    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 Sowohl einzelne Universitäten als auch die Institution Universität als gesamteuropäischer Typus können heute auf eine bis weit in das Mittelalter zurückreichende Kontinuität verweisen. Die Universitäten stellen aber nicht einen geschlechtsneutralen Forschungsgegenstand, sondern eine in vielerlei Hinsicht „gendered organization“ dar. Der Sammelband präsentiert verschiedene Blickwinkel auf diese Geschlechterdimension. Um ‚Gender‘ als Erkenntniskategorie im Verhältnis zur sozialen Organisation Hochschule und zur Geschlechterkultur untersuchen zu können, ist nicht nur eine verbesserte gegenseitige Beachtung von Hochschul- sowie Frauen- und Geschlechterforschung notwendig. Entscheidende Bedeutung kommt insbesondere der reflexiven Wahrnehmung der eigenen „Betroffenheit“ der Hochschul- und der Geschlechterforscher/-innen zu.Many individual universities as well as the specifically European institution of the university can point to a continuity that reaches back well into the Middle Ages. However, universities present not a gender-neutral object of study, but instead in many respects represent a “gendered organization.” The collected volume provides different views on this gendered dimension. In order to study ‘gender’ as a category of knowledge in relation to the social organization of higher education and to gender culture it is necessary that there exist a better mutual respect between research on higher education and research on women and gender studies. Especially the reflexive perception of the way in which the university and gender researchers are themselves affected is accorded crucial meaning.

    Historical records reporting cases of animal anthrax in the canton of Zurich between 1878 and 2005 were analysed on the level of political communities regarding occurrence and number of cases, animals affected, and number of communities affected. Data were correlated with industrial activities (tanning, wool and horse hair processing) in a community and to the prevailing meteorological conditions. A total of 830 cases of animal anthrax has been recorded in 140 of 171 communities. Occurrence correlated with industrial activities in a community such as companies handling potentially contaminated materials (hides, fur, wool, hair, meat, or bone meal). The influence of wool processing companies (P = 0. 004) and tanneries (P = 0. 032) was significant whereas horse hair processing had no effect. However, a statistical relationship between the number of cases reported and meteorological data (rainfall, mean temperature) was not found.

    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.

    Short-chain chlorinated paraffins (SCCPs) are of concern due to their potential for adverse health effects, bioaccumulation, persistence, and long-range transport. Data on concentrations of SCCPs in urban areas and underlying emissions are still scarce. In this study, we investigated the levels and spatial distribution of SCCPs in air, based on two separate, spatially resolved sampling campaigns in the city of Zurich, Switzerland. SCCP concentrations in air ranged from 1.8 to 17 ng·m(-3) (spring 2011) and 1.1 to 42 ng·m(-3) (spring 2013) with medians of 4.3 and 2.7 ng·m(-3), respectively. Both data sets show that atmospheric SCCP levels in Zurich can vary substantially and may be influenced by a number of localized sources within this urban area. Additionally, continuous measurements of atmospheric concentrations performed at one representative sampling site in the city center from 2011 to 2013 showed strong seasonal variations with high SCCP concentrations in summer and lower levels in winter. A long-term dynamic multimedia environmental fate model was parametrized to simulate the seasonal trends of SCCP concentrations in air and to back-calculate urban emissions. Resulting annual SCCP emissions in the city of Zurich accounted for 218-321 kg, which indicates that large SCCP stocks are present in urban areas of industrialized countries.

    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.

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.

  15. Measurements of particulate matter and 3,4-benzopyrene in Zurich

    Energy Technology Data Exchange (ETDEWEB)

    Waibel, M; Wanner, H U

    1974-01-01

    Measurements of particulate matter and 3,4 benzoyrene were carried out at six measuring points in and around Zurich in 1971/72. The measuring points differed according to their immediate surroundings; they were subdivided into industrial zone, heavy traffic spots, residential area, and recreation ground. The correlations were calculated to clarify the connections between emissions and meteorological influences including temperature, inversions, humidity, air pressure, wind strength, visibility, and sunlight. The annual average values for the aerosol concentration were highest (160-181 microgram/cu m) where traffic is very heavy. An industrial center and a residential area of the old part of the city assumed a middle position. The modern residential section of Triemli measured the lowest concentration, 100 micrograms/cu m. The annual average concentrations for BaP were 5.3 ng/cu m for the industrial center, 5.5 and 7/7 ng/cu m for Paradeplatz and Albisriederplatz and 4.1 ng/cu m for Triemli. A high BaP concentration of 6.4 ng/cu m was measured in the old residential section. A correlation between the aerosol concentration of the air and the mortality from stomach cancer was found. Particularly pronounced was the influence of air pollution on mortality due to respiratory diseases. It tripled from the zone with lowest aerosol concentration (less than 80 micrograms/cu m) to the zone with highest air pollution (more than 135 micrograms/cu m). Compared to West German and U.S. cities the aerosol and BaP concentrations measured in Zurich were rather high.

    The transition from the last Ice Age to the early Holocene 15'000-10'000 BP represents a close natural analog to the ongoing and predicted rates of anthropogenic climate change. A reduced quality and quantity of high-resolution proxy archives during this period, however, limits our understanding of the magnitude and pace of Late Glacial (LG) environmental variability. Here, we present the world's best preserved, most replicated and oldest forest remains: A total of 253 subfossil pine stumps were recently discovered in Zurich. The combined approach of tree-ring and radiocarbon (14C) measurements results in an absolutely dated Preboreal Swiss tree-ring width chronology and eight floating chronologies. With tree ages ranging between 41 and 506 years, often including pith and bark, and a mean segment length of 163 years, this exceptional find is distributed over nearly 2'000 years between the Allerød and the Preboreal. Together with 200 previously collected LG pines from the greater Zurich region, this study sets a benchmark in terms of sample replication and dating precision for stable more dynamic climatic periods such as the Laacher See eruption, the Older and Younger Dryas. The paleoenvironmental significance would even increase when annually resolved 14C-measurements help fixing a major, Northern Hemispheric gap in the absolutely dated dendro time series during the Younger Dryas. While overcoming this interlude, our results further emphasize the importance of interdisciplinary research on these striking LG climatic shifts to better understand and assess their ecological and environmental impact.

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

  1. Novel fluid dynamic instrumentation for mixing studies developed at ETH Zurich and PSI

    2009-01-01

    Wire-mesh sensors primarily developed for two-phase flows are known to be useful also for mixing studies in single-phase flows. A prominent example is the boron mixing test facility ROCOM in Rossendorf. ETH Zurich and PSI have started to use wire-mesh sensors for the characterization of the turbulent mixing process in T-junctions, which have gained a considerable relevance to nuclear safety since temperature fluctuations generated by the mixing of fluids of different temperature may cause dangerous thermal loads to the wall material. In the present paper, the application of a high-resolution wire-mesh sensor for the cross-section of the flow duct, combined with a novel wall sensor is reported. The wall sensor is as well based on a conductivity measurement, while the electrodes are manufactured as conducting structures directly flush to the surface of the channel wall. This type of nonintrusive sensor is able to provide information on concentration fluctuations from the boundary layer in experiments where salt tracers are used to substitute the temperature as transport scalar. In an experimental feasibility study it was furthermore shown that both wiremesh sensors and the new wall sensor are sensitive enough to record conductivity changes that are caused by temperature fluctuations in experiments without a tracer salt. This means that benefit can be taken from of high spatial and temporal resolution of both types of sensors to study temperature fluctuations. (author)

  2. Worksite tobacco prevention in the Canton of Zurich: stages of change, predictors, and outcomes.

    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.

    Diel (24-h) concentration variations of polybrominated diphenyl ethers (PBDEs) in air were measured in the center of Zurich, Switzerland, and on Uetliberg, a hill about 5 km from the city center. Air samples were collected simultaneously at both sites over 4 h time periods for 3 consecutive days during a stable high pressure system in August 2007. Higher PBDE concentrations in the city compared to the Uetliberg site indicate that Zurich is a likely source of PBDEs to the atmosphere. A multimedia mass balance model was used to (i) explain the diel cycling pattern of PBDE concentrations observed at both sites in terms of dominant processes and (ii) estimate emission rates of PBDEs from the city to the atmosphere. We estimate that Zurich emits 0.4, 6.2, 1.6, and 0.4 kg year(-1) of the PBDE congeners 28, 47, 99, and 100, respectively. On a per-capita basis, these estimates are within the range or somewhat above those obtained in other studies using approaches based on emission factors (EF) and PBDE production, usage, and disposal data, or concentration measurements. The present approach complements emission estimates based on the EF approach and can also be applied to source areas where EFs and PBDE material flows are poorly characterized or unknown, such as electronic waste processing plants.

    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.

