    This report comprises six single lectures given at an information meeting organized by the Institut fuer Reaktortechnik der Technischen Hochschule Darmstadt (IRT) in Darmstadt on April 24, 1978. The lectures are an account of work performed at IRT on the mechanics of fuel pins and fuel elements and supported by the Fast Breeder Project (PSB) of KfK. These activities can be broken down into studies of the integral fuel pin (URANUS computer code) and into multidimensional studies of the fuel pin using the finite-element method (FINEL and ZIDRIG computer codes). Moreover, a report is presented of the status of the test facility for simulation of out-of-pile cladding tube loads and of the IRT project on the simulation and analysis of radiation damage.

    Right to left: Thomas Wobmann and Markus Zemp visit the LHC tunnel at CERN with G nther Dissertori and Marcel Wyler of ETH Zurich. Their visit was part of the top prize for a competition organised by the ETH department of physics to coincide with its open day in June. Residents of Zurich and surrounding Swiss cantons were invited to answer five physics questions broadcast on local radio and the Internet the week before the open day. The two winners' reward for knowing who did not believe that God plays dice, among other things, was a flight offered by Swiss International Air Lines to Geneva and a VIP tour of CERN. One highlight was a trip to the underground site of the future CMS experiment, where the scale of the enormous cavern makes construction machines look like children's toys.

    1988-01-01

    Electron paramagnetic resonance (EPR)spectrum of hemoglobin Zurich, after oxidation, storage and heating, showed several absorption derives in the high field region (g ≅ 2) which are indicative of hemichrome formation. Characteristic visible spectra of hemichromes were observed for oxidized Hb Zurich and for its spontaneous precipitate. The proportional increase of EPR signals at g ≅ 2 and decrease at g = 6.37, the constant ratio of absorbance at 540 nm to 280 nm during heating, and the similarity of this ratio for spontaneously precipitated HbA and for Hb Zurich indicate that heme is not lost during the first steps of Hb Zurich denaturation.

    Full Text Available [english] October 2009 the first state-funded University of Applied Sciences referring the fields public health, therapeutics and occupational medicine, the “Hochschule für Gesundheit hsg”, was founded in the City of , North Rhine-Westfalia. The study of health care/nursing, physical therapy, ergotherapy, logopedics and midwifery puts emphasis on an academic training for improving healthcare and therapeutics in German hospitals, medical offices and home care. Therefore a library had to be established which offers both practical text and specialist books and electronic resources and research material such as special research databases and journals. Temporarily located in only three rooms the library started setting up these electronic services within an e-learning environment and providing students and teachers with the important print material. The library also developed an integrated concept of functions and services, a “library development plan”, to ensure that a strategic process for elaborating the services is initialized in addition to the daily performance of improvisation skills. As to the establishment of a high level subject and usage related collection, media concept etc. the librarian in this new combined field of health and therapeutics finds himself in an unknown territory. There are no completely fitting statistics or models of other libraries to lean on. But by evaluating the usage of the offered media and services and observing developments in health sciences and its information market within a testing period the “canon” will be identified.In 2014 the library will be one of the main attractions on the “Health Campus Bochum” where the university and cooperating health research institutes, health administration and health care companies will be situated. Therefore the new library area in the second floor of a new building has to be planned involving the topics library workflows, circulation by RFID, shelving

    Tens of thousands of tonnes of cyclic volatile methylsiloxanes (cVMS) are used each year globally, which leads to high and continuous cVMS emissions to air. However, field measurements of cVMS in air and empirical information about emission rates to air are still limited. Here we present measurements of decamethylcyclopentasiloxane (D5) and dodecamethylcyclohexasiloxane (D6) in air for Zurich, Switzerland. The measurements were performed in January and February 2011 over a period of eight days and at two sites (city center and background) with a temporal resolution of 6-12 h. Concentrations of D5 and D6 are higher in the center of Zurich and range from 100 to 650 ng m(-3) and from 10 to 79 ng m(-3), respectively. These values are among the highest levels of D5 and D6 reported in the literature. In a second step, we used a multimedia environmental fate model parametrized for the region of Zurich to interpret the levels and time trends in the cVMS concentrations and to back-calculate the emission rates of D5 and D6 from the city of Zurich. The average emission rates obtained for D5 and D6 are 120 kg d(-1) and 14 kg d(-1), respectively, which corresponds to per-capita emissions of 310 mg capita(-1) d(-1) for D5 and 36 mg capita(-1) d(-1) for D6.

    2017-03-01

    During the poliomyelitis epidemics of the last century hospitals were inundated with patients in acute respiratory failure. Between 1946 and 1949, Nandor (Ferdinand) Eichel documented the use of the iron lung in children with acute poliomyelitis at the University Children's Hospital, Zurich. The aim was to assess the effectiveness of the Iron lung and negative pressure respiratory support for this indication and to establish its role in the context of other existing therapies at the time. Eichel produced his review and data as the Inaugural Dissertation towards his medical degree from the the University of Zurich, published in 1951. The dissertation was written in German and first translated into English in 2014. The current paper explores the findings of the dissertation and explains why there has been the transition to techniques of respiratory support today. It includes a biography of Dr F. N. Eichel and an update on the current status of poliomyelitis. The original dissertation was found in the home of Nandor's son and was of great interest to the current authors, Nandor's granddaughter and her colleague.

  9. The Physikalisch-Technische Reichsanstalt. Its importance in the development of modern physics

    2011-01-01

    The history of the Physikalische-Technische Bundesanstalt (PTB) and its predecessor institution, the Physikalisch-Technische Reichsanstalt (PTR) reaches farly back - until the end of the 19th century - and covers by this large epochs of physics. Epochs, in which physics extended and designed powerful models for the description of the world. Physics extends and rendered precise thereby the description of the world always by two methodical ways: By theory and experiment, by calculation and by measurement. For the measurement with as high as possible accuracy stands today the PTB and stood earlier the PTR. So stand precision measurements of the blackbody radiation, which Ferdinand Kurlbaum, Otto Lummer, and Ernst Pringsheim performed in the opticallaboratory of the earlier PTR, at the beginning of quantum mechanics. These measurement put the experimental base for Max Planck, who possessed in the year 1900 the revolutionary courage, to quantize radiation, and who so established his radiation laws. More beautifully the fruitful connection of precise measurement and theoretical model can be scarcely demonstrated. With such connections deals this book, in which the authors take a selection of scientific milestones of the PTR into view and mediate to the reader also by means of numerous original documents. The discovery of the Meissner effect in superconductors belongs here just so to this like the discovery of the element rhenium by Ida Tacke and Walter Noddack or the fundamental contributions of Hans Geiger, Walther Bothe, and Werner Kohlhoerster to the measurement of the radiation in the radioactive decay. And also Albert Einstein and his intensive relations to the Reichsanstalt are a theme of this book. His single physical experiment performed the great theorist Einstein with Wander Johannes de Haas in the PTR: Measurements on Amperes molecular-current hypothesis. The history of the PTR and the PTB is filled with such results of the ''measurement arts'' - results

Durch die Neugründung der staatlichen Hochschule Hamm-Lippstadt konnten in den dortigen Bibliotheken Informationskompetenz-Veranstaltungen grundlegend neu konzipiert und umgesetzt werden. Bei der Neugestaltung mussten unterschiedliche Kriterien zu Inhalten, Formaten, Zielgruppen etc. berücksichtigt werden. Hierbei spielten auch Überlegungen eine Rolle, wie Informationskompetenz an der HSHL definiert werden soll. Im vorliegenden Artikel werden die zu berücksichtigenden Kriterien für die Umsetzung von Informationskompetenz-Veranstaltungen an der HSHL erläutert. Des Weiteren wird ein Ausblick gewagt, wie diese Veranstaltungen weiter ausgebaut werden können. Lectures on information literacy are an important part of the work of a scientific library and are crucial for a successful university education. The founding of the state University of Applied Sciences Hamm-Lippstadt created the opportunity to develop a completely new series of information literacy lectures. During the creation of this lecture series, different criteria such as content, format, target groups and others had to be considered. It was also a part of this process to specify how the term information literacy should be defined for the University of Applied Sciences Hamm Lippstadt. This article discusses the criteria applied to the implementation and also gives an outlook on possible further developments.

    Individuals with severe mental illness frequently have difficulties in obtaining and maintaining adequate accommodation. If they are not willing or able to adapt to requirements of traditional supported housing institutions they may live in sheltered and emergency accommodation. Adequate mental health services are rarely available in these facilities. The aim of the present study was to evaluate mental health, functional and social status of individuals living in community sheltered housing facilities. A cross-sectional survey of n=338 individuals in sheltered housing compared to a sample of patients at intake in acute inpatient psychiatry (n=619) concerning clinical and social variables was carried out in the catchment area of Zurich. Matched subsamples of individuals with schizophrenia (n=168) were compared concerning functioning and impairments on the Health of the Nation Outcome Scales (HoNOS). Individuals with schizophrenia in sheltered housing (25% of the residents) have significantly more problems concerning substance use, physical illness, psychopathological symptoms other than psychosis and depression, and relationships, daily activities and occupation than patients with schizophrenia at intake on an acute psychiatric ward. Community sheltered accommodation although conceptualized to prevent homelessness in the general population de facto serve as housing facilities for individuals with schizophrenia and other severe mental illness.

    Friedrich, Verena; Brügger, Adrian; Bauer, Georg

    2009-01-01

    This study provides information about the prevalence of tobacco prevention (TP) and the stages of change with respect to the introduction of TP among companies in the Canton of Zurich (n = 1,648). It explores the factors that predict restrictiveness of smoking policies, number of individual support measures, interest in services to promote TP, and the relationship between TP and health outcomes. Data were gathered by means of a written questionnaire and analysed using ordinal regression models. Whereas many companies maintain smoke-free policies, only few provide cessation-courses. Health and welfare organisations have strictest, and building and hospitality companies have least strict policies. Company size predicts number of individual support measures but not policy restrictiveness. Both measures are predicted by personal concern of the representative. Interest in services is predicted by tobacco-related problems and medium stages of change. Finally, stricter policies are associated with lower proportion of smokers and less tobacco-related problems. Health professionals should support less advanced companies in their endeavour to implement TP. The findings provide a baseline to evaluate the implementation of the forthcoming smoke-free legislation.

    The research on the life and teaching of Theophrastus of Hohenheim (1493/94-1541), called Paracelsus, offers a broad variety of problems still to be solved. In comparison to being well-known and having written the most voluminous 16th century professional literature next to Luther, the scientific edition of his works remains badly neglected. About a quarter of them, mostly theological ones, are widely scattered around the world in manuscript form and still await their edition. The ones being already edited lack the critical apparatus satisfying modern standards, including a dictionary for the specific Paracelsian expressions and a general index. The Zurich Paracelsus Project now offers a possible way to manage the problems. Microfilms of important manuscripts will be collected and united at a central place. The mass of the edited texts will be electronically recorded and analysed according to various criteria. On the basis of these preparatory work an index will be produced and building stones for a Paracelsus dictionary will be made available. A homepage (http:/(/)www.mhiz.unizh.ch/Paracelsus.html++ +) will present the state of the art and will serve to coordinate further activities.

    The investigations of potential siting areas for a repository for high-level radioactive waste which are concentrated in the crystalline basement of Northern Switzerland have been expanded since the late 1980s to include suitable sedimentary units. After extensive desk study evaluation, the approximately 100 m thick Opalinus Clay of the Tabular Jura east of the Aare river was chosen as the most promising sedimentary option. In this area not only the Opalinus Clay but also the over- and underlying units are clay-rich, in contrast to the tabular Jura west of the Aare river. In the area North of Laegeren - Zurich Weinland, where the Opalinus Clay is situated in the optimum depth range of 400 to 1000 m below surface, approximately 220 km of new high-resolution seismic profiles were recorded and interpreted together with existing seismic lines. Due to thorough field work and data processing, a very good quality of seismic lines was obtained. This allowed precise mapping of the marker horizons in general and the Opalinus Clay in detail. The goal of this study was to determine and delineate the most important tectonic units as well as to describe the potential host rocks in these units. By way of interactive interpretation of all available seismic lines, borehole data and surface data from the investigation area, depth maps of the most prominent marker horizons have been calculated and geological cross-sections constructed along the new seismic lines. The regional seismic character of the Middle Mesozoic units was modelled using borehole data from Weiach and Herdern. From this model the thickness of the Opalinus Clay along the new seismic lines was determined. The results indicate a relatively constant thickness of 95 to 120 m in the investigation area.

    The University Hospital of Zurich offers a text-based, Medical Online Consultation Service to the public since 1999. Users asked health questions anonymously to tele-doctors. This study focused on the characteristics of male enquirers with intimate health problems, the content of their questions, the medical advice given by tele-doctors and the rating of the service to prove the benefit of an online service for medical laymen. This retrospective study included 5.1% of 3,305 enquiries from 2008 to 2010 using the International Classification of Diseases-10 and International Classification of Primary Care codes relevant for intimate and sexual health problems in men. A professional text analysis program (MAXQDA) supported the content analysis, which is based on the procedure of inductive category development described by Mayring. The average age was 40 years, 63.1% enquirers had no comorbidity, in 62.5% it was the first time they consulted a doctor, and 70.2% asked for a specific, single, intimate health issue. In 64.3%, the most important organ of concern was the penis. Overall, 30.4% asked about sexually transmitted diseases. In 74.4% a doctor visit was recommended to clarify the health issue. The rating of the problem solving was very good. The service was mainly used by younger men without comorbidity and no previous contact with a doctor with regard to an intimate health problem. The anonymous setting of the teleconsultation provided men individual, professional medical advice and decision support. Teleconsultation is suggested to empower patients by developing more health literacy.

