  8. Sexing Berlin?

    Science.gov (United States)

    Dahlke, Birgit

    2011-01-01

    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.

    Full Text Available A otimização de um programa de controle de plantas daninhas depende da previsão precoce e confiável do impacto destas sobre o rendimento da cultura. Este trabalho teve por objetivos avaliar os efeitos de cultivares e de arranjos de plantas na perda de rendimento de grãos em arroz irrigado e identificar a variável explicativa que proporcione melhor ajuste ao modelo testado. Foram conduzidos dois experimentos em campo, na estação estival de crescimento 2000/01. Os tratamentos constaram de três cultivares de arroz (BRS-38 Ligeirinho, IRGA 417 e BR-IRGA 409, dois espaçamentos entre linhas (15 e 25 cm e populações (dez e seis níveis para o primeiro e segundo experimentos, respectivamente do cultivar de arroz EEA 406, simulando infestação de arroz-vermelho. Os dados foram analisados utilizando-se o modelo de regressão não-linear da hipérbole retangular, ajustado de modo independente para os três fatores estudados. Os resultados do primeiro experimento foram utilizados para avaliar o ajuste dos dados ao modelo e os do segundo para validar o modelo obtido no primeiro experimento. O cultivar IRGA 417 apresentou maior habilidade competitiva com o cultivar simulador de arroz-vermelho do que os outros dois. A redução no espaçamento entre linhas aumentou a habilidade competitiva dos cultivares de arroz em relação ao cultivar concorrente. O modelo da hipérbole retangular foi apropriado para estimar perdas de rendimento de grãos de arroz irrigado por interferência de plantas concorrentes. A variável explicativa área foliar do cultivar EEA 406, em geral, apresentou equivalência à população de plantas como variável independente no modelo matemático testado.The optimization of a weed control program depends on early and reliable prediction of the impact of weeds on crop yield. This research aimed to evaluate the effects of rice cultivars and plant arrangements on flooded rice grain yield loss and to identify the explicative

    Con ocasión de un estudio de revisión que hemos llevado a cabo recientemente sobre la tuberculosis osteoarticular, *** se ha apreciado un cambio notable en las características y manifestaciones de esta enfermedad.

    Hemos sido testigos del comportamiento de la tuberculosis en los últimos 40 años. Realizamos la tesis profesional en el Hospital de niños de la Misericordia de Bogotá en el año 1950 (86, basada en el análisis de más de 300 enfermos de Mal de Pott tratados con pobres resultados en esa institución en la época prequimioterápica. Efectuamos estudios de control del tratamiento quirúrgico de esa afección en el Hospital Infantil Lorencita Villegas de Santos y publicamos sus resultados en los años 1975,1980 Y1987 (85-87-88. Los pacientes correspondientes a estas nuevas series, ya en la época de la quimioterapia moderna, presentaban un mejor pronóstico vital y funcional. Cuadro 1A.

    En el decenio 1978-1988 asistimos al descenso espectacular de la frecuencia de tuberculosis osteoarticular en las salas de nuestros hospitales. Posteriormente hemos sido igualmente testigos de su lenta y progresiva reaparición.

    El estudio actual nos ha mostrado profundos cambios, como ya se ha dicho, en el comportamiento de la entidad, por lo que estamos de acuerdo en denominarla: La tuberculosis, una enfermedad modificada, diferente a la que hasta hace un década parecía derrotada, vencida por las nuevas drogas y las recientes técnicas quirúrgicas.

    La actual es una enfermedad diferente que ha tomado una fuerza avasalladora que amenaza con volverse resistente al tratamiento específico y dar lugar a una pandemia de incalculables proporciones y de terribles consecuencias para la humanidad.

    El objeto de publicar este estudio es recordar a nuestros colegas, en especial a aquellos de las nuevas promociones que quizás no han tenido la oportunidad de estar en contacto con pacientes de tuberculosis osteoarticular, de

    Full Text Available O presente trabalho tem por finalidade comparar as diferenças de retenção de uma resina composta modificada por poliácido (Variglass V.L.C., utilizada como selante oclusal, quando aplicada por dentista, THD e graduando em Odontologia. Foram seladas as superfícies oclusais de 370 primeiros molares permanentes superiores de crianças entre 6 e 8 anos de idade provenientes de escolas públicas do município de Piracicaba. As avaliações clínicas foram realizadas após seis e oito meses da aplicação do selante. Aos seis meses, verificou-se que 78,42% dos selantes clinicamente aceitáveis permaneceram retidos sobre a superfície oclusal. O índice de perdas totais corresponderam a 10,20% do total de selantes aplicados. O melhor índice de retenção total foi obtido quando aplicado por graduando. Aos 12 meses, houve um aumento do número de selantes perdidos (43,79% e conseqüente decréscimo do número de selantes totalmente retidos (18,96%, não havendo diferenças significativas de retenção do selante quando aplicado por dentista, THD e graduando. Nos casos de perdas totais do selante, não se constatou presença de lesão cariosa.The aim of this work is to evaluate the differences of clinical retention of a polyacid-modified resin composite (Variglass V.L.C., used as an occlusal sealant, when applied by dentist, dental hygienist and undergraduate in Dentistry.

Foram realizadas as análises de acidez total titulável (ATT, sólidos solúveis totais (SST, pH, líquido drenado (LD, pectina total (PT, pectina solúvel (PS, firmeza e determinou-se a atividade das enzimas polifenoloxidase (PFO e poligalacturonase (PG da polpa dos frutos, a cada 2 dias. Os tratamentos utilizados foram: atmosferas modificadas com a injeção de 5% de O2 e 5% de CO2, com 2% de O2 e 10% de CO2 e o Controle (atmosfera modificada passivamente. As atmosferas modificadas ativas apresentaram ação injuriosa sobre os tecidos do abacaxi minimamente processado, estimulando a atividade da PFO. O uso de atmosferas modificadas proporcionou menor atividade da PG e, conseqüentemente, menor solubilização de substâncias pécticas. O abacaxi cv. Smooth Cayenne, minimamente processado, apresentou uma vida útil de 6 dias, pois, embora suas principais características físicas e físico-químicas não tenham sido comprometidas, as alterações químicas e bioquímicas não permitiram que o produto atingisse os 8 dias de armazenamento previstos.

Se llevaron a cabo análisis mediante espectroscopia de impedancia electroquímica y curvas de polarización potencio-dinámicas (Tafel. Adicionalmente, se determinó la microestructura en las zonas del cordón de soldadura a través de metalografía óptica. Finalmente, se analizaron los productos de corrosión formados en la superficie de las muestras por medio del microscopio electrónico de barrido (SEM equipado con el analizador químico por EDS. Se observó que una relación de velocidad de avance/velocidad de rotación mayor produce menor velocidad de corrosión y con ello mayor resistencia a la corrosión en medios salinos, al parecer relacionados con el gran tamaño de grano en la zona agitada, que corresponde a más entrada de calor.The corrosion behavior of AZ31B magnesium alloy modified by friction stir processing (FSP was studied in simulated marine environment, in order to determine the effect of process variables rotation speed and travel speed. The corrosion analysis was carried upon by means of electrochemical impedance spectroscopy and potentiodynamic polarization curves (Tafel, metallographic analysis of the welded zones was done by optical microscopy and the chemical analysis of the corrosion products were done by using scanning electron microscope (SEM, equipped with EDS analyzer. It was observed that the increase of the rate rotation speed/travel speed of the process produces a decrease in the corrosion rate and the corresponding increase of the corrosion resistance in marine environment, apparently related to the higher grain size found in the stir zone, corresponding to a higher heat input.

    Full Text Available The purpose of this in vitro study was to compare the marginal leakage in primary molars restored with 2 polyacid-modified composite resins (Dyract AP - Dentsply and F2000 - 3M and a composite resin (Filtek Z250 - 3M as control. First and second primary molars were used for preparation of cavities on the proximal surfaces, with extension of the gingival margin to the cementoenamel junction. Restorations were accomplished after total etching and application of the respective adhesive system, and were divided into groups according to the restorative system and the number of adhesive layers used. The teeth were stored in distilled water for 7 days, followed by thermocycling with 500 cycles at 5ºC - 55ºC, with one minute in each bath. Thereafter, teeth were prepared for immersion in 0.5% methylene blue solution for four hours. The teeth were sectioned in mesiodistal direction for assessment of dye penetration. According to the results of the Kruskal-Wallis test, the three restorative materials employed did not completely avoid marginal leakage at the gingival margin of primary molars. The marginal leakage of PMCR F2000 (4.06 and 3.95 displayed to be higher than the marginal leakage observed for the materials Dyract AP (2.7 and 2.55 and Filtek Z250 (2.25 and 2.43. The number of adhesive layers did not influence the degree of leakage of the three materials.O estudo in vitro avaliou a infiltração marginal em molares decíduos restaurados com três materiais resinosos: as resinas compostas modificadas por poliácidos (Dyract AP - Dentsply e F2000 - 3M e uma resina composta (Filtek Z 250 como grupo controle.

    2017-01-01

    This paper draws on Lefebvre’s rhythmanalysis to investigate the multiple rhythms of the Berlin Marathon, exemplifying and expanding understandings about the rhythms of places and mobilities. First, we discuss how isorhythmic order is imposed on the city and event by race organizers. Secondly, we...... show that a marathon depends upon the preparatory training or ‘dressage’ performed by the thousands who have made themselves ‘race-ready’. Thirdly, we explore the changing individual and collective rhythms that continuously emerge according to contingencies and stages of the race to compose...

    êmica do ventrículo esquerdo. O principal questionamento acerca desse procedimento é a capacidade de fornecimento de fluxo sanguíneo adequado para o miocárdio isquêmico. OBJETIVOS: Avaliar os resultados angiográficos do procedimento de Vineberg pela técnica de Vineberg modificada por Lobo Filho e a morbi-mortalidade no pós-operatório imediato (POI, bem como analisar o fluxo na artéria torácica interna esquerda (ATIE implantada, em repouso e estresse. MÉTODO: De setembro de 1999 a abril 2002, em nosso serviço, oito pacientes foram operados pela técnica supracitada, na qual a introdução da artéria torácica interna na intimidade da musculatura do ventrículo esquerdo foi realizada com auxílio de um "kit" destinado à introdução de marcapassos cardíacos endocárdicos definitivos por punção da veia subclávia. Após seis meses, os pacientes foram estudados angiograficamente e submetidos ao ecodoppler da ATIE implantada. Para estudo do fluxo da ATIE pelo ecodoppler, constituímos dois grupos: "Grupo Vineberg", composto pelos oito pacientes citados; e o "Grupo Controle", composto por vinte pacientes, nos quais a ATIE foi utilizada para revascularizar diretamente a artéria interventricular anterior. O estudo angiográfico demonstrou perviabilidade de todos os enxertos em ambos os grupos. No estudo pelo ecodoppler, foram realizadas medidas de débito e velocidade de fluxo no enxerto. A análise dos dados obtidos foi feita pelo teste-T para amostras pareadas e não pareadas. RESULTADOS: Não houve óbitos ou complicações no POI. O estudo angiográfico demonstrou perviabilidade em 100% dos casos. O débito total observado foi cerca de 55% daquele encontrado no Grupo Controle. Em ambos os grupos, o débito total aumentou do repouso para o estresse. CONCLUSÃO: A técnica de Vineberg modificada por Lobo Filho pode ser utilizada com baixas taxas de morbi-mortalidade, alto índice de perviabilidade, oferecendo fluxo sanguíneo significativo em repouso e sob

    Full Text Available El presente trabajo evaluó en laboratorio, la resistencia mecánica bajo carga monotónica, el módulo resiliente y la resistencia a la deformación permanente que experimenta una mezcla asfáltica cuando se modifica con un desecho de policloruro de vinilo (PVC por vía húmeda. Adicionalmente, fue evaluada durante 21 meses, la influencia del medio ambiente de la ciudad de Bogotá D.C. sobre las propiedades mecánicas de la mezcla modificada. De los resultados obtenidos se concluye que la resistencia mecánica de la mezcla asfáltica modificada es superior en comparación con la convencional. La tendencia general de las mezclas con el tiempo de exposición al medio ambiente de Bogotá D.C. es experimentar un aumento en los valores de rigidez debido principalmente a procesos de endurecimiento por envejecimiento del ligante asfáltico. Sin embargo, para el caso de las mezclas fabricadas con CA 60-70 y modificadas con PVC en los primeros 15 meses de exposición, la rigidez disminuye por efecto de micro-fisuración térmica.

    2015-01-01

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

    Full Text Available Resumo O polietileno de baixa densidade (PEBD é um dos polímeros mais usados atualmente, e a grande quantidade desse polímero produzida resulta em toneladas de resíduos, que necessitam ser tratados. Neste trabalho foi realizada a pirólise termocatalítica do PEBD usando como catalisador a argila vermiculita modificada, como alternativa para o tratamento dos resíduos. A argila foi tratada com solução de ácido nítrico a diferentes concentrações e calcinada a 400 °C. Os materiais foram caracterizados por técnicas de difratometria de raios X, termogravimetria, adsorção de nitrogênio e espectroscopia de energia dispersiva. A pirólise térmica e termocatalítica foi realizada em um micro reator acoplado com GC/MS, a 500 °C. O intuito da pirólise de resíduos poliméricos é a obtenção de hidrocarbonetos leves (C<16, que possam ser empregados na indústria química e petroquímica, através de quebras na cadeia polimérica. Os resultados foram satisfatórios, com aumento no rendimento para hidrocarbonetos leves ao empregar os catalisadores chegando a 71,4% de produtos com C<16, enquanto a pirólise térmica resultou apenas de 25,8%.

Median sternotomy has been used occasionally for right subclavian-pulmonary artery anastomosis with certain advantages over thoracotomy. In this series, 10 patients were submitted to systemic-pulmonary modified Blalock-Taussig shunts by median sternotomy as the first choice. There have been no technical difficulties. The grafts were anastomosed to the right subclavian artery or brachiocephalic trunk. The right pulmonary artery was preferred, but when infeasible, this side of the shunt was made to the pulmonary trunk or left pulmonary artery.

  13. Radiotherapy of benign diseases in Berlin (West)

    Saller, A.

    1979-01-01

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

Dado que los mejores resultados se obtuvieron utilizando Cr-ZSM-5, estos materiales se estudiaron evaluando el efecto del tiempo de reacción, la masa de catalizador, la relación molar estireno/hidroperóxido, la naturaleza del solvente y la temperatura de reacción. Los mejores resultados de las condiciones evaluadas se obtuvieron trabajando con una relación molar sustrato/oxidante de 0,45 y utilizando acetonitrilo como solvente, dado su carácter aprótico y de mayor polaridad de los solventes evaluados (acetonitrilo, acetona, 2-butanol y 2-propanol. El aumento en la temperatura de reacción mostró un incremento en la conversión de estireno, el cual se desaceleró al superar los 60 oC por descomposición térmica del peróxido de hidrógeno.

    Conclusiones: La ultrafiltración modificada puede beneficiar a los pacientes pediátricos no neonatales con cardiopatía congénita operados con bomba porque es capaz de disminuir la concentración sérica de IL-6, IL-10 y lactato post-CEC. Adicionalmente, puede ayudar a filtrar C4d y a remover el exceso de líquido que promovería una mayor hemoconcentración, por lo que se recomienda su uso rutinario cuando las condiciones hemodinámicas lo permitan.

    Full Text Available Resumen: Introducción y objetivos: La apendicitis aguda es la primera causa de las urgencias quirúrgicas. Permanece como un diagnóstico difícil de establecer, particularmente entre jóvenes, ancianos y mujeres en edad reproductiva, en los cuales una serie de condiciones inflamatorias pueden presentar síntomas y signos similares a los de la apendicitis aguda. Diversos sistemas de puntuación se han creado con el fin de incrementar la certeza diagnóstica; estos son baratos, no invasivos y fáciles de usar o reproducir. La escala de Alvarado modificada es probablemente la más difundida y de mayor aceptación en los servicios de urgencias del mundo. Por otro lado, la escala RIPASA fue elaborada en 2010 con mejor sensibilidad y especificidad. En México se encuentran pocos estudios que comparen los diversos sistemas de puntuación en apendicitis. El objetivo es comparar la escala de Alvarado modificada y la escala RIPASA para el diagnóstico de pacientes con dolor abdominal y sospecha de apendicitis aguda. Material y métodos: Se realizó un estudio observacional, analítico y prolectivo, de julio de 2012 a febrero 2014 en el Hospital Universitario de Puebla. Las encuestas en proceso de evaluación fueron aplicadas a los pacientes con sospecha clínica de apendicitis. Resultados: Escala de RIPASA: curva ROC/PC 8.5 (área 0.595, sensibilidad (93.3%, especificidad (8.3%, VPP (91.8%, VPN (10.1%. Escala de Alvarado modificada: Curva ROC/PC 6 (área 0.719, sensibilidad (75%, especificidad (41.6%, VPP (93.7%, VPN (12.5%.

    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

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

Adicionalmente, fue evaluada durante dos años, la influencia del medio ambiente de la ciudad de Bogotá D.C., sobre las propiedades mecánicas de la mezcla modificada. Se concluye que la resistencia mecánica de la mezcla asfáltica modificada incrementa en comparación con la convencional. La tendencia general de las mezclas con el tiempo de exposición al medio ambiente de Bogotá D.C., es experimentar un aumento en los valores de rigidez debido principalmente a procesos de endurecimiento por envejecimiento del ligante asfáltico. Sin embargo, para el caso de las mezclas modificadas y fabricadas con CA 60-70 en los primeros cinco meses de exposición, la rigidez disminuye.The strength under monotonic load, resilient modulus and rutting were evaluated on a hot-mix asphalt (HMAmodified with a natural sphaltite. Additionally, the influence of the environmental conditions of BogotáD.C., was evaluated during two years on the mechanical properties of a modified asphalt mixture. The results show that the mechanical properties evaluated were better for the HMA mixes modified in compared with those with neat asphalts. The asphaltite produces higher mechanical resistance in HMA. The general tendency of the mixtures is increase the modulus with time due to aging of the asphalt cement. However, modified mixtures with AC 60- 70, decrease in stiffness during the first months.

