    Leptospirosis is a bacterial zoonosis in which dogs can act as a reservoir for human infection. The annual vaccination of dogs can prevent leptospirosis caused by serovars included in the vaccine. To date, all available vaccines in Germany include only the serovars Icterohaemorrhagiae and Canicola, the most commonly found serovars prior to the introduction of the leptospirosis vaccines. Yet, the involvement of additional serovars in the clinical presentation of leptospirosis in dogs has been described. The objective of this sero-epidemiological study was to examine the different Leptospira serovars currently circulating in a population of dogs suspicious for leptospirosis from Berlin. In 329 dogs presenting at the Small Animal Clinic in Berlin, the predominant serogroup was Australis (24%), followed by Grippotyphosa (20%) and Pomona (9%). A total of 18% of the dogs were diagnosed with clinical leptospirosis; here the most prevalent serogroups were also Australis (28%), Grippotyphosa (18%), and Pomona (14%). The serovar prevalence data presented here confirm that a change of pattern of infecting Leptospira serovars in dogs has taken place in Berlin. This data corresponds to further sero-epidemiological studies from other regions in Germany. To ensure human and canine health, available vaccines should be adapted to include the most important circulating serovars.

  2. ["Shock" therapies in Nazi Germany. The example of Berlin psychiatry].

    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.

    2012-02-01

    This study aimed to determine whether >110 years of sewage application has led to recognizable changes in the metal chemistry of soils from former sewage farms, Berlin, Germany. Background concentrations of soils and element enrichment factors were used for the evaluation of possible perturbations of natural element abundances in sewage farm soils. Calculations verify that precious metals (Ag, Au) as well as P, C(org), and heavy metals (Cd, Cu, Ni, Pb, Sn, and Zn) are invariably enriched in sewage farm topsoils (0-0.1 m depth) compared to local and regional background soils. Long-term irrigation of soils with municipal wastewater has caused significant heavy metal contamination as well as a pronounced enrichment in precious metals. Leaching of metals including Ag into underlying aquifers may impact on the quality of drinking water supplies.

  5. The Berlin Poliklinik: psychoanalytic innovation in Weimar Germany.

    1999-01-01

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

    PubMed

    Cabello C, Felipe

    2013-04-01

    Georg Friedrich Nicolai (1874-1964) was a German physician and physiologist whose pacifism during the First World War led him in 1914 to cosign with W. J. Foerster, A. Einstein and O. Bueck a "Manifesto to the Europeans" against the entry of Germany into the war and the invasion of Belgium. As a result of this appeal and his strong pacifism, Nicolai lost his positions as cardiologist to the German royal family, professor at the University of Berlin and chief of laboratory at the Charite hospital also in Berlin, and was sent as a garrison physician in Graundenz, in today's Poland. There he began to write his book, The Biology of War. It managed to avoid censorship and was published in Leipzig in 1916. He was court-martialed in Danzig in 1916 but escaped to Denmark. Nicolai was reinstated to his faculty positions by the Weimar Republic after the war but was subsequently forced to emigrate from Germany to South America by the pressure of right wing student groups who accused him of being a deserter and a traitor. From 1922 to 1932 Nicolai lived in Argentina, and from 1932 until his death in 1964, in Chile. In this later country Nicolai was professor in the University of Chile and interacted with members of the Chilean intelligentsia, including the poets Vicente Huidobro, Gonzalo Rojas and Pablo Neruda. Through his friendship with Chilean psychiatrist Agustin Tellez, Nicolai influenced the development of phenomenological psychiatric school in Chile. The Chilean novelist Fernando Alegria compared him favorably with Robert J. Oppenheimer and Linus Pauling.

  8. Discipline building in Germany: women and genetics at the Berlin Institute for Heredity Research.

    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.

    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.

    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.

    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.

    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

    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.

    In orthopaedic medicine in Germany, Lorenz Heister, practicing in the eighteenth century, is considered one of the fathers of German surgery and is renowned for his books on management of hemorrhage, wounds, fractures, bandaging, instrumentation and surgery. After Heister, at the beginning of the nineteenth century, orthopaedic medicine in Germany developed uniformly. In a period when few doctors were interested in a separate discipline of orthopaedics, Germany led in this field. Heine devoted himself to the development of the new profession of orthopaedics, and in 1816, he opened the first orthopaedic institute on German soil in the former monastery of St. Stephen, which later became known as the Karolinen-Institut. Along with Heine and his family, the special development of orthopaedics in Berlin may be attributed to the work of Dieffenbach who, in 1832, became professor at the University of Berlin and in 1840 director of the Clinical Institute for Surgery at Charité Hospital.

    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.

    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 estimate the health

    Aim of this study was to evaluate the occurrence of Mycoplasma (M.) haemofelis, Candidatus Mycoplasma (C. M.) turicensis, C M. haemominutum, Bartonella spp. (B. henselae, B. clarridgeiae and B. quintana) and Anaplasma (A.) phagocytophilum in cats in Northeast Germany in relation to their living conditions (indoor/outdoor/ stray cat), and tick/flea exposure. 265 cats were included in the study (150 indoor, 99 outdoor access, 16 stray cats). A questionnaire provided the following data: derivation, housing environment, and previous flea/tick exposure. Serum antibody titers against A. phagocytophilum, B. henselae, and B. quintana were determined by an immunofluorescence test (IFT). PCR tests (EDTA blood) were used to test for A. phagocytophilum, M. haemofelis, C. M. turicensis, C. M. haemominutum, B. henselae and B. clarridgeiae. In 19 of 265 cats (7.2%) DNA of one or more Mycoplasma spp. was detected: C M. haemominutum (5.3%), M. haemofelis (1.5%) and C M. turicensis (1.1%); three of the cats were tested positive for the feline immunodeficiency virus. All cats were B. henselae and B. clarridgeiae PCR-negative in peripheral blood. However, 91 of 245 cats (37.1%) had antibody titers > 1:200 for B. henselae (Houston I, Marseille type) and 46 (18.8%) for B. quintana. Antibody titers > 1:64 against A. phagocytophilum were detected in 24 cats (9.1%); one cat (0.4%) was PCR-positive. Since infections with haemotropic Mycoplasma spp. and also with arthropodborne organisms (Bartonella spp., A. phagocytophilum) occur in cats from the area Berlin/Brandenburg (Germany) an appropriate arthropod-control is recommended. Further studies are needed to evaluate the relevance of these infectious agents for the individual cat.

    An ammonium contamination plume originating from sewage field management practices over several decades is affecting the water quality at the well fields of the Friedrichshagen waterworks in Berlin, Germany. Because hydraulic measures were unsuccessful due to the fixation of ammonium on the aquifer matrix by cation exchange, an in situ nitrification measure by injection of oxygen gas was chosen to protect the extraction wells. In order to assess the hydro chemical processes accompanying this in situ measure, reactive transport modelling was performed. The relevant processes are the dissolution of oxygen gas and the nitrification of ammonium which initiate secondary geochemical processes like sulphate release, acidification and hardening. The reactive transport modelling began with the deduction of a reaction network, followed by the mathematical formulation and incorporation of reactive terms into a reactive transport solver. Two model versions were set up: (1) a simplified large scale model to evaluate the long-term reaction zoning to be expected due to permanent oxygen gas injection, and (2) a verification of the monitored hydrochemistry during a first field test performed near the contamination source. The results of reactive transport modelling demonstrate that in situ injection of oxygen gas will be effective in reducing the ammonium load from the well fields, and that acidification processes near the production wells can be minimized. Finally, a line of gas injection wells extending over the whole width of the ammonium contamination plume will be constructed to protect the well fields from further ammonium load.

    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 m3000 m2000 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 microg/L of p-TSA and for o-TSA and BSA, a limit of 0.10 microg/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

    The goal of this study was to quantify the influence of the geological structure and geophysical parametrization of model units on the geothermal field as calculated by 3D numerical simulations of coupled fluid and heat transport for the subsurface of Berlin, Germany. The study area is located in the Northeast German Basin which is filled with several kilometers of sediments. This sedimentary infill includes the clastic sedimentary units Middle Buntsandstein and Sedimentary Rotliegend which are of particular interest for geothermal exploration. Previous studies conducted in the Northeast German Basin have already shown the geometries and properties of the geological units majorly control the distribution of subsurface temperatures. In this study we followed a two-step approach, where we first improved an existing structural model by integrating newly available 57 geological cross-sections, well data and deep seismics (down to ~4 km). Secondly, we performed a sensitivity analysis investigating the effects of varying physical fluid and rock properties on the subsurface temperature field. The results of this study show, that the structural configuration of model units exerts the highest influence on the geothermal field (up to ± 23 K at 1000 m below sea level). Here, the Rupelian clay aquitard, displaying a heterogeneous thickness distribution, locally characterized by hydrogeological windows (i.e. domains of no thickness) enabling intra-aquifer groundwater circulation has been identified as major controlling factor. The new structural configuration of this unit (more continuous, less numerous hydrogeological windows) also leads to a reduction of the influence of different boundary conditions and heat transport mechanisms considered. Additionally, the models results show that calculated temperatures highly depend on geophysical properties of model units whereas the hydraulic conductivity of the Cenozoic succession was identified as most dominant, leading to changes

    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.

    On July 9, 2014, Aeras and the Max Planck Institute for Infection Biology convened a workshop entitled "Whole Mycobacteria Cell Vaccines for Tuberculosis" at the Max Planck Institute for Infection Biology on the grounds of the Charité Hospital in Berlin, Germany, close to the laboratory where, in 1882, Robert Koch first identified Mycobacterium tuberculosis (Mtb) as the pathogen responsible for tuberculosis (TB). The purpose of the meeting was to discuss progress in the development of TB vaccines based on whole mycobacteria cells. Live whole cell TB vaccines discussed at this meeting were derived from Mtb itself, from Bacille Calmette-Guérin (BCG), the only licensed vaccine against TB, which was genetically modified to reduce pathogenicity and increase immunogenicity, or from commensal non-tuberculous mycobacteria. Inactivated whole cell TB and non-tuberculous mycobacterial vaccines, intended as immunotherapy or as safer immunization alternatives for HIV+ individuals, also were discussed. Workshop participants agreed that TB vaccine development is significantly hampered by imperfect animal models, unknown immune correlates of protection and the absence of a human challenge model. Although a more effective TB vaccine is needed to replace or enhance the limited effectiveness of BCG in all age groups, members of the workshop concurred that an effective vaccine would have the greatest impact on TB control when administered to adolescents and adults, and that use of whole mycobacteria cells as TB vaccine candidates merits greater support, particularly given the limited understanding of the specific Mtb antigens necessary to generate an immune response capable of preventing Mtb infection and/or disease.

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

    Research on the fate and transport of endocrine-disrupting compounds and other organic wastewater compounds released into the environment and their potential presence in drinking water is in its infancy. Studies conducted during the last decade in Lincoln, Nebraska, and Berlin, Germany, indicate that removal of less polar compounds probably can be obtained through bank filtration, ground-water enrichment, and additional drinking-water and wastewater treatment processes. Polar compounds, such as atrazine and some metabolites, occur in drinking water obtained from contaminated surface water or ground water, but at concentrations generally lower than those occurring in wastewater and surface water. The results of the studies also suggest that concentrations of nonpolar estrogenic compounds decrease during drinking-water pretreatment processes such as bank filtration and ground-water enrichment.

    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.

    The occurrence and distribution of six psychoactive compounds (primidone, phenobarbital, oxazepam, diazepam, meprobamate, and pyrithyldione) and a metabolite of primidone (phenylethylmalonamide) were investigated in wastewater treatment plant (WWTP) effluents, surface water, groundwater of a bank filtration site, raw and final drinking water, and in groundwater affected by former sewage irrigation. Primidone and its metabolite phenylethylmalonamide were found to be ubiquitous in environmental water samples in Berlin. Maximum concentrations of 0.87 and 0.42 μg/L, respectively, were encountered in WWTP effluents. Both compounds are apparently not removed when passaging through the different compartments of the water cycle and concentrations are only reduced by dilution. Phenobarbital was present at nearly every stage of the Berlin water cycle with the exception of raw and final drinking water. The highest concentrations of phenobarbital (up to 0.96 μg/L) were measured in groundwater influenced by former sewage irrigation. Oxazepam was only present in WWTP effluents and surface waters (up to 0.18 μg/L), while diazepam was not detected in any matrix. Due to their withdrawal from the German market years ago, the pharmaceuticals meprobamate and pyrithyldione were only found in sewage farm groundwater (up to 0.50 and 0.04 μg/L, respectively) and, in case of meprobamate, also in decade old bank filtrate (0.03 μg/L). Our results indicate a high persistence of some of the investigated compounds in the aquatic system. As a consequence, these pollutants may potentially reach drinking water resources via bank filtration if present in WWTP effluents and/or surface waters in partly closed water cycles such as Berlin's.

    PM 10 and PM 1 aerosol samples were collected between February and October, 2010 at three sites in Berlin that were characterized by different vegetation influences. The aim of the study was to determine the spatial and seasonal variations of several, mainly biogenic secondary and primary tracers in an urban area. Selected tracers including isoprene and α-pinene markers, fatty acids and levoglucosan were detected with GC-MS. The highest median concentrations, up to 45.1 ng m -3, were found for the combustion product levoglucosan. The concentration range of the secondary compounds was 0.3 ng m -3 for the isoprene markers 2-methyltetrols up to 35.7 ng m -3 for malic acid. The occurrence of these compounds was mainly affected by the seasons, which could be described by three patterns. Whereas secondary compounds were mainly characterized by significantly higher concentrations during the warmer months, levoglucosan showed significantly higher concentrations during the colder months. No significant concentration differences between the two periods were rather observed for the primary compounds but also for the α-pinene degradation product pinonic acid. The secondary compounds and levoglucosan could be associated with the fine mode (particles with an aerodynamic diameter (AD) < 1 μm), while primary compounds are rather associated with the coarse mode (AD > 1 μm). Spatial variations were emphasized with a tendency toward higher concentrations for most compounds at sites that were influenced by vegetation, especially evident for the PM 10 fraction. Besides concentration differences, spatial variations could also be described by differences in seasonal behavior and the size distribution, indicating major complexity in the composition of biogenic PM within the city of Berlin.

    This article reports on a field modelling study to investigate the processes controlling the plume evolution of para-toluenesulfonamide (p-TSA) in anoxic groundwater in Berlin, Germany. The organic contaminant p-TSA originates from the industrial production process of plasticisers, pesticides, antiseptics and drugs and is of general environmental concern for urban water management. Previous laboratory studies revealed that p-TSA is degradable under oxic conditions, whereas it appears to behave conservatively in the absence of oxygen (O2). p-TSA is ubiquitous in the aquatic environment of Berlin and present in high concentrations (up to 38 μg L(-1)) in an anoxic aquifer downgradient of a former sewage farm, where groundwater is partly used for drinking water production. To obtain refined knowledge of p-TSA transport and degradation in an aquifer at field scale, measurements of p-TSA were carried out at 11 locations (at different depths) between 2005 and 2010. Comparison of chloride (Cl(-)) and p-TSA field data showed that p-TSA has been retarded in the same manner as Cl(-). To verify the transport behaviour under field conditions, a two-dimensional transport model was setup, applying the dual-domain mass transfer approach in the model sector corresponding to an area of high aquifer heterogeneity. The distribution of Cl(-) and p-TSA concentrations from the site was reproduced well, confirming that both compounds behave conservatively and are subjected to retardation due to back diffusion from water stagnant zones. Predictive simulations showed that without any remediation measures, the groundwater quality near the drinking water well galleries will be affected by high p-TSA loads for about a hundred years.

    Humans spend most of their time in confined spaces and are hence primarily exposed to the direct influence of indoor climate. The Universal Thermal Climate Index (UTCI) was obtained in 31 rooms (eight buildings) in Berlin, Germany, during summer 2013 and 2014. The indoor UTCI was determined from measurements of both air temperature and relative humidity and from data of mean radiant temperature and air velocity, which were either measured or modeled. The associated outdoor UTCI was obtained through facade measurements of air temperature and relative humidity, simulation of mean radiant temperature, and wind data from a central weather station. The results show that all rooms experienced heat stress according to UTCI levels, especially during heat waves. Indoor UTCI varied up to 6.6 K within the city and up to 7 K within building. Heat stress either during day or at night occurred on 35 % of all days. By comparing the day and night thermal loads, we identified maximum values above the 32 °C threshold for strong heat stress during the nighttime. Outdoor UTCI based on facade measurements provided no better explanation of indoor UTCI variability than the central weather station. In contrast, we found a stronger relationship of outdoor air temperature and indoor air temperature. Building characteristics, such as the floor level or window area, influenced indoor heat stress ambiguously. We conclude that indoor heat stress is a major hazard, and more effort toward understanding the causes and creating effective countermeasures is needed.

    Currently, 52 % of the world's population resides in urban areas and as a consequence, approximately 70 % of fossil fuel emissions of CO2 arise from cities. This fact, in combination with large uncertainties associated with quantifying urban emissions due to lack of appropriate measurements, makes it crucial to obtain new measurements useful to identify and quantify urban emissions. This is required, for example, for the assessment of emission mitigation strategies and their effectiveness. Here, we investigate the potential of a satellite mission like Carbon Monitoring Satellite (CarbonSat) which was proposed to the European Space Agency (ESA) to retrieve the city emissions globally, taking into account a realistic description of the expected retrieval errors, the spatiotemporal distribution of CO2 fluxes, and atmospheric transport. To achieve this, we use (i) a high-resolution modelling framework consisting of the Weather Research Forecasting model with a greenhouse gas module (WRF-GHG), which is used to simulate the atmospheric observations of column-averaged CO2 dry air mole fractions (XCO2), and (ii) a Bayesian inversion method to derive anthropogenic CO2 emissions and their errors from the CarbonSat XCO2 observations. We focus our analysis on Berlin, Germany using CarbonSat's cloud-free overpasses for 1 reference year. The dense (wide swath) CarbonSat simulated observations with high spatial resolution (approximately 2 km × 2 km) permits one to map the city CO2 emission plume with a peak enhancement of typically 0.8-1.35 ppm relative to the background. By performing a Bayesian inversion, it is shown that the random error (RE) of the retrieved Berlin CO2 emission for a single overpass is typically less than 8-10 Mt CO2 yr-1 (about 15-20 % of the total city emission). The range of systematic errors (SEs) of the retrieved fluxes due to various sources of error (measurement, modelling, and inventories) is also quantified. Depending on the assumptions made, the SE

    Berlin has always been a literary space of extremely diverse political and cultural projections. This essay investigates why after the unification of East and West Berlin the city has been imagined as a play zone of sexual self-fulfilment by authors such as Inka Parei, Tanja Dückers, Kathrin Röggla, Judith Hermann and Julia Franck. Have such erotic adventures replaced political vision in our post-utopian decade? What is the purpose of the laboured allegorisation of the fall of the wall in Durs Grünbein's essays or in the novels of Katja Lange-Müller and Thomas Hettche? The sexification of historical and political processes recalls similar stereotypes in the East German literature of the 1980s: the metropolis as a whore in works by Heiner Müller or Wolf Biermann, but also by younger authors of the independent literary scene in Berlin like Uwe Kolbe or Frank-Wolf Matthies.

    Background Studies in the literature have indicated that the timing of seasonal influenza epidemic varies across latitude, suggesting the involvement of meteorological and environmental conditions in the transmission of influenza. In this study, we investigated the link between meteorological parameters and influenza activity in 9 sub-national areas with temperate and subtropical climates: Berlin (Germany), Ljubljana (Slovenia), Castile and León (Spain) and all 6 districts in Israel. Methods We estimated weekly influenza-associated influenza-like-illness (ILI) or Acute Respiratory Infection (ARI) incidence to represent influenza activity using data from each country’s sentinel surveillance during 2000–2011 (Spain) and 2006–2011 (all others). Meteorological data was obtained from ground stations, satellite and assimilated data. Two generalized additive models (GAM) were developed, with one using specific humidity as a covariate and another using minimum temperature. Precipitation and solar radiation were included as additional covariates in both models. The models were adjusted for previous weeks’ influenza activity, and were trained separately for each study location. Results Influenza activity was inversely associated (p<0.05) with specific humidity in all locations. Minimum temperature was inversely associated with influenza in all 3 temperate locations, but not in all subtropical locations. Inverse associations between influenza and solar radiation were found in most locations. Associations with precipitation were location-dependent and inconclusive. We used the models to estimate influenza activity a week ahead for the 2010/2011 period which was not used in training the models. With exception of Ljubljana and Israel’s Haifa District, the models could closely follow the observed data especially during the start and the end of epidemic period. In these locations, correlation coefficients between the observed and estimated ranged between 0.55 to 0.91and

    Objective The frequency of caesarean section delivery varies between countries and social groups. Among other factors, it is determined by the quality of obstetrics care. Rates of elective (planned) and emergency (in-labor) caesareans may also vary between immigrants (first generation), their offspring (second- and third-generation women), and non-immigrants because of access and language barriers. Other important points to be considered are whether caesarean section indications and the neonatal outcomes differ in babies delivered by caesarean between immigrants, their offspring, and non-immigrants. Methods A standardized interview on admission to delivery wards at three Berlin obstetric hospitals was performed in a 12-month period in 2011/2012. Questions on socio-demographic and care aspects and on migration (immigrated herself vs. second- and third-generation women vs. non-immigrant) and acculturation status were included. Data was linked with information from the expectant mothers’ antenatal records and with perinatal data routinely documented in the hospital. Regression modeling was used to adjust for age, parity and socio-economic status. Results The caesarean section rates for immigrants, second- and third-generation women, and non-immigrant women were similar. Neither indications for caesarean section delivery nor neonatal outcomes showed statistically significant differences. The only difference found was a somewhat higher rate of crash caesarean sections per 100 births among first generation immigrants compared to non-immigrants. Conclusion Unlike earlier German studies and current studies from other European countries, this study did not find an increased rate of caesarean sections among immigrants, as well as second- and third-generation women, with the possible exception of a small high-risk group. This indicates an equally high quality of perinatal care for women with and without a migration history. PMID:25985437

    An international symposium on the impact of environmental hazards, chemicals and drugs on the developing immune system of children was held in Berlin (Germany) organized by the BgVV. Epidemiological evidence indicates that an immature immune system challenged early in life by bacterial antigens may prevent, to some extent, allergic reactions including asthma bronchiale triggered by environmental pollutants. However, the prevalence for infectious disease is increased in childhood, especially when exposure to contaminants takes place in the period of pregnancy and breast-feeding. The effects of chlorinated biphenyls, dioxin, endotoxins, hexachlorobenzene, and direct and indirect in utero tobacco smoke exposure are examples. All participants recommend comparative and follow-up epidemiological studies and clinical examination of infants and children at risk during upbringing. There is ample evidence from experimental studies that indicates adverse effects on the developing immune system after in utero and postnatal exposure to chemicals and drugs. The adverse reactions of aciclovir, benzodiazepines, hexachlorobenzene, organotins (di-n-octyltin dichloride, tributyltin oxide), pesticides (methoxychlor, heptachlor) and polyhalogenated aromatic hydrocarbons (2,3,7,8-tetrachlorodibenzo-p-dioxin) are presented and reviewed. To determine the predictive value of test data in risk assessment for neonates and children, development, differentiation and maturation of the immune system in humans and laboratory rodents is compared in their pre- and postnatal stages. Considering some differences in immunocompetence at birth and after lactation, and differences in the time frame for maturation of the immune system, reaction types are thought to be common, comparable and similar in human childhood and early adolescence and the postnatal lifetime of laboratory rodents. The participants of the symposium felt strongly that regulatory steps urgently need to be initiated to incorporate some

    The fall of the Berlin wall caused a sudden increase in migration from East-Germany to West-Berlin. In our sample we compared 155 Berlin elementary school children to 17 children from East-Germany now living in Berlin and 25 immigrant children most oft them coming from Turkey and Poland. Although many authors expected short-term disorders of adaptation, we found a constancy of psychiatric diagnosis in the migration group. We noticed important differences particularly in the new psychosocial situation of the former East German mothers, with many single-mother-families, where the mothers now were often unemployed.

    After the fall of the Berlin Wall in November 1989, there was an immediate need for collaboration between rheumatologists from East- and West-Berlin from the very beginning, which could be taken as an example for the rest of Germany. This was achieved through different activities in patient care and research. The "Regionales Rheumazentrum Berlin" which was started at about that time played a special role in making this enterprise a success.

  17. Physics in Berlin I: The Historical City Center

    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

    Long-term mechanical circulatory support is a life-saving technology while briding to heart transplantation. It increases the quality of life and preserves end-organ function for patients with advanced heart failure. The number of patients with advanced heart failure scheduled for heart transplantation before comorbidities escalate is on the rise. However, the device function is complicated by the bleeding-thrombosis and infection paradigm, hence the interest in understanding device thrombosis and infection. We describe a 27-year-old man with idiopathic cardiomyopathy, advanced end-organ failure, and severe infection, who was bridged to heart transplantation after 8 months on the Berlin Heart EXCOR (Berlin Heart AG, Berlin, Germany) biventricular support. The patient was discharged from the hospital in the third postoperative week after the recovery of his end-organ functions. At 29 months’ post-transplantation follow-up, his last cardiac biopsy was grade 0, his ejection fraction was 60%, and he was enjoying a good quality of life. PMID:26985209

  19. The Berlin Emissivity Database

    NASA Astrophysics Data System (ADS)

    Helbert, Jorn

    Remote sensing infrared spectroscopy is the principal field of investigation for planetary surfaces composition. Past, present and future missions to the solar system bodies include in their payload instruments measuring the emerging radiation in the infrared range. TES on Mars Global Surveyor and THEMIS on Mars Odyssey have in many ways changed our views of Mars. The PFS instrument on the ESA Mars Express mission has collected spectra since the beginning of 2004. In spring 2006 the VIRTIS experiment started its operation on the ESA Venus Express mission, allowing for the first time to map the surface of Venus using the 1 µm emission from the surface. The MERTIS spectrometer is included in the payload of the ESA BepiColombo mission to Mercury, scheduled for 2013. For the interpretation of the measured data an emissivity spectral library of planetary analogue materials is needed. The Berlin Emissivity Database (BED) presented here is focused on relatively fine-grained size separates, providing a realistic basis for interpretation of thermal emission spectra of planetary regoliths. The BED is therefore complimentary to existing thermal emission libraries, like the ASU library for example. The BED contains currently entries for plagioclase and potassium feldspars, low Ca and high Ca pyroxenes, olivine, elemental sulphur, common martian analogues (JSC Mars-1, Salten Skov, palagonites, montmorillonite) and a lunar highland soil sample measured in the wavelength range from 3 to 50 µm as a function of particle size. For each sample, the spectra of four well defined particle size separates (¡25 µm , 25-63 µm, 63-125 µm, 125-250 µm) are measured with a 4 cm-1 spectral resolution. These size separates have been selected as typical representations for most of the planetary surfaces. Following an ongoing upgrade of the Planetary Emmissivity Laboratory (PEL) at DLR in Berlin measurements can be obtained at temperatures up to 500° C - realistic for the dayside conditions

  1. A vast medieval dam-lake cascade in northern central Europe: review and new data on late Holocene water-level dynamics of the Havel River, Berlin-Brandenburg area (Germany)

    An interdisciplinary study was carried out in order to trace the human transformation of the medium-scale Havel River in northeastern central Europe during the last c. 2000 years. This research was driven by the hypothesis that the present-day riverscape is widely a legacy of medieval and modern human transformation of the drainage system initiated essentially by damming for the operation of water mills. Recent opportunities to investigate the extent of this human impact arose during the course of archaeological rescue excavations and palaeoecologic studies, which significantly enhanced the amount of respective high-quality data. Along the middle course of the Havel, sedimentary sequences were analysed in order to explore the potential for reconstructing regional water-level dynamics. The river, draining the Berlin metropolitan area, forms a chain of dammed lakes and meandering river sections which were strongly modified by hydraulic engineering in the past. We have not only recorded new sections but also re-evaluated older ones, forming a total of sixteen sedimentary sequences along the river. Chronological control is provided by a multitude of palynological, dendrochronological, archaeological, and radiocarbon data. The sections upriver from the Brandenburg/H. and Spandau weirs, representing sites with historic water mills, reveal substantial water-level changes during the late Holocene. Generally, lower water levels before and higher levels parallel to the medieval German colonisation of that area (c. 1180/1250 AD) can be inferred. This water-level increase, which is attributed to be caused by medieval mill stowage, took place rapidly and amounted to a relative height of c. 1.5 m. It has caused the widening of river sections and the enlargement of existing lakes or its secondary formation when already aggraded, and thus a flooding of large portions of land. The rising water level has even influenced the settlement topography to a large degree. Several medieval

  2. [From traditional to modern hospital--from Paris to Berlin].

    PubMed

    Murken, Axel Hinrich

    Discussions about the modernisation and reform of the Hôtel Dieu in Paris concerning the catastrophic fire of 1772 there were followed very closely in Prussia and other German countries, though for a long time this had only slight consequences for modernising developments in the hospitals of Berlin or other administrative capitals of Germany. In contrast to this, the Hôpital Lariboisière was praised as a model example in Germany soon after its completion in 1854 after the pre-revolutionary Parisian plans, was imitated in Berlin twenty years later. It must be added that in Prussia great importance was attached to stricter requirements for hygiene and ventilation than in Paris. This was clearly demonstrated barely in the construction of the pavilionhospital in Berlin-Friedrichshain (1868-1874) with an extremely decentralized layout. It was not until two generations later with the completion of the municipal hospital Westend in Charlottenburg (1904-1907), a suburb of Berlin, that a slightly modified "Lariboisière" in the Wilheminian brick Baroque style was built. Similarily the acceptance of high-rise construction was, compared with Paris, considerably delayed on the German hospital scene. Whereas in the USA and France plans had been made for high-rise hospitals from the 1920s on and realized by 1935, as with the Hôpital Beaujon in Paris (1932-1935), there were fundamental reservations about them in Germany. As a result, this conception of the structure, with an effective concentration of inpatient care in towers together with separate low-rise buildings for functions such as treatment and diagnosis, only gradually gained acceptance in Germany at the end of the 1960s. On the other hand, German architects such as Hermann Distel (1875-1946) or Ernst Kopp (1890-1962), had already, indeed before the Second World War, promoted the high-rise type for inpatient care on theoretical grounds. In addition, two hospitals providing medical care within in Berlin, Martin

    In 2007, 2.7 million vertebrates were used for animal experiments and other scientific purposes in Germany alone. Since 1998 there has been an increase in the number of animals used for research purposes, which is partly attributable to the growing use of transgenic animals. These animals are, for instance, used as in vivo models to mimic human diseases like diabetes, cancer or Alzheimer's disease. Here, transgenic model organisms serve as valuable tools, being instrumental in facilitating the analysis of the molecular mechanisms underlying human diseases, and might contribute to the development of novel therapeutic approaches. Due to variable and, sometimes low, efficiency (depending on the species used), however, the generation of such animals often requires a large number of embryo donors and recipients. The experts evaluated methods that could possibly be utilised to reduce, refine or even replace experiments with transgenic vertebrates in the mid-term future. Among the promising alternative model organisms available at the moment are the fruit fly Drosophila melanogaster and the roundworm Caenorhabditis elegans. Specific cell culture experiments or three-dimensional (3D) tissue models also offer valuable opportunities to replace experiments with transgenic animals or reduce the number of laboratory animals required by assisting in decision-making processes. Furthermore, at the workshop an in vitro technique was presented which permits the production of complete human antibodies without using genetically modified ("humanised") animals. Up to now, genetically modified mice are widely used for this purpose. Improved breeding protocols, enhanced efficiency of mutagenesis as well as training of laboratory personnel and animal keepers can also help to reduce the numbers of laboratory animals. Well-trained staff in particular can help to minimise the pain, suffering and discomfort of animals and, at the same time, improve the quality of data obtained from animal

    The climate change in the region Berlin-Brandenburg is compared with the globally observed climate change. A temperature record extending for more than 300 years, including the notes by Gottfried Kirch, and a precipitation record longer than 100 years indicate that the climate change can be seen in the climate record of Berlin-Brandenburg as well, where the temperature is currently rising with 0.16° C per decade. The total number of frost days has declined by almost 17 days during the recent century; the number of summer days has increased by about 12 days during the same time. The annual mean precipitation has hardly changed (less than 0.2%) during the recent century. However, in summer the rain has decreased by about 4% and in winter increased by 3%. Model projections indicate that the warming will continue so that Berlin-Brandenburg will experience a temperature rise of about 3 - 3.5° C by the end of this century for the IPCC scenario A1B. For the same scenario the precipitation will increase in winter by 10 - 20% and decrease in summer by 10 - 30%: The seasonal precipitation changes compensate each other resulting in an almost unchanged annual mean.

    1996-07-01

    In this study of how to change people's conceptions of certain facts (i.e., the position of the Berlin Wall), a surprising psychological phenomenon was discovered. In the trial test, instead of designing a wall to enclose West Berlin, most people described and drew a short and straight wall that divided the city from north to south. Two methods were created, based on two general information-processing components involved in problem solving, to study how people might repair their misconceptions by themselves. The do-it-yourself method consisted of providing people with the task of thinking about how to build the wall and then drawing it, instead of just asking them to draw it. The distance-to-goal evaluation method consisted of asking the participants how the wall they had drawn would actually prevent passage from East Germany to West Berlin. The results showed that both methods had important effects in repairing misconceptions, but improvement in performance with the distance-to-goal method was less significant for those participants who were first provided the task of thinking about how to build the wall. These findings are consistent with the hypothesis that awareness of functional properties plays an important role in structuring and restructuring mental constructs.

