    Hahn-Meitner-Institut fuer Kernforschung Berlin (HMI) is one of the twelve large research centers of the Federal Republic of Germany; like the other centers, it has to present a combined research programme and budget (programme budget) every year. In these programme budgets, as in the medium-term financial planning in the federal budget, planning for the current year is combined with a medium-term plan for the three next years. For the year 1981, the budget of HMI includes a total expenditure of about DM 85 million, DM 71.2 million of which are direct R + D expenditures. This R + D programme is carried by 396 of the total staff of 705. Research is done in the following fields (approximate figures): Heavy ion physics DM 23.0 million. Radiation- and photochemistry DM 11.4 million. Solid state research DM 20.9 million. Nuclear chemistry DM 8.9 million. Data processing/electronics DM 7.0 million. (orig./UA) [de

    This paper demonstrates how maglev technology solves the classic problem of integrating two airports in a metropolitan area. So far, this has never been attempted because the mode of transportation that could handle this challenge effectively had not been invented yet. This also means that maglev technology is no longer 'the solution in search of a problem'. (orig.)

    The pollution of air by nitrogen dioxide (NO{sub 2}) in cities is one of the central challenges of air pollution in Germany, in addition to the pollution of particulate matter (PM10). In cooperation with the British non-governmental organization ClientEarth, the German Environmental Aid (DUH) filed a lawsuit in November 2015 for exceeding air quality limits for NO{sub 2}. The cities of Stuttgart, Frankfurt, Duesseldorf, Essen, Gelsenkirchen, Aachen, Cologne and Bonn are affected. Here, citizens are constantly exposed to high air pollution. Because of the excess of the NO{sub 2} limits at all traffic-related measuring stations in Berlin, the DUH initiated legal steps and filed a lawsuit too in June 2016. With the lawsuits, DUH wants to promote the implementation of measures to reduce NO{sub 2} in Germany. [German] Die Belastung der Luft durch Stickstoffdioxid (NO{sub 2}) in Staedten ist neben der Belastung durch Feinstaub (PM10) eine der zentralen Herausforderungen der Luftreinhaltung in Deutschland.

    Full Text Available En 1667, le Grand Électeur Frédéric-Guillaume de Brandebourg publiait un document qui annonçait la fondation d’une cité internationale universitaire de Brandebourg pour les sciences et les arts. Cependant, ce projet ne fut pas réalisé. À cette époque, il existait à Berlin la bibliothèque et le cabinet de raretés du prince électeur. Mais Berlin resta sans université jusqu’au début du xixe siècle. Le fils du Grand Électeur, l’électeur Frédéric III (devenu le roi Frédéric Ier de Prusse en 1701, établit la Société des sciences de Brandebourg en 1700 qui changea de nom à plusieurs reprises, mais qui existe encore aujourd’hui sous le nom d’Académie des sciences de Berlin-Brandebourg. Leibniz, qui en a élaboré les statuts, devint son premier président encouragé par l’épouse de l’Électeur, Sophie-Charlotte. D’autres institutions scientifiques berlinoises ont vu le jour dans le courant du xviiie siècle : l’Observatoire (1709, le Théâtre anatomique (1713, le Collège médico-chirurgical (1724, le Jardin botanique (1744, l’Observatoire chimique (1753.

    At a cost of about DM 600 million, Bewag is constructing a new heating power station in central Berlin which provides heat and power to the Potsdamer Platz buildings, the Red Townhall, Unter den Linden avenue, and the German President`s office. The combined cycle power station has a total capacity of 760 kW. It is one of the biggest, most modern and most efficient examples of its kind in the world. The elctricity supplied covers about 10 percent of the city`s demand, and the heat generated is sufficient for comfortable heating of about 60 000 medium-sized apartments. (orig.) [Deutsch] Auch energetisch ruestet die neue Bundeshauptstadt auf. Fuer rund 600 Mio. DM stellte die Bewag in Berlin-Mitte ein neues Heizkraftwerk hin, das so prominente Kunden wie den Potsdamer Platz, das Rote Rathaus, die Flaniermeile `Unter den Linden` oder das Bundespraesidialamt seit einigen Tagen mit Strom und Waerme versorgt. Die kombinierte Gas- und Dampfturbinenanlage (GuD) zaehlt mit 760 Kilowatt Gesamtleistung zu den modernsten, groessten und effizientesten der Welt. Der erzeugte Strom deckt etwa 10% des derzeitigen Bedarfs der Stadt, und die Waerme genuegt zur komfortablen Temperierung von rund 60 000 Wohnungen mittlerer Groesse. (orig.)

  18. Die Verfassung der Berliner Republik

    Directory of Open Access Journals (Sweden)

    Julian Krüper

    2015-01-01

    Full Text Available Contemporary constitutional history faces a methodological dilemma: Historiography traditionally calls for scientific dissociation, both temporal and individual, from its objects of research. Yet, changes in constitutional normativity are typically of an incremental nature and can best be studied through a close approach of the contemporaries. Given such a dilemma, this essay undertakes to analyze key features of constitutional law and science of the »Berlin Republic«. Its main thesis is that contemporary constitutional history in Germany can be seen as a »farewell to the interim«, which the »Bonn Republic« can be construed to have been. Several leitmotifs can be identified: The concept of constitutional identity gains attention and influences the discourses implicitly and explicitly. Among them are debates about the scope of constitutional rights (human dignity, freedom of speech as well as about the structure of the democratic and federal polity. Simultaneously, social change gives rise to fundamental constitutional questions such as religious pluralism or same-sex marriage. At the same time, the science of German public law, both within the dimensions of constitutional and administrative law, undergoes a profound process of self-ascertainment. This process brings about a renaissance of fundamental research in the fields of constitutionalism and theory of state.

    A central question of today's political debates is: Which means are there for ensuring a long-term and sustainable energy supply? Here, strategies for covering tomorrow's energy supply assign renewable energies a decisive role. In face of constantly rising prices for fossil fuels like carbon, oil and gas or the still open question concerning the removal of atomic waste, these discussions are eminently urgent. In order to confront climatic change, renewable energies are needed, so that also in the future a longterm and sustainable energy supply is secured. Sustainable energy supply is the context for the project Solarsupport, which has been supported by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (FKZ 0327613). The project has been coordinated by the Institute for Environmental Questions (''Unabhaengige Institut fuer Umweltfragen e.V.'' - UFU) and conducted in cooperation with the Institute for Future Studies and Technology Assessment (''Institut fuer Zukunfststudien und Technologiebewertung gGmbH'' - IZT) and the German Society for Solar Energy, Regional Association Berlin-Brandenburg (Deutsche Gesellschaft fuer Sonnenenergie Regionalverband Berlin-Brandenburg e.V. - DGS). Particularly, the project is concerned with the pedagogical use of solar energy at school. Despite the relatively high number of solar plants at schools, only a few use their plants for pedagogical means. The project Solarsupport surveyed schools with solar plants. As the main reason for the insufficient pedagogical use of solar plants the interviewed teachers named the la ck of a pedagogical concept and their colleagues' disinterest, two factors which are able to reinforce one another. Moreover, it became clear that because of their insufficient technical equipment (no displays, no means for evaluating the plants' output, no connection with the school computers and internet) a high number of the

  5. Radiotherapy of benign diseases in Berlin (West)

    International Nuclear Information System (INIS)

    1. In Berlin (West), X-ray therapy was applied during the year 1973 in 18 hospitals and by 33 practicing physicians. The 3rd quarter of the year 1973 was taken as basis for the frequency of therapeutic X-ray application. From a total of 15912 patients, 9432 were X-rayed on account of malignant diseases, 6480 because of benigne diseases. This number definitely surpasses the number of cases treated in Munich by X-ray therapy. In Berlin, this might be connected to the age structure. 2. Utilizing the quotations and calculations put down in the report about the effect of atomic radiation by the Scientific Committee of the United Nations, and the values quoted for gonadal doses in the literature, a total-GSD-value of 0.82 +- 0.2 mrem/a was calculated for hospitals and practicing physicians in Berlin. In spite of higher frequencies, this value is approximately of the same order of magnitude as the values calculated for Munich for the year 1971 by I. and H.P. Schmelz. 3. The total-GSD-value for the population of the Federal Republic of Germany resulting from artificial radiation exposure during 1976 is reported to be approximately 60 mrem. Thus, the GSD-value for the X-ray therapy of benign diseases lies approximately at 1.3% and should be of minor significance for radiation-hygienic reflections. 4. Of primary concern is still the radiation exposure to individual patients. Because of possible secondary effects, X-ray therapy for keloids and hemangiomas in infancy and youth are of particular significance. For this reason, its proportion to GSD is also in Berlin relatively large. (orig.) [de

    The research reactor BER II is sited at the periphery of Berlin in the neighborhood of residential areas. The operational license is limited until December 31, 2019. The reactor is funded by the Federal Government (90%) and the city of Berlin (10%). The stress test has shown that the reactor is not secured against an aircraft crash (airliner or fast flying military jet), meltdown with remarkable radiological consequences to the public would be the consequence. Further hazards result from the radioactive waste transport, explosions and fires. The emergency measures cannot be considered to be sufficient. The city of Berlin would not be able to fulfill the required measures in case of a radiation accident.

    A two-sensitivity pressure sensor was developed at EADS Deutschland GmbH, the former DC, with high resolution at low pressure, good results at high pressure, and an integrated self-test. Functional tests were carried out, and the technological and technical fundamentals for marketable sensors were developed. In a sub-project, a sensor for pressure testing of CO2-filled air conditioners was developed. This application had specific problems, i.e. higher temperatures and pressures (working temperatures of -40 to 190 C centigrade, working pressure of 200 bar, burst pressure of 300 bar), and separation of media without additional separating media. A sensor concept for this application was developed at TU Berlin University. (orig.) [German] Im Rahmen des Teilprojektes 'Druckmessung in elektrohydraulischen 'X by Wire' - Systemen' wurde ein Zwei-Empfindlichkeitsbereichs Drucksensor entwickelt. Die Haupteigenschaften des Sensors sind eine hohe Aufloesung im niedrigen Druckbereich, die Moeglichkeit auch grosse Druecke zu messen und ein eingebauter Selbsttest. Bei der EADS Deutschland GmbH (ehem. DC) wurde sowohl das Konzept als auch die Simulationsmodelle eines Sensors entwickelt, der in der Lage ist Druecke bis 200 bar zu messen und dabei eine hohe Aufloesung im Bereich von 0... 30 bar liefert. Der Funktionsnachweis fuer den Drucksensordemonstrator wurde erbracht und es wurden technologische und technische Grundlagen fuer Sensorsystemloesungen geschaffen, die eine Umsetzung wesentlich beschleunigen und Marktchance der KMUs erhoehen. Im Rahmen des Teilprojektes 'HT-Druckmesszelle fuer Kfz-Klimasysteme' wurde ein Sensor fuer die Druckmessung in CO{sub 2}-befuellten Klimaanlagen entwickelt. Die Hauptanforderungen an einen solchen Sensor sind einerseits der erhoehte Temperatur- und Druckbereich (-40... 190 C Arbeitstemperaturbereich, 200 bar Arbeitsdruck, 300 bar Berstdruck) sowie die ohne zusaetzliche Trennmedien zu erreichende Medientrennung.

  16. Review of Berliner & Biddle "The Manufactured Crisis"

    Directory of Open Access Journals (Sweden)

    Lawrence C. Stedman

    1996-01-01

    Full Text Available In a provocative new book, The Manufactured Crisis, David Berliner and Bruce Biddle make four sweeping claims about U.S. achievement: there never was a test score decline, today's students are "out-achieving their parents substantially" (p. 33, U.S. students "stack up very well" in international assessments (p. 63, and the general education crisis is a right-wing fabrication. As a progressive, I'm sympathetic to their concerns, but as a scholar who specializes in this material, I find their analysis deeply flawed and misleading. They mischaracterize the test score decline data, mishandle the international findings, and fail to acknowledge students' continuing low levels of academic achievement.

  18. Ninth International Conference draws 15000 to Berlin.

    On June 7-11, 1993, 15,000 people attended the Ninth International Conference on AIDS in Berlin, Germany. More than 1000 speakers led presentations, plenary sessions, and workshops on the 4 major conference topics: basic science, clinical science and care, epidemiology and prevention, and psychological and social impact and social response. During the basic science sessions, evidence was presented of extensive virus variation and migration which reinforced the need for a global vaccine. Also, new information about the pathogenesis of HIV and AIDS was presented which may influence new treatment and prevention approaches. A great deal of discussion about early treatment with zidovudine was generated in the clinical sciences sessions, but no breakthroughs were announced in drugs or vaccines. During the sessions on prevention, it was reported that a 4-year program of condom promotion among prostitutes in Thailand resulted in a 75% reduction in cases of sexually transmitted diseases. Behavior change programs among at-risk populations in many countries have been effective, but they have not had a noticeable effect on the AIDS pandemic because a lack of resources has prevented their replication. The newest at-risk group seems to be young people, especially adolescent girls. During this conference, women's issues were discussed more widely than at any previous conference. Female-controlled methods of prevention, especially a vaginal virucide, received a great deal of attention. People with AIDS participated in the conference by delivering fiery opening speeches, by demonstrating publicly near the former Berlin Wall, and by urging scientists to collaborate on finding a cure rather than competing with each other in order to win a Nobel prize. The fact that the media reports from the conference were pessimistic drew criticism from participants who believe that a general feeling of pessimism will lead governments, researchers, and health care workers to adopt an attitude of

    Bank filtration is the natural or anthropogenically induced process of surface water infiltration into an aquifer. It is of particular importance as a method to gain or pre-treat water for drinking water production. The hydrodynamic and hydrochemical processes during bank filtration were investigated at one rural site in the Oderbruch and at two urban sites in Berlin (Germany). Results show that these sites differ substantially with regard to the characteristics of the hyporheic zone (permeable versus clogged), travel times (decades versus months to decades) and shape of the redox zones (horizontal versus vertical redox succession). The hyporheic zone is a key parameter determining the site characteristics. Since the surface water in Berlin contains a proportion of treated sewage, a number of wastewater-bound substances (e. g. pharmaceutical residues) have been detected in the surface water. Most of them were, however, fully or partly removed during bank filtration. The redox conditions are an important key parameter with regard to the elimination (or persistence) of a number of organic trace compounds (e. g. phenazone, sulfamethoxazole, clindamycin), whose elimination depends on the prevailing redox environment.

    The CERN staff have many hidden talents. Who knows, maybe a colleague you see every day is actually a virtuoso violinist, an accomplished sportsman or an internationally renowned collector. Mathilde Fontanet, a translator in the CERN Translation and Minutes Service, is a writer in her spare time. Those who read her first essays in the Graviton no doubt spotted her talent. Following the publication of four short stories, her first novel, 'Rabenstrasse 5', was published in Switzerland in May 2005. Its backdrop is the busy Berlin arts faculty in the early 1980s. Lydia, a student, meets a young woman who leads her into some rather unusual activities. In parallel, two friends, both professors of literature, each record their thoughts and emotions in a diary. The paths of Lydia and the two professors are to cross... The novel will be published in France on 14 October. Mathilde Fontanet will present it in the framework of a forthcoming 'Literature in Focus' event in the CERN Library. Mathilde Fontanet'Rabenstras...

  1. Heart transplantation at the Deutsches Herzzentrum Berlin.

    The Deutsches Herzzentrum Berlin is one of the largest transplant centers in Germany with more than 1700 transplant procedures, more than 170 being procedures in children, in patients from the beginning of life to 71 years of age. Survival rates during the early and intermediate follow-up are lower than in international data; however, long-term survival at 15 years or more is similar. Discrepant survival rates derive mainly from the organ shortage that resulted in the development of a different allocation system in Germany as compared to North America and in the increasing number of patients undergoing the bridge-to-transplant concept to move the patient to transplantability. Thus, the patient at highest risk of death while on the waiting list, who according to the ISHLT registry is also the patient at highest risk of death early post-transplant, is the candidate most likely to undergo transplantation in Germany. Unfortunately, the myth persists of solving the donor organ shortage by increasing the "fairness" of organ allocation. Major goals of our transplant program are: the introduction of non-invasive cellular rejection screening with the intramyocardial electrogram (IMEG) and echocardiography; to characterize microvasculopathy in biopsy as a novel and easily diagnosed marker for poor prognosis; to identify Quilty as a determinant for poor prognosis; to propose classifications for microvasculopathy and epicardial vasculopathy that consider the diffuse character of the disease; and to provide insights into the therapeutic options and potential clinical benefits of novel immunosuppressive strategies.

    Climate, e.g., air temperature and precipitation, differs strongly between urban and peripheral areas, which causes diverse life conditions for trees. In order to compare tree growth, we sampled in total 252 small-leaved lime trees (Tilia cordata Mill) in the city of Berlin along a gradient from the city center to the surroundings. By means of increment cores, we are able to trace back their growth for the last 50 to 100 years. A general growth trend can be shown by comparing recent basal area growth with estimates from extrapolating a growth function that had been fitted with growth data from earlier years. Estimating a linear model, we show that air temperature and precipitation significantly influence tree growth within the last 20 years. Under consideration of housing density, the results reveal that higher air temperature and less precipitation led to higher growth rates in high-dense areas, but not in low-dense areas. In addition, our data reveal a significantly higher variance of the ring width index in areas with medium housing density compared to low housing density, but no temporal trend. Transferring the results to forest stands, climate change is expected to lead to higher tree growth rates.

  4. Dead Center: Berlin, the Postmodern Gothic, and Norman Ohler's Mitte

    Directory of Open Access Journals (Sweden)

    Steffen H. Hantke

    2006-06-01

    Full Text Available Cultural critics often frame present-day Berlin as a space of historical discontinuities, a nexus of modernity and postmodernity that, in its orientation toward the future, represents post-reunification Germany in all its complexity. However, this framing tends to suppress Gothic imagery, of which traces can be found in the critical discourse on the city. Recuperating such Gothic tropes from critical discourse, and then consciously and strategically re-deploying them, can be a valuable strategy for opening up new venues of thinking about the lingering presence of the past, the high cost of modernization, and the uncanny emotional and affective dimensions of urban space. While this project of recuperation has been taken on in some critical analyses of Berlin, most notably among them Brian Ladd's The Ghosts of Berlin (1997, it is the new German literature on Berlin that proceeds more boldly into the terrain of the Gothic. Among this new "Berlin literature," Norman Ohler's critically acclaimed Gothic novel Mitte (2001 stands out as a cogent analysis of the new Berlin and of the problems of inhabiting a decentralized urban space and reconnecting it to authentic historical experience.

  5. Physics in Berlin I: The Historical City Center

    Science.gov (United States)

    Hoffmann, Dieter

    Hans-Jürgen Treder has written that, “During the nearly 60 years that spanned the call of Hermann Helmholtz to become professor of physics in the Berlin University ... in 1871, and Erwin Schrödinger’s call to the chair of theoretical physics [in 1927] ..., the general history of physics was closely connected to the history of physics in Berlin.”1 Besides Helmholtz and Schrödinger, the list of famous physicists who worked in Berlin during those six decades includes Albert Einstein, Max Planck, Max von Laue, Walther Nernst, Gustav Hertz, James Franck, and Lise Meitner, to name but some of them.2 But the heyday of physics in Berlin arose neither by chance nor out of the blue: It resulted from a long historical process that began with the foundation of the Brandenburg Academy of Science in 1700 by Gottfried Wilhelm Leibniz; the present Academy of Science in Berlin is the direct descendent of that society. With the founding of the Academy in the capital of Prussia, science established itself in Berlin as a constituent part of its social life. It was predominantly in the context of mathematical research and the fields of mechanics and astronomy that physics was practiced at first. The names of such renowned scientists as Leonhard Euler, Joseph Louis Lagrange, Johann Heinrich Lambert, and Franz Ulrich Theodosius Aepinus bear witness to the remarkably high level that mathematical and physical research had reached in Berlin as early as the 18th century. There was no other city in Germany at that time where there was such a large and extraordinary community of mathematicians, physicists, and chemists teaching and carrying out research. You will find a reminder of this early period in the history of physics in Berlin at Behrenstrasse 21 (a street parallel to the western part of Unter den Linden), where Leonhard Euler lived during his Berlin period from 1743 to 1766. Of course, this is not Euler’s original house, since large parts of Berlin were totally destroyed by

  8. The role of studies and analysis in the Berlin crisis

    International Nuclear Information System (INIS)

    Schake, K.

    1994-01-01

    The question posed for this conference was whether military exercises, studies and analysis have made an appreciable difference in the policies associated with tactical nuclear forces (TNF) in the North Atlantic Treaty Organization (NATO). Some of the papers leave the impression that studies, analysis and military exercises have very little impact on the strategy, policy decisions and force posture of NATO tactical nuclear forces. The studies and analyses undertaken during the 1961 Berlin crisis suggest a very different conclusion: that studies and analyses, when specific in scope and carrying some sense of immediacy, can be enormously influential. Whether one considers the changes to be positive or negative, the experience of the 1961 Berlin crisis suggests that studies and analyses had a tangible and direct impact both on contingency planning for the Berlin crisis specifically and on discussions of the role of tactical nuclear forces more broadly. The results of these studies and analyses are discussed

    In 2005, the pianist and conductor Daniel Barenboim initiated the Musikkindergarten Berlin as the first kindergarten in which music is not only used as an occasional add-on but as the central education medium for the child every day. The skills of specially trained kindergarten teachers combined with regular visits by professional musicians of the Staatskapelle Berlin (the Berlin State Opera orchestra) form the basis of a new educational concept, in which children experience music in all its different aspects and in its unique capability as a transfer medium into all the other educational areas. In this context, the method, the aim, and the experimental ground is not only education in or with music, but through music. This paper provides information and examples about first-hand experiences over the last six years. © 2012 New York Academy of Sciences.

    The idea that "shock" therapies were introduced by "Nazi-Psychiatry" very early and used radically in a cruel way darkens the image of these therapies until today. A case analysis of patient files of psychiatric hospitals in Berlin is used to recapitulate the introduction of insulin coma, metrazol and electroconvulsive therapy during the National Socialism era. Contrary to the false assumption that these "shock" therapies would have been introduced and preferred by psychiatrists involved with the Nazi regime and "euthanasia", in the case of Berlin these therapies were delayed by them and seldom used.

    2017-07-01

    Full Text Available Since the early days of film Berlin and the film studios in its suburbs was an important site of production. Signature films for film historians such as Metropolis and The Blue Angel were shot at the UFA studios in Babelsberg. Throughout its history Berlin was and is a popular place for media productions with the city functioning as a text, full of meaning that turns into branded value. The article will investigate the complex relationship of historical and societal events and Berlin as a production site and an imaginary landscape respectively cityscape. Based on the analysis of national and international drama series we will argue that the increasing importance of Berlin as production site and location goes hand in hand with an increasing mediated imagination of the city as a cinematic respectively televisual space that is able to represent past events such as the Nazi regime and the cold war and actual events such as organised crime, counter terrorist activities, and an intercultural life in a modern metropolis.

    Berlin originated from the two twin cities Berlin and Cölln, which both were founded at the beginning of the 13th century. However the real date of their foundation as well as the origin of the first settlers is still unknown. On the Berlin site the historic city center is still visible in the Nikolaiviertel, but the medieval origin of Cölln disappeared almost completely. In 2007 a large scale excavation, which comprised an area of about 1700m(2) of the historical center of the St. Peters church, recovers the remains of Cölln's first citizens and span a period of 500 years of medieval population. Here we present the first genetic analysis of a fivefold children's burial from excavations in Berlin. The genetic data unveiled next to ancestry and eye color data also the kinship and the gender of the five individuals. Together with the archeological context the new gained information help to shed more light on the possible reasons for this burial. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    "Berlin Access", a regional R&D project carried out by six companies and Heinrich Hertz Institute, Fraunhofer Society, is geared towards low cost solutions for fibre access network architectures (PON and CWDM-PON), ONU transceivers, and passive fibre components. Close communication with system manufacturers, non-incumbent carriers, and a city services supplier implementing a local FTTH network supports orientation towards market demands. In this paper we report on a new FTTH transceiver based on an all-polymer PLC motherboard. The waveguides exhibit high transmission, strong optical confinement, and large operation temperature range. Low loss passively adjusted fibre/PLC coupling is achieved by employing a waveguide taper. Downstream/upstream wavelength separation is accomplished by a directional coupler, or, alternatively, a thin film filter inserted into the input/output waveguide (the latter approach also allowing for the provisioning of an overlay broadcasting channel). The horizontal-cavity surface-emitting laser diode, the pin-photodiode (equipped with a thin film filter for improved crosstalk suppression), and the monitor diode are all flip-chip surface mounted; the light being coupled via 45° waveguide mirrors. Chip mounting can be done with a commercial fineplacer using semi-active automatic alignment. Micro-strip lines with impedances adapted to both laser and photodiode are fabricated on the basis of the PLC films. The polymer motherboard integration scheme offers compact transceiver optical subassemblies and lends itself favourably to highly automized, low cost manufacturing with high yield. Extended functionalities like loss of light alarm or concepts for colourless CWDM ONUs can be easily realized with this concept.

    Full Text Available The destruction of Berlin in World War II left the city in ruins and divided into sectors. This division gave rise to different strategies and experiments to reconstruct or reinterpret the city, which left their mark in the second half of the 20th century. The reunification of Germany managed to suture the wound caused by the Berlin wall and to complete the reconstruction, with a new strategy added to the previous ones. The recent polemic about the mimetic reconstruction of the Stadtschloss is a sign that the work initiated in the postwar period has not yet been completed. This article addresses the course of the trials and essays carried out in search of the creation of a new identity after the war.

    Acute Respiratory Distress Syndrome (ARDS) is due to many causes. The absence of a universal definition up until now has led to a series of practical problems for a definitive diagnosis. The incidences of ARDS and Acute Lung Injury (ALI) vary widely in the current literature. The American-European Consensus Conference definition has been applied since its publication in 1994 and has helped to improve knowledge about ARDS. However, 18 years later, in 2011, the European Intensive Medicine Society, requested a team of international experts to meet in Berlin to review the ARDS definition. The purpose of the Berlin definition is not to use it as a prognostic tool, but to improve coherence between research and clinical practice.

    In 1991, the city of Berlin started the implementation of the 'monitoring program natural budget'. The aim of this program is the assessment of biological and ecological effects of atmospheric pollution as well as the analysis and evaluation of the functioning of the natural balance in pine forest ecosystems in the city area of Berlin and in the close vicinity. The investigations should make temporal and regional statements possible. Techniques of active and passive monitoring are applied (effect cadastre) as well as extensive investigations in long-term observation areas (at present pine forest systems). The ecosystem itself is in the foreground as a sensitive indicator for an existing atmospheric pollution load. The results should enable forecasts of the development of the related organisms and the ecosystems under the effect of anthropogenic load factors. (orig.) [de

    The Fifth International Conference on Concussion in Sport was held in Berlin in October 2016. A series of 12 questions and subquestions was developed and the expert panel members were required to perform a systematic review to answer each question. Following presentation at the Berlin meeting of the systematic review, poster abstracts and audience discussion, the summary Consensus Statement was produced. Further, a series of tools for the management of sport-related concussion was developed, including the Sport Concussion Assessment Tool Fifth edition (SCAT5), the Child SCAT5, and the Concussion Recognition Tool Fifth edition. This paper elaborates on this process, the outcomes, and explores the implications for neurosurgeons in the management of sport-related concussion.

Die bei der Stromerzeugung anfallende Waermeenergie auf dem fuer Heizzwecke guenstigen Temperaturniveau >100 C dient direkt der Waermeversorgung bzw. dem Antrieb einer Kaeltemaschine/Waermepumpe zur Bereitstellung von Niedertemperatur-Kuehlenergie im Sommer und Niedertemperatur-Waerme im Winter. Da der jeweilige Bedarf an Waerme und Strom oftmals nicht gleichlaufend ist, kommt es zeitweise zu einem Ueberschuss des Waermeangebots auf den MHKW und zu anderen Zeiten wiederum zu einer Deckungsluecke. Ueberschuessige MHKW-Abwaerme wird darum in einem Waermespeicher zur Rueckgewinnung und Nutzung bei Heizbedarf im Winter gespeichert. Dazu wird erstmalig ein etwa 300 m tiefer salzfuehrender Aquifer genutzt. Die MHKW-Abwaerme wird auf einem Temperaturniveau von 60... 70 C in diesen Waermespeicher eingeleitet und auf einem Temperaturniveau von 60... 20 C zurueckgewonnen und genutzt. Ein flacher Aquifer-Kaeltespeicher in einer Tiefe von ca. 60 m dient der Gebaeudekuehlung.

    The law for recycling and waste demands the utilization also for waste of asbestos cement (ac). The procedure of thermal utilization of ac in the flame of a rotary cement kiln was developed and patented by the research institute IBU-tec Weimar, Germany. The ac-material has to be pre-pulverized and grinded to a degree of fineness of R{sub 90}<15%. Considerations of safety engineering lead to the idea of common fine grinding of old oil (oo) and ac. This new procedure was searched in FuE-project in 1998/99 (financial support by BMBF). A mash of ac and oo was generated as a utilization product ready for firing which was injected into the flame of the rotary cement kiln. This particles of ac smelt to spherical shaped particles at a temperature above 1500 C. They were utilized by clinker formation. The material and gas stream leaving the kiln does not contain fibres of asbestos. This was demonstrated in a small equipment burning test. The industrial realization concerning cement plant Ruedersdorf, near Berlin, was searched, technologically described and safety engineeringly and financially assessed by a project study. Process-technical and financial advantages were seen for the dry fine grinding. The wet fine grinding with old oil could be used in cement plants using old oil as fuel. (orig.) [German] Das Kreislaufwirtschafts- und Abfallgesetz (1994) fordert u.a. die stoffliche Verwertung auch fuer Asbestzementabfaelle (AZ). Das vom Institut fuer Baustoff- und Umweltschutz-Technologie Weimar 1995 entwickelte und patentierte Verfahren zur thermischen Verwertung von AZ in der Flamme eines Zementdrehrohrofens erfuellt diese Forderung. Das AZ-Material muss vorzerkleinert und bis zur Rohmehlfeinheit (R{sub 90}<15%) feingemahlen werden. Sicherheitstechnische Ueberlegungen fuehrten zu der Idee, die Feinmahlung zusammen mit Altoel (AOe) zu erproben. Diese Verfahrensvariante wurde im Rahmen eines FuE-Projektes 1998/99 untersucht (finanzielle Foerderung durch das BMBF). Als

    2013-09-01

    Full Text Available I want to focus on two recent debates in Germany from the same inaugural period of Germany’s SPD–Green government, which both have as their focus the contestation of memory in relation to the Holocaust. In both debates the Holocaust serves as a negative myth of origin and a primal phantasmatic scene of guilt and shame around which German national identifications are organised. The first is the Walser–Bubis debate and the second the much more protracted but no less fierce debate about the building of a Holocaust memorial in Berlin, which peaked around the same time. Both debates are important in the German context because they come at the end of a long period of Christian Democratic (CDU rule and at the beginning of a new SPD era in German politics. They are significant, moreover, because they appear to send contradictory messages about German self- understanding to the international community.

    1999-01-01

    After Freud proposed in 1918 the creation of "institutions or out-patient clinics [where] treatment will be free," Max Eitingon, Ernst Simmel, and other progressive psychoanalysts founded the Berlin Poliklinik, a free outpatient clinic. Guided by Weimar Republic principles of "radical functionalism," the Poliklinik and its companion inpatient service, the Schloss Tegel Sanatorium, pioneered treatment and training methodologies still used--and still debated--today. Their funding strategies, statistics, and approaches to clinical problems like length of treatment tell the history of an innovative psychoanalytic institute where men and women were generally treated in equal numbers and patients (ranging in occupational status from unemployed to professional) of all ages were treated free. Franz Alexander, Karl Abraham, Theresa Benedek, Paul Federn, Otto Fenichel, Edith Jacobson, Karen Horney, Erich Fromm, Helene Deutsch, Hanns Sachs, Sándor Radó, Hermine von Hug-Hellmuth, Wilhelm Reich, Annie Reich, and Melanie Klein all worked at the Poliklinik, and from there initiated decades of original clinical theory, practice, and education.

    Schmidt, Erika S

    2010-01-01

    Freud considered Franz Alexander, the first graduate of the Berlin Psychoanalytic Institute and an assistant in the Berlin Polyclinic, to be "one of our strongest hopes for the future." Alexander went on to become the first director of the Chicago Institute for Psychoanalysis in 1932 and modeled some of the Chicago Institute's mission on his Berlin experiences. He was also a researcher in psychosomatic medicine, a prolific writer about psychoanalysis and prominent in psychoanalytic organizations. As he proposed modifications in psychoanalytic technique, he became a controversial figure, especially in the elaboration of his ideas about brief therapy and the corrective emotional experience. This paper puts Alexander's achievements in historical context, draws connections between the Berlin and Chicago Institutes and suggests that, despite his quarrels with traditional psychoanalysis, Alexander's legacy may be in his attitude towards psychoanalysis, characterized by a commitment to scientific study, a willingness to experiment, and a conviction about the role of psychoanalysis within the larger culture.

    Full Text Available Berlin Mitte is one of the most interesting parts of the city, located in the core of Berlin where every corner and stone can tell a story. Mitte, the cultural center of Berlin is also known as the political and economic hub of Berlin. This paper explores the urban and historical image of two important parts of Berlin Mitte district: Alexanderplatz and Friedrichstaße. Friedrichstraße, as the main shopping and business street in this area, was planned with great attention by Prussian authorities, while the area around Alexanderplatz grew up randomly and its streets did not follow any special urban patterns. All potential international investors wanted to come to Friedrichstraße after the fall of the Wall, while Alexanderplatz was not so attractive to them. Many famous architects took part in numerous competitions regarding urban planning reconstructions of the famous Alex throughout the 20th century. These two areas of the Mitte district, Alexanderplatz and Friedrichstaße, are very important for contemporary Berlin and both areas have different problems.

    Terrorist attacks induce various responses in emergency responders. Addressing this range of responses in individual workers is of central interest. To assess the gender- and occupation-specific effects of a terrorist attack, particularly in emergency responders. This was a pilot study. Emergency responders present during the 2016 terrorist attack at Breitscheidplatz in Berlin were asked to participate. Measures for crisis management had been previously implemented. Stress (Patient Health Questionnaire [PHQ]), quality of life (The World Health Organization Quality of Life [WHOQOL-BREF]), post-traumatic stress disorder (PTSD Checklist for DSM-5 [PCL-5]) and current psychological symptoms (Brief Symptom Inventory [BSI]) were assessed. Thirty-seven subjects were included, 11 female and 26 male. The occupational groups included 16 firefighters, six police officers, five psychosocial health care personnel and nine members of aid organizations. Three months after the attack, female workers showed higher scores in stress and paranoid ideation, police officers showed higher scores in hostility and firefighters scored lower quality of life in environment and physical health. The mental health burden identified in this study plays an important role for emergency responders after terrorist attacks. Differences between occupational groups may be attributable to differences in tasks that responders perform during acute incidents. The presence of these differences 3 months after the incident suggests that these are at least medium-term conditions. This study may inform the development of treatments and policies and it thus recommended to develop a multi-level assessment and treatment programme that is gender- and occupation-specific. © The Author(s) 2017.

    Management of mechanical circulatory support in children with congenital heart disease (CHD) is challenging due to physiologic variations and anatomic limitations to device placement. In this study we examine the use of Berlin Heart EXCOR in CHD patients. CHD patients were identified from the EXCOR Pediatric Study data set (2007 to 2010). Mortality and serious adverse events were compared between CHD and non-CHD cohorts, and predictors of poor outcomes in the CHD cohort were identified. CHD was present in 29% (n = 59, 18 with 1-ventricle physiology) of all EXCOR patients (N = 204). Successful bridge (transplant or wean) was less likely in CHD patients compared with non-CHD patients (48% vs 80%; p 1 year) were successfully bridged. Pre-implant congenital heart surgery (CHS) and extracorporeal membrane oxygenation (ECMO) on the same admission occurred in 60% of children ≤1 year of age (83% of neonates, 50% of infants), with 8% survival. Regardless of age, patients who did not have CHS and ECMO had 61% survival. Smaller pump, pre-implant bilirubin >1.2 mg/dl and renal dysfunction were independently associated with mortality. End-organ function at implant reliably predicts adverse outcomes and should be considered when making implant decisions. EXCOR use in neonates and infants with CHD should be approached cautiously. If patients have undergone pre-implant CHS and ECMO, EXCOR support may not provide any survival benefit. EXCOR support in non-infants with CHD is challenging but can be consistently successful with appropriate patient selection. Copyright © 2017 International Society for Heart and Lung Transplantation.

    Integral energy concepts for housing estates require an early cooperation between architects, planners, and specialist engineers on the basis of a holistic planning approach. This is how future-oriented, sustainable concepts evolve which do justice to the multifarious requirements on the integral energy system of a housing estate. The present paper elucidates different approaches to optimising the energy efficiency of buildings such as the implementation of low-energy house concepts, building site and architectural planning, and detailed planning of heat insulation concepts, ventilation and air tightness concepts, and adapted heating systems. The solarisation of development plans has an influence on the arrangement of buildings, which are now planned to give the greatest possible passive and active solar energy gains. The authors also describe solar-assisted district heating systems for housing estates. [Deutsch] Integrale Energiekonzepte fuer Wohnsiedlungen erfordern die fruehe Zusammenarbeit von Architekten, Planern und Fachingenieuren im Rahmen einer ganzheitlichen Planung. So entstehen zukunftsweisende und tragfaehige Konzepte, die den vielschichtigen Anforderungen des Gesamtenergiesystems ``Wohnsiedlung`` gerecht werden. Im Folgenden wird die energetische Optimierung von Gebaeuden wie die Umsetzung von Niedrigenergiehaus-Konzepten, Standort und Gebaeudeplanung sowie Detailplanung in Bezug auf das Waermedaemmkonzept, Lueftungs-/Dichtheitskonzept und auf angepasste Waermeversorgungssysteme erl autert. Die Solarisierung von Bebauungsplaenen beeinflusste Anordnung der Gebaeude hinsichtlich der Nutzung passivsolarer Gewinne sowie des Einsatzes von Systemen der aktiven Solarenergienutzung. Solarunterstuetzte Nahwaermenetze fuer Wohnsiedlungen werden ebenfalls beschrieben.

    Full Text Available This article focuses on an almost forgotten type of ›border crosser‹ in the divided city of Berlin: the members of the American military community. To them (as well as to the members of the French and British forces, the Berlin Wall marked the front line of the Cold War. At the same time, though, they were allowed to cross the border and spend their free time in East Berlin. Especially in the 1970s and 1980s, when the dollar was tumbling, American families took advantage of the favourable exchange rate and crossed the border for cheap shopping, dining and entertainment. Due to Berlin’s status, the GDR government had to tolerate this kind of tourism, but nevertheless tried to prevent any personal contact between Americans and East Germans. The regime could also benefit financially from the Western tourists. This demonstrates the ambivalence of the Honecker era, the concurrence of an increased openness and internal erosion. The study is based on documents from the GDR’s Ministry for State Security, the West Berlin Senate Chancellery and the US Berlin Brigade as well as on contemporary newspaper articles. * * * Der Aufsatz widmet sich einer ungewöhnlichen Gruppe von Berliner Grenzgängern: den vor Ort stationierten US-Soldaten.

Die DDR-Regierung war genötigt, die Grenzgänge zu tolerieren. Von dieser Form des Tourismus konnte sie finanziell profitieren, versuchte konkrete Kontaktaufnahmen aber zu vermeiden.

    2004-05-01

    Noise is part of life in Berlin. The Berlin Sound is often described as Berlin is a loud city, but this sound is also a matter of identification. Just like human beings, metropolitan areas may be identified by their gait. People enjoy living in Berlin but they also claim negative health effects and often permanent annoyance caused by daily environmental noise. For instance 1119714 cars demonstrate the volume of traffic from 6.30-9.00 a.m, and another impressive descriptor of the volume of traffic is the number of 1567600 cars from 4.00-6.30 p.m. In a representative survey of 2000 adults, almost all German (80%) citizens are affected by some level of noise pollution. The predominant source of noise in residential areas is road traffic, which remains a nuisance for over half the population, and a source of serious annoyance for some 18%. Next to road traffic, air traffic is the most important transport-related source of annoyance, followed by rail traffic noise. Results from a qualitative survey in a residential area of Berlin give insights into the different perspectives of the noise perception of the investigated subjects and of important parameters with respect to daily life.

  19. Zweiwegintegration durch zweisprachige Bildung? Ergebnisse aus der Staatlichen Europa-Schule Berlin

    Meier, Gabriela

    2012-06-01

    While there is no simple recipe of how to respond to the multitude of languages present in many European schools, this article presents a promising alternative to monolingual education. The focus is on Staatliche Europa-Schule Berlin (SESB), a two-way immersion (TWI) model that unites children whose mother tongue is German with children whose mother tongue is another locally spoken language in one class and teaches them together in two languages. Thus in this model, offered by 17 primary schools and 13 secondary schools in Berlin, pupils learn in two languages from and with each other. Based on a largely quantitative, quasi-experimental study with 603 students, evidence is provided that there are a number of peace-linguistic benefits that can promote two-way social integration, besides fostering personal and societal multilingualism. This suggests that TWI education as practised in Berlin could serve as an educational model for other multilingual parts of Europe.

  20. Candi(e)d action: biosocialities of Turkish Berliners living with diabetes.

    Science.gov (United States)

    Guell, Cornelia

    2011-09-01

    In this article, I explore Turkish migrants' responses to diabetes in Germany. Anthropological studies on health inequalities tend to theorize "social suffering" as passive experiences; those that analyze active social engagement by patient groups as "biosociality" do so solely in the realm of biotechnologies and suggest that social disadvantage prevent active engagement. This article draws on 12 months of ethnographic fieldwork in Berlin from 2006 to 2007. Although Turkish Berliners seem burdened by diabetes, informal diabetes care, for example through a self-help group, is nonetheless collectively negotiated. Increasing incidence and awareness of diabetes in Berlin's Turkish population and their growing political organization and economic entrepreneurship, against the backdrop of experiences of marginality, gives rise to biosociality unanticipated in previous accounts. Addressing the limitations of previous uses of biosociality, this ethnography suggests that social interaction and belonging that formed around altered biologies, here diabetes, are complex and fragmented.

