While individual encounters with the boundary layer plasma last only a few minutes, the total observation time may extend over 1 hour or more. One such crossing, at hours local time and 40 0 northern GSM latitude, is examined in detail, including a quantitative comparison of the boundary layer entry and exit times of the two spacecraft. The data are found to be compatible with a boundary layer that is always attached to the magnetopause but where the layer thickness has a large-scale spatial modulation pattern which travels tailward past the spacecraft.

It also appears that the purely magnetospheric plasma is ocassionally separated from the boundary layer by a halo region in which the plasma density is somewhat higher, and the temperature somewhat lower, than in the magnetosphere. A tentative model is proposed. Armouring facility? 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 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. Tutorium quantum mechanics. By an experienced tutor for students of physics and mathematics; Tutorium Quantenmechanik. Von einem erfahrenen Tutor - fuer Physik - und Mathematikstudenten. Tutorium quantum mechanics is a book, written by an experiences tutor for all, who finally want to understand from the beginning physics and mathematics of quantum mechanics.

The book treats the matter of the corresponding course in the framework of theoretical physics. The main topic lies in this book on the general postulates of quantum mechanics and the clarification of the fundamental terms. What is precisely a Hilbert space? What is an Hermitian operator? A tensor product? An entangled state? To what extend wave functions are vectors? The postulates raise until today also many questions concerning their interpretation. This is discussed in a separate chapter.

This book is structured in such a way that each step and each new term is explained by means of simple examples. The author attaches great importance to the clarity of the applied mathematics - something, what he and many students in other textbooks had hitherto to miss. By this main topic is also very well suited for mathematicists, who want to deal with the issue.

In the examination preparation the book is especially well suited for the clarification of terms and questions of understanding. The questions of understanding and the exercise problems interspersed in the text with solutions support additionally the learning and the preparation for examination. Quantum mechanics. Textbook for students of physics, mathematics and physical chemistry. The aim of the textbook now present in fourth edition is the representation of the fundamental physical concepts of the theory of quantum mechanics.

It is confined to the nonrelativistic quantum mechanics; however also themes are treated which are in an extended form important just for quantum field theory up to the modern development. With 22 figs. The aim of the textbook now present in fifth edition is the representation of the fundamental physical concepts of the theory of quantum mechanics.

X-ray anatomy - radiological imaging, radiation protection. For auxiliary medical personnel, technicians, physicists. Roentgenanatomie - radiologische Darstellung, Strahlenschutz. Fuer aerztliches Hilfspersonal, Techniker, Physiker. This third edition as the result of a complete revision of the second edition reflects the current state of the art and includes topical information on a variety of advances hitherto achieved, as for instance information on novel imaging techniques in diagnostic radiology that have been included in the chapters on physical fundamentals or examination methods, as well as in all chapters discussing the anatomy and the relevant radiological imaging methods.

As practice has shown that the application of the latest standards on radiation doses and units still poses problems, the authors decided to add a section explaining dose concepts, terminology and units. The two chapters dealing with contrast media and with radiological examination methods have been updated and supplemented. The anatomy chapters, written for readers who are not doctors, and the survey of the relevant diagnostic radiology still form the core of the book, but all in all this third edition now puts equal emphasis on all three aspects concerned, namely X-ray anatomy, radiological imaging, and radiation protection.

Final theory spiral-field-model. Basic ideas for a compatible physics and a consistent nature science; Finaltheorie Spiralfeldmodell. Grundgedanken fuer eine kompatible Physik und eine konsistente Naturwissenschaft. This script contains theses for an universal 'Spiral-Field-Theory' that are capable to dissolve problems in parallel from different areas which are far from each other. Starting point is the stuck principle discussion about the relationships between the Classic Physics and the Quantum Physics.