Verificou-se que os frutos submetidos a embalagem de PEBD apresentaram as menores perdas de massa fresca quando comparados aos demais. Da mesma forma, os frutos embalados na presença do adsorvedor de etileno obtiveram a melhor manutenção na coloração da casca, atraso temporal, do pico climatérico, assim como o retardamento na degradação do amido, os menores incrementos de sólidos solúveis e acidez titulável, as menores concentrações de etileno nos interiores das embalagens e atraso temporal e a diminuição da atividade enzimática. Isso, possivelmente, proporcionou os maiores teores de pectina total e solúvel ao final do período experimental. A combinação do uso da embalagem de PEBD com o sachê de permanganato de potássio (KMnO4 resultou no retardamento do processo de maturação dos frutos de banana 'Prata-Anã', quando armazenada a 12 ºC.

    Dahlhausen, Jens; Rötzer, Thomas; Biber, Peter; Uhl, Enno; Pretzsch, Hans

    2018-05-01

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

    Full Text Available Researching the developments of present political economy must necessarily include investigating the tools of contemporary border regime. These are used for surveillance and control of populations in order to create new divisions of labour and enable extraction of rent by using peoples’ bodies. The article focuses on emergency shelters in Berlin, that is, on their function and ways in which the asylum seekers accommodated there spontaneously struggle against them. The research was done as a militant and cooperative work of the network Lager Mobilisation Network in Berlin’s district Wedding, which builds connections with people housed in the sports halls in the mentioned district. The author underlines that exhausting the aslyum seekers psychically is one of the strategies for filtering the ‘unwanted’ from the ‘wanted’, that is the ones that are interesting for the labour market. At the same time, the restriction of movement and limited access to civil rights confine asylum seekers in emergency shelters run by private companies, which seek profits on their account. Far from claiming that non-profit companies have a ‘better’ shelter administration, since the boundaries between them and profit-oriented companies are often blurred, the author rather speaks of new forms of anticolonial struggles by the people living inside. He understands these struggles as the struggles against the contemporary border regime in Germany and the EU and as a potential for building an inclusive society.

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

  1. Literature in focus: A Berlin Romance

    CERN Multimedia

    2005-01-01

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

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

    Directory of Open Access Journals (Sweden)

    Steffen H. Hantke

    2006-06-01

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

    Full Text Available Neste trabalho, foi avaliada a capacidade de adsorção de zeólitas modificadas, CaX e MgX, em contato com uma solução do subproduto do processo de extração de esteviosídeo, um adoçante extraído das folhas de Stevia rebaudiana. Os efeitos do processo de adsorção na estrutura zeolítica foram avaliados por meio de diversas técnicas de caracterização. As análises térmicas mostraram que os compostos adsorvidos sofrem pequenas mudanças estruturais sob aquecimento. A partir da espectroscopia ao infravermelho, foi verificado que o processo de adsorção não modifica a estrutura da zeólita. As medidas de área superficial e volume de poros indicaram que a adsorção ocorre preferencialmente na superfície externa e nos mesoporos. Finalmente, os resultados de acidez indicaram que a adsorção dos compostos orgânicos coloridos ocorre principalmente nos cátions de compensação.

  7. Risk of the research reactor BER II in Berlin

    International Nuclear Information System (INIS)

    Paulitz, Henrik; Hoevener, Barbara; Rosen, Alex

    2015-01-01

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

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

    International Nuclear Information System (INIS)

    Schake, K.

    1994-01-01

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

    2012-04-01

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

    extras a la homeostasis cardiovascular en la presencia del síndrome coronario aguda (SCA OBJETIVO: Investigar si un diagnóstico clínico estandarizado de SAOS, en pacientes con SCA, predice el riesgo de eventos cardiovasculares durante la hospitalización. MÉTODOS: En un estudio de cohorte prospectivo, un grupo de 200 pacientes con diagnóstico de SCA elecido entre Septiembre de 2005 y Noviembre de 2007, fueron estratificados por el Cuestionario de Berlín (CB para el riesgo de SAOS (alto o bajo riesgo. Se probó si el subgrupo de alto riesgo para SAOS presenta mayor tendencia a eventos cardiovasculares. El endpoint primario evaluado fue un desenlace conformado por muerte cardiovascular, eventos cardíacos isquémicos recurrentes, edema pulmonar agudo y accidente vascular cerebral durante la hospitalización. RESULTADOS: Noventa y cuatro (47% de los pacientes identificados por el CB presentaban sospecha de SAOS. Alto riesgo para SAOS estaba asociado con una mortalidad más elevada, aunque sin diferencia estadística (4,25% vs 0,94%; p=0,189, pero con una estadísticamente significativa mayor incidencia de desenlace conformada por eventos cardiovasculares (18,08% vs 6,6%; p=0,016.

    The author presents a case study from the view of economic and architectural history, i.e. the history and development of the Berlin utility, Berliner Elektrizitaetswerke. It is shown that planning, design and construction were not the result of a dialogue between the architect and the utility but that economic, political and cultural goals of policy and public administration had to be integrated as well. The architecture of the industrial buildings therefore should be viewed as part of the community relations in general, i.e. as an element of the interaction between private, state and civilian society interests.

    Full Text Available Se estudió la modificación de una arcilla colombiana tipo montmorillonita con un biopolímero policatiónico -quitosano-, y se evaluó el efecto del peso molecular del modificante en la efectividad del tratamiento de modificación. Como material de partida se empleó una arcilla montmorillonítica sódica la cual se sometió a un procedimiento de modificación desarrollado para tal fin, empleando diferentes concentraciones de quitosano de bajo y alto peso molecular. Las muestras de arcilla modificada fueron analizadas mediante Difracción de Rayos X, Espectroscopía de Infrarrojo con Transformada de Fourier (FTIR, y Análisis Termogravimétrico (TGA con el fin de identificar los posibles efectos del tratamiento de modificación sobre la estructura de la arcilla. Los resultados mostraron una relación directa entre el incremento de la distancia interlaminar de la arcilla modifi cada y la concentración de quitosano, encontrándose un incremento máximo de 1,559 nm para la relación 2:1 en peso de quitosano de bajo peso molecular y arcilla. En general, se detectó una mayor separación interlaminar en la arcilla al emplear quitosano de bajo peso molecular como modificador, comparado con el quitosano de alto peso molecular, aunque en los dos casos se observó una integración efectiva del agente modificador a la estructura de la arcilla. El análisis IR de la arcilla modificada evidenció la presencia en la estructura de grupos CH, NH3+, CH y NH , provenientes del quitosano, mientras el análisis TG sugirió un cierto grado de hidrofobicidad asociada a la presencia de quitosano, siendo estos aspectos de gran importancia para la aplicación de estos materiales como refuerzos de películas poliméricas biodegradables.

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

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

    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.

    Full Text Available La disponibilidad atún rojo fresco, entero y rebanado, como todo producto pesquero fresco está restringida para los consumidores en zonas distantes a los centros de producción por su estabilidad limitada en el almacenamiento. Por ello la industria pesquera en general, en la época de mayor producción, recurre a la congelación para conservar el excedente de producción, y al empacado para protegerlo del ambiente frío y seco del congelador, evitar su deshidratación y “quemaduras por frío”. El surgimiento del Empacado en Atmósfera Modificada como alternativa para incrementar la vida útil de productos alimenticios despertó la inquietud de evaluar la estabilidad de rebanadas de lomo de atún rojo (Thunnus sp. fresco, congeladas y empacadas con 100 % de CO2 durante su almacenamiento a las temperaturas convencionales para su distribución y venta, -10 y -18 ºC, evaluando la estabilidad química, física, microbiológica y sensorial de las rebanadas de lomo de atún rojo durante ≈ 4 meses de almacenamiento congelado. El 50 % de las rebanadas se congeló a -10 ºC (Tratamiento 1 y el 50 % restante a -18 ºC (Tratamiento 2. Las rebanadas congeladas se empacaron individualmente, el 50 % en atmósfera de 100 % de CO2 conservando la proporción 1:2 (rebanada:gas y el 50 % restante en atmósfera de aire. Se almacenaron a la temperatura correspondiente: Tratamiento 1 a -10 ºC y Tratamiento 2 a -18 ºC durante 111 días. Al final del almacenamiento el tratamiento P2 (100 % CO2 ofreció mejor barrera a la pérdida de humedad, favoreció la estabilidad de la fracción de proteínas solubles en solución salina. Las muestras P2 tuvieron mayor aceptación sensorial, fueron las más oscuras y rojas, con menor recuento microbiológico, coincidiendo con el menor contenido en bases volátiles totales. A -10 ºC la atmósfera de 100 % de CO2 no evitó la “quemadura por frío” y los panelistas percibieron el “olor a pescado”.

  5. Investigations on medical film processing in the city of Berlin

    1986-01-01

    An investigation on the methods of film processing in diagnostic radialogy departments can for instance be understood as a mere statistical representation of number and type of processing apparatus and film types, chemical methods and processing time, or it can be done as an attempt to objectively compare the film processing methods by means of a densitometric evaluation of equally exposed films of current usage within a given department. Such a comparative evaluation has been suggested by the diagnostics experts of the Berlin association of medical physicists, who presented their proposals within the course of project planning talks for a planned field test with a phantom for X-ray diagnostics, to be carried out in Berlin.

    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.

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

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

    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.

O filme de BOPP50 mostrou não ser a melhor alternativa para a conservação de camu-camu, pois a sua baixa permeabilidade aos gases ocasionou o acúmulo de CO2 no interior da embalagem, propiciando o processo fermentativo dos frutos após 13 dias de armazenamento. Os atributos pH, sólidos solúveis, acidez titulável, ácido ascórbico e antocianinas não foram afetados pelos tipos de filmes utilizados, mas sim pelos dias de armazenamento. Os resultados mostraram que a utilização do filme de PVC, juntamente com refrigeração, para conservação pós-colheita de camu-camu, foi eficaz na manutenção da firmeza do fruto e na redução de perda de massa, mantendo os frutos comercialmente viáveis por 21 dias, enquanto o controle e os revestidos por BOPP50 se apresentaram inviáveis após 13 dias de armazenamento.

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

    Science.gov (United States)

    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

    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.

    Full Text Available This article explores memory studies from the audience’s perspective, focusing on the perception of Holocaust narratives in two museums in Berlin. This research builds on and contributes to a number of emerging issues on memory studies, tourism perception and museum design: the debate on experiential authenticity, Dark Tourism, as well as the analysis of memory studies from the perspective of the user. The main data facilitating the analysis is based on responses shared on TripAdvisor; the case studies being the Otto Weidt Workshop for the Blind Museum and the Jewish Museum Berlin. The analysis of these museums, focusing on their narratives, design features and comments from visitors, will highlight a potential shift from the traditional object-focused museum, to a phenomenological subject-focused one. It will be argued, then, that the understanding and consumption of authenticity encompasses a very flexible definition, not only based on the nature of the objects exhibited, but on the production of authentic experiences.

A cobertura com braquiarão contribuiu para o controle químico, exercendo supressão das plantas daninhas. A aplicação única de 720 g e.a. ha-1 de glyphosate, independentemente da cobertura vegetal utilizada na entressafra, foi suficiente para o controle adequado de Acanthospermum hispidum, Alternanthera tenella, Amaranthus sp., Bidens pilosa, Xanthium strumarium, Cenchrus echinatus, Digitaria sp. e Eleusine indica, com resultados similares ao tratamento (chlorimuron-ethyl + lactofen + fluazifop-p-buthyl. Comparados à testemunha capinada, os herbicidas testados não afetaram a altura das plantas, massa seca da parte aérea, massa de 100 grãos e a produtividade de grãos. As plantas de soja crescidas sobre os resíduos vegetais de braquiarão e milheto forrageiro apresentaram maior altura, porém, nenhuma outra característica avaliada na cultura foi influenciada pelas coberturas.

Para evitar problemas legales en su comercialización, se deben realizar estudios de libertad de operación. Este estudio se realizó sobre una línea genéticamente modificada (GM de papa (Solanum tuberosum L. derivada de la variedad Pastusa Suprema, que expresa el gene Cry1Ac de Bacillus thuringiensis, desarrollada por la Corporación de Ciencias Biológicas y la Universidad Nacional de Colombia, Sede Medellín. El punto de partida, fue la deconstrucción del producto, cuyo resultado fue la lista de materiales y procesos usados en el desarrollo del producto. Se buscaron en bases de datos nacionales e internacionales de acceso público, las solicitudes de patentes y patentes relacionadas. En el nivel internacional, se encontraron cuatro solicitudes de patentes y dieciocho patentes relacionadas, la mayoría de las cuales, no han sido solicitadas en Colombia. En el nivel nacional, se encontraron 13 solicitudes de patentes, que han caducado, han sido negadas, abandonadas, desistidas, o están en requerimiento. Se encontró que la variedad tiene registro comercial, pero no título de obtentor. También se examinaron documentos de las instituciones participantes, que contuvieran cláusulas sobre propiedad intelectual, y otros documentos de interés, como los acuerdos de transferencia de materiales (ATM. Se concluye que la libertad de operación puede estar afectada más por problemas detectados en los ATM y en la complejidad de los acuerdos interinstitucionales suscritos, que por los derechos de propiedad intelectual.

    Full Text Available A quitosana é um biopolímero produzido a partir da quitina, presente na casca de crustáceos. Atualmente, o estudo de suas propriedades se deve às suas diversas utilizações nas áreas farmacêutica e alimentícia. A quitosana utilizada neste estudo foi quimicamente modificada para tornar-se solúvel em água (quitosana succinilada. Estudou-se a estabilidade de emulsões com d-limoneno para que estes dados sejam úteis na sua posterior utilização como agente de encapsulação de d-limoneno por liofilização. Sua estabilidade foi analisada por espectrofotometria, em diferentes temperaturas, e por cromatografia gasosa associada à técnica da análise do espaço livre, à temperatura ambiente. Sua caracterização foi feita por microscopia óptica. Emulsões de maltodextrina com d-limoneno foram utilizadas para comparação já que maltodextrinas são muito usadas como agentes de encapsulação de aromas. Observou-se boa estabilidade de emulsões de quitosana succinilada com d-limoneno ao longo do tempo e características muito distintas em relação às observadas em emulsões de maltodextrina com d-limoneno. Pode-se concluir neste estudo que emulsões de quitosana succinilada com d-limoneno apresentaram características favoráveis à encapsulação de aromas.Chitosan is a biopolymer derived from chitin, a component of the shells of crustaceans. Recently, special attention has been given to the study of chitosan properties as a consequence of their wide application in pharmaceutical and food areas. In this study, the chitosan used was chemically modified in order to become water soluble (succinyl chitosan. The stability of succinyl chitosan emulsion with d-limonene was studied so that these results could be useful in a subsequent use of succinyl chitosan as a d-limonene encapsulating agent by lyophilization. The stability of the emulsion was analyzed using a spectrophotometer in different temperatures and by the headspace

    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.

Para la evaluación del comportamiento de las mezclas asfálticas convencionales (sin aditivo y modificadas se realizaron ensayos Marshall, módulo dinámico, deformación permanente y resistencia a fatiga. Las mezclas fueron elaboradas con un cemento asfáltico (CA producido en Colombia tipo CA 80-100. Al CA con y sin aditivo se realizaron ensayos de caracterización de asfaltos como penetración y punto de ablandamiento. La modificación de las mezclas se realizó por vía húmeda. Las mezclas modificadas con desecho de PEBD experimentan mayor rigidez (bajo carga monotónica y cíclica y resistencia a la deformación permanente en comparación con las convencionales. Sin embargo la resistencia a fatiga de las mezclas convencionales disminuye cuando se adiciona PEBD al CA. Adicionalmente el CA modificado presenta mayor resistencia a la penetración, mayor punto de ablandamiento y menor susceptibilidad térmica a fluir que el convencional.Laboratory tests were used to evaluate the effect on the mechanical properties of a hot asphalt mix (MDC-2 as per INVIAS, 2007 specifications due to the addition by wet way of a residue of low density polyethylene (LDPE. The strength under monotonic load, resilient modulus, rutting and fatigue strength were evaluated. Asphalt cement (AC AC 80-100 was used from Colombia. The results show that the monotonic and cyclic mechanical strength evaluated were higher for the mixes modified with LDPE compared with mixtures with asphalts without additives. However, the mixes modified with LDPE undergo less fatigue strength. Additionally, characterization tests were conducted on asphalt cement with and without additive. The LDPE produces higher penetration resistance

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

    Schmidt, Erika S

    2010-01-01

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

    2017-03-01

    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.

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

Os frutos embalados apresentaram taxas de perda de massa menores que os sem embalagem (p<0,05. Os frutos tratados com cálcio não apresentaram diferença na taxa de degradação de ácido ascórbico em relação aos não tratados e os frutos embalados com PD-900 apresentaram retenção de ácido ascórbico maior. Após 4 semanas, as goiabas sem embalagem apresentaram-se impróprias para consumo, devido ao murchamento e ataque de fungos, enquanto que as embaladas estavam em bom estado. Após a sexta semana, apenas os frutos embalados com PD-900 sem tratamento com cálcio estavam próprios para consumo. A embalagem de atmosfera modificada reduziu a perda de massa e ácido ascórbico e prolongou a vida-de-prateleira do produto. O emprego de cálcio não afetou as características analisadas.

    2009-01-01

    On October 28, 2009, the Kerntechnische Gesellschaft e.V. (KTG) awarded to Professor Dr. Juergen Knorr its 32 nd honorary membership in recognition of his untiring commitment and his decades of work for the peaceful uses of, and research into, nuclear power in Germany. Between 1992 and 2006 the scientist, now retired, held the Nuclear Power Technology chair at the Technical University of Dresden and, temporarily, also headed the university's Institute for Power Technology at the same time. From 1990, Professor Knorr was a member of the Executive Board of the Kerntechnische Gesellschaft; he was KTG Chairman between 1993 and 2000. At the same time and beyond, until 2005, Professor Knorr was a member also of the Board of the Deutsches Atomforum. At the awarding ceremony in Berlin on October 28, KTG Chairman Dr. Helmut Blaesig welcomed the fact that, on the basis of the coalition agreement of CDU, CSU and FDP, the new federal government 'had clearly recognized the advantages of nuclear power.' It appreciated the safety of German plants and, in addition to the non-polluting characteristics due to CO 2 emissions saved and the security of supply, also the economic benefit of electricity generation from nuclear power. This supported the German economy in a situation which continued to be difficult. In his vote of thanks for the 32 nd honorary membership of KTG, Professor Knorr emphasized what he considered a key expectation of the re-evaluation of nuclear power by the new federal government: Creating framework conditions for a societal consensus that fair competition among conventional, renewable and nuclear power technologies will give rise to an optimum mix enabling sustainable development to be achieved.

