves the Deutsch problem with an improved algorithm called the refined Deutsch-Jozsa algorithm. We show that it is possible to select optical pulses that solve the Deutsch problem correctly, and do so without losing quantum information to the control electrons, even though the gate parameters vary substantially from one gate to another

    Even if the installed electrical power of the hydraulic power plant Bad Abbach (Federal Republic of Germany) of Deutsche Bahn AG with only 4,500 kVA is quite modest, a significant planning effort was necessary due to numerous boundary conditions. The construction of this unusual hydraulic power plant signified a very demanding and interesting technical challenge for all concerned. The already existing damming of the river Danube required very little interventions in the environment. Thus the hydraulic power plant satisfied all the requirements also in environmental regard. Due to the cooperation of a Kaplan turbine shaft with a single-phase AC generator for supplying power to the Deutsche Bahn AG and due to the direct supply of electrical energy into the overhead wire system of the railroad, the new hydropower plant Bad Abbach is unique. With Deutsche Bahn AG as a consumer of energy from hydropower plants inter alia on the river Danube a partnership between the Rhein Main Donau AG (Munich, Federal Republic of Germany) and E.ON Wasserkraft GmbH (Landshut, Federal Republic of Germany) was continued in the field of renewable energies.

  16. Efficient classical simulation of the Deutsch-Jozsa and Simon's algorithms

    Johansson, Niklas; Larsson, Jan-Åke

    2017-09-01

    A long-standing aim of quantum information research is to understand what gives quantum computers their advantage. This requires separating problems that need genuinely quantum resources from those for which classical resources are enough. Two examples of quantum speed-up are the Deutsch-Jozsa and Simon's problem, both efficiently solvable on a quantum Turing machine, and both believed to lack efficient classical solutions. Here we present a framework that can simulate both quantum algorithms efficiently, solving the Deutsch-Jozsa problem with probability 1 using only one oracle query, and Simon's problem using linearly many oracle queries, just as expected of an ideal quantum computer. The presented simulation framework is in turn efficiently simulatable in a classical probabilistic Turing machine. This shows that the Deutsch-Jozsa and Simon's problem do not require any genuinely quantum resources, and that the quantum algorithms show no speed-up when compared with their corresponding classical simulation. Finally, this gives insight into what properties are needed in the two algorithms and calls for further study of oracle separation between quantum and classical computation.

    On the basis of the experience acquired with the environmental audit at RAG the internal audit was extended by the safety at work and health protection fields. This approach is the logical adaptation to the development of the integrated management system in labour, health and environmental protection (LHE), which is specified in the internal RAG LHE concept. The audit serves essentially for regular and systematic checking of the management process in labour, health and environmental protection. The aims pursued with this integrated audit and also the course of an audit are explained. In addition the special requirements both on an audit in a mining company and also on own auditors are outlined. This internal check has been carried out in all RAG Deutsche Steinkohle companies since 2008. (orig.)

Das bedeutet, dass die deutschen Unternehmen nicht weiter mit der Verwirklichung politischer Zielvorstellungen belastet werden. Die deutsche Energiewirtschaft braucht Chancengleichheit mit den europaeischen Mitbewerbern. So sollten sich auch die europaeischen Partnerlaender nicht auf die Mindestbedingungen der Binnenmarkt-Richtlinie zur Marktoeffnung beschraenken. Zweitens muss die deutsche Energiepolitik im Interesse von inlaendischer Beschaeftigung und Wertschoepfung angesichts des erheblich gewachsenen Wettbwerbsdrucks neue Formen der Kooperation mit der Energiewirtschaft entwickeln. Auch die Zielkonflikte zwischen Nachhaltigkeit, Versorgungssicherheit und Wirtschaftlichkeit muessen nicht nur moderiert, sondern produktiv aufgeloest werden. Drittens bedeutet dies: Keine unzumutbare Loesung in Sachen Kernenergie. Wer die deutsche Energiewirtschaft im Interesse der heimischen Arbeitsplaetze und Zukunftschancen in ihrer Staerke erhalten will, kann nicht in Kauf nehmen, dass die deutsche Energiewirtschaft zusaetzliche Marktanteile im Inland an andere europaeische Unternehmen verliert. Viertens brauchen wir eine neue Energiepolitik, die rational und weniger emotional die Ergebnisse des Marktes zur Kenntnis nimmt. Sie sollte sich in diesem Zusammenhang kuenftig auf die marktgerechte Foerderung von erneuerbaren Energien und Technologien zur Steigerung der Energieeffizienz beschraenken. Fuenftens darf die deutsche Energiepolitik jetzt nicht den Fehler

    Full text: As part of the preliminary works for the hydropower project Hainburg on the Danube, comprehensive geological, geophysical, hydrogeological, hydrological, hydrochemical and radiohydrometrical investigations were carried out. Special attention was paid to the area of Bad Deutsch Altenburg since questions of connections between Danube water, groundwater and the sulphur-medicinal springs of Bad Deutsch Altenburg and karst waters had to be settled. Long term observations and the data from series of analysed water samples led to the following conclusions: (1) The thermal deep groundwater, the autochthonous karst water, the shallow groundwater and the Danube belong to a common system with hydraulic interactions. (2) The discharge of the thermal mineral waters in Bad Deutsch Altenburg is caused by a NW-SE striking fault zone. (3) The thermal mineral waters are overburdened by the karst waters in the area Kirchenberg and Pfaffenberg. At the contact zone mixing occurs. Owing to changing pressure conditions and to the locally different conductivity of the karst aquifer the discharges of mineral waters differ in concentration and temperature. (4) The water level of the thermal mineral waterbody is 1 to 2 m above the water level of the Danube at low flow. This difference is equalized at the Danube water level above 141.5 m a.s.l. Above the mark 142 m a.s.l. a direct influence of the observation wells situated in the Park was observed. (5) Because the Danube has eroded the karst massif (Mesozoic limestones and dolomites, Leitha limestone) down to a depth of about 132-133 m a.s.l. the level of karst water drainage was deeper than today. Currently the area is covered by highly permeable gravels. (6) It is therefore assumed that a considerable amount of thermal water drains directly into the Danube. Recharge and mixing with the shallow groundwater was proved. (7) The considerable discharge implies a catchment which extends beyond the immediate environment. (author)

    We present an optical scheme to implement the Deutsch-Jozsa algorithm using ac Stark shifts. The scheme uses an atomic ensemble consisting of four-level atoms interacting dispersively with a field. This leads to a Hamiltonian in the atom-field basis which is quite suitable for quantum computation. We show how one can implement the algorithm by performing proper one- and two-qubit operations. We emphasize that in our model the decoherence is expected to be minimal due to our usage of atomic ground states and freely propagating photon

    Total nuclear power generation in Germany in 1999 sums up to 169.7 billion kWh and thus almost equals the all-time high of the operating year 1997, which was at 170.4 billion kWh. Power generation in nuclear power plants has been contributing well a third of the total domestic power supply since 1988, which is about ten per cent of the national power consumption. This is one aspect of the information contained in the annual report of Deutsches Atomforum e.V. Expressing this 1999 output in terms of carbon dioxide emissions avoided, the figure is 170 million tonnes. This is equal to the annual CO2 emissions in 1999 emanating from road transport and traffic in Germany. From the very beginning of nuclear power generation in 1961 until today, aggregated nuclear power generation from uranium and plutonium fuels amounts to about 2.8 billion kWh, which means that over this period, more than two billion tonnes of carbon dioxide emissions have been avoided.

    A general framework for regarding oracle-assisted quantum algorithms as tools for discriminating among unitary transformations is described. This framework is applied to the Deutsch-Jozsa problem and all possible quantum algorithms which solve the problem with certainty using oracle unitaries in a particular form are derived. It is also used to show that any quantum algorithm that solves the Deutsch-Jozsa problem starting with a quantum system in a particular class of initial, thermal equilibrium-based states of the type encountered in solution-state NMR can only succeed with greater probability than a classical algorithm when the problem size n exceeds ∼10 5 .

    Full Text Available This article uses the case of the Deutsch-Asiatische Bank and its liquidation during the First World War to examine the challenges faced by German businesses during the war in China and China’s involvement in Allied economic warfare. This case suggests the detrimental effect that political crises and global shifts of power had on foreign businesses in modern China’s globalized treaty port economy. It also reveals China’s role in the global economic warfare of the Allies, showing that China first resisted Allied demands for a full liquidation of the German bank but eventually acquiesced to Allied pressure and handed control over the liquidation to the Allies. As a consequence, China ended up violating the very international law it had put so much value on when entering the war.

    2010-06-01

    One of the longstanding attractions of the Deutsches Museum in Munich, Germany, has been its display of the apparatus associated with the discovery of nuclear fission. Although the discovery involved three scientists, Otto Hahn, Lise Meitner, and Fritz Strassmann, the fission display was designated for over 30 years as the Arbeitstisch von Otto Hahn (Otto Hahn’s Worktable), with Strassmann mentioned peripherally and Meitner not at all, and it was not until the early 1990s that the display was revised to include all three codiscoverers more equitably. I examine the creation of the fission display in the context of the postwar German culture of silencing the National Socialist past, and trace the eventual transformation of the display into a contemporary exhibit that more accurately represents the scientific history of the fission discovery.

    The study examines the nature, conditions, and outcomes of student learning from an organised guided tour in the Deutsches Museum in Munich. The instructional methods that best support students' cognitive and affective learning as well as how students' motivational and emotional states influence their achievement were investigated. A sample of 96 secondary school students took part in two different versions of a guided tour on an energy topic. The tours varied in the degree of support of students' active involvement, group work, and the variety of general activities offered during the tour. The data collected indicate that both tour versions led to an increase in student understanding of the visit topic to nearly the same extent. However, the version stimulating students' active participation, group work, and including a larger variety of activities aroused more positive attitudes. Students of the modified school programme showed higher interest and intrinsic motivation, felt more competent, and were less bored after the guided tour. In addition, the results suggest that students' visit-related emotional states predict the degree of their post-visit topic understanding, even when demographics and prior knowledge are taken into consideration.

    Wilke, Jürgen

    Nach anfänglichen Schwierigkeiten durch den 1. Weltkrieg erlangte die Deutsche Statistische Gesellschaft (DStatG) unter dem renommierten Statistiker und Vorsitzenden der DStatG, Friedrich Zahn, durch eine Vielzahl von Aktivitäten hohes Ansehen. Es gab Bestrebungen, Statistiker aus allen Arbeitsfeldern der Statistik in die DStatG zu integrieren, wobei die "Mathematische Statistik" nur zögerlich akzeptiert wurde (Konjunkturforschung, Zeitreihenanalyse). Nach der Machtübernahme 1933 durch Adolf Hitler geriet die DStatG in das Fahrwasser nationalsozialistischer Ideologie und Politik (Führerprinzip, Gleichschaltung des Vereinswesens). Damit war eine personelle Umstrukturierung in der DStatG verbunden. Politisch Missliebige und rassisch Verfolgte mussten die DStatG verlassen (Bernstein, Freudenberg, Gumbel u.a.). Unter den Statistikern gab es alle Abstufungen im Verhalten zum Regime von Ablehnung und zwangsweiser Anpassung über bereitwilliges Mitläufertum bis zu bewusster Täterschaft. Besonders die Bevölkerungsstatistik wurde durch die NS- Rassenpolitik auf lange Sicht diskreditiert. Im Rahmen von Wirtschaftsplanung und Aufrüstung wurden neue zukunftsträchtige statistische Modelle (Grünig, Bramstedt, Leisse) entwickelt.

    Part A introduces the German national bibliographical data bank BIBLIO-DATA is based on the Information-Retrieval-System STAIRS from IBM which was improved by additional programs of ZMD. The primary emphases of this article is on the discussion of the BIBLIO-DATA concept according to which the data of 'Deutsche Bibliographie' are being prepared and stored suitable for information retrieval. BIBLIO-DATA is based on national bibliographical data, the characteristics, problems and deficiencies due to this fact are mentioned very detailed. Two additional comments show the various possibilities of research with BIBLIO-DATA by means of some examples in order to show that the research work is not only faster but also much more effective. Part B proves that BIBLIO-DATA cannot automate the analysis of contents or the allocation of subject heading. At the present state of operation BIBLIO-DATA has to support the conventional-intellectual work of subject cataloguing by retrospective research especially because of the considerably facilitated access to former indexing results. Part C describes the practical work with BIBLIO-DATA concerning bibliographical research and literature compilation and comes to the conclusion that effective bibliographical work is based on an appropriate combination of data-bank retrieval and conventional research work.

  3. Deutsch, Toffoli, and cnot Gates via Rydberg Blockade of Neutral Atoms

    2018-05-01

    Universal quantum gates and quantum error correction (QEC) lie at the heart of quantum-information science. Large-scale quantum computing depends on a universal set of quantum gates, in which some gates may be easily carried out, while others are restricted to certain physical systems. There is a unique three-qubit quantum gate called the Deutsch gate [D (θ )], from which a circuit can be constructed so that any feasible quantum computing is attainable. We design an easily realizable D (θ ) by using the Rydberg blockade of neutral atoms, where θ can be tuned to any value in [0 ,π ] by adjusting the strengths of external control fields. Using similar protocols, we further show that both the Toffoli and controlled-not gates can be achieved with only three laser pulses. The Toffoli gate, being universal for classical reversible computing, is also useful for QEC, which plays an important role in quantum communication and fault-tolerant quantum computation. The possibility and speed of realizing these gates shed light on the study of quantum information with neutral atoms.

    The memory effects in non-Markovian quantum dynamics can induce the revival of quantum coherence, which is believed to provide important physical resources for quantum information processing (QIP). However, no real quantum algorithms have been demonstrated with the help of such memory effects. Here, we experimentally implemented a non-Markovianity-assisted high-fidelity refined Deutsch-Jozsa algorithm (RDJA) with a solid spin in diamond. The memory effects can induce pronounced non-monotonic variations in the RDJA results, which were confirmed to follow a non-Markovian quantum process by measuring the non-Markovianity of the spin system. By applying the memory effects as physical resources with the assistance of dynamical decoupling, the probability of success of RDJA was elevated above 97% in the open quantum system. This study not only demonstrates that the non-Markovianity is an important physical resource but also presents a feasible way to employ this physical resource. It will stimulate the application of the memory effects in non-Markovian quantum dynamics to improve the performance of practical QIP.

    To enhance the quality of tool steels it is necessary to analyse all stages of the production process. During the ingot- or continuous casting processes and the following solidification, material and geometry depending reactions cause defects such as macro segregations or porosities. In former times the trial and error approach, together with the experience and creativity of the steelworks engineers was used to improve the as-cast quality, with a high amount of test procedures and a high demand of research time and costs. Further development in software and algorithms has allowed modern simulation techniques to find their way into industrial steel production and casting-simulations are widely used to achieve an accurate prediction of the ingot quality. To improve the as-cast quality, several ingot casting processes of tool steels were studied at the R and D department of Deutsche Edelstahlwerke GmbH by using the numerical casting simulation software MAGMASOFT ® . In this paper some results extracted from the simulation software are shown and compared to experimental investigations.

    2011-05-01

    Full Text Available This article discusses one deliberative approach to dialogue as conceptualized by the philosopher Jürgen Habermas and brings this into a conversation with the current dialogue practice of the Deutsche Islam Konferenz (DIK in Germany. This ongoing dialogue forum was initiated by the Ministry of the Interior in the autumn of 2006 in order to enact a structured conversation with Muslims and as a means of recognising them as ‘German Muslims’. My main argument is twofold. Focusing on Habermas’s ideal of dialogue as a consensus oriented rational discourse of equal citizens in non-hegemonic structures, I will argue, on the one hand, that much of the promise of the DIK to enact a dialogue with Muslims at eyelevel and to recognise them as equal citizens on the basis of the liberal-democratic order has not been fulfilled. With its top-down approach to Muslims as mere re-actors the DIK has so far turned out to be much more a governmental technique which aims at reshaping Muslims according to liberal/secular norms. On the other hand, I claim that although the DIK obviously runs counter to Habermas’s principles in many ways, it also shares and simultaneously lays bare the difficulties entailed in his consensus orientation, and, more importantly, in the secular bias of his approach.Schirin Amir-Moazai is Assistant Professor for Islam in Europe in the Department of Islamic Studies at Free University Berlin.

  18. The metaphysics of D-CTCs: On the underlying assumptions of Deutsch's quantum solution to the paradoxes of time travel

    Science.gov (United States)

    Dunlap, Lucas

    2016-11-01

    I argue that Deutsch's model for the behavior of systems traveling around closed timelike curves (CTCs) relies implicitly on a substantive metaphysical assumption. Deutsch is employing a version of quantum theory with a significantly supplemented ontology of parallel existent worlds, which differ in kind from the many worlds of the Everett interpretation. Standard Everett does not support the existence of multiple identical copies of the world, which the D-CTC model requires. This has been obscured because he often refers to the branching structure of Everett as a "multiverse", and describes quantum interference by reference to parallel interacting definite worlds. But he admits that this is only an approximation to Everett. The D-CTC model, however, relies crucially on the existence of a multiverse of parallel interacting worlds. Since his model is supplemented by structures that go significantly beyond quantum theory, and play an ineliminable role in its predictions and explanations, it does not represent a quantum solution to the paradoxes of time travel.

    2002-01-01

    The 2002 Winter Meeting organized by the Deutsches Atomforum e.V. was devoted to the topic of 'Energy Supply in the 21st Century - the Role of Nuclear Power'. Before a large audience of participants from Germany and abroad experts from science and research, industry and politics discussed a broad range of problems arising with respect to the future national, European, and global structure of energy supply. The new impulses nuclear power is receiving in the United States and in Finland were presented along with the contributions potentially coming from non-nuclear sources of energy, including the importance of renewable energies. The conclusion to be drawn from all contributions is the recognition that boundary conditions and constraints demand a balanced energy mix, which can be achieved only in a liberal environment free from any political or ideological discrimination.

    Full Text Available  O trabalho inscreve-se no campo da história da educação no Rio Grande do Sul e analisa uma dimensão da imigração alemã para este Estado no início do século 20. Trata-se de mapear concepções de professor e de professora produzidas/ reproduzidas pelo jornal Deutsche Post, no período de 1906 a 1915, buscando apreender com isso, de forma mais ampla, os sentidos atribuídos à escola elementar teuto-brasileira, enquanto instância de produção e de preservação do germanismo e do luteranismo nas regiões de colonização. Fundamenta-se no pressuposto de que os jornais e almanaques teuto-brasileiros constituem importantes recursos de conservação da língua alemã nas comunidades e, mais do que isso, são importantes elementos de fortalecimento da Igreja e da escola, apresentadas neles como os pilares da preservação cultural.Palavras chave: produção cultural, concepções de professor, escola elementar teuto-brasileira.   Abstract This work is inserted in the field of the history of the education in Rio Grande do Sul and analyses a dimension of the germany immigration to the state in the 20lh century. It is about building concepts of male and female teachers produced and reproduced by the "Deutsche Post" Journal, from 1906 to 1915, aiming to learn with this, in a more large aspect, the concepts conferred to the german-brasilian elementary school as a place to produce and preserve the german culture and the protestantism in colonization areas. It is based on the principle that german-brasilian newspapers and almanacs are important means of preserving the german language among communities. More than this, german-brasilian almanacs and newspapers are fundamental elements to strengthen the church and the school, which are considered pillars in the preservation of culture. Keywords: production of culture, concepts of teacher, german-brasilian elementary school.

Autologous Fat Grafting is a long established treatment in plastic surgery and does not differ from other tissue grafts. 2. Mechanical processing of autologous fat does not provide any substantial change tot he tissue. 3. If other treatment methods to enrich progenitor cells of autolous fat i. e. by an enzymatic process have evidence that autologous adipose tissue or cells were substantially changed, classification as a drug could come in question under current german law (application of AMG/ATMP). © Georg Thieme Verlag KG Stuttgart · New York.

