    1990-01-01

    The annual report of the accellerator laboratory documentates the numerous activities of the nuclear physicists at both Munich universities. It describes extensive experimental research work at the Munich tandem accelerator and at external research facilities, far-reaching theoretical investigations, and novel apparative developments. Focal points of present measurements at the tandem accellerator are work on the mechanism of heavy ion reactions: transfer below the barrier, emission of light particles and production of high energy gamma radiation. Additionally, the report documentates the experiments of Munich groups at external research facilities and apparative developments for such projects, e.g. myon-catalyzed hydrogen fusion, reactions with mesonic degree of freedom, interactions with antiprotons, and particularly heavy ion reactions at high energies. To be named too in this context are the detector developments of the laboratory for nuclear physics measuring techniques and the work of the two target laboratories. The brief survey of the work of the theorists demonstrates the diversity of activities and reflections which deal with nuclear structure and reaction dynamics: Detailed investigations of non-relativistic many-body models, work on collective degrees of freedom, and, increasingly, field-theoretical work considering subnuclear degrees of freedom. Of particular interest is hot, compressed nuclear matter, i.e. the nuclear equation of state. (orig./DG) [de

    The research reactor FRM-II of the Technische Universitaet Muenchen is now ready for the nuclear start-up, but still waiting for the operational license. The high-flux neutron-source FRM-II (8 x 10 14 n/(s cm 2 ) is a unique tool for solid state physics and materials research by neutron scattering, positron annihilation experiments and activation analysis, as well as for fundamental physics, isotope production, silicone doping, cancer therapy by irradiation with fission neutrons and for tomography with fast and thermal neutrons. Reactor built in facilities as a hot source, a cold source, an uranium loaded converter plate producing an intense beam of fission neutrons, allow to expand the range of usable neutron energies far beyond the thermal spectrum. In addition, a source providing an intense beam of fission products is planned to be constructed by the Ludwig-Maximilians-Universitaet Muenchen and a source of ultra cold neutrons is planned by the Physics Department of the Technische Universitaet Muenchen. The reactor is already prepared for both of these facilities. (author)

  15. A Case Report of Salmonella muenchen Enteritis Causing Rhabdomyolysis and Myocarditis in a Previously Healthy 26-Year-Old Man.

    This case report examines an unusual presentation of a non-typhoidal Salmonella serovar with limited prevalence in the literature. This is the first case report to associate specifically the Salmonella muenchen serovar with rhabdomyolysis and myocarditis. This case report reviews the diagnostic criteria for myocarditis and explores the diagnostic dilemma of troponin elevation in the setting of rhabdomyolysis. It demonstrates that Salmonella muenchen has the ability to present in a broad range of individuals with complications extending beyond classical gastrointestinal symptoms. This report also concludes that diagnosis of the many possible complications from non-typhoidal Salmonella infections can be difficult due to patient comorbidities, variability in the severity of the illnesses, laboratory test limitations, and imaging limitations. When a patient presents with elevated troponins in the setting of rhabdomyolysis a careful workup should be done to evaluate for ischemic causes, myocarditis, or false elevation secondary to rhabdomyolysis.

    2003-01-01

    The 'Technische Universitaet Muenchen' has built a new high-flux research reactor, the 'Forschungsreaktor Muenchen'-II. This new reactor will replace the 'Forschungsreaktor Muenchen' which has been operated very successfully for about 43 years. The 'Forschungsreaktor Muenchen'-II has been developed with first priority for beam-tube experiments, but it will also provide possibilities for irradiation experiments or isotope production. The reactor was designed to obtain a high and spectrally pure thermal neutron flux is available in a large volume outside of the core, where it is accessible for experimental use. In addition to beam-tubes which will end in the thermal neutron field there will be beam-tubes that will provide - with the help of 'spectrum shifters' -cold; hot and fast neutrons. Even through the thermal power of the 'Forschungsreaktor Muenchen'-II was limited to 20 MW an unperturbed maximum thermal neutron flux of about 8 x 10 14 cm -2 s -1 will be reached. Because of its 'compact-core-concept' the 'Forschungsreaktor Muenchen'-II will have the best flux-to-power-ratio worldwide: The fuel element and its highly enriched U 3 Si 2 -Al-fuel were tested during the licensing procedure of the 'Forschungsreaktor Muenchen'-II. Within the scope of this 'hydraulic test' the stability and the vibration behavior of the fuel plates as well as the long-tem behavior of the fuel element were investigated (Authors)

    In 2013, raw pork was the suspected vehicle of a large outbreak (n = 203 cases) of Salmonella Muenchen in the German federal state of Saxony. In 2014, we investigated an outbreak (n = 247 cases) caused by the same serovar affecting Saxony and three further federal states in the eastern part of Germany. Evidence from epidemiological, microbiological and trace-back investigations strongly implicated different raw pork products as outbreak vehicles. Trace-back analysis of S. Muenchen-contaminated raw pork sausages narrowed the possible source down to 54 pig farms, and S. Muenchen was detected in three of them, which traded animals with each other. One of these farms had already been the suspected source of the 2013 outbreak. S. Muenchen isolates from stool of patients in 2013 and 2014 as well as from food and environmental surface swabs of the three pig farms shared indistinguishable pulsed-field gel electrophoresis patterns. Our results indicate a common source of both outbreaks in the primary production of pigs. Current European regulations do not make provisions for Salmonella control measures on pig farms that have been involved in human disease outbreaks. In order to prevent future outbreaks, legislators should consider tightening regulations for Salmonella control in causative primary production settings.

    The hypervelocity accelerator at the Technische Universitaet Muenchen, FRG, accelerates small projectiles (0.1 to 1.0 mm diameter) to velocities around 20 km/s. The photographic equipment consists of two Cordin single-frame image converter cameras and one TRW image converter camera with streak units and multiple-frame units. They are used for plasma flow diagnostics and the measurement of the position and the velocity of the projectiles. The single-frame cameras are triggered with a Laser light bar and the photographic measurement of the projectile velocity will be compared with Doppler-Radar. (author)

    A constant increase of powerful combustion engines has lead to higher loads on the crankshaft drive and piston pin. To ensure a robust design the effective forces and movements at the piston pin have to be known. At the Technische Universitaet Muenchen, Chair of Internal Combustion Engines, a research project looked into the piston pins movement during engine operation. The main goal was to determine the rotary movements of the piston pin by measurement at a 4-l gas SI engine as a function of the engine load and speed and to clarify the mechanisms that cause the rotary movement of the piston pin especially in the small connecting rod eye.

    Due to dwindling resources, heavy price volatility and the unilateral dependency on crude oil, the demand for alternatives to diesel and gas fuels is increasing. Dimethylether (DME) seems to present a promising option. Early 2009, within the framework of a six month FVV project (keyword 'DME - Alternative Fuels', purpose No. 1005), a potential analysis of DME as a fuel was carried out at the Chair of Combustion Engines (LVK) at the Technische Universitaet Muenchen (TUM). This paper concludes important information about DME from the point of view of heavy duty engine development. (orig.)

    The knowledge of material research and its history is not very common among scientists and engineers alike. Within the scope of an interdisciplinary teaching project carried out for the first time in the summer semester 2014 and ever since then every summer semester at the University of Stuttgart, an attempt is made to approach material research both from a scientific, technical and historical perspective. The Material Testing and Materials Testing Institute in Stuttgart (MPA), the liquid crystals and the screen technology as well as the superconductivity were selected as topics, which have a long tradition in research and teaching in Stuttgart. In this anthology the materials of the teaching project are summarized. [German] Das Wissen um die Materialforschung und ihre Geschichte ist selbst unter Naturwissenschaftlern und Ingenieuren wenig verbreitet.

    Purpose of this study was to evaluate the outcome of stereotactic body radiotherapy (SBRT) of liver metastases and prognostic factors for local control and overall survival. From 2000 to 2009 74 patients with 91 metastases were treated at the Department for Radiation Therapy and Oncology (TU Muenchen). With an observed local control rate of 75% after 1 year, SBRT proved as an effective local treatment option. Unfortunately, systemic tumor progression still dominates long term survival in many patients.

    Full Text Available Heute sind nicht nur diverse gestaltungsbezogene Disziplinen gefragt, sich aktiv mit der Digitalisierung von Information und ihren Potentialen und Nebenwirkungen für Bildungsprozesse auseinander zu setzen. In Deutschland haben sich Technikdidaktik und informatische Bildung getrennt von Medienpädagogik und Mediendidaktik entwickelt und wurden entsprechend unabhängig voneinander betrieben. Dies gilt auch für die Ästhetische Bildung, die informatisch-technische Inhalte kaum je curricular in die Auseinandersetzung mit digitaler Medienkultur integriert hat, schon gar nicht systematisch. Im diesem Artikel wird, ausgehend vom Stand der Forschung (zur Integration informatischer Inhalte in die Medienbildung und den identifizierten Grundproblemen der Medienbildung zwecks Kompensation der Defizite, ein auf Gestaltung basierter Ansatz präsentiert, kontextualisiert und diskutiert, der Technikverständnis in ein Konzept integrierter Medienbildung einbezieht, dies als Bildungsziel im Sinne eines ganzheitlichen Verständnisses von Welt begreift und daher disziplinüberschreitend angelegt ist. Der Ansatz geht über technokratische Vorstellungen einer Technikdidaktik hinaus, die Medientechnologien isoliert von lebensbedeutsamen, ästhetisch-künstlerisch gestalteten Kontexten betrachtet und vermittelt. Im didaktischen Konzept werden die Grundlagen informatischer Modellbildung als relevante Teilbereiche einer zeitgemässen, am Subjekt orientierten, gleichermassen ästhetisch-künstlerisch und technisch-informatisch geprägten Medienbildung aufgewiesen, ihre pädagogischen Vorläufer, Forschungsprojekte und Nachbardisziplinen benannt sowie Ausblicke für eine zeitgemässe Medienbildung gegeben.

    CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) uses CaWO{sub 4} single crystals as targets for the direct search for dark matter particles. Since several years these CaWO{sub 4} crystals are grown at the Technische Universitaet Muenchen. Thereby, commercially available CaCO{sub 3} and WO{sub 3} powders are used for the synthesis of CaWO{sub 4} powder. For the experiment low intrinsic contaminations of the crystals play a crucial role. In order to improve the radiopurity of the crystals it is necessary to reduce potential sources for radioactive backgrounds such as U and Th. In this poster we will present our studies of the chemical purification of the CaCO{sub 3} and CaWO{sub 4} powders.

    Natural bentonites are an important material in the casting industry. Smectites as the main component of bentonites plasticize and stabilise sand moulds. Pore water as well as interlayer water within the smectites are lost as a function of time, location and temperature. Although rehydration of the smectites should be a reversible process, the industrially dehydrated smectites lose their capability to reabsorb water. This limits the number of possible process cycles of the mould material. A full understanding of the dehydration process would help to optimise the amount of fresh material to be added and thus save resources. A simulated metal casting was investigated with neutron radiography at the ANTARES neutron imaging facility of the FRM II reactor of Technische Universitaet Muenchen, Germany.

    The new research reactor FRM-II of the Technische Universitaet Muenchen (TUM) has been designed to provide a maximal thermal neutron flux at mere 20 MW power. The single element design uses silicide fuel of densities 3.0 and 1.5 g/cm 3 of highly enriched uranium (HEU, 93 % U-235). With the nuclear license, that was granted in May 2003, a condition was imposed to reduce the enrichment of FRM-II to medium enriched uranium (MEU) with not more than 50 % U-235 until the end of the year 2010. The TUM has established an international working group to meet this target. This paper presents the backgrounds and the results and plannings for the first of three 2 1/2 year periods to reach the conversion in time. (author)

    This work quantifies aluminium in thin surface and near surface layers. In one example, the layer overlies a thin gallium nitride layer on an aluminium oxide substrate and in a second example the aluminium exists just below the surface of an indium arsenide substrate. The technique of non-Rutherford elastic backscattering of protons was used for the samples where aluminum in the layer of interest needed to be resolved from aluminium in the sapphire substrate and the results were corroborated at the Technische Universitaet Muenchen using heavy ion elastic recoil detection analysis. In the second example, where it was unnecessary to isolate the signal of aluminium in the layer of interest (as the substrate contained no aluminium), then the 27 Al(d,p 01 ) 28 Al nuclear reaction was used. The elastic proton scattering cross section of aluminum was found to vary very rapidly over the energy range of interest

    2015-07-01

    The neutron lifetime τ{sub n}=880.3±1.1 s is an important parameter in the Standard Model of particle physics and in Big Bang cosmology. Several systematic corrections of previously published results reduced the PDG world average by several σ in the last years and call for a new experiment with complementary systematics. The experiment PENeLOPE, currently under construction at the Physik-Department of Technische Universitaet Muenchen, aims to determine the neutron lifetime with a precision of 0.1 s. It will trap ultra-cold neutrons in a magneto-gravitational trap using a large superconducting magnet and will measure their lifetime by both neutron counting and online proton detection. This presentation gives an overview over the latest developments of the experiment.

    An outline of the history and duties of the Physikalisch-Technische Bundesanstalt (PTB) is to illustrate that the new duties of the PTB in connection with radioactive substance safeguarding and ultimate storage fit in very well with the range of duties of the PTB. The organisatory and technical accomplishment of these duties in cooperation with a building and operating company and with industry is explained. The department of the PTB for the 'safeguarding and ultimate storage of radioactive wastes' has an examining, appraising and licensing function in connection with construction, operation and shutdown of safety facilities. Methods for the safeguarding and ultimate storage of all the radioactive wastes in the Federal Republic of Germany are described. (HS) [de

    This contribution first deals with the duality of mercantile and technical plant management systems. The following aspects are considered: reasons for and history of this duality; different approaches taken by mercantile and technical plant management systems; differences in the standardisability of mercantile and technical tasks. Dissolution of the duality through coordinated interplay. The author then goes on to explain the most important components of technically oriented maintenance management. These include the collection of technical plant data (with maintenance-relevant data and relations); the establishment of recurring tasks, the commissioning method (involving occupational safety, packaging and evaluation), compilation of manuals, reporting and accompanying plant documentation. The following tools are useful for DP-assisted maintenance: depiction of organisational and operational structures (authorisation system + IBFS application); workflow systems; modelling (data and object models); navigators; form and dialogue generators; integration of external software (project planning, CAD and Office); interface to mercantile systems. Some highlights of the C/S-IBFS were demonstrated in practice at the symposium.

The methodology includes patient-relevant data, examination data, imaging techniques and biochemical tests. Clinically important differences were found for papillary and follicular thyroid carcinoma. Further differences concern the localization of metastases. The author discusses the prognostic significance of the primary tumor radius in comparison with the so-called TNM classification for papillary and follicular thyroid carcinomas. It is concluded that the new version of the TNM classification offers only slight advantages with respect to the former version. It was also shown that the primary tumor size is adequate for prognostic estimations.

    There is a growing trend towards using calculation programmes to design and optimise technical systems. Such programmes simulate the systems' dynamic behaviour on the basis of mathematical models. This book first presents the methods used for model identification and model description. A widely applicable basic algorithm has been derived by means of these methods. Creating an overview block diagram of the system under study constitutes an important step of model development. The methods elaborated by the author are applied to numerous examples ordered in a sequence of growing complexity and hence difficulty. The examples each end with calculations on the model's behaviour, the results of which the reader can verify. Using the applied basic algorithm as a basis the reader can efficiently examine other systems not addressed in the book. [German] Technische Systeme werden immer staerker mit Hilfe von Rechnerprogrammen entworfen und optimiert. Die Programme simulieren das dynamische Verhalten der Systeme auf der Basis von mathematischen Modellen. In diesem Buch wird zunaechst die Methodik der Modellermittlung und -beschreibung dargelegt, aus welcher ein breit anwendbarer Grundalgorithmus abgeleitet worden ist. Eine wichtige Stufe der Modellentwicklung ist das Gesamt-Blockschaltbild des untersuchten Systems. Die vom Autor erarbeitete Methodik wird auf zahlreiche Beispiele wachsender Komplexitaet und damit wachsenden Schwierigkeitsgrades angewendet. Diese Beispiele enden mit Berechnungen des Verhaltens dieser Modelle, deren Ergebnisse der Leser nachpruefen kann. Der Leser kann auf der Grundlage des angewendeten Grundalgorithmus zielstrebig andere, im Buch nicht behandelte, Systeme untersuchen. (orig.)

    Therapy dosemeters are subject to calibration as from January 1, 1983 according to section 3 of the second ordinance concerning the obligation to calibrate measuring instruments (in the version of the ordinance concerning the amendment of the second and third ordinance about the obligation to calibrate measuring instruments of December 21, 1979, Federal Gazette I p 2347). Section 4 subsection 2 of this ordinance determines a transitional period until December 31, 1985. In this transitional period those therapy dosemeters may be used without calibration which were already in use on January 1, 1983. The requirements of the PTB correspond to the established rules of technology. They specify and complete the provisions of the standardization regulations and establish terms and conditions of the test. They passed the general assembly of the Physikalisch-Technische Bundesanstalt concerning calibration and measurement of 1982. The requirements of the PTB stipulate the admissible limits for effects of numerous influencing factors and other properties of the equipment and tolerances of calibration and handling. (orig.) [de

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

    With technical improvements in gradient hardware and the implementation of innovative k-space sampling techniques, such as parallel imaging, the feasibility of pulmonary perfusion MRI could be demonstrated in several studies. Dynamic contrast-enhanced 3D gradient echo sequences as used for time-resolved MR angiography have been established as the preferred pulse sequences for lung perfusion MRI. With these techniques perfusion of the entire lung can be visualized with a sufficiently high temporal and spatial resolution. In several trials in patients with acute pulmonary embolism, pulmonary hypertension and airway diseases, the clinical benefit and good correlation with perfusion scintigraphy have been demonstrated. The following review article describes the technical prerequisites, current post-processing techniques and the clinical indications for MR pulmonary perfusion imaging using MRI. (orig.)

    A qualitative and a quantitative study on the title subject were carried out. The quantitative study is based on the third measurement of the multi-client study in which attention is paid to attitudes (and use) of energy en the interest for domotica. The results are correlated with different types of communities. In the qualitative study attention is paid to motives to purchase domotica applications. [Dutch] Het programma DEMOS heeft in 2001 een aantal strategische studies uitgezet die elk een aspect van domotica en technische gedragsturing nader analyseren.

    The goal of the research project is to examine the complexation behaviour of actinide ions with humic substances and thermodynamically describe the binding based upon a simple complexation model. This program is a continuation of the activities of the colloid and complexation group (COCO) in the second phase of the EC-MIRAGE project. A number of different experimental methods are used to determine speciation. The metal ions examined are the trivalent lanthanides, UO 2 2+ , NpO 2 + , Am 3+ , and Cm 3+ . The project is divided into three tasks: Task 1: complexation reactions of actinide ions with well characterized reference and site-specific humic and fulvic acids, Task 2: complexation reactions with major cations in natural groundwaters; Task 3: validation of the complexation data in natural aquatic systems by comparison of calculation with spectroscopic experiment. Five European community laboratories participated in the program: Technische Universitaet Muenchen, Commissariat a l'Energie Atomique Fontenay-Aux-Roses and Saclay, Universitaet Mainz, Katolieke Universiteit Leuven, and Joint Research Centre, Ispra. The evaluated stability constants are similar for all laboratories when the same humic substance complexation model is applied. Humic acid is shown to reduce NpO 2 + to Np 4+ , while no reduction of UO 2 2+ is observed. Temperature effects are seen on the Np humate complex. Competition is observed between NpO 2 + and Ca 2+ , but not between the trivalent lanthanides and Ca 2+ . No influence of humic acid purification on the evaluated stability constants is seen. Using the evaluated constants, calculations are conducted for natural water systems which indicate the trivalent actinide humate complex to be an important species. (orig.)

    In hoch entwickelten Industrieländern stehen laut Weltgesundheitsorganisation (WHO) Herz-Kreislauf-Erkrankungen und speziell die Koronare Herzkrankheit (KHK) an erster Stelle der Todesursachen. In Deutschland betrug die Zahl der erfassten, an KHK erkrankten Personen ohne Berücksichtigung der Dunkelziffer allein im Jahre 2001 über 473.000. Die KHK war im Jahre 2003 mit 92.673 erfassten Todesfällen immer noch die häufigste Todesursache, obgleich in Deutschland die Häufigkeit der Koronarinterventionen zur Behandlung der KHK zwischen 1984 und 2003 um fast das 80fache von 2.809 auf 221.867 Eingriffe pro Jahr gestiegen ist [1]. Neben der hohen Zahl an Todesfällen haben die betroffenen Personen durch chronische Schmerzen und eingeschränkte körperliche Leistungsfähigkeit zusätzlich eine starke Beeinträchtigung der Lebensqualität [2].In Folge dessen wird die erkrankte Person häufig zum Pflegefall was neben den gesundheitlichen Aspekten auch eine sozioökonomische Komponente in Form der fehlenden Arbeitskraft und den auftretenden Pflegekosten nach sich zieht. Die Kosten für die Behandlung der KHK in Deutschland beliefen sich im Jahre 2002 laut Statistischem Bundesamt auf rund 6,9 Mrd. €. Verglichen mit ähnlichen Zahlen der USA dürfte sich der entstandene Schaden für die deutsche Volkswirtschaft im zwei- bis dreistelligen Milliardenbereich bewegen [3].

    The direct dark matter search experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) uses scintillating CaWO{sub 4} single crystals as targets for possible recoils of dark matter particles. Since several years these CaWO{sub 4} crystals are produced directly at the Technische Universitaet Muenchen (TUM) including the CaWO{sub 4} powder production from the raw materials CaCO{sub 3} and WO{sub 3}, the CaWO{sub 4} crystal growth via the Czochralski method as well as the after-growth treatment of the crystals. In the recently finished CRESST-II Phase 2 (2013-2015), 4 TUM-grown crystals were installed in the main cryostat for the first time. Showing one of the best radiopurities of all installed crystals combined with an excellent detector performance the analysis of the crystal TUM40 resulted in the best sensitivity for low-mass dark matter particles in 2014. For the upcoming CRESST-III phase 2 we aim for a further improvement in radiopurity by a factor of 100. First results of a chemical purification of the raw materials as well as future plans to reduce the intrinsic background via recrystallization are presented.

    Although neutron lifetime plays an important role in the Standard Model of particle physics, τ{sub n} is not very precisely know and often discussed. The official PDG mean value has been lowered during the last years by more than 6σ to the new value of 880.3 ± 1.1 s. The new precision experiment PENeLOPE, which is currently developed at Technische Universitaet Muenchen, will help to clear this up. Ultra-cold neutrons are lossless stored in a magneto-gravitational trap, formed by superconducting coils. The combined determination of τ{sub n} by counting the surviving neutrons after each storage cycle on one side and in-situ detection of the decay protons on the other side together with a very good handle on systematic errors leads to an unprecedented precision of the neutron lifetime value of 0.1s. This contribution will give an overview of the challenges concerning proton detection under the exceptional requirements of this experiment. The developed concept of using avalanche photodiodes for direct proton detection will be presented as well as results from first measurements with a prototype detector read out by particular developed electronics.

    Since the first observation of geomagnetically trapped antiprotons by the PAMELA experiment and the new results on the positron excess by the AMS-02 experiment, the creation and transport of antimatter in the Earth's upper atmosphere attracts more and more attention both at theoretical and experimental side. For this reason the AFIS experiment was initiated to measure the flux of low energetic antiprotons in the South Atlantic Anomaly (SAA). We developed an active target detector made from scintillating fibers connected to silicon photomultipliers which allows to detect antiprotons in the energy interval of about 30 MeV-100 MeV. The stopping curve of incoming antiprotons (Bragg peak) and the signal of outgoing pions created from the annihilation, are used for particle identification as well as triggering. We plan to implement this detector on a 3 unit cubesat satellite in the framework the 'Move2Warp' mission, which is carried out as a student project by the Technische Universitaet Muenchen.

    High-energy cosmic rays interact with Earth's upper atmosphere and produce antiprotons, which can be trapped in Earth's magnetic field. The Antiproton Flux in Space (AFIS) Mission will measure the flux of trapped antiprotons with energies less than 100 MeV aboard the nanosatellite MOVE 2. An active-target tracking detector comprised of scintillating plastic fibers and silicon photomultipliers is already under construction at the Technische Universitaet Muenchen. As a precursor to the space-bound mission, a prototype version of the detector will be launched aboard a balloon from Kiruna, Sweden as part of the REXUS/BEXUS student program by the German Aerospace Center (DLR). Named AFIS-P, it will be used to measure the low-energy part of the cosmic-ray spectrum for energies less than 100 MeV-per-nucleon. Spectrometers in previous balloon missions were not sensitive in this low-energy region. Thus AFIS-P will deliver unprecedented data, while simultaneously allowing us to field-test the AFIS detector.

