    Since April 1995, a pilot project is running in Munich for comprehensive energy management of all 1600 city-owned buildings. There will be a central facility management system which communicates with automation nodes in the individual buildings via the urban telephone network (ISDN-HICOM) or the Telekom ISDN network. In order to be independent of suppliers, an open system (FND) was chosen. Connection of about 600 buildings is envisaged as a medium-term goal. 150 buildings were connected in early 1998. [Deutsch] Seit April 1995 laeuft in Muenchen ein Pilotprojekt zum Aufbau eines umfassenden Energiemanagements fuer die rund 1600 staedtischen Gebaeude der bayerischen Metropole.

    FOVUS - Stuttgart university has put one research focus on traffic and transport. Nine faculties are involved in this task, whose first project is organised in conjunction with the city of Stuttgart and will start in spring 2000. Scientific monitoring and support of the building of a network of more than 80 municipalities in Latin America and Europe is both a challenge and a sign that things are heading in the right direction (for more details see the contribution entitled ''European-Latin American network: how to control urban mobility''). Another comprehensive research project started by the FOVUS institutes is called ''Linking traffic and transport - integration of models, information, people, rail and road''. The main subject of this ''Uni-Kurier'' is a follow-up of the last edition (No. 82/83)- which dealt with the basic features of town planning and -development, regional planning and ecology - and looks at newer and more technical aspects of traffic and transport. This edition also deals with the following issues: cars and infrastructure, traffic models and control, evaluation and assessment of the social, ecological and economical impact of traffic and transport.(orig.).

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

    The CRESST-II experiment for the direct detection of WIMP dark matter uses scintillating CaWO{sub 4} crystals that are operated as low-temperature detectors. EURECA is a joint collaboration of existing cryogenic direct dark matter searches to develop a future multi-material experiment with a target mass of up to one ton. While in the past crystals were obtained from external suppliers, we recently started producing CaWO{sub 4} single crystals with a dedicated Czochralski furnace at the Technische Universitaet Muenchen to have a direct influence on the radiopurity and scintillation properties. We present here an overview of the growth process as well as measurements of the crystals' scintillation properties and radiopurity.

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

    During the summer term 2010 several theses on the topic of infrastructural development of the village Yuwentsa situated in the Ecuadorian rainforest were written at the Technische Universitaet Muenchen. One of these works was especially concerned with the electrical energy supply of the community and a planned rainforest academy by micro hydro power. Within this study a major task was to identify appropriate installation sites and to develop practicable structural measures. Finally two sites were investigated, one for the installation of a water wheel and another for the construction of a power plant using a conventional turbine with penstock. A special challenge was the lack of hydrological data which made it necessary to put more effort on flood prevention. Another central issue of the two-week stay at the village was the knowledge exchange and cooperation between the students and the indigenas. (orig.)

    2015-07-01

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

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

    A survey is given of the broad range of technical applications of surfactants. By means of some examples it is pointed out how basic properties of surfactants (spreading, emulsifying, dispersing, foaming, clouding) can advantageously be used to develop application-possibilities for the use in the field of `non-detergents`. The application of ether carboxylic acids and end group blocked ethoxylates are discussed as examples for the solution of problems in the field of metal working and textile processing. (orig.)

    Full Text Available Beim VD 16, 17 und 18 handelt es sich um drei retrospektive Nationalbibliographien des 16., 17. und 18. Jahrhunderts. Angelegt wurden die drei Verzeichnisse der im deutschen Sprachraum/Sprachbereich erschienenen Drucke zeitlich versetzt zueinander. Die gesamte Entstehungsspanne reicht dabei mittlerweile über 50 Jahre. Dass es im Laufe der Zeit zu methodischen Verschiebungen gekommen ist, erstaunt deshalb wenig. Dieser Artikel konzentriert sich gezielt auf Veränderungen, die sich durch technische Entwicklungen für den Charakter der VDs ergeben haben. Als wesentliche technische Einflussgrößen lassen sich Verzeichnisformate und Digitalisierungsmöglichkeiten beschreiben. Folgen und Chancen ergeben sich daraus vor allem für vier Bereiche: Funktionen, Erschließungsstandards und Vollständigkeit der VDs sowie die Zugriffsmöglichkeiten auf ihre Daten.

    The cooling capacity of the air conditioning system of this fully glazed, representative exhibition pavillong was increased. The auxiliary system was to meet a number of boundary conditions, e.g. conservation of a historical building, integration of the new components in the existing building, thermal comfort, optical attractivity. In order to ensure high thermal efficiency, compact size and energy conservation, a VRV inverter system was chosen. The fundamentals of dimensioning, the boundary conditions on the building side, and the technical systems are described, and preliminary operating experience is presented. (orig.)

    The author describes the retrospective data acquisition and evaluation on the characterization and prognosis for 776 patients (average age 40:1 years) with differentiated thyroid carcinomas in the Klinik und Poliklinik fuer Nuklearmedizin der Universitaet zu Koeln in the period from 1990 to 2005. The methodology includes patient-relevant data, examination data, imaging techniques and biochemical tests. Clinically important differences were found for papillary and follicular thyroid carcinoma. Further differences concern the localization of metastases. The author discusses the prognostic significance of the primary tumor radius in comparison with the so-called TNM classification for papillary and follicular thyroid carcinomas. It is concluded that the new version of the TNM classification offers only slight advantages with respect to the former version. It was also shown that the primary tumor size is adequate for prognostic estimations.

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

    Due to the current liberalization process the European gas business is changing rapidly. Many new problems that arise will have to be solved by practical solutions. Especially the German gas business with its very heterogeneous structure is already facing a lot of difficulties, which may also become apparent on a European level with further liberalization progress. An example is the handling of transportation for household customers on the basis of load profiles. The second amendment of the German gas association agreement encompasses technical guidelines for network access, which encompass solutions for some of the arising problems. It becomes evident that the technical guidelines are equivalent to a functional standard for third party access in the German gas market. (orig.) [German] Die europaeische Gaswirtschaft befindet sich, verursacht durch die Liberalisierung der Energiemaerkte, in einer rasanten Umbruchphase. Fuer viele neue Probleme muessen angemessene Loesungen gefunden werden; die deutsche Gaswirtschaft sieht sich wegen ihrer mehrstufigen Struktur bereits auf natioanler Ebene mit vielen Fragestellungen konfrontiert, die sich in naechster Zeit auch auf internationaler Ebene einstellen werden. Ein Beispiel hierfuer ist die Abwicklung von Gastransporten zur Belieferung nicht leistungsgemessener Kunden mittels Lastprofilen. Im Rahmen des zweiten Nachtrags zur VV Gas sind technische Rahmenbedingungen fuer den Netzzugang abgestimmt, die fuer einige dieser Probleme Loesungen darstellen.

    Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes. We have recently analyzed data concerning the decay rates of Cl-36 and Si-32, acquired at the Brookhaven National Laboratory (BNL), to search for evidence that might be indicative of a process involving solar rotation. Smoothing of the power spectrum by weighted-running-mean analysis leads to a significant peak at frequency 11.18/yr, which is lower than the equatorial synodic rotation rates of the convection and radiative zones. This article concerns measurements of the decay rates of Ra-226 acquired at the Physikalisch-Technische Bundesanstalt (PTB) in Germany. We find that a similar (but not identical) analysis yields a significant peak in the PTB dataset at frequency 11.21/yr, and a peak in the BNL dataset at 11.25/yr. The change in the BNL result is not significant since the uncertainties in the BNL and PTB analyses are estimated to be 0.13/yr and 0....

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

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

    Following up on the PAMELA collaboration's detection of trapped antiprotons in low-Earth orbit, the Technische Universitaet Muenchen has founded a student-developed endeavor to measure the yet-unknown low-energy antiproton flux in the Van Allen belt. The satellite-borne experiment will consist of a cube of scintillating fibers, and will discern antiprotons by detecting the pions of their characteristic annihilation. We have built a 128-channel prototype detector to test the ability to measure low-energy particles with scintillating fibers and Geiger-mode avalanche photodiodes (G-APD). After testing several different fiber types and APD-fiber coupling methods, we built the prototype with aluminum-wrapped Kuraray fibers. Additionly we have compared and contrasted KETEK and Hamamatsu G-APDs, studying in particular their dark count rates, cross talk intensities, photo-detection efficiencies, temperature dependences, and gains. I present our findings as well as an introduction to the experiment's aims and schematic structure.

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

    Computed tomography (CT) is a three-dimensional (3D) imaging method which, for compact or prolate (i.e. rather isotropically extended around the rotation axis) specimens, can yield artefact-free reconstructed cross-sections. Laterally extended specimens like plate-like objects, however, are much less amenable to CT since reliable projection data cannot be acquired from angles where the plate is oriented parallel to the irradiation direction. To overcome this drawback, computed laminography (CL) was introduced recently to imaging set-ups at synchrotron storage rings. Here, we report on the first implementation of computed laminography with neutron radiation, showing measurements that were performed at the ANTARES neutron imaging facility at the FRM II research reactor of Technische Universitaet Muenchen. In general, neutrons are highly interesting probes for imaging since they provide a sensitivity to chemical elements very different from X-rays, yielding complementary information about the specimens investigated. Like for X-ray laminography, we avoid the projection directions where the beam is parallel to the long extensions of the specimen. We accomplish this by tilting of the rotation axis with respect to the transmitted-beam to an angle smaller than 90{sup o} (which would be the limiting case of CT) and roughly aligning the specimen's surface normal parallel to this rotation axis. The principles of neutron laminography are introduced and first test experiments are described.

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

    Modern experiments permanently improve the precision of parameters in nuclear and particle physics. Besides high-performance detectors, state-of-the-art readout electronics and recent data acquisition systems contribute substantially to the increasingly better accuracy. This talk therefore presents the readout system, which is being designed for the neutron lifetime experiment PENeLOPE, currently under construction at Technische Universitaet Muenchen. The system*s readout chain involves preamplifier, shaper, sampling ADC, and a data processing stage implemented on field programmable gate arrays (FPGAs). The FPGAs perform the task of online data analysis and formatting and are able to transfer data to a computer via a high-speed Ethernet connection. An advanced algorithm enables them to calculate the pedestal for every single channel online, and to reliably detect all signals above noise. Due to this incorporated signal detection, the triggerless system is able to process and to format pulse shapes from around 1,000 channels simultaneously, each of which is hit by 10 particles/sec. This corresponds to a data rate of 1.5 MB/sec, which is read out to a computer where the pulse shapes are available for further analysis. In the talk, performance and first tests of this readout system are presented in detail.

    The aim of PENeLOPE is a high-precision measurement of the neutron lifetime and thereby an increase of the parameter's precision by one order of magnitude. In order to achieve an increasingly higher accuracy, modern experiments naturally require state-of-the-art readout electronics, as well as high-performance data acquisition systems. This talk therefore presents the readout system for the neutron lifetime experiment PENeLOPE, which is currently being designed at the department of physics at Technische Universitaet Muenchen. The system's readout chain involves preamplifier, shaper, sampling ADC, and a data processing stage implemented on field programmable gate arrays (FPGAs). Due to the incorporated signal detection, the system is able to process data from 1,000 self-triggering channels, each of which is hit by 10 particles/sec. The corresponding data rate of 1.5 MB/sec is transferred to the outside of the experiment by a high-speed optical interface, which has been developed to meet the special experimental requirements of PENeLOPE. The main focus of the talk is set on the performance and tests of the trigger algorithm as well as on characteristics and properties of the optical interface.

    A qualitative and a quantitative study on the title subject were carried out. The quantitative study is based on the third measurement of the multi-client study in which attention is paid to attitudes (and use) of energy en the interest for domotica. The results are correlated with different types of communities. In the qualitative study attention is paid to motives to purchase domotica applications. [Dutch] Het programma DEMOS heeft in 2001 een aantal strategische studies uitgezet die elk een aspect van domotica en technische gedragsturing nader analyseren. In deze studie wordt specifiek gekeken naar de attitude van verschillende deelsegmenten consumenten inzake energie en de potentieale interesse voor domotica en technische gedragsturing, teneinde energiebesparing te realiseren. Motivaction heeft de studie, die bestaat uit een kwantitatieve en kwalitatieve fase, uitgevoerd.

