    VomsSnooper is a tool to keep documents and sites up to date with the newest VOMS records, removing the need for manual edits to security configuration files. The input data is administered centrally at the Operations Portal, and it is made available in XML format. Prior to VomsSnooper, it was necessary at each site to manually convert the XML data. VomsSnooper automates this process by checking and creating new VOMS records directly from the portal, providing a bridge between the Operations Portal and the site configuration. The tool is also used to publish online the VOMS data of thirty Approved VOs in the GridPP wiki.

    The Grid community uses two well-established registration services, which allow users to be authenticated under the auspices of Virtual Organizations (VOs). The Virtual Organization Membership Service (VOMS), developed in the context of the Enabling Grid for E-sciencE (EGEE) project, is an Attribute Authority service that issues attributes expressing membership information of a subject within a VO. VOMS allows to partition users in groups, assign them roles and free-form attributes which are then used to drive authorization decisions. The VOMS administrative application, VOMS-Admin, manages and populates the VOMS database with membership information. The Virtual Organization Management Registration Service (VOMRS), developed at Fermilab, extends the basic registration and management functionalities present in VOMS-Admin. It implements a registration workflow that requires VO usage policy acceptance and membership approval by administrators. VOMRS supports management of multiple grid certificates, and handling users' request for group and role assignments, and membership status. VOMRS is capable of interfacing to local systems with personnel information (e.g. the CERN Human Resource Database) and of pulling relevant member information from them. VOMRS synchronizes the relevant subset of information with VOMS. The recent development of new features in VOMS-Admin raises the possibility of rationalizing the support and converging on a single solution by continuing and extending existing collaborations between EGEE and OSG. Such strategy is supported by WLCG, OSG, US CMS, US Atlas, and other stakeholders worldwide. In this paper, we will analyze features in use by major experiments and the use cases for registration addressed by the mature single solution.

    The Directive 2001/80/EC of the European Parliament and of the Council, on the limitation of emissions of certain pollutants into the air from large combustion plants uses a regulatory instrument for limiting emissions at the national levels of EU member states. This approach is completely new and the author of this article therefore expects problems to arise in the context of transfer of this EC Directive into national law. Another aspect discussed is the assessment of implications for the operating power plants in Germany. (orig./CB) [German] Mit der im Herbst 2001 durch das Europaeische Parlament und durch den Umweltministerrat verabschiedeten Richtlinie ueber nationale Emissionshoechstmengen wurde vom europaeischen Vorschriftengeber ein in Deutschland bislang systemfremdes Regelungsinstrument geschaffen, dessen Umsetzung in nationales Recht und dessen anlagenspezifische Konsequenzen - zumindest hierzulande -bislang noch reichlich unklar sind.

    The Vestibular/Ocular Motor Screening (VOMS) measure is a newly developed vestibular and ocular motor symptom provocation screening tool for sport-related concussions. Baseline data, psychometric properties, and reliability of the VOMS are needed to further understand the applications of this tool, especially in the youth population, where research is scarce. To establish normative data and document the internal consistency and false-positive rate of the VOMS in a sample of nonconcussed youth athletes. Cross-sectional study; Level of evidence, 3. A total of 423 youth athletes (male = 278, female = 145) between the ages of 8 and 14 years completed baseline VOMS screening before the start of their respective sport seasons. Internal consistency was measured with Cronbach α and inter-item correlations. Approximately 60% of youth athletes reported no symptom provocation on baseline VOMS assessment, with 9% to 13% scoring over the cutoff levels (score of ≥2 for any individual VOMS symptom, near point convergence distance of ≥5 cm). The VOMS displayed a high internal consistency (Cronbach α = .97) at baseline among youth athletes. The current findings provide preliminary support for the implementation of VOMS baseline assessment into clinical practice, due to a high internal consistency, strong relationships between VOMS items, and a low false-positive rate at baseline in youth athletes.

    Background Vestibular and ocular motor impairments and symptoms have been documented in patients with sport-related concussions. However, there is no current brief clinical screen to assess and monitor these issues. Purpose To describe and provide initial data for the internal consistency and validity of a brief clinical screening tool for vestibular and ocular motor impairments and symptoms after sport-related concussions. Study Design Cross-sectional study; Level of evidence, 2. Methods Sixty-four patients, aged 13.9 ± 2.5 years and seen approximately 5.5 ± 4.0 days after a sport-related concussion, and 78 controls were administered the Vestibular/Ocular Motor Screening (VOMS) assessment, which included 5 domains: (1) smooth pursuit, (2) horizontal and vertical saccades, (3) near point of convergence (NPC) distance, (4) horizontal vestibular ocular reflex (VOR), and (5) visual motion sensitivity (VMS). Participants were also administered the Post-Concussion Symptom Scale (PCSS). Results Sixty-one percent of patients reported symptom provocation after at least 1 VOMS item. All VOMS items were positively correlated to the PCSS total symptom score. The VOR (odds ratio [OR], 3.89; P concussed group. An NPC distance ≥5 cm and any VOMS item symptom score ≥2 resulted in an increase in the probability of correctly identifying concussed patients of 38% and 50%, respectively. Receiver operating characteristic curves supported a model including the VOR, VMS, NPC distance, and ln(age) that resulted in a high predicted probability (area under the curve = 0.89) for identifying concussed patients. Conclusion The VOMS demonstrated internal consistency as well as sensitivity in identifying patients with concussions. The current findings provide preliminary support for the utility of the VOMS as a brief vestibular/ocular motor screen after sport-related concussions. The VOMS may augment current assessment tools and may serve as a single component of a comprehensive approach

    For the development and testing of ABS/ESP control units, both the detailed simulation of the vehicle and drive train dynamics as well as the dynamic behaviour of the hydraulic system are important. The signals coming from the control unit that control the valves in the brake hydraulic system cause pressure changes in the brake system and thus affect the braking torque. In turn, the changes in the speed of the wheels are fed back to the control unit via sensors. The objective of an ABS control strategy is to prevent the wheels from locking during braking in order to ensure and maintain the steerability of the vehicle, while the ESP action also attempts to achieve a stabilization of the yawing motion by means of active braking. (orig.) [German] Fuer die Entwicklung und den Test von ABS/ESP-Steuergeraeten ist neben der detaillierten Simulation von Fahr- und Antriebsstrangdynamik auch das dynamische Verhalten des hydraulischen Systems wichtig. Die vom Steuergeraet kommenden Signale zur Ansteuerung der Ventile in der Bremshydraulik bewirken Druckaenderungen im Bremssystem und somit der Bremsmomente. Die Aenderungen der Raddrehzahlen werden wiederum ueber Sensoren dem Steuergeraet zurueckgemeldet. Ziel einer ABS-Regelstrategie ist das Verhindern des Blockierens der Raeder beim Bremsen, um die Lenkbarkeit des Fahrzeugs zu erhalten, waehrend bei einem ESP-Eingriff durch aktives Bremsen zusaetzlich eine Stabilisierung der Gierbewegung erfolgen soll, wie der folgende Beitrag von Tesis Dynaware zeigt.

    High-voltage DC transmission is a world-wide established technology for low-cost transmission of large amounts of electricity over long distances. Thanks to HVDC transmission, large amounts of electricity can now for the first time also be transmitted over long distances via ocean cable, something that cannot be done with AC power cables. HVDC transmission is independent of grid frequencies and can link grids of different frequency and different quality of frequency. Interconnected grids coupled via DC circuits can exploit additional technical and economic advantages such as mutual supply of power reserves, balancing of peak load, and modulation of active and reactive power. (orig.) [Deutsch] Die Hochspannungs-Gleichstromuebertragung (HGUe) ist eine weltweit etablierte Technik zur kostenguenstigen Uebertragung grosser elektrischer Leistungen ueber grosse Entfernungen.

    Virtual outcrop models (VOM) is becoming an important application in the analysis of geological structures due to the possibility of obtaining the geometry and in some cases kinematic aspects of analyzed structures in a tridimensional photorealistic space. These data are used to gain quantitative information on the deformational features which coupled with numeric models can assist in understands deformational processes. Old basement units commonly register superposed deformational events either ductile or ruptile along its evolution. The Porongos Belt, located at southern Brazil, have a complex deformational history registering at least five ductile and ruptile deformational events. In this study, we presents a structural analysis of a quarry in the Porongos Belt, coupling field and VOM structural information to understand process involved in the last two deformational events. Field information was acquired using traditional structural methods for analysis of ruptile structures, such as the descriptions, drawings, acquisition of orientation vectors and kinematic analysis. VOM was created from the image-based modeling method through photogrammetric data acquisition and orthorectification. Photogrammetric data acquisition was acquired using Sony a3500 camera and a total of 128 photographs were taken from ca. 10-20 m from the outcrop in different orientations. Thirty two control point coordinates were acquired using a combination of RTK dGPS surveying and total station work, providing a precision of few millimeters for x, y and z. Photographs were imported into the Photo Scan software to create a 3D dense point cloud from structure from-motion algorithm, which were triangulated and textured to generate the VOM. VOM was georreferenced (oriented and scaled) using the ground control points, and later analyzed in OpenPlot software to extract structural information. Data was imported in Wintensor software to obtain tensor orientations, and Move software to process and

    Transition from power generation to decommissioning challenges utilities. Power generation is mainly characterized by a stable working environment and constant workload, decommissioning and dismantling, however, by transformation and change. Also, changing requirements for the workforce's skills challenge the organization and its senior management. Ensuring effective and efficient performance, while maintaining motivation of staff, requires adjustment of management processes as well as of operational organization and human resources management. AREVA has more than 20 years of experience in decommissioning of own nuclear fuel cycle plants in France, as well as of other large plants and power reactors in Germany, the United Kingdom and the US. Therefore, the group has developed and successfully implemented integrated change management processes. The implementation of well-established and proven methods, developed by the productive industry and adjusted to the nuclear regulatory requirements, significantly improves the performance and efficiency of means and methods in use. The AREVA Performance Improvement Process defines concrete approaches to identify and improve potential deficits of productivity in six main areas (decommissioning scenarios and stra-tegies, waste treatment and logistics, operations management, supply chain, regulatory monitoring and controls as well as dismantling operation). Nuclear plant and facility owners around the world benefit from AREVA experts well experienced in execution of large and complex decommissioning projects.

    More than 500 mining lakes of different age and maturity have formed in the lignite mining areas in Germany during the last hundred years. Compared to natural lakes mining lakes have a complex and diverse morphometry. They will be among the largest and deepest lakes in Germany (Hambacher See, Goitsche, Garzweiler II, Geiseltal) and have good chance of avoiding eutrophication. About 100 mining lakes will be greater than 50 ha. 230 lakes are documented in this report concerning morphometry, flooding and mixis regime, hydrochemistry, limnology, colonization, use and development of water quality. They are among the largest (Hambacher See, Goitsche, Garzweiler II, Geiseltal) and most acidic lakes in Germany. The extremely high acidity is from both iron and hydrogen ions due to pyrit oxidation. It influences trophic situation and food webs in mining lakes and reduces a diverse use of these lakes. (orig.) [German] Die Seelandschaft Deutschlands wird durch den Braunkohlenbergbau um ueber 500 Seen reicher. Technologiebedingt herrscht dabei eine grosse morphologische Vielfalt innerhalb der Tagebauseen vor, welche die groessten und tiefsten Seen Deutschlands hervorbringen wird (Hambacher See, Goitsche, Garzweiler II, Geiseltal), aber auch zahlreiche kleine, meist flachere Gewaesser miteinschliesst. Etwa 100 Taugebauseen sind groesser als 50 ha. Kleinere Tagebauseen wie z.B. die der Ville in Nordrhein-Westfalen wurden ebenfalls ausfuehrlich dokumentiert. In dieser Dokumentation wurden ueber 490 Seen erfasst, 230 davon wurden in der Dokumentation nach folgenden Kriterien beschrieben: Entstehung, Flutungsregime, Morphometrie und Mixis, Chemismus und Gewaesserentwicklung, Besiedlung und Nutzung. Dem Problem der Versauerung durch die Verwitterung sulfidischer Mineralien (Pyrit, Markasit) wurde besondere Aufmerksamkeit gewidmet, weil sich biologische Komponenten und Gewaesserzustaende (Trophie, Nahrungsketten) abweichend zu den normalen Hartwasserseen Deutschlands verhalten und

    Material development and blanket design of lithium-based ceramics such as lithium oxide, lithium aluminate, lithium silicate and lithium zirconate have been performed in Japan, United State of America and Europian Communities. Lithium oxide is a most attractive candidate for tritium breeding materials because of its high lithium density, high thermal conductivity and good tritium release performance. This work has been done to clarify the characteristics of tritium release and recovery from Li 2 O by means of in-situ tritium release measurement. The effects of temperature and sweep gas composition on the tritium release were investigated in this VOM-21H Experiment. Good measurement of tritium release was achieved but there were uncertainties in reproduciblity of data. The experimental results show that the role of surface adsorption/desorption makes a significant contribution to the tritium release and tritium inventory. Also, it is necessary to define the rate limiting process either diffusion or surface adsorption/desorption. (author)

    Five samples each were collected from the apple orchards in Lamingo dam and Vom area of Jos East and Jos South local government areas respectively. The samples were allowed to decay for three weeks to ensure efficiency in acquiring the radionuclides. The samples were analyzed using Gamma Ray spectroscopy. Barium- 204 with gamma activity energy level 1765.50keV was used to check the presence of Uranium-235 in the samples. The results showed that samples Lams 2,3,4 and Voms 1,4,5 had high gamma activity energy levels of 2436.356keV, l837.24keV 2928.37 keV and 1656.32keV, 1635.48keV, 2351.87keV respectively as compared to ( 204 B). While Lams 1,5 and Voms 2,3 had relatively lower gamma activity energy levels of 1325.23KeV, 1272.73keV and 1462.61KeV, 1183.24keV respectively. The samples with high gamma activity energy levels imply that radionuclide in the form of 235 U is present in trace amounts in the sampled areas. This can affect the output of apples cultivated in such areas as the chemical composition or structure of plants will be altered.

    The deregulation of the energy markets has given rise to sustained motion in the prevailing structures and market conditions of the supply industry. Dramatic declines in profits in the electricity sector have, in many companies, prompted reflex-like cost reduction programs which, however, frequently prejudice long-term growth prospects and viable future structures in favour of the results of the next fiscal year. The danger of sacrificing all flexibility and therefore market perspectives by corporate anorexia nervosa is immense. The MVV Energie AG, Mannheim, has reacted speedily to this situation and is pursuing a growth-oriented strategy which regards the challenges of competition as opportunity for on-going development.

    Full Text Available The recent study about the history of what is today the federal state of Rheinland-Pfalz (Rhineland- Palatinate: „Vom Scheitern der Demokratie – Die Pfalz am Ende der Weimarer Republik“ has recently been reviewed by Yves V. Grossmann. Beginning with the world economic crisis in October 1929 and ending with Hitlers rise to power in 1933, co-publisher Hannes Ziegler approaches the contemporary time in the Rhinland-Palatinate region, which was marked by political instability and economic disaster. The time of crisis during the Weimar years advantaged the political rise of the Nazis, allowing the NSDAP to become a mass-party in the Pfalz-region. This historical rise to power is approached via twelve different articles, each of them looking at the named topic from a different angle. The volume also explicitly deals with the time of French occupation, the economic-crisis and the political radicalisation. The media history and the press are also included. The political landscape, the church, the law system, and the branch of cultural life, which thrived regardless of the crisis, are also being adressed throughout the regional-historicalthemed volume. The review offers a short and comprehensive summary of the book's contents. The classification and evaluation of the volume furthermore arrive at a thoroughly positive conclusion.

    Full Text Available Zur Klaerung der Frage, ob der Begriff "Kinoplasma" fuer gewisse, von MERTON (1924,1926, 1930 beobachtete Bildungen an den reifenden Spermiden von pulmonaten Mollusken oder fuer Bestandteile des Cytoplasmas im Sinne von STRASBURGER und SCARTH zu verwenden ist, werden in der vorliegenden Mitteilung die Vorgaenge bei der Spermiohistogenese von Australorbis glabratus olivaceus untersucht. Es ergibt sich: 1. Das von MERTON bezeichnete "Kinoplasma" existiert nicht als solches, es handelt sich bei den von ihm dargestellten Protoplasmabildungen um kugelige, von den Spermiden abgeschnuerte Restkoerper nicht verwendeten Baumaterials, bestehend aus Protoplasma und einigen Mitochondrien. Sie werden von den Naehr- oder Bazalzellen phagozytiert. Der Ausdruck "Kinoplasma" kann nur fuer die submikroskopischen, geformten, faedigen Elemente des Cytoplasmas reserviert bleiben, die den geradlinigen Fall der uebrigen nicht geformten Komponenten bremst oder ablenkt; damit muss das Kinoplasma aber aus dem Begriff des Cytoplasmas herausgenommen werden, da es, wenn auch vermutlich reversibel, eine Differenzierung darstellt. 2. Der Spermienfaden wird von den Centriolen (Axialfilament und den Mitochondrien (zwei peripher gelegene Spiralfilamente, sowie einem Plasmamantel gebildet. 3. Nach Beendigung des Auswachsens der Spermiengeissel, die zu diesem Zeitpunkt nur aus dem Achsenfaden und dem Protoplasmazylinder besteht, setzt sich eine Protoplasmamasse vom Kopf in Richtung zum Geisselende in Bewegung. Sie fuehrt den Golgi-Koerper und sehr viele Mitochondrien mit sich. Aus diesen entwickeln sich Fibrillen, die sich zu den beiden Spiralfilamenten zusammenfuegen.

    The harnessing and enhanced use of renewable energy today is a matter of lively debate and much concern. Amazingly, hydro power is either rarely considered in these discussions or viewed in a negative light. But hydro power continues to be the most important source of renewable energy, and its use potential is considerable and should be taken into account when, for instance, agreeing on or implementing carbon dioxide reduction targets. Small hydro power stations are an effective means of harnessing existing energy potentials. (orig.) [Deutsch] Ueber die Nutzung und den Ausbau regenerativer Energien wird heutzutage lebhaft diskutiert und gerungen. Es mag erstaunen, dass in diesen Diskussionen die Wasserkraft kaum Beachtung findet oder in einem schlechten Licht gesehen wird. Dabei ist die Wasserkraft nach wie vor bei weitem die wichtigsten Quelle regenerativer Energie, und sie besitzt ein beachtliches Ausbaupotential, das man wenigstens ins Kalkuel ziehen sollte, wenn es etwa darum geht, CO{sub 2}-Minderungsziele zu vereinbaren bzw. anzustreben. Die Kleinwasserkraft kann hier als Chance gesehen werden, noch vorhandene Energiepotentiale sinnvoll zu nutzen. (orig.)

    Full Text Available This paper elaborates a theme at the interface between linguistics and literature on the case example of a novel which belongs to the immigrant literature as part of the contemporary Austrian literature. The Croatian author Ana Bilic describes in her first novel written in German language Das kleine Stück vom großen Himmel (The small part of the big sky published in 2002 the love relationship between a Croatian unnamed female student and the Austrian student Ernst which takes place in Vienna. The unusual thing in this novel is the fact that in numerous sentences and passages the author uses a strange German language which is characterized by interference mistakes, or to be precise a Croatian-German language variation which more or less differs grammatically and lexically from standard German language. In the paper this consciously alienated language is being investigated concerning the influence of the Croatian mother tongue of the author, but also concerning common mistakes while learning German language. The paper also analyses the motivation of Ana Bilic for such in the context of immigrant literature unusual language use, which is also connected with the plot of the novel. Thus qualitative as well as quantitative methods of analysis are being used, whereby the former ones refer to the content and the latter ones to the frequency of interference mistakes in the book. The interference mistakes belong on one side to the fictional (text-internal world and on the other side to the factual (text-external level, because they reflect the plot of the book and establish on the level of content and language a connection between the first-person narrator and the author, who also had to learn German after her arrival to Vienna. As a result of this most interference mistakes appear in the first chapters of the novel, which reflects the first phase in German language learning of the female narrator. Further on in the novel the quantity of the mistakes

An intelligent provocation worthwhile to be read and discussed. Some main topics drawn from content: Atom - Germans' favourite fear; big thirst for oil; Germany - yours coal; myth sun; atoms for peace and fission for climate. (GL) [German] Energie ist das Schluesselthema der Zukunft. Die wesentlichen weltpolitischen Auseinandersetzungen werden sich an Fragen der Energieversorgung entzuenden.

Wir muessen einsehen, dass wir den Traum vom Atomausstieg verabschieden muessen. Dennoch macht sich Rubner in diesem Buch nicht zum Sprachrohr der Atomlobby. Ihr geht es vielmehr um eine realistische Beurteilung einer zukunftstraechtigen Energiepolitik. Die Dramatik des Buches besteht nicht zuletzt darin, dass sich die Autorin - gegen ihre politischen Wuensche und Hoffnungen - zu einer Revision der eigenen Position gezwungen sieht.

    The number of jobs in the field of renewable energy sources is disproportionately high as compared to conventional energy sources. For example, the German wind industry has 30,000 jobs for a 3% share in power supply. According to the White Book on Renewable Energy Sources of the European Commission, the share of renewable energy sources is to be increased to 12% by 2010. This will mean 1.2 million new jobs. If the share is increased to 20%, 2 million new jobs will be created in the European Union according to an EUROSOLAR study. [German] Die erneuerbaren Energien haben im Verhaeltnis zu konventionellen Energietraegern ein ueberproportional hohes Arbeitsplatzangebot.

Das Weissbuch der Europaeischen Kommission ueber erneuerbare Energien hat das Ziel formuliert, den Anteil der erneuerbaren Energien bis zum Jahr 2010 auf 12 Prozent zu steigern. Die Europaeische Kommission sieht damit die Schaffung von 1,2 Millionen Arbeitsplaetzen verbunden. Wenn der Anteil der erneuerbaren Energien in der Europaeischen Union auf 20 Prozent erhoeht wird, werden gemaess einer EUROSOLAR - Studie in der EU sogar 2 Millionen neue Arbeitsplaetze entstehen.

    In the run-up to the Kyoto conference, there is far-reaching agreement that the world energy industry needs to be reconstructed by the middle of the next century if a climate catastrophe is to be avoided. But how this goal can be reached is controversial. The risks involved are described in contributions concerned with German energy policy, the insurance sector, and scenarios for mitigating carbon dioxides on the basis of the Ikarus model. But the focus of this annual report of DPG`s task force Energy is on reports on longer-term technologies and methods. Two papers describe the state of the art of fusion research. In the conventional energy sector, high-efficiency absorption-type refrigerators and thermal engines, and fuel conservation through low-cost passive architecture are dealt with inter alia. Other lectures report on the state of solar energy utilization and process chains in the hydrogen-based economy. Five papers are individually listed in the Energy database. (orig.) [Deutsch] Im Vorfeld der Konferenz von Kyoto besteht weitgehende Einigkeit, dass die Weltenergiewirtschaft bis zur Mitte des naechsten Jahrhunderts umgestaltet werden muss, um eine Klimakatastrophe zu verhindern.

    Full Text Available El funcionamiento del ojo compuesto del insecto es totalmente distinto del del ojo sencillo.  Con el ojo compuesto cualquier movimiento en el espacio -desde el momento en que se encuentra dentro de la esfera visual- puede ser interpretado correcta y unívocamente. Ello demuestra y comprueba que, en general el reconocimiento como juicio no ha de ser necesariamente una función de la razón humana.  El ojo compuesto divide lo percibido en partes muy pequeñas que se siguen automáticamente, obteniendo así un propio concepto del tiempo. Este permite (cualquiera que sea el movimiento en el espacio solucionar con la objetivación de la fórmula: tiempo por camino, el problema de alcanzar con seguridad un objeto que vuela rápidamente en el libre espacio.  La línea que describe el vuelo, sea tan curva como fuere, se proyecta sobre la superficie de los ommatidia, siendo transmitida de un ommatidium al otro, sucesivamente, a un centro visual.  Este centro visual dirige el propio vuelo de manera que el retrato del objeto permanece visible por un tiempo cada vez más largo en un siempre menor numero de ommatidia.  Esto significa, para el insecto cazador: la presa se mueve de acuerdo con su tiempo, es decir, cada vez más lento.  Si finalmente no queda visible sino en un solo ommatidium, la presa, aparece como inmóvil y así puede ser cogida. Resulta de lo anterior que el insecto cazador ha de moverse de tal manera que la línea de vuelo del objeto perseguido se proyecte en el ojo compuesto de su perseguidor en forma cada vez más rectangular.  El método visual automático garantiza una alimentación segura por la caza de presas pequeñas de vuelo rápido en el libre espacio.

    The BGH judgment deals with plaintiff's contractual and tortious claims relating to hospital X which carried out the operation, and hospital Y plaintiff was referred to by hospital X for the purpose of post-operative irradiation. In addition, it is examined whether there are claims against hospital Y, or its performing or vicarious personnel (contractual and tortious aspects), on account of claims resulting from breach of the duty to inform. Judgment does not deal with the question whether the charge of damage due to incorrect therapy applies (in lack of sufficient evidence in the judgment against which appeal was lodged) and with questions of the running out of the period of limitation.

    In hierarchical monitoring systems, normally only the main line can be checked automatically for rupture of the sensor wire. During the AGFW lecture conference in 1998 in Essen, a solution was introduced, where through closing the branch lines with endpieces by the Roetter Industrieelektronik GmbH, the branch lines could be also monitored for ruptures automatically. This process has been further developed since then and now offers the possibility to directly indicate the ruptured branch and if there is more than one rupture, this can be indicated separately as well. (orig.) [German] In hierarchischen Ueberwachungssystemen kann ueblicherweise nur die Hauptleitung automatisch auf Abriss des Sensordrahtes geprueft werden. Bereits auf der AGFW Vortragstagung 1998 in Essen wurde eine Loesung vorgestellt, durch Abschluss der Abzweigleitungen mit Endstuecken von Roetter Industrieelektronik GmbH auch die Abzweigleitungen automatisch auf Abriss zu ueberwachen. Dieses Verfahren wurde praxisgerecht weiterentwickelt und bietet nun die Moeglichkeit, den vom Abriss betroffenen Abzweig direkt anzuzeigen, bei mehreren Abrissen ist jeder einzelne zuzuordnen.

    This report, which relates the situation as of July 1997, again confirms the internationally leading role of the Federal German Republic in the phase-out of CFCs. No country has realised a more comprehensive concept for the phase-out of substances that deplete the ozone layer. Combining statutory and voluntary measures has proved a path-breaking approach. One of the most important driving forces in the CFC phase-out were the restrictions of use imposed by the Ordinance on the Prohibition of CFCs and Halon. (orig./SR) [Deutsch] Dieser Bericht - mit Stand vom Juli 1997 - bestaetigt erneut die internationale Fuehrungsrolle der Bundesrepublik Deutschland beim FCKW-Ausstieg.

Als wegweisend hat sich dabei die Verknuepfung ordnungsrechtlicher und freiwilliger Massnahem erwiesen. Insbesondere von den Verwendungsbeschraenkungen der FCKW-Halon-Verbots-Verordnung gingen wichtige Impulse beim FCKW-Ausstieg aus. (orig./SR)

Sie gilt daher als überkomplex und konnte bislang hochschuldidaktisch nicht systematisch transformiert wurden. Zur Rede stehen hier begriffliche Großprojekte wie Gerechtigkeit, Verantwortung, Partizipation, Retinität oder Globalität und Interkulturalität, die als Kristallisationspunkte der Nachhaltigkeitsidee die Grundlagentexte, Positionspapiere und Programme durchziehen. Im Anschluss an die heuristische Studie Globalität und Interkulturalität als integrale Bestandteile beruflicher Bildung für eine nachhaltige Entwicklung (GInE, www.ibw.uni-hamburg.de/GInE wurde ein didaktisches Strukturgitter entworfen, das exemplarische Problemlagen und Dilemmata benennt, so wie Reflexionskategorien für die Hochschuldidaktik in der beruflichen Lehrerbildung zur Diskussion stellt.As a regulative concept, the idea of sustainability implies a number of theorems in the field of humanities. It is regarded as supercomplex and, thus, could not yet be systematically transformed in university didactics. Large scale conceptual terms such as justice, responsibility, participation, retinity, globality, and interculturality are at the core of the discussion – terms which run through basic texts, policy papers, and programmes as focal points of the idea of sustainability. With respect to the heuristic study Globality and Interculturality as Integral Elements of a Professional Education for a Sustainable Development (GInE, www.ibw.uni-hamburg.de/GInE, a didactic framework was designed which not only denotes exemplary problems and dilemmata but also puts up categories of reflection for a university didactics aiming at a professional teacher training.

    radioaktive Abfaelle verantwortlich. Fruehzeitig mit der Inbetriebnahme der ersten Kernkraftwerke wurden in den 1960er Jahren entsprechende Schritte eingeleitet. Diese resultierten u.a. in den Beschluessen und Auswahlverfahren der 1970er und 1980er Jahre zum Salzstock Gorleben sowie zum ehemaligen Eisenerzbergwerk Konrad als potenzielle Endlagerstandorte. Die Bundesregierung hat im Jahr 2000 fuer Gorleben ein drei- bis maximal zehnjaehriges Moratorium fuer die weiteren Erkundungsarbeiten festgelegt, um aus Sicht des Bundesministeriums fuer Umwelt, Naturschutz und Reaktorsicherheit (BMU) bestehende Zweifel abzuarbeiten. Fuer Konrad wurde im Mai 2002 ein positiver Planfeststellungsbeschluss erteilt. Nach Erlangung der Rechtssicherheit koennte ab etwa 2010-2012 die Einlagerung beginnen. Im Februar 1999 wurde der Arbeitskreis Auswahlverfahren Endlagerstandorte (AkEnd) durch das BMU berufen. Der Auftrag bestand in der Entwicklung eines nachvollziehbaren Verfahrens fuer die Suche und die Auswahl von Standorten zur Endlagerung aller Arten radioaktiver Abfaelle in Deutschland. Das vom AkEnd abschliessende vorgestellte Verfahren birgt erhebliche Unsicherheiten, u.a. bezueglich der rechtlichen Umsetzbarkeit, des erforderlichen Zeitbedarfs und der Finanzierung. Es koennen sich mit Blick auf den Salzstock Gorleben allein durch zusaetzliche Erkundungen und Verfahren Mehrkosten gegenueber der Weiterfuehrung der Projekttaetigkeiten in Hoehe von 3 bis 5 Mrd. Euro ergeben. Aehnlich hohe Mehrbelastungen - insbesondere fuer die oeffentliche Hand - sind bei einer Verzoegerung der Einlagerung in Konrad zu erwarten. Eine moeglichst zuegige Endlagerung aller Abfallarten in tiefen geologischen Formationen ist unter sicherheitstechnischen Aspekten anderen Alternativen vorzuziehen. Daher sollte unter Beruecksichtigung aller Faktoren eine weitere Erkundung von Gorleben zuegig abgeschlossen und das Projekt Konrad realisiert werden. (orig.)

    besitzt eine Reihe von Vorteilen gegenueber klassischen ''trockenen'' Laserverfahren. Das urspruenglich auf reinem, deionisiertem Wasser als Strahlmedium aufbauende System wurde im Rahmen dieser Arbeit so modifiziert, dass der Fluessigkeitsstrahl nunmehr nicht nur als fluessiger Lichtleiter dient, sondern gleichzeitig auch als Transportmedium fuer Aetzmittel, welche den thermischen Abtrag des Siliziums durch den Laserstrahl unterstuetzen. Den praktischen Teil dieses Arbeitspaketes bildete der Test zweier Aetzmedien im Experiment. Dabei konnte gezeigt werden, dass wasserfreie Strahlmedien basierend auf perfluorierten Loesemitteln mit bereits sehr geringen Zusaetzen gasfoermigen Chlors als Aetzmittel fuer Silizium waessrigen alkalischen Aetzsystemen jeder Konzentration prinzipiell ueberlegen sind. Den zweiten thematischen Schwerpunkt der Arbeit bildet die Modifizierung der nasschemischen Schritte zwischen dem Wafering und dem ersten Hochtemperatur-Fertigungsschritt in der Solarzellen-Produktion, der Emitterdiffusion. Kernanliegen des praktischen Teils dieses Arbeitspaketes ist zum einen die Suche nach alternativen Texturmitteln zum 2-Propanol. Zum anderen sollte der auf die Textur folgende Reinigungsprozess rationalisiert werden, um Prozesskosten zu minimieren, entweder durch eine Straffung des Prozesses durch Verringerung des Chemikalienverbrauchs und einer Reduzierung der Prozesszeit oder durch eine Verringerung der Chemikalienkosten. Mit 1-Pentanol und p-Toluolsulfonsaeure wurden zwei Substanzen ermittelt, welche in der Zukunft als praktikable Alternativen zu 2-Propanol als Texturadditive dienen koennten. Abschliessend konnte noch gezeigt werden, dass drahtgesaegte Substrate, die bei gleicher Prozesszeit mit den neuen Texturmitteln prozessiert wurden, ueber erheblich hoehere mechanische Stabilitaeten verfuegen, als jene, bei denen das klassische Texturmittel 2-Propanol eingesetzt wurde.

    On account of local requirements and because of its economic and technical advantages, cyclic activated sludge process was given preference over conventional technology when building the sewage treatment plant at Neubrandenburg. The process-technical installations were completely accommodated in two circular ponds of the diameter 62.3 m and water depth 5.5 m each, with two reactors to one circular pond each. Construction of the biological treatment plant started in 1998. At its start of operation in November 1998, it was the first European plant employing this technology. With the plant currently running to some 80 to 90 % of its capacity, specified elimination efficiency has been met since spring 1999. (orig.)

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

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

    Full Text Available During the night between 21 and 22 March 2012, a group of young military officers overthrew Mali’s president, Amadou Toumani Touré. The group justified the coup by citing the inability of the regime to both deal with the crisis in the North and provide the army with the appropriate material and manpower to defend the national territory. The coup plunged Mali into violence, and caused a de facto partition of the country. The socio-political turmoil pitting different political and armed factions against each other has continued unabated and has been accompanied by intense mass media debates. In this report we focus on the Malian public debate. By looking at the political class, the international community, and the partition of the country, we analyse representations and stereotypes prevailing in this debate.In der Nacht vom 21. zum 22. März 2012 wurde der Präsident Malis, Amadou Toumani Touré, durch eine Gruppe junger Offiziere gestürzt. Die Gruppe rechtfertigte den Putsch, indem sie auf die Unfähigkeit des Regimes verwies, die Krise im Norden zu bewältigen und die Armee personell und materiell angemessen auszustatten, um die Grenzen das Landes verteidigen zu können. Der Staatsstreich stürzte Mali in eine gewaltsame Auseinandersetzung und führte zu einer faktischen Teilung des Landes. Die sozio-politischen Turbulenzen, in denen verschiedene politische und bewaffnete Gruppierungen gegeneinander antraten, haben seither unvermindert angehalten und wurden von intensiven Debatten in den Massenmedien begleitet. Der vorliegende Bericht konzentriert sich auf die öffentliche Debatte in Mali. Vor dem Hintergrund der politischen Entwicklung des Landes, der Positionen der internationalen Gemeinschaft und der Ursachen für die Teilung des Landes stellen die Autoren die Darstellungsweisen und Stereotypen dar, die in dieser Debatte Verwendung finden.

