  15. Karlsruhe Nuclear Research Center, Institute for Meteorology and Climate Research. Progress report on research and development work in 1993

    International Nuclear Information System (INIS)

    1994-03-01

    The Institute for Meteorology and Climate Research is operated by Karlsruhe Nuclear Research Centre in cooperation with Karlsruhe University. It investigates mesoscale and global atmospheric processes. Work on mesoscale processes focuses on interactions between atmosphere, soil and vegetation via the exchange of momentum, energy, water, and materials. Another field of primary interest are the flow processes and turbulent exchange processes in the lower troposphere. Parallel to the experiments, numerical simulation models for describing and predicting mesospheric climate-relevant processes and atmospheric exchange processes were used and improved upon. For remote processing of atmospheric parameters, a satellite-based data processing system was used for recording land surface parameters and vertical profiles and meteorological variables that are applicable for climatological studies and for the validation of numerical models. For recording and interpretation of the spatial and time-dependent distribution of trace elements, measuring instruments in the field of air chemistry were newly developed or improved upon, especially with a view towards high time resolution of the measured data. Ozone research is a key issue of the remote measurements. Contributions were made primarily in the framework of international research programmes (e.g. EASOE) on the degradation of the atmospheric ozone layer in the higher latitudes of the northern hemisphere. In addition to the experimental investigations, the transport of stratospheric trace elements was simulated numerically. (orig./KW) [de

    1995-01-01

    The Karlsruhe Research Center is Germany's largest multidisciplinary research establishment in the fields of natural sciences and technology. In its relatively short period of existence, the Research Center has experienced vivid evolution and modification of original research goals, and even a profound change of the major tasks and goals laid down at the time of its foundation, which most obviously expresses itself in the change of name from Nuclear Research Center into Research Center, effective since January 1995. The wealth of important material accumulated in the archives of the Center throughout the almost 40 years of existence is a treasure for the historian and offered the tempting and useful task to process the material into a historical survey offering the many facettes of the history: in the end, the result combines an important piece of history of technology with the history of the Land of Baden-Wuerttemberg, the region, and the neighbouring city of Karlsruhe. In addition, the publication in hand also offers insight into the sociological aspects of the research work performed in the Center, and the interactive impetus of research and development in the interest of society at large.

  14. Establishing a Research Information System as Part of an Integrated Approach to Information Management: Best Practice at the Karlsruhe Institute of Technology (KIT

    Directory of Open Access Journals (Sweden)

    Frank Scholze

    2012-01-01

    Full Text Available The Karlsruhe Institute of Technology (KIT is one of the largest research and higher education organisations in the world focusing on engineering and natural sciences. At present KIT, under the chairmanship of its executive board, is installing an extensive current research information system (CRIS covering all institutes and facilities of the organisation. The assumption underlying the project is that a consistent overview of research performance has become fundamental for the international competitiveness of research institutions and is increasingly important for strategic decisions at the executive level. Ultimately, it also leads to better data and control in rankings at higher education assessments. The new research information system systematically maps all of KIT’s processes and instruments to obtain, connect, present and utilise the research metadata of active researchers. This reduces the documentation workload for researchers, for the executive level and central units such as the library, and at the same time allows for and facilitates an overall view and the aggregation and visualisation of research metadata. Our vision is to build a federally structured network of systems that gathers information on KIT’s publications, research competence, research projects, patents and technological offers by retrieving data from external and internal sources as well as directly from the researchers. The network facilitates linking and aggregating of data and provides unique identifiers for individual researchers and organizational units. With its consistent data model the research information system also fosters the organisational development of KIT, which was formed in 2009 by the merger of a university and a national research centre. The researchers and their activities are at the core of the research information system. The system substantially reduces their administrative burden in documenting project information and publications. Automatic

  15. Activities at the Institute of Materials and Solid State Research of the Karlsruhe Nuclear Research Centre in the field of fuel pin modelling

    International Nuclear Information System (INIS)

    Elbel, H.

    1979-01-01

    Fuel pin modelling has been pursued at the Institute of Materials and Solid State Research (IMF) of the Karlsruhe Nuclear Research Centre (KfK) with the main objective to provide a detailed quantitative analysis of the fuel pin behaviour in a LMFBR under normal and off-normal operation conditions. The computer programs and models developed at the IMF serve the purpose to aid effectively in the development of an optimized fuel pin concept for a LMFBR. What extent of clad deformation can be tolerated without running into clad failure? What is the influence of neutron dose, temperature, corrosion attack, arid cyclic forces on the state of the clad? What may be the reasons for clad failure? In answering these questions computer programs can play an important role. The activities at the IMF in the field of fuel pin modelling cover the following topics: development of computer programs and models; validation of these programs and models, application to the design of fuel pins for irradiation experiments; assistance in the evaluation of operation data and post- irradiation results, and parametric studies on the influence of design parameters, operation conditions and certain material phenomena on the in-pile behaviour of the fuel pin

    1994-03-01

    The Institute for Nuclear Solids Physics carried out about 90% of its work in the year of the report, 1993, on the main point of superconductivity. The work on high temperature superconductors on a cuprate basis was continued on a large scale. The availability of better samples (eg: non-twinned single crystals) make it possible to clear up a series of important detailed questions regarding the structure, grid dynamics and electronic structure. The activities closely related to applications of superconducting films were concentrated on the growth of a-axis and c-axis orientated films on technically relevant substrates (above all on sapphire, including suitable buffer layers and the examination of these films regarding their high frequency behaviour. Considerable progress was achieved in the manufacture of wafers coated on both sides. The work on Fullerene (carbon molecules C 60 , C 70 etc) and Fullerene compounds was continued. The Institute quickly succeeded not only in preparing these systems, but also in making a considerable contribution to a physical understanding of them. Among the Institute's activities, which are not directly connected to superconductivity (about 10%), one should mention above all, the experimental and theoretical work on the physics of surfaces and boundary surfaces, on polymer physics and on the physics of mesoscopic systems.

    The Institute for Applied Nuclear Physics is presently pursuing basic research-and application-oriented work in the two fields of nuclear solid-state physics and nuclear physics. In the field of solid-state physics the experimental and theoretical work has the purpose of better understanding the microscopic and macroscopic properties of certain solids. At present superconductors with high transition points, amorphous substances and alloys of transition metals and rare earths are investigated with special intensity. The work in nuclear physics concerns on the one hand, the investigation of the local and impulse distribution of nucleous or nucleon groups in nuclei. For this purpose nuclear reactions are investigated at the cyclotron in Karlsruhe and laser-spectroscopic methods are applied to small amounts of radioactive isotope substances. On the other hand, neutron capture cross-sections are measured which are important to understand the element assembly in stars. For the Core Material Control Project one group is developing measuring instruments by means of which the isotope composition and the concentration of fission products can be determined very precisely.

    The Chair in the Theory of Mining Methods and Operations (Deep Mines) at the Institute for Mining at Clausthal Technological University deals with the theory of and research into underground extraction of solid mineral raw materials. With the concentration and concentration of the German mining industry the department has focussed more attention on foreign mining industries and utilisation of the earth's crust in general. The extractive mining industry is augmented by the underground utilisation of cavities for disposal purposes and for infrastructural tasks. Accordingly the courses offered have been extended towards environmental protection and geotechnics. In particular basic research in the field of disposal in mines has become one of the main areas of research in the department not least of all because of the financing from public funds. Theory, research and further training now cover underground extraction in mines, disposal in mines and rehabilitation of contaminated industrial sites. (orig.)

    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 Potsdam Institute for Climate Impact Research was founded in 1992, the year that the Rio Conference was expected to grind out the blue-print for global sustainable development. The Institute`s general philosophy and methodology have been described before (e.g., in the introduction to the first biennal report 1994/95). Here, it is emphasized that the heterogeneity of the scientific tasks to be solved by PIK (ranging from empirical time series analysis to paradigms for ecosphere management) and the complexity of the environmental systems to be investigated call for a specific research strategy, which generally compromises between high-precision analysis and educated guesswork.

    Harde, R.

    1981-01-01

    The Karlsruhe Nuclear Research Center was founded on July 19, 1956. The initial company, in which the Federal Republic of Germany held a 30% interest, the State of Baden-Wuerttemberg 20%, and German industry 50%, was founded mainly for the purposes of building and operating a German-designed research reactor. In 1959, the Gesellschaft fuer Kernforschung mbH was founded for execution of the research and development activities, in which the Federal Republic of Germany held 75%, the State of Baden-Wuerttemberg 25% of the shares. The two companies were merged in 1963, after industry had donated its holdings in the initial company to the new company. In 1972, the financial holdings of the Federal Government were raised to 90%. On January 1, 1978, the company was named Kernforschungszentrum Karlsruhe GmbH (KfK). Over the past 25 years, KfK has received approx. DM 7 billion out of public funds. Important milestones in the development of nuclear technology in the Federal Republic contributed by KfK include the development of the fast breeder line and responsibility for construction of the first German fast breeder reactor, KNK; development of reprocessing technologies and responsibility for construction of the first German reprocessing plant, WAK; development of a uranium enrichment technique (separation nozzle method); important contributions to reactor safety, fusion research, and training in nuclear technology.

  9. The ''Nuclear-Karlsruhe'' air-filter system

    International Nuclear Information System (INIS)

    Berliner, P.; Ohlmeyer, M.; Stotz, W.

    1976-01-01

    Increasing requirements for exhaust-air filter systems used in nuclear facilities induced the Gesellschaft fuer Kernforschung to develop the ''Nuclear-Karlsruhe'' HEPA filter system. This novel development has profited by experience gained in previous incidents as well as by maitenance and decontamination work performed with different HEPA filter systems. The proved ''Nuclear-Karlsruhe'' system takes equally into account the demands for optimum safety, maximum efficiency and economy, and is distinguished by the following features: (1) The air current is defected by 180 0 in the casing. Deflection causes quite a number of improvements, results in substantial reduction of space requirements, and avoids the dispersion of pollutants to the clean-air side. Besides, the HEPA filter is protected from damage by condensed particles or foreign materials entrained; (2) The ''Nuclear-Karlsruhe'' system allows gas-tight filter replacement. Special replacement collars have been provided at the casing, which allow the tight fastening of replacement bags which are self-locking. (3) In-place testing in the operating condition can be carried out very conveniently because the air is deflected. Minimum leaks in the filter medium or in the filter gasket can be detected by the high-sensitivity visual oil-thread test, which makes leaks distinctly visible as oil mist threads through a transparent front window provided on the clean-air side. The test takes only some minutes and its sensitivity is hardly matched by any other technique. (4) The clamping mechanism is installed outside the casing, i.e. outside the polluted or aggressive media. The contact force is spring-loaded absolutely uniformly to the circular filter gasket. (5) For practical and econmic reasons the filter casings can be locked individually so as to be gas-tight. (6) The entire system is made of stainless or coated steel and metal parts which are corrosion and fire-resistant. (author)

    1982-02-01

    The Institute for Reactor Development works chiefly on technical problems as a function of the development and safety evidence of nuclear installations. The tasks that are for a greater part performed together with other internal and external institutions, are both theoretical- and experimental-natured and concentrate mainly on problems out of the reactor safety. The works are in the main concentrated in the 'Fast Breeder Project' (PSB) and in the 'Nuclear Safety Project' (PNS). The PSB-contributions to design and safety of sodium-cooled breeding reactors comprise above all investigations on the thermohydraulic and neutronkinetic behaviour of the core as a result of incidents with very low probability to occur, as well as on the effects of local cooling failures in the reactor core in particular consideration of possible failure propagation mechanisms and of the detectability of such processes. The works in the field of safety of lightwater reactors concern in particular investigations on the dynamic load of component parts of reactor pressure vessels related with the HDR-blowdown-tests and containment structures, as well as investigations on the fuel rod behaviour in the loss of coolant incident.

  2. Results of research and development work in 1982 of the Institut fuer Technische Physik

    International Nuclear Information System (INIS)

    1983-02-01

    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.

  18. Report on results of research and development work carried out in 1979 by the Institut fuer Neutronenphysik und Reaktortechnik

    International Nuclear Information System (INIS)

    1980-02-01

    The activities of the INR concentrate on problems in nuclear technology, especially on problems encountered in the development of sodium-cooled fast reactors. Most of the work is carried out under the roof of projects in cooperation with other institutes or industrial research groups. The studies performed within the fast-breeder project (PSB) relate to reactor physics, design data and safety problems of fast reactors. The environmental impacts of nuclear reactors in case of accidents are investigated by the Institute within the framework of the nuclear safety project (PNS), whereas the problems to be studied for the reprocessing project (PWA) relate to the activity inventary and to instrument development. Another main field of interest is nuclear safeguards, the Institute being concerned with the isotope correlation technique and its application. For the fusion reactor technology project, the research work carried out by the Institute deals with fusion techniques using inertial confinement. (orig./HP) [de

    One of the main goals in mind in 1956 when the Karlsruhe Nuclear Research Centre was founded, was to promote the peaceful uses of nuclear energy in the Federal Republic of Germany. The work accomplished since then by the various institutes of the Centre was particularly successful in the following: Development and construction of the first research reactor as an entirely national achievement; installation and operation of the MZFR reactor, as well as the compact sodium-cooled KNK reactor; the Nuclear Safety Project; the development of the separation nozzle method for uranium enrichment; and specific methods and equipment developed for safeguards systems to prevent nuclear materials diversion. Looking into the future, the tasks ahead will concentrate on the technology of energy generation by thermonuclear fusion, and on environmental pollution control and related methods, as well as industrial processes such as materials handling and process control by PDV and CAD.

  9. Armouring facility? Nuclear-weapon and reactor reseach at the Kaiser-Wilhelm Institute for Physics; Eine Waffenschmiede? Kernwaffen- und Reaktorforschung am Kaiser-Wilhelm-Institut fuer Physik

    Energy Technology Data Exchange (ETDEWEB)

    Hachtmann, R. (ed.); Walker, M.

    2005-07-01

    The Kaiser Wilhelm Institute for Physics is best known as the place where Werner Heisenberg worked on nuclear weapons for Hitler. Although this is essentially true, there is more to the story. At the start of World War II this institute was taken over by the German Army Ordnance to be the central, but not exclusive site for a research project into the economic and military applications of nuclear fission. The Army physicist Kurt Diebner was installed in the institute as its commissarial director. Heisenberg was affiliated with the institute as an advisor at first, and became the director in 1942. Heisenberg and his colleagues, including in particular Karl-Heinz Hoecker, Carl Friedrich von Weizsaecker, and Karl Wirtz, worked on nuclear reactors and isotope separation with the clear knowledge that these were two different paths to atomic bombs [Atombomben]. However, they were clearly ambivalent about what they were doing. New documents recently returned from Russian archives shed new light on this work and the scientists' motivations. (orig.)

The first criteria had a decisive influence on the roof arrangement, as an extension of the neighboring buildings, and on the selection of construction materials to match the suburban environment where the site is located, not to forget the shaping of Windows and skylights, reflecting the internal functions and providing lighting while protecting the privacy of the interior from the exterior lines of view. The second criteria affects aspects so different from one another as the unexpected but valid room arrangement following a spiral path leading from the entrance to the master bedroom at the other end with the remaining rooms at intermediate levels affording the required degree of privacy; or the arrangement of the mechanical installations, resembling the human backbone; or, finally, the paint finish chosen, pleasing man's taste for ornamentality.

    La realización de esta vivienda, en Karlsruhe, estuvo marcada por dos criterios fundamentales: la funcionalidad y la escala humana, llevadas ambas hasta sus últimas consecuencias. La primera influyó desde la disposición de las cubiertas, como prolongación de las construcciones vecinas, hasta la elección de los materiales constructivos, acordes con el entorno suburbano de la parcela, sin olvidar la configuración de las ventanas y lucernarios que, con sus diferentes formatos, indican el uso del interior, al tiempo que posibilitan la iluminación, protegiendo de las vistas exteriores. La segunda característica afecta a aspectos tan dispares como la original, pero válida, secuencia de habitaciones —según una espiral que, desde la entrada, conduce, en el extremo opuesto, al dormitorio de los padres, quedando las restantes dependencias situadas en los niveles intermedios según su exigencia

    2002-01-01

    Active cooperation between seismologists at Bucharest and Karlsruhe started in 1974 with the installation of seismic stations at Romanian dam sites. These stations also recorded the destructive earthquake of 1977 and formed the nucleus for a broader cooperation between seismologists at Bucharest and Karlsruhe and was followed by a continuing exchange of knowledge by vice versa research visits. The cooperation was finally intensively increased by the installation of a major priority research program on earthquake risk problems of Karlsruhe University with Romanian research institutions in 1996, when Romanian and German scientists from various fields (geology, seismology, civil engineering, operation research) organized themselves in the Collaborative Research Center 461 (CRC 461) 'Strong earthquakes: a challenge for geosciences and civil engineering' (Germany) and the Romanian Group for Strong Vrancea Earthquakes (RGVE) in a multidisciplinary attempt towards earthquake mitigation. The cooperation between the Geophysical and Geological Institutes of Karlsruhe University with both NIEP and the Faculty of Geology of Bucharest University focussed in particular on the deep geology of the Vrancea area and surrounding provinces with emphasis on seismicity studies and crust and upper-mantle investigations. Two long-range seismic wide-angle profiles from Bacau to the Danube south of Bucharest recorded in 1999 and from Transylvania to the Dobrogea recorded in 2001, both crossing each other in the Vrancea area, will provide a detailed 3-dimensional crustal structure image of Vrancea and adjacent Carpathians and their surrounding basins, while a temporary array of 120 mobile stations distributed throughout southeastern Romania recorded local and far-distant earthquakes for about 6 months in 1999 which will allow to derive a 3-dimensional tomographic image of the underlying uppermost mantle to depths of about 300 km.

    2003-08-01

    Among the analytical techniques (mass spectrometry, laser Raman spectroscopy, gas chromatography, use of ionisation chambers) employed at the Tritium Laboratory Karlsruhe (TLK), gas chromatography plays a prominent role. The main reasons for that are the simplicity of the gas chromatographic separation process, the small space required for the equipment, the low investment costs in comparison to other methods, the robustness of the equipment, the simple and straightforward analysis and the fact that all gas species of interest (with the exception of water) can easily be detected by gas chromatographic means. The conventional gas chromatographs GC1 and GC2 used in the Tritium Measurement Techniques (TMT) System of the TLK and the gas chromatograph GC3 of the experiment CAPER are presented in detail, by discussing their flow diagrams, their major components, the chromatograms measured by means of various detectors, shortcomings and possible improvements. One of the main disadvantages of the conventional gas chromatography is the long retention times required for the analysis of hydrogen gas mixtures. To overcome this disadvantage, micro gas chromatography for hydrogen analysis was developed. Reduction of the retention times by one order of magnitude was achieved. (orig.)

    International Nuclear Information System (INIS)

    1990-01-01

    Transient-tested high burn-up fuel samples were investigated by electron microscopy to study the effect of strain on fission product distribution, and the concentration of (U,Pu)O 2 agglomerates in irradiated MOX fuel was examined by electron microprobe analysis. Conclusions on maximum temperatures to which the core of the Three Mile Island reactor was exposed could be drawn from an examination of TMI fuel debris. Equipment to measure thermophysical fuel properties for reactor safety studies was further developed. An improved version (slice version) of the TRANSURANUS fuel pin code was tested and released for external use. Safety Aspects of Fuel Operation and Handling were dealt with by improving preparation methods of (U,Pu)N. Release and resuspension of radioactive dust particles in fires was studied. The principal objective of the Actinide Determination and Recycling activity was the reduction of long-term hazards of alpha-bearing nuclear waste. The long-term storage behaviour of UO 2 and MOX spent fuel samples as well as of vitrified waste forms was further investigated by studying the effect of leaching. The electronic structure of the transuranium elements is the central objective of basic Actinide Research. A large number of ternary alloys containing Np or Pu and Si or Ge, together with a transition metal was prepared for basic experimental studies. New high-pressure phases were discovered in PuSe, UPS, ThO 2 , and PuO 2 . Analytical techniques were evaluated and automated for safeguards. A multiwavelength pyrometer was adapted for industrial use. Major contracts with Third Parties were dealing with the development of minor actinide alloys, and the post-irradiation examination of high burn-up UO 2 and MOX fuel from LWR power stations

  5. The Karlsruhe 4π barium fluoride detector

    A new experimental approach has been implemented for accurate measurements of neutron capture cross sections in the energy range from 5 to 200 keV. The Karlsruhe 4π Barium Fluoride Detector consists of 42 crystals shaped as hexagonal and pentagonal truncated pyramids forming a spherical shell with 10 cm inner radius and 15 cm thickness. All crystals are supplied with reflector and photomultiplier, thus representing independent gamma-ray detectors. Each detector module covers the same solid angle with respect to a gamma-ray source located in the centre. The energy resolution of the 4π detector is 14% at 662 keV and 7% at 2.5 MeV gamma-ray energy, the overall time reslution is 500 ps and the peak efficiency 90% at 1 MeV. The detector allows to register capture cascades with 95% probability above a threshold energy of 2.5 MeV in the sum energy spectrum. Neutrons are produced via the 7 Li(p,n) 7 Be reaction using the pulsed proton beam of a Van de Graaff accelerator. The neutron spectrum can be taylored according to the experimental requirements in an energy range from 5 to 200 keV by choosing appropriate proton energies. A collimated neutron beam is passing through the detector and hits the sample in the centre. The energy of captured neutrons is determined via time of flight, the primary flight path being 77 cm. The combination of short primary flight path, a 10 cm inner radius of the spherical BaF 2 shell, and the low capture cross section of barium allows to discriminate background due to capture of sample scattered neutrons in the scintillator by time of flight, leaving part of the neutron energy range completely undisturbed.

    Hoehlein, G.; Huppert, K.L.; Winter, M.

    1977-01-01

    The Wiederaufarbeitungsanlage Karlsruhe (WAK) serves as a demonstration plant for the processing of highly-irradiated uranous oxide. The high active waste concentrates find interim storage at the WAK until they are solidified at a later stage. In contrast to this, the slightly- and the medium-active liquid wastes are transported to the decontamination facility of the Nuclear Research Centre Karlsruhe, where they are immediately processed. These liquid wastes contain about 1 per thousand of the activity inventary of the fuel elements processed. Monitoring of the radioactive waste water of the WAK is carried out by the Nuclear Research Centre's department radiation protection and safety. (orig.) [de

    Radioactivity has been known for more than a hundred years. Nuclear data compilations through nuclide charts began in the 1920s with the work of Soddy, and were later rationalized in the Karlsruher Nuklidkarte. For 50 years, it has depicted the status of our nuclear knowledge in an easy reading form. It was born as an educational and scientific tool that gives access to the basic bricks that the nuclear Physics community needs to build the physics knowledge at the femtometer (10 -15 m) level. Nuclide data is a bridge between research and development. On the one hand, the nucleus can be regarded as a vast laboratory with, the possibility to test from fundamental concepts of the Standard Model to the genesis of the elements in the Universe. On the other hand, this data is also leading to applications in many areas of everyday life such as health care or environmental monitoring. (author)

    2001-01-01

    The case of Forschungszentrum Karlsruhe is presented which had to transform from a centre devoted to nuclear power R and D to one in which this activity is allocated only 20% of the resources. A large number of operating nuclear power reactors coupled with the Government decision to phase out nuclear power is causing serious concerns regarding the availability of human resources for meeting the long term needs of nuclear facilities. The Energy Division of the research centre currently focuses mainly on safety research and on nuclear fusion. Another Division of the centre has nuclear facility decommissioning as one of the programmes. Independent research in areas of essential need for nuclear facilities must be carried out to maintain know how. (author)

    Doctors today already frequently rely on positron emission tomography - PET for short - in cancer diagnostics. However, in order to use this method for other diseases, too, they need suitable tracer substances containing radioactive fluorine-18 - a challenge for Tobias Ritter and his team at the Max Planck Institut fuer Kohlenforschung in Muelheim an der Ruhr. The chemists are searching for ways to label diverse molecules with fluorine-18 and thus expand the range of possibilities for medical specialists.