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

  19. Development of a system for neutron radiography and tomography

    Mühlbauer, Martin J.; Calzada, Elbio; Schillinger, Burkhard

    2005-04-01

    Neutron radiography and tomography are getting more and more popular. Since they use the white thermal neutron spectrum, they are especially feasible even at small neutron sources, where the flux is too low for efficient scattering experiments requiring monochromatization of the beam. High-end tomography systems require the investment of several ten thousand Euros, with the costs often hindering the initiative for a new tomography setup. Based on the experiences gathered at Technische Universitaet Muenchen, we developed a cheaper system based on standard components that cannot compete with the sensitivity of a high-grade system, but is perfectly capable of doing neutron radiography and tomography. The system is meant as a startup construction kit for initiating tomography programs even at small neutron sources. The system is built from scratch, enabling the user to gain an understanding for the influence of each component on the image results. With the experience thus gained, he should be able to design his next and more advanced system by himself. To keep the whole system simple and cheap (the price should reach only a few percent of a high-end system), standard parts are used whenever possible, and all components are designed in such a way that they can be built without special equipment. Public domain and freeware software is used for data processing. Such a system is being built at FRM2 in Garching within the scope of a master thesis. After completion, a website will be installed with descriptions, diagrams and software for building and operating the system. Both hardware and software are discussed.

    Abstract Several retrospective analyses on patients who underwent gastric cancer (GC) surgery revealed different survival outcomes between Eastern (Korean, Japanese) and Western (USA, Europe) countries due to potential ethnical and biological differences. This study investigates treatment outcomes between specialized institution for GC in Korea and Germany. The prospectively documented databases of the Gastric Cancer Center of the National Cancer Center, Korea (NCCK) and the Department of Surgery of the Technische Universitaet Muenchen (TUM), Germany were screened for patients who underwent primary surgical resection for GC between 2002 and 2008. Baseline characteristics were compared using χ2 testing, and 2 cohorts were matched using a propensity score matching (PSM) method. Patients’ survival was estimated using Kaplan–Meier method, and multivariable Cox proportional hazard model was used for comparison. Three thousand seven hundred ninety-five patients were included in the final analysis, 3542 from Korea and 253 from Germany. Baseline characteristics revealed statistically significant differences for age, tumor location, pT stage, grading, lymphatic vessel infiltration (LVI), comorbidities, number of dissected lymph nodes (LN), postoperative complications, lymph-node ratio stage, and application of adjuvant chemotherapy. After PSM, 171 patients in TUM were matched to NCCK patients, and baseline characteristics for both cohorts were well balanced. Patients in Korea had significantly longer survival than those in Germany both before and after PSM. When the analysis was performed for each UICC stage separately, same trend was found over all UICC stages before PSM. However, significant difference in survival was observed only for UICC I after PSM. This analysis demonstrates different survival outcomes after surgical treatment of GC on different continents in specialized centers after balancing of baseline characteristics by PSM. PMID:27428238

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

    For years, the so-called new actuators, the ``muscles of microelectronics``, have been gaining in importance in all fields of technology. Actuators consist of functional elements, i.e. power amplifiers, energy transducer, and gearings. They convert electrical energy into mechanical energy and switch, control or regulate technical processes. The use of new or multifunctional materials such as piezoelectric low-voltage PZT ceramics and electrorheological and magnetorheological fluids (ERF and MRF) has added many new types to the existing conventional ones. Numerous improved and new microsystems, mechatronics and adaptronics products will depend on the performance, i.e. forces, travel, actuating time, energy density, and unit volumes, of new actuators. There will be an increasing demand for multifunctional properties such as simultaneous sensor and actuator operation. This manual gives a comprehensive survey of the state of the art, the state of science, and of developments. It discusses the design of new actuators, the corresponding production technologies, the performance of actuators, and future trends. 18 sections are dedicated to the mechanical design of actuators, to actuator travel modifications, electronic triggering, and to technology and market potentials. Selected practical examples reveal the great application and product potentials of new actuators and facilitate access to design solutions. (orig.). 309 figs., 35 tabs., 412 refs.

    Kossert and Nahle of the Physikalisch-Technische Bundesanstalt (PTB) have recently studied measurements from their beta-decay experiment that registers triple coincidences in a TDCR (Triple-to-Double Coincidence Ratio) system. Our analysis of the PTB data reveals evidence (which is a function of solar elevation) of an oscillation at 11 year-1, which we interpret as an influence of internal solar rotation. For comparison, we have analyzed radon beta-decay data for exactly the same time interval acquired at the Geological Survey of Israel (GSI). This analysis yields strong confirmation of the 11 year-1 rotational signal and of its dependence on solar elevation. These results are compatible with the proposition that beta decays may be stimulated by solar neutrinos.

    The new research reactor FRM II is a high-performance neutron source. A new gamma irradiation line for high-intensity gamma radiation is planned in spent fuel elements including a heating system that will allow irradiation at temperatures up to 150 C. The design concept considers the experimental boundary conditions, i.e. irradiation inhomogeneity and sample temperatures, but also the spent fuel element safety. The neutron flux was measured in two spent fuel elements with decay times of 90 and 450 days, respectively. A significant neutron activation of the irradiation samples can be excluded. The dose rate profile in the spent fuel element was measured with a special measuring device. The irradiation facility will be started in 2009. An first research program concerning microstructure investigations of gamma irradiated rock salt is described.

    Within the framework of the project 'Fresh Schools' the NL Agency has set up a program of technical requirements for schools of primary and secondary education, where requirements for energy efficiency and indoor environment in the categories A (very good), B (good) en C (acceptable) were developed. In new construction projects basically the minimum performance requirements of category B is recommended. This article is based on a computational study at a primary school to see what the consequences are of this program of requirements (category B), with respect to the choice of the climate installation concept, the need for cooling, the energy performance and the necessary installation costs. [Dutch] Agentschap NL heeft in het kadervan het project 'Frisse Scholen' een technisch Programma van Eisen ontwikkeld voor scholen voor het basisonderwijs en het voortgezet onderwijs.

Bij nieuwbouwprojecten gelden in principe minimaal de prestatie-eisen volgens klasse B. Een rekenstudie aan een basisschool laat zien wat de consequenties van dit Programma van Eisen (klasse B) zijn voor de keuze en het ontwerp van de klimaatinstallatie, de noodzaak van koeling, de energieprestatie en het benodigde budget voor de installaties.

  8. Neutron μstiX. Micrometer structure investigation with real space and reciprocal space crossover using neutron imaging detectors

    2013-07-19

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

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

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

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

    In order to reduce the PM{sub 10} concentrations in the ambient air in Munich, Germany two measures have been introduced in 2008. In February 2008 the law forbidding transit of vehicles heavier than 3.5 tons through the city area took effect. Additionally, a low emission zone was established in the inner city of Munich in October 2008. In our analysis we study the impact of those measures on the ambient PM{sub 10} concentrations by comparing two 4 months periods, the first one before the measures became operative and the second one after it. By means of a reference station located in a background area we adjusted our analysis on the influence of the meteorological conditions. A reduction of the relative PM{sub 10} burden was observed and the magnitude of the decrease was in line with the results calculated by modelling. The decrease was small and especially pronounced at traffic sites. Due to the kind of measures it is obvious that the reduced fraction of PM{sub 10} was mostly generated by traffic (and especially diesel engines), which is known to be especially relevant for human health.

    Technische Universität Darmstadt is a famous German technical university whose graduates are preferred by German enterprises. Its training program was analyzed in this paper to show the positive alternate action of university and enterprise on the self-development of the students. Then three suggestions were made for the Chinese higher education of engineering. The first is to let the enterprises participate more in the higher educa-tion by making new rules;the second is to employ different levels of teachers who have more industrial experiences;the third is to avoid the habit that teachers are busy with students' duty and the students obey only.%德国达姆斯塔特工业大学是一所毕业生深受德国企业界欢迎的著名大学。文章通过分析其机械系的培养方案展示了大学与企业交替性发挥作用帮助学生通过自主性学习走向独立工作的过程,给正在改革的中国工程教育提出了几点改善学生自我塑造环境的建议:一是通过建立制度让企业更多地参与;二是聘用具有更多企业经历的、多层次的高校教师;三是要避免教师代替学生忙碌的现象。

    1980-06-01

    The objective of this paper is to propose an approach in production economics which incroporates the aspect of substitutability in the neoclassical theory as well as the aspect of partially fixed factor proportions in the Walras-Leontief approach. The crucial idea is to decompose the input quantity in a component bound by the use of other inputs and in a component unbound or free for substitution. From the cost side this partitioning implies that the effective price of a factor consists of the own price as well as of weighted prices of the other inputs with weights indicating which inputs are bound in which order of magnitude to the use of a unit of the corresponding factor of production.

    The torrefaction process is a thermal treatment of raw biomass during the absence of oxygen at a temperature range between 200 to 300 C and at a residence time of 15 to 90 minutes under atmospheric pressure. Here, the released water and low calorific volatile components reduce the mass by approximately 30 % while the energy content of torrefied biomass decreases by about 10 %. Compared to raw biomass, torrefied biomass is easier to grind and has a high energy density similar to coal. The Institute for Energy Systems and Technology (EST) at the Technische Universitaet Darmstadt is currently researching the torrefaction process of biomass. The proposed model will be validated towards the measurements in the frame of a CFD simulation program. (orig.)

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

    Full Text Available Bei der instrumentellen Therapie der benignen Prostatahyperplasie wird eine hohe Gewebeabtragerate bei geringer Blutungsrate angestrebt. Mit den bisher verfügbaren Hochfrequenzstromelektroden mußte jedoch entweder eine hohe Blutungsrate (Standardschlinge oder eine stark reduzierte Gewebeablation (Elektrovaporisation in Kauf genommen werden. Zur Optimierung der TUR-P wurde Rotoresect entwickelt. Rotoresect besteht aus einem speziellen Arbeitselement, bei dem eine Gewebefräskopfelektrode durch einen Mikromotor aktiv angetrieben wird. Im Anschluß an eine Phase 1-Studie mit 20 Patienten wurde in einer Phase 2-Studie an 20 Patienten eine transurethrale Rotoresektion der Prostata durchgeführt. Das durchschnittliche Prostatavolumen (TRUS betrug 44,0 ± 15,4 ml. Die rotierende Gewebefräskopfelektrode ermöglicht eine Gewebekoagulation, -vaporisation und eine zusätzliche mechanische Ablation. Während der Resektion konnten keine signifikanten Blutungen beobachtet werden. Daraus resultierend konnten keine signifikanten Änderungen von prä- und postoperativer Hämoglobin- (1,0 ± 0,8 g/dl sowie Natriumkonzentration (2,6 ± 3,1 mmol/l festgestellt werden. Die postoperative Katheterzeit betrug durchschnittlich 1,5 ± 1 Tage. Der Uroflow konnte von durchschnittlich 9,1 ± 3,4 auf 22,0 ± 6,33 ml/sec. gesteigert, der Restharn von durchschnittlich 170,9 ± 117,7 auf 29,1 ± 17,6 ml gesenkt, der IPSS um durchschnittlich 17 Punkte (22,0 ± 8,5 auf 4,9 ± 2,9 und der Quality of life-Index um durchschnittlich 3 Punkte (4,2 ± 3,1 auf 0,9 ± 0,8 gesenkt werden.

    In contrast to positron emission tomography/computed tomography (PET/CT), the currently available single photon emission computed tomography/computed tomography (SPECT/CT) systems are very heterogeneous. On the side of the gamma cameras, dual-head systems are established, which are not very different from one manufacturer to the other. For the CT component, there are low dose tubes on the one side and flat detector-based cone beam CT and multislice-CT on the other. The CT image data can be used for anatomic correlation of suspicious findings as well as for attenuation correction of SPECT data. Attenuation correction enables on the one hand enhancement of SPECT image quality and on the other hand quantification of the radioactivity concentration becomes possible. Modern iterative reconstruction algorithms allow scatter correction and attenuation correction of SPECT data using the density values from CT. It still has to be shown to what extent attenuation-corrected whole body SPECT/CT studies will be able to improve the sensitivity of scintigraphy studies. As SPECT/CT primarily aims at morphologic correlation and not detection of additional lesions, an attempt should be made to balance the necessary anatomic information and the additional radiation exposure. Besides SPECT-guided CT all technical possibilities for dose reduction should be exhausted. (orig.) [German] Im Gegensatz zur Positronenemissionstomographie/Computertomographie (PET/CT) sind die auf dem Markt angebotenen Single-photon-emission-computed-tomography/CT(SPECT/CT)-Systeme sehr heterogen. Auf der Seite der Gammakameras sind Zweikopfsysteme etabliert, die sich bei den verschiedenen Wettbewerbern nur unwesentlich unterscheiden. Hingegen reicht bei der CT-Komponente die Palette von der einfachen Niedrigdosisroentgenroehre ueber die flachdetektorbasierte Cone-beam-CT-Technologie bis hin zum Mehrzeilenspiral-CT. Die CT-Bilddaten werden dabei zum einen zur anatomischen Korrelation funktionell auffaelliger Befunde verwendet, koennen aber auch fuer eine Schwaechungskorrektur der SPECT-Daten herangezogen werden. Neben einer qualitativen Verbesserung der SPECT-Bilder eroeffnet sich damit nunmehr die Moeglichkeit der Quantifizierung der Radioaktivitaetskonzentration. Moderne iterative Rekonstruktionsalgorithmen erlauben unter Verwendung der Dichteinformation aus den CT-Daten eine Streu- und Schwaechungskorrektur der SPECT-Daten. Inwiefern sich die Sensitivitaet szintigraphischer Untersuchungen durch den Einsatz schwaechungskorrigierter Ganzkoerper-SPECT/CT-Aufnahmen erhoehen laesst, muss erst in entsprechenden Studien gezeigt werden. Da bei der SPECT/CT nicht das Auffinden zusaetzlicher Radionuklidspeicherungen, sondern die morphologische und damit verbunden die artdiagnostische Zuordnung das primaere Ziel darstellt, sollte auf die Ausgewogenheit notwendiger morphologischer Information und erforderlicher zusaetzlicher Strahlenexposition geachtet werden. Neben der SPECT-gefuehrten CT sollten auch alle technischen Moeglichkeiten der Dosisreduktion ausgeschoepft werden. (orig.)