    In the field of turbo-compressors, the following problems must be solved in order to extend the range of operation: (a) Prevention of rotating stall at part load; (b) Extension of the permissible operating range at part load; (c) Extension of the operation range of radial and side channel compressors in higher vacuum below p{sub s}=50kPa. (c) can be achieved by changing the flow pattern in the rotor and in the region of interaction between the blade wheel and guide wheel of radial compressors or by actively influencing transient flow, e.g. by coupling radial compressor stages with a side channel compressor stage as final stage. The contribution goes into detail about the latter solution. [German] Fuer den Turboverdichterbau sind gegenwaertig folgende Probleme zur Erweiterung der Betriebsbereiche dringend zu loesen: (a) Vermeiden oder beseitigen von Rotating Stall im Teillastbereich,(b) Erweiterung des zulaessigen Arbeitsbereiches im Teillastgebiet, (c) Erschliessung des Arbeitsbereichs von Radial- und Seitenkanalverdichtern im hoeheren Vakuumbereich unterhalb von p{sub s}=50 kPa. Die Erweiterung des zulaessigen Arbeitsbereichs im Teillastgebiet kann durch Veraenderung der Stroemungsstruktur im Laufrad und im Interaktionsbereich zwischen Lauf- und Leitrad von Radialverdichtern oder durch die aktive Beeinflussung der instationaeren Stroemung z.B. durch Kopplung von Radialverdichterstufen mit einer Seitenkanalverdichterstufe als Endstufe erfolgen. Seitenkanalverdichter verfuegen ueber stabile Kennlinien im gesamten Betriebsbereich. Im Kombinationsbetrieb einer Radialverdichterstufe mit nach- oder vorgeschalteter Seitenkanalverdichterstufe praegte die Seitenkanalverdichterstufe dem Kombinationsverdichter ihr stabiles Kennlinienverhalten auf, so dass sich eine stabile Gesamtkennlinie ergibt. Eine Pumpgrenze tritt nicht mehr auf, so dass der Betrieb von Verdichterkombinationen aus Radial- und Seitenkanalstufe im gesamten Kennlinienbereich moeglich ist. Die

    This special report focuses on measurements of elements whose scope goes far beyond the routine monitoring for metals. The present studies are intended to extend the existing knowledge on the pollution situation of the Elbe and certain of its tributaries as well as provide a basis for formulating future guidelines for action. The first step towards this goal is sampling by means of an helicopter. The sampling is followed by a very involved and costly analysis programme, accompanied by extensive quality assurance measures. This is the only way of reliably analysing a large number of elements occurring in extremely low concentrations. Once the data have been recorded the question arises how they are to be evaluated. What schemes are suitable for categorising a large number of elements measured in either the suspended matter or the water compartment? What elements are to be regarded as the result of anthropogenic influences and what are their respective background concentrations in the fluvial system under study? These questions are approached by means of statistical methods which permit identifying elemental patterns and pollution sources as well as optimising the selection of measuring points for future studies. [German] In diesem Sonderbericht steht die Bestimmung von Elementen, die in ihrem Umfang ueber die routinemaessig erfassten Metalle deutlich hinausgeht, im Vordergrund. Die vorliegenden Untersuchungen sollen das bereits vorhandene Wissen zur Beschreibung der Immissionssituation der Elbe und von bestimmten Nebenfluessen erweitern, verbunden mit der Moeglichkeit, zukuenftige Handlungsmaximen zu erarbeiten. Zur Erreichung dieses Ziels steht zu Beginn die Probenahme mit einem Helicopter. Im Anschluss an die Probenahme folgt eine sehr aufwendige und teure Analytik, die begleitet wird von umfassenden Massnahmen zur Qualitaetssicherung. Nur so ist es moeglich, eine grosse Vielzahl von Elementen in extrem niedrigen Konzentrationen sicher analysieren zu koennen. Sind

    The actual developments in policy, economy and society - especially the financial and economic crisis - attend the discussion on a sustainable energy supply. The financing of wind power projects and the reliability of the tariff regime are the decisive preconditions for the realisation of wind power projects. The Federal Government aspires to an amount of 35 per cent of the renewable energy sources at the power supply up to the year 2020. In addition to the utilization of sites by repowering, new priority areas are recognized by the authorities for the energy policy turnaround with wind power. Especially forest areas are focused. Thus, forest areas are attractive for project planners, investors and banks. If the technology supplies a stable and predictable output in the long-term, and if the Federal Government pretends a precise and reliable legal and regulatory environment, an economic utilization of wind power is possible in form of a project financing.

    Soil fungi, including mycorrhiza, are strongly affected by zoil chemical parameters such as the ratio of calcium and/or magnesium to aluminium and the pH-value. So, it was very interesting to compare the rhizospheric microfungal flora between a declining spruce stand and a healthy spruce stand. The site chosen for this investigation was situated in the Vosges in the northeast of France. The rhizospheric soil, from the Ah-horizon of a sandy loam podzol, limed (the healthy spruce stand) or unlimed (the declining spruce stand) was sampled in a 65-year-old Norway spruce forest. The study was made 7 years after liming. Fungal isolations were performed using the dilution plate method. Pronounced differences in species abundance and composition were found between the limed and the unlimed stands. Of the 49 isolated species (24 from declining spruce plot and 34 from healthy spruce plot) only nine were found at both plots. The greatest diversity is observed at the healthy spruce stand; it may be due to the liming. This study indicates that soil microfungi could be sensitive to increased acidity of the rain with subsequent effects. (orig.) [Deutsch] Bodenpilze einschliesslich der Mykorrhizapilze sind stark von bodenchemischen Parameters wie dem Verhaeltnis von Calcium und/oder Magnesium zu Aluminium sowie vom pH-Wert des Bodens abhaengig.

In einem 65jaehrigen Fichtenbestand wurde der durchwurzelte Boden des Ah-Horizontes eines sandig-lehmigen Podsols einer gekalkten (gesunder Fichtenbestand) sowie einer ungekalkten Parzelle (geschaedigter Fichtenbestand) beprobt. Die Studie wurde 7 Jahre nach der Kalkung durchgefuehrt. Die Isolation der Pilze wurde anhand der Verduennungstechnik auf Kulturmedium mit DRBC-Agar durchgefuehrt.

    The United Nations 'Conference on Environment and Development' (Rio de Janeiro, June 1992) adopted the 'Agenda 21' action programme. Agenda 21, Chapter 19 'Environmentally Sound Management of Toxic Chemicals including the Prevention of Illegal International Traffic with Toxic and Dangerous Products' includes detailed instructions for activities for the improvement of chemical safety. As described in Programme Area C 'Information Exchange on Toxic Chemicals and Chemical Risks', international institutions responsible for the exchange of information on chemical risks are to be strengthened. The close cooperation between the Federal Environmental Agency and UNEP Chemicals (until 1995 UNEP/IRPTC (United Nations Environment Programme / International Register of Potentially Toxic Chemicals)) on the exchange of scientific and legal information on hazardous chemicals represents a direct and successful contribution to the implementation of Agenda 21, Chapter 19. UNEP Chemicals was supported in the area of data collection. In return, the noted data of UNEP Chemicals, which were elaborated in international cooperation, were made directly available to the Federal Environmental Agency. This cooperation with UNEP Chemicals represents an important contribution to the international exchange of data on hazardous chemicals. (orig.)

    Full Text Available RANK („Receptor Activator of NF-κB“ und sein Ligand RANKL sind Schlüsselmoleküle im Knochenmetabolismus und spielen eine essenzielle Rolle in der Entstehung von pathologischen Knochenveränderungen. Die Deregulation des RANK/RANKL-Systems ist zum Beispiel ein Hauptgrund für das Auftreten von postmenopausaler Osteoporose bei Frauen. Eine weitere wesentliche Funktion von RANK und RANKL liegt in der Entwicklung von milchsekretierenden Drüsen während der Schwangerschaft. Dabei regulieren Sexualhormone, wie zum Beispiel Progesteron, die Expression von RANKL und induzieren dadurch die Proliferation von epithelialen Zellen der Brust. Seit Längerem war schon bekannt, dass RANK und RANKL in der Metastasenbildung von Brustkrebszellen im Knochengewebe beteiligt sind. Wir konnten nun das RANK/RANKLSystem auch als essenziellen Mechanismus in der Entstehung von hormonellem Brustkrebs identifizieren. In diesem Beitrag werden wir daher den neuesten Erkenntnissen besondere Aufmerksamkeit schenken und diese kritisch in Bezug auf Brustkrebsentwicklung betrachten.

    Heinz Maier-Leibnitz a well-known scientist, nuclear physicist, for 50 years, who publicily supported the idea not to overrate the dangers of peaceful utilization of nuclear energy, has grown tired of talking only to colleagues. He invites a junior fellow physicist, who held engaged speeches against the nuclear power plant Zwentendorf, to an exchange of thoughts. Peter Kafka, an astro-physicist studied the self organisation of the universe from the big bang to the economic crisis and encountered the question of which conditions have to be fulfilled to prevent progress from becoming caranogenous. He became one of the spokesmen of 'political ecology' and called for resistance again large-scale technological use of scientific knowledge. He was enthusiastic about the idea of an exchange of letters, because he - just like his partner - believes in gaining knowledge by discussion. The variety of subjects is sketched briefly in form of three lectures. In the letters both scientists discuss intensly about: - Freedom of science and responsibility of science. - Decisions on energy questions under time-pressure. - Risks of nuclear plants. - Large scale technology and large-scale research or decentralization. - Energy utilization and energy waste. - Nuclear energy and alternatives. - Sense and nonsense of detailed future planning. In the end no one has convinced the other. The reader however finds a lot of new incentives in the letters - printed in unabridged form - a lot of new and significant arguments for a discussion which has only just started.

    Shrinking time-to-market windows are leading to increasingly tight timeframes available for the planning and realization of factories. At the same time, industrial enterprises as clients for factory planning services may at increasingly later stages specify their requirements on the construction of their new factories or the renovation/conversion of existing ones. This state of affairs generates a series of problems such as growing numbers of alterations and thus interruptions in the factory planning process. In order to avoid this happening, the project described in the following included the drawing up of instruments for planning-service providers and the identification of success factors for optimized work scheduling. (orig/GL) [German] Als Folge von tiefgreifenden Veraenderungsprozessen der volkswirtschaftlichen Strukturen nimmt die Beschaeftigung im Bereich der Produktion und der Verarbeitung kontinuierlich ab waehrend gleichzeitig eine stetige Ausweitung des Dienstleistungssektors zu verzeichnen ist.

Prozess der Tertiarisierung vielfach diskutiert, im betrieblichen Kontext jedoch bislang noch sehr unzureichend durch empirisch-fundierte Modelle, Konzepte, Vorgehensweisen, Methoden, Erfahrungen, Best Practice und Erfolgsfaktoren hinterlegt und exemplarisch dargestellt.

  14. Abandoning the idea of 'monopolized supply area'. Abkehr vom Gebietsschutz

    1989-08-14

    The author demonstrates the necessity of demarcated supply areas by pointing to the requirements of safe supply, profitability and fair prices for all power consumers. The absence of supply area demarcation contracts and licence agreements would result in more competition for big power consumers only. The ensuing cost undercoverage would have to be compensated by all the other consumers, thus violating the principle of fair prices. Power supply by other vendors to monopolized areas is neither competition nor deregulation; on the contrary, it means that only few customers will enjoy economic benefits to the detriment of medium-sized industries, trades, crafts and private households. Hence, demarcated supply areas are indispensable. (orig.).

    levels in children decreased markedly in the time from 1992/93 to 1998/99. Cadmium is largely deposited in the kidneys and liver. Urine cadmium levels reflect the cumulative life-long exposure to cadmium. Cadmium deposition in household dust was likewise found to be governed largely by the proximity of the home to the relevant emitters as well as by the cadmium input rate into the home. The degree of cadmium deposition was reflected by the children's body cadmium levels. Older children showed higher cadmium levels than younger ones. Urine cadmium levels in children decreased markedly in the time from 1992/93 to 1998/99. In women the only significant determinant of body cadmium levels was whether or not they lived in the heavily cadmium polluted Hettstedt region. There were only a few cases in which examined children from the Hettstedt region showed a transgression of the values recommended by ''Human Biomonitoring'' Commission of the German Federal Environmental Office. [German] Die vorliegende Arbeit basiert auf Daten einer umweltmedizinischen Untersuchung, die zum Ziel hatte, moegliche gesundheitliche Beeintraechtigungen der Bevoelkerung in dem Huettenstandort Hettstedt im Vergleich zu der Industrieregion Bitterfeld und dem Kontrollgebiet Zerbst zu ermitteln. Diese Studie wurde als Laengsschnittsstudie ueber sechs Jahre konzipiert, aufbauend auf drei regionalen Querschnittsuntersuchungen, die in den Schuljahren 1992/93, 1995/96 und 1998/99 durchgefuehrt wurden.

    If an electric utility holds a monopoly position in a local government district due to a valid demarcation agreement, its attempt to ty payment of the maximum permissible franchise fee to the local government to premature conclusion of a follow-up agreement for a term of 20 years is an infringement of section 26, sub-sec. 2 GWB (law against restraints on competition). The electric utility in this case is liable according to sections 26, sub-sec.2, 35, sub-sec. 1 GWB to pay compensation to the local government amounting to the difference between the maximum permissible franchise fees and the fees actually paid by the utility.

Fuer die Mitgliedstaaten ergibt sich hieraus die Verpflichtung, die erforderlichen Daten zu erheben, auszuwerten und der Europaeischen Kommission zu berichten. In der Entscheidung der Kommission vom 17. Juli 2000 ueber den Aufbau eines Europaeischen Schadstoffemissionsregisters (EPER- 'European Pollutant Emission Register') 2000/479/EG ('EPER-Entscheidung') werden die Anforderungen an Inhalt und Form dieses Verzeichnisses konkretisiert: - Die Mitgliedstaaten berichten der Kommission ueber die Emissionen in die Luft und in das Wasser aus einzelnen Betriebseinrichtungen. Zu berichten sind die Emissionen bestimmter Schadstoffe, die ueber vorgegebenen Schwellenwerten liegen. Das Berichtsformat fuer die Mitgliedstaaten ist im Anhang A2 der EPER-Entscheidung festgelegt. - Der erste Bericht ist im Juni 2003 vorzulegen und soll Angaben ueber Emissionen im Jahr 2001 (bzw. wahlweise 2000 oder 2002) enthalten. Jeder Mitgliedstaat muss zudem einen zusammenfassenden nationalen Uebersichtsbericht erstellen. - Die Europaeische Kommission wird die Emissionsdaten ueber das Internet der Oeffentlichkeit zugaenglich machen. Fuer die Erhebung der fuer das EPER erforderlichen Daten in Deutschland wird ein schrittweises Vorgehen empfohlen: - Am Anfang steht die Identifizierung von Betriebseinrichtungen mit Taetigkeiten nach Anhang I der IVU-Richtlinie. - Angabe des NACE-Kodes der Betriebseinrichtung und Zuordnung der Anhang I-Taetigkeiten (Quellenkategorie) und des NOSE-P-Kodes gemaess Anhang A3 der EPER-Entscheidung. - Festlegung

    Re-orientation is a must if we want to get on. And one of the central notions of such re-orientation, a sort of general denominator summing up the changes of our thinking, so often only brought about in small steps, and eventually of our habits, is the notion of modesty. It is here used to describe an attitude of mind rooted in the discernment of necessities by insight. Such modesty is not at all comparable with sourish renunciation or exhibitionist virtue. Modesty out of insight is the willingness to submit to necessities, is turning away from boasting mania, showiness and extravagance, from routine in thinking and habits. Modesty means to accept a wise and powerful conduct of life.

    This contribution is about the document published as 'Announcement of the Basic Principles of Safety Management Systems in Nuclear Power Plants' in the Federal Gazette (Bundesanzeiger) by the German Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) on July 27, 2004. A kind of checklist contains requirements to be taken into account as 'boundary conditions' in the implementation of safety management systems. In fact, every sentence in the document begins with a 'must' provision. Remarkably enough, these 'Basic Principles' were promulgated by the Ministry without any consultation with advisory bodies, such as the Advisory Committee on Reactor Safeguards (RSK), or organizations of plant operators. The paper contains much that is worth considering, but also many truisms. This article was written because of the way in which the document had been prepared and publicized. An effort is made in this article to generate some understanding of the consequences, in terms of labor psychology and organizational psychology, of the different approaches pursued by regulatory authorities. A key point in this respect is the fundamental difference it makes whether regulations (reglementations) by supervisory authorities address the design of technical components or human behavior. In the former case, precise criteria without any constraints can serve the purpose. Behavioral rules, on the other hand, need a certain measure of flexibility, also in the way mistakes are handled, in order to avoid negative reactions on the part of those concerned. (orig.)

    To classify a liver tumor, image-guided percutaneous biopsy of a liver lesion is indicated. Using ultrasound (US) to guide a biopsy needle into a liver lesion has been proven useful and safe. If a lesion cannot be seen on US or the access to a lesion has been complicated by its position, CT-guided biopsy can be performed. If a lesion cannot be delineated on US or CT, MR-guided biopsy is recommended. Using hepatospecific contrast agents, the time span to delineate tumor tissue can be prolonged. To differentiate diffuse liver disease, transvenous biopsy under fluoroscopic control can be performed if a percutaneous biopsy is contraindicated. In recent years fine-needle aspiration biopsy has been increasingly replaced by coaxial 14-20 G core biopsy, which is a safe and efficient technique to classify liver lesions and has a low complication rate. (orig.) [German] Zur definitiven Klaerung der Dignitaet und Tumorklasse einer Leberlaesion ist eine bildgesteuerte perkutane Biopsie indiziert. Unter Verwendung der Sonographie ist das Verfahren treffsicher und einfach. Die computertomographiegezielte Biopsie ist wegen der ueberlagerungsfreien, reproduzierbaren Darstellung von Leberherden und ihren Nachbarstrukturen in vielen Faellen besser geeignet. Fuer Laesionen, die sich weder mit Ultraschall noch mit CT biopsieren lassen, bietet sich die Magnetresonanztomographie an. Durch den Einsatz leberspezifischer Kontrastmittel kann das Zeitfenster zur Durchfuehrung einer Biopsie verlaengert werden. Zur Abklaerung diffuser Lebererkrankungen wird bei kontraindizierter perkutaner Biopsie eine transvenoese Leberbiopsie unter Durchleuchtung empfohlen. Die in den 1980er Jahren propagierte Feinnadelaspirationsbiopsie wurde zunehmend durch Stanzbiopsien (Durchmesser 14-20 gg) in koaxialer Technik ersetzt, da diese eine zuverlaessige artdiagnostische Klassifikation bei niedriger Komplikationsrate ermoeglichen.

    Worldwide the German efforts to achieve a high safety level in radiation protection are considered as being exemplary. DIN standards for radiation protection are regarded as technical 'implementing statutes' of the Radiation Protection Ordinance, i.e. they are used as a concentrated collection of pertinent expert knowledge. With the new DIN pocketbook 159 'Radiation Protection' this now will be substantially facilitated and becomes possible for all experts from nuclear engineering, medicine, research and teaching as well as administration at an economic price. Out of the about 120 DIN standards valid at the time 55 are completely reprinted here for the beginning. They deal with fundamentals (terminology, classification etc.), radiation measurement and dosimetry, laboratories and laboratory equipment, shielding, radiation sources for medical and engineering application, radiation monitoring of the atmosphere and of surfaces.

    Despite successful reduction of the general lead exposure, this heavy metal is still a matter of public concern due to the fact that associations with intellectual impairment or delayed puberty are found to correlate with very low lead blood concentrations. Lead in tap water is still an important contribution to lead exposure which may cause health risk for infants.

    The specific characteristics of a pipe conveyor, which are due to its operating principle, allow transportation solutions which are not possible with other conveyor systems; or if they are possible, then only with considerable restrictions or additional expenses. The enclosed design of the pipe conveyor protects the material from the environment and the environment from the conveyed material. The system, thus, makes a valuable contribution towards achieving environmental protection objectives and in meeting official regulations. The pipe conveyor handles both tight curve radiuses and steep inclines. This permits a very flexible route and also allows existing obstacles to be bypassed. Consequently, solutions can often be found which do not require any changes to be made to the existing terrain or plant structures. The investment costs of just the conveyor can sometimes be slightly higher for a pipe conveyor than for a conventional troughed belt conveyor. But if the pipe conveyor can take full advantage of its special features, then these additional costs become quite relative very quickly. And if, for example, transfer points, alterations of existing facilities, earthwork, or expensive dust and noise protection measures can be avoided due to the very flexible route layout of the pipe conveyor, then these savings on part of the customer are much higher than the additional costs for this perfect conveyor system. All told, it is possible to solve challenging conveying tasks with great efficiency while also saving resources when the pipe conveyor is used; thus, producing a sustained benefit to both the operator and the environment.

    Anaerobic stabilisation is an established technology for reducing sewage sludge volumes, but it has the drawback of low conversion rates. The speed of the process is determined by the hydrolysis of the solid fraction of the sludge. According to the current state of knowledge, exoenzymes produced by the fermenting microorganisms attack the particulate material and dissolve monomers. Production of exoenzymes is an energy-consuming process for the microorganisms; it reduces the energy gain and slows down cell growth. The same bacteria are responsible for aerobic and anaerobic hydrolysis. Therefore, the process of sludge destabilisation can be intensified considerably by making the whole organic fraction biologically available, i.e. by replacing the slow stage of enzymatic sludge hydrolysis by a chemical, thermal or mechanical stage. Sludge disintegration by one of these processes would intensify anaerobic degradation, reduce sludge volumes and enhance biogas production. (orig.) [German] Die anaerobe Stabilisierung ist anerkannte Regel der Technik und fuehrt zu einem teilweisen Abbau der organischen Bestandteile des Rohschlammes. Eine Verminderung der zu entsorgenden Schlammmasse geht damit einher. Wesentlicher Nachteil der anaeroben Klaerschlammstabilisierung ist die geringe Umsatzleistung dieses Prozesses. Dem Aufschluss der Feststoffe/grossen Molekuele des Schlammes kommt eine Schluesselrolle zu: die Hydrolyse der Rohschlammfeststoffe stellt den geschwindigkeitsbestimmenden Teilschritt des aneroben Abbauprozesses dar. Nach den gegenwaertigen Vorstellungen greifen von den fermentierenden Mikroorganismen produzierte Exoenzyme das partikulaere Material an und loesen Monomere heraus. Die Herstellung der Exoenzyme ist fuer die Mikroorganismen energetisch sehr aufwendig und vermindert den Energiegewinn und damit das Zellwachstum. Die Hydrolyse ist unabhaengig davon, ob sie aerob oder anaerob erfolgt, sie wird von denselben Bakterien bewerkstelligt. Man kann sich demnach vorstellen, den Prozess der Schlammstabilisierung erheblich zu intensivieren, wenn man dafuer sorgt, dass die gesamte organische Fraktion biologisch verfuegbar gemacht wird. Man ersetzt quasi den langsamen Schritt der enzymatischen Schlammhydrolyse durch eine chemische, thermische oder mechanische Vorbehandlung. Man spricht auch von Desintegration des Schlammes und versucht so, die traditionelle 'technische Faulgrenze' zu ueberwinden. Gelingt dies, werden der anaerobe Abbau intensiviert, die zu entsorgenden Schlammengen reduziert und mehr Biogas erzeugt. (orig.)

    This short article discusses the experience gained by the local electricity utility in Flims, Switzerland, on reading out its customers' electricity meters via the Internet. The utility uses the cable-TV network - which it also operates - to automatically transmit counter values to the utility's central server. Remote locations send data via the GPRS mobile network. The system provides consumers with monthly bills and allows the utility to plan mains-loading in a better way. The advantages of the system are discussed, in particular with respect to the liberalisation of the electricity market. The extension of the system to provide remote metering of gas and water is also discussed.

    The author deals with the precepts and credibility of environmentalists, the pseudo-scientific dameanour of certain authorised experts, and the sometimes ruinous activities of `environmental organisations`. In analogy to the spirit of humanism as an attitude of respect towards one`s fellow human beings he sees environment protection as a friendly attitude towards nature. He points to the case of a premature, careless concellation of a hydropower project as an example of the far-reaching consequences of what he considers false environmentalism. (orig.) [Deutsch] Der Verfasser setzt sich mit dem Anspruch und der Glaubwuerdigkeit der Umweltschuetzer, der anzutreffenden Pseudowissenschaftlichkeit von Sachverstaendigen und dem teilweise verhaengnisvoll wirkenden Aktivitaeten von `Umweltorganisationen` auseinander. Er postuliert in Anlehnung an den Humanismus, als positive Einstellung gegenueber den Mitmenschen, den Umweltschutz als positive Haltung gegenueber der Natur. Beispielhaft weist er auf die Tragweite einer leichtfertigen Vorverurteilung im Falle eines Wasserkraft-Projektes hin. (orig.)

    Against the background of the discussion concerning the Reimbursement Act (StrEG) and the draft Renewable Energy Sources Act (EEG), the Bundesverband Windenergie e.V. (BWE) asked the Deutsches Windenergie-Institut (DEWI) to investigate the current cost situation of wind power in Germany. This involved a statistics of wind power generation cost over a period of 20 years. The data were obtained from wind power system operators, technical experts, producers of wind power systems and insurance companies. It was found that especially the cost of component replacement was higher than expected, so that long component life must be one of the main goals in the further development of wind power systems. According to the technical experts, component life today is much less than the rated life of 20 years. [German] Vor dem Hintergrund der Diskussion um das Stromeinspeisegesetz (StrEG) bzw. des Neuentwurfs zum Erneuerbare-Energien-Gesetz (EEG) wurde das Deutsche Windenergie-Institut (DEWI) vom Bundesverband Windenergie e.V. (BWE) beauftragt, eine Studie ueber die aktuelle Kostensituation in Deutschland zu erarbeiten. Erstmals wurden hierbei Stromerzeugungskosten aus Windenergieanlagen (WEA) ueber einen Zeitraum von 20 Jahren ermittelt. Hierbei wurden Umfrageergebnisse von Betreibern von WEA, technischen Sachverstaendigen sowie von Herstellern von WEA und Versicherungsgesellschaften verwendet, um belastbare Aussagen ueber Betriebskosten und notwendige Ersatzinvestitionen zu erhalten. Insbesondere die Aussagen ueber notwendige Ersatzinvestitionen durch die technischen Sachverstaendigen waren hoeher als erwartet, so dass es in Zukunft Ziel sein muss, insbesondere bei der Weiterentwicklung von WEA auf wesentlich laengere Lebensdauern der Bauteilkomponenten von WEA zu draengen. Nach Aussage der technischen Sachverstaendigen liegen bisher die Lebensdauern wesentlicher Bauteile der WEA, wie Rotor, Bremssystem, Pitchregelung usw., weit unter der kalkulierten Lebensdauer von 20 Jahren

    Full Text Available The Geschichtsbüro Reder, Roeseling & Prüfer, Cologne sees itself as a service provider for applied history. Between the poles of historical scholarship’s standards for knowledge and the communicational procedures of marketing agencies, the Geschichtsbüro’s main goal is to make history serviceable. Understanding applied history as an independent form of knowledge and communication, the Geschichtsbüro mainly compiles historical accounts of corporate history for business organizations and provides advice for the creation and maintenance of archives. The historical accounts are presented in different media formats such as books, leaflets, magazines, movies, audio files, and online content. Each media product differs in perspective, purpose, objective, language, and design. The products distinguish the client’s historical self-reflection through history. This dual nature elevates applied history to an independent form of historical culture in practice. Engaging in in-house history aides in the formation of corporate identity in the present, and influences future developments. The Geschichtsbüro’s success emphasizes that an increasing number of business organizations are showing an interest in historical reflection, and confirms the relevance of applied history in today’s as well as tomorrow’s business culture.

    This final report for the Swiss Federal Office of Energy presents the results of a preliminary study on the technical, logistical and economic possibilities of agricultural biogas production for use as motor fuel. The study was made for a geographically limited region in the Swiss Canton of Lucerne. The reason for the choice of this area - which exhibits a high density of cattle and fowl - and its high potential for the production of biogas from animal excrements are discussed. The economic viability of three possible variants of biogas usage are discussed - its use as a fuel for electricity generation, the processing of the biogas and its injection into the natural gas mains and storage of the biogas in compressed-gas cylinders. Also, the relevance of biogas production in terms of environmental protection is emphasised - ammonia emissions from liquid manure poses a serious problem for the region. Further, political and market development aspects are discussed.

    Directory of Open Access Journals (Sweden)

    Susanna Ulinski

    2013-09-01

    Full Text Available This essay explores the alleged trade-off between reducing overconsumption and promoting ethical consumption, especially in the form of Fair Trade. While Fair Trade is primarily concerned with promoting greater equity in international trade, it does not address problems of ecological exhaustion through overconsumption. Furthermore, Fair Trade could promote increased consumption by inducing false consciousness among consumers. In this context, I propose an integrative approach of trying to address these two problems simultaneously by changing the social patterns of consumption, instead of interpreting them as diametrically opposed. Awareness is the first step in inducing a behavioural change. On an individual level, Fair Trade is fairly successful at creating sensational feedback processes, which increase the awareness for the social and environmental implications of individual consumer behaviour. Moreover, on an aggregate level, Fair Trade changes social patterns of consumption to promote ethical consideration in the context of consumer decision-making. Although Fair Trade is not primarily concerned with the level of consumption, it can help bring forth a change in consumption patterns in order to reduce overconsumption.

[German] Strom aus Kohle und Atom praegt seit Jahrzehnten Deutschlands Energiepolitik. Aber die Schadensbilanz dieser Politik hat den Aufschwung der erneuerbaren Energien moeglich gemacht.

  7. Die Bestimmung der Ephemeridenzeitkorrektur aus Aufnahmen der totalen Sonnenfinsternis vom 30. Juni 1973.

    Science.gov (United States)

    Haupt, H. F.; Firneis, M. G.; Fritzer, J. M.

    Photographs of the partial phases of the 1973 June 30 total solar eclipse taken in Mauretania were used to derive the correction ΔT = ET-UT. The introduction describes the problems and history of ΔT determinations. After a brief description of the expedition, location, instruments, and the observations, the reduction is treated in some detail. Probably due to the improper exposure of the films the radius of the Sun turned out too small, while the lunar radius showed a peculiar increase after totality. Correspondingly, this increase resulted in a decrease of the Sun-Moon distances that had to be accounted for by the introduction of a correction function. After having applied this plausible correction several assumptions of ΔT were made in the computations and the one yielding the mean value of the residuals equal to zero, was taken as the ΔT of the date, namely ΔT1973.5 = +54s-91, which is in good agreement with other determinations.

    CERN Document Server

    Freytag, Carl

    2016-01-01

    Dieses Buch erklärt die physikalischen Grundlagen und die Technologien der Elementarteilchenforschung und beschreibt allgemeinverständlich Teilchenbeschleuniger und -detektoren sowie ihr Zusammenspiel. An einigen Meilensteinen der Forschung – von der Erzeugung von Transuranen über die Entdeckung exotischer Mesonen bis zum Higgs-Boson – zeigen die Autoren den Weg von der Theorie über das Experiment zum Forschungsergebnis auf. Gravitonen, Higgs-Teilchen, Neutrinos und Quarks – das Interesse an den kleinsten uns bekannten Teilchen ist seit Jahrzehnten ungebrochen und rückt damit auch die Laboratorien in den Blick, die an die Grenzen der Physik vorstoßen: Neben dem größten Experimentierfeld, das wir haben – dem Universum selbst - sind es die gigantischen Maschinen der Elementarteilchenphysik in Großforschungseinrichtungen wie dem CERN und dem DESY. Mit ihnen versuchen Forscher weltweit unter Einsatz extrem hoher Energien Zustände zu simulieren, wie sie zum Beginn unseres Universums kurz nach d...

    This booklet issued by the Swiss National Cooperative for the Disposal of Radioactive Waste NAGRA takes a look at the use of clay strata for the storage of radioactive wastes in deep-lying repositories. First of all, a geological foray is made concerning the history of the use of clay and its multifarious uses. The characteristics of clay and its composition are examined and its formation in the geological past is explained. In particular Opalinus clay is looked at and the structures to be found are discussed. The clay's various properties and industrial uses are examined and its sealing properties are examined. Also, Bentonite clay is mentioned and work done by Nagra and co-researchers is noted.

    The stance of fiscal policy is commonly assessed by the size of the annual budget deficit and public debt. Both indices fail, however, to correctly reflect the long run financial burden of government programs such as social security. An alternative to "deficit accounting" is "generational accounting" which in particular reveals the intergenerational distribution effect of government legislation. The present paper applies generational accounting on the pay-as-you-go financed part of old age pe...

    Illustrious, eloquent, and yet easy to read for the interested layman, the book begins with alleged deplorable conditions at the reprocessing centre La Hague, portrays, amongst other things, the spying on and supervision of persons in the nuclear field and in research, the misuse of fissile material, and threats and blackmail as a consequence thereof, human error as a cause of accidents, and it concludes with a nonviolent new International against the nuclear State, against technological tyranny. Titles of chapters: the hard road; radiation feed; the gamblers; homo atomicus, the intimidated; the 'proliferators'; nuclear terrorists; those supervised; the smooth road. It remains an open question whether the book contributes to defusing the nuclear controversy - in the book almost an ideology - and to bringing the two sides closer together.

    Soils, the basis for human, plant and animal life, are exposed to quantitative and qualitative deterioration. Quantitative deterioration refers to paving of ground but also to erosion and soil destruction. There are new regulations for physical protection of soil which refer to soil erosion, compacting and handling of soil during building construction. (orig.)

    With 570 concrete poles and 80 km of tubes, 100,000 m{sup 3} of ground serve as a cold and heat storage resservoir for a building. The building houses a printing shop, which needs cooling in summer and heating in winter. The energy pole system can be used as a dual system for heating and cooling in both seasons. The project is a pilot project of the BWE (Swiss General Office for Utilities and Power Supply), who also started an extensive accompanying measurig campaign. The results during the first year of operation were very positive, and the performance of the energy pole system was up to expectations. (orig.) [Deutsch] Mittelpunkt der PAGO-Energietechnik ist das Energiepfahlsystem. Mittels 570 Betonpfaehlen und 80 km Rohrschlangen wird das Erdreich unter dem Gebaeude als ueber 100.000 m{sup 3} grosser Waerme- und Kaeltespeicher genutzt. Ueber dieses Energiepfahlsystem wird dieser Druckereibetrieb mit hohen Anforderungen an das Raumklima und viel Maschinenabwaerme sehr umweltschonend im Winter behizt und im Sommer gekuehlt. Das Besondere an diesem System ist diese ganzjaehrige Doppelnutzung zu Heiz- und Kuehlzwecken. Aus diesem Grunde wurde dieses Projekt vom Bundesamt fuer Energiewirtschaft (BEW) als Pilot- und Demonstrationsprojekt anerkannt. Zur Ueberpruefung von dessen Ausbeute und der Wirksamkeit der gesamten Energietechnik wurde vom BEW ein umfangreiches Messprojekt gestartet. Der Innovationswert der PAGO -Energietechnik liegt allerdings nicht allein im Einsatz der alternativen Komponenten. Mindestens so wichtig ist die Konzeption und die Feinabstimmung der gesamten Energietechnik. Der Betrieb lief im ersten Betriebsjahr sehr positiv und von Anfang an ohne groessere Probleme. Das Energiepfahlsystem konnte im wesentlichen die Erwartungen erfuellen. (orig.)

    The rapid change in the energy sector from a seller's market to a buyer's market shifted the focus to customer relationship management as a priority task of management. Any professional CRM system requires as a basic step a new corporate approach, abandoning departmental thinking for a holistic, process-oriented corporate management concept, which in turn has to rely on efficient marketing and sales information systems offering to staff members online access to the relevant information about customers and their needs. As for industrial or commercial buyers for example, such a database has to show the companies' demand profiles, information on plant and equipment as well as the processes, contracts, and orders. (orig./CB) [German] Der schnelle Wandel der Energieversorgung vom Angebots- zum Kaeufermarkt stellt den Kunden in den Mittelpunkt aller Bemuehungen.

    Due to a significant overlap of the two syndromes, differentiation of degenerative dementia of the Alzheimer-type from vascular dementia may be difficult even when imaging studies are available. White matter changes occur in many patients suffering from Alzheimer's disease. Little is known about the impact of white matter changes on the course and clinical presentation of Alzheimer's disease. High sensitivity of MRI in the detection of white matter alterations may account for over-diagnosing vascular dementia. The clinical significance of white matter alterations in dementia is still a matter of debate. The article reviews current concepts about the role of white matter alterations in dementia. (orig.) [German] Die Zuordnung einer Demenzerkrankung zu einem neurodegenerativen Pathomechanismus, wie der Demenz vom Alzheimer-Typ (DAT) oder einem vaskulaeren Pathomechanismus, kann trotz der Verfuegbarkeit bildgebender Verfahren Probleme bereiten. Ueberlappungen neurodegenerativer und vaskulaerer Mechanismen sind haeufig. Mikroangiopathische Veraenderungen des Marklagers finden sich bei einem hohen Anteil von Patienten mit der klinischen Verlaufsform einer Demenz vom Alzheimer-Typ. Es ist unklar, ob es sich um eine Koinzidenz zweier Pathomechanismen handelt oder ob eine wechselseitige Beeinflussung stattfindet. Die hohe Sensitivitaet der Magnetresonanztomographie bei der Erfassung mikroangiopathischer Veraenderungen des Marklagers koennte dazu fuehren, dass zu vaskulaere Demenzerkrankungen haeufig diagnostiziert werden. Der Einfluss mikroangiopathischer Veraenderungen des Marklagers auf den Demenzverlauf wird kontrovers diskutiert. Die vorgelegte Arbeit gibt eine Uebersicht ueber die aktuellen Konzepte zum Stellenwert von Marklagerveraenderungen bei Demenzerkrankungen. (orig.)

