    Soto, Kurt T.; Lilly, Simon J.; Bacon, Roland; Richard, Johan; Conseil, Simon

    2016-02-01

    ZAP (Zurich Atmosphere Purge) provides sky subtraction for integral field spectroscopy; its approach is based on principal component analysis (PCA) developed for the Multi Unit Spectrographic Explorer (MUSE) integral field spectrograph. ZAP employs filtering and data segmentation to enhance the inherent capabilities of PCA for sky subtraction. ZAP reduces sky emission residuals while robustly preserving the flux and line shapes of astronomical sources; this method works in a variety of observational situations from sparse fields with a low density of sources to filled fields in which the target source fills the field of view. With the inclusion of both of these situations the method is generally applicable to many different science cases and should also be useful for other instrumentation.

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.

    When does a course count as 'inverted'? When first faced with a new teaching method, deliberate lectures may want to test it without abandoning the advantages of the established method. Aftes the experiment they have to evaluate additional benefits of the new system for teacher and student. Considering the high workload of lecturers, the help of a third party may be useful to obtain an objective assessment of the results during such a transition. At the University of Applied Sciences 'Hochschule Karlsruhe - Technik und Wirtschaft' in Germany, the SKATING project, funded by the German Federal Ministry of Education and Research (BMBF), offers among other things individual technical and didactic advice. This includes practical help with the development, implementation and testing of innovative lecture formats like the Inverted Classroom Method (also known as flipped class).

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.

Given their relationship, the 1899-1901 Milanese period therefore foreshadowed the Bern period later in 1904. In order to specify the circumstances under which Einstein and Besso got the chance to meet, we will show that their respective families did have interconnected social networks, especially through the electricity sector and the polytechnic engineering Universities of Z\\"urich and Milan. The branch of the Cantoni family, on Michele's mother's side, rather ignored by now, played a crucial role: with Vittorio Cantoni, a renowned electrical engineer ...

  4. Groundwater Temperature in the Limmat Valley Aquifer, Zurich

    Jung, Martin; Rivera, Jaime; Blum, Philipp; Bayer, Peter

    2014-05-01

    In metropolitan areas, the thermal environment is strongly influenced by the effects of urbanization. Urban climate is often described by Urban Heat Islands (UHIs), which are also observed in the shallow subsurface. On the one hand, these temperature anomalies may put sustainable development of urban ground at a risk, but on the other hand, enhanced ground temperatures represent potential energy reservoirs. In this contribution, we focus on the role of hydrogeological conditions for the development subsurface UHIs. As a study case, the Limmat valley forming the city center of Zurich is chosen. The Limmat valley is filled with widely heterogeneous, high-conductive moraine deposits, which host groundwater reaching close to the urban surface. By rigorous temperature-depth metering of the Limmat valley aquifer since the summer of 2013, and by compiling previously measured data, the intensity of Zurich's subsurface UHI is examined. This is done with respect to its special hydrogeology, which is dominated by large-scale infiltrations from the rivers Limmat and Sihl. These generate seasonal temperature variations in the groundwater, with increasing amplitudes in the vicinity of the rivers. The seasonal groundwater temperature changes in the Limmat valley are assessed by complementing measurements from summer and winter. The measurements reveal that groundwater temperatures in Zurich are generally high. Across the Limmat valley, values of beyond 13°C are regionally observed, which is around 4 K higher than annual surface air temperature and around 3 K higher than groundwater temperature in the rural surrounding. Though, urbanization is interpreted as a secondary factor (1-1.5K), as the river infiltration naturally causes high groundwater temperatures in the Limmat valley. In the permeable gravel, the temperature-depth-profiles measured in city wells often show little fluctuation. This may be due to horizontal and vertical mixing of the groundwater, and reflects the

    The Swiss Federal Observatory, which had been founded in 1863 by Rudolf Wolf, was dissolved in connection with the retirement of Max Waldmeier in 1979. The determination of the Zurich sunpot number, which had been a cornerstone activity of the observatory, was then discontinued by ETH Zurich. A smooth transition of the responsibility for the sunspot number from Zurich to Brussels was achieved in 1980, however, through which it was possible to avoid a discontinuity in this important time series. Here we describe the circumstances that led to the termination in Zurich, how Brussels was chosen for the succession, and how the transfer was accomplished.

  6. Transforming Critical Spreadsheets into Web Applications at Zurich Financial

    2010-01-01

    In the insurance industry, spreadsheets have emerged as an invaluable tool to for product pricing, because it is relatively straightforward to create and maintain complex pricing models using Excel. In fact, Excel is often preferred to "hard-code" whenever there are frequent changes to the calculations and business logic which under-pin the pricing of an insurance product. However, problems arise as soon as spreadsheets are deployed to end-users: version control, security of intellectual property, and ensuring correct usage are obvious issues; frequently, integration with other systems is also a requirement. Zurich Financial Services Group is a leading financial services provider; several possible solutions to these problems have been evaluated, and EASA has been selected as the preferred technology. Other spreadsheet collaboration approaches which were considered include Excel Services, and/or custom-built software; however, EASA has provided clear benefits over these strategies.

    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.

Moreover, it is also an important precursor for the formation of secondary aerosols in the form of ammonium salts (ammonium nitrate, ammonium sulfate and ammonium chloride). Previous studies have shown that the vast majority of the ammonia emissions come from the agricultural sector (mostly from livestock farming and fertilizing activities). Other sources such as road transport, waste deposit, energy use and supply can also contribute to the ammonia levels in the urban areas. High concentrations of ammonia are commonly measured at the National Air Pollution Monitoring Network (NABEL) stations in Switzerland. Mobile measurements of ammonia and other pollutants (including BC, CO2, NOx and NR-PM) were conducted in the Wallis region and in Zurich in 2013 to study the spatial distribution of ammonia in Switzerland and identify its major emission sources in these regions. A new heated inlet setup was developed to improve the response time of the ammonia measurements, so that even very local sources could be identified. For both, the Wallis region and Zurich, it was observed that the background values of ammonia have a regional origin, as other pollutants affected by regional changes show similar background trends. These regional background values varied between 5 to 10 ppb during the different days of measurements. Moreover, no big differences were observed in the background values between the city center, the surrounding areas, the highway and the rural areas. The major local source of ammonia observed during these measurements was road transport, producing increases on the NH3 levels up to 4 times the background values. Based on emission factors estimated from tunnel measurements, the traffic was estimated to contribute between 20 -30% of the measured ammonia levels on a daily average in Zurich. Other sources of ammonia that can also contribute significantly to the levels of ammonia

    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.

  19. Albert Einstein at the Z\\"urich Polytechnic: a rare mastery of Maxwell's electromagnetic theory

    Weinstein, Galina

    2012-01-01

    Einstein at the Z\\"urich Polytechnic: he skipped classes, did not attend all the lectures of his Professors, and before going to the examinations he studied instead from the notebooks of his good friend from class, Marcel Grossmann. Einstein the free-thinker did not respect the two major professors in the Polytechnic - Heinrich Friedrich Weber and Jean Pernet - who eventually turned on him. He felt that his beloved science had lost its appeal because Weber's lectures did not include Maxwell's electromagnetic theory. Einstein seldom showed up to Pernet's practical physics course. By his fourth-rightness and his distrust of authority he had alienated his professors, especially Weber, who apparently conceived a particular dislike of him. At the Z\\"urich Polytechnic, Einstein could not easily bring himself to study what did not interest him. Most of his time he spent on his own studying Maxwell's theory and learning at first hand the works of great pioneers in science and philosophy: Boltzmann, Helmholtz, Kirchho...