    Lifetime management, ageing management and integrity testing are part of technical rules and specifications. The contribution focuses on ageing management, for which different technical measures are required depending on the safety relevance of the components and systems involved. The procedure for ensuring adherence to the specified quality is outlined, and the required technical and organisational measures are explained. (orig.) [German] In Leitlinien und Regelwerken sind fuer mechanische Komponenten Anforderungen zur Absicherung des Betriebs waehrend der gesamten Lebensdauer (Lebensdauermanagement), zur Absicherung von Alterungsphaenomenen (Alterungsmanagement) als auch zum Nachweis der Integritaet (Integritaetsnachweis, z.B. mit dem Ziel des Bruchausschlusses) enthalten. Ein wesentliches Element stellt dabei das Alterungsmanagement dar. Je nach sicherheitstechnischer Bedeutung der zu betrachtenden Komponenten und Systeme oder auch aus Gruenden der vorbeugenden Instandhaltung sind unterschiedliche technische Massnahmen erforderlich. Die Vorgehensweise zur Absicherung der im Betrieb geforderten Qualitaet wird aufgezeigt und die dabei erforderlichen technischen und organisatorischen Massnahmen werden erlaeutert. (orig.)

    The following parameters merit examination in determining the viability of process combinations: conceptual and technical soundness, environmental acceptability, energy balance, flexibility, costs, economic risk potential. The present contribution on this subject is not intended to take the place of or cover the scope of single-case studies. In practice, viability studies on process combinations have to deal with concrete plans involving precisely defined material flow balances, emissions, costs etc. The present paper therefore only presents the basic principles of this type of study. [Deutsch] Folgende Randbedingungen fuer sinnvolle Verfahrenskombinationen sind zu untersuchen: - konzeptionelle und technische Stimmigkeit, - Umweltvertraeglichkeit, - energetische Bilanz, - Flexibilitaet, - Kosten, - oekonomisches Risikopotential.

Im Rahmen einer echten Pruefung auf `Sinnhaftigkeit` einer Kombinationsloesung stehen sich ganz konkrete Planungen gegenueber, die wiederum mit definierten Stoffflussbilanzen, Emissionen, Kosten usw. verbunden sind. Im Rahmen dieser Betrachtung koennen nur die Grundzuege einer derartigen Pruefung dargestellt werden. (orig.)

    Directory of Open Access Journals (Sweden)

    Andrew Hurley

    2011-09-01

    Full Text Available Hubertus Siegert’s impressionistic documentary, Berlin Babylon, illuminates the demolition and urban renewal of Berlin during the mid-late 1990s. This was a critical phase in the city’s history, as it prepared, amidst a flurry of excitement and anticipation, to become the united Germany's seat of power. Siegert's film seeks to give pause for thought, but deliberately eschews a “voice of god” voiceover, opting instead for a poetic audiovisual montage. This includes shots of the cityscape (and its lacunae, archival footage documenting the wartime devastation and subsequent dynamiting of buildings, observational cinema of the city’s busy building sites, and of verbal snippets from various architects, developers and politicians––following the film title’s cue, the agents in a rerun of the construction of the Tower of Babel––as well as epigraphs from the Bible and Walter Benjamin, and a prominent soundscape and musical score. As this article will demonstrate, the film’s (mostly sombre soundtrack plays a critical role here, commenting on the footage, and beyond that on the whole project of the new ‘Berlin Republic’ and its attitude to architectural heritage and twentieth century history. Re-figuring the theme of this volume, Berlin Babylon’s music is a form of writing about (collapsing, old architecture and history. And yet, the soundtrack is not as unambiguous as a voiceover might have been, and thereby allows creative space for the audience’s interpretation, a matter that was very important to the film’s director. This article will focus, in particular, on three elements: the use (and treatment of historical recordings in the film; the use of silence; and finally the way in which tracks from the Berlin band Einstürzende Neubauten use music, noise and text to comment on the project of the new Berlin.

    2014-07-01

    Full Text Available The spread and durability of harmful neophytes such as Ambrosia (ragweed will increase due to global warming and ever rising globalization. Therefore, in the past years two Ambrosia spp. have established in Berlin. The “Berlin Action programme against Ambrosia” was started in order to monitor the occurrence of the two species in Berlin and to reduce their populations as far as possible. From 2009 to 2012 on average 1.000 populations per year were discovered. In Berlin two species occur, the annual A. artemisiifolia and the perennial A. psilostachya which release their highly allergenic pollen in late summer. The annual herb, which is mostly introduced with bird seed, is often distributed in small populations with up to 10 plants throughout the city and can be successfully controlled by frequenty repeated measures. More problematic is the control of the perennial species which is found in large quantities with more than 1.000 plants and concentrated in the eastern part of the city. Except for constant mowing no other control measures have been tried. Accordingly, there is a need for taking action and developing a process to minimize and eradicate existing populations (A. psilostachya through cooperation with the city authorities (environment, health, agriculture and engineering.

  15. Limits—Urban Density and Mobility Networks in West Berlin during the Period of Containment

    Directory of Open Access Journals (Sweden)

    Vanessa Miriam Carlow

    2014-10-01

    Full Text Available If space may be conceptualized as a natural resource, much like gas, oil, or minerals, then its production and use can also be thought of as something to be properly managed, taken care of, and not wasted. Limiting the expansion of the footprint of built-up land in urban areas forces this particular resource (space to be used more efficiently—in a sense, compelling it to be more creative and productive. These spatial constraints on urban areas generate different kinds of densification processes within the existing city, propagating densification, and with it new patterns and uses in urban development, as well as novel approaches to mitigating the hazards of dense urban environments. This paper examines the case of how spatial containment in West Berlin during the period of the Berlin Wall (1961–1989 produced such outcomes. West Berlin during this period can be considered a unique case of spatial containment, where a relatively large and vibrant modern city had to work around a clear and indelible limit to its physical expansion. This paper will discuss ways in which the containment influenced patterns of development in West Berlin toward densification and connectivity, focusing on the expansion of its infrastructural networks, and discuss the development of a new building culture around transformation and densification, including hybrid architectures and mitigation devices to deal with difficult sites produced by the densification.

    2014-01-01

    Nazi anti-Semitism had a considerable impact on dermatology during the period 1933 to 1945. Before World War II, dermatology in German-speaking lands was at the forefront of medicine, and about 25% of the dermatologists were Jewish. Many perished during the Holocaust; others emigrated from Germany and played a major role in advancing dermatology in their new homes, especially in the United States. Erich Langer (1891-1957) was almost unique, because he survived the entire period in Berlin. Langer had been chief of dermatology at Berlin-Britz, a large city hospital, before 1933 but was discharged almost immediately after the Nazi takeover because of his Jewish roots. In June 1945 he returned to his old department and resumed charge. He became one of the key figures in rebuilding German dermatology in the immediate postwar years. He served as first chair of dermatology at the new Free University in Berlin, started two journals, and wrote several books. Until recently, very little was known about Erich Langer's mysterious tale of survival and how he evaded Nazi roundups. Fortunately, we have discovered considerable archival material that has allowed us to piece together, for the first time, a detailed account of Langer's courageous and remarkable story as the last Jewish dermatologist inNazi Berlin.

    Wholesome living does not contradict energy saving provided that efficient space HVAC systems and low-emission construction materials are used. In view of the reduced controlled air change in passive buildings, emissions from interior materials and furniture should be taken into account as well. The IUG developed a catalogue of criteria of a 'low-allergy building'. The principles and rules governing the construction of a passive building for people suffering from allegies are presented. [German] Gesundes Wohnen und Energiesparen sind kein Widerspruch. Bei staendiger Zunahme innenraumbedingter Allergien sind insbesonders Anfordernisse an Baumaterialien und Raumluft-technische-Anlagen (RLT) zu stellen. Schon fuer die Planer ist es wichtig emissionsarme Baumaterialien einzusetzen. Aufgrund der kontrolliert reduzierten Luftwechselraten sollten ausserdem Emissionen aus Einrichtungsmaterialien wie Bodenbelaege und Moebel mit in die Beurteilung von Passivhaeusern einbezogen werden. Darueber hinaus koennen konstruktionsbedingte Massnahmen einen Schutz fuer zu Allergien neigenden Menschen bedeuten. Das IUG hat einen Pruef- und Kriterienkatalog fuer ein 'Allergiker-gerechtes Oeko-Haus - AL - LOeKH' entwickelt, mit welchem Gebaeude und Anlagen sowohl auf ihre oekologischen Kriterien als auch auf ihre Eignung fuer Allergiker geplant, geprueft und beurteilt werden und bei positiver Bewertung ein entsprechendes IUG-Label vergeben werden kann. In dem vorliegenden Beitrag sollten die Prinzipien und Regeln zur Errichtung und Einrichtung eines Passivhauses dargestellt werden, die die besonderen Anfordernisse fuer Allergiker (Atopiker) mit einschliessen.

  3. Berlin: Sustainability and Tour Guides in a Partial Dark Tourism Destination

    Directory of Open Access Journals (Sweden)

    Asaf Leshem

    2013-10-01

    Full Text Available When guiding in Berlin about the Holocaust or about the Cold War, tour guides often hear the phrase: “I didn’t come here for that, but I want to see that as well...” Many of Berlin’s 10 Million visitors per year claim to have an attraction towards both the morbid and the lighter side of the city. Following from that popular sentiment it is argued that Berlin can be defined as a Partial Dark Tourism Destination. As such, it is further argued that Berlin is prone to an increase of socio-economic and socio-cultural negative impacts. The premise of the research is that Berlin’s tour guides function as a link between the residents of the city and the visitors. The thesis, then, is that tour guides play a role and can contribute to development of social, cultural and economic urban tourism sustainability. An analysis of tourism impacts and tourists-residents relations is presented, in which the tour guide plays a role in influencing the visitor’s behaviour. I conclude that tour guides have greater influence on social, cultural and economic behaviour of the tourist than previously considered, and therefore a potential to enhance sustainable tourism development in Berlin. The significance of this research is in the way it points out to the roles Berlin tour guides play in facilitation of sustainable tourism development in the city. Furthermore, the research shows the ways in which tour guides contribute to increasing responsible tourist behaviour.

    The knowledge of employees of a company is the basis of all actions and decisions in the company and all existing (core) competences, which flow into products and services. Existing advantages in knowledge can be converted into competitive advantages by forward looking knowledge management. In addition there is an opportunity for increases in efficiency, creativity and quality. Locally different but often comparable boundary conditions, which are associated with similar problems, solutions, decisions and actions, prevail in the individual mines worldwide. Hence, knowledge management in international mining companies or joint ventures can contribute to the availability and use of knowledge relevant to value creation without delay in all company divisions. (orig.) [German] Das Wissen der Beschaeftigten ist die Grundlage aller im Unternehmen getaetigten Handlungen und Entscheidungen und aller (Kern-)Kompetenzen, die in Produkte und Dienstleistungen einfliessen. Durch ein zukunftsorientiertes Wissensmanagement lassen sich vorhandene Wissensvorspruenge in Wettbewerbsvorteile umwandeln. Es bietet zudem die Chance fuer Effizienz-, Kreativitaets- und Qualitaetssteigerungen. Im Bergbau herrschen weltweit in den einzelnen Bergwerken zwar lokal unterschiedliche, aber oftmals doch vergleichbare Rahmenbedingungen vor, die mit aehnlichen Problemen, Loesungen, Entscheidungen und Handlungen verbunden sind. Deshalb kann Wissensmanagement in international agierenden Bergbauunternehmen oder Kooperationen dazu beitragen, dass wertschoepfungsrelevantes Wissen ohne Zeitverzug in allen Unternehmensbereichen zur Verfuegung steht und genutzt wird.

    Between 1955 and 1959, the housing estate at the Schiller park in Berlin-Wedding (Federal Republic in Germany) established in the 1920ies was expanded by four-storey house lines, the so-called Glas-Hoffmann buildings. Since 2008, this ensemble belongs to the Unesco World Heritage. In improving the thermal insulation of the building envelope and the adaptation of the building services to today's standards, therefore the architectural aesthetics of these buildings should not be endangered. The retrofitting was a pilot project of the research project ''Monument and energy - Postwar Modernism''.

    It gave the listeners much cause for thought what Professor Dr. Paul Kleinruer, president of the Rhine-Westphalian Institute of Economy research told on a press symposium in Frankfurt at the end of October. He characterised the German politicians of the last five years as naive with a tendency towards self-castigation, when they promised the world a reduction of 25% (Kohl, Berlin 1995). He asked why the Germans already pushed the brakes now with both feet even though the break distance of hundred years is very long because the collapse is only going to occur after one hundred years.

    2015-06-01

    Full Text Available Two major monuments reached Berlin at the end of the 19th century: the marble reliefs of the Altar of Zeus at Pergamon, and the bronze relief plaques from the audience hall of the royal palace at Benin City. Each series of reliefs was placed into a newly built museum, but the curatorial approaches towards the two monuments greatly differed. This paper explores the many factors affecting the presentation of foreign artworks in Berlin, and the relationship between display methods and the development of the museum as a new institution. The paper contends that while racist beliefs about the “Other” certainly affected museum exhibitions, the development of new academic fields and the evolving understanding of the purpose of the museum were also driving factors in determining display methods.

    The Berlin Energy Recovery Linac Project (BERLinPro) is designed to develop and demonstrate CW linac technology and expertise required to drive next-generation Energy Recovery Linacs. Strongly HOM-damped multicell 1.3 GHz cavities are required for the main linac. The optimization of the cavities presented here is primarily based on the CEBAF 1.5 GHz 5-cell high-current cavity design, including HOM waveguide couplers. The cavity was scaled to 1.3 GHz and extended to 7 cells. Modifications to the end group design have also been studied. An effort was also made to reduce the ratio Epk/Eacc while still permitting HOMs to propagate.

    In 2009 Carl Zeiss stopped the manufacture of precision gratings. All users of their gratings were very concerned about this decision, since they all need precision gratings for their experiments. One of the institutes of the HZB, the Institute for Nanometer Optics and Technology (INT), has extensive experience in micro fabrication (technology group). In spring 2010, HZB decided to take over the old C. Zeiss grating fabrication and build up its own technology center for grating fabrication. In March 2010, the INT applied to the Senate of Berlin for funding for our project from the European Regional Development Fund (ERDF). In October 2010, HZB received an approval of its application from the Senate of Berlin (contract No 20072013 2/43). Using this governmental support, HZB will install all necessary equipment and processes to fulfill these demands until end of 2013.

    Berlin Heart Inc. EXCOR is an extracorporeal pneumatically pulsatile ventricular assist device approved for use in pediatric age group since 2011 in the United States. It is a well-established life-saving therapy for the bridge to heart transplant or to provide circulatory support in a transplanted patient. The most commonly reported problem was "membrane defect" in a postmarketing major device reporting. In general, the filling and emptying of the pump can be easily visualized, but the interobserver variability exist. In this first novel report, we used the iPhone slow motion video to quantify and compare the differences in filling and emptying that positively impacted the management of the Berlin Heart. This is an initial exploratory concept that will need further studies to validate this bedside tool.

    Full Text Available One of the antique libraries most representative of the second half of the 19th century was that of Leo Liepmannssohn, with branches in Paris and Berlin. Its importance grew over time due to its auctions of many manuscripts by J. S. Bach, Handel, Mozart, Beethoven and other composers, a fact that explains how the author came across it during his investigation into the referred manuscripts. The object of this investigation is a collection of more than 300 folders that can be consulted in the Music Department in the Staatsbibliothek Preußischer Kulturbesitz in Berlin. The folders contain the annual catalogues from the antique library of Liepmannssohn (Berlin comprising the years 1866 to 1923. Each catalogue consists of a list of all the sales from the corresponding year in alphabetical order and contains, besides manuscripts, literature, musical treatises and the portraits of several composers. There are many Spanish manuscripts included in these catalogues whose distribution was so important that in 1900 Liepmannssohn published an exclusive catalogue for Spanish and Portuguese manuscripts, 291 of which the librarian had sold during that year. During the celebration of those auctions many documents, musical treatises and manuscripts, both known and unknown, were brought to light. The investigation earned out contributes to our knowledge about the works of different Spanish composers from the 16th to the 19th centuries and their distribution abroad, especially in Berlin.

Developed by the German writer Annett Gröschner, they have been used to reexamine the history of the city – only dimly reflected in the present urban landscape. Her perspective emphasizes the distinctive spatial and architectural organization of the city, particularly after the fall of the Berlin Wall. In order to harness her dialec-tical composition of the spacing of-the-past, Gröschner uses the map of various routes on the Berlin public transport network, some inner-city artefacts set along those lines, and also the city map with its constant modifications to create appropriate landmarks through which she [re]constructs Berlin's past-present.

  5. Conserving water and preserving infrastructures between dictatorship and democracy in Berlin

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available This paper sheds a long-term perspective on the politics of water infrastructure in 20th century Berlin, focusing on how water conservation became enrolled in the political agendas of very diverse regimes, from the Weimar Republic to the present day. The paper poses the following three questions: firstly, in what socio-technical and political contexts have strategies of water conservation emerged (and disappeared in Berlin? Secondly, what meanings have been attributed to these strategies and how were they politically appropriated? Thirdly, what continuities and changes to water-saving strategies can be traced across Berlin’s turbulent 20th century history? These questions are addressed with an empirical analysis of four periods of Berlin’s water infrastructure history: a an era of expansion (1920-1935 about harnessing (regional water for (urban prosperity, b an era of national autarky (1936-1945 about enrolling urban water in the Nazi cause, c an era of division (1948-1989 about reordering truncated water flows in divided West and East Berlin, and d an era of reunification (1990-present in which expansionism has confronted environmentalism, giving rise to contestation over the desirability of water conservation. This empirical analysis is framed conceptually in terms of a dialogue between notions of obdurate socio-technical systems and dynamic socio-material assemblages.

    1996-05-01

    The ATM-based Metropolitan Area Network (MAN) of Berlin connects two university hospitals (Benjamin Franklin University Hospital and Charite) with the computer resources of the Technical University of Berlin (TUB). Distributed new medical services have been implemented and will be evaluated within the highspeed MAN of Berlin. The network with its data transmission rates of up to 155 Mbit/s renders these medical services externally available to practicing physicians. Resource and application sharing is demonstrated by the use of two software systems. The first software system is an interactive 3D reconstruction tool (3D- Medbild), based on a client-server mechanism. This structure allows the use of high- performance computers at the TUB from the low-level workstations in the hospitals. A second software system, RAMSES, utilizes a tissue database of Magnetic Resonance Images. For the remote control of the software, the developed applications use standards such as DICOM 3.0 and features of the World Wide Web. Data security concepts are being tested and integrated for the needs of the sensitive medical data. The highspeed network is the necessary prerequisite for the clinical evaluation of data in a joint teleconference. The transmission of digitized real-time sequences such as video and ultrasound and the interactive manipulation of data are made possible by Multi Media tools.

    Full Text Available One of the greatest battles of the Great Patriotic and also the World War II took place on the outskirts of the capital of Nazi Germany on April 16, 1945. Three magor fronts - 1st Belorussian, 2nd Byelorussian, 1st Ukrainian - and four tank armies were involved. They were not used as highly mobile groups to enter Berlin from the north and north-west, they were sent first to break powerful enemy defenses, and then to wage battles on the streets. The Supreme Command and the commanders of the 1st Byelorussian and 1st Ukrainian fronts understood the inevitability of heavy losses in tanks and troops, but deliberately took this step. The aim was not only a speedy capture of the German capital and the end of the war, but also to be ahead of allies on their way to Berlin. The article deals with the planning and preparation for the Berlin Strategic Offensive Operation, the use of 2nd Guards Tank Army, who played along with other tank divisions a magor role in the success of this operation.

Due to their resulting precarious economicsituation, a large number of these migrants became engaged in small businessand petty trade. Some of them, women in particular, have become successfulentrepreneurs and wholesalers in recently built bazaars in the eastern parts ofBerlin. Most interestingly, parts of these urban spaces, former industrial areason the periphery of Germany’s capital, have been transformed into religiousplaces. This article explores the formation of female Vietnamese Buddhistnetworks on the grounds of Asian wholesale markets. It argues that transnationalmobilities in a post-socialist setting encourage border-crossing religious activities,linking people and places to various former socialist countries as well as to theSocialist Republic of Vietnam. Further, by considering political tensions betweenVietnamese in the eastern and western part of Berlin, this contribution illustratesthe negotiation of political sensitivities among diasporic Vietnamese in reunitedGermany. Based on ethnographic fieldwork among female lay Buddhists, itfocuses on entrepreneurship and investigates the relationship between business,migration and religious practices.

  10. Berlin, Maryland - How One Small City is Using Science to Change its World

    Allen, L.; Silbergeld, E.

    2016-12-01

    Small cities are uniquely challenged to mitigate environmental issues in their communities because they usually lack the financial resources and technical expertise to address them. The Town of Berlin, population 4,500, recently purchased approximately 60 acres of private property located at 9943 Old Ocean City Boulevard. The property was previously owned by Tyson Chicken, Inc. and contains a chicken processing plant which has not been in use for over 10 years. Historically the plant emitted significant odors which limited the Town's ability to diversify its economic base. The plant closure provided an opportunity to convert the property to another use, but the downturn in the economy delayed that change. The Town intends to establish recreation oriented uses on the property with the following goals in mind: Create a common ground for the people of Berlin that will unite various neighborhoods. Create synergy between ecological sustainability and community resilience Upgrade the ponds on the property to make them the design focal point Through the Thriving Earth Exchange, the Town of Berlin connected with Dr. Ellen Silbergeld to resolve the question of how to remediate the ponds. Dr. Silbergeld is trained as an environmental engineer and public health researcher, with substantial experience in environmental issues in the poultry industry. This case study will show how one small city is working with a volunteer scientist to convert a blighted piece of property into a multi-use public space for the benefit of its residents and guests.

    It has been confirmed by practical project experience that integral energy concepts are an excellent basis for the construction of energy-efficient buildings. In the extreme case buildings can even be self-sufficient in their energy supply. Uniting the responsibility for the overall energy and technology concept in the hands of a single contractor can help reduce frictional losses between those involved in the planning as well costs. A good example of this is the use of a simulation calculation for the prescribed demonstration of proper heat insulation. The presented projects show that it is possible to construct ecologically answerable buildings at attractively low costs. The presented concepts appear particularly convincing from the viewpoint of long-term maintenance of value and user-specific advantages such as agreeable working conditions. [Deutsch] Die konkreten Projekterfahrungen bestaetigen, dass durch integrale Energiekonzepte sowohl im Verwaltungs- als auch im Wohnungsbau hervorragende Voraussetzungen fuer energiesparende Gebaeude geschaffen werden koennen. Im Extremfall kann sogar eine autarke Energieversorgung erreicht werden. Durch Zusammenfassung der Gesamtverantwortung fuer das Energie- und Technikkonzept in einer Hand koennen Reibungsverluste zwischen den Planungsbeteiligten reduziert und Kosten gesenkt werden. Ein Beispiel hierfuer ist die Verbindung des vorgeschriebenen Waermeschutznachweises mit einer fuer alle Beteiligten wesentlich aussagekraeftigeren Simulationsrechnung. Die vorgestellten Projekte zeigen, dass oekologisch sinnvolle Gebaeude auch zu oekonomisch attraktiven Kosten erstellt werden koennen, wobei insbesondere der Aspekt des langfristigen Werterhalts und die nutzerspezifischen Vorteile, z.B. durch angenehmere Arbeitsbedingungen, fuer die vorgestellten Konzepte spricht.

    This assessment is a feasibility study according to ISO 14024. It deals with the question whether an ecolabel is suitable for wood pellet heating systems and how concrete criteria for an ecolabel for wood pellet heating plants could be specified. The study begins with a comprehensive market analysis in order to identify possible plants for which an ecolabel would make sense. In the main part of the study, the environmental relevance of the chosen plants is analysed. For this analysis, plant manufacturers were interviewed and a comparison between wood pellet heating systems and heating systems which use gas, oil or wood was carried out. On the basis of this analysis, it was possible to derive a number of criteria which were discussed with company representatives and other experts in this field. As a result of this dialogue and the investigation process as a whole, the introduction of an ecolabel for wood pellet heating plants can be recommended. Wood pellet heating systems are characterized by their high level of automatation and the use of standardized fuels with constant high quality. Thus, they reach high combustion quality with low emission rates, and risks of misuse are minimized. They may contribute to the increased use of renewable energies and thereby to the achievement of climate protection goals. The proposed certification principles comprise requirements regarding (a) the efficient energy use (efficiency factor under partial load and nominal load, plant's supplementary energy consumption), (b) emission values for CO, NO{sub x}, dust and organic substances, (c) the offer of additional services, as well as (d) requirements with regard to the operating instructions. The transcription of the label is proposed as 'Ecolabel.. because low emission and energy-efficient'. (orig.)

    Full Text Available Abstract Background Socioeconomic factors are increasingly recognised as related to health inequalities in Germany and are also identified as important contributing factors for an increased risk of acquiring infections. The aim of the present study was to describe in an ecological analysis the impact of different social factors on the risk of acquiring infectious diseases in an urban setting. The specific outcome of interest was the distribution of Rotavirus infections, which are a leading cause of acute gastroenteritis among infants and also a burden in the elderly in Germany. The results may help to generate more specific hypothesis for infectious disease transmission. Methods We analysed the spatial distribution of hospitalized patients with Rotavirus infections in Berlin, Germany. The association between the small area incidence and different socio-demographic and economic variables was investigated in order to identify spatial relations and risk factors. Our spatial analysis included 447 neighbourhood areas of similar population size in the city of Berlin. We included all laboratory-confirmed cases of patients hospitalized due to Rotavirus infections and notified between 01/01/2007 and 31/12/2009. We excluded travel-associated and nosocomial infections. A spatial Bayesian Poisson regression model was used for the statistical analysis of incidences at neighbourhood level in relation to socio-demographic variables. Results Altogether, 2,370 patients fulfilled the case definition. The disease mapping indicates a number of urban quarters to be highly affected by the disease. In the multivariable spatial regression model, two risk factors were identified for infants ( Conclusions Neighbourhoods with a high unemployment rate and high day care attendance rate appear to be particularly affected by Rotavirus in the population of Berlin. Public health promotion programs should be developed for the affected areas. Due to the ecological study

    Purpose: Since March 2007, the Standing Committee on Vaccination (STIKO) recommends HPV vaccination for all 12–17 y-old females in Germany. In the absence of an immunization register, we aimed at assessing HPV-vaccination coverage and knowledge among students in Berlin, the largest city in Germany, to identify factors influencing HPV-vaccine uptake. Results: Between September and December 2010, 442 students completed the questionnaire (mean age 15.1; range 14–19). In total 281/442 (63.6%) students specified HPV correctly as a sexually transmitted infection. Of 238 participating girls, 161 (67.6%) provided their vaccination records. Among these, 66 (41.0%) had received the recommended three HPV-vaccine doses. Reasons for being HPV-unvaccinated were reported by 65 girls: Dissuasion from parents (40.2%), dissuasion from their physician (18.5%), and concerns about side-effects (30.8%) (multiple choices possible). The odds of being vaccinated increased with age (Odds Ratio (OR) 2.19, 95% Confidence Interval (CI) 1.16, 4.15) and decreased with negative attitude toward vaccinations (OR = 0.33, 95%CI 0.13, 0.84). Methods: Self-administered questionnaires were distributed to 10th grade school students in 14 participating schools in Berlin to assess socio-demographic characteristics, knowledge, and statements on vaccinations. Vaccination records were reviewed. Multivariable statistical methods were applied to identify independent predictors for HPV-vaccine uptake among female participants. Conclusions: HPV-vaccine uptake was low among school girls in Berlin. Both, physicians and parents were influential regarding their HPV-vaccination decision even though personal perceptions played an important role as well. School programs could be beneficial to improve knowledge related to HPV and vaccines, and to offer low-barrier access to HPV vaccination. PMID:22995838

    Full Text Available How can buildings be combined with agricultural production and what are the major potential benefits and challenges for the introduction of zero-acreage farming (ZFarming in Berlin from the relevant stakeholders’ perspectives? These questions were explored through a series of interviews and stakeholder workshops held between 2011 and 2013. The aim was to identify the most suitable building-integrated farming model for the Berlin metropolitan area and to develop guidelines for the model’s successful and sustainable implementation through a stakeholder-driven approach. This paper provides an aggregated synthesis of the outcomes derived from the qualitative interviews and stakeholder workshops. As the results reveal, the stakeholders perceive potential benefits and challenges related to the issue of ZFarming in all dimensions (economic, social, environmental and political. They largely agreed on the importance of focusing on local resources, using energy-efficient production—including social and educational aspects—and developing new market structures when introducing ZFarming to the city of Berlin. The stakeholders identified urban rooftop greenhouses (RTG as the most promising farming model for Berlin. In a joint collaboration of all stakeholders, a manual for RTG was developed within the participatory innovation process that addresses the identified problems and challenges associated with future implementation and governance of RTG in Berlin and beyond.

    We aimed to systematically review the Berlin questionnaire as a screening tool for obstructive sleep apnea. We systematically searched PubMed, Embase, and Scopus databases, reviewed articles reporting the Berlin questionnaire's diagnostic utility as measured against type-1 polysomnography, and performed meta-analyses where possible. Thirty five eligible articles showed that the Berlin questionnaire's diagnostic utility varied by study population, definition of hypopnea used, and apnea-hypopnea index threshold used. It had good sensitivity and specificity for detecting clinically relevant obstructive sleep apnea as well as any obstructive sleep apnea in the sleep clinic population. Despite limited evidence, it showed modest to high sensitivity for detecting clinically relevant obstructive sleep apnea or any obstructive sleep apnea in other clinical and general population subgroups. Its specificity was relatively low. Possible reasons for variability in reported diagnostic utility of the Berlin questionnaire are multifaceted. We conclude that the Berlin questionnaire is useful as a clinical screening test and epidemiological tool in the sleep clinic population. Despite limited evidence, it likely has potential clinical and research utility in other populations. Adopting more consistent methodological definitions and focussing more on the general population and specific clinical populations to determine its usefulness as a clinical or epidemiological screening tool are recommended.

    There is an increasing demand for integrated building concepts in order to reduce energy consumption. Building design, construction and heating, ventilation and air-conditioning (HVAC) technology are decisive in this respect.

    Full Text Available En Prusse, dans les collections royales, l'attention portée à la conservation et à la restauration des peintures s’accroît au début du XIXe siècle. L’expertise des personnes impliquées se transforme considérablement à cette époque. Les peintres vernaculaires traditionnellement employés sont remplacés par des restaurateurs français et italiens recevant des commandes. Des peintres-restaurateurs allemands prennent ensuite leurs places et se regroupent dans un atelier lié au nouveau musée de Berlin. Après une période de négligence caractérisée par des actions très limitées, des restaurations plus systématiques et contrôlées sont ainsi supervisées par les autorités dans l’institution naissante.The efforts on conservation and restoration of pictures in the Prussian royal collections increased in the first decades of the 19th century. Local painters were replaced first by French and Italian restorers, then by German professionals that founded an own workshop, related to the new public art museum in Berlin.

  14. Squatting and urban renewal: the interaction of squatter movements and strategies of urban restructuring in Berlin.

    Holm, Andrej; Kuhn, Armin

    Squatting as a housing strategy and as a tool of urban social movements accompanies the development of capitalist cities worldwide. We argue that the dynamics of squatter movements are directly connected to strategies of urban renewal in that movement conjunctures occur when urban regimes are in crisis. An analysis of the history of Berlin squatter movements, their political context and their effects on urban policies since the 1970s, clearly shows how massive mobilizations at the beginning of the 1980s and in the early 1990s developed in a context of transition in regimes of urban renewal. The crisis of Fordist city planning at the end of the 1970s provoked a movement of "rehab squatting" ('Instandbesetzung'), which contributed to the institutionalization of "cautious urban renewal" ('behutsame Stadterneuerung') in an important way. The second rupture in Berlin's urban renewal became apparent in 1989 and 1990, when the necessity of restoring whole inner-city districts constituted a new, budget-straining challenge for urban policymaking. Whilst in the 1980s the squatter movement became a central condition for and a political factor of the transition to "cautious urban renewal," in the 1990s large-scale squatting — mainly in the eastern parts of the city — is better understood as an alien element in times of neoliberal urban restructuring.

    Eye tumors (choroidal melanomas, iris melanomas, and choroidal hemangiomas) are being treated with 68 MeV protons since 1998 at the Ion Beam Laboratory of the Hahn-Meitner Institute of Berlin (Germany's first proton therapy center), in cooperation with the Charite University Hospital in Berlin, Campus Benjamin Franklin. The proton beam, generated via a combination of Van de Graaff accelerator and cyclotron, is prepared by passive shaping for conformal tumor irradiation. A digital X-ray verification of the tumor location with the patient in sitting position limits the position uncertainties to a maximum of 0,3 mm. The treatment planning is performed using the program EYEPLAN. OCTOPUS, a CT-based planning program developed in cooperation with the German Cancer Research Center of Heidelberg, is under pre-clinical testing. Thus far, more than 400 patients have been irradiated. The first results are comparable to those obtained in other proton therapy centers. At the end of 2002, the University Hospital of Essen has also become a cooperation partner of the Hahn-Meitner Institute. (orig.) [de

    The purpose of the present study was to work out a proposal for the development of a new organisation concept for hard coal mining in the Ruhr District. An appropriate starting point for an inquiry into the efficacy of an organisation concept is to study those factors governing business and its social environment that have been subject to great change during the past decades. In order to provide a basis for a proposal to this end the study first presents those factors governing the social environment that are relevant to an assessment. The most important factors of influence in the present context are the individual, his conception of his work, and his self-image; technology and its impact on the course of developments; and, examined here from a theoretical viewpoint, organisational structures that have actually been adopted in the past or have been suggested in the literature. Deliberations on these three areas provide a basis for developing and discussing new organisation concepts for hard coal underground mining. (orig./HS) [Deutsch] Das Ziel dieser Untersuchung ist, einen Vorschlag zur Entwicklung einer neuen Organisationsform im Steinkohlenbergbau an der Ruhr zu erarbeiten. Ausgangspunkt fuer eine Fragestellung im Hinblick auf die Zweckmaessigkeit einer Organisationsform ist die Beobachtung der Entwicklung der Betriebs- und Umweltbedingungen, die sich im Verlauf der letzten Jahrzehnte wesentlich gewandelt haben. Um eine Basis fuer einen solchen Vorschlag zu schaffen, sind zuerst die Umweltbedingungen dargelegt worden, die fuer eine Beurteilung von Bedeutung sind. In diesem Zusammenhang sind von Einfluss im wesentlichen der Mensch und seine Beziehungen zu Arbeit und gesellschaftlichem Selbstverstaendnis, die Technik und die Auswirkungen ihrer Weiterentwicklung im Zeitablauf sowie die theoretische Betrachtung von Organisationsstrukturen, die in der Vergangenheit in die Praxis eingefuehrt bzw. in der Literatur beschrieben worden sind.

    The paper describes the use of online simulation for prognosticating plant behaviour, training plant operators, and for obtaining state data not to be obtained otherwise. Whereas, for the mathematical modelling of the process, the established approaches Activated Sludge Model (ASM) 1 and 2 could be reverted to, new methodics needed to be developed for continuous model tracking in order to solve the conflict between a large number of parameters in the model and scarce online measuring data on the spot. The result is a practicable solution which harnesses available knowledge concerning the significance of suitable parameters for model adaptation. First of all, essential demands on and objectives of a process observer for sewage treatment plants are elaborated. Then a software system is described with reference to successful pilot installations which permits model-based process control and remote monitoring of sewage treatment plant. (orig.) [German] Der Beitrag beschreibt die Nutzung der Online-Simulation fuer die Prognose des Anlagenverhaltens, das Training der Anlagenfahrer und die Gewinnung ansonsten nicht messbarer Zustandsinformationen. Waehrend fuer die mathematische Modellierung des Prozesses auf die etablierten Ansaetze ASM 1 und 2 (Activated Sludge Model) zurueckgegriffen werden konnte, musste fuer die laufende Modellnachfuehrung eine neue Methodik entwickelt werden, um den Konflikt zwischen grosser Parameteranzahl im Modell und geringer Online-Messinformation vor Ort zu loesen. Das Ergebnis ist eine praktikable Loesung, die das vorhandene Wissen um die Signifikanz zur Modellanpassung geeigneter Parameter ausnutzt. In den folgenden Ausfuehrungen werden zunaechst wesentliche Anforderungen und Zielstellungen eines Prozessbeobachters fuer Klaeranlagen herausgearbeitet. Unter Bezugnahme auf erfolgreiche Pilotinstallationen wird anschliessend ein Software-System vorgestellt, das eine modellgestuetzte Betriebsfuehrung und Fernueberwachung von Klaeranlagen

    The application of modern simulation tools offering additional support during the vehicle development process is accepted to a large extent by most car manufacturers. Just like new model-based control strategies, these simulation investigations require very accurate - and thus very complex - models of vehicle dynamics, which can be processed in real time. As an example of such a vehicle model, this article describes a real-time vehicle simulation model which was developed at the Institute of Automatic Control at Darmstadt University of Technology, in co-operation with the ITDC of the Adam OPEL AG. By applying modern adaptation techniques, this vehicle model is able to calculate onboard the important variables describing the actual driving state even if the environmental conditions change. (orig.) [German] Der Einsatz von Simulationswerkzeugen zur Unterstuetzung der Fahrzeugentwicklung hat sich bei den meisten Automobilherstellern weitgehend durchgesetzt. Ebenso wie neuartige modellbasierte Regelstrategien verlangen diese Simulationsuntersuchungen nach immer exakteren - und damit komplexeren - fahrdynamischen Modellen, die in Echtzeit ausgewertet werden. Als Beispiel fuer ein solches Gesamtfahrzeugmodell beschreibt dieser Beitrag ein echtzeitfaehiges Modell fuer die Bewegung des Fahrzeugs um alle drei Hauptachsen, das am Institut fuer Automatisierungstechnik der TU Darmstadt in Kooperation mit dem Internationalen Technischen Entwicklungszentrum (ITEZ) der Adam Opel AG entwickelt wurde. Es ist durch den Einsatz von Adaptionsmethoden in der Lage, wichtige fahrdynamische Zustandsgroessen im Fahrzeug auch unter veraenderlichen Umgebungsbedingungen zu ermitteln. (orig.)

    To remain internationally competitive company managements in the German coal mining industry must effectively use market opportunities on foreign coal markets. It is shown below that there can be no uniform, globally successful marketing strategy for the international coal market. Instead different marketing strategies specific to the countries should be implemented for commitments in the individual coal-producing countries. Such marketing strategies should be based on situation analyses of the individual coal-producing countries, which should be supplemented by opportunity/risk analyses. The systematology introduced for this purpose in based on the model of the product life cycle. The description concentrates on the coalproducing sector. (orig.) [Deutsch] Prognosen renommierter Institutionen lassen erwarten, dass die Steinkohlenbranche weltweit in den naechsten Jahrzehnten noch Wachstumspotentiale besitzt. Durch Nutzung dieser Potentiale im Zug einer Internationalisierung kann die deutsche Steinkohlenbranche schrumpfende Inlandsproduktion ersetzen. Im vorliegenden Beitrag wird gezeigt, dass es hierfuer keinen Koenigsweg einer einheitlichen, global erfolgreichen Marketingstrategie fuer den Weltsteinkohlenmarkt geben kann. Statt dessen sind laenderspezifisch differenziert gestaltete Marketingstrategien fuer Engagements in den einzelnen Kohlelaendern umzusetzen. Solche Marketingstrategien sollten auf Situationsanalysen der einzelnen Kohlelaender beruhen, die durch Chancen-/Risikenanalysen zu ergaenzen sind. Die hierzu vorgestellte Systematik beruht auf dem Modell des Produktlebenszyklus. Im Mittelpunkt der Darstellung steht der steinkohlenproduzierende Bereich. Basis fuer internationale Engagements sind vorhandene Kernkompetenzen. Zur erfolgreichen Realisierung solcher Strategien scheint die Organisationsform der Netzwerk-Organisation zweckmaessig zu sein.

    The interaction between environmental factors and genetic determinants is crucial for the development of malignant tumours. However, the hereditary factors involved in the development of cancer that have been recognised so far are only responsible for at the most ten percent of tumours. It is still a matter of dispute whether the remaining 90 percent - so-called sporadic tumours - really have a cause that is free of genetic influence. There are good reasons for believing that there are a large number of genes in the human genome that confer resistance or susceptibility for tumorigenesis, and thus lead to natural genetic variability. (orig.) [German] Die Wechselwirkung von Umweltfaktoren und genetischen Determinanten ist entscheidend fuer die Entstehung von malignen Tumoren. Die bisher bekannten an der Krebsentstehung beteiligten erheblichen Faktoren sind allerdings fuer hoechstens zehn Prozent aller auftretenden Tumoren verantwortlich. Nach wie vor umstritten ist, ob die verbleibenden 90 Prozent - die sogenannten sporadischen Tumoren - tatsaechlich eine Ursache ohne erhebliche Komponente haben. Es gibt aber gute Gruende anzunehmen, dass im menschlichen Erbgut eine Vielzahl von Genen existiert, die Resistenz beziehungsweise Empfindlichkeit (Suszeptibilitaet) fuer die Tumorigenese vermitteln und so zu der natuerlichen genetischen Variabilitaet fuehren.