    Based upon the calculation of US authorities 97% of all accidents are caused by mistakes of the driver. Due to this fact one of the major focuses of research activities of the automobile industry was put on the development of new assistance systems for the driver. These technologies indicate potential risks to the driver and support him with decisions in terms of the actual driving behaviour in dangerous situations. This work presents a new system that provides prospective information in real time about the course of the road lying ahead of the vehicle. Based on this data the driver's assistance system will provide a prognosis on the force working on the vehicle and then propose a suitable speed strategy that guarantees a safe drive at any time (orig.) [German] Nach Berechnungen von US Behoerden sind 97% aller Unfaelle auf Fehlverhalten seitens des Fahrers zurueckzufuehren.

Diese Technologien weisen den Fahrer auf potentielle Gefahren hin und unterstuetzen ihn bei der Entscheidung hinsichtlich des aktuellen Fahrverhaltens in gefaehrlichen Situationen. In der vorliegenden Arbeit wird ein neuartiges Verfahren vorgestellt, welches vorausschauend Informationen ueber den vor dem Fahrzeug zu erwartenden Fahrbahnverlauf in Echtzeit bereitstellt. Basierend auf diesen Daten wird vom Fahrerassistenzsystem eine Prognose ueber die auf das Fahrzeug wirkende Kraft erstellt und anschliessend eine geeignete Geschwindigkeitsstrategie vorgeschlagen, die ein sicheres Durchfahren der Kurve zu jedem Zeitpunkt gewaehrleistet.

    The 2nd Workshop on measuring systems for steady-state and transient multiphase flows was held at Rossendorf on September 24/25, 1988. 14 Papers were presented, whose subjects ranged from optical and radiometric methods to impedance sensors, hot film probes and model-assisted methods of measurement. In the field of computer simulation of multiphase flow, a trend towards 3D models was identified which makes higher demands on the spatial and time resolution and on the information volume to be acquired and processed. [German] Vom 24.-25. September 1998 fand in Rossendorf der 2. Workshop ueber Messtechnik fuer stationaere und transiente Mehrphasenstroemungen statt.

Auf dem Gebiet der Computersimulation von Mehrphasenstroemungen zeichnet sich zunehmend der Uebergang zu dreidimensionalen Modellen ab. Hieraus ergeben sich neue Anforderungen an die Messtechnik, sowohl hinsichtlich der raeumlich-zeitlichen Aufloesung als auch was den Umfang der zu erfassenden Informationen betrifft. (orig./AKF)

    In a circular dated 1st Sept. 1994, i.e., after the issue of the pertinent planning decision, the Federal Environmental Ministry, BMU, laid down uniform standards on measurements and the parameterisation of the evaluation system for different operation states and loads. Subsequently, TUeV, the German Technical Control Board, prepared the parameterisation curves on the basis of these specifications. The implementation of the BMU paper of 1st Sept. 1994 did not result in any advantage, nor did it lead to a reduction of plant emissions, nor to advantages in the operation of the waste-fuelled cogeneration plant. On the contrary, elevated gas consumption and operating trouble due to frequent feed stops worsened the operating state of the plant. Elevated crude gas temperature in the boiler reduced the lifetime of the two boilers to a critical degree. An operating temperature of 850 C and a residence time of approx. 1 sec. in Burgkirchen waste-fuelled cogeneration plant have not worsened emission values while rendering the plant operable again. [Deutsch] Durch Rundschreiben d. BMU vom 01.09.1994 - also nach Erlass des Planfeststellungsbeschlusses - wurden einheitliche Vorgaben ueber Messungen und Parametrierung des Auswertesystems fuer die verschiedenen Betriebs- bzw. Lastzustaende erlassen. Unter Beruecksichtigung dieser Vorgaben wurden vom TUeV die Parametrierungskurven erstellt. Die Umsetzung des BMU-Papieres vom 01.09.1994 ergab keinerlei Vorteile, weder gab es eine Verringerung der anlagenbedingten Emissionen noch Vorteile fuer den Betrieb des MHKW`s. Im Gegenteil, erhoehte Gasverbraeuche und Betriebsstoerungen durch oftmalige Beschickungsstops verschlechterten den Betriebszustand. Erhoehte Rohgastemperatur im Kessel reduzierten die Lebensdauer der beiden Kessel kritisch. Der Betrieb mit 850 C und mit einer Verweilzeit von ca. 1 sec. fuehrt im MHKW Burgkirchen zu keiner Verschlechterung der Emissionswerte, macht aber die Anlagen wieder betreibbar. (orig./SR)

    In a difficult economic situation where the problems of many companies to adapt to changed economic conditions threaten to supersede ecological interests the Council of Experts appointed by the Federal Environment Minister submitted its 1994 environmental expertise. This scientific political counseling document would deserve little attention if it was limited to the appeal of considering pollution control as an integrated part of all political activities or if it only contained a catalog of measures for the ecological repair of technico-industrial faults and failures. The structural change of economy and the necessity of ecological modernization, however, are taken into account by representing an ecological-economic model which contributes to a long-term conceptional orientation of environmental policy and which is elaborate enough to be suited for the development of solutions to concrete problems. The main points of the expertise are discussed.

Dieses Dokument wissenschaftlicher Politikberatung wuerde wenig Aufmerksamkeit verdienen, erschoepfte es sich in dem Appell, Umweltschutz als integrierten Bestandteil aller politischen Aktivitaeten zu betrachten, oder wuerde es nur einen Katalog von Einzelmassnahmen zur oekologischen Reparatur technisch-industrieller Schadensfaelle enthalten. Was das Gutachten interessant macht, ist die Tatsache, dass es angesichts des Strukturwandels der Wirtschaft und angesichts der Notwendigkeit einer oekologischen Modernisierung der Gesellschaft ein oekologisch-oekonomisches Leitbild vorstellt, das sowohl konzeptionell die Umweltpolitik langfristig orientieren kann als auch bereits soweit ausgearbeitet ist, dass es fuer die Bewaeltigung

    In this study, input variables for chemical transport models were compared from different meteorological drivers each with other and with the measured friction velocities in one place. Friction velocities are used as a measure of the mechanical turbulence, but are made available neither by numerical weather models nor routinely available observations: so they must either recalculate or estimated. In this study, friction velocities (u{sup *}), which is measured for years by the DWD in Lindenberg near Berlin, averaged over 30 minutes and have been made available to FU Berlin, compared with modeled values. The considered models are firstly the diagnostic interpolation model TRAMPER, on the other the prognostic models of the DWD COSMO-EU and the EZMWF. The boundary layer relevant parameters from the NWM were recalculated from the involved groups, which has been made for the COSMO-EU the one from the FU Berlin, the other from IfT in Leipzig.

    No other environmental subject has been discussed so passconately as the damage connected with air pollution. The dying of forests and trees moves many hearts and minds there are many theories and many analyses and studies to have been conducted. The lost link in the chain of evidence is still missing but everything points to the fact that the air pollution is the cause. Gases, dusts, acids and heavy metals from stacks and exhausts have almost broken the camel's back. What kind of substances are these And how can they cause such large damage Where do the come from and how do they act Is it only the forest or are we affected as well What can be done What does the government do These are many questions which this pocket book answers competently in alphabetical order.

    After expiration of the license in 2003 the Swiss Federal Council and the Freiburg District Government issued a new operating license for another 70 years. This new license first of all allows RADAG to continue operation of the existing power plant, situated at the end of a 3,8 km long channel. At the same time, however, it requires the company to commission a new plant besides the existing barrage by the end of 2012, which will increase the present day output from 528 GWh up to 650 GWh per year. RADAG immediately got down working on the project of what would be one of the largest run-of-river power stations in Germany. The new license provides and increase of the total turbine water flow from originally 1 100 m{sup 3}/s up to 1 400 m{sup 3}/s. The new power plant contains one large Kaplan turbine with an installed total wattage of 28 MW, thus increasing the overall wattage up to 108 MW. The total project costs of the new plant amount to about 68 Mio Euro (price level as per 2007), including 4 Mio Euro for environmental measures. (orig.)

    In case of static ambient air, leakages for volumes of 25 x 1,5 l/min and air supplies >= 120 l/min or 25 x 2,0 l/min and >= 160 l/min do not occur. The increasing flow rate of moving ambient air leads to an increase of leakages. They show their largest extensions in case of lateral flow. In addition, they expand together with increasing physiological load. Therefore, the inherent air supply should not be below 160 l/min. The comparison of the dust protection helmet 'Airstream AH 1' with two respirators revealed the lowest additional physiological load for the dust protection helmet. Applicability tests in situ resulted in the following principal objections: contamination and scratches on the visor leading to visibility restriction of the wearer, bad fit, weight distribution and helmet dimensions, pressure sores and chafes of sealing parts and edges, lamp installation. Air supply and movement were felt as too high in case of low ambient temperatures, and in case of high temperatures and physiological strain it was considered as too low. There were only few objections against fan noise, weight and impediment by cable and battery. Based on the results, a specification including monitoring and maintenance of the helmet was made and additional tests for DIN design 58 645, item 7, were induced. Furthermore, a proposal regarding helmet optimisation was made.

    The aim of the present study was to assess the allergic hazard potential of Pt-containing substances emitted from automotive catalytic converters for the population. This was done by determining exposure-effect relationships in subjects occupationally exposed to platinum compounds in a catalytic converter manufacturing company. The company had been deemed suitable because it could be assumed that the extensive technical industrial safety measures implemented there would make for a considerably reduced exposure to platinum compounds compared to, for example, a platinum separating plant. Exposure-effect relationships were determined on the basis of platinum measurements in a catalytic-converter-manufacturing plant and of a record of new sickness cases.

Der gewaehlte Katalysatorbetrieb war deshalb als geeignet betrachtet worden, weil durch weitgehende technische Arbeitsschutzmassnahmen eine wesentlich geringere Exposition gegenueber Platinverbindungen anzunehmen war als zum Beispiel in Platinscheidereien.

    The effect of the cellular immune response by total body irradiation was investigated. The transplant survival (skin grafts) was determined as immune parameter. Donors were colony bred Wistar rats and recipients were colony bred Sprague Dawley rats. The investigations were carried out with irradiated rats and with rats irradiated after thymectomy and/or adrenalectomy as well as with animals without irradiation. A single total-body irradiation (1 and 2 Gy) was administered. The skin graft survival in irradiated rats was significant shorter (radiogenic immunostimulation) than in unirradiated rats; there were no significant differences between the operated (thymectomy and/or adrenalectomy) and not operated animals. Including precedent examinations this radiogenic immunostimulation is caused by relativly selective inactivation of T-suppressor cells. (orig.).

    In 2000 economic growth in Austria amounted to 3.2 %. The inflation rate rose from 0.6 % in 1999 to 2.3 % in 2000. Apart from the increase in crude oil price the rise in indirect taxes contributed as well to the upward trend of prices. According to Eurostat the unemployed rate went down to 3.7 %. According to the agricultural accounts agricultural incomes were rising again in 2000 for the first time since 1995 (+1.6 %). The final production of agriculture and forestry amounted to ATS 62.9 billion (+0.4 %, of which agriculture ATS 50.3 billion, and forestry ATS 12.6 billion). Whereas the yields in plant production decreased in particular due to the drought (-6.1 %), the gross yield from animal husbandry increased by 8.1 %. this rise is in particular due to the recovery of the pig market. According to the Austrian Institute of Economic Research (Wirtschafts-forschungsinstitut WIFO) direct payments rose compared to the year before by ATS 0.5 billion to ATS 17.8 billion. The share of agriculture and forestry in the GDP decreased to 1.3 %. According to WIFO the number of persons working full-time in the agricultural sector totalled 140,000 in 2000. The agricultural quota amounted to 4.0 %. In agricultural trade a rise was recorded again in exports (15.6 %) as well as in imports (14.7 %) in 2000 compared to the year 1999. Exports of agricultural goods totalled almost ATS 47 billion, of which two thirds were exports to EU member countries. Agricultural imports amounted to almost ATS 61 billion, of which three quarters came from EU member countries. The agricultural trade balance decreased to - ATS 14 billion. In 2000 the food industry was severely hi in particular by the current meat crises. European consumers organizations and associations call for the rethinking in the subsidisation policy and a promotion of organic farming. The core elements of the European foodstuffs model should be in particular security and safety, quality, origin, and diversity. In 2000 Austrian tourism recorded a slight increase in overnight stays of 0.8 % (in 1999: +1.4 %). The number of overnight stays amounted to 113.7 million. As far as overnight stays on farms are concerned there was in particular an increase in the category 'holiday apartments' (+7.4 %) compared to the year before. The number of overnight stays in the category private farm holidays (up to 10 beds, without holiday apartments) decreased by 3.8 %. (author)

    Germany is world champion. In the production of lignite. But not only the brown coal, the coal leaves traces to. A quarter of German greenhouse gas emissions are discharged from the 30 largest coal-fired plants. But with its hunger for coal Germany neither in Europe nor in the world ist not alone. The governments of the 20 largest industrial countries subsidize the search for new fossil fuels each year with many billion dollars, although these projects have no future. In addition, there is the partly dramatic damage to the air, on the environment and on humans. Above all reports the Coal Atlas. It is published at a time, in which in Germany is an intense debate in progress about the future of this energy sector. In fact, it comes to the phasing out of coal for generating elektricity. The coal Atlas shows in understandable texts with illustrative graphics: This is technically possible and necessary. [German] Deutschland ist Weltmeister. Bei der Foerderung von Braunkohle.

    Biomethane, Bio-Natural Gas, Biogas or Power-to-Gas? For several types of bio- and renewable fuels do a variety of terms exist. Therefore, it is not only preserved for experts but also increasingly difficult for the general public to keep track of different types of terms. This fact leads to an additional uncertainty in a topic that is contro-versial from the beginning (Food-fuel discussion, E10-Chaos). At least since the so-called ''renewable substitutes for gasoline'' the clutter of terms is obvious. Above all, the customer is not taken this long and left in uncertainty. But without taking along the customers, it will almost be impossible to place new types of fuels in the market in future. The times where gasoline and diesel were solid ''alone'' at fuel stations are passed long ago and the offer of new fuels is almost growing day by day. The aim therefore already has to be, to take along the customers with terms, which are unmistakable and easily to understand including related public relations for the changing situations for the terms of fuels.

    A diagnostic model for the estimation of orographic precipitation during large-scale upslide motions is presented. It is based on linear theory for 3-D mountain overflow. From the simulated vertical velocities rain intensities at the ground are calculated using a model for precipitation formation. Due to the small number of free parameters and because of the simple initialisation method, e.g. with single radiosonde data, the model is used for regionalisation of precipitation from rain gauge observations as well as for deriving its statistics under dynamical constraints. For Southwest Germany and Eastern France, with the low mountain ranges of the Vosges, Black Forest and Swabian Alb, model simulations are performed for individual events with heavy rainfall. Thereby it is evaluated, how realistic rainfall patterns can be obtained with a combination of model simulations and measurement data. Mean rainfall distributions are derived from simulations of all extreme events with 24-h totals over 60 mm at selected rain gauge stations between 1971 and 2000. Furthermore the calculation of rain sums for different return periods is performed using extreme value statistics. So it is possible to quantify the hazard potential of heavy rainfall, which may cause flooding or landslides, in high spatial resolution (2.5 x 2.5 km). (orig.)

    2012-07-01

    The main objectives for the improvement of utility boilers are to increase their overall efficiency. Therefore, steam parameters need to be increased leading to temperatures which may exceed the limiting temperatures of the tube materials. Considering these aspects, the single tube temperatures of a powerplant have to be determined to prevent material failure. In order to account for the mutual impact of combustion and water-steam-cycle, a coupled simulation is performed to calculate the single tube temperatures. Apart from the interaction of combustion and water-steam-cycle, the design of the heat exchanger headers is relevant. On the basis of a detailed investigation of the pressure distribution in steam distributors and headers, a new quality regarding the prediction and calculation of single tube temperatures will be obtained. By means of a similarity analysis, the governing geometry relations associated with the pressure change in steam distributors and headers are identified. The parametrisation of this approach is done by comparing the measured pressure values of an air-flow divider-collector-combination. The portability of the air-flow results to water, respectively steam is approved. Based on the experimental data, computational fluid dynamic simulations of all governing geometrical relations are performed. The validity of the similarity based approach is shown for nearly all geometrical relations corresponding to real utility boiler application. Deviations between experiment and calculations based on the similarity approach are only evident for very short distances of separating tubes originating from secondary vortices. However, the impact of these vortices to the global mass distribution is minimal. The comparison between measured and calculated single tube temperatures from a lignite-fired utility boiler shows the good match between the simulated and measured temperatures. The single tube temperatures of a heat exchanger across the boiler width are calculated correctly. The predicted temperatures of vertically arranged tubes show certain discrepancies due to the fact that the soot-blowing equipment leads to different deposit thicknesses within the heat exchanger. This effect is currently neglected in the coupled simulation. By enabling the use of high performance computing, a significant reduction of computing time for the coupled simulation is achieved. This is a necessary condition to optimize utility boilers already in operation and those yet to be built.

  12. Clay shale as host rock. A geomechanical contribution about Opalinus clay; Tonstein als Wirtsgestein. Ein geomechanischer Beitrag ueber Opalinuston

    The Opalinuston is a prominent rock representing the type of organic clay shales or clay stones within the sequence of Triassic and Jurassic marine sediments in Southern Germany. The rock forms a homogenous unit some ten meters thick. The degree of consolidation of this type of pelitic rock depends mainly on the former load conditions, but is also dependent on the long-term weathering and even on the present exposition. The geomechanical parameters such as shear strength, tensional strength and permeability vary with the state of consolidation and become important when the use is discussed of such rocks for radioactive waste disposal. A tunneling project at the northern escarpment of the Swabian Alb (Southwest Germany) within the Opalinus clay offered the rare opportunity to obtain fresh unweathered rock samples in greater amounts compared to fresh drilling cores from which geomechanical investigations are usually undertaken. Consequently, the results of geomechanical laboratory testings are presented in order to compare here the results of multistep triaxial compression tests, of hydraulic fracturing laboratory tests and of some other tests for rock characterization with the corresponding results of Opalinus clay sites in Switzerland that were investigated by the Swiss Nagra Company for host rock characterization. After a discussion of the relevant state of fresh Opalinus clay, especially of suction pressure conditions and saturation state, the results of triaxial shear tests are presented. Increasing shear deformation at increasing pressure and unchanged water saturation do not result in a significant strength reduction of the Opalinus clay. The rock shows increasing cohesion and stiffness, if multiple loading has repeatedly reached the failure point. Thus there is no increased permeability with continued shearing. Only at the beginning of the shearing process is a temporarily increased permeability to be expected due to dilatation processes. An increased permeability, however, is generated by hydraulically injected water when fracturing may occur. Such fracturing depends on the injection rate: Low injection rates lead to local structural disintegration, higher injection rates result in single crack propagation as is known from hydraulic fracturing tests. Such hydraulically formed fractures later tend to close with an increase of surrounding stress. This closure increase is comparable to a healing process because new hydraulic fractures can be generated consequently at higher stress levels. Such laboratory test results seem to be favorable when using fresh Opalinus clay as a host rock, but they are difficult to verify at standard in-situ-conditions with weathered or partly deconsolidated rocks. Similar organic-rich and differently overconsolidated pelitic rock types display a wide spectrum of geomechanical behaviors despite the fact that no visible or physical differences can be provided. A direct comparison of the Opalinus clay parameters from the Swabian Alb, as investigated here, and from Switzerland, as determined by the Nagra Company, show differences in the effective shear strength. Nevertheless, the scatter is much smaller than that occurring for undrained shear stress differences as a function of water content. Consequently, for each project one must define exactly the relevant conditions within the different pelitic rocks in order to determine the useful geomechanical parameters. Additionally, it can be an advantage to use great depths because of the favorable geomechanical characteristics of Opalinus clay at high pressure. In this way some of the construction problems in Opalinus clay may be reduced if not avoided by using deep boreholes for waste deposition.

Ivens, Marker, Godard und Jarman thematisieren in und mit ihren Filmen die Unverfügbarkeit der Erinnerung und halten trotz ihres Zweifels an der Abbildbarkeit von Welt und ihrer Einsicht in die Uneinholbarkeit der Vergangenheit den Horizont der Möglichkeit von Erinnerung offen. In Essayfilmen sind es vor allem die selbstreflexive Selbstvergewisserung, die Einsicht in das unausweichliche Verfehlen der Vergangenheit und der melancholische Rückblick auf eine verloren gegangene Ganzheit, die einen fühlenden Verstand und ein denkendes Herz generieren.Christina Scherer’s dissertation points to the structural equivalence between the aesthetics of the essay film and the process of remembering. Ivens, Marker, Godard and Jarman make the unavailability of memory their central theme. Despite the filmmakers’ doubts about the possibility of replicating a true image of the world and their knowledge of the irretrievability of the past they nonetheless insist on the possibility of memory. Reflectively positioning oneself, acknowledging inevitable errors of the past, and looking back in melancholy on a lost entirety are some of the strategies in essay films which generate a sympathetic mind and a thinking heart.

    Imaging, in particular magnetic resonance imaging (MRI), has in recent years increasingly become a crucial tool for the diagnostics of inherited and acquired muscular diseases. The aim of imaging in neuromuscular disorders goes beyond the detection and quantification of degenerative muscular changes, such as fatty degeneration and includes recognition of very early signs of muscular pathologies presenting as muscular edema. Therefore, imaging is a valuable diagnostic method to support the clinical diagnosis and to narrow down the differential diagnoses, leading to specific additional diagnostic tests in order to establish the correct diagnosis. Although advances in MRI hardware and technology have led to a faster, more accurate and advanced image acquisition allowing whole body examination in a feasible fashion, the standardization of image acquisition and interpretation remains a challenge. The aim of this review article is to address the important and clinically relevant issues concerning the role of imaging of neuromuscular diseases in order to facilitate a good interdisciplinary management for the diagnostics and monitoring of neuromuscular diseases. (orig.) [German] Die Bildgebung, insbesondere die Magnetresonanztomographie (MRT), hat in den letzten Jahren zunehmend an Bedeutung fuer die Diagnostik angeborener und erworbener Muskelerkrankungen gewonnen. Die Bildgebung ist dabei nicht nur in der Lage, Muskeldegeneration (z. B. fettige Degeneration) zu erfassen und zu quantifizieren, sondern auch sehr fruehe Stadien von Muskelerkrankungen mit dem Nachweis von oedematoesen Muskelveraenderungen zu erkennen. Die Bildgebung ist somit eine wertvolle diagnostische Modalitaet, um die klinische Diagnose zu unterstuetzen, die Differenzialdiagnose einzugrenzen und somit eine zielgerichtete weiterfuehrende Diagnostik zu ermoeglichen. Obgleich die technischen Weiterentwicklungen, insbesondere der MRT, eine schnellere, genauere und erweiterte (z. B. Ganzkoerperuntersuchungen) Bildakquisition erlaubt, bleibt die Standardisierung eine grosse Herausforderung. Der Bedarf einer angemessenen Standardisierung schliesst auch die Bildanalyse und -interpretation mit ein. Ziel dieser Uebersichtsarbeit ist es, wichtige, fuer Radiologen wie fuer Neurologen klinisch relevante Punkte der neuromuskulaeren Bildgebung zu benennen, welche wichtige Voraussetzungen fuer ein gutes interdisziplinaeres Management in der Diagnostik und Verlaufsbeobachtung neuromuskulaerer Erkrankungen sind.

  17. The Bramsche-Massiv anomalies - again an open question?; Die Anomalien vom Bramsche - wieder eine offene Frage?

    An unsolved problem of regional geoscientific importance for Northern Germany is the question of the existence of the so-called 'Bramsche Massiv'. The high thermal maturity in the southern area of the Lower Saxony Basin, the CO{sub 2}-risk and missing reservoir properties are being regarded as an aftermath of this massif, that is supposed to have risen in the Upper Cretaceous period as mafic pluton at depths of about 6 km. The existence of a massif of similar nature, located between Schleswig-Holstein and Brandenburg and characterised by gravimetric and magnetic anomalies, the so-called 'East-Elbian Massiv', has in the meantime been credibly challenged. The anomalies lie in the area of the eastern centre of the Southern Permian Basin and are particularly distinct due to the local maxima of Pritzwalk in Northwest Brandenburg. The causes of the observed anomalies in the Pritzwalk area are no longer assumed to arise from depths of 6-10 km, but in accordance with more recent geophysical investigations arise in all probability from the lower crust at a depth of between 15 and 30 km. Furthermore, the analysis of the thermal development of the Lower Saxony Basin close to the 'Bramsche Massiv' demonstrated that the level of maturities along well holes is more likely to be explained by an increased subsidence rate with subsequent tectonic inversion and not due to the effect of an intrusion. An alternative and comparative interpretation of other co-existent geophysical and geological anomalies also coincides with the current prevailing interpretation challenging the existence of the 'Bramsche Massiv'. If this intrusion in the suspected form never existed, the regional CO{sub 2}-risk would have to be reassessed, the structural and thermal development of the southern edge of the Lower Saxony Basin would need to be judged differently and the existence of available and possible Mesozoic and Paleozoic gas reserves in the neighbouring areas would need to be reevaluated.

    With its decision taken on 21. October 2014 (Az.: 2 BvE 5/11) the Federal Constitutional Court (BVerfG) decided during court proceedings between administrative bodies on the scope and limits of the parliamentary right of information. Even though the proceeding did not deal with nuclear exports but arm exports, foreign trade law, however, does not only designate an export licence obligation for military weapons but also for so called dual-use goods meaning goods, which can be used both for friendly as well as for military purposes. The export of these goods requires according to the so-called Dual-Use Regulation (EG) 428/2009 a licence. Annex I category 0 of the regulation (EG) 428/2009 lists a variety of nuclear materials, plants and equipment items for which this licence applies. In the same manner as arm exports, also exports of nuclear dual-use goods are being discussed in a special cabinet committee, the Federal Security Council (BSR), which shall coordinate cross-departmentally the German security and defence policy under consideration of economic interests and which categorises its results, according to the rules of procedure, as confidential. Also legally not regulated but common ''preliminary enquiries'' at the responsible Federal Ministry or rather Federal Office of Economics and Export Control by companies which plan an export and want to affirm the general approval for their export business prior to conclusion of contract take not only place for arm exports but also for nuclear dual-use goods. The decision by the Federal Constitutional Court can be applied to consultations about the authorisation of nuclear dual-use goods.

  5. Electron beam based transversal profile measurements of intense ion beams; Elektronenstrahl-Diagnostik zur Bestimmung vom transversalen Profil intensiver Ionenstrahlen

    Energy Technology Data Exchange (ETDEWEB)

    El Moussati, Said

    2014-11-03

    A non-invasive diagnostic method for the experimental determination of the transverse profile of an intense ion beam has been developed and investigated theoretically as well as experimentally within the framework of the present work. The method is based on the deflection of electrons when passing the electromagnetic field of an ion beam. To achieve this an electron beam is employed with a specifically prepared transversal profile. This distinguish this method from similar ones which use thin electron beams for scanning the electromagnetic field [Roy et al. 2005; Blockland10]. The diagnostic method presented in this work will be subsequently called ''Electron-Beam-Imaging'' (EBI). First of all the influence of the electromagnetic field of the ion beam on the electrons has been theoretically analyzed. It was found that the magnetic field causes only a shift of the electrons along the ion beam axis, while the electric field only causes a shift in a plane transverse to the ion beam. Moreover, in the non-relativistic case the magnetic force is significantly smaller than the Coulomb one and the electrons suffer due to the magnetic field just a shift and continue to move parallel to their initial trajectory. Under the influence of the electric field, the electrons move away from the ion beam axis, their resulting trajectory shows a specific angle compared to the original direction. This deflection angle practically depends just on the electric field of the ion beam. Thus the magnetic field has been neglected when analysing the experimental data. The theoretical model provides a relationship between the deflection angle of the electrons and the charge distribution in the cross section of the ion beam. The model however only can be applied for small deflection angles. This implies a relationship between the line-charge density of the ion beam and the initial kinetic energy of the electrons. Numerical investigations have been carried out to clarify the application range of the EBI diagnostic method and to benchmark the theoretical model. To achieve this goal a code has been developed in the programming language Python. Different charge distributions were considered and the simulation results have been compared with the theoretical model. The numerical investigations have shown a very good agreement with the theoretical model for deflection angles up to 20 mrad. This value defines the limit for the applicability of the theoretical model. Moreover, the magnetic field of the ion beam has also been taken into acount in the simulations. The results show that at high ion beam currents - starting at about 1 A - the electrons experience a non-negligible displacement along the ion beam axis, which has to be taken into consideration in experiments with intense heavy ion beams. The electrons suffer practically the same displacement under the influence of the magnetic field, regardless of their offset. At an offset of 10 mm the deviation from the shift at the ion beam axis is less than 3 %. For the experimental investigations of the EBI diagnostic method an offline experiment had been set up at the HHT experimental area at GSI in Darmstadt. The Coulomb field of the ion beam had been simulated by electrostatically charged wires. In case of a single wire, the experimental results are in good agreement with the theoretical model for deflection angles up to 20 mrad. This confirms the results of the numerical studies. To simulate the field within an ion beam, several wires have been clamped parallel to each other within a plane perpendicular to the electron beam. The electrons thus could pass through the spaces between the wires. The results of this experiments have quantitatively confirmed the prediction of the theoretical model that the derivative of the deflection angle with respect to the offset is proportional to the charge distribution in the cross section of the ion beam. Quantitatively, however, deviations from the theoretical model have been observed, which can be explained by the imprecise modelling of the charge distribution of an ion beam by the charged wires. The EBI diagnostic method has been applied for the first time in collaboration with the group of Professor Ulrich Ratzinger at the FRANZ accelerator at the Goethe University Frankfurt am Main for low-energy, DC ion beams - {sup 4}He{sup +} at 13.5 keV and a current of approximately 1 mA. The transverse charge distribution of these beams has been successfully determined by this diagnostic method. However the maximum deflection angle of the electrons was nearly 1/3 of the one predicted by the theoretical model. When employing an electron filter located along the ion beam line before the diagnostic chamber an increase of the deflection angle was observed. This suggests that electrons are generated by collisions of ions with background gas in such an amount, that they strongly influence the electrostatic field of the ion beam. This fact has to be more closely investigated in the future.

According to the authors, the new research programme will not only include activities in the small hydropower area, but rather all aspects of hydropower usage, including dams and large hydropower stations. The results of a survey made concerning research and further education in the hydropower area are discussed. These results formed the basis of the new concept. The report also presents a review of the present situation with regard to hydrological questions and dams as well as mechanical and electrical equipment. The education and training of professionals is looked at and national and international co-operation in the hydropower area is also discussed. Future developments are looked at, as are the economic aspects of the use of hydropower. Measures to be taken in the research area are proposed.

    By means of classical physics the tunnel effect is not explainable. Therefore the nature uses a trick from quantum mechanics: Particles, which possess no sufficient energy to overstep a barrier, ''tunnel'' simply through it. On this principle base both the nuclear decay and the heat-giving nuclear fusion in the sun and many further phenomenas of physics. Experimental studies recently showed that the particles tunnel thereby faster than light spreads in the vacuum. The ''mount to be tunneled through'' behaves thereby as a space without time. Is by this Einstein's theory of relativity disproved? Or even the causality principle violated? Answers give the authors in this draft on superluminal phenomena.

    The third Ministerial Conference of the World Trade Organisation (WTO) took place in Seattle (USA) from November 30{sup th} to December 3{sup rd} 1999. WTO members failed to agree on an agenda for a new round of trade-negotiation that should also include environmental and sustainability aspects. The Seattle Ministerial Conference provoked massive protests from non-governmental organisations (NGO) dealing with environment and development issues. They see the GATT/WTO regime - and globalisation in general - as a threat to their concerns. Against this background, the study analyses possibilities for the integration of environmental and sustainability aspects into upcoming WTO-negotiations. The focus is on views and proposals from international NGOs and critical scientists. First, the study deals with current and potential future areas of conflicts between environmental and trade policies. Furthermore, the environmental aspects of trade liberalisation in specific sectors and regulatory fields are discussed, which are currently negotiated in the WTO (agriculture, services) or which should be included in further negotiations (forest products, investment, etc.). The study moves on to an account of the WTO-Conference in Seattle from an environmental perspective and demonstrate a multitude of factors contributed to the failure of the conference. (orig.) [German] Vom 30.11. bis 03.12.1999 tagte in Seattle (USA) die 3. Ministerkonferenz der Welthandelsorganisation (WTO). Sie scheiterte bei dem Versuch, eine Einigung ueber die Agenda fuer eine neue WTO-Verhandlungsrunde herbeizufuehren, die auch Umwelt- und Nachhaltigkeitsaspekte einschliessen sollte. Die Konferenz stand unter dem starken Eindruck massiver Proteste von zahlreichen Umwelt- und Entwicklungsorganisationen, die im GATT/WTO-Regime - sowie grundsaetzlich in der Globalisierung - eine Bedrohung fuer Umwelt- und Nachhaltigkeitsanliegen sehen. Vor diesem Hintergrund untersucht die Studie die Moeglichkeiten einer

    Full Text Available Die vorliegende Arbeit bildet einem Teil der Studien, die unter Leitung des nationalen Malaria-Dienstes in Zusammenarbeit mit Technikern des Institutes Oswaldo Cruz im Sueden Brasiliens durchgefuehrt werden und sich mit dem Problem des Wechselspiels zwischen Malaria und Bromeliacen befassen. Die verfasser bearbeiten in dieser Niederschrift, die den Anfang einer Serie ueber die erwaehnten Fragen darstellt, die Entwicklung der Anophelinen der Untergattung Kerteszia in den Wasseransammlungen der Blattwinkel von Bromelien. Es wurde das Munizip Brusque ausgewaehlt, da hier die Abhaengigkeit der Bevoelkerung vom Wald eine sehr enge ist und da dieses Gebiet fuer die Oekologie und Topographie der Suedregion charakteristisch ist. Den hier gefundenen Wald nennen die Autoren die “Suedbrasilianische Regenformation”. Vor der Ankunft der Arbeitsgruppe wurden die folgenden Methoden zur Bekaempfung der Brutstaetten der Malariauebertraeger angewendet: 1. Manuelle Entfernung der Bromelien aus den die Staedte umgebenden Waeldern, 2. Abholzung. Da diese beiden Methoden zu drastisch sind, benutzten die erwaehnten Techniker anfangs eine 0,5% ige Loesung von Kupfersulfat als “Bromelicid” und spaeter PariserGruen, das vom Flugzeug aus verstaeubt wurde. Um ueberfluessige Schaeden an den Pflanzengesellschaften zu vermeiden, wurde daran gedacht, auf Grund oekologischer Betrachtungen das Problem “Bromeliaceae-Malaria” nach dem Vorbild Pittendrigh’s in Trinidad zu loesen. Es wurde folgenden Arbeitsplan durchgefuehrt: 1. Studium der Vergesellchaftungen im Hinblick auf die Soziologie und ihre Beziehungen zu den Bromelien, 2. Auszaehlung der in den Bromelien enthaltenen Larven und Puppen, 3. Kenntnis des Mittelwertes der Larven, die sich zu Imagines entwickeln und 4. Mikrolima der Waelder usw.

    The contribution presents first results and activities funded by the BMBF, the MSWWF of Nordrhein-Westfalen, and the RWTH Aachen. The main component of the Dorsten plant is the pressure chamber which was designed and constructed in close cooperation with Messrs. L. und C. Steinmueller. The combustion chamber was installed inside the pressure vessel of the former pressurized fluidized bed steam generator of the heating power station of the RWTH Aachen. The combustion chamber is designed for a thermal power of 400 kW, corresponding to a coal mass flow of about 50 kg/h, at a pressure of 12 bar and temperatures up to 1700 degrees centigrade in melting chamber operation. It is vertical, with an inner diameter of about 400 mm, an axially movable roof burner, and four points for optical access.

    For practical conditions one can find currents in underground electrical conductors like cable coverings earthed on both sides. As an example these currents are due to the alternating current system of the railroad or to the alternating current system of a Peterson coil, that tries to find a minimum resistance way from the transformer station to the place of the earth fault. Currents like these create a series voltage in the cable by inductive coupling. The voltage depends on the type and the length of the cable. The series voltages of all three phases form a zero sequence system. Taking into consideration that two cable systems running parallel to another, under certain circumstances it is possible to achieve a circulating zero sequence current. Additionally there is a shift voltage between the neutral point and the earth in the case of an earth fault in another place in the grid. The combination of these two factors can cause a malfunction of the earth fault detecting relays that are assigned to the parallel cable system. (orig.) [Deutsch] Im Erdreich vorhandene elektrische Leiter, z.B. die beidseitig geerdeten Schirme von Energiekabeln, werden in der Praxis nicht selten von Stroemen beaufschlagt. Dabei kann es sich z.B. auch um den Wechselstrom einer Petersenspule, der sich im Erdschlussfall einen widerstandsminimierten Weg vom Umspannwerk zur Fehlerstelle sucht, handeln. Ueber induktive Einkopplung entsteht im Leiter des Kabels eine Laengsspannung. Deren Hoehe ist vom Kabeltyp und der Kabellaenge abhaengig. Liegt als Netzkonfiguration eine Doppelleitung vor, die parallel betrieben wird, so koennen sich unter gewissen Randbedingungen kreisende Nullstroeme ausbilden. Diese wiederum koennen bei Vorhandensein einer Verlagerungsspannung zu einem Fehlansprechen von wattmetrischen Erdschlussrichtungsrelais fuehren. (orig.)

