    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 ARINC 739 Switch is a computer program that arbitrates control of two multi-function control and display units (MCDUs) between (1) a commercial flight-management computer (FMC) and (2) NASA software used in research on transport aircraft. (MCDUs are the primary interfaces between pilots and FMCs on many commercial aircraft.) This program was recently redesigned into a software library that can be embedded in research application programs. As part of the redesign, this software was combined with software for creating custom pages of information to be displayed on a CDU. This software commands independent switching of the left (pilot s) and right (copilot s) MCDUs. For example, a custom CDU page can control the left CDU while the FMC controls the right CDU. The software uses menu keys to switch control of the CDU between the FMC or a custom CDU page. The software provides an interface that enables custom CDU pages to insert keystrokes into the FMC s CDU input interface. This feature allows the custom CDU pages to manipulate the FMC as if it were a pilot.

    Full Text Available High-fidelity color image reproduction is one of the key issues invisual telecommunication systems, for electronic commerce,telemedicine, digital museum and so on. All colorimetric standards ofdisplay systems are up to the present day trichromatic. But, from theshape of a horseshoe-area of all existing colors in the CIE xychromaticity diagram it follows that with three real reproductivelights, the stated area in the CIE xy chromaticity diagram cannot beoverlaid. The expansion of the color gamut of a display device ispossible in a few ways. In this paper, the way of increasing the numberof primaries is studied. The fourth cyan primary is added to threeconventional ones to enlarge the color gamut of reproduction towardscyans and yellow-oranges. The original method of color management forthis new display unit is introduced. In addition, the color gamut ofthe designed additive-based display is successfully compared with thecolor gamut of a modern subtractive-based system. A display with morethan three primary colors is called a multiprimary color display. Thevery advantageous property of such display is the possibility todisplay metameric colors.

    2015-05-01

    Project Manager (PM) Apache Block III contacted the U.S. Army Aeromedical Research Laboratory (USAARL), Fort Rucker, Alabama, requesting assistance to evaluate and find solutions to a government-developed Helmet Display Unit (HDU) device called the Mock HDU for helmet alignment of the Apache Advanced Integrated Helmet (AAIH). The AAIH is a modified Head Gear Unit No. 56 for Personnel (HGU-56/P) to replace the current Integrated Helmet and Sighting System (IHADSS). The current flashlight-based HDU simulator for helmet/HDU alignment was no longer in production or available. Proper helmet/HDU alignment is critical to position the right eye in the small HDU eye box to obtain image alignment and full field of view (FOV). The initial approach of the PM to developing a helmet/HDU fitting device (Mock HDU) was to duplicate the optical characteristics of the current tactical HDU using less complex optics. However, the results produced questionable alignment, FOV, and distortion issues, with cost and development time overruns. After evaluating the Mock HDU, USAARL proposed a cost effective, less complex optical design called the Helmet/HDU Alignment Tool (HAT). This paper will show the development, components, and evaluations of the HAT compared to the current flashlight HDU simulator device. The laboratory evaluations included FOV measurements and alignment accuracies compared to tactical HDUs. The Apache helmet fitter technicians and Apache pilots compared the HAT to the current flashlight based HDU and ranked the HAT superior.

    1988-01-01

    The introduction and acceptance of video display units at work have led to a huge flood of information, rumours, and half-truths about those units. As the population became increasingly sensitized to 'radioactive radiation', there was, and in part still is, a tendency to consider particularly effects of unclear origin, first of all ionizing radiation and later on also non-ionizing radiation, as the main threat from video display units at work. Such important issuses as ergonomics, stress load, visual stress load, and social hygiene are often effaced by the question for 'the radiation load from visual display units'. The paper is an attempt to deal with aspects of radiation effects of visual display units at work. The discussion also extends to hazards, respectively the 'radiation environment', at the site of the visual display unit. (orig./DG) [de

  11. A low-cost general purpose spectral display unit using an IBM PC

    Robinson, S.L.

    1986-01-01

    Many physics experiments require acquisition and analysis of spectral data. Commercial minicomputer-based multichannel analyzers collect detected counts at various energies, create a histogram of the counts in memory, and display the resultant spectra. They acquire data and provide the user-to-display interface. The system discussed separates functions into the three modular components of data acquisition, storage, and display. This decoupling of functions allows the experimenter to use any number of detectors for data collection before forwarding up to 64 spectra to the display unit, thereby increasing data throughput over that available with commercial systems. An IBM PC was chosen for the low-cost, general purpose display unit. Up to four spectra may be displayed simultaneously in different colors. The histogram saves 1024 channels per detector, 640 of which may be distinctly displayed per spectra. The IEEE-488 standard provides the data path between the IBM PC and the data collection unit. Data is sent to the PC under interrupt control, using direct memory access. Display manipulations available via keyboard are also discussed

    This study was carried out to ensure the adequacy and accuracy of the Dynalyser Digital Display unit for measuring the true kVp from the invasive kVp meter unit during calibration of non-invasive kVp meters. An invasive high voltage divider (dynalyser) coupled to the x-ray system measures the true kilo voltage supplied to the x-ray tube. The kVp output measured was displayed via its digital display unit while its waveform was acquired using a calibrated oscilloscope. The waveform was used to calculate the Practical Peak Voltage (PPV) using the International Standard method adapted from IEC 61676 and treated as the true kVp value. The kVp output was measured at 9 points ranging between 40 kV-120 kV with interval steps of 10 kV and monitored every day. The test result was evaluated for variation of output, intrinsic error and limit of variation in compliance with the IEC standard. Results showed that kVp output measured by the display unit everyday is consistent with variations of not more than ±0.45 kV, intrinsic error of not more than ±0.009 kV and limits of variation of less than 1% which comply with the IEC standard requirement. The kVp output via digital display unit has a total uncertainty of not more than 2.8 kV (k=2) while the PPV output via oscilloscope has total uncertainty of not more than 0.75 kV (k=2). As a conclusion, the dynalyser digital display unit complies with standard requirement and can be used to measure the true kVp output during the calibration of non-invasive kVp meters. (author)

    1990-01-01

    This task concerns the design, development, testing, and evaluation of a new proximity operations planning and flight guidance display and control system for manned space operations. A forecast, derivative manned maneuvering unit (MMU) was identified as a candidate for the application of a color, highway-in-the-sky display format for the presentation of flight guidance information. A silicon graphics 4D/20-based simulation is being developed to design and test display formats and operations concepts. The simulation includes the following: (1) real-time color graphics generation to provide realistic, dynamic flight guidance displays and control characteristics; (2) real-time graphics generation of spacecraft trajectories; (3) MMU flight dynamics and control characteristics; (4) control algorithms for rotational and translational hand controllers; (5) orbital mechanics effects for rendezvous and chase spacecraft; (6) inclusion of appropriate navigation aids; and (7) measurement of subject performance. The flight planning system under development provides for: (1) selection of appropriate operational modes, including minimum cost, optimum cost, minimum time, and specified ETA; (2) automatic calculation of rendezvous trajectories, en route times, and fuel requirements; (3) and provisions for manual override. Man/machine function allocations in planning and en route flight segments are being evaluated. Planning and en route data are presented on one screen composed of two windows: (1) a map display presenting a view perpendicular to the orbital plane, depicting flight planning trajectory and time data attitude display presenting attitude and course data for use en route; and (2) an attitude display presenting local vertical-local horizontal attitude data superimposed on a highway-in-the-sky or flight channel representation of the flight planned course. Both display formats are presented while the MMU is en route. In addition to these displays, several original display

  16. 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 United States Air Force has conducted an extensive research effort to determine the most effective way to present aircraft control, performance, and navigation information on the head-up display (HUD). The primary objective of the research was to develop a standard HUD symbology set to be used as a primary flight reference for fighter-type aircraft during instrument meteorological conditions. This paper summarizes the research conducted by scientists in the Visual Orientation Laboratory at the Flight Motion Effects Branch of the Human Systems Center's Armstrong Laboratory. Five experiments that examined various control and performance symbology elements are reviewed. Suggested standardization guidelines based on experimental findings are discussed, including the following: the use of counter-pointers for airspeed and altitude indicators, vertical and horizontal asymmetry for climb/dive ladder configurations, a ghost horizon, analog vertical-velocity information, energy management symbology, and quickening for climb/dive markers.

  2. A Comparison of Two Control Display Unit Concepts on Flight Management System Training

    Abbott, Terence S.

    1997-01-01

    One of the biggest challenges for a pilot in the transition to a 'glass' cockpit is understanding the flight management system (FMS). Because of both the complex nature of the FMS and the pilot-FMS interface, a large portion of transition training is devoted to the FMS. The current study examined the impact of the primary pilot-FMS interface, the control display unit (CDU), on FMS training. Based on the hypothesis that the interface design could have a significant impact on training, an FMS simulation with two separate interfaces was developed. One interface was similar to a current-generation design, and the other was a multiwindows CDU based on graphical user interface techniques. For both application and evaluation reasons, constraints were applied to the graphical CDU design to maintain as much similarity as possible with the conventional CDU. This preliminary experiment was conducted to evaluate the interface effects on training. Sixteen pilots with no FMS experience were used in a between-subjects test. A time-compressed, airline-type FMS training environment was simulated. The subjects were trained to a fixed-time criterion, and performance was measured in a final, full-mission simulation context. This paper describes the technical approach, simulation implementation, and experimental results of this effort.

  3. Cross-Modal Brain Plasticity in Congenital Blindness: Lessons from the Tongue Display Unit

    Directory of Open Access Journals (Sweden)

    Ron Kupers

    2011-10-01

    Full Text Available The tongue display unit (TDU is a sensory substitution device that translates visual information into electrotactile stimulation that is applied to the tongue. Blind subjects can learn to use the TDU in various visual tasks, including orientation, motion and shape identification, and spatial navigation. We used the TDU in conjunction with brain imaging techniques in order to study the cerebral correlates of cross-modal brain plasticity. The results show that when blind subjects use the TDU to perform visual tasks that are known to activate the dorsal and ventral visual streams in the sighted, they activate the same brain areas. This suggests that motion and shape processing are organized in a supramodal manner in the human brain and that vision is not necessary for the development of the functional architecture in motion and shape processing areas. We also used the TDU in spatial navigation tasks. The results showed that blind but not blindfolded sighted subjects activated their visual cortex and right parahippocampus during navigation, suggesting that in the absence of vision, cross-modal plasticity permits the recruitment of the same cortical network used for spatial navigation tasks in sighted subjects.

    Full Text Available Background: Epidemiological studies have shown that employees working with visual display units (VDU are more likely to complain about musculoskeletal disorders (MSDs. The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. Material and Methods: A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity and work-related factors (i.e., predominant job tasks performed, work posture. Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs and workstations. Adjusted odds ratios (ORa were calculated by means of the logistic regression model. Results: Prevalence of MSDs was relatively high (53%. In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI: 2.178–3.683, age ≥ 50 years old (OR = 2.231, 95% CI: 1.236–4.026, longer exposure to VDU, both as working history (10–14 years: OR = 1.934, 95% CI: 1.301–2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510–3.271 and working time (30–39 h/week: OR = 1.537, 95% CI: 1.087–2.273. Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124–5.018. Conclusions: Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6:707–719

Signs and symptoms were collected during compulsory occupational medical surveillance. The binary logistic regression was used to estimate adjusted odds ratios for the factors of interest. Results: Diagnosis of CTS was reported in 48 cases (7.6%, 11 of them or 1.7% after a surgical correction for the incidence of 5.94/1000 person-years. In general, signs and symptoms of CTS were associated with the following demographic factors: previous trauma of upper limb (adjusted odds ratio (ORa = 8.093, 95% confidence interval (CI: 2.347–27.904, history (> 5 years of oral contraceptives therapy/hormone replacement therapy (ORa = 3.77, 95% CI: 1.701–8.354 and cervical spine signs/symptoms (ORa = 4.565, 95% CI: 2.281–9.136. Conclusions: The prevalence of CTS was similar to the estimates for the general population of Italy. Among personal risk factors, hormone therapy, previous trauma of the upper limb and signs/symptoms of the cervical spine appeared to be associated with a higher risk of CTS syndrome. Eventually, the results reinforce interpretation of CTS in VDU workers as a work-related musculoskeletal disorder rather than a classical occupational disease.

    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.

    Full Text Available The expectation that Berlin, at the cusp of the twenty-first century, should produce "big-city" novels that, like Döblin's Berlin Alexanderplatz in its own time, would catch the encounters, juxtapositions, and historical layerings of the newly reunified capital is perhaps unfair, and certainly a high bar, but it reflects widespread interest in literary representations of this brazenly, even insolently transformed city...

    Near Berlin, Germany, several juvenile red squirrels (Sciurus vulgaris) were found with moist, crusty skin lesions. Histology, electron microscopy, and cell culture isolation revealed an orthopoxvirus-like infection. Subsequent PCR and genome analysis identified a new poxvirus (Berlin squirrelpox virus) that could not be assigned to any known poxvirus genera.

    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.

    Current digital instrumentation and control and main control room (MCR) technology has extended the capability of integrating information from numerous plant systems and transmitting needed information to operations personnel in a timely manner that could not be envisioned when previous generation plants were designed and built. A MCR operator can complete all necessary operating actions on the video display unit (VDU). It is extremely flexible and convenient for operators to select and to control the system display on the screen. However, a high degree of digitalization has some risks. For example, in nuclear power plants, failures in the instrumentation and control devices could stop the operation of the plant. Human factors engineering (HFE) approaches would be a manner to solve this problem. Under HFE considerations, there exists 'population stereotype' for operation. That is, the operator is used to operating a specific display on the specific VDU for operation. Under emergency conditions, there is possibility that the operator will response with this habit population stereotype, and not be aware that the current situation has already changed. Accordingly, the advanced nuclear power plant should establish the MCR VDU configuration plan to meet the consistent teamwork goal under normal operation, transient and accident conditions. On the other hand, the advanced nuclear power plant should establish the human factors verification and validation plan of the MCR VDU configuration to verify and validate the configuration of the MCR VDUs, and to ensure that the MCR VDU configuration allows the operator shift to meet the HFE consideration and the consistent teamwork goal under normal operation, transient and accident conditions. This paper is one of the HF V V plans of the MCR VDU configuration of the advanced nuclear power plant.

  20. Collapsing (New Buildings: Town Planning, History and Music in Hubertus Siegert's Berlin Babylon (2001

    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.

    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.

    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.

  10. 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.

  11. Branding Asklepios and the Traditional and Variant Serpent Symbol Display Among Health Professional Schools in the United States, Puerto Rico, and Canada: A Cross-Sectional Survey.

    History supports the staff and single serpent, the asklepian, as the symbol of healing and medicine, yet its confusion with the caduceus (a winged staff with two snakes wrapped around it) persists. No population-based information on serpent symbol use exists. To determine the prevalence of asklepian and caduceus display among Internet images of medical and health professional schools' emblems, and to compare asklepian and caduceus display between medical and health professional schools, examining the effects of school longevity and geographic location on symbol display. This cross-sectional survey examined Internet websites and Google Images associated with medical and other health professional schools in the United States, Puerto Rico, and Canada from 2013 to 2015. The primary outcome was display of a traditional or variant asklepian or caduceus among current and past emblems in Google Images. Odds ratios (ORs) and 95% confidence intervals for the comparison of medical versus other health professional schools were calculated by logistic regression. Differences among schools' longevity were assessed with Student's t-tests and linear regression. Among images of current and past emblems of 482 schools-159 medical schools and 323 health professional schools-107 (22.2%) emblems displayed only the traditional, and 205 (42.5%) any, asklepian. Adjusting for geographic region and longevity, medical schools were 59% less likely than health professional schools to display the traditional asklepian (OR 0.41, 95% CI 0.24-0.71, P=.001), and were 7.7 times more likely than health professional schools to display the traditional caduceus. Medical schools were 8% less likely than health professional schools to display any asklepian (OR 0.92, 95% CI 0.62-1.38, P=.70), and were 3.3 times more likely than health professional schools to display any caduceus. Schools' preference of the asklepian over the caduceus confirmed historical origins. Less asklepian and more caduceus display by

    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.

    1993-01-01

    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

    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.

    2010-01-01

    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.

    2017-12-01

    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.

  19. 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.

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

    Science.gov (United States)

    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.