    Snake bites are a serious public health problem, especially in subtropical countries. In Brazil, the Ministry of Health notified around 26 000 accidents in 2008. The genus Crotalus (rattlesnakes) accounts for approximately 7% of the total, with a high mortality rate of 72% when untreated with the specific serum, the only effective treatment in case of snake bites. In Brazil, the serum is produced in horses which, despite the large size, have a reduced lifespan due to the high toxicity of the antigen. Ionizing radiation has proven to be an excellent tool for reducing the toxicity of venoms and isolated toxins, resulting in better immunogens for serum production, and contributing to the welfare of serum producing animals. Since the action of gamma radiation on venoms and toxins has not been yet fully clarified from the structural point of view, we proposed in this paper, to characterize two toxins of the species Crotalus durissus terrificus: crotoxin and crotamine. After isolation of the toxins of interest by chromatographic techniques, they were subjected to structural analysis with the application of the following methods: Fluorescence, Circular Dichroism, Differential Calorimetry and Infrared Spectroscopy. These tests showed that both crotamine as crotoxin when subjected to gamma radiation, showed changes in their structural conformation compared with the samples in the native state. Such changes probably occur in the secondary and tertiary structure and may explain the changes on the biological activity of these toxins. (author)

    Zeolite synthesized from coal fly ash was modified with different concentrations (2 and 20 mmol.L{sup -1}) of hexadecyltrimethylammonium bromide (HDTMA-Br). The Non-Modified Zeolite (NMZ) and Surfactant-Modified Zeolites (SMZ) were characterized by X-ray fluorescence spectrometry, X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, thermogravimetric analysis, among others. The SMS presented negative charge probably due to the formation of a partial bilayer of HDTMA on exchangeable active sites on the external surface of NMZ. A decrease in surface area was observed for SMZ as compared to NMZ indicating zeolite surface coverage with HDTMA-Br molecules. The crystalline nature of the zeolite remained intact after adsorption of surfactant and heating for drying. FTIR analysis indicated that there were no significant changes in the structure of the zeolite after adsorption of surfactant. (author)

    In this work was carried out the dyes removal blue vegetable and blue watercolor of aqueous solutions, to 20 C, at different times and using a zeolite mineral of Parral (Chihuahua, Mexico) modified with hexadecyl trimethyl ammonium bromide or dodecyl trimethyl ammonium bromide. The zeolite was characterized before and after of its adaptation with NaCl and later with HDTMABr and DTMABr. For the materials characterization were used the scanning electron microscopy of high vacuum; elementary microanalysis by X-ray spectroscopy of dispersed energy and X-ray diffraction techniques. It was found that the surfactant type absorbed in the zeolite material influences on the adsorption process of the blue dye. Likewise, the chemical structure between the vegetable blue dye and the blue watercolor, determines the efficiency of the color removal of the water, by the zeolites modified with the surfactants.

    Full Text Available Se estudia la adsorción de Cr (VI a partir de biomasa residual: bagazo de palma y cáscaras de ñame, además se estudia la modificación con ácido cítrico de las biomasas. La determinación del metal en solución fue llevada a cabo usando el método de la 1,5-difenilcarbazida. Del análisis FTIR se encontró que los grupos hidroxilo y carbonilo presentes en los adsorbentes son los de mayor contribución al proceso de remoción. Además, la modificación mejora la eficiencia del metal de acuerdo con la isoterma de Langmuir de 13 a 4mg/g para el bagazo de palma, y de 22 a 26mg/g para las cáscaras de ñame. Se establece además una mejora en el proceso al trabajar las biomasas en sistema continuo. De las condiciones óptimas de adsorción se determinó que el pH de 2 y el tamaño de partícula de 1mm son las que más favorecen el proceso, y el modelo de Elovich el que mejor lo describe.

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

    The acute respiratory distress syndrome (ARDS) was re-defined by a panel of experts in Berlin in 2012. Although the Berlin criteria improved upon the validity and reliability of the definition, it did not make diagnosis of ARDS in resource limited settings possible. Mechanical ventilation, arterial blood gas measurements, and chest radiographs are not feasible in many regions of the world. In 2014, we proposed and applied the Kigali modification of the Berlin definition in a hospital in Rwanda. This review synthesizes literature from the last 18 months relevant to the Kigali modification. In the last 18 months, the need for a universally applicable ARDS definition was reinforced by advances in supportive care that can be implemented in resource poor settings. Research demonstrating the variable impact of positive end expiratory pressure on hypoxemia, the validity of using pulse oximetry rather than arterial blood gas to categorize hypoxemia, and the accuracy of lung ultrasound support the use of the Kigali modification of the Berlin definition. Studies directly comparing the Berlin definition to the Kigali modification are needed. Ongoing clinical research on ARDS needs to include low-income countries.

    Berlin's water supplies originate exclusively from groundwater. For sustainable water management, river water is treated by flocculation and filtration and used either for artificial groundwater recharge (rivers Spree and Havel) or for bank filtration (Nordgraben and Lake Tegel). Drinking water chlorination was abandoned in Berlin (West) in 1978, and in Berlin (East) in 1992, following German unification. Chlorine consumption for the purpose of weekly performance checks in the chlorination plants of Berlin's 11 waterworks and occasional chlorination within the pipe system following pipe burst events amounts to 2500 kg per year. Based on the annual water demand of 250 million cubic metres, this is equivalent to 0.01 mg of chlorine per litre. Microbiological monitoring at the 11 waterworks and at 383 sampling points within the pipe system shows CFU at less than 10/1 ml-1 and coliforms and E. coli invariably at 0/100 ml-1. In view of the low AOX content, a multiplication of bacteria within the pipe system can be expected to occur not at all or only to a small extent. Resource protection measures, filter backwashing and pipe system maintenance in observance of the relevant technical rules will continue to ensure that the quality of Berlin's drinking water meets stringent hygiene requirements without chlorination.

O experimento compôs-se de quatro blocos com 40 fileiras de soja, com 20 fileiras de cada cultivar (CD217 e CD219RR. No estádio R8, cinco fileiras, distantes 0, 5, 1, 2, 4 e 8 m da cultivar adjacente, foram colhidas, trilhadas e analisadas quanto à ocorrência de fluxo gênico. Como características marcadoras, foram utilizadas as cores da flor, hipocótilo e pubescência, e a tolerância ao glifosato. As cultivares contrastam quanto às características analisadas, cada uma condicionada por um gene com dois alelos, em interação de dominância completa. Na progênie da cultivar tolerante, a maior taxa de híbridos encontrada foi 0, 27% e, na progênie da cultivar sensível, identificou-se 0, 83%; pela hipótese do efeito diluição, as taxas de hibridação natural populacional seriam 0, 104 e 0, 388%, respectivamente. O fluxo gênico recíproco entre as cultivares CD217 e CD219RR não é o mesmo em ambas as direções. Os estimadores propostos são úteis para determinar a taxa de híbridos em amostras de sementes.

La formulación I respondió a la utilización del ungüento hidrófilo como base, la II a la crema secante y la III a una base emulsionada aceite en agua. Se obtuvo como resultado la no utilización de las formulaciones I y II por la interacción del principio activo con el laurilsulfato de sodio y con el monoestearato de glicerilo, respectivamente. La formulación III resultó muy adecuada desde el punto de vista tecnológico y se le realizaron estudios toxicológicos de irritabilidad dérmica que resultaron favorables, ya que no hubo irritación de las zonas tratadas.ZZ oinment was designed from an active zeolite product which has a marked antimicrobial effect in the treatment of micosis and bacterial affections. Three different formulations were evaluated for the product through physicial-chemical determinations. Formulation I used hidrophil oinment as a base; formulation II used drying cream and Formulation III chose an oil-in-water emulsified base. As a result of this assessment, formulations I and II were not chosen because of the interaction of the active agent with sodium laurylsulphate and with glyceril monostereate respectively. Formulation III turned out to be the most suitable from the technological viewpoint. Toxicological studies were performed on this formulation to observe skin irritability but the results were favourable since there was no trace of irritation in the treated areas.

    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.

    Full Text Available This article gives an overview on Indonesian student activism in Berlin, Germany. Based on documents (published and unpublished, interviews, and conversations with former and current student activists, the paper scrutinizes the trajectory of activism of Indonesian students in the capital of Germany since the 1960s and asks about the evolution of specific student organizations, the issues and topics they tackled, and their media and networking strategies. The article illustrates the activities of the PPI Berlin as a dominant example of Indonesian students’ political activism abroad and the activities of Indonesian Muslim students as a prominent example of religious-based activism which has gained significance since the fall of Suharto. These examples indicate the diversity of Indonesian student activists in Berlin that are nevertheless united in their aspirations to challenge politics back home.

    This study shows how Berlin (n = 35) and Delhi (n = 28) mothers scaffold a common and highly scripted social situation, namely gift giving, and enable cultural learning in 19-month-olds. Using modeling and prompting to encourage appropriate responses, mothers took culture-specific directions during scaffolding that were in line with the broader cultural model as assessed by maternal socialization goals (SGs). Whereas Berlin mothers prioritized autonomous SGs, Delhi mothers emphasized autonomous and relational SGs to similar degrees. During scaffolding, Berlin mothers focused on maximizing positive affect and acknowledging the gift, whereas Delhi mothers prompted toddlers to acknowledge the giver more often. Furthermore, there were differences in toddlers' behavior in line with these culture-specific scripts guiding gift giving. © 2016 The Authors.

    OBJECTIVES Traffic accidents associated with high mortality rate may produce serious problems especially in highways. Obstructive sleep apnea (OSA) has been associated with a high risk for traffic accidents due to excessive daytime sleepiness even in in-city drivers. In the present study, it was aimed to evaluate the rate of OSA symptoms and to identify risk factors associated with traffic accidents in in-city bus drivers. MATERIAL AND METHODS A self-administered questionnaire including demographic and anthropometric features, sleep and work schedules, Berlin questionnaire, Epworth sleepiness score (ESS), and history of traffic accidents was used. RESULTS The questionnaire was conducted for 1400 male bus drivers (mean age, 38.0±6.4 y, body mass index, 27.8±3.9 kg/m2). A total of 1058 (75.6%) drivers had one or more accidents while driving bus. According to the Berlin questionnaire, 176 (12.6%) drivers were found to have high OSA risk and the accident rate was 83.0% in high-risk group, whereas 74.5% of low-risk drivers had accidents (p=0.043). The drivers with a history of traffic accident were older (p=0.030), had higher ESS (p=0.019), and were more in the high-risk OSA group according to the Berlin questionnaire (p=0.015). In multivariate linear regression analysis, traffic accident was associated with only Berlin questionnaire (p=0.015). CONCLUSION The present results support that city bus drivers with high OSA risk according to Berlin questionnaire have increased accident rates. Therefore, we suggest using Berlin questionnaire for screening sleep apnea not only in highway drivers but also in in-city bus drivers. PMID:29755810

    2011-09-01

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

    The incidence of adult respiratory distress syndrome (ARDS) in severe traumatic brain injury (TBI) is poorly reported. Recently, a new definition for ARDS was proposed, the Berlin definition. The percentage of patients represented by TBI in the Berlin criteria study is limited. This study describes the incidence and associated mortality of ARDS in TBI patients. The study was an analysis of the safety of erythropoietin administration and transfusion threshold on the incidence of ARDS in severe TBI patients. Three reviewers independently assessed all patients enrolled in the study for acute lung injury/ARDS using the Berlin and the American-European Consensus Conference (AECC) definitions. A Cox proportional hazards model was used to assess the relationship between ARDS and mortality and 6-month Glasgow Outcome Scale (GOS) score. Two hundred patients were enrolled in the study. Of the patients, 21% (41 of 200) and 26% (52 of 200) developed ARDS using the AECC and Berlin definitions, respectively, with a median time of 3 days (interquartile range, 3) after injury. ARDS by either definition was associated with increased mortality (p = 0.04) but not with differences in functional outcome as measured by the GOS score at 6 months. Adjusted analysis using the Berlin criteria showed an increased mortality associated with ADS (p = 0.01). Severe TBI is associated with an incidence of ARDS ranging from 20% to 25%. The incidence is comparable between the Berlin and AECC definitions. ARDS is associated with increased mortality in severe TBI patients, but further studies are needed to validate these findings.

    The division of Berlin in the aftermath of World War II and the erection of the Wall in 1961 were not only of tremendous political, social and cultural significance, but also had implications for the way in which science was undertaken in this city. For ecologists living and working in the enclosed city part of West Berlin, the lack of accessible countryside motivated them to focus their fieldwork increasingly on urban sites and, thereby, to engage themselves in one of the most significant attempts to develop an ecology of the city.

    During the years 1965-1971 about 95 species of lichens were identified within the district of West Berlin. A few of them were growing on trees; corticolous foliaceous species are present in very reduced numbers, and the surviving individuals do not appear healthy. The majority of the species are found on walls and large rocks or on the ground in pine woods. Even these species are showing signs of diminution. Several species seem to have disappeared since the beginning of the observations. Air pollution is singled out as the cause of the decline of the lichens. Berlin today must be considered a lichen desert. 29 references, 2 figures.

    Full Text Available A utilização de substratos vegetais à base de palha tem vindo a assumir uma importância crescente na cultura de cogumelos sapróbios, principalmente do género Pleurotus. Estes cogumelos são considerados muito interessantes do ponto de vista comercial, não só pelas suas características organolépticas e nutricionais, mas também pela sua fácil adaptação e manutenção, crescimento rápido e relativo baixo custo de cultura. No entanto, por se tratar de alimentos perecíveis, devido sobretudo à sua composição e elevada taxa respiratória, podem apresentar reduzido valor comercial, caso a conservação não seja efectuada nas melhores condições. No sentido de minimizar estas alterações, os cogumelos frescos devem ser submetidos a um processamento mínimo com utilização combinada de embalagem em atmosfera modificada, de forma a manter a qualidade e estabilidade no período de conservação. Neste trabalho foram efectuados ensaios de produção de três espécies do género Pleurotus, cultivadas em palha de trigo, com a finalidade de determinar a espécie mais produtiva e avaliar a qualidade dos mesmos durante a conservação quando processados e embalados em atmosfera modificada. Os resultados permitem concluir que a espécie mais produtiva foi a P. ostreatus, seguida da P. sajor-caju e P. eryngii, tendo sido a P. eryngii a que mostrou maior resistência à degradação no período de conservação estabelecido.The use of substrates straw has been increasing importance in mushroom saprophytic species grown, especially of Pleurotus genus.

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

    On behalf of the Senate Department for Environment of the State of Berlin IFEU Heidelberg and ICU Berlin analysed a climate friendly waste treatment for the 36 most important waste types. The inventory for 2010 showed that the management of the 6.7 million tonnes of waste in the State of Berlin led to a remarkable prevention of greenhouse gas emissions of about -900,000 tonnes of CO{sub 2}-equivalents. Treatment optimisation for half of the waste types and increased source separation of dry recyclables and organics can lead to an additional mitigation of greenhouse gases of about -248,000 tonnes CO{sub 2}-equivalents. The impact of waste management on the global warming potential was determined using the standardised LCA method modified for waste management. A key element of the study was the intensive and constructive exchange with stakeholders. The results were integrated into an action plan based on the findings of the analysis of potentials and optimisation scenarios. For the relevant waste types of municipal origin property specifications were prepared. The specifications include distinct minimum criteria for an optimised treatment to reach the identified waste specific greenhouse gas reductions. The focus of the study was on climate change. A second study will be extended to further important environmental impacts like resource saving. (orig.)

    To investigate whether the incidence of cervical intraepithelial neoplasia (CIN), in particular of high grade CIN, increased in Berlin during the period 1970-1989 and whether the ages of women with CIN had decreased. In the former German Democratic Republic, which had a highly centralized public health system, all gynecologic operations performed on women living in the Mitte district of Berlin were carried out during the period 1970-1989 (when the Berlin Wall fell) in the gynecologic clinic of the Charité Hospital. The incidence of all CIN increased from year to year over the observation period: 0.04% (1970-1971), 0.10% (1980-1981), 0.39% (1988-1989). There was a particularly high increase in the incidence of high grade intraepithelial neoplasms (CIN 3): 0.016% (1970-1971), 0.056% (1980-1981), 0.25% (1988-1989). With a virtually unchanged age distribution for women in the Mitte district of Berlin, the median age of women with CIN 3 decreased significantly from 1970 to 1989, from 39.5 (1970) to 33 (1989) (P < .001). The increase in the incidence of CIN, especially of high grade CIN, as well as the reduction in age for onset of the disease, makes high participation in screening necessary, above all among young women.

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

    2014-10-01

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

    2010-01-01

    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.

    2011-01-01

    In large cities such as Berlin, human mortality rates increase during intense heat waves. Analysis of relevant data from north-eastern Germany revealed that, during the heat waves that occurred between 1990 and 2006, health risks were higher for older people in both rural and urban areas, but that, during the two main heat waves within that 17-year period of time, the highest mortality rates were from the city of Berlin, and in particular from its most densely built-up districts. Adaptation measures will need to be developed, particularly within urban areas, in order to cope with the expected future intensification of heat waves due to global climate change. - Highlights: → Periods of heat stress enhance mortality rates in Berlin and Brandenburg. → Heat-related mortality is an urban as well as a rural problem. → During extreme events highest mortality rates can be found in the city centre. → Mortality rates correlate well with the distribution of sealed surfaces. → Health risks are higher for older than for younger people. - During periods of severe heat stress the pattern of mortality rates in Berlin and Brandenburg was found to correlate well with the distribution of sealed surfaces.

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

    Science.gov (United States)

    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.