    The Current Lead Test facility Karlsruhe (CuLTKa) is under construction at the Karlsruhe Institute of Technology (KIT) to perform acceptance tests of high temperature superconductor (HTS) current leads (CL). CuLTKa is in progress and present planning expects the completion in 2013. The data acquisition system is based on a modular design with electronic measurement and monitoring equipment covering a test voltage of 50 kV DC against ground. It provides plug-in units which enable temperature and voltage measurement at high voltage potential and in addition quench detection units which detect a loss of superconductivity reliably and quickly to avoid damage of the superconducting device under test. Prototype units for quench detection, temperature and voltage measurement have been successfully tested. Six temperature measurement units are already in use in the KIT test facility TOSKA and operated reliably during the acceptance tests of the HTS current leads for Wendelstein 7-X (W7-X) in 2011/2012. CuLTKa will be used first for 26 current leads which will be built in KIT for the fusion experiment JT-60SA. The present paper gives an overview of the design of the electronic measurement and quench detection equipment

  14. Neuropathological research at the "Deutsche Forschungsanstalt fuer Psychiatrie" (German Institute for Psychiatric Research) in Munich (Kaiser-Wilhelm-Institute). Scientific utilization of children's organs from the "Kinderfachabteilungen" (Children's Special Departments) at Bavarian State Hospitals.

    Science.gov (United States)

    Steger, Florian

    2006-09-01

    During National Socialism, the politically motivated interest in psychiatric genetic research lead to the founding of research departments specialized in pathological-anatomical brain research, the two Kaiser Wilhelm-Institutes (KWI) in Berlin and Munich. The latter was indirectly provided with brain material by Bavarian State Hospitals, to three of which "Kinderfachabteilungen" (Special Pediatric Units) were affiliated. As children became victims of the systematically conducted child "euthanasia" in these Special Pediatric Units, this paper will address the question whether and to which extent the organs from victims of child "euthanasia" were used for (neuro-) pathological research at the KWI in Munich. By means of case studies and medical histories (with focus on the situation in Kaufbeuren-Irsee), I will argue that pediatric departments on a regular base delivered slide preparations, that the child "euthanasia" conduced in these departments systematically contributed to neuropathological research and that slide preparations from victims of child "euthanasia" were used in scientific publications after 1945.

    The Karlsruhe Research Center is a national research establishment placed under the responsibility of the Federal Republic of Germany and the Federal Land of Baden-Wuerttemberg, and as a member of the Hermann von Helmholtz-Gemeinschaft Deutscher Forschungszentren belongs to the most important and independent research centers in Germany working in the fields of the natural sciences and engineering sciences. The center's research and development activities are defined in coordination with the policy and programmes of the two responsible Federal and Land Governments and span the range from pre-industrial research through to product and process development, research of a provident nature, and fundamental scientific research work, with almost all R and D activities of the center relating in one way or other to technology and the environment. The research programme of the center today covers subjects and aspects relating to the environment, energy, key technologies, and fundamental research, whereas at the time the center was founded, nuclear science and engineering was the dominating field of activities. The current spectrum of activities reflects the evolution in the past and is characterized by a great complexity of problems involved, which requires cross-disciplinary cooperation, and foresight in the definition of tasks and time horizons.

    Baehr, W; Hempelmann, W; Krause, H

    1976-06-01

    In 1971 a large incineration plant started operation in the Nuclear Research Center Karlsruhe. This plant is serving for routine incineration of up to 100 kg of combustible radioactive solids or 40 l of contaminated organic liquids and oils per hour. A dry off-gas cleaning system has been developed for this installation in which the fumes are cleaned by ceramic filter candles. After passing the filtering system and cooling, the off-gas is discharged directly through a stack. The activity concentration in the off-gas is measured by a continuous monitoring system. The ashes arising from the incineration are mixed with cement grout and filled into 200 l-drums. By this way approximately one drum of fixed ashes results from 100 drums of combustible wastes. During the first four years of operation, more than 4,000 m/sup 3/ of combustible solids and about 60 m/sup 3/ organic solvents have been incinerated in the plant. The operating experiences are presented.

    Caldarola, L.; Wickenhaeuser, A.

    1977-01-01

    A very fast analytical computer program for fault tree evaluation has already been developed at the German nuclear research center of Karlsruhe. This program can evaluate coherent systems assuming binary component states. Four different classes of components can be handled by the program: (1) unrepairable components, (2) repairable components with revealed faults, (3) repairable components with faults remaining unrevealed until next demand occurs and (4) repairable components with faults which are detected upon inspection. The program can perform also time dependent calculations. In particular the program can analyse systems characterized by two phases, one following the other in time (two time axis). A new computer program is also being developed. This computer program will be capable to analyse noncoherent systems with multistate components. The mathematical theory supporting the new program is described in the paper. In particular the algorithm for the identification of the prime implicants and the theory for the calculation of the occurrence probability and of the first occurrence probability of the TOP event are discussed

    The Nuclear Research Center Karlsruhe (KfK) is funded to 90% by the Federal Republic of Germany and to 10% by the State of Baden-Wuerttemberg. Since its foundation in 1956 the main objective of the Center is research and development (R and D) in the aera of the nuclear technology and about 2/3 of the research capacity is now devoted to this field. Since 1960 a major activity of KfK is R and D work for the design of fast breeder reactors, including material research, physics, and safety investigations; a prototype of 300 MWe is under construction now in the lower Rhine Valley. For enrichment of 235 U fissile material KfK developed the separation nozzle process; its technical application is realized within an international contract between the Federal Republic of Germany and Brazil. Within the frame of the European Programme on fusion technology KfK develops and tests superconducting magnets for toroidal fusion systems; a smaller activity deals with research on inertial confinement fusion. A broad research programme is carried through for safety investigations of nuclear installations, especially for PWRs; this activity is supplemented by research and development in the field of nuclear materials' safeguards. Development of fast reactors has to initiate research for the reprocessing of spent fuel and waste disposal. In the pilot plant WAK spent fuel from LKWs is reprocessed; research especially tries e.g. to improve the PUREX-process by electrochemical means, vitrification of high active waste is another main activity. First studies are being performed now to clarify the necessary development for reprocessing fast reactor fuel. About 1/3 of the research capacity of KfK deals with fundamental research in nuclear physics, solid state physics, biology and studies on the impact of technology on environment. Promising new technologies as e.g. the replacement of gasoline by hydrogen cells as vehicle propulsion are investigated. (orig.)

    The Tritium Laboratory Karlsruhe (TLK) accomplished commissioning; tritium involving activities will start this year. The laboratory is destined mainly to investigating processing of fusion reactor fuel and to developing analytic devices for determination of tritium and tritiated species in view of control and accountancy requirements. The area for experimental work in the laboratory is about 800 m{sup 2}. The tritium infrastructure including systems for tritium storage, transfer within the laboratory and processing by cleanup and isotope separation methods has been installed on an additional 400 m{sup 2} area. All tritium processing systems (=primary systems), either of the tritium infrastructure or of the experiments, are enclosed in secondary containments which consist of gloveboxes, each of them connected to the central depressurization system, a part integrated in the central detritiation system. The atmosphere of each glovebox is cleaned in a closed cycle by local detritiation units controlled by two tritium monitors. Additionally, the TLK is equipped with a central detritiation system in which all gases discharged from the primary systems and the secondary systems are processed. All detritiation units consist of a catalyst for oxidizing gaseous tritium or tritiated hydrocarbons to water, a heat exchanger for cooling the catalyst reactor exhaust gas to room temperature, and a molecular sieve bed for adsorbing the water. Experiments with tracer amounts of tritium have shown that decontamination factors >3000 can be achieved with the TLK detritiation units. The central detritiation system was carefully tested and adjusted under normal and abnormal operation conditions. Test results and the behavior of the tritium barrier preventing tritiated exhaust gases from escaping into the atmosphere will be reported.

    The LACOMERA project at the Forschungszentrum Karlsruhe, Germany, is a 4 year action within the 5th Framework Programme of the EU which started in September 2002. Overall objective of the project is to offer research institutions from the EU member countries and associated states access to four large-scale experimental facilities QUENCH, LIVE, DISCO, and COMET. These facilities can be used to investigate core melt scenarios from the beginning of core degradation to melt formation and relocation in the vessel, possible melt dispersion to the reactor cavity, and finally corium concrete interaction and corium coolability in the reactor cavity. The paper summarises the main results obtained in the following experiments performed up to now. QUENCH-L1: Impact of air ingression on core degradation. The test provides unique data for the investigation of air ingress phenomenology in conditions as representative of a spent fuel pool accident as possible; QUENCH-L2: Boil-off of a flooded bundle. The test is of a generic interest for all reactor types, provided a link between the severe accident and design basis areas, and would deliver oxidation and thermal hydraulic data at high temperatures. DISCO-L1: Thermal hydraulic behaviour of the corium melt dispersion neglecting the chemical effects such as hydrogen generation and combustion. COMET-L1: Long-term 2D concrete ablation in a siliceous concrete cavity at intermediate decay heat power level with a top flooding phase after a phase of dry concrete erosion. COMET-L2: Investigation of long-term melt-concrete interaction of metallic corium in a cylindrical siliceous concrete cavity under dry conditions with decay heat simulation of intermediate power during the first test phase, and subsequently at reduced power during the second test phase.

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

    To the argument that the long half-life values of the most important products of fission represent an unacceptable burden for coming generations, the author retorts that this is an emotion-directed pseudo-argument. Anyone who ventures into deep geological strata, such as the final storage area Konrad, should also count in terms of geological periods. From this point of view, a million years - however difficult to imagine for the average human being - is not a very long time. Toxic chemical waste is accepted by society, even if the toxicity should remain for all time. The article is an extract from a lecture given by the author to the Franco-German Society for Science and Technology. (orig.) [German] Dem Argument, die langen Halbwertszeiten der wichtigsten Spaltprodukte beinhalte eine nicht zu verantwortende Belastung fuer die nachfolgenden Generationen, haelt Autor Tillessen entgegen, dass dies ein auf Emotionen abzielendes Scheinargument sei. Wer sich, wie zum Beispiel beim Endlager Konrad, in tiefe geologische Schichten begebe, duerfe auch in geologischen Zeitraeumen rechnen. Und da sei eine Million Jahre, so wenig vorstellbar das auch fuer den Durchschnitts-Menschen sei, eben keine allzulange Zeit. Chemische Giftabfaelle wuerden von der Gesellschaft akzeptiert, obwohl ihre Toxitaet ewig waehre. Der Beitrag des Autors ist ein Auszug aus einer Rede, die er vor der Deutsch-Franzoesischen Gesellschaft fuer Wissenschaft und Technik gehalten hat. Aus diesem Anlass hatte Tillessen vorgeschlagen, ein von einer Stiftung getragenes deutsch-franzoesisches Institut zu gruenden, dessen Aufgabe es sein soll, mit mehr Rationalitaet die von teutonischer Romantik dominierte Technikdiskussion zu versachlichen.

    The emphasis of the conference was on methods of measurement that show spatial distributions of phase fractions and velocity, particle sizes and bubbles of the disperse phase. Among the methods described were 3D X-ray tomography, grid sensor measurement of velocity profiles, and simultaneous measurement of bubble sizes and gas and liquid flow rates using an optical particle tracking method. Also presented were interesting developments in the field of local probes, e.g. an electrodiffusion probe. Another new development was the attempt to use optical tomography for investigations of two-phase flows. [German] Am 14. Oktober 1999 wurde in Rossendorf die dritte Veranstaltung in einer Serie von Workshops ueber Messtechnik fuer stationaere und transiente Mehrphasenstroemungen durchgefuehrt.

Besonders hervorzuheben sind die beiden Hauptvortraege, die von Herrn Professor Hetsroni aus Haifa und Herrn Dr. Sengpiel aus Karlsruhe gehalten wurden. Ihnen und allen anderen Vortragenden moechten wir herzlich fuer ihren Beitrag zum Gelingen des Workshops danken. Erneut lag ein wichtiger Schwerpunkt auf Messverfahren, die raeumliche Verteilungen von Phasenanteilen und Geschwindigkeiten sowie die Groesse von Partikeln bzw. Blasen der dispersen Phase zugaenglich machen. So wurde ueber einen dreidimensional arbeitenden Roentgentomographen, ein Verfahren zur Messung von Geschwindigkeitsprofilen mit Gittersensoren und eine Methode zur simultanen Messung von Blasengroessen sowie Feldern von Gas- und Fluessigkeitsgeschwindigkeit mit einer optischen Partikelverfolgungstechnik vorgetragen. Daneben wurden interessante Entwicklungen auf dem Gebiet der lokalen Sonden vorgestellt, wie z.B. eine Elektrodiffusionssonde. Neue messtechnische Ansaetze waren ebenfalls vertreten; hervorzuheben ist der Versuch, die Methode der optischen Tomographie fuer die Untersuchung von Zweiphasenstroemungen nutzbar zu machen.

    Full text of publication follows. The work on minor actinide (MA) partitioning carried out at Karlsruhe and Juelich is integrated in the EC FP6 programme, EUROPART. Studies include the DIAMEX process (co-extraction of MA and lanthanides from PUREX raffinate) and the SANEX process (separation of MA from lanthanides). Aspects ranging from developing and improving highly selective and efficient extraction reagents, to fundamental structural studies, to process development and testing are covered. SANEX is a challenge in separation chemistry because of the chemical similarity of trivalent actinides and lanthanides. The extracting agents 2,6-di(5,6-di-propyl-1,2,4-triazine-3-yl)pyridine (n-Pr-BTP), developed at Karlsruhe, and the synergetic mixture of di(chloro-phenyl)di-thio-phosphinic acid (R2PSSH) with tri-n-octyl-phosphine oxide (TOPO), developed at Juelich, are considered a breakthrough because of their high separation efficiency in acidic systems. Separation factors for americium over lanthanides of more than 30 (R2PSSH+TOPO) and 130 (n-Pr-BTP) are achieved. To gain understanding of these selectivities, comparative investigations on the structures of curium and europium complexed with these SANEX ligands were performed at Karlsruhe. Extended X-ray absorption fine structure (EXAFS) analysis revealed distinct structural differences between curium and europium complexed with R2PSSH + TOPO, though no such differences were found for n-Pr-BTP. These investigations were therefore complemented by time-resolved laser fluorescence spectroscopic investigations (TRLFS), showing complex stabilities and speciation to differ between n-Pr-BTP complexes of curium and europium. Kinetics of mass transfer was studied for both R2PSSH+TOPO and n-Pr-BTP systems. For the R2PSSH + TOPO system, diffusion was identified to control extraction rates. For the n-Pr-BTP system, a slow chemical reaction was identified as the rate-controlling process. These results were implemented into computer

    The Karlsruhe Monte Carlo Code KAMCCO is a forward neutron transport code with an eigenfunction and a fixed source option, including time-dependence. A continuous energy model is combined with a detailed representation of neutron cross sections, based on linear interpolation, Breit-Wigner resonances and probability tables. All input is processed into densely packed, dynamically addressed parameter fields and networks of pointers (addresses). Estimation routines are decoupled from random walk and analyze a storage region with sample records. This technique leads to fast execution with moderate storage requirements and without any I/O-operations except in the input and output stages. 7 references. (U.S.)

All necessary process control data of the first extraction cycle is collected via a data collection system and is displayed in suitable ways on a screen for the operator in charge of the unit. To aid verification of displayed data, various measurements are associated to each other using balance type process modeling. Thus, deviation of flowsheet conditions and malfunctioning of measuring equipment are easily detected. (orig.) [de

    The application of modern simulation tools offering additional support during the vehicle development process is accepted to a large extent by most car manufacturers. Just like new model-based control strategies, these simulation investigations require very accurate - and thus very complex - models of vehicle dynamics, which can be processed in real time. As an example of such a vehicle model, this article describes a real-time vehicle simulation model which was developed at the Institute of Automatic Control at Darmstadt University of Technology, in co-operation with the ITDC of the Adam OPEL AG. By applying modern adaptation techniques, this vehicle model is able to calculate onboard the important variables describing the actual driving state even if the environmental conditions change.

    After the operation of the KNK plant with a thermal core (KNK I), the installation of a fast core (KNK II) had been realized. The planning of the core and the necessary reconstruction work was done by INTERATOM. Owner and customer was the Nuclear Research Center Karlsruhe (KfK), while the operating company was the Kernkraftwerk-Betriebsgesellschaft mbH (KBG) Karlsruhe. The main goals of the KNK II project and its special experimental test program were to gather experience for the construction, the licensing and operation of future larger plants, to develop and to test fuel and absorber assemblies and to further develop the sodium technology and the associated components. The present safety report consists of three parts. Part 1 contains the description of the nuclear plant. Hereby, the reactor and its components, the handling facilities, the instrumentation with the plant protection, the design of the plant including the reactor core and the nominal operation processes are described. Part 2 contains the safety related investigation and measures. This concerns the reactivity accidents, local cooling perturbations, radiological consequences with the surveillance measures and the justification of the choice of structural materials. Part three finally is the appendix with the figures, showing the different buildings, the reactor and its components, the heat transfer systems and the different auxiliary facilities [de

    Evaluation of the data from the personnel dosimetry of the staff monitored from 1969 until 1981 at the Karlsruhe Nuclear Research Center (Kernforschungszentrum Karlsruhe GmbH) gives a total external dose of 6,335 rem including natural radiaiton background. The occupational exposure of the radiation workers within this period comes to 3,076 rem, which gives an average annual external occupational exposure of 0.14 rem. In 1,832 cases an annual dose between 0.5 and 1.5 rem per year and in 353 cases a dose of more than 1.5 rem per year have been measured. The highest value, measured in 1972, amounted to 6.8 rem. During the period from 1969 until 1981 more than 34,000 incorporation measurements were performed with the whole body counter and the lung counter, 1,963 cases with positive findings. In 96% of the cases the values of incorporated activity were inferior to 1% - in 70% even inferior to 0.1% - of the maximum permissible body burden values of ICRP 2. Only 5 cases exceeded these values. (orig.) [de

    At the Tritium Laboratory Karlsruhe (TLK) laser Raman spectroscopy, gas chromatography, mass spectroscopy, calorimetry and ionisation chambers are used to determine the composition of tritium gas mixtures. For the first time a laser Raman experiment was assembled with an actively controlled resonator which yields a 50 times higher Raman signal and with all components (laser, optics, Raman cell and spectrometer) installed inside a glove box. Three gas chromatographs, each with up to six detectors, can determine the gases and their tritiated fractions expected in fusion devices down to the sub-ppm range. Tritium in solids, liquids and gases is determined by means of three calorimeters with a dynamic ranges of up to five orders of magnitude and a lower detection limit of 1 GBq. Since any of these techniques has its shortcomings the best analytical approach is to analyse a sample by more than one method

    1982-01-01

    Plutonium and 129 I are emitted from the Karlsruhe Reprocessing Plant (WAK) together with exhaust air and liquid effluents. Plutonium dispersion in the environment was used to calculate the dispersion factors, to determine the rates of deposition on grass and of the total deposition rates, to measure the distribution at depth of plutonium in the soil and to evaluate the contamination of plants and animals in the environment of the Karlsruhe Reprocessing Plant. The plutonium emissions with the liquid effluents were studied to deepen understanding of the process of sedimentation in a river system. Sediments, water samples, aerosols and living organisms from the Altrhein were examined. Factors of transfer to various organisms living in the Altrhein were measured. Most of the 129 I release from WAK goes via the exhaust air: this even applies after installation of an iodine filter into the exhaust air stack. The 129 I contamination of the environmental air, the soil, thyroids and milk was measured. Regarding the milk/air concentration ratio, a mean value of 210 was determined with a scattering range of 50 to 1480. Soil contamination was studied very thoroughly. Iodine-129 is transported into lower soil layers at a very slow rate only, if at all. The contamination of the soil with 129 I remained largely constant during the three years of investigations. The low rates of deposition of 0.02 to 0.05 cm/s indicate that 129 I is released to the environmental air again from plants undergoing the process of rotting. (author)

    The planned ITER plant needs plasma heating powers of approx. 70-150 MW. Work performed at the Karlsruhe Research Center under this heading mainly comprises the development of microwave oscillators (gyrotrons) and their use for an electron cyclotron resonance heating system and for non-inductive plasma current operation. The plasma, which is approx. 100 million C hot, is confined in a 'magnetic cage' so as to avoid any contact with the wall structures of the vacuum vessel. Building up a magnetic field of this magnitude requires field strengths of at least 2-5 tesla in the plasma; field strengths of 11-13 tesla at the magnet coils are required for future fusion plants, such as ITER. Consequently, the development of the required future superconducting magnet coils enjoys high priority. The blanket, i.e. the enclosure around the combustion chamber of a fusion reactor, plays a major role in the design of a future fusion power plant. Blanket concepts meeting technical requirements are being developed and studied. A blanket must meet three requirements: It must convert the neutron energy into heat, breed the tritium fuel by nuclear reactions, and shield the magnets from neutron and gamma radiations. The fuel cycle of fusion reactors is determined by the gaseous phase of the two hydrogen isotopes, deuterium and tritium. In general, hydrogen handling technologies have been developed to a high level, but can be transferred to the handling of deuterium and radioactive tritium only to a very limited extent. Consequently, the necessary development work is carried out. The state of the plasma, also with respect to its purity, is a factor of special importance, as impurities will cause the plasma to dissolve and thus the fusion reaction to break down. Primary vacuum pumps, another area of activity of the Karlsruhe Research Center, first must evacuate the reactor vessel and then, during operation, maintain the necessary atmosphere. (orig.) [de

    A central question of today's political debates is: Which means are there for ensuring a long-term and sustainable energy supply? Here, strategies for covering tomorrow's energy supply assign renewable energies a decisive role. In face of constantly rising prices for fossil fuels like carbon, oil and gas or the still open question concerning the removal of atomic waste, these discussions are eminently urgent. In order to confront climatic change, renewable energies are needed, so that also in the future a longterm and sustainable energy supply is secured. Sustainable energy supply is the context for the project Solarsupport, which has been supported by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (FKZ 0327613). The project has been coordinated by the Institute for Environmental Questions (''Unabhaengige Institut fuer Umweltfragen e.V.'' - UFU) and conducted in cooperation with the Institute for Future Studies and Technology Assessment (''Institut fuer Zukunfststudien und Technologiebewertung gGmbH'' - IZT) and the German Society for Solar Energy, Regional Association Berlin-Brandenburg (Deutsche Gesellschaft fuer Sonnenenergie Regionalverband Berlin-Brandenburg e.V. - DGS). Particularly, the project is concerned with the pedagogical use of solar energy at school. Despite the relatively high number of solar plants at schools, only a few use their plants for pedagogical means. The project Solarsupport surveyed schools with solar plants. As the main reason for the insufficient pedagogical use of solar plants the interviewed teachers named the la ck of a pedagogical concept and their colleagues' disinterest, two factors which are able to reinforce one another. Moreover, it became clear that because of their insufficient technical equipment (no displays, no means for evaluating the plants' output, no connection with the school computers and internet) a high number of the

    The safe decommissioning of nuclear installations is technically feasible, but is also still a challenge for science, technology and industry. The expertise and know how for decommissioning must be ensured because it will be needed for further decades. Already in 2008 the Karlsruhe Institute of Technology (KIT) had identified this challenge that later emerged through the closure of nuclear power plants in Germany. The KIT opened the professorship Technology and Management of the Decommissioning of Nuclear Installations. In 2014, this section was extended through the dismantling of conventional installations.

    After a Conceptual Design Activity (CDA) study on an International Fusion Material Irradiation Facility (IFMIF) has been launched under the auspices of the IEA, working groups and relevant tasks have been defined and agreed in an IEA-workshop that was held September 26-29 1994 at Karlsruhe. For the Test Cell System 11 tasks were identified which can be grouped into the three major fields neutronics, test matrix/users and test cell engineering. In order to discuss recently achieved results and to coordinate necessary activities for an effective design integration, a technical workshop on the Test Cell System was initiated. This workshop was organized on July 3-6 1995 by the Institute for Materials Research I at the Forschungszentrum Karlsruhe and attended by 20 specialists working in the fields neutronics, fusion materials R and D and test cell engineering in the European Union, Japan, and the United States of America. The presentations and discussions during this workshop have shown together with the elaborated lists of action items, that has been achieved in all three fields, and that from the future IFMIF experimental program for a number of materials a database covering widerspread loading conditions up to DEMO-reactor relevant end-of-life damage levels can be expected.