    Subaqueous landslides and their consequences, such as tsunamis, can cause serious damage to offshore infrastructure and coastal communities. Stability analyses of submerged slopes are therefore crucial, yet complex steps for hazard assessment, as many geotechnical and morphological factors need to be considered. Typically, deterministic models with data from a few sampling locations are used for the evaluation of slope stabilities, as high efforts are required to ensure high spatial data coverage. This study presents a simple but flexible approach for the probabilistic stability assessment of subaqueous slopes that takes into account the spatial variability of geotechnical data. The study area ( 2 km2) in Lake Zurich (northern Switzerland) shows three distinct subaquatic landslides with well-defined headscarps, translation areas (i.e. the zone where translational sliding occurred) and mass transport deposits. The ages of the landslides are known ( 2,210 and 640 cal. yr BP, and 1918 AD), and their triggers have been assigned to different mechanisms by previous studies. A combination of geophysical, geotechnical, and sedimentological methods served to analyse the subaquatic slope in great spatial detail: 3.5 kHz pinger seismic reflection data and a 300 kHz multibeam bathymetric dataset (1 m grid) were used for the detection of landslide features and for the layout of a coring and an in situ cone penetration testing campaign. The assignment of geotechnical data to lithological units enabled the construction of a sediment-mechanical stratigraphy that consists of four units, each with characteristic profiles of bulk density and shear strength. The thickness of each mechanical unit can be flexibly adapted to the local lithological unit thicknesses identified from sediment cores and seismic reflection profiles correlated to sediment cores. The sediment-mechanical stratigraphy was used as input for a Monte Carlo simulated limit-equilibrium model on an infinite slope for

    Full Text Available Abstract Background An extremely low level methicillin resistant Staphylococcus aureus (MRSA belonging to ST45, circulates among intravenous drug users in the Zurich area. This clone can be misinterpreted as an MSSA by phenotypic oxacillin resistance tests, although it carries a staphylococcal cassette chromosome mec (SCCmec element encoding a functional mecA gene and it produces PBP2a. Results This clone carried a new 45.7-kb element, termed SCCmecN1, containing a class B mec complex (mecA-ΔmecR1::IS1272, a truncated Tn4003 harbouring the dfrA gene, and a fusB1 gene, conferring methicillin, trimethoprim and low level fusidic acid resistance, respectively. In addition to the two insertion site sequences (ISS framing the SCCmec, a third ISS (ISS* was identified within the element. SCCmecN1 also harboured two distinct ccrAB complexes belonging to the class 4 subtype, both of which were shown to be active and to be able to excise the SCCmecN1 or parts thereof. Slight variations in the SmaI-PFGE pattern of the clinical MRSA isolates belonging to this clone were traced back to differences in the sizes of the SCCmec J2 regions and/or to a 6.4-kb deletion extending from ISS* to the right end ISS. This latter deletion led to a variant right SCCmec-chromosomal junction site. MRSA clones carrying the shorter SCCmec with the 6.4-kb deletion were usually ciprofloxacin resistant, while strains with the complete SCCmecN1 were co-trimoxazole resistant or had no additional resistances. This suggested that the genetic backbone of the host S. aureus, although identical by PFGE pattern, had at some stage diverged with one branch acquiring a sulfonomide resistance mutation and the other ciprofloxacin resistance. Conclusion This description of the structure and variations of SCCmecN1 will allow for quicker and easier molecular detection of this clone and monitoring of its spread.

    The demand for electrical energy kept rising until about ten year ago. Since then, increases is stagnating with only slight tendencies of rising. This does not apply to the demands for power supply quality. Any even short power cut could have severe economic and ecological consequences. Users, industry and legisators are therefore constantly attempting to raise the level of safety precautions i.e. stand-by-power stations (see. DIN-VDE 0100, 0107, 1018). Utility companies too pay heed to these demands by improving their technical facilities. Improvement of single components enables parallel grid operation of different stand-by facilities. (orig./KO) [Deutsch] Der Bedarf an elektrischer Energie ist bis vor ca. 10 Jahren stark angestiegen. Seither stagniert der Zuwachs bei nur leicht steigender Tendenz. Nicht so jedoch die Ansprueche an die Qualitaet der Stromversorgung. Ein Ausfall der Stromversorgung - auch nur fuer kurze Zeit - kann oekonomisch und oekologisch schlimme Folgen haben. Es ist daher nur verstaendlich, dass Nutzer, Industrie und Gesetzgeber sich bemuehlen, den Standard von Sicherheitsstromversorgungsanlagen stetig zu verbessern (s. hierzu DIN-VDE 0100, 0107, 0108). Auch die Energieversorgungsunternehmen tragen dem Rechnung durch angepasste technische Anschlussbedingungen (TAB). Durch Verbesserung von technischen Einzelkomponenten ist heute ein Netz-Parallelbetrieb verschiedener Sicherheitsstromversorgungsanlagen technisch leicht moeglich. (orig./KO)

    Poly- and perfluorinated alkyl substances (PFASs) are anthropogenic pollutants ubiquitously found in the environment. Volatile PFASs are likely transported atmospherically over long ranges, but identification and quantification of emission sources is a challenging task. In this work, special meteorological conditions were utilized to quantify atmospheric emissions of Zurich City, Switzerland with a dual approach of modeling and field measurements. During high pressure systems in summer, a stable nocturnal boundary layer is formed in which pollutants are enriched. For volatile PFASs, a diel pattern of high concentrations in the night and low concentrations during the day was observed in Zurich, which is likely due to the atmospheric boundary layer dynamics. These results enable to model the emission source strength of Zurich City with a multimedia mass balance model in an accompanying paper. Cluster analyses suggested that perfluorocarboxylates (PFCAs) are a result of degradation of volatile precursors and direct emissions. - Highlights: ► Atmospheric PFAS concentrations in Zurich increase during the night. ► Diel concentration dynamics are likely due to stable nocturnal boundary layer. ► City is a source of PFASs to the atmosphere. ► 8:2 FTOH concentrations are high: up to 1200 pg/m 3 . ► PFAA concentrations are correlated with ozone, not particulate matter. - Semivolatile PFAS concentrations follow a diel trend in Zurich City in stable summer conditions likely due to atmospheric boundary layer effects and urban emissions.

    Fluorotelomer alcohols (FTOHs) and perfluorooctane sulfonamides (FOSAs) are present in consumer products and are semi-volatile precursors of persistent perfluoroalkyl acids (PFAAs). The high variability of levels of FTOHs and FOSAs in products makes it difficult to derive FTOH- and FOSA-emissions from urban areas based on emission factors. Here we used a multimedia mass balance model that describes the day-night cycle of semi-volatile organic chemicals in air to interpret measurements of 8:2 FTOH, 10:2 FTOH, MeFOSA and EtFOSA from a sampling campaign in summer 2010 in Zurich, Switzerland. The estimated emission source strength of the four substances follows the sequence: 8:2 FTOH (2.6 g/h) > 10:2 FTOH (0.75 g/h) > MeFOSA (0.08 g/h) > EtFOSA (0.05 g/h). There is no FTOHs- or FOSAs-related industry in Zurich. Accordingly, our estimates are representative of diffusive emissions during use and disposal of consumer products, and describe noticeable sources of these PFASs to the environment.

    To evaluate whether cerclage wire or a lateral plate increases the peak-torque load to failure, compared to femora without adjunctive fixation, in femora implanted with Zurich Cementless stems. In vitro biomechanical study. Paired femora from adult dogs (n = 24) weighing 28-35 kg. Pairs of femora were implanted with a stem and randomly assigned to 2 treatment groups: cerclage or plate. Within each pair, either 3 loop cerclage wires or a laterally applied 12-hole Advanced Locking Plate System 10-mm plate (ALPS 10) were implanted in a femur, whereas the contralateral femur acted as control with no adjunctive fixation. After application of a static axial load each specimen was loaded to failure in torsion. Peak torque load at failure was compared between femora with each adjunctive fixation and the control using a paired t-test; P plated group (P plates and with cerclage were 13.9% and 7.2% stronger in torsion than the femora without fixation, respectively. Adjunctive fixation with a laterally applied ALPS 10 may aid in the prevention of peri-prosthetic fractures associated with Zurich Cementless medium stems. © Copyright 2013 by The American College of Veterinary Surgeons.

    There are two approaches in the research on the relation between social conditions and mental disorder: The ecological approach is concerned with characteristics of the social composition of a certain geographical area and their relation to the frequency of disorders, whereas for the individualistic view variables of the psychosocial background of the individual are of interest. This study is on the risk for psychiatric admission (first and re-admission). While considering variables of the social context of the community as well as of the background of the individual, it tries to take into account both the ecological and the individualistic view of the relationship between social conditions and (treated) mental disorder. The sample of the study includes data of 4021 psychiatric inpatients treated in 1997 in one of the seven psychiatric hospitals of the Swiss canton of Zurich as well as data of social context of the 171 communities of the canton of Zurich. The psychiatric first and re-admission rates of the community can be predicted by the following variables of its social context: 1. pro portion of foreigners, 2. urban character of the living area, 3. population density. Two other variables are of relevance only for the prediction of first admissions: 4. proportion of one-person households and 5. local tax rate. However, further results of the study show that correlations between variables of the social context and psychiatric admission rate of the community cannot be interpreted as risks for the individual.

    We have developed a haptic-based approach for retraining of interjoint coordination following stroke called time-independent functional training (TIFT) and implemented this mode in the ARMin III robotic exoskeleton. The ARMin III robot was developed by Drs. Robert Riener and Tobias Nef at the Swiss Federal Institute of Technology Zurich (Eidgenossische Technische Hochschule Zurich, or ETH Zurich), in Zurich, Switzerland. In the TIFT mode, the robot maintains arm movements within the proper kinematic trajectory via haptic walls at each joint. These arm movements focus training of interjoint coordination with highly intuitive real-time feedback of performance; arm movements advance within the trajectory only if their movement coordination is correct. In initial testing, 37 nondisabled subjects received a single session of learning of a complex pattern. Subjects were randomized to TIFT or visual demonstration or moved along with the robot as it moved though the pattern (time-dependent [TD] training). We examined visual demonstration to separate the effects of action observation on motor learning from the effects of the two haptic guidance methods. During these training trials, TIFT subjects reduced error and interaction forces between the robot and arm, while TD subject performance did not change. All groups showed significant learning of the trajectory during unassisted recall trials, but we observed no difference in learning between groups, possibly because this learning task is dominated by vision. Further testing in stroke populations is warranted.

    The 'Solgreen Kraftwerk 1' PV plant was built in Zurich, in June 2001. The Solgreen system optimizes the integration of photovoltaic modules on green flat roofs by using the ground substrate in a double function for both; as soil substrate for the vegetation and as a foundation for the modules mounting structure. The project's main goal was to test the suitability of the Solgreen system. Furthermore, the interacting influences of the roof vegetation and the photovoltaic system were examined scientifically over a 5 year period by an external expert. 12 sample areas were covered with different substrates and different seeds were used on the roof during the test period. Ecosystem diversity amounted to 140 different breeds of plants as well as insects and animals. The modules led to a higher structural diversity on the roof by creating shaded areas and different water distribution. Saplings mainly growing in low vegetation density areas, caused shading on modules and had to be removed. Mulleins were an additional shading problem on one of the rooftops; leading to a measurable energy reduction. For future installations of this type, a low substrate height in front of the modules and seeds which produce low growing plants can reduce such shading problems. This photovoltaic system's technical performance was higher compared to the average system's performance in Zurich. Visual controls of the system showed almost no soiling of the PV modules, primarily due to the frameless modules, but maybe also due to the plants' air cleaning effect. (author)

    Hb Zurich-Albisrieden [HBA2: c.178G > C; α59(E8)Gly→Arg (α2)] is a rare nondeletional α-thalassemia (α-thal) that results from a nucleotide substitution at codon 59 of the α2-globin gene. In this report, we present a fetus with cardiomegaly, enlarged placenta and increased middle cerebral artery-peak systolic velocity (MCA-PSV) at 25 weeks' gestation. Fetal blood sampling revealed the severe anemia [hemoglobin (Hb) level being 5.5 g/dL] and Hb H (β4) disease-like hematological findings with Hb Bart's (γ4) level of 30.7%. Molecular analysis of the family found that the father was an Hb Zurich-Albisrieden carrier, the mother heterozygous for the - - SEA α 0 -thal deletion, and the fetus was a compound heterozygote for Hb Zurich-Albisrieden and the - - SEA α 0 -thal deletion. Therefore, this was a rare case of Hb Bart's hydrops fetalis associated with Hb Zurich Albisrieden.

    Full Text Available The Sihl River flows through Zurich, Switzerland's most populated city, for which it represents the largest flood threat. To anticipate extreme discharge events and provide decision support in case of flood risk, a hydrometeorological ensemble prediction system (HEPS was launched operationally in 2008. This model chain relies on limited-area atmospheric forecasts provided by the deterministic model COSMO-7 and the probabilistic model COSMO-LEPS. These atmospheric forecasts are used to force a semi-distributed hydrological model (PREVAH, coupled to a hydraulic model (FLORIS. The resulting hydrological forecasts are eventually communicated to the stakeholders involved in the Sihl discharge management. This fully operational setting provides a real framework with which to compare the potential of deterministic and probabilistic discharge forecasts for flood mitigation.

    To study the suitability of HEPS for small-scale basins and to quantify the added-value conveyed by the probability information, a reforecast was made for the period June 2007 to December 2009 for the Sihl catchment (336 km2. Several metrics support the conclusion that the performance gain can be of up to 2 days lead time for the catchment considered. Brier skill scores show that overall COSMO-LEPS-based hydrological forecasts outperforms their COSMO-7-based counterparts for all the lead times and event intensities considered. The small size of the Sihl catchment does not prevent skillful discharge forecasts, but makes them particularly dependent on correct precipitation forecasts, as shown by comparisons with a reference run driven by observed meteorological parameters. Our evaluation stresses that the capacity of the model to provide confident and reliable mid-term probability forecasts for high discharges is limited. The two most intense events of the study period are investigated utilising a novel graphical representation of probability forecasts, and are used

    There is a growing trend towards using calculation programmes to design and optimise technical systems. Such programmes simulate the systems' dynamic behaviour on the basis of mathematical models. This book first presents the methods used for model identification and model description. A widely applicable basic algorithm has been derived by means of these methods. Creating an overview block diagram of the system under study constitutes an important step of model development. The methods elaborated by the author are applied to numerous examples ordered in a sequence of growing complexity and hence difficulty. The examples each end with calculations on the model's behaviour, the results of which the reader can verify. Using the applied basic algorithm as a basis the reader can efficiently examine other systems not addressed in the book. [German] Technische Systeme werden immer staerker mit Hilfe von Rechnerprogrammen entworfen und optimiert. Die Programme simulieren das dynamische Verhalten der Systeme auf der Basis von mathematischen Modellen.

Eine wichtige Stufe der Modellentwicklung ist das Gesamt-Blockschaltbild des untersuchten Systems. Die vom Autor erarbeitete Methodik wird auf zahlreiche Beispiele wachsender Komplexitaet und damit wachsenden Schwierigkeitsgrades angewendet. Diese Beispiele enden mit Berechnungen des Verhaltens dieser Modelle, deren Ergebnisse der Leser nachpruefen kann. Der Leser kann auf der Grundlage des angewendeten Grundalgorithmus zielstrebig andere, im Buch nicht behandelte, Systeme untersuchen. (orig.)

    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.)

    Full Text Available An Alaskan Malamute (2-year-old, castrated male, 41kg was referred with bilateral hind limb lameness. The dog had a history of a bilateral triple pelvic osteotomy (TPO to correct hip dysplasia one year previously, a surgery that was unsuccessful. On physical examination, pain and crepitus were noted in both hip joints. There was hip joint subluxation and mild degenerative changes bilaterally seen by radiograph. A Zurich cementless total hip replacement (ZCTHR was planned for the right hind limb. After a craniolateral approach, an acetabular cup and a cementless femoral stem were implanted. The femoral head was placed in the femoral stem, and the prosthetic joint was then reduced. At a 9 month postoperative checkup, there was no pain on palpation or manipulation of the right pelvic limb, and the range of motion was within normal limits. On radiological examination, there was no implant loosening. The ZCTHR can thus be applied in a failed TPO patient as a revision surgery.