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

    On a company ground in Vorchdorf, Austria, from the 23{sup rd} to 26{sup th} of July 1996 an air-sparging experiment has been carried out as a supporting measure to a running redevelopment of an LCKW-contamination case. On this occasion compressed air, from which the oil had been extracted, was blown into the contaminated aquifer through a well with a maximum excess pressure of 0,6 MPa. The blowing-in of compressed air caused a mobilisation of the harmful substances in the ground water and the soil air. As a result circa 2,7 kg LCKW could be removed from the underground through neighbouring ground water and soil air wells. For the observed period of time this meant a tripling of the rate of discharge. On the basis of the obtained data we suggested a routine interval of blowing in compressed air into the well 1516. A blowing-in of compressed air into the highly contaminated wells 1617 and 1625 can not be realised until the construction of upstream situated injection wells, because of the danger of an uncontrollable spread of the harmful substances. (orig.) [Deutsch] Auf einem Firmengelaende in Vorchdorf, Oesterreich, wurde vom 23.07. bis 26.07.1996 ein Air-Sparging-Versuch als unterstuetzende Massnahme zur laufenden hydraulisch-pneumatischen Sanierung eines LCKW-Schadensfalles durchgefuehrt. Hierbei wurde entoelte Druckluft ueber einen Brunnen mit einem maximalen Ueberdruck von 600 mbar in den kontaminierten Aquifer eingeblasen. Die Drucklufteinblasung fuehrte zu einer Mobilisierung von Schadstoffen im Grundwasser und in der Bodenluft, so dass ueber benachbarte Grundwasser- und Bodenluftfoerderbrunnen ca. 2,7 kg LCKW aus dem Untergrund entfernt werden konnten. Fuer den Beobachtungszeitraum bedeutet dies eine Verdreifachung des Schadstoffaustrags. Aufgrund der gewonnenen Daten wird ein routinemaessiger Intervallbetrieb der Drucklufteinblasung in einen der Brunnen vorgeschlagen. Fuer zwei kontaminierte Brunnen ist eine Drucklufteinblasung wegen der Gefahr einer

Fuer verschiedene Immissions-Szenarien (Nuklidspektren fuer zwei Freisetzungsarten, fuer nasse und fuer trockene Ablagerung und fuer drei Zeitpunkte im Jahr) wurden die Unsicherheiten in Modell-Inputparametern, d.h. Messwerten und radiooekologischen Parametern durch subjektive Wahrscheinlichkeitsverteilungen ausgedrueckt. Die daraus resultierenden Verteilungen der Outputgroessen wurden mit Monte Carlo Simulationen bestimmt. Die Ergebnisse der Unsicherheits- und Sensitivitaetsanalyse haengen im allgemeinen von dem betrachteten Immissions-Szenario ab. Die groessten Beitraege zur Unsicherheit der berechneten Groessen kamen in den meisten Faellen von Messwerten (insbesondere der in-situ Messung der Bodenaktivitaet) und vom Aktivitaetstransfer vom Futter zum Nahrungsmittel. Im Fall der nassen Deposition kommen die Unsicherheiten von Parametern hinzu, die zur Bestimmung des Interzeptionsfaktors (Anteil der nass deponierten Aktivitaet, der vom Plfanzenbestand zurueckgehalten wird) dienen. Die an Mess-Stationen der Gammadosisleistung fehlende Information ueber Niederschlaege macht die Aussagen auf Kreisebene sehr unsicher.

    Council Directive 96/61/EC of 24/09/1996, which deals with integrated pollution prevention and control (IPPC Directive), aims for a high standard of protection for the environment as a whole: thus, it makes the construction of large industrial plants contingent on an integrated licensing procedure with public participation. Determining emission limit values on the basis of the best available technology (BAT) forms the core element of the licensing procedure. The requirements of the IPPC Directive are to be transposed into national law by 30/10/1999. To provide a framework for Article 16 (2), the European Commission has swiftly and purposefully organised an exchange of information for determining what is to be considered the best technology available. This has involved the preparation of BTA instruction sheets for industrial sectors affected by the IPPC Directive. This paper reports on the organisational structure and content of the information exchange accompanying the preparation of the BAT instruction sheets. It also provides information on the goals and organisation of the German contribution, in which the Federal Environmental Office plays a pivotal role as ''National Focal Point''. [German] Die Richtlinie 96/61/EG des Rates vom 24.09.1996 ueber die integrierte Vermeidung und Verminderung der Umweltverschmutzung (IVU-Richtlinie) zielt auf ein hohes Schutzniveau fuer die Umwelt als Ganzes; sie verlangt fuer grosse Industrieanlagen eine integrierte Genehmigung mit Oeffentlichkeitsbeteiligung. Kernelement der Anlagengenehmigung ist die Festlegung von Emissionsgrenzwerten auf der Grundlage der Besten Verfuegbaren Techniken (BVT). Die Anforderungen der IVU-Richtlinie sind bis zum 30.10.1999 in nationales Recht umzusetzen. Die Europaeische Kommission hat fruehzeitig und zielstrebig zur Ausfuellung von Artikel 16(2) im Hinblick auf die Ermittlung der Besten Verfuegbaren Techniken einen Informationsaustausch organisiert.

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

    The new concept of German Railways will in future be based on two types of train: the ICE 2.2, a high speed train with speeds of up to 330 km/hour and the ICT with a maximum speed of 230 km/hour. For the ICT, the number of carriages can be matched to the demand. The ICE and ICT are driven by 3 phase AC motors. The construction and method of operation of the drive are explained. Apart from the so-called electrical brakes and the disk brakes known from car construction, the eddy current brake is used as a further braking system. An electromagnet situated above the rail has DC flowing through it for braking purposes. Eddy currents are caused by this, which have a braking effect. (BWI) [Deutsch] Das neue Konzept der Deutschen Bahn wird sich in Zukunft auf zwei Zugtypen stuetzen: der ICE 2.2, ein Hochgeschwindigkeitszug bis zu 330 km/h und der ICT mit einer Hoechstgeschwindigkeit von 230 km/h. Beim ICT kann die Anzahl der Wagen dem bedarf angepasst werden. ICE und ICT werden von Drehstrom-Fahrmotoren angetrieben. Aufbau und Funktionsweise des Antriebes werden erlaeutert. Neben der sog. elektrischen Bremse und den vom Automobilbau her bekannten Scheibenbremsen wird als weiteres Bremssystem die Wirbelstrombremse eingesetzt. Hierbei wird ein ueber der Schiene angeordneter Elektromagnet zum Bremsen von einem Gleichstrom durchflossen. Es entstehen dadurch Wirbelstroeme, die eine bremsende Wirkung haben. (BWI)

    The constraints of PSA are increasingly considered with increasing application of PSA for the safety management of nuclear power plants (see US-NRC, 'Risk Informed Regulation', NRC-1). There is a vivid international discourse about the applicability of the variables of plant management and organisation in PSAs, which has lead to a great variety of research activities into this matter (see PSAM 4).

    The book addresses students of science and engineering, engineers and practicians in research and industry who are interested in temperature measurements and thermal processes in the temperature range between a few K and over 3200 K. For the first time ever, temperature sensors are classified on the basis of heat transport and heat transfer to the sensor as related to the technological aspects of sensor stress. This includes physical and materials-related fundamentals, materials selection, sensor design and optimisation, error analysis, as well as the analysis of economically relevant applications of electrical temperature measurement in thermal processes. [German] Dieses Buch wendet sich an Studenten der Natur- und Technikwissenschaften, Ingenieure und Hochschulabsolventen in der Forschung und Industrie, die sich mit Temperaturmessungen und thermischen Prozessen im Temperaturbereich von wenigen Kelvin bis zu ueber 3200 K befassen. Der neue Titel wird sich gegenueber bekannten Standards auf diesem Gebiet dadurch auszeichnen, dass eine Klassifizierung der Temperaturfuehler abhaengig vom Waermetransport und den Waermeuebergaengen zum Sensor in Verbindung mit den technologischen Aspekten zu den konkreten Beanspruchungen der Fuehler in der Anwendung vorgenommen wird. Dieser hohe Anspruch schliesst physikalische und werkstoffwissenschaftliche Grundlagen zur Systemloesung, der Werkstoffauswahl, zur Auslegung und Optimierung des Fuehlerdesigns und der notwendigen Fehlerbetrachtung ebenso ein, wie die Analyse volkswirtschaftlich bedeutsamer Anwendungen der elektrischen Temperaturmesstechnik in thermischen Prozessen.

    The measurements were initiated by the city of Essen as residents in the vicinity of a metallurgical plant at Essen-Kray complained about high pollution levels, especially caused by shredder systems in which scrap aluminium, electric circuits, metal parts, and electric motors are processed. Measurements focused on heavy metals in airborne dust, polychlorinated biphenyls, dioxins and furans. Essen-Kray was found to have higher pollutant levels than other sites in the Rhine-Ruhr region. While the continuously measured inorganic and organic pollutants were below limiting values, concentrations of airborne dust were enhanced, concentrations of heavy metals in airborne dust were high, and PCB concentrations were very high. [German] Von April bis Juni 2000 wurde in Essen-Kray eine MILIS-Messung durchgefuehrt. Die Messung wurde vom Amt fuer Umweltschutz der Stadt Essen beantragt. Der Stadt Essen liegen Beschwerden von Anwohnern eines metallverarbeitenden Betriebes in Essen-Kray ueber hohe Immissionen, hauptsaechlich beim Betrieb von Schredderanlagen, in der Aluminiumschrott, Schalter- und NE-Metallschrott sowie Elektromotoren verarbeitet werden, vor. Der Schwerpunkt der MILIS-Messung lag in der Bestimmung der Schwermetalle im Schwebstaub, der polychlorierten Biphenyle, der Dioxine und Furane. Die MILIS-Messung in Essen-Kray zeigt, dass es sich hier um einen im Vergleich mit anderen Standorten im Rhein-Ruhr-Gebiet staerker belasteten Standort handelt. Waehrend die kontinuierlich gemessenen anorganischen und organischen Schadstoffe unauffaellige Werte aufwiesen, traten bei Schwebstaub erhoehte, bei den Schwermetallen im Schwebstaub hohe und bei den PCB im Vergleich sehr hohe Konzentrationen auf.

    This thesis presents the results of an experimental study of passive flow control in a highly loaded compressor cascade. Vortex generators and boundary layer fences are used as flow control devices in order to enhance the aerodynamic performance. In a first step, the complex secondary flow effects in the compressor cascade are described in detailed. This gives the basis for a specific approach of influencing the cascade flow by means of vortex generators and boundary layer fence arrangement on the endwall. Depending on the vortex generator type and position, there is an impact on the endwall cross flow, the development of the horse shoe vortex at the leading edge of the vane and the extent of the corner separation achieved by improved mixing within the boundary layer. The designed boundary layer fence arrangement on the endwall constrains the interaction of the endwall cross flow with the suction side boundary layer, thus the onset of the corner separation is delayed and a significant loss reduction achieved. In order to proof the cascade results, an exemplary vortex generator configuration is applied on the stator of a single stage axial compressor and a significant efficiency enhancement is achieved.

  19. On the relation of the theoretical foundations of quantum theory and general relativity theory; Ueber die Beziehung der begrifflichen Grundlagen der Quantentheorie und der Allgemeinen Relativitaetstheorie

    Kober, Martin

    2010-07-01

    The specific content of the present thesis is presented in the following way. First the most important contents of quantum theory and general relativity theory are presented. In connection with the general relativity theory the mathematical property of the diffeomorphism invariance plays the deciding role, while concerning the quantum theory starting from the Copenhagen interpretation first the measurement problem is treated, before basing on the analysis of concrete phenomena and the mathematical apparatus of quantum theory the nonlocality is brought into focus as an important property. This means that both theories suggest a relationalistic view of the nature of the space. This analysis of the theoretical foundations of quantum theory and general relativity theory in relation to the nature of the space obtains only under inclusion of Kant's philosophy and his analysis of the terms space and time as fundamental forms of perception its full persuasive power. Then von Weizsaeckers quantum theory of the ur-alternatives is presented. Finally attempts are made to apply the obtained knowledge to the question of the quantum-theoretical formulation of general relativity theory.

    The medical management and counseling of persons at high risk due to exposure to chemicals or radiation or due to personal disposition, present an additional challenge for physicians and especially radiologists involved. This article is based on own experiences with patients who had been exposed to Thorotrast. They had been injected with the contrast medium Thorotrast, which was in use world-wide until around 1950. Thorotrast caused a chronic alpha irradiation mainly of the liver (up to 0.4 Gy/a), spleen (1.2 Gy/a) and bone marrow (0.1 Gy/a). For the Thorotrast patients and their physicians the most worrying problem was the risk of primary malignant liver tumors which occurred in more than 20% of the exposed persons, i.e. 100 times more frequently than in a non-exposed control group. The medical and especially radiological experiences with the management of these patients summarize a general aspect of the problem and can be referred to when managing other high risk groups. (orig.) [German] Die aerztliche Fuehrung von Personen, die noch nicht erkrankt sind, aber ein deutlich hoeheres Risiko fuer bestimmte Tumorerkrankungen aufgrund exogener oder endogener Ursachen haben, stellt den Arzt und speziell den diagnostischen Radiologen vor neue Herausforderungen. Dem Beitrag zugrunde liegen die Erfahrungen bei der Betreuung und Beratung so genannter Thorotrastpatienten, d. h. Personen, die nach lange zurueckliegender (vor 1950) intravasaler Injektion eines weltweit eingesetzten Roentgenkontrastmittels zeitlebens einer Alphastrahlung v. a. der Leber (bis 0,4 Gy/a), der Milz (1,2 Gy/a) und des Knochenmarks (0,1 Gy/a) ausgesetzt waren. Fuer die Thorotrastpatienten und die Aerzte stand im Vordergrund die Sorge der Entstehung primaerer, maligner Lebertumoren, die bei mehr als 20% der Betroffenen und damit im Vergleich zu einer Kontrollgruppe 100-fach haeufiger auftraten. Die allgemeinen aerztlichen und speziell radiologischen Erfahrungen sind grundsaetzlicher Art und lassen sich auf den Umgang mit anderen Hochrisikogruppen uebertragen. (orig.)

    The atmospherical cloud fields in the mesoscale and the synoptic scale are studied and classified with respect to brightness, form, structure, horizontal and vertical dimension, and surface temperature on the basis of satellite observations. The different developing stages and the drift of the clouds are analysed by satellite measurements; which give insight into the atmospheric processes, improving the possibilities for predictions. The wind velocities in the higher troposphere are of particular interest for civil aviation. The world climate program takes profit from the covering statistics of the cloud fields, and from measurements of the surface temperature, covering the continents and the sea. Such measurements can be performed by satellite-born radiometers, e.g. also with Meteosat. The surface radiation temperature distributions are the initial data for climate models aiming at climate predictions for the human society on a time scale of several years. Models describing the circulation in the atmosphere and in the sea as well as in the boundary region in between can be considered as a first step in this direction. Several reports are dedicated to the role of the radiation budget for the simulation and description of such physical processes. The changes of the radiation budget components in space and time as well as the resulting meteorological effects, in particular the number and the properties (first of all radiation temperature and albedo) of the clouds have an essential influence on the calculation of the radiation fluxes and divergencies in different layers of the atmosphere. Abstracts are available for 59 papers of this conference report.

  4. Application of a complex transport problem for simulating an acid rain episode in Europe. Anwendung eines komplexen Ausbreitungsmodells zur Simulation einer Episode saurer Deposition ueber Europa

    For the first time in Europe, a comprehensive Eulerian regional tropospheric transport, transformation and removal model has been applied to an european wide acid deposition episode. This model, the Transport And Deposition of Acidifying Pollutants (TADAP) model incorporated detailed knowledge of the relevant physicochemical processes which lead to the formation of photochemical oxidants and acidifying pollutants. The EUROPA-model (EUM) of the German Weather Service, a limited area numerical weather prediction model, has been used to derive the total meteorological cloud variables. The application of the EUM/TADAP-modelling system to a 20 day-wintertime acid deposition episode in Europe showed that it is possible to model the principal features of the acid deposition system. In general, there is reasonable agreement between observed and predicted concentration and deposition patterns. Most discrepancies from observed trends can be explained by deviations between the modelled and the actual meteorology. First sensitivity studies with TADAP directed to reveal the influence of emission changes on the acid deposition system showed that there are considerable non-proportionalities between depositions of secondary pollutants and the emissions of the respective precursors. The nonlinearities arise due to the chemical coupling of the SO{sub x}/No{sub x}/VOC-system. This makes the design of control strategies to a highly complex task. Strategies developed to tackle different air pollution problems can therefore not be looked upon independently. (orig.) With 47 refs., 42 figs.

    The concentrations and deposition of atmospheric trace substances were measured over the Kiel Bight and the Southern North Sea. A European longrange-transport model was used to calculate the atmospheric concentrations of trace metals and their deposition into the North Sea and the Baltic Sea. Natural and anthropogenic emitted element concentrations could be separated definitely by the measurements, and preferred transport directions of anthropogenic contributions could be found. Concentrations measured over the North Sea could be related to the surrounding emission areas by airmass trajectory analyses. The deposition measurements show that the main removal process is due to deposition by precipitation. Calculated and measured concentrations at several receptor points agreed well. The model results confirm the dominating role of wet deposition. It could be shown that extrapolations from measurements at coastal stations to the whole sea area tend to overestimate the total deposition into North Sea and Baltic Sea. (orig.)

    The efficiency of a combined power/heat plant is treated in an example relating to a gas turbine. An important prior condition for optimum planning of a combined power/heat plant is assessment of the current position in addition to a demand analysis. Constituting a vital planning instrument for the process are systematic annual continuous curves in respect of electricity and heat. Aided by a PC software program it is possible, on the basis of a few key figures, to establish whether a detailed study is able to bring about any economical solution. In addition, a primary-energy and emission balance-sheet is compiled illustrating the advantages to be gained from combined power/heat systems of relevance to the environment. A sensitivity analysis shows main influential factors exercised on the efficiency of the gas turbine project. As might be expected, the greatest influenc eon profitability comes from the electricity proceeds, the price of fuel and capital costs. Finally, different financing models for combined power/heat plants are discussed along with a price safeguarding method. (orig.) [Deutsch] Die Wirtschaftlichkeit einer KWK-Anlage wird am Beispiel einer Gasturbine erlaeutert. Wichtige Voraussetzung fuer die optimale Planung einer KWK-Anlage ist die Bestandsaufnahme mit Bedarfsanalyse.

    The objective of the project is establish on the basis of Round Robin tests the current state of efficiency of various, defined testing methods, so that required or achievable optimizations can be defined and made. The project work up to date encompasses mon-destructive examinations of 15 austenitic welds with nominal widths DN 150/200/250 and wall thicknesses from 8 to 18 mm. Except for one test piece, (elbow/elbow), the joining welds are straight pipe to elbow welds. The results of the Round Robin tests show that the NDE detection limits for the fault examined (intercrystalline stress corrosion cracking) are in the range assumed so far, i.e. from about 20 to 25% of the wall thickness to be examined. The defect detection rates of the ultrasonic test methods applied are approx. 70% and thus are about equal in achievement with comparable international Round Robin tests (PISC; ASME/PDI, ENIQ, etc.). Clearly better are the fault detection rates of radiography. Evaluation of the individual results indicates the detection limits can be improved, by 1. reducing the misalignment of edges, 2. grinding of welds, 3. avoiding sharp notches at the root, 4. producing coaxial surfaces. (orig./CB) [Deutsch] Ein Ziel des Vorhabens ist es, mit Ringversuchen den derzeitigen Stand der Leistungsfaehigkeit einzelner Pruefverfahren und -techniken zu erkennen, um moeglicherweise notwendige Optimierungen vornehmen zu koennen. Das Vorhaben umfasst bis jetzt zerstoerungsfreie Pruefungen an 15 austenitischen Naehten mit Nennweiten DN 150/200/250 und Wandstaerken zwischen 8 und 18 mm. Mit einer Ausnahme (Bogen/Bogen) handelt es sich um Verbindungen Geradrohr/Bogen. Die Ergebnisse des Ringversuches weisen darauf hin, dass die Nachweisgrenzen der ZfP fuer den vorliegenden Fehlertyp (Interkristalline Spannungsrisskorrosion) in der bisher schon angenommenen Groessenordnung von ca. 20-25% der geprueften Wanddicke liegen. Die Fehlerauffind-Raten der US-Pruefung liegen mit ca. 70% im Rahmen vergleichbarer internationaler Ringversuche (PISC; ASME/PDI, ENIQ usw.). Deutlich hoeher liegen die Fehlerauffind-Raten der Durchstrahlungspruefung. Die Betrachtung der Einzelergebnisse legt nahe, dass die Nachweisgrenzen verbessert werden koennen, und zwar durch 1. Reduzierung des Kantenversatzes, 2. Beschleifen der Decklage, 3. Vermeidung von scharfen Wurzelkerben, 4. Herstellung von koaxialen Oberflaechen. (orig./MM)

    Since forty years instruments onboard satellites have been demonstrated their usefulness for many applications in the field of meteorology and oceanography. Several experiments, like ERBE, are dedicated to establish a climatology of the global Earth radiation budget at the top of the atmosphere. Now the focus has been changed to the regional scale, e.g. GEWEX with its regional sub-experiments like BALTEX. To obtain a regional radiation budget for Europe in the first part of the work the well calibrated measurements from ScaRaB (scanner for radiation budget) are used to derive a narrow-to-broadband conversion, which is applicable to the AVHRR (advanced very high resolution radiometer). It is shown, that the accuracy of the method is in the order of that from SCaRaB itself. In the second part of the work, results of REMO have been compared with measurements of ScaRaB and AVHRR for March 1994. The model reproduces the measurements overall well, but it is overestimating the cold areas and underestimating the warm areas in the longwave spectral domain. Similarly it is overestimating the dark areas and underestimating the bright areas in the solar spectral domain. (orig.)

    Weldolets are positioned on many mineral oil pipelines. The following questions had to be clarified: do the existing connecting pieces stand up to the varying stresses; which service life can be expected; and are there any additional measures or tests to be initiated for a safe operation of mineral oil pipelines. The well-proven instructions of relevant regulations were compared and assessed. With their help, pipe-connections were recalculated by means of practical examples, and suggestions were made for an exchange of weldolets, if necessary. (orig.)

    Purpose: Retrospective analysis of the success and complication rates of chest port implantation via the lateral subclavian vein. Materials and methods: Between January 2003 and June 2004, the lateral subclavian vein in 271 patients (186 women, 85 men, mean age 53.2 years) was punctured guided by ultrasound. This access was used to insert a port system, and the catheter tip was placed at the cavoatrial junction. The port reservoir was implanted in a subcutaneous infraclavicular pocket and fixed to the fascia of the pectoralis muscle. Indications for port implantation were chemotherapy (n=239), total parenteral nutrition (n=2) and intravenous medication (n=30). The patient follow-up was mainly performed either by the oncology division of the department of gynecology or by the department of internal medicine. Results: A chest port catheter system was successfully implanted in all patients. The catheter remained in place for a mean duration of 269.4 days (SD 192.3 days). No complications occurred during implantation. In the post-interventional period, 6 catheter dysfunctions were found (thrombotic 0.09 per 1000 catheter days; mechanic 0.05 per 1000 catheter days). While one local infection occurred in the early post-interventional period, 3 local and 15 systemic infections were independent of the port catheter placement (0.39 per 1000 catheter days). The rate of port catheter explantations due to dysfunction or infection was 0.07 per 1000 catheter days. Conclusion: Ultrasound-guided puncture of the lateral subclavian vein is a safe procedure for the insertion of central venous port catheter systems and had a very low complication rate in our study. For further evaluation of our port placement technique, prospective studies compared to placement through the internal jugular vein are necessary. (orig.)

  16. On the reliability of thionyl chloride/lithium batteries. [Li/SOCl sub 2 -battery]. Ueber die Zuverlaessigkeit der Thionylchlorid-Lithium-Batterien

    1991-10-10

    Lithium batteries must be mentioned as the most sophisticated system for back-up functions, whose great advantage is the very low, self-discharge, ie: the stored energy is only consumed by the battery to a very small extent and is largely available for use. The normal working temperature is between -55 and +75deg C. Higher working temperatures are possible if one accepts a shorter service life, as the self-discharge rises more than proportionally. Some ideas are given on possible causes of failure, reliability tests, a complete qualification test, design test and final inspection. A specific failure definition, the concept of 'total quality' and non-destructive test methods are proposed in order to be able to check the reliability of the thionyl chloride/lithium battery in a better way.

    The retrieval of radioactive wastes and the closure of the repository Asse II is a very complex project: not only with respect to technical aspects but also with respect to public information. The information brochure no 29 edited by the Bundesamt fuer Strahlenschutz BfS is dealing with the rather philosophic questions knowledge and truth. The German expert on constitutional law Peter Bull answered to the question whether subjectively assumed health hazards could inhibit a reasonable solution: it has to be expected from the public to bear inconvenient truth. Clarification is necessary instead of wrong populism and suppression of obnoxious findings.

    The largest electricity consumption in municipal sewage treatment plants occurs during biological treatment. This fact has been the motivation for a closer look at the electricity consumption of three biological treatment processes that will be applied more frequently in the future. The wastewater treatment plants in Lyss (Fixed Bed Biological Reactor), Wohlen (Moving Bed Biological Reactor), and Waedenswil (Membrane Biological Reactor submerged in an activated sludge process) provided the basis for this analysis, which was done both in absolute terms as well as in relation to each plant's loading. The specific energy consumption of the Fixed Bed Reactor, averaging 20 - 25 kWh/p.e. per annum (p.e. = person equivalent), is comparable to the one of a conventional activated sludge process (benchmark/standard value = 23 kWh/p.e. per annum; optimal value 18 kWh/p.e. per annum). The Moving Bed Reactor uses less than 30 kWh/p.e per annum when working at or close to full capacity, and more than 40 kWh/p.e. per annum at low fill. The Membrane Biological Reactor submerged in an activated sludge process shows the highest specific energy consumption values (> 40 kWh/p.e. per annum). In order to be able to run the biological treatment at optimal electricity consumption levels, the plants should be designed in such a way as to automatically run on partial or intermittent mode in times of low waste load. Further implementation of these new biological purification processes will lead to an increase in electricity consumption unless the significant energy savings potential wastewater treatment plants still offer is tapped. In order to be able to exploit this potential, electricity consumption has to be considered as of equal relevance as treated effluent quality. (author)

    Isolectronic impurities and their impact on the properties of compound semiconductors is discussed in two systems: Nitrogen in Ga(As,P) quantum wells on the one hand and Sulfur and Selenium in bulk ZnTe. The properties are reduced to two experimentally observable aspects: Band Bowing, i.e. the non-linearity of the band gap of the compound semiconductor and disorder, i.e. in particular the formation of a strongly localized density of states beneath the fundamental band gap. Apart of the pure experimental studies an insight into the theoretical model of disorder-induced temperature dependent luminescence properties of the compound semiconductors by means of Monte Carlo Simulations is given.

    With the phase-out of nuclear energy, the consistent utilization of renewable energies increasingly is becoming important. Thus, the power supply performs a change in which the development of networks does not come along in part. At the same time, consumers of electric power also are producers. Instead of speaking about consumers, now one may speak about prosumers. In this context, the Smart Grid is on everyone's lips. Smart components are less common. Without smart components, smart grids are not feasible. Seemingly small components such as data radio modems can play an important role.

    In addition to the high-temperature superconductors, the so-called heavy fermion systems are among the most fascinating representatives of strongly correlated electron systems. Caused by the competition of Kondo effect, RKKY interaction and electrostatic crystal field effects these compounds reveal a wide variety of different ground state properties. For example, many of these systems are located in the vicinity of a magnetic instability. At such a quantum critical point a continuous transition between two states with different symmetry occurs at absolute zero temperature. Apart from the three classic tuning parameters (i) chemical substitution, (ii) hydrostatic pressure, and (iii) external magnetic field also the reduction of the effective spin degeneracy N, i.e. the reduction of the number of crystal field levels which are shielded by the Kondo effect seems to induce quantum critical behavior. The proximity to a quantum critical point together with an unusually high effective spin degeneracy of N=4 make the ternary 1-9-4 compound CeNi{sub 9}Ge{sub 4} the perfect starting system for experimental studies of this new parameter. For the first and so far only time such a scenario could be observed in the substitution series CeNi{sub 9-x}Cu{sub x}Ge{sub 4} (0≤x≤1). Extensive studies show that in this system quantum criticality is not only caused by the balance between Kondo effect and RKKY interaction but also by a reduction of the effective spin degeneracy. The results on the copper series provided the incentive to synthesize and analyze related systems with regard to quantum criticality in the scope of this work. The focus here was on the systems CeNi{sub 9}Ge{sub 4-x}Si{sub x}, CeNi{sub 9}Ge{sub 4-x}Ga{sub x}, CeNi{sub 9-x}Fe{sub x}Ge{sub 4} and CeNi{sub 9-x}Co{sub x}Ge{sub 4}. This thesis was methodologically supported by X-ray studies, theoretical LDA+U calculations and extensive thermodynamic and magnetic investigations on the macroscopic and microscopic level. Due to strong crystal field effects the systems under study reveal a high potential for interesting correlation physics with a wide range of different ground states. These range from a model-type Kondo lattice behavior in CeNi{sub 9}Si{sub 4} through a complex magnetic order in CeNi{sub 9}Ga{sub 4} up to the coexistence of two magnetic sublattices in the compound CeCo{sub 9}Ge{sub 4}. A quantum critical scenario, as it was found for the related copper series, could not be observed in any of the investigated systems. The reason for this can be attributed to differences in the Wyckhoff positions concerned with the individual substitutions. While the onset of nickel by copper substitution causes a continuous splitting of the N=4 ground state of the ternary compound CeNi{sub 9}Ge{sub 4} the systems in this work exhibit a sudden change of N and thus a suppression of possible quantum critical points. A final comparison of the various results clearly indicates that not the reduction of the effective spin degeneracy N but actually the crystal field has been experimentally demonstrated as a new tuning parameter for quantum criticality in CeNi{sub 9-x}Cu{sub x}Ge{sub 4} (0≤x≤1) and thus for heavy fermion systems.

    Adult mice were subjected to non-lethal wholebody irradiation with doses of 2.5 and 5.0 Gy. Non-irradiated animals served as controls. Following periods varying from one day to one year after irradiation, the animals were once administered endotoxin (LPS from S. abortus equi) using doses of 100, 200 or 400 [mu]g. Twelve to 48 hours following the single administration of endotoxin the animals were sacrificed and examined for changes to the liver, lungs, kidneys, small intestine and stomach. It was confirmed on a histological basis that the causes of death differed between irradiated and non-irradiated animals. The studies have shown that the responsiveness to endotoxin subsequent to irradiation was characterized by considerable fluctuations over time. Histology further provided evidence to prove that regenerative processes were in progress in the liver as well as the intestinal and gastric mucosae, with the number of differentiated cells determined here being lower than that of mitotic cells. To summarize it can be stated that wholebody irradiation with 2.5 Gy to 5 Gy in the course of weeks or months clearly adds to the damage already done by endotoxin. Conversely, irradiation a few days prior to administration of endotoxin provides protection against those damaging influences. (orig./MG)

    The influence of topography on the vertical exchange of trace elements was investigated with the aid of a numeric simulation model. It is a couopled 3D model consisting of the mesoscale model KAMM and the dispersion model DRAIS, extended by the gaseous phase mechanism of the RADM model. This way, both meteorological and chemical processes can be analyzed in a preselected time and spatial resolution. The simulations were validated by a comparison with measurements made during the TRACT campaign. Satisfactory agreement between the two was established. [German] In der vorliegenden Arbeit wurde der Einfluss der Topographie auf den vertikalen Austausch von Spurenstoffen mit Hilfe eines numerischen Simulationsmodells untersucht. Bei dem Simulationsmodell handelt es sich um ein dreidimensionales gekoppeltes Modell, welches aus dem mesoskaligen Modell KAMM und dem um den Gasphasenmechanismus des RADM-Modells erweiterten Ausbreitungsmodell DRAIS besteht. Mit diesem Modellsystem war es moeglich, sowohl meterologische als auch chemische Prozesse in einer vorher gewaehlten zeitlichen und raeumlichen Aufloesung zu betrachten. Um die Qualitaet der Simulation und damit deren Verwendbarkeit fuer die Untersuchungen festzustellen, wurde ein Vergleich mit Messungen durchgefuehrt. Dazu wurden berechnete meterologische und chemische Groessen mit den waehrend der Feldmesskampagne TRACT gemessenen Groessen verglichen. Der Vergleich der simulierten Groessen sowohl mit Radiosondenaufstiegen als auch mit Zeitreihen und Flugzeugmessungen lieferte eine gute Uebereinstimmung. (orig.)

    Objective: The effect of radiotherapy in context of a plantar fasciitis in order to reduce pain was evaluated in this retrospective study. Patients and methods: The data of 188 patients who suffered of heel spur pain and who were irradiated in the period from 1994 to 2009 were evaluated in this study. All of them had at least one follow up examination after radiatiotherapy. The mean age amounted to 57 years. 76.5% of the patients were female. All patients described a local pain which was the basis for the indication. 74.4 % of the patients described pain especially under stress. The duration of anamnesis was averaged as follows: 15 % of the patients had pain for some weeks to 3 months, 43 % for 4 to 6 months, 28% even for 7 to 12 months. The period of medical history was longer than 12 months for 12 % of the patients in this study. 122 of 188 patients received orthopedic arch support (shoe inlays) as first therapy method. Most of the patients were irradiated using regular lateral opposing fields with photons of the energy 4 MV and 6 MV of a linear accelerator, applying a total dose of 6Gy in 6 fractions to 1,0Gy twice weekly. Only one patient was irradiated using a Co{sup 60} machine. The acquisition of data regarding the effect was performed on the last day of the radiotherapy and in 3 to 6 monthly follow ups. Additionally the doctors who attended the patients beyond the radiotherapy received a special questionnaire about the pain reduction, so that the follow up data could be completed. Results: On the last day of radiotherapy 120/188 patients (63,8%)reported an improvement of pain reduction, 7/188 patients (3,7%) absence of pain. For 52/188 patients (27.6 %) pain remained constant. At the second follow up examination after in the median 100 days the effect of radiotherapy of 165 patients could be evaluated, 43/165 patients (26 %) were pain free, 79/165 patients (47,8 %) reported an obvious pain reduction, and for 33/165 patients there was no pain improvement. At the third follow up examination after in median 503 days there were data of 94 patients that could be used for our study, 22/94 patients (23,4 %) felt a pain reduction and 56/94 patients (59,5 %) were completely painless. At the fourth follow up examination after in median of 1170 days patient database included 37 statements about pain. For 4/37 patients (10,8%) there was a pain reduction and for 32/37 patients (86,4 %) an absence of pain. After in median of 1590 days the fifth follow up took place, this showed statements of 84 patients about their pain. For 72/84 patients (85,7 %) radiotherapy achieved a complete absence of pain, an obvious improvement with 9/84 patients (10,7 %). Only 3/84 patients (3,5 %) described a steady pain symptomatology. All these results for pain reduction of 182 patients were achieved nearly without side effects, only 5 patients reported a light flush in the irradiated area. Conclusion: The radiotherapy of the painful heel spur appears highly effective, long-lasting and side-effect-free regarding to pain relief. The effect occurs often several months after radiotherapy, as far as it can be evaluated in this retrospective setting based on partially incomplete follow up data. We could not identify any prognostic factors.