    This Working Material (including the attached CD-ROM) documents progress made in the IAEA's initiative to preserve knowledge in the fast reactor domain. The brochure describes briefly the context of the initiative and gives an introduction to the contents of the CD-ROM. In 2003/2004 a first focus of activity was concentrated on the preservation of knowledge related to the KNK-II experimental fast reactor in Karlsruhe, Germany. The urgency of this project was given by the impending physical destruction of the installation, including the office buildings. Important KNK-II documentation was brought to safety and preserved just in time. The CD-ROM contains the full texts of 264 technical and scientific documents describing research, development and operating experience gained with the KNK-II installation over a period of time from 1965 to 2002, extending through initial investigations, 17 years of rich operating experience, and final shutdown and decommissioning. The index to the documents on the CD-ROM is printed at the end of this booklet in chronological order and is accessible on the CD by subject index and chronological index. The CD-ROM contains in its root directory also the document 'fr c lassification.pdf' which describes the classification system used for the present collection of documents on the fast reactor KNK-II

    1976-06-01

    Under an IAEA sponsored measurement program the tritium level is investigated in the immediate and more distant environment of the Karlsruhe Nuclear Research Center. The tritium concentration in precipitations, surface, ground and drinking water is measured within a long-term program. In addition, relationships existing between the tritium concentration of plants and the concentrations of ground water, precipitation, soil and air humidities are investigated at three points in special series of measurement. A summary report is presented on recent measured results. According to these results, the annual mean values for precipitations and surface water tend to rise. In 1975 the annual mean values amounted to 0.89 nCi/l of tritium concentration in precipitations in the more distant environment of the Nuclear Research Center and to 0.68 nCi/l in the Rhine river. In plants tritium concentrations were observed which correspond to that measured in the humidity of the air. The radiation exposure of people living in large towns is calculated to be about 50 μrem/a in the region monitored, due to the presence of tritium in the drinking water. A little group of the population takes up as much as 110 μrem/a. (orig.) [de

  1. Research on transmutation and accelerator-driven systems at the Forschungszentrum Karlsruhe

    International Nuclear Information System (INIS)

    Knebel, J.U.; Heusener, G.

    2000-01-01

    Transmutation is considered a promising technology worldwide for significantly reducing the amount and, thereby, the long-term radiotoxicity of high active waste (HAW) produced by the operation of nuclear power plants such as light water reactors (LWR). The maximum reduction of radiotoxicity could be by a factor of about 100. Transmutation is thus an alternative to the direct deposition of large volumes of highly radioactive waste. Transmutation presents the possibility of closing the fuel cycle including the minor actinides. Plutonium, minor actinides and long-lived fission products can be transmuted in a so called Accelerator Driven Sub-critical System (ADS), which consists of an accelerator, a target module and a subcritical blanket. This paper describes the work performed at Forschungszentrum Karlsruhe which is critically evaluating an ADS mainly with respect to its potential for transmuting minor actinides, to its feasibility and to safety aspects. The work is being done in the area of core design, neutronics, safety, system analyses, materials and corrosion. (orig.) [de

  2. In-situ testing of HEPA filters in the nuclear Karlsruhe filter system

    International Nuclear Information System (INIS)

    Ohlmeyer, M.; Stotz, W.

    1977-01-01

    Nuclear plant operators and filter manufacturers are endeavouring to improve environmental protection by intensifying process control and/or improving filter quality. In-situ testing is an important element in these efforts since it represents a direct means of checking the success or otherwise of a particular development. The arrangements for in-situ testing should satisfy the following minimum requirements: the staff should not be exposed to risk during the test; the test method should be objective and reproducible as well as being as sensitive as possible; the test method should permit detection of individual leaks in the filter system so that they can be remedied as efficiently as possible; the test equipment should not necessitate modifications to the extract systems or plant construction; the test should be simple and capable of being carried out with a minimum of effort and equipment. GfK has developed the 'Nuclear-Karlsruhe' filter housing in accordance with these principles. This housing permits in-situ testing similar to the DIN 24184 visual oil-fog test or the DOP test. External visual checks on the general condition of the filter is also possible. A safe system of filter changing with a specially designed plastic bag attachment at an accessible height considerably increases the degree of protection of operating personnel

    In 1971 a large incineration plant started operation in the Nuclear Research Center Karlsruhe. This plant is serving for routine incineration of up to 100 kg of combustible radioactive solids or 40 l of contaminated organic liquids and oils per hour. A dry off-gas cleaning system has been developed for this installation in which the flue gases are cleaned by ceramic filter candles. After passing the filtering system and cooling the off-gas is discharged directly through a stack. The activity concentration in the off-gas is measured by a continuous monitoring system. The ashes arising from the incineration are mixed with cement grout and filled into 200 ldrums. By this way approximately one drum of fixed ashes results from 100 drums of combustible wastes. During the first four years of operation, more than 4,000 m 3 of combustible solids and about 60 m 3 organic solvents have been incinerated in the plant. The operating experiences are presented.

    In various sectors of integration policy, we have now adopted the pragmatic application of the process of ''intergration by stages'' - not without some success, as the contributions to this publication will show. The experience gained in the process and the practical and theoretical problems that occur as a result for European unity are systematically studied for the first time here on a sound scientific basis. The authors study general problems of a typological, legal and institutional nature and selected areas of politics. The articles on European energy policy and environmental policy are of particular interest and have been analysed separately. (orig./HSCH).

    Highlights: • Operation of a water detritiation facility under optimized conditions for high detritiation performances. • Improvement of operational procedures to process tritiated waste water. • Handling and reduction of tritiated waste water to achieve enriched low volume tritiated water for sufficient storage. • Demonstration of the efficient availability of the TRENTA WDS facility for technical scale operation. -- Abstract: A Water Detritiation System (WDS) is required for any Fusion machine in order to process tritiated waste water, which is accumulated in various subsystems during operation and maintenance. Regarding the European procurement packages for the ITER tritium fuel cycle, the WDS test facility TRENTA applying the Combined Electrolysis Catalytic Exchange (CECE) process was developed, installed and is currently in operation at the Tritium Laboratory Karlsruhe (TLK). Besides the on-going R and D work for the design of ITER WDS, the current status of the TRENTA facility provides the option to utilize the WDS for processing tritiated water. Therefore, in the framework of the EFDA JET Fusion Technology Work Programme 2011, the TLK was able to offer the capability on a representative scale to process tritiated water, which was produced during normal operation at JET. The task should demonstrate the availability of the CECE process to handle and detritiate the water in terms of tritium enrichment and volume reduction. The operational program comprised the processing of purified tritiated water from JET, with a total volume of 180 l and an activity of 74 GBq. The paper will give an introduction to the TRENTA WDS facility and an overview of the operational procedure regarding tritiated water reduction. Data concerning required operation time, decontamination and enrichment performances and different operating procedures will be presented as well. Finally, a preliminary study on a technical implementation of processing the entire stock of JET

    Purpose: In 2 institutions exposure values were evaluated and compared with the 2010 updated diagnostic reference levels (DRL) and possibilities for decreasing the dose assessed. Materials and Methods: Mean exposure values obtained during a 3-month period were calculated for all modalities (X-ray: imaging plate system and digital detector; dual-source 64- and 16- slice spiral CT) as well as examination types were compared to old diagnostic reference levels in addition to DRLs introduced in 2010. Then 10 examinations of all modalities and types were accompanied by a medical physicist and optimized stepwise if necessary. Results: The mean values of X-ray examinations were above DRL. All accompanied examinations were beyond DRL except lateral lumbar spine (LSP) and lateral thoracic X-ray, which were elevated due to statistical outliers from morbidly obese patients or patients with metallic implants. For a-p LSP tube voltage was increased. While image quality was maintained, dose area product (DAP) was reduced by 50% to 123 ±61 cGy.cm{sup 2} for LSP a-p and 30% for lateral LSP to 229 ± 116 cGy.cm{sup 2}. For CT examinations, dose was below DRL. Accompanied examinations of the lumbar spine performed on a 16-slice spiral CT demonstrated a result 68% above DRL with dose length product (DLP) of 840 ± 252 cGy . cm. For optimization, pitch and tube voltage were stepwise increased and DLP reduced below DRL. Conclusion: Systematic analysis of our internal exposure values on the occasion of adaptation of DRL is crucial for prompt detection of exceeded values independently from assessment by the responsible authority and initiation of proper measures for decreasing exposure dose. Hereby active dose management is attained. (orig.)

    The performance of the Karlsruhe synchrotron radiation source which was designed originally for X-ray deep-etch lithography comes close to that of first and second generation synchrotron radiation sources. The range of applications spanned by KSSQ is therefore quite similar to that of those machines. The present report displays a first collection of topics from the fields of surface analysis, solid state and materials research, and biology which could be investigated using KSSQ by interested groups coming from KfK and its surroundings.

    A procedure was developed to measure Pu-241 by liquid scintillation counting. Sample preparation was performed by electroplating of plutonium on stainless steel planchets. To correct the selfabsorption, the linear dependence of counting efficiency in the liquid scintillation counter from the resolution in the alpha spectrometer was used. Pu-238, Pu-239+240 and Pu-241 were measured in the liquid effluents of the Karlsruhe Nuclear Research Center (KfK). The concentrations in monthly mixed samples ranged from 0.07 until 46 nCi Pu-238/m 3 , from 0.13 until 2.1 nCi Pu-239+240/m 3 and from 25 until 190 nCi Pu-241/m 3 . Between 5.4% and 41% of the plutonium content of the KfK waste water are released to the River Old Rhine. The values for the activity ratio Pu-238/Pu-239+240 are between 0.39 and 1.1 and for Pu-241/Pu-239+240 are between 11 and 300. The mean value for Pu-241/Pu-239+240 is 61. The dose exposure of the environmental population of the Karlsruhe Nuclear Research Center caused by released Pu-241 is negligible low. (orig./HP) [de

    The energy transition in the heating sector is not a sure-fire success and it is too slow. This is alarming since the heating / cooling sector is responsible for more than half of the final energy demand. That the ''thermal change'' has accelerated hardly despite many efforts by politics, industry and research in recent years, is the reason for the scientists the FVEE institutes to examine the perspectives of renewable energy and the need to increase efficiency in the heating sector systematically. therefore FVEE-2015 Annual Meeting, is entitled ''Research for the thermal change''. The contributions of this conference proceedings present the latest research results and show ways to implement the heat change technically, economically and politically. They are dedicated to the drivers, but also the barriers of heat change. The authors report on innovative projects to provide buildings with heat from geothermal energy, biomass and solar thermal energy. Several contributions are dedicated to the application of efficient components, such as thermal insulation, thermal storage and heat pumps. [German] Die Energiewende im Waermesektor ist kein Selbstlaeufer und kommt zu langsam voran. Das ist alarmierend, da der Waerme-/Kaeltesektor fuer ueber die Haelfte des Endenergiebedarfs verantwortlich ist.

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

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

  9. Report on the first two IAEA-courses on nuclear power project planning and implementation in Karlsruhe

    International Nuclear Information System (INIS)

    Reuter, H.H.

    1977-01-01

    There is no more doubt about the necessity of utilizing nuclear energy to cover the world energy requirements. A growing number of developing countries find themselves compelled to use nuclear energy in order to meet their rising energy demands and, hence, to improve their conditions of life. On the other hand, the lack of suitable experts having gathered experience is particularly perceptible in these countries. For this reason, IAEA has organized training courses on an international level, which are held in Karlsruhe (Federal Republic of Germany), Saclay (France), and Argonne (USA). Taking into account the situation in the respective developing country, independent courses are being offered on ''Nuclear Power Project Planning and Implementation'' and on ''Construction and Operation Management.'' The first course of this type was held at the Karlsruhe Nuclear Research Center from September 8 until December 17, 1975. It was attended by 35 participants from 20 countries. In cooperation with industry and national as well as international authorities the syllabus proposed by IAEA was translated into a training program including all essential questions on the introduction of nuclear energy in developing countries. The next course will take place from September 6 until November 30, 1976. A detailed analysis is presented of the extent to which the expectations of participants have been fulfilled. The status of nuclear technology and the number of candidates having sufficient knowledge is of particular importance in this context. A very significant aspect consists in teaching not only theoretical knowledge but integrating practical application in such training courses, which is demonstrated by examples

  10. The judgment of the Federal Constitutional Court on the phasing out of nuclear power. Consequences for phasing out of coal use; Das Urteil des Bundesverfassungsgerichts zum Atomausstieg. Konsequenzen fuer den Kohleausstieg

    The first nuclear phase out of 2002 has not been a subject of judicial review. The nuclear regulations at that time were based on negotiations between the then federal government and the operators. In the context of these negotiations, the operators themselves were committed to waive a judicial review. The Federal Constitutional Court now had first the opportunity to clarify the legal requirements for phase-out from a certain form of energy generation by means of the constitutional complaints lodged by the operators against the second nuclear phase-out amendment adopted by the 13th Atomic Energy Act. The nuclear phase-out of 2011 with fixed, staggered turn-off data for the individual nuclear power plants is, as a matter of principle, in accordance with the Karlsruher decision. The judgment of 6 December 2016 also merit relevance, especially with regard to the coal exit. [German] Der erste Atomausstieg von 2002 ist nicht gerichtlich ueberprueft worden. Die seinerzeitigen atomgesetzlichen Regelungen beruhten auf Verhandlungen zwischen der damaligen Bundesregierung und den Betreibern. Im Rahmen dieser Verhandlungen hatten sich die Betreiber ihrerseits verpflichtet, auf eine gerichtliche Ueberpruefung zu verzichten. Durch die von den Betreibern gegen den mit der 13. Atomgesetz-Novelle 2011 beschlossenen zweiten Atomausstieg eingelegten Verfassungsbeschwerden hatte das Bundesverfassungsgericht nunmehr erstmals die Gelegenheit, die rechtlichen Voraussetzungen eines Ausstiegs aus einer bestimmten Form der Energieerzeugung zu klaeren. Der Atomausstieg von 2011 mit fixen, gestaffelten Abschaltdaten fuer die einzelnen Atomkraftwerke ist nach der Karlsruher Entscheidung grundsaetzlich verfassungsgemaess. Dem Urteil vom 6. Dezember 2016 kommt auch und gerade im Hinblick auf den Kohleausstieg Relevanz dazu.

    The calculation method of DIN V 18599 represents a very complex model for the estimation of the energy efficiency of buildings. The method is used for certificates too, thus, the number of users is quite high. This fact and the complexity of the method causes high demands on the related software products. Most of the end user software tools work with the calculation engine ibp18599kernel developed by Fraunhofer-Institut for Building Physics. There is a continuous quality control for both, the kernel and the user interfaces, i.e. the end user software. This paper gives an overview of the process of quality control as well as a documentation of a validation model used within this process, i.e. a complex administration building as a sample. (Abstract Copyright [2009], Wiley Periodicals, Inc.) [German] Mit dem Berechnungsverfahren der DIN V 18599 liegt ein umfassendes Berechnungsmodell fuer die energetische Bewertung von Gebaeuden vor. Der grosse Umfang der Verfahren stellt auch an die softwaretechnischen Umsetzungen fuer die Planungspraxis hohe Anforderungen. Das Fraunhofer-Institut fuer Bauphysik hat hierzu den Rechenkern ibp18599kernel entwickelt, der zwischenzeit-lich von zahlreichen Softwarehaeusern fuer Endanwendungsprogramme zur energetischen Bewertung und Erstellung von Energieausweisen eingesetzt wird. Dieser ''Rechenmotor'' unterliegt einer steten Qualitaetskontrolle zur Sicherstellung der Berechnungsgenauigkeit. Der vorliegende Aufsatz stellt den Prozess der Qualitaetssicherung anhand eines neuen Validierungsbeispiels in Form eines komplexen Verwaltungsgebaeudes vor. Die Fallstudie kann auch zur Validierung anderer Berechnungssysteme, die nicht auf dem Rechenkern basieren, genutzt werden. (Abstract Copyright [2009], Wiley Periodicals, Inc.)

    The in vivo monitoring laboratory (IVM) at Karlsruhe Institute of Technology (KIT), with one whole body counter and three partial-body counters, is an approved lab for individual monitoring according to German regulation. These approved labs are required to prove their competencies by accreditation to ISO/IEC 17025:2005. In 2007 a quality management system (QMS), which was successfully audited and granted accreditation, was set up at the IVM. The system is based on the ISO 9001 certified QMS of the central safety department of the Research Centre Karlsruhe the IVM belonged to at that time. The system itself was set up to be flexible and could be adapted to the recent organisational changes (e.g. founding of KIT and an institute for radiation research) with only minor effort.

    An almost quantitative retention of iodine is required in reprocessing plants. For the iodine removal in the off-gas streams of a reprocessing plant various sorption materials had been tested under realistic conditions in the Karlsruhe reprocessing plant WAK in cooperation with the Karlsruhe research center FZK. The laboratory results achieved with different iodine sorption materials justified long time performance tests in the WAK Plant. Technical iodine filters and sorption materials for measurements of iodine had been tested from 1972 through 1992. This paper gives an overview over the most important results, Extended laboratory, pilot plant, hot cell and plant experiences have been performed concerning the behavior and the distribution of iodine-129 in chemical processing plants. In a conventional reprocessing plant for power reactor fuel, the bulk of iodine-129 and iodine-127 is evolved into the dissolver off-gas. The remainder is dispersed over many aqueous, organic and gaseous process and waste streams of the plant. Iodine filters with silver nitrate impregnated silica were installed in the dissolver off-gas of the Karlsruhe reprocessing plant WAK in 1975 and in two vessel vent systems in 1988. The aim of the Karlsruhe iodine research program was an almost quantitative evolution of the iodine during the dissolution process to remove as much iodine with the solid bed filters as possible. After shut down of the WAK plant in December 1990 the removal efficiency of the iodine filters at low iodine concentrations had been investigated during the following years. 12 refs., 2 figs., 2 tabs

  6. Determination and behaviour of plutonium emitted with liquid effluents and exhaust air into the environment of the Nuclear Research Centre Karlsruhe

    Schuettelkopf, H.; Pimpl, M.

    1986-01-01

    The plutonium concentrations in the surroundings of the Karlsruhe Nuclear Research Centre (KfK) are in the range of variation of the global plutonium contamination caused by fallout of atmospheric nuclear tests. Exclusively in the sediments of the Old River Rhine, which serves as main canal for the liquid effluents, higher plutonium concentrations could be detected. The dose exposure of the population living in the environment of the KfK caused by the measured plutonium concentrations is negligible low. From the Karlsruhe Reprocessing Plant (WAK) and the facilities needed to decontaminate radioactive wastes 0.48 GBq (13 mCi) plutonium alpha activity has been emitted within 11 years of operation until 1982 - 1/3 with the liquid effluents and 2/3 with the exhaust air. Following the pathway with the exhaust air, plutonium concentrations in the environment of the Karlsruhe Reprocessing Plant were measured in groundlevel air, in soil, in plants, in food and in animal tissues. Radioecological parameters like dispersion factors, deposition velocities, migration velocities in soil and transfer soil-to-plant were investigated. Following the pathway with the liquid effluents, plutonium concentrations were measured in surface waters, sediments, water plants, plankton and animals. Dilution and sedimentation behaviour were studied as well as the transfer water-to-plant and water-to-animals. (orig.) [de

    Several sections of HAWC glass rods remaining at the end of glass pouring at the Karlsruhe Vitrification Plant (VEK) were retained during vitrification operation in 2009-2010 and transferred to the KIT-INE shielded box line for later glass product characterization. A mm sized fragment with a contact dose rate of ∼590 μSv/h was selected for pilot XAS/XRF investigations at the INE-Beamline for actinide science at the ANKA synchrotron radiation source. The experiment was aimed at elucidating the potential of direct radionuclide speciation with an emphasis on the fission products Se and Tc in highly active nuclear materials and at assessing the possible influence of the γ-radiation field surrounding highly active samples on the beamline instrumentation. While the influence of γ-radiation turned out to be negligible, initial radionuclide speciation studies by XAFS were most promising. In addition to Se and Tc speciation, the focus of these initial investigations was on the possibility for direct actinide speciation by recording corresponding L3-edge XAFS data. The registration of high quality XANES data was possible for the actinide elements U, Np, Pu and Am, as well as for Zr.

    Within the framework of the Fast Breeder Project various institutes of the KarIsruhe Nuclear Research Center operate sodium loops for corrosion studies and component tests under sodium. The operation of these loops has led to extensive experience in cleaning sodium-wetted components. This experience relates to the alcohol method, the removal of sodium by melting, storage in air, and to cleaning by means of steam. Deposition samples from radioactive sodium loops were used for decontamination experiments employing various decontaminating agents. The department concerned with the treatment of radioactive waste studied the use of molten salts and paste type cleansers for components unsuitable for mechanical decontamination, primarily with the objective to reduce the amount of radioactive waste.

    Aim of the research-project was it to increase the calculation safety of crank shaft thrust bearings in combustion engines. The project was divided in two parts: (1) A simulation program to analyze the load bearing capacity of axial bearings under mixed lubrication has been developed at the Institut fuer Maschinenelemente und Konstruktionstechnik, University of Kassel. This part of the research-project has been presented at the FVV Herbsttagung in 2003. (2) The test runs with original parts were carried out on a newly designed thrust bearing test rig at the Institut fuer Tribologie, University of Applied Sciences in Mannheim. The following presentation shows the results of part 2. The experimental results show the influence of rotational frequency, load, bearing material, lateral run-out of the tread of the crankshaft and groove pattern. These test runs will help to dimension thrust bearings more efficiently. (orig.)

    For the Fraunhofer IME, 2015 was an outstanding year, including a record-breaking operating budget of around 33.9 million euro, of which an astounding 97.1% was from third party revenues. Business contracts accounted for around 47% of our turnover, which is also an extraordinary achievement. Our research scientists won awards for excellent results in 2015. For example, one Joseph von Fraunhofer Prize 2015 went to a team of researchers from Continental Tires Germany GmbH, Fraunhofer IME and the University of Muenster, developing natural rubber from dandelions as a sustainable raw material for the rubber processing industry. This project is an excellent embodiment of the ideals of the Fraunhofer-Gesellschaft and our working approach, our aim being to perform top-level scientific research, to think in terms of ecological and economic sustainability, and to develop original solutions to key challenges. In collaboration with industrial partners, these solutions bring specific products onto the market that strengthen Welcome Germany's standing as a research and business location as well as benefiting society. By developing research activities combining different core competencies, and by integrating perspectives from diverse fields of operation, we can enhance the value of our scientific and regulatory services. The contribution of our research scientists to the drawing up of guidelines and guidance documents is valued on a national and international level. In setting up the new business field 'Sustainable Agricultural Production of Substances', we have linked our competencies in analytics, soil science, active substance research and testing, as well as secondary raw materials and feedstuffs, with the know-how of external partners in plant cultivation and geographical information systems.

    The development of hydrology with its many practical applications in water management has led to a great demand for hydrometeorological data, variables derived from meteorological measurements, and models. The report shows the many fields in which meteorological data are required in hydrology and water management. Measuring networks and methods are described and critically assessed, including remote measurement by radar and satellite. For the hydrologist, the most important variables to be derived are the regional precipitation and evaporation, each with the error source and size. Other factors of interest are the snowbreak, the expected maximum precipitation (rain), the statistical derivation of strong rain, and regionalisation methods for all variables derived. These methods are presented. The possibilities of meteorology, especially (WMO) in the field of data transmission systems are assessed. (orig./KW) [Deutsch] Die Entwicklung der Hydrologie mit ihren zahlreichen wasserwirtschaftlichen Anwendungen hat zu einem grossen Bedarf an hydrometeorologischen Daten, aus meteorologischen Messungen abgeleiteten Groessen und auch an Modellen gefuehrt.

    A suitable qualification for responsible personnel in Radiation Protection (RP) must be in general a combination of theoretical knowledge, and the ability (competency) to practice RP. While the theoretical knowledge is acquired by suitable education and by attending training courses, competency and skills can only be obtained by appropriate on-the-job training (OJT) followed by a period of work experience. From the feedback of questionnaires from 30 EU countries within the framework of the EU supported ENETRAP project it can be concluded that OJT provides better chances for future job opportunities and increases international flexibility. As result we recommend covering OJT together with education and training in the Basic Safety Standards and their guidelines for implementation. OJT should be specified by its content (syllabus, learning objectives), availability of necessary facilities and infrastructures as precondition for OJT, assessment of the competence of the participant, format of certificate, recognition of OJT, and responsibilities of host organisation and trainees. OJT should remain a key element in the remodelled 'European RP Training'. Based on these recommendations a two weeks training module on 'Occupational RP: Specificities of Waste Management and Decommissioning' designed for radiation protection professionals has been compiled at the Karlsruhe Training Centre FTU. While the first week of the pilot course focuses on the theoretical knowledge ranging from waste classification to decontamination techniques and transport of radioactive materials, the second week is addressed to practical training as OJT from clearance of radioactive waste, operative RP in the Decontamination Department to RP work in a Research Reactor under decommissioning. Special emphasis is devoted to RP aspects and active involvement of the participants in workshops and case studies. The results of the pilot run with participants from 8 different European countries are reported

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

    Integral energy concepts for housing estates require an early cooperation between architects, planners, and specialist engineers on the basis of a holistic planning approach. This is how future-oriented, sustainable concepts evolve which do justice to the multifarious requirements on the integral energy system of a housing estate. The present paper elucidates different approaches to optimising the energy efficiency of buildings such as the implementation of low-energy house concepts, building site and architectural planning, and detailed planning of heat insulation concepts, ventilation and air tightness concepts, and adapted heating systems. The solarisation of development plans has an influence on the arrangement of buildings, which are now planned to give the greatest possible passive and active solar energy gains. The authors also describe solar-assisted district heating systems for housing estates. [Deutsch] Integrale Energiekonzepte fuer Wohnsiedlungen erfordern die fruehe Zusammenarbeit von Architekten, Planern und Fachingenieuren im Rahmen einer ganzheitlichen Planung. So entstehen zukunftsweisende und tragfaehige Konzepte, die den vielschichtigen Anforderungen des Gesamtenergiesystems ``Wohnsiedlung`` gerecht werden. Im Folgenden wird die energetische Optimierung von Gebaeuden wie die Umsetzung von Niedrigenergiehaus-Konzepten, Standort und Gebaeudeplanung sowie Detailplanung in Bezug auf das Waermedaemmkonzept, Lueftungs-/Dichtheitskonzept und auf angepasste Waermeversorgungssysteme erl autert.