    1996-01-01

    Contact centres for drug addicts in the city of Zurich exist since 1988 to provide decentralized low threshold meeting places and contact centres for persons who are poor and neglected. The main objective of these survival aids is to counteract further impoverishment of the addicted in order to actively contribute to their subsistence. Since its foundation the project as a whole has been submitted to numerous structural changes which had to be taken into consideration by the evaluation. Subject of the examination was the description of the target group and the staff, the use of the services and their effect on the users as well as the environment. Only quantitative methods were used. The target group of the centers consisted of drug consumers who at the best are partially socially integrated, but usually completely desintegrated. The evaluation revealed that the different contact centers services were extensively used and met the focal needs of their users. However, the high fluctuation of personnel within the project teams turned out to be a permanent problem for the project management and the operators. As main reasons for the fluctuation the authors discuss the great dependency on political decisions and the problematical demanding clientele. Due to these structural turbulences some staff related offers are only accepted to a limited degree, and the contact centers tend to become simple supply services. Therefore the authors endorse the redefinition of long term objectives of the institution under consideration of the necessary framework.

    The aims of this paper are to describe the incidence trends of invasive cutaneous melanoma in the Canton of Zurich and to evaluate clinical and pathological factors such as cancer subtype, localization, age and Breslow thickness. A retrospective analysis was carried out with data from the population-based Cancer Registry of Zurich and Zug located in Zurich. A total of 8469 cases in 8034 different patients of invasive cutaneous melanoma were registered for the period 1980-2010 in the Canton of Zurich. Incidence trends were age standardized to the European standard population. Joinpoint regression was used to compute changes in incidence and mortality rates, measured as the annual percent change (APC). The most common subtypes of cutaneous melanoma were superficial spreading melanoma (SSM, 41.1%), followed by nodular melanoma (16.5%), lentigo maligna melanoma (13.5%), acral-lentiginous melanoma (5.0%) and other types of melanoma (2.8%); 21.1% were melanoma not otherwise specified. The trunk was the most frequent location (30.8%), followed by the lower limb and hip (26.4%) and the upper limb and shoulder (22.8%). Statistically significantly increasing incidence trends were observed for both men (APC=3.0%) and women (APC=2.1%). Incidences of SSM and melanoma not otherwise specified were the histological subtypes for which a significant increase in incidence was observed (APC for the period 1980-2010=3.2% for both). In terms of Breslow thickness, thin melanomas (0.01-1.00 mm) showed an increasing incidence. The incidence of melanoma increased in both men and women between 1980 and 2010. In terms of the different subtypes and Breslow thickness, increasing incidences of the SSM and of thin melanomas (0.01-1.00 mm) were observed. These observations are in agreement with other studies from Southern and Western Switzerland as well as other European countries and the USA.

    2006-01-01

    In 1894 Gottlieb Hägi, a former guard at the mental institution Burghölzli in Zurich, published a brochure in which he heavily critizised the conditions in the asylum, its management, the board of supervision and the responsible authorities. This report attracted great public notice and led to an extended investigation. With the example of the "case Hägi", the present work analyzes the position of critics and defendors of mental institutions and studies the roles played by the government and the authorities in this area of conflict. Beyond this particular debate, the reaction of government and authorities at critics of the psychiatry of mental institutions after the "case Hägi" is investigated by an analysis of the complaints procedures against the psychiatric institutions of the canton Zurich which were initiated between 1870 and 1970. It is concluded that in complaint procedures a tight connection existed between authorities and psychiatry. In case of conflicts, the mental institutions could count on the support of the government and this played an important role for legitimating psychiatry.

    Boehm, Alexandria B

    2002-10-15

    In this study, we extend the established scaling theory for cluster size distributions generated during unsteady coagulation to number-flux distributions that arise during steady-state coagulation and settling in an unmixed water mass. The scaling theory predicts self-similar number-flux distributions and power-law decay of total number flux with depth. The shape of the number-flux distributions and the power-law exponent describing the decay of the total number flux are shown to depend on the homogeneity and small i/j limit of the coagulation kernel and the exponent kappa, which describes the variation in settling velocity with cluster volume. Particle field measurements from Lake Zurich, collected by U. Weilenmann and co-workers (Limnol. Oceanogr.34, 1 (1989)), are used to illustrate how the scaling predictions can be applied to a natural system. This effort indicates that within the mid-depth region of Lake Zurich, clusters of the same size preferentially interact and large clusters react with one another more quickly than small ones, indicative of clusters coagulating in a reaction-limited regime.

    Two PhD theses (Alexander Gordienko, 1912; Johannes Angerstein, 1914) and a dissertation in partial fulfillment of a PhD thesis (H. S. French, Zurich, 1914) are reviewed that deal with hitherto unpublished UV-vis spectroscopy work of coordination compounds in the group of Alfred Werner. The method of measurement of UV-vis spectra at Alfred Werner's time is described in detail. Examples of spectra of complexes are given, which were partly interpreted in terms of structure (cis ↔ trans configuration, counting number of bands for structural relationships, and shift of general spectral features by consecutive replacement of ligands). A more complete interpretation of spectra was hampered at Alfred Werner's time by the lack of a light absorption theory and a correct theory of electron excitation, and the lack of a ligand field theory for coordination compounds. The experimentally difficult data acquisitions and the difficult spectral interpretations might have been reasons why this method did not experience a breakthrough in Alfred Werner's group to play a more prominent role as an important analytical method. Nevertheless the application of UV-vis spectroscopy on coordination compounds was unique and novel, and witnesses Alfred Werner's great aptitude and keenness to always try and go beyond conventional practice.

    This final report for the Swiss Federal Office of Energy (SFOE) describes the results obtained from the monitoring of a photovoltaic (PV) installation that was installed on the roof and facade of a gym at the Stadelhofen High School in the city of Zurich, Switzerland. This prize-winning installation features multi-functional PV modules, whose solar cells are mounted on double-glazed roof windows as well as further laminated facade modules that provide both power and shading. The report gives details of the results obtained from measurements made on the PV installations and includes the results of laboratory measurements made on selected modules. The performance of the installation, which started operation in 1999, was monitored until 2001. The report presents the results of the monitoring campaign, that not only monitored power output and energy production but also cell temperatures. These can rise up to 85 {sup o}C in summer and lead to power losses of around 7%. The self-cleaning properties of roof, which is only lightly sloped, are also commented on by the report.

    Interest in subtypes of mental disorders is growing in parallel with continuing research progress in psychiatry. The aim of this study was to examine pure animal phobia in contrast to other specific phobias and a mixed subtype. Data from three representative Swiss community samples were analysed: PsyCoLaus (n = 3720), the ZInEP Epidemiology Survey (n = 1500) and the Zurich Study (n = 591). Pure animal phobia and mixed animal/other specific phobias consistently displayed a low age at onset of first symptoms (8-12 years) and clear preponderance of females (OR > 3). Meanwhile, other specific phobias started up to 10 years later and displayed almost a balanced sex ratio. Pure animal phobia showed no associations with any included risk factors and comorbid disorders, in contrast to numerous associations found in the mixed subtype and in other specific phobias. Across the whole range of epidemiological parameters examined in three different samples, pure animal phobia seems to represent a different entity compared to other specific phobias. The etiopathogenetic mechanisms and risk factors associated with pure animal phobias appear less clear than ever.

    Full Text Available Syphilis is considered as one of the most devastating sexually transmitted diseases in human history. Based on historical records, the (German for spread through Europe after 1495 and shared symptoms with what we know today as syphilis. Many cities took measures to protect their population. Here, transliterations of archival documents from the 15 and 16 century (provided in the appendix are used to trace the steps taken by the governing authorities in Zurich to deal with this emerging infectious disease. One of the central measures taken by the city was to establish a quarantine facility referred to as the The city doctors, including the well-known physician and naturalist Conrad Gessner, oversaw the obligatory quarantine and treatment of patients with symptoms. Treatment could range from better nutrition, herbal remedies and skin ointments to aggressive heat therapy and “smoking”. Furthermore, the affliction was suspected as a sexually acquired disease, hence prostitutes and infected foreigners were extradited from the city. Meanwhile, the church used its social influence to promote a more “Christian” behavior. In several respects, the public health measures taken in the 16 century against a new and menacing epidemic do not diverge in their basic rationale from approaches used during the 20 century and today.

    Full Text Available Hourly measurements of 13 volatile hydrocarbons (C2–C7 were performed at an urban background site in Zurich (Switzerland in the years 1993–1994 and again in 2005–2006. For the separation of the volatile organic compounds by gas-chromatography (GC, an identical chromatographic column was used in both campaigns. Changes in hydrocarbon profiles and source strengths were recovered by positive matrix factorization (PMF. Eight and six factors could be related to hydrocarbon sources in 1993–1994 and in 2005–2006, respectively. The modeled source profiles were verified by hydrocarbon profiles reported in the literature. The source strengths were validated by independent measurements, such as inorganic trace gases (NOx, CO, SO2, methane (CH4, oxidized hydrocarbons (OVOCs and meteorological data (temperature, wind speed etc.. Our analysis suggests that the contribution of most hydrocarbon sources (i.e. road traffic, solvents use and wood burning decreased by a factor of about two to three between the early 1990s and 2005–2006. On the other hand, hydrocarbon losses from natural gas leakage remained at relatively constant levels (−20%. The estimated emission trends are in line with the results from different receptor-based approaches reported for other European cities. Their differences to national emission inventories are discussed.

  17. Advancement of the 10-species subgingival Zurich Biofilm model by examining different nutritional conditions and defining the structure of the in vitro biofilms

    Science.gov (United States)

    2012-01-01

    Background Periodontitis is caused by a highly complex consortium of bacteria that establishes as biofilms in subgingival pockets. It is a disease that occurs worldwide and its consequences are a major health concern. Investigations in situ are not possible and the bacterial community varies greatly between patients and even within different loci. Due to the high complexity of the consortium and the availability of samples, a clear definition of the pathogenic bacteria and their mechanisms of pathogenicity are still not available. In the current study we addressed the need of a defined model system by advancing our previously described subgingival biofilm model towards a bacterial composition that reflects the one observed in diseased sites of patients and analysed the structure of these biofilms. Results We further developed the growth media by systematic variation of key components resulting in improved stability and the firm establishment of spirochetes in the 10-species subgingival Zurich biofilm model. A high concentration of heat-inactivated human serum allowed the best proliferation of the used species. Therefore we further investigated these biofilms by analysing their structure by confocal laser scanning microscopy following fluorescence in situ hybridisation. The species showed mutual interactions as expected from other studies. The abundances of all organisms present in this model were determined by microscopic counting following species-specific identification by both fluorescence in situ hybridisation and immunofluorescence. The newly integrated treponemes were the most abundant organisms. Conclusions The use of 50% of heat-inactivated human serum used in the improved growth medium resulted in significantly thicker and more stable biofilms, and the quantitative representation of the used species represents the in vivo community of periodontitis patients much closer than in biofilms grown in the two media with less or no human serum.

The abundances of all organisms present in this model were determined by microscopic counting following species-specific identification by both fluorescence in situ hybridisation and immunofluorescence. The newly integrated treponemes were the most abundant organisms. Conclusions The use of 50% of heat-inactivated human serum used in the improved growth medium resulted in significantly thicker and more stable biofilms, and the quantitative representation of the used species represents the in vivo community of periodontitis patients much closer than in biofilms grown in the two media with less or no

    During the last decades, autopsy rates have dramatically decreased in many countries. The Cancer Registry Zurich, which exists since 1980, provides the opportunity to address to what extent the number of autopsies in cancer patients has changed over a longer period of time and how often autopsies provide a diagnosis of clinically undetected cancer. Data from the Cancer Registry Zurich consisting of 102,434 cancer cases among 89,933 deceased patients between 1980 and 2010 were analyzed by means of descriptive statistics. The autopsy rate declined from 60 % in 1980 to 7 % in 2010. The total number of autopsies performed decreased from 1179 in 1986 to 220 in 2010. Furthermore, there was also a decline in the rate of newly detected tumours based on autopsy information. In 1980, the rate of newly detected tumours through autopsy was 42 % compared with 2010, when the rate had declined to 17 %. A consequence of the reduced autopsy rate is the reduction of incidental findings at autopsy in cancer registration. However, this reduction has not negatively affected the total incidence of cancer. It seems that the state-of-the-art diagnostic tools used for tumour detection are sufficiently reliable, allowing the scientific community to trust the quality of data provided by cancer registries in spite of decreasing autopsy rates.

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents the results of measurements made on the energy-pile system of the Midfield Dock at Zurich airport. The measurements began in October 2004 and lasted for a period of two years. The system's heat balance, and, in particular, the annual heating and cooling demands are reported as being close to the design values. The report presents a description of the energy-pile and heat pump installations and discusses their performance. The results of measurements made are presented in graphical form. Ground-temperature profiles are looked at and the results of a simulation of thermal performance are discussed. The economical performance of the system is reported as being excellent. The cost of the thermal energy delivered (heating and cooling) is quoted at 0.06 CHF/kWh as compared with 0.08 CHF/kWh for a conventional solution. This means that the additional investment in the energy-pile system is paid back in about 8 years.

    Within the technical oil-production the lipids are released by compression and extraction with hexan. Characteristical for rapeseed is the enormous hexan-retention in meal and the delayed release of hexan in the surrounding area. Cause: the lipids, which are locked in the very compact hulls. - The environmental protection integrated in the process of production requires a reduction/avoidance of hexan-emission. The solution: partial detachment of the hulls as an head-end-operation. A process to dehull rapeseed is known since 1979. In the opinion of oil millers dehulled rapeseed is not continuously pressable due to the lack of stability of compressed solid. The aim of the project is to furnish proof of the possibility to press rapeseed. Therefore two experimental ways are necessary: To find out the characteristics of the material under an axial compression and the variation of material- end compression-parameter, research of the screw-press process with a constant stream of compressed material and an ejection of a stable expeller with a variation of the geometric-, process- and material-parameter. Results: (A) dehulled rapeseed (hulls reduced to 1/4) can be pressed in a screw-press (40 kg/h) continuously; after upscaling the press to a semitechnical press an emission-reduced rapeseed-technology is possible. (B) When rapeseed is pressed, friction and therefore a heat-up is clearly reduced; the oil leaves the press with 40 C; a gentle production of oil is possible; user: Teutoburger Oelmuehle, Ibbenbueren.

    In this work, we share our experiences made at the world-wide first CYBATHLON, an event organized by the Eidgenössische Technische Hochschule Zürich (ETH Zürich), which took place in Zurich in October 2016. It is a championship for severely motor impaired people using assistive prototype devices to compete against each other. Our team, the Graz BCI Racing Team MIRAGE91 from Graz University of Technology, participated in the discipline "Brain-Computer Interface Race". A brain-computer interface (BCI) is a device facilitating control of applications via the user's thoughts. Prominent applications include assistive technology such as wheelchairs, neuroprostheses or communication devices. In the CYBATHLON BCI Race, pilots compete in a BCI-controlled computer game. We report on setting up our team, the BCI customization to our pilot including long term training and the final BCI system. Furthermore, we describe CYBATHLON participation and analyze our CYBATHLON result. We found that our pilot was compliant over the whole time and that we could significantly reduce the average runtime between start and finish from initially 178 s to 143 s. After the release of the final championship specifications with shorter track length, the average runtime converged to 120 s. We successfully participated in the qualification race at CYBATHLON 2016, but performed notably worse than during training, with a runtime of 196 s. We speculate that shifts in the features, due to the nonstationarities in the electroencephalogram (EEG), but also arousal are possible reasons for the unexpected result. Potential counteracting measures are discussed. The CYBATHLON 2016 was a great opportunity for our student team. We consolidated our theoretical knowledge and turned it into practice, allowing our pilot to play a computer game. However, further research is required to make BCI technology invariant to non-task related changes of the EEG.