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

    1986-01-01

    In 1981-83 sublittoral macroinvertebrates were collected by means of SCUBA diving from artificial substrates submerged near the outfalls from eight sewage treatment plants in Lake Zurich. Pollution around the outfall resulted on the one hand in a reduction of pollution intolerant benthic invertebrates, on the other hand in a considerable increase in the relative abundance of pollution tolerant taxa such as leeches, flatworms and crustaceans. Changes in the faunal composition were related to nutrient enrichment and changes in the nature of the substratum due to sedimentation of sewage sludge. Species diversity (Simpson index) showed low values near the outfall from some plants, high values near the outfall from others. Low species diversity did not always mark the sites where greatest pollution has been observed.

  4. Acrylamide in a fried potato dish (rösti) from restaurants in Zurich, Switzerland.

    2016-01-01

    Rösti, a fried potato product, is a large contributor to acrylamide exposure locally in Switzerland. A survey of 55 dishes prepared by 51 restaurants in the city of Zurich showed that the average rösti contained 702 µg/kg acrylamide. By analysing the content of reducing sugars in the potatoes used for frying, it is shown that with simple measures, the exposure to acrylamide could easily be reduced by factor 2 or more, while even improving the culinary experience. Though rösti is a typical dish in the German-speaking areas in Switzerland, the result may be of general interest for fried potato products which are popular in large areas of Central Europe.

    -spot areas and targets at risk (i.e. people, buildings, infrastructures, agriculture, natural and semi-natural systems, cultural heritages) in the considered region by comparing the baseline scenario with alternative scenarios, where different structural and/or non-structural mitigation measures are planned. Risk maps, along with related statistics, provide crucial information about flood risk pattern, and allow the development of relevant and strategic mitigation and prevention measures to minimizing flood risk in urban areas. The present study applied and validated the KULTURisk RRA methodology to the Sihl river case study in Zurich (Switzerland). Through a tuning process of the methodology to the site-specific context and features, flood related risks have been assessed for different receptors lying on the Sihl river valley, which represents a typical case of river flooding in urban area. The total risk maps obtained under a 300 years return period scenario (selected as the reference one) have highlighted that the area is associated with the lower class of risk. Moreover, the relative risk is higher in Zurich city centre, in the few residential areas around the city centre and within the districts that rely just beside to the Sihl river course.

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

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

  12. Simulating the dispersion of NOx and CO2 in the city of Zurich at building resolving scale

    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.

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

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

    Elizabeth B. Brokaw, MS

    2011-05-01

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

    Solar thermochemistry is a novel and very promising route for the production of valuable fuels and chemicals, in which solar energy is collected and concentrated in order to supply the high temperature process heat necessary to drive highly endothermic chemical reactions. Some high temperature endothermic reactions for converting solar energy to chemical fuels have been investigated; the steam-gasification of petroleum derivatives and residues using concentrated solar radiation has been proposed more recently as a viable alternative to solar hydrogen production. This paper reviews this study which is being carried out within collaboration between Petroleos de Venezuela (PDVSA), the Eidgenossische Technische Hochschule (ETH) in Zurich/Switzerland, and the CIEMAT in Spain to study the feasibility of thermochemical falsification form petroleum coke.

    The main objective of the paper is the application of the KULTURisk Regional Risk Assessment (KR-RRA) methodology, presented in the companion paper (Part 1, Ronco et al., 2014), to the Sihl River valley, in Switzerland. Through a tuning process of the methodology to the site-specific context and features, flood related risks have been assessed for different receptors lying on the Sihl River valley including the city of Zurich, which represents a typical case of river flooding in urban area. After characterizing the peculiarities of the specific case study, risk maps have been developed under a 300 years return period scenario (selected as baseline) for six identified relevant targets, exposed to flood risk in the Sihl valley, namely: people, economic activities (including buildings, infrastructures and agriculture), natural and semi-natural systems and cultural heritage. Finally, the total risk index map, which allows to identify and rank areas and hotspots at risk by means of Multi Criteria Decision Analysis tools, has been produced to visualize the spatial pattern of flood risk within the area of study. By means of a tailored participative approach, the total risk maps supplement the consideration of technical experts with the (essential) point of view of the relevant stakeholders for the appraisal of the specific scores and weights related to the receptor-relative risks. The total risk maps obtained for the Sihl River case study are associated with the lower classes of risk. In general, higher relative risks are concentrated in the deeply urbanized area within and around the Zurich city centre and areas that rely just behind to the Sihl River course. Here, forecasted injuries and potential fatalities are mainly due to high population density and high presence of old (vulnerable) people; inundated buildings are mainly classified as continuous and discontinuous urban fabric; flooded roads, pathways and railways, the majority of them referring to the Zurich main

Positive matrix factorization (PMF applied to the organic fraction of PM1 yielded 3 factors: Hydrocarbon-like organic aerosol (HOA related to traffic emissions; organic aerosol from wood burning for domestic heating purposes (WBOA; and oxygenated organic aerosol (OOA, assigned to secondary organic aerosol formed by oxidation of volatile precursors. The spatial variation of the chemical composition of PM1 shows a uniform distribution throughout the city: for primary emissions, road traffic is important along major roads (varying between 7 and 14% of PM1 for different sites within the city, but overall, domestic wood burning is more important for the organic aerosol concentrations in Zurich during winter time (varying between 8–15% of PM1 for different sites within the city. OOA makes up the largest fraction of organic aerosol (44% on average. A new method, based on simultaneous on-road mobile and stationary background measurements and using the ratio of on-road sulfate to stationary sulfate to correct for small-scale dynamic effects, allows for the separation of PM1 emitted or produced locally and the PM1 from the regional background. It could be shown that especially during thermal inversions over the Swiss plateau, regional background concentrations contribute substantially to particulate number concentrations (60% on average as well as to the concentrations of PM1 components (on average 60% for black carbon and HOA, over 97% for WBOA and OOA, and more than 94% for the measured inorganic components in downtown Zurich. The results emphasize, on

    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; pdisorder.

    In a study conducted in Zurich, 1877 apprentices were asked to fill out one of two questionnaires on child custody, court hearings and visiting rights. The results reported in the present paper are based on the responses of the 338 youths (18%) whose parents were divorced. Of the youths included, 46.4% said the child's wishes should be the main criterion in custody decisions; 25.7% were in favor of joint custody and 39.1% opposed to it. The majority of the apprentices thought the child should be heard in court (lowest age recommended: 11 +/- 3.18 years). How often the subjects visited the parent who did not have custody depended on their age at the time of the divorce and whether their parents had remarried.