Aim is the clarification of questions which remained open. In Max Planck had formulated as follows: 'The research of physics can not rest, so long not has been together-welded: on the one hand the mechanics and the electrodynamics with on the other hand the lesson of the stationary one and the radiating heat to a sole unitary theory'. The Spiral-Field-Model develops a supporting structure from General Field into which they will class the secure knowledge from experiments and well-proved theories.

The most important thing of this new Final Theory is the detailed generating of all nature courses of phenomena exclusively from radiation and that in the direct meaning of the word. In the final effect the two great disciplines of the physics which are drifted from each other, become bonded together to a super ordinate theoretical building of the nature sciences.

Contributions to naive quantum mechanics. A textbook for mathematicians and physicists; Beitraege zur naiven Quantenmechanik. Ein Leitfaden fuer Mathematiker und Physiker. The present text examplifies by means of 60 citations from current textbooks for the study of physics the necessarity of a mathematically rigorous formulation of quantum mechanics. Well known statements of many physicists about quantum mechanics at their mathematical tool kit are commented in form of a dialogue und mathematical points of view.

Supplemented are the representations by a selection of theorems of higher analysis relevant for quantum theory. The book applies to mathematicians and mathematically interested physicists or students with founded mathematical knowledge. By an experienced tutor for students of physics and mathematics. The focus of this book lies on the general postulates of quantum mechanics QM , their interpretation, their fundamental terms, and their mathematical formulation.

The first and most comprehensive part of the book is dedicated to this thematics. In the second part an imported special case is treated: The QM of the wave functions in one, two, and three spatial dimensions under the condition, that the Hamiltonian operator consists only of the kinetic term and a timely independent potential. The most important examples hereby are the harmonic oscillator and the hydrogen atom.

Also the scattering theory is discussed in this framework. The third part comprehends further themes, which belong to the canonical matter of a QM course: Combination of spin and angular momentum, QM with electromagnetism, perturbation theory, and systems with several particles. Rounded off is the whole by a short explanation of the path-integral term and by the relativistic theory of the electron Dirac equation.

Target group of this book are students of physics, who hear QM in the framework of theoretical physics. By the axiomatically deductive approach and the detailed discussion of the mathematical background it is also very well suited for mathematicians, who want to come to an understanding of QM in the subsidiary subject or in their leisure time. Dieser Band behandelt die Physik des CERN Multimedia. The masses of galaxy clusters are important for the determination, for instance of the mean density and distribution of matter in the universe.

This is because these clusters are the most massive, clearly defined objects known and as such trace these parameters in the universe on very large scales. Another possibility to derive the cluster mass is offered by X-ray observations, because the distribution of the hot, X-ray emitting gas traces the gravitational field of the cluster. Recently, in some clusters there has been a discrepancy between the mass determined in this way and that found from gravitational lensing effects. The team of astronomers now hopes that follow-up X-ray observations of RXJ Moreover, the combination of extremely high X-ray brightness and the possibility to perform a rather accurate mass determination by the gravitational lensing effect makes this particular cluster a truly unique object.

In view of the exceptional X-ray brightness, a very high mass is expected. The exact determination will be possible, as soon as spectra have been obtained of the two arcs.

Bildung in the late 18th century: schöne Wissenschaften

Contrary to what is the case in other clusters, this will not be so difficult, due to their unusual brightness and their ideal geometrical configuration. Neumann and Ulrich G. The world-line. Albert Einstein and modern physics; Die Weltlinie. Albert Einstein und die moderne Physik.

This book is an entertaining and formula-free presentation of modern physics from the 19th century to present. The life of Albert Einstein and his scientific works are drawn as red fathom through the text. The author explains central terms and results of modern physics in populary-scientific form from the historical perspective. To the reader in humorous form an imagination is mediated how modern physics has been developed. We learn from the exciting effects of the ether, we hear from faraday and magnetic needles, from Maxwell's prediction of the electromagnetic waves, from heinrich Hertz and from the photoelectric effect.