    High-pressure entrained flow coal gasification is becoming increasingly important particularly in the development of Integrated Coal Gasification Combined Cycle (IGCC) technology for the production of electricity. However, there is a lack of knowledge worldwide for the gasification process and more especially for the chemical reactions (reactions rates) that take place under high pressure and temperature. Therefore a gasifier has been designed and is being built at the Institute for Energy Systems (Lehrstuhl fuer Energisysteme - LES) at the Technische Universitaet Muenchen (TUM). This gasifier is an entrained flow gasifier and has the advantage that it can operate to very high conditions of pressure and temperature, up to 50 bar pressure and 1800{sup o}C temperature. In an ongoing project, a great variety of experiments are planned to determine chemical reactions rates at high pressure conditions. In addition to the experimental work, CFD numerical simulations of pulverized coal gasification are being performed. The aim is to use numerical investigations for preliminary assessment of the facility. The goal is to develop a gasification model suitable for high pressure and condition tailored on the experiments to be used in CFD computations to predict chemical reactions, the heat transfer and the turbulence inside the gasifier. 9 refs., 2 figs., 2 tabs.

    Optimisation and development of technical combustion systems in order to generate energy efficiently and reduce pollution is an ever-increasing challenge. Mathematical and numerical simulations play a very important role in this context. This project was dedicated to the implementation and improvement of mathematical models and subsequent verification of the modelling concepts. Verification used data measured by the university department for combined cyle turbines. The focal point of interest was the reaction zone near the burner. Further points of interest: development and improvement of models for two-phase effects, fuel consumption and turbulence interaction as well as further development of the methods of numerical simulation. Simulating the combustion chamber of the combined cycle turbines was prioritised.(orig.) [German] Die Optimierung und Weiterentwicklung technischer Verbrennungssysteme mit dem Ziel einer moeglichst effizienten und schadstoffarmen Energiebereitstellung stellt eine staendig wachsende Herausforderung dar. Bei der technologischen Umsetzung dieses Ziels kommt der mathematisch-numerischen Simulation eine immer groessere Bedeutung zu. In diesem Projekt sollte die Implementierung und Verbesserung von mathematischen Modellierungsansaetzen sowie die anschliessende Verifikation der Modellierungskonzepte anhand der Messdaten des Lehrstuhls fuer Dampf- und Gasturbinen (LDuG) durchgefuehrt werden. Der Schwerpunkt lag in der brennernahen Reaktionszone. Konkrete Arbeitsschwerpunkte waren die Weiterentwicklung und Verbesserung der Modellansaetze fuer Zweiphaseneffekte, Brennstoffumsatz und Turbulenzinteraktion sowie die Weiterentwicklung der Methodik der numerischen Simulation. Dabei stand die Simulation der Brennkammer des LDuG im Vordergrund. (orig.)

    Efficient storage of electrical energy is an increasing need. New developments in high-power electronics, high-strength materials and magnetic bearings have made efficient reliable flywheel mass storage systems in the range of 1-5 MfW/50-150 kWh conceivable. According to a first assessment, these systems may provide energy to the supply grid in a range of seconds and thus ensure frequency maintenance and compensation of short interruptions. The authors present first results of a preliminary study preparatory to a feasibility study on the technical and economic practicability of flywheel mass storage systems. (orig.) [Deutsch] Das Thema effiziente Speicherung von elektrischer Energie gewinnt immer mehr an Bedeutung. Durch neuere Entwicklungen in der Leistungselektronik und bei der Herstellung hochfester Werkstoffe sowie durch Fortschritte bei der Entwicklung von beruehrungsfreien Lagern im Bereich der aktiven Magnetlager (AML) und insbesondere supraleitenden Magnetlager (SML) sind effiziente und sichere Schwungmassenspeicher-Systeme (SMSS) bis in die Bereiche 1-5 MW/50-150 kWh denkbar. Nach einer ersten Einschaetzung eignen sich solche Anlagen, um im Sekundenbereich Energie in das Netz abzugeben und somit zur Frequenzstuetzung und zur Kompensation von Kurzunterbrechungen beizutragen. Praesentiert werden erste Ergebnisse einer Untersuchung zur Vorbereitung einer Machbarkeitsstudie ueber die technisch-wirtschaftliche Realisierbarkeit von Schwungmassenspeicher-Systemen. (orig.)

    ook relatieve vochtigheid en CO2. Een 'representatieve' tuinder of een tuinder met een 'gemiddelde' energiebehoefte is daarom moeilijk vast te stellen. Voor elke situatie geldt een eigen economische rentabiliteit. De uitkomsten van deze studie kunnen daarom niet zonder meer worden overgenomen voor andere projecten. Technisch is er veel mogelijk, zo blijkt uit de ingediende offertes. Van de zestien leveranciers bieden er drie een vergasser met warmtekrachtkoppeling (WKK) aan die, onder bepaalde randvoorwaarden, naast hout tevens laagwaardige reststromen aankan. Het voordeel van laagwaardige reststromen zoals bermgras, riet en miscanthus is een gunstigere prijs ten opzichte van hout. Een lage biomassaprijs heeft een positief effect op de exploitatiekosten, en daarmee op de economische rentabiliteit van de relatief kostbare installaties. De investering voor een complete vergasserWKK-installatie ligt 5 tot 10 keer hoger dan die voor een gangbare gasWKK-installatie. Ook het CO2 -gebruik heeft invloed op de economische rentabiliteit. De inkoop van CO2 is een kostbare aangelegenheid. Onderzocht is of er zowel technisch als economisch beschikbare CO2 -winning uit rookgas mogelijk is. Hiervoor zijn twee CO2 -winninginstallaties bekeken: die van Procede en Knook. Voor een vergasser-WKK-installatie met relatief klein vermogen (tot 800 kWe) is CO2-winning volgens zowel Procede als Knook economisch niet rendabel. CO2 -inkoop of -opwekking middels de bestaande aardgasgestookte ketel ligt daarom meer voor de hand. Uit de technisch-economische haalbaarheidsstudie blijkt dat door de relatief hoge investerings- en onderhoudskosten, investeren in een vergasserWKK-installatie niet rendabel is. CO2 -behoefte en de onzekerheid van de biomassaprijzen spelen daarbij parten. Maar met subsidie op duurzame energieproductie (SDE+) en subsidies op investering zoals MEI en EIA ontstaat een ander beeld. Uitgaande van de goedkopere 800 kWe installaties, een SDE+ vergoeding van 90

    Within the POOLTHY Project of the European Union (Euratom Fourth Framework Programme contract FJ4J-CT95-0003) an active/passive concept (SUCO-Programme) was investigated which controls the heat removal after a potential core melt-down accident in an evolutionary light water reactor by spreading and stabilising the core melt in the reactor sump and flooding the melt with sump water from above. The experiments were performed in the test facility SUCOT which was designed and erected at the Institute for Nuclear and Energy Technologies (IKET). The report gives an overview on the SUCO-Programme and the scaling analysis, which was applied to design the test facility SUCOT. A detailed technical description of the test facility SUCOT is given, in which the natural circulation driven two-phase flow within the reactor sump and relevant phenomena such as flow boiling, disperse bubbly flow with and without mass transfer, and geysering are investigated. The major components of the test facility, the three-loop system and the instrumentation are described. Finally, a perspective for future application of the gained knowledge is given. (orig.)

    2015-05-01

    To overcome the challenge of helicopter flight in degraded visual environments, current research considers headmounted displays with 3D-conformal (scene-linked) visual cues as most promising display technology. For pilot-in-theloop simulations with HMDs, a highly accurate registration of the augmented visual system is required. In rotorcraft flight simulators the outside visual cues are usually provided by a dome projection system, since a wide field-of-view (e.g. horizontally > 200° and vertically > 80°) is required, which can hardly be achieved with collimated viewing systems. But optical see-through HMDs do mostly not have an equivalent focus compared to the distance of the pilot's eye-point position to the curved screen, which is also dependant on head motion. Hence, a dynamic vergence correction has been implemented to avoid binocular disparity. In addition, the parallax error induced by even small translational head motions is corrected with a head-tracking system to be adjusted onto the projected screen. For this purpose, two options are presented. The correction can be achieved by rendering the view with yaw and pitch offset angles dependent on the deviating head position from the design eye-point of the spherical projection system. Furthermore, it can be solved by implementing a dynamic eye-point in the multi-channel projection system for the outside visual cues. Both options have been investigated for the integration of a binocular HMD into the Rotorcraft Simulation Environment (ROSIE) at the Technische Universitaet Muenchen. Pros and cons of both possibilities with regard on integration issues and usability in flight simulations will be discussed.

    Funded by the DFG (German Research Foundation) and some industry partners like GM Powertrain Europe, ZF, EPCOS the Optimised CVT-Hybrid was developed at Technische Universitaet Muenchen in close collaboration with the industry and is currently under scientific investigation. Designed as a parallel hybrid vehicle the Optimised CVT-Hybrid combines a series-production diesel engine with a small electric motor. The core element of the driveline is a two range continuously variable transmission (i{radical}i-transmission), which is based on a chain variator. By a special shifting process without interruption of traction force the ratio range of the chain variator is used twice; thereby a wide transmission-ratio spread is achieved by low complexity. Thus the transmission provides a large pull-away ratio for the small electric motor and a fuel-efficient overdrive ratio for the ic-engine. Instead of heavy and space-consuming accumulators a small efficient package of double layer capacitors (UltraCaps) is used for electric energy and power storage. The driveline management is done by an optimised vehicle controller. Within the scope of the research project two prototype drivelines were manufactured. One driveline is integrated into an Opel Vectra Caravan and is available for investigations at the roller dynamometer and in the actual road traffic. The second hybrid driveline is assembled at the powertrain test rig of the FZG for detailed analysis of system behaviour and fuel consumption. Based on measurements of standardised driving cycles system behaviour, fuel consumption and a detailed energy balance of the Optimised CVT-Hybrid are presented. In comparison to the series-production vehicle the fuel savings are shown. (orig.)

  1. Clinical utility of 18-FDG-PET with a modified SPECT-camera using molecular coincidence detection in oncology

    Malignant diseases are belonging to one of the most frequent reasons for mortality and morbidity of people in industrialized countries. In order to avoid inadequate therapy such as unnecessary operations etc. accurate diagnostic techniques are needed to assess malignancy of proven lesions, for staging of cancer or to assess success of therapy. Many studies have reported the value of PET in such cases. Because of limited financial resources we started PET with a Dual-head-SPECT-camera modified with a MCD-module in February 1997 in order to obtain quick access to clinical 18-FDG studies. The aim of this work was to compare the results of our system with reports of the so called 'state of the art'-PET and with other diagnostic techniques used in clinical oncology. So far 124 studies were performed with the MCD-mode using a standardized investigation protocol between February 1997 and May 1998. The applied dose of 18-FDG for oncological studies was about 185 MBq. The tracer was supplied from the radio-pharmaceutical unit of the Department of Nuclear Medicine, Klinikum Rechts der Isar, Technische Universitaet Muenchen. The obtained results were carefully compared with CT, MRI and conventional radiology. In addition, the final diagnosis (based on histology, surgical reports, autopsy and follow up) was also considered. Oncological studies were done either to assess malignancy in certain lesions (n = 25), for staging cancer (n = 77), or to assess success of therapy (n = 22).

    Having found numerous biogas-(co)generation plants exceeding the formaldehyde emission limits given in German Technical Instructions on Air Quality Control (TA Luft), the mechanisms of in-engine formation of formaldehyde were investigated at the Institute of Internal Combustion Engines (LVK) of the Technische Universitaet Muenchen in collaboration with the German Forschungsvereinigung Verbrennungskraftmaschinen e.V (FVV, Research Association for Combustion Engines; research project No. 918). In these investigations the potential for reducing formaldehyde emissions with in-engine measures was found to be limited unless deteriorations in engine efficiency and nitric oxides' emissions are accepted. As a result, after- treatment of the exhaust gases is necessary, especially with respect to the tightening of the formaldehyde limits in January 2009. To get information about the yet unknown long-term behaviour of exhaust-gas after-treatment on biogas plants, a further project was launched. Within half a year emissions of formaldehyde and methane, the latter of them with regard to its global warming potential, were investigated at two biogas plants equipped with two different technologies of after-treatment. These investigations proved regenerative thermal oxidation (RTO) as well as catalytic oxidation (Oxi-Kat) capable for reducing the emissions of formaldehyde below valid limits, though further research has to be conducted to improve the durability of the Oxi-Kat as well as the performance of the RTO in non-steady-state operation, especially cold start. Emissions of methane were effectively reduced with the RTO whereas the Oxi-Kat, which in fact was optimized for reducing emissions of formaldehyde, only had a negligible effect on it. It is expected that further research on catalytic coatings will improve the Oxi-Kat's performance in methane-oxidation. This project was sponsored by the Federal Ministry for the Environment, Nature Conservation and Reactor Safety

    2001-01-01

    The new high flux research reactor of the Technical University of Munich (Technische Universitaet Muenchen, TUM) will be equipped with a cold neutron source (CNS). The centre of the CNS will be located in the D2O-reflector tank at 400 mm from the reactor core axis, close to the thermal neutron flux maximum. The power of 4500 W developed by the nuclear heating in the 16 litres of liquid deuterium at 25 K, and in the structures, is evacuated by a two phase thermal siphon avoiding film boiling and flooding. The thermal siphon is a single tube with counter current flow. It is inclined by 10 from vertical, and optimised for a deuterium flow rate of 14 g/s. Optimisation of structure design and material, as well as safety aspects will be discussed. Those parts of the structure, which are exposed to high thermal neutron flux, are made from Zircaloy 4 and 6061T6 aluminium. Structure failure due to embrittlement of the structure material under high rapid neutron flux is very improbable during the life time of the CNS (30 years). Double, in pile even triple, containment with inert gas liner guarantees lack of explosion risk and of tritium contamination to the environment. Adding a few percent of hydrogen (H2) to the deuterium (D2) will improve the moderating properties of our relatively small moderator volume. Nearly all of the hydrogen is bound in the form of HD molecules. A long term change of the hydrogen content in the deuterium is avoided be storing the mixture not in a gas buffer volume but as a metal hydride at low pressure. The metal hydride storage system contains two getter beds, one with 250 kg of LaCo3Ni2, the other one with 150 kg of ZrCo(0.8)Ni(0.2). Each bed can take the total gas inventory, both beds together can absorb the total gas inventory in less than 6 minutes at a pressure < 3 bar. (orig.)

The latter will take place in the horizontal beam tube SR4, which will house an additional cryogenic moderator (e.g. solid deuterium). More than 60% of the experiments foreseen in the new neutron research facility will use cold neutrons from the CNS. The mounting of the hardware components of the CNS into the reactor has started in the spring of 2000. The CNS will go into trial operation in the end of year 2000. (J.P.N.)

    This work is concerned with the investigation of inhomogeneities in materials with length scales of the order of micrometers by means of neutrons. In real space this is done by neutron imaging methods measuring the transmitted signal while for Ultra Small Angle Neutron Scattering (USANS) the signal of the scattered neutrons is assigned to a spatial frequency distribution in reciprocal space. The part about neutron imaging is focused on time-resolved neutron radiography on an injection nozzle similar to the ones used for modern diesel truck engines. The associated experiments have been carried out at the neutron imaging facility ANTARES at the Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II) of the Technische Universitaet Muenchen in Garching near Munich. Especially the demands on the detector system were high. Therefore different detection methods and detector configurations have been tested. On the one hand the detector should allow for a time resolution high enough to record the injection process lasting about 900 μs. On the other hand it needed to offer a spatial resolution sufficient to resolve the test oil inside the spray hole of a maximum diameter of less than 200 μm. An advanced aim of this work is the visualization of cavitation phenomena which may occur during the injection process inside of the spray hole. In order to operate the injector at conditions as close to reality as possible a high pressure pump supplying the injector with test oil at a pressure of 1600 bar was needed in addition to the specially developed control electronics, the recuperation tank and the exhaust gas equipment for the escaping atomized spray. A second part of the work describes USANS experiments based on the idea of Dr. Roland Gaehler and carried out at the instrument D11 at the Institut Laue-Langevin in Grenoble. For this purpose a specific multi-beam geometry was applied, where a multi-slit aperture replaced the standard source aperture and the sample aperture was

    This final report describes the results of the techno-economic accompanying research of the competition of bioenergy regions. The competition was realized as a three-year funding project of the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), wherein the DBFZ analyzed the bioenergy development in the project regions and effects for regional development. The aim of the techno-economic accompanying research was to evaluate the project regions regarding the use of bioenergy. To this end, the bioenergy plants and supply chains of bioenergy as well as the raw materials used were the focus of investigations. Hereby the comparison between the regions and classification of the national average should be made possible. It was also necessary to be able to make statements about the climate protection contribution of funding the project. Not least the DBFZ supported the office of competition and the regions in answering technical-economic issues. The report is divided into a theoretical part A and the result Part B. After a summary of the results (chapter 1) and a brief overview of important and higher-level indicators (Chapter 2) the background and objectives of the competition are in Part A, first presented (Chapter 3). This is followed by Chapter 4 of the explanation of the methodological approach. Part B contains the results of the accompanying research project. The individual chapters are based respectively on the specific questions or thematic blocks of techno-economic accompanying research (Section 5-8). The final chapter 9 takes a brief look at the second funding phase from 2012 to 2015.

    Different oil condensing boilers, which were available on the German market, have been investigated in order to determine the relevant limit for sulphur content in domestic heating oil. Up to now, the condensate from oil condensing boilers has to be neutralized in many cases due to local legislation. The composition of the condensates from oil boilers came out to be similar to the condensate from gas condensing boilers, as long as the sulphur content of heating oil is below 100 mg/kg. As the neutralization of condensate from gas condensing boilers is usually not required up to 200 kW-boilers, there should be no technical reason for neutralization, as long as the sulphur content is below 100 mg/kg. However, boiler manufactures are convinced, that only if the sulphur content is as low as 50 mg/kg, it will be possible to develop reliable oil condensing boilers for a reasonable price. Calculations of the total energy consumption came to the result, that primary energy can be saved. The increase of efficiency on the boiler side has more influence than the energy needed for desulphurization. (orig.)

Zur Zeit wird durch das ATV Arbeitsblatt A-251 eine Neutralisation von Kondensaten aus Oelbrennwertanlagen gefordert. Die Untersuchungen zeigen, dass bei Schwefelgehalten unter 100 mg/kg die Kondensate aehnliche Zusammensetzungen aufweisen wie Kondensate aus Gasbrennwertgeraeten. Die Voraussetzung fuer eine Befreiung von der Neutralisationsverpflichtung bei der Verwendung dieser Brennstoffe ist damit aus technischer Sicht gegeben. Fuer die Entwicklung von neuen, kompakten und preiswerten Oelbrennwertgeraeten wird von der Heizgeraeteindustrie ein Schwefelgehalt von max. 50 mg/kg fuer notwendig gehalten

A retrospective analysis of patients treated with radio(chemo)therapy between 1988 and 2011 at Klinikum rechts der Isar, Technische Universitaet Muenchen was performed. In all, 168 patients received radio(chemo)therapy for ESCC in curative intention. The median follow-up time was 91 months (range 1-212 months). There were 128 men and 40 women with a median age of 63 years. Selection criteria for radio(chemo)therapy were unfit for surgery and/or unresectable primary tumor (n = 146, 87 %) or patients' choice (n = 22, 13 %). The majority of the patients received a combination of cisplatin and 5-fluorouracil chemotherapy with 54 Gy in 30 fractions of radiotherapy. The median overall survival (OS) was 20 months (95 % confidence interval 17-23 months). The OS at 2 and 5 years for the whole cohort was 41 ± 4 % and 22 ± 3 %, respectively. Forty patients (24 %) suffered an in-field recurrence. The most common acute nonhematologic toxicity >grade 2 was dysphagia in 35 % of the patients. Acute hematologic toxicity > grade 2 was recorded in 14 % of the patients. There was no grade 5 toxicity observed during the study. Poor ECOG performance status (0-1 vs. 2-3, HR = 1.70, p = 0.002) and weight loss ≥ 10 % before the start of therapy (HR = 1.99, p = 0.001) were among the factors significantly associated with poor OS in multivariate analysis. Three-dimensional conformal definitive radio(chemo)therapy is well tolerated and leads to long-term survival in more than 20 % of patients with advanced disease and/or contraindication to surgery. However, 24 % in-field recurrence remains a major concern. Prospective trials are warranted to assess if a well-tailored conformal radiochemotherapy can improve the local control and obviate the need for surgical resection in patients with good general

    The change of the individual mobility on environmentally friendly and sustainable approach is not only in Germany an important concern, but also a global challenge. The main reasons for an involvement are dwindling crude oil reserves and the greenhouse effect. Due to the road traffic as one of the largest emitters of CO{sub 2} possibilities are discussed to make mobility more environmentally friendly and energy-politically sustainable. In this context, the electric car is seen as a possible component of the vision for the future of the environment and mobility. The contribution under consideration reports on the possible development of electric vehicles in Munich in 2030 based on three scenarios. The results are based on a fundamental study of the Institute fortiss GmbH (Munich, Federal Republic of Germany) and a recent study by the Research center for Energy Economics (Munich, Federal Republic of Germany) for electric vehicles.

    Schwebstoffen, die in 20 zumeist Landesinstitutionen z. T. im Zeitraum von 1984-2002 erhoben worden waren, wurde der Versuch unternommen, die Belastungshoehen und Stoffmusterprofile fuer Probenahmelokalitaeten am Rhein und Fluessen in BW, Hess, RP und NRW kenntlich zu machen. Die untersuchten Verbindungen waren die isomeren Di-, Tri- und Tetrachlorbenzene, Penta- und Hexachlorbenzen, Ochtachlorstyren (OCS), Hexachlorbutadien (HCBD) sowie die 6 DIN-(IUPAC-, Ballschmiter)Kongenere der PCB, Substanzen, die zumeist im Sinne von REACH als PBT-, z. T. als vPvB-Stoffe bezeichnet wurden bzw. als ''prioritaer gefaehrliche Stoffe'' (PCBz, HCB, HCBD) eingestuft sind. Die statistisch verrechneten Einzeldaten wurden zu Streckenprofilen und Zeitreihen verarbeitet, mit dem Ziel, lokale oder regionale Immissionen, Hinweise zu ihrer Entstehung und gegenwaertigen Bedeutung kenntlich zu machen. Hintergrund dieser Bestrebungen ist, dass Fachpublikationen ueber technische Synthesen oder Zwangsanfall der Verbindungen nach Art, Menge und Zeitraum nicht vorliegen, was als Defizit zu betrachten ist. Besonders Tetrachlorbenzen (hauptsaechlich das 1,2,4,5-TeCBz) und das HCBD konnten als Indikatorsubstanzen fuer historische und rezente technische Synthesen chlororganischer Verbindungen sichtbar gemacht werden. Die hoeher chlorierten PCB-Kongenere Nr. 138, 153 und 180 (HPCB) erwiesen sich als ausserordentlich persistent.

    The present report is the first Technical Report within the research project ''Validation and interpretation of selected models and of the coupling of the system codes ATHLET-CD and COCOSYS'', funded by the German Federal Ministry for Economic Affairs and Energy (BMWi 1501465) and projected at the Reactor Simulation and Safety Group, Chair of Energy Systems and Energy Economics (LEE) at the Ruhr-Universitaet Bochum (RUB). This report deals with the simulation of spray phenomena with the containment code system COCOSYS, which is developed by the German Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) gGmbH. First, post-test calculations of the OECD THAI-2 tests HD-30 and HD-31 are presented. The simulation results are compared to experimental values and thereby assessed. The analysis focuses an the assessment of the simultaneous use of the COCOSYS models IVO (spray model) and FRONT (combustion model) as well as a spray entrainment model developed at RUB regarding the simulation of the phenomena related to the interaction of spray and combustion processes. The simulation results show the necessity to consider the induced turbulences. The simulation of these turbulences is performed by modifying the FRONT input parameters leading to an improvement of the simulation results. The consideration of the entrainment positively influences the simulated flow pattern. Subsequently, the simulation of the entrainment of interacting sprays, as occurring in containment spray systems, is considered. The entrainment of interacting sprays is influenced by droplet collisions and changes of the drag between the droplets and the atmosphere. For the simulation an entrainment factor, which has to be determined externally, is implemented into COCOSYS. Exemplary simulations of the OECD SETH-2 ST3 tests show, that in general the use of entrainment factors enables the calculation of alternated gas distributions.

    'Technical progress safeguards future', the guiding theme of the 1985 conference of German engineers, calls for discussion. In five lectures representatives of the subdivisions of 'VDI' issued their statements from the viewpoints of their special fields. These lectures were completed by reports on the part of the remaining VDI subdivisions, which are published together with the lectures in this volume. The complex guiding theme is meant to stimulate discussion, which should be conducted also with representatives of other sciences and the public. The volume contains a.o. contributions regarding future prospects, given certain modifications in construction engineering and user behaviour in the sector heating and air-conditioning, regarding the development of new construction techniques to protect the environment, and regarding clean air as an international concern of engineers. For these three contributions separate entries were made. Other presentations relate to: automobile production technology; energy supply as an engineering task; information, invention, innovation as stages of technical progress; progress in materials technology; noise of motor vehicles - current state and future prospects.