    Polybrominated diphenyl ethers (PBDEs) have been widely used as flame retardants but they are of concern and are currently being phased-out because of their environmentally hazardous properties and their potential to cause adverse health effects. We analyzed PBDEs in Zurich, Switzerland, and applied a multi-media environmental fate model to back-calculate the rate of PBDE emission to air. PBDE concentrations in ambient air were measured in summer 2010 and winter 2011 in the city center of Zurich. Concentrations were higher in summer (sum PBDEs 118-591 pg m(-3)) than in winter (sum PBDEs 17-151 pg m(-3)), and are on the upper end of concentrations reported in literature for urban sites with no point sources of PBDEs. The emissions derived from our measurements (summer: 53-165 μg capita(-1) d(-1), winter: 25-112 μg capita(-1) d(-1)) and extrapolated to annual emissions for Switzerland (114-406 kg a(-1)) lie in the middle of ranges reported on the basis of substance flow analyses and emission inventories. The difference between summer and winter emissions is small compared to the difference that would be expected from the temperature dependence of PBDE vapor pressure, which would be consistent with emissions occurring to a large extent from flame-proofed materials located indoors under nearly constant temperature conditions and/or emissions to air occurring by suspension of particles containing PBDEs. Compared to previous studies in Switzerland, concentrations and emissions of PBDEs appear to have increased during the last five years with an increasing contribution of decabromodiphenyl ether, despite the addition of PBDEs to national and international regulations.

    The aim of this paper is the application of the KULTURisk regional risk assessment (KR-RRA) methodology, presented in the companion paper (Part 1, Ronco et al., 2014), to the Sihl River basin, in northern Switzerland. Flood-related risks have been assessed for different receptors lying on the Sihl River valley including Zurich, which represents a typical case of river flooding in an urban area, by calibrating the methodology to the site-specific context and features. Risk maps and statistics have been developed using a 300-year return period scenario for six relevant targets exposed to flood risk: people; economic activities: buildings, infrastructure and agriculture; natural and semi-natural systems; and cultural heritage. Finally, the total risk index map has been produced to visualize the spatial pattern of flood risk within the target area and, therefore, to identify and rank areas and hotspots at risk by means of multi-criteria decision analysis (MCDA) tools. Through a tailored participatory approach, risk maps supplement the consideration of technical experts with the (essential) point of view of relevant stakeholders for the appraisal of the specific scores weighting for the different receptor-relative risks. The total risk maps obtained for the Sihl River case study are associated with the lower classes of risk. In general, higher (relative) risk scores are spatially concentrated in the deeply urbanized city centre and areas that lie just above to river course. Here, predicted injuries and potential fatalities are mainly due to high population density and to the presence of vulnerable people; flooded buildings are mainly classified as continuous and discontinuous urban fabric; flooded roads, pathways and railways, most of them in regards to the Zurich central station (Hauptbahnhof) are at high risk of inundation, causing severe indirect damage. Moreover, the risk pattern for agriculture, natural and semi-natural systems and cultural heritage is relatively

    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

    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.) [German] Mit der Verfuegbarkeit leistungsfaehiger Gradientensysteme und schneller k-Raum-Akquisitionstechniken wie der parallelen Bildgebung konnten verschiedene Studien die Machbarkeit der Lungenperfusionsbildgebung in der MRT zeigen.

Hiermit ist es moeglich, die Perfusion der gesamten Lunge mit ausreichend hoher zeitlicher und raeumlicher Aufloesung zu visualisieren. In mehren klinischen Studien konnte bei Patienten mit Lungenembolie, pulmonaler Hypertonie sowie Erkrankungen der Atemwege und des Lungenparenchyms der klinische Nutzen der Lungenperfusions-MRT und die gute Uebereinstimmung mit der Lungenperfusionsszintigraphie nachgewiesen werden.

    Due to the current liberalization process the European gas business is changing rapidly. Many new problems that arise will have to be solved by practical solutions. Especially the German gas business with its very heterogeneous structure is already facing a lot of difficulties, which may also become apparent on a European level with further liberalization progress. An example is the handling of transportation for household customers on the basis of load profiles. The second amendment of the German gas association agreement encompasses technical guidelines for network access, which encompass solutions for some of the arising problems. It becomes evident that the technical guidelines are equivalent to a functional standard for third party access in the German gas market. (orig.) [German] Die europaeische Gaswirtschaft befindet sich, verursacht durch die Liberalisierung der Energiemaerkte, in einer rasanten Umbruchphase.

Ein Beispiel hierfuer ist die Abwicklung von Gastransporten zur Belieferung nicht leistungsgemessener Kunden mittels Lastprofilen. Im Rahmen des zweiten Nachtrags zur VV Gas sind technische Rahmenbedingungen fuer den Netzzugang abgestimmt, die fuer einige dieser Probleme Loesungen darstellen.

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

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

    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 designed to compare the dependence of z=0 galaxy structural and stellar populations diagnostics at constant stellar mass on four measures of the environment: the mass of the host group halos; the projected distance from the center of the halo; the rank of galaxies as central or satellites; and the filamentary LSS density on which the groups reside. The complete ZENS sample contains 1630 galaxies in 141~10^{12.5-14}M_sun 2PIGG groups at z~0.06. We outline the survey motivation and describe novel approaches to quantify the environments of galaxies. We introduce a set of self-consistency checks to define the group centers and to rank galaxies as centrals or satellites, and describe an Nth-nearest-neighbor approach to determine the LSS density field using groups as tracers. We publish the ZENS catalogue of galaxy and group properties, which combines the environmental diagnostics presented here with structural and SED measurements described in subsequent papers.

    Full Text Available Gas and aerosol samples were taken using a wet effluent diffusion denuder/aerosol collector (WEDD/AC coupled to ion chromatography (IC in the city of Zurich, Switzerland from August to September 2002 and in March 2003. Major water soluble inorganic ions; nitrate, sulfate, and nitrite were analyzed online with a time resolution of two hours for the gas and aerosol phase. The fraction of water soluble inorganic anions in PM10 varied from 15% in August to about 38% in March. Seasonal and diurnal variations of nitrate in the gas and aerosol phase were observed with more than 50% of the total nitrate in the gas phase during August and more than 80% of nitrate in the aerosol phase during March exceeding the concentration of sulfate by a factor of 2. Aerosol sulfate, on the other hand, did not show significant variability with season. However, in the gas phase, the SO2 concentration was 6.5 times higher in winter than in summer. Nitrous acid (HONO also showed a diurnal variation in both the gas and aerosol phase with the lowest concentration (0.2–0.6 µg/m3 in the afternoon. The primary pollutants, NO, CO and SO2 mixing ratios were often at their highest between 04:00–10:00 local time due to the build up of fresh vehicle emission under a nocturnal inversion.

    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.