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

    Directory of Open Access Journals (Sweden)

    Asaf Leshem

    2013-10-01

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

Duas atmosferas foram aplicadas, variando-se o nível de CO2 em 10 e 15%, reduzindo nos dois casos o O2 a 5%. Após o acondicionamento, a alface foi imediatamente refrigerada. Comparou-se a qualidade da alface com e sem atmosfera modificada durante o armazenamento refrigerado. Monitoraram-se a variação da concentração de O2 e CO2 no interior das embalagens e a vida-útil da alface pela análise sensorial e microbiológica e a variação de sólidos solúveis. A influência da atmosfera modificada no crescimento de microrganismos e na variação de sólidos solúveis não foi relevante. Entretanto, essa tecnologia reduziu as taxas de respiração e, conseqüentemente, minimizou as perdas de qualidade sensorial da alface durante todo o armazenamento.

  3. The Berlin astronomer - Life and works of Johann Elert Bode (1747-1826) (German Title: Der Berliner Astronom - Leben und Werk von Johann Elert Bode (1747-1826) )

    Science.gov (United States)

    Schwemin, Friedhelm

    Johann Elert Bode (1747-1826), long-time director of Berlin Observatory, earned his merits by editing the “Astronomisches Jahrbuch” for many years, for producing a immaculate star atlas, and for writing a series of popular books. Today, astronomers still know the “Titius-Bode law” of planetary distances, which had been publicized by him. The author traces the life of this Hamburg-born scholar. He analyzes his works and tries to determine his place in the history of astronomy. The volume comprises texts of original documents from Bode's life, a bibliography of his works, as well as numerous historical illustrations, often published here for the first time.

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

    For basic and application-oriented research assignments the Helmholtz-Center Berlin (Helmholtz Zentrum Berlin - HZB) runs a research reactor that operates as a source of neutron beams for a wide range of scientific investigations. At the end of the 1980{sup th} the BER II was completed renewed and fitted with new experimental facilities. The BER II is a light water cooled and moderated swimming pool type reactor to be operated at 10 MW thermal power. Six neutron guides deliver cold neutrons from the cold moderator cell to a neutron guide hall adjacent to the experiment hall. With its 24 experimental stations, experimenters at HZB have practically all neutron scattering or neutron radiography techniques at their disposal. (orig.)

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

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

  13. The first international leprosy conference, Berlin, 1897: the politics of segregation.

    Science.gov (United States)

    Pandya, S S

    2004-01-01

    The present paper examines the first attempts to internationalise the problem of leprosy, a subject hitherto overlooked by historians of imperialism and disease. The last decade of the nineteenth century saw many in the civilised countries of the imperialist West gripped by a paranoia about an invasion of leprosy via germ-laden immigrants and returning expatriates who had acquired the infection in leprosy endemic colonial possessions. Such alarmists clamoured for the adoption of vigorous leper segregation policies in such colonies. But the contagiousness of leprosy did not go unquestioned by other westerners. The convocation in Berlin of the first international meeting on leprosy revealed the interplay of differing and sometimes incompatible views about the containment of leprosy by segregation. The roles of officials from several countries, as well as the roles of five protagonists (Albert Ashmead, Jules Goldschmidt, Edvard Ehlers. Armauer Hansen, and Phineas Abraham) in the shaping of the Berlin Conference are here examined.

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

    Zeolites synthesized from fly and bottom ashes and modified with hexadecyltrimethylammonium (HDTMA) were used as adsorbent to remove dyes - Solophenyl Navy (SN) and Solophenyl Turquoise (ST) and their hydrolysed forms Solophenyl Navy Hydrolysed (SNH) and Solophenyl Turquoise Hydrolysed (STH), from simulated textile wastewater. The HDTMA-modified fly zeolite (ZMF) and HDTMA-modified bottom zeolite (ZMB) were characterized by different techniques, as X-ray fluorescence spectrometry, X-ray diffraction and scanning electron microscopy, etc. The ZMF and ZMB presented negative charge probably due to the formation of a partial bilayer of HDTMA on exchangeable active sites on the external surface of unmodified zeolite. Initial dye concentration, contact time and equilibrium adsorption were evaluated. The adsorption kinetic for SN, ST, SNH and STH onto the zeolites followed the pseudo second-order model. The equilibrium time was 20 min for SN and ST and 30 min for SNH and STH, respectively. Langmuir, Freundlich and Temkin models were applied to describe the adsorption isotherms. Adsorption of the dyes were best described by the Langmuir model, with exception to SN/ZPM, SNH/ZPM and SNH/ZLM systems that followed Freundlich model. The maximum adsorption capacities were 3,64; 3,57; 2,91 e 4,93 for SN, ST, SNH e STH by ZLM, respectively and 0,235; 0,492; 1,26 e 1,86 by ZPM, in this order. The best performance for hydrolyzed dyes has been attributed to reduction of the size of dyes molecules during the hydrolysis process. Acute toxicity of the dyes to a different organism were evaluated by different test-organisms. Waterflea, Ceriodaphnia dubia showed EC50 value of 1,25; 54,5; 0,78 and 2,56 mgL{sup -1} for SN, ST, SNH and STH, respectively. The plant Lemna minor showed EC50 values of 18,9; 69,4; 10,9 and 70,9 mgL{sup -1} for SN, ST, SNH and STH, respectively. Midges larvae of Chironomus tepperi showed EC50 values of 119 and 440 mgL{sup -1} for SN and ST, respectively. Regarding the adsorption process, acute effects were substantially reduced after adsorption treatment of aqueous solution with SN and ST by ZMF, as well as their hydrolysed forms, showing no toxicity after removal of 100% of colour. After treatment with ZPM there was an increase of the toxicity, with exception of SHN and STH dyes that do not show toxicity after the treatment. Toxicity Identification Evaluation tests (TIE) were realized in order to identify what substances were causing the observed toxicity for the SN, ST and the leached of ZMF and ZMB. The acute effects were significantly reduced after manipulation with Solid-Phase Extraction (SPE) and Ethylenediaminetetraacetic acid (EDTA) for the leached of ZMB and ZMF. The dyes showed reduced in the toxicity after manipulation with EDTA indicating that the toxicants are mostly cationic metals. (author)

    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. 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. 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. 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.

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

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

    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.

    Allen, L.; Silbergeld, E.

    2016-12-01

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

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

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

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

    Since the late 1950's, a steadily increasing immigrant population in Germany is resulting in a subpopulation of aging immigrants. The German health care system needs to adjust its services-linguistically, culturally, and medically-for this subpopulation of patients. Immigrants make up over 20% of the population in Germany, yet the majority receive inadequate medical care. As many of the labor immigrants of the 1960s and 1970s are in need of hospice and palliative care (HPC), little is known about this specialized care for immigrants. This epidemiological study presents utilization of HPC facilities in Berlin with a focus on different immigrant groups. A validated questionnaire was used to collect data from patients at 34 HPC institutions in Berlin over 20 months. All newly admitted patients were recruited. Anonymized data were coded and analyzed by using SPSS and compared with the population statistics of Berlin. 4118 questionnaires were completed and included in the analysis. At 11.4% the proportion of immigrants accessing HPC was significantly (pimmigrants in Berlin population, 17.7% immigrants in HPC population) and 61-70 years (16,9% vs. 13,1%). The largest ethnic groups are Turks, Russians, and Poles, with a different weighting than in the general population: Turkish immigrants were 24% of all Berlin immigrants, but only 13.6% of the study immigrant population (OR: 0.23, 95%CI: 0.18-0.29, pimmigrants account for 5.6% and 9.2% in the population, but 11.5% and 24.8% in the study population respectively (Russian: OR 0.88, 95%CI: 0.66-1.16; Polish: OR 1.17, 95%CI: 0.97-1.42). Palliative care wards (PC) were used most often (16.7% immigrants of all PC patients); outpatient hospice services were used least often by immigrants (11.4%). Median age at first admission to HPC was younger in immigrants than non-immigrants: 61-70 vs. 71-80, p = 0.03. Immigrants are underrepresented in Berlin´s HPC and immigrants on average make use of care at a younger age than non

    One promising option of the reduction of the emission of greenhouse gases and the promotion of the climate protection is the utilization of electric-powered vehicles. The customer acceptance and practical suitability of electric-powered vehicles are essential factors of success which are investigated within the Berlin field test 'MINI E 1.0 powered by Vattenfall' from the perspective of energy industry, vehicle manufacturer and the science. Beside the hurdles up to the establishment in the mass market, it is shown how the users with aspects specific for electric-powered vehicles interact, and how the controlled loading facilitates the optimal integration of wind power. The comprehensive collection of subjective and objective data as well as detailed information on the conception of the case study complete the contribution under consideration.

    When perinatal medicine emerged as a new medical discipline in the 1960s, Berlin was as one of the world's leading centers. During that time, the city was separated into two parts, each fostering its own health care system. After the destruction of the Berlin Wall, it was possible to speak with the citizens of East Berlin and to access their database systems. This created the singular opportunity to objectively compare the development of perinatal care in both parts of Berlin. Rates of maternal, perinatal, and infant mortality as well as the rate of preterm deliveries were evaluated over time and between East and West Berlin. The timing of introduction of 20 specific perinatal interventions was evaluated across 18 hospitals with more than 500 deliveries (11 in West Berlin and 7 in East Berlin). Interviews were conducted with 100 gynecologists, 100 midwives, and 100 women who had recently delivered their first child from each side of the city regarding their opinions of the importance of these interventions for the quality of perinatal medicine and how they would distribute a budget to improve maternity care. Maternal, perinatal, and infant mortality decreased in both parts of Berlin until 1990 (p Berlin, though the preterm delivery rate was slightly lower in East Berlin compared with West Berlin (p Berlin. In contrast, certain public health measures--such as maternal transport, screening programs for diabetes, and support of breastfeeding--were introduced much earlier in East Berlin. There were significant differences between the beliefs of gynecologists, midwives, and mothers in East and West Berlin. In general, citizens of East Berlin were more enthusiastic about technological medical advances, whereas citizens of West Berlin were more supportive of public health and alternative methods. In addition, there were significant differences between female and male physicians in their beliefs about how to improve health care, regardless of whether they resided in East

    Full Text Available In dieser Untersuchung werden beispielhaft die Lebenswege und Karrieren von Berliner Geowissenschaftlerinnen im Zeitraum von 1906 bis 1945 nachgezeichnet und analysiert. Ähnlich wie an anderen deutschen bzw. westlichen Universitäten, aber im Gegensatz zu Russland, begann die Tätigkeit von Frauen in den Geowissenschaften spät, und das Fach wurde auch relativ selten gewählt, hauptsächlich wegen der zu geringen Berufschancen. Aber die besondere Situation in Berlin mit mehreren sich ergänzenden Institutionen und dem daraus resultierenden breiten Spektrum an geowissenschaftlichen Disziplinen, sowie ausgezeichneten Professoren, ließ dennoch Raum für eine Ausbildung in diesem Bereich und erlaubte, wenn auch in bescheidenem Maße, eine gewisse Karrieremöglichkeit. Während der hier untersuchten 40 Jahre haben weniger als 20 Frauen in den Geowissenschaften und benachbarten Gebieten promoviert. Mehrere dieser Frauen blieben in dem von ihnen gewählten Fach weiterhin aktiv und wurden erfolgreich. Zwei Frauen gelang eine akademische Karriere — eine als Universitätsprofessorin, die auch Schülerinnen hatte. Andere arbeiteten an staatlichen Institutionen, wie z. B. dem Geologischen Landesamt. Wenige Frauen blieben nach ihrer Verheiratung beruflich aktiv, wenn auch nicht offiziell angestellt, sondern als Ehefrauen. Andere arbeiteten als "Ersatz" für die im Kriege stehenden Männer. Einige waren aus persönlichen und politischen Gründen, insbesondere während der NS-Zeit, gezwungen, die Geowissenschaften zu verlassen, konnten aber teilweise auf anderen Gebieten erfolgreich arbeiten. This paper documents the lives and careers of women geoscientists at the Berlin Friedrich-Wilhelms-University from 1906 through 1945. Traditionally, in Germany, women had difficulties to be accepted in geosciences (except for geography/geology teachers, because of strong links between geology and mining, a field dominated clearly by men.

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

    Mechanical circulatory devices are indicated in patients with refractory cardiac failure as a bridge to recovery or to transplantation. Whenever required, transportation while on mechanical support is a challenge and still limited by technical restrictions or distance. We report the first pediatric case of transatlantic air transportation on a Berlin Heart EXCOR ventricular assist device (Berlin Heart, Berlin, Germany) of a 13-yr-old American female who presented in cardiogenic shock with severe systolic dysfunction while vacationing in France. Rapid hemodynamic deterioration occurred despite maximal medical treatment, and she was supported initially with extracorporeal membrane oxygenation converted to a Berlin Heart EXCOR left ventricular assist device. Long-distance air transportation of the patient was accomplished 3 wks after implantation from Marseille, France, to Denver, Colorado. No adverse hemodynamic effects were encountered during the 13.5-hr flight (8770 km). The patient did not recover sufficient cardiac function and underwent successful orthotopic heart transplantation 3 months after the initial event. Our experience suggests that long-distance air transportation of pediatric patients using the Berlin Heart EXCOR mobile unit as a bridge to recovery or transplantation is feasible and appears safe.

    Acute respiratory distress syndrome (ARDS) is a leading cause of mortality in burn patients. Smoke inhalation, pneumonia and inflammation process are the major causes of ARDS in burn patients. The American European Consensus Conference (AECC) definition proposed in 1994 has recently been revised by the Berlin definition. Our objective was to describe the epidemiology of ARDS comparing the Berlin definition with the AECC definition in a retrospective cohort of burn patients. We reviewed admitted burn adult patients for a two year period, and investigated patient who received mechanical ventilation for more than 48 h and in whom pneumonia was diagnosed. 40 patients were analyzed. According to the AECC definition, 11 patients met criteria for ALI (27.5%), and 29 patients for ARDS (72.5%). According to the Berlin definition, all patients met criteria for ARDS: 4 (10%) for a severe ARDS, 25 (62.5%) for a moderate ARDS, 11 (27.5%) for a mild ARDS. Inhalation injury was diagnosed in 10 patients (25%). Categorizing patients with the Berlin definition showed statistically significative difference of mortality within the three groups, but not with the AECC definition. The Berlin definition seems to be more accurate than the AECC definition to assess the severity of ARDS in term of outcome in burn patients. This definition may facilitate prompt recognition of ARDS in burn patients, and promote protective ventilation strategy to a larger number of patients. Copyright © 2014 Elsevier Ltd and ISBI.

    The purpose of this study was to compare the Berlin definition to the American-European Consensus Conference (AECC) definition in determining the prevalence of acute respiratory distress syndrome (ARDS) and associated mortality in the critically ill burn population. Consecutive patients admitted to our institution with burn injury that required mechanical ventilation for more than 24 hours were included for analysis. Included patients (N = 891) were classified by both definitions. The median age, % TBSA burn, and injury severity score (interquartile ranges) were 35 (24-51), 25 (11-45), and 18 (9-26), respectively. Inhalation injury was present in 35.5%. The prevalence of ARDS was 34% using the Berlin definition and 30.5% using the AECC definition (combined acute lung injury and ARDS), with associated mortality rates of 40.9 and 42.9%, respectively. Under the Berlin definition, mortality rose with increased ARDS severity (14.6% no ARDS; 16.7% mild; 44% moderate; and 59.7% severe, P Berlin definition was not different from patients without ARDS (P = .91). The Berlin definition better stratifies ARDS in terms of severity and correctly excludes those with minimal disease previously captured by the AECC.

    Full Text Available Os frutos da pinheira possuem limitações para sua distribuição a mercados distantes, por causa do rápido amadurecimento, que os torna muito macios, de difícil manuseio sem a ocorrência de danos e de conservação extremamente reduzida. O objetivo deste trabalho foi avaliar a influência do filme de policloreto de vinila (PVC, associado às temperaturas de refrigeração, na conservação pós-colheita da pinha. Os frutos foram selecionados, lavados, sanitizados e acondicionados em bandejas de isopor, com, ou sem, envolvimento de película de policloreto de vinila, e conservados a 12 e 25 ºC. Foram avaliados: cor da casca, firmeza, perda de matéria fresca, sólidos solúveis, acidez titulável, açúcares totais e amido. Os frutos conservados a 12 ºC, com policloreto de vinila, mantiveram a coloração verde da casca até o 18º dia, apresentaram menor perda de massa de matéria fresca e firmeza da casca e menor teor de sólidos solúveis e acidez titulável, em relação aos frutos armazenados a 25 ºC. A utilização da embalagem, associada à temperatura de 12 ºC, permite um período seguro de 18 dias de conservação, com adequada manutenção dos atributos físicos e químicos.

    Full Text Available Las bobinas Rogowski son dispositivos sencillos, confiables y versátiles para hacer mediciones de corriente en una amplia gama de aplicaciones que van, desde dispositivos microelectrónicos hasta sistemas de alta potencia en instalaciones industriales. Se construyó una bobina de Rogowski y el circuito de acondicionamiento de la señal para poder hacer mediciones de su respuesta ante estímulos eléctricos y llevar a cabo un análisis cualitativo. Adicionalmente, a partir del modelo matemático de la bobina, se hizo una modificación en la estructura interna de la misma para obtener voltajes de mayor magnitud y facilitar la lectura en instrumentos de medición eléctrica. Estos resultados se compararon con una bobina comercial estándar y las mediciones del voltaje de salida de la bobina Rogowski modificada muestran una señal con menos ruido y de mayor magnitud. Al haber aumentado la relación señal ruido en el sistema, el circuito de integración y amplificación arrojan resultados esperados.

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

    The Verein Jugendheim in Berlin-Charlottenburg was a holding organisation of welfare institutions and of training facilities for members of the caring professions. In 1928 it founded a Soziales Institute that offered various courses for advanced vocational training. In those courses depth psychology - mainly represented by the Adlerians, least by the Jungians and increasingly by the Freudians - had a prominent place. The role of the Freudian school was supported by the fact that two staff members of the Jugendheim (Hildegard Buder-Schenck, Ursula Graf [Laessig]) started their analytic training at that time. The main teachers of psychoanalysis at the Institute were Siegfried Bernfeld, Edith Jacobson and Steffi Bornstein; notes take by a student at one of Jacobson's seminars are documented in this paper. In general, in the psychoanalytic courses there seems to have been a shift from academic teaching of theory to case oriented supervision. The presence of psychoanalysis in the training program of the Jugendheim indicates the beginning of an institutional rapprochement between pedagogy or social work and psychoanalysis in Berlin, analogous to earlier developments in Vienna. The rise of the Nazis put a stop to this promising, yet hitherto completely unknown, chapter of history.