    The 1st Technical Report was prepared for the research project ''Validation and Interpretation of the ATHLET-CD Model Basis'' funded by the Federal Ministry of Economics and Technology (BMWi1501385) and carried out at the Chair of Energy Systems and Energy Economics at Ruhr-Universitaet Bochum (RUB). This report provides results of the simulation of the Boiling Water Reactor (BWR) experiments CORA-17 and -28 with ATHLET-CD Mod. 2.2A. The system code ATHLET-CD (Analysis of Thermal-hydraulics of Leaks and Transients - Core Degradation) is developed by the German Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) mbH. Code results are compared to measurements in order to assess and to analyze the capabilities of the current code version with regard to the modeling of BWR components. The CORA test series was carried out between the years 1987 and 1993 at the former Kernforschungszentrum Karlsruhe (KfK), now Karlsruhe Institute of Technology (KIT). The investigations provided experimental data regarding the material behavior during the early phase of core degradation in Light Water Reactors (LWR). The tests CORA17 and -28 represented a typical BWR arrangement of the fuel rod bundle and provided insights about the bundle behavior during the quenching process (CORA-17) and regarding the influence of a preoxidized bundle (CORA-28), respectively. The simulation results are analyzed and discussed in terms of the thermal bundle behavior, the zirconium oxidation in steam and the resulting hydrogen generation as well as the material relocation. In particular, the recently extended modeling capabilities of the code in terms of the relocation of BWR components like the absorber blade and the canister wall are assessed. The analysis shows that the code captures the thermal behavior in good agreement in both experiments. An even enhanced reproduction of the test CORA-28 is obtained in comparison to a calculation using the previous code version ATHLET-CD Mod

    First, the legal base of the compensatory charge is described, followed by an evaluation of its revenue systematics. Since the compensatory charge revenue does not go into the federal budget, but to a special fund, a budget evaluation follows. In the framework of a financial evaluation, the effects of imposing this charge are investigated. The differences between a political assessment and a financial evaluation of this charge are shown by giving MP statements made. According to the present situation, it is also possible to combine the various purposes of power taxation in an ingeniously contrieved manner under the aspects of finance and psychology. It follows that a power tax might still be levied at a time when the original purpose of its introduction is no longer applicable.

    2010-01-01

    Following the shortage in radioisotope availability the Technische Unversitaet Muenchen and the Belgian Institut National des Radioelements conducted a common study on the suitability of the FRM II reactor for the generation of Mo-99 as a fission product. A suitable irradiation channel was determined and neutronic calculations resulted in sufficiently high neutron flux densities to make FRM II a promising candidate for Mo-99 production. In addition the feasibility study provides thermohydraulic calculations as input for the design and integration of the additional cooling circuit into the existing heat removal systems of FRM II. The required in-house processes for a regular uranium target irradiation programme have been defined and necessary upgrades identified. Finally the required investment cost was estimated and a possible time schedule was given. (author)

    The Dortmund Low Background Facility (DLB) is a low-background gamma ray spectrometry system with an artificial overburden. The overburden of ten meters of water equivalent, in combination with a multi-layer lead castle and an active muon veto are shielding a high-purity germanium detector of 60 % relative efficiency. The background level is remarkably low compared to a conventional spectrometer system without special shielding and enables sensitivities well below 1 Bq/kg. Thus, material screening measurements as well as environmental monitoring measurements are possible on an easy-accessible location above ground at the campus of the Technische Universitaet Dortmund. The integral background count rate between 40 keV and 2700 keV is 2.528±0.004 counts/kg/min, which is comparable to systems that are situated below ground. In the talk, an overview of the current status of the DLB is given and recent developments are presented.

    Distortions caused by the neutron spectrum and scattered neutrons are major problems in fast neutron radiography and should be considered for improving the image quality. This paper puts emphasis on the removal of these image distortions and deviations for fast neutron radiography performed at the NECTAR facility of the research reactor FRM-Ⅱ in Technische Universitaet Mounchen (TUM), Germany. The NECTAR energy spectrum is analyzed and established to modify the influence caused by the neutron spectrum, and the Point Scattered Function (PScF) simulated by the Monte-Carlo program MCNPX is used to evaluate scattering effects from the object and improve image quality. Good analysis results prove the sound effects of the above two corrections. (authors)

    In the research project two passenger car air-conditioning systems were analyzed with regard to cooling capacity and efficiency. The results were compared with one another. The first system was a standard air-conditioning unit using R134a as a refrigerant. As a second system a CO{sub 2} (R744) prototype HVAC unit was used. Both units were investigated on one hand installed in a car on a dynamometer by Obrist Engineering GmbH and on the other hand installed in a calorimetric test rig by Technische Universitaet Braunschweig, Institut fuer Thermodynamik. While the tests in the calorimetric test rig showed comparable efficiencies and cooling capacities for both setups, consumption advantages were determined for the R744- air-conditioning unit installed in the vehicle by the company Obrist. With CO{sub 2} (R744) as a refrigerant for mobile air-conditioning systems an environmental friendly solution is available. (orig.)

    The mutual potential influence of geothermal duplicates and the scientific investigation of the relationship between seismic and hydraulic parameters are investigated in the joint research project 'Geothermal characterization of fractured karst limestone aquifers in the Munich metropolitan area'. Thirteen doublets and triplets being in production or sunk illustrate the great geothermal potential and provide important data on the development of a thermal-hydraulic modeling of the reservoir. 3D seismic Unterhaching, 3D structural model, hydrogeological model and a high-resolution 3D temperature model form the basis of the numerical modeling. Different seismic signatures, seismic attributes and variations in the interval velocities characterize the ground geophysically, and were interpreted under consideration of geological and hydrogeological background information as well as borehole measurements in terms of hydraulically conductive homogeneous areas. For the Munich metropolitan area, the numerical modeling is a decision aid for the future optimized and sustainable hydrothermal utilization of the Malm aquifer.

    The works in the Institute for Technical Physics (ITP) concentrated in 1982 upon the application of high current superconductivity in the fields of energy engineering and fusion. Moreover, the magnet technology for use in other fields of research and technology is advanced. Fundamental investigations on cryogenics and superconductors as well as studies go along with the technical research program. The magnetic fields of stationary and quasi-stationary fusion reactors with magnetic confinement have to be produced by superconductivity. The aim of the magnet developments in the KfK is therefore to make available the technology of superconductivity for large-scale experiments in plasma physics and the later fusion reactors, which is performed in co-operation with industry as part of the European fusion program.

    The geothermal heat exchanger transfers heat geothermal heat through the metal wall of the outer pipe to the circulating water. The clean water heats up on its way down and is then pumped up again through the insulated inner riser pipe. The heated water is used for district heating. Drilling started on 26 March 1994, and the system was commissioned on 10 November 1994. Today, it supplies heat and warm water to about 1100 apartments. During its first year of operation the Prenzlau geothermal heat exchanger, which is 2800 m deep, covered more than 20 % of the heat demand of the Prenzlau-West district heating grid. The seasonal performance factor in continuous operation of the 500 kW system is between 8 and 12 % of the weather-dependent peak load, with hourly peaks of more than 700 kW. (orig./AKF) [Deutsch] Die Erdwaermetiefensonde nutzt die Waermeuebertragung vom warmen Erdreich durch die Metallwand des Aussenrohrs zum darin zirkulierenden Wasser. Das eingeleitete saubere Wasser erwaermt sich an der aeusseren Rohrwandung auf dem Weg nach unten und wird dann im inneren waermeisolierten Steigrohr an die Oberflaeche befoerdert. Das erwaermte Waser wird in Prenzlau ueber eine Waermepumpe zu Fernwaermezwecken benutzt. Am 26.3.1994 begannen die Bohrarbeiten, und am 10.11.1994 ging die gesamte Anlage in Betrieb, die heute ca. 1100 Wohnungen mit Waerme und Warmwasser versorgt. Die Erdwaermetiefensonde Prenzlau mit einer Tiefe von 2800 m deckte in den ersten beiden Betriebsjahren ueber 20 % des Waermebedarfs des Fernwaermenetzes Prenzlau-West. Die Jahresdauerleistung der Erdwaermetiefensonde mit 500 kW liegt bei 8-12 % der witterungsbedingten Jahreshoechstlast. Die Sonde gestattet Spitzenleistungen im Stundenbereich von mehr als 700 kW.

    The fourth edition of the 'Technical regulations - district heating service connections' constitutes a completely revised version answering to the considerable developments and changes the house service sector experienced between 1975 and 1985. Analyses and practical experiences have proved to show that precision thermostats which, depending on the mode of lines and layout of the service system allow to spare central temperature control systems, still have a decisive influence on the design of district heating service stations. The revised chapter on steam line service connections focuses on problems concerning the metering of condensates and the connection of secondary water heating networks to steam lines. The reader finds an updated selection of diagrams as well as a revised appendix listing the AGFW codes of practice and recommendations, relevant DIN standards and relevant VDE/VDI recommendations.

    The actualized 14th edition covers now a further chapter on energy conversion: the structure of energy demand in Germany is discussed and patterns of energy conversion highlighted. Furtheron practical application on combustion processes, thermal power plants, carbon dioxide and power generation, heating systems and refrigerating machinery are completed. The concepts of exergy and energy are introduced by postulates instead of being constructed on the basis of certain theorems; this is to give the students easier access to the fundamental balance equations which are the basic elements in the quantitative statements of the two basic laws of thermodynamics and are indispensable for their application. The balance equations are expressed in as general a form as possible taking account also of transient processes of open systems and of the special case of steady flow processes.

    The series of lectures which forms the basis of this book and took place in the winter of 1989/90 at the ETH in Zuerich were held for the purpose of discussing the stage of development of our system of ethics in view of the extremely fast pace of technological progress and the risks which accompany it. Legal, psychological and political aspects of the problem were examined, but the emphasis was placed on ethical aspects. The effects which are examined in conventional risk analyses can be considered as a part of the ethical and social aspects involved, and in turn, the consideration of ethical and social aspects can be viewed as an extension of the conventional form of risk analysis. In any case, among risk experts, the significance of ethical and social factors is uncontested, especially as regards activities which can have far-reaching repurcussions. Some objective difficulties interfere with this goal, however: - No generally acknowledged set of ethical values exists. - Cultural influences and personal motives can interfere. - Normally a risk assessment is carried out in reference to individual facilities and within a small, clearly defined framework. Under certain circumstances, generalizations which are made for complete technological systems can lead to completely different conclusions. One contribution deals with integral views of the risks of atomic energy from an ethical and social perspective. (orig.).

    Although it is a familiar subject, biochar is highly topical. The reasons are climate protection measures and the security of resources. Both the energy-intensive primary industries, such as steel, cement- and lime plants, as well as the operators of fossil-fueled power plants, particularly coal-fired power stations, have a fundamental and economically motivated interest in climate-neutral and competitively priced energy resources. For economical causes and in relevance to the climate, the focus of biochar production should be on the use of biogenic waste material. In principle, two different methods are applied to produce biochar. One is through pyrolysis, meaning heating and devolatilization of the material under the exclusion of air, and the other one is through hydrothermal treatment of biomasses in aqueous phase under high pressure and elevated temperatures. Basically, biochar with high carbon content and a low amount of volatile matter is suitable for almost every industrial process, in which coal or coke are used as reducing agents, e.g. metallurgical processes, such as iron and steel production. In order to use biochar as a fuel, a lower level of quality is sufficient. In this case, the main aim of the thermal treatment is to increase the energy density of biomass.

This evolution of technology seemed able to explain multi-causal coherences in the genesis of technology applicably by using allegedly simple rules.

    As most of the electric utilities in Germany have decided by now to adopt the multi-utility strategy for sales promotion in the open electricity market, a questionnaire has been distributed to 1 000 households in order to find out whether product bundling or cross selling in combination with the low-interest product 'electricity' is a good strategy to enlarge the customer basis. EFOplan (Munic University) and the consulting firm Accenture have been in charge of the survey. The results show the current status of insight of household customers and their motives to change supplier, as well as the pattern of demand for product bundling. (orig./CB) [German] Da mittlerweile die meisten EVUs eine Multi-Utility-Strategie anstreben, wurde mittels einer schriftlichen Befragung von 1 000 deutschen Haushalten untersucht, ob die Vermarktung von Zusatz- bzw. Buendelprodukten in Kombination mit dem Low-Interest-Produkt Strom erfolgsversprechend ist. Die Befragung, die von EFOplan (Universitaet Muenchen) in Kooperation mit der Unternehmensberatung Accenture durchgefuehrt wurde, zeigt einerseits den aktuellen Status von Informationsstand und Wechselmotiven beim Stromkauf und andererseits die Bedarfsstruktur im Hinblick auf moegliche Buendelprodukte.

    RTARC DSS (Real Time Accident Release Consequences - Decision Support System) is a computer code developed at the VUJE Trnava, Inc. (Stubna, M. et al, 1993). The code calculations include atmospheric transport and diffusion, dose assessment, evaluation and displaying of the affected zones, evaluation of the early health effects, concentration and dose rate time dependence in the selected sites etc. The simulation of the protective measures (sheltering, iodine administration) is involved. The aim of this paper is to present the process of validation of the RTARC dispersion models. RTARC includes models for calculations of release for very short (Method Monte Carlo - MEMOC), short (Gaussian Straight-Line Model) and long distances (Puff Trajectory Model - PTM). Validation of the code RTARC was performed using the results of comparisons and experiments summarized in the Table 1.: 1.

    Three scientific and technical co-operation programmes are financed with a total budget of about 6 million EURO within the framework of the French-German initiative: - Programme 1 - SARCOPHAGUS, referring to the safety of the Chernobyl 'SARCOPHAGUS'; - Programme 2 - RADIOECOLOGY, concerning the study of the radioecological consequences of the accident; - Programme 3 - HEALTH regarding the study of health effects. At the IAEA conference in Vienna in April 1996 - 10 years after the Chernobyl accident - the French and German Environment Ministers jointly announced their co-operation initiative with the Ukraine, Belarus and Russia over scientific programmes concerning the aftermath of the Chernobyl disaster. Numerous scientific studies have been conducted in the affected republics of the former USSR with and without the participation of international organisations, but largely with insufficient real coordination. For some of the studies, results have never been publicly documented. There are still incoherent or even contradictory reports on the ecological and medical consequences of the accident. The main purpose of the French-German initiative is to assist in the collection and validation of the existing data in Ukraine, Belarus and Russia for developing a reliable and objective basis useful for the planning of counter-measures, for information of the public, and for future work. GRS supported in program 3 by SBI (Strahlenbiologisches Institut der Universitaet Muenchen) and IRSN are coordinating the projects on the Western side. The CC (Radioactive Waste and Radioecology, Department Chernobyl Center for Nuclear Safety) as Eastern coordinator is also the beneficiary.

    With the decision by the German government in 2011 to revoke the operating permission from 8 of the existing 17 German nuclear power plants, the responsibility of decommissioning and dismantling these plants has moved back into the focus of public awareness. Under the current legal conditions, the last nuclear plant will be disconnected from the grid on 31.12.2022 and this will create an enormous challenge for all the involved approving authorities, expert organisations, as well as companies involved in dismantling the plants. The development of new and efficient dismantling technologies and strategies is required to perform these highly responsible tasks. On the other hand, the nuclear competence and knowhow, as well as the promotion of young talents in the relevant scientific fields must be preserved. Technological and economic solutions are in demand for the various plants due to the different specifics of nuclear power plants. This will still require e.g. in the field of radiation protection highly qualified and well trained staff in future. The training of these skilled employees will require expanding the subject matter taught at universities, colleges and polytechnics to suit the changed parameters. The chair for hydrogen and nuclear energy technology at the TU Dresden will in future offer lectures as part of a new teaching discipline with the focus on dismantling and disposal. The course 'Dismantling nuclear power plants' took place for the first time in the summer semester 2013. It is organised as a three-day block seminar with an excursion to the company NIS Ingenieurgesellschaft mbH in Alzenau. The company NIS is a subsidiary of the Siempelkamp Nukleartechnik GmbH. This article intends to provide an overview of the contents of the courses and the impressions of the participants. In this way the TU Dresden is making a further contribution to preserving nuclear competence and inter-disciplinary dialogue. (orig.)

    The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil. The Hydrology Department of Brandenburgische Technische Universitaet Cottbus, on behalf of the Thuringian Environmental Authority, investigated the state of the art of discharge of precipitated water into natural soils. The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection.

    1987-01-01

    Numerical methods are developed for control of three dimensional adaptive test sections. The physical properties of the design problem occurring in the external field computation are analyzed, and a design procedure suited for solution of the problem is worked out. To do this, the desired wall shape is determined by stepwise modification of an initial contour. The necessary changes in geometry are determined with the aid of a panel procedure, or, with incident flow near the sonic range, with a transonic small perturbation (TSP) procedure. The designed wall shape, together with the wall deflections set during the tunnel run, are the input to a newly derived one-step formula which immediately yields the adapted wall contour. This is particularly important since the classical iterative adaptation scheme is shown to converge poorly for 3D flows. Experimental results obtained in the adaptive test section with eight flexible walls are presented to demonstrate the potential of the procedure. Finally, a method is described to minimize wall interference in 3D flows by adapting only the top and bottom wind tunnel walls.

    Anyone creating sources of danger in a public place must take proper precautions to prevent a hazard from actually arising. Work such as the construction or renovation of generating plants, pipe networks or district heat substations, the operation of heating installations and plants and the use of heating water and steam as media for the supply or district heating are potential sources of danger which may lead to accidents. The utility is liable for material damage and bodily harm. The only possible way of precluding liability is to prove that it has taken all possible measures for precluding risk at the outset within the organization itself, to the greatest possible extent. Not only must administration and line management be properly structured for this purpose, but administrative efficiency must also be demonstrated by a working system of delegation of tasks and responsibilities and the optimum organisation of processes and interfaces.

    In Germany bioenergy production and consumption are promoted and encouraged by means of the Renewable Energy Law, which has as its objectives transforming the energy system and preventing climate change. In recent years several forms of bioenergy have been criticized as leading to ecological and socioeconomic risks. This study presents life cycle assessments (LCA) for existing bioenergy processes. The LCAs were conducted as a part of the Project ''Renewable Energy Regions: Socio-Ecology of Self-Sufficiency''; the objective was to assess the ecological impact of the selected bioenergy processes in order to calculate the overall ecological impact of existing bioenergy plants. The results prove that the usage of agricultural biomass such as corn and wheat for biogas production leads to negative ecological impacts such as eutrophication and acidification. If greenhouse gas emissions from land-use change are included, the net effect in comparison to the usage of fossil energies will only be small or even negative; however, when residues such as manure or materials from landscape management are used as substrates for biogas production they lead to several positive ecological impacts. Residual forest wood or wood from short-rotation coppices used in co-generation show the highest greenhouse gas reduction potential among the investigated processes. It must, however, be assumed that the potential of residual forest wood in Germany is already largely being tapped. Regions that have made bioenergy a priority thus should limit the usage of agricultural biomass for energy production to specific crops such as short-rotation coppices and floral and herbaceous perennials. Additionally, future challenges will require strategies to improve cascade utilization and gathering and efficient usage of residues.

    This project started on 1 January 1996 with DM 3.7 million funds from the BMFT. Originally scheduled for three years, it was extended by a further 11 months for various reasons. Its intention was to reduce the cost of future solar thermal power plants. Particular emphasis was given to the parabolic trough technology asit is closest to commercialisation. Three strategies were involved: 1. Further development and qualification of components for the parabolic trough collector (WG PAREX); 2. Development of instruments for measuring radiation flux distribution in parabolic trough collectors (WG PARMESAN); 3. Development, verification and application of software tools for analysing the complex dynamic response of solar thermal power plants (WG SISTA). [German] Das hier dargestellte Projekt begann am 1.1.1996 und wurde vom Bundesministerium fuer Forschung und Technologie (BMFT) mit etwa 3,7 Mio. DM gefoerdert. Es hatte eine geplante Laufzeit von drei Jahren, wurde aber aufgrund von unterschiedlichen Verzoegerungen (Mitarbeiterwechsel, Defekte an Versuchsanlagen) kostenneutral um 11 Monate verlaengert. Gesamtziel des Projekts war es, zur Kostensenkung bei zukuenftigen solarthermischen Kraftwerken beizutragen. Dabei stand insbesondere die Parabolrinnentechnik im Vordergrund, da sie im Vergleich zu anderen solarthermischen Technologien einer weiteren kommerziellen Vermarktung derzeit am naechsten steht. Es wurden drei Schwerpunkte verfolgt: 1. Die Weiterentwicklung und Qualifizierung von Komponenten fuer den Parabolrinnenkollektor (Arbeitspaket 'Parabolrinnenexperimente', kurz PAREX) 2. Die Entwicklung von Messtechnik zur Bestimmung von Strahlungsflussverteilung bei Parabolrinnenkollektoren (AP 'Parabolrinnen-Messanlage', kurz PARMESAN) 3. Die Erstellung, Verifikation und Anwendung von Softwarewerkzeugen zur Analyse des komplexen dynamischen Verhaltens von solarthermischen Kraftwerken (AP 'Simulation solarthermischer Anlagen', kurz SISTA) (orig.)

    The transformation of the energy system to a de-carbonized energy supply requires a coordinated interaction between the sectors electricity, heat and transport. Thereby, the coupling of the electricity sector with the heating sector is one of the key measures in the transformation. The inclusion of wind and solar energy in the grid can be optimized by exact feed in forecasts, the coupling to the heat sector by means of heat pumps and power-to-heat (heater) allows more flexibilisation of the demand side. This interaction is made possible by intelligent solutions of systems engineering and power management. The development of appropriate incentives, market mechanisms and business models is also required, to make this coupling also economic successful. The contribution present die 80% scenario for the year 2050 created in the research project ''Interaction RES electricity, heat and transport'' and gives examples of future requirements and developments on this topic. [German] Die Transformation des Energieversorgungssystems zu einer de-karbonisierten Energiebereitstellung bedingt ein koordiniertes Zusammenspiel der Sektoren Strom, Waerme und Verkehr. Dabei ist die Kopplung des Stromsektors mit dem Waermesektor eine der entscheidenden Massnahmen bei der Transformation. Die Aufnahme von Wind- und Sonnenenergie in das Netz kann durch genaue Einspeiseprognosen optimiert werden, die Kopplung zum Waermesektor mittels Waermepumpen und Power-to-Heat (Heizstab) ermoeglicht die weitere Flexibilisierung der Nachfrageseite. Diese Interaktion wird durch intelligente Loesungen der Systemtechnik fuer das Energie- und Netzmanagement ermoeglicht. Die Entwicklung von entsprechenden Anreizsystemen, Marktmechanismen und Geschaeftsmodellen ist ebenfalls erforderlich, um diese Kopplung auch wirtschaftlich erfolgreich zu gestalten. Der Beitrag stellt das im Forschungsvorhaben ''Interaktion EE-Strom, Waerme und Verkehr'' erstellte 80 %-Szenario fuer das Jahr 2050 vor und zeigt anhand von Beispielen zukuenftige Anforderungen und Entwicklungen zu dieser Thematik auf.

    The new German regulation on energy conservation in buildings (draft) offers certain flexibility for choosing the quality of the building envelope (thermal resistance and air tightness) and of the HV equipment (AC not considered) in order to balance and minimize the yearly heating-energy demand. Up to now, there was little consideration given to control systems which are able to assist the inhabitants in using heating and ventilation efficiently. The performance of such systems is being discussed. (orig.)

    To begin with, an outline is given of the physical fundamentals, the data processing procedure, and the structure of the various scanning systems. The authors give only general information on these as detailed descriptions are offered by the producers. Practical hints are given on positioning of patients and on data documentation which have been tried with good results at the authors' institutions. As regards the description of normal anatomical structures, only one planigraphic angle is described as there are atlases presenting all possible planigraphic planes and angles. However, the changes in shape of anatomical structures are described for different angles. The chapter on interpretation is based on the information to be recognized on the pictures. Considerations for differential diagnoses are listed for every single parameter. A diagnosis of probability ought to be possible merely on the basis of the data, without any clincial information. Anamnesis and clinical findings are required to increase diagnostic reliability. In the last chapter, the CT pictures of intraeranial, neurological diseases are presented. Besides typical pictures, also non-typical and infrequent findings are given.

    This article discusses the psychological aspects and the technical tactfulness needed when implementing daylight-controlled lighting systems. On the basis of experience gained, the author concludes that the same amount of energy can be saved if the lighting is controlled half-automatically or when the lighting is always switched off when rooms are unoccupied. The article reviews the experience gained with automatically-dimmed lighting in a school in Zurich, Switzerland, and at the University of Zurich. The requirements placed on the control of lighting by the 'Minergie' low energy consumption standard are discussed. Control methods that have been implemented in various public buildings are looked at and the variations in the personal sensitivity of users to varying lighting levels are discussed. The placing of sensors for light-level and occupancy is discussed.