    In what way and to what extent does an event like the Chernobyl reactor accident influence the citizen's attitudes and political commitment. This book evolves a number of theses on these questions dealing above all with the determinants of political protest. Two investigations are presented in order to verify those theses: in 1982 and 1987 (some nine months after the Chernobyl reactor accident), the same persons were interviewed. In addition, representative surveys in the Federal Republic of Germany are analysed, in order to assess in general the impact of Chernobyl. From the contents: explanation model for political protest; Chernobyl effect: effect of critical events on the mobilization of political protest; discontent with nuclear energy use, political alienation and protest; internal incentives for protest: norms, readiness for aggression, and entertainment quality of protest; resources as determinants of political protest; sanctions and protest; social nets and political protest; verification of a central model of political protest, and problems encountered by research. Appendix: investigation plan and random sampling of the panel of nuclear power opponents. (orig./HP).

    The term ''leukemia'' encompasses a group of diseases with a variable clinical and pathological presentation. Its cellular origin, its biology and the underlying molecular genetic alterations determine the very variable and individual disease phenotype. The focus of this review is to discuss the most important guidelines to be taken into account when we aim at developing an ''ideal'' animal model to study leukemia. The animal model should mimic all the clinical, histological and molecular genetic characteristics of the human phenotype and should be applicable as a clinically predictive model. It should achieve all the requirements to be used as a standardized model adaptive to basic research as well as to pharmaceutical practice. Furthermore it should fulfill all the criteria to investigate environmental risk factors, the role of genomic mutations and be applicable for therapeutic testing. These constraints limit the usefulness of some existing animal models, which are however very valuable for basic research. Hence in this review we will primarily focus on genetically engineered mouse models (GEMMs) to study the most frequent types of childhood leukemia. GEMMs are robust models with relatively low site specific variability and which can, with the help of the latest gene modulating tools be adapted to individual clinical and research questions. Moreover they offer the possibility to restrict oncogene expression to a defined target population and regulate its expression level as well as its timely activity. Until recently it was only possible in individual cases to develop a murin model, which fulfills the above mentioned requirements. Hence the development of new regulatory elements to control targeted oncogene expression should be priority. Tightly controlled and cell specific oncogene expression can then be combined with a knock-in approach and will depict a robust murine model, which enables almost physiologic oncogene expression, subsequently mimics the human phenotype in detail and hence fulfills the requirements of an ''ideal'' animal model.

    ''Fascinating physics'' is a picturesque expedition through 140 themes of classical and modern physics. On each one double-page to the reader is thereby offered a compact access in each one theme: From the aurora until the black hole, from the particle accelerator until the GPS system, from the curved space-time until the supersymmetry, from the oscillating dipole until Foucault's pendulum - a large variety of themes is taken up and carefully explained. Thereby the special strength of the book lies in the clear language and the explanations get along mostly without formulas - accompanied by breathtaking pictures, which lead the beauty of our world in front of the eyes.

    Full Text Available Since the reign of Philip the Good, the combination of fire-iron, flint and fire has been used in the Duchy of Burgundy for symbolic purposes. On the founding of his Order of the Golden Fleece in the year 1430, the Golden Ram was added to create the symbol of the Order. The article sheds light on the way this symbolism was utilised within the iconography of the Dukes Philip the Good and Charles the Bold as well as the Emperors Maximilian I. and Ferdinand I. The motivation approaching and analysing this question arose out of the substantially unrecognized elitist usage and scale of implementation of this imagery under Ferdinand I. which never has been a subject of intense research so far. Compared to his predecessors, Ferdinand I. used these symbols in all his art procurement with exceptional concentration, especially on his residential architecture, i.e. the Belvedere in Prague, Bratislava Castle, and the Hofburg in Vienna. This had an enduring effect also on the art of his successors.

    The decision of the German parliament to gradually close down nuclear power plants mainly located in the south of Germany and to support wind farms in the North Sea mud flats as the dominant regenerative energy source requires the strengthening and enlargement of the power supply system with the installation of new long distance high voltage power lines. The legally fixed dimension and formality of the actual planning process are discussed as well as the legal regulations for the protection of human health. Guided by the assessment of IARC a ''possible'' carcinogenic effect of low frequency electromagnetic fields on people living in the vicinity of high voltage power lines has to be considered. Therefore from a preventive viewpoint the minimal distance of 400 m between newly planned high voltage power lines and human settlements required by law seem justified.

    The path to a mainly sustainable energy supply is predetermined by European and national directives. It is to be expected that the sustainable energy supply is growing much faster than the infrastructure can follow. Bottlenecks in the transmission system in particular by the development of onshore and offshore wind energy are probable. Also the expansion of photovoltaics in the settlements demands from the distribution networks. The idea of smart grids to store the excess energy in the superimposed classical energy system is negatively impacted by new problems. The micro grid expands the decentralized technology by allowing for temporary autonomy and energy balance especially if central storage systems and transmission capacities can not be used due to temporary bottlenecks. Concepts of decentralized supply are interesting that offer a temporary opportunity for a restricted island operation with reduced load.

    A monument-protected depot in Geislingen (Federal Republic of Germany) received a new utilization. The upper floors were rearranged to an office space. In the ground floor a room for events was developed. An open kitchen was developed in the adjacent former storage for artificial fertilizers. The historical charm of the building established in 1921 remained large - despite modern technical equipment, a decentralized energy management system and low-energy building standard.

    With the aim of investigating the moving of the power plant Peruca dam body, measurements with the classical precise theodolite WILD T3 as well as the modern electronic instruments, KERN E2 and WILD T2000S, were carried out in order to choose the most suitable instrumentaria. All three instruments were used in measuring with the same number of horizontal angle rounds; by using the statistical tests, a significant accuracy dependency on the used instrument type was established. The most accurate results were obtained by electronic theodolite Wild T2000S (estimated variance factor {sigma}=0.61), then by KERN E2 {sigma}=1.23, and finally by T3 {sigma}=1.68. Likewise, the use of the deformation analysis, i.e. global and local tests, the highest number of significant movements was established by measuring with the WILD T2000S electronic theodolite. The interior accuracy of straight line measurement of the electronic theodolite E2 was investigated in dependence with the number of horizontal angle rounds. Unfortunately, the war in this country is the reason that the planned measurements with the GPS devices have so far not been carried out. (orig.)

Der zweite Teil der Tagung ist nicht minder wichtig. Beim Passivhaus geht es im wesentlichen darum, Heizwaermeverluste im Winter so klein zu halten, dass sie von den Gewinnen (Sonnenenergie, inneres Waermeaufkommen u.a.) gedeckt werden koennen. Damit wird der Waermeschutz des Gebaeudes vielleicht bis an die Grenzen getrieben und es entstehen neue Anforderungen an das Energiemanagement und die Qualitaet der technischen Gebaeudeausruestung.

    This final report for the Swiss Federal Office of Energy (SFOE) presents the results of a project that involves the building of a joint biogas plant serving 60 farmers and industrial companies with an annual processing capacity of 45,000 tons. The plant is to produce biogas to be fed into the gas mains and will not only reduce nutrient loading in a region with an extensive livestock industry but also reduce carbon dioxide emissions by using the gas as a motor fuel. The importance of the project with respect to both the environment and energy policy-making is discussed and the costs involved are examined. Details are presented on the technology used and on the material flows involved. Figures are quoted on energy production. The various biogenic substrates used, such as food wastes, waste oils, cereal wastes and used mushroom substrates, are discussed, as is the use of the solid and liquid outputs of the digester in farming activities.

  6. High-power stirling-type pulse tube cooler for power engineering applications of high temperature superconductivity; Hochleistungspulsrohrkuehler vom Stirling-Typ fuer energietechnische Anwendungen der Hochtemperatursupraleitung

    For the cooling of high temperature superconducting 4 MVA machines (motors or generators), a single-stage Stirling-type pulse-tube cryocooler was built. The cooling power, which the cryocooler was aimed for, is 80 - 100 W at 30 K with an electrical input power of 10 kW (8 kW pV-power). The advantages of this cooler type compared to traditional cooling concepts are an increased reliability and long maintenance intervals. While single-stage Stirling-type pulse-tube cryocoolers for the temperature range of liquid nitrogen (77 K) are already commercially available, there exist currently no commercial systems for the temperature range near 30 K, which is the important range for applications of high-temperature superconductivity. The experimental setup consisted of a 10 kW linear compressor, type 2S297W, from CFIC Inc. which was used as the pressure wave generator. The compressor was operated by a Micromaster 440 frequency inverter from Siemens, which was controlled by a custom-made computer program. The cold head was made in inline configuration, in order to avoid deflection losses. During the first cool-downs tests a temperature inhomogeneity occurred in the regenerator at low temperature and high pV-power, which was attributed to a constant mass flow (circular dc-flow) within the regenerator. This firstly observed dc-flow, generates a net energy flow from the hot end to the cold end of the regenerator, which reduces the cooling capacity considerably and hence the minimum attainable temperature is severely increased. For the design and optimization of the cold-head, a cryocooler model was initially created using the commercial simulation software Sage, which did not include the regenerator inhomogeneity seen in the experiment. For the modeling of the observed streaming inhomogeneity caused by the dc-flow, the regenerator was replaced by two identical parallel regenerators with variable transverse thermal coupling. In the inhomogeneous case (without dc-flow) the extended model showed the same results as the original model. When choosing a regenerator with non-linear temperature profile as initial condition, a dc-flow also occurred in the extended model. With the help of this model, the conditions for the appearance of this new loss mechanism can be analyzed. It turned out that the transverse heat conductance in the regenerator matrix as well as the mass flow (pV-power) are important parameters. The insights from the numerical model were used for the development of a new analytical model, which is able to reproduce the observed dc-flow in the experiment quantitatively. After the occurrence of the regenerator streaming in the experiment, it was first tried to uniform the flow at the aftercooler by using appropriate bezels. As this did not shown the desired effect, a sandwich structured regenerator made of good and bad thermal conducting screens (stainless steel-, copper-, and brass mesh) was used in order to increase the transverse heat conduction. By these measures the azimuthal temperature gradient was considerably decreased, resulting in a reduction of the streaming flow. By optimization of the sandwich structure, the initial base temperature of the cold head of 65 K was reduced to 34 K. The cooling capacity at 40 K was 20 W with a pV-power of 6 kW. This represents a Carnot efficiency with respect to the pV-power of 1.5%. Due to the formation of a regenerator streaming at high input power, a base temperature below 30 K could not be achieved. Since the losses by the regenerator streaming flow at higher temperatures are lower, the cold head was adjusted by shortening the regenerator to operate at 80 K. The realized cooling capacity in this case was 350 W with a pV-power of 8.4 kW, corresponding to 11% of the Carnot efficiency with respect to the pV-power.

    Straw and gas can be converted only in a few biogas plants in Germany. One of these is the Kolbermoor plant as it works by the Rottal process. This biological and technical concept is based on a separation of hydrolysis and methanation. This means that horse manure can be used as a cheap energy source, and the dried fermentation residue can be used for heating.

    Full Text Available The »juridification« of covert investigations in the transition from the ius commune inquisition process to the reformed criminal justice process of the 19th century, understood as a material (i. e. law creating normative distinction between true or wrongful circumstances, is a complex phenomenon. This paper traces the introduction of covert investigations into the law of criminal procedure. It takes its starting point in the uncodified, but nevertheless legally sophisticated search and seizure of letters or the use of informers in the ius commune process. Influences of the French Revolution on the development of law, the 19th century’s early individual legislation, but mainly the tumultuous times before the Revolution of 1848 and the great surge of single procedural codes in the mid 19th century are the subject-matter of this analysis. This research has unearthed some surprising facts: Juridification affects various measures in quite different ways. At the same time, it is shaped by subjects which are hardly comparable with one another (monarchs, parliaments etc., and it is associated with the production of the criminal process as a subject that manifests itself particularly in the redefining of the pre-trial phase.

Diese Fähigkeit war den Zyklopen fremd. Sie ’sahen‘ nur mit einem Auge. Monokularsehen erzeugt im Hirn zwar auch ‚wirklichkeitsnahe‘ Bilder, ihnen fehlt es jedoch an Räumlichkeit, an Komplexität. Das führt zu schmerzhaften Kollisionen mit ‚der Wirklichkeit‘. Dieses Bild greift Brigitte Dehne im Untertitel ihres Buches Gender im Geschichtsunterricht auf, das die innerhalb der Geschichtswissenschaft längst außerordentlich elaboriert diskutierte Kategorie „Gender“ als Handlungskonzept für den Geschichtsunterricht erschließt.The Cyclops, those undefeatable giants of Greek mythology, had their eye in the middle of their forehead—in the exact place of the third eye, to which other world views have attributed intuitive or wholeness in sight. This ability was foreign to the Cyclops. They ’saw’ only with one eye. Monocular seeing admittedly also creates ‘realistic’ images in the brain, but missing from these images is three-dimensionality and complexity. This leads to painful collisions with ‘reality.’ Brigitte Dehne utilizes this image in the subtitle of her book Gender in the History Lesson (Gender in Geschichtsunterricht, which makes “gender,” a category that has long been an exceptional and elaborately discussed concept in historical studies, accessible as a method of approach in the history classroom.

    The responsibility of human beings for the creation in its ethical dimension can only be made clear against a scientific-technical and economic background since human beings have to act in their natural surroundings in view of the world that is becoming more and more complex and at the same time closer through technology, and in view of the fast growing world population and the possible hazards of the viability of the biotope Earth. After World War I, Max Weber differentiated in his famous essay 'Politics as a Vocation' between the ethics of believe and the ethics of responsibility. It can be discussed whether both streams are according to the opinion of Max Weber 'in abysmal contrast'. (orig.) [German] In dem Wort 'Verantwortung' steckt der Wortstamm 'antworten' -, und zwar zunaechst dem eigenen Gewissen zu antworten. Das aber basiert auf sittlichem Bewusstsein, aber auch auf Wissen und Urteilsfaehigkeit und damit auf der Moeglichkeit, zu werten. Werten zu koennen, das erfordert aber, den Wirkungszusammenhang des Geschehens und die Rolle des Menschen in ihm zu verstehen. Die Verantwortung des Menschen fuer die Schoepfung ist nur vor einem naturwissenschaftlich-technischen und einem volkswirtschaftlichen Hintergrund in ihrem ethischen Bezug zu verdeutlichen. (orig.)

    The general principles of medical surveillance for workers exposed to ionizing radiation were defined in the Euratom Basic Standards in 1959. These principles, which are in accordance with the early IGRP publications, have been adopted by the national authorities and implemented without difficulty. However, because of the forthcoming publication of the revised Basic Standards- in accordance with recent IGRP recommendations, the Commission decided to organize a meeting of doctors responsible for the medical surveillance of workers exposed to ionizing radiation in order to disseminate as widely as possible the results of experience gained in the field of radiological protection and to pinpoint the practical difficulties which might arise when the principles were applied. The Commission also considered it important to inform doctors specializing in radiological protection about the principles to be followed by those responsible for the health protection of workers exposed to non-ionizing radiation, particularly microwaves and Laser beams.

    Migration measurements of acetabular components using a special computer aided method (EBRA = abbrevation for the German term ``Ein-Bild-Roentgenanalyse``) were performed to evaluate early results of the implants and predict aseptic loosening. Methods: Standard ap-radiographs of the pelvis were marked, specific points were digitised. Simulating the spatial situation the programme computes lengitudinal and vertical migration of the cup. 74 acetabular components in 71 patients could be studied by migration measurements. Results: 14 patients showed migration of more than 1 mm, which is the confidence limit of this method. Each of these patients showed diverse reasons for the migration, i.e. osteoporosis of the acetabular bone stock or problems concerning the surgical technique which means malposition of the cup or insufficient reaming of the bone. There were some patients with severe congenital dysplasia of the hip and in some cases the inclination angle of the cup was too great. Conclusion: The technique applied for measuring migration of acetabular components can be useful for evaluating early instability of the implant and can be helpful in detecting problems concerning the surgical technique.

    In the past, Al{sub x}Ga{sub 1-x}As single and multiple-junction solar cells have been manufactured and tested. Although the ternary Al{sub x}Ga{sub 1-x}As is one of the most studied semiconductor systems, the results have often lagged behind expectations. In the thesis presented here, for the first time, the deep understanding of the Al{sub x}Ga{sub 1-x}As material system resulting from material analysis was linked with its application in solar cells. As has been shown, many cell results can only be explained if the peculiarities of the material, in particular the formation of DX centers and the transition from direct to indirect semiconductor, are also included. From this purposeful consideration of the material in terms of its usefulness in the semiconductor device and the technological significance of individual properties, not only high-quality solar cells based on Al{sub x}Ga{sub 1-x}As were produced but also new insights into the material properties of (Al{sub y}Ga{sub 1-y}){sub 1-z}In{sub z}As and the information gain from photoluminescence measurements can be significantly increased.

In der hier vorgestellten Dissertation wurde zum ersten Mal das aus der Materialanalytik heraus entstandene, tiefe Verstaendnis ueber das AlxGa1-xAs Materialsystem mit seiner Anwendung in Solarzellen verknuepft. Wie sich gezeigt hat, werden viele Zellergebnisse erst erklaerbar, wenn auch die Besonderheiten des Materials, insbesondere die Bildung von DX-Zentren und der Uebergang vom direkten zum indirekten Halbleiter, mit einbezogen werden.

    We present a 61-year-old male patient with progressive dementia. A brain SPECT with Tc-99m-bicisate was performed for confirmation of clinically suspected Alzheimer-dementia. At the time of the SPECT-investigation marked apraxia and aphasia besides severe dementia were present. Electrophysiological as well as anatomical neuroimaging findings showed non-diagnostic alterations. SPECT revealed distinct perfusion defects, which made Alzheimer Dementia unlikely. The further course of the patient was determined by rapidly progressive deterioration with development of akinetic mutism. Thereafter, increased levels of neuron-specific enolase as well as 14-3-3 proteins were found in the cerebro-spinal fluid (CSF). The patient finally died with signs of cerebral decortication. Due to the clinical course and the CSF-findings the patient's final diagnosis was Creutzfeld-Jakob-disease, nevertheless no autopsy was performed. The presented case report underscores the clinical utility of perfusion brain SPECT in the differential diagnosis of dementias. (orig.)

    Radiological imaging only reflects the anatomy and its pathological abnormalities. Therefore, the radiologist should be able to recognize the basic features of the pathological anatomy of bone tumors. This can only be learned working closely with a pathologist who is experienced in this field. On the other hand, the pathologist needs from the radiologist their diagnostic assessment with information on size, location, aggressiveness and the existence of a bone tumor's matrix, of the whole lesion, because he usually only receives a small part for examination in the form of a biopsy. In this article, the features and fundamentals (standards) of radiological-pathological cooperation as the mainstay for a precise diagnosis in bone tumors are outlined. The radiological appearance and the histopathological features behind it are presented for Ewing's sarcoma, fibrogenic tumors, giant cell tumor, and hemangioma of the bone. (orig.) [German] Radiologische Bilder spiegeln nichts anderes als die Anatomie und ihre pathologischen Abweichungen wider. Deshalb sollte der Radiologe die Grundzuege der pathologischen Anatomie auch von Knochentumoren kennen. Das kann er nur durch eine enge Zusammenarbeit mit einem auf diesem Gebiet erfahrenen Pathologen erlernen. Andererseits braucht der Pathologe vom Radiologen dessen diagnostische Einschaetzung mit Informationen ueber die Groesse, Lage, Aggressivitaet und das Vorhandensein einer Matrix eines Knochentumors und zwar von der gesamten Laesion, denn er bekommt inform einer Biopsie i. d. R. nur einen mehr oder weniger kleinen Teil zur Untersuchung. In diesem Beitrag werden die Grundzuege und Standards der radiologisch-pathologischen Zusammenarbeit aufgezeigt, auf denen eine praezise Diagnosestellung beruht.

    The key to the survival of future generations is the availability of energy. This is the first publication ever to provide a current and comprehensive overview on current issues of German energy policy. The author concludes that the efficient handling of energy is necessary and correct, but this will not be enough by far to secure future energy supply. We will have to abandon the concept that these problems may be solved by wind power or solar power, as the book shows that these energy sources are not successful. Until advanced efficient technologies will arrive commercially on market, fossil fuels will be available in sufficient supply, but current energy policy strategies do not take account of this fact. The following issue derived from ''Energy - what everyone should know about it'' is enlarged by the chapter electromobility. (orig./GL) [German] Mit dieser Schrift liegt eine in wesentlichen Punkten erweiterte Neubearbeitung des Sachbuches Energie was jeder darueber wissen muss vor. Dr. Gustav Krueger gibt damit einen umfassenden Ueberblick ueber die aktuellen Fragen der Energiepolitik. Neu hinzugefuegt wurde das Kapitel Elektromobilitaet.Das Fazit des Autors: Sparsamer Umgang mit Energie ist notwendig und richtig, genuegt jedoch zur Sicherung des zukuenftigen Energiebedarfs bei weitem nicht.Krueger erlaeutert ausfuehrlich die Gruende, aus denen man sich schnellstmoeglich von der Vorstellung verabschieden sollte, energiepolitische Probleme seien schon heute mit Wind- und Solarkraft zu loesen. Es gibt zwar vielversprechende Ansaetze vom Aufwindkraftwerk bis hin zu Energie aus Algen und Wellenkraftwerken. Doch bis zur Marktreife neuer und effizienter Technologien muss auf fossile Energietraeger und Kernkraft zurueckgegriffen werden. (orig.)

    In the world's biggest research project, the sick building syndrome was investigated in Germany between 1995 and 1999. In all, 8 air-conditioned buildings and 6 non-air-conditioned buildings, 40 space HVAC systems and 1497 places of work were analyzed, and 4,500 persons were asked to provide data. For the first time ever, measured physical, biological and chemical data were compared with the subjective data provided by the inquiry forms. It was found that the concentrations and hygienic status of air conditioning systems do have an effect on subjective comfort. Buildings with well-designed and well-serviced space HVAC systems had better results than buildings without air conditioning systems. However, it is the psychosocial environment and the job description of building inhabitants that decide their response in terms of sick building syndrome. Factors like gender, job satisfaction, job specifications and educational level are more important than space HVAC systems. [German] Im Rahmen eines der weltweit groessten Forschungsprojekte zum Thema 'Sick Building Syndrome' wurden in Deutschland zwischen 1995 und 1999 umfangreiche Untersuchungen durchgefuehrt mit dem Ziel, die Ursachen und Folgen von Befindlichkeitsstoerungen in Buerogebaeuden zu ermitteln. Insgesamt wurden 8 klimatisierte und 6 nicht klimatisierte Gebaeude, 40 raumlufttechnische Anlagen und 1497 Arbeitsplaetze untersucht sowie ueber 4.500 Personen befragt. Die Ergebnisse erlauben zum ersten Mal einen direkten Vergleich der gemessenen physikalischen, biologischen und chemischen Werte mit den subjektiven Angaben (Fragebogendaten) an klimatisierten und nicht klimatisierten Arbeitsplaetzen. Die Auswertung zeigt, dass die Konzentration der Anlagen und deren hygienischer Wartungszustand einen Einfluss auf die Befindlichkeit der Mitarbeiter haben. Gebaeude mit gut geplanten und gewarteten RLT-Anlagen schneiden in der Bewertung sogar besser ab als nicht klimatisierte Gebaeude. Die groessten

    Many features from the background for an intensified application of fracture mechanics concepts in many industries world-wide. These include requirements for a permanent increase of the level of performance of technical components and structures by the introduction of new materials, joining technologies and design principles, the problem of ageing components and life extension, an increased emphasis on non-destructive in-service inspection combined with improved NDT techniques, and also a number of failure events caused by fatigue and fracture The aim of the present paper is to give a brief state-of-the-art review on how fracture mechanics is applied in different industrial branches today. This is based on standards and guidelines in the aerospace industry, in the nuclear and fossil power generation, in the chemical and petrochemical and the pipeline industry, in civil engineering, offshore technique and other fields. Based on the review an outlook is given on a future development that would be reasonable and desirable from the point of view of a basically unified philosophy of fracture mechanics application.

    The first two pilot plants for solar district heating with seasonal thermal energy storage were put in operation in October 1996. Both projects were initiated by the Institute for Thermodynamics and Thermal Energy Technology (ITW) of the University of Stuttgart that also provided scientific support up to the present. This report presents the results of the first two years of operation of both plants. Both solar plants have been operated without any major problems. The solar energy yield in the first year of operation has only been reduced by the unsatisfactory operation of the heating grid. The most important step towards optimising the plants is the adjustment of the internal heating systems and thus the reduction of the heating temperatures which are currently too high. Based on subject pre-conditions the results projected for the first pilot plants for solar district heating and long-term thermal energy storage will be reached in the following years of operation. (orig.) [Deutsch] Im Oktober 1996 gingen die ersten beiden Pilotanlagen zur solaren Nahwaermeversorgung mit saisonaler Waermespeicherung in Betrieb. Beide Projekte wurden vom Institut fuer Thermodynamik und Waermetechnik (ITW), Universitaet Stuttgart initiiert und ueber die gesamte bisherige Laufzeit wissenschaftlich begleitet. Die Ergebnisse des ersten Betriebsjahres der beiden Anlagen sind in diesem Bericht zusammengestellt. In beiden Faellen funktionieren die Solaranlagen ohne grosse Probleme. Die solaren Ertraege wurden im ersten Betriebsjahr noch durch die unzureichende Betriebsweise der Heiznetze gemindert. Wichtigster Ansatzpunkt fuer eine Optimierung der Anlagen ist die Einregulierung der hausinternen Heizungssysteme und damit die Absenkung der derzeit noch zu hohen Heiznetztemperaturen. Unter dieser Voraussetzung werden die vorausgesagten Ergebnisse fuer die ersten Pilotanlagen zur solaren Nahwaerme mit Langzeit-Waermespeicher in den naechsten Betriebsjahren erreicht werden.

    Although modern trucks have many electronic systems, an integrated electronic steering system is still lacking. A demonstration model of an integrated, fully electronic powertrain - the X-by-wire system - was presented by DaimlerChrysler AG at the IAA Nutzfahrzeuge in September 2000. Among other functions, the system will facilitate backing-up of trucks with trailers or road trains. [German] Zahlreiche Systeme erleichtern LKW-Fahrern die Arbeit: z.B. Bremskraftverstaerker, Lenkkraftservos und elektronisch geschaltete Getriebe. Das grundsaetzliche Konzept der Fahrzeuglenkung bleibt jedoch erhalten: Der Fahrer greift auf einzelne Aggregate zu wie beispielsweise Motor, Bremse, Getriebe und Lenkung. Eine rein elektronische Steuerung ohne mechanische Verbindung, die eine gemeinsame Schnittstelle mehrerer oder aller Aggregate bereitstellen koennte, befindet sich gerade in der Entwicklung. Ein Demonstrationsmodell eines integrierten rein elektronisch ansteuerbaren Antriebsstrangs wurde von DaimlerChrysler AG auf der IAA Nutzfahrzeuge im September 2000 vorgestellt. Die X-by-wire Technologie eroeffnet voellig neue Moeglichkeiten fuer echte Fahrerassistenzsysteme, die nicht nur Kraftverstaerker sind, sondern auch Informationsverarbeitung betreiben. Ein Beispiel fuer ein solches System ist ein Rueckwaertsrangierassistent, der dem Fahrer bei der Rueckwaertsfahrt mit Auflieger oder Gliederzug die schwierige Aufgabe abnimmt, das ungewollte Einknicken des Zuges zu verhindern. Dazu ist es notwendig, dass der Lenkwinkel der Zugmaschine von einem Regler vorgegeben wird, der neben der vom Fahrer gewuenschten Kruemmung auch die Knickwinkel des Zuges mit einrechnet. Der Fahrer greift damit nicht mehr auf den Lenkwinkel zu, sondern gibt dem Regler einen Sollwert fuer die gewuenschte stabiliserte Bahnkruemmung des Zuges vor. Jeder, der schon einmal selber mit einem Anhaenger rueckwaerts rangiert hat oder zumindest ein solches Manoever beobachtet hat, weiss unmittelbar wieviel

    New information systems and additional vehicle functions require the driver to engage in an interaction with the car which may distract him from driving. Following the model of multiple resources (e.g., [9]) this distraction will be strong if the visual channel is used for the information input and if a motor reaction is necessary. To avoid this interference, a driver-vehicle-interaction could use the acoustic channel and verbal reactions. As speech recognition and speech output is still problematic in the car, driver assistance systems can be introduced to assist the driver and free resources which can be used for the interaction. The paper presented here tests these two approaches in a driving simulation. Although both approaches show avoid interference to some extent, negative effects can also be demonstrated. Thus, these strategies should be well designed and tested. (orig.) [German] Informationssysteme im Fahrzeug und zusaetzliche Fahrzeugfunktionen fuehren dazu, dass der Fahrer vermehrt in eine Interaktion mit dem Fahrzeug eingebunden wird, die vom Fahren ablenken kann. Entsprechend einem Ressourcenmodell der menschlichen Aufmerksamkeit (z. B. [9]) ist diese Ablenkung dann besonders stark, wenn bei der Informationsaufnahme der visuelle Kanal genutzt wird und die Handlungsausfuehrung motorisch geschieht. Deshalb wird gefordert, die Fahrer-Fahrzeug-Interaktion ueber Sprachausgabe und Sprachkennung zu gestalten. Da dies nach wie vor technisch im Fahrzeug (Umgebungsbedingungen, Wortschatz) schwierig ist, sollen alternativ Fahrerassistenzsysteme die negativen Effekte kompensieren. Im vorliegenden Beitrag werden diese beiden Ansaetze geprueft. Zwar zeigen sich fuer beide Ansaetze Teilerfolge, aber eine unkritische Anwendung kann auch negative Effekte nach sich ziehen. (orig.)

    In force since 1990, the German Stromeinspeisungsgesetz (obliging electric utilities to purchase at mandatory prices electricity from renewable energy sources) still is an issue of debates about legal justification under German law and compatibility with legislation on the European Internal Market for elctricity. The contribution analyses the points of friction with the Treaty of Rome, in particular the European regulations governing subsidization of national industries or undertakings by their government, aspects of freedom of trade within the EU and restrictive trade practices law. The conclusion of the legal analysis is that the German act is compatible with the subsidy regulations of the EU, but calls for amendment to correct infringements of the principles of free trade and competition within the EU in the provisions excluding electricity from renewables generated in other EU Member States. (CB) [Deutsch] Es ist schon seit 1990 in Kraft, und das Stromeinspeisungsgesetz bietet nach wie vor Anlass zu Diskussionen, sowohl aus dem Blickwinkel des deutschen Rechts wie auch vom Standpunkt des EGV. Der Beitrag konzentriert sich auf die rechtlichen Reibungspunkte mit europaeischem Recht, konkret die Regelungen ueber erlaubte staatliche Beihilfen an nationale Unternehmen, deren Abgrenzung zu allgemein wirtschaftspolitischen Massnahmen eines Staates und Aspekte der Warenverkehrsfreiheit und des Wettbewerbs auf dem europaeischen Binnenmarkt. Das Ergebnis der rechtlichen Analyse des Beitrags sieht in der Subventionierung der Stromerzeugung aus erneuerbaren Energien eine politische Entscheidung, die mit EG-Interessen und EG-Recht vereinbar ist. Das Gesetz verstosse jedoch gegen die Warenverkehrsfreieheit auf dem Binnenmarkt in den Regelungen, wo es entsprechend erzeugten Strom aus anderen Mitgliedslaendern von der Subventionierung ausnimmt.

    The author discusses aspects of international harmonization of laws and regulations in this field and describes such activities at the European level and within the EU, and under WTO agreements. (orig./CB) [German] Zur Verwirklichung des Binnenmarktes fuer Lebensmittel kommen nach dem EG-Vertrag Massnahmen der Rechtsangleichung in Betracht (Art. 100a Abs. 1 EGV). Insoweit beruht die Freiheit des Lebensmittelverkehrs im Binnenmarkt auf der gemeinschaftsweiten Harmonisierung der nationalen lebensmittelrechtlichen Regelungen. Ausserhalb dieses harmonisierten Bereichs gewaehrleistet die unmittelbar im EG-Vertrag in Art. 30 verankerte Warenverkehrsfreiheit den freien Verkehr mit Lebensmitteln im gesamten Gebiet der Gemeinschaft. Insoweit folgt aus der Cassis de Dijon-Rechtsprechung des Gerichtshofes der Europaeischen Gemeinschaften (EuGH) das Prinzip der gegenseitigen Anerkennung: Lebensmittel, die in einem anderen Mitgliedstaat rechtmaessig hergestellt oder dort rechtmaessig in Verkehr gebracht worden sind, duerfen grundsaetzlich in jedem anderen Mitgliedsstaat vermarktet werden. Dabei stellt der Schutz der Verbraucher eine vom EuGH bereits in die Gewaehrleistung des freien Warenverkehrs in Art. 30 EGV hineingelesene ('immanente') Schranke dar. Daneben darf der freie Warenverkehr gemaess Art. 36 EGV ausdruecklich auch zum Schutz der menschlichen Gesundheit eingeschraenkt werden. In dem auf der Grundlage des Art. 100a Abs. 1 EGV harmonisierten Bereich des Warenverkehrs soll ein hohes Niveau des Gesundheits- und Verbraucherschutzes verwirklicht werden (vgl. Art. 100a Abs. 3 EGV). Art. 100a EGV wird auch die Kompetenzgrundlage fuer zwei sich ergaenzende EG-Richtlinien ueber die ionisierende Bestrahlung von Lebensmitteln sein, deren Entwuerfe gegenwaertig auf der Ebene der Europaeischen Gemeinschaft beraten werden.

    Aim: This work is engaged with the volume change of neck lymph node metastasis of malignant tumors in the head-neck region during radiotherapy. Patients and Method: In 54 patients with head and neck tumors, the volume of neck lymph nodes before and after radiation was measured. The volumetry was done with CT planimetry. The total dose was 66 Gy (2 Gy/d) telecobalt from 2 lateral opponated fields. The time of volume change could be defined with measuring of the half-time and the doubling-time by the help of Schwartz formula. Results: After 10 Gy the volume diminution was about 20% and half-time 24 to 26 days. Afterwards the time of volume diminution picked up speed and finally achieved 60 to 72%. Meanwhile the half-time decreased to the half value. The result was independent of the site of primary tumor, the patient`s sex and age. (orig.) [Deutsch] Ziel: Diese Arbeit beschaeftigt sich mit der Volumenveraenderung von Halslymphknotenmetastasen maligner Tumoren im Kopf-Hals-Bereich waehrend einer strahlentherapeutischen Behandlung. Patienten und Methode: Bei 54 Patienten mit Kopf-Hals-Tumoren wurde das Volumen der Halslymphknotenmetastasen vor und nach Strahlenbehandlung (bei sieben Patienten auch nach 10 Gy) bestimmt. Der Primaertumor war in allen Faellen ein Plattenepithelkarzinom. Zur Bestimmung des Volumens der Lymphknotenmetastasen bietet sich als genauestes bildgebendes Verfahren die CT-Planimetrie an. Jeder Patient wurde mit Telekobalt ueber zwei opponierende laterale Felder bis zu einer Gesamtdosis von 66 Gy (taegliche Einzeldosis 2 Gy) bestrahlt. Die Dynamik der durch die Bestrahlung hervorgerufenen Volumenveraenderung wurde mit Hilfe der Halbwerts- bzw. Verdoppelungszeit nach der Formel von Schwartz berechnet. Ergebnisse: Nach 10 Gy betrug die Volumenverkleinerung etwa 20%, die Halbwertszeit 24 bis 26 Tage. Danach beschleunigte sich die Volumenverkleinerung und erreichte zuletzt 60 bis 72%. Die Halbwertszeit verringerte sich auf etwa die Haelfte. Das Ausmass

    The heavy metal loading of flow from roofs depends, on the one hand, on the deposited load of dust and on the other hand, on the material used. The resulting solution process are especially prominent if the pH values are low and there is limitation of particulate material, together with a missing ability to buffer. For roads in town areas, the loading of the surface flows does not only depend on the traffic density. This applies most for particle loading regarding some elements. Driving behaviour, eg: Frequent starting and braking, is also important here. The background loading, flushing of unsolidified surfaces and other activities (eg: Intensive building work) also affect the loading of side streets. During the precipitation events examined, after about 6 mm of precipitation, the washing out of the layer of air near the ground was ended. After rain of 15 mm has fallen, the nearly complete flushing of the particulate load was found for two events. About 80% of heavy metal loading (for Cu only about 50%) of the catchment area is caused by emission from road traffic. Copper roofs emit about 40% of the CU load. The heavy metal load of flow from roofs is mainly contained in the liquid phase (except Pb, Fe), however the load from flow from roads in 90% bount to particles. Reduction of this heavy metal load could therefore occur via the AFS reduction. From the calculation carried out on the basis of known mean values, the city cleaning at Dresden at present removes about half of the total FE and Ni load and about 40% of the total Cu, Pb and Zn load of the catchment area.