Was the Michelson-Morley experiment a measurement success or an unsuccess? Why has Einstein abandoned the ether? How has Einstein in the miraculous year revolutionated physics and why he has begged Newton for excusement? Exist atoms? What is motion? What is light and what is to be understood under ''now'' and ''here''? Light deviation or non-deviation? How act the tidal forces? And above all: How has Einstein answered these questions. What had Eddington against Chandrasekhar and what had Einstein against black holes?

Why should space tourists and dream tourists make holiday not on the Loch Ness but on the safe side of a black hole? Why inveighed Pauli against Einstein? Is the concern with the atomic-bomb formula right? Smeared matter, big bang and cosmic background radiation, gravitational waves and double pulsars, the cosmological constant and the expansion of the universe are further themes, which keep the reader in breath and let no mental vacuum arise. Jahrhundert bis zur Gegenwart. Das Leben Albert Einsteins.

Jahrhunderts zu befassen. Research for energy efficiency; Forschung fuer Energieeffizienz. The Federal Ministry of Economy enhanced its funding for research in the field of non-nuclear energy in the programme ''Forschung fuer Energieeffizienz'' Research for Energy Efficiency. The programme focuses on established areas like modern power plant technologies ''Moderne Kraftwerkstechnologien'' , fuel cells and hydrogen ''Brennstoffzelle, Wasserstoff'' , and energy-optimized building construction ''Energieoptimiertes Bauen''.

New subjects are energy-efficient towns and cities ''Energieeffiziente Stadt'' , power grids for future power supply ''Netze fuer die Stromversorgung der Zukunft'' , power storage ''Stromspeicher'' , and electromobility ''Elektromobilitaet''. The brochure presents research and demonstration projects that illustrate the situation in when the programme was initiated. Energy revolution for Africa; Energierevolution fuer Afrika. Decreasing energy costs from renewable sources could enable many African countries to make the leap into a clean future.

This would save the continent the detour via the classic dirty sources. Damit wuerde sich der Kontinent den Umweg ueber die klassischen schmutzigen Quellen sparen. Bundesamt fuer Strahlenschutz The information on the Bundesamt fuer Strahlenschutz includes the following contributions: Bfs concentrates the radiation protection expertise; knowledge generation, knowledge testing knowledge application: the BfS as scientific organization; radiation protection and health; radiation protection and environment, safety of nuclear waste management; safety in nuclear technology; specific challenges for BfS.

Bundesanstalt fuer Strahlenschutz. The annual report of the Bundesamt fuer Strahlenschutz covers the following issues: from scientific research to preventive consumer protection, actual questions of radiation protection actual challenges in the frame of environmental radiation monitoring; radioactive waste disposal; actual questions on the safety of nuclear technology.

The report includes a list of publications. Synchrotron radiation gives insight in smaller and smaller crystals. Scientists from the '' Max-Planck-Institut fuer Festkoerperforschung'' in Stuttgart have extended the method of X-ray analysis to study the structure of very small crystals. Thus this important method of analysis has been demonstrated to be usefull for structural studies of crystals, which are smaller by a factor of 20 than hitherto.

Campbell, Chair of the CC, noted the significant enhancement of the physics basis for burning plasma experiments, which had been achieved via the ITPA collaboration. The Topical Group chairs reported on the most significant recent developments in their areas of responsibility. Surveys of radio sources at 5 GHz. The surveys fall into two categories: first, the strong source S surveys which are intended in due course to cover the whole northern sky and to be complete above a flux density of about 0. GIOVE: a new detector setup for high sensitivity germanium spectroscopy at shallow depth.

Heusser, G. Particular attention was paid to the design of a novel passive and active shield, aiming at efficient rejection of environmental and muon induced radiation backgrounds. Current status of fusion-relevant covariance data. The draft agenda of this meeting lists as Item 6 the ''assessment of present status and role of uncertainty files, their processing and sensitivity studies related to FENDL. Jahresbericht The annual report of the Institute of Hydrology presents the findings of 19 current research projects on different subjects in hydrology. It is supplemented by information on cooperation with other scientific institutions in the form of lists of publications and reports, lectures and posters, university teaching projects, and finished and current dissertations.