    Full Text Available Abstract Background As other countries, Switzerland experiences a high or even rising incidence of HIV and sexually transmitted infections (STI among men who have sex with men (MSM. An outpatient clinic for gay men ("Checkpoint" was opened in 2006 in Zurich (Switzerland in order to provide sexual health services. The clinic provides counselling, testing, medical treatment and follow-up at one location under an "open-door-policy" and with a high level of personal continuity. We describe first experiences with the new service and report the characteristics of the population that utilized it. Methods During the 6-month evaluation period, individuals who requested counselling, testing or treatment were asked to participate in a survey at their first visit prior to the consultation. The instrument includes questions regarding personal data, reasons for presenting, sexual behaviour, and risk situations. Number and results of HIV/STI tests and treatments for STI were also recorded. Results During the evaluation period, 632 consultations were conducted and 247 patients were seen by the physician. 406 HIV tests were performed (3.4% positive. 402 men completed the entry survey (64% of all consultations. The majority of respondents had 4 and more partners during the last 12 months and engaged in either receptive, insertive or both forms of anal intercourse. More than half of the responders used drugs or alcohol to get to know other men or in conjunction with sexual activity (42% infrequently, 10% frequently and 0.5% used drugs always. The main reasons for requesting testing were a prior risk situation (46.3%, followed by routine screening without a prior risk situation (24.1% and clarification of HIV/STI status due to a new relationship (29.6%. A fifth of men that consulted the service had no history of prior tests for HIV or other STIs. Conclusion Since its first months of activity, the service achieved high levels of recognition, acceptance and demand in

    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.

Die statistisch verrechneten Einzeldaten wurden zu Streckenprofilen und Zeitreihen verarbeitet, mit dem Ziel, lokale oder regionale Immissionen, Hinweise zu ihrer Entstehung und gegenwaertigen Bedeutung kenntlich zu machen. Hintergrund dieser Bestrebungen ist, dass Fachpublikationen ueber technische Synthesen oder Zwangsanfall der Verbindungen nach Art, Menge und Zeitraum nicht vorliegen, was als Defizit zu betrachten ist. Besonders Tetrachlorbenzen (hauptsaechlich das 1,2,4,5-TeCBz) und das HCBD konnten als Indikatorsubstanzen fuer historische und rezente technische Synthesen chlororganischer Verbindungen sichtbar gemacht werden.

    Full Text Available This paper analyzes the Swedish system of higher education and research with respect to the allocation of research resources. The main findings are a considerable expansion of the system since the post war era as well as a strong trend towards decentralization during the last decades. The earlier visible hand of close governance has left power to an invisible hand of market governance. Also, methods of New Public Management have been introduced. Despite an increasing tendency for research evaluations in Sweden the link to funding has so far been weak, however. Even if resources for research to an increasing extent are allocated through short-term project grants rather than long-term block grants a clear tendency towards funding of fewer and larger programmes rather than many small projects can be observed.

    Within the technical oil-production the lipids are released by compression and extraction with hexan. Characteristical for rapeseed is the enormous hexan-retention in meal and the delayed release of hexan in the surrounding area. Cause: the lipids, which are locked in the very compact hulls. - The environmental protection integrated in the process of production requires a reduction/avoidance of hexan-emission. The solution: partial detachment of the hulls as an head-end-operation. A process to dehull rapeseed is known since 1979. In the opinion of oil millers dehulled rapeseed is not continuously pressable due to the lack of stability of compressed solid. The aim of the project is to furnish proof of the possibility to press rapeseed. Therefore two experimental ways are necessary: (1) To find out the characteristics of the material under an axial compression and the variation of material- and compression-parameter, (2) research of the screw-press process with a constant stream of compressed material and an ejection of a stable expeller with a variation of the geometric-, process- and material-parameter. Results: (A) dehulled rapeseed (hulls reduced to 1/4) can be pressed in a screw-press (40 kg/h) continuously; after upscaling the press to a semitechnical press an emission-reduced rapeseed-technology is possible. (B) When rapeseed is pressed, friction and therefore a heat-up is clearly reduced; the oil leaves the press with 40 C; a gentle production of oil is possible; user: Teutoburger Oelmuehle, Ibbenbueren. (orig.) [German] Bei technischer Oelgewinnung werden die Lipide durch Pressen und Extrahieren mit Hexan freigesetzt. Spezielles Merkmal von Raps ist die starke Hexanretention im Schrot und verzoegerte Hexanfreisetzung in die Umgebung. Verursacher: die in den kompakten Huellen eingeschlossenen Lipide. - Produktionsintegrierter Umweltschutz erfordert Minderung / Vermeidung der Hexanemissionen. Der Weg: partielles Abtrennen der Huellen als Head

    Full Text Available Unfavorable job market conditions and the related increase in pressure to legitimate the social sciences and humanities have drawn attention within these disciplines to approaches which have turned their own academic considerations into a starting point for practical concepts. In this sense, the following approach out of the field of applied discourse analysis attempts to develop application-oriented suggestions based on the analysis of authentic oral examinations at the university level. Beginning with an analysis of observable communicative behavior on behalf of oral examination participants, the following didactic suggestions aim to develop solid advice for instructors and students. Both the analysis and the practical suggestions aim to establish the scopes and limits concerning communication in institutionally organized exam situations. The aim of this approach is to support examination participants in recognizing and utilizing the given range of communicative possibilities.

    The aim of these investigations is to create a first basic data set for geothermal mapping in Kanton Zurich and adjacent regions. These data include undisturbed ground temperatures, thermal conductivities and porosities of rocks as well as heat flow determinations. The temperature profiles in the ground have been logged, to depths up to 300 m in several borehole heat exchangers, in the Canton Zurich and adjacent regions. A new, patented wireless instrument developed by the authors (NIMO-T / Non-wired Immersible Measuring Object for Temperature) was used to perform the measurements. Such measurements are possible in backfilled boreholes with installed double U-tube heat exchangers, not yet connected to the heat pump, filled with water standing since at least 7 days. A total of 33 boreholes have been measured; 24 of them enabled heat flow determinations. The NIMO-T probe (weight 100 g, length 20 cm, diameter 2 cm; with a built-in miniature data logger) sinks though its own weight with about 7 m per minute in one of the water-filled U-tube limbs and records every 25 cm a temperature and pressure (=measuring depth) value. Relative temperature accuracy is {+-} 0.0015 {sup o}K, for depth {+-} 20 cm. After the probe has reached the U-tube bottom it can be easily flushed back to the surface by pumping, where data readout to a laptop computer follows. For terrestrial heat flow determinations the rock thermal conductivities (of the undisturbed, water-saturated, compact rocks at in-situ pressure) would be needed. Laboratory measurements on rock samples (cores, cuttings) can only approximate these conditions. The thermal conductivities and related porosities of cuttings have been compared and calibrated by measurements on cores. The ground temperatures are influenced in the uppermost 20 meters by seasonal surface temperature variations, between 20 and about 100 m depth by climatic warming in the past 200-300 years. Below 100 m the temperature increase with depth is more or

  17. Josef Frank and the history of architecture: Gothic and the Renaissance, Leon Battista Alberti and Albrecht Dürer in the architectural discourse on Neues Bauen at the beginning of the 1930s

    Directory of Open Access Journals (Sweden)

    Caterina Cardemone

    2016-06-01

    Full Text Available The paper focuses on Josef Frank’s convinced use of historiographical arguments in his sharp critique of German modernist architecture. Frank’s attention to architectural history dates back to his education at the Technische Hochschule in Vienna, with Carl König, and the writing of a doctoral thesis on Leon Battista Alberti’s religious buildings in 1910. If a profound knowledge of Alberti’s writings informs Frank’s entire theoretical work, the point discussed here is the parallel between Neues Bauen and Gothic traced by Frank to exclude Neues Bauen from a true modernity, based, on the opposite, on a classical tradition of thought. An attempt is made to reconstruct Frank’s historiographical references and to insert his work in the broader historiographical context, thus highlighting a close link between architectural theory and critique on the one hand and contemporary historiographical constructions on the other.

    Urban mining is increasingly being recognised as an important component of resource strategies of public authorities, not only because it contributes to environmental protection, but also because it is a source of valuable recyclable materials. We demonstrate that the sustainable livelihoods (SL) framework can be used for public policy making in waste management by presenting the approach and experiences of a review study termed 'urban mining potential analysis' and its application to antimony, copper, gypsum, gold and rare earth elements. This article uses the rare earth element (REE) group to illustrate and present an overview over information and knowledge gaps concerning urban mining. The analysis shows that rare earth element recycling can be more environmentally friendly than primary production, particularly if the latter comes from countries with weak enforcement of environmental legislation. On the other hand REE recycling often cannot compete with large scale primary production because market prices do not reflect the social and environmental impacts of production, and because the avoided impacts of waste decontamination and reduced waste production are not considered. The urban mining potential analysis can be used to support decision making and the setting of priorities for future research and public action. The findings of the study and expert opinions based thereon contribute to the selection of measures and the formulation of public waste management and resource strategies in general.

    A number of radiogrammetrical metacarpal indices are in use, some of which have been adapted for children. The purpose of this study was to compare four known indices - bone mineral density (BMD), relative cortical area, Exton-Smith index, bending breaking resistance index - and the more recently defined pediatric bone index (PBI) according to the two criteria of minimum height dependence and minimum variability in children of equal bone age. A total of 3,121 left-hand radiographs from 231 healthy Caucasian children ranging in age from 3 to 19 years old were analysed using BoneXpert registered , a programme for automatic analysis of hand radiographs and assessment of bone age. Dependence on height for chronological age or bone age and the mean relative standard deviation were lowest in the PBI for both genders pooled. The differences in height dependence were statistically significant and are shown to be clinically relevant. Reference data for PBI are presented. PBI may be a better indicator than BMD for bone health in children; however, verification in a clinical group is needed. (orig.)

    Aerosols and ultrafine particles are of significance for environmental protection, e.g. in connection with protecting humans against injuries to their health or the protection of products. Due to their low mass, the mass concentration of particles of less than 1 {mu}m is generally low, even if their concentration in numbers is high. These particles are increasingly attaining significance as carriers, e.g. of pollutants which still trigger undesirable reactions in trace concentrations or even as single molecules. (orig.) [German] Aerosole und ultrafeine Partikel haben ihre Bedeutung in Bezug auf den Umweltschutz z.B. beim - Schutz des Menschen vor gesundheitlichen Schaeden und - den Schutz von Produkten.

Zunehmend wichtig wird die Rolle dieser Partikel als Carrier fuer z.B. Schadstoffe, die schon im Bereich von Spurenkonzentrationen oder sogar molekular unerwuenschte Wirkungen ausloesen. (orig.)

    On the basis of a political agreement, the subsidized German hard coal mining will be socially acceptable terminated by end of 2018. In 2012, this decision will be reassessed. Even after the abandonment of all mining activities subsequent burdens are inevitable. In this article, the long-term effects resulting from a mining industry history, which is spanning over more than 200 years, and their possible consequences are pointed out in particular in connection with the economically long-term meaningful cessation of mine dewatering measures. Furthermore, a frame of action within possibly concerned ranges is developed for this case. (orig.)

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

    Science.gov (United States)

    Schöb, Reto; Loree, Howard M.

    Herzkrankheiten verursachen allein in den Vereinigten Staaten jährlich mehr als 700’000 Todesfälle. Ungefähr 3 Millionen Patienten in den U.S.A. leiden gemäss der American Heart Association (AHA) und dem National Heart, Lung and Blood Institute (NHLBI) an kongestivem Herzversagen (Congestive Heart Failure, CHF), welches eine chronische, sehr entkräftende und degenerative Krankheit ist: Das Herz ist dabei unfähig, hinreichend Blut zu den Organen des Körpers zu pumpen. Über 400’000 Fälle von CHF werden jedes Jahr diagnostiziert. Ähnliche Zahlen werden für Europa und Japan zusammen geschätzt. Basierend auf Daten vom AHA und NHLBI beträgt die fünfjährige Überlebensrate für CHF-Patienten lediglich etwa 50% [1]. 70’000-120’000 dieser Patienten könnten von einer Herzverpflanzung profitieren. 1999 wurden in den USA aber nur 2185 Herztransplantationen durchgeführt während die Warteliste über 4000 Patienten beträgt [2]. Ein akuter Mangel an Spenderherzen und die enormen Kosten (250’000-400’000 USD pro Patient) sind die begrenzenden Faktoren für Herztransplantationen [3]. Dies bedeutet, dass eine riesige Anzahl von Patienten durch ein zuverlässiges und verschleissfreies, nichtthrombotisches, total implantierbares, künstliches Herz gerettet werden könnten. Bis heute jedoch kein derartiges Implantat kommerziell verfügbar.

    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.

Das eingeleitete saubere Wasser erwaermt sich an der aeusseren Rohrwandung auf dem Weg nach unten und wird dann im inneren waermeisolierten Steigrohr an die Oberflaeche befoerdert. Das erwaermte Waser wird in Prenzlau ueber eine Waermepumpe zu Fernwaermezwecken benutzt. Am 26.3.1994 begannen die Bohrarbeiten, und am 10.11.1994 ging die gesamte Anlage in Betrieb, die heute ca. 1100 Wohnungen mit Waerme und Warmwasser versorgt. Die Erdwaermetiefensonde Prenzlau mit einer Tiefe von 2800 m deckte in den ersten beiden Betriebsjahren ueber 20 % des Waermebedarfs des Fernwaermenetzes Prenzlau-West. Die Jahresdauerleistung der Erdwaermetiefensonde mit 500 kW liegt bei 8-12 % der witterungsbedingten Jahreshoechstlast. Die Sonde gestattet Spitzenleistungen im Stundenbereich von mehr als 700 kW.

    Subject of the interdisciplinary work are the following priorities: Discussion and results of the economic opportunities and risks as well as sociotechnological relationships in the use of a campus management system (CMS) under strong college complex organizational structures. Various stages in the life cycle of a software solution are affected. The main focus lies in the context of the underlying themes on the selection, integration and migration of CMS. In particular, the research results of a complex process model for the creation of an economic analysis to integrate CMS solutions form the major focus. Investigation of the status quo of external funding and its IT-based management at German universities. Characterization of the actual situation, development of science-based target concepts and derivation of possible implications and relevant recommendations for action for the organizational and process-oriented (re)design of IT support. Green Business (GB) as a global enterprise framework to increase sustainability in supply chains for the purposes of corporate governance. IT serves as an operative trigger to the strategic sustainability goals of companies. Fluctuations caused by renewable energy (RE), endanger the stability in the European energy network and lead to inefficient compensation and balancing power. In-depth investigations show two main approaches to increase network stability: producer-sided load management through active management of virtual power plants (VPP) based on neuro simulated forecasting methods under various use of real-time information (such as weather data) and prize-controlled, semiautomated use of energy on the demand-side. All these research activities have this in common: they underscore the relevance of information systems for effective organization- and workflow-design and the development of potentials as well as fundamental benefit effects. For the organizational- and project-success, however, the choice of investment volume, the design of appropriate systems and process orientation is an essential guarantee. All the investigated sub-areas of this work take that same approach into account by investigating concrete scenarios. In addition, attention is drawn to a mismatch between the status quo of research and practice. The identified open problems lead to answers of research questions which address scientific rigor and relevance. The work operates in all topics with methodologically found, qualitatively and empirically validated results. In addition, relevant national, especially international literature sources make a central foundation.