The collection includes material from throughout the world, with a focus on former German colonies. Notes on collectors and localities are provided where appropriate. Type material for 42 Recent species or subspecies is present; all described in the early 20th century by Karl Verhoeff. However, only seven of these names remain valid with the other thirty-five currently regarded as junior synonyms. The collection in its entirety includes material from nineteen currently valid species, making up about 20% of the known world fauna. The type of a fossil species in Eocene Baltic amber is also listed for completeness.

    As part of the Berlin Deinstitutionalisation Study, quality of life was assessed in 142 patients at two points of time. Discharged patients were reassessed one year after discharge. Patients who stayed in hospital were reinterviewed 1 1/2-2 years after the initial assessment. Discharged patients had more leisure activities, more often a "good friend", and more frequent social contacts. They were less often victim of a crime within the last year. In a cross-sectional comparison, they were significantly more satisfied with their life than patients who were still in hospital. In the latter group, only satisfaction with mental health improved significantly between first and second interview. Discharged patients became significantly more satisfied with their life in general, with leisure activities, with accommodation, and with mental health between initial assessment and follow-up. The findings demonstrate an improvement of quality of life in long-term hospitalised patients after discharge.

    The aim of this research project is to identify, characterize and quantify natural attenuation (NA) processes in groundwater affected by emissions of abandoned waste disposal sites in Berlin-Kladow/Gatow, Germany. It is part of the funding priority called KORA established by the Federal Ministry for Education and Research (BMBF) to explore the extent to which NA can be used for remedial purposes for varied forms of soil and groundwater contamination. Information on the emission behaviour of individual parameters is generated on the basis of hydrogeochemical comparison of 20 years old and new data. Using groundwater-modelling and CFC-analysis, information on the transport and retention of pollutants in groundwater is compiled. The microbial colonization of contaminated aquifers is characterized by molecular biological methods [polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE)] to differentiate between contaminated and not contaminated zones.

    The Berlin Brain-Computer Interface Brain-Computer Interface (BBCI) uses a machine learning approach to extract user-specific patterns from high-dimensional EEG-features optimized for revealing the user's mental state. Classical BCI applications are brain actuated tools for patients such as prostheses (see Section 4.1) or mental text entry systems ([1] and see [2-5] for an overview on BCI). In these applications, the BBCI uses natural motor skills of the users and specifically tailored pattern recognition algorithms for detecting the user's intent. But beyond rehabilitation, there is a wide range of possible applications in which BCI technology is used to monitor other mental states, often even covert ones (see also [6] in the fMRI realm). While this field is still largely unexplored, two examples from our studies are exemplified in Sections 4.3 and 4.4.

    In 1919 the Prussian Ministry of Science, Arts and Culture opened a dossier on "Einstein's Theory of Relativity." It was rediscovered by the author in 1961 and is used in conjunction with numerous other subsequently identified 'Einstein' files as the basis of this fascinating book. In particular, the author carefully scrutinizes Einstein's FBI file from 1950-55 against mostly unpublished material from European including Soviet sources and presents hitherto unknown documentation on Einstein's alleged contacts with the German Communist Party and the Comintern. Siegfried Grundmann's thorough study of Einstein's participation on a committee of the League of Nations, based on archival research in Geneva, is also new. This book outlines Einstein's image in politics and German science policy. It covers the period from his appointment as a researcher in Berlin to his fight abroad against the "boycott of German science" after World War I and his struggle at home against attacks on "Jewish physics" of which he was made...

    Health and fitness among children and adolescents is a subject currently receiving public attention. This article focuses on the fitness of German pupils (third and fourth grades) in five schools in Berlin with widely differing social catchment areas as well as children from differing social...... the fitness level of the pupils and the education level of the parents. According to our results, fitness and physical skills are, at least to a certain extent, socially inherited. The fitness differences found in the different schools can be explained partly by the different social back ground...... backgrounds. Besides an orthopaedic examination and measurements of height and weight, we tested the children's motor skills. In addition, a survey was carried out among pupils and their parents. For this purpose, questionnaires were developed which, besides furnishing demographic data, also provided...

    2016-11-01

    Full Text Available To date, the treatment of immune-mediated kidney diseases has only marginally benefited from highly specific biological drugs that have demonstrated remarkable effects in many other diseases. What accounts for this disparity? In April 2016, the International Society of Nephrology held a Nexus meeting on Translational Immunology in Nephrology in Berlin, Germany, to identify and discuss hurdles that block the translational flow of target identification, and preclinical and clinical target validation in the domain of immune-mediated kidney disease. A broad panel of experts including basic scientists, translational researchers, clinical trialists, pharmaceutical industry drug developers, and representatives of the American and European regulatory authorities made recommendations on how to overcome such hurdles at all levels of the translational research process. The results of these discussions are presented here, which may serve as a roadmap for how to optimize the process of developing more innovative and effective drugs for patients with immune-mediated kidney diseases.

  12. Managing Cultural Diversity in Federal Germany: Bavaria and Berlin as Classic Antagonists

    Directory of Open Access Journals (Sweden)

    Caroline Schultz

    2015-11-01

    Full Text Available Due to the type of federalism applied in Germany the level of analysis best suited for studying integration is that of the 16 Länder. For comparing the approaches of two of these - Bavaria and Berlin - in managing migration-related diversity, the paper uses a double differentiation as analytical starting point. The first refers to the bulk of literature of different national models of integration and proposes two ideal types of integration/diversity policy. The second differentiation seizes the suggestion that integration in some areas of life is socially much more consequential than in others with the consequence that state intervention in these areas is much easier to justify from a normative point of view. From the descriptive comparison it becomes clear that both Länder, though coming from rather diverging starting points, by now employ hybrid strategies to accommodate or manage different aspects of cultural diversity.

    2015-09-01

    Full Text Available Social segregation is a subject common in contemporary studies of metropolitan areas. Until recently, studies of segregation focused on the distribution of ethnic groups, immigrants, and the poor. Today, they also cover additional indicators such as demographic properties, education, and affiliation with social and professional categories, which can also serve to determine the causes of the segregation (including the self-segregation of the rich. This article aims to point out the measures of segregation that present the segregation levels in the most complete manner, along with their application in the context of three European metropolitan areas: Warsaw, Berlin, and Paris. The first part of the article is a review of the existing approaches to segregation measures, followed by the selection of research method, presentation of the analysis’ results, and evaluation of the applied methods; presenting the opportunities and limitations in research of the social segregation phenomenon.

  14. Mainstreaming Urban Interventionist Practices: the Case of the BMW Guggenheim Lab in Berlin

    2014-08-01

    Full Text Available The paper examines how practices of urban intervention have entered the mainstream by discussing the case of the BMW Guggenheim Lab. Financed by the German BMW group and realised by the Solomon Guggenheim Foundation, the project addresses issues of contemporary urban life in the form of a ‘mobile laboratory’ with an explicit emphasis on participatory forms of urban intervention. The Lab’s temporary residence in Berlin in 2012 encountered fierce protests from residents and activist groups.I revisit the ensuing public debates and discuss the impact they had on the project. Drawing on in-depth interviews with people involved in the Lab the various notions of participation underlying the project are examined. It is shown that the Lab generated new and unexpected encounters and individual experiences. However, for solving actual problems the debates and experiments held at the Lab were too general, too exclusive and too short-lived to be of lasting relevance.

    Engstrom, Eric J

    2006-01-01

    From the 1780s to the 1830s, physicians at the Charité hospital in Berlin conducted clinical trials designed to test the therapeutic effectiveness of animal magnetism. This study draws on those trials to investigate the practical and discursive deployment of the magnetist's body. It argues that that body--and the moral problems it came to pose--were increasingly purged from medical practice and discourse. Whereas in the 1790s the plausibility of therapeutic claims about animal magnetism demanded recourse to the magnetic practitioner's body, by the 1830s the embodied evidence on which those claims rested had lost it's persuasive power and been relegated to the netherworld of quacks and charlatans.

    Soon after announcement of the first American ether anesthesias in 1846 one started to anesthetize with ether in Europe. The first ether anesthesia in Germany took place on January 24th, 1947, and was given by Johann Ferdinand Heyfelder in Erlangen. Two weeks later the first ether anesthesia in Berlin was given on February 6th, 1847, by the orthopaedic surgeon Heimann-Wolff Berend. On February 12th, 1847, the surgeon Johann Friedrich Dieffenbach used ether to anesthetize a patient in the Berlin university hospital. Still in 1847 he published his book "The Ether against Pain" which used to be the standard textbook of anesthesia in Germany for many years to come. On February 15th, 1847, Johann Christian Jüngken operated his first patient under ether anesthesia in the surgical department of the Charité hospital assisted by Rudolf Virchow. Since then several famous Berlin surgeons influenced the development of modern anesthesia until the middle of the 20th century. The nitrous oxide bottle was introduced into practice by the Barth company in cooperation with the dentist Carl Sauer and Kurt Schimmelbusch introduced his mask for ether anesthesia. Carl Ludwig Schleich reported at the German congress of surgery in 1894 about his first experience with infiltration anesthesia. Spinal anesthesia developed by August Bier in Kiel was improved during his time in Berlin.

    Requiring PaO2/FiO2 ratio (PF) to define ARDS may bias towards children with cardiovascular dysfunction and hypoxemia. We sought to evaluate (1) the Berlin definition of ARDS in children using PF; (2) the effect of substituting SpO2/FiO2(SF) ratio; (3) differences between patients with and without arterial blood gases; and (4) the ability of SpO2 and PaO2 indices to discriminate ICU mortality. Single center retrospective review (3/2009-4/2013) of mechanically ventilated (MV) children. Initial values for PF, SF, oxygenation index (OI), and oxygen saturation index (OSI) after intubation and average values on day 1 of MV were analyzed against ICU mortality, subgrouped by Berlin severity categories. Of the 1,833 children included, 129 met Berlin PF ARDS criteria (33 % mortality); 312 met Berlin SF ARDS criteria (22 % mortality). Children with a PaO2 on day 1 of MV had higher mortality and severity of illness, were older, and had more vasoactive-inotropic infusions (p risk stratification, and should be considered for severity of illness scores and included in a pediatric-specific definition of ARDS. Multicenter validation is required.

    Forensic radiology has become a common modality in many forensic practices around the world. Here, we report and compare the usage patterns in the cities of Melbourne, Australia, and Berlin, Germany, using 16 multislice scanners in two large forensic facilities with both machines integrated in the mortuary. While in Melbourne all bodies receive a full body computed tomography (CT) scan resulting in nearly 5,000 scans per year, the situation differs in Berlin where approximately 250 state prosecutor sanctioned cases are scanned per year. While in Melbourne the CT scanner is an integral element of the process of determining whether further examinations will follow, in contrast in Berlin all cases proceed to autopsy irrespective of the findings from the CT scan. While pathologists in Berlin receive on site training to use the CT scanner by a highly experienced forensic pathologist who has previously been involved in the Virtopsy(®) program in Switzerland, training of pathologists in Melbourne is multifaceted. A radiologist with extensive experience in the forensic environment is employed part time at the institute in Melbourne and provides radiology lectures including topics such as postmortem artifacts, regional anatomy, and neuroradiology. CT is gaining acceptance as a useful modality for presenting information to the courts and juries, as well as providing an easily accessible platform to review cases and initiated research projects.

  1. Indoor heat stress: An assessment of human bioclimate using the UTCI in different buildings in Berlin

    Full Text Available Because humans spend most of their time indoors and can be negatively affected by unfavourable thermal environments, the assessment of indoor heat stress is an important issue for public health care. To characterise indoor human bioclimate, the Universal Thermal Climate Index (UTCI was used. UTCI values were calculated from measurements of air temperature and air humidity in 16 rooms in Berlin during the summer months of 2011 and 2012. A constant air velocity of approximately 0.3 m/s and a metabolic heat production of 135 W/m2 were assumed. The mean radiant temperature was set to the air temperature. Because the mean air humidity was below or slightly above 50 %, the calculated UTCI values were mostly lower than the air temperatures. In summer 2012, the mean UTCI values ranged from 22.2 °C to 27.1 °C, and the maximum UTCI values ranged from 24.7 °C to 35.6 °C. Whereas only minor differences were found between rooms located within comparable buildings in different districts of Berlin, pronounced variations of the UTCI values were detected in two adjoining buildings, with differences up to 8.6 K for the daily minimum, 9.8 K for the daily mean and 12.2 K for the daily maximum UTCI between different rooms. These variations can be explained by differences in the structures of the two buildings, floor level and aspect. The UTCI values were also used to determine the occurrence of moderate and strong heat stress. Only two rooms showed no thermal stress, while strong heat stress was detected in three rooms.

    The group at Klinik Berlin/Charite University Hospital in Berlin, Germany, began studies to promote motor recovery after stroke in the early 1990s. Following the introduction of treadmill training with partial body-weight support, the group designed an electromechanical gait trainer, GT I, based on movable foot plates that relieve therapist effort (e.g., when assisting the movement of the paretic limbs) and intensify patient gait training (GT). Preliminary results of a recent multicenter trial of 155 acute stroke patients showed that the GT I effectively promotes gait ability and competence in activi ties of daily living. The experimental group received 20 min of GT and 25 min of physiotherapy (PT) and the control group received 45 min of PT every day for 4 weeks. The laboratory's next step was the HapticWalker, a robotic walking simulator with freely programmable foot plates so that patients can, for example, additionally train for stair climbing and perturbations. The foot plates can be operated in full guidance or compliance control modes, thus reducing foot support according to the patient's learning success. For the severely affected upper limb, the laboratory's computerized arm trainer, called the Bi-Manu-Track, enables bilateral practice of forearm pronation/supination and wrist flexion/extension. Compared with electrical stimulation of the paretic wrist extensors, acute stroke patients with severe arm paresis (n = 44) had significantly more upper-limb muscle strength and control at the end of the 6-week intervention period and at follow-up. The laboratory's most recent and cost-effective development, the Nudelholz, is a purely mechanical device that bilaterally trains the shoulder, elbow, and wrist joints. It is intended for home therapy.

    Protective structures for works of art or antique artefacts have a long architectural tradition and have been known in Germany since the 19th century. The effect of such covers on the microclimate around artworks of natural stone, and hence, their protective capability are insufficiently documented and understood. In 2007, an inter-disciplinary model project and part of a pilot study coordinated by the Berlin State Office for the Protection of Monuments was planned with the aim of developing an innovative winter covering system for marble statuaries located on the Schlossbrücke in Berlin. Such a system would need to fulfil the various requirements for structural stability, aesthetics, climate and practical use. This applied research represents the first complex scientific study of the sustainability of a winter covering system. A climate monitoring system was designed to create a dense database for the numerical prediction of the effect of protective systems, and to compare the given climate conditions to the known factors influencing the marble deterioration. Based on these findings a prototype of an innovative shelter was designed and tested. The project shows, that beside a temporary covering regular inspection and maintenance combined with regular cleaning ensures an effective and sustainable protection of marble sculptures. Such a maintenance program is the precondition for preserving the sculptures of the Schlossbrücke as a historical ensemble. Important scientific results of the project are transferable to similar objects of Carrara marble. The results throw a new light on the conventional protection of such objects and leads to a discussion on the necessity of an all-season protection.

    Within the frame of this project, a concept for setting up exemplary emission inventories for water was put forward. An overview is given of the international activities on emission inventories and the status of national emission inventories. Based on the data situation in Germany, it was necessary to include both plant-specific, aggregated and calculated data of the point sources in the inventories. Due to their increasing significance, diffuse material emissions into water were also taken into account. Based on the conceptual work, exemplary emission inventories were compiled for nitrogen, phosphorous and adsorbable organic combined halides (AOX) as well as the heavy metals arsenic, cadmium, chrome, copper, mercury, nickel, lead and zinc. These were evaluated according to the areas of origin (sectors) or the emission paths as well as according to the large river basins Danube, Rhine, Ems, Weser, Elbe, Oder, North Sea and Baltic Sea. In addition, lists of the ten largest industrial direct dischargers were compiled. (orig.) [German] Im Rahmen dieses Vorhabens wurde ein Konzept fuer die Erstellung von beispielhaften Emissionsinventaren fuer Gewaesser erarbeitet.

    New radiobiological findings like genomic instability and genetic predisposition did not only give an impetus to research activities but prompted also the assumption that radiation protection has to be revised. This paper outlines possible consequences for the practically relevant area of low doses. It begins with a discussion of damage distributions after low dose exposure including a critical evaluation of the applicability of this quantity. The radiobiological findings which started the present discussion are briefly summarised as well as the results of new studies in genetics. Possible consequences might be envisaged for the evaluation of epidemiological investigations, both with regard to radiation related cancer risk as well as to the possible occurrence of radiation-related non-cancer diseases. In conclusion it is stated that the new findings will not lead to an upward revision of present risk factors and hence there is no need for fundamental changes of the current system of radiation protection. (orig.) [German] Neuere strahlenbiologische Erkenntnisse wie genomische Instabilitaet und genetische Praedisposition haben nicht nur die Forschung befluegelt, sondern auch die Vermutung genaehrt, dass neue Ueberlegungen zum Strahlenschutz angestellt werden muessen. In diesem Beitrag werden moegliche Konsequenzen fuer den praktisch wichtigen Bereich niedriger Dosen diskutiert. Am Anfang steht zunaechst eine Betrachtung ueber die Schadensverteilung im niedrigen Dosisbereich, die eine kritische Wertung der Anwendbarkeit dieser Groesse einschliesst. Die strahlenbiologischen Befunde, welche die Diskussion angestossen haben, werden ebenso skizziert wie die genetische Ausgangslage. Konsequenzen werden gesehen fuer die Bewertung epidemiologischer Studien sowohl fuer die Abschaetzung des Krebsrisikos als auch der Moeglichkeit der Strahlenbedingtheit anderer Erkrankungen. Als Schlussfolgerung wird festgestellt, dass die neuen Befunde nicht zu einer Erhoehung der gegenwaertig

    Nephrogenic systemic fibrosis (NSF) is a systemic disease with a 5% mortality which was first described in 1997 and which only occurs in patients with severely impaired renal function (GFR <30 ml/min per 1.73 m{sup 2}) and for which an association with previous administration of several Gd-chelates has been observed. According to retrospective case control studies the odds ratio for a patient with severely impaired renal function to develop NSF was increased by a factor of 22-32 when gadodiamide was administered. At this time there are approximately 250 confirmed cases of NSF of which 177 are associated with the administration of gadodiamide and 78 are associated with gadopentetate dimeglumine. This review article elucidates the postulated pathogenesis of NSF and provides an overview of the published statements and recommendations from international regulatory authorities and from international advisory boards. Even though the pathogenesis is not completely understood at this time, the European Pharmacovigilance Working Party has decided that gadodiamide and gadopentetate dimeglumine must not be used in high-risk patients. Other Gd-containing contrast agents should only be administered after thorough assessment of the indication and with minimized Gd dose. In the USA, the FDA has issued a black box warning for Gd-containing contrast agents. (orig.) [German] Die nephrogene systemische Fibrose (NSF) ist eine 1997 erstmals beschriebene systemische Erkrankung mit einer 5%igen Mortalitaet, die bislang ausschliesslich bei Patienten mit terminaler Niereninsuffizienz (glomerulaere Filtrationsrate [GFR] <30 ml/min/1,73 m{sup 2}) aufgetreten ist und fuer die eine Assoziation mit der vorherigen Verabreichung verschiedener Gadolinium- (Gd-)haltiger MR-Kontrastmittel beobachtet wurde. Laut retrospektiver Fall-Kontroll-Studien war die Odds Ratio fuer die Entwicklung einer NSF bei Patienten mit stark eingeschraenkter Nierenfunktion 22- bis 32-fach hoeher, wenn Gadodiamid

    Purpose: For preoperative staging of colorectal cancer a CT scan is frequently performed. This report examines the sensitivity of CT for regional lymph node metastasis of colorectal cancer using different criteria. Materials and methods: Preoperative CT scans of 153 patients with colorectal cancer were analyzed using different criteria for N1. The results were then compared to the postoperative histological findings. Results: For N1=lymph nodes (LN)>1 cm the sensitivity was 47%. For N1=LN>1 cm or an increased number of LN<1 cm the sensitivity was 71%. In patients with a primary tumor seen on CT, sensitivity rose to 87%. Discussion: Evidence of regional nodal metastatic disease is only relevant for rectal cancer, colon polyps, and for locally excised tumors when considering present surgical concepts for the treatment of colorectal cancer. In these cases CT analysis using the broadened criteria for N1 proposes a valuable argument regarding possible preoperative radiotherapy or an operative revision. (orig.) [Deutsch] Die Sensitivitaet fuer den Nachweis regionaerer Lymphknotenmetastasen kolorektaler Karzinome wurde unter Anwendung verschiedener Kriterien fuer das N1-Stadium an Patienten mit histologisch gesichertem Lymphknotenbefund untersucht. Fuer das Kriterium N1=Lymphknoten (LK)>1 cm betrug die Sensitivitaet 47%. Fuer N1=LK>1 cm/vermehrte Anzahl LK<1 cm war sie 71%, bei erkennbarem Primaertumor sogar 87%. Unter Beruecksichtigung der derzeit geltenden operativen Therapiekonzepte ist der Nachweis von regionaeren Lymphknotenmetastasen nur bei Rektumkarzinom bzw. fuer Kolonpolypen oder fuer lokal exzidierte Karzinome fuer das therapeutische Vorgehen relevant. In diesen Faellen leistet die CT mit den erweiterten Kriterien fuer ein N1-Stadium trotz hoeherer falsch-positiver Raten eine wertvolle Hilfestellung fuer die Entscheidung ueber eine neoadjuvante Bestrahlung oder eine Nachresektion.

    The roof interstice at the New Museum in Berlin is used as an example to illustrated that, for large, continuous air spaces with external glazing, conventional design tools are often inadequate for answering strategic questions relating to building physics (condensation or ice formation) or building services design (ventilation dimensioning). This may lead to oversizing or design uncertainty. An integrated design procedure that goes beyond the limits of the individual fields involved would be superior to the conventional approach stipulated by the Fee Structure for Architects and Engineers, which is split into separate specialist areas. This is the only way of resolving interface issues between the individual fields. However, such an approach requires higher-level design tools and is associated with greater design effort. Nevertheless, the example of the reconstruction of the New Museum in Berlin shows that increased design effort can not only avoid design uncertainty, but can also lead to significantly reduced demand for building services hardware. The additional design expense is therefore often more than compensated through savings. (Abstract Copyright [2004], Wiley Periodicals, Inc.) [German] Am Beispiel des Glasdach-Zwischenraums des Neuen Museums in Berlin wird aufgezeigt, dass die herkoemmlichen Planungswerkzeuge bei grossen, zusammenhaengenden Luftraeumen mit Aussenverglasungen haeufig nicht ausreichen, um uebergreifende Fragestellungen der Bauphysik (Tauwasseranfall bzw. Eisbildung) und der TGA-Planung (Dimensionierung der Lueftung) ausreichend zu beantworten. Dies kann zu Ueberdimensionierungen und Planungsunsicherheiten fuehren. Eine dem herkoemmlichen Planungsverlauf nach HOAI mit aufgeteilten Leistungsbildern deutlich ueberlegene Vorgehensweise ist in der integralen Planung ueber die Grenzen der einzelnen Fachbereiche hinaus zu sehen. Nur so kann die Schnittstellenproblematik zwischen den einzelnen Fachbereichen aufgeloest werden. Ein solches Vorgehen

    The Forest State Report 2012 systematically records the health status of the forest resources in the country on a scientific basis. Environmental information is measured, recorded and evaluated in the context of forest environmental monitoring using a measuring network. More than a third of the forest area has suffered significant damage. The share of undamaged forest areas has declined by almost one third to 26 percent since last year. Compared to the previous year, the crown damage increased by an average of 2.5 percentage points. More important, however, is the fact that for the two main tree species spruce and beech since the turn of the millennium, there has been a marked increase in the damage intensity for all age groups.

    In Baden-Wuerttemberg, the state of forests has been recorded since the 1980s in the course of an annual forest status report. In 2015, a decline in forest damage can be reported. As an indicator for the evaluation of the forest state, the crown condition of the trees applies. The average crown defoliation has been reduced by two percentage points to around 24 percent, while the share of healthy forest areas increased by five percentage points to a total of 29 percent. The clearly damaged forest areas decreased by six percentage points to 36 percent. Concerns are causing a relatively new fungus disease in the tree species ash, the ash dieback.

    At present, selection of procedures for inservice inspection has to take into account the legal basis, i.e. the existing regulatory codes, and the practical aspects, i.e. experience and information obtained by the general, initial inservice inspection or performance data obtained by the latest, recurrent inspection. However, regulatory codes are being reviewed to a certain extent in order to permit integration of technological progress. Depending on the degree of availability in future, of inspection task-specific, sensitive and qualified NDE techniques for inservice inspections (`risk based ISI`), the framework of defined inspection intervals, sites, and detection limits will be broken up and altered in response to progress made. This opens up new opportunities for an optimization of inservice inspections for proof of component integrity. (orig./CB) [Deutsch] Zur Zeit muss sich die Auswahl der Pruefverfahren an den gueltigen Regelwerken und, da es sich um wiederkehrende Pruefungen handelt, an der Basispruefung bzw. der letzten wiederkehrenden Pruefung orientieren. Jedoch vollzieht sich zur Zeit eine Oeffnung der Regelwerke, mit der man auch der Weiterentwicklung der Prueftechniken Rechnung traegt.

    Increasing competition and changing markets in the energy sector make new demands on cost management and at the same time on the quality to be provided by the costing systems. The process cost calculation used today in various branches of industry is able to contribute - by orientating itself to processes and chains of delivered value - to an assignment of costs doing more justice to the causes so that costing information with improved meaningfulness is available for entrepreneurial decisions. The authors introduce process cost calculation and illustrate its function using a practice-related example for its application. Potential fields of utilisation in the electricity supply enterprises are subsequently shown. (orig.)

  1. A spatial and seasonal description of return-levels for the Berlin-Brandenburg region (Germany)

    Extreme precipitation events have a strong impact on the environment, society and economy. Besides the direct effect, e.g. damage due to hail, extreme precipitation can cause flood events, mudslides and increased erosion, which in turn lead to serious damage. Typically, return levels derived from annual maxima of daily precipitation sums are used for the design of hydraulic structures or for risk assessment in insurance companies. Seasonally or monthly resolved return levels are rarely considered, although they provide additional information: the higher temporal resolution can be beneficial for risk management, e.g. for agriculture or tourism sector. In addition, annual return levels derived from monthly maxima offer lower uncertainties, since a larger data basis are used for estimation. Here, the generalized extreme value distribution (GEV) is used to calculate monthly resolved return levels for 323 stations in the region Berlin-Brandenburg (Germany). Instead of estimating the parameters of the GEV for each month separately, the seasonal variation is captured by harmonic functions. This natural approach is particularly suitable for an efficient characterization of the seasonal variation of extreme precipitation. In a first step, a statistical model is developed for each station separately to estimate the monthly return levels. Besides the seasonal smoothness, also smoothness in space is exploited here. We use functions of longitude, latitude and altitude to describe the spatial variation of GEV parameters in the second step. Thus, uncertainty is reduced at gauges with short time series and estimates for ungauged sites can be obtained in a meaningful way.

  2. Rearticulating the Experience of War in Anonyma: Eine Frau in Berlin

    2012-10-01

    Full Text Available Situating itself in the field of cultural memory studies, this article traces the slow emergence in German historical discourse of the narrative of an anonymous German woman who survived the Soviet occupation of Berlin in 1945. I will, firstly, conceptualize the historical condition of the Anonyma as a precarious liminal sphere of transition between competing sovereignties that dislodged her political status as citizen and reconstituted her as bare life in the sense of Agamben. Secondly, I direct focus to the relationship between the personal story of the Anonyma and a historical Master narrative pertaining to the period. The article argues for a close connection between the woman’s form of resistance that aimed at replacing unchecked rape with a form of coerced prostitution to reassert limited control over the borders of her body, and the negative reception her diary received after a first publication in Germany in 1959. Her story implicitly challenges a hegemonic discourse of war that treats mass rape as mainly an assault on the nation’s male defenders and that silences the victims’ traumatic experiences with reference to collective guilt and individual shame or treason.

    New and higher standards in the EU water framework directive necessitate advanced treatment of secondary effluents for reduction of trace organic compounds (TrOCs) and nutrients before the discharge into receiving surface waters. Due to its dual function as oxidant and coagulant, ferrate is considered as a promising alternative for tertiary treatment. The oxidation of selected TrOCs and simultaneous flocculation of phosphates by ferrate was tested in batch experiments with secondary effluent from Berlin Ruhleben. The concentrations of carbamazepine (CBZ) and diclofenac were reduced by >90% with ferrate dosages of 6 mg/L as Fe. CBZ was transformed to 1-(2-benzaldehyde)-4-hydro-(1H,3H)-quinazoline-2-one, which is known as the major product from the reaction of CBZ with ozone. In contrast to ozonation, no further transformation of this product was observed. The concentration of ibuprofen was not reduced by ferrate treatment. For efficient removal of 60-100 μg/L phosphate-P to values <20 μg/L, ferrate dosages of 3-4 mg/L as Fe were sufficient.

  4. Architectural practice and theory: the case of Bruno Taut's house in Berlin-Dahlewitz

    2017-06-01

    Full Text Available In 1926 Bruno Taut built his own house in Berlin-Dahlewitz. The German architect had already declared his ideas of housing in the book Die neue Whonung (1924 exemplifying the new concept of modern living-style, according to Neues Bauen. In other theoretical writings he defines the Neues Bauen in relation with new needs, tendencies and aesthetics of architecture, referring to important issues as climate, topography and tradition. The book Ein Whonhaus (1927 stigmatizes the coeval construction process of his house: the thirteen chapters are a detailed analysis which give evidence to every technological and morphological choice. Taut focuses on the relationship between architecture and landscape, type of furniture, functional plan layout, use of glass; especially he enlightens the reader as to the use of colour as a construction material. The house has an unconventional shape, it is a quarter of a circle; in his writings the architect painstakingly explains the impressive plan. With the book Ein Whonhaus Taut delivers to memory his home design, transforming process and ideas related to the modern house. He breaks through conventions and changes the notions of what Modernism could produce. The paper highlights the theoretical production related to the architect’s own house as praxis for doing architecture, emphasizing Taut’s contribution to a dialectic mutual relationship between theoretical and architectural practice, in order to achieve a more conscious and effective design process.

    The new cold neutron radiography instrument CONRAD is a multifunctional facility for radiography and tomography with cold neutrons at Hahn-Meitner Institut, Berlin. It is located at the end of a curved neutron guide, which faces the cold-neutron source of the BER-II research reactor. The geometry provides a cold-neutron beam with wavelengths between 2 and 12 Å. Two measuring positions are available for radiography and tomography investigations. The first one is placed at the end of the guide and it is optimized for in situ experiments in which a high neutron flux is required. The available flux at this position is approximately 10 8 cm -2 s -1. The second measuring position uses a pin-hole geometry which allows better beam collimation ( L/ D up to 1000) and higher image resolution in the range of 200 μm in the CCD based detector system (10×10 cm 2). The use of cold neutrons for radiography purposes increases the image contrast and improves the sensibility e.g., the detection of small amounts of water and hydrogen-containing materials in metal matrixes. On the other hand the cold-neutron beam can be modified easily by using diffraction and neutron optical techniques. This enables to perform radiography and tomography experiments with more sophisticated measuring techniques. Recent examples of research and industrial applications will be presented.

    Some patients presenting with acute respiratory failure and meeting the Berlin criteria for acute respiratory distress syndrome (ARDS) lack exposure to common risk factors (CRF). These so-called ARDS mimickers often lack histological diffuse alveolar damage. We aimed to describe such ARDS mimickers lacking CRF (ARDS CRF-) in comparison with others (ARDS CRF+). Retrospective study including all patients receiving invasive mechanical ventilation for ARDS admitted to the intensive care units (ICUs) of two tertiary care centers from January 2003 to December 2012. The prevalence of ARDS CRF- was 7.5 % (95 % CI [5.5-9.5]; n = 50/665). On the basis of medical history, bronchoalveolar lavage fluid cytology, and chest CT scan patterns, four etiological categories were identified: immune (n = 18; 36 %), drug-induced (n = 13; 26 %), malignant (n = 7; 14 %), and idiopathic (n = 12; 24 %). Although the ARDS CRF- patients had a lower logistic organ dysfunction score (4 [3-8] vs. 10 [6-13]; p risk of mortality. For such atypical ARDS, a complete diagnostic workup, including bronchoalveolar lavage fluid cytology and chest CT scan patterns, should be performed to identify those patients who might benefit from specific therapies, including corticosteroids.

    The Extreme Environment Diffractometer (EXED) is a new neutron time-of-flight instrument at the BER II research reactor at the Helmholtz-Zentrum Berlin, Germany. Although EXED is a special-purpose instrument, its early construction made it available for users as a general-purpose diffractometer. In this respect, EXED became one of the rare examples, where the performance of a time-of-flight diffractometer at a continuous source can be characterized. In this paper, we report on the design and performance of EXED with an emphasis on the unique instrument capabilities. The latter comprise variable wavelength resolution and wavelength band, control of the incoming beam divergence, the possibility to change the angular positions of detectors and their distance to the sample, and use of event recording and offline histogramming. These features combined make EXED easily tunable to the requirements of a particular problem, from conventional diffraction to small angle neutron scattering. The instrument performance is demonstrated by several reference measurements and user experiments.

    Ever since the early days of homograft implantation in 1956, and the introduction into clinical practice by Ross and Barrat Boyes, homograft heart valves have proven to have many advantages. Its disadvantages became evident during long-term follow up. Factors, such as donor and recipient morbidity, tissue banking techniques, and the often complex surgical technique required to implant, are of great influence on the long term results. Because of European Directives, legally binding quality assurance regulations have been introduced in homograft banks. However, still not all processing methods have been scientifically sub-structured on their effects on the final product and its durability. The donor shortage has stimulated researchers and industries to develop and improve mechanical and biological valve substitutes such as the stentless bioprostheses. In general, candidates for homograft valve implantation include patients with: endocarditis, congenital defects and women who wish to become pregnant. For each category of patients different implantation techniques are required. The results of homograft banking and homograft transplantation in the German Heart Institute Berlin are satisfactory. Freedom of re-infection rate after homograft implantation is 91.9% +/- 3.6% after 15 years. Current developments show an increased interest in tissue engineered as well as in de- and re-cellularization of heart valve homografts. The advantages and disadvantages of the several processing techniques have not yet been proven in long term clinical results. For homograft bankers these developments pose as a challenge to join forces and to initiate cooperate projects aimed at scientific and organizational development.

    In many German cities and counties, sustainable mobility concepts that strengthen pedestrian and cyclist traffic are promoted. From the perspectives of urban development, traffic planning and public healthcare, a spatially differentiated analysis of traffic accident data is decisive. 1) The identification of spatial and temporal patterns of the distribution of accidents involving cyclists and pedestrians, 2) the identification of hotspots and exploration of possible underlying causes and 3) the critical discussion of benefits and challenges of the results and the derivation of conclusions. Spatio-temporal distributions of data from accident statistics in Berlin involving pedestrians and cyclists from 2011 to 2015 were analysed with geographic information systems (GIS). While the total number of accidents remains relatively stable for pedestrian and cyclist accidents, the spatial distribution analysis shows, however, that there are significant spatial clusters (hotspots) of traffic accidents with a strong concentration in the inner city area. In a critical discussion, the benefits of geographic concepts are identified, such as spatially explicit health data (in this case traffic accident data), the importance of the integration of other data sources for the evaluation of the health impact of areas (traffic accident statistics of the police), and the possibilities and limitations of spatial-temporal data analysis (spatial point-density analyses) for the derivation of decision-supported recommendations and for the evaluation of policy measures of health prevention and of health-relevant urban development.

    Gerhardt, Uta

    2014-01-01

    The article takes hedonism and revolution as a vantage point to discuss the Kommune 2, an experiment in collective living, the anti-authoritarian kindergardens for the under-fives, and, last but not least, a speech in 1968 that spurred the women's movement in Western Germany. The author's interest is on the materials documenting how the Berlin student movement saw psychoanalysis: One point was that the pleasure principle should replace the reality principle for the sake of humankind, another that the authoritarian character structure has its roots in the denial of sexuality. Kindergarden children supposedly need "de-individualized identification" to develop ego-strength, when boys and girls differ in their superego organization. An important accomplishment was a group analysis conducted without an analyst, an experiment that worked amazingly well in the Kommune 2. In all, these various experiments in emancipation, with psychoanalysis a guide to interpersonal understanding, may be deemed spectacular when their aftereffects on everyday life in Germany have been tremendous.

    In Germany, regular immigrants and their descendants have legal and financial access to health care equal to the general citizenry. Nonetheless, some of their health outcomes are comparatively unfavorable, and that is only partially explained by their lower socioeconomic status (SES). The aim of this study was to assess whether this disparity exists also for obstetric and perinatal outcomes. We compared obstetric and perinatal outcomes between immigrant women (first or second generation) and non-immigrant women, delivering at three maternity hospitals in Berlin, Germany, 2011-2012. Multivariable logistic regression analysis was used to assess immigrant status and other possible risk factors for the baby being delivered preterm, small for gestational age (SGA), or transferred to neonatal care. The final database retained 6702 women, of whom 53.1% were first- or second-generation immigrants. First-generation Turkish immigrant women had significantly lower odds of preterm birth (OR 0.37, P outcomes. This study provides strong evidence that health disparities for obstetric and perinatal health outcomes do not exist in immigrants relative to native Germans, but exist instead in women without post-secondary-level education compared to women with such education, regardless of ethnicity or migration history.

    Published diagnostic questionnaires for gambling disorder in German are either based on DSM-III criteria or focus on aspects other than life time prevalence. This study was designed to assess the usability of the DSM-IV criteria based Berlin Inventory of Gambling Behavior Screening tool in a clinical sample and adapt it to DSM-5 criteria. In a sample of 432 patients presenting for behavioral addiction assessment at the University Medical Center Mainz, we checked the screening tool's results against clinical diagnosis and compared a subsample of n=300 clinically diagnosed gambling disorder patients with a comparison group of n=132. The BIG-S produced a sensitivity of 99.7% and a specificity of 96.2%. The instrument's unidimensionality and the diagnostic improvements of DSM-5 criteria were verified by exploratory and confirmatory factor analysis as well as receiver operating characteristic analysis. The BIG-S is a reliable and valid screening tool for gambling disorder and demonstrated its concise and comprehensible operationalization of current DSM-5 criteria in a clinical setting.

    The first Transgenic Technology (TT) Meeting was organized in 1999 by Johannes Wilbertz, Karolinska Institute, Stockholm, Sweden as a regional meeting. The TT Meetings continued in this way, constantly gathering additional practitioners of transgenic methodologies until the breakthrough in 2005 when the 6th TT Meeting in Barcelona, Spain, hosted by Lluis Montoliu (Centro Nacional de Biotecnologia, Madrid, Spain), generated the momentum to establish the International Society for Transgenic Technologies (ISTT). Since 2006, the ISTT has continued to promote the TT Meetings and provide its membership with a forum to discuss best practices and new methods in the field. The TT2010 Meeting was held at the Max Delbrück Center for Molecular Medicine (Berlin, Germany). Participation at the TT2010 Meeting exceeded the registration capacity and set a new attendance record. Session topics included methods for the generation of rat and mouse models of human disease, fundamental and advanced topics in rodent embryonic stem cells, and the newest transgenic technologies. Short presentations from selected abstracts were of especial interest. Roundtable discussions on transgenic facility establishment and cryoarchiving of mouse lines were favorably received. Students, technical staff, and professors participated in numerous discussions and came away with practical methods and new ideas for research.

    The autopsy material of the institutes for forensic medicine in Berlin/GDR and Hamburg was analyzed retrospectively (period from 1961 till 1987; 70,000 autopsies) for fatalities caused by "humane killers" (n = 22) and stud guns (n = 12).-Epidemiological, criminological and morphological findings: The decreased were all men aged between 18 and 75 years (mean 48 years) except one 61 year-old paraplegic women who was killed by her husband with a humane killer. The great majority of cases consisted of suicides; two accidents at work were caused by stud guns. These unusual weapons are normally used by skilled people (i.e. butchers or constructional workers respectively). The fatal wounds were situated at the head, especially the forehead, seldom at the nape of the neck or in the mouth, or sometimes in the chest when using stud guns. Combined suicides (especially together with hanging) are not unusual. Survival periods (with or without acting capacity) can range between minutes or even months (after neurosurgical intervention).-The frequency of such unusual and overall rare cases did not raise during the investigation period.

    The origin and the development of scientific disciplines has been a topic of reflection for several decades. The few extensive case studies support the thesis that scientific disciplines are not monolithic structures but can be characterized by distinct social, organizational and scientific-technical practices. Nonetheless, most disciplinary histories of genetics confine themselves largely to an uncontested account of the content of the discipline or occasionally institutional factors. Little attention is paid to the large number of researchers who, by their joint efforts, ultimately shaped the discipline. We contribute to this aspect of disciplinary historiography by discussing the role of women researchers at the Institute for Heredity Research, founded in 1914 in Berlin under the directorship of Erwin Baur, and the sister of the John Innes Institute at Cambridge. This paper investigates how and why Baur built a highly successful research programme that relied on the efforts of his female staff, whose careers, notably Elisabeth Schiemann's, are also assessed in toto. These women undertook the necessary 'technoscience' and in some cases innovative work and helped increase the prestige of the institute and its director. Together they played a pivotal role in the establishment of genetics in Germany. Without them the discipline would have developed much more slowly and along a divergent path.