Ergaenzt werden die Ausfuehrungen durch einen Ueberblick ueber die Zusammenarbeit mit anderen wissenschaftlichen Institutionen in Form von Verzeichnissen der Veroeffentlichungen und Berichte, der Vortraege und Poster, der Beitraege zur Lehre an Hochschulen sowie der abgeschlossenen und laufenden Dissertationen. There is hardly another area of physics which has a comparable multiplicity of phenomena, like flow in multi-phase mixtures. The wishes of experimenters regarding measurement technique are correspondingly great: Apart from the conventional parameters of pressure, temperature and speed of flow, as great a collection with resolution of the instantaneous phase distribution is required.

Also, the phases themselves frequently consists of several components, whose concentration should also be measured. The enormous progress which has recently been made with laser optics and tomographic processes, must be compared with a long list of unsolved problems, above all where non-contact measurement is concerned. The attempts at solutions are multifarious, the need for the exchange of experience is great and the comparson of measurement processes with one another must be strengthened.

The workshop has set itself these targets. Entsprechend gross sind die Wuensche der Experimentatoren hinsichtlich der Messtechnik: Neben den klassischen Parametern Druck, Temperatur und Stroemungsgeschwindigkeit wird eine moeglichst hoch aufloesende Erfassung der momentanen Phasenverteilung benoetigt.

Ausserdem bestehen die Phasen selbst haeufig aus mehreren Komponenten, deren Konzentration ebenfalls gemessen werden soll. Den enormen Fortschritten, ie mit laseroptischen und tomographischen Verfahren in letzter Zeit gemacht wurden, steht nach wie vor eine lange Liste bisher ungeloester Aufgaben gegenueber, vor allen Dingen, wenn beruehrungslos gemessen werden soll.

Die Loesungsansaetze sind vielfaeltig, der Bedarf an Erfahrungsaustausch ist gross, der Vergleich der Messverfahren untereinander muss verstaerkt werden. Annual report ; Bundesanstalt fuer Strahlenschutz. Development of segmented germanium detectors for neutrinoless double beta decay experiments. The results from neutrino oscillation experiments indicate that at least two neutrinos have mass. However, the value of the masses and whether neutrinos and anti-neutrinos are identical, i.

Neutrinoless double beta decay experiments can help to improve our understanding in both cases and are the only method currently possible to tackle the second question. In order to achieve an extremely low background level, segmented germanium detectors are considered to be operated directly in liquid argon which serves simultaneously as cooling and shielding medium. Several test cryostats were built at the Max-Planck-Institut fuer Physik in Muenchen to operate segmented germanium detectors both in vacuum and submerged in cryogenic liquid.

The performance and the background discrimination power of segmented germanium detectors were studied in detail. It was proven for the first time that segmented germanium detectors can be operated stably over long periods submerged in a cryogenic liquid. It was confirmed that the segmentation scheme employed does well in the identification of photon induced background and demonstrated for the first time that also neutron interactions can be identified.

It is based on GEANT4, but tailored especially to simulate the response of ultra-low background detectors to ionizing radiation. The predictions of the simulation were veri ed to be accurate for a wide range of conditions. Some shortcomings were found and corrected. Pulse shape analysis is complementary to segmentation in identifying background events. Its efficiency can only be correctly determined using reliable pulse shape. Its efficiency can only be correctly determined using reliable pulse. Bundesamt fuer Strahlenschutz.

The progress report submitted by Bundesamt fuer Strahlenschutz reveals that this federal radiation protection agency is not only entrusted with the fulfillment of the federal administrative tasks imposed by law but engages in applications-oriented research regarding the operational, metrological and health-related aspects of radiation protection, regarding nuclear safety and radioactive waste management.