    The political upheaval in Germany in 1933 and subsequent movement of medical scholars with the support of the Rockefeller Foundation allowed Manchester to benefit from the arrival of Dr Walter Deutsch, later known as Dr Walter Dale. His research background enabled him to develop a radiobiochemistry laboratory at the Christie Hospital and Holt Radium Institute where he became a world authority on the effects of X-rays on enzymes and also the protective effect of additional solutes. In 1959 he initiated and then edited the International Journal of Radiation Biology. By the time of his retirement in 1962 the strength of his research resulted in his laboratory being recognized by the Medical Research Council.

    2015-05-01

    Full Text Available Schlinks Erzählung stellt anhand zweier Liebender das Scheitern eines deutsch-jüdischen Gesprächs dar und verhandelt die Frage, wie viele Differenzen eine Beziehung aushält. Die titelgebende Beschneidung tritt dabei nicht nur auf der Handlungsebene auf, wo der Protagonist durch Konversion zum Judentum die Differenz zu seiner jüdischen Freundin zu überwinden hofft. Auch auf metaphorischer Ebene problematisiert die Erzählung die ›Selbstbeschneidung‹ des Protagonisten, der aus Angst vor Tadel von jüdischen Figuren viele seiner Gedanken nicht ausspricht. Als Opfer antideutscher Vorurteile ruft er diverse antisemitische Stereotype auf. Der Beitrag geht der Frage nach, inwiefern die Erzählung damit für solch stereotypes Gedankengut sensibilisiert und subtil gegen einen antisemitischen und revisionistischen Diskurs anschreibt oder inwiefern sich der Text vielmehr in einen solchen Diskurs einschreibt.

Its financial existence between the world wars was assured by generous donations from the Jewish American scholar and philanthropist James Loeb. The scientific work done by Walther Spielmeyer (neuropathology), Felix Plaut (serology), Kurt Schneider (clinical psychiatry) and Ernst Rudin (psychiatric genetics) earned the DFA a reputation as an international center for psychiatry and neurology. During the 'Third Reich' Ernst Rudin cooperated with the National Socialist health system. His genetic concepts provided support for eugenic programmes such as forced sterilization of individuals with psychoses. These complex interactions underscore the importance of the DFA in understanding the recent history of medicine in Germany.

    En este ensayo voy a contrastar la interpretación de Borges a la de un intelectual austríaco que fue testigo y víctima del régimen de Hitler, Wilhelm Reich. Reich escribió una temprana obra, desde su perspectiva de médico y psicoanalista, interpretando el fenómeno: La psicología de masas del fascismo, de 1934, que revisó y reescribió para la edición norteamericana, aparecida en 1946, el mismo año que Borges publicó «Deutsches Requiem» en la revista Sur.

    2015-04-01

    Full Text Available The economic crisis of the European Union has rendered the European public sphere as a forever emerging concept marked by uncertainties regarding its structure. In this context, eyes of both European officials and citizens turn towards the media, the main communication link between the EU and its citizens. The present paper looks at a media product that is designed to permeate multiple national public spheres, the weekly news show European Journal, a half-hour TV program produced by Deutsche Welle and rebroadcast by partner TV channels throughout Europe. Considering the main characteristics of the European public sphere as identified in the literature, with a focus on horizontal Europeanization, and using the method of content analysis, this paper looks at the means employed by the European Journal to support the integration process and to add a European dimension to national public sphere. Findings suggest that the type of public sphere promoted by the European Journal is not centered around the EU as a distinct entity, but around the member states, approach which supports the idea of a horizontal Europeanization.

    Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system.

    On 17th December 2008 the German Federal Cabinet adopted the German Strategy for Adaptation to Climate Change (DAS: Deutsche Anpassungsstrategie) (BUNDESREGIERUNG 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and foremost, the DAS contributes its guidelines at Federal level, to provide guidance for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in the process. The Strategy is divided into 13 action fields and two cross-sectional fields (=14+15). (1) Human health (2) Building sector (3) Water regime, water management, coastal and marine protection (4) Soil (5) Biological diversity (6) Agriculture (7) Woodland and forestry (8) Fishery (9) Energy industry (conversion, transport and supply) (10) Financial services industry (11) Transport, transport infrastructure (12) Trade and industry (13) Tourism industry (14) Spatial, regional and physical development planning (15) Civil protection. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and implement the DAS. This will be made available for download from www.anpassung.net. An integral part of this will be the 'Tatenbank' (www.tatenbank.anpassung.net), the 'Klimalotse' (www.klimalotse.anpassung.net), FISKA (special information system 'Adaptation') and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far as the Indicator System is concerned, it has been decided to prepare a Report on Indicators for the challenges facing Germany and the

    Directory of Open Access Journals (Sweden)

    2003-10-01

    Full Text Available Der vorliegende Beitrag beinhaltet die ersten Ergebnisse einer Langzeitstudie, bei der flächendeckend die deutsche Nachkriegsberichterstattung über Frankreich von 1946 bis 1970 inhaltsanalytisch ausgewertet wurde. Die Studie stützt sich dabei auf das Modell der Nachrichtenfaktoren von Johan Galtung, welche nach seiner Ansicht die Auswahl der Themen bestimmen, die zu einer Nachricht werden. Genau in diesen Selektionsroutinen liegt jedoch die implizite Gefahr, Konflikte zu vertiefen statt sie einzudämmen bzw. durch ein breites Verständnis der Hintergründe gewaltfrei bearbeitbar zu machen. Für die Zeit nach einem Krieg könnten sie Hindernisse auf dem Weg zur Annäherung und Aussöhnung ehemaliger Gegner darstellen. Wie jedoch sieht die Berichterstattung nach dem Krieg tatsächlich aus? Zeigen Massenmedien Bereitschaft zu einer veränderten Berichterstattung? Der Fall der französisch-deutschen Aussöhnung, welcher als Beispiel für einen gelungenen Aussöhnungsprozess gelten kann, belegt, dass Friedensprozesse von den Medien durchaus adäquat begleitet werden können: Z.B. ist der Anteil "positiver" Themen bzw. Berichterstattung konsistent höher als der "negativer", und der Anteil von Non-Elite-Themen steigt an und kündet von Interesse an französischer Lebensart und Kultur. Die Ergebnisse zeigen, dass Negativismus in den Medien kein Naturgesetz ist, sondern überwunden werden kann, wenn Frieden und Versöhnung auf der Tagesordnung stehen.

    Both fluoroketone C5F10O and fluoronitrile C4F7N are promising substitute gases for SF6. The electron-impact ionization cross sections for these two gases are calculated using the Deutsch-Märk (DM) formula and its modified method. The necessary molecular geometry optimization and electron population were determined by ab initio calculation, which was performed with quantum chemistry code. The level of calculation, including the theoretical method and basis-set, are carefully determined. To eliminate the drawbacks of the DM formula, a modified DM formula is set in this paper. The modified DM formula, of which the weighting factors are changed, has a better agreement with the experimental data on both the peak and shape of the cross-section curves. The results calculated by DM formula and modified DM formula are given as references to fill in gaps in further research into C5F10O and C4F7N.

    Full Text Available Este artículo aborda dos obras de escritores latinoamericanos que tienen como tema común el nazismo: “Deutsches Requiem” de Jorge Luis Borges y Morirás lejos de José Emilio Pacheco. Partiendo del problema de la representación del mal, estudiamos las diversas estrategias que estos autores proponen para abordarlo. En primer lugar, los modos de construir a los nazis Otto Dietrich y eme, es decir, de representar “seres absolutamente perversos”. Analizamos luego el empleo de las notas al pie, que contribuyen a multiplicar la instancia narrativa e introducir la autorreflexividad en obras que parecen requerir alguna forma de distanciamiento. Por último, abordamos la intertextualidad bíblica, indagando las funciones específicas que tiene en cada texto. Buscamos abrir perspectivas sobre un problema central para la literatura contemporánea —la escritura del mal— y estimular los estudios sobre las obras literarias latinoamericanas que abordan las Shoah, y que, consideramos, no han recibido suficiente atención de la crítica.

    The recurrent safety inspection is intended as an inspection supplementing the continuous operation monitoring activities within the framework given by the supervisory activities of the supervisory authority. The first recurrent safety inspection is scheduled to be performed about ten years after start-up of the plant, with subsequent inspection intervals to cover ten-year periods, and recorded operating and monitoring results to be taken into account at each recurrent inspection. The purpose of the recurrent safety inspections is to ascertain that post-inspection operation of the plant meets the then required safety standards. Significant testing results of the latest inspection are to be analysed and compared with regard to the current state of the art and operating results accumulated since the previous inspection, for subsequent definition of enhancements if required.

    Germany is dependent on imports for its metalliferous natural resources. Although prices have been declining significantly in recent months, numerous raw materials such as platinum, cobalt and rare earth elements continue to be exposed to price and supply risks. To ensure that German industry can respond better to this situation in their procurement activities, the German Mineral Resources Agency (DERA) at BGR has developed a raw material monitoring system on behalf of the German government. DERA experts have con figured a screening method for the early identification of possible procurement risks. This is the platform which enables German companies to gain the specific advice they require. All of the most important information on this issue is bundled within DERA 's internet portal (www.deutsche-rohstoffagentur.de). BGR also provides its expertise in other important fields with great societal relevance. BGR has been advising the national commission on ''Storage of High-level Radioactive Waste'' since 2014. Due to their comprehensive research activities in the field of radioactive waste disposal, BGR scientists are important technical experts to which the commission can turn to for geological information and advice.

    Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system. PMID:24771931

    There is an increasing awareness of using our energy resources more efficiently which also leads to the finding of the importance of energy-efficient building services and operation. Unfortunately, we often restrict ourselves looking only at the costs of the investment itself instead of taking into account also the costs during the long time of building. This proceeding discusses the energy potentials of building and industry automation and control and how the potentials can be calculated and increased in industry and manufacturing. Further more, energy efficiency as a task for coaching people to change behaviour is shown taking into account measures to met understanding for energy saving problems. (orig./GL)

    By two exemplary clinical situations — acute viral hepatitis, acute-phase reaction of the liver — the significance of basic research for the understanding of clinical phenomena and for the development of new diagnostic and therapeutic procedures is demonstrated. The very different phenomena following infection with the hepatitis-B-virus can be explained by the variation in the interactions of virus and liver cell, by the immune reaction of the host, and by mutants of the virus. The reaction of the liver to an extrahepatic infection is mediated by interleukin-6, and characterized by an alteration in protein metabolism. The synthesis of acute-phase proteins is increased. The proteins confine the local injury and establish the homeostasis of the organism.

    1976-01-01

    In the example of nuclear energy, the crisis of people in the modern industrial society is analysed by means of six themes: 1) the fear-envy syndrome; 2) the identity crisis; 3) projection and identification; 4) citizens initiatives; 5) information policies; 6) group aims. The author infers that in reality, almost too much information has already been given, it is already difficult for the recipient to still get a clear picture. In his opinion, it is not a question of deficit of information but rather a deficit of confidence. The ever more abstract and non-transparent industrial society combines to produce fear in people. This fear might have found a field af activity in citizens' initiatives to prevent nuclear power plant construction. Accordingly, it is necessary before anything, to develop a relationship of confidence between citizens' initiatives, nuclear power plant builders and operators as well as politicians. (HP) [de

Es basiert zum Teil auf einem in den USA in den 70iger Jahren entwickelten rein deterministischen Konzept. Die Materialkennkurve wird darin mit Hilfe der RTNDT (Referenztemperatur) indiziert, die mittels mechanisch-technologischer Versuche bestimmt wird. Der Vergleich mit den Bruchmechanikkennwerten zeigt, dass die KIc(T-RTNDT)-Kurve die experimentellen Daten einhuellt. Weltweit sind Bestrebungen im Gange, neben dem bewaehrten RTNDT-Konzept ein auf bruchmechanischen Kennwerten basierendes Konzept einzufuehren. Ein wesentlicher Vorteil des neuen Konzepts besteht darin, dass es eine direkte Ermittlung der Sproedbruchuebergangstemperatur aus bruchmechanischen Versuchen und damit eine realistischere Uebertragung auf das Bauteilverhalten ermoeglicht. Um die Einfuehrung des Master-Kurve-Konzeptes in die Integritaetsbewertung des RDB in Deutschland voranzubringen, sind noch eine Reihe von offenen Fragestellungen wie z.B. die Bezugnahme auf eine repraesentative Datenbasis fuer bestrahlte deutsche RDB-Werkstoffe und der Einfluss der Probenform- und groesse zu klaeren. Es besteht weiterhin die Notwendigkeit, das bestehende mit dem neuen Konzept zu vergleichen und die Frage zu klaeren, inwieweit Crack Arrest Kurven an bestrahltem Werkstoff erstellt werden koennen und wie sich Crack Arrest in das neue Sicherheitskonzept integrieren lasst.

In drawing on the experiences from more than three decades of social science research on this West African country, it refers to examples from the past and present of African Studies in Germany, as well as describing the potential for German–African cooperation in this field in the future. Aside from this, it raises the question of whether and how social science cooperation is possible given the economic and power disparities. It is argued that cooperation “on equal terms” will not be easy to achieve but must be consistently striven for – personally as well as politically.Dieser Bericht fasst die Beiträge und Debatten einer Konferenz zur deutsch-beninischen Kooperation in der Sozialforschung (Universität Bayreuth, 8.-10.

Gleichzeitig wird die Frage beleuchtet, ob und wie angesichts der vorhandenen wirtschaftlichen Unterschiede und hierarchischen Strukturen eine Kooperation in der sozialwissenschaftlichen Forschung möglich ist. Die Autorinnen halten eine Zusammenarbeit zu gleichen Bedingungen für schwer erreichbar, plädieren aber dafür, sich kontinuierlich dafür einzusetzen – persönlich und politisch.

    The author explains the reasons and motives for agricultural reclamation which is still necessary in the mining districts of 'the New Laender'. Reclamation has to be aimed at the general objectives of a sustainable land use. The procedures of reclamation have to consider the special site conditions on the dumps. First of all they serve for the development of soil fertility. Proceeding from the research on agricultural reclamation carried out before 1990 the need of research at the beginning of the BMBF priority programme 'Rehabilitation and reclamation of landscapes after lignite mining in the New Laender' and the gained knowledge are given dealing with the topics: use and amelioration of cohesive mine soils, cultivation of alternative crops and pasture usage in post mining landscapes as well as application of soil improvers out of organic waste materials. Finally current deficits of knowledge are pointed out. (orig.)

    Electric brake systems and components are increasing in importance due to the easy wheel-selective operation in future vehicle concepts. Building electric brake systems economically is decisively dependent on the availability of wheel brakes suitable in terms of dynamic behaviour, energy requirements, space, size, reliability and costs. In particular, the coupling of the transducer and friction brake by means of a suitable gear system adapted to the requirements of a vehicle brake represents a problem which has not yet been satisfactorily solved. In Subproject B6 of the Sonderforschungsbereich 241-IMES, sponsored by the Deutsche Forschungsgemeinschaft, research on new mechatronic brake systems is being conducted at the Automotive Engineering Department of Darmstadt University.

  8. Deutsche und albanische Phraseologismen mit Tierbezeichnungen im Kontrast

    Full Text Available The object of this article are animal idioms in contemporary German and Albanian: the article treats those units that denote animal names in their formal structure with phraseological, figurative meaning. The aim of the article is to identify and describe the differences and similarities between these two languages from the viewpoint of a contrastive analysis. The German phraseology has often been the subject of inter-linguistic comparisons. However, this can not be claimed for the German – Albanian language analysis. In this article, some similarities and differences in animal symbolism in the German and Albanian phraseology are illustrated by typical examples, and equivalence relations between the German and Albanian animal idioms are identified.It can be concluded that the animal names in idiom units indicate positive and negative characteristics or behavior of people. One result is that the negative semantic characteristics predominate in both languages. The animal name depends on a concrete idiom not only from the ideas and values that are attributed to an animal in a language community, but also from the already existing structures and pragmatic rules in a concrete language.

  15. Israelische Public Diplomacy und ihre Wahrnehmung durch deutsche Journalisten

    Directory of Open Access Journals (Sweden)

    Florian Fleischer

    2014-07-01

    Full Text Available Public Diplomacy stellt insbesondere für Staaten in internationalen Konflikten wie Israel ein wichtiges Kommunikationsinstrument dar, um ausländische Bevölkerungen zu erreichen. Der Artikel zeigt die Ergebnisse einer Studie, in der untersucht wurde, wie die israelische Public Diplomacy von deutschen Journalisten aufgenommen und verarbeitet wird. Journalisten kommt dabei eine Schlüsselrolle als Mittler zwischen dem israelischen Staat und der deutschen Bevölkerung zu. In Anlehnung an den Katalog der Public Diplomacy-Maßnahmen von Gilboa (2006 wurde die Relevanz einzelner Maßnahmen für Journalisten erfragt. Die Ergebnisse zeigen, dass persönliche Kontakte für Journalisten nach wie vor eine wichtige Quelle darstellen und nicht von Cyber-Public Diplomacy ersetzt werden können. Staatliche Public Diplomacy wird zwar wahrgenommen, jedoch wird ihre Objektivität bezweifelt, während NGOs und Stiftungen als vertrauenswürdiger eingestuft werden. Des Weiteren wird Israel in der Öffentlichkeit nach wie vor dominierend mit dem Nahostkonflikt identifiziert, was sich nach Meinung der befragten Journalisten auch in Zukunft nicht durch gezielte Öffentlichkeitsarbeit verhindern lässt.

  17. Cost accounting at the Deutsches Elektronen Synchrotron = DESY

    International Nuclear Information System (INIS)

    1979-01-01

    The cost accounting procedure, consisting of accountings of cost type, burden centers and over-all projects, makes available comprehensive information at regular intervals. This procedure assists in the acquisition of data concerning the costs of the individual projects, data which at the same time form the basis for determining internal services which can be activated or for the invoicing of outside contracts. In addition, the cost accounting can insure a detailed comparison of debits and assests, if corresponding standards are established for cost type, burden centers and over-all projects. The cost accounting print-outs, published quarterly, are put at the disposal of the project commission, among others, which oversees the handling of technical projects, from project application through the planning stage and execution until completion. Further evaluations are planned, in particular, concerning the introduction of company code numbers as well as the projection of cost accounting results into future planning considerations. (author)

  7. Deutsches Atomforum e.V. annual report 1989

    International Nuclear Information System (INIS)

    1990-01-01

    The German Nuclear Forum could see the first indications of a possible new trend in the evaluation of nuclear energy at the World Energy Conference in Montreal. It became evident there that the preservation of the earth's atmosphere will be the main challenge for environmental and energy policies in the next few decades and only with the aid of nuclear energy, not without or against it, can it be achieved. In the Federal Republic, too, opinion polls have shown that an absolute majority of our citizens do not want to abandon nuclear energy because they believe nuclear power stations to be necessary and not harmful to the environment. The abandonment of nuclear energy is no longer a pressing political problem, even for the SPD. The annual report gives, inter alia, the most important nuclear energy data for 1989 and the operational statistics of the nuclear power stations. It presents reports from the areas of technology and industry, publicity and press, law and administration, economy and industry, international cooperation, cooperation with other organizations and on the activities and the organization of the German Nuclear Forum.

    2016-03-01

    Vacuum birefringence is another lingering challenge which will soon become accessible to experimental verification. The effect was first calculated by Euler and Heisenberg in 1936 and is these days described as a one-loop correction to the differential index of refraction between light which is polarized parallel and perpendicular to an external magnetic field. Our plan is to realize (and slightly modify) an idea which was originally published by Hall, Ye, and Ma using advanced LIGO and LISA technology and the infrastructure of the ALPS light-shining-through-walls experiment following the ALPS IIc science run. This work is supported by the Deutsche Forschungsgemeinschaft and the Heising-Simons Foundation.