    The Mississippi Valley-type (MVT) Zn-Pb-Ag deposit in the Wiesloch area, Southwest Germany, is controlled by graben-related faults of the Upper Rhinegraben. Mineralization occurs as vein fillings and irregular replacement ore bodies consisting of sphalerite, banded sphalerite, galena, pyrite, sulfosalts (jordanite and geocronite), barite, and calcite in the Middle Triassic carbonate host rock. Combining paragenetic information, fluid inclusion investigations, stable isotope and mineral chemistry with thermodynamic modeling, we have derived a model for the formation of the Wiesloch deposit. This model involves fluid mixing between ascending hot brines (originating in the crystalline basement) with sedimentary formation waters. The ascending brines originally had a near-neutral pH (around 6) and intermediate oxidation state, reflecting equilibrium with granites and gneisses in the basement. During fluid ascent and cooling, the pH of the brine shifted towards more acidic (around 4) and the oxidation state increased to conditions above the hematite-magnetite buffer. These chemical characteristics contrast strongly with those of the pore and fracture fluid residing in the limestone aquifer, which had a pH between 8 and 9 in equilibrium with calcite and was rather reduced due to the presence of organic matter in the limestone. Mixing between these two fluids resulted in a strong decrease in the solubility of silver-bearing sphalerite and galena, and calcite. Besides Wiesloch, several Pb-Zn deposits are known along the Upper Rhinegraben, including hydrothermal vein-type deposits like Badenweiler and the Michael mine near Lahr. They all share the same fluid origin and formation process and only differ in details of their host rock and fluid cooling paths. The mechanism of fluid mixing also seems to be responsible for the formation of other MVT deposits in Europe (e.g., Reocin, Northern Spain; Treves, Southern France; and Cracow-Silesia, Poland), which show notable

At postoperative day 296, a significant reduction of membrane movement was observed. The device was explanted and tested on a hydronumerical circulation simulator. Findings suggested that the integrity of the multilayered membrane had been compromised. This was confirmed by a computed tomography scan of the device. The computed tomography evidenced a detachment of the 3-layered membrane, with a thinner, convex layer on the side of the air chamber and an opposite convexity of the remaining membranes. These showed an additional air space within the layers.

    Remote-sensing infrared spectroscopy is the principal field of investigation for planetary surfaces composition. Past, present and future missions to the solar system bodies include in their payload, instruments measuring the emerging radiation in the infrared range. Apart from measuring the reflected radiance, more and more spacecrafts are equipped with instruments measuring directly the emitted radiation from the planetary surface. The emitted radiation is not only a function of the composition of the material but also of its texture and especially the grain size distribution. For the interpretation of the measured data an emissivity spectral library of planetary analogue materials in grain size fractions appropriate for planetary surfaces is needed. The Berlin emissivity database (BED) presented here is focused on relatively fine-grained size separates, providing thereby a realistic basis for the interpretation of thermal emission spectra of planetary regoliths. The BED is therefore complimentary to existing thermal emission libraries, like the ASU library for example. BED currently contains emissivity spectra of plagioclase and potassium feldspars, low Ca and high Ca pyroxenes, olivine, elemental sulfur, Martian analogue minerals and volcanic soils, and a lunar highland soil sample measured in the wavelength range from 7 to 22 μm as a function of particle size. For each sample we measured the spectra of four particle size separates ranging from <25 to 250 μm. The device we used is built at DLR (Berlin) and is coupled to a Fourier-transform infrared spectrometer Bruker IFS 88 purged with dry air and equipped with a nitrogen-cooled MCT detector. All spectra were acquired with a spectral resolution of 4 cm -1. We are currently working on upgrading our emissivity facility. A new spectrometer (Bruker VERTEX 80 V) and new detectors will allow us to measure the emissivity of samples in the wavelength range from 1 to 50 μm in a vacuum environment. This will be

    2010-03-01

    Following the collapse of socialism, fluctuations in cardiac mortality rates in East Germany and a West-to-East cardiac health gradient became topics of interest. Researchers suggested possible causes for these phenomena, including stress from postsocialism. I proposed that a cultural investigation of heart disease comorbid with depression could inform our understanding of the potential health effects of the postsocialist transition. I conducted ethnographic and survey research. In the study described here, I administered a depression scale (CES-D) and an ethnographically derived measure of cultural stress (Good Life Survey) to over 200 East and West Berliners with cardiovascular disease. Comparison of the groups' depression means revealed no difference. However, correlation of the Good Life Survey and the CES-D revealed unique profiles of cultural variables associated with depression in the two groups, suggesting that culture shapes depression and cardiac risk. I discuss the value of cultural studies to comorbidity research.

The goal of this compact Energy recovery linac (ERL) is to develop the accelerator physics and technology required to generate and accelerate a 100-mA, 1-mm mrad emittance electron beam. The BERLinPro know-how can then be transferred to various ERL-based applications. All accelerating RF cavities including the electron source are based on superconducting technology operated at 1.8 K. A Linde L700 helium liquefier is supplying 4.5 K helium. The subatmospheric pressure of 16 mbar of the helium bath of the cavities will be achieved by pumping with a set of cold compressors and warm vacuum pumps. While the L700 is already in operating, the 1.8 K system and the helium transfer system are in design phase.

  3. The acceleration of the masculine in early-twentieth-century Berlin.

    Prickett, David James

    2012-01-01

    In early-twentieth-century Berlin, agents of speed and industrialisation, such as the railway, contributed to the seemingly unbridled velocity of urban life. Doctors and cultural critics took an ambivalent stance toward the impact of speed and technology on the human body. Critics argued that these factors, in conjunction with sexual excess and prostitution, accelerated the sexual maturation of young men, thereby endangering ‘healthy’ male sexuality. This comparison of Hans Ostwald's socio-literary study Dunkle Winkel in Berlin (1904) with Georg Buschan's sexual education primer Vom Jüngling zum Mann (1911) queries the extent to which speed shaped the understanding of ‘the masculine’ in pre-World-War-I Germany. The essay thus examines Ostwald's and Buschan's arguments and postulates that speed in the city (Berlin) can be seen as a feminised, sexualised force that determined sex in the city. According to this reading, the homosexual urban dandy resisted the accelerated modernist urban tempo, whereas the heterosexual man and hegemonic, heteronormative masculinity yielded to speed. ‘“Das Verhältnis”’ became a fleeting, momentary alternative to stable marital relationships, which in turn contributed to the general ‘crisis’ of – and in– masculinity in early-twentieth-century Berlin.

    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.

  5. [Staging of scientific facts in syphilis education. "The Shipwrecked" in the Berlin German Theater (1913)].

    The "Deutsche Gesellschaft zur Bekämpfung der Geschlechtskrankheiten" (DGBG) used plays as a means of public education. The play "Damaged Goods" (Les Avariés) by the French dramatist Eugéne Brieux (1858-1932) was used extensively for this purpose in Germany between 1910 and 1920. By proliferating a specific image of both the medical profession and the syphilis, it helped established the self-confidence of the then new dermatological discipline. The teaching of Alfred Fournier (1832-1914) provided the medical background for the play. In "The Inheritance of Syphilis" (1882) Fournier had laid the dramatic framework for Brieux' play. Analyzing the Berlin premiere of "Damaged Goods" on June 25 1913 in the German Theatre/Berlin, the interplay between scientific facts and theatrical license and their diverse influences on the public becomes obvious.

    The population of the Federal Republic of Germany (FRG) was an estimated 61 million (including West Berlin) in 1986 and is in the process of declining gradually as a result of low birth rates. The infant mortality rate is 11/1000, while life expectancy is 73.4 years for women and 67.2 years for men. Of the work force of 27.6 million, 5.4% are engaged in agriculture, 41.6% work in industry and commerce, 10% are employed by the government, and 42.7% are in the service sector. The gross national product was US$898.8 billion in 1986, with an annual growth rate of 2.6% and a per capita income of $10,680. The government is parliamentary and based on a democratic constitution emphasizing protection of individual liberty and divided power in a federal structure. Political life since the establishment of the FRG in 1949 has been characterized by remarkable stability and orderly succession. The FRG ranks among the most important economic powers in the world. The economy is largely export oriented, with 25-30% of the gross national product shipped abroad each year. Competition and free enterprise are fostered, but the state participates in the ownership and management of major sections of the economy, including public services. A major concern at present is the country's ability to adapt to new markets and to develop sophisticated technologies.

  9. Specialist nectar-yeasts decline with urbanization in Berlin

    Nectar yeasts are common inhabitants of insect-pollinated flowers but factors determining their distribution are not well understood. We studied the influence of host identity, environmental factors related to pollution/urbanization, and the distance to a target beehive on local distribution of nectar yeasts within Robinia pseudoacacia L. and Tilia tomentosa Moench in Berlin, Germany. Nectar samples of six individuals per species were collected at seven sites in a 2 km radius from each target beehive and plated on YM-Agar to visualise the different morphotypes, which were then identified by sequencing a section of the 26S rDNA gene. Multivariate linear models were used to analyze the effects of all investigated factors on yeast occurrence per tree. Yeast distribution was mainly driven by host identity. The influence of the environmental factors (NO2, height of construction, soil sealing) strongly depended on the radius around the tree, similar to the distance of the sampled beehive. Incidence of specialist nectar-borne yeast species decreased with increasing pollution/urbanization index. Given that specialist yeast species gave way to generalist yeasts that have a reduced dependency on pollinators for between-flower dispersal, our results indicate that increased urbanization may restrict the movement of nectar-specialized yeasts, via limitations of pollinator foraging behavior.

    OBJECTIVES: Social cohesion is recognized as a fundamental condition for healthy populations, but social cohesion itself arises from political unity. The history of the Berlin Wall provides a unique opportunity to examine the effects of partition on social cohesion and, by inference, on health. METHODS: This ethnographic study consisted of examination of the territory formerly occupied by the Wall, formal and informal interviews with Berlin residents, and collection of cultural documents related to the Wall. Transcripts, field notes, and documents were examined by means of a keyword-in-context analysis. RESULTS: The separation of Berlin into 2 parts was a traumatic experience for the city's residents. After partition, East and West Germany had divergent social, cultural, and political experiences and gradually grew apart. CONCLUSIONS: The demolition of the Wall--the symbol and the instrument of partition--makes possible but does not ensure the reintegration of 2 populations that were separated for 40 years. The evolution of a new common culture might be accelerated by active attempts at cultural and social exchange. PMID:11236400

    The acute respiratory distress syndrome (ARDS) was defined in 1994 by the American-European Consensus Conference (AECC); since then, issues regarding the reliability and validity of this definition have emerged. Using a consensus process, a panel of experts convened in 2011 (an initiative of the European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine) developed the Berlin Definition, focusing on feasibility, reliability, validity, and objective evaluation of its performance. A draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (200 mm Hg < PaO2/FIO2 ≤ 300 mm Hg), moderate (100 mm Hg < PaO2/FIO2 ≤ 200 mm Hg), and severe (PaO2/FIO2 ≤ 100 mm Hg) and 4 ancillary variables for severe ARDS: radiographic severity, respiratory system compliance (≤40 mL/cm H2O), positive end-expiratory pressure (≥10 cm H2O), and corrected expired volume per minute (≥10 L/min). The draft Berlin Definition was empirically evaluated using patient-level meta-analysis of 4188 patients with ARDS from 4 multicenter clinical data sets and 269 patients with ARDS from 3 single-center data sets containing physiologic information. The 4 ancillary variables did not contribute to the predictive validity of severe ARDS for mortality and were removed from the definition. Using the Berlin Definition, stages of mild, moderate, and severe ARDS were associated with increased mortality (27%; 95% CI, 24%-30%; 32%; 95% CI, 29%-34%; and 45%; 95% CI, 42%-48%, respectively; P < .001) and increased median duration of mechanical ventilation in survivors (5 days; interquartile [IQR], 2-11; 7 days; IQR, 4-14; and 9 days; IQR, 5-17, respectively; P < .001). Compared with the AECC definition, the final Berlin Definition had better predictive validity for mortality, with an area under the receiver operating curve of 0.577 (95% CI, 0.561-0.593) vs 0.536 (95% CI, 0.520-0.553; P

    Usutu virus (USUV) is an arbovirus within the genus flavivirus, which was first introduced to Southern Europe approximately twenty years ago causing epizootics among wild and captive birds. In Germany USUV was initially discovered in wild birds, mainly Common blackbirds (Turdus merula), in the Upper Rhine valley in southwest of the country in 2011 and has not spread much northwards since. Phylogenetic analyses revealed that the still ongoing USUV epidemic is caused by two different USUV strains, USUV-Germany belonging to the USUV Europe 3 lineage and USUV-Bonn belonging to the USUV Africa 3 lineage. The two strains were introduced independently. In August 2015 a new USUV strain, named USUV-Berlin, was isolated in Vero cells from two carcasses of juvenile Great grey owls (Strix nebulosa) kept in the Zoological Garden Berlin, which had suffered from a hyperacute fatal systemic infection. Both owls carried high USUV genome loads. Full-length USUV genomes sequences were determined and phylogenetic analysis demonstrated a close relationship with a Spanish mosquito-derived sequence from 2006. Immunohistochemical antigen detection in organ samples of the owls showed the typical USUV infection patterns. According to the phylogenetic analysis, USUV-Berlin belongs to the Africa 2 lineage, and can thus be distinguished from the other strains circulating in Germany. Repeated findings of different USUV strains suggest more frequent introductions into Central Europe and a higher mobility of this virus than assumed to date.

    In acute ischemic stroke, time from symptom onset to intervention is a decisive prognostic factor. In order to reduce this time, prehospital thrombolysis at the emergency site would be preferable. However, apart from neurological expertise and laboratory investigations a computed tomography (CT) scan is necessary to exclude hemorrhagic stroke prior to thrombolysis. Therefore, a specialized ambulance equipped with a CT scanner and point-of-care laboratory was designed and constructed. Further, a new stroke identifying interview algorithm was developed and implemented in the Berlin emergency medical services. Since February 2011 the identification of suspected stroke in the dispatch center of the Berlin Fire Brigade prompts the deployment of this ambulance, a stroke emergency mobile (STEMO). On arrival, a neurologist, experienced in stroke care and with additional training in emergency medicine, takes a neurological examination. If stroke is suspected a CT scan excludes intracranial hemorrhage. The CT-scans are telemetrically transmitted to the neuroradiologist on-call. If coagulation status of the patient is normal and patient's medical history reveals no contraindication, prehospital thrombolysis is applied according to current guidelines (intravenous recombinant tissue plasminogen activator, iv rtPA, alteplase, Actilyse). Thereafter patients are transported to the nearest hospital with a certified stroke unit for further treatment and assessment of strokeaetiology. After a pilot-phase, weeks were randomized into blocks either with or without STEMO care. Primary end-point of this study is time from alarm to the initiation of thrombolysis. We hypothesized that alarm-to-treatment time can be reduced by at least 20 min compared to regular care. PMID:24300505

    A fabric analysis was performed on cyclic grey and black mudstones of lacustrine or fluvial origin from the Lower Jurassic East Berlin Formation near East Berlin, Connecticut. The analysis was to test the utility of macro and microfabric of mudstones in interpreting processes of deposition. The mudstone fabrics were studied with the Scanning Electron Microscope (SEM) and with petrographic techniques using the criteria of O'Brien (1990). Random orientation of clay fabric and grey color are indicators of bioturbation and relatively oxygen-rich environments. The black mudstones show wavy lamination with no evidence of bioturbation. These features coupled with the black color are indicators of relatively oxygen-poor environments. Minor amounts of quartz are found within the clays and crystals of dolomite occur in the black mudstones. SEM analysis shows random clay fabric in both the grey and black mudstones of the East Berlin Formation. On a macroscopic scale, burrows seen in thin sections of the grey mudstone provide clear evidence of bioturbation. The regularity in thickness ([+-] 1 meter) of the black and grey mudstone cycles and the consistent pattern of features in each facies suggests they were deposited in a lacustrine (perennial lake) environment rather than a fluvial environment.

    In Germany, the threat to human health by the small fox tapeworm (Echinococcus multilocularis) has been increasingly discussed in the last few years. On the other hand, the hydatid worm of the dog (Echinococcus granulosus) became more and more rare in Germany and was often declared to be eradicated. This paper presents a case of hydatid infection of the lung in an adult dromedary (Camelus dromedarius), which was born and kept all its life at Tierpark Berlin-Friedrichsfelde. Questions connected with E. granulosus infection are discussed from an ecological point of view: history, urbanisation, biology, clinical signs, potential threat to man, prophylaxis and treatment. In view of the extensive and sometimes uncontrolled dog keeping in urban households it must be stressed that careful documentation and surveillance of this life-threatening zoonosis, which was the main reason for its decline in the past, has not yet lost its importance.

    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 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.

    Alaria alata is a trematode of carnivores from Europe. The mesocercarial stage was recently identified in wild boar meat from Europe. Previous histopathologic studies showed the presence of unidentified parasitic cysts within the tongues of raccoons from northern Germany. For identification of the parasite species, tissue samples of 105 raccoons originating from a National Park in northern Germany and from Berlin metropolitan area were collected. Histological examination of cryotome sections of frozen as well as paraffin-embedded tongues were used to identify parasite cysts. These were located in the connective and adipose tissue and in close proximity to small arterioles, suggesting a hematogenous spread of the parasite. Often, cysts were surrounded with mild infiltration by inflammatory cells. Additionally, mesocercariae were isolated from defrosted tongue samples of 11 raccoons. Molecular-biology assays confirmed the parasite species as A. alata. Except for one positive raccoon from Berlin City, all other positive raccoons originated from the sylvan Müritz National park, indicating an abundance of intermediate hosts in this area. Our results show that raccoons can act as paratenic hosts for A. alata and extend the broad host range of this parasite to a species introduced into Germany.

    The goal of this study is to quantify the influence of fluid-driven heat transport on the subsurface temperature distribution of the city of Berlin, Germany. Berlin is located in the Northeast German Basin filled with several kilometers of sediments. Two of the clastic sedimentary units, namely the Middle Buntsandstein and the Sedimentary Rotliegend are of particular interest for geothermal exploration. Previous studies in the Northeast German Basin have already shown that subsurface temperature distributions are highly dependent on the geometries and properties of the geological units. Our work benefits strongly from these studies that involve numerical modeling of coupled conductive and convective heat transport. We follow a two-step approach where we first improve an existing structural model by integrating newly available 57 geological cross-sections, well data and deep seismics (down to ~4 km). Secondly, we perform a sensitivity analysis in which we investigate the effects of varying physical fluid and rock properties as well as hydraulic and thermal boundary conditions on the resulting temperature configuration. Computed temperatures are validated via comparison with existing well temperature measurements in the area. Of special interest for this study is the influence of the shallow aquifer systems on the subsurface temperature field. The major constituents of this system are the Quaternary silts and sands, the Tertiary Rupelian clay and the Tertiary sands beneath the Rupelian. These units have different hydraulic properties. The Rupelian clay represents a major aquitard in this respect hydraulically disconnecting the pre- and post-Rupelian succession. This aquitard shows a heterogeneous thickness distribution locally characterized by different hydrogeological windows (i.e. domains of no thickness) enabling intra-aquifer groundwater circulation at depth thus having a first-order effect on the shallow thermal field. As result of the simulations, we present

    The nitrate radical is in many situations the most important nighttime oxidizing species, removing, for example, hydrocarbons, which would otherwise be available to daytime ozone formation. In spite of its importance in the night and probably also under certain conditions during the day, our understanding of the NO3 chemistry and its impact on the oxidation capacity of the atmosphere is still incomplete. Here we present measurements of NO3 by differential optical absorption spectroscopy (DOAS) and a number of other atmospheric trace gases performed during the Berliner Ozonexperiment (BERLIOZ) campaign at Pabstthum near Berlin, Germany, to quantify the contribution of NO3 to the atmospheric oxidation rate of volatile organic compounds (VOCs) and NOx removal. The measurements show that only two NO3 sinks were of importance: (1) About 50-30% (depending on the distance (0.1-3 km) to a near forest) of the NO3 was lost due to reaction with biogenic hydrocarbons. (2) The major part of the remaining loss probably can be attributed to the indirect loss via the reaction of N2O5 on aerosol surfaces. Assuming that heterogeneous hydrolysis of N2O5 is occurring, the nonphotolytical conversion of NOx to HNO3 via N2O5 was found to be comparable with daytime conversion by the reaction of OH with NO2. In combination with measurements of the OH concentration, it was possible for the first time to derive a relative contribution of 28% (24-hour average) for the NO3-initiated oxidation to the total VOC degradation.

    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.

    This dissertation explores the milieu in which children of Imperial Berlin were raised. When contemporaries in the rapidly expanding capital of the Second German Empire (1871-1918) looked at children, this milieu darkened. The city, they argued, threatened children's growing bodies, and such institutions as the home, the clinic, and the school…

    A total of 2475 animals from Germany, both captive and wild, were tested for antibodies against Francisella tularensis to obtain more knowledge about the presence of this pathogen in Germany. An indirect and a competitive ELISA served as screening methods, positive and inconclusive samples were confirmed by Western blot. Of the zoo animals sampled between 1992 and 2007 (n = 1122), three (0·3%) were seropositive. The seroconversion of a hippopotamus in Berlin Zoo was documented. From 1353 serum samples of wild foxes (Vulpes vulpes), raccoon dogs (Nyctereutes procyonoides) and wild boars (Sus scrofa), collected between 2005 and 2009 in the federal state of Brandenburg (surrounding Berlin), a total of 101 (7·5%) tested positive for antibodies to F. tularensis lipopolysaccharide. Our results indicate a higher seroprevalence of F. tularensis in wildlife in eastern Germany than commonly assumed. Furthermore, we found foxes and raccoon dogs to be biological indicators for tularaemia.

    1998-06-08

    This study was undertaken for the purpose of analysing under the aspect of legal medicine, fatal accidents due to train surfing in the local transport system of Berlin (S-Bahn and underground). The period of investigation was from 1989 through 1995, with 41 train surfing accidents, among them 18 with fatal outcome. Evaluation included those 14 deaths which were forensically autopsied. It was based on autopsy records of Berlin-based university institutes (Humboldt University and Free University) as well as the Brandenburg State Institute of Legal Medicine. Also used were data obtained from the Berlin Transport Police Record. The casualties were aged between 13 and 25 years, most of them between 16 and 20. The male-female gender ratio was 13:1. Accidents occurred above all in the warmer season of the year, most of them between 20:00 h and midnight. More than 50% of all cases were affected by alcohol, but centrally acting medicaments or other addictive drugs were not noticed at all. Most of the fatal accidents occurred to users of the Berlin S-Bahn network. Older train models were the preferred surfing objects due to their structural peculiarities. Collision with close-to-track obstacles and slipping from the train proved to be the major sources of danger. An analysis of injuries revealed polytraumatisation but for one exception, with craniocerebral injuries being the most common and severest events. The longest survival time amounted to 24 h. As the psychosocial causes of high-risk behaviour of adolescents will hardly be controllable, withdrawal of technical, that is structural design possibilities appears to be the most important approach to prevention of accidents in the future. This demand is met by the new series of the Berlin S-Bahn. The model of the old series, suitable for surfing, still accounts for about 10% of the rolling stock and is to be decommissioned in 1998.

Box 601203, D-14412 Potsdam, Germany Numerous power plants in Europe had to be throttled in the summer months of the years 2003 and 2006 due to water shortages and high water temperatures. Therefore, the effects of climate change on water availability and water temperature, and their effects on electric power generation in power plants have received much attention in the last years. The water demand of a power plant for cooling depends on the temperature of the surface waters from which the cooling water is withdrawn. Furthermore, air temperature and air humidity influence the water demand if a cooling tower is used. Beside climatic parameters, the demand for water depends on economic and technological factors as well as on the electricity demand and the socio-political framework. Since the different systems are connected with certain levels of uncertainty, scenarios of socio-economic development and climate change should be used in analyses of climate change on power plants and to identify adaptation measures. In this presentation the effects of global change, comprising technological, socio-economic and climate change, and adaptation options to water shortages for power plants in the German capital Berlin in the short- and long-term are analysed. The interconnection between power plants, i.e. water demand, and water resources management, i.e. water availability, is described in detail. By changing the cooling system of power

The most dynamic process of aging will take place in the suburban parts of the large western Germany agglomerations, whereas in eastern Germany aging concentrates in regions with a lower density. There will be a regional deconcentration of elderly people with consequences for the planning of infrastructure.

    The history of the 1957/58 Asian flu in Germany is systematically presented for the first time. The focus is on flu vaccination, which is discussed as a yardstick of the perception of the pandemic. International expertise on influenza virology was predominantly based in Anglo-Saxon countries. German microbiologists issued no clear recommendation for preventative vaccination until 1960. Instead, quinine was relied upon as the traditional medicinal prophylaxis. Antibiotics were more frequently administered. In East Germany, little fuss was made over the Asian flu. In line with the authorities' social hygiene orientation, vaccination was accepted as a matter of principle. In the Federal Republic and West Berlin, the population rejected the vaccination largely. It was seen as a scandal that many employees were on sick leave because of the flu, thus adversely affecting the economy.

  2. Berlin Access: an initiative of Berlin SMEs and Fraunhofer-HHI for new FTTH technologies

    "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.

    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.

    F. S. Berlin, N. W. Galbreath, B. Geary, and G. McGlone (this issue) have raised some important questions regarding the use of acturial risk assessment instruments in sex offender civil commitment proceedings, also known as sexually violent predator or SVP proceedings. Their primary point is that interpreting the findings of existing actuarial risk assessment instruments is a tricky business because it is not certain whether the extent to which probability estimates derived from group data can be applied to individual cases. I agree completely with Berlin et al. on this point, but disagree with them concerning the extent to which probability estimates--and, therefore, actuarial instruments--are legally relevant in SVP proceedings. I outline some potential problems with respect to the legal admissibility of actuarial instruments, including their legal relevance.

    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.

  7. Infrared Technology And Public Schools: Applications In Berlin, New Hampshire

    Perrin, Alan F.

    1981-01-01

    Infrared technology played an important part in dealing with school energy problems in Berlin, New Hampshire. It provided the school board and administration with information and data which proved useful in prioritizing the expenditure of limited capital improvement funds. It enabled the board and administration to diagnose the extent of building heat loss problems and compare the heating oil component of our energy problems with independently diagnosed electricity and gasoline components. Since seventy (70) percent of school energy expenditures are on heating oil, infrared assumed the role of a very important diagnostic tool. The Berlin (NH) Public Schools manifest problems faced by public schools in many areas of the country; declining enrollments, inflation, and taxpayer resistance to increasing public expenditures. With eight buildings to heat and light (six schools, a bus garage, and a vocational forestry building), rapidly escalating energy prices threatened to raise total school energy costs as a percentage of total budget from less than seven (7) percent to almost twenty (20) percent, unless consumption reductions were effected. There were minimal obstacles to infrared implementation in Berlin, for a number of reasons. First, the cost was not prohibitive. Second, there was little community understanding of the technology along with an historic separation of specific, relatively low cost school expenditures from close public scrutiny. Finally, the school board and administration realized that, if the energy problem was to be adequately dealt with, a clear understanding of the problem was necessary. The best way for that understanding to be developed was through professional examination of our buildings using the most modern techniques. At this juncture, after only one winter, it is clear that the payback period for Berlin's investment in infrared technology has been surpassed.

    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.

    Between April and July 2011 there was an outbreak of measles virus, genotype D4, in Berlin, Germany. We identified 73 case-patients from the community and among students of an anthroposophic school, who participated in a 4-day school trip, as well as their family and friends. Overall, 27% were aged ≥ 20 years, 57% were female and 15% were hospitalized. Of 39 community case-patients, 38% were aged ≥ 20 years, 67% were female and 63% required hospitalization. Unvaccinated students returning from the school trip were excluded from school, limiting transmission. Within the group of 55 school-trip participants, including 20 measles case-patients, a measles vaccine effectiveness of 97.1% (95% confidence interval 83.4-100) for two doses was estimated using exact Poisson regression. Our findings support school exclusions and the recommendation of one-dose catch-up vaccination for everyone born after 1970 with incomplete or unknown vaccination status, in addition to the two-dose routine childhood immunization recommendation.

    It was the aim of the present study to evaluate how adolescents in Germany accept and consume the new caffeinated drinks (NCD), which can now be legally marketed in Germany. In summer and fall 1994, three surveys were carried out at different schools in Germany, (Aachen, Cologne, Wuppertal, Berlin-West and Berlin-Ost). 1,265 boys and girls were asked for acquaintance with NCD (module I) and 875 of them about consumption (module II). With 727 pupils a third question (module III) was applied by which consumption of Cola drinks compared to that of NCD could be quantified. In total, 93.6% of the young people indicated to know about the NCD, and 53.3% to have tasted these new drinks. Consumption was reported as sometimes (< 1 can/week) from 23% and as repeatedly (1-7 cans/week) from 3%. Acquaintance and consumption were clearly related to age and gender, but even the youngest group (10-13 years old) indicated to have tasted the NCD (30.7% in females and 50% in males) and to drink them sometimes (5.2% in females and 23.1% in males). In the series with question module III 9.5% reported not to drink cola, 36.6% to drink cola "sometimes", 30.9% "repeatedly", 8.6% "often" and 11.6% "frequently" (> 2 cans/day). The corresponding figures for the NCD were 69.9% (non-drinkers), 23.3% "sometimes", 3.3% "repeatedly", 0.3% ten nd 0.6% "frequently". The results suggest that all young people in Germany know about the NCD but actually consume these new drinks moderately. They prefer cola drinks. The observation, however, that a small group may consume extreme amounts and that even very young pupils consume the NCD regularly should give rise to have a close look at the consumption pattern in the near future.

    1995-01-01

    With the fall of the Berlin Wall on November 9, 1989, East Germany entered a process of transition from a centrally planned economy to a market economy. Since then, the number of marriages and births in former East Germany have declined by 65% and 1.3 million people have migrated west. 0.36 million have migrated from West to East Germany. Indeed, the demographic situation in East Germany has fundamentally changed in many ways since 1989. The author analyzes these changes, noting that trends toward deindustrialization and a high level of unemployment especially among women are now basic features of demography in the East. The dismantling of industrial capacities accompanying the economic transformation process in East Germany was not only the result of differences in productivity between East and West Germany, but also of regional strains upon the environment. The author also points out that the economic policy of the former government of East Germany and the resulting environmental damage to the region have not lead to major changes in birth and mortality rates.

    Since 1992, miniaturized pulsatile air-driven ventricular assist devices (VADs), "Berlin Heart," have been used at many institutions (36 cases in North America in 19 different institutions) for pediatric use. Heparin-induced thrombocytopenia (HIT II) is a significant complication rarely reported in the setting of adult VAD support; no similar report exists concerning pediatric VAD support. We report on a 13-month-old, 8.1 kg girl who required LVAD support for cardiogenic shock of unclear etiology. The patient had a history of multiple surgical repairs for correction of complex congenital heart disease consisting of a series of left heart obstructive lesions (Shone's complex). Despite aggressive ventilatory and inotropic support, the patient continued to deteriorate and subsequently required extracorporeal life support. After 7 days of conventional venoarterial extracorporeal membrane oxygenation, a 10 ml Berlin Heart VAD was implanted. After implantation, the patient developed persistent low-grade fever of unclear etiology, gradual thrombocytopenia, and deterioration of renal function. On postimplant day 10, the pump required replacement because of concerns about an inlet valve thrombus; the explanted device demonstrated a nearly occlusive clot not appreciable from external inspection. Simultaneously, HIT II was diagnosed as a result of hematology workup for persistent thrombocytopenia. We discuss the unique challenges posed by HIT II complicating pediatric VAD support and in relation to the heparin coating of the device.

    Remote sensing infrared spectroscopy is the principal field of investigation for planetary surfaces composition. Past, present and future missions to bodies in the solar system include in their payload instruments measuring the emerging radiation in the infrared range. For the interpretation of the measured data an emissivity spectral library of planetary analog materials is needed. The Berlin Emissivity Database (BED) currently contains emissivity spectra of plagioclase and potassium feldspars, low Ca and high Ca pyroxenes, olivine, elemental sulphur, and Martian analogue minerals, measured in the wavelength range from 7 to 22 microns as a function of particle size. For each sample we measured the spectra of four particle size separates ranging from 0 to 250 microns. The device we used is built at DLR (Berlin) and is coupled to a Fourier transform infrared spectrometer (Bruker IFS 88), purged with dry air and equipped with a cooled detector (MCT). All spectra were acquired with a spectral resolution of 4 cm-1. We present here the results of our analysis on well knew and characterized Martian analogue minerals: JSC Mars-1, Salten Skov, and Palagonite from Mauna Kea, Hawaii. We are currently working to upgrade our emissivity facility. A new spectrometer (Bruker VERTEX 80v) and new detectors will allow us to measure the emissivity of samples in the wavelength range from 1 to 50 microns, even in a vacuum environment.

    Early in 1993, the Federal Office for Radiation Protection (BfS, Salzgitter) together with the Federal Environmental Office (UBA, Berlin) established an overall UV monitoring network for the continuous measurement of spectrally resolved UV radiation. Every 6 min the solar UV spectrum is measured by a Bentham DM 150 double monochromator system in a wavelength ranging from 290 to 450 nm. Every night, UV data are automatically transferred via modem to the reference station in Munich where they are quality controlled and then stored in a host computer. Human health assessment of the exposure is documented in 1/2 h MED (minimal erythemal dose) values. The selected sites of Zingst (1 m, 54 degrees N, Baltic Sea), Offenbach (110 m, 50 degrees N, Rhine rift valley), Schauinsland (1205 m, 48 degrees N, Black Forest) and Neuherberg (493 m, 48 degrees N, Munich) provide a good overview of the UV radiation situation in Germany and therefore an ideal supplement to more detailed biological effect research, especially of comparison measurements with biosensors under environmental conditions. Preliminary investigations have already been started.

    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.