    Kraepelin's partial interpretation of agitated depression as a mixed state of "manic-depressive insanity" (including the current concept of bipolar disorder) has recently been the focus of much research. This paper tested whether, how, and to what extent both psychomotor symptoms, agitation and retardation in depression are related to bipolarity and anxiety. The prospective Zurich Study assessed psychiatric and somatic syndromes in a community sample of young adults (N = 591) (aged 20 at first interview) by six interviews over 20 years (1979-1999). Psychomotor symptoms of agitation and retardation were assessed by professional interviewers from age 22 to 40 (five interviews) on the basis of the observed and reported behaviour within the interview section on depression. Psychiatric diagnoses were strictly operationalised and, in the case of bipolar-II disorder, were broader than proposed by DSM-IV-TR and ICD-10. As indicators of bipolarity, the association with bipolar disorder, a family history of mania/hypomania/cyclothymia, together with hypomanic and cyclothymic temperament as assessed by the general behavior inventory (GBI) [15], and mood lability (an element of cyclothymic temperament) were used. Agitated and retarded depressive states were equally associated with the indicators of bipolarity and with anxiety. Longitudinally, agitation and retardation were significantly associated with each other (OR = 1.8, 95% CI = 1.0-3.2), and this combined group of major depressives showed stronger associations with bipolarity, with both hypomanic/cyclothymic and depressive temperamental traits, and with anxiety. Among agitated, non-retarded depressives, unipolar mood disorder was even twice as common as bipolar mood disorder. Combined agitated and retarded major depressive states are more often bipolar than unipolar, but, in general, agitated depression (with or without retardation) is not more frequently bipolar than retarded depression (with or without agitation), and

    Cities are emission hotspots for both greenhouse gases and air pollutants. They contribute about 70% of global greenhouse gas emissions and are home to a growing number of people potentially suffering from poor air quality in the urban environment. High-resolution atmospheric transport modelling of greenhouse gases and air pollutants at the city scale has, therefore, several important applications such as air pollutant exposure assessment, air quality forecasting, or urban planning and management. When combined with observations, it also has the potential to quantify emissions and monitor their long-term trends, which is the main motivation for the deployment of urban greenhouse gas monitoring networks. We have developed a comprehensive atmospheric modeling model system for the city of Zurich, Switzerland ( 600,000 inhabitants including suburbs), which is composed of the mesoscale model GRAMM simulating the flow in a larger domain around Zurich at 100 m resolution, and the nested high-resolution model GRAL simulating the flow and air pollutant dispersion in the city at building resolving (5-10 m) scale. Based on an extremely detailed emission inventory provided by the municipality of Zurich, we have simulated two years of hourly NOx and CO2 concentration fields across the entire city. Here, we present a detailed evaluation of the simulations against a comprehensive network of continuous monitoring sites and passive samplers for NOx and analyze the sensitivity of the results to the temporal variability of the emissions. Furthermore, we present first simulations of CO2 and investigate the challenges associated with CO2 sources not covered by the inventory such as human respiration and exchange fluxes with urban vegetation.

    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.

    This article discusses the psychological aspects and the technical tactfulness needed when implementing daylight-controlled lighting systems. On the basis of experience gained, the author concludes that the same amount of energy can be saved if the lighting is controlled half-automatically or when the lighting is always switched off when rooms are unoccupied. The article reviews the experience gained with automatically-dimmed lighting in a school in Zurich, Switzerland, and at the University of Zurich. The requirements placed on the control of lighting by the 'Minergie' low energy consumption standard are discussed. Control methods that have been implemented in various public buildings are looked at and the variations in the personal sensitivity of users to varying lighting levels are discussed. The placing of sensors for light-level and occupancy is discussed.

    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.

    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.

    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.

  18. An operational hydrological ensemble prediction system for the city of Zurich (Switzerland: skill, case studies and scenarios

    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

    This contribution first deals with the duality of mercantile and technical plant management systems. The following aspects are considered: reasons for and history of this duality; different approaches taken by mercantile and technical plant management systems; differences in the standardisability of mercantile and technical tasks. Dissolution of the duality through coordinated interplay. The author then goes on to explain the most important components of technically oriented maintenance management. These include the collection of technical plant data (with maintenance-relevant data and relations); the establishment of recurring tasks, the commissioning method (involving occupational safety, packaging and evaluation), compilation of manuals, reporting and accompanying plant documentation. The following tools are useful for DP-assisted maintenance: depiction of organisational and operational structures (authorisation system + IBFS application); workflow systems; modelling (data and object models); navigators; form and dialogue generators; integration of external software (project planning, CAD and Office); interface to mercantile systems. Some highlights of the C/S-IBFS were demonstrated in practice at the symposium.

    An established tool for the assessment of motor performance in children with developmental coordination disorder (DCD) is the Movement-ABC-2 (M-ABC-2). The Zurich Neuromotor Assessment (ZNA) is also widely used for the evaluation of children's motor performance, but has not been compared with the M-ABC-2. Fifty-one children (39 males) between 5 and 7 years of age with suspected DCD were assessed using the M-ABC-2 and the ZNA. Rank correlations between scores of different test components were calculated. The structure of the tests was explored using canonical-correlation analysis. The correlation between total scores of the two motor tests was reasonable (0.66; pABC-2, due to poor performance in the fine motor adaptive component and increased contralateral associated movements (CAM). The canonical-correlation analysis revealed that ZNA measures components like pure motor skills and CAM that are not represented in the M-ABC-2. Furthermore, there was also no equivalent for the aiming and catching items of the M-ABC-2 in ZNA. The two tests measure different motor characteristics in children with suspected DCD and, thus, can be used complementary for the diagnosis of the disorder. Copyright © 2014.

  3. Systems Thinking as a Major Skill of Business Students – A New Teaching Concept at the University of Zurich, Switzerland

    2004-12-01

    Full Text Available In our world of growing complexity, linear thinking and the belief that the whole is only the sum of its parts are evidently obsolete. Systems thinking, which promotes a holistic view of reality, is a situation-adequate handling of complex systems, and is therefore one of the most important skills of future executives in the business world. A new teaching concept was introduced one year ago by the Faculty of Business Administration at the University of Zurich, Switzerland. This concept was designed to help the students to develop abilities in thinking in models, operating complex systems and handling dynamic, non-linear situations. By use of a computer-simulated game the business students should gain knowledge about systemic realities and improve their complex-problem-solving skills. In the semester when the newly designed lecture started, the highly motivated class became aware of the problems in dealing with complexity. Documenting any significant improvements in our students' performance in playing the game was not possible, but we observed a change in their behaviour and ways of thinking in situations of complex problem-solving. Some necessary changes and adjustments in the teaching concept were made and the next class will be investigated in autumn 2003.

    The Zurich Environmental Study (ZENS) is based on a sample of ∼1500 galaxy members of 141 groups in the mass range ∼10{sup 12.5-14.5} M{sub ☉} within the narrow redshift range 0.05 < z < 0.0585. ZENS adopts novel approaches, described here, to quantify four different galactic environments, namely: (1) the mass of the host group halo; (2) the projected halo-centric distance; (3) the rank of galaxies as central or satellites within their group halos; and (4) the filamentary large-scale structure density. No self-consistent identification of a central galaxy is found in ∼40% of <10{sup 13.5} M{sub ☉} groups, from which we estimate that ∼15% of groups at these masses are dynamically unrelaxed systems. Central galaxies in relaxed and unrelaxed groups generally have similar properties, suggesting that centrals are regulated by their mass and not by their environment. Centrals in relaxed groups have, however, ∼30% larger sizes than in unrelaxed groups, possibly due to accretion of small satellites in virialized group halos. At M > 10{sup 10} M{sub ☉}, satellite galaxies in relaxed and unrelaxed groups have similar size, color, and (specific) star formation rate distributions; at lower galaxy masses, satellites are marginally redder in relaxed relative to unrelaxed groups, suggesting quenching of star formation in low-mass satellites by physical processes active in relaxed halos. Overall, relaxed and unrelaxed groups show similar stellar mass populations, likely indicating similar stellar mass conversion efficiencies. In the enclosed ZENS catalog, we publish all environmental diagnostics as well as the galaxy structural and photometric measurements described in companion ZENS papers II and III.

    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. In diesem Buch wird zunaechst die Methodik der Modellermittlung und -beschreibung dargelegt, aus welcher ein breit anwendbarer Grundalgorithmus abgeleitet worden ist. 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.)

    Therapy dosemeters are subject to calibration as from January 1, 1983 according to section 3 of the second ordinance concerning the obligation to calibrate measuring instruments (in the version of the ordinance concerning the amendment of the second and third ordinance about the obligation to calibrate measuring instruments of December 21, 1979, Federal Gazette I p 2347). Section 4 subsection 2 of this ordinance determines a transitional period until December 31, 1985. In this transitional period those therapy dosemeters may be used without calibration which were already in use on January 1, 1983. The requirements of the PTB correspond to the established rules of technology. They specify and complete the provisions of the standardization regulations and establish terms and conditions of the test. They passed the general assembly of the Physikalisch-Technische Bundesanstalt concerning calibration and measurement of 1982. The requirements of the PTB stipulate the admissible limits for effects of numerous influencing factors and other properties of the equipment and tolerances of calibration and handling. (orig.) [de

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

    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.)