Im ersten Erprobungsjahr ging es schwerpunktmaessig um die Induzierung der Calcitfaellung im Hypolimnion und die Untersuchung ihrer Wirksamkeit auf die P-Elimination unter Sauerstoffmangel. Waehrend der zwei ca. einmonatigen Betriebszyklen im Zeitraum vom 26.06.1996 bis 05.10.1996 wurden 140 t Ca(OH){sub 2} und 416 000 m{sup 3} Luft in das Hypolimnion des Carwitzer Beckens (Schmaler Luzin) eingebracht. Die pH-Werte im Hypolimnion wurden von 7,2 auf bis zu 9,1, ueber dem Sediment (2-3 cm) von 7,2 bis 8,2 und in den oberen Sedimentschichten von 7,4 auf bis zu 8,6 angehoben. Dadurch wurde das Kalk-Kohlensaeure-Gleichgewicht zum Carbonat hin verschoben, es kam zu Calcitfaellungen im Hypolimnion. Wie zu erwarten war, reichte die Betriebsdauer der Tiefenwasserbelueftung und die eingetragene Sauerstoffmenge nicht aus, um im gesamten Hypolimnion oxische Bedingungen herzustellen. Im unteren Bereich des Hypolimnions ergaben sich auch nach den Betriebszyklen anoxische Verhaeltnisse. Trotzdem kam es zu einer Phosphorabnahme. Ueber die kuenstlich ausgeloeste Calcitpraezipitation erfolgte eine Phosphor-Mitfaellung. Diese Phosphor-Mitfaellung wurde durch die Abnahme von geloestem reaktivem Phosphor und Gesamtphosphor sowohl im hypolimnischen Wasser als auch an der Sediment-Wasser-Kontaktzone belegt. Die Konzentration an geloestem reaktivem Phosphor ueber dem Sediment (2-3 cm) lag im Sommer 1996 mit 0,04 mgl{sup -1} um fast eine Zehnerpotenz niedriger als 1995 (0,31 mgl{sup -1}). (orig.)

It is already foreseeable that after 40 years a final repository will not be available. This means that the Castor casks and the interim storage halls will have to be operated at least for the 21st century without valid licensing.

    A group of 135 patients who suffered from Hodgkin's disease with long-term remission following radiotherapy was investigated. By restricting the investigations to the patient group with long-term remission and correlative examinations, it was tried to differentiate between exclusive or principal delayed radiation effects and delayed effects due to other factors. The study reports about the most significant results obtained in the fields of catamnesis, laboratory diagnostics, hematology, pulmology, cardiology, thyroid function tests, neurology, andrology and dermatology. Due to the numerous detectable delayed effects the group of patients with long-term remission receives a special status. Although those effects are in no proportion to the deletary risks of an untreated Hodgkin's disease and though they are consequently tolerable in the present state of the therapeutic development, they must initiate the completion of the therapeutic concept including performance of radiotherapy and aftercare, because only then the risk for the patient provoked by these effects, which ranges beyond the malignity of this disease can be reduced or prevented.

    For the present study, ten publications on the effect of UV radiation were analyzed. In vitro tests were carried out with one biological substance and seven different human or animal organs and biocytocultures. In vivo, three bacterial strains were irradiated and four irradiation experiments were carried out on mice. As to the effect of microwave radiation, eleven publications were analyzed. In vitro tests were carried out with one biological substance and three animal organs. In vivo, one bacterial strain was irradiated and eight irradiation experiments were carried out on different types of animals. The study's aim was to obtain a survey on biochemical changes of the organisms. Phenomenological changes were given only when the corresponding articles contained further investigation results. Behavioral changes were not taken into account. The results published by the authors of the original papers were compiled in a kind of dictionary. All relevant data are listed in a defined order.

    On 29 March 2017 the official letter from the United Kingdom to the President of the EU Council was presented to inform the European Council of its intention to withdraw from the European Union (EU). The period of 2 years in Article 50 of the EU Treaty provided for the exit negotiations has thus begun to run. In the letter to the President of the Council, the UK Government expressly declares its intention to withdraw from the EU and from the Euratom Treaty (EAV). Thus the controversy about the conjunction of the withdrawal from the EU and Euratom has become obsolete.

    The article reviews the development of emissions reduction in gasoline and diesel engines. Along with the historical developments and the factors driving them, it describes the most important characteristics and Mercedes-Benz's most important requirements for feasible post-treatment of exhaust gases. Adoption of the three-way catalytic converter has made the gasoline engine into a clean powerplant which easily meets even the strictest emission standards anywhere in the world. The next development goals for the gasoline engine are described as keeping emissions low while increasing fuel economy. One of the key technologies for achieving this is the NO{sub x} storage catalytic converter. In diesels, adoption of the diesel particle filter means that the conflict between particle reduction and nitrogen oxide reduction is receding into the background. But two new conflicts are emerging with the tightening of nitrous oxide limits and engine redesign measures to reduce NO{sub x}: hydrocarbons versus nitrogen oxide, and consumption versus nitrogen oxide. In addition to good drivability, the economy of the diesel engine is an important reason for its market success. Thus it is important for Mercedes- Benz to choose a NO{sub x} post-treatment that incurs the fewest possible consumption disadvantages and yet has the highest possible efficiency, so that engine-design solutions for reducing NO{sub x} can be restricted to measures that are consumption-neutral. Both the NO{sub x} storage catalytic converter and the SCR (Selective Catalytic Reduction) system will be described. The system that best meets overall requirements is the SCR-urea process. (orig.)

  5. Smoothness of running of large turbosets with particular regard to the coupling of rotor and foundation via slide bearings. Laufstabilitaet von grossen Turbosaetzen unter besonderer Beruecksichtigung der Kopplung von Rotor und Fundament ueber die Gleitlager

    1989-01-01

    Turboset operation is still faced with the unresolved problem of self-induced vibrations resulting from the hydrodynamic forces in the sliding bearings. In addition, more elastic supporting structures will result in a coupling of the vibration patterns of the rotor and foundations. These coupling mechanisms are investigated by the author. The stability calculation is carried out as follows: The equations of motion of the coupled overall system are established by a finite element method; the large number of degrees of freedom is condensed modally, and the specific eigenvalue problem is solved using the HQR algorithm. An iterative procedure, which is made necessary by the formulation of structural damping as viscous damping, determines the stability limit as the first 'zero run' of the real part of a complex eigenvalue. Eigenvalue tracking is possible if necessary. The application of the method to a medium-sized turboset and some parameter variations show that the stability limit will be changed significantly if the foundation is considered, depending on the degree of damping and the type of slide bearing. A realistic stability calculation should therefore be based on the coupled rotor/slide bearing/foundation model. (orig.) With 53 figs., 7 tabs.

    At the latest since Tschernobyl the use of radiation sources and ionizing radiation is due to missing knowledge of the public not affected by popularity but rather by fear. But the question is, whether it would be necessary on the part of the radiation users, not to conceal or mythologise the use, but to emphasize on educational advertising. (orig.)

  7. Investigations of the microstructural stability of wrought Ni-(Fe)-based syperalloys for steam turbine rotor application beyond 700 C; Untersuchungen der Strukturstabilitaet von Ni-(Fe)-Basislegierungen fuer Rotorwellen in Dampfturbinen mit Arbeitstemperaturen ueber 700 C

    There is a continuous trend to improve the efficiency of modern power plants with steam turbine require operating steam temperature from 700 to 720 C. For substantial parts like turbine rotors and discs this means increased requirements on the high temperature resistance, which can not longer be fulfilled by the presently used steel. As new materials for the components, which are thermo-mechanically loaded, only Ni-based superalloys are suitable for their fabrication, structure stability and thermo-mechanical characteristics. With view on creep and creep crack growth resistance as suitable candidates in the context a DFG research project wrought Ni-based superalloy Waspaloy and Ni-Fe-based alloy Inconel 706 were selected, which exhibited different hardening mechanisms. Waspaloy is a {gamma}'-hardened material with small portion of carbides on the grain boundaries. Inconel 706 is a particle hardened alloy with a very complex microstructure, it consists of {gamma}', {gamma}{sup ''}-particle, {eta}-phase und carbides. Concerning to their castability, forgeability, creep and creep crack growth and microstructural stability these candidate materials have been investigated and modelled. The knowledge about their long time stability of the microstructure, castability, forgeability and mechanical properties leads to the two new modification (Waspaloy{yields}DT750 and Inconel 706{yields}DT706). The modification of the Waspaloy to DT 750 served better castability (elimination of the Freckle formation). An improvement of the long-term stability of the microstructure was not necessary, by a changed heat treatment was reached a homogeneous, monomodale {gamma}'-particle distribution. The modification of Inconel 706 to DT 706 served to stabilize the {gamma}'-phase and to reduce of the {gamma}{sup ''} phase without suppressing the cellular {eta}-phase colonies on the grain boundaries. This work presents the test results for the structural long-term stability of the mentioned materials and their modifications. In this paper influences of heat treatments and thermal exposure on the microstructure and consequences for the mechanical behaviour will be discussed. (orig.)

    Most isotopes in the natural environment are stable but there are radioactive isotopes. Premordial radionuclides are nuclides that exist since the development of the earth crust. Cosmogenic radionuclides are generated due to cosmic radiation (protons, electrons, ionized atoms) - for instance C-14. Radiogenic nuclides are daughter products of radioactive nuclei. Anthropogenic radionuclides are generated due to human activities. Deviations from a ''normal'' isotope distribution are used for environmental impact analysis and forensic purposes. The human provenance project was stopped.

    Electricity exchange trading in Germany has existed since the year 2000. Since this time, the Leipzig electricity exchange, a reference market for off-exchange electricity trading, has operated in an environment marked by both criticism and acceptance. Taking this field of controversy as a point of departure the present empirical study in market sociology undertakes to investigate the organisation and latent functions of electricity exchange trading. The ensuing analysis provides answers to questions as to how prices are formed on the electricity exchange and what officially incommunicable functions are served by price formation on exchanges.

    Adventure is the opposite of conventional teaching. Adventure is the moment when experience alone is not enough. Sometimes, courageous people challenge the nature of things, helping us to get new insights and achieve a new viewpoint. The experience-oriented ''work in progress'' university is an adventure of this kind. The book looks into the Tesla laboratory and the Wardenclyffe Tower, both of which could not be completed for financial reasons, and addresses them from today's state of technology. The conceptional section is based on the ''Tesla doctrine'' which comprises fundamental philosophical statements on civilisatory progress. The book presents the results of the investigation. The 16 architectural projects presented here were developed live on the online platform. Second Life, ORTLOS Sim. (orig.)

    The development of wholesale electricity prices showed in recent years a very fluctuating course. The starting point for ensuring competitive compliant electricity prices have uniform rules that establish effective competition in the overall wholesale electricity, ensure greater transparency in the market and prohibit market abuse influence exercised on the wholesale price. The REMIT regulation creates a first union-law rules to this standardized specifications. The volume first examines the transparency, competitiveness, and supervisory structures in the wholesale electricity before legislating a regulation. It is clear, as the transparency and supervisory structures should be designed from the wholesale electricity ideally. On this basis, the work is dealing with the REMIT regulation. The author works out to market participants relevant notification and publication requirements, the follow-up demands on the company as well as the now existing prohibitions on market abuse and the related penalty catalog and analyze the supervisory structures newly created in the wholesale electricity. Here, the work also identified the weaknesses of the regulation and shows suitable solution approaches. [German] Die Entwicklung der Stromgrosshandelspreise zeigte in den letzten Jahren einen sehr schwankenden Verlauf. Ausgangspunkt fuer die Gewaehrleistung wettbewerbskonformer Strompreise sind einheitliche Bestimmungen, die im gesamten Stromgrosshandel einen funktionierenden Wettbewerb etablieren, fuer mehr Transparenz am Markt sorgen und marktmissbraeuchliche Einflussnahmen auf den Grosshandelspreis verbieten. Die REMIT-Verordnung schafft als erstes unionsrechtliches Regelwerk hierzu einheitliche Vorgaben. Der Band untersucht zunaechst die Transparenz-, Wettbewerbs-, und Aufsichtsstrukturen im Stromgrosshandel vor Erlass der Verordnung. Dabei wird deutlich, wie die Transparenz- und Aufsichtsstrukturen im Stromgrosshandel idealerweise ausgestaltet sein sollten. Auf dieser Grundlage setzt sich das Werk mit der REMIT-Verordnung auseinander. Dabei arbeitet die Verfasserin die fuer die Marktteilnehmer relevanten Mitteilungs- und Veroeffentlichungspflichten, die daran anknuepfenden Anforderungen an die Unternehmen sowie die nunmehr geltenden Verbote zum Marktmissbrauch und dem damit verbundenen Sanktionskatalog heraus und analysiert die neu geschaffenen Aufsichtsstrukturen im Stromgrosshandel. Dabei identifiziert das Werk auch die Schwaechen der Verordnung und zeigt hierfuer geeignete Loesungsansaetze auf.

    Quantitative analyses of secondary phenols, free amino acids, and of the enzyme activities arginase and asparaginase were carried out on spruce needles from six different forest sites in North-Rhine Westphalia. In addition, the effects of ozone on spruce aged seven to eight years were investigated. The aim of this was to find out whether there is a correlation between the phenol and amino acid metabolism and the damage rate in older spruce (31 to 60 years) and in younger spruce exposed to ozone. No correlation could be established with a single exception: In one site, the free amino acid pattern showed a 10-fold increase of arginine and an accumulation of ornithine and lysine. This indicates a disturbed nitrogen metabolism, in particular a stimulation of the urea cycle, which may be caused by anthropogenic over fertilizing with nitrogen. The findings for the spruce exposed to ozone indicate a more complex effect on the needle metabolism, which affects both the phenol metabolism (strong decrease of the catechine concentration) and the amino acid metabolism (increase of the alanine concentration). This may be caused by damaged membranes (i.e. higher permeability accompanied by sensitive changes in the metabolic compartmenting) or by a potential increase of transaminase activities. (orig./MG).

    The current state of knowledge of nuclear and elementary-particle physics has a checkered history, often characterized by shocking new concept formations, which also opens up to the present day students of physics only with difficulty. This book uses those controversial yet educational development in order to enable learners to improve access to the new concepts. It helps to understand how the physical picture of the smallest particles is today, and why it is so and not otherwise originated: Beginning in the detection of the atoms up to the current standard model of elementary-particle physics and the Higgs boson. So readers gain an impression of that great field, which is originated in the constant interplay between established theoretical models, confirmatory or contradictory findings, sometimes controversial new concept formations, and improved experiments - a process, that surely continues in the future. Guideline of the presentation is a comprehensible also in detail as possible reasoning argumentation. Students of physics before their B.Sc. degree will thus be able to acquire knowledge of the subatomic physics relating to general knowledge in their field. Also for physics teachers at schools or colleges, this new representation should be interesting. The second edition has been updated to the newest state of knowledge, in particular first results of the LHC have been incorporated.

    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.

    4 groups of rats of the Wistar-strain were subjected to ..gamma..-irradiation on the 16th day of gestation. 5 rats received 0,6 Gy low dose rate irradiation, 5 animals received 0,9 Gy low dose and 6 high dose irradiation, 3 females were shamirradiated. The male offspring of these 3 irradiation groups and 1 control group were tested for locomotor coordination on parallel bars and in a water maze. The female offspring were used in an operant conditioning test. The locomotor test showed slight impairment of locomotor coordination in those animals irradiated with 0,9 Gy high dose rate. Swimming ability was significantly impaired by irradiation with 0,9 Gy high dose rate. Performance in the operant conditioning task was improved by irradiation with 0,9 Gy both low and high dose rate. The 0,9 Gy high dose rate group learned faster than all the other groups. For the dose of 0,9 Gy a significant dose rate effect could be observed. For the dose of 0,6 Gy a similar tendency was observed, differences between 0,6 Gy high and low dose rate and controls not being significant.

    The energy revolution leads not only to build more wind turbines and the much-discussed circuit line from northern to southern Germany. Instead, the now old energy form of nuclear power needs to be handled. The disposal is one of the biggest unsolved issues of our time. In the conflict between energy and environment policies, the radioactive contamination of nuclear energy must be disposed of. The book is a highly topical compendium of legal and political aspects, which are not sufficiently taken into account because of their specialty in the public discourse. Based on the case study Konrad almost all legal and political priorities are treated very understandable.

    The ''EMF-Portal'' is an Internet-based information platform in the research area of non-ionizing radiation effects. It is supplied by a variety of linked information sources and it provides scientific knowledge based on the results of at present approx. 7.700 (mainly peer-reviewed) publications related to bioelectromagnetic interaction. Different help tools support the interested user in both finding and interpreting relevant data. The EMF-Portal is multi-lingual: English and German are currently supported, other languages can be added. It is the aim of the portal to enable all users, regardless of their education or occupation, to ask complex questions about EMF and their effects and to receive specific and comprehensive answers. Assisted by an interdisciplinary glossary and a database of everyday's exposure sources, as well as an in-depth literature database, the user obtains a dynamically generated answer based on the results of all related publication data. The answer may consist of either a list of corresponding literature references or of different types of statistics e.g. regarding investigated endpoints. The Information System consists of two main components: The knowledge based literature database (a.k.a. WBLDB) and the EMF-Portal. The WBLDB contains most of the relevant scientific literature published so far. In addition to the publication data, the descriptors (exposure, methods, results etc.) of each study are extracted. With the help of this database the user has detailed insight into individual publications without having to read the full text, and he can produce statistical overviews over corresponding related studies as well as an objective comparison between different publications. The EMF-Portal which is the subject of this research project consists of the following modules: The interdisciplinary glossary comprehensively explains related biological, medical, epidemiological, technical or dosimetric terms. The database of everyday's exposure sources is a collection of important technical parameters of common EM fields. Finally, a so-called inference machine links the three databases to help the user in making a database query as well as to present the result set. Three different query options have been implemented into the inference machine to obtain a list of corresponding publications. The simple query is able to translate and ''understand'' the entered keywords with the help of the interdisciplinary glossary and the exposure database. The search engine determines synonyms, acronyms and words similar to the search term. When the user query concerns an exposure source, the field characteristics (e.g. frequency range) are also taken into account for the reply. This query option is targeted mainly towards occasional non-expert users. Query example: The user asks for blood cancer and mobile phones. The search engine looks for synonyms and acronyms of the medical term (result: leukemia, ALL etc.) and the most important exposure characteristics of the technical term (e.g. frequency range). Subsequently, a query collects all corresponding articles from the literature database. The detailed query represents an ordinary database query. The user is able to phrase conjunctions and disjunctions, looking for publication data and keywords. Precise information can be entered into the expert query. This option is the most powerful and flexible query tool, as the user can describe exactly what he wants to look for: exposure parameters (frequency range, modulation, SAR etc.) and medical/ biological data (exposed system, endpoints) can be narrowed down. All three queries initially return a list of publications that meet the entered criteria. These lists can be sorted and browsed; detailed data of every listed and extracted article can be accessed. Based on the publication information extensive statistical analyses can be generated automatically. Citizens, politicians, decision makers as well as experts can obtain scientifically founded answers to their individual questions utilizing the internet information system regarding the effects of electromagnetic fields on the organism. Here, the user is supported not only with his question but also with the interpretation of the data base results. Different search options allow asking questions also by using German key words which are translated automatically, supplemented by thematically similar words and finally searched in the (usually) English language publications. Initially, the answer of the information system consists of a list of found publications. Upon selection of one of these publications the regarding information is comprehensibly prepared in German and shown in detail. Based on the publication list already different statistics can be displayed; the structure of the information system allows the future implementation of additional statistics. Further help offers complete the coverage of the EMF portal: an introduction into the basics of electromagnetic fields and their effects, an interdisciplinary glossary of more than 1500 biological/medical terms as well as a data base covering the most important characteristics of more than 100 EMF exposure sources in the everyday life.

    Over 250 soil and root samples were collected from forest nurseries and regional research plots as well as from open-air and open-top chambers. The samples were examined for plant parasitic, mycophagous and microphagous nematode and for nematodes able to transmit plant viruses.

    The nuclear consequences of the earthquake disaster in Japan represent a profound change for the peaceful use of nuclear power, also in Germany. In the light of these events, the German Federal Government, together with the Prime Ministers of the Laender in which NPPs are operated had reviewed the safety of all German NPPs by the German Reactor Safety Commission in close collaboration with the competent nuclear regulatory authorities of the Laender and, through an Ethics Commission on ''Secure Energy Supply'', also started a dialogue among the German society on the risks involved in the use of nuclear power and on the possibility of an accelerated transition to the age of renewable energies. Taking into account the results of the Reactor Safety Commission and the Ethics Commission on ''Secure Energy Supply'' as well as the absolute priority of nuclear safety, the Federal Government decided to terminate the use of nuclear power at the earliest possible date. The amendments in the Atomic Energy Act that went into force in August 2011 induce the progressive abandonment of electricity generation by NPPs in Germany by the end of 2022 at the latest. Germany took an active part in the assessment of the robustness of the NPPs in Europe (EU stress test) under the leadership of the European Nuclear Safety Regulators Group (ENSREG). The results of these reviews show that the German plants partly have considerable safety margins and that additional precautionary measures have been taken in order to prevent (preventive measures) or limit (mitigative measures) the effects of the beyond-design-basis events considered in the reviews. Based on the results of the plant-specific reviews, the RSK has derived first recommendations for further examinations. Some plant-specific improvement measures are already in implementation or planned. The results of the EU stress test will be taken into account in future RSK recommendations. On behalf of the BMU, the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) prepared an Information Notice on the conclusions drawn from the Fukushima accident for German NPPs. The recommendations also include measures for a further improvement of the control of beyonddesign- basis events. The recommendations essentially concern the electrical energy supply, residual-heat removal, and accident management procedures. As regards emergency preparedness measures, the Federal Environment Ministry has initiated a working group of the Commission on Radiological Protection (in Germany abbreviated as SSK) that carries out a review of the German regulations for emergency preparedness on the basis of the experience feedback from the Fukushima accident. Corresponding changes and measures will be defined once the results are available.

    As part of a study dealing with the concentration of benzene, toluene, xylene, and ethylbenzene in the neigbourhood of fillings stations (indoor and outdoor air, benzene in the blood, t,t-muconous acid in urine), a total of about 70 volatile organic compounds were analysed in the `personal air` (personal sampler) of 13 persons living in the neighbourhood of the filling stations and 6 control persons during the summer of 1996. The mean concentrations of alkene and cycloalkene were below 3 {mu}g/m{sup 3}. The mean concentrations of benzene, m/p-xylene and toluene were 4.5 {mu}g/m{sup 3}, 6.8 {mu}g/m{sup 3}, and 34 {mu}g/m{sup 3}, respectively. The mean contamination of all other substances was below 3 {mu}g/m{sup 3}, halogenated hydrocarbons were below 1 {mu}g/m{sup 3}. The mean VOC-concentrations in the personal air of those persons living next to the filling stations and that seen in the control persons were not different. On the whole, the concentrations of total volatile organic substances were low, all the higher values could be explained by individual occupational or private activities (e.g. redecoration of the flat or smoking). Compared with the data of the `environmental survey` 1990/91, all substances revealed substantially lower mean values; we suggest that seasonal differences in the study time may be the main cause.

Die mittlere Belastung mit Alkanen und Cycloalkanen lag bei allen Einzelsubstanzen unter 3 {mu}g/m{sup 3}. Die durchschnittliche Konzentration an Benzol, m/p-Xylol und Toluol betrug 4,5 {mu}g/m{sup 3}, 6,8 {mu}g/m{sup 3} und 34 {mu}g/m{sup 3}. Alle uebrigen Aromaten wiesen eine mittlere Belastung von unter 3 {mu}g/m{sup 3} auf. Saemtliche halogenierten Kohlenwasserstoffe lagen im Mittel unter 1 {mu}g/m{sup 3}. Die mittlere Belastung der personenbezogenen Luft im Atembereich von Tankstellenanwohnern unterschied sich nicht von der Belastung einer kleinen Gruppe von Kontrollpersonen. Die Belastung war insgesamt gering, einzelne Maximalwerte konnten durch spezifische berufliche oder private Belastungen (z.B. Renovieren der Wohnung waehrend des Untersuchungszeitraums, Rauchen) erklaert werden. Im Vergleich mit den Ergebnissen des Umweltsurveys 1990/91 wurden bei allen Einzelsubstanzen deutlich niedrigere Mittelwerte bestimmt; jahreszeitliche Unterschiede waehrend der Probenahmephase sind hier die wahrscheinlich bedeutendste Ursache.

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

    In a two year research project the long-term storage of hydrogen as energy carrier has been assessed in detail for large renewable electricity quantities in underground storage caverns in Germany. Next to a regions analysis for potential storage sites, the benchmarking against other large scale storage concepts, a comparative and perspective analysis of alkaline and PEM-electrolysers also potential business cases for Power-to-Hydrogen in the mobility sector as well as for the chemical, electricity and natural gas industry have been analysed. [German] Durch den geplanten Ausbau der Stromerzeugung aus fluktuierenden, erneuerbaren Energien in Deutschland ruecken Speichertechnologien fuer elektrische Energie immer staerker in den Fokus des industriellen und politischen Interesses. Eine vielversprechende Moeglichkeit fuer eine Langzeitspeicherung bei hohen Anteilen von Wind- und Photovoltaikanlagen sind Speichertechnologien wie die Wasserstoffspeicherung mit Hilfe von Wasserelektrolyseuren. Diese koennen erneuerbaren Strom in grossen Mengen und bei entsprechender Steuerung selektiv in Zeiten mit hohem Dargebot z.B. an Windstrom chemisch speichern. Der gespeicherte Wasserstoff kann dann entweder zu einem spaeteren Zeitpunkt wieder rueckverstromt oder direkt stofflich verwertet werden, z.B. als Kraftstoff fuer den Verkehrssektor, als chemischer Rohstoff oder fuer den Hausenergiebereich durch Einspeisung in das Erdgastransportnetz. Thema der vorliegenden Studie sind Analysen und Planungen fuer die Erprobung des Gesamtsystems ''Wasserstoff-Elektrolyse-Speicherung'' in energiewirtschaftlich relevanten Dimensionen. Dazu werden mit einem neuen Ansatz techno-oekonomische Entwicklungspfade fuer Wasserstoff-Systeme unterschiedlicher Groesse und Technologien charakterisiert und technologische Risiken bei der Realisierung dieser Systeme identifiziert und bewertet. Diese Arbeiten werden ergaenzt durch Arbeiten auf dem Gebiet der Salzkavernenspeicherung in Form von Untersuchungen vorhandener Salzkavernen sowie zu den Potenzialen und technologischen Anforderungen. Des Weiteren erfolgen modellbasierte Analysen der Integration der Wasserstofferzeugung und -nutzung in das zukuenftige Energiesystem bei hohen Anteilen erneuerbarer Energien aus verschiedenen energiewirtschaftlichen Perspektiven.

    The equivalent thermal conductivity of hollow block walls - using different kinds of mortar - was calculated as a factor of the thermal conductivity of the stone for ten different types of hollow stone. Improved dimensions were developed for brickwork with light-weight mortar as compared to brickwork connected with normal mortar. Depending on the stone dimensioning and type of stone the improvement of thermal conductivity lies between 0,03 W(mxK) and 0,07 W/(mxK) given a thermal conductivity of mortar of 0,30 W(mxK). If the latter is 0,15 W(mxK) it comes down to between 0,04 W(mxK) and 0,09 W(mxK).

This new approach having been readily adopted in practice, there already are many contracts reflecting the change in the mining industry's conception of itself, and experts wellcomed the turn away from the principle of 'tolerate and liquidate'.

    The revised version of the X-ray Ordinance came into force on January 1, 1988 (as announced in BGBl I, page 114), and bears so many and significant amendments that a complete revision of the commentary was to follow, especially with regard to the provisions in the medical field and on qualifications in radiological protection. This 2nd edition of the commentary adheres to the concept of the first, discussing the provisions from the legal and the medical point of view. More emphasis has been placed on practice-oriented explanations, so that specific legal interpretations have been compacted in order to give more space to practical advice to appliers of X-radiation. The commentary presents among others the Public Notices of BMA (the Federal Ministry of Labour and Social Affairs) concerning the X-ray Ordinance, as published in Bundesarbeitsblatt. These guidelines for implementation help radiation protection officers to appropriately interpret the new provisions on quality assurance and professional qualifications in the medical and technical fields, and to properly apply them in practice.

    630 women patients of the Bad Trissl clinic were admitted in 1987/88 to a prospective study to find out whether scintiscanning, or radionuclide imaging, of the skeleton can be omitted completely or in part in the after care and follow-up of carcinoma of the breast. The initial criterion was a postoperative carcinoma of the breast without metastasizing in the skeleton at the time the study began or the patient was admitted to the study. Careful pain anamnesis was performed by means of prepared questions, and a detailed clinical examination conducted to detect any pain in the skeleton of the patient concerned. This was followed by whole body scintiscanning of the skeleton and complementary X-ray films, if necessary additional examinations. It was found that clinical findings and imaging methods agreed in 545 patients. In 55 cases a finding that was clinically suspicious of metastases or doubtful, could be refuted by both scintiscan and by X-ray, osseous metastasizing would have been overlooked without skeleton scintiscan in 14 patients only (2.2%), 11 of these 14 patients were high-risk patients (negative hormonal receptor status, axillary lymph node metastases). Hence, it will be sufficient to employ scintiscanning in the aftercare and follow-up of carcinoma of the breast on a risk-adapted basis provided this is preceded by careful pain analysis and clinical examination. Failure to detect metastasizing in the skeleton will then occur in only 3 of 630 patients (0.48%). In this manner 40% of scintiscans can be omitted in future. (orig.).

    Female BDF/sub 1/-mice were used for the study. Even a BNU-concentration which in comparison to other authors was reduced from 0.04 to 0.02%, caused in a 12-week application in the drinking water leukemia in 96% of the mice. Additional X-radiation of 12x50 R and 4x100 R had no influence on the death rate. On the other hand, 12x25 R doses caused a significant acceleration and 12x75 R a significant delay in leukemogenesis by BNU. The leukemia incidence was not changed. The number of ETL increased in the groups with BNU and irradiation with the received radiation doses, whereas it decreased in the groups which were only irradiated. The groups which were only irradiated showed an increase in leukemia incidence with the received total dose. In the groups which were only irradiated the number of CFU/sub S/ and the thymus weight near the end of irradiation showed a good correlation with the leukemia incidence. In the groups with BNU and irradiation the superadditive effects in the collaboration of both noxae on immune status, thymus weight, and the stem cell number in the bone marrow and the spleen are confirmed. The extent of immunosuppression, bone marrow damage and thymus suppression is not correlated with the leukemia development.

    Management of the environment in the uranium mining industry has an eventful history of more than 50 years. In addition to examples of successful restoration of mining and preparation sites in some countries there are also numerous cases, in which no or defective restoration left behind serious waste deposits. In the course of the renaissance of the uranium industry there is increasing interest in the rehabilitation of such waste sites. There is still an urgent requirement to eradicate the environmental effects of the old mining industry. Previous deposits could be of interest for renewed working under the present economic boundary conditions. Restoration as an integral part of the current and future uranium mining industry with the application of modern international safety standards is extremely important. The contribution provides a survey of restoration projects of the old mining industry in various parts of the world and shows how the International Atomic Energy Agency, the national supervisory and approval authorities as well as the mining companies collaborate closely at many sites on solution of the difficult problems.

    The performance of Cu/sub x/S-CdS thin film solar cells can be improved significantly by a secondary treatment of the Cu layer. The physical mechanisms underlying the aftertreatment process were investigated both experimentally and theoretically. A historical review is followed by an outline of the technology and theory of these solar cells (material properties, process engineering, photovoltaic properties) and a description of Cu aftertreatment and H glowing (experimental set-up, surface potential shift, electron beam scanning). Capacity measurements in this type of thin film cell are described (space charge profile, electrolytic decomposition, copper depletion between the contact web). Aftertreatment of the copper layer enhances the solar cell efficiency, stability, and productivity, makes the immersion process less tedious, and corrects the stoichiometry. (HWJ).

    Arsenic is ubiquituously distributed in our environment and is subject to continuous bio-geochemical cycling. Besides the acute toxicity of arsenic its chronic effects are of special importance. The permanent uptake with drinking water for example might cause cancer. Today, arsenic compounds hardly serve as pesticides anymore, although chromated copper arsenate is still used to preserve wood. Furthermore, arsenic is used in the alloy, glass and semiconductor industry. The main part of the earths' arsenic resources are bound to sulfur in the lithosphere. By means of rock weathering and volcanism it is transferred into pedo-, hydro- and atmosphere, where it is mainly bound to oxygen. Microorganisms are able to methylate the arsenic, whereby gaseous arsenic compounds are carried into the atmosphere. Also, it is released from the lithosphere through anthropogenic mining activities, although only for a small part of the released amount useful applications exist. The arsenic behaviour in natural waters is closely related to sulfur on the one hand and to iron oxides on the other. Under strongly reducing conditions the arsenic is precipitated as sulfide, while under oxidising conditions it is adsorbed to the surfaces of iron oxides. Therefore, under aerobic conditions the arsenic concentrations of aqueous solutions are controlled by these adsorption processes rather than by the solubility of solid arsenic phases. Manganese oxides also play an important role as they are able to rapidly oxidise As(III) to As(V). These processes of release and fixation of arsenic in the nature must be studied carefully, because they are applied for arsenic elimination during drinking water production as well. (orig.)

    About 60% of the world's annual demand (500 bm{sup 3}) of hydrogen is provided by the reforming of fossil fuels. Regarding the limitation of fossil resources, the production of H{sub 2} from biogas becomes increasingly important. The GREEN-FC prototype for biogas conversion to hydrogen for fuel cells includes five modules: gas supply, gas purification, gas reforming, gas utilization and post-combustion. Operation parameters of the entire system have been optimized in order to maximize the H{sub 2} yield while limiting the CO content to avoid poisoning the HT-PEMFC. A replacement of modules is possible such that alternative reactors for biogas conversion and the further use of this concept can be studied. (orig.)

    Increasing the microstructural resistance of metallic materials to short fatigue crack growth is a major task of today's materials science. In this regard, grain boundaries and precipitates are well known to decelerate short cracks, but a quantitative understanding of the blocking effect is still missing. This is due to the fact that crack deceleration is influenced by many parameters: cyclic load, crack length, distance to obstacles, orientations of grains and obstacles. Even the examination of a huge number of short cracks would not be sufficient to identify the effect of these parameters independently, especially since fatigue crack growth is a 3D problem and investigations of the sub surface orientation of cracks and grain boundaries are scarce. The Focused Ion Beam Microscope (FIB) offers new methods for systematic experiments and 3D-investigation of short fatigue cracks that will help to quantify the microstructural impact on short fatigue crack growth. The ion beam is used to cut micro notches in selected grains on the surface of samples characterised by Electron Backscatter Diffraction (EBSD). Plane fatigue cracks initiate under cyclic loading in defined distances to the grain boundaries. By this technique it is possible for the first time to present quantitative data to describe the effect of grain boundaries on short fatigue cracks in nickel based superalloys (CMSX-4) as well as in mild steels.

    Purpose: To evaluate the suitability of different MR sequences for monitoring the stage of maturation of hyaline cartilage grafts in the knee joint and the early detection of complications like hypertrophy. In addition, it was analyzed whether indirect MR arthrography can indicate debonding of the graft. Materials and Methods: MRI examinations were performed in 19 patients, aged 17-43 years, with autologous transplantation of a hyaline cartilage tissue graft after knee trauma. Examination dates were prior to transplantation to localize the defect, and 6 weeks, 3, 6 and 12 months after transplantation to control morphology and maturation of the autologous graft. Standard T2- and protondensity-weighted turbo spin echo (TSE) sequences and T1-weighted spin echo (SE) sequences were used, as well as gradient echo (GRE) sequences with and without magnetization transfer (MT) prepulses. In some cases, indirect MR arthrography was performed. Results: Cartilage defect and the hyaline cartilage graft could be detected in all 19 patients. Hypertrophy of the graft could be found early in 3 patients and debonding in 1 patient. For depicting the graft a short time after surgery. T2-weighted TSE-sequences showed the best results. Six and 12 months after transplantation, spoiled 3D-GRE-sequences like FLASH3D (fast low angle shot) showed reduced artifacts due to magnetic residues from the surgery. Difference images from GRE-sequences with and without MT pulse provided high contrast between cartilage and surrounding tissue. The quantification of the MT effect showed an assimilation of the graft to the original cartilage within 12 months. Indirect MR arthrography showed subchondral contrast medium even 12 months after transplantation in 3 patients. (orig.)