    How different land uses change CO2-fluxes under similar climatic conditions is a core question concerning the estimation of carbon sinks. Here, the TUD-cluster forms an excellent basis since it provides long-term measurements of Eddy-Covariance fluxes for different land uses. Measurements started at the Anchor Station Tharandter Wald (Spruce) in 1996. Since then the TUD-cluster has been successively complemented by continuous greenhouse gas flux observatories at Grillenburg (grassland), Klingenberg (crop rotation) and Spreewald (wetland), which have been operated since 2002, 2004 and 2010. The results of the TUD-cluster have been shared internationally in research frameworks such as EUROFLUX and subsequent research frameworks and is now part of ICOS-D (Integrated Carbon Observation System), the German branch to ICOS Europe. This contribution focuses on the presentation of the different sites with comparatively similar climatic conditions but different CO2-fluxes, water fluxes and energy fluxes. Influences of management and climatic conditions will be shown which are apparent in long-term data as well as interesting aspects of distinct land uses.

    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.

    The production of wood based fuels such as wooden logs, wood chip, wooden briquettes or pellets has become standard practice. The easy handling of wood as an energy source has contributed to its popularity. A growing demand for wood based fuels has resulted in higher prices and the increasing demand is being met more and more by imports. The florafuel-Procedure provides an alternative to this trend by processing stalks and biomass waste, which in turn means a considerably broader raw material base. The procedure, which produces fuel in the form of pellets or briquettes to generate electricity or heat, is currently being optimised at the University of the German Federal Armed Forces in Munich (Universitaet der Bundeswehr Muenchen) and is about to complete a demonstration plant which should prove its economic viability. Substances such as chlorine and potassium which normally cause concern during the combustion of stalks and stems can be significantly reduced through this production process. Moreover, the materials used as an energy source do not compete with food production. The fuel produced can be easily transported and stored. It can be used to meet both base load and peak load demands and has therefore proven to be highly flexible. Easy handling, little storage space and low capital expenditure are important characteristics of the florafuel-Procedure. Compared to other production processes, the florafuel-Procedure shows a very favourable energy balance for biomass based on stalks and stems. (orig.)

    The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil. The Hydrology Department of Brandenburgische Technische Universitaet Cottbus, on behalf of the Thuringian Environmental Authority, investigated the state of the art of discharge of precipitated water into natural soils. The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection. [German] Die Nutzung natuerlicher Boeden zur kostenguenstigen Beseitigung von Niederschlagswasser aber auch von schwachbelastetem Abwasser ist eine Variante der Abwasserbeseitigung, die zunehmend Antragsgegenstand in wasserrechtlichen Verfahren ist.

    Hydrothermal Carbonization (HTC) is a process which converts biomass of vegetal origin into a material comparable to brown coal. The HTC process is performed with biomass suspensions in a pressure vessel under temperatures of 180-250 C and just needs some hours. Starting with an overview of the present state of knowledge about HTC reactions the paper presents the results of a research project funded by the DBU (Deutsche Bundesstiftung Umwelt) which has shown the suitability of the HTC-process for a broad spectrum of organic municipal wastes. In particular wastes and residues of high water content are predestined for conversion via HTC. HTC-Biocoals show a high calorific value and can be energetically utilised accordingly. A basic advantage is seen in the excellent dewatering properties of these biocoals. Reaction temperature, reaction time and process management can determine yield and properties of HTC-Biocoals to a certain degree. Practical implementation of HTC has to consider aspects like utilisation of the exothermic nature of the process, process water treatment and concentration of contaminants in different HTC-product phases.

    Self-excited rotor whirl represents a serious hazard in the operation of turbomachines. The reported investigation has, therefore, the objective to measure the lateral forces acting on the rotor and to determine the characteristic pressure distribution in the rotor clearance area. A description is presented of an approach for calculating the leakage flow in the case of an eccentric rotor position on the basis of empirical loss coefficients. The results are reported of an experimental investigation with a turbine stage, taking into account a variation of the clearance characteristics. The pressure data measured are consistent with the theoretical considerations.

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

    Currently decentralized electrical generation units (DG units) are connected to the network in Europe with an increasing number and generation capacity. Currently the operator of a DG unit or the availability of fluctuation primary energy determines the power and time of the generation fed into the grid. The distribution system operator (DSO) is blind'' towards the current power of the DG units in his grid because of the lack of observability and controllability of these generators in the low voltage level. Therefore a new strategy for the integration of DG units into grid operation will be required. This strategy will include energy management with controllable generators as well as controllable loads. In the concept developed in the project DINAR the point of common coupling (PCC), which acts as the technical as well as legal interface between grid operator on the one side and operator of the generator on the other side, will be extended by a communication interface. This allows a technically efficient design of an energy management system and avoids fundamental organizational changes to the current grid regime. The design of such a bidirectional energy management interface as a new implementation of the PCC is also presented within the article. (orig.)

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

    In the future, the price pressure and cost pressure clearly will strengthen in the case of photovoltaic. On the one hand, this is due to an intensified degression which is intended in the context of the novella of the Renewable Energy Resources Act. On the other hand, the competition clearly will intensify with increasing availability of silicon. In this background, the technological development must be further accelerated energetically by research activities of enterprises just by the application oriented research promotion of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (Dessau, Federal Republic of Germany) and the fundamental oriented promotion of the Federal Ministry of Education and Research (Berlin, Federal Republic of Germany). Germany is set up excellently according to the launching instruments on the one hand and in national comparison on the other hand.

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

    Essent Netwerk Noord has decided to adopt a radically different approach for maintenance and new construction of its power grids. The grid company is now trying to analyse the risks it runs before actually starting a project. Since all risks are known simultaneously, the grid company is able to select those projects yielding the greatest risk reduction per euro. [Dutch] Essent Netwerk Noord heeft het onderhoud en de nieuwbouw van zijn netten over een radicaal andere boeg gegooid. Het netwerkbedrijf probeert nu eerst te achterhalen welke risico's het loopt alvorens een project te starten. Omdat alle risico's tegelijkertijd bekend zijn, kan het netwerkbedrijf die projecten selecteren die de grootste risicoreductie per euro opleveren. Daarvoor moet het management wel eerst aangeven welke risico's aanvaardbaar zijn, terwijl ook een forse investering in informatietechnologie nodig is.

    The conception and implementation of a diagnostic system and its preliminary results are described. The system was to improve the operation of the heating power station of TU Munich university in terms of higher availability. Simulations and online trial operation were successful. A multitude of errors were detected which were uncritical as a rule but which might have led to standstill or damage in certain conditions. The hkwdiag system enabled to operators to react early and take prefentive measures. Although hkwdiag cannot prevent spontaneous errors with direct effects, it may be a supportive tool in the subsequent phase in which a stable state of operation must be achieved again in order to prevent secondary damage. (orig.) [German] Mit dem Projekt hkwdiag wurden die Konzeption und die Implementierung eines Diagnosesystems sowie erste Erfahrungen mit dessen Betrieb vorgestellt. Intention war es, im speziellen die Betriebssituation im Heizkraftwerk der Technischen Universitaet Muenchen zu verbessern und im allgemeinen Hinweise zu erarbeiten, inwieweit Diagnosesysteme einen Beitrag zur Erhoehung der Verfuegbarkeit leisten koennen. Sowohl bei Tests mit aufgezeichneten Daten, die es erlaubten, einen Zeitraum von ca. 3 Jahren zu simulieren, als auch im online-Betrieb ueber mehrere Monate hinweg konnte hkwdiag mit allen Modulen seine Zuverlaessigkeit und Robustheit unter Beweis stellen. Waehrend des Einsatzes wurde eine Vielzahl von Fehlern gemeldet, die zwar meistens unkritischen Charakter besassen, aber unter bestimmten Umstaenden sehr schnell zum Anlagenausfall oder zu einem Schaden haetten fuehren koennen. Hier hat hkwdiag die Chance eroeffnet, fruehzeitig und praeventiv zu reagieren. Spontan auftretende Fehler mit direkten Auswirkungen kann das Diagnosesystem im allgemeinen nicht verhindern. Allerdings kann es die anschliessende Phase, bei der die Anlage in einen sicheren Zustand ueberfuehrt werden muss, unterstuetzend und beratend begleiten, so dass Folgefehler

TLS is clinically characterized by acute renal failure, hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. While limited options are available for treating TLS, identifying patients at high risk for developing TLS and prevention in high-risk patients remain an important aspect in the treatment of cancer patients. In general, treatment of TLS consists of intensive hydration, stimulation of diuresis, and, more specifically, in the use of allopurinol and rasburicase. Rasburicase, a recombinant urate oxidase, rapidly and effectively reduces hyperuricemia, which subsequently significantly decreases the risk of acute renal failure and other clinical manifestations of TLS. For this review, a comprehensive literature search using the term “tumor lysis syndrome” and/or “rasburicase” was performed considering articles listed in MEDLINE. Incidence, prevention, and therapy of TLS with a special focus on the role of rasburicase are discussed. We evaluated 120 relevant articles including 35 case reports, 32 clinical trials, and 14 meta-analyses. Keywords: rasburicase, tumor lysis syndrome, hyperuricemia, acute kidney injury

    As there is no difference in biological response between natural and artificial radiation, regulations should cover both, but this seems to be a 'shaking of the coconut tree'. It would amount to the evacuation of large populated areas, the end of important non-nuclear industries - or the politically not correct upward adjustment of the current 1 mSv/y limit towards the substantial fluctuations in the natural exposure by a factor of 10 and more. During a large international conference in Munich in September, and a smaller follow-up symposium in Dresden, scientists from about forty countries discussed the science and the politics in establishing the present double standards. There were, for example, reports about basic differences in the biological effects of low and high doses; results showing that it is the dose-rate, not the dose, which matters; consistent reports about the lack of detrimental health effects in high natural radiation areas (>10 mSv/y) in China, India, etc.; and the usual controversies about the value and limits of radon epidemiology - all contributing to serious questions about various basic contradictions and uncertainties in the self-inflicted ghetto situation of current radiation protection.

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

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

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

    55% of all roads at RAG are driven by drilling and blasting operations. The Ibbenbueren mine is an exception, because 100 % of all roads are driven by drilling and blasting operations. The combined support type A has been adopted to an increasing extent in support technology in the last ten years. The Ibbenbueren mine is also a pioneer in this respect because the first drivage with Combi support type A was undertaken 25 years ago and in addition to exclusively bolted supports Combi support type A is currently introduced for 95 % of the supports. The standardised drivage and support system at the Ibbenbueren mine is described, optimisation potentials in the blasting operations, but also in bolting technology by means of the Lean Processing Improvement programme being indicated.