In deze studie wordt specifiek gekeken naar de attitude van verschillende deelsegmenten consumenten inzake energie en de potentieale interesse voor domotica en technische gedragsturing, teneinde energiebesparing te realiseren. Motivaction heeft de studie, die bestaat uit een kwantitatieve en kwalitatieve fase, uitgevoerd. Voor het kwantitatieve deel is gebruik gemaakt van het multiclientonderzoek Socioconsult; gegevens daaruit op het gebied van energie en domotica zijn gekoppeld aan woonbelevingsgroepen. Vervolgens is een aantal domotica concepten voorgelegd aan en getoetst bij individuele consumenten in vier aparte groepsessies.

    The aims of the study were to [1] investigate the performance trends at the 'Zurich 12-h Swim' in Switzerland from 1996 to 2010; and [2] determine the gender difference in peak performance in ultraendurance swimming. In total, 113 male and 53 female swimmers competed in this indoor ultraendurance event while swimming in a heated pool. The number of male participants significantly increased (r² = 0.36, P = 0.04) over time while the participation of females remained unchanged (r² = 0.12, P = 0.26). In the age group swimming performances (P swim performances remained unchanged across the years. Females are able to achieve a similar swim performance in an indoor ultra-endurance swim event of ~40 km. Further studies are needed to investigate whether females are able to achieve similar or even better performances than males in openwater ultra-swimming events such as 'Channel Swimming'.

    Full Text Available Abstract Background The increasing party culture in Zurich presents new challenges, especially regarding the consumption of alcohol and so-called party drugs. Streetwork, the youth advisory service of the city of Zurich, has provided onsite and stationary Drug Checking facilities since 2001 and 2006, respectively. Drug Checking always involves filling out an anonymous questionnaire, which allows the collection of important information about a largely unknown group of users and their consumption patterns. Methods The questionnaires assessed sociodemographic characteristics, consumption patterns, Drug Checking experiences, information behavior and social support. The collected data were statistically analyzed by the Research Institute for Public Health and Addiction (RIPHA. Results The majority of Drug Checking service patrons were male and between 20 and 35 years old. These patrons reported high lifetime prevalences and high consumption frequencies of legal and illegal substances, and they often reported polydrug use. Aside from tobacco and alcohol, the most consumed drugs during typical party nights were ecstasy, amphetamines, cannabis and cocaine. Party drug consumers using Drug Checking services form a heterogeneous group with respect to sociodemographic characteristics and consumption patterns. Users of the onsite Drug Checking facilities were significantly younger, were less experienced with drug testing, and reported more polydrug use than users of the stationary Drug Checking service. Conclusions Drug Checking combined with a consultation appears to be an important harm reduction and prevention measure that reaches a group of consumers with high consumption frequency and polydrug use. Because of the heterogeneity of the target group, different prevention measures must be offered and embedded in an overall local concept.

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. Dies trifft besonders auf das Konzept des Gender Diversity Managements zu. Nicht einbezogen wird außerdem der internationale Forschungsstand zu den neuen Steuerungsformen in Hochschule und Wissenschaft insbesondere im Hinblick auf Prozesse des doing gender.This anthology contains articles about three main topics: first, university-wide concepts for human resource and organizational development regarding the touchstone gender mainstreaming; second, findings of teaching and learning research from a gender-sensitive perspective; and third, gender aspects and gender competence in the everyday life of teaching and learning. 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. This is particularly true for the concept of gender diversity management. Furthermore, the international state of research regarding new forms of regulation in university and science, particularly considering processes of doing gender, is

    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.

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.

    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.

    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.

    The recycling of anthropogenic nutrients derived from the wastewater management systems is often characterized by a complex and uncertain scenario, due not only to the nature of the process but also to the involvement of different stakeholder groups. Over the past 10 years in Switzerland, policies regarding the use of sewage sludge as fertilizer have gradually shifted to a ban on use in agriculture. As a result, alternative methods for the recycling of anthropogenic nutrients may play a relevant role in the near future. This paper uses the analytic hierarchy process (AHP) to examine more closely the nutrient-recycling dilemma by analysing the preferences of a group of German-speaking residents in the city of Zurich for various management scenarios. Nutrient recycling by the use of urine separation toilets and the BioCon treatment process are presented as possible management alternatives in addition to current practice. The study shows that AHP can incorporate the respondents' preferences and multiple objectives when evaluating alternatives with different attributes.

    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.

    In the past, various individual ANP-roles such as Clinical Nurse Specialist and Nurse Practitioner were developed in the USA and in several countries of Northern Europe. In Switzerland, the number of university-educated nurse specialists is still very limited. In order to promote sustainable progress in nursing practice despite of this background, Advanced Nursing Practice teams (ANP-teams) have continuously been established at Kinderspital Zurich for the last eight years. This approach has proven to be an excellent option especially in highly complex situations where targeted and adequate solutions for patients are a major issue. In this article, the structure of the ANP-teams is discussed, with the personnel mix as a key factor. Important supportive elements are a clear definition of tasks as well as an allocation of individual tasks to either clinical or conceptual groups. The ANP teams are highly motivated and goal-oriented, they integrate nurses with various backgrounds of experience or training whereby mutual learning is being encouraged.

    We use the Zurich ENvironmental Study (ZENS) database to investigate the dependence of the merger fraction and merging galaxy properties on environment in a sample of ~1300 group galaxies with $M>10^{9.2}$ $M_{\\odot}$ and 0.05$10^{13.5}$ $M_{\\odot}$, indicating a suppression of merger activity in massive groups. The observed dependence on halo mass is almost independent of galaxy mass and merger stage. At galaxy masses >$10^{10.2}$ $M_{\\odot}$, most mergers are `dry' accretions of quenched satellites onto quenched centrals, leading to a strong increase of the merger fraction with decreasing group-centric distance at these mass scales. Both satellite and central galaxies in these high mass mergers do not differ in color and structural properties from a control sample of non-merging galaxies of equal mass and rank. At galaxy masses < $10^{10.2}$ $M_{\\odot}$ -- where we mostly probe satellite-satellite pairs and mergers between star forming systems -- close pairs (projected distance <10-20 kpc) show instea...

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

    We use the Zurich Environmental Study database to investigate the environmental dependence of the merger fraction Γ and merging galaxy properties in a sample of ∼1300 group galaxies with M > 10{sup 9.2} M {sub ☉} and 0.05 < z < 0.0585. In all galaxy mass bins investigated in our study, we find that Γ decreases by a factor of ∼2-3 in groups with halo masses M {sub HALO} > 10{sup 13.5} M {sub ☉} relative to less massive systems, indicating a suppression of merger activity in large potential wells. In the fiducial case of relaxed groups only, we measure a variation of ΔΓ/Δlog (M {sub HALO}) ∼ –0.07 dex{sup –1}, which is almost independent of galaxy mass and merger stage. At galaxy masses >10{sup 10.2} M {sub ☉}, most mergers are dry accretions of quenched satellites onto quenched centrals, leading to a strong increase of Γ with decreasing group-centric distance at these mass scales. Both satellite and central galaxies in these high-mass mergers do not differ in color and structural properties from a control sample of nonmerging galaxies of equal mass and rank. At galaxy masses of <10{sup 10.2} M {sub ☉} where we mostly probe satellite-satellite pairs and mergers between star-forming systems close pairs (projected distance <10-20 kpc) show instead ∼2 × enhanced (specific) star formation rates and ∼1.5 × larger sizes than similar mass, nonmerging satellites. The increase in both size and star formation rate leads to similar surface star formation densities in the merging and control-sample satellite populations.