    Experimental and theoretical investigations were made in order to define the main influencing parameters of gap flow and secondary flow in compressor cascades. The investigations and results are presented in detail. [German] Im Rahmen des FVV-Forschungsvorhabens 'Randstroemung in Verdichtergittern' wurden am Institut fuer Strahlantriebe der Universitaet der Bundeswehr Muenchen umfangreiche experimentelle und theoretische Untersuchungen zur Bestimmung der wesentlichen Einflussgroessen auf die Spalt- und Sekundaerstroemung in Verdichtergittern durchgefuehrt. Als Parameter wurden die Spaltweite, das Schaufelseitenverhaeltnis mit Schaufelhoehe und Sehnenlaenge, die aerodynamische Belastung und die Zustroemgrenzschichtdicke variiert. Zur Analyse der Stroemungsvorgaenge wurden Fuenflochsonden-Stroemungsfeldtraversierungen, Profil- und Seitenwanddruckverteilungsmessungen und Laser-Zwei-Fokus-Messungen im Spalt herangezogen. Die experimentellen Untersuchungen zeigen eine komplexe Wechselwirkung zwischen Spalt- und Kanalwirbel. Die Spalt- und Sekundaerverluste steigen mit der Spaltweite und der aerodynamischen Belastung, wobei der Anstieg eine welchselseitige Abhaengigkeit der Parameter aufweist. Gegenueber dem Schaufelseitenverhaeltnis verhalten sich die Spalt- und Sekundaerverluste umgekehrt proportional. Die Zustroemgrenzschicht beeinflusst zwar den Verlust- und Abstroemwinkelverlauf ueber der Schaufelhoehe, jedoch nicht die sich abzueglich des Profil- und Zustroemverlustes ergebenden Spalt- und Sekundaerverluste. Die verwendeten 3D Stroemungsberechnungsverfahren erfassen die Stroemungsphaenomene qualitativ gut, wobei der Spaltmodellierung eine besondere Rolle zukommt. Die realistische Spaltmodellierung erlaubt einen sehr detaillierten Einblick in das Stroemungsgeschehen im Spalt. Die Verlustberechnung erweist sich jedoch als sehr unsicher. Auf der Grundlage einer umfangreichen Literaturanalyse wurden die verfuegbaren Korrelationen zur Berechnung des Spaltverlustes und

    Attempting to counteract the consequences of climate change, leading industrial nations have agreed on reducing their CO 2 emissions significantly. To reach these reduction goals, it is essential to reduce the CO 2 emissions in the field of energy conversion. This PHD thesis covers the field of chemical looping combustion, a technology that uses fossil fuels for energy conversion with inherent capture of CO 2 . Since the research regarding chemical looping had so far focused mainly on lab scale or small scale experiments, a 1 MW pilot plant has been erected at Technische Universitaet Darmstadt in order to investigate the process in a semi-industrial scale and to check the process efficiency with commercially usable equipment. This pilot consists of two interconnected fluidized bed reactors and has an overall height of more than 11 m. In this thesis, some experiments with ilmenite - used as the oxygen carrier - are explained. Furthermore, the design, erection and commissioning of the pilot plant are presented as well as the results of the first test campaigns. The evaluation of the latter proves that the process can be handled in the design configuration and that CO 2 can be safely captured in a pilot plant of this scale.

  17. Lift force fluctuations of magnetically levitated vehicles with an integrated synchronous linear motor and their significance for the technical security

    Mnich, P; Huebner, K D

    1980-07-15

    In this paper the influence of the motor current on the magnetic force is investigated by an analytical method. With the integrated synchronous linear motor the reactions of the current sheet on the excitation field are depending on the pole angle and the amplitude of the current sheet. For an undisturbed operation - current sheet and induction wave in phase - the influence of the motor current on the magnetic force can be neglected. In case of a disturbed performance, i.e. when the pole angle is changing periodically, fluctuations of the magnetic force will be found. This effect has to be compensated by a reserve magnetic force in the levitation control. With the technical data for the new magnetic levitation pilots plants (International Traffic Fair 1979 at Hamburg and Transrapid - Pilot Plant Emsland) the stated relations are evaluated. Approximated relations for the levitation force are derived. For comparison, a finite-difference computer programme from the 'Institut fuer elektrische Maschinen, Antriebe und Bahnen, Technische Universitaet Braunschweig' is applied. The approximated relations developed in this paper are verified - with a sufficient precision - by the numerical calculations.

    Numerous mine workings in rock salt are used in the present for the disposal of low and intermediate level radioactive waste or chemo-toxic waste. In order to get information about the integrity of the mine workings' barrier or to calculate geotechnical sealing structures, numerical tools are necessary. For this purpose, the constitutive model TUBSsalt was developed at the Institute for Soil Mechanics and Foundation Engineering of the Technische Universitaet Braunschweig. The constitutive model's formulation enables the simulation of the significant creeping mechanisms as well as damage, failure and healing. The influence of the temperature on the mechanical behavior is also considered. The parameters can be determined by laboratory tests. The implementation of the constitutive model is realized in two different numerical program systems. By using a uniform set of parameters for a type of salt a good match between the calculated data and the measured data can be achieved. In order to get a versatile and reliable tool for the calculation of cavities in rock salt, the validation of the constitutive model will be continued with more complex structures.

  19. Modification of a compressor performance test bench for liquid slugging observation in refrigeration compressors

    Compressor performance test procedures are defined by the standard DIN EN 13771, wherein a variety of possible calorimeter and flow rate measurement methods are suggested. One option is the selection of two independent measurement methods. The accuracies of both selected measurement methods are essential. The second option requires only one method. However the measurement accuracy of the used device has to be verified and recalibrated on a regular basis. The compressor performance test facility at the Technische Universitaet Dresden uses a calibrated flow measurement sensor, a hot gas bypass and a mixed flow heat exchanger. The test bench can easily be modified for tests of various compressor types at different operating ranges and with various refrigerants. In addition, the modified test setup enables the investigation of long term liquid slug and its effects on the compressor. The modification comprises observational components, adjustments of the control system, safety measures and a customized oil recirculation system for compressors which do not contain an integrated oil sump or oil level regulation system. This paper describes the setup of the test bench, its functional principle, the key modifications, first test results and an evaluation of the energy balance.

    Purpose: Although the carcinogenic effect of ionizing radiation is well known, knowledge gaps persist on the health effects of low-dose radiation, especially in children. The cancer incidence rate in a cohort of 92,957 children diagnosed using X-rays in the years 1976-2003 in the radiology department of a large university clinic was studied. Materials and Methods: Individual radiation doses per examination were reconstructed using an algorithm taking into account the dose area product and other exposure parameters together with conversion factors computed specifically for the equipment and protocols used in the radiology department. Incident cancer cases in the period 1980-2006 were identified via record linkage to the German Childhood Cancer Registry using pseudonymized data. Results: A total of 87 cancers occurred in the cohort between 1980 and 2006: 33 leukemia, 13 lymphoma, 10 brain tumors, and 31 other tumors. The standardized incidence ratio (SIR) for all cancers was 0.99 (95 % CI: 0.79 1.22). A dose-response relationship was not observed for all cancers, leukemia and lymphoma or solid tumors. The cancer risks for boys and girls did not differ. Conclusion: No increase in the cancer incidence risk in relation to very low doses of diagnostic ionizing radiation was observed in this study. However, the results are compatible with a broad range of risk estimates. (orig.)

    Results of a retrospective study at the University of Wuerzburg: Patients and methods: In a retrospective study the factors of influence on the locoregional control, the overall survival and the disease free survival of 106 patients with histological approved oropharyngeal cancer were tested with uni- and multivariate analysis. The median age at the date of the primary diagnosis was 55 years. A median follow up surveillance of 36 months could be achieved (between 5 to 126 months). In 18 cases (17%) the primary tumor could be removed in sano (safety margin >3mm). In 34 cases (32%) were detected close resection margins (<3mm) and in 54 cases the resection margins were not free of tumor cells (R1 resection). Patients, who were treated with chemotherapy, because of the increased recurrency risk, were 24% of the patient database. The concept of medical treatment: The tumorbed of the primary tumor and the cervical lymphatic drain received a radiation dose of 56 Gy (2 Gy/ treatment, 5 fractions a week). Patients with R0 resections received doses from 56 to 60 Gy. Patients with close resections margins received a higher dose of 60 to 66 Gy at the tumorbed and patients with R1 resections were treated with a boost up to 66 to 70 Gy. Patients with UICC 4 status with an increased recurrency risk received an additional chemotherapy with cisplatin (40mg/m{sup 2} a week) in 1 to 4 cycles as well a boost of the tumorbed up to 66 to 70 Gy. In the univariate analysis with the Kaplan-Maier Plat method following factors of influence were detected: tumor status (p-value 0,003), lymph node status (p-value 0,048), chemotherapy (p-value 0,047), second tumor (p-value 0,003) and the overall tumor volume (p-value 0,000). Results of the multivariate analysis In the Cox regression analysis the tumor status and the development of a second tumor were detected as factors of influence of the 5 year overall survival rate and the 5 year disease free survival survival rate. Regarding to the overall survival rate for the tumor status was detected a statistical significance of 0,015 and regarding the disease free survival was detected a significance of 0,025. The factor of influence of the second tumor had a significance for the overall survival of 0,015 and a significance regarding the disease free survival of 0,025. Conclusion: With the concept of medical treatment there could be achieved an improvement of the 5 year overall survival and the 5 year disease free survival. Patients with close resection margins had throughout better results as patients with a R0 resection. The consequence of those results should be an adjustment of the present concept of medical treatment of the R0 patients to the concept of patients with close resection margins. Patients who received a simultaneous radiochemotherapy, because of the increased risk of recurrence, the present concept of medical treatment effected an adjustment of the 5 year overall survival rate to patients without an increased risk of recurrence. There was no statistical significance in the multivariate analysis at the overall survival as well as at the disease free survival (overall survival p-value 0,064, disease free survival p-value 0,085).

    Summing up the contents of papers and discussions of the January 1993 meeting in Bochum, which gathered about 130 experts from politics, industry, science, the mining industry, the judiciasy, and the ministerial level of public administration, it can be stated that there is general approval among the experts of the new line of orientation given by the recent court rulings, towards a reassessment of the relationship between the mining industry and surface land ownership, strengthening the protection of third parties. This new approach having been readily adopted in practice, there already are many contracts reflecting the change in the mining industry's conception of itself, and experts wellcomed the turn away from the principle of 'tolerate and liquidate'.

    So far, there is little experience on the consequences of a relaxation of supply territory protection. Most of the plans are still in the experimenting stage, e.g. in Great Britain, the Netherlands, and West Germany. The USA have a certain tradition of deregulation, but do little to enforce things, while France is secure in its state monopoly energy supply. (orig./HP).

    It is advisable to analyse different alternatives of the generation and supply of electrical energy and thermoelectricity with renewable forms of energy, because the demand of fuels (e.g. coal and oil) and the energy costs rise continuously. Technical optimization and cost-effectiveness of the different alternatives are the most important points of tests. This was the reason why at the Department of Mechanical and Energy Engineering of the Leipzig University of Applied Science a test ground ''renewable forms of energy'' has been built up step by step for thirteen years including two photovoltaic systems with different tracking systems, two wind-mills, an air-water-heat-pump and a dish-stirling-system.

    Operation management is not restricted to the execution of operational measures. In order to be able to work together efficiently the different organisational units of a plant are dependent on the support of an intelligent operation management system. Such an operation management system must give the user`s working style priority over the system`s integration in the superordinate system. This is the only way to win the user`s acceptance and achieve the intended results now and over the long term. The most important thing to consider when planning the introduction of an operation management system are the likely processing costs. The one-time cost of procuring the necessary software is practically negligible. [Deutsch] Betriebsfuehrung ist keine ausschliesslich auf die Abwicklung der betrieblichen Massnahmen ausgerichtete Aufgabe. Die Organisationseinheiten des Betriebes muessen zur rationellen Bearbeitung durch ein intelligentes Betriebsfuehrungssystem unterstuetzt werden.

Nur so kann die Akzeptanz der Anwender erzielt sowie das geforderte Ergebnis erreicht und langfristig gesichert werden. Bei der Einfuehrung eines Betriebsfuehrungssystems sind insbesondere die langfristig zu erwartenden Bearbeitungskosten zu bewerten. Die einmaligen Anschaffungskosten der Software sind in Relation zu den Gesamtkosten praktisch ohne Bedeutung. (orig./RHM)

    The development of the power generation in Europe substantially is characterized by the process of liberalisation and the endeavours to climate protection. The ensuring of future supply security increasingly becomes more important. In order to achieve the climatic protection goal a multiplicity of technical options in the competitively organized market is available. In order to be competitive in such a market, certain requirements have to be expected to future power plants with CCS technology (CCS = carbon Capture and storage). By means of a European energy system model the question is to answered in the contribution under consideration which requirements to the CS technology have to be expected to the CCS technology.

    Patients with severe, life-threatening trauma require a fast and accurate clinical and imaging diagnostic workup during the first phase of trauma management. Early whole-body computed tomography has clearly been proven to be the current standard of care of these patients. A similar imaging quality can be achieved in the multiple trauma setting compared with routine imaging especially using rapid, latest generation computed tomography (CT) scanners. This article encompasses a detailed view on the use of CT in patients with life-threatening trauma. A special focus is placed on radiological procedures in trauma units and on the methods for CT workup in routine cases and in challenging situations. Another focus discusses the potential of dose reduction of CT scans in multiple trauma as well as the examination of children with severe trauma. Various studies have demonstrated that early whole-body CT positively correlates with low morbidity and mortality and is clearly superior to the use of other imaging modalities. Optimal trauma unit management means a close cooperation between trauma surgeons, anesthesiologists and radiologists, whereby the radiologist is responsible for a rapid and accurate radiological workup and the rapid communication of imaging findings. However, even in the trauma setting, aspects of patient radiation doses should be kept in mind. (orig.) [German] Polytraumatisierte Patienten beduerfen im Rahmen der initialen Schockraumversorgung einer schnellen und exakten klinischen und bildgebenden Diagnostik. Fuer ein optimales Schockraummanagement ist heute die essenzielle Bedeutung einer zeitnah durchgefuehrten Ganzkoerper-CT unbestritten. Insbesondere durch schnelle CT-Scanner der letzten Generationen kann im Rahmen der Schockraum-CT eine aehnlich gute Bildqualitaet wie in der Routinediagnostik erzielt werden. Dieser Artikel beleuchtet den Einsatz der CT im Schockraum bei polytraumatisierten Patienten, wobei das Hauptaugenmerk auf Methoden des radiologischen Managements sowie auf den verschiedenen Moeglichkeiten der Untersuchungsdurchfuehrung im Routineeinsatz und in Spezialsituationen liegt. Ein weiterer Schwerpunkt sind Moeglichkeiten und Strategien zur Dosisreduktion der Schockraum-CT sowie der Untersuchung polytraumatisierter Kinder. Zahlreiche Studien haben gezeigt, dass eine fruehe Ganzkoerper-CT-Untersuchung positiv mit einer niedrigen Mortalitaet und Morbiditaet korreliert und anderen Bildgebungsverfahren deutlich ueberlegen ist. Die optimale Schockraumversorgung erfordert eine interdisziplinaere Zusammenarbeit von Unfallchirurgen, Anaesthesisten und Radiologen, wobei die Radiologie fuer einen raschen und adaequaten Einsatz der bildgebenden Verfahren und die zeitnahe Kommunikation relevanter Befunde verantwortlich ist. Daneben sollte auch im Rahmen der Schockraum-CT die Patientenstrahlendosis im Hauptaugenmerk des Radiologen stehen. (orig.)

    The geological conditions in Germany allow maximum temperatures between 160 to 170 C free well head taking techno-economic constraint into consideration. This makes an electricity production for purely technical reasons possible, but only with low efficiencies due to physical constraints. That's why it assault big amounts of waste heat. For example, the existing geothermal power plants in Germany provide in average 18% of electricity and 82% of heat. This heat is use so far only to a very small degree. Even is a district heating system is operated to supply private households, this heat is used with less than 2.500 h per year. That's why the still hot thermal water is press back into the underground without any further utilization. For these reasons to achieve a technical and economic optimization it should be the aim to find different reasonable options to use this waste heat. One possibility is the coupling with a drying process at the location of the geothermal plant. Such options will be analyzed from a technical and economic point of view and some conclusions will be drawn. (orig.)

    Facades are not only a shell of the protected habitats and a boundary between the indoor climate and the environment of buildings. Facades also convert from previously passive elements to active building systems which perform various functions of the room conditioning (heating, cooling, ventilation, lighting, and so on). The associated increased demands on the system integration into facades require new solutions for the planning, implementation and operation of these innovative systems. Within the intelligent handling of increasing complexity, superior automation strategies have to be developed by means of facade automation. These automation strategies have to match the individual functions with each other, and to ensure a building sector comprehensive functionality. Furthermore, another criterion for the design of integrated facade systems is the consideration of the user's feeling with respect to comfort as well as the user's control and user's acceptance. In line with the research project AUTiFAS (= Automation of innovative facade systems), different automation strategies of the facades and room automation are considered on the basis of metrological investigations and simulation analyses. For this purpose, an innovative facade element with a decentralized ventilation unit and an integrated sunshade had to be integrated into a test room initially. The functionality and the constructional tightness of the total test stand had to be verified and matched to the requirements of the tests. With the objective to develop a standardized description of the control and regulation functions of the building sector comprehensive automation strategies, an automation library was developed based on standard structures and forms of representation using a test facade as an example. The standards DIN EN 15232, IEC 61131 as well as the guidelines VDI 3813 and VDI 3814 provide the fundamentals. The developed automation strategies form the basis for the development of new control strategies of high quality. Two approaches of highly qualitative control methods were examined in this research project. The picking up of comfort criteria in the optimized control enables the consideration of user's needs. Another approach is the predictive control which is based on characteristic line models and aims a more energy-efficient operation.

    A possibility to supply energy from gaseous biomass is the generation of biogas and bio-SNG, respectively, with a subsequent conditioning to bio methane which can be fed in into the natural gas distribution system. Under this aspect, the author of the book under consideration reports on how the conventionally used natural gas can be substituted by the biogas. It is investigated whether the transformation of biogas or bio-SNG to bio methane is worthwhile under economic and ecologic aspects. It is also investigated to what extend natural gas can be exchanged by bio methane under consideration of the technical and legal frameworks.

    Many flows relevant for climate research, weather forecasting, heating, ventilation, air-conditioning (HVAC), and fire safety are characterized by relatively small velocities compared to the speed of sound. The efficient computation of such low Mach number flows requires computational methods that avoid the Courant-Friedrich-Lewy time step restriction, based on the speed of sound. An essential issue in the context meterological flow modelling, as investigated at the Potsdam Institute for Climate Impact Research, is the construction of efficient numerical schemes for such flows that are in conservation form with respect to all physically conserved quantities, i.e., mass, momentum, and energy. Extending initial developments by Klein et. al [9, 13, 15, 19, 20], a new scheme for such flows is currently under development which accounts for flows in three space dimensions, is fully conservative, with second order accuracy and covers the entire regime 0 {<=} M {<=} 1. To transfer this scheme to practical applications, the author has created the programm code MOLOCH. This technical report collects the background theory of the scheme and describes the current state of its implementation. The code is based on a finite-volume method using a cartesian grid. Currently, the scheme is limited to Zero-Mach number. The first four chapters describe the mathematical background of the scheme. After a short presentation of the underlying set of equations, the result of a one-scale asymptotic analysis is discussed to elucidate the main problems in the context of constructing numerical simulation schemes, and to motivate the construction of the method. Chapter 5 describes the details of the numerical technique and provides additional information regarding the discretization and the implementation of boundary conditions. Chapter 6 describes the implementation of gravitational forces, necessary to run the falling droplet test case, which will be described in Chapter 7. An empirical convergence study confirms the predicted second order accuracy of the implemented scheme. Current work in progress aims at extending the scheme presented here to the meteorologically important class anelastic, instead of incompressible, flow models. The computational code structure as presented here will transfer to these applications without change. (orig.)

    The German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P and T) could be considered as a technological option in the process of management of highly radioactive waste management, therefore a wide study has been conducted. In this group objectives for P and T and the boundary conditions of the phase out have been discussed. The fulfillment of the given objectives is analyzed using simulations of molten salt reactors with fast neutron spectrum. It is shown that the efficient transmutation of all existing transuranium isotopes would be possible in 3 to 4 reactors in a time frame of 45 to 60 years. Further on a detailed balance of different isotopic inventories is given to allow a deeper understanding of the processes during transmutation.

  11. Techno-economic optimization of flexible biogas concepts in the context of EEG; Technisch-oekonomische Optimierung von flexiblen Biogaskonzepten im Kontext des EEG

    Due to the introduction of direct marketing and flexibility premium of renewable energy by the Renewable Energy Act 2012 (EEG 2012), incentives were created to favour a more demand-oriented power supply from biogas plants (BGA). The decision for such an operational mode depends on on-site conversion units on the economic outcome of the plants throughout the whole operating time. To install new plants or transfer existing plants into a flexible mode of operation, investments in additional and more efficient combined heat and power plants (CHP), in additional gas and/or heat storage and other technical components are necessary. The analyses show that the flexibility premium, as an extra of the market premium model, creates the greatest incentive for a more flexible generation of electricity from biogas. In addition, an intelligent management optimization can generate additional revenues on EPEX SPOT SE and balancing energy market. The additional revenues of more demand-oriented power supply from biogas plants are highly dependent on plant-specific conditions. From an economic perspective, a duplication of the installed electrical capacity seems to be the most beneficial option for a transition to a demand-driven operation mode of an average biogas model plant under the current legal framework (EEG 2012).

    This report documents the status of the research and development goals reached within the reactor safety research project RS1503 ''Development and Application of Neutron Transport Methods and Uncertainty Analyses for Reactor Core Calculations'' as of the 1{sup st} quarter of 2013. The superordinate goal of the project is the development, validation, and application of neutron transport methods and uncertainty analyses for reactor core calculations. These calculation methods will mainly be applied to problems related to the core behaviour of light water reactors and innovative reactor concepts. The contributions of this project towards achieving this goal are the further development, validation, and application of deterministic and stochastic calculation programmes and of methods for uncertainty and sensitivity analyses, as well as the assessment of artificial neutral networks, for providing a complete nuclear calculation chain. This comprises processing nuclear basis data, creating multi-group data for diffusion and transport codes, obtaining reference solutions for stationary states with Monte Carlo codes, performing coupled 3D full core analyses in diffusion approximation and with other deterministic and also Monte Carlo transport codes, and implementing uncertainty and sensitivity analyses with the aim of propagating uncertainties through the whole calculation chain from fuel assembly, spectral and depletion calculations to coupled transient analyses. This calculation chain shall be applicable to light water reactors and also to innovative reactor concepts, and therefore has to be extensively validated with the help of benchmarks and critical experiments.

    Often, legal regulations governing the electricity and gas industries are thought prematurely to apply to district heating as well. The author shows that the technical and economic boundary conditions of district heating are quite different in many respects. He starts by explaining the concept of district heating and analyzing its economic boundary conditions. The next instalment will follow in the next issue of EuroHeat and Power and will focus on the heat market and its legal boundary conditions.

    Purpose: Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) are the standard methods of ensuring long-term enteral food intake in patients with dysphagia caused by neoplasia or neurological disorders. High-grade obstructions of the upper digestive tract or inadequate transillumination can prevent PEG. CT-guided percutaneous gastrostomy (PG) represents a special technique for enabling gastrostomy in patients for whom the endoscopic method is impossible. The aim of this study was to evaluate the results and complications of CT-guided percutaneous gastrostomy. Materials and Methods: CT-guided PG was performed in 83 patients, mostly with malignancy of the upper respiratory or digestive tract. Medical records for these patients were reviewed, and the results and complications of the CT-guided PG were analyzed retrospectively. Complications were grouped into four categories: Major and minor complications as well as early and late complications. Results: In 95.2 % of all cases (79/83), CT-guided PG was successful in the first attempt. Within the first 3 days, 5 major complications including 4 tube dislocations and one case of peritonitis were found in 4/79 patients (5.1 %). One of these patients experienced two early major complications. Early minor complications, mainly local skin irritations and temporary stomachache, were observed in 31 patients (39.2 %). Three days after CT-guided PG, 4 cases of major complications were documented, yielding a total rate of major complications was 8.7 % (7/79). Hemorrhage requiring blood transfusion or perforation after gastrostomy was not observed. 29.1 % of the patients (23/79) experienced late minor complications. (orig.)

    The statement is not new, but is repeatedly a tropical subject. Further technological developments permit advances, e.g. in medicine, production, communication or energy supply. This is particularly clear from the example of natural gas. As with other fossil energy sources the resources are also limited in this case, which is all the more painful, because natural gas is an ideal product in the creation of the energy revolution. In this situation it is highly appropriate that with a special method it is possible to exploit deposits, which could not be developed economically until a few decades ago. (orig.)