  9. [The duty of official discretion for members of the animal experiment commission (notably in the Canton Zurich)].

    Science.gov (United States)

    2007-01-01

    The legal prohibition to disclose an official secret as laid down in Article 320 of the Swiss criminal code (StGB) also applies for members of the Committee on Animal Experimentation. This implies an extensive obligation to keep absolute secrecy of the knowledge they obtain within their position. However, due to the applicable law - and mainly in view of the principle of public trial constitutionally guaranteed in many Swiss regions - a number of specifications have to be addressed and exceptions to the prohibition are conceivable. Nevertheless, it cannot be denied that overstretching the notion and definition of a secret laid down in Article 320 StGB is incompatible with the constitutional obligation of the members of the Committee on Animal Experimentation to fulfil legal animal welfare regulations. This is the reason why there should be a general and fundamental liberalisation of the official discretion; and the Confederate Animal Protection Law would be the right place to implement such a change. Even though such legal provisions are currently not foreseen, various constellations already exist in practice, in which members of the Committees are released from their duty of official discretion, so that an exchange of ideas - also regarding legal aspects - with third parties and institutions is possible.

    Over the past few years assessments on the economics of maglev railway systems have been published at more or less regular intervals. In many cases, the authors of such studies rely on outdated secondary literature, with the result that they lack an awareness of the current technical state of the art on which to base an objective comparison. They frequently also base their arguments and calculations on simplified methods, plausibility assessments, and estimates. Use is also made of new variables that are rather foreign to the transport science literature with the aim of demonstrating that the figures published on maglev systems by the industry are way too optimistic. But it is not sufficient to draw on a sound knowledge of wheel/rail technology as a basis for making a judgement on maglev technology. The article discusses the major information inputs into a system comparison. (orig.)

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

    2010-01-01

    We present a small single camera imaging system that provides a continuous 280 0 field of view (FOV) inspired by the large FOV of insect eyes. This is achieved by combining a curved reflective surface that is machined into acrylic glass with lenses covering the frontal field that otherwise would have been obstructed by the mirror. Based on the work of Seidl (1982 PhD Thesis Technische Hochschule Darmstadt), we describe an extension of the 'bee eye optics simulation' (BEOS) model by Giger (1996 PhD Thesis Australian National University) to the full FOV which enables us to remap camera images according to the spatial resolution of honeybee eyes. This model is also useful for simulating the visual input of a bee-like agent in a virtual environment. The imaging system in combination with our bee eye model can serve as a tool for assessing the visual world from a bee's perspective which is particularly helpful for experimental setups. It is also well suited for mobile robots, in particular on flying vehicles that need light-weight sensors.

  7. The Second Mössbauer Effect

    Science.gov (United States)

    Kienle, Paul

    "The Second Mössbauer Effect" was the headline of the "Spiegel" (a German weekly journal like the "Times") from May 13, 1964 for announcing the foundation of the "Physik-Department" at the Technische Hochschule München (THM), as it was still called at this time. Maier-Leibnitz was irritated by this headline because the article did not mention at all his contribution to the consolidation of the structure of the three physics institutes (Experimental, Technical, and Theoretical Physics) in the beginning of the sixties. Already in the late fifties ML's Institute for Technical Physics was overloaded with students working on their diploma or doctoral theses, because research in the new field of applied nuclear physics was very attractive and ML had for each student who applied an interesting research project. In the average, ML had to supervise between 150-200 diploma students, an impossible task. So, young postdoctoral students had to help him out by taking over the duties of professors. In a letter to the Bavarian Ministry of Education and Arts in 1957 he complained: "The directors of the institutes are hopelessly surcharged and the institutes are overcrowded, the resources for research projects are totally insufficient and lots of time and energy is wasted for finding additional resources."

    In this interview, John Wasson (Fig. 1) describes his childhood and undergraduate years in Arkansas and his desire to pursue nuclear chemistry as a graduate student at MIT. Upon graduation, John spent time in Munich (Technische Hochschule), the Air Force Labs in Cambridge, MA, and a sabbatical at the University of Bern where he developed his interests in meteorites. Upon obtaining his faculty position at UCLA, John established a neutron activation laboratory and began a long series of projects on the bulk compositions of iron meteorites and chondrites. He developed the chemical classification scheme for iron meteorites, gathered a huge set of iron meteorite compositional data with resultant insights into their formation, and documented the refractory and moderately volatile element trends that characterize the chondrites and chondrules. He also spent several years studying field relations and compositions of layered tektites from Southeast Asia, proposing an origin by radiant heating from a mega-Tunguska explosion. Recently, John has explored oxygen isotope patterns in meteorites and their constituents believing the oxygen isotope results to be some of the most important discoveries in cosmochemistry. John also describes the role of postdoctoral colleagues and their important work, his efforts in the reorganization and modernization of the Meteoritical Society, his contributions in reshaping the journal Meteoritics, and how, with UCLA colleagues, he organized two meetings of the society. John Wasson earned the Leonard Medal of the Meteoritical Society in 1992 and the J. Lawrence Smith Medal of the National Academy in 2003.

    One of the intraoperative challenges of fetal spina bifida repair is skin closure when there is an extended skin defect. Thus, we examined whether distally pedicled random pattern transposition flaps (TFs) are a valid option to overcome this problem. All patients undergoing in utero repair of spina bifida with application of a TF for back skin closure were analyzed focusing on intraoperative flap characteristics and postoperative flap performance. In 30 (70%) of the 43 fetuses a primary skin closure was achieved, in 5 (12%) a skin substitute was used, and in 8 (18%) a TF was applied. Flap raising and insertion was uneventful and perfusion was sufficient in all 8 fetuses (100%). In 3 fetuses (37%) the donor sites were closed primarily, and in 5 (63%) a skin substitute was used for coverage. At birth, 7 flaps were viable and provided robust skin coverage over the center of the former lesion. Complications included a small skin defect with CSF leakage in 1 patient (13%). During open fetal spina bifida repair, TFs can be safely and efficaciously used to obtain solid and durable skin coverage over lesions too large to allow conventional primary skin closure. © 2017 S.

    2016-01-01

    This present workshop, the 5. Computational Fluid Dynamics for Nuclear-Reactor Safety (CFD4NRS-5), in the biennial series of such Nuclear Energy Agency (NEA) and International Atomic Energy Agency (IAEA) sponsored events, a tradition which began in Garching in 2006, follows the format and objectives of its predecessors in creating a forum whereby numerical analysts and experimentalists can exchange information in the application of computational fluid dynamics (CFD) to nuclear power plant (NPP) safety and future design issues. The emphasis, as always, was, in a congenial atmosphere, to offer exposure to state-of-the-art (single-phase and multi-phase) CFD applications reflecting topical issues arising in NPP design and safety, but in particular to promote the release of high-resolution experimental data to continue the CFD validation process in this application area. The reason for the increased use of multi-dimensional CFD methods is that a number of important thermal-hydraulic phenomena occurring in NPPs cannot be adequately predicted using traditional one-dimensional system hydraulics codes with the required accuracy and spatial resolution when strong three-dimensional motions prevail. Established CFD codes already contain empirical models for simulating turbulence, heat transfer, multi-phase interaction and chemical reactions. Nonetheless, such models must be validated against test data before they can be used with confidence. The necessary validation procedure is performed by comparing model predictions against trustworthy experimental data. However, reliable model assessment requires CFD simulations to be undertaken with full control over numerical errors and input uncertainties. The writing groups originally set up by the NEA have been consistently promoting the use of best practice guidelines (BPGs) in the application of CFD for just this purpose, and BPGs remain a central pillar of the simulation material accepted at this current workshop, as it was at its predecessors. In order to assess the maturity of CFD codes for use in reactor safety and design, it is necessary to establish a database of CFD-grade experimental material; this remains the second pillar of the CFD4NRS series of workshops. The third pillar is the advancing use of CFD modelling in multi-phase applications, these days known commonly as CMFD. Here, the challenges are considerable. Not only are the governing equations an order of magnitude more complex than for single-phase applications, but a validation database for which there is genuine three-dimensional involvement remains quite sparse. Of course, multi-phase CFD is not the sole province of NPP applications, and important developments are taking place in other industrial arenas, such as in the chemical and processing industries, and in environmental studies

  15. Exergetic analysis of the heat pump installed in the Limmat school building in Zurich; Exergieanalyse der Waermepumpe im Schulhaus Limmat - Schlussbericht

    In large buildings, heat pumps todays are only used in a small number of cases. In those rare cases, they are operated with synthetic working fluids and are mainly used for low temperature heating. Since January 2006, a heat pump with Propane as working fluid has been operating in a school building in Zuerich (Schulhaus Limmat), which provides space heating and hot water for the old building erected in 1909. As a heat source, a main channel of sewage is used, an ideal heat source, which is only rarely used nowadays. Hence, the installation has a pioneering role in many aspects and has been analysed in detail during the current project. During this project, the Propane heat pump in the Schulhaus Limmat as well as the hydraulic system have been analysed in respect to its exergetic losses. The heat pump has a seasonal performance factor of 2.7. The investigation has shown that the heat pump does not operate in an optimal way and that the hydraulic has room for improvement with respect to exergetic losses. In implementing the measures suggested in this report, the seasonal performance factor can be increased to about 4.4. (author)

    This study focuses on the investigation and quantification of low-cost sensor performance in application fields such as the extension of traditional air quality monitoring networks or the replacement of diffusion tubes. For this, sensor units consisting of two boxes featuring NO2 and O3 low-cost sensors and wireless data transfer were engineered. The sensor units were initially operated at air quality monitoring sites for 3 months for performance analysis and initial calibration. Afterwards, they were relocated and operated within a sensor network consisting of six locations for more than 1 year. Our analyses show that the employed O3 and NO2 sensors can be accurate to 2-5 and 5-7 ppb, respectively, during the first 3 months of operation. This accuracy, however, could not be maintained during their operation within the sensor network related to changes in sensor behaviour. For most of the O3 sensors a decrease in sensitivity was encountered over time, clearly impacting the data quality. The NO2 low-cost sensors in our configuration exhibited better performance but did not reach the accuracy level of NO2 diffusion tubes (˜ 2 ppb for uncorrected 14-day average concentrations). Tests in the laboratory revealed that changes in relative humidity can impact the signal of the employed NO2 sensors similarly to changes in ambient NO2 concentration. All the employed low-cost sensors need to be individually calibrated. Best performance of NO2 sensors is achieved when the calibration models also include time-dependent parameters accounting for changes in sensor response over time. Accordingly, an effective procedure for continuous data control and correction is essential for obtaining meaningful data. It is demonstrated that linking the measurements from low-cost sensors to the high-quality measurements from routine air quality monitoring stations is an effective procedure for both tasks provided that time periods can be identified when pollutant concentrations can be accurately predicted at sensor locations.

    This final report for the Swiss Federal Office of Energy (SFOE) presents a technical handbook on the principles and planning processes involved in designing and installing heating systems for low-energy and so-called passive houses with air-renewal systems and provides examples taken from practice. The manual is intended to provide guidance to architects, planners and manufacturers. In the first part of the three-part manual, the basics of energy balances, ecological assessment and modern control techniques are dealt with, the second part covers integral planning, feasibility and manufacturing techniques and the third part gives examples of three houses built to so-called 'Minergie' low-energy and 'passive house' standards. The factors to be taken into account when planning low-energy and passive houses heated with heat pumps are discussed and calculation tools aiding the dimensioning and simulation of the systems are introduced.

    2003-07-01

    This comprehensive article presents directives, regulations and technical guidelines in force in Germany in what regards protection against legionnaires illness. These documents formulate the requirements applicable to domestic hot water installations, bathing pools and ventilation/air conditioning systems, and clarify liability issues. They have been worked out after casualties have been recorded and a European directive on water quality for human usage issued. Whereas the water utility is responsible for water quality up to the main water inlet into the building, the building owner is responsible for in-house water installations. Regulations do not apply to small systems and single-family houses. Planners and installers have to follow recommendations and prescriptions, and regional authorities have to check the regulations' enforcement. Periodic water quality checks are mandatory. Education and training of operation and maintenance staff is prescribed. The documents include the procedures to be followed in the case of the detection of a high legionella concentration in a part of the checked installation: immediate measures, modification of the installation, re-checks of water quality. It is emphasized that the bacteria are always present in water installations and that only their proliferation shall be prevented, especially by avoiding standing hot water in distribution pipework, through appropriate design, installation and water flow balancing, as well as by avoiding critical water temperatures favourable to legionella proliferation.

    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.)

    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.)

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

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

    Taking the hydrocarbon exploration project in Zimbabwe as an example, it is shown how technical cooperation (TC) projects and commercial exploration (Mobil Oil in the Zambezi Valley) can be initiated as a result of the interaction of the BGR's own research, cooperation with the Geological Survey of Zimbabwe and know-how transfer. The early activities comprised acquisition and interpretation of radiometric and aeromagnetic surveys (German industry/BGR/BMFT (research)/TC project) and sedimentological investigations (BGR TC project). A regional hydrocarbon prospectivity study and a magnetotelluric survey followed (both BGR TC projects). These activities initiated the commercial hydrocarbon exploration which is accompanied by a BGR TC project (technical third party opinion, government consultancy) including investigations of potential source rocks in other Karoo basins.

    Training and awareness at all levels are central elements in the development of markets and technologies. One reason why rural electrification projects often fail is the fact that training has been neglected (International Energy Agency IEA, 2003). All boundary conditions must be considered, i.e. cultural, social, economic, organisational and financial (Will and Vogt, 2003). This necessitates a wide range of competences for projecting, implementation, commissioning and marketing of solar systems. The training requirements must be analyzed and put into practice by specific, user-oriented training measures. This contribution outlines the spectrum of relevant training contents in the field of photovoltaic energy conversion and presents practical examples of how customer-specific training programmes can be developed. (orig.) [German] Ausbildung, Training und Bewusstseinsbildung auf allen Ebenen gelten zurecht als zentrale Aufgabe fuer die Entwicklung von Maerkten und Technologien. Ein Grund fuer das Scheitern vieler Projekte und Programme zur laendlichen Elektrifizierung liegt in der unzureichenden bzw. nicht bedarfsgerechten oder nicht vorhandenen Schulung von am Projekt beteiligten Personen auf allen Ebenen (International Energy Agency IEA, 2003). Wie diese unbefriedigenden Erfahrungen zeigen, muessen bei der Planung von PV-Solarstromanlagen die verschiedensten Randbedingungen mit einbezogen werden. Sowohl bei netzgekoppelten wie auch netzfernen Maerkten sind neben den technischen kulturelle, soziale, oekonomische, organisatorische und finanzielle Aspekte zu beruecksichtigen (Will und Vogt, 2003). Das bedeutet, dass fuer die Planung, Implementierung, Inbetriebnahme und breite Vermarktung von Solarsystemen vielfaeltige Kompetenzen erforderlich sind, welche durch Bedarfsanalysen erfasst und durch spezifische und zielgruppenorientierte Trainingsmassnahmen kontinuierlich aufgebaut werden muessen. Wesentliches Ziel dieses Beitrages ist es, das Spektrum der relevanten Trainingsinhalte im Bereich Photovoltaik darzustellen und den Nutzen kundenspezifischer Ausbildungsprogramme anhand praktischer Beispiele und Erfahrungen exemplarisch zu beleuchten.