    The gas cavern storage facility in Empelde came into operation with three caverns between the early and the middle nineteen-eighties and is subject to a surface and subsurface extension since 2004. The subsurface extension comprises the construction of two new caverns (K4 is operated since 2009, K5 in leaching process since 2010) and the leaching extension as well as repair works of both existing caverns K2 (since 2012 in gas operation again) and K1 (is being re-leached since the end of 2012). The volumetric extension process of cavern K2 took place in three steps: flooding, releaching, gas re-filling. The flooding with water through a 4 1/2'' tubing were implemented discontinuously alternating with phases of gas withdrawal through the annulus 4 1/2'' x 9 5/8'' in order to minimize the risk of hydrate formation. The length of the individual phases mainly depended on the gas demand/consumption of the storage users. Water injection has been made in a gas well-head pressure range above the hydrostatic pressure of the water column in order to keep it stable at any time and to keep the cavern pressure high. The cavern volume increased by 12% because of the flooding. For the re-leaching process the existing 9 5/8'' tubing was pulled out and the permanent packer was milled. By using leaching strings 6 5/8'' x 10 3/4'' a maximum leaching rate of 300 m{sup 3}/h was realized and within 10 months an additional volume of 212,500 m{sup 3} was created according to the evaluation of the leaching process. Due to the geological affected development of the cavern shape the 6 5/8'' leaching string had to be pulled from sump level to the middle of the cavern height. In the course of the repair process and the new completion of cavern K2 with considerable time consumption the lower 33 m of the 13 3/8'' casing were milled for integrity purposes and the packer with the 9 5/8'' welded tubing was correspondingly set at a higher level. The gas re-filling went without any difficulties apart from the contact of the leaching string with the sump at the beginning of the re-filling process. The produced volume of brine, as expected, was far above the volume of the sonar measurement (+76,500 m{sup 3}) and only slightly higher than the volume of the evaluation of the leaching process (+17,000 m{sup 3}), which is due to the irregular cavern shape caused by hard salt layers (Kieserite).

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

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

    For analysis and evaluation of acoustical signals from technical processes different approaches are used. In the field of non-destructive testing and acoustic diagnostics signals are increasingly complex. The following paper presents approaches for the automatic classification of technical signals for typical examples. Signals with higher complexity require more performant algorithms like DTW (Dynamic Time Warping) and HMM (Hidden-Markov-Models), which are already applied successfully in speech processing.

    To reduce the time from symptom onset to treatment with tissue plasminogen activator (tPA) in ischemic stroke, an ambulance was equipped with a CT scanner. We analyzed process and image quality of CT scanning during the pilot study regarding image quality and safety issues. The pilot study of a stroke emergency mobile unit (STEMO) ran over a period of 12 weeks on 5 weekdays from 7a. m. to 6:30 p. m. A teleradiological service for the justifying indication and reporting was established. The radiographer was responsible for the performance of the CT scan on the ambulance. 64 cranial CT scans and 1 intracranial CT angiography were performed. We compared times from ambulance alarm to treatment decision (time of last brain scan) with a cohort of 50 consecutive tPA treatments before implementation of STEMO. 62 (95 %) of the 65 scans performed had sufficient quality for reading. Technical quality was not optimal in 45 cases (69 %) mainly caused by suboptimal positioning of patient or eye lense protection. Motion artefacts were observed in 8 exams (12 %). No safety issues occurred for team or patients. 23 patients were treated with thrombolysis. Time from alarm to last CT scan was 18 minutes shorter than in the tPA cohort before STEMO implementation. A teleradiological support for primary stroke imaging by CT on-site is feasible, quality-wise of diagnostic value and has not raised safety issues. (orig.)

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

    About one third of all German shopping centers are more than 30 years old and require revitalization. The necessity of revitalization does not depend on age but on the profit made by the shopping center. It can be stated that revitalization measures must be made in ever shorter intervals, owing to the more rapidly changing wishes of the customers. Further, there are different time intervals for different service areas. (orig.)

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

    To protect climate, the aviation industry is asked to reduce GHG emissions. A possible measure to achieve this goal is the increased use of biokerosene. One possible way to provide biokerosene is through liquefaction of biomethane. This biomethane can be produced by anaerobic fermentation from large variety of organic waste streams. Considering this background, an overview of the overall process chain for the production of biokerosene from biomethane is given. The starting point for the analysis is the Gasto-Liquid-process (GtL). This process is described in detail focusing on the differences between autothermal and steam reforming of biomethane. Based on this, two reference concepts are designed, modeled, and simulated. The results of this simulation are then evaluated according to predefined technical parameters. Finally, the defined concepts are analyzed economically, i.e. the production costs are assessed and the key parameters defining the results are identified.

    Electricity consumption in German households accounts for more than 10% of energyrelated CO{sub 2} emissions. In spite of substantial improvements in, for example, the efficiency of household appliances, there is still a considerable electricity savings potential to be tapped in this sector. The possible contribution that the German residential sector can make to climate protection is correspondingly large. This working paper aims to structure and quantify electricity savings potentials which could be exploited in German households either through investment measures or changed user behaviour. The total theoretical potential which can be tapped through the purchase of efficient household appliances and the replacement of electrical heaters and hot water generators (i.e. by encouraging investment) amounts to approx. 90 TWh/a. This corresponds to more than 60% of the current electricity demand of all German households. By means of changed user behaviour, approx. 30 TWh of electricity could be saved according to our calculations. The assessment of energy savings potentials is an important step towards identifying those potentials which are most significant with regard to their volume, the barriers against their deployment and the design of appropriate policy. The results of the analysis give indication which areas should be dealt with as a matter of political priority in order to maximise the effects of political instruments in the area of demand side related electricity efficiency.

    The contribution under consideration reports on a supply of an infrastructure for the generation of a comprehensive integrated information system for tenants, landlords and providers. With the prototypical acquisition of building conditions and the input of relevant data in a local data base, technical obstacles already have been overcome. The planning and partial implementation of the local data base for the targeted and structured acquisition of inventory data supports a holistic view of all energy-related processes. The comprehensive analysis of all building management processes and future goals of information by all participants is the basis for high quality data. The system concept is designed so that a global data base is created. This database allows observations of the user behaviour, efficiency and costs, and an assessment of technical components such as durability and contribution of energy efficiency. Cross-sector relationships are revealed by means of analytical methods such as data mining.

    The trend to torque motors does not only continue since the beginning of a new millennium, but is still increasing at the moment. This development is essentially pushed by branches of producing industries, e.g. plastics, printing, wire drawing and machine tool industry. The replacement of hydraulic drives by electric drives e.g. with plastics machines step by step means a first essential step towards the right direction, particularly this development is seen from the angle of energy consumption. The high torques and low speeds of the hydraulic drives can be produced by gear motors for example. Meanwhile torque motors become standard program of numerous manufacturers, so that, by its application, there are not only advantages of direct propulsion technology to reach in principle, but also reductions of processing times and energy consumption. In consideration of less marginal condition the relationship of moment of inertia and accelerating values achieved by torque motors in comparison to gear motors is derived and based on performed motors the energy efficiency assuming different load cycles is compared.

    The authors of the contribution under consideration present a platform for the active participation of consumers and producers at the decentralized energy market with dynamic pricing of the electricity. A profitable operation of these prosumers is a prerequisite for their widespread market participation. The authors describe in detail the technical barriers for the market participation of the prosumer and develop a possible approach for the technical realization of the integrated market access. Markets with decentralized structures require a dedicated infrastructure of communication. In this case the proven key technology of the Internet Protocol is used. This requires an IP enabled network component in decentralized systems. The Internet-based connection of consumers and producers enables an automated participation in energy markets. In order to ensure a security of supply, such a scheme has to meet real-time criteria and high security requirements. When communicating via the Internet the accessibility of each plant from everywhere can be realized. This enables a cross-regional clustering of prosumers who otherwise would be excluded by market entry barriers to an active participation in the energy market. For the creation of a market any prosumer must have the free choice of the trading platform. The authors discuss the resulting additional demands on the system architecture.

    Purpose: to evaluate the technical and clinical success rates of percutaneous stent revascularization in the treatment of chronic mesenteric ischemia (CMI). Patients and methods: 17 patients (12 female) with typical symptoms of CMI were treated by percutaneous stent placement for stenoses of the splanchnic arteries (celiac trunk; superior mesenteric artery, SMA; inferior mesenteric artery, IMA). The primary and secondary technical success, primary and secondary clinical success, and the long-term clinical outcome were determined. Results: a total of 24 stents were implanted in 21 splanchnic arteries (12 stents in the celiac trunk, 11 in the SMA and 1 in the IMA). The primary technical success rate was 91% (19/21 arteries), the secondary technical success rate was 95% (21/22 arteries). Clinical follow-up was available for 16 patients. The primary clinical success rate was 81% (13/16 patients). Following two secondary interventions, the secondary clinical success rate was 94% (15/16 patients). Long-term clinical success was achieved in 15 of 16 patients (94%) with a mean follow-up of 26 months. One patient died within 30 days of the intervention and two patients demonstrated major complications (1 dissection, 1 stent dislocation). None of the patients required surgical revascularization and none of the patients died due to recurrent mesenteric ischemia. (orig.)

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

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

    Not unlike thermoablation of liver metastases, thermoablation of metastases to the lungs is gaining clinical interest. Radiofrequency ablation and laser-induced interstitial thermotherapy are both used clinically. Initially it was suspected that percutaneous treatment of lung metastases would result in a rate of pneumothoraces and tissue reactions which would not be clinically acceptable. However, this did not prove true. Fear of pneumothoraces however did lead to the desire for an applicator with a maximally reduced diameter. While clinical results are not yet available, technical success rates of laser-induced interstitial thermotherapy of lung metastases are promising. The percentage of pneumothoraces does not differ significantly from that seen in diagnostic procedures. Large metastases may be treated by simultaneous use of multiple applicators or by repositioning of an applicator (pullback technique). Surgical experience is still guiding us in deciding which primaries' metastases may be successfully treated percutaneously. The literature indicates that lung metastases from colorectal primaries are especially suited. Radiotherapy is only an alternative method in cases of lung metastases if they cause symptoms (such as pain because of thorax infiltration or difficulty in breathing because of bronchial lesion). Due to the risk of radiation-induced pneumonia general radiotherapy is not to be recommended. The possibility of stereotactic ray treatment is being considered, but because breathing shifts the metastases it is not yet feasible. Therefore, percutaneous thermoablation could be used as a minimally invasive, rather riskless therapeutic option for a relatively high percentage of inoperable lung metastases. (orig.) [German] Die Thermoablation von Lungenmetastasen ist dabei, sich aehnlich erfolgreich im klinischen Alltag zu etablieren wie die heute weit verbreitete Thermoablation von Lebermetastasen. Bei beiden Metastasierungsformen kommen die Radiofrequenz-(RF-)Ablation und die laserinduzierte Thermotherapie (LITT) zum Einsatz. Befuerchtungen, dass die perkutane Behandlung von Lungenmetastasen zu nicht akzeptablen Pneumothoraxraten und nicht tolerierbaren Lungenreaktionen fuehrt, haben sich bisher nicht bestaetigt. Wegen der Gefahr eines Pneumothorax werden Zugangssysteme mit moeglichst geringem Durchmesser bevorzugt. Auch wenn klinische Ergebnisse derzeit nur in unzureichendem Masse vorliegen, existieren jedoch verlaessliche Zahlen zum technischen Erfolg der Methode. Die Pneumothoraxraten liegen insgesamt in dem Bereich, der bei diagnostischen Punktionen beobachtet werden kann. Groessere Metastasen koennen wie bei der Ablation von Lebermetastasen durch gleichzeitigen Einsatz mehrerer Laserapplikatoren oder durch konsekutive Umpositionierung eines Applikators behandelt werden. Zur Beantwortung der Frage, welche Primaertumoren eine erfolgreiche Behandlung von Lungenmetastasen zulassen, kann die chirurgische Literatur herangezogen werden. Gesichertes liegt hier v. a. fuer Lungenmetastasen kolorektaler Karzinome vor. Die Strahlentherapie stellt bei Lungenmetastasen nur dann ein Alternativverfahren dar, wenn diese eine Symptomatik verursachen (z. B. Schmerzsymptomatik bei Thoraxwandinfiltration oder Luftnot bei Bronchusalteration). Eine generelle Strahlentherapie ist bei Lungenmetastasierung aufgrund der Pneumonitisgefahr nicht zu befuerworten. Die Moeglichkeit einer stereotaktischen Bestrahlung wird zwar diskutiert, ist aber aufgrund der Atemverschieblichkeit der Metastasen derzeit noch nicht praktikabel geloest. Somit koennte die perkutane Thermoablation bei einem relativ hohen Prozentsatz nichtoperabler Lungenmetastasen als minimal-invasive, komplikationsarme Therapieoption eingesetzt werden. (orig.)

    Fuel cells open up a new and exciting option for energy conversion at high efficiency of fossil fuels into electrical energy with the minimum emission of noise and pollutants. The fuel cells which are of interest to the power plant builder are the phosphoric acid fuel cell (PAFC), the melting carbonate fuel cell (MCFC) and also the ceramic oxide fuel cell (SOFC), since, with these, high system efficiencies in the production of electrical energy can be obtained through the opportunity to utilize waste heat.