    Historical analyses of what metabolism has been conceived of, how concepts of metabolism were related to disciplines such as nineteenth-century nutritional physiology or twentieth-century biochemistry, and how their genealogies relate to the current developments may be helpful to understand the various, at times polemic, ways in which the boundaries between metabolism and heredity have been re-drawn. Against this background, a small number of scholars gathered in Berlin for a workshop that equally aimed at bringing new stories to the fore, and at considering seemingly known ones in a new light. Some aspects of the discussions are summarized in this paper.

    This introduction into the finding and ordering of technical literature addresses both students and doctoral candidates as well as engineers which are already practising their profession. The first chapter - library science - gives a basic description of bibliographic research in an average scientific library: reading rooms and their function, structure of catalogues, structure of the reference library as well as lending and interlibrary lending methods. The technical information systems are described in detail. Finally, translation services and technical information and documentation centres are named. The second chapter - bibliographic research - lists the most important aids in finding technical references. Chapter three outlines the topical complex of scientific work. It provides information on how to organize written scientific publications in a formally correct way, how to quote and to list the references. Chapter four contains an index of terms from library and bibliographic science which is to help the beginner to understand the technical terms which cannot completely be excluded from this orientation aid.

  1. Model-based analysis of digital radio frequency control systems for a heavy-ion synchrotron

    International Nuclear Information System (INIS)

    Spies, Christopher

    2013-12-01

    In this thesis, we investigate the behavior of different radio frequency control systems in a heavy-ion synchrotron, which act on the electrical fields used to accelerate charged particles, along with the longitudinal dynamics of the particles in the beam. Due to the large physical dimensions of the system, the required precision can only be achieved by a distributed control system. Since the plant is highly nonlinear and the overall system is very complex, a purely analytical treatment is not possible without introducing unacceptable simplifications. Instead, we use numerical simulation to investigate the system behavior. This thesis arises from a cooperation between the Institute of Microelectronic Systems at Technische Universitaet Darmstadt and the GSI Helmholtz Center for Heavy-Ion Research. A new heavy-ion synchrotron, the SIS100, is currently being built at GSI; its completion is scheduled for 2016. The starting point for the present thesis was the question whether a control concept previously devised at GSI is feasible - not only in the ideal case, but in the presence of parameter deviations, noise, and other disturbances - and how it can be optimized. In this thesis, we present a system model of a heavy-ion synchrotron. This model comprises the beam dynamics, the relevant components of the accelerator, and the relevant controllers as well as the communication between those controllers. We discuss the simulation techniques as well as several simplifications we applied in order to be able to simulate the model in an acceptable amount of time and show that these simplifications are justified. Using the model, we conducted several case studies in order to demonstrate the practical feasibility of the control concept, analyze the system's sensitivity towards disturbances and explore opportunities for future extensions. We derive specific suggestions for improvements from our results. Finally, we demonstrate that the model represents the physical reality

    With support from the Federal Minister of Consumer Protection, Nutrition and Agriculture through the Fachagentur Nachwachsende Rohstoffe e.V. (Renewable Fuels Agency), a project group of Goettingen University was able to demonstrate how complete conversion to biomass of heat and power supply can be achieved for a whole village with maximum social acceptance, environmental compatibility, and economic and technical efficiency. This and further projects will provide flexible, generally applicable concepts for wider use and are expected to give new impetus to bioenergy and help reduce CO2 emissions. This documentation presents the results of the first project phase, which lasted from October 2000 through November 2002. After describing the criteria for which the model village was selected, the work carried out by the various scientific disciplines cooperating in the project (environmental geoscience, crop research, soil research, agricultural economy, psychology, sociology and political science) is described, and the current project status is outlined.

  3. Proposing an approach for the assessment of environmental impacts of offshore wind farms in Europe

    2011-07-01

    Full text: Analyses of numerous EIS and EIA in the chosen countries, which have been worked out by the authors, have documented that the assessments failed to standardize both the prognosis and the assessment method. The assessment and the relevance of the manifold provided data tends to remain vague and can only hardly been used by the authorizing bodies. Thus, decision makers need an appropriate, transparent and comparable decision-making 'portfolio' to provide at best bullet-proofed EIA documents, based on a systematic analysis of research results, baseline surveys and a prognosis of the expected impacts. A satisfactory state of research or good practice for the assessment of the environmental impacts, which also enables comparability and cumulative considerations of the impacts of offshore wind farms in an international context, should be reached. A transparent evaluation approach of data for the analysis of the relevant issues therefore was essential. Carrying this in mind the Technische Universitaet Berlin developed proposals for semi-quantitative assessment models for migratory birds, sea and resting birds and harbour porpoises that, if used within the EIA, could provide the permit requirements more transparent with relevant data and assessments to the necessary decision-making basics. Because of the differences of impact correlations between the diverse natural assets and the offshore wind farms, individual models have been developed for several impact correlations, which have been identified as especially significant for the real decision making process. The numerous influencing factors of each impact therefore have been compiled. With the elaborated models these factors are linked systematically. The obtained data can be used for a comparison with the social given objectives (in form of legal thresholds). Therefore the presented models have to be established inside the EIS as well as in the approval system. So it could bring advantages in the

  4. On a comprehensive evaluation of Moessbauer hyperfine spectra measured on different types of magnetic nanoparticles

    International Nuclear Information System (INIS)

    Kraken, Mathias

    2014-01-01

    Magnetic nanoparticles (MNPs) nowadays have a wide variety of applications that are mostly based on the fact that MNPs below a critical size consist of only a single magnetic domain. The big magnetic moments of these MNPs may fluctuate, driven by thermal excitations and controlled by magnetic anisotropies and interparticle interactions. Successful applications go along with a good control of the properties of the MNPs, which requires detailed knowledge about the preparation process and a proper characterization. These are the main topics this thesis deals with. First, the characterization of the MNPs using Moessbauer spectroscopy is discussed. Despite it is a standard method in research on iron-based MNPs, most publications only present a qualitative discussion of measurements, since available analysis models for dynamic hyperfine spectra are not capable of a satisfying description. Here, a modified version of an established model is presented, which proved to be applicable to the majority of hyperfine spectra and allows deriving detailed microscopic information about magnetic fluctuations on nanoscale. This model is succesfully used, to study the preparation of MNPs with the so-called non-aqueous sol-gel method (a cooperation with the Institut fuer Partikeltechnik, Technische Universitaet Braunschweig). In the last part of the thesis, a model is developed that describes the Moessbauer spectra of magnetically fluctuating iron clusters in different non-magnetic metallic matrices (silver and ytterbium). This part is based on a cooperation with the Centro Brasileiro de Pesquisas Fisicas, Rio de Janeiro, Brasil. The results of this thesis present possibilities for a detailed quantitative analysis of the magnetic dynamics derived from Moessbauer spectra measured on iron-based MNPs and nanoscale clusters.

    The BMW AG Munich, Drive system development, Test and simulation systems, and the University of Tuebingen, chair' of Computer Architecture at the Wilhelm-Schickard-Institute for Computer Science, worked together in the project MOTOP to solve a number of optimization tasks in the application of motor control units. The most important research topic was the development of the online optimization algorithm mbminimize with a robust constraint handling. The goal was to bring the new software developed in the project to the point where it is directly usable at the motor test bed. This goal was met until the end of the project in so far, as a robust modelling of the primary objective function, a robust parameter change strategy (including retraction strategy in case of a parameter limit violation), a variable limit modelling and an optimized parameter change strategy could be realized. Another important point was the development of active learning methods for these applications. These methods allow the integration of newly measured data directly into the online measurement point planning, reducing the total number of measurements considerably, and improving the quality of the models.

    A number of national and international societies published recommendations regarding the required equipment and manpower assumed to be necessary to treat a number of patients with radiotherapy. None of these recommendations were based on actual time measurements needed for specific radiotherapy procedures. The German Society of Radiation Oncology (DEGRO) was interested in substantiating these recommendations by prospective evaluations of all important core procedures of radiotherapy in the most frequent cancers treated by radiotherapy. The results of the examinations of radiotherapy with intensity-modulated radiation therapy (IMRT) in patients with different tumor entities are presented in this manuscript. Four radiation therapy centers [University Hospital of Marburg, University Hospital of Giessen, University Hospital of Berlin (Charite), Klinikum rechts der Isar der Technischen Universitaet Muenchen] participated in this prospective study. The workload of the different occupational groups and room occupancies for the core procedures of radiotherapy were prospectively documented during a 2-month period per center and subsequently statistically analyzed. The time needed per patient varied considerably between individual patients and between centers for all the evaluated procedures. The technical preparation (contouring of target volume and organs at risk, treatment planning, and approval of treatment plan) was the most time-consuming process taking 3 h 54 min on average. The time taken by the medical physicists for this procedure amounted to about 57 %. The training part of the preparation time was 87 % of the measured time for the senior physician and resident. The total workload for all involved personnel comprised 74.9 min of manpower for the first treatment, 39.7 min for a routine treatment with image guidance, and 22.8 min without image guidance. The mean room occupancy varied between 10.6 min (routine treatment without image guidance) and 23.7 min (first

    Problem. How are improvements in productivity in connection with RIS/PACS to be defined? What do they cost? To limit the problem to the relevant topics, we first describe the objectives of a radiology department and the identified bottlenecks in the workflow. How to define and assess the improvements is discussed.Methods. The case in question for this study is the RIS/PACS project at the ''Klinikum der Universitaet Muenchen, Campus Grosshadern''. The goals of the project and its present status are reviewed. The project is not yet completed, so this is a ''midterm'' report.Results and discussion. We describe the status of the achieved and not yet achieved goals and of the eliminated bottlenecks. On the plus side, for example, nearly 100% of all digitally generated images (except mammogramms) are digitally archived. They are accessible to the same percentage in radiology via PACS and in the hospital via the webbased intranet image distribution system when needed. In some radiology areas, such as multislice CT, already the reporting can no longer be performed without softcopy image interpretation. However, the full elimination of hardcopy images is still not reality, since the distribution to DICOM viewers for selected requesters with demands for almost reporting quality, high cost image displays is still in the testphase. To reduce film costs, images are being printed on a high resolution paper printer in addition to the intranet distribution during this transition period. On the negative side, due to a lack of job positions in the transcription rooms, about 40% of the reports are still being handwritten by radiologists. Furthermore, the dictated and transcribed reports are usually still not available early enough in the RIS and thereby in the intranet report distribution of the hospital. Here only a speech recognition system can remedy the situation. As soon as this problem is solved and the image distribution to the DICOM viewers works routinely, the reports and

    OnToPV is the project of an online tour guide through the PV-plant of the new Munich trade fair. The first focs was to provide an interactive circuit of a PV-plant. Within a virtual tour different areas of the plant should be made accessible over the internet. For this purpose a three-dimensional, multimedia guidance was developed for the PV-plant of the new Munich trade fair with informative diagrams, *.pdf-files and retrievable video-files. In such a way interested internet-users could experience with minimum system requirements, local- and time-independently the PV-plant in its structure and components and could receive different background informations in addition. From the view of the plant operators such an internet project serves on the one hand as an additional source of information where questions could be referred to and on the other hand as sort of advertisement for the technology and the PV-system. In addition the attractiveness of the internet appearance of the plant operator rises and the public awareness of such projects could increase. Seen from the user perspective - such an internet project gives private or business users the possibility to inform themselves interactively, purposefully and with the possibility to move through the plant on their own. Users could utilize the guidance through the plant without overcoming far geographical distances, saving time and money. Perhaps this source of information helps awaking a larger consciousness for renewable energies. The result OnToPV showed the various possibilities offered by projects of this kind in the internet. Ideas of possible extensions as for example the integration of current PV-plant operational data or of a virtual learning platform illustrate the perspectives of the project. Virtual guidance of this kind for various types of power plants are conceivable. (orig.)

    A questionnaire was mailed in 3 years (1994, 1995, 1996) to all radiation facilities in Germany, which assessed equipment, indications, number of patients and treatment concepts. A total of 134 (88%) institutions returned all requested data: 22 in East and 112 in West Germany; 30 in university and 104 in community/private hospitals. The average data of each institution and of all institutions were analyzed for frequencies and ratios between different regions and institutions. A mean of 2 (range 1 to 7) megavoltage (Linac/Cobalt 60) and 1.4 (range 0 to 4) orthovoltage units were available per institution; 32 (24%) institutions had no orthovoltage equipment. A mean of 20,082 patients were treated per year: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 nail bed infection, 23 parotitis, 134 not specified), 12,600 (63%) for degenerative diseases (2,711 peritendinitis humeroscapularis, 1,555 epicondylitis humeri, 1,382 heel spur, 2,434 degenerative osteoarthritis, 4,518 not specified), 927 (5%) for hypertrophic diseases (146 Dupuytren's contracture, 382 keloids, 155 Peyronie's disease, 244 not specified), 1,210 (6%) for functional disorders (853 Graves' orbitopathy, 357 not specified), and 4,889 (24%) for other disorders (e.g. 3,680 heterotopic ossification prophylaxis). In univariate analysis, there were significant geographical (West vs East Germany) differences in the use of radiotherapy for inflammatory and degenerative disorders and institutional differences (university vs community/private hospitals) in the use of radiotherapy for hypertrophic and functional disorders (p<0.05). The prescribed dose concepts were mostly in the low dose range (<10 Gy), but varied widely and inconsistently within geographic regions and institution types.

All three types of boron lipids contained the anionic dodecaborate cluster as the headgroup. Their effects on two different tumor models in mice following intravenous injection were tested; for this, liposomes with boron lipid, distearoyl phosphatidylcholine, and cholesterol as helper lipids, and containing a polyethylene glycol lipid for steric protection, were administered intravenously into tumor-bearing mice (C3H mice for SCCVII squamous cell carcinoma and BALB/c mice for CT26/WT colon carcinoma. With the exception of one lipid (B-THF-14, the lipids were well tolerated, and no other animal was lost due to systemic toxicity. The lipid which led to death was not found to be much more toxic in cell culture than the other boron lipids. All of the lipids that were well tolerated showed hemorrhage in both tumor models within a few hours after administration. The hemorrhage could be seen by in vivo magnetic resonance and histology, and was found to occur within a few hours. The degree of hemorrhage depended on the amount of boron administered and on the tumor model. The observed unwanted effect of the lipids

    A neutronics experiment has been performed in the frame of European Fusion Technology Program on a mock-up of the EU Test Blanket Module (TBM), Helium Cooled Pebble Bed (HCPB) concept, with the objective to validate the capability of nuclear data to predict nuclear responses, such as the tritium production rate (TPR), with qualified uncertainties. The experiment has been carried out at the FNG 14-MeV neutron source in collaboration between ENEA, Technische Universitaet Dresden, Forschungszentrum Karlsruhe, J. Stefan Institute Ljubljana and with the participation of JAEA. The mock-up, designed in such a way to replicate all relevant nuclear features of the TBM-HCPB, consisted of a steel box containing beryllium block and two intermediate steel cassettes, filled with of Li 2 CO 3 powder, replicating the breeder insert main characteristics: radial thickness, distance between ceramic layers, thickness of ceramic layers and of steel walls. In the experiment, the TPR has been measured using Li 2 CO 3 pellets at various depths at two symmetrical positions at each depth, one in the upper and one in the lower cassette. Twelve pellets were used at each position to determine the TPR profile through the cassette. Three independent measurements were performed by ENEA, TUD/VKTA and JAEA. The neutron flux in the beryllium layer was measured as well using activation foils. The measured tritium production in the TBM (E) was compared with the same quantity (C) calculated by the MCNP.4c using a very detailed model of the experimental set up, and using neutron cross sections from the European Fusion File (EFF ver.3.1) and from the Fusion Evaluated Nuclear Data Library (FENDL ver. 2.1, ITER reference neutron library). C/E ratios were obtained with a total uncertainty on the C/E comparison less than 9% (2 s). A sensitivity and uncertainty analysis has also been performed to evaluate the calculation uncertainty due to the uncertainty on neutron cross sections. The results of such

    The Institute for Nuclear and Particle Physics at the Technische Universitaet Dresden (TUD) has build a neutron physics laboratory at Forschungszentrum Dresden-Rossendorf (FZD) to investigate nuclear processes in materials. The experiments are focused on materials relevant to nuclear fusion. The laboratory is equipped with three intensive neutron sources. The first is a 14 MeV monochromatic neutron source based on the DT reaction (owned by TUD); the other two are continuous and pulsed white photoneutron sources based on (γ,xn) reactions. One pulsed photoneutron source is realized by FZD in cooperation with the TUD. The continuous photoneutron source utilises a tungsten radiator (Tungsten Photoneutron Source) to produce neutrons with a wide energy spectra. The TPNS uses the ELBE-accelerator as a source of electrons for neutron production. This process involves an intermediate step, where slowed down electrons produce bremsstrahlung (γ-rays) absorbed by tungsten nuclei. Consecutively, the excited nuclei emit neutrons. The neutron flux of the photoneutron source is five orders of magnitude higher than the flux of the DT neutron sources with appropriate moderation. The neutron spectrum of TPNS can be modified by moderators, in such a way that the spectrum is comparable to that in the first wall of a Tokamak-Reactor. That allows investigations with the typical neutron spectrum of the fusion reactor. The technical solution, initial operation and the first experiment are described in this work. The neutron source is, in particular, dedicated to quantitative investigations in fusion neutronics. A fusion reactor produces radioactive isotopes as a nuclear waste. The main activity is accumulated in the structural materials. Carefully selected structural materials can significantly minimize the activity and thereby the amount of nuclear waste. The purpose of this project is to find constructional materials with half-lives shorter than several years, which can be recycled

    The German Umweltbundesamt (federal environmental agency) commissioned a cost-benefit analysis to be made, testing the practical performance of fuel cell-driven automobiles, for state-of-the-art assessment of their benefits and drawbacks as compared to other available automotive fuel systems. Results available so far of calculations based on the cost-benefit analysis show that the targets involved, such as cutback of emissions and conservation of resources, can be realised within the foreseeable future at much lesser expense through the use of fuel consumption-optimized Otto engines offering lowest emission levels (of the type ULEV, ultra-low emission vehicle, or EURO 4 standard), as compared to the relevant contributions to emission reduction and other targets offered by the fuel cell-driven automobiles.(orig./CB) [Deutsch] Das Umweltbundesamt hat die Brennstoffzellentechnik im Verkehr einer Kosten-Nutzen-Betrachtung unterzogen, um zu ermitteln, welche Vor- und Nachteile sie im Vergleich zu anderen Antriebskonzepten im Verkehr nach derzeitigem Wissensstand hat.

    For the transition to a sustainable energy supply Germany anchored basic cornerstones in the EEG. In paragraph 2(2) of the EEG, the priority purchase, transmission and distribution of the electric energy by the network operator is controlled. From this for the Lechwerke AG results a completely new environment. The legal framework requires costly network expansion projects, especially in the network periphery in rural areas. For the distribution system operator the traditional grid extension is costly and time consuming. In search of alternative options, the use of ''network controller'' and ''950-V-lines'' is compared to the conventional grid extension. The measurements showed that the 20 kV grid upgrade is the ideal solution from a technical aspect. The improvement of the network situation is clearly evident in all measurements in accordance with DIN 50160. In turn, network expansion is the most expensive alternative and the costs often do not outweigh the benefits. Also the high costs for maintenance and operation have to be considered. Furthermore, often power reserves are created that may not be used. The 950-V line is a measure that improves the network situation. Considering the costs, this variant is the cheapest option, but only a maximum power of 30 kVA can be transmitted. The follow-up costs for maintenance and operation are significantly lower. The increase of the nominal voltage by the factor 2.3,8 in theory the short circuit power should increase by the factor (2.38){sup 2}. However this is not the case, since through the added impedance of the transformer the voltage increase in the cable pushes down the effect. The short circuit power is improved only by the factor 1.36. The power controller controls the voltage level (10-minute averages) quite well. However, flicker and voltage imbalance are increased. Harmonics are increased if they are caused by customers behind the power controller. The development of overvoltages due to the behavior of the controller under severe voltage dips have to be evaluated critically. If the electrical load is reduced or to the end of a power failure voltage values, which amount to well over 110% of the nominal voltage are caused by over-compensating of the controller. This can cause damage to equipment in customer installations and thus lead to demands for regress. In order to minimize these overvoltages at least for a fault in the MV and HV power grid, the response time of the network controller must be matched to the settings of the network protection devices. Thus, in these cases the occurrence of the overvoltages can be reduced, but cannot be avoided. Therefore, in practice the network controller can be used only in very limited cases, but in certain cases it is technically a good solution and can be implemented very quickly. Here, the current and future demand of electrical energy of the customers is crucial. The follow-up costs are also low. Finally, it should be noted that there exists no universal approach due to the advantages and disadvantages of each network expansion option. Yet for every network situation the appropriate network expansion option can be selected by considering the environmental conditions. If a single customer is connected via a long supply line and with low short circuit power then the 950-V-line is a feasible solution. If the criteria are sufficiently short-circuit power and customer-cased flicker and harmonics are small, the network controller can be used without difficulty. The network controller can also be considered for small local networks, due to the different offered devices. Are very isolated estates to supply, often the only possibility is a connection to the medium-voltage grid. (orig.)

    The overall objective of the project is to develop a general simulation environment for program systems used in reactor safety analysis. The simulation environment provides methods for graphical modeling and evaluation of results for the simulation models. The terms of graphical modeling and evaluation of results summarize computerized methods of pre- and postprocessing for the simulation models, which can assist the user in the execution of the simulation steps. The methods comprise CAD (''Computer Aided Design'') based input tools, interactive user interfaces for the execution of the simulation and the graphical representation and visualization of the simulation results. A particular focus was set on the requirements of the system code ATHLET. A CAD tool was developed that allows the specification of 3D geometry of the plant components and the discretization with a simulation grid. The system provides inter-faces to generate the input data of the codes and to export the data for the visualization software. The CAD system was applied for the modeling of a cooling circuit and reactor pressure vessel of a PWR. For the modeling of complex systems with many components, a general purpose graphical network editor was adapted and expanded. The editor is able to simulate networks with complex topology graphically by suitable building blocks. The network editor has been enhanced and adapted to the modeling of balance of plant and thermal fluid systems in ATHLET. For the visual display of the simulation results in the local context of the 3D geometry and the simulation grid, the open source program ParaView is applied, which is widely used for 3D visualization of field data, offering multiple options for displaying and ana-lyzing the data. New methods were developed, that allow the necessary conversion of the results of the reactor safety codes and the data of the CAD models. The trans-formed data may then be imported into ParaView and visualized. The application of 3D visualization shows advantages in transient analyses with very detailed discretization. This is especially true for the analysis of phenomena with strong local differences and the validation of multi-dimensional models.

    The author attempted to develop a tool for economic and ecological design of regional waste management networks. His investigation was based on the current attempts at developing regional solutions at minimal cost, which are modified to meet the desired goal and will include a method for regional environmental assessment. [German] Neben der Wirtschaftlichkeit ist entsprechend der im Kreislaufwirtschafts- und Abfallgesetz verankerten Regelungen auch die Umweltvertraeglichkeit von Verwertung, Abfallbeseitigung und Abfallvermeidung gefordert. Zur Entscheidungsunterstuetzung bei der strategischen Planung zukuenftiger Entsorgungskonzepte sind somit Instrumente erforderlich, die es ermoeglichen, auf regionaler Ebene firmenuebergreifende Entsorgungsstrukturen zu entwickeln sowie diese oekonomisch und oekologisch im Sinne des KrW/-AbfG zu optimieren und zu bewerten. Derartige umfassende Planungsinstrumente zum Stoffstrommanagement stehen derzeit nicht oder nur in Ansaetzen zur Verfuegung. Fuer die vorliegende Arbeit wurde die Entsorgung von kommunalem Klaerschlamm in Baden-Wuerttemberg als Untersuchungsgegenstand ausgewaehlt. Ziel der vorliegenden Arbeit ist es, ein Planungsinstrument zur oekonomischen und oekologischen Ausgestaltung standortuebergreifender Entsorgungsnetzwerke zu entwickeln. Ausgangspunkt dafuer sind bisherige Ansaetze zur Entwicklung kostenminimaler regionaler Gesamtloesungen, die an die geschilderte Problematik angepasst und die in geeigneter Weise um eine Methodik zur umweltbezogenen Bewertung erweitert werden sollen.