    Weiss, Stephan; Wei, Ping; Ahlers, Guenter

    2015-11-01

    Turbulent thermal convection under rotation shows a remarkable variety of different flow states. The Nusselt number (Nu) at slow rotation rates (expressed as the dimensionless inverse Rossby number 1/Ro), for example, is not a monotonic function of 1/Ro. Different 1/Ro-ranges can be observed with different slopes ∂Nu / ∂ (1 / Ro) . Some of these ranges are connected by sharp transitions where ∂Nu / ∂ (1 / Ro) changes discontinuously. We investigate different regimes in cylindrical samples of aspect ratio Γ = 1 by measuring temperatures at the sidewall of the sample for various Prandtl numbers in the range 3 Deutsche Forschungsgemeinschaft.

    The Excellence Initiative has not only been the most prominent funding scheme in German research policy in recent years, but has also had important side effects on research management. This paper argues that the Excellence Initiative was indeed a “boost” for improving the data infrastructure and statistical reporting of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation). The learning effects are now transferred to the line business and serve as a good starting point for the reporting on a potential third phase of the Excellence Initiative. (Author)

    Science.gov (United States)

    Finster, Felix; Reintjes, Moritz

    2009-05-01

    We set up the Dirac equation in a Friedmann-Robertson-Walker geometry and separate the spatial and time variables. In the case of a closed universe, the spatial dependence is solved explicitly, giving rise to a discrete set of solutions. We compute the probability integral and analyze a spacetime normalization integral. This analysis allows us to introduce the fermionic projector in a closed Friedmann-Robertson-Walker geometry and to specify its global normalization as well as its local form.

  18. Optimal spin current pattern for fast domain wall propagation in nanowires

    2011-03-01

    One of the important issues in nanomagnetism is to lower the current needed for a technologically useful domain wall (DW) propagation speed. Based on the modified Landau-Lifshitz-Gilbert (LLG) equation with both Slonczewski spin-transfer torque and the field-like torque, we derive an optimal temporally and spatially varying spin current pattern for fast DW propagation along nanowires. Under such conditions, the DW velocity in biaxial wires can be enhanced as much as tens of times higher than that achieved in experiments so far. Moreover, the fast variation of spin polarization can efficiently help DW depinning. Possible experimental realizations are discussed.

    2017-11-01

    We report experimental studies on turbulent vertical convection flow in the liquid metal alloy gallium-indium-tin. Flow measurements were conducted by a combined use of local Lorentz force velocimetry (LLFV) and ultrasound Doppler velocimetry (UDV). It is known that the forced convection flow in a duct generates a force on the LLFV magnet system, that grows proportional to the flow velocity. We show that for the slower flow of natural convection LLFV retains this linear dependence in the range of micronewtons. Furthermore experimental results on the scaling of heat and momentum transport with the thermal driving are presented. The results cover a range of Rayleigh numbers 3 ×105 Deutsche Forschungsgemeinschaft under Grant No. GRK 1567.

    The scaling theory of Grossmann and Lohse for the turbulent heat and momentum transfer is extended to the magnetoconvection case in the presence of a (strong) vertical magnetic field. The comparison with existing laboratory experiments and direct numerical simulations in the quasistatic limit allows to restrict the parameter space to very low Prandtl and magnetic Prandtl numbers and thus to reduce the number of unknown parameters in the model. Also included is the Chandrasekhar limit for which the outer magnetic induction field B is large enough such that convective motion is suppressed and heat is transported by diffusion. Our theory identifies four distinct regimes of magnetoconvection which are distinguished by the strength of the outer magnetic field and the level of turbulence in the flow, respectively.

  1. Transitional boundary layer in low-Prandtl-number convection at high Rayleigh number

    2016-11-01

    The boundary layer structure of the velocity and temperature fields in turbulent Rayleigh-Bénard flows in closed cylindrical cells of unit aspect ratio is revisited from a transitional and turbulent viscous boundary layer perspective. When the Rayleigh number is large enough the boundary layer dynamics at the bottom and top plates can be separated into an impact region of downwelling plumes, an ejection region of upwelling plumes and an interior region (away from side walls) that is dominated by a shear flow of varying orientation. This interior plate region is compared here to classical wall-bounded shear flows. The working fluid is liquid mercury or liquid gallium at a Prandtl number of Pr = 0 . 021 for a range of Rayleigh numbers of 3 ×105 Deutsche Forschungsgemeinschaft.

    Oxygen vacancies in oxide heterostructures create a plethora of electronic phenomena not observed in the stoichiometric systems. In this talk we will discuss the presence of a new type of in-gap states at the spinel/perovskite γ-Al2O3/SrTiO3 interface, as observed in soft x-ray resonant photoemission spectroscopy. Based on ab initio calculations and crystal-field analysis of different atomic environments, we identify the origin of this behavior and we argue on the possible origin of the extraordinarily high electron mobility measured in this heterostructure.

  3. On the radiometric measurement of the density distribution occuring at the horizontal hydraulic transport of solid matter

    1977-01-01

    In order to estimate the phenomena of the flow in horizontal hydraulic transport of solid matter, measuring the density structure along the vertical pipe diameter is of vital interest for basic investigations. The measurement technology in mixed flows of solid matter and water is very difficult and therefore only few publications on characteristic flow profiles in horizontal pipes are known. In a research programme advanced by the Deutsche Forschungsgemeinschaft investigations were made on the possibility to measure the density profile by means of plain measuring equipment based upon radiometrics. In this paper a combination of a nuclear radiometric polar and parallel scanning method is shown to be suitable for this kind of measurements. (orig.) [de

    Nucleon shell closures are generally associated with a local minimum in mean-square charge radii, 〈r2 〉 , along an isotopic chain. The 〈r2 〉 of 18Ar and 19K isotopes, however, do not show this signature at the N = 20 neutron shell closure. To gain a microscopic understanding of this abnormal behavior, measurements of 〈r2 〉 of neutron-deficient Ca isotopes below N = 20 have been proposed at the BEam COoling and LAser spectroscopy (BECOLA) facility at NSCL/MSU. Preliminary results will be presented and the deduced charge radii will be compared to theoretical calculations and the trends in the nearby isotopic chains.

    2017-11-01

    Large-scale patterns of the temperature and velocity field in horizontally extended cells can be considered as turbulent superstructures in Rayleigh-Bénard convection (RBC). These structures are obtained once the turbulent fluctuations are removed by a finite-time average. Their existence has been reported for example in Bailon-Cuba et al.. This large-scale order obeys a strong similarity with the well-studied patterns from the weakly nonlinear regime at lower Rayleigh number in RBC. In the present work we analyze the superstructures of RBC at different Prandtl number for Prandtl values between Pr = 0.005 for liquid sodium and 7 for water. The characteristic evolution time scales, the typical spatial extension of the rolls and the properties of the defects of the resulting superstructure patterns are analyzed. Data are obtained from well-resolved spectral element direct numerical simulations. The work is supported by the Priority Programme SPP 1881 of the Deutsche Forschungsgemeinschaft.

    Calcium is unique for its possession of two stable isotopes of ``doubly magic'' nuclei at proton and neutron numbers (Z , N) = (20 , 20) and (20 , 28) . Recent charge radii measurements of neutron-rich calcium isotopes yielded an upward trend beyond current theoretical predictions. At the BECOLA facility at NSCL/MSU, Ca charge radii measurements will be extended to the neutron-deficient regime using collinear laser spectroscopy. A new photon detection system with an ellipsoidal reflector and a compound parabolic concentrator has been commissioned for the experiment. The system increases the signal-to-noise ratio by reducing background, which is critical for the low production rates of the Ca experiment. Details of the system and results of the characterization tests will be discussed.

  7. Variationally optimal selection of slow coordinates and reaction coordinates in macromolecular systems

    Science.gov (United States)

    Noe, Frank

    To efficiently simulate and generate understanding from simulations of complex macromolecular systems, the concept of slow collective coordinates or reaction coordinates is of fundamental importance. Here we will introduce variational approaches to approximate the slow coordinates and the reaction coordinates between selected end-states given MD simulations of the macromolecular system and a (possibly large) basis set of candidate coordinates. We will then discuss how to select physically intuitive order paremeters that are good surrogates of this variationally optimal result. These result can be used in order to construct Markov state models or other models of the stationary and kinetics properties, in order to parametrize low-dimensional / coarse-grained model of the dynamics.

  8. Fluctuations of Wigner-type random matrices associated with symmetric spaces of class DIII and CI

    Science.gov (United States)

    Stolz, Michael

    2018-02-01

    Wigner-type randomizations of the tangent spaces of classical symmetric spaces can be thought of as ordinary Wigner matrices on which additional symmetries have been imposed. In particular, they fall within the scope of a framework, due to Schenker and Schulz-Baldes, for the study of fluctuations of Wigner matrices with additional dependencies among their entries. In this contribution, we complement the results of these authors by explicit calculations of the asymptotic covariances for symmetry classes DIII and CI and thus obtain explicit CLTs for these classes. On the technical level, the present work is an exercise in controlling the cumulative effect of systematically occurring sign factors in an involved sum of products by setting up a suitable combinatorial model for the summands. This aspect may be of independent interest. Research supported by Deutsche Forschungsgemeinschaft (DFG) via SFB 878.

    The dynamics of a bented dark soliton embedded in two spatial dimensions beyond the mean-field approximation is explored. We examine the case of a single bented dark soliton comparing the mean-field approximation to a correlated approach that involves multiple orbitals. Fragmentation is generally present and significantly affects the dynamics, especially in the case of stronger interparticle interactions and in that of lower atom numbers. It is shown that the presence of fragmentation allows for the appearance of solitonic and vortex structures in the higher-orbital dynamics. In particular, a variety of excitations including dark solitons in multiple orbitals and vortex-antidark complexes is observed to arise spontaneously within the beyond mean-field dynamics.

  10. Application of the DMRG in two dimensions: a parallel tempering algorithm

    Hu, Shijie; Zhao, Jize; Zhang, Xuefeng; Eggert, Sebastian

    The Density Matrix Renormalization Group (DMRG) is known to be a powerful algorithm for treating one-dimensional systems. When the DMRG is applied in two dimensions, however, the convergence becomes much less reliable and typically ''metastable states'' may appear, which are unfortunately quite robust even when keeping a very high number of DMRG states. To overcome this problem we have now successfully developed a parallel tempering DMRG algorithm. Similar to parallel tempering in quantum Monte Carlo, this algorithm allows the systematic switching of DMRG states between different model parameters, which is very efficient for solving convergence problems. Using this method we have figured out the phase diagram of the xxz model on the anisotropic triangular lattice which can be realized by hardcore bosons in optical lattices.

    Recent scanning tunneling spectroscopy measurements on the organic charge tranfer salt κ-(BEDT-TTF)2Cu[N(CN)2]Br show clear evidence of a highly anisotropic gap structure. Based on an ab initio derived model Hamiltonian we employ random phase approximation spin fluctuation theory yielding a composite order parameter of (extended) s+dx2-y2 symmetry. Taking explicitly also the shape of the Fermi surface into account we calculate STS spectra that are in excellent agreement to the experimental observations [1]. Moreover we determine the minimal tight binding model to describe the general lattice structure of these compounds accurately and generate a phase diagram for the gap symmetry by varying the hopping parameters. Based on ab initio derived parameter sets we predict the gap symmetry of other superconducting κ charge transfer salts.

    Full Text Available In Germany national licences are funded by the "Deutsche Forschungsgemeinschaft (DFG" as part of their system for nationwide literature supply. In contrast there is no comparable scheme and no central office to finance and foster research information infrastructure in Austria. Universities in Austria obviously suffer more and more from the lack of backfile archives particularly in the field of e-journals and literature databases. Out of this in 2007 the task force "ARGE Bibliotheksdirektor/-innen" started to pull the attention of university steering boards and political decision-makers towards this important topic which is critical for science and research in Austria.

  13. Active Mesogenic Droplets: Impact of Liquid Crystallinity and Collective Behavior

    Science.gov (United States)

    Bahr, Christian

    Droplets of common mesogenic compounds show a self-propelled motion when immersed in aqueous solutions containing ionic surfactants at concentrations well above the critical micelle concentration. After introducing some general properties of this type of artificial microswimmer, we focus on two topics: the influence of liquid crystallinity on the swimming behavior and the collective behavior of ensembles of a larger number of droplets. The mesogenic properties are not essential for the basic mechanism of self-propulsion, nevertheless they considerably influence the swimming behavior of the droplets. For instance, the shape of the trajectories strongly depends on whether the droplets are in the nematic or isotropic state. The droplet swimmers are also ideally suited for the study of collective behavior: Microfluidics enables the generation of large numbers of identical swimmers and we can tune their buoyancy. We report on the collective behavior in three-dimensional environments. Supported by the Deutsche Forschungsgemeinschaft (SPP 1726 ``Microswimmers'').

    Shishkina, Olga; Lohse, Detlef; Grossmann, Siegfried

    2017-11-01

    We analyse the boundary layer (BL) equations in natural thermal convection, which includes vertical convection (VC), where the fluid is confined between two differently heated vertical walls, horizontal convection (HC), where the fluid is heated at one part of the bottom plate and cooled at some other part, and Rayleigh-Benard convection (RBC). For BL dominated regimes we derive the scaling relations of the Nusselt and Reynolds numbers (Nu, Re) with the Rayleigh and Prandtl numbers (Ra, Pr). For VC the scaling relations are obtained directly from the BL equations, while for HC they are derived by applying the Grossmann-Lohse theory to the case of VC. In particular, for RBC with large Pr we derive Nu Pr0Ra1/3 and Re Pr-1Ra2/3. The work is supported by the Deutsche Forschungsgemeinschaft (DFG) under the Grant Sh 405/4 - Heisenberg fellowship.

    The THz range (1-12 THz, 30-400 cm-1) is especially suited to probe changes in the solvent dynamics induced by solutes of different character (hydrophobic, hydrophilic, charged, neutral). In recent years we have investigated a large variety of such solutes and found characteristic spectral fingerprints for ions, but also for uncharged solutes, such as alcohols. We will present a status report on our current understanding of the observed spectral changes and how they relate to physico-chemical parameters like hydration shell size or the lifetime of an excited intermolecular oscillation. In addition, we will show, that in some cases the spectral changes are closely related to the partition function yielding access to a microscopic understanding of macroscopic thermodynamic functions.

    Kruse, Karsten; Wollrab, Viktoria; Thiagarajan, Raghavan; Wald, Anne; Riveline, Daniel

    Networks of polymerizing actin filaments are known to be capable to self-organize into a variety of structures. For example, spontaneous actin polymerization waves have been observed in living cells in a number of circumstances, notably, in crawling neutrophils and slime molds. During later stages of cell division, they can also spontaneously form a contractile ring that will eventually cleave the cell into two daughter cells. We present a framework for describing networks of polymerizing actin filaments, where assembly is regulated by various proteins. It can also include the effects of molecular motors. We show that the molecular processes driven by these proteins can generate various structures that have been observed in contractile rings of fission yeast and mammalian cells. We discuss a possible functional role of each of these patterns.

    Electronic structure calculations within Hedin's GW approximation are becoming increasingly accessible to the community. In particular, as it has been shown earlier and we confirm by calculations using our MBPT_LCAO package, the computational cost of the so-called G0W0 can be made comparable to the cost of a regular Hartree-Fock calculation. In this work, we study the performance of our new implementation of G0W0 to reproduce the ionization potentials of all 117 closed-shell molecules belonging to the G2/97 test set, using a pseudo-potential starting point provided by the popular density-functional package SIESTA. Moreover, the ionization potentials and electron affinities of a set of 24 acceptor molecules are compared to experiment and to reference all-electron calculations.

    The non-equilibrium dynamics of small boson ensembles in one-dimensional optical lattices is explored upon a sudden quench of an additional harmonic trap from strong to weak confinement. We find that the competition between the initial localization and the repulsive interaction leads to a resonant response of the system for intermediate quench amplitudes, corresponding to avoided crossings in the many-body eigenspectrum with varying final trap frequency. In particular, we show that these avoided crossings can be utilized to prepare the system in a desired state. The dynamical response is shown to depend on both the interaction strength as well as the number of atoms manifesting the many-body nature of the tunneling dynamics.

The moments of the structure functions correspond with various polarizabilities, and I will explain why one of them - δLT - is especially interesting.

    2017-11-01

    The scaling of physical quantities that characterize the shape and dynamics of the viscous and thermal boundary layers with respect to the Rayleigh number will be presented for three series of three-dimensional high-resolution direct numerical simulations of Rayleigh-Benard convection (RBC) in a closed cylindrical cell of aspect ratio one. The simulations have been conducted for convection in air at a Prandtl number Pr = 0.7, in liquid gallium at Pr = 0.021 and in liquid sodium at Pr = 0.005. Then we discuss three statistical analysis methods which have been developed to predict the transition of turbulent RBC into the ultimate regime. The methods are based on the large-scale properties of the velocity profile. All three methods indicate that the range of critical Rayleigh numbers is shifted to smaller magnitudes as the Prandtl number becomes smaller.

    2017-04-01

    The usage of photons as long-range information carriers has greatly increased the interest in systems with nonlinear optical properties in recent years. The nonlinearity is easily achievable in Rydberg mediums through the strong van der Waals interaction which makes them one of the best candidates for such a system. Here, we propose a way to analyze the steady state solutions of a Rydberg medium in a cavity through the combination of the variational principle for open quantum systems and the P-distribution of the density matrix. To get a better understanding of the many-body-dynamics a transformation into the polariton picture is performed and investigated. Volkswagen Foundation, Deutsche Forschungsgemeinschaft.

  3. Topologically non-trivial electronic and magnetic states in doped copper Kagome lattices

    Guterding, Daniel; Jeschke, Harald O.; Valenti, Roser

    We present a theoretical investigation of doped copper kagome materials based on natural minerals Herbertsmithite [ZnCu3(OH)6Cl2] and Barlowite[Cu4(OH)6FBr]. Using ab-initio density functional theory calculations we estimate the stability of the hypothetical compounds against structural distortions and analyze their electronic and magnetic properties. We find that materials based on Herbertsmithite present an ideal playground for investigating the interplay of non-trivial band-topology and strong electronic correlation effects. In particular, we propose candidates for the Quantum Spin Hall effect at filling 4/3 and the Quantum Anomalous Hall effect at filling 2/3. For the Barlowite system we point out a route to realize a Quantum Spin Liquid.

  4. Non-trivial role of interlayer cation states in iron-based superconductors

    Science.gov (United States)

    Valenti, Roser; Guterding, Daniel; Jeschke, Harald O.; Glasbrenner, J. K.; Bascones, E.; Mazin, I. I.

    Unconventional superconductivity in iron pnictides and chalcogenides has been suggested to be controlled by the interplay of low-energy antiferromagnetic spin fluctuations and the particular topology of the Fermi surface in these materials. Under this assumption, one would expect the large class of isostructural and isoelectronic iron germanide compounds to be good superconductors, but they aren't. In this talk we will argue that superconductivity in iron germanides is suppressed by strong ferromagnetic tendencies, which surprisingly do not originate from changes in bond-angles or bond-distances with respect to iron pnictides, but are due to changes in the electronic structure in a wide range of energies happening upon substitution of atom species (As by Ge and the corresponding spacer cations). We will discuss the implications of these results in the general context of Fe-based superconductors. Funding by the Deutsche Forschungsgemeinschaft is acknowledged.