    Inflow boundary conditions for turbulent plane channel flow are generated by solving evolution equations only for the most energetic eddies. The dynamical systems are derived by Galerkin projecting the Navier-Stokes equations onto the subspaces spanned by various sets of the most energetic modes from a proper orthogonal decomposition (POD) of the same flow. Low-energy small-scale POD-modes are added randomly in order to impose some energy in the high wave number range. This is found to be crucial in order to more rapidly establish the correct level of dissipation and achieve a more realistic distribution of energy between the velocity components. The method is tested on a DNS of R*=180 and a LES of R*=400. Statistics such as mean velocity, rms-profiles, turbulent shear-stress and energy spectra become close to the fully developed state within 1500 wall units downstream the inlet.

    This report for the Swiss Federal Office of Energy (SFOE) describes the borehole that has been driven into the underlying crystalline rock of the Rhine valley near Basle. This work has been carried out within the framework of the 'Deep Heat Mining' project. The 2,755 metre deep borehole provides geological information essential for the realisation of a proposed geothermal power station using the 'Hot Dry Rock' process. The boring of the test borehole is described. The results obtained from samples taken from the test borehole and the measurements made in it are presented, including details on geological formations, temperature, gas measurements and rock strain values. The author is of the opinion that the chances of finding temperatures of at least 200 {sup o}C in a depth of 5 km - as foreseen in the 'Deep Heat Mining' project - can be considered as being quite high.

    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.)

    The design of components of metallic high-temperature materials by the finite element method requires the application of phenomenological viscoplastic material models. The route from the choice of a convenient model, the numerical integration of the equations and the parameter identification to the design of components is described. The Chaboche-model is used whose evolution equations are explicitly integrated. The parameters are determined by graphical and numerical methods in order to use the material model for describing the deformation behaviour of an intermetallic titanium aluminide alloy. (orig.)

    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.)

    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.

    A catalog of ergonomic recommendations for organizational measures and design of paper documented work aids for accident management situations in nuclear power plants was developed. Attention was given to provide recommendations meeting practical needs and being sufficiently flexible to allow plant specific adaptation. A weight was assigned to each recommendation indicating its importance. The development of the recommendations was based on the state of the art concerning research and practical experience. Results from walk-/talk-through experiments, training and exercises, discussions with on-site experts, and investigations of emergency manuals from German and foreign nuclear power plants were taken into account. The catalog is founded on a broad knowledge base covering important aspects. The catalog is intended for qualitative evaluation and design of organizational measures and procedures. The catalog shall assure high quality. The project further provides an important contribution to the standardization of organizational and human centered demands concerning accident management procedures. Thus it can contribute to develop general regulations regarding ergonomic design of accident management measures. (orig.) [Deutsch] Im Rahmen des Vorhabens wurde ein Katalog von ergonomischen Empfehlungen zu organisatorischen Vorkehrungen und zur Gestaltung schriftlicher Arbeitsmittel fuer Notfallsituationen in Kernkaftwerken entwickelt. Dabei wurde besonderer Wert darauf gelegt, dass die Empfehlungen praxisgerecht sind und ausreichend Spielraum zur Realisierung anlagenspezifischer Vorstellungen bieten. Die Empfehlungen sind hinsichtlich ihrer Bedeutung mit unterschiedlichen Gewichten versehen. Fuer die Entwicklung der Empfehlungen des Katalogs wurden sowohl der Stand von Forschung und Anwendung als auch praktische Erfahrungen ausgewertet. Hierbei wurden Erkenntnisse aus Anlagenbegehungen, Notfalluebungen, Diskussionen mit Fachpersonal aus Anlagen und realisierten Notfallhandbuechern in- und auslaendischer Anlagen beruecksichtigt. Dem Katalog liegt somit eine breite, wesentliche Aspekte abdeckende Basis unterschiedlicher Informationsquellen zugrunde. Die Empfehlungen des Katalogs koennen sowohl fuer die Planung und Optimierung als auch fuer die Beurteilung herangezogen werden. Sie sollen zu einem hohen Qualitaetstandard beitragen. Das Vorhaben leistet ferner einen wichtigen Beitrag zur Harmonisierung sowohl organisatorischer als auch auf den Menschen bezogener Anforderungen im Rahmen des Anlageninternen Notfallschutzes. Der Katalog kann somit auch als Grundlage fuer eine noch zu erstellende Rahmenempfehlung zum Aufbau und zur Gestaltung von Notfallmassnahmen herangezogen werden. (orig.)

    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.

    The Forschungszentrum Juelich GmbH (FZJ), together with the Aachen University Rheinisch-Westfaelische Technische Hochschule (RWTH) and the French Alternative Energies and Atomic Energy Commission (CEA Cadarache) are involved in a cooperation aiming at characterizing toxic and reactive elements in radioactive waste packages by means of Prompt Gamma Neutron Activation Analysis (PGNAA). The French and German waste management agencies have indeed defined acceptability limits concerning these elements in view of their projected geological repositories. A first measurement campaign was performed in the new Prompt Gamma Neutron Activation Analysis (PGNAA) facility called MEDINA, at FZJ, to assess the capture gamma-ray signatures of some elements of interest in large samples up to waste drums with a volume of 200 liter. MEDINA is the acronym for Multi Element Detection based on Instrumental Neutron Activation. This paper presents MCNP calculations of the MEDINA facility and quantitative comparison between measurement and simulation. Passive gamma-ray spectra acquired with a high purity germanium detector and calibration sources are used to qualify the numerical model of the crystal. Active PGNAA spectra of a sodium chloride sample measured with MEDINA then allow for qualifying the global numerical model of the measurement cell. Chlorine indeed constitutes a usual reference with reliable capture gamma-ray production data. The goal is to characterize the entire simulation protocol (geometrical model, nuclear data, and postprocessing tools) which will be used for current measurement interpretation, extrapolation of the performances to other types of waste packages or other applications, as well as for the study of future PGNAA facilities.

  1. Seismic Investigation of the Glacier de la Plaine Morte, Switzerland

    2017-04-01

    Glacier de la Plaine Morte is a plateau glacier along the border between Valais and Berne cantons. It covers a narrow elevation range and is extremely vulnerable to climate change. During snow melt, it feeds three marginal lakes that have experienced sudden subglacial drainage in recent years, thereby causing flooding in the Simme Valley below. Of greatest concern is Lac des Faverges at the southeastern end of the glacier that has drained near the end of July in recent years, with flood levels reaching capacity of flood control systems downstream. The lake levels are carefully monitored but precise prediction has not yet been achieved. In the search for precursory ice fracturing to the lake drainage to improve forecast, four seismic arrays comprised of five short-period borehole seismometers provided by Eidgenössische Technische Hochschule (ETH), Zürich as well as fifteen 3-component geophones from the Geophysical Instrument Pool Potsdam (GIPP) collected continuous seismic data for about seven weeks during the summer of 2016. We present initial results on discharge dynamics as well as changing noise levels and seismicity before, during and after the drainage of Lac des Faverges. Compared to previous recent years, the 2016 drainage of Lac des Faverges occurred unusually late on August 28. With an aperture between 100 and 200 m, the small arrays recorded many hundred ice quakes per day. A majority of the events exhibits clearly dispersed, high-frequency Rayleigh waves at about 10 Hz and higher. A wide distribution of events allows us to study azimuthal anisotropy and its relationship with the orientation of glacial crevasses.

    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.)

    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 concept is fantastic: studying independently of time and space. Within this notion of a virtual university, this scenario appears realistic. In particular, the continual advancement of technical possibilities gives credence to this aspiration. The reality of it, however, looks different. In fact, there is a multiplicity of single projects (mostly pilot), but a connection between the technical and the university is hard to find.

    During five and a half years of studying veterinary medicine, students should in addition to theoretical knowledge acquire sufficient practical skills. Considering animal welfare and ethical aspects, opportunities for hands-on learning on living animals are limited because of the high annual number of students. The first German veterinary clinical-skills lab, established in 2013 at the University for Veterinary Medicine Hannover, Foundation (TiHo), offers opportunities for all students to learn, train and repeat clinical skills on simulators and models as frequently as they would like, until they feel sufficiently confident to transfer these skills to living animals. This study describes the establishment of clinical-skills lab training within the students' practical education, using the example of the small-animal clinic of the TiHo. Two groups of students were compared: without skills lab training (control group K) and with skills lab training (intervention group I). At the end of both the training and a subsequent 10-week clinical rotation in different sections of the clinic, an objective structured clinical examination (OSCE) was performed, testing the students' practical skills at 15 stations. An additional multiple-choice test was performed before and after the clinical rotation to evaluate the increased theoretical knowledge. Students of group I achieved significantly (p ≤ 0.05) better results in eight of the 15 tested skills. The multiple-choice test revealed a significant (p ≤ 0.05) gain of theoretical knowledge in both groups without any differences between the groups. Students displayed a high degree of acceptance of the skills lab training. Using simulators and models in veterinary education is an efficient teaching concept, and should be used continually and integrated in the curriculum.

    A detailed literature review has been carried out on the topic to identify the areas requiring further investigations. Based on this investigations have been carried out to evaluate the influence of dissolved nitrogen in weld metals on their toughness and strain aging behaviour through fracture mechanics as well as conventional impact testing approaches. MMA C-Mn steel weld metals bearing nitrogen between 80 to 210 ppm were investigated under four different post-weld conditions, namely: 1. as welded, 2. stress relieved, 3. artificially strain aged and 4. artificially strain aged and stress relieved. Quantitative metallography and low load microhardness studies of microphases were integral part of these investigations. The results demonstrate the highly detrimental effect of nitrogen on the toughness behaviour of C-Mn steel weld metal particularly under strain aging conditions. This is substantiated through decrease of acicular ferrite with the accompanying increase in primary ferrite and ferrite with second phases in the microstructures. Also, there is a distinctive increase in acicular ferrite microhardness. Post-weld stress relieving heat treatment under these conditions effects only marginal improvement in toughness and shifts the fracture behaviour from brittle to ductile or quasi-ductile only in the case of low nitrogen weld metals. Comparing the results of the CTOD and Charpy tests, it is observed that both methods measure the influence of nitrogen on toughness behaviour in the same trend but the magnitudes of the effect measured are different whereby the fracture mechanics method appears very conservative. (orig.) [Deutsch] Untersucht werden der Einfluss von Stickstoff im Bereich von 80-120 ppm auf die Zaehigkeit und Reckalterungsversproedungs-Verhaeltnisse des C-Mn-Strahlschweissgutes. Die Pruefungen erfolgen mit technologischen Kerbschlagbiege- und CTOD-Versuchen an Schweissguetern, die durch mehrlagiges Lichtbogenschweissen hergestellt wurden, unter vier Versuchsbedingungen. Die untersuchten Zustaende der Schweissgueter sind: 1. wie geschweisst (AW), 2. spannungsarmgeglueht (SR) - 580 C, 120 min., 3. reckgealtert (SA) - 10%-pre-Kompressionsdehnung und nachfolgende Alterung bei 250 C, 30 min, und 4. reckgealtert und nachfolgend spannungsarmgeglueht (SAS)-SA+SR. Die Beziehungen zwischen Stickstoffanteilen und Zaehigkeit bzw. Reckalterung sind durch mikrostrukturelle Aenderungen, Mikrohaerte der einzelnen Mikrophasen und bruchmechanische Parameter ausfuehrlich dargestellt. Die Untersuchungen zeigen die dominierende Rolle des Reckalterungsprozesses bei der Versproedung der Schweissgueter, besonders im Hinblick auf den Stickstoffgehalt und die ziemlich begrenzte Rolle des Spannungsarmgluehens bei solchen Faellen.

    With the goal of constructing a homogeneous data set of moment magnitudes (Mw) to be used for seismic hazard assessment, we compared Mw estimates from moment tensor catalogues available online. We found an apparent scaling disagreement between Mw estimates from the National Earthquake Information Center (NEIC) of the US Geological Survey and from the Global Centroid Moment Tensor (GCMT) project. We suspect that this is the effect of an underestimation of Mw > 7.0 (M0 > 4.0 × 1019 Nm) computed by NEIC owing to the limitations of their computational approach. We also found an apparent scaling disagreement between GCMT and two regional moment tensor catalogues provided by the 'Eidgenössische Technische Hochschule Zürich' (ETHZ) and by the European-Mediterranean Regional Centroid Moment Tensor (RCMT) project of the Italian 'Istituto Nazionale di Geofisica e Vulcanologia' (INGV). This is probably the effect of the overestimation of Mw < 5.5 (M0 < 2.2 × 1017 Nm), up to year 2002, and of Mw < 5.0 (M0 < 4.0 × 1016 Nm), since year 2003, owing to the physical limitations of the standard CMT inversion method used by GCMT for the earthquakes of relatively low magnitude. If the discrepant data are excluded from the comparisons, the scaling disagreements become insignificant in all cases. We observed instead small absolute offsets (≤0.1 units) for NEIC and ETHZ catalogues with respect to GCMT whereas there is an almost perfect correspondence between RCMT and GCMT. Finally, we found a clear underestimation of about 0.2 units of Mw magnitudes computed at the INGV using the time-domain moment tensor (TDMT) method with respect to those reported by GCMT and RCMT. According to our results, we suggest appropriate offset corrections to be applied to Mw estimates from NEIC, ETHZ and TDMT catalogues before merging their data with GCMT and RCMT catalogues. We suggest as well to discard the probably discrepant data from NEIC and GCMT if other Mw estimates from different sources are

    Model observers (MOs) are of interest in the field of medical imaging to assess image quality. However, before procedures using MOs can be proposed in quality control guidelines for mammography systems, we need to know whether MOs are sensitive to changes in image quality and correlations in background structure. Therefore, as a proof of principle, in this study human and model observer (MO) performance are compared for the detection of calcification-like objects using different background structures and image quality levels of unprocessed mammography images. Three different phantoms, homogeneous polymethyl methacrylate, BR3D slabs with swirled patterns (CIRS, Norfolk, VA, USA), and a prototype anthropomorphic breast phantom (Institute of Medical Physics and Radiation Protection, Technische Hochschule Mittelhessen, Germany) were imaged on an Amulet Innovality (FujiFilm, Tokyo, Japan) mammographic X-ray unit. Because the complexities of the structures of these three phantoms were different and not optimized to match the characteristics of real mammographic images, image processing was not applied in this study. In addition, real mammograms were acquired on the same system. Regions of interest (ROIs) were extracted from each image. In half of the ROIs, a 0.25-mm diameter disk was inserted at four different contrast levels to represent a calcification-like object. Each ROI was then modified, so four image qualities relevant for mammography were simulated. The signal-present and signal-absent ROIs were evaluated by a non-pre-whitening model observer with eye filter (NPWE) and a channelized Hotelling observer (CHO) using dense difference of Gaussian channels. The ROIs were also evaluated by human observers in a two alternative forced choice experiment. Detectability results for the human and model observer experiments were correlated using a mixed-effect regression model.