    S1 satellite DNA from Palearctic brown frogs has a species-specific structure in all European species. We characterized S1 satellite DNA from the Anatolian brown frogs Rana macrocnemis, R. camerani, and R. holtzi in order to define their taxonomic rank and the structure of this satellite in this frog lineage. Southern blots of genomic DNA digested with KpnI, EcoRV, NdeI, NheI, or StuI produced the same pattern of satellite DNA bands. Moreover, quantitative dot blots showed that this satellite DNA accounts for 0.1 % of the genome in all taxa. Analysis of the overall genomic variability of the S1a repeat sequence in specimens from various populations demonstrated that this repetitive unit also has the same size (476 bp), the same most common sequence (MCS) and the same overall variability in all three taxa, and also in R. macrocnemis tavasensis. The S1a repetitive unit presents three deletions of 9, 8 and 1 bp compared to the 494-bp S1a repeat from European frogs. The S1a MCS has three variable positions (sequence WWTK in positions 183-186), due to the presence of two repeat subpopulations with motifs AATG and WWTT in all taxa. Unlike previously analyzed mitochondrial and nuclear sequences that show considerable variations among these taxa, no difference could be detected in the structure and variability of the S1 satellite repetitive units. This suggests that these taxa should belong to a single species. Our results indicate that this satellite DNA variety probably formed when the Anatolian lineage radiated from common ancestor about 4 mya, and since then has maintained its structure in all four taxa examined.

  3. 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

    Projection display in today's market is dominated by cathode ray tubes (CRTs). Further progress in this mature CRT projector technology will be slow and evolutionary. Liquid crystal based projection displays have gained rapid acceptance in the business market. New technologies are being developed on several fronts: (1) active matrix built from polysilicon or single crystal silicon; (2) electro- optic materials using ferroelectric liquid crystal, polymer dispersed liquid crystals or other liquid crystal modes, (3) micromechanical-based transducers such as digital micromirror devices, and grating light valves, (4) high resolution displays to SXGA and beyond, and (5) high brightness. This article reviews the projection displays from a transducer technology perspective along with a discussion of markets and trends.

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

    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.

  8. Berlin in Television Drama Series: A Mediated Space

    Directory of Open Access Journals (Sweden)

    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.

    2002-05-01

    A 3D head mounted display (HMD) system is useful for constructing a virtual space. The authors have researched the virtual-reality systems connected with computer networks for real-time remote control and developed a low-priced real-time 3D display for building these systems. We developed a 3D HMD system using monocular multi-view displays. The 3D displaying technique of this monocular multi-view display is based on the concept of the super multi-view proposed by Kajiki at TAO (Telecommunications Advancement Organization of Japan) in 1996. Our 3D HMD has two monocular multi-view displays (used as a visual display unit) in order to display a picture to the left eye and the right eye. The left and right images are a pair of stereoscopic images for the left and right eyes, then stereoscopic 3D images are observed.

    "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.

  19. Reconstruction of Berlin, in search of a new identity

    2008-12-01

    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.

    Directory of Open Access Journals (Sweden)

    Alison Lewis

    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.

    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.

  19. The Berlin tradition in Chicago: Franz Alexander and the Chicago Institute for Psychoanalysis.

    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.

    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.

    2014-01-01

    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.

    We present the image processing upgrades implemented on a Graphics Processing Unit (GPU) in the Control, Acquisition, Processing, and Image Display System (CAPIDS) for the custom Micro-Angiographic Fluoroscope (MAF) detector. Most of the image processing currently implemented in the CAPIDS system is pixel independent; that is, the operation on each pixel is the same and the operation on one does not depend upon the result from the operation on the other, allowing the entire image to be processed in parallel. GPU hardware was developed for this kind of massive parallel processing implementation. Thus for an algorithm which has a high amount of parallelism, a GPU implementation is much faster than a CPU implementation. The image processing algorithm upgrades implemented on the CAPIDS system include flat field correction, temporal filtering, image subtraction, roadmap mask generation and display window and leveling. A comparison between the previous and the upgraded version of CAPIDS has been presented, to demonstrate how the improvement is achieved. By performing the image processing on a GPU, significant improvements (with respect to timing or frame rate) have been achieved, including stable operation of the system at 30 fps during a fluoroscopy run, a DSA run, a roadmap procedure and automatic image windowing and leveling during each frame.

    Displays have several functions: to transmit images, to permit interaction, to quantitate features and to provide records. The main characteristics of displays used for image transmission are their resolution, dynamic range, signal-to-noise ratio and uniformity. Considerations of visual acuity suggest that the display element size should be much less than the data element size, and in current practice at least 256X256 for a gamma camera image. The dynamic range for image transmission should be such that at least 64 levels of grey (or equivalent) are displayed. Scanner displays are also considered, and in particular, the requirements of a whole-body camera are examined. A number of display systems and devices are presented including a 'new' heated object colour display system. Interaction with displays is considered, including background subtraction, contrast enhancement, position indication and region-of-interest generation. Such systems lead to methods of quantitation, which imply knowledge of the expected distributions. Methods for intercomparing displays are considered. Polaroid displays, which have for so long dominated the field, are in the process of being replaced by stored image displays, now that large cheap memories exist which give an equivalent image quality. The impact of this in nuclear medicine is yet to be seen, but a major effect will be to enable true quantitation. (author)

    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.

    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.

    The Polyplanar Optical Display (POD) is a unique display screen which can be used with any projection source. This display screen is 2 inches thick and has a matte black face which allows for high contrast images. The prototype being developed is a form, fit and functional replacement display for the B-52 aircraft which uses a monochrome ten-inch display. The new display uses a 100 milliwatt green solid state laser (532 nm) as its optical source. In order to produce real-time video, the laser light is being modulated by a Digital Light Processing (DLP{trademark}) chip manufactured by Texas Instruments, Inc. A variable astigmatic focusing system is used to produce a stigmatic image on the viewing face of the POD. In addition to the optical design, the authors discuss the electronic interfacing to the DLP{trademark} chip, the opto-mechanical design and viewing angle characteristics.

  14. 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.

    This toolkit provides a common interface for displaying graphical user interface (GUI) components in stereo using either specialized stereo display hardware (e.g., liquid crystal shutter or polarized glasses) or anaglyph display (red/blue glasses) on standard workstation displays. An application using this toolkit will work without modification in either environment, allowing stereo software to reach a wider audience without sacrificing high-quality display on dedicated hardware. The toolkit is written in Java for use with the Swing GUI Toolkit and has cross-platform compatibility. It hooks into the graphics system, allowing any standard Swing component to be displayed in stereo. It uses the OpenGL graphics library to control the stereo hardware and to perform the rendering. It also supports anaglyph and special stereo hardware using the same API (application-program interface), and has the ability to simulate color stereo in anaglyph mode by combining the red band of the left image with the green/blue bands of the right image. This is a low-level toolkit that accomplishes simply the display of components (including the JadeDisplay image display component). It does not include higher-level functions such as disparity adjustment, 3D cursor, or overlays all of which can be built using this toolkit.

In order to use the solid-state laser as the light source and also fit within the constraints of the B-52 display, the digital micromirror device (DMD) circuit board is removed from the Texas Instruments DLP light engine assembly. Due to the compact architecture of the projection system within the display chassis, the DMD chip is operated remotely from the Texas Instruments circuit board. We discuss the operation of the DMD divorced from the light engine and the interfacing of the DMD board with various video formats including the format specific to the B-52 aircraft. A brief discussion of the electronics required to drive the laser is also presented.

This article wants to reveal the tools that are essential in creating a fabulous window display. Being a window designer is not an easy job, you have to always think ahead trends, to have a sense of colour, to know how to use light to attract customers in the store after only one glance at the window. The big store window displays are theatre scenes: with expensive backgrounds, special effects and high fashion mannequins. The final role of the displays is to convince customers to enter the store and trigger the purchasing act which is the final goal of the retail activity.

    1997-07-01

    Laser Power Corporation has developed a new type of projection display, based upon microlaser technology and a novel scan architecture, which provides the foundation for bright, extremely high resolution images. A review of projection technologies is presented along with the limitations of each and the difficulties they experience in trying to generate high resolution imagery. The design of the microlaser based projector is discussed along with the advantage of this technology. High power red, green, and blue microlasers have been designed and developed specifically for use in projection displays. These sources, in combination with high resolution, high contrast modulator, produce a 24 bit color gamut, capable of supporting the full range of real world colors. The new scan architecture, which reduces the modulation rate and scan speeds required, is described. This scan architecture, along with the inherent brightness of the laser provides the fundamentals necessary to produce a 5120 by 4096 resolution display. The brightness and color uniformity of the display is excellent, allowing for tiling of the displays with far fewer artifacts than those in a traditionally tiled display. Applications for the display include simulators, command and control centers, and electronic cinema.

    2012-01-01

    This essay considers the rhetoric of space in a rapidly transforming culture. Using Michel Foucault's concept of "heterotopias" to understand the rhetorical power of a building's disposition, it is argued that the Jewish Museum Berlin contains two heterotopias, one within the other. The first is Daniel Libeskind's original building…

  10. Vier Jahre „Berliner Aktionsprogramm gegen Ambrosia“: Erfolge und Grenzen

    Directory of Open Access Journals (Sweden)

    Kannabel, Sandra

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

  17. 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.

    2018-02-01

    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.

  2. Information rich display design

    International Nuclear Information System (INIS)

    Welch, Robin; Braseth, Alf Ove; Veland, Oeystein

    2004-01-01

    This paper presents the concept Information Rich Displays. The purpose of Information Rich Displays (IRDs) is to condensate prevailing information in process displays in such a way that each display format (picture) contains more relevant information for the user. Compared to traditional process control displays, this new concept allows the operator to attain key information at a glance and at the same time allows for improved monitoring of larger portions of the process. This again allows for reduced navigation between both process and trend displays and ease the cognitive demand on the operator. This concept has been created while working on designing display prototypes for the offshore petroleum production facilities of tomorrow. Offshore installations basically consist of wells, separation trains (where oil, gas and water are separated from each other), an oil tax measurement system (where oil quality is measured and the pressure increased to allow for export), gas compression (compression of gas for export) and utility systems (water treatment, chemical systems etc.). This means that an offshore control room operator has to deal with a complex process that comprises several functionally different systems. The need for a new approach to offshore display format design is in particular based on shortcomings in today's designs related to the keyhole effect, where the display format only reveals a fraction of the whole process. Furthermore, the upcoming introduction of larger off- and on-shore operation centres will increase the size and complexity of the operators' work domain. In the light of the increased demands on the operator, the proposed IRDs aim to counter the negative effects this may have on the workload. In this work we have attempted to classify the wide range of different roles an operator can have in different situations. The information content and amount being presented to the operator in a display should be viewed in context of the roles the

    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''.

  6. Stereo Painting Display Devices

    1982-06-01

    The Spanish Surrealist artist Salvador Dali has recently perfected the art of producing two paintings which are stereo pairs. Each painting is separately quite remarkable, presenting a subject with the vivid realism and clarity for which Dali is famous. Due to the surrealistic themes of Dali's art, however, the subjects preser.ted with such naturalism only exist in his imagination. Despite this considerable obstacle to producing stereo art, Dali has managed to paint stereo pairs that display subtle differences of coloring and lighting, in addition to the essential perspective differences. These stereo paintings require a display method that will allow the viewer to experience stereo fusion, but which will not degrade the high quality of the art work. This paper gives a review of several display methods that seem promising in terms of economy, size, adjustability, and image quality.

    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.)

    1997-01-01

    Carjackings are only one of a growing class of law enforcement problems associated with increasingly violent crimes and accidents involving automobiles plays weapons, drugs and alcohol. Police traffic stops have become increasingly dangerous, with an officer having no information about a vehicle's potentially armed driver until approaching him. There are 15 million alcoholics in the US and 90 percent of them have drivers licenses. Many of them continue driving even after their licenses have ben revoked or suspended. There are thousands of unlicensed truck drivers in the country, and also thousands who routinely exceed safe operating periods without rest; often using drugs in an attempt to stay alert. MIKOS has developed the Drivers License Display Systems to reduce these and other related risks. Although every state requires the continuous display of vehicle registration information on every vehicle using public roads, no state yet requires the display of driver license information. The technology exists to provide that feature as an add-on to current vehicles for nominal cost. An initial voluntary market is expected to include: municipal, rental, and high value vehicles which are most likely to be mis-appropriated. It is anticipated that state regulations will eventually require such systems in the future, beginning with commercial vehicles, and then extending to high risk drivers and eventually all vehicles. The MIKOS system offers a dual-display approach which can be deployed now, and which will utilize all existing state licenses without requiring standardization.

    Lee, Cheok Peng; Asundi, A.; Yu, Yang; Xiao, Zhen Zhong

    This paper describes the extension work from the last Digital Holography Projector System. From the developed works shows that, some unforeseen factors have created the difficulties for the system alignment. Such factors are the DMD frame rate, light source and diffractive zero order. It is really the challenging development works to achieve the virtual 3D model display on the high speed rotation screen. The three most key factors are emphasizing: 1) The display device's frame rate; 2) The light source orientation angle; and 3) The zero order filtering optic. 1) This device's is the digital micro mirror, in short is DMD. It is the high speed switching device has developed by the most recent technology. The switching frame rate can go up as high as 291fps. At first, the 8 bits depth file must be digitalized and stored for DMD onboard Ram. The digitalized data are transmitting from the PC USB to DMD onboard Ram. Instead of the data are downloading directly from the PC to DVI or VGA during display, this downloading method cause slower down the display speed, which is the common frame rate of 30 Hz. Next, the onboard Ram data then transfer to the DMD mirror's for display, at the 8 bits 291 fps speed. At this frame rate, the display 2D image can almost cover for 10 of out of the 360 0 in 1 revolution. 2) This laser light source must be installed such that free for orientated in any arbitrary angle from 220 to 450. Which is normalized to the DMD mirrors and the brief sketch show on figure (a). The purpose of orientated the light source is ensure that multi diffractive order would be reflected straight from the mirrors. (This multi diffractive order is the phenomenon of the digital micro mirror's characteristic). This mean, the reconstruct images would be followed the DMD normalized direction reflected up to fibre conduit. Moreover, this orientated method install of the laser light source is making space for other optical lenses or device driver/controller. Because, all

    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.

    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.

    Full Text Available Since the late 1950's, a steadily increasing immigrant population in Germany is resulting in a subpopulation of aging immigrants. The German health care system needs to adjust its services-linguistically, culturally, and medically-for this subpopulation of patients. Immigrants make up over 20% of the population in Germany, yet the majority receive inadequate medical care. As many of the labor immigrants of the 1960s and 1970s are in need of hospice and palliative care (HPC, little is known about this specialized care for immigrants. This epidemiological study presents utilization of HPC facilities in Berlin with a focus on different immigrant groups.A validated questionnaire was used to collect data from patients at 34 HPC institutions in Berlin over 20 months. All newly admitted patients were recruited. Anonymized data were coded and analyzed by using SPSS and compared with the population statistics of Berlin.4118 questionnaires were completed and included in the analysis. At 11.4% the proportion of immigrants accessing HPC was significantly (p<0,001 below their proportion in the general Berlin population. This difference was especially seen in the age groups of 51-60 (21.46% immigrants in Berlin population, 17.7% immigrants in HPC population and 61-70 years (16,9% vs. 13,1%.

    Since the late 1950's, a steadily increasing immigrant population in Germany is resulting in a subpopulation of aging immigrants. The German health care system needs to adjust its services-linguistically, culturally, and medically-for this subpopulation of patients. Immigrants make up over 20% of the population in Germany, yet the majority receive inadequate medical care. As many of the labor immigrants of the 1960s and 1970s are in need of hospice and palliative care (HPC), little is known about this specialized care for immigrants. This epidemiological study presents utilization of HPC facilities in Berlin with a focus on different immigrant groups. A validated questionnaire was used to collect data from patients at 34 HPC institutions in Berlin over 20 months. All newly admitted patients were recruited. Anonymized data were coded and analyzed by using SPSS and compared with the population statistics of Berlin. 4118 questionnaires were completed and included in the analysis. At 11.4% the proportion of immigrants accessing HPC was significantly (p<0,001) below their proportion in the general Berlin population. This difference was especially seen in the age groups of 51-60 (21.46% immigrants in Berlin population, 17.7% immigrants in HPC population) and 61-70 years (16,9% vs. 13,1%). The largest ethnic groups are Turks, Russians, and Poles, with a different weighting than in the general population: Turkish immigrants were 24% of all Berlin immigrants, but only 13.6% of the study immigrant population (OR: 0.23, 95%CI: 0.18-0.29, p<0.001). Russian and Polish immigrants account for 5.6% and 9.2% in the population, but 11.5% and 24.8% in the study population respectively (Russian: OR 0.88, 95%CI: 0.66-1.16; Polish: OR 1.17, 95%CI: 0.97-1.42). Palliative care wards (PC) were used most often (16.7% immigrants of all PC patients); outpatient hospice services were used least often by immigrants (11.4%).