    Materials and Methods: Twenty of the first 26 consecutive patients referred for potential UFE were enrolled in the study. Pre-interventional MRI was used to assess morphologic contraindication to UFE. The embolization procedures were performed from a unilateral femoral approach using 4F selective catheters in straight vessels, >2 mm in diameter, and micro-catheters in smaller and tortuous arteries. The endpoint of the 'flow guided' embolization was defined by reaching the angiography 'pruned tree' appearance and sluggish flow in the main stem of the uterine artery. Assessment of morphologic mid term success was done by MRI 10 days, 3 months, 6 months, 9 months and 1 year after UFE. The clinical mid term success was assessed by having questionaires completed for menstrual bleeding, retention of clinical (symptomatic) benefit and quality of life. Results: Technical success was 100%, with 8 minor (2 post-interventional collapses, 2 hematomas, 4 relevant post-embolizations syndromes, 1 spontaneous expulsion of a submucous myoma) and 3 major complications (1 hysterectomy because of vaginal bleeding for 5 weeks, 1 transient amenorrhea and 1 spontaneous expulsion of myoma with transient bleeding requiring admission). In 17 of 19 patients, MRI showed total fibroid devascularization throughout the entire follow-up. The average shrinkage of the dominant fibroid was 71.3% at one year. The menstrual bleeding record in the cohort group fell from an average of 501.6 before treatment to 76.2 points at one year. At the same time, the clinical symptoms significantly improved. The patient satisfaction with the applied therapy was >95% at 1 year. One patient with residual fibroid perfusion underwent a second procedure, which achieved complete devascularization and adequate clinical success at one year. The second patient with incomplete devascularization had a persistent clinical benefit. (orig.)

    Since the implementation of the EEG in Germany the biogas production becomes an independent branch of industry in the agriculture. At this time more than 90 percent of the biogas plants work with co-generation plant for heat and power with a thermal engine efficiencies of more than 50 percent. Because of the location in the rural area heat costumers with a continuous demand of heat over the whole year are rare. This research had a closer look how to use the heat of biogas production efficiently and also generating profit. The aim of the study was to use heat over the whole year, a profitable heat concept without counting the KWK-bonus and an added value on the farm. During the study the following concepts were analyzed: asparagus production using soil heating, drying equipment for different products, the production of fish in aquaculture, the poultry production and the heated production of tomatoes. The results showed different concepts using heat of biogas plants as efficient for farmers. However with only one concept the aims - to use the heat over the whole year, generating a profitable heat concept without counting the KWK-bonus, add an value on the farm - mostly can not be achieved. The combination of different heat concepts is necessary. In this analysis the poultry production in combination with the dryer can be considered as the most efficient concept. Bearing in mind the benefit which can be generated with a heat concept as well as the higher income and the higher technical efficiency of biogas plants operators should implement an individual concept for their heat.

    Hydrothermal Carbonisation (HTC) is an innovative process to convert biogenic residual materials from municipalities into high-quality biogenic solid fuels (charcoal). However, this entails increasing fuel costs. Especially high capital costs and a lower capacity factor of innovative processes as well as the pelletising of the charcoal are the main cost drivers. Hence an on-site utilisation of the charcoal without pelletising, e.g. for heat generation, has a high cost reduction potential. Due to the higher capital costs of solid fuel boilers and fuel storage compared to oil and gas boilers, a high degree of capacity utilisation should be pursued to reduce the fixed cost share and, by this means, lower the levelised costs of heat. Currently, the Hydrothermal Carbonisation conversion process is expensive. Therefore, using the charcoal for heat production is not competitive compared to other fossil or biofuels. The high development and cost reduction potential of this innovative process may have a positive economic impact on future utilisation.

    The Dutch Office of Energy Regulation (DTe) plans to adjust the present regulations with regard to regional electricity network companies. In 2002 an integrated model for pricing and quality regulations is drafted, which is expected to be implemented in 2005. This report serves as input for such a model. Quality is defined in terms of electricity supply disruptions. The aim of the study on the title subject is to determine prices for different types of power supply disruptions. The study is based on a survey among 12,400 households and nearly 2,500 small and medium-sized businesses in the Netherlands. [Dutch] De Dienst uitvoering en Toezicht energie (DTe) is voornemens om de huidige regelgeving ten aanzien van de regionale elektriciteitsnetbedrijven aan te passen. Hiertoe zijn in 2002 verkenningen voor een geintegreerd prijs- en kwaliteitsreguleringsmodel opgesteld, dat naar verwachting begin 2005 worden ingevoerd. Dit rapport dient als input voor het kwaliteitsreguleringsmodel. Kwaliteit is hier gedefinieerd in termen van stroomonderbrekingen. Het doel van het onderzoek is om prijskaartjes vast te stellen voor verschillende soorten stroomonderbrekingen. Zo kunnen de onderbrekingskosten verschillen afhankelijk van bijvoorbeeld het tijdstip (dagdeel, dag van de week, seizoen), de duur van de onderbreking, het wel of niet ontvangen van een waarschuwing vooraf en het aantal onderbrekingen. Het onderzoek is gebaseerd op een enquete onder 12.400 huishoudens en bijna 2500 MKB-bedrijven.

  1. Green house gas emissions in German agriculture. Sources and technical reduction capacities under special consideration of biogas; Treibhausgas-Emissionen in der deutschen Landwirtschaft. Herkunft und technische Minderungspotenziale unter besonderer Beruecksichtigung von Biogas

    Energy Technology Data Exchange (ETDEWEB)

    Wegener, Jens-Karl

    2006-12-15

    This monograph is concerned with different aspects of green house gas (GHG) emissions in agriculture. The first part summarizes the total amount of GHG emissions and analyses them regarding their composition. A differentiation is made between the emissions which are already linked to agriculture (source group agriculture: ''digestion'', ''manure-management'' and ''agricultural soils'') within the ''National Report on GHG Emissions'' and those which can be counted primarily in addition to agriculture (''energy'' and ''land use and land use change''). Depending on which database is used, agriculture is participating in emitting green house gases with 6.3% or 11.1% of total German GHG emissions in 2004. This means that agriculture is an important polluter. The development of GHG emissions in agriculture compared to the year 1990 is -18.5% for the source group agriculture. This means that the source group has reduced more emissions than the average (-17.5%) over all domains published within the National Report. Regarding the sources ''energy'' and ''land use and land use change'' in addition emission reduction is -16.4% in the same period and thus worse than the average. Moreover, realized emission reductions are predominantly based on structural changes, less on systematical measures. This fact raises the question how agriculture can make a contribution to the reduction of GHG emissions in future particularly with regard to higher aims in climate politics. For this reason the second part of the monograph identifies capacities for the reduction of GHG emissions by using available agricultural biomass for energetic purposes. Due to the heterogeneity of biomass and the variety of its possible products, a lot of technical processes concerning the conversion of biomass into energy exist in practice. Since all of them have different emission factors the derivation of realistic reduction capacities is a nontrivial problem. This work restricts the problem by combining existing biomass with those technologies which provide largest benefit concerning the reduction of GHG emissions. Thereby it is possible to evaluate the maximum contribution of GHG reductions from biomass usage in agriculture in Germany, which aggregates up to 50,341 Gg CO{sub 2}-equivalent. This means that 78.3% of the emissions from the source group agriculture in 2004 could be compensated if biomass was used within those technologies which produce the largest benefit. In this regards the subsidy of energy crops in biogas plants based on the ''Erneuerbare Energien Gesetz'' (renewable energy law) in Germany should be reviewed because there they do not produce the largest benefit. Energy crops should be applied to replace solid fuels instead. Since in practice several biogas plants are already using energy crops as input material without having an option for alternatives, the question raises how this fact can be improved for the future regarding climate protection. Therefore the third part of this monograph analyses the possible emission reductions of different technologies for converting biogas into energy. Objects of investigation are existing technologies like block heat and power plants or direct gas feeding into public gas distribution system as well as future technologies like the application of biogas in different types of fuel cells. Although direct gas feeding has a better ratio concerning the conversion of primary to secondary energy the GHG reduction capacity is much less compared to technologies of cogeneration. The reason for this is that the production of electricity has much more effect on GHG emissions than the production of heat. This is to be seen when comparing the emission factors of certain reference systems used in this part like condensing boilers running with natural gas (253 gCO{sub 2}/kWhheat), gas steam power plants (432 gCO{sub 2}/kWhel) and the average emissions factor of German power production (653 gCO{sub 2}/kWhel). The more electricity is produced by a conversion technology based on biogas, the higher is its GHG reduction capacity. Direct gas feeding is not the most efficient way of using biogas in matters of climate protection considering that only 13% of the natural gas in Germany is used for electric purposes and considering that replacing natural gas by biogas means that the part of fossil fuels with lowest emissions is replaced. Direct gas feeding is not even then the most efficient way of using biogas if there is a consumer at the other end of the public gas distribution system who theoretically uses the injected biogas for running cogeneration systems. The conditioning of biogas in order to feed public distribution combined with additional heat source for running the fermenter of the biogas plant is worse for efficiency. Considering ecological standpoints local heat and power production next to the fermenter is the most efficient way of using biogas in matters of climate protection. This can only be improved by using more efficient systems like fuel cells instead of existing block heat and power plants. (orig.)

    From June 1991 to 9/92 a total of 28 patients suffering from peripheral (n=20) or centrally (n=8) located soft tissue sarcomas were treated. Tumor resection with negative margins was performed in 20 patients, positive margins remained in 5 patients, and gross macroscopic residual disease in 3 patients. Combined intraoperative and external beam radiotherapy was applied in 22 patients, using IORT doses of 10-20 Gy and an external beam dose of 26-50 Gy. Three patients were irradiated intraoperatively twice with a time interval of 24 h. After a median follow-up of 9.9 months, 20 patients are disease free. Two patients died 4 and 5 months after the end of the therapy with rapidly progressive distant metastases. So far, there have been no IORT infield failures. Mild sensory neuropathy occurred in 1 patient 7 months after treatment. Overall only mild and reversible postoperative and posttherapeutic complications were seen. Based on the retrospective analysis of the target volumes chosen during this working period, a set of horse-shoe-shaped cones was designed, which permitted circular and longitudinal target volumes with a homogeneous dose to be delivered as well. With this dedicated IORT facility simple and safe application of a high boost dose is possible. Further, a clear definition of the target volume, followed by an exact verification and at least integration of this target volume in a three-dimensional treatment plan, is necessary. (orig./Mg)

    Desk research (analysis of the production figures of concrete) and field research (personal discussions with producers and merchants) are carried out to investigate whether the application of fly ash in the production of concrete is feasible. The introduction of fly ash depends on the properties of the final product and of the properties during the process of curing, and these depend on a large number of factors such as cement/sand ratio, quality of cement, specifications of the final product. Products such as paving stones, tiles and blocks are favourable for the application of fly ash in concrete. Building elements, pipes and floor elements are not. Market structure in The Netherlands is outlined and mapped, and the present use of fly ash in the concrete industry is discussed. (In Dutch)

    Climate change constitutes a huge challenge for humankind. Greenhouse gas emissions are still continuing to increase on a global scale. In order to limit the risks of global climate change, global average temperature must not rise more than 2 C above pre-industrial levels by the end of this century. If this target is to be achieved globally, Germany - like the other industrialised countries - must reduce its emissions of greenhouse gases by 40% by 2020 and by 80% by 2050 compared to 1990 levels. The German Federal Environment Agency (Umweltbundesamt, in short ''UBA'') banks on a sustainable climate protection policy through emission prevention and is therefore demanding that, as a priority, the change initiated in German energy policy - away from fossil fuels towards renewable energy sources and a marked increase in energy efficiency - should be consistently implemented and intensified, i.e. that emissions be addressed before they occur. For a limited time, there may also be a need to take end-of-pipe measures to reduce CO{sub 2} emissions. This may include certain forms of capture and storage of the most important greenhouse gas, carbon dioxide, often referred to as CO{sub 2} ''sequestration''. Although CO{sub 2} capture and storage does not prevent continued generation of greenhouse gases, it does promise to prevent their escaping into the atmosphere and, thus, their climate impact for extended periods of time. The Federal Environment Agency takes the view that for the use of such methods it is essential to also take into account their impact on other spheres of the environment and health issues. The Agency has developed a detailed opinion on these issues in a comprehensive position paper, which is available from October 2006 in German on the internet website of the German Federal Environment Agency www.umweltbundesamt.de/energie. This summary outlines the major conclusions. Both national and international aspects need to be considered in the discussion. Where national aspects are concerned, the Federal Environment Agency focuses on the situation in Germany, e.g. in addressing the question of available storage capacity for captured CO{sub 2}. This paper deals only with CO{sub 2} capture and storage, and not with biological (''terrestrial'') sequestration through, for example, forestation. (orig.)

    In the course of the research and development project RS1539 funded by the German Federal Ministry for Economics and Energy (BMWi) the methodology for the automated integration of hazards in Level 1 PSA models has been enhanced. Thereby, the analysis tool pyRiskRobot provides the methodological framework for mapping a generic spectrum of internal and external hazards onto complex PSA plant models. The reimplementation of the software tool via the programming language python extends the applicability and facilitates the handling of pyRiskRobot in comparison to the previous Ruby-based version RiskRobot. Moreover, the development of functions to perform the topological modelling of fault trees and the probabilistic specification of modified fault tree elements have been continued. Due to the reimplementation and further developments, the tool enables to systematically generate fault trees of varying complexity, to flexibly integrate fault trees in existing PSA models and to automatically duplicate interconnected topologies. Thus, pyRiskRobot allows the efficient and traceable realization of hazard specific, usually laborious modifications of PSA models. In addition, pyRiskRobot has been extended to serve as a functional interface between the data compilations comprising the potential influences of hazards on PSA relevant components and the data base of a PSA plant model. Based on this conceptual design, additional analyses of the data can be carried out prior to the integration within the PSA model topology. The reimplemented functionalities of pyRiskRobot have been validated with respect to reference applications, such as the modelling of an internal fire scenario, against the previous version RiskRobot. The existing method collection for the automated modification of fault tree topologies has been extended based on the requirements for further applications, among others the modelling of an external flooding scenario. The deduced hazard specific modelling approaches have been used to pursue a continuous convergence towards methodologically structured function classes. The performed developments provide the framework to investigate relevant scenarios that need to be addressed in the context of periodic safety reviews and that may require an adequate modelling at a high level of detail. The analysis tool pyRiskRobot provides the necessary methods and practical strategies in order to integrate hazards and hazard combinations in PSA plant models of realistic complexity.

    In the frame of ANSICHT the methodology for the demonstration of safe enclosure for high-level heat generating radioactive wastes is described. The report is based on the safety requirements for final repository concepts and shows a first backfilling and sealing concept that was developed for the final repository site model SUeD. The final repository model SUeD is based on a horizontal line storage concept, the Gorleben (VSG) and ERATO container concept and the mine layout were adopted and adapted to the given conditions. The backfill and sealing concept includes migration barriers, line closures and shaft closures in the frame of a redundant and diverse enclosure system. For all technical and geotechnical barrier components the long-term functional requirements were defined. The backfilling concept of underground cavities considers the variety of possible cavities in the line and infrastructure areas.

    The amount of open data available for hydrology research is continually growing. In the EU-funded project SWITCH-ON (Sharing Water-related Information to Tackle Changes in the Hydrosphere - for Operational Needs), we are addressing water concerns by exploring and exploiting the untapped potential of these new open data. This work is enabled by many ongoing efforts to facilitate the use of open data. For instance, a number of portals (such as the GEOSS Portal and the INSPIRE community geoportal) provide the means to search for such open data sets and open spatial data services. However, in general, the systematic use of available open data is still fairly uncommon in hydrology research. Factors that limits (re)usability of a data set include: (1) accessibility, (2) understandability and (3) licences. If you cannot access the data set, you cannot use if for research. If you cannot understand the data set you cannot use it for research. Finally, if you are not permitted to use the data, you cannot use it for research. Early on in the project, we sent out a questionnaire to our research partners (SMHI, Universita di Bologna, University of Bristol, Technische Universiteit Delft and Technische Universitaet Wien) to find out what data sets they were planning to use in their experiments. The result was a comprehensive list of useful open data sets. Later, this list of data sets was extended with additional information on data sets for planned commercial water-information products and services. With the list of 50 common data sets as a starting point, we reviewed issues related to access, understandability and licence conditions. Regarding access to data sets, a majority of data sets were available through direct internet download via some well-known transfer protocol such as ftp or http. However, several data sets were found to be inaccessible due to server downtime, incorrect links or problems with the host database management system. One possible explanation for this

    Kreislaufwirtschaft einen wichtigen Beitrag leisten. Fuer Deutschland laesst sich hier, trotz der anspruchsvollen Ziele, eine positive Zwischenbilanz ziehen. Insbesondere die positiven oekologischen Effekte der Vermeidung, Verwertung und Beseitigung von Abfaellen sind durch zahlreiche wissenschaftliche Studien belegt. Waehrend sich die Kreislaufwirtschaft in Deutschland gut entwickelt hat, befinden sich viele Laender auf dieser Welt noch am Anfang einer nachhaltigen abfallwirtschaftlichen Entwicklung. Unser Lehrstuhl Abfall- und Stoffstromwirtschaft an der Agrar- und Umweltwissenschaftlichen Fakultaet der Universitaet Rostock engagiert sich seit ueber 15 Jahren im internationalen Technologie- und Wissenstransfer. Die regionalen Schwerpunkte sind dabei der arabische und asiatische Raum (insb. China) sowie seit einigen Jahren die baltischen Laender, Osteuropa und Suedamerika. Oft stand in den Projekten im Vordergrund, wichtige Entscheidungstraeger ueber den Stand der Technik zu informieren sowie moegliche administrative Loesungen und angepasste technische Loesungen gemeinsam zu erarbeiten und zu implementieren. Darueber hinaus wurden klassische F and E-Projekte in den genannten Regionen bearbeitet. Im Rahmen von studentischen Arbeiten wurden auch Studien in weiteren Laendern u.a. in Vietnam und Chile durchgefuehrt.

    concerning gaseous and PM emissions of different old and modern biomass combustion systems over whole day operation cycles are now available. Derived from these data, correlations between burnout quality, particulate emissions as well as particle composition of the PM emissions can be deduced. (orig.) [German] Es ist allgemein bekannt, dass es signifikante Unterschiede bezueglich partikelfoermiger Emissionen von modernen und alten sowie automatisch und nicht automatisch geregelten Biomasse-Kleinfeuerungsanlagen gibt. Die Unterschiede beziehen sich einerseits auf die Hoehe der Partikelemission und andererseits auf deren chemische Zusammensetzung. Um Emissionsfaktoren fuer partikelfoermige Emissionen ueber typische realitaetsnahe Tageslastverlaeufe zu bestimmen und die Feinstaubemissionen chemisch zu charakterisieren, wurde ein Projekt an der BIOENERGY 2020+ GmbH, Graz, Oesterreich, in Kooperation mit dem Institut fuer Prozess- und Partikeltechnik, Technische Universitaet Graz, Oesterreich, initiiert. Fuenf moderne, dem aktuellen Stand der Technik entsprechende, Biomasse-Kleinfeuerungen sowie zwei Altanlagen, die den aktuellen Anlagenbestand widerspiegeln, wurden im Zuge von Testlaeufen an einem Teststand untersucht. Dabei wurden alle relevanten Betriebsparameter der Biomasse-Kleinfeuerungen sowie die im Zuge des Verbrennungsprozesses entstehenden gas- und partikelfoermigen Emissionen kontinuierlich gemessen und aufgezeichnet. Des Weiteren wurden Partikelemissionsproben gezogen und anschliessend chemisch analysiert. Fuer die Testlaeufe wurden typische Tageslastverlaeufe, die den Betrieb dieser Feuerungen in der Praxis abbilden, beruecksichtigt. Dabei wurde zwischen automatisch beschickten und automatisch geregelten Kesseln, manuell beschickten und automatisch geregelten Kesseln sowie manuell beschickten Naturzugoefen unterschieden. Die Ergebnisse zeigen einen deutlichen Zusammenhang zwischen den gasfoermigen Emissionen, die durch unvollstaendigen Gasphasenausbrand (CO- und org

    This PhD thesis represents work done between Aug. 2003 and Dec. 2006 in Reinhard F. Werner's quantum information theory group at Technische Universitaet Braunschweig, and Artur Ekert's Centre for Quantum Computation at the University of Cambridge. My thesis falls into the field of abstract quantum information theory. This work investigates both fundamental properties of quantum channels and their asymptotic capacities for classical as well as quantum information transfer. Stinespring's theorem is the basic structure theorem for quantum channels. It implies that every quantum channel can be represented as a unitary evolution on an enlarged system. In Ch. 3 we present a continuity theorem for Stinespring's representation: two quantum channels are similar if and only if it is possible to find unitary implementations that are likewise similar, with dimension-independent norm bounds. The continuity theorem allows to derive a formulation of the information-disturbance tradeoff in terms of quantum channels, and a continuity estimate for the no-broadcasting principle. In Ch. 4 we then apply the continuity theorem to give a strengthened no-go proof for quantum bit commitment, an important cryptographic primitive. This result also provides a natural characterization of those protocols that fall outside the standard setting of unconditional security, and thus may allow secure bit commitment. We present a new such protocol whose security relies on decoherence in the receiver's lab. Ch. 5 reviews the capacities of quantum channels for the transfer of both classical and quantum information, and investigates several variations in the notion of channel capacity. Memory effects are then investigated in detail in Ch. 6. We advertise a model which is sufficiently general to encompass all causal automata: every quantum process in which the outputs up to any given time t do not depend on the inputs at times t'>t can be represented as a concatenated memory channel.

    For a short time now, the L-LAB (Light-LABoratory), a joint research facility of Hella KG and the University of Paderborn, has had a simulator available which allows the evaluation of driver assistance systems and the optimisation of man-machine interfaces. It is an interactive night driver simulator, which can be used to visualise any type of headlamp beam pattern true to the original. A Smart is used as the input medium; image projection is via a 3-channel high-performance beamer projection system onto large screens. Alongside synthetic roads, there is also a digitalised course available, approx. 10 km long, the original of which is actually used by Hella as a proving ground. Road safety indicators can be recorded directly and indirectly. For example, obstacles which suddenly appear force drivers to apply the brakes. The stopping distance required can be interpreted as a direct indicator for safety. In addition, an eye tracking system is used to record the eye movements of the test subjects, which allows additional road safety indicators to be derived. Comparative investigations between the digitalised proving ground and reality allow validation of the simulator. This year, a comprehensive study will be made to optimise the man-machine interface in connection with infrared vision systems in vehicles. The advantages of simulation are not only in the economical implementation possibilities and control of the variables, but also the fact that properties of driver assistance systems can be evaluated which are not even technically possible yet in reality. The use of the simulator developed here is not limited to tests connected with the visibility of obstacles, however. Rather, it allows the investigation and evaluation of a large range of potential driver assistance systems. (orig.)

    Within the work presented here, a new cryostat-module for the superconducting injector accelerator of the S-DALINAC as well as three superconducting cavities have been designed and built. The aim of these efforts was an increase in energy behind the injector from 10 MeV to 14 MeV and in beam current from 60 μA to 250 μA. Such an upgrade in intensity required an increase of the input radio-frequency (RF) power from 500 W to 2 kW. For this purpose new RF power couplers had been designed at the Institut fuer Theorie elektromagnetischer Felder at the Technische Universitaet Darmstadt. In order to enable the use of these couplers a new cryostat-module with a WR-284 rectangular waveguide transition line through all pressure and temperature stages was developed within the work presented here. The new construction was designed following that of the standard cryostats of the S-DALINAC. Because the dimensions and adapters for the beam and insulating vacuum as well as the connections needed for helium and nitrogen supply of both cryostats agree, the present module can be simply replaced by the new one. For the WR-284 waveguide feed-through the tower section was redesigned to provide enough space for an assembly under clean-room conditions. The waveguide bellows, specially built for this project, show excellent RF properties and provide the flexibility needed for the transfer line. As an alternative to a cold vacuum window a special waveguide with diaphragms at an intermediate temperature has been developed in order to minimize losses due to heat radiation inside the waveguide. All waveguide components were tested for ultra-high-vacuum capability and their RF properties have been determined within this work. Within the process of the fabrication of the cryostat module the helium vessel was equipped with a significantly improved magnetic shielding. Final measurements inside the helium vessel showed an average value of 4 μT for the magnetic field at the positions of the

    In the First Technical Report the fundamental ideas for the realization of this project are presented and the future possible maximum gross employment effects of an expansion of renewable energy systems in North-Rhine-Westphalia with consideration of the present-day cost structure are quantified in an initial stage. In this connection gross employment effects are defined as exclusive positive job effects without consideration of possible negative employment effects on the basis of less investments in other sectors of the economy. Based on a subdivided presentation of the intended course of the project and a formulation of its main objectives, a detailed description of the theoretical background of the applied methods of input-output analysis is provided. After the presentation of some different methods and the necessary assumptions, the analysis takes the so-called `Keynesian income multiplier` into account to accommodate the effects of an increase in national income. To use a known investment distribution, grouped in 21 sub-divisions according to categories of applications, within the scope of an input-output-analysis, the investments are converted. After the determination of the matrices, necessary to quantify employment effects, the maximum possible gross effects concerning the future job market of the Federal Republic of Germany will be assessed with consideration of the fluctuations in productivity on sector level. A total of 700.000 new jobs can be expected, of which about 27% are due to the increase of personal disposable income and the resulting rise in consumer spending respectively. (orig./UA) [Deutsch] Im vorliegenden 1. Technischen Fachbericht werden konzeptionelle Grundlagen zur Realisierung des Vorhabens eroertert und es wird eine erste Abschaetzung der potentiellen Bruttobeschaeftigungswirkungen eines Ausbaus erneuerbarer Energiesysteme in Nordrhein-Westfalen durchgefuehrt. Unter Bruttobeschaeftigungswirkungen werden dabei ausschliesslich positive Arbeitsplatzwirkungen ohne Beruecksichtigung moeglicher negativer Beschaeftigungseffekte aufgrund von Minderinvestitionen in anderen Wirtschaftsbereichen verstanden. Im Anschluss an die gegliederte Darstellung des geplanten Projektablaufs und Formulierung der einzelnen Zielsetzungen wird die fuer die Untersuchung notwendige Methode der Input-Output-Analyse vorgestellt. Neben der Erlaeuterung verschiedener Modelle und der notwendigen Annahmen wird die gewaehlte Analysemethode um den sogenannten `Keynes`schen Einkommensmultiplitkator` erweitert, um auch Auswirkungen eines erhoehten privaten Konsums zu beruecksichtigen. Eine nach 21 verschiedenen Nutzungsarten gegliederte Investitionsverteilung wird daran anschliessend zusammengefasst und fuer die Verwendung im Rahmen einer Input-Output-Analyse umgerechnet. Nach der Bestimmung der fuer die Quantifizierung der Beschaeftigungswirkungen notwendigen Berechnungsmatrizen koennen schliesslich die fuer den bundesdeutschen Arbeitsmarkt zu erwartenden Bruttobeschaeftigungseffekte in erster Naeherung ermittelt werden, wobei sektorielle Produktivitaetsaenderungen bis zum Zeitpunkt der Investitionen beruecksichtigt werden. Es ergeben sich insgesamt rund 700.000 neue Arbeitsplaetze, von denen etwa 27% auf die Erhoehung der verfuegbaren Einkommen bzw. den damit verbundenen Anstieg des privaten Konsums zurueckzufuehren sind.