    Full Text Available Little information is available on the influence of temperature on plastic films wrapped okra (Albelmoschus esculentus for their postharvested conservation. This works investigated the influence of the temperature and PVC film on the development of chilling injury and storability from one of the most popular Brazilian cultivar of okra cv. Amarelinho in fruits stored at 5, 10ºC and at 25ºC. Fruits were harvest at commercial maturity stage with length ranging from 8 to 12 cm, and immediately wrapped in PVC over a polystyrene tray and than stored until visible deterioration or wilting symptoms. Lowering the temperature of storage room from 25 to 10 or 5ºC decreased the weight loss in both PVC wrapped and control fruits, with a lower rate at 5ºC. By reducing the temperature to 5 or 10ºC and wrapping the fruits in PVC film, the relative water content of the fruit pericarp was maintained throughout the storage, while at 25ºC the high weight loss was associated with significant reduction of the water content. The development of chilling symptoms was delayed by the presence of PVC film in fruits stored at 5ºC. However, at 10ºC symptoms of pitting were not developed in PVC wrapped or control fruits up to tenth day of storage. The rate of chlorophyll degradation was diminished by reducing the temperature and by wrapping the fruits with PVC film. The appearance of severe chilling symptoms at 5ºC was associated to less chlorophyll in the fruit pericarp on the control as compared to their content in the PVC wrapped fruits.Para o armazenamento do quiabo (Albelmoschus esculentus há poucas informações disponíveis sobre a influência da temperatura e filmes plásticos na conservação pós-colheita desta hortaliça.

    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

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

    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.

    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.

    Full Text Available This paper examines the situation in Cuba after 25 years of the fall of the Berlin Wall. The Cuban political system has prevailed despite predictions foresaw its imminent end since the soviet-like socialism crumbled in East Europe and then in the USSR itself. Although the end of the cold war led to profound adjustments in the international system, the Cuban model remained almost unchanged; however, a Cuban repaired communism emerged in the nineties. Dollarization of the economy and permission for foreign investment affected the ideological purity as the main basis of the system persisted untouched. Nevertheless, since Raul Castro took over power from his brother Fidel in 2006 expectations for reform have increased. In fact, in 2011 the Sixth Congress of the Communist Party was held and some reforms have been implemented ever since. The paper focuses on the scope of those reforms as there are still many open questions about the future of the Cuban society.

According to our results, fitness and physical skills are, at least to a certain extent, socially inherited. The fitness differences found in the different schools can be explained partly by the different social back ground......Health and fitness among children and adolescents is a subject currently receiving public attention. This article focuses on the fitness of German pupils (third and fourth grades) in five schools in Berlin with widely differing social catchment areas as well as children from differing social...

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

    Directory of Open Access Journals (Sweden)

    2015-11-01

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

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

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

  16. The Einstein dossiers science and politics - Einstein's Berlin period with an appendix on Einstein's FBI file

    CERN Document Server

    Grundmann, Siegfried

    2004-01-01

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

    2016-11-01

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

    Full Text Available Regarding the transformations produced by the housing projects for the Olympic Games, the construction and following reuse of the Olympic Villages is an interesting studying matter. During the hundred-year-old history of the modern Olympics the realization of the Olympic Village, which finds reference in the de Coubertin’s writings, and the town planning transformations, to this correlated, have revealed in different ways. The essay mainly concerns the origins of the Olympic Village and the first settlements which characterized the Games in the thirties: Los Angeles 1932 and Berlin 1936. In these two cities, even though with different motivations, politico-economical stimulus and different images, the prototypes of the modern Olympic sport facilities, which find in the village an in the stadium the symbol of the event, were born.

    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).

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

    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.

    Our objective was to revise the definition of acute respiratory distress syndrome (ARDS) using a conceptual model incorporating reliability and validity, and a novel iterative approach with formal evaluation of the definition. The European Society of Intensive Care Medicine identified three chairs with broad expertise in ARDS who selected the participants and created the agenda. After 2 days of consensus discussions a draft definition was developed, which then underwent empiric evaluation followed by consensus revision. The Berlin Definition of ARDS maintains a link to prior definitions with diagnostic criteria of timing, chest imaging, origin of edema, and hypoxemia. Patients may have ARDS if the onset is within 1 week of a known clinical insult or new/worsening respiratory symptoms. For the bilateral opacities on chest radiograph criterion, a reference set of chest radiographs has been developed to enhance inter-observer reliability. The pulmonary artery wedge pressure criterion for hydrostatic edema was removed, and illustrative vignettes were created to guide judgments about the primary cause of respiratory failure. If no risk factor for ARDS is apparent, however, objective evaluation (e.g., echocardiography) is required to help rule out hydrostatic edema. A minimum level of positive end-expiratory pressure and mutually exclusive PaO(2)/FiO(2) thresholds were chosen for the different levels of ARDS severity (mild, moderate, severe) to better categorize patients with different outcomes and potential responses to therapy. This panel addressed some of the limitations of the prior ARDS definition by incorporating current data, physiologic concepts, and clinical trials results to develop the Berlin definition, which should facilitate case recognition and better match treatment options to severity in both research trials and clinical practice.

    In the Centre of Diabetes and Metabolic Disorders of Berlin, G.D.R., a computer-aided care system has been used since 1974, aiming at relieving physicians and medical staff from routine tasks and rendering possible epidemiological research on an unselected diabetes population of a defined area. The basis of the system is the data bank on diabetics (DB), where at present data from approximately 55,000 patients are stored. DB is used as a diabetes register of Berlin. On the basis of standardised criteria of diagnosis and therapy of diabetes mellitus in our dispensary care system, DB facilitates representative epidemiological analyses of the diabetic population, e.g. prevalence, incidence, duration of diabetes, and modes of treatment. The availability of general data on the population or the selection of specified groups of patients serves the management of the care system. Also, it supports the computer-aided recall of type II diabetics, treated either with diet alone or with diet and oral drugs. In this way, the standardised evaluation of treatment strategies in large populations of diabetics is possible on the basis of uniform metabolic criteria (blood glucose plus urinary glucose). The system consists of a main computer in the data processing unit and of personal computers in the diabetes centre which can be used either individually or as terminals to the main computer. During 14 years of experience, the computer-aided out-patient care of type II diabetics has proved efficient in a big-city area with a large population.

An examination of the unpublished correspondence between Henrique da Rocha Lima and Oswaldo Cruz prior to the conference/exhibition reveals the peculiarities of a Brazilian-style event, where the outcome seems to be determined by haphazard incidents rather than by meticulously planned strategies. Their letters can also be read as a narrative celebrating individual qualities, as they attribute the victory in Berlin much more to Rocha Lima's than Oswaldo Cruz's personal merits. In the light of Raízes do Brasil, a classic by Sérgio Buarque de Holanda, this article also addresses the issue regarding the dispute between the Iberian and Anglo-Saxon worlds over the Brazilian victory.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

All children admitted to the PICUs were daily evaluated for the presence of acute respiratory distress syndrome according to the American-European Consensus Conference and Berlin definitions. Of the 562 patients included, acute respiratory distress syndrome developed in 57 patients (10%) and 58 patients (10.3%) according to the Berlin definition and the American-European Consensus Conference definition, respectively. Among patients with acute respiratory distress syndrome according to the Berlin definition, nine patients (16%) were mild, 21 (37%) were moderate, and 27 (47%) were severe. Compared with patients without acute respiratory distress syndrome, patients with acute respiratory distress syndrome had significantly higher severity scores, longer PICU and hospital length of stay, longer duration of mechanical ventilation, and higher mortality (p < 0.001). The presence of two or more comorbidities and admission for medical reasons were associated with development of acute respiratory distress syndrome. Comparisons across the three the Berlin categories showed significant differences in the number of ventilator-free days (21, 20, and 5 d, p = 0.001) and mortality for severe acute respiratory distress syndrome (41%) in comparison with mild (0) and moderate (15%) acute respiratory distress syndrome(p = 0.02). No differences in PICU or hospital stay were

    The waste management of the State of Berlin (Federal Republic of Germany) shall be re-aligned and optimized in particular under the aspects of resource protection and climate change in order to achieve a more relevant reduction of harmful greenhouse gases (carbon dioxide, methane, nitrous oxide) up to the year 2020. In order to evaluate these targets and in order to control the waste streams, an annual material balance, carbon footprint and environmental impact shall be created for non-hazardous wastes. Under this aspect, the authors of the contribution under consideration analyze the waste management situation in the State of Berlin with regard to the waste streams and the associated relevant greenhouse gas emissions. From this, optimization potentials are derived and optimized with respect to their reduction effects. A catalogue of measures for a possible implementation of identified measures is created. A user-friendly Excel tool was developed for the annual implementation of identified measures.

Nas duas décadas passadas, as matrizes hidrofílicas tornaram-se muito populares na formulação de formas farmacêuticas de liberação modificada. A escolha do polímero hidrofílico na formulação da matriz pode fornecer uma combinação apropriada dos mecanismos de intumescimento, de dissolução ou de erosão e determinam a cinética de liberação in vitro. As matrizes de intumescimento são sistemas monolíticos preparados pela compressão de mistura de um polímero hidrofílico e de um fármaco. Elas representam sistemas da liberação em que os vários mecanismos podem ser adaptados ao programa de liberação. O sucesso desses sistemas está relacionado com a tecnologia de fabricação e com as características físicas e físico-químicas do polímero, responsáveis pelo mecanismo de liberação.Drug delivery systems (DDS became an integral part of pharmaceutical research. The majority of oral DDS are matrix-based systems. Hydrophilic matrices for the past two decades have been popular in the formulation of controlled release solid dosage forms. Swellable matrices are monolithic systems prepared by compression of a powdered mixture of a hydrophilic polymer and a drug. They represent a delivery system in which various mechanisms can be adapted to the delivery program. Their success is linked to the established tabletting technology of manufacture. The choice of the hydrophilic polymer in the matrix formulation can provide an appropriate combination of swelling, dissolution or erosion mechanisms to evaluate in vitro release kinetics.

El estudio comprendió, además del examen parasitológico, la determinación del estado nutricional de los niños, utilizando la técnica de Graham modificada y el índice de Kanawati-Mc Laren, respectivamente. Se halló 34,14% de niños parasitados con Enterobius vermicularis y el 18,08% con desnutrición proteico-calórica leve. La correlación de los resultados por medio del análisis de varianza nos permitió concluir, que la infección por Enterobius vermicularis en los preescolares no influye en el rendimiento escolar, aunque no podemos generalizar este resultado, porque no se evaluaron otros enteroparásitos y además el aprestamiento inicial es básicamente motor antes que intelectual. La malnutrición afectaría a los niños de 5 años y no así a los de 3 y 4 años, aunque el método utilizado no fue el mis adecuado.

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

    Full Text Available Can we speak of a Berlin School of Anthropology? During the XXth century the Institut für Ethnologie of the Freien Universität had an intense research activity and a significant plurality of theoretical approaches. Particularly, at the end of the 70’s a wide group of researchers gathered in Berlin around the IfE. These scholars not only focused their attention on specific geographical areas (above all Northeast Africa and Central Asia but also developed common themes which led to the debate on the methodology and epistemology of Anthropology. Research activities catalysed around charismatic figures of German and European Anthropology and this led to the promotion of the idea of long-term fieldwork and to a particular attention to the critical definition of the qualities of ethnological knowledge. With the development and the application of the notion of imaginäre Ethnografie and with the theorization of the modified states of consciousness, the relationship between der Wissenschaftler und das Irrationale – to recall the title of a book published during those years – could finally be reconsidered in a continuous dialogue with researchers such as Hans Peter Duerr and Paul Feyerabend. This is how what I would like to define as “the Berlin stream of Anthropology” was born; and many scholars who later left the IfE for the wide world may or may not recognize themselves in it.

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

    2003-03-01

    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.

    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.

  14. Struggle over energy transition in Berlin: How do grassroots initiatives affect local energy policy-making?

    Blanchet, Thomas

    2015-01-01

    This paper examines the growing role of grassroots initiatives in the governance of urban energy systems. In recent years, research has increasingly underlined the potential for sustainable innovation of community-led bottom-up actions but has at the same time underestimated their potential impact on the governance of energy systems. Based on a strategic action field framework (SAF), this paper analyses the conflicts over the remunicipalisation of Berlin's electricity grid and investigates the creation and strategic development of two grassroots initiatives as well as their interaction with the local government and the established grid operator. We argue that grassroots initiatives have an important impact on the local energy system, not just through their influence on the implementation of local energy policy but above all by their framing of a specific vision of a local energy transition. The paper discusses the scope and limits of such initiatives in an urban context. - Highlights: • Grassroots initiatives as actors with countervailing power in local energy policy. • They increase citizens' awareness and impact the action of the local government. • Grids as objects of struggle between competing visions of energy transition. • Urban context is both a resource and a constraint for grassroots initiatives action

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

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

    The microbial degradation of pharmaceuticals found in surface water used for artificial recharge is strongly dependent on redox conditions of the subsurface. Furthermore the durability of production wells may decrease considerably with the presence of oxygen and ferrous iron due to the precipitation of trivalent iron oxides and subsequent clogging. Field measurements are presented for oxygen at a bank filtration site in Berlin, Germany, along with simplified calculations of different oxygen pathways into the groundwater. For a two-dimensional vertical cross-section, oxygen input has been calculated for six scenarios related to different water management strategies. Calculations were carried out in order to assess the amount of oxygen input due to (1) the infiltration of oxic lake water, (2) air entrapment as a result of water table oscillations, (3) diffusive oxygen flux from soil air and (4) infiltrating rainwater. The results show that air entrapment and infiltrating lake water during winter constitute by far the most important mechanism of oxygen input. Oxygen input by percolating rainwater and by diffusive delivery of oxygen in the gas phase is negligible. The results exemplify the importance of well management as a determining factor for water oscillations and redox conditions during artificial recharge.

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

    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.

    Aquifer Thermal Energy Storage (ATES) is a sustainable alternative for storage and seasonal availability of thermal energy. However, its impact on the subsurface flow regime is not well known. In Berlin (Germany), the Jurassic (Hettangian) sandstone aquifer with highly mineralized groundwater (TDS 27 g/L) is currently used for heat storage. The aim of this study was to examine the hydrogeochemical changes that are caused by the induced temperature shift and its effects on the hydraulic permeability of the aquifer. Column experiments were conducted, in which stainless steel columns were filled with sediment from the aquifer and flushed with native groundwater for several weeks. The initial temperature of the experiment was 20°C, comparable to the in-situ conditions within the aquifer. After reaching equilibrium between sediment and water, the temperature was increased to simulate heating of the aquifer. During the experiment, physical and chemical parameters (pH, ORP, dissolved oxygen and dissolved carbon dioxide) were measured at the outflow of the column and the effluent water was sampled. Using a Scanning Electron Microscope, the deposition of precipitated minerals and biofilm on sediment grains was analyzed. Changes in hydraulic properties of the sediment were studied by the use of tracer tests with Uranin.

    The present study aims to explore the relationship between rainfall variables and water quality/quantity characteristics of combined sewer overflows (CSOs), by the use of multivariate statistical methods and online measurements at a principal CSO outlet in Berlin (Germany). Canonical correlation results showed that the maximum and average rainfall intensities are the most influential variables to describe CSO water quantity and pollutant loads whereas the duration of the rainfall event and the rain depth seem to be the most influential variables to describe CSO pollutant concentrations. The analysis of partial least squares (PLS) regression models confirms the findings of the canonical correlation and highlights three main influences of rainfall on CSO characteristics: (i) CSO water quantity characteristics are mainly influenced by the maximal rainfall intensities, (ii) CSO pollutant concentrations were found to be mostly associated with duration of the rainfall and (iii) pollutant loads seemed to be principally influenced by dry weather duration before the rainfall event. The prediction quality of PLS models is rather low (R² < 0.6) but results can be useful to explore qualitatively the influence of rainfall on CSO characteristics.

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

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

    Following a request by the Australian government, human remains of Australian origin were identified in the anatomical collection of Charité, the medical faculty of Berlin. We initiated an interdisciplinary provenance research on such remains to ensure their identity, elucidate their history, and prepare for a possible return to Australia. Here, we present results regarding a skull in the collection labeled as stemming from Tasmania. The non-invasive anthropological investigation revealed the skull to stem from a girl of about 15 years of age who most likely died of a massive otitis/petrositis with subsequent meningitis. These results match the historical findings, which started from an inscription on the frontal bone giving a first name ("Nanny"), an ancestry ("native of Kangaroo Island"), a collector ("Schayer"), and a location ("van Diemensland", i.e. Tasmania). The collector, Adolph Schayer, was a German sheep breeder and botanical/zoological collector living in north-western Tasmania from 1831 to 1843. In archival sources, a girl named Nanny Allan could be identified, who was a native of Kangaroo Island and died in Launceston/Tasmania in 1836 at the age of about 14 years. As there were no doubts that these remains stem from a Tasmanian individual, they were handed over to representatives of the Tasmanian Aboriginal Centre in July 2014.

    Gerhardt, Uta

    2014-01-01

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

    In the Federal Republic of Germany the rate of the childless women rises. While the topic of unwanted childlessness among gynecologists receives broad attention among gynecologists, the question of (temporaryly?) intended renouncement of pregnancy and birth is of little interest. For the former GDR a low age with the firstborn and a high mother rate were typically. After the "turn" serious modifications of the birth rate in East Germany happened. The available study examined 1996 motives for and against a child with 554 up-to-date wanted childless women in East- and West-Berlin (population-referred sample). In the questionnaire, besides sociodemographic data, information was raised to own childhood, partnership, occupation, satisfaction with life and for child desire motivation. Apart from the school and vocational termination conceptions on the age with the firstborn, disadvantages for a life with child and value hierarchies for partnership and family were important for the description of the dilemma of compatibility of occupation and family. Eastsocialized women consider a compatibility rather possible. Targets for vocational development and responsible parenthood for young women come into conflict. Temporal delaying of the child desire leads to an increase of intended and unwanted childlessness with various (psychosomatic) effects on obstetrics and gynecology.