    This article highlights the life and work of Bernhard Pollack (1865-1928), a pioneer neurohistologist, ophthalmologist, and world-class pianist. In 1897, Pollack published the first standard manual on staining methods for the nervous system. Born into a Prussian-Jewish family, he received his piano education from the composer Moritz Moszkowski and his pathology education from Carl Weigert. Pollack worked in the Institutes of Wilhelm Waldeyer (anatomy), Emanuel Mendel (neuropsychiatry), the later Nobel laureate Robert Koch (infectious diseases), and the Eye Policlinic of Paul Silex (ophthalmology), becoming a Professor of Ophthalmology at Berlin's Friedrich-Wilhelms-Universität in 1919. The study also chronicles the founding by Pollack of the Berlin Doctors' Orchestra in 1911. Copyright © 2012 S. Karger AG, Basel.

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

    Full Text Available This paper concentrates on the strategies of reconstructing the past as  inscribed into the urban space of Berlin and discussed within the literary field. 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.

    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.

    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.

    Full Text Available After the fall of the Berlin Wall and the breakdown of the East German Socialistgovernment, thousands of former contract workers from Vietnam stayedin the then reunified Germany. 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.

    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

  11. Attention-Seeking Displays.

    Directory of Open Access Journals (Sweden)

    Szabolcs Számadó

    Full Text Available Animal communication abounds with extravagant displays. These signals are usually interpreted as costly signals of quality. However, there is another important function for these signals: to call the attention of the receiver to the signaller. While there is abundant empirical evidence to show the importance of this stage, it is not yet incorporated into standard signalling theory. Here I investigate a general model of signalling - based on a basic action-response game - that incorporates this searching stage. I show that giving attention-seeking displays and searching for them can be an ESS. This is a very general result and holds regardless whether only the high quality signallers or both high and low types give them. These signals need not be costly at the equilibrium and they need not be honest signals of any quality, as their function is not to signal quality but simply to call the attention of the potential receivers. These kind of displays are probably more common than their current weight in the literature would suggest.

    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

    Panoramic images with a wide field of view intend to provide a better understanding of an environment by placing objects of the environment on one seamless image. However, understanding the sizes and relative positions of the objects in a panorama is not intuitive and prone to errors because the field of view is unnatural to human perception. Scientists are often faced with the difficult task of interpreting the sizes and relative positions of objects in an environment when viewing an image of the environment on computer monitors or prints. A panorama can display an object that appears to be to the right of the viewer when it is, in fact, behind the viewer. This misinterpretation can be very costly, especially when the environment is remote and/or only accessible by unmanned vehicles. A 270 cylindrical display has been developed that surrounds the viewer with carefully calibrated panoramic imagery that correctly engages their natural kinesthetic senses and provides a more accurate awareness of the environment. The cylindrical immersive display offers a more natural window to the environment than a standard cubic CAVE (Cave Automatic Virtual Environment), and the geometry allows multiple collocated users to simultaneously view data and share important decision-making tasks. A CAVE is an immersive virtual reality environment that allows one or more users to absorb themselves in a virtual environment. A common CAVE setup is a room-sized cube where the cube sides act as projection planes. By nature, all cubic CAVEs face a problem with edge matching at edges and corners of the display. Modern immersive displays have found ways to minimize seams by creating very tight edges, and rely on the user to ignore the seam. One significant deficiency of flat-walled CAVEs is that the sense of orientation and perspective within the scene is broken across adjacent walls. On any single wall, parallel lines properly converge at their vanishing point as they should, and the sense of

    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 Paintings in museums might occasionally be replaced by a photoprint mimicking the original. This article is an investigation of what constitutes a good reproduction of an artwork (oil painting that is meant to be displayed. The article discusses what the usefulness of reproductions depends on, applying the Valuation Studies approach, which means the primary concern is with the practice of valuing itself. In other words, the study focuses on how museum experts evaluate reproduc-tions of oil paintings. The article analyses three cases of displaying digitally prin-ted copies of Edvard Munch's oil paintings between 2013 and 2015 in the Munch Museum and in the National Gallery in Oslo. The study is based on a series of semi-structured interviews with the experts, working at and for the museums, that were involved in producing and exhibiting of the photoprints: curators, con-servators, museum educators, and external manufacturers. The interviews were grouped into five clusters, which I have chosen to call registers of valuing following Frank Heuts and Annemarie Mol (2013. The described valuation practices have to do with delivering experiences to the public, obtaining mimetic resemblance, solving ethical aspects, exhibitions' budget, and last but not least, with the time perspective.

    2012-08-01

    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.

    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

    The safety display of nuclear system has been classified as important to safety (SIL:Safety Integrity Level 3). These days the regulatory agencies are imposing more strict safety requirements for digital safety display system. To satisfy these requirements, it is necessary to develop a safety-critical (SIL 4) grade safety display system. This paper proposes industrial personal computer based safety display system with safety grade operating system and safety grade display methods. The description consists of three parts, the background, the safety requirements and the proposed safety display system design. The hardware platform is designed using commercially available off-the-shelf processor board with back plane bus. The operating system is customized for nuclear safety display application. The display unit is designed adopting two improvement features, i.e., one is to provide two separate processors for main computer and display device using serial communication, and the other is to use Digital Visual Interface between main computer and display device. In this case the main computer uses minimized graphic functions for safety display. The display design is at the conceptual phase, and there are several open areas to be concreted for a solid system. The main purpose of this paper is to describe and suggest a methodology to develop a safety-critical display system and the descriptions are focused on the safety requirement point of view

    The 3D display based on a parallax barrier is a low-cost autostereoscopic display. However, the vertical and horizontal resolution of the 3D images displayed on it will be seriously nonuniform as this display has a large number of views. It will worsen the display quality; therefore, a 3D display that consists of a 2D display panel and dual parallax barriers is proposed. With a 2D display panel, the proposed 3D display provides the synthetic images with square pixel units in which the arrangement of pixels can make the 3D image have uniform resolution. With the dual parallax barriers, the proposed 3D display shows the pixels in square pixel units for different horizontal views. Therefore, this display has uniform resolution of 3D images. A four-view prototype of the proposed 3D display is developed, and it provides uniform 3D resolution in the vertical and horizontal directions.

    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.

    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

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

    Holm, Andrej; Kuhn, Armin

    2011-01-01

    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 LHCb Event Display was made for educational purposes at the European Organization for Nuclear Research, CERN in Geneva, Switzerland. The project was implemented as a stand-alone application using C++ and ROOT, a framework developed by CERN for data analysis. This paper outlines the development and architecture of the application in detail, as well as the motivation for the development and the goals of the exercise. The application focuses on the visualization of events recorded by the LHCb detector, where an event represents a set of charged particle tracks in one proton-proton collision. Every particle track is coloured by its type and can be selected to see its essential information such as mass and momentum. The application allows students to save this information and calculate the invariant mass for any pair of particles. Furthermore, the students can use additional calculating tools in the application and build up a histogram of these invariant masses. The goal for the students is to find a $D^0$ par...

    Jefferson Lab's Web Extensible Display Manager (WEDM) allows staff to access EDM control system screens from a web browser in remote offices and from mobile devices. Native browser technologies are leveraged to avoid installing and managing software on remote clients such as browser plugins, tunnel applications, or an EDM environment. Since standard network ports are used firewall exceptions are minimized. To avoid security concerns from remote users modifying a control system, WEDM exposes read-only access and basic web authentication can be used to further restrict access. Updates of monitored EPICS channels are delivered via a Web Socket using a web gateway. The software translates EDM description files (denoted with the edl suffix) to HTML with Scalable Vector Graphics (SVG) following the EDM's edl file vector drawing rules to create faithful screen renderings. The WEDM server parses edl files and creates the HTML equivalent in real-time allowing existing screens to work without modification. Alternatively, the familiar drag and drop EDM screen creation tool can be used to create optimized screens sized specifically for smart phones and then rendered by WEDM.

  20. Three-dimensional volumetric display by inclined-plane scanning

    Miyazaki, Daisuke; Eto, Takuma; Nishimura, Yasuhiro; Matsushita, Kenji

    2003-05-01

    A volumetric display system based on three-dimensional (3-D) scanning that uses an inclined two-dimensional (2-D) image is described. In the volumetric display system a 2-D display unit is placed obliquely in an imaging system into which a rotating mirror is inserted. When the mirror is rotated, the inclined 2-D image is moved laterally. A locus of the moving image can be observed by persistence of vision as a result of the high-speed rotation of the mirror. Inclined cross-sectional images of an object are displayed on the display unit in accordance with the position of the image plane to observe a 3-D image of the object by persistence of vision. Three-dimensional images formed by this display system satisfy all the criteria for stereoscopic vision. We constructed the volumetric display systems using a galvanometer mirror and a vector-scan display unit. In addition, we constructed a real-time 3-D measurement system based on a light section method. Measured 3-D images can be reconstructed in the 3-D display system in real time.

    1997-11-01

    Projection systems continue to be the best method to produce large (1 meter and larger) displays. However, in order to produce a large display, considerable volume is typically required. The Polyplanar Optic Display (POD) is a novel type of projection display screen, which for the first time, makes it possible to produce a large projection system that is self-contained and only inches thick. In addition, this display screen is matte black in appearance allowing it to be used in high ambient light conditions. This screen is also interactive and can be remotely controlled via an infrared optical pointer resulting in mouse-like control of the display. Furthermore, this display need not be flat since it can be made curved to wrap around a viewer as well as being flexible.

  2. Augmenting digital displays with computation

    Science.gov (United States)

    Liu, Jing

    As we inevitably step deeper and deeper into a world connected via the Internet, more and more information will be exchanged digitally. Displays are the interface between digital information and each individual. Naturally, one fundamental goal of displays is to reproduce information as realistically as possible since humans still care a lot about what happens in the real world. Human eyes are the receiving end of such information exchange; therefore it is impossible to study displays without studying the human visual system. In fact, the design of displays is rather closely coupled with what human eyes are capable of perceiving. For example, we are less interested in building displays that emit light in the invisible spectrum. This dissertation explores how we can augment displays with computation, which takes both display hardware and the human visual system into consideration. Four novel projects on display technologies are included in this dissertation: First, we propose a software-based approach to driving multiview autostereoscopic displays. Our display algorithm can dynamically assign views to hardware display zones based on multiple observers' current head positions, substantially reducing crosstalk and stereo inversion. Second, we present a dense projector array that creates a seamless 3D viewing experience for multiple viewers. We smoothly interpolate the set of viewer heights and distances on a per-vertex basis across the arrays field of view, reducing image distortion, crosstalk, and artifacts from tracking errors. Third, we propose a method for high dynamic range display calibration that takes into account the variation of the chrominance error over luminance. We propose a data structure for enabling efficient representation and querying of the calibration function, which also allows user-guided balancing between memory consumption and the amount of computation. Fourth, we present user studies that demonstrate that the ˜ 60 Hz critical flicker fusion

    1995-12-31

    A 10 inch laser illuminated flat panel Planar Optic Display (POD) screen has been constructed and tested. This POD screen technology is an entirely new concept in display technology. Although the initial display is flat and made of glass, this technology lends itself to applications where a plastic display might be wrapped around the viewer. The display screen is comprised of hundreds of planar optical waveguides where each glass waveguide represents a vertical line of resolution. A black cladding layer, having a lower index of refraction, is placed between each waveguide layer. Since the cladding makes the screen surface black, the contrast is high. The prototype display is 9 inches wide by 5 inches high and approximately I inch thick. A 3 milliwatt HeNe laser is used as the illumination source and a vector scanning technique is employed.

    With quickly advance of the computer, microelectronics and photonics technologies, LED display panel becomes a new electronic advertising media. It can be used to show any information whatever characters or graphics. Most LED display panels are built of many Light-Emitting Diodes arranged in a matrix form. The display has many advantages such as low power, low cost, long life and high definition. Because the display panel is asked to show rich color, the LED display panel's driving system becomes very complex. The design methodology of LED display panel's driver becomes more and more important to meet the market requirements. Cost is always the most important issue in public market domain. In this paper, we report a design methodology of LED display panel's driver based on the microprocessor control unit (MCU) system and LED display controller IC, HT1632C, to control three colors, RGB, color LED display panel and the modular panel size is 24*16 in matrix form. The HT1632C is a memory mapping LED display controller, it can be used on many applications, such as digital clock, thermometer, counter, voltmeter or other instrumentation readouts. Three pieces of HT1632C are used to drive a 24*16 RGB LED display panel, in our design case. Each HT163C chip is used to control one of the R, G and B color. As the drive mode is driven in DC mode, the RGB display panel can create and totally of seven colors under the control of MCU. The MCU generates the control signal to drive HT1632C. In this study, the software design methodology is adopted with dynamic display principle. When the scan frequency is 60Hz, LED display panel will get the clear picture and be able to display seven colors.

    CLIPS is being used as an integral module of a rapid prototyping system. The prototyping system consists of a display manager for object browsing, a graph program for displaying line and bar charts, and a communications server for routing messages between modules. A CLIPS simulation of a physical model provides dynamic control of the user's display. Currently, a project is well underway to prototype the Advanced Automation System (AAS) for the Federal Aviation Administration.

    It is very difficult to make a liquid crystal display (LCD) that is flexible. However, for an optically re-writable LCD (ORWLCD), only the spacers and the substrates need to be flexible because the driving unit and the display unit are separate and there are no electronics in the display part of ORWLCD. In this paper, three flexible-spacer methods are proposed to achieve this goal. A cholesteric liquid crystal colored mirror with a polarizer behind it is used as the colored reflective backboard of an ORWLCD. Polyethersulfone substrates and flexible spacers are used to make the optically re-writable cell insensitive to mechanical force.

    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.

    2008-07-01

    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.

    2004-01-01

    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...

    2006-01-01

    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.

  16. 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.

  17. Measures of social segregation in the context of Warsaw, Berlin and Paris metropolitan areas

    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.

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

    Monika Grubbauer

    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.

    2013-09-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Langner, Marcel

    2014-04-01

    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.

  7. Machines to support motor rehabilitation after stroke: 10 years of experience in Berlin.

    Hesse, Stefan; Schmidt, Henning; Werner, Cordula

    2006-01-01

    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.

  9. Wild growing mushrooms for the Edible City? Cadmium and lead content in edible mushrooms harvested within the urban agglomeration of Berlin, Germany

    International Nuclear Information System (INIS)

    Schlecht, Martin Thomas; Säumel, Ina

    2015-01-01

    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. - Highlights: • Popular edible mushrooms display large variations in Cd and Pb content. • Low accumulating species are Sparassis crispa, Boletus luridus, or Boletus badius. • High accumulating species are Agaricus ssp., Russula vesca, or Calvatia gigantea. • Cd and Pb content in wild growing edible mushrooms were mostly above EU limits for cultivated mushrooms. • Cd and Pb content in commercial mushrooms cultures were regularly below EU limits for cultivated mushrooms. - Commercial mushroom cultures can be integrated into ‘Edible City’ approaches, but majority of wild growing mushroom samples highly accumulate trace metals

    2018-01-01

    A shape-changing table-top display with haptic feedback allows its users to perceive 3D visual and texture displays interactively. Since few existing devices are developed as accurate displays with regulatory haptic feedback, a novel attentive and immersive shape changing mechanical interface (SCMI) consisting of image processing unit and transformation unit was proposed in this paper. In order to support a precise 3D table-top display with an offset of less than 2 mm, a custommade mechanism was developed to form precise surface and regulate the feedback force. The proposed image processing unit was capable of extracting texture data from 2D picture for rendering shape-changing surface and realizing 3D modeling. The preliminary evaluation result proved the feasibility of the proposed system.

    1996-02-01

    Electronic visual displays have been evolving from the 1960's basis of cathode ray tube (CRT) technology. Now, many other technologies are also available, including both flat panels and projection displays. Standards for these displays are being developed at both the national level and the international levels. Standards activity within the United States is in its infancy and is fragmented according to the inclination of each of the standards developing organizations. The latest round of flat panel display technology was primarily developed in Japan. Initially standards arose from component vendor-to-OEM customer relationships. As a result, Japanese standards for components are the best developed. The Electronics Industries Association of Japan (EIAJ) is providing their standards to the International Electrotechnical Commission (IEC) for adoption. On the international level, professional societies such as the human factors society (hfs) and the International Organization for Standardization (ISO) have completed major standards, hfs developed the first ergonomic standard hfs-100 and the ISO has developed some sections of a broader ergonomic standard ISO 9241. This paper addresses the organization of standards activity. Active organizations and their areas of focus are identified. The major standards that have been completed or are in development are described. Finally, suggestions for improving the this standards activity are proposed.