In addition, BfS takes care of public-relations tasks. The reports submitted by the BfS departments are completed by summaries of the main research results.

Spectroscopic studies on technetium and silicon. A solid-state laser system for the resonance-ionization spectroscopy; Spektroskopische Untersuchungen an Technetium und Silizium. Ein Festkoerperlasersystem fuer die Resonanzionisationsspektroskopie. This doctoral thesis describes advancement and refinement of the titanium:sapphire laser system of the working group LARISSA, Institut fuer Physik , Johannes Gutenberg- Universitaet Mainz and its application to resonance ionization spectroscopy.

Activities on the laser systems comprised three major tasks: The output power of the conventional titanium:sapphire lasers could be increased by a factor of two in order to match the needs at resonance ionization laser ion source at ISOL facilities. Additionally, the laser system was complemented by a titanium:sapphire laser in Littrow geometry, which ensures a mode-hop free tuning range from nm to nm, and by an injection seeded titanium:sapphire laser with a spectral width of 20 MHz in respect to a spectral width of 3 GHz for the conventional lasers.

The performance of the new laser system was tested in spectroscopic investigations of highly excited atomic levels of gold and technetium. From the measured level positions the ionization potential of gold could be verified by using the Rydberg-Ritz formula, while the ionization potential of technetium could be determined precisely for the first time. Using the seeded titanium: sapphire laser Doppler-free two-photon spectroscopy inside a hot ionizer cavity was demonstrated. A width of the recorded resonances of 90 MHz was achieved and the hyperfine structure and isotope shift of stable silicon isotopes was well resolved with this method.

List of Participants. Some applications of nanometer scale structures for current and future X-ray space research. Nanometer scale structures such as multilayers, gratings and natural crystals are playing an increasing role in spectroscopic applications for X-ray astrophysics.

A few examples are briefly described as an introduction to current and planned applications pursued at the Danish Space Research Livermore National Laboratory. These examples include : 1. Continuum of quanta in the final theory. Model of spiral fields. Basic ideas for a compatible physics and a consistent nature science. Grundgedanken fuer eine Kompatible Physik und eine Konsistente Naturwissenschaft. The internationally favored direction of the physics sciences looks for the solution of the basic problems in higher and higher energies at impressive research constructions - mockingly mentioned as 'cognition machines' - which surpass itself with its financial efforts each the other.

If in this wise shall be found: 'The elementariest bit of all elements' and 'the unity of the whole physics as well as the whole nature sciences at all', then this is a thought aberration. The prognosticated HIGGS-particles may have an exceptional quality; however, they would be very complex objects which integrate an enormous number of effect-quanta h Planck constants in their structure: They are with safety not simplicity.

They will also not bring a better understanding about the simplicity of the last elements for us. We know since Planck, Poincare, Einstein, Bohr, Heisenberg, Schroedinger, DeBrogue and other well-known physicists that the 'atomos' can have only a diminutiveness discrete not measurable energy. The search with gigantic machines is at all especially nonsensical than it pumps still energy into the processes.

However, the elementary consists of fractions from that energy what have well-known smallest particles or weakest radiation in itself puts. The work in hand follows another approach. It grasps nature on a deductive way. I start out from a most general analysis and synthesis of scientific and everyday-language concepts; and I combine that with a principle of 'general physical field' which after Einstein must exist. The dynamic space-time processes of the fields are depicted by graphic means in mathematical spatial coordinate-systems.

Through it arises a consistent view over all areas of the knowledge from the most simply over simple structures until to the most complicated phenomena and things: that one are the cognition remained secretive till now obstinately. In the foreground will be originate as important the solution of the puzzle around the 'Dualism of Waves and Particles'. Structures of matter do not consist of any a priori, i. The circulation in itself creates locality; without that the radiation lost their dynamics; and without that this radiation must itself change into electrons: with their secondary turn in the orbital path.