    Due to the increasing safety and comfort demands of the customer, the functionality of modern brake systems has grown continuously in the last years. However, implementation of the extended functionality in conventional brake hydraulics makes active electronic intervention necessary and therefore requires a lot of technical effort. In recent years the automotive supplier industry has started to develop brake systems which have electromechanical brake actuators generating the brake forces at the individual wheels. Electromechanically actuated wheel brakes need to be operated in a closed control loop. This paper introduces a new method to reconstruct the needed feedback value brake force from easy to measure signals. (orig.) [Deutsch] Aufgrund des gestiegenen Sicherheits- und Komfortbewusstseins der Fahrzeugkaeufer ist die Funktionsvielfalt moderner Bremssysteme in den letzten Jahren staendig gewachsen. Die Umsetzung der erweiterten Funktionalitaet mittels konventioneller Bremsenhydraulik ist jedoch durch den elektronischen, aktiven Eingriff sehr aufwendig. In den letzten Jahren hat daher die Automobilzulieferindustrie begonnen, Bremssysteme zu entwickeln, bei denen die Bremskraft an den einzelnen Raedern von elektromechanischen Bremsaktuatoren aufgebracht wird. Elektromechanisch betaetigte Radbremsen muessen im geschlossenen Regelkreis betrieben werden. Der vorliegende Beitrag, der im Rahmen einer Forschungskooperation zwischen Continental Teves und dem Institut fuer Automatisierungstechnik der TU Darmstadt entstand stellt ein Verfahren vor, mit dem die dafuer benoetigte Rueckfuehrungsgroesse `Bremskraft` aus einfach messbaren Signalen rekonstruiert werden kann.

    Fro, 23,7,1976 to 28.7.76 and from 8.3.76 to 9.16.76 50 pCi 131 I/m 3 , 116 pCi 133 I/m 3 und 195 pCi 135 I/m 3 were measured on an average in 11 samples of waste air from the Karlsruhe Nuclear Fuel Reprocessing Plant (WAK). During these time intervals no dissolution of fuel material was performed. From 16.9.76 to 27.10.76 18 charges of nuclear fuel were dissolved. During this period 3.3 pCi 131 I/m 3 and 7.9 pCi 133 I/m 3 were obtained as mean waste air concentrations which were higher than the lower detection limit of the method of measurement used. 244 Cm, 242 Cm, 242 Pu, 240 Pu and 238 Pu are responsible for the production of radioiodine in nuclear fuel by spontaneous fission. 244 Cm is the most important nuclide in highly active waste solutions (HAL). The cumulative fission yield is well approximated by 3% for 13 I and by 6% for 133 I. The radioiodine is set free during fuel dissolution by venting of tanks and HAL pipes and during the vritification of such solutions. The radioiodine produced by spontaneous fission is released from WAK only by venting of tanks and HAL pipes. Corresponding to the conditions of venting, air concentrations as high as 4.4 pCi 131 I/m 3 and 8.2 pCi 133 I/m 3 are expected. These concentrations agree well with air concentrations measured during the period of fuel dissolution. Based on plausible assumptions the 131 I and 133 I waste air concentrations for the period of outage are calculated from an evaporated volume of HAL in the pipes corresponding to about 10 g of 244 Cm and with 40% equilibrium between I 2 in evaporated HAL and in waste air. In the worst case 131 I-concentrations in the waste air of WAK result in an annual release of 0.2 mCi 131 I. This value is less than 1% of the authorized annual releases of 1976. For a reprocessing plant of 1,400 t/a capacity the annual expected release of 131 I lies in the mCi range. (orig.) [de

    The PVS simulation program for Windows was to be extended to the development and simulation of PV-supported equipment and small systems. The following new functions were to be integrated: a) Simulation and dimensioning of indoor power supply of systems with different light sources and independent outdoor systems. b)Integration of small wind generators in the simulation and dimensioning of isolated autonomous systems, including wind data and a component database for small wind turbines; c) Differentiation of the PVS battery model for different battery types (lead, Ni/Cd, Li etc.), optimized operating strategies and flexible dimensioning including an additional component database for battery types; d) Extensive cost analysis for PV-supported appliances and small systems, from investments to consumption, operation and maintenance. This will facilitate investment decisions and help systems of this type along in the market. All program components were designed for high flexibility. Users should be able to vary as many parameters as possible, and to generate and modify their own records. The current project focused on the user interface, i.e. input, data processing, and output. Parallel to this, the Fraunhofer ISE Institute worked on modifications of the computer hardware.

Darueber hinaus schaetzte ca. ein Viertel der Haushalte, die eine solarthermische Anlage installierten, den Einfluss der Kampagne eher hoch ein. Allerdings vermissten die Haushalte zum Teil weiterfuehrende Informationen. Auch die befragten Handwerker aeusserten eine relativ grosse Zufriedenheit mit der Kampagne. Sie nutzten die bereitgestellten Informationsmaterialien der Kampagne jedoch nur sehr selten. Die Evaluation der internen Grundlagen und Prozesse fuehrt zu ambivalenten Ergebnissen: Beispielsweise ist es der Kampagne auf der einen Seite gelungen, eine breite und heterogene Traegerschaft zu gewinnen und flexibel auf aeussere Anforderungen zu reagieren. Auf der anderen Seite stellten sich Probleme in der Steuerung und im Konfliktmanagement ein. Hierzu trugen u.a. eine nicht ausreichend integrierte Projektplanung sowie strukturelle Unterschiede zwischen den Partnern bei. Die Evaluation muendet in der zentralen Empfehlung, die Kampagne in modififizierter Form fortzusetzen. Verbesserungsmoeglichkeiten sehen die Evaluatoren u.a. in der verstaerkten Einbindung regionaler Aktvitaeten.

    For safe and environmentally acceptable operation of cryotechnical and refrigerating sytems, the permeation characteristics of the elastomers and fibre-reinforced materials must be known. While elastomers are used primarily as sealing materials of refrigeration systems, fibre-reinforced materials are used increasingly in containers for supercooled liquids like LN2, LH2, and LH3. Measuring systems and methods were developed at the Institut of Ventilation and Refrigeration Engineering at Dresden (Institut fuer Luft- und Kaeltetechnik, Dresden) that enable quantitative statements on the permeation characteristics as a function of temperature.

The SRU sees a need for greater transparency here to enable public authorities to react swiftly whenever evidence of health or environmental risks arises. Consumers should in principle enjoy freedom of choice. For this reason the SRU recommends creating a registry of nanoproducts and supplementation of existing labelling requirements. [German] In diesem Sondergutachten gibt der Sachverstaendigenrat fuer Umweltfragen (SRU) Empfehlungen fuer einen verantwortungsvollen, vorsorgeorientierten Umgang mit dieser Technologie. Ziel ist es, Innovationen zu ermoeglichen, aber auch Risiken fruehzeitig zu erkennen und zu mindern. Der SRU sieht dringenden Handlungsbedarf bei der Regulierung von Nanomaterialien und fordert mehr Transparenz bei Verbraucherprodukten ein. Sobald ein begruendeter Anlass zur Besorgnis besteht, muss nach dem Vorsorgeprinzip gehandelt und zwischen Risiken und Chancen abgewogen werden. Um dies zu ermoeglichen, sind zahlreiche rechtliche Aenderungen erforderlich. Nanomaterialien und Nano-Produkte unterliegen grundsaetzlich dem Stoff-, Produkt- und Umweltrecht. In der Praxis fuehren aber die Besonderheiten von Nanomaterialien dazu, dass nicht alle rechtlichen Instrumente greifen. So werden Nanomaterialien bei der Registrierung von Chemikalien und bei der Zulassung von Produkten nicht immer separat erfasst und damit bewertet. Der SRU empfiehlt, solche nanospezifischen Regelungsluecken schnell zu schliessen. Dazu ist es notwendig, Nanomaterialien verbindlich zu definieren, sie grundsaetzlich bei der Risikobewertung von Chemikalien wie eigenstaendige Stoffe zu behandeln und mit einem eigens auf sie zugeschnittenen Datensatz zu registrieren. Dabei duerfen die Risiken von Nanomaterialien nicht pauschal bewertet werden, weil manche Materialien nach heutigem Kenntnisstand unbedenklich sind, waehrend bei anderen ein Risikopotenzial besteht. Einen Anlass zur Besorgnis sieht der SRU vor allem bei der Verwendung von

    presence of non condensable gases. For the heat transfer process an effective thermal conductivity of the liquid/vapour mixture accounts for partial vapour blanketing of the fuel particles. Numerical results are in general consistent with those obtainable from the first code. A survey of the various fragmentation mechanisms of UO 2 in sodium was done. It was concluded that 'vapour bubble and collapse' seems to be the most probable fragmentation mechanism in the case of UO 2 /sodium systems. For this reason work was focussed on modelling this mechanism. A preliminary model was given. Work is progressing. It is planned to couple the FCI theoretical model No. 1 developed at Karlsruhe to the american REXCO code which is available at Ispra. Work is being completed. The FCI subroutine is already available

    1983-06-01

    After developing a procedure for the ''Testing of Surface Coating Materials for the Decontamination'' about 900 different surface coating materials had been tested and evaluated for the domestic and foreign industry. The results prove the following basic facts: Surface coatings, low in porosity, forming a smooth surface and containing limited amounts of filler are in the majority very effectively decontaminated if they are prepared of chemically stable, water repellent materials; Decontamination results are drastically poorer if the degree of filling of the materials is high especially if hygroscopic fillers and/or hygroscopic colouring matters are used. Currently available cleansers and washing powders used for decontamination did not fulfill the three basic demands for a decontamination agent: high efficiency, small foam generation and sufficient thermal stability. Therefore for the decontamination of walls, floors, etc. a water delutable, liquid cleanser was developed. In the same context a washing powder was optimized for the decontamination of contaminated clothing. The experiments on the decontamination of stainless steels ended up with the formulation of a pickling paste. Furthermore all investigations were aimed at a minimization of the waste generation by the decontamination process. This resulted in decontamination techniques, in which the decontaminating agents were applied in thin layers. A comparison of the currently practiced dipping technique with the coating technique showed that the latter one gave the better decontamination results and that the amount of decontamination waste was reduced.

It is envisaged that they will last through the whole vehicle life. They can be used in passenger cars, industrial vehicles, high-speed trains, aircraft and in safety brakes in machines, plants and haulage systems. [German] Im Rahmen der Raumfahrt-Forschung wurde vom Deutschen Zentrum fuer Luft- und Raumfahrt (DLR) das Fluessigsilicier-Verfahren zur Herstellung von keramischen Verbundwerkstoffen entwickelt.

Darueber hinaus zeigten Untersuchungen ein hohes Anwendungspotenzial fuer neue Bremsen mit deutlich verbesserten Reibungs- und Verschleisseigenschaften. Weiterentwicklungen des keramischen Gefueges fuehrten zu innovativen Leichtbau- bzw. Hochleistungs-Bremsen auf der Basis dieser harten und hitzebestaendigen Verbundwerkstoffe. Bereits mit serienmaessigen Bremsbelaegen wurden die heute geltenden Verschleiss- und Reibwertanforderungen teilweise weit uebertroffen.

    In the context of their aerospace research activities, DLR (Deutsches Zentrum fuer Luft- und Raumfahrt) developed a new process for producing ceramic fibre composite materials that are extremely light and tough. Apart from their applications in aerospace engineering, they have great potential for motor brakes with improved friction and wear characteristics. Excellent results were achieved with the new materials even with conventional brake liners. With customised liners, brake life may be prolonged to match the car life. Further applications are expected in trucks for transport in hazardous materials, high-speed trains, aircraft, industrial machinery and plants, and conveyor systems.

    Energy costs caused by heating, ventilation, air-conditioning and lighting systems, represent a significant portion of the total operating costs of a building. continuously rising prices of gas, oil and electricity increase the cost pressure on the building operators and users: energy efficiency is becoming a major factor for the competitiveness of a company. In the manufacturing sector, trade and hotel the energy costs have a direct impact on the company's margins. Thus, the willingness to invest in energy saving measures increased. [German] Energiekosten, verursacht durch Heizungs-, Lueftungs-, Klima- und Beleuchtungsanlagen, stellen einen signifikanten Anteil der Gesamtbetriebskosten eines Gebaeudes dar.

Im produzierenden Gewerbe, im Handel und im Hotelgewerbe haben Energiekosten einen direkten Einfluss auf die Margen des Unternehmens. Dadurch erhoeht sich die Bereitschaft, in Energiesparmassnahmen zu investieren.

  5. Evolutionary institutionalism.

    Science.gov (United States)

    Fürstenberg, Dr Kai

    Institutions are hard to define and hard to study. Long prominent in political science have been two theories: Rational Choice Institutionalism (RCI) and Historical Institutionalism (HI). Arising from the life sciences is now a third: Evolutionary Institutionalism (EI). Comparative strengths and weaknesses of these three theories warrant review, and the value-to-be-added by expanding the third beyond Darwinian evolutionary theory deserves consideration. Should evolutionary institutionalism expand to accommodate new understanding in ecology, such as might apply to the emergence of stability, and in genetics, such as might apply to political behavior? Core arguments are reviewed for each theory with more detailed exposition of the third, EI. Particular attention is paid to EI's gene-institution analogy; to variation, selection, and retention of institutional traits; to endogeneity and exogeneity; to agency and structure; and to ecosystem effects, institutional stability, and empirical limitations in behavioral genetics. RCI, HI, and EI are distinct but complementary. Institutional change, while amenable to rational-choice analysis and, retrospectively, to criticaljuncture and path-dependency analysis, is also, and importantly, ecological. Stability, like change, is an emergent property of institutions, which tend to stabilize after change in a manner analogous to allopatric speciation. EI is more than metaphorically biological in that institutional behaviors are driven by human behaviors whose evolution long preceded the appearance of institutions themselves.

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

    It has been confirmed by practical project experience that integral energy concepts are an excellent basis for the construction of energy-efficient buildings. In the extreme case buildings can even be self-sufficient in their energy supply. Uniting the responsibility for the overall energy and technology concept in the hands of a single contractor can help reduce frictional losses between those involved in the planning as well costs. A good example of this is the use of a simulation calculation for the prescribed demonstration of proper heat insulation. The presented projects show that it is possible to construct ecologically answerable buildings at attractively low costs. The presented concepts appear particularly convincing from the viewpoint of long-term maintenance of value and user-specific advantages such as agreeable working conditions. [Deutsch] Die konkreten Projekterfahrungen bestaetigen, dass durch integrale Energiekonzepte sowohl im Verwaltungs- als auch im Wohnungsbau hervorragende Voraussetzungen fuer energiesparende Gebaeude geschaffen werden koennen. Im Extremfall kann sogar eine autarke Energieversorgung erreicht werden. Durch Zusammenfassung der Gesamtverantwortung fuer das Energie- und Technikkonzept in einer Hand koennen Reibungsverluste zwischen den Planungsbeteiligten reduziert und Kosten gesenkt werden. Ein Beispiel hierfuer ist die Verbindung des vorgeschriebenen Waermeschutznachweises mit einer fuer alle Beteiligten wesentlich aussagekraeftigeren Simulationsrechnung. Die vorgestellten Projekte zeigen, dass oekologisch sinnvolle Gebaeude auch zu oekonomisch attraktiven Kosten erstellt werden koennen, wobei insbesondere der Aspekt des langfristigen Werterhalts und die nutzerspezifischen Vorteile, z.B. durch angenehmere Arbeitsbedingungen, fuer die vorgestellten Konzepte spricht.

    bzw. -kompensation werden zurzeit untersucht oder schon in der Klinik angewendet. Die Sonographie ist eine vielversprechende Option, die nun kurz vor der klinischen Implementierung steht. Hoher Weichteilkontrast, Echtzeitfaehigkeit, Verzicht auf ionisierende Strahlung sowie relativ geringe Anschaffungskosten zeichnen den Ultraschall besonders fuer diesen Zweck aus. Ultraschallbewegungstracking ist ein bildbasierter Ansatz, d. h. das Zielvolumen oder eine damit verbundene Struktur werden direkt beobachtet und deren Bewegung automatisch auf dem Ultraschallbild nachverfolgt. Diverse Algorithmen stehen derzeit zur Verfuegung, die sowohl aus 2-D- als auch 3-D-Bildern die aktuellen Koordinaten einer Zielstruktur liefern. Die Auswahl eines passenden Schallfensters ist jedoch nicht trivial, und ein Goldstandard fuer die Positionierung und Halterung des Schallkopfs wurde noch nicht erarbeitet. Ausserdem sind die Verarbeitung der Koordinateninformation an der Therapieeinheit sowie die dynamische Anpassung des Strahlfeldes grosse Herausforderungen. Es ist offen, ob sich Ultraschallbewegungstracking in der klinischen Routine etabliert, obwohl alle technischen Voraussetzungen als erfuellt angesehen werden koennen, sodass weiterhin spannende Entwicklungen in diesem Forschungsfeld zu erwarten sind.

    Institutional entrepreneurship pays specific attention to the process and outcomes of agents who are willing and capable of changing institutions. It has some common ground with the political entrepreneur, a concept that proposes change in norms and institutions because of commitment and activities...... of agents or organisations in the policy arena. The present chapter understands institutional entrepreneurship as the process of changing institutionalised practices. Based on a literature review, it describes the triggers, activities and potential effects of institutional entrepreneurs. The chapter...... concludes by tentatively arguing that political entrepreneurs can be institutional entrepreneurs, but institutional entrepreneurship can be considered as the broader concept that incorporates strategies and visions as well as interpretative-discursive power into the conceptual framework....

  15. Deformation integrity monitoring for GNSS positioning services including local, regional and large scale hazard monitoring - the Karlsruhe approach and software(MONIKA)

    Jaeger, R.

    2007-05-01

    GNSS-positioning services like SAPOS/ascos in Germany and many others in Europe, America and worldwide, usually yield in a short time their interdisciplinary and country-wide use for precise geo-referencing, replacing traditional low order geodetic networks. So it becomes necessary that possible changes of the reference stations' coordinates are detected ad hoc. The GNSS-reference-station MONitoring by the KArlsruhe approach and software (MONIKA) are designed for that task. The developments at Karlsruhe University of Applied Sciences in cooperation with the State Survey of Baden-Württemberg are further motivated by a the official resolution of the German state survey departments' association (Arbeitsgemeinschaft der Vermessungsverwaltungen Deutschland (AdV)) 2006 on coordinate monitoring as a quality-control duty of the GNSS-positioning service provider. The presented approach can - besides the coordinate control of GNSS-positioning services - also be used to set up any GNSS-service for the tasks of an area-wide geodynamical and natural disaster-prevention service. The mathematical model of approach, which enables a multivariate and multi-epochal design approach, is based on the GNSS-observations input of the RINEX-data of the GNSS service, followed by fully automatic processing of baselines and/or session, and a near-online setting up of epoch-state vectors and their covariance-matrices in a rigorous 3D network adjustment. In case of large scale and long-term monitoring situations, geodynamical standard trends (datum-drift, plate-movements etc.) are accordingly considered and included in the mathematical model of MONIKA. The coordinate-based deformation monitoring approach, as third step of the stepwise adjustments, is based on the above epoch-state vectors, and - splitting off geodynamics trends - hereby on a multivariate and multi-epochal congruency testing. So far, that no other information exists, all points are assumed as being stable and congruent reference

    This assessment is a feasibility study according to ISO 14024. It deals with the question whether an ecolabel is suitable for wood pellet heating systems and how concrete criteria for an ecolabel for wood pellet heating plants could be specified. The study begins with a comprehensive market analysis in order to identify possible plants for which an ecolabel would make sense. In the main part of the study, the environmental relevance of the chosen plants is analysed. For this analysis, plant manufacturers were interviewed and a comparison between wood pellet heating systems and heating systems which use gas, oil or wood was carried out. On the basis of this analysis, it was possible to derive a number of criteria which were discussed with company representatives and other experts in this field. As a result of this dialogue and the investigation process as a whole, the introduction of an ecolabel for wood pellet heating plants can be recommended. Wood pellet heating systems are characterized by their high level of automatation and the use of standardized fuels with constant high quality. Thus, they reach high combustion quality with low emission rates, and risks of misuse are minimized. They may contribute to the increased use of renewable energies and thereby to the achievement of climate protection goals. The proposed certification principles comprise requirements regarding (a) the efficient energy use (efficiency factor under partial load and nominal load, plant's supplementary energy consumption), (b) emission values for CO, NO{sub x}, dust and organic substances, (c) the offer of additional services, as well as (d) requirements with regard to the operating instructions.

    Passive radon /sup 222/Rn dosimeters employing particle detectors are widely used in concentration (p Ci/l) measurement in houses, mines and other areas of activity. These dosimeters yield track density which is needed to be converted into physically meaningful parameter of radon concentration in either p Ci/l or Bq m/sup -3/. Therefore, it is required to know the separate contributions of /sup 222/Rn and its progeny. In the present study we have measured the concentration of /sup 222/Rn and its daughters (/sup 218/Po and /sup 214/Po) separately in the Karlsruhe diffusion chamber radon dosimeter, with and without a filter, as a function of time by an active method using a surface barrier detector. The build up behavior of radon and its two daughters (/sup 218/Po and /sup 214/Po) as a function of time was studied by plotting the area under each peak versus collection time. The differential curves and the relative concentration of radon daughters as a function of time were also studied. The concentration of radon and its daughters shows a somewhat linear build up as a function of time for the presently studied time periods. The results of this experiment are expected to be useful in converting the integrated alpha track density as measured by a particle track detector, (used in passive radon dosimetry) to radon concentration levels and for determination of equilibrium factor.

Two objectives of the experimental program have been defined: testing of the experimental setup and a first validation of FE models. The design and manufacturing of mock-up representing about 1/3 of the heated zone of an ITER Test Blanket Module (TBM) First Wall is discussed. A modular attachment system concept has been developed for the fixation of the mock-up in order to be able to generate different stress distributions and levels on the plate, which is confirmed by thermo-mechanical analyses. The HELOKA facility is able to provide a TBM relevant helium cooling system and to generate the required surface heat flux by an electron beam gun. An installed IR camera can be used to measure the temperature distribution on the surface.

  3. ANITA-IEAF activation code package - updating of the decay and cross section data libraries and validation on the experimental data from the Karlsruhe Isochronous Cyclotron

    ANITA-IEAF is an activation package (code and libraries) developed in the past in ENEA-Bologna in order to assess the activation of materials exposed to neutrons with energies greater than 20 MeV. An updated version of the ANITA-IEAF activation code package has been developed. It is suitable to be applied to the study of the irradiation effects on materials in facilities like the International Fusion Materials Irradiation Facility (IFMIF) and the DEMO Oriented Neutron Source (DONES), in which a considerable amount of neutrons with energies above 20 MeV is produced. The present paper summarizes the main characteristics of the updated version of ANITA-IEAF, able to use decay and cross section data based on more recent evaluated nuclear data libraries, i.e. the JEFF-3.1.1 Radioactive Decay Data Library and the EAF-2010 neutron activation cross section library. In this paper the validation effort related to the comparison between the code predictions and the activity measurements obtained from the Karlsruhe Isochronous Cyclotron is presented. In this integral experiment samples of two different steels, SS-316 and F82H, pure vanadium and a vanadium alloy, structural materials of interest in fusion technology, were activated in a neutron spectrum similar to the IFMIF neutron field.