    Objective The aim of this study was to determine control/display stereotypes for children of a range of ages and development of these stereotypes with age. Background Little is known about control/display stereotypes for children of different ages and the way in which these stereotypes develop with age. This study is part of a program to determine the need to design differentially for these age groups. Method We tested four groups of children with various tasks (age groups 5 to 7, 8 to 10, 11 to 13, 14 to 16), with about 30 in each group. Examples of common tasks were opening a bottle, turning on taps, and allocating numbers to keypads. More complex tasks involved rotating a control to move a display in a requested direction. Results Tasks with which different age groups were familiar showed no effect of age group. Different control/display arrangements generally showed an increase in stereotype strength with age, with dependence on the form of the control/display arrangement. Two-dimensional arrangements, with the control on the same plane as the display, had higher stereotype strength than three-dimensional arrangements for all age groups, suggesting an effect of familiarity with controls and displays with increasing age. Conclusion Children's control/display stereotypes do not differ greatly from those of adults, and hence, design for children older than 5 years of age, for control/display stereotypes, can be the same as that for adult populations. Application When designing devices for children, the relationship between controls and displays can be as for adult populations, for which there are considerable experimental data.

    A prototype embedded avionics system has been designed for the next generation of NASA extra-vehicular-activity (EVA) spacesuits. The system performs biomedical and other sensor monitoring, image capture, data display, and data transmission. An existing NASA Phase I and II award winning design for an embedded computing system (ZIN vMetrics - BioWATCH) has been modified. The unit has a reliable, compact form factor with flexible packaging options. These innovations are significant, because current state-of-the-art EVA spacesuits do not provide capability for data displays or embedded data acquisition and management. The Phase 1 effort achieved Technology Readiness Level 4 (high fidelity breadboard demonstration). The breadboard uses a commercial-grade field-programmable gate array (FPGA) with embedded processor core that can be upgraded to a space-rated device for future revisions.

    The era of the shuttle program has come to an end, but only to give rise to newer and more exciting projects. Now is the time of the Orion spacecraft, a work of art designed to exceed all previous endeavors of man. NASA is exiting the time of exploration and is entering a new period, a period of pioneering. With this new mission, many of NASAs organizations must undergo a great deal of change and development to support the Orion missions. The Spaceport Command and Control System (SCCS) is the new system that will provide NASA the ability to launch rockets into orbit and thus control Orion and other spacecraft as the goal of populating Mars becomes ever increasingly tangible. Since the previous control system, Launch Processing System (LPS), was primarily designed to launch the shuttles, SCCS was needed as Kennedy Space Center (KSC) reorganized to a multiuser spaceport for commercial flights, providing a more versatile control over rockets. Within SCCS, is the Launch Control System (LCS), which is the remote software behind the command and monitoring of flight and ground system hardware. This internship at KSC has involved two main components in LCS, including Remote Software Application and Display development. The display environment provides a graphical user interface for an operator to view and see if any cautions are raised, while the remote applications are the backbone that communicate with hardware, and then relay the data back to the displays. These elements go hand in hand as they provide monitoring and control over hardware and software alike from the safety of the Launch Control Center. The remote software applications are written in Application Control Language (ACL), which must undergo unit testing to ensure data integrity. This paper describes both the implementation and writing of unit tests in ACL code for remote software applications, as well as the building of remote displays to be used in the Launch Control Center (LCC).

    2015-01-01

    Two experiments are reported that were designed to investigate control/display arrangements having high stereotype strengths when using circular displays. Eight display locations relative to the operator and control were tested with rotational and translational controls situated on different planes according to the Frame of Reference Transformation Tool (FORT) model of Wickens et al. (2010). (Left. No, Right! Development of the Frame of Reference Transformation Tool (FORT), Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting, 54: 1022-1026). In many cases, there was little effect of display locations, indicating the importance of the Worringham and Beringer (1998. Directional stimulus-response compatibility: a test of three alternative principles. Ergonomics, 41(6), 864-880) Visual Field principle and an extension of this principle for rotary controls (Hoffmann and Chan (2013). The Worringham and Beringer 'visual field' principle for rotary controls. Ergonomics, 56(10), 1620-1624). The initial indicator position (12, 3, 6 and 9 o'clock) had a major effect on control/display stereotype strength for many of the six controls tested. Best display/control arrangements are listed for each of the different control types (rotational and translational) and for the planes on which they are mounted. Data have application where a circular display is used due to limited display panel space and applies to space-craft, robotics operators, hospital equipment and home appliances. Practitioner Summary: Circular displays are often used when there is limited space available on a control panel. Display/control arrangements having high stereotype strength are listed for four initial indicator positions. These arrangements are best for design purposes.

    A Planar Optic Display (POD) is being built and tested for suitability as a high brightness replacement for the cathode ray tube, (CRT). The POD display technology utilizes a laminated optical waveguide structure which allows a projection type of display to be constructed in a thin (I to 2 inch) housing. Inherent in the optical waveguide is a black cladding matrix which gives the display a black appearance leading to very high contrast. A Digital Micromirror Device, (DMD) from Texas Instruments is used to create video images in conjunction with a 100 milliwatt green solid state laser. An anamorphic optical system is used to inject light into the POD to form a stigmatic image. In addition to the design of the POD screen, we discuss: image formation, image projection, and optical design constraints.

    In many cockpits, control display units (CDUs) are vital input and information devices. In order to improve the usability of these devices, Barco, in cooperation with TU-Delft, created a touch screen control unit (TSCU), consisting of a high-quality multi-touch screen. The unit fits in the standard dimensions of a conventional CDU and is thus suitable for both retrofit and new installations. The TSCU offers two major advantages. First, the interface can be reconfigured to enable consecutive e...

    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.

    This paper proposes a wide color gamut approach that uses white and emerald lighting units as the backlight of the liquid crystal display. The white and emerald backlights are controlled by the image to be displayed. The mixing ratio of the white and the emerald lighting is analyzed so that the maximal color gamut coverage ratio can be achieved. Experimental results prove the effectiveness of the wide color gamut approach using white and emerald backlights.

  9. 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.

  10. 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.

  11. Tertiary treatment of Berlin WWTP effluents with ferrate (Fe(VI)).

    2013-01-01

    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.

    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.

    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.

    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.

    Witte, Wilfried

    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".

    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.

  11. 3D thermohydraulic modeling of the coupling of surface water bodies to the subsurface below the major urban center of Berlin

    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

    Conventional medical expert systems deliver advice as text (a diagnosis, list, recommendation, or discussion). This may be quite useful in some areas of medical decision making but has distinct limitations in such a visually oriented discipline as diagnostic imaging, where decisions often depend on pattern recognition and the appreciation of subtle morphologic features. We are developing an expert system that displays groups of images as part of its intelligent output. This system uses a rule-based strategy to select images for display. They may be displayed because they share a common feature, cluster of features, or clinical history. Such a system may be useful as a diagnostic aid or for continuing medical education. It is likely to have particular value in the setting of picture archiving and communication systems

    A new three-dimensional display system based on a volume-scanning method is demonstrated. To form a three-dimensional real image, an inclined two-dimensional image is rapidly moved with a mirror scanner while the cross-section patterns of a three-dimensional object are displayed sequentially. A vector-scan CRT display unit is used to obtain a high-resolution image. An optical scanning system is constructed with concave mirrors and a galvanometer mirror. It is confirmed that three-dimensional images, formed by the experimental system, satisfy all the criteria for human stereoscopic vision.

    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

    The Single Event Display (SED) is a routine that is designed to provide information graphically about a triggered event within the Crystal Ball. The SED is written entirely in FORTRAN and uses the CERN-based HICZ graphing package. The primary display shows the amount of energy deposited in each of the NaI crystals on a Mercator-like projection of the crystals. Ten different shades and colors correspond to varying amounts of energy deposited within a crystal. Information about energy clusters is displayed on the crystal map by outlining in red the thirteen (or twelve) crystals contained within a cluster and assigning each cluster a number. Additional information about energy clusters is provided in a series of boxes containing useful data about the energy distribution among the crystals within the cluster. Other information shown on the event display include the event trigger type and data about π o 's and η's formed from pairs of clusters as found by the analyzer. A description of the major features is given, along with some information on how to install the SED into the analyzer

    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

    The current Johnson Space Center (JSC) Mission Control Center (MCC) Video Transport System (VTS) provides flight controllers and management the ability to meld raw video from various sources with telemetry to improve situational awareness. However, maintaining a separate infrastructure for video delivery and integration of video content with data adds significant complexity and cost to the system. When considering alternative architectures for a VTS, the current system's ability to share specific computer displays in their entirety to other locations, such as large projector systems, flight control rooms, and back supporting rooms throughout the facilities and centers must be incorporated into any new architecture. Internet Protocol (IP)-based systems also support video delivery and integration. IP-based systems generally have an advantage in terms of cost and maintainability. Although IP-based systems are versatile, the task of sharing a computer display from one workstation to another can be time consuming for an end-user and inconvenient to administer at a system level. The objective of this paper is to present a prototype display sharing enterprise solution. Display sharing is a system which delivers image sharing across the LAN while simultaneously managing bandwidth, supporting encryption, enabling recovery and resynchronization following a loss of signal, and, minimizing latency. Additional critical elements will include image scaling support, multi -sharing, ease of initial integration and configuration, integration with desktop window managers, collaboration tools, host and recipient controls. This goal of this paper is to summarize the various elements of an IP-based display sharing system that can be used in today's control center environment.

    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.

    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.

  19. Effect of VOC Emissions from Vegetation on Air Quality in Berlin during a Heatwave.

    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.

  3. Reflective Cholesteric Liquid Crystal Displays.

    Science.gov (United States)

    Lu, Zhijian

    Reflective cholesteric displays have two states at zero field, a Bragg reflecting planar texture and a weakly scattering focal conic texture. The performance of such a display depends on the stability and optical property of these textures. In this dissertation, various surface alignment layers are studied in order to optimize display performance and to understand physical and optical properties. Results show that non-homogeneous alignment layers fracture the planar texture and produce a multidomain structure as well as stabilize the focal conic texture. In the multidomain structure, the orientations of helical axes are distributed about the normal of the display cell, resulting in a wide viewing angle. The reflecting properties of the multidomain planar texture are quantitatively modeled using Berreman's 4 x 4 formalism. A gaussian type function adequately describe the helical axis orientation distribution. When the alignment condition is varied from tangential to homeotropic, the orientation of the helical axes becomes more broadly distributed. Reflective displays with high contrast ratios and wide viewing angles are achieved by using tilted or homeotropic alignment layers. The switching mechanism between the two stable textures of the reflective displays is of great importance not only for designing drive scheme but also for understanding the fundamental dynamics of the texture transitions. Planar texture can be transformed into focal conic texture directly by applying a relatively low field. The transition from focal conic to planar texture can only be realized by first switching the cholesteric liquid crystals into the homeotropic texture and then allowing the homeotropic texture to relax to the planar texture. In the relaxation, a transient planar texture with pitch, {K_{33 }over K_{22}}P_ {o} is observed by using optical reflection measurement. The transition time from the homeotropic texture to the transient planar texture is on the order of 1 ms and is

    In many cockpits, control display units (CDUs) are vital input and information devices. In order to improve the usability of these devices, Barco, in cooperation with TU-Delft, created a touch screen control unit (TSCU), consisting of a high-quality multi-touch screen. The unit fits in the standard dimensions of a conventional CDU and is thus suitable for both retrofit and new installations. The TSCU offers two major advantages. First, the interface can be reconfigured to enable consecutive execution of several tasks on the same display area, allowing for a more efficient usage of the limited display real-estate as well as a potential reduction of cost. Secondly, advanced graphical interface design, in combination with multi-touch gestures, can improve human-machine interaction. To demonstrate the capabilities of this concept, a graphical software application was developed to perform the same operations as a conventional CDU, but now using a direct manipulation interface (DMI) of the displayed graphics. The TSCU can still be used in a legacy CDU mode, displaying a virtual keyboard operated with the touch interface. In addition, the TSCU could be used for a variety of other cockpit functions. The paper concludes with a report of pilot and non-pilot feedback.

    Augmented reality has become important to our society as it can enrich the actual world with virtual information. Transparent screens offer one possibility to overlay rendered scenes with the environment, acting both as display and window. In this work, we review existing transparent back-projection screens for the use with active and passive stereo. Advantages and limitations are described and, based on these insights, a passive stereoscopic system using an anisotropic back-projection foil is proposed. To increase realism, we adapt rendered content to the viewer's position using a Kinect tracking system, which adds motion parallax to the binocular cues. A technique well known in control engineering is used to decrease latency and increase frequency of the tracker. Our transparent stereoscopic display prototype provides immersive viewing experience and is suitable for many augmented reality applications.

    Medical illustration is a field of visual communication with a long history. Traditional medical illustrations are static, 2-D, printed images; highly realistic depictions of the gross morphology of anatomical structures. Today medicine requires the visualization of structures and processes that have never before been seen. Complex 3-D spatial relationships require interpretation from 2-D diagnostic imagery. Pictures that move in real time have become clinical and research tools for physicians. Medical illustrators are involved with the development of interactive visual displays for three different, but not discrete, functions: as educational materials, as clinical and research tools, and as data bases of standard imagery used to produce visuals. The production of interactive displays in the medical arts is examined.

    2014-02-01

    While virtual reality and digital games share many core technologies, the programming environments, toolkits, and workflows for developing games and VR environments are often distinct. VR toolkits designed for applications in visualization and simulation often have a different feature set or design philosophy than game engines, while popular game engines often lack support for VR hardware. Extending a game engine to support systems such as the CAVE gives developers a unified development environment and the ability to easily port projects, but involves challenges beyond just adding stereo 3D visuals. In this paper we outline the issues involved in adapting a game engine for use with an immersive display system including stereoscopy, tracking, and clustering, and present example implementation details using Unity3D. We discuss application development and workflow approaches including camera management, rendering synchronization, GUI design, and issues specific to Unity3D, and present examples of projects created for a multi-wall, clustered, stereoscopic display.

    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 aim of the study was to assess the effect of rubber mats in service unit on displaying stereotypies in gilts. Four 28-day production cycles in all seasons were observed. Each cycle included 28 gilts housed in gestation stalls with slatted concrete floor, which was covered with adjusted mats for 14 gilts (experimental group), while the remaining 14 gilts served as controls. Display of stereotypies and other behaviours observed, mat manipulation and postural behaviours were estimated by direct 1-hour observation of gilts at 2-minute intervals after morning feed supply on days 1, 8, 15 and 28 of each cycle. During the study period, displaying stereotypies was significantly less frequent (P gilts in the conditions of lower air temperature. During the cold period, experimental gilts took a lying position significantly more frequently (P gilts there was no significant correlation (P > 0.05 all) between the frequency of displaying stereotypies and the frequency of lying and other postures observed, as well as between the stereotypy display and the air temperature. There was no significant correlation (P > 0.05 all) between the frequency of mat manipulation and displaying stereotypies in total or its particular forms, suggesting that the less pronounced stereotypy display in experimental gilts may have been influenced by factors other than those observed in the present study.

    The focus of this project was to investigate the factors influencing consumer adoption of Home Energy Displays (HEDs) and to evaluate electricity consumption in households with basic HEDs versus enhanced feedback methods - web portals or alerts. We hypothesized that providing flexible and relatable information to users, in addition to a basic HED, would make feedback more effective and achieve persistent energy savings. In Phase I, we conducted three user research studies and found preferences for aesthetically pleasing, easy to understand feedback that is accessible through multiple media and offered free of charge. The deployment of HEDs in 150 households planned for Phase II encountered major recruitment and HED field deployment problems. First, after extensive outreach campaigns to apartment complexes with 760 units, only 8% of building's tenants elected to receive a free HED in their homes as part of the field study. Second, the HED used, a leading market model, had a spectrum of problems, including gateway miscommunications, failure to post to a data-hosting third party, and display malfunctions. In light of these challenges, we are pursuing a modified study investigating the energy savings of a web portal versus alert-based energy feedback instead of a physical HED.

    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.

  16. Modeling the fate of organic micropollutants during river bank filtration (Berlin, Germany).

    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

    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.

    monochrome, it is possible to create an RGB-display. For the same reasons we started tests with polymers. We were able to achieve meaningful results which point out a new direction in the investigation on polymers. For the reasons described above, our new solid state device is one of modular design. The simplicity to change all components makes it possible to do experiments with different display volumes and lasers for every specific purpose of the display in a very effective way. The images can be drawn inside the display volume by acousto-optic, galvanometric or polygon mirror deflection units. We control our galvanometric deflection unit with a personal computer and a selfwritten software which makes it easier to handle the setup and makes interactivity possible. This setup makes it a powerful and flexible tool to keep track with the rapid technological progress of today and helped us to experience the disadvantages and the advantages of most of the possible deflection units in practice. These experiences are a main element in our paper and lead to some conclusions which will be of big importance in future display developments. Potential applications include imaging and computer aided design as well as scientific data visualization.