    To study the recent contamination history of DDT (1,1,1-trichloro-2,2-bis(chlorophenyl)ethane) and its metabolites, as well as methoxychlor (1,1,1-trichloro-2,2-bis(p-methoxyphenyl)ethane), chlorfenson (4-chlorophenyl-p-chlorobenzenesulfonate), and further halogenated aromatics, a sediment core was collected from the Teltow Canal in Berlin (Germany). The sampling site is located nearby a former industrial point source, where recently analyses on pre-samples have indicated high concentrations of halogenated organic compounds. The deposition time of the investigated sediments was determined by gamma-spectrometrical dating. Pollution trends of selected contaminants were attributed to a time period between 5 and 10 years. Concentration profiles reflect not only the recent pollution history of these compounds, but also the time-depending effects of the ban, restriction and termination of DDT-production in the German Democratic Republic (GDR). DDT and other chlorinated aromatic compounds were produced onsite until the late 1980s. Maximum values of 133 mg kg(-1) (dry weight) for p,p'-DDD (1,1-dichloro-2,2-bis(chlorophenyl)ethane) and approximately 100 mg kg(-1) (dry weight) for p,p'-DDMS (1-chloro-2,2-bis(chlorophenyl)ethane), main metabolites of the anaerobic degradation of DDT, were determined. The occurrence of all selected contaminants, most of which have been banned more than 10 years ago, demonstrate recent contamination pathways, and the necessity of a continuous long-term monitoring of the affected environment.

    This article first shows Jung's evolving views of Nazi Germany from 1936 to the beginning of World War II. In a lecture at the Tavistock Clinic, London, in October 1936, he made his strongest and most negative statements to that date about Nazi Germany. While in Berlin in September 1937 for lectures to the Jung Gesellschaft, his observations of Hitler at a military parade led him to conclude that should the catastrophe of war come it would be far more and bloodier than he had previously supposed. After the Sudetenland Crisis in Fall 1938, Jung in interviews made stronger comments on Hitler and Nazi Germany. The article shows how strongly anti-Nazi Jung's views were in relation to events during World War II such as Nazi Germany's invasion of Poland, the fall of France, the bombings of Britain, the U.S. entry into the War, and Allied troops advancing into Germany. Schoenl and Peck, 'An Answer to the Question: Was Jung, for a Time, a "Nazi Sympathizer" or Not?' (2012) demonstrated how his views of Nazi Germany changed from 1933 to March 1936. The present article shows how his views evolved from 1936 to the War's end in 1945.

    Air pollution is the number one environmental cause of premature deaths in Europe. Despite extensive regulations, air pollution remains a challenging issue, especially in urban areas. For studying air quality in the Berlin-Brandenburg region of Germany the Weather Research and Forecasting Model with Chemistry (WRF-Chem) is set up and evaluated against meteorological and air quality observations from monitoring stations as well as from a field campaign conducted in 2014 (incl. black carbon, VOCs as well as mobile measurements of particle size distribution and particle mass). The model setup includes 3 nested domains with horizontal resolutions of 15km, 3km, and 1km, online biogenic emissions using MEGAN 2.0, and anthropogenic emissions from the TNO-MACC-II inventory. This work serves as a basis for future studies on different aspects of air pollution in the Berlin-Brandenburg region, including how heat waves affect emissions of biogenic volatile organic compounds (BVOC) from urban vegetation (summer 2006) and the impact of selected traffic measures on air quality in the Berlin-Brandenburg area (summer 2014). The model represents the meteorology as observed in the region well for both periods. An exception is the heat wave period in 2006, where the temperature simulated with 3km and 1km resolutions is biased low by around 2°C for urban built-up stations. First results of simulations with chemistry show that, on average, WRF-Chem simulates concentrations of O3 well. However, the 8 hr maxima are underestimated, and the minima are overestimated. While NOx daily means are modeled reasonably well for urban stations, they are overestimated for suburban stations. PM10 concentrations are underestimated by the model. The biases and correlation coefficients of simulated O3, NOx, and PM10 in comparison to surface observations do not show improvements for the 1km domain in comparison to the 3km domain. To improve the model performance of the 1km domain we will include an

    Spatial and social processes are inextricably linked. Hence gender relations as an inherent part of social relations get built into the spatial forms of any society. Spatial segregation by sex was a mark of traditional societies. This has diminished somewhat in contemporary societies due to various factors, perhaps the most important being the entry of women into the public sphere and their participation in income-earning activities. This paper looks at traditional, modern and postmodern housing in two cities--Ahmedabad and Berlin--through the lens of gender and culture. While there have been changes in housing over time, these changes have not been in proportion with the changes in gender relations in society which, in turn, have not kept pace with the way women's needs and priorities have changed. Housing must necessarily reflect the current needs of a society, and that entails reflecting the needs of both women and men equally.

    The contributions of this volume are dedicated to Gottfried Kirch (1639-1710), the first Berlin astronomer, on the occasion of the 300th anniversary of his death. They deal with the astronomy of his times and developments in later times, which are connected to his work. The papers deal with the following topics: The instrumental equipment of Berlin Observatory at the time of G. Kirch and its modernisation up to around 1780; the instruments of Johann Makob Marioni's Viennese observatory around 1730; the heraldic celestial globe by Kirch's teacher Erhard Weigel. In addition, they deal with Kirch's share in the propagation of ideas of the Enlightenment, and with the Berlin meteorological record and its consequences for the investigation of anthropogenous climatic changes. They also deal with astronomical topics in the exchange of letters between Leonhard Euler and Daniel Bernoulli, and with the Berlin "Astronomisches Jahrbuch", which is based on Kirch's activities, as a biographical source.

    2010-01-01

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

    In 2005 and 2006, Francisella tularensis unexpectedly reemerged in western Germany, when several semi-free-living marmosets (Callithrix jacchus) in a research facility died from tularemia and a group of hare hunters became infected. It is believed that hunters may have an elevated risk to be exposed to zoonotic pathogens, including F. tularensis. A previous cross-sectional study of the German population (n=6883) revealed a prevalence of 0.2%. Here, we investigated 286 sera from individuals mainly hunting in districts with emerging tularemia cases (group 1) and 84 sera from a region currently not conspicuous for tularemia (group 2). Methods included standard enzyme-linked immunosorbent assay (ELISA), Western blot analysis and indirect immunofluorescence assay. We found five out of the 286 hunters (1.7%; 95% CI 0.6-4.0%) in group 1 positive with standard ELISA and Western blot, but none in the Berlin area (group 2; 95% CI 0-0.04%). Group 1 showed an elevated risk for hunters to be seropositive for F. tularensis compared with the cross-sectional study (OR=7.7; P<0.001). This indicates a higher prevalence for tularemia in hunters of a suspected endemic region of Germany.

    Sports medicine covers many different aspects, ranging from clinical specialties, such as internal medicine, orthopedics or pediatrics to physiology and sports sciences. The requirements for sports medicine evolve mainly from exercise physiology (elite, leisure and health oriented physical activity), orthopedics and traumatology as well as from preventive and rehabilitative issues. In the new German curriculum, sports medicine is defined as a subspecialty. Historically, sports medicine in Germany has a federal structure with a governing body (Deutsche Gesellschaft für Sportmedizin und Prävention). Due to these facts, University Departments of Sports Medicine (which vary greatly in size and performance) are either attached to Medical or non-Medical Faculties, such as Sports Sciences. In medical schools, sports medicine can be selected as an elective subject. However, the main part of teaching sports medicine is covered by Sports Science Faculties. In an international context, the strength of German sports medicine is its clinical orientation and close cooperation with the sport itself, especially high-performance sports. In the future, like in the Anglo- American countries, sports medicine in Germany will play a major role in health prevention and rehabilitation.

    Prenatal care in Germany is based on a nationwide standardized program of care for pregnant women. Besides support and health counseling, it comprises prevention or early detection of diseases or unfavorable circumstances with risks for mother and child. Prenatal care is regulated by law and structured by directives and standard procedures in maternity guidelines (Mutterschafts-Richtlinien). This includes information and counseling of future mothers on offers of psychosocial and medical assistance in normal pregnancies as well as in unplanned or unwanted pregnancies. Further aspects are clinical examinations and risk determinations for genetic variations or direct genetic analysis. During pregnancy, medical history, clinical examination, and blood testing are part of the sophisticated program, which includes at least three standardized sonographic examinations at 10, 20, and 30 weeks of gestation. The maternity passport allows a pregnant woman to carry the most relevant information on her pregnancy and her personal risks with her. For 45 years now, women in Germany are used to carrying their Mutterpass. Societal changes have influenced the central goals of maternity care: In the beginning, the mortality of mother and child had to be reduced. Today, maternal morbidity and impaired development of the child are the center of interest, with expansion to familial satisfaction. The reduction in the mortality and morbidity of both the mother and the child during pregnancy, delivery, and postpartum can be attributed to prenatal care. Thus, investment in a program of nationwide structured prenatal care seems to be worthwhile-despite the lack of evidence concerning its effectiveness.

    In Germany since 1980, more than 300 clinical studies have been carried out with standardized phytopharmaceuticals, including Crataegus, Silybum, Ginkgo, Hypericum, Sabal, Urtica, Kava-Kava, Allium sativum, Valeriana, Aesculus, Echinacea, and Viscum drugs. These studies assessed the efficacy of phytopharmaceuticals for the treatment of moderate or moderately severe diseases and prevention. Several comparative clinical trials showed that these phytopharmaceuticals had full therapeutic equivalence with chemotherapeutics and had the simultaneous advantage of being devoid of any adverse effects. The mechanism of action of herbal drugs and their extract preparations, which differ in many respects from that of synthetic drugs or mono substances, can be characterized as a polyvalent action and interpreted as additive or, in some cases, potentiating. Currently, a rationale for the observed reversal effects and optimal effects with very low doses after a long-term application has not been developed, but is under investigation by systematic research at the molecular level.

    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.

    1976-09-01

    The concept of cardiac reconditioning centers for the prevention and rehabilitation of coronary patients has been tremendously successful in Germany over the past 20 years. At least 40 such centers are located throughout the country. Physicians, nurses, and physical therapists work closely together in the various facets of the rehabilitation process. The financial backing for these facilities is primarily through governmental and regional insurance companies, whose officials are apparently convinced that in the long run supporting preventive measures is financially sound. Objective data supporting their convictions come from studies such as that of Brusis, who showed that such as that of 1,500 employees was diminished by nearly 70 percent during a two-year period after cardiac reconditioning, as compared to a similar time period before the rehabilitation experience. Subjective benefits, which are extremely difficult to quantitate in meaningful terms, were nonetheless expressed by nearly all the patients with whom I conversed. Perhaps they have experienced the same feelings that Mark Twain did when he observed that "all frets and worries and chafings sank to sleep in the presence of the benignant serenity of the Alps; the Great Spirit of the Mountains breathed his own peace upon their hurt minds and sore hearts and healed them."

    As in probably mostly all other European countries, the incidence of occupational cancer in Germany increased steadily after World War II. In 1994 about 1,600 cases of occupational cancer were compensated--more than ever before. More than half of these cases were lung cancer, most caused either by asbestos (n=545) or by ionizing radiation ((italic)n(/italic)=306). Other frequent target organs of asbestos were the pleura and the peritoneum with 495 cases of mesotheliomas. Asbestos was the single most important risk factor for occupational cancer, causing more than 1000 deaths per year. All other malignant diseases, such as bladder cancer, leukemia, angiosarcoma of the liver, adenocarcinoma of the nose or nasal sinuses, and skin cancer, were comparatively rare. Although primary exposure to ionizing radiation in uranium ore mining occurred in the 1950s and attributable lung cancers seem to be on the decline, this is not true for asbestos, where the peak incidence in lung cancer and mesothelioma has not been reached yet.

    X-ray laser facilities are being constructed all over the world: Linac Coherent Light Source (LCLS) in California, RIKEN X-Ray Free-Electron Laser at SPring-8 in Japan, European XFEL in Germany etc. XFEL is the next-generation (4th) light source. However, the number of such experimental facilities (SRS and FEL) is quite limited. At the same time, relatively small vacuum ultraviolet laboratories with impulse sources [High Harmonic Generators (HHG)] allow one conduct in-house research. This makes the research community directly involved in experiments with time resolution much wider. The latest radiation sources and modern physical experiments require application of the newest diffractive elements. Such diffractive elements are required for implementation of experiments with time resolution using synchrotron radiation sources or high harmonics generators. For example, valence state evolution or molecules dissociation in time-resolved investigation. Modern experiments like this might require implementation of time resolution in femto - (10-15) and even atto- (10-18) seconds.

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

    2010-05-01

    A comparative analysis of municipal solid waste management (MSWM) in Singapore and Berlin was carried out in order to identify its current status, and highlight the prevailing conditions of MSWM. An overview of the various aspects of MSWM in these two cities is provided, with emphasis on comparing the legal, technical, and managerial aspects of MSW. Collection systems and recycling practiced with respect to the involvement of the government and the private sector, are also presented. Over last two decades, the city of Berlin has made impressive progress with respect to its waste management. The amounts of waste have declined significantly, and at the same time the proportion that could be recovered and recycled has increased. In contrast, although Singapore's recycling rate has been increasing over the past few years, rapid economic and population growth as well as change in consumption patterns in this city-state has caused waste generation to continue to increase. Landfilling of MSW plays minor role in both cities, one due to geography (Singapore) and the other due to legislative prohibition (Berlin). Consequently, both in Singapore and Berlin, waste is increasingly being used as a valuable resource and great efforts have been made for the development of incineration technology and energy recovery, as well as climate protection.

  7. Mutualism, resource competition and opposing movements among Turkish organizations in Amsterdam and Berlin, 1965-2000.

    PubMed

    Vermeulen, Floris

    2013-09-01

    This article seeks to understand environmental effects on associational interdependencies, be they competitive or collaborative, in a polarized organizational population. To do so, it builds on the density-dependent model and the ecology of ideologies. Especially interested in the effect of context on density-dependent processes, I compare different Turkish ideological movements in Amsterdam and Berlin. Amsterdam represents an open and supportive environment for such movements, whereas Berlin constitutes a more closed and hostile one. By analysing the founding and disbanding rates of Turkish immigrant organizations in Amsterdam and Berlin during the period 1965-2000, the article demonstrates how the increasing density of Turkish ideologies has affected interdependencies in two main ways: by heightening competition, particularly between ideologically similar organizations, and by increasing counter activities between opposing movements. It also shows that the influence of context is limited. An open environment does not significantly influence the vitality rates of ideologies or further collaboration among or between them. On the contrary, it seemingly increases competition and fragmentation because more resources and opportunities are available. More signs of collaboration and mutualism are found in Berlin's closed environment.

    Eighty pathology cases were sent independently to each of two telepathology servers. Cases were submitted from the Department of Pathology at the University of Kerman in Iran (40 cases) and from the Institute of Pathology in Berlin, Germany (40 cases). The telepathology servers were located in Berlin (the UICC server) and Basel in Switzerland (the iPATH server). A scoring system was developed to quantify the differences between the diagnoses of the referring pathologist and the remote expert. Preparation of the cases, as well as the submission of images, took considerably longer from Kerman than from Berlin; this was independent of the server system. The Kerman delay was mainly associated with a slower transmission rate and longer image preparation. The diagnostic gap between referrers' and experts' diagnoses was greater with the iPATH system, but not significantly so. The experts' response time was considerably shorter for the iPATH system. The results showed that telepathology is feasible for requesting pathologists working in a developing country or in an industrialized country. The key factor in the quality of the service is the work of the experts: they should be selected according to their diagnostic expertise, and their commitment to the provision of telepathology services is critical.

  12. Aerospace medicine in Germany: from the very beginnings.

    PubMed

    Harsch, V

    2000-04-01

    The roots of German Aerospace Medicine are in Berlin. High altitude research was performed by physiologists like Nathan Zuntz and the very first Army flight surgeons, Koschel and Flemming. With the founding of the Scientific Society for Aeronautics in 1912, a medical committee was established to determine guidelines for the physical examination of flyers. In World War I aviation medicine became a military science, which came to an end with the Treaty of Versailles. In 1927, with the establishment of the first Aeromedical Institute in Hamburg, Ludolph Brauer restarted the civilian academic aeromedical research effort, which, thereafter, fell more and more under military influence. At the end of World War II, German scientists were invited to work at the USAAF Aero Medical Center (AMC) in Heidelberg (1945-47), to gather the results of German aeromedical research performed before and during the war. Some of this group of German scientists were invited to work in the USA. In Germany, on the other hand, the effect of this "brain drain" was a period of stagnation. In the 1950's, a new civilian institute of aviation medicine was established in Bonn. It grew to be the nucleus of the DLR Institute of Aviation Medicine in Cologne. The German Air Force Institute of Aviation Medicine was founded in Fuerstenfeldruck in 1959, and in the GDR the Institute of Aviation Medicine was established in 1961: the first East German cosmonaut S. Jaehn 1978 (Soyuz-31), was succeeded by the first West German astronaut, U. Merbold in 1983 (Spacelab).

    Obstructive Sleep Apnea (OSA) is a common disease associated with major cardiovascular diseases. Male subjects are more at higher risk for OSA than female subjects. The Berlin questionnaire is a beneficial screening tool for OSA and has 14 items. The Berlin questionnaire may need some adjustment for Thai or Asian populations. We aimed to find items that should be asked in the Berlin questionnaire to identify high risk for obstructive sleep apnea among Thai male healthcare workers. This study was performed in Thai male healthcare workers over the age of 35 and currently working at the Faculty of Medicine, Khon Kaen University. The Thai version of the Berlin questionnaire was randomly distributed. A study population of 273 subjects was required to provide a confidence value of 95%. An item analysis of the Berlin questionnaire was evaluated as independent factors for being high risk of OSA by using a multivariate logistic regression analysis. Of the 273 distributed questionnaires, 135 subjects returned then (49.5% response rate). Of those, 41 (30.4%) were identified as being at high risk of OSA. Only three items of the Berlin questionnaire, including frequent snoring, high body mass index and hypertension, were independently associated with being at high risk for OSA. In conclusion, the Berlin questionnaire can be shortened to identify high risk for OSA by itself; not polysomnography.

    The wall-less bacteria of the provisory taxon 'Candidatus Phytoplasma' are obligate parasites and associated to diseases in many important crops and trees worldwide. 'Ca. Phytoplasma ulmi', assigned to 16SrV-A subgroup, is a quarantine pest and described to be associated to elm phloem necrosis, leaf yellowing, stunting, witches broom and decline in various elm species. Elm yellows phytoplasmas (EY) have been reported in several European countries but not in Ulmus laevis in Germany so far. Leaf samples from European white elms (Ulmus leavis PALL.) with and without chlorotic symptoms were investigated for EYs infection in Berlin and Brandenburg, Germany, through performing diagnostic nested PCR targeting partial rRNA operon of phytoplasmas. Specific PCR-products were obtained from 30 out of 59 samples. Partial 16S-rDNA sequences were assigned to 'Ca. P. ulmi' through sequence analysis, while sequence variation was observed. This is the first report of U. laevis infected with 'Ca. P. ulmi' in Germany.

    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-wise measurement of volatile

    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.

    Questions: There are no current health care studies from Germany regarding the "morning-after pill". This paper will use routine data to analyse details regarding the users' profiles, reasons for using it and the utilisation of hospital outpatient facilities. Patient Collective and Methods: Retrospective analysis of all triage sheets in the emergency department of the Virchow Hospital Campus/Charité University Hospital, Berlin, over a four-year period from 2007 to 2010 that were coded with the ICD diagnosis Z30 (= contraception advice) and statistical processing of the associated administrative data. Results: 860 triage sheets were included in the analysis. The emergency department is used most frequently for the prescription of the "morning-after pill" at the weekend. The average age of the users was 25.1 years. The most common reason cited for needing emergency contraception was unprotected sexual intercourse, with the second-most common being "condom failure". Around half of the women attended the department within 12 hours of having unprotected sex. Less than 2 % (n = 14) of all women decided against a prescription of emergency contraceptive after counselling. Conclusions: The user profile and reasons for using emergency oral contraception correlate largely with the information contained in international literature. Although the "morning-after pill" is probably prescribed mainly in general practices in Germany, and despite the availability of new drugs with a permitted post-exposure interval of up to 120 hours after unprotected sex, there appears to still be a high demand for counselling and prescriptions of the "morning-after pill" in the context of the emergency department.

  3. Water and bed-sediment quality in the vicinity of Berlin Lake, Ohio, 2001

    Berlin Lake, in northeast Ohio, was created by the U.S. Army Corps of Engineers in 1943 and is used primarily for flood control for the upper reaches of the Mahoning River. The area surrounding and under the lake has been tapped for oil and natural gas production. One of the by-products of oil and gas production is concentrated salt water or brine, which might have an effect on the chemical quality of area potable-water sources. This report presents the results of a U.S. Geological Survey baseline study to collect current (2001) water and sediment-quality data and to characterize water quality in the Berlin Lake watershed. Chloride-to-bromide ratios were used to detect the presence of brine in water samples and to indicate possible adverse effects on water quality. Analyses of ground-water samples from domestic wells in the area indicate a source of chloride and bromide, but defining the source would require more data collection. Analyses of specific conductance and dissolved solids indicate that 78 percent (14 of 18) of the ground-water samples exceeded the Secondary Maximum Contaminant Level for dissolved solids in public water supplies of 500 milligrams per liter (mg/L), compared to 6 percent of samples exceeding 500 mg/L in two nearby studies. Surface water was analyzed twice, once each during low-flow and surface runoff conditions. A comparison of the 2001 data to historical chloride concentrations, accounting for seasonal changes, does not indicate an increase in chloride loads for surface water in the area of Berlin Lake. Polycyclic aromatic hydrocarbons were found in bed-sediment samples collected from the mouths of major tributaries to Berlin Lake. Polycyclic aromatic hydrocarbons are produced during the incomplete combustion of organic carbon materials such as wood and fossil fuels, and they are components of petroleum products.

  4. [History as politics. Medical historians in Berlin and Graz serving the NS-State].

    PubMed

    Bruns, Florian; Frewer, Andreas

    2005-01-01

    History of medicine played an important part in the ideology and policy of the Third Reich. The Nazi Party and the "Schutzstaffel" (SS) tried to instrumentalize historical knowledge to justify their ideology and medical ethics. The academic discipline of the history of medicine saw a revival during the Nazi period and, especially, during the Second World War. Important medical historians were eager to contribute to a symbiosis between the State and their field. The close relationship between the history of medicine and the Nazi regime was particularly apparent at Paul Diepgen's Department for the History of Medicine and Natural Sciences at the University of Berlin. Diepgen, apart from his own collaboration with the Nazi regime, was the teacher of Bernward J. Gottlieb who became the leading medical historian of the SS and Director of the new "SS-Institute for the History of Medicine" in Berlin in 1941. Gottlieb's institute moved in 1943 to the "SS-Academy" in Graz to train future SS-physicians in the history of medicine. The history of medicine was of great relevance also for certain members of the Nazi elite. They included Heinrich Himmler, the head of the SS, who ensured that Gottlieb would become Diepgen's successor in 1945 for the chair of medical history at the University of Berlin. Hitler was asked to intervene in the appointment process given the political importance of the field and, in particular, the professorship being located in Berlin. The SS was able to exercise, by this time, a decisive influence on the field of the history of medicine. Only the collapse of the Third Reich prevented the traditional discipline from becoming a "science" to legitimize the Nazi System and the SS. The aim of this paper is to examine the role of the field of the history of medicine and of its key institutions and personalities during the Third Reich.

    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.

    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 detection

    The purpose of this article is to give international readers an overview of the organisation, structure and curriculum, together with important advances and problems, of undergraduate medical education in Germany. Interest in medical education in Germany has been relatively low but has gained momentum with the new "Regulation of the Licensing of Doctors" which came into effect in 2003. Medical education had required substantial reform, particularly with respect to improving the links between theoretical and clinical teaching and the extension of interdisciplinary and topic-related instruction. It takes six years and three months to complete the curriculum and training is divided into three sections: basic science (2 years), clinical science (3 years) and final clinical year. While the reorganisation of graduate medical education required by the new "Regulation of the Licensing of Doctors" has stimulated multiple excellent teaching projects, there is evidence that some of the stipulated changes have not been implemented. Indeed, whether the medical schools have complied with this regulation and its overall success remains to be assessed systematically. Mandatory external accreditation and periodic reaccreditation of medical faculties need to be established in Germany. PMID:19675742

    Objectives Men who have sex with men (MSM) are at higher risk for coinfection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis than the general population. HIV infection and these coinfections accelerate disease progression reciprocally. This study evaluated the prevalence and incidence of these coinfections in HIV1-positive MSM in Germany. Materials and Methods As part of a nationwide, multicenter, prospective cohort study of HIV-infected MSM, plasma samples collected yearly were screened for HBsAg and antibodies to HBc, HBs, HCV, and syphilis. Samples with indications of active HBV or HCV infection were confirmed by polymerase chain reaction. Prevalence and incidence of each infection and incidence rates per study participant were calculated, and incidences over 4-year time intervals compared. Results This study screened 5,445 samples from 1,843 MSM. Median age at HIV seroconversion was 33 years. Prevalences of active, cleared, and occult HBV, and of active/cleared HCV were 1.7%, 27.1%, 0.2%, and 8.2%, respectively, and 47.5% had been effectively vaccinated against HBV. Prevalence of antibodies to Treponema pallidum and of triple or quadruple sexually transmitted infections (STIs) were 39.6% and 18.9%, respectively. Prevalence of STI, cleared HBV, HBV vaccination, and history of syphilis differed significantly among age groups. Incidences of HBV, HCV, and syphilis were 2.51, 1.54, and 4.06 per 100 person-years, respectively. Incidences of HCV and syphilis increased over time. HCV incidence was significantly higher in MSM coinfected with syphilis and living in Berlin, and syphilis incidence was significantly higher for MSM living in Berlin. Discussion Despite extensive HBV vaccination campaigns, fewer than 50% of screened MSM were effectively vaccinated, with a high proportion of HIV-positive MSM coinfected with HBV. High rates of STI coinfections in HIV-positive MSM and increasing incidences emphasize the need for better tailored campaigns for

    Study Objectives: Following the 2009 pandemic, reports of an association between an AS03 adjuvanted H1N1 pandemic influenza vaccine and narcolepsy were published. Besides determining background incidence rates for narcolepsy in Germany this study aimed at investigating whether there was a change in incidence rates of narcolepsy between the pre-pandemic, pandemic, and the post-pandemic period on the population level. Design: Retrospective epidemiological study on the incidence of narcolepsy with additional capture-recapture analysis. Setting: German sleep centers. Patients or Participants: Eligible were patients with an initial diagnosis of narcolepsy (ICD10 Code G47.4) within the period from January 1, 2007 to December 31, 2011. Interventions: None; observational study. Measurements and Results: A total of 342 sleep centers were invited to participate in the study. Adequate and suitable data were provided by 233 sleep centers (68.1%). A total of 1,198 patients with an initial diagnosis of narcolepsy within the observed period were included, of whom 106 (8.8%) were children and adolescents under the age of 18 years and 1,092 (91.2%) were adults. In children and adolescents, the age-standardized adjusted incidence rate significantly increased from 0.14/100,000 person-years in the pre-pandemic period to 0.50/100,000 person-years in the post-pandemic period (incidence density ratio, IDR 3.57; 95% CI 1.94–7.00). In adults, no significant change was detectable. This increase started in spring 2009. Conclusions: For the years 2007–2011, valid estimates for the incidence of narcolepsy in Germany were provided. In individuals under 18, the incidence rates continuously increased from spring 2009. Citation: Oberle D, Drechsel-Bäuerle U, Schmidtmann I, Mayer G, Keller-Stanislawski B.

    2014-03-01

    Outpatient rheumatologic treatment in Germany is managed by rheumatologists in private practice (n = 557), by authorized rheumatism outpatient centers (n = 116), by rheumatism centers according to §116b (n = 43) and by university outpatient departments. A total number of 975 rheumatologists were registered by the end of 2012 of whom approximately 830 were active in outpatient care. With this number of rheumatologists Germany is in the middle range in comparison to eight industrial nations including the USA. This number is not sufficient to provide adequate medical care and the consequences are too long waiting times for an appointment with a rheumatologist. Statistical data of the Kassenärztliche Bundesvereinigung (KBV, National Association of Statutory Health Insurance Physicians) showed 688,000 general insurance patients with rheumatoid arthritis (RA). As some 68.9 % of the population are in this insurance scheme there are some 770,000 RA patients in Germany (almost 1 % of the population). One way to improve rheumatology care in spite of the lack of rheumatologists could be special agreements with the general health insurance providers to improve cooperation and division of responsibilities between rheumatologists and general practitioners, to implement patient education, tighter control and treat to target in rheumatology care. Another way could be a new treatment level called "ambulant specialist care", with no budget for medical care and no budget for the number of patients treated and therefore the chance for rheumatologists to treat more patients and have a better income. To achieve that more young doctors receive approval as a specialist in rheumatology, more chairs of rheumatology at universities and a nationwide stipendium for training assistants are needed.

    The therapy of eye tumors with fast protons is an excellent tool giving very high local control rates. At the Helmholtz-Zentrum Berlin (HZB) almost 1800 patients were treated since 1998. A 2 MV Tandetron was installed as injector for the k = 132 HZB cyclotron. Using the standard 358 duoplasmatron ion source with direct extraction of negative hydrogen ions an extremely stable proton beam can be delivered, both on the short-term and the long-term scale. The hair-needle filaments made from thoriated tungsten wires have safe operation times of more than 1000 h.

    We use the derivative of the electron density with respect to the reaction coordinate, interpreted through the Berlin binding function, to identify portions of the reaction path where chemical bonds are breaking and forming. The results agree with the conventional description for SN2 reactions, but they are much more general and can be used to elucidate other types of reactions also. Our analysis offers support for, and detailed information about, the use of the reaction force profile to separate the reaction coordinates into intervals, each with characteristic extents of geometry change and electronic rearrangement.

    In the years 1821 and 1822 two books offered contradictory accounts of a scandal in Berlin involving sexual abuse in connection with magnetism. Historical research has determined that the accused was the famous physician and magnetizer Karl Christian Wolfart. If, however, we look more closely at the general context, it appears that this was not just a case of abuse of the therapeutic relationship. Rather, it is suggested that a specific combination of therapeutic ignorance and particular psycho-social influences contributed almost inevitably to the abuse of patients--sexually or otherwise.

  19. German genes and Turkish traits: ethnicity, infertility, and reproductive politics in Germany.

    PubMed

    Vanderlinden, Lisa K

    2009-07-01

    This ethnographic study uses the lens of ethnic difference to examine the experience of infertility and the cultural politics of belonging in modern Germany. The data are derived from participant observation and interviews conducted with forty-one ethnic Germans and thirty-three German Turks undergoing biomedical treatment for infertility at a fertility clinic in Berlin (1998-2000). Through their illness narratives, men and women symbolically link their loss of biological parenthood to losses in other life arenas, such as gender identity, social status and cultural acceptance. Results reveal that while both German Turks and ethnic Germans experience disruption and social suffering from their inability to conform to procreative norms, German Turkish sufferers exhibit higher levels of distress, which directly relates to their dual stigma as outsiders in both German Turkish culture and mainstream German culture. The findings suggest that the tensions surrounding individual reproductive practices are reflective of larger national tensions regarding the constitution of the body politic in an increasingly multicultural Germany.

    Domestic violence and sexual violence are widespread and have serious health effects for those affected. If the problem is identified and confidence in responding exists, healthcare providers can make a significant contribution to support and intervention. In 2013 the WHO published evidence-based guidelines for responding to the issue in healthcare, training of healthcare providers and health policy. In principle, the guidelines confirm existing recommendations, best-practice guidelines and handbooks. They also encourage a review and further development-for example, regarding the issue of sexual violence. If and how the present recommendations are put into practice in healthcare and training of healthcare staff can currently be looked at only with the use of examples, given the lack of data in Germany. Examples from Berlin show that implementation is quite possible. However, there is a lack of clear mandate, of sustainability and of obligation. Existing good practice models are highly reliant on organisations' and employees' commitment. For Germany, the WHO guidelines indicate the need to develop national standards for healthcare in cases of domestic and sexual violence. A (legal) obligation for the healthcare system should be drawn up. A systematic embedding in training curricula of health care professions is needed. Quality assurance and a systematic evaluation of the practical implementation are required.

    In 1996 a new epidemic MRSA emerged in three hospitals North of Berlin. This strain, Barnim epidemic MRSA, was isolated in 15 hospitals in Northern Germany in 1997 and 29 hospitals throughout Germany in 1998. Isolates of this clone are non-typeable by phages, its resistance phenotype is PEN, OXA, ERY, CLI, CIP (genotype: mecA, ermC, mutations in grlA and gyrA). The Sma I macrorestriction pattern corresponds to particular phage group II strains which is confirmed by the 16S-23S rRNA gene spacer pattern. Isolates of this clone differ by less than three Sma I macrorestriction fragments from isolates of the EMRSA15 clone from the United Kingdom, the most common epidemic MRSA isolates in the United Kingdom in recent years. Both epidemic strains produce enterotoxin C and possess the sec determinant for this toxin, the configuration of the mec regulon is mecI-, mecRB+, mecRC+. Both share the same Alu I pattern of PCR amplimers of the 3' end region of the coagulase gene. EMRSA 15 and Barnim EMRSA share a common multilocus sequence type indicating a recent, shared evolutionary origin.