Classic Physics and the Quantum Physics merge in a Model of Spiral Fields into a paramount thought building with a new imagination for radiation and particles. Molecules, atoms and seedless particles have to be analyzed on the new basis. The rich fundus of proven knowledge will help. Problems of the natural sciences which do not find any immediate explanation should be taken in relation to the new thoughts; therewith will the special aspects visible.

A single human is not able to it in view of the gigantic range of the accumulated knowledge. Physics for all, who want to join in conversation. On atomic power, dirty bombs, space research, solar energy, and the global heating; Physik fuer alle, die mitreden wollen. Which dangers contains the global heating really? What can happen at an attack on a atomic power plant?. Which chances offer renewable energies? Questions which are put daily in the pursuing of news - but to which we have only seldomly answers ready, because basic physical knowledge is absent.

But it must not even be the great world policy. Already at the decision wether solar cells shall be mounted on the roof or punted on geothermal heat physics are not unimportant. More often than we think it are natural sciences, which yield the foundations for important decisions.

Richard A. Muller explains simply and illustratively, how physics determines our life. Thereby he removes prejudices and mediates quite surprising insights. Subjects: Central services; Air pollution abatement; Noise and vibration protection; Protection against non-ionising radiation; Waste management, land pollution and soil protection; Nuclear power and radiation protection; Conservation and landscaping; Central technical issues.

The tasks of the Landesamt are illustrated by practical examples. Dabei werden anhand von konkreten Beispielen die Aufgaben des Landesamtes erlaeutert. Becker, B. This new report, on the one hand, takes into consideration the role of the organizational IP unit as one offering its services to all sections of a company.

Introduction

On the other hand, information processing as an operational infrastructure influencing all business processes becomes increasingly important with respect to the competitiveness of the EVU. Therefore, quality management applied to IP projects and IP services must support this development. Zum anderen gewinnt die Informationsverarbeitung als betriebliche Infrastruktur fuer alle Geschaeftsprozesse zunehmende Bedeutung fuer die Wettbewerbsfaehigkeit der EVU. Perspectives of a fusion power plant.

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. 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.

The electron cyclotron resonance heating system for the W7-X stellarator is a joint effort of the Max-Planck-Institut fuer Plasmaphysik in Greifswald, the Institut fuer Plasmaforschung Stuttgart and the Forschungszentrum Karlsruhe under the supervision of the latter. Currently it is being constructed at the Greifswald branch of IPP. It will consist of 10 gyrotrons each with 1 MW GHz in the CW regime and a quasi optical multi-beam transmission line. The prototype phase of the gyrotrons is almost over and significant results have been achieved. The manufacturing of the transmission line is ongoing.

An overview over the system including data acquisition and control issues will be given and the current status of the construction will be presented. Clean air litigation; Klagen fuer Saubere Luft.

Enhanced Schottky signals from electron-cooled, coasting beams in a heavy-ion storage ring.

Krantz, C. Measurements at the Test Storage Ring of the Max-Planck-Institut fuer Kernphysik in Heidelberg Germany have shown that the signal amplitude induced in a Schottky-noise pickup electrode by a coasting electron-cooled ion beam can be greatly enhanced by exposure of the latter to a perturbing radiofrequency signal which is detuned from the true beam revolution frequency. The centre frequencies obtained from harmonic analysis of the observed pickup signal closely follow those imposed on the ions by the electron cooling force.

The phenomenon can be exploited to measure the true revolution frequency of ion beams of very low intensity, whose pure Schottky noise is too weak to be measurable under normal circumstances. On coupling global biome models with climate models. It is found that incorporation of the BIOME model into ECHAM, regardless at which frequency, does not enhance the simulated climate variability, expressed in terms of differences between global vegetation patterns.