    1987-05-01

    6 Li-induced break-up reactions have been investigated at reaction angles in extreme forward direction including O 0 with the Karlsruhe Magnetic Spectrograph 'Little John'. The experiments were characterized by the minimization of the high experimental background that dominates at small emission angles. Inclusive alpha-particle and deuteron spectra from the bombardement of 12 C- and 208 Pb-targets with 156 MeV 6 Li-ions have been measured. Below the grazing angle the Coulomb interaction shows a distinct influence on the angular distributions of the fragments. A simple spectator-model and a more realistic description within the DWBA-formalism largely allows a reproduction of the data. In the light of the reverse reaction α + d → 6 Li + γ at small α-d-relative energies, which is of considerable interest for astrophysics, a particle-particle-coincidence measurement with θ α = 5 0 and θ d = -2 0 has been performed. The result could be reproduced reasonably well by a simple Monte-Carlo-simulation. Beside the treatment of a physical problem this work deals with the start-up of the magnetic spectrograph and the clarification of spectrograph specific questions concerning the data reduction.

    The radiological impact by radioactive offgas and exhaust air on the environment of the Karlsruhe Nuclear Research Center (KNRC) is calculated every year and compared with the permissible equivalent doses. This report includes both the forecasted maximum doses from maximum releases scheduled for the year 1976 and the actual doses of 1975 based on the measured releases in 1975. According to the various irradiation mechanisms of the nuclides emitted, the following doses are indicated, each calculated for an adult person: whole body dose by γ-irradiation and tritium inhalation, skin dose by external β-irradiation, lung dose by aerosol inhalation, bone dose by plutonium inhalation, and effective integral dose. The maximum infant thyroid dose due to iodine ingestion via the pasture-cow-milk-pathway is also calculated. The respective maximum doses indicate that the dose limits of 30 mrem/a whole body dose (adult) and 90 mrem/a thyroid dose (Infant) which are to be observed by the KNRC since the year 1975 are not exceeded at any point, provided the emissions remain below the scheduled maximum level. The doses in 1975 were markedly below the dose limits mentioned above. This is even true when partial body and organ doses are integrated in an 'effective dose'. (orig.) [de

    This paper offers a brief overview of the historical and technical aspects of aquifer thermal energy storage and its use potential in commercial buildings in Canada. Aquifer thermal energy storage systems are now attractive both for new commercial buildings in Canada and for some already existing ones. This holds true especially of the Atlantic region, where fuel costs are rising and electric power rates vary according to the time of day. The simple pay-back period for ATES systems is between zero and five years. The economic aspects of the use of ATES systems in buildings are pointed out.

    The law for recycling and waste demands the utilization also for waste of asbestos cement (ac). The procedure of thermal utilization of ac in the flame of a rotary cement kiln was developed and patented by the research institute IBU-tec Weimar, Germany. The ac-material has to be pre-pulverized and grinded to a degree of fineness of R{sub 90}<15%. Considerations of safety engineering lead to the idea of common fine grinding of old oil (oo) and ac. This new procedure was searched in FuE-project in 1998/99 (financial support by BMBF). A mash of ac and oo was generated as a utilization product ready for firing which was injected into the flame of the rotary cement kiln. This particles of ac smelt to spherical shaped particles at a temperature above 1500 C. They were utilized by clinker formation. The material and gas stream leaving the kiln does not contain fibres of asbestos. This was demonstrated in a small equipment burning test. The industrial realization concerning cement plant Ruedersdorf, near Berlin, was searched, technologically described and safety engineeringly and financially assessed by a project study. Process-technical and financial advantages were seen for the dry fine grinding. The wet fine grinding with old oil could be used in cement plants using old oil as fuel. (orig.) [German] Das Kreislaufwirtschafts- und Abfallgesetz (1994) fordert u.a. die stoffliche Verwertung auch fuer Asbestzementabfaelle (AZ). Das vom Institut fuer Baustoff- und Umweltschutz-Technologie Weimar 1995 entwickelte und patentierte Verfahren zur thermischen Verwertung von AZ in der Flamme eines Zementdrehrohrofens erfuellt diese Forderung. Das AZ-Material muss vorzerkleinert und bis zur Rohmehlfeinheit (R{sub 90}<15%) feingemahlen werden. Sicherheitstechnische Ueberlegungen fuehrten zu der Idee, die Feinmahlung zusammen mit Altoel (AOe) zu erproben. Diese Verfahrensvariante wurde im Rahmen eines FuE-Projektes 1998/99 untersucht (finanzielle Foerderung durch das BMBF). Als

    The installation of a radiology information system (RIS) connected to a hospital information system (HIS) and a picture archiving and communications system (PACS) seems mandatory for a nuclear medicine department in order to guarantee a high patient throughput. With these systems a fast transmission of reports, images to the in- and out-patients' wards and private practitioners is realized. Therefore, since April 2000, at the department of nuclear medicine of the university of Wuerzburg a completely DICOM based PACS has been implemented in addition to the RIS. With this system a DICOM based workflow is realized throughout the department of nuclear medicine for reporting and archiving. The PACS is connected to six gamma-cameras, a PET scanner, a bone densitometry system and an ultrasound device. The volume of image data archived per month is 4 GByte. Patient demographics are provided to the modalities via DICOM-Worklist. With these PACS components a department specific archive purely based on DICOM can be realized. During the installation process problems occurred mainly because of the complex DICOM standard for nuclear medicine. Related to that is the problem that most of the software implementations still contain bugs or are not adapted to the needs of a nuclear medicine department (particularly for PET). A communication software for the distribution of nuclear medicine reports and images based on techniques used for the worldwide web is currently tested. (orig.) [German] Fuer eine nuklearmedizinische Klinik ist ein Klinikinformationssystem (KIS) gekoppelt mit einem Radiologieinformationssystem (RIS) sowie einem Bildarchivierungs- und Verteilungssystem (PACS) unabdingbar, um einen schnellen Patientendurchsatz sowie die zeitnahe Uebermittlung von Befunden inklusive nuklearmedizinischen Bildern an zuweisende Stationen, Ambulanzen und externe Zuweiser zu gewaehrleisten.

    The current energy concept of Sachsen-Anhalt dates back to 2004. Since then, boundary conditions have changed. International energy markets are characterized by growing demand and rising energy prices. This has influenced Germany as well. Further, sustainable power supply and global climate change have become relevant issues during the past few years. Against this background, Sachsen-Anhalt intends to modify its energy concept. The first step will be the provision of a current information and data base on all aspects of world, national and state energy supply and all relevant boundary conditions. The 'Energiestudie 2007' was prepared by Institut fuer Energetik und Umwelt gGmbH. The contents are based on current studies and investigations. The 'Energiestudie' will provide an information base which may be maintained and updated by actors of Sachsen-Anhalt. (orig.)

    There is an increasing demand for integrated building concepts in order to reduce energy consumption. Building design, construction and heating, ventilation and air-conditioning (HVAC) technology are decisive in this respect. Thus, an essentially higher energy efficiency is achieved and solar energy becomes the main energy source. An `active building envelope` assumes the task of controlling the energy flows between inside and outside. This paper reports on new components, system concepts and planning tools for solar building. (orig.) [Deutsch] Fuer zukuenftige Bauten werden in hohem Masse Forderungen nach integrierten Konzepten zur Begrenzung des Energieverbrauchs gestellt. Gestalt, Konstruktion und Klimatechnik sind dabei massgebliche Einflussfaktoren. Hierdurch wird eine wesentlich hoehere Energieeffizienz erzielt und Solarenergie kann die uebrigen Energiequellen zurueckdraengen. Eine `aktive Gebaeudehuelle` uebernimmt die Aufgabe, den Energiefluss zwischen Innen und Aussen zu steuern. Der Beitrag berichtet ueber neue Komponenten, Systemkonzepte und Planungswerkzeuge fuer das Solare Bauen. (orig.)

    In some of the federal states of Germany the licensing of new or the laying or existing high-voltage overhead lines requires an environmental impact assessment. For many utility companies, however, environmental impact assessments for high-voltage lines are virgin territory. Experience shows that preparing the documentation is not a major problem. Questions usually arise over details such as the calculation of possible incidents or the comparison of different layouts. The authors describes general approaches and strategies and looks at specific problems. (orig.)

    Methods are developed that allow the registration and mapping of waste heat emissions on a grid of 2 x 2 km 2 . They are directly applicable in the Federal Republik of Germany and may be extended to neighbouring countries. Such a mapping provides the distribution of anthropogeneous waste heat emissions in space and time and serves in the case of the upper Rhine Valley as a basis for the numerical evaluation of climate modification by man. In a close approximation the distribution of waste heat is equal to the distribution of energy consumption. Therefore, the first step is the registration and mapping of energy consumption. Data about the consumption of the most important types of energy such as coal, fuel oil, gas, electricity etc. are available only partially and on the level of administrative units which are considerably larger than the grid size. Therefore, models were developed which allow to determine energy consumption on the commune and grid level with the help of local structural data like the distribution of population, households, traffic etc. The second step to be taken is the transformation of energy of energy consumption into waste heat emissions categorized in terms of the components convection, radiation, latent heat and discharge of heated water. Energy consumption and waste heat were determined separately for the various sectors of economy. Large sources in the industrial and energy supply sectors were analyzed individually by questionnaires. The results obtained with foresaid methods in the districts of Rastatt and Baden-Baden and in the township of Karlsruhe are presented. (orig.) 891 HP [de

    The paper describes the use of online simulation for prognosticating plant behaviour, training plant operators, and for obtaining state data not to be obtained otherwise. Whereas, for the mathematical modelling of the process, the established approaches Activated Sludge Model (ASM) 1 and 2 could be reverted to, new methodics needed to be developed for continuous model tracking in order to solve the conflict between a large number of parameters in the model and scarce online measuring data on the spot. The result is a practicable solution which harnesses available knowledge concerning the significance of suitable parameters for model adaptation. First of all, essential demands on and objectives of a process observer for sewage treatment plants are elaborated. Then a software system is described with reference to successful pilot installations which permits model-based process control and remote monitoring of sewage treatment plant. (orig.) [German] Der Beitrag beschreibt die Nutzung der Online-Simulation fuer die Prognose des Anlagenverhaltens, das Training der Anlagenfahrer und die Gewinnung ansonsten nicht messbarer Zustandsinformationen.

    With their high efficiency and modular structure, fuel cells are an attractive option for decentral power supply. An important component of decentral power supply systems is the power-electronic control element for supply of electric power from the fuel cell to the three-phase electricity grid. Control elements can be constructed of a unidirectional DC/DC converter with a current inverter connnected in series. The investigation focused on the development of the DC/DC converter with minimum constructional and control requirements and optimum adaption of the DC/DC converter to the characteristics of the fuel cell. (orig.) [German] Die Brennstoffzelle stellt mit ihrem hohen Wirkungsgrad und ihrem modularen Aufbau eine attraktive Option fuer die Verwendung in einem dezentralen Energieversorgungssystem dar. Eine wichtige Komponente des dezentralen Energieversorgungssystems sind die leistungselektronischen Stellglieder fuer die Einspeisung der elektrischen Energie aus der Brennstoffzelle in das dreiphasige Netz. Die leistungselektronischen Stellglieder koennen aus einem undirektionalen DC/DC-Wandler und einem nachgeschalteten Wechselrichter realisiert werden. Die Entwicklung des DC/DC-Wandlers mit einem moeglichst geringeren Bauelemente- und Steuerungsaufwand fuer diese leistungselektronischen Stellglieder und die Anpassung des DC/DC-Wandlers an die Eigenschaften der Brennstoffzelle war das Ziel dieser Arbeit.

    Institutions formalize the intuitive notion of logical system, including both syntax and semantics. A surprising number of different notions of morphisim have been suggested for forming categories with institutions as objects, and a surprising variety of names have been proposed for them. One goal of this paper is to suggest a terminology that is both uniform and informative to replace the current rather chaotic nomenclature. Another goal is to investigate the properties and interrelations of these notions. Following brief expositions of indexed categories, twisted relations, and Kan extensions, we demonstrate and then exploit the duality between institution morphisms in the original sense of Goguen and Burstall, and the 'plain maps' of Meseguer, obtaining simple uniform proofs of completeness and cocompleteness for both resulting categories; because of this duality, we prefer the name 'comorphism' over 'plain map.' We next consider 'theoroidal' morphisms and comorphisims, which generalize signatures to theories, finding that the 'maps' of Meseguer are theoroidal comorphisms, while theoroidal morphisms are a new concept. We then introduce 'forward' and 'semi-natural' morphisms, and appendices discuss institutions for hidden algebra, universal algebra, partial equational logic, and a variant of order sorted algebra supporting partiality.

    1988-01-01

    The institutional obligation is to act to meet primary responsibilities in the face of risks. There are risks involved in taking action, both of a quantifiable and unquantifiable nature. This paper explores weighing the risks, choosing approaches that balance primary obligations with broader ones, and presenting ethical philosophies upon which policies and strategies are based. Federal government organizations and utilities--and Bonneville Power Administration qualifies as both--have a variety of responsibilities to the public they serve. The common responsibility is that of service; for Bonneville the primary responsibility is to serve the energy related needs. It is this primary institutional obligation, as it relates to other responsibilities--and the resulting strategy for handling indoor air quality in Bonneville's new homes program--that this paper examines

    The fabrication of uranium-plutonium oxide fuel started in Forschungszentrum Karlsruhe and at ALKEM company to begin for the criticality experiments in the SNEAK reactor and subsequently for stationary fuel pin irradiations in the FR2, BR2, DFR, Rapsodie, Phenix and KNK II reactors. The production methods comprised first the mechanical blending of UO2 and PuO2 followed by direct pressing and sintering of the pellets, later the advanced methods such as optimized comilling and ammonium uranyl plutonyl coprecititation. The fabrication of pellets was described in the main, further the alternative fuel pin manufacturing processes by vibrational compaction and hot-impact densification were discussed. The first capsule and pin irradiations in the FR2 and BR2 reactors contributed to the assessment of the maximum operation parameters within the fuel pin development such as linear heat rating, cladding temperature and burnup. Subsequently, small-bundle and largebundle irradiations were made in fast reactors in cooperation with Interatom company in order to verify the specifications for the commercial fast reactor SNR 300. Milestones were the maximum burnup of 175 GWd/t metal, corresponding 18.6 % of the heavy atoms, obtained in one of the KNK II fuel pin assemblies, and the displacement rates in the cladding materials of 140 dpa NRT attained in the Phenix reactor. Higher implications gained later the stationary irradiations of defected mixed-oxide pins, the mild fuel pin transient operations, the local blockage experiments and the severe hypothetic accidents in the respective Siloe, HFR, BR2 and CABRI reactors. These experiments were made solely in international partnership. Further activities were the chemical analyses of solid residues and coprecipitations of irradiated mixed-oxide fuels in the head-end of the reprocessing. All these actions were coordinated in the then fast breeder project. Furthermore, irradiated fuels and fuel pins of other reactor types were

Direct co-combustion of sewage sludge in coal dust furnaces is a simple concept, but it is useful provided that co-combustion has no negative effects in terms of performance, emissions and residue disposal. Externally dried sewage sludge has a residual water content in the same range as coal dust. The effects of co-combustion are discussed, and the experimentally determined effect in terms of emissions and residues is presented.

Pyrolysis of the sewage sludge and use of the resulting gas as a reduction agent for denitrification may reduce negative effects of co-combustion on performance, emissions and residues.(orig) [Deutsch] Am Institut fuer Verfahrenstechnik und Dampfkesselwesen (IVD) der Universitaet Stuttgart werden an Versuchsanlagen verschiedene Verfahren zur thermischen Nutzung von Klaerschlaemmen in Verbindung mit Kohlenstaufeuerungen untersucht. Die direkte Mitverbrennung von Klaerschlamm in Kohlestaubfeuerungen ist ein einfaches Konzept, das dann sinnvoll ist, wenn die Mitverbrennung keine negativen Auswirkungen auf Betrieb, Emissionen und Verwertung der Rueckstaende mit sich bringt. Bei einer externen Trockung weist der Klaerschlamm einen aehnlichen Wassergehalt wie der Auslegungsbrennstoff von Steinkohlenstaubfeuerungen auf. Die moeglichen Auswirkungen der Mitverbrennung von Klaerschlamm werden diskutiert und der im Versuch ermittelte Einfluss auf Emissionen und Reststoffe vogestellt. Durch Vorschaltung einer Pyrolyse des Klaerschlamms und Nutzung des erzeugten Gases als Reduktionsmittel zur Entsticklung kann die Auswirkung der Mitverbrennung auf Betrieb, Emissionen und Reststoffe der Feuerungsanlage vermindert werden.

    The study of M&As is dominated by positivist and functionalist world views and the use of quantitative methods. Although extant research also uses qualitative and mixed methods, it can be criticized for viewing its subject matter through an abstract and external lens. The researcher is placed in ......, and point to some of the problems in M&A studies identified through this lens. Finally, we argue why institutional ethnography, in comparison with other methods of inquiry, is particularly fruitful in the study of mergers and acquisitions....

    Within the frame of this project, a concept for setting up exemplary emission inventories for water was put forward. An overview is given of the international activities on emission inventories and the status of national emission inventories. Based on the data situation in Germany, it was necessary to include both plant-specific, aggregated and calculated data of the point sources in the inventories. Due to their increasing significance, diffuse material emissions into water were also taken into account. Based on the conceptual work, exemplary emission inventories were compiled for nitrogen, phosphorous and adsorbable organic combined halides (AOX) as well as the heavy metals arsenic, cadmium, chrome, copper, mercury, nickel, lead and zinc. These were evaluated according to the areas of origin (sectors) or the emission paths as well as according to the large river basins Danube, Rhine, Ems, Weser, Elbe, Oder, North Sea and Baltic Sea. In addition, lists of the ten largest industrial direct dischargers were compiled. (orig.) [German] Im Rahmen dieses Vorhabens wurde ein Konzept fuer die Erstellung von beispielhaften Emissionsinventaren fuer Gewaesser erarbeitet. Es wird ein Ueberblick ueber die internationalen Aktivitaeten zu Emissionsinventaren und den Stand beim Aufbau von nationalen Emissionsinventaren gegeben. Auf Grund der Datensituation in Deutschland war es erforderlich, dass sowohl anlagenspezifische als auch aggregierte sowie berechnete Daten der Punktquellen in die Inventare einbezogen wurden. Wegen ihrer zunehmenden Bedeutung werden die diffusen Stoffeintraege in die Gewaesser ebenfalls beruecksichtigt. Aufbauend auf den konzeptionellen Arbeiten wurden beispielhafte Emissionsinventare fuer Stickstoff, Phosphor und adsorbierbare organisch gebundene Halogene (AOX) sowie die Schwermetalle Arsen, Cadmium, Chrom, Kupfer, Quecksilber, Nickel, Blei und Zink zusammengestellt.

    Purpose: For preoperative staging of colorectal cancer a CT scan is frequently performed. This report examines the sensitivity of CT for regional lymph node metastasis of colorectal cancer using different criteria. Materials and methods: Preoperative CT scans of 153 patients with colorectal cancer were analyzed using different criteria for N1. The results were then compared to the postoperative histological findings. Results: For N1=lymph nodes (LN)>1 cm the sensitivity was 47%. For N1=LN>1 cm or an increased number of LN<1 cm the sensitivity was 71%. In patients with a primary tumor seen on CT, sensitivity rose to 87%. Discussion: Evidence of regional nodal metastatic disease is only relevant for rectal cancer, colon polyps, and for locally excised tumors when considering present surgical concepts for the treatment of colorectal cancer. In these cases CT analysis using the broadened criteria for N1 proposes a valuable argument regarding possible preoperative radiotherapy or an operative revision. (orig.) [Deutsch] Die Sensitivitaet fuer den Nachweis regionaerer Lymphknotenmetastasen kolorektaler Karzinome wurde unter Anwendung verschiedener Kriterien fuer das N1-Stadium an Patienten mit histologisch gesichertem Lymphknotenbefund untersucht. Fuer das Kriterium N1=Lymphknoten (LK)>1 cm betrug die Sensitivitaet 47%. Fuer N1=LK>1 cm/vermehrte Anzahl LK<1 cm war sie 71%, bei erkennbarem Primaertumor sogar 87%. Unter Beruecksichtigung der derzeit geltenden operativen Therapiekonzepte ist der Nachweis von regionaeren Lymphknotenmetastasen nur bei Rektumkarzinom bzw. fuer Kolonpolypen oder fuer lokal exzidierte Karzinome fuer das therapeutische Vorgehen relevant. In diesen Faellen leistet die CT mit den erweiterten Kriterien fuer ein N1-Stadium trotz hoeherer falsch-positiver Raten eine wertvolle Hilfestellung fuer die Entscheidung ueber eine neoadjuvante Bestrahlung oder eine Nachresektion.

    High alloyed superaustenitic steels and NiCrMo alloys are recommended in consequence of the results of extensive laboratory corrosion experiments under the strong corrosive conditions with up to 360 g chloride content at temperatures up to 85 C. Because results of laboratory corrosion tests are only of limited relevance to the behaviour in practice, field tests were carried out with immersion of welded materials and of heat exchanger tubes under operating conditions of an evaporation plant for waste water from flue gas desulphurization of a coal-fired power plant. Different kinds of high alloy superaustenitic steels and NiCrMo alloys were studied as TIG-welded specimens in immersion tests. (orig.) [German] Hochlegierte Sonderedelstaehle und NiCrMo-Legierungen empfehlen sich aufgrund der Ergebnisse umfassender Laboruntersuchungen unter den stark korrosiven Bedingungen fuer Eindampfanlagen fuer Abwasser aus der Nassreinigung von Rauchgasen von Grossfeuerungsanlagen mit bis zu 360 g/l Chloridgehalt und Temperaturen bis zu 85 C. Weil aber Ergebnisse von Laborpruefungen nur begrenzte Aussagefaehigkeit fuer das Verhalten unter Praxisbedingungen haben, wurden Feldversuche mit der Auslagerung geschweisster Werkstoffe und von Waermetauscherrohren unter Betriebsbedingungen einer Eindampfanlage fuer Abwasser aus der Rauchgasentschwefelung eines kohlebefeuerten Kraftwerks durchgefuehrt.

    A comparison of the measured and simulated values of three collector types shows that evacuated tube collectors are superior to transparent-insulation flat collectors in the case of high-temperature uses. At temperatures of 150 C and above good results were obtained using evacuated tube collectors with compound parabolic concentrators manufactured by Microtherm. CORTEC collectors are suited for temperatures in the range of 100 C to 150 C provided that the surface ratio is irrelevant. Costs play a decisive role when selecting systems. The results obtained show that improved transparent-insulation flat collectors can compete with evacuated tube collectors in the 100 C to 150 C temperature range. (orig.) [Deutsch] Ein Vergleich der gemessenen und simulierten Werte der drei Kollektoren zeigt, dass die Vakuumroehrenkollektoren fuer den Einsatz in Hochtemperaturanwendungen dem mit transparenter Waermedaemmung isolierten Flachkollektor ueberlegen sind. Der Vakuumroehrenkollektor mit CPC von Microtherm erzielt gute Resultate ab 150 C und mehr. Wogegen der CORTEC-Kollektor fuer den Einsatz im Temperaturbereich zwischen 100 C und 150 C geeignet ist, solange das Flaechenverhaeltnis keine Rolle spielt. Wie fuer die meisten Anwendungen spielen die Kosten eine entscheidende Rolle fuer die Wahl des eingesetzten Systems. Die Resultate zeigen, dass ein verbesserter mit TWD ausgeruesteter Flachkollektor im Temperaturbereich von 100 C bis 150 C konkurrenzfaehig zu Vakuumroehrenkollektoren sein kann. (orig.)

Operation comfort doesn't give an inessential contribution to a reliable and appropriate interaction between driver and vehicle that means also a contribution to a reliable function of the total system and thereby to safety. Therefore the subjective experience of assistance systems is of excellent importance with view on the subjective and public confidence in new assistance systems. Are they seen rather as a gain of comfort, as it is preferred by the producer by reasons of production related liability, or as an easing of the driver's behaviour providing safety? Consists in the last called tendency a new kind of danger? In this connection juristic problems may not be unmentioned. The driver may not or not completely be called to account for procedures on which he has no influence or thinks to have no influence. In this case the account for the not compensated damage is contributed to the producer of the system. Therefore, by considering human characteristics and abilities of the driver during the development of assistance systems unwanted juristic consequences should be prevented. (orig.)

    The ecological impact of six different disposal routes for sewage sludge of a major sewage treatment plant (three options for agricultural use in liquid, dried and limetreated form, and three options of incineration in a mono-sewage sludge incineration plant, a cement factory and a `Schwel-Brenn` type incinerator for municipal solid waste) has been studied with an comprehensive inventory and five impact assessment methods. Three methods show the important role of soil pollution. Existing methods are not yet able to consider all the factors necessary. The inventories should be completed concerning natural phosphorus resources and organic micropollutants. (orig.) [Deutsch] Sechs Entsorgungsvarianten (drei betreffen die landwirtschaftliche Verwendung in fluessiger, thermisch getrockneter und gekalkter Form und drei die Verbrennung in einer Schlammverbrennungsanlage, einem Zementofen und einer Schwel-Brenn-Anlage fuer Kehricht) fuer den Klaerschlamm einer grossen ARA werden mittels Inventarisierung der verursachten Umweltbelastung und fuenf Bewertungsmethoden untersucht.