    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.

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

    To compare the health status and factors influencing the health of populations that had previously lived under different political systems. Cross sectional health and social survey using postal interviews. The relation between self reported health and psychosocial factors (stressful life events, social support, education, health promoting life style and health endangering behaviour) was investigated. To determine East-West differences a logistic regression model including interaction terms was fitted. East and West Berlin shortly after reunification 1991. Representative sample of 4430 Berlin residents aged 18 years and over (response rate 63%). Of all respondents, 15.4% rated their health as unsatisfactory. Residents of East Berlin rated their health more frequently as unsatisfactory than residents of West Berlin (Or(age adjusted)= 1.29, 95%CI 1.08, 1.52), these differences occurred predominantly in the over 60 years age group. Logistic regression showed significant independent effects of stressful life events, social support, education, and health promoting life style on self rated health. The effects of education and health promoting life style were observed to be more pronounced in the western part of Berlin. Old age and female sex showed a stronger association with unsatisfactory health status in the eastern part of Berlin. For subjects aged over 60 years there was evidence that living in the former East Berlin had an adverse effect on health compared with West Berlin. The impact of education and a health promoting lifestyle on self rated health seemed to be weaker in a former socialist society compared with that of a Western democracy. This study supports an "additive model" rather than a "buffering model" in explaining the effects of psychosocial factors on health.

    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.

    The reunification of Germany confronted citizens in East and West Germany with many changes in their lives. These changes may be considered as critical life events. Especially for those in East Germany, life circumstances drastically changed, and individuals were increasingly required to adopt and develop coping capabilities. In addition to new opportunities and freedom, there was threatening uncertainty about the future. Theories of life events and stress postulate that threat events have an impact on human well-being. It was expected that there would be an increased rate of psychiatric morbidity after unification, especially in the eastern part of Germany. An international study by the WHO on psychiatric disorders in general health care was carried out in 1990, 1 year after the opening of the Berlin Wall, in both parts of Berlin and in Mainz, West Germany. This allowed for a comparison of the prevalence rates of psychiatric disorders among general health care patients in the East and West, after the euphoria immediately following unification had subsided. The prevalence rates of current ICD-10 diagnoses and of subthreshold disorders in East Berlin were similar to the rates in West Berlin and Mainz. The recognition rate of psychiatric disorders by physicians did not differ in East Berlin as compared to West Berlin and Mainz. Contrary to the prediction expected from the literature on individual negative life events, major changes in life circumstances and stressful life events on a societal level within 1 year did not have a major impact on psychological function.

    Full Text Available This work describes three C8-stationary phases for high performance liquid chromatography based on silica metallized with ZrO2, TiO2 or Al2O3 layers, having poly(methyloctylsiloxane immobilized onto their surfaces. The stationary phases were characterized using XRF, XAS, FTIR, SEM and elemental analysis to determine the physical characteristics of the oxide and polysiloxane layers formed on the surfaces and chromatographically to evaluate the separation parameters. The results show the changes on the silica surface and allowed proposing a structure for the oxide layer, being observed tetrahedral and octahedral structures, what is completely new in the literature. The formation of a homogeneous layer of metallic oxide (TiO2 and ZrO2 was observed on the silica. The C8-titanized and C8-aluminized stationary phases presented good chromatographic performances, with good values of asymmetry and efficiency. All stationary phase presented few loss of the polymeric layer after the HPLC, indicating that this layer is well attached on the metalized support.

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

    One quality parameter of medical theses is the number of articles published by the doctoral candidates. Over the course of the past decade the Charité-Universitätsmedizin Berlin has taken steps to improve the quality of the theses completed by its doctoral students in medicine and increase their publication activity. This study was designed to verify the efficacy of these measures and to detect general trends. Medical theses completed in 1998, 2004 and 2008 (sample size >250 for each year) were retrospectively analyzed with regard to associated publications within a 7-year period (from 5 years before completion to 2 years thereafter). Quality and quantity were recorded. Publications found in the PubMed database were evaluated; the impact factor of the publishing journal was used as quality parameter. The sample sizes were 264 for 1998, 316 for 2004, and 316 for 2008. The number of publications per doctoral student increased from 0.78 to 1.39 over the course of the study period, and the average impact factor rose from 2.42 to 3.62. Analysis using the current impact factors of the publishing journals showed an increase from 3.13 to 3.85. The proportion of case reports fell from 12.7% to 8%. The proportion of first authorships remained about the same. The past decade has seen an increase in the number of publications by doctoral students at the Charité and a rise in the average impact factor of the journals concerned.

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

    Full Text Available BACKGROUND: Obstructive sleep apnea syndrome (OSAS is a highly prevalent sleep-related disorder that is associated with increased risk of hypertension (HTN and coronary heart disease. This study aimed to evaluate the correlation between the OSAS and coronary artery disease (CAD severity. METHODS: The cross-sectional study was conducted from September 2012 to December 2013. We enrolled 127 patients with chronic stable angina who were referred for coronary angiographic studies in Shahid Chamran and Nour Hospitals in Isfahan, Iran. The Berlin questionnaire (BQ was used for estimate the probability of OSAS in patients as a low or high probability. Demographic characteristics and metabolic risk factors including diabetes mellitus, HTN, obesity, and smoking also were recorded. The severity of CAD was assessed and compared based on the Gensini score with Mann–Whitney U statistical test. Independent t-test for continuous variables and chi-square test for categorical variables were used. RESULTS: Totally, 65.4% of subjects were considered as high and 34.6% as low probability for OSAS, which 81.1% of them had CAD. There was a significant difference between body mass index, systolic blood pressure, diastolic blood pressure, and ischemic heart disease drug consumption with OSAS probability (P < 0.0500. CAD was accompanied by OSAS significantly (P = 0.0260. The Gensini score was significantly higher in patients with high OSAS probability (100.4 ± 69.1 vs. 65.3 ± 68.9; P = 0.0030. OSAS also increase odds of CAD based on regression analysis (odds ratio, 95% confidence interval = 2.7. CONCLUSION: This study indicates that more severe CAD is associated with high OSAS probability identified by BQ.

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

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

    Some patients presenting with acute respiratory failure and meeting the Berlin criteria for acute respiratory distress syndrome (ARDS) lack exposure to common risk factors (CRF). These so-called ARDS mimickers often lack histological diffuse alveolar damage. We aimed to describe such ARDS mimickers lacking CRF (ARDS CRF-) in comparison with others (ARDS CRF+). Retrospective study including all patients receiving invasive mechanical ventilation for ARDS admitted to the intensive care units (ICUs) of two tertiary care centers from January 2003 to December 2012. The prevalence of ARDS CRF- was 7.5 % (95 % CI [5.5-9.5]; n = 50/665). On the basis of medical history, bronchoalveolar lavage fluid cytology, and chest CT scan patterns, four etiological categories were identified: immune (n = 18; 36 %), drug-induced (n = 13; 26 %), malignant (n = 7; 14 %), and idiopathic (n = 12; 24 %). Although the ARDS CRF- patients had a lower logistic organ dysfunction score (4 [3-8] vs. 10 [6-13]; p logistic regression analysis (adjusted OR = 2.06; 95 % CI [1.02-4.18]; p = 0.044). Among ARDS CRF- patients, the presence of potentially reversible lung lesions with corticosteroids (aOR = 0.14; 95 % CI [0.03-0.62]) was associated with ICU survival. The absence of CRF among patients with ARDS is common and associated with a higher risk of mortality. For such atypical ARDS, a complete diagnostic workup, including bronchoalveolar lavage fluid cytology and chest CT scan patterns, should be performed to identify those patients who might benefit from specific therapies, including corticosteroids.

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

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

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

    Our objective was to compare the prevalence and outcomes of pediatric acute respiratory distress syndrome using the Pediatric Acute Lung Injury Consensus Conference (PALICC) criteria and Berlin definitions. We screened case records of all children aged 1 month to 17 years of age admitted to the Pediatric Intensive Care Unit (PICU) over a 3-year period (2015-2017) for presence of any respiratory difficulty at admission or during PICU stay. We applied both PALICC and Berlin criteria to these patients. Data collection included definition and outcome related variables. Data were compared between the "PALICC only group" and the "Berlin with or without PALICC" group using Stata 11. Of a total of 615 admissions, 246 were identified as having respiratory difficulty at admission or during PICU stay. A total of 61 children (prevalence 9.9%; 95% CI: 7.8-12.4) fulfilled the definition of acute respiratory distress syndrome (ARDS) with either of the two criteria. While 60 children (98%) fulfilled PALICC criteria, only 26 children (43%) fulfilled Berlin definition. There was moderate agreement between the two definitions (Kappa: 0.51; 95% CI: 0.40-0.62; observed agreement 85%). Greater proportion of patients had severe ARDS in the "Berlin with or without PALICC group" as compared to the "PALICC only" group (50 vs. 19%). There was no difference between the groups with regard to key clinical outcomes such as duration of ventilation (7 vs. 8 days) or mortality [51.4 vs. 57.7%: RR (95% CI): 0.99 (0.64-1.5)]. In comparison to Berlin definition, the PALICC criteria identified more number of patients with ARDS. Proportion with severe ARDS and complications was greater in the "Berlin with or without PALICC" group as compared to the "PALICC only" group. There were no differences in clinical outcomes between the groups.

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

    Full Text Available Resumen: La interacción entre variables es una característica inherente de los procesos multivariables, que dificulta su operación y el diseño de sus sistemas de control. Bajo el paradigma de Control por desacoplo se agrupan un conjunto de metodologías, que tradicionalmente han estado orientadas a eliminar o reducir la interacción, y que recientemente algunos investigadores han reorientado con objetivos de solucionar un problema tan complejo como es el control multivariable. Parte del material descrito en este artículo es bien conocido en el campo del control de procesos, pero la mayor parte de él son resultados de varios años de investigación de los autores en los que han primado la generalización del problema, la búsqueda de soluciones de fácil implementación y la combinación de bloques elementales de control PID. Esta conjunción de intereses provoca que no siempre se pueda conseguir un desacoplo perfecto, pero que sí se pueda conseguir una considerable reducción de la interacción en el nivel básico de la pirámide de control, en beneficio de otros sistemas de control que ocupan niveles jerárquicos superiores. El artículo resume todos los aspectos básicos del Control por desacoplo y su aplicación a dos procesos representativos: una planta experimental de cuatro tanques acoplados y un modelo 4×4 de un sistema experimental de calefacción, ventilación y aire acondicionado. Abstract: The interaction between variables is inherent in multivariable processes and this fact may complicate their operation and control system design. Under the paradigm of decoupling control, several methodologies that traditionally have been addressed to cancel or reduce the interactions are gathered. Recently, this approach has been reoriented by several researchers with the aim to solve such a complex problem as the multivariable control. Parts of the material in this work are well known in the process control field; however, most of them are

    Many European cities continue to struggle with meeting the European air quality limits for NO2. In Berlin, Germany, most of the exceedances in NO2 recorded at monitoring sites near busy roads can be largely attributed to emissions from traffic. In order to assess the impact of changes in traffic emissions on air quality at policy relevant scales, we combine the regional atmosphere-chemistry transport model WRF-Chem at a resolution of 1kmx1km with a statistical downscaling approach. Here, we build on the recently published study evaluating the performance of a WRF-Chem setup in representing observed urban background NO2 concentrations from Kuik et al. (2016) and extend this setup by developing and testing an approach to statistically downscale simulated urban background NO2 concentrations to street level. The approach uses a multilinear regression model to relate roadside NO2 concentrations observed with the municipal monitoring network with observed NO2 concentrations at urban background sites and observed traffic counts. For this, the urban background NO2 concentrations are decomposed into a long term, a synoptic and a diurnal component using the Kolmogorov-Zurbenko filtering method. We estimate the coefficients of the regression model for five different roadside stations in Berlin representing different street types. In a next step we combine the coefficients with simulated urban background concentrations and observed traffic counts, in order to estimate roadside NO2 concentrations based on the results obtained with WRF-Chem at the five selected stations. In a third step, we extrapolate the NO2 concentrations to all major roads in Berlin. The latter is based on available data for Berlin of daily mean traffic counts, diurnal and weekly cycles of traffic as well as simulated urban background NO2 concentrations. We evaluate the NO2 concentrations estimated with this method at street level for Berlin with additional observational data from stationary measurements and

  18. How many years of life did the fall of the Berlin Wall add? A projection of East German life expectancy.

    Vogt, Tobias C

    2013-01-01

    In the two decades since reunification, East Germans have experienced a large increase in life expectancy and a convergence with the West German mortality level. This gain in life expectancy appears even more impressive if we assume a different scenario in which the Berlin Wall did not fall, and the old East Germany still existed. This analysis takes into account that East German mortality would not have remained static without reunification. Thus, it shows how many years of life expectancy were actually added by the fall of the Berlin Wall. The analysis shows the improvements for single age groups by projecting life expectancy based on mortality levels during the 1970s and 1980s using the Lee-Carter method. I use national-level data for both sexes for East Germany before reunification. I find that, without reunification, current life expectancy at birth among East Germans would be 4.0 years lower for females and 5.7 years lower for males. I also show that older East Germans were the main demographic beneficiaries of reunification. Female and male mortality improvements in the age groups above 60 contributed up to 80% to the actual gains in life expectancy. Had the Berlin Wall not fallen, East German mortality would not have remained static but improved at a far slower rate. Thus, this counterfactual approach shows for the first time how many years of life were actually gained by reunification and how much of these gains were attributable to mortality improvements among the elderly.

  19. 75 years ago. The discovery of nuclear fission during the neutron irradiation of uranium on 17 December 1938 in Berlin

    International Nuclear Information System (INIS)

    Kuczera, Bernhard

    2013-01-01

    A ground-breaking, scientific discovery made in the Berlin experiments of the year 1938 on neutron irradiation of uranium, was that atom nuclei can be fissured and, during the fission energy, so-called nuclear energy, is released. If further U-235 atoms are in the immediate vicinity, the released neutrons can trigger a chain reaction of the nuclear fission. The story of this ground-breaking discovery that led to the worldwide civil utilisation of nuclear energy is outlined here. The discovery of neutrons and their implementation in radiation experiments occurred in the 1930s. The research work followed the model of the Stockholm citizen Niels Bohr on the configuration of an atom. In 1930, Walther Bothe reported on the occurrence of a high-energy radiation when beryllium was irradiated with alpha-particles. James Chadwick could prove experimentally in 1932 that this is a current of high-energy, electrically neutral particles. He called these particles neutrons. In Berlin, the radio-chemist Otto Hahn is the Director at the Kaiser-Wilhelm-Institute for Chemistry and head of the chemical-radioactive department. In the years 1935 to 1938, the radiation experiments of uranium with neutrons were at the centre of the research in Berlin. In October 1938, Hahn and Strassmann responded with their own experiments to the scientific challenge of Irene Curie and Paul Savitch of 3.5-hours of activity when uranium was radiated with neutrons. The decisive discovery for the neutron radiation of uranium was made by Hahn and Strassmann on 17 December 1938. From the results of different experiments, they conclude: 'Our radium isotopes have the properties of barium.' On 19 December, Hahn informs Lise Meitner and speaking on the issue of 'Where does the barium come from?' addresses a possible 'bursting' of the uranium nucleus. That is Hahn's 'Heureka.' moment: He recognises that the neutron radiation does not only effect radiochemical transformations, but can also cause the uranium

    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.

    The international image of Sweden is one of a small, democratic and peace-loving country without the moral burden of a colonial past. This image has been reproduced in Swedish government policy as well as in most historical accounts. However, in this Current African Issues publication, the notion that “Sweden lacks a colonial past in Africa” is brought into question. The Berlin Conference 1884-85 is perhaps the most infamous political event in the history of European domination of Africa. At ...

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

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

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

Existem poucos trabalhos sobre o volume mínimo efetivo de anestésico local para o bloqueio do plexo braquial via axilar (BPVA. Este estudo foi conduzido com o objetivo de determinar o volume mínimo efetivo (VE90 de bupivacaína 0,5% comadrenalina (1:200.000 para o BPVA guiado por ultrassom. Método: o método up-and-down proposto por Massey e Dixon foi usado para o cálculo do volume mínimo efetivo. A dose inicial foi de 5 ml por nervo (radial, mediano, ulnar e musculocutâneo. No caso de falha do bloqueio, o volume era aumentado em 0,5 mL por nervo. O sucesso do bloqueio resultava na diminuição do volume em 0,5 mL por nervo para o paciente subsequente. O sucesso do bloqueio foi definido como bloqueio da função motora ≤ 2 segundo a escala de Bromage modificada, ausência de sensibilidade térmica e de resposta ao pinprick. Foi definido como critério para término do estudo a obtenção de cinco casos de falha seguidos de casos de sucesso. Resultados: foram incluídos 19 pacientes no estudo. O volume mínimo efetivo (VE90 de bupi-vacaína 0,5% com 1:200.000 de adrenalina foi de 1,56 ml (IC 95% 0,99-3,5 por nervo. Conclusão: este trabalho corrobora alguns estudos que mostram que é possível obter anestesia cirúrgica com baixos volumes de anestésico local para bloqueios de nervo periférico guiados por ultrassom.

    SUMARIO Y CONCLUSIONES

    1. La sordera ocupacional debe ser motivo de preocupación en medicina industrial, por cuanto constituye grave problema para los obreros que trabajan en ambiente de intensidades superiores a 90 decibeles. Consideramos de capital importancia iniciar urgente campaña para el estudio preventivo y profilaxis del ruido.

    2. Los efectos que produce el ruído sobre la audición están ampliamente demostrados y, de acuerdo con la experiencia, su incidencia es cada día más frecuente en nuestro medio,
    donde un alto porcentaje del personal obrero trabaja en ambientes sin ninguna protección y con grave peligro para su función auditiva.