Strongest changes are seen only between the initial biome distribution and the biome distribution computed after the first simulation period, provided that the climate-biome model is started from a biome distribution that resembles the present-day distribution. After the first simulation period, there is no significant shrinking, expanding, or shifting of biomes. Likewise, no trend is seen in global averages of land-surface parameters and climate variables. A global data set of land-surface parameters. The global set of surface parameters is constructed by allocating parameters to major exosystem complexes of Olson et al.

The global distribution of ecosystem complexes is given at a resolution of 0. Rapid variability of extragalactic radio sources. Since its discovery more than 20 years ago, variability of extragalactic radio sources on timescales of weeks to years has been the subject of many investigations. We have examined the variability of these sources on timescales of hours at wavelengths of 6 and 11 cm using the m telescope of the Max-Planck-Institut fuer Radioastronomie and report the results for two sources.

We discuss intrinsic effects, gravitational lensing and scattering in the interstellar medium as possible explanations for rapid radio variability. Orlov, D. The ring will operate in a broad temperature range from 2 to K and is required to be bakeable up to K. Extremely high vacuum and low temperatures are necessary to achieve long lifetimes of the molecular ions stored in the ring so that the ions will have enough time to cool by radiation to their vibrational and rotational ground states.

To test cryogenic and vacuum technological aspects of the CSR, a prototype is being built and will be connected to the commercial cryogenic refrigerator recently installed, including a specialized 2-K connection system. The first results and the status of current work with the prototype are also presented. Current disruption in toroidal devices. Attempts at raising the density or the plasma current in a tokamak above certain critical values generally result in termination of the discharge by a disruption.

This sudden end of the plasma current and plasma confinement is accompanied by large induced voltages and currents in the outer structures which, in large tokamaks, can only be handled with considerable effort, and which will probably only be tolerable in reactors as rare accidents. Because of its crucial importance for the construction and operation of tokamaks, this phenomenon and its theoretical interpretation were the subject of a three-day symposium organized by the International Atomic Energy Agency and Max-Planck-Institut fuer Plasmaphysik at Garching from February 14 to Pleading for a rational energy policy; Fuer eine aufgeklaerte Energiepolitik.

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.

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. 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.

Meteorological systems for hydrological applications; Meteorologische Systeme fuer hydrologische Anwendungen. 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. Wo ueberall sich ein Bedarf an meteorologischen Daten in Hydrologie und Wasserwirtschaft eingestellt hat, ist in diesem Bericht zusammengefasst. Es werden die verschiedenen Messnetze und Messverfahren beschrieben und kritisch beurteilt, auch die Radar- und Satellitenfernerkundung gehoeren dazu.

Fuer den Hydrologen zaehlt zu den wichtigsten abgeleiteten Groessen der Gebietsniederschlag und die Gebietsverdunstung, jeweils mit Angabe von Fehlerquelle und Fehlerschwankung. Von Interesse sind auch die Schneeschmelze, der vermutlich maximale Niederschlag Regen , die statistische Ableitung von Starkregen und Regionalisierungsmethoden aller abgeleiteten Groessen.

Diese Verfahren werden vorgestellt. Die quantitative Niederschlagsvorhersage wird wegen ihrer Bedeutung fuer die operationellen hydrologischen Vorhersagen eingehend. Technology for the future; Technik fuer die Zukunft. 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. Im Winter wird eine Batterie in Deutschland aufgrund der niedrigen Sonneneinstrahlung nicht immer komplett geladen.

Fuer mehr Vollzyklen im Jahr und demzufolge geringere spezifische Speicherkosten koennen Windkraftanlagen oder andere Stromerzeuger angeschlossen werden. Bundesamt fuer Strahlenschutz BfS.

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. Die Solarisierung von Bebauungsplaenen beeinflusste Anordnung der Gebaeude hinsichtlich der Nutzung passivsolarer Gewinne sowie des Einsatzes von Systemen der aktiven Solarenergienutzung. Solarunterstuetzte Nahwaermenetze fuer Wohnsiedlungen werden ebenfalls beschrieben.