    We report modeling of the thermal boundary layer in turbulent Rayleigh-Bénard convection (RBC), which incorporates the effect of turbulent fluctuations. The study is based on the thermal boundary layer equation from Shishkina et al., and new Direct Numerical Simulations (DNS) of RBC in a cylindrical cell of the aspect ratio 1, for the Prandtl number variation of several orders of magnitude. Our modeled temperature profiles are found to agree with the DNS much better than those obtained with the classical Prandtl-Blasius or Falkner-Skan approaches.

    2016-09-01

    The formation of a non-neutral boundary sheath in front of material surfaces is universal plasma phenomenon. Despite several decades of research, however, not all related issues are fully clarified. In a recent paper, Chabert pointed out that this lack of clarity applies even to the seemingly innocuous question ``What the size of a floating sheath?'' This contribution attempts to provide an answer that is not arbitrary: The size of a floating sheath is defined as the plate separation of an equivalent parallel plate capacitor. The consequences of the definition are explored with the help of a self-consistent sheath model, and a comparison is made with other sheath size definitions.

  7. Probing anomalous quartic gauge-boson couplings via e+e-→4 fermions +γ

    Denner, A.; Dittmaier, S.; Roth, M.; Wackeroth, D.

    2001-01-01

    All lowest-order amplitudes for e + e - →4fγ are calculated including five anomalous quartic gauge-boson couplings that are allowed by electromagnetic gauge invariance and the custodial SU(2) c symmetry. Three of these anomalous couplings correspond to the operators L 0 ,L c , and L n that have been constrained by the LEP collaborations in WWγ production. The anomalous couplings are incorporated in the Monte Carlo generator RacoonWW(RacoonWW fellow of the Deutsche Forschungsgemeinschaft). Moreover, for the processes e + e - →4fγ RacoonWW is improved upon including leading universal electroweak corrections such as initial-state radiation. The discussion of numerical results illustrates the size of the leading corrections as well as the impact of the anomalous quartic couplings for LEP2 energies and at 500 GeV. (orig.)

  8. Supply Chain Engineering and the Use of a Supporting Knowledge Management Application

    Laakmann, Frank

    The future competition in markets will happen between logistics networks and no longer between enterprises. A new approach for supporting the engineering of logistics networks is developed by this research as a part of the Collaborative Research Centre (SFB) 559: "Modeling of Large Networks in Logistics" at the University of Dortmund together with the Fraunhofer-Institute of Material Flow and Logistics founded by Deutsche Forschungsgemeinschaft (DFG). Based on a reference model for logistics processes, the process chain model, a guideline for logistics engineers is developed to manage the different types of design tasks of logistics networks. The technical background of this solution is a collaborative knowledge management application. This paper will introduce how new Internet-based technologies support supply chain design projects.

    Optimization problems subject to constraints governed by partial differential equations (PDEs) are among the most challenging problems in the context of industrial, economical and medical applications. Almost the entire range of problems in this field of research was studied and further explored as part of the Deutsche Forschungsgemeinschaft (DFG) priority program 1253 on “Optimization with Partial Differential Equations” from 2006 to 2013. The investigations were motivated by the fascinating potential applications and challenging mathematical problems that arise in the field of PDE constrained optimization. New analytic and algorithmic paradigms have been developed, implemented and validated in the context of real-world applications. In this special volume, contributions from more than fifteen German universities combine the results of this interdisciplinary program with a focus on applied mathematics.   The book is divided into five sections on “Constrained Optimization, Identification and Control”...

    2017-11-01

    We present an algorithm to calculate the Nusselt number (Nu) in measurements of the heat transport in turbulent Rayleigh-Bénard convection under general non-Oberbeck-Boussinesq (NOB) conditions. We further critically analyze the different ways to evaluate the dependences of Nu over the Rayleigh number (Ra) and show the sensitivity of these dependences to the reference temperatures in the bulk, top and bottom boundary layers (BLs). Finally we propose a method to predict the bulk temperature and a way to calculate the reference temperatures of the top and bottom BLs and validate them against the Göttingen measurements.

    2014-01-01

    In April 2007, the  Deutsche Forschungsgemeinschaft (DFG) approved the  Priority Program 1324 “Mathematical Methods for Extracting Quantifiable Information from Complex Systems.” This volume presents a comprehensive overview of the most important results obtained over the course of the program.   Mathematical models of complex systems provide the foundation for further technological developments in science, engineering and computational finance.  Motivated by the trend toward steadily increasing computer power, ever more realistic models have been developed in recent years. These models have also become increasingly complex, and their numerical treatment poses serious challenges.   Recent developments in mathematics suggest that, in the long run, much more powerful numerical solution strategies could be derived if the interconnections between the different fields of research were systematically exploited at a conceptual level. Accordingly, a deeper understanding of the mathematical foundations as w...

  17. A thermodynamically and microscopically motivated constitutive model for piezoceramics

    International Nuclear Information System (INIS)

    Kamlah, M.; Wang, Z.

    2003-07-01

    This progress report presents a thermodynamically and microscopically motivated constitutive model for piezoceramics within the framework of a research project supported by the Deutsche Forschungsgemeinschaft. This project is aimed at developing a finite element tool for the analysis of piezoceramic components taking into account the full range of large signal electromechanical hysteresis effects exhibited by these materials. Such a tool is necessary for the stress analysis being the basis for a reliability assessment of piezoceramic devices subject to domain switching processes. In a first step, the hysteresis phenomena of piezoceramics and their microscopic origin were discussed, and the phenomena to be described were selected. Concerning the balance laws, the simplest form consisting of balance of momentum and Gauss' Law was derived by physically motivated assumptions step by step from nonlinear thermomechanics and Maxwell's Equations. Revision of the current literature revealed that a commonly accepted thermodynamic framework for phenomenological modeling has been established in the international scientific discussion. (orig.)

    2014-02-01

    Full Text Available The aim of this paper is threefold. First, it aspires to discuss some general considerations regarding the treatment of word-forming elements in a bilingual dictionary. It is argued that not few lexicographic decisions are to be made rather independently of fluctuating linguistic postulates and that the user aspect and the function of the respective dictionary should be paid special attention to. Second, the paper examines the quantity and quality of the information provided on affixes in two German-Czech dictionaries. The analysis focuses on the entry components terminology, spelling, pronunciation, input and output units, sense distinction, translation equivalents, examples, cross-references, usage labels and productivity as well as on selectional criteria and information on affixes in the outside matter. The analysis reveals that the dictionaries under scrutiny show considerable weaknesses with respect to the information provided. Third, the paper briefly describes the treatment of the German prefix/circumfix Ge-...(-e in the emerging Large German-Czech Academic Dictionary, an output of a project pursued at the Institute of Germanic Studies, Faculty of Philosophy & Arts, Charles University in Prague. It is shown how contrastive analysis can be supplemented by a corpus-based view using new corpus-linguistic tools.

    Special technical terms used in the world of insurance can hardly be found in general dictionaries. This is a gap which the 'Insurance dictionary' now presented is designed to fill. In view of its supplementary function, the number of terms covered is limited to 1200. To make this dictionary especially convenient for ready reference, only the most commonly used translations are given for each key word in any of the four languages. This dictionary is subdivided into four parts, each containing the translation of the selected terms in the three other languages. To further facilitate the use of the booklet, paper of different colours was used for the printing of the German, English, French and Greek sections. The present volume was developed from a Swedish insurance dictionary (Fickordbok Foersaekring), published in 1967, which - with Swedish as the key language- offers English, French and German translations of the basic insurance terms.

    From 2010 to 2011, Germany's domestic lignite output edged up 4.2% from 169.4 mill. t to 176.5 mill. t. This output is equivalent to a net calorific value of 54.4 mill. tce; of the total output, 157.4 mill. t, or some 90% was used in utility power plants for public supply. That was 3.6% more than in the previous year; 15.5 mill. t was input in the factories of the lignite-mining industry to make solid products, while 2.6 mill. t was used to generate electricity in mine-mouth power plants. Other sales of raw lignite and changes in stocks accounted for 1.0 mill. t. Lignite made a 24.9% contribution toward Germany's total power generation in 2011. In 2011, lignite had an 11.7% share in primary-energy consumption, giving it slot four in Germany's energy-consumption balance after mineral oil (34.0%), natural gas (20.4%) and hard coal (12.6%). Renewable resources cover 10.9, while nuclear energy accounts for 8.8% and other energy sources for 1.6%. With output of 54.4 mill. tce, lignite held a share of 38,5% in Germany's primary-energy production of some 141.3 mill. tce. The contributions made by the other energy carriers to primary-energy production in 2011 were as follows: 12.3 mill. tce hard coal, 13.1 mill. tce gas, 3.9 mill tce mineral oil, 49.5 mill. tce renewables, and 8.1 mill. tce other energy sources. Of the total electricity that Germany produced in 2011, 24,9% was accounted for by lignite. This means that lignite led the ranking of the most important input energies for electricity generation in 2011, followed by renewables with 19.9% hard coal with 18.6%, nuclear energy with 17.6% and gas with 13.7%. Other energy sources made a 5.3% contribution to total gross power generation. The most important ratios for the contributions made by the various lignite-mining areas to Germany's energy supply was shown. CO{sub 2} emissions from lignite rose 3.7% from 168.7 mill. t in 2010 to 175 mill. t in 2011. In the entire period from 1990 to 2011, a decline of some 167 mill. t, or 49%, was noted. Lignite's share in total CO{sub 2} emissions in Germany (incl. industrial processes, they amounted to 796 mill. t in 2011) has thus fallen from 33% in the base year of the Kyoto Protocol to 22%.

    From 2011 to 2012, Germany's domestic lignite output edged up to 5.1% from 176.5 mill. t to 185.4 mill. t. This figure is equivalent to a net calorific value of 57.2 mill. tce. Of the total output, 166.3 mill. t, or some 90%, was used in utility power plants for the public supply, i.e. 5.7% more than in the previous year. In addition, 15.1 mill. t was input in the factories of the lignite-mining industry to make solid products, while 3.0 mill. t was used to generate electricity in mine-mouth power plants. Other sales of raw lignite and changes in stocks accounted for 1.0 mill. t. Lignite made a 25.7% contribution toward Germany's total power generation in 2012. In 2012, lignite had a 12.1% share in primary-energy consumption balance after mineral oil (33.1%), natural gas (21.6%) and hard coal (12.2%). Renewable resources cover 11.6%, while nuclear energy accounts for 8.0% and other energy sources for 1.4%. With output of 57.2 mill. tce, lignite held a share of 38.4% in Germany's primary-energy production of some 149 mill. tce in 2012. The contributions made by other energy carriers to primary-energy production in 2012 were as follows: 11.1 mill. tce hard coal, 13.3 mill. tce gas, 3.8 mill. tce mineral oil, 54.0 mill. tce renewables, and 9.5 mill. tce other energy sources. Of the total electricity amount that Germany produced in 2012, 25.7% was accounted for by lignite. This means that lignite led the ranking of the most important input energies for electricity generation in 2012, followed by renewables with 22.1%, hard coal with 19.1%, nuclear energy with 16.1% and gas with 11.3%. Other energy sources made a 5.7% contribution to total gross power generation. The most important ratios for the contributions made by the various lignite-mining areas to Germany's energy supply are shown. CO{sub 2} emissions from lignite rose 5.1% from 173.9 mill. t in 2011 to 182.8 mill. t in 2012. In the total period from 1990 to 2012, a decline of 159.4 mill. t, or 46.6%, was noted. Hence, lignite's share in total CO{sub 2} emissions in Germany (including industrial processes, they amounted to 814 mill. t in 2012) fell from 32.8% in 1990 to 22.5% in 2012. (orig.)

    Quantum algorithms can be used to efficiently solve certain classically intractable problems by exploiting quantum parallelism. However, the effectiveness of quantum entanglement in quantum computing remains a question of debate. This study presents a new quantum algorithm that shows entanglement could provide advantages over both classical algorithms and quantum algo- rithms without entanglement. Experiments are implemented to demonstrate the proposed algorithm using superconducting qubits. Results show the viability of the algorithm and suggest that entanglement is essential in obtaining quantum speedup for certain problems in quantum computing. The study provides reliable and clear guidance for developing useful quantum algorithms.

    2015-11-01

    Full Text Available The article investigates the interrelations within the language system between anglicisms and newly formed native German words. New words emerge in German either spontaneously or under the supervision of philological associations. When created spontaneously new words are in most cases translation loans and retain the inner form and semantic connection between the components similar to that of a borrowed angliсism. Artificially created German neologisms, on the contrary, lose their semantic connection with the borrowing. Structural and semantic analysis of anglicisms and German neologisms enables to discover possible causes of giving preference to anglicisms in one cases and replacing them with German neologisms in others. The article debates the issues of language maintenance and conscious word creation.

    2003-01-01

    Full Text Available In this paper, a semantic analysis is presented of the Dutch particle 'toch' and its German cognate 'doch'. On the formal level they may appear as either adverb, conjunction or interjection, and they also occur in different sentence types. It is argued that the core meaning of both particles is the same. The range of uses differs, however, between the two languages. For example, German 'doch' can be used as an 'answering particle’ in reaction to a negative statement or question. This is not possible in Dutch. The core meaning of the particles can be explicated in terms of three steps: the utterance with 'toch'/'doch' represents a positive step. This step is preceded (implicitly or explicitly by a negative step, which is in turn preceded by a positive step wich is identical to the actual positive step. For certain uses of 'toch' and 'doch', however, we have to assume a modification of this general schema. A Dutch novel (by Maarten 't Hart, 1983 and its German translation was used as a corpus. The original text contained 270 occurrences of 'toch', and the translation 230 'doch'’s.

Given the pressing issues of climate protection, continuity of energy supply, and the prices of energy resources, the future of nuclear power can well be seen in an optimistic light. There will be a reassessment of nuclear power also in Germany because of the realities to be faced. If you really want to protect the climate, you cannot exclude the nuclear power option. (orig.)

    After the nuclear catastrophe in Fukushima Finland and Sweden have chosen completely different paths compared to Germany: both countries plan to build new nuclear power plants. The contribution discusses the historical development of nuclear power in these countries. In Sweden a political polarization exists between those who want to use renewable energies and those who expect increasing greenhouse gas emissions in case of nuclear power phaseout. In Finland no important anti-nuclear movement has been formed. The authors do not expect a change of policy in Sweden and Finland.

    Directory of Open Access Journals (Sweden)

    Ommer, Andreas

    2012-10-01

    Full Text Available [english] Background: Rectovaginal fistulas are rare, and the majority is of traumatic origin. The most common causes are obstetric trauma, local infection, and rectal surgery. This guideline does not cover rectovaginal fistulas that are caused by chronic inflammatory bowel disease.Methods: A systematic review of the literature was undertaken. Results: Rectovaginal fistula is diagnosed on the basis of the patient history and the clinical examination. Other pathologies should be ruled out by endoscopy, endosonography or tomography. The assessment of sphincter function is valuable for surgical planning (potential simultaneous sphincter reconstruction.Persistent rectovaginal fistulas generally require surgical treatment. Various surgical procedures have been described. The most common procedure involves a transrectal approach with endorectal suture. The transperineal approach is primarily used in case of simultaneous sphincter reconstruction. In recurrent fistulas. Closure can be achieved by the interposition of autologous tissue (Martius flap, gracilis muscle or biologically degradable materials. In higher fistulas, abdominal approaches are used as well. Stoma creation is more frequently required in rectovaginal fistulas than in anal fistulas. The decision regarding stoma creation should be primarily based on the extent of the local defect and the resulting burden on the patient.Conclusion: In this clinical S3-Guideline, instructions for diagnosis and treatment of rectovaginal fistulas are described for the first time in Germany. Given the low evidence level, this guideline is to be considered of descriptive character only. Recommendations for diagnostics and treatment are primarily based the clinical experience of the guideline group and cannot be fully supported by the literature.[german] Hintergrund: Rektovaginale Fisteln stellen eine seltene Erkrankung dar. Die Mehrzahl der rektovaginalen Fisteln ist traumatischer Genese. Die wichtigsten Ursachen stellen Entbindungstraumata, lokale Infektionen und Eingriffe am Rektum dar. Rektovaginale Fisteln bei chronisch-entzündlichen Darmerkrankungen werden in dieser Leitlinie nicht behandelt.Methode: Es wurde ein systematisches Review der Literatur durchgeführt. Ergebnisse: Die Diagnose einer rektovaginalen Fistel ergibt sich aus Anamnese und klinischer Untersuchung. Andere pathologische Veränderungen sollten durch Zusatzuntersuchungen (Endoskopie, Endosonographie, Schichtuntersuchung ausgeschlossen werden. Eine Beurteilung der Sphinkterfunktion ist für die Planung des operativen Vorgehens (Frage der simultanen Sphinkterrekonstruktion sinnvoll.Eine persistierende rektovaginale Fistel kann in der Regel nur durch eine Operation zur Ausheilung gebracht werden. Es wurden verschiedene Operationsverfahren mit niedrigem Evidenzniveau beschrieben. Am häufigsten ist das transrektale Vorgehen mit endorektaler Naht. Der transperineale Zugang kommt in erster Linie bei simultaner Schließmuskelrekonstruktion zur Anwendung. Bei rezidivierenden Fisteln kann durch die Interposition von körpereigenem Gewebe (Martius-Lappen, M.gracilis ein Verschluss erzielt werden. In neuen Studien wurde auch ein Verschluss durch Einbringen von Biomaterialien vorgestellt. Bei höher gelegenen Fisteln kommen auch abdominelle Verfahren zur Anwendung. Häufiger als bei der Behandlung von Analfisteln ist bei der rektovaginalen Fistel eine Stomaanlage erforderlich. Je nach Ätiologie (v.a. Rektumresektion wurde bei einem Teil der Patientinnen bereits ein Stoma im Rahmen der Primäroperation angelegt. Die Indikation zur Stomaanlage sollte sich in erster Linie nach dem Ausmaß des lokalen Defektes und der daraus resultierenden Belastung der betroffenen Frau richten.Schlussfolgerung: In dieser klinischen Leitlinie werden zum ersten Mal in Deutschland Richtlinien für die Behandlung der rektovaginalen Fisteln basierend auf einer systematischen Literaturanalyse vorgestellt. Aufgrund des niedrigen Evidenzniveaus kann die vorliegende Leitlinie nur einen deskriptiven Charakter haben. Empfehlung für Diagnostik und Therapie beruhen überwiegend auf den klinischen Erfahrungen der Leitliniengruppe und können nicht durch die vorhandene Literatur komplett abgedeckt werden.

    Within a generous financial framework investments in wind energy power have rapidly increased in Germany since the late 1980's. In addition to direct subsidies or incentive stipulated by statutory provisions the DtA has encouraged investments in wind energy projects by loans at preferential interest rates with tremendous success and it will continue to do so. At present especially new ways of supporting environmental investments are being seek which have a cross-border environmental impact. The goal is to provide financial assistance both to domestic and foreign companies willing to invest in transboundary projects which may be located in East European Countries

    2011-12-01

    After the end of the Great War, private as well as public research funding in Austria was anaemic and slow to develop. Whereas the German state-funded Deutsche Forschungsgemeinschaft (DFG) was established as early as 1920, first steps in that direction were only taken in Austria in the late 1920s. In 1929, the Osterreichisch-deutsche Wissenschaftshilfe (ODW) was founded under the auspices of the Austrian Academy of Sciences and the DFG. Although prima facie on an equal footing, the new research funding organisation was in fact highly dependent on its German cooperation partner. The article explores for the first time ODW's position within the German and Austrian science and foreign policies, which aimed to promote the idea of unification of both states within the German Reich. A quantitative analysis of the subsidies policy in the first five years of existence shows that the ODW gave financial aid primarily to conservative research fields, affecting the intellectual balance of power in the First Austrian Republic. Policy continuities and discontinuities of the organisation in the course of the national-socialist rise to power in Germany after 1933 are examined in the second part of the article. The article thus both increases our knowledge about the most important German research funding organisation DFG, and identifies some of the fundamental structural features of Austrian science policy in the interwar years.