    The Parameter Display Page program (DP) is a Motif/X11-based program to allow easily configured, dynamic device and process variable monitoring and manipulation in the EPICS environment. DP provides a tabular data format for interactive viewing and manipulation of device and process variable statistics, as well as formatted PostScript output to files and printers. DP understands and operates in two (unfortunately disjoint at this time) namespaces in the EPICS environment ''devices'' and ''process variables''. The higher level namespace of devices includes Composite and Atomic Devices registered via the Device Access server; the lower level (flat) namespace is that of normal Process Variables accessible via Channel Access

    Nuclear medicine imaging studies involve evaluation of a large amount of image data. Digital signal processing techniques have introduced processing algorithms that increase the information content of the display. Nuclear medicine imaging studies require interactive selection of suitable form of display and pre-display processing. Static imaging study requires pre-display processing to detect focal defects. Point operations (histogram modification) along with zoom and capability to display more than one image in one screen is essential. This album mode of display is also applicable to dynamic, MUGA and SPECT data. Isometric display or 3-D graph of the image data is helpful in some cases e.g. point spread function, flood field data. Cine display is used on a sequence of images e.g. dynamic, MUGA and SPECT imaging studies -to assess the spatial movement of tracer with time. Following methods are used at the investigator's discretion for inspection of the 3-D object. 1) Display of orthogonal projections, 2) Display of album of user selected coronal/ sagital/ transverse orthogonal slices, 3) Display of three orthogonal slices through user selected point, 4) Display of a set of orthogonal slices generated in the user-selected volume, 5) Generation and display of 3-D shaded surface. 6) Generation of volume data and display along with the 3-D shaded surface, 7) Side by side display orthogonal slices of two 3-D objects. Displaying a set of two-dimensional slices of a 3-D reconstructed object through shows all the defects but lacks the 3-D perspective. Display of shaded surface lacks the ability to show the embedded defects. Volume display -combining the 3-D surface and gray level volume data is perhaps the best form of display. This report describes these forms of display along with the theory. (author)

    The final step in a medical imaging procedure is to display the image(s) on a suitable display system where it is presented to the medical specialist for diagnostic interpretation. The display of hard copy images on X ray film or photographic film has largely been replaced today by soft copy image display systems with cathode ray tube (CRT) or liquid crystal display (LCD) monitors as the image rendering device. Soft copy display requires a high quality display monitor and a certain amount of image processing to optimize the image both with respect to the properties of the display device and to some psychophysiological properties of the human visual system. A soft copy display system, therefore, consists of a display workstation providing some basic image processing functions and the display monitor as the intrinsic display device. Display devices of lower quality may be used during intermediate steps of the acquisition and analysis of a patient study. Display monitors with a quality suitable for diagnostic reading by the specialist medical doctor are called primary devices, also known as diagnostic devices. Monitors with lower quality but good enough to be used for positioning, processing of studies, presentation of images in the wards, etc. are referred to as secondary devices or clinical devices. Nuclear medicine images can be adequately displayed even for diagnostic purposes on secondary devices. However, the increasing use of X ray images on which to report jointly with images from nuclear medicine studies, such as those generated by dual modality imaging, notably by positron emission tomography (PET)/computed tomography (CT) and single photon emission computed tomography (SPECT)/CT, requires display devices capable of visualizing high resolution grey scale images at diagnostic quality, i.e. primary display devices. Both grey scale and colour display devices are used, the latter playing an important role in the display of processed nuclear medicine images and

    1982-01-01

    Two computer programs have been developed which generate a two-dimensional graphic perspective of the video output produced by a Closed Circuit Television (CCTV) camera. Both programs were primarily written to produce a graphic display simulating the field-of-view (FOV) of a perimeter assessment system as seen on a CCTV monitor. The original program was developed for use on a Tektronix 4054 desktop computer; however, the usefulness of this graphic display program led to the development of a similar program for a Hewlett-Packard 9845B desktop computer. After entry of various input parameters, such as, camera lens and orientation, the programs automatically calculate and graphically plot the locations of various items, e.g., fences, an assessment zone, running men, and intrusion detection sensors. Numerous special effects can be generated to simulate such things as roads, interior walls, or sides of buildings. Other objects can be digitized and entered into permanent memory similar to the running men. With this type of simulated monitor perspective, proposed camera locations with respect to fences and a particular assessment zone can be rapidly evaluated without the costly time delays and expenditures associated with field evaluation

    In this work we addressed the problem how to fabricate self-assembling tubular nanostructures displaying target recognition functionalities. Bacterial flagellar filaments, composed of thousands of flagellin subunits, were used as scaffolds to display single-domain antibodies (nanobodies) on their surface. As a representative example, an anti-GFP nanobody was successfully inserted into the middle part of flagellin replacing the hypervariable surface-exposed D3 domain. A novel procedure was developed to select appropriate linkers required for functional internal insertion. Linkers of various lengths and conformational properties were chosen from a linker database and they were randomly attached to both ends of an anti-GFP nanobody to facilitate insertion. Functional fusion constructs capable of forming filaments on the surface of flagellin-deficient host cells were selected by magnetic microparticles covered by target GFP molecules and appropriate linkers were identified. TEM studies revealed that short filaments of 2-900 nm were formed on the cell surface. ITC and fluorescent measurements demonstrated that the fusion protein exhibited high binding affinity towards GFP. Our approach allows the development of functionalized flagellar nanotubes against a variety of important target molecules offering potential applications in biosensorics and bio-nanotechnology.

    Boltzmann headstone S = kB Log W turns out to be the Rosette stone for Greek physics translation optical display of the microwave sensing hieroglyphics. The LHS is the molecular entropy S measuring the degree of uniformity scattering off the sensing cross sections. The RHS is the inverse relationship (equation) predicting the Planck radiation spectral distribution parameterized by the Kelvin temperature T. Use is made of the conservation energy law of the heat capacity of Reservoir (RV) change T Δ S = -ΔE equals to the internal energy change of black box (bb) subsystem. Moreover, an irreversible thermodynamics Δ S > 0 for collision mixing toward totally larger uniformity of heat death, asserted by Boltzmann, that derived the so-called Maxwell-Boltzmann canonical probability. Given the zero boundary condition black box, Planck solved a discrete standing wave eigenstates (equation). Together with the canonical partition function (equation) an average ensemble average of all possible internal energy yielded the celebrated Planck radiation spectral (equation) where the density of states (equation). In summary, given the multispectral sensing data (equation), we applied Lagrange Constraint Neural Network (LCNN) to solve the Blind Sources Separation (BSS) for a set of equivalent bb target temperatures. From the measurements of specific value, slopes and shapes we can fit a set of Kelvin temperatures T's for each bb targets. As a result, we could apply the analytical continuation for each entropy sources along the temperature-unique Planck spectral curves always toward the RGB color temperature display for any sensing probing frequency.

    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.

    Full Text Available BACKGROUND: Autopsy rates in Western countries consistently decline to an average of <5%, although clinical autopsies represent a reasonable tool for quality control in hospitals, medically and economically. Comparing pre- and postmortal diagnoses, diagnostic discrepancies as uncovered by clinical autopsies supply crucial information on how to improve clinical treatment. The study aimed at analyzing current diagnostic discrepancy rates, investigating their influencing factors and identifying risk profiles of patients that could be affected by a diagnostic discrepancy. METHODS AND FINDINGS: Of all adult autopsy cases of the Charité Institute of Pathology from the years 1988, 1993, 1998, 2003 and 2008, the pre- and postmortal diagnoses and all demographic data were analyzed retrospectively. Based on power analysis, 1,800 cases were randomly selected to perform discrepancy classification (class I-VI according to modified Goldman criteria. The rate of discrepancies in major diagnoses (class I was 10.7% (95% CI: 7.7%-14.7% in 2008 representing a reduction by 15.1%. Subgroup analysis revealed several influencing factors to significantly correlate with the discrepancy rate. Cardiovascular diseases had the highest frequency among class-I-discrepancies. Comparing the 1988-data of East- and West-Berlin, no significant differences were found in diagnostic discrepancies despite an autopsy rate differing by nearly 50%. A risk profile analysis visualized by intuitive heatmaps revealed a significantly high discrepancy rate in patients treated in low or intermediate care units at community hospitals. In this collective, patients with genitourinary/renal or infectious diseases were at particularly high risk. CONCLUSIONS: This is the current largest and most comprehensive study on diagnostic discrepancies worldwide. Our well-powered analysis revealed a significant rate of class-I-discrepancies indicating that autopsies are still of value. The identified risk

    We present a novel typewriter application ‘Hex-o-Spell’ that is specifically tailored to the characteristics of direct brain-to-computer interaction. The high bandwidth at which a user may perceive information from the display is used in an appealing visualization based on hexagons. On the other hand the control of the application is possible at low bandwidth using only two control commands (mental states) and is relatively stable against delays and the like. The effectiveness and robustne...

    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.

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

    Frühauf, Tina

    2011-10-01

    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

    Despite the rapid development of cyber technologies, today we still have very limited attention and communication bandwidth to process the increasing information flow. The goal of the study is to develop a context-aware filter to match the information load with particular needs and capacities. The functions include bandwidth-resolution trade-off and user context modeling. From the empirical lab studies, it is found that the resolution of images can be reduced in order of magnitude if the viewer knows that he/she is looking for particular features. The adaptive display queue is optimized with real-time operational conditions and user's inquiry history. Instead of measuring operator's behavior directly, ubiquitous computing models are developed to anticipate user's behavior from the operational environment data. A case study of the video stream monitoring for transit security is discussed in the paper. In addition, the author addresses the future direction of coherent human-machine vision systems.

    Full Text Available Die Universitätsgründung in Berlin von 1810 war verbunden mit der Übernahme des Lehrbetriebes der aufgelösten Bergakademie, die nur noch in Form des Bergeleveninstituts bzw. Bergelevenklasse für die Finanzierung der Ausbildung der Bergeleven weiter bestand, sowie mit der Übernahme des von der Bergakademie genutzten Königlichen Mineralienkabinetts der preußischen Bergverwaltung als Mineralogisches Museum der Universität. 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. Der streitbare Charakter von Weiss verursachte zahlreiche Reibungspunkte. History of the Geoscience Institutes of the Natural History Museum in Berlin. Part 4 The establishment of the University in Berlin in 1810 resulted in the adoption of the teaching of the dissolved Bergakademie and of the royal Mineralienkabinett of the Prussian mining department, which was used by the Bergakademie before it became the Mineralogical Museum of the University. The Bergakademie continued to exist only as Bergeleveninstitut or Bergelevenklasse for financing the education of the mining students. The physicist and mineralogist C. S.

    2012-02-13

    This thesis aims to reduce the energy consumption as well as greenhouse gases to the environment without negatively affecting the thermal comfort. In the present work, thermal, energetic and economic impacts of employing passive solar systems combined with energy conservation systems have been investigated. These energy systems have been integrated with a typical residential building located in three different climate zones in Europe and Middle East regions.Hour-by-hour energy computer simulations have been carried out using TRNSYS and INSEL programs to analyze the performance of integrated energy systems. Furthermore, IESU software module has been developed to simulate a novel cooling unit using Phase Change Material (PCM). This unit is named as Indirect Evaporative and Storage Unit (IESU). Thereafter, complete economic equations for the Life Cycle Cost (LCC) criterion have been formulated. Furthermore this criterion has been optimized for different variables as a function of thermal parameters and economic figures from local markets. An optimum design of both residential buildings and energy systems has great impact on energy consumption. In fact, results showed that the energy consumption is reduced by 85.62%, 86.33% and 74.05% in Berlin, Amman and Aqaba, respectively. Moreover, the LCC criterion is reduced by 41.85% in Berlin, 19.21% in Amman and 15.22% in Aqaba.The macro economic analysis shows that once this research is applied in one million typical residential buildings in the selected climate zones, the annual avoided CO{sub 2} emissions are estimated to be about 5.7 million Tons in Berlin. In Aqaba, around 2.96 million Tons CO{sub 2} emissions will be saved annually and in Amman about 2.98 million Tons will be reduced. The payback period from the achieved saving is 18 years, 11 years and 8.6 years in Amman, Aqaba and Berlin, respectively.

    Today, process displays used in industry are often designed on the basis of piping and instrumentation diagrams without any method of ensuring that the needs of the operators are fulfilled. Therefore, a method for a systematic approach to the design of process displays is needed. This paper...... discusses aspects of process display design taking into account both the designer's and the operator's points of view. Three aspects are emphasized: the operator tasks, the display content and the display form. The distinction between these three aspects is the basis for proposing an outline for a display...... design method that matches the industrial practice of modular plant design and satisfies the needs of reusability of display design solutions. The main considerations in display design in the industry are to specify the operator's activities in detail, to extract the information the operators need from...

  7. Microprocessor based beam intensity and efficiency display system for the Fermilab accelerator

    International Nuclear Information System (INIS)

    Biwer, R.

    1979-01-01

    The Main Accelerator display system for the Fermilab accelerator gathers charge data and displays it including processed transfer efficiencies of each of the accelerators. To accomplish this, strategically located charge converters monitor the circulating internal beam of each of the Fermilab accelerators. Their outputs are processed via an asynchronously triggered, multiplexed analog-to-digital converter. The data is converted into a digital byte containing address code and data, then stores it into two 16-bit memories. One memory outputs the interleaved data as a data pulse train while the other interfaces directly to a local host computer for further analysis. The microprocessor based display unit synchronizes displayed data during normal operation as well as special storage modes. The display unit outputs data to the fron panel in the form of a numeric value and also makes digital-to-analog conversions of displayed data for external peripheral devices. 5 refs

    Full Text Available By investigating the processes by which successful teachers become activate citizens and by listening to the diversity and richness of their life and formation stories, this work became possible. Its aim is to display some of the utterances of two Down Syndrome individuals and their active-citizenship activities. Their stories were told in the reports of two teachers when describing their personal and professional history, and were considered to be an integral part of it. Thus, some of the utterances and perceptions with which these two individuals elaborate their references, their worldview and their active-citizenship activity are evidenced in this paper. This article is based on the language conceptions of Vygotsky and Bakhtin who defend the idea that the group and the social mentality are ingrain in the individual. Hence, the history of one person reveals that of many others, since there is a deep link between the individual and the social in the formation of a subjective worldview. As a result, it can be easily seen that the utterances expressed by the participants in this research cannot be considered strictly individual because enunciation is social in nature. Despite the fact that the utterances are those of individuals, they manifest a collective reality. This demonstrates the real advantages and possibilities that deficient people get from their participation and intervention in society.

    2012-07-01

    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.

    Full Text Available Die Öffentlichkeitsarbeit der Staatsbibliothek zu Berlin zielt auf eine wirksame Darstellung ihrer bibliothekarischen Weltschätze und ihrer Serviceangebote für die Wissenschaft ab. Sie ruht auf drei Säulen: kulturelle Breitenbildung für wenig bibliotheksaffine Kreise, allgemeine und breit gefächerte Öffentlichkeitsarbeit sowie Aktionen, die sich an spezielle communities in der Wissenschaft richten. 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.

    Urey, Hakan

    2000-06-01

    Virtual Retinal DisplayTM technology is a retinal scanning display (RSD) technology being developed at Microvision, Inc., for a variety of applications including microdisplays. An RSD scans a modulated light beam onto a viewer's retina to produce a perceived image. Red, green and blue light sources, such as lasers, laser diodes or LEDs combine with Microvision's proprietary miniaturized scanner designs to make the RSD very well suited for head-worn and helmet-mounted displays (HMD). This paper compares the features of RSD technology to other display technologies such as the cathode ray tubes or matrix-based displays for HMD and other wearable display applications, and notes important performance advantages due to the number of pixel- generating elements. Also discussed are some fundamental optical limitations for virtual displays used in the HMD applications.

    Toner Display is based on an electrical movement of charged particles. Two types of black toner and white particles charged in the different electric polarity are enclosed between two electrodes. The particle movement is controlled by the external electric field applied between two transparent electrodes. The toner is collected to the electrode by an electrostatic force across the insulating layer to display a black image. The toners can be put back to the counter electrode by applying a reverse electric field, and white solid image is displayed. We have studied on the movement of three color particles independently to display color image in Toner Display. Two positively charged color particles with different amount of charge to mass ratio and negatively charged white particles were enclosed in the toner display cell. Yellow, cyan and white images were displayed by an application of voltage.

    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.

  10. 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.