    The previous technologies for the development of the decentralized combined heat and power generation are based on various concepts with different ripeness. Gasification is regarded as an energetically promising technology, which is not yet marketable. Under this aspect, the author of the contribution under consideration reports on an economic evaluation of the decentralized power and heat production by gasification of biogenic solid fuels and on a comparison with existing alternative technologies of combustion. In particular, the author examines the following central issues: (a) Which technologies of gasification can be regarded as promising with respect to a decentralized application?; (b) How are the technologies of gasification to be evaluated with respect to the alternative technologies of combustion from technical and economic view? For the comparative view of these different techniques, an electrical output of 500 W is specified as a uniform characteristic value of performance according to the decentralized gasification and combustion.

    The standby consumption of electrical households and office appliances continues to be significant world-wide since the number of products with standby componen ts is constantly increasing. For Germany, a recent assessment of the Fraunhofer ISI (Cremer et al. 2003) for 2001 arrived at an electricity demand of almost 15 TWh for household and office appliances in standby mode. i.e. in standby and off -mode. This represents almost 40% of the total consumption of these appliances and around 3% of the total electricity demand of the final energy sectors in Ge rmany. The standby share in electricity demand is over 80 or even 90% for numer ous appliances. The Federal Environmental Agency calculated that every year stan dby losses in German households and offices are responsible for wasted electrici ty amounting to 3.5 billion Euro (UBA 2004). For the OECD countries, field studi es show that between 3 and 13% of the electricity consumption of households can be ascribed to standby losses (IEA 2001). Without energy policy measures on bot h national and international levels, there is a great risk that a further increa se in standby consumption will occur. Many studies dealing with this subject hav e already been conducted and have shown that low standby consumption is technica lly feasible and usually achievable at a reasonable cost. One possible energy po licy measure to reduce the standby consumption of electrical household and offic e appliances is the introduction of mandatory consumption labelling. In principl e, a high degree of effectiveness is attributed to such regulatory/command-and-c ontrol measures with regard to influencing the energy efficiency of devices. Com pulsory energy labels to identify and, where necessary, to classify electricity consumption produce greater market transparency and offer buyers an additional d ecision criterion. In this way they promote indirectly the development, producti on and supply of energy-efficient products. When combined with comparatively low implementation costs, the cost-benefit ratio is also relatively good compared w ith other measures. Up until now, compulsory energy labels have been used global ly mainly to indicate the consumption in normal operating mode, primarily for la rge electrical domestic appliances and other devices used predominantly in house holds such as water heaters, lighting or air conditioning devices.

    Purpose: To develop a model for simulation the CT morphologic situation of acute pulmonary embolism, to evaluate the accuracy of spiral CT and 3D reconstruction in the detection of artificial emboli and to investigate the influence of the orientation of emboli depending on z-axis orientation. Materials and Methods: Standardized artificial emboli made of wax and of defined size and shape were positioned into the pulmonary arteries of porcine lungs. Castings of the embolized pulmonary arterial trees were made by injection of a special opaque resin. After performance of spiral CT the data sets of the emboli and the pulmonary arteries were post-processed. The 3D segmentations were compared with the anatomic preparation to evaluate the accuracy of spiral CT/3D reconstruction-technique. Technical specimens simulating CT-morphology of acute embolized vessels underwent spiral CT in six different positions with respect to the z-axis. The CT data were reconstructed using a standardized and a contrastadapted method with interactive correction. The 3D emboli were analysed under qualitative aspects, and measurements of their extent were done. Results: In nearly 91%, there was complete agreement between CT and the corresponding findings at the anatomical preparation. Measurements of the 3D reconstructed technical specimens showed discrepancies of shape and size in dependence of the size of the original preparation, orientation and reconstruction technique. Overestimation up to 4 mm and underestimation to 2,2 mm were observed. Measurements of preparations with heights from 14 to 26 mm showed variances of {+-}1,5 mm ({proportional_to}6-11%). Conclusion: The presented models are suitable to simulate CT morphology of acute pulmonary embolism under ex-vivo conditions. Accuracy in the detection of artificial emboli using spiral CT/3D reconstruction is affected by localization, size and orientation of the emboli and the reconstruction technique. (orig.) [German] Ziel: Die Entwicklung von Modellen zur Evaluierung der Spiral-CT und 3D-Rekonstruktion im Nachweis der akuten Lungenembolie (LE) im Ex-vivo-Experiment. Material und Methoden: Standardisierte kuenstliche Emboli definierter Groesse und Geometrie wurden in Schweinelungen eingebracht. Ausguesse der embolisierten Gefaessbaeume mit roentgenkontrastgebendem Kunstharz simulierten das CT-morphologische Vollbild einer Lungenembolie. Die Bilddaten wurden dreidimensional rekonstruiert und die Exaktheit der detektierten Emboluslokalisation durch Korrelation mit dem Originalpraeparat verifiziert. Messungen an technischen Probekoerpern mit eingeschlossenen Emboli definierter Groesse sollten die Messgenauigkeit der kombinierten Spiral-CT-/3D Rekonstruktion in Abhaengigkeit von deren Orientierung zur z-Achse und von der Rekonstruktionstechnik (standardisiert und kontrastadaptiert) aufzeigen. Ergebnisse: Fuer die Detektion und Lokalisation ergab sich eine Uebereinstimmung zwischen Spiral-CT-/3D-Rekonstruktion und dem Originalpraeparat von {proportional_to}91%. Die Messungen der technischen Probekoerper ergaben deutliche Abweichungen in Abhaengigkeit von der Groesse, der Orientierung zur z-Achse und der Rekonstruktionstechnik. Hierbei traten Ueberschaetzungen von bis zu 4 mm, Unterschaetzungen von bis zu 2,2 mm auf. Bei Praeparaten mit Hoehen von 14-26 mm traten Schwankungen in einer Groessenordnung von ca. {+-}1,5 mm ({proportional_to}6-11%) auf. Schlussfolgerung: Die vorgestellten Ex-vivo-Modelle sind zur Simulation der akuten Lungenembolie gut geeignet. Die Genauigkeit der Embolusdetektion wird durch Lokalisation, Groesse, Orientierung und Rekonstruktionstechnik beeinflusst. (orig.)

    Within the BMUB project 3614R01520 with a term from 01.12.2014 to 31.05.2017, GRS has continued its work on the analysis and evaluation of nuclear safety, radiation protection and the effectiveness of regulatory systems abroad. This was done both by means of our own scientific and technical investigations as well as by our participation in international activities on questions of nuclear safety abroad as well as by tracking the development of selected new reactor concepts and the regulatory framework. The collection, elaboration, further development and maintenance of the necessary knowledge with regard to of nuclear safety abroad (particularly in Eastern Europe and INSC partners) was systematically continued. Other work packages were focused on the adaptation and pilot application of modern analytical methods and GRS programs to reactor plants of Russian design, as a rule together with competent partner organizations from the respective countries, as well as on the conceptual development of knowledge management methods and cooperation platforms. This work also included the pilot testing of selected suitable instruments for knowledge management. The present final report summarizes the results obtained in the 17 work packages of the project.

    There is a large number of different configurations for the combination of a closed cycle gas turbine (CCGT) system and a high-temperature gas-cooled reactor (HTGR). Based on the results of a literature survey an overview of such configurations is presented and a comparison is made for their appropriateness for a small cogeneration system (<60 MWt) to be used in the Netherlands. However, most cycles can only be applied for large-scale energy production or supply heat on a too low temperature level. The direct, recuperated cycle is the only suitable cycle, while that cycle is a simple system and shows an acceptable electric and total efficiency. Calculations were carried out for the co-production of hot water (75-125C and 40-70C) and for steam (10 bar, 220C). By means of a static model and an optimizer the feasible efficiencies for different heat demand are determined. The maximum electric efficiency is 42% for the co-production of hot water and 38% for the co-production of steam. 28 refs.

    )), middle (1000 primaries per RP) and low imaging dose (500 primaries per RP) in the radiographic domain, whereas only high dose tomographic acquisitions were experimentally performed. Dedicated Monte Carlo (MC)-based post-processing methods, developed at the Ludwig-Maximilians-Universitaet Muenchen (Munich, Germany), were applied to improve the retrieval of Water Equivalent Thickness (WET) variations in lateral (spatial resolution) and longitudinal (ion range resolution) directions, for iRADs, and rWEPL in the tomographic case. An exhaustive quantitative and qualitative evaluation of the acquired images was made in comparison with the ground-truth and simulated data in terms of physical-dose to the object [Gy], accuracy [% of Relative Error (RE)] and overall image quality [NRMSD]. iRADs were produced with 0.5 to 1 mGy imaging dose and an absolute mean WET-RE within 1.5%. Tomographies of two heterogeneous phantoms were acquired in the high dose regime, yielding 4 Gy imaging dose and a RE in rWEPL below 1%, for a geometry that resembles an anatomical scenario. Nonetheless, the findings in the low dose projection studies indicate that the dose of tomographic acquisitions with the current experimental setup can be reduced down to 0.2 Gy. Furthermore, the improved readout system tests and MC simulations establish the possibility to decrease the dose received by the imaged object by about one order of magnitude down (∝0.03 Gy), which lies in the clinically accepted range. Finally, the ongoing imaging system upgrade and the potential integration with single-ion tracking detectors is outlined. The outcome of this thesis highlights the strengths and weaknesses of ion transmission-imaging with the investigated integration-mode RRD, paving the way to future improvements towards eventual application to the ion-beam therapy clinical work-flow. Although further optimization is still required for clinical application, ion-based transmission-imaging has demonstrated its potentiality to

    (UT4). Mirrors and Instruments As earlier announced, ESO officially received the first 8.2-metre VLT mirror from REOSC in Paris [3] on November 21. The polishing of the second mirror has already started and, based on the experience gained with the first, it is expected that this work will be accomplished in less time. The third blank is already at REOSC and the fourth will soon be ready at Schott Glaswerke in Mainz (Germany). Following extended studies, and as yet another move towards new technology within the VLT project, it has now been decided to make the 1.2-metre secondary VLT mirrors of beryllium, a very light, exotic metal. The contracting firm is Dornier of the DASA group (Germany). This saves much weight and allows these relatively large mirrors to be efficiently used in the `chopping and tilting' mode needed for observations in the infrared wavelength region as well as for the critical, image-sharpening adaptive optics system. Significant progress has also been achieved on the first astronomical instruments which will be installed at the VLT. The integration of the first two of these, ISAAC and CONICA which will be installed on UT1 in the course of 1997, has already started in the ESO laboratories at the Headquarters in Garching. Important advances have also taken place within the FORS (managed by a consortium of Landessternwarte Heidelberg, Universitaets-Sternwarte Goettingen and Institut fuer Astronomie und Astrophysik der Ludwig Maximilians Universitaet Muenchen) and FUEGOS (Paris Observatory, Meudon Observatory, Toulouse Observatory, Geneva Observatory and Bologna Observatory) projects. More details about these and other VLT instruments will be given in later communications. Notes: [1] The Council of ESO consists of two representatives from each of the eight member states. It is the highest legislative authority of the organisation and normally meets twice a year. This time, Council was invited to Milan by the Director of the Osservatorio di Brera (Milan

    Two new deposition systems were realized enabling the entire and respectively, large area deposition of a-Si:H based solar cells using the so called 'hot-wire' (HW) CVD. The deposition conditions for appropriate n- and p-doped a-Si:H and {mu}c-Si:H layers have been developed. For the first time in the world a-Si:H based pin solar cells were entirely deposited by the HWCVD method. A maximum initial conversion efficiency of {eta}{sub initial}=8.9% was obtained. After the development of a suitable p/n-tunnel/recombination junction pin-pin tandem structures with a-Si:H absorbers could be entirely fabricated by the HWCVD for the first time in the world, too. A conversion efficiency of {eta}=7% was measured for the tandem cell, after some structural degradation took place. In general, the stability of the HWCVD solar cells is not satisfactory, what could be attributed to a structural instability of the HWCVD-p-layers. For the first time we have deposited nip solar cells on stainless steel substrates entirely by HWCVD ({eta}{sub initial}>6%). The incorporation of {mu}c-Si:H absorber layers by HWCVD or ECWR-PECVD into pin solar cells was not successfull until now. Large area deposition of a-Si:H films has been performed in a simple vacuum vessel. Under consideration of appropriate filament and gas supply geometry as well as simulation calculations a good electronic quality and a film thickness uniformity of {delta}d={+-}2.5% of the material was obtained. i-layers for small area solar cells on an area of 20 x 20 cm{sup 2} have been deposited which could be completed to solar cells with very uniform conversion efficiencies of {eta}{sub initial} = 6,1{+-}0.2%. This result represents a proof of concept for the large area deposition of a-Si:H based solar cells using the HWCVD. Also for the first time the HWCVD was used for the deposition of emitter layers on c-Si-wafers to realize hetero solar cells. Hetero solar cells with amorphous, microcrystalline and epitaxial n- and p-type emitters have been fabricated. After a very short development time conversion efficiencies have been obtained ({eta}{sub max} = 15.2%) which are reported for PECVD emitters. (orig.) [German] Zwei neue Anlagen zur vollstaendigen bzw. grossflaechigen Abscheidung von a-Si:H basierenden Solarzellen mit der sog. 'Hot-Wire (HW)' CVD wurden aufgebaut. Die Abscheidebedingungen fuer geeignete n- und p-dotierte a-Si:H- bzw. {mu}c-Si:H-Schichten wurden ermittelt. Weltweit wurde erstmals eine a-Si:H-pin-Zelle vollstaendig mit der HWCVD-Methode hergestellt, ein Anfangswirkungsgrad von {eta}{sub initial} = 8,9% wurde erreicht. Nach Entwicklung eines p/n-Tunnel- bzw. Rekombinationsueberganges ist es weltweit ebenfalls erstmals gelungen, pin-pin-Tandemstrukturen mit a-Si:H-Absorbern vollstaendig mit der HWCVD-Methode abzuscheiden. Nach Teilalterung wurden noch Wirkungsgrade von {eta}{approx}7% ermittelt. Generell ist die Stabilitaet der all-HWCVD-Zellen noch unbedriedigend, was auf strukturell instabile p-Schichten zurueckgefuehrt werden konnte. Erste nip-Solarzellen auf Edelstahlsubstraten wurden ebenfalls vollstaendig mit der HWCVD praepariert ({eta}{sub initial}>6%). Der Einbau von {mu}c-Si:H-Absorberschichten die mit HWCVD bzw. ECWR-PECVD hergestellt wurden, in pin-Solarzellen war bisher wenig erfolgreich. In einer Anlage zur grossflaechigen HWCVD-Abscheidung wurden a-Si:H-Schichten mit guter Qualitaet und einer Schichtdickenuniformitaet von {delta}d = {+-}2,5% hergestellt. Fuer sog. 'Huepfzellen', nur die i-Schicht wurde in der Anlage abgeschieden, wurden auch sehr uniforme Anfangswirkungsgrade {eta}{sub initial}=6,1{+-}0,2% fuer kleinflaechige Zellen auf einer Flaeche von 20 x 20 cm{sup 2} erreicht. Diese Ergebnisse koennen als 'proof of concept' fuer die grossflaechige HWCVD-Abscheidung fuer a-Si:H-basierende Solarzellen betrachtet werden. Erstmals wurde die HWCVD zur Abscheidung von Emitter-Schichten fuer Hetero-Solarzellen auf c-Si-Wafer-Basis eingesetzt. Es wurden Hetero-Solarzellen mit amorphen, mikrokristallinen und epitaktischen n- und p-Typ-Emittern hergestellt. Die Wirkungsgrade erreichten auf Anhieb Werte ({eta}{sub max}=15,2%), wie sie nach laengerer Entwicklungszeit fuer PECVD-Emitter berichtet wurden. (orig.)

    Purpose of this study was to evaluate the outcome of stereotactic body radiotherapy (SBRT) of liver metastases and prognostic factors for local control and overall survival. From 2000 to 2009 74 patients with 91 metastases were treated at the Department for Radiation Therapy and Oncology (TU Muenchen). With an observed local control rate of 75% after 1 year, SBRT proved as an effective local treatment option. Unfortunately, systemic tumor progression still dominates long term survival in many patients.

    : Diffusion maps are a spectral method for non-linear dimension reduction and have recently been adapted for the visualization of single-cell expression data. Here we present destiny, an efficient R implementation of the diffusion map algorithm. Our package includes a single-cell specific noise model allowing for missing and censored values. In contrast to previous implementations, we further present an efficient nearest-neighbour approximation that allows for the processing of hundreds of thousands of cells and a functionality for projecting new data on existing diffusion maps. We exemplarily apply destiny to a recent time-resolved mass cytometry dataset of cellular reprogramming. destiny is an open-source R/Bioconductor package "bioconductor.org/packages/destiny" also available at www.helmholtz-muenchen.de/icb/destiny A detailed vignette describing functions and workflows is provided with the package. carsten.marr@helmholtz-muenchen.de or f.buettner@helmholtz-muenchen.de Supplementary data are available at Bioinformatics online. © The Author 2015.

    A long term safety assessment of a repository for radioactive waste requires evidence, that all relevant processes are known and understood, which might have a significant positive or negative impact on its safety. In 2002, a working group of five institutions was established to create a common thermodynamic database for nuclear waste disposal in deep geological formations. The common database was named THEREDA: Thermodynamic Reference Database. The following institutions are members of the working group: Helmholtz-Zentrum Dresden-Rossendorf, Institute of Radiochemistry - Karlsruhe Institute of Technology, Institute for Nuclear Waste Disposal - Technische Universitaet Bergakademie Freiberg, Institute of Inorganic Chemistry - AF-Colenco AG, Baden, Switzerland, Department of Groundwater Protection and Waste Disposal - Gesellschaft fur Anlagen- und Reaktorsicherheit, Braunschweig. For the future it is intended that its usage becomes mandatory for geochemical model calculations for nuclear waste disposal in Germany. Furthermore, it was agreed that the new database should be established in accordance with the following guidelines: Long-term usability: The disposal of radioactive waste is a task encompassing decades. The database is projected to operate on a long-term basis. This has influenced the choice of software (which is open source), the documentation and the data structure. THEREDA is adapted to the present-day necessities and computational codes but also leaves many degrees of freedom for varying demands in the future. Easy access: The database is accessible via the World Wide Web for free. Applicability: To promote the usage of the database in a wide community, THEREDA is providing ready-to-use parameter files for the most common codes. These are at present: PHREEQC, EQ3/6, Geochemist's Workbench, and CHEMAPP. Internal consistency: It is distinguished between dependent and independent data. To ensure the required internal consistency of THEREDA, the

Middle course sections (3-10 permille), upper course sections (10-100 permille), and steep sections (>100 permille), which are predominantly in notched valleys, can also be found, as typical for low mountain ranges. These areas are less compatible for water retention in meadows. The construction of flood retention basins is recommended. (orig.) [German] In den Jahren 2000 und 2001 wurde von einer Projektgruppe unter Leitung des Fachgebietes Wasserbau und Wasserwirtschaft der Universitaet Kassel im Rahmen der Gemeinschaftsinitiative INTERREG IIC und des Aktionsprogramms IRMA der Europaeischen Union, das Projekt 'Vorbeugender Hochwasserschutz im hessischen Einzugsgebiet der Lahn' (Einzugsgebietsgroesse rd. 4500 km{sup 2}) bearbeitet. Ziel des Projektes war es, in einem wissenschaftlichen Teil ein Hochwasserschutzkonzept des natuerlichen Wasserrueckhaltes ohne grosse Hochwasserrueckhaltebecken zu entwickeln und parallel dazu in 9 Teilprojekten Erfahrung mit der Umsetzung zu sammeln. Die hydrologische und hydraulische Effektivitaet, die Raumwirksamkeit und die Umweltvertraeglichkeit sollten geprueft und eine monetaere Bewertung durchgefuehrt werden. Die Ergebnisse werden in diesem zusammenfassenden Bericht dargestellt. Dazu wurden systematisch die Handlungsvorgaben der drei Strategien 'Natuerlicher Wasserrueckhalt', 'Technischer Hochwasseschutz' und 'Weitergehende Hochwasservorsorge' optimiert. Durch eine integrative Bearbeitung war es moeglich, insbesondere das Retentionspotential in der Gewaesserrenaturierung und in der Talauennutzung, aber auch in Siedlungsgebieten, quantitativ und teilweise monetaer zu erfassen. Breiten Raum nahm auch die Untersuchung der Umweltvertraeglichkeit ein. Als Ergebnis laesst sich feststellen, dass als ueberoertliche Massnahmen der Wasserrueckhalt in Gewaesser und Aue, die Flaechennutzungsaenderung ausserhalb von Ortslagen und der Hochwasserrueckhalt in den Nebentaelern bevorzugt verwirlicht

    As part of an inter-facility comparison of secondary emissions from plasma arc and laser-cutting techniques, standard cutting tests have been done by plasma arc underwater and in air, and by laser beam in air. The same team was commissioned to measure the secondary emissions (solid and gaseous) in each contractor's facility with the same measuring rig. 20 mm and 40 mm thick, grade 304 stainless-steel plates were cut by plasma-torch in three different facilities: Heriot Watt University of Edinburgh, Institut fuer Werkstoffkunde of Universitaet Hannover and CEA/CEN Cadarache. 10 mm and in some cases 20 mm thick, grade 304, stainless-steel plates were cut by laser beam in five different facilities: CEA-CEN Fontenay, CEA-CEN Saclay, Institut fuer Werkstoffkunde of Universitaet Hannover and ENEA/Frascati. The results obtained in the standard experiments are rather similar, and the differences that appear can be explained by the various scales of the involved facilities (semi-industrial and laboratory) and by some particularities in the cutting parameters (an additional secondary gas flow of oxygen in plasma cutting at Universitaet Hannover, for example)

    Temming, H.V.

    2000-05-01

    In cooperation with the Gesellschaft fuer technische Zusammenarbeit GTZ, a school building in Thailand was selected for an analysis of potentials for energy saving. The selected school was the New International School of Thailand (NIST) in Bangkok. Energy-relevant data were acquired by measurements, and solutions for more efficient energy supply were developed. Recommendations were made on this basis. This dissertation is also available on CD-ROM. [German] In Zusammenarbeit mit der Gesellschaft fuer technische Zusammenarbeit GTZ wurde als Beispielobjekt eine thailaendische Schule, die New International School of Thailand (NIST) in Bangkok ausgewaehlt. An diesem Objekt wurden die verschiedenen energetischen Messungen durchgefuehrt. Diese wurden bedarfsgerecht ausgewertet. Auf der Basis der Ergebnisse wurden Loesungsmoeglichkeiten fuer eine effizientere Energieversorgung der Schule konstruiert und diese Alternativen wie oben beschrieben bewertet, woraus sich entsprechende Empfehlungen ergeben. Der Aufbau dieser Arbeit stellt sich nun folgendermassen dar: Nachdem in einem ersten Schritt die fuer diesen Kontext wichtigsten Parameter Thailands und des Untersuchungsobjektes dargestellt werden, schliesst sich hieran die Vorstellung verschiedener technische Alternativen zur Erzeugung von Kaelte an, da hier ein Fokus fuer moegliche Energieeinsparungen gesetzt wird. Anschliessend werden einige in der Arbeit verwandte Berechnungsverfahren fuer energetische oder wirtschaftliche Zuammenhaenge sowie eine ausfuehrliche Beschreibung der energetischen 1st-Situation des Untersuchungsobjektes dargestellt. Darauf aufbauend folgt nun die Vorstellung der verschiedenen Energieeinsparpotentiale durch technische und verhaltensinduzierte Optimierungsmassnahmen. Diese Arbeit endet mit der Bewertung aller aufgedeckten Potentiale und einem Gesamtfazit aus der Untersuchung. (Diese Diplomarbeit liegt auch in Form einer CD-ROM vor.) (orig./AKF)

    Due to stricter efficiency legislation for electrical machines, it becomes increasingly important to predict a motor's performance with regard to start and operational behaviour correctly. In consequence of the higher efficiency required for electrical machines, permanent magnet synchronous machines become an interesting alternative also for motors with direct on-line starting. This paper describes a method to calculate these motor's behaviour reliably and accurately based on a combined analytical and numerical approach developed at the Institute for Drive Systems and Power Electronics of Leibniz Universitaet Hannover.