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

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

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

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

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

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

    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.

The buildings occupy 10% of the lot, with the rest of the land being used for gardens and play areas. The main building of the school complex is the secondary level school, with capacity for 720 students, 24 classrooms and various rooms for complementary functions such as domestic science, art, work rooms, carpentry, storerooms, and areas for teachers, administration offices and services. The gymnasium has three gymnastic exercise halls, which can be converted into one large hall for sports competitions, a first aid station, a library, workshops, bicycle parking area and complementary services. The building to be used as a kindergarden has playrooms, dressing rooms and bathrooms. The exterior of the building is outstanding as a result of the balance achieved between the bare concrete and the extensive garden áreas and outdoor patios. In the interior, the plastic richness of the structural elements themselves has been used to the maximum advantage —concrete for the walls, columns and beams; ceramic forging; etc.— which are exposed, providing interesting contrasts.Este complejo escolar se compone de tres núcleos claramente diferenciados e independientes, separados entre sí por espacios verdes, públicos o privados.

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

    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.

    Schwebstoffen, die in 20 zumeist Landesinstitutionen z. T. im Zeitraum von 1984-2002 erhoben worden waren, wurde der Versuch unternommen, die Belastungshoehen und Stoffmusterprofile fuer Probenahmelokalitaeten am Rhein und Fluessen in BW, Hess, RP und NRW kenntlich zu machen. Die untersuchten Verbindungen waren die isomeren Di-, Tri- und Tetrachlorbenzene, Penta- und Hexachlorbenzen, Ochtachlorstyren (OCS), Hexachlorbutadien (HCBD) sowie die 6 DIN-(IUPAC-, Ballschmiter)Kongenere der PCB, Substanzen, die zumeist im Sinne von REACH als PBT-, z. T. als vPvB-Stoffe bezeichnet wurden bzw. als ''prioritaer gefaehrliche Stoffe'' (PCBz, HCB, HCBD) eingestuft sind. 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. Die hoeher chlorierten PCB-Kongenere Nr. 138, 153 und 180 (HPCB) erwiesen sich als ausserordentlich persistent. Die Chemiestandorte im Umfeld der Probenahmelokalitaeten Rheinfelden, Grenzach, Lampertheimer Altrhein, Biebesheimer Rhein, Muendung Schwarzbach, Bischofsheim und Griesheim (Main), Hitdorf, Duisburg-Homberg und Huels (Lippe) konnten durch Maxima und spezielle Stoffmusterverteilungen transparent gemacht werden.

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

    Lars Engwall

    2006-01-01

    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.

    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

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.

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

    Directory of Open Access Journals (Sweden)

    Caterina Cardemone

    2016-06-01

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

    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.)

The piles and flooring are of reinforced concrete; the facade is a curtain wall with window banding of Cor-Ten steel and panes of Stopray glass.Con objeto de respetar las Ordenanzas Municipales, el autor ha tratado de integrar la sucesión de plantas retranqueadas en una gran forma piramidal, con todas sus consecuencias como, por ejemplo, las ventanas inclinadas. Dentro de la unidad de conjunto se diferencian las formas simples, mediante franjas horizontales, constituidas alternativamente por antepechos cerrados y bandas de ventanas, subrayándose, además, por el distinto ángulo de inclinación de las superficies y por la diferente configuración externa de las plantas de oficinas y de viviendas, de acuerdo con su función. La organización constructiva se basa en un núcleo vertical central, que alberga las cajas de escalera y de ascensores, y las instalaciones, en torno al cual se agrupan: en las plantas bajas, las oficinas; en las dos plantas superiores, las viviendas, de tipo dúplex; en los áticos, las salas de aire acondicionado, lavaderos, almacenes y calefacción; y por último, en el sótano, garajes y almacenes. Los pilares y forjados son de hormigón armado. La fachada es un muro-cortina, constituido por antepechos de acero Cor-Ten y cristales fijos Stopray.

    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

    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.

    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.

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

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

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

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

    The geothermal heat exchanger transfers heat geothermal heat through the metal wall of the outer pipe to the circulating water. The clean water heats up on its way down and is then pumped up again through the insulated inner riser pipe. The heated water is used for district heating. Drilling started on 26 March 1994, and the system was commissioned on 10 November 1994. Today, it supplies heat and warm water to about 1100 apartments. During its first year of operation the Prenzlau geothermal heat exchanger, which is 2800 m deep, covered more than 20 % of the heat demand of the Prenzlau-West district heating grid. The seasonal performance factor in continuous operation of the 500 kW system is between 8 and 12 % of the weather-dependent peak load, with hourly peaks of more than 700 kW. (orig./AKF) [Deutsch] Die Erdwaermetiefensonde nutzt die Waermeuebertragung vom warmen Erdreich durch die Metallwand des Aussenrohrs zum darin zirkulierenden Wasser.

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.

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.

    We present a fascinating triad relationship between a eukaryotic amoeba and its two bacterial symbionts. The morphological characteristics of the amoeba allowed for a confident assignment to the genus Nuclearia (Opisthokonta, Nucleariidae), but species identification resulted in an ambiguous result. Sequence analysis indicated an affiliation to the species N. thermophila, however, several morphological features contradict the original description. Amoebal isolates were cultured for several years with their preferred food source, the microcystin-producing harmful cyanobacterium Planktothrix rubescens. Symbioses of the amoeba with ecto- and endosymbiotic bacteria were maintained over this period. Several thousand cells of the ectosymbiont are regularly arranged inside a layer of extracellular polymeric substances produced by the amoeba. The ectosymbiont was identified as Paucibacter toxinivorans (Betaproteobacteria), which was originally isolated by enrichment with microcystins. We found indications that our isolated ectosymbiont indeed contributed to toxin-degradation. The endosymbiont (Gammaproteobacteria, 15-20 bacteria per amoeba) is enclosed in symbiosomes inside the host cytoplasm and represents probably an obligate symbiont. We propose the name "Candidatus Endonucleariobacter rarus" for this bacterium that was neither found free-living nor in a symbiotic association. Nucleariidae are uniquely suited model organisms to study the basic principles of symbioses between opisthokonts and prokaryotes.

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

    1983-01-01

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

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

    Germany is an international leader in the development and introduction of renewable energy, i.e. wind and solar (photovoltaic) energy. Both technologies already contribute more than 13 % to national electricity generation. The political support of renewable energies resulted in a variety of different technologies the development of which has not yet been exhausted. The paper describes the state of the art of these technologies as well as selected development tendencies. New technologies can be introduced in a highly developed society only if questions according to their environmental impact are also answered.