  11. Conceptual design of industrial process displays.

    Pedersen, C R; Lind, M

    1999-11-01

    Today, process displays used in industry are often designed on the basis of piping and instrumentation diagrams without any method of ensuring that the needs of the operators are fulfilled. Therefore, a method for a systematic approach to the design of process displays is needed. This paper discusses aspects of process display design taking into account both the designer's and the operator's points of view. Three aspects are emphasized: the operator tasks, the display content and the display form. The distinction between these three aspects is the basis for proposing an outline for a display design method that matches the industrial practice of modular plant design and satisfies the needs of reusability of display design solutions. The main considerations in display design in the industry are to specify the operator's activities in detail, to extract the information the operators need from the plant design specification and documentation, and finally to present this information. The form of the display is selected from existing standardized display elements such as trend curves, mimic diagrams, ecological interfaces, etc. Further knowledge is required to invent new display elements. That is, knowledge about basic visual means of presenting information and how humans perceive and interpret these means and combinations. This knowledge is required in the systematic selection of graphical items for a given display content. The industrial part of the method is first illustrated in the paper by a simple example from a plant with batch processes. Later the method is applied to develop a supervisory display for a condenser system in a nuclear power plant. The differences between the continuous plant domain of power production and the batch processes from the example are analysed and broad categories of display types are proposed. The problems involved in specification and invention of a supervisory display are analysed and conclusions from these problems are made. It is

    In the main control rooms of nuclear power plants, operators frequently have to switch between procedure displays and system information displays. In this study, we proposed an operation-unit-based integrated design, which combines the two displays to facilitate the synthesis of information. We grouped actions that complete a single goal into operation units and showed these operation units on the displays of system states. In addition, we used different levels of visual salience to highlight the current unit and provided a list of execution history records. A laboratory experiment, with 42 students performing a simulated procedure to deal with unexpected high pressuriser level, was conducted to compare this design against an action-based integrated design and the existing separated-displays design. The results indicate that our operation-unit-based integrated design yields the best performance in terms of time and completion rate and helped more participants to detect unexpected system failures. Practitioner Summary: In current nuclear control rooms, operators frequently have to switch between procedure and system information displays. We developed an integrated design that incorporates procedure information into system displays. A laboratory study showed that the proposed design significantly improved participants' performance and increased the probability of detecting unexpected system failures.

    2000-04-01

    Although analog CRTs continue to enable most of the world's electronic projection displays such as US consumer rear projection televisions, discrete pixel (digital) active matrix LCD and DLP reflective mirror array projectors have rapidly created large nonconsumer markets--primarily for business. Recent advances in image quality, compactness and cost effectiveness of digital projectors have the potential to revolutionize major consumer and entertainment markets as well. Digital penetration of the mainstream consumer projection TV market will begin in the hear 2000. By 2005 digital projection HDTVs could take the major share of the consumer HDTV projection market. Digital projection is expected to dominate both the consumer HDTV and the cinema market by 2010, resulting in potential shipments for all projection markets exceeding 10 M units per year. Digital projection is improving at a rate 10X faster than analog CRT projectors and 5X faster than PDP flat panels. Continued rapid improvement of digital projection is expected due to its relative immaturity and due to the wide diversity of technological improvements being pursued. Key technology enablers are the imaging panels, light sources and micro-optics. Market shares of single panel projectors, MEMs panels, LCOS panels and low T p-Si TFT LCD panel variants are expected to increase.

    2004-01-01

    Forecasters at the 45th Weather Squadron and Spaceflight Meteorology Group use data from the tower network over the Kennedy Space Center (KSC) and Cape Canaveral Air Force Station (CCAFS) to evaluate Launch Commit Criteria, and issue and verify forecasts for ground operations. Systematic biases in these parameters could adversely affect an analysis, forecast, or verification. Also, substantial geographical variations in temperature and wind speed can occur under specific wind directions. To address these concerns, the Applied Meteorology Unit (AMU) developed a climatology of temperatures and winds from the tower network, and identified the geographical variation and significant tower biases. The mesoclimate is largely driven by the complex land-water interfaces across KSC/CCAFS. Towers with close proximity to water typically had much warmer nocturnal temperatures and higher wind speeds throughout the year. The strongest nocturnal wind speeds occurred from October to March whereas the strongest mean daytime wind speeds occurred from February to May. These results of this project can be viewed by forecasters through an interactive graphical user interface developed by the AMU. The web-based interface includes graphical and map displays of mean, standard deviation, bias, and data availability for any combination of towers, variables, months, hours, and wind directions.

    A prominent issue for evaluating ambient displays has been the conflict between the relative intrusiveness of evaluation methods and the intention to keep the display at the periphery of the user’s attention. There is a general lack of research discussing the difficulties of evaluating ambient...... displays in the wild, and in particular social aspects of use has received little attention. This paper presents a case study of an ambient light display designed for a public setting. Based on results from a non-intrusive in situ evaluation, we argue that viewing ambient displays as features of a broader...... social setting may aid our understanding of issues regarding the evaluation of ambient displays in the wild....

    The Polyplanar Optical Display (POD) is a unique display screen which can be used with any projection source. This display screen is 2 inches thick and has a matte-black face which allows for high contrast images. The prototype being developed is a form, fit and functional replacement display for the B-52 aircraft which uses a monochrome ten-inch display. The new display uses a 200 milliwatt green solid-state laser (532 nm) as its optical source. In order to produce real-time video, the laser light is being modulated by a Digital Light Processing (DLP) chip manufactured by Texas Instruments, Inc. A variable astigmatic focusing system is used to produce a stigmatic image on the viewing face of the POD. In addition to the optical design, the authors discuss the DLP chip, the optomechanical design and viewing angle characteristics.

    2003-03-01

    Despite the dominance of liquid crystal displays, they do not perform some functions very well. While backlit liquid crystal displays can offer excellent color performance, they wash out in bright lighting and suffer from high power consumption. Reflective liquid crystal displays have limited brightness, making these devices challenging to read for long periods of time. Flexible liquid crystal displays are difficult to manufacture and keep stable. All of these attributes (long battery lifetime, bright reflective appearance, compatibility with flexible substrates) are traits that would be found in an ideal electronic paper display - an updateable substitute for paper that could be employed in electronic books, newspapers, and other applications. I will discuss technologies that are being developed for electronic-paper-like displays, and especially on particle-based technologies. A microencapsulated electrophoretic display technology is being developed at the E Ink corporation. This display film offers offer high brightness and an ink-on-paper appearance, compatibility with flexible substrates, and image stability that can lead to very low power consumption. I will present some of the physical and chemical challenges associated with making display films with high performance.

    Singh, B; Samuel, A M

    2002-01-01

    Nuclear medicine imaging studies involve evaluation of a large amount of image data. Digital signal processing techniques have introduced processing algorithms that increase the information content of the display. Nuclear medicine imaging studies require interactive selection of suitable form of display and pre-display processing. Static imaging study requires pre-display processing to detect focal defects. Point operations (histogram modification) along with zoom and capability to display more than one image in one screen is essential. This album mode of display is also applicable to dynamic, MUGA and SPECT data. Isometric display or 3-D graph of the image data is helpful in some cases e.g. point spread function, flood field data. Cine display is used on a sequence of images e.g. dynamic, MUGA and SPECT imaging studies -to assess the spatial movement of tracer with time. Following methods are used at the investigator's discretion for inspection of the 3-D object. 1) Display of orthogonal projections, 2) Disp...

    Chan, Alan H S; Hoffmann, Errol R

    2015-01-01

    Experiments were designed to investigate the effects of control type and display location, relative to the operator, on the strength of control/display stereotypes. The Worringham and Beringer Visual Field principle and an extension of this principle for rotary controls (Hoffmann E.R., and Chan A.H.S. 2013). "The Worringham and Beringer 'Visual Field' Principle for Rotary Controls. Ergonomics." 56 (10): 1620-1624) indicated that, for a number of different control types (rotary and lever) on different planes, there should be no significant effect of the display location relative to the seated operator. Past data were surveyed and stereotype strengths listed. Experiments filled gaps where data are not available. Six different control types and seven display locations were used, as in the Frame of Reference Transformation Tool (FORT) model of Wickens et al. (Wickens, C.D., Keller, J.W., and Small, R.L. (2010). "Left. No, Right! Development of the Frame of Reference Transformation Tool (FORT)." Proceedings of the Human Factors and Ergonomics Society 54th Annual Meeting September 2010, 54: 1022-1026). Control/display arrangements with high stereotype strengths were evaluated yielding data for designers of complex control/display arrangements where the control and display are in different planes and for where the operator is moving. It was found possible to predict display/control arrangements with high stereotype strength, based on past data. Practitioner Summary: Controls and displays in complex arrangements need to have high compatibility. These experiments provide arrangements for six different controls (rotary and translational) and seven different display locations relative to the operator.

    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).

    Three dimensional (3D) displays are critical for viewing complex multi-dimensional information and for viewing representations of the three dimensional real world. A teaming arrangement between Laser Power Corporation (LPC) and Specialty Devices, Inc. (SDI) has led to the feasibility demonstration of a directly-viewed three dimensional volumetric display. LPC has developed red, green, and blue (RGB) diode pumped solid state microlaser display technology for use as a high resolution, high brightness display engine for the three dimensional display. Concurrently, SDI has developed a unique technology for viewing high resolution three dimensional volumetric images without external viewing aids (eye wear). When coupled to LPC's display engine, the resultant all solid state three dimensional display presets a true, physical three dimensionality which is directly viewable from all angles by multiple viewers without additional viewing equipment (eye wear). The resultant volumetric display will further enable applications such as the 'virtual sandbox,' visualization of radar and sonar data, air traffic control, remote surgery and diagnostics, and CAD workstations.

    Rothe, Achim; Hosse, Ralf J; Power, Barbara E

    2006-02-01

    Ribosome display presents an innovative in vitro technology for the rapid isolation and evolution of high-affinity peptides or proteins. Displayed proteins are bound to and recovered from target molecules in multiple rounds of selection in order to enrich for specific binding proteins. No transformation step is necessary, which could lead to a loss of library diversity. A cycle of display and selection can be performed in one day, enabling the existing gene repertoire to be rapidly scanned. Proteins isolated from the panning rounds can be further modified through random or directed molecular evolution for affinity maturation, as well as selected for characteristics such as protein stability, folding and functional activity. Recently, the field of display technologies has become more prominent due to the generation of new scaffolds for ribosome display, isolation of high-affinity human antibodies by phage display, and their implementation in the discovery of novel protein-protein interactions. Applications for this technology extend into the broad field of antibody engineering, proteomics, and synthetic enzymes for diagnostics and therapeutics in cancer, autoimmune and infectious diseases, neurodegenerative diseases and inflammatory disorders. This review highlights the role of ribosome display in drug discovery, discusses advantages and disadvantages of the system, and attempts to predict the future impact of ribosome display technology on the development of novel engineered biopharmaceutical products for biological therapies.

    Vision researchers rely on visual display technology for the presentation of stimuli to human and nonhuman observers. Verifying that the desired and displayed visual patterns match along dimensions such as luminance, spectrum, and spatial and temporal frequency is an essential part of developing controlled experiments. With cathode-ray tubes (CRTs) becoming virtually unavailable on the commercial market, it is useful to determine the characteristics of newly available displays based on organic light emitting diode (OLED) panels to determine how well they may serve to produce visual stimuli. This report describes a series of measurements summarizing the properties of images displayed on two commercially available OLED displays: the Sony Trimaster EL BVM-F250 and PVM-2541. The results show that the OLED displays have large contrast ratios, wide color gamuts, and precise, well-behaved temporal responses. Correct adjustment of the settings on both models produced luminance nonlinearities that were well predicted by a power function (“gamma correction”). Both displays have adjustable pixel independence and can be set to have little to no spatial pixel interactions. OLED displays appear to be a suitable, or even preferable, option for many vision research applications. PMID:24155345

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.

    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

    The Liberty Science Center (LSC) is the largest (300,000 sq. ft.) education resource in the New Jersey -- New York City region. PPPL in collaboration with the LSC has had a display at the center since 2007 More than 1.5 million visitors have come to the museum since the plasma display has been introduced. The plasma display has had significant use during that time frame. During the summer of 2009 a redesigned plasma exhibit was created by a student teacher-team using the lessons learned from the existing exhibit. The display includes a DC glow discharge tube with a permanent external magnet allowing visitors to manipulate the plasma and see how plasma can be used for fusion research. The goal of the display is to allow an individual to see a plasma and understand the potential benefits of fusion energy.

    The development of an integrated digitizing and display surface, which utilizes touch entry and flat panel display (FPD) technology, is a significant hardware advance in the field of geographic information systems (GIS). Inherent qualities of the FPD, notably the ac gas plasma display, makes such a marriage inevitable. Large diagonal sizes, high resolution color, screen flatness, and monitor thickness are desirable features of an integrated digitizing and display surface. Recently, the GIS literature has addressed a need for such an innovation. The development of graphics displays based on sophisticated technologies include `photorealistic' (or high definition) imaging at resolutions of 2048 X 2048 or greater, palates of 16.7 million colors, formats greater than 30 inches diagonal, and integrated touch entry. In this paper, there is an evaluation of FPDs and data input technologies in the development of such a product.

    The Mirror Fusion Test Facility (MFTF) is controlled by 65 local control microcomputers which are supervised by a local network of nine 32-bit minicomputers. Associated with seven of the nine computers are state-of-the-art graphics devices, each with extensive local processing capability. These devices provide the means for an operator to interact with the control software running on the minicomputers. It is critical that the information the operator views accurately reflects the current state of the experiment. This information is integrated into dynamically changing pictures called displays. The primary organizational component of the display system is the software-addressable segment. The segments created by the display creation software are managed by display managers associated with each graphics device. Each display manager uses sophisticated storage management mechanisms to keep the proper segments resident in the local graphics device storage

    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.

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

    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

    The ubiquitousness of web clients from personal computers to cell phones results in a growing demand for web-based access to control system data. At the Oak Ridge National Laboratory Spallation Neutron Source (SNS) we have investigated different technical approaches to provide read access to data in the Experimental Physics and Industrial Control System (EPICS) for a wide variety of web client devices. The core web technology, HTTP, is less than ideal for online control system displays. Appropriate use of Ajax, especially the Long Poll paradigm, can alleviate fundamental HTTP limitations. The SNS Status web uses basic Ajax technology to generate generic displays for a wide audience. The Dashboard uses Long Poll and more client-side Java-Script to offer more customization and faster updates for users that need specialized displays. The Web OPI uses RAP for web access to any BOY display, offering utmost flexibility because users can create their own BOY displays in CSS. These three approaches complement each other. Users can access generic status displays with zero effort, invest time in creating their fully customized displays for the Web OPI, or use the Dashboard as an intermediate solution

    In this review, an odor sensing system and an olfactory display are introduced into people in pharmacy. An odor sensing system consists of an array of sensors with partially overlapping specificities and pattern recognition technique. One of examples of odor sensing systems is a halitosis sensor which quantifies the mixture composition of three volatile sulfide compounds. A halitosis sensor was realized using a preconcentrator to raise sensitivity and an electrochemical sensor array to suppress the influence of humidity. Partial least squares (PLS) method was used to quantify the mixture composition. The experiment reveals that the sufficient accuracy was obtained. Moreover, the olfactory display, which present scents to human noses, is explained. A multi-component olfactory display enables the presentation of a variety of smells. The two types of multi-component olfactory display are described. The first one uses many solenoid valves with high speed switching. The valve ON frequency determines the concentration of the corresponding odor component. The latter one consists of miniaturized liquid pumps and a surface acoustic wave (SAW) atomizer. It enables the wearable olfactory display without smell persistence. Finally, the application of the olfactory display is demonstrated. Virtual ice cream shop with scents was made as a content of interactive art. People can enjoy harmony among vision, audition and olfaction. In conclusion, both odor sensing system and olfactory display can contribute to the field of human health care.

    Two important human depth cues are accommodation and vergence. Normally, the eyes accommodate and converge or diverge in tandem; changes in viewing distance cause the eyes to simultaneously adjust both focus and orientation. However, ambiguity between accommodation and vergence cues is a well-known limitation in many stereoscopic display technologies. This limitation also arises in state-of-the-art full-flight simulator displays. In current full-flight simulators, the out-the-window (OTW) display (i.e., the front cockpit window display) employs a fixed collimated display technology which allows the pilot and copilot to perceive the OTW training scene without angular errors or distortions; however, accommodation and vergence cues are limited to fixed ranges (e.g., ~ 20 m). While this approach works well for long-range, the ambiguity of depth cues at shorter range hinders the pilot's ability to gauge distances in critical maneuvers such as vertical take-off and landing (VTOL). This is the first in a series of papers on a novel, variable-collimation display (VCD) technology that is being developed under NAVY SBIR Topic N121-041 funding. The proposed VCD will integrate with rotary-wing and vertical take-off and landing simulators and provide accurate accommodation and vergence cues for distances ranging from approximately 3 m outside the chin window to ~ 20 m. A display that offers dynamic accommodation and vergence could improve pilot safety and training, and impact other applications presently limited by lack of these depth cues.