    In this paper new results of the research regarding the design of the first experimental plant for a hot-gas screw-type machine are reported. Target of the development is the verification of operating behaviour as well as the thermal and mechanical behaviour of the screw-type motor parts. The selection and dimensioning of the plant components is described with a main focus on the construction of the thermally high-loaded hot-gas screw-type engine. Its manufacturing tolerances are based on simulations, with which the mechanical deformations of the rotors and the casing respective the resulting clearance-heights can be calculated. With inclusion of an efficient cooling method for the motor parts, for the, in the article documented, projected nominal working condition with a material-depending limit for the entrance temperature at {theta}{sub E,} {sub M}=600 C, a pressure ratio {pi}=6 and a male rotor peripheral speed u{sub HR}=120 ms{sup -1}, each rotor should be decreased by 0.07 mm.

    Electron beam tomography (EBT) has been scientifically evaluated to a much lesser degree for non-cardiac indications than for cardiac purposes. Therefore, four groups of investigators in Berlin (2), Mannheim and Muenchen, which were supported by the Deutsche Forschungsgemeinschaft (DFG), included applications outside the heart in their evaluation of EBT technology. EBT has proven useful to look for pulmonary embolism and to assess other vessels (aorta, aortic branches, and intracranial arteries). Imaging of the lung parenchyma benefits from its intrinsic high contrast and from the fast data acquisition of EBT. Limited photon efficiency, higher radiation exposure, increased noise levels and other artifacts, however markedly reduce the value of EBT for imaging of low contrast objects compared to conventional spiral CT and multislice CT (MSCT), compromising, in particular, the morphologic depiction of parenchymal abdominal organs and the brain. Consequently, scientific studies to further evaluate EBT for scanning of the brain and parenchymal abdominal organs were not pursued. Radiation exposure for non-cardiac EBT studies is up to three times higher than that for respective spiral CT studies, and in children EBT can only be advocated in select cases. Radiation exposure for the various prospectively triggered cardiac examination protocols of EBT is lower than that for conventional coronary angiography. Radiation exposure in cardiac multislice CT exceeds severalfold that of EBT, but the dose efficiency of EBT and MSCT are similar due to higher spatial resolution and less image noise of MSCT. In addition, modifications of MSCT (ECG pulsing) can further reduce radiation exposure to the level of EBT. Technical improvements of the EBT successor scanner 'e-Speed' enable faster data acquisiton at higher spatial resolution. Within comparative studies, the 'e-Speed' will have to prove its value and competitiveness, particularly in comparison with multislice CT. After profound

    In order to attain the targets of climatic protection and in order to guarantee a safe supply of energy, a committed climatic program and energy program have to be submitted. The Federal Republic of Germany can attain this without rehabilitating the atomic energy. In addition, the development of the technologies has to be supported for the promotion of renewable energies. The national policy must strengthen their commitment and start initiatives for energy conservation. For this, the following aspects are suggested: (a) Enhancement of the energy standards of electrical appliances; (b) Minimization of the losses of energy due to the ''Stand By '' function of electrical appliances; (c) Promotion of investments in clean coal technologies and in technologies of combined heat and power generation; (d) Further avoidance of losses with the use of fossil sources of energy; (e) Auction of the free of charge certificates; (f) reduction the network charges; (g) coordinated energy policy on European level.

    When light weight structural applications are of prime concern, magnesium cannot be ignored. When magnesium is of prime concern, of course, the research cannot be ignored, either. Since there is not much to be ignored (or not), however, it is the research on MgLi that takes the lead in the German press. ''Rock-solid as Kruppstahl'' was it meant to be, though MgLi-alloys soften quite appreciable already at ambient temperature. A hydrogen treatment of the MgLi melt was the phenomenon that was naturally astounded. In the meantime, however, it became very tranquilly around the contest for the selection of the species from the ''MgLi-Born''. Has the hot air already escaped Warm wind is not bad in each case. Daily discipline, however, has scaled ever since with the natural beauty of the more concrete results by working. What follows is an article that looks upon this particular German variant at the ''histoire parallele'' in the field of metallic innovations as well as upon the sound base of such deliberately outbalanced renaissances.

    Prediction is very difficult, especially if it's about the future. This witticism, which has been alternatively ascribed to Mark Twain, Karl Valentin, Niels Bohr and Winston Churchill, could hardly be truer than when applied to the wind and sun, especially in the case of long-term forecasts. Wind power and photovoltaic plant capacities are what needs to grow most if renewable energies really are to cover 80% of Germany's energy supply by the year 2050. Other renewable energy resources do not have the potential to contribute substantially to achieving the goals proclaimed by the German federal government. Some 64% of electricity production and 70% of installed power capacity will be coming from the wind and sun in the year 2050, according to recent calculations. A study prepared by Prognos AG on behalf of the German National Committee of the World Energy Council has investigated the question as to what extent international hydropower storages are capable of taking up surplus electricity and holding it available as a power reserve.

    Oral diseases rank among the most prevalent non-communicable diseases in modern societies. In Germany, oral epidemiological data show that both dental caries and periodontal diseases are highly prevalent, though significant improvements in oral health has been taking in the population within the last decades, particularly in children. It is, therefore, the aim of the Fifth German Oral Health Study (DMS V) to actualize the data on current oral health status and to gather information on oral health behavior and risk factors. In addition to current oral health monitoring, the study will also permit conclusions about trends in the development of oral health in Germany between 1989 and 2014. DMS V is a cross-sectional, multi-center, nationwide representative, socio-epidemiological study to investigate the oral health status und behavior of the German resident population in four age cohorts. Study participants are children (12-year-olds), adults (35- to 44-year-olds), young olds (65- to 74-year-olds), and old olds (75- to 100-year-olds) who are drawn from local residents' registration offices. Social-science investigation parameters concern subjective perceptions and attitudes regarding oral health and nutrition, sense of coherence, and socio-demographic data. Clinical oral parameters are tooth loss, caries and periodontitis, prosthodontic status, further developmental and acquired dental hard tissue and mucosal lesions. To ensure reproducibility, the dental investigators are trained and calibrated by experts and multiple reliability checks are performed throughout the field phase. Statistical analyses are calculated according to a detailed statistical analysis plan. The DMS studies first performed in 1989, 1992 and repeated in 1997 and 2005 are the only cross-sectional oral health studies conducted in Germany on a population-based national representative level. Updated prevalence and trend analyses of key oral diseases are, therefore, of major epidemiological and health services research interest.

    Based on the event tree analysis as documented in the Appendix 1, the failure probabilities of the system functions required to control the initiating events are evaluated in this Appendix 2. The reliability investigations necessary for the evaluation of the event sequences are performed mostly by means of the fault tree analysis. The methods of the reliability analysis, the composition and function of the systems important to safety and the functional tests performed on these systems are dealt with in detail. The comprehensive documentation of the reliability analyses as performed for the internal events necessitated a division of this Appendix 2 into two volumes.

    Standardization achievements in the field of radiology induced the IEC to compile the terminology used in its safety and application standards and present it in publication 788 (1984 issue), entitled 'Medical radiology terminology'. The objective pursued is to foster the use of standard terminology in the radiology standards. The value of publication 788 lies in the fact that it presents definitions of terms used in the French and English versions of IEC standards in the field of radiology, and thus facilitates adequate translation of these terms into other languages. In the glossary in hand, German-language definitions have been adopted from the DIN standards in cases where the French or English versions of definitions are identical with the German wording or meaning. The numbers of DIN standards or sections are then given without brackets, ahead of the text of the definition. In cases where correspondance of the various texts is not so good, or reference should be made to a term in a DIN standard, the numbers are given in brackets.

    [Objective] When English-speaking people listen to the Deutseh “high-low” word illusion,they report hearing English words.Whether Chinese-speaking people report Chinese words when listening to the illusion,or whether any reported words might be correlated with personality traits as previous investigations have demonstrated for listening to music in other cultures,is open to question.The present study aimed to address this.[Methods] A total of 308 right-handed,healthy volunteers (177 women and 131 men) were given the illusion test and asked to answer the Zuckerman-Kuhlman personality questionnaire (ZKPQ).Their depressive tendency was measured by the Plutchik-van Praag depression inventory (PVP).[Results] There was no gender effect regarding either the PVP score or the number of reported Chinese words from the illusion.Women scored higher on ZKPQ neuroticism-anxiety than men.The number of meaningful Chinese words reported was correlated with the ZKPQ impulsive sensation-seeking,aggression-hostility,and activity scores.Some words reported by participants who scored higher on these three traits were related in meaning to those scales.[[Conclusion

    Cleaning of municipal and industrial waste water is done by means of biological processes: micro-organisms degrade pollutants. The resulting products are, besides cleaned waste water, sewage sludge and surplus sludge. Their disposal involves ecological and economic problems. One approach to their partial disposal is their degradation in a digester. Approximately one half of the organic substance is converted by anaerobic bacteria into energy-rich biogas. Optimization of this digestion process accelerates the anaerobic degradation process, increases the accruing amount of digester gas and reduces the volume of digested sludge to be disposed of. With these objectives, the Institute fuer Mechanische Verfahrenstechnik is conducting research into the mechanical treatment of micro-organisms remaining in surplus sludge by means of different treatment devices. The project is sponsored under the programme of the Deutsche Forschungsgemeinschaft DFG ``Biological processes with dispersive solids``. Mechanical treatment renders the cell constituents exploitable to anaerobic bacteria; the resulting sludge degradation is more rapid and more complete.

Ein Weg zur partiellen Beseitigung dieser Klaerschlaemme ist ihr Abbau in einem Faulbehaelter. Dabei wird etwa die Haelfe der organischen Substanz durch anaerobe Bakterien zu einem energiereichen Biogas umgewandelt. Eine Optimierung dieses Faulprozesses beinhaltet: 1. Beschleunigung des anaeroben Abbauprozesses, 2. Erhoehung der anfallenden Faulgasmenge und 3. Reduzierung der zu entsorgenden Faulschlammenge.

    Microbial degradation of petroleum was investigated in intact sediment cores of Caspian Sea during a simulated petroleum seepage using a sediment-oil-flow-through (SOFT) system. Over the course of the SOFT experiment (190 days), distinct redox zones established and evolved in the sediment core. Methanogenesis and sulfate reduction were identified to be important processes in the anaerobic degradation of hydrocarbons. C1 to C6 n-alkanes were completely exhausted in the sulfate-reducing zone and some higher alkanes decreased during the upward migration of petroleum. A diversity of sulfate-reducing bacteria was identified by 16s rRNA phylogenetic studies, some of which are associated with marine seeps and petroleum degradation. The δ13C signal of produced methane decreased from -33.7‰ to -49.5‰ indicating crude oil degradation by methanogenesis, which was supported by enrichment culturing of methanogens with petroleum hydrocarbons and presence of methanogenic archaea. The SOFT system is, to the best of our knowledge, the first system that simulates an oil-seep like condition and enables live monitoring of biogeochemical changes within a sediment core during petroleum seepage. During our presentation we will compare the Caspian Sea data with other sediments we studied using the SOFT system from sites such as Santa Barbara (Pacific Ocean), the North Alex Mud Volcano (Mediterranean Sea) and the Eckernfoerde Bay (Baltic Sea). This research was funded by the Deutsche Forschungsgemeinschaft (SPP 1319) and DEA Deutsche Erdoel AG. Further support came from the Helmholtz and Max Planck Gesellschaft.

  3. Temperature boundary layer profiles in turbulent Rayleigh-Benard convection

    Classical boundary-layer theory for steady flows cannot adequately describe the boundary layer profiles in turbulent Rayleigh-Benard convection. We have developed a thermal boundary layer equation which takes into account fluctuations in terms of an eddy thermal diffusivity. Based on Prandtl's mixing length ideas, we relate the eddy thermal diffusivity to the stream function. With this proposed relation, we can solve the thermal boundary layer equation and obtain a closed-form expression for the dimensionless mean temperature profile in terms of two independent parameters: θ(ξ) =1/b∫0b ξ [ 1 +3a3/b3(η - arctan(η)) ] - c dη , where ξ is the similarity variable and the parameters a, b, and c are related by the condition θ(∞) = 1 . With a proper choice of the parameters, our predictions of the temperature profile are in excellent agreement with the results of our direct numerical simulations for a wide range of Prandtl numbers (Pr), from Pr=0.01 to Pr=2547.9.

  4. Observation of the Spin Nernst Effect in Platinum

    Science.gov (United States)

    Goennenwein, Sebastian

    Thermoelectric effects - arising from the interplay between thermal and charge transport phenomena - have been extensively studied and are considered well established. Upon taking into account the spin degree of freedom, however, qualitatively new phenomena arise. A prototype example for these so-called magneto-thermoelectric or spin-caloritronic effects is the spin Seebeck effect, in which a thermal gradient drives a pure spin current. In contrast to their thermoelectric counterparts, not all the spin-caloritronic effects predicted from theory have yet been observed in experiment. One of these `missing' phenomena is the spin Nernst effect, in which a thermal gradient gives rise to a transverse pure spin current. We have observed the spin Nernst effect in yttrium iron garnet/platinum (YIG/Pt) thin film bilayers. Upon applying a thermal gradient within the YIG/Pt bilayer plane, a pure spin current flows in the direction orthogonal to the thermal drive. We detect this spin current as a thermopower voltage, generated via magnetization-orientation dependent spin transfer into the adjacent YIG layer. Our data shows that the spin Nernst and the spin Hall effect in in Pt have different sign, but comparable magnitude, in agreement with first-principles calculations.

    An initial microstructure of C45 steel (Fe, 0.42-0.5% C, 0.5-0.8% Mn, <0.4% Si, <0.045% S, 0.045% P * All in wt%) was modified from ferritic-pearlitic to bainitic through heating at 900 C for 1 hour and quenching in a lead bath at 500 C for 30 min. The steel was processed by High Pressure Torsion (HPT) at room temperature for 3 and 5 rotations, which led to an ultrafine or nano-scale grained structure. Then the material was annealed at 400 C and 450 C for two hours, respectively. TEM observation showed that continuous recrystallization occurred during the annealing. The yield strength and elongation after annealing at 400 C and 450 C were 1277 MPa, 3%, and 1100 MPa, 11%, respectively. Compared with the mechanical properties before annealing, it was revealed that the continuous recrystallization during annealing led to an enhancement of the ductility, but without sacrificing much of the strength.

    In the course of research programs to develop a methodology for the study of microtopography of ice and snow surfaces, we placed a strong emphasis on the involvement of students. This project provided the opportunity to engage students in every step from building the instrument through development of the data processing, the actual field measurements, processing of the resultant data, their evaluation and interpretation to the final publication in scientific journals. The development of the Glacier Roughness Sensor (GRS) incorporating Global Positioning System (GPS) technology and the fieldwork on the Greenland Inland Ice were particularly fascinating and instructive for students. In a related snow-hydrological research project on Niwot Ridge in the Colorado Front Range, we involved students in two season-long measurement campaigns in a high alpine environment. Students from the Universität Trier, Germany, and the University of Colorado Boulder participated in this project to learn about the value of international collaboration in science. Funding was provided by Deutsche Forschungsgemeinschaft (Antarctic and Arctic Program) and the U.S. National Science Foundation (Hydrological Sciences Program). Students participated in preparatory classes and field camps, selected their own research projects and received university credit towards their degrees in geography or environmental sciences. All student participants in the MICROTOP projects have gone on to higher university education and become professionally exceptionally successful.

    The large scale thermal convection systems in geo- and astrophysics are usually influenced by Coriolis forces caused by the rotation of their celestial bodies. To better understand the influence of rotation on the convective flow field and the heat transport at these conditions, we study Rayleigh-Bénard convection, using pressurized sulfur hexaflouride (SF6) at up to 19 bars in a cylinder of diameter D=1.12 m and a height of L=2.24 m. The gas is heated from below and cooled from above and the convection cell sits on a rotating table inside a large pressure vessel (the "Uboot of Göttingen"). With this setup Rayleigh numbers of up to Ra =1015 can be reached, while Ekman numbers as low as Ek =10-8 are possible. The Prandtl number in these experiment is kept constant at Pr = 0 . 8 . We report on heat flux measurements (expressed by the Nusselt number Nu) as well as measurements from more than 150 temperature probes inside the flow. We thank the Deutsche Forschungsgemeinschaft (DFG) for financial support through SFB963: "Astrophysical Flow Instabilities and Turbulence". The work of GA was supported in part by the US National Science Foundation through Grant DMR11-58514.

  8. Control dynamics of interaction quenched ultracold bosons in periodically driven lattices

    2016-05-01

    The out-of-equilibrium dynamics of ultracold bosons following an interaction quench upon a periodically driven optical lattice is investigated. It is shown that an interaction quench triggers the inter-well tunneling dynamics, while for the intra-well dynamics breathing and cradle-like processes can be generated. In particular, the occurrence of a resonance between the cradle and tunneling modes is revealed. On the other hand, the employed periodic driving enforces the bosons in the mirror wells to oscillate out-of-phase and to exhibit a dipole mode, while in the central well the cloud experiences a breathing mode. The dynamical behaviour of the system is investigated with respect to the driving frequency revealing a resonant behaviour of the intra-well dynamics. To drive the system in a highly non-equilibrium state an interaction quench upon the driving is performed giving rise to admixtures of excitations in the outer wells, an enhanced breathing in the center and an amplification of the tunneling dynamics. As a result of the quench the system experiences multiple resonances between the inter- and intra-well dynamics at different quench amplitudes.

  9. Fatigue crack paths under the influence of changes in stiffness

    Directory of Open Access Journals (Sweden)

    G. Kullmer

    2016-02-01

    Full Text Available An important topic of the Collaborative Research Centre TRR 30 of the Deutsche Forschungsgemeinschaft (DFG is the crack growth behaviour in graded materials. In addition, the growth of cracks in the neighbourhood of regions and through regions with different material properties belongs under this topic. Due to the different material properties, regions with differing stiffness compared to the base material may arise. Regions with differing stiffness also arise from ribs, grooves or boreholes. Since secure findings on the propagation behaviour of fatigue cracks are essential for the evaluation of the safety of components and structures, the growth of cracks near changes in stiffness has to be considered, too. Depending on the way a crack penetrates the zone of influence of such a change in stiffness and depending on whether this region is more compliant or stiffer than the surrounding area the crack may grow towards or away from this region. Both cases result in curved crack paths that cannot be explained only by the global loading situation. To evaluate the influence of regions with differing stiffness on the path of fatigue cracks the paths and the stress intensity factors of cracks growing near and through regions with differing stiffness are numerically determined with the program system ADAPCRACK3D. Therefore, arrangements of changes in stiffness modelled as material inclusions with stiffness properties different from the base material or modelled as ribs and grooves are systematically varied to develop basic conclusions about the crack growth behaviour near and through changes in stiffness.

  10. Origin of superconductivity in KFe2As2 under positive and negative pressures and relation to other Fe-based families

    Science.gov (United States)

    Valenti, Roser

    KFe2As2 shows an intricate behavior as a function of pressure. At ambient pressure the system is superconductor with a low critical temperature Tc=3.4 K and follows a V-shaped pressure dependence of Tc for moderate pressures with a local minimum at a pressure of 1.5 GPa. Under high pressures Pc=15 GPa, KFe2As2 exhibits a structural phase transition from a tetragonal to a collapsed tetragonal phase accompanied by a boost of the superconducting critical temperature up to 12 K. On the other hand, negative pressures realized through substitution of K by Cs or Rb decrease Tc down to 2.25K. In this talk we will discuss recent progress on the understanding of the microscopic origin of this pressure-dependent behavior by considering a combination of ab initio density functional theory with dynamical mean field theory and spin fluctuation theory calculations. We will argue that a Lifshitz transition associated with the structural collapse changes the pairing symmetry from d-wave (tetragonal) to s+/- (collapsed tetragonal) at high pressures while at ambient and negative pressures correlation effects appear to be detrimental for superconductivity. Further, we shall establish cross-links to the chalcogenide family, in particular FeSe under pressure. The Deutsche Forschungsgemeinschaft (DFG) is gratefully acknowledged for financial support.