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

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

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

    The transformation of the energy system to a de-carbonized energy supply requires a coordinated interaction between the sectors electricity, heat and transport. Thereby, the coupling of the electricity sector with the heating sector is one of the key measures in the transformation. The inclusion of wind and solar energy in the grid can be optimized by exact feed in forecasts, the coupling to the heat sector by means of heat pumps and power-to-heat (heater) allows more flexibilisation of the demand side. This interaction is made possible by intelligent solutions of systems engineering and power management. The development of appropriate incentives, market mechanisms and business models is also required, to make this coupling also economic successful. The contribution present die 80% scenario for the year 2050 created in the research project ''Interaction RES electricity, heat and transport'' and gives examples of future requirements and developments on this topic.

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

  4. The Second Mössbauer Effect

    Science.gov (United States)

    Kienle, Paul

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

  5. Mimicking honeybee eyes with a 280{sup 0} field of view catadioptric imaging system

    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.

  8. The Rules of Ferrous Metallurgy

    Science.gov (United States)

    2010-01-01

    The ways in which the sciences have been delineated and categorized throughout history provide insights into the formation, stabilization, and establishment of scientific systems of knowledge. The Dresdener school’s approach for explaining and categorizing the genesis of the engineering disciplines is still valid, but needs to be complemented by further-reaching methodological and theoretical reflections. Pierre Bourdieu’s theory of social practice is applied to the question of how individual agents succeed in influencing decisively a discipline’s changing object orientation, institutionalisation and self-reproduction. Through the accumulation of social, cultural and economic capital, they succeed in realising their own organisational ideas and scientific programs. Key concepts for the analysis include the struggle for power and resources, monopolies of interpretation, and the degree of autonomy. A case study from the Aachener Technische Hochschule shows that the consolidation of ferrous metallurgy can be conceived as a symbolical struggle between Fritz Wüst, professor for ferrous metallurgy, and the German Iron and Steel Institute, leading to a construction of a system of differences in which scientists accepted being scientists rather than entrepreneurs, and entrepreneurs accepted becoming entrepreneurs and renounced science.

Die Evaluation des zwischen 2003 und 2006 durchgeführten Best-Practice-Projekts gibt praxisorientierte Anregungen zur Implementierung von Gender Mainstreaming, wobei die theoretische Rahmung v. a. durch den Rückgriff auf systemtheoretische Begrifflichkeiten geboten wird. Der Fokus liegt dabei schwerpunktmäßig auf dem Aspekt des Gender Mainstreaming und weniger auf einer differenzierten Sicht auf das Thema Diversity.This evaluation report by Hildegard Macha and her colleagues is a detailed organization sociological analysis of and reflection on the introduction of gender mainstreaming at the University of Augsburg. While the first part of the book mainly presents the basic theoretical premises and their development, the second part evaluates the actual individual measures. The evaluation of the best practice project, conducted between 2003 and 2006, gives practical suggestions for the implementation of gender mainstreaming, while the theoretical framing is offered mainly through the recourse on system theoretical terminology. In doing so, the focus is predominantly on the aspect of gender mainstreaming instead of a differentiated view on the topic of diversity.

    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)

    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.

    2008-03-01

    At Elsau near Winterthur (CH), a 9th century AD grave with a female skeleton was found in 2003. This grave was reopened one to six years after burial. After manipulating the partially decayed skeleton, the grave was filled with a layer of rocks and a claw of a sea eagle as well as the paw of a fox was placed on top. At least from this time onwards, the grave was situated in the annex of a church. Because of this special burial site for the 42 year old woman, who suffered from different severe illnesses, it is thought that she belonged to the upper class. The postmortal changes at the grave are exceptional and even after thorough research, no equivalent burial procedures are known from this area. To investigate the possibility if the woman migrated to the region of Elsau, the oxygen and strontium isotope composition of several teeth and one long bone of her skeleton was analysed. The results indicate a certain but restricted mobility within the northern Alpine foreland and as a result changes of the isotope composition of the food and drinking water during her childhood. Immigration from regions in which similar burial customs to those used for the woman persisted into the 9th century AD can be largely excluded based on the isotope composition of her skeletal remains. The mobility in the pre-Alpine region supports the interpretation that the woman belonged to the upper class, whose properties where widely distributed.

    We present the results of a pilot XMM-$Newton$ and $Chandra$ program aimed at studying the diffuse intragroup medium (DIM) of optically-selected nearby groups from the Zurinch ENvironmental Study (ZENS) catalog. The groups are in a narrow mass range about $10^{13}M_\\odot$, a mass scale at which the interplay between the DIM and the group member galaxies is still largely unprobed. X-ray emission from the DIM is detected in the energy band 0.5--2 keV with flux $\\le 10^{-14}$ erg cm$^{-1}$ s$^{-1}$, which is one order of magnitude fainter than for typical ROSAT groups (RASS). For many groups we set upper limits to the X-ray luminosity, indicating that the detections are likely probing the upper envelope of the X-ray emitting groups. We find evidence for our optically selected groups to be under-luminous with respect to predictions from X-ray scaling relations. X-ray mass determinations are in best agreement with those based on the member galaxies bulge luminosity, followed by their total optical luminosity and v...

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    2016-08-01

    A new algorithm is presented for post-processing of void fraction measurements with wire-mesh sensors, particularly for identifying and reconstructing bubble surfaces in a two-phase flow. This method is a combination of the bubble recognition algorithm presented in Prasser (Nuclear Eng Des 237(15):1608, 2007) and Poisson surface reconstruction algorithm developed in Kazhdan et al. (Poisson surface reconstruction. In: Proceedings of the fourth eurographics symposium on geometry processing 7, 2006). To verify the proposed technique, a comparison was done of the reconstructed individual bubble shapes with those obtained numerically in Sato and Ničeno (Int J Numer Methods Fluids 70(4):441, 2012). Using the difference between reconstructed and referenced bubble shapes, the accuracy of the proposed algorithm was estimated. At the next step, the algorithm was applied to void fraction measurements performed in Ylönen (High-resolution flow structure measurements in a rod bundle (Diss., Eidgenössische Technische Hochschule ETH Zürich, Nr. 20961, 2013) by means of wire-mesh sensors in a rod bundle geometry. The reconstructed bubble shape yields bubble surface area and volume, hence its Sauter diameter d_{32} as well. Sauter diameter is proved to be more suitable for bubbles size characterization compared to volumetric diameter d_{30}, proved capable to capture the bi-disperse bubble size distribution in the flow. The effect of a spacer grid was studied as well: For the given spacer grid and considered flow rates, bubble size frequency distribution is obtained almost at the same position for all cases, approximately at d_{32} = 3.5 mm. This finding can be related to the specific geometry of the spacer grid or the air injection device applied in the experiments, or even to more fundamental properties of the bubble breakup and coagulation processes. In addition, an application of the new algorithm for reconstruction of a large air-water interface in a tube bundle is

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

    This work aims, as a first step, to analyze rainfall variability in Northern Algeria, in particular extreme events, during the period from 1940 to 2010. Analysis of annual rainfall shows that stations in the northwest record a significant decrease in rainfall since the 1970s. Frequencies of rainy days for each percentile (5th, 10th, 25th, 50th, 75th, 90th, 95th, and 99th) and each rainfall interval class (1-5, 5-10, 10-20, 20-50, and ≥50 mm) do not show a significant change in the evolution of daily rainfall. The Tenes station is the only one to show a significant decrease in the frequency of rainy days up to the 75th percentile and for the 10-20-mm interval class. There is no significant change in the temporal evolution of extreme events in the 90th, 95th, and 99th percentiles. The relationships between rainfall variability and general atmospheric circulation indices for interannual and extreme event variability are moderately influenced by the El Niño-Southern Oscillation and Mediterranean Oscillation. Significant correlations are observed between the Southern Oscillation Index and annual rainfall in the northwestern part of the study area, which is likely linked with the decrease in rainfall in this region. Seasonal rainfall in Northern Algeria is affected by the Mediterranean Oscillation and North Atlantic Oscillation in the west. The ENSEMBLES regional climate models (RCMs) are assessed using the bias method to test their ability to reproduce rainfall variability at different time scales. The Centre National de Recherches Météorologiques (CNRM), Czech Hydrometeorological Institute (CHMI), Eidgenössische Technische Hochschule Zürich (ETHZ), and Forschungszentrum Geesthacht (GKSS) models yield the least biased results.