    2013-01-01

    Summary Comparing two public medical affairs which involved disciplinary proceedings and libel actions, one from Bavaria and one from Prussia, this article analyzes the dynamics behind legal conflicts over doctors’ professional ethics in Imperial Germany. In both the case of Dr Maurice Hutzler, who committed suicide after conflicts with senior colleagues at the Gisela Children’s Hospital and a sentence of the court of honour of the Munich Medical District Society, and the Berlin ‘patient trade’ affair, in which the medical professors Ernst von Leyden, Hermann Senator, Karl Anton Ewald and Carl Posner were accused of having made payments to middlemen for bringing them lucrative private patients, notions of personal and professional honour played a central role. The Munich case highlighted shortcomings of the Bavarian medical court of honour system, which was less developed than its Prussian counterpart. The analysis of the two cases suggests that the ethics of medical practice in early twentieth-century Germany should be viewed as part of a culture of honour. PMID:22303773

    Herb-induced liver injury (HILI) has recently attracted attention due to increasing reports of hepatotoxicity associated with use of phytotherapeutics. Here, we present data on HILI from the Berlin Case-Control Surveillance Study. The study was initiated in 2000 to investigate the serious toxicity of drugs including herbal medicines. Potential cases of liver injury were ascertained in more than 180 Departments of all 51 Berlin hospitals from October 2002 to December 2011. Drug or herb intake was assessed through a standardized face-to-face interview. Drug or herbal aetiology was assessed based on the updated Council for International Organizations of Medical Sciences scale. In ten of all 198 cases of hepatotoxicity included in the study, herbal aetiology was assessed as probable (once ayurvedic herb) or possible (Valeriana five times, Mentha piperita once, Pelargonium sidoides once, Hypericum perforatum once, Eucalyptus globulus once). Mean age was 56.4 ± 9.7 years, and the predominant pattern of liver injury was hepatocellular. No cases of acute liver failure or death were observed. This case series corroborates known risks for ayurvedic herbs, supports the suspected association between Valeriana use and liver injury, and indicates a hepatotoxic potential for herbs such as Pelargonium sidoides, Hypericum perforatum or Mentha piperita that were rarely associated with liver injury before. However, given that possible causality does not prove clinical significance, further studies in this field are needed. PMID:26784183

    The design and first applications of a new tandem mass spectrometer (BerlinTrap) combining an electrospray ion source, a quadrupole mass spectrometer, a cryogenic 22-pole ion trap (4-300 K), and an orthogonal reflectron time-of-flight mass spectrometer are described. The trapped ions are cooled by helium buffer gas cooling. The formation and solvation shell structure of weakly-bound HenH3O+ complexes and the electronic photodissociation spectrum of the protonated amino acid tyrosine are used to calibrate the setup for cooling, tagging, and spectroscopic capabilities. A vibrational temperature below 20 K is inferred for protonated tyrosine. The electronic spectrum of isolated protonated lumichrome, the smallest protonated flavin, is recorded in the visible range and assigned to the most stable N5 isomer by comparison with quantum chemical calculations. These results demonstrate the suitability of the BerlinTrap apparatus for spectroscopy and reactivity studies of small and large (bio-)molecular ions and their clusters.

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

    PubMed

    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.

    This article describes the development of a model to simulate the fate of iodinated X-ray contrast media (XRC) in the water cycle of the German capital, Berlin. It also handles data uncertainties concerning the different amounts and sources of input for XRC via source densities in single districts for the XRC usage by inhabitants, hospitals, and radiologists. As well, different degradation rates for the behavior of the adsorbable organic iodine (AOI) were investigated in single water compartments. The introduced model consists of mass balances and includes, in addition to naturally branched bodies of water, the water distribution network between waterways and wastewater treatment plants, which are coupled to natural surface waters at numerous points. Scenarios were calculated according to the data uncertainties that were statistically evaluated to identify the scenario with the highest agreement among the provided measurement data. The simulation of X-ray contrast media in the water cycle of Berlin showed that medical institutions have to be considered as point sources for congested urban areas due to their high levels of X-ray contrast media emission. The calculations identified hospitals, represented by their capacity (number of hospital beds), as the most relevant point sources, while the inhabitants served as important diffusive sources. Deployed for almost inert substances like contrast media, the model can be used for qualitative statements and, therefore, as a decision-support tool.

    Abstract Background Urban green spaces can harbor a considerable species richness of plants and animals. A few studies on single species groups indicate important habitat functions of cemeteries, but this land use type is clearly understudied compared to parks. Such data are important as they (i) illustrate habitat functions of a specific, but ubiquitous urban land-use type and (ii) may serve as a basis for management approaches. New information We sampled different groups of plants and animals in the Weißensee Jewish Cemetery in Berlin (WJC) which is one of the largest Jewish cemeteries in Europe. With a total of 608 species of plants and animals, this first multi-taxon survey revealed a considerable biological richness in the WJC. In all, 363 wild-growing vascular plant, 72 lichen and 26 bryophyte taxa were recorded. The sampling also yielded 34 bird and 5 bat species as well as 39 ground beetle, 5 harvestman and 64 spider species. Some species are new records for Berlin. PMID:27099549

The numerical calculations using Mie theory has been carried out for three-layered metal nanoshell dielectric-metal-metal (DMM) system consisting of a particle with a dielectric core (Al@Al2O3), a middle metal Ag (Au) layer and an outer metal Au (Ag) shell. The results have been interpreted using plasmon hybridization theory. We have also prepared Al@Al2O3@Ag@Au and Al@Al2O3@AgAu triple-layered core-shell or alloy nanostructure by two-step laser ablation method and compared with calculated results. The synthesis involves temporal separations of Al, Ag, and Au deposition for step-by-step formation of triple-layered core-shell structure. To form Al@Ag nanoparticles, we ablated silver for 40 min in aluminium nanoparticle colloidal solution. As aluminium oxidizes easily in water to form alumina, the resulting structure is core-shell Al@Al2O3. The Al@Al2O3 particle acts as a seed for the incoming energetic silver particles for multilayered Al@Al2O3@Ag nanoparticles is formed. The silver target was then replaced by gold target and ablation was carried out for different ablation time using different laser energy for generation of Al@Al2O3@Ag@Au core-shell or Al@Al2O3@AgAu alloy. The formation of core-shell and alloy nanostructure was confirmed by UV-visible spectroscopy. The absorption spectra show shift in plasmon resonance peak of silver to gold in the range 400-520 nm with increasing ablation time suggesting formation of Ag-Au alloy in the presence of alumina particles in the solution.

  13. History of modern genetics in Germany.

    Hammar, Friederike

    The history of modern genetics in Germany during the 20th century is a story of missed chances. In the USA the genetic revolution opened a fascinating new field for ambitious scientists and created a rapidly growing new industry. Meanwhile Germany stood aside, combating with political and social restrictions. Promising young scientists who wanted to work in the field left Germany for the US, and big companies moved their facilities out of the country. Up until the middle of the 1990s molecular biology in Germany remained a "sleeping beauty" even though many brilliant scientists did their jobs very well. Then a somewhat funny idea changed everything: the German minister for education and science proclaimed the BioRegio contest in order to award the most powerful biotechnology region in Germany concerning academia and especially industry. Since then Germany's biotechnology industry has grown constantly and rapidly due to the foundation of a number of small biotech companies; big companies have returned their interests and their investments to Germany, paralleled by an improvement in academic research because of more funding and better support especially for younger scientists. In respect to biotechnology and molecular biology, Germany is still a developing country, but it has started to move and to take its chances in an exciting global competition.

  14. Children's "euthanasia" in Nazi Germany.

    2009-12-01

    Children with disabilities were killed during the Nazi era, often by nurses. Some nurses killed children, saying that they were under orders. Propaganda about the need for "racial purity" was all pervasive and influenced much of the population, including nurses. The German people accepted the "mercy" killing of children with disabilities. We describe the children's "euthanasia" program, explore the influence of propaganda, ask why it was acceptable to kill children, and provide historical context demonstrating "slippery slopes" which can lead to abrogation of ethical principles. Discussion of such history is essential as the ethical principles which were breached are still the cornerstone of nursing practice today. Only by openly discussing past wrongs can we attempt to ensure that they do not happen again. Archival documents from Germany and Israel, including trial depositions and transcripts, provided material, supplemented by secondary classic sources.

  8. "God save us from psychologists as expert witnesses": the battle for forensic psychology in early twentieth-century Germany.

    PubMed

    Wolffram, Heather

    2015-11-01

    This article is focused on the jurisdictional battle between psychiatrists and psychologists over psychological expertise in legal contexts that took place during the first decades of the 20th century. Using, as an example, the debate between the psychologist William Stern, the psychiatrist Albert Moll, and the jurist Albert Hellwig, which occurred at the International Congress for Sexual Research held in Berlin in 1926, it aims to demonstrate the manner in which psychiatrists' responses to psychologists' attempts to gain admittance to Germany's courtrooms were shaped not only by epistemological and methodological objections, but also by changes to expert witnessing that had already encroached on psychiatrists' professional territory. Building upon recent work examining the relationship between psychologists and jurists prior to the First World War, this article also seeks to examine the role of judges and lawyers in the contest over forensic psychology in the mid-1920s, arguing that they ultimately became referees in the increasingly public disputes between psychiatrists and psychologists.

    From December 2012 to May 2013, an outbreak occurred among urban wild carnivores from Berlin. We collected 97 free-ranging raccoons from the city area. PCR assays, histopathology and immunohistochemistry confirmed canine distemper virus (CDV) infection in 74 raccoons. Phylogenetic analysis of haemagglutinin gene fragments (1767 nucleotides) of CDV isolated from four raccoons showed close relation to CDV isolates from foxes from Germany and a domestic dog from Hungary; all belonging to the "Europe" lineage of CDV. These study results suggest an inter-species transmission of CDV as the origin for the outbreak among the raccoon population. Implications for domestic pets and suggested interspecies transmission between urban wildlife and raccoons are discussed. This is the first major outbreak of CDV amongst free-ranging raccoons in Europe.

    Land Surface Temperature (LST) is defined as the temperature of the interface between the Earth's surface and its atmosphere and thus it is a critical variable to understand land-atmosphere interactions and a key parameter in meteorological and hydrological studies, which is involved in energy fluxes. Air temperature (Tair) is one of the most important input variables in different spatially distributed hydrological, ecological models. The estimation of near surface air temperature is useful for a wide range of applications. Some applications from traffic or energy management, require Tair data in high spatial and temporal resolution at two meters height above the ground (T2m), sometimes in near-real-time. Thus, a parameterization based on boundary layer physical principles was developed that determines the air temperature from remote sensing data (MODIS). Tair is commonly obtained from synoptic measurements in weather stations. However, the derivation of near surface air temperature from the LST derived from satellite is far from straight forward. T2m is not driven directly by the sun, but indirectly by LST, thus T2m can be parameterized from the LST and other variables such as Albedo, NDVI, Water vapor and etc. Most of the previous studies have focused on estimating T2m based on simple and advanced statistical approaches, Temperature-Vegetation index and energy-balance approaches but the main objective of this research is to explore the relationships between T2m and LST in Berlin by using Artificial intelligence method with the aim of studying key variables to allow us establishing suitable techniques to obtain Tair from satellite Products and ground data. Secondly, an attempt was explored to identify an individual mix of attributes that reveals a particular pattern to better understanding variation of T2m during day and nighttime over the different area of Berlin. For this reason, a three layer Feedforward neural networks is considered with LMA algorithm

    Mobil Oil AG, West Germany, added 20 bcf of natural gas to the field reserves and improved well productivity five-fold through a massive fracture of the Mainsand section of the Upper Rotliegendes formation in Soehlingen field. The frac job was the largest ever in Europe and is felt to be the world's largest in terms of sintered bauxite used. The fracture treatment also showed that it is possible to put 9,000 lb/min of bauxite into a hydraulically formed fracture. This is believed to be a record rate for this high-strength proppant. Mobil engineers feel, however, that Ottawa sand could probably be used, and they may try it if another opportunity presents itself.

    Zoonotic hepatitis E virus (HEV) infection in industrialised countries is thought to be caused by transmission from wild boar, domestic pig and deer as reservoir hosts. The detection of HEV-specific antibodies in rats and other rodents has suggested that these animals may represent an additional source for HEV transmission to human. Recently, a novel HEV (ratHEV) was detected in Norway rats from Hamburg, Germany, showing the typical genome organisation but a high nucleotide and amino acid sequence divergence to other mammalian and to avian HEV strains. Here we describe the multiple detection of ratHEV RNA and HEV-specific antibodies in Norway rats from additional cities in north-east and south-west Germany. The complete genome analysis of two novel strains from Berlin and Stuttgart confirmed the association of ratHEV to Norway rats. The present data indicated a continuing existence of this virus in the rat populations from Berlin and Hamburg. The phylogenetic analysis of a short segment of the open reading frame 1 confirmed a geographical clustering of the corresponding sequences. Serological investigations using recombinant ratHEV and genotype 3 capsid protein derivatives demonstrated antigenic differences which might be caused by the high amino acid sequence divergence in the immunodominant region. The high amount of animals showing exclusively ratHEV RNA or anti-ratHEV antibodies suggested a non-persistent infection in the Norway rat. Future studies have to prove the transmission routes of the virus in rat populations and its zoonotic potential. The recombinant ratHEV antigen generated here will allow future seroepidemiological studies to differentiate ratHEV and genotype 3 infections in humans and animals.

    2005-01-01

    The 5th annual European League Against Rheumatism congress, held in Berlin, 9–12 June 2004, was attended by a record number of delegates from all continents and offered a large choice of education, state-of-the-art and original research presentations in up to 15 parallel sessions. Some of these were poorly attended, although featuring top-ranked abstracts. The poster sessions remain a problem child. They were not well attended by viewers and largely neglected by presenters, mainly because of the general structure of the meeting. Ways to improve this could be to provide lunch packages and to appoint poster session chairmen. Other changes would involve moving morning hour satellites to other slots. However, in general it was an enjoyable meeting showing important progress in various fields of rheumatology and meeting the expectations of most delegates.

  15. A systemic-wholistic approach to differential aging: longitudinal findings from the Berlin Aging Study.

    PubMed

    2006-12-01

    Wholistic perspectives on differential change focus on multiple-indicator information at a person level. They supplement the modeling of average trajectories at a variable level. The authors extended cross-sectional work in the Berlin Aging Study (J. Smith & P. B. Baltes, 1997) to 6-year longitudinal cluster analyses (n = 132). At baseline, 3 subgroups were identified with distinct within-person psychological profiles across cognitive, personality, and social integration constructs. Over time, highly similar subgroup profiles were found, and about two thirds of the participants could be classified as remaining in the same subgroups. Baseline subgroups differed in level and slope of change and in 2 outcomes, well-being and mortality. Independent of subgroup membership, subgroup-to-subgroup change was associated with greater decline and predicted poststudy mortality. These findings demonstrate the usefulness of a wholistic approach for long-term prediction of outcomes and within-person systemic variability.

    For BERLinPro, a 100 mA CW-driven SRF energy recovery linac demonstrator facility, HZB needs to develop a photo-injector superconducting cavity which delivers a at least 1mm*mr emittance beam at high average current. To address these challenges of producing a high peak brightness beam at high repetition rate, at first HZB tested a fully superconducting injector with a lead cathode*,followed now by the design of a SC cavity allowing operation up to 4 mA using CW-modified TTF-III couplers and inserting a normal conducting high quantum efficiency cathode using the HZDR-style insert scheme. This talk will present the latest results and an overview of the measurements with the lead cathode cavity and will describe the design and optimization process, the first production results of the current design and an outlook to the further development steps towards the full power version.

    Patients on cardiac assist devices are often considered to be high-risk solid organ donors. We report the first case of a reduced size liver transplant performed using the left lateral segment of a pediatric donor whose cardiac function was supported by a Berlin Heart. The recipient was a 22-day-old boy with neonatal hemochromatosis who developed fulminant liver failure shortly after birth. The transplant was complicated by mild delayed graft function, which required delayed biliary reconstruction and abdominal wall closure, as well as a bile leak. However, the graft function improved quickly over the first week and the patient was discharged home with normal liver function 8 weeks after transplant. The presence of a cardiac assist device should not be considered an absolute contraindication for abdominal organ donation. Normal organ procurement procedures may require alteration due to the unusual technical obstacles that are encountered when the donor has a cardiac assist device.

    Berlin relies on induced bank filtration from a broad-scale, lake-type surface water system. Because the hydraulic conductivity of the lake sediments is low, infiltration only occurs close to the more permeable shore zones. Using multiple environmental tracer methods, a strong vertical age stratification of the bank filtrate could be shown. Travel times are generally long and vary throughout the upper aquifers from a few months near the ground surface to several decades in greater depth. Infiltration is mostly anoxic and redox zones were found to be vertically stratified too, becoming more reducing with depth. Because Berlin’s watercourses contain a proportion of treated municipal sewage a number of wastewater residues, e. g. pharmaceutical residues, were detected in surface water and groundwater. While the majority of the pharmaceutical residues studied were efficiently removed during underground passage, some substances (AMDOPH, primidone and carbamazepine) were found to be very persistent.

    The architect Johann Heino Schmieden (1835-1913) in research today is primarily perceived, if perceived at all, as the partner of Martin Gropius (1824-1880), with whom he maintained a joint architectural firm for 15 years. So far, not much has been published about his life and his achievements. The author proves that Schmieden's life's accomplishments deserve better appreciation and that he belonged to the leading representatives of his profession. Citing numerous examples in the Berlin area, the author presents Heino Schmieden as a nationally and internationally sought-after and leading hospital architect, without forgetting to mention that he discusses only one, albeit the most important, aspect of his work in the present article.

    1969-01-01

    An insecticidal exotoxin from Bacillus thuringiensis var. thuringiensis (Berliner) has been purified. The efficiency of each stage of the purification has been ascertained and the yield of toxic material estimated by means of a quantitative bioassay. It is shown that the exotoxin is an adenine derivative substituted at position 9 and having a molecular weight of approximately 825. It can be dephosphorylated enzymically or chemically under conditions that define the exotoxin as a phosphomonoester. This results in loss of toxicity, both to insects and to mice. Spectroscopic and kinetic data are presented which suggest that a β-ribofuranosyl moiety may be attached to the adenine. Glucose and allomucic acid have been positively identified as hydrolysis fragments from the exotoxin. These results are discussed and compared with the results of others on similar (or possibly identical) compounds. PMID:5820635

  2. Crestal unconformities as indicators of clastic stratigraphic traps: genetic relation of Berlin field and Elk City structure, deep Anadarko basin

    SciTech Connect

    Lyday, J.R.

    1988-02-01

    The Berlin fan-delta gas reservoir in the deep Anardarko basin was deposited during the late Atokan (Pennsylvanian) as a response to the initial uplift and erosion of the Elk City structure. During the late Atokan pulse of the episodic Pennsylvanian orogeny in the south-central US, abrupt epeirogenic uplift and brittle deformation created an interregional unconformity on positive areas around foreland and cratonic basins. The Elk City structure within the deep Anadarko basin originated as a distinct, subaerially exposed upthrust-block during the late Atokan tectonic event. A crestal unconformity developed on the emergent upthrust block concurrent with its uplift. Terrigenous, detrital Atoka dolomite, originally sourced from the Arbuckle dolomite (Cambrian-Ordovician) of the Amarillo-Wichita uplift, was eroded from the upthrust block and recycled northward as the Berlin fan-delta. Today, the Berlin recrystallized, recycled detrital dolomite fan-delta is a large 41 mi/sup 2/ overpressured gas reservoir with 242-362 bcf reserves at 15,000 ft. The Berlin field is genetically related to the late Atokan crestal unconformity of the Elk City structure, and is an example of the association of crestal unconformities and clastic stratigraphic traps. Such stratigraphic traps originated in marine environments proximal to active structures that have become subaerially exposed. With adequate seals and favorable structural position, detrital deposits recycled from local uplifts can form significant stratigraphic traps. Such stratigraphic traps can occur in compressional, extensional, and diapiric regions.

  3. Lethal pedestrian--passenger car collisions in Berlin. Changed injury patterns in two different time intervals.

    2009-04-01

    To expand the passive safety of automobiles protecting traffic participants technological innovations were done in the last decades. Objective of our retrospective analysis was to examine if these technical modifications led to a clearly changed pattern of injuries of pedestrians whose death was caused by the accidents. Another reduction concerns the exclusion of injured car passengers--only pedestrians walking or standing at the moment of collision were included. We selected time intervals 1975-1985 and 1991-2004 (=years of construction of the involved passenger cars). The cars were classified depending on their frontal construction in types as presented by Schindler et al. [Schindler V, Kühn M, Weber S, Siegler H, Heinrich T. Verletzungsmechanismen und Wirkabschätzungen der Fahrzegfrontgestaltung bei Pkw-Fussgänger-Kollisionen. Abschlussbericht im Auftrag der Deutschen Versicherungswirtschaft e.V. TU-Berlin Fachgebiet Kraftfahrzeuge (GDV) 2004:36-40]. In both periods more than 90% of all cars were from the usual types small/medium/large class. Hundred and thirty-four autopsy records of such cases from Department of Forensic Medicine (Charité Berlin) data were analysed. The data included technical information of the accidents and vehicles and the external and internal injuries of the victims. The comparison of the two periods showed a decrease of serious head injuries and femoral fractures but an increase of chest-, abdominal and pelvic injuries. This situation could be explained by an increased occurrence of soft-face-constructions and changed front design of modern passenger cars, resulting in a favourable effects concerning head impact to the car during accident. Otherwise the same kinetic energy was transferred to the (complete) victim - but because of a displacement of main focus of impact the pattern of injuries modified (went distally).

  4. Spectral Characterization of Mars Analogues From the Berlin Emissivity Database (BED)

    NASA Astrophysics Data System (ADS)

    2007-12-01

    Several well-recognized Martian soil analogues have been classified and studied in the past years. The JSC Mars-1, collected and distributed under control of the NASA Johnson Space Center, originates from Puú Nene cinder cone in Hawaii, USA. It is a palagonitic tephra (glassy volcanic ash altered at low temperatures), whose spectral features resemble the bright regions on Mars. The Salten Skov, coming from a subsurface deposit in the Midjutland region of Denmark, is a Fe-oxide precipitate with a dark red color, composed mainly of goethite, hematite and maghemite, with mineralogical and magnetic close to those of the martian soil. Montmorillonite and palagonite are other natural materials commonly referred as Martian soil analogues. We present and discuss the emissivity spectra of these analogue minerals from the Berlin Emissivity Database spectral library. The Berlin Emissivity Database (BED) currently contains also emissivity spectra of plagioclase and potassium feldspars, low Ca and high Ca pyroxenes, olivine, elemental sulfur and a lunar highland soil sample measured in the wavelength range from 3 to 50 μm as a function of particle size. For each sample we measured the spectra of four particle size separates ranging from < 25 to 250 μm. The current main setup at the Planetary Emissivity Laboratory (PEL) at DLR consist of an emissivity device built at DLR coupled to a Fourier transform infrared spectrometer (Bruker VERTEX 80v) equipped with both a cooled MTC detector and a room temperature DTGS detector. All spectra were acquired with a spectral resolution of 4 cm- 1. The combination of detectors and spectrometer allows a unique wavelength coverage encompassing the whole thermal radiation range measured by spacecraft instruments. The emissivity device is currently purged with dry air, while the spectrometer is evacuated. In a future upgrade of the facility the emissivity device will be replaced by a planetary simulation chamber which can be evacuated and which

    To determine the planetary surfaces composition, remote sensing infrared spectroscopy is a suitable and powerful method of investigation. Past, present and future missions to bodies in the solar system include in their payload instruments measuring the emerging radiation in the infrared range. The MERTIS instrument, a TIR spectrometer combined with a radiometer, is part of the scientific payload of the ESA BepiColombo mission to Mercury, scheduled for 2013. The Berlin Emissivity Database (BED) is an emissivity spectral library of planetary analogue materials, essential for the interpretation of the measured data. Our unique database is focused on relatively fine-grained size separates, providing a realistic basis for interpretation of thermal emission spectra of Mercury and other planetary bodies. The BED spectral library currently contains emissivity spectra of plagioclase and potassium feldspars, low Ca and high Ca pyroxenes, olivine, elemental sulfur and a lunar highland soil sample measured in the wavelength range from 7 to 22 µm as a function of particle size. For each sample we measured the spectra of four particle size separates ranging from 0 to 250 µm. The device we used is built at DLR (Berlin) and is coupled to a Fourier transform infrared spectrometer (Bruker IFS 88), purged with dry air and equipped with a cooled detector (MCT). All spectra were acquired with a spectral resolution of 4 cm-1 . We present here the emissivity spectra of a basic set of analogue materials reflecting the current knowledge of the surface composition of Mercury. We are currently working to upgrade our emissivity facility: a new spectrometer (Bruker VERTEX 80v) and new detectors will allow us to measure the emissivity of samples in the wavelength range from 1 to 50 µm, even in a vacuum environment.

    Furuncular myiasis is a parasitic infestation of human and other vertebrate tissues by fly larvae of primarily two species: Dermatobia hominis (human botfly, t6rsalo, or berne) in Mexico and South and Central America and Cordylobia anthropophaga (tumbu fly or mango fly) in Africa. Cuterebra species (rabbit and rodent botflies) are also rarely reported to cause furuncular myiasis only within the United States. Although these species inhabit different geographic regions and have different life cycles, their clinical presentations can be similar. We describe a case of "imported" human botfly (D. hominis) furuncular myiasis in a U.S. Army soldier stationed in Germany. We review the life cycles of human botflies and key aspects of their clinical presentation, differential diagnosis, and various therapeutic modalities. Most physicians may never encounter myiasis and attribute a patient's complaints to an insect bite or skin infection that will heal without treatment. However, the diagnosis of furuncular myiasis should be considered by remembering the basic elements of this condition: recent travel history to the tropics and a sterile, persistent furuncle with sensations of movement and pain.

    Purpose The aim of this study was to compare the sensitivity and specificity of two questionnaires to identify patients with obstructive sleep apnea (OSA). Materials and methods Fifty-three moderate to severe OSA patients [with a respiratory disturbance index (RDI)≥15] and 31 controls (RDI<15) based on ambulatory somnographic assessment were recruited through flyers and mail at USC School of Dentistry. Each patient answered the Berlin and apnea risk evaluation system (ARES) questionnaires. The responses to the questionnaires were scored and compared for significant group differences. Results Moderate and severe OSA patients were predominantly male, older, had a larger neck size, and larger body mass index than controls. There were no significant differences in race or ethnicity between the two groups. In this study, subjects having a “high risk” ARES questionnaire were 7.9 times as likely to have OSA as subjects with “low or no risk” score (p=0.0002). The ARES questionnaire had a sensitivity of 90.6%, specificity of 43.2%, a positive predictive value (PPV) of 73.8%, and negative predictive value (NPV) of 73.7% compared to 67.9%, 54.8%, 72%, and 50%, respectively, for the Berlin questionnaire using a cut point of RDI≥15. Conclusions In this specific patient group, not uncommon to the regular dental private practice, the ARES questionnaire performed better than the Berlin questionnaire with higher sensitivity, similar PPV, higher NPV, but lower specificity. The lower specificity could be explained in part because the ARES has been tailored to screen patients with an RDI≥5, and our study included mostly mild to severe patients. In conclusion, in this specific group of subjects, the ARES questionnaire is a better choice than the Berlin questionaire; however, the Berlin questionnaire is publicly available and the ARES screener is proprietary.

    Founded 2011 the TUM Critical Zone Observatory run by the Technische Universität München and partners abroad is the first CZO within Germany. TUM CZO is both, a scientific as well as an education project. It is a watershed based observatory, but moving behind this focus. In fact, two mountainous areas are integrated: (1) The Ammer Catchment area as an alpine and pre alpine research area in the northern limestone Alps and forelands south of Munich; (2) the Otter Creek Catchment in the Bavarian Forest with a crystalline setting (Granite, Gneiss) as a mid mountainous area near Regensburg; and partly the mountainous Bavarian Forest National Park. The Ammer Catchment is a high energy system as well as a sensitive climate system with past glacial elements. The lithology shows mostly carbonates from Tertiary and Mesozoic times (e.g. Flysch). Source-to-sink processes are characteristic for the Ammer Catchment down to the last glacial Ammer Lake as the regional erosion and deposition base. The consideration of distal depositional environments, the integration of upstream and downstream landscape effects are characteristic for the Ammer Catchment as well. Long term datasets exist in many regards. The Otter Creek catchment area is developed in a granitic environment, rich in saprolites. As a mid mountainous catchment the energy system is facing lower stage. Hence, it is ideal comparing both of them. Both TUM CZO Catchments: The selected catchments capture the depositional environment. Both catchment areas include historical impacts and rapid land use change. Crosscutting themes across both sites are inbuilt. Questions of ability to capture such gradients along climosequence, chronosequence, anthroposequence are essential.

    A heterostructured Ag3PO4/AgBr/Ag plasmonic photocatalyst was prepared by a rational in situ ion exchange reaction between Ag3PO4 micro-cubes and Br- in aqueous solution followed by photoreduction. The photocatalytic activities of obtained photocatalysts were measured by the degradation of methyl orange (MO) and methylene blue (MB) under visible light irradiation (λ >= 400 nm). Compared to AgBr/Ag, Ag3PO4/AgBr heterocrystals and pure Ag3PO4 crystals, the heterostructured Ag3PO4/AgBr/Ag plasmonic photocatalysts exhibit much higher photocatalytic activity and stability. This enhanced photocatalytic activity suggests that the synergetic effects of the heterostructured Ag3PO4/AgBr/Ag and the strong SPR of Ag NPs on the surface result in the high efficiencies of the photocatalytic activity and the improved stability. With the assistance of Ag3PO4/AgBr/Ag heterostructures, only 8 min and 12 min are taken to completely decompose MO and MB molecules under visible-light irradiation, respectively. Furthermore, the photodegradation rate does not show an obvious decrease during ten successive cycles, indicating that our heterostructured Ag3PO4/AgBr/Ag plasmonic photocatalysts are extremely stable under visible-light irradiation.A heterostructured Ag3PO4/AgBr/Ag plasmonic photocatalyst was prepared by a rational in situ ion exchange reaction between Ag3PO4 micro-cubes and Br- in aqueous solution followed by photoreduction.

    In some patients with diabetes mellitus (DM) chronic hyperglycemia leads to microvascular complications in retina, kidney and nerves. Concerning missing data from Germany cited prevalence in German educational books and guidelines arise from other countries. This review demonstrates the prevalence of diabetic comorbidities in Germany. The largest investigation in Germany is the Disease-Management-Programm Nordrhein with more than 450.000 surveyed DM  patients. These researches show good comparability with most analyses respective to the prevalence of diabetic comorbidities in Germany. Patients with DM2 have a mean Hba1c of 7 % and patients with DM1 of 7.9 %. In patients with DM2 the prevalence of retinopathy is 11 %, nephropathy 10 % and neuropathy 20 %. Co-morbidities are more commonin patients with long diabetes duration and high HbA1c. In patients with DM1 the prevalence of retinopathy is 25 %, of nephropathy 15 % and neuropathy 27 %. The prevalence of diabetic co-morbidities in primary care in Germany is considerably lower as mentioned in educational books or guidelines. This positive development is reasonable through a better quality of care, nationwide early detection examinations and training programmes.

    The capabilities of the X-ray beamlines at Berliner Elektronenspeicherring für Synchrotronstrahlung II (BESSY II) for hard X-ray measurements with micro- and nanometer spatial resolution are reviewed. The micro-X-ray fluorescence analysis (micro-XRF), micro-extended X-ray absorption fine structure (micro-EXAFS), micro-X-ray absorption near-edge structure (micro-XANES) as well as X-ray standing wave technique (XSW), X-ray beam induced current (XBIC) in combination with micro-XRF and micro-diffraction as powerful methods for organic and inorganic sample characterization with synchrotron radiation are discussed. Mono and polycapillary optical systems were used for fine X-ray focusing down to 1 µm spot size with monochromatic and white synchrotron radiation. Polycapillary based confocal detection was applied for depth-resolved micro-XRF analysis with a volume resolution down to 3.4 · 10 - 6 mm 3. Standing wave excitation in waveguides was also applied to nano-EXAFS measurements with depth resolution on the order of 1 nm. Several examples of the methods and its applications in material research, biological investigations and metal-semiconductor interfaces analysis are given.

    This study reports data on intellectual functioning in old and very old age from the Berlin Aging Study (N = 516; age range = 70-103 years; mean age = 85 years). A psychometric battery of 14 tests was used to assess five cognitive abilities: reasoning, memory, and perceptual speed from the broad fluid-mechanical as well as knowledge and fluency from the broad crystallized-pragmatic domains. Cognitive abilities had a negative linear relationship with age, with more pronounced age-based reductions in fluid-mechanical than crystallized-pragmatic abilities. At the same time, ability intercorrelations formed a highly positive manifold, and did not follow the fluid-crystallized distinction. Interindividual variability was of about equal magnitude across the entire age range studied. There was, however, no evidence for substantial sex differences. As to origins of individual differences, indicators of sensory and sensorimotor functioning were more powerful predictors of intellectual functioning than cultural-biographical variables, and the two sets of predictors were, consistent with theoretical expectations, differentially related to measures of fluid-mechanical (perceptual speed) and crystallized pragmatic (knowledge) functioning. Results, in general indicative of sizeable and general losses with age, are consistent with the view that aging-induced biological influences are a prominent source of individual differences in intellectual functioning in old and very old age. Longitudinal follow-ups are underway to examine the role of cohort effects, selective mortality, and interindividual differences in change trajectories.

  15. Border cases between autonomy and relevance: Economic sciences in Berlin--A natural experiment.

    PubMed

    Düppe, Till

    2015-06-01

    The faculty of economics at today's Humboldt University in Berlin, as no other institution of economics, has witnessed three radical ruptures in its history: in 1933, National Socialism replaced the pluralism prevailing in the Weimar Republic by imposing a "German economics"; after WWII, GDR authorities replaced this NS regime by imposing a Marxist imperative, which after the fall of the wall was replaced by the Western standards of neoclassical economics. In reconstructing these three reforms, institutional history can serve as a context in which questions about the political nature of economic knowledge can be answered that remain speculative in a conceptual context. I thus present a natural experiment in the political epistemology of economics: How do economists respond to, resist, and stabilize, changing political regimes? How do economists renegotiate the autonomy of economic knowledge given changing demands as of its social task? Among others, I show that contrary to Robert Merton's old, but still widely held thesis in political epistemology-that the values of science are compatible only with democratic regimes-the totalitarian and authoritarian regimes created better conditions for methodological pluralism in economics than democratic society.