    Problems in gender expectations and relationships complicated increasing professionalization of medical arts at an important point of transformation toward the modern industrial European state. Subordination of women's work in these processes altered possible outcomes for German society in general and for female medical careers in particular. Franziska Tiburtius was one of twenty German women who graduated from the coeducational medical school in Zurich, Switzerland, in the nineteenth century. She was a founder of the Clinic of Women Doctors despite prohibitions against certifying women as physicians. Imperial Germany was the last Western nation to admit women to full medical practice in 1899.

    1986-06-01

    Air pollution with Pb, Cu, Zn and Cd in the Zurich region was monitored by analyzing 196 moss samples. The metal concentrations were evaluated with the method of differential pulse anodic stripping voltammetry (DPASV) after the samples had been thoroughly washed and after extraction with 2N nitric acid. Nine samples of the same moss species from a rural region with similar climatic conditions were used as comparison material. The average values of the urban region were higher by 6 times for Cd, 10 times for Pb, 12 times for Cu and 17 times for Zn than in the region of comparison. It was found that the emissions from traffic, from areas of high building density (e.g. domestic heating exhaust, erosion of building material) and from incineration plants were responsible for between 36% (Zn) and 62% (Pb) of the total variance (p < 0.05). The largest percentage of variance for all four metals can be attributed to the parameter traffic.

Die Einzelergebnisse bieten eine gute Orientierung; auf der theoretischen und konzeptionellen Ebene der Geschlechterforschung und der Geschlechterpolitik in der Hochschule ist jedoch kritisch anzumerken, dass unterschiedlichen Traditionen folgende Genderbegriffe und politische Strategien unvermittelt zusammengestellt werden, ohne deren Genealogien und politischen Kontexte zu reflektieren.

The individual findings offer a good orientation; however, regarding the theoretical and conceptual level of gender research and gender politics at the universities, it has to be noted critically that gender concepts and political strategies from varying traditions are put together abruptly without reflecting on their genealogies and political contexts.

    In hoch entwickelten Industrieländern stehen laut Weltgesundheitsorganisation (WHO) Herz-Kreislauf-Erkrankungen und speziell die Koronare Herzkrankheit (KHK) an erster Stelle der Todesursachen. In Deutschland betrug die Zahl der erfassten, an KHK erkrankten Personen ohne Berücksichtigung der Dunkelziffer allein im Jahre 2001 über 473.000. Die KHK war im Jahre 2003 mit 92.673 erfassten Todesfällen immer noch die häufigste Todesursache, obgleich in Deutschland die Häufigkeit der Koronarinterventionen zur Behandlung der KHK zwischen 1984 und 2003 um fast das 80fache von 2.809 auf 221.867 Eingriffe pro Jahr gestiegen ist [1]. Neben der hohen Zahl an Todesfällen haben die betroffenen Personen durch chronische Schmerzen und eingeschränkte körperliche Leistungsfähigkeit zusätzlich eine starke Beeinträchtigung der Lebensqualität [2].In Folge dessen wird die erkrankte Person häufig zum Pflegefall was neben den gesundheitlichen Aspekten auch eine sozioökonomische Komponente in Form der fehlenden Arbeitskraft und den auftretenden Pflegekosten nach sich zieht. Die Kosten für die Behandlung der KHK in Deutschland beliefen sich im Jahre 2002 laut Statistischem Bundesamt auf rund 6,9 Mrd. €.

    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.

    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.

    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.

    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.

    Following current socio-ecological hypotheses, the social organisation of a species is mainly determined by resource quality and distribution. In the case of Microcebus spp., a taxon-specific socio-ecological model was formulated earlier to explain their variable social organisation. The aim of this study was to test predictions from this model in Goodman's mouse lemur based on a data set from animals living in the semi-free colony of Zurich Zoo. During a 2-month study, we observed 5 females and 5 males using radiotelemetry. We collected data on space use and social behaviour, on sleeping sites and on sleeping group composition. Predictions were only partly confirmed. As expected, Goodman's mouse lemurs were solitary foragers with an increased level of sociality due to crowding effects at the feeding stations. In contrast to the prediction, females and males formed unisexual sleeping groups, which were stable in females and of a fission-fusion type in males. Whereas the formation of sleeping groups by both sexes may be triggered by thermoregulatory benefits, the formation of unisexual sleeping groups may result from divergent interests of the sexes. We conclude that the existing model for the evolution of mouse lemur social organisation needs to be refined. Copyright © 2013 S. Karger AG, Basel.

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

    Efficient storage of electrical energy is an increasing need. New developments in high-power electronics, high-strength materials and magnetic bearings have made efficient reliable flywheel mass storage systems in the range of 1-5 MfW/50-150 kWh conceivable. According to a first assessment, these systems may provide energy to the supply grid in a range of seconds and thus ensure frequency maintenance and compensation of short interruptions. The authors present first results of a preliminary study preparatory to a feasibility study on the technical and economic practicability of flywheel mass storage systems. (orig.) [Deutsch] Das Thema effiziente Speicherung von elektrischer Energie gewinnt immer mehr an Bedeutung. Durch neuere Entwicklungen in der Leistungselektronik und bei der Herstellung hochfester Werkstoffe sowie durch Fortschritte bei der Entwicklung von beruehrungsfreien Lagern im Bereich der aktiven Magnetlager (AML) und insbesondere supraleitenden Magnetlager (SML) sind effiziente und sichere Schwungmassenspeicher-Systeme (SMSS) bis in die Bereiche 1-5 MW/50-150 kWh denkbar. Nach einer ersten Einschaetzung eignen sich solche Anlagen, um im Sekundenbereich Energie in das Netz abzugeben und somit zur Frequenzstuetzung und zur Kompensation von Kurzunterbrechungen beizutragen. Praesentiert werden erste Ergebnisse einer Untersuchung zur Vorbereitung einer Machbarkeitsstudie ueber die technisch-wirtschaftliche Realisierbarkeit von Schwungmassenspeicher-Systemen. (orig.)

    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.

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

    Within the POOLTHY Project of the European Union (Euratom Fourth Framework Programme contract FJ4J-CT95-0003) an active/passive concept (SUCO-Programme) was investigated which controls the heat removal after a potential core melt-down accident in an evolutionary light water reactor by spreading and stabilising the core melt in the reactor sump and flooding the melt with sump water from above. The experiments were performed in the test facility SUCOT which was designed and erected at the Institute for Nuclear and Energy Technologies (IKET). The report gives an overview on the SUCO-Programme and the scaling analysis, which was applied to design the test facility SUCOT. A detailed technical description of the test facility SUCOT is given, in which the natural circulation driven two-phase flow within the reactor sump and relevant phenomena such as flow boiling, disperse bubbly flow with and without mass transfer, and geysering are investigated. The major components of the test facility, the three-loop system and the instrumentation are described. Finally, a perspective for future application of the gained knowledge is given. (orig.)

    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.

    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.

    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.

    Different oil condensing boilers, which were available on the German market, have been investigated in order to determine the relevant limit for sulphur content in domestic heating oil. Up to now, the condensate from oil condensing boilers has to be neutralized in many cases due to local legislation. The composition of the condensates from oil boilers came out to be similar to the condensate from gas condensing boilers, as long as the sulphur content of heating oil is below 100 mg/kg. As the neutralization of condensate from gas condensing boilers is usually not required up to 200 kW-boilers, there should be no technical reason for neutralization, as long as the sulphur content is below 100 mg/kg. However, boiler manufactures are convinced, that only if the sulphur content is as low as 50 mg/kg, it will be possible to develop reliable oil condensing boilers for a reasonable price. Calculations of the total energy consumption came to the result, that primary energy can be saved. The increase of efficiency on the boiler side has more influence than the energy needed for desulphurization. (orig.) [German] Zur Bestimmung eines technisch begruendeten Schwefelgrenzwertes fuer ein neues 'schwefelarmes' Heizoel EL wurden Untersuchungen mit Heizoelen unterschiedlichen Schwefelgehaltes an verschiedenen auf dem Markt verfuegbaren Oelbrennwertgeraeten durchgefuehrt. Zur Zeit wird durch das ATV Arbeitsblatt A-251 eine Neutralisation von Kondensaten aus Oelbrennwertanlagen gefordert. Die Untersuchungen zeigen, dass bei Schwefelgehalten unter 100 mg/kg die Kondensate aehnliche Zusammensetzungen aufweisen wie Kondensate aus Gasbrennwertgeraeten. Die Voraussetzung fuer eine Befreiung von der Neutralisationsverpflichtung bei der Verwendung dieser Brennstoffe ist damit aus technischer Sicht gegeben. Fuer die Entwicklung von neuen, kompakten und preiswerten Oelbrennwertgeraeten wird von der Heizgeraeteindustrie ein Schwefelgehalt von max. 50 mg/kg fuer notwendig gehalten