Jahrbuch fuer Gebaeudetechnik The HVAC engineering yearbook contains contributions on energy conservation and optimization in the fields of ventilation and air conditioning: inter alia, solar cooling and air conditioning, optimum rating of ventilator units, and cooling ceilings with ventilation function.

In the field of heating, the following topics are addressed, equally under the aspect of energy conservation: condensing boiler technology, hydraulic balancing of heating pipe systems and sequential boiler switching using fuzzy control. Further works deal with rational use of electricity in buildings, and building automation. Auf dem Gebiet der Heizung werden ebenfalls unter dem Gesichtspunkt Energieeinsparung die Brennwerttechnologie, der hydraulische Abgleich von Heizungsrohrnetzen sowie Kesselfolgeschaltungen mit Fuzzy Control angesprochen. Weitere Arbeiten befassen sich mit der rationellen Elektrizitaetsverwendung in Geb auden sowie der Gebaeudeautomation.

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. Ziel ist es, Innovationen zu ermoeglichen, aber auch Risiken fruehzeitig zu erkennen und zu mindern.

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. 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. Parameters for viable process combinations; Randbedingungen fuer sinnvolle Verfahrenskombinationen. The following parameters merit examination in determining the viability of process combinations: conceptual and technical soundness, environmental acceptability, energy balance, flexibility, costs, economic risk potential.

The present contribution on this subject is not intended to take the place of or cover the scope of single-case studies. In practice, viability studies on process combinations have to deal with concrete plans involving precisely defined material flow balances, emissions, costs etc. The present paper therefore only presents the basic principles of this type of study. Nun kann dieser Beitrag zum Thema keine Einzelfallbetrachtung ersetzen bzw. Im Rahmen dieser Betrachtung koennen nur die Grundzuege einer derartigen Pruefung dargestellt werden. Ageing management of mechanical components; Alterungsmanagement fuer mechanische Komponenten.

Hienstorfer, W. Stuttgart, Stuttgart Germany. Lifetime management, ageing management and integrity testing are part of technical rules and specifications.

Fibre-reinforced ceramics for vehicle brakes; Faserverstaerkte Keramiken fuer Bremsenanwendungen. Krenkel, W.

General relativity and the growth of a sub-discipline “gravitation” in Germany | SpringerLink

Fibre-reinforced ceramics are extremely light, with a high fracture toughness, and have a high potential for applications in motor brakes. 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. Diese extrem leichten und bruchzaehen Faserkeramiken haben sich unter den besonderen Bedingungen des Weltraums beispielsweise fuer Hitzeschutzstrukturen von Raumfahrzeugen hervorragend bewaehrt.

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. Die Leistungsfaehigkeit heutiger Bremssysteme kann damit deutlich gesteigert und die ungefederte Masse des Fahrwerks drastisch reduziert werden. Mit der zielgerichteten Anpassung geeigneter Belaege auf die neuen Keramik-Bremsscheiben scheint erstmals ein Einsatz von Lebensdauerbremsen moeglich zu sein, deren geringe Verschleissraten einen Austausch der Bremsscheiben waehrend der Betriebszeit eines Fahrzeugs ueberfluessig machen.

Neben der Verwendung dieser innovativen Leichtbaubremsen im PKW-Bereich wird zukuenftig deren Einsatz auch fuer Gefahrguttransporter, Hochgeschwindigkeitszuege, Flugzeuge und fuer Sicherheitsbremsen im Maschinen- und Anlagenbau sowie in der Foerdertechnik erwartet. QGM Research Report. I outlined my joint work with Camilo Arias Abad Max Planck Institute , Bonn on higher holonomies for flat superconnections and explained some background material 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.

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. The project has been coordinated by the Institute for Environmental Questions ''Unabhaengige Institut fuer Umweltfragen e.

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.