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

    Energy Technology Data Exchange (ETDEWEB)

    1944-01-01

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

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

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

    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 Enhanced Resolution Imager and Spectrograph (ERIS) is the next-generation adaptive optics near-IR imager and spectrograph for the Cassegrain focus of the Very Large Telescope (VLT) Unit Telescope 4, which will soon make full use of the Adaptive Optics Facility (AOF). It is a high-Strehl AO-assisted instrument that will use the Deformable Secondary Mirror (DSM) and the new Laser Guide Star Facility (4LGSF). The project has been approved for construction and has entered its preliminary design phase. ERIS will be constructed in a collaboration including the Max- Planck Institut für Extraterrestrische Physik, the Eidgenössische Technische Hochschule Zürich and the Osservatorio Astrofisico di Arcetri and will offer 1 - 5 μm imaging and 1 - 2.5 μm integral field spectroscopic capabilities with a high Strehl performance. Wavefront sensing can be carried out with an optical high-order NGS Pyramid wavefront sensor, or with a single laser in either an optical low-order NGS mode, or with a near-IR low-order mode sensor. Due to its highly sensitive visible wavefront sensor, and separate near-IR low-order mode, ERIS provides a large sky coverage with its 1' patrol field radius that can even include AO stars embedded in dust-enshrouded environments. As such it will replace, with a much improved single conjugated AO correction, the most scientifically important imaging modes offered by NACO (diffraction limited imaging in the J to M bands, Sparse Aperture Masking and Apodizing Phase Plate (APP) coronagraphy) and the integral field spectroscopy modes of SINFONI, whose instrumental module, SPIFFI, will be upgraded and re-used in ERIS. As part of the SPIFFI upgrade a new higher resolution grating and a science detector replacement are envisaged, as well as PLC driven motors. To accommodate ERIS at the Cassegrain focus, an extension of the telescope back focal length is required, with modifications of the guider arm assembly. In this paper we report on the status of the

    The main project, where this sub project contributed to, has been structured into two modules: module A (funded by the federal ministry of economics, managed by KIT) and module B (funded by the federal ministry of education and research, managed by acatech). Partners in module A were DBE TECHNOLOGY GmbH, the Gesellschaft fuer Anlagen- und Reaktorsicherheit mbH (GRS), the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the Karlsruher Institute of Technology (KIT) and the Rheinisch-Westfaelische Technische Hochschule (RWTH) Aachen, in co-operation with the Forschungszentrum Juelich (FZJ). Modul B has been executed by the Zentrum fuer Interdisziplinaere Risiko- und Innovationsforschung der Universitaet Stuttgart (ZIRIUS). The overall coordination has been carried out by the Deutsche Akademie der Technikwissenschaften (acatech). The social implications have been evaluated in module B based on the analysis of the scientific and technological aspects in module A. Recommendations for communication and actions to be taken for the future positioning of P and T have been developed. In the project part, coordinated by HZDR - status of R and D - an overview on the whole topic P and T is given. The topic is opened by a short description of reactor systems possible for transmutation. In the following the R and D status of separation technologies, safety technology, accelerator technology, liquid metal technology, spallation target development, transmutation fuel and structural material development, as well as waste conditioning is described. The topic is completed by the specifics of transmutation systems, the basic physics and core designs, the reactor physics, the simulation tools and the development of Safety Approaches. Additionally, the status of existing irradiation facilities with fast neutron spectrum is described. Based on the current R and D status, the research and technology gaps in the topics: separation and conditioning, accelerator and spallation target, and reactor

    Model observers (MOs) are of interest in the field of medical imaging to asses image quality. However, before procedures using MOs can be proposed in quality control guidelines for mammography systems, we need to know whether MOs are sensitive to changes in image quality and correlations in background structure. Therefore, as a proof of principle, in this study human and model observer (MO) performance are compared for the detection of calcification like objects using different background structures and image quality levels of unprocessed mammography images. Three different phantoms, homogeneous polymethyl methacrylate, BR3D slabs with swirled patterns (CIRS, Norfolk, USA) and a prototype anthropomorphic breast phantom (Institute of Medical Physics and Radiation Protection, Technische Hochschule Mittelhessen, Germany) were imaged on an Amulet Innovality (FujiFilm, Tokyo, Japan) mammographic X-ray unit. Because the complexities of the structures of these three phantoms were different and not optimized to match the characteristics of real mammographic images, image processing was not applied in this study. Additionally, real mammograms were acquired on the same system. Regions of interest (ROIs) were extracted from each image. In half of the ROIs a 0.25 mm diameter disk was inserted at four different contrast levels to represent a calcification-like object. Each ROI was then modified so four image qualities relevant for mammography were simulated. The signal-present and signal-absent ROIs were evaluated by a non-pre-whitening model observer with eye filter (NPWE) and a channelized Hotelling observer (CHO) using dense-difference of Gaussian channels. The ROIs were also evaluated by human observers in a 2 alternative forced choice experiment. Detectability results for the human and model observer experiments were correlated using a mixed effect regression model. Threshold disk contrasts for human and predicted human observer performance based on the NPWE MO and CHO

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

    A detailed literature review has been carried out on the topic to identify the areas requiring further investigations. Based on this investigations have been carried out to evaluate the influence of dissolved nitrogen in weld metals on their toughness and strain aging behaviour through fracture mechanics as well as conventional impact testing approaches. MMA C-Mn steel weld metals bearing nitrogen between 80 to 210 ppm were investigated under four different post-weld conditions, namely: 1. as welded, 2. stress relieved, 3. artificially strain aged and 4. artificially strain aged and stress relieved. Quantitative metallography and low load microhardness studies of microphases were integral part of these investigations. The results demonstrate the highly detrimental effect of nitrogen on the toughness behaviour of C-Mn steel weld metal particularly under strain aging conditions. This is substantiated through decrease of acicular ferrite with the accompanying increase in primary ferrite and ferrite with second phases in the microstructures. Also, there is a distinctive increase in acicular ferrite microhardness. Post-weld stress relieving heat treatment under these conditions effects only marginal improvement in toughness and shifts the fracture behaviour from brittle to ductile or quasi-ductile only in the case of low nitrogen weld metals. Comparing the results of the CTOD and Charpy tests, it is observed that both methods measure the influence of nitrogen on toughness behaviour in the same trend but the magnitudes of the effect measured are different whereby the fracture mechanics method appears very conservative.