    The BERLinPro project is a compact, c.w. SRF energy recovery linac (ERL) that is being built to develop the accelerator physics and technology required to operate the next generation of high current ERLs. The machine is designed to produce a 50 MeV 100 mA beam, with better than 1 mm-mrad emittance. The electron source for the ERL will be a SRF photoinjector equipped with a multi-alkali photocathode. In order to produce a SRF photoinjector to operate reliably at this beam current HZB has undertaken a 3 stage photoinjector development program to study the operation of SRF photoinjectors in detail. The 1.4 cell cavity being reported on here is the second stage of this development, and represents the first cavity designed by HZB for use with a high quantum efficiency multi-alkali photocathode. This paper will describe the work done to prepare the cavity for RF testing in the vertical testing dewar at Jefferson Laboratory as well as the results of these RF tests.

    A new central railway station - Lehrter Bahnhof - is being built in Berlin. Because of construction activities in immediate vicinity and because of difficult soil conditions, vertical displacements will be expected. In order to avoid damage to the bridges and to a widely spanned glass roof which will be supported by two concrete bridges these two bridges have to be monitored right from the beginning of construction until commissioning as well as later on for several years. For this purpose, a long-term monitoring concept has been developed. Sensors with excellent long-term stabilty have been chosen to carry out the concept. This paper describes the measuring concept as well as components of the system. Especially techniques to monitor settlements and heaves and to measure strain and inclination of the prestressed concrete bridges are described. All measures are redundantly monitored. Measurements on-site are referenced by measurements on two large-scale beam models well-defined loaded under laboratory and field conditions.

    2016-08-01

    This paper focuses on the diversity in patients' experience of bio-medicine and contrasts it with the normative view characteristic of health professionals. Ethnographic fieldwork among Polish migrant women in London, Barcelona and Berlin included interviews about their experiences with local healthcare and health professionals. Themes drawn from the narratives are differences between the cities in terms of communication between patients and health professionals, respect for patients' choices and dignity, attitudes to pregnancy and birth (different levels of medicalization), and paediatric care. It is argued that patients continuously negotiate among their own views and expectations based on previous experiences and knowledge from personal communication; internet forums and publications; and the offer of medical services in the countries of their settlement. Patients experience pluralism of therapeutic traditions within and outside bio-medicine. In turn, representatives of bio-medicine are rarely aware of other medical practices and beliefs and this leads to various misunderstandings. By highlighting the pluralism of medical practices in European countries and the increasing mobility of patients, this case study has useful implications for medical anthropologists and health professionals in a broader Western context, such as raising sensitivity to different communication strategies and a diversity of curing traditions and expectations.

    In the last decade several IR spectrometers flew on spacecrafts around terrestrial planets (e.g. PFS on MEX and VEX, TES on MGS). In the future years a new generation of IR spectrometers will continue the exploration of the planets in our solar system. The MERcury Thermal infrared Imaging Spectrometer (MERTIS) is a TIR Spectrometer combined with a radiometer instrument covering the range from 7 to 14 μm at a high spectral resolution of up to 90 nm. MERTIS will globally map the planet with a spatial resolution of 500 m and S/N ratio of at least 100. MERTIS will map 5-10% of the surface with a spatial resolution higher than 500 m [1]. A twin of the MERTIS instrument (SERTIS) will flow on the proposed LEO German mission to the Moon. For the interpretation of the remote sensing measured data an emissivity spectral library of planetary analogue materials is needed. The Berlin Emissivity Database (BED) presented here is focused on relatively fine-grained size separates, providing a realistic basis for interpretation of thermal emission spectra of planetary regoliths, and is therefore complimentary to existing thermal emission libraries.

    The 3D flow in a model of the Berlin ventricular assist device (VAD) chamber with monoleaflet valves placed in S-shape conduits was simulated numerically. The blood flow dynamics were described in terms of flow patterns, velocity, pressure, and shear stress. The hemodynamic properties and the VAD's potential risk for thrombosis were evaluated in terms of mixing and washout properties, and global estimations of platelet level of activation (LOA). In order to evaluate the role of valves on the flow in the chamber, the flow in a model with bileaflet valves in straight conduits was simulated and compared with the original case. The results showed that in both models a large rotating flow was developed in the chamber during filling. This vortex filled the entire chamber and moved constantly up to the peak ejection phase, resulting in relatively low shear stress (up to 0.4 Pa) and no lasting stagnation regions. Significant shear stresses were found near the valves with higher values near the outlet valve in both models. The configuration of valves and conduits had a large effect on VAD washout and mixing properties, with advantage to the bileaflet model. However, since the bileaflet valves exhibited higher shear stresses, higher LOA were found for the bileaflet model.

    Options for long-term mechanical circulatory support to sustain pediatric heart failure patients requiring cardiac transplantation while they wait for donor hearts have been unsatisfactory. The conventional approach has been to use extracorporeal membrane oxygenation (ECMO), but its lack of feasibility for long-term use and the major complications associated with the technology have limited its use, especially in light of lengthy waiting lists for donor hearts. With the advent of the Berlin Heart EXCOR® Pediatric ventricular assist device (VAD), pediatric heart failure specialists have gained an important tool for helping this patient population survive until a donor heart can be identified. The EXCOR Pediatric VAD is designed to support pediatric patients of all age groups, from newborns to teenagers, and can be used successfully for many months. This paper describes the early experience with the EXCOR Pediatric VAD and the challenging journey undertaken to gain U.S. FDA approval, including successful completion of the first worldwide prospective clinical study of VADs in a pediatric population.

The findings were brought in relation to the extent of extant tooth malalignment and malocclusion (model analysis according to Eismann). Statistical methods were employed to test existing relationship for significance, allowing for age, sex and former orthodontic treatment. The results were evaluated in view of the need for orthodontic treatment.

    Oestrus synchronisation by means of PGF2 alpha analogues was followed by injection of Gonavet "Berlin-Chemie" which triggered off an LH peak, 2 to 3 hours from injection. Injection of Gonavet "Berlin-Chemie", 44 hours after PGF2 alpha application, caused synchronisation of all LH peaks. The interval between injection of Gonavet "Berlin-Chemie" and onset of ovulation amounted to 22 hours. The length of ovulation was not accurately determinable. Ovulation was successfully induced to all sheep by application of Gonavet "Berlin-Chemie", 44 or 48 hours after PGF2 alpha injection. Ovulation rates were 1.75 or 1.54. Luteolytic action on sheep of Cloprostenol "Jenapharm", a PGF2 alpha analogue, proved to be just as good as that of Oestrophan (SPOFA).

    The paper examines the history of constitutional therapy in Weimar and Nazi Germany. Focusing on Walther Jaensch's “Institute for Constitutional Research” at the Charité in Berlin, it shows how an entrepreneurial scientist successfully negotiated the changing social and political landscape of two very different political regimes and mobilized considerable public and private resources for his projects. During the Weimar period, his work received funding from various state agencies as well as the Rockefeller foundation, because it fit well with contemporary approaches in public hygiene and social medicine that emphasized the need to restore the physical and mental health of children and youths. Jaensch successfully positioned himself as a researcher on the verge of developing new therapies for feeble-minded people, who threatened to become an intolerable burden on the Weimar welfare state. During the Nazi period, he successfully reinvented himself as a racial hygienist by convincing influential medical leaders that his ideas were a valuable complement to the negative eugenics of Nazi bio-politics. “Constitutional therapy,” he claimed, could turn genetically healthy people with “inhibited mental development” (geistigen Entwicklungshemmungen) into fully productive citizens and therefore made a valuable contribution to Nazi performance medicine (Leistungsmedizin) with its emphasis on productivity.

    Repeated loss of fine soil particles by dust emission from arable fields caused by tillage operations, decline soil fertility and reduce air quality. The objective of this study was to quantify the diurnal dynamic of topsoil moisture and the connected PM10-emission of 15 different soils from arable fields around Berlin. As typical for the young moraine landscape in NE Germany, soils from glacial (sand and loam dominated), aeolian (silt loam), and fluvial (organic) sediments were selected. Soil samples were placed outside under hot summer and clear sky conditions for 24 h to reproduce the natural dynamic of soil surface moisture, including dew uptake during the night and evaporation during the day. Dynamic of PM10 emissions of all soils were then measured nine times per day in a stationary wind tunnel. Glacial and fluvial sands showed lowest fine dust emission potential (PM10pot) between 89 and 415 μg PM10 g-1 soil, while PM10pot of loess soils were higher (369-1215 μg PM10 g-1 soil). During the night, the moisture of all samples increased slightly by dew uptake, and fine dust emissions of soil samples were reduced up to 51% directly after sunrise. Highest average reductions in PM10 emissions were found for glacial and fluvial loams. Some hours after sunrise, all soil samples heated up and quickly dried again. Under minimal moisture conditions, highest fine dust emissions were measured between 10 a.m. and 3 p.m.

    The raccoon, Procyon lotor (Carnivora: Procyonidae), is an invasive species that is spreading throughout Europe, in which Germany represents its core area. Here, raccoons mostly live in rural regions, but some urban populations are already established, such as in the city of Kassel, or are starting to build up, such as in Berlin. The objective of this study was to investigate Sarcoptes (Sarcoptiformes: Sarcoptidae) infections in racoons in these two urban areas and to identify the putative origin of the parasite. Parasite morphology, and gross and histopathological examinations of diseased skin tissue were consistent with Sarcoptes scabiei infection. Using nine microsatellite markers, we genotyped individual mites from five raccoons and compared them with Sarcoptes mites derived from fox, wild boar and Northern chamois, originating from Italy and Switzerland. The raccoon-derived mites clustered together with the fox samples and were clearly differentiated from those of the wild boar and chamois samples, which suggests a fox origin for the raccoon mange infection. These results are evidence of the cross-transmission of S. scabiei among wild carnivores. Although our results cannot elucidate whether raccoons became infected by frequent interaction with endemically or epidemically infected foxes or whether these cases resulted from occasional contacts among these animal species, they do nevertheless show that pathogens can be shared among urban populations of native and invasive carnivores.

  8. The Diary of Schiaparelli in Berlin (26 October 1857-10 May 1859): a guide for his future scientific activity

    Tucci, P.

    In February 1857, three years after his degree in Turin, Giovanni Virginio Schiaparelli moved to Berlin with a scholarship from the Sardinian government. There he lived for over two years and from October he attended the University. Berlin was an important astronomical center at the time and the young Schiaparelli had the opportunity to study with some of the most distinguished astronomers of his epoch and to be in one of the best equipped observatory in the world. During his staying in Berlin Schiaparelli regularly wrote a diary which runs from Monday, October 26, 1857 to Tuesday, May 10, 1859. The Diary is very important for the reconstruction of Schiaparelli's training as an astronomer. In this communication I'll give some information about the sections of the Diary which deal more strictly with astronomy. In the Diary all astronomical trainings of the mature Schiaparelli are outlined. But there is an exception: Mars and the inhabitability of other worlds. This rises an intere-sting historiographical problem which pushes historians to find elsewhere the origins of a research which is inextricably linked to Schiaparelli and that allowed him to found the planetology as a new astronomical discipline.

    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.

  10. Provisions for containment venting in Germany

    In this short paper an overlook is given of the systems developed in Germany for filtered containment venting and their implementation in nuclear power plants. More information on the development can be found in the Proceedings of the DOE/NRC Aircleaning Conferences. In Germany, 28.8 % of the electric energy is produced by 19 nuclear power reactors. No new power reactor is expected to be built at least within the next ten years, but France and Germany cooperate in the development of a future European Power Reactor (ERP). This reactor type will be fitted with a core catcher and passive cooling in order to avoid serious consequences of a hypothetical core meltdown accident so that provisions for containment venting are not required. 3 refs., 6 figs., 1 tab.

    A checklist of the German earthworm fauna (Oligochaeta: Lumbricidae) is presented, including published data, data from reports, diploma- and PhD- theses as well as unpublished data from museum collections, research institutions and private persons. Overall, 16,000 datasets were analyzed to produce the first German checklist of Lumbricidae. The checklist comprises 46 earthworm species from 15 genera and provides ecological information, zoogeographical distribution type and information on the species distribution in Germany. Only one species, Lumbricus badensis Michaelsen, 1907, is endemic to Germany, whereas 41% are peregrine. As there are 14 species occurring exclusively in the southern or eastern part of Germany, the species numbers in German regions increase from north to south.

  12. Significant prevalence of sickle cell disease in Southwest Germany: results from a birth cohort study indicate the necessity for newborn screening.

    Children with sickle cell disease (SCD) benefit from newborn screening, because life-threatening complications can be prevented by pre-symptomatic diagnosis. In Germany, the immigration of people from endemic countries is steadily growing. Comprehensive data about the epidemiology and prevalence of SCD in Germany are however lacking, and SCD is not included in the national newborn screening program. We provide data on the prevalence of SCD in a population from both urban and rural areas in Southwest Germany. Anonymized dried blood spots from 37,838 unselected newborns were analyzed by allele-specific PCR for the HbS mutation. Samples tested positive were subjected to Sanger sequencing of the entire β-globin coding sequence firstly to validate the screening and secondly to identify compound heterozygous SCD patients with other mutations of the β-globin gene. We identified 83 carriers of the sickle cell trait, three compound heterozygous SCD patients (two with sickle cell-β-thalassemia, one with sickle cell-Hb Tianshui) but no homozygous SCD patients. The novel molecular method and strategy for newborn screening for SCD presented here compares favorably in terms of sensitivity (1.0 for homozygous HbS, 0.996 for heterozygous HbS), specificity (0.996), practicability, and costs with conventional biochemical screening. Our results demonstrate a significant prevalence of SCD of approximately 1:12,000 in an unselected urban and rural population in Southwest Germany. Together with previously published even higher results from exclusively urban populations in Berlin and Hamburg, our data provide the basis for the decision on a newborn screening program for SCD in Germany.

  13. Has East Germany overtaken West Germany? Recent trends in order-specific fertility.

    2011-01-01

    Some 20 years after reunification, the contrast between East and West Germany offers a natural experiment for studying the degree of persistence of Communist-era family patterns, the effects of economic change, and fertility postponement. After reunification, period fertility rates plummeted in the former East Germany to record low levels. Since the mid-1990s, however, period fertility rates have been rising in East Germany, in contrast to the nearly constant rates seen in the West. By 2008, the TFR of East Germany had overtaken that of the West. We explore why fertility in East Germany is higher than in West Germany, despite unfavorable economic circumstances in the East. We address this and related questions by (a) presenting an account of the persisting East/West differences in attitudes toward and constraints on childbearing, (b) conducting an order-specific fertility analysis of recent fertility trends, and (c) projecting completed fertility for the recent East and west German cohorts. In addition to using the Human Fertility Database, perinatal statistics allow us to calculate a tempo-corrected TFR for East and West Germany.

  16. [Dangerous dogs in Berlin in comparison to the dog population--ways to reduce the dangerousness of dogs].

    PubMed

    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

    Albert Einstein accepted a "special" visiting professorship at the University of Leiden in the Netherlands in February 1920. Although his appointment should have been a mere formality, it took until October of that year before Einstein could occupy his special chair. Why the delay? The explanation involves a case of mistaken identity with Carl Einstein, Dadaist art, and a particular Dutch fear of revolutions. But what revolutions was one afraid of? The story of Einstein's Leiden chair throws new light on the reception of relativity and its creator in the Netherlands and in Germany.

    In the late 1980's, the incidence of invasive fungal diseases (IFDs) in Germany was estimated with 36.000 IFDs per year. The current number of fungal infections (FI) occurring each year in Germany is still not known. In the actual analysis, data on incidence of fungal infections in various patients groups at risk for FI were calculated and mostly estimated from various (mostly national) resources. According to the very heterogenous data resources robust data or statistics could not be obtained but preliminary estimations could be made and compared with data from other areas in the world using a deterministic model that has consistently been applied in many countries by the LIFE program ( www.LIFE-worldwide.org). In 2012, of the 80.52 million population (adults 64.47 million; 41.14 million female, 39.38 million male), 20% are children (0-14 years) and 16% of population are ≥65 years old. Using local data and literature estimates of the incidence or prevalence of fungal infections, about 9.6 million (12%) people in Germany suffer from a fungal infection each year. These figures are dominated (95%) by fungal skin disease and recurrent vulvo-vaginal candidosis. In general, considerable uncertainty surrounds the total numbers because IFDs do not belong to the list of reportable infectious diseases in Germany and most patients were not hospitalised because of the IFD but a distinct underlying disease.

    Research Questions: Are there differences in postpartum contraceptive use between women with and without immigration background? Do women more commonly use contraception following a high-risk pregnancy or caesarean section? What role does current breastfeeding play and, amongst immigrants, what is the effect of acculturation level on the frequency of contraceptive use? Study Population and Methods: Data collection was carried out as part of a larger study in three Berlin delivery units using standardised interviews (questionnaires covering e.g. sociodemographics, immigration history/acculturation and use of antenatal care); telephone interviews comprising 6 questions on postpartum contraception, breastfeeding and postpartum complications were conducted on a sample of the study population six months after delivery. Results: 247 women with, and 358 women without a background of immigration were included in the study (total study population n = 605, response rate 81.1 %). 68 % of 1st generation immigrants, 87 % of 2nd/3rd generation women and 73 % of women without immigration background (non-immigrants) used contraception. In the logistical regression analysis 1st generation immigrants were less likely than non-immigrants to be using contraception six months postpartum, and 1st generation immigrants with low acculturation level were significantly less likely to use contraception than 2nd/3rd generation women with low acculturation level. Conclusion: In the extended postpartum period there was no major difference in contraceptive use between immigrants in general and non-immigrants. It remains unclear whether the differing contraceptive behaviour of 1st generation immigrants is the result of less access to information, sociocultural factors or differing contraceptive requirements and further targeted, qualitative study is required.

  1. Regression analysis of time trends in perinatal mortality in Germany 1980-1993.

    Numerous investigations have been carried out on the possible impact of the Chernobyl accident on the prevalence of anomalies at birth and on perinatal mortality. In many cases the studies were aimed at the detection of differences of pregnancy outcome measurements between regions or time periods. Most authors conclude that there is no evidence of a detrimental physical effect on congenital anomalies or other outcomes of pregnancy following the accident. In this paper, we report on statistical analyses of time trends of perinatal mortality in Germany. Our main intention is to investigate whether perinatal mortality, as reflected in official records, was increased in 1987 as a possible effect of the Chernobyl accident. We show that, in Germany as a whole, there was a significantly elevated perinatal mortality proportion in 1987 as compared to the trend function. The increase is 4.8% (p = 0.0046) of the expected perinatal death proportion for 1987. Even more pronounced levels of 8.2% (p = 0. 0458) and 8.5% (p = 0.0702) may be found in the higher contaminated areas of the former German Democratic Republic (GDR), including West Berlin, and of Bavaria, respectively. To investigate the impact of statistical models on results, we applied three standard regression techniques. The observed significant increase in 1987 is independent of the statistical model used. Stillbirth proportions show essentially the same behavior as perinatal death proportions, but the results for all of Germany are nonsignificant due to the smaller numbers involved. Analysis of the association of stillbirth proportions with the (137)Cs deposition on a district level in Bavaria discloses a significant relationship. Our results are in contrast to those of many analyses of the health consequences of the Chernobyl accident and contradict the present radiobiologic knowledge. As we are dealing with highly aggregated data, other causes or artifacts may explain the observed effects. Hence, the findings

  2. Is Germany a model for managers?

    1992-01-01

    Most American managers have a hard time making sense of Germany. The country has a fraction of the resources and less than one-third the population of the United States. Labor costs are substantially higher, paid vacations are at least three times as long, and strong unions are deeply involved at all levels of business, from the local plant to the corporate boardroom. Yet German companies manage to produce internationally competitive products in key manufacturing sectors, making Germany the greatest competitive threat to the United States after Japan. The seemingly paradoxical nature of the German economy typically evokes one of two diametrically opposed responses. The first is to celebrate the German economy as a "model" worth emulating--indeed, as the answer to declining U.S. competitiveness. The alternative, more skeptical response is to question Germany's staying power in a new, more competitive global economy. According to Kirsten Wever and Christopher Allen, the problem with both points of view is that they miss the forest for the trees. Observers are so preoccupied with praising--or blaming--individual components of the German economy that they fail to see the dynamic logic that ties these components together into a coherent system. In their review of recent research on the German business system, Wever and Allen argue that managers can learn an important lesson from Germany. In the global economy, competition isn't just between companies but between entire socioeconomic systems. Germany's ability to design a cohesive economic and social system that adapts continuously to changing requirements goes a long way toward explaining that country's competitive success.

  5. Bismuth selenides from St. Andreasberg, Germany: an oxidised five-element style of mineralisation and its relation to post-Variscan vein-type deposits of central Europe

    2016-12-01

    Carbonate veinlets at Roter Bär, a former underground mine in the polymetallic St. Andreasberg vein district of the Harz Mountains, Germany, host selenide minerals that are characterised as Bi-Ag-bearing clausthalite (PbSe), tiemannite (HgSe), guanajuatite (Bi2Se3) and a number of selenides of Bi, Zn, Cu, Ag and Pd. An unnamed Bi-Pb-Ag selenide species with some Hg and Cu, ideally Bi4Pb3Ag2Se10, is reported here. Specular hematite is disseminated within the clausthalite, at the marginal zones of which other selenide minerals are located. The occurrence of bohdanowiczite (AgBiSe2) and umangite (Cu3Se2) constrains the formation temperature to ≤120 °C, and the selenide-hematite assemblage (plus barite in the carbonate gangue) identifies highly oxidised conditions. Selenide assemblages of Pb, Bi, Ag, with and without Co and Ni, occur in many parts of the Variscan basement of central Europe (Harz, Erzgebirge, Schwarzwald and Bohemian Massif) and represent a high-oxidation variety of five-element (Ag-As-Bi-Co-Ni) veins.

    Objective: To investigate the population of bipolar patients in a general hospital in Germany who required treatment by a consultant psychiatrist. Method: A retrospective analysis was conducted of the clinical records of 47 patients diagnosed with bipolar disorder (DSM-IV-TR criteria) who were treated by a consultant psychiatrist between 2009 and 2012 in one of the general hospitals of Charité Berlin, Campus Benjamin Franklin, Berlin, Germany. We investigated the sections of the hospital that requested psychiatric consultations for bipolar patients, the status of these patients, and their primary cause of treatment, as well as the intervention (including pharmacotherapy) recommended by the consultant psychiatrist. Results: For more than half of the patients, their psychiatric illness was either directly or indirectly the reason they presented to the hospital. The remaining bipolar patients were treated for various somatic illnesses unrelated to their bipolar disorder throughout the hospital, with a relative overrepresentation of patients in the neurology department. More than half of the patients were referred to a psychiatric hospital by the consultant psychiatrist. Benzodiazepines were the most commonly administered drugs for acute pharmacologic intervention. Conclusions: Psychiatric consultations are not frequently requested for bipolar patients compared to those with other psychiatric disorders. However, more than half of the bipolar patients needed further psychiatric treatment in a psychiatric hospital. This finding emphasizes the importance of psychiatric consultations in a general hospital for bipolar patients. The administration of benzodiazepines as an acute treatment seems to be the standard pharmacologic procedure, not a specific pharmacotherapy like mood stabilizers. PMID:25133062

    Introduction Mucopolysaccharidosis VI (MPS VI) is an inherited lysosomal storage disease caused by a mutation of the gene for arylsulfatase B (ASB). Of the thirty-one patients registered in Germany, almost fifty percent have a Turkish migration background. MPS VI is treated by enzyme replacement therapy (ERT), which is time-consuming and expensive. Methods This interdisciplinary study explored the illness perceptions and clinical treatment experiences among ten MPS VI patients with a Turkish migration background in two centers for metabolic diseases (Berlin and Mainz, Germany). The clinical treatment situation was observed and semi-structured interviews were conducted with patients and health care personnel, in addition to participatory observation in four patients' everyday environments in Berlin. The data from the interviews, patient records, and personal field notes were encoded, cross-related, and analyzed. Results Patients' acknowledgement of the disease and coping strategies are influenced predominantly by the perception of their individual health status and the handling of the disease within their family. Patients' willingness to cooperate with treatment strategies is further modified by their knowledge of the disease and the relationships with their health care providers. In this analysis, cultural factors turned out to be marginally relevant. Conclusion As with other chronic and debilitating diseases, effective treatment strategies have to reach beyond delivering medication. Health care providers need to strengthen the support for patients with a migration background. In this regard, they should respect the patients' cultural and social background and their personal perception of the disease and the therapy. Yet structural and social aspects (clinical setting, family and educational background) may be more crucial here than “cultural barriers.” PMID:23826140

  8. Preparation and antibacterial activities of Ag/Ag+/Ag3+ nanoparticle composites made by pomegranate (Punica granatum) rind extract

    Yang, Hui; Ren, Yan-yu; Wang, Tao; Wang, Chuang

    Nano-silver and its composite materials are widely used in medicine, food and other industries due to their strong conductivity, size effect and other special performances. So far, more microbial researches have been applied, but a plant method is rarely reported. In order to open up a new way to prepare AgNP composites, pomegranate peel extract was used in this work to reduce Ag+ to prepare Ag/Ag+/Ag3+ nanoparticle composites. UV-Vis was employed to detect and track the reduction of Ag+ and the forming process of AgNPs. The composition, structure and size of the crystal were analyzed by XRD and TEM. Results showed that, under mild conditions, pomegranate peel extract reacted with dilute AgNO3 solution to produce Ag/Ag+/Ag3+ nanoparticle composites. At pH = 8 and 10 mmol/L of AgNO3 concentration, the size of the achieved composites ranged between 15 and 35 nm with spherical shapes and good crystallinity. The bactericidal experiment indicated that the prepared Ag/Ag+/Ag3+ nanoparticles had strong antibacterial activity against gram positive bacteria and gram negative bacteria. FTIR analysis revealed that biological macromolecules with groups of sbnd NH2, sbnd OH, and others were distributed on the surface of the newly synthesized Ag/Ag+/Ag3+ nanoparticles. This provided a useful clue to further study the AgNP biosynthesis mechanism.

    Starting from the fundaments set by Rolf Wideroe and Max Steenbeck, the first medical betatron was developed by Konrad Gund at the Siemens centre in Erlangen. This was the first highly sophisticated, large-scale technical device in medicine. Over a period of 30 years Siemens has manufactured a total of 137 betatrons with different maximum energies and sold them worldwide to scientific institutes and radiotherapy departments, among them the most prestigious therapy centres in Germany and Europe. Methodological investigations on high energy electrons und ultrahard X-rays have paved the way for the establishment of the modern high-energy radiation therapy. The interdisciplinary and increasingly more biophysics-oriented research on and with betatrons has had a decisive influence on the establishment of the profession of the medical physicist.

    Against the background of demographic change, mobility issues are becoming crucial. Especially for the elderly, daily outdoor activities are essential for participation in social life. This article addresses the question of what extent older people, especially women, are threatened by limited social participation in Berlin's suburbia. The mobility of older women (70+) is characterized by the least number of trips, the shortest distances, and more than 50% walking trips. Besides, many older women are dissatisfied with their residential area. Given the lack of essential facilities, older women have to be considered as disadvantaged in terms of limited social participation.

    Ebola virus disease (EVD) outbreaks have occurred during the past 5 decades, but none has affected European countries like the 2014 epidemic in West Africa. We used an online questionnaire to investigate risk perceptions in Germany during this epidemic peak. Our questionnaire covered risk perceptions, knowledge about transmission routes, media use, reactions to the outbreak, attitudes toward measures to prevent the spread of EVD and vaccination against EVD, and willingness to volunteer for aid missions. Of 974 participants, 29% indicated that they worried about EVD, 4% correctly stated virus transmission routes, and 75% incorrectly rated airborne transmission and transmission by asymptomatic patients as possible. Many indicated that if a patient were flown to Germany for treatment in a nearby hospital, they would adapt preventive behavior. Although most participants were not worried about EVD at the current stage of the epidemic, misperceptions regarding transmission were common and could trigger inappropriate behavior changes.

    In November 2005, an outbreak of tularemia occurred among 39 participants in a hare hunt in Hesse, Germany. Previously reported tularemia outbreaks in Germany dated back to the 1950s. We conducted a retrospective cohort study among participants and investigated the environment to identify risk factors for infection. Ten participants had serologic evidence of acute Francisella tularensis infection; 1 other participant died before laboratory confirmation was obtained. Presence within 5 meters of the place where disemboweled hares were rinsed with a water hose was the risk factor most strongly associated with infection (risk ratio 22.1; 95% confidence interval 13.2-154.3). Swabs taken at the game chamber and water samples were PCR negative for F. tularensis. Eleven of 14 hare parts showed low-level concentrations of F. tularensis, compatible with cross-contamination. More than half of case-patients may have acquired infection through inhalation of aerosolized droplets containing F. tularensis generated during rinsing of infected hares.

    Engstrom, Eric J

    2014-01-01

    This article examines the topography and "cultural machinery" of forensic jurisdictions in Imperial Germany. It locates the sites at which boundary disputes between psychiatric and legal professionals arose and explores the strategies and practices that governed the division of expert labor between them. It argues that the over-determined paradigms of 'medicalization' and 'biologization' have lost much of their explanatory force and that historians need to refocus their attention on the institutional and administrative configuration of forensic practices in Germany. After first sketching the statutory context of those practices, the article explores how contentious jurisdictional negotiations pitted various administrative, financial, public security, and scientific interests against one another. The article also assesses the contested status of psychiatric expertise in the courtroom, as well as post-graduate forensic psychiatric training courses and joint professional organizations, which drew the two professional communities closer together and mediated their jurisdictional disputes.

    Larvae, pupae and eggs of the Asian tiger mosquito Aedes albopictus were found in Freiburg, southern Germany, after submission of an adult mosquito specimen from that area to the 'Mückenatlas', a German instrument of passive mosquito surveillance. While previously collected Ae. albopictus in Germany were trapped on, or close to, service stations on motorways, suggesting introduction by vehicles from southern Europe, these new specimens were out of flight distance from the motorway on the one hand and indicate local reproduction on the other. The findings call for a thorough active and passive surveillance in exposed geographic regions such as the relatively warm German Upper Rhine Valley to prevent Ae. albopictus from establishing.

    A combined strategy of in situ oxidation and assembly is developed to prepare Ag/AgCl nanospheres and nanocubes from Ag nanoparticles under room temperature. It is a new facile way to fabricate Ag/AgCl with small sizes and defined morphologies. Ag/AgCl nanospheres with an average size of 80 nm were achieved without any surfactants, while Ag/AgCl nanocubes with a mean edge length of 150 nm were obtained by introduction of N-dodecyl- N, N-dimethyl-2-ammonio-acetate. The possible formation mechanism involves the self-assembly of AgCl nanoparticles, Ostwald ripening and photoreduction of Ag+ into Ag0 by the room light. The as-prepared Ag/AgCl nanospheres and nanocubes exhibit excellent photocatalytic activity and stability toward degradation of organic pollutants under visible-light irradiation. It is demonstrated that Ag/AgCl nanocubes display enhanced photocatalytic activity in comparison with Ag/AgCl nanospheres due to the more efficient charge transfer. This work may pave an avenue to construct various functional materials via the assembly strategy using nanoparticles as versatile building blocks.

    We have utilized conditions of very low temperature (4.7 K) and very low sulfur coverage to isolate and identify Ag-S complexes that exist on the Ag(111) surface. The experimental conditions are such that the complexes form at temperatures above the temperature of observation. These complexes can be regarded as polymeric chains of varying length, with an Ag4S pyramid at the core of each monomeric unit. Steps may catalyze the formation of the chains and this mechanism may be reflected in the chain length distribution.

    Traditionally the strongman of Europe, Germany's chemical sector had a miserable time in 1992, as profits skidded 30%. Further declines in production and sales for the first half of 1993 are predicted by industry association VCI (Frankfurt). Output, usually spurred after the summer break, dropped drastically in the fourth quarter. Developments are alarming, says Wolfgang Hilger, president of the VCI and chairman of Hoechst (Frankfurt). Production in the 11 western states rose 1% in 1992, but chemical industry sales fell. In the second half of the year, the high value of the Germany mark - against the US dollar, sterling, lira, and peseta - compounded difficulties already experienced as a result of overcapacity and lower prices. Hilger says overall prices declined 2% last year. Meanwhile, costs for labor and environmental protection continued to increase. VCI figures show a decline in many sectors. In western Germany, organic base chemical production was down 4%, and, while organic chemical production rose 3%, prices were 8% lower, giving unsatisfactory results. Similarly, plastics production was up 0.5% at midyear, but weak prices hurt earnings.

    2016-12-01

    In November 2012, 23 cases of ciguatera with typical combinations of gastrointestinal and neurological symptoms occurred in Germany after consumption of imported tropical fish (Lutjanus spp.). A questionnaire was used to gather information on the disease course and fish consumption. All patients suffered from pathognomonic cold allodynia. Aside from two severe courses of illness, all other cases showed symptoms of moderate intensity. During a three-year follow-up, seven patients reported prolonged paresthesia for more than one year. Two of them reported further neuropathies over almost three years. This is the first time that long-term persistence of symptoms has been documented in detail. Outbreak cases were allocated to eight clusters in seven German cities. A further cluster was prevented by the successful recall of ciguatoxic fish. Three clusters were confirmed by the detection of ciguatoxin in samples of suspicious and recalled fish. An extrapolation on the basis of ciguatoxic samples revealed twenty prevented cases of ciguatera. Further officially unknown cases should be assumed. During the outbreak investigations, inadvertently falsely labelled fish species and fishing capture areas on import and retail level documents were observed. The ascertainment of cases and the outbreak investigations proved to be difficult due to inconsistent case reports to poisons centers, local health and veterinary authorities. In Germany, many physicians are unaware of the disease pattern of ciguatera and the risks caused by tropical fish. The occurrence of further outbreaks during the following years emphasizes the increasing significance of ciguatera in Germany.