  11. Importance of liquid fragility for energy applications of ionic liquids

    Science.gov (United States)

    Sippel, Pit; Lunkenheimer, Peter; Krohns, Stephan; Thoms, Erik; Loidl, Alois

    Ionic liquids (ILs) are salts that are liquid at ambient temperatures. The strong electrostatic forces between their molecular ions result, e.g., in low volatility and high stability for many members of this huge material class. For this reason they bear a high potential for new advancements in applications, e.g., as electrolytes in energy-storage devices such as supercapacitors or batteries, where the ionic conductivity is an essential figure of merit. Most ILs show dynamic properties typical for glassy matter, which dominate many of their physical properties. An important method to study these dynamical glass-properties is dielectric spectroscopy that can access relaxation times of dynamic processes and the conductivity in a broad frequency and temperature range. In the present contribution, we present results on a large variety of ionic liquids showing that the conductivity of ILs depends in a systematic way not only on their glass temperature but also on the so-called fragility, characterizing the non-canonical super-Arrhenius temperature dependence of their ionic mobility.

    Changes in the potential energy and entropy of water molecules hydrating biomolecular interfaces play a significant role for biomolecular solubility and association. Free energy perturbation and thermodynamic integration methods allow calculations of free energy differences between two states from simulations. However, these methods are computationally demanding and do not provide insights into individual thermodynamic contributions, i.e. changes in the solvent energy or entropy. Here, we employ methods to spatially resolve distributions of hydration water thermodynamic properties in the vicinity of biomolecular surfaces. This allows direct insights into thermodynamic signatures of the hydration of hydrophobic and hydrophilic solvent accessible sites of proteins and small molecules and comparisons to ideal model surfaces. We correlate dynamic properties of hydration water molecules, i.e. translational and rotational mobility, to their thermodynamics. The latter can be used as a guide to extract thermodynamic information from experimental measurements of site-resolved water dynamics. Further, we study energy-entropy compensations of water at different hydration sites of biomolecular surfaces.

    Recent experimental advances have introduced an interplay in the trapping length scales of the lattice and the harmonic confinement. This fact motivates the investigation to prepare atomic gases at certain quantum states by utilizing a composite atomic trap consisting of a lattice potential that is embedded inside an overlying harmonic trap. In the present work, we examine how frequency modulations of the overlying harmonic trap stimulate the dynamics of an 1D few-boson gas. The gas is initially prepared at a highly confined state, and the subsequent dynamics induced by a quench of the harmonic trap frequency to a lower value is examined. It is shown that a non-interacting gas always diffuses to the outer sites. In contrast the response of the interacting system is more involved and is dominated by a resonance, which is induced by the bifurcation of the low-lying eigenstates. Our study reveals that the position of the resonance depends both on the atom number and the interaction coupling, manifesting its many body nature. The corresponding mean field treatment as well as the single-band approximation have been found to be inadequate for the description of the tunneling dynamics in the interacting case.

    The quantum anomalous Hall effect has been theoretically predicted and experimentally verified in magnetic topological insulators. In addition, the surface states of these materials exhibit a hedgehog-like ``spin'' texture in momentum space. Here, we apply the previously formulated low-energy model for Bi2Se3, a parent compound for magnetic topological insulators, to a slab geometry in which an exchange field acts only within one of the surface layers. In this sample set up, the hedgehog transforms into a skyrmion texture beyond a critical exchange field. This critical field marks a transition between two topologically distinct phases. The topological phase transition takes place without energy gap closing at the Fermi level and leaves the transverse Hall conductance unchanged and quantized to e2 / 2 h . The momentum-space skyrmion texture persists in a finite field range. It may find its realization in hybrid heterostructures with an interface between a three-dimensional topological insulator and a ferromagnetic insulator.

    The CBELSA/TAPS experiment at ELSA measures double polarization observables in meson photoproduction off protons and neutrons. To be able to measure purely neutral reactions off polarized neutrons with high efficiency, the main calorimeter has to be integrated into the first level trigger. This requires to exchange the existing PIN photo diode by a new avalanche photo diode (APD) readout. The newly developed readout electronics will provide an energy resolution compatible to the previous set-up and a fast trigger signal down to 10 MeV energy deposit per crystal. After the successful final tests with a 3x3 CsI crystal matrix in Bonn at ELSA and in Mainz at MAMI all front-end electronics were produced in fall 2013. Automated test routines for the front-end electronics were developed and the characterization measurements of all APDs were successfully accomplished in Bonn.

  16. Optical fingerprints of solid-liquid interfaces: a joint ATR-IR and first principles investigation

    Despite the importance of understanding the structural and bonding properties of solid-liquid interfaces for a wide range of (photo-)electrochemical applications, there are presently no experimental techniques available to directly probe the microscopic structure of solid-liquid interfaces. To develop robust strategies to interpret experiments and validate theory, we carried out attenuated total internal reflection (ATR-IR) spectroscopy measurements and ab initio molecular dynamics (AIMD) simulations of the vibrational properties of interfaces between liquid water and well-controlled prototypical semiconductor substrates. We show the Ge(100)/H2O interface to feature a reversible potential-dependent surface phase transition between Ge-H and Ge-OH termination. The Si(100)/H2O interface is proposed as a model system for corrosion and oxidation processes. We performed AIMD calculations under finite electric fields, revealing different pathways for initial oxidation. These pathways are predicted to exhibit unique spectral signatures. A significant increase in surface specificity can be achieved utilizing an angle-dependent ATR-IR experiment, which allows to detect such signatures at the interfacial layer and consequently changes in the hydrogen bond network.

    We discuss the nonequilibrium dynamics in two interaction quantum quenches in the one-dimensional Fermi-Hubbard model. First, we study the decay of the Néel state as a function of interaction strength. We observe a fast charge dynamics over which double occupancies are built up, while the long-time decay of the staggered moment is controlled by spin excitations, corroborated by the analysis of the entanglement dynamics. Second, we investigate the formation of Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) correlations in a spin-imbalanced system in quenches from the noninteracting case to attractive interactions. Even though the quench puts the system at a finite energy density, peaks at the characteristic FFLO quasimomenta are visible in the quasi-momentum distribution function, albeit with an exponential decay of s-wave pairing correlations. We also discuss the imprinting of FFLO correlations onto repulsively bound pairs and their rapid decay in ramps. Supported by the DFG (Deutsche Forschungsgemeinschaft) via FOR 1807.

    A group of objects passing through a constriction might get eventually stuck. It occurs no matter what type of object is considered: sand in an hourglass, particles in a fluid through a porous medium or people leaving a room in panic. The case of particles in a fluid affects porous mediums, filters and membranes, which become unusable when clogged. Certainly the adherence of the particles to the walls and to each other is an important parameter in such systems, but even without adherence the clogging probability is far from negligible. Focusing in these low-adherence regimes, we use microfluidic devices with a bottleneck of squared cross-section through which we force dilute polystyrene particle solutions with diameters comparable to the bottleneck size and down to one tenth its size. In such low friction conditions we show experimental evidence of a strong transition at a critical particle-to-neck ratio, just as it occurs in dry granular systems. We describe analytically such a transition by modeling the arch formation as a purely stochastic process, which yields a good agreement with the experimental data.

  19. Exploring the nonequilibrium dynamics of ultracold quantum gases by using numerical tools

    Science.gov (United States)

    Heidrich-Meisner, Fabian

    Numerical tools such as exact diagonalization or the density matrix renormalization group method have been vital for the study of the nonequilibrium dynamics of strongly correlated many-body systems. Moreover, they provided unique insight for the interpretation of quantum gas experiments, whenever a direct comparison with theory is possible. By considering the example of the experiment by Ronzheimer et al., in which both an interaction quench and the release of bosons from a trap into an empty optical lattice (sudden expansion) was realized, I discuss several nonequilibrium effects of strongly interacting quantum gases. These include the thermalization of a closed quantum system and its connection to the eigenstate thermalization hypothesis, nonequilibrium mass transport, dynamical fermionization, and transient phenomena such as quantum distillation or dynamical quasicondensation. I highlight the role of integrability in giving rise to ballistic transport in strongly interacting 1D systems and in determining the asymptotic state after a quantum quench. The talk concludes with a perspective on open questions concerning 2D systems and the numerical simulation of their nonequilibrium dynamics.

    High power laser fields enabled by technologies developed for ground-based gravitational-wave observatories open up new opportunities for fundamental physics studies. One of these options is the search for axions and axion-like particles in a pure laboratory experiment. The axion is a solution to the strong CP-problem and a potential dark matter candidate. The axion has also been proposed as an additional channel to cool stars as well as a potential explanation for the TeV transparency problem. The German-US ALPS collaboration is setting up a light-shining-through-walls (LSW) experiment at DESY. LSW experiments are based on the simple idea that a high power laser field traversing a static magnetic field will transform partly into a relativistic axion field. This axion field will travel through an opaque wall into a second static magnetic field region where it turns partly back into an electromagnetic wave field with the same frequency as the laser. The ALPS collaboration is working towards a large scale LSW experiment at DESY in Hamburg, Germany. I will report on the status of the ALPS experiment.

    Jeschke, Harald O.; Altmeyer, Michaela; Rozenberg, Marcelo; Gabay, Marc; Valenti, Roser

    We investigate the electronic structure and spin texture at the (001) surface of SrTiO3 in the presence of oxygen vacancies by means of ab initio density functional theory (DFT) calculations of slabs. Relativistic non-magnetic DFT calculations exhibit Rashba-like spin winding with a characteristic energy scale ~ 10 meV. However, when surface magnetism on the Ti ions is included, bands become spin-split with an energy difference ~ 100 meV at the Γ point. This energy scale is comparable to the observations in SARPES experiments performed on the two-dimensional electronic states confined near the (001) surface of SrTiO3. We find the spin polarized state to be the ground state of the system, and while magnetism tends to suppress the effects of the relativistic Rashba interaction, signatures of it are still clearly visible in terms of complex spin textures.

    High-resolution Fourier transform microwave (FTMW) spectroscopy studies of 207PbF have demonstrated the near-degeneracy of two levels of opposite parity. These have attracted attention for the study of parity violation effects and the variation of fundamental constants using 207PbF. Further theoretical work has improved our detailed understanding of both 207PbF and 208PbF, and furthermore recently indicated that the finely split +/- parity levels grow monotonically closer for higher vibrational states. Our experimental results for v = 0-3 confirm this, and are in excellent agreement with our extended theoretical calculations up to v = 4; both will be presented.

  4. The effect of centrifugal buoyancy on the heat transport in rotating Rayleigh-Bénard convection

    2017-11-01

    In a rapidly rotating and differentially heated fluid, the centrifugal acceleration can play a similar role to that of gravity in generating convective motion. However, in the paradigm system of rotating Rayleigh-Bénard convection, centrifugal buoyancy is typically not considered in theoretical studies and, thus, usually undesired in laboratory experiments, despite being unavoidable. How centrifugal buoyancy affects the turbulent flow, including the heat transport, is still largely unknown, in particular, when it can be considered negligible. We study this problem by means of direct numerical simulations. Unlike in experiments, we are able to systematically vary the Froude number Fr (ratio of centrifugal to gravitational acceleration) and the Rossby number Ro (dimensionless rotation rate) independently, and even set each to zero exactly. We show that the centrifugal acceleration simultaneously leads to contending phenomena, e.g. reflected by an increase and a decrease of the center temperature, or a suppression and an enhancement of the heat transfer efficiency. Which one prevails as net effect strongly depends on the combination of Fr and Ro. Furthermore, we discuss implications for experiments of rapidly rotating convection.

    From sand dunes to Faraday heaping, driven granular matter, i.e., large agglomeration of macroscopic particles, is rich pattern forming system. When a granular material is partially wet (e.g., wet sand on the beach), a different pattern forming scenario arises due to the cohesive particle-particle interactions. Here, we focus on the formation of density-wave fronts in an oscillated wet granular layer undergoing a gas-liquid-like transition. The threshold of the instability is governed by the amplitude of the vertical vibrations. Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of the container with leading edges. They are stable beyond a critical distance from the container center. Based on the measurement of the critical distance and the rotation frequency, we propose a model for the pattern formation by considering the competition between the time scale for the collapse of cohesive particles and that of the energy injection resisting this process.

  6. Stabilization of Reactive MgO Surfaces by Ni Doping

    Mazheika, Aliaksei; Levchenko, Sergey V.

    Ni-MgO solid solutions are promising materials for catalytic reduction of CO2 and dry reforming of CH4. To explain the catalytic activity, an ab initio study of Ni-substitutional defects in MgO (NiMg) has been performed. At first, the validation of the theory level was done. We compared results of CCSD(T) embedded-cluster calculations of NiMg formation energies and adsorption energies of CO, CO2 and H2 on them to the HSE(α) hybrid DFT functional with the fraction of the exact exchange α varied between 0 and 1. HSE(0.3) was found to be the best compromise in this study. Our periodic HSE(0.3) calculations show that NiMg defects are most stable at corner sites, followed by steps, and are least stable at (001) terraces. Thus, Ni-doping stabilizes stepped MgO surfaces. The dissociative adsorption of H2 on the terrace is found to be endothermic (+ 1 . 1 eV), whereas on (110) surface with NiMg it is highly exothermic (- 1 . 6 eV). Adsorbed CO2 is also significantly stabilized (- 0 . 6 vs. - 2 . 2 eV). These findings explain recent microcalorimetry measurements of H2 and CO2 adsorption at doped Ni-MgO samples. partially supported by UniCat (Deutsche Forschungsgemeinschaft).

    The dynamics of dark bright solitons beyond the mean-field approximation is investigated. We first examine the case of a single dark-bright soliton and its oscillations within a parabolic trap. Subsequently, we move to the setting of collisions, comparing the mean-field approximation to that involving multiple orbitals in both the dark and the bright component. Fragmentation is present and significantly affects the dynamics, especially in the case of slower solitons and in that of lower atom numbers. It is shown that the presence of fragmentation allows for bipartite entanglement between the distinguishable species. Most importantly the interplay between fragmentation and entanglement leads to the decay of each of the initial mean-field dark-bright solitons into fast and slow fragmented dark-bright structures. A variety of excitations including dark-bright solitons in multiple (concurrently populated) orbitals is observed. Dark-antidark states and domain-wall-bright soliton complexes can also be observed to arise spontaneously in the beyond mean-field dynamics.

    Time-resolved tomographic flow fields measured in the viscous sublayer region of a turbulent boundary layer subjected to an adverse pressure gradient (APG) are examined with the aim to resolve and characterize reverse flow events at Reτ = 5000. The fields were measured using a novel high resolution tomographic particle tracking technique. It is shown that this technique is able to fully resolve mean and time dependent features of the complex three-dimensional flow with high accuracy down to very near-wall distances ( 10 μm). From time resolved Lagrangian particle trajectories, statistical information as well as instantaneous topological features of near-wall flow events are deduced. Similar to the zero pressure gradient case (ZPG), it was found that individual events with reverse flow components still occur relatively rarely under the action of the pressure gradient investigated here. However, reverse flow events comprised of many individual events, are shown to appear in relatively organized groupings in both spanwise and streamise directions. Furthermore, instantaneous measurements of reverse flow events show that these events are associated with the motion of low-momentum streaks in the near-wall region.

    Impulsive or 3He-rich solar energetic particle (SEP) events have been typically associated with jets or small EUV brightenings. We identify 30 impulsive SEP events from ACE at L1 during the solar minimum period 2007-2010 and examine their solar sources with high resolution STEREO-A EUV images. At beginning of 2007, STEREO-A was near the Earth while at the end of the investigated period, when there were more events, STEREO-A was leading the Earth by 90°. Thus STEREO-A provided a better (more direct) view on 3He-rich flares generally located on the western Sun's hemisphere. Surprisingly, we find that about half of the events are associated with large-scale EUV coronal waves. This finding provides new insights on acceleration and transport of 3He-rich SEPs in solar corona. It is believed that elemental and isotopic fractionation in impulsive SEP events is caused by more localized processes operating in the flare sites. The EUV waves have been reported in gradual SEP events in association with fast coronal mass ejections. To examine their role on 3He-rich SEPs production the energy spectra and relative abundances are discussed. R. Bucik is supported by the Deutsche Forschungsgemeinschaft under grant BU 3115/2-1.

  11. Collective oscillations and coupled modes in confined microfluidic droplet arrays

    Schiller, Ulf D.; Fleury, Jean-Baptiste; Seemann, Ralf; Gompper, Gerhard

    Microfluidic droplets have a wide range of applications ranging from analytic assays in cellular biology to controlled mixing in chemical engineering. Ensembles of microfluidic droplets are interesting model systems for non-equilibrium many-body phenomena. When flowing in a microchannel, trains of droplets can form microfluidic crystals whose dynamics are governed by long-range hydrodynamic interactions and boundary effects. In this contribution, excitation mechanisms for collective waves in dense and confined microfluidic droplet arrays are investigated by experiments and computer simulations. We demonstrate that distinct modes can be excited by creating specific `defect' patterns in flowing droplet trains. While longitudinal modes exhibit a short-lived cascade of pairs of laterally displacing droplets, transversely excited modes form propagating waves that behave like microfluidic phonons. We show that the confinement induces a coupling between longitudinal and transverse modes. We also investigate the life time of the collective oscillations and discuss possible mechanisms for the onset of instabilities. Our results demonstrate that microfluidic phonons can exhibit effects beyond the linear theory, which can be studied particularly well in dense and confined systems.

    Köhler, T.; Schumann, O.; Biebl, F.; Kramer, S.; Kehrein, S.; Manmana, S.; Rajpurohit, S.; Sotoudeh, M.; Blöchl, P.

    We investigate 1D correlated systems following a photoexcitation by combining ab-initio methods, time-dependent matrix product state (MPS) approaches, analytical insights from linearized quantum Boltzmann equations (LBE), and molecular dynamics (MD) simulations to describe the dynamics on different time scales ranging from femto- up to nanoseconds. This is done for manganite systems in the material class Pr1-xCaxMnO3. We derive 1D ab-initio model Hamiltonians for which we compute the ground states at different values of the doping using MD simulations. At half doping, we obtain a magnetic microstructure of alternating dimers from which we derive a 1D Hubbard-type model. The dynamics is analyzed concerning the formation and lifetime of such quasiparticles via a LBE. We find that the magnetic microstructure strongly enhances the lifetime of the excitations. In this way, our work constitutes a first step to building a unifying theoretical framework for the description of photoexcitations in strongly correlated materials over a wide range of time scales, capable of making predictions for ongoing experiments investigating pump-probe situations and unconventional photovoltaics.

    We report about the feasibility of Lorentz force velocimetry (LFV) for various flow profiles. LFV is a contactless non-invasive technique to measure flow velocity and has been developed in the last years in our institute. This method is advantageous if the fluid is hot, aggressive or opaque like glass melts or liquid metal flows. The conducted experiments shall prove an increased versatility for industrial applications of this method. For the force measurement we use an electromagnetic force compensation balance. As electrolyte salty water is used with an electrical conductivity in the range of 0.035 which corresponds to tap water up to 20 Sm-1. Because the conductivity is six orders less than that of liquid metals, here the challenging bottleneck is the resolution of the measurement system. The results show only a slight influence in the force signal at symmetric and strongly asymmetric flow profiles. Furthermore we report about the application of LFV to stratified two-phase flows. We show that it is possible to detect interface instabilities, which is important for the dimensioning of liquid metal batteries. Deutsche Forschungsgemeinschaft DFG.