    Full Text Available Background: Obstructive sleep apnea (OSA is a fairly common problem with adverse health consequences. However, any screening questionnaire is not available in Hindi to screen sleep apnea. Materials and Methods: Subjects undergoing video-synchronized in laboratory attended polysomnography were requested to participate in this study. They were screened with the help of Hindi version of Berlin questionnaire (BQ. Outcome of the BQ was tested against the gold standard polysomnography. Descriptive statistics, sensitivity, specificity, positive predictive value (PPV, and negative predictive value (NPV of Hindi version were calculated. Results: 38 patients with polysomnography diagnosed OSA and 12 controls were included in this study. Average body mass index (BMI in the OSA group was 33.12 + 6.66 kg/m2 whereas in the control group BMI was 25.01 + 4.20 kg/m2. Average age in the OSA group was 48.9 + 10.2 years whereas the control group was older (56.9 + 12.1 years. Hindi version had sensitivity of 89% and specificity of 58%. PPV of the instrument was 0.87 whereas NPV was 0.63. Conclusion: Hindi version of BQ is a valid tool for screening the OSA irrespective of the literacy status of the subjects.

    2013-01-01

    Arthur Israel was associated with August Bier's University Surgical Clinic in Berlin from 1910 to 1933, in the end as the head of the downgraded (outpatient) clinic. After he was forced out of his Berlin post, Israel was department head in the Israelitisches Krankenhaus Hamburg until he emigrated to the U.S. in 1940, settling in New York. In 1960, he returned to Germany. Based on papers from Israel's estate, the article describes his life stations and his struggle to cope with his time at the Berlin university clinic. The focus is on a meeting in Berlin in 1961. His departure from the usual practice of heaping praise on the clinic and its former head marks the beginning of a never-published critique of conditions in the clinic. The ambivalence reflected in his evaluation is in stark contrast to the traditional cultivation of "Bier's School".

    Pust, M. [TECSOL GmbH, Friedeburg (Germany)

    2014-07-01

    Whoever plans to execute energy projects in today's world should be aware of the fact that the social framework conditions surrounding such projects have changed significantly. For the organization executing the project to merely adhere to the legally prescribed authorization procedure and leave it until the end of the planning procedure to inform those affected is often no longer sufficient for gaining public acceptance. Large parts of the population criticise the usual procedures because they have lost confidence in this kind of decision making, which offers them too little scope for co-determination. Thus for some years there has been a growing number of cases where citizens demand full public participation and early information on why the project in question is needed and what kinds of impact it will have. Lack of acceptance can lead to resistance, with negative effects on the project and the companies involved. TECSOL takes care of the communication management alongside energy projects, taking its bearings by the existing standards for voluntary early information of the public, as recommended by the VDI (Guideline 7001) and required by the legislature (PlVereinhG = Law for Improvement of Public Participation and Harmonisation of Plan Approval Procedures). The lecture outlines the societal challenges involved as well as the possibilities for dealing fairly with demands of the population in the context of energy projects. This is illustrated using the model case of the ''Etzel cultural landscape'' as a practical example, in which TECSOL played a prominent role on behalf of IVG Caverns GmbH. [German] Wer heute Energieprojekte umsetzen will, muss sich im Klaren darueber sein, dass sich die gesellschaftlichen Rahmenbedingungen stark veraendert haben.

    Threats and announcements of homicidal violence at schools may have massive consequences like evacuations, police searches, criminal investigations, or loss of the sense of security by students, teachers, and parents. However, there is a lack of systematic studies about that phenomenon. The present article would like to contribute to closing the research gap. It presents results about the frequency and structure of threats and announcements of homicidal violence in schools in Berlin. The study is based on an official dataset from school administration reports of violent acts in Berlin schools which has been studied within the Berlin Leaking-Projekt. The sample consists of 427 threats and announcements of homicidal violence between 1996 and 2007. The study is an exceptional analysis of the phenomenon: it presents crosscutting results about frequency and characteristics of threats and the threatening students as well as results of a longitudinal analysis about the development of threats and announcements. Results show a rate of 0,3 threats and announcements per 1 000 student and year. During the observation time span a steady increase of threats and announcements – year by year, influenced by imitation effects after school shootings – has been observed.

    Kuhne, Franziska; Struwe, Rainer

    2006-01-01

    The law for handling and control of dogs in Berlin of September 29, 2004 was enacted to prevent the risks for humans and animals when ever they have contact with dogs. "Dangerous dogs" are defined by this law. There are 10 breeds of dogs supposed to be dangerous due to specific characteristics of their breed ("listed breeds"). The dangerousness of a dog's breed is not identical with the dangerousness of an individual dog. The subject of this study is to examine the potential dangerousness of dog breeds and not the individual dangerousness of a dog. This study refers to statistics of incidents between dogs and humans in Berlin for the years 1998 to 2004. The population density of a breed is based on the dogs assessed for tax purposes in Berlin of January 1, 2005 and on the dog registrations maintained at veterinary hospitals. The fourfold-table-test was used to compare the quantity of the recorded incidents of two statistically independent dog breeds. Of the total population of 107,804 tax assessed dogs in Berlin in 2004, 0.9% was documented as dogs involved in incidents with humans. The incidents per year decreased in the "listed breeds"about 68% and in the "unlisted breeds" about 41% during the last 7 years in Berlin. Therefore, the probability (the odds ratio) of a breed to be conspicuous was analysed. The values for the calculation of this probability were the number of dogs of a breed having been involved in incidents compared to the population of this breed based on tax records. The comparison of the probability of a breed with another to be conspicuous was used to compile a cluster of breeds which had the same probability to be conspicuous in 2004. A cluster was assessed for dogs of the following breeds: Sheep dogs, Rottweiler, Doberman, Pitbull Terrier and American Staffordshire Terrier. A listing of breeds is not the right way to reduce the potential dangerousness of a dog, especially in the private domain of their owners. Most incidents with dogs occur in

    Real-time (RT) applications are in focus of recent GNSS research. International activities related to the RT data collection and distribution, as well as provision of specific RT data products (e.g., satellite orbits and clocks, station coordinates) are coordinated within the Real-Time Project of the International GNSS Service (IGS). Currently IGS provides real-time data from more than 100 globally distributed GNSS ground stations. This number, in parallel with the extension of various additional international real-time networks, is continuously increasing. In parallel to the rapid development of GNSS RT activities also innovative geophysical applications were pioneered by GNSS research groups and institutions, including GFZ. One prominent example is the use of GNSS components in early warning systems. GNSS measurements can be used there for the rapid detection and characterization of deformation fields, related to earthquakes, which induce Tsunamis. Such deformation data cannot be provided by seismometer measurements, but are important for the prediction of the tsunami wave propagation caused by earthquakes. The GNSS real-time group at GFZ is involved in several research projects related to geophysical RT GNSS applications, and also operates one of the RT analysis centers of the IGS. We introduce results of a real-time GNSS demonstration project, which was performed in 2012 at the new Berlin International Airport BER at Schönefeld, south-east of Berlin city center. The main goal of the project was the demonstration of the functionality of a complex RT-PPP server-client solution for dynamic applications which was developed within a joint research project of GFZ and the company Alberding GmbH. Compared to the standard PPP (clock & orbit) this solution uses additional information (ionosphere, uncalibrated phase delays UPD) to increase the positioning accuracy and to reduce the convergence time. The major challenges of the experiment were the stable operation of the

    Morale and job perception of staff in community mental health care may influence feasibility and quality of care, and some research has suggested particularly high burnout of staff in the community. The aims of this study were to: a) assess morale, i. e. team identity, job satisfaction and burnout, in psychiatrists, community psychiatric nurses and social workers in community mental health care in Berlin and London; b) compare findings between the groups and test whether personal characteristics, place of working and professional group predict morale; and c) explore what tasks, obstacles, skills, enjoyable and stressful aspects interviewees perceived as important in their jobs. In all, 189 mental health professionals (a minimum of 30 in each of the six groups) responded to a postal survey and reported activities per week using pre-formed categories. Perception of professional role was assessed on the Team Identity Scale, job satisfaction on the Minnesota Job Satisfaction Scale, and burnout on the Maslach Burnout Inventory. Seven simple open questions were used to elicit the main tasks, skills that staff did and did not feel competent in, aspects that they did and did not enjoy in their job, and obstacles and factors that caused pressure. Answers were subjected to content analysis using a posteriori formed categories. Weekly activities and morale varied between sites and professional groups. Some mean scores for groups in London exceeded the threshold for a burnout syndrome, and are particularly less favourable for social workers. Working in London predicted higher burnout, lower job satisfaction and lower team identity. Being a psychiatrist predicted higher team identity, whilst being a social worker was associated with higher burnout and lower job satisfaction. Male gender predicted lower burnout and higher team identity. However, professional group and site interacted in predicting burnout and job satisfaction. Psychiatrists in London had much more favourable

    Preterm infants are at higher risk for developmental problems. The aim of this study is to quantify the relation between birth weight and special educational needs. We analyzed data from the pre-school examinations of 134 313 children in Berlin aged 5 to 6 who were examined between 2007 and 2011. Special educational needs were diagnosed in 8058 children (6.0%), 4943 (61%) of whom had weighed 3000 g or more at birth. The percentage of children with special educational needs rose steadily with decreasing birth weight (2250-2499 g, 9.2%; 1250-1499 g, 21.1%; less than 750 g, 35.6%). Logistic regression analysis yielded odds ratios and 99% confidence intervals for special educational needs that ranged from 1.32 [1.17-1.47] for birth weight 2750-2999 g to 12.83 [7.48-22.03] for birth weight less than 750 g. Further risk factors were male sex (1.88 [1.75-2.03]), low social status (5.96 [5.21-6.82]), an immigrant background associated with poor German language skills in the family (1.63 [1.43-1.86]), and being raised by a single parent (1.21 [1.12-1.31]). On the other hand, nursery school and/or kindergarten enrollment for at least two years before entering school (0.82 [0.73-0.91]) and an immigrant background with good German skills in the family (0.39 [0.34-0.45]) were associated with lower rates of special educational needs. The risk of special educational needs increases already with moderately decreased birth weight. The most important factor other than birth weight is the family's social status. Although children of very low birth weight have a much higher rate of special educational needs than other children, they still make up only a small percentage of all children with special educational needs.

    The teaching of veterinary parasitology to the large number of students at the Freie Universität Berlin is mainly limited to conventional face-to-face lectures, supplemented by practical classes. Extensive parasite descriptions and diagnostic techniques are at the core of the practical classes, which are also intended to emphasise key biological and veterinary aspects covered in lectures. Further in-depth and specific learning is achieved within a detailed framework of elective courses, with defined learning outcomes for small groups of students, focusing on themes such as 'diagnosis and treatment of ectoparasites in companion animals' or 'zoonotic parasites'. Additionally, structured excursions are designed to offer experience through collaborative international investigations. Organ-based approaches are also an integral part of our veterinary parasitology teaching, done in collaboration with the clinical and para-clinical departments, either via face-to-face interactions or online. Wide-ranging themes, such as 'causes of colic in horses' or 'atopic dermatitis in dogs' are covered. Recently, diverse blended learning elements were introduced into the curriculum (e.g., QuerVet), which makes teaching and learning more flexible, in terms of time and space, and fosters self-directed learning and participation among the students. A new platform to provide online lectures for students, termed VET Talks, was launched in 2015 by the International Veterinary Student's Association (IVSA), and is as a publicly available educational support system for students. Provided free to veterinary students throughout the world, this platform offers students the opportunity to access lectures on interesting topics by outstanding speakers who are nominated by their students. Finally, continuing education (CE) opportunities are provided through specific Masters courses (Master of Equine Medicine, Master of Small Animal Sciences), classical seminars and recent webinars.

  9. Small rodents as paratenic or intermediate hosts of carnivore parasites in Berlin, Germany.

    Directory of Open Access Journals (Sweden)

    Jürgen Krücken

    Full Text Available Rodents are important intermediate and paratenic hosts for carnivore parasites, including the important zoonotic agents Toxoplasma, Echinococcus and Toxocara. Monitoring of such parasites in rodents can be used to detect increasing risks for human and veterinary public health. Rodents were trapped at four sites in Berlin, two near the city center, two at the periphery. PCRs were conducted to detect Coccidia (target ITS-1 and specifically Toxoplasma gondii (repetitive element in brain and ascarids (ITS-2 in muscle or brain tissue. During necropsies, metacestodes were collected and identified using ITS-2 and 12S rRNA PCRs. An ELISA to detect antibodies against Toxocara canis ES antigens was performed. Within the 257 examined rodents, the most frequently observed parasite was Frenkelia glareoli predominantly found in Myodes glareolus. T. gondii was only detected in 12 rodents and Microtus spp. (although strongly underrepresented had a significantly increased chance of being positive. Neither Echinococcus nor typical Taenia parasites of dogs and cats were found but Mesocestoides litteratus and Taenia martis metacestodes were identified which can cause severe peritoneal or ocular cysticercosis in dogs, primates and humans. Using PCR, the ascarids T. canis (n = 8, Toxocara cati (4 and Parascaris sp. (1 were detected predominantly in muscles. Seroprevalence of T. canis was 14.2% and ELISA was thus more sensitive than PCR to detect infection with this parasite. Non-parametric multidimensional scaling and cluster analysis revealed that parasite communities could be grouped into an urban and a peri-urban cluster with high frequency of ascarid-positive rodents in urban and high frequency of F. glareoli in peri-urban sites. Prevalence rates of parasites in rodents with potential impact for human or veterinary public health are considerable and the monitoring of transmission cycles of carnivore parasites in intermediate rodent hosts is recommended to

    Physical activity has been recommended based on beneficial effects described in HIV-infected patients. However, such guidelines do not take into account actual sport behaviours and general attitudes towards physical activity. To evaluate actual sport activity and attitudes towards sport in HIV-infected versus non-infected individuals we conducted an anonymous questionnaire investigating the prevalence, as well as possible changes, in sports engagement and the overall attitude to physical activity. A total of 283 patients of a general care facility specialized in the treatment of HIV/AIDS in Berlin, Germany, participated; 124 were HIV infected and 159 were non-infected, mostly men who have sex with men (MSM) (88%), with a median age of 35 years. The HIV-infected participants had a median CD4+ count of 554 cells/µL and 48.8% of them were using antiretroviral therapy (ART) at the time of survey. The proportion of patients actually performing physical activity was significantly lower (P = 0.028) within the HIV-infected group (61.3%) than within the non-infected group (74.2%). This difference remained significant after accounting for possible confounders such as age, gender, injecting drug use and sexual preferences. Previously reported sport activity prevalence was similar in both groups on leaving school. From our data we could not identify an association between the time of HIV diagnosis and changes in sports activity. In conclusion, fewer HIV-infected individuals report physical activity than non-infected individuals. Sociodemographic studies to evaluate potential differences in sports behaviour are required in order to inform exercise guidelines for HIV-infected patients.

    Zinc plays an important role for behavioral and mental function, maintaining the correct functions of intracellular signal transduction, cellular and trans-membrane transport, protein synthesis, and antioxidant system. We investigated both dietary zinc intake and plasma zinc levels and the correlation with depressive symptoms in a large sample of community-dwelling old. One thousand five hundred fourteen older people (aged 60-84 years, 772 women) from the Berlin Aging Study II were included. Zinc intake was assessed by the EPIC Food Frequency Questionnaire. Plasma zinc levels were assessed with atomic-absorption spectrophotometry. Depressive symptoms were assessed with the "Center for Epidemiological Studies Depression Scale" and the "Geriatric Depression Scale." Zinc deficiency in blood plasma was found in 18.7% of participants, and depressive symptoms in 15.7%. Participants with depressive symptoms had lower energy-adjusted zinc intake (median 11.1 vs 11.6 µmol/L; p = .048) and lower plasma zinc levels (median 12.2 vs12.3 mg/dL; p = .037). Even after adjustment for known predictors of depression, plasma zinc deficiency remained significantly associated with depressive symptoms (odds ratio: 1.490, 95% confidence interval: 1.027-2.164; p = .036). In the multiple logistic regression model stratified by sex, we found that plasma zinc deficiency was strongly associated with a higher risk for depressive symptoms in women (odds ratio: 1.739, 95% confidence interval: 1.068-2.833; p = .026). Plasma zinc deficiency was common in our old study population. An increase in dietary zinc and higher plasma zinc levels may reduce the risk of depressive symptoms. A screening for reduced dietary zinc intake or plasma zinc deficiency might be beneficial in older people at risk of depressive symptoms. © The Author 2016.

    Three macromolecular crystallography (MX) beamlines at the Helmholtz-Zentrum Berlin (HZB) are available for the regional, national and international structural biology user community. The state-of-the-art synchrotron beamlines for MX BL14.1, BL14.2 and BL14.3 are located within the low-β section of the BESSY II electron storage ring. All beamlines are fed from a superconducting 7 T wavelength-shifter insertion device. BL14.1 and BL14.2 are energy tunable in the range 5–16 keV, while BL14.3 is a fixed-energy side station operated at 13.8 keV. All three beamlines are equipped with CCD detectors. BL14.1 and BL14.2 are in regular user operation providing about 200 beam days per year and about 600 user shifts to approximately 50 research groups across Europe. BL14.3 has initially been used as a test facility and was brought into regular user mode operation during the year 2010. BL14.1 has recently been upgraded with a microdiffractometer including a mini-κ goniometer and an automated sample changer. Additional user facilities include office space adjacent to the beamlines, a sample preparation laboratory, a biology laboratory (safety level 1) and high-end computing resources. In this article the instrumentation of the beamlines is described, and a summary of the experimental possibilities of the beamlines and the provided ancillary equipment for the user community is given.

    Full Text Available Social participation of immigrants in district activities and local planning processes is given significance in Germany. It has become an important issue with the introduction of Neighborhood Management concept in the 1990s. This concept deals with districts which have a considerable percentage of low-income, unemployed, low-educated,immigrant population and social help beneficiaries. Immigrants are usually seen as the cause of the problems in those areas by the authorities since they are not integrated into the host societyand to the other immigrant groups. Since the 1990s, they have started to be seen as potential solution to the problems by means of an active social participation in their neighborhood. Desired level of social participation, however, has not been reached due to a number of reasons although there are a few immigrants who take part in social, cultural and planning activities in their district.The aim of this article is to outline the reasons of low participation rates, motivations of the participant immigrants and the forms of participation among Turkish and Arabic immigrantsin a neighborhood of Berlin, Moabit West, based on in-dept interviews made with both nonparticipant and participant immigrants and with some immigrant associations. The field research was carried out in June 2005, within the framework of the project ‘Immigrants in the City’. The reasons of low participation which were found as a result of this research study are language deficiency, different cultural understandings of participation, looking for concrete results of participatory actions and lack of information. The participant immigrants are motivated to solve the problems in the district and to change it, to increase integration of the immigrant youth into the society and of the immigrants, to the established society. Lastly, participant immigrants usually take part in street festivals and youth social work, and in immigrant associations instead of

  14. Seeking a compromise between pharmaceutical pollution and phosphorus load: Management strategies for Lake Tegel, Berlin.

    Lake Tegel (Berlin, Germany) is controlled by two main inflows: inflow #1 (River Havel) is heavily phosphorus-laden, whereas inflow #2 is an artificial confluence that includes discharge from a municipal wastewater treatment plant distinguished by high levels of phosphorus and pharmaceuticals. To reduce the phosphorus load on the lake, a phosphorus elimination plant (PEP) is situated at inflow #2. Moreover, the two inflows are short-circuited by a pipeline that transfers part of the inflow #1 water to the PEP and finally releases it into inflow #2. The pipeline and the PEP have contributed to a continuous reduction in the total phosphorus concentration of Lake Tegel in the past 25 years. We investigate the question of whether the existing lake pipeline can also be used to reduce the amount of pharmaceuticals in Lake Tegel originating from inflow #2 by dilution with water from River Havel, by diverting part of inflow #2 around the lake, or by a combination of both strategies. The circulation pattern of Lake Tegel is complicated by complex bathymetry and numerous islands and is therefore highly sensitive to winds. We tested seven different management scenarios by hydrodynamic modeling for a period of 16 years with the two-dimensional version of the Princeton Ocean Model (POM). None of the scenarios provided a strategy optimal for both pharmaceuticals and phosphorus. Nonetheless, compound regimes, such as alternating the pipe flow direction or adding another pipeline, allowed the most abundant pharmaceutical (carbamazepine) to be reduced while maintaining the current phosphorus level. This study demonstrates the ability of immediate lake regulation measures to maintain water quality. In the case of Lake Tegel, the pipeline can be fully effective with regard to pharmaceuticals only in combination with additional efforts such as advanced pharmaceutical treatment of wastewater and/or phosphorus reduction in the River Havel catchment.

  15. Prevalence of Trichomonas gallinae in northern goshawks from the Berlin area of northeastern Germany.

    Krone, Oliver; Altenkamp, Rainer; Kenntner, Norbert

    2005-04-01

    In recent years, the northern goshawk (Accipiter gentilis) has colonized suburban and urban areas in Berlin, Germany, and elsewhere in Europe. Because of the high proportion of feral pigeons (Columba livia f. domestica) in their diet, urban goshawks are suspected to have a high infection rate with Trichomonas gallinae. Therefore, from 1998 to 2001, we examined 269 nestlings from 90 nests for infection with T. gallinae by culture of swabs taken from the oropharynx and checked their oropharynx for the presence of caseous lesions indicative of trichomonosis. In 80% of the nest sites (n=90), at least one nestling was infected. The nestling infection rate with T. gallinae was 69.7% (n=33) in 1998, 73.0% (n=89) in 1999, 55.8% (n=77) in 2000, and 62.9% (n=70) in 2001. In total, 65.1% of the northern goshawk nestlings were culture positive for T. gallinae. Prevalence increased with the age of nestlings (chi2=12.4, n=269, df=5, P=0.03) and tended to increase with brood size (chi2=9.345, n=269, df=4, P=0.053). Caseous lesions were present in 12 nestlings (4.5%), but only 10 of these were culture positive for T. gallinae. Two nestlings (0.7%) had large caseous lesions (diameter>1 cm) characteristic of late-stage trichomonosis and died shortly after examination. It is suggested that the combination of a high prevalence of T. gallinae with a low rate of pathologicic changes is the result of an evolutionary-adapted parasite-host relationship.

    Although CKD is said to increase among older adults, epidemiologic data on kidney function in people ≥70 years of age are scarce. The Berlin Initiative Study (BIS) aims to fill this gap by evaluating the CKD burden in older adults. The BIS is a prospective population-based cohort study whose participants are members of Germany's biggest insurance company. This cross-sectional analysis (i) gives a detailed baseline characterization of the participants, (ii) analyses the representativeness of the cohort's disease profile, (iii) assesses GFR and albuminuria levels across age categories, (iv) associates cardiovascular risk factors with GFR as well as albuminuria and (v) compares means of GFR values according to different estimating equations with measured GFR. A total of 2069 participants (52.6% female, mean age 80.4 years) were enrolled: 26.1% were diabetic, 78.8% were on antihypertensive medication, 8.7% had experienced a stroke, 14% a myocardial infarction, 22.6% had cancer, 17.8% were anaemic and 26.5% were obese. The distribution of comorbidities in the BIS cohort was very similar to that in the insurance 'source population'. Creatinine and cystatin C as well as the albumin:creatinine ratio (ACR) increased with increasing age. After multivariate adjustments, reduced GFR and elevated ACR were associated with most cardiovascular risk factors. The prevalence of a GFR <60 mL/min/1.73 m 2 ranged from 38 to 62% depending on the estimation equation used. The BIS is a very well-characterized, representative cohort of older adults. Participants with an ACR ≥30 had significantly higher odds for most cardiovascular risk factors compared with an ACR <30 mg/g. Kidney function declined and ACR rose with increasing age.

    Sarcopenia affects more than 10% of older adults. Next to age-associated physiologic changes, diseases like diabetes or inflammatory, neurological, malignant and endocrine disorders may contribute to the development of sarcopenia. Likewise, polypharmacy, i.e., multiple drug use, is common among older adults. Although the two conditions frequently co-occur, the association of polypharmacy with sarcopenia has not yet been examined. We investigated the association of polypharmacy and sarcopenia in a large cohort of community-dwelling older adults (60-84 years). Thousand five hundred and two participants from the Berlin Aging Study II were included. Polypharmacy was defined as concurrent use of 5 or more drugs (prescription and nonprescription). Body composition was assessed with dual-energy X-ray absorptiometry, and appendicular lean mass (ALM) was calculated as sum of the four limbs' lean mass. Sarcopenia was defined as low ALM-to-body mass index (BMI)-ratio using validated sex-specific cutoffs. Mean age was 68.7 ± 3.7 years, 50.7% were female. The median (interquartile range) number of drugs was 2 (1-4); 21.1% of subjects reported regular use of ≥5 drugs. Subjects with polypharmacy were more often sarcopenic according to the applied ALM/BMI-cutoffs (16.3% vs 6.9%, p sarcopenia (odds ratio = 2.24, 95% confidence interval [CI] = 1.33-3.75). Polypharmacy is associated with clinically relevant sarcopenia, as assessed by a low ALM/BMI. © The Author 2017.

    This report demonstrates how carbon dioxide (CO(2)) may be a potent weapon in murder-suicide, where the death scene offers virtually no clues as to the lethal modality and the autopsy findings are nonspecific. Four bodies were discovered in an apartment in midsummer 2012 in Berlin, Germany. The bodies were those of a father (a 69-year-old business consultant), his wife (aged 26-years), and two sons (aged 3 and 6 years, respectively). The police found the wife and two sons lying in their beds and the husband in a supine position on the floor with a plastic bag over his head tied loosely around his neck with a rope. A 500 g single-use CO(2) cylinder was standing on the floor. The container was almost empty and according to the label had been sold as a CO(2)-fertilizer for aquarium plants. Two synthetic inhalation face masks and tubing were also found, which tested positive for the DNA of all four deceased family members. It is hypothesized that the husband placed an inhalation mask over the mouths and noses of his wife and children while they were sleeping. Inhalation of pure CO(2) ensured their rapid unconsciousness due to hypercapnia and severe anoxia. The rapid increase in CO(2) concentration would render a victim helpless, with no time to wake and defend themselves, or others. The proximate cause of death in all cases was attributed to CO(2) intoxication, based on the scene findings, the reconstructed sequence of events, the autopsy, and results of toxicological studies.

    The potential of emissions from urban vegetation combined with anthropogenic emissions to produce ozone and particulate matter has long been recognized. This potential increases with rising temperatures and may lead to severe problems with air quality in densely populated areas during heat waves. Here, we investigate how heat waves affect emissions of volatile organic compounds from urban/suburban vegetation and corresponding ground-level ozone and particulate matter. We use the Weather Research and Forecasting Model with atmospheric chemistry (WRF-Chem) with emissions of volatile organic compounds (VOCs) from vegetation simulated with MEGAN to quantify some of these feedbacks in Berlin, Germany, during the heat wave in 2006. The highest ozone concentration observed during that period was ∼200 μg/m 3 (∼101 ppb V ). The model simulations indicate that the contribution of biogenic VOC emissions to ozone formation is lower in June (9-11%) and August (6-9%) than in July (17-20%). On particular days within the analyzed heat wave period, this contribution increases up to 60%. The actual contribution is expected to be even higher as the model underestimates isoprene concentrations over urban forests and parks by 0.6-1.4 ppb v . Our study demonstrates that biogenic VOCs can considerably enhance air pollution during heat waves. We emphasize the dual role of vegetation for air quality and human health in cities during warm seasons, which is removal and lessening versus enhancement of air pollution. The results of our study suggest that reduction of anthropogenic sources of NOx, VOCs, and PM, for example, reduction of the motorized vehicle fleet, would have to accompany urban tree planting campaigns to make them really beneficial for urban dwellers.

    The balance of hemostasis and anticoagulation is a concern for patients dependent upon ventricular assist devices (VADs). Bleeding is a common complication with both short- and long-term use of these devices. A better understanding of the risk factors and etiologies of bleeding associated with these devices is needed and could improve the overall results. We sought to determine the relationship of mechanical circulatory assist device use with acquired von Willebrand disease (avWD) in children. Data were analyzed retrospectively via review of the medical record of 19 consecutive patients who were supported with the Berlin EXCOR VAD for greater than 24 hours. Laboratory testing for avWD was performed at the discretion of the clinical team, often in association with clinical bleeding. Of 19 pediatric patients, 10 (52.6%) had laboratory testing consistent with avWD. Median time to detection of avWD was 35 days postimplantation of device (range 0-310 days). Both minor mucosal bleeding and bleeding requiring intervention were highly prevalent in patients in whom avWD was identified (10/10 [100%] and 7/10 [70%]). The mean age of all patients was 3.3 years, but patients found to have avWD tended to be older (mean 5.3 years) and supported with larger volume VADs. This experience demonstrates a high prevalence of avWD following EXCOR implantation. Bleeding, older age, and larger VAD size may be associated with avWD. These results should stimulate critical evaluation of individualized anticoagulation regimens in pediatric VAD patients. © The Author(s) 2016.

    Solar energy will surely continue to be the most important renewable energy source. Since 1985, solar cell production has doubled every five years while the per unit price decreased continuously. This trend is expected to continue. Germany made important contributions both in the construction of new solar cell production plants and in the development of new PV materials and material combinations, as well as in technology and PV plant construction. The states of Thuringia and Saxony were significant contributors. In Thuringia, two solar cell production plants were constructed, while Saxon vacuum coating technology was used in nearly all new German production plants. This workshop presented the activities in Thuringia in Saxony. Contacts were to be established between partners from industry and research, joint projects were to be initiated, and society and politicians were to be informed on the success and new chances achieved. The workshop was held on the occasion of the termination of construction and the starting of experimental production of the ANTEC Solar GmbH factory at Rudisleben. [German] Im Mix der erneuerbaren Energien spielt die Solarenergie kuenftig wohl die wichtigste Rolle. Seit 1985 verdoppelt sich die Solarzellenproduktion in jeweils fuenf Jahren, gleichzeitig sank der Preis pro Leistungseinheit kontinuierlich. Dieser Trend wird weiter anhalten. Deutschland leistete in den letzten Jahren wichtige Beitraege zu dieser Entwicklung, sowohl beim Aufbau neuer Fertigungskapazitaeten fuer Solarzellen, als auch bei der Entwicklung neuer Photovoltaik-Materialien bzw. -Materialkombinationen und auf den Gebieten der Technologie und des Anlagenbaus. Der Anteil Thueringens und Sachsens an dieser positiven Entwicklung ist groesser als generell vermutet. In Thueringen entstanden zwei Unternehmen fuer die Solarzellenproduktion, der saechsische Vakuumbeschichtungs-Anlagenbau war am Aufbau fast aller neuen deutschen Fertigungsstaetten beteiligt.

    The energy transition in the heating sector is not a sure-fire success and it is too slow. This is alarming since the heating / cooling sector is responsible for more than half of the final energy demand. That the ''thermal change'' has accelerated hardly despite many efforts by politics, industry and research in recent years, is the reason for the scientists the FVEE institutes to examine the perspectives of renewable energy and the need to increase efficiency in the heating sector systematically. therefore FVEE-2015 Annual Meeting, is entitled ''Research for the thermal change''. The contributions of this conference proceedings present the latest research results and show ways to implement the heat change technically, economically and politically. They are dedicated to the drivers, but also the barriers of heat change. The authors report on innovative projects to provide buildings with heat from geothermal energy, biomass and solar thermal energy. Several contributions are dedicated to the application of efficient components, such as thermal insulation, thermal storage and heat pumps. [German] Die Energiewende im Waermesektor ist kein Selbstlaeufer und kommt zu langsam voran. Das ist alarmierend, da der Waerme-/Kaeltesektor fuer ueber die Haelfte des Endenergiebedarfs verantwortlich ist. Dass die ''Waermewende'' trotz vielerlei Bemuehungen von Politik, Industrie und Forschung in den letzten Jahren kaum Fahrt aufgenommen hat, ist Anlass fuer die Wissenschaftlerinnen und Wissenschaftler der FVEE-Institute, die Perspektiven der erneuerbaren Energien und der notwendigen Effizienzsteigerung im Waermesektor systematisch zu untersuchen. Die FVEE-Jahrestagung 2015 steht deshalb unter dem Leitthema ''Forschung fuer die Waermewende''. Die Beitraege dieses Tagungsbandes praesentieren aktuelle Forschungsergebnisse und zeigen Wege auf, um die Waermewende technisch, wirtschaftlich und politisch

    Within a joint project of the steel and automotive industry 17 steel sheet materials for automotive engineering in various delivery and forming conditions at temperatures of -40 C, 22 C and 100 C were investigated. In the course of 37 test series strain controlled fatigue curves to crack initiation and stress-strain-curves under monotonic and cyclic loading were determined. All experimental data, hysteresis loops and determined cyclic properties are available in a database. A correlation between the mechanical properties from tensile tests and the properties from strain controlled cyclic experiments seems to be possible.

    Reducing the noise level in the interior of vehicles is both a comfort necessity and a challenging technical task. Reliable identification of the accessories responsible for high or low engine-noise levels in the interior of cars classically requires costly, time-consuming, extensive measurement sessions.

    A tank made of stainless steel type X2CrNiMo17-12-2 for intermediate storage of salt brine for cheese production revealed significant pitting corrosion effects shortly after commissioning although comparable units have shown positive long-term behaviour. By means of electrochemical laboratory tests it could be demonstrated that the observed pitting corrosion was caused by the use of an oxidizing agent for desinfection purposes.

    Buckwheat whole plant can be used for the production of biogas. Due to its short growing period, buckwheat can be integrated very variable in crop rotations. For example, buckwheat can be grown as a second crop in the summer. After the harvest of winter wheat, which is used as whole plant silage, the sowing date is around mid-June. The ingredients of buckwheat expect a good fermentability with corresponding biogas production. [German] Buchweizen-Ganzpflanzen koennen fuer die Erzeugung von Biogas genutzt werden.

First ideas about standard demands, technical solutions and multi-functional design showed that the project had to be handled in such a flexible way that temperature controlling (for the transportation of deep-frozen goods, temperature-controlled DANZAS-warehouses and all future temperature-controlled transportation) and the monitoring of security-relevant transportation can be integrated in one and the same project.

    Bleeding and thrombotic events remain a significant cause of morbidity in pediatric patients supported with ventricular assist devices (VADs). The objective of this study is to identify the association between markers of anticoagulation and bleeding and thrombosis events during Berlin Heart ExCor support. A retrospective, single-center analysis of 9 patients supported with the Berlin Heart ExCor was performed. Inflammatory and anticoagulation parameters including C-reactive protein, fibrinogen, partial thromboplastin time (PTT), and platelet count were measured at 48 and 24 h before and after bleeding or thrombosis events. Patients served as their own controls, and the same parameters were measured during a control period where subjects did not experience either event. All patients received the anticoagulation regimen proposed by Berlin Heart. A total of 31 bleeding or thrombotic events were identified and matched to 18 control events. Patient with predominantly thrombotic events tended to weigh less than those with bleeding events (Δ7.7 kg, p < 0.001). PTT levels were higher before and after bleeding (Δ17.36, p = 0.002) and thrombosis (Δ8.75, p < 0.001) events relative to control. Heparin dose decreased after a thrombosis event (Δ-5.67, p = 0.097), and this decrease was significantly different from control (p = 0.032). Non-collinearity between heparin dose and PTT should prompt further inflammatory and hematological investigation. In addition, heavier patients were more prone to bleeding complications. The role of inflammation in the development of thrombus or hemorrhages in the pediatric VAD population needs to be studied further.

    Emerging organic contaminants (EOCs) are frequently detected in urban surface water and the adjacent groundwater and are therefore an increasing problem for potable water quality. River bank filtration (RBF) is a beneficial pretreatment step to improve surface water quality for potable use. Removal is mainly caused by microbial degradation of micropollutants, while sorption retards the transport. The quantification of biodegradation and adsorption parameters for EOCs at field scale is still scarce. In this study, the fate and behavior of a range of organic compounds during RBF were investigated using a two dimensional numerical flow- and transport model. The data base used emanated from a project conducted in Berlin, Germany (NASRI: Natural and Artificial Systems for Recharge and Infiltration). Oxygen isotope signatures and hydraulic head data were used for model calibration. Afterwards, twelve organic micropollutants were simulated with a reactive transport model. Three compounds (primidone, EDTA, and AMDOPH) showed conservative behavior (no biodegradation or sorption). For the nine remaining compounds (1.5 NDSA, AOX, AOI, MTBE, carbamazepine, clindamycin, phenazone, diclofenac and sulfamethoxazole), degradation and/or sorption was observed. 1.5 NDSA and AOX were not sorbed, but slightly degraded with model results for λ=2.25e(-3) 1/d and 2.4e(-3) 1/d. For AOI a λ=0.0106 1/d and R=1 were identified. MTBE could be characterized well assuming R=1 and a low 1st order degradation rate constant (λ=0.0085 1/d). Carbamazepine degraded with a half life time of about 66 days after a threshold value of 0.2-0.3 μg/L was exceeded and retarded slightly (R=1.7). Breakthrough curves of clindamycin, phenazone, diclofenac and sulfamethoxazole could be fitted less well, probably due to the dependency of degradation on temperature and redox conditions, which are highly transient at the RBF site. Conditions range from oxic to anoxic (up to iron-reducing), with the oxic and

    The frequency and successful use of pediatric ventricular assist devices (VADs) as a bridge to cardiac transplantation have been steadily increasing since 2003, but the experience in patients with complex congenital heart disease has not been well described. Using a large prospectively collected dataset of children supported with the Berlin Heart EXCOR VAD, we have reviewed the experience in children with single ventricular anatomy or physiology (SV), and compared the results with those supported with biventricular circulation (BV) over the same time period. The EXCOR Investigational Device Exemption study database was retrospectively reviewed. VAD implants under the primary cohort and compassionate use cohort between May 2007 and December 2011 were included in this review. Twenty-six of 281 patients supported with a VAD were SV. The most common diagnosis was hypoplastic left heart syndrome (15 of 26). Nine patients were supported after neonatal palliative surgery (Blalock-Taussig shunt or Sano), 12 after a superior cavopulmonary connection (SCPC), and 5 after total cavopulmonary connection (TCPC). Two patients received biventricular assist devices, 1 after stage I surgery and 1 after stage II. SV patients were supported for a median time of 10.5 days (range, 1-363 days) versus 39 days (range, 0-435 days) for BV (P = .01). The ability to be bridged to transplant or recovery in SV patients is lower than for BV patients (11 of 26 [42.3%] vs 185 of 255 [72.5%]; P = .001). Three of 5 patients with TCPC were successfully bridged to transplant and were supported with 1 VAD. Seven of 12 patients with SCPC were bridged to transplant, and only 1 of 9 patients supported after a stage I procedure survived. The EXCOR Pediatric VAD can provide a bridge to transplant for children with SV anatomy or physiology, albeit less successfully than in children with BV. In this small series, results are better in patients with SCPC and TCPC. VAD support for patients with shunted sources

    The drinking water production of a drinking water treatment plant in Berlin is affected by ambient contaminated groundwater. The three organic compounds para-toluenesulfonamide (p-TSA), ortho-toluenesulfonamide (o-TSA) and benzenesulfonamide (BSA) were identified in the catchment area of this plant. The groundwater pollution is a result of former sewage farm irrigation in the area, operating for almost 70 years until the 1980s. The distribution of the sulfonamides in the anoxic groundwater was investigated, and a large number of observation and production wells were sampled for this purpose. The contaminant plume is 25 m * 3000 m * 2000 m (depth, length, width) in size. The high concentrations of p-TSA, o-TSA and BSA in the groundwater show that the sulfonamides persist over decades in an anoxic aquifer environment. Groundwater quality assessment revealed that elevated concentrations of the analytes can be expected in the abstraction well galleries in the future. Therefore, sulfonamides should periodically be monitored in the drinking water (maximum allowed concentration of 0.30 µg/L of p-TSA and for o-TSA and BSA, a limit of 0.10 µg/L for unknown substances applies). Because of the widespread application and the persistence of the sulfonamides under anoxic conditions, our local investigations suggest that the substances may generally be present in groundwater under the influence of sewage irrigation. Incubation experiments were conducted under in situ hydrostatic pressure to study the behaviour of these trace organic compounds under different redox conditions (oxic and anoxic). Groundwater sampling equipment was either sterilised or not sterilised in order to distinguish between microbiological processes occurring in the aquifer and those representing sampling and storage artefacts (incubation experiments). Results showed that the addition of oxygen to the anoxic groundwater facilitates p-TSA and o-TSA degradation. Hence, while the substances are persistent

    Full Text Available Bacillus thuringiensis Berliner based biopesticides have been successfully used world over for the control of agricultural pests and vectors of human diseases. Currently there are more than 200 B. thuringiensis strains with differing insecticidal activities are available as biocontrol agents and for developing transgenic plants. However, two major disadvantages are the development of insect resistance and high target specificity (narrow host range. Globally there is a continuous search for new B. thuringiensis strains with novel insecticidal activities. The present study aims to study the environmental distribution of B. thuringiensis and their toxic potential against insect pests. Soil and grain samples were collected from different environments and were processed by a modified acetate selection method. Initially B. thuringiensis isolates were screened on the basis of colony morphology and phase contrast microscopy for the presence of parasporal crystal inclusions. The population dynamics showed that B. thuringiensis is abundant in sericulture environment compared to other niches. Relative abundance of B. thuringiensis strains in sericulture environment shows the persistent association of B. thuringiensis with Bombyx mori (silk worm as insect pathogen. The protein profiles of the selected strains were studied by SDS-PAGE. The protein profiles of majority of B. thuringiensis isolates from grain storage facilities predominantly showing the 130 kDa and 68 kDa proteins, which is characteristics of lepidopteran active B. thuringiensis. However, one isolate BTRX-4 has 80-85 kDa protein, which is novel in that, this strain also exhibits antilepidopteran activity, which is normally presented by B. thuringiensis strains having 130 kDa and 68 kDa proteins. The protein profile of B. thuringiensis isolates from sericulture environment shows two different protein profiles. B. thuringiensis isolates BTRX-16 to BTRX-22 predominantly show 130 kDa protein

    Enormous progress has been made in paediatric heart transplantation since the first unsuccessful effort by Kantrowitz in 1967. Early reports of children undergoing heart transplantation showed alarmingly high perioperative mortality rates of 25-60%, with the diagnosis of congenital heart disease (CHD) representing a particularly high-risk subset compared with cardiomyopathy. Many of these early failures were related to poor patient selection, suboptimal immunosuppression and technical problems. We learned a great deal from these earlier difficulties. Presently, with more refined techniques, better-defined patient selection criteria, excellent graft rejection monitoring and optimal immunosuppression, the ISHLT 2011 registry reported a 10-year survival rate of 60% for patients transplanted for end-stage CHD and >70% for those transplanted for cardiomyopathy. The technical dilemmas in complex CHD were overcome by surgical ingenuity and creativity, innovative solutions and careful surgical planning, adapting the complex recipient anatomy to the normal donor anatomy. The miniaturized Berlin Heart pulsatile ventricular assist devices in children as a bridge to transplantation have revolutionized treatment and become a significant contribution in heart-failure therapy. The intramyocardial electrogram and echocardiographic strain rate imaging have been employed as non-invasive techniques of rejection monitoring. Immunosuppressive drugs have a major impact on the development and progression of cardiac allograft vasculopathy, the main cause of cardiac allograft loss and a leading cause of mortality after the first year post-transplantation. The questions of whether a transplanted heart in a newborn grows to adult size along with the child and whether the dimensional cardiac growth allows adequate function over time have been largely answered in our previous investigations. As more transplanted children reach adulthood, concerns about their life expectancy when they have

    Historically, German environmental policy has always been based on order policy, so Germany is lagging behind, as compared with Denmark or England, in accumulating initial experience with emissions trading as a clean air policy instrument.