    Patients and Methods: The presented data refer to a retrospective univariant examination of 67 patients, which have been treated for IPP with soft X-rays in the Dermatological Clinic of the Technical University of Munich between 1990 and 1995. The aim of the study was to examine, how far a progression of the disease can be stopped with soft X-rays and how the pain symptomatic is reduced. Results: In 58 of 67 examined patients (86.6%) a progression of the disease could be stopped. 25 out of 67 patients (37.3%) complained of pain before therapy. This symptomatic mostly improved totally in 21 patients (84% of the patients with pain). A complete or partial dissolution of the indurations was to be noticed in 41 of 70 indurations (58.6%). In 23 of 60 patients (38.3%) an improvement or totally regression of the deviation was observed. It could be shown that therapeutic outcome significantly correlates to a shorter duration of anamnesis (p < 0.05), smaller plaque size (p < 0.025) and a tendency to lower age of the patients. Conclusion: Radiotherapy of Morbus Peyronie is extremely effective and has a low rate of side effects. (orig.)

  20. SURCARBUREX the knock-resistant exhaust gas mixer for high compression motors

    Energy Technology Data Exchange (ETDEWEB)

    1944-01-01

    This device was designed to be attached to both diesel and gasoline engines which were converted to use either substitute liquid fuels such as alcohols, or gases produced by gas generators. The advantages claimed in the prospectus include change-overs from replacement fuels to normal gasoline in a very short time. Also, increased power in mountainous areas was claimed. The unit's basic function was to strip exhaust gas after it left the manifold, and to re-cycle it through the carburetor to be mixed with new gas. In this way, the unburned hydrocarbons dilute the incoming air-fuel mixture. The prospectus claims that gasolines with low octane ratings, 55-65, run in engines equipped with the SURCARBUREX react as if using higher rated fuels. Power output, according to a chart, is improved with the exhaust mixture, and results in no knocking with 65-octane fuel. On the other hand, the same octane rating without the exhaust addition provides less power and produces a knock. A test conducted at the Technische Hochschule, Muenchen, basically agreed with information in the prospectus which indicates increased power and less engine wear. However, it appears that with use of 70-octane, the device creates little useful assist to an engine with lowered compression ratio, while the lower-octane seems satisfactory with a low compression ratio and exhaust gas mixture. Testing was carried out using a four-cylinder car motor and a heavy-duty diesel truck engine in both bench and on-the-road analysis by the Geneve firm. The technical school used test motors of one cylinder or small displacement. The general result was favorable, since it appeared to be rather economical to install, versatile, and spared using high-grade gasoline when other substitutes were not available. 5 figures, 6 graphs.

    The processes in the freeboard of a fluidized bed combustor have an important impact on both the elutriation of fly ash particles and the emission of noxious gases. The main features have been studied for already several decades. In order to understand the phenomena more thoroughly, the details have to be studied. This paper presents the results of measurements of the gas velocity at different locations in the freeboard. Experiments were performed in the pressurized fluidized bed combustor of the Delft University of Technology, The Netherlands, at 8 bar and a freeboard temperature of 850 C. The measuring method used the temperature flucutations naturally present in the combustion process which were recorded by axially displaced thermocouples. By means of mathematical correlation of the recorded signals, the local gas velocity is calculated. The resulting radial velocity profiles of the upper part of the freeboard are very similar to one-phase turbulent pipe flow profiles. Deviations from the expected axial symmetrical velocity profile which were measured at the lowest level are described to the non-axial symmetrical bed behaviour. (orig.)

    The radiation exposure encountered in revisions and demolitions of some areas of nuclear facilities requires the use of remotely operated technical systems in order to avoid the personnel being exposed in the course of such work. The main activities conducted within such areas include inspecting, measuring, cleaning, cutting, and handling. The Institute for Materials Research (IW) of th University of Hannover, with its twenty years of experience in basic and application-oriented research and development in the field of thermal cutting, especially in plasma fusion cutting, and ten years of development of remotely operated handling systems, offers its services as a partner in solving these problems in nuclear plants. Besides stationary systems, IW has developed also mobile robots and manipulators able to move largely autonomously under remote control within a certain area. (orig.)

    In 1994-1996, Fernwaerme Wien GmbH began to develop an area of South-East Vienna which is almost wholly used by market gardeners. Self-prestressing preinsulated bonded pipes in accordance with EN 253 with diameters DN 50 to 600 were cold-laid. In 1999, the leak detection system indicated faults in four isolating valves on branch connections. Several ball valves (material St37) cut out of the pipe following detection of one or more leaks were subjected to closer examination at the Technical University of Vienna. Several cracks extending from the inside outwards were found in the vicinity of the fillet weld on the tapered part of the casing pipe of the ball valves with a cold-formed tubular casing. Several cracks in the vicinity of the orbital weld were distributed around the entire circumference of the casing pipe of the ball valves with a straight casing. The Technical University of Vienna was commissioned to measure the loads affecting the valves during operation. Strain gauges and a temperature sensor were fitted to the pipe in the vicinity of the joint after the ball valves had been replaced. Measurement cables were connected externally through an opening in the joint shell and the joint then packed with foam material. Expansion and the system temperature and pressure of the domestic connection were recorded throughout several temperature cycles. (orig.)

    The Second Technical Report of the project `Saisonal Storage of Solar Low Temperature Heat in Mines` describes different concepts to realize seasonal storage in mines and suitable district heat systems. The different storage designs and concepts are presented and evaluated in detail. The fundamental differences between the use of a tunnel or a shaft are discussed as well as the storage filling with a fluid or a mineral material. Technical solutions for the integration of a seasonal storage in mines are examined. Different solutions for storage sealing stand for choice. It is shown that the use of air-placed concrete represents a particularly suitable method due to the cost advantages and the flexible operation of the procedure compared with other seal systems. An exemplary system design leads to specific investment costs of 115 DM/m{sup 3} to 300 DM/m{sup 3} for the saisonal storage depending on the boundary conditions (tightness of the surrounding rock, use of available pipework etc.). The latter amount equals the height of the costs payed for the concrete underground tanks in Hamburg-Bramfeld and Friedrichshafen. It is shown that the costs for the use of mines for saisonal storage is comparable to those of existing systems at least; in favorable cases definitely lower costs may be achievable. In any case, a specific evaluation, taking account of local boundary conditions and circumstances, is necessay. On the basis of the boundary conditions below and the situation above ground, many locations in the Ruhr area were estimated concerning their suitability for this project. Favorable locations could be found within almost all coal industry areas. The plan for house buildings at these locations is suitable for the application of a district heat network. Although the examination of seasonal heat storage in mines is not concluded up to now, the presently achieved information indicates very positive results in all sections (i.e. investment costs, technical feasibility, choice of location).

    The First Technical Report of the project 'Analysis of Seasonal Storage of Solar Heat in Mines' describes the local terms of construction and operation of a shaft storage at the 'Bergwerk General Blumenthal/Haard' in Recklinghausen. For the installation of a pilot storage the Shaft No. 6 should be chosen because of the better condition of the shaft walling and the greater diameter in comparison with Shaft No. 2. As the result of the objective of operational reliability only the leakproof metal tubbing array in the shaft should be used. In compliance with this rule, a system with a volume of 2,155 m{sup 3} is designated for the Shaft No. 6 (storage height 63 m). The storage is only insulated at the top. A gravel/water filling guarantees static strength of the site. With a vertical distance of 1.5 m, 42 pipe coils should be installed, evenly distributed across the cross section and connected to 10 temperature-dependent controllable layers. Each pipe coil consists of 100 m steel pipes with an inside diameter of 2.5 cm. Simulation calculations show that storage efficiencies higher than 80% can be expected. The efficiencies and the discharged energy considerably depend on the temperature level of the district heat netowrk. The collector area and the quantity of heat have a comparatively smaller influence on the storage operation results. The specific investment costs of the shaft storage at the location 'General Blumenthal 6' were calculated to 477 DM/m{sup 3}. A reduction of the specific costs can be achieved especially by the use of larger storage volumes in the future. (orig.) [German] Im vorliegenden Bericht werden die Rahmenbedingungen fuer den Bau und Betrieb eines Schachtspeichers am Beispiel des Standortes Bergwerk General Blumenthal/Haard in Recklinghausen konkretisiert. Da der Schacht 2 in einem deutlich schlechteren Zustand ist und einen kleineren Schachtdurchmesser aufweist, ist es sinnvoll, den Schacht 6 fuer die Installation eines Pilotspeichers zu nutzen. Aufgrund des Zieles einer moeglichst hohen Betriebssicherheit sollte fuer den Schachtspeicher der eigendichte Abschnitt mit Tuebbingausbau, der in diesem Fall bis 70 m Teufe reicht, verwendet werden. Abzueglich eines unteren Ueberlappungsbereiches und des Schachtkellers ergibt sich somit eine nutzbare Speicherhoehe von rund 63 m, was einem Volumen von etwa 2.155 m{sup 3} entspricht. Der Speicher wird nur am Kopf waermegedaemmt. Der Schachtspeicher wird mit einer Kies/Wasser-Fuellung versehen. In diese werden mit einem vertikalen Abstand von 1,5 m insgesamt 42 Rohrschlangenebenen eingebracht, die jeweils aus gleichmaessig ueber die Querschnittsflaeche verteilten Stahlrohren DN 25 mit einer Gesamtlaenge von knapp 100 m bestehen. Diese Ebenen werden zu insgesamt 10 temperaturabhaengig ansteuerbaren Schichten zusammengefasst. Durchgefuehrte Simulationsrechnungen zeigen, dass ein Grubenspeicher im quasistationaeren Zustand Nutzungsgrade von ueber 80% erreichen kann. Die Nutzungsgrade und damit die nutzbaren solaren Waermemengen haengen vor allem vom Temperaturniveau des Nahwaermenetzes ab. Die Groesse der Kollektorflaeche und die Hoehe der Waermelast der Verbraucher haben nur einen vergleichsweise geringen Einfluss auf die Leistungsfaehigkeit des Speichers. Bei positiver, aber realistischer Einschaetzung der Randbedingungen ergeben sich fuer den projektierten Pilotspeicher am Standort General Blumenthal 6 spezifische Investitionskosten in Hoehe von 477 DM/m{sup 3}. Eine Verringerung dieses Wertes ist vor allem durch die Vergroesserung des Speichervolumens bei zukuenftigen Anlagen moeglich. (orig.)

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

    The main aim of research and development in the field of internal combustion engine is to create an engine with low fuel consumption and hence low carbon dioxide emissions to meet future emissions regulations as well as providing a good driving experience. Homogeneous charge compression ignition (HCCI) is an alternative combustion process being currently developed that promises a good fuel consumption rate and low nitrogen oxide emissions for the gasoline engine. The only legally restricted exhaust gas emissions for this combustion process are carbon monoxide (CO) and hydrocarbons (HC). The aim of this research was a better understanding of the causes and sources of hydrocarbon emissions with HCCI using gasoline so as to further reduce hydrocarbon emissions. A description of the HCCI combustion process is followed by a list of the known sources of hydrocarbon emission in conventional gasoline engines and current knowledge of the causes of hydrocarbon emission with HCCI. It is assumed that many of the known causes of hydrocarbon emissions in the conventional gasoline combustion process are the same for HCCI. For this reason, this study focused on combustion and carburation, which is where the combustion processes differ the most. (orig.)

    The wish to go easy on global oil-resources and the compatibility of environment and traffic are subject of public interest. Therefore, measures must be taken for gasoline engines regarding fuel consumption and CO{sub 2}-emissions. The dethrottling of the intake system by means of residual gas recirculation is a well known measure to reduce the fuel consumption. However, high residual gas concentrations cause a delayed combustion and increased cyclic variations. The specific initiation of charge motion and turbulence in the combustion chamber accelerates and stabilizes the combustion and thus compensates the effects caused by high residual gas concentrations. Because of these complex interactions it is desirable to have the possibility to evaluate the residual gas tolerance of the combustion process at low-load engine operation already during the concept phase. Therefore, it was the aim of this study to develop a method based on numerical simulation that allows a prediction of the combustion stability margin for SI engines with homogeneous combustion for arbitrary in-cylinder flow. Investigations that were carried out with the CFD-method confirmed the acceleration of the combustion with increased turbulence. Further the supporting effect of charge motion on mixture preparation could be pointed out. However, combustion processes with highest swirl-numbers caused a vertical mixture stratification in the combustion chamber with lean mixture at the spark plug resulting in a lower residual gas tolerance. A threshold for a stable combustion could be determined by analyzing the properties of the cylinder charge by means of the flame theory method what further enabled the prediction of the residual gas tolerance of the combustion process and the potential to reduce the fuel consumption. A good correlation between the predicted values of the external residual gas recirculation rate and measurements at the engine test bench could be found. Although improvements of the simulation of the turbulent flow, mixture preparation and combustion are to be expected the developed method is in any case a possibility to predict quickly and reliable the residual gas tolerance of homogeneous combustion processes.