    In the framework of Project RODOS (Real-Time On-Line Decision Support System for Nuclear Emergencies in Europe), the European Atomic Energy Community (EAEC) of the Commission of the European Communities has commissioned the development of a unified concept, body of knowledge, models and software package meant to assist the evaluation of the source term of severe nuclear accidents in light water reactors of the types prevailing on the Continent. Code-named STEPS, for 'Source Term Estimation based on Plant Status', the project has evolved as Contract RODOS D (FI4P-CT96-0048), between EAEC and consortium of expert European centres including Commissariat a l'Energie Atomique, Institut de Protection et de Surete Nucleaire, (CEA-DPI-SEAC) as Coordinator and Forschungszentrum Karlsruhe GmbH (FZK-INR), the Finnish Centre for Radiation and Nuclear Safety, (STUK-NSD), the Technical Research Centre of Finland, Energy, Nuclear Energy (VTT-ET-NE), and Eidgenossische Technische Hochschule - ETH Zurich, Centre of Excellence (ETH-CERS) as Contractors. For the Phase 0 of the project, an IFIN-HH expert has been assigned by ETH-CERS to develop the Technical Specifications of the delivery component of the intended STEPS package, the CONTAINMENT Module. Sponsored by ETH-CERS headquarters in Zurich, the work was done on the premises and with the logistic support of CEA D PI-SEAC at Fontenay-aux-Roses, with the feedback processing and computer code development subsequently performed in Bucharest. The Technical Specifications of the STEPS CONTAINMENT Module were guided by specific terms of reference, including: (i) the capability of the software to function as a source term interface between targeted nuclear power plants and the RODOS System; (ii) the comparable capability of the system to be operated as a stand-alone assessment and decision support tool for a comprehensive variety of plants, nuclear emergency classes. On the technical side, the specifications had to focus on the possible

    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.

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.

    'Technical progress safeguards future', the guiding theme of the 1985 conference of German engineers, calls for discussion. In five lectures representatives of the subdivisions of 'VDI' issued their statements from the viewpoints of their special fields. These lectures were completed by reports on the part of the remaining VDI subdivisions, which are published together with the lectures in this volume. The complex guiding theme is meant to stimulate discussion, which should be conducted also with representatives of other sciences and the public. The volume contains a.o. contributions regarding future prospects, given certain modifications in construction engineering and user behaviour in the sector heating and air-conditioning, regarding the development of new construction techniques to protect the environment, and regarding clean air as an international concern of engineers. For these three contributions separate entries were made. Other presentations relate to: automobile production technology; energy supply as an engineering task; information, invention, innovation as stages of technical progress; progress in materials technology; noise of motor vehicles - current state and future prospects.

    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

  19. 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.

    1981-01-15

    The analysis of depressurisation accidents requires the use of digital computer programs to find out the dynamic loads acting on the plant structures. Because of the importance of such accidents in safety and licensing procedures of nuclear process heat plants, it is necessary to compare these computer results with suitable experiments to show the accuracy and the limits of the programs in question. For this purpose a series of depressurisation experiments has been started at INTERATOM on a small scale model of a primary loop of a nuclear process heat plant. Using the results of these experiments three different computer programs were tested with good success. The development of the experimental program and the estimation of the results was carried out in co-operation with KFA-Juelich and the Technische Hochschule Aachen.

    While testing a new antenna control software tool, the telescope was moved to the most western azimuth position pointing to our own building. While de-accelerating the telescope, the spectrometer showed strong broadband radio frequency interference (RFI) and two single-frequency carriers around 1412 and 1425 MHz, both of which are in the internationally protected band. After lengthy analysis it was found out, that the Webcam AXIS2000 was the source for both the broadband and single-frequency interference. Switching off the Webcam solved the problem immediately. So, for future observations of 21 cm radiation, all nearby electronics has to be switched off. Not only the Webcam but also all unused PCs, printers, networks, monitors etc.

    Violent behaviour associated with alcohol consumption is frequently reported by different media. Clinical data analysing the correlation between alcohol intoxication, age, gender and violence are scarce. The aim of this study was to evaluate the influence of age, gender and blood alcohol content on violent behaviour under the influence of alcohol under central European conditions. Three hundred patients admitted to the emergency department were included into this study in the time period from January 01. to December 31. 2009. The inclusion criteria were a blood alcohol content (BAC) of ≥10 mmol/l, any traumatic injury and an age ≥16 years. Violence was defined as an evitable act committed by others leading to patient's hospitalisation. The data were compared with Wilcoxon and χ2-test for proportions. The data were considered as significant if pviolence with no correlation to blood alcohol content found. Logistic regression analysis revealed male gender and young age as an independent predictor for violence. These results clarify the relationship between alcohol, age, gender and violence and have important implications for municipal-level alcohol policies.

    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 {sup 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.)

    2011-06-01

    The European General Practice Research Network held an international research meeting on 'Motivation in medical education and patient communication' in Zürich, Switzerland, in October 2010. The two authors were keynote speakers, who introduced the theme from different angles and summarized and reflected on individual papers presented at the conference. The theme of the conference underlined the importance of communication in general practice and of motivation in medical education in particular. There were a variety of papers each addressing in its own way the topic of this meeting. We conclude that it is still uncommon to use psychological theories on motivation in research on motivation and patient communication in general practice/family medicine. Motivation and readiness to change are essential concepts in experimental health services research. Research designs increasingly follow the Framework for the Evaluation of Complex Interventions in Health Care as suggested by the British Medical Research Council. However, there are also difficulties related to classical experimental designs that have to be critically discussed.

    Our aim in this paper is to explain the international strategies of cities by focusing on market conditions. Drawing on a critique of the glocalisation thesis we show that the design of these strategies can plausibly be explained by the specific characteristics of urban capitalism found in the different cities. Whereas the international strategy of Manchester must be seen as a response to problems of postindustrial restrictions, the importance of the logistic sector in Dutch capitalism strong...

    Full Text Available Psychotherapy is often regarded as a technique by which convicts can be changed in accordance with the wishes of society. Independent client activity is paid too little attention to. However, it is the one on which it depends whether the therapeutic work will begin, as well as the extent to which the client will be able to transfer the acquired in the course of the therapy awareness so that it can last after his release from a prison. In order to check how deep the mental changes are, you can use some analytical therapeutic approaches that help the therapist to control the process. Therapeutic interventions of different psychological schools make it possible to enhance a customer and to stimulate his activity

    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.

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

    International Nuclear Information System (INIS)

    1983-02-01

    The works in the Institute for Technical Physics (ITP) concentrated in 1982 upon the application of high current superconductivity in the fields of energy engineering and fusion. Moreover, the magnet technology for use in other fields of research and technology is advanced. Fundamental investigations on cryogenics and superconductors as well as studies go along with the technical research program. The magnetic fields of stationary and quasi-stationary fusion reactors with magnetic confinement have to be produced by superconductivity. The aim of the magnet developments in the KfK is therefore to make available the technology of superconductivity for large-scale experiments in plasma physics and the later fusion reactors, which is performed in co-operation with industry as part of the European fusion program.

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

    1986-01-01

    The fourth edition of the 'Technical regulations - district heating service connections' constitutes a completely revised version answering to the considerable developments and changes the house service sector experienced between 1975 and 1985. Analyses and practical experiences have proved to show that precision thermostats which, depending on the mode of lines and layout of the service system allow to spare central temperature control systems, still have a decisive influence on the design of district heating service stations. The revised chapter on steam line service connections focuses on problems concerning the metering of condensates and the connection of secondary water heating networks to steam lines. The reader finds an updated selection of diagrams as well as a revised appendix listing the AGFW codes of practice and recommendations, relevant DIN standards and relevant VDE/VDI recommendations.

    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.

    The series of lectures which forms the basis of this book and took place in the winter of 1989/90 at the ETH in Zuerich were held for the purpose of discussing the stage of development of our system of ethics in view of the extremely fast pace of technological progress and the risks which accompany it. Legal, psychological and political aspects of the problem were examined, but the emphasis was placed on ethical aspects. The effects which are examined in conventional risk analyses can be considered as a part of the ethical and social aspects involved, and in turn, the consideration of ethical and social aspects can be viewed as an extension of the conventional form of risk analysis. In any case, among risk experts, the significance of ethical and social factors is uncontested, especially as regards activities which can have far-reaching repurcussions. Some objective difficulties interfere with this goal, however: - No generally acknowledged set of ethical values exists. - Cultural influences and personal motives can interfere. - Normally a risk assessment is carried out in reference to individual facilities and within a small, clearly defined framework. Under certain circumstances, generalizations which are made for complete technological systems can lead to completely different conclusions. One contribution deals with integral views of the risks of atomic energy from an ethical and social perspective. (orig.).