    Rumours have it that the Staedtische Werke der Stadt Kassel paid DM 4 million for reactivation of the 'Neue Muehle' hydroelectric power station. This equals a specifi installed cost of 4 x R10{sup 6} DM/310 kW=12 903 DM/kW. This includes the cost of restoring the historical power station components. The new power plant will provide about 850 - 1000 private households with electric power. It has an expected life of 30 years, and the owner is convinced that the amortisation period will be ten years at the most. [German] In die gesamte Reaktivierung des Wasserkraftwerkes 'Neue Muehle' sollen die Staedtischen Werke der Stadt Kassel angeblich einen Betrag von 4 Mio. DM investiert haben. Damit belaufen sich die stets als brauchbare Vergleichsgroesse dienenden spezifischen installierten Anlagenkosten auf 4 x 10{sup 6} DM/310 kW=12 903 DM/kW. Darin enthalten sind aber hier ausser der reinen Energiegewinnungsanlage, welche in dieser Groessenordnung ca. 850-1 000 Privathaushalte mit elektrischer Energie zu versorgen vermag, auch die restaurierten, dem Denkmalschutz unterliegenden ehemaligen Kraftwerkskomponenten. Der Betreiber rechnet mit einer Lebensdauer von weit ueber 30 Jahren und glaubt mit Sicherheit, dass sich die gesamte Kraftanlage in spaetestens zehn Jahren amortisiert haben wird. (orig.)

  11. 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.)

    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.

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

    The 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.

    Purpose: to evaluate the technical feasibility of the implantation of the monorail RX Herculink trademark system into the renal arteries without pre-dilatation. Materials and methods: forty-two patients (mean age 71 years) from four centers with a total of 44 renal artery stenoses underwent implantation of the RX Herculink trademark stent. The mean grade of the stenosis was 83.8%, the mean length 7.5 mm. The stenoses were ostial in 38 cases and in immediate proximity to the ostium in 6 cases. The mean follow-up-period was 57 weeks (24 - 176 weeks). Results: in 42 cases, the implantation was successful without pre-dilatation. In 2 cases, pre-dilatation was carried out. In none of the cases, detachment of the stent from the balloon was observed. In one stenosis with a length of 17 mm, implantation of two stents was performed. In 9 cases, post-dilatation with a larger balloon or higher balloon pressure was necessary. Residual stenoses exceeding 30% were not observed. Two patients developed local bleeding at the puncture site. During the follow-up, restenoses were observed in 5 stents after 26 to 126 weeks, which necessitated a second intervention in 3 cases (PTA in 2 cases, re-stenting in 1 case). The primary patency rate after 6 and 12 months was 0.92 {+-} 0.056 according to Kaplan-Meier, the secondary patency rate after 6 and 12 months was 1.0 {+-} 0.0. Conclusion: implantation of the RX Herculink trademark stent system into the renal arteries without pre-dilatation is technically feasible and safe. Even without pre-dilatation, the stent-system can be advanced through the stenosis without detachment. The complication rate is low. Our clinical results are comparable to previous studies. (orig.)

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

    The new office building of the Federal Environmental Agency (Dessau-Rosslau, Federal Republic of Germany) was implemented as a pilot project for environmentally sustainable construction with high-energy targets. In order to reduce the consumption of fossil fuels significantly, the building should have a very low power consumption and enable a sustainable operation. A mostly compact form of the building and a highly insulated building envelope are a first prerequisite.

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

    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.)

    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.)

    Overdeepenings, i.e. closed topographic depressions with adverse slopes in the flow direction, are characteristic for glacier beds and glacially sculpted landscapes. Besides their importance as geomorphological landforms, groundwater bodies and sedimentary archives, they are of increasing interest in relation to climate-induced lake formation in de-glaciating landscapes and depth erosion under ice age conditions in connection with the long-term safety of radioactive waste repositories in some mid-latitude countries. Quantitative predictions of their shape, distribution and conditions of occurrence remain difficult. One major problem thereby relates to the still unsatisfactory treatment in glacier erosion theory of sediment evacuation at glacier beds, especially by subglacial meltwater. An alternative way of searching for realistic/empirical quantitative estimates is, therefore, to analyse the geometry of well-documented overdeepenings. The present study attempts to do this by combining statistical analyses of (a) detailed bathymetries from recently exposed lakes in the Peruvian Andes, (b) numerous bed overdeepenigs below still existing glaciers of the Swiss Alps modelled with a robust shear stress approximation linking surface slope to ice thickness at high resolution, and (c, for comparison) reconstructed overdeepenings produced by ice age glaciers in the Swiss Plateau. The sample of (a) has the advantage that geometries are exactly measured and are only subject to young/small sedimentation effects. Sample (b) allows for a comparison with a modern model calculation and with known glacier characteristics. Sample (c) may provide some insights into the question how safely results from high mountain topography can be transferred to sites with markedly different topographic, climatic and glaciological controls (cold-arid lowland). Where possible, mean and maximum values of the parameters surface area, length, width, depth, volume, adverse slope and their statistical interrelations are determined with their corresponding uncertainty ranges. For sample (b) basal shear stress (as used in the model), thermal ice types, glacier size/type, relation to flow characteristics (position along flow, confined-unconfined, confluence-diffluence-channel-forefield) are also included. As principal problem thereby remains the unsolved question of when exactly the overdeepenings had formed (present-day conditions, Holocene maximum stages, ice ages?). Some results nevertheless remain safe. Marked overdeepenings can, for instance, exist under very small cirque glaciers flowing under low shear stresses and having low melt-water input. They can form at confluences but also often occur under conditions of confined flow in rather straight channel configurations. Corresponding lakes can be dammed by huge (terminal) moraines or may form in beautifully polished pure rock beds. The full results of the study are hoped to improve the knowledge basis for practical applications (unmeasured and future lakes, depth erosion by glaciers).

    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.

    In the First Technical Report the fundamental ideas for the realization of this project are presented and the future possible maximum gross employment effects of an expansion of renewable energy systems in North-Rhine-Westphalia with consideration of the present-day cost structure are quantified in an initial stage. In this connection gross employment effects are defined as exclusive positive job effects without consideration of possible negative employment effects on the basis of less investments in other sectors of the economy. Based on a subdivided presentation of the intended course of the project and a formulation of its main objectives, a detailed description of the theoretical background of the applied methods of input-output analysis is provided. After the presentation of some different methods and the necessary assumptions, the analysis takes the so-called `Keynesian income multiplier` into account to accommodate the effects of an increase in national income. To use a known investment distribution, grouped in 21 sub-divisions according to categories of applications, within the scope of an input-output-analysis, the investments are converted. After the determination of the matrices, necessary to quantify employment effects, the maximum possible gross effects concerning the future job market of the Federal Republic of Germany will be assessed with consideration of the fluctuations in productivity on sector level. A total of 700.000 new jobs can be expected, of which about 27% are due to the increase of personal disposable income and the resulting rise in consumer spending respectively.

Technischen Fachbericht werden konzeptionelle Grundlagen zur Realisierung des Vorhabens eroertert und es wird eine erste Abschaetzung der potentiellen Bruttobeschaeftigungswirkungen eines Ausbaus erneuerbarer Energiesysteme in Nordrhein-Westfalen durchgefuehrt. Unter Bruttobeschaeftigungswirkungen werden dabei ausschliesslich positive Arbeitsplatzwirkungen ohne Beruecksichtigung moeglicher negativer Beschaeftigungseffekte aufgrund von Minderinvestitionen in anderen Wirtschaftsbereichen verstanden. Im Anschluss an die gegliederte Darstellung des geplanten Projektablaufs und Formulierung der einzelnen Zielsetzungen wird die fuer die Untersuchung notwendige Methode der Input-Output-Analyse vorgestellt. Neben der Erlaeuterung verschiedener Modelle und der notwendigen Annahmen wird die gewaehlte Analysemethode um den sogenannten `Keynes`schen Einkommensmultiplitkator` erweitert, um auch Auswirkungen eines erhoehten privaten Konsums zu beruecksichtigen.

  18. IN MEMORIAM: Hermann Anton Haus, 1925 2003

    Science.gov (United States)

    2004-08-01

    Photograph Hermann Anton Haus, an Institute Professor at the Massachusetts Institute of Technology (MIT), was to have been a Keynote Speaker at the Fluctuations and Noise in Photonics and Quantum Optics Conference, from which the papers in this special issue derive. Sadly, on May 21, 2003 - less than two weeks before the conference - Professor Haus succumbed to a heart attack after arriving home in Lexington, Massachusetts, from his regular, 15-mile commute by bicycle from MIT. He was 77. Throughout his lengthy and illustrious career, Professor Haus had repeatedly and very successfully addressed problems of fluctuations and noise, with special focus on the fundamental issues that arise in quantum optics. To honour Professor Haus' legacy to our technical community, this special issue of Journal of Optics B: Quantum and Semiclassical Optics is dedicated to his memory. Professor Haus was born in Ljubljana, Slovenia, in the former Yugoslavia, on 8 August 1925. After attending the Technische Hochschule, Graz, and the Technische Hochschule, Wien, in Austria, he received his Bachelor of Science degree from Union College in Schenectady, New York in 1949. In 1951, he graduated from Rensselaer Polytechnic Institute with a Master of Science in Electrical Engineering, and came to MIT, where he earned his Doctorate of Science and joined the faculty in 1954. He was promoted to Associate Professor in 1958, to Professor in 1962, and to Elihu Thomson Professor in 1973. In 1986, he was conferred the honour of Institute Professor. Professor Haus had a lifelong fascination with noise. While still an undergraduate at Union College, he became aware of Norbert Wiener's theories of statistical phenomena - the new mathematics needed to understand and quantify the random fluctuations we refer to as noise. So it was that noise theory formed the core of Professor Haus' research during the 1950s: noise in electron beams, noise in microwave amplifiers, and noise in amplifier cascades. Two of

    In this final report on the research project ''Energy-dispersive study of the interaction of fast neutrons with matter, especially materials for fusion and materials from fission reactors the status reached after three years promotion is described. The aim of this project is the construction and first usage of a very complex time-of-flight system for the study of the interaction of fast neutrons with construction materials for fusion and fission reactors as well as with long-lived radioisotopes. Furthermore astrophysically relevant experiments on problems of the element synthesis shall be performed. The whole project is devided into two sections: 1. Development, construction and test of a pulsed photoneutron source at the ELBE accelerator of the FZ Rossendorf, 2. Application of the photoneutron sources for measurements of cross sections induced by fast, energy-selected neutrons.

    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.)

    All details of the MPA full-scale vessel relevant to non-destructive testing under the Agreement on Scientific and Technological Cooperation were compiled. The BWR pressure vessel (AEG/KWU, material 1.6751-22 NiMoCr 37 - A 508 Cl.2) was complemented by a PWR supporting ring (material 1.6310 - 20 MnMoNi 55). In particular, all documents related to failure insertion and the results of testing programmes carried out so far were evaluated. In addition, two drill cores were taken from the cylindrical lower part and tested metallographically. The test results of three more drill cores and of insertion 95 from the PISC programme were also evaluated. The definite reference data set thus created of the failures selected and studied under the programme of scientific and technological cooperation is set out in a table. It serves as a basis for the evaluation of the test results achieved by the participants in the NDT ring test.

Insbesondere wurden saemtliche Unterlagen ueber die Fehlereinbringung sowie die Ergebnisse der bisher durchgefuehrten Pruefprogramme ausgewertet. Ausserdem wurden zwei Bohrkerne aus dem zylindrischen Unterteil entnommen und metallografisch untersucht. Die Untersuchungsergebnisse von weiteren drei Bohrkernen und des Einschubs 95 aus dem PISC-Programm wurden ebenfalls verwertet. Der so geschaffene, endgueltige Referenz-Datensatz der fuer das WTZ-Programm ausgewaehlten und geprueften Fehler ist tabellarisch aufgelistet.

    Full Text Available Hatte man in den Neunzigerjahren das Netz vor allem als virtuelle Realität charakterisiert, das dem realen Alltag gegenübersteht, so wird immer stärker deutlich, wie stark die Kultur der alltäglichen Lebenswelt mit dem Kulturraum Internet verflochten ist. So wird das Netz, wo man online einkauft, Freunde im Chat trifft, sich täglich über aktuelle Nachrichten informiert, immer mehr als Erweiterung des alltäglichen Lebens betrachtet. Dies bedeutet daher auch, dass wer am Netz aktiv partizipiert, zugleich über einen Anteil an gesellschaftlicher Macht verfügt. Politische Kampagnen im Internet oder die Präsentation von Politikern/-innen bei Wahlkämpfen im Netz unterstreichen diesen Trend auf eindrückliche Weise.

  12. Group Sunspot Numbers: Sunspot Cycle Characteristics

    Science.gov (United States)

    Hathaway, D. H.; Wilson, R. M.; Reichmann, E. J.; Six, N. Frank (Technical Monitor)

    2002-01-01

    We examine the "Group" sunspot numbers constructed by Hoyt and Schatten to determine their utility in characterizing the solar activity cycle. We compare smoothed monthly Group Sunspot Numbers to Zurich (International) Sunspot Numbers, 10.7-cm radio flux, and total sunspot area. We find that the Zurich numbers follow the 10.7-cm radio flux and total sunspot area measurements slightly better than the Group numbers. We examine several significant characteristics of the sunspot cycle using both Group numbers and Zurich numbers. We find that the "Waldmeier Effect" - the anti-correlation between cycle amplitude and the elapsed time between minimum and maximum of a cycle - is much more apparent in the Zurich numbers. The "Amplitude-Period Effect" the anti-correlation between cycle amplitude and the length of the previous cycle from minimum to minimum - is also much more apparent in the Zurich numbers. The "Amplitude-Minimum Effect" - the correlation between cycle amplitude and the activity level at the previous (onset) minimum is equally apparent in both the Zurich numbers and the Group numbers. The "Even-Odd Effect" - in which odd-numbered cycles are larger than their even-numbered precursors - is somewhat stronger in the Group numbers but with a tighter relationship in the Zurich numbers. The "Secular Trend" - the increase in cycle amplitudes since the Maunder Minimum - is much stronger in Group numbers. After removing this trend we find little evidence for multi-cycle periodicities like the 80 year Gleissberg cycle or the two- and three-cycle periodicities. We also find little evidence for a correlation between the amplitude of a cycle and its period or for a bimodal distribution of cycle periods. We conclude that the Group numbers are most useful for extending the sunspot cycle data further back in time and thereby adding more cycles and improving the statistics. However, the Zurich numbers are more useful for characterizing the on-going levels of solar activity.

  14. The alchemy of training.

    Science.gov (United States)

    Egger-Biniores, Deborah

    2007-04-01

    Training in Zurich has its own special character but also is marked by the very fact that it is in Zurich. Zurich radiates its own distinct energy and carries a specific historical significance in the world of analytical psychology. This, like all things with psychic energy, has a spectrum of meaning. This spectrum, as well as the 'spirit' of the place, will be critically examined, taking into account the 'blessings' and 'curses' of such genius loci. Training in Zurich is experientially based and is first and foremost an initiation: an initiation into symbolic life, or rather life where symbol plays an important role. Training is understood to involve a transformation of one's self, much like the 8th century alchemist Morienus Romanus understood the opus as a 'human transformation system'. It is not merely an education. The requirement of 'immersion' is core to the experience of becoming an analyst in Zurich and this sets up a valuable discomfort between rational intellectual learning and intuitive experience, between knowing and not-knowing. How does this dis-serve the making of an analyst? What is implicit in this immersion and its discomfort? Does it have a role in today's emphasis on clinical and empirical training? Does Zurich still offer something unique and valuable in the world of training, or is it passé? From these questions, the dichotomy of what is 'urgent' and 'essential' in training will be examined.