    For the 15th time the German National Group of the Association Internationale du Droit Nucleaire/International Nuclear Law Association (AIDN/IN-LA) e.V. organised a regional conference. 90 participants from 15 countries, including representatives of Euratom and OECD/NEA, met in Bonn on 28 and 29 September to exchange views on current issues of nuclear law. The Rhine, which was in sight of the conference centre and connects countries, provided an excellent backdrop not only for the conference that connects nations, but also for the title of the conference ''Atomic Energy Law in Motion'' and for various lectures on nuclear transport.

  9. Microstructure and tribologic behaviour of metastable austenitic FeMn alloys as a function of chromium content; Gefuegeausbildung und Triboverhalten metastabiler austenitischer FeMn-Legierungen in Abhaengigkeit vom Chromgehalt

    In FeMn20Cr alloys with chromium contents of up to 20%, the solidification process is primarily an eutectic process. The {delta}-ferrite becomes increasingly instable below a temperature of 900 C and gradually disintegrates during slow cooling into austenite and a sigma phase. Tempering of these microstructures at T=450 C (6hours) leads to formation of {epsilon}-martensite in the austenite. Fast quenching starting above 900 C freezes the {delta}-ferrite, so that in the case of chromium contents between 13 and 18%, austenitic-hexagonal-ferritic microstructures form and above 18%, austenitic-ferritic microstructures. Tempering does not remove the {delta}-ferrite, but induces formation of {epsilon}-martensite in the austenite. Trobologic examinations with solutionized and water-quenched alloys showed, as compared to an FeMn20Cr18 alloy, for various types of wear, a very good tribologic performance (except for the alloy FeMn20Cr18 and cavitation). As to abrasion or hot wear, the formation of a sigma-phase or intercalation of metalloid hard phases should be considered. (orig./CB) [Deutsch] FeMn20Cr-Legierungen mit Chromgehalten bis zu 20% erstarren primaer ferritisch. Der {delta}-Ferrit ist unterhalb 900 C nicht mehr stabil und zerfaellt bei langsamer Abkuehlung in Austenit und Sigmaphase. Ein Anlassen dieser Gefuege T=450 C (6 Stunden) fuehrt zur {epsilon}-Martensitbildung im Austenit. Schnelles Abschrecken von oberhalb 900 C friert den {delta}-Ferrit ein, so dass bei Chromgehalten zwischen 13 und 18% austenitisch-hexagonal-ferritische und >18% austenitisch-ferritische Gefuege entstehen. Durch Anlassen kann der {delta}-Ferrit nicht beseitigt werden. Im Austenit kommt es aber zur {epsilon}-Martensitbildung. Tribologische Untersuchungen mit loesungsgegluehten und in Wasser abgeschreckten Legierungen zeigten im Vergleich zu einer FeCrNi-Legierung bei verschiedenen Verschleissarten (mit Ausnahme FeMn20Cr18 bei Kavitation) ein sehr gutes Triboverhalten. Gegenueber Abrasion oder Warmverschleiss sollte dann die Ausbildung der Sigmaphase bzw. die Einlagerung metalloider Hartphasen in Betracht gezogen werden. (orig.)

    Electrifying vehicle drives is a major part of Daimler's strategy to realize sustained mobility. Electrification encompasses a wide range of concepts and system designs - from the micro hybrid to the plug-in. Economically priced micro hybrids were initially available in the smart fortwo as well as A-Class and B-Class model series and will be successively offered for other model series. Mild and full hybrids, which feature additional functionality, have already been successfully launched or will be available in the near future. The effort to continually advance innovative drive technology culminates in the SClass Plug-In. The lithium-ion battery plays a key role with its high energy density and efficiency. These vehicles and the drive technology they incorporate make it possible to meet the most stringent emissions standards as well as achieve very low fuel economy and CO{sub 2} emissions. (orig.)

    With the establishment of its corporate image Ruhrkohle Bergbau AG has created the basis for the processes of change. One of the first steps in this direction was the organisational development process of the collieries. In the first phase the main emphasis was on the reduction of the hierarchy and the introduction of teamwork. The employees concerned were trained and assisted in accordance with their new tasks and competences. In the second phase of the change the main emphasis was more on the organisation with special consideration of the lower hierarchy levels. Greater orientation towards value creation was thus achieved. Meanwhile 50 TQM groups are working on the continuous improvement of the work processes within the framework of the `Total Quality Management` initiative at the Heinrich Robert colliery. The success of the intensive efforts in connection with TQM is reflected in the falling costs and the associated increase in profitability of the colliery. (orig.) [Deutsch] Mit der Einstellung des Unternehmensleitbildes hat die Ruhrkohle Bergbau AG die Grundlagen fuer Veraenderungsprozesse geschaffen. Einer der ersten Schritte in diese Richtung war der Organisationsentwicklungsprozess der Bergwerke. Ausgangsbasis hierzu waren umfangreiche Untersuchungen, bei denen unter Beteiligung der betroffenen Mitarbeiter Schwachstellen in der Organisation herausgearbeitet wurden. In der ersten Phase der Organisationsentwicklung lag der Schwerpunkt in der Beseitigung dieser Schwachstellen, die groesstenteils die Aufbaustruktur betrafen. Beispielhaft seien hier die Verflachung der Hierarchie und die Einfuehrung bereichsuebergreifender Teamarbeit genannt. Entsprechend ihren neuen Aufgaben und Kompetenzen wurden die betroffenen Mitarbeiter qualifiziert und unterstuetzt. In der zweiten Phase der Veraenderung wurde der Schwerpunkt mit besonderer Beruecksichtigung der unteren Hierarchieebenen mehr auf die Ablauforganisation gelegt. Damit gelang eine verstaerkte Orientierung zur Wertschoepfung. Auf dem Bergwerk Heinrich Robert arbeiten im Rahmen der Initiative `Qualitaet der Arbeit` inzwischen 50 QdA-Gruppen ausgerichtet auf die Ziele des Bergwerks an der kontinuierlichen Verbesserung der Arbeitsablaeufe. Die steigende Beteiligung der Mitarbeiter im Rahmen dieses QdA-Prozesses hat die Motivation und Arbeitszufriedenheit der Belegschaft in starkem Mass positiv beeinflusst. (orig.)

    We measured indicators of lead absorption (capillary blood lead, scalp hair lead and urine delta aminoleviolenic acid) as well as parameters of behavior and psychoperformance among three groups of children. These were 100, 100 and 76 children which constituted the total children of the fifth year of three primary schools from industrial, urban and rural areas respectively. The three indicators of lead absorption differed significantly between the three groups in the sense that: Indicators of those from industrial area > that of those from urban area > that of those from rural area. Psychological parameters showed a corresponding increased hyperactivity and lowered psychoperformance. The psychological parameters were significantly correlated with all the three indicators of lead absorption. In this domain hyperactivity scale was the most correlated one. The study confirms the opinion that environmental low lead level exposure constitutes a potential risk for behavioral and psycho-performance development among children with its possible negative consequences.

    The aim of the present study was to see whether HMPAO-SPECT may contribute to the differentiation between dementia of the Alzheimer type (DAT) and major depression (MD). The results in 77 patients with memory impairment were evaluated. 48 patients suffered from DAT and 29 from MD. Initially, the defects in SPECT imaging were attributed to a cerebral region and the degree of decrease was evaluated (-1/-2/-3). Thereafter, the results were classified by 7 categories. In some of these categories an accumulation of cases of either DAT or MD was found. 35% of the patients suffering from DAT had bilateral defects with distinct (>-1) parietal/parietotemporal hypoperfusions, but no patient with MD showed this perfusion pattern. 62% of the patients with MD had unilateral defects but only 31% of the patients with DAT. The present study demonstrates that only 35% of all patients suffering from DAT show a perfusion pattern, thought earlier as ''pathognomonic'' for this disease. This perfusion pattern - if it exists - may be used as a safe criterion to exclude MD. Beyond that no clearcut (''specific'') perfusion pattern may be recognized but unilateral defects point to MD.

    In 46 patients with dementia of the Alzheimer type (DAT) regional cerebral blood flow (rCBF) was compared with cognitive performance (MMSE, CAMCOG). The cortico-cerebellar ratio (CCR), determined by [sup 99m]Tc-HMPAO-SPECT was used as a rCBF-equivalent. In the mild demented group we found a bilateral CCR-reduction parietal posterior, in moderate DAT bilateral temporoparietal and leftsided frontolateral defects were seen. Severe DAT showed an additional perfusion decrease mid frontal. With increasing severity of DAT an asymmetric perfusion occurred in 17/46 patients with accentuated CCR-reduction on the left side (temporal>parietal). High correlations between CCR and MMSE (r[>=]0.70) existed frontolateral, temporal and parietal in the left hemisphere. Significant associations between CCR and CAMCOG were obtained for language in the left temporal posterior region (r=0.64), for memory task left temporal anterior (r=0.59) and for praxis left parietal posterior (r=0.55). In detecting rCBF abnormalities the sensitivity for all 46 DAT patients was 91% and 70% in the mild cases. (orig.)

    The carrying of an anti-nuclear-power badge by a teacher during school hours violates the order to practice reticence in political activities. At the beginning of 1977 some teachers, the plaintiff as well, carried anti-nuclear-power badges, i.e. a round badge with a stylized red sun on a yellow background with the inscription 'Nuclear power - No, thank you'. Following a general direction by the educational authorities, the headmistress forbade plaintiff on 4.11.77 to visibly carry this badge during lessons. This protest having been without success, action was brought with partial success at the Administrative and Higher Administrative Court. The Federal Administrative Court dismissed the case.

    The present book is an expedition across modern physics and simultaneously an illustrated voyage through the solved and unsolved enigmas of our universe. The twentieth century brought a manifold of physical discoveries. The atomic structure of matter was experimentally proved, and stepwise the structure of the atoms was decoded. Alber Einstein revolutionized with his special and general relativity theory our understanding of spca and time and unified so mechanic with electrodynamics and gravitation. Probably the most momentous upheaval learned our worldview by quantum mechanics. In the second half of the twentieth century by ever larger particle accelerators it was increasingly faced deeper penetrated into the structure of matter. Around the year 1967 it succeeded to answer the hereby occurring questions in the framework of the so-called Standard Model. Beside these fields also further partial fields of physics exist,which are not so closely connected with the inquiry of natural laws. We have four of these fields token in our book: Solid-state physics, geophysics, astronomy with astrophysics, as well as cosmology.

    Full Text Available The analysis of the consilium of the famous canonist Giovanni d’Andrea and three of his Bolognese colleagues from 9th May 1329 reveals that legal consilia in the fourteenth century were usually authenticated both with the signature and signum of the notary drafting the document and with the seals of the jurists. Three of the seal impressions formerly appended to the document illustrate in a strikingly similar fashion a detailed image widely disseminated on seals of jurists in medieval Italy: the doctor sitting enthroned in the cathedra, turned towards the viewer and at the same time concentrated on the open book in his hands. The image is a sympathetic visualisation of the basic scheme of the consultation of the legal doctors, i. e. the transmission of the theoretical legal knowledge of the studium to the world outside the university, which is exemplified in the text of the document in a specific casus. Seals of medieval jurists bear an effigy of the owner of the seal, like other seals of high-ranking persons, such as emperors, kings and bishops. Thereby, and by the insistent repetition of a picture form which can be distinguished clearly by its three dimensionally refined visual idiom from the seals of emperors, kings and bishops, the seals of doctors of law advertise themselves as sigilla authentica which enjoy absolute credibility.

    In the evening of January 14th, the public media came out with the news that also the NUKEM firm, which is the parent company of 'Transnuklear', is under strong suspicion of having violated the safety regulations of the Atomic Energy Act. The prosecution among others is investigating whether fissionable material has been illicitly transferred to Libya and Pakistan. In response to these suspicions that cast doubt upon the reliability of the NUKEM, the Federal Minister of the Environment has given order to suspend the operating licences of NUKEM for handling of fissionable material. The Federal Government and all political parties in the Bundestag unanimously are determined to investigate the case without restraint. The information leaflet in hand presents the statements given by the Federal Government, by the prime minister of Hesse, and by the political parties in the Bundestag. (orig./HSCH).

    On 11 March 2011 at 14.46 the strongest earthquake ever recorded in Japan struck the Pacific coast in front of Fukushima. The earthquake and the following tsunami damaged the nuclear power plants in Fukushima Dai-ichi to such an extent that the Japanese government declared the state of catastrophic accident with degree 7 according to the International Nuclear and Radiological Event Scale (INES). At Fukushima Dai-ichi there were 6 boiling water reactors (BWR), a storage pool for spent fuel assemblies and a dry cask storage. 12 km apart at Fukushima Dai-ni there were 4 more BWR. At the moment of the earthquake the reactors 1 to 3 of Fukushima Dai-ichi, as well as the 4 reactors at Fukushima Dai-ni, were at full power, while the reactors 4 to 6 of Fukushima Dai-ichi were shut down for revision. From 12 March 2011 on, fairly large quantities of radioactive materials were released from Fukushima Dai-ichi reactors with meaningful consequences on the population in the near neighbourhood. The irradiation from the radioactivity bearing clouds, the ingestion and inhalation, and the deposit of radioactive materials on the ground threatened the population. The inhabitants of large areas had to be evacuated. Furthermore, radioactive materials contaminated the drinking water, the sea water and finally the plants and animals, i.e. the food chain of the people living there. The Swiss Federal Nuclear Safety Inspectorate (ENSI) continuously proceeded with the evaluation of the situation in Japan and a specialists' team made a detailed analysis of the accident, with emphasis on the human and organisational factors and on the lessons learned from this. The present report describes the present knowledge about the radiological consequences of the accident in Fukushima Dai-ichi on the population in the neighbourhood and on the staff at the power plant, until October 2011. First, the unrolling of the accident and its consequences on the plant site are analysed according to international criteria. Then the transport of radioactive materials out of the reactors 1 to 3 is described and evaluated. The continuous mean discharge rate of radioactive materials is estimated and the treatment of the contaminated water accumulated in the power plant is explained. Through pressure release from the reactor containment and hydrogen explosions in the reactor buildings the released fission products gave rise to high dose rates on the plant site. The staff engaged on the plant was submitted to radiation exposure, what strongly worsened the working conditions. Because of the high radioactive background, the dosimetric surveillance was difficult. What regards the radiation exposure of the population in the neighbourhood of the plant through the released radioactive materials, in the first phase of the accident most of the dose was delivered through the crossing radioactive clouds and the inhaled radioactive dust. In the next phase the radioactive materials deposited on the ground contributed to a long-dated dose through external irradiation. Radioactive materials, which either directly or indirectly arrived on fodder plants and on greens, represent another important source of dose through ingestion. Besides, radioactive materials came into the food chain from lakes, rivers and sea through fish and sea fruits. Delivery of radioactive materials to surface waters contaminated drink water reservoirs and so contributed to higher radiation exposure. The Japanese government took measures to reduce the radiation exposure. The report also describes the effects of the Fukushima accident for the Swiss population and gives information on the most important measures and consequences for Switzerland. Finally the Fukushima accident is compared to the one in Chernobyl concerning the effects on the population and the environment. The release of radioactive materials at Chernobyl was 5 to 10 times higher than it was at Fukushima, and they were conveyed to much larger areas.

    The determination of the phytohormone abscisic acid (ABA) in needles of fir (Abies alba Mill.) is difficult due to the small amount of ABA and the large volume of phenolic and terpenoic compounds, which have similar structures compared with ABA. The quantitative analysis of ABA in purified extracts was not possible by HPLC because of deficient separation. A qualified method for exact quantification is gas chromatography using an electron capture detector. In this way ABA was completely separated from all other substances. Starting from the question, whether the content of secondary plant products of needles of Picea abies (L.) Karst. is influenced by damage, spruces from Wank Mountain were analysed. The needle concentrations of different compounds were influenced significantly by the class of damage as well as by the level of altitude. (orig.).

    Full Text Available [english] Aims: In this randomized comparative study, we obtained student evaluations for training with standardized patients as well as for computerized case simulations and correlated them with the student’s learning type. Training with standardized patients was also reviewed regarding acceptance.Methods: Medical students in the 5th clinical semester (N = 222 participated in a course with standardized patients (n = 99 or in computerized case simulations (n = 123. Following the course, the students completed a questionnaire including items concerning the methodology and didactics of both courses.Results: Training with standardized patients was evaluated as superior by the students. There was no correlation with the student’s learning type. Conclusions: The results show that it is possible to compare different methods of instruction in a controlled study. Both teaching methods provide the opportunity to practice clinical skills. Particularly in a neuropsychiatric setting, training with standardized patients can complement other methods as a means of developing communication skills.[german] Zielsetzung: Im Rahmen der vorliegenden Studie wurde der Einsatz von Standardisierten Patienten mit computerbasierten Falldemonstrationen in der psychiatrischen Lehre verglichen und die Bewertungen in Relation zu den Lernstilen der Studierenden gestellt. Darüber hinaus sollte die Akzeptanz von Standardisierten Patienten als innovative Lehrform überprüft werden.Methodik: Studierende des Regelstudiengangs Medizin im 5. klinischen Semester (N=222 nahmen entweder an einem Seminar mit Standardisierten Patienten (N=99 oder an einem Seminar mit computerbasierten Falldemonstrationen (N=123 teil. Im Anschluss an den Unterricht füllten die Studierenden einen Evaluationsbogen aus, welcher Fragen zur Bewertung der Methodik und der Didaktik beider Unterrichtsformen enthielt.Ergebnisse: Die Studenten gaben dem Fallunterricht mit Standardisierten Patienten in mehreren Bereichen signifikant bessere Bewertungen. Diese Einschätzung war unabhängig von den individuellen Lernstilen der Studierenden. Schlussfolgerung: Die Ergebnisse zeigen, dass der Vergleich unterschiedlicher Lehrmethoden in einer kontrollierten Studie möglich ist. Beide Unterrichtsformen bieten die Möglichkeit, praxisrelevante Fertigkeiten zu trainieren. Jedoch stellt gerade der Unterricht mit Standardisierten Patienten im Fachgebiet der Psychiatrie und Psychotherapie eine wichtige Ergänzung zu anderen Lehrmethoden dar, um kommunikative Kompetenzen im Umgang mit psychisch kranken Patienten einzuüben.

    Full Text Available Das moderne Strafrecht sollte informelle Geschlechternormen neutralisieren. Dies gelingt auch, kann aber bei der Strafzumessung unterlaufen werden. Wie der vorliegende Band in historisch ausgerichteten Einzelstudien zeigt, war das Strafrecht nie so objektivierend, wie es die Reformen seit den 1970er Jahren anstreben. Am Beispiel der Kindsmörderin wird nachgewiesen, dass der Verstoß gegen Geschlechtertugenden auch heute noch jederzeit mit harten Strafen sanktioniert werden kann.Modern criminal law should neutralize informal gender norms. This is by and large successful; however, it can be circumvented in the assessment of penalty. As shown by the historically orientated individual articles of this anthology, criminal law has never been as objectifying as the reforms since the 1970s are aspiring. Using the example of the female infanticide, the anthology proves that the violation of gender virtues can at all times still be sanctioned with severe penalties.

    Convoy-type nuclear power plant maintenance is subject to the specifications contained in the Technical Rules, as dated in the Annex, on the basis of the operating permits issued under Sec. 7 of the German Atomic Energy Act. The introduction of the Single European Market and the adoption of European directives in the field of equipment safety have influenced, and will continue to influence, the national legislative structure. Changes affecting convoy-type nuclear power plants can be found in the applicable laws and directives, such as the Atomic Energy Act, the Industrial Code, and in new regulations, such as the Equipment Safety Act with its associated ordinances, and the applicable engineered safeguards rules, such as KTA, AD, VdTUeV, VDI. Moreover, the generally recognized state of the art as laid down in DIN, SEL, SEW publications is subject to permanent European harmonization and, consequently, comprehensive national reorganization. These boundary conditions can be upheld only if the specifications about the advancing state of the art specified in the operating permits are put into effect painstakingly. The profile of requirements contained in these specifications must be aligned to the new situation in Germany (dominated by Europe) with the licensing authority and the competent expert consultant within the supervisory procedure for operation under the Atomic Energy Act. The situation described here for the modern convoy-type nuclear power plants must be extrapolated also to older nuclear power plants, albeit subject to a supplementary adaptation to the respective licensing situation. (orig.) [Deutsch] Fuer die Instanhaltung der Konvoi-Kernkraftwerke gelten die Spezifikationen mit dem in den Anhaengen datierten Stand der Technischen Regeln gemaess der auf Basis des AtG Paragraph 7 erteilten Betriebsgenehmigungen. Mit der Einfuehrung des Europaeischen Binnenmarktes und Verabschiedung Europaeischer Richtlinien auf dem Sektor der Geraetesicherheit wurde und wird auch die nationale gesetzliche Struktur beeinflusst. Dabei gibt es auch Veraenderungen fuer die Konvoi-Kernkraftwerke bei den zutreffenden Gesetzen und Richtlinien, wie Atomgesetz, Gewerbeordnung und neuen Geraetesicherheitsgesetz mit Verordnungen sowie den zugeordneten Regeln der Sicherheitstechnik, wie KTA, AD, VdTUeV, VDI. Des weiteren unterliegen die allgemein anerkannten Regeln der Technik, wie DIN, SEL, SEW, einer permanenten europaeischen Harmonisierung und damit einer umfassenden nationalen Reorganisation. Um in diesem Umfeld zu bestehen, sind diese Randbedingungen bei der Anpassung der in den Betriebsgenehmigungen festgelegten Spezifikationen zum fortschreitenden Stand der Technik sorgfaeltig umzusetzen. Das darin festgelegte Anforderungsprofil muss mit der Genehmigungsbehoerde und dem zugezogenen Sachverstaendigen im Rahmen des Aufsichtsverfahrens fuer den Betrieb nach AtG auf die neue Situation in Deutschland (dominiert von Europa) ausgerichtet werden. Die hier fuer die modernen Konvoi-Kernkraftwerke beschriebene Situation ist auch auf die aelteren Kernkraftwerke zu uebertragen, muss allerdings der jeweiligen Genehmigungssituation ergaenzend angepasst werden.

    zugefuehrt. Die Rebestrahlung, die beim makroskopischen Rezidiv einen hohen Stellenwert besitzt, wird nach erfolgter GTR aufgrund der Unkenntnis des raeumlichen Rezidivmusters, des Fehlens eines begruendeten Zielvolumenkonzepts und der Ungewissheit ueber die moegliche Effizienz dieser Behandlung zurueckgehalten. Klinische und bildgebende Daten von 26 Patienten nach GTR eines rGBM wurden untersucht. Die Bildanalyse erfolgte anhand der RANO-HGG-Kriterien (''response assessment in neuro-oncology criteria for high-grade gliomas''). Progressionsfreies (PFS) und Gesamtueberleben (OS) wurden mit der Kaplan-Meier-Methode ermittelt und die Daten durch ein systematisches Review untermauert. Alle bis auf 4 Patienten erhielten nach GTR eine Systemtherapie. In 20 von 26 Patienten kam es zu einem bildgebenden Progress, der in 70 % direkten Kontakt zur Resektionshoehle hatte. Die mediane Ausdehnung gemessen vom Resektionsrand lag bei 20 mm. Das PFS betrug 6 Monate, das OS 12,8 Monate. Wir empfehlen ein Zielvolumen mit Einschluss der Resektionshoehle einschliesslich aller Kontrastmittelaufnahmen als Gesamttumorvolumen (GTV), einen Saum vom 5-10 mm als klinisches Tumorvolumen (CTV) und einen lagerungsabhaengigen Saum von 1-3 mm als Planungszielvolumen (PTV). Eine Rebestrahlung mit diesem PTV kann grosse Teile der spaeteren Rezidivregionen erfassen und so moeglicherweise das PFS erhoehen. Die fruehe Rebestahlung nach GTR sollte in Erwaegung gezogen werden, da die Bestrahlung eines schmalen Saums um die Resektionshoehle gut und sicher durchfuehrbar ist. Die fruehe Rebestahlung nach GTR wird aktuell in der GlioCave/NOA-17/Aro-2016/03-Studie untersucht. (orig.)

    Therapieformen. In der vorliegenden Untersuchung wird sein Einfluss auf die Akuttoxizitaet der alleinigen Strahlen- bzw. kombinierten Radiochemotherapie bei Patienten mit fortgeschrittenen Kopf-Hals-Tumoren ueberprueft. Patienten und Methodik: Es wurden 23 Patienten mit fortgeschrittenen Kopf-Hals-Tumoren, ueberwiegend im Stadium III und IV, mit praeoperativer Radiatio (n=1), prae- und postoperativer Radiatio (n=5), postoperativer Radiatio (n=11) bzw. kombinierter Radiochemotherapie (n=6) behandelt. Vor jeder Behandlung wurden 500 mg Amifostin intravenoes ueber 15 Minuten verabreicht. Die Therapiedokumentation dieser unselektierten Patientengruppe wurde retrospektiv mit einem historischen Patientenkollektiv verglichen, das 17 Patienten umfasste. Resultate: Bei 15 Patienten (65%) unter Amifostin kam es zu therapiebedingten Nebenwirkungen wie Mukositis und Dermatitis {<=}WHO-Grad 2, welche Radiotherapiepausen (Mittelwert: 6,5, maximal 17 Tage) erforderten. Schleimhaut- bzw. dermatoligische Nebenwirkungen vom WHO-Grad 3 oder 4 wurde bei keinem Patienten beobachtet. In der historischen Kontrollgruppe trat eine signifikant hoehere Akuttoxizitaet auf. Eine Stomatitis oder Epitheliolyse vom WHO-Grad 3 wurde bei sieben Patienten (41%) beobachtet. Bei 15 Patienten (88%) erforderten die therapiebedingten Nebenwirkungen Radiotherapiepausen (Mittelwert: 16, maximal 40 Tage; p=0,0016). Schlussfolgerung: Die zusaetzliche Gabe von Amifostin vor jeder Bestrahlung scheint in einer deutlichen Reduktion der Akuttoxizitaet bei der Strahlen- bzw. kombinierten Strahlen-/Chemotherapie bei Patienten mit Kopf-Hals-Tumoren zu resultieren und eine zeitgerechtere Applikation zu ermoeglichen.

(orig.) [German] In der Vergangenheit wurden an Biogasmotoren immer wieder Grenzwertueberschreitungen der in der Technischen Anweisung zur Reinhaltung der Luft (TA Luft) limitierten Formaldehydemissionen festgestellt. Fuer die zukuenftige Einhaltung dieses Grenzwertes an bestehenden und neuen Anlagen wurden am Lehrstuhl fuer Verbrennungskraftmaschinen der Technischen Universitaet Muenchen im Rahmen des FVV-Forschungsvorhabens 918 die Ursachen und die Moeglichkeiten zur innermotorischen Verminderung dieser Emissionen untersucht. Dabei zeigte sich, dass die Formaldehydemissionen nur sehr eingeschraenkt durch innermotorische Massnahmen verringert werden koennen, ohne Wirkungsgrad und Stickoxidemissionen negativ zu beeinflussen. Dies und eine zusaetzliche Verschaerfung der Grenzwerte im Januar 2009 durch LAI-Beschluss machen den Einsatz von Abgasnachbehandlungstechniken notwendig. Wegen der fehlenden Datenbasis ueber das Langzeitverhalten solcher Systeme im Biogasbetrieb wurden deshalb in einem weiteren Vorhaben zwei Modellanlagen mit unterschiedlichen Technologien zur Abgasnachbehandlung ueber sechs Monate hinweg hinsichtlich ihrer Formaldehydemissionen ueberwacht. Im Hinblick auf die aktuelle Klimadebatte und die Klimawirksamkeit von Methan, die eine zukuenftige Begrenzung dieser Emissionen erwarten laesst, wurden darueber hinaus auch die Methanemissionen dieser Anlagen untersucht. Die Untersuchungen zeigten, dass beide betrachteten Abgasnachbehandlungstechnologien, Regenerative Thermische Oxidation (RTO) und Oxidationskatalysator (Oxi-Kat) grundsaetzlich geeignet sind, die geltenden Formaldehydgrenzwerte sicher zu unterschreiten. Es wurde jedoch auch klar, dass weiterer Forschungsbedarf hinsichtlich der Dauerhaltbarkeit des Oxi-Kats und dem Instationaerbetrieb des RTO

    verursachte. Wie Leuschner feststellt, waere der Schaltungsfehler der EON-Netzleitstelle Lehrte vor ein paar Jahren noch vom System toleriert worden. Er habe nur deshalb so gravierende Folgen haben koennen, weil das UCTE-Netz inzwischen durch den Stromhandel und andere Folgen der Deregulierung bis an die Grenzen seiner Kapazitaet belastet sei. Im dritten Teil (''Netznutzung und Netzentgelte'') beleuchtet er in einem zusaetzlichen Kapitel die Bemuehungen der EU-Kommission, doch noch die Rahmenbedingungen fuer echten Wettbewerb herzustellen. Die neueste Forderung der Kommission nach eigentumsmaessiger Entflechtung der Netze deutet er als ''Flucht nach vorn'' angesichts der Tatsache, dass in saemtlichen EU-Laendern seit der Liberalisierung die Strompreise gestiegen sind und das zum Teil sogar ueber die Haelfte (mit der einzigen Ausnahme Englands, und hier auch nur der Haushaltsstrompreise). Kraeftig erweitert hat der Verfasser auch den vierten Teil zum Thema ''Management und Politik'': Zum einen findet man hier nun beschrieben, wie Ex-Bundeskanzler Gerhard Schroeder einen Spitzenjob beim russischen Energiekonzern Gazprom erhielt, dem er bereits in seiner Amtszeit als Bundeskanzler politisch behilflich war, und wie sein ehemaliger Wirtschaftsminister Wolfgang Clement in den Aufsichtsrat von RWE Power einziehen durfte. Zum anderen wird ein kritischer Blick auf die Werbekampagnen geworfen, mit denen die Energiekonzerne versuchen, ihr Erscheinungsbild in der Oeffentlichkeit aufzuhellen und den Energieverbrauchern ein X fuer ein U vorzumachen.

Die ESTRO-QUARTS- und IAEA-Richtlinien wurden angewandt, um den Bedarf fuer Teletherapie-(TRT-)Einheiten, Radioonkologen (RO), Medizinphysiker (MP) und Medizinisch-technische Radiologieassistenten (RTT) abzuschaetzen. Die Datenbanken, die fuer die Errechnung der gegenwaertigen Luecke und die zusaetzlichen Anforderungen verwendet wurden, sind (a) GLOBOCAN (Global Cancer Incidence, Mortality and Prevalence) fuer die Krebsinzidenz, (b) das Verzeichnis der Bestrahlungszentren (DIRAC, Directory of Radiotherapy Centres) der IAEA (International Atomic Energy Agency) fuer bestehende TRT-Einheiten, (c) die neueste ESTRO-HERO-Studie (European Society of Therapeutic Radiation Oncology - Health Economics in Radiation Oncology) fuer die Personalausstattung und (d) Daten vom Ingham Institute for Applied Medical Research (IIAMR) ueber den Grad der Bestrahlungstherapieauslastung (RTU) fuer jede Krebsart. Im Jahr 2015 haetten 30.999 von 45.903 Krebspatienten eine Bestrahlung benoetigt. Bis 2020 wird diese Zahl auf 34.041 von 50.427 Krebspatienten steigen. Die Schweiz verfuegt zwar momentan ueber eine ausreichende Anzahl an TRT-Einheiten, weist aber einen Mangel von 57 ROs, 14 MPs und 36 RTTs auf. Bis 2020 werden zusaetzlich 7 TRT-Einheiten, 72 ROs, 22 MPs und 66 RTTs benoetigt. Zusaetzlich wurde ein wirklichkeitsnahes, dynamisches Modell vorgeschlagen, um den Bedarf an Personal aufgrund von kuenftig zu erwartenden Aenderungen in den Bestrahlungstherapietechniken zu errechnen.

    anaplastischen Meningeomen gezeigt werden. Eine weitere erfolgreiche therapeutische Option von Bevacizumab scheint die Behandlung der Radionekrose zu sein. Die Effekte einer solchen antiangiogenen Therapie auf die MR-Diffusion und -Perfusion sind bisher bei Meningeomen noch nicht im Detail beschrieben worden. Unser Ziel war es, klinische und MR-Effekte unter Bevacizumab-Therapie bei einer Patientin mit malignem Meningeom und zusaetzlicher Radionekrose nach wiederholter Bestrahlung zu beschreiben. Wir berichten ueber eine 80-jaehrige Frau, die Bevacizumab (5 mg/kg alle 2 Wochen fuer 2 Monate) zur Behandlung einer symptomatischen Radionekrose nach wiederholter Bestrahlung bei Vorliegen einer malignen Meningeomatose vom WHO-Grad III erhielt. Die Patientin wurde engmaschig magnetresonanztomographisch einschliesslich Diffusions- und Perfusionsstudien kontrolliert. Unter Bevacizumab wurde die klinische Situation ueber einen Zeitraum von 4 Monaten zunaechst gut stabilisiert, bis die Patientin leider im Rahmen einer Sepsis nach Pneumonie - wahrscheinlich unabhaengig von der Bevacizumab-Therapie - verstarb. Die MRT-Untersuchungen zeigten folgende 4 wichtige Aspekte: (1) erheblicher Rueckgang der Kontrastmittel-(KM-)aufnehmenden Radionekrose, (2) gemischte Reaktion in Bezug auf die Meningeomatose mit stabilen, aber ueberwiegend progredienten Tumorlaesionen, (3) Auftreten einer neuen diffusionsgestoerten Laesion in einem KM-aufnehmenden Tumorknoten, wie es auch in Gliomen unter Bevacizumab beschrieben worden ist, die wir hier aber nicht als Reaktion auf die Bevacizumab-Therapie interpretieren, und (4) neue thrombembolische Infarkte, die als Nebenwirkung einer Bevacizumab-Therapie bekannt sind. Bevacizumab ist bei der Behandlung der Strahlennekrose gut wirksam. Wir konnten in unserem Fall einer malignen Meningeomatose aber nicht die potentielle antitumoroese Wirkung von Bevacizumab bestaetigen. Allerdings konnten wir mehrere neue MRT-Effekte unter Bevacizumab-Therapie bei einem malignen

    During the past few years, the waste industry changed from waste disposal to a waste recycling and power industry. As global resources are being depleted, the potential of waste materials must be realized more fully. The new biofermentation plant at Backnang-Neuschoental is an example. Since October 2011, all biowastes of the Rems-Murr district have been processed in the plant, with optimum utilization of the energetic potential. The biogas produced during fermentation generates about 8.6 million kW of electric power that is supplied to the public power grid. The waste heat of the power generation process is utilized in the nearby sewage sludge drying plant of the town of Backnang. This near-ideal concept saves more than 7000,000 l of heating oil per annum formerly used for drying up to 15,000 tonnes of sewage sludge. Together with the eco-power generation process, this results in a CO{sub 2} reduction potential of up to 8,000 tonnes per annum, which is a big step for climate protection in the Rems-Murr district. The eco-balance of the plant is made even more favourable by a PV system of about 197 kW{sub peak} on the roofs of the industrial halls. The organic waste collected in the 'brown bio-bin' is treated by qualified biological processes, and high-grade organic fertilizers and humus are obtained to close the natural cycle of materials. More than 15,000 tonnes of liquid fertilizer and about 10,000 tonnes of biocompost are produced every year; these are subject to constant independent quality control and are sold to agricultural and horticultural buyers.

    On 3 February 2001 the European Commission adopted the new Community guidelines on state aid for environmental protection. These guidelines outline the methods and criteria used by the Commission when controlling environmental state aid according to Art. 87 and 88 of the EC-Treaty. The study analyses the development of the new guidelines and their potential effects on environmental protection and environmental policy in the Member States of the European Union. In essence, the guidelines display three harmful tendencies: - they hamper progressive and innovative environmental policy that improves on 'least common denominator'-Community standards; - they do not respect the limits of the Commissions's authority, and interfere with the Member States' exclusive authority to decide on strategies and instruments of their respective environmental policies, and they especially affect Member States' choices between different energy sources and the general structure of its energy supply; - finally, they do not improve the protection of air competition on the common market. Based on these findings, the report delineates perspectives for an aid control policy that protects fair competition, and that gives incentives for voluntary national and regional environmental protection, allows for the equal treatment of clean techniques, and provides a consistent framework for exemptions from ecological taxes and environmental levies at the same time.