    Display technologies are fundamental to the isolation of specific high-affinity binding proteins for diagnostic and therapeutic applications in cancer, neurodegenerative, and infectious diseases as well as autoimmune and inflammatory disorders. Applications extend into the broad field of antibody (Ab) engineering, synthetic enzymes, proteomics, and cell-free protein synthesis. Recently, in vitro display technologies have come to prominence due to the isolation of high-affinity human antibodies by phage display, the development of novel scaffolds for ribosome display, and the discovery of novel protein-protein interactions. In vitro display represents an emerging and innovative technology for the rapid isolation and evolution of high-affinity peptides and proteins. So far, only one clinical drug candidate produced by in vitro display technology has been approved by the FDA for use in humans, but several are in clinical or preclinical testing. This review highlights recent advances in various engineered biopharmaceutical products isolated by in vitro display with a focus on the commercial developments.

    A tactile display is programmable device whose controlled surface is intended to be investigated by human touch. It has a great number of potential applications in the field of virtual reality and elsewhere. In this research, a 5 × 5 tactile display array including electrorheological (ER) fluid has been developed and investigated. Force responses of the tactile display array have been measured while a probe was moved across the upper surface. The purpose of this was to simulate the action of touch performed by human finger. Experimental results show that the sensed surface information could be controlled effectively by adjusting the voltage activation pattern imposed on the tactels. The performance of the tactile display is durable and repeatable. The touch sensitivity of this ER fluid based tactile display array has also been investigated in this research. The results show that it is possible to sense the touching force normal to the display's surface by monitoring the change of current passing through the ER fluid. These encouraging results are helpful for constructing a new type of tactile display based on ER fluid which can act as both sensor and actuator at the same time.

  18. From Rail-Oriented to Automobile-Oriented Urban Development and Back. 100 Years of Paradigm Change and Transport Policy in Berlin

    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

  20. Displays of emotion and citizen support for Merkel and Gysi.

    Gabriel, Oscar W; Masch, Lena

    2017-01-01

    Emotional appeals have always been an important instrument in the mobilization of political support in modern societies. As found in several experimental studies from the United States, the emotions displayed by leading politicians in their televised public appearances have an impact on the political attitudes and behaviors of the public. Positive emotions such as joy or happiness, pride, and amusement elicit a more positive assessment of politicians, whereas showing negative emotions such as anger or outrage often diminishes the public's support. This transfer of emotions from sender to recipient has been described as "emotional contagion." However, under specific circumstances, emotions expressed by politicians can result in counter-empathic reactions among recipients. To examine the role of emotions between political leaders and the public in an institutional and cultural setting outside the United States, this article presents experimental findings on the impact of emotions expressed by two leading German politicians on the German public. The study used emotional displays by Chancellor Angela Merkel and former parliamentary leader of the Left Party, Gregor Gysi, observing how their assessments by the German public changed in response to these displays. Consistent with existing research, we discovered positive effects on the evaluation of both politicians when they displayed positive emotions. However, the impact of negative emotions is different for Merkel and Gysi and can be described as contagion in the former and counter-contagion in the latter case. Furthermore, we found that individual recognition of the expressed emotions modified the effect they had on the evaluation of some leadership characteristics.

  1. Transparent 3D display for augmented reality

    Lee, Byoungho; Hong, Jisoo

    2012-11-01

    Two types of transparent three-dimensional display systems applicable for the augmented reality are demonstrated. One of them is a head-mounted-display-type implementation which utilizes the principle of the system adopting the concave floating lens to the virtual mode integral imaging. Such configuration has an advantage in that the threedimensional image can be displayed at sufficiently far distance resolving the accommodation conflict with the real world scene. Incorporating the convex half mirror, which shows a partial transparency, instead of the concave floating lens, makes it possible to implement the transparent three-dimensional display system. The other type is the projection-type implementation, which is more appropriate for the general use than the head-mounted-display-type implementation. Its imaging principle is based on the well-known reflection-type integral imaging. We realize the feature of transparent display by imposing the partial transparency to the array of concave mirror which is used for the screen of reflection-type integral imaging. Two types of configurations, relying on incoherent and coherent light sources, are both possible. For the incoherent configuration, we introduce the concave half mirror array, whereas the coherent one adopts the holographic optical element which replicates the functionality of the lenslet array. Though the projection-type implementation is beneficial than the head-mounted-display in principle, the present status of the technical advance of the spatial light modulator still does not provide the satisfactory visual quality of the displayed three-dimensional image. Hence we expect that the head-mounted-display-type and projection-type implementations will come up in the market in sequence.

    We present a quantitative and qualitative analysis of interruptions of interaction with a public display game, and explore the use of a manual pause mode in this scenario. In previous public display installations we observed users frequently interrupting their interaction. To explore ways...... of supporting such behavior, we implemented a gesture controlled multiuser game with four pausing techniques. We evaluated them in a field study analyzing 704 users and found that our pausing techniques were eagerly explored, but rarely used with the intention to pause the game. Our study shows...... are not well suited for games on public displays. Instead, interruptions should be implicitly supported by the application design....

    For nearly a decade the University of North Carolina at Chapel Hill has been conducting research in the use of simple head-mounted displays in "real-world" applications. Such units provide the user with non-holographic true three-dimensional information, since the kinetic depth effect, stereoscopy, and other visual cues combine to immerse the user in a "virtual world" which behaves like the real world in some respects. UNC's head-mounted display was built inexpensively from commercially available off-the-shelf components. Tracking of the the user's head position and orientation is performed by a Polhemus Navigation Sciences' 3SPACE* tracker. The host computer uses the tracking information to generate updated images corresponding to the user's new left eye and right eye views. The images are broadcast to two liquid crystal television screens (220x320 pixels) mounted on a horizontal shelf at the user's forehead. The user views these color screens through half-silvered mirrors, enabling the computer-generated image to be superimposed upon the user's real physical environment. The head-mounted display has been incorporated into existing molecular modeling and architectural applications being developed at UNC. In molecular structure studies, chemists are presented with a room-sized molecule with which they can interact in a manner more intuitive than that provided by conventional two-dimensional displays and dial boxes. Walking around and through the large molecule may provide quicker understanding of its structure, and such problems as drug-enzyme docking may be approached with greater insight. In architecture, the head-mounted display enables clients to better appreciate three-dimensional designs, which may be misinterpreted in their conventional two-dimensional form by untrained eyes. The addition of a treadmill to the system provides additional kinesthetic input into the understanding of building size and scale.

    This report explores the visibility of an Electroluminescent (EL) display for automotive use. Displays for automobiles are exposed to the direct rays of the sun and forced to operate in wide temperature range. Therefore, luminous flux density by the lighting on EL display panel and operating environment temperature must be considered for the visibility evaluation. Sensory evaluation on the visibility and physical measurements such as contrast, chromaticity difference in accordance with the viewing angle change indicate that the visibility of the EL display for automobiles is advantageous over other displays. 6 refs., 11 figs., 1 tab.

    2018-05-01

    Based on modern theories of signal evolution and animal communication, the behavioral ecology view of facial displays (BECV) reconceives our 'facial expressions of emotion' as social tools that serve as lead signs to contingent action in social negotiation. BECV offers an externalist, functionalist view of facial displays that is not bound to Western conceptions about either expressions or emotions. It easily accommodates recent findings of diversity in facial displays, their public context-dependency, and the curious but common occurrence of solitary facial behavior. Finally, BECV restores continuity of human facial behavior research with modern functional accounts of non-human communication, and provides a non-mentalistic account of facial displays well-suited to new developments in artificial intelligence and social robotics.

    In these days, consumer's needs for image quality of mobile devices are increasing as smartphone is widely used. For example, colors may be perceived differently when displayed contents under different illuminants. Displayed white in incandescent lamp is perceived as bluish, while same content in LED light is perceived as yellowish. When changed in perceived white under illuminant environment, image quality would be degraded. Objective of the proposed white constancy method is restricted to maintain consistent output colors regardless of the illuminants utilized. Human visual experiments are performed to analyze viewers'perceptual constancy. Participants are asked to choose the displayed white in a variety of illuminants. Relationship between the illuminants and the selected colors with white are modeled by mapping function based on the results of human visual experiments. White constancy values for image control are determined on the predesigned functions. Experimental results indicate that propsed method yields better image quality by keeping the display white.

    Advanced image display systems for the fully digital diagnostic imaging departments of the future will be far more than simple replacements of the traditional film-viewing equipment. The new capabilities of very high resolution and highly dynamic displays offer a userfriendly and problem-oriented way of image interpretation. Advanced harware-, software- and human-machine interaction-concepts have been outlined. A scenario for a future way of handling and displaying images, reflecting a new image viewing paradigm in radiology is sketched which has been realized in an experimental image workstation model in the laboratory which, despite its technical complexity, offers a consistent strategy for fast and convenient interaction with image objects. The perspective of knowledge based techniques for workstation control software with object-oriented programming environments and user- and task-adaptive behavior leads to more advanced display properties and a new quality of userfriendliness. 2 refs.; 5 figs

    Compressive displays are an emerging technology exploring the co-design of new optical device configurations and compressive computation. Previously, research has shown how to improve the dynamic range of displays and facilitate high-quality light field or glasses-free 3D image synthesis. In this paper, we introduce a new multi-mode compressive display architecture that supports switching between 3D and high dynamic range (HDR) modes as well as a new super-resolution mode. The proposed hardware consists of readily-available components and is driven by a novel splitting algorithm that computes the pixel states from a target high-resolution image. In effect, the display pixels present a compressed representation of the target image that is perceived as a single, high resolution image. © 2014 Optical Society of America.

    Described, is the HinesLab '3DTV,' a 3-dimensional video display which provides true stereo 3-D images, without glasses. Multiple viewers can move in front of the display, seeing true stereo images with motion parallax. Applications include 3-D video arcade games, avionics, engineering workstations, scientific visualization, video phones, and 3-D television. The display is built around a single liquid crystal panel, on which multiple images are projected to a screen where they form the 3-D image. The relationships of objects are confirmed in three dimensional space as the viewer moves through the viewing positions. The HinesLab autostereoscopic technology is transparent to the user. The 3DTV display can be produced economically because it uses a single display panel and conventional optics. The primary advantage of this technique is its simplicity. CGI images are supplied to the monitor with a single video board. Three- dimensional television can be broadcast by a single unmodified television station (NTSC, PAL, SECAM, HDTV, etc.), and recorded and replayed in 3-D with a VCR. From 4 - 21 eye positions can be created, with a range of resolution and viewing angles, limited only by currently available liquid- crystal display technology.

    As the World Year of Physics (WYP) approaches, the AAPT WYP Committee would like to encourage everyone to consider ways to engage those around us in celebrating the science that makes us the proud geeks we are. The geek sentiment is my own, and does not necessarily reflect the views and opinions of the committee. This paper offers simple and inexpensive astronomy-related ideas for a bulletin-board-type display. The particular ideas presented below are hands-on classroom activities that I've adapted for display purposes. The display is static in that once constructed it does not require a personal facilitator, but each component invites interaction. At the end of the paper I revisit the idea of building a sundial1 as a highly visible and artistic way to engage students and communities in physics. The activities presented here are available for use when constructing your own display. In addition, these examples are meant to illustrate how instructional products might be modified for display purposes, and I encourage others to consider their favorite activities for an interactive display.

    2015-03-01

    The common architecture of multi-view autostereoscopic displays assigns a nominal viewing distance. The design affects the convergence of the visible rays at a nominal viewing distance where diamond shaped viewing zones are created. In contrast to this approach, the authors present a new design strategy departing from the geometric relations of common 3D display designs. They show that a beam emitted from a sub-pixel should be rendered with an individual camera direction determined by an algorithm. This algorithm also uses, besides the parameters of the display design, the desired viewing distance and the allowed increments of the camera angle. This enables very flexible designs of autostereoscopic displays. The main difference from the common multiview display is that its design approach enables a continued viewing zone without the usually diamond shaped sweet spots. The algorithm for controlling the rendering and the multiplexing is generic, as well as for integral and multiview design approaches using an image splitter raster. The paper introduces it for autostereoscopic displays with horizontal parallax.

    The Systems Engineering Simulator, located at the Lyndon B. Johnson Space Center in Houston, Texas, is tasked with providing a real-time simulator for developing displays and controls targeted for the Space Station Freedom. These displays and controls will exist inside an enclosed workstation located on the space station. The simulation is currently providing the engineering analysis environment for NASA and contractor personnel to design, prototype, and test alternatives for graphical presentation of data to an astronaut while he performs specified tasks. A highly desirable aspect of this environment is to have the capability to rapidly develop and bring on-line a number of different displays for use in determining the best utilization of graphics techniques in achieving maximum efficiency of the test subject fulfilling his task. The Systems Engineering Simulator now has available a tool which assists in the rapid development of displays for these graphic workstations. The Display Builder was developed in-house to provide an environment which allows easy construction and modification of displays within minutes of receiving requirements for specific tests.

    In recent years, transparent display is an emerging topic in display technologies. Apply in many fields just like mobile device, shopping or advertising window, and etc. Electrowetting Display (EWD) is one kind of potential transparent display technology advantages of high transmittance, fast response time, high contrast and rich color with pigment based oil system. In mass production process of Electrowetting Display, oil defects should be found by Automated Optical Inspection (AOI) detection system. It is useful in determination of panel defects for quality control. According to the research of our group, we proposed a mechanism of AOI detection system detecting the different kinds of oil defects. This mechanism can detect different kinds of oil defect caused by oil overflow or material deteriorated after oil coating or driving. We had experiment our mechanism with a 6-inch Electrowetting Display panel from ITRI, using an Epson V750 scanner with 1200 dpi resolution. Two AOI algorithms were developed, which were high speed method and high precision method. In high precision method, oil jumping or non-recovered can be detected successfully. This mechanism of AOI detection system can be used to evaluate the oil uniformity in EWD panel process. In the future, our AOI detection system can be used in quality control of panel manufacturing for mass production.

  8. Using crowdsourced data from citizen weather stations to analyse air temperature in 'local climate zones' in Berlin, Germany

    2017-04-01

    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

    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.

    2001-07-01

    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.

    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.

    2017-11-01

    The use of Display Screen Equipment (DSE) at enterprises allows one to increase the productivity and safety of production, minimize the number of personnel and leads to the simplification of the work of specialists, but on the other side, changes usual working conditions. If the personnel works with displays, visual fatigue develops more quickly which contributes to the emergence of nervous tension, stress and possible erroneous actions. Low interest of the lighting control system developers towards the rooms with displays is dictated by special requirements for coverage by sanitary and hygienic standards (limiting excess workplace illumination). We decided to create a combined lighting system which works considering daylight illumination and artificial light sources. The brightness adjustment of the LED lamps is carried out according to the DALI protocol, adjustment of the natural illumination by means of smart glasses. The technical requirements for a lighting control system, the structural-functional scheme and the algorithm for controlling the operation of the system have been developed. The elements of control units, sensors and actuators have been selected.

  17. Ultrarealistic imaging: the future of display holography

    Bjelkhagen, Hans I.; Brotherton-Ratcliffe, David

    2014-11-01

    Ultrarealistic imaging is the science of producing images that faithfully recreate the light field surrounding an object, such that the unaided eye of a human observer cannot distinguish the difference between the original and the image. Recent technology improvements are now set to transform the fields of both analog and digital display holography, permitting both techniques to operate in the ultrarealistic regime. In particular, ultrarealistic analog holograms have now heralded the serious use of holography in such areas as museum display and cultural heritage protection. These full-color holograms are characterized by a substantially lower noise and a greater spectral fidelity. New recording systems, based on recent diode-pumped solid-state and semiconductor lasers combined with recording materials and processing, have been behind these improvements. Progress in illumination technology, however, has also led to a major reduction in display noise and to a significant increase in the clear image depth and brightness of holograms. Recent progress in one-step direct-write digital holography (DWDH) is now also opening the way to the creation of a new type of ultrarealistic display: the high virtual volume display. This is a large format full-parallax DWDH reflection hologram having a fundamentally larger clear image depth.