    2015-10-01

    Telemedicine as a subject has reached politics, doctors and patients, but it has still not been able to make the leap from research, development, and testing into real practice. This is generally because of the great barriers to implementation, mainly the lack of telematics infrastructure and of payment regulations in Germany. Telemedicine projects are mainly isolated applications and it has not been possible to integrate them in to nationwide regular health services. Other challenges along the path to standard care include that research-based small-medium enterprise (SME) companies usually face high barriers hindering access to this market, because it is imposible for them to finance all the required evidence-based studies to verify the medical benefits and the econimic efficiency. Additionally, a high market nontransparency is noted. However, the signs of progress are visible, e.g., the E-health initiative of the German government or recent legislative initiatives. However, long processes are observed that do not facilitate the use of telemedicine. Although some federal states, e.g., North Rhine Westphalia, Bavaria, Mecklenburg-Western Pomerania, and Saxony, show exemplary activities, there are still many white areas on the telemedicine map of Germany. The road to standard care will be long, but is not unattainable. The reasons for supporting telemedicine are still strong. The future development of telemedicine applications will contribute to sustainable and high-quality patient care in Germany.

    Runci, PJ

    1999-11-01

    Germany's total national (i.e., combined public and private sector) funding for R&D stood at $42 billion in 1997. The private sector accounted for nearly 62% ($24 billion) of the total, while the public sector accounted for approximately 38%. Since the late 1970s, when the public and private sectors each funded roughly half of Germany's R&D, the private sector has steadily assumed a larger and larger role as the dominant supporter of R&D activity, while overall government funding has remained essentially flat for much of the past two decades. In addition to declining relative to private R&D expenditures, public R&D expenditures in Germany declined by 4% in real terms between 1991 and 1997, to approximately $15 billion. The reduction in R&D investments in the public sector can be attributed in large part to the financial challenges associated with German reunification and related shifts in social priorities including efforts to address high unemployment and to rebuild basic infrastructure in the eastern states. R&D expenditures have also declined as a percentage of the total public budget, from a peak of 3.4% in 1985 to 2.7% in 1996. Energy R&D has been the hardest hit of all major socioeconomic areas of R&D expenditure funded by the German government. Between 1981 and 1997, public energy R&D fell from approximately $1.6 billion to $400 million--a 75% real decline. The $850 million reduction in Germany's fission R&D budget (which constituted two-thirds of government R&D investment in 1985) explains some 90% of the funding decline. Negative public perceptions regarding the safety and environmental impacts of nuclear energy have reduced nuclear power's viability as a long-term energy option for Germany. Discussions of a complete nuclear phaseout are now under way. At the same time, the German government has slashed its investments in fossil energy R&D by more than 90%. While energy efficiency and renewable energy technologies have fared relatively well in comparison

    Starting from an assessment of how far Robert Koch's bacteriology had developed in the late 1880s this paper attempts to analyse different aspects of the process that led to the foundation of the Berlin Institute for Infectious Diseases in 1891. With the development of his supposed cure against tuberculosis, tuberculin, Koch attempted to give his research a new direction, earn a fortune with the profits and become more independent of Prussian government officials who, up to that point, had had a major influence on his career. In the period following the presentation of the cure in autumn 1890, however, it became clear that tuberculin's value in treatment was at most dubious. Thus, the failure of tuberculin meant that Koch had to drop his own plans and accommodate those of the Prussian Ministry of Culture. As a result he assumed directorship of the newly founded Institute for Infectious Diseases in Berlin. Even though this was definitely a prestigious position it reaffirmed Koch's dependency on Prussian government officials and was by no means the kind of institution he had aimed for at the outset.

    The Berlins Porphyry located on the South Island of New Zealand provides an opportunity to examine iron concretions formed in a subterranean system. Specifically, an alteration zone within the Berlins Porphyry contains iron concretions similar to sedimentary biologically-mediated iron concretions. Here, we provide evidence for two sources of dissolved Fe (II) that potentially aided in the formation of the iron concretions. Furthermore, we discuss the potential for microbial involvement in the anaerobic oxidation of Fe (II) to Fe (III) to form magnetite. Evidence in support of this hypothesis includes the low concentrations of iron and sulfur in the white hydrothermally altered porphyry outcrop and concretion cores; concentrated pyrite and magnetite mineralisation surrounding the cores; and δ13C values indicative of organic carbon (averaging -26 ‰ ± 4 ‰) within the iron cement, porphyry-core-boundary and outer weathered rinds of the concretions. Overall, these unusually preserved iron concretions could represent a new environmental niche for microorganisms and a potential analogue for microbially induced iron-oxidation. More importantly, this study illustrates the many obstacles involved in analysing and interpreting potential subterranean biosignatures.

    The Berlin Climate Middle Atmosphere model (CMAM) with resolution T21 and lid at 84km (Langematz and Pawson, 1997) has been interactively coupled with the chemistry module of Steil et al., (1998). Chemical tracer fields from a test run which used the Palmer gravity wave drag (GWD) scheme have been found to compare well both with observations and other models (e.g. MA-ECHAM4-CHEM). However, in this run the model pole has a warm bias and dynamical variability is not well reproduced. Therefore we are currently testing a suite of orographic and non-orographic GWD schemes in the model. Preliminary results from these latter runs are presented here and focus on stratospheric and mesospheric chemical processes during polar winter, particularly those affecting ozone. The contrast between hemispheres, the springtime 'recovery' of polar stratospheric ozone and relevant chemical diurnal cycles are explored. Bibliography U.

    Plasmonic Ag2MoO4/AgBr/Ag composite is fabricated by in-situ ion exchange and reduction methods at room temperature. The samples are characterized by X-ray diffraction (XRD), UV-vis diffuse reflectance (DRS), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscope (SEM) and photoluminescence (PL) measurements. The results show that butterfly-like Ag2MoO4 nanosheets served as the precursor, and Ag2MoO4/AgBr/Ag is formed in phase transformation with MoO42- displaced by Br-. The ternary Ag2MoO4/AgBr/Ag composite photocatalysts show greatly enhanced photocatalytic activity in photodegrading methylene blue (MB) under visible light irradiation compared with AgBr and Ag2MoO4. The pseudo-first-order rate constant kapp of Ag2MoO4/AgBr/Ag is 0.602 min-1, which is 11.6 and 18.3 times as high as that of AgBr and Ag2MoO4, respectively. Meanwhile, the efficiency of degradation still kept 90% after ten times cyclic experiments. Eventually, possible photocatalytic mechanism was proposed.

    On the occasion of his retirement from the position as head of the Jewish Hospital in Berlin in 1917, the famous kidney surgeon James Israel (1848-1926) was portrayed by Max Liebermann (1847-1935). At that time both men were leading members of their professions--medicine and fine arts--and represented the Jewish community in Berlin. Private contacts between the surgeon and the artist had been established when Liebermann and his wife needed surgical treatment themselves some years before. Liebermann's later friendship with the surgeon Ferdinand Sauerbruch (1875-1951) culminated in one of the best-known portraits of a member of the medical profession. This biographical article from the history of medicine and fine arts reflecting the relation of these men provides a special view of the development of urological surgery in Berlin at the beginning of the twentieth century.

    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. AgH, Ag/sub 2/, and AgO revisited: Basis set extensions

    1987-05-01

    An extended basis set has been developed for Ag which significantly improves the agreement between theoretical and experimental spectroscopic parameters for AgH, AgO, and Ag/sub 2/. The major improvement comes about as a result of the improved treatment of electron correlation in the Ag d shell upon the introduction of f functions. Their inclusion produces very slight differences at the SCF level, but significant reductions in r/sub e/ and increases in ..omega../sub e/ and D/sub e/ in the Mo-dash-barller--Plesset perturbation theory expansion. At the MP4(SDTQ) level, typical results are 0.02 A too long for r/sub e/, 4% too low for ..omega../sub e/, and 10 kcal too small for D/sub e/. From a pragmatic standpoint, MP2 give results very similar to this at a much reduced level of effort.

    The previous slow beam extraction electro static septum in the AGS was designed in 1981. Research documented at the Fermi Laboratory was used as the base line for this design. The septum consisted of a ground plane of .002 inch diameter wire tungsten-rhenium alloy (75%W 25%Re) with a hollow welded titanium cathode assembly. The vacuum chamber is stationary and the septum is moved with a pair of high vacuum linear feed throughs. After years of beam time, the frequency of failures increased. The vacuum system design was poor by today's standards and resulted in long pump down times after repairs. The failures ranged from broken septum wires to a twisted cathode. In addition to the failures, the mechanical drive system had too much backlash, making the operating position difficult to repeat. The new septum needed to address all of these issues in order to become a more reliable septum.

    The AGS Booster has three objectives. They are to increase the space charge limit of the AGS, to increase the intensity of the polarized proton beam by accumulating many linac pulses (since the intensity is limited by the polarized ion source), and to reaccelerate heavy ions from the BNL Tandem Van de Graaff before injection into the AGS. The machine is capable of accelerating protons at 7.5 Hertz from 200 MeV to 1.5 GeV or to lower final energies at faster repetition rates. The machine will also be able to accelerate heavy ions from as low as 1 MeV/nucleon to a magnetic rigidity as high as 17.6 Tesla-meters with a one second repetition rate. As an accumulator for polarized protons, the Booster should be able to store the protons at 200 MeV for several seconds. We expect that the Booster will increase the AGS proton intensity by a factor of four, polarized proton intensity by a factor of twenty to thirty, and will also enable the AGS to accelerate all species of heavy ions (at present the AGS heavy ion program is limited to the elements lighter than sulfur because it can only accelerate fully stripped ions). The construction project started in FY 1985 and is expected to be completed in 1989. The purpose of this paper is to provide a future reference for the AGS Booster lattice.

    Deutsche Texaco A.G. will be the first operator on behalf of itself and Wintershall A.G. to produce oil from the German sector of the North Sea, with its first oil due end of 1986 from the Mittelplate pilot project. Texaco also was the first to produce oil from the Baltic Sea when Schwedeneck-See field, near Kiel Bay, went on production last year. The pilot project at Mittelplate will yield more data on the reservoirs confirmed by four wells drilled in 1980-1981, and will be carried out in spite of adverse operating conditions. Problems facing Texaco engineers in their project design include: A mud-flat location dry at low tide but submerged at high tide. Efforts to convince environmental groups that no permanent harm would result from company activities. Shipment of low-gravity crude containing asphaltenes. Logistics of transporting equipment and supplies on a schedule dictated by tides.

    In 1998 there were only twelve Jewish veterinarians known who practised in Germany between 1918 and 1945. 133 of them have now been found. Most of the Jewish veterinarians had their roots in merchant families and were general practitioners in the countryside. To be "Jewish" did not concern until 1933. Compared with the other medical professionals like human medical professionals (10,9 %), in 1933 the number of Jewish veterinarians was low (1,6 %, whole German Jewish population 0,77 %). Right with the beginning of the National Socialistic rule Jewish veterinarians were exposed to different forms of harassment. Soon after, on April 7th 1933, with the so-called Gesetz zur Wiederherstellung des Berufsbeamtentums (BBG; law for the restoration of civil service), the prosecution took on an official quality. The Reichstierärztekammer (Chamber of veterinary service) was very eager to Aryanize the German veterinary service. The BBG made the Jewish veterinarians who worked in public positions lose their jobs with the single exception of those who had the status of a so-called "Frontkämpfer" (a soldier who fought at the frontline during World War I). Many of the Jewish veterinarians who were still in Germany in November 1938 were arrested after the pogrom of November 9/10th and kept in concentration camps and prisons for about one month. The few students of veterinary medicine who already had started their studies in 1933 still could make their exams in Germany, but they did not get a licence. On January 31st 1939 all Jewish veterinarians in Germany lost their licence. 55 Jewish vets managed to emigrate in time. Nineteen German Jewish Veterinarians died in concentration camps and ghettos. Two are known to have committed suicide. Until 1997, there was no act of appreciation or rehabilitation of German Jewish veterinarians. In 2003 the degrees of two Jewish veterinarians, Hermann Cussel and Paul Stern, were renewed posthumously by the Hanover School of Veterinary Medicine

    We report luminance measurements of the summer night sky at a field site on a freshwater lake in northeastern Germany (Lake Stechlin) to evaluate the amount of artificial skyglow from nearby and distant towns in the context of a planned study on light pollution. The site is located about 70 km north of Berlin in a rural area possibly belonging to one of the darkest regions in Germany. Continuous monitoring of the zenith sky luminance between June and September 2015 was conducted utilizing a Sky Quality Meter. With this device, typical values for clear nights in the range of 21.5-21.7 magSQM/arcsec2 were measured, which is on the order of the natural sky brightness during starry nights. On overcast nights, values down to 22.84 magSQM/arcsec2 were obtained, which is about one third as bright as on clear nights. The luminance measured on clear nights as well as the darkening with the presence of clouds indicates that there is very little influence of artificial skyglow on the zenith sky brightness at this location. Furthermore, fish-eye lens sky imaging luminance photometry was performed with a digital single-lens reflex camera on a clear night in the absence of moonlight. The photographs unravel several distant towns as possible sources of light pollution on the horizon. However, the low level of artificial skyglow makes the field site at Lake Stechlin an excellent location to study the effects of skyglow on a lake ecosystem in a controlled fashion.

  4. Health care reform and Diagnosis Related Groups in Germany: The mediating role of Hospital Liaison Committees for Jehovah's Witnesses.

    2016-10-01

    Resulting from health care reform in Germany that was implemented in 2003-2004, a new medical classification system called the "Diagnosis Related Groups" (DRGs) was introduced in hospitals. According to the media, social scientists, and a few physicians interviewed in this study the policy negatively transformed the German health care system by allowing the privatization of the hospital sector consistent with the neoliberal health care model. Allegedly, this privileged economic values over the quality of health care and introduced competition between hospitals. Nevertheless, members of the Hospital Liaison Committees (HLCs) of Jehovah's Witnesses argued that the DRGs system could be used to the advantage of Jehovah's Witness (JW) patients. HLCs often assist in the patient's search by providing names of physicians that would be willing to refrain from blood transfusions. This article draws from nine months of ethnographic research with Jehovah's Witnesses, including members of the HLCs, carried out primarily in Berlin between 2010 and 2012. By focusing on JWs, whose refusal of blood transfusions is often exemplified as particularly difficult for the biomedical profession, it addresses the "unintended" consequences of the introduction of DRGs into the German health care system that remain unexplored by health and social science scholarship. It argues that although JWs have long been associated with the judicialization of religious freedom globally, they do not equally engage in the judicialization of health in countries such as Germany. The reason for this is embedded not only in health care policy that favors mediation over medical malpractice litigation. It also results from the synergy of health care reforms that prioritize standardizing and economizing measures such as DRGs as well as practices implemented by Patient Blood Management programs that JW institutions, such as HLCs, have tapped into.

    The author of this essay, Hermann Alexander Brück, Emeritus Professor of Astronomy at the University of Edinburgh and former Astronomer Royal for Scotland, died on 4 March 2000 in his 95th year. He was the last of his generation of astronomers in both Germany and Britain, and among the oldest members, if not the oldest, of the Royal Astronomical Society and of the Astronomische Gesellschaft. Hermann Brück was born in Berlin in 1905 and, as he recounts below, received his education at the Universities of Kiel, Bonn and Munich in 1924-1928. To the end of his life he looked back on his student days in Munich as the most profitable and exciting he ever experienced. From Munich he began his astronomical career at the Potsdam Astrophysical Observatory. These, too, were happy days, destined, however, to be blighted within a few years by the rise of Nazism. In 1936 Brück left Germany, and obtained a temporary Research Assistantship at the Vatican Observatory. From there he went a year later to Cambridge, rising to the rank of John Couch Adams Astronomer and Assistant Director of the Observatory. In 1947, in response to an invitation from Eamon de Valera, then Taoiseach (Prime Minister) of Ireland, he moved to Dublin where he undertook the task of re-founding the defunct Dunsink Observatory under the auspices of the Dublin Institute for Advanced Studies. He moved from Dublin to the Royal Observatory Edinburgh in 1957, taking up the combined post of Astronomer Royal for Scotland and Regius Professor of Astronomy in the University of Edinburgh. He retired in 1975 at the age of 70. Always interested in history, he occupied himself in his retirement with various historical projects. These included writing the histories of the Royal Observatory Edinburgh (The Story of Astronomy in Edinburgh, Edinburgh 1983) and of the earlier Dun Echt Observatory in Aberdeenshire (Lord Crawford's Observatory at Dun Echt 1872-1892, Vistas in Astronomy 35, 1992) as well as a record of his own

    By the end of 1995 in total 3655 wind turbines (WT`s) were installed in Germany with a total capacity of 1,136 MW. In the year 1995 alone the WT installations grew by 1,070 units with 505 MW. About 40% of the 1995 installations were sold to inland states of Germany with their lower wind speed potential. This fast development occurred in parallel to continuously reduced local state and federal subsidies. The further development is based mainly on the guaranteed reimbursement due to the Electricity Feed Law. But since some time the electricity utilities fight back on all legal and political levels to get cancelled the unloved Electricity Feed Law and since two years the building construction law with the foreseen privilege for WT`s is discussed without any result. All these difficulties affect investors and credit giving banks in such a negative way, that the further annual increase in wind power installation for 1996 could be 10 to 20% less than in 1995. Many of the new commercial Megawatt WT`s have pitch control and variable rotor speed which cause better electrical power quality and lower life time loads. From statistical evaluations on technical data of WT`s a good overview of the further development is derived. 8 refs., 10 figs.

    A widespread finding among studies from the US and the UK is that maternal employment is correlated with an increased risk of child overweight, even in a causal manner, whereas studies from other countries obtain less conclusive results. As evidence for Germany is still scarce, the purpose of this study is to identify the effect of maternal employment on childhood overweight in Germany using two sets of representative micro data. We further explore potential underlying mechanisms that might explain this relationship. In order to address the selection into maternal full-time employment, we use an instrumental variable strategy exploiting the number of younger siblings in the household as an instrument. While the OLS models suggest that maternal full-time employment is related to a 5 percentage point higher probability of the child to be overweight, IV estimates indicate a 25 percentage points higher overweight probability due to maternal full-time employment. Exploring various possible pathways, we find that maternal full-time employment promotes unhealthy dietary and activity behavior which might explain the positive effect of maternal employment on child overweight to some extent. Although there are limitations to our IV approach, several sensitivity analyses confirm the robustness of our findings.

    In this review I describe the development of environmental medicine as a specialized field of clinical medicine in Germany. New scientific societies were founded, based on traditions of public hygiene and occupational medicine, as a reaction to environmental issues concerning human health. Environmental medicine issues were also addressed by independent "critical" physicians. The first institutions to accept patients were centers for environmental medicine affiliated with research institutions and/or with the public health service. Medical professional organizations, particularly the German General Medical Council, described the need for and formulated conditions for additional qualification for doctors in environmental medicine, including a 200-hr course. This course and a qualifying exam were passed by about 3,000 doctors, mainly from the public health service and from occupational medicine. Unfortunately, few general physicians in primary outpatient care were similarly trained. To date, no representative study has been conducted on environmental patients, but I include in this review a typical list of patients' complaints. I also summarize research activities typical for environmental medicine in Germany. Present problems concern accounting systems and, for example, diagnosis and treatment of patients with multiple chemical sensitivities (MCS). A coordinated research program on MCS has been started.

    Since 1990 the percentage of smokers among the 12 to 17-year-olds in Germany has risen from 21 % to about 28 %. Most of them start between the age of 11 and 13. 85 % favour a certain brand by the age of 18. Despite the prohibition of tobacco commercials on radio and TV the cigarette industry has continually increased their budget for advertising aimed more and more at women and children. According to the author's knowledge, this report describes for the first time the strategies most frequently applied in Germany to incite children and teenagers to smoking. The publicity campaigns are not restricted to billboards and the printed press, but use the internet also. Indirect conditioning to a certain brand by music videos, movies and merchandising of attractive clothes and trips as well as the sponsoring of special music and sports events are also shown.The report analyses and evaluates examples of messages in printed advertisements aimed at children. With psychological skill interest in smoking is created with teenagers and a conditioning for smoking in certain situations is promoted.

    The paper examines the deterioration in German-American relations. The reasons for this downturn in German-American relations are quite simple. Washington views the Persian Gulf crisis as a defining moment in European-American relations and in the creation of a new world order. It is also the first diplomatic test of a unified Germany and a new German-American relationship. It is a test that Germany is thus far seen as having failed for three reasons. First, from the outset many Americans sensed that Germans did not comprehend what this crisis meant for the United States. A second and, in many ways, more worrying factor was the growing sense that the Germans were not being good Europeans. The third and most serious American concern, however, was the unsettling appearance of a very selective German definition of collective defense and common security. The result has been a crisis of confidence in the performance of the German political elite that goes beyond the problems in German-American relations during the early 1980s and the INF debate.

    Streptococcus (S.) castoreus was isolated from seven beavers (Castor fiber), which were found dead in the federal state of Brandenburg, Germany, and submitted to the Berlin-Brandenburg State laboratory for post mortem diagnostics. The isolates originated from various inflammatory processes where they were associated with other Gram negative and Gram positive aerobic and/or anaerobic bacteria (i. e. Actinobacillus sp., species of the Actinomycetaceae family, coliform bacteria, Fusobacterium sp., Prevotella sp.), but also from cloacal swabs. Testing their antimicrobial susceptibility, all S. castoreus isolates and the type strain S. castoreus (DSM 17536) were classified as being susceptible to penicillin G, ampicillin, amoxicillin-clavulanic acid, 1st generation cephalosporins, erythromycin, tetracycline, and chloramphenicole but intermediate to gentamicin. Considering both the polymicrobial flora isolated from the inflamed tissues and the fact that antimicrobials of a narrow spectrum (namely penicillins, 1st generation cephalosporins, macrolids and lincosamids) can be toxic to rodents, chloramphenicol might be a suitable drug for treatment of beavers suffering from S. castoreus (mixed)-bacterial infections.

    The invention of the laser in 1960 and the innovation process of laser technology during the following years coincided with the dramatic increase of the East-West-conflict during the 1960s - the peak of the so-called Cold War after the erection of the Berlin Wall in 1961. The predictable features of the new device, not only for experimental sciences, but also for technical and military applications, led instantly to a laser hype all over the world. Military funding and research played a major part in this development. Especially in the United States military laser research and development played an important role in the formation of Cold War sciences. The European allies followed this example to a certain degree, but their specific national environments led to quite different solutions and results. This article describes and analyzes the special features and background of this development for the Federal Republic of Germany in the area of conflict between science, politics and industry from 1960 to the early 1970s.

    To preserve proton polarization through acceleration, it is important to have a correct model of the process. It has been known that with the insertion of the two helical partial Siberian snakes in the Alternating Gradient Synchrotron (AGS), the MAD model of AGS can not deal with a field map with offset orbit. The stepwise ray-tracing code Zgoubi provides a tool to represent the real electromagnetic fields in the modeling of the optics and spin dynamics for the AGS. Numerical experiments of resonance crossing, including spin dynamics in presence of the snakes and Q-jump, have been performed in AGS lattice models, using Zgoubi. This contribution reports on various results so obtained.

    This study documents age trends, interrelations, and correlates of intellectual abilities in old and very old age (70-103 years) from the Berlin Aging Study (N = 516). Fourteen tests were used to assess 5 abilities: reasoning, memory, and perceptual speed from the mechanic (broad fluid) domain and knowledge and fluency from the pragmatic (broad crystallized) domain. Intellectual abilities had negative linear age relations, with more pronounced age reductions in mechanic than in pragmatic abilities. Interrelations among intellectual abilities were highly positive and did not follow the mechanic-pragmatic distinction. Sociobiographical indicators were less closely linked to intellectual functioning than sensory-sensorimotor variables, which predicted 59% of the total reliable variance in general intelligence. Results suggest that aging-induced biological factors are a prominent source of individual differences in intelligence in old and very old age.

  20. Down syndrome clusters in Germany after the Chernobyl accident

    1997-03-01

    In two independent studies using different approaches and covering West Berlin and Bavaria, respectively, highly significant temporal clusters of Down syndrome were found. Both sharp increases occurred in areas receiving relatively low Chernobyl fallout and concomitant radiation exposures. Only for the Berlin cluster was fallout present at the time of the affected meiosis, whereas the Nuremberg cluster preceded the radioactive contamination by 1 month. Hypotheses on possible causal relationships are compared. Radiation from the Chernobyl accident is an unlikely factor, because the associated cumulative dose was so low in comparison with natural background. Microdosimetric considerations would indicate that fewer than 1 in 200 oocyte nuclei would have experienced an ionizing event from Chernobyl radioactivity. Given the lack of understanding of what causes Down syndrome, other than factors associated with increased maternal age, additional research into environmental and infectious risk factors is warranted. 23 refs., 4 figs., 2 tabs.

  1. Facile synthesis, structure, and properties of Ag2S/Ag heteronanostructure

    NASA Astrophysics Data System (ADS)

    Sadovnikov, S. I.; Gusev, A. I.

    2016-09-01

    Ag2S/Ag heteronanostructure has been produced by a simple one-stage chemical deposition from aqueous solutions of silver nitrate, sodium sulfide, and sodium citrate with the use of monochromatic light irradiation. For simultaneous synthesis of Ag2S and Ag nanoparticles, deposition has been performed from reaction mixtures with reduced sodium sulfide concentration. The size of Ag2S and Ag nanoparticles is 45-50 and 15-20 nm, respectively. It is established that in the contact layer between silver sulfide and silver, nonconducting α-Ag2S acanthite transforms into superionic β-Ag2S argentite under the action of external electric field. The scheme of the operation of a resistive switch based on an Ag2S/Ag heteronanostructure is proposed. The UV-Vis optical absorption spectra of colloidal solutions of Ag2S/Ag heteronanostructures have been studied.

    Ag-deposited TiO2 and Ag (Ag-TiO2/Ag) films coated on glass substrates were prepared using a simple sol-gel and dip-coating method. The Ag chemical state was investigated through X-ray diffractometry and X-ray photoelectron spectroscopy. Results showed that the Ag mainly exists in metallic state in the Ag-TiO2 film. Ag-TiO2/Ag exhibits higher photocatalytic activity than individual Ag-TiO2 and TiO2/Ag films. This enhanced photocatalytic activity was attributed to high surface plasmon resonance effects and separation rates of photoinduced electron-hole pairs of Ag nanoparticles. Results were verified by photoluminescence and UV-Vis spectroscopy.

    There is a need for quick and reliable methods for rapid screening of drug-influenced drivers on the roadside by police. Because the window of detection in oral fluid is more similar to blood than to urine, this matrix should therefore be appropriate for screening procedures. The performance of the Rapid STAT(®) (Mavand Solution GmbH, Mössingen, Germany), DrugWipe5/5+(®) (Securetec Detektions-Systeme AG, Brunnthal, Germany) and Dräger DrugTest(®) 5000 (Draeger Safety AG & Co. KGaA, Luebeck, Germany) on-site oral fluid devices was evaluated with random oral fluid specimens from car drivers in North Rhine-Westphalia (Germany). Additionally, some drivers were checked using an on-site urine device (DrugScreen(®), NAL von Minden, Regensburg, Germany). During a 11-month period, 1.212 drivers were tested. Both OF and urine on-site tests were compared to serum results. The following sensitivities were obtained by the oral fluid devices: THC 71% (DrugWipe(®)), 87% (Dräger), 91% (RapidSTAT); opiates 95% (Dräger), 100% (DrugWipe(®), RapidSTAT(®)); amphetamine 84% (DrugTest(®) 5000), 90% (RapidSTAT(®)), 100% (DrugTest(®) 5000); methamphetamine 50% (DrugTest(®) 5000), 100% (RapidSTAT(®)); cocaine 76% (DrugTest(®) 5000), 100% (DrugWipe(®), RapidSTAT(®)); methadone 33-63%, and benzodiazepines 0-33% (both with a low number of positives). THC specificity was especially low (29% [DrugWipe(®)] and 47% [DrugTest(®) 5000]) due to low cut-off concentrations. These data were similar to those obtained from the literature (e.g., DRUID project). The urine screening device showed a good sensitivity (THC 93%, opiate 94%, amphetamine 94%, methamphetamine 75% (low number of positives), cocaine 100%) and also an acceptable specificity (39%, 86%, 63%, 77%, 47%, respectively). Although oral fluid may be a useful matrix for on-site testing of drugged drivers, it is evident that oral fluid devices still show a lack of sensitivity (methamphetamine, benzodiazepines) and

    1992-01-01

    The transport of oxygen through high-purity membranes of Ag (110), Ag (poly), Ag (nano), and Ag 2.0 Zr has been studied by an ultrahigh vacuum permeation method over the temperature range of 400-800 C. The data show that there are substantial deviations from ordinary diffusion-controlled transport. A surface limitation has been confirmed by glow-discharge studies where the upstream O2 supply has been partially converted to atoms, which, for the same temperature and pressure, gave rise to over an order of magnitude increase in transport flux. Further, the addition of 2.0 wt percent Zr to the Ag has provided increased dissociative adsorption rates, which, in turn, increased the transport flux by a factor of 2. It was also observed that below a temperature of 630 C, the diffusivity exhibits an increase in activation energy of over 4 kcal/mol, which has been attributed to trapping of the atomic oxygen and/or kinetic barriers at the surface and subsurface of the vacuum interface. Above 630 C, the activation barrier decreases to the accepted value of about 11 kcal/mol for Ag (poly), consistent with zero concentration at the vacuum interface.

    Hyalomma rufipes, a two-host tick, is the most widespread Hyalomma species in Africa. In December 2015, an ixodid tick male with an unusual morphology was detected on a horse in a stable near Mainz in the Federal State Rhineland-Palatine. For identification purposes, the tick was preserved in alcohol and sent to our laboratory. The morphology of the tick showed specific characteristics of H. rufipes. The 16S rDNA sequence of H. rufipes from Germany was identical to the corresponding 16S rDNA sequence of H. rufipes from Tanzania, and they both were closely related to Hyalomma marginatum. The tick was tested with a real-time PCR for rickettsiae and Crimean-Congo hemorrhagic fever (CCHF) virus with negative results.

    At least 5 million patients with chronic and severely debilitating pain exist among the adult population in Germany, i.e. 8% of this population. Various biological and psychosocial risk factors contribute to the continuing chronicity of pain, resulting in enormous direct and indirect costs totalling an estimated 38 billion euro annually. The introduction of a medical specialty for pain treatment in 1998 has not appreciably affected the quality of outpatient pain management. In contrast, more recent approaches of multimodal treatment, including medical, psychological and behavioral components, have shown a significant and lasting effect in patients with a high incidence of workplace incapacitation and sick leave. In particular, the GRIP pilot project (Göttingen Intensive Back Project) has resulted in an increased rate (to 200%) of return to the workplace and in a decrease in health system expenses to 50% of the pretreatment level.

  5. Estimating the prevalence of nonpaternity in Germany.

    2012-06-01

    The prevalence of nonpaternity in human societies is difficult to establish. To obtain a current and fairly unbiased estimate of the nonpaternity rate in Germany, we analysed a dataset consisting of 971 children and their parents in whom human leukocyte antigen (HLA) typing had been carried out in the context of bone marrow transplantation. In this sample, nine exclusions (0.93%) could be identified on the basis of more than 300 HLA-haplotypes defined by four HLA genes. Given this number of exclusions, a maximum likelihood estimate of the nonpaternity rate in the population of 0.94% was obtained with asymptotic 95% confidence limits of 0.33% and 1.55%, respectively. This result is in accordance with recent surveys as well as findings from Switzerland for a comparable sample, and it suggests that earlier estimates of the nonpaternity rate which were often in excess of 10% may have been largely exaggerated.

  6. Ejecta of the Ries Crater, Germany

    1982-01-01

    Attention is given to the light which may be shed by the ejecta surrounding the 26-km diameter Ries Crater in West Germany on the Cretaceous-Tertiary Boundary Event. Moldavites represent early high speed ejecta originating at the projectile-target interface. Bunte breccia reflects the major excavation and ejection phase, comprising more than 90 percent of all ejecta beyond the rim crest. Suevite is deposited last, and is derived from the deepest target stratum. Using various scaling laws that relate the bolide's kinetic energy to crater geometry or volume, and assuming a 25 km/sec impact velocity, a 1-2 km projectile diameter is obtained for a stony object. Geochemical studies reveal that projectile dissemination is heterogeneous, and that maximum extraterrestrial contamination modeled as a C1 chondrite is 0.004 wt pct. Observations from this and other terrestrial craters show that tektites and microtectites provide the sole evidence for widespread impact deposits.

    The often fragile relationship between Dow Europe and eastern Germany strengthened this week with an agreement to build a feedstock pipeline from the Baltic Sea to the Buna BSL petrochemical complex at Boehlen. Dow recently agreed to go ahead with its 80% investment in the BSL venture following fears it might withdraw from the project because of European Commission cuts in the amount of state aid available. The multi-feedstock liquid pipeline is expected to transport naphtha, crude oil, and, possibly, liquid petroleum gas from Rostock on the Baltic to the Boehlen site. Besides Dow, the participants are BSL Olefinverbund and Elf subsidiary Mider. Dow is expected to contribute DM450 million toward the investment.