    2000-07-01

    Modern recording systems form the basis for competitive services. They are, however, only successful when integrated precisely into a lean running organization. By means of practical examples the necessity to place great emphasis on the costs of a system besides the investment costs when deciding about a recording system, will be examined. The significant changes on the energy market and the increasing demand of the housing economy for a comprehensive offer of services from the supply industry are main initiators for a whole new line of businesses on the supply economy sector. The great challenge for the supply industry lies in the task to install lean and effective system which are on one hand reliable and easy to handle for the whole duration of the contract and on the other hand are so cost efficient, that an adequate profitability can be ensured (see also: 'The secret winners', Zfk October 1999). A decisive factor for this reason is the metering technology, which has to ensure for the whole duration of the contract that correct consumption values are registered, on the basis of which as fast and punctual as possible a legally safe invoicing can be prepared. (orig.) [German] Moderne Erfassungssysteme bilden die Grundlage fuer wettbewerbsfaehige Dienstleistungen, die jedoch erst bei sauberer Einbindung in eine schlanke Ablauforganisation erfolgreich sind. Anhand von Praxisbeispielen wird die Notwendigkeit betrachtet, bei der Entscheidung fuer ein Erfassungssystem neben den Investitionskosten den Systemkosten entscheidendes Gewicht zu verleihen.

    1998-11-01

    At present, selection of procedures for inservice inspection has to take into account the legal basis, i.e. the existing regulatory codes, and the practical aspects, i.e. experience and information obtained by the general, initial inservice inspection or performance data obtained by the latest, recurrent inspection. However, regulatory codes are being reviewed to a certain extent in order to permit integration of technological progress. Depending on the degree of availability in future, of inspection task-specific, sensitive and qualified NDE techniques for inservice inspections (`risk based ISI`), the framework of defined inspection intervals, sites, and detection limits will be broken up and altered in response to progress made. This opens up new opportunities for an optimization of inservice inspections for proof of component integrity. (orig./CB) [Deutsch] Zur Zeit muss sich die Auswahl der Pruefverfahren an den gueltigen Regelwerken und, da es sich um wiederkehrende Pruefungen handelt, an der Basispruefung bzw. der letzten wiederkehrenden Pruefung orientieren. Jedoch vollzieht sich zur Zeit eine Oeffnung der Regelwerke, mit der man auch der Weiterentwicklung der Prueftechniken Rechnung traegt. In dem Masse, wie zukuenftig auf die Pruefaufgabe/Pruefaussage optimal abgestimmte und qualifizierte Prueftechniken mit einer hohen Nachweisempfindlichkeit am Bauteil fuer zielgerichtete wiederkehrende Pruefungen (als `risk based ISI`) zur Verfuegung stehen, wird der Rahmen mit festgelegten Pruefintervallen, Prueforten und festen Registriergrenzen gesprengt und variabel gestaltet werden koennen. Damit ergeben sich neue Moeglichkeiten fuer eine Optimierung der WKP zum Nachweis der Integritaet des Bauteils. (orig./MM)

    Tools and wear parts for compacting tools are subjected to high abrasive wear and mechanical loading at elevated temperatures. MMC's based in iron- or nickel with hard particles are developed and investigated. The materials were manufactured from powders by hot isostatic pressing (HIP) and subsequently heat treated. Diffusion between hard phases and metal matrix brings about certain micro structures which were tested with respect to the resistance against sliding abrasion at room and elevated temperatures. Three-point bending tests and thermal cycling of the material was utilized to characterise the mechanical behaviour. Based on this results a toolkit for a roller press for briquetting was produced and brought into application. (orig.) [German] Werkzeuge und Verschleissteile fuer die Verarbeitung von mineralischen Guetern bei erhoehter Temperatur unterliegen sowohl hohem abrasivem Verschleiss als auch hohen mechanischen Lasten. Es werden hartphasenhaltige Verbundwerkstoffe auf Eisen- und Nickelbasis entwickelt und untersucht. Die Fertigung dieser MMC's erfolgt durch heiss isostatisches Pressen (HIP) und anschliessende Waermebehandlung. Durch Diffusion zwischen Hartphasen und Metallmatrix entstehen Gefuege, die bezueglich ihres Widerstandes gegen Abrasivverschleiss bei Raumtemperatur und gegen Korngleitverschliess bei erhoehter Temperatur geprueft werden. Zur Charakterisierung der mechanischen Eigeschaften werden Dreipunktbiegeversuche und thermsiche Ermuedungsversuche durchgefuehrt. Die gewonnenen Erkenntnisse werden genutzt, um einen Werkzeugsatz fuer eine Brikettierpresse herzustellen und in Einsatz zu bringen. (orig.)

    The Forest State Report 2012 systematically records the health status of the forest resources in the country on a scientific basis. Environmental information is measured, recorded and evaluated in the context of forest environmental monitoring using a measuring network. More than a third of the forest area has suffered significant damage. The share of undamaged forest areas has declined by almost one third to 26 percent since last year. Compared to the previous year, the crown damage increased by an average of 2.5 percentage points. More important, however, is the fact that for the two main tree species spruce and beech since the turn of the millennium, there has been a marked increase in the damage intensity for all age groups. [German] Der Waldzustandsbericht 2012 erfasst auf wissenschaftlicher Basis systematisch den Gesundheitszustand der Waldbestaende im Land. Im Rahmen des Forstlichen Umweltmonitorings werden mit Hilfe eines Messnetzes Umweltinformationen gemessen, erfasst und ausgewertet. Ueber ein Drittel der Waldflaeche weist deutliche Schaeden auf. Der Anteil der ungeschaedigten Waldflaechen ist seit dem letzten Jahr um fast ein Drittel auf 26 Prozent zurueckgegangen. Die Kronenschaeden haben gegenueber dem Vorjahr um durchschnittlich 2,5 Prozentpunkte zugenommen. Wichtiger ist jedoch der Befund, dass fuer die beiden Hauptbaumarten Fichte und Buche seit der Jahrtausendwende ein deutlicher Anstieg der Schadensintensitaet fuer alle Altersklassen zu beobachten ist.

    In Baden-Wuerttemberg, the state of forests has been recorded since the 1980s in the course of an annual forest status report. In 2015, a decline in forest damage can be reported. As an indicator for the evaluation of the forest state, the crown condition of the trees applies. The average crown defoliation has been reduced by two percentage points to around 24 percent, while the share of healthy forest areas increased by five percentage points to a total of 29 percent. The clearly damaged forest areas decreased by six percentage points to 36 percent. Concerns are causing a relatively new fungus disease in the tree species ash, the ash dieback. [German] In Baden-Wuerttemberg wird der Zustand der Waelder seit den 1980er Jahren im Zuge eines jaehrlichen Waldzustandsberichtes erfasst. Fuer das Jahr 2015 kann erfreulicherweise einen Rueckgang der Waldschaeden verzeichnet werden. Als Indikator fuer die Beurteilung des Waldzustandes gilt der Kronenzustand der Baeume. Die durchschnittliche Kronenverlichtung hat sich um zwei Prozentpunkte auf rund 24 Prozent verringert, waehrend sich der Anteil der gesunden Waldflaeche um fuenf Prozentpunkte auf insgesamt 29 Prozent erhoehte. Die deutlich geschaedigten Waldflaechen verringerten sich um sechs Prozentpunkte auf 36 Prozent. Sorgen bereitet eine relativ neue Pilzerkrankung bei der Baumart Esche, das Eschentriebsterben.

    One of the aims of environmental research at the GSF Research Centre for the Environment and Health is to determine the behaviour of environmentally consequential chemicals in terrestrial ecosystems under as natural conditions as possible. The GSF lysimeter plant in Neuherberg permits studying the environmental behaviour of organic chemicals in different soils. Collaborators at GSF have developed a means of applying -14-marked substances in field lysimeters so as to be able to refind released chemicals, identify their conversion products and set up mass balances for the chemicals.

    Recent years have been shaped by the introduction of programme-oriented funding. In 2004, we were able once again to focus on the real goal of the GSF, the performance of excellent research. The effects of fine particles, for example, are at the centre of public interest. This topic is not only of great importance for health, it also has a wide-reaching economic significance; we have only to think of filters for diesel engines. The GSF was involved in many scientific successes. For example, the results on the economic costs of smoking received considerable attention from both the general public and the scientific world. GSF scientists were involved in the decoding of the chicken genome and the discovery of a Parkinson gene. Together with university and other research organisations, they founded a Virtual Institute on Biotic Interactions, and took part in an international project on the development of combination vaccines against HIV. The setting up of the GSF 'glass laboratory', which was created with substantial support form the Helmholtz Association, is particularly worthy of mention. GSF scientists have been awarded various prizes, for example the Felix Wankel Prize awarded to Professor Jean-Marie Buerstedde. The Bavarian Advancement of Women Prize 2004, which distinguished exemplary initiatives in the area of family and women's advancement, was a special honour. Professor Magdalena Goetz was appointed Director of the Institute for Stem Cell Research. (orig.)

  13. Communicating to gain public acceptance of energy projects; Akzeptanzkommunikation fuer Energieprojekte

    Whoever plans to execute energy projects in today's world should be aware of the fact that the social framework conditions surrounding such projects have changed significantly. For the organization executing the project to merely adhere to the legally prescribed authorization procedure and leave it until the end of the planning procedure to inform those affected is often no longer sufficient for gaining public acceptance. Large parts of the population criticise the usual procedures because they have lost confidence in this kind of decision making, which offers them too little scope for co-determination. Thus for some years there has been a growing number of cases where citizens demand full public participation and early information on why the project in question is needed and what kinds of impact it will have. Lack of acceptance can lead to resistance, with negative effects on the project and the companies involved. TECSOL takes care of the communication management alongside energy projects, taking its bearings by the existing standards for voluntary early information of the public, as recommended by the VDI (Guideline 7001) and required by the legislature (PlVereinhG = Law for Improvement of Public Participation and Harmonisation of Plan Approval Procedures). The lecture outlines the societal challenges involved as well as the possibilities for dealing fairly with demands of the population in the context of energy projects. This is illustrated using the model case of the ''Etzel cultural landscape'' as a practical example, in which TECSOL played a prominent role on behalf of IVG Caverns GmbH. [German] Wer heute Energieprojekte umsetzen will, muss sich im Klaren darueber sein, dass sich die gesellschaftlichen Rahmenbedingungen stark veraendert haben.

    Institutions and institutional theory are important topics in contemporary economic theory. However, their application to issues of environmental economics still is in its infancy. The book summarizes the state of the art in research on institutional aspects of environmental economics, as seen from the angle of the economic and social sciences, and outlines a variety of perceivable approaches oriented towards integrating the institutional aspects in environmental economic theory. This process eventually leading to broader consideration of implementation problems, enforcement and organisational aspects, legal aspects or market factors and functions influencing environmental policy, theory and practice of environmental policy are expected to draw near to each other and thus create the long-hoped-for chance to commence a true interdisciplinary dialogue about the entire spectrum of environmental issues.

    Details are given about radioactive waste management and radioactive waste management fundamentals as well as about the respective methods applied by the Baden-Wuerttemberg radioacive waste depot. The waste treatment, quality assurance and internal inspection methods applied by Hauptabteilung Dekontaminationsbetriebe (HDB), Kernforschungszentrum Karlsruhe (KfK) are described, and recommendations are given for the establishment of regional depots in the new provinces of the Federal Republic of Germany. These recommendations which are based on Western German standards before unification suggest regional depots with combined administrative systems which watch over the depot use and charges, the foundation of a waste management association responsible for the disposal, transport, intermediate storage and conditioning of radioactive wastes in the new provinces, and the establishment of a facility to be run by the proposed waste management association for the intermediate storage of conditioned waste packages intended for final disposal.

    The Linac Coherent Light Source-II project represents the expansion of the LCLS free-electron laser, which has been successfully operated at the SLAC National Accelerator Laboratory since 2009. In collaboration with several national institutes, 37 cryomodules with superconducting accelerator cavities will be installed in a 700 m long section of the existing tunnel. The use of superconducting accelerator technology will enable particle energy of up to 4 GeV in CW (continuous wave) operation. Two identical cryogenic systems with an equivalent output of 18 kW each at 4.5 K are described below. The plants supply the linear accelerator with helium at several temperature levels. Superfluid helium II provides the cooling necessary to maintain superconductivity in the cavities. The operating temperature of the 1.3 GHz cavities has been set at 2 K. Two further helium circuits are used for shield cooling at approx. 35 K and cooling of heat loads at 5 K level. The purely dynamic compression of the cold helium vapour is a technical feature of the systems described here. In a five-stage chain of cold compressors of 32 mbar at the cavities, it is absolutely compressed to the suction pressure of the circulation compressors at approx. 1 bar.

    Solar energy will surely continue to be the most important renewable energy source. Since 1985, solar cell production has doubled every five years while the per unit price decreased continuously. This trend is expected to continue. Germany made important contributions both in the construction of new solar cell production plants and in the development of new PV materials and material combinations, as well as in technology and PV plant construction. The states of Thuringia and Saxony were significant contributors. In Thuringia, two solar cell production plants were constructed, while Saxon vacuum coating technology was used in nearly all new German production plants. This workshop presented the activities in Thuringia in Saxony. Contacts were to be established between partners from industry and research, joint projects were to be initiated, and society and politicians were to be informed on the success and new chances achieved. The workshop was held on the occasion of the termination of construction and the starting of experimental production of the ANTEC Solar GmbH factory at Rudisleben. [German] Im Mix der erneuerbaren Energien spielt die Solarenergie kuenftig wohl die wichtigste Rolle. Seit 1985 verdoppelt sich die Solarzellenproduktion in jeweils fuenf Jahren, gleichzeitig sank der Preis pro Leistungseinheit kontinuierlich. Dieser Trend wird weiter anhalten. Deutschland leistete in den letzten Jahren wichtige Beitraege zu dieser Entwicklung, sowohl beim Aufbau neuer Fertigungskapazitaeten fuer Solarzellen, als auch bei der Entwicklung neuer Photovoltaik-Materialien bzw. -Materialkombinationen und auf den Gebieten der Technologie und des Anlagenbaus. Der Anteil Thueringens und Sachsens an dieser positiven Entwicklung ist groesser als generell vermutet. In Thueringen entstanden zwei Unternehmen fuer die Solarzellenproduktion, der saechsische Vakuumbeschichtungs-Anlagenbau war am Aufbau fast aller neuen deutschen Fertigungsstaetten beteiligt.

    On March 13,.2013 the Federal Office of Radiation Protection (BfS) published a note that the responsible group of the Helmholtz Zentrums Muenchen had finished the experiments in the socalled leaching test room at the 490 m level of the Asse II mine. In this room, the previous operator the Gesellschaft fuer Strahlen- und Umweltforschung mbH (GSF) carried out leaching and corrosion experiments with cemented full-scale samples. These experiments were performed since 1979 requested by the licensing authorities. With respect to the safety case for the Asse salt mine it was a need to demonstrate the transferability of results obtained by laboratory samples to real waste forms and to investigate the effects of the industrial cementation process an the properties of the waste forms. A research program was initiated by the Nuclear Research Centre Karlsruhe (today Karlsruhe Institute of Technology, KIT) and the Institut fuer Tieflagerung of the Gesellschaft fuer Strahlenforschung m.b.H. (GSF). Since 1996 the scientific supervision of the experiments were dedicated to the Institute for Nuclear Waste Disposal (INE) of KIT. Until 2013, the corroding solutions were sampled several times. In 2006 four full-scale samples were retrieved and investigated with respect to variations of the solids. After termination of the experiments in January 2013, radioactively doped samples were transferred to KIT-INE for final evaluations. The present report summarizes the background and objectives of the experiments as well as the results of the solutions and solid state analyses.

    Energy supply companies (resellers) and electric utilities as traders in the liberalized markets increasingly focus their activities on their core businesses and offer their capabilites also in other branches of industry, thus achieving synergistic effects. The evolution of e-commerce in the energy supply sector in Germany is described in this article, and recommendations are given to companies as to suitable change management strategies for successful marketing and procurement via the world wide web, using IP technologies as a basis for transactions. (CB) [German] Energieversorgungsunternehmen (EVU) besinnen sich auf ihre Kernkompetenzen, bieten diese auch in anderen Branchen an und erzielen damit Synergieeffekte. Ein weiterer Aspekt ist die zunehmende Vernetzung der europaeischen Stromnetze. Die Konvergenz der Maerkte wird ferner durch den Einsatz von IP(Internet-Protokoll)-Technologien vorangetrieben, da das Internet eine Informations- und Transaktionsplattform fuer saemtliche Marktteilnehmer schafft. Welche diesbezueglichen Transformationsstrategien von den EVU bereits heute zu ergreifen sind, wird anschaulich aus einem hierzu entwickelten Modell abgeleitet. (orig./CB)

    Within a joint project supported by the Free State Saxony a novel bearing and transport system was developed. The prototype is based on the combination of the magnetic bearing technique using high temperature-superconductors with a non-contacting linear drive. This non-contracting 'lift' is free from friction and contaminations due to wear and therefore predestinated for applications in clean rooms, e.g. in the microelectronic technology. (orig.) [German] Im Rahmen eines Verbundprojektes, gefoerdert vom Freistaat Sachsen, wurde ein neuartiges Lager- und Transportsystem in Form einer Kombination der supraleitenden Magnetlagertechnik mit Hochtemperatursupraleitern und einem beruehrungslos arbeitenden Linearantriebssystem am Beispiel eines Demonstrators entwickelt. Der voellig beruehrungslos und damit reibungs- und abriebfrei funktionierende Lift ist fuer Anwendungen in Reinraeumen z.B. in der Mikroelektroniktechnologie praedestiniert. (orig.)

    The explanations, which have been given in the talk are supposed to reveal, that the aim of the marketing for electric-powered vehicles is not to carry the idea of environmental protection into the society. It is far more important to use the power of the present environmental consciousness in order to guarantee the consumers demands for mobility, taking into consideration the ecological interests. (orig.)

    Reducing the noise level in the interior of vehicles is both a comfort necessity and a challenging technical task. Reliable identification of the accessories responsible for high or low engine-noise levels in the interior of cars classically requires costly, time-consuming, extensive measurement sessions. Artificial intelligence tools efficiently solve the mentioned system-identification problem, and provide a principled way of extracting the information of interest from reduced size databases.

    Against the background of climate change and ever-rising commodity prices, the simultaneous reduction of fuel consumption and exhaust emissions is the focus of modern research and development work in the field of internal combustion engines. In this context homogeneous Low-Temperature Combustion (LTC) is regarded as one of the most promising concepts to overcome the conflict of goals between high efficiencies and low emissions. In collaboration with MTU Friedrichshafen a new LTC combustion system which is characterised by least emissions, reasonable low fuel consumption and acceptable mechanical engine stress has been developed at the Institut fuer Kolbenmaschinen of the Karlsruhe Institute of Technology.

First ideas about standard demands, technical solutions and multi-functional design showed that the project had to be handled in such a flexible way that temperature controlling (for the transportation of deep-frozen goods, temperature-controlled DANZAS-warehouses and all future temperature-controlled transportation) and the monitoring of security-relevant transportation can be integrated in one and the same project. (orig.)

    The article explains to what extent suitable measures can be realized and supported in a municipality with municipal energy concepts or even climate protection concepts. The target is to attain with limited financial means the most favourable economic and ecological effects in the municipality or in the region. Many electric utilities have in the last years forced the realization of energy conservation measures and have become energy service companies. With their expert knowledge they are ideal partners for politics, public adminstration and citizens. They have the best qualificatons for the development and realization of municipal concepts. In many cases it shows that with detailed studies the target can be quicker and more effectively attained as with extensive, time-consuming and expensive studies which are not particularly realization-oriented. The report is to give examples which might be helpful for the development of a concept. (orig./UA) [Deutsch] Der Beitrag erlaeutert, inwieweit umfangreiche kommunale Energiekonzepte oder sogar Klimaschutzkonzepte geeignete Massnahmen in der Kommune realisieren und foerdern koennen. Ziel sollte sein, mit begrenztem Mitteleinsatz die oekonomisch-oekologisch groessten Effekte in der Kommune bzw. in der Region zu erzielen. Viele Energie-Versorgungsunternehmen haben in den letzten Jahren die Realisierung von Energieparmassnahmen vorangetrieben und sich zu Energie-Dienstleistungsunternehmen entwickelt. Mit ihrer Sachkompetenz sind sie der ideale Partner fuer Politik, oeffentliche Verwaltung und Buerger/innen. Sie bringen die besten Voraussetzungen mit bei der Erarbeitung und Umsetzung von kommunalen Konzepten. Vielfach zeigt sich, dass Detailkonzepte schneller und wirkungsvoller zum Ziel fuehren, als umfachreiche, zeitaufwendige und teure Studien, die wenig umsetzungsorientiert sind. Die nachfolgenden Ausfuehrungen sind als Beispiele gedacht. Sie koennen Anregungen fuer die Erstellung eines Konzeptes vermitteln. (orig./UA)

    The value of macromolecular contrast agents (MMCM) for the characterization of benign and malignant breast tumors will be demonstrated in this review. Animal studies suggest a high potential of MMCM to increase the specificity of MR-mammography. The concept of tumor differentiation is based on the pathological hyperpermeability of microvessels in malignant tumors. MMCM show a leak into the interstitium of carcinomas, whereas they are confined to the intravascular space in benign tumors. Capabilities and limitations of the MMCM-prototype. Albumin-Gd-DTPA, for breast tumor characterization will be summarized and compared to the standard low molecular weight contrast agent Gd-DTPA. Initial experience with new MMCM, such as Dendrimers, Gd-DTPA-Polylysine and MS-325 will be outlined. The potential of `blood-pool`-iron oxides, such as AMI-227 for the evaluation of tumor microvascular permeabilities will be discussed. (orig.) [Deutsch] Diese Uebersicht stellt den Stellenwert makromolekularer Kontrastmittel (MMKM) fuer die MR-tomographische Charakterisierung von benignen und malignen Mammatumoren dar. Aufgrund experimenteller Studien lassen MMKM eine signifikante Verbesserung der Spezifitaet der dynamischen kontrastmittelunterstuetzten MR-Mammographie erwarten. Das differentialdiagnostische Konzept beruht auf der pathologischen Hyperpermeabilitaet von Kapillaren in Karzinomen, die einen MMKM-Austritt in das Tumorinterstitium bedingt, waehrend die intakten Kapillaren benigner Tumoren nicht permeabel fuer MMKM sind. Diagnostische Moeglichkeiten und Grenzen des MMKM-Prototyps, Albumin-Gd-DTPA (92 kD), werden dargestellt und mit dem niedermolekularen Standard-Kontrastmittel Gd-DTPA (500 D) verglichen.

    Principal Correlation Pattern Analysis (PCPA) maps the local circulation, temperature and precipitation anomalies in the northern hemisphere in monthly resolution and permits an interpretation of their causes. Calculations are made for the El Nino phenomenon, NAO, and the quasi-11-year cycle of solar radiation variation. Especially the El Nino calculations show the efficiency of PCPA. [German] Mit Hilfe der Principal Correlation Pattern Analysis (PCPA) koennen die von verschiedenen Klimaantrieben erzeugten lokalen Zirkulations-, Temperatur- und Niederschlagsanomalien auf der Nordhemisphaere in monatlicher Aufloesung dargestellt und ursaechlich interpretiert werden. Diese Rechnungen wurden fuer das El Nino Phaenomen, die NAO und den quasi 11-jaehrigen Zyklus der solaren Strahlungsschwankungen durchgefuehrt. Insbesondere die Untersuchungen zu Wirkungen von El Nino auf Europa zeigen, dass die PCPA die Kopplungen eines Prozesses mit dem Klimasystem sehr genau beschreibt und somit die Voraussetzungen schafft, die Wirkungen dieses Klimaantriebs zu modellieren und ihn zur Vorhersage zu nutzen. Erste einfache Vorhersageexperimente fuer das europaeische Klima bestaetigen diese Aussage. (orig.)