    Recent advances in compact, air-cooled, diode-pumped solid- state visible microlasers have enabled the development of portable laser display systems. In addition to the added benefits of large color gamut, invariant color accuracy, image uniformity, high contrast, and large depth of focus inherent in the microlaser design, the reliability of these all-solid state red-green-blue (RGB) sources make them attractive for display applications. Compact, multi-watt laser modules have been demonstrated for use as a high brightness 'laser light engine' for replacing arc lamps in LCD/DMD type display configurations. Using this 'backlit' approach, a microlaser- based projector has been demonstrated, providing greater than 500 lumens at 1280 X 1024 resolution using reflective AMLCD light valves. Also being developed is an airborne tactical HMD system wherein the laser module is remotely coupled to a subtractive color LCD assembly through an optical fiber to provide a more than 24,000,000 (twenty-four million) cd/m2 luminance for illuminating the LCD assembly. This technology could be applied to a variety of cockpit displays providing sunlight readable illumination for both head-down and head-up backlit display configurations. The advantages of the microlaser technology will enable further applications in other military platforms such as command and control centers, simulators and HMDs. Longer term potential includes high end CAD workstations, entertainment systems, and electronic cinema.

    Houde, Jean-Christophe; Jodoin, Pierre-Marc; Desch"nes, François

    2012-03-01

    In this paper, we present a method to reconfigure 3D movies in order to minimize distortion when seen on a different display than the one it has been configured for. By their very nature, 3D broadcasts come with a stereoscopic pair to be seen by the left and right eyes. However, according to reasons that we ought to explain in the paper, the cameras used to shoot a movie are calibrated according to specific viewing parameters such as the screen size, the viewing distance and the eye separation. As a consequence, a 3D broadcast seen on a different display (say a home theater or a PC screen) than the one it has been configured for (say an IMAX R screen) will suffer from noticeable distortions. In this paper, we describe the relationship between the size of the 3D display, the position of the observer, and the intrinsic and extrinsic parameters of the cameras. With this information, we propose a method to reorganize the stereoscopic pair in order to minimize distortion when seen on an arbitrary display. In addition to the raw video pair, our method uses the viewing distance, a rough estimate of the 3D scene, and some basic information on the 3D display. An inpainting technique is used to fill disoccluded areas.

    Haptic feedback is strongly demanded for high-precision robot-assisted surgery and teleoperation. The haptic feedback consists of force and tactile feedback, however tactile feedback has been little studied and the size and weight of the system poses challenges for practical applications. In this paper we propose a sheet-type wearable electro-tactile display which provides tactile sensations to the user as the feedback at a low voltage and power consumption. The display possesses needle-shaped electrodes, which can penetrate through the high-impedance stratum corneum. We developed the fabrication process and, as the first step, we investigated the tactile sensation that can be created to the fingertip by the display. Rough and smooth surfaces were successfully presented to the user. Then, we characterized the tactile display when used on the forearm, in particular, with respect to the spatial resolution. These tactile displays can be used to inform the user of the surface property of the parts of interest, such as tumor tissues, and to guide him in the manipulation of surgery robots.

    We show how one can determine the various properties of light, from the modal content of laser beams to decoding the information stored in optical fields carrying orbital angular momentum, by performing a modal decomposition. Although the modal decomposition of light has been known for a long time, applied mostly to pattern recognition, we illustrate how this technique can be implemented with the use of liquid-crystal displays. We show experimentally how liquid crystal displays can be used to infer the intensity, phase, wavefront, Poynting vector, and orbital angular momentum density of unknown optical fields. This measurement technique makes use of a single spatial light modulator (liquid crystal display), a Fourier transforming lens and detector (CCD or photo-diode). Such a diagnostic tool is extremely relevant to the real-time analysis of solid-state and fibre laser systems as well as mode division multiplexing as an emerging technology in optical communication.

    1989-01-01

    An effort which investigated concepts for displaying dynamic system status and fault history (propagation) information to the flight crew is described. This investigation was performed by developing several candidate display formats and then conducting comprehension tests to determine those characteristics that made one format preferable to another for presenting this type of information. Twelve subjects participated. Flash tests, or limited time exposure tests, were used to determine the subjects' comprehension of the information presented in the display formats. It was concluded from the results of the comprehension tests that pictographs were more comprehensible than both block diagrams and text for presenting dynamic system status and fault history information, and that pictographs were preferred over both block diagrams and text. It was also concluded that the addition of this type of information in the cockpit would help the crew remain aware of the status of their aircraft.

    A high end visual display for High Energy Nuclear Physics (HENP) detectors is necessary because of the sheer size and complexity of the detector. For BNL this display will be of special interest because of STAR and ATLAS. To load, rotate, query, and debug simulation code with a modern detector simply takes too long even on a powerful work station. To visualize the HENP detectors with maximal performance we have developed software with the following characteristics. We develop a visual display of HENP detectors on BNL multiprocessor visualization server at multiple level of detail. We work with general and generic detector framework consistent with ROOT, GAUDI etc, to avoid conflicting with the many graphic development groups associated with specific detectors like STAR and ATLAS. We develop advanced OpenGL features such as transparency and polarized stereoscopy. We enable collaborative viewing of detector and events by directly running the analysis in BNL stereoscopic theatre. We construct enhanced interactiv...

    2013-01-01

    The experiments described here explored how pilots want available maneuver authority information transmitted and how this information affects pilots before and after an aircraft failure. The aircraft dynamic variables relative to flight performance were narrowed to energy management variables. A survey was conducted to determine what these variables should be. Survey results indicated that bank angle, vertical velocity, and airspeed were the preferred variables. Based on this, two displays were designed to inform the pilot of available maneuver envelope expressed as bank angle, vertical velocity, and airspeed. These displays were used in an experiment involving control surface failures. Results indicate the displayed limitations in bank angle, vertical velocity, and airspeed were helpful to the pilots during aircraft surface failures. However, the additional information did lead to a slight increase in workload, a small decrease in perceived aircraft flying qualities, and no effect on aircraft situation awareness.

    The Research and Development (R&D) project on “Theoretical and Methodological Approaches to Integrated System Validation of Control Rooms, 2014-2015”, in which the research activities described in this report are framed, has two main objectives: to develop the items for an usability methodology conceived as a part of the measurement framework for performance-based control room evaluation that the OECD Halden Reactor Project will test in the experiments planned for 2015; and the statistical analysis of the data generated in the experimental activities of the Halden Man-Machine Laboratory (HAMMLAB) facility, with previous usability questionnaires, in 2010 and 2011. In this report, the procedure designed to meet the first goal of the project is described, in particular, the process followed to identify the items related to information displays, one of the elements to be included in the usability questionnaire. Three phases are performed, in the first one, the approaches developed by the United States Nuclear Regulatory Commission, NRC, are reviewed and the models proposed by the nuclear energy industry and their technical support organizations, mainly, the United States Electric Power Research Institute, EPRI, are analyzed. In the remaining stages, general and specific guidelines for information displays, in particular, display pages, formats, elements and data quality and update rate recommendations are compared and criteria for the preliminary selection of the items that should be incorporated into the usability questionnaire are defined. This proposal will be reviewed and adapted by the Halden Reactor Project to the design of the specific experiments performed in HAMMLAB.

    The importance of the design of human machine interfaces (HMIs) for human performance and safety has long been recognized in process industries. In case of nuclear power plants (NPPs), HMIs have significant implications for the safety of the NPPs since poor implementation of HMIs can impair the operators' information searching ability which is considered as one of the important aspects of human behavior. To support and increase the efficiency of the operators' information searching behavior, advanced HMIs based on computer technology are provided. Operators in advanced main control room (MCR) acquire information through video display units (VDUs), and large display panel (LDP) required for the operation of NPPs. These computer-based displays contain a very large quantity of information and present them in a variety of formats than conventional MCR. For example, these displays contain more elements such as abbreviations, labels, icons, symbols, coding, and highlighting than conventional ones. As computer-based displays contain more information, complexity of the elements becomes greater due to less distinctiveness of each element. A greater understanding is emerging about the effectiveness of designs of computer-based displays, including how distinctively display elements should be designed. And according to Gestalt theory, people tend to group similar elements based on attributes such as shape, color or pattern based on the principle of similarity. Therefore, it is necessary to consider not only human operator's perception but the number of element consisting of computer-based display

    People who are blind or visually impaired face difficulties using a growing array of everyday appliances because they are equipped with inaccessible electronic displays. We report developments on our "Display Reader" smartphone app, which uses computer vision to help a user acquire a usable image of a display and have the contents read aloud, to address this problem. Drawing on feedback from past and new studies with visually impaired volunteer participants, as well as from blind accessibility experts, we have improved and simplified our user interface and have also added the ability to read seven-segment digit displays. Our system works fully automatically and in real time, and we compare it with general-purpose assistive apps such as Be My Eyes, which recruit remote sighted assistants (RSAs) to answer questions about video captured by the user. Our discussions and preliminary experiment highlight the advantages and disadvantages of fully automatic approaches compared with RSAs, and suggest possible hybrid approaches to investigate in the future.

    2016-01-01

    Full Text Available Three-dimensional vision has acquired great importance in the audiovisual industry in the past ten years. Despite this, the first generation of autostereoscopic displays failed to generate enough consumer excitement. Some reasons are little 3D content and performance issues. For this reason, an exponential increase in three-dimensional vision research has occurred in the last few years. In this review, a study of the historical impact of the most important technologies has been performed. This study is carried out in terms of research manuscripts per year. The results reveal that research on spatial multiplexing technique is increasing considerably and today is the most studied. For this reason, the state of the art of this technique is presented. The use of microlenses seems to be the most successful method to obtain autostereoscopic vision. When they are fabricated with liquid crystal materials, extended capabilities are produced. Among the numerous techniques for manufacturing liquid crystal microlenses, this review covers the most viable designs for its use in autostereoscopic displays. For this reason, some of the most important topologies and their relation with autostereoscopic displays are presented. Finally, the challenges in some recent applications, such as portable devices, and the future of three-dimensional displays based on liquid crystal microlenses are outlined.

    2014-08-01

    Clustering commodity displays into a Tiled Display Wall (TDW) provides a cost-effective way to create an extremely high resolution display, capable of approaching the image sizes now generated by modern astronomical instruments. Many research institutions have constructed TDWs on the basis that they will improve the scientific outcomes of astronomical imagery. We test this concept by presenting sample images to astronomers and non-astronomers using a standard desktop display (SDD) and a TDW. These samples include standard English words, wide field galaxy surveys and nebulae mosaics from the Hubble telescope. Our experiments show that TDWs provide a better environment than SDDs for searching for small targets in large images. They also show that astronomers tend to be better at searching images for targets than non-astronomers, both groups are generally better when employing physical navigation as opposed to virtual navigation, and that the combination of two non-astronomers using a TDW rivals the experience of a single astronomer. However, there is also a large distribution in aptitude amongst the participants and the nature of the content also plays a significant role in success.

    Most cartographers and map designers are familiar with the problem of congestion of symbols on maps and cartographic displays. Geographic objects are often clustered in some areas and at the same time the remaining map space is left virtually empty. One example of this problem is the representation of networks such as electric grids, transportation, or communication networks. The elements of the networks are typically clustered around highly populated areas while the rest of the map contains relatively few nodes, links, and other features. In this study we are investigating the applicability of several continuous geometric transformations to reduce the clutter on maps and cartographic displays. The techniques tested include map projections with customized parameters, perspective transformation of the map plane, fish-eye, and a diffusion-based algorithm for equalizing feature density. The map space is transformed so that a user can discern details in the areas with high density of the features while preserving the larger context and links between local and more general contexts. We use animation to provide the user with more visual clues and simplify comprehension of the transformed map. The study shows that the proposed techniques are useful for improving graphical efficiency of cartographic displays and produce visually appealing results. The choice of a specific decluttering method depends upon the purpose, geometric configuration of the portrayed objects, and display device resolution.

    Liquid crystal display panels were built using matrix configurations. With predeformed liquid crystal structures, steep electro-optic characteristics, and small on-off switching ratios, electrically controllable birefringence is obtainable. This allows the addressing of projection color matrix displays with up to 90 scanned lines in a two color representation and up to 40 lines in a four color representation at a rate of 50 frames per sec. The same holds for predeformed liquid crystals having the advantage of low operating voltages, such as commercially available CMOS IC's Matrix displays with 32 x 32 and 80 x 80 picture elements with the corresponding electronic addressing devices for projection images with controllable color were assembled. Using these twisted nematic (TN) liquid crystal displays, the possibility of color switching filters in a sequential color selection mode was investigated. An experimental setup consisting of a CRT with two color phosphor screen, a color switching filter with a TN cell, and on electronic addressing device for the synchronized switching of image signals and of the corresponding colors is described.

    Sarma, Kalluri R.

    Advances in the science and technology of hydrogenated amorphous silicon (a-Si:H, also referred to as a-Si) and the associated devices including thin-film transistors (TFT) during the past three decades have had a profound impact on the development and commercialization of major applications such as thin-film solar cells, digital image scanners and X-ray imagers and active matrix liquid crystal displays (AMLCDs). Particularly, during approximately the past 15 years, a-Si TFT-based flat panel AMLCDs have been a huge commercial success. a-Si TFT-LCD has enabled the note book PCs, and is now rapidly replacing the venerable CRT in the desktop monitor and home TV applications. a-Si TFT-LCD is now the dominant technology in use for applications ranging from small displays such as in mobile phones to large displays such as in home TV, as well-specialized applications such as industrial and avionics displays.

  3. Teleoperator performance with virtual window display

    The virtual window display is a hybrid of the head-coupled, helmet-mounted display and the fixed CRT mounted on a tabletop. Moving the CRTs from the operator''s head retains the benefits of motion parallax while providing higher quality color images, greater comfort and fewer restrictions on the operator''s view of the control site. A prototype virtual window display was constructed with direct mechanical linkage to servo camera movements to the operator''s head motions. This apparatus was used to compare remote performance with and without motion parallax, paired with either stereoscopic or monoscopic views. Mean stereoacuity and depth scaling responses for six observers of a Howard-Dolman apparatus showed improved performance when motion parallax accompanied monoscopic, but not stereoscopic view. Mean performance times for six observers retrieving objects from a wire maze show similar, though not significant, improvement when motion parallax accompanies monoscopic view. Observers report that manipulator requirements for hand steadiness reduce the opportunity to get depth information from head movements. The use of motion parallax information in a monoscopic virtual window display can improve teleoperator performance.

    The operant model of chronic pain posits that nonverbal pain behavior, such as facial expressions, is sensitive to reinforcement, but experimental evidence supporting this assumption is sparse. The aim of the present study was to investigate in a healthy population a) whether facial pain behavior can indeed be operantly conditioned using a discriminative reinforcement schedule to increase and decrease facial pain behavior and b) to what extent these changes affect pain experience indexed by self-ratings. In the experimental group (n = 29), the participants were reinforced every time that they showed pain-indicative facial behavior (up-conditioning) or a neutral expression (down-conditioning) in response to painful heat stimulation. Once facial pain behavior was successfully up- or down-conditioned, respectively (which occurred in 72% of participants), facial pain displays and self-report ratings were assessed. In addition, a control group (n = 11) was used that was yoked to the reinforcement plans of the experimental group. During the conditioning phases, reinforcement led to significant changes in facial pain behavior in the majority of the experimental group (p .136). Fine-grained analyses of facial muscle movements revealed a similar picture. Furthermore, the decline in facial pain displays (as observed during down-conditioning) strongly predicted changes in pain ratings (R(2) = 0.329). These results suggest that a) facial pain displays are sensitive to reinforcement and b) that changes in facial pain displays can affect self-report ratings.

    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

    Recent years have seen a fast technical development within the display area. Displays get ever higher pixel density and the pixels get smaller. Current displays have over 800 PPI and market forces will eventually drive for densities of 2000 PPI or higher. The transistor backplanes also get more complex. OLED displays require 4-7 transistors per pixel instead of the typical 1-2 transistors used for LCDs, and they are significantly more sensitive to errors. New large-area maskwriters have been developed for masks used in high volume production of screens for state-of-theart smartphones. Redesigned laser optics with higher NA and lower aberrations improve resolution and CD uniformity and reduce mura effects. The number of beams has been increased to maintain the throughput despite the higher writing resolution. OLED displays are highly sensitive to placement errors and registration in the writers has been improved. To verify the registration of produced masks a separate metrology system has been developed. The metrology system is self-calibrated to high accuracy. The calibration is repeatable across machines and sites using Z-correction. The repeatability of the coordinate system makes it possible to standardize the coordinate system across an entire supply chain or indeed across the entire industry. In-house metrology is a commercial necessity for high-end mask shop, but also the users of the masks, the panel makers, would benefit from having in-house metrology. It would act as the reference for their mask suppliers, give better predictive and post mortem diagnostic power for the panel process, and the metrology could be used to characterize and improve the entire production loop from data to panel.

    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