    Child Soldiers as Refugees in Germany How do former child soldiers cope with their potentially traumatic experiences, and how do the living conditions as refugees influence these coping processes? A dissertation at the faculty of human and social sciences at the University of Wuppertal, based on biographical-narrative interviews with 15 young refugees from six African countries, describes the characteristics of the traumatic sequences in the countries of origin and in exile, and elaborates typical coping processes. In order to survive a situation of absolute subjection within armed groups, children develop forms of adequate adaptation to the context like regulation and detachment of emotions e.g. with the use of drugs, assimilation to an idea of "hard masculinity" etc. They become victims, witnesses and often perpetrators of extreme violence (man-made-disaster), respectively traumatic processes can be seen in all sequences. After leaving the armed groups there is no way back into the families and communities destroyed by armed conflict, so they become refugees. In Germany, they are subjected to a bureaucratic and excluding asylum system, in which decisions on all relevant areas of life (age determination, place and right of residence, form of accommodation, access to education, etc.) are imposed on them. Especially the insecure right of residence and the living conditions in refugee camps are severe risk factors, impeding stabilization. Social support, e. g. by competent professionals, access to trauma- and culture-sensitive psychotherapy, societal inclusion, but also personal resilience are essential for coping with trauma and developing new future perspectives.

  9. River habitat monitoring and assessment in Germany.

    Kamp, Ulrich; Binder, Walter; Hölzl, Konrad

    2007-04-01

    Whereas assessing the biological and chemical quality of water is a standard environmental procedure in many countries, the use of habitat survey methods that assess the ecomorphological quality of rivers is relatively new. In Europe, the EC Water Framework Directive requires such assessment from all EU Member States. In Germany, the first river habitat assessments were introduced in the late 1990 s. Each federal state develops its own river habitat map using the 'On-site Survey' and/or the 'Overview Survey'. The assessment describes the difference of the actual condition from a previously defined reference condition. In practice, a defined 'potential for restoration', a more realistic condition, makes restoration activities much easier and more successful. In Germany, the first River Habitat Map 2001 was published in 2002. The survey covered 33,000 km of river length, which equates to 10% of all rivers. A wide range from 'Undisturbed' (class 1) to 'Totally Disturbed' (class 7) river units exists; 77% of them are 'Clearly Disturbed' (class 4) or in worse condition. These result reflects extensive anthropogenic impact on the environment in general, but also past intense technical river 'improvements' that focused on the protection of settlements and traffic routes from flooding, better shipping conditions, the use of water power, and drainage of floodplains for agriculture and urban development. For comparability of survey results between EU Member States, a harmonization of national survey methods is in progress. A crucial point here is the definition of the reference condition for each river (near-natural conditions), since it influences the survey results.

    2010-01-01

    Background Several disease specific registers are operated by members of the ‘TMF – Technology, Methods, and Infrastructure for Networked Medical Research’, an umbrella organization of research networks in Germany. Objective To describe the coverage and the current state as well as financial and organizational issues of registers operated by member networks of the TMF, to identify their requirements and needs, and to recommend best practice models. Methods A survey with a self-completion questionnaire including all 55 TMF member networks was carried out in winter 2007/2008. Interviews focusing on technological issues were conducted and analyzed in summer 2009 with a convenience sample of 10 registers. Results From 55 TMF member networks, 11 provided information about 14 registers. Six registers address diseases of the circulatory system with more than 150,000 registered patients. The interviews revealed a typical setting of “research registers”. Research registers are an important mean to generate hypotheses for clinical research, to identify eligible patients, and to share data with clinical trials. Concerning technical solutions, we found a remarkable heterogeneity. The analysis of the most efficient registers revealed a structure with five levels as best practice model of register management: executive, operations, IT-management, software, hardware. Conclusion In the last ten years, the TMF member networks established disease specific registers in Germany mainly to support clinical research. The heterogeneity of organizational and technical solutions as well as deficits in register planning motivated the development of respective recommendations. The TMF will continue to assist the registers in quality improvement. PMID:23616850

    Although socioeconomic inequalities in cancer survival have been demonstrated both within and between countries, evidence on the variation of the inequalities over time past diagnosis is sparse. Furthermore, no comprehensive analysis of socioeconomic differences in cancer survival in Germany has been conducted. Therefore, we analyzed variations in cancer survival for patients diagnosed with one of the 25 most common cancer sites in 1997-2006 in ten population-based cancer registries in Germany (covering 32 million inhabitants). Patients were assigned a socioeconomic status according to the district of residence at diagnosis. Period analysis was used to derive 3-month, 5-year and conditional 1-year and 5-year age-standardized relative survival for 2002-2006 for each deprivation quintile in Germany. Relative survival of patients living in the most deprived district was compared to survival of patients living in all other districts by model-based period analysis. For 21 of 25 cancer sites, 5-year relative survival was lower in the most deprived districts than in all other districts combined. The median relative excess risk of death over the 25 cancer sites decreased from 1.24 in the first 3 months to 1.16 in the following 9 months to 1.08 in the following 4 years. Inequalities persisted after adjustment for stage. These major regional socioeconomic inequalities indicate a potential for improving cancer care and survival in Germany. Studies on individual-level patient data with access to treatment information should be conducted to examine the reasons for these socioeconomic inequalities in cancer survival in more detail.

    This dissertation records the historical paths of Chinese physicists educated in Germany and America, explores their representative achievements in modern physics that have not been recognized by Chinese scholars, and provides sociological analyses of their contributions to China's higher education. We have found that Chinese students of physics in Germany and America were not passive recipients of Western science, but active contributors. They were also crucial contributors to science education and important scientific projects upon their return to China. Chapter One briefly describes physics knowledge in ancient China and introduces the transplantation of modern science and technology to China. Three distinct historical periods have been identified. In Chapter Two and Chapter Three, 30 Chinese physicists educated in Germany and 89 in America have been investigated. This research analyzes the significant achievements of these physicists. It also examines the political changes, the social background, and other factors impacting on their studies in the two countries. The selected cases in the two chapters are Li Fo-ki, Chinese physics students in Berlin, Werner Heisenberg and his Chinese students, Max Born and his Chinese students, Robert Millikan and Chinese physicists, the first two Chinese physicists from Harvard, and the Science Society of China. Chapter Four explores the geographical distribution, education and careers, return and expatriation, and the social influence exerted by these Chinese physicists. Statistical compilation and quantitative analyses comprise the basic methodology. In terms of two periods and two generations, this dissertation explores the physicists' contributions to the development of modern science in China and to education in China. Significant cases from Beijing University, Qinghua University, and Yanjing University are analyzed. The last chapter, Chapter Five, concludes that some of the achievements of these Chinese physicists were

    Au-Ag alloy nanostructures with various shapes were synthesized using a successive reduction method in this study. By means of galvanic replacement, twined Ag nanoparticles (NPs) and single-crystalline Ag nanowires (NWs) were adopted as templates, respectively, and alloyed with the same amount of Au(+) ions. High angle annular dark field-scanning TEM (HAADF-STEM) images observed from different rotation angles confirm that Ag NPs turned into AuAg alloy rings with an Au/Ag ratio of 1. The shifts of surface plasmon resonance and chemical composition reveal the evolution of the alloy ring formation. On the other hand, single-crystalline Ag NWs became Ag@AuAg core-shell wires instead of hollow nanostructure through a process of galvanic replacement. It is proposed that in addition to the ratio of Ag templates and Au ion additives, the twin boundaries of the Ag templates were the dominating factor causing hollow alloy nanostructures.

  14. Probing the rupture of a Ag atomic junction in a Ag-Au mixed electrode

    We probed that the atomic junction in Ag part ruptures during stretching of atomic sized contacts of Ag-Au mixed electrodes, resulting in Ag-Ag electrodes through a scanning tunneling microscope breaking junction (STM-BJ) technique. We observed that the conductance and tunneling decay constant for a series of amine-terminated oligophenyl molecular junctions are essentially the same for the Ag-Au mixed and the Ag-Ag electrodes. We also found the molecular plateau length and the evolution patterns with the Ag-Au mixed electrodes are similar to those with Ag-Ag electrodes rather than the Au-Au electrodes in the molecular junction elongation. This result is attributed to the smaller binding energy of Ag atoms compared to that of Au atoms, so the Ag junction part is more easily broken than that of Au part in stretching of Ag-Au mixed electrodes. Furthermore, we successfully observed that the rupture force of the atomic junction for the Ag-Au mixed electrodes was identical to that for the Ag-Ag electrodes and smaller than that for the Au-Au electrodes. This study may advance the understanding of the electrical and the mechanical properties in molecular devices with Ag and Au electrodes in future.

    Symbiotic system AG Draconis regularly undergoes quiescent and active stages which consist of the series of individual outbursts. The period analysis of new and historical photometric data, as well as radial velocities, confirmed the presence of the two periods. The longer one (~550 d) is related to the orbital motion and the shorter one (~355 d) could be due to pulsation of the cool component of AG Dra. In addition, the active stages change distinctively, but the outbursts are repeated with periods from 359 - 375 d.

    The Deutscher Olympische Sportbund (DOSB) founded recently an advisory board for German elite athlete nutrition, the 'Arbeitsgruppe (AG) Ernahrungsberatung an den Olympiastutzpunkten'. The 'Performance codex and quality criteria for the food supply in facilities of German elite sports' have been established since 1997. The biochemical equivalent (ATP) for the energy demand is calculated using the DLW (Double Labeled Water)-method on the basis of RMR (Resting Metabolic Rate) and BMR (Basic Metabolic Rate) at sport type specific exercises and performances. Certain nutraceutical ingredients for dietary supplements can be recommended. However, quality criteria for nutrition, cooking and food supply are defined on the basis of Health Food and the individual physiological/social-psychological status of the athlete. Especially food supplements and instant food have to be avoided for young athletes. The German advisory board for elite athlete nutrition publishes 'colour lists' for highly recommended (green), acceptable (yellow), and less recommended (red) food stuff.

    Within the framework of a national mosquito monitoring programme, a mosquito specimen collected in mid-2015 in southern Germany was identified as Aedes koreicus, a non-endemic species originating from East Asia. After the Asian bush mosquito Aedes japonicus, which is already established in Germany and widely distributed, and the Asian tiger mosquito Aedes albopictus, which is increasingly often introduced from southern Europe, A. koreicus is the third demonstrated invasive mosquito species in Germany supposed to have significant vector potential for disease agents.

Palladium is strongly enriched in the metal phases, and sulphide (troilite) is the primary sink for radiogenic silver. Closure of the system hence depends primarily on the transfer of Ag-107 from metal to troilite. Because cation diffusion in troilite is extremely rapid, Ag-107 transfer is likely to be controlled by diffusion through the metal. Sugiura and Hoshino (2003) estimated a closure temperature of ~1100 K for the Pd/Ag system in iron meteorites under the assumption that the diffusion rate of Ag in the metal is similar to that of Ni diffusion in taenite. Here we consider the problem in more detail, utilizing constraints on Ag diffusion in taenite and kamacite from the metallurgical literature to numerically model diffusive exchange between metal and troilite with simultaneous radiogenic ingrowth. The process is complicated by exsolution of the metal into bcc kamacite and fcc taenite phases during cooling. We will discuss approaches to the treatment of this issue and their influence on the derived closure temperatures. Sugiura N., Hoshino H. (2003) Meteorit. Planet. Sci. 38, 117-143.

  1. Ag nanotubes and Ag/AgCl electrodes in nanoporous membranes.

    2011-04-15

    Miniaturization of the entire experimental setup is a key requirement for widespread application of nanodevices. For nanopore biosensing, integrating electrodes onto the nanopore membrane and controlling the pore length is important for reducing the complexity and improving the sensitivity of the system. Here we present a method to achieve these goals, which relies on electroless plating to produce Ag nanotubes in track-etched polymer nanopore templates. By plating from one side only, we create a conductive nanotube that does not span the full length of the pore, and thus can act as a nanoelectrode located inside the nanopore. To give optimal electrochemical behavior for sensing, we coat the Ag nanotube with a layer of AgCl. We characterize the behavior of this nanoelectrode by measuring its current-voltage response and find that, in most cases, the response is asymmetric. The plated nanopores have initial diameters between 100 and 300 nm, thus a range suitable for detection of viruses.

    The photocatalytic performance of ZnO rods in degradation of Rhodamine B dye under UV light was improved by 7.3% via deposition of Ag/AgO using 1.0 × 10-3 g mL-1 of silver nitrate solution. However, its photodegradation efficiency decreased with the increase in silver nitrate concentration which was used to prepare the Ag/AgO-ZnO rods. This result suggests that the loading of Ag/AgO on the surface of ZnO rods affected the photocatalytic performance differently. The scavenger study indicates that the main reactive species responsible for the degradation of Rhodamine B dye by Ag-/AgO-deposited ZnO rods were holes, followed by superoxide anion free radicals, hydroxyl free radicals and electrons. Based on these findings, a refined photodegradation mechanism of Rhodamine B by Ag/AgO-ZnO rods is proposed.

    Amphisbaenia is a speciose clade of fossorial lizards characterized by a snake-like body and a strongly reinforced skull adapted for head-first burrowing. The evolutionary origins of amphisbaenians are controversial, with molecular data uniting them with lacertids, a clade of Old World terrestrial lizards, whereas morphology supports a grouping with snakes and other limbless squamates. Reports of fossil stem amphisbaenians have been falsified, and no fossils have previously tested these competing phylogenetic hypotheses or shed light on ancestral amphisbaenian ecology. Here we report the discovery of a new lacertid-like lizard from the Eocene Messel locality of Germany that provides the first morphological evidence for lacertid-amphisbaenian monophyly on the basis of a reinforced, akinetic skull roof and braincase, supporting the view that body elongation and limblessness in amphisbaenians and snakes evolved independently. Morphometric analysis of body shape and ecology in squamates indicates that the postcranial anatomy of the new taxon is most consistent with opportunistically burrowing habits, which in combination with cranial reinforcement indicates that head-first burrowing evolved before body elongation and may have been a crucial first step in the evolution of amphisbaenian fossoriality.

    Over the last ten years changes in the legal framework of the German health care system have promoted the development of new health service models to improve chronic care. Recent innovations include the nation-wide introduction of disease management programmes (DMPs), integrated care contracts, community nurse programmes, the introduction of General Practitioner (GP)-centred care contracts, and new opportunities to offer interdisciplinary outpatient care in polyclinics. The aim of this article is to describe the recent developments regarding both the implementation of new health care models by statutory health insurance companies and their evaluation. As part of a European project on the development and validation of disease management evaluation methods (DISMEVAL), we carried out a selective literature search to identify relevant models and evaluation studies. However, on the basis of the currently available evaluation and study results it is difficult to judge whether these developments have actually led to an improvement in the quality of chronic care in Germany. Only for DMPs, evaluation is legally mandatory; its methods are inappropriate, though, for studying the effectiveness of DMPs. Further study results on the effectiveness of DMPs mostly focus on the DMP Diabetes mellitus type II and show consistent improvements regarding process parameters such as regular routine examinations, adherence to treatment guidelines, and quality of life. More research will be needed to determine whether DMPs can also help reduce the incidence of secondary disease and mortality in the long term.

    Traumatic experiences resulting from war and violence can lead to a broad spectrum of psychological and somatic stress responses. The psychological strain of traumatized refugees is frequently aggravated by specific post-migration stressors. The current healthcare provision in Germany is characterized by many restrictions. The different residence permits are associated with a limited access to medical and psychotherapeutic services. In addition, there are several barriers limiting access of this group of patients to the healthcare system (e. g. low level of training of mental healthcare staff, language barriers and lack of financing for interpreters). Empirical studies have shown that traumatized refugees profit from existing trauma-focused and evidence-based interventions. Treatment is associated with particular challenges and issues (e. g. use of interpreters, migration and culture-specific as well as legal aspects). Specialized treatment centers for traumatized refugees use a multidisciplinary treatment approach, which includes psychotherapeutic, medical and social work interventions as well as assistance with the residential status and integration programs.

    Though international trade is increasing, the significance of imported reptiles as carriers of pathogens with relevance to animal and human health is largely unknown. Reptiles imported to Germany were therefore investigated for blood parasites using light microscopy, and the detected parasites were morphologically characterized. Four hundred ten reptiles belonging to 17 species originating from 11 Asian, South American and African countries were included. Parasites were detected in 117 (29%) of individual reptiles and in 12 species. Haemococcidea (Haemogregarina, Hepatozoon, Schellackia) were found in 84% of snakes (Python regius, Corallus caninus), 20% of lizards (Acanthocercus atricollis, Agama agama, Kinyongia fischeri, Gekko gecko) and 50% of turtles (Pelusios castaneus). Infections with Hematozoea (Plasmodium, Sauroplasma) were detected in 14% of lizards (Acanthocercus atricollis, Agama agama, Agama mwanzae, K. fischeri, Furcifer pardalis, Xenagama batillifera, Acanthosaura capra, Physignathus cocincinus), while those with Kinetoplastea (Trypanosoma) were found in 9% of snakes (Python regius, Corallus caninus) and 25 % of lizards (K. fischeri, Acanthosaura capra, G. gecko). Nematoda including filarial larvae parasitized in 10% of lizards (Agama agama, Agama mwanzae, K. fischeri, Fu. pardalis, Physignathus cocincinus). Light microscopy mostly allowed diagnosis of the parasites' genus, while species identification was not possible because of limited morphological characteristics available for parasitic developmental stages. The investigation revealed a high percentage of imported reptiles being carriers of parasites while possible vectors and pathogenicity are largely unknown so far. The spreading of haemoparasites thus represents an incalculable risk for pet reptiles, native herpetofauna and even human beings.

  8. Early retirement and mortality in Germany.

    Differences in mortality by retirement age have an important impact on the financing of pension insurance, yet no clear-cut results for Germany exist so far. We calculate mortality rates by retirement age from microdata on all German old-age pensioners and 1.84 million deceases. The life expectancies and survival probabilities at age 65 are estimated for population subgroups according to creditable periods because of disease and pension income. Early-retired men who reach the age of 65 years live significantly longer the later early retirement occurs; the life expectancy at age 65 ranges from 13 to 17.8 years. For each retirement age, mortality of men is higher the more periods of disease are credited in the pension insurance system. For a given length of credited periods of disease, mortality of early retirees decreases with the retirement age. 'Healthy worker selection effects' operating in the labour market may contribute to these results. The 'work longer, live longer'-result is found for each pension income quintile, which resolves the J-curve pattern found in the literature. The mortality of female old-age pensioners varies little with retirement age.

    The status of women in physics in Germany has not changed dramatically in the three years since the last IUPAP Women in Physics Conference was held in 2005. The salary of a woman remains approximately 25% lower than that of a man in a comparable professional position. The number of female professors is growing slowly. The number of young women beginning to study physics is around 20%. There is, however, a noticeable increase in organization and societal acceptance of female physicists, and an increasing amount of men taking part in this process. There is also increased acceptance and support of dual-career couples. The Helmholtz Alliance for "Physics at the Terascale" founded a dual-career option program. In 2008, the annual Conference of German Female Physicists (DPT) held in Muenster became an official conference of the DPG (German Physical Society). Various scientific groups working for equal opportunity have formed a "network of networks." At the DESY (German Electron Synchrotron), a group of women led by an equal opportunity officer is involved in the entire process of hiring new staff members in all positions, including directors.

    This spaceborne radar image of Munich, Germany illustrates the capability of a multi-frequency radar system to highlight different land use patterns in the area surrounding Bavaria's largest city. Central Munich is the white area at the middle of the image, on the banks of the Isar River. Pink areas are forested, while green areas indicate clear-cut and agricultural terrain. The Munich region served as a primary 'supersite' for studies in ecology, hydrology and radar calibration during the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) missions. Scientists were able to use these data to map patterns of forest damage from storms and areas affected by bark beetle infestation. The image was acquired by SIR-C/X-SAR onboard the space shuttle Endeavour on April 18, 1994. The image is 37 kilometers by 32 kilometers (23 miles by 20 miles) and is centered at 48.2 degrees North latitude, 11.5 degrees East longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations of the radar as follows: red is L-band, vertically transmitted and horizontally received; green is C-band, vertically transmitted and horizontally received; and blue is C-band vertically transmitted and received. SIR-C/X-SAR, a joint mission of the German, Italian, and United States space agencies, is part of NASA's Mission to Planet Earth.

    With the amendment of the German Medicinal Products Act in 1976 and the inclusion of naturopathy and homeopathy into the German Medical Licensure Act from 1988, the German government set up a comparatively favorable framework for Complementary and Alternative Medicine (CAM). But no comprehensive integration into the academic operating systems followed, because the universities as well as the legislative body seemed to have no further interest in CAM. Therefore, research projects in the field and suitable professorships had and still have to be financed by third-party funds. Notwithstanding the success of several CAM-projects, no sustainable development could be established: When the third-party funding runs off and the protagonists retire the institutional structures are supposed to vanish as well. Although the public demand for CAM is high in Germany, the administration detached homeopathy as a compulsory subject from the German Medical Licensure Act in 2002 and restricted severely the refunding of naturopathic medicines by the statutory health insurance in 2004. Moreover, the trend for CAM bashing takes root in the media. Unfortunately the CAM scene does not close ranks and is incapable to implement fundamental data collection processes into daily clinical routine: A wide range of data could justify further efforts to the government as well as to the scientific community. To say something positive, it must be mentioned that the scientific standard of CAM research is high for the most part and that third-party funded projects deliver remarkable results ever and on.

    The authors report full-information longitudinal age gradients in 4 intellectual abilities on the basis of 6-year longitudinal changes in 132 individuals (mean age at T1 = 78.27, age range = 70-100) from the Berlin Aging Study. Relative to the cross-sectional parent sample (N = 516, mean age at T1 = 84.92 years), this sample was positively selected because of differential mortality and experimental attrition. Perceptual speed, memory, and fluency declined with age. In contrast, knowledge remained stable up to age 90, with evidence for decline thereafter. Age gradients were more negative in old old (n = 66, mean age at T1 = 83.04) than in old (n = 66, mean age at T1 = 73.77) participants. Rates of decline did not differ reliably between men and women or between participants with high versus low life-history status. They conclude that intellectual development after age 70 varies by distance to death, age, and intellectual ability domain.

    The authors examined 3.7-year selectivity in the Berlin Aging Study by comparing the T1 parent sample (N = 516) with the T3 sample (N = 206). Selectivity was partitioned into a mortality-associated component, reflecting the degree to which individuals still alive at T3 (T3 survivors, N = 313) differ from the T1 parent sample (N = 516) from which they originated, and an experimental component, reflecting the degree to which the T3 sample (N = 206) differed from T3 survivors (N = 313). Across 48 variables representing medical, sensorimotor, cognitive, personality-related, and socioeconomic domains, the mortality-associated component accounted for 64% of total selectivity, and the experimental component for 36% (0.18 vs 0.10 SD units; t = 7.20, p <.01). Except for age and intelligence, experimental selectivity effects regarding means and prevalence rates were generally small. Partitioning selectivity into mortality-associated and experimental components is a useful tool in the longitudinal study of aging populations.

    Planetary Sciences teach us how special our homeplanet is in the solar system. Incorporating a broad variety of natural science topics they count to the most fundamental branches of scientific research with a strong interdisciplinary character. However, since planetary sciences are not a school subject, children as well as adults are often lacking an overall awareness and understanding of that field. The mission of planetary education has to be fulfilled by research institutions. With several platforms and activities our group is engaged to address this topic. The Planetary Sciences and Remote Sensing Group at Freie Universität Berlin (FUB) is involved in space missions such as Mars Express with the High Resolution Stereo Camera (HRSC), Cassini to Saturn, and Dawn to the asteroids Vesta and Ceres. Moreover, we participate in developing a planetary X-ray fluorescence spectrometer. Information of our planetary research activities can be found on our institutes website [1]. Our outreach activities include press releases, an image download hub, permanent and special exhibition support, 3D-HD-animation production, science fairs, workshops, hands-on courses, public talks at observatories and schools, as well as media appearances in radio, press and TV.

  15. The galvanic treatment of deafness and the trials at the Berlin Royal Deaf-Mute Asylum in 1802.

    PubMed

    2013-05-01

    In 1802, the director of the Berlin Royal Deaf-Mute Asylum, Ernst Adolph Eschke, performed an experiment to investigate the possibility of curing deafness by means of galvanism. This article explores the hope for a cure for deafness that was connected to the voltaic pile, and concludes that the treatment was based on insufficient knowledge of the aetiology of deafness. Furthermore, it uncovers the competition between the medical and the pedagogic approach to deafness that resulted from the purported cure. Comparing the approaches of different directors of galvanic experiments, divergences in attitudes between the medical and pedagogic realms are revealed. This is explained with reference to the contrasting motives and experiences of educational and medical professionals: the former had reasons to resist a cure to protect their profession, whereas the latter hoped for a medical breakthrough. Since the former had personal and long-lasting relationships to deaf people, while the latter only had brief encounters with deaf patients, the physicians were also more prone to objectify their trial subjects. The report from Eschke's trials is presented as an early document of deaf reactions to attempts to restore their hearing, showing that resistance to medical interventions were prevalent among the deaf already in the early nineteenth century.

    A new central railway station - Lehrter Bahnhof - is being built in Berlin. Because of construction activities in immediate vicinity and because of difficult soil conditions, different vertical displacements have to be expected. In order to avoid damage to the bridges and to a widely spanned glass roof which will be supported by two concrete bridges these two bridges have to be monitored with regard to their deformation performance right from the beginning of construction until commissioning as well as later on for several years. For this purpose, a monitoring concept has been developed and sensors with excellent long-term stability have been chosen. This paper describes the system for monitoring settlements and heaves by means of laser-based optics and hydrostatic leveling. Additionally, strain and inclination of the prestressed concrete bridges are redundantly monitored by embedded long-gage length fiber-optic strain sensors as well as resistive strain gages, and inclinometers. Measurements on-site are referenced by measurements on two test beams well-defined loaded under laboratory and field conditions. The paper also describes the measuring concept and the sensor techniques as well as installation of the sensor system and first results.

    This study investigated differences in prevalence and determinants of HIV infection, and in recent risk behaviour (previous 6 months) among injecting drug users (IDUs) who are in contact with different types of services for IDUs in Berlin. Participants (n = 557) were recruited from drug-free long-term treatment centres, a storefront agency and a syringe exchange bus. HIV seroprevalence was lowest (3.9%) at the treatment centres, and highest among IDUs at the storefront agency (20.7%). In logistic regression, independent risk factors for HIV infection were duration of injecting drug use, borrowing syringes in prison, sex with HIV-positive partners, and prostitution. Syringe sharing in prison was the most important independent determinant of HIV infection among all three subpopulations of IDUs. Participants entering long-term treatment were most likely, and IDUs at the syringe exchange bus were least likely to have borrowed and passed on syringes in the previous 6 months. In logistic regression, site of recruitment was independently associated with recent borrowing of syringes, but not with condom use. Injection of drugs other than heroin only, and injecting in prisons, were also independent predictors of recent borrowing. The results indicate that IDUs entering treatment form an important target group for health education. There is a need for AIDS prevention measures in prisons. The comparatively low levels of recent injection risk behaviour among IDUs at the syringe exchange bus suggest that this type of intervention may be effective in harm reduction.

    BioRef is a versatile novel time-of-flight reflectometer featuring a sample environment for in situ infrared spectroscopy at the reactor neutron source BER II of the Helmholtz Zentrum Berlin für Materialien und Energie (HZB). After two years of design and construction phase the instrument has recently undergone commissioning and is now available for specular and off-specular neutron reflectivity measurements. BioRef is especially dedicated to the investigation of soft matter systems and studies at the solid-liquid interface. Due to flexible resolution modes and variable addressable wavelength bands that allow for focusing onto a selected scattering vector range, BioRef enables a broad range of surface and interface investigations and even kinetic studies with subsecond time resolution. The instrumental settings can be tailored to the specific requirements of a wide range of applications. The performance is demonstrated by several reference measurements, and the unique option of in situ on-board infrared spectroscopy is illustrated by the example of a phase transition study in a lipid multilayer film.

    Results of the veterinary examination of feral cats living in a delimited area of Berlin city are presented. Between 1996 and 1999 thirty nine cats were investigated, among them eleven individuals twice. All animals were positive for one or several pathologies, but only seven cats were in bad condition. Most common were periodontal and gingival diseases, followed by conjunctivitis. Five cats were positive for FIV, seven for FeLV, one tomcat for both. Twenty six cats vanished during the study period of 42 months, only one third of cats survived and remained in the study area throughout. Four cats were given to pet lovers, nine cats disappeared without trace, seven animals died in traffic accidents and six cats died of illnesses. Cats less than three years of age vanished more often than expected from their representation in the population. Dirty or large feeding places for cats constitute a source of infections. Feeding sites should be accessible to only few individuals and left-overs that may attract stray cats, rats or birds should not remain at feeding places.

    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.

    Abstract The type status is described of 96 taxa classified within the superfamily Orthalicoidea and present in the Mollusca collection of the Museum für Naturkunde der Humboldt-Universität zu Berlin. Lectotypes are designated for the following taxa: Orthalicus elegans Rolle, 1895; Bulimus maranhonensis Albers, 1854; Orthalicus nobilis Rolle, 1895; Orthalichus tricinctus Martens, 1893. Orthalicus sphinx tresmariae is introduced as new name for Zebra sphinx turrita Strebel, 1909, not Zebra quagga turrita Strebel, 1909. The following synonyms are established: Zebra crosseifischeri Strebel, 1909 = Orthalicus princeps fischeri Martens, 1893; Orthalicus isabellinus Martens, 1873 = Orthalicus bensoni (Reeve, 1849); Zebra zoniferus naesiotes Strebel, 1909 = Orthalicus undatus (Bruguière, 1789); Porphyrobaphe (Myiorthalicus) dennisoni pallida Strebel, 1909 = Hemibulimus dennisoni (Reeve, 1848); Zebra delphinus pumilio Strebel, 1909 = Orthalicus delphinus (Strebel, 1909); Orthalicus (Laeorthalicus) reginaeformis Strebel, 1909 = Corona perversa (Swainson, 1821); Bulimus (Eurytus) corticosus Sowerby III, 1895 = Plekocheilus (Eurytus) stuebeli Martens, 1885. The taxon Bulimus (Eudioptus) psidii Martens, 1877 is now placed within the family Sagdidae, tentatively in the genus Platysuccinea. Appendices are included with an index to all the types of Orthalicoidea extant (including those listed by Köhler 2007) and a partial list of letters present in the correspondence archives.

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

    PubMed

    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.

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

    AgI-based fast-ion conducting glasses with very high AgI compositions from the (AgI)x(AgPO3)1-x, (AgI)x(Ag2PO3.5)1-x, and (AgI)x(Ag3PO4)1-x systems were prepared successfully by using a rapid-press quenching and a twin-roller quenching method. The ac dielectric measurements showed common relaxation properties of Ag+-ion conduction in the glasses independently of the species of the glass network formers of AgPO3, Ag2PO3.5, and Ag3PO4, and the activation energies, Δɛa, for Ag+-ion conduction were observed to converge upon the same magnitude of ~26 kJ mol-1 at the AgI composition limit of x = 1. This indicates the formation of amorphous AgI regions in the glasses, and the value of Δɛa = 26 +/- 1 kJ mol-1 estimated at x = 1 was concluded to correspond to that for bulk amorphous AgI which has never been obtained experimentally.

    A facile approach to the synthesis of novel CNT-Ag and GO-Ag antibacterial materials, in which thiol groups are utilized as linkers to secure silver (Ag) nanoparticles to the CNT and GO surfaces without agglomeration, is reported. The resulting CNT-Ag and GO-Ag samples were characterized by performing TEM, XRD, Auger, XPS, and Raman measurements, which revealed that in these antibacterial materials size-similar and quasi-spherical Ag nanoparticles are anchored to the CNT and GO surfaces. The Ag nanoparticles in CNT-Ag and GO-Ag have narrow size distributions with average diameters of 2.6 and 3.5 nm respectively. The antibacterial activities of CNT-Ag and GO-Ag against Escherichia coli were assessed with the paper-disk diffusion method and by determining the minimal inhibitory concentrations (MICs). CNT-Ag was found to have higher antibacterial activity than the reference Ag colloid. Moreover, both CNT-Ag and GO-Ag retain more than 50% of their original antibacterial activities after 20 washes with detergent, which indicates their potential as antibacterial materials for laboratory and medical purposes.

    The diverse mechanism of antimicrobial activity of Ag and AgBr nanoparticles against gram-positive and gram-negative bacteria and also against several strains of candida was explored in this study. The AgBr nanoparticles (NPs) were prepared by simple precipitation of silver nitrate by potassium bromide in the presence of stabilizing polymers. The used polymers (PEG, PVP, PVA, and HEC) influence significantly the size of the prepared AgBr NPs dependently on the mode of interaction of polymer with Ag+ ions. Small NPs (diameter of about 60–70 nm) were formed in the presence of the polymer with low interaction as are PEG and HEC, the polymers which interact with Ag+ strongly produce nearly two times bigger NPs (120–130 nm). The prepared AgBr NPs were transformed to Ag NPs by the reduction using NaBH4. The sizes of the produced Ag NPs followed the same trends – the smallest NPs were produced in the presence of PEG and HEC polymers. Prepared AgBr and Ag NPs dispersions were tested for their biological activity. The obtained results of antimicrobial activity of AgBr and Ag NPs are discussed in terms of possible mechanism of the action of these NPs against tested microbial strains. The AgBr NPs are more effective against gram-negative bacteria and tested yeast strains while Ag NPs show the best antibacterial action against gram-positive bacteria strains. PMID:25781988

    The low temperature sintering behaviour of nanocrystalline Ag powder (with an average size of 70 nm) was characterized. Using spark plasma sintering (SPS), the Ag nanopowders can be successfully sintered at low pressure for only 5 min without external heating, and the sintering density increases and porosity decreases significantly with increase in the sintering temperature. Nanoindentation has been used to characterize the SPS sintered Ag samples. The mechanisms of the low sintering temperature behaviour of the nano-Ag powder and the nanoscale mechanical performance have been discussed. Compression tests were also used to characterize the mechanical properties of the sintered Ag sample with a maximum strain up to 15%.