The project called SET UP is presented, results are analyzed, and conclusions are drawn. [German] Da die deutsche Umweltpolitik traditionell ordnungspolitisch gepraegt ist, liegen bisher - im Unterschied zu anderen EU-Mitgliedstaaten wie Daenemark oder England - kaum praktische Erfahrungen mit dem marktwirtschaftlichen Instrument Emissionsrechthandel vor.

    Principal Correlation Pattern Analysis (PCPA) maps the local circulation, temperature and precipitation anomalies in the northern hemisphere in monthly resolution and permits an interpretation of their causes. Calculations are made for the El Nino phenomenon, NAO, and the quasi-11-year cycle of solar radiation variation. Especially the El Nino calculations show the efficiency of PCPA. [German] Mit Hilfe der Principal Correlation Pattern Analysis (PCPA) koennen die von verschiedenen Klimaantrieben erzeugten lokalen Zirkulations-, Temperatur- und Niederschlagsanomalien auf der Nordhemisphaere in monatlicher Aufloesung dargestellt und ursaechlich interpretiert werden. Diese Rechnungen wurden fuer das El Nino Phaenomen, die NAO und den quasi 11-jaehrigen Zyklus der solaren Strahlungsschwankungen durchgefuehrt. Insbesondere die Untersuchungen zu Wirkungen von El Nino auf Europa zeigen, dass die PCPA die Kopplungen eines Prozesses mit dem Klimasystem sehr genau beschreibt und somit die Voraussetzungen schafft, die Wirkungen dieses Klimaantriebs zu modellieren und ihn zur Vorhersage zu nutzen. Erste einfache Vorhersageexperimente fuer das europaeische Klima bestaetigen diese Aussage. (orig.)

    Flashbulb memories for the fall of the Berlin Wall were examined among 103 East and West Germans who considered the event as either highly positive or highly negative. Participants in the positive group rated their memories higher on measures of reliving and sensory imagery, whereas memory for fa......, rehearsal and the centrality of the memory to the person's identity and life story correlated positively with memory qualities. The results suggest that positive versus negative emotions have different effects on the processing and long-term retention of flashbulb memories....

    To describe the structural and functional changes that occur in traumatic Berlin's edema involving the macula through assessment with multifocal electroretinogram (mfERG), microperimetry, fundus photography, and spectral-domain optical coherence tomography (SD-OCT). Retrospective case series of five eyes from four patients with macular traumatic Berlin's edema. Patients underwent baseline mfERG (three eyes), MP1 microperimetry (three eyes), fundus photography (five eyes), and SD-OCT (five eyes). All eyes with Berlin's edema showed abnormal findings on baseline SD-OCT, including disruption and fragmentation of the inner segment/ outer segment layer. In two patients with unilateral blunt ocular trauma who underwent mfERG, there was complete loss of the foveal peak in affected eyes. All three eyes that underwent microperimetry showed depressed retinal sensitivity in the area of Berlin's edema. SD-OCT, microperimetry, and mfERG can be used to help diagnose, stratify traumatic severity, and follow structural and functional progression over time in patients with Berlin's edema.

    Lead has always been an important metal in plain bearing technology. Completely lead-free solutions for high-end engine applications are still not considered to be technically achievable. Therefore, the European End of Life Directive (2000/53/EC), which took effect on 1 July 2003, lists copper-based lead/bronze bearings as an exception. The bearing group of Federal-Mogul has now announced its exit from the lead industry and addresses the issue layer by layer. A recently introduced adaptive bearing offers a lead-free overplate for high-performance internal combustion engine applications. This new bearing changes its technical characteristics during the running-in phase. (orig.) [German] Blei war schon immer eine wichtige Komponente in der Gleitlagertechnik. Bis heute gelten vollstaendig bleifreie Loesungen fuer hochbelastete Gleitlager als technisch nicht machbar. Deshalb nennt die europaeische Altautoverordnung (2000/53/EG), die seit dem 1. Juli 2003 in Kraft ist, als Ausnahme die kupferbasierten Bleibronzelager. Die Gleitlagergruppe von Federal-Mogul hat jetzt ihren Rueckzug aus der Verarbeitung von Blei angekuendigt und geht das Thema Schicht fuer Schicht an.

    The report presents a summary of the project of the above title (EFAS project). While earlier projects focused on the technical side, EFAS is the first to present a systematic analysis, presentation and evaluation of the parameters influencing driving support systems. With the aid of a systemic analysis, the key influencing factors are defined and analyzed, and three scenarios are developed which take account of user-oriented, organizational, operational, technical, infrastructural and legal aspects. The scenarios are evaluated with the aid of driving and traffic simulations in the fields of humans, organization and technology, and actions are recommended on this basis for driving support systems in cargo transport. [German] Der Bericht fasst die Ergebnisse des Projektes ''Einsatzszenarien fuer Fahrerassistenzsysteme im Gueterverkehr'' (EFAS) zusammen. Bisher wurde die Thematik Fahrerassistenzsysteme hauptsaechlich auf der Seite der Fahrzeugtechnik vorangetrieben. Das Projekt EFAS stellt nun zum ersten Mal eine umfassende Analyse, Darstellung und Bewertung dar. Mit Hilfe einer systemischen Analyse werden die wesentlichen Einflussfaktoren fuer die Einbindung von Fahrerassistenzsystemen in das Gesamtsystem ''Verkehr'' bestimmt und untersucht. Hieraus werden drei Einsatzszenarien entwickelt, die nutzerbezogene, organisatorische, betriebliche, fahrzeugtechnische, infrastukturelle und rechtliche Aspekte zu Zukunftsbildern zusammenfuegen. Die Szenarien werden mit Hilfe von Fahr- und Verkehrssimulationen in den Bereichen Mensch, Organisation und Technik bewertet. Aus den Ergebnissen werden konkrete Handlungsempfehlungen fuer den Einsatz von Fahrerassistenzsystemen im Strassengueterverkehr abgeleitet. (orig.)

    Mouse lines long-term selected for high fatness offer the possibility to identify individual genes involved in the development of obesity. The Berlin Fat Mouse (BFM) line has been selected for low protein content and afterward for high fatness. Three Berlin Fat Mouse Inbred (BFMI) lines, which are derivates of the selection line BFM and an unselected control line (C57BL/6; B6) were systematically phenotyped between 3 and 20 wk. The body weights and body compositions were measured on a weekly basis. We demonstrated that the BFMI lines dispose of more body weight, body fat mass, and body lean mass than the control line B6 because of a better feed efficiency in these lines. In contrast to other growth-selected mouse lines, the BFMI lines exhibited a general increase in body fat mass but only a marginal increase in body lean mass. The three BFMI lines also showed line- and sex-specific patterns and varied in their response to high-fat diet. The phenotypic differences between the BFMI lines can be traced back to different sets of fixed alleles contributing to fat accumulation and diet-induced obesity. Our results demonstrate that the genetically related BFMI lines are novel models to study the genetic as well as the nutritional aspects of obesity.

    Urban emissions of particulate matter and precursors of ozone are very important in relation to the EU-council directives and national pollution abatement strategies. Knowledge about the contribution of anthropogenic urban sources and about long range transport of polluted air to local concentrations is needed for any reduction strategy. Thus, within the German Atmospheric Research Program AFO2000 a project has been started to investigate the formation and transport of PM10/PM2.5 in the greater Berlin area by sampling and analysing PM, using LIDAR as well as physico-chemical measurements to determine density, partical size distribution and chemical composition of the aerosol. Participants are: Freie Universität Berlin, Institute for Meteorology BTU Cottbus, Air Chemistry Department Elight Laser Systems GmbH Freie Universität Berlin, Physics Department Environmental Administration, Berlin Government with an additional PM campaign Measurements at central Berlin monitoring stations exceed standard PM10 tresholds. Therefore, it is important to get a better knowledge about PM sources within and outside the city. Long term applications of the chemical transport model with an aerosol-module REM3/Calgrid is used to explain transport, formation and deposition processes. Backward and forward trajectories are used to determine source/receptor relationships between the observations and European wide emission maps for ozone, precursors and PM10 and PM2,5 by correlation between observed primary aerosols in Berlin and possible sources. The measurements obtained within the project are also used to validate REM3/Calgrid with special respect to SO4, NO3, NH4 and ozone precursors.

  13. Music and politics after the Holocaust: Menuhin’s Berlin concerts of 1947 and their aftermath

    Full Text Available Between September 27 and October 3, 1947, Yehudi Menuhin gave six performances in Berlin, two of them together with Wilhelm Furtwängler, who had just been cleared by the denazification tribunals in Austria and Germany. Because of the German audience and the Furtwängler collaboration, these concerts led to a scandal in the Jewish community and the Displaced Persons camp in Germany as well as Jewish communities abroad. I turn first to the historical background of these performances, specifically the position of Menuhin and Furtwängler toward each other and their roles in postwar Germany. I will then chronicle the events of September and October 1947 through the lenses of Abraham S. Hyman, legal consultant to the American Advisers on Jewish Affairs in Germany, and Yehudi Menuhin and his biographers, to reveal the complexity of the events. Lastly, I will scrutinize the reception of the concerts to shed light on the reasons for and impact of the scandal. I argue that these concerts were mishandled in their organization and aims, in that politics played too large a role in the events during a time when the Jewish people suffered severe trauma in the aftermath of the Holocaust.

    Entre el 27 de septiembre y el 3 de octubre del 1947, Yehudi Menuhin ofreció seis conciertos en Berlín, dos de ellos con Wilhelm Furtwängler, quien acababa de ser declarado inocente por los tribunales de “desnazificación” en Austria y Alemania. Debido a que el público era alemán y a la participación de Furtwängler, estos conciertos provocaron un fuerte escándalo entre la comunidad judía y la población desplazada de los campos en Alemania, así como entre las comunidades judías en el extranjero. Mi investigación se centra, primero, en el contexto histórico de estos conciertos y, concretamente, la posición de Menuhin y Furtwängler hacia el uno al otro, así como sus respectivos papeles en la Alemania de la postguerra. Posteriormente ofrezco una relaci

    As a prerequisite for MR-guidance of interventional procedures, instruments have to be well depicted in the MR image without obscuring or distorting the underlying anatomy. For non-vascular interventions the imaging speed has to be in the range of seconds while control of vascular interventions requires real time imaging speed. The imaging contrast has to be maintained as well as a high spatial resolution. Furthermore, sufficient patient access has to be provided by the MR scanner. Neither an ideal magnet nor the optimal single sequence are available to fulfill the above-mentioned criteria. The type of sequence - gradient echo versus spin echo - together with changing of the echo time and phase encording direction will ensure an appropriate size of the artifact and thereby of the appearance of the instrument in the MR image. The feasibility of non-vascular MR-guided interventions has been proved at field strengths ranging from 0.064 T to 1.5 T. Bone biopsies, soft tissue biopsies, drainages, and control of interstitial thermo- and cryotherapy have been reported. For vascular interventions, different real time MR strategies are currently under investigation. The development of dedicated catheters and guide wires has enabled MR-guided dilatations, stenting, placement of vena cava filters, and TIPS procedures. Considering the fast progress being made in this field, there can be no question that interventional MRI will become a well-accepted clinical tool offering potential advantages such as excellent soft tissue contrast, multiplanar imaging, flow measurements, high resolution imaging of vessel walls, and lack of ionizing radiation.

Nach den Ergebnissen der Literatur sind Schnittbildverfahren dem Roentgenskelettstatus signifikant ueberlegen, wobei die Ganzkoerper-MRT fuer den Nachweis insbesondere eines diffusen Knochenmarkbefalls signifikant besser ist als die Ganzkoerper-CT. Praktisch jeder osteodestruktive Herd ist in der MRT sichtbar. Allerdings ist fuer die Beurteilung der Osteodestruktion selbst wiederum eine CT erforderlich. Die Sensitivitaeten von PET/CT und MRT sind vergleichbar. Wie bereits in einigen Zentren insbesondere in Deutschland umgesetzt, sollten bei Verfuegbarkeit das Ganzkoerper-MRT und das Ganzkoerper-CT den konventionellen Roentgenskelettstatus ersetzen.

    Arbeit beschaeftigt sich mit einem drei- zu zweiphasigen Matrixumrichter zur Speisung von kontaktlosen Energieuebertragungssystemen. Aufbauend auf einer Darlegung relevanter Untersuchungen zur Thematik werden zunaechst moegliche Resonanzanordnungen fuer kontaktlose Energieuebertragungssysteme untersucht. Die Betrachtung wichtiger elektrischer Parameter zeigt neben den Unterschieden der einzelnen Anordnungen auch, dass fuer eine auf den speisenden Umrichter fokussierte Untersuchung eine einfache Modellierung der drei untersuchten Resonanzanordnungen mit Hilfe eines Reihenschwingkreises moeglich ist. Als Konsequenz ergibt sich die Schlussfolgerung, dass sich die erzielten Ergebnisse auch fuer den Matrixumrichter mit anderen serienresonanten Lasten anwenden lassen. Der zweite Teil der Arbeit ist der Untersuchung des Matrixumrichters gewidmet. Basierend auf einer theoretischen Beschreibung wird die Kombination von hochfrequenten Steuerverfahren - wie z.B. der Blocktaktung - und niederfrequenten Pulsmustern zur Stellung des Oberschwingungsgehalts der Netzstroeme vorgestellt. Die Aehnlichkeit des Umrichters zu einem konventionellen Wechselrichter in H-Brueckenschaltung ermoeglicht anschliessend eine Betrachtung der Kommutierung und die Ableitung notwendiger Schaltzustaende. Diese sind dadurch gekennzeichnet, dass zu jedem Zeitpunkt genau eine bidirektionale Verbindung vom Eingangssystem zu jeder Ausgangsphase besteht. Die Funktionsweise der Kommutierung wie auch des gesamten Umrichters wird in einem ersten Schritt simulativ belegt. Dabei wird auch das dynamische Schaltverhalten der Leistungshalbleiter beruecksichtigt. Anschliessend werden an einem Laboraufbau aufgenommene Messergebnisse vorgestellt und mit den theoretischen Ergebnissen verglichen. Der Laboraufbau besteht aus dem Leistungsteil des Matrixumrichters mit Eingangsfiltern und modularen Gate-Treibern, einem DSP/FPGA-Steuerungssystem und einem kontaktlosen Energieuebertragungssystem mit sekundaerseitigem Gleichrichter

Infolge des Todes von D. L. G. Karsten im Jahre 1810 erhielt der Leipziger Physiker und Mineraloge C. S. Weiss den Lehrstuhl für Mineralogie, den er bis zu seinem Tode 1856 innehatte. Weiss entwickelte die Lehre Werners, die die Mineralogie einschließlich Geologie umfasste, in kristallographischer Hinsicht weiter, während sich später neben ihm zwei seiner Schüler anderen Teilgebieten der Mineralogie annahmen, G. Rose der speziellen Mineralogie und E. Beyrich der geologischen Paläontologie. Der Ausbau der Sammlungen durch eigene Aufsammlungen, Schenkungen und Käufe konnte in starkem Maße fortgesetzt werden, auch zunehmend in paläontologischer Hinsicht, sodass das Mineralogische Museum für das ganze Spektrum der Lehre gut bestückt war.

    The following paper presents a research project that is planned as a cooperation of the Geological Institute, University of Wuerzburg and the Bavarian Center of Applied Energy Research. In this project the potentials for underground thermal energy storage will be investigated in the region of Mainfranken, Northern Bavaria (Main = the river `Main`, Franken = Franconia). All aspects of underground storage will be studied with respect to the specific geographical and geological situation of the area. The study will provide a detailed map of possible storage sites, from which several case studies and at least one demonstration projects will result. (orig.)

    Subject of the current project ''3605S04477 - Entwicklung einer ''Job-Exposure-Matrix'' fuer Tieraerzte zur Abschaetzung der Exposition an ionisierender Strahlung bei der Diagnose mit Hilfe von Roentgengeraeten in der tieraerztlichen Praxis'' is the analysis of the radiation exposure of medical staff due to diagnostic x-ray examinations in veterinary medicine. In detail the radiation exposure of the medical staff will be first measured and next will be analysed and transformed into a data structure, which allows an easy estimation of the radiation exposure of the medical staff due to the future execution of diagnostic x-ray examination. The measurements, this data structure (called ''Job-Exposure-Matrix'') is based on, will be taken primarily during examinations performed at two veterinary clinics of the ''Freie Universitaet Berlin (FU Berlin)'', which are linked to the project. In addition some further measurements are taken at four veterinary clinics in Germany. Finally, for some examinations measurements are performed using phantoms set up of dead animals. Due to the shielding of the x-ray protective clothing and the resulting very low values the doses are measured in front of the protective clothing. Primarily, electronic personal dosemeters are used, complemented by thermoluminescence dosemeters and an ionisation radiation chamber. The measurement and the related analysis show, that the exposure of the medical staff due to the scattered Roentgen beam during a single x-ray examination is low. However, a high frequency of examinations during a year may result in no more marginal exposure which in addition might exceed the relevant dose limits. Thus, the measurements also emphasize the importance of radiation shielding even in case of low exposure due to a single x-ray examination. The compilation of the measured data in the data structure allows an easy estimation of the radiation

    The contribution describes the production of silicon wafers in all stages: Melting and crystallisation, production of wafers and columns, careful cleaning and quality control of every single silicon wafer. The initial material is pure silicon as used in the production of electronic chips. Bayer Solar GmbH are producers of monocrystalline and multicrystalline silicon wafers. By the end of 1999, their two works at Uerdingen and Freiberg had a total capacity of about 36 MWp, i.e. about 25% of the world demand. [German] Im Beitrag wird der Werdegang vom Silicium bis zum photovoltaischen System kurz dargestellt, wobei, bedingt durch eine teilweise Arbeitsteilung, die Si-Wafer und Zellen als Zwischenstufen auftreten. Die Bayer Solar GmbH hat sich dabei bis heute auf die Herstellung von mono- und multikristallinen Siliciumscheiben konzentriert, wobei Werke in Uerdingen und Freiberg Ende 1999 eine Gesamtkapazitaet von etwa 36 MWp bereit halten, was ca. 25% des weltweiten Bedarfs entspricht. Der Weg vom Silicium zum Wafer umfasst das Schmelzen und Kristallisieren, die Saeulen- und Scheibenherstellung, eine sorgfaeltige Scheibenreinigung und anschliessende Qualitaetskontrolle jeder einzelnen Siliciumscheibe. Ausgangsmaterial ist ein hochreines Silicium, wie es aehnlich auch fuer die Chipherstellung in der Elektronik verwendet wird. (orig.)

    Processes in which a heat pump cycle is driven by thermal energy may be defined as heat transformation processes. The technical realization of this type of processes in general is based on sorption techniques. Depending on the temperature level of the utilized heat these technologies may be used for either cooling or heating of buildings. The paper presents state-of-the-art technologies and new developments. It comprises solar cooling of buildings, utilization of environmental energy sources (earth, air) by thermal driven heat pumps and seasonal storage of solar thermal energy by means of sorption processes.

    There are various financing and organisation models in use at German waste treatment plants. These models have an influence on capital costs as well as on operating costs. The great variety of existing models, which is not only found in theory but also in practice, is a sure indication that there is no universal solution at present but that models always have to be adapted to the current conditions governing the plant in question (e.g., tax law amendments). In view of the great complexity of this subject the following deliberations will be restricted to only the best-known types of financing model. [Deutsch] Fuer den Betrieb von Abfallbehandlungsanlagen gibt es bundesweit verschiedene Organisations- und Finanzierungsmodelle. Diese Modelle haben Auswirkungen auf die Kapitalkosten und die Betriebskosten. Die Vielfalt der nicht nur theoretisch moeglichen, sondern auch der in der Praxis existierenden Modelle ist mit Sicherheit ein Hinweis, dass derzeit keine universelle Loesung moeglich ist, sondern diese immer den aktuellen und spezifischen Verhaeltnissen (z.B. Steuerrechtsaenderung u.a.) angepasst werden muss. Auf Grund der Komplexibilitaet beschraenken sich die nachfolgenden Ausfuehrungen ausschliesslich auf die bekanntesten Formen der Finanzierungsmodelle. (orig./SR)

    One lesson to be learned from completely deregulated markets is that the national governments of the countries, in designing the national energy pricing policies, will be strongly led by macroeconomic interests, and will see to it that the transmission charges will be levelled down in the course of deregulation. Hence regional electric utilities have to get prepared for a drop in sales in their core business, as compared to pre-deregulation times. The strategy adopted by the Pfalzwerke regional utility is explained in this article. The innovative management concept proved to achieve significant cost savings permitting sustainable compatibility of the utility in the market. (orig./CB) [German] Beispiele aus liberalisierten Vorreitermaerkten zeigen, dass der Staat ein makrooekonomisches Interesse daran hat, durch ordnungspolitische Eingriffe die Preise fuer Durchleitungsentgelte drastisch zu senken. So muessen sich die regionalen Versorgungsunternehmen zukuenftig auf massive Umsatzeinbussen in dem bislang monopolgeschuetzten Kerngeschaeft vorbereiten. Die Pfalzwerke versprechen sich durch ihr innovatives Organisationskonzept mit signifikanten Kosteneinsparungen eine nachhaltige Sicherung ihrer Wettbewerbsposition im Markt. (orig./CB)

    Deutsche Bahn is presently endeavouring to further improve the interaction between the overhead wire and the current collectors on its locomotives and trainsets. The major factors behind this initiative are cost, quality and noise prevention. The outcome is the development of a completely new type of current collector for high-speed operation even on conventional track. Prototypes have meanwhile undergone practical trials on the 200 km/h line from Augsburg to Donauwoerth. The new current collector is a single-arm pantograph jointly developed by DB and Bombardier Transportation. (orig.)

    Surface water, and drinking water obtained from surface water, should be largely free of organic compounds. This applies particularly to substances that are not or poorly degradable in the environment. Pollution of surface water with poorly degradable toxic substances - especially from industrial applications - can be avoided or at least largely reduced by means of specially adapted biological waste water cleaning techniques. The compound ethylene diamine tetraacetate (EDTA), which has multiple technical applications and is used in large amounts, demonstrates that even contaminants considered to be unsuitable for biological treatment can be eliminated from waste water by means of certain biological processes employing specially enriched bacterial cultures. (orig.) [Deutsch] Oberflaechengewaesser und daraus gewonnenes Trinkwasser sollen moeglichst frei von organischen Verbindungen sein. Dies gilt insbesondere fuer Substanzen, die in der Umwelt nicht oder nur sehr langsam abbaubar sind. Eine Belastung von Oberflaechengewaessern mit schwer abbaubaren `Problemstoffen` - insbesondere aus industriellen Anwendungsbereichen - kann unter anderem mit Hilfe speziell angepasster Verfahren zur biologischen Abwasserreinigung vermieden beziehungsweise weitestgehend reduziert werden. Am Beispiel der technisch sehr vielfaeltig und in grossen Mengen eingesetzten Verbindung EDTA (Ethylendiamintetraacetat) laesst sich erkennen, dass durch bestimmte bioverfahrenstechnische Massnahmen mit Hilfe speziell angereicherter Bakterienkulturen auch als `biologieunfaehig` eingestufte Problemstoffe aus Abwaessern eliminiert werden koennen.

    Magnetic resonance imaging (MRI) of the liver has become an essential tool in the radiological diagnostics of both focal and diffuse diseases of the liver and is subject to constant change due to technological progress. Recently, important improvements could be achieved by innovations regarding MR hardware, sequences and postprocessing methods. The diagnostic spectrum of MRI could be broadened particularly due to new examination sequences, while at the same time scanning time could be shortened and image quality has been improved. The aim of this article is to explain both the technological background and the clinical application of recent MR sequence developments and to present the scope of a modern MRI protocol for the liver.

    Due to the insufficient transfer of knowledge from projects, construction company organisations do not use the potentials for their competitive advantage. In this paper a knowledge management process will be presented for the identification, classification and allocation of knowledge integrated in the controlling process of enterprises, which is bounded to civil works occurrence. The presented occurrence orientated knowledge process model was developed at the Swiss Federal Institute of Technology in Zurich. This is not a holistic knowledge management concept for a construction company; it is focused on the process and the relevant participants and users. (orig.) [German] Durch den ungenuegenden Wissenstransfer von Projektwissen werden von Bauunternehmungen potentielle Synergien zur Verbesserung der Wettbewerbsfaehigkeit nicht ausreichend genutzt. In diesem Beitrag wird ein Wissensmanagementprozess dargestellt, der an der ETH Zuerich entwickelt wurde, welcher ereignisorientiertes Wissen in Bauunternehmungen identifiziert, hinsichtlich der Zielpersonen klassifiziert und dieses Wissen zur Nutzung in Projekten bereitstellt. Fuer die Identifikation werden Instrumente des Controlling herangezogen. Dieses Wissensmanagementkonzept soll einen kontinuierlichen Verbesserungsprozess auf der Basis des ereignisorientierten Wissens einleiten, um aus positiven sowie negativen Ereignissen in den Bauprojekten zu lernen und so zu einer lernenden Organisation zu gelangen.

    Renewable energy sources currently are applied for the heat supply of Berlin only to 2%. The supply concept for the CO{sub 2} neutral city quarter at the Gasometer Schoeneberg provides for use of deep geothermal energy. An annual gross heat demand of nearly 7,000 MWh as well as a cooling requirement of nearly 5,000 MWh are expected for the site with scientific institutions, offices and restaurants.With the support of the GFZ German Research Centre for Geosciences (Potsdam, Federal Republic of Germany), the project partners GASAG Berliner Gaswerke Aktiengesellschaft (Berlin, Federal Republic of Germany) and EUREF AG (Berlin, Federal Republic of Germany) have performed first measurements in order to explore the geothermal potential of the capital city.

    Full Text Available The Romanian Parliamentary debate around the Congress of Berlin (1878-1879 offers a bird’s eye view of the evolution of antisemitic speech in Romania. Naturalization of the Jews - an issue raised by the Great European Powers during this Congress - came into conflict with the wishes of the Romania political class, which presently exploded into a violent antisemitic campaign in the political debates and public speeches. The “Jewish danger” presented by many intellectuals and politicians will be accompanied by the accusation that the Jews constitute a state within the state, a nation within the nation, both devoted to world conspiracy. Amidst this welter of accusations, antisemitic discourse grew heavy with racial arguments. But by far the main characteristic of the Romanian variant of antisemitic discourse was the rapidity of its adoption in the parliamentary debates.

    There is substantial evidence that both temperature and air pollution are predictors of mortality. Thus far, few studies have focused on the potential interactive effects between the thermal environment and different measures of air pollution. Such interactions, however, are biologically plausible, as (extreme) temperature or increased air pollution might make individuals more susceptible to the effects of each respective predictor. This study investigated the interactive effects between equivalent temperature and air pollution (ozone and particulate matter) in Berlin (Germany) and Lisbon (Portugal) using different types of Poisson regression models. The findings suggest that interactive effects exist between air pollutants and equivalent temperature. Bivariate response surface models and generalised additive models (GAMs) including interaction terms showed an increased risk of mortality during periods of elevated equivalent temperatures and air pollution. Cold effects were mostly unaffected by air pollution. The study underscores the importance of air pollution control in mitigating heat effects. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Decisions about sustainable development demand spatially differentiated evaluations. As an example, we demonstrate the evaluation of water management strategies in the cities of Berlin and Potsdam (Germany) with respect to their ecological effects in 14 sections of the surface water system. Two decision support systems were compared, namely PROMETHEE, which is designed to obtain a clear decision (linear ranking), and Hasse Diagram Technique (HDT), normally providing more than one favourable solution (partial order). By PROMETHEE, the spatial differentiation had unwanted effects on the result, negating the stakeholders determined weighting of indicators. Therefore, the stakeholder can barely benefit from the convenience of obtaining a clear decision (linear ranking). In contrast, the result obtained by HDT was not influenced by spatial differentiation. Furthermore, HDT provided helpful tools to analyse the evaluation result, such as the concept of antagonistic indicators to discover conflicts in the evaluation process.

    The emigration of Lothar Kalinowsky (1899-1992) might, at first glance, seem to be a history of coincidence and twists of fate, but it is shown to be a truly entangled and intertwined history and story. The international introduction of electroconvulsive therapy was not only closely involved with the political, scientific and economic conditions during World War II, but the story of Kalinowsky's relevance to it emerges from competing stories, told differently in Europe and the USA - and by Kalinowsky himself. Tracing these stories up to the end of the 1960s reveals Kalinowsky as an influential inheritor and patron of Berlin Biological Psychiatry, rather than telling the history of an émigré innovator of international neuropsychiatric research. © The Author(s) 2015.

    The largest measles outbreak in Berlin since 2001 occurred from October 2014 to August 2015. Overall, 1,344 cases were ascertained, 86% (with available information) unvaccinated, including 146 (12%) asylum seekers. Median age was 17 years (interquartile range: 4-29 years), 26% were hospitalised and a 1-year-old child died. Measles virus genotyping uniformly revealed the variant 'D8-Rostov-Don' and descendants. The virus was likely introduced by and initially spread among asylum seekers before affecting Berlin's resident population. Among Berlin residents, the highest incidence was in children aged asylum seekers, not always conducted, occurred later (median: 7.5 days) than the recommended 72 hours after onset of the first case and reached only half of potential contacts. Asylum seekers should not only have non-discriminatory, equitable access to vaccination, they also need to be offered measles vaccination in a timely fashion, i.e. immediately upon arrival in the receiving country. Supplementary immunisation activities targeting the resident population, particularly adults, are urgently needed in Berlin. This article is copyright of The Authors, 2017.

Der Beitrag informiert auch über die erfolgreiche Umsetzung dieser Strategie anhand zahlreicher Beispiele. Er zeigt, wie es der Staatsbibliothek in der Hauptstadt Berlin, in der viele Gedächtnisinstitutionen tätig sind, gelingt, öffentlich präsent zu bleiben und ihr Profil zu vermitteln. The public relations work of the Berlin State Library – Prussian Cultural Heritage aims at effectively presenting its globally significant treasures as well as its services for the scientific world. It is based on three pillars: cultural education for the general public, especially for people who are not naturally close to libraries; a general and wide variety of public relations work; and events which target special communities in science. The paper also presents many examples for the effectual implementation of this strategy. It shows how the State Library, in the capital city of Berlin with its many memory institutions, succeeds in keeping a strong presence and communicating its profile to the public.

    Full Text Available The mesoscale atmospheric model COSMO-CLM (CCLM with the Double Canyon Effect Parametrization Scheme (DCEP is applied to investigate possible adaption measures to extreme heat events (EHEs for the city of Berlin, Germany. The emphasis is on the effects of a modified urban vegetation cover and roof albedo on near-surface air temperatures. Five EHEs with a duration of 5 days or more are identified for the period 2000 to 2009. A reference simulation is carried out for each EHE with current vegetation cover, roof albedo and urban canopy parameters (UCPs, and is evaluated with temperature observations from weather stations in Berlin and its surroundings. The derivation of the UCPs from an impervious surface map and a 3-D building data set is detailed. Characteristics of the simulated urban heat island for each EHE are analysed in terms of these UCPs. In addition, six sensitivity runs are examined with a modified vegetation cover of each urban grid cell by -25%, 5% and 15%, with a roof albedo increased to 0.40 and 0.65, and with a combination of the largest vegetation cover and roof albedo, respectively. At the weather stations' grid cells, the results show a maximum of the average diurnal change in air temperature during each EHE of 0.82 K and -0.48 K for the -25% and 15% vegetation covers, -0.50 K for the roof albedos of 0.65, and -0.63 K for the combined vegetation and albedo case. The largest effects on the air temperature are detected during midday.

  8. Chemical and physical reservoir parameters at initial conditions in Berlin geothermal field, El Salvador: a first assessment

    A study has been made to obtain the main chemical and physical reservoir conditions of the Berlin field (El Salvador), before the commencement of large-scale exploitation of the geothermal resource. The upflow zone and the main flow path within the geothermal system have been determined from the area distribution of chemical parameters such as Cl concentrations, ratios such as Na/K, K/Mg, K/Ca, and temperatures computed from silica concentrations and cation ratios. Gas compositions have been used to calculate reservoir parameters such as temperature, steam fraction and P{sub CO{sub 2}}. The computer code WATCH (new edition 1994) has been used to evaluate the temperature of equilibrium between the aqueous species and selected alteration minerals in the reservoir. The fluid in Berlin flows to the exploited reservoir from the south, entering it in the vicinity of well TR-5. Along its flow-path (south-north direction), the fluid is cooled by boiling and conductive cooling. The chloride-enthalpy diagram indicates the existence of a parent water, with a chemical composition similar to well TR-5, that boils and the residual brine produces the fluid of well TR-3, which is very concentrated in salts. The fluid of TR-5 is probably produced from this parent water, generating the fluids of wells TR-2 and TR-9 by boiling, and the fluids of wells TR-1 and TR-4 by conductive cooling. The computed values for the deep steam fraction clearly indicate that this is a liquid-dominated system, with computed temperature values decreasing from 310{sup o}C (upflow zone) to about 230{sup o}C, from south to north.

    For the further investigation of the large scale transport and chemical transformation of air pollutants with atmospheric models reliable emission data with a high temporal, spatial and species resolution are required for Europe. Within the GENEMIS project methods and models have been developed to generate such data, starting from annual emission data of the CORINAIR and LOTOS inventories. The main objective of converting annual emission data into reliable hourly values has been reached on the basis of numerous socio-economical, meteorological and technical indicator data. The models which were developed within this framework have been used to generate european emission inventories for different base years and selected episods. The analysis of the results showed significant spatial and large temporal variations of the emissions. It has been shown that former simplifying assumptions concerning the temporal behaviour of emissions were not sufficient to describe real situations. The emission data calculated within GENEMIS have been used directly as an input for air quality modeling purposes. (orig.) [Deutsch] Zur weiteren Erforschung des grossraeumigen atmosphaerischen Transports und der chemischen Umwandlung von Luftverunreinigungen mit Hilfe von entsprechenden Simulationsmodellen werden zeitlich, raeumlich und stofflich hochaufgeloeste Emissionsdaten fuer Europa benoetigt. Im Rahmen des Forschungsvorhabens GENEMIS wurden Methoden und Modelle entwickelt, mit denen - ausgehend von den jaehrlichen Emissionskatastern von CORINAIR und LOTOS - hochaufgeloeste Emissionsdaten in Europa ermittelt werden koennen. Die im Vordergrund stehende zeitliche Disaggregierung in stuendliche Emissionswerte wurde dabei auf der Grundlage zahlreicher sozio-oekonomischer, meteorologischer und technischer Indikatordaten vorgenommen. Die entwickelten Modelle wurden zur Erstellung von hochaufgeloesten Emissionsdatensaetzen fuer verschiedene Bezugsjahre und -zeitraeume angewendet. In der

    A liquid nitrogen pump with contactless superconducting magnetic bearings was to be developed on the basis of an available motor with superconducting bearings. Contactless superconducting magnetic bearings require practically no servicing. A high demand for pumps for cryogenic liquids is expected with the impending use of hydrogen as an energy source. The pumping of liquid nitrogen was demonstrated successfully with the new test aggregate. The maximum pumped volume was 17 l/min at a lift of 0.5 m and 6 l/min at a lift of 1 m. In all, 15 hours of operation were registered in the superconducting state of the bearing, which included 2 hours of uninterrupted pump operation. The higher speed range for which magnetic bearings are optimally suited was not reached. Operation at higher frequencies was impossible either because of stronger resonance amplituees or because the power system was too weak. [German] Ziel des Vorhabens war die Entwicklung einer Pumpe fuer fluessigen Stickstoff mit beruehrungslosen supraleitenden Magnetlagern auf der Basis eines vorhandenen supraleitend gelagerten Motors. Die beruehrungslose supraleitende Magnetlager sind praktisch wartungsfrei. Ein Bedarf an Pumpen fuer kryogene Fluessigkeiten entsteht insbesondere durch den in naher Zukunft zu erwartenden Einsatz von Wasserstoff als Energietraeger. Mit dem entworfenen Aggregat wurde das Pumpen von Fluessigstickstoff erfolgreich demonstriert. Der Foerderstrom betrug bei 0,5m Foerderhoehe maximal 17 l/min; beim 1m Foerderhoehe wurden maximal 6 l/min gemessen. Es wurden insgesamt ca. 15 Betriebsstunden in supraleitenden Zustand des Lagers, darunter 2 Stunden ununterbrochener Pumpbetrieb registriert. Der hoehere Drehzahlbereich, fuer den das Magnetlager eigentlich paedestiniert ist, konnte nicht erreicht werden. Ein Betrieb bei hoeheren (Ist-)Frequenzen war nicht moeglich, entweder durch staerkere Resonanzausschlaege oder durch einen zu schwachen Antrieb. (orig.)

    Small villages, solitary farms, alpine dairy farms etc. usually have no connection to the supply and disposal systems of municipal or public utilities. Since mountain huts in particular are often situated in ecologically sensitive areas (e.g. the Alps), their operation requires an efficient use of water and energy. Present-day power supply concepts for stand-alone systems are mostly based on solar cells with a battery storage and a diesel generator for peak load management and periods of bad weather. If wastewater discharge and waste disposal are also taken into account it is necessary to take a new all-inclusive ecological view of the system, since the energy demand of the disposal systems can double that of the entire site. This calls for new, comprehensive supply and disposal systems which permit reliable, energy self-sufficient operation. This paper presents the individual components of an energy self-sufficient supply and disposal system for remote locations comprising energy and water supply, wastewater treatment and organic waste treatment. [German] Kleine Ortschaften, Aussiedlerhoefe, Almhuetten etc. liegen meist abseits der ueblichen Ver- und Entsorgungssysteme kommunaler oder oeffentlicher Anbieter. Da besonders Berghuetten (z.B. in den Alpen) ausserdem haeufig in oekologisch sehr sensiblen Gebieten liegen, ist es notwendig, die Ressourcen Wasser und Energie rationell zu verwenden. Die derzeitigen Energiekonzepte fuer die Stromversorgung von Inselsystemen basieren meist auf der Verwendung von Solarzellen mit Batteriespeicher und einem Dieselaggregat, um Spitzenbelastungen und Schlechtwetterperioden zu ueberbruecken. Die Einbeziehung der Wasser- und Abfallentsorgung erfordert neue gesamtoekologische Betrachtungsweisen, da der Energiebedarf fuer die Entsorgung den Energieverbrauch der gesamten Inselsysteme verdoppeln kann. Hier sind neue und unfassende Ver- und Entsorgungskonzepte gefragt, die einen gesicherten autarken Betrieb ermoeglichen. Im vorliegenden

    Advanced simulation tools were used in developing the climate design for the roof covering the taller of the two blocks at Moscow's Federation Tower. The all-glass roof space at a height of 365 m is designed to accommodate the finest and most exclusive hotel areas. Several restaurants, bars and lounges and a Sky Dance Club will offer entertainment and fabulous views across the whole city. Simulations were used to develop and verify a design that ensures thermal comfort taking into account architectural, climate and utilisation requirements. The structure and the building services were simulated based on a 3D model, and simulations were carried out for summer and winter scenarios. This paper describes the design process including load calculations and the development and assessment of the climate design by means of simulation.

    As an essential part of forest environmental monitoring, the Forest State Report 2013 shows how environmental factors influence the development of our forests. In addition to the annual survey of the crown state, intensive land surveys were established by the country, which provide extensive results over a long period. Data on the status and growth of the tree, the nutrient cycle, the material intake, soil status, soil vegetation and meteorology, ie the dynamics of environmental changes, are collected. Fortunately, the Forest State Report in 2013 shows that the state of the forests in Baden-Wuerttemberg has slightly improved compared to the previous year. This means that the trend towards the improvement of forest conditions continues after the extreme drought year 2003. This improvement is attributable to the spring weather which is favorable to the forest as well as to a generally low occurrence of harmful insects. [German] Als wesentlicher Teil des forstlichen Umweltmonitorings zeigt der Waldzustandsbericht 2013, wie Umweltfaktoren die Entwicklung unserer Waelder beeinflussen. Ergaenzend zur jaehrlichen Erhebung des Kronenzustandes wurden durch das Land Intensivmessflaechen eingerichtet, die umfangreiche Ergebnisse ueber einen langen Zeitraum liefern. Dort werden Daten zu Baumzustand und -wachstum, Naehrstoffkreislauf, Stoffeintrag, Bodenzustand, Bodenvegetation sowie Meteorologie, also die Dynamik der Umweltveraenderungen, erhoben. Erfreulicherweise zeigt der Waldzustandsbericht 2013, dass sich der Zustand der Waelder in Baden-Wuerttemberg gegenueber dem Vorjahr leicht verbessert hat. Damit setzt sich der Trend zur Verbesserung des Waldzustandes nach dem extremen Trockenjahr 2003 weiter fort. Diese Verbesserungstendenz laesst sich auf die fuer den Wald guenstige Fruehjahrswitterung sowie auf ein allgemein geringes Vorkommen an Schadinsekten zurueckfuehren.