    The author describes algorithms for more effective use of the components of hybrid drives. An adaptive electrical energy management concept (AEE) is developed which can integrate infrastructure and traffic data to result in a predictive electrical energy management concept (PEE). The AEE wasa designed specially for the low-cost Mild Hybrid engine and has fuel consumption advantages of 1 to 1.5 percent. The AEE is a software function and requires no additional hardware. The PEE has an additional driving situation awareness function, which results in 10 percent fuel savings as compared to conventional strategies. As a basis for the AEE and PEE, a conventional energy management strategy on the basis of analytical, heuristic component models is described. (orig.)

    The nuclear reactor accident at Chernobyl was a challenge to nuclear and radiological technical institutes with regard to performance and credibility. At the Nuclear Chemistry Institute in Marburg, over 6000 separate samples were studied for radioactivity from the destroyed Chernobyl reactor. The variety of the samples ranged from air, rainwater, grass and soil to mothers' milk, very different foods, animal fodder, living animals or air filters, sewage sludge etc. About 80% of the samples came from Marburg-Biedenkopf, some from the surrounding areas in Hesse and from other Federal States, and a small proportion from other European countries including the Eastern Block.

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

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

    The paper presents fundamental studies on natural biosorption to algae of heavy metals. The investigations were carried out by TU Berlin University in a special research project (Sfb 193, 'Biologische Behandlung industrieller und gewerblicher Abwaesser'). The chlorophyceae C. vulgaris was used as reference alga, and 38 further algae were analzyed with regard to their sorption characteristics for lead, cadmium, nickel and zinc. The most effective algae were the chlorophyceae C. salina, the cyanophyceae S. hofmani and L. taylorii. The biosorption characteristics of C. salina and L. taylorii were investigated in detail. L. taylorii was found to be exploitable successfully in a technical process, so the investigations were extended to include copper. Knowledge about the chemical processes of biosorption is important for any attempt to modify the biosorption characteristics. Experiments on the incorporation of additional functional groups in the cell wall polysaccharides of the algae were carried out with a view to enhancing capacities and influencing selectivities. (orig.) [German] In der vorliegenden Arbeit wurden Grundlagenkenntnisse ueber den natuerlichen Prozess der Biosorption von Schwermetallen an Algen erarbeitet.

Ausgangspunkt der Arbeit stellten Untersuchungen an der Chlorophyceae C. vulgaris dar. In einem anschliessendem Screening, das sich aus der Charakterisierung der Biosorption an C. vulgaris ableitete, wurden 30 weitere Algen aus unterschiedlichen taxonomischen Klassen auf ihre Sorptionsfaehigkeiten gegenueber den Schwermetallen Blei, Cadmium, Nickel und Zink untersucht. Die einzelnen Algen zeigten eine grosse Bandbreite in den Biosorptionsleistungen. Zu den leistungsfaehigsten Arten zaehlten die Chlorophyceae C. salina, die Cyanophyceae S. hofmani and L

    Diesel engines were actually designed for fossil fuels. For this reason an operation with substitute fuels poses a special challenge. For example native oils/fats are elements comprising a range of more than 5000 chemically different substances. Each of these has individual characteristics which have to be considered during operation. Hence, an adapted operation is necessary. Typical damages include: 1. Cavitation pitting in the fuel injection system. 2. Precipitation of combustion residues in inlet and outlet. 3. Engine damages caused by lube oil dilution. 4. Engine damages caused by agglutination of lube oil. 5. Plugging of fuel conduit and filter systems caused by polymerization reactions. Practice has shown that the operational mode of engines are not generally reproducible. It is a fact that engines of the same type and manufacturer show a different operating performance. This is due to catalytic effects which can be traced back to the consistence of the material grade. Traditionally the material grades of these engines are designed for basic fuels. In contrast to that most of the substitute fuels (oils/fats) have distinctive acidic characteristics. The question in how far the catalytically active surfaces boost or avoid polymerization is part of current researches. (orig.)

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

    The use of electric tumble dryers in the Netherlands increases at a great pace. Holland Energy Systems (HES) developed a prototype solar wash dryer in which the advantages of open air drying and electric drying are combined. The dryer consists of a transparent plate with an air cavity behind it. On the innerside of the air cavity is a metal dark-colored plate, the absorber. Behind this solar collector is the actual drying space, equipped with mobile racks for the laundry. If the sun does not produce enough heat the outside air will be heated electrically. The dryer also contains a flat water tank to store heat at the bottom of the drying compartment. In this report attention is paid to the architectural implementation possibilities of the solar wash dryer and the adjustments that might be made in the design of a house. Next to architectural aspects also juridical and societal aspects are discussed, in particular concerning the fitting-in of the housing construction. figs., tabs., 5 appendices, 11 refs.

    Full Text Available [english] Purpose: Anatomy is an important subject in the education of radiographers and radiotherapy technicians. The enormous amount of information may render efficient learning more difficult and lead to sub-optimal results. The purpose of this study was to test whether the introduction of a computer-based tutorial enhances learning success in anatomy. Methods: A commercially available tutorial in anatomy especially adapted to the requirements of the education of radiographers and which facilitated and structured the frequent repetition of the material was introduced into the conventional curriculum. The tutorial was used during normal lessons, and work with it was obligatory. The students could learn anatomical structures and landmarks repeatedly as well as test themselves. The scores obtained in the final examinations two years prior to introduction of this tutorial were compared with those obtained two years after introduction. Results: Students’ knowledge in anatomy could be markedly improved. Conclusion: An efficient and time-saving method of learning became possible. It was important to integrate the tutorial into the normal curriculum. The test results show the feasibility of this educational concept. [german] Zielsetzung: In der MTA-Ausbildung nimmt Anatomie einen wichtigen Platz ein. Die große Stofffülle erschwert jedoch ein effizientes zeitsparendes Lernen und führt auch bei motivierten Schülern oft zu mangelndem Lernerfolg. Es sollte geprüft werden, ob dieser durch Einführung computerbasierten Lernens verbessert werden kann. Methodik: Ein auf die Erfordernisse der MTRA-Ausbildung von den Autoren angepasstes kommerzielles Anatomie-Lernprogramm, das den Schülern das notwendige häufige Wiederholen des Materials erleichtert und strukturiert, wurde im Rahmen des Pflichtunterrichtes den Schülern zur Verfügung gestellt. Diese konnten damit anatomische Sachverhalte sich einprägen, beliebig oft wiederholen und ihr Wissen testen. Die Examensergebnisse jeweils zweier Jahrgänge vor und nach der Einführung des Programms wurden verglichen. Ergebnisse: Durch die Einführung des Programms konnten die Anatomiekenntnisse von MTA-Schülern bei gleichem Zeitaufwand deutlich verbessert werden. Schlussfolgerung: Durch gezieltes Üben derjenigen Elemente, die noch nicht ausreichend im Langzeitgedächtnis verankert sind, war eine effiziente und zeitsparende Art des Lernens möglich. Wichtig ist eine Einbettung des eLearning-Tools in den normalen Unterrichtsablauf. Die deutlich besseren Examensergebnisse nach Einführung unserer Anatomie-Lernplattform sprechen für die Richtigkeit des Konzeptes.

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

    The share of distributed renewable generation is dramatically growing since years in Germany due to the existing subsidies for renewable energy sources. As a consequence the existing distribution networks and primarily the low-voltage (LV) networks have to change to maintain the same degree of power quality and security of supply. This paper described resulting new challenges, which will have a major impact on the distribution networks. To solve the problems today utilities are mainly focussing on conventional measures, like network extension or adding new substation. Compared to this classical measures new solutions and technologies are described. These solutions shall enable the distribution network operators (DSO) to optimize the necessary investment costs. Finally the main described solutions will be evaluated and compared to the conventional measures using three typical and realistic LV networks. For each network the share of renewable energy is adjusted in different steps and the impact on the network is assessed taking into account the technical as well as the economic behaviour. (orig.)

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

    After several years of low acceptance, miniature CHP systems are rapidly gaining ground in domestic power supply. Apart from the established technology of gas-fuelled CHP systems, there are also new incentives from legal regulations, e.g. the Reimbursement Act, the Act on Combined Heat and Power Generation of 2009, and the Act on Renewable Energy Sources. The contribution analyses the various modes of operation of miniature CHP systems in a low-voltage grid in an attempt to show the effects of enhanced decentral power generation on the public power supply grids.

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

    The report investigates the technical feasibility of using the HTR modular reactor for steam supply to tertiary oil recovery, and for hydrogen recovery from the resulting petroleum gas. The report focusses on the design of the two main components, HTR modular reactor with a steam generator, and HTR modular reactor with a steam reformer, and on explaining the alternative system concepts feasible by varying the mode of combination of the two main components. Also, the design concept of a system for heat transport using nuclear long-distance energy (ADAM and EVE) is explained. The technical aspects of the required water treatment system and of the gas production unit for hydrogen recovery are discussed. (orig.).

    At the end of the 20th century, environmental destruction, climate change and forest die-back demonstrate that ecological issues, besides economic and technical ones, need to be considered in political and economic decision-making as criteria of equal rank. Complete budgeting, which takes into account all three aspects, by following up the entire life cycle of a product or span of a process can deal with this field of tension. Complete budgeting projects require budgets of individual substances, which are given here for various materials. All the same, this paper can only provide an overview; detailed, product-specific data are beyond its scope. (orig.)

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

    Due to its high efficiency and environmental friendliness, which is accounted for by its perfect adaptability to natural gas, the SOFC high-temperature fuel cell is especially well suited for decentralised power and heat supply systems. While the planar SOFC version is still largely in the development stage, with units of up to 10kW under study at various research institutions, the pipe version of Siemens Westinghouse has already reached a more advanced technical stage. A first 100 kW demonstration plant is being operated in the Netherlands by the Dutch/Danish EDB/ELSAM consortium. Despite certain starting difficulties the first 6,000 operating hours showed a very satisfactory behaviour. Net electrical efficiency reached 46%, a globally unrivalled achievement for a plant of this size. Using this concept as a starting point Siemens plans to put demonstration plants of up to 3 MW into operation in the course of the next three years. [German] Die Hochtemperatur-Brennstoffzelle SOFC ist aufgrund ihres hohen Wirkungsgrades und ihrer Umweltfreundlichkeit und durch den problemlosen Einsatzes von Erdgas besonders gut fuer die dezentrale Versorgung mit Strom und Waerme geeignet. Waehrend sich die planare SOFC noch weitgehend im Entwicklungsstadium von Einheiten bis 10 kW befindet und in Deutschland vorwiegend an Forschungseinrichtungen untersucht wird hat das Roehrenkonzept von Siemens Westinghouse bereits einen fortgeschrittenen technischen Stand erreicht. Eine erste 100 kW Demo-Anlage wird in den Niederlanden von dem hollaendisch/daenischen Konsortium EDB/ELSAM betrieben. Trotz einiger Startschwierigkeiten zeigten die ersten 6000 Betriebsstunden ein sehr zufriedenstellendes Verhalten. Mit 46% elektrischem Nettowirkungsgrad wurde ein fuer Anlagen dieser Groessenordnung bislang weltweit einmaliger Wert erreicht. Die Siemens AG plant, basierend auf diesem Konzept, in den naechsten drei Jahren Demonstrationsanlagen bis 1 MW in Betrieb zu nehmen. (orig.)

    Heating costs form the main part of the total energy cost of commercial sow operations. Within a commercial sow farm, most of the energy usage occurs in the farrowing compartment, because the temperature requirement is high for the suckling piglets. It was examined whether a reduction in temperature setting of 2C in combination with an adequate micro-climate for suckling piglets can contribute both to energy savings and improvement of lactating sow performance. In total, 96 sows were used in this study. The study was conducted in four naturally ventilated farrowing compartments (six sows per compartment) with a combination of indirect and direct air-inlet during November 1996 and May 1997. In the compartment with the standard temperature setting (control), the `set point for heating` and `set point for ventilation` were set at 21C and 23C, respectively, when all sows in the compartment had produced their litter. In the experimental compartment, both set points were reduced with 2C. A hoover with local heating was installed in each pen of the experimental compartments to provided the suckling piglets with an appropriate micro-climate. In total eight batches of sows were followed in the winter period. After each batch, the control and experimental treatments were switched between compartments. In each of the eight batches, a difference in room temperature was realised between the compartment with the standard and reduced temperature settings. The room temperature was on average 1.1C lower in the compartment with the reduced temperature setting. The reduction in room temperature had no effect on lactating sow and piglet performance. In conclusion it is possible to reduce the room temperature in naturally ventilated farrowing barns, where the air-inlet is direct and the optimum micro-climate of the suckling piglets can be guaranteed using a hoover. Energy savings in the compartments with reduced temperature settings mounted to DFI 3 per sow and year, without negative effects on lactating sow and piglet performance. The increased cost for electricity (DFl 3.50 per sow and year) can be avoided when using floor heating and letting the call light in the hoover burn for only a few days after farrowing. 5 refs.