    Clinical diagnostic procedure using positron emission tomography (PET) requires high costs. To promote clinical use of PET, sociomedical evaluation is necessary. In this paper, sociomedical situations concerning clinical use of PET in Germany is reported. Some comparisons are made between Japan and this country putting emphases on several points such as 1) number of cyclotron and PET facilities, 2) social restriction to transportation of radioisotopes, 3) activities of satellite PET facilities, and 4) clinical indications for PET studies. Number of cyclotron was larger in Japan (29) than in Germany (17), but number of PET facilities was larger in Germany (47) than in Japan (29). The reason seems that in Germany transportation and buying of radioisotopes is less restricted. Hence, more than half of PET facilities in Germany are "satellite facilities" which do not have their own cyclotrons. Radioisotope distribution seems to serve as a backbone of "satellite concept." Additionally in Germany, list of clinical indications for PET study is almost completed and now is widely in applied to most cases. To promote clinical use of PET in Japan, the German system might serve as an important socioeconomic model in Europe instead of the United States.

    Background: Tonsillectomy rates vary considerably among different states, regions, and times. This study was conducted to identify the prevalence of “chronic” tonsillitis, peritonsillar abscess, hypertrophy of the tonsils with and without adenoids in absolute and relative numbers in an 80 million people nation. Moreover, the number and rates of different surgical procedures to resolve either “chronic” tonsillitis, peritonsillar abscess, or upper airway obstruction due to (adeno)tonsillar hypertrophy over several years was evaluated in this study (tonsillectomy, adenotonsillectomy, tonsillotomy, abscess tonsillectomy, transoral incision and drainage). Finally, the post-tonsillectomy hemorrhage rate was calculated and analyzed in relation to age and gender. Material and methods: Calculations were based on data as published by the Federal Institute of Statistics or on request, if needed. The latest data were provided for 2013. Results: The total number of the aforementioned diseases (stratified by ICD-10) decreased from 142,574 (in 2000) to 87,624 in 2013 (38.5%). Tonsillectomy, with or without adenoidectomy, was performed in a total of 833,896 patients between 2006 and 2013 in Germany. The yearly number decreased continually from 120,993 in 2006 to 84,332 procedures in 2013 (30.3%). The most significant decrease was registered in patients younger than 20 years of age for this time period: 70.92 per 10,000 in 2010 to 58.68 per 10,000 in 2013. If all age groups were included, the rate decreased from 13.34 per 10,000 to 10.90 per 10,000. In contrast, an increasing number of tonsillotomies was observed between 2007 (4,659 procedures) and 2013 (11,493). The cumulated number of procedures was 59,049. A constant number of 15,000 cases with peritonsillar abscess were diagnosed per year in Germany (19 patients per 100,000). The prevalence increased significantly at an age of 15 years and there was a preponderance of female patients below that age. Compared to the

    An interfacial lattice Ag(+) doped on TiO2 (Ag(+)/TiO2) was prepared by eluting Ag(0) clusters from a hydrothermally prepared Ag(0)/Ag(+)/TiO2 composite. An Ag(+)/TiO2@Ag(0) composite photocatalyst was subsequently obtained via a secondary Ag(0) clusters loading process to the Ag(+)/TiO2. The photocatalytic activity of Ag(+)/TiO2@Ag(0) was greatly improved compared to Ag(0)/Ag(+)/TiO2 and Ag(+)/TiO2. X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry (CV) testing verified that Ag(+) ions occur as an interfacial lattice Ag(+) species in the composites. The enhancement effect of the interfacial lattice Ag(+) species is exhibited by the newly-formed Ag(+)/TiO2@Ag(0) as the interfacial lattice Ag(+) is fully exposed but not overlapped with the re-loaded Ag(0) clusters. The interfacial lattice Ag(+) ions and Ag(0) clusters are both responsible for the photocatalytic performance improvement of the catalyst, in either the photocatalytic degradation of methyl orange or photocurrent measurement.

    The influence of surface mechanical attrition treatment (SMAT) on Ag precipitation in Cu-Ag alloys was investigated. Cu-6 wt% Ag was melt, cold rolled and solution treated to be Cu-Ag solid solution, which was either aged at 250 and 350 °C for 24 h directly or SMAT-ed before aging. Ag precipitates were hard be found in the directly aged Cu-Ag sample while they were observed clearly in the SMAT-ed counterpart at 250 °C. The Ag precipitates formed in the surface layer by SMAT are much coarser than those in the un-SMAT-ed sample. It is obvious that the precipitating behavior of Ag was promoted significantly by SMAT approach. A large number of defects were generated by SMAT and they were acting as fast atomic diffusion channels that facilitated the atomic diffusion of Ag.

    Since 1990 in Berlin the building blueprints and potaining documents for public utility buildings, in particular schools and child-care centres, have been serutinised and/or buildings have been visited for the possibility of the presence of elastic sealants containing PCB. Pursuant to this, samples of the sealing material of suspected buildings were examined and air in the rooms was measured. Results of measurements (n = 410) in community rooms of schools and child-care centres were an average value of 114 ng/m3 (maximum 7.360 ng/m3) and a geometrical mean of 155 ng/m3. For measurements in schools (n = 308), the geometrical mean was 229 ng/m3, whereas in child-care centres (n = 102) it was 48 ng/m3. Within the framework of the procedural method described above regarding the investigation of suspected buildings, about 15% of the school buildings and 3% of the child-care centres had indoor air values of over 300 ng/m3 (value indicating need for taking precautions) and 5% of the school buildings had more than 3.000 ng/m3 (the value warranting an intervention, according to the now defunct Federal Health Office). No values over 3.000 ng/m3 have been measured up to now in the community rooms of child-care centres. The investigations carried out throughout the Berlin Borough of Tiergarten of all school and child-care centre buildings yielded the results that about 13% of the schools and about 4% of the child-care centres had rooms with air values above 300 ng/m3. Only one school (4%), but none of the child-care centres investigated had values of more than 3.000 ng/m3. We are of the opinion that this proves the need for the creation of an on-target survey of the concrete pollution situation and short-term adoption of exposure-reducing measures or renovations. In any case the exposure of children to this toxicologically suspect substance by this additional way of pollution must be kept as low as possible. In addition to the description of a recently concluded PCB renovation

    Just in time for teh 500th anniversary of the count palatine and later elector Ottheinrich (1502-1558) in April 2002, it became known that to this Renaissance rule we owe the earliest pictures of towns and residences from Upper Bavaria, Franconia and the Upper Palatine, from Bohemia, Silesia, Poland, Brandenburg and Saxonia. These pictures are the first series of town views after the wood engravings of the Schedel World Chronicle of 1493. Fifty plates in the size of about 30 x 40-86 cm show seventy town views, of which before only the cities of Breslau, Neisse, Prag and Eichstätt were reproduced in the work of 1493. For centuries the genesis of these pen-and-ink-drawings, coloured with watercolour and opaque water colour and ornamented with heightened gold, lay in obscurity. We only knew that they came from the monastery of Ebrach to the university library of Wurzburg in the course of teh secularisation in the year 1803. Lately these pictures, that show no signatures, but only the names of towns in the banderoles, could be identified as picture documents of a rather unknown journey of the Count Palatine Ottheinrich to Cracow and Berlin. The reason for Ottheinrich's journey was to discharge the unpaid promissory note of the marriage portion of his grandmother, the Polish Princess Hedwig who had married George the Rich of Bavaria-Landshut in 1475. The examination of hte pictures and their genesis, made by Angelika Marsch together with ten German, Polish and Czech scientists, also led to the finding of hitherto unknown documents proving that Ottheinrich's ride to his great-uncle King Sigismund the Elder had been successful. These documents also show by whom Ottheinrich was accompanied and why he didn't choose the direct way back from Cracow to Neuburg, but via Berlin. These journey pictures of Ottheinrich date fom the early times of the depiction of real towns. At the same time the first handed down picture documentation of a principal journey is of great interest

    Treatment with L-asparaginase is associated with coagulation disturbances with deep venous thrombosis being the most common clinical consequence. Use of the calibrated automated thrombogram allows precise estimation of thrombin generated in vitro. We show the first data on thrombin generation, measured by calibrated automated thrombography (CAT), in children with acute lymphoblastic leukemia treated with L-asparaginase. Thrombin generation was measured by means of CAT in 23 children treated for acute lymphoblastic leukemia. Samples were obtained at predefined time points during the induction and reinduction phase of acute lymphoblastic leukemia-intercontinental Berlin-Frankfurt-Münster (BFM) 2000 or Associazione Italiana Ematologica Oncologia Pedaitrica Interim BFM 2000 protocols. Antihrombin and fibrinogen were measured on the same sample. Twenty-eight sets of thrombin generation measurements were collected from 23 patients. We observed no significant effect of antithrombin deficiency and/or hypofibrinogenemia on thrombin generation. Endogenous thrombin generation and peak thrombin were significantly higher during induction than in the reinduction phase (P < 0.001). Four patients with severe infection experienced an increase in thrombin generation, reaching maximum in a median of 7.5 days after the onset of infection. Two of those patients developed deep venous thrombosis at the time of peaked endogenous thrombin generation. Thrombin generation in children with acute lymphoblastic leukemia treated according to BFM protocols is significantly higher during the induction phase compared with reinduction and is not substantially affected by hypofibrinogenemia and/or antithrombin deficiency. Severe infection during the induction phase enhances thrombin generation with subsequent risk of thrombosis.

    Background Various trials report improved outcomes for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) treated with pediatric- based regimens. This prompted the investigation of the pediatric Augmented Berlin-Frankfurt-Münster (ABFM) regimen in AYA patients. Results were compared with the hyper–fractionated cyclophosphamide, vincristine, Adriamycin and dexamethasone (hyper-CVAD) regimen in a similar population. Methods Eighty-five patients age 12 to 40 years with Philadelphia chromosome- (Ph) negative ALL were treated with ABFM from 10/2006 through 4/2012. Their outcome was compared to 71 historical AYA patients treated with hyper-CVAD from our institution. Patient and disease characteristics, as well as status of minimal residual disease (MRD), were analyzed for their impact on outcomes. Results The complete remission (CR) rate with ABFM was 94%. The 3-year complete remission duration (CRD) and overall survival (OS) rates were 70% and 74%, respectively. The 3-year CRD and OS were 72% and 85%, respectively, with age ≤ 21 years, and 69% and 60%, respectively, with age 21-40 years. Initial white blood cell count was an independent predictive factor of OS and CRD. The MRD status on Day 29 and Day 84 of therapy were also predictive of long-term outcomes. Severe regimen toxicities included transient hepatotoxicity in 35-39%, pancreatitis in 11%, osteonecrosis in 11%, and thrombosis in 22%. The 3-year OS rate was 74% with ABFM versus 71% with hyper-CVAD; the 3-year CRD rate was 70% with ABFM versus 66% with hyper-CVAD. Conclusion ABFM was tolerable in AYA patients with ALL but was not associated with significant improvements in CRD and OS compared with hyper-CVAD. PMID:25042398

  14. Relationships and sexuality of imprisoned men in the German penal system--a survey of inmates in a Berlin prison.

    2012-01-01

    The lack of concrete scientific data on the sexual behavior of inmates in German prisons is surprising, especially given the extant international scholarship on prison culture and sexual violence. Historically, the most influential publications were Clemmer's "The Prison Community", and Sykes's "The Society of Captives", which both addressed the importance of sexual deprivation and analyzed the impact of sexual victimization on prisoners. Different forms of homosexual contact between inmates include prostitution and "protective pairing", both characterized as "dark" issues--nonconsensual sexual acts--which still have not been scientifically researched. The United States enacted the Prison Rape Elimination Act, 2003, revealing nationwide data on the prevalence of sexual assault within correctional facilities. Prison inmates suffer not only from separation from their spouses or partners, but also from sexual harassment, extortion, and the threat of rape, which has multiple implications for their mental and physical health. This article presents the first German study to record data about the relationships and sexuality of imprisoned men, and was conducted in an adult correctional facility for long-term prisoners in Berlin-Tegel. The survey, which is based on results from a questionnaire taken by voluntary study participants, had a special focus on the occurrence of consensual homoerotic contacts between heterosexual inmates. The emphasis was on the potential impact of such contact on role behavior during confinement, as well as the impact on sexual identity after release. The survey revealed the first data on the incidence and prevalence of sexual violence and coercion within correctional facilities. This article presents the results of this survey for the first time.

    Objective: Despite the improvement in ventricular assist device (VAD) therapy in adults and in adolescents, in infant population only Berlin Heart EXCOR (BHE) is licensed as long term VAD to bridge children to Heart Transplantation (HTx). Particularly demanding in terms of morbidity and mortality are smallest patients namely the ones implanted in the first year of life or with a lower body surface area. This work aims at retrospective reviewing a single center experience in using BHE in children with a body weight under 10 kg. Methods: Data of all pediatric patients under 10 kg undergoing BHE implantation in our institution from March 2002 to March 2016 were retrospectively reviewed. Results: Of the 30 patients enrolled in the study, 53% were male, 87% were affected by a dilated cardiomyopathy with an average weight and age at the implantation of 6.75 ± 2.16 Kg and 11.57 ± 10.12 months, respectively. Three patients (10%) required a BIVAD implantation. After the implantation, 7 patients (23%) required re-intervention for bleeding and 9 patients (30%) experienced BHE cannulas infection. A total of 56 BHE pump were changed for thrombus formation (1.86 BHE pump for patient). The average duration of VAD support was 132.8 ± 94.4 days. Twenty patients (67%) were successfully transplanted and 10 patients (33%) died: 7 for major neurological complication and 3 for sepsis. Conclusion: Mechanical support in smaller children with end stage heart failure is an effective strategy for bridging patients to HTx. The need for BIVAD was relegated, in the last years, only to restrictive cardiomiopathy. Further efforts are required in small infants to improve anticoagulation strategy to reduce neurological events and BHE pump changes. PMID:27999550

    Climate change is driven by global processes such as the global ocean circulation and its variability over time leading to changing weather patterns on regional scales as well as changes in the severity and occurrence of extreme events such as heat waves. For example, the summer 2003 European heat wave caused up to 70.000 excess deaths over four months in Central and Western Europe. As around 75% of Europe's population resides in urban areas, it is of particular relevance to examine the impact of seasonal to decadal-scale climate variability on urban areas and their populations. This study aims at downscaling the spatially coarse resolution CMIP5 climate predictions to the local urban scale and investigating the relation between heat waves and the urban-rural temperature increment (urban heat island effect). The resulting heat stress effect is not only driven by climatic variables but also impacted by urban morphology. Moreover, the exposure varies significantly with the geographical location. All this information is coupled with relevant socio-economic datasets such as population density, age structure, etc. focussing on human health. The analyses are conducted in the framework of the NACLIM FP7 project funded by the European Commission involving local stakeholders such as the cities of Antwerp (BE), Berlin (DE) and Almada (PT) represented by different climate and urban characteristics. The end-user needs have been consolidated in a climate services plan including the production of heat risk exposure maps and the analysis of various scenarios considering e.g. the uncertainty of the global climate predictions, urban expansion over time and the impact of mitigation measures such as green roofs. The results of this study will allow urban planners and policy makers facing the challenges of climate change and develop sound strategies for the design and management of climate resilient cities.

    A phase transition from the cubic CsCl-type structure (Pm-3m space group) into a tetragonal UPb-type structure (I4 1/amd) is observed for the LiAg binary compound at ambient conditions. The crystal structure of the tetragonal modification of the LiAg binary compound was solved by direct methods in SHELXS on the base of structure factors which were extracted from a powder diffraction pattern and refined by SHELXL and the Rietveld method ( a = 3.9605(1), c = 8.2825(2) Å, Bragg R-factor = 4.81, Rf-factor = 4.87). Elevated temperatures and/or a small Li-excess versus the equimolar composition favour the cubic structure whereas ambient and lower temperatures and/or a small Li-deficiency stabilize the tetragonal structure. This reconstructive transition is reversible but proceeds slowly.

    Objective: The evaluation of medical research performance is a key prerequisite for the systematic advancement of medical faculties, research foci, academic departments, and individual scientists’ careers. However, it is often based on vaguely defined aims and questionable methods and can thereby lead to unwanted regulatory effects. The current paper aims at defining the position of German academic medicine toward the aims, methods, and consequences of its evaluation. Methods: During the Berlin Forum of the Association of the Scientific Medical Societies in Germany (AWMF) held on 18 October 2013, international experts presented data on methods for evaluating medical research performance. Subsequent discussions among representatives of relevant scientific organizations and within three ad-hoc writing groups led to a first draft of this article. Further discussions within the AWMF Committee for Evaluation of Performance in Research and Teaching and the AWMF Executive Board resulted in the final consented version presented here. Results: The AWMF recommends modifications to the current system of evaluating medical research performance. Evaluations should follow clearly defined and communicated aims and consist of both summative and formative components. Informed peer reviews are valuable but feasible in longer time intervals only. They can be complemented by objective indicators. However, the Journal Impact Factor is not an appropriate measure for evaluating individual publications or their authors. The scientific “impact” rather requires multidimensional evaluation. Indicators of potential relevance in this context may include, e.g., normalized citation rates of scientific publications, other forms of reception by the scientific community and the public, and activities in scientific organizations, research synthesis and science communication. In addition, differentiated recommendations are made for evaluating the acquisition of third-party funds and the

    The dietary intake of aspartame, cyclamate, and saccharin was evaluated in Germany (FRG) in 1988/89. In the first part of the study the sweetener intake was evaluated in a representative sample of the population. Complete 24-h records of the amount and type of all foods and drinks consumed were obtained from 2,291 individuals. The total daily intake was calculated for each person from the sweetener content of each product and was expressed in mg/kg body weight (bw). 35.9% of the participants ingested one or more sweeteners on the examination day. Cyclamate and saccharin were the prominent sweeteners because aspartame was at that time permitted only under special regulatory exemption, and products containing acesulfame were not yet available. For users of intense sweeteners the mean intakes of aspartame, cyclamate, and saccharin were 0.15, 2.62, and 0.250 mg/kg bw/day, respectively. At the 90th percentile of intake, i.e., for the heavy consumer, the ingestion of cyclamate and saccharin was about 2.5 times higher. Persons who adhered to a diet (diabetes, weight control) did not ingest sweeteners in substantially higher amounts. Tabletop sweeteners and beverages were the most important sources of sweeteners, and they contributed more than 80% of the total intake. Consumption of sweeteners in excess of the Acceptable Daily Intake (ADI) was rarely observed (saccharin: one person, cyclamate: 16 persons). In the second part of the study, the sweetener intake was further evaluated during a 7-day period in those subjects who in the 1-day study ingested any of the sweeteners in excess of 75% of the ADI. Complete 7-day food records were available from 40 out of the 41 subjects who fulfilled this criterium. In this selected subgroup in which 19 subjects were less than 19 years old, the mean daily intakes of aspartame, cyclamate, and saccharin were 0.13, 4.53, and 0.42 mg/kg body weight (bw), respectively. These levels correspond to 0.33, 41 and 17% of the corresponding ADI

    On 6th April 1945, nine days before the liberation of the Bergen Belsen Concentration Camp, about 2,500 Jewish prisoners were ordered to prepare to leave the camp on the next day. On 7th April, the prisoners left through the gates of the camp and began to walk about 10 kilometers to the train station near the city of Celle. There they were ordered to board a train that would take them to the Theresienstadt Concentration Camp. After six days of travel, the train stopped near the village of Farsleben, Germany, where it was liberated by the 743rd Tank Battalion of the 30th Infantry Division, of the U.S. 9th Army, on 13th April 1945. The 105th Medical Battalion of the same Division was the primary care provider for the survivors, who were then taken in vehicles available from the 30th Infantry Division, and organized into a convoy by the Division's Liaison Officer, Lt. Frank W. Towers, to the town of Hillersleben. A former German Air Force Base was located at Hillersleben with a small hospital that could not provide medical attention to all the survivors. On 21st April, Company C of the 95th Medical Battalion, received an order to go to Hillersleben. Colonel Dr. William W. Hurteau, the Commanding Officer of this Battalion, determined that the biggest task given to the Battalion during World War II, was establishing another hospital in the town of Hillersleben and providing additional beds in the existing hospital, which was a structure that had served as a boarding school. Furthermore, they needed to acquire hospital equipment which was obtained from German equipment and supplies that had been captured by the U.S. MiLitary. Also, they took care of obtaining food supplies from German warehouses, and meat and milk from local dairy farms. The lives of the prisoners on this train were saved by the heroism and dedicated work of those brave soldiers of the 30th Infantry Division and the 95th Medical Battalion.

    Drinking water shortage has become worse in recent decades. A new capacitive deionization (CDI) method for increasing water supplies through the effective desalination of seawater has been developed. Silver as nano Ag and Ag@C which was prepared by carbonization of the Ag(+)-β-cyclodextrin complex at 573 K for 30 min can add the antimicrobial function into the CDI process. The Ag@C and Ag nanoparticles dispersed on reduced graphene oxide (Ag@C/rGO and nano Ag/rGO) were used as the CDI electrodes. The nano Ag/rGO and Ag@C/rGO electrodes can reduce the charging resistant, and enhance the electrosorption capability. Better CDI efficiencies with the nano Ag/rGO and Ag@C/rGO electrodes can therefore be obtained. When reversed the voltage, the electrodes can be recovered up to 90% within 5 min. This work presents the feasibility for the nano Ag and Ag@C on rGO electrodes applied in CDI process to produce drinking water from seawater or saline water.

    A facile, eco-friendly and inexpensive method to prepare Ag2S short nanorods and S-Ag nanocomposites using sublimed sulfur, AgNO3, PVP and PEG400 was studied. According to x-ray diffraction and scanning electron microscopy of the Ag2S, the products are highly crystalline and pure Ag2S nanorods with diameters of 70-160 nm and lengths of 200-360 nm. X-ray diffraction of the S-Ag nanocomposites shows that we obtained cubic Ag and S nanoparticles. Transmission electron microscopy shows that the molar ratio of PVP to Ag+ plays an important role in controlling the size and morphology of the S-Ag nanocomposites. When the molar ratio of PVP to Ag+ was 10:1, smaller sizes, better dispersibility and narrower distribution of S-Ag nanocomposites with diameters of 10-40 nm were obtained. The formation mechanism of the S-Ag nanocomposites was studied by designing a series of experiments using ultraviolet-visible measurement, and it was found that S nanoparticles are produced first and act as seed crystals; then Ag+ becomes Ag nanocrystals on the surfaces of the S nanoparticles by the reduction of PVP. PEG400 acts as a catalyzer, accelerating the reaction rate, and protects the S-Ag nanocomposites from reacting to produce Ag2S. The antimicrobial experiments show that the S-Ag nanocomposites have greater antimicrobial activity on Staphylococcus aureus, Aspergillus niger and blue mold than Ag nanoparticles.

    Highlights: • AgI/Ag{sub 3}PO{sub 4} hybrid was prepared via an in situ anion-exchange method. • AgI/Ag{sub 3}PO{sub 4} displays the excellent photocatalytic activity under visible light. • AgI/Ag{sub 3}PO{sub 4} readily transforms to be Ag@AgI/Ag{sub 3}PO{sub 4} system. • h{sup +} and O{sub 2}{sup ·−} play the major role in the AO 7 decolorization over AgI/Ag{sub 3}PO{sub 4}. • The activity enhancement is ascribed to a Z-scheme system composed of Ag{sub 3}PO{sub 4}, Ag and AgI. - Abstract: Highly efficient visible-light-driven AgI/Ag{sub 3}PO{sub 4} hybrid photocatalysts with different mole ratios of AgI were prepared via an in situ anion-exchange method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–vis diffuse reflectance spectroscopy (DRS) and photoluminescence (PL) technique. Under visible light irradiation (>420 nm), the AgI/Ag{sub 3}PO{sub 4} photocatalysts displayed the higher photocatalytic activity than pure Ag{sub 3}PO{sub 4} and AgI for the decolorization of acid orange 7 (AO 7). Among the hybrid photocatalysts, AgI/Ag{sub 3}PO{sub 4} with 80% of AgI exhibited the highest photocatalytic activity for the decolorization of AO 7. X-ray photoelectron spectroscopy (XPS) results revealed that AgI/Ag{sub 3}PO{sub 4} readily transformed to be Ag@AgI/Ag{sub 3}PO{sub 4} system while the photocatalytic activity of AgI/Ag{sub 3}PO{sub 4} remained after 5 recycling runs. In addition, the quenching effects of different scavengers displayed that the reactive h{sup +} and O{sub 2}{sup ·−} play the major role in the AO 7 decolorization. The photocatalytic activity enhancement of AgI/Ag{sub 3}PO{sub 4} hybrids can be ascribed to the efficient separation of electron–hole pairs through a Z-scheme system composed of Ag{sub 3}PO{sub 4}, Ag and AgI, in which Ag nanoparticles act as the charge separation center.

    Using tobacco industry documents, we examined how and why the tobacco industry sought to influence science and scientists in Germany as a possible factor in explaining the German opposition to stricter tobacco regulation. Smoking and health research programs were organized both separately by individual tobacco companies and jointly through their German trade organization. An extensive network of scientists and scientific institutions with tobacco industry links was developed. Science was distorted in 5 ways: suppression, dilution, distraction, concealment, and manipulation. The extent of tobacco industry influence over the scientific establishment in Germany is profound. The industry introduced serious bias that probably influenced scientific and public opinion in Germany. This influence likely undermined efforts to control tobacco use.

    Hugger, A; Hugger, S; Kordass, B

    2011-09-01

    In Germany, the dental curriculum is still based on dental licensing regulations ("Approbations-/Prüfungsordnung für Zahnärzte") from 1955. Essential changes of the dental licensing regulations have not been made for over 50 years-unlike the medical licensing regulations in Germany. Teaching and learning concepts have, nevertheless, changed considerably in medical and dental education over time. The present study delivers an analysis about reform initiatives in dental education in Germany and introduces examples of innovative projects. To be able to establish long-term and broad reforms in dental education, new licensing regulations for dentists are required. This should create a contemporary framework for education, which assigns resources and enables occupational profile development at specific locations. Thereby, compatibility with the medical curriculum has to be guaranteed just as required adaptations of admission and curricular capacity regulations for dentistry.

  12. Space Radar Image of North Sea, Germany

    1994-01-01

    This is an X-band image of an oil slick experiment conducted in the North Sea, Germany. The image is centered at 54.58 degrees north latitude and 7.48 degrees east longitude. This image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on October 6, 1994, during the second flight of the spaceborne radar. The experiment was designed to differentiate between petroleum oil spills and natural slicks floating on the sea surface. Two types of petroleum oil and six types of oils resembling natural sea surface slicks were poured on the sea surface from ships and a helicopter just before the space shuttle flew over the region. At the bottom of the image is the Sylt peninsula, a famous holiday resort. Twenty-six gallons (100 liters) of diesel oil was dissipated due to wave action before the shuttle reached the site. The oil spill seen at the uppermost part of the image is about 105 gallons (400 liters) of heavy heating oil and the largest spill is about 58 gallons (220 liters) of oleyl alcohol, resembling a 'natural oil' like the remaining five spills used to imitate natural slicks that have occurred offshore from various states. The volume of these other oils spilled on the ocean surface during the five experimental spills varied from 16 gallons to 21 gallons (60 liters to 80 liters). The distance between neighboring spills was about half a mile (800 meters) at the most. The largest slick later thinned out to monomolecular sheets of about 10 microns, which is the dimension of a molecule. Oceanographers found that SIR-C/X-SAR was able to clearly distinguish the oil slicks from algae products dumped nearby. Preliminary indications are that various types of slicks may be distinguished, especially when other radar wavelengths are included in the analysis. Radar imaging of the world's oceans on a continuing basis may allow oceanographers in the future to detect and clean up oil spills much more

    This is a false-color, three-frequency image of the Oberpfaffenhofen supersite, southwest of Munich in southern Germany, which shows the differences in what the three radar bands can see on the ground. The image covers a 27- by 36-kilometer (17- by 22-mile) area. The center of the site is 48.09 degrees north and 11.29 degrees east. The image was acquired by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard space shuttle Endeavour on April 13, 1994, just after a heavy storm which covered the all area with 20 centimeters (8 inches) of snow. The dark area in the center of the image is Lake Ammersee. The two smaller lakes above the Ammersee are the Worthsee and the Pilsensee. On the right of the image is the tip of the Starnbergersee. The outskirt of the city of Munich can be seen at the top of the image. The Oberpfaffenhofen supersite is the major test site for X-SAR calibration and scientific experiments such as ecology, hydrology and geology. This color composite image is a three-frequency overlay. L-band total power was assigned red, the C-band total power is shown in green and the X-band VV polarization appears blue. The colors on the image stress the differences between the L-band, C-band and X-band images. If the three frequencies were seeing the same thing, the image will appear in black and white. For example, the blue areas corresponds to area for which the X-band backscatter is relatively higher than the backscatter at L-and C-band; this behavior is characteristic of clear cuts or shorter vegetation. Similarly, the forested areas have a reddish tint. Finally, the green areas seen at the southern tip of both the Ammersee and the Pilsensee lakes indicate a marshy area. Spaceborne Imaging Radar-C and X-Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR

    Polarized protons are accelerated up to 24.3 GeV in the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory (BNL). To accelerate the beam with preserving the polarization, two different types of helical dipole partial Siberian snake have been installed to the AGS. One is a superconducting magnet (Cold Snake, CSNK), and the other is a normal conducting one (Warm Snake, WSNK). With these snake magnets, the polarization at the AGS extraction achieved 65%. However, the AGS has spin mismatches at the injection and extraction. This description shows calculated results to have better spin matching with using two or three snakes.

    In the present study, Ag/Ag2SO4 hybrid photocatalysts were obtained via a facile redox-precipitation reaction approach by using Ag@Ag3PO4 nanocomposite as the precursor and KMnO4 as the oxidant. Multiple techniques, such as X-ray diffraction pattern (XRD), transmission electron microscope (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spectroscopy (DRS) and Brunauer-Emmett-Teller (BET), photocurrent and electrochemical impedance spectroscopy (EIS), were applied to investigate the structures, morphologies, optical, and electronic properties of as-prepared samples. The photocatalytic activities were evaluated by photodegradation of organic rhodamine B (RhB) and methyl orange (MO) under visible light irradiation. It was found that pure Ag2SO4 can partially transform into metallic Ag during the photocatalytic degradation of organic pollutants, but the Ag/Ag2SO4 hybrids can maintain its structure stability and show enhanced visible light photocatalytic activity because of the surface plasma resonance effect of the metallic Ag.

    Abstract Objective We aimed to quantify progress towards measles elimination in Germany from 2007 to 2011 and to estimate any potential underreporting over this period. Methods We determined the annual incidence of notified cases of measles – for each year – in northern, western, eastern and southern Germany and across the whole country. We then used measles-related health insurance claims to estimate the corresponding incidence. Findings In each year between 2007 and 2011, there were 6.9–19.6 (mean: 10.8) notified cases of measles per million population. Incidence decreased with age and showed geographical variation, with highest mean incidence – 20.3 cases per million – in southern Germany. Over the study period, incidence decreased by 10% (incidence rate ratio, IRR: 0.90; 95% confidence interval, CI: 0.85–0.95) per year in western Germany but increased by 77% (IRR: 1.77; 95% CI: 1.62–1.93) per year in eastern Germany. Although the estimated incidence of measles based on insurance claims showed similar trends, these estimates were 2.0- to 4.8-fold higher than the incidence of notified cases. Comparisons between the data sets indicated that the underreporting increased with age and was generally less in years when measles incidence was high than in low-incidence years. Conclusion Germany is still far from achieving measles elimination. There is substantial regional variation in measles epidemiology and, therefore, a need for region-specific interventions. Our analysis indicates underreporting in the routine surveillance system between 2007 and 2011, especially among adults. PMID:25378728

    We present the synthesis and visible-light-induced catalytic activity of Ag2S-coupled TiO2 nanoparticles (NPs) and TiO2 nanowires (NWs). Through a simple wet chemical process from a mixture of peroxo titanic acid (PTA) solution, thiourea and AgAc, a composite of Ag2S NPs and TiO2 NPs with sizes of less than 7 nm was formed. When the NP composite was further treated with NaOH solution followed by annealing at ambient conditions, a new nanocomposite material comprising Ag2S NPs on TiO2 NWs was created. Due to the coupling with such a low bandgap material as Ag2S, the TiO2 nanocomposites could have a visible-light absorption capability much higher than that of pure TiO2. As a result, the synthesized Ag2S/TiO2 nanocomposites exhibited much higher catalytic efficiency for the decomposition of methyl orange than commercial TiO2 (Degussa P25, Germany) under visible light.

    Silver nanoparticles (Ag NPs) have been used in numerous consumer products and may enter the soil through the land application of biosolids. However, little is known about the relationship between Ag NP exposure and their bioavailability for soil organisms. This study aims at comparing the uptake and elimination kinetics of Ag upon exposures to different Ag forms (NPs and ionic Ag (as AgNO3)) in the isopod Porcellionides pruinosus. Isopods were exposed to contaminated Lufa 2.2 soil or alder leaves as food. Uptake and elimination rate constants for soil exposure did not significantly differ between Ag NPs and ionic Ag at 30 and 60 mg Ag/kg. For dietary exposure, the uptake rate constant was up to 5 times higher for Ag NPs than for AgNO3, but this was related to feeding activity and exposure concentrations, while no difference in the elimination rate constants was found. When comparing both routes, dietary exposure resulted in lower Ag uptake rate constants but elimination rate constants did not differ. A fast Ag uptake was observed from both routes and most of the Ag taken up seemed not to be eliminated. Synchrotron X-ray fluorescence showed Ag in the S-cells of the hepatopancreas, thus supporting the observations from the kinetic experiment (i.e. low elimination). In addition, our results show that isopods have an extremely high Ag accumulation capacity, suggesting the presence of an efficient Ag storage compartment.

    Well-defined Ag(5) and Ag(6) dodecanethiol/tetrabutyl ammonium-protected clusters were prepared by a one-pot electrochemical method. Ag clusters show bright and photostable emissions. The presence of a dual capping renders the silver clusters soluble in both organic and aqueous solvents.