Die beiden Institutsdirektoren am Anfang des 20sten Jahrhunderts waren Vertreter der allumfassenden Geologie des 19ten Jahrhunderts, während die beiden folgenden Direktoren eine Geologie ohne Paläontologie vertraten. Das führte zu einer Trennung der beiden Richtungen, und nach der III. Hochschulreform der DDR 1968 verblieb allein die sammlungsbezogene Paläontologie am Museum. Nach der Wiedervereinigung wurde ein Institut für Paläontologie mit biologischer Ausrichtung mit zwei Professuren, einer für Paläozoologie und einer für Paläobotanik, eingerichtet. The development of the Geologisch-Paläontologisches Institut und Museum of the Museum für Naturkunde at the Humboldt University (formerly Friedrich-Wilhelm-Universität in Berlin from a geology-paleontology institution to a pure paleontology institution is described. The first two directors of the department in the beginning of the 20th century, Prof, von Branca and Prof. Pompeckj, represented a 19th century concept of a geology, which included paleontology, even vertebrate paleontology as the crown jewel of geology. They fought sometimes vigorously against a separation of paleontology from geology. The next two directors. Prof. Stille and Prof, von Bubnoff, were the leading geologists in Germany; to be a student of Stille was a special trade mark in geology of Germany. They represented a geology centered on tectonics. The separation of paleontology as separate section was prepared. The destructions of the Second World War, the following restaurations and the division of Germany into two States influenced strongly their directorships. The education of geologists

This why application of this technology for water heating or space heating in the residential sector as well as, to some part, in small-sized business, is promoted by a variety of schemes offering financial incentives. Such schemes are offered by gas utilities, serving the purposes of customer services, or demand-side management (DSM), or market expansion and environmental policy.

    The marine environment of the North Sea and Baltic Sea is still heavily polluted. The marine ecosystems are under severe stress from overfishing, water pollution, raw materials production and tourism. Environmental protection in this region necessitates decisive political initiatives and strict corrections especially in fishery policy, agricultural policy and chemical substances control. This is the balance of the special expert opinion of the Council of Environmental Experts. The publication specifies the main problem areas, the current pollution situation, the fields where action is most urgently required - especially in fishery, chemical substances, agricultural and sea travel policies - and presents suggestions for an integrated European and national marine protection policy including a regional development concept for the marine environment.

    Double layer capacitors are the system of choice whenever a large number of cycles and high capacity are required. They have the advantages of high cyclic strength, high capacity, freedom of servicing, insensitivity to high temperatures and long life. Drawbacks are low energy density, high self-discharge and high cost.Applications in water pumps, pathfinders and roller blind control systems were investigated. [German] Mit den Ergebnissen steht ein detailliertes Wissen ueber den weltweiten Entwicklungsstand und die physikalischen Eigenschaften von Doppelschichtkondensatoren zur Verfuegung. Ihre Eigenschaften wurden in Bezug auf moegliche photovoltaische Anwendungen hin analysiert. Anwendungsfehlder ergeben sich vorzugsweise dann, wenn hohe Zyklenzahl und Leistungsfaehigkeit gefordert werden. Die Vorteile des neuen Energiespeichers sind seine hohe Zyklenfestigkeit und Leistungsfaehigkeit, seine Wartungsfreiheit, Temperaturunempfindlichkeit und lange Lebensdauer. Ihnen stehen die Nachteile einer geringen Energiedichte, hohen Selbstentladung und hoher Kosten gegenueber. Eine deutliche Steigerung der Gesamteffizienz von photovoltaischen Versorgungseinheiten beim Einsatz von Doppelschichtkondensatoren ergeben energetische Simulationen unterschiedlicher Systeme. Fuer ausgewaehlte photovoltaisch versorgte Anwendungen konnte die Einsatzfaehigkeit von Doppelschichtkondensatoren in Feldtests erprobt und nachgewiesen werden. Wasserpumpensysteme, Pathfinders und eine Rolladensteuerung fuer ein Fenster wurden getestet. Der Einsatz von Doppelschichtkondensatoren zur weiteren Verbreitung photovoltaischer Anwendungen ist bereits heute fuer spezielle Anwendungen sinnvoll und wirtschaftlich. Mit weiter fallenden Preisen fuer die Kondensatoren und der Entwicklung von Kondensatorsystemen mit hoeheren Spannungen werden weitere Anwendungsfelder hinzukommen.

    With the ongoing application of new materials (Al, Mg, Plastic) as an alternative to steel in light-weight body in white construction it is necessary to develop and use other joining and fixing technologies than spot welding, bolt-and nut-welding. These new technologies for example are mechanical joining technology as clinching and self-pierce-riveting, blind-riveting and special elements to fix other parts as blind-rivets and self-piercing nuts and bolts. These products are mainly used for metal materials and mixed structures. To fix other parts to plastic-parts direct-screwing or the after-moulding-technology with metal or plastic inserts is used.

[German] Mit der verstaerkten Anwendung von weiteren Werkstoffen (Al, Mg, Kunststoffe) als Stahl im Automobilbau ist die Notwendigkeit erwachsen, alternative Fuege- und Befestigungstechniken zum Punktschweissen, Bolzen- und Mutternschweissen zu entwickeln. Hierzu gehoeren die mechanischen Fuegetechniken wie Stanznieten, Clinchen, Blindnieten sowie die sogenannten Funktionselemente zum Befestigen von Anbauteilen, wie Blind- und Stanznietmuttern und -bolzen. Diese Verfahren werden ueberwiegend fuer metallische Werkstoffe oder bei Mischbauweise angewandt.

    Guidelines issued by European and German cardiology societies clearly define procedures for treatment of acute myocardial infarction (AMI). These guidelines, however, are based on clinical studies in which older patients are underrepresented. Older patients, on the other hand, represent a large and growing portion of the infarction population. It was our goal in the present paper to analyse the present treatment of AMI patients over 75 years of age in the city of Berlin, Germany, with data gained from the Berlin Myocardial Infarction Registry (BHIR). We prospectively collected data from 5079 patients (3311 men and 1768 women, mean age 65.6) with acute myocardial infarction who were treated in 25 hospitals in Berlin during the period 1999-2003. 1319 patients (25.9%) were older than 75 (mean age 82.5 years). Overall hospital mortality rate was 11.6%. In patients over 75, this rate was 23.9%; among the younger infarction population, it was 7.3%. In contrast to the younger AMI patients, the majority of those over 75 were female (62.5 vs 25.1% for the younger) and demonstrated a significantly higher frequency of all prognostically meaningful comorbidities (heart failure 14.4% vs. 3.5%; renal failure 11.5 vs 3.9%; diabetes 37.3 vs 24.3%). Clinical signs of severe infarction, moreover, were more common among the aged patients (pulmonary congestion 45.4 vs 19.7%; left bundle branch block 12.7 vs 3.6%). Pre-hospital time was prolonged (2.8 vs 2 h) and guideline-recommended therapy was applied significantly less frequently to AMI patients over 75 (reperfusion therapy 39.8 vs 71.7%, beta-blockers 62.8 vs 78.3%, statins 26.5 vs 45.5%). Multivariate analysis revealed the following factors to be independent predictors of hospital mortality in patients over 75: age (OR 1.05 per year), acute heart failure (OR 2.39), pre-hospital resuscitation (OR 10.6), cardiogenic shock (OR 2.73), pre-hospital delay >12 h (OR 1.68), and ST elevation in the first ECG (OR 2.09).

    Full Text Available In the early 1980s, hundreds of men and women in many West German and West European cities resorted to a rather unusual form of protest. In order to express their dissatisfaction with the local housing situation and policies, they occupied empty apartment buildings and, under the eyes of an astonished public, began renovating them themselves. Focusing on West Berlin as the most prominent case, this article interprets the performance of DIY home improvement tasks in occupied buildings (Instandbesetzer, as they called themselves as a form of protest, thus drawing attention to the manual work done by squatters and its impact on the housing policies of the 1980s. The DIY measures undertaken publicly by the squatters drew attention to serious political and social shortcomings while at the same time demonstrating possible solutions. The visible (or at least announced transformation of the built environment forced politicians, the public, and experts alike to discuss both housing policy in general and the idea of self-help as suggested by the squatters. Squatters thus accelerated the readjustment of a housing policy which now incorporated manual self-help by tenants into West Berlin’s city planning, but by the same token also undermined the potential for protest and provocation of such practices. * * * Zu Beginn der 1980er-Jahre griffen Hunderte von Männern und Frauen in vielen westdeutschen und westeuropäischen Städten zu einem ungewöhnlichen Mittel, um gegen ihre Wohnsituation und die Wohnungspolitik zu protestieren: Sie begannen, leerstehende Häuser eigenhändig und öffentlichkeitswirksam zu renovieren, die sie vorher besetzt hatten.

    There are minimal data regarding chronic management of single-ventricle ventricular assist device (VAD) patients. This study aims to describe our center's multidisciplinary team management of single-ventricle patients supported long term with the Berlin Heart EXCOR Pediatric VAD. Patient #1 was a 4-year-old with double-outlet right ventricle with aortic atresia, L-looped ventricles, and heart block who developed heart failure 1 year after Fontan. She initially required extracorporeal membrane oxygenation support and was transitioned to Berlin Heart systemic VAD. She was supported for 363 days (cardiac intensive care unit [CICU] 335 days, floor 28 days). The postoperative course was complicated by intermittent infection including methicillin-resistant Staphylococcus aureus, intermittent hepatic and renal insufficiencies, and transient antithrombin, protein C, and protein S deficiencies resulting in multiple thrombi. She had a total of five pump changes over 10 months. Long-term medical management included anticoagulation with enoxaparin, platelet inhibition with aspirin and dipyridamole, and antibiotic prophylaxis using trimethoprim/sulfamethoxazole. She developed sepsis of unknown etiology and subsequently died from multiorgan failure. Patient #2 was a 4-year-old with hypoplastic left heart syndrome who developed heart failure 2 years after bidirectional Glenn shunt. At systemic VAD implantation, he was intubated with renal insufficiency. Post-VAD implantation, his renal insufficiency resolved, and he was successfully extubated to daytime nasal cannula and biphasic positive airway pressure at night. He was supported for 270 days (CICU 143 days, floor 127 days). The pump was upsized to a 50-mL pump in May 2011 for increased central venous pressures (29 mm Hg). Long-term medical management included anticoagulation with warfarin and single-agent platelet inhibition using dipyridamole due to aspirin resistance. He developed increased work of breathing requiring

    Full Text Available Background: With the decision to extend the airport Berlin-Schönefeld to the new airport Berlin Brandenburg International (BER in 2006, a construction of superlatives has emerged. One of the biggest challenges was the supply of around 2.5 million cubic meters of high quality concrete that had to be produced for the construction of the airport. Due to the scale of this enterprise as well as its environment, the logistic solution of raw material supply has to be found.       Method: The planning of the concrete supply chain for the airport construction site BER had to be carried out with two major goals: the stability of the supply chain to assure that the demands of the construction site are met and delays are prevented, as well as assurance of the high quality standards of the concrete production and to avoid an alkali silica reaction and the resulting unavoidable disaggregation of the concrete. External effects, such as the carbon dioxide emission and the effect of the supply chain on adjoining residents were key factors that had to be integrated in a holistic supply chain concept.  The principle underlying method is an analysis of limiting conditions for two approaches: a centralized supply chain with on-site concrete factory and upstream transport of raw materials versus a decentralized supply chain with off-site factories and downstream transport of ready-mixed concrete. Results: The analysis of constraints and the effects on key requirements of the concrete supply chain for the BER airport construction site lead to the installation of the most modern concrete plant in Europe. The benefits of a centralized supply chain are significant. On one hand, the high quality standards can be met with the on-site mixture of the concrete and centralized quality assurance, on the other hand, the majority of the supply traffic for the construction site was moved from the road to train-bound logistics, meeting the emission requirements of the

    Thiopurine methyltransferase (TPMT)is involved in the metabolism of thiopurines such as 6-mercaptopurine and 6-thioguanine. TPMT activity is significantly altered by genetics, and heterozygous and even more homozygous variant people reveal substiantially decreased TPMT activity. Treatment for childhood acute lymphoblastic leukemia (ALL) regularly includes the use of thiopurine drugs. Importantly, childhood ALL patients with low TPMT activity have been considered to be at increased risk of developing therapy-associated acute myeloid leukemia and brain tumors. In the present study, we genotyped 105 of 129 patients who developed a secondary malignant neoplasm after ALL treatment on 7 consecutive German Berlin-Frankfurt-Münster trials for all functionally relevant TPMT variants. Frequencies of TPMT variants were similarly distributed in secondary malignant neoplasm patients and the overall ALL patient population of 814 patients. Thus, TPMT does not play a major role in the etiology of secondary malignant neoplasm after treatment for childhood ALL, according to Berlin-Frankfurt-Münster strategies.

    In May 2017, at least 12 dogs showed signs of acute neurotoxicosis after swimming in or drinking from Lake Tegel, a mesotrophic lake in Berlin, Germany, and several of the affected dogs died shortly afterwards despite intensive veterinary treatment. Cyanobacterial blooms were not visible at the water surface or the shorelines. However, detached and floating water moss ( Fontinalis antipyretica ) with high amounts of Tychonema sp., a potential anatoxin-a (ATX) producing cyanobacterium, was found near the beaches where the dogs had been swimming and playing. Necropsies of two of the dogs revealed no specific lesions beside the anamnestic neurotoxicosis. ATX was detected in concentrations up to 8700 µg L -1 in the stomach contents, while other (neuro)toxic substances were not found. In the aqueous fraction of Fontinalis / Tychonema clumps sampled after the casualties, ATX was found in concentrations up to 1870 µg L -1 . This is the first report of a dense population of Tychonema sp. in stands of Fontinalis resulting in high ATX contents. This case emphasizes the need for further investigation of potentially toxic, non-bloom forming cyanobacteria in less eutrophic water bodies and underlines the novel challenge of developing appropriate surveillance schemes for respective bathing sites.

    The Berlin Project for Primary Prevention of Child Sexual Abuse by Juveniles (PPJ) offers diagnostic and therapeutic help to 12-to-18-year-old juveniles with a sexual preference for the prepubescent and/or early pubescent body of children and who apply for treatment on a voluntary basis. The project goal is to prevent primary or recurrent child sexual abuse as well as primary or recurrent use of child abuse images. Treatment aims to enable affected juveniles to obtain control over their conflictual sexual behaviors. In the present article, the origin of the PPJ; its main approach, including the conception of a media campaign; as well as results from the first year of a three-year study are presented. Further, initial characterizations of juveniles taking part in the project for the first 12 months are provided. The results confirmed that the group of 12-to-18-year-old juveniles with a sexual preference for prepubescent and/or early pubescent minors exists as a target group for primary preventive measures and that they can be assessed for their sexual preferences.

  17. Public participation in post-Fordist urban green space governance: the case of community gardens in Berlin.

    Science.gov (United States)

    Rosol, Marit

    2010-01-01

    This article examines citizen participation in the governance of contemporary urban green space. Rather than exploring normative questions of ideal forms of participatory democracy, it focuses on changing roles and relationships between local state and non-state actors in order to identify and explain the changing nature of participation. I argue that neoliberal urban restructuring has changed the conditions for participation and thus participation itself in fundamental ways and that we need an account of changes in statehood and governance in order to capture this conceptually. Based on the case of community gardens in Berlin, the article discusses the extent to which this changed relationship is expressed by current citizen participation as well as the potential and problems that result from it. My empirical results show the emergence of a new political acceptance of autonomously organized projects and active citizen participation in urban green space governance. The central argument of this article is that this new acceptance can be conceptualized as an expression of the neoliberalization of cities. Nevertheless, this neoliberal strategy at the same time leads to complex and contradictory outcomes and the resulting benefits are also acknowledged.

    Since 1999, Germany has experienced at least twelve serious cases of targeted school violence. This article describes two projects designed to fill the gap between universal prevention and emergency response in preventing severe forms of school violence in Germany. The Berlin Leaking Project examined the viability of preventive efforts based on early identification of leaking behavior that often precedes targeted school attacks. Leaking refers to any behavior or communication that indicates a student is preparing to carry out a violent attack. This would include explicit or implied threats of violence, apparent fascination with prior acts of violence such as Columbine, and any evidence of planning or preparation to carry out an attack. The NETWASS project will test a training program and intervention strategy based on those findings, examining the usefulness of a threat assessment approach to prevent violence by training teachers to recognize leaking behavior by students. This approach is extended by training teachers on a larger scale to identify leaking and then having a school-based team evaluate the student and initiate appropriate interventions, such as mental health services, and in some cases, law enforcement action.

    There is substantial evidence that both temperature and air pollution are predictors of mortality. Thus far, few studies have focused on the potential interactive effects between the thermal environment and different measures of air pollution. Such interactions, however, are biologically plausible, as (extreme) temperature or increased air pollution might make individuals more susceptible to the effects of each respective predictor. This study investigated the interactive effects between equivalent temperature and air pollution (ozone and particulate matter) in Berlin (Germany) and Lisbon (Portugal) using different types of Poisson regression models. The findings suggest that interactive effects exist between air pollutants and equivalent temperature. Bivariate response surface models and generalised additive models (GAMs) including interaction terms showed an increased risk of mortality during periods of elevated equivalent temperatures and air pollution. Cold effects were mostly unaffected by air pollution. The study underscores the importance of air pollution control in mitigating heat effects. -- Highlights: • Interactive effects between air pollution and equivalent temperature result in augmented excess mortality. • High levels of ozone and particulate matter increase adverse heat effects on human mortality. • Cold effects are mostly unaffected by air pollution. • Findings underscore the importance of air pollution control in mitigating heat-related mortality. -- Interactive effects between air pollution and elevated (equivalent) temperatures underscore the importance of air pollution control in mitigating the adverse effects of heat

    Full Text Available Transport and its side effects are major problems in rapidly growing cities. Car traffic dominates these cities and pollutes the environment without being able to sufficiently secure the mobility of the urban population and goods. A paradigm shift in urban and transport policy will be necessary to change this situation. In spite of its different development dynamics, Berlin is an interesting example to discuss development strategies for rapidly growing cities because in the course of more than 100 years, a twofold paradigm shift has occurred in the city both conceptually and practically:  Berlin has shifted from a city dominated by rail traffic  to an automobile-oriented city,  and has then gradually transformed back into a city in which  an intertwined system of public and non-motorized individual means of transport secures the mobility of the urban population. The interdependencies on the conceptual level between urban planning and transport policies as well as on a practical level between urban structures and transport systems can be studied using the example of Berlin. Experiences with the implementation of automobile-oriented planning and the special conditions in the first decade after reunification led to protests, reflection, and a revision of the transport policy. A strategically designed process of integrated planning has brought about a trend reversal, and steered the development of transport in the direction of clearly formulated sustainability-oriented objectives. In this process, the reintegration of transport and spatial planning and a reorganization of institutional structures at the administrative level was of particular importance. Compact, rail-oriented settlement structures like in the metropolitan region of Berlin make it easier to dispense with automobiles than sprawled structures. The residual role that qualitatively improved automobiles will take in the cities of the future will have to be determined by research and

    The annual forest status report 2014 shows that the persistently high burdens have not fundamentally improved the health of the forests. In addition to significant improvements in soil conditions, which can be traced back to successful forest calcifications, climate change with its various impacts is a lasting burden on the forests. Unfortunately, the forest situation has deteriorated considerably compared to the previous year. With 42 per cent damaged trees, the third highest value has been reached since the start of the recordings about 3 years ago. This means that the medium-term trend towards the improvement of the forest state unfortunately does not continue. This is clearly evident in the crown condition as an important indicator of the health of the trees. The average needle / leaf loss of the trees has increased by 3.7 percentage points to 25.8 percent. The share of undamaged forest areas has fallen by nine percentage points to just 24 percent. These changes can be attributed to the very dry spring weather, the presence of harmful insects and a strong fruit formation. [German] Der jaehrliche Waldzustandsbericht 2014 zeigt, dass durch die unveraendert hohen Belastungen der Gesundheitszustand der Waelder sich nicht grundsaetzlich gebessert hat. Neben deutlichen Verbesserungen im Bodenzustand, die auf erfolgreiche Waldkalkungen zurueck zu fuehren sind, stellt insbesondere der Klimawandel mit seinen verschiedenen Auswirkungen eine dauerhafte Belastung der Waelder dar. Leider hat sich der Waldzustand gegenueber dem Vorjahr deutlich verschlechtert. Mit 42 Prozent geschaedigter Baeume wird der dritthoechste Wert seit Beginn der Aufnahmen vor rund 3 Jahren erreicht. Damit setzt sich der mittelfristige Trend zur Verbesserung des Waldzustandes leider nicht weiter fort. Beim Kronenzustand als wichtigem Indikator fuer den Gesundheitszustand der Baeume zeigt sich dies deutlich. Der mittlere Nadel-/Blattverlust der Baeume hat sich um 3,7 Prozentpunkte auf 25,8 Prozent

    This preparatory study, ``Shaft barriers for underground waste repositories in abandoned salt mines``, was to demonstrate the current scientific and technological know-how based on a comprehensive analysis of the barrier design concepts or established structures intended to serve as barriers in abandoned shafts of potash or rock salt mines. Taking as a basis the current regulatory regime and the available know-how on barrier systems in underground waste repositories taken into account so far in plan approval and licensing procedures, as well as the state of the art, concepts are developed as technical guides and models of barrier systems for mine shafts. The required research work for the various components of a shaft barrier is shown, particularly relating to aspects such as materials suitability and technical realisation. Immediate demand for research activities is shown with regard to the available potentials of mathematic and numeric geotechnical and hydrogeologic calculation models required in order to give proof of the long-term workability of shaft barriers. The authors are of the opinion that the following activities are required in order to meet the research demand quantified: (1) Laboratory and bench-scale experiments for determination of the efficiency of various sealing materials and backfilling materials, and (2) an in-situ, large-scale experiment in order to demonstrate the suitability of low-consolidation shotter columns, or constructional technologies. The laboratory work can be done in the facilities of the GSF research mine of Asse, the Freiburg Mining Academy, and the Institut fuer Gebirgsmechanik in Leipzig, and the benchmark experiments also at the Asse site in the research mine. The Kali und Salz Beteiligungs AG is prepared to offer its mine Salzdetfurth II as a site for the large-scale experiment. (orig.)

Die Evaluation der Kampagne kam bezueglich der externen Wirkungen zu ueberwiegend positiven Ergebnissen: Die zentralen Zielgruppen, Handwerker und der Ein-/Zweifamilienhausbesitzer, wurden durch die Kampagne gut erreicht und mit gutem Informationsmaterial angesprochen. Darueber hinaus schaetzte ca. ein Viertel der Haushalte, die eine solarthermische Anlage installierten, den Einfluss der Kampagne eher hoch ein. Allerdings vermissten die Haushalte zum Teil weiterfuehrende Informationen. Auch die befragten Handwerker aeusserten eine relativ grosse Zufriedenheit mit der Kampagne. Sie nutzten die bereitgestellten Informationsmaterialien der Kampagne jedoch nur sehr selten. Die Evaluation der internen Grundlagen und Prozesse fuehrt zu ambivalenten Ergebnissen: Beispielsweise ist es der Kampagne auf der einen Seite gelungen, eine breite und heterogene Traegerschaft zu gewinnen und flexibel auf aeussere Anforderungen zu reagieren. Auf der anderen Seite stellten sich Probleme in der Steuerung und im Konfliktmanagement ein. Hierzu trugen u.a. eine nicht ausreichend integrierte Projektplanung sowie strukturelle Unterschiede zwischen den Partnern bei. Die Evaluation muendet in der zentralen Empfehlung, die Kampagne in modififizierter Form fortzusetzen. Verbesserungsmoeglichkeiten sehen die Evaluatoren u.a. in der verstaerkten Einbindung regionaler Aktvitaeten.

    The aim of the research project is the development of a technique for reasonably priced mass- production of large area holographic focussers for photo-electrics. The holograms up to 1 m{sup 2} in size simultaneously act as spectrum dispersing and focussing optical elements, which focus the sunlight in discrete bands on spectrally matched solar cells. The three most important characteristics of the holographic focussers are the refractive efficiency, the spectrum bandwidth and the central working wavelength. The optimum values of the parameters conditional on the variation of the layer thickness and the mean refractive index via the aperture of the hologram and on the ability of the layer to make large modulations of the refractive index possible. The mass-production of large format holographic lenses demands precise coating of the carrier substrate of the hologram copies with dichromate gelatine and is done with the aid of a scanning copying process. (orig.) [Deutsch] Ziel des Forschungsvorhabens ist die Entwicklung einer Technololgie fuer die preiswerte serielle Herstellung von grossflaechigen holographischen Konzentratoren fuer die Photovoltaik. Die bis zu 1 m{sup 2} grossen Hologramme wirken gleichzeitig als spektral dispergierende und fokussierende optische Elemente, die das Sonnenlicht in diskreten Baendern auf spektral angepasste Solarzellen konzentrieren. Die drei wichtigsten Charakteristiken der holographischen Konzentratoren sind die Beugungseffizienz, die spektrale Bandbreite und die zentrale Arbeitswellenlaenge. Die optimalen Werte dieser Parameter sind eindeutig durch die Variation der Schichtdicke und des mittleren Brechungsindexes ueber die Apertur des Hologramms sowie durch die Faehigkeit der Schicht, grosse Brechnungsindexmodulation zu ermoeglichen, bedingt. Die serielle Fertigung der grossformatigen holographischen Linsen verlangt eine praezise Beschichtung der Traegersubstrate der Hologrammkopien mit Dichromat-Gelatine und erfolgt mit Hilfe eines

    In order to carry out a study of wafer patterning, equipment was developed for safe handling of silicon wafers from 2 to 8 inch diameters. The unit can be safely and relatively straightforwardly operated by personnel, using a wide range of etchants and electrochemical deposition processes. The design also allows the effects of electrolyte flowrate in the process chamber confronting the silicon wafer, to be assessed. These features were utilised to study copper and nickel electrodeposition to pattern the wafer surface. (orig.)

    The investigation focused on controlled hydrological storage system. Existing operating schedules and new control options were analyzed, classified and generalized in order to obtain a standardized terminology and operating concept. This generalized approach will do away with the need for system-specific analyses and models for every single new system.

Dabei bestand das Ziel darin, bestehende Betriebsplaene und neue praktikable Steuerungsmoeglichkeiten zu analysieren, zu klassifizieren und so zu generalisieren, dass eine einheitliche Terminologie und Konzeption zum Betrieb von Speichern entstand. Dieses Konzept erlaubt, in Verbindung mit den Prinzipien aus der Modellierung von Flussgebieten, verschieden strukturierte Speichersysteme mit unterschiedlichsten Steuerungsvorschriften abzubilden. Damit erhaelt man den Vorteil einer generalisierten Anwendung im Gegensatz zu einer fuer den speziellen Fall konzipierten und nicht uebertragbaren Einzelloesung.

    Full Text Available Urban air quality and human health are among the key aspects of future urban planning. In order to address pollutants such as ozone and particulate matter, efforts need to be made to quantify and reduce their concentrations. One important aspect in understanding urban air quality is the influence of urban vegetation which may act as both emitter and sink for trace gases and aerosol particles. In this context, the "Berlin Air quality and Ecosystem Research: Local and long-range Impact of anthropogenic and Natural hydrocarbons 2014" (BAERLIN2014 campaign was conducted between 2 June and 29 August in the metropolitan area of Berlin and Brandenburg, Germany. The predominant goals of the campaign were (1 the characterization of urban gaseous and particulate pollution and its attribution to anthropogenic and natural sources in the region of interest, especially considering the connection between biogenic volatile organic compounds and particulates and ozone; (2 the quantification of the impact of urban vegetation on organic trace gas levels and the presence of oxidants such as ozone; and (3 to explain the local heterogeneity of pollutants by defining the distribution of sources and sinks relevant for the interpretation of model simulations. In order to do so, the campaign included stationary measurements at urban background station and mobile observations carried out from bicycle, van and airborne platforms. This paper provides an overview of the mobile measurements (Mobile BAERLIN2014 and general conclusions drawn from the analysis. Bicycle measurements showed micro-scale variations of temperature and particulate matter, displaying a substantial reduction of mean temperatures and particulate levels in the proximity of vegetated areas compared to typical urban residential area (background measurements. Van measurements extended the area covered by bicycle observations and included continuous measurements of O3, NOx, CO, CO2 and point

    Provision of observational data with high spatial coverage over extended time periods still remains as one of the biggest challenges in urban climate research. Classical meteorological networks are seldomly designed to monitor atmospheric conditions in a broad variety of urban environments, though the heterogeneity of urban structures leads to distinct thermal characteristics on local scales, i.e., hundreds of metres to several kilometres. One approach to overcome the aforementioned challenges of observation networks is to use data from weather stations that are maintained by citizens. The private company 'netatmo' (www.netatmo.com) produces and distributes such citizen weather stations (CWS) around the world. The stations automatically send their data to the netatmo server, and the user decides if data are publicly shared. Shared data can freely be retrieved via an application programming interface. We collected air temperature (T) data for the year 2015 for the city of Berlin, Germany, and surroundings with more than 1500 'netatmo' CWS in the study area. The entire data set was thoroughly quality checked, and filter techniques, involving data from a reference network, were developed to address different types of errors associated with CWS data. Additionally, the accuracy of 'netatmo' CWS was checked in a climate chamber and in a long-term field experiment. Since the terms 'urban' and 'rural' are ambiguous in urban climate studies, Stewart and Oke (2012) developed the 'local climate zone' (LCZ) concept to enhance understanding and interpretation of air temperature differences in urban regions. LCZ classification for the study region was conducted using the 'WUDAPT' approach by Bechtel et al. (2015). The quality-checked CWS data were used to analyse T characteristics of LCZ classes in Berlin and surroundings. Specifically, we analysed how LCZ classes are represented by CWS in 2015, how T varies within each LCZ class ('intra-LCZ variability'), and if significant

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding. (orig.) [German] Vaskulaere Pathologien sind seltene Ursachen fuer den klinischen Zustand eines akuten Abdomens.

    To determine whether physical activity may affect cognitive performance in patients with Parkinson's disease by measuring reaction times in patients participating in the Berlin BIG study. Randomized controlled trial, rater-blinded. Ambulatory care. Patients with mild to moderate Parkinson's disease (N=60) were randomly allocated to 3 treatment arms. Outcome was measured at the termination of training and at follow-up 16 weeks after baseline in 58 patients (completers). Patients received 16 hours of individual Lee Silverman Voice Treatment-BIG training (BIG; duration of treatment, 4wk), 16 hours of group training with Nordic Walking (WALK; duration of treatment, 8wk), or nonsupervised domestic exercise (HOME; duration of instruction, 1hr). Cued reaction time (cRT) and noncued reaction time (nRT). Differences between treatment groups in improvement in reaction times from baseline to intermediate and baseline to follow-up assessments were observed for cRT but not for nRT. Pairwise t test comparisons revealed differences in change in cRT at both measurements between BIG and HOME groups (intermediate: -52ms; 95% confidence interval [CI], -84/-20; P=.002; follow-up: 55ms; CI, -105/-6; P=.030) and between WALK and HOME groups (intermediate: -61ms; CI, -120/-2; P=.042; follow-up: -78ms; CI, -136/-20; P=.010). There was no difference between BIG and WALK groups (intermediate: 9ms; CI, -49/67; P=.742; follow-up: 23ms; CI, -27/72; P=.361). Supervised physical exercise with Lee Silverman Voice Treatment-BIG or Nordic Walking is associated with improvement in cognitive aspects of movement preparation.

    In part IV of the Berlin Deinstitutionalisation Study, we reported a positive change in quality of life for 65 resettled patients one year after discharge. In this part, we investigated changes in a longer follow-up period. A group of 66 patients discharged into supported housing was assessed one and five years after baseline. Quality of life, needs for care, patients' assessment of treatment, re-hospitalisation and characteristics of care were studied in a control-group design. After five years, 61 % of the patients continued to live in highly staffed settings (mean staff-patient-ratio: 1 : 3.5). Eleven percent had moved on to independent living and 16 % had returned into an institutional setting. Standard mortality ratios were 4.4 (all causes of death) and 62.5 (2 suicides only of schizophrenic patients). After one year patients (n = 20) showed a significant increase in satisfaction with their living situation and more social contacts. Over the longer period of time, there were also favourable changes, which failed to reach statistical significance (n = 24). Average length of inpatient stay per year of the illness was decreased significantly at both follow-ups. Interpretation of the findings is difficult because of the small sample size and selection effects. Most of the former long-stay patients appear able to live in the community with a significant decrease of time spent in hospital. Whilst patients were particularly satisfied with their accommodation at one year follow-up, this did not lead to a generalised improvement in subjective quality of life and other subjective criteria in the long term. In line with other recent studies on community mental health care one may conclude that small case loads alone do not have major beneficial effects. Further research should evaluate more systematic and targeted models of mental health care in the community in general and of supported housing in particular.

    Background: Polytrauma patients are expected to have a higher risk of mortality than that obtained by the summation of expected mortality owing to their individual injuries. This study was designed to investigate the outcome of patients with polytrauma, which was defined using the new Berlin definition, as cases with an Abbreviated Injury Scale (AIS) ≥ 3 for two or more different body regions and one or more additional variables from five physiologic parameters (hypotension [systolic blood pressure ≤ 90 mmHg], unconsciousness [Glasgow Coma Scale score ≤ 8], acidosis [base excess ≤ -6.0], coagulopathy [partial thromboplastin time ≥ 40 s or international normalized ratio ≥ 1.4], and age [≥70 years]). Methods: We retrieved detailed data on 369 polytrauma patients and 1260 non-polytrauma patients with an overall Injury Severity Score (ISS) ≥ 18 who were hospitalized between 1 January 2009 and 31 December 2015 for the treatment of all traumatic injuries, from the Trauma Registry System at a level I trauma center. Patients with burn injury or incomplete registered data were excluded. Categorical data were compared with two-sided Fisher exact or Pearson chi-square tests. The unpaired Student t -test and the Mann-Whitney U -test was used to analyze normally distributed continuous data and non-normally distributed data, respectively. Propensity-score matched cohort in a 1:1 ratio was allocated using the NCSS software with logistic regression to evaluate the effect of polytrauma on patient outcomes. Results: The polytrauma patients had a significantly higher ISS than non-polytrauma patients (median (interquartile range Q1-Q3), 29 (22-36) vs. 24 (20-25), respectively; p sex, age, co-morbidity, AIS ≥ 3, and Injury Severity Score (ISS), the polytrauma patients had a significantly higher mortality rate (OR 17.5, 95% CI 4.21-72.76; p definition of polytrauma is feasible and applicable for trauma patients.

    The citrus fruit borer, Ecdytolopha aurantiana (Lima, 1927) (Lepidoptera: Tortricidae), is responsible for major losses to the citrus industry because it causes rot and drop of fruits. The current study aimed to select and characterize Bacillus thuringiensis (Berliner, 1911) strains toxic to E. aurantiana. For this purpose, 47 B. thuringiensis strains were evaluated in selective bioassays using first instar larvae of E. aurantiana. The lethal concentration (LC 50 ) of the most toxic strains was estimated, and the strains were characterized by morphological, biochemical, and molecular methods. Of the 47 strains tested, 10 caused mortality above 85% and showed mean lethal concentrations between 1.05E+7 and 1.54E+8 spores mL -1 . The lowest LC 50 values were obtained for the HD-1 standard strain and the BR145, BR83, BR52, and BR09 strains. The protein profile showed the presence of Cry proteins of 60, 65, 70, 80, and 130 kDa. The molecular characterization showed the presence of cry1, cry2, cry3, and cry11 genes. The morphological analysis identified three different crystalline inclusions: bipyramidal, round, and cuboidal. The cry1 and cry2 genes were the most frequent among the B. thuringiensis strains evaluated and encode Cry proteins toxic to insects of the order Lepidoptera, which agree with the toxicity results obtained by the selective bioassays against E. aurantiana. The results showed four different B. thuringiensis strains toxic to E. aurantiana at the same level as the HD-1 standard strain, and these strains have biotechnological potential for E. aurantiana control through the production of transgenic plants or the formulation of biopesticides.

    Full Text Available Background and Aim: We aimed to validate the Turkish version of Berlin Questionnaire (BQ and developped a BQ-gender (BQ-G form by adding gender component. We aimed to compare the two forms in defining patients with moderate to severe obstructive sleep apnea (OSA in sleep clinics. Methods: Four hundred and eighty five consecutive patients, refered to our sleep clinic for snoring, witnessed apnea and/or excessive daytime sleepiness were enrolled to the study. All patients underwent in-laboratory polysomnography (PSG. Patients with sleep efficiency less than 40% and total sleep time less than 4 hours, chronic anxiolitic/sedative drug usage, respiratory tract infection within past two weeks were excluded from the study. All the patients fulfilled BQ. The test and retest for BQ were applied in 15-day interval in 30 patients. Results: Totally 433 patients were enrolled to the study (285 male, 148 female.The mean age of the patients was 47,5 ± 10.5 (21-79. 180 patients (41.6% had apnea-hypopnea index (AHI ≤ 15, while 253 patients (58,4% had AHI > 15. The κ value was 48–94 and the the truth value was 69-94% for the test-retest procedure. Sensitivity, specificity, negative predictive value (NPV, positive predictive value (PPV, and area under the curve AUC were 84.2%, 31.7%, 48.7%, 63.4%, and 0.579 in order for BQ and 79.9 %, 51.7%, 63.2% , 69.6%, and 0.652 for BQ-G. Conclusion: The results showed that BQ-G is relatively better than BQ in determining moderate to severe OSA in sleep clinics where most of the patients are sleep apneic but both of the tests were found to have insufficient validities in defining moderate to severe OSA in sleep clinics.

    Research suggests that there is a relationship between the health of urban populations and the availability of green and water spaces in their daily environment. In this paper, we analyze the potential intra-urban relationships between children’s health determinants and outcomes and natural areas in Berlin, Germany. In particular, health indicators such as deficits in viso-motoric development in children are related to environmental indicators such as the natural area cover, natural area per capita and distance to natural areas; however, these indicators are also correlated with social determinants of health. The methodological approach used in this study included bivariate and multivariate analyses to explore the relations between health inequalities and social, socio-economic, and land use parameters. The results on a sub-district level indicated that there was a correlation between natural areas and social health determinants, both of which displayed a certain intra-urban spatial pattern. In particular, a lower percentage of natural area cover was correlated with deficits in viso-motoric development. However, results with percentage of natural area cover and per capita natural area with childhood overweight were not conclusive. No significant correlation was found for percentage of natural area cover and overweight, while significant negative correlation values were found between overweight and per capita natural area. This was identified particularly in the districts that had lower social conditions. On the other hand, the districts with the highest social conditions had the comparatively lowest levels of complete measles immunization. This study may facilitate public health work by identifying the urban areas in which the strengthening of health resources and actions should be prioritized and also calls for the inclusion of natural areas among the social health indicators included in intra-urban health inequality tools.

    Full Text Available Atmospheric particle number size distributions of airborne particles (diameter range 10–500 nm were collected over ten weeks at three sites in the vicinity of the A100 urban motorway in Berlin, Germany. The A100 carries about 180 000 vehicles on a weekday. The roadside particle distributions showed a number maximum between 20 and 60 nm clearly related to the motorway emissions. The average total number concentration at roadside was 28 000 cm−3 with a total range of 1200–168 000 cm−3. At distances of 80 and 400 m from the motorway the concentrations decreased to mean levels of 11 000 and 9000 cm−3, respectively. An obstacle-resolving dispersion model was applied to simulate the 3-D flow field and traffic tracer transport in the urban environment around the motorway. By inverse modelling, vehicle emission factors were derived that are representative of a fleet with a relative share of 6% lorry-like vehicles, and driving at a speed of 80 km h−1. Three different calculation approaches were compared, which differ in the choice of the experimental winds driving the flow simulation. The average emission factor per vehicle was 2.1 (±0.2 · 1014 km−1 for particle number and 0.077 (±0.01 · 1014 cm3 km−1 for particle volume. Regression analysis suggested that lorry-like vehicles emit 123 (±28 times more particle number than passenger car-like vehicles, and lorry-like vehicles account for about 91% of particulate number emissions on weekdays. Our work highlights the increasing applicability of 3-D flow models in urban microscale environments and their usefulness for determining traffic emission factors.

    Two design variants have been developed. A wire mesh sensor has two planes consisting of 16 wires each, with a diameter of 0.12 mm. The wires are symmetrically distributed across the diameter. Distance between the two planes is 1.5 mm. Some measuring points are covered in the corners of pipework. Particularly for the pressure surge experiments, a secon design was developed: the ``heavy`` mesh sensor consisting of thin rod-type electrodes made of stainless steel. The rods are lentiform in cross section in order to minimize the hydraulic resistance and the effects on flow processes. Sensors with 8 x 8 measuring points have been made for NW50 as well as sensors with 16 x 16 measuring points for NW100. They are designed for 7 MPa and a maximum of 150 C. They were used to visualize cavitation downstream of a quick stop valve located at the front end of a pipe about 200 m long. [Deutsch] Es wurden zwei Varianten entwickelt. Ein Drahtgittersensor verfuegt ueber zwei Ebenen zu je 16 Draehten mit einem Durchmesser von 0,12 mm. Die Draehte sind gleichmaessig ueber den Durchmesser angeordnet. Der Abstand zwischen den beiden Ebenen betraegt 1,5 mm. In Rohrleitungen werden in den Eckbereichen einige Messpunkte verdeckt. Speziell fuer die in der Arbeit beschriebenen Druckstossexperimente wurde ein zweiter Typ entwickelt: Der `schwere` Gittersensor mit staebchenfoermigen Elektroden aus nichtrostendem Stahl. Die Staebchen besitzen einen linsenfoermigen Querschnitt, um den hydraulischen Widerstand und die Stroemungsbeeinflussung klein zu halten. Es wurden sowohl Sensoren mit 8 x 8 Messpunkten fuer NW50 als auch ein Sensor mit 16 x 16 Messpunkten fuer NW100 hergestellt. Sie sind fuer 7 MPa und max. 150 C ausgelegt. Mit den Sensor wurde die Kavitation hinter einer Schnellschlussklappe visualisert, die sich am Anfang einer ca. 200 m langen Rohrleitung befindet. (orig.)