The most common cause of dizziness in the elderly, benign paroxysmal positional vertigo (BPPV, is frequently undiagnosed, and bedside treatment of these patients can be difficult due to neck and back stiffness, which makes repeated and accurate repositioning maneuvers difficult. Case presentation: After a fall, a 96-year-old woman was referred by a resident neurologist for intractable BPPV. The patient was placed on a motorized turntable and repositioned to remove the calcite particles from the affected posterior semicircular canal. Video monitoring of the eyes allowed confirmation of the diagnosis, as well as an immediate evaluation of the effectiveness of the maneuver. Conclusion: Every patient with dizziness or imbalance, even in the absence of typical complaints of BPPV, should be tested with provocation maneuvers, because the clinical picture of BPPV is not always typical. Even if elderly patients with dizziness are very frail, the completion of provocation maneuvers is imperative, since the therapeutic maneuvers are extremely effective. A motorized turntable is very helpful to perform the repositioning accurately and safely. Keywords: vestibulo ocular reflex, nystagmus, vertigo

    Full Text Available Der Einsatz digitaler Medien in formellen Lernzusammenhängen (Schule, Hochschule, berufliche Bildung etc. bietet neue Möglichkeiten, die Kenntnisse und Kompetenzen Lernender darzustellen bzw. abzubilden. So sollen z.B. Instrumente wie E-Portfolios eine selbstbestimmtere Leistungsdarstellung ermöglichen: Lernende sollen ihren Lernprozess dokumentieren und reflektieren, sich ihrer Verantwortung für ihn bewusst werden und ihn im Idealfall selbst steuern, Lehrende nehmen dabei eine beratende und unterstützende Rolle ein. Allerdings sind die Erwartungen und Ansprüche an E-Portfolios sehr unterschiedlich; sie reichen von standardisierten, formalisierten Qualifikationsdarstellungen für den beruflichen Wettbewerbsmarkt bis hin zu individuellen Kompetenzprofilen. Zwar sind in Lehr-Lern-Arrangements weiterhin quantitative Bewertungen von Leistungen weit verbreitet, doch finden sich zunehmend auch qualitative Anteile z.B. durch den Einsatz von E-Portfolios. Dabei werden diese in bestehende Lehr- und Lernkulturen integriert, die sie gleichzeitig verändern. Die Frage ist auch, was mit E-Portfolios erreicht werden soll: Geht es um eine stärkere Förderung der Selbstlernkompetenz und um die Fähigkeit, sich eigenverantwortlich den Forderungen nach lebensbegleitendem Lernen stellen zu können? Sollen individuelle Stärken und Schwächen transparenter werden, um die eigene Reflexion von Bildungsreife wie auch deren Einschätzung und Bewertung durch Ausbildungspersonal zu erleichtern? Oder geht es um beides? Unter dem Oberbegriff E-Assessment dagegen lassen sich computer- bzw. internetgestützte Prüfungsformen (z.B. E-Klausuren zusammenfassen, die anders als E-Portfolios eine möglicherweise objektivere und vergleichbarere Bewertungsgrundlage für die Identifizierung, Darstellung und Reflexion individueller Leistungen bieten.

  8. Wie das Neue in eine Brandenburgische Hochschulbibliothek kommt und nicht versiegen mag – Ein persönlicher Rückblick

    Directory of Open Access Journals (Sweden)

    Frank Seeliger

    2015-11-01

    Full Text Available Das Mantra der Kundenorientierung, Serviceentwicklung und die Verpflichtung zur Effektivität wie Effizienz bei der Bewältigung aller Geschäftsgänge sind mittlerweile Allgemeinplätze. Es verpflichtet Informationseinrichtungen, den aktuellen Entwicklungen und der Zeit auf den Fersen zu bleiben. Was bedeutet dies auf der alltäglich pragmatischen Ebene für eine überschaubare Fachhochschulbibliothek? Eine, die mit wenigen Ressourcen ausgestattet als Showcase, repräsentativer Raum, Boutique sich gut „verkaufen“ muss, um en vogue oder einfach nur relevant und interessant für Stakeholder, Nutzer sowie Mitarbeiter zu bleiben? Auf dem Campus der berlinnahen Informationseinrichtung wird seit dem Neubezug einer denkmalgeschützten Verladehalle 2007 versucht, dem gewinnenden Charme und anmutigen Ambiente des Porticus auch eine herausragende Rolle als Innovations-Hub für die Hochschule und Bibliotheken im Allgmeinen über gelebte neue Ideen abzugewinnen. Sie betreffen sowohl technische Lösungen in Bezug auf RFID, Visualisierung, Automatisierung und Software, aber auch Formate für Veranstaltungen und Weiterbildung. Was ist aber hierfür nötig, um das Neue, gekauft oder selbst gezimmert, immer wieder einfliessen zu lassen und sich mit dem Profil der tatkräftigen und kreativen Avantgarde zu identifizieren? Der Beitrag wird versuchen, das Umfeld dafür zu beleuchten, um Innovationen als selbstverständliche Erwartungshaltung reifen zu lassen. Der deskriptive Ansatz soll nach keineswegs vollständiger Reflexion eigener Bemühungen prima facie Anregung geben dazu, wie im öffentlichen Dienst und ohne direkte Tuchfühlung zu „schwarzen Zahlen“ eine Firmenkultur Einzug halten kann, die bei entsprechender Erwartungshaltung das Unvorhersehbare für sich höher einschätzt als das Vertraute. Es ist ein Plädoyer für das offene System, ein Hoch auf Veränderung und Neues, ohne damit in eine willkürliche Vielfalt zu geraten. Warum kann das

    2000-05-01

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

    Full Text Available Bibliotheken stehen im Spannungsfeld zwischen sich verändernden Erwartungen der potentiellen Benutzer/innen, technologischem Wandel, Sparzwängen und steigenden Kosten für Inhalte und Infrastrukturen. Um fortzubestehen müssen sie sich neu erfinden. Eine Möglichkeit ist es, das Paradigma Offenheit auszufüllen, wonach u.a. die eigenen Kernprodukte entsprechend geltenden Webstandards für jeden frei zugänglich zur Verfügung gestellt werden. Um dies zu erreichen, müssen neue Infrastrukturen aufgebaut und neue Bündnisse eingegangen werden. Der Beitrag geht auf einen Vortrag auf dem Symposium Bibliotheks- und Informationsmanagement der Hochschule der Medien Stuttgart im Dezember 2014 zurück. Libraries are entangled in a mesh of changing demands of potential users, technological advancement, budget cut downs and rising costs for content and infrastructure. In order to survive, they have to reinvent themselves. One option is to adopt the paradigm of openness. This means, among other things, offering the library’s core products free of charge to anyone who can make use of them. This can only be done by implementing new infrastructures and forging new alliances. The article is based on a talk given at a symposium of library and information management in December 2014at the Hochschule der Medien at Stuttgart.

    U.S. District Judge Charles R. Weiner said that a re-reading of the record showed that a policy issued by Zurich Insurance Co. to Sheraton Great Valley Hotel in Frazer, Pennsylvania covered only legal costs. The court determined the insurance policy's language to be ambiguous, but found a preponderance of evidence which showed that the hotel and insurance company negotiated a policy to indemnify the hotel against legal expenses, but not discrimination claims. An earlier judgment had said Zurich was liable for a $155,000 settlement in an HIV discrimination lawsuit.

  19. Agency doctorates

    International Nuclear Information System (INIS)

    1970-01-01

    Staff members of the Agency working at the Seibersdorf laboratory are continuing to achieve high academic distinction. Two more - both Austrian - have now been awarded the degree of Doctor of Agriculture. Joachim Kramer, who is 26, graduated from the Hochschule fur Bodenkultur in 1967 with the degree of Diplom-Ingenieur and then started work in the plant breeding and genetics section of the laboratory under the direction of Dr. Knut Mikaelsen. The results of the research work he carried out were accepted as the subject of a thesis for which he has now been granted his doctorate. The doctoral promotion took place on 30 June, at a ceremony attended by Dr. Andre Finkelstein, Deputy Director General for Research and Isotopes. The subject of Dr. Kramer's thesis was a comprehensive study of the mutagenic effects of fast neutrons and gamma rays, and the influence of various modifying factors such as water content, oxygen and metabolic state of seeds at the time of irradiation. This work has contributed significantly to the understanding of the mechanisms by which these two types of ionizing radiation produce mutations in seeds. The knowledge gained will be of great importance in the efficient use of ionizing radiation in practical plant breeding. Paul Wassermann, who is 33 years old, joined the Agency in 1965. He, too, graduated from the Hochschule fur Bodenkultur as Diplom-Ingenieur in agriculture, having graduated with honours previously from the agricultural secondary school at Raumberg, Austria, in 1958. Dr. Wassermann's own words may be used to explain how he came to gain his doctorate. 'In October, 1966, I completed my studies at the Hochschule,' he writes. 'I was employed at the Agency laboratories in Seibersdorf, working in the plant and soils group. Encouraged by the interesting research which was performed there, a thesis entitled 'the Fate of Nitrogen in Submerged Rice Soils' was started, which finally led to the doctor's degree in Agriculture in June this year

    Full Text Available Seit den 1980er-Jahren haben sich qualitative Forschungsansätze in den Sozialwissenschaften stark verbreitet. In der Medienpädagogik ist dies nicht zuletzt mit einer Hinwendung zu subjektorientierten Ansätzen und Methoden verbunden, die den Fokus der Forschung auf den aktiven Umgang der Menschen mit Medien legen. Seither haben sich die Zugänge und Konzepte der qualitativen Forschung stark differenziert – etwa mit Entwicklungen wie: die Herausbildung konkreter Forschungsprogramme wie grounded theory, die Diskussionen um Gütekriterien der qualitativen Forschung, die Diskussion zur Verbindung von qualitativen und quantitativen Methoden (Triangulation, die Entwicklung von Programmen zur qualitativen Daten- und Inhaltsanalyse, der Hinwendung zu ethnographischen Verfahren, der verstärkte Einbezug visueller Methoden (z.B. Zeichnungen, Foto, Video, die Erneuerung von Konzepten der Aktions- und Praxisforschung, eine Betonung dekonstruktiver Ansätze, die insbesondere die Position der Forschenden thematisieren. In der Medienpädagogik ist mitunter auch argumentiert worden, dass der Stand der methodologischen Entwicklung seit den 1990er Jahren stagniere. Es ist Zeit für die Diskussion der Frage, welche innovativen Verfahren die methodologische Diskussion weiterführen könnten. Das Themenheft «Qualitative Forschung in der Medienpädagogik» geht auf Vorträge auf einer gleichnamigen Tagung zurück, die von der Kommission Medienpädagogik der Deutschen Gesellschaft für Erziehungswissenschaft (DGfE am 22. und 23.

Interventions during acute and post-acute hospital care exist not only to improve short-term outcomes but also to prevent future exacerbations and disease progression. We aimed at measuring the implementation rates of acute and post-acute hospital care interventions for AECOPD.Methods: We performed 24 months (January 1, 2012, to December 31, 2013 retrospective medical chart review of consecutive cases hospitalized to one of three public hospitals in the canton of Zurich due to AECOPD. Implementation rates of five acute care and seven post-acute care interventions were assessed.Results: Data from 263 hospitalizations (61% male, mean age 68.5 years, 47% active smokers were analyzed. The median length of stay was 9 days (interquartile range [IQR] 6–12 days. In all, 32% of hospitalizations were caused by individuals with previous hospitalizations because of AECOPD. Implementation rates of four acute care interventions were >75% (lowest was appropriate antibiotic therapy with 56%. Compared to this, implementation rates of five post-acute care interventions were <25% (lowest was patient education and self-management advice with 2%.Conclusion: The results of this audit revealed room for improvement mainly in post-acute care interventions for AECOPD.

    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)

    Wanke, Carsten; Geworski, Lilli

    2014-09-01

    Clearance monitor systems are used for gross gamma measurements of waste potentially contaminated with radioactivity. These measurements are to make sure that legal requirements, e.g. clearance criteria according to the german radiation protection ordinance, are met. This means that measurement results may overestimate, but must not underestimate the true values. This paper describes a pragmatic way using a calibrated Cs-137 point source to generate a conservative calibration for the clearance monitor system used in the Medizinische Hochschule Hannover (MHH). The most important nuclides used in nuclear medicine are considered. The measurement result reliably overestimates the true value of the activity present in the waste. The calibration is compliant with the demands for conservativity and traceability to national standards. Copyright © 2014. Published by Elsevier GmbH.

    Practical experiences of the phantom method for collection of genital secretions from stallions are reported. Taking a phantom used in the Richard-Götze-Haus Tierärztliche Hochschule Hannover as a prototype two further models slightly modified have been constructed, baring a flat hollow in the right side of the caudal phantom body for manual inserting of the Artificial Vagina. These three models fulfill four important conditions for routine use: (1) sufficient sexual attractivity for the stallions; 80-85% successful collections of presecretions out of a total of 1050 using the dummy and 70% successful semen collections from more than 240 in total; (2) solid and resistant construction; (3) easy cleaning and desinfection of the surface of the phantom to get representative samples; (4) firm installation on a hygienic floor.

    With 20,4 % the syndrome navicular disease has a remarkable part of lameness in the equine fore limb. Although intensive investigations of the last years, there is no uniform opinion in the clinical diagnosis of navicular disease. At first there is a differential description of the diagnosis of navicular disease and a presentation of the importance of this disease from the whole patients of the equine hospital of the Tierärztliche Hochschule Hannover about five years (1980-1984). After that, the importance of the identification of pain with pain provocation test and the elimination of pain by anesthetic nerve blocking are described. The result of the anesthetic block of the ''Ramus pulvinus'' of the medial and lateral palmar digital nerves is a necessary part in clinical diagnosis of navicular disease [de

    Full Text Available Im Freilandgemüsebau sollen einerseits qualitativ hochwertige Produkte erzeugt werden, die frei von Pflanzenschutzmittelrückständen und unerwünschtem Beikrautbesatz sind, andererseits nehmen Indikationslücken bei Herbiziden zu oder die Mittel können unerwünschte Rückstände verursachen. Zunehmend werden daher mechanische Verfahren zur Beikrautregulierung verwendet. Diese sind jedoch sehr zeitaufwendig und somit kostenintensiv. Ob die moderne GPS-Technologie die mechanische Beikrautregulierung unterstützen und optimieren kann, sollte in einer Masterthesis an der Hochschule Geisenheim geklärt werden. Die praktischen Untersuchungen führten zu dem Ergebnis, dass die Beikrautregulierung mittels GPS-Steuerung der Maschinen und Geräte nicht nur schneller, sondern auch kostengünstiger und präziser durchgeführt werden kann.