    3. La sordera ocupacional presenta características muy definidas, pero sólo un estudio otológico completo y la colaboración entre el otólogo, el ingeniero técnico en acústica y el
    médico industrial permiten definir la conducta por seguir, su profilaxis y su tratamiento.

    4. Las alteraciones orgánicas producidas en el oído por el trauma acústico son permanentes e irreversibles. Las estructuras del órgano de Corti una vez lesionadas no pueden ser
    reemplazadas.

    5. Sugerimos la creación del Comité Nacional de Conservación de la Audición con un programa que incluya:
    a Formación de personal especializado.
    b Estudio, reducción y control del ruído en la industria.
    c Creación de la ficha audiológica obligatoria de ingreso para el personal obrero.
    d Control periódico, protección del personal y adaptación de protectores acústicos.
    el Establecimiento de normas mínimas acústicas en la construcción de las fábricas.

    6. Las tablas de indemnización laboral por sordera deben ser modificadas, adoptando un sistema práctico, conforme con la legislación establecidaen otros países.

    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.

As a Europe of 25 is now a reality, the Forum will obviously focus on this situation and the prospects for LP Gas in the new group without, however, neglecting the global issues which are why it exists. The WLPGA has a new Managing Director, James Rockall, since 2 August. He previously held the post of Director of Market Development for the Association from july 2003. The 2004 action plan of the World LP Gas Association forms part of the strategic decisions taken at the end of 2001 for the period 2002-2006. Its structure remains identical to that of the previous plan but with the continuous rise in 'the good industrial practices', there is one programme more than in 2003. There is particular emphasis on the programme for developing LP Gas markets in rural areas, at the core of which is the LP Gas Rural Energy Challenge launched 2 years ago in the framework of a partnership with the UNPD. Moreover, the WLPGA contribution to the preparation of the World Energy Outlook of the LEA is testimony to the reinforcement of relations with this agency, and the Association also took part in the World Energy Congress in Sydney. The other programmes are also progressing: GAIN, GLOTEC, without forgetting the preparation of the annual forum and the services provided directly to WLPGA members. Having decided on a change of direction in his career, Emmanuel Chantelot left the WLPGA and the LP Gas industry on 31 July 2004. He should be attending the Members' Dinner at the Berlin Forum. Emmanuel Chantelot has led the World Association for just over 7 years as Managing Director. (authors)

Además de las conferencias impartidas se visitaron las obras que habían sido analizadas en el seminario. Este artículo, escrito en marzo de 2001, añade una reflexión final, escrita en marzo del año 2002, consecuencia de esa visita conjunta que, profesores y estudiantes, realizaron al Reigchstag. Con el cambio de milenio, las principales ciudades europeas tratan de actualizarse utilizando la arquitectura de vanguardia y recurriendo a las principales firmas del momento. La forma de reconstruir Berlín entra en debate tras la experiencia de la IBA de los años ochenta. La reconstrucción del Reichstag supone además recuperar parte de la historia reciente de esta ciudad. Convertido en el símbolo de Berlín desde la era Guillermina, se mantuvo en la caída de la República de Weimar, durante el régimen de Hitler y con la división y finalmente reunificación de Alemania. El proyecto de Paul Wallot, la intervención de Paul Baumgarten y la propuesta de Norman Foster dan testimonio de esta historia a la que no son ajenas las diferentes decisiones que los arquitectos tuvieron que tomar en cada momento. El concurso, compuesto por dos fases, planteaba sobre todo el problema de la reconstrucción de la cúpula demolida por Baumgarten. Foster realizó dos proyectos distintos, uno en cada fase, con cambios sustanciales, en el basamento y en la forma de la cubrición del espacio central de la Sala de la Asamblea. Impuesta la reconstrucción de la cúpula, con la solución definitiva propuesta por Foster, se recupera el sentido público de este edifico en la ciudad y se muestra una vez más el camino emprendido por este arquitecto para lograr nuevos ingenios modulares y prefabricados en arquitectura.

    Full Text Available Die Öffentlichkeitsarbeit der Staatsbibliothek zu Berlin zielt auf eine wirksame Darstellung ihrer bibliothekarischen Weltschätze und ihrer Serviceangebote für die Wissenschaft ab. Sie ruht auf drei Säulen: kulturelle Breitenbildung für wenig bibliotheksaffine Kreise, allgemeine und breit gefächerte Öffentlichkeitsarbeit sowie Aktionen, die sich an spezielle communities in der Wissenschaft richten. Der Beitrag informiert auch über die erfolgreiche Umsetzung dieser Strategie anhand zahlreicher Beispiele. Er zeigt, wie es der Staatsbibliothek in der Hauptstadt Berlin, in der viele Gedächtnisinstitutionen tätig sind, gelingt, öffentlich präsent zu bleiben und ihr Profil zu vermitteln. The public relations work of the Berlin State Library – Prussian Cultural Heritage aims at effectively presenting its globally significant treasures as well as its services for the scientific world. It is based on three pillars: cultural education for the general public, especially for people who are not naturally close to libraries; a general and wide variety of public relations work; and events which target special communities in science. The paper also presents many examples for the effectual implementation of this strategy. It shows how the State Library, in the capital city of Berlin with its many memory institutions, succeeds in keeping a strong presence and communicating its profile to the public.

    2016-05-01

    Full Text Available The regional non-hydrostatic climate model COSMO-CLM is increasingly being used on fine spatial scales of 1–5 km. Such applications require a detailed differentiation between the parameterization for natural and urban land uses. Since 2010, three parameterizations for urban land use have been incorporated into COSMO-CLM. These parameterizations vary in their complexity, required city parameters and their computational cost. We perform model simulations with the COSMO-CLM coupled to these three parameterizations for urban land in the same model domain of Berlin on a 1-km grid and compare results with available temperature observations. While all models capture the urban heat island, they differ in spatial detail, magnitude and the diurnal variation.

    Simon, Ute; Brüggemann, Rainer; Pudenz, Stefan

    2004-04-01

    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.

  15. Extraction of highly charged ions from the Berlin Electron Beam Ion Trap for interactions with a gas target

    Allen, F.I.; Biedermann, C.; Radtke, R.; Fussmann, G.

    2006-01-01

    Highly charged ions are extracted from the Berlin Electron Beam Ion Trap for investigations of charge exchange with a gas target. The classical over-the-barrier model for slow highly charged ions describes this process, whereby one or more electrons are captured from the target into Rydberg states of the ion. The excited state relaxes via a radiative cascade of the electron to ground energy. The cascade spectra are characteristic of the capture state. We investigate x-ray photons emitted as a result of interactions between Ar 17+ ions at energies ≤5q keV with Ar atoms. Of particular interest is the velocity dependence of the angular momentum capture state l c

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

    2012-07-01

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

    1997-09-01

    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.

    In collaboration with the research reactor of the Helmholtz-Zentrum Berlin fuer Materialien und Energie, the Gemaeldegalerie Berlin is the only institute worldwide, which systematically employs the method of Neutron-Activation-Autoradiography to analyze paintings and painting techniques. To date more than 70 paintings were investigated with this effective, non-destructive, and exceptional method. It allows the visualization of structures and layers beneath the top surface and, in addition, enables the identification of elements contained in the pigments. The instrument B8 at the research reactor BER II is dedicated to this research. Jan Steen is one of the prolific artists from the 17th century. Like other artists from that time he produced several versions of one specific topic during life-time. The topic 'As the old ones sing, so the young ones pipe' was painted by Jan Steen in 13 versions. The painting from the Gemaeldegalerie is an exception in this series as it differs in style and content from the other oeuvres. The question arises: why did the artist deviate from his usual scheme? The possible answer is provided by X-ray images and neutron autoradiographs made of the painting, allowing insight into hidden paint layers and, therefore, in the genesis of the painting. Jan Steen did not simply change the composition of the room and the figures. He originally intended an altogether different topic. Assumedly it was supposed to be a so-called merry company, located in a generous, stately room. Many pieces of this sophisticated ambiance have been eliminated from the version visible today; others were modified and integrated into the composition of the new painting. Thus, Jan Steen commenced the topic 'As the old ones sing, so the young ones pipe' from a different context.

    Full Text Available This paper is intended to introduce Nana Rademacher, one of the contemporary female science fiction writers in Germany, and to study her work Wir Waren Hier (We Were Here, 2016 which has been seen as an anti-utopian fiction by different critics. In this study, the focus is on anti-utopia which has become a popular literary genre as a result of social, economic and political disappointment experienced in the 20th and 21st centuries. The protagonist, fifteen-year-old Anna, lives in a devastated Berlin which lies in ruins following several years of inter-state conflict which has now been under the hegemony of civil war and military rule. Self-preservation and lawlessness has become the order of the day. Anna’s perspective on her broken world is passionate, strange, harsh and desperate, but also full of hope. This is the story of a girl searching for a way forward in spite of all the obstacles, and who is fighting for life, love and freedom. The struggle for existence/survival in an authoritarian-totalitarian system, as an important characteristic of an anti-utopian society, is one of the basic topics which is fictionalized by Rademacher and narrated by Anna within the work. Extremities, hopelessness, violence, war and the end of the mankind as a result of technology take place in this work. This study aims to determine whether and to what extent the work of Rademacher occurs as an anti-utopian book and how it makes Berlin a part of anti-utopian world.

    Maternal excessive weight and smoking are associated with an increased risk of pregnancy complications and adverse pregnancy outcomes. In Germany, immigrant women have a higher prevalence of pre-pregnancy overweight/obesity compared with autochthonous women. We compared the contribution of pre-pregnancy overweight/obesity to adverse pregnancy outcomes among immigrant and autochthonous women in Berlin/Germany. Data from 2586 immigrant women (from Turkey, Lebanon, other countries of origin) and 2676 autochthonous women delivering in three maternity hospitals of Berlin within 12 months (2011/2012) was used. Cox regression models were applied to estimate the association between overweight/obesity and smoking with the outcomes large-for-gestational-age (LGA), small-for-gestational-age (SGA), preterm birth (PTB) and extreme preterm-birth (E-PTB). Population attributive fractions (PAF) were calculated to quantify the proportion of the outcomes attributable to overweight/obesity and smoking, respectively. Prevalence of overweight and obesity was 33.4% among autochthonous and 53.6% among Turkish women. Prevalence risk ratios of excessive weight were highest for LGA infants among immigrant and autochthonous women. The PAFs were -11.8% (SGA), +16.3% (LGA), +3.6% (PTB) and +16.5% (E-PTB) for the total study population. Overweight/obesity is strongly associated with an increased risk of delivering an LGA infant among both immigrant and autochthonous women. Compared with autochthonous women, the contribution of excessive weight to LGA is even higher among immigrant women, in whom PAFs of overweight/obesity even exceed those of smoking for some outcomes. © The Author 2015.

  3. The impact of traffic emissions on air quality in the Berlin-Brandenburg region - a case study on cycling scenarios

    2016-12-01

    Many European cities continue to struggle with exceedances of NO2 limit values at measurement sites near roads, of which a large contribution is attributed to emissions from traffic. In this study, we explore how urban air quality can be improved with different traffic measures using the example of the Berlin-Brandenburg region. In order to simulate urban background air quality we use the Weather Research and Forecasting model with chemistry (WRF-Chem) at a horizontal resolution of 1km. We use emission input data at a horizontal resolution of 1km obtained by downscaling TNO-MACC III emissions based on local proxy data including population and traffic densities. In addition we use a statistical approach combining the simulated urban background concentrations with information on traffic densities to estimate NO2 at street level. This helps assessing whether the emission scenarios studied here can lead to significant reductions in NO2 concentrations at street level. The emission scenarios in this study represent a range of scenarios in which car traffic is replaced with bicycle traffic. Part of this study was an initial discussion phase with stakeholders, including policy makers and NGOs. The discussions have shown that the different stakeholders are interested in a scientific assessment of the impact of replacing car traffic with bicycle traffic in the Berlin-Brandenburg urban area. Local policy makers responsible for city planning and implementing traffic measures can make best use of scientific modeling results if input data and scenarios are as realistic as possible. For these reasons, the scenarios cover very idealized optimistic ("all passenger cars are replaced by bicycles") and pessimistic ("all cyclists are replaced by cars") scenarios to explore the sensitivity of simulated urban background air quality to these changes, as well as additional scenarios based on city-specific data to analyze more realistic situations. Of particular interest is how these impact

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

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

The effect of the particle size and Na+ exchange on the flow curves of 6% wt/wt suspensions of smectites with and without Na2CO3 were examined. Mineralogical, structural and physicochemical characteristics were studied by X-ray diffraction (XRD, infrared spectroscopy (IR, cationic exchange capacity (CEC, Mg2+, Al3+ determinations, particle size distribution and swelling index (SI. Grinding in an oscillating mill modified the particle sizes. The montmorillonite grain size and the structural disorder increased after larger grinding times. The grinding treatment modified the apparent viscosity and the yield stress of the montmorillonite suspensions. The homoionic Na Cheto-type montmorillonite with fine particle size (obtained by grinding increased the flow properties. Nevertheless, rheological properties were lower than those of suspensions of the Wyoming-type montmorillonite. Montmorillonite-types reacted differently with Na2CO3 additions and this behavior may be related to their structural composition. The Na2CO3 activation improved the flow properties of the original Wyoming-type montmorillonite and after 30 s grinding.Foram encontradas mudanças reológicas em suspensões de esmectitas (montmorillonitas tipos Wyoming e Cheto após modificações estruturais.

Se encontró una tasa global de prevalencia del 4.9%, de los cuales el 3.1% fueron del subtipo inatento, el 1.1% hiperactivo, y el 0.7% combinado. Solo se encontraron diferencias significativas en función del sexo, donde la incidencia fue superior en varones. Las implicaciones educativas y socio sanitarias de los hallazgos encontrados nos sugieren la importancia de llevar a cabo una identificación, diagnóstico y tratamiento temprano, lo que ayudará a que los niños identificados con TDAH puedan desarrollar todo su potencial, y con ello una reducción importante del gasto público.

    Full Text Available O presente trabalho aborda o tratamento superficial de fibras de carbono por ácidos clorídrico e nítrico, visando o aumento controlado da rugosidade superficial da fibra e assim melhorar a ligação fibra/matriz no processamento de compósitos poliméricos reforçados com fibras longas. Foram utilizadas fibras de carbono com size, da empresa Toray. Essas foram tratadas com os ácidos clorídrico e nítrico, a 103°C, em concentrações de 35,5 % e 97 %, em massa, respectivamente, em tempos de exposição de 5, 10, 20, 30, 40 e 60 minutos. As fibras modificadas quimicamente foram caracterizadas por microscopia eletrônica de varredura e por ensaios mecânicos de tração e os dados foram tratados pelo método estatístico de Weibull. Os resultados mostram que os tratamentos empregados modificam a superfície da fibra e que períodos de tratamento superiores a 20 minutos as danificam, degradando de maneira significativa as suas propriedades mecânicas.

    Full Text Available La interferencia electromagnética producida por los sistemas de comunicación de banda ancha por línea de potencia (en inglés, Broadband over Power Lines [BPL] en redes residenciales es un aspecto técnico que no está totalmente solucionado. Este artículo presenta una técnica en la cual la longitud y la carga de los ramales de la red, cuya topología es de bus, son modificadas para variar la función de transferencia del canal entre un transmisor y un receptor, con el objeto de disminuir la densidad espectral de potencia (DEP del transmisor. El algoritmo que desarrolla esta técnica hace uso de tres principios teóricos encontrados: la ganancia por distancia, la construcción discreta de la capacidad de canal y direccionalidad de los nodos de transmisión y recepción. Se estudió una red típica y, como resultado, combinando esta técnica con la técnica conocida como Adaptive Transmit Power Management (ATPM se logró una reducción de 26.4 dB en la densidad espectral de potencia.

    Full Text Available Os frutos da pinheira possuem limitações para sua distribuição a mercados distantes, por causa do rápido amadurecimento, que os torna muito macios, de difícil manuseio sem a ocorrência de danos e de conservação extremamente reduzida. O objetivo deste trabalho foi avaliar a influência do filme de policloreto de vinila (PVC, associado às temperaturas de refrigeração, na conservação pós-colheita da pinha. Os frutos foram selecionados, lavados, sanitizados e acondicionados em bandejas de isopor, com, ou sem, envolvimento de película de policloreto de vinila, e conservados a 12 e 25 ºC. Foram avaliados: cor da casca, firmeza, perda de matéria fresca, sólidos solúveis, acidez titulável, açúcares totais e amido. Os frutos conservados a 12 ºC, com policloreto de vinila, mantiveram a coloração verde da casca até o 18º dia, apresentaram menor perda de massa de matéria fresca e firmeza da casca e menor teor de sólidos solúveis e acidez titulável, em relação aos frutos armazenados a 25 ºC. A utilização da embalagem, associada à temperatura de 12 ºC, permite um período seguro de 18 dias de conservação, com adequada manutenção dos atributos físicos e químicos. Os frutos armazenados a 25 ºC conservaram-se por seis dias. A película de PVC, associada ao armazenamento de 12 ºC, pode ser utilizada para atrasar o amadurecimento dos frutos por 18 dias, mantendo sua qualidade. Os frutos que permaneceram armazenados, por seis dias, a 25 ºC com, ou sem, PVC, não apresentaram características físicas e químicas desejáveis.Sweetsop fruits show limitations to the distribution to distant markets due to their fast ripening, which turns them very soft and difficult to handle without the occurrence of damage, with their conservation extremely reduced.

    Full Text Available Técnicas FT-IR (UATR, PAS e MIC, com objetiva ATR foram escolhidas para a caracterização da superfície da borracha de EPDM vulcanizada, após tratamento em plasma de Ar/O2 e N2/H2/Ar gerado em micro-ondas. Após tratamento, grupos oxigenados foram detectados por UATR e MIC/FT-IR, com objetiva ATR para as duas misturas gasosas, e possíveis grupos nitrogenados foram inseridos na superfície das amostras tratadas com plasma de N2/H2/Ar. A análise MIC/FT-IR sugeriu a formação de grupos em uma camada mais externa, para as amostras tratadas com plasma de N2/H2/Ar, sendo possível observar a redução na intensidade das bandas da absorção do CH2 e CH3, o que pode estar relacionado ao fato de o nitrogênio ser um gás menos permeável que o oxigênio. Diferentes velocidades, 0,05 cm.s-1 e 0,2 cm.s-1, foram utilizadas na análise PAS para avaliar a superfície após tratamento, e apenas para a velocidade 0,05 cm.s-1 com plasma de Ar/O2 alterações espectroscópicas foram detectadas. A redução na medida de ângulo de contato e o aumento na resistência ao descascamento da colagem indicaram melhoras nas propriedades adesivas da superfície. Falhas de adesão foram observadas entre a interface do filme de adesivo de PU e da borracha de EPDM, e confirmados por UATR/FT-IR.