    Although it is a familiar subject, biochar is highly topical. The reasons are climate protection measures and the security of resources. Both the energy-intensive primary industries, such as steel, cement- and lime plants, as well as the operators of fossil-fueled power plants, particularly coal-fired power stations, have a fundamental and economically motivated interest in climate-neutral and competitively priced energy resources. For economical causes and in relevance to the climate, the focus of biochar production should be on the use of biogenic waste material. In principle, two different methods are applied to produce biochar. One is through pyrolysis, meaning heating and devolatilization of the material under the exclusion of air, and the other one is through hydrothermal treatment of biomasses in aqueous phase under high pressure and elevated temperatures. Basically, biochar with high carbon content and a low amount of volatile matter is suitable for almost every industrial process, in which coal or coke are used as reducing agents, e.g. metallurgical processes, such as iron and steel production. In order to use biochar as a fuel, a lower level of quality is sufficient. In this case, the main aim of the thermal treatment is to increase the energy density of biomass.

This evolution of technology seemed able to explain multi-causal coherences in the genesis of technology applicably by using allegedly simple rules.

    This final report for the Swiss Federal Office of Energy (SFOE) presents the results of a project aimed at providing proof that the energy needs of an four-storey apartment house built to so-called 'passive-house' zero-energy-consumption standards could be met using energy from a photovoltaic (PV) installation integrated in the building's metal roof. The building's energy-relevant characteristics are briefly presented and its 300 m{sup 2} roof with its 504, 32 W{sub p} amorphous triple-cell solar panels is described. The performance of the photovoltaic installation is analysed. The system supplies excess power to the electricity mains in summer which is then drawn again in winter. Each apartment has its own segment of the PV installation. Figures are presented on total solar power production and on data collected for one of the apartments with respect to comfort and electricity consumption.

  14. Procedure for the direct numerical simulation of turbulent flows in plane channels and annuli and its application in the development of turbulence models

    Energy Technology Data Exchange (ETDEWEB)

    Schumann, U

    1973-10-01

    Thesis. Submitted to Technische Hochschule, Karlsruhe (West Germany). A numerical difference scheme is described to simulate threedimensional, time- dependent, turbulent flows of incompressible fluids at high Reynolds numbers in a plane channel and in concertric annuli. Starting from the results of Deardorff, the NavierStokes equations, averaged over grid volumes, are integrated. For description of the subgrid scale motion a novel model has been developed which takes into account strongly inhomogeneous turbulence and grid volumes of unequal side lengths. The premises used in the model are described and discussed. Stability criteria are established for this method and for similar difference schemes. For computation of the pressure field the appropriate Poisson's equation is solved accurately, except for rounding errors, by Fast Fourier Transform. The procedure implemented in the TURBIT-1 program is used to simulate turbulent flows in a plane channel and an annulus of 5: 1 ratio of radii. For both types of flow, different cases are realized with a maximum number of grid volumes of 65536. For rather small grid volume numbers the numerical results are in good agreement with experimental values. Especially the velocity profile and the mean velocity fluctuations are computed with significantly better accuracy than in earlier, direct simulations. The energy --length-scale model and the pressurestrain correlation are used as examples to show that the method may be used successfully to evaluate the parameters of turbulence models. Earlier results are reviewed and proposals for future research are made. (auth)

    In the Closing Remarks at the Symposium on 'Frontiers in Bioorganic Chemistry' (Friday, February 6, 2009, Pharmacenter, University of Basel) in honour of Daniel Bellus, his arrival in Zürich in fall 1967 and especially his postdoctoral work at the Laboratorium für Organische Chemie at the Eidgenössische Technische Hochschule (ETH) in Zürich throughout the year 1967/68 were mentioned. In his most remarkable paper (published in 1969 in Helv. Chim. Acta), the photochemistry of the alpha,beta-unsaturated cyclohexenones O-acetyl-testosterone and 10-methy-delta1,9-octalon-(2) is described in detail. Change of solvent leads to lowering or increasing of the n,pi*- and (pi,pi*)-triplet energies, resulting in a crossing of the two energy levels. Personal remarks on Daniel Bellus and warmest thanks to him, to Profs. Beat Ernst and Bernd Giese (the organizers of the symposium) and to all the speakers concluded this most special event.

    2010-09-15

    We present a small single camera imaging system that provides a continuous 280{sup 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.

    1987-01-01

    Numerical methods are developed for control of three dimensional adaptive test sections. The physical properties of the design problem occurring in the external field computation are analyzed, and a design procedure suited for solution of the problem is worked out. To do this, the desired wall shape is determined by stepwise modification of an initial contour. The necessary changes in geometry are determined with the aid of a panel procedure, or, with incident flow near the sonic range, with a transonic small perturbation (TSP) procedure. The designed wall shape, together with the wall deflections set during the tunnel run, are the input to a newly derived one-step formula which immediately yields the adapted wall contour. This is particularly important since the classical iterative adaptation scheme is shown to converge poorly for 3D flows. Experimental results obtained in the adaptive test section with eight flexible walls are presented to demonstrate the potential of the procedure. Finally, a method is described to minimize wall interference in 3D flows by adapting only the top and bottom wind tunnel walls.

    Anyone creating sources of danger in a public place must take proper precautions to prevent a hazard from actually arising. Work such as the construction or renovation of generating plants, pipe networks or district heat substations, the operation of heating installations and plants and the use of heating water and steam as media for the supply or district heating are potential sources of danger which may lead to accidents. The utility is liable for material damage and bodily harm. The only possible way of precluding liability is to prove that it has taken all possible measures for precluding risk at the outset within the organization itself, to the greatest possible extent. Not only must administration and line management be properly structured for this purpose, but administrative efficiency must also be demonstrated by a working system of delegation of tasks and responsibilities and the optimum organisation of processes and interfaces.

    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.

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

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

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

    Even today, after 65 years of operation, the Wettingen hydroelectric power plant of EWZ still retains many of its original components. They are technically obsolete and need to be replaced. Investments to be made by the municipal works of Zurich (EWZ) are of the order of magnitude of 60 to 70 million Swiss francs. These investments will not have paid back by the time the franchise expires in 2013; therefore, the city of Zurich is negotiating with the two franchise givers, the canton governments of Aargau and Zurich, seeking to obtain premature renewal of the franchise under which it is entitled to use the water rights. Thanks to the installation of a new turbine in the retaining weir, it will then be possible to increase residual water flow over the distance of 1300 metres twelve to twenty-fold. (orig.) [Deutsch] Noch heute, nach 65 Betriebsjahren, bestehen viele Anlageteile des EWZ-Flusskraftwerks Wettingen im Originalzustand. Sie sind technisch veraltet und muessen deshalb erneuert werden. Die geplante Erneuerung erfordert vom Elektrizitaetswerk der Stadt Zuerich (EWZ) Investitionen in der Groessenordnung von 60 bis 70 Millionen Franken. Da sich diese Investitionen bis zum Ablauf der Konzession im Jahre 2013 nicht amortisieren lassen, verhandelt die Stadt Zuerich mit den beiden Konzessionsgebern, den Kantonen Aargau und Zuerich, um eine vorzeitige Erneuerung der Konzession zur Nutzung der Wasserrechte zu erhalten. Dank dem Einbau einer neuen Dotierturbine im Stauwehr wird es dann moeglich sein, die Wasserfuehrung in der 1300 m langen Restwasserstrecke auf das Zwoelf- bis Zwanzigfache des heutigen Wertes zu erhoehen.

    Compact, low energy accelerator mass spectrometry (AMS) has evolved over the past years as one of the most sensitive, selective, and robust techniques for the analysis of heavy and long lived radionuclides. In this study, we will first focus on the analytical capabilities of the compact AMS system TANDY, mainly for {sup 236}U analyses, and then present a new dual tracer approach, that combines {sup 129}I and {sup 236}U. The measured {sup 129}I/{sup 236}U ratios of samples collected in the North Sea in 2009 are in reasonable agreement with the expectations from documented or estimated releases from the two major nuclear reprocessing plants located at Sellafield (GB) and La Hague (F), suggesting that the {sup 129}I/{sup 236}U ratio can be used as a water mass tag in the North Atlantic region. However, our results indicate that, in contrast to {sup 129}I, additional contributions of bomb produced {sup 236}U cannot be neglected in the North Sea region. This complicates the simple and straight forward use of the {sup 129}I/{sup 236}U ratio as a quantitative tool for the calculation of transport times of North Sea water in the Arctic Ocean.