    In the Federal Republic of Germany, the long-term discussion on an adequate differentiation of utilization and removal of wastes in incineration plants and other combustion plants has ended in dead-ends. Actually, wastes energetically are used in an incineration plant. Theoretically, in the jurisdiction and in the literature this possibility is denied. The general expectation that the actual change of the waste framework directive of the European Union points a way out of this dead-end threatens to be disappointed. The reason is the proposal of an energy efficiency criterion and the necessary calculation parameter for this. Both do not lead to a measurable result. Instead of this, different percentages are calculated as energy efficiency criterion. The solution of this dilemma may be the differentiation between the facts level and the legal consequence level for the differentiation decision. The statement whether the combustion of certain wastes in a combustion plant represents a utilization or not, is a fact question. On the legal consequence side, the possibility should be granted of modifying the legal consequences attached to the utilization. By it, the conflict between engineering science and jurisprudence only can be avoided.

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

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

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

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

    Due to the planned phase-out of nuclear energy and the liberalisation of the energy markets decentralised energy supply system with small-scale or micro-cogeneration plants will become more important in the future. The economic success of these plants hinges on the costs that self-producers are able to avoid and on the revenue they make through feed-in compensation. The decisive success factor is a high electricity requirement of the producer himself, which he does not always have however. A conceivable option for making the use of micro cogeneration plants economically attractive also for operators without a sufficient electricity requirement of their own is to bundle unused production capacities in virtual power plants to make them available to power suppliers as a reserve in case of power plant failures or deviations from load forecasts. In this way a new potential for value creation could be tapped for micro cogeneration plants. This should lead to a more widespread use of this technology, which is distinguished by low CO{sub 2} emissions and avoidance of primary energy use.

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

  12. Information transfer through quantum channels

    2007-03-12

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

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

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

Anliegen des Fachgespraechs war es, Positionen der Technikphilosophie, der Allgemeinen Technikwissenschaft, der Technikgeschichte und der Technikdidaktik zur 'Konzeptualisierung' des Technischen als Grundlage fuer das generelle Verstaendnis von Technik bzw. eines wissenschaftlich fundierten 'Technikbildes' zusammenzutragen, zu vergleichen, aufeinander zu beziehen und fuer die curriculare Arbeit im Rahmen der Konzeptionierung einer allgemeinen technischen Bildung in allen Schulstufen nutzbar zu machen. Die Beitraege sind entsprechend den zwei Schwerpunkten der Tagung gruppiert: Einerseits geht es um Bestimmungen bezueglich eines zeitgemaessen Technikbegriffs ('Technikbild'). Hier gilt es auch historisch-genetisch den Technikwandel zu charakterisieren und so die Technik als Menschenwerk, als wesentliches Element unserer Kultur zu erschliessen. Dabei muss es zugleich auch gelingen, zukuenftige Entwicklungen zu prognostizieren bzw. moegliche Entwicklungspfade sichtbar zu machen, um den Wandel durch Basisinnovationen zu erfassen. Auf dieser Basis werden dann zweitens, gestuetzt auf die Bildungstheorie, Konsequenzen fuer eine zukunftsorientierte technische Allgemeinbildung fuer alle Schuelerinnen und Schueler

    German universities of applied sciences are characterized by applied specialty setting in-tegrated deeply into the transformation and development of regional industry and flexible choice policy of students’ specialties. Taking Deggendorf Institute of Technology as an example, the prac-tices of applied specialty setting and students ’ specialty choices of German universities of applied sciences are focused. The advantages of the universities in specialty setting and the students’ spe-cialty choices are discussed. The cultivation orientation of applied professionals can be realized by three ways: establishing a talent demand forecasting and specialty early preditting system;formulating a dynamic specialty evaluation system, and promoting the construction of characteristic specialty and specialty groups that serve diversified sectors of the industry; constructing a distin-guished specialty system catered to the regional industrial development. Secondly, the innovation of the training mode of applied professionals can be promoted by two ways:formulating and implemen-ting the directors or board system participated by industry and enterprises, evaluation system of spe-cialty setting, and performance evaluation system of professionals training, strengthening industry and education integrated specialty setting. Thirdly, specialty settings can be optimized by establishing students’ specialty choice-based specialty competition mechanism.%与区域产业转型发展深度融合的应用性专业设置以及灵活的学生专业选择政策,是德国应用技术大学的显著特征。以德国代根多夫应用技术大学为例,可以得到相关借鉴与启示:第一,建立人才需求预测和专业预警机制、专业动态评估制度,推进服务产业的特色专业和专业群建设,构建契合产业发展、根植当地、特色鲜明的专业体系,以实现应用型人才培养定位。第二,制定和实施行业企业和用人单位参与的理事会(董事会)制度、专业设置评议制度、人才培养绩效评价制度等,加强产教融合的专业设置,推动应用型人才培养模式创新。第三,建立学生专业选择下的专业竞争机制,促进高校优化专业设置,提升人才培养质量。

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

    This project was dedicated to the assessment of the fueling quality of commercial domestic and agricultural furnaces. Emphasis was placed on the assessment of emissions. Certain emission reduction measures were developed, the present state of knowledge of the combustion of biogenic solid fuels was summarized, and a market analysis of furnace supplies was prepared. The three parts of this research report deal with the thermal utilization of biogenic solid fuels - literature study and market analysis of the present state of biogenic solid fuel combustion and systems engineering; the assessment of the emission behavior of solid-fuel furnaces - bench-scale stove and central heating furnace measurements; and the development of a combustion air control system which reduces the emissions of hand-fed wood-fired furnaces - development and testing of a combustion aircontrol system with flue gas sensor and fuzzy logic controller.

    The report investigates the use of HTR modular reactors for tertiary oil recovery in the Emsland oil fields of Ruehlermoor and Georgsdorf with a view to the economic aspects of such a project. The reference plant used for the study is a HTR-2 modular reactor for combined steam and hydrogen generation. In addition, some plant variants are considered (HTR-2 and HTR-3 modular systems) also for steam generation only, in this case providing for the plants' higher steam output to be fed to the oil field, or to be used otherwise without additional cost (e.g. for electricity generation). As the Emsland oil fields are sites where the conditions of application of HTR modular systems are relatively unfavourable, the study also covers an assessment of the economic potentials of larger HTR-4 modular systems and their application at more favourable (foreign) oil fields.

    Project 3611R0801503 of the BMUB/BfS was focused on coordination and implementation of generic technical and organisational activities for assessments of nuclear safety and effectiveness of regulatory systems in foreign countries (with focus to Eastern Europe and in INSC partner countries). To comply with the BMUB objectives and the GRS strategy, the tasks were structured taking into account the specificity of countries and nuclear design series whereas the technical knowledge and results of the analyses were provided to meet the requirements. This final documentation on the project describes the results of the activities from 04/01/2011 through 09/31/2014 on working packages ''Programme Coordination'', ''Project Management'', ''Networks and On-Site Assistance'', ''Project Documentation'', ''Knowledge Management'', ''Design Series Specific Activities'', ''Multilateral Activities'', ''Country Specific Activities'', ''International Institutions'', ''EU Panels'', ''G8 and EBRD Funds'' and ''Network Activities''. The project contributed significantly to a systematic extension and deepening of knowledge in GRS. Also, international cooperation with selected regulators and their TSOs as well as with the IAEA, the EU and representatives of multilateral bodies was intensified. As intended, this allowed to extend the information and knowledge basis for nuclear safety. The know-how gain for GRS is to be rated as high. This is true for the work in international bodies, but also for the creation, further development and usage of national and international information, knowledge and cooperation platforms. By the insights gained from the project, GRS completes and consolidates its knowledge and tools available. The status achieved in the knowledge management development and respective platforms can be estimated as exemplary.

    Full Text Available Salmonellosis cases in the in the United States show distinct geographical trends, with the southeast reporting among the highest rates of illness. In the state of Georgia, USA, non-outbreak associated salmonellosis is especially high in the southern low-lying coastal plain. Here we examined the distribution of Salmonella enterica in environmental waters and associated wildlife in two distinct watersheds, one in the Atlantic Coastal Plain (a high case rate rural area physiographic province and one in the Piedmont (a lower case rate rural area. Salmonella were isolated from the two regions and compared for serovar and strain diversity, as well as distribution, between the two study areas, using both a retrospective and prospective design. Thirty-seven unique serovars and 204 unique strain types were identified by pulsed-field gel electrophoresis (PFGE. Salmonella serovars Braenderup, Give, Hartford, and Muenchen were dominant in both watersheds. Two serovars, specifically S. Muenchen and S. Rubislaw, were consistently isolated from both systems, including water and small mammals. Conversely, 24 serovars tended to be site-specific (64.8%, n = 37. Compared to the other Salmonella serovars isolated from these sites, S. Muenchen and S. Rubislaw exhibited significant genetic diversity. Among a subset of PFGE patterns, approximately half of the environmental strain types matched entries in the USA PulseNet database of human cases. Ninety percent of S. Muenchen strains from the Little River basin (the high case rate area matched PFGE entries in PulseNet compared to 33.33% of S. Muenchen strains from the North Oconee River region (the lower case rate area. Underlying the diversity and turnover of Salmonella strains observed for these two watersheds is the persistence of specific Salmonella serovars and strain types that may be adapted to these watersheds and landscapes.

    The LHC experiments have developed very complex and powerful data distribution systems which provide detailed information on overall data distribution and usage. However, this covers the actual data usage only partially, since access from locally submitted jobs is not included. A set of tools has been developed at Bergische Universitaet Wuppertal and Ludwig-Maximilians-Universitaet Munich to fill this gap for sites which use dCache as the storage system. These tools also provide means to obtain filtered accounting information and reveal data access patterns which are not available in the standard dCache monitoring. We present the typical usage patterns for two Tier2 sites (BUW, LRZ) for the case of ATLAS but also other VOs active at BUW.

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

Salmonella, including 14 isolates of Salmonella serovar typhimurium and 19 isolates of Salmonella serovar muenchen, was subsequently isolated 47 times from 378 meat samples at the facility during a 13-mo period. Salmonella, including 26 isolates of S. serovar typhimurium, 10 of S. serovar muenchen, and 11 other serovars, also was isolated 54 times from 119 fecal samples. Only three plasmid profiles were identified in 59 S. typhimurium isolates from both meat and fecal samples. Although random-amplified polymorphic DNA fingerprinting using different primers in the polymerase chain reaction was able to distinguish between S. typhimurium and S. muenchen and to demonstrate similar chromosomal DNA fingerprints in some of the isolates from meat and feces, the results were not consistent enough to prove that the Salmonella in the feces originated from contaminated meat. However, the predominance of only two serovars in the meat fed to carnivores and in the feces of these animals suggests that the meat was the source of the Salmonella organisms in the feces.

    Ostrich (Struthio camelus) chicks less than 3 mo age are observed to experience a high mortality rate that is often associated with enteritis. This study was undertaken to investigate the infectious bacteria implicated in ostrich chick enteritis. Postmortems were performed on 122 ostrich chicks aged from 1 d to 3 mo and intestinal samples were subjected to bacterial culture. Bacterial isolates were typed by PCR and serotyping. Escherichia coli (E. coli; 49%) was the most frequently isolated from the samples followed by Clostridium perfringens (C. perfringens; 20%), Enterococcus spp. (16%), and Salmonella spp. (7%). Of the E. coli, 39% were categorized as enteropathogenic E. coli, 4% enterotoxigenic E. coli, and no enterohaemorrhagic E. coli were found. The majority (93%) of C. perfringens was Type A and only 7% was Type E. C. perfringens Types B through D were not present. The netB gene that encodes NetB toxin was identified from 16% of the C. perfringens isolated. All the C. perfringens Type E harbored the netB gene and just 10% of the C. perfringens Type A had this gene. Three Salmonella serotypes were identified: Salmonella Muenchen (S. Muenchen; 80%), S. Hayindongo (13%), and S. Othmarschen (7%). The indication is that the cause of enteritis in ostrich chicks is bacterial-involving: enteropathogenic E. coli and enterotoxigenic E. coli; C. perfringens Types A and E (with the possible influence of netB gene); and S. Muenchen, S. Hayindongo, and S. Othmarschen.