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.

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

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

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

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

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

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

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

    In 2009, important processes have been initiated which impact on the development of renewable energies in a long-term run. Two of these projects are the Desertic Industrial Initiative and the construction of a 2-GW solar power station in the People's Republic of China. The Desertec Industrial Initiative intends to cover 15 % of the european electricity requirement by means of about 400 billion Euro. It is the largest ever proposed project of renewable energy. In order to document the current knowledge and to make it available, the project group 'Renewable Energies' of the engineering insurer in the German Insurance Association has prepared this publication. This publication provides a current overview of the state of the art and the technical potential threat for the conversion of solar energy, wind energy, hydropower, geothermal energy and biomass into usable energy.

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

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

    In December 2000 and January 2001 the current state of knowledge and experience of the combustion of meat and bone meal (MBM) and tallow was compiled and examined. Taken into account the existing regulations and recommendations, this report was written in order to provide guidance on techniques and standards for the thermal mal treatment of these materials. It is supposed to assist both operators of incineration plants and authorities to evaluate the suitability of a process and determine the necessary prerequisites. Lacks of knowledge are identified, and recommendations for gathering further information and experience are given in the report. The preparation of this report involved extensive discussions with representatives of incineration plants, governmental departments and MBM processing plants. The report includes physical and chemical data on MBM and tallow. It compiles the current experience with the combustion of MBM and offers requirements and recommendations. (orig.)

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

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

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

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

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

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

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

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

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

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

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

    2002-01-01

    During the early period of rocket development several pioneers originating from the former Austro-Hungarian empire contributed their ideas to the new field of rocketry. The most well known - regarded as the "father of rocketry" in Western Europe - is Hermann Oberth. The others were Max Valier, Franz von Hoefft, Guido von Pirquet, Hermann Potocnik, Friedrich Schmiedl, Franz Ulinski, Eugen Saenger and others. Franz Ulinski (1890-1974) was born 1890 in Blosdorf, Moravia (now Mljadejow, Czech Republic). After attending schools in Wels, Upper Austria, he started a career in the Austro-Hungarian Army in 1910. During his service he worked beginning 1917 at an airplane engine plant in Fischamend and in 1919/20 at the "Fliegerarsenal" (aircraft arsenal) in Vienna. End of 1920 the army of the remaining republic of Austria had to severely reduce its forces and Ulinski was superannuated without further payment. Since 1917 he was also inscribed at the College for Advanced Technology in Vienna ("Technische Hochschule Wien"), but he never graduated, instead he autodidactically attained the VDI-Engineering-Diploma (VDI = "Verein Deutscher Ingenieure"- Association of German Engineers). During 1921-1924 he worked as a development engineer and later as a design engineer for a car factory. In 1925 he set up and ran his own company (radio sale enterprise) and in 1929 an engineering workshop. From 1938 to 1945 he first served as technical staff and later as a design engineer at the Siebel- Flugzeugwerke (Airplane-Factory) in Halle/Saale, Germany. After the Second World War he was employed as a design engineer at different engineering companies in Austria and he died 1974 in Wels. Ulinski's first contact with the topic of space flight occurred during the time period when he was a member of the Austro- Hungarian Army. Ulinski was one of the first in the german speaking part of Europe to publish an article with his ideas about space flight in 1920 (three years before Herman Oberth

    Günther Bauer Günther Bauer. This special issue of Journal of Physics: Condensed Matter is devoted to Günther Bauer, who celebrated his 65th birthday in September 2007. Günther has had a long career in condensed matter physics, but is known particularly for his studies of high magnetic field transport and optics in semiconductors and, more recently, for the discovery and x-ray analysis of self-organized 3D quantum dot crystals. However, his work is much broader than this, as indicated by the wide selection of topics which are represented in this special issue. Günther began his scientific career in Vienna, became associate Professor at the University of Ulm after habilitation at the Rheinisch-Westfälische Technische Hochschule Aachen, Germany, and then ascended to a full professorship at the Montanuniversität, Leoben, Austria, in 1980. He subsequently moved to the Johannes Kepler Universität, Linz, Austria, in 1990. Apart from his outstanding scientific achievements, Günther is also known for organizing the biannual winterschool on 'New Developments in Solid State Physics' beginning in 1980. Initially, he worked at this task together with Helmut Heinrich (until 2000) and Friedl Kuchar (1984 until now) and subsequently with Wolfgang Jantsch (who followed Helmut Heinrich in 2002). This winterschool was, and remains, very important in identifying new trends in solid state physics, and thus has a number of important proponents in the scientific community. It was at one of the first of these winterschools where the initial reports of the quantum Hall effect were presented, and it has been a meeting place where established experts (including three Nobel laureates) teach, and interact with students and young researchers. It is important to know that Günther's excellent international connections were necessary to maintain the high level of the winterschool over almost 30 years. After the first meeting in 1980 in Mariapfarr, these winterschools were held thirteen

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

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

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

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

  6. IN MEMORIAM: Hermann Anton Haus, 1925 2003

    Science.gov (United States)

    2004-08-01

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

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

    Wedge-shape joints are a revolution in large-diameter pipe connection. Fitting is simplified considerably as compared to conventional cylindrical joints. Reproducible high-quality connections are achieved at only a fraction of the time formerly required. Assembly follows clear and simple rules. Anybody who can assemble a flange will be able to cope with the tightening system of the wedge-shaped joint.

    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.)

    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. Inhalte werden von Einzelnen oder kollaborativ im Netz erstellt und publiziert, (ausgewählt rezipiert und weiterpubliziert. Damit hat sich das neue Netz zu einem «Pull-Medium» weiterentwickelt, das massgeblich von den Beiträgen der Empfänger/innen mitgestaltet wird. Das Internet wird so zu einem wesentlichen Medium der Partizipation. Die These, wonach das Internet immer stärker zu einem partizipativen Medium wird, ist allerdings nicht unumstritten. So wird eingewandt, dass das Pull-Prinzip des Internets sich oft auf private Inhalte bezieht und dass es schwierig ist, in dem unübersichtlichen Netz eine wirksame Gegen

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

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

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

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

    Beyeler, F.

    2003-07-01

    This article discusses heat pump 'contracting solutions' used in the refurbishment of the central heating systems of two housing developments in Zurich and Thun, Switzerland. In these and other projects, the high level of investment needed for the installation of the heat pumps was met by third-party contractors, who install and operate the space heating and domestic hot water systems and sell the heat energy to the tenants. The system serving the 96 'Rietlihof' apartments in Zurich is operated by the public utilities of the City of Zurich, EWZ, the housing development in Thun by the Bernese power utility BKW. The article stresses the importance of professional planning and the correct choice of heat sources. The ecological and economical advantages of heating system refurbishment projects that use heat pumps built, financed and operated by contractors are discussed.

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