Further adjustment of the parameterizations seems to be necessary. Other components of the climate system have to be considered to successfully describe the complex feedbacks and processes of the climate subsystems. (orig.) [German] Die Arktis und der subpolare Nordatlantik bilden mit ihren komplexen Mechanismen und Rueckkopplungen eine wichtige Komponente unseres Klimasystems. Aufgrund der geringen Beobachtungsdichte und der niedrigen Aufloesung globaler Klimamodelle, bietet sich der Einsatz hoeher aufloesender regionaler Klimamodelle an. Das hier verwendete regionale Klimamodell (REMO) basiert auf dem frueheren Wettervorhersagemodell EM des Deutschen Wetterdienstes (DWD) und wurde am Max-Planck-Institut fuer Meteorologie (MPIfM) in Hamburg weiterentwickelt. Fuer die Simulation subskaliger Prozesse stehen zwei Saetze physikalischer Parametrisierungen zur Verfuegung - die urspruenglich verwendete DWD-Physik und die ECHAM4-Physik des MPIfM. Der dynamische Teil ist in beiden Faellen identisch. REMO wird zunaechst an das neue Untersuchungsgebiet angepasst. Die neue Konfiguration beruecksichtigt bei einer horizontalen Aufloesung von 0.5 x 0.5 und 145 x 121 Glitterpunkten die gesamte Arktis und den Nordatlantik bis etwa 40 N. Mit DWD- und ECHAM4-Physik im Vorhersage- und Klima-Mode werden unterschiedliche Zeitraeume simuliert. Als Antriebsdaten werden die NCEP/NCAR-Reanalysen mit einer zeitlichen Aufloesung von 6 Stunden verwendet. Da REMO bisher nur in gemaessigtem Klima eingesetzt wurde, steht der Test des Modells unter den extremen Bedingungen der hohen Breiten im Vordergrund. Beim Vergleich mit Schiffsbeobachtungen aus der Labrador-See liegt REMO deutlich dichter an den Messungen als die Antriebsdaten. Unrealistisch hohe Feuchten in den Reanalysen sind vermutlich die Ursache erhoehter

    The continuing rise in cost pressure calls for measures for enhancing the efficiency of operation management and maintenance. At the same time it is necessary to maintain the requisite reliability of production and keep abreast of the ever more stringent requirements of working safety and environment protection. This paper presents an integral operation management system for production plants which does justice to both the productive and the and the conserving function of operation management. The development and introduction of this system to conventional power plants has meanwhile begun. The system consistently gives consideration to the fact that operation management depends on processing data and information of different properties. Whereas process data can show strong fluctuations, there are many kinds of information on the plant concerning, for example, plant installations, processes, damage, and maintenance which hardly fluctuate at all or only change over long time periods. These latter include plant and installation addresses, technical data on the system or on maintenance. In operation management systems designed for production plants it can therefore be useful to organise the handling of process data (dynamic data) and plant data (static data) separately.

Fuer konventionelle Kraftwerke wurde die Entwicklung und Einfuehrung begonnen. Dieses System beruecksichtigt konsequent, dass bei der Betriebsfuehrung Daten und Informationen mit unterschiedlichen Eigenschaften zu verarbeiten sind.

    Knittings based on ceramic filament yarns can be used to clean polluted air and exhaust gas efficiently up to temperatures of 1000 C. They provide interesting properties for the filtration of Diesel particles as well as for catalysis and adsorption of toxic gas components. The special knitting technology can handle any brittle fibers, producing elastic structures, which are thermochoc-resistent and can therefore even be used for preturbo applications. The first part of this paper, published in MTZ 56 (1995) 2 deals with the basic properties of this cleaning medium. This second part concentrates on Diesel particulate trop applications. These new trap and catalyst concepts are under development by Buck/Bondorf with TTM/Niederrohrdorf. Basic research is delegated to ETH Zuerich and Universitaet by Gillet/Edenkoben and, with focus on preturbo-applications by MTU/Friedrichshafen. (orig.) [Deutsch] Gestricke aus keramischen Endlosfasern sind bis zu Temperaturen um 1000 C fuer die Abluft- und Abgasreinigung einsetzbar. Sie eignen sich fuer die Filtration von Dieselpartikeln, insbesondere deren Feinstfraktionen ebenso wie fuer die Katalyse und fuer die Adsorption gasfoermiger Schadstoffkomponenten. Die Strukturen sind volumenelastisch, unempfindlich gegen Thermoschock und daher auch im motornahen Bereich risikoarm einsetzbar. In einem ersten Teilbeitrag in der Februarausgabe der MTZ wurden grundlegende Erkenntnisse dieses Abgasreinigungsmediums beschrieben.

    Lead has always been an important metal in plain bearing technology. Completely lead-free solutions for high-end engine applications are still not considered to be technically achievable. Therefore, the European End of Life Directive (2000/53/EC), which took effect on 1 July 2003, lists copper-based lead/bronze bearings as an exception. The bearing group of Federal-Mogul has now announced its exit from the lead industry and addresses the issue layer by layer. A recently introduced adaptive bearing offers a lead-free overplate for high-performance internal combustion engine applications. This new bearing changes its technical characteristics during the running-in phase. (orig.) [German] Blei war schon immer eine wichtige Komponente in der Gleitlagertechnik. Bis heute gelten vollstaendig bleifreie Loesungen fuer hochbelastete Gleitlager als technisch nicht machbar. Deshalb nennt die europaeische Altautoverordnung (2000/53/EG), die seit dem 1. Juli 2003 in Kraft ist, als Ausnahme die kupferbasierten Bleibronzelager. Die Gleitlagergruppe von Federal-Mogul hat jetzt ihren Rueckzug aus der Verarbeitung von Blei angekuendigt und geht das Thema Schicht fuer Schicht an. Ein kuerzlich eingefuehrtes, anpassungsfaehiges Lager fuer High-End-Verbrennungsmotoren verfuegt ueber eine bleifreie Laufschicht. Bei diesem neuen Lager veraendern sich die technischen Eigenschaften waehrend der Einlaufphase. (orig.)

    The renaissance of carbon dioxide in refrigeration engineering is impressive. The contribution shows that the disadvantages of this refrigerating fluid can be compensated by modifying the refrigeration circuit. A combined expander-compressor working by the free piston principle and developed at Dresden Technical University is described. [German] Kohlendioxid erlebt im Bereich der Kaeltetechnik infolge der schwierigen Suche nach umweltvertraeglichen Ersatzkaeltemitteln fuer die Fluorchlorkohlenwasserstoffe eine beeindruckende Renaissance. Es soll anhand thermodynamischer Prozessberechnungen gezeigt werden, dass durch die Modifikation des Kreisprozesses unter Beachtung der besonderen thermodynamischen Eigenschaften des Kohlendioxids diese Nachteile bereits bei der theoretischen Leistungszahl ausgeglichen werden koennen. Dafuer wird das Kohlendioxid in einem Prozess mit zweistufiger Verdichtung arbeitsleistend entspannt. Die Besonderheit dieses Prozesses ist die Verwendung einer speziell fuer diesen Anwendungsfall entwickelten Maschine, die die gewonnene Expansionsarbeit direkt fuer die Verdichtung des Kohlendioxids in der zweiten Verdichtungsstufe nutzt. Es handelt sich dabei um eine nach dem Freikolbenprinzip arbeitende Expansions-Kompressions-Maschine, die an der TU Dresden entwickelt und gegenwaertig getestet wird. (orig.)

    The work concerns the task of control described as dispatching of extensive energy supply and distribution networks. Due to the special contractual situation, there are special long-term targets in firms, which must be achieved in addition to the extensive operational tasks of control and monitoring of the networks. The concepts introduced in the work offer a framework for a target-orientated design of computer-aided menus for this superior process control in the energy industry. (orig./GL) [Deutsch] Die Arbeit betrachtet die als Dispatching bezeichnete Aufgabe der Fuehrung ausgedehnter Energieversorgungs- und verteilungsnetze. Aus den speziellen Vertragssituationen ergeben sich in den Unternehmen besondere, langfristige Zielvorgaben an die mit der Betriebsfuehrung beauftragen Operateure, die zusaetzlich zu den umfangreichen operativen Aufgaben der Fuehrung und Ueberwachung der Netze zu erreichen sind. Die in der Arbeit vorgestellten Konzepte bieten den Rahmen fuer einen zielgerichteten Entwurf rechnergestuetzter Hilfsmittel fuer diese uebergeordnete Prozessfuehrung in der Energiewirtschaft. Das erstellte Gesamtsystem wird abschliessend zur Loesung einer konkreten, energiewirtschaftlichen Problemstellung eingesetzt. Die entwickelte Anwendungsloesung wird als Hilfsmittel fuer die technische und vertragliche Optimierung im Dispatching eingesetzt.

    The report presents a summary of the project of the above title (EFAS project). While earlier projects focused on the technical side, EFAS is the first to present a systematic analysis, presentation and evaluation of the parameters influencing driving support systems. With the aid of a systemic analysis, the key influencing factors are defined and analyzed, and three scenarios are developed which take account of user-oriented, organizational, operational, technical, infrastructural and legal aspects. The scenarios are evaluated with the aid of driving and traffic simulations in the fields of humans, organization and technology, and actions are recommended on this basis for driving support systems in cargo transport. [German] Der Bericht fasst die Ergebnisse des Projektes ''Einsatzszenarien fuer Fahrerassistenzsysteme im Gueterverkehr'' (EFAS) zusammen. Bisher wurde die Thematik Fahrerassistenzsysteme hauptsaechlich auf der Seite der Fahrzeugtechnik vorangetrieben. Das Projekt EFAS stellt nun zum ersten Mal eine umfassende Analyse, Darstellung und Bewertung dar. Mit Hilfe einer systemischen Analyse werden die wesentlichen Einflussfaktoren fuer die Einbindung von Fahrerassistenzsystemen in das Gesamtsystem ''Verkehr'' bestimmt und untersucht. Hieraus werden drei Einsatzszenarien entwickelt, die nutzerbezogene, organisatorische, betriebliche, fahrzeugtechnische, infrastukturelle und rechtliche Aspekte zu Zukunftsbildern zusammenfuegen. Die Szenarien werden mit Hilfe von Fahr- und Verkehrssimulationen in den Bereichen Mensch, Organisation und Technik bewertet. Aus den Ergebnissen werden konkrete Handlungsempfehlungen fuer den Einsatz von Fahrerassistenzsystemen im Strassengueterverkehr abgeleitet. (orig.)

    Eye tumors (choroidal melanomas, iris melanomas, and choroidal hemangiomas) are being treated with 68 MeV protons since 1998 at the Ion Beam Laboratory of the Hahn-Meitner Institute of Berlin (Germany's first proton therapy center), in cooperation with the Charite University Hospital in Berlin, Campus Benjamin Franklin. The proton beam, generated via a combination of Van de Graaff accelerator and cyclotron, is prepared by passive shaping for conformal tumor irradiation. A digital X-ray verification of the tumor location with the patient in sitting position limits the position uncertainties to a maximum of 0,3 mm. The treatment planning is performed using the program EYEPLAN. OCTOPUS, a CT-based planning program developed in cooperation with the German Cancer Research Center of Heidelberg, is under pre-clinical testing. Thus far, more than 400 patients have been irradiated. The first results are comparable to those obtained in other proton therapy centers. At the end of 2002, the University Hospital of Essen has also become a cooperation partner of the Hahn-Meitner Institute. (orig.)

    2016-03-08

    In this work, supply curves for 22 major oil producing countries were identified and then aggregated into global supply curves. According to the identified supply curves, almost all oil-producing oil projects currently under development in the study countries are also profitable at the current oil price of $ 35 to $ 40 per barrel, taking short-term marginal costs into account. However, if the price of oil remains at this level in the coming years, a supply bottleneck on the global oil market will occur until 2024, as the development of cost-intensive, unconventional deposits and of deposits in deep and very deep waters is necessary to meet future demand. In order to avoid such a supply bottleneck by 2024, an oil price of at least US $ 80 per barrel is required, according to the long-term market equilibrium determined. [German] In dieser Arbeit wurden Angebotskurven fuer 22 bedeutende Oelfoerderlaender ermittelt und anschliessend zu globalen Angebotskurven aggregiert. Gemaess den ermittelten Angebotskurven sind nahezu alle gegenwaertig in der Foerderphase befindlichen Oelprojekte in den Untersuchungslaendern auch beim aktuellen Oelpreis von 35 bis 40 US-$ je Barrel unter Beruecksichtigung der kurzfristigen Grenzkosten rentabel. Sollte der Oelpreis jedoch in den kommenden Jahren auf diesem Niveau verharren, wird es bis zum Jahr 2024 zu einem Angebotsengpass auf dem globalen Oelmarkt kommen, da zur Deckung der zukuenftigen Nachfrage die Erschliessung kostenintensiver, unkonventioneller Lagerstaetten und von Lagerstaetten in tiefen und sehr tiefen Gewaessern notwendig ist. Damit es bis zum Jahr 2024 nicht zu einem solchen Angebotsengpass kommt, ist gemaess des ermittelten langfristigen Marktgleichgewichts ein Oelpreis von mindestens 80 (2014er) US-$ je Barrel notwendig.

    As a prerequisite for MR-guidance of interventional procedures, instruments have to be well depicted in the MR image without obscuring or distorting the underlying anatomy. For non-vascular interventions the imaging speed has to be in the range of seconds while control of vascular interventions requires real time imaging speed. The imaging contrast has to be maintained as well as a high spatial resolution. Furthermore, sufficient patient access has to be provided by the MR scanner. Neither an ideal magnet nor the optimal single sequence are available to fulfill the above-mentioned criteria. The type of sequence - gradient echo versus spin echo - together with changing of the echo time and phase encording direction will ensure an appropriate size of the artifact and thereby of the appearance of the instrument in the MR image. The feasibility of non-vascular MR-guided interventions has been proved at field strengths ranging from 0.064 T to 1.5 T. Bone biopsies, soft tissue biopsies, drainages, and control of interstitial thermo- and cryotherapy have been reported. For vascular interventions, different real time MR strategies are currently under investigation. The development of dedicated catheters and guide wires has enabled MR-guided dilatations, stenting, placement of vena cava filters, and TIPS procedures. Considering the fast progress being made in this field, there can be no question that interventional MRI will become a well-accepted clinical tool offering potential advantages such as excellent soft tissue contrast, multiplanar imaging, flow measurements, high resolution imaging of vessel walls, and lack of ionizing radiation. (orig.) [German] Zur Durchfuehrung MR-gesteuerter Interventionen muessen interventionelle Instrumente gut sichtbar, aber ohne stoerende Artefakte darstellbar sein.

    Arbeit beschaeftigt sich mit einem drei- zu zweiphasigen Matrixumrichter zur Speisung von kontaktlosen Energieuebertragungssystemen. Aufbauend auf einer Darlegung relevanter Untersuchungen zur Thematik werden zunaechst moegliche Resonanzanordnungen fuer kontaktlose Energieuebertragungssysteme untersucht. Die Betrachtung wichtiger elektrischer Parameter zeigt neben den Unterschieden der einzelnen Anordnungen auch, dass fuer eine auf den speisenden Umrichter fokussierte Untersuchung eine einfache Modellierung der drei untersuchten Resonanzanordnungen mit Hilfe eines Reihenschwingkreises moeglich ist. Als Konsequenz ergibt sich die Schlussfolgerung, dass sich die erzielten Ergebnisse auch fuer den Matrixumrichter mit anderen serienresonanten Lasten anwenden lassen. Der zweite Teil der Arbeit ist der Untersuchung des Matrixumrichters gewidmet. Basierend auf einer theoretischen Beschreibung wird die Kombination von hochfrequenten Steuerverfahren - wie z.B. der Blocktaktung - und niederfrequenten Pulsmustern zur Stellung des Oberschwingungsgehalts der Netzstroeme vorgestellt. Die Aehnlichkeit des Umrichters zu einem konventionellen Wechselrichter in H-Brueckenschaltung ermoeglicht anschliessend eine Betrachtung der Kommutierung und die Ableitung notwendiger Schaltzustaende. Diese sind dadurch gekennzeichnet, dass zu jedem Zeitpunkt genau eine bidirektionale Verbindung vom Eingangssystem zu jeder Ausgangsphase besteht. Die Funktionsweise der Kommutierung wie auch des gesamten Umrichters wird in einem ersten Schritt simulativ belegt. Dabei wird auch das dynamische Schaltverhalten der Leistungshalbleiter beruecksichtigt. Anschliessend werden an einem Laboraufbau aufgenommene Messergebnisse vorgestellt und mit den theoretischen Ergebnissen verglichen. Der Laboraufbau besteht aus dem Leistungsteil des Matrixumrichters mit Eingangsfiltern und modularen Gate-Treibern, einem DSP/FPGA-Steuerungssystem und einem kontaktlosen Energieuebertragungssystem mit sekundaerseitigem Gleichrichter

Die Ganzkoerper-low-dose-CT und Ganzkoerper-MRT ermoeglichen eine Darstellung sowohl des mineralisierten Knochens als auch des Knochenmarks mit einer hoeheren Sensitivitaet, hoeherem Patientenkomfort und im Falle der MRT ohne Strahlenbelastung. Nach den Ergebnissen der Literatur sind Schnittbildverfahren dem Roentgenskelettstatus signifikant ueberlegen, wobei die Ganzkoerper-MRT fuer den Nachweis insbesondere eines diffusen Knochenmarkbefalls signifikant besser ist als die Ganzkoerper-CT. Praktisch jeder osteodestruktive Herd ist in der MRT sichtbar. Allerdings ist fuer die Beurteilung der Osteodestruktion selbst wiederum eine CT erforderlich. Die Sensitivitaeten von PET/CT und MRT sind vergleichbar. Wie bereits in einigen Zentren insbesondere in Deutschland umgesetzt, sollten bei Verfuegbarkeit das Ganzkoerper-MRT und das Ganzkoerper-CT den konventionellen Roentgenskelettstatus ersetzen. Bei Erstdiagnose bzw. Verdacht auf eine monoklonale Gammopathie unklarer Signifikanz (MGUS), ''smoldering multiple myeloma'' und symptomatisches multiples Myelom sollten sowohl eine Ganzkoerper-MRT als auch eine Ganzkoerper-CT durchgefuehrt werden. Bei asymptomatischem Myelom oder MGUS waere die Ganzkoerper-MRT bis zur Detektion des ersten umschriebenen Myelomherdes ausreichend. Beim symptomatischen Myelom mit Knochenlaesionen sollten in der Regel die Ganzkoerper-CT und fuer spezielle Fragestellungen die MRT eingesetzt werden. (orig.)

    Fusion development has many different challenges in the areas of plasma physics, fusion technologies, materials development and plasma wall interaction. For making fusion power a reality, a coherent approach is necessary, interlinking the different areas of work. To this end, the German fusion program started in 2010 the German DEMO Working Group, bringing together high-level experts from all the different fields, from the 3 German fusion centers Max-Planck-Institut fuer Plasmaphysik (IPP), Karlsruher Institut fuer Technologie (KIT) and Forschungszentrum Juelich (FZJ). An encompassing view of what will be needed with high priority, in plasma physics, in fusion technology and in the interrelation of the fields, to make fusion energy real, has been elaborated, and is presented here in a condensed way. On this basis, the 3 German fusion centers now are composing their work program, towards a fusion demonstration reactor DEMO. (orig.)

    We report optimized auxiliary basis sets for use with the Karlsruhe segmented contracted basis sets including moderately diffuse basis functions (Rappoport and Furche, J. Chem. Phys., 2010, 133, 134105) in resolution-of-the-identity (RI) post-self-consistent field (post-SCF) computations for the elements H-Rn (except lanthanides). The errors of the RI approximation using optimized auxiliary basis sets are analyzed on a comprehensive test set of molecules containing the most common oxidation states of each element and do not exceed those of the corresponding unaugmented basis sets. During these studies an unsatisfying performance of the def2-SVP and def2-QZVPP auxiliary basis sets for Barium was found and improved sets are provided. We establish the versatility of the def2-SVPD, def2-TZVPPD, and def2-QZVPPD basis sets for RI-MP2 and RI-CC (coupled-cluster) energy and property calculations. The influence of diffuse basis functions on correlation energy, basis set superposition error, atomic electron affinity, dipole moments, and computational timings is evaluated at different levels of theory using benchmark sets and showcase examples.

    The transformation into a vitrified block of highly radioactive liquid wastes is actually the best solution for the storage in long run. In West Germany, the research institute in the field of nuclear energy (KfK) has been oriented in this way by developing industrial processes of vitrification and by following studies on the behaviour of the final products. For the fission products, the chosen glasses present good stability characteristics and are used as a first barrier during confinement. Our work, which is part of the research program on radioactive waste vitrification, consists of preparing borosilicate glass GP 98/12 and studying physical and chemical characteristics. We have also contributed to the development and the realization of glass blocks sampling system prepared at pilot scale

By showing that the common claim that Lachmann's idiosyncratic (read: eclectic and multidisciplinary) approach to economics entails nihilism is unfounded, it reaches the following conclusions. (1......) Lachmann held a sophisticated institutional position to economics that anticipated developments in contemporary new institutional economics. (2) Lachmann's sociological and economic reading of institutions offers insights for the problem of coordination. (3) Lachmann extends contemporary new institutional...... theory without simultaneously denying the policy approach of comparative institutional analysis.

  4. What are Institutional Logics

    OpenAIRE

    Berg Johansen, Christina; Bock Waldorff, Susanne

    2015-01-01

    This study presents new insights into the explanatory power of the institutional logics perspective. With outset in a discussion of seminal theory texts, we identify two fundamental topics that frame institutional logics: overarching institutional orders guided by institutional logics, as well as change and agency generated by friction between logics. We use these topics as basis for an analysis of selected empirical papers, with the aim of understanding how institutional logics contribute to...

    There are various financing and organisation models in use at German waste treatment plants. These models have an influence on capital costs as well as on operating costs. The great variety of existing models, which is not only found in theory but also in practice, is a sure indication that there is no universal solution at present but that models always have to be adapted to the current conditions governing the plant in question (e.g., tax law amendments). In view of the great complexity of this subject the following deliberations will be restricted to only the best-known types of financing model. [Deutsch] Fuer den Betrieb von Abfallbehandlungsanlagen gibt es bundesweit verschiedene Organisations- und Finanzierungsmodelle. Diese Modelle haben Auswirkungen auf die Kapitalkosten und die Betriebskosten. Die Vielfalt der nicht nur theoretisch moeglichen, sondern auch der in der Praxis existierenden Modelle ist mit Sicherheit ein Hinweis, dass derzeit keine universelle Loesung moeglich ist, sondern diese immer den aktuellen und spezifischen Verhaeltnissen (z.B. Steuerrechtsaenderung u.a.) angepasst werden muss. Auf Grund der Komplexibilitaet beschraenken sich die nachfolgenden Ausfuehrungen ausschliesslich auf die bekanntesten Formen der Finanzierungsmodelle. (orig./SR)

    Processes in which a heat pump cycle is driven by thermal energy may be defined as heat transformation processes. The technical realization of this type of processes in general is based on sorption techniques. Depending on the temperature level of the utilized heat these technologies may be used for either cooling or heating of buildings. The paper presents state-of-the-art technologies and new developments. It comprises solar cooling of buildings, utilization of environmental energy sources (earth, air) by thermal driven heat pumps and seasonal storage of solar thermal energy by means of sorption processes. (orig.) [Deutsch] Unter Waermetransformationsverfahren werden im allgemeinen Verfahren verstanden, in denen ein Waermepumpenprozess mit thermischer Energie angetrieben wird. Die technische Realisierung dieser Verfahren erfolgt ueberwiegend mit Hilfe von Sorptionsvorgaengen. Abhaengig vom Temperaturniveau des Nutzwaermestroms koennen solche Verfahren im Gebaeudebereich fuer die Kuehlung oder Heizung eingesetzt werden. Im Beitrag werden der Stand der Technik sowie neue Entwicklungen vorgestellt. Im einzelnen umfasst der Beitrag die solare Kuehlung von Gebaeuden, die Nutzung von Umweltenergie (Erdreich, Luft) mittels thermisch angetriebener Waermepumpen sowie die saisonale Speicherung von Solarenergie ueber Sorptionsprozesse.

    Deutsche Bahn is presently endeavouring to further improve the interaction between the overhead wire and the current collectors on its locomotives and trainsets. The major factors behind this initiative are cost, quality and noise prevention. The outcome is the development of a completely new type of current collector for high-speed operation even on conventional track. Prototypes have meanwhile undergone practical trials on the 200 km/h line from Augsburg to Donauwoerth. The new current collector is a single-arm pantograph jointly developed by DB and Bombardier Transportation. (orig.) [German] Die Deutsche Bahn versucht derzeit, das Zusammenspiel von Oberleitung und den Stromabnehmern ihrer Lokomotiven und Triebzuege weiter zu verbessern. Kosten, Qualitaet und Laermschutz sind dabei die wesentlichen Gruende. Sie haben zur Entwicklung eines voellig neuen Stromabnehmer-Typus speziell fuer den Hochgeschwindigkeitsverkehr auch auf konventionellen Strecken gefuehrt. Auf der Tempo-200-Strecke von Augsburg nach Donauwoerth absolvierten jetzt Prototypen erste Praxis-Tests. Es handelt sich um aktiv geregelte, akustisch optimierte Einholmstromabnehmer, gemeinsam entwickelt von DB und Bombardier Transportation. (orig.)