    In the framework of this thesis mono- and oligonuclear Cu(II)- anf Ni(II)-bis(oxamato) complexes are synthesized in view on their magneto-optical properties and structurally characterized. About transition-charge and transition-metal induced deviations from the general reaction behaviour described in literature is reported. From electron-spin-resonance studies the spin-density distribution in the mononuclear Cu(II) complexes is derived. The influence on this by coordination geometry as well as the effects of the superexchange interaction are discussed and compared with results from the density functional theory (DFT). Trinuclear bis(oxamato) complexes are for the first time deposited on Si(111) substrates by spin coating and studied by means of the spectroscopic ellipsometry as well as the Raman spectroscopy and evaluated by means of DFT calculations. Magneto-optical Kerr-effect studies were performed on thin layers of these complexes as well as phthalocyanines. For the comparison the magnetic and magneto-optical properties of Ni nanoparticles in different organic matrices were studied. By means of the photoelectron spectroscopy the oxidation behaviour of these is studied and conclusions on charge-transfer processes between the matrices and the nanoparticles are drawn. [German] Im Rahmen dieser Arbeit werden ein- und mehrkernige Cu(II)- und Ni(II)-bis-(oxamato)-Komplexe im Hinblick auf ihre magneto-optischen Eigenschaften gezielt hergestellt und strukturell charakterisiert. Ueber ladungs- und uebergangsmetallinduzierte Abweichungen vom allgemeinen in der Literatur beschriebenen Reaktionsverhalten wird berichtet. Aus Elektronenspinresonanz-Untersuchungen wird die Spindichteverteilung in den einkernigen Cu(II)-Komplexen abgeleitet. Die Beeinflussung dieser durch die Koordinationsgeometrie sowie die Auswirkungen auf die Superaustausch- Wechselwirkung werden diskutiert und mit Ergebnissen der Dichtefunktionaltheorie (DFT) verglichen.

    Field design changed substantially from extended-field RT (EF-RT) to involved-field RT (IF-RT) and now to involved-node RT (IN-RT) and involved-site RT (IS-RT) as well as treatment techniques in radiotherapy (RT) of Hodgkin's lymphoma (HL). The purpose of this article is to demonstrate the establishment of a quality assurance program (QAP) including modern RT techniques and field designs within the German Hodgkin Study Group (GHSG). In the era of modern conformal RT, this QAP had to be fundamentally adapted and a new evaluation process has been intensively discussed by the radiotherapeutic expert panel of the GHSG. The expert panel developed guidelines and criteria to analyse ''modern'' field designs and treatment techniques. This work is based on a dataset of 11 patients treated within the sixth study generation (HD16-17). To develop a QAP of ''modern RT'', the expert panel defined criteria for analysing current RT procedures. The consensus of a modified QAP in ongoing and future trials is presented. With this schedule, the QAP of the GHSG could serve as a model for other study groups. (orig.) [German] Nicht nur die Zielvolumendefinitionen haben sich von der Extended-Field- (EF-RT) ueber die Involved-Field- (IF-RT) bis zur Involved-Node- (IN-RT) und Involved-Site-Radiotherapie (IS-RT) weiterentwickelt.

    Aortic isthmus stenosis is the most common congenital aortic anomaly and is often a problem for therapy surveillance. In addition to possible comorbidities (e.g. bicuspid aortic valve) it is accompanied by various middle and long-term complications depending on the primary choice of the therapeutic procedure. Magnetic resonance imaging (MRI) plays an important role for the mostly young patients in the control of the aortic isthmus stenosis and therapy because it is non-invasive and there is no X-ray exposure. Radiologists should be well-informed on the principles of the therapeutic procedure in order to be competent in the interpretation of MRI findings. Due to the continuous development of MRI technology, techniques for functional evaluation (e.g. dynamic MRA, 4D PC flow measurement) are increasingly becoming available in addition to high-resolution MR angiography (MRA), which could predict the risk of possible complications, such as aneurysms. However, in this aspect further studies are necessary. Interventional therapy with stents and stent grafts is often employed for the therapy of possible complications following an operation (aneurysms, restenosis) but because of massive metal artefacts the use of MRI is often sometimes severely limited. (orig.) [German] Die Aortenisthmusstenose als haeufigste angeborene Aortenanomalie stellt ein haeufiges Problem der Therapieueberwachung dar und ist neben moeglichen begleitenden Anomalien (z. B. bikuspidale Aortenklappe) in Abhaengigkeit vom primaer gewaehlten Therapieverfahren mit verschiedenen Komplikationen im mittel- bis laengerfristigem Verlauf vergesellschaftet. Bei der Kontrolle der Aortenisthmusstenose bzw. deren Therapie spielt die Magnetresonanztomographie (MRT) aufgrund der Nichtinvasivitaet und fehlenden Strahlenexposition bei den meist juengeren Patienten eine wichtige Rolle. Der Radiologe sollte ueber die Grundzuege der Therapieverfahren informiert sein, um die MRT-Befunde kompetent zu befunden. Durch stetige

    For thousands of years, all cultures of man have described and researched life energy, whether they called it Qi, Chi, Prana, Od or Orgon. Since Rupert Sheldrake published his theory of morphogenetic fields, the subject has been accessible to the population in general and is contributing to the decline of the current paradigm of science. Knowledge that seamed indisputable since the time of Newton and Descartes is waning, and science must restructure itself on quite a different basis. Einstein, too, is becoming history. The book spans the discoveries of Lord Kelvin to Nikola Tesla to Prof. Dr.-Ing. K. Meyl whose potential eddy theory leads to a new understanding of the world. The key to this is the neutrino, and the fundamentals of neutrino physics are quite simple: At every moment, more than 60 thousand millions of neutrinos flow through us, controlling everything that exists. In his book, author Walter Haege shows how we can all utilise this indispensable neutrino power. It is a book for everyday practice, an indispensable reference manual for all those who intend a radical change in their view of the world and their way of living. (orig.) [German] Seit Jahrtausenden wird in allen Kulturen jene Energie beschrieben und erforscht, die uns steuert und unsere Zeit am Leben erhaelt, jene Energie mit den vielen Namen, von denen uns die bekanntesten, Qi, Chi, Prana, Od oder Orgon vielleicht gelaeufig sind.

    A hybrid wind-photovoltaic system has been operated in the Zentrallager of the Plus-Warenhandelsgesellschaft in Ottendorf-Okrilla (Saxony) since 1992. A 60 kW wind energy converter of Tackes TW-60 type has been combined with a 3.18 kW photovoltaic system. Some special features of the pv system (orientation of the generator, master-slave operation of the inverters) are remarkable. The operation of both systems was investigated in detail. With a yield of 689 kWh/kW{sub p}a in 1995 the pv system achieved comparable results with other grid coupled pv systems in Saxony. Possible better results are prevented by the selected generator orientation. The master-slave mode of the inverter was studied in detail. The nonoptimal relation between the generator size and the inverters influenced the results. The wind energy converter achieved in 1995 a yield of 990 kWh/kW, which is below average also for non coast areas. The result is influenced by many obstacles in the surrounding of the converter. The time availability of the hybrid energy system in 1995 was 71.5% (6260 hours). (orig.)

    Purpose: To describe the incidence, time course, and clinical correlates of hemorrhagic transformation (HT) of ischemic stroke in the posterior cerebral artery territory. Methods: Within 42 months 48 patients with 52 occipital lobe infarctions were examined by T{sub 1}- and T{sub 2}-weighted MR imaging. The extent and distribution of secondary hemorrhage were analysed at different intervals after stroke. Volume of ischemic and hemorrhagic infarction was measured planimetrically. Results: HT was observed in 71% of the infarcts between the 5{sup th} day and up to 1 year after stroke. HT was most frequently (88%) observed in the 2{sup nd} and 3{sup rd} month. HT was present in 55% of small infarcts (<10 cm{sup 3}), in 88% of medium size (10-50 cm{sup 3}), and in all large (>50 cm{sup 3}) infarcts. In 92% HT presented with petechial bleedings within the cortex (64%) or less frequently (28%) in subcortical structures. The latter types of HT showed no progression and did not increase the clinical deficits. Space-occupying bleedings occurred in only two large defects. Conclusions: In ischemic posterior infarction, HT can frequently be detected within the first three months after stroke and is predominantly of the petechial type and seems not to be relevant with regard to clinical deficits.

    In this thesis polymer-metal nanocomposites were fabricated by simultaneous sputtering of silver and polymers from two independent magnetron sputtering sources. By the netted structure and the dielectric properties PTFE is suited for the use as matrix material. The metal content of the composite films was determined via the measurement of EDX intensities. The size of the nanoparticles was determined by means of TEM and XRD and lies in the range of 10 nm. The composite materials show at the percolation limit a sudden transition of the properties from polymer- to metal-like behaviour. The specific resistance decreases in a range between 35 and 40 % silver content by at least nine orders of magnitude. The optical properties change with the metal content. The absorption caused by plasmon resonance, which has at small filling degrees its maximum at about 000 nm and has an intense yellow colour of the composite material as consequence shifts with increasing silver content to longer wavelengths. The difference in the optical.behaviour of the nanocomposites and the pure polymers can be used for the fabrication of Bragg reflectors. Small changes in the metal content can in the polymer-silver nanocomposites in the range of the percolation threshold effect a drastic change in ther properties, by which applications as sensors are thinkable.

Der Metallgehalt der Kompositfilme wurde ueber die Messung von EDX-Intensitaeten ermittelt. Die Groesse der Nanopartikel wurde mit Hilfe von TEM und XRD bestimmt und liegt im Bereich von 10 nm. Die Kompositmaterialien zeigen an der Perkolationsgrenze einen schlagartigen Uebergang der Eigenschaften vom polymer- zum metallaehnlichen Verhalten. Der

    Actual molecular strategies in therapy of lymphoma attempt to utilize the immune system to target and eliminate residual lymphoma cells after first line therapy. Therefore lymphoma-specific vaccines are used. Therapy was already successful in vitro, in vivo studies are planned for the near future. In the past two decades, prognosis of lymphoma patients has improved due to advances in staging as well as in therapy control. The introduction of duplex sonography allows the decision on dignity of suspicious lymph nodes not only by size criteria but also by different perfusion pattern. Similar advances have been made in cross sectional imaging like computed tomography and magnetic resonance imaging. The development of lymph node specific contrast agents present new tools for further investigation. In nuclear medicine, functional imaging using positron-emission tomography presents new perspectives especially in diagnosis and treatment control of malignant lymphoma. The visualization of the glucose metabolism using the radiolabeled glucose analogue fluorodeoxyglucose (FDG) allows the detection of involved lymph nodes independent of arbitrary criteria such as lesion diameter. First studies on the use of FDG-PET in staging and restaging of lymphoma patients show promising results. (orig.) [Deutsch] Das 2.

    Detecting thin layers of chemicals covering the sea bottom with existing techniques is not feasible. Scanning an area for possible polluted sea bottom eg. with SONAR-based acoustical measurements requires a pointwise operation. The acoustical measurement technique proposed here scans the sediment surface and allows for the qualitative contamination estimation for distances up to approx. 100 m away from the sensor. Experiments in the laboratory as well as field experiments have been undertaken, where a comparable but riskless contamination method was used. Both scenarios show the same change in the acoustical transmission when thin layers of pollutants cover the sediment. A numerical verification of the observed effects was done. The prototype of the detector system consists of a autonomous acoustical transponder to be deployed separately from the acoustical sensor equipped with an array of hydrophones that can be mounted on a ROV (remotely operated vehicle). Newly developed hydrophones provide an optimalized shielding of ambient noise. The system was designed for a mobile operation on board a ship. A stationary operation eg. in endangered harbor areas or rivers is possible, where a permanent supervision of the sediment layer is required. The necessary modification of the sensor system for this task can be done without additional development. (orig.)

    The liver is the second only to lymph nodes as the most common site of metastatic disease irrespective of the primary tumor. Up to 50% of all patients with malignant diseases will develop liver metastases with a significant morbidity and mortality. Although the surgical resection leads to an improvement of the survival time, only approximately 20% of the patients are eligible for surgical intervention. Radiofrequency (RF) ablation represents one of the most important alternatives as well as complementary methods for the therapy of liver metastases. RF ablation can lead in a selected patient group to a palliation or to an increased life expectancy. RF ablation appears either safer (vs. cryotherapy) or easier (vs. laser) or more effective (percutaneous ethanol instillation [PEI]), transarterial chemoembolisation [TACE] in comparison with other minimal invasive procedures. RF ablation can be performed percutaneously, laparoscopically or intraoperatively and may be combined with chemotherapy as well as with surgical resection. Permanent technical improvements of RF systems, a better understanding of the underlying electrophysiological principles and an interdisciplinary approach will lead to a prognosis improvement in patients with liver metastases.

    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.)

    The present report contains the result of a research project on `Technology assessment with regard to the environment` which was commissioned by the Federal Ministry for Research and Technology (BMFT) and carried out jointly by the GSF Research Centre for Environment and Health (GSF) and the Institute for Applied Innovation Research (IAI). In this project the Law on Protection from Harzardous Substances (Law on Chemicals) was used to exemplify the procedure of assessing the consequences of legislation in the area of environmental law. The project proposal distinguished three project phases. In the first an exemplary ex post analysis was to be carried out on a significant legal regulation (the Law on Chemicals) concerning a specific branch of industry generally considered innovative (the chemical industry). In this way it was intended to collect empirical knowledge on how regulations affect innovation processes in the individual company. In the second phase the planned amendment of the Law on Chemicals was to serve as a case example for an assessment of the consequences of legislation. In the third project phase the methodology employed in the former was to be extended for the purpose of developing an instrumentarium for the ex ante assessment of legislation. Such an instrument could permit both the corporate innovator and the innovation promoter to assess the effets of environmental legislation at the corporate level and thus develop an anticipatory conflict management.

    Purpose: To study the time and mode of the development of the colliculus atlantis, the rate of its occurrence, the causes for its absence, and the radiological-clinical importance in the analysis of open-mouth-view radiographs. Material and Methods: Retrospective analysis of standardized radiographs of the cervical spine in more than 20 000 adults and 100 children. Study of 234 human skeletons of different ages and of 38 isolated adult atlases. Cadaveric dissection of 42 adults (age 48-87). Axial radiographs of isolated atlases and analysis of the bony structures of the colliculus atlantis. Results: The colliculus atlantis develops between age 10 and 13 years. It is always present after age 13 years. For the development of the colliculus atlantis a normal function of the craniocervical joints is necessary. In congenital dysmorphias of the craniocervical region with dysfunction of the craniocervical joints and in fractures of the dens axis before age 10 years with instable healing the colliculus atlantis is absent. Conclusions: The colliculus atlantis is developed at age 13 years apart from some rare exceptions as mentioned. Changes of the site and the structure of the colliculus atlantis allow an early diagnosis of certain traumatically and inflammatory diseases of this region. Furthermore, it serves as an additional parameter in functional analysis of the craniocervical joints. (orig.)

    This conference was held at Garching near Munich on June 18 - 20, 2001. Legal and political aspects were discussed, i.e. new national and international legislation and the implementation of EC regulations into German law, e.g. in the fields of waste dumping, incineration, and 'best technology'. Refuse-derived fuels are gone into, e.g. construction site waste, residues of the paper industry, plastic waste, sorted waste fractions, waste oil, animal meal, etc., as well as technologies and plants for co-combustion of refuse-derived fuels. Another section discussed 'classic' incinerators and their optimisation and innovation potential. Selected new concepts for furnaces, boilers, corrosion reduction and flue gas purification were discussed. Not least, the cost aspect is getting increasingly important. Benchmarking and the internet are addressed. The conference has become an important forum for producers, operators, planners and consultants, administrators and scientists in the field of thermal waste management. [German] Vom 18. bis 20. Juni 2001 fand in Garching bei Muenchen wieder die Fachtagung 'Thermische Abfallbehandlung' statt. Der rechtliche und politische Rahmen wird von den neuen nationalen und internationalen Gesetzen und Verordnungen gepraegt, vor allem durch die Umsetzung mehrerer europaeischer Richtlinien in deutsches Recht, beispielsweise zur Abfalldeponierung, zur Verbrennung von Abfaellen sowie zur bestverfuegbaren Technik. Ein grosser Themenblock ist dem Brennstoff aus Muell gewidmet, welcher bereits vor ueber zwanzig Jahren ein grosses Thema war. Mittlerweile scheinen Ersatz- und Sekundaerbrennstoffe fuer viele der Koenigsweg bei der Loesung der abfallwirtschaftlichen Probleme zu sein. Daher sind hier ausfuehrliche Informationen zu etlichen potenziellen Brennstoffen wie Baustellenabfaelle, Spuckstoffe aus der Papierindustrie, Kunststoffabfaelle, DSD-Sortierreste, Altoel, Tiermehl usw. zu finden.

    From 2005, the TA Siedlungsabfall (Waste Management Regulation) will come into force, and European legislation will overrule national legislation. Dumping of untreated waste in landfills will be prohibited, i.e. incinerators for thermal waste treatment must be constructed. In view of the rigid specifications for emissions and residues and the demand for Europe-wide invitations for tender, time is running short. The book outlines the options for action of the German states and of some applicant states for EC membership. The German government already issued an Ordinance for Power Generation from Biomass. Independent of this, also secondary fuels are gaining ground, and several contributions of the conference discussed quality assurance and utilization of secondary fuels. Composting and sewage sludge utilization are further current issues. Air pollution, soil and groundwater protection, job security and energy potential are gone into, and an outline of the current situation of waste management is attempted. [German] Die aktuelle abfallwirtschaftliche Situation wird in besonderem Masse gepraegt durch das nahende Jahr 2005 sowie die zunehmende Abhaengigkeit nationalstaatlicher Handlungsspielraeume von den Vorgaben europaeischer Rahmenrichtlinien. Hierbei wird der Handlungsdruck spuerbar, spaetestens ab dem Jahr 2005 der TA Siedlungsabfall Rechnung tragen zu muessen. Die verbleibenden Zeitraeume sind daher eng bemessen, beruecksichtigt man insbesondere die langen Genehmigungs- und Errichtungszeitraeume fuer thermische Behandlungsanlagen. Vor dem Hintergrund der europaweiten Ausschreibungspflicht wird die gegenwaertige technische Diskussion zur MBA sehr stark durch die nunmehr von der Bundesregierung konkretisierten Emissions- und Ablagerungsanforderungen gepraegt. Der vorliegende Band soll aufzeigen, welche Handlungsspielraeume sich hierbei aus Sicht der verschiedenen Bundeslaender ergeben. Ein Blick ueber die Grenzen hinaus zu einigen zukuenftigen EU

    The closer the end of coal mining in 2018, the more the issue of groundwater re-emergence in the Ruhr area is also being considered. This is especially the case because currently the subject of restitution and liability issues in the area of contaminated sites of the peaceful use of nuclear energy is discussed. In addition, the companies concerned lost considerable value on the stock market. For this reason, the question of whether the financial provisions in the created foundation are sufficient to shoulder the expected responsibilities and measures also arises with regard to coal mining. The question is which measures are to be taken and where damages can occur. Additional impulses are given by the Meggen judgment of the BVerwG of 18.12.2014, which interpreted the responsibility of the mining companies very widely. In the Rhineland, an earthquake hit 2.4 on 22.12.2015 - probably due to a rise in groundwater around the closed opencast mine Bergheim. All these questions are included in the colloquium on economics and environmental law on 26 January 2016. This also includes experiences and problems from other federal states such as Brandenburg and Saxony. [German] Je naeher das Ende des Steinkohlenbergbaus 2018 rueckt, desto eher geraet auch die Frage des Grundwasserwiederanstiegs im Ruhrgebiet ins Blickfeld. Das gilt zumal deshalb, weil aktuell ueber Rueckstellung und Haftungsfragen im Bereich der Altlasten der friedlichen Nutzung der Kernenergie diskutiert wird. Zudem verloren die betroffenen Gesellschaften an der Boerse erheblich an Wert. Daher stellt sich auch in Bezug auf den Steinkohlenbergbau die Frage, ob die finanziellen Rueckstellungen in der geschaffenen Stiftung ausreichen, um die zu erwartenden Verantwortlichkeiten und Massnahmen schultern zu koennen. Vorgelagert ist die Frage, welche Massnahmen zu ergreifen sind und wo Schaeden auftreten koennen. Zusaetzliche Impulse bekommt diese Frage durch das Meggen-Urteil des BVerwG vom 18.12.2014, welches die

    The American auto market provides an example of the conflict between government legislation calling for fuel economy and lower emissions, which can be achieved among other things by reducing vehicle weight, and other legislative initiatives on the safety front as well as the growing demands of consumers for comfort, which add weight to the vehicle. Automakers are responding by making increasing use of lightweight materials and weight-optimized vehicle concepts. Backed by years of experience with a variety of materials, The Budd Company - an American subsidiary of the Thyssen-Krupp Group - is in an excellent position to offer customized lightweight systems solutions. From conventional steel to high-strength steels, aluminum castings, sheet and extrusions through to high-quality plastics such as SMC and SRIM, lightweight solutions for auto bodies and chassis are developed and offered to the automotive industry. The lightweighting potential of these various materials is being further exploited through the use of advanced manufacturing processes, such as the hydroforming of steel and aluminum, tailored blanks made of steel, and bonding techniques for aluminum. (orig.) [German] Das Beispiel des amerikanischen Automobilmarktes zeigt die entgegengesetzten Forderungen des Gesetzgebers zur Kraftstoff- und Emissionsreduzierung, was u.a. durch eine Verringerung des Fahrzeuggewichtes zu erreichen ist, und Gesetzesinitiativen im Bereich der Fahrzeugsicherheit sowie wachsende Komfort-Ansprueche der Kunden, die zur Gewichtserhoehung fuehren, auf. Die Fahrzeughersteller reagieren hierauf mit zunehmendem Einsatz leichter Werkstoffe und gewichtsoptimierter Leichtbau-Konzepte. Im Verbund des ThyssenKrupp Konzerns ist das amerikanische Tochterunternehmen The Budd Company aufgrund ihrer jahrelangen Erfahrungen mit einer Vielzahl von Werkstoffen in der herausragenden Position, individuelle und den jeweiligen Anforderungen entsprechende Leichtbau-Systemloesungen anbieten zu koennen.

    The working group on `boindication/assessment of effects` is made up of specialists active in the fields of bioindication and emission ecology for the German Federal administrative offices concerned with the protection of the environment and for the German Environmental Protection Agency. In April 1996, this working group adopted the recommendation for a `country-wide survey on the effects of emissions using bioindicatiors`. The goal of this national survey is to determine the geographic distribution and the development over time of such emissions, as well as to document the effects of background emissions. In order to achieve these goals, the development of national measuring networks and permanent observation stations is mandatory. A minimal demand of investigations and of investigative procedures is required in order to compare the results of the individual Federal States and to consequently combine these findings as an overall picture for the entire Federal Republic of Germany. Mosses and lichens are recommended for passive biological monitoring, while standardized grass cultures, kale, stringing nettle and tobacco are suggested for active biomonitoring. In addition, detailed methodical recommendations concerning the use of standardized grass cultures and kale are discussed. (orig.)

    With the CBELASA/TAPS experiment in the framework of the SFB/TR 16 measurements of single- and double-polarization observables in the photoporoduction were performed. The energy of the high-energetic, polarized photon beams required for this, is determined by means of a so-called tagging system. In the framework of this thesis such a tagging system was constructed. It allows the energy tagging of the photons in an energy range from 0.021.E{sub 0} to 0.871.E{sub 0} with a time resolution of {sigma}=0.240 ns and an energy resolution from 0.1%.E{sub 0} to 0.4%.E{sub 0}. The reached time resolution allows to use the tagging system as time reference for the remaining experimental components. For the calculation of cross sections the knowledge of the photon flux at the experimental target is necessary. Thereby the photon definition probability P{sub {gamma}} plays a central role, which indicates, with which probability for a signal from the tagging system the corresponding photon in the {gamma} beam at the production target is present. It could be found a prescription for the determination of P{sub {gamma}}, which yields at tagging rates from 1 MHz to 10 MHz consistent results. A relative systematic error for P{sub {gamma}} was determined. Furthermore the effects of collimation and divergence of the photon beam on the number of the really in the experiment available photons and by this on the maximally reachable P{sub {gamma}} were extensively studied and experimental observations explained. [German] Mit dem CBELSA/TAPS-Experiment werden im Rahmen des SFB/TR 16 Messungen von Einfach- und Doppelpolarisationsobservablen in der Photoproduktion durchgefuehrt. Die hochenergetischen, polarisierten Photonenstrahlen werden ueber den Bremsstrahlungsprozess erzeugt. Die Energie der Photonen bestimmt sich aus der Differenz zwischen der Elektronenergie vor (E{sub 0}) und nach (E{sub e{sup -}}) dem Bremsstrahlungsprozess. Dies erfordert den Nachweis der Sekundaerelektronen mit Hilfe

    Under controlled conditions detrimental substances were applied via the shoots and roots to study the induced selective effects in the forest tree species Picea abies. Clones, single trees progenies, and provenances were employed. As toxic substances aluminium (Al) and sulphur dioxide (SO{sub 2}) were applied using hydroponics and fumigation chambers. Genetic variation was remarkable. A combined application of the substances caused a higher growth depression and induced a higher damage of the needles compared to the effects of the single stress factors. Sensitive subsets had lower genetic variation compared to the respective plants which were more tolerant. Already results of field trials indicated that high genetic variation is useful for the stability of forest tree populations. The evidents of the present study confirm this hypothesis. (orig.)

    The Directive 1999/13/EC (also called ''VOC-directive'' or ''Solvents Directive'') obliges the Member States of the European Union to a preparation of a report on the implementation of this Directive every three years. The target of a project of the Federal Environment Agency (Dessau-Rosslau, Federal Republic of Germany) is to assist the federal government in meeting the reporting requirements and to relieve the Federal States during data acquisition as possible. For this, an estimation of the CMR material types and quantities of CMR is focused. Recommendations are pronounced to determine the total emissions of VOCs from plants within the scope of the 31th BImSchV (Federal Nuisance Control Ordinance). The research project investigated the requirements for data provision in the individual Federal States and the possibilities for data delivery in addition to a full survey of the Federal States.

    Lignite samples of diffrent lithotypes and composition from opencast mines of Lusatia and the region near Leipzig were submitted to weathering processes in laboratory scale experiments and the transfer of organic matter from lignite into the hydrosphere has been observed. By means of high-performance liquid chromatography/electrospray mass spectrometry used in combination with data from gas chromatography/mass spectrometry numerous lignite-derived aromatic and heteroaromatic (poly-)carboxylic acids as well as aliphatic dicarboxylic acids could be characterized in the aqueous extracts. Investigations on water samples from lignite mining residue lakes cofirm these results. Furthermore, formation of chlororganic compounds like polychlorinated dibenzo-p-dioxine and furans (PCDD/F) and polychlorinated biphenyls (PCB), benzenes (PCBz) and phenols (PCPh) has been investigated on different lignite samples under natural weathering conditions and thermal treatment.

    (A) The problem: There is an urgent need to further develop investigation and assessment systems for the assessment of pollutant concentrations in soil and their potential effects on relevant protected assets on the basis of bioavailability. A concept for integrated effect analysis has to be developed which considers the distribution behaviour of a contaminant on the basis of its physicochemical properties and focuses especially on that fraction that may actually exert an effect. The inclusion of bioavailability is in keeping with the regulatory framework set by the Federal Soil Protection Act (BBodSchG) and the Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV). Implementation requires the development of a concept and of guidance facilitating its application in enforcement practice. (B) Need for action: Case-by-case investigations achieve their objective only partially with the methods referred to in Article 9 BBodSchG and Annex 1 BBodSchV. In particular, no suitable methods have been identified so far which consider the bioavailability of soil contaminants via all pathways. In addition, guidance on how to integrate the bioavailability of soil contaminants needs to be developed which can be used, especially by enforcement authorities, to determine the actual hazards which harmful soil changes presents to individuals and the general public. This should include a review of different combinations of approached applied in relevant legislation. (C) The purpose of the project is to compile and evaluate existing concepts for the evaluation of soil quality taking different forms of use into account. Based on this evaluation, a concept for the integration of bioavailability into soil assessment as well as a guidance document are to be developed, taking all pathways into account. The results shall be presented and discussed at an international workshop. (orig.)

Based on the fact that with many ``problem molasses`` the inhibitory effect on fermentation can be substantially reduced and often even totally eliminated by prior aeration of the hot acidic molasses solution, the chemical-analytical and biological investigations presented here focused on the components of such problem molasses volatilizable in water vapour. The water vapour distillates contain, in particular, low carbon acids (C1-C10), and alkanols (C6-C7), the minimum inhibitory concentrations (m.i.c.) of which for yeast fermentation were established. This showed very high m.i.c. levels for an inhibitory effect on fermentation, which in practice are not reached by the individual carbon acid and alkanol constituents of the problem molasses. However, these acids and alcohols exhibit marked synergic effects which were confirmed by determining the m.i.c. values of mixtures. The inhibitory effect on yeast fermentation is due above all to the presence in problem molasses of butyric acid + caprilic acid + hexanol and heptanol. (orig.) [Deutsch] Ruebenmelasse, der Hauptrohstoff fuer die Melassebrennereien und Hefefabriken, zeigt in letzter Zeit immer haeufiger nachteilige Wirkungen bei der Vergaerung sowie der Qualitaet des Produkts Backhefe. Aufgrund der Tatsache, dass sich bei vielen ``Problemmelassen`` der Gaerhemmeffekt durch vorangehende Belueftung der heiss-sauren Melasseloesung deutlich vermindern, haeufig sogar gaenzlich eliminieren laesst, wurde der Schwerpunkt der vorliegenden chemisch-analytischen und biologischen Untersuchungen auf die wasserdampffluechtigen Komponenten solcher Problemmelassen gelegt. Die Wasserdampfdestillate enthalten insbesondere niedere Carbonsaeuren (C1-C10) und Alkanole (C6-C7). Ihre minimalen Hemmkonzentrationen (MHK) bei der Hefegaerung wurden ermittelt. Dabei zeigte sich, dass im Fall der Inhibitorwirkung auf die Gaerung die MHK-Werte sehr hoch liegen; sie werden praktisch von den einzelnen Carbonsaeure- und Alkanolgehalten der Problemmelassen nicht erreicht. Jedoch weisen diese Saeuren und Alkohole deutliche Synergieeffekte auf, was durch Ermittlung der MHK-Werte von Gemischen belegt wurde. Vor allem die Gehalte der Problemmelassen an Buttersaeure + Kaprylsaeure + Hexanol und Heptanol sind fuer die Hemmwirkung bei der Hefegaerung verantwortlich. (orig.)

    This article gives an overview of the marketing options available to operators of photovoltaic and wind power plants today. These include in particular the marketing channels specified in the newly incorporated Part 3a of the 2012 Renewable Energy Law (EEG), the use of the market premium and the green electricity privilege. Under certain conditions there is also some scope today for developing marketing models outside the purview of the EEG. Within this category the article takes a look at the options of self-supply and direct supply. In this context it also describes and assesses the market integration model that was newly introduced to the EEG in August 2012 through what has come to be known as the PV Amendment.

    In 1987-1989 an emission-ground level concentration-model (conversion of emission into ground level concentration) was established for the pollutant sulphur dioxide (SO[sub 2]) by the ISP (Hannover) in cooperation with GEOS (Berlin) and was with emission data of the environs of Braunschweig for 1987 subjected to different trial runs. The pollution sources were devided into four groups: - Large Emitters (particularly power plants) - medium emitters (particularly industry) - space heating and small consumers - traffic. The pollution emitters of the first two groups were considered as point sources and the last two groups as surface sources, their emissions being evently distributed over squares of 1 km x 1 km, each surface unit of one km[sup 2] being represented by 400 point sources in a distance of 50 m from each other. The conversion of emissions into ground level concentration is based on the Gaussian dispersion model on which also the dispersion calculation of the TA Luft (technical regulation about air pollution) is based.

    The natural refrigerant carbon dioxide is gaining importance as a working fluid in compression cycles. But reliable data on flow boiling heat transfer and pressure drop were still missing. Due to that fact, a research project was carried out at the Institute of Thermal Process Engineering at the University of Karlsruhe, which was funded by the AIF and guided by the Forschungsrat Kaeltetechnik e.V. Here a short report about this investigations is given. The full report is available at the Forschungsrat Kaeltetechnik e.V. (orig.)

    Can lawyers do magic? At least some lawyers believe (even) to do. But does this work? Observers of the hearing of the German Constitutional Court trying the nuclear phase and the revision of the German Atomic Act on 15/16 March 2016 may believe it. The German Constitutional Court is trying the constitutional complaint proceedings of E.ON, RWE and Vattenfall on the legality of nuclear phase-out in Germany, essentially to the question of the compatibility of this law with the fundamental rights of the operating companies, in particular their right to property, to freedom of occupation, to equal treatment and protection of legitimate expectations.

    An ultra deep desulphurisation of less than 1 mg/kg of sulphur is necessary for the use of commercial liquid fuels in modern fuel cell systems. To reach this goal, the adsorptive desulphurisation has been chosen in scope of the current investigations. By validation of influencing parameters and by determination of optimum operation conditions a deep understanding of the current processes such as the reaction mechanism has been established. As a result the process has been improved by adding hydrogen donators as additives in liquid fuels. Furthermore it has been shown, that polar and unsaturated compounds in liquid fuels have to be avoided and aromatics have to be reduced, as all of them influence the adsorptive desulphurisation in a negative way. Despite the achieved improvements a further increase of the adsorbens capacity is necessary. Not till then the overall volume of the adsorbent is as low as required in order to integrate such processes in mobile fuel cell systems. (orig.)

    Thin chromium and aluminum films with thicknesses in the range of a few nanometers were prepared in ultra high vacuum. During film growth their dynamic conductivity was measured in-situ in the infrared regime. For an understanding of the processes determining the conductivity, the measured spectra were interpreted with the Drude and the Drude-Smith model. By this means it is possible to distinguish between different phases in the film growth. For aluminum a Vollmer-Weber-growth was found. As expected, the film thickness at the percolation transition shows a strong temperature dependence. The behaviour of chromium must be characterised as peculiar: Below a critical thickness of 2.5 nm the IR-spectra cannot be described by the Drude-model. From the measurements at different substrate temperatures, an amorphous and an island-like growth can be excluded. The presented explanation is based on a known transition from fcc clusters to the bulk bcc phase of chromium. The spectra of the nanocrystalline fcc phase can be described by a Drude-Smith type dielectric function, and the obtained parameters further back the proposed interpretation. (orig.)

    Purpose: Since feeding arteries from both the internal and external carotid artery are common, cavernous fistulas of Barrow type D are difficult to treat. Embolization using the transarterial approach is considered to be the standard therapy. However, it is often impossible to embolize feeders from the internal carotid artery. The transorbital approach after anterior orbitotomy through the ophthalmic vein is an alternative in this complex situation. The following reports our experience with three female patients who underwent transvenous embolization. Procedural success was documented using standardized MRI and clinical reevaluation. Materials and Methods: Three female patients between 57 and 78 years of age were diagnosed with carotid cavernous fistulas by conventional angiogram. All patients were suffering from exophthalmus and visual impairment. Two patients showed secondary glaucoma and diplopia. In one patient we performed a technically successful transarterial embolization using particles, but no relevant improvement of the patient's condition was seen. Transfemoral transvenous access via the sinus petrosus was not possible in any patient. All patients were then embolized via the ophthalmic vein using GDC detachable coils. All patients were clinically reevaluated by an ophthalmologist. Also a standardized MRI was performed for documentation. Follow-up was performed for the first patient for 32 months, for the second patient for 34 months and for the third patient for 50 months. Results: Transvenous embolization was technically successful in all three cases. Clinical symptoms disappeared rapidly. Postprocedural MRI showed a symmetric diameter of the ophthalmic vein. Venous congestion of the orbit caused by fatty tissue edema regressed completely. Contrast-enhanced magnetic resonance angiography showed normal arterial vessels without evidence of fistula. (orig.)

    The aim of these two projects was to determine whether platinum is contained in catalysed automobile exhaust fumes and in what quantities it is emitted. A further task was to determine the particle size and particle size distribution of emitted particles. For this purpose an engine test stand was set up at the Fraunhofer Institute for Toxicology and Aerosol Research and two different sampling techniques were developed.

    This work tries to describe the nutrient demands of six different, very fast-growing clones of the species Populus trichocarpa Torr. Et. Grey. Relevant are the capability for taking up different nutrients, and the plants' efficiency in using these nutrients for vapour exchange of the leaves (photosynthesis, respiration in the dark, transpiration) as well as for increasing biomass. A further aim pursued with these measurements is the attempt to explain the different growth of these six popular clones. Here, field experiments have shown a gradiation of the clones' growth performance. From the first to the sixth clone, growth performance declines steadily. Should there be differences among the clones as to the physiological, biometric and phenological variables to be investigated, then this work might lead to the identification of growth-determining factors suitable for postulating of the investigated clones.