    Operating a liquid-metal battery produces Ohmic losses in the electrolyte layer that separates both metal electrodes. As a consequence, temperature gradients establish which potentially cause thermal convection since density and interfacial tension depend on the local temperature. In our numerical investigations, we considered three plane, immiscible layers governed by the Navier-Stokes-Boussinesq equations held at a constant temperature of 500°C at the bottom and top. A homogeneous current is applied that leads to a preferential heating of the mid electrolyte layer. We chose a typical material combination of Li separated by LiCl-KCl (a molten salt) from Pb-Bi for which we analyzed the linear stability of pure thermal conduction and performed three-dimensional direct-numerical simulations by a pseudospectral method probing different: electrolyte layer heights, overall heights, and current densities. Four instability mechanisms are identified, which are partly coupled to each other: buoyant convection in the upper electrode, buoyant convection in the molten salt layer, and Marangoni convection at both interfaces between molten salt and electrode. The global turbulent heat transfer follows scaling predictions for internally heated buoyant convection.

  15. From single magnetic adatoms on superconductors to coupled spin chains

    Franke, Katharina J.

    Magnetic adsorbates on conventional s-wave superconductors lead to exchange interactions that induce Yu-Shiba-Rusinov (YSR) states inside the superconducting energy gap. Here, we employ tunneling spectroscopy at 1.1 K to investigate magnetic atoms and chains on superconducting Pb surfaces. We show that individual Manganese (Mn) atoms give rise to a distinct number of YSR-states. The single-atom junctions are stable over several orders of magnitude in conductance. We identify single-electron tunneling as well as Andreev processes. When the atoms are brought into sufficiently close distance, the Shiba states hybridize, thus giving rise to states with bonding and anti-bonding character. It has been shown that the Pb(110) surface supports the self-assembly of Fe chains, which exhibit fingerprints of Majorana bound states. Using superconducting tips, we resolve a rich subgap structure including peaks at zero energy and low-energy resonances, which overlap with the putative Majorana states.

    The measurement of atmospheric ice nucleating particles (INP) is still challenging. In the absence of easily applicable INP standards the intercomparison of different methods during collaborative laboratory and field workshops is a valuable tool that can shine light on the performance of individual methods for the measurement of INP [1]. FIN-2 was conducted in March 2015 at the AIDA facility in Karlsruhe as an intercomparison of mobile instruments for measuring INP [2]. FIN-3 was a field campaign at the Desert Research Institutes Storm Peak Laboratory in Colorado in September 2015 [3]. The FRankfurt Ice nucleation Deposition freezinG Experiment (FRIDGE) participated in both experiments. FRIDGE measures ice nucleating particles by electrostatic precipitation of aerosol particles onto Si-wafers in a collection unit, followed by activation, growth, and optical detection of ice crystals on the substrate in an isostatic diffusion chamber [4,5]. We will present and discuss results of our measurements of deposition/condensation INP and of immersion INP with FRIDGE during FIN-2 and FIN-3.

  17. Mode-coupling of interaction quenched ultracold bosons in periodically driven lattices

    2016-05-01

    The out-of-equilibrium dynamics of interaction quenched finite ultracold bosonic ensembles in periodically driven one-dimensional optical lattices is investigated. As a first attempt a brief analysis of the dynamics caused exclusively by the periodically driven lattice is presented and the induced low-lying modes are introduced. It is shown that the periodic driving enforces the bosons in the outer wells to exhibit out-of-phase dipole-like modes, while in the central well the cloud experiences a local-breathing mode. The dynamical behavior of the system is investigated with respect to the driving frequency, revealing a resonant-like behavior of the intra-well dynamics. Subsequently, we drive the system to a highly non-equilibrium state by performing an interaction quench upon the periodically driven lattice. This protocol gives rise to admixtures of excitations in the outer wells, an enhanced breathing in the center and an amplification of the tunneling dynamics. As a result (of the quench) the system experiences multiple resonances between the inter- and intra-well dynamics at different quench amplitudes. Finally, our study reveals that the position of the resonances can be adjusted e.g. via the driving frequency or the atom number manifesting their many-body nature.

  18. Matrix-product-state method with local basis optimization for nonequilibrium electron-phonon systems

    We present a method for simulating the time evolution of quasi-one-dimensional correlated systems with strongly fluctuating bosonic degrees of freedom (e.g., phonons) using matrix product states. For this purpose we combine the time-evolving block decimation (TEBD) algorithm with a local basis optimization (LBO) approach. We discuss the performance of our approach in comparison to TEBD with a bare boson basis, exact diagonalization, and diagonalization in a limited functional space. TEBD with LBO can reduce the computational cost by orders of magnitude when boson fluctuations are large and thus it allows one to investigate problems that are out of reach of other approaches. First, we test our method on the non-equilibrium dynamics of a Holstein polaron and show that it allows us to study the regime of strong electron-phonon coupling. Second, the method is applied to the scattering of an electronic wave packet off a region with electron-phonon coupling. Our study reveals a rich physics including transient self-trapping and dissipation. Supported by Deutsche Forschungsgemeinschaft (DFG) via FOR 1807.

  20. A thermodynamically consistent model for granular-fluid mixtures considering pore pressure evolution and hypoplastic behavior

    2016-11-01

    A new mixture model for granular-fluid flows, which is thermodynamically consistent with the entropy principle, is presented. The extra pore pressure described by a pressure diffusion equation and the hypoplastic material behavior obeying a transport equation are taken into account. The model is applied to granular-fluid flows, using a closing assumption in conjunction with the dynamic fluid pressure to describe the pressure-like residual unknowns, hereby overcoming previous uncertainties in the modeling process. Besides the thermodynamically consistent modeling, numerical simulations are carried out and demonstrate physically reasonable results, including simple shear flow in order to investigate the vertical distribution of the physical quantities, and a mixture flow down an inclined plane by means of the depth-integrated model. Results presented give insight in the ability of the deduced model to capture the key characteristics of granular-fluid flows.

    We seek to extract the kinematic fingerprints of baryon resonances by making use of a high-quality beam of linearly polarized photons at the BGO-OD experiment at ELSA (Bonn, German). We constructed a unique device for precisely determining the degree of polarization in the coherent bremsstrahlung peak. Deflection of post-bremsstrahlung electrons in the magnetic field of the photon tagger provides precise information on the energy and polarization of the bremsstrahlung photons. And thereby will constrain the overall kinematics of the final-state particles in all decay channels of the photoproduced baryon resonances. We designed, prototyped, built, calibrated, and have been operating a three-layered, multi-stranded, scintillating-fiber detector for ensuring the quality of the linearly polarization of the photon beam. The overlapping 2.00-mm scintillating fibers form an array giving ARGUS over 500 channels. The very befitting name harkens to the mythological all-seeing creature Argus Panoptes, the multi-eyed giant.

  2. Iridates and RuCl3 - from Heisenberg antiferromagnets to potential Kitaev spin-liquids

    Science.gov (United States)

    van den Brink, Jeroen

    The observed richness of topological states on the single-electron level prompts the question what kind of topological phases can develop in more strongly correlated, many-body electron systems. Correlation effects, in particular intra- and inter-orbital electron-electron interactions, are very substantial in 3 d transition-metal compounds such as the copper oxides, but the spin-orbit coupling (SOC) is weak. In 5 d transition-metal compounds such as iridates, the interesting situation arises that the SOC and Coulomb interactions meet on the same energy scale. The electronic structure of iridates thus depends on a strong competition between the electronic hopping amplitudes, local energy-level splittings, electron-electron interaction strengths, and the SOC of the Ir 5d electrons. The interplay of these ingredients offers the potential to stabilise relatively well-understood states such as a 2D Heisenberg-like antiferromagnet in Sr2IrO4, but in principle also far more exotic ones, such a topological Kitaev quantum spin liquid, in (hyper)honeycomb iridates. I will discuss the microscopic electronic structures of these iridates, their proximity to idealized Heisenberg and Kitaev models and our contributions to establishing the physical factors that appear to have preempted the realization of quantum spin liquid phases so far and include a discussion on the 4d transition metal chloride RuCl3.

  3. Condensation and transport in the totally asymmetric inclusion process (TASIP)

    Science.gov (United States)

    Knebel, Johannes; Weber, Markus F.; Krueger, Torben; Frey, Erwin

    Transport phenomena are often modeled by the hopping of particles on regular lattices or networks. Such models describe, e.g., the exclusive movement of molecular motors along microtubules: no two motors may occupy the same site. In our work, we study inclusion processes that are the bosonic analogues of the fermionic exclusion processes. In inclusion processes, many particles may occupy a single site and hopping rates depend linearly on the occupation of departure and arrival sites. Particles thus attract other particles to their own site. Condensation occurs when particles collectively cluster in one or multiple sites, whereas other sites become depleted.We showed that inclusion processes describe both the selection of strategies in evolutionary zero-sum games and the condensation of non-interacting bosons into multiple quantum states in driven-dissipative systems. The condensation is captured by the antisymmetric Lotka-Volterra equation (ALVE), which constitutes a nonlinearly coupled dynamical system. We derived an algebraic method to analyze the ALVE and to determine the condensates. Our approach allows for the design of networks that result in condensates with oscillating occupations, and yields insight into the interplay between network topology and transport properties.

  4. Ising tricriticality in the extended Hubbard model with bond dimerization

    Fehske, Holger; Ejima, Satoshi; Lange, Florian; Essler, Fabian H. L.

    We explore the quantum phase transition between Peierls and charge-density-wave insulating states in the one-dimensional, half-filled, extended Hubbard model with explicit bond dimerization. We show that the critical line of the continuous Ising transition terminates at a tricritical point, belonging to the universality class of the tricritical Ising model with central charge c=7/10. Above this point, the quantum phase transition becomes first order. Employing a numerical matrix-product-state based (infinite) density-matrix renormalization group method we determine the ground-state phase diagram, the spin and two-particle charge excitations gaps, and the entanglement properties of the model with high precision. Performing a bosonization analysis we can derive a field description of the transition region in terms of a triple sine-Gordon model. This allows us to derive field theory predictions for the power-law (exponential) decay of the density-density (spin-spin) and bond-order-wave correlation functions, which are found to be in excellent agreement with our numerical results.

    2016-10-01

    Complex plasmas are an excellent model system for strong coupling phenomena. Under certain conditions the dust particles immersed into the plasma form crystals which can be analyzed in terms of structure and dynamics. Previous experiments focussed mostly on monodisperse particle systems whereas dusty plasmas in nature and technology are polydisperse. Thus, a first and important step towards experiments in polydisperse systems are binary mixtures. Recent experiments on binary mixtures under microgravity conditions observed a phase separation of particle species with different radii even for small size disparities. This contradicts several numerical studies of 2D binary mixtures. Therefore, dedicated experiments are required to gain more insight into the physics of polydisperse systems. In this contribution first ground based experiments on two-dimensional binary mixtures are presented. Particular attention is paid to the requirements for the generation of such systems which involve the consideration of the temporal evolution of the particle properties. Furthermore, the structure of these two-component crystals is analyzed and compared to simulations.

  6. Influence of chirp on laser-pulse amplification in Brillouin backscattering schemes

    2015-11-01

    Plasma-based amplification of laser pulses is currently discussed as a key component for the next generation of high-intensity laser systems, possibly enabling the generation of ultra-short pulses in the exawatt-zetawatt regime. In these scenarios the energy of a long pump pulse (several ps to ns of duration) is transferred to a short seed pulse via a plasma oscillation. Weakly- and strongly-coupled (sc) Brillouin backscattering have been identified as potential candidates for robust amplification scenarios. With the help of three-wave interaction models, we investigate the influence of a chirp of the pump beam on the seed amplification. We show that chirp can mitigate deleterious spontaneous Raman backscattering of the pump off noise and that at the same time the amplification dynamics due to Brillouin scattering is still intact. For the experimentally very interesting case of sc-Brillouin we find a dependence of the efficiency on the sign of the chirp.

    The command line version of SeismicHandler (SH), a scientific analysis tool for seismic waveform data developed around 1990, has been redesigned in the recent years, based on a project funded by the Deutsche Forschungsgemeinschaft (DFG). The aim was to address new data access techniques, simplified metadata handling and a modularized software design. As a result the program was rewritten in Python in its main parts, taking advantage of simplicity of this script language and its variety of well developed software libraries, including ObsPy. SHX provides an easy access to waveforms and metadata via arclink and FDSN webservice protocols, also access to event catalogs is implemented. With single commands whole networks or stations within a certain area may be read in, the metadata are retrieved from the servers and stored in a local database. For data processing the large set of SH commands is available, as well as the SH scripting language. Via this SH language scripts or additional Python modules the command set of SHX is easily extendable. The program is open source, tested on Linux operating systems, documentation and download is found at URL "https://www.seismic-handler.org/".

    Magnetic impurities on an s-wave superconductor induce Yu-Shiba-Rusinov (YSR) bound states within the excitation gap of the superconductor. Here, we investigate single manganese (Mn) atoms adsorbed on different surface orientations of superconducting lead (Pb) and the nature of their YSR states. Depending on the adsorption site and surface, we detect a distinct number and characteristic patterns of YSR states around the Mn atoms. We show that the YSR states inherit their properties from the Mn d levels, which are split by the surrounding crystal field. The periodicity of the long-range YSR oscillations allows us to identify a dominant coupling of the d states to the outer Fermi sheet of the two-band superconductor Pb. The long-range and directional nature of the states are promising for the design of coupled adatom structures, which could bear topological phases.

    Imidazole ring is a part of many biologically important molecules and drugs. Imidazole monomer, dimer and its complexes with water have earlier been studied using infrared spectroscopy in helium droplets^{1,2} and molecular beams^{3}. These studies were focussed on the N-H and O-H stretch regions, covering the spectral region of 3200-3800 \\wn. We have extended the studies on imidazole clusters into the ring vibration region. The imidazole clusters were isolated in helium droplets and were probed using a combination of infrared spectroscopy and mass spectrometry. The spectra in the region of 1000-1100 \\wn and 1300-1460 \\wn were recorded using quantum cascade lasers. Some of the observed bands could be assigned to imidazole monomer and higher order imidazole clusters, using pickup curve analysis and ab initio calculations. Work is still in progress. The results will be discussed in detail in the talk. References: 1) M.Y. Choi and R.E. Miller, J. Phys. Chem. A, 110, 9344 (2006). 2) M.Y. Choi and R.E. Miller, Chem. Phys.

  11. Quantum Quench Dynamics in the Transverse Field Ising Model at Non-zero Temperatures

    Science.gov (United States)

    Abeling, Nils; Kehrein, Stefan

    The recently discovered Dynamical Phase Transition denotes non-analytic behavior in the real time evolution of quantum systems in the thermodynamic limit and has been shown to occur in different systems at zero temperature [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)]. In this talk we present the extension of the analysis to non-zero temperature by studying a generalized form of the Loschmidt echo, the work distribution function, of a quantum quench in the transverse field Ising model. Although the quantitative behavior at non-zero temperatures still displays features derived from the zero temperature non-analyticities, it is shown that in this model dynamical phase transitions do not exist if T > 0 . This is a consequence of the system being initialized in a thermal state. Moreover, we elucidate how the Tasaki-Crooks-Jarzynski relation can be exploited as a symmetry relation for a global quench or to obtain the change of the equilibrium free energy density.

    For vertical convection, where a fluid is confined between two differently heated isothermal vertical walls, we investigate the heat and momentum transport, which are measured, respectively, by the Nusselt number Nu and the Reynolds number Re . For laminar vertical convection we derive analytically the dependence of Re and Nu on the Rayleigh number Ra and the Prandtl number Pr from our boundary layer equations and find two different scaling regimes: Nu Pr 1 / 4 Ra 1 / 4 , Re Pr - 1 / 2 Ra 1 / 2 for Pr > 1 . Direct numerical simulations for Ra from 105 to 1010 and Pr from 0.01 to 30 are in excellent ageement with our theoretical findings and show that the transition between the regimes takes place for Pr around 0.1. We summarize the results from and present new theoretical and numerical results for transitional and turbulent vertical convection.

    Impulsive solar energetic particle events, characterised by a peculiar elemental composition with the rare elements like 3He and ultra-heavy ions enhanced by factors up to ten thousand above their thermal abundance, have been puzzling for almost 50 years. The solar sources of these events have been commonly associated with coronal jets, believed to be a signature of magnetic reconnection involving field lines open to interplanetary space. Here we present some of the most intense events, highly enriched in both 3He and heavier ions. The corresponding high-resolution, extreme-ultraviolet imaging observations have revealed for the first time a helical structure in the source flare with a jet-like shape. A mini-filament at the base of the jet appears to trigger these events. The events were observed with the two Solar Terrestrial Relations Observatories on the backside of the Sun, during the period of increased solar activity in 2014. During the last decade, it has been established that the helical motions in coronal jets represent propagating Alfvén waves. Revealing such magnetic-untwisting waves in the solar sources of highly enriched events in this study is consistent with a stochastic acceleration mechanism. An examination of jets in previously reported impulsive solar energetic particle events indicates that they tend to be large-scale blowout jets, sometimes cleanly showing a twisted configuration.The work of R.

    1982-05-01

    The history of the development of the separation nozzle method for enrichment of the light uranium isotope is described as a contribution to a memorandum published by Deutsche Forschungsgemeinschaft. The work was triggered off by an effect which had been observed in fundamental studies on gas kinetics. Development up to the technical maturity covered a period of more than 25 years. The implementation of the project at the Karlsruhe Nuclear Research Center provided an adequate financial and technical framework, the employment of senior staff without limitations in time being of major importance for the continuity of work. The links established between the Institute and the University and the resulting opportunity of having doctoral theses written, on the other hand, gave rise to a permanent flow of young, highly qualified scientists and engineers. Thus the Institut's requirements for junior staff could be satisfied in an optimum way. Although the Center offered a variety of possibilities of internal technical cooperation, important developments were performed jointly with industrial firms experienced in related fields. By this, not only a steady flow of know-how had been accumulated but also the large-scale applicability was ensured at a later date of results jointly obtained. (orig.) [de

The SMOS L1C science product contains the dual and full (Stokes vector polarization brightness temperatures at L-band for multiple incidence angles. In order to use the L1C product, the measurements are processed by a number of procedures including radio frequency interference (RFI filters, conversion of the polarization plane from the antenna (X- & Y-pol to the Earth’s surface frame (H- & V-pol, and averaging to fixed classes of incidence angles. The software allows for the processing of data for the entire daily half-orbit product, or for specific regions of interest, and can be adapted as a bash-job to process a large number of data files e.g. for time series analysis. This paper describes the tool which was developed in GNU C++ with the capability to be compiled as MEX function to work with Octave or MATLAB® without any source code adjustment.

    The electric field strength is a basic parameter of non-thermal plasmas. Therefore, a profound knowledge of the electric field distribution is crucial. In this contribution a four wave mixing technique based on Coherent Anti-Stokes Raman spectroscopy (CARS) is used to measure electric field strengths in filamentary dielectric barrier discharges (DBDs). The discharges are operated with a pulsed voltage in nitrogen at atmospheric pressure. Small amounts hydrogen (10 vol%) are admixed as tracer gas to evaluate the electric field strength in the 1 mm discharge gap. Absolute values of the electric field strength are determined by calibration of the CARS setup with high voltage amplitudes below the ignition threshold of the arrangement. Alteration of the electric field strength has been observed during the internal polarity reversal and the breakdown process. In this case the major advantage over emission based methods is that this technique can be used independently from emission, e.g. in the pre-phase and in between two consecutive, opposite discharge pulses where no emission occurs at all.