    The well-founded determination of the dioxin and furan emission (PXDD/PXDF) of road traffic was the aim of a research project jointly conducted by the Chair of Ecological Chemistry and Geochemistry at the University of Bayreuth (Prof. Hutzinger), the Institute for Organic Chemistry at the University of Tuebingen (Prof. Hagenmaier) and the IVK (Prof. Essers). The non-standardised examinations of an otto engine, a passenger car and a truck diesel engine required the development of sample-taking and analysis methods as well as of engine test technology. The otto engine driven with leaded gasoline containing scavengers showed the highest dioxin and furan emission while, on the other hand, the otto engine driven with unleaded gasoline, the diesel engines and in particular the otto engine with three-way catalytic converter showed much lower values. (orig.) [Deutsch] Die fundierte Ermittlung der Dioxin- und Furan-Emissionen (PXDD/PXDF) des Strassenverkehrs war das Ziel eines vom Lehrstuhl fuer Oekologische Chemie und Geochemie der Universitaet Bayreuth, dem Institut fuer Organische Chemie der Universitaet Tuebingen und dem IVK der Universitaet Stuttgart gemeinsam bearbeiteten Forschungsprojekts. Die nicht standardisierten Untersuchungen an einem Ottomotor, einem Pkw- und einem Lkw-Dieselmotor erforderten die Entwicklung von Probenahme- und Analyseverfahren sowie der motorischen Prueftechnik. Der mit verbleitem, scavengerhaltigem Benzin betriebene Ottomotor wies die hoechsten Dioxin- und Furanemissionen auf. Demgegenueber waren die Emissionen des mit unverbleitem Benzin betriebenen Ottomotors, der Dieselmotoren und besonders des Ottomotors mit Drei-Wege-Katalysator deutlich geringer. (orig.)

    Salmonella enterica infections are transmitted not only by animal-derived foods but also by vegetables, fruits, and other plant products. To clarify links between Salmonella serotypes and specific foods, we examined the diversity and predominance of food commodities implicated in outbreaks of salmonellosis during 1998-2008. More than 80% of outbreaks caused by serotypes Enteritidis, Heidelberg, and Hadar were attributed to eggs or poultry, whereas >50% of outbreaks caused by serotypes Javiana, Litchfield, Mbandaka, Muenchen, Poona, and Senftenberg were attributed to plant commodities. Serotypes Typhimurium and Newport were associated with a wide variety of food commodities. Knowledge about these associations can help guide outbreak investigations and control measures.

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

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

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

    With a resolution of 3 keV, the two lowest 0- states in 208Pb are identified by measurements of the reaction 207Pb(d, p) with the Muenchen Q3D magnetic spectrograph in a region where the average level spacing is 6 keV. Precise relative spectroscopic factors are determined. Matrix elements of the residual interaction among one-particle one-hole configurations in a two-level scheme are derived for the two lowest 0- states in 208Pb. The off-diagonal mixing strength is determined as 105 +-10(experimental) +-40(systematic) keV. Measurements of the reaction 208Pb(p,p') via isobaric analog resonances in 209Bi support the structure information obtained.

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

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

    Technology offers manifold possibilities for reducing CO{sub 2} emissions from private homes, but emissions from those sources continue to rise. One reason is that application of available technology is slow, primarily due to insufficient technical know-how and information, and poor market transparency. A project funded by the Deutsche Forschungsgemeinschaft now identified the factors promising successful implementation of relevant programmes to be launched for improvement of private home technology. The results are presented and discussed. (orig./CB) [Deutsch] Vielfaeltige technische Loesungen zur CO{sub 2}-Reduktion in privaten Haushalten sind hinlaenglich bekannt - trotzdem steigen die CO{sub 2}-Emissionen in diesem Bereich weiter an. Dies liegt an einem deutlichen Umsetzungsdefizit der technischen Moeglichkeiten, das insbesondere auf mangelnde technische Kenntnisse und fehlende Markttransparenz zurueckzufuehren ist. In einem von der Deutschen Forschungsgemeinschaft finanzierten Projekt wurden Erfolgsfaktoren entsprechender Programme fuer private Haushalte ermittelt.

    Five pre-enrichment methods were evaluated for effectiveness with the U.S. Food and Drug Administration's Bacteriological Analytical Manual Salmonella culture method in recovering S. Stanley, S. Poona, and S. Muenchen from artificially contaminated alfalfa seeds, and S. Saintpaul, S. Anatum, and S. Infantis from artificially contaminated mung bean seeds. The methods included: (1) Soak.--Test portions were inoculated into pre-enrichment media; (2) Rinse.--Test portions were rinsed with pre-enrichment media, and the media was decanted from the test portions; (3) Rinsed seed.--Pre-enrichment media was added to the test portions that were rinsed in the rinse method; (4) Wet blend.--Test portions were blended with the pre-enrichment media; and (5) Dry blend.--Test portions were blended prior to pre-enrichment. The methods of pre-enrichment were also evaluated for effectiveness in recovering Pantoea agglomerans from alfalfa and mung bean seeds with a modified culture method for the recovery of Enterobacteriaceae from foods. The purpose of these studies was to provide a model for the recovery of Salmonella that may occur in seeds as a natural contaminant. The relative effectiveness of the soak method was consistently superior to the rinse method in isolating the selected Salmonella serovars from both seed types. Statistically, the rinsed seed method was as effective as the soak method in all trials, except 1 of 3, with S. Muenchen and alfalfa seeds (P > 0.05). The relative effectiveness of the methods in isolating P. agglomerans from alfalfa and mung bean seeds was similar to that observed with the artificially contaminated test portions. The soak method was consistently the most effective method and the rinse method was consistently the most ineffective method. The rinsed seed, wet blend, and dry blend methods were also as effective as the soak method in all 3 trials with each seed type (P > 0.05).

    For decades, the Reactor Simulation and Safety Group at Ruhr-Universitaet Bochum (RUB) contributes to nuclear safety by computer code validation and model development for nuclear safety analysis. Severe accident analysis codes are relevant tools for the understanding and the development of accident management measures. The accidents in the plants Three Mile Island (USA) in 1979 and Fukushima Daiichi (Japan) in 2011 influenced these research activities significantly due to the observed phenomena, such as molten core concrete interaction and hydrogen combustion. This paper gives a brief outline of recent research activities at RUB in the named fields, contributing to code preparation for plant applications. Simulations of the molten core concrete interaction tests CCI-2 and CCI-3 with ASTEC and the hydrogen combustion test Ix9 with COCOSYS are presented exemplarily. Additionally, the application on plants is demonstrated on chosen results of preliminary Fukushima calculations.

    The electromagnetic calorimeter (EMC) of the PANDA detector to be constructed at FAIR consists of lead tungstate (PWO) crystals, which have a temperature dependent light yield. To achieve the design energy resolution, the EMC must be operated at -25 {sup circle} C, where temperature fluctuations of at most 0.1 {sup circle} C are acceptable. This results in high demands on the precision and resolution of the temperature monitoring. Ultra-thin platinum resistance temperature detectors (RTDs) are needed to measure the temperature in the densely packed EMC. The RTDs are read out by the temperature and humidity monitoring system for PANDA (THMP). Both have been developed at Ruhr-Universitaet Bochum. Not only the RTDs, but also the readout electronics has to be calibrated individually to suffice the high demands. Both, the calibration procedure and improvements in the electronic read out system are presented.

Durch den gezielten Einsatz der Gebaeudeleit- und -systemtechnik wird ein energiesparender Betrieb insbesondere der Gebaeudebeheizung, der Lueftungsanlage sowie der Beleuchtung schon in der Planungsphase vorbereitet. Zusammenfassend laesst sich feststellen, dass das entwickelte Technikkonzept nach erfolgter Abstimmung mit den Nutzerbeduerfnissen geringste Energieverbraeuche bei sehr gutem Komfort bietet. (orig.)

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

    The report summarizes investigations of effective heat transport processes inside highly porous solid structures. These heat transport processes are of decisive importance for the pore burner technology developed at Erlangen-Nuremberg University. A test stand was set up for recording the two-dimensional temperature field of cross-flowed solid structures. [German] Der vorliegende Bericht fasst Arbeiten zusammen, die sich mit der Bestimmung effektiver Waermetransportvorgaenge im Inneren von hochporoesen Festkoerperstrukturen befassen. Diese Waermetransportvorgaenge sind entscheidend fuer die Vorteile der am Lehrstuhl fuer Stroemungsmechanik der Friedrich-Alexander-Universitaet Erlangen-Nuernberg entwickelten Porenbrennertechnologie. Um diese Vorteile besser zu nutzen und um diese neuartige Technologie weiter verbessern zu koennen, ist es erforderlich, dass die ablaufenden Waermetransportvorgaenge im Inneren von hochporoesen Strukturen im Detail verstanden werden. Zu diesem Zweck wurde ein Versuchsstand erstellt, mit dem das zweidimensionale Temperaturfeld von durchstroemten Festkoerperstrukturen erfasst werden kann. (orig.)

    Within the framework of a Ph.D. thesis at the Hermann-Rietschel-Institute, Technical University Berlin experimental and analytic studies for the ventilation with openable windows were made. The results describe the possibilities and limits for free ventilation by windows. They can be a basis for the decision to install an HVAC-System or not. With a special building design and reduced cooling loads the period of using the ventilation by windows can be extended. (orig.) [German] Im Rahmen einer Dissertation am Hermann-Rietschel-Institut der Technischen Universitaet Berlin wurden experimentelle und analytische Untersuchungen durchgefuehrt, um Moeglichkeiten und Grenzen der Fensterlueftung darzustellen.

    Localization of electromagnetic waves in random media received renewed interest in the last years. Recent ultrafast optical experiments indicate the existence of highly localized photon modes in a system of homogeneous, randomly distributed, vertically aligned ZnO nano-needles. In particular, hot spots in the spatial distribution of the second harmonic generation (SHG) were found. In this work, we discuss the optical near field, which we obtain from full 3D solutions of Maxwell's equations of a model system in time domain. The spatial distribution of the electric near-field and the squared electric near-field intensity are investigated with statistical methods. The results are compared to the experimental findings. We thank Manfred Maschek, Slawa Schmidt, Martin Silies and Christoph Lienau from the Carl von Ossietzky Universitaet Oldenburg as well as Takashi Yatsui, Kokoro Kitamura and Motoichi Ohtsu from the University of Tokyo for sharing their experimental data with us prior to publication.

    This paper reports the first step in the development of a tactile array suitable for the presentation of haptic information in virtual reality. The system is based on the electric field dependence of the viscosity of electrorheological fluids. The simulation, as well as the experimental realization of single tactels is described. The mathematical approach is based on the Eckart model (Eckart W 2000 Continuum Mech. Thermodyn. 12 341-62) and its validity is demonstrated by comparing the resulting yield stress with the experimental results from Wunderlich (2000 Dissertation Universitaet Erlangen-Nuernberg). Two different tactel designs are realized and the experimental results are compared with numerical simulation. The design of modification B is shown to be applicable for the realization of an actuator array with high spatial resolution.

    Walter-Matsui, R.; Seipp, M.

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

    2002-01-01

    We investigate the method of an indirect detection of a MCP charge avalanche projected onto a resistive layer (G. Battistoni, et al., Nucl. Instr. and Meth., 202 (1982) 459). If the sheet resistance is favourable one can detect the charge cloud by the capacitive coupling to an anode structure a few millimetres behind the layer. The anode structure can be, for example, a wedge-and-strip electrode pattern (M. Unverzagt, Diplomarbeit, Universitaet Frankfurt 1992, private communication) as it is used for directly collecting the electron avalanche from a MCP. Detection of the induced charge is beneficial in several respects. Firstly, image distortions produced by secondary electron mediated charge redistribution are eliminated. Secondly, the noise component due to quantized charge collection, commonly referred to as partition noise, is not present. In addition, the dielectric substrate can function both as an element of the vacuum enclosure and HV insulator, making the electrical connections easily accessible and ...

  10. Precision gamma-ray polarimetry applied to studies of bremsstrahlung produced by polarized electrons

    2015-12-16

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

    In FASIMA II, the Institute for Machine Elements at the University of Stuttgart has a tool available which makes possible the examination of complex drive unit configurations. The examination of a vehicle of the compact class is introduced as an example of an application. The mass-production variant of the vehicle with a 5 speed manual gearbox was compared with two hybrid variants and a variant with a continuous variable transmission instead of the standard gearbox. It was found that hybrid drives do not necessarily lead to fuel savings. (orig.)