Oso Grande. Os frutos eram provenientes de uma lavoura comercial do Município de Farroupilha, RS. No primeiro experimento, utilizaram-se vidros de 1.700 mL de capacidade para a armazenagem, e no segundo, empregaramse sacos de polietileno, de 53 cm x 90 cm e 90 mim de espessura. As atmosferas com 3 kPa O2 + 10 kPa CO2 ou 5 kPa O2 + 15 kPa CO2 apresentaram bom potencial para a conservação dos frutos por até 7 dias. A modificação da atmosfera em embalagens de polietileno empregando concentrações iniciais de ar ambiente aumentou o período de conservação e manteve a qualidade dos frutos por até 7 dias. Os benefícios decorrentes da utilização dessas atmosferas foram a manutenção da firmeza da polpa, da coloração dos frutos, dos teores de açúcares totais, e de ácido ascórbico.

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

A partir de los apellidos de las parejas consignadas en fuentes primarias de información, se estimó la isonimia conyugal o marital, el coeficiente total Ft y sus componentes Fr (inbreeding azaroso y Fn (inbreeding no azaroso. De las localidades estudiadas, en la Puna se ha detectado sólo una pareja isónima en una de ellas, en el Valle Calchaquí, tres y ninguna en el Valle de Lerma. Tanto en el Valle Calchaquí como en el de Lerma, se han estimado valores negativos de Ft, y en la Puna se registran los valores más elevados. En las localidades estudiadas no se cumple el supuesto de transmisión patrilineal de apellidos por lo que los valores de Fr y por ende de Ft podrían estar subestimados. Es por ello que sería necesario contar con información desde otras vertientes metodológicas para corroborar, complementar y manejar cuidadosamente el análisis de los datos y las conclusiones que se obtienen.

Participants with pathological MRI findings after the marathon, troponin elevations or detected cardiac arrhythmias will be asked to undergo cardiac MRI to rule out structural abnormalities. A follow-up is scheduled after one year. Results Here we report the baseline data of the enrolled 110 athletes aged 36-61 years. Their mean age was 48.8 ± 6.0 years, 24.5% were female, 8.2% had hypertension and 2.7% had hyperlipidaemia. Participants have attended a mean of 7.5 ± 6.6 marathon races within the last 5 years and a mean of 16 ± 36 marathon races in total. Their weekly running distance prior to the 38th BMW BERLIN-MARATHON was 65 ± 17 km. Finally, 108 (98.2% Berlin Beat-Study participants successfully completed the 38th BMW BERLIN-MARATHON 2011. Discussion Findings from the “Berlin Beats of Running” study will help to balance the benefits and risks of extensive endurance sport. ECG-recording during the marathon might contribute to identify athletes at risk for cardiovascular events. MRI results will give new insights into the link

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

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

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

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

    Within the framework of the multidisciplinary research project 'Forest ecosystems near agglomerations' carried out at the Technical University of Berlin, modifications of the herbaceous layer were investigated with regard to different spaces and times. Available results on factors of light, water, and nutrients, and regarding biotic, climatic, and logging-dependent disturbances of investigated stands were complemented by phytosociological, stand-sociological, population-biological and light-climatic investigations in experimental sites covering 400 m{sup 2} each. Here the direct relationship between relative light consumption and the closedness of the herbaceous layer could be confirmed. Cluster analyses of floristic similarity showed good agreement with floral-statistics and ecological parameters and correlations to the growth of trees and to the pH value of the upper soil. The expected zoning of vegetation near the stems of trees was confirmed. The stability of populations in relation to time seems to be a function of weather-dependent variations of nitrogen mineralization rates. The repetition of vegetation surveys from the fifties shows a stronger growth of more shadow-tolerant vegetation because of a now denser tree canopy and shrubbery. (JH).

    The 2017 Berlin Concussion in Sport Group Consensus Statement provides a global summary of best practice in concussion prevention, diagnosis and management, underpinned by systematic reviews and expert consensus. Due to their different settings and rules, individual sports need to adapt concussion guidelines according to their specific regulatory environment. At the same time, consistent application of the Berlin Consensus Statement’s themes across sporting codes is likely to facilitate superior and uniform diagnosis and management, improve concussion education and highlight collaborative research opportunities. This document summarises the approaches discussed by medical representatives from the governing bodies of 10 different contact and collision sports in Dublin, Ireland in July 2017. Those sports are: American football, Australian football, basketball, cricket, equestrian sports, football/soccer, ice hockey, rugby league, rugby union and skiing. This document had been endorsed by 11 sport governing bodies/national federations at the time of being published. PMID:29500252

    Full Text Available El incremento progresivo en el número de personas que viajan a países tropicales ha hecho que las enfermedades importadas adquieran una relevancia cada vez mayor. Las miasis (o infestaciones por larvas de moscas cutáneas se encuentran entre este tipo de enfermedades siendo especialmente frecuentes en países tropicales. A propósito de la observación de un caso de miasis cutánea masiva por Cordylobia antropophaga, que ocurrió en una mujer de 34 años de edad al volver de un viaje a Senegal, se ha efectuado una revisión de los casos de miasis cutáneas forunculoides importadas publicados en España, así como de la biología, patología, tratamiento y prevención de la miasis humana por Cordylobia anthropophaga. El caso referido, se caracterizó por la infestación con un número inusualmente elevado de larvas, no sospechándose su etiología hasta la fase final de la enfermedad. La emergencia continuada de larvas (se recogieron 91 generó en la paciente un estado de ansiedad importante. Finalmente, la eliminación de las larvas provocó una rápida mejoría de la paciente. Aunque los casos de miasis cutánea no tienen la gravedad de otras enfermedades importadas, su conocimiento es necesario desde el punto de vista preventivo, diagnóstico y terapeútico. Es importante proceder a la identificación morfológica de las larvas diferenciándolas de otro tipo de miasis con implicaciones terapéuticas diferentes.

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

    Directory of Open Access Journals (Sweden)

    Friedemann Kunst

    2016-10-01

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

    Kardjilov, Nikolay

    2012-01-01

    Neutron imaging is a non-destructive investigation method with a fast growing application field in materials research and fundamental science. The method is used broadly in the cultural heritage research as complementary technique to x-ray imaging. The ability of neutron beam to transmit thick layers of metal and the sensitivity to light elements makes the technique unique for detection of organic substances in metal and stone matrices. The high penetration power of neutrons allows for investigation of samples with real dimensions of about 100 cm3. The neutron imaging in cultural heritage helps to provide information about manufacturing processes and material properties which is very important for further restoration and conservation of the objects. The development of new methods like energy selective imaging and grating interferometry and the application of autoradiography increase the potential of the method for characterization of cultural heritage samples. The neutron tomography instrument CONRAD has been in operation since 2005 at the Hahn-Meitner research reactor at Helmholtz-Zentrum Berlin (HZB). Over the last 5 years, significant development work has been performed to expand the radiographic and tomographic capabilities of the beamline. New techniques have been implemented, including imaging with polarized neutrons, Bragg-edge mapping, high-resolution neutron imaging and grating interferometry. These methods together with the autoradiography have been provided to the user community as tools to help address scientific problems particularly in the field of cultural heritage and palaeontology. Descriptions and parameters of the facilities are given

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

    Science.gov (United States)

    Rosol, Marit

    2010-01-01

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

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

    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.

    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.

    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.

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

    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.

    Background: Polytrauma patients are expected to have a higher risk of mortality than that obtained by the summation of expected mortality owing to their individual injuries. This study was designed to investigate the outcome of patients with polytrauma, which was defined using the new Berlin definition, as cases with an Abbreviated Injury Scale (AIS) ≥ 3 for two or more different body regions and one or more additional variables from five physiologic parameters (hypotension [systolic blood pressure ≤ 90 mmHg], unconsciousness [Glasgow Coma Scale score ≤ 8], acidosis [base excess ≤ -6.0], coagulopathy [partial thromboplastin time ≥ 40 s or international normalized ratio ≥ 1.4], and age [≥70 years]). Methods: We retrieved detailed data on 369 polytrauma patients and 1260 non-polytrauma patients with an overall Injury Severity Score (ISS) ≥ 18 who were hospitalized between 1 January 2009 and 31 December 2015 for the treatment of all traumatic injuries, from the Trauma Registry System at a level I trauma center. Patients with burn injury or incomplete registered data were excluded. Categorical data were compared with two-sided Fisher exact or Pearson chi-square tests. The unpaired Student t -test and the Mann-Whitney U -test was used to analyze normally distributed continuous data and non-normally distributed data, respectively. Propensity-score matched cohort in a 1:1 ratio was allocated using the NCSS software with logistic regression to evaluate the effect of polytrauma on patient outcomes. Results: The polytrauma patients had a significantly higher ISS than non-polytrauma patients (median (interquartile range Q1-Q3), 29 (22-36) vs. 24 (20-25), respectively; p Polytrauma patients had a 1.9-fold higher odds of mortality than non-polytrauma patients (95% CI 1.38-2.49; p polytrauma patients, polytrauma patients had a substantially longer hospital length of stay (LOS).

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

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

    2017-04-01

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

    2014-05-01

    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.

    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.

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

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

    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.

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

    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.

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

Com o objetivo de avaliar o efeito de concentrações de Zn (0,4 ; 1,3 e 2,3 mimol Zn L-1 na solução nutritiva sobre o crescimento, produção de matéria seca, eficiência de absorção, translocação e utilização de Zn e P em dois cultivares de café (Coffea arabica cv. Catuaí e Coffea canephora cv. Conilon, foi realizado um experimento sob delineamento inteiramente casualizado com esquema fatorial 3 × 2 (três doses de Zn e dois cultivares com três repetições. Plantas de café dos dois cultivares estudados foram cultivadas em casa de vegetação, com solução nutritiva completa por 50 dias, após os quais receberam solução nutritiva modificada com três doses de Zn. Aos 114 dias após a transferência para a solução nutritiva modificada, as plantas foram coletadas e separadas em folhas superiores, inferiores, caule e raízes. Foram avaliadas altura do caule, número de ramificações laterais, área foliar, produção de matéria seca e conteúdos de P e Zn nas diversas partes da planta, além das eficiências de absorção, translocação e utilização de P e Zn. A dose 2,3 mimol Zn L-1 proporcionou os maiores valores para as características de crescimento avaliadas, tanto para o cultivar Catuaí, quanto para Conilon. Os maiores conteúdos de Zn observados no Catuaí indicam que este é mais exigente em Zn que o Conilon na fase de mudas. O Conilon apresentou menores eficiências de absorção e translocação e maior eficiência de utilização de Zn, refletindo sua menor demanda por este nutriente. As concentrações de Zn empregadas neste experimento não promoveram interação Zn-P.

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

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

    This study aimed to compare the efficiency of the STOP-BANG and Berlin Obstructive Sleep Apnoea Syndrome questionnaires for evaluating potential respiratory complications during the perioperative period. Questionnaires that are used to determine obstructive sleep apnoea risk are not widely used for surgical patients. Among the questionnaires that are commonly used for obstructive sleep apnoea screening, it remains unclear whether the STOP-BANG or Berlin Obstructive Sleep Apnoea Syndrome questionnaire is more effective in terms of ease of use, usage period and diagnosis of surgical patients with obstructive sleep apnoea risk. This study was designed as a descriptive and prospective study. The study included 126 patients over 18 years of age who were American Society of Anesthesiologists classification class I-II and underwent laparoscopic cholecystectomy. To determine the potential obstructive sleep apnoea syndrome risk, the STOP-BANG and Berlin questionnaires were administered. Respiratory complications were then observed during the perioperative period. During intubation and extubation, we observed statistically significant differences in difficult intubation, difficult facemask ventilation and desaturation frequency between the high- and low-risk groups for obstructive sleep apnoea syndrome, as determined by the STOP-BANG questionnaire. During extubation, statistically significant differences in coughing, breath-holding and desaturation frequency were observed between the high-risk and low-risk groups, according to the Berlin questionnaire. In the post-anaesthesia care unit, both questionnaires found statistically significant differences between the low- and high-risk groups. Obstructive sleep apnoea syndrome screening questionnaires administered during the preoperative period are useful for predicting perioperative respiratory complications. It may be most useful to administer the STOP-BANG questionnaire as the initial evaluation. Questionnaires may be used to

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

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

    The increased risk of mental health problems in children and adolescents with intellectual disability (ID) has been reported in several studies. However, almost no research has been conducted on parents' experiences with the general mental health system. We have investigated the prevalence of emotional and behavioural problems in children with ID as well as the availability and quality of mental health care from the parents' point of view. Teachers of specialised schools for ID in Berlin were asked to complete the Teacher's Report Form (TRF) of the Child Behavior Checklist. Information was collected for 1226 children and adolescents aged 6-18 years with mild to profound ID (response 70.5%). The availability and quality of mental health care was assessed by a questionnaire given to parents who had already been seeking help for their children. A total of 330 parents completed the questionnaires (response 62.0%). In addition to univariate analysis, we conducted multiple logistic regressions regarding the psychopathology reported by teachers (TRF-syndrome scales) and difficulties concerning mental health care reported by parents for a paired sample of 308 children. Overall, 52.4% of the children and adolescents with ID had a total problem score on the TRF in the deviant range (47.1% when eliminating four items reflecting cognitive deficits). Compared with the general population normative sample of children, this is a three-time higher prevalence. The most striking problems were thought problems (schizoid and obsessive-compulsive), aggressive behaviour, attention problems and social problems. Parents whose children had more severe behavioural or emotional dysfunction reported more difficulties with the mental health system. From the parents' point of view, mental health professionals frequently did not feel responsible or were not sufficiently skilled for the treatment of children with ID. As a consequence, 96% of all parents were longing for specialised in- and

    In the context of increasing greenhouse gas emission and global demographic change with the simultaneous trend to urbanization, it is a big challenge for cities around the world to perform modifications in energy supply chain and building characteristics resulting in reduced energy consumption and carbon dioxide mitigation. Sound knowledge of energy resource demand and supply including its spatial distribution within urban areas is of great importance for planning strategies addressing greater energy efficiency. The understanding of the city as a complex energy system affects several areas of the urban living, e.g. energy supply, urban texture, human lifestyle, and climate protection. With the growing availability of 3D city models around the world based on the standard language and format CityGML, energy system modelling, analysis and simulation can be incorporated into these models. Both domains will profit from that interaction by bringing together official and accurate building models including building geometries, semantics and locations forming a realistic image of the urban structure with systemic energy simulation models. A holistic view on the impacts of energy planning scenarios can be modelled and analyzed including side effects on urban texture and human lifestyle. This paper focuses on the identification, classification, and integration of energy-related key indicators of buildings and neighbourhoods within 3D building models. Consequent application of 3D city models conforming to CityGML serves the purpose of deriving indicators for this topic. These will be set into the context of urban energy planning within the Energy Atlas Berlin. The generation of indicator objects covering the indicator values and related processing information will be presented on the sample scenario estimation of heating energy consumption in buildings and neighbourhoods. In their entirety the key indicators will form an adequate image of the local energy situation for

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

    Full Text Available La osteomalacia inducida por tumor es una rara enfermedad del metabolismo óseo caracterizada por el aumento en la excreción de fosfato a nivel renal seguido de hipofosfatemia. Es causada por agentes fosfatúricos producidos por determinados tumores. La resección total del tumor resulta en la completa reversión de las anormalidades bioquímicas, la desaparición de las manifestaciones clínicas y los hallazgos en los estudios por imágenes. Presentamos el caso de un varón de 61 años con cuadro clínico y laboratorio compatibles con osteomalacia oncogénica inducida por tumor mesenquimático de localización rinosinusal. En nuestro caso el diagnóstico histológico correspondió a una neoplasia de tipo vascular: hemangiopericitoma.

    Full Text Available A superfície de uma borracha de etileno-propileno-dieno (EPDM vulcanizada foi modificada via plasma por microondas, com gases Ar, Ar/O2, N2/O2 e N2/H2, tendo como objetivo melhorar as propriedades adesivas da superfície. A técnica FT-IR/UATR foi escolhida para caracterizar as superfícies após tratamento, pois apresentou menor interferência dos ingredientes da formulação da EPDM, dentre as técnicas analisadas (ATR/KRS-5 e Ge. Grupos oxigenados foram inseridos na superfície da amostra tratada, mesmo quando não foi utilizado o oxigênio, pois estes grupos foram formados quando a superfície ativada foi exposta à atmosfera. Já em tratamentos contendo N2, grupos oxigenados e possíveis grupos nitrogenados foram identificados por FT-IR. Redução nos valores do ângulo de contato, aumento no trabalho de adesão e aumento no ensaio de resistência ao descascamento (EPDM × Poliuretano foram observados após tratamento com Ar e N2/H2, resultando em melhora nas propriedades adesivas da superfície tratada.The surface of a vulcanized ethylene propylene diene monomer (EPDM rubber was modified by microwave plasma in Ar, Ar/O2, N2/O2 and N2/H2 in order to improve the adhesion properties. Surface modification was characterized by FT-IR/UATR, because this technique showed smaller interference of ingredients of EPDM formulation in comparison with other techniques used (ATR KRS-5 and Ge. Oxygenated groups were introduced in the EPDM surface after treatment, even in treatments without oxygen. Theses groups were formed when the activated surface was exposed to the atmosphere. In treatments with nitrogen, oxygenated and possible nitrogenated groups were identified by FT-IR. Reduction in the contact angle, increase in the work of adhesion and increase in the peel strength (EPDM × Polyurethane were observed after treatment with Ar and N2/H2, resulting in improved adhesion properties of the modified surface.