    The Kurt-Schwabe-Institut fuer Mess- und Sensortechnik (KSI) developed membrane covered amperometric sensors and H{sub 2} sensors based on solid electrolytes for the measurement of the hydrogen concentration dissolved in the liquid phase of biogas facilities. The sensors were tested in a special biogas laboratory facility. The amperometric sensor allows an early detection of an increase of the hydrogen partial pressure within the biogas medium, which could be hazardous for the stability of the fermentation process.

    The paper shows that apart from the risks, the deregulation of the energy sector also offered new chances, which recently materialized in three emerging independent trends, initiating innovative approaches for energy conversion and applications and demand for new knowledge-based, near-production energy services as a new field for engineers: Providers of energy efficiency-related technology widen their capabilities by adding the new business segment of energy service marketing. Industrial energy users more strongly consider outsourcing of energy conversion systems and the relevant contracting schemes as an option for reducing energy costs. Public enterprise as energy users started following this trend, all the more as insufficient financial resources do not permit them to reinvest. The paper discusses the conversion processes which currently open up promising chances for energy service producers. (orig./CB) [Deutsch] Neben Gefahren, die inhaerentes Merkmal der Liberalisierung sind, zeichnen sich drei unabhaengige Entwicklungen ab, die innovative Initiativen in der Energiewandlung und -nutzung staerken und wissensintensive produktionsnahe Dienstleistungen als zentrale Aufgabe fuer den Ingenieur initieren: - Die Energieeffizienz-Technologieanbieter nehmen die Energiedienstleistungen in ihre Angebotspalette auf. - Die betrieblichen Energieanwender beginnen zunehmend, ueber das Outsourcing energiewandelnder Anlagen Energiekosten zu senken. - Die oeffentliche Hand als Energieanwender beginnt aehnlich zu denken, zumal sie infolge der hohen Verschuldung unzureichende finanzielle Mittel fuer Reinvestitionen hat. Hierueber sei kurz berichtet, bevor auf die Techniken eingegangen wird, die sich besonders aus heutiger Sicht fuer Energiedienstleister eignen. (orig./RHM)

    Everyone involved in providing piping systems for gas and water supply in particular, is nowadays challenged by a large and various range of demands. Slogans like quality management, product liability, service provider's obligation of due care, cost reduction, profitability of the enterprises involved etc. confront each other at the most diverse and varying angles of juxtaposition. Where it is necessary to reconcile various interests with differing demands, electronic documentation of all data which serves the purpose of back-tracing should be implemented. Now, the new traceability system creates the necessary preconditions for a regularised and reliable system for standardisation, for piping and fitting manufacturers and for the producers of welding equipment.

    Airborne pollution measurements for the pollutants benzene and soot were carried out at 14 inner-city measuring points, close to traffic, in the Federal State of Brandenburg, using a distribution model for ideal build-up streets (CPB model) and a model assuming missing fringe buildings (Gauss model). The calculated annual mean values were compared with the measured annual mean values. Benzene: The annual mean values calculated with the help of the CPB model diverged from the measured annual mean values by {+-}25%, apart from one exception. Soot: The calculated annual mean values were always lower than the measured annual mean values. Emission-sources not considered in the calculation (tyre abrasion, secondary dust) are assumed to be the main cause for this difference. (orig.) [Deutsch] Es wurden an 14 innerstaedtischen verkehrsnahen Messpunkten im Land Brandenburg mit einem Ausbreitungsmodell fuer ideale Strassenschluchten (CPB-Modell) und einem Modell unter der Annahme fehlender Randbebauung (Gauss-Modell) Immissionsberechnungen fuer die Schadstoffe Benzol und Russ durchgefuehrt. Benzol: Die mittels CPB-Modell berechneten Jahresmittelwerte wichen bis auf eine Ausnahme maximal um {+-}25% von den Jahresmitteln der Messergebnisse ab. Russ: Die berechneten Jahremittel wiesen stets geringere Werte als die Jahresmittelwerte der Messung auf. Als Hauptursache fuer diese Differenz werden Emissionsquellen vermutet, die nicht bei der Berechnung beruecksichtigt wurden (Reifenabrieb, Sekundaerstaub). (orig.)

New diagnostic approaches are outlined which, in addition to failure detection, also enable optimization of the development process chain. At the same time, the depth of diagnosis is improved in order to obtain a multitude of new meta information while driving, which will serve as a basis for installing new services in the vehicle.

    Acculturation is a complex, multidimensional process involving the integration of the traditional norms, values, and lifestyles of a new cultural environment. It is, however, unclear what impact the degree of acculturation has on obstetric outcomes. Data collection was performed in 2011 and 2012 at three obstetric tertiary centers in Berlin, Germany. Standardized interviews (20-30 min.) were performed with support of evaluated questionnaires. The primary collected data were then linked to the perinatal data recorded at the individual clinics provided from the obstetric centers which correspond with the routinely centralized data collected for quality assurance throughout Germany. The questionnaire included questions on sociodemographic, health care, and migrant-related aspects. Migrant women and women with a migration background were assessed using the Frankfurt Acculturation Scale, a one-dimensional measurement tool to assess the degree of acculturation (15 items on language and media usage as well as integration into social networks). In summary, 7100 women were available for the survey (response rate of 89.6%) of which 3765 (53%) had a migration background. The probability of low acculturation is significantly (p relationships between the degree of acculturation and obstetric parameters show no significant differences for prematurity, 5 min.-Apgar values > 7, arterial umbilical cord pH values > 7.00 and admissions to the neonatal unit. In Berlin, among migrant women a low degree of acculturation may have an unfavorable effect on the utilization of pregnancy care provision. However, there were no relevant differences in obstetric outcome parameters in relation to the degree of acculturation within the migrant population of Berlin.

    As part of radiological communication project (RADKOM), two PACS systems of the radiological clinic in the Rudolf Virchow University Clinic in Charlottenburg and Wedding were connected via the Berkom network of the German Post Office. Within the radiology departments, all CT and MRT systems were joined through a local network. The first results have shown that the PACS stations are of value for providing uniformity of diagnosis and for radiological conferences. It is evident, however, that the speed of transfer and the architecture within the PACS system would be of crucial importance for their practicability for radiological conferences. (orig.) [de

    The length of the chromosome ends, telomeres, is widely accepted as a biomarker of aging. However, the dynamic of the relationship between telomere length and hematopoietic parameters in the normal aging process, which is of particular interest with respect to age-related anemia, is not well understood. We have analyzed the relationship between relative leukocyte telomere length (rLTL) and several hematological parameters in the older group of the Berlin Aging Study II (BASE-II) participants. This paper also compares rLTL between both BASE-II age groups (22-37 and 60-83 years). Genomic DNA was extracted from peripheral blood leukocytes of BASE-II participants and used to determine rLTL by a quantitative PCR protocol. Standard methods were used to determine blood parameters, and the WHO criteria were used to identify anemic participants. Telomere length data were available for 444 younger participants (28.4 ± 3.1 years old; 52% women) and 1,460 older participants (68.2 ± 3.7 years old; 49.4% women). rLTL was significantly shorter in BASE-II participants of the older group (p = 3.7 × 10-12) and in women (p = 4.2 × 10-31). rLTL of older men exhibited a statistically significant, positive partial correlation with mean corpuscular hemoglobin (MCH; p = 0.012) and MCH concentration (p = 0.002). While these correlations were only observed in men, the rLTL of older women was negatively correlated with the number of thrombocytes (p = 0.015) in the same type of analysis. Among all older participants, 6% met the criteria to be categorized as 'anemic'; however, there was no association between anemia and rLTL. In the present study, we have detected isolated correlations between rLTL and hematological parameters; however, in all cases, rLTL explained only a small part of the variation of the analyzed parameters. In disagreement with some other studies showing similar data, we interpret the association between rLTL and some of the hematological parameters studied here to be

    Different reasons prevent migrants from obtaining health insurance resulting in their exclusion from regular medical care in Germany. In case of medical emergency, hospitals are obliged by law to provide treatment. In addition, hospitals might get reimbursed for treatment expenses by social welfare authorities. This includes undocumented migrants who should not be reported to the police. However, actual legislation regarding the level of medical intervention, the principles of medical confidentiality and the conditions of reimbursement by the authorities is unclear. Thus, migrants without health insurance may be precluded from receiving urgent medical treatment. A first assessment of hospital health care for migrants without health insurance in three federal states with the intention to identify obstacles in access to in- and out-patient emergency treatment. Electronic mail survey of all non-specialized general hospitals located in the federal states of Niedersachsen (Lower Saxony, n=129), Berlin (n=46) and Hamburg (n=24). Data was anonymized and descriptively analyzed using SPSS statistical software. Rate of questionnaire return was 31.2% (n=62). Almost all hospitals had already encountered migrants without health insurance in their emergency wards (82.3%) including 72.5% undocumented migrants. 76.7% of all hospitals had submitted a subsequent emergency aid proposal to the social welfare authorities. 17.1% of them confirmed that they were reimbursed in most cases. 8.5% of all participating hospitals mostly consult the police in case migrants are not able to provide any means of identification, whereas 43.6% consult the police only in rare cases. 64.5% of all hospitals reported non-reimbursed expenses for 2011 - 2014 ranging from € 4 000 - €1.01 million. RESULTS indicate that the provision of care for people without health care insurance represents an important issue for a majority of the assessed hospitals since they have to take the responsibility for

    Purpose  To evaluate the potential of routine assessment of intracranial translucency (IT) and other posterior brain parameters in the early detection of open spina bifida during the 11 - 14 weeks screening examination. Materials and Methods  This prospective, multicenter longitudinal study was conducted with the participation of 20 certified DEGUM II or III experts in Berlin, Germany, between June 2010 and October 2013. All pregnant women undergoing a first trimester screening were included in the study and in every patient were the IT, brain stem (BS), cisterna magna (CM), BS to occipital bone distance (BSOB) and BS/BSOB ratio measured. All patients with continuing pregnancy underwent a second trimester scan. Our data was used to develop our own reference ranges. The primary outcome parameter was the presence of open spina bifida. Results  A total of 15 526 women with 16 164 fetuses were examined. Median of the IT was 2.1 mm, of the CM 1.6 mm, of the BS 2.7 mm, of the BSOB 5.5 mm, and of the BS/BSOB ratio 0.49. There were 11 cases with open spina bifida (incidence of 6.8/10 000). The detection rate was 100 % and in all cases of spina bifida, the anomaly was detected either at the first examination (n = 8) or considered suspicious and the lesion then detected a few weeks later (n = 3). Considering individual measurements, however, the detection rate was 18 % with the complete absence of the IT and 45 % with cut-off values. For the CM measurement, the detection rate was 64 % with the absence of the CM and 73 % with cut-off values. The other parameters proved not to be predictive of open spina bifida. Conclusion  In the hands of an expert, open spina bifida can be reliably diagnosed early in gestation during the 11 - 14 weeks screening. The measurement of different parameters of the posterior brain, especially the CM and the use of cut-off values are of tremendous benefit in achieving a high sensitivity in the

    The present report contains results on the occurrence of polar and nonpolar substances in the Elbe and selected tributaries which were analysed in the period from 1994 to 1999. It shows that industrial and municipal purification plants still have an insufficient cleaning capacity for certain substances. The process by which ubiquitous pollutants can enter the Elbe via a small, widely ramified fluvial system is exemplified for the family of chloroalkyl phosphates. These mainly occur in flame retardants and plasticisers in polyurethanes. The paper also presents results from a selection of 28 substances listed in Directive 76/464/ECC. They provide a decision aid for the planning of future measuring concepts based on the EU Water Framework Directive. In the ARGE ELBE programme organic pollutants are recorded and published on a routine basis. These are mostly nonpolar substances such as the well-known polychlorinated biphenyls or slow-evaporating insecticidal chlorinated hydrocarbons such as DTT. Recent analysis results show that this group of substances is relevant now as before and that it will remain so for the years to come. Special studies involving aqueous phase measurements were performed on a different group of substances, namely polar substances, which are generally readily soluble. The substances on which this report is chiefly focused originate from different sources: industrial and municipal effluents, diffuse inputs from agriculture and atmospheric depositions. In many cases they are difficultly degradable and could attain significance where river water in the form of river bank filtrate is used for drinking water production. However, due to complex and effective purification technologies they rarely enter drinking water.

    Highlights: • Monitoring study Berlin-2012 confirms tap water contamination with gadolinium. • Contamination confined to western districts of Berlin. • Strong increase of anthropogenic gadolinium from 2009 to 2012. • Anthropogenic gadolinium is tracer for wastewater-derived substances. - Abstract: The distribution of rare earth elements (REE) in tap water sampled in December 2012 in Berlin, Germany, is characterized by anomalously high levels of gadolinium (Gd). While the western districts of the city show strong anthropogenic positive Gd anomalies in REE distribution patterns, the eastern districts are (almost) unaffected. This contamination with anthropogenic Gd results from Gd-based contrast agents used in Magnetic Resonance Imaging, that enter rivers, groundwater and eventually tap water via the clear water effluent from wastewater treatment plants. While the spatial distribution of anthropogenic Gd in 2012 confirms results of an earlier study in 2009 (Kulaksiz and Bau, 2011a), anthropogenic Gd concentrations have increased between 1.5- and 11.5-fold in just three years. This confirms predictions based upon the increase of anthropogenic Gd concentrations in the Havel River over the past two decades and the time it takes the water to migrate from the Havel River to the groundwater production wells. Anomalously high levels of anthropogenic Gd in tap water, which are not confined to Berlin but have also been observed in London, U.K., and in German cities in the Ruhr area and along the Rhine River, reveal that high-technology metals have become emerging contaminants. While non-toxic at the observed concentrations, the anthropogenic Gd is a microcontaminant that may be used as a conservative pseudo-natural tracer for wastewater-derived xenobiotics such as pharmaceuticals, food additives and personal care products. Our results suggest that monitoring the concentrations of such substances in Berlin’s drinking water can be restricted to a few central and

    The Berlin definition of Acute Respiratory Distress Syndrome (ARDS) has been applied to military burns resulting from combat-related trauma, but has not been widely studied among civilian burns. This study's purpose was to use the Berlin definition to determine the incidence of ARDS, and its associated respiratory morbidity, and mortality among civilian burn patients. Retrospective study of burn patients mechanically ventilated for ≥48h at an American Burn Association-verified burn center. The Berlin criteria identified patients with mild, moderate, and severe ARDS. Logistic regression was used to identify variables predictive of moderate to severe ARDS, and mortality. The outcome measures of interest were duration of mechanical ventilation and in-hospital mortality. Values are shown as the median (Q1-Q3). We included 162 subjects [24% female, age 48 (35-60), % total body surface area (TBSA) burn 28 (19-40), % body surface area (BSA) full thickness (FT) burn 13 (0-30), and 62% with inhalation injury]. The incidence of ARDS was 43%. Patients with ARDS had larger %TBSA burns [30.5 (23.1-47.0) vs. 24.8 (17.1-35), p=0.007], larger FT burns [20.5(5.4-35.5) vs. 7 (0-22.1), p=0.001], but had no significant difference in the incidence of inhalation injury (p=0.216), compared to those without ARDS. The % FT burn predicted the development of moderate to severe ARDS [OR 1.034, 95%CI (1.013-1.055), p=0.001]. ARDS developed in the 1st week after burn in 86% of cases. Worsening severity of ARDS was associated with increased days of mechanical ventilation in survivors (p=0.001), a reduction in ventilator-free days/1st 30 days in all subjects (p=0.004), and a strong indication of increased mortality (0% in mild ARDS vs. 50% in severe ARDS, unadjusted p=0.02). Neither moderate ARDS nor severe ARDS were significant predictors of death. ARDS is common among mechanically ventilated civilian burn patients, and develops early after burn. The extent of full thickness burn predicted

    The use of VADs as a BTT in children with heart failure has increased due to enhanced device design and reliability, leading to improved survival, functional capacity, and quality of life. However, the use of VADs in patients with Fontan physiology as a BTT is rare with few case reports. Here, we describe a case of implantation of the Berlin VAD as a BTT for 179 days, one of the longest reported periods of mechanical support, in a child with failing single ventricle. © 2015 John Wiley & Sons A/S.

    In the framework of the International Horticultural Exhibition 1993 in Stuttgart a number of buildings designed by renowned architects was erected under the title `Experimental Living 2000`, which demonstrate the use of innovative techniques. The buildings presented in the present Article, designed by the architects Hegger, Hegger-Luhnen and Schleiff (HHS, Kassel), are three single-family semidetached houses including a south-oriented winter garden extension. The Institut fuer Licht- und Bautechnik had the task to establish an energy concept optimizing the solar and light transmitting properties of the winter garden facade. The rooms are heated and illuminated by the sun. Surplus solar energy which would lead to an overheating and glare is collected by transparent shading elements with hologrammes and is transformed into electricity. In the framework of this project innovative techniques for the use of solar energy were tested and applied, which were developed by the Institut fuer Licht und Bautechnik (ILB) ath the Fachhochschule Koeln unter the direction of Prof. Dr. Gutjahr and Prof. Dr. Mueller. The research project is supported by the Federal Ministry for Research and Technology, by the builderowners (LEG, SWG, SWSG), and by the firms and designers involved. (orig.)

    Full Text Available Background: Berlin Questionnaire (BQ, an English language screening tool for obstructive sleep apnea (OSA in primary care, has been applied in tertiary settings, with variable results. Aims: Development of BQ Portuguese version and evaluation of its utility in a sleep disordered breathing clinic (SDBC. Material and methods: BQ was translated using back translation methodology and prospectively applied, previously to cardiorespiratory sleep study, to 95 consecutive subjects, referred to a SDBC, with OSA suspicion. OSA risk assessment was based on responses in 10 items, organized in 3 categories: snoring and witnessed apneas (category 1, daytime sleepiness (category 2, high blood pressure (HBP/obesity (category 3. Results: In the studied sample, 67.4% were males, with a mean age of 51 ± 13 years. Categories 1, 2 and 3 were positive in 91.6, 24.2 and 66.3%, respectively. BQ identified 68.4% of the patients as being in the high risk group for OSA and the remaining 31.6% in the low risk. BQ sensitivity and specificity were 72.1 and 50%, respectively, for an apnea-hipopnea index (AHI > 5, 82.6 and 44.8% for AHI > 15, 88.4 and 39.1% for AHI > 30. Being in the high risk group for OSA did not infl uence significantly the probability of having the disease (positive likelihood ratio [LR] between 1.44-1.49. Only the items related to snoring loudness, witnessed apneas and HBP/obesity presented a statistically positive association with AHI, with the model constituted by their association presenting a greater discrimination capability, especially for an AHI > 5 (sensitivity 65.2%, specificity 80%, positive LR 3.26. Conclusions: The BQ is not an appropriate screening tool for OSA in a SDBC, although snoring loudness, witnessed apneas, HBP/obesity have demonstrated being significant questionnaire elements in this population.

    Today's urban gardening focuses mainly on vegetable production and rarely includes fruit trees. Health effects of consuming urban crops are questioned due to high local pollution loads. Here, we determined cadmium and lead content in the edible parts of nuts, berries, pome, and stone fruits harvested from fruit trees and shrubs within inner city neighbourhoods of Berlin, Germany. We analysed how local settings at sampling sites shaped the trace metal content. We revealed significant differences in trace metal content depending on species, fruit type, local traffic, and parameters related to barriers between the sampling site and neighbouring roads. Higher overall traffic burden and proximity to roads increased whereas buildings or vegetation as barriers reduced trace metal content in the edible biomass. We demonstrate, that the consumption of non-vegetable fruits growing in inner city sites in Berlin does not pose a risk on human health as long as the fruits are thoroughly washed and it is provided that site pollutions and impacts are considered in garden concepts and guidelines. © 2013 Published by Elsevier Inc.

    The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement's themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities. This document summarises the approaches discussed by medical representatives from the governing bodies of 10 different contact and collision sports in Dublin, Ireland in July 2017.

    Full Text Available This article examines the origins of what for years has been characterized as a European welfare consensus. It asks whether, indeed, there was a convergence of ideas, and if so, what led to it. Based on public health records from governmental, municipal, and international agencies in immediate postwar Europe, but also on sources reflecting public opinion, Allied military government discourses and policies, urban planners, medical professionals, and others, it argues that indeed there was a period in European history which generated something of a postwar convergence of ideas regarding public health and welfare. The postwar period witnessed a remarkable consensus about the importance of public planning, spending, and state involvement in the health and welfare sector. By examining the case of Berlin as one immediate postwar city and situating it in the larger European context of the time, one can point to common motivations and even actors involved. The root of this consensus was not any optimistic humanitarian ideology, nor even only a concern about public health or the spread of epidemics, though the latter was prominent. Equally important, it grew out of a shared setting marked by physical destruction and political instability. As a result, concerns about governability, social order, and political legitimacy came to the forefront, even of health and housing debates. In the case of Berlin, the public health debate was driven furthermore by a fear of the return of National Socialism.

    Using qualitative data via providers' perspectives, the goal of this study was to identify strengths and weaknesses in the current approaches being used to prevent onward transmission of HIV among men who have sex with men (MSM) in Berlin, Germany. In 2013, 18 participants from 10 organizations who provide direct outreach or services to MSM were interviewed (30-75 minutes). With regard to strategies and services that individuals believed contributed to the organization's success, we identified five themes: (1) Having staff and volunteers to "match" the target population, (2) Embracing homosexuality and gay identity, (3) Being invested in the cause, (4) Coordination of services to avoid overlap and duplication, and (5) Seeing eye-to-eye with the target population. Finally, with regard to areas in which organizations felt they could use improvement (i.e., continuing challenges), we identified three themes: (1) Insufficient funding and resources, (2) Insufficient services, and (3) HIV stigma, homophobia, and shifting attitudes about HIV. This study informs HIV prevention approaches in Berlin, Germany as well as other urban centers where MSM are disproportionally affected by the HIV epidemic.

    Directory of Open Access Journals (Sweden)

    Andrew Bank

    Full Text Available This article presents a case for the centrality of race and racism in the training and early ethnographic writings of Werner Eiselen (1899-1977. Together with further discussion in two other articles, it demonstrates that Eiselen was not the consolidator of the British functionalist anthropological tradition in South Africa nor a strong affiliate of the liberal school of African studies in South Africa as other scholars have proposed. On the contrary, he was the founder of a radically different ethnographic tradition: an anti-humanist and deeply racialised tradition of cultural study with its roots in Berlin Mission Society ideology and German Africanist linguistics. I track the origins of Eiselens volkekunde to his missionary background in a former Boer Republic, his Afrikaner nationalist schooling and university career, and especially to his training in African linguistics in Hamburg (and Berlin between 1921 and 1924 under the leading international figure in the field, the German linguist and ethnologist Carl Meinhof (1857-1944, whose racially informed theories and politics profoundly shaped Eiselen and the school of volkekunde that he would father during his decade-long tenure at Stellenbosch University.

    Endocrineously active substances are discharged into surface bodies of water with communal and industrial effluents. Especially estrogenic substances like Bisphenol A, alkyl phenols and alkyl phenol ethoxylates in the Elbe and its tributaries have been neglected so far. In the context of an interdisciplinary project, chemists, biologists and mathematicians investigated the concentrations and fate of these xenoestrogens, relative potential effects of unknown water constituents and quantitative statistical mechanisms based on the available analytical findings. The contribution intends to contribute information on the pollutant situation of selected endocrineously active substances in the Elbe and its tributaries.

The statements and contributions to the closing plenary discussion touched on many aspects of ethics, personal rights, occupational medicine and insurance issues relating to this subject, all of which extend far beyond the purely technical issues of radiation protection. The present volume contains the lecture manuscripts of the meeting as well as a summarising assessment by the Radiation Protection Committee. [German] Der Strahlenschutzkommission war es ein besonderes Anliegen, sich im Rahmen ihrer Klausurtagung am 20./21. Januar 2000 mit der Bedeutung der genetischen Praedisposition und der genetischen Instabilitaet fuer die individuelle Strahlenempfindlichkeit sowie mit den damit moeglicherweise verbundenen Auswirkungen auf den Strahlenschutz intensiv auseinanderzusetzen. Die vielfaeltigen ethischen, persoenlichkeitsrechtlichen, arbeitsmedizinischen und versicherungsrelevanten Aspekte dieser Thematik, die weit ueber rein fachliche Fragen des Strahlenschutzes hinausgehen, kamen waehrend des abschliessenden Podiumsgespraeches in Stellungnahmen und Diskussionsbeitraegen zur Sprache. Der vorliegende Band beinhaltet die Vortragsmanuskripte dieser Veranstaltung sowie eine zusammenfassende Bewertung durch die Strahlenschutzkommission. (orig.)

    Air pollution is the number one environmental cause of premature deaths in Europe. Despite extensive regulations, air pollution remains a challenge, especially in urban areas. For studying summertime air quality in the Berlin-Brandenburg region of Germany, the Weather Research and Forecasting Model with Chemistry (WRF-Chem) is set up and evaluated against meteorological and air quality observations from monitoring stations as well as from a field campaign conducted in 2014. The objective is to assess which resolution and level of detail in the input data is needed for simulating urban background air pollutant concentrations and their spatial distribution in the Berlin-Brandenburg area. The model setup includes three nested domains with horizontal resolutions of 15, 3 and 1 km and anthropogenic emissions from the TNO-MACC III inventory. We use RADM2 chemistry and the MADE/SORGAM aerosol scheme. Three sensitivity simulations are conducted updating input parameters to the single-layer urban canopy model based on structural data for Berlin, specifying land use classes on a sub-grid scale (mosaic option) and downscaling the original emissions to a resolution of ca. 1 km × 1 km for Berlin based on proxy data including traffic density and population density. The results show that the model simulates meteorology well, though urban 2 m temperature and urban wind speeds are biased high and nighttime mixing layer height is biased low in the base run with the settings described above. We show that the simulation of urban meteorology can be improved when specifying the input parameters to the urban model, and to a lesser extent when using the mosaic option. On average, ozone is simulated reasonably well, but maximum daily 8 h mean concentrations are underestimated, which is consistent with the results from previous modelling studies using the RADM2 chemical mechanism. Particulate matter is underestimated, which is partly due to an underestimation of secondary organic aerosols

While the best results achieved so far do not give rise to a noticeable improvement compared to light trapping strategies based on statistical texture, the transferability of the process developed here to other solar cell structures is an important advantage. (ii) Thin microcrystalline SiGe-layers on glass produced by evaporation and laser crystallization exhibit promising electronic and optical properties with respect to applications as absorber layers in thin film solar cells. However, to this end, a further optimization of the crystallization process and the ensuing material properties will be necessary. (orig.) [German] Fuer Duennschicht-Solarzellen ist im Allgemeinen eine integrierte Lichtfallenstruktur notwendig, um eine moeglichst vollstaendige Absorption des Sonnenspektrums zu erzielen. Gegenwaertig werden hierfuer fast ausschliesslich statistisch texturierte transparente Elektrodenschichten (z.B. aus ZnO) eingesetzt. Ziel dieses Projektes war die Herstellung und Untersuchung mikrostrukturierter periodischer Gitterkoppler zur gezielten Einkopplung schwach absorbierten Lichtes. Zusaetzlich sollten erste Versuche zum Einsatz von kristallinen SiGe-Duennschicht-Filmen auf Glas als stark absorbierendes Halbleitermaterial fuer den Einsatz in Tandem-Solarzellen exploratorisch durchgefuehrt werden. Im Rahmen des Forschungsprojektes wurden strukturierte Elektroden aus TCO hergestellt, die hohe optische Transparenz bis ins UV aufweisen. Zur effizienten Lichteinkopplung wurden erfolgreich Beugungsgitter im Submikrometerbereich hergestellt, die als Lichtfallen wirken. In Zusammenarbeit mit dem Institut fuer Photovoltaik (IPV) wurden diese Lichtfallen in Solarzellen integriert. Die elektrischen und optischen Eigenschaften dieser Solarzellen mit Gitterkoppler-Strukturen wurden systematisch untersucht, insbesondere auch hinsichtlich einer durch die Strukturierung bewirkten internen Feldverstaerkung.

    Each tank-container respectively portable tank for multimodal purposes has to be closed and fitted with safety devices (pressure relief devices). Pressure relief devices have to meet essential requirements concerning their total delivery capacity in condition of complete engulfment of the tank in fire. The total capacity of these devices should be sufficient to limit the pressure in the tank in each case to its test pressure, maximally. The total delivery capacity has to be determined by applying a formula which had been developed in the USA and taken over later on into international and national regulations on the transport of dangerous goods. The derivation of this formula will be described and evaluated with regard to given facts related to general thermodynamics and fire test results. (orig.) [German] Wesentliche Anforderung an Sicherheitseinrichtungen (Druckentlastungsvorrichtungen) fuer Tanks und Tankcontainer im multimodalen Verkehr ist, dass diese Einrichtungen im Feuerfall eine Gesamtdurchflussmenge aufweisen muessen, die zumindest einen Druckanstieg ueber den Pruefdruck hinaus verhindert. Die Ermittlung der Gesamtdurchflussmenge erfolgt nach einer in den USA entwickelten, in internationale und nationale Verkehrsvorschriften uebernommenen Zahlenwertgleichung (Kapazitaetsformel). Die Herleitung dieser Zahlenwertgleichung sowohl aus allgemein thermodynamischen als auch empirischen Gegebenheiten wird beschrieben und bewertet. (orig.)

    Breast cancer is in 5% of cases due to a genetic disposition. BRCA1 and BRCA2 are by far the most common breast cancer susceptibility genes. For a woman with a genetic predisposition, the individual risk of developing breast cancer sometime in her life is between 70 and 90%. Compared to the spontaneous forms of breast cancer, woman with a genetic predisposition often develop breast cancer at a much younger age. This is why conventional screening programs on the basis of mammography alone cannot be applied without modification to this high-risk group. In this article, an integrated screening concept for women with genetic prodisposition for breast cancer using breast self-examination, clinical examination, ultrasound, mammography and magnetic resonance imaging is introduced. (orig.) [Deutsch] Mammakarzinome sind in etwa 5% auf eine genetische Disposition zurueckzufuehren. Am haeufigsten finden sich Mutationen im Bereich der Gene BRCA1 und BRCA2. Frauen mit einer genetischen Disposition erkranken in etwa 70-90% im Laufe ihres Lebens an einem Mammakarzinom. Das Erkrankungsalter bei diesen Frauen liegt in der Regel deutlich niedriger als bei den spontanen Formen des Mammakarzinoms, so dass vorhandene Frueherkennungskonzepte auf der Basis eines Mammographiescrennings nicht ohne weiteres auf dieses Hochrisikokollektiv uebertragbar sind. Im folgenden wird ein integriertes Konzept zur Frueherkennung bei Frauen mit genetischer Praedisposition fuer ein Mammakarzinom auf der Basis von Brustselbstuntersuchung, klinischer Untersuchung, Sonographie, Mammographie und Magnetresonanztomographie vorgestellt.

    On New Year's Eve 2002, the world's first commercial Transrapid superspeed maglev train started for its maiden trip in Shanghai and opened a new chapter of railroad history. In the presence of German Chancellor Gerhard Schroeder and Chinese Prime Minister Zhu Rongji on board the train, the Transrapid reached the operating speed of 430 km/h planned for scheduled operation on the 30 kilometres long route between the city center and Pudong International Airport. The constructions of the Shanghai Transrapid line and the decision on the maglev projects in Germany have given a boost to the innovative rail system. (orig.) [German] Mit der Jungfernfahrt auf der weltweit ersten kommerziellen Transrapid-Strecke in Shanghai hat am Silvester-Tag 2002 eine neue Aera des Bahnverkehrs begonnen.

    The autonomous hybrid, which is being developed at the Technical University of Munich in the context of special research area 365, requires a special gearbox which takes into account the different requirements of the two drive sources used in the vehicle. Smooth circumferential gearboxes, whose ratio can be considerably increased with the aid of the i{sup 2} principle, are an interesting possibility. The most favourable arrangement of the i{sup 2} gearbox for the application is determined in the form of a structure variation with subsequent useful value analysis. Gearbox structures used for detailing are introduced by selected design criteria. (orig.) [Deutsch] Der Autarke Hybrid, der im Rahmen des Sonderforschungsbereichs 365 der Deutschen Forschungsgemeinschaft an der Technischen Universitaet Muenchen entwickelt wird, benoetigt ein besonderes Getriebe, das den unterschiedlichen Anforderungen der beiden im Fahrzeug eingesetzten Antriebsquellen Rechnung traegt. Eine interessante Moeglichkeit sind stufenlose Umschlingungsgetriebe, deren Spreizung mit Hilfe des i{sup 2}-Prinzips wesentlich erweitert werden kann. Die fuer den Anwendungsfall guenstigste Anordnung des i{sup 2}-Getriebes wird in Form einer Strukturvariation mit anschliessender Nutzwertanalyse ermittelt. Anhand ausgewaehlter Auslegungskriterien wird die zur Detaillierung herangezogene Getriebestruktur vorgestellt. (orig.)

    Electronic systems to be installed in automobile vehicles often have to be implemented on extremely limited space and are subject to high temperature and acceleration stress. Bosch has fully developed a multi-layer ceramic system as a substrate (Low-Temperature Cofire Ceramic - LTCC) and has so far delivered approx. 70 million LTCC substrates for the most diverse electronic control units. Bosch manufactures the LTCC not only for its in-house production, but also supplies these substrates to other companies. This paper describes the applications and the structure of the LTCC and describes the key aspects of reliability and quality. (orig.)

    The subjects of inter-disciplinary planning and building (architect, builder, firms carrying out the work), facility management and outsourcing of services to external firms have gone beyond the previous literary importance to be incorporated in daily practice for some years now. In this article, based on two concrete examples, it is shown what advantages are produced for the builder, the user and the facility manager, if one moves from the traditional practice of individual craftsmen to early inclusion of a building technology plant producer and his partners on the architectural and building design side in an integrated planning process.

    Does the energy transition keep what it once promised? Five years after the first index survey, the balance sheet is mixed: While key objectives such as the reduction of CO{sub 2} emissions are not achieved, important new tasks are lacking in target marks - such as the decarbonisation of the heating and transport sector or the interplay of central and decentralized supply. The energy transition index addresses these future topics with new indicators and calculation bases. Now it is up to the next federal government to set the right course so that the energy transition becomes a success story. The formulation of less, consistent and clear goals rank first. [German] Haelt die Energiewende, was sie einst versprochen hat? Fuenf Jahre nach der ersten Index-Erhebung faellt die Bilanz gemischt aus: Waehrend zentrale Ziele wie die Reduktion der CO{sub 2}-Emissionen nicht erreicht werden, fehlt es fuer wichtige neue Aufgaben an verbindlichen Zielmarken - etwa zur Dekarbonisierung des Waerme- und Verkehrssektors oder zum Zusammenspiel von zentraler und dezentraler Versorgung. Der Energiewende-Index adressiert diese Zukunftsthemen mit neuen Indikatoren und Berechnungsgrundlagen. Jetzt ist es an der kommenden Bundesregierung, die richtigen Weichen zu stellen, damit die Energiewende zur Erfolgsgeschichte wird. Die Formulierung weniger, konsistenter und klarer Ziele steht dabei an erster Stelle.

    The present thesis deals with the usage of the ion-beam enhanced etching (IBEE) for the 3D structuration of lithium niobate (LiNbO{sub 3}).Hereby the approach of the enhancement of the wet-chemical etching rate due to the irradiation with energetic ions is pursued. This method is very success promising for the realization of micro- and nanostructures with perpendicular structural walls as well as small roughnesses. The aim of this thesis consisted therein to form the foundations for the realization of three-dimensional micro- and nanostructures (for instance: Layer systems and photonic crystals) in LiNbO{sub 3} with high optical quality and to demonstrate on selected examples. Conditions for the success of the IBEE structuration technique is first of all the understanding of the defect formation under ion irradiation as well as the radiation-induced structure changes in the crystal and the change of the chemical resistance connected with this. For this the defect formation was studied in dependence on th ion mass, the ion energy, and the irradiation temperature. Thermally induced influences and effects on the radiation damage, as they can occur in intermediate steps in the complex processing, must be known and were studied by means of subsequent temperature treatment. The results from the defect studies were subsequently applied for the fabrication of micro- and nanostructures in LiNbO{sub 3}. Shown is the realization of lateral structure with nearly perpendicular structure walls as well as the realization of thin membranes and slits. The subsequent combination of lateral structuration with the fabrication of thin membranes and slits allowed the three-dimensional structuration of LiNbO{sub 3}. This is exemplarily shown for a microresonator and for a 2D photonic crystal with below lying air slit.

    In Germany, the smoking prevalence among adolescents is among the highest in Europe. Our aim was to evaluate the long-term effectiveness of a combined student-parent and a student-only smoking prevention programme to reduce the smoking prevalence among 7th grade students in Berlin. Three-armed cluster-randomized controlled trial (RCT). Schools as cluster units were randomized into (i) student intervention, (ii) combined student-parent intervention or (iii) control group, with follow-up after 12 and 24 months. High schools and integrated secondary schools in Berlin, Germany. Seventh grade students aged 11-16 years. We included 47 schools, 161 classes and 2801 students [50.1% girls, mean age ± standard deviation (SD) = 13.0 ± 0.6 years]. The primary outcome was self-reported regular smoking (at least one cigarette per day) after 24 months (point prevalence). Further self-reported outcomes were other smoking behaviours as well as parental rules and attitudes towards smoking. Comparisons were calculated as odds ratios (OR) with 95% confidence intervals (CI). At baseline, 2.3% of the students reported that they smoked regularly. After 24 months, 7.8% and 7.0% were regular smokers in the student-only intervention and the student-parent intervention, respectively, compared with 10.1% in the control group. The OR for being a regular smoker was 0.81 (0.34-1.92) for the student-parent intervention versus control, 0.95 (CI = 0.41-2.22) for the student-only intervention versus control and 0.85 (0.38-1.89) for student-parent intervention versus student-only intervention. A combined student-parent smoking prevention intervention delivered via secondary schools in Berlin, Germany did not result in a statistically significant reduction in regular smoking compared with a control group or a student-only intervention. The student-only intervention did not result in a significant reduction in regular smoking compared with the control group. © 2016 Society for the Study

    The aim of this thesis is to show marketing possibilities for fermentation products and to generate sepcific recommendations for potential producers and marketers of fermentation products. Since the marketing of fermenting products is largely unexplored and a research gap, this project was launched with an exploratory phase. After the exploratory phase, private gardeners were identified as a promising customer group. Knowledge about the preferences of private gardeners when purchasing soil and fertilizer are crucial for the market success of processed fermentation products. In order to fathom the decision-making behavior of this potential customer group, personal interviews were conducted with private gardeners. These results enable potential producers and marketers of fermentation products to create a product that is in demand on the market because it meets the needs of potential consumers. The personal preferences, however, can be very different, for which reason a segmentation into different groups with similar preferences is made. [German] Ziel dieser Arbeit ist es, Vermarktungsmoeglichkeiten fuer Gaerprodukte aufzuzeigen und konkrete Empfehlungen fuer potenzielle Hersteller und Vermarkter von Gaerprodukten zu generieren. Da die Vermarktung von Gaerprodukten weitestgehend unerforscht ist und eine Forschungsluecke darstellt, wurde dieses Vorhaben mit einer explorativen Phase gestartet. Nach der explorativen Phase wurden Privatgaertner als vielversprechende Kundengruppe identifiziert. Kenntnisse ueber die Praeferenzen von Privatgaertnern beim Kauf von Erden und Duengern sind entscheidend fuer den Markterfolg von aufbereiteten Gaerprodukten. Um das Entscheidungsverhalten dieser potenziellen Kundengruppe naeher zu ergruenden, wurden persoenliche Interviews mit Privatgaertnern durchgefuehrt. Diese Ergebnisse ermoeglichen es potenziellen Herstellern und Vermarktern von Gaerprodukten ein Produkt zu kreieren, das auf dem Markt nachgefragt wird, da es den Wuenschen der

    In August 1979, the German Risk Study was presented to the public by the Federal Minister of Research and Technology. The main contractor to prepare the German Risk Study is the Gesellschaft fuer Reaktorsicherheit (GRS). The objective of the Study is to investigate the collective risk involved in accidents at nuclear power plants. The essential results and statements of the Study are comprised in a Summary submitted to the public in August 1979, too. In September 1979, the 'Bremer Arbeits- und Umweltschutz-Zentrum' ('BAUZ') published a 'Stellungnahme zur 'deutschen Risikostudie' der Gesellschaft fuer Reaktorsicherheit (GRS)' (Review of the German Risk Study of the Gesellschaft fuer Reaktorsicherheit), dealing only with the summary of this study, however. The BAUZ review is extremely critical of the German Risk Study and ends in condemning the peaceful utilization of nuclear energy as well as the competent authorities. The GRS review critique in hand scrutinizes the BAUZ paper according to the run of the text. Deliberately, one has renounced a comment in such cases where the reproaches slip in the political or ideological field. The object of the BAUZ review as well as of the GRS critique is the matter to be investigated, aim and methods of the investigations and the results of the German Risk Study. The revision of the review acknowledges that in some cases the tendency of criticism is justified. Often, however, the critique is only a sharpened repetition of what the GRS itself has identified as restrictions of accuracy and inherent significance of the results. In most items, however, the critique is rejected as to be wrong or not proof. (orig./HP) [de

    The buildings of the Mercedes-Benz technology centre at Sindelfingen are equipped with natural illumination and natural ventilation systems. This is achieved by daylighting and by circulation of fresh air. Temperature differences in the air flow are used for keeping a constant temperature level inside the buildings. [Deutsch] Im Technologie-Zentrum in Sindelfingen klimatisiert und beleuchtet Daimler-Benz die Gebaeude weitgehend auf eine natuerliche Art und Weise.