    This lectures aim at giving graduate students an introduction to a working knowledge of path integral methods in a wide variety of fields in physics. Consequently, the the lecture notes are organized in three main parts dealing with non-relativistic quantum mechanics, many-body physics and field theory. In the first part the basic concepts of path integrals are developed in the usual heuristic, non-mathematical way followed by the standard examples of quadratic Lagrangians for which the path integrals can be solved exactly. Applications include semi-classical expansions, scattering problems and the representation of Green functions as path integrals. In the last chapter of this part it is shown how (euclidean) path integrals can be treated numerically by Monte-Carlo methods with a program for the anharmonic oscillator as an explicit example. The second part deals with the application of path integrals in statistical mechanics and many-body problems. Various chapters treat the partition functions, the polaron problem as a non-relativistic field theory and path integrals over ordinary and Grassmannian coherent states. Perturbation theory and the diagrammatic rules are derived in an unified way for both bosons and fermions and illustrated by simple examples. Finally, in the third part path integrals in relativistic quantum field theory are discussed. Standard topics like the generating functional for Green functions, perturbative expansions, effective actions and quantization of gauge theories are treated. Some special applications (the wordline formalism and spin in relativistic path integrals, the derivation of anomalies by path integral methods) are contained in additional chapters. The last section tries to give a simple introduction into lattice (gauge) field theory including a numerical example which can be run on a PC. The set of problems which accompanied the lectures is also included in the present notes. (author) 15 figs., refs.

    This illustrated article describes the new headquarters of the International Federation of Football Associations (FIFA). The headquarters, named 'the home of FIFA', is a zero-emission building complemented by a full-size football field, a training field and a beach-soccer field. Its modern architecture features a hanging glass sheath as part of a double-facade concept. The article takes a look at the concept behind this six-floor building, four of which are actually below ground. Air-conditioning and other building technical services are described and, in particular, details are given on the construction of the building's aluminium and glass facades. Insulation values and the climatic conditions to which the facades are exposed are discussed. Illustrations of constructional details are given.

    Full Text Available 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.

    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 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

  11. 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.

    Kalvius, G. M.; Kienle, P.

    Mössbauer and one of the authors (PK) started in 1949 studying physics at the Technische Hochschule München (THM), which was still under reconstruction from the war damages. It offered two directions for studying physics: "Physik A" and "Physik B." I took courses in "Physik A," which meant Technical Physics; Mössbauer studied "Physik B," which was General Physics. Actually, the lectures of both directions were not too different up to the forth semester, followed by a "pre-diploma" examination, which Mössbauer passed in 1952. I as "Physik A" student had besides the various physics, chemistry, and mathematics courses, in addition lectures in Technical Electricity, Technical Mechanics, Technical Thermodynamics, and later Measurement Engineering offered by very famous professors, such as W.O. Schumann, L. Föppl, W. Nußelt, and H. Piloty. Our physics teachers were G. Joos (Experimental physics), G. Hettner (Theoretical Physics), and W. Meissner (Technical Physics); in mathematics, we enjoyed lectures by J. Lense and R. Sauer, and interesting chemistry lectures by W. Hieber. Thus we received a high-class classical education, but quantum mechanics was not a compulsory subject. Mössbauer complained about this deficiency when he realized that the effect he found was a quantum mechanical phenomenon. Quantum mechanics was offered as an optional subject by Prof. Fick and Prof. Haug. Mössbauer just missed to take these advanced lectures, although he was highly talented in mathematics and received even a tutoring position in the mathematics institute of Prof. R. Sauer, while I worked in engineering projects and had extensive industrial training.

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

    Operation management is not restricted to the execution of operational measures. In order to be able to work together efficiently the different organisational units of a plant are dependent on the support of an intelligent operation management system. Such an operation management system must give the user`s working style priority over the system`s integration in the superordinate system. This is the only way to win the user`s acceptance and achieve the intended results now and over the long term. The most important thing to consider when planning the introduction of an operation management system are the likely processing costs. The one-time cost of procuring the necessary software is practically negligible. [Deutsch] Betriebsfuehrung ist keine ausschliesslich auf die Abwicklung der betrieblichen Massnahmen ausgerichtete Aufgabe. Die Organisationseinheiten des Betriebes muessen zur rationellen Bearbeitung durch ein intelligentes Betriebsfuehrungssystem unterstuetzt werden. Dieses Betriebsfuehrungssystem hat die Arbeitsweisen der Anwender vor die Integration des Systems in uebergeordnete Gesamtsysteme zu stellen. Nur so kann die Akzeptanz der Anwender erzielt sowie das geforderte Ergebnis erreicht und langfristig gesichert werden. Bei der Einfuehrung eines Betriebsfuehrungssystems sind insbesondere die langfristig zu erwartenden Bearbeitungskosten zu bewerten. Die einmaligen Anschaffungskosten der Software sind in Relation zu den Gesamtkosten praktisch ohne Bedeutung. (orig./RHM)

    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.

    The international research project RESIDENS (more efficient energy utilization by means of system technical integration of the private ultimate consumer) investigates the technology of smart metering that is the utilization of intelligent smart meters in private households. The interdisciplinary character of the RESIDENS project becomes visible by different sub-projects examining different formulations of a question from perspectives of different scientific disciplines: First of all, chapter 2 of the contribution under consideration follows up the question, what impact the media coverage on smart metering has on the perception of this technology in the population at large. Chapter 3 reports on the state of the art of the smart metering. Chapter 4 illustrates how a load control of private consumers can be performed by means of the smart meter technology. Chapter 5 reports on the impacts of the smart metering on the procurement of energy in the liberalised energy market. Chapter 6 investigates the smart metering from the customer's point of view. Concretely, the user-friendliness of an internet portal is evaluated by which the customers may follow up their consumption of electricity by means of an intelligent smart meter continuously. Chapter 7 illustrates legal aspects of smart metering from the perspective of the customer, electricity suppliers and distribution system operators. Chapter 8 presents the conception and implementation of an online gaming operation for the promotion of competency of private power customers: In line with this game, the participants may learn to handle smart metering and flexible electricity tariffs in an entertaining manner. Finally, chapter 9 reports on an expert interview in which the smart metering technology is evaluated by public utilities being involved in this project.

    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.)

    There are two different types of fuel cells for small-scale applications, li.e. polymer electrolyte membrane fuel cells (PEMFC) and high-termperature fuel cells with ceramic solid electrolytes (SOFC). Both types of fuel cells have different advantages and shortcomings. One of the main problems, however, is the fact that research is still going on and that commercial fuel cell systems for space HVAC applications are still not available. (orig.) [Deutsch] Nach dem heutigen Stand werden zwei unterschiedliche Brennstoffzellen-Typen zum Einsatz in Kleinanlagen entwickelt. Neben der zu Klasse der Niedertemperatur-Brennstoffzellen gehoerenden Polymer-Elektrolyt-Membran-Brennstoffzelle (PEMFC) ist dies die Hochtemperatur-Brennstoffzelle auf der Basis eines keramischen Festelektrolyten (SOFC). Beide Brennstoffzellen-Typen haben unterschiedliche Vor- und Nachteile fuer den Einsatz zur Gebaeudeversorgung. Eines der Hauptprobleme, das allerdings beide Zellentypen gemeinsam haben, besteht in der noch nicht abgeschlossenen Entwicklung und - daraus resultierend - der fehlenden kommerziellen Verfuegbarkeit im Bereich der Gebaeudeversorgung.

    The geological conditions in Germany allow maximum temperatures between 160 to 170 C free well head taking techno-economic constraint into consideration. This makes an electricity production for purely technical reasons possible, but only with low efficiencies due to physical constraints. That's why it assault big amounts of waste heat. For example, the existing geothermal power plants in Germany provide in average 18% of electricity and 82% of heat. This heat is use so far only to a very small degree. Even is a district heating system is operated to supply private households, this heat is used with less than 2.500 h per year. That's why the still hot thermal water is press back into the underground without any further utilization. For these reasons to achieve a technical and economic optimization it should be the aim to find different reasonable options to use this waste heat. One possibility is the coupling with a drying process at the location of the geothermal plant. Such options will be analyzed from a technical and economic point of view and some conclusions will be drawn. (orig.)

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

    A possibility to supply energy from gaseous biomass is the generation of biogas and bio-SNG, respectively, with a subsequent conditioning to bio methane which can be fed in into the natural gas distribution system. Under this aspect, the author of the book under consideration reports on how the conventionally used natural gas can be substituted by the biogas. It is investigated whether the transformation of biogas or bio-SNG to bio methane is worthwhile under economic and ecologic aspects. It is also investigated to what extend natural gas can be exchanged by bio methane under consideration of the technical and legal frameworks.

    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 German government has decided for the nuclear phase out, but a decision on a strategy for the management of the highly radioactive waste is not defined yet. Partitioning and Transmutation (P and T) could be considered as a technological option in the process of management of highly radioactive waste management, therefore a wide study has been conducted. In this group objectives for P and T and the boundary conditions of the phase out have been discussed. The fulfillment of the given objectives is analyzed using simulations of molten salt reactors with fast neutron spectrum. It is shown that the efficient transmutation of all existing transuranium isotopes would be possible in 3 to 4 reactors in a time frame of 45 to 60 years. Further on a detailed balance of different isotopic inventories is given to allow a deeper understanding of the processes during transmutation.

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

    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.