    Due to their efficient heat insulation, modern low-energy houses can develop disagreeably high room temperatures in the summer. Use of room cooling devices for cooling residential buildings in central Europe is not feasible for ecological as well as economic reasons. This paper presents the buried heat exchanger and the cellar wall exchanger as alternatives to the cooling of incoming air in ventilated low-energy residential buildings. Both are in principle cold storages with coiled pipes taking in air from outside. The buried heat exchanger is charged with cold during the heating period (seasonal storage), whereas the cellar wall exchanger accumulates and gives off cold daily. (orig.) [German] In modernen Niedrigenergiehaeusern koennen sich aufgrund einer verbesserten Waermedaemmung waehrend des Sommers Raumtemperaturen einstellen, die nicht als behaglich empfunden werden. Raumkuehlgeraete scheiden aus oekologischen und oekonomischen Gruenden fuer eine Kuehlung von Wohngebaeuden in Mitteleuropa aus. Als Alternativen zur Kuehlung der Zuluft bei Niedrigenergiehaeusern mit Wohnungslueftung werden der Erdwaermeaustauscher und der Kellerwandaustauscher vorgestellt. Hierbei handelt es sich um Kaeltespeicher, in welchen Rohrschlangen verlegt sind, ueber welche die Aussenluft angesaugt wird. Der Erdwaermeaustauscher wird als Kaeltespeicher waehrend der Heizperiode aufgeladen (saisonaler Speicher), wohingegen der Kellerwandaustauscher taeglich be- und entladen wird. (orig.)

    Magnetic resonance imaging (MRI) of the liver has become an essential tool in the radiological diagnostics of both focal and diffuse diseases of the liver and is subject to constant change due to technological progress. Recently, important improvements could be achieved by innovations regarding MR hardware, sequences and postprocessing methods. The diagnostic spectrum of MRI could be broadened particularly due to new examination sequences, while at the same time scanning time could be shortened and image quality has been improved. The aim of this article is to explain both the technological background and the clinical application of recent MR sequence developments and to present the scope of a modern MRI protocol for the liver. (orig.) [German] Die Magnetresonanztomographie (MRT) der Leber ist in der radiologischen Diagnostik fokaler und diffuser Lebererkrankungen fest etabliert und untersteht einem steten Wandel durch den fortwaehrenden technischen Fortschritt. Durch Neuerungen bei der Hardware, den Sequenzen und der Bildnachverarbeitung konnten in den letzten Jahren deutliche Fortschritte erzielt werden. Insbesondere auf dem Gebiet der Untersuchungssequenzen kam es zu Entwicklungen, die das diagnostische Spektrum der MRT erweiterten, zu einer Verkuerzung der Scanzeit fuehrten und zu einer Verbesserung der Bildqualitaet beitrugen. Gegenstand dieses Artikels ist es, den technischen Hintergrund und die klinische Anwendung neuerer Sequenztechniken zu erklaeren und so die Moeglichkeiten und den Umfang eines modernen MRT-Untersuchungsprotokolls fuer die Leber darzustellen.

    In Thuringia the maize represents with a current size of the cultivation of less than 10% and a cultivation concentration of less than 20% in every county an enrichment of crop rotation. The recycling of the digestate in the farm results due to higher C-reduction stability of the fermentation products to any deterioration of the C balance and soil fertility. Especially in Thuringia farming regions with very low livestock the introduction of biogas plants introduces to a higher diversity of agricultural production and dispersal of crop rotation. Practiced by the combination of locally adapted biogas plants with animal husbandry (milk production = use manure, pig = heat utilization) positive economic and environmental effects can be achieved for the Thuringian farmers. [German] In Thueringen stellt der Mais bei einem gegenwaertigen Anbauumfang von unter 10 % und einer Anbaukonzentration von unter 20 % in jedem Landkreis eine Bereicherung der Fruchtfolge dar. Die Verwertung der Gaerreste im Betrieb fuehrt infolge hoeherer C-Abbaustabilitaet der Gaerprodukte zu keiner Verschlechterung der C-Bilanz und der Bodenfruchtbarkeit. Besonders in Thueringer Ackerbauregionen mit sehr geringem Tierbesatz traegt die Einfuehrung von Biogasanlagen zu einer hoeheren Vielfalt der landwirtschaftlichen Produktion und Auflockerung der Fruchtfolgen bei. Durch die praktizierte Kombination von standortangepassten Biogasanlagen mit der Tierhaltung (Milcherzeugung = Guellenutzung, Schweinehaltung = Waermenutzung) werden fuer die Thueringer Landwirte positive oekonomische und oekologische Effekte erzielt.

    Present methods for quantifying radiation exposure rely on a standardized reference man (75 kg) with defined average anatomical and physiological data. But individual person actually exposed differs from this idealized standard man. Therefore the focus of investigations at the Institute for Radiation Research (Institut fuer Strahlenforschung, ISF) which was founded at Karlsruhe Institute of Technology (Karlsruher Institut fuer Technologie, KIT) in 2009 is based on the vision to place the exposed individual with its anatomical and physiological particularities, under consideration of age, gender, body height, body shape and environment, in the centre of an individual-related quantification of the external and internal radiation exposure. Research work at the ISF is aiming at quantifying radiation exposure by improved determination of doses essentially caused by external radiation fields and the intake of radionuclides into the body. The three main topics of the institute are - external dosimetry (e.g. using a (voxel) model of the hand to simulate skin dose distribution); - internal dosimetry (e.g. body size related efficiency calibration of in-vivo counting equipment); - numerical methods/modeling (e.g. development of a mathematical/voxel-hybrid model of the human body).

    Besides the positive effect of energy saving the aspect of fungi formation has also to be respected. Fungi is not only responseable for health diseases but can also damage building materials. Examples are shown and how they can be detect by an infrared monitoring camera. (GL) [German] Die Waermeschutzverordnung und das daraus hervorgegangene Energieeinspargesetz haben weitreichende Folgen fuer Architekten, Bauingenieure, Instandhalter und Sanierer: Zeitgemaesse Gebaeude werden immer dichter, Luftzirkulation und damit der Feuchtigkeitsaustausch werden weitgehend unterbunden. Neben dem positiven Effekt der Energieersparnis ergibt sich dadurch leider oft auch ein Problem durch Schimmelbildung. Dabei ist zu bedenken, dass Schimmelpilz nicht nur gesundheitsgefaehrend ist, sondern oft auch die Bausubstanz signifikant schaedigen kann. (orig.)

    Betriebsanleitung der MR-Scanner. Die verpflichtenden Inhalte der Betriebsanleitung werden in einer zentralen Norm der International Electrotechnical Commission (IEC) 60601-2-33 geregelt. In dieser Norm wurde juengst die Anwendung statischer Magnetfelder in der MRT bis zu 8 Tesla (T) in der klinischen Routine (kontrollierte Betriebsart 1. Stufe) zugelassen. Die ebenfalls notwendige CE-Zertifizierung der Ultrahochfeldscanner (7-8 T) in Europa ist fuer zukuenftige Geraete zu erwarten. Bestehende Installationen werden nicht automatisch zertifiziert, sondern behalten ihren experimentellen Status. Die aktuelle Erweiterung der IEC 60601-2-33 fuehrt eine neue Zusatzoption, die sog. ''fixed parameter option'' (FPO) ein. Diese Option kann zusaetzlich zu den etablierten Betriebsarten geschaltet werden und definiert eine fixe Geraetekonstellation und bestimmte Parameter des Energieoutputs von MR-Scannern, die zukuenftig die Untersuchungen von Implantatpatienten vereinfachen soll. Die Beschaeftigung schwangerer Mitarbeiterinnen in einer MRT-Einrichtung ist nach wie vor nicht allgemein in Europa geregelt. In Deutschland und Oesterreich wurden 2014 in Teilregionen Beschaeftigungsverbote fuer Schwangere und Stillende im der MR-Kontrollzone (0,5 mT) erteilt. Zugrunde liegt die meist ungeklaerte Frage der Anwendbarkeit von Grenzwerten fuer Beschaeftigte (Extremitaetenexposition fuer statische Magnetfelder bis 8 T erlaubt) oder der Grenzwerte fuer die Allgemeinbevoelkerung (maximal bis 400 mT). Das Verwerfen von Muttermilch nach i.v.-Gabe von gadoliniumhaltigen Kontrastmitteln bei einer stillenden Frau wird laut Gesellschaft fuer urogenitale Radiologie (ESUR) nur noch bei Gabe von Kontrastmitteln der Nephrogenic-systemic-fibrosis(NSF)-Hochrisikoklasse empfohlen.

    Advanced simulation tools were used in developing the climate design for the roof covering the taller of the two blocks at Moscow's Federation Tower. The all-glass roof space at a height of 365 m is designed to accommodate the finest and most exclusive hotel areas. Several restaurants, bars and lounges and a Sky Dance Club will offer entertainment and fabulous views across the whole city. Simulations were used to develop and verify a design that ensures thermal comfort taking into account architectural, climate and utilisation requirements. The structure and the building services were simulated based on a 3D model, and simulations were carried out for summer and winter scenarios. This paper describes the design process including load calculations and the development and assessment of the climate design by means of simulation.

    A liquid nitrogen pump with contactless superconducting magnetic bearings was to be developed on the basis of an available motor with superconducting bearings. Contactless superconducting magnetic bearings require practically no servicing. A high demand for pumps for cryogenic liquids is expected with the impending use of hydrogen as an energy source. The pumping of liquid nitrogen was demonstrated successfully with the new test aggregate. The maximum pumped volume was 17 l/min at a lift of 0.5 m and 6 l/min at a lift of 1 m. In all, 15 hours of operation were registered in the superconducting state of the bearing, which included 2 hours of uninterrupted pump operation. The higher speed range for which magnetic bearings are optimally suited was not reached. Operation at higher frequencies was impossible either because of stronger resonance amplituees or because the power system was too weak. [German] Ziel des Vorhabens war die Entwicklung einer Pumpe fuer fluessigen Stickstoff mit beruehrungslosen supraleitenden Magnetlagern auf der Basis eines vorhandenen supraleitend gelagerten Motors. Die beruehrungslose supraleitende Magnetlager sind praktisch wartungsfrei. Ein Bedarf an Pumpen fuer kryogene Fluessigkeiten entsteht insbesondere durch den in naher Zukunft zu erwartenden Einsatz von Wasserstoff als Energietraeger. Mit dem entworfenen Aggregat wurde das Pumpen von Fluessigstickstoff erfolgreich demonstriert. Der Foerderstrom betrug bei 0,5m Foerderhoehe maximal 17 l/min; beim 1m Foerderhoehe wurden maximal 6 l/min gemessen. Es wurden insgesamt ca. 15 Betriebsstunden in supraleitenden Zustand des Lagers, darunter 2 Stunden ununterbrochener Pumpbetrieb registriert. Der hoehere Drehzahlbereich, fuer den das Magnetlager eigentlich paedestiniert ist, konnte nicht erreicht werden. Ein Betrieb bei hoeheren (Ist-)Frequenzen war nicht moeglich, entweder durch staerkere Resonanzausschlaege oder durch einen zu schwachen Antrieb. (orig.)

    A cooperative effort of the Center for Solar Energy and Hydrogen Research (ZSW) and Phototronics Solartechnik GmbH (PST) aimed at the transfer of highly efficient solar cells developed on a laboratory scale, to large-area thin-film solar modules suitable for production. This work was based on research and development at the Institute for Physical Electronics (IPE) of Stuttgart University and ZSW on one hand, and on the know-how of PST in regard to large-area module fabrication on the other hand. The various thin-film layers of the cells and modules comprize molybdenum as rear contact, copper-indium(gallium)-diselenide (CIGS) as absorber material, the combination of cadmium sulphide (CdS) and ZnO as window layer. To produce these layers on large areas (30x30 cm{sup 2}), equipment was constructed and procedures were developed. Monolithic series connection of cells, used in other thin-film technologies, was studied and optimized by suitable patterning procedures, such as laser-scribing, mechanical scribing or lift-off techniques. Central to the PST efforts was the large-area deposition of Mo followed by patterning for the monolithic series connection, and furthermore important contributions in regard to the ZnO window layer as well as aspects of the module technology. The latter include film removal along the module edges, contacting and cable attachment, lamination, module measurements and temperature/humidity tests. The main goal, namely the basic development of equipment and procedures to fabricate large-area (30x30 cm{sup 2}) modules with an efficiency of 10-12%, was reached (best module with 11.7% efficiency referenced to the aperature area).

    The marine environment of the North Sea and Baltic Sea is still heavily polluted. The marine ecosystems are under severe stress from overfishing, water pollution, raw materials production and tourism. Environmental protection in this region necessitates decisive political initiatives and strict corrections especially in fishery policy, agricultural policy and chemical substances control. This is the balance of the special expert opinion of the Council of Environmental Experts. The publication specifies the main problem areas, the current pollution situation, the fields where action is most urgently required - especially in fishery, chemical substances, agricultural and sea travel policies - and presents suggestions for an integrated European and national marine protection policy including a regional development concept for the marine environment. (orig.) [German] Die Meeresumwelt von Nord- und Ostsee ist nach wie vor stark belastet. Ueberfischung, Schadstoffeintraege und Ueberduengung sowie die intensive Nutzung durch Schifffahrt, Rohstoffabbau und Tourismus beeintraechtigen vielfach massiv die marinen Oekosysteme. Ein wirksamer Meeresumweltschutz erfordert daher einschneidende politische Initiativen und grundlegende Korrekturen insbesondere in der Fischereipolitik, der Agrarpolitik und bei der Chemikalienregulierung. Diese Bilanz zieht der Rat von Sachverstaendigen fuer Umweltfragen in seinem aktuellen Sondergutachten 'Meeresumweltschutz fuer Nord- und Ostsee'. Das Sondergutachen - gibt einen Ueberblick ueber die wichtigsten Problemfelder und die aktuelle Belastungslage, - zeigt den wesentlichen Handlungsbedarf auf, insbesondere fuer die Fischerei-, Chemikalien-, Agrar- und Schifffahrtspolitik und - entwickelt Vorschlaege fuer eine integrierte europaeische und nationale Meeresschutzpolitik einschliesslich einer Merresraumordnung.

    Double layer capacitors are the system of choice whenever a large number of cycles and high capacity are required. They have the advantages of high cyclic strength, high capacity, freedom of servicing, insensitivity to high temperatures and long life. Drawbacks are low energy density, high self-discharge and high cost.Applications in water pumps, pathfinders and roller blind control systems were investigated. [German] Mit den Ergebnissen steht ein detailliertes Wissen ueber den weltweiten Entwicklungsstand und die physikalischen Eigenschaften von Doppelschichtkondensatoren zur Verfuegung. Ihre Eigenschaften wurden in Bezug auf moegliche photovoltaische Anwendungen hin analysiert. Anwendungsfehlder ergeben sich vorzugsweise dann, wenn hohe Zyklenzahl und Leistungsfaehigkeit gefordert werden. Die Vorteile des neuen Energiespeichers sind seine hohe Zyklenfestigkeit und Leistungsfaehigkeit, seine Wartungsfreiheit, Temperaturunempfindlichkeit und lange Lebensdauer. Ihnen stehen die Nachteile einer geringen Energiedichte, hohen Selbstentladung und hoher Kosten gegenueber. Eine deutliche Steigerung der Gesamteffizienz von photovoltaischen Versorgungseinheiten beim Einsatz von Doppelschichtkondensatoren ergeben energetische Simulationen unterschiedlicher Systeme. Fuer ausgewaehlte photovoltaisch versorgte Anwendungen konnte die Einsatzfaehigkeit von Doppelschichtkondensatoren in Feldtests erprobt und nachgewiesen werden. Wasserpumpensysteme, Pathfinders und eine Rolladensteuerung fuer ein Fenster wurden getestet. Der Einsatz von Doppelschichtkondensatoren zur weiteren Verbreitung photovoltaischer Anwendungen ist bereits heute fuer spezielle Anwendungen sinnvoll und wirtschaftlich. Mit weiter fallenden Preisen fuer die Kondensatoren und der Entwicklung von Kondensatorsystemen mit hoeheren Spannungen werden weitere Anwendungsfelder hinzukommen. Die Basis zur Entwicklung der notwendigen Systemtechnik und ihrer Demonstration in Feldversuchen ist durch die Ergebnisse des

    guenstigen Kraftstoffverbrauch eines Dieselfahrzeugs beizubehalten. Vor diesem Hintergrund werden im Rahmen dieses Beitrages brennverfahrensseitige Massnahmen sowie Abgasnachbehandlungskonzepte hinsichtlich Wirkungsgrad undd Einfluss auf den Kraftstoffverbrauch analysiert. Es kann festgehalten werden, dass fuer den Pkw-Dieselmotor noch ein beachtliches Emissionsreduktionspotenzial erschlossen werden kann. Eine Erfuellung der nach 2005 diskutierten bzw. schon beschlossenen Emissionsgrenzwerte allein durch Weiterentwicklung des Brennverfahrens erscheint allerdings aus heutiger Sicht als schwierig. Insbesondere vor dem Hintergrund des Kraftstoffverbrauchs stellt sich eine geeignete Kombination von innermotorischen Massnahmen und Abgasnachbehandlung als der sinnvollere Weg dar. Entscheidend fuer den Erfolg eines solchen Konzeptes wird die Leistungsaufnahme der Abgasnachbehandlungsmassnahme im weitesten Sinne sein. Dazu zaehlt sicherlich das Thermomanagement von Motor und Abgassystem. Darueber hinaus muessen aber auch die Faktoren beruecksichtigt werden, die das Regenerationsverhalten der diskontinuierlich betriebenen Nachbehandlungssysteme Partikelfilter und NO{sub x}-Speicherkatalysator bestimmen. Hier sind in erster Linie das Kraftstoffadditiv und der Kraftstoffschwefel bzw. die Schwefelproblematik des NO{sub x}-Speicherkatalysators zu nennen. (orig.)

    R and D activities at IRB (Institut fuer Reaktorbauelemente - Institute for Reactor Components) are dedicated to thermodynamics and fluid dynamics. Emphasis is on the design of nuclear reactor and fusion reactor components. Environmental engineering was added recently. Most activities are applications-oriented. Fundamental investigations focus on energy research and energy technology. The activities are carried out in the framework of different projects (PKF/nuclear fusion, PSF/nuclear safety, PSU/pollution control). Points of main effort are the development of basic liquid-metal-cooled blanket solutions, investigations on natural convection in reactor ranks, and the cooling properties of future containments for pressurized water reactors in the case of nuclear fusion accidents.

    The aim of this review is to evaluate the role of inflammatory spine disease in patients with chronic back pain. The contribution of imaging modalities for the diagnostic evaluation of back pain is discussed. A systematic literature search based on the classification of seronegative spondyloarthropathies and rheumatoid arthritis was performed. The results of this search and the experiences in a large collective of rheumatological patients are analyzed. The prevalence of rheumatoid arthritis (1-2%) is comparable to that of spondyloarthropathies (1.9%). The etiology of these entities is not fully elucidated. Magnetic resonance imaging is increasingly used for early detection and surveillance of therapy with TNF-{alpha} antagonists. Bone marrow edema, which is only detectable with MRI, represents an early sign of inflammation. Therapy with TNF-{alpha} antagonists is based on clinical and laboratory criteria, and signs of inflammation in MRI. MRI is useful for assessment of the effectiveness of anti-inflammatory therapy. (orig.) [German] Ziel der Arbeit ist, die Bedeutung inflammatorischer Wirbelsaeulenerkrankungen fuer das Leitsymptom Rueckenschmerz zu eroertern. Die Aussagekraft der verschiedenen radiologischen Verfahren wird diskutiert. Basierend auf der Einteilung der seronegativen Spondylarthropathien (SpA) sowie der rheumatoiden Arthritis (RA), erfolgte eine systematische Literaturrecherche. Die Ergebnisse dieser Recherche und die eigenen Erfahrungen mit einem grossen rheumatologischen Krankengut werden analysiert. Die Praevalenz der RA (1-2%) und der Gruppe der SpA (1,9%) ist vergleichbar, wobei die Aetiologie letztlich bei keiner der genannten Erkrankungen bekannt ist. Die bildmorphologische Kriterien koennen sich ueberlappen. Die MRT wird zunehmend bei Frueherkennung und Verlaufsbeurteilung der immunmodulatorischen Therapien (TNF-{alpha}-Antagonisten) eingesetzt. Ein Oedem im Knochen, das nur mit der MRT nachweisbar ist, zeigt die Aktivitaet der Entzuendung

    For the accurate measurement of gas density in natural gas meter runs, a special test densimeter has been developed. It covers a temperature range from 0 C to 50 C at pressures up to 100 bar; its total uncertainty is {<=}{+-}0.05% for densities {>=}20 kg/m{sup 3}. The new densimeter has been specially designed as a portable device for in situ checking of commercial gas density transducers (with vibrating thin-walled metal cylinders or vibrating forks as density sensors) installed in natural gas meter runs with density converters or differential-producing meters. Also, it can be used in natural gas meter runs with PTZ converters to check the density calculated by the converter or to check verification measurements. This paper describes the measurement principle and the design of the densimeter and presents the results of field measurements performed. (orig.) [German] Zur genauen Messung der Dichte von Erdgasen unter Betriebsbedingungen wurde ein spezielles Dichtepruefgeraet entwickelt. Der Einsatz des Geraetes ist bei Gastemperaturen von 0 C bis 50 C und bei Druecken bis 100 bar moeglich; die Gesamtmessunsicherheit betraegt {<=}{+-}0,05% fuer Dichten {>=}20 kg/m{sup 3}. Das neue Dichtepruefgeraet ist gezielt als transportables Geraet zur Online-Pruefung von kommerziellen Betriebsdichteaufnehmern (mit Schwingzylindern oder Schwinggabeln als Dichtesensor) in Erdgasmessstationen mit Dichte-Mengenumwertern oder Wirkdruckgaszaehlern entwickelt worden. Es kann ebenfalls in Messstationen mit Zustands-Mengenumwertern zur Kontrolle der vom Umwerter errechneten Betriebsdichte oder zur Kontrolle von Revisions-Messungen eingesetzt werden. Im folgenden Artikel werden das Messprinzip, der Aufbau des Geraetes und der Einsatz vor Ort beschrieben. (orig.)

    Due to the Spanish climate (hot summers throughout large parts of the country) the household and small consumers sector in this country has a substantial requirement for cold production. Today most industrial and commercial buildings here such as office blocks, shopping centres, hospitals, hotel etc. are equipped with air conditioning plants. Usually these are based on compression refrigeration plants. Beyond this air conditioning plants are now also beginning to become popular in one-family houses and flats, especially in southern and western Spain and along the Mediterranean coast. In most cases these plants, too, work with compression refrigeration, though it is not uncommon to find steam-based refrigeration systems. Both these types of system are driven by electricity. In the industrial sector, too, the market for refrigeration shows a very wide spectrum across a large variety of branches. (orig./HW) [Deutsch] In Spaniens HuK-Sektor (Haushalte und Kleinverbraucher) besteht aufgrund der herrschenden klimatischen Bedingungen (sehr warme Sommer in weiten Teilen des Landes) ein erheblicher Bedarf an der Erzeugung von Kaelte. Die meisten Industrie- und gewerblichen Gebaeude, wie Buerokomplexe, Einkaufszentren, Krankenhaeuser, Hotels, usw. sind mittlerweile mit Klimaanlagen ausgeruestet. Im allgemeinen handelt es sich hierbei um Kompressionskaelteanlagen. Vornehmlich in Sued- und Zentralspanien sowie an der Mittelmeerkueste haben Klimaanlagen inzwischen aber auch verstaerkt in Einfamilienhaeusern und Wohnungen Einzug gehalten. Vorwiegend sind Kompressionskaelteanlagen im Einsatz; haeufig sind aber auch Systeme anzutreffen, die auf Wasserdampfbasis arbeiten. Energietraeger ist bei beiden Systemen Strom. Der Markt fuer Kaelteerzeugung ist auch im industriellen Bereich sehr breitgefaechert und umfasst eine Vielzahl von Branchen. Der Loewenanteil entfaellt jedoch auf die Nahrungsmittelindustrie.