    The effluents of the radioiodine therapy ward of the Klinik und Poliklinik fuer Nuklearmedizin der Universitaet Wuerzburg are decontaminated by a new plant working by the chromatography principle. The decontamination effect is caused by adsorption of 131 I to activated coal. From January 1992 to September 1993 1280 GBq 131 I were administered to patients. During this period 1028 m 3 of sewage was gathered in the plant corresponding to an input of 0.15 m 3 per patient and day. The water leaving the chromatography plant was contaminated with less than 7 kBq/m 3 131 I. (orig.) [de

    Cattle are commonly infected with pathogenic leptospires, and similarly to rodents, they excrete the bacteria in their urine and can transmit the pathogen from animal to animal or animal to human. Thus, surveillance and monitoring systems for detection of new Leptospira serovars are important for the control of leptospirosis. Here, we report the isolation of a spirochete from a stillborn bovine foetus and its characterization by immunological and molecular techniques. A variable number tandem repeat profile using seven discriminatory primers identified the spirochete as belonging to species Leptospira interrogans serogroup Australis serovar Muenchen. A phenotypic analysis using monoclonal antibodies (mAbs) against leptospiral membrane-associated proteins confirmed the expression of important virulence and pathogenicity factors (LipL32 and LigBrep). Out of 120 reference sera tested, 22 positive (36.66%) and 9 negative (15%) also reacted with the new isolate. Furthermore, the serovar Muenchen isolate was virulent in hamster model. The animal inoculated developed acute lethal infection characterized by hepatic, pulmonary and renal lesions. Local isolates exhibited unique characteristics that differed from those of reference strains; therefore, isolation of leptospires is useful in the surveillance of local pathogenic serovars. In conclusion, the data obtained from this study can contribute to the epidemiological understanding and control of leptospirosis in southern Brazil. Copyright © 2015 Elsevier Ltd.

    A new data acquisition system for the experiment ELAN at the electron stretcher accelerator ELSA had become necessary due to changes in the experimental setup. The data acquisition and analysis which formerly both were performed by a single computer system are now separately done by a VMEbus-Computer and a VAX-Workstation. Based on the software components MECDAS (Mainz Experiment Control and Data Acquisition System) and GOOSY (GSI Online Offline System) a powerfull tool for data acquisition and analysis has been adapted to the requirements of the ELAN experiment. (orig.). [Deutsch] Ziel dieser Arbeit war die Bereitstellung eines neuen Datenerfassungssystems fuer das ELAN-Experiment am Physikalischen Institut der Universitaet Bonn. Als Grundlage hierzu dienten das an der Universitaet Mainz entwickelte System MECDAS und das von der Gesellschaft fuer Schwerionenforschung in Darmstadt stammende Softwarepaket GOOSY. Die Auslese der vom Experiment kommenden Daten wird ueber ein CAMAC-System von MECDAS auf einem VME-Rechner vorgenommen. Dazu wurden in MECDAS neue Auslesealgorithmen eingebettet, die sich teilweise aus experimentellen Notwendigkeiten ergaben und zum anderen den vollen 24-bit Zugriff auf den CAMAC-Bus ermoeglichten. Die gepufferten Daten werden zu einer VAX-Workstation weitergeleitet, auf der sie von GOOSY-Prozessen gesichert und anaylsiert werden. (orig.).

    The demand for continuing improvements of screw machines leads to a vibration research of these machines. The presented paper deals with the experimental measurement of screw compressor operational vibrations and the determination of vibration sources. The measuring of operational vibrations, modal analysis and the determination of mode shape forms of a screw compressor were performed. The main sources of the operational vibrations were determined and the screw compressor eigenfrequencies were found in the frequency spectrum. This contribution forms a basis for the comparison of the theoretical and experimental results. This work was done in cooperation between the University of West Bohemia Pilsen and the Technical University Vienna. (orig.)

    Gasification of biomass followed by power generation from the lean product gas can make a significant contribution to power generation without affecting the climate or environment. It is made even more interesting by the high efficiencies and promising pollution ratings that can be achieved. To make full use of this technology, some technical problems still require solving, and some non-technical obstacles need to be removed. (orig./SR) [Deutsch] Zusammenfassend kann festgehalten werden, dass die Biomassevergasung mit anschliessender Verstromung des Schwachgases einen nennenswerten Beitrag zu einer umwelt- und klimavertraeglicheren Energiebereitstellung in Europa leisten kann. Dies gilt insbesondere vor dem Hintergrund der erreichbaren hohen Stromwirkungsgrade und der vielversprechenden Umweltkenngroessen, durch die diese Technik gekennzeichnet ist. Um die Vorteile der Biomassevergasung realisieren zu koennen, muessen jedoch noch verschiedene technische Probleme geloest und nicht technische Hindernisse aus dem Weg geraeumt werden. (orig./SR)

    As a contribution to the interlaboratory exercise for the complexation of humic acid and colloid generation (COCO-Club activities) in the CEC project MIRAGE-II, the characterization of selected humic acids have been carried out at TU Muenchen, regarding their elemental compositions, inorganic impurities, spectroscopic properties, size distributions and proton exchange capacities. The commercial humic acid (Na salt) from Aldrich Co. is purified to a protonated form and used as reference material. Furthermore two humic acids extracted from groundwaters from Gorleben (FRG) and Boom Clay (B) are purified to protonated forms and taken as site specific materials. These three humic acids, together with the original Na salt from Aldrich Co., are included in the present characterization exercise. The results of characterization provide basic knowledge supporting the forthcoming study of complexation of actinides and fission products with humic acid and their migration processes in the geosphere.

    All forward calorimeters of the ATLAS detector use the same detection technique, energy loss in passive plates, followed by ionisation and charge detection in liquid argon. They are therefore all grouped in the same vessel which must basically support and keep in place the heavy plates and the detection electrodes and maintain liquid argon at cold and stable temperature. Taking into account all the constraints as detailed below, and the overall detector size, 5 meter diameter by 3 meter length this was quite a challenge. The design, construction and tests of these two cryostats, up to their delivery at CERN, are described in this document. These two cryostats are a joint 'in kind' contribution to the Atlas experiment of LAL (Orsay), Max Planck Institute (Muenchen) and Wuppertal University (Wuppertal) and have been designed and built under the responsibility of LAL (Orsay) with contributions of the technical groups of the above institutions and of ATLAS-CERN.

    The report gives a survey of the activities of the Institut fuer Radiometrie of the Gesellschaft fuer Strahlen- und Umweltforschung mbH, Muenchen, in 1974. The long-term studies on flow models were finished, and new groundwater flow models were established on the basis of their results. Apart from apparative and methodical work for isotope hydrology studies, the work on melting processes in snow blankets and the water balance in glacier regions was continued. Plant materials were investigated as a contribution to palaeoclimatical studies. Furthermore, extensive borchole-meter measurements were carried out in some regions in connection with groundwater securing and protection. The knowledge gained so far concerning the hydrological situation of the region was supplemented by tritium measurements in the Asse groundwaters. (ORU) [de

    In May 1980 it was decided to organize an intercomparison of personal dosimeters for photon radiations. The Commission of the European Communities initiated the intercomparison by starting a pilot study in which three laboratories NPL (United Kingdom), PTB (Germany) and RIV (The Netherlands) were asked to irradiate a series of personal dosemeters from institutes, GSF (Muenchen), CEA (Fontenay-aux-Roses), CNEN (Bologna) and CEGB (Berkeley). The latter institutes are secondary standard laboratories and have a radiation protection service as well. A new aspect of this pilot study is the fact that the irradiations also take place in front of a phantom. Irradiations took place in July and August 1980. The results of 4 institutes show that the personal dosemeters are quite capable of measuring the backscattered photon components

    A study was conducted to estimate the prevalence of Salmonella among broilers retailed at wet-markets and processing plants. Litter and feed samples obtained from both broiler and breeder farms were also examined for Salmonella. A total of 158 out of 445 (35.5%) and 52 out of 104 (50.0%) broiler carcasses obtained from wet-markets and processing plants were contaminated with Salmonella, respectively. Salmonella was isolated from 14 out of 98 (14.3%) samples of intestinal content. Litter samples from broiler and breeder farms were positive for Salmonella, 8/40 (20%) and 2/10 (20%), respectively. Salmonella isolates (230) belonging to 15 different serovars were isolated. Predominant serovars were S. enteritidis, S. muenchen, S. kentucky and S. blockley.

    1995-01-01

    A number of different approaches are being used for describing the complexation equilibrium of actinide ions with humic or fulvic acid. The approach chosen and verified experimentally by Tu Muenchen will be discussed with notable examples from experiment. This approach is based on the conception that a given actinide ion is neutralized upon complexation with functional groups of humic or fulvic acid, e.g. carboxylic and phenolic groups, which are known as heterogeneously cross-linked polyelectrolytes. The photon energy transfer experiment with laser light excitation has shown that the actinide ion binding with the functional groups is certainly a chelation process accompanied by metal ion charge neutralization. This fact is in accordance with the experimental evidence of the postulated thermodynamic equilibrium reaction. The experimental results are found to be independent of origin of humic or fulvic acid and applicable for a broad range of pH. (authors). 23 refs., 7 figs., 1 tab

    The purpose of the present study was to prepare, execute, and evaluate a poll among all the operators of solar heating plants promoted by the 'Foerderprogramm Energieeinsparung der Landeshauptstadt Muenchen' (Energy Conservation Promotion Programme for Munich). In the period from 1989 to April 1992 grants of upto 30% of investment costs were accorded by the city administration of Munich for solar heating plants and the technical energy conserving measures, notably high-efficiency boilers and some photovoltaic plants. The principal upper limit for grants was 25,000 DM per one or two-family house plus another 4.000 DM in certain borderline cases. Until early 1992 more than 350 households had made use of the grants offered by the Munich administration through this programme to finance thir solar heating plant. (orig.) [de

    2010-01-01

    A thoron experimental house was constructed in a laboratory room of Helmholtz Zentrum Muenchen to perform exposure studies of thoron and its decay products under controlled conditions. The single room house (7.1 m 3 ) was built from unfired clay stones and clay plaster. For the plaster of the inner side, the clay was mixed with granite powder enriched with 232 Th. The thoron inventory increased by this means to about 1700 Bq and the progeny potential alpha energy to 130 μJ inside the room. The instrumentation of the experimental house includes active and passive devices for thoron and thoron decay product measurement including attached and unattached progeny, for aerosol particle number and size measurement and characterisation of the climatic conditions. Various parameters as ventilation rate and aerosol concentration can be adjusted. Experiments performed in the experimental house demonstrate the experimental power of this new tool for indoor thoron exposure assessment 2010. (authors)

    The City of Munich developed the project 'Munich Energy-Management-Systems (MEMS)' with financial support from the Federal Ministry of Economy and Technology. The project is based on a system of building automation using as many standard elements of hardware and software as possible. This will guarantee a high degree of independence from suppliers and subcontractors. The project has led to a reliable working base for the evaluation, measuring and control for ca. 150 municipal buildings. (orig.) [German] Mit dem Projekt 'Muenchner Energie-Management-System (MEMS)' erstellte die Landeshauptstadt Muenchen mit finanzieller Unterstuetzung des Bundesministeriums fuer Wirtschaft und Technologie ein auf der Leitzentrale Haustechnik (LZH) basierendes zentrales Energiemanagementsystem. Die Verwendung moeglichst vieler Standards in Hard- und Software ist dabei ein wesentlicher Gesichtspunkt. Dadurch wurde eine weitgehende Unabhaengigkeit von einem einzelnen Hersteller erreicht. Damit wurde ein Erfassungs-, Auswerte- und Steuerungssystem fuer derzeit rund 150 staedtische Gebaeude geschaffen. (orig.)

    This work presents a climatology of the northern hemisphere lower and middle stratosphere derived from daily radiosonde observations subjectively analysed in the Stratospheric Research Group of the 'Meteorologisches Institut der Freien Universitaet Berlin'. Previous climatologies from these data were presented by Labitzke (1972), van Loon et al. (1972), and by Labitzke and Goretzki (1982). Although some more recent climatological fields have been presented in several works by members of the group, no complete atlas has been compiled for some time. The work is intended to serve as a reference for people interested in the stratosphere and, particularly, the climate analysis and modelling communities, which require contemporary analyses of the available data in order to interpret their products. In this first part of the climatological atlas, monthly mean data are presented. (orig./KW)

    The reactor safety research contains the analysis of postulated accidents in nuclear power plants (npp). These accidents may involve a loss of coolant from the nuclear plant's reactor coolant system, during which heat and pressure within the containment are increased. To handle these atmospheric conditions, containment spray systems are installed in various light water reactors (LWR) worldwide as a part of the accident management system. For the improvement and the safety ensurance in npp operation and accident management, numeric simulations of postulated accident scenarios are performed. The presented calculations regard the predictability of the containment spray system's effect with the integral code ASTEC and the containment code system COCOSYS, performed at Ruhr-Universitaet Bochum. Therefore the test PACOS Px2.2 is simulated, in which water is sprayed in the stratified containment atmosphere of the BMC (Battelle Modell-Containment). (orig.)

    Angular correlation experiments have been performed on {sup 96}Mo and {sup 98}Mo at the IKP, Universitaet zu Koeln, and at WNSL, Yale University. Lifetimes of excited states have been determined from line shape analyses. The extensive data set, compared to IBM-2 configuration mixing calculations based on microscopic EDFs, reveals the occurrence of coexistence of near-spherical and deformed configurations in both Mo isotopes. Furthermore, the main fragments of one-phonon mixed-symmetry 2{sup +} states have been identified. The systematic of their decay behavior in the Mo chain from N=52 to 56, namely the crossing of the strongest M1 decay branch to the first and second 2{sup +} states as a function of neutron number, suggests a new signature for shape coexistence.

    Analyses of materials with ion beams have proven to be a valuable technique for describing the spatial distributions of specific elements in host materials. We have applied this technique using the 15 N(p, αγ) 12 C reaction to study the time dependence of the chemical reactions involved in the curing of cement. By using the Dynamitron Tandem accelerator at the Ruhr Universitaet, Bochum, Germany, we have been able to achieve a few nanometer spatial resolution at the surface of cement grains and to study the hydrogen distributions to a depth of about 2 μm. By applying a technique for stopping the chemical reactions at arbitrary times, the time dependence of the chemical reactions involving specific components of cement can be investigated. In addition, the effects of additives on the chemical reactions have been studied, as have materials that are components of concrete

    Electricity from geothermal energy in the low temperature range can be efficiently recovered if power plant processes are used with organic working fluids. It is inevitable that a small part of the sometimes harmful fluids leaking from the plant - a conflict in the development of climate-friendly renewable energy actually.

    The thesis reports on the measurement of bremsstrahlung linear polarization produced in collisions of longitudinally and transversely polarized electrons with gold atoms. The experiment was performed at the Mainzer Microtron MAMI in the Institut fuer Kernphysik of Johannes Gutenberg-Universitaet Mainz, Germany. Spin-oriented electrons with 2.15 MeV kinetic energy collided with a thin golden target and produced bremsstrahlung. Linear polarization of the emitted photons was measured by means of Compton polarimetry applied to a segmented high-purity germanium detector. Experimental results reveal a strong correlation between the electron spin orientation and bremsstrahlung linear polarization. This indicates a dominant role of the electron spin in atomic-field bremsstrahlung and Coulomb scattering.

    Many textbooks about radiation therapy for the education of medical, technical and scientific staff are available. But they are restricted to transfer of knowledge via text and figures. On the other hand movies and animated pictures can give you a more realistic impression of the procedures and technical equipment of a radiation therapy department. Therefore, an interactive multimedia teaching program was developed at the Universitaets-Krankenhaus Eppendorf for the department of radiation therapy. The electronic textbook runs under 'MS Windows 3.1 trademark ' (with multimedia extensions) and 'MS Windows 95 trademark ', contains eight chapters and can be used without any preliminary knowledge. The program has been tested by medical personnel, nurses, physicists and physicians and was generally welcome. The program was designed for people with different levels of education to reach as many users as possible. It was not created to replace textbooks but was designed for their supplement. (orig.) [de

    A tracking algorithm for the reconstruction of the daughters of long-lived particles in LHCb 5 Jun 2018, 16:00 1h 30m Library, Centro San Domenico () LHC experiments Posters session Speaker Katharina Mueller (Universitaet Zuerich (CH)) Description The LHCb experiment at CERN operates a high precision and robust tracking system to reach its physics goals, including precise measurements of CP-violation phenomena in the heavy flavour quark sector and searches for New Physics beyond the Standard Model. The track reconstruction procedure is performed by a number of algorithms. One of these, PatLongLivedTracking, is optimised to reconstruct "downstream tracks", which are tracks originating from decays outside the LHCb vertex detector of long-lived particles, such as Ks or Λ0. After an overview of the LHCb tracking system, we provide a detailed description of the LHCb downstream track reconstruction algorithm. Its computational intelligence part is described in details, including the adaptation of the employed...

  12. Behaviour of pathogenic microorganisms and parasites in biogas production from sewage sludge and municipal wastes

    Walter-Matsui, R.; Seipp, M.

    With a grant from VW-Stiftung a project was investigated by the 'Medizinisches Zentrum fuer Hygiene, Philipps-Universitaet, Marburg' and the 'Faculty of Agriculture, Fayum, University Cairo'. The aim was to modify the biogas process to get an optimal amount of biogas and to kill the pathogen bacteria at the same time. The effect of different materials, for example, plant wastes, sewage sludge, cow dung and town refuse and their various amounts of dry matters (2% - 16%) were tested. Also the bactericidal effects of pH, Lactobacilli and higher temperatures were checked. It was found that only a pasteurisation before the fermentation decontaminate the sludge without declining amounts of biogas. It was also proved that the development of Schistosoma eggs was interrupted by the fermentation process.

    The AiF funded research project VESTA continues the development of a fluidized bed combustion system at Universitaet Rostock together with ES+S GmbH and other partners. This paper presents the mechanical design aspects and focuses on the tools developed to simplify customization of the design. The energy system built around a high turbulent fluidized bed combustor can utilize a wide range of fuels. This flexibility, however, involves higher complexity in the design of each individual plant. To allow for a faster engineering process, generic CAD models have been created in Pro/ENGINEER. These models are controlled by dimensioning tools in standard applications, which reduces the amount of work necessary to adapt the design to individual size and operating conditions and to create the required engineering documentation.

    The present joint study performed by the Commissariat a l'energie atomique and the Universitaet Hannover and coordinated by the Commission of the European Communities was intended to analyse the results generated in a number of research contracts concerned with cutting tests in air and underwater, with consideration of the prevailing working conditions. The analysis has led to a large database, giving broadly-assessed information for the dismantling of radioactive components. The range of study was enlarged, where possible, to include recently obtained results outside the present research programme, consideration also being given to supplementary cutting tools and filtration systems not covered by the present programme. Data was concentrated in structured information packages on practical experience available for a series of cutting tools and filters. These were introduced into a computerized user-friendly databank, to be considered as a first-stage development, which should be continuously updated and possibly oriented in the future to an expert system

    The influence of metal-dielectric (MD) layers (MD structures) inserted into the plasma chamber of an electron cyclotron resonance ion source (ECRIS) onto the production of electron bremsstrahlung radiation has been studied in a series of dedicated experiments at the 14 GHz ECRIS of the Institut fuer Kernphysik der Universitaet Frankfurt. The IKF-ECRIS was equipped with a MD liner, covering the inner walls of the plasma chamber, and a MD electrode, covering the plasma-facing side of the extraction electrode. On the basis of similar extracted currents of highly charged ions, significantly reduced yields of bremsstrahlung radiation for the 'MD source' as compared to the standard (stainless steel) source have been measured and can be explained by the significantly better plasma confinement in a MD source as compared to an ''all stainless steel'' ECRIS.

    Title: Using containers with ATLAS offline software Marcelo Vogel, Bergische Universitaet Wuppertal Graeme Stewart, University of Glasgow Johannes Elmsheuser, Brookhaven National Laboratory Lukas Heinrich, New York University Abstract: This paper describes the deployment of ATLAS offline software in containers for software development and the use in production jobs on the grid - such as event generation, simulation, reconstruction and physics derivations - and in physics analysis. For this we are using Docker and Singularity which are both lightweight virtualization technologies to encapsulates a piece of software inside a complete file system. The deployment of offline releases via containers removes the interdependence between the runtime environment needed for job execution and the configuration of a computing site’s worker nodes. Once the two are decoupled from each other, sites can upgrade their nodes whenever and however they see fit. Docker or Singularity will provide a uniform runtime environment fo...

    On October 01, 2009, the Karlsruhe Institute of Technology (KIT) was founded by a merger of Forschungszentrum Karlsruhe and Universitaet Karlsruhe (TH). KIT bundles the missions of both precursory institutions: a university of the state of Baden- Wuerttemberg with teaching and research tasks and a large-scale research institution of the Helmholtz Association conducting program-oriented provident research on behalf of the Federal Republic of Germany. Within these missions, KIT is operating along the three strategic fields of action, research, teaching, and innovation. With about 8000 employees and an annual budget of about EUR 700 million, KIT is one of the largest research and teaching institutions worldwide. It has the potential to assume a top position worldwide in selected fields of research. The objective: KIT will become an institution of excellent research and scientific education, as well as a prominent location of academic life, life-long learning, comprehensive advanced training, unrestricted exchange of know-how and sustainable innovation culture. The largest organizational units of KIT are the KIT Centers. They focus on problems of fundamental importance to the existence and further development of our society or on key issues of basic science. KIT Centers are characterized by the uniqueness of their scientific approach, their strategic objective and mission and by a long-term perspective. The Institut fuer Nukleare Entsorgung, INE, (Institute for Nuclear Waste Disposal) belongs to the KIT Energy Center. The KIT Energy Center comprises some 40 institutes of the Universitaet Karlsruhe (TH) and 18 large institutes of the Forschungszentrum Karlsruhe with, at present, a total of approx. 1100 staff members. The participating institutes and research groups are the operating research units. An interdisciplinary KIT School of Energy establishes ideal framework conditions for teaching.

    The validation and verification of theoretical vehicle dynamic results for autonomous driving can be seen as a major challenge. The main reasons are the high cost of driving tests and the risk of damaging or destroying the test vehicle and the involved persons. One possibility for avoiding these problems and simultaneously to ensure good experimental results lies in the use of scaled model vehicles. Of special relevance is the transfer of relevant parameters to the full size vehicle. In this paper a method based on similitude analysis is developed for validation and verification of driving tests for autonomous vehicles. This method is described for a lane change manoeuvre for a 1:5 scaled vehicle belonging to the Institute of Mechatronics and System Dynamics at the Gerhard-Mercator-Universitaet Duisburg. (orig.) [German] In der autonomen Fahrzeugfuehrung stellt die experimentelle Verifikation und Validierung von theoretischen Ergebnissen hinsichtlich fahrdynamischer Eigenschaften eine grosse Herausforderung dar. Die Ursachen hierfuer liegen zum einen in den hohen Kosten, welche bei Fahrversuchen entstehen, und zum anderen im Unfallrisiko fuer den Versuchstraeger und die am Versuch beteiligten Personen. Eine Moeglichkeit diese Nachteile zu umgehen und gleichzeitig experimentelle Ergebnisse zu bekommen, besteht in der Verwendung massstabgetreuer Modellfahrzeuge. Von besonderer Bedeutung ist hier die Uebertragung relevanter Parameter auf das reale Fahrzeug. In diesem Beitrag wird daher mit Hilfe von aehnlichkeitstheoretischen Ueberlegungen ein Konzept zur experimentellen Verifikation und Validierung von Fahrversuchen auf Basis eines am Institut fuer Mechatronik und Systemdynamik der Gerhard-Mercator-Universitaet Duisburg vorhandenen Fahrzeugmodells (Massstab 1:5) anhand eines Spurwechselmanoevers vorgestellt.