    Often, legal regulations governing the electricity and gas industries are thought prematurely to apply to district heating as well. The author shows that the technical and economic boundary conditions of district heating are quite different in many respects. He starts by explaining the concept of district heating and analyzing its economic boundary conditions. The next instalment will follow in the next issue of EuroHeat and Power and will focus on the heat market and its legal boundary conditions.

    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.)

    The statement is not new, but is repeatedly a tropical subject. Further technological developments permit advances, e.g. in medicine, production, communication or energy supply. This is particularly clear from the example of natural gas. As with other fossil energy sources the resources are also limited in this case, which is all the more painful, because natural gas is an ideal product in the creation of the energy revolution. In this situation it is highly appropriate that with a special method it is possible to exploit deposits, which could not be developed economically until a few decades ago. (orig.)

    Historical analyses of what metabolism has been conceived of, how concepts of metabolism were related to disciplines such as nineteenth-century nutritional physiology or twentieth-century biochemistry, and how their genealogies relate to the current developments may be helpful to understand the various, at times polemic, ways in which the boundaries between metabolism and heredity have been re-drawn. Against this background, a small number of scholars gathered in Berlin for a workshop that equally aimed at bringing new stories to the fore, and at considering seemingly known ones in a new light. Some aspects of the discussions are summarized in this paper.

    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.

    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.

  10. A comparison of moment magnitude estimates for the European-Mediterranean and Italian regions

    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

    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.

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

    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.

    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.)

    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.

    From this study, it can be concluded that addition of protein of animal origin to a layer diet will not guarantee for a reduction in feather pecking behavior and an improvement of gut health. Despite this, feather pecking behavior and percentage of wet litter area were reduced in two (Daka-40 and Sonac-50) of four treatments with protein of animal origin.

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

    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.

    Energy Technology Data Exchange (ETDEWEB)

    Wegener, Jens-Karl

    2006-12-15

    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.)

    From June 1991 to 9/92 a total of 28 patients suffering from peripheral (n=20) or centrally (n=8) located soft tissue sarcomas were treated. Tumor resection with negative margins was performed in 20 patients, positive margins remained in 5 patients, and gross macroscopic residual disease in 3 patients. Combined intraoperative and external beam radiotherapy was applied in 22 patients, using IORT doses of 10-20 Gy and an external beam dose of 26-50 Gy. Three patients were irradiated intraoperatively twice with a time interval of 24 h. After a median follow-up of 9.9 months, 20 patients are disease free. Two patients died 4 and 5 months after the end of the therapy with rapidly progressive distant metastases. So far, there have been no IORT infield failures. Mild sensory neuropathy occurred in 1 patient 7 months after treatment. Overall only mild and reversible postoperative and posttherapeutic complications were seen. Based on the retrospective analysis of the target volumes chosen during this working period, a set of horse-shoe-shaped cones was designed, which permitted circular and longitudinal target volumes with a homogeneous dose to be delivered as well. With this dedicated IORT facility simple and safe application of a high boost dose is possible. Further, a clear definition of the target volume, followed by an exact verification and at least integration of this target volume in a three-dimensional treatment plan, is necessary. (orig./Mg)

    Desk research (analysis of the production figures of concrete) and field research (personal discussions with producers and merchants) are carried out to investigate whether the application of fly ash in the production of concrete is feasible. The introduction of fly ash depends on the properties of the final product and of the properties during the process of curing, and these depend on a large number of factors such as cement/sand ratio, quality of cement, specifications of the final product. Products such as paving stones, tiles and blocks are favourable for the application of fly ash in concrete. Building elements, pipes and floor elements are not. Market structure in The Netherlands is outlined and mapped, and the present use of fly ash in the concrete industry is discussed. (In Dutch)

    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.)

    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.

    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).

    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. (orig./UA) [Deutsch] Im vorliegenden 1. 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. Eine nach 21 verschiedenen Nutzungsarten gegliederte Investitionsverteilung wird daran anschliessend zusammengefasst und fuer die Verwendung im Rahmen einer Input-Output-Analyse umgerechnet. Nach der Bestimmung der fuer die Quantifizierung der Beschaeftigungswirkungen notwendigen Berechnungsmatrizen koennen schliesslich die fuer den bundesdeutschen Arbeitsmarkt zu erwartenden Bruttobeschaeftigungseffekte in erster Naeherung ermittelt werden, wobei sektorielle Produktivitaetsaenderungen bis zum Zeitpunkt der Investitionen beruecksichtigt werden. Es ergeben sich insgesamt rund 700.000 neue Arbeitsplaetze, von denen etwa 27% auf die Erhoehung der verfuegbaren Einkommen bzw. den damit verbundenen Anstieg des privaten Konsums zurueckzufuehren sind.

    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.

    The standby consumption of electrical households and office appliances continues to be significant world-wide since the number of products with standby componen ts is constantly increasing. For Germany, a recent assessment of the Fraunhofer ISI (Cremer et al. 2003) for 2001 arrived at an electricity demand of almost 15 TWh for household and office appliances in standby mode. i.e. in standby and off -mode. This represents almost 40% of the total consumption of these appliances and around 3% of the total electricity demand of the final energy sectors in Ge rmany. The standby share in electricity demand is over 80 or even 90% for numer ous appliances. The Federal Environmental Agency calculated that every year stan dby losses in German households and offices are responsible for wasted electrici ty amounting to 3.5 billion Euro (UBA 2004). For the OECD countries, field studi es show that between 3 and 13% of the electricity consumption of households can be ascribed to standby losses (IEA 2001). Without energy policy measures on bot h national and international levels, there is a great risk that a further increa se in standby consumption will occur. Many studies dealing with this subject hav e already been conducted and have shown that low standby consumption is technica lly feasible and usually achievable at a reasonable cost. One possible energy po licy measure to reduce the standby consumption of electrical household and offic e appliances is the introduction of mandatory consumption labelling. In principl e, a high degree of effectiveness is attributed to such regulatory/command-and-c ontrol measures with regard to influencing the energy efficiency of devices. Com pulsory energy labels to identify and, where necessary, to classify electricity consumption produce greater market transparency and offer buyers an additional d ecision criterion. In this way they promote indirectly the development, producti on and supply of energy-efficient products. When combined with comparatively low implementation costs, the cost-benefit ratio is also relatively good compared w ith other measures. Up until now, compulsory energy labels have been used global ly mainly to indicate the consumption in normal operating mode, primarily for la rge electrical domestic appliances and other devices used predominantly in house holds such as water heaters, lighting or air conditioning devices.

    Purpose: To develop a model for simulation the CT morphologic situation of acute pulmonary embolism, to evaluate the accuracy of spiral CT and 3D reconstruction in the detection of artificial emboli and to investigate the influence of the orientation of emboli depending on z-axis orientation. Materials and Methods: Standardized artificial emboli made of wax and of defined size and shape were positioned into the pulmonary arteries of porcine lungs. Castings of the embolized pulmonary arterial trees were made by injection of a special opaque resin. After performance of spiral CT the data sets of the emboli and the pulmonary arteries were post-processed. The 3D segmentations were compared with the anatomic preparation to evaluate the accuracy of spiral CT/3D reconstruction-technique. Technical specimens simulating CT-morphology of acute embolized vessels underwent spiral CT in six different positions with respect to the z-axis. The CT data were reconstructed using a standardized and a contrastadapted method with interactive correction. The 3D emboli were analysed under qualitative aspects, and measurements of their extent were done. Results: In nearly 91%, there was complete agreement between CT and the corresponding findings at the anatomical preparation. Measurements of the 3D reconstructed technical specimens showed discrepancies of shape and size in dependence of the size of the original preparation, orientation and reconstruction technique. Overestimation up to 4 mm and underestimation to 2,2 mm were observed. Measurements of preparations with heights from 14 to 26 mm showed variances of {+-}1,5 mm ({proportional_to}6-11%). Conclusion: The presented models are suitable to simulate CT morphology of acute pulmonary embolism under ex-vivo conditions. Accuracy in the detection of artificial emboli using spiral CT/3D reconstruction is affected by localization, size and orientation of the emboli and the reconstruction technique. (orig.) [German] Ziel: Die Entwicklung von Modellen zur Evaluierung der Spiral-CT und 3D-Rekonstruktion im Nachweis der akuten Lungenembolie (LE) im Ex-vivo-Experiment. Material und Methoden: Standardisierte kuenstliche Emboli definierter Groesse und Geometrie wurden in Schweinelungen eingebracht. Ausguesse der embolisierten Gefaessbaeume mit roentgenkontrastgebendem Kunstharz simulierten das CT-morphologische Vollbild einer Lungenembolie. Die Bilddaten wurden dreidimensional rekonstruiert und die Exaktheit der detektierten Emboluslokalisation durch Korrelation mit dem Originalpraeparat verifiziert. Messungen an technischen Probekoerpern mit eingeschlossenen Emboli definierter Groesse sollten die Messgenauigkeit der kombinierten Spiral-CT-/3D Rekonstruktion in Abhaengigkeit von deren Orientierung zur z-Achse und von der Rekonstruktionstechnik (standardisiert und kontrastadaptiert) aufzeigen. Ergebnisse: Fuer die Detektion und Lokalisation ergab sich eine Uebereinstimmung zwischen Spiral-CT-/3D-Rekonstruktion und dem Originalpraeparat von {proportional_to}91%. Die Messungen der technischen Probekoerper ergaben deutliche Abweichungen in Abhaengigkeit von der Groesse, der Orientierung zur z-Achse und der Rekonstruktionstechnik. Hierbei traten Ueberschaetzungen von bis zu 4 mm, Unterschaetzungen von bis zu 2,2 mm auf. Bei Praeparaten mit Hoehen von 14-26 mm traten Schwankungen in einer Groessenordnung von ca. {+-}1,5 mm ({proportional_to}6-11%) auf. Schlussfolgerung: Die vorgestellten Ex-vivo-Modelle sind zur Simulation der akuten Lungenembolie gut geeignet. Die Genauigkeit der Embolusdetektion wird durch Lokalisation, Groesse, Orientierung und Rekonstruktionstechnik beeinflusst. (orig.)