    The Raptor kJ class 1053 nm Nd:Glass laser in the Phoenix laser laboratory at University of California, Los Angeles, is used to ablate a dense debris plasma from a graphite or plastic target embedded in a tenuous, uniform, and quiescent ambient magnetized plasma in the Large Plasma Device (LAPD) which provides a peak plasma density of ni ~ 1013 cm-3. Its background magnetic field can vary between 200 and 1200 G. Debris ions from laser produced plasma expand out conically with super-Alfvénic speed (MA ~ 2) and expel the background magnetic field and ambient ions to form a diamagnetic bubble. The debris plasma interacts with the ambient plasma and the magnetic field and acts as a piston which can create collisionless shocks. Flute-type instabilities, which are probably large Larmor radius Rayleigh Taylor instabilities or lower hybrid drift instabilities, are developed at the bubble edge and also observed in the experiment. The amplitude and wavelength dependence of the instabilities, which might be a strong function of debris to ambient mass to charge ratio, is studied and the experimental results are compared to the two dimensional hybrid simulations. the Deutsche Forschungsgemeinschaft in the framework of the Excellence Initiative Darmstadt Graduate School of Energy Science and Engineering (GSC1070).

    Lorentz force velocimetry is a new contactless technique to measure the velocities of hot and agressive conductiong liquids. The measurement of the Lorentz force on the magnet is highly sensitive to the velocity profile that is influenced by the magnetic field. Thus the knowlegde of the flow transformation and the influence of an inhomogeneous local magnetic field on liquid metal flow is essential for obtaining velocity information from the measured forces. We consider liquid metal flow in a square duct with electrically insulating walls under the influence of a magnetic point dipole using three-dimensional direct numerical simulations with a finite-difference method. The dipole acts as a magnetic obstacle. A wide range of parameters affects the created wake. In this canonical setting, we study the modification of the flow for different Hartmann and Reynolds numbers. We observe a strong dependence of the magnetic obstacle effect and the corresponding Lorentz force on the orientation of the dipole as well as on its position.

    2015-03-01

    We investigate theoretically the effect of polymer tension on the collective behaviour of reversible cross-links. We use a model of two parallel-aligned, weakly-bending wormlike chains with a regularly spaced sequence of binding sites subjected to a tensile force. Reversible cross-links attach and detach at the binding sites with an affinity controlled by a chemical potential. In a mean-field approach, we calculate the free energy of the system and we show the emergence of a free energy barrier which controls the reversible (un)binding. The tension affects the conformational entropy of the chains which competes with the binding energy of the cross-links. This competition gives rise to a sudden increase in the fraction of bound sites as the polymer tension increases. The force-induced first-order transition in the number of cross-links implies a sudden force-induced stiffening of the effective stretching modulus of the polymers. This mechanism may be relevant to the formation and stress-induced strengthening of stress fibers in the cytoskeleton. We acknowledge support by the Deutsche Forschungsgemeinschaft (DFG) via grant SFB-937/A1.

    2017-11-01

    Planer and three-dimensional flow field measurements along a flat plat boundary layer in the Trisonic Wind Tunnel Munich (TWM) are examined with the aim to characterize the scaling, spatial organization, and topology of large scale turbulent superstructures in compressible flow. This facility is ideal for this investigation as the ratio of boundary layer thickness to test section spanwise extent ratio is around 1/25, ensuring minimal sidewall and corner effects on turbulent structures in the center of the test section. A major difficulty in the experimental investigation of large scale features is the mutual size of the superstructures which can extend over many boundary layer thicknesses. Using multiple PIV systems, it was possible to capture the full spatial extent of large-scale structures over a range of Mach numbers from Ma = 0.3 - 3. To calculate the average large-scale structure length and spacing, the acquired vector fields were analyzed by statistical multi-point methods that show large scale structures with a correlation length of around 10 boundary layer thicknesses over the range of Mach numbers investigated. Furthermore, the average spacing between high and low momentum structures is on the order of a boundary layer thicknesses. This work is supported by the Priority Programme SPP 1881 Turbulent Superstructures of the Deutsche Forschungsgemeinschaft.

The project continues the former project SFB 696 (Sonderforschungsbereich regarding the Demand Compliant Design (DeCoDe and the corresponding system model that strengthens the knowledge management to create high-quality mechatronical systems. In contrast to the SFB, which comprised the reverse engineering of a belt conveyor, Q-ELF applied a workflow of methods for quality oriented development on a new product. The DeCoDe ensures a methodical development that connects different engineering domains. This connection is important because the most problems and malfunctions arise at the interface of different domains due to their different notations for example. This approach also enables a methodical comparison of different competing concepts to pick the best suited one. A genetic algorithm is presented to further decrease the design-space. The project was carried out to develop linear drives for intralogistic systems.

  3. Metrology study of high precision mm parts made by the deep x-ray lithography (LIGA) technique

    Microcomponents are increasingly applied in industrial products, e.g. smallest gears, springs or the watch industry. Apart from their small dimensions, such components are characterized by a high contour accuracy. Industry requires the tolerances to be in the µm range. Measurement of lateral dimensions in the mm range with submicrometer accuracy and precision, however, results in high requirements on measurement technology. The relevance of this problem is illustrated by the fact that the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has launched the Collaborative Research Center 1159 on 'New Strategies of Measurement and Inspection for the Production of Microsystems and Nanostructures'. The Institut für Mikrostrukturtechnik, Karlsruhe (Institute of Microstructure Technology, Karlsruhe), produces microstructures by means of the LIG(A) technique (German acronym for lithography, electrodeposition, molding). Presently, a coordinate measurement machine equipped with an optical fiber probe to measure these microstructures is being tested. This paper will particularly focus on the precision and accuracy of the machine. The rules of measurement system analysis will be applied for this purpose. Following the elimination of the systematic error, reproducibility of deep-etch x-ray lithography will be highlighted using the LIGA production of gold gears as an example

    This paper describes, first, the international community of social scientists working on global change, and elaborates on possible contributions to this community by German political scientists. Second, the paper examines three new conceptual approaches to analysing global change, namely the Syndromes of Global Change approach, Earth System Analysis, and Sustainability Science. The paper then elaborates on a number of ways in which German political science could respond to the academic and political challenges posed by global change. It concludes by emphasizing the need for a new approach, focusing on 'world environmental policy analysis' that would bridge traditional (environmental) policy analysis, international relations research, and comparative politics.

Steinbügl decided to concentrate on bilingual dictionaries, because this type of dictionary is relatively less well explored in metalexicographical literature. German-English examples are analysed and evaluated. Instead of selecting examples randomly, she uses a comparative corpus of 200 collocations she put together herself in accordance with scientific reasons explained in detail. She questions the selection of collocations from existing corpora for her purposes, because these corpora are based on competing collocational theories. In order to come to meaningful conclusions, she prefers to delineate her own research approach, also however investigating the structures of bilingual dictionaries and dictionary articles, as well as situations of dictionary use.

    The fifth edition of the 'Dictionary of Agriculture' has, like its predecessors, been set out in the proven and systematic way, namely according to linguistic subject matter. An alphabetical index in six languages and an additional index of Latin names and terms in current use means that the dictionary can be used as a technical dictionary as well as a systematic guide to terminology. Each term has been consecutively numbered throughout the systematic part of the dictionary. Since these numbers recur in every index, entries are both easy to find and easy to read. A natural selection had constantly to be made from the wealth of possible terms. Wherever possible, however, terms that are characteristic of a particular region have also been taken into account. The same is true of linguistic differences, e.g. between American and British English and between European and American Spanish as well as of regional peculiarities in language use in Germany, Austria, Switzerland, France and Belgium. Where popular plant names in addition to the scientific ones could not be ascertained - as was the case for Spanish, in particular - only the Latin names are listed, in accordance with general practice in Spanish specialist literature.

    Current events have placed energy at the very top of the political agenda. Electricity and heat supplies cannot be taken for granted. A conclusive long-term energy concept urgently needs to be developed to provide a stable and, above all, reliable framework. The coming Energy Summit is hoped to pave the way for that concept. Germany can gain advantages as a location of industry only by becoming more and more independent of politically unstable regions, i.e., above all by using a broad energy mix. In this respect, which is decisive in ensuring Germany's future, nuclear power must not be left out of consideration. A reassessment of nuclear power can be based on these fundamental statements: - In view of the rising demand for energy worldwide, no energy resource may be left out. - It is wrong to postulate a contrast between renewables and nuclear power. - Nuclear power makes a decisive contribution to the continuity of supply. Worldwide uranium reserves are good not only for 40-60 years but at least for 200 years, and their share in generating costs is minimal. - The CO 2 objectives can only be met by using nuclear power, renewable energy resources, achieving higher efficiency, and through saving energy. - There is no reason to doubt the safety of German nuclear power plants. - Opting out of the use of nuclear power would lead to a shortage in electricity generation, at least temporarily. - Solving the waste and spent fuel disposal problem is a political rather than a technical issue. - Nuclear power is a technology for the future.

    Lignite has a key role to play in the transformation of the energy system due to its specific structural features in terms of industry, company history, policy, economics, the environment and regional structures. Understanding these structural features of the German lignite industry is an important requirement for classifying the significance of the lignite industry up to now and for the redesigning of this industrial sector. From these environmental, economic and regulatory structural characteristics, which are interwoven in a variety of ways, the incentives arise for the mining and power plant operators to react to energy price signals or energy policy steering. The aim of this research study is to define these structural features, to compile comprehensively the basic data and information that is not always transparently available, to understand the interactions, to enable the navigation of issues that are partly very complex, and to classify into the long-term developments that are especially important for political and social processes. In 2016 approx. 12 percent of German primary energy consumption was met using lignite. At the same time, lignite has the highest carbon dioxide (CO2) emissions of the fossil fuels; it currently accounts for approx. 19 percent of Germany's total greenhouse gas emissions as well as approx. 46 percent of the total CO2 emissions of the electricity sector. As a result of the mining of lignite and its conversion into electricity, substantial adverse impacts beyond the entry of greenhouse gases into the Earth's atmosphere arise for other environmental media. These impacts include half of Germany's mercury emissions, approx. a third of its sulfur dioxide emissions and approx. a tenth of its nitrogen oxide emissions. Lignite mining in open-cast mines takes up a substantial amount of landscape and soil and requires huge interventions in the water balance. Relatively high costs arise for the recultivation and rehabilitation of the open-cast areas; these costs are generated during the operation of open-cast mines and the connected power plants and must be securely made available for the post-operational phase. In addition, land for settlements and transport is also utilized, which leads to (cost-intensive) diversions of transport infrastructures and resettlements with all the accompanying consequences for local communities, etc. Industrial-scale mining of lignite is performed over the last 130 years and its conversion into electricity in large-scale power plants over about the last 100 years has made a significant contribution to the energy supply in Germany. It has been used above all for heating with lignite briquettes, for fuel production during the various phases of self-sufficiency efforts in Germany and from the mid-twentieth century onwards for electricity production, which constitutes the predominant use of lignite in Germany today. The decrease in lignite production, which resulted mainly from the (energy) economic adjustment process and the collapse of the sales market for lignite briquettes in the German federal states, already reached a (temporary) end at the turn of the millennium. In contrast to other areas of electricity generation, fuel costs are not just a matter of quantity-related cost items; for lignite, much more complex economic considerations and incentive effects arise due to the extensive consideration of variable and fixed cost components. As a result of the large share of internal cost allocation processes in the integrated lignite companies, the specific economic situation of the German lignite industry is also significantly less transparent than that of electricity generating companies that obtain fuels according to the conditions of the international fuel markets. In this study, the various economic parameters and cost components of the lignite industry in Germany were analyzed using a number of sources and different methodological approaches. Fixed cost components in the production costs (approx. three quarters) are of crucial importance here, some of which cannot be reduced at all and some of which can only be reduced in the medium term (i.e. usually by 2025) if replacement investments and retrofitting investments can be avoided or the personnel decreased. In order to understand this challenge objectively, the profitability indicator LignIX was developed for electricity production from lignite in Germany. The more recent and foreseeable developments for this index show that only newer lignite-fired power plants still cover the full operating costs of the open-cast mines and power plants from the revenues on the electricity market, but can no longer earn the capital costs for investments. In the near future, older lignite power plants could face the situation that the necessary maintenance, retrofitting or expansion investments in the connected open-cast mines can no longer be refinanced and personnel costs can no longer be met; open-cast mining capacities are then decommissioned if these investments and costs can be effectively avoided.

In cooperation with China, now projects on the environmental impact of the Three Gorges Dam on the Yangtze as well as projects to water management issues have been started. These projects are presented in this paper.

    Purpose: Since 2003 the Radiological Society of North America (RSNA) has been developing a lexicon of standardized radiological terms (RadLex) intended to support the structured reporting of imaging observations and the indexing of teaching cases. The aim of this study was to translate the first version of the lexicon (1 - 2007) into German and to implement a language-independent online term browser. Materials and Methods: RadLex version 1 - 2007 contains 6303 terms in nine main categories. Two radiologists independently translated the lexicon using medical dictionaries. Terms translated differently were revised and translated by consensus. For the development of an online term browser, a text processing algorithm called morphosemantic indexing was used which splits up words into small semantic units and compares those units to language-specific subword thesauri. Results: In total 6240 of 6303 terms (99 %) were translated. Of those terms 3965 were German, 1893 were Latin, 359 were multilingual, and 23 were English terms that are also used in German and were therefore maintained. The online term browser supports a language-independent term search in RadLex (German/English) and other common medical terminology (e.g., ICD 10). The term browser displays term hierarchies and translations in different frames and the complexity of the result lists can be adapted by the user. Conclusion: RadLex version 1 - 2007 developed by the RSNA is now available in German and can be accessed online through a term browser with an efficient search function. This is an important precondition for the future comparison of national and international indexed radiological examination results and the interoperability between digital teaching resources.

    In principle cross-border electricity transmission can be accounted for by price differences between the relevant electricity exchanges. For any given level of electricity demand the price of electricity at the individual electricity exchanges is primarily influenced by fuel prices, power plant availability and the feed-in of electricity from renewable energy, and differences in electricity prices in turn are a determinant of cross-border transmission. Some may have been surprised by the high level of electricity export in the spring of 2011, only shortly after 8 GW of power plant capacity had been shut down as part of the nuclear energy phaseout. What in fact explains the existing export surplus are the continuing excess of power plant capacity, an efficient power plant fleet compared with other European countries and the continuing growth of renewable energies in Germany.

    Full Text Available Mit der sukzessiven Erosion des rabbinischen Normensystems und im Prozess der Verbürgerlichung, so die grundlegende These dieser Arbeit, wurden jüdische Frauen seit dem frühen 19. Jahrhundert nicht nur stärker als zuvor in die religiöse Kultur und Praxis integriert. Gleichermaßen gewannen auch Konzepte von Weiblichkeit entscheidend an Bedeutung für die Neuorientierung eines Judaismus bürgerlicher Prägung. Auf breiter Quellenbasis werden in Gender, Judaism and Bourgeois Culture in Germany, 1800–1870 die soziale und religiöse Praxis dieses historischen Wandels, die Programme und Auseinandersetzungen, aber auch die Grenzen dieser Neudefinitionen analysiert.The basic thesis of this work is that during the course of the successive erosion of the Rabbinical system of norms and the process of gentrification, Jewish women have become ever more strongly integrated into religious culture and practice since the early 19th century. Concurrently, the concept of femininity took on a decisive meaning for the new orientation of bourgeois-leaning Judaism. The book Gender, Judaism and Bourgeois Culture in Germany, 1800–1870, analyses the social and religious practice of this historical change, the programs and conflicts as well as the limits of these new definitions based on a broad selection of sources.

    The World-Climate-Summit 2016 in Paris agreed to exacerbated goals for climate protection. This paper will scrutinize whether Germany can comply with its Paris-obligations by continuing the ongoing German ''Energiewende''. The result is clear-cut: The German ''Energiewende'' is inadequate. Due to the cap-and-trade system of the EU the ''Energiewende'' can in no way contribute to climate protection.

  15. Germans want more cost fairness and proximity to citizens in the energy transition; Deutsche wollen mehr Kostengerechtigkeit und Buergernaehe bei der Energiewende

    Goals such as fairness, participation and social compatibility will play in the future an increasingly important role in the struggle to find the right solutions for the energy transition, be it in the reform of the allocation and remuneration system, the expansion of wind energy on land, the sector coupling or the heat and traffic turnaround. WWith the first ''Social sustainability barometer of the energy transition'', published in November 2017, the IASS presents a monitoring instrument with a comprehensive, empirically sustainable database on the social dimensions of energy turnaround: it records annually the attitudes, justice sensations, experiences and expectations of different population groups in Germany with regard to the energy transition and identifies social challenges and political needs for action. With some amazing results. [German] Ziele wie Gerechtigkeit, Beteiligung und Sozialvertraeglichkeit werden zukuenftig eine immer wichtigere Rolle beim Ringen um die richtigen Loesungen fuer die Energiewende spielen, sei es bei der Reform des Umlagen- und Entgeltsystems, dem Windenergieausbau an Land, der Sektorkopplung oder der Waerme- und Verkehrswende. Mit dem im November 2017 erstmals erschienenen ''Sozialen Nachhaltigkeitsbarometer der Energiewende'' legt das IASS ein Monitoringinstrument mit einer umfassenden, empirisch tragfaehigen Datenbasis zu den sozialen Dimensionen der Energiewende vor: Es erfasst jaehrlich die Einstellungen, Gerechtigkeitsempfindungen, Erfahrungen und Erwartungen verschiedener Bevoelkerungsgruppen in Deutschland im Hinblick auf die Energiewende und benennt gesellschaftliche Herausforderungen und politische Handlungsbedarfe. Mit teils erstaunlichen Ergebnissen.

    The author states that that Fukushima accident has shown that severe accident are controllable even in case of deficient planning. The crisis in Fukushima had Japan specific origin and was the result of severe carelessness. The German and Swiss safety technology would have prevented the escalation of the crisis. Fukushima delivers extensive experiences for the further improvement of infrastructure, training and accident management. The German phaseout hysteria is according to the author not based on facts.

    The development of the world economy and thus world trade continued to lose momentum in 2012. The main dampening factor was the unsolved debt crisis in the Euro zone. In Germany, the passenger transport services remained approx. 1% below last year's level. Only the demand for rail passenger traffic showed some growth. The framework conditions for goods traffic were negative for Germany. The traffic power decreased about nearly 2% and in the rail goods traffic by about 3%. The investments made by DB Netz regarded the existing infrastructure as well as new and extended rail sections. They served the preservation and renewal of the infrastructure and the simultaneous introduction of new technologies. In order to achieve the predicted goods traffic growth, sufficient network capacities are planned to be provided in the years to come. In the field of rail power supply, selected electro-technical installations will be renewed. The network control system of the main system control centre will be replaced and receives new functions in the network operation control optimising tools. In national and international markets, DB Systemtechnik offers railway transport companies and rail industry businesses special railway know-how packages. (orig.)

    Traditionally, multilingualism is valued in Finland. However, in an age of globalisation and internationalisation, with English as a lingua franca, it is worth asking what value languages other than English have. The aim of this study was to gauge the attitudes of Finnish university personnel towards the use of languages other than English, particularly German, thus revealing widespread language ideologies. The data for this study was comprised of approximately 2000 open-ended responses to a survey on the role of languages amongst Finnish university personnel in 2009. Content analysis was used to analyse the responses. The findings of this analysis showed that an ideology of multilingualism was clearly more widespread than an English-only ideology, and that the image of German has not as rapidly declined as the knowledge and use of the language. Despite this, the ideology of language use being connected to disciplines strongly persists.