    Posttreatment imaging of primary bone tumours represents a diagnostic challenge for radiologists. Depending on the primary bone tumour common radiological procedures, such as radiography, computed tomography (CT), and magnetic resonance imaging (MRI), are employed. Radiography and CT are particularly useful in benign bone tumours and in matrix-forming bone tumours. MRI comes into consideration with malignant tumour recurrence and tumoral soft tissue infiltration. Bone scintigraphy is of superior importance if a primarily multifocal manifestation of bone tumour or metastasizing tumour disease is suspected. Molecular imaging (FDG-PET and hybrid imaging, using CT) are gaining increasing importance in light of monitoring neoadjuvant chemotherapy and detecting recurrent tumour appearance. The current literature shows sensitivity and specificity values for recurrent detection of up to 92% and 93%. Diagnostic accuracy is as high as 95%, thus, exceeding accuracy values for CT (67%) and MRI (86%) by far. Likewise, this is also applicable for the assessment of the neoadjuvant chemotherapy. Moreover, PET-based modalities are able to establish prognostic statements using SUV-threshold values at baseline (especially for Ewing sarcomas). Advanced imaging techniques have made a great diagnostic step forward and have proven to be relevant and reproducible with respect to both relapse detection and treatment assessment. Furthermore, it is not clear whether a higher detection rate of early tumour recurrence will inevitably lead to better outcome and survival. (orig.) [German] Die posttherapeutische Bildgebung primaerer Knochentumoren stellt eine diagnostische Herausforderung fuer jeden Radiologen dar.

    The reorientation of energy policy is a key issue. The Council of Environmental Experts considers the further use of atomic energy to be irresponsible and recommends a new orientation. Recommendations are made on ecology-centered taxation. Critical comments are made in the context of conservation of nature, where many species of plants and animals still continue to be endangered. The conservation programme of the Federal government, which also comprises a system of large, interconnected biotopes on 10% of Germany's total surface, is approved, and the potential contribution of sustainable agricultural and forestry policy is discussed in a separate chapter. Further subjects discussed are recycling and waste management, protection of water and soil, air pollution abatement, health protection and genetic engineering. The environmental aspects of Eastern European states becoming EC members are gone into in particular. The network of Europen Environmental Councils, for which the German Council of Environmental Experts currently acts as a coordinator, makes intensive efforts to improve environmental counselling in these states. [German] Eines der Schwerpunktthemen des Umweltgutachtens ist die Neuordnung der Energiepolitik.

    This article is a report of the 8th Berlin Workshop on Developmental Toxicity held in May 2014. The main aim of the workshop was the continuing harmonization of terminology and innovations for methodologies used in the assessment of embryo- and fetotoxic findings. The following main topics were discussed: harmonized categorization of external, skeletal, visceral and materno-fetal findings into malformations, variations and grey zone anomalies, aspects of developmental anomalies in humans and laboratory animals, and innovations for new methodologies in developmental toxicology. The application of Version 2 terminology in the DevTox database was considered as a useful improvement in the categorization of developmental anomalies. Participants concluded that initiation of a project for comparative assessments of developmental anomalies in humans and laboratory animals could support regulatory risk assessment and university-based training. Improvement of new methodological approaches for alternatives to animal testing should be triggered for a better understanding of developmental outcomes. Copyright © 2015. Published by Elsevier Inc.

    Full Text Available Crocodylian material from late Pleistocene localities around Antsirabe, Madagascar, stored in the collection of the Museum für Naturkunde, Berlin, was surveyed. Several skeletal elements, including skull bones, vertebrae, ribs, osteoderms, and limb bones from at least three large individuals could be unambiguously assigned to the genus Voay Brochu, 2007. Furthermore, the simultaneous occurrence of Voay robustus Grandidier & Vaillant, 1872 and Crocodylus niloticus Laurenti, 1768 in Madagascar is discussed. Voay robustus and Crocodylus niloticus are systematically separate but similar in stature and size, which would make them direct rivals for ecological resources. Our hypothesis on the extinction of the species Voay, which was endemic to Madagascar, suggests that C. niloticus invaded Madagascar only after V. robustus became extinct. doi:10.1002/mmng.200800007

    Health effects by consuming urban garden products are discussed controversially due to high urban pollution loads. We sampled wild edible mushrooms of different habitats and commercial mushroom cultivars exposed to high traffic areas within Berlin, Germany. We determined the content of cadmium and lead in the fruiting bodies and analysed how the local setting shaped the concentration patterns. EU standards for cultivated mushrooms were exceeded by 86% of the wild mushroom samples for lead and by 54% for cadmium but not by mushroom cultures. We revealed significant differences in trace metal content depending on species, trophic status, habitat and local traffic burden. Higher overall traffic burden increased trace metal content in the biomass of wild mushrooms, whereas cultivated mushrooms exposed to inner city high traffic areas had significantly lower trace metal contents. Based on these we discuss the consequences for the consumption of mushrooms originating from urban areas. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Food production by urban dwellers is of growing importance in developing and developed countries. Urban horticulture is associated with health risks as crops in urban settings are generally exposed to higher levels of pollutants than those in rural areas. We determined the concentration of trace metals in the biomass of different horticultural crops grown in the inner city of Berlin, Germany, and analysed how the local setting shaped the concentration patterns. We revealed significant differences in trace metal concentrations depending on local traffic, crop species, planting style and building structures, but not on vegetable type. Higher overall traffic burden increased trace metal content in the biomass. The presence of buildings and large masses of vegetation as barriers between crops and roads reduced trace metal content in the biomass. Based on this we discuss consequences for urban horticulture, risk assessment, and planting and monitoring guidelines for cultivation and consumption of crops. Copyright © 2012 Elsevier Ltd.

    Full Text Available Participation in planning is a logical consequence of the democratisation of society due to the social and cultural changes related to modernism. Anarchistic participation, as in Autogestion, within a development process, is a critical utopian alternative draft to existing power structures. The participatory turn represented by the International Building Exhibition Berlin 1987 (IBA meant the institutionalisation of these utopian ideas, resulting in a heterotopian notion of participation instrumentalised by governing and economic forces.The most important aspect to our argument is that participation is a matter of critique – with critique as the very core of the modern understanding of progress – and thus enabling forms of improvement in planning, regulating and governing with architectural and urbanistic means. Those means simply embody a specific form of resisting critique and certain shifts in the structures of governing revealing an infrastructural critique which both re-forms the elements and the relations of what is to be resisted.

    The PVS simulation program for Windows was to be extended to the development and simulation of PV-supported equipment and small systems. The following new functions were to be integrated: a) Simulation and dimensioning of indoor power supply of systems with different light sources and independent outdoor systems. b)Integration of small wind generators in the simulation and dimensioning of isolated autonomous systems, including wind data and a component database for small wind turbines; c) Differentiation of the PVS battery model for different battery types (lead, Ni/Cd, Li etc.), optimized operating strategies and flexible dimensioning including an additional component database for battery types; d) Extensive cost analysis for PV-supported appliances and small systems, from investments to consumption, operation and maintenance. This will facilitate investment decisions and help systems of this type along in the market. All program components were designed for high flexibility. Users should be able to vary as many parameters as possible, and to generate and modify their own records. The current project focused on the user interface, i.e. input, data processing, and output. Parallel to this, the Fraunhofer ISE Institute worked on modifications of the computer hardware.

    High prevalence of prostate cancer with multifocality and biological heterogeneity. Insufficient conventional urological diagnostics. Discrimination between significant and insignificant cancer needed. Digital rectal examination, prostate-specific antigen (PSA) serum level, systematic transrectal ultrasound (TRUS)-guided prostate biopsy. Multiparametric magnetic resonance imaging (mpMRI) including T2-weighted (T2w), diffusion-weighted and dynamic contrast-enhanced MRI according to the prostate imaging reporting and data system (PIRADS), MR-targeted biopsy, most frequently MR/TRUS image fusion biopsy. Prostate cancer is characterized by low signal intensity on T2w MRI, restricted water diffusion and pronounced and early uptake of contrast enhancement. Sensitivity and specificity according to the current literature are ca. 80% and 90%, respectively. In cases of suspected prostate cancer, most accurate are mpMRI according to PIRADS and in cases of positive findings, MRI-targeted biopsy, most frequently as MRI/TRUS image fusion biopsy. (orig.)

    There is hardly another area of physics which has a comparable multiplicity of phenomena, like flow in multi-phase mixtures. The wishes of experimenters regarding measurement technique are correspondingly great: Apart from the conventional parameters of pressure, temperature and speed of flow, as great a collection with resolution of the instantaneous phase distribution is required. Also, the phases themselves frequently consists of several components, whose concentration should also be measured. The enormous progress which has recently been made with laser optics and tomographic processes, must be compared with a long list of unsolved problems, above all where non-contact measurement is concerned. The attempts at solutions are multifarious, the need for the exchange of experience is great and the comparson of measurement processes with one another must be strengthened. The workshop has set itself these targets. (orig.) [Deutsch] Es gibt kaum ein anderes Gebiet der Physik, das eine vergleichbare Vielfalt der Erscheinungen aufweist wie Stroemungen von Mehrphasengemischen. Entsprechend gross sind die Wuensche der Experimentatoren hinsichtlich der Messtechnik: Neben den klassischen Parametern Druck, Temperatur und Stroemungsgeschwindigkeit wird eine moeglichst hoch aufloesende Erfassung der momentanen Phasenverteilung benoetigt. Ausserdem bestehen die Phasen selbst haeufig aus mehreren Komponenten, deren Konzentration ebenfalls gemessen werden soll. Den enormen Fortschritten, ie mit laseroptischen und tomographischen Verfahren in letzter Zeit gemacht wurden, steht nach wie vor eine lange Liste bisher ungeloester Aufgaben gegenueber, vor allen Dingen, wenn beruehrungslos gemessen werden soll. Die Loesungsansaetze sind vielfaeltig, der Bedarf an Erfahrungsaustausch ist gross, der Vergleich der Messverfahren untereinander muss verstaerkt werden. Diesen Zielen hatte sich der Workshop ``Messtechnik fuer tationaere und transiente Mehrphasenstroemungen`` verschrieben.

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

    Biological waste water treatment requires biologically readily degradable carbon in order to permit elimination of as much nitrogen as possible. Often now this type of carbon is no longer present in waste water in an appropriate quantity, so that external carbon must be added. Apart from industrially fabricated substrates, the use of industrial residues and waste products as well as of partial waste water streams with a high organic pollutant load is lately being considered for cost reasons. But this is not altogether harmless. Those partial streams may contain substances that inhibit denitrification, impose an additional burden on subsequent cleaning stages or may even pass them unmodified, so that they are emitted into the environment and pose an ecological hazard potential. Hence, industrial residual products need to be specifically selected for use as an external carbon source in denitrification. A suitable strategy is described and demonstrated by means of different examples. (orig.) [German] In der biologischen Abwasserbehandlung ist fuer eine weitestgehende Stickstoffelimination oftmals biologisch gut abbaubarer Kohlenstoff im Abwasser nicht (mehr) in ausreichendem Masse vorhanden. Dann ist die Zugabe einer sog. externen Kohlenstoffquelle erforderlich. Neben industriell hergestellten Substraten wird in letzter Zeit aus Kostengruenden vielfach der Einsatz industrieller Rest- und Abfallstoffe sowie organisch hochbelasteter Abwasserteilstroeme erwogen. Dies ist jedoch nicht unproblematisch, da in diesen Stoffstroemen auch Substanzen enthalten sein koennen, die die Denitrifikation hemmen, nachfolgende Reinigungsstufen zusaetzlich belasten oder diese sogar unveraendert passsieren, dadurch in die Umwelt emittiert werden und damit moeglicherweise aus oekologischer Sicht ein Gefahrenpotential darstellen koennen. Es muss also eine besondere Auswahl der Pruefung industrieller Reststoffe im Hinblick auf den Einsatz als externe Kohlenstoffquelle in der Denitrifikation

    detect pneumonia in patients. (orig.) [German] Zielsetzung: Eine experimentelle Studie zur Untersuchung des Signalverhaltens artifizieller alveolaerer Infiltrate mit T{sub 1}- und T{sub 2}-gewichteten MR-Sequenzen. Material und Methoden: 10 Lungen-Explantate von Schweinen wurden tracheal intubiert, in der kuenstlichen Thoraxhoehle eines Phantoms durch Unterdruck entfaltet und an einem klinischen Magnetresonanztomographen bei 1,5 T untersucht. Mit gezielter Instillation von 100-200 ml Gelatineloesung wurden alveolaere Infiltrate erzeugt und mit Gradientenecho- (2D-, 3D-GRE) und schnellen Spinechosequenzen (T{sub 2}-TSE, T{sub 2}-HASTE) dargestellt. Die Signalintensitaet des Lungenparenchyms nativ und mit Infiltrat wurde an repraesentativen Querschnitten erfasst. Zum Vergleich erfolgten Kontrollen mit Spiral-CT. Ergebnisse: Die instillierte Fluessigkeit simulierte alveolaere Infiltrate mit typischem Milchglasmuster im CT, wie es an Patienten mit Pneumonie oder ARDS beobachtet wird. Vor dem Versuch zeigten nur T{sub 2}-HASTE und T{sub 2}-TSE ein Lungenparenchymsignal (Signal/Rausch-Verhaeltnis von 3,62 bzw. 1,39). Nach Instillation von Fluessigkeit fand sich in diesen Sequenzen ein Signalanstieg von ca. 30% bei 100 ml (p<0,01) bzw. 60% bei 200 ml (p<0,01). Bei 2D-GRE betrug die Signalintensitaetszunahme 0,74% (p=0,32) nach 100 ml und 5,6% (p<0,01) nach 200 ml (fuer 3D-GRE 2,2% [p=0,02] bzw. 4,4% [p<0,01]). Die CT-Kontrollen zeigten fuer 100 ml eine Dichtezunahme um durchschnittlich 17 H.E. (p=0,02) und fuer 200 ml um 75 H.E. (p<0,01). Schlussfolgerungen: Mit T{sub 2}-gewichteten Sequenzen ist die MRT zur Darstellung artifizieller alveolaerer Infiltrate geeignet. (orig.)

Kennzeichnend ist bei der Foerderung eine Konzentration von ueber 60% auf drei Laender bei der Steinkohle und von ca. 40% bei der Braunkohle mit Deutschland an erster Stelle. Die weltweiten Mergers und Acquisitions grosser Bergbaugesellschaften hat auch bei der Kohle zu einer Fokussierung des Lagerstaettenbesitzes und der Foerderanteile gefuehrt. Abgesehen von den staatlich kontrollierten Kohlegesellschften vereinigen die drei groessten privaten Kohlegesellschaften fast 1/4 der Kohlefoerderung auf sich. Die deutsche RAG Coal International befindet sich darunter. Fuer die deutsche Versorgung spielen die Importe eine zunehmende Rolle bei gleichzeitig sinkender einheimischer Foerderung. (orig.)

    Aluminium-tin alloys have been well-known for a long time and have proved to be suitable bearing materials for crankshaft bearings for many years. The known alloy AlZn4,5SiCuPb is one of the aluminium materials capable of sustaining the highest mechanical loads. In order to achieve optimum sliding properties, it would be necessary to increase the share of the soft lead phase in the alloy. This article by KS Gleitlager GmbH shows a reasonably priced manufacturing technology for high-performance aluminium-zinc-silicon-copper alloys. (orig.)

    It was the aim of this project to find indicators within the forest ecosystem for pollution with artificial radionuclides. In the first line, the reference nuclide Cs-137 was examined. These biological indicators could be used quickly and comprehensively for analysis in the case of a possible repeated large-area contamination. In addition to mosses, lichens, ferns, various grasses, spruce needles, bark and wood, in particular bilberrry shrubs (Vaccinium myrtillus) were sampled repeatedly. The bilberry offers itself as a possible indicator plant (high incidence in the entire Austrian federal territory, simple sampling, deer feeding plant) and is also important as forest fruit for humans. (orig./EF) [Deutsch] Ziel dieses Projektes war es u.a., innerhalb des Waldoekosystems Indikatoren fuer die Belastung mit kuenstlichen Radionukliden (in erster Linie wurde das Leitnuklid Cs-137 untersucht) zu finden. Diese Bioindikatoren koennten bei einer etwaigen neuerlichen grossraeumigen Kontamination flaechendeckend rasch zur Analyse herangezogen werden. Neben Moosen, Flechten, Farnen, diversen Graesern, Fichtennadeln, Rinde und Holz wurden insbesondere Heidelbeerstauden (Vaccinium myrtillus) sehr zahlreich beprobt, da sich die Heidelbeeren als moegliche Indikatorpflanzen anbieten (hoher Verbreitungsgrad im gesamten oesterreichischen Bundesbebiet, einfache Probenahme, Aesungspflanzen) und auch als Waldfruechte fuer den Menschen von Bedeutung sind.

    A photovoltaic medical refrigerating set for temperatures in the range of 0 C to +8 C and for eutectic-storage energy supply during sunless periods was developed. WHO field studies showed that photovoltaic refrigerators mainly fail due to battery and battery controller breakdowns. Preliminary tests revealed that the electrochemical batteries of photovoltaic refrigerators can be replaced by thermal cold-storage cells with suitable eutectic media. The total cost of energy storage can be reduced, and simpler designs can be chosen for the controlling elements and actuators. The project under review investigates storage materials, suitable geometrical arrangements in the insulating container, control response under realistic solar radiation conditions, and the verification of all parameters by measurement. A prototype was tested in a climatic cabinet applying WHO standards. (orig.) [Deutsch] Ein photovoltaisch betriebenes medizinisches Kuehlaggregat mit Temperaturen zwischen 0 C bis +8 C soll entwickelt werden, wobei die benoetigte Energie fuer sonnenlose Zeiten ueber Eutektikspeicher bereitgestellt wird.

Vorversuche haben verdeutlicht, dass elektrochemische Batterien bei PV-Kuehlgeraeten durch thermische `Kaelte`-Speicher mit geeigneten Eutektika ersetzt werden koennen. Die Gesamtkosten fuer die Energiespeicherung koennen gesenkt werden. Die Regel- und Stellglieder koennen vereinfacht werden.

    Applied geology is employed in mining geology, raw materials geology, engineering geology, and hydrogeology, of which the two last-mentioned are the most important for the Department of Applied Geology. This series of publications arose from the need of making research findings, dissertations, theses and conference papers accessible to the public faster and more comprehensively than in national and international journals. [Deutsch] Die Aufgaben der angewandten Geologie sind im weitesten Sinne in der Montangeologie, in der Rohstoffgeologie, in der Ingenieurgeologie und in der Hydrogeologie zu sehen.

Wenn wir daraus noch die Umweltgeologie ableiten, so ist der Lehr- und Forschungsschwerpunkt auch des Karlsruher Lehrstuhles fuer Angewandte Geologie (AGK=Angewandte Geologie Karlsruhe) umrissen. Die vorliegende Schriftenreihe ist aus der Notwendigkeit entstanden, Forschungsergebnisse, Dissertationen und ausgewaehlte Diplomarbeiten sowie Beitraege einschlaegiger Tagungen in Karlsruhe rascher und u.U. umfangreicher als in internationalen oder nationalen Journalen moeglich zu publizieren.

    The present project involved extensive studies on the air pollution situation and interactions between organic as well as inorganic air pollutant levels and the vegetation in three east German states. Seven monitoring sites with different emission profiles were selected in Saxony-Anhalt, one typically polluted site in Saxony, and two less polluted sites in Mecklenburg-Western Pomerania. The following emitter types were found to exhibit consistent pollutant patterns: landfills receiving chloroorganic special wastes; hard-coal-fuelled firing installations; commercial charcoal plants; industry; industry - car traffic - domestic fuel combustion; car traffic. [Deutsch] Im Verlauf der Projektarbeiten wurden an sieben durch unterschiedliche Emittententypen belasteten Standorten in Sachsen-Anhalt, einem typisch belasteten Standort in Sachsen und an zwei weniger belasteten Standorten in Mecklenburg/Vorpommern umfangreiche Untersuchungen zur Immissionssituation und der Wechselwirkung der luftgetragenen anorganischen und organischen Schadstofffracht mit der Vegetation durchgefuehrt. Dabei konnten fuer folgende Emittenten charakteristische Schadstoffmuster ermittelt werden: - Deponien mit chlororganischem Sondermuell - Feuerungsanlagen fuer Steinkohle - Gewerbliche Anlagen zur Herstellung von Holzkohle - Industrie - Industrie/Kfz-Verkehr/Hausbrand - Kfz-Verkehr.

    Wastewater with high ammonia concentration is produced by many industries. However, the removal of higher loaded industrial effluents still poses many questions. Dynamic modelling is helpful to understand the process of nitrification and to investigate algorithms of process control. Therefore, a dynamic model of nitrification in completely mixed reactors is proposed based on mass balances for the components ammonia, nitrite, nitrate, dissolved oxygen, carbon dioxide, pH, nitrosomonas and nitrobacter. The biological reaction rates consider oxygen limitation and substrate inhibition. The process model presented it tested by lab scale experiments using an aerated stirred tank reactor. (orig.) [Deutsch] Es wird ein mathematisches Prozessmodell fuer die Nitrifikation von Industrieabwaessern mit hoher Ammoniumkonzentration vorgestellt, das bislang vernachlaessigte Phaenomene wie z.B. Substratueberschusshemmung und Sauerstofflimitierung beruecksichtigt. Als theoretische Grundlage dienen Bilanzgleichungen fuer insgesamt acht Komponenten. Das Simulationsmodell wird durch den Vergleich mit experimentellen Ergebnissen aus einer Laborversuchsanlage auf seine Richtigkeit ueberprueft. In dem Beitrag werden auf diesem Modell basierende Anwendungsbeispiele behandelt. So werden die Moeglichkeiten der dynamischen Prozesssimulation zur Steigerung der Betriebsstabilitaet bei schwankenden Zulaufkonzentrationen und -volumenstroemen gezeigt. Darueber hinaus gelingt die Rekonstruktion der Umsatzraten r(O{sub 2}) und r(NH{sub 3}) aus der Sauerstoff- und Kohlendioxidkonzentration in der Abluft. (orig.)

    The currently existing satellite navigation systems GPS and GLONASS have impressively demonstrated the possibilities of using satellite navigation; there are numerous civilian applications worldwide. However, both systems are controlled nationally and designed for military applications and cannot meet the basic requirements in terms of continuity, integrity and precision required for safety-relevant and sovereign applications. Therefore, the Federal Republic of Germany supports the activities initiated by the EU, which consist of - developing, first of all, technical augmentations to make the existing systems useable without delay also for applications involving exacting requirements (GNSS 1, EGNOS), - carrying out in parallel the definition phase for the development of a global, civilian satellite navigation system (GNSS 2, Galileo). (orig.) [German] Die bisher existierenden Satellitennavigationssysteme GPS und GLONASS haben die Einsatzmoeglichkeiten der Satellitennavigation in eindrucksvoller Weise demonstriert; weltweit haben sich zahlreiche zivile Anwendungen ergeben. Jedoch sind beide Systeme national kontrolliert, auf militaerische Anwendungen zugeschnitten und koennen die fuer sicherheitsrelevante und hoheitliche Anwendungen notwendigen Grundanforderungen nach Kontinuitaet, Integritaet und Praezision nicht garantieren. Daher unterstuetzt die Bundesrepublik Deutschland die von der EU eingeleiteten Aktivitaeten, die daraus bestehen - zunaechst die bestehenden Systeme durch technische Ergaenzungen kurzfristig auch fuer hohe Anforderungen stellende Anwendungen nutzbar zu machen (GNSS 1, EGNOS) - parallel dazu die Definitionsphase zum Aufbau eines globalen zivilen Satellitennavigationssystems (GNSS 2, GALILEO) durchzufuehren.

    Within the research project 'Ueberpruefung und Fortentwicklung der Bodenwerte fuer den Boden-Pflanzen-Pfad', transfer factors soil to plant were calculated for compounds of the substance classes PCB and PAH. Literature studies, experiments undertaken by the LUA/Essen at the lysimeter research station Waldfeucht, and model simulations were used. The transfer differs for the plant species. For kale and wheat straw, the dominant uptake is from air. For lettuce and spinach, a significant uptake from soil was found. The main transport seems to occur via soil resuspension and volatilization, followed by sorption to leaf surfaces. These processes act mainly on low growing harvest products. Uptake from the soil solution and translocation within the plant do not seem to play a role except for phenanthren. The carrots and potatoes investigated showed only a contamination of the peel. The transfer factors of the PCB were throughout higher than that of the PAH. We assume that photolytic processes of PAH on plant surfaces are responsible. Furthermore, there are hints in literature that the metabolism of PAH in plants is faster than that of the PCB. (orig.) [German] Im Rahmen des Forschungsvorhabens 'Ueberpruefung und Fortentwicklung der Bodenwerte fuer den Boden-Pflanze-Pfad' wurden fuer organische Schadstoffe aus den Stoffklassen PCB und PAK Transferfaktoren Boden-Pflanze errechnet. Hierzu wurden Literaturstudien, Experimente der LUA von der Lysimeteranlage Waldfeucht sowie Modellsimulationen eingesetzt. Der Transfer ist fuer die untersuchten Pflanzen nicht einheitlich. Fuer Gruenkohl und Weizenstroh wurde eine Dominanz des Eintrags aus der Luft festgestellt. Demgegenueber zeigte sich fuer Salatpflanzen und Spinat deutliche Aufnahme aus dem Boden. Als Haupttransportweg werden Resuspension von Bodenpartikeln und Ausgasung aus dem Boden mit nachfolgender Sorption an Blattflaechen vermutet. Diese Prozesse wirken vorwiegend auf niedrig wirkende Ernteprodukte

    von ionengestuetzten Depositionsverfahren ohne zusaetzliche Substratheizung fuer Anwendungen in der Gebrauchs-, Praezisions- und Laseroptik. Dazu wurden neuentwickelte Ionenquellen eingesetzt, die Ionen im Energiebereich bis 100 eV erzeugen. Ausgangspunkt fuer die Prozessentwicklung sind grundlegende Arbeiten zum ionengestuetzten Verdampfen von fluoridischen und oxidischen Schichtmaterialien. Die Optimierung der Beschichtungsprozessserien wird in erster Linie mit Hilfe von optischen Charakterisierungsmethoden (Spektralphotometrie, Laserkalorimetrie, Streulichtmessung) durchgefuehrt. Bei den Fluoriden werden Preferential Sputtering-Effekte, die mit Absorptionsverlusten infolge von Fehlstoechiometrien verbunden sind, durch Verwendung niederenergetischer Xenon-Ionen deutlich minimiert. Die Eigenschaften ionengestuetzter Oxidschichten koennen mit Hilfe des Energieeintrags der Ionen pro kondensierendem Schichtteilchen skaliert werden. Der Brechungsindex und die Packungsdichte der untersuchten Oxidmaterialien steigt mit diesem Energieeintrag, gleichzeitig wird die Schichtabsorption reduziert und die Bandkante naehert sich der des Festkoerpers an. Im Vergleich zu konventionell hergestellten Schichten wird die Packungsdichte erhoeht, die Absorption, der Wassergehalt und das Streulicht reduziert. Die Extinktionskoeffizienten bei der Wellenlaenge 532 nm liegen unterhalb von 5.10{sup -5}.Die Ergebnisse der Einzelschichtuntersuchungen werden fuer die Herstellung von Breitbandantireflex-Beschichtungen verwendet. Eine Prozessanpassung fuer die Beschichtung von PMMA kann durch Einsatz von UV-Absorberschichten realisiert werden. Weiterer Schwerpunkt ist die Verguetung von Alkalihalogenidoptiken fuer CO{sub 2}-Hochleistungslaser. Durch die ionengestuetzte Deposition von NaF-Schichten mit extremniedrigen Ionenenergien (E{sub Ion}{approx}5 eV) werden Antireflex-Beschichtungen mit minimalen Absorptionswerten ({alpha}{approx}1.5 cm{sup -1}), hoher Kurzpulszerstoerschwelle (50%-LIDT

    Pulmonary nodules are a frequent finding in computed tomography (CT) investigations. Further diagnostic work-up of detected nodules mainly depends on the so-called pre-test probability, i.e. the probability that the nodule is malignant or benign. The pre-test probability can be calculated by combining all relevant information, such as the age and the sex of the patient, the smoking history, and history of previous malignancies, as well as the size and CT morphology of the nodule. If additional investigations are performed to further investigate the nodules, all results must be interpreted taking into account the pre-test probability and the test performance of the investigation in order to estimate the post-test probability. In cases with a low pre-test probability, a negative result from an exact test can exclude malignancies but a positive test cannot prove malignancy in such a setting. In cases with a high pre-test probability, a positive test result can be considered as proof of malignancy but a negative test result does not exclude malignancy. (orig.)

    The hot gas particulate removal of many advanced coal fired power generation technologies works at temperatures above 800 C. The filter elements for these applications are often based on ceramic materials, e.g. silicon carbide. However, the mostly clay bonded silicon carbide is subject to creep and oxidation due to probable changes of the binder phase. In this work the development of new ceramic filter materials based on silicon carbide and alumina is described. The goal of the development was to increase the potential application temperature. To obtain the goal, the work was performed together with ceramic powder manufacturers, developers of ceramic materials and components as well as with companies who operate test facilities. Different routes were chosen to increase the high temperature resistance in consideration of corrosion resistance, fracture strength and pressure loss of the filter materials. One of these routes was the optimization of the binder phase of the silicon carbide materials. Other routes were concentrated on the base material and the investigation of other possibilities for the silicon carbide bonding, i.e. a recrystallization process of SiC (RSiC) or a self bonding of granulated small grained silicon carbide powder. Additionally filter materials based on alumina were developed. The report covers these material development oriented topics as well as the additional work in materials reliability, coating development and modeling of microstructure. (orig.)

    This study aims at a better understanding of the present-day thermal and hydraulic configuration below the major urban center of Berlin, capital city of Germany. The study area is located in the Northeast German Basin, showing an infill of several kilometers of sediments. Herein, the shallow sedimentary succession is made up of a sequence of alternating aquifers and aquitards, most importantly the local aquitard of the Rupelian clay. This geological unit represents a natural barrier between the deeper saline aquifers and the shallow fresh water aquifers from whom Berlin produces 100% of its drinking water. Additionally, the shallow thermal and hydraulic configuration has been anthropogenically overprinted which may also influence deeper domains to some extent. In this study we make use of 3D thermohydraulic models of the subsurface, focusing on the coupling of surface water bodies to the underground, based on newly available hydraulic data integrated into a 3D hydrogeological model. The results of the study show, that the coupling of surface water bodies and groundwater might lead to significant modifications of predicted subsurface temperatures and fluid flow field. These modifications are most prominent, where differences in hydraulic head between surface water bodies and the adjacent aquifers are highest. Consequently, the predicted surface to groundwater flow field differs most in these areas and it also results in differences in predicted temperatures as a consequence of advective heat transport. Quantitatively, the presence of major lakes may account for temperature differences up to 5°C, while considering rivers only accounts for modifications up to 1°C. Additionally, the models created in this study set up a basis for future thermohaline simulations as saline groundwater may represent a threat to drinking water supply. First results from the models run in this study already indicate, that uprising heated water from deeper domains may rise to shallow

En postulant que ces dispositifs naissent de conflits micro-locaux, nous essaierons d’interroger en quoi ce processus reflète au contraire des enjeux sociaux importants qui se jouent à l’échelle de quartiers. Ce questionnement s’appuiera notamment sur l’hypothèse que l’objet territorial de la participation masque bien souvent des tensions sociales, et donc des conflits d’ordre socio-spatiaux. En analysant deux conflits locaux de gestion urbaine, à Berlin et à Saint-Denis, nous analyserons l’articulation entre ceux-ci et les processus de participation locaux. Les quartiers en marge en constituent un bon cadre d’étude par les processus de ségrégation qui s’y exercent.Die Bürgerbeteiligung wird oft als ein Aktionsfeld ohne politische Wirkunskraft gesehen, in welchem nur lokale Themen behandelt werden; die Bürgerbeteiligung sei nicht fähig die Stadtplanung zu ändern. Das politische Engagement der Bürgerinnen und Bürger erweist sich hingegen als sehr wichtig, wenn man Konflikte der institutionellen Bürgerbeteiligung betrachtet, die sich auf einer mikro-geographischen Ebene abspielen. Die territoriale Verankerung der Bürgerbeteiligung tendiert allerdings dazu, die soziale Komponente der Konflikte zu verdecken.

    Full Text Available We report the sensitivity of the Berlin Climate Middle Atmosphere Model (CMAM to different gravity-wave (GW parameterisations. We perform five perpetual January experiments: 1 Rayleigh friction (RF (control, 2 non-orographic GWs, 3 orographic GWs, 4 orographic and non-orographic GWs with no background stress, and 5 as for 4 but with background stress. We also repeat experiment 4 but for July conditions. Our main aim is to improve the model climatology by introducing orographic and non-orographic parameterisations and to investigate the individual effect of these schemes in the Berlin CMAM. We compare with an RF control to determine the improvement upon a previously-published model version employing RF. Results are broadly similar to previously-published works. The runs having both orographic and non-orographic GWs produce a statistically-significant warming of 4-8K in the wintertime polar lower stratosphere. These runs also feature a cooling of the warm summer pole in the mesosphere by 10-15K, more in line with observations. This is associated with the non-orographic GW scheme. This scheme is also associated with a heating feature in the winter polar upper stratosphere directly below the peak GW-breaking region. The runs with both orographic and non-orographic GWs feature a statistically-significant deceleration in the polar night jet (PNJ of 10-20ms-1 in the lower stratosphere. Both orographic and non-orographic GWs individually produce some latitudinal tilting of the polar jet with height, although the main effect comes from the non-orographic waves. The resulting degree of tilt, although improved, is nevertheless still weaker than that observed.

    Full Text Available We report the sensitivity of the Berlin Climate Middle Atmosphere Model (CMAM to different gravity-wave (GW parameterisations. We perform five perpetual January experiments: 1 Rayleigh friction (RF (control, 2 non-orographic GWs, 3 orographic GWs, 4 orographic and non-orographic GWs with no background stress, and 5 as for 4 but with background stress. We also repeat experiment 4 but for July conditions. Our main aim is to improve the model climatology by introducing orographic and non-orographic parameterisations and to investigate the individual effect of these schemes in the Berlin CMAM. We compare with an RF control to determine the improvement upon a previously-published model version employing RF. Results are broadly similar to previously-published works.

Der erweiterte Ansatz eines Mono-Level-Verfahrens wird fuer zeitinvariante Probleme ausfuehrlich vorgestellt, wobei die Zuverlaessigkeit der Tragwerkselemente im Rahmen der Methode erster Ordnung (FORM) analysiert wird. Fuer eine realitaetsnahe Modellierung vieler praktischer Probleme ist die Verwendung zeitvarianter Zuverlaessigkeitsbetrachtungen notwendig, weshalb verschiedene Verallgemeinerungen der neuen Ansaetze fuer die zeitvariante zuverlaessigkeitsorientierte Strukturoptimierung hergeleitet werden. Einige wichtige Eigenschaften der Optimierungsprobleme werden bewiesen. Ferner werden einige interessante Erweiterungen dieses Mono-Level-Verfahrens, zum Beispiel die Kostenoptimierung von Tragwerkssystemen und die Kostenoptimierung im Rahmen der Zuverlaessigkeitsmethode zweiter Ordnung (SORM), angegeben.

    The project CuRa: (German acronym for Cooperation for Environmentally Friendly Exchange of Resources) aimed to design elements to put into practice the model of sustainable development. The focus was on the participation of industry and business on a regional level and two model regions were chosen for the analysis of case studies. It was intended to give impulses for regional material flow networks between companies, for example by bundling similar material flows to achieve a better profitability and by one-to-one cooperation between companies, one of them using the waste of the partner as raw material. In addition, the potential for reducing material throughput using modern information technology was investigated in a case study. A set of theses derived from institutional theory was verified on the basis of the empirical results. Useful for the development and the stabilization of networks are, among others, expected economic benefits for the partners, common socio-cultural values and traditions, and using existing institutional arrangements as a basis. Different forms of market and policy failures were identified as obstacles, e.g. the established system of waste disposal services, the focus among the responsible actors on compliance with existing rules, and different regulatory obstacles. Nevertheless, in spite of the insufficient number of successful examples and demonstration projects, a shift in orientation from focusing on mere waste disposal towards a closed loop recycling economy and even towards sustainable development was identified within the commercial sector.

    corresponding a low influence of the lateral boundary conditions. Overall, REMO has proved to be a useful tool for a better understanding of the processes in the Arctic and the North Atlantic. Further adjustment of the parameterizations seems to be necessary. Other components of the climate system have to be considered to successfully describe the complex feedbacks and processes of the climate subsystems. (orig.) [German] Die Arktis und der subpolare Nordatlantik bilden mit ihren komplexen Mechanismen und Rueckkopplungen eine wichtige Komponente unseres Klimasystems. Aufgrund der geringen Beobachtungsdichte und der niedrigen Aufloesung globaler Klimamodelle, bietet sich der Einsatz hoeher aufloesender regionaler Klimamodelle an. Das hier verwendete regionale Klimamodell (REMO) basiert auf dem frueheren Wettervorhersagemodell EM des Deutschen Wetterdienstes (DWD) und wurde am Max-Planck-Institut fuer Meteorologie (MPIfM) in Hamburg weiterentwickelt. Fuer die Simulation subskaliger Prozesse stehen zwei Saetze physikalischer Parametrisierungen zur Verfuegung - die urspruenglich verwendete DWD-Physik und die ECHAM4-Physik des MPIfM. Der dynamische Teil ist in beiden Faellen identisch. REMO wird zunaechst an das neue Untersuchungsgebiet angepasst. Die neue Konfiguration beruecksichtigt bei einer horizontalen Aufloesung von 0.5 x 0.5 und 145 x 121 Glitterpunkten die gesamte Arktis und den Nordatlantik bis etwa 40 N. Mit DWD- und ECHAM4-Physik im Vorhersage- und Klima-Mode werden unterschiedliche Zeitraeume simuliert. Als Antriebsdaten werden die NCEP/NCAR-Reanalysen mit einer zeitlichen Aufloesung von 6 Stunden verwendet. Da REMO bisher nur in gemaessigtem Klima eingesetzt wurde, steht der Test des Modells unter den extremen Bedingungen der hohen Breiten im Vordergrund. Beim Vergleich mit Schiffsbeobachtungen aus der Labrador-See liegt REMO deutlich dichter an den Messungen als die Antriebsdaten. Unrealistisch hohe Feuchten in den Reanalysen sind vermutlich die Ursache erhoehter

    Full Text Available A dermal bone from the late Famennian of Ketleri in Latvia, identified as a probable tetrapod postorbital by Oleg Lebedev and stored in the Museum für Naturkunde Berlin, is described in detail. Its tetrapod status is confirmed based on the dermal sculpture consisting of polygonal pits and radially aligned ridges and furrows. The sculpture resembles that of Devonian tetrapods but is nevertheless not as regular as in most post-Devonian forms. The bone can be designated as a postorbital because of its concave anterior margin, the lateral line that shows no bifurcation, and the ossification centre that is located in the dorsal portion of the bone. The lateral line (i.e., the postorbital branch of the infraorbital line forms an open, deep sulcus in the ventral portion of the postorbital but is enclosed within the bone in the dorsal portion and opens through pores to the surface. This morphology of the postorbital branch is unique among basal tetrapods. The bone might belong to the tetrapod Ventastega curonica Ahlberg et al., 1994 that is known from the same strata at Ketleri, however, since the postorbital is unknown in this taxon, this cannot be stated with certainty. doi:10.1002/mmng.201000002

    The internet portal 'herzwegweiser.de' was developed to assist individuals with cardiovascular diseases in the phase III rehabilitation in the region of Berlin-Brandenburg. It provides information on this specific disease as well as on aftercare services, e. g. regional cardiac groups. For the medical and therapeutic colleagues specific information such as treatment guidelines and a cardiac group placement service for trainers and medical doctors were set up. The study was based on a mixed-methods design. Initially, structured interviews were conducted to identify the expectations and needs of the internet portal. After implementation of the portal, a partially standardized written survey was used to evaluate its acceptance and usability. 105 former rehab patients and 42 medical colleagues participated. The evaluation of the questionnaires was carried out with frequency distributions, mean comparisons and Chi-square tests. The site was rated with an overall high approval rating. Over 90% of the former rehab patients rated content, structure, design, and the search function of the portal positive as did more than 85% of the medical colleagues. 97% of the former rehab patients and 95% professionals would recommend 'herzwegweiser.de'. This internet portal can serve as a model for other regions and possibly other diseases. © Georg Thieme Verlag KG Stuttgart · New York.

    Humans spend most of their time in confined spaces and are hence primarily exposed to the direct influence of indoor climate. The Universal Thermal Climate Index (UTCI) was obtained in 31 rooms (eight buildings) in Berlin, Germany, during summer 2013 and 2014. The indoor UTCI was determined from measurements of both air temperature and relative humidity and from data of mean radiant temperature and air velocity, which were either measured or modeled. The associated outdoor UTCI was obtained through facade measurements of air temperature and relative humidity, simulation of mean radiant temperature, and wind data from a central weather station. The results show that all rooms experienced heat stress according to UTCI levels, especially during heat waves. Indoor UTCI varied up to 6.6 K within the city and up to 7 K within building. Heat stress either during day or at night occurred on 35 % of all days. By comparing the day and night thermal loads, we identified maximum values above the 32 °C threshold for strong heat stress during the nighttime. Outd