    There is a large number of different configurations for the combination of a closed cycle gas turbine (CCGT) system and a high-temperature gas-cooled reactor (HTGR). Based on the results of a literature survey an overview of such configurations is presented and a comparison is made for their appropriateness for a small cogeneration system (<60 MWt) to be used in the Netherlands. However, most cycles can only be applied for large-scale energy production or supply heat on a too low temperature level. The direct, recuperated cycle is the only suitable cycle, while that cycle is a simple system and shows an acceptable electric and total efficiency. Calculations were carried out for the co-production of hot water (75-125C and 40-70C) and for steam (10 bar, 220C). By means of a static model and an optimizer the feasible efficiencies for different heat demand are determined. The maximum electric efficiency is 42% for the co-production of hot water and 38% for the co-production of steam. 28 refs.

  12. 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

    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. Damit ist das Internet ist in den letzten Jahren zu einem Kulturraum sui generis avanciert. Zuerst war das Netz vor allem ein vom Sender gesteuertes «Push-Medium», von welchem Informationen rezipiert und heruntergeladen wurden. Nicht jede/r konnte die Funktion des Senders einnehmen. Mit der technischen und sozialen Weiterentwicklung des Internets in den letzten Jahren hin zum so genannten Web 2.0 ist jede/r potenziell ein «Prosumer», also Produzent/in und Konsument/in in einem. Jede/r kann sich dank technisch niedrigschwelliger Softwareangebote potenziell am «Mitmachnetz» beteiligen.

    The present report is the first Technical Report within the research project ''Validation and interpretation of selected models and of the coupling of the system codes ATHLET-CD and COCOSYS'', funded by the German Federal Ministry for Economic Affairs and Energy (BMWi 1501465) and projected at the Reactor Simulation and Safety Group, Chair of Energy Systems and Energy Economics (LEE) at the Ruhr-Universitaet Bochum (RUB). This report deals with the simulation of spray phenomena with the containment code system COCOSYS, which is developed by the German Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) gGmbH. First, post-test calculations of the OECD THAI-2 tests HD-30 and HD-31 are presented. The simulation results are compared to experimental values and thereby assessed. The analysis focuses an the assessment of the simultaneous use of the COCOSYS models IVO (spray model) and FRONT (combustion model) as well as a spray entrainment model developed at RUB regarding the simulation of the phenomena related to the interaction of spray and combustion processes. The simulation results show the necessity to consider the induced turbulences. The simulation of these turbulences is performed by modifying the FRONT input parameters leading to an improvement of the simulation results. The consideration of the entrainment positively influences the simulated flow pattern. Subsequently, the simulation of the entrainment of interacting sprays, as occurring in containment spray systems, is considered. The entrainment of interacting sprays is influenced by droplet collisions and changes of the drag between the droplets and the atmosphere. For the simulation an entrainment factor, which has to be determined externally, is implemented into COCOSYS. Exemplary simulations of the OECD SETH-2 ST3 tests show, that in general the use of entrainment factors enables the calculation of alternated gas distributions.

    The 1st Technical Report was prepared for the research project ''Validation and Interpretation of the ATHLET-CD Model Basis'' funded by the Federal Ministry of Economics and Technology (BMWi1501385) and carried out at the Chair of Energy Systems and Energy Economics at Ruhr-Universitaet Bochum (RUB). This report provides results of the simulation of the Boiling Water Reactor (BWR) experiments CORA-17 and -28 with ATHLET-CD Mod. 2.2A. The system code ATHLET-CD (Analysis of Thermal-hydraulics of Leaks and Transients - Core Degradation) is developed by the German Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) mbH. Code results are compared to measurements in order to assess and to analyze the capabilities of the current code version with regard to the modeling of BWR components. The CORA test series was carried out between the years 1987 and 1993 at the former Kernforschungszentrum Karlsruhe (KfK), now Karlsruhe Institute of Technology (KIT). The investigations provided experimental data regarding the material behavior during the early phase of core degradation in Light Water Reactors (LWR). The tests CORA17 and -28 represented a typical BWR arrangement of the fuel rod bundle and provided insights about the bundle behavior during the quenching process (CORA-17) and regarding the influence of a preoxidized bundle (CORA-28), respectively. The simulation results are analyzed and discussed in terms of the thermal bundle behavior, the zirconium oxidation in steam and the resulting hydrogen generation as well as the material relocation. In particular, the recently extended modeling capabilities of the code in terms of the relocation of BWR components like the absorber blade and the canister wall are assessed. The analysis shows that the code captures the thermal behavior in good agreement in both experiments. An even enhanced reproduction of the test CORA-28 is obtained in comparison to a calculation using the previous code version ATHLET-CD Mod. 2.1A. Hydrogen regeneration calculated for CORA-28 agrees well to the measurements, too. In contrast, the hydrogen production in CORA-17 is underestimated during the quenching phase. Possible reasons for these discrepancies are the underestimation of melt oxidation as well as the oxidation of the absorber material B4C since an adequate modeling of these phenomena is not yet implemented in the code. The simulated material relocation of the fuel rods as well as of the BWR components provides plausible results compared to the experiments.

    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.)

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?

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.

    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.

But what did the first electrically powered devices and machines look like? This, and more, is presented in the ''electric power house'' in Burenwisen Glattfelden in the canton of Zurich. Besides a Kaplan turbine and a sample of the most interesting devices from the past and the present, the focus of the exhibition is on the presentation of the new and old sources of light. The EKZ are pleased to be able to present their ''electric power house'' to the public, providing a broad range of information on energy-related questions and the development of electric power supply.

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.

  10. 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

That Schweitzer, ethicist, theologian and missionary doctor, would show such appreciation for psychoanalysis to which the Zurich pastor had introduced him is not immediately self-evident. This article indicates three points of congruence which may explain the connectivity between Schweitzer's thinking and psychoanalysis.

    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.

  9. Occurrence and assemblage composition of millipedes (Myriapoda, Diplopoda) and terrestrial isopods (Crustacea, Isopoda, Oniscidea) in urban areas of Switzerland.

    Science.gov (United States)

    Vilisics, Ferenc; Bogyó, Dávid; Sattler, Thomas; Moretti, Marco

    2012-01-01

    Terrestrial isopods and millipedes, members of the invertebrate macro-decomposer guild, were collected through pitfall traps in three Swiss cities (Zurich, Lucerne, Lugano). A total of 7,198 individuals of 17 isopod species (7093 ind.), and 10 millipede species (105 ind.) were captured. Besides the Alpine endemic isopod (Trichoniscus alemannicus) and millipede (Cylindroiulus verhoeffi), urban assemblages were mainly composed of widespread, native European and even cosmopolitan species, which are frequent in anthropogenic areas. Overall species richness (isopods and millipedes combined) was similar in Zurich (17 species) and Lucerne (16), while only 13 species were sampled in Lugano. According to the Sørensen index of similarity, species composition of Zurich and Lucerne were more alike, while the one of Lugano was more distinct from the other two cities. This result can be explained by the spatial proximity of Zurich and Lucerne in the north of the Alps compared to Lugano, which is located more distantly and in the south of the Alps. Dominant isopods and millipedes in Zurich and Lucerne were found to be widespread synanthropic species in temperate Europe(Porcellio scaber, Trachelipus rathkii and Ophyiulus pilosus) while the dominant isopod in Lugano (Trachelipus razzautii) is a species with a north-eastern Mediterranean distribution. Our study reveals that the urban millipede and isopod fauna in Swiss cities mainly consists of widespread species, but species of narrower distribution (e.g. Trichoniscus alemannicus, Cylindroiulus verhoeffi) may also find suitable habitats in cities. Despite some signs of biotic homogenization, our study also found compositional differences of millipede and isopod assemblages between northern and southern cities that suggest geographical effects of the regional species pool.

    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.

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.

    Science.gov (United States)

    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.

    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)